Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a brake pedal and a vehicle. BACKGROUND

[0002] At present, when the pedal arm of the brake pedal rotates, the axial force is lacking, so that the damping force received by the pedal arm during rotation is small. In order to increase the damping force received by the pedal arm during rotation, the assembly size between the sleeve and the base can only be reduced, the friction between the bushing on the rotating shaft and the base is increased, so as to increase the damping force of the pedal arm during rotation. However, the assembly size between the sleeve and the base is reduced, which leads to the difficulty in assembly between the pedal arm and the sleeve and the base. After the pedal arm is rotated for many times, the damping force received by the pedal arm is reduced due to wear, and the pedal feeling is reduced. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a brake pedal and a vehicle, which can improve the brake pedal feeling.

[0004] In order to achieve the above purpose, the main technical scheme adopted by the present application includes:

[0005] In a first aspect, the present application provides a brake pedal, which comprises a base, a pedal arm, a sleeve and a damping assembly. The pedal arm and the sleeve are fixedly connected. The sleeve is rotatable relative to the base. The damping assembly is arranged in the sleeve and rotates synchronously with the sleeve. Along the axial direction of the sleeve, the two ends of the damping assembly are respectively in abutment with the pedal arm and the base.

[0006] The brake pedal provided by the present application embodiment has the pedal arm fixedly connected with the sleeve, the damping assembly sleeved on the sleeve, and the pedal arm driving the sleeve and the damping assembly to rotate relative to the base. Since the damping assembly is in abutment with the base, when the damping assembly rotates with the pedal arm and the sleeve, the relative rotation between the damping assembly and the base occurs, and the friction between the damping assembly and the base occurs. The friction serves as the damping force of the pedal arm during rotation, thereby improving the brake pedal feeling.

[0007] Optionally, the damping assembly comprises an elastic member and a damping block. The elastic member and the damping block are both sleeved on the sleeve. Along the axial direction of the sleeve, one side of the damping block is in abutment with the base, and the two ends of the elastic member are respectively in abutment with the other side of the damping block and the pedal arm.

[0008] In the above embodiment, the elastic member is sleeved on the sleeve and located between the pedal arm and the damping block. The elastic member exerts a force on the damping block, so that the damping block is pressed against the base. When the pedal arm drives the sleeve and the damping block to rotate, the continuous damping force between the damping block and the base is generated, and the damping force can remain basically consistent during the forward stroke and the return stroke of the pedal arm, thereby improving the quality of the brake pedal.

[0009] Optionally, the outer circumferential wall of the sleeve is provided with a groove extending along the axial direction of the sleeve, and the inner circumferential wall of the damping block is provided with a protrusion matched with the groove.

[0010] In the above embodiment, the groove extends along the axial direction of the sleeve towards the direction away from the pedal arm, and the protrusion on the inner circumferential wall of the damping block is matched in the groove to realize the clamping of the damping block and the sleeve, thereby realizing the synchronous rotation between the damping block and the sleeve.

[0011] Optionally, the damping block comprises a first part and a second part connected in sequence, the first part is closer to the pedal arm than the second part along the axial direction of the sleeve, the second part is in abutment with the base, the size of the second part is greater than that of the first part along the radial direction of the sleeve, and the elastic member is sleeved on the first part and in abutment with the second part.

[0012] In the above embodiment, the elastic member is sleeved on the first part, the first part guides the deformation of the elastic member, and the second part is in abutment with the elastic member to limit the displacement of the elastic member and reduce the probability of the elastic member being detached from the damping block.

[0013] Optionally, the size of the first part along the radial direction of the sleeve gradually increases from the first part to the second part.

[0014] In the above embodiment, the gap between the inner diameter of the elastic member and the outer diameter of the first part gradually decreases from the first part to the second part, the first part can guide the installation of the elastic member while reducing the relative displacement between the elastic member and the first part, and the deformation of the elastic member along the circumferential direction of the sleeve is reduced.

[0015] Optionally, the size of at least part of the first part along the radial direction of the sleeve is greater than the inner diameter of the elastic member in a free state.

