Description

Technical Field

[0001] This application belongs to the technical field of vehicles, and specifically relates to a parking brake handle for vehicle use. Background Art

[0002] After an existing vehicle stops at a parking position, to prevent the vehicle from sliding by itself after parking, the vehicle usually uses a parking brake handle to achieve parking braking. The parking brake handle is connected to the brake caliper of the rear wheel through a wire rope or a connecting rod. The driver pulls up the parking brake handle to make the brake caliper press against the brake pads to keep the vehicle in a parking braking state. The parking brake handle is set beside the driver's seat for the driver to pull up easily. However, after the parking brake is achieved by pulling up the parking brake handle, the parking brake handle will protrude beyond the seat plane. When the driver wants to lie flat on the driver's seat and the co-driver's seat to rest, the parking brake handle will prevent the driver from lying flat.

[0003] To solve the above technical problem that the parking brake handle prevents the driver from lying flat, the authorized announcement number CN216232203U discloses a parking handle assembly and a vehicle having the same. In the case where the vehicle maintains the parking braking state, the parking brake handle can be laid flat. Specifically, a fixed support is provided on the vehicle. The parking brake handle is divided into a handle rotatably connected to the fixed support, a fitting, and a connecting plate rotatably connected to the fixed support. An unlocking switch is also provided on the handle. The fitting is movably arranged on the connecting plate, and the unlocking switch drives the fitting to separate from the handle. When the vehicle is in the parking braking state, the fitting is driven to separate from the handle by the unlocking switch, and the handle rotates to achieve the handle being laid flat. The fitting is located above the fixed support, the unlocking switch is arranged above the fitting, and the unlocking part also has a pressing part that protrudes from the handle surface and has a moving space on the handle surface. However, when the above handle rotates and adjusts to be laid flat, the protruding unlocking part still protrudes beyond the seat plane after the handle is laid flat, preventing the driver from lying flat. The settings of the unlocking switch and the fitting increase the overall height of the parking brake handle, further preventing the driver from lying flat on the driver's and co-driver's seats to rest. In addition, because the unlocking switch is arranged above the fixed support, it is at a long distance from the part held by the operator. After the operator keeps the vehicle in the parking braking state, the operator needs to release the handle and then look for the unlocking switch to operate. To achieve the handle being laid flat requires the cooperation of both hands, one hand to unlock and the other hand to press the handle to rotate to achieve being laid flat. This requires the driver to adjust the sitting posture to face the parking brake handle. The space for people to move freely in the vehicle is limited, and the driver also needs to rotate the body significantly to achieve the operation of laying flat the handle. Therefore, the above technical solution is difficult to operate and cannot meet the driver's need to lie flat on the driver's and co-driver's seats. Moreover, the parking brake handle modified by using this technical solution has an increased height and occupies more space in the vehicle. Summary of the Utility Model

[0004] The present application provides a parking brake handle for a vehicle to solve the technical problems that the unlocking switch and its cooperating parts of the existing parking brake handle are arranged above the fixed support, it is difficult for a person to operate the unlocking switch to flatten the parking brake handle after pulling up the parking brake handle, there is still a part higher than the seat plane after the parking brake handle is flattened, and the height of the parking brake handle is too high, occupying a large amount of interior space of the vehicle.

[0005] The technical solution adopted in the present application is as follows:

[0006] A parking brake handle for a vehicle, the parking brake handle includes a locking mechanism fixedly connected to the vehicle body, a wiring structure rotatable relative to the locking mechanism, and an operating structure connected to the wiring structure. The wiring structure is connected to a brake wire, and the operating structure can drive the wiring structure to rotate to lock or unlock with the locking mechanism to realize parking braking or releasing parking braking of the vehicle. A seat for a person to sit on is provided on one side of the parking brake handle of the vehicle. The operating structure includes a connecting part rotatable relative to the locking mechanism and a holding part extending outward from the connecting part for an operator to hold. The operating structure further includes a movable part. The movable part is arranged between the holding part and the connecting part, and the movable part is located below the holding part. The movable part can move to have a limiting state in which it is in limiting cooperation with the wiring structure and a separating state in which it is separated from the wiring structure. In the separating state, the operating structure can be rotated to a position where its top end is parallel to or lower than the sitting surface of the seat for a person to sit on.

