In the detailed description that follows, many specific details are presented in order to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present invention; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0035] The directional terms used in the following description refer to the directions shown in the figures and do not limit the specific structure of the braking device and vehicle of this utility model. It should also be noted that, in the description of this utility model, unless otherwise specified or limited, the terms "installation" and "connection" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; and can be directly or indirectly connected. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0036] In order to better understand the present invention, Figures 1 to 8 The braking device and the vehicle according to the embodiment of the present utility model are described in detail.

[0037] See also Figure 1 Combined with Figure 4 According to an embodiment of the present invention, a braking device 100 is proposed, including a base 10, a driving member 20, a moving assembly 30 and a braking member 40, wherein the driving member 20 is arranged on the base 10; the moving assembly 30 is arranged on the base 10 and connected to the driving member 20, and the driving member 20 can drive the moving assembly 30 to move along the first direction X on the base 10; the braking member 40 is rotatably connected to the base 10, and the braking member 40 includes a main body 41 and a clamping portion 42 arranged on the main body 41, and the clamping portion 42 protrudes from the main body 41. The braking member 40 is connected to the moving assembly 30, and the moving assembly 30 can drive the braking member 40 to rotate relative to the base 10, so that the clamping portion 42 rotates toward or away from the part to be locked.

[0038] Optionally, the base 10 can be a plate-shaped structure, and the driving member 20 is arranged on the base 10, which can form a stable support for the driving member 20. The driving member 20 can adopt a motor structure and be connected to the moving component 30 on the base 10. The driving member 20 can drive the moving component 30 to move back and forth on the base 10.

[0039] Optionally, the moving component 30 is movably connected to the base 10 and can move along the first direction X. During braking, the locked component needs to be braked or released, so the moving component 30 needs to move back and forth in the first direction X to achieve the braking or unlocking process. This application does not specifically limit the connection method between the moving component 30 and the base 10, and it is sufficient to ensure that the two are movably connected and form relative movement.

[0040] In this embodiment, the moving component 30 needs to be connected to the brake component 40. When the moving component 30 moves on the base 10, it can drive the brake component 40 connected thereto to rotate on the base 10 until it abuts against the part to be locked, completing the braking process; when it needs to be unlocked, the driving component 20 drives the moving component 30 to move in the opposite direction, so that the moving component 30 drives the brake component 40 to rotate in the opposite direction, so that the brake component 40 gradually moves away from the part to be locked, thereby completing the unlocking process.

[0041] The present application does not impose any special restrictions on the manner in which the brake member 40 is rotatably connected to the base 10. It is sufficient to ensure that the brake member 40 can rotate relative to the base 10. In this embodiment, the linear reciprocating movement of the moving component 30 in the first direction X is converted into a clockwise or counterclockwise reciprocating rotation of the brake member 40 on the base 10, so that the brake member 40 abuts against or moves away from the part to be locked to complete the braking or unlocking process.

[0042] Optionally, the brake member 40 includes a main body portion 41 and a clamping portion 42, and the clamping portion 42 is arranged to protrude from the main body portion 41. The clamping portion 42 can be set to a hook-shaped structure, and the part to be locked can be a ratchet structure. Therefore, when braking, the clamping portion 42 is clamped between the teeth of the ratchet through the hook-shaped structure, thereby completing the braking of the ratchet. This application does not specifically limit the specific structure of the brake member 40.

[0043] The present invention provides a braking device 100, which is provided with a driving member 20, a moving assembly 30 and a braking member 40 on a base 10, connects the driving member 20 with the moving assembly 30 and drives the moving assembly 30 to move along a first direction X, then connects the moving assembly 30 with the braking member 40 and drives the braking member 40 to rotate relative to the base 10, and utilizes the engaging portion 42 of the braking member 40 to engage with the part to be locked, thereby achieving braking of the part to be locked. The above process can transform the linear movement of the moving assembly 30 into the rotation of the braking member 40 to complete the braking process. Only the driving member 20 and the moving assembly 30 can drive the engaging of the braking member 40 with the part to be locked, simplifying the overall braking structure, making the structure simpler and easier to operate, reducing the complexity of the overall structure, reducing unnecessary component settings, saving the space occupied by the overall structure, making the structure more concise, and having better braking smoothness, better satisfying the user's braking experience.

