Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of luggage, in particular to an electric luggage. BACKGROUND

[0002] With the continuous development of living standards and society, people's phenomenon of going out for travel and business trips is increasingly common. In order to make the journey more convenient, people often choose to carry luggage to place articles. However, when carrying a large amount of luggage, or needing to walk a long distance, or going out with children, the traditional pull rod luggage is time-consuming and laborious when being pushed and pulled, which brings many inconveniences to people's normal walking and increases the burden of travel. In order to solve this problem, the market currently has electric luggage that can be ridden with power assistance function. Users can ride on the box body and operate the control device to ride the electric luggage, which can save user's physical strength.

[0003] A smart electric luggage is disclosed in Chinese Patent No. CN214854882U, which includes a box body, a control element, and front and rear wheels and a footrest structure. The top of the box body can be ridden by a person. A hollow sleeve is arranged at the front end inside the box body. The sleeve penetrates the box body and has open ends at both ends. A pull rod is installed in the cavity of the sleeve. The pull rod can slide up and down relative to the sleeve. The bottom of the pull rod extends out of the lower open end of the sleeve and is connected to the front wheel through an axle support. The pull rod can rotate horizontally inside the sleeve to control the steering of the front wheel. The top of the pull rod extends out of the upper open end of the sleeve and is connected to a handlebar. A locking mechanism is arranged at the upper open end of the sleeve to lock and fix the position of the pull rod relative to the box body.

[0004] The above-mentioned luggage, when in use, due to its three-wheeled structure, during turning, etc., the three wheels are too close to the center of gravity of the entire luggage, which can easily cause the luggage to tip over during turning, thereby affecting the safe use of the luggage.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned problems. CONTENT OF THE UTILITY MODEL

[0006] In order to make the luggage more stable during movement, the present application provides an electric luggage.

[0007] The electric luggage provided by the present application adopts the following technical solution:

[0008] An electric luggage includes a box body, two driven wheels arranged at the lower end of the box body, a driving assembly for driving the box body to move, and a supporting assembly for keeping the box body balanced.

[0009] The driving assembly comprises a steering rod rotatably connected to the box body, a driving wheel rotatably connected below the steering rod, a motor for driving the driving wheel to rotate, a controller for controlling whether the driving wheel rotates or not, and a storage battery for power supply, the storage battery is arranged in the box body and electrically connected with the motor and the controller, and the motor is fixed to the steering rod.

[0010] The supporting assembly is arranged in two groups and arranged on both sides of the box body in the moving direction, and comprises a pedal arranged at the lower end of the box body and an auxiliary wheel rotatably connected below the pedal, the lower end of the auxiliary wheel can be at the same horizontal plane as the lower end of the driven wheel and the lower end of the driving wheel.

[0011] By arranging the auxiliary wheel on the pedal, the auxiliary wheel supports both sides of the luggage case when the luggage case moves, so that the luggage case has more support positions and can keep stable when moving and turning.

[0012] Optionally, a mounting seat is arranged below the box body, the pedal is rotatably connected to the mounting seat, and the rotating shaft of the pedal is horizontally arranged and perpendicular to the rotating axis of the driven wheel.

[0013] By adopting the above technical scheme, the angle of the pedal downward rotation can be adjusted according to the requirement when the luggage case moves, so that the auxiliary wheel can always be in abutment with the ground, thereby keeping the box body in a stable moving state.

[0014] Optionally, the pedal is provided with an anti-disengagement part at the end away from the box body, and the end of the anti-disengagement part away from the pedal is inclined toward the direction away from the auxiliary wheel.

[0015] By adopting the above technical scheme, after the pedal is downwardly rotated under the downward pressure, the foot can abut against the anti-disengagement part, so that the foot is not easy to disengage from the pedal directly, thereby keeping the pedal in a stable downward state and the auxiliary wheel in abutment with the ground, and the auxiliary wheel can keep the box body balanced when moving.

[0016] Optionally, the mounting seat is rotatably connected below the box body, and the rotating axis of the mounting seat is vertically arranged.

[0017] By adopting the above technical scheme, when the pedal and the auxiliary wheel are not needed, the pedal can be rotated toward the box body along the rotating axis of the mounting seat, so that the pedal is moved below the box body and does not directly protrude from the surface of the box body, and the pedal is not easy to be hooked by the sundries on the road when the luggage case is dragged, so that the dragging of the luggage case is not easily affected.

[0018] Optionally, the pedal is provided with a reset elastic member for driving the pedal to rotate upward.

[0019] By adopting the above technical solution, the pedal can be kept in a certain position when it is not subjected to downward pressure, so that the auxiliary wheel can be kept in a state of moving away from the ground, so that the auxiliary wheel is not in contact with the ground. Therefore, when the pedal is moved towards the bottom of the suitcase, it is not easily obstructed by the auxiliary wheel. Furthermore, when the suitcase is manually dragged, the pedal can also be kept in contact with the suitcase without shaking, so that the suitcase is not easily affected by the pedal when being dragged.

