[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0051] Reference Figures 1 to 4 The first aspect of this utility model provides an electric suitcase 1, comprising: a suitcase body 11, including two oppositely arranged side plates 111, a sliding cavity 19 formed between the two side plates 111, and a protrusion 112 provided on the side plates 111; a sliding member 12, which is slidably connected to the sliding cavity 19, and has a sliding groove 121 on the side of the sliding member 12 facing the side plate 111, the sliding groove 121 being slidably connected to the protrusion 112; and an electric push rod 16, one end of which is fixed to the suitcase body 11, and the electric push rod 16 is electrically... The other end of the push rod 16 is connected to the slider 12 to drive the slider 12 to reciprocate; the front handle bar 14 is connected to the case 11 via the slider 12, and the front handle bar 14 is used to change the direction of movement of the electric suitcase 1; the battery is disposed on the front handle bar 14 or the case 11; the drive wheel assembly 13 is connected to the bottom of the front handle bar 14 and the case 11, the drive wheel assembly 13 is electrically connected to the battery, and the drive wheel assembly 13 is used to drive the electric suitcase 1 to move.

[0052] Since the front handlebar 14 is usually close to the electric suitcase 1 in the initial state, before use, the user can control the slider 12 to slide out of the suitcase 11, so that the front handlebar 14 connected to the slider 12 also moves forward, leaving enough space so that the user can easily hold the front handlebar 14 to control the direction of movement of the electric suitcase 1 while riding on the electric suitcase 1; then the user can sit on the electric suitcase 1 and start the drive wheel set 13 to drive the electric suitcase 1 to move, thus easily completing the transportation of the electric suitcase 1.

[0053] The case 11, as the main structure of the electric suitcase 1, can accommodate items and the sliding component 12, and protect them from external impacts and pressure. A sliding cavity 19 is formed between the side panels 111 of the case 11, allowing the sliding component 12 to move back and forth within the cavity 19, thus achieving the function of storing and protecting the sliding component 12. Furthermore, the sliding cavity 19 ensures that when the sliding component 12 moves relative to the case 11, the entire sliding component 12 is supported and limited by the cavity 19, thereby improving the stability of the sliding component 12 during movement.

[0054] The protrusions 112 on the two opposing side plates 111 of the case 11 can cooperate with the sliding grooves 121 of the sliding member 12, providing guidance and limiting for the sliding member 12, so that the sliding member 12 can move stably relative to the case 11. The case 11 can be made of high-strength engineering plastics, such as polycarbonate, polyphenylene ether, polyimide, etc., which have low density and good flexibility, pressure resistance, wear resistance and corrosion resistance, and can meet various usage scenarios in daily travel. The shape of the case 11 can be selected according to design needs. For example, the case 11 can be set as a cuboid, and the case 11 can be divided into an upper shell and a lower shell that are hinged to each other along the middle position. By setting a zipper or buckle between the upper shell and the lower shell, it is convenient for users to open and close the electric suitcase 1 to store and retrieve items.

[0055] The drive wheel assembly 13 is used to drive the movement of the housing 11. Exemplarily, the drive wheel assembly 13 may include a hub motor and wheels. The wheels are disposed on the bottom surface of the housing 11, and the drive end of the hub motor is connected to the wheels to drive the wheels of the electric luggage 1 to rotate. The drive wheel assembly 13 can also be other common drive devices, and this embodiment of the invention does not limit this. A battery is electrically connected to the drive wheel assembly 13 to provide electrical power to the drive wheel assembly 13, enabling the drive wheel assembly 13 to operate normally.

[0056] The front handlebar 14 is a component for the user to control the direction of movement of the electric luggage compartment 1. The user can change the direction of movement of the electric luggage compartment 1 by gripping and controlling the rotation of the front handlebar 14. For example, the front handlebar 14 may include a grip, a connecting rod, and a roller connected in sequence from top to bottom. The orientation of the roller can be adjusted by twisting the grip, thereby adjusting the direction of movement of the electric luggage compartment 1. The front handlebar 14 may also be a vehicle front end composed of other structures, as long as it can realize the control of the direction of movement of the electric luggage compartment 1. This utility model embodiment does not limit this.

