[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The brake pedal assembly 100 according to an embodiment of the present invention is described below with reference to Figures 1 and 2.

[0027] As shown in Figure 1, the brake pedal assembly 100 according to an embodiment of the present invention includes: a pedal base 1, a pedal arm 2, and a connecting shaft 3.

[0028] Specifically, the pedal base 1 has a first connecting hole 12, and both ends of the connecting shaft 3 are inserted into the first connecting hole 12. The pedal arm 2 is connected to the connecting shaft 3. The connecting shaft 3 includes a first shaft segment 31 and a second shaft segment 32. Both the first shaft segment 31 and the second shaft segment 32 extend along a first direction. The axis of the first shaft segment 31 and the axis of the second shaft segment 32 are not collinear. Each end of the first shaft segment 31 is connected to a second shaft segment 32. The angle of the second shaft segment 32 is adjustable, and the distance between the axis of the first shaft segment 31 and the axis of the second shaft segment 32 in the radial direction is adjustable.

[0029] Understandably, the pedal base 1 serves as the fundamental support for the entire brake pedal assembly 100, ensuring the stability and safety of the pedal installation. The pedal base 1 has a first connecting hole 12 for mounting the connecting shaft 3. The radial distance between the first shaft segment 31 and the second shaft segment 32 can be adjusted via threads, gears, or other mechanical means, thereby changing the relative distance between them. The second shaft segment 32 passes through the first connecting hole 12. The pedal arm 2 is welded to the bushing 21 of the connecting shaft 3 and can rotate freely around the connecting shaft 3 to achieve the braking function. It should be noted that the radial distance refers to the distance in the radial direction between the axis of the first shaft segment 31 and the axis of the second shaft segment 32.

[0030] According to the embodiment of the present invention, the brake pedal assembly 100 adjusts the position of the pedal pivot 3 by adjusting the angle of the first shaft segment 31 and the radial distance between the first shaft segment 31 and the second shaft segment 32. This solves the problem of needing to open multiple pedal bases for different vehicle models due to different pivot positions. It is more convenient and can effectively prevent errors. It has no impact on the structure of surrounding parts and can be used in multiple different human-machine points and different leverage ratios, thus realizing the universality of the brake pedal assembly 100.

[0031] In some embodiments of this utility model, as shown in FIG2, the first shaft segment 31 has a first connecting segment 331 extending along a second direction perpendicular to the first direction, and the second shaft segment 32 has a second connecting segment 332 extending along a second direction perpendicular to the first direction. The first connecting segment 331 and the second connecting segment 332 are threadedly connected. It can be understood that both ends of the first shaft segment 31 have the first connecting segment 331, which extends along a second direction perpendicular to the first direction. The end of the second shaft segment 32 facing the first shaft segment 31 has the second connecting segment 332. The threaded connection of the first connecting segment 331 and the second connecting segment 332 enables precise length adjustment of the first shaft segment 31 and the second shaft segment 32 in the radial direction, thereby changing the distance between the first shaft segment 31 and the second shaft segment 32 in the radial direction. This improves the flexibility, precision, and stability of the brake pedal assembly 100, meeting the needs of different application scenarios and ergonomics.

[0032] In some embodiments of this utility model, the connecting shaft 3 further includes an adjusting member 34. The adjusting member 34 is disposed on the pedal base 1 and located at at least one end of the connecting shaft 3. The adjusting member 34 is configured to adjust the rotation angle of the connecting shaft 3. As shown in FIG2, the adjusting member 34 is disposed at the position of the first connecting hole 12. The adjusting member 34 is disposed at one end of one of the second shaft segments 32 away from the first shaft segment 31. By rotating the adjusting member 34, the rotation angle of the connecting shaft 3 relative to the pedal base 1 can be changed, thereby adjusting the initial position and stroke of the pedal arm 2. Thus, the adjusting member 34 and the second shaft segment 32 cooperate with each other to further improve the flexibility, accuracy and stability of the brake pedal assembly 100, thereby further meeting the needs of different application scenarios and ergonomics.

[0033] In some embodiments of this utility model, the adjusting member 34 is rotatably connected to the pedal base 1. A first limiting part is formed on the adjusting member 34, and a second limiting part is formed on the pedal base 1. The adjusting member 34 and the pedal base 1 are locked relative to each other by the cooperation of the first limiting part and the second limiting part. That is to say, the cooperation of the first limiting part and the second limiting part ensures both the accuracy of the rotation angle during the adjustment process and the stability of the adjusted angle, preventing changes during use.

[0034] Specifically, the first limiting part is formed as a locking tooth 341, and the second limiting part is formed as a locking groove, with the locking tooth 341 adapted to extend into the locking groove. As shown in the figure, the adjusting member 34 can be a gear, on which multiple locking teeth 341 are formed, each locking tooth 341 being adapted to the shape of the locking groove, thereby improving the stability and versatility of the brake pedal assembly 100.

