[0043] Compared with the prior art, the utility model has achieved the following technical effects:

[0044] When the user steps on the first end of the pedal arm, the pedal arm rotates around the connection point between the second end of the pedal arm and the pedal seat. During the rotation of the pedal arm, the force applied by the user is transmitted to the elastic member through the conductive surface. On the one hand, because the conductive surface in the utility model is an inclined surface or a curved surface, when the force applied by the user is transmitted to the conductive surface, the force is divided into two parts by the conductive surface, one part is a force parallel to the inclined surface direction or the tangent direction of the curved surface, and the other part is a force perpendicular to the inclined surface or the tangent direction of the curved surface. The force parallel to the inclined surface direction or the tangent direction of the curved surface cannot compress the elastic member, causing the elastic member to deform. Only the force perpendicular to the tangent direction of the inclined surface or the vertical curved surface can drive the elastic member to move. This makes the distance that the user steps on the pedal arm nonlinearly related to the compression distance of the elastic member. The elastic member can output a force value that is nonlinearly related to the distance that the user steps on the pedal arm, that is, the elastic member in the utility model can generate a force value that is nonlinearly related to the distance that the user steps on the pedal arm. In other words, the brake pedal in the utility model has a nonlinear braking function.

[0045] On the other hand, since the bearing part and the conducting part are arranged parallel to the end face of the elastic part, the elastic part is evenly stressed and is not prone to tilting or lateral movement. Since the guide part is arranged along the axial direction of the elastic part, the elastic part will not move laterally during the deformation process. Based on the arrangement of the bearing part, the conducting part and the guide part, the elastic part in the utility model can be deformed along the axial direction of the elastic part when subjected to force. This not only avoids the abnormal noise caused by the lateral movement of the elastic part and the friction with the surrounding components, but also the deformation of the elastic part along the axial direction of the elastic part is a regular movement. This also avoids the problem of vibration and noise caused by the irregular movement of the elastic part along the non-axial deformation. At the same time, since only a single elastic part is used in the utility model, the abnormal noise emitted by multiple elastic parts during the matching process is avoided.

[0046] In summary, the utility model can not only ensure that the force output by the elastic member is nonlinearly related to the distance the user steps on the pedal arm, that is, the brake pedal has a nonlinear braking function, but also eliminate abnormal noise during the actuation of the brake pedal.

DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0060] like Figure 1-Figure 9As shown, the utility model discloses a brake pedal, comprising a pedal arm 1, a first end of the pedal arm 1 is used for a user to step on; a pedal seat 2, the pedal seat 2 is rotatably connected to the second end of the pedal arm 1; an elastic member 3, the elastic member 3 is located between the pedal arm 1 and the pedal seat 2; a guide member, the guide member is located inside the elastic member 3 and / or outside the elastic member 3, and the guide member is arranged along the axial direction of the elastic member 3; a conducting part, the conducting part is located between the first end of the elastic member 3 and the pedal arm 1; the side of the conducting part facing the pedal arm 1 is a conducting surface 10, and the conducting surface 10 is an inclined surface or a curved surface; a bearing part, the bearing part is located between the second end of the elastic member 3 and the pedal seat 2, and the contact area between the bearing part and the elastic member 3 and the contact area between the conducting part and the elastic member 3 are both arranged parallel to the end surface of the elastic member 3.

