Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a brake pedal adjustment device, a brake pedal, and a vehicle. Background Technology

[0002] During vehicle operation, the driver converts the force applied by their foot into a hydraulic / pneumatic signal for the braking system by pressing the brake pedal, thereby slowing down or stopping the vehicle.

[0003] In real-world driving scenarios, different drivers have significantly different requirements for pedal force: professional racing drivers need heavier pedal force to achieve precise braking feedback, while older or female drivers prefer a lighter pedal feel; frequent light braking is required in congested urban traffic, while long-distance highway driving requires stronger brake pedal feedback force; the kinetic energy recovery system of new energy vehicles also places special demands on pedal force characteristics. Furthermore, different vehicle models' braking systems (hydraulic brakes / air brakes), brake assist methods (vacuum assist / electronic assist), and braking performance parameters (braking distance, braking force distribution) all impose differentiated requirements on the force transmission characteristics of the pedal mechanism.

[0004] The existing brake pedal has a fixed lever ratio and required input force curve, and the pedal force cannot be adjusted. The driver cannot change the feeling of the pedal when pressing it, which cannot meet the needs of some drivers who require heavy or light pedal force. Utility Model Content

[0005] This application provides a brake pedal adjustment device, a brake pedal, and a vehicle to solve the technical problem that the pedal force of existing brake pedals is not adjustable.

[0006] A first aspect of this application provides a brake pedal adjustment device, comprising:

[0008] The mounting base has an elastic component, and the other end of the pressure rod abuts against the elastic component. The pressure rod is configured to be driven by the pedal body to rotate about the hinge point of the pressure rod when the pedal body moves, so that the other end of the pressure rod compresses or releases the elastic component.

[0009] In one possible implementation, the mounting base is provided with a mounting limiting cavity and a pressing port, the elastic component is disposed in the mounting limiting cavity, and the pressing port communicates with the mounting limiting cavity;

[0010] A pressing plate is movably connected to the pressing port. One side of the pressing plate abuts against the pressing rod, and the other side of the pressing plate abuts against the elastic component.

[0012] A second limiting member is provided on the side of the pressing plate away from the pressing rod, and the other end of the elastic member abuts against the side of the pressing plate away from the pressing rod and is connected to the second limiting member.

[0013] In one possible implementation, the elastic element is a spring, the first limiting element is a first limiting protrusion that engages with the center hole at one end of the spring, and the second limiting element is a second limiting protrusion that engages with the center hole at the other end of the spring.

[0023] The aforementioned brake pedal is mounted on the vehicle body.

[0024] This application provides a brake pedal adjustment device, a brake pedal, and a vehicle. The brake pedal adjustment device has a pressure rod hinged to the pedal body, with the other end of the pressure rod abutting against an elastic component. When the driver presses down on the pedal body, the pressure rod is driven by the pedal body to rotate around the hinge point, causing the pressure rod to move with the pedal body and push the elastic component to produce compression deformation. At this time, the elastic component will generate an elastic reaction force, which is transmitted to the pedal body through the pressure rod, forming the pedal force. By increasing or decreasing the inherent elastic force of the elastic component, the pedal force of the pedal body can be adjusted. This adjustment mechanism breaks through the rigidity limitation of the traditional fixed lever ratio, allowing the vehicle to adapt to the different pedal feel needs of drivers (such as professional drivers needing heavy pedal force, while ordinary drivers prefer light pedal force). The brake pedal adjustment device of this application achieves personalized pedal feel configuration by increasing or decreasing the inherent elastic force of the elastic component without changing the original braking system structure, significantly improving the adaptability of the vehicle and the user's operating comfort.

[0051] During vehicle operation, the driver converts the force applied by their foot into a hydraulic / pneumatic signal for the braking system by pressing the brake pedal, thereby slowing down or stopping the vehicle.

[0052] The principle of the brake pedal is as follows: By applying force to the brake pedal surface (driver's foot pressure), the foot pressure is amplified by the fixed lever ratio structure formed between the pedal arm and the pin and transmitted to the push rod. The push rod is connected to the vacuum booster or foot valve. The hydraulic brake system amplifies the input force of the push rod through the vacuum booster to push the hydraulic master cylinder to push the fluid. The air brake system controls the opening and closing of the foot valve port through the push rod to transmit high-pressure gas. Finally, the pedal force is converted into driving braking force and transmitted to the brakes of the four wheels; that is, the driver's intention (to slow down) is converted into the physical action of the vehicle (braking).