[0007] A parking brake handle for a vehicle in the present application further includes the following additional technical features:

[0008] The movable part includes a limiting part that can be in limiting cooperation with the wiring structure and an operating part extending from the limiting part to the holding part. The operating part can move to drive the limiting part to switch between the limiting state and the separating state with the wiring structure.

[0009] The operating structure has a first direction of the connection line between the holding part and the connecting part, and the moving direction of the operating part is the same as the first direction; or, the holding part rotates around a first axis, and the moving direction of the operating part is the same as the first axis.

[0010] One of the limiting part and the wiring structure is provided with a limiting protrusion, and the other of the two is provided with a limiting groove that is in snap-fit with the limiting protrusion, and the limiting groove opens towards the side of the limiting protrusion.

[0011] The operating part and the limiting part are integrally formed, and at least part of the operating part exposes the outer side wall of the holding part; or, the operating part is an operating piece that is formed separately from the limiting part, and at least part of the operating piece exposes the outer side wall of the holding part.

[0012] The operating part is an operating member integrally formed with the limiting part. The operating member includes a rotating shaft rotatably connected to the holding part and a driving convex part connected to the rotating shaft. The movable member further includes a connecting rod extending from the limiting part to the operating member. The connecting rod is provided with a driven hole, and the driving convex part abuts against the driven hole to drive the connecting rod to reciprocate.

[0013] The connecting rod is further provided with an avoidance opening for avoiding the rotating shaft.

[0014] The movable member is connected with an elastic reset member. In the separated state, the elastic reset member is compressed and drives the movable member to abut against the outer contour of the wiring structure.

[0015] The operating structure is further provided with a guiding member, and the movable member moves along the guiding member.

[0016] The guiding member includes a guiding shaft provided on the holding part, and the movable member has a guiding shaft hole for cooperating with the guiding shaft.

[0017] Due to the adoption of the above technical solutions, the beneficial effects obtained by this application are as follows:

[0018] 1. By setting the operating structure in this application, the operating structure has a holding part for the operator to facilitate operation. The operating structure further includes a movable member, which is arranged between the holding part and the connecting part, and the movable member is located below the holding part. After the operator lifts the holding part to complete the vehicle parking brake, the movable member can be directly operated to flatten the parking brake handle, avoiding the situation that the operator needs to release the holding part and then search for the movable member, thus improving the operation efficiency. At the same time, when the operating structure rotates to a position where its top end is parallel to or lower than the seat sitting surface, the movable member is located below the holding part, ensuring that the movable member does not protrude from the sitting surface, and the person can lie flat on the seat. Moreover, since the movable member is located below the holding part, the movable member is arranged by using the space below the holding part, which can keep the vertical height of the parking brake handle unchanged, realize a compact layout of the parking brake handle, occupy a small space in the vehicle, and improve the utilization rate of the vehicle interior space. The movable member can move to have a limiting state of limiting cooperation with the wiring structure and a separated state of separating from the wiring structure. In the connected state, when the operator lifts the holding part, the movable member drives the wiring structure to rotate and lock with the locking mechanism to realize vehicle braking. When the movable member is in the separated state and the wiring structure is locked by the locking mechanism, the operating structure can rotate to a position where its top end is parallel to or lower than the seat sitting surface for the person to sit so that the person can lie flat on the seat.

[0019] 2. As a preferred embodiment of this application, the movable member has an operating part extending from the limiting part to the holding part, and the distance between the holding part and the operating part is shortened. After the operator lifts the holding part to realize the vehicle parking brake, the operator can directly operate the operating part, and the operating part drives the limiting part to switch from the limiting state to the separated state. Then the operator can hold the holding part and rotate it to realize that the operating structure rotates to a position where its top end is parallel to or lower than the seat sitting surface for the person to sit, improving the operation efficiency.

[0020] Further, the moving direction of the operating part is the same as the first direction. When the operator holds the holding part and operates the operating part to move along the first direction, the influence on the holding part and the connecting part is small, which optimizes the force on the limiting part and the operating part. Or the moving direction of the operating part is the same as the first axis. When the operator holds the holding part, the operating part can be moved along the first axis direction by pressing or pulling, so as to drive the limiting part to separate from or cooperate with the wiring structure, which is more convenient to drive the operating part to move and further improves the operating efficiency.

