Description

Technical Field

[0001] This utility model relates to the field of automotive safety technology, specifically to a brake pedal structure and vehicle that optimizes collision safety. Background Technology

[0002] Vehicle crash testing has always been an important topic in the field of automotive safety technology. Its purpose is to ensure that the airbags in the driver's cab deploy at the optimal position and angle in the event of a collision to protect the driver's safety. Therefore, there are strict requirements for the displacement of the steering wheel center point in vehicle crash testing.

[0003] According to the existing cockpit layout, in the event of a 40% offset collision, the impact object may compress the shock absorber mounting base, and the deformation of the mounting base may compress the vacuum booster. The vacuum booster is connected to the brake pedal, causing the brake pedal to undergo a large displacement. Since the brake pedal is located under the steering column, a traditional brake pedal may push against the steering column, causing the steering column, steering wheel, and airbag to undergo large displacement and angle changes. When the airbag deploys, it cannot effectively protect the driver.

[0004] In existing technologies, an anti-intrusion structure is typically installed on the steering column to limit the rise of the brake pedal during a collision, preventing the brake pedal from directly colliding with the steering column. Essentially, the anti-intrusion structure absorbs the kinetic energy of the brake pedal, preventing it from rising and colliding directly with the steering column, thus protecting the driver. However, in an actual collision, the brake pedal's structure may be instantly destroyed upon impact with the anti-intrusion structure, potentially causing direct injury to the driver's legs. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a brake pedal structure and vehicle that optimizes collision safety. By optimizing the structure of the brake pedal, the effect of the collision between the brake pedal and the steering column during a vehicle collision is improved, thereby reducing the displacement and angle changes of the steering column, steering wheel, and airbag, so that the airbag is in the optimal position and angle when it deploys, thus protecting the driver's safety; at the same time, it can also reduce the possibility of the brake pedal being damaged, and prevent the damaged structure from directly injuring the driver's legs.

[0006] The technical solution of this utility model is: a brake pedal structure for optimizing collision safety, comprising:

[0007] The bracket body includes a left mounting bracket and a right mounting bracket arranged symmetrically on the left and right sides, and the left mounting bracket is provided with a guide plate.

[0008] A rotating shaft, the two ends of which are respectively connected to the left mounting bracket and the right mounting bracket;

[0009] The pedal wall is rotatably connected to the rotating shaft.

[0015] According to the present invention, a brake pedal structure for optimizing collision safety is provided, wherein the base of the left mounting bracket is provided with multiple mounting holes.

[0016] According to the present invention, a brake pedal structure for optimizing collision safety is provided, wherein the base of the right mounting bracket is provided with multiple mounting holes.

[0017] According to the present invention, there is an optimized brake pedal structure for collision safety, wherein the pedal wall is a solid structure.

[0018] According to the present invention, a brake pedal structure for optimizing collision safety is provided, which also includes a brake light switch bracket, wherein the brake light switch bracket is connected to the bracket wall of the right mounting bracket.

[0019] Based on the same inventive concept, this utility model also provides a vehicle, which includes a brake pedal structure for optimized collision safety as described above.

[0020] The advantages of this application are:

[0021] 1. In the event of a 40% offset collision, this utility model can change the direction of the brake pedal's movement toward the steering column caused by the collision, thereby avoiding a frontal collision between the brake pedal and the steering column.

[0037] This utility model relates to a brake pedal structure that optimizes collision safety. By optimizing the structure and improving the elasticity of the snap-fit ​​structure, the snap-fit ​​connecting plate becomes more stable, has a longer service life, and is less prone to fatigue failure even after repeated disassembly and assembly.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] A brake pedal structure for optimized collision safety, specifically, such as Figure 1 As shown, it includes:

[0040] The main body of the bracket includes a left mounting bracket 1 and a right mounting bracket 2 arranged symmetrically on the left and right sides. The left mounting bracket 1 is provided with a guide plate 11.

[0041] Rotating shaft 4, with its two ends connected to left mounting bracket 1 and right mounting bracket 2 respectively;

[0042] The pedal wall 5 is rotatably connected to the rotating shaft 4.

[0043] One end of the left mounting bracket 1 is used to connect to the front bulkhead of the vehicle, and the other end is connected to the rotating shaft 4. When the car is involved in a 40% offset collision, the end of the left mounting bracket 1 connected to the rotating shaft 4 will collide with the steering column. This utility model provides a guide plate 11 at the end of the left mounting bracket 1 connected to the rotating shaft 4, which can change the movement direction of the left mounting bracket 1 and avoid the left mounting bracket 1 from directly colliding with the steering column, causing the steering column, steering wheel and airbag to have large displacement and angle changes, so that the airbag cannot protect the driver well when it deploys.

[0044] Specifically, the guide plate 11 includes an arc-shaped curved surface structure. When the left mounting bracket 1 collides with the steering column, the guide plate 11 can guide the left mounting bracket 1 to move in the tangential direction of the arc-shaped curved surface structure of the guide plate 11, reducing the impact on the steering column and preventing the steering column, steering wheel, and airbag from undergoing large displacement and angle changes, thereby ensuring that the driver's head can be protected when the airbag is deployed.

