Technical Field

[0001] This utility model relates to automotive braking systems, and more specifically, to a brake pedal assembly and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, the braking system, as an important component of vehicle safety performance, is receiving increasing attention for its reliability and comfort. Within the automotive braking system, the brake pedal assembly is a key component connecting the driver's operation with the braking actuator, and the ball joint bayonet structure is a crucial link in connecting the brake pedal to the booster pushrod.

[0003] In common brake pedal assemblies on the market, the ball joint mount and ball joint bracket are connected by a limit snap-fit ​​during the vehicle design, development, and after-sales maintenance process and cannot be disassembled. It is necessary to break and disassemble the ball joint mount to disconnect the connection between the brake pedal and the booster push rod. The ball joint mount cannot be reused and is inconvenient for maintenance.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a brake pedal assembly and vehicle. This utility model has a simple structure, is easy to disassemble and assemble, and improves maintenance efficiency.

[0006] The aforementioned detachable ball joint mount for an automotive braking system includes a brake pedal assembly and a ball joint structure assembly that mates with the brake pedal assembly. The ball joint structure assembly includes a ball joint bracket, a limiting bracket, and a ball joint buckle. The ball head seat bracket has a ball head groove on one side, and a bolt is fixedly connected to the bottom of the ball head groove. Limiting plates are fixedly connected to the upper two ends of the opening of the ball head groove. The limiting bracket has an "n" shaped structure and a through hole in the middle. Limiting plates are fixedly connected to the two long ends of the limiting bracket on the same side. The ball head seat buckle has a ball head fixedly connected to one end, and limiting protrusions are fixedly connected to the ball head seat buckle on both sides of the ball head.

[0007] Preferably, the ball head enters the ball head groove and abuts against the inside of the ball head groove. The two limiting plates on the limiting bracket are located at both ends of the ball head seat buckle and abut against the limiting protrusion. The bolt on the ball head seat bracket passes through the through hole on the limiting bracket. A nut is threaded onto the bolt, and one side of the nut abuts against the limiting bracket.

[0008] Preferably, the brake pedal assembly includes a brake pedal base, one end of which is fixedly connected to a brake pedal shaft, a brake pedal arm is rotatably connected to the brake pedal shaft, one end of which is fixedly connected to a brake pedal surface, and a plate arm groove is formed on the brake pedal arm facing the brake pedal base.

[0009] Preferably, the plate arm groove is fixedly connected to the ball head seat bracket.

[0010] Preferably, the sum of the width of the limiting protrusion and the width of the limiting insert is equal to the length of the limiting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves the limiting and fixing of the ball head seat by adding a limiting bracket to the ball head seat bracket and fixing it to the ball head seat bracket with a nut. This allows the ball head seat bayonet to be separated from the ball head seat bracket by removing the limiting bracket, which greatly improves the maintainability and reusability of the ball head seat bayonet and solves the problem that the ball head seat bayonet cannot be removed and requires destructive disassembly in the prior art. 2. The limiting bracket design of this utility model simplifies the structure, reduces the number of parts, lowers production costs, and improves assembly efficiency, making the brake pedal structure more compact and solving the problem of numerous parts and complex structure in the prior art; the limiting and fixing connection between the ball joint seat and the ball joint seat bracket reduces the fitting gap between parts during braking, effectively reducing impact noise during braking and improving driving comfort.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] Example 1 like Figure 1 As shown, a detachable ball joint mount for an automotive braking system includes a brake pedal assembly 1 and a ball joint structure assembly 2 that mates with the brake pedal assembly 1. Figure 6 As shown, the brake pedal assembly 1 includes a brake pedal base 101. A brake pedal shaft 102 is fixedly connected to one end of the brake pedal base 101. A brake pedal arm 103 is rotatably connected to the brake pedal shaft 102. A brake pedal surface 104 is fixedly connected to one end of the brake pedal arm 103. A plate arm groove 1031 is formed on the side of the brake pedal arm 103 facing the brake pedal base 101. The plate arm groove 1031 is fixedly connected to a ball joint bracket 201. This structural design allows the brake pedal arm 103 to rotate around the brake pedal shaft 102. When the driver presses the brake pedal surface 104, the brake pedal arm 103 drives the ball joint assembly 2 to move together, thereby achieving the braking function.

