Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

[0031] Reference below Figure 1-Figure 8 A parking mechanism 100 according to an embodiment of the present invention is described.

[0032] like Figure 1-Figure 4 As shown, the parking mechanism 100 according to the embodiment of the present utility model comprises: a parking cam 10 , a parking ratchet 20 and a pawl assembly 30 .

[0033] The parking cam 10 and the parking ratchet 20 are respectively rotatably installed in the housing of the reducer, and the parking ratchet 20 is dynamically connected to the reducer. The pawl assembly 30 includes a first connecting rod 31 and a pawl 32. The pawl 32 is rotatably connected to the first connecting rod 31. A first elastic member 33 is provided between the pawl 32 and the first connecting rod 31. The first elastic member 33 is used to apply an elastic force to the pawl 32 to rotate around a first direction. The parking cam 10 is suitable for pushing the first connecting rod 31 to drive the pawl 32 to rotate along the second direction to press against the parking ratchet 20.

[0034] Therefore, when the pawl 32 contacts the tooth top of the parking ratchet 20, the pawl 32 will be forced to rotate to prevent the motor from stalling, and the pawl 32 can be reset by the elastic force of the first elastic member 33 after being forced to rotate, thereby achieving the engagement of the pawl 32 with the parking ratchet 20 to reduce the risk of engagement.

[0035] For example Figure 1-Figure 4 As shown, the parking mechanism 100 includes a driving member, a parking cam 10 , a parking ratchet 20 and a pawl assembly 30 .

[0036] The driving member may be a driving motor 40 , the parking cam 10 is fixedly sleeved on a transmission shaft 41 of the driving motor 40 , the pawl assembly 30 is rotatably mounted in a housing of the reducer, and the parking ratchet 20 is dynamically connected to an output shaft of the reducer.

[0037] Among them, the outer peripheral wall of the parking cam 10 includes a contour surface of a maximum stroke and a contour surface of a minimum stroke. The driving motor 40 is suitable for driving the transmission shaft 41 to drive the parking cam 10 to rotate to the contour surface of the maximum stroke and contact with the pawl assembly 30 to push the pawl assembly 30 to engage with the parking ratchet 20 to achieve the parking state, or the driving motor 40 is suitable for driving the transmission shaft 41 to drive the parking cam 10 to rotate to the contour surface of the minimum stroke and contact with the pawl assembly 30 to release the thrust on the pawl assembly 30, thereby separating the pawl assembly 30 from the parking ratchet 20 to release the parking state.

[0038] Furthermore, if Figure 1-Figure 4 As shown, the pawl assembly 30 includes a first link 31 and a pawl 32 .

[0039] The pawl 32 is rotatably connected to the first connecting rod 31, and a first elastic member 33 is provided between the pawl 32 and the first connecting rod 31. The first elastic member 33 is used to apply an elastic force to the pawl 32 to rotate around a first direction. The parking cam 10 is suitable for pushing the first connecting rod 31 to drive the pawl 32 to rotate along the second direction to press against the parking ratchet 20, wherein the first direction and the second direction are opposite.

[0040] For example, the first direction is a clockwise direction and the second direction is a counterclockwise direction, or the first direction is a counterclockwise direction and the second direction is a clockwise direction, which is not limited here.

[0041] For example, the first direction is counterclockwise, and the second direction is clockwise.

[0042] When working, the power unit first drives the parking cam 10 to rotate through the transmission shaft 41 by the driving motor 40. During the movement, the parking cam 10 pushes the first connecting rod 31 to drive the pawl 32 to rotate clockwise. At this time, the first elastic member 33 deforms and the elastic potential energy increases. The pawl 32 is stationary relative to the first connecting rod 31. As the stroke of the parking cam 10 increases, the parking pawl 32 begins to mesh with the parking ratchet 20. If the parking ratchet 20 is in a position that can fully mesh with the parking pawl 32, the driving motor 40 stops rotating after the parking cam 10 moves to the maximum stroke. At this time, the line connecting the contact point between the parking cam 10 and the first connecting rod 31 and the center of the parking cam 10 is perpendicular to the first connecting rod 31, ensuring that the force transmitted from the parking ratchet 20 to the first connecting rod 31 will not push the parking cam 10 to rotate, thereby ensuring the parking stability of the parking mechanism 100.

[0043] If the parking pawl 32 contacts the tooth surface or tooth top of the parking ratchet 20 due to the random rotation of the parking ratchet 20 during parking, a force F is formed at the contact point along the normal direction of the tooth surface of the parking ratchet 20, and the component force of F pushes the parking pawl 32 to overcome the elastic force of the first elastic member 33 and rotate to avoid the rotation of the parking ratchet 20, so that the parking cam 10 can normally push the first connecting rod 31 to move to the maximum stroke of the parking cam 10. At this time, the parking pawl 32 enters the tooth groove of the parking ratchet 20 along the tooth wall of the parking ratchet 20, and when the parking ratchet 20 moves in the clockwise direction, the parking pawl 32 rotates counterclockwise under the action of the first elastic member 33, so that the parking pawl 32 is fully engaged with the parking ratchet 20, completing the parking brake process.

