DETAILED DESCRIPTION

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and/or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and/or settings discussed in itself. In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can appreciate the applicability of other processes and/or the use of other materials.

Hereinafter, with reference to the accompanying drawings, the transmission assembly 100 of the handle device 200 according to an embodiment of the present application is described, wherein the transmission assembly 100 and the handle 2 are arranged in the handle device 200, and the handle device 200 is installed on the vehicle door body, the vehicle door body is provided with a lock cylinder 101, and the vehicle body is provided with a locking portion that cooperates with the lock cylinder 101, and the lock cylinder 101 is extended to cooperate with the locking portion so that the vehicle door body is locked, for example, when the lock cylinder 101 is retracted, it is disengaged from the locking portion so that the vehicle door body can be opened. The door lock push rod 9 can move to at least drive the lock cylinder 101 to retract, and when the door lock push rod 9 moves to drive the lock cylinder 101 to retract, the lock cylinder 101 is unlocked so that the vehicle door body can be opened. It should be noted that the lock core 101 can be retracted or extended by the reciprocating movement of the door lock push rod 9, or the lock core 101 can be retracted only by the movement of the door lock push rod 9. When the door lock push rod 9 moves in a direction away from the lock core 101, the lock core 101 can be extended by the reset spring.

As shown in Figures 4 to 8, the transmission assembly 100 includes a base 1, a crankshaft 3, a first matching piece 31, a second matching piece 41 and a stop piece 5. The crankshaft 3 is rotatably arranged on the base 1. The output end of the crankshaft 3 is suitable for connecting with the door lock push rod 9 and driving the door lock push rod 9 to move. The first matching piece 31 is arranged at the input end of the crankshaft 3. The first matching piece 31 rotates along the axis of the crankshaft 3 as the crankshaft 3 rotates; the second matching piece 41 is configured to rotate under the action of an external force. The second matching piece 41 is suitable for cooperating with the first matching piece 31 to drive the first matching piece 31 to rotate. The first matching piece 31 drives the door lock push rod 9 to move through the crankshaft 3 to achieve unlocking; the stop piece 5 is arranged on the crankshaft 3 and rotates synchronously with the crankshaft 3. When the transmission assembly 100 is in the initial locked state, the stop piece 5 stops. On the base 1, the stop member 3 limits the rotation of the crankshaft 3, thereby ensuring that the first mating member 31 returns to the initial position when the transmission assembly 100 returns to the initial locked state, that is, the position of the first mating member 31 returns to the position when the transmission assembly 100 is in the initial locked state, so that the first mating member 31 is more accurately restored to the initial position under the action of the reset force to ensure the accuracy of the next unlocking, for example, to avoid the second mating member 41 from contacting the first mating member 31 and pushing the first mating member 31 to rotate to accidentally unlock during the switching process from the initial locked state to the unlocked state, or the second mating member 41 pushes the first mating member 31 to move an insufficient distance and fails to unlock, thereby ensuring the reliability and accuracy of unlocking the transmission assembly 100.

Specifically, when the transmission assembly 100 switches from the locked initial state to the unlocked state, the second mating piece 41 rotates toward the first mating piece 31 under the action of external force, and the second mating piece 41 contacts the first mating piece 31 to drive the first mating piece 31 to rotate, so that the second mating piece 41 drives the first mating piece 31 to rotate around the crankshaft 3, and the crankshaft 3 rotates with the first mating piece 31 to drive the door lock push rod 9 to move, and the door lock push rod 9 pushes the lock core 101 to retract to unlock the lock core 101.

According to the handle device 200 of the embodiment of the present application, the stop member 5 stops at the base 1 to limit the rotational travel of the crankshaft 3, so that the first matching member 31 can return to the initial position after unlocking to prepare for the next unlocking, thereby avoiding the handle device 200 from being unlocked prematurely or unable to be unlocked, and improving the reliability and accuracy of unlocking the transmission assembly 100.