[0053] Traditional brake pedals have fixed lever ratios and required input force curves, which cannot be adjusted, and drivers cannot change the amount of force they feel when pressing the pedal.

[0054] In real-world driving scenarios, different drivers have significantly different requirements for pedal force: professional racing drivers need heavier pedal force to achieve precise braking feedback, while older or female drivers prefer a lighter pedal feel; frequent light braking is required in congested urban traffic, while long-distance highway driving requires stronger brake pedal feedback force; the kinetic energy recovery system of new energy vehicles also places special demands on pedal force characteristics. Furthermore, different vehicle models' braking systems (hydraulic brakes / air brakes), brake assist methods (vacuum assist / electronic assist), and braking performance parameters (braking distance, braking force distribution) all impose differentiated requirements on the force transmission characteristics of the pedal mechanism.

[0055] The existing brake pedal has a fixed lever ratio and required input force curve, and the pedal force cannot be adjusted. The driver cannot change the feeling of the pedal when pressing it, which cannot meet the needs of some drivers who require heavy or light pedal force.

[0056] To address the technical problem of non-adjustable pedal force in existing brake pedals, this application proposes a brake pedal adjustment device, a brake pedal, and a vehicle. The brake pedal adjustment device includes a pressure rod and a mounting base. One end of the pressure rod is hinged to the pedal body. An elastic component is provided on the mounting base. The other end of the pressure rod abuts against the elastic component. The pressure rod is configured such that when the pedal body moves, it is driven by the pedal body to rotate about the hinge point of the pressure rod, so that the other end of the pressure rod compresses or releases the elastic component.

[0057] In the brake pedal adjustment device of this application, when the driver presses down on the pedal body, the pressure rod is driven by the pedal body to rotate around the hinge point of the pressure rod, causing the pressure rod to move with the pedal body to push the elastic component to produce compression deformation. At this time, the elastic component will generate elastic reaction force, which is transmitted to the pedal body through the pressure rod to form the pedal force. By increasing or decreasing the inherent elastic force of the elastic component, the magnitude of the pedal force of the pedal body can be adjusted. This adjustment mechanism breaks through the rigid limitation of the traditional fixed lever ratio, allowing the vehicle to adapt to the foot feel needs of different drivers (such as professional drivers needing heavy pedal force, while ordinary drivers prefer light pedal force). The brake pedal adjustment device of this application achieves personalized configuration of pedal feel by increasing or decreasing the inherent elastic force of the elastic component without changing the original braking system structure, significantly improving the adaptability of the vehicle and the user's operating comfort.

[0058] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0060] In the embodiments of this application, reference is made to Figures 1 to 4 As shown, an embodiment of this application provides a brake pedal adjustment device, including a pressure rod 100 and a mounting base 200.

[0061] One end of the pressure rod 100 is used to hinge with the pedal body 10.

[0062] An elastic component 300 is provided on the mounting base 200. The other end of the pressure rod 100 abuts against the elastic component 300. The pressure rod 100 is configured to be driven by the pedal body 10 to rotate about the hinge point of the pressure rod 100 when the pedal body 10 moves, so that the other end of the pressure rod 100 compresses or releases the elastic component 300.

[0063] In the brake pedal adjustment device of this application, the pedal body 10 is used by the driver to step on it to achieve vehicle braking, such as a floor-mounted brake pedal for passenger cars.

[0064] A conventional brake pedal mechanism includes a pedal body, a push rod 20, and a support connection structure 30.

[0065] One end of the pressure rod 100 is hinged to the pedal body 10. The pressure rod 100 is used to convert the movement of the pedal body 10 into a compression action on the elastic component 300.

[0066] The elastic component 300 is used to provide an adjustable counterforce. The elastic component 300 can be a spring, a rubber / polymer elastomer, a fluid elastic element, a composite elastic element, etc.