[0044] As an alternative embodiment, see Figure 1 Combined with Figure 2 The moving assembly 30 includes a buffer member 31 having a buffer cavity 32 . One end of the buffer member 31 is connected to the driving member 20 and the other end is connected to the braking member 40 .

[0045] Taking into account the problem of stress concentration that may occur during the movement of the moving component 30 in the first direction X, a buffer member 31 is provided in the moving component 30 in this embodiment. The buffer member 31 has a buffer cavity 32. When the entire component moves along the first direction X, the buffer member 31 can better absorb the stress on the straight line, thereby forming safe stress protection for the structure.

[0046] One end of the buffer member 31 is connected to the driving member 20 and the other end is connected to the braking member 40. The driving member 20 can directly drive the buffer member 31 to move on the base 10, and then the buffer member 31 drives the braking member 40 to rotate, ensuring stress dispersion during the movement process, and can also play a certain anti-vibration and buffering role when an impact occurs in the moving direction.

[0047] The present application does not impose any special restrictions on the specific structure of the buffer member 31 , as long as it can enclose and form a buffer cavity 32 to absorb the stress in the moving direction. The buffer cavity 32 can also have various structural forms, which is not limited in the present application.

[0048] An embodiment of the present utility model provides a braking device 100, which provides a buffer member 31 in a moving component 30 and utilizes the buffering performance of the buffer member 31 to make the structure have better pressure-bearing capacity, thereby improving the balance stability of the moving component 30 during movement, thereby improving the braking stability of the entire structure, and at the same time having better safety protection performance to prevent components from being damaged, thereby providing reliable protection for sustainable braking.

[0049] As an alternative embodiment, see Figure 2 The buffer member 31 includes a first buffer portion 1 extending along the first direction X and a second buffer portion 2 extending along the second direction Y. The first buffer portion 1 and the second buffer portion 2 are alternately connected end to end and jointly enclose a buffer cavity 32. One of the two second buffer portions 2 opposite to each other in the first direction X is connected to the driving member 20 and the other is connected to the braking member 40. The first direction X and the second direction Y intersect.

[0050] In this embodiment, the buffer member 31 is configured as a connection form of the first buffer portion 1 and the second buffer portion 2, and the first buffer portion 1 and the second buffer portion 2 are used to jointly enclose a buffer cavity 32. Optionally, the first buffer portion 1 and the second buffer portion 2 can be metal plate structures, which is not limited in this application.

[0051] Optionally, the first buffer portion 1 extends along a first direction X and the second buffer portion 2 extends along a second direction Y. The first direction X and the second direction Y can be perpendicular to each other, so that the buffer member 31 as a whole forms a buffer cavity 32 with a rectangular outline. The present application does not specifically limit the specific shapes of the buffer member 31 and the buffer cavity 32, as long as they can enclose and form a buffer cavity 32 to absorb stress during movement.

[0052] Among them, the buffer member 31 is connected through the second buffer part 2 on both sides in the first direction X, one is connected to the driving member 20 and the other is connected to the brake member 40. Optionally, the connection method can be a detachable connection, so as to facilitate the disassembly and assembly operations between components. This application does not specifically limit the specific connection method.

[0053] An embodiment of the present invention provides a braking device 100, which forms a buffer cavity 32 by enclosing a first buffer portion 1 and a second buffer portion 2, and provides a structural form of a buffer member 31. The buffer member 31 has a simple structure and is easy to form by process, and effectively forms a vibration reduction and buffering effect during the movement process.

