Description

Technical Field

[0001] The utility model itself belongs to the technical field of automobile components, and specifically relates to an angle-adaptive brake pedal. Background Art

[0002] The brake pedal, as the name implies, is a pedal that limits power, that is, a foot brake pedal. The brake pedal is used to slow down and stop the car. It is one of the five major control parts for car driving. It is used very frequently. How the driver controls it directly affects the safety of car driving. A wheel or disc is fixed on the high-speed shaft of the machine, and a brake shoe, belt or disc corresponding to it is installed on the machine base, so that it generates a braking torque under the action of external force.

[0003] Patent CN118144907A discloses a braking system for motorcycles, including a rear brake arm, a transmission support, a brake coupling plate, a brake pump rocker arm, an adjustment mechanism and a rear brake, wherein the end of the rear brake arm cooperates with the transmission support, the transmission support is connected to the brake coupling plate via a fastener, the end of the brake coupling plate is connected to the brake pump rocker arm via a fastener, and the brake pump rocker arm is connected to the rear brake via a fastener, thereby forming a braking system; an adjustment mechanism is provided between the transmission support and the brake coupling plate.

[0004] In the above scheme, the rear brake arm and the rear brake are connected by a brake connecting plate, which replaces the traditional brake arm directly connected to the rear brake, so that it can save layout space and increase the adjustability of the brake system. However, the brake pedal and the brake arm are always performing the swing arm action. The outermost brake pedal begins to move in a curve driven by the brake arm, and its stepped surface also changes angle with the swing. The angle at which the driver presses the brake pedal is fixed regardless of whether it is a motorcycle or a car. Therefore, during the stroke of pressing the brake pedal, the fit between the brake pedal and the foot surface decreases due to the angle change, resulting in the driver's inability to control the brake pedal well. Utility Model Content

[0005] The purpose of the utility model is to provide an angle-adaptive brake pedal that can solve the above technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An angle-adaptive brake pedal comprises a curved rod and a pedal, wherein one side of the pedal is hingedly connected to one end of the curved rod so that the pedal can swing toward the other end of the curved rod, an elastic member is arranged on the curved rod, and the elastic member is connected to the hinge surface of the pedal, and adjustment sub-plates are arranged on both side surfaces of the pedal, and the adjustment sub-plates can be elastically bent toward one side of the curved rod.

[0008] In the angle-adaptive brake pedal, an oblique angle gap is provided on the end surface of the curved rod connected to the pedal, and the connecting surface of the pedal is hinged at the junction of the oblique angle gap and the end surface of the curved rod.

[0009] In the angle-adaptive brake pedal, one end of the elastic member is connected to the curved rod, and the other end of the elastic member is connected to the pedal connecting surface close to the bevel gap. The connecting surface of the pedal abuts against the end surface of the curved rod under the action of the elastic member.

[0010] In the angle-adaptive brake pedal, the pedal and the edge of the adjusting sub-plate close to the curved rod are connected by a hinge, and the elastic member is also connected to the hinged side of the pedal and the adjusting sub-plate, so that the side walls of the pedal and the adjusting sub-plate are pressed against each other.

[0011] In the angle-adaptive brake pedal, the elastic member includes a pedal spring sheet and a sub-plate spring sheet, the pedal spring sheet is arranged between the pedal and the curved rod, and the sub-plate spring sheet is connected between the pedal and the adjustment sub-plate on one side close to the curved rod.

[0012] In the angle-adaptive brake pedal, the elastic member includes at least two springs, one end of the spring is connected to the curved rod, and the other end of the spring is connected to a side of the adjusting sub-plate close to the curved rod.

[0013] In the angle-adaptive brake pedal, a spring fixing point is provided on each of the corresponding two side surfaces of the curved rod, and the spring fixing point is connected to the ends of the two springs, and the other ends of the two springs are respectively connected to the two ends of the adjustment sub-plate.

