[0049] Example 2

[0050] like Figures 1 to 15The electric suitcase shown in the figure, including the box body 1, the box body 1 is provided through left and right, and the left and right sides are connected with the left frame 2 and the right frame 3, the front side of the box body 1 is provided with a password lock, that is, when the password lock is located between the box body 1 and the left frame 2, the user can put clothes by opening the left frame 2, and when the password lock is located between the box body 1 and the right frame 3, the user can put clothes by opening the right frame 3. In addition to the basic storage space in the box body 1, the left frame 2 is extended to the left to provide a first expansion area 201, which is actually a square frame made of hard material. The storage space on the right side of the first expansion area 201 is connected with the box body 1, realizing the expansion of the storage space. Furthermore, a second expansion area 301 is provided on the right side of the right frame 3. The second expansion area 301 has three units and is installed at the "┌" three-point position. The second expansion area 301 is actually a soft and stretchable square frame. One side edge of the square frame is provided with a connecting belt, and the remaining edges are locked by means of a zipper. Unlike the first expansion area 201, the storage space of the second expansion area 301 is not connected with the box body 1, that is, the three second expansion areas 301 each have a separate storage space. The user can put shoes, wet clothes, computers and other items that are not convenient to put together with other items to avoid damage, dirt and other situations caused by mutual influence.

[0051] The bottom of the first expansion area 201 is recessed forward to provide a first recycling groove 30, and the right frame 3 is provided with a second recycling groove 31 below the second expansion area 301. The highest points of the first recycling groove 30 and the second recycling groove 31 are lower than the first expansion area 201 and the second expansion area 301.

[0053] Embodiment 3

[0054] As Figures 1 to 15 The utility model provides an electric suitcase, including box body 1, left frame 2 and right frame 3, constitute the whole storage space of the utility model, the top of box body 1 is equipped with handle, namely when the user is not horizontal movement, such as getting on and off the car, the scene that needs to carry the whole suitcase to move, the user can hold the whole suitcase up by handle with one hand, the other hand holds the bottom of suitcase and assists power, and then the whole suitcase is lifted.

[0055] The top of the rear side of box body 1 is recessed to the downward inclination and is provided with a pulling slot 4, and a pulling handle 5 is slidably arranged in the pulling slot 4, and specifically, the pulling handle 5 is in the shape of two rods that are slidably pulled upward from the inside of the box body 1, and the top of the rods is connected by a pulling block, so that the user can pull the pulling block to move the two rods upward together, and the top of the pulling block has the same angle as the suitcase, so that the pulling handle 5 does not protrude from the edge of the suitcase in the retracted state, and the contact and collision with the human body or other objects can be avoided. In short, the pulling handle 5 can satisfy the adjustment of the height and fix the height after adjustment, so as to adapt to different use requirements and scenes of the user.

[0056] When the pulling handle 5 is retracted, it means that the suitcase is in a non-manual driving scene, and the pulling handle 5 with a proper length can be used by the user to horizontally push the suitcase to move, and the longer pulling handle 5 can be used by the user to move the suitcase quickly and easily by relying on the wheels on one side after tilting the suitcase. In actual application, the degree of height adjustment of the pulling handle 5 also needs to be specifically referred to according to the height of the user.

[0057] The pulling slot 4 is downwardly extended and provided with an insertion slot 34, and the width of the insertion slot 34 is smaller than that of the pulling slot 4, so that when a battery 36 is slidably arranged in the pulling slot 4 and the battery 36 supplies power to the driving elements in the electric suitcase, including but not limited to a motor that drives the wheels to automatically rotate, a USB charging interface that provides power to external electrical appliances (mobile phones and tablets), a GPS that can find the position of the suitcase at any time and realize positioning tracking, etc. The external battery 36 can also make the replacement of the power supply of the electric suitcase simple and fast. When replacing and installing, the user inserts the contact end of the battery 36 downward into the insertion slot 34 until the interface (not shown in the figure) at the bottom of the insertion slot 34 is inserted, so as to complete the electrical connection and power supply to the internal electrical appliances. In order to avoid the battery 36 from falling out and affecting use, the insertion slot 34 is provided with a limiting block 35 on the left and right inner walls, so as to realize multi-directional limiting of the battery 36, and when the pulling handle 5 is in the retracted state, the bottom of the pulling handle 5 can also be used to further limit the battery 36, so as to avoid the battery 36 from falling out.