[0067] When the driver presses down on the pedal body 10, the pressure rod 100 is driven by the pedal body 10 to rotate around the hinge point of the pressure rod 100, so that the pressure rod 100 moves with the pedal body 10 to push the elastic component 300 to produce compression deformation; when the driver releases the pedal body 10, the elastic component 300 will reset, thereby pushing the pedal body 10 through the pressure rod 100, so that the pedal body 10 quickly resets.

[0068] In the brake pedal adjustment device of this application, when the driver presses the pedal body 10, the pressure rod 100 is driven by the pedal body 10 to rotate around the hinge point of the pressure rod 100, so that the pressure rod 100 moves with the pedal body 10 to push the elastic component 300 to produce compression deformation. At this time, the elastic component 300 will generate elastic reaction force, which is transmitted to the pedal body 10 through the pressure rod 100 to form pedal force. By increasing or decreasing the inherent elastic force of the elastic component 300, the pedal force of the pedal body 10 can be adjusted. This adjustment mechanism breaks through the rigidity limitation of the traditional fixed lever ratio, enabling the vehicle to adapt to the foot feel needs of different drivers (such as professional drivers needing heavy pedal force, and ordinary drivers preferring light pedal force). The brake pedal adjustment device of this application achieves personalized pedal feel configuration by increasing or decreasing the inherent elastic force of the elastic component 300 without changing the original braking system structure, significantly improving the adaptability of the vehicle and the user's operating comfort.

[0069] In other possible embodiments, refer to Figure 2 , Figure 3 and Figure 4 As shown, the mounting base 200 is provided with a mounting limiting cavity 210 and a pressing port 211. The elastic component 300 is disposed in the mounting limiting cavity 210, and the pressing port 211 is connected to the mounting limiting cavity 210. A pressing plate 400 is movably connected to the pressing port 211. One side of the pressing plate 400 abuts against the pressing rod 100, and the other side of the pressing plate 400 abuts against the elastic component 300.

[0070] In this embodiment, the mounting limiting cavity 210 can play a role in mounting and limiting the elastic unit 310. By setting the pressing plate 400, the force-bearing area between the pressing rod 100 and the elastic component 300 can be increased, making the force transmission more stable and smooth and continuous, and improving the stability of the elastic component 300 and the pedal body 10 under force.

[0071] In another embodiment, reference is made to Figure 3 , Figure 4 and Figure 6As shown, the elastic component 300 includes at least one elastic unit 310. The elastic unit 310 includes an elastic element 311 and a mounting plate 312. The mounting plate 312 is disposed in the mounting limiting cavity 210. A first limiting element 3121 is disposed on the mounting plate 312. One end of the elastic element 311 abuts against the mounting plate 312 and is connected to the first limiting element 3121.

[0072] A second limiting member 410 is provided on the side of the pressing plate 400 away from the pressing rod 100, and the other end of the elastic member 311 abuts against the side of the pressing plate 400 away from the pressing rod 100 and is connected to the second limiting member 410.

[0073] In this embodiment, the mounting limiting cavity 210 can install and limit the elastic unit 310, and the first limiting member 3121 and the second limiting member 410 further limit the elastic unit 310, avoiding the failure of force transmission caused by the movement offset of the elastic unit 310, and improving the stability of the elastic unit 310.

[0074] The first limiting member 3121 and the second limiting member 410 may be the same or different. For example, the first limiting member 3121 and the second limiting member 410 may be snap-fit ​​members, magnetic members, threaded connections, adhesive members, etc.

[0075] It should be noted that the number of elastic units 310 can be set to multiple, such as 1, 2, 3, etc. By setting different numbers of elastic units 310, the inherent elastic force of the entire elastic component 300 can be adjusted. Furthermore, the elastic coefficient of the elastic unit 310 can also be adjusted to adjust the inherent elastic force of the elastic component 300.

[0076] Furthermore, refer to Figure 5 and Figure 6 As shown, the mounting base 200 is provided with at least one mounting port 212, which corresponds to the mounting limiting cavity 210. Each elastic unit 310 is installed in the mounting limiting cavity 210 through the mounting port 212.

[0077] In this embodiment, the installation port 212 is provided to facilitate the assembly and disassembly of the elastic unit 310.