[0054] As an alternative embodiment, see Figure 1 Combined with Figure 3The driving member 20 includes a driving motor 21 and a driving shaft 22 connected to each other. The second buffer portion 2 is provided with a docking port 33 communicating with the buffer cavity 32. The buffer member 31 includes docking portions 3 arranged in pairs at the edge of the docking port 33. The paired docking portions 3 extend along the first direction X and clamp the driving shaft 22 for connection.

[0055] In order to enable the driving member 20 to drive the moving assembly 30 to move in the first direction X, in this embodiment, the driving member 20 is set to a structural form in which the driving motor 21 and the driving shaft 22 are connected. Under the action of the driving motor 21, the driving shaft 22 can be driven to move back and forth along the first direction X, so the moving assembly 30 can be connected to the driving shaft 22.

[0056] Since a buffer 31 is provided in the moving assembly 30, the buffer 31 can be connected to the drive shaft 22. Specifically, a docking port 33 connected to the drive shaft 22 is provided on the buffer 31. The docking port 33 faces the drive shaft 22 and is connected to the buffer cavity 32. Two docking parts 3 are provided at the edge of the docking port 33. Optionally, the docking part 3 can be a plate-like structure. The two docking parts 3 can be used to clamp the drive shaft 22, thereby forming a clamping connection with the buffer 31.

[0057] The drive shaft 22 serves as the output shaft of the drive motor 21. Optionally, a circular hole is formed in the drive shaft 22 and aligned with the circular holes on both sides of the docking portion 3. Spring pins are then symmetrically inserted into the corresponding circular holes in the docking portion 3 and the drive shaft 22, forming an interference fit with the holes, thereby forming a detachable connection. Because the buffer member 31 moves entirely along the first direction X and cannot move laterally, the docking portion 3 has openings on both sides to withstand the pressure transmitted by the spring pins.

[0058] When the driving motor 21 drives the driving shaft 22 to move back and forth along the first direction X, the driving shaft 22 drives the buffer member 31 clamped therewith to move along the first direction X on the base 10. On the basis of satisfying the connection between the buffer member 31 and the driving member 20, the buffer member 31 is used to achieve stress buffering during the movement.

[0059] An embodiment of the present invention provides a braking device 100, which realizes the connection between the buffer member 31 and the driving member 20 by setting a docking port 33 on the buffer member 31 and using the docking portion 3 to clamp and connect the driving shaft 22, providing a reliable detachable connection method and meeting the movement requirements of the buffer member 31.

[0060] As an alternative embodiment, see Figure 2 Combined with Figure 4 and Figure 5The buffer member 31 is provided with a transfer hole 34 communicating with the buffer cavity 32 , and the moving assembly 30 includes a transfer member 35 , one end of the transfer member 35 is inserted into the transfer hole 34 and the other end is detachably connected to the brake member 40 .

[0061] In this embodiment, an adapter 35 is further provided between the buffer 31 and the brake 40. One end of the adapter 35 is inserted into the adapter hole 34 provided on the buffer 31, and the other end is detachably connected to the brake 40, thereby forming a transfer relationship between the buffer 31 and the brake 40.

[0062] Optionally, the adapter 35 can adopt a rod-shaped structure, and a retaining spring is provided at one end of the adapter hole 34 of the buffer 31, which can prevent the adapter 35 from detaching from the adapter hole 34 and causing connection failure, thereby improving the connection stability between the adapter 35 and the buffer 31.

[0063] Optionally, a detachable connection method can be adopted between the adapter 35 and the brake component 40, so as to facilitate the staff to disassemble and assemble the two. This application does not specifically limit the specific detachable connection method.

[0064] An embodiment of the present invention provides a braking device 100, which provides an adapter 35 between the buffer 31 and the brake 40, and utilizes the adapter 35 to achieve the connection between the buffer 31 and the brake 40, which is beneficial to completing the drive transmission in the first direction X and meeting more connection requirements with the brake 40.