[0016] In the above embodiment, when the elastic member is installed on the first part, the part of the first part with a size greater than the inner diameter of the elastic member in a free state abuts against the elastic member, so that the elastic member tightly abuts against the outer circumferential wall of the first part, and when the damping block rotates with the sleeve and the pedal arm, the elastic member also rotates with the damping block, thereby reducing the relative rotation between the elastic member and the damping block.

[0017] Optionally, the damping assembly further comprises a spring seat, the spring seat comprises a stop portion and a limiting portion connected, the outer diameter of the stop portion is greater than that of the limiting portion along the radial direction of the sleeve, the stop portion and the limiting portion are both sleeved on the sleeve, the elastic member is sleeved on the limiting portion, one side of the stop portion is in abutment with the pedal arm along the axial direction of the sleeve, and the other side of the stop portion is in abutment with the elastic member.

[0018] In the above embodiment, the elastic member is sleeved on the limiting portion and the first portion, and the two ends of the elastic member are respectively abutted against the stop portion and the second portion along the axial direction of the sleeve, so that the elastic member is limited, and when the pedal arm rotates, the elastic member can rotate synchronously with the damping block, the pedal arm and the sleeve, thereby reducing the deformation of the elastic member along the circumferential direction of the sleeve.

[0020] Optionally, the brake pedal further comprises a bushing, the bushing is rotatably sleeved on the rotating shaft, and the sleeve is sleeved on the bushing.

[0021] In the above embodiment, when the pedal arm drives the sleeve to rotate relative to the rotating shaft, the sleeve sleeved on the bushing can reduce the wear of the sleeve, and only the bushing needs to be replaced during maintenance, thereby saving cost.

Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

The terms "first", "second" and the like in the specification and claims of the present application and the above description of drawings are used to distinguish different objects, and are not intended to describe a particular order or primary and secondary relationship.

[0036] In the present application, the phrase "embodiment" means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.

[0037] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection", "attach" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] In the present application, the term "and / or" is only a description of the association relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the present application generally represents an "or" relationship between the front and rear associated objects.

[0039] In the present application, "a plurality of" refers to more than two (including two), and similarly, "a plurality of groups" refers to more than two groups (including two groups), and "a plurality of pieces" refers to more than two pieces (including two pieces).

[0040] At present, when the pedal arm of the brake pedal rotates, the lack of axial force causes the damping force received by the pedal arm during rotation to be very small. In order to increase the damping force received by the pedal arm during rotation, the assembly size between the sleeve and the base opening can only be reduced, the friction between the bushing on the shaft and the sidewall of the base is increased, and thus the damping force of the pedal arm during rotation is increased. However, this method has the following disadvantages: the assembly size between the sleeve and the base is reduced, which causes difficulty in assembling the pedal arm and the sleeve with the base, and batch production cannot be realized; after the pedal arm is rotated for many times, the damping force received by the pedal arm is reduced due to wear, which reduces the pedal feeling. This method is unreliable and the damping force is not adjustable.

[0041] In view of this, the present application provides a brake pedal which can improve the pedal feeling of the brake pedal and the damping force is adjustable.

[0042] In the first aspect, with reference to Figure 1 and Figure 2 The present application provides a brake pedal, which comprises a base 1, a pedal arm 2, a sleeve 3 and a damping assembly 4. The pedal arm 2 and the sleeve 3 are fixedly connected, and the sleeve 3 is rotatable relative to the base 1. The damping assembly 4 is arranged in the sleeve 3 and rotates synchronously with the sleeve 3. Along the axial direction X of the sleeve 3, the two ends of the damping assembly 4 respectively abut against the pedal arm 2 and the base 1.

[0043] The pedal arm 2 and the sleeve 3 are fixedly connected, and the damping assembly 4 is sleeved on the sleeve 3. The pedal arm 2 drives the sleeve 3 and the damping assembly 4 to rotate relative to the base 1. Since the damping assembly 4 abuts against the base 1, when the damping assembly 4 rotates with the pedal arm 2 and the sleeve 3, relative rotation occurs between the damping assembly 4 and the base 1, and friction occurs between the damping assembly 4 and the base 1. The friction serves as the damping force of the pedal arm 2 during rotation, thereby improving the pedal feeling of the brake pedal.