[0021] Furthermore, by setting that the wiring structure and the limiting part are matched through the limiting protrusion and the limiting groove, the limiting groove has an opening facing one side of the limiting protrusion, and the cooperation between the limiting protrusion and the limiting groove is more convenient, and it is easier for the limiting part to be limited and cooperate with or separate from the wiring structure, which optimizes the process of limiting and cooperating or separating the limiting part and the wiring structure and improves the user's operating experience.

[0022] 3. As a preferred embodiment of the present application, by setting the operating part and the limiting part to be integrally formed, the overall strength of the moving part is improved, and a compact setting of the moving part is realized. When the operator operates the operating part, the response of the operating part to drive the limiting part to move is more rapid. By setting the operating part as a split-shaped operating piece, the material waste during production is reduced, which is convenient for later replacement and maintenance. At least part of the operating part exposes the outer side wall of the holding part; or an operating piece is provided, and at least part of the operating piece exposes the outer side wall of the holding part, so that the operator can more directly identify the position of the operating piece, which is convenient for the operator to operate and improves the operating efficiency. At least part of the operating piece or the operating part exposes the outer side wall of the holding part, which further ensures that the operating piece does not protrude from the seat riding surface after the operating structure is laid flat, and at the same time, when the operator holds the holding part, the operator can more conveniently drive the operating piece or the operating part.

[0023] Further, by setting the operating part as a split-shaped operating piece, the operating piece is rotatably connected to the holding part, and the driving convex part is driven to abut against the driven hole through the rotation of the operating piece to realize the reciprocating movement of the connecting rod. The rotation range of the operating piece is small. When the operator rotates the operating piece, the movement amplitude of the operator is reduced, which is convenient for personnel to operate. At the same time, the connection of each component during the rotation of the operating piece is closer, which helps to realize a compact design. The rotation mechanical structure of the operating piece is simple, with high reliability and simple and convenient operation.

[0024] Furthermore, the connecting rod is provided with an avoidance opening for avoiding the rotating shaft, and the connecting rod moves in the avoidance opening, which reduces the hard contact between the rotating shaft and the connecting rod, improves the stability of the operating piece, extends the service life of the rotating shaft and the connecting rod, and reduces the maintenance cost.

[0025] 4. As a preferred embodiment of the present application, the movable member is connected with an elastic reset member. When the operating structure rotates, the elastic reset member drives the movable member to abut against the outer contour of the wiring structure. At the position where the wiring structure is in limit cooperation with the movable member, the elastic reset member can drive the movable member to be in limit cooperation with the wiring structure, facilitating the reset of the movable member and optimizing the operation process of the parking brake handle.

[0026] 5. As a preferred embodiment of the present application, by providing a guiding member, the movable member moves along the guiding member, facilitating the movement of the movable member, reducing the movement wear of the movable member, and improving the smoothness of the movement of the movable member.

[0027] Furthermore, by providing a guiding shaft and a guiding shaft hole that cooperates with the guiding shaft, the movement accuracy of the movable member is further improved. The guiding shaft can move within the guiding shaft hole, and the guiding shaft can move into the shaft hole, thereby reducing the internal space provided for the movement of the guiding member and the movable member and achieving a compact layout.

[0038] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0039] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below. It should be noted that, without conflict, the embodiments of the present application and the features in each embodiment may be combined with each other.

[0040] As Figure 1 、 Figure 2 shown, a parking brake handle 1 for a vehicle, the parking brake handle 1 includes a locking mechanism 2 fixedly connected to the vehicle body, a wiring structure 3 rotatable relative to the locking mechanism 2, and an operating structure 4 connected to the wiring structure 3. The wiring structure 3 is connected to a brake wire. The operating structure 4 can drive the wiring structure 3 to rotate to lock or unlock with the locking mechanism 2 to realize parking braking or releasing parking braking of the vehicle. A seat for a person to sit on is provided on one side of the parking brake handle 1 of the vehicle. The operating structure 4 includes a connecting part 41 rotatable relative to the locking mechanism 2 and a holding part 42 extending outward from the connecting part 41 for an operator to hold. The operating structure 4 further includes a movable part 43. The movable part 43 is arranged between the holding part 42 and the connecting part 41, and the movable part 43 is located below the holding part 42. The movable part 43 can move to have a limiting state of being in limiting cooperation with the wiring structure 3 and a separating state of being separated from the wiring structure 3. In the separating state, the operating structure 4 can be rotated to a position where its top end is parallel to or lower than the sitting surface of the seat for a person to sit on.