[0058] Embodiment 4

[0059] As Figures 1 to 15 shown in one of the electric suitcase, the user can sit on the suitcase to drive it, to achieve easy travel in stable terrain. When driving, the box 1 gives the hip support, and the foot pedal 32 supports the leg, to maintain further stability, the first slot is opened in the front side of the box 1 (i.e. the side opposite to the pull handle 5), the first slot is downwardly installed with the slide cylinder 9, the slide cylinder 9 is slidably provided with the telescopic rod 10, the telescopic rod 10 is normally retracted into the slide cylinder 9, which reduces the center of gravity of the front side of the suitcase, to avoid the user to move the whole suitcase by the pull handle 5, the front side of the center of gravity is too large to cause the user to use more force to push, which can not realize the easy use of the product.

[0060] Most importantly, when the user needs to sit on the suitcase to move, the telescopic rod 10 can be pushed up to an appropriate height, which is slightly lower than the height of the user's shoulder, and the height adjustment can be operated by the transverse operating rod 11 provided at the top of the telescopic rod 10, the top of the transverse operating rod 11 is provided with an adjusting key 12, the adjusting key 12 is provided by pressing, when pressing, it means that the telescopic rod 10 is released, at this time, the user pushes the transverse operating rod 11 to drive the telescopic rod 10 to stretch or retract, and the adjustment is completed, the adjusting key 12 is no longer pressed to restore the clamping of the telescopic rod 10, the height of the telescopic rod 10 is fixed after adjustment, and the user's hands are held.

[0061] In addition to the adjusting key 12, the left and right sides of the transverse operating rod 11 are also provided with a reversing key 13, which is used to adjust the direction of the suitcase. The reversing key 13 is divided into a front key and a rear key, as the name implies, the front key means that the suitcase moves forward, and the rear key means that the suitcase moves backward. The bottom of the shell 161 is rotatably provided with a main wheel through the hinge slot 6, the hinge slot 6 is connected with the connecting shaft 7 upward through the shell 161, and the connecting shaft 7 is connected with the bottom end of the telescopic rod 10, that is, the user can drive the telescopic rod 10 to rotate by pushing the left and right sides of the transverse operating rod 11, the telescopic rod 10 rotates to drive the connecting shaft 7, the hinge slot 6 and the main wheel to swing, which realizes the left and right reversing of the suitcase, and realizes the omnidirectional control of the suitcase by the front key and the rear key.

[0062] Considering the different shoulder widths of different groups of people, such as women and men, there is a significant difference in shoulder width between them. When the length of the horizontal operating lever 11 is fixed, the user can only support the outermost end of the horizontal operating lever 11 at most. For some people with wider shoulders, the width of the horizontal operating lever 11 is shorter than the width of their shoulders, forcing their shoulders to hunch over. This not only leads to a poor user experience, but may also cause the hands to lose balance with the suitcase, resulting in the person losing balance and falling. Therefore, an adjustable extension rod 39 is provided to accommodate the optimal shoulder width of different drivers and maintain balance. The horizontal operating lever 11 has locking rods 37 extending outwards on both sides, with multiple locking holes 38 on the rear. The extension rod 39 slides on the locking rods 37 for direct contact and support with the human hand. The extension rod 39 is hollow and closed on the outside. A locking bead 41 is connected inside the extension rod 39 via a second elastic element 40. The locking bead 41 engages with the locking holes 38. When the locking bead 41 is within the locking hole 38, the extension rod 39 is fixed and limited to the locking rod 37, requiring adjustment of its length. During adjustment, rotate the extension rod 39 up and down until the locking ball 41 disengages from the locking hole 38 and rests between the outer wall of the locking rod 37 and the inner wall of the extension rod 39. The second elastic element 40 is compressed, and the extension rod 39 is no longer fixed. Push it to move left and right to the appropriate position. Then rotate the extension rod 39 again until the locking ball 41 moves back to the locking hole 38. At this time, the second elastic element 40 resets and drives the locking ball 41 to move backward, restoring the fixed limit on the extension rod 39. This completes the length adjustment of the extension rod 39, which is adapted to the optimal driving shoulder width of different people and prevents them from falling over after losing their balance.

