Technical Field

[0001] This invention relates to the field of luggage technology, specifically to an electric luggage with omnidirectional wheels. Background Technology

[0002] Suitcases are an indispensable item for people when traveling, used to store clothing, daily necessities and other luggage. At present, most suitcases on the market are equipped with swivel wheels, making it easy for users to push or pull them forward, which improves their flexibility compared to traditional fixed-wheel suitcases.

[0003] The number and distribution ratio of wheels in existing electric luggage boxes are unreasonable, which cannot guarantee stability when turning, and they are prone to tilting and jamming during towing.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed an electric suitcase with omnidirectional wheels. Summary of the Invention

[0005] The purpose of this invention is to provide an electric suitcase with omnidirectional wheels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric suitcase with universal wheels, comprising a suitcase body, a battery compartment, and a drive motor. The suitcase body has a lid at its opening. The battery compartment is fixedly installed on one side wall of the suitcase body, and a battery is embedded inside the battery compartment. A charging interface is provided on the outer side wall of the battery compartment. A combination lock and a handle are respectively provided on the top surface of the suitcase body. A steering mounting groove is provided in the middle of the left side of the top of the suitcase body. A power button is installed on the upper left side of the suitcase body. A steering handle is provided in the steering mounting groove, and a control button is installed on the top operating end of the steering handle. An inner rod is fixedly connected to the bottom of the steering handle, and an outer rod is slidably fitted onto the outside of the inner rod. The drive motor is fixedly installed at the lower end of the outer rod, and a steering wheel is provided below the drive motor. A steering wheel is rotatably installed in the middle of the left side of the bottom of the suitcase body. The output shaft of the drive motor is connected to the steering wheel via a gearbox. Auxiliary wheels are symmetrically rotatably installed on the front and rear sides of the steering wheel. A follower wheel is rotatably installed on the right side of the bottom of the suitcase body.

[0007] Furthermore, foot pedals are fixed to the lower front and lower back of the enclosure, and anti-collision strips are provided on the outer surface of the foot pedals. The anti-collision strips are made of rubber or elastic plastic and serve to cushion, reduce noise, and prevent scratches.

[0008] Furthermore, the charging interface is electrically connected to the battery, and the control button is electrically connected to the drive motor and the battery.

[0009] Furthermore, the auxiliary wheel is a small-sized omnidirectional wheel, and the follower wheel is a large-sized one-way wheel.

[0010] Furthermore, the ratio of the number of steering wheels, auxiliary wheels, and follower wheels is 1:2:2, and the steering wheels, auxiliary wheels, and follower wheels are all on the same horizontal plane. The auxiliary wheels are omnidirectional wheels that can turn freely 360°.

[0011] Furthermore, the inner rod and the outer rod constitute a telescopic steering rod structure, and a limiting component is provided between the inner rod and the outer rod to restrict the telescopic position of the inner rod relative to the outer rod. The limiting component is a ball-type snap-fit, threaded locking, or button-type locking structure, realizing multi-level height adjustment.

[0012] Furthermore, wires pass through the inner and outer rods, with one end of the wires connected to the power button and the other end connected to the drive motor and the battery.

[0013] The gearbox is a reduction and torque-increasing gearbox, which increases the torque of the drive wheel to ensure smooth starting and strong climbing ability.

[0014] The battery is a lithium battery, and the battery compartment has a waterproof, shockproof, and flame-retardant structure. The charging interface is equipped with a waterproof plug.

[0015] Both the control button and the power button are waterproof. The control button is used to start and stop the drive motor and switch modes, while the power button is used to turn the main power on and off.

The present invention has a steering wheel, an auxiliary wheel, and a follower wheel distributed in a ratio of 1:2:2, and all three are on the same horizontal plane. The auxiliary wheel is a small universal wheel that can turn freely in 360°, and the follower wheel is a large one-way wheel. The three work together to effectively solve the problems of unstable steering, easy tilting and jamming during dragging of existing electric suitcases. Flexible dragging can be achieved without additional adjustment of the suitcase posture, improving the convenience of use.

[0017] 2. The inner and outer rods of this invention operate on the same telescopic principle as existing levers. After pressing the control button, pulling the steering handle allows the inner rod to slide along the inside of the outer rod. With the help of the limiting component, the inner rod can be fixed in the desired telescopic position, thereby precisely adjusting the operating height of the steering handle to suit the operating needs of users of different body sizes. The operation is convenient and the structure is easy to understand. At the same time, the wires inside the inner and outer rods connect the power button, drive motor, and battery. The battery compartment is used to fix the battery, and the charging interface can replenish power in a timely manner, ensuring stable power supply and control signals, and further improving the reliability of the device.

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, an electric suitcase with omnidirectional wheels includes a suitcase body 1, a battery compartment 5, and a drive motor 14. The drive motor 14 is fixedly installed at the lower end of the outer rod 13, and a steering wheel 15 is provided below the drive motor 14. The inner rod 12 and the outer rod 13 form a telescopic steering rod structure. A limiting member is provided between the inner rod 12 and the outer rod 13 to limit the telescopic position of the inner rod 12 relative to the outer rod 13. A wire runs through the inner rod 12 and the outer rod 13. One end of the wire is connected to the power button 19, and the other end is connected to the drive motor 14 and the battery 6. The steering wheel is located at the middle of the left side of the bottom of the suitcase body 1. The steering wheel 15 is mounted on the housing 1. The output shaft of the drive motor 14 is connected to the steering wheel 15 via a gearbox. Auxiliary wheels 16 are symmetrically mounted on the front and rear sides of the steering wheel 15. Follower wheels 17 are rotatably mounted on the bottom right side of the housing 1. The auxiliary wheels 16 are small universal wheels, and the follower wheels 17 are large one-way wheels. The ratio of the number of steering wheels 15, auxiliary wheels 16 and follower wheels 17 is 1:2:2. The steering wheels 15, auxiliary wheels 16 and follower wheels 17 are all on the same horizontal plane. The auxiliary wheels 16 are universal wheels that can turn freely in 360°.