[0061] When the user steps on the first end of the pedal arm 1, the pedal arm 1 rotates around the connection point between the second end of the pedal arm 1 and the pedal seat 2. During the rotation of the pedal arm 1, the force applied by the user is transmitted to the elastic member 3 through the conductive surface 10. On the one hand, because the conductive surface 10 in the utility model is an inclined surface or a curved surface, when the force applied by the user is transmitted to the conductive surface 10, the force is divided into two parts by the conductive surface 10, one part is a force parallel to the inclined surface direction or the tangent direction of the curved surface, and the other part is a force perpendicular to the inclined surface or the tangent direction of the curved surface. The force parallel to the inclined surface direction or the tangent direction of the curved surface cannot compress the elastic member 3, causing the elastic member 3 to deform. Only the force perpendicular to the inclined surface or the tangent direction of the curved surface can drive the elastic member 3 to move. This makes the distance that the user steps on the pedal arm 1 and the compression distance of the elastic member 3 have a nonlinear relationship. In other words, the distance that the user steps on the pedal arm 1 and the force received by the elastic member 3 and the force output by the elastic member 3 have a nonlinear relationship. Therefore, the brake pedal in the utility model has a nonlinear braking function.

[0062] On the other hand, since the bearing part and the conducting part are arranged parallel to the end face of the elastic member 3, the elastic member 3 is subjected to uniform force and is not prone to tilting or lateral movement. Since the guide member is arranged along the axial direction of the elastic member 3, the elastic member 3 will not move laterally during the deformation process. Based on the arrangement of the bearing part, the conducting part and the guide member, the elastic member 3 in the utility model can be deformed along the axial direction of the elastic member 3 when subjected to force. This not only avoids the abnormal noise caused by the lateral movement of the elastic member 3 and the friction with the surrounding components, but also the deformation of the elastic member 3 along the axial direction of the elastic member 3 is a regular movement. This also avoids the problem of irregular movement of the elastic member 3 along the non-axial deformation, which generates vibration and noise. At the same time, since only a single elastic member 3 is used in the utility model, the abnormal noise emitted by multiple elastic members 3 during the matching process is avoided.

[0063] In summary, the utility model can not only ensure that the distance the user steps on the pedal arm 1 and the force output by the elastic member 3 are in a nonlinear relationship, that is, the brake pedal has a nonlinear braking function, but also eliminate abnormal noise during the operation of the brake pedal.

[0064] Among them, it should be noted that in the utility model, the force applied by the user to the pedal arm 1 must pass through the conduction surface 10 before being transmitted to the elastic member 3. When passing through the conduction surface 10, the force applied by the user is differentiated, and a part of the force is differentiated into a force in the direction perpendicular to the inclined plane or the direction perpendicular to the tangent of the curved surface, and the remaining force is differentiated into a force along the inclined plane, that is, parallel to the inclined plane direction or parallel to the tangent direction of the curved surface. Obviously, the force applied by the user is "weakened" when passing through the conduction surface 10, so that the force received by the elastic member 3 is less than the force applied by the user. In this way, the distance that the user steps on the pedal arm 1 is nonlinearly related to the compression distance and output force value of the elastic member 3. Then the braking force output by the brake pedal is also nonlinearly related to the distance that the user steps on the pedal arm 1, thereby realizing nonlinear braking of the brake pedal.

[0065] Through the cooperation of the conductive surface 10 and the elastic member 3, a vehicle using the brake pedal of the utility model can apply brakes gradually and gently, thereby ensuring that the vehicle stops or decelerates smoothly. That is, compared with a linear brake pedal, the nonlinear braking function enables the brake pedal of the utility model to provide a smoother braking effect when driving at low speeds or when the vehicle starts and stops frequently, thereby reducing the discomfort of passengers.

[0066] The elastic member 3 can be a spring made of elastic metal or composite material or other forms of elastic structural members. In the utility model, the conducting part and the bearing part have various shapes, and it is only necessary to ensure that the area where the conducting part contacts the elastic member 3, the area where the bearing part contacts the elastic member 3, and the end surface of the elastic member 3 are kept parallel. The side of the conducting part facing the elastic member 3 and the side of the bearing part facing the elastic member 3 can be a plane, a curved surface, or other shapes.