[0041] By providing an operating structure 4, the operating structure 4 has a holding portion 42 for the operator to facilitate operation. The operating structure 4 further includes a movable member 43, the movable member 43 is disposed between the holding portion 42 and the connecting portion 41, and the movable member 43 is located below the holding portion 42. After the operator lifts the holding portion 42 to complete the vehicle parking brake, the movable member 43 can be directly operated to flatten the parking brake handle 1, avoiding the situation where the operator needs to release the holding portion 42 and then search for the movable member 43, thereby improving the operation efficiency. At the same time, when the operating structure 4 rotates to a position where its top end is parallel to or lower than the seat sitting surface, the movable member 43 is located below the holding portion 42, ensuring that the movable member 43 does not protrude from the sitting surface, and the person can lie flat on the seat. Moreover, since the movable member 43 is located below the holding portion 42, the space below the holding portion 42 is utilized to arrange the movable member 43, which can keep the vertical height of the parking brake handle 1 unchanged, realize a compact layout of the parking brake handle 1, occupy less space in the vehicle, and improve the utilization rate of the vehicle interior space. The movable member 43 is movable to have a limiting state in which it is in limiting cooperation with the wiring structure 3 and a separated state in which it is separated from the wiring structure 3. In the connected state, when the operator lifts the holding portion 42, the movable member 43 drives the wiring structure 3 to rotate and lock with the locking mechanism 2 to achieve vehicle braking. When the movable member 43 is in the separated state, the wiring structure 3 is locked by the locking mechanism 2, and the operating structure 4 can be rotated to a position where its top end is parallel to or lower than the sitting surface of the seat for the person to sit on so that the person can lie flat on the seat.

[0042] In the present application, the wiring structure 3 and the operating structure 4 are rotatably connected to the locking mechanism 2 through a rotating shaft 23. It is clear to those skilled in the art that the rotation of the wiring structure 3 and the operating structure 4 relative to the locking mechanism 2 can also be achieved by rotatably arranging the wiring structure 3 and the operating structure 4 on the vehicle body, fixing the locking mechanism 2 on the vehicle body or providing a fixed support on the vehicle body, and rotatably connecting the wiring structure 3, the operating structure 4 and the fixed support, and arranging the locking mechanism 2 on the fixed support and other ways.

[0043] In the present application, the structural form of the wiring structure 3 is not limited, and it can be single-layer or double-layer. In the single-layer case, the wiring structure 3, the operating structure 4, and the locking mechanism 2 are arranged in sequence along the rotating shaft 23. Such as Figure 1 、 Figure 3As shown, when the wiring structure 3 has a double layer, the locking mechanism 2 and the operating structure 4 are placed between the two layers of the wiring structure 3, improving the rotational stability of the wiring structure 3 and the locking effect of the locking mechanism 2. At the same time, the wiring structure 3 has a double layer, increasing the parts that are in limit cooperation with the limiting part 431, enabling better limit cooperation with the limiting part 431, improving the stability of the cooperation, and also providing more parts that can connect the brake wire, offering multiple choices for the connection position of the brake wire. Further, the operating structure 4 has a movable cavity. The operating structure 4 has two oppositely arranged side plates, and the upper edges of the two side plates are connected by an arc plate. The two side plates and the arc plate form a movable cavity for the movable part 43 to move, making it more convenient for the movable part 43 to move. Even further, the locking structure 2 is arranged in the movable cavity, and the operating structure 4 is rotatably connected to the locking structure 2, improving the rotational stability of the operating structure 4, further reducing the space occupied by the parking brake handle 1, and achieving a compact design. Those skilled in the art can know that the movable cavity of the operating structure 4 can also be formed by processes such as cutting and casting during production.

[0044] As a preferred embodiment of the present application, as Figure 1 、 Figure 2 shown, the movable part 43 includes a limiting part 431 that can be in limit cooperation with the wiring structure 3 and an operating part 432 extending from the limiting part 431 to the holding part 42. The operating part 432 can move to drive the limiting part 431 to switch between the limiting state and the separated state with the wiring structure 3. The movable part 43 has an operating part 432 extending from the limiting part 431 to the holding part 42, and the distance between the holding part 42 and the operating part 432 is shortened. After the operator pulls up the holding part 42 to achieve vehicle parking braking, the operator can directly operate the operating part 432, and the operating part 432 drives the limiting part 431 to switch from the limiting state to the separated state. Then the operator can hold the holding part 42 and rotate it, enabling the operating structure 4 to rotate to a position where its top is parallel to or lower than the seating surface for people to sit, improving the operation efficiency.

