[0031] Reference Figures 1 to 3 , showing a schematic structural diagram of a brake pedal assembly according to an embodiment of the present application, the brake pedal assembly may specifically include: a mounting frame 10, a pedal arm 20 and an adjustment component;

[0032] The upper end of the pedal arm 20 is rotatably connected to the mounting frame 10 via a rotating shaft 11;

[0033] The pedal arm 20 is connected to the vacuum booster push rod through the adjustment assembly;

[0034] The pedal arm 20 is provided with a plurality of mounting holes 21 , one end of the adjustment component is connected to the vacuum booster push rod, and the other end of the adjustment component is connected to one of the plurality of mounting holes 21 to adjust the lever ratio of the brake pedal assembly.

[0035] In the embodiment of the present application, the other end of the adjustment assembly can be connected to different mounting holes 21, so that the pedal arm 20 and the vacuum booster push rod have different spacings, and the pedal arm 20 and the mounting frame 10 have different angles, so that the brake pedal assembly can obtain different lever ratios and have a variety of pedal feelings. Therefore, the lever ratio of the brake pedal assembly can be adjusted according to different vehicle models and different user habits, so that the brake pedal assembly can be compatible with a variety of different vehicle models, and has a simple structure, convenient and fast operation, and is safe and reliable, shortening the vehicle development cycle and reducing production costs.

[0036] For example, in an embodiment of the present application, the mounting hole 21 can be arranged on the pedal arm 20 near the rotating shaft 11 between the pedal arm 20 and the mounting frame 10, so that when the other end of the adjustment component is connected to the mounting holes 21 at different positions, since the multiple mounting holes 21 are distributed close to the rotating shaft 11, the lever ratio of the brake pedal assembly has a better adjustment effect.

[0037] In the embodiment of the present application, for example, the mounting frame 10 is used to provide mounting support, and the pedal arm 20 is rotatably connected to the mounting frame 10. When braking is required, the pedal arm 20 rotates close to the mounting frame 10, driving the adjustment component to press the vacuum booster push rod, and then the vacuum booster push rod drives the vacuum booster to brake. For example, the pedal arm 20 can be rotatably connected to the mounting frame 10 through a rotating shaft and an elastic member, etc. The embodiment of the present application does not limit the specific connection method between the mounting frame 10 and the pedal arm 20.

[0038] Specifically, in an embodiment of the present application, the brake pedal assembly also includes a pedal body, which is connected to one end of the pedal arm 20 away from the mounting frame 10. The pedal body can be a planar structure. The driver can use the pedal body to step on the brake pedal assembly and make the pedal body drive the pedal arm 20 to rotate toward the mounting frame 10.

[0039] In the prior art, the brake pedal assembly is usually made of sheet metal stamping and welding. The process requires the sheet metal mold and the pedal arm 20 mold to be made first. After the brake pedal lever ratio is determined, the position of the pedal surface cannot be changed due to the pedal body. The lever ratio needs to be changed for different models, so the sheet metal mold and the brake pedal arm 20 need to be redeveloped, which has a long assembly development cycle and high development costs. However, the present application can adjust the lever ratio of the brake pedal assembly through an adjustment component, which is simple and convenient to operate. There is no need to redevelop the sheet metal mold and the brake pedal arm 20, which can be reused, shortening the vehicle development cycle and reducing production costs.

[0040] For example, in an embodiment of the present application, the number of mounting holes 21 can be 2, 3 or 4, etc., and the intervals between the multiple mounting holes 21 are set, wherein the spacing between two adjacent mounting holes 21 can be the same or different, and can be set according to actual needs. The embodiment of the present application does not limit the specific number and setting method of the mounting holes 21.

[0041] Optionally, in the embodiment of the present application, the adjustment assembly includes an adjustment seat 32 and a connecting member 33; one end of the adjustment seat 32 is movably connected to the vacuum booster push rod, the other end of the adjustment seat 32 is movably connected to the connecting member 33, and the end of the connecting member 33 away from the adjustment seat 32 is connected to one of the multiple mounting holes 21. In this way, the adjustment assembly is movably connected to the vacuum booster push rod through the adjustment seat 32, and the adjustment assembly is connected to the mounting hole 21 on the pedal arm 20 through the connecting member 33. One end of the adjustment seat 32 is movably connected to the vacuum booster push rod, and the other end of the adjustment seat 32 is connected to the connecting member 33. By adjusting the size between the adjustment seat 32 and the vacuum booster push rod, the adjustment assembly can adjust the height of the pedal surface of the pedal body connected to the pedal arm 20, so that the pedal body has a pedal surface of a suitable height to meet the installation requirements of the brake pedal assembly on the vehicle. The human-machine position of the pedal surface remains unchanged or the human-machine position is adjusted more appropriately.