[0067] In the utility model, a pedal pad 17 is provided at the first end of the pedal arm 1 for the user to step on the pedal arm 1 during manual driving, and the grip and friction between the user's foot and the first end of the pedal arm 1 are increased, so that the user can step on the first end of the pedal arm 1 stably, avoiding the problem of the user's foot slipping on the first end of the pedal arm 1, and improving the comfort of the user when stepping on the pedal arm 1; moreover, the wear of the pedal arm 1 due to long-term use is reduced, and the service life of the pedal arm 1 is extended.

[0068] like Figure 1-Figure 2 , Fig. 9 As shown, the utility model provides a first push rod 9 between the pedal arm 1 and the transmission part, the first end of the first push rod 9 is connected to the side of the pedal arm 1 close to the pedal seat 2, and the second end of the first push rod 9 abuts against the side of the transmission part facing the pedal arm 1.

[0069] The first end of the first push rod 9 is connected to the side of the pedal arm 1 close to the pedal seat 2 by welding, bolt connection, or other fixed connection methods. The second end of the first push rod 9 is in contact with the side of the transmission part facing the pedal arm 1. This allows the first push rod 9 to move along the transmission surface 10 under the action of a force parallel to the inclined surface direction or parallel to the tangent of the curved surface when transmitting the force of the pedal arm 1 to the transmission surface 10, so that the transmission surface 10 can better realize the function of transmitting the force from the pedal arm 1 to the elastic member 3. Compared with the pedal arm 1 directly transmitting the force to the transmission part, the first push rod 9 can transmit the force received by the pedal arm 1 to the transmission surface 10 more accurately, reducing the problems of lateral force, unnecessary friction and wear caused in the process of force transmission, and making the force transmission between the pedal arm 1, the bearing part and the elastic member 3 more stable and effective. The shape of the first push rod 9 can also be adjusted accordingly according to customer needs.

[0070] Furthermore, the guide member in the utility model has various forms.

[0071] For example, when the guide member is disposed inside the elastic member 3, the guide member can be specifically a guide rod, which is disposed along the axial direction of the elastic member 3, and a guide hole matching the guide rod is disposed on the pedal. The guide rod is disposed along the axial direction of the elastic member 3, so that when the elastic member 3 is compressed by force, it can move along the axial direction of the elastic member 3 itself, without being tilted and compressed, thereby avoiding the problem of abnormal noise caused by contact with other structures due to tilted compression. In addition, the diameter of the guide hole is not less than the diameter of the guide rod, so that when the pedal arm 1 rotates toward the pedal seat 2, the guide rod can pass through the guide hole, thereby avoiding the interference of the guide rod with the pedal arm 1, so that the pedal arm 1 can rotate toward the pedal seat 2, that is, the braking function of the brake pedal can be smoothly realized.

[0072] When the guide member is arranged on the outside of the elastic member 3, the guide member includes a first guide sleeve, which is arranged on the pedal seat 2. The first guide sleeve has a first cavity opened along the axial direction of the elastic member 3, and the elastic member 3 is arranged in the first cavity. The first cavity and the elastic member 3 are slidably matched. The movement of the elastic member 3 is guided by the axially arranged first cavity, so that the elastic member 3 moves along the axial direction of the elastic member 3 when it is compressed, and the elastic member 3 is prevented from being tilted and compressed (tilted compression refers to the movement of the spring in a direction other than the axial direction of the spring when it is compressed). The first cavity and the elastic member 3 are clearance matched, but the clearance will not be too large to prevent the first cavity from failing to guide the elastic member 3, and the clearance will not be too small to prevent the first cavity from generating friction with the elastic member 3 and hindering the movement of the elastic member 3.

[0073] Alternatively, the guide member may not adopt the above structure. In this case, the guide member includes a second guide sleeve and a telescopic rod. The second guide sleeve is arranged on the pedal seat 2. The second guide sleeve and the telescopic rod are both arranged along the axial direction of the elastic member 3. The first end of the second guide sleeve is connected to the bearing part, and the first end of the telescopic rod is connected to an end of the elastic member 3 close to the pedal arm 1. The second guide sleeve and the telescopic rod are slidably matched.

