[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings:

[0031] Example 1 provides a protective device for a car pedal 1, such as Figures 1-7 As shown, a pressure sensor 55 is provided on at least one side wall of the side pedal 5 of the car pedal 1, and a protective plate 56 is provided at the front end / detection end of the pressure sensor 55.

[0032] The pressure sensor 55 on the side pedal 5 detects the collision with obstacles during the movement of the side pedal 5. Based on the detection signal of the pressure sensor 55, the side pedal 5 is controlled to stop extending or retracting or to take corresponding obstacle avoidance measures to protect the car pedal 1, reduce damage, and improve the user experience. The protective plate 56 receives the collision force and protects the pressure sensor 55.

[0033] See Figure 1 and Figure 2 From the perspective of the side pedal 5, pressure sensors 55 are respectively set on the front and right sides to detect the obstacle collision when the side pedal 5 is deployed / extended; pressure sensors 55 are set on the rear and left sides to detect the obstacle collision when the side pedal 5 is retracted; the front side of the side pedal 5 is provided with a chamfer. Figure 6 Part of the protective plate 56 was removed, and a pressure sensor 55 was also installed on the chamfer.

[0034] The side pedal 5 includes a base plate 51. Figure 6 A protective plate 58 is also shown on the upper side of the base plate 51; the outer wall of the protective plate 58 is located longitudinally between the inner wall and the outer wall of the corresponding protective plate 56, which reduces the force on the protective plate 56 during the stepping of the side pedal 5 and improves its durability.

[0035] Example 2, as Figure 5 The side step 5 also includes a plastic part 52 disposed on the outer side of the base plate 51 and the protective plate 56 to improve aesthetics. The side of the plastic part 52 is a flexible part, which does not affect the impact force of the protective plate 56. The upper side of the plastic part 52 is provided with anti-slip texture 53. The plastic part 52 can be made of plastic or rubber, etc.

[0036] Example 3 illustrates a specific automotive pedal 1, which also includes an active seat 2, a driven seat 3, and a connecting rod 4; one end of one connecting rod 4 is mounted on the drive shaft 24 of the drive motor 23 of the active seat 2, and the other end is hinged to one side of the side pedal 5; one end of another connecting rod 4 is hinged to the driven seat 3, and the other end is hinged to the other side of the side pedal 5; forming a quadrilateral or near-quadrilateral structure. See also Figure 1 and Figure 2 The side pedal 5 is extended or retracted by the drive motor 23.

[0037] like Figure 3 and Figure 4 The active seat 2 includes a base 21, on which a movable groove 26 is provided. The drive shaft 24 of the drive motor 23 extends upward through the mounting plate 22 on the lower side of the movable groove 26. A first mounting hole 41 on one side of the connecting rod 4 is fixed on the drive shaft 24. A limit cover 25 is provided on the upper side of the drive shaft 24. The base 21 is mounted on the frame at the bottom of the vehicle.

[0038] More specifically, a bearing (not shown in the figure) may be installed on the upper side of the drive shaft 24; a limit cover 25 is installed on the outer ring of the bearing; and the inner ring of the bearing is installed on the drive shaft 24.

[0039] The first mounting seat 42 on the outer side of the other connecting rod 4 can be hinged to the second mounting hole 54 on the lower side of the base 21 via a bearing. The structure of the driven seat 3 is similar to that of the driving seat 2, but the drive motor is removed, and a driven shaft is provided on the mounting plate of the movable slot. The other connecting rod 4 is hinged to the driven shaft. For the remaining structure, please refer to the driving seat 2. This utility model will not be described in detail again.

[0040] In a specific control setup, the protective device also includes a control module 6, such as... Figure 7The control module 6 is connected to the pressure sensor 55, the built-in current sensor 231 of the drive motor 23, and the control terminal of the drive motor 23. The control module 6 is also connected to the door position sensor or door sensor switch to receive signals from the door opening and closing mechanism. The door position sensor or door sensor switch is mounted on the door; its installation method is existing technology and will not be described further in this invention. When the pressure sensor 55 detects a collision signal or the current sensor 231 detects a current overload, it determines that an obstacle collision has occurred and takes corresponding obstacle avoidance measures, such as stopping the action or taking the opposite action.

[0041] The control module 6 can use an STM32 microprocessor; the drive motor 23 can use a stepper motor; but it is not limited to these.

[0042] This invention uses a pressure sensor 55 and a current sensor 231 to detect the collision with obstacles. Based on this, it controls the drive motor 23 and the side pedal 5 to protect the car pedal 1, prevent further damage, improve safety and reliability, and enhance the user experience.

[0043] In this specific embodiment, a side-rotating car pedal 1 is used, which reduces the distance requirement to the bottom of the car and the possibility of collision with the ground compared to a swing-type car pedal. However, the protective measures of the side pedal 5 of this utility model can also be used with a swing-type car pedal. The specific structure of the swing-type car pedal and the pressure sensor 55 is prior art, and will not be described in detail here.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