[0063] Example 5

[0064] like Figures 1 to 15 The electric luggage shown further enhances its anti-tipping performance during driving by incorporating an expandable rear wheel assembly. This assembly consists of a first auxiliary wheel 17 and a second auxiliary wheel 18, both located at the rear bottom of the luggage. It is known that an object is more stable and less prone to tipping over when subjected to external forces if its center of gravity is low and its base area is large. When an adult is placed on top of the electric luggage, the adult's weight lowers the center of gravity, but this still doesn't guarantee it won't tip over during driving. In this embodiment, before driving, the first auxiliary wheel 17 and the second auxiliary wheel 18 are moved outwards, increasing the distance between them and thus increasing the base area of ​​the luggage. Simultaneously, the distance between the first auxiliary wheel 17, the second auxiliary wheel 18, and the luggage is shortened, tilting the rear end of the luggage backwards. This lowers the actual center of gravity of the luggage, thereby increasing stability and preventing tipping.

[0065] The bottom rear side of the box body 1 has a recessed adjustment groove 14 to isolate the rear wheel assembly adjustment and prevent it from affecting the items stored inside the suitcase. A first drive component 15 is located at the top of the adjustment groove 14. The first drive component 15 is specifically a cylinder, and the bottom of the cylinder's extension rod 10 is connected to an adjustment component 16. It is easy to see that the rear wheel assembly is located within the adjustment component 16. When the user does not need to drive the suitcase, they can adjust the suitcase to "non-passenger mode" on a mobile app. After receiving the signal, the control module will activate the first drive component 15, causing the adjustment component 16 to move up and down, thus adjusting the rear wheel assembly. The lowest point is adjusted to be on the same horizontal line as the lowest point of the main wheel to facilitate normal use of the suitcase by the user. When the user needs to drive the suitcase, the suitcase can be adjusted to "passenger mode". After receiving the signal, the control module will drive the cylinder to start, which will move the adjustment component 16 upward, thereby shortening the distance between the adjustment component 16 and the rear wheel assembly and the suitcase. This will cause the rear side of the suitcase, that is, the side where the buttocks are in contact with the suitcase, to tilt downward. After the user sits down, he / she can use his / her own weight to tilt the entire center of gravity of the suitcase downward, preventing the suitcase from tipping over.

[0066] Example 6

[0067] like Figures 1 to 15 An electric suitcase is shown, including an adjustment component 16. The adjustment component 16 includes a housing 161. The top and rear edges of the housing 161 are similar to the outer edge of the suitcase. An operation panel 162 is provided on the rear side of the inner wall of the housing 161. The operation panel 162 extends forward and protrudes from the housing 161. The front edge of the operation panel 162 is the same as the inner wall of the adjustment groove 14. Therefore, when the telescopic rod 10 of the first drive component 15 is shortened, the adjustment component 16 can be driven to retract completely into the adjustment groove 14, thereby indirectly lowering the center of gravity. The top of the control panel 162 is symmetrically provided with guide rails 163. Sliding members 164 are slidably provided on the guide rails 163. The outer side of the sliding member 164 is extended outward to form a blocking tendency. The inner side of the sliding member 164 is provided with a secondary rail 165. Each secondary rail 165 is connected to a stop block 167 via a slider 166. The stop block 167 is L-shaped. The outer side of the stop block 167 is provided with a support member 168. The support member 168 is also L-shaped. The part of the support member 168 located below the control panel 162 can be interlocked. That is, in the normal state, the support member 168 will be exactly against the left and right sides of the control panel 162, and drive the support member 168 below it to interlock with each other, so that the two support members 168 form a U-shape. Through the counteracting of the two, the first secondary wheel 17 and the second secondary wheel 18 in the adjustment member 16 are fixed, so that they are kept at the same horizontal line as the lowest point of the main wheel, which is conducive to the normal movement of the user in the "non-human-loaded mode".

[0068] The bottom of the shell 161 is provided with a mounting bracket 23 made of hard titanium material. The bottom of the mounting bracket 23 is provided with a fixed sliding sleeve 24. The fixed sliding sleeve 24 is hollow and symmetrically provided with a first shaft 25 and a second shaft 26. The outer sides of the first shaft 25 and the second shaft 26 are rotatably provided with a first secondary wheel 17 and a second secondary wheel 18 through a snap ring 27. The bottom of the support member 168 is provided with a clamping sleeve 28. The clamping sleeve 28 is clamped between the first secondary wheel 17, the second secondary wheel 18 and the snap ring 27. When the support member 168 is moved outward, the clamping sleeve 28 is pressed against the snap ring 27 to move the first shaft 25 and the second shaft 26 outward, thereby moving the first secondary wheel 17 and the second secondary wheel 18 outward, expanding the distance between the first secondary wheel 17 and the second secondary wheel 18 and increasing stability.

