Further, as shown in fig. 1, the connecting member 30 is sleeved on the spring seat 20 and can move up and down along the installation direction of the spring seat 20. Fig. 3-4 are schematic perspective views of the connecting member 30 of the inhalation device 100 according to the present invention. The connecting member 30 includes a supporting block 31, and a sleeve 32 and a connecting portion 33 fixed to upper and lower sides of the supporting block 31, respectively. The sleeve 32 is sleeved on the spring seat 20, and the connecting portion 33 is provided with a contact surface 34 capable of abutting against the push rod 240 of the clutch pump assembly 230. The sleeve 32 provided above the supporting block 31 is used to connect with the spring seat 20 so that the supporting block 31 can move in the direction in which the spring seat 20 is provided. The contact surface 34 provided on the connecting portion 33 below the supporting block 31 is used to abut against the push rod 240 of the clutch master cylinder 230, so that the push rod 240 is provided with an assist force by the suction sensing device 100. In this embodiment, one end of the spring seat 20 is fixed to the plane of the second mounting portion 12 of the fixing rod 10 by riveting, so as to achieve the fixed connection between the spring seat 20 and the fixing rod 10, and the other end of the spring seat is sleeved with the sleeve 32 of the connecting member 30, so that the connecting member 30 can reciprocate along the installation direction of the spring seat 20.

The compression spring 40 is always in a compressed state in the inhalation sensing device 100, so that the compression spring 40 always provides a continuous pushing force to the connecting member 30. Wherein the supporting block 31 of the link 30 is always urged downward in the direction in which the spring seat 20 is disposed by the compression spring 40.
The connecting bracket 50 provided in the inhalation sensing device 100 serves to support the link 30 and to match the stroke length of the inhalation sensing device 100 acting in the entire pedal formation by the rotation of the pedal 220. The movement of the link 30 on the spring seat 20 is carried out by the rotation of the pedal 220. Specifically, one end of the connecting bracket 50 is fixedly connected to the pedal 220, and the other end is disposed at the bottom of the supporting block 31 for supporting the connecting member 30. Further, as shown in fig. 3, a connection arc surface 312 is provided on a lower surface of the support block 31 on the connection member 30. Correspondingly, the connecting bracket 50 is provided with a protrusion 51 abutted against the connecting arc surface 312, and the connecting bracket 50 rotates along with the pedal 220 to drive the protrusion 51 to slide along the direction of the connecting arc surface 312, so that the contact surface 34 on the connecting piece 30 is abutted against the push rod 240 to generate a pushing force. In this embodiment, during the process of stepping on the pedal 220, the connecting bracket 50 rotates clockwise along with the pedal 220, the protrusion 51 located at the connecting member 30 translates along with the rotation of the pedal 220, so that the supporting block 31 of the connecting member 30 moves downward under the action of the compression spring 40, the contact surface 34 on the connecting member 30 abuts against the push rod 240, and the pushing force of the compression spring 40 on the connecting member 30 is finally transmitted to the push rod 240 to generate the pushing force, thereby forming the suction feeling. Conversely, when the pedal 220 is released, the pedal 220 automatically returns to the original position, and the connecting bracket 50 is driven to rotate counterclockwise along with the pedal 220, and the protrusion 51 at the connecting member 30 translates along with the rotation of the pedal 220, so that the supporting block 31 of the connecting member 30 is supported by the protrusion 51 on the connecting bracket 50 to move upward, and the contact surface 34 on the connecting member 30 is finally separated from the push rod 240.
Further, as shown in fig. 3, in the clutch pedal suction sensing device 100 according to the present invention, the connecting portion 33 of the connecting member 30 includes a mounting post 331, a first rotating shaft 332 and a switching block 333, one end of the mounting post 331 is fixed to the supporting block 31, the other end is hinged to the switching block 333 through the first rotating shaft 332, and the contact surface 34 is disposed on the switching block 333. Specifically, a notch is provided at the bottom of the adapter block 333, into which the push rod 240 can be inserted, and the contact surface 34 is disposed in the notch. The adapter 333 arranged on the connecting member 30 can move downward to contact with the push rod 240 during the stepping and rotating process of the pedal 220, and during the contacting process, the self-adapting process of the contact surface 34 and the top surface of the push rod 240 is realized through the hinge connection between the first rotating shaft 332 and the adapter 333, so that the contact surface 34 can be completely attached to the top surface of the push rod 240 during the contacting process, and the pushing force generated on the compression spring 40 in the inhalation sensing device 100 can be better transmitted to the push rod 240, thereby continuously and effectively providing the inhalation sensing for the push rod 240 during the rotating process of the pedal 220.