[0016] like Figure 2 As shown, the ball joint assembly 2 includes a ball joint seat bracket 201, a nut 202, a limiting bracket 203, and a ball joint seat buckle 204. The ball joint seat bracket 201 is fixedly connected to the plate arm groove 1031 on the brake pedal arm 103, providing a supporting foundation for the entire ball joint assembly 2.

[0017] like Figure 3As shown, a ball joint bracket 201 has a ball joint groove 2012 on one side, and a bolt 2011 is fixedly connected to the bottom of the ball joint groove 2012. Limiting plates 2013 are fixedly connected to the upper two ends of the opening of the ball joint groove 2012. The ball joint groove 2012 is used to accommodate the ball joint 2041 on the ball joint buckle 204, and the limiting plates 2013 play a role in limiting the ball joint buckle 204 to prevent the ball joint buckle 204 from lateral displacement during operation.

[0018] like Figure 4 As shown, the limiting bracket 203 has an "n"-shaped structure. A through hole 2031 is provided in the middle of the limiting bracket 203, and limiting insert plates 2032 are fixedly connected to the two long ends of the limiting bracket 203 on the same side. The limiting bracket 203 engages with the bolt 2011 on the ball joint bracket 201 through the through hole 2031, while the limiting insert plate 2032 engages with the limiting protrusion 2042 on the ball joint buckle 204, together achieving the fixation and limiting of the ball joint buckle 204.

[0019] like Figure 5 As shown, a ball head 2041 is fixedly connected to one end of the ball head seat buckle 204. Limiting protrusions 2042, which are fixedly connected to the ball head seat buckle 204, are provided on both sides of the ball head 2041. The ball head 2041 enters the ball head groove 2012 and abuts against the inside of the groove. Two limiting plates 2032 on the limiting bracket 203 are located at both ends of the ball head seat buckle 204, and the limiting plates 2032 abut against the limiting protrusions 2042. A bolt 2011 on the ball head seat bracket 201 passes through the through hole 2031 on the limiting bracket 203. A nut 202 is threaded onto the bolt 2011, and one side of the nut 202 abuts against the limiting bracket 203. The sum of the width of the limiting protrusion 2042 and the width of the limiting plate 2032 is equal to the length of the limiting plate 2013. This dimensional fit ensures that the ball head seat buckle 204 will not wobble after installation, improving the stability of the connection.

[0020] like Figure 1 As shown, after the entire device is assembled, the brake pedal assembly 1 is connected to other parts of the braking system via the ball joint structure assembly 2. The ball joint 2041 on the ball joint seat buckle 204 is firmly fixed in the ball joint groove 2012. Through the cooperation of the limiting bracket 203, the limiting insert 2032 and the limiting protrusion 2042, as well as the tightening action of the bolt 2011 and the nut 202, a stable and reliable connection structure is formed.

[0021] The working principle of this detachable ball joint latch is as follows: When the driver presses the brake pedal surface 104, the force is transmitted to the ball joint assembly 2 through the brake pedal arm 103. The ball head 2041 on the ball joint latch 204 moves accordingly within the ball head groove 2012. Due to the action of the limiting bracket 203 and the limiting plate 2013, the movement of the ball head 2041 is limited to a certain range, ensuring the stability and reliability of the braking system. Furthermore, due to the detachable design, when maintenance or replacement of parts is required, simply loosen the nut 202 and remove the limiting bracket 203 to easily disassemble the ball joint latch 204, greatly improving the convenience of maintenance.

[0022] This utility model also provides a vehicle including a brake pedal assembly with the aforementioned mechanism. The specific structure of this brake pedal assembly can be found in [reference needed]. Figures 1 to 6 Since the vehicle of this utility model includes the brake pedal assembly in the above embodiments, it has all the advantages of the above brake pedal assembly.

[0023] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
