Description

Technical Field

[0001] This invention relates to the field of integrated parking and braking technology for leisure and sightseeing vehicles, and particularly to a brake pedal structure with parking function. Background Technology

[0002] Currently, most leisure and sightseeing vehicles on the market have separate brakes and handbrakes. This method involves a large number of parts, high costs, and takes up a lot of space.

[0003] For example, a prior patent application (CN200480038775.2) discloses a brake pedal device for implementing service braking and lock-up braking. This device includes first and second brake pedal elements that move together with pressure applied for braking purposes. Service braking can be implemented by applying pressure to at least the first brake pedal element. The device also includes a locking device that can be easily activated by moving a second brake pedal element through a predetermined stroke to hold the second brake pedal element in a locked position for lock-up braking, and an unlocking device that is activated by applying pressure to the first brake pedal element to unlock the locking device and release the second brake pedal element. Although this device combines the brake pedal and handbrake, it still occupies a large amount of operating space in the driver's cab. Summary of the Invention

[0004] The purpose of this invention is to provide a brake pedal structure with parking function, so as to solve the problem that the brake pedal structure with parking function in the related technology occupies a large amount of operating space in the driver's cab.

[0005] This invention provides a brake pedal structure with a parking function. The brake pedal structure includes a mounting bracket and a pedal, comprising a brake pedal and a parking pedal. The brake pedal is hinged to the mounting bracket, and the parking pedal is hinged to the brake pedal. The brake pedal structure also includes a locking device, comprising a parking plate and a parking hook. The parking plate is disposed on the mounting bracket, and the parking hook is rotatably connected to the brake pedal. The parking hook has a first position separated from the parking plate and a second position engaged with the parking plate. The parking pedal is drively connected to the parking hook, and the parking pedal can rotate relative to the brake pedal to switch the parking hook between the first position and the second position.

[0006] As a preferred technical solution for a brake pedal structure with parking function, the brake pedal structure with parking function further includes a parking pedal return spring, which can drive the parking pedal to rotate relative to the brake pedal so as to drive the parking hook to move to the first position.

[0007] As a preferred technical solution for a brake pedal structure with parking function, the brake pedal can rotate relative to the mounting bracket to have a braking position and a non-braking position. The brake pedal also includes a brake pedal return spring, which can drive the brake pedal to move to the non-braking position.

[0008] As a preferred technical solution for a brake pedal structure with parking function, the locking device further includes a parking lever, the two ends of which can rotate relative to the parking pedal and the parking hook, respectively.

[0009] As a preferred technical solution for a brake pedal structure with parking function, the locking device further includes a parking lever bracket disposed on the parking pedal, and the parking lever bracket is rotatably connected to the parking lever.

[0010] As a preferred technical solution for a brake pedal structure with parking function, the brake pedal structure with parking function further includes a parking pedal surface pivot. The parking pedal includes a parking pedal surface and a bracket disposed on the parking pedal surface. The parking pedal surface pivot is rotatably connected to the parking pedal surface and the brake pedal respectively.

[0011] As a preferred technical solution for a brake pedal structure with parking function, the brake pedal includes a brake pedal surface and a brake pedal arm disposed on the brake pedal surface. The brake pedal arm and the mounting bracket are rotatably connected, the bracket is rotatably connected to the brake pedal arm, and the parking hook is rotatably connected to the brake pedal arm.

[0012] As a preferred technical solution for the brake pedal structure with parking function, one end of each of the two brackets is fixedly connected to the parking pedal surface, and the other end is rotatably connected to the parking pedal surface pivot. The two brake pedal arms are spaced apart and rotatably connected to the parking pedal surface pivot.

[0013] As a preferred technical solution for a brake pedal structure with parking function, when the parking hook is in the first position, the brake pedal surface and the parking pedal surface are flush.