[0078] In some embodiments, reference is made to Figure 3 and Figure 4 As shown, the elastic element 311 is a spring, the first limiting element 3121 is a first limiting protrusion, the first limiting protrusion is engaged in the center hole at one end of the spring, and the second limiting element 410 is a second limiting protrusion, the second limiting protrusion is engaged in the center hole at the other end of the spring.

[0079] In this embodiment, the first limiting protrusion and the second limiting protrusion are respectively engaged in the center holes at both ends of the spring to limit the spring, avoid the failure of force transmission caused by the spring's movement deviation, and improve the stability of the spring.

[0080] In one embodiment, reference is made to... Figure 3 As shown, the mounting plate 312 has a limiting groove 3122 on the side away from the elastic member 311. A support plate 500 is provided in the mounting limiting cavity 210. At least one limiting protrusion 510 is provided on the support plate 500. Each limiting groove 3122 is correspondingly engaged with each limiting protrusion 510.

[0081] In this embodiment, a support plate 500 is provided in the mounting limiting cavity 210. The support plate 500 is used to support each mounting plate 312. The support plate 500 can be fixed to the inner wall of the mounting limiting cavity 210, or it can be set on the inner wall of the mounting limiting cavity 210 by snap-fit, bonding, welding or other methods. In this embodiment, the support plate 500 and the mounting limiting cavity 210 can be integrally formed.

[0082] The support plate is provided with at least one limiting protrusion 510. The mounting plate 312 is snapped into the limiting protrusion 510 through the limiting groove 3122, so as to realize the detachable connection of the mounting plate 312. This allows the elastic unit 310 to be easily disassembled, and the user can adjust the number of elastic units 310 in the mounting limiting cavity 210, thereby adjusting the pedal force of the brake pedal.

[0083] In one possible embodiment, refer to Figure 1 and Figure 2 As shown, the end of the pressing plate 400 away from the pedal body 10 is hinged to the pressing port 211, and the first hinge axis 420 of the pressing plate 400 is parallel to the second hinge axis 101 of the pressing rod 100.

[0084] In this embodiment, by hinged to the pressing port 211, the pressing plate 400 forms a cover plate for the pressing port 211 of the mounting limiting cavity 210, which protects the elastic component 300 inside the mounting limiting cavity 210 and prevents the pressing plate 400 from failing to transmit force due to movement offset, thereby improving the stability of the pressing plate 400 in transmitting force.

[0085] In some possible embodiments, refer to Figure 1 and Figure 2 As shown, the height of the end of the pressing plate 400 away from the pedal body 10 is higher than the height of the end of the pressing plate 400 close to the pedal body 10.

[0086] In this embodiment, since the height of the end of the pressing plate 400 away from the pedal body 10 is higher than the height of the end of the pressing plate 400 close to the pedal body 10, it is easier for the pressing rod 100 to press the elastic component 300, thereby increasing the pressing force of the pressing rod 100 on the elastic component 300.

[0087] Furthermore, the pressing plate 400 is parallel to the pedal body 10 before it is stepped on.

[0088] In this embodiment, by setting the pressing plate 400 parallel to the pedal body 10 before it is stepped on, the pressing force of the pressing rod 100 on the elastic component 300 can be further increased.

[0089] In another possible embodiment, refer to Figure 1 As shown, a roller 600 is provided at the end of the pressure rod 100 away from the pedal body 10, and the pressure rod 100 abuts against the pressing plate 400 through the roller 600.

[0090] In this embodiment, the pressure rod 100 abuts against the pressure plate 400 via the roller 600, thereby reducing the coefficient of friction between the pressure rod 100 and the pressure plate 400, facilitating the movement of the pressure rod 100 on the pressure plate 400, reducing wear and tear, and improving the service life of the brake pedal adjustment device of this application.

[0091] Furthermore, the elastic elements 310 are arranged at intervals along a first direction, wherein the first direction is perpendicular to the axis of the second hinge shaft 101 of the pressure bar 100.

[0092] In this embodiment, the rolling direction of the roller 600 is consistent with the arrangement direction of the elastic unit 310, so that the roller 600 can press on different elastic units 310 when rolling, thus ensuring the stability of the force.

