Description

Door lock mechanism, vehicle door assembly and vehicle

Technical Field

The application relates to the technical field of vehicles, in particular to a door lock mechanism, a vehicle door assembly with the door lock mechanism and a vehicle.

Background

The hatchback body is a body design. Hatchback vehicles typically have a tailgate in addition to two to four side-opening doors. In a common two-compartment car, the tailgate is commonly referred to as a tailgate or backdoor, etc.; in a three-compartment car, the tailgate is also referred to as a trunk door. The door lock of the tail door can be provided with two unlocking modes, namely electric unlocking and mechanical unlocking. The electric unlocking is applied to the normal use process of the vehicle. Based on the electric unlocking mode, a user can open the tail gate through the button, and the electric unlocking device is convenient and quick. Mechanical unlocking is typically used in emergency situations to open a tailgate from the interior of a vehicle. For example, after an accident, the door lock may not be unlocked because the vehicle cannot be powered on; at the moment, the personnel in the vehicle can open the tail door of the vehicle in a mechanical unlocking mode, so that emergency escape is realized.

Current mechanical unlocking mechanisms generally include a lock body assembly mounted inside the tailgate and a cover plate secured to the tailgate surface. After the cover plate is opened, the lock hole of the lock body assembly is exposed. The personnel in the car inserts the key (or the flat hard thing similar to key shape) into the lockhole, then rotates the key, can realize the unblock. The following three problems may exist with existing mechanical unlocking mechanisms. Firstly, the cover plate can be pried up by using a proper tool; secondly, the key is easy to lose, and a proper object can not be found in emergency, so that the key can be inserted into the lock hole; thirdly, even if the cover plate is opened and the key is held on hand, the key still needs to be aligned with the lock hole, then the key is inserted into the lock hole, and finally the key is rotated to unlock. The three problems are that precious escape time is not occupied, and life health of personnel in the vehicle can be damaged, so that the situation of irrecoverable results is caused.

Detailed Description

The following description of the embodiments of the present application will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the application are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Embodiment one

As shown in fig. 1, the door lock mechanism provided in this embodiment includes a lock body assembly 100, an operating member 200, and a rope 300. The lock body assembly 100 is mounted to a tailgate 400 of a vehicle. The operating member 200 is movably coupled to the tail gate 400 and exposed to the interior space of the vehicle. The cable 300 has a first end connected to the operating member 200 and a second end connected to the trigger 110 of the lock assembly 100. When the operating member 200 moves, the rope 300 pulls the trigger member 110, and the trigger member 110 drives the locking member 120 of the lock assembly 100 to act, so as to unlock the tail gate.

The lock body assembly provided in this embodiment has the advantage that the personnel in the vehicle only need to touch the operating member 200, so that the operating member 200 drives the pull rope 300 to pull the triggering member 100 of the lock body assembly 200, and the unlocking of the tail door 400 can be realized. Compared with the prior art, the door lock mechanism provided by the embodiment does not need any tool or key when unlocking, and does not need to insert the key into a lock hole and other operations; the mechanical unlocking operation of the tail door of the vehicle is greatly simplified, and therefore the technical problems of complex and complicated unlocking operation of the tail door mechanical unlocking mechanism of the existing vehicle are solved. In an emergency, the door lock mechanism provided by the embodiment is more beneficial to escape of personnel in the vehicle.

As shown in fig. 2, when the pull rope 300 pulls the trigger 110, the trigger 110 swings around the first rotation shaft 111, and drives the locking member 120 to act, so that the locking member 120 is separated from the lock ring 500, and unlocking is achieved. The lock ring 500 is fixed to the vehicle body. When the locking member 120 is disengaged from the locking ring 500, the vehicle tailgate may be opened.

