Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to a logistics trolley structure adapted to a balance scooter. Background Technology

[0002] Electric self-balancing scooters are a new type of transportation. These two-wheeled scooters are supported by two wheels, powered by a battery, driven by a brushless motor, and controlled by a microcontroller. An attitude sensor collects angular velocity and angle signals to coordinate and control the scooter's balance. With years of development, the technology of self-balancing scooters has become increasingly mature, and the failure rate has decreased. However, they are still not suitable for personal use in complex environments such as roads. Nevertheless, they can be used in large indoor spaces such as shopping malls, factories, and logistics companies to increase work efficiency.

[0003] There are some transportation tools on the market that use self-balancing scooters as a power source, such as the self-balancing scooter-driven cargo cart disclosed in Chinese Utility Model Patent Application 202322798613.1. This cart includes a self-balancing scooter body and a cart. The self-balancing scooter body has a frame, and the frame has a clamping device detachably connected to the cart. The self-balancing scooter body acts as the power source, driving the frame and cart. The frame includes a mounting base, on which a connecting seat is movably mounted, and the clamping device is mounted on the connecting seat. When the cart is in use, the mounting base can move relative to the connecting seat, allowing the self-balancing scooter body to move relative to the clamping device, facilitating flexible control of the self-balancing scooter body. The cart includes a support plate with at least three support wheels, at least one of which is a swivel wheel. When the cart turns, the swivel wheel rotates relative to the support plate, allowing the cart to turn flexibly with the self-balancing scooter body.

[0004] While the above structure facilitates flexible control of the warehouse balance scooter and the trolley, the connecting seat is connected to the trolley via a clamping device. When going downhill or when there are large obstacles between the balance scooter and the trolley, there is a risk that the trolley and the clamping device may separate, posing a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a logistics cart structure adapted to balance scooters in order to solve the problem of unstable connection and safety hazards caused by the existing clamping device connecting balance scooters and carts.

[0006] To achieve the above objectives, this utility model provides a logistics cart structure adapted to a self-balancing scooter, comprising: a self-balancing scooter body, a cart, and a connecting frame. The cart includes a support plate, casters, and a handle. The handle is disposed on the support plate, and the support plate is provided with a positioning hole. A connecting screw is disposed in the positioning hole. One end of the connecting screw is connected to the caster, and the other end of the connecting screw is connected to the connecting frame. The connecting frame is disposed on the self-balancing scooter body.

[0007] As a further description of the above technical solution:

[0008] An elastic gasket is provided inside the connecting frame, and the elastic gasket is located between the connecting frame and the support plate.

[0009] As a further description of the above technical solution:

[0010] The elastic gasket is adhered to the connecting frame.

[0011] As a further description of the above technical solution:

[0012] The connecting frame includes a frame and a connecting seat. The frame is mounted on the balance scooter body, and the connecting seat is hinged to the connecting seat. The connecting seat has a through hole, and the connecting screw passes through the through hole.

[0013] As a further description of the above technical solution:

[0014] The through hole is a waist-shaped hole.

[0015] As a further description of the above technical solution:

[0016] A locking nut is provided on the connecting screw, and the locking nut is located above the connecting seat.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: A positioning hole is opened on the support plate, and a connecting screw is inserted into the positioning hole. The bottom of the connecting screw is connected to the caster, and the top of the connecting screw is connected to the connecting frame. In this way, the caster and the connecting frame can be connected to the trolley through a single connecting screw, which reduces the number of holes drilled on the trolley and the number of connecting screw accessories used, thus reducing manufacturing costs. At the same time, the connecting frame fixed on the balance trolley is secured by the connecting screw and the locking nut, making the connection more robust and stable, thus preventing the balance trolley from separating from the trolley during use and ensuring good safety.