[0045] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 shown, the moving direction of the movable part 43 can be any one of the following embodiments:

[0046] Embodiment 1: The operating structure 4 has a first direction along the line connecting the holding part 42 and the connecting part 41. Preferably, as Figure 3 shown, the line connecting the holding part 42 and the connecting part 41 points to the horizontal direction, and the moving direction of the operating part 432 is the same as the first direction. As Figure 1 、 Figure 2 shown, the operating part 432 moves in the left - right direction in the figure, having little influence on the holding part 42 and the connecting part 41, and optimizing the force on the limiting part 431 and the operating part 432.

[0047] Embodiment 2: The holding part 42 rotates around the first axis. Preferably, as Figure 1 shown, the holding part 42 rotates around the rotation axis 23, and the moving direction of the operating part 432 is the same as the first axis, that is, the same as the axis of the rotation axis 23. When the operator holds the holding part 42 by hand, the operating part 432 can be moved along the first axis direction by pressing or pulling, so as to drive the limiting part 431 to separate from or cooperate with the wiring structure 3, which is more convenient for driving the movement of the operating part 432 and further improves the operation efficiency.

[0048] In Embodiment 1 and Embodiment 2, as Figure 2 , Figure 3 shown, the cooperation mode between the limiting part 431 and the wiring structure 3 can be any one of the following specific examples:

[0049] Specific Example 1: As a preference, as Figure 3 shown, the limiting part 431 is provided with a limiting protrusion 4311, and the wiring structure 3 is provided with a limiting groove 31 that cooperates with the limiting protrusion 4311. The limiting groove 31 has an opening on the side facing the limiting protrusion 4311.

[0050] Specific Example 2: The wiring structure 3 is provided with a limiting protrusion 4311, and the limiting part 431 is provided with a limiting groove 31 that cooperates with the limiting protrusion 4311. The limiting groove 31 has an opening on the side facing the limiting protrusion 4311.

[0051] By setting the wiring structure 3 and the limiting part 431 to cooperate through the limiting protrusion 4311 and the limiting groove 31, and the limiting groove 31 has an opening on the side facing the limiting protrusion 4311, the cooperation between the limiting protrusion 4311 and the limiting groove 31 is more convenient, and it is easier for the limiting part 431 to be limited and cooperate with or separated from the wiring structure 3, optimizing the process of limiting and cooperating or separating between the limiting part 431 and the wiring structure 3, and improving the operation experience of the user.

[0052] In this embodiment, the setting mode of the operating part 432 and the limiting part 431 can be any one of the following embodiments:

[0053] Embodiment 3: The operating part 432 and the limiting part 431 are integrally formed. By setting the operating part 432 and the limiting part 431 to be integrally formed, the strength of the movable part 43 as a whole is improved, and a compact setting of the movable part 43 is realized. When the operator operates the operating part 432, the operating part 432 drives the limiting part 431 to move more quickly. Moreover, at least a part of the operating part 432 exposes the outer side wall 421 of the holding part 42. The operator holds the part of the operating part 432 that exposes the outer side wall 421 of the holding part 42, and the operating part 432 then drives the limiting part 431 to move.

[0054] Preferably, the operating part 432 is a rod member that exposes the outer wall 421 of the holding part 42. When the rod member moves along the Figure 2 and Figure 3 horizontal direction, the holding part 42 has a moving groove for avoiding the moving path of the rod member. The operator drives the rod member to move, and then drives the limiting part 431 to move.

[0055] Embodiment 4: As shown in Figure 1 and Figure 3 , the operating part 432 is an operating member 433 integrally formed with the limiting part 431. By providing the operating member 433 integrally formed with the limiting part 431, material waste during production is reduced, and later replacement and maintenance are facilitated. At least part of the operating member 433 exposes the outer wall 421 of the holding part 42.