In some embodiments, as shown in FIG. 7 , the transmission assembly 100 further includes a buffer 11, which is disposed on the base 1. When the handle 2 is in the initial locked state, the stop member 5 stops at the buffer 11 to reduce the collision impact between the stop member 5 and the base 1, thereby This is beneficial to reducing the noise generated when the stop member 5 and the base 1 come into contact, thereby reducing the noise when the vehicle door body is unlocked, and improving the user experience.

When the handle 2 is in the initial locked state, the abutment member 5 abuts against the buffer member 11 to limit the movement of the abutment member 5 , thereby limiting the rotation of the crankshaft 3 and providing circumferential limitation for the crankshaft 3 .

Furthermore, a mounting groove is provided on the base 1, and the buffer 11 is installed in the mounting groove. For example, the mounting groove can penetrate the wall thickness of the base 1, and the buffer 11 is inserted into the mounting groove, so that the buffer 11 can be positioned and installed, thereby preventing the buffer 11 from being misplaced and unable to abut against the stop member 5.

In some embodiments, as shown in Figures 5 and 8, the stop member 5 includes a stop rib 51, and the stop member 5 stops at the base 1 through the stop rib 51 to reduce the contact area between the stop member 5 and the base 1, thereby further reducing the noise generated when the stop member 5 and the base 1 are in contact.

In some embodiments, as shown in Figures 5 and 8, the stop member 5 also includes a first limit member 52, which is rotatably inserted into the base 1 to limit the axial movement of the first limit member 52 along the crankshaft 3, thereby providing axial limitation for the crankshaft 3 through the cooperation between the first limit member 52 and the base 1.

For example, in the example of Figure 8, the base 1 forms a limiting groove 1b, and the first limiting member 52 can be rotatably inserted into the limiting groove 1b to limit the axial movement of the crankshaft 3 along the crankshaft 3. In the initial locking state, the stopping rib 51 of the stopping member 5 stops at the buffer member 11 to limit the circumferential rotation of the crankshaft 3 along the crankshaft 3.

Among them, the stop member 5 stops at the buffer member 11 provided on the base 1, and at the same time cooperates with the base 1 through the first limit member 52 to provide circumferential and axial limitations for the crankshaft 3, so as to reduce the impact of the movement of the crankshaft 3 on the preset interval between the first mating member 31 and the second mating member 41, so as to ensure that the distance between the first mating member 31 and the second mating member 41 remains unchanged in the initial locking state, reduce the possibility of premature unlocking or failure to unlock the lock core 101 due to the change in the distance between the first mating member 31 and the second mating member 41, and improve the reliability of the handle device 200.

In some embodiments, as shown in Figure 5, the transmission assembly 100 also includes a swivel arm 6, which is fixedly connected to one end of the crankshaft 3. The swivel arm 6 is suitable for rotating with the input end of the door lock push rod 9, and the output end of the door lock push rod 9 cooperates with the lock core 101. The swivel arm 6 rotates to drive the door lock push rod 9 to move, and the door lock push rod 9 moves to drive the lock core 101 to retract, so as to unlock the lock core 101.

In some embodiments, as shown in Figure 5, at least one of the crankshaft 3, the swing arm 6, the first matching part 31 and the stop member 5 is an integral part (for example, it can be an integrally processed part, etc.), so that the structural strength and stability of the crankshaft 3, the swing arm 6, the first matching part 31 and the stop member 5 are improved to increase the service life of the handle device 200. At the same time, the crankshaft 3, the swing arm 6, the first matching part 31 and the stop member 5 are an integral part, so that the number of components of the handle device 200 is reduced, the structure of the handle device 200 is simplified, thereby improving the reliability of the handle device 200 and making the handle device 200 easier to assemble.

Optionally, the crankshaft 3, the swing arm 6, the first matching member 31 and the stop member 5 are separate parts.

