[0028] like Figures 1 to 3 As shown, the child safety seat of the present invention includes a seat body 100, a front and rear adjustment mechanism 2 and a mounting seat 3, the seat body 100 includes a seat plate 11 and a back plate 12, the back plate 12 and the seat plate 11 are rotatably connected, the front and rear adjustment mechanism 2 includes a fixed lower plate 21 and a movable upper plate 22, the movable upper plate 22 is fixedly connected to the bottom surface of the seat plate 11, the movable upper plate 22 is slidably connected to the top surface of the fixed lower plate 21, an adjustment component 23 for adjusting the front and rear position of the movable upper plate 22 is arranged between the fixed lower plate 21 and the movable upper plate 22, the mounting seat 3 is arranged below the front and rear adjustment mechanism 2, a shock absorbing component 4 is arranged between the mounting seat 3 and the front and rear adjustment mechanism 2, and the mounting seat 3 is installed on the battery vehicle.

[0029] The mounting seat 3 enables the child safety seat to be installed on the battery vehicle. The front and rear adjustment mechanism 2 and the shock absorbing assembly 4 allow the child safety seat to have adjustment and shock absorbing functions to adapt to the bumpy usage environment of the battery vehicle. The position of the seat body 100 can be adjusted front and rear in the limited position of the battery vehicle, so that the child has enough space for his legs when sleeping or sitting.

[0030] Exemplarily, a slide groove 221 is provided on the bottom surface of the movable upper plate 22 along the front-to-back direction of the electric vehicle, and the fixed lower plate 21 is provided with a slide rail 211 cooperating with the slide groove 221. The slide rail 211 is slidably connected to the slide groove 221. The cooperation between the slide groove 221 and the slide rail 211 has a guiding effect on the position adjustment of the seat body 100, so that the position of the seat body 100 can be moved along the front-to-back direction of the electric vehicle. When the child is sleeping, the seat body 100 can be moved forward and the back plate 12 can be rotated to an inclined angle so that the back plate 12 has enough position to rotate. When the child needs to sit, the seat can be moved backward to allow the child's legs to have enough space and be more comfortable when sitting.

[0031] In other embodiments, the slide groove 221 may be opened in the fixed lower plate 21, and the slide rail 211 may be set on the upper plate. T-shaped grooves may be used to allow the slide rail 211 and the slide groove 221 to limit each other to prevent them from falling out.

[0032] Exemplarily, the adjustment assembly 23 includes an adjusting screw 231, which passes through the movable upper plate 22. The adjusting screw 231 and the movable upper plate 22 are threadedly connected to form a screw-nut pair between the adjusting screw 231 and the movable upper plate 22. The direction of the adjusting screw 231 is parallel to the direction of the slide groove 221. Through the screw-nut pair formed by the adjusting screw 231 and the movable upper plate 22, the position of the movable upper plate 22 can be adjusted by rotating the adjusting screw 231. Specifically, a knob 232 is provided on the adjusting screw 231, and the knob 232 is used to facilitate the rotation of the adjusting screw 231 to allow the movable upper plate 22 to move forward and backward, thereby driving the seat body 100 to move forward and backward to adjust its position.

[0033] In other embodiments, two mutually cooperating slide grooves 221 and slide rails 211 can be respectively set on both sides of the movable upper plate 22 and the fixed lower plate 21, and the adjusting screw rod 231 can be set in the middle to make the force more balanced. In addition, the two slide grooves 221 and the slide rails 211 have better guiding effects and are not easy to shift.

[0034] Exemplarily, the shock absorbing assembly 4 includes a spring seat 24 and a shock absorbing spring 25, and several of the spring seats 24 are evenly distributed on the mounting seat 3.

When the electric vehicle is traveling in a bumpy environment, the shock absorbing spring 25 switches between a compressed and stretched state. When the shock absorbing spring 25 undergoes elastic deformation, the elastic force will restore the shock absorbing spring 25 to its original state. Therefore, when the shock absorbing spring 25 is stretched, the direction of the elastic force pulls the fixed lower plate 21 inward, and when the shock absorbing spring 25 is compressed, the direction of the elastic force pushes the fixed lower plate 21 outward. The vibration amplitude of the fixed lower plate 21 is reduced by the shock absorbing spring 25 to achieve a shock absorbing effect.

[0035] Exemplarily, downwardly extending lower extension plates 31 are provided on both sides of the mounting seat 3, and mounting holes 32 for mounting the mounting seat 3 are opened on the lower extension plates 31. The lower extension plates 31 are connected to the body of the battery vehicle through connecting parts, and the mounting seat 3 is installed on the battery vehicle.

The mounting holes 32 allow the mounting seat 3 to be fixed to the battery vehicle by bolts, so that the mounting seat 3 is fixed.

[0036] Exemplarily, the bottom surface of the mounting seat 3 is evenly provided with anti-loosening springs 33, and the lower ends of the anti-loosening springs 33 are connected to anti-slip feet 34, which prevent the mounting seat 3 from shifting on the battery vehicle and preventing loosening.

[0037] Exemplarily, the anti-loosening spring 33 is in a compressed state so that the anti-slip foot 34 presses against the battery vehicle, preventing the connection piece from having loose space, and allowing the mounting base 3 to be more firmly mounted on the battery vehicle.

[0038] Exemplarily, the movable upper plate 22 is detachably connected to mounting plates 26 on both sides, and a plurality of plug rods 27 are provided on the mounting plates 26.