[0057] The sliding member 12 connects the front handlebar 14 and the housing 11. The sliding member 12 has a groove 121, which allows for slidable connection with a protrusion 112 on the side plate 111 of the housing 11, thus enabling relative movement between the front handlebar 14 and the housing 11. Understandably, the user can manually achieve relative movement between the sliding member 12 and the housing 11. For example, the user can apply external force to the front handlebar 14, causing the sliding member 12 to slide along the protrusion 112, thereby moving the front handlebar 14 to a suitable position. Alternatively, a drive mechanism, such as a cylinder or motor, can be added to control the relative movement between the sliding member 12 and the housing 11. The sliding member 12 can be made of materials such as metal, alloy, or engineering plastics, such as aluminum alloy, giving it good wear resistance and ensuring stable sliding contact with the protrusion 112 during long-term use, thereby improving its service life. The slider 12 can be elongated, and the depth of the groove 121 can be equal to or slightly greater than the thickness of the protrusion 112 on the side plate 111. This ensures that the protrusion 112 can slide freely within the groove 121 without creating an excessive gap between the protrusion 112 and the groove 121, thus improving the stability of the slider 12's movement. Multiple grooves 121 can be provided. For example, two grooves 121 can be provided on the slider 12, symmetrically arranged at both ends of the slider 12, thereby improving the stability of the slider 12 during movement.

[0058] This utility model provides a sliding groove 121 on the sliding member 12 and a corresponding protrusion 112 on the side plate 111 of the housing 11, so that the protrusion 112 and the sliding groove 121 cooperate with each other. When the sliding member 12 moves, the protrusion 112 can provide a certain support and limit the sliding member 12, thereby reducing the probability of the sliding member 12 shaking and improving the stability of the sliding member 12 when moving.

[0059] In one embodiment, the electric luggage case 1 further includes a limiting block 15, which is disposed in the slide groove 121 and can abut against the protrusion 112 to limit the movement of the sliding member 12.

[0060] The limiting block 15 is disposed within the slide groove 121, so that after the sliding member 12 slides to a certain position, the protrusion 112 abuts against the limiting block 15, thereby hindering further movement of the sliding member 12. The position of the limiting block 15 within the slide groove 121 can be set according to actual needs. For example, the limiting block 15 can be disposed at one end of the slide groove 121 closer to the inside of the case 11, so that when the sliding member 12 moves into the case 11 to a certain position, the limiting block 15 can restrict the sliding member 12 from moving further inward, preventing excessive movement of the sliding member 12 from colliding with the case 11 and causing damage to both the sliding member 12 and the case 11. Alternatively, the limiting block 15 can be disposed at one end of the slide groove 121 away from the inside of the case 11, so that when the sliding member 12 moves outward to a certain position, the limiting block 15 can restrict the sliding member 12 from moving further outward, thereby preventing excessive movement of the sliding member 12 from sliding out of the case 11, thus improving the safety of the electric suitcase 1. The limiting block 15 can be made of elastic materials such as rubber or polyurethane, so that the limiting block 15 has good elasticity and buffer performance. When the limiting block 15 abuts against the protrusion 112, the limiting block 15 can effectively absorb the impact force when the sliding member 12 moves, and reduce the noise and damage caused by the collision between the limiting block 15 and the protrusion 112.

[0061] There are multiple ways to connect the limiting block 15 and the slide groove 121. The limiting block 15 and the slide groove 121 can be detached by means of snap-fit, pin connection, magnetic connection, threaded connection, etc., which facilitates the replacement and cleaning of the limiting block 15. Alternatively, the limiting block 15 and the slide groove 121 can be non-detached by means of bonding, welding, etc., which makes the connection between the limiting block 15 and the slide groove 121 more stable.

[0062] In one embodiment, reference is made to Figure 4 Each slide 121 is provided with two limiting blocks 15, which are respectively located at both ends of the slide 121 along the moving direction of the box body 11.

[0063] By setting a limiting block 15 at both ends of the slide 121, the protrusion 112 can only move between the two limiting blocks 15. This not only makes it easier to control the moving distance of the sliding member 12, but also prevents the sliding member 12 from sliding out of the box body 11 or hitting the box body 11. The stability of the movement of the sliding member 12 improves the safety of the electric suitcase 1.

[0064] In one embodiment, reference is made to Figure 4 and Figure 5 The limiting block 15 is provided with a first connecting hole 151, and the slide groove 121 is provided with a second connecting hole 1211 corresponding to the first connecting hole 151. The first connecting hole 151 and the second connecting hole 1211 are bolted together.