In the related art, the handle device drives the transmission component through the handle, and the transmission component drives the crankshaft to rotate to pull the zipper wire (such as Bowden cable) to unlock the door. However, the zipper wire is a flexible power transmission element, and the zipper wire is generally composed of two parts: a multi-strand steel wire on the inside and a plastic sleeve wrapped around the outside of the steel wire. However, during the unlocking process, the steel wire is moving, and the plastic sleeve is a fixed part, so that there is a movement matching gap between the two. When the vehicle is in a humid environment (such as rain or car washing environment), the movement gap of the zipper wire may be wet or water-infiltrated. When the vehicle is in a low temperature environment, the steel wire and the plastic sleeve will freeze, making it impossible to achieve the unlocking function.

In the present application, the handle device 200 cooperates with the rotating member 42 through the handle 2, and the rotating member 42 drives the first matching member 31 to rotate through the second matching member 41 to rotate the crankshaft 3, and the crankshaft 3 drives the door lock connecting rod through the rotating arm 6 to realize door unlocking, so that the transmission through mechanical parts ensures the reliability and stability of the transmission, and avoids the unlocking function of the handle device 200 being affected by the vehicle being in a humid and cold environment, thereby ensuring the reliability of the handle device 200.

In some embodiments, as shown in Figure 5, the handle device 200 also includes a first reset member 7, which cooperates with the crankshaft 3 to reset the crankshaft 3 to the locked initial state. It can be understood that the first reset member 7 provides a reset force to the crankshaft 3 to reset the crankshaft 3 to the locked initial state, that is, to reset the position state of the crankshaft 3 to the position state of the crankshaft 3 in the locked initial state.

It can be understood that the first reset member 7 cooperates with the crankshaft 3 to apply a reset force to the crankshaft 3, and the reset force makes the crankshaft 3 have a tendency to rotate so that the stop member 5 stops at the base 1, so that when the handle 2 is switched from the unlocked state to the pop-up state, the reset force of the first reset member 7 makes the crankshaft 3 rotate to drive the first matching member 31 to return to its initial position, and at the same time the stop member 5 stops at the base 1 to limit the rotation of the crankshaft 3, so as to ensure that the first matching member 31 accurately returns to its initial position, in preparation for the next unlocking of the vehicle door body, wherein the first matching member 31 is in the initial position, that is, the position where the second matching member 31 does not apply a rotational force to the first matching member 41, and at this time the stop member 5 stops at the base 1.

It is understandable that the crankshaft 3 can be reset to the locked initial state under the action of other external forces. For example, after unlocking is completed, a reset spring is provided at the lock core 101, and the reset spring drives the lock core 101 to extend to drive the door lock push rod 9 to move toward the base 1 to drive the crankshaft 3 to reset to the locked initial state. Alternatively, the transmission assembly 100 is also provided with a reset mechanism, and the reset mechanism enables the crankshaft 3 to reset to the locked initial state after unlocking is completed.

In some embodiments, as shown in FIG5 , the first restoring member 7 is a torsion spring and is sleeved on the crankshaft 3. The two ends of the first restoring member 7 are respectively fixed to the base 1 and the first matching member 31, so that the first restoring member 7 provides a restoring torque for the rotation of the crankshaft 3 and drives the first matching member 31 to return to the initial position, so as to ensure that the first matching member 31 returns to the initial position when the handle 2 is switched from the unlocked state to the pop-up state. The torsion spring directly acts on the first matching member 31, ensuring reliable transmission of the force.

For example, in the examples of Figures 5 and 8, the two ends of the first reset member 7 are respectively fixed to the base 1 and the first matching member 31. When the handle is switched from the unlocked state to the pop-up state, the second matching member 41 rotates toward a position away from the first matching member 31. The first reset member 7 has a reset torque to drive the crankshaft 3 to rotate. The crankshaft 3 drives the stop member 5 to rotate until the stop member 5 stops at the base 1. The stop member 5 limits the rotation of the crankshaft 3. Therefore, when the handle 2 completes the switching from the unlocked state to the pop-up state, the first matching member 31 can also be restored to its initial position to prepare for the next unlocking.

