Description

Technical Field

[0001] The invention relates to the technical field of anti-collision automobile pedals, in particular to an adaptive telescopic anti-collision automobile pedal and a use method thereof. Background Art

[0002] The adaptive retractable anti-collision car pedal is a high-tech automotive accessory designed to improve the safety and convenience of the vehicle. This accessory realizes the automatic retractable function of the pedal through the coordinated work of the induction switch, motor and retractable component. The retractable action of the pedal is controlled by an intelligent system, which responds quickly and is easy to operate.

[0003] The adaptive retractable anti-collision car pedal can provide convenient assistance for getting on and off the car. It can also automatically retract when an obstacle is detected or it is not needed to avoid potential collisions and damage. When used at night, the fluorescent strip on the top of the pedal provides lighting to increase safety. Adaptive telescopic anti-collision automobile pedals are usually located at the bottom or side of the vehicle, which are easy to come into contact with the ground during driving, especially when driving off-road or on muddy roads. On slippery or muddy roads, water and mud are easy to adhere to the tire surface. When the wheel rotates, the water and mud on the tire are thrown off the tire surface by the centrifugal force and are more likely to come into contact with mud and sand.

[0014] S1: When the door is opened, the pedal receives the signal from the sensor to control the extension or retraction of the telescopic component. At the same time, the pedal will automatically sense and extend. During the extension or retraction process of the pedal, if the sensor detects an obstacle, the system will automatically stop the pedal to avoid collision. S2: Before using the pedal, first install the protective device inside the installation groove set on the pedal body. During installation, first install the set installation pin by pressing one end of the installation pin and the extrusion spring. When the set installation block is installed inside the installation groove, when the set installation pin corresponds to the installation hole, the installation pin will enter the inside of the installation hole through the elastic force of the spring for fixed installation; S3: When the door is opened, the pedal receives the signal from the sensor to control the extension or contraction of the telescopic component. At the same time, the sensor signal controls the motor to operate through the control circuit. The motor controls the rotating rod and the gear to rotate. The rotation of the gear will drive the rack and the drive plate to rotate at a certain angle, and drive the adjustment plate to rotate clockwise. When the pedal is extended and retracted, the adjustment plate will be parallel to the pedal. At this time, the adjustment plate can effectively extend the length of the pedal. The extended pedal can provide a more stable support point, reducing the difficulty and risk of getting on and off the vehicle. S4: After the passengers get on and off the vehicle, when the door is closed, the pedal will automatically retract. During the retraction process, the sensor signal controls the motor through the control circuit, and the motor controls the adjustment plate to rotate counterclockwise. When the pedal is fully retracted, the adjustment plate will rotate a certain angle, so as to effectively protect the pedal and the telescopic component. At the same time, the sealing strip at one end of the adjustment plate will fit tightly against the vehicle body to prevent splashed water and mud from adhering to the pedal and the telescopic component, and premature wear of the pedal and its telescopic mechanism, which will affect the normal extension and retraction of the pedal. The drainage column can effectively drain the accumulated water from the pedal surface, avoid the risk of slipping due to water accumulation on the pedal surface, and increase friction. The mudguard and the anti-collision pad body can reduce the splashing of mud and water onto the pedal surface, prevent mud and sand from entering the telescopic component of the car for corrosion, and ensure the normal extension and retraction of the pedal.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by means of the protective device, when the pedal is extended, the adjustment plate rotates clockwise under the control of the motor to be parallel to the pedal, extending the length of the pedal and providing a more stable support point. When the door is closed and the pedal is retracted, the adjustment plate rotates counterclockwise to effectively protect the pedal and the telescopic component. The provided sealing strip can be closely attached to the vehicle body to prevent water stains and sludge from adhering to the surface of the pedal and the telescopic component, effectively preventing the accumulated substances from affecting the normal extension and retraction of the pedal; 2. In the present invention, the installation of the protective device is more stable through the cooperation of the multiple installation holes and the installation slots. During installation, the installation block can be easily installed in the installation slot by squeezing the spring and the installation pin. When the installation pin corresponds to the installation hole, the spring force causes the installation pin to enter the installation hole, thereby achieving rapid fixation. 3. In the present invention, the drainage column can quickly drain the surface water of the pedal, reducing the risk of slipping. The friction holes on the outside further increase the friction force, providing safer support for passengers to get on and off the vehicle. The anti-collision pad can effectively reduce the impact force of splashing stones, ensuring a more stable structure. 4. In the present invention, the fender is arranged in a wave shape, which can effectively prevent mud and water from splashing onto the pedal and the telescopic assembly, prevent sediment erosion, extend the service life of the pedal and the telescopic assembly, and provide comprehensive protection for the pedal and the telescopic assembly when the door is opened and closed.