[0014] As a preferred technical solution for a brake pedal structure with parking function, the brake pedal further includes a brake pedal shaft, a brake pedal shaft outer tube, and a push plate. The brake pedal shaft is fixedly connected to the mounting bracket. The brake pedal shaft outer tube is rotatably sleeved on the brake pedal shaft. The two brake pedal arms are spaced apart and fixedly connected to the brake pedal shaft outer tube. One end of the push plate is fixedly connected to the brake pedal shaft outer tube, and the other end is connected to the brake system.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention provides a brake pedal structure with a parking function. The structure includes a mounting bracket and a pedal, comprising a brake pedal and a parking pedal. The brake pedal is hinged to the mounting bracket, and the parking pedal is hinged to the brake pedal. The structure also includes a locking device comprising a parking plate and a parking hook. The parking plate is mounted on the mounting bracket, and the parking hook is rotatably connected to the brake pedal. The parking hook has a first position separated from the parking plate and a second position engaged with the parking plate. The parking pedal is drive-connected to the parking hook, and the parking pedal can rotate relative to the brake pedal to switch the parking hook between the first and second positions. Since the parking pedal is hinged to the brake pedal, pressing the brake pedal causes it to move the parking pedal. After the brake pedal applies pressure, the parking pedal is activated when the brake pedal's angle of movement exceeds a predetermined angle. The parking pedal then connects to the parking hook. Applying pressure to the parking pedal changes the parking hook from the first position (separated from the parking plate) to the second position (engaged with the parking plate), thus achieving the parking function. When you need to release the parking brake, press down firmly on the brake pedal with the ball of your foot (without pressing your toes). This will release the positive pressure between the parking hook and the parking plate. Continuing to apply force will create a gap, causing the parking hook and parking plate to separate. Then release your foot, and the brake pedal will return to its first position, releasing the parking brake. Because the parking pedal is hinged to the brake pedal, the two pedals are integrated, reducing the space occupied in the cab. Attached Figure Description

[0034] Embodiments of the present invention 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 are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1-8As shown, this embodiment provides a brake pedal structure with parking function. The brake pedal structure with parking function includes a mounting bracket 3 and a pedal 1. The pedal 1 includes a brake pedal 12 and a parking pedal 11. The brake pedal 12 is hinged to the mounting bracket 3, and the parking pedal 11 is hinged to the brake pedal 12. The brake pedal structure with parking function also includes a locking device 2. The locking device 2 includes a parking plate 23 and a parking hook 24. The parking plate 23 is disposed on the mounting bracket 3, and the parking hook 24 is rotatably connected to the brake pedal 12. The parking hook 24 has a first position 25 that is separated from the parking plate 23 and a second position 26 that is engaged with the parking plate 23. The parking pedal 11 is drively connected to the parking hook 24, and the parking pedal 11 can rotate relative to the brake pedal 12 to drive the parking hook 24 to switch between the first position 25 and the second position 26. In this embodiment, since the parking pedal 11 is hinged to the brake pedal 12, pressing the brake pedal 12 causes the brake pedal 12 to move together with the parking pedal 11. After the brake pedal 12 enters the braking state, the parking pedal 11 is activated when the movement angle of the brake pedal 12 is greater than a predetermined angle. The parking pedal 11 connects to the parking hook 24. By applying pressure to the parking pedal 11, the parking hook 24 can be switched from the first position 25, which is separated from the parking plate 23, to the second position 26, which is engaged with the parking plate 23, thereby realizing the parking function. When it is necessary to release the parking state, the brake pedal 12 is pressed down firmly with the ball of the foot (without the toes pressing the parking pedal 11). The positive pressure generated between the contact surface of the parking hook 24 and the parking plate 23 is eliminated. Continuing to apply force will create a gap, at which point the parking hook 24 separates from the parking plate 23. Then, the ball of the foot is released, and the parking hook 24 returns to its original position. Figure 7 Position 25 in the middle, parking is released. Since the parking pedal 11 is hinged to the brake pedal 12, the two pedals are integrated, which reduces the space occupied in the cab.

[0036] Optionally, the parking pedal 11 also includes a parking pedal return spring 113, which can drive the parking pedal 11 to rotate relative to the brake pedal 12 to move the parking hook 24 to the first position 25. Figure 1 In this embodiment, the parking pedal return spring 113 is a torsion spring. One end of the torsion spring abuts against the brake pedal 12, and the other end abuts against the parking pedal 11. Since the parking pedal 11 is connected to the parking hook 24, under the action of the parking pedal return spring 113, after the locking device 2 is unlocked, the parking hook 24 can move from the second position 26 to the first position 25.

[0037] Optionally, the brake pedal 12 is rotatable relative to the mounting bracket 3 to have a braking position and a non-braking position. The brake pedal 12 also includes a pedal return spring 126, which can drive the brake pedal 12 to move to the non-braking position. Figure 2 As shown, the pedal return spring 126 is a torsion spring. One end of the torsion spring abuts against the brake pedal 12, and the other end abuts against the mounting bracket 3. The torsion spring can move the brake pedal 12 from the braking position to the non-braking position.

