[0031] Specifically, an anti-skid pad 13 is disposed on the upper end surface of the brake pad 10 , and a group of anti-skid protrusions are fixedly connected to the surface of the anti-skid pad 13 .

[0032] In this embodiment, the anti-skid pad 13 has a good anti-skid function, which can increase the friction between the child's feet and the brake pad 10 to avoid slipping. The anti-skid protrusion can further increase the friction.

[0033] Specifically, a charging port 15 is provided on the side wall of the frame 1 , and the charging port 15 is electrically connected to the battery 39 .

[0034] In this embodiment, the charging port 15 is convenient for charging the battery 39, which is convenient for continuous use, has better flexibility, and can be used continuously.

[0035] Specifically, both ends of the handle bar 7 are sleeved with rubber sleeves 20 , and the outer surface of the rubber sleeve 20 is provided with anti-slip patterns.

[0036] In this embodiment, the rubber sleeve 20 can increase the friction between the child and the handle bar 7, making it easier for the child to hold the handle bar 7 tightly and making it easier for the child to use the handle bar.

[0037] Specifically, two groups of limiting plates 29 are fixedly connected to the handle bar 7 , each group of limiting plates 29 has two limiting plates 29 , and the spacing between adjacent limiting plates 29 is the same as the width of the first clamping block 21 .

[0038] In this embodiment, the limiting piece 29 can limit the first clamping block 21 and the second clamping block 22 to prevent the hook 25 from moving, so that the object can be stably hung.

[0039] Specifically, both side walls of the frame 1 are provided with openings, and the openings are in a rectangular shape.

[0040] In this embodiment, the opening facilitates the rotation of the rotating rod 36, so that the position of the mounting block 16 can be adjusted, and automatic induction balance can be achieved.

[0041] Specifically, the wheel hub motor 8 , the micro cylinder 17 , the pressure sensor 26 , the micro motor 33 and the wireless signal transceiver module 41 are all electrically connected to the controller 40 .

[0042] In this embodiment, the controller 40 is electrically connected to the hub motor 8, the micro cylinder 17, the pressure sensor 26, the micro motor 33 and the wireless signal transceiver module 41, which facilitates the control of the skateboard shopping cart through a mobile phone and improves the intelligence of the skateboard shopping cart.

[0043] Specifically, both side walls of the frame 1 are fixedly connected with protection frames 14 .

[0044] In this embodiment, the protection frame 14 can protect the mounting block 16 to prevent the mounting block 16 from being stepped on, thereby increasing the service life of the skateboard shopping cart.

[0045] The working principle and use process of the present invention are as follows: when the elderly hang items on the hook 25, the pressure sensor 26 detects the pressure and transmits the signal to the controller 40. The controller 40 drives the micro motor 33 to work. The micro motor 33 drives the threaded rod 32 to rotate. The rotation of the threaded rod 32 causes the moving block 34 to move. The movement of the moving block 34 changes the position of the mounting block 16. When the micro motor 33 moves to the target position, the micro cylinder 17 drives the connecting plate 18 to move downward, so that the universal wheel 19 contacts the ground, thereby being able to automatically sense the balance. The user can send a signal to the wireless signal transceiver module 41 through the mobile phone, and then the wireless signal transceiver module 41 transmits the signal to the controller 40, which is convenient for control through the mobile phone and has a better degree of intelligence.