[0042] Optionally, in an embodiment of the present application, the internal opening of the adjustment seat 32 is provided with a threaded structure, and the threaded structure is respectively threadedly connected to the vacuum booster push rod and the connecting member 33 to adjust the length of the adjustment assembly. Specifically, the adjustment seat 32 can be rotated clockwise or counterclockwise through the threaded structure, so that the vacuum booster push rod and the connecting member 33 extend from the opening of the adjustment seat 32, thereby adjusting the length of the adjustment assembly to increase. Alternatively, the adjustment seat 32 can be rotated in the opposite direction through the threaded structure, so that the vacuum booster push rod and the connecting member 33 shrink into the opening of the adjustment seat 32, thereby adjusting the length of the adjustment assembly to decrease. As a result, the vacuum booster push rod and the connecting member 33 are telescopically connected to the two ends of the adjustment seat 32, realizing a movable connection between the adjustment seat 32 and the vacuum booster push rod and the connecting member 33.

[0043] In some optional embodiments of the present application, the adjustment assembly may further include a connecting rod 31, one end of which is connected to the vacuum booster push rod, and the other end of which is threadedly connected to the threaded structure of the adjustment seat 32. In this way, the connection between the adjustment seat 32 and the vacuum booster push rod is achieved through the connecting rod 31, which is convenient for assembly and adjustment. Specifically, in an embodiment of the present application, the connecting rod 31 is connected between the vacuum booster push rod and the adjustment seat 32, and the other end of the connecting rod 31 is telescopically connected to the opening through a threaded structure, and the length of the adjustment assembly is adjusted by the telescopic connection between the connecting rod 31 and the adjustment seat 32. That is, the movable connection between the connecting rod 31 and the adjustment seat 32 is achieved by the telescopic connection between the other end of the connecting rod 31 and the opening of the adjustment seat 32, and then the spacing between the connecting rod 31 and the adjustment seat 32 is adjusted to achieve the dimensional adjustment of the length of the adjustment assembly. For example, the elastic member may also be used to drive one end of the connecting rod 31 to engage with engaging positions at different positions in the opening, thereby realizing a telescopic connection between the connecting rod 31 and the opening, which is not limited in the embodiment of the present application.

[0044] Optionally, in the embodiment of the present application, the other end of the connecting rod 31 may be provided with a first thread structure, and the inner wall of the opening near the connecting rod 31 may be provided with a second thread structure, and the first thread structure is threadedly connected to the second thread structure. In this way, by rotating the adjustment seat 32 or the connecting rod 31, the first thread structure and the second thread structure can be engaged with each other and slidably connected, so that the connecting rod 31 can be rotated to extend into the adjustment seat 32 or rotated out of the adjustment seat 32, thereby adjusting the size of the connecting rod 31 and the adjustment seat 32 in the axial direction. Therefore, through the threaded connection of the first thread structure and the second thread structure, the accuracy and reliability of the telescopic adjustment between the connecting rod 31 and the adjustment seat 32 are improved.

[0045] In the embodiment of the present application, optionally, a third thread structure is provided at one end of the connecting member 33 close to the adjusting seat 32, a fourth thread structure is provided at one side of the opening close to the connecting member 33, and the third thread structure is threadedly connected to the fourth thread structure. In this way, a relatively stable and reliable connection between the adjusting seat 32 and the connecting member 33 is achieved through the threaded connection between the third thread structure and the fourth thread structure.

[0046] For example, in the embodiment of the present application, the connecting member 33 includes a connecting portion 331 and a shift fork 332 connected to the connecting portion 331, the connecting portion 331 is threadedly connected to the threaded structure in the opening of the adjustment seat 32, and the shift fork 332 is connected to one of the multiple mounting holes 21. In this way, the threaded connection between the connecting member 33 and the adjustment seat 32 is realized by the connecting portion 331, and the connection between the connecting member 33 and the mounting hole 21 is realized by the shift fork 332. Specifically, the outer wall of the connecting portion 331 is provided with a thread ring, and the thread ring is engaged with the thread structure in the opening of the adjustment seat 32 to realize the threaded connection. When the adjustment seat 32 is rotated, the thread structure and the thread ring move relative to each other so that the connecting portion 331 extends out or retracts from the opening of the adjustment seat 32.

[0047] Optionally, in the embodiment of the present application, the adjustment component further includes a locking member 34, the locking member 34 is sleeved on the connecting portion 331, and is threadedly connected to the outer periphery of the adjusting seat 32 and the connecting portion 331. In this way, by rotating the locking member 34, the locking member 34 is respectively connected to the adjusting seat 32 and the connecting member 33, and the connecting member 33 is locked on the adjusting seat 32, so as to further enhance the connection reliability and stability between the adjusting seat 32 and the connecting member 33, and avoid shaking or slipping of the connecting member 33. Specifically, the locking member 34 can be threadedly connected to the third thread structure of the connecting member 33. For example, the locking member 34 can be a locking nut, and the embodiment of the present application does not limit the specific type of the locking member 34.

