Description

Technical Field

[0001] The utility model relates to the field of anti-collision structures, in particular to an anti-collision structure for a vehicle window motor. Background Art

[0002] The window motor is the power drive device of the electric window. It drives the glass lifter motor through the on-board power supply, making the lifter move up and down, thereby driving the window glass to move up and down, realizing automatic opening and closing of the window. This design allows the driver or passenger to sit conveniently in the seat and use the switch to automatically lift the door glass. It is not only easy to operate, but also conducive to driving safety. It has become the first choice for modern car window design. Existing window motors are usually directly embedded in the door. In the event of a collision, it is easy to cause damage to the motor, resulting in the inability to lift the window. Once the motor is started, it will continue to rise, which is easy to cause safety accidents when encountering obstacles. Utility Model Content

By setting up a Hall sensor and a current sensor, it is possible to detect whether the window encounters an obstacle by detecting the rotation speed of the motor body shaft and the change of the motor body current respectively, so that measures can be taken in time to control the lifting and lowering of the window to avoid safety accidents. Under the dual action of the Hall sensor and the current sensor, the detection effect is more accurate and the anti-collision effect is better.

[0006] Preferably, the motor assembly includes a motor body, a power transmission module, a Hall sensor and a current sensor. The right end of the motor body is detachably connected to the power transmission module for transmitting power by four groups of surrounding bolts.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional window motor, which is usually directly embedded in the door, it is easy to cause the motor to be damaged and the window cannot be raised or lowered in the event of a collision. Once the motor is started, it will continue to rise, which is easy to cause a safety accident when encountering an obstacle. By setting the first anti-collision component, the second anti-collision component and the third anti-collision component, different parts of the motor component can be protected respectively, so that it can play an anti-collision role when the window collides, so that the internal motor component is not easy to be damaged. The first anti-collision component can be used to protect the motor body. By setting the first protective cover with the first protective layer, it can play a preliminary protection role. By setting the second protective cover on the outside of the first protective cover, the motor body can be further protected. By setting a spring between the first protective cover and the second protective cover, the elasticity of the spring can be used to play a certain buffering role in the event of a collision, thereby playing a shock absorbing role. By fitting an elastic sheet in the middle of the inner and outer sides of the second protective cover, the elastic effect of the elastic sheet can be used to protect the second protective cover, so that it is not easy to be damaged, so that the protection effect of the second protective cover is better. The first protective cover and the second protective cover are used for double protection and the spring is used for buffering and shock absorption, so that the protection effect of the first anti-collision component is better.

[0014] 2. The end of the motor body can be protected by setting a second anti-collision component, and the end of the motor body can be covered by setting a protective cover, so as to protect the Hall sensor and the current sensor at the end of the motor body, which can greatly reduce the possibility of the Hall sensor and the current sensor being damaged due to collision. The protective cover and the first anti-collision component are detachably connected through the second fixing frame and the first fixing frame, so that the stability of the two can be maintained and the removal, maintenance or replacement of the protective cover can be facilitated. The power transmission module can be protected from the rear end by setting a third anti-collision component. The first protective plate with a second protective layer can play a preliminary protection role. The shock absorber can be provided for buffering protection, so that when a collision occurs, the first protective plate, the second protective plate and the shock absorber can cooperate with each other to play a role in buffering and shock reduction. Under the action of the first anti-collision component, the second anti-collision component and the third anti-collision component, the motor component can be provided with multi-directional anti-collision protection, so that the motor component is not easily damaged when a collision occurs. By providing a Hall sensor and a current sensor, it is possible to detect whether the window encounters an obstacle by detecting the rotation speed of the motor body shaft and the change of the motor body current respectively, so that timely measures can be taken to control the lifting and lowering of the window to avoid safety accidents. Under the dual action of the Hall sensor and the current sensor, the detection effect is more accurate and the anti-collision effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