[0069] After the first shaft 25 and the second shaft 26 are slid outward from the fixed sliding sleeve 24, the middle part is hollow, which cannot guarantee the stability of the first secondary wheel 17 and the second secondary wheel 18. Therefore, an auxiliary support member 21 is provided to indirectly reinforce and stabilize the first shaft 25 and the second shaft 26 by pressing against the moving support member 168. The bottom of the operation plate 162 is symmetrically provided with auxiliary guide rails 19. The auxiliary guide rails 19 are slidably provided with the auxiliary support member 21 through auxiliary sliding blocks 20. The auxiliary support member 21 is in a wave shape and can fit the missing parts of the two support members 168. When the auxiliary guide rails 19 move backward into the support members 168, they can collide with the two support members 168, making the support members 168 still in a regular square shape and indirectly fixing the first shaft 25 and the second shaft 26.

[0070] The top of the operation plate 162 is provided with a second driving member 29, which is a micro air cylinder. The push rod of the second driving member 29 is connected with the inner side abutting block 167 and serves as a power source for adjusting the first secondary wheel 17 and the second secondary wheel 18. The auxiliary guide rails 19 are connected with the swing rods 22 between the adjacent support members 168 to synchronize the movement of the support members 168.

[0071] This can be understood as follows: When the user is in "non-passenger mode," the cylinder's telescopic rod 10 is in the extended state, causing the adjusting component 16 and its bottom first auxiliary wheel 17 and second auxiliary wheel 18 to remain horizontal, that is, to be on the same horizontal line as the lowest point of the main wheel, thus keeping the entire suitcase in a balanced state, facilitating various movements or handling of the suitcase by the user. When the user needs to drive the suitcase, the user does not need to sit on the suitcase. Activating "passenger mode," the control panel receives a signal and first drives the second drive component 29 to operate. The push rod of the second drive component 29 extends, causing the sliding component 164 to move outward first. When the sliding component 164 moves to its limit, the push rod continues to extend, causing the support component 168 to move backward. As the support member 168 moves backward, the auxiliary support member 21 moves to the right via the swing rod 22. As the auxiliary support frame moves to the right, the front support member 168 moves outward synchronously via the swing rod 22. After the auxiliary support member 21 moves to a position higher than the support member 168, the push rod is activated to shorten, moving the support member 168 inward while the auxiliary support member 21 moves backward to reset via the swing rod 22 until the three are engaged. At this point, the support member 168 is in an outward moving state relative to its initial state. Then, the first shaft 25 and the second shaft 26 move outward via the retainer 28, ultimately achieving the effect of moving the first auxiliary wheel 17 and the second auxiliary wheel 18 outward respectively, thus widening the distance between them.

[0072] Thus, when the adjusting component 16 moves upward, it causes the entire suitcase to tilt backward. Considering that when an adult is carried in the electric suitcase, the center of gravity of the suitcase will be lower than in a horizontal state after being subjected to pressure, and the distance between the first auxiliary wheel 17 and the second auxiliary wheel 18 increases, together with the main wheel, the bottom area of ​​the suitcase will increase using the formula: area = 1 / 2 (bottom * height). This makes the electric suitcase more stable during driving and less likely to tip over.

[0073] Example 7

[0074] like Figures 1 to 15 The electric suitcase shown also includes a controller, which is installed on a mobile terminal. The controller is connected to the adjustment key 12, the reversing key 13, the battery 36, the first drive component 15, and the second drive component 29. The adjustment component 16 is used to adjust the movement and stop of the electric suitcase, the reversing key 13 is used to adjust the direction of travel of the electric suitcase, and the battery 36 is used to power the various components. The controller can be installed on the mobile terminal (mobile app) to facilitate users to issue commands. The controller is connected to the various components via Bluetooth to receive commands issued by the user or adjustment data made by the user manually to the adjustment key 12 and the reversing key 13, and to perform corresponding operations on the various drive components.