[0056] At least part of the operating part 432 exposes the outer wall 421 of the holding part 42; or an operating member 433 is provided, and at least part of the operating member 433 exposes the outer wall 421 of the holding part 42. The operator can more directly identify the position of the operating member 433, which is convenient for the operator to operate and improves the operation efficiency. At least part of the operating member 433 or the operating part 432 exposes the outer wall 421 of the holding part 42, further ensuring that the operating member 433 does not protrude from the seat riding surface after the operating structure 4 is placed flat, and at the same time, when the holding part 42 is held by hand, the operator can more conveniently drive the operating member 433 or the operating part 432.

[0057] In Embodiment 4, the setting manner of the operating member 433 can be any one of the following specific examples:

[0058] Specific Example 3: Preferably, as shown in Figure 1 and Figure 3As shown in the figure, the operating member 433 includes a rotating shaft 4331 rotatably connected to the holding portion 42 and a driving convex portion 4332 connected to the rotating shaft 4331. The movable member 43 further includes a connecting rod 434 extending from the self-limiting portion 431 to the operating member 433. The connecting rod 434 is provided with a driven hole 4341, and the driving convex portion 4332 abuts against the driven hole 4341 to drive the connecting rod 434 to reciprocate. By setting the operating portion 432 as a separately formed operating member 433, the operating member 433 is rotatably connected to the holding portion 42. The rotation of the operating member 433 drives the driving convex portion 4332 to abut against the driven hole 4341 to realize the reciprocating movement of the connecting rod 434. The rotation range of motion of the operating member 433 is small. When the operator rotates the operating member 433, the movement amplitude of the operator is reduced, which is convenient for personnel operation. At the same time, when the operating member 433 rotates, the connection of each component is tighter, which helps to achieve a compact design. The rotation mechanical structure of the operating member 433 is simple, with high reliability and simple and convenient operation. Further, the rotating shaft 4331 passes through the connecting rod 434, and the connecting rod 434 is provided with an avoidance opening 4342 for avoiding the rotating shaft 4331. The connecting rod 434 is provided with an avoidance opening 4342 for avoiding the rotating shaft 4331, and the connecting rod 434 moves within the avoidance opening 4342, reducing the hard contact between the rotating shaft 4331 and the connecting rod 434, improving the stability of the operating member 433, extending the service life of the rotating shaft 4331 and the connecting rod 434, and reducing the maintenance cost.

[0059] Preferably, the operating member 433 is provided with a reset elastic member. The reset elastic member is a torsion spring. The torsion spring is arranged on the rotating shaft 4331. One end of the torsion spring is connected to the driving convex portion 4332, and one end is fixedly connected to the holding portion 42. The rotation of the rotating shaft 4331 drives the limiting portion 431 to separate from the wiring structure 3. At the same time, the torsion spring deforms, and the operating structure 4 rotates. The torsion spring drives the limiting portion 431 to abut against the outer contour of the wiring structure 3. At the limiting cooperation position between the limiting portion 431 and the wiring structure 3, the torsion spring drives the limiting portion 431 to be in limiting cooperation with the wiring structure 3, optimizing the process of re-limiting cooperation between the limiting portion 431 and the wiring structure 3.

[0060] Specific Example 4: The operating member 433 includes a rotating shaft 4331 rotatably connected to the holding portion 42. The rotating shaft 4331 has a thread. The movable member 43 further includes a connecting rod 434 extending from the self-limiting portion 431 to the operating member 433. The connecting rod 434 is provided with a threaded hole that is threadedly engaged with the rotating shaft 4331. The rotation of the rotating shaft 4331 drives the connecting rod 434 to move in the same direction as the first axis around which the holding is located.

[0061] As a preferred embodiment in the present application, although not illustrated in this embodiment, the movable member 43 is connected with an elastic reset member. In the separated state, the elastic reset member is compressed and drives the movable member 43 to abut against the outer contour of the wiring structure 3. Preferably, one end of the elastic reset member is connected with the movable member 43, and the other end is fixed to the holding portion 42. At the position where the wiring structure 3 is in limit cooperation with the movable member 43, the elastic reset member can drive the movable member 43 to be in limit cooperation with the wiring structure 3, facilitating the reset of the movable member 43 and optimizing the operation process of the parking brake handle 1.

