[0031] The embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure and should not be construed as limiting the present disclosure.

[0032] The brake assembly 100 of the embodiments of the present disclosure includes a caliper body 1, a driving member 2, a cover plate 3, and a first brake member 4. One end of the caliper body 1 in the first direction (such as Figure 1 the left - right direction shown) is provided with an assembly hole 11. The caliper body 1 has a receiving groove 12. The receiving groove 12 and the assembly hole 11 are arranged in sequence and communicate with each other in the first direction. At least a part of the driving member 2 is located in the assembly hole 11. The cover plate 3 is provided at one end of the caliper body 1 to cover the assembly hole 11. The first brake member 4 is provided in the receiving groove 12. The driving member 2 is connected to the first brake member 4 and is used to drive the first brake member 4 to reciprocate relative to the caliper body 1 in the first direction to approach and move away from the brake disc.

[0033] Specifically, as Figures 1 - 3 shown, the right end of the caliper body 1 is provided with an assembly hole 11. The caliper body 1 can be a caliper housing. The assembly hole 11 is a through - hole. The assembly hole 11 is located at the right end of the receiving groove 12, and the left end of the assembly hole 11 communicates with the receiving groove 12. At least a part of the driving member 2 is located in the assembly hole 11. It can be understood that a part of the driving member 2 is located in the assembly hole 11 and another part of the driving member 2 is located outside the assembly hole 11. For example, the left end of the driving member 2 is located in the assembly hole 11 and the right end of the driving member 2 is located outside the assembly hole 11; or, the driving member 2 is completely located in the assembly hole 11. The cover plate 3 is provided at the right end of the caliper body 1 to cover the assembly hole 11.

[0034] The first brake member 4 is provided in the receiving groove 12. The left end of the driving member 2 is connected to the right end of the first brake member 4. The driving member 2 is used to drive the first brake member 4 to move left or right in the receiving groove 12. When the driving member 2 drives the first brake member 4 to move left, the first brake member 4 approaches the brake disc, and the first brake member 4 fits with the brake disc to achieve the braking effect on the brake disc. When the first brake member 4 moves right, the first brake member 4 moves away from the brake disc, and the first brake member 4 separates from the brake disc to release the braking.

[0035] Optionally, the first brake member 4 is a friction plate. The connection between the driving member 2 and the first brake member 4 is detachable, which is convenient for replacing the first brake member 4 when the first brake member 4 is worn, ensuring the braking performance of the first brake member 4.

[0036] The braking assembly 100 according to the embodiments of the present disclosure has a mounting hole 11 provided at one end of the caliper body 1, and the mounting hole 11 communicates with the receiving groove 12. In other words, one end of the mounting hole 11 is open (i.e., open to the outside of the caliper body), the other end of the mounting hole 11 (inside the caliper body) communicates with the receiving groove 12, and the opening is covered by the cover plate 3. During the installation process, at least part of the driving component 2 can be conveniently installed into the mounting hole 11 from this opening, and then the opening is covered by the cover plate 3 after installation. By opening to the outside of the caliper body 1, the possibility of installing components from the inside of the caliper body 1 into the mounting hole 11 can be reduced, there is no restriction on the internal structure of the caliper body 1, and the overall structure is simple, which is convenient for production and reduces the manufacturing cost at the same time.

[0037] Furthermore, in this embodiment, the cover plate 3 covers the end of the mounting hole 11 away from the receiving groove 12, preventing dust from entering, improving the reliability of the braking assembly 100 and enhancing the aesthetics of the caliper body 1 at the same time.

[0038] Furthermore, in this embodiment, an external thread 31 is provided on the outer peripheral surface of the cover plate 3, and an internal thread 111 that mates with the external thread 31 is provided on the inner wall surface of the end of the mounting hole 11 away from the receiving groove 12, facilitating the threaded connection between the cover plate 3 and the caliper body 1 and improving the assembly efficiency.