[0074] Since the second sleeve and the telescopic rod are both arranged along the axial direction of the elastic member 3, the elastic member 3 can move along the axial direction of the elastic member 3 when it is pressed and moved, thereby avoiding the tilting compression of the elastic member 3. It should be noted that the second guide sleeve can be arranged on the outside of the elastic member 3 or on the inside of the elastic member 3, and the specific arrangement form depends on the required spring type and the actual working conditions. The telescopic rod is only a name, and the telescopic in the telescopic rod means that the telescopic rod can slide in the second guide sleeve, and the telescopic rod itself cannot be telescoped, and a limiter 15 is provided in the second guide sleeve to prevent the telescopic rod from running out of the second guide sleeve. The first end of the second guide sleeve refers to the end fixed on the pedal seat 2, and the first end of the telescopic rod refers to the end away from the pedal seat 2.

[0075] The guide rod and the first guide sleeve or the second guide sleeve disposed outside the elastic member 3 may exist at the same time or separately. When the guide rod and the first guide sleeve or the second guide sleeve disposed outside the elastic member 3 exist at the same time, it is equivalent to setting two sets of guide mechanisms, through which the elastic member 3 can be better limited, further avoiding lateral movement or tilting of the elastic member 3 during deformation, and further eliminating abnormal noise during the actuation of the brake pedal in the utility model.

[0076] like Figure 3-Figure 6 As shown, the conduction part in the utility model includes a first sliding body 11, and a conduction surface 10 is provided on the side of the first sliding body 11 facing the pedal arm 1, and the first sliding body 11 has a second cavity arranged axially along the elastic member 3; the bearing part includes a second sliding body 12, and the first end of the second sliding body 12 is connected to the pedal seat 2, and the second sliding body 12 has a third cavity arranged axially along the elastic member 3, and the first sliding body 11 and the second sliding body 12 are slidably matched. The brake pedal also includes a first limit member 15, and the first limit member 15 includes a first connecting portion 18 arranged at the first end of the first sliding body 11, and a second connecting portion 19 arranged at the second end of the second sliding body 12, and the first connecting portion 18 is connected to the second connecting portion 19.

[0077] The conductive surface 10 in the present invention can be integrally provided with the first sliding body 11, in which case the side of the first sliding body 11 facing the pedal arm 1 is the conductive surface 10; or the conductive surface 10 and the first sliding body 11 can be separately provided, and the conductive surface 10 is provided on the cover plate 14, and the top of the cover plate 14 is the conductive surface 10. In this case, the present invention can make the first sliding body 11 into a universal part. When the customer has different requirements for the pedaling force, it is only necessary to change the shape of the conductive surface 1 on the cover plate 14 and the elastic member 3, and the conductive surface 10 can be adjusted by changing the shape of the conductive surface 1 on the cover plate 14. Compared with the manner in which the guide surface 10 and the first sliding body 11 are integrally arranged, at this time, the utility model does not need to re-mold the first sliding body 11 and the conductive surface 10, and only needs to re-mold the cover plate 14. Compared with the first sliding body 11 and the conductive surface 10 arranged integrally, the volume of the cover plate 14 is smaller, and more cover plates 14 can be produced by one mold. Obviously, this greatly reduces the development cost (development cost includes mold opening cost) and development cycle (development cycle includes production cycle) of the utility model when changing the conductive surface 10 according to customer needs.

[0078] Among them, when the transmission part and the bearing part are arranged in the above-mentioned form, the end of the elastic member 3 facing the transmission part is connected to the end of the first sliding body 11 facing the elastic member 3, and the end of the elastic member 3 facing the bearing part is connected to the end of the bearing part facing the elastic member 3. The sliding cooperation between the first sliding body 11 and the second sliding body 12 means that the first sliding body 11 can be sleeved outside the second sliding body 12, and the second sliding body 12 can be sleeved outside the first sliding body 11, and when the first sliding body 11 moves to a certain distance away from the second sliding body 12, the first connecting part 18 and the second connecting part 19 will be connected together to prevent the first sliding body 11 from separating from the second sliding body 12. Figure 4 As shown, the first connection portion 18 and the second connection portion 19 may specifically be mutually matching clamping portions.

