Description
Technical Field
[0001] The present application relates to the field of folding automobile tailgates, and more specifically to a pure electric folding automobile tailgate with folding assistance. Background Art
[0002] With the development of my country's logistics industry, the demand for tailgate installation on vehicles is growing. Most of the existing car tailgates use hydraulic systems, which have problems such as difficult maintenance, "running", "bubbling", "dripping", "leaking", and low-temperature freezing of oil. Domestic car tailgates are mainly cantilever-type, while folding car tailgates have been widely used in Europe and the United States. The tailgate bearing platform is relatively heavy, and it often requires the assistance of multiple people when folding, which is laborious and labor-intensive. Using electric push rods instead of hydraulic push rods can solve the problems of "running", "bubbling", "dripping" and "leaking". However, if the electric push rod is subjected to too much force when the tailgate is folded, the service life of the electric push rod will be greatly reduced. At the same time, if the force is too large, the tailgate cannot be flipped and folded, and an electric push rod with larger thrust will be required to increase the manufacturing cost of the product. Therefore, how to significantly reduce the flipping force required for folding is the key to effectively improving the service life of the electric push rod and reducing the cost of the product. In addition, if the vehicle is folding the car tailgate during the process, it is also more likely to vibrate, and reducing the vibration of the folding car tailgate can also greatly improve the service life of the product.
[0003] Therefore, there is a need to provide a pure electric folding automobile tailgate with folding assistance, which can significantly reduce the turning force required for folding, prevent the folding portion from vibrating during vehicle driving, and make unfolding more convenient and quick.

[0051] Among them, when the platform rear part 07 is folded upward to about 90°, the torsion spring 20 is in its original state. If the platform rear part 07 continues to fold at this time, the compressed part 2222 of the torsion spring 20 is separated from the platform rear part 07; if the platform rear part 07 is unfolded downward at this time, the torsion spring 20 needs to be twisted. The torsion spring 20 can provide supporting force to reduce the downward flipping force when the platform rear part 07 is unfolded. At the same time, the torsion spring 20 stores elastic potential energy to provide assistance for the platform rear part 07 to fold upward.
[0052] like Fig.15 As shown, a buffer wheel 16 is also provided on one side of the lifting seat 06, that is, the sixth connecting plate 063 located on the outside cooperates with the buffer wheel 16, that is, when the above-mentioned platform descends, the buffer wheel 16 touches the ground first, and a supporting foot 18 is also provided on the front side of the rear part 07 of the platform, wherein the height of the supporting foot 18 is adjustable to adapt to the situation where the ground has a slope.

When the rear part 07 of the platform tilts downward and lands, the supporting foot 18 is nearly vertical to the ground.
[0053] Among them, a guide rod mounting rod 12 is fixedly welded on the frame 02, and a guide rod component 09 is also provided at the end of the guide rod mounting rod 12 away from the frame 02. Specifically, the guide rod component 09 is fixedly mounted on the guide rod mounting rod 12 by bolts, and a plurality of mounting holes are provided on the guide rod component 09 so that its mounting position can be adjusted. A guide wheel 13 is provided at the front end of the guide rod component 09, and the outer edge of the guide wheel is exposed on the upper and right sides of the guide rod component 09.
[0054] In addition, a micro switch 10 is provided on the right side of the top of the hanging plate 0101, and an elastic stopper 11 is provided on the right side of the middle part. The elastic stopper 11 is an elastic element, and a folding stopper 14 is fixedly installed on the lifting arm 0303. The upper surface of the folding stopper 14 is designed to be inclined, so that the bearing platform can fit well with it after being folded. The folding stopper 14 is made of wear-resistant and self-lubricating materials.
[0055] The following is an explanation of the operating principle of this product: Fig. 9 As shown, when the platform is folded, the platform front part 08 is first folded in half and placed above the platform rear part 07. Then continue to fold the platform front part 08 and the platform rear part 07 together and flip it upward until the platform front part 08 abuts against the guide wheel, as shown in FIG. Fig.10 At this time, the guide wheel and the front part of the platform 08 are in rolling contact, and due to the gravity of the platform, the two will always be in contact. Then the tailgate of the car controls the electric push rod 0505 to extend, and the platform is driven to rise through the mechanism while continuing to fold until the front part of the platform 08 abuts on the folding block 14. Fig.11 At this time, as the electric push rod 05 extends, the lifting arm 0303 flips upward, the folding block 14 abuts against the front part of the folding platform 08 and flips upward, and the front part of the platform 08 separates from the guide wheel. In the subsequent rising process, the angle between the platform and the lifting arm 03 remains unchanged until it rises to the rear part of the platform 07 and pushes the micro switch. The system controls the electric push rod 05 to stop extending and completes the folding of the platform. At this time, Fig.12 shown.
[0056] like Fig.12 As shown, when the platform is folded into place, the rear of the platform front part 08 will squeeze the elastic stopper 11, and the elastic stopper will have a reverse thrust F on it. Since the line of action of this force is on the lower side of the hinge point O between the platform front part 08 and the platform rear part 07, it will press the platform front part 08 against the platform rear part 07. Since the line of action of force F is also on the lower side of the platform shaft 17, it will press the platform against the folding stopper 14 of the lifting arm 03, and at the same time provide a pre-tightening force for the moving parts of the tailgate relative to the frame 02, which can effectively prevent the platform front part 08, the platform rear part 07 and other moving parts from vibrating with each other and relative to the frame 02 after the tailgate is folded, reduce the possibility of wear and damage to components, and increase the service life of the whole machine.
[0057] In summary, the pure electric folding automobile tailgate with folding assistance based on the embodiment of the present application is explained, which provides the pure electric folding automobile tailgate with folding assistance with advantages such as greatly reducing the turning force required for folding, the folding part will not vibrate during vehicle driving, and the unfolding is more convenient and quick, etc.