In some embodiments, as shown in Figures 6 and 7, the handle device 200 includes a handle 2 arranged on the base 1, and the transmission assembly 100 also includes a connecting rod assembly 43 and a rotating member 42. The input end of the connecting rod assembly 43 is suitable for connecting with the handle 2, and the rotating member 42 is connected to the output end of the connecting rod assembly 43. The second matching member 41 is arranged on the rotating member 42, and the connecting rod assembly 43 cooperates with the handle 2 and the rotating member 42 respectively to transmit the movement trend of the handle 2 (for example, the movement trend from the locked initial state to the unlocked state) to the rotating member 42 through the connecting rod assembly 43, so as to drive the rotating member 42 to rotate, so that the second matching member 41 rotates with the rotating member 42, so that the second matching member 41 pushes the first matching member 31 to rotate, thereby achieving unlocking.

In some embodiments, as shown in Figure 4, the second mating piece 41 includes a first part 411 and a second part 412 with an angle, and the first part 411 is connected to the rotating piece 42. During the unlocking process, the first part 411 and the second part 412 can both contact the first mating piece 31 to increase the contact area between the first mating piece 31 and the second mating piece 41. At the same time, the angle between the first part 411 and the second part 412 is toward the first mating piece 31, so as to improve the reliability and stability of the second mating piece 41 driving the first mating piece 31 to rotate, so as to ensure the reliability of the unlocking process.

In some embodiments, as shown in FIG. 7 , the transmission assembly 100 further includes a second reset member 8, which cooperates with the base 1 and the connecting rod assembly 43 respectively. The second reset member 8 drives the connecting rod assembly 43 to drive the handle 2 to rotate toward the pop-up state, so as to drive the connecting rod assembly 43 to move through the reset torque of the second reset member 8, so as to drive the handle 2 to return from the unlocked state to the pop-up state, and realize the automatic reset of the handle 2 after the door body is unlocked. Of course, it can be understood that the setting position of the second reset member 8 is not limited to this, for example, the second reset member 8 can also directly act on the handle 2 to drive the handle 2 to rotate from the unlocked state to the pop-up state.

In some embodiments, as shown in Figure 7, the connecting rod assembly 43 includes a first connecting rod 431 and a second connecting rod 432, one end of the first connecting rod 431 is rotationally matched with the handle 2, the other end of the first connecting rod 431 is rotationally matched with one end of the second connecting rod 432, and the other end of the second connecting rod 432 is sleeved on the rotating member 42, so as to transmit the movement trend of the handle 2 (for example, switching from the locked initial state to the unlocked state, etc.) to the rotating member 42, so that the rotation of the rotating member 42 drives the second matching member to rotate so that the second matching member 41 and the first matching member 31 are relatively matched to complete the unlocking.

For example, in the examples of Figures 3 and 7, one end of the first connecting rod 431 is connected to one end of the handle 2 by an axle pin, and the first connecting rod 431 and the handle 2 are rotatably matched, the other end of the first connecting rod 431 is connected to one end of the second connecting rod 432 by an axle pin, and the first connecting rod 431 and the second connecting rod 432 are rotatably matched, and the other end of the second connecting rod 432 is sleeved on the rotating member 42 and rotates together with the rotating member 42. When the handle 2 is switched from the locked initial state to the unlocked state, the handle 2 drives the first connecting rod 431 to move, and the first connecting rod 431 drives the second connecting rod 432 to move. One end of the second connecting rod 432 rotates toward the handle 2, and the second connecting rod 432 drives the rotating member 42 to rotate relative to the base 1 to drive the second matching member 41 to approach the first matching member 31. When the second matching member 41 completes an idle stroke and is in contact with the first matching member 31, the handle 2 continues to move in the direction away from the base 1, and the second matching member 41 drives the first matching member 31 to rotate around the crankshaft 3. The crankshaft 3 rotates with the first matching member 31 to drive the door lock push rod 9 to move, and the door lock push rod 9 pushes the lock cylinder 101 to retract to unlock the lock cylinder 101.