[0044] It should be noted that the damping assembly 4 and the sleeve 3 can be connected in a clamping or screwing manner, so as to realize synchronous rotation of the damping assembly 4 and the sleeve 3.

[0045] For example, at least part of the damping assembly 4 is made of wear-resistant material, such as polyoxymethylene (POM) or the like, which abuts against the base 1.

[0046] Optionally, with reference to Figure 1 and Figure 2The damping assembly 4 comprises an elastic member 41 and a damping block 42, both of which are sleeved on the sleeve 3. Along the axial direction X of the sleeve 3, one side of the damping block 42 abuts against the base 1, and both ends of the elastic member 41 abut against the other side of the damping block 42 and the pedal arm 2 respectively.

[0047] The elastic member 41 is sleeved on the sleeve 3 and located between the pedal arm 2 and the damping block 42. The elastic member 41 applies a force to the damping block 42, so that the damping block 42 is pressed against the base 1. When the pedal arm 2 drives the sleeve 3 and the damping block 42 to rotate, a continuous damping force is generated between the damping block 42 and the base 1, and the damping force can remain basically consistent during the forward stroke and the return stroke of the pedal arm 2, thereby improving the quality of the brake pedal.

[0048] Exemplarily, the compression amount of the elastic member 41 can be adjusted according to the actual damping force requirement, so as to change the damping force received by the pedal arm 2, thereby realizing the adjustability of the pedal damping force.

[0049] Optionally, referring to Figure 2 The outer peripheral wall of the sleeve 3 is provided with a groove 31 extending along the axial direction X of the sleeve 3, and the inner peripheral wall of the damping block 42 is provided with a protrusion 421 matched with the groove 31.

[0050] The groove 31 extends along the axial direction X of the sleeve 3 towards the direction away from the pedal arm 2, and the protrusion 421 on the inner peripheral wall of the damping block 42 is matched in the groove 31, so as to realize the clamping of the damping block 42 and the sleeve 3, thereby realizing the synchronous rotation between the damping block 42 and the sleeve 3.

[0051] During installation, only the protrusion 421 of the damping block 42 needs to be aligned with the groove 31 of the sleeve 3, and then the damping block 42 is sleeved on the sleeve 3, so that the structure is simple and the installation is convenient.

[0052] Exemplarily, along the circumferential direction of the sleeve 3, the sleeve 3 is provided with a plurality of grooves 31, and the plurality of grooves 31 are arranged at intervals. The inner peripheral wall of the damping block 42 is provided with a plurality of protrusions 421, and each protrusion 421 is matched with a corresponding groove 31.

[0053] Optionally, referring to Figure 2 The damping block 42 comprises a first part 422 and a second part 423 connected in sequence. Along the axial direction X of the sleeve 3, the first part 422 is closer to the pedal arm 2 than the second part 423, and the second part 423 abuts against the base 1. Along the radial direction of the sleeve 3, the size of the second part 423 is larger than that of the first part 422. The elastic member 41 is sleeved on the first part 422 and abuts against the second part 423.

[0054] The second part 423 is located on the side of the first part 422 away from the pedal arm 2, and is used to abut against the base 1 and generate friction between the base 1 and the second part 423 when the pedal arm 2 rotates, thereby improving the quality of the brake pedal.

[0055] The elastic member 41 is sleeved on the first part 422, and the first part 422 guides the deformation of the elastic member 41, so that the elastic member 41 can be centered and the probability of misalignment is reduced; the second part 423 abuts against the elastic member 41 to limit the displacement of the elastic member 41 and reduce the probability of the elastic member 41 being pulled out of the damping block 42.