[0044] The angles of rotation of the parking cam 10 in the above two different parking conditions are the same, so the power-on time of the drive motor 40 is fixed, and there is no need to design other parts or apply additional signals to control the power-on time of the drive motor 40 to control the movement of the parking cam 10. When the parking brake needs to be released, the parking cam 10 continues to rotate, the stroke is reduced, and the first connecting rod 31 rotates in the opposite direction to disengage the pawl 32 from the parking ratchet 20, and the parking brake is released.

[0045] It should be noted that the pawl assembly 30 in the present invention is a split structure including a first connecting rod 31 and a pawl 32. Compared with the pawl 32 of an integrated structure in the prior art, the parking mechanism 100 of the present invention can adjust the position of the pawl 32 through the first elastic member 33 during the application of the parking brake, thereby ensuring the independence of the movement of the drive motor 40, the continuity of the rotation of the parking cam 10 and the reliability of the engagement between the ratchet and the parking pawl 32, thereby preventing the motor from stalling and reducing the risk of engagement.

[0046] According to the parking mechanism 100 of the embodiment of the utility model, its pawl 32 is rotatably connected to the first connecting rod 31. When the pawl 32 contacts the tooth top of the parking ratchet 20, the pawl 32 will be forced to rotate to prevent the motor from stalling, and the first elastic member 33 can apply an elastic force to the pawl 32 to rotate around a first direction, so that the pawl 32 can be reset by using the elastic force of the first elastic member 33 after being forced to rotate, that is, the position of the pawl 32 can be adjusted by the first elastic member 33, thereby achieving the engagement of the pawl 32 with the parking ratchet 20 to reduce the risk of engagement.

[0047] In some embodiments, Figure 1-Figure 4 As shown, the parking mechanism 100 further includes a second link 34 .

[0048] One end of the second link 34 is connected to the pawl 32 , and the other end is slidably connected to the first link 31 .

[0049] Specifically, one end of the second connecting rod 34 is fixedly connected to the pawl 32 by a bolt 50 to enhance the connection stability of the pawl 32 of the second connecting rod 34 and facilitate the disassembly and separation of the two. At the same time, the other end of the second connecting rod 34 is slidably connected to the first connecting rod 31 to limit the maximum rotation angle of the pawl 32 by the movement of the other end of the second connecting rod 34, thereby avoiding excessive rotation of the pawl 32 and breaking the first elastic member 33, thereby enhancing the protection of the first elastic member 33 and facilitating the extension of the service life of the first elastic member 33.

[0050] In some embodiments, Figure 1-Figure 4 As shown, the first connecting rod 31 is connected to the first connecting member 37 , the other end of the second connecting rod 34 is provided with a sliding groove 341 , and the first connecting member 37 is inserted into the sliding groove 341 and slidably cooperates with the sliding groove 341 .

[0051] Therefore, the relative sliding of the second connecting rod 34 and the first connecting rod 31 can be achieved through the cooperation between the first connecting member 37 and the sliding groove 341. For example, the first connecting member 37 can be constructed as a connecting bolt 50. Such a setting method is simpler and helps to reduce costs. Moreover, since the first connecting member 37 is inserted into the sliding groove 341, when the pawl 32 drives the second connecting rod 34 to rotate to the maximum angle, the inner wall of the sliding groove 341 can abut against the first connecting member 37, thereby limiting the maximum rotation angle of the pawl 32, thereby preventing the pawl 32 from rotating excessively and breaking the first elastic member 33, thereby improving the protection of the first elastic member 33 and helping to extend the service life of the first elastic member 33.

[0052] Furthermore, if Figure 8 As shown, the guide groove 341 is configured as a strip groove.

[0053] Therefore, by constructing the sliding groove 341 as a strip groove, when the pawl 32 drives the second connecting rod 34 to rotate, the second connecting rod 34 slides along the extension direction of the strip groove under the limitation of the first connecting member 37, thereby better limiting the maximum rotation angle of the pawl 32.

[0054] In some embodiments, Figure 5 and Figure 7 As shown, the pawl 32 is rotatably connected to the first connecting rod 31 via a rotating shaft 36 , and the first elastic member 33 is elastically connected between the pawl 32 and the rotating shaft 36 .

[0055] For example, Figure 5As shown, the first connecting rod 31 is provided with a first mounting hole 311, and the rotating shaft 36 can be rotatably installed in the first mounting hole 311, thereby, the rotation stability of the pawl 32 and the first connecting rod 31 can be enhanced, and the first elastic member 33 is elastically connected between the pawl 32 and the rotating shaft 36. Since the position of the rotating shaft 36 relative to the first connecting rod 31 remains unchanged, it is equivalent to the first elastic member 33 being elastically connected between the pawl 32 and the first connecting rod 31, and the first elastic member 33 is elastically connected between the pawl 32 and the rotating shaft 36, so as to make full use of the installation space, which is beneficial to improve the space utilization rate, and the layout is simpler.