In some embodiments, as shown in Figure 7, the second reset member 8 is a torsion spring, and the two ends of the second reset member 8 are respectively fixed to the base 1 and the second connecting rod 432, so that the second reset member 8 provides a reset torque for the rotating member 42 and the connecting rod assembly 43 to rotate together to drive the handle 2 to return to the pop-up state, so that the handle 2 automatically switches from the unlocked state to the pop-up state, in preparation for the handle 2 to switch from the pop-up state to the locked initial state.

For example, in the examples of Figures 6 and 7, a slot structure 432a is provided on the second connecting rod 432, and the two ends of the second reset member 8 are respectively fixed to the base 1 and the slot structure 432a. In the process of switching from the unlocked state to the locked initial state, the second reset member 8 has a reset torque to drive the rotating member 42 and the second connecting rod 432 to rotate. The second connecting rod 432 rotates to drive the first connecting rod 431 to move toward the rotating member 42. The first connecting rod 431 drives the handle 2 to rotate toward the base until the handle 2 returns to the locked initial state. At this time, the handle 2 switches from the unlocked state to the locked initial state, and the second matching member 41 rotates with the rotating member 42, so that the second matching member 41 automatically returns to the position of the second matching member 41 when the handle 2 is in the unlocked state after the unlocking is completed. When the second matching member 41 is in the locked initial state, the second matching member 41 is automatically restored to the position of the second matching member 41 when the handle 2 is in the locked initial state.

It should be noted that, in the process of the handle 2 switching from the unlocked state to the locked initial state and the first mating piece 31 and the second mating piece 41 recovering from the unlocked state position to the locked initial state position, no interference occurs between the first mating piece 31 and the second mating piece 41, and the relative movement between the first mating piece 31 and the second mating piece 41 is not affected.

It should be noted that the structure of the connecting rod assembly 43 is not limited to this. For example, the connecting rod assembly 43 can be a three-link assembly, or the connecting rod assembly 43 can include an eccentric wheel structure, as long as the torque of the handle can be transmitted to the crankshaft 3.

According to the second aspect of the present application, the handle device includes: a handle 2 and a transmission assembly 100. The handle 2 can be movably mounted to the base 1, and the handle 2 can be moved so that the handle device 200 can be switched between a locked initial state and an unlocked state; the transmission assembly 100 is the transmission assembly 100 according to the first aspect of the present application, and the handle 2 cooperates with the second mating piece 41 to drive the second mating piece 41 to rotate.

According to the handle device 200 of the embodiment of the present application, the accuracy and reliability of unlocking the handle device 200 are improved by adopting the above-mentioned transmission assembly 100.

In some embodiments, as shown in FIGS. 1-3 and 7-9, the base 1 is provided with a receiving cavity 1a, and the handle device 200 also includes a pop-up state. In the initial locked state, the handle 2 is received in the receiving cavity 1a, and the handle 2 is received in the receiving cavity 1a, so that the handle 2 is hidden in the receiving cavity 1a.

In the pop-up state and the unlocked state, at least a part of the handle 2 is located outside the receiving cavity 1a to facilitate the user's operation.

It is understandable that, in the pop-up state, the handle 3 can be arranged parallel to the door body, or can be arranged at a certain angle to the door body, without specific limitation here, as long as at least a part of the handle 3 is located outside the accommodating cavity.

Among them, the handle 2 is movably arranged on the base 1 to switch between the locked initial state and the pop-up state. For example, an automated device such as a drive motor can be provided in the door body of the vehicle door to automatically switch the handle 2 from the locked initial state to the pop-up state or the handle 2 from the pop-up state to the locked initial state to facilitate user use; the handle 2 is rotatable relative to the base 1 to switch between the pop-up state and the unlocked state. For example, when the handle 2 is in the pop-up state, the user manually pulls the handle 2 to unlock the vehicle door.

In the initial locking state, a gap is provided between the first mating piece 31 and the second mating piece 41. The second mating piece 41 rotates through the preset gap from the initial locking state to drive the first mating piece 31 to rotate. The first mating piece 31 drives the door lock push rod 9 to move through the crankshaft 3 to achieve unlocking.

