Description

Technical Field

[0001] This utility model relates to the field of shopping cart technology, specifically a novel electrically driven passenger-carrying shopping cart. Background Technology

[0002] A typical example of a shopping cart in the prior art, such as Publication No. CN222360966U, provides a shopping cart that includes a structure with wheels to carry bags. The structure is formed of a hollow plastic rod with two different dimensions in cross-section: a larger dimension and a smaller dimension. The structure includes crossbars arranged parallel to the smaller dimension. The cart's structure is very lightweight yet very strong.

[0003] For example, a typical example of a shopping cart in the prior art is disclosed in CN210116522U, which describes a shopping cart including a frame. Both sides of the bottom front end of the frame are provided with casters. Each caster includes a caster bracket and a first wheel. The first wheel is rotatably engaged below the caster bracket. A rotating mechanism is provided between the bottom of the frame and the caster bracket to allow the caster bracket to rotate circumferentially. This utility model provides a shopping cart that is simple to operate and convenient to use.

[0004] In summary, current shopping carts typically carry passengers while they sit inside. However, because the cart frame is grille-like, passengers lean directly against it, causing back discomfort and making it inconvenient to fold and store. When designed with an external seat, the cart becomes unstable after the seat is folded up, making it prone to tipping over. To address these issues, existing equipment needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of electric-driven passenger shopping cart to solve the problems mentioned in the background art. In general, the existing shopping carts carry people by having people sitting inside the cart. Because the shopping cart frame is grid-shaped, the person being carried leans directly against the shopping cart frame, which causes back discomfort and is inconvenient to fold and store. When designed as an external seat, the center of gravity of the entire cart is unstable after the seat is folded up, and the cart is prone to tipping over.

[0006] This utility model provides a novel electrically driven passenger shopping cart, including a support base, a drive front wheel at the bottom of the support base, a shopping cart box fixed to the top of the support base, a first bracket fixed to one side of the shopping cart box, and a control panel fixed to the top of the first bracket.

[0007] A second bracket is rotatably connected to one side of the first bracket. A seat is fixed to the top of the second bracket. A backrest is rotatably connected to the top of the seat. Two outer tubes are rotatably connected to one side of the second bracket. An inner tube is slidably connected to the inner side of the outer tubes. A rotating shaft is rotatably connected to the bottom of the two inner tubes. Rear wheels are symmetrically fixed at both ends of the rotating shaft.

[0008] Preferably, brake discs are symmetrically fixed on both sides of the support base, and foot pads are symmetrically arranged on both sides of the support base.

[0009] With the above technical solution, when braking is not required, the foot can be placed on the footrest; when braking is required, the foot is pressed on the footrest to activate the brake disc, thereby controlling the brake.

[0010] Preferably, a battery pack is fixed inside the bottom of the support base, and the battery pack is electrically connected to the drive front wheel, brake disc, foot pad and control panel.

[0011] Through the above technical solution, the battery pack can power the entire device, thereby ensuring the normal use of the device.

[0012] Preferably, the second bracket is fixed to the first bracket by the first fastener, and the outer tube is fixed to the second bracket by the second fastener.

[0013] Through the above technical solution, the first fastener can be used to fix the second bracket, and the second fastener is used to fix the outer tube.

[0014] Preferably, a layer of soft mesh is installed on the backrest.

[0015] The above technical solution makes the backrest more comfortable to use.

[0016] Preferably, the inner tube and the outer tube form a telescopic structure, and the inner tube is fixed to the outer tube by a pin.

[0017] The above technical solution allows the inner tube to be pulled out after the vehicle is folded up, and the rear wheels to touch the ground, thus preventing the entire device from becoming unstable.

[0018] The technical effects that can be achieved by the technical means of this utility model are as follows:

[0019] 1. This new type of electric-driven passenger shopping cart can carry people by using the coordinated use of the front drive wheel, brake disc, foot pad, seat and backrest. The front drive wheel can drive the device to move, and people can sit on the seat. Before using the seat, the backrest needs to be rotated open. When people sit on the seat, they can lean on the backrest. Stepping on the foot pad can activate the brake disc to control the brake of the front drive wheel.

[0020] 2. This new type of electric-driven passenger shopping cart achieves telescopic stability through the coordinated use of a second bracket, a first fastener, a backrest, an outer tube, a second fastener, an inner tube, a pin, and rear wheels. After closing the backrest and loosening the first and second fasteners, the second bracket can be folded and stored. After fixing the second bracket and the outer tube, the pin can be removed and the inner tube extended, allowing the rear wheels to touch the ground. This prevents the rear wheels from not touching the ground after the cart is folded, which would cause instability. The inner and outer tubes are telescopic, thus making up for the distance between the rear wheels. Finally, the inner tube can be fixed with the pin. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] A preferred embodiment of the novel electric-driven passenger shopping cart provided by this utility model is as follows: Figures 1 to 3 As shown, it includes a support base 1, a drive front wheel 2 is provided at the bottom of the support base 1, a shopping cart box 5 is fixed at the top of the support base 1, a first bracket 6 is fixed on one side of the shopping cart box 5, and a control panel 7 is fixed at the top of the first bracket 6.