[0022] The specific operation is as follows: the steering wheel 15, the auxiliary wheel 16, and the follower wheel 17 are distributed in a ratio of 1:2:2, and the three are on the same horizontal plane. The auxiliary wheel 16 is a small universal wheel that can turn freely in 360°, and the follower wheel 17 is a large one-way wheel. The three work together to effectively solve the problems of unstable steering, easy tilting and jamming during dragging of existing electric luggage boxes. Flexible dragging can be achieved without additional adjustment of the posture of the box body 1, improving the convenience of use.

[0023] like Figures 1 to 3 As shown, a lid 2 is provided at the opening of the box body 1. Steps 3 are fixed on the lower front and lower back of the box body 1, and anti-collision strips 4 are provided on the outer surface of the steps 3. The battery compartment 5 is fixedly installed on one side wall of the box body 1, and a battery 6 is embedded inside the battery compartment 5. A charging interface 7 is provided on the outer side wall of the battery compartment 5. A combination lock 8 and a handle 9 are respectively provided on the top surface of the box body 1. A steering mounting groove 18 is opened in the middle of the left side of the top of the box body 1. A power button 19 is installed on the upper left side of the box body 1. A steering handle 10 is provided in the steering mounting groove 18, and a control button 11 is installed on the top operating end of the steering handle 10. The charging interface 7 is electrically connected to the battery 6. The power button 19 is electrically connected to the drive motor 14 and the battery 6. An inner rod 12 is fixedly connected to the bottom of the steering handle 10, and an outer rod 13 is slidably sleeved on the outside of the inner rod 12.

[0024] The specific operation is as follows: the inner rod 12 and the outer rod 13 have the same telescopic principle as the existing pull rod. After the control button 11 is pressed, the steering handle 10 can be pulled to slide the inner rod 12 along the inside of the outer rod 13. With the help of the limiting component, the inner rod 12 can be fixed in the required telescopic position, thereby accurately adjusting the operating height of the steering handle 10 to suit the operating needs of users of different body sizes. The operation is convenient and the structure is easy to understand. At the same time, the wires inside the inner rod 12 and the outer rod 13 are connected to the power button 19, the drive motor 14 and the battery 6. The battery compartment 5 is fixedly installed with the battery 6, and the charging interface 7 can replenish power in time, ensuring stable power supply and control signal, and further improving the reliability of the device.

[0025] In summary, when using this electric suitcase with omnidirectional wheels, the power supply system is activated first, and the battery 6 provides power to the entire device. The charging interface 7 can replenish the battery 6 at any time to ensure the continuous and stable operation of the device. At the same time, the control button 11 controls the up and down movement of the inner rod 12, and the limiting component fixes the extension and retraction positions of the inner rod 12 and the outer rod 13, thereby adjusting the steering handle 10 to a suitable operating height for the user. The wires inside the inner rod 12 and the outer rod 13 are connected to the power button 19, the drive motor 14 and the battery 6 to ensure stable control signals and power transmission.

[0026] When entering riding mode, the user starts the drive motor 14 via the power button 19. The drive motor 14 drives the steering wheel 15 to rotate via the gearbox, providing forward propulsion for the luggage. The user can turn the steering handle 10 to drive the steering wheel 15 to deflect. The auxiliary wheel 16 deflects synchronously with the steering wheel 15, and the follower wheel 17 adapts to the steering in the riding direction to achieve flexible steering control of the luggage. The pedal 3 is for the user to step on, and the anti-collision strip 4 provides cushioning protection.

[0027] When entering non-riding towing mode, the user turns off the power button 19, putting the drive motor 14 into standby mode. At this time, the auxiliary wheel 16, as a omnidirectional wheel, is in a free-turning state, and the follower wheel 17, as a one-way wheel, can adaptively roll along the towing direction. By optimizing the number and distribution ratio of wheels, the steering wheel 15, auxiliary wheel 16, and follower wheel 17 are distributed in a 1:2:2 ratio and are on the same horizontal plane. Combined with the flexible steering characteristics of the auxiliary wheel 16, the tilting and jamming phenomena that are prone to occur during the towing of existing electric suitcases are effectively solved. The user can achieve flexible towing without additional adjustment of the posture of the suitcase 1.

[0028] Throughout the operation, the small-sized omnidirectional auxiliary wheels 16 and the large-sized unidirectional follower wheels 17 work together, and the reasonable distribution of each wheel and their arrangement on the same horizontal plane further ensure the stability of the box body 1. At the same time, the combination lock 8 ensures the safety of luggage, the handle 9 facilitates carrying, the battery compartment 5 is used to install and fix the battery 6, and the box cover 2 seals the box body 1. All the structures work together to ensure the normal operation of the device.
