[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] like Figures 1 to 7 As shown, this is a preferred embodiment of the accelerator pedal of the present invention, which includes a housing 1, a pedal arm 2, a sensor 3, and a spring 4. One end of the pedal arm 2 is installed on the outside of the housing 1, and the movable end of the pedal arm 2 extends into the housing 1 with a connecting rod 22. The sensor 3 is installed on the connecting rod 22, and the end of the connecting rod 22 is provided with a mounting seat 23 for installing the spring 4. The two ends of the spring 4 are respectively installed on the housing 1 and the mounting seat 23.

[0032] Specifically, after one end of the pedal arm 2 is installed in the housing 1, the end furthest from the installation position is the movable end. The connecting rod 22 is located on the bottom surface of the middle part of the pedal arm 2, and the mounting base 23 is movably fitted inside the housing 1. The lower end of the spring 4 is installed in the housing 1, and the upper end of the spring 4 is installed in the mounting base 23. An angle is formed between the upper and lower ends of the spring 4, so that the spring 4 is set in a bent shape, which can generate axial and radial components when it rebounds. In this embodiment, the sensor 3 for detecting position changes is installed on the mounting base 23 at the end of the connecting rod 22.

[0033] During operation, pedal arm 2 drives mounting base 23 to move downwards via connecting rod 22, and drives mounting base 23 to move upwards via spring 4. When pedal arm 2 is pressed down, the pressure is transmitted to mounting base 23 via connecting rod 22, causing mounting base 23 to move downwards and compress spring 4. The elastic force generated by the compression of spring 4 is transmitted to the pressure rod via mounting base 23. When pedal arm 2 is released, spring 4 drives mounting base 23 to move upwards, and pushes pedal arm 2 back up via connecting rod 22, thus returning it to its initial position. Sensor 3 moves upwards / downwards synchronously with connecting rod 22 to detect changes in the position of connecting rod 22.

[0034] The key feature of this invention is that the accelerator pedal is connected to the pedal arm 2 and the spring 4 via the mounting base 23. The sensor 3 installed on the connecting rod 22 detects the movement changes of the pedal arm 2 to realize the accelerator pedal function. The rebound force of the pedal arm 2 is directly provided by the spring 4. Compared with the traditional accelerator pedal, the structure is simpler, the number of parts is less, the assembly steps and product weight can be reduced, and the production cost can be lowered.

[0035] In this embodiment, the surface of the housing 1 is provided with an opening 12, and the connecting rod 22 extends into the housing 1 after passing through the opening 12; the top of the mounting base 23 is in active contact with the inner wall of the housing 1 around the opening 12 to prevent the connecting rod 22 from detaching from the housing 1.

[0036] In this embodiment, the mounting base 23 is a laterally extending plate, and an arc-shaped friction wall 11 is formed on the inner wall of the housing 1. A friction block 6 is also provided between the mounting base 23 and the friction wall 11, and the friction block 6 is driven by the mounting base 23. The friction block 6 and the mounting base 23 move synchronously. During the movement, the friction block 6 contacts and rubs against the friction wall 11, generating frictional force.

[0037] In this embodiment, a wedge 5 is provided between the mounting base 23 and the spring 4. The wedge 5 is slidably mounted on the mounting base 23 and abuts against the friction block 6.

[0038] The upper end of the spring 4 is mounted on the lower end face of the wedge block 5. When the pedal arm 2 is pressed down, the mounting base 23 drives the wedge block 5 to squeeze the spring 4. The elastic force generated by the compression of the spring 4 is transmitted to the wedge block 5. The axial direction of the spring 4 causes the wedge block 5 to abut against the lower end face of the mounting base 23. The radial component of the spring 4 pushes the wedge block 5 towards the friction wall 11. The wedge block 5 presses the friction block 6 towards the friction wall 11, so that the friction block 6 and the friction wall 11 come into contact and rub against each other.

[0039] In this embodiment, the friction block 6 includes a plug-in portion 61, and the mounting base 23 is provided with a slot 231 corresponding to the plug-in portion 61. The plug-in portion 61 is embedded in the slot 231. The slot 231 is a rectangular groove, and the groove direction of the slot 231 faces the friction wall 11. The plug-in portion 61 is plate-shaped. The plug-in portion 61 is embedded in the slot 231 to install the friction block 6 onto the mounting base 23, resulting in a stable structure.