[0065] As an alternative embodiment, see Figures 4 to 6 The adapter 35 includes two limit baffles 5 and a transfer rod 6 connected to the limit baffles 5. The transfer rod 6 extends along the first direction X and is inserted into the transfer hole 34. The limit baffle 5 is provided with a limit protrusion 7 protruding along the first direction X. A limit gap 8 is formed between the limit protrusion 7 and the transfer rod 6. The end of the brake member 40 has a card slot 43, and the card slot 43 is clamped to the transfer rod 6. The two limit baffles 5 are clamped at the end of the brake member 40.

[0066] The specific structure of the adapter 35 in this embodiment is composed of a limit baffle 5 and a transfer rod 6. The adapter 35 is inserted into the transfer hole 34 of the buffer 31 through the transfer rod 6. A limit protrusion 7 is provided on the limit baffle 5. A limit gap 8 is formed between the limit protrusion 7 and the transfer rod 6. The end of the brake component 40 can be connected to the adapter 35 through the limit gap 8.

[0067] Optionally, a card slot 43 can be provided at the end of the brake member 40, and the adapter rod 6 can be clamped together by utilizing the card slot 43. Specifically, the adapter rod 6 is passed through the card slot 43 to form a clamping connection between the two. At the same time, the end portion of the brake member 40 can be inserted into the limiting gap 8 of the adapter 35, and the end of the brake member 40 is clamped and fixed by the clamping action of the limiting protrusion 7 and the adapter rod 6.

[0068] The two limiting baffles 5 are arranged relative to each other, so that the limiting protrusions 7 and limiting gaps 8 therein can be used to clamp and fix the end of the middle brake member 40, thereby improving the connection stability between the adapter 35 and the brake member 40 and ensuring the detachability between the two.

[0069] The above-mentioned connection method facilitates the disassembly and assembly operations of the staff. When the brake component 40 is disconnected from the adapter 35, the slot 43 at the end of the brake component 40 is pulled out from the adapter rod 6. The limiting protrusion 7 and the adapter rod 6 no longer form a clamping effect on the end of the brake component 40, and the brake component 40 can be separated from the adapter 35 more quickly.

[0070] Optionally, the surface of the limiting protrusion 7 can be designed to be semicircular, the purpose of which is to reduce the contact area to reduce wear, reduce the mutual wear when contacting with the end groove 43 of the brake member 40, and increase the service life of the parts.

[0071] The embodiment of the present utility model provides a braking device 100, which specifically sets the adapter 35 as a connection form of the limit baffle 5 and the adapter rod 6. When the adapter rod 6 is inserted into the adapter hole 34 to form a plug-in connection, the limit protrusion 7 on the limit baffle 5 is used to clamp and fix the end groove 43 of the brake member 40, thereby realizing a detachable connection between the brake member 40 and the adapter 35, providing a reliable connection method, facilitating the disassembly and assembly operations of the staff, and having better operational convenience.

[0072] As an alternative embodiment, see Figure 4 The moving assembly 30 includes a telescopic member 36 , which is sleeved on the transfer rod 6 , one end of the telescopic member 36 abuts against the buffer member 31 and the other end abuts against the limit baffle 5 .

[0073] Optionally, the telescopic member 36 can be sleeved on the transfer rod 6, and the two ends of the telescopic member 36 can be abutted between the limit baffle 5 and the buffer member 31, and the telescopic performance of the telescopic member 36 can be used to form a buffer connection between the buffer member 31 and the brake member 40.

[0074] Optionally, the telescopic member 36 can adopt a spring structure. When the driving shaft 22 of the driving member 20 is pushed forward, it will first drive the buffer member 31 to move forward and squeeze the telescopic member 36, thereby forcing the limit baffle 5 to push the tail of the brake member 40 to rotate counterclockwise and quickly pass through the clamping part 42 to engage with the triangular ratchet teeth of the ratchet, thereby realizing parking braking.