Other portions of the lock body assembly 100, including the locking member 120, other than the trigger member 110 may be known in the art. Fig. 3 shows a prior art lock assembly having a plurality of sequentially activated transmission members. Specifically, the lock body assembly shown in fig. 3 includes a first transmission member 610, a second transmission member 620, and a third transmission member 630. The first transmission member 610 may be adapted to operate as a trigger member for a lock assembly according to the present application in accordance with the trigger member 110 shown in fig. 2. When the force-receiving end 612 of the first transmission member 610 is pulled by the rope, the first transmission member 610 swings around the second rotation shaft 611 and touches the first bump 621 on the second transmission member 620. The second transmission 620 oscillates about axis three 623. The second transmission member 620 is further fixedly provided with a second bump 622. The second bump 622 is inserted into the third transmission member 630. The third transmission member 630 is arranged coaxially with the second transmission member 620, and it also swings around the rotation axis three 623. When the second transmission member 620 swings, the second protrusion 622 drives the third transmission member 630 to swing, and activates the locking member 120. The locking piece 120 swings around the fourth rotation shaft 121 and is separated from a locking ring fixedly arranged on the vehicle body, so that unlocking is realized.

The present embodiment is not limited to the shape of the operation element, and may be plate-shaped, grip-shaped, or ring-shaped. In the present embodiment, the operating element is limited to be movably connected to the tail gate, but the moving mode is not limited. The moving mode can be translational or rotational. For example, in this embodiment, the operating member may be a pull ring that is clamped to the tail gate. The pull ring is connected with a trigger piece of the lock body assembly through a rope. When a person pulls the pull ring in the car, the tail gate can realize mechanical unlocking.

In this embodiment, as shown in fig. 4, the rope 300 may include a rope core 310 and a rope hitch 320. The cord 310 is threaded in the cord sleeve 320. The rope hitch 320 is mounted on the tailgate by a plurality of clips fixedly disposed inside the tailgate. The first end of the cord 310 is connected to the operating member and the second end is connected to the trigger of the lock assembly. When the operating member is moved, the string sheath 320 is substantially stationary, and the string core 310 moves in its length direction, thereby pulling the trigger member.

Second embodiment

Based on the first embodiment, the present embodiment improves the operation element. As shown in fig. 1 and 2, in the present embodiment, the operation member 200 is a cover plate 210. The cover 210 is embedded in the inner panel 410 of the tail gate 400 and is rotatably connected with the inner panel 410. The cover 210 pulls the rope by rotating itself.

The door lock mechanism provided in this embodiment uses the cover plate 210, and thus uses an external form of the conventional mechanical unlocking mechanism. The prior art is readily plausible and the purpose of the cover 210 is readily apparent to the consumer when viewing the cover 210. Also, in accordance with the prior art, a mark for opening the tailgate of the vehicle may be provided on the cover 210, as shown in fig. 1 and 2, so that the cover 210 is more easily recognized. In the event of an emergency, the in-vehicle personnel can quickly find the cover plate 210 and use it to unlock the tail gate of the vehicle.

Although the cover 210 is similar in shape to the cover of an existing mechanical tailgate unlocking mechanism, the methods of use are quite different. The prior art covers need to be pried off by a tool or detached from the vehicle tail gate by a certain means. The cover 210 in the present embodiment only needs to be rotated. After the cover plate in the prior art is opened, a key is further needed to unlock the tail door of the vehicle. In the present embodiment, the tailgate 210 is unlocked immediately after being rotated without further manipulation.

In the present embodiment, the cover 210 is embedded in the inner panel 410 of the tail gate 400, and the cover 210 and the inner panel 410 are integrally formed. This prevents the cover plate 210 from excessively affecting the appearance of the interior trim panel 410, which is advantageous for the simplicity and beauty of the vehicle interior trim. Specifically, the interior panel 410 may be composed of several parts; for example, it may be divided into four parts of upper, lower, left and right. The cover plate 210 is generally mounted to the lower portion. Fig. 1 is a view of the tailgate 400, looking into the vehicle interior, in a closed state of the tailgate 400. It is apparent that the cover plate 210 is located at a lower portion of the interior trim panel 410 (also a lower portion of the tail gate 400).

The door generally includes, from the exterior to the interior of the vehicle, an outer panel, an inner panel, and an interior trim panel. The outer and inner plates are typically sheet metal parts. The interior trim panel may be made of a non-metallic material. The present embodiment defines the cover 210 attached to the interior trim panel. In the first embodiment, the operation element may be attached to the inner panel of the door; the person skilled in the art can adaptively select the installation position of the operation member according to the actual situation.