Further, as shown in fig. 4, in the inhalation sensing device 100 of the present invention, the lower surface of the supporting block 31 in the connecting member 30 is further provided with a pair of limiting side plates 314 located at two sides of the supporting block 31, and one end of the connecting bracket 50 having the protrusion 51 is sleeved on the mounting post 331 of the connecting portion 33 and is disposed in the pair of limiting side plates 314. Since one end of the connecting bracket 50 is fixed to the pedal 220 and the other end is limited to slide in the pair of limiting side plates 314, as shown in fig. 6, the limiting side plate 324 is used to limit the moving gap L4 of the connecting bracket 50 in the horizontal direction, and by controlling the moving gap L4 of the connecting bracket 50 in the horizontal direction during moving, the function of limiting in the horizontal direction can be achieved, so that the play of the pedal 220 in the horizontal direction is reduced, and the experience feeling when the pedal 220 is stepped on is improved.
Further, in the present embodiment, the connecting member 30 is a plastic injection molding member, and the connecting bracket 50 is a metal member, so that one end of the connecting bracket 50 connected to the pedal 220 is fixedly connected by welding or the like. And a pair of grease grooves 313 for the protrusions 51 of the connecting bracket 50 to be inserted into and slide are formed on the connecting arc surface 312 at a side of the connecting bracket 50 at the bottom of the connecting member 30. The protrusion 51 of the connection bracket 50 slides along the grease groove 313, so that the connection between the connection bracket 50 and the connection member 30 can be more smoothly and stably performed.
The inhalation feeling device 100 of the clutch pedal 220 provided by the invention can be applied to a clutch pedal assembly 200 to provide boosting force for the pedal 220 to push the push rod 240 of the clutch master cylinder 230, the opportunity for starting the inhalation feeling device 100 is controlled by stepping on the pedal 220, so that the contact surface 34 in the inhalation feeling device 100 is abutted against the push rod 240, and the compression spring 40 preset in the inhaler device is utilized to apply the pushing force to the push rod 240, so that the inhalation feeling and the stepping comfort of the pedal 220 are improved, and the fatigue feeling of the driver when stepping on the clutch pedal 220 is reduced on the premise that the force of the driver when stepping on the pedal 220 is not changed, particularly, the driver does not feel tired in the long-time use process; meanwhile, the connecting support 50 in the suction sensing device can limit the pedal 220 in the Y direction, so that the Y-direction play between the pedal 220 and the pedal 220 mounting seat 210 is reduced, and the experience of stepping on the pedal 220 is improved.
Referring to fig. 5-7, the present invention further provides a clutch pedal assembly 200, which includes a pedal mounting base 210, a pedal 220 hinged to the pedal mounting base 210 through a second rotating shaft 250, and a clutch pump assembly 230 connected to the pedal 220, wherein a push rod 240 of the clutch pump assembly 230 is hinged to the pedal 220, and the clutch pedal suction sensing device 100 disposed in the pedal 220 mounting base 210. The suction sensing device 100 is additionally arranged in the clutch pedal assembly 200, so that the pedal 220 can well provide power for pushing the push rod 240, different compression springs 40 can be selected according to different clutch pedal assemblies 200 to adjust the magnitude of the power of the suction sensing device 100, and the suction sensing device 100 can meet the power-assisting requirements of different clutch pedal assemblies 200.
Specifically, as shown in fig. 5, the first mounting portion 11 of the fixing rod 10 in the inhalation device 100 is fixedly connected to the mounting seat 210 of the pedal 220 through the connecting member 111, and the end of the connecting bracket 50 is fixedly connected to the pedal 220 and can rotate along with the pedal 220. The end of the connection bracket 50 connected to the pedal 220 is directly fixed to the inner side of the pedal 220 by welding or the like, so that the connection bracket 50 can rotate with the pedal 220 as the pedal 220 is stepped on.
Further, as shown in fig. 5, in the initial state, the contact surface 34 is located at the top of the push rod 240, and the distance between the top surface of the push rod 240 and the contact surface 34 is L1. In the initial state, there is a gap between the push rod 240 and the connecting member 30 in the inhalation sensing device 100, so that the inhalation sensing device 100 cannot provide the boost to the push rod 240. The inhalation sensing device 100 provides the boosting force to the push rod 240 only when the connecting member 30 is driven to move downwards by the connecting bracket 50 after the pedal 220 is stepped on, so that the contact surface 34 contacts with the push rod 240.
Further, as shown in fig. 7, in order to enable the suction sensing device 100 provided in the clutch pedal assembly 200 to provide the assisting force. It is necessary to rotate the pedal 220 to make the contact surface 34 of the inhalation sensing device 100 contact with the push rod 240, so as to apply the pushing force generated by the compression spring 40 of the inhalation sensing device 100 to the push rod 240.