[0032] A second bracket 9 is rotatably connected to one side of the first bracket 6. A seat 11 is fixed to the top of the second bracket 9. A backrest 12 is rotatably connected to the top of the seat 11. Two outer tubes 13 are rotatably connected to one side of the second bracket 9. An inner tube 15 is slidably connected to the inner side of the outer tube 13. A rotating shaft 17 is rotatably connected to the bottom of the two inner tubes 15. Rear wheels 18 are symmetrically fixed at both ends of the rotating shaft 17.

[0033] In this embodiment, brake discs 3 are symmetrically fixed on both sides of the support base 1, and foot pads 4 are symmetrically arranged on both sides of the support base 1. When a person sits on the seat 11, he / she can place his / her feet on the foot pads 4. The foot pads 4 support the feet. When braking is required, the foot is stepped on the foot pads 4 to activate the brake discs 3. The brake discs 3 clamp the drive front wheel 2 to stop the drive front wheel 2 from rotating, thereby achieving the braking effect.

[0034] Furthermore, a battery pack 8 is fixed inside the bottom of the support base 1, and the battery pack 8 is electrically connected to the drive front wheel 2, brake disc 3, foot pad 4 and control panel 7. The battery pack 8 can convert DC power into AC power for the entire device under the action of the inverter, thereby ensuring the normal operation of the device.

[0035] Example 2

[0036] Based on Embodiment 1, a preferred embodiment of the novel electrically driven passenger-carrying shopping cart provided by this utility model is as follows: Figures 4 to 7 As shown,

[0037] In this embodiment, the second bracket 9 is fixed to the first bracket 6 by the first fastener 10, and the outer tube 13 is fixed to the second bracket 9 by the second fastener 14. The second bracket 9 and the first bracket 6 are rotatable, and the outer tube 13 and the second bracket 9 are rotatable. After the second bracket 9 is unfolded or folded, the second bracket 9 can be fixed by the first fastener 10, and the outer tube 13 can be fixed by the second fastener 14.

[0038] Furthermore, a soft mesh is installed on the backrest 12. The backrest 12 can be rotated open before using the seat 11. When people sit on the seat 11, they can lean on the backrest 12. The mesh design of the backrest 12 makes it more comfortable to use.

[0039] Furthermore, the inner tube 15 and the outer tube 13 form a telescopic structure, and the inner tube 15 is fixed to the outer tube 13 by the pin 16. When the seat 11 is in use, the rear wheel 18 contacts the ground and the rear wheel 18 rolls to assist the device in moving. If the seat 11 is not in use, the second bracket 9 is folded up and then the inner tube 15 needs to be extended and the rear wheel 18 needs to touch the ground to avoid the rear wheel 18 not being able to touch the ground after the whole vehicle is folded, which would cause the center of gravity to be unstable. The inner tube 15 and the outer tube 13 are telescopic, thereby making up for the distance of the rear wheel 18.

[0040] In use, the entire device is controlled via the control panel 7. The front drive wheel 2, equipped with a drum motor and powered by a battery, propels the device forward, causing the rear wheel 18 to roll. After rotating and opening the backrest 12, a person can sit on the seat 11 and lean against the backrest 12, with hands resting on the first support 6 and feet on the footrest 4. A soft mesh is installed on the backrest 12 to enhance comfort. The entire device can be controlled via the control panel 7. Items can be placed in the shopping cart 5. When braking is needed, the footrest 4 is pressed to activate the brake. The brake disc 3 clamps the front drive wheel 2, stopping its rotation and thus achieving a braking effect. After rotating and closing the backrest 12, loosening the first fastener 10 and the second fastener 14 allows the second bracket 9 to be rotated and folded up. After securing the second bracket 9 and the outer tube 13 with the first fastener 10 and the second fastener 14, remove the pin 16, pull out the inner tube 15, and then secure the inner tube 15 with the pin 16 after the rear wheel 18 touches the ground. Each inner tube 15 has two insertion holes. After extending or retracting the inner tube 15, the pin 16 can be inserted into the corresponding insertion hole, thus completing the entire operation.

[0041] In summary, this new type of electric-driven passenger shopping cart achieves the goal of carrying people and maintaining stability through extension, thus meeting people's usage needs.
