Embodiment Construction
[0025] The method of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0026] see Figure 1 ~ Figure 3 , the invention discloses an automatic separation system for a door hinge fixed support, comprising a door hinge fixed support 1, a first thrust bearing 2, an automatic separation support 3, a first preload spring 4, and a second preload spring 5. First spool valve 6, pin shaft 7, base outer shaft 8, base mandrel 9, second spool valve 10, angle sensor 11, base 12, nut 13, second thrust bearing 14, third thrust bearing 15 , Screw rod 16, the 4th thrust bearing 17, motor, collision sensor and controller.
[0027] Wherein the door hinge fixed support 1 is rigidly connected with the screw rod 16, and the right end of the screw rod 16 is provided with a nut 13; the first thrust bearing 2 is housed between the door hinge fixed support 1 and the automatic separation support 3; the automatic separation support 3 and...

The invention discloses an automatic separating system and method for an automobile hinge fixing support. The automatic separating system comprises an automatic separation support, a first pre-tightening force spring, a second pre-tightening force spring, a first sliding valve, a second sliding valve, a corner sensor, a base, a motor, a collision sensor and a controller. Under the normal situation, the automatic separation support is stopped through a pin shaft via a base outer shaft inclined shaft and cannot be separated from a base outer shaft; after an automobile is started, the controllercollects signals of the collision sensor in real time; and when collisions of the automobile are judged, the controller controls the motor to drive the automatic separation support to rotate anticlockwise, and then the pin shaft can rotate anticlockwise along the inclined groove in the base outer shaft. When the pin shaft rotates to be aligned with a long groove, horizontal restraints on the pin shaft from the base outer shaft disappear, the automatic separation support moves leftwards by a certain distance under the action of the first pre-tightening force spring and is separated from the base. By adoption of the automatic separating system and method, the problem that an automobile door cannot be normally opened during automobile door or automobile body deformation can be solved.
Description
technical field [0001] The invention relates to an automatic separation system and method for a fixed support of a door hinge. Background technique [0002] Door hinges and their fixings are very important parts in a car. The function of the hinge is to connect the door and the body, support the door so that the door is firmly hung on the body and allow the door to rotate around the hinge. The fixed support of the door hinge is an important device connecting the door hinge and the body. The force of the door on the hinge is transmitted to the body through the hinge fixing base, so it has higher requirements. [0003] In many traffic accidents, due to the large deformation of the body and the door during the collision, the door cannot be opened normally, so the occupants in the car will be injured twice or die due to lack of timely treatment. If a traffic accident occurs on the expressway, the traffic law stipulates that the driver should set up warning signs behind the car...