[0065] The electric suitcase 1 is subjected to various external forces during use, such as bumps during transportation and collisions between the sliding component 12 and the limiting block 15 during user operation. Therefore, in this embodiment of the invention, the limiting block 15 is fixed in the slide groove 121 with bolts, which can improve the stability of the connection between the limiting block 15 and the slide groove 121 and reduce the probability of the limiting block 15 becoming loose or displaced. Furthermore, in cases where the limiting block 15 needs maintenance or replacement, the bolt connection also facilitates the removal of the limiting block 15, reducing the maintenance difficulty of the electric suitcase 1.

[0066] The number of first connecting holes 151 can be set as needed. For example, two first connecting holes 151 can be set, and two second connecting holes 1211 are set in the corresponding slide groove 121. The two first connecting holes 151 and the two second connecting holes 1211 are all connected by bolts, thereby further improving the stability of the connection between the limit block 15 and the slide groove 121.

[0067] In some embodiments, the number of second connecting holes 1211 can be set to multiple, so that the limiting block 15 can be connected to the second connecting hole 1211 at a suitable position as needed, making it convenient for the user to adjust the position of the limiting block 15 at any time, thereby meeting the needs of different situations.

[0068] In one embodiment, along the extension direction H1 of the groove, the ratio of the length of the protrusion 112 to the length of the groove 121 is less than or equal to 0.3; and / or,

[0069] Along the extension direction H1 of the slide, the length of the protrusion 112 is less than the length of the limiting block 15.

[0070] If the ratio of the length of the protrusion 112 to the length of the slide groove 121 is greater than 0.3, the length of the protrusion 112 is too large, occupying too much space in the slide groove 121, thus shortening the moving distance of the slider 12, and consequently reducing the user's seating and operating space. Therefore, in this embodiment of the invention, the ratio of the length of the protrusion 112 to the length of the slide groove 121 is set to be less than or equal to 0.3. For example, it can be 0.3, 0.25, 0.2, 0.15, 0.1, 0.08, 0.06, 0.04, 0.02, or 0.01, so that the volume of the protrusion 112 is small, providing sufficient distance for the slider 12 to move.

[0071] The limiting block 15 is longer than the protrusion 112, thereby ensuring that the limiting block 15 has sufficient strength. Since the limiting block 15 is usually made of a material with certain cushioning properties, such as rubber or silicone, the larger volume of the limiting block 15 can provide a larger buffer space, thereby reducing the damage caused by the impact between the limiting block 15 and the protrusion 112.

[0072] In one embodiment, reference is made to Figure 6The electric luggage case 1 also includes an electric push rod 16, which includes: a moving rod 161, which is fixedly connected to the sliding member 12; and a transmission rod 162, which is fixedly connected to the case body 11 and is transmittedly connected to the moving rod 161 to drive the moving rod 161 to reciprocate relative to the transmission rod 162.

[0073] The transmission rod 162 serves to support and drive the moving rod 161. For example, the transmission rod 162 can be a cylinder-like drive structure, fixed to the housing 11, with its drive end connected to the moving rod 161, thereby controlling the movement of the moving rod 161. Alternatively, the transmission rod 162 can be a lead screw, divided into two parts. The first part is fixedly connected to the housing 11, while the second part is rotatably connected to the first part. By fitting the moving rod 161 onto the second part and threadedly connecting it, the moving rod 161 can move back and forth when the second part rotates. The electric push rod 16 allows the movement of the sliding member 12 to be completed electrically, reducing the user's operational difficulty and improving the user experience.

[0074] In one embodiment, reference is made to Figure 6 The sliding member 12 has a through hole 122 extending along the extension direction H1 of the slide groove, and the electric push rod 16 passes through the through hole 122. By providing a through hole 122 in the sliding member 12, the electric push rod 16 can be stored in the through hole 122, thereby improving the space utilization of the electric luggage case 1 and saving more space to store the user's items.