[0018] A hinge is used at the connection between the pedal and the crank arm, and a certain amount of damping is applied with an elastic member to achieve the function of adapting to the change in pedal angle caused by the swing of the crank arm when the pedal is pressed, and returning the pedal to its original angle after releasing the pedal. This allows the pedal to always fit completely with the driver's foot during the swing of the crank arm, preventing the pedal from slipping off the pedal due to insufficient contact surface.

[0019] The pedal is also equipped with an adjustable sub-plate that can be bent to both sides. Even if the pedal is pressed sideways, the adjustable sub-plate can bend to fit the instep of the foot and provide sufficient fulcrums, making the brake pedal more adaptable and ensuring driving safety.

[0023] The following are specific embodiments of the utility model and the accompanying drawings to further describe the technical solution of the utility model, but the utility model is not limited to these embodiments.

[0024] Example 1

[0025] like Figure 1-Figure 2 As shown, the angle-adaptive brake pedal comprises a crankshaft 1 and a pedal 2. One side of the pedal 2 is hinged to one end of the crankshaft 1 so that the pedal 2 can swing toward the other end of the crankshaft 1. An elastic member 3 is provided on the crankshaft 1. The elastic member 3 is connected to the hinge surface of the pedal 2. Adjustment sub-plates 21 are provided on both side surfaces of the pedal 2. The adjustment sub-plates 21 can be elastically bent toward one side of the crankshaft 1.

[0026] That is, a hinge is used at the connection between the pedal 2 and the crank arm 1, and a certain amount of damping is applied by an elastic member, so that the pedal 2 can adapt to the change in angle of the pedal 2 caused by the swing of the crank arm 1 when the pedal 2 is stepped on, and the pedal 2 can be restored to its original angle after the pedal 2 is released, so that the pedal 2 can always be completely in contact with the driver's foot during the swinging stroke of the crank arm 1, avoiding slipping off the pedal 2 due to insufficient contact surface.

[0027] At the same time, the pedal 2 is also provided with an adjustment sub-plate 21 that can be bent to both sides. Even if the pedal 2 is pressed sideways, the adjustment sub-plate 21 can be bent to fit the instep to provide sufficient fulcrums, making the brake pedal more adaptable and ensuring driving safety.

[0028] In this embodiment, an oblique angle gap 11 is provided on the end surface of the curved rod 1 connected to the pedal 2 , and the connecting surface of the pedal 2 is hinged at the junction of the oblique angle gap 11 and the end surface of the curved rod 1 .

[0029] An angled gap 11 of corresponding angle is provided according to the limit swing stroke of the crankshaft 1, so that the pedal 2 abuts against the end face of the crankshaft 1 when not stepped on, and abuts against the inclined surface of the angled gap 11 when stepped on to the bottom. The inclined surface of the angled gap 11 and the end face of the crankshaft 1 form the limit stop for the rotation of the pedal 2.

[0030] In this embodiment, one end of the elastic member 3 is connected to the curved rod 1, and the other end of the elastic member 3 is connected to the side of the pedal 2 connection surface close to the angled gap 11. The connection surface of the pedal 2 is abutted against the end surface of the curved rod 1 under the action of the elastic member 3.

[0031] The elastic member 3 is connected to one side of the angle between the angled gap 11 and the pedal 2. Whenever the pedal 2 is stepped on, the elastic member 3 is squeezed and deformed. When the pressure disappears, the pedal 2 is pushed back to the state of abutting against the end surface of the curved rod 1 by the elastic force.

[0032] Of course, the elastic member 3 may also be arranged on the other opposite side, and the pedal may be reset by utilizing the elastic force of the elastic member 3 deformed by tension.

[0033] In this embodiment, the pedal 2 and the adjusting sub-plate 21 are connected by a hinge at the edge close to the crank 1, and an elastic member 3 is also connected to the hinged side of the pedal 2 and the adjusting sub-plate 21 to make the side walls of the pedal 2 and the adjusting sub-plate 21 abut against each other.

