Tail door anti-collision system

Abstract

The invention relates to the technical field of tail doors, in particular to a tail door anti-collision system. The tail door anti-collision system comprises a distance measuring inductor, a controller and a drive motor. The distance measuring inductor can horizontally transmit distance measuring signals to the rear portion of a vehicle, and the horizontal distance between a tail door and an obstacle behind the vehicle is measured and calculated. Through the arrangement, in the vehicle tail door opening process, the phenomenon that the tail door is likely to collide with buildings and other obstacles near the carport, and consequently vehicle damage is caused is prevented, and tail door opening is more intelligent and reliable. The drive motor is provided with a hall sensor used for monitoring the rotation speed and the stroke of the drive motor, and when the distance measuring sensor misses detection or mistakenly conducts detection, the hall sensor can monitor the change of a drive electrode in time, and when collisions happen to the tail door, the hall sensor can immediately send data to the controller, then, the controller is used for controlling the drive motor to stop working, and serious collisions of the tail door are avoided.

Description

technical field [0001] The invention relates to the technical field of tailgates, in particular to an anti-collision system for tailgates. Background technique [0002] In the prior art, during the opening process of the tailgate (including the tailgate) of the vehicle, it is easy to happen when the electric switch is directly pressed to open the tailgate due to the small space behind the vehicle or the small space on the top of the vehicle. Colliding with an obstacle at the rear or colliding with an obstacle above the vehicle, causing damage to the vehicle. Especially for medium and large vehicles such as medium-sized SUVs, large SUVs or crossovers, during the process of automatically opening the tailgate, it is easy for the tailgate to collide with obstacles due to the narrow parking lot or parking space. [0003] Although the automatic tailgate of the vehicle in the prior art will stop immediately after hitting an obstacle during the opening process, the paint or other v...

[0002] In the prior art, during the opening process of the tailgate (including the tailgate) of the vehicle, it is easy to happen when the electric switch is directly pressed to open the tailgate due to the small space behind the vehicle or the small space on the top of the vehicle. Colliding with an obstacle at the rear or colliding with an obstacle above the vehicle, causing damage to the vehicle

Especially for medium and large vehicles such as medium-sized SUVs, large SUVs or crossovers, when the tailgate is automatically opened, it is easy for the tailgate to collide with obstacles due to the small parking lot or parking space.

[0003] Although the automatic tailgate of the vehicle in the prior art will stop immediately after hitting an obstacle during the opening process, the paint or other vulnerable parts on the tailgate have rubbed against the obstacle. collision, causing damage, affecting the appearance of the vehicle or the realization of some functions
