Description

Technical Field

[0001] The present application relates to the field of automobile brakes, and in particular to a brake pedal. Background Art

[0002] The brake pedal is an important component in a car, used to control the deceleration and parking of the car. When the driver is driving the car, the amplitude of stepping on the brake pedal will directly affect the braking effect of the car. There is often a problem with the traditional brake pedal design, that is, when the driver steps on the brake pedal, he may unconsciously step on the brake pedal too much, causing the car to decelerate sharply from a high-speed driving state or even stop directly, which will cause the occupants of the car to lean forward due to inertia, causing safety hazards. Therefore, how to design a device that can provide buffering when the driver steps on the brake pedal to avoid excessive braking is a problem that needs to be solved in the current field of automotive parts technology. Utility Model Content

[0003] In order to reduce the probability of the driver unconsciously over-stepping on the brake pedal and reduce the damage to the occupants of the vehicle caused by emergency stops, the present application provides a brake pedal.

[0004] The present application provides a brake pedal adopting the following technical solution:

[0005] A brake pedal comprises a mounting plate, a pedal rotatably connected to the mounting plate at one end, and a support and buffer assembly connected between the mounting plate and the pedal, the support and buffer assembly comprising a support tube installed between the mounting plate and the pedal, a buffer spring installed between the mounting plate and the pedal, and a pressure spring installed between the mounting plate and the pedal, when the pedal rotates, the pedal squeezes the buffer spring; when the pedal continues to rotate after rotating a set angle, the pedal squeezes the buffer spring and the pressure spring at the same time.

[0006] By adopting the above technical solution, when the driver steps on the pedal, the buffer spring mainly provides a gentle resistance force in the initial stage, so that the driver can easily control the pedal. When the pedal is stepped on to a certain angle, the pressure spring starts to work, increasing the difficulty of stepping on it to prevent unconscious over-stepping on the pedal, reducing the probability of the driver unconsciously stepping on the brake pedal and causing an emergency stop, and reducing the damage to the occupants of the vehicle caused by the emergency stop.

[0007] Optionally, a mounting groove is provided on the mounting plate for the buffer spring to be embedded in, and the support tube is open at one end. The open end of the support tube is slidably connected in the mounting groove, and the closed end of the support tube away from the mounting plate is abutted against the pedal, and the pressure spring and the buffer spring are both installed in the mounting groove and the support tube.

[0008] By adopting the above technical solution, the buffer spring and the pressure spring can be protected.

[0009] Optionally, one end of the buffer spring abuts against the bottom of the installation groove, and the other end of the buffer spring abuts against the closed end of the support tube; one end of the pressure spring abuts against the bottom of the installation groove, and a gap is left between the other end and the closed end of the support tube.

[0010] By adopting the above technical solution, when the pedal starts to rotate, only the buffer spring provides resistance for the pedal, and at the same time the support tube also slides in the installation groove. When the pedal rotates and drives the support tube to slide until the closed end of the support tube abuts against the pressure spring, the pressure spring and the buffer spring will jointly provide resistance for the pedal.

[0011] Optionally, a clamping wheel is rotatably connected to the pedal, and the clamping wheel abuts against the support tube.

[0012] By adopting the above technical solution, it is ensured that when the pedal makes a circular rotation, it can smoothly drive the support tube to slide vertically without getting stuck.

[0013] Optionally, the mounting plate includes a plate body and a support body installed on one side of the plate body, and the mounting groove includes through holes penetrating opposite sides of the plate body and a placement groove opened on a side of the support body facing the plate body.

[0014] By adopting the above technical solution, the height of the opened installation groove is sufficient, and the depth requirement of the placement groove can be met without increasing the thickness of the installation plate too much.

[0015] Optionally, the support body is fixedly connected to the plate body.

[0016] By adopting the above technical solution, the overall structure is made more stable.

[0017] Optionally, the support body is threadedly connected to the plate body.

[0018] By adopting the above technical solution, it is easy to adjust the depth of the installation groove and to replace the buffer spring and the pressure spring, and the operation is more convenient and flexible.

[0019] Optionally, a protective tube is fixedly connected between the mounting plate and the supporting tube, the protective tube is a corrugated tube, and the protective tube is made of rubber material.

[0020] By adopting the above technical solution, it is possible to reduce the damage to the buffer spring and the pressure spring caused by foreign impurities entering between the support tube and the installation groove.

