Description

Technical Field

[0001] This utility model belongs to the field of automotive pedal technology, specifically relating to an automotive pedal structure. Background Technology

[0002] The accelerator pedal controls the amount of fuel supplied to the engine to accelerate the vehicle; the brake pedal is used to decelerate or stop the vehicle, bringing it to a safe stop via the braking system; and the clutch pedal is used to disconnect the power connection between the engine and the transmission to facilitate gear shifting. These pedals are essential for driving operations.

[0003] For novice drivers, the perception of accelerator pedal pressure is weak, making it difficult to maintain stable control. This results in frequent and significant changes in pedal pressure during driving, leading to frequent acceleration and deceleration, which negatively impacts the passenger experience and can cause motion sickness. Therefore, a new type of automotive pedal structure is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a car pedal structure.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A car pedal structure includes a mounting plate fixedly connected to a car chassis. A mounting cylinder is fixedly connected to the bottom of the mounting plate. A rotating shaft is coaxially mounted on the mounting cylinder. An encoder is embedded in the downward protrusion of the mounting plate, and the encoder is coaxially inserted into the prism end of the rotating shaft. A pedal is fixedly sleeved on the rotating shaft, the pedal passing through the mounting plate. The mounting plate has a through groove adapted to the rotation of the pedal. A first spring is installed in the inner cavity of the mounting cylinder. The inner end of the first spring is fixedly connected to the rotating shaft, and the outer end of the first spring is fixedly connected to the mounting cylinder. A plurality of second springs are also installed in the inner cavity of the mounting cylinder, and the plurality of second springs are evenly distributed with the axis of the rotating shaft as the center. The outer end of each second spring is fixedly connected to the mounting cylinder, and the inner end of each second spring is a free end. A stop bar extends from the outer wall of the rotating shaft parallel to its own axis, and the stop bar rotates towards the free end of the second spring when the pedal is pressed.

[0007] As a preferred embodiment of this utility model, the mounting cylinder is coaxially and fixedly embedded with a bearing, and the inner ring of the bearing is coaxially and fixedly connected to the rotating shaft.

[0008] As a preferred technical solution of this utility model, when the pedal is pressed, the inner end of the first spring winds towards the shaft.

[0009] As a preferred technical solution of this utility model, after the stop bar rotates and contacts the free end of the second mainspring, the free end of the second mainspring winds around the shaft.

[0010] As a preferred technical solution of this utility model, the inner wall of the mounting cylinder extends with a positioning component for positioning the initial position of the rotating shaft, and the positioning rotating shaft is provided with a rounded positioning groove that is adapted to the positioning component.

[0011] As a preferred embodiment of the present invention, the positioning component includes a socket extending from the inner wall of the mounting cylinder, the socket being slidably connected to a movable frame pointing towards the axis of rotation, the end of the movable frame being rotatably connected to a roller adapted to a rounded corner positioning groove, and the end of the movable frame being connected to a spring that pushes the roller toward the axis of rotation.

[0012] As a preferred embodiment of this utility model, the pedal is fitted with a dustproof sleeve that seals the top of the through groove of the mounting plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this application, when the driver presses the pedal, the pivot shaft touches the free end of the second spring every time it rotates through a fixed angle, causing the pedal rebound force to suddenly increase and be felt by the driver's leg. This allows the driver to sense the pedal's position with their foot and also helps the driver maintain the pedal position (keeping the pedal rotation angle at the point of sudden rebound force change). This makes it easier for novice drivers to control the accelerator pedal stably, thereby controlling the vehicle speed steadily, reducing frequent changes in vehicle speed, and improving the riding experience.

[0015] Second, in this application, the greater the pedal depth, the more second springs that block the rotation of the pivot shaft, which increases the difference in the return force of different pedal depths. This makes it easier for the driver to sense the pedal depth with their foot, reduces the probability of the accelerator pedal being pressed too deeply in error, and improves driving safety.

[0016] Third, this application also includes a positioning component, which makes it easy for the accelerator pedal to remain in its initial position when it is not pressed, and the accelerator pedal needs to be rotated by applying more than a certain force, thus reducing accidental activation of the accelerator pedal.

