[0031] See also Figure 1-Figure 7 The present invention provides a multifunctional sitting shopping cart, comprising: A shopping cart body 1, on which a seat switching mechanism is provided; The seat switching mechanism includes a moving plate 3, a connecting plate 4, a backing plate 5, a seat plate 6, a shopping basket 7, a positioning block 8, a vertical plate 9, a T-block 10, a control head 16 and a driving shaft 17; A storage groove is provided on the side of the shopping cart body 1, the top of the movable plate 3 is fixedly connected to the connecting plate 4, the back plate 5 is fixedly connected to the connecting plate 4 and the seat plate 6, the top of the positioning block 8 is fixedly connected to the shopping basket 7, a positioning hole is provided on the top of the shopping cart body 1, the positioning block 8 is clamped with the positioning hole, the vertical plate 9 is fixedly connected with the connecting plate 4 and the T-block 10, a T-hole 11 is provided on the side of the positioning block 8, the T-block 10 is clamped with the T-hole 11, the end of the control head 16 is fixedly connected to the driving shaft 17, the driving shaft 17 is rotatably installed on the shopping cart body 1, an external thread is provided on the outer side of the driving shaft 17, and a screw hole threadedly connected to the external thread is provided on the side of the movable plate 3.

[0032] By means of the seat switching mechanism, the control head 16 is rotated, and the control head 16 drives the driving shaft 17 to rotate. The driving shaft 17 can drive the moving plate 3 to move through the cooperation of the external thread and the screw hole, and the moving plate 3 drives the connecting plate 4 to move, and the connecting plate 4 drives the back plate 5 to move, and the back plate 5 drives the seat plate 6 to move, so that the seat plate 6 is moved out of the storage slot. Then the elderly can sit on the seat plate 6 to rest, or push the shopping cart body 1 to go shopping. The switching is convenient, which is particularly suitable for the elderly with inconvenient legs and feet. In addition, when the shopping basket 7 needs to be cleaned later, the control head 16 is continued to be started, so that the connecting plate 4 continues to move to the left, the connecting plate 4 drives the vertical plate 9 to move, and the vertical plate 9 drives the T-block 10 to move, so that the T-block 10 is separated from the T-hole 11. At this time, the shopping basket 7 can be pulled upwards and the shopping basket 7 can be removed for cleaning, which is more convenient to use.

[0033] Specifically, the seat switching mechanism also includes a support plate 12, a driven shaft 13, a bevel gear 14, a bevel gear 2 15, a steel shell 18 and a steel ball 19. The support plate 12 is fixedly mounted on the side wall of the storage groove, the driven shaft 13 is rotatably mounted on the support plate 12, the bevel gear 14 is fixedly sleeved on the outer side of the driving shaft 17, the bevel gear 2 15 is fixedly mounted on the bottom end of the driven shaft 13, the bevel gear 14 is meshed with the bevel gear 2 15, the steel shell 18 is fixedly mounted on the top end of the driven shaft 13, and the steel ball 19 is located inside the steel shell 18.

[0034] Through the above structure, when the driving shaft 17 rotates, it will drive the bevel gear 14 to rotate, the bevel gear 14 will drive the bevel gear 2 15 to rotate, the bevel gear 2 15 will drive the driven shaft 13 to rotate, and the driven shaft 13 will drive the steel shell 18 to rotate, so that the steel ball 19 collides with the steel shell 18 in the steel shell 18, and then makes a sound. In this way, it can play a good warning role and prevent collision in the process of moving out the seat.

[0035] Specifically, the shopping basket 7 is in contact with the shopping cart body 1. Four moving wheels 1 are installed at the bottom of the shopping cart body 1, and two moving wheels 2 are installed at the bottom of the backboard 5. It should be noted that two of the four moving wheels 1 can be electric wheels that can automatically drive the shopping cart body 1, and the moving wheels 2 are wheels with brake structures.

[0036] Specifically, a crutch placement seat 20 is fixedly provided on the side of the back plate 5, and two placement boxes 21 are fixedly provided on the top of the connecting plate 4. It should be noted that the crutch placement seat 20 is used to place crutches, and the placement boxes 21 can be used to place items such as flashlights, umbrellas, battery modules and charging stands.

[0037] Specifically, a connecting hole is opened on the side of the shopping cart body 1. It should be noted that the sound generated by the collision between the steel ball 19 and the steel shell 18 can be derived from the connecting hole.

[0038] Specifically, a moving groove is opened on the inner wall of the bottom of the storage groove, and the moving plate 3 is slidably installed in the moving groove. It should be noted that it is convenient for the moving plate 3 to move horizontally.

[0039] Specifically, a control mechanism 2 is installed on the side of the shopping cart body 1. The control mechanism 2 includes a speaker, a sound pickup module, a wireless communication module and a main control board. The speaker, the sound pickup module and the wireless communication module are connected to the main control board.

[0040] Through the above structure, the wireless communication module is connected to the mobile phone terminal for communication, which is convenient for dialogue, weather query, one-key emergency alarm and talking with family members, etc., and has good functionality.

[0041] The above is a detailed introduction to the multifunctional sit-down shopping cart provided by the present invention. The principles and implementation methods of the present invention are described in detail using specific embodiments. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention.