[0020] Optional: The pedal is provided with anti-slip texture.

[0021] By adopting the above technical solution, even after the sole of the shoe is wetted with liquid, the anti-slip texture can still maintain a stable connection between the sole and the pedal, allowing the foot to stand stably on the pedal and making the normal use of the pedal less affected.

[0022] Optionally, the lower end of the housing is provided with a stop block that limits the horizontal rotation angle of the mounting base, and the stop block can abut against the side of the mounting base away from the drive wheel.

[0023] By adopting the above technical solution, as the suitcase moves forward, the pedal will be subject to the friction force applied by the ground and will tend to rotate towards the rear of the suitcase. The position of the pedal is limited by the stop block, so that the auxiliary wheel on the pedal can be stably kept in contact with the ground, thereby enabling the suitcase to move stably.

[0024] Optionally: the anti-detachment part can abut against the side wall of the box, and an elastic pad is provided on the side wall where the anti-detachment part abuts against the box.

[0025] By adopting the above technical solution, after the pedal rotates towards the box body, the anti-slip part will not directly abut against the outer wall of the box body. Instead, the elastic element will directly abut against the outer wall of the box body, and the elastic pad can deform. This reduces the wear between the elastic pad and the outer wall of the box body when they come into contact, making it less likely for wear marks to appear on the outer wall of the box body.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By installing auxiliary wheels on the pedals, the auxiliary wheels support the sides of the suitcase when it moves, giving the suitcase more support points and making it more stable when moving and turning.

[0028] 2. After the pedal is subjected to downward pressure and rotates downward, the foot can abut against the anti-slip part, making it difficult for the foot to directly slip off the pedal. This allows the pedal to maintain a stable downward position, keeping the auxiliary wheel in contact with the ground, and enabling the auxiliary wheel to maintain the balance of the box during movement.

[0029] 3. The pedal can be kept in a certain position when no downward pressure is applied, so that the auxiliary wheel can be kept in a state of moving away from the ground, and the auxiliary wheel is out of contact with the ground, so that the pedal is not easily hindered by the auxiliary wheel when moving towards the lower part of the box, and the pedal can be kept in contact with the box without shaking when the luggage is manually dragged, so that the pedal does not easily affect the luggage when it is being dragged.

DETAILED DESCRIPTION

[0034] The present application will be further described in detail below in combination with the drawings.

[0035] The electric luggage disclosed in the present application is shown in the figure, which comprises a box 1, a driving assembly 2, a supporting assembly 3 and a pedal 31. Figure 1 and Figure 2 ​As shown, the luggage case 1 comprises a box body 1, two driven wheels 11 arranged below the box body 1, a driving assembly 2 for driving the box body 1 to move, and a supporting assembly 3 for keeping the box body 1 balanced. The two driven wheels 11 are arranged at the lower end surface of the box body 1. The driving assembly 2 comprises a steering rod 21 vertically penetrating the box body 1, a driving wheel 22 rotatably connected to the lower end of the steering rod 21, a motor 23 for driving the driving wheel 22 to rotate, a controller for controlling whether the driving wheel 22 rotates or not, and a storage battery for power supply. The steering rod 21 vertically penetrates the box body 1 and is rotatably connected to the box body 1. The steering rod 21 is arranged at a position away from the driven wheels 11. The rotation axis of the driving wheel 22 is parallel to the rotation axis of the driven wheels 11. The lower end of the driving wheel 22 is at the same horizontal plane as the lower end of the driven wheels 11. The motor 23 is a servo motor 23 in this embodiment. The motor 23 is arranged at the lower end of the steering rod 21 and above the driving wheel 22. The output shaft of the motor 23 is connected to the driving wheel 22 through a gear box, so as to drive the driving wheel 22 to rotate. The storage battery is arranged in the inner cavity of the box body 1 and close to the steering rod 21. A partition is arranged in the inner cavity of the box body 1, so as to separate the space for storing clothes in the box body 1 from the space for storing the storage battery. The storage battery is electrically connected to the controller and the motor 23. The upper end of the steering rod 21 is provided with a handle 24. A button 25 for pressing is arranged on the handle 24. The button 25 is electrically connected to the controller. When it is needed to control the luggage case to move, the button 25 is pressed. The button 25 feeds the forward signal to the controller. The controller controls the motor 23 to work, so as to drive the driving wheel 22 to rotate, and the luggage case moves forward. When it is not needed to control the luggage case to move, the button 25 is not pressed, so as to make the motor 23 not work, and the luggage case stops.

