Problems solved by technology
Although the structure is simple and feasible, the models in the existing market face a series of problems, such as: the manual operation force is too large, making it difficult for customers to manually open and close the door, and even for the elderly and teenagers, it is impossible to manually open or close the door. In some critical moments, the opening and closing of the car door determines the safety of life and property, so reasonable manual operation force will be the core of the competition in the car market

Embodiment Construction
[0027] see Figure 1 to Figure 4 , an electric back door opening and closing mechanism, comprising an outer cylinder 6 and an inner cylinder 12, one end of the inner cylinder is fixed to a sliding joint 13 for connecting the back door, and the other end of the inner cylinder extends into the outer cylinder to connect with the outer cylinder Sliding fit, the drive motor 5 is fixed inside the outer cylinder. The drive motor of the present implementation is fixed in the outer cylinder by the motor bracket 7 . The drive motor is connected with the screw rod 8 to drive the screw rod to rotate. The screw rod is threaded with a guide nut 11, and the guide nut drives the inner cylinder to slide axially in the outer cylinder. The guide nut is fixedly connected with the sliding joint. A spring 9 is sleeved on the guide nut. The spring is sleeved on the screw rod and the guide nut, one end of the spring is located in the outer cylinder, and the other end of the spring is located in th...

The invention relates to an optimization method for manual operation force of an opening and closing mechanism of an automobile electric back door. The friction clearance s of sliding fit of an inner drum and an outer drum of the opening and closing mechanism of the automobile electric back door is adjusted, and therefore the inner friction force of the mechanism is adjusted. The inner clearance s of the opening and closing mechanism of the automobile electric back door is verified and optimized through experimental verification and test data processing, and therefore when the opening and closing mechanism of the electric back door executes manual operation, the manual operation force F<h> is smaller than or equal to 100 N, and the manual operation force of the opening and closing mechanism of the automobile electric back door is reasonable.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a method for optimizing the manual operating force of an opening and closing mechanism of an electric rear door of an automobile. Background technique [0002] At present, most of the back doors of automobiles use a rotating pair structure fixed on the top of the vehicle to realize the rotary opening and closing of the door. The connection realizes the opening and closing of the car door through the rotation of the drive motor. Although the structure is simple and feasible, the models in the existing market face a series of problems, such as: the manual operation force is too large, making it difficult for customers to manually open and close the door, and even for the elderly and teenagers, it is impossible to manually open or close the door. In some critical moments, the opening and closing of the car door determines the safety of life and property, so reasonable manual ope...