[0021] Optionally, a sealing groove for the protective tube to be embedded in is opened on the outer wall of the support tube, and one end of the protective tube is fixedly connected to the mounting plate, and the other end is embedded in the sealing groove.

[0022] By adopting the above technical solution, the seal between the protection tube and the support tube is made tighter.

[0023] Optionally, the elastic coefficient of the buffer spring is smaller than the elastic coefficient of the pressure spring.

[0024] By adopting the above technical solution, when the driver starts to control the pedal rotation to slow down, only a small force is needed to slow down the wheels; and if an emergency situation occurs and emergency braking is required, the driver needs to apply a greater force to the pedal.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. This application uses a support buffer component to buffer the force when the driver steps on the pedal, effectively reducing the sharp deceleration of the car caused by excessive stepping, ensuring the safety of the occupants and improving the comfort of the ride;

[0027] 2. This application further enhances the buffering effect by adopting a design that combines an auxiliary spring with a buffer spring. At the same time, by adjusting the position of the support body, the buffering force can be fine-tuned to meet the needs of different driving habits. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses a brake pedal. Figure 1 The brake pedal includes a mounting plate 1, a pedal 2 rotatably connected to the mounting plate 1 at one end, and a supporting buffer assembly 3 installed between the mounting plate 1 and the pedal 2 for fixing the relative positions of the pedal 2 and the mounting plate 1.

[0035] Reference Figure 1 and Figure 2 The support buffer assembly 3 includes a support cylinder 31 installed between the mounting plate 1 and the pedal 2, a buffer spring 32 installed in the support cylinder 31, and a pressure spring 33 installed in the support cylinder 31. When the pedal 2 rotates, the buffer spring 32 is first compressed; and when the pedal 2 rotates to a certain set angle, the buffer spring 32 and the pressure spring 33 are compressed at the same time.

[0036] The elastic coefficient of the buffer spring 32 is smaller than the elastic coefficient of the pressure spring 33 , so that the pressure spring 33 provides resistance for the driver to further step on the pedal 2 .

[0037] When the driver steps on the pedal 2, the buffer spring 32 provides a gentle resistance force in the initial stage, so that the driver can easily control the pedal 2. When the pedal 2 is stepped on to a certain angle, the pressure spring 33 starts to work, increasing the difficulty of stepping on it, which serves as feedback to the driver to prevent unconscious excessive stepping on it, and reduces the situation where the driver steps on the pedal 2 excessively when braking unconsciously and causes an emergency stop. When encountering an emergency, the driver consciously steps on the pedal 2 with force, so that the pedal 2 can overcome the elastic force of the buffer spring 32 and the pressure spring 33 at the same time, so that the car can brake quickly and achieve braking. While reducing the possibility that the driver's unconscious braking causes the occupants of the car to lean forward due to inertia, it can also ensure that rapid braking can be achieved in an emergency.

[0038] Reference Figure 2 A mounting groove 13 is provided on the mounting plate 1, and a support tube 31 is open at one end, and its open end is slidably connected in the mounting groove 13. The closed end of the support tube 31 abuts against the pedal 2. The buffer spring 32 and the pressure spring 33 are both installed in the mounting groove 13 and the support tube 31, and the axes of the buffer spring 32 and the pressure spring 33 coincide.

[0039] Specifically, one end of the buffer spring 32 abuts against the bottom of the mounting groove 13, and the other end abuts against the closed end of the support tube 31; one end of the pressure spring 33 also abuts against the bottom of the mounting groove 13, but a certain gap is deliberately left between the other end and the closed end of the support tube 31. When the driver steps on the pedal 2, the pedal 2 will accumulate pressure on the buffer spring 32; when the pedal 2 rotates to a set angle so that one end of the pressure spring 33 away from the bottom of the mounting groove 13 abuts against the closed end of the support tube 31, force is applied to the pedal 2, and the pressure spring 33 gradually starts to work, so that the driver needs to overcome the elastic force of the buffer spring 32 and the pressure spring 33 at the same time to drive the pedal 2 to rotate, achieving a progressive resistance effect.