[0075] On the contrary, when the driving shaft 22 of the driving member 20 is retracted and pulled back backward, it will first drive the buffer member 31 to move backward. At the same time, the telescopic member 36 also rebounds quickly and drives the adapter rod 6 to move backward. Then the adapter 35 causes the tail of the brake member 40 to rotate clockwise and quickly move away from the triangular ratchet teeth of the ratchet wheel, thereby releasing the parking brake.

[0076] An embodiment of the present utility model provides a braking device 100, which provides a certain rebound force for brake unlocking by arranging a telescopic member 36 on the adapter rod 6, thereby facilitating the rapid completion of the brake release process. At the same time, it can provide a certain buffering and vibration reduction effect on the movement of the buffer member 31 and the adapter member 35, thereby forming a certain buffering protection for the moving parts.

[0077] As an alternative embodiment, see Figure 1 and Figure 2 The buffer member 31 includes a protrusion 4, and a movable groove 11 corresponding to the protrusion 4 is provided on the base 10. The movable groove 11 extends along the first direction X. The buffer member 31 is movably inserted into the movable groove 11 through the protrusion 4 so that the buffer member 31 moves along the first direction X on the base 10.

[0078] In order to enable the moving component 30 to move accurately in the first direction X, in this embodiment, a moving groove 11 extending in the first direction X is provided on the base 10, and a protrusion 4 corresponding to the moving groove 11 is provided on the buffer 31. The protrusion 4 is inserted into the moving groove 11 and moves in the moving groove 11, thereby realizing the relative movement of the buffer 31 on the base 10.

[0079] Optionally, two parallel movable grooves 11 can be set on the base 10, and two protrusions 4 can be set on the buffer 31. The two protrusions 4 are respectively inserted into the two movable grooves 11, which ensures that the buffer 31 moves along the first direction X while also ensuring the balance stability of the buffer 31 during the movement.

[0080] The present application does not impose any special restrictions on the specific dimensions of the protrusion 4 and the movable groove 11. It is sufficient to ensure that the movable groove 11 extends along the first direction X. In this way, the buffer member 31 can be moved along the first direction X after being inserted into the movable groove 11. The movable groove 11 plays a guiding role, and the buffer member 31 can only move back and forth in a straight line in this groove. Under the plug-in cooperation between the movable groove 11 and the protrusion 4, the movement of the buffer member 31 will not be offset.

[0081] An embodiment of the present utility model provides a braking device 100, by arranging a protrusion 4 on the buffer portion and arranging a movable groove 11 matching it on the base 10, the protrusion 4 is inserted into the movable groove 11 to form a movable matching relationship. The guiding function of the movable groove 11 provides precise guidance for the buffer member 31, improves the movement reliability in the first direction X, reduces the risk of offset of the movable component 30 during the movement process, and is conducive to achieving a precise braking process.

[0082] As an alternative embodiment, see Figure 1 Combined with Figure 7 The braking device 100 includes a positioning assembly 50, which includes a positioning shaft 51 and a positioning wheel 52 connected to each other. The positioning shaft 51 is inserted into the base 10 through the positioning wheel 52. The positioning shaft 51 passes through the braking member 40, and the braking member 40 can rotate around the positioning shaft 51.

[0083] Optionally, in this embodiment, a positioning assembly 50 is provided on the base 10, and is connected to the base 10 through a positioning wheel 52 therein. The positioning wheel 52 may be a spline structure with teeth, which is beneficial for improving the connection stability between the positioning assembly 50 and the base 10.

[0084] The positioning shaft 51 is vertically inserted into the base 10 through the positioning wheel 52 and passes through the brake member 40. When the brake member 40 is driven to rotate by the moving assembly 30, the brake member 40 can rotate around the positioning shaft 51 and rotate relatively with the positioning shaft 51 as the center until the brake member 40 forms a snap connection with the part to be locked.