The present embodiment does not limit the rotation direction of the cover plate 210. The cover 210 may rotate about a horizontal axis of rotation or may rotate about a vertically disposed axis of rotation. The cover plate 210 may rotate clockwise or reversely whether it rotates around the horizontal or vertical rotation axis.

Embodiment III

Based on the second embodiment, the present embodiment further improves the cover plate 210. As shown in fig. 5, in the present embodiment, the rope 300 is connected to the first middle portion 211 or the upper portion 212 of the cover 210 (in fig. 5, the rope 300 is connected to the first middle portion 211 of the cover 210); the lower portion 213 of the cover 210 is rotatably coupled to the interior trim panel 410. The upper portion 212 of the cover 210 has a first operating portion. When the in-vehicle occupant applies a first force F1 to the first operation site toward the in-vehicle occupant, the upper portion 212 of the cover 210 is flipped over (as shown in fig. 6) toward the outside of the tailgate, and pulls the rope 300.

In the present embodiment, the first middle portion 211 is a middle portion of the cover 210 as viewed in the up-down direction, as shown in fig. 5. In fig. 5, arrow Z1 points upward of the vehicle, and arrow Z2 points downward of the vehicle; arrow X1 points to the front of the vehicle and X2 points to the rear of the vehicle; the direction perpendicular to the paper surface is the width direction of the vehicle.

Since the cover 210 is generally disposed under the interior trim panel 410, the cover 210 is generally seen from a top view by an occupant; therefore, in the present embodiment, the first operation portion is provided at the upper portion 212 of the cover 210. Thus, the first operation portion is also seen while the vehicle occupant views the cover plate 210; so that the cover plate 210 can be quickly turned over to unlock the tail gate in a minimum amount of time.

Typically, the cover 210 is in a closed state, as shown in fig. 5. At this time, the rope 300 is in a tight state and has a pulling force toward the inside of the tailgate against the cover plate 210. This tension causes the upper portion 212 of the cover 210 to ride over the trim panel 410. Specifically, the upper portion 212 of the cover plate 210 rides over the upper edge of the mounting hole (i.e., the hole opening into the trim panel 410 for mounting the cover plate 210). The tension of the cable 300 against the cover 210 may be provided by a torsion spring mounted on the locking member of the lock body assembly.

In this embodiment, the vehicle occupant can turn the cover plate 210 to the outside of the tail gate by applying the first force F1 shown in fig. 5 to the first operation portion of the cover plate 210, so as to achieve the state shown in fig. 6, and achieve unlocking; the unlocking mode is convenient and quick.

Fourth embodiment

Based on the third embodiment, the present embodiment improves the peripheral structure of the first operation portion. As shown in fig. 5, the portion of the interior plaque 410 corresponding to the first operation portion is recessed toward the inside of the tail gate, and forms a first recess 411 capable of accommodating the end of a human finger. Specifically, the first recess 411 is formed on the upper edge of the mounting hole (i.e. the hole formed on the inner decoration board 410 for mounting the cover plate 210). As seen in fig. 5, the longitudinal section of the first recess 411 is arcuate.

The third embodiment does not limit the structure of the first operation portion. For ease of handling, the first handling site may be a protrusion from the cover plate 210. However, the protrusions are easily touched by foreign objects inside the vehicle, so that the cover plate 210 is accidentally turned over, and thus the tailgate is accidentally unlocked and opened. In order to avoid this unexpected situation, the present embodiment proposes the first concave portion 411. The first recess 411 is located inside the surface of the tailgate, and foreign materials cannot enter. Even if the sundries enter the first concave portion 411, the acting force of the sundries on the cover plate 210 must face the outside of the tail gate (i.e. the direction shown by F1) to unlock the tail gate; the probability of this occurrence is low, thereby reducing the likelihood of the occurrence of the above-described accident.