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] Please see Figure 1-6 A car pedal structure includes a mounting plate 1 fixedly connected to the car chassis. A mounting cylinder 2 is fixedly connected to the bottom of the mounting plate 1, and a rotating shaft 3 is coaxially mounted on the mounting cylinder 2. A bearing 6 is coaxially fixedly embedded in the mounting cylinder 2, and the inner ring of the bearing 6 is coaxially fixedly connected to the rotating shaft 3. An encoder 4 is embedded in the downward protrusion of the mounting plate 1, and the prism end of the rotating shaft 3 is coaxially inserted into the encoder 4. The encoder 4 is used to detect the rotation angle of the pedal 5 and transmit it to the vehicle's computer for vehicle control. The rotating shaft 3 is fixedly fitted with the pedal 5. The pedal 5 passes through the mounting plate 1, and the mounting plate 1 has a through groove adapted to the rotation of the pedal 5. A dust cover 10, made of a flexible material such as leather, is fitted onto the pedal 5, sealing the top of the through groove in the mounting plate 1. The dust cover 10 does not affect the rotation of the pedal 5.

[0031] A first mainspring 7 is installed inside the mounting cylinder 2. The inner end of the first mainspring 7 is fixedly connected to the rotating shaft 3, and the outer end of the first mainspring 7 is fixedly connected to the mounting cylinder 2. Several second mainsprings 8 are also installed inside the mounting cylinder 2, and these second mainsprings 8 are evenly distributed with rotation around the axis of the rotating shaft 3. In the embodiment shown in the attached drawing, three second mainsprings 8 are provided. The outer end of each second mainspring 8 is fixedly connected to the mounting cylinder 2, and the inner end of each second mainspring 8 is a free end. A stop bar 301 extends from the outer wall of the rotating shaft 3, parallel to its own axis, and when the pedal 5 is pressed, the stop bar 301 rotates towards the free end of the second mainspring 8.

[0032] When pedal 5 is pressed, the inner end of the first spring 7 winds towards the shaft 3, thereby generating the stored force for the pedal 5 to rebound.

[0033] After the stop bar 301 rotates and contacts the free end of the second mainspring 8, the free end of the second mainspring 8 winds around the rotating shaft 3. As the pedal 5 is pressed and rotated, the rotating shaft 3 contacts a free end of the second mainspring 8 every time it rotates through a fixed angle, causing the rebound force of the pedal 5 to suddenly increase and be felt by the driver's leg.

[0034] The inner wall of the mounting cylinder 2 extends a positioning component 9 for positioning the initial position of the rotating shaft 3, and the positioning rotating shaft 3 is provided with a rounded positioning groove 302 that is adapted to the positioning component 9.

[0035] The positioning assembly 9 includes a socket 904 extending from the inner wall of the mounting cylinder 2. A movable frame 901, pointing towards the axis of the rotating shaft 3, is slidably connected to the socket 904. A roller 902, adapted to a rounded positioning groove 302, is rotatably connected to the end of the movable frame 901. A spring 903 is connected to the end of the movable frame 901 to push the roller 902 towards the rotating shaft 3. When the pedal 5 is in its initial position, the spring 903 pushes the roller 902 into the rounded positioning groove 302 of the positioning rotating shaft 3, preventing the pedal 5 from rotating due to vibration or other minor forces.

[0036] Working principle:

[0037] When driving the vehicle, the spring 903 of the positioning component 9 pushes the roller 902 into the rounded positioning groove 302 of the positioning shaft 3. When the pedal 5 is pressed, a certain amount of force is required for the roller 902 to roll out of the rounded positioning groove 302. As the shaft 3 rotates, the roller 902 always rolls along the outer wall of the shaft 3. When the pedal 5 rotates, the inner end of the first spring 7 winds towards the shaft 3, generating the stored force for the pedal 5 to rebound. At the same time, the shaft 3 touches the free end of a second spring 8 every time it rotates through a fixed angle, so that the rebound force of the pedal 5 suddenly increases and is felt by the driver's leg. This allows the driver's foot to sense the pedal 5's pressing position and also helps the driver maintain the pressing position (the pedal 5's rotation angle is kept at the point of sudden change in rebound force). At the same time, the greater the pedal 5 is pressed, the more second springs 8 are blocked from rotating the shaft 3, which increases the difference in the return force of different pedal 5 pressing depths, making it easier for the driver's foot to sense the pressing depth of the pedal 5.

[0038] When the pedal 5 stops being pressed, under the elastic force of the first spring 7 and several second springs 8, the pedal 5 rotates back to its initial position, and under the pressure of the spring 903, the roller 902 is locked into the rounded positioning groove 302 of the positioning shaft 3.

[0039] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