[0040] Reference Figure 3 A clamping wheel 21 is rotatably connected to the side of the pedal 2 facing the mounting plate 1, and the clamping wheel 21 is tightly abutted against the outer surface of the closed end of the support tube 31. When the pedal 2 rotates around the hinge axis with the mounting plate 1, the clamping wheel 21 also rotates on the closed end of the support tube 31 to meet the needs of the pedal 2 rotating.

[0041] Reference Figure 2 The mounting plate 1 includes a plate body 11 of the main body and a support body 12 installed on one side of the plate body 11. At the same time, the mounting groove 13 includes a through hole 131 penetrating through the opposite sides of the plate body 11 and a placement groove 132 opened on the side of the support body 12 facing the plate body 11.

[0042] In an example of the present application, the support body 12 is integrally fixed to the plate body 11 to form an integral structure, so that the overall strength and stability are better.

[0043] Reference Figure 4 In another example of the present application, the support body 12 and the plate body 11 are detachably connected through a threaded connection. Specifically, an external thread is processed on the outer wall of the support body 12, and an internal thread threadedly connected to the support body 12 is processed in the through hole 131 of the plate body 11. By screwing the support body 12 on the plate body 11, the detachable connection between the support body 12 and the plate body 11 can be completed.

[0044] At the same time, in order to facilitate the position of the support body 12 on the plate body 11, a handle 14 is fixedly connected to the side of the support body 12 away from the plate body 11. By rotating the handle 14, the relative position between the support body 12 and the plate body 11 can be conveniently adjusted, thereby changing the depth of the installation groove 13. This design can adapt to the pedaling habits and braking needs of different drivers, improving its personalization and applicability. At the same time, when the support spring and the pressure spring are fatigued and deformed after being used for a period of time, the compression amount of the support spring and the pressure spring can also be adjusted, or the support spring and the compression spring can be replaced.

[0045] Reference Figure 2and Figure 4 In order to prevent foreign matter from entering the mounting groove 13 from the open end of the support tube 31, thereby damaging the buffer spring 32 and the pressure spring 33 in the mounting groove 13, a protective tube 4 is installed between the mounting plate 1 and the support tube 31. The protective tube 4 is in the shape of a corrugated tube and is made of rubber material. While protecting the support tube 31 and the mounting plate 1, it also has a telescopic function to meet the sliding changes between the support tube 31 and the mounting groove 13.

[0046] Specifically, a sealing groove 311 for the protective tube 4 to be embedded is opened on the outer wall of the support tube 31, one end of the protective tube 4 is embedded in the sealing groove 311 and fixedly connected to the support tube 31; an auxiliary tube 15 is fixedly connected to the mounting plate 1, the auxiliary tube 15 is sleeved on the mounting groove 13, and the other end of the protective tube 4 is sleeved on the auxiliary tube 15 and fixedly connected to the mounting plate 1, thereby realizing the installation of the protective tube 4.

[0047] Reference Figure 1 In order to fix the initial state of the pedal 2, a limiting column 5 is fixed on the mounting plate 1, and the limiting column 5 is located on the side of the hinge axis of the pedal 2 and the mounting plate 1 away from the support buffer assembly 3. Under normal conditions, under the elastic force of the buffer spring 32, the side of the pedal 2 away from the buffer spring 32 abuts against the limiting column 5, thereby fixing the position of the pedal 2 and keeping the pedal 2 in a balanced state. The limiting column 5 can be a bolt, which is threadedly connected to the mounting plate 1 to facilitate adjusting the height of the limiting column 5.

[0048] The implementation principle of a brake pedal in an embodiment of the present application is as follows: Under normal conditions, the position of the pedal 2 relative to the mounting plate 1 is fixed by the elastic force of the buffer spring 32. When the driver steps on the pedal 2, a force will be applied to the pedal 2 to rotate around the mounting plate 1, and the pedal 2 will be driven to rotate. At this time, the pedal 2 will drive the support tube 31 to slide relative to the mounting plate 1 to squeeze the buffer spring 32 to achieve wheel deceleration. When the driver operates the pedal 2 to rotate a certain angle, the closed end of the support tube 31 will abut against the pressure spring 33, so that the pressure spring 33 provides resistance to the rotation of the pedal 2, reducing the sudden braking phenomenon caused by the driver's unconscious braking. The probability of the driver unconsciously stepping on the brake pedal 2 is greatly reduced, and the damage to the occupants of the vehicle caused by sudden stops is reduced.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