[0085] Optionally, in order to reduce the wear between the brake part 40 and the positioning shaft 51 during rotation, a sleeve can be set at the positioning shaft 51, and the outer diameter of the positioning shaft 51 and the inner diameter of the sleeve are clearance-matched. The purpose of installing the sleeve made of wear-resistant material is to reduce the wear between the brake part 40 and the positioning shaft 51 during rotation, increase the service life of the structure, and effectively improve the long-term stability of the mechanism transmission.

[0086] In order to prevent the brake member 40 from moving in the axial direction of the positioning shaft 51, the upper end face of the brake member 40 is blocked by a retaining spring clamped in the groove of the positioning shaft 51, and the lower end face is directly pressed on the upper end face of the flange of the positioning shaft 51, thereby improving the connection stability between the brake member 40 and the positioning shaft 51.

[0087] An embodiment of the present utility model provides a braking device 100, which improves the stability of the braking member 40 during rotation by arranging a positioning assembly 50 on the base 10 to form a rotational fit with the braking member 40, extends the service life of the component, provides the braking member 40 with precise relative rotation, and thereby improves the reliability of the braking process.

[0088] According to an embodiment of the present invention, a vehicle is provided, comprising a rotating assembly 200 and the braking device 100 as described above. Figure 8 The rotating assembly 200 includes a driving motor 21 and a rotating wheel 202 . The driving motor 21 is connected to the rotating wheel 202 and can drive the rotating wheel 202 to rotate. The braking device 100 is clamped to the rotating wheel 202 through the clamping portion 42 to brake the rotating wheel 202 .

[0089] Normally, the driving motor 21 needs to be connected to the rotating wheel 202 to drive the rotation of the rotating wheel 202. Optionally, the rotating wheel 202 can be a ratchet structure. The rotating wheel 202 is installed on the output shaft of the driving motor 21 through an axial connector with a matching spline structure in the middle. The circumferential positioning is achieved by the spline structure and the key, and it is fixed by two Kimi screws to prevent it from moving up and down in the axial direction.

[0090] When braking the rotating wheel 202 , the brake member 40 engages the rotating wheel 202 via the engaging portion 42 , for example, engaging the engaging portion 42 in the tooth groove of the ratchet, so that the rotating wheel 202 stops rotating to complete the braking process.

[0091] Optionally, the rotating wheel 202 can adopt a triangular tooth ratchet. The biggest advantage of the cooperation between the ratchet and the brake member 40 is that only one-way parking braking can be achieved. For example, when the ratchet rotates counterclockwise, even if the brake member 40 is accidentally parked, it will not affect the output rotation of the interference main motor 201; when the ratchet rotates clockwise, the main motor 201 stops rotating due to being stuck. The use scenario of this design can be when the brake execution requirement is a linear telescopic execution brake. If the car is accidentally parked during driving, it will not affect the accidental sudden parking of the vehicle and cause an accident, thereby effectively protecting the safety of the people in the car.

[0092] The embodiment of the present utility model provides a braking device and a vehicle, which realizes braking of the component to be locked by arranging a driving member, a moving assembly and a braking member on a base, connecting the driving member to the moving assembly and driving the moving assembly to move in a first direction, then connecting the moving assembly to the braking member and driving the braking member to rotate relative to the base, and utilizing the clamping portion of the braking member to clamp with the component to be locked. The above process can transform the linear movement of the moving assembly into the rotation of the braking member to complete the braking process, and only utilizing the driving member and the moving assembly to drive the clamping of the braking member and the component to be locked, thereby simplifying the overall braking structure, making the structure simpler and easier to operate, reducing the complexity of the overall structure, reducing unnecessary component settings, saving the space occupied by the overall structure, making the structure more concise, and having better braking fluency, better satisfying the user's braking experience.

[0093] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