Specifically, when the driving handle 1 switches from the locked initial state to the pop-up state, the handle 2 cooperates with the connecting rod assembly 43 to drive the rotating part 42 to rotate, and the rotating part 42 rotates to drive the second matching part 41 to rotate toward the first matching part 31. After the second matching part 41 completes a period of idle travel (the gap between the first matching part 31 and the second matching part 41), the second matching part 41 contacts the first matching part 31 to prepare for the unlocking process; when the driving handle 2 switches from the pop-up state to the unlocking state, the handle 2 continues to cooperate with the connecting rod assembly 43 to drive the rotating part 42 to rotate, and the rotating part 42 rotates to drive the second matching part 41 to rotate in the direction of the first matching part 31. At this time, the second matching part 41 and the first matching part 31 are in contact, and the second matching part 41 drives the first matching part 31 to rotate around the crankshaft 3. The crankshaft 3 rotates with the first matching part 31 to drive the door lock push rod 9 to move, and the door lock push rod 9 pushes the lock cylinder 101 to retract to unlock the lock cylinder 101.

The vehicle door according to the third aspect embodiment of the present application includes a vehicle door body, a handle device 200, a lock core 101 and a door lock push rod 9, the handle device 200 is the handle device 200 according to the above-mentioned second aspect embodiment of the present application, the base 1 is arranged on the vehicle door body; the lock core 101 is arranged on the vehicle door body, and a guide groove is arranged on one of the lock core 101 and the vehicle door body; the input end of the door lock push rod 9 is connected to the rotating arm 6 fixedly connected to the crankshaft 3, and the output end of the door lock push rod 9 is arranged in the guide groove, and the output end of the door lock push rod 9 can at least realize the unlocking of the vehicle door when the guide groove moves.

According to the vehicle door of the embodiment of the present application, the reliability of unlocking the vehicle door is improved by adopting the handle device 200 mentioned above.

The vehicle according to the fourth aspect embodiment of the present application includes the vehicle door as described in the third aspect embodiment of the present application.

Of course, when the handle 2 is in the locked initial state and the pop-up state, the door lock push rod 9 does not move, such as shown in position D in Figure 9. When the handle 2 is in the unlocked state, the door lock push rod 9 pushes the lock cylinder 101 to unlock, such as shown in position E in Figure 9.

In the locked initial state, the first mating piece 31 and the second mating piece 41 are spaced apart, and the spacing distance between the first mating piece 31 and the second mating piece 41 is a preset spacing distance. When the handle 2 switches from the locked initial state to the pop-up state, the handle 2 drives the first connecting rod 431 to move in the direction away from the base 1, the first connecting rod 431 drives the second connecting rod 432 to rotate toward the handle 2, and the second connecting rod 432 drives the rotating piece 42 to rotate relative to the base 1 to drive the second mating piece 41 to rotate toward the first mating piece 31. After the second mating piece 41 completes a period of idle travel (the interval between the first mating piece 31 and the second mating piece 41), the second mating piece 41 is in contact with the first mating piece 31 to prepare for the unlocking process.

When the user releases the handle 2, the reset torque of the first reset member 7 drives the crankshaft 3 to rotate, and the crankshaft 3 rotates to drive the first matching member 31 and the stop member 5 to rotate toward the base 1 until the stop member 5 stops at the base 1. At this time, the first matching member 31 returns to its initial position, and at the same time, the reset torque of the second reset member 8 drives the rotating member 42 to rotate in a direction away from the first connecting rod 431, and the rotating member 42 rotates to drive the second matching member 41 and the second connecting rod 432 to rotate in a direction away from the first matching member 31, and the second connecting rod 432 rotates to drive the first connecting rod 431 to move in the direction of the rotating member 42, and the first connecting rod 431 moves to drive the handle 2 to move in a direction close to the base 1, until the handle 2 switches from the unlocked state to the pop-up state, and at this time the second matching member 41 moves to the position of the second matching member 41 when the handle 2 is in the pop-up state.

