Problems solved by technology
However, the cost of torsion bar power assist is low, the performance is relatively general, and the scope of application is narrow; the combined mechanism of gas spring and four-link is used in higher-level cars, and the performance is better, but the cost is also high, and the scope of application is limited. The remote control power-assisted mechanism with high technical content can work in conjunction with various motion actuators, with the best performance and the highest cost. It is only used in high-end cars, and the scope of application is the most limited.

Embodiment Construction
[0019] figure 1 It is a structural schematic diagram of the closed state of the trunk lid in the present invention, figure 2 It is a structural schematic diagram of the open state of the trunk lid in the present invention, image 3 is a design flowchart of the design method for the trunk lid opening mechanism. Depend on Figure 1-Figure 3 Combining the shown structures, it can be seen that this kind of trunk lid opening mechanism includes an arc-shaped moving bracket 2 fixed on the trunk lid 1 and a driving device. The driving device is fixed on the vehicle body, and the arc-shaped moving bracket 2 The other end passes through the sheet metal parts on the car and is fixed on the driving device. The driving device is driven by the motor, and the motor starts to work through the signal sent by the remote control key. The driving device drives the arc-shaped motion bracket 2 to move, and the arc-shaped motion bracket 2 drives the trunk lid 1 to open and close.

The invention discloses a trunk lid opening mechanism and a design method thereof. The trunk lid opening mechanism comprises an arc moving bracket with one end being fixed on a trunk lid and a driving device, wherein the driving device is fixed on an automobile body; the other end of the arc moving bracket penetrates through a sheet metal part on the automobile body and is fixed on the driving device; the driving device drives the arc moving bracket to move; the arc moving bracket drives the trunk lid to open and close; the cross section of the arc moving bracket is circular; a circular hole which is convenient for the arc moving bracket to pass through and can not interfere the arc moving bracket is formed on the sheet metal part; and the diameter of the circular hole is less than 1CM larger than that of the arc moving bracket. The trunk lid opening mechanism with the structure and the design method thereof can determine design boundaries according to specific vehicle models, meet the requirements of various vehicle models and improve the normal operational performance, and simultaneously the circular hole formed on the sheet metal part can ensure that the arc moving bracket can not be interfered during the moving process.
Description
technical field [0001] The invention relates to the field of vehicle engineering, in particular to a trunk lid opening mechanism and a related method. Background technique [0002] At present, there are various booster mechanisms for opening the trunk lid or back door on the market, among which the more common booster mechanisms include gas springs, torsion bars, motors, etc., and the more common motion actuators include four-bar linkages and crank-connecting rods. Wait. However, the cost of torsion bar power assist is low, the performance is relatively general, and the scope of application is narrow; the combined mechanism of gas spring and four-link is used in higher-level cars, and the performance is better, but the cost is also high, and the scope of application is limited. The remote control power-assisted mechanism with high technical content can work jointly with various motion actuators, which has the best performance and the highest cost. It is only used in high-en...