[0045] In some embodiments, the left mounting bracket 1 described above has been optimized, specifically, as follows: Figure 2 As shown, the left mounting bracket 1 includes a base and a bracket wall. The base is used to connect to the front bulkhead of the vehicle. The bracket wall includes a connecting part with a connecting hole. The rotating shaft 4 connects the left mounting bracket 1 and the right mounting bracket 2 through the connecting hole.

[0046] Specifically, in this embodiment, the base of the left mounting bracket 1 is angled to the bracket wall, which increases the connection area between the left mounting bracket 1 and the front panel of the vehicle, ensuring the connection strength between the left mounting bracket 1 and the front panel of the vehicle, and preventing the bracket body from falling off the front panel of the vehicle when the car collides, so that the brake pedal directly impacts and injures the driver's legs.

[0047] In fact, the guide plate 11 is connected to the edge of the bracket wall connection. On the one hand, the guide plate 11 can guide the movement direction of the left mounting bracket 1 and prevent the left mounting bracket 1 from colliding directly with the steering column. On the other hand, the guide plate 11 can also protect the connection part and the rotating shaft 4 of the left mounting bracket 1 and prevent the connection part and the rotating shaft 4 from being damaged during the collision, which would cause the entire pedal structure to collapse.

[0048] In some embodiments, the aforementioned support body has been optimized, specifically, as follows: Figure 1 As shown, the main body of the bracket also includes a back plate bracket 3, and the two sides of the back plate bracket 3 are connected to the bracket walls of the left mounting bracket 1 and the right mounting bracket 2, respectively.

[0049] In this embodiment, the backplate bracket 3 is located below the left mounting bracket 1 and the right mounting bracket 2, and is connected to the left mounting bracket 1 and the right mounting bracket 2 by a weld. This process is simple and can further enhance the connection strength between the left mounting bracket 1 and the right mounting bracket 2.

[0050] In some embodiments, the guide plate 11 and the left mounting bracket 1 are integrally die-cast. Compared with other connection methods such as welding, integral die-casting is not only simpler in process, but also ensures the connection strength between the guide plate 11 and the left mounting bracket 1, preventing the connection between the guide plate 11 and the left mounting bracket 1 from breaking in the event of a collision.

[0051] Furthermore, such as Figure 2 As shown, in this embodiment, the guide plate 11 is arranged perpendicular to the connecting part of the left mounting bracket 1, which can ensure that the guide plate 11 has a larger contact area when it collides with the steering column, and further reduce the impact on the steering column.

[0052] In some embodiments, the guide plate 11 described above has been optimized, specifically, as follows: Figure 2 As shown, the guide plate 11 includes an arc-shaped segment, a vertical segment, and a reinforcing segment, which are connected in sequence. The arc-shaped segment has an arc-shaped curved surface structure. The vertical segment is arranged parallel to the vertical steering column. The reinforcing segment is arranged at an angle to the vertical segment and extends along the direction away from the vertical steering column.

[0053] In fact, when the guide plate 11 collides with the steering column, the arc-shaped section of the guide plate 11 first contacts the steering column. Due to its curved surface structure, the arc-shaped section of the guide plate 11 changes the collision effect between the left mounting bracket 1 and the steering column, causing the movement direction of the left mounting bracket 1 to change from towards the steering column to along the tangent direction of the arc-shaped section of the guide plate 11. Next, the vertical section of the guide plate 11 contacts the steering column. Since the vertical section of the guide plate 11 is set parallel to the steering column, the left mounting bracket 1 can continue to move along the tangent direction of the arc-shaped section of the guide plate 11 without directly colliding with the steering column. When the left mounting bracket 1 moves to the point where the reinforcing section of the guide plate 11 approaches the steering column, the vertical section of the reinforcing section of the guide plate 11 is angled and extends in a direction away from the vertical steering column. Therefore, the left mounting bracket 1 can gradually move away from the steering column, ultimately solving the problem of direct collision between the left mounting bracket 1 and the steering column.

[0054] In some embodiments, the left mounting bracket 1 described above has been optimized, specifically, as follows: Figure 2 As shown, the base of the left mounting bracket 1 has multiple mounting holes;

[0055] Furthermore, the base of the right mounting bracket 2 also has multiple mounting holes.

[0056] In this embodiment, two mounting holes are respectively opened on the base of the left mounting bracket 1 and the right mounting bracket 2. The mounting holes are used to bolt the bracket body to the front panel of the vehicle, which can not only strengthen the connection between the bracket body and the front panel of the vehicle, but also facilitate technicians to disassemble the brake pedal, which is beneficial to the maintenance and repair of the car.

[0057] In some embodiments, the aforementioned pedal wall 5 has been optimized, specifically, as follows: Figure 1 As shown, the pedal wall 5 is a solid structure, and the pedal is connected to the end of the pedal wall 5.

[0058] In actual operation, the pedal wall 5 is a solid structure, which on the one hand enhances the overall structural strength of the brake pedal; on the other hand, it can also prevent the pedal wall 5 from breaking due to excessive impact in the event of a collision, thereby preventing injury to the driver's leg.

[0059] A vehicle, specifically, the vehicle includes any of the above-described brake pedal structures for optimized collision safety.