[0034] The adjustment sub-plate 21 is set so that when the pedal is stepped on sideways, the adjustment sub-plate 21 can be bent to fit the foot surface to provide a larger contact surface, so that the driver can have better control. The elastic member 3 is also set on the adjustment sub-plate 21, so that the adjustment sub-plate 21 has a reset function, so as not to affect the contact angle with the pedal 2 when the pedal is stepped on forward next time.

[0035] Preferably, the elastic member 3 includes a pedal spring piece 31 and a sub-plate spring piece 32 . The pedal spring piece 31 is arranged between the pedal 2 and the curved rod 1 . The sub-plate spring piece 32 is connected between the pedal 2 and the adjusting sub-plate 21 on one side close to the curved rod 1 .

[0036] The spring piece is generally in the shape of a long arc, and the arched spring piece is used to provide elastic force to resist stepping on the pedal 2 and the adjusting sub-plate 21 so that they can return to their original positions.

[0037] In this embodiment, a splicing groove is provided on the treading surface of the pedal 2, an extension plate 22 is provided on one side of the adjusting sub-plate 21, and the extension plates 22 of the two adjusting sub-plates 21 are spliced ​​together in the splicing groove.

[0038] When the adjusting sub-plate 21 is not bent by being stepped on obliquely, the extended plates 22 on its side are spliced ​​in the splicing groove, and the left and right extended plates 22 each occupy half of the groove and are flush with the surface of the pedal 2 to maintain the foot feel when stepping on the front. When stepping on the pedal obliquely, the adjusting sub-plate 21 is bent and the extended plates 22 are brought out of the groove, so that the adjusting sub-plate 21 and the extended plates 22 together form a pedal surface with an area sufficient for the foot to step on, thereby achieving a solid foot feel at different angles.

[0039] Preferably, a plurality of anti-skid grooves 23 are provided on the treading surfaces of the adjusting sub-plate 21 and the extension plate 22 .

[0040] The anti-skid pattern 23 is provided to increase the friction between the pedal surface and the sole surface of the foot to prevent slipping when stepping on it.

[0041] In this embodiment, a rotating shaft connecting portion is provided at the other end of the curved rod 1, and a transmission connecting protrusion is provided on the rotating shaft connecting portion.

[0042] The bending angle of the crankshaft 1 can just avoid the pedaling foot, and can reduce the downward force during pedaling through the lever effect, so that the linkage components driven by the transmission connection protrusion can react more quickly.

[0043] Example 2

[0044] According to the technical solution of Example 1, the arrangement of the elastic member 3 is changed. The elastic member 3 includes at least two springs, one end of the spring is connected to the curved rod 1, and the other end of the spring is connected to the side of the adjusting sub-plate 21 close to the curved rod 1.

[0045] That is, the other end of the spring connected to the crankshaft 1 is fixed to the upper position of the adjusting sub-plate 21, that is, the spring supports the side of the pedal that swings, providing damping for the swing of the pedal when it is stepped on. At the same time, the position of the adjusting sub-plate 21 is wider than the crankshaft 1, and the spring extending from the crankshaft 1 is connected to the adjusting sub-plate 21 obliquely outward, so that the adjusting sub-plate 21 is supported by the spring elastic force when it is bent inward, so that the adjusting sub-plate 21 can return to a position flush with the pedal 2 after the pedal is released.

[0046] Usually in actual setting, a spring fixing point is set on each corresponding side surface of the curved rod 1, and the ends of two springs are installed on the spring fixing point. The other ends of the two springs are respectively connected to the upper and lower ends of the adjusting sub-plate 21 on the side where they are located.

[0047] When the pedal surface is stepped on and swung, the spring connected to the upper end of the adjusting sub-plate 21 is compressed, and the spring connected to the lower end is stretched. When the adjusting sub-plate 21 is stepped on obliquely and bent, the two upper and lower springs on this side are compressed together. In this way, when multiple spring supports are used, the movement of the pedal 2 and the adjusting sub-plate 21 is supported by springs at multiple points to ensure the stability of the trajectory.

[0048] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
