DETAILED DESCRIPTION

[0016] The electric tricycle portable spare tire frame of the present application is described below in conjunction with the accompanying drawings.

[0017] In the first embodiment of the present application, as shown in Figure 1 and Figure 2 , the electric tricycle portable spare tire frame (hereinafter referred to as "the present application") comprises a rotating pin 1, a U-shaped fixed plate 2, a spare tire bracket 3, a positioning pin 4, and a reset spring 5. Two U-shaped fixed plates 2 are fixedly installed at the lower part of the vehicle frame. The front part of the spare tire bracket 3 is hinged to the U-shaped fixed plate 2 through the rotating pin 1. The spare tire 11 is installed on the spare tire bracket 3 through the fastening nut 10. The spare tire bracket 3 has a waist-shaped hole formed through the side edge. The stress rod 12 passes through the waist-shaped hole of the spare tire bracket 3. One end of the reset spring 5 is installed on the inside of the spare tire bracket 3 towards the front part through the positioning pin 4. The other end of the reset spring 5 is hinged to the stress rod 12 through the limit pin I 6. The inside of the spare tire bracket 3 is provided with a force transmission bracket 8. The stress rod 12 is hinged to one end of the force transmission bracket 8 through the limit pin I 6. The lifting connecting rod 14 has its two ends hinged to the other end of the force transmission bracket 8 through the limit pin II 7. The lifting bracket 9 is fixedly installed on the carriage rear bracket 15. The upper and lower surfaces of the spare tire bracket 3 are provided with waist-shaped holes for the limit pin I 6 and the limit pin II 7 to slide back and forth.

[0018] The hanging mechanism for the automobile spare tire lifter assembly (hereinafter referred to as "the patent") of the utility model patent No. CN211765919U prevents the steel cable from damaging the wheel hub by adding a sheath and other equipment. However, the installation method of the patent itself still suspends the spare tire under the vehicle through hinges and steel cables. However, this hoisting method requires the driver to quickly rotate the winch, then slowly lower the spare tire through the steel cable, then loosen the fixed screw, and finally replace the spare tire. This method is stable in hanging, but the operation is complicated and inconvenient to use. The present application pushes the force transmission bracket 8 and the lifting connecting rod 14 through the stress rod 12, so that the lifting connecting rod 14 is separated from the lifting bracket 9, the spare tire bracket 3 is unlocked and falls to the ground, the overall operation is simple, and the storage and retrieval of the spare tire are convenient.

[0019] The second embodiment is basically the same as the first embodiment, except that, as shown in Figure 1 , the stress rod 12 has rubber sheaths 13 sleeved at its two ends. This protects the stress rod 12 and improves the grip.

[0020] In order to further optimize the work efficiency of the application, the inside of the spare tire bracket 3 is coated with lubricating oil to make the sliding of the force transmission bracket 8 more smooth. In order to make the spare tire 11 more stable, a spare tire tray is installed on the spare tire bracket 3. In order to improve the strength of the spare tire bracket 3, the thickness of the square tube used in the spare tire bracket 3 is not less than three millimeters.

[0021] When in use, the portable spare tire frame of the electric tricycle is installed, and the device can be put into use.

[0022] The utility model in use, the specific work is as follows:

[0023] For the first time, the spare tire 11 is placed on the spare tire bracket 3 and fixed by tightening the fastening nut 10, and a upward lifting force is applied to the stress rod 12. The spare tire bracket 3 will make a circular motion along the rotating pin 1 of the U-shaped fixed plate 2. In this process, when the lifting connecting rod 14 contacts the outer arc surface of the lifting bracket 9, the lifting connecting rod 14 is forced to retract backward, and the force is transmitted to the reset spring 5 through the force transmission bracket 8 and the stress rod 12, so that the reset spring 5 is compressed, and the lifting connecting rod 14 moves backward. When the lifting connecting rod 14 moves to the top of the lifting bracket 9, the lifting connecting rod 14 has no compression force, the stress of the reset spring 5 is released, the lifting connecting rod 14 returns to the original position, the lifting bracket 9 holds the lifting connecting rod 14, and the locking operation is completed.

[0024] Enable the spare tire: apply a backward force to the stress rod 12, and the stress rod 12 transmits the force to the lifting connecting rod 14 through the limiting pin 1, the limiting pin 2 and the force transmission bracket 8, so that the lifting connecting rod 14 is separated from the lifting bracket 9. Under the action of gravity, the rotating pin 1 of the U-shaped fixed plate 2 rotates and falls downward. Remove the fastening nut 10 and take out the spare tire to complete the operation.

[0025] When in use, if one side of the force transmission bracket 8 is not linked, just push the stress rod 12 on the other side of the vehicle.

[0026] In summary, the portable spare tire frame of the electric tricycle of the utility model embodiment can carry the spare tire 11 by installing the spare tire bracket 3 under the frame, and can carry the spare tire while ensuring the structural strength of the frame. At the same time, the stress rod 12 pushes the force transmission bracket 8 and the lifting connecting rod 14, so that the lifting connecting rod 14 is separated from the lifting bracket 9, the spare tire bracket 3 is unlocked and falls to the ground, and the storage and retrieval of the spare tire is simple and convenient.

[0027] Those skilled in the art should understand that the above discussion of any embodiment is only exemplary, and is not intended to suggest that the present application is limited to these examples; under the idea of the present application, the above embodiments or technical features among different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for the sake of brevity. Any omission, modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