[0039] In some embodiments, the caliper body 1 includes a base portion 13 and a protruding portion 14. The protruding portion 14 is provided at one end of the base portion 13 in the first direction. The mounting hole 11 extends from the end of the protruding portion 14 away from the base portion 13 towards the base portion 13 and extends into the base portion 13.

[0040] Specifically, as Figure 1 and Figure 2 shown, the protruding portion 14 is provided at the right end of the base portion 13, and the protruding portion 14 protrudes to the right of the base portion 13. The mounting hole 11 extends from the right end of the protruding portion 14 towards the base portion 13 and extends into the base portion 13. The mounting hole 11 extends from the right end of the protruding portion 14 to the left into the base portion 13. It can be that the mounting hole 11 extends from the right end of the protruding portion 14 to the left to the right end face of the base portion 13, or it can be that the mounting hole 11 extends from the right end of the protruding portion 14 to the left into the interior of the base portion 13.

[0041] Optionally, since the receiving groove 12 in this embodiment is provided inside the base portion 13, by extending the mounting hole 11 from the right end of the protruding portion 14 to the left into the interior of the base portion 13 and connecting it to the receiving groove 12 on the base portion 13, at least part of the driving component 2 can be conveniently inserted into the mounting hole 11 from the right end of the mounting hole 11 and connected to the first braking member 4, reducing the installation difficulty.

[0042] Optionally, the protrusion 14 and the base portion 13 may be provided separately or integrally. For example, the protrusion 14 and the base portion 13 are formed by integral injection molding, integral casting, or other methods.

[0043] In some embodiments, the caliper body 1 further includes a boss portion 15. The boss portion 15 is provided at one end of the protrusion 14 away from the base portion 13. The boss portion 15 has a central cavity 151. The assembly hole 11 includes the central cavity 151. The cover plate 3 is provided in the central cavity 151 to seal one end of the central cavity 151 away from the protrusion 14.

[0044] Specifically, as Figures 1 - 3 shown, the boss portion 15 is provided at the right end of the protrusion 14. The boss portion 15 protrudes rightward from the protrusion 14. The central cavity 151 penetrates the boss portion 15 in the left-right direction. The cover plate 3 seals the right end face of the central cavity 151. When the cover plate 3 seals the assembly hole 11, the right end face of the cover plate 3 is flush with the right end face of the boss portion 15.

[0045] The assembly hole 11 includes a first section, a second section, and a third section arranged in sequence in the left-right direction. The first section is formed on the boss portion 15, the second section is formed on the protrusion 14, and the third section is formed on the base portion 13. That is to say, the assembly hole 11 sequentially penetrates the boss portion 15 and the protrusion 14 and partially penetrates the base portion 13 to communicate with the receiving groove 12 on the base portion 13.

[0046] Optionally, an external thread 31 is provided on the inner peripheral surface of the first section. By providing an internal thread 111 on the inner peripheral surface of the boss portion 15 that cooperates with the external thread 31 on the cover plate 3, and the boss portion 15 protrudes rightward from the protrusion 14, it is convenient to connect the cover plate 3 to the boss portion 15.

[0047] In some embodiments, the base portion 13 is integrally formed.

[0048] In this embodiment, at least part of the assembly hole 11 is formed on the base portion 13 and communicates with the receiving groove 12 on the base portion 13, and the right end of the assembly hole 11 is open, which is convenient to set the base portion 13 as an integral structure.

[0049] For example, the base portion 13 is formed by integral injection molding, integral casting, or other methods, which improves the structural strength of the base portion 13 and at the same time improves the integration degree of the brake assembly 100.

[0050] In some embodiments, there are at least two assembly holes 11. The at least two assembly holes 11 are arranged at intervals. There are at least two boss portions 15. At least part of the driving component 2 is at least two and corresponds to the at least two assembly holes 11 and the at least two boss portions 15 one by one.