As shown in fig. 7, when the pedal 220 rotates by an angle α 1 from the initial state, the pedal 220 drives the connecting member 30 to move downward and makes the contact surface 34 of the connecting member 30 abut against the top surface of the push rod 240. The distance L3 by which the link 30 moves downward in the axial direction of the compression spring 40 at this time is equal to the sum of the distance L2 by which the push rod 240 moves upward in the axial direction of the compression spring 40 by the rotation of the pedal 220 and the distance L1 between the top surface of the push rod 240 and the contact surface 34. That is, when the pedal 220 rotates by an angle α 1 that satisfies L3 ═ L1+ L2, the contact surface 34 of the inhalation sensing device 100 contacts the top surface of the push rod 240, and the inhalation sensing device 100 starts to provide assistance to the push rod 240 to generate inhalation sensing.
When the pedal 220 starts to rotate to an angle α 1 from the initial state, the push rod 240 is moved by the pedal 220 in the direction of the clutch master cylinder 230 and also moved upward by a distance L2 along the axial direction of the spring seat 20 in the suction sensing device 100. Meanwhile, the pedal 220 rotates to drive the connecting bracket 50 of the inhalation sensing device 100 to rotate along the connecting arc 312, and the protrusion 51 of the connecting bracket 50 also rotates around the second rotating shaft 250 by an angle α 1. At this time, as shown in fig. 7, support block 31 of link 30 is moved downward by distance L3 in the axial direction of spring holder 20. Therefore, when the pedal 220 rotates by α 1, the contact surface 34 of the connecting member 30 of the inhalation sensing device 100 abuts against the push rod 240, thereby starting the inhalation sensing device 100 to provide the boost to the push rod 240. At this time, the thrust generated by the compression of the compression spring 40 in the suction sensing device 100 is transmitted to the contact surface 34 by the connecting member 30, and finally acts on the push rod 240, so that the push rod 240 forms a thrust toward the clutch pump assembly 230. The inhalation feeling is generated by the urging force of the compression spring 40 in the inhalation feeling device 100, so that the pedal 220 is more laborsaving to step on.
In the inhalation sensing device 100 provided by the present invention, the size of the rotation angle α 1 can be adjusted by adjusting the distance L1 when the inhalation sensing device 100 is installed or the arc shape of the connecting arc surface 312. By adjusting the rotation α 1, the length of the stroke of the inhalation feeling device 100 can be adjusted during the whole stepping stroke of the pedal 220. In the inhalation-sensitive device 100, different types of compression springs 40 can be selected and adapted to obtain the pre-pressure of the compression spring 40, so that the inhalation-sensitive device 100 can be adjusted to provide inhalation-sensitive feeling, i.e., the assisting force provided by the inhalation-sensitive device 100 to the push rod 240.
Further, in order to ensure that the suction sensor device 100 is in a state capable of assisting power in the clutch pedal assembly 200, the compression spring 40 in the suction sensor device 100 is prevented from being compressed and locked so as not to work normally. It is necessary to ensure that the compression spring 40 is not compressed to the limit when the pedal 220 is depressed to the limit position of the bottom. Therefore, when the pedal 220 is rotated to the bottom limit position by an angle α 2, the distance H1 that the push rod 240 is moved upward along the axial direction of the compression spring 40 by the rotation of the pedal 220 should be less than the sum of the height H2 when the compression spring 40 is compressed to the limit state and the distance L3 that the link 30 is moved downward when the pedal 220 is rotated by an angle α 1. That is, when the pedal 220 is rotated to the limit angle α 2, H1 < H2+ L3 should be satisfied, so as to ensure that the compression spring 40 of the inhalation device 100 will not be compressed and locked, and will operate normally.
The working process of the clutch pedal assembly 200 provided by the invention (as shown in fig. 7) is as follows:
in the initial state, there is a gap L1 between the contact surface 34 of the adaptor block 333 and the push rod 240 in the inhalation sensing device 100, and the inhalation sensing device 100 does not provide the assisting force to the push rod 240.
In the ready state of the inhalation sensor device 100, when the pedal 220 is rotated to an angle α 1 from the initial state, the contact surface 34 of the inhalation sensor device 100 gradually approaches the push rod 240 by the rotation of the pedal 222 and finally abuts against the push rod 240.
When the pedal 220 is turned from α 1 to α 2, which is the limit, in the operating state of the suction sensing device 100, the contact surface 34 of the suction sensing device 100 is always in contact with the push rod 240, and provides the push rod 240 with a thrust force toward the clutch master cylinder 230, thereby generating a suction sense.
According to the clutch pedal assembly 200 provided by the invention, the suction device 100 is additionally arranged, so that a pushing force can be provided for the push rod 240 when the pedal 220 is stepped, the suction feeling of the clutch pedal assembly 200 is improved, the Y-direction limit of the pedal 220 is provided through the connecting support 50 in the suction device 100, the Y-direction play of the pedal 220 is reduced, and the stepping comfort and experience feeling of the pedal 220 are improved.
The invention also provides an automobile comprising the clutch pedal assembly 200. According to the automobile provided by the invention, the inhalation device 100 is arranged in the clutch pedal assembly 200, so that inhalation can be generated in the process of stepping on the pedal 220, and the comfort and experience of an automobile driver are improved.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