[0056] In some embodiments, the first elastic member 33 is configured as a first torsion spring, which is sleeved on the rotating shaft 36 , with one end of the first torsion spring connected to the rotating shaft 36 and the other end of the first torsion spring connected to the pawl 32 .

[0057] For example, the first torsion spring is sleeved on the rotating shaft 36 and is located in the first mounting hole 311. In this way, the layout space outside the first mounting hole 311 can be saved, thereby improving space utilization. The first torsion spring is sleeved on the rotating shaft 36 to enhance the structural stability of the first torsion spring.

[0058] In some embodiments, Figure 2-Figure 4 As shown, the parking mechanism 100 further includes a second elastic member 35 .

[0059] The second elastic member 35 is connected between the housing of the reducer and the first connecting rod 31 , and the second elastic member 35 is used to apply an elastic force to the first connecting rod 31 to rotate around a first direction.

[0060] Therefore, when the parking state is released, that is, when the parking cam 10 rotates to the minimum stroke and the corresponding contour surface is opposite to the first connecting rod 31, that is, the first connecting rod 31 is not affected by the force of the parking cam 10 or the force of the parking cam 10 gradually decreases, the second elastic member 35 applies an elastic force to the first connecting rod 31 to rotate around the first direction, so that the first connecting rod 31 drives the pawl 32 to rotate around the first direction and thus separates from the parking ratchet 20 to release the parking state. In this way, the second elastic member 35 can be set up so that when the parking state is released and the first connecting rod 31 is reset, there is no need to set up a separate motor for driving, and the first connecting rod 31 can be reset by only using the elastic force of the second elastic member 35, thereby saving energy.

[0061] In some embodiments, Figure 3 and Figure 4As shown, the parking mechanism 100 also includes a second connecting member 38, which includes a threaded portion 381 and a rotating portion 382, ​​the threaded portion 381 is fixedly connected to the housing of the reducer, the rotating portion 382 is connected to the threaded portion 381, the first connecting rod 31 is rotatably connected to the rotating portion 382, ​​and the second elastic member 35 is elastically connected between the first connecting rod 31 and the rotating portion 382.

[0062] Specifically, the second connecting member 38 is a half-thread bolt 50, that is, a part of the bolt 50 rod in the axial direction is a threaded rod with threads (i.e., the threaded portion 381) and the other part is a smooth rod without threads (i.e., the rotating portion 382). In this way, it can be fixedly connected to the housing of the reducer through the threaded portion 381, and can be rotatably connected to the first connecting rod 31 through the rotating portion 382. The second elastic member 35 is elastically connected between the first connecting rod 31 and the rotating portion 382.

[0063] In this way, the rotational stability of the second connecting member 38 and the first connecting rod 31 can be enhanced, and the second elastic member 35 is elastically connected between the pawl 32 and the rotating shaft 36. Since the position of the second connecting member 38 relative to the housing of the reducer remains unchanged, it is equivalent to the second elastic member 35 being elastically connected between the housing of the reducer and the first connecting rod 31, and the second elastic member 35 is elastically connected between the housing of the reducer and the rotating shaft 36, so as to make full use of the installation space, improve space utilization, and have a simpler layout.

[0064] In some embodiments, Figure 6 As shown, the second elastic member 35 is constructed as a second torsion spring, which is sleeved on the rotating portion 382 , and one end of the second torsion spring is connected to the rotating portion 382 and the other end is connected to the first connecting rod 31 .

[0065] For example Figure 5 As shown, the first connecting rod 31 is provided with a second mounting hole 312, and as shown in Figure 6 As shown, the rotating portion 382 is inserted into the second mounting hole 312, and the second torsion spring is sleeved on the rotating portion 382 and located in the second mounting hole 312. In this way, the arrangement space outside the second mounting hole 312 can be saved, thereby improving the space utilization rate. In addition, the second torsion spring is sleeved on the rotating portion 382 to enhance the structural stability of the second torsion spring.

[0066] In some embodiments, Figure 6 As shown, the first connecting rod 31 is provided with a boss 310 for slidingly cooperating with the housing of the reducer. Thus, by providing the boss 310, when the first connecting rod 31 moves, the boss 310 realizes sliding cooperation with the housing of the reducer, thereby ensuring the movement stability of the first connecting rod 31.

[0067] The utility model also discloses a vehicle.

[0068] The vehicle according to the embodiment of the present utility model comprises the parking mechanism 100 according to any one of the above embodiments.

[0069] According to the vehicle of the embodiment of the utility model, the pawl 32 of its parking mechanism 100 is rotatably connected to the first connecting rod 31, and when the pawl 32 contacts the tooth top of the parking ratchet 20, the pawl 32 will be forced to rotate to prevent the motor from stalling, and the first elastic member 33 can apply an elastic force to the pawl 32 to rotate around a first direction, so that the pawl 32 can be reset by using the elastic force of the first elastic member 33 after being forced to rotate, that is, the position of the pawl 32 can be adjusted by the first elastic member 33, thereby achieving the engagement of the pawl 32 with the parking ratchet 20 to reduce the risk of engagement.