[0051] Specifically, as Figure 1 and Figure 2As shown, for the sake of convenience in description, in this embodiment, two assembly holes 11 are taken as an example for description. The two assembly holes 11 are arranged at intervals in the front - rear direction, and both of the two assembly holes 11 are provided on the protruding part 14. The boss parts 15 are also provided in two and arranged at intervals in the front - rear direction. At least part of the driving component 2 is provided in two and arranged at intervals in the front - rear direction.

[0052] The part of the driving component 2 located in the front corresponds to the front assembly hole 11 and the front boss part 15, that is, the part of the driving component 2 located in the front is installed in the front assembly hole 11 and is connected to the front end of the first braking part 4. The part of the driving component 2 located in the rear corresponds to the rear assembly hole 11 and the rear boss part 15, that is, the part of the driving component 2 located in the rear is installed in the rear assembly hole 11 and is connected to the rear end of the first braking part 4. Through the connection of the driving component 2 with the front end and the rear end of the first braking part 4, the movement stability of the first braking part 4 is improved.

[0053] For example, the number of the assembly holes 11 is two, three, or four.

[0054] In some embodiments, the driving component 2 includes a transmission part 21 and a driving part. The transmission part 21 is arranged in the assembly hole 11. There is a through - hole on the cover plate 3, and one end of the transmission part 21 passes through the through - hole and is connected to the driving part.

[0055] Specifically, as Figures 1 - 3 shown, the transmission part 21 is located at the left end of the driving part. The right end of the transmission part 21 passes through the through - hole and is connected to the left end of the driving part. By providing a through - hole on the cover plate 3, it is convenient for the connection between the transmission part 21 and the driving part. The driving part drives the transmission part 21 to move, and the movement of the transmission part 21 drives the first braking part 4 to move left and right in the receiving groove 12, realizing the braking of the braking assembly 100.

[0056] For example, the driving part is a motor.

[0057] In some embodiments, the transmission part 21 includes a ball screw 211 and a piston. The ball screw 211 is connected to the driving part, the piston is sleeved on the outer periphery of the ball screw 211, and the piston is connected to the first braking part 4.

[0058] Specifically, as Figure 1 and Figure 2 shown, the piston is installed in the assembly hole 11 and can move in the left - right direction relative to the inner wall surface of the assembly hole 11. The left end of the piston is connected to the right end of the first braking part 4. The piston is sleeved on the ball screw 211 and is connected to the ball screw 211. By driving the ball screw 211 to rotate around the left - right direction, the piston is driven to move in the left - right direction, and further drives the first braking part 4 to move in the left - right direction.

[0059] When the transmission member 21 is installed, the left end of the assembly hole 11 communicates with the receiving groove 12, and the right end of the assembly hole 11 is open. Since the size of the receiving groove 12 in the left-right direction is limited, the piston can enter the assembly hole 11 through the left end of the assembly hole 11, and the ball screw 211 can enter the assembly hole 11 through the right end of the assembly hole 11, reducing the components that need to be installed from the inside of the caliper body 1 to the assembly hole 11 when installing the transmission member 21, and avoiding the limitation of the internal structure of the caliper body 1 caused by the need to install the transmission member 21.

[0060] Optionally, the ball screw 211 includes a screw rod and a screw nut. The outer surface of the screw rod is provided with a thread. The screw nut is sleeved on the screw rod and is threadedly connected to the screw rod. The piston is sleeved on the screw nut and is connected to the screw nut. The rotation of the screw nut around the left-right direction drives the movement of the screw nut in the left-right direction, and further drives the movement of the piston in the left-right direction. By sleeving the piston on the ball screw 211, the rotation of the ball screw 211 can drive the piston to move uniformly, and further drive the uniform movement of the first braking member 4.

[0061] When the driving member drives the ball screw 211 to rotate forward, the ball screw 211 rotates to drive the first braking member 4 to move leftward close to the brake disc, and the left end of the first braking member 4 fits with the right end of the brake disc to achieve the braking effect on the brake disc. When the driving member drives the ball screw 211 to rotate reversely, the ball screw 211 rotates to drive the first braking member 4 to move rightward away from the brake disc, and the separation of the first braking member 4 from the brake disc realizes the release of the braking.