[0048] Optionally, in the embodiment of the present application, the adjustment assembly further includes a fastener, the shift fork 332 includes a first paddle and a second paddle, the first paddle and the second paddle are connected to the connecting portion 331, the first paddle and the second paddle are respectively clamped on both sides of the pedal arm 20, and the first paddle and the second paddle are provided with a connecting hole 36, and the fastener passes through the connecting hole 36 and the mounting hole 21 in sequence. In this way, the connection between the shift fork 332 and the pedal arm 20 is realized by the fastener, the connection reliability and stability between the two are improved, the operation is simple, and it is easy to realize. And the first paddle and the second paddle can have good connection reliability and tightness on both sides of the pedal arm 20.

[0049] For example, in the embodiments of the present application, the fasteners may be bolts, studs, screws or screws, etc., which may be configured according to actual needs. The embodiments of the present application may not limit the specific types of fasteners.

[0050] In the embodiment of the present application, optionally, the adjustment assembly further includes an adapter plate 35, one end of which is connected to the vacuum booster push rod, and the other end of which is connected to the connecting rod 31, and the adapter plate 35 extends away from the rotating shaft 11 between the pedal arm 20 and the mounting frame 10. In this way, the connection between the vacuum booster push rod and the connecting rod 31 is achieved through the adapter plate 35, which facilitates the arrangement of the adapter plate 35 according to the position of the vacuum booster push rod, so that the adjustment assembly as a whole has a better stress transfer effect, avoids the connecting rod 31 directly connected to the vacuum booster push rod and easily generates shear force to cause fracture damage, and improves the structural stability of the adjustment assembly.

[0051] In the embodiment of the present application, specifically, the vacuum booster push rod is arranged below the rotating shaft 11 between the mounting frame 10 and the pedal arm 20, and the distance between the vacuum booster push rod and the rotating shaft 11 is relatively close, resulting in a relatively small space between the vacuum booster push rod and the pedal arm 20. If the vacuum booster push rod is directly connected to the connecting rod 31, it is easy to cause the adjustment range of the distance between the vacuum booster push rod and the pedal arm 20 by the adjustment component to be relatively small, resulting in a poor adjustment effect of the lever ratio of the brake pedal assembly by the adjustment component. Therefore, the transfer connection between the vacuum booster push rod and the connecting rod 31 is realized by setting an adapter plate 35, and the adapter plate 35 is arranged to extend downward away from the rotating shaft 11 between the pedal arm 20 and the mounting frame 10. Since there is a relatively large space below the side of the pedal arm 20 and the mounting frame 10 away from the rotating shaft 11, the adjustment component has a relatively large setting space, and then the adjustment component can have a relatively large adjustment range for the distance between the vacuum booster push rod and the pedal arm 20, thereby achieving a relatively good lever ratio adjustment effect on the brake pedal assembly.

[0052] Specifically, in the embodiment of the present application, the adapter plate 35 extends away from the rotation axis between the pedal arm 20 and the mounting frame 10, that is, the adapter plate extends downward in the space between the pedal arm 20 and the mounting frame 10, so that the adjustment component has a better adjustment effect on the distance between the vacuum booster push rod and the pedal arm, and achieves a better lever ratio adjustment effect on the brake pedal assembly. In addition, there is a large space on the side away from the rotation axis between the pedal arm 20 and the mounting frame 10, which is also convenient for arranging the adapter plate and other structures of the adjustment component, and also has a more reasonable spatial structure layout.

[0053] For example, in an embodiment of the present application, a locking nut can also be used to fix the adapter plate 35 to the vacuum booster push rod, thereby improving the connection stability of the adapter plate 35 and further enhancing the connection reliability and stability between the adjustment component and the vacuum booster.

[0054] In the embodiment of the present application, for example, the adapter plate 35 extends along a first direction, and the connecting rod 31 extends along a second direction, and the first direction is set at an angle to the second direction. The second direction can be the axial direction of the connecting rod 31, and the adapter plate 35 extends in a direction that is angled with the axial direction of the connecting rod 31. In this way, since the adapter plate 35 is fixedly connected to the vacuum booster push rod, when the connecting rod 31 rotates relative to the adjustment seat 32, the connecting rod 31 drives the adapter plate 35 to rotate and cause deviation, and it is also avoided that the connecting rod 31 and the adjustment seat 32 are easily slipped due to rotation after assembly, resulting in unstable size fixation of the adjustment component. In addition, it is also convenient to set the setting position of the adapter plate 35 and the connecting rod 31 according to the layout of the whole vehicle, so as to improve the convenience of installation. For example, the angle between the first direction and the second direction can be 90°, 80° or 100°, etc., which can be set according to actual installation needs. The embodiment of the present application does not limit the angle between the first direction and the second direction.

[0058] For example, in an embodiment of the present application, the brake pedal assembly of the braking system can be connected to the master cylinder via a brake booster. When the user presses the brake pedal of the brake pedal assembly, the booster rod pushes the booster or the master cylinder to move the piston in the master cylinder.