[0040] In this embodiment, the friction block 6 has a friction portion 62 that fits against the friction wall 11 on the side near the friction wall 11, and an abutment portion 63 that fits against the surface of the wedge block 5 on the side near the wedge block 5. The curvature of the friction portion 62 matches the curvature of the friction wall 11, resulting in a good fit. The end of the wedge block 5 is curved, and the abutment portion 63 is a curved groove 233, which increases the contact area between the wedge block 5 and the abutment portion 63, reduces wear, and improves transmission efficiency.

[0041] In other embodiments, the friction block 6 may also be formed as a single part with the wedge block 5. The integral molding of the friction block 6 and the wedge block 5 further reduces the number of parts and assembly steps.

[0042] In this embodiment, a groove 232 is provided on the lower end face of the mounting base 23 along its length direction, and a slider 51 corresponding to the groove 232 is provided on the upper end face of the wedge block 5. The slider 51 is movably fitted within the groove 232. By limiting the mutual positioning of the slider 51 and the groove 232, the wedge block 5 is restricted to sliding back and forth relative to the transmission part only in the direction of approaching / moving away from the friction wall 11, resulting in a more stable structure.

[0043] In other embodiments, a slider 51 may be provided on the mounting base 23, and a corresponding groove 232 may be provided on the wedge block 5.

[0044] In this embodiment, the surface of the wedge block 5 is recessed to form a receiving groove 52, and a protrusion 53 is provided in the middle of the receiving groove 52. One end of the spring 4 is embedded in the receiving groove 52 and sleeved on the protrusion 53. A stop block 54 is also provided on the periphery of the receiving groove 52, and the stop block 54 is disposed between the spring 4 and the friction block 6. This prevents the spring 4 from detaching from the wedge block 5, strengthens the connection between the spring 4 and the wedge block 5, and also allows the radial component of the force of the spring 4 to be transmitted to the friction block 6 more efficiently through the wedge block 5.

[0045] A spring base 13 is provided inside the housing 1, and the other end of the spring 4 is installed in the spring base 13. In this embodiment, the spring base 13 is a groove with baffles on its periphery. During assembly, the lower end of the spring 4 is placed in the spring base 13, which eliminates the need for additional installation steps and improves assembly efficiency.

[0046] In this embodiment, one end of the pedal arm 2 is provided with a mounting part 21. The mounting part 21 includes an I-shaped plate 211, a connecting plate 212 with a certain flexibility, and a wedge-shaped guide block 213. The I-shaped plate 211 is connected to the pedal arm 2 through the connecting plate 212, and the guide block 213 is provided at the bottom of the I-shaped plate 211. The housing 1 is provided with a mounting groove 14 corresponding to the mounting part 21. The bottom of the mounting groove 14 is provided with a slot 15. The I-shaped plate 211 is installed in the mounting groove 14, and the guide block 213 and the slot 15 limit each other.

[0047] During assembly, the I-shaped plate 211 slides into the mounting groove 14, and is mutually limited by the groove wall of the mounting groove 14 and the inner wall of the I-shaped plate 211. When the I-shaped plate 211 moves to the preset installation position, the guide block 213 slides into the slot 15 to complete the installation. There is no need to check whether the installation is in place, and at the same time, the mounting part 21 is prevented from falling out of the mounting groove 14.

[0048] In this embodiment, the connecting plate 212 is made of soft plastic. When the pedal arm 2 is pressed down, the connecting plate 212 can produce different deformations according to different applied forces, so that the pedal arm 2 can rotate around the I-shaped plate 211 at a certain angle.

[0049] like Figures 8 to 10 As shown, another embodiment of this utility model is illustrated, wherein the mounting base 23 is a cylindrical assembly with a circular groove 233 at its bottom, and the upper end of the spring 4 is embedded in the groove 233. The groove 233 limits the spring 4, preventing it from detaching, further simplifying the structure and reducing the number of parts and assembly steps.

[0050] This specification uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