In order to further reduce the possibility of the first operation portion being touched by mistake, as an example of the present embodiment, as shown in fig. 7, the first operation portion has an elastic clamping block 214, and a clamping groove 215 is formed on the elastic clamping block 214. When the elastic clamping block 214 is in a natural state, the clamping groove 215 is clamped with the edge of the inner decoration plate 410; the cover plate 210 cannot rotate. When an occupant applies an external force F2 to the upper end of the elastic clip 214, the elastic clip 214 deforms, and the edge of the interior trim panel 410 is disengaged from the clip groove 215; at this time, the cover 210 may be turned over in the same manner as shown in fig. 5 and 6.

In this embodiment, the elastic clamping block 214 can further reduce the possibility of false touch; after the vehicle occupant applies the external force F2 to the elastic block 214 and the cover 210 can be turned over, the vehicle occupant does not need to leave the elastic block 214 and only has to change the direction of the applied force to the direction shown by F1 in fig. 5; the unlocking operation is finished at one time, and is convenient and quick.

Fifth embodiment

Based on the second embodiment, the present embodiment further improves the cover plate 210. The present embodiment and the third embodiment are parallel embodiments. As shown in fig. 8, in the present embodiment, the rope 300 is connected to the left portion 216 of the cover 210, the second middle portion 217 of the cover 210 is rotatably connected to the inner panel 410, and the right portion 218 of the cover 210 has a second operation portion. When the in-vehicle occupant applies a second force F3 against the second operating site away from the in-vehicle occupant himself, the left portion 216 of the cover 210 is flipped over towards the outside of the tailgate and pulls the cable 300.

In the present embodiment, the second middle portion 217 refers to a middle portion of the cover 210 as viewed in the width direction of the vehicle, as shown in fig. 8. In fig. 8, an arrow Y1 points to the left of the vehicle, and a arrow Y2 points to the right of the vehicle; arrow X1 points to the front of the vehicle and X2 points to the rear of the vehicle; and the vehicle is directed downwards perpendicular to the paper surface, outwards perpendicular to the paper surface and upwards.

The embodiment provides an inward pushing type unlocking mode. In the third embodiment, the unlocking mode is performed during eversion. In the third embodiment, after the hands of the person in the vehicle extend to the cover plate, the edges of the cover plate must be pulled back by fingers. In this embodiment, after the hands of the person in the vehicle extend toward the cover plate, the right portion 218 of the cover plate is simply pushed forward; this is more labor-saving to a certain extent than the unlocking method provided in the third embodiment. If the personnel in the vehicle are injured and weakened due to accidents, the unlocking mode provided by the embodiment is definitely more advantageous than the unlocking mode provided by the embodiment three.

Embodiment six

In the fifth embodiment, as shown in fig. 9, the interior panel 410 has a second recess 412, and the cover 210 is located inside the second recess 412. The opening of the second recess 412 has a shielding plate 413, and the shielding plate 413 is removably or detachably attached to the interior trim panel 410. In fig. 9, a chute 414 is provided in the inner panel 410, and a shielding plate 413 is slidable in the chute 414. After the shielding plate 413 slides leftwards for a certain distance, the right part of the cover plate 210 is exposed, and a person in the vehicle can push the right part of the cover plate 210 towards the inside of the tail gate, so that unlocking is realized.

The second recess 412 provided in this embodiment provides an installation space for the cover plate 210 located inside the interior trim panel 410, so as to prevent the cover plate 210 from protruding out of the interior trim panel 410, and thus, the simplicity and the appearance of the interior trim of the vehicle are not affected.

The shielding plate 413 provided in this embodiment has an effect of preventing the right portion of the cover plate 210 from being touched by mistake, thereby causing the vehicle tailgate to be opened accidentally. If the shielding plate 413 is not provided, the vehicle tail gate is unlocked and accidentally opened once the foreign matter in the vehicle touches and presses the right portion of the cover plate 210 toward the inside of the tail gate.