[0079] Further, the brake pedal also includes a third guide sleeve 13, a first end of the third guide sleeve 13 is arranged on the pedal seat 2, the third guide sleeve 13 is sleeved on the second sliding body 12 or the outer side of the second sliding body 12, and the third guide sleeve 13 is specifically sleeved on the first sliding body 11 or the second sliding body 12, which depends on which structure of the first sliding body 11 and the second sliding body 12 is located on the outer side. For example, when the second sliding body 12 is located on the outer side of the first sliding body 11, the third guide sleeve 13 is sleeved on the outer side of the second sliding body 12, and the brake pedal also includes a second limiting member 15, the second limiting member 15 includes a third connecting portion 20 arranged on the side of the first sliding body 11, and a fourth connecting portion 21 arranged on the second end of the third guide sleeve 13, and the third connecting portion 20 is connected to the fourth connecting portion 21, as shown in FIG. Figure 3-Figure 4As shown, the third connection part 20 and the fourth connection part 21 can be specifically snap-fitted. The second limiter 15 can be used to limit the second slide 12 for a second time, so as to prevent the first slide 11 from being separated from the second slide 12 when the first limiter 15 fails, and ensure that the first end of the second slide 12 compresses the elastic member 3.

[0080] Furthermore, if Figure 3 , Figure 5 , Figure 7 As shown, in the present invention, a cover plate 14 is provided between the conductive surface 10 and the first sliding body 11, a sixth connecting portion 23 is provided on a side of the cover plate 14 facing the first sliding body 11, a fifth connecting portion 22 is provided on a side of the first sliding body 11 facing the cover plate 14, and the fifth connecting portion 22 is connected to the sixth connecting portion 23. The arrangement of the cover plate 14 makes it more convenient to replace the first sliding body 11. The specific connection method of the fifth connecting portion 22 and the sixth connecting portion 23 can be a snap connection.

[0081] In the utility model, after the cover plate 14 and the first sliding body 11 are installed together, the fifth connecting portion 22 and the sixth connecting portion 23 limit the movement of the cover plate 14 and the first sliding body 11 in the up-down direction and the left-right direction; the wedge block on the top of the first sliding body 11 and the wedge block on the side of the cover plate 14 facing the first sliding body 11 cooperate to prevent the cover plate 14 and the first sliding body 11 from moving in the front-back direction, thereby realizing the limitation of the cover plate 14 and the first sliding body 11 in three directions, so that after the cover plate 14 and the first sliding body 11 are installed together, they will not be easily separated.

[0082] It should be noted that the connection method of the first connection part 18 and the second connection part 19 is preferably a snap-fit ​​connection, which makes it difficult for the elastic member 3 to run out during installation, but it is not limited to the snap-fit ​​connection. There may only be a sliding fit relationship between the first connection part 18 and the second connection part 19, which makes the first slide body 11 move relative to the second slide body 12 without being separated from the second slide body 12. Similarly, the connection method of the third connection part 20 and the fourth connection part 21, and the connection method of the fifth connection part 22 and the sixth connection part 23 are preferably snap-fit ​​connections.

[0083] like Figure 1-Figure 2 , Figure 8-Figure 9 As shown, the brake pedal in the utility model also includes a third limiter 15, which is arranged between the pedal arm 1 and the pedal seat 2, and the third limiter 15 is arranged to avoid the bearing part. The third limiter 15 can limit the rotation angle of the pedal arm 1, thereby avoiding the problem that the pedal arm 1 rotates too much and accelerates the failure of the elastic member 3.