[0035] In some other embodiments of this utility model, the first shaft segment 31 has a first connecting segment 331 extending along a second direction perpendicular to the first direction (as shown in Figure 2, the first direction and the second direction). The second shaft segment 32 has a second connecting segment 332 extending along the second direction perpendicular to the first direction. The first connecting segment 331 and the second connecting segment 332 are snap-fitted together. That is, the first connecting segment 331 and the second connecting segment 332 are sleeved together and the radial distance between the first shaft segment 31 and the second shaft segment 32 is adjusted by snap-fitting. This improves the stability, versatility and adjustment flexibility of the brake pedal assembly 100, and meets the needs of different application scenarios and ergonomics.

[0036] In some other embodiments of this utility model, one of the first connecting segment 331 and the second connecting segment 332 has a first engaging portion, and the other of the first connecting segment 331 and the second connecting segment 332 has a second engaging portion. The first connecting segment 331 and the second connecting segment 332 are engaged through the first engaging portion and the second engaging portion. That is to say, the engagement of the first connecting segment 331 and the second connecting segment 332 allows for flexible adjustment of the radial distance between the first shaft segment 31 and the second shaft segment 32, adapting to different human-machine point positions and lever ratio requirements, thereby achieving the universality of the brake pedal assembly 100.

[0037] Furthermore, one of the first and second engaging portions is formed as a latch, and the other of the first and second engaging portions is formed as multiple locking positions. The latch engages with one of the multiple locking positions to adjust the radial distance between the axis of the first shaft segment 31 and the axis of the second shaft segment 32. It can be understood that by the engagement of the latch and the multiple locking positions, the radial distance between the first shaft segment 31 and the second shaft segment 32 can be flexibly adjusted, achieving multiple radial distances between the first shaft segment 31 and the second shaft segment 32. This can solve the problem of different pivot positions caused by different human-machine positions and lever ratios.

[0038] Referring to Figures 1 and 2, a mounting groove 11 is formed on the pedal base 1. The top end of the pedal arm 2 is adapted to extend into the mounting groove 11 and connect with the first shaft segment 31. The depth and width of the mounting groove 11 should match the top end of the pedal arm 2 to ensure that the top end of the pedal arm 2 can be smoothly extended and fixed, which can ensure that the installation of the pedal arm 2 is more stable and precise.

[0039] In some embodiments of this utility model, the pedal base 1 has a first connecting hole 12, both ends of the connecting shaft 3 are inserted into the first connecting hole 12, the top end of the pedal arm 2 has a second connecting hole 22, the first shaft segment 31 is adapted to extend into the second connecting hole 22, a bushing 21 is provided between the first shaft segment 31 and the pedal arm 2, the bushing 21 is sleeved on the first shaft segment 31, and the pedal arm 2 is welded to the bushing 21 to ensure that the pedal arm 2 can rotate around the axis of the first shaft segment 31. Thus, by designing the mounting groove 11 and the second connecting hole 22, the installation of the pedal arm 2 is ensured to be more stable and precise, further improving the stability, versatility and adjustment flexibility of the brake pedal assembly 100.

[0040] The brake pedal assembly 100 according to two specific embodiments of the present invention will now be described with reference to Figures 1-2.

[0041] Example 1,

[0042] Specifically, as shown in Figures 1 and 2, the pedal base 1 has a first connecting hole 12. Both ends of the connecting shaft 3 pass through the first connecting hole 12. The pedal arm 2 is welded to the bushing 21 of the connecting shaft 3. The connecting shaft 3 includes a first shaft segment 31 and a second shaft segment 32, both of which extend along a first direction. The axis of the first shaft segment 31 is not collinear with the axis of the second shaft segment 32. Each end of the first shaft segment 31 is connected to a second shaft segment 32. The first connecting segment 331 and the second connecting segment 332 cooperate to adjust the radial distance between the axis of the first shaft segment 31 and the axis of the second shaft segment 32. The first connecting segment 331 and the second connecting segment 332 are threaded together.

[0043] The adjusting element 34 is a gear. The adjusting element 34 cooperates with the second shaft segment 32 to further improve the flexibility, precision, and stability of the brake pedal assembly 100, meeting the needs of different application scenarios and ergonomics. A mounting groove 11 is formed on the pedal base 1. The top end of the pedal arm 2 is adapted to extend into the mounting groove 11 and be welded to the bushing 21 of the first shaft segment 31. The depth and width of the mounting groove 11 should match the top end of the pedal arm 2 to ensure that the top end of the pedal arm 2 can smoothly extend and be fixed, ensuring a more stable and precise installation of the pedal arm 2. A second connecting hole 22 is formed at the top end of the pedal arm 2. The first shaft segment 31 is adapted to extend into the second connecting hole 22. A bushing 21 is provided between the first shaft segment 31 and the pedal arm 2 to ensure that the pedal arm 2 can rotate around the horizontal centerline of the first shaft segment 31.

[0044] Example 2,

[0045] This embodiment has a structure that is largely the same as that of Embodiment 1, with the same reference numerals used for the same components. The only difference is that in Embodiment 1, the distance between the axis of the first shaft segment 31 and the axis of the second shaft segment 32 in the radial direction is adjusted by a thread, while in this Embodiment 2, the distance between the axis of the first shaft segment 31 and the axis of the second shaft segment 32 in the radial direction is adjusted by a snap and multiple locking positions.