[0036] The supporting assembly 3 is arranged in two groups. The two groups of supporting assemblies 3 are arranged below the box body 1 and at both sides of the box body 1 in the moving direction of the box body 1. The supporting assembly 3 comprises a pedal 31 arranged below the box body 1 and an auxiliary wheel 32 rotatably connected to the lower end of the pedal 31. Two mounting seats 13 are rotatably connected to the lower end of the box body 1. The rotation axis of the mounting seat 13 is vertically arranged. The pedal 31 is rotatably connected to one mounting seat 13. The rotation axis of the pedal 31 is horizontally arranged. When the length direction of the pedal 31 is parallel to the rotation axis of the driven wheels 11, the rotation axis of the pedal 31 is perpendicular to the rotation axis of the driven wheels 11. The rotation axis of the auxiliary wheel 32 is perpendicular to the moving direction of the box body 1. The lower end of the auxiliary wheel 32 is inclined to the direction away from the box body 1. When the user sits on the box body 1 and steps on the pedal 31, the end of the pedal 31 away from the box body 1 rotates downward, and the auxiliary wheel 32 moves downward to the same horizontal plane as the lower end of the driven wheels 11. That is, the lower end of the auxiliary wheel 32 can abut on the ground, so as to support the box body 1, and the box body 1 can keep stable when moving.

[0037] As Figure 3 shown in the drawings, when the user steps on the pedal 31, the end of the pedal 31 away from the box 1 will tilt downward, which will cause the user's foot to move downward when stepping on the pedal 31, and thus the user cannot stably step on the pedal 31. Therefore, the end of the pedal 31 away from the box 1 is further provided with an anti-falling part 33, the end of the anti-falling part 33 away from the pedal 31 tilts upward, and the end of the anti-falling part 33 away from the pedal 31 is further provided with an extension part 34. The anti-falling part and the extension part hinder the movement of the user's foot relative to the pedal 31, so that the user's foot cannot directly fall off the pedal 31, and the user's foot can stably step on the pedal 31, so that the auxiliary wheel 32 can abut against the ground, and thus the luggage case can be kept stable when in use.

[0038] When it rains, the bottom of the shoe will be wet, and when the shoe steps on the pedal 31, the shoe and the pedal 31 will slip. Therefore, the pedal 31 is further provided with a plurality of anti-skid lines 311, which are arranged along the length direction of the pedal 31. The anti-skid lines 311 increase the friction between the pedal 31 and the shoe, so as to reduce the occurrence of slipping when the shoe is wet.

[0039] When the pedal 31 is not needed, it needs to be rotated toward the box 1. If the auxiliary wheel 32 keeps abutting against the ground, it will hinder the movement of the pedal 31 toward the box 1. Therefore, the pedal 31 is further provided with a reset elastic member 35 for driving it to rotate upward. In this embodiment, the reset elastic member 35 is a spring, which is arranged between the mounting seat 13 and the pedal 31, so as to push the pedal 31 to rotate upward. When the pedal 31 is not subjected to downward pressure, the pedal 31 can rotate upward, so that the auxiliary wheel 32 does not contact the ground, and the rotation of the pedal 31 toward the box 1 is not easily affected.

[0040] When the auxiliary wheel 32 contacts the ground, the pedal 31 will be subjected to a force toward the rear of the movement direction of the pedal 31 toward the box 1, so that the pedal 31 rotates toward the rear of the box 1, which affects the support of the auxiliary wheel 32 to the box 1. Therefore, the lower end of the box 1 is further provided with a stopper 12 for limiting the horizontal rotation angle of the mounting seat 13. The stopper 12 is arranged on the side of the mounting seat 13 away from the driving wheel 22, so that after the mounting seat 13 rotates, the stopper 12 can abut against the mounting seat 13, so that the mounting seat 13 is kept at a certain position. When the pedal 31 is subjected to the resistance applied by the ground, the position of the pedal 31 relative to the box 1 can still be kept stable, so that the auxiliary wheel 32 on the pedal 31 can stably support the box 1.

[0041] Since the anti-coming-off portion 33 will collide with the outer wall of the box body 1 when the pedal 31 is rotated towards the box body 1, the outer wall of the box body 1 is prone to be worn. Therefore, an elastic pad 36 is arranged on the side wall of the box body 1 which is in contact with the anti-coming-off portion 33. The elastic pad 36 is made of rubber in this embodiment. After the anti-coming-off portion 33 is rotated towards the box body 1, the elastic pad 36 on the anti-coming-off portion 33 can abut against the outer wall of the box body 1, thereby reducing the wear of the outer wall of the box body 1 caused by the direct contact between the anti-coming-off portion 33 and the outer wall of the box body 1.

[0042] The implementation principle of this embodiment is as follows: in use, the box body 1 is rotated towards the ground with the side close to the driving wheel 22, so that the driven wheel 11 and the driving wheel 22 abut against the ground. Then the anti-coming-off portion 33 is pinched to move the pedal 31 away from the box body 1, so that the mounting seat 13 is rotated to abut against the stopper 12. Then the user sits on the box body 1 and puts his feet on the pedal 31, so that the pedal 31 is rotated downwards until the auxiliary wheel 32 abuts against the ground. The user holds the handle 24 and presses the button 25, so that the motor 23 is powered on to drive the driving wheel 22 to rotate, and the driving wheel 22 drives the box body 1 to move.

[0043] The embodiments of the specific embodiments are the preferred embodiments of the present application, but do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