[0093] Furthermore, refer to Figure 4 and Figure 6 As shown, it also includes a side support plate 800, which is disposed on the mounting plate 312 and is used to abut against the side wall of the elastic member 311.

[0094] In this embodiment, by adding a side support plate 800, the side support plate 800 plays a supporting and limiting role for the elastic element 311, avoiding the failure of force transmission caused by the movement offset of the elastic element 311, and further improving the stability of the elastic element 311.

[0095] Furthermore, refer to Figure 7As shown, the mounting plate 312 is provided with a first snap-fit ​​block 700, and the side support plate 800 is provided with a second snap-fit ​​block 900. The mounting plate 312 is snapped onto the inner wall of the mounting limiting cavity 210 by the first snap-fit ​​block 700, and the side support plate 800 is snapped onto the inner wall of the mounting limiting cavity 210 by the second snap-fit ​​block 900.

[0096] In this embodiment, both the mounting plate 312 and the side support plate 800 are detachably connected within the mounting limiting cavity 210, thereby facilitating the user's disassembly and assembly of the elastic unit 310 and the adjustment of the number of elastic units 310, thus improving the adaptability of the brake pedal adjustment device of this application.

[0097] A second aspect of this application provides a brake pedal, including a pedal body 10 and a brake pedal adjusting device according to any of the above embodiments, wherein the pressure rod 100 of the brake pedal adjusting device is hinged to the pedal body 10.

[0098] The brake pedal of this embodiment features a brake pedal adjustment device, which includes a lever 100 and a mounting base 200. One end of the lever 100 is hinged to the pedal body 10. An elastic component 300 is mounted on the mounting base 200, and the other end of the lever 100 abuts against the elastic component 300. The lever 100 is configured such that when the pedal body 10 moves, it is driven by the pedal body 10 to rotate around its hinge point, thereby compressing or releasing the elastic component 300 at the other end of the lever 100. In the brake pedal of this application, when the driver presses the pedal body 10, the lever 100 is driven by the pedal body 10 to rotate around its hinge point, causing the lever 100 to move with the pedal body 10 and push the elastic component 300 to compress and deform. At this time, the elastic component 300 generates an elastic reaction force, which is transmitted to the pedal body 10 through the lever 100, forming a pedal force. By increasing or decreasing the inherent elastic force of the elastic component 300, the pedal force of the pedal body 10 can be adjusted. This adjustment mechanism breaks through the rigidity limitation of the traditional fixed lever ratio, enabling the vehicle to adapt to the pedal feel needs of different drivers (such as professional drivers needing heavy pedal force, while ordinary drivers prefer light pedal force). The brake pedal adjustment device of this application achieves personalized pedal feel configuration by increasing or decreasing the inherent elastic force of the elastic component 300 without changing the original braking system structure, significantly improving the adaptability of the vehicle and the user's operating comfort.

[0099] A third aspect of this application provides a vehicle, including a vehicle body and a brake pedal as described in the above embodiment, the brake pedal being disposed on the vehicle body.

[0100] The vehicle in this embodiment has a brake pedal, and the lever 100 of the brake pedal adjustment device is hinged to the pedal body 10. When the driver presses the pedal body 10, the lever 100 is driven by the pedal body 10 to rotate around the hinge point of the lever 100, causing the lever 100 to move with the pedal body 10 to push the elastic component 300 to produce compression deformation. At this time, the elastic component 300 will generate an elastic reaction force, which is transmitted to the pedal body 10 through the lever 100 to form the pedal force. By increasing or decreasing the inherent elastic force of the elastic component 300, the pedal force of the pedal body 10 can be adjusted. This adjustment mechanism breaks through the rigidity limitation of the traditional fixed lever ratio, allowing the vehicle to adapt to the different pedal feel needs of drivers (such as professional drivers needing heavy pedal force, while ordinary drivers prefer light pedal force). The brake pedal adjustment device of this application, without changing the original braking system structure, achieves personalized pedal feel configuration by increasing or decreasing the inherent elastic force of the elastic component 300, significantly improving the adaptability of the vehicle and the user's operating comfort.
