[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0016] In the embodiments of the present application, Figure 1 As shown, the luggage cart includes a body 10, front wheels 20, rear wheels 30, a steering mechanism 40 and a power supply device 50. The body 10 defines a storage space for storing luggage. The front wheels 20 and the rear wheels 30 are both mounted on the bottom surface of the body 10. The steering mechanism 40 is connected to the front wheels 20 to control the steering of the front wheels 20, thereby realizing the function of the luggage cart turning left and right. The power supply device 50 is arranged on the body 10, and is used to provide electrical energy to the body 10, so that the body 10 can convert the electrical energy of the power supply device 50 into mechanical energy of the body 10, thereby driving the body 10 to move forward, solving the problem that the luggage cart needs to be pushed or pulled by hand during movement, and reducing the burden on the user's hands.

[0017] There is one front wheel 20 and two rear wheels 30. The front wheel 20 and the two rear wheels 30 are arranged in a triangle relationship. The front wheel 20 can use a hub motor. The power supply device 50 is connected to the hub motor to drive the hub motor to rotate, and the rear wheel 30 is driven by the front wheel 20 to rotate. Through the above arrangement, not only the stability of the luggage cart when carrying people is increased, but also the steering mechanism 40 is convenient for operating the front wheel 20 to steer, thereby simplifying the operation of the luggage cart.

[0018] In addition, both rear wheels 30 can be set as directional wheels, which are directional wheels that can only run in the direction of the luggage cart's advance or retreat, but not in a direction perpendicular to the direction of the luggage cart's advance or retreat, effectively increasing the stability of the luggage cart when carrying people.

[0019] Optionally, in one embodiment, see Figure 1-Figure 3 The steering mechanism 40 includes a steering wheel 41, a telescopic tube 42, a stand tube 43 and a front fork 44. The front fork 44 is connected to the front wheel 20. One end of the stand tube 43 is connected to the front fork 44, and the other end of the stand tube 43 is connected to the telescopic tube 42. The steering wheel 41 is connected to one end of the telescopic tube 42 away from the stand tube 43. In this embodiment, due to the telescopic setting of the telescopic tube 42, the control height of the steering wheel 41 can be adjusted, which can adapt to the use of children of different heights, making it easier and more comfortable for children to operate the luggage cart.

[0020] For further information, see Figure 3 The telescopic tube 42 includes a first tube section 421 and a second tube section 422 located inside the first tube section 421. The first tube section 421 and the second tube section 422 are slidably connected. The first tube section 421 is connected to the vertical tube 43, and the second tube section 422 is connected to the steering wheel 41. By sliding the second tube section 422 relative to the first tube section 421, the steering wheel 41 is driven to slide in the vertical direction, so that the height of the steering wheel 41 can be increased or decreased, making it convenient for children of different sizes to ride the luggage cart.

[0021] For further information, see Figure 3 and Figure 4 A plurality of insertion holes 4211 are arranged at intervals on the first tube section 421, a button 411 is arranged on the steering wheel 41, a transmission rod 4221 is arranged in the second tube section 422, the transmission rod 4221 is connected to the button 411 through a spring 423, an insertion rod 4222 is arranged at the end of the second tube section 422 away from the button 411, the middle part of the insertion rod 4222 is rotatably connected to the second tube section 422 through a rotating shaft, one end of the insertion rod 4222 is connected to the transmission rod 4221, and the other end of the insertion rod 4222 is inserted into the insertion hole 4211.

[0022] When the height of the steering wheel 41 needs to be adjusted, the button 411 is pressed, and the button 411 drives the transmission rod 4221 to move downward, and the transmission rod 4221 drives the insertion rod 4222 to rotate, so that the insertion rod 4222 is in contact with the socket 4211, and then the second tube section 422 is slid. When the force applied to the button 411 is cancelled, the spring 423 is reset to drive the transmission rod 4221 to move upward, and the insertion rod 4222 rotates in the opposite direction and is inserted into the corresponding socket 4211, thereby realizing the height adjustment of the steering wheel 41. During the entire steering wheel 41 adjustment process, it is only necessary to press the button 411 to complete the operation, which saves time and effort and greatly improves the user experience.

[0023] Optionally, in one embodiment, a control module is provided inside the luggage cart, and the control module is connected to the front wheels 20 to change the rotation speed of the front wheels 20 to realize the acceleration and deceleration functions of the luggage cart. At the same time, the control module can also control the front wheels 20 to rotate forward or backward to realize the forward or backward function of the luggage cart.

[0024] An acceleration button 412 and a deceleration button 413 are provided on the steering wheel 41. The acceleration button 412 and the deceleration button 413 are connected to the control module through a wiring harness. Specifically, the control module includes a microcontroller. When the acceleration button 412 is pressed, the microcontroller can receive the control command transmitted by the acceleration button 412 and increase the rotation speed of the front wheels 20 to realize the acceleration function of the luggage cart; when the deceleration button 413 is pressed, the microcontroller can receive the control command transmitted by the deceleration button 413 and reduce the rotation speed of the front wheels 20 to realize the deceleration function of the luggage cart.

[0025] Optionally, in one embodiment, both sides of the vehicle body 10 are provided with footrests 11, and the user can place his feet on the corresponding footrests 11 when riding, thereby improving the user's riding experience. Specifically, both sides of the vehicle body 10 are provided with grooves 12, and the footrests 11 are rotatably connected to the vehicle body 10 so that the footrests 11 can rotate relative to the grooves 12. When riding the luggage cart, the footrests 11 rotate to the outside of the vehicle body 10 for the user to place his feet, and when storing, the footrests 11 can rotate into the grooves 12 and be flush with the outer surface of the vehicle body 10.

[0026] For example, the vehicle body 10 can be designed to be in the shape of cattle, sheep, antelopes, etc. In this embodiment, Figure 1 and Figure 2 As shown, the body 10 is mainly composed of the cow body, and the head of the body 10 is in the shape of a cow head that is integrally formed with the cow body and connected to each other by an arc surface, so that the overall lines of the body 10 are more concise and soft, with high simulation, beautiful appearance, novel structure, and greatly improved interest.

[0027] In some embodiments, the power supply device 50 is detachably connected to the vehicle body 10, so that the power supply device 50 not only has the function of supplying power to the luggage cart, but also has the function of a power bank. When the luggage cart needs to work, the power supply device 50 is assembled on the vehicle body 10 so that the vehicle body 10 can obtain electrical energy, and there is no need to equip the luggage cart with a dedicated power supply, thereby increasing the portability of the luggage cart. At the same time, the power supply device 50 can also serve as a power source for a variety of electronic devices, such as mobile phones, Bluetooth headsets, and computers, and can serve as a power bank when the electronic devices are out of power, thereby diversifying the application scenarios of the power supply device 50.
