Detailed ways

In order to further understand the inventive content of the present invention, the present invention will be described in detail below with reference to specific embodiments.

The installation structure of the saddle of an electric vehicle as shown in Figures 1-2 includes a seat tube 1 and a connecting tube 2. The side wall of the seat tube 1 is provided with a chute 3, and the number of the chute 3 is two, two The chute 3 is symmetrically opened along the center line of the seat tube 1 , and a stud 4 is respectively provided in the two chute 3 . A fastening nut 5 is threadedly mounted on the column 4 , and the other end of the stud 4 is mounted on the side wall of the lower end of the connecting pipe 2 . The stud 4 can move up and down in the chute 3, so that when the connecting tube 2 moves up and down inside the seat tube 1, the stud 4 can move up and down at the same time, and the movement of the connecting tube 2 is limited to prevent it from being in the seat tube 1. When rotation occurs and the height of the saddle needs to be adjusted, first hold the two studs 4 and loosen the tightening nut 5 on the studs 4, so that the connecting tube 2 and the seat tube 1 can be moved relative to each other from the locked state state, and then move the connecting tube 2 up and down as needed. After moving to a suitable position, hold the stud 4 tightly, and fasten the tightening nut 5 on the side wall of the seat tube 1 to lock the seat tube 1 and the connecting tube 2. After the adjustment of the saddle position is completed, the length of the chute 3 and the installation position of the stud 4 on the connecting pipe 2 can be determined by those skilled in the art according to the actual situation.

A saddle mounting plate 6 is fixedly connected to the top of the connecting pipe 2 , and a saddle mounting hole 7 is opened on the saddle mounting plate 6 . The saddle mounting plate 6 is mounted on the connecting pipe 2 by welding. The saddle mounting plate 6 is used to connect the saddle. The saddle can be mounted on the saddle through the saddle mounting hole 7 on the saddle mounting plate 6 Mounting plate 6 to connect the saddle to the frame of the electric vehicle.

The side wall of the lower end of the connecting pipe 2 is provided with a threaded hole 1 8 , and one end of the stud 4 is threadedly installed in the threaded hole 1 8 . The connection method between the stud 4 and the connecting pipe 2 can be threaded connection. Specifically, a threaded hole 18 is opened at a suitable position at the lower end of the connecting pipe 2, and one end of the stud 4 is installed in the threaded hole 18 by means of threaded connection. The threaded connection also facilitates the assembly between the connecting tube 2 and the seat tube 1 , and the stud 4 can be installed after the connecting tube 2 is installed into the seat tube 1 .

The bottom of the seat tube 1 is provided with a bottom mounting seat 9 , a spring 10 is mounted on the upper surface of the bottom mounting seat 9 , and a top mounting seat 11 is mounted on the top of the spring 10 . Both ends of the spring 10 are respectively mounted on the top mounting seat 11 and the bottom mounting seat 9 by welding, and the spring 10 is installed inside the seat tube 1, so that the connecting tube 2 has a certain buffering performance during the downward movement, preventing After the tightening nut 5 is loosened, the connecting pipe 2 descends rapidly, causing damage to the saddle.

The bottom mounting seat 9 includes a base 12 and a base side wall 13 installed in the circumferential direction of the base 12. The outer diameter of the base side wall 13 is matched with the inner diameter of the seat tube 1, so that the base side wall 13 can just be installed on the base. 1, the side wall 13 of the base is provided with a second threaded hole 14, the seat tube 1 is provided with a countersunk hole 15 at a position corresponding to the second threaded hole 14, and a countersunk hole screw is installed in the countersunk hole 15, so The countersunk screw passes through the countersunk hole 15 and is threadedly connected with the second threaded hole 14 . The bottom mounting seat 9 is composed of a base 12 and a base side wall 13. The base side wall 13 is used to install the bottom mounting seat 9 on the bottom of the seat tube 1. The countersunk hole 15 can be connected with the countersunk hole 15 and the threaded hole 2 14 in turn with a countersunk screw to connect the seat tube 1 with the side wall 13 of the base, so that the spring 10 is installed in the seat tube 1. The hole is a countersunk hole 15 and is connected by a countersunk hole screw. Therefore, the connected countersunk hole screw is located in the countersunk hole 15 without protruding from the side wall of the seat tube 1, thereby facilitating the installation of the seat tube 1 on the frame.