[0038] Optionally, the locking device 2 further includes a parking lever 22, the two ends of which are rotatable relative to the parking pedal 11 and the parking hook 24, respectively. Preferably, the locking device 2 further includes a parking lever bracket 21 disposed on the parking pedal 11, the parking lever bracket 21 being rotatably connected to the parking lever 22. In this embodiment, both the upper and lower ends of the parking lever 22 are bent at 90° to facilitate insertion into the pre-drilled through holes of the parking hook 24 and the parking lever bracket 21.

[0039] Optionally, the brake pedal structure with parking function further includes a parking pedal surface pivot 114. The parking pedal 11 includes a parking pedal surface 111 and a bracket 112 disposed on the parking pedal surface 111. The parking pedal surface pivot 114 is rotatably connected to both the parking pedal surface 111 and the brake pedal 12. In this embodiment, the parking pedal surface pivot 114 is rotatably connected to both the parking pedal surface 111 and the brake pedal 12. On the one hand, the parking pedal surface 111 can move with the brake pedal 12; on the other hand, the parking pedal surface 111 can move around the parking pedal surface pivot 114.

[0040] Optionally, the brake pedal includes a brake pedal surface 121 and a brake pedal arm 122 disposed on the brake pedal surface 121. The brake pedal arm 122 is rotatably connected to the mounting bracket 3. The bracket 112 is rotatably connected to the brake pedal arm 122, and the parking hook 24 is rotatably connected to the brake pedal arm 122. In this embodiment, the bracket 112 is rotatably connected to the brake pedal arm 122, and the parking hook 24 is rotatably connected to the brake pedal arm 122. The parking hook 24 is divided into two parts, a hook body 242 and a hook handle 241, at the connection between the brake pedal arm 122 and the parking hook 24. The hook handle 241 of the parking hook 24 is rotatably connected to the parking pedal surface 111, and the hook body 242 is used to cooperate with the parking hanger 23.

[0041] Optionally, one end of each of the two brackets 112 is fixedly connected to the parking pedal surface 111, and the other end is rotatably connected to the parking pedal surface pivot 114. Two brake pedal arms 122 are spaced apart and rotatably connected to the parking pedal surface pivot 114. In this embodiment, two brackets 112 and two brake pedal arms 122 are used and spaced apart. Compared to using only one bracket 112 or brake pedal arm 122, this arrangement results in more even stress distribution on the parking pedal surface pivot 114, preventing deformation and improving its durability. In other embodiments, a connecting plate is provided between the two brake pedal arms 122. The strength of the brake pedal arms 122 can be increased by providing the connecting plate.

[0042] Optionally, when the parking hook 24 is in the first position 25, the brake pedal surface 121 and the parking pedal surface 111 are flush. In this embodiment, the surfaces of the brake pedal surface 121 and the parking pedal surface 111 that are in contact serve as limiting surfaces. When the parking pedal 11 moves from the second position 26 to the first position 25 under the action of the parking pedal return spring 113, the limiting surfaces play a limiting role, making the brake pedal surface 121 and the parking pedal surface 111 flush.

[0043] Optionally, the brake pedal 12 further includes a brake pedal shaft 123, a brake pedal shaft outer tube 124, and a push plate 125. The brake pedal shaft 123 is fixedly connected to the mounting bracket 3. The brake pedal shaft outer tube 124 is rotatably sleeved on the brake pedal shaft 123. Two brake pedal arms 122 are spaced apart and fixedly connected to the brake pedal shaft outer tube 124. One end of the push plate 125 is fixedly connected to the brake pedal shaft outer tube 124, and the other end is connected to the brake system. A pedal return spring 126 is sleeved on the brake pedal shaft outer tube 124. One end of the pedal return spring 126 is fixedly connected to the mounting bracket 3, and the other end is fixedly connected to the push plate 125, so that the brake pedal 12 can automatically return to its original position. In this embodiment, the brake pedal arms 122 and the push plate 125 are fixedly connected to the brake pedal shaft outer tube 124. When the brake pedal 12 moves from the non-braking position to the braking position, the push plate 125 also rotates through the corresponding angle, causing the brake system to start working. When the force applied to the brake pedal 12 is removed, the brake pedal 12 returns to the non-braking position due to the pedal return spring 126 driving it.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
