Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] To solve technical problems, such as Figure 1-5 As shown, the following preferred technical solutions are provided:

[0020] An electric shopping cart with an anti-collision function comprises a shopping cart body 1, a front bracket 2 is fixedly connected to the left and right sides of the front end surface of the shopping cart body 1, a slide groove 3 is provided on the upper end surface of the front bracket 2, a connecting rod 4 is slidably connected inside the slide groove 3, a first buffer spring 5 is abutted against the rear end surface of the connecting rod 4, the rear end of the first buffer spring 5 is fixedly connected to the inner rear end surface of the slide groove 3, and a shopping basket 6 is fixedly connected to the upper end surface of the connecting rod 4. When the user uses the shopping cart body 1, when the shopping basket 6 at the front end of the shopping cart body 1 collides with an object, the connecting rod 4 at the lower end of the shopping basket 6 retracts toward the inside of the slide groove 3 during the force application, and the shopping cart body 1 is buffered under the action of the first buffer spring 5 to prevent the shopping cart body 1 from being damaged.

[0021] Furthermore, a limiting groove 7 is provided at the left end of the connecting rod 4, and a limiting rod 8 is slidably connected inside the limiting groove 7. A handle 9 is fixedly connected to the left end surface of the limiting rod 8. The user pulls the handle 9 to drive the limiting rod 8 to disengage from the inside of the limiting groove 7, so that the connecting rod 4 is released and can be out of the range of the slide groove 3 to disassemble the shopping basket 6. When the user needs to install the shopping basket 6, the handle 9 is pulled outward, and the connecting rod 4 at the bottom of the shopping basket 6 is aligned with the position of the slide groove 3 and inserted to a certain position. Then, the handle 9 is pushed to drive the limiting rod 8 to insert into the inside of the limiting groove 7 to fix the shopping basket 6, which is convenient for replacing the damaged shopping basket 6.

[0022] Furthermore, a return spring 10 is fixedly connected to the right end of the handle 9, and the top end of the return spring 10 is fixedly connected to the left end surface of the front bracket 2. The user pulls the handle 9 to drive the limit rod 8 to disengage from the inside of the limit groove 7, so that the connecting rod 4 is released and can be out of the range of the slide groove 3 to disassemble the shopping basket 6. When the user needs to install the shopping basket 6, the handle 9 is pulled outward, and the return spring 10 accumulates force. After the connecting rod 4 at the bottom of the shopping basket 6 is aligned with the position of the slide groove 3 and inserted to a certain position, the handle 9 is released, and the limit rod 8 is automatically driven to insert into the inside of the limit groove 7 under the action of the return spring 10 to fix the shopping basket 6.

[0023] Furthermore, a mounting plate 11 is fixedly connected to the rear end surface of the shopping cart body 1, and a top plate 12 is abutted on the upper end surface of the mounting plate 11. A threaded rod 13 is fixedly connected to the upper end surface of the top plate 12. A connecting plate 14 is threadedly connected to the surface of the threaded rod 13. A rear baffle 15 is fixedly connected to the rear end surface of the connecting plate 14. A knob 16 is fixedly connected to the upper end of the threaded rod 13. A fixing plate 17 is fixedly connected to the lower front end surface of the rear baffle 15. The user drives the threaded rod 13 to move downward by rotating the knob 16, so that the distance between the threaded rod 13 and the fixing plate 17 becomes smaller. After moving downward for a certain distance, the lower end of the top plate 12 at the bottom end of the threaded rod 13 abuts against the upper end of the mounting plate 11, and the upper end of the rear baffle 15 abuts against the lower end of the mounting plate 11, so that the rear baffle 15 is fixed to the rear end of the shopping cart body 1 to prevent the rear objects from colliding with the rear end of the shopping cart body 1 and causing damage.

[0024] Furthermore, a non-slip pad 18 is fixedly connected to the lower end surface of the top plate 12, and the lower end surface of the non-slip pad 18 is fixedly connected to the upper end surface of the mounting plate 11. The user drives the threaded rod 13 to move downward by rotating the knob 16, so that the distance between the threaded rod 13 and the fixing plate 17 becomes smaller. After moving down a certain distance, the lower end of the non-slip pad 18 at the bottom end of the top plate 12 abuts against the upper end of the mounting plate 11, so that the fixation of the rear baffle 15 to the shopping cart body 1 is more stably.

[0025] Furthermore, a second buffer spring 19 is fixedly connected to the middle surface of the rear end of the tailgate 15, and an anti-collision plate 20 is fixedly connected to the top end of the second buffer spring 19. The user drives the threaded rod 13 to move downward by rotating the knob 16, so that the distance between the threaded rod 13 and the fixed plate 17 becomes smaller. After moving down a certain distance, the lower end of the anti-slip gasket 18 at the bottom end of the top plate 12 abuts against the upper end of the mounting plate 11, and the tailgate 15 is fixed to the rear end of the shopping cart body 1. When the rear vehicle collides with the front vehicle, the second buffer spring 19 at the front end of the anti-collision plate 20 buffers the impact force, thereby reducing damage to both parties.

[0026] In summary, when the user is using the shopping cart body 1, when the shopping basket 6 at the front end of the shopping cart body 1 collides with an object, the connecting rod 4 at the lower end of the shopping basket 6 retracts toward the inside of the slide slot 3 during the force application, and the shopping cart body 1 is buffered under the action of the first buffer spring 5. The user pulls the handle 9 to drive the limiting rod 8 to disengage from the inside of the limiting slot 7, so that the connecting rod 4 is released and can be out of the range of the slide slot 3 to disassemble the shopping basket 6. When the user needs to install the shopping basket 6, the user pulls the handle 9 to move it outward, and at the same time the reset spring 10 accumulates force, and after the connecting rod 4 at the bottom of the shopping basket 6 is aligned with the position of the slide slot 3 and inserted into a certain position, the handle 9 is released, and the limiting rod 8 is automatically driven to insert into the inside of the limiting slot 7 under the action of the reset spring 10 to fix the shopping basket 6. The user rotates the knob 16 with The movable threaded rod 13 moves downward, so that the distance between the threaded rod 13 and the fixed plate 17 becomes smaller. After moving down a certain distance, the lower end of the top plate 12 at the bottom end of the threaded rod 13 abuts against the upper end of the mounting plate 11, and the upper end of the rear baffle 15 abuts against the lower end of the mounting plate 11, fixing the rear baffle 15 to the rear end of the shopping cart body 1 to prevent the rear object from colliding with the rear end of the shopping cart body 1 and causing damage. The user drives the threaded rod 13 to move downward by rotating the knob 16, so that the distance between the threaded rod 13 and the fixed plate 17 becomes smaller. After moving down a certain distance, the lower end of the anti-skid pad 18 at the bottom end of the top plate 12 abuts against the upper end of the mounting plate 11, making the fixation of the rear baffle 15 to the shopping cart body 1 more stable. When the rear vehicle collides with the front vehicle, the second buffer spring 19 at the front end of the anti-collision plate 20 buffers the impact force.