[0075] In one embodiment, reference is made to Figure 4 and Figure 5 The sliding member 12 includes: a first structural member 123, which encloses a through hole 122; a second structural member 124, which has a top plate 1241, a bottom plate 1243, and two vertical plates 1242. The top plate 1241 and the bottom plate 1243 are disposed on both sides of the first structural member 123, and the vertical plates 1242 are connected between the top plate 1241 and the bottom plate 1243. The first structural member 123 is disposed between the two vertical plates 1242, and a sliding groove 121 is disposed on the vertical plate 1242; and a plurality of reinforcing plates 125, at least one reinforcing plate 125 being connected between the first structural member 123 and the top plate 1241, and at least one reinforcing plate 125 being connected between the first structural member 123 and the bottom plate 1243.

[0076] The sliding member 12 is composed of the first structural member 123, the second structural member 124, and the reinforcing plate 125 between them. That is, there is a cavity between the first structural member 123 and the second structural member 124, which reduces the mass of the sliding member 12, improves the portability of the electric luggage case 1, and makes the sliding member 12 easier to move. In addition, the setting of the reinforcing plate 125 also ensures that the sliding member 12 has sufficient structural strength and reduces the probability of the sliding member 12 breaking.

[0077] In one embodiment, four reinforcing plates 125 are provided, two of which are connected between the first structural member 123 and the top plate 1241, and two of which are connected between the first structural member 123 and the bottom plate 1243, thereby ensuring the stability of the connection between the first structural member 123 and the second structural member 124; and the four reinforcing plates 125 are symmetrically arranged, making the sliding member 12 more regular and easier to manufacture.

[0078] In one embodiment, reference is made to Figure 5 The base plate 1243 includes a first segment 1243a and a second segment 1243b arranged sequentially between two vertical plates 1242, with the first segment 1243a and the second segment 1243b spaced apart. One end of the first segment 1243a is connected to the first structural member 123 through a reinforcing plate 125, and the other end of the first segment 1243a is connected to a vertical plate 1242. One end of the second segment 1243b is connected to the first structural member 123 through another reinforcing plate 125, and the other end of the second segment 1243b is connected to another vertical plate 1242.

[0079] By dividing the base plate 1243 into a first segment 1243a and a second segment 1243b spaced apart, the contact area between the base plate 1243 and the housing 11 is reduced, and the friction between the sliding member 12 and the housing 11 is decreased, making the sliding member 12 easier to move. The distance between the first segment 1243a and the second segment 1243b can be set as needed, and this embodiment of the utility model does not impose any limitations on this.

[0080] In one embodiment, reference is made to Figure 4 and Figure 5 Along the width direction H2 of the housing, the vertical plate 1242 is recessed to form a groove 121, and the depth of the groove 121 is greater than or equal to the thickness of the limiting block 15. The depth of the groove 121 is greater than or equal to the thickness of the limiting block 15, so that the limiting block 15 is completely accommodated within the groove 121, thereby avoiding the limiting block 15 occupying extra space within the housing 11 and preventing the limiting block 15 from affecting the arrangement of other structures within the housing 11.

[0081] In one embodiment, reference is made to Figure 2The two side plates 111 include a first side plate 1111 and a second side plate 1112 that are spaced apart and opposite to each other. The housing 11 includes: a first shell 17, which includes a first locking plate 171, a second locking plate 172 and a first side plate 1111, with the first locking plate 171 and the second locking plate 172 spaced apart from the first side plate 1111; and a second shell 18, which includes a third locking plate 181, a fourth locking plate 182 and a second side plate 1112, with the third locking plate 181 and the fourth locking plate 182 spaced apart from the second side plate 1112; wherein the first locking plate 171 and the third locking plate 181 are connected, and the second locking plate 172 and the fourth locking plate 182 are connected, so that the first side plate 1111, the first locking plate 171, the second locking plate 172, the second side plate 1112, the third locking plate 181 and the fourth locking plate 182 form a sliding cavity 19.

[0082] The first card plate 171 and the third card plate 181 can be detachably connected by means of snap-fit, threaded connection, pin connection, magnetic connection, etc., or they can be non-detachably connected by means of bonding, welding, hot pressing, etc.

[0083] In one embodiment, reference is made to Figure 2 The first housing 17 and the second housing 18 are separate parts and fixedly connected; and the first housing 17 and the second housing 18 are arranged opposite each other along the width direction H2 of the box.

[0084] Designing the first housing 17 and the second housing 18 as separate components reduces the complexity of the required molds and improves the manufacturing precision of the first housing 17 and the second housing 18.