[0062] For example, the piston can be fixedly connected to the ball screw 211 by means of clamping, bonding, welding, fixing with fasteners, etc. to ensure the connection reliability between the piston and the ball screw 211.

[0063] In some embodiments, there are at least two transmission members 21, and the at least two transmission members 21 are respectively arranged in the corresponding assembly holes 11.

[0064] Specifically, as Figure 1 and Figure 2 shown, the at least two transmission members 21 are arranged at intervals in the front-rear direction. The transmission member 21 located in the front is installed in the front assembly hole 11 and is connected to the front end of the first braking member 4, and the transmission member 21 located in the rear is installed in the rear assembly hole 11 and is connected to the rear end of the first braking member 4, improving the movement stability of the first braking member 4.

[0065] For example, the two transmission members 21 are driven by one driving member, or the two transmission members 21 are driven by two driving members.

[0066] In some embodiments, the braking assembly 100 further includes a stopper 5. The stopper 5 is provided at one end of the transmission member 21, and the stopper 5 cooperates with the cover plate 3 to prevent the transmission member 21 from disengaging from the assembly hole 11.

[0067] Specifically, as Figures 1 - 3 shown, the stopper 5 is connected to the right end of the transmission member 21, and the left end of the stopper 5 abuts against the right end of the cover plate 3, preventing the ball screw 211 from disengaging from the assembly hole 11 and improving the reliability of the ball screw 211.

[0068] In some embodiments, the stopper 5 is clamped on the outer periphery of one end of the transmission member 21, and the stopper 5 is connected to one end of the cover plate 3 in the first direction.

[0069] Specifically, as Figure 1 shown, a protrusion 212 is provided on the outer peripheral surface of the right end of the transmission member 21, and a groove 51 is provided on the stopper 5 for cooperating with the protrusion 212. By snapping the protrusion 212 on the transmission member 21 into the groove 51 on the stopper 5, the clamping connection between the stopper 5 and the transmission member 21 is realized, improving the connection firmness between the stopper 5 and the transmission member 21.

[0070] In some embodiments, the braking assembly 100 further includes a second braking member 6. The second braking member 6 is provided in the receiving groove 12. The second braking member 6 is located on the side of the first braking member 4 away from the driving component 2 and is arranged at an interval from the first braking member 4. The brake disc is used to be clamped between the first braking member 4 and the second braking member 6.

[0071] Specifically, as Figure 2 shown, the second braking member 6 is provided in the receiving groove 12 and is located on the left side of the first braking member 4. The brake disc is provided between the first braking member 4 and the second braking member 6. The first braking member 4 and the second braking member 6 cooperate to clamp, and the braking effect of the brake disc is realized through the frictional action between the first braking member 4 and the second braking member 6 and the brake disc.

[0072] For example, the second braking member 6 is a friction plate.

[0073] The brake of the present disclosure embodiment includes the braking assembly 100 adopting any one of the above embodiments.

[0074] For the brake in the embodiments of the present disclosure, an assembly hole 11 is provided at one end of the caliper body 1, and the assembly hole 11 communicates with the receiving groove 12. In other words, one end of the assembly hole 11 is open (i.e., open outside the caliper body), the other end of the assembly hole 11 (inside the caliper body) communicates with the receiving groove 12, and the opening is sealed by a cover plate 3. During the installation process, at least part of the driving component 2 can be easily installed into the assembly hole 11 from the opening, and then the opening is sealed by the cover plate 3 after installation. By opening outside the caliper body 1, the possibility of installing components from the inside of the caliper body 1 into the assembly hole 11 can be reduced, there is no restriction on the internal structure of the caliper body 1, and the overall structure is simple, which is convenient for production and reduces the manufacturing cost at the same time.
