[0026] The following combines the attached Figures 1-4 to further elaborate on this application.

[0027] The embodiments of this application disclose a backrest bracket for an electric vehicle. Refer to Figure 1 and Figure 4 , a backrest bracket for an electric vehicle, including a mounting frame 1; a lifting structure 2 is installed on the end face of the mounting frame 1;

[0028] The lifting structure 2 includes support outer cylinders 201 installed on the left and right sides of the end face of the mounting frame 1. A lifting inner rod 202 is slidably connected to the inner wall of the support outer cylinder 201. The two lifting inner rods 202 are connected by a fixing plate 203. A connecting groove 204 is opened on the lower side of the left lifting inner rod 202. A spring 205 is installed in the left lifting inner rod 202 through the connecting groove 204. The other end of the spring 205 is provided with a movable column 206. A limiting hole 207 is opened on the side wall of the left support outer cylinder 201. Press the movable column 206 into the connecting groove 204 so that the movable column 206 is not controlled by the limiting hole 207, and drive the lifting inner rod 202 to move up or down, realizing the function of adjusting the height of the backrest 4, solving the problem that the height of the backrest 4 of the backrest bracket of the existing battery vehicle cannot be adjusted and cannot be applied to people of different heights, thus meeting the comfort requirements of different people when sitting;

[0029] The fronts of the two support outer cylinders 201 are connected by a protection structure 3;

[0030] The protection structure 3 includes a support plate 301. U-shaped frames 302 are correspondingly installed on the front of the support plate 301 and located on the left and right sides. A first protection belt 303 is installed on the outer wall of the right U-shaped frame 302. The other end of the first protection belt 303 is installed with a female snap fastener 304. A second protection belt 305 is installed on the outer wall of the left U-shaped frame 302. The other end of the second protection belt 305 is connected with a male snap fastener 306. A storage box 307 is installed on the front of the support plate 301 and located on the lower side; The first protection belt 303 and the second protection belt 305 are used in cooperation to tie the waist of the rider. Through the cooperation between the second protection belt 305 and the male snap fastener 306, riders with different waist circumferences can be tied, realizing the protection function for children and sleeping passengers, solving the problem that the backrest bracket of the existing battery vehicle lacks a safety protection device and cannot ensure the riding safety of children and sleeping passengers, and ensuring the riding safety of the riders.

[0031] Refer to Figures 1-3 , the left lifting inner rod 202 is slidably connected to the outer wall of the movable column 206 through the connecting groove 204. Both support outer cylinders 201 are connected to the back of the support outer cylinder 201; A plurality of limiting holes 207 are opened and evenly distributed on the side wall of the left support outer cylinder 201; The support outer cylinder 201 is arranged in a quadrilateral sleeve structure, and the lifting inner rod 202 is adapted to the inner cavity of the support outer cylinder 201; By setting the lifting inner rod 202 to be adapted to the inner cavity of the support outer cylinder 201, the up and down sliding fit between the lifting inner rod 202 and the support outer cylinder 201 is tighter, so that the support outer cylinder 201 is more stable after the height adjustment is fixed;

[0032] Refer to Figures 1-3, the movable column 206 and the limiting hole 207 are set to be adapted to each other, and the left end of the movable column 206 is set to have a "hemispherical" structure; by setting the left end of the movable column 206 to have a "hemispherical" structure, it is convenient for the movable column 206 to leave the limiting hole 207 and slide in the inner cavity of the support outer cylinder 201, making the height adjustment more convenient;

[0033] Refer to Figure 4 , the fixing plate 203 is set to have an isosceles trapezoid structure, and the mounting frame 1 is set to have a "U" - shaped structure; the connection length between the second protective belt 305 and the sub - buckle 306 is set to be adjustable, and the support plate 301 and the support outer cylinder 201 are set to be perpendicular to each other; a backrest 4 is installed on the front of the fixing plate 203, the first mounting ears 5 are installed on the left and right side walls in the inner cavity of the mounting frame 1, and the second mounting ears 6 are installed on the back in the inner cavity of the mounting frame 1, and bolt holes 7 are provided on the second mounting ears 6 and bolt holes 7; by setting the connection length between the second protective belt 305 and the sub - buckle 306 to be adjustable, it is possible to tie passengers with different waist circumferences, realizing the function of protecting the passengers;

[0034] Working principle: By pressing the movable column 206 into the connection groove 204, the movable column 206 is not controlled by the limiting hole 207, driving the lifting inner rod 202 to move up or down on the inner wall of the support outer cylinder 201. When the height adjustment is completed, under the reset action of the spring 205, the movable column 206 is driven into its corresponding limiting hole 207 to fix the position of the lifting inner rod 202, realizing the function of adjusting the height of the backrest 4. By setting the lifting structure 2, the problem that the height of the backrest 4 of the existing backrest bracket of the battery vehicle cannot be adjusted and cannot be applied to people of different heights is solved, thus meeting the comfort requirements of different people when sitting;

[0035] The first protective belt 303 and the second protective belt 305 are used in combination to tie the waist of the passenger. The length of the second protective belt 305 is adjusted through the cooperation between the second protective belt 305 and the sub - buckle 306 according to the waist circumference of the passenger. Then, the sub - buckle 306 is inserted into the mother - buckle 304, which can tie passengers with different waist circumferences, realizing the protection function for children and sleeping passengers. By setting the protection structure 3, the problem that the existing backrest bracket of the battery vehicle lacks a safety protection device and cannot ensure the riding safety of children and sleeping passengers is solved, ensuring the riding safety of the passengers.