When the handle 2 switches from the pop-up state to the locked initial state, the handle 2 gradually retracts into the accommodating cavity 1a of the base 1, and the first connecting rod 431 moves toward the direction of the rotating member 42 to drive the second connecting rod 432 to rotate, and the second connecting rod 432 rotates to drive the rotating member 42 to rotate and reset in the direction away from the first connecting rod 431, and the rotating member 42 rotates to drive the second matching member 41 to return to the initial position.

In addition, the handle 2 and the door lock push rod 9 are transmitted through the transmission assembly 100, which avoids friction between the internal components of the handle device 200 and reduces the noise of the handle device 200 when unlocking and locking.

The handle device 200 provided in the embodiment of the present application includes a handle 2, a transmission assembly 100 and a door lock push rod 9; the transmission assembly 100 includes a rotating member 42 and a transmission shaft 110, the input end of the rotating member 42 is connected to the handle 2, for example, when the handle 2 is pulled, the rotating member 42 can be driven to rotate through a transmission mechanism; the handle device 200 composed of the handle 2 can drive the rotating member 42 to rotate, the output end of the rotating member 42 is connected to the input end of the transmission shaft 110, the rotating member 42 can drive the transmission shaft 110 to rotate, the input end of the door lock push rod 9 is connected to the output end of the transmission shaft 110, and the transmission shaft 110 can drive the door lock push rod 9 to move to unlock the lock 201. The handle device 200 uses the transmission assembly 100 to realize the transmission of the handle 2 and the door lock push rod 9, which simplifies the structure of the handle device 200 and improves the assembly efficiency and unlocking reliability of the handle device 200.

Specifically, since the handle device 200 has many parts that cooperate with each other at the location where it is installed on the vehicle, in order to fully utilize the In the assembly space of the handle device 200, the setting directions of the rotating member 42 and the transmission shaft 110 may be different, that is, the rotating member 42 and the transmission shaft 110 are set at an angle. In addition, in order to facilitate the transmission between the rotating member 42 and the transmission shaft 110 in different directions, the rotating member 42 and the transmission shaft 110 can be connected by the steering mechanism, for example, the second matching member 41 is connected to the rotating member 42, the first matching member 31 is connected to the transmission shaft 110, the rotation axis of the rotating member 42 is also the rotation axis of the second matching member 41, and the rotation axis of the transmission shaft 110 is also the rotation axis of the first matching member 31, so that when the rotating member 42 and the transmission shaft 110 form a transmission angle, that is, the rotation axis of the second matching member 41 and the rotation axis of the first matching member 31 form a transmission angle, stable transmission between the rotating member 42 and the transmission shaft 110 can still be guaranteed.

Specifically, in one embodiment, the second mating member 41 is a protrusion 413, and the first mating member 31 is a cam 311. When the handle 2 is pulled, it can drive the rotating member 42 and the protrusion 413 on the rotating member 42 to rotate. Since the protrusion 413 cooperates with the cam 311, the protrusion 413 can drive the cam 311 to rotate when it rotates. When the cam 311 and the transmission shaft 110 rotate synchronously, the transmission shaft 110 can be connected to the door lock push rod 9 to push the door lock push rod 9 to move, and the lock 201 can be unlocked by rotating the transmission shaft 110, thereby improving the unlocking efficiency of the handle device 200.

Specifically, the handle 2 can drive the rotating member 42 and the second bevel gear on the rotating member 42 to rotate when being pulled. Since the second bevel gear cooperates with the first bevel gear, the second bevel gear can drive the first bevel gear to rotate when rotating. When the first bevel gear and the transmission shaft 110 rotate synchronously, the door lock push rod 9 can be pushed to move through the transmission connection between the transmission shaft 110 and the door lock push rod 9. The lock 201 can be unlocked by rotating the transmission shaft 110, thereby improving the unlocking efficiency of the handle device 200.