Embodiment seven

Based on the second embodiment, the present embodiment improves the cover plate. As shown in fig. 10, the cover plate 210 is rotatably coupled to the inner panel 410 through the first rotation shaft 220. The first rotating shaft 220 is sleeved with a first reset torsion spring 230. In fig. 10, the number of the first restoring torsion springs 230 is two. The first return torsion spring 230 has an effect in that the cover 210 can be automatically returned under the action of the first return spring 230 after an occupant releases the cover 210.

In the prior art, the cover plate which is required to be pried by a tool is difficult to open and difficult to install. For the prior art, when the mechanical unlocking mechanism is used, after the emergency is eliminated, the cover plate needs to be reinstalled to the tail door of the vehicle to cover the lock body assembly. But because the connection structure of the cover plate and the tail gate is complex, the installation is very difficult. Users often either abandon the installation or damage the cover plate by forced installation. In either case, the cover plate is subject to imperfections that affect the integrity and aesthetics of the vehicle interior.

In the door lock mechanism provided in this embodiment, the cover 210 can be automatically reset by the first reset torsion spring 230, which is very convenient, and after the cover 210 is reset, the interior trim of the vehicle is restored to the original state, so that the interior trim of the vehicle can be kept intact and attractive.

As an example of the present embodiment, as shown in fig. 11 to 13, the back surface of the interior panel 410 is provided with two boss portions 415. The both ends of the first rotation shaft 220 are respectively inserted into the two shaft sleeve parts 415 to achieve a rotational connection with the inner panel 410. Specifically, the boss 415 may be subjected to a root thinning process to prevent the surface of the interior trim panel 410 from shrinking.

Specifically, as shown in fig. 14, one end of the first rotating shaft 220 is provided with an anti-slip pattern 221, and is in interference fit with one of the shaft sleeve portions 415. The interference may be 0.1mm. The other end of the second rotating shaft 220 is in transition fit, so that the installation is convenient.

Specifically, the back surface of the cover 210 may be provided with two shaft mounting portions 219. The shaft mounting portion 219 is aligned with the shaft sleeve portion 415 of the interior trim panel 410, and the first shaft 220 passes through the shaft mounting portion 219 to be rotatably coupled to the cover 210.

Specifically, the back surface of the inner plaque 410 is provided with a first blocking portion 231, and the back surface of the cover plate 210 is provided with a second blocking portion 232. As shown in fig. 11, two ends of the first reset torsion spring 230 are respectively clamped in grooves of the first clamping portion 231 and the second clamping portion 232. When the cover 210 is turned outwards (inwards perpendicular to the paper surface in fig. 11), the position of the first blocking part 231 is unchanged, and the second blocking part 232 is turned inwards (outwards perpendicular to the paper surface), so that the first reset torsion spring 230 is deformed and stores elastic potential energy. When the external force applied to the cover 210 disappears, the elastic potential energy can drive the cover 210 to reset automatically.

Specifically, as shown in fig. 13, a hook 701 is provided at the rear surface of the cover plate 210 to connect the rope 300. The hook 701 is located in the middle of the cover plate 210. The middle of the hook 701 is slotted for the passage of the rope 300. The end of the rope 300 may be snap fitted with the hook 701. The back of the cover plate 210 is also provided with a reinforcing rib 702 to ensure that the cover plate 210 has sufficient strength; particularly, when the cover 210 is made of a non-metal material, the reinforcing ribs 702 can ensure that the cover 210 is strong enough to withstand the tensile force of the rope 300 or the impact of external force. The lower edge of the cover plate 210 is provided with a bending portion 703, and the second blocking portion 232 may be fixed to the bending portion 703.

Embodiment eight

Based on the first embodiment, the present embodiment improves the trigger of the lock body assembly. As shown in fig. 3, the triggering element 110 is a rotating element, which has a second rotating shaft 112, and a second reset torsion spring 640 is sleeved on the second rotating shaft 112.

The second reset torsion spring 640 can reset the trigger 110. When the trigger 110 is reset, the cable 300 can be pulled, and the cable 300 in turn pulls the operating member 200 to reset. The second return torsion spring 640 is not inconsistent with the first return torsion spring 230 provided in the seventh embodiment, and both may exist at the same time.

Embodiment nine