[0062] As a preferred embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 shown, the operating structure 4 is provided with a guiding member 44, and the movable member 43 moves along the guiding member 44. By providing the guiding member 44, the movable member 43 moves along the guiding member 44, facilitating the movement of the movable member 43, reducing the movement wear of the movable member 43, and improving the smoothness of the movement of the movable member 43.

[0063] In this embodiment, preferably, as Figure 3 shown, the guiding member 44 includes a guiding shaft 441 provided on the holding portion 42, and the movable member 43 has a guiding shaft hole 435 that cooperates with the guiding shaft 441.

[0064] By providing the guiding shaft 441 and the guiding shaft hole 435 that cooperates with the guiding shaft 441, the movement precision of the movable member 43 is further improved. The guiding shaft 441 can move within the guiding shaft hole 435, and the guiding shaft 441 can move into the guiding shaft hole 435, thereby reducing the internal space provided for the movement of the guiding member 44 and the movable member 43 and achieving a compact layout.

[0065] Those skilled in the art can clearly understand that the setting manner of the guiding member 44 is not limited to the above-mentioned setting of the guiding shaft 441 on the holding portion. It is also possible to set a guiding shaft hole 435 on the holding portion, and the movable member 43 has a guiding shaft. It can also be to provide a protrusion on the holding portion 42, and the movable member 43 has a groove that cooperates with the protrusion, or to provide a groove on the holding portion 42, and the movable member 43 has a protrusion, etc.

[0066] As a preferred embodiment of the present application, as Figure 1 [[ID=2S]], Figure 2 , Figure 3 shown, the locking mechanism 2 is provided at the rear side of the wiring structure 3 along the axial direction of the vehicle, Figure 3 the right side in. The locking mechanism 2 includes a ratchet section 22 fixedly connected to the vehicle body and a ratchet pawl 21 provided on the right side of the wiring structure 3 to lock or unlock the wiring structure 3 in cooperation with the ratchet section 22. The ratchet pawl 21 is rotatably connected to the wiring structure 3.

[0067] Under this embodiment, the driving of the pawl 21 can be any one of the following embodiments:

[0068] Embodiment 5: As Figure 1 , Figure 2 shown, the operating structure 4 is further provided with a connecting rod 45. The connecting rod 45 has a connecting end located in front of the pawl 21. The connecting end has a bent portion 451. The operating structure 4 is provided with a limiting protrusion 46, and the bent portion 451 is connected to the limiting protrusion 46. Preferably, the connecting rod 45 is further provided with a pressing portion 452 protruding from the holding portion 42. The pressing portion 452 is connected with an elastic component 453. By pressing the pressing portion 452, the connecting end drives the pawl 21 to rotate, and the elastic component 453 drives the connecting rod 45 to reset to the initial position, and the limiting protrusion 46 abuts against the bent portion 451 to stop the movement of the connecting rod 45.

[0069] By pressing the pressing portion 452 to drive the connecting rod 45 to abut against the pawl 21, the wiring structure 3 is unlocked. After the operator presses the pressing portion 452, the direct driving of the pawl 21 for unlocking has high efficiency, and the failure rate of unlocking the wiring structure 3 during use is reduced.

[0070] Embodiment 6: The pawl 21 has an operating portion exposed to the right side of the edge of the wiring structure 3 in the horizontal direction in Figure 3 , or an operating lever is arranged on the right side of the pawl 21 to drive the pawl 21 to rotate.

[0071] As a preferred embodiment of the present application, as Figure 4 shown, the wiring structure 3 is further provided with a guiding section 32. The brake wire is fixedly connected to the wiring structure 3 through the guiding section 32. Preferably, the guiding section 32 is arranged in an arc shape and has a front side and / or a rear side facing the vehicle axial direction. Preferably, as Figure 4 shown, the guiding section 32 has a wiring port 321 facing the right side shown in the figure.

[0072] By providing the guiding section 32, the movement of the brake wire can be effectively guided. When the operating structure 4 rotates to drive the wiring structure 3 to rotate, the brake wire moves along the guiding section 32, avoiding the winding of the brake wire and improving the stability of the vehicle parking brake. At the same time, the brake wire is uniformly stressed along the guiding section 32, effectively avoiding the wear of the brake wire and improving the service life of the brake wire. By providing the wiring port 321 facing the front side and / or the rear side of the vehicle axial direction, the parking brake handle 1 can be applied to models with front or rear brake wires, expanding the applicable vehicle models of the parking brake handle 1.