[0056] Optionally, referring to Figure 2 , the size of the first part 422 in the radial direction of the sleeve 3 gradually increases from the first part 422 to the second part 423. The elastic member 41 is sleeved on the first part 422, and the gap between the inner diameter of the elastic member 41 and the outer diameter of the first part 422 gradually decreases from the first part 422 to the second part 423. The first part 422 can guide the elastic member 41 while reducing the relative displacement between the elastic member 41 and the first part 422, and reducing the deformation of the elastic member 41 in the circumferential direction of the sleeve 3.

[0057] In one specific embodiment, the damping block 42 further comprises a third part, which is located on the side of the first part 422 away from the second part 423. The outer diameter of the third part is smaller than the outer diameter of the first part 422, and the elastic member 41 passes through the third part to cooperate with the first part 422.

[0058] Optionally, referring to Figure 2 , the size of at least part of the first part 422 in the radial direction of the sleeve 3 is greater than the inner diameter of the elastic member 41 in a free state. The outer diameter of at least part of the first part 422 is greater than the inner diameter of the elastic member 41 in a free state. When the elastic member 41 is installed on the first part 422, the part of the first part 422 that is larger than the inner diameter of the elastic member 41 in a free state abuts against the elastic member 41, so that the elastic member 41 tightly abuts against the outer peripheral wall of the first part 422. When the damping block 42 rotates with the sleeve 3 and the pedal arm 2, the elastic member 41 also rotates with the damping block 42 due to the close cooperation between the elastic member 41 and the first part 422, thereby reducing the relative rotation between the elastic member 41 and the damping block 42 and reducing the deformation of the elastic member 41 in the circumferential direction.

[0059] Optionally, referring to Figure 1 and Figure 2The damping assembly 4 further comprises a spring seat 43, the spring seat 43 comprises a stop portion 431 and a limiting portion 432 connected, in the radial direction of the sleeve 3, the outer diameter of the stop portion 431 is greater than the outer diameter of the limiting portion 432, the stop portion 431 and the limiting portion 432 are sleeved on the sleeve 3, the elastic member 41 is sleeved on the limiting portion 432, in the axial direction X of the sleeve 3, one side of the stop portion 431 abuts against the pedal arm 2, and the other side of the stop portion 431 abuts against the elastic member 41.

[0060] The elastic member 41 is sleeved on the limiting portion 432, the limiting portion 432 guides the axial deformation of the elastic member 41, so that the elastic member 41 can be centered and the probability of misalignment is reduced; one end of the elastic member 41 abuts against the stop portion 431, so as to reduce the influence of the rotation of the pedal arm 2 on the elastic member 41, thereby reducing the deformation of the elastic member 41 in the circumferential direction thereof.

[0061] The elastic member 41 is sleeved on the limiting portion 432 and the first portion 422, and in the axial direction X of the sleeve 3, both ends of the elastic member 41 abut against the stop portion 431 and the second portion 423 respectively, so as to limit the elastic member 41, and when the pedal arm 2 rotates, the elastic member 41 can rotate synchronously with the damping block 42, the pedal arm 2 and the sleeve 3, thereby reducing the deformation of the elastic member 41 in the circumferential direction of the sleeve 3.

[0062] Optionally, referring to Figure 2 The brake pedal further comprises a rotating shaft 5, the rotating shaft 5 is arranged on the base 1, and the sleeve 3 is rotatably sleeved on the rotating shaft 5. The rotating shaft 5 is arranged on the base 1, and the sleeve 3 is rotatable relative to the rotating shaft 5, so as to realize the rotation of the pedal arm 2, thereby realizing the brake function of the brake pedal.

[0063] Optionally, referring to Figure 2 The brake pedal further comprises a bushing 6, the bushing 6 is rotatably sleeved on the rotating shaft 5, and the sleeve 3 is sleeved on the bushing 6.

[0064] When the pedal arm 2 drives the sleeve 3 to rotate relative to the rotating shaft 5, the sleeve 3 sleeved on the bushing 6 can reduce the abrasion of the sleeve 3, and only the bushing 6 needs to be replaced during maintenance, thereby saving cost.

In addition, the friction force between damping block 42 and base 1 can be adjusted by replacing elastic member 41 or adjusting the compression amount of elastic member 41, so as to realize the adjustable damping force of pedal arm 2.
