Description

Technical Field

[0001] This utility model relates to the field of luggage equipment technology, specifically to an electric luggage with a fixing device. Background Technology

[0002] In today's fast-paced life, electric suitcases, with their convenience and efficiency, are gradually becoming the first choice for travelers and business people. However, despite the many advancements in the functionality and design of electric suitcases, the issue of removing and installing the wheels has always been a major technical challenge for both users and the industry. This article will focus on this technical background and delve into the drawbacks of the difficulty in removing and installing the wheels of electric suitcases under current technology.

[0003] Traditional electric suitcases often use a one-piece or fastener-fixed wheel design. A one-piece wheel design, where the wheel is directly cast or welded to the suitcase body, while enhancing the overall integrity of the suitcase and the stability of the wheel to some extent, causes significant inconvenience for users when the wheel needs replacement or repair. Because the connection between the wheel and the suitcase body is robust and complex, users often need specialized tools or even professional repair personnel to disassemble and reassemble the wheel. This not only increases maintenance costs but also prolongs repair time and reduces the user experience.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide an electric suitcase with a fixing device that can effectively solve the above-mentioned technical problems.

[0027] like Figures 1 to 4As shown, an electric suitcase with a fixing device includes a suitcase body 1 with a power unit 11, a drive wheel 2 located on one side of the suitcase body 1 and mechanically connected to the power unit 11, a pull rod 3 located inside the suitcase body 1, a plug-in interface 30 located at one end of the pull rod 3, a mounting groove 4 located at one end of the suitcase body 1, an assembly block 5 located in the mounting groove 4 and having an opening 50, a fixing shell 6 covering the mounting groove 4 and having a clamping member 61, a T-shaped shaft 7 plugged into the clamping member 61 and having a main bearing 71, and rollers 8 located on both sides of the T-shaped shaft 7; wherein, One end of the T-shaped shaft 7 passes through the opening 50 and is connected to the pull rod 3. The clamping member 61 retracts through the opening 50 and clamps the main bearing 71. The fixed shell 6 and the assembly block 5 cooperate to form a fixing device, so that the T-shaped shaft 7 is snapped to one end of the housing 1 through the fixed shell 6, and the roller 10 is snapped to one end of the housing 1 through the T-shaped shaft 7. In this embodiment, by setting the clamping member 61 to cooperate with the assembly block 5, the T-shaped shaft 7 with the roller 8 is detachably connected to one end of the housing 1 through the fixed shell 6, which can effectively reduce the difficulty of disassembly and assembly in this embodiment and facilitate user disassembly and maintenance.

[0028] A secondary bearing 51 is provided at one end of the opening 50. In this embodiment, the secondary bearing 51 is located at the end of the opening 50 near the insertion interface 30. By providing the secondary bearing 51, the connection position of the T-shaped shaft 7 can be further defined, making it easier for the T-shaped shaft 7 to be connected to the insertion interface 30. Furthermore, during use, by providing the secondary bearing 51 to cooperate with the main bearing 71, the steering effect of this embodiment can be further enhanced.

[0029] The clamping member 61 and the fixed shell 6 are an integral structure. One end of the clamping member 61 is provided with several clamping plates 62 for clamping the main bearing 71. There is a gap between any two adjacent clamping plates 62. One end of the clamping plate 62 is provided with an auxiliary locking block 63. In this embodiment, one side of the auxiliary locking block 63 is provided with an arc surface. The arc surface makes it convenient for the user to insert the clamping plate 62 into the opening 50. When the user inserts the clamping member 61 into the opening 50, the auxiliary locking block 63 abuts against the locking slot 50, thereby reducing the gap between two adjacent clamping plates 62, so that the clamping plate 62 locks the main bearing 71, making it convenient for the clamping member 61 to clamp the main bearing 71, and making the clamping member 61 lock into the opening 50, reducing the difficulty of connecting the clamping member 61 and the assembly block 5, and making it convenient for the user to disassemble and assemble.

[0030] Furthermore, the end of the T-shaped shaft 7 away from the roller 8 is provided with a snap-fit ​​groove 9, and the insertion interface 30 is provided with a snap-fit ​​block for engaging with the snap-fit ​​groove 9; in this embodiment, the cross-sectional shape of the snap-fit ​​block is rectangular. By setting the snap-fit ​​block to engage with the snap-fit ​​groove 9, it is convenient for the T-shaped shaft 7 to engage with the pull rod 3 and to limit and lock, so as to prevent the T-shaped shaft 7 and the pull rod 3 from rotating axially.

[0031] The housing 1 is screwed to the assembly block 5, and one side of the assembly block 5 is provided with several first screw holes 10. One side of the fixing shell 6 is provided with several second screw holes 60 corresponding to the first screw holes 10. The fixing shell 6 covers the mounting groove 4 and is fixed to one side of the housing 1 through the screw connection between the second screw holes 60 and the first screw holes 10. The assembly block 5 is located between the housing 1 and the fixing shell 6, so that both the fixing shell 6 and the assembly block 5 are fixed to one side of the housing 1. It is worth noting that in this embodiment, the assembly block 5 is located in the mounting groove 4, and the mounting groove 4 is provided with a connecting block. The assembly block is provided with a connecting groove for insertion into the connecting block. By inserting the connecting block into the connecting groove, the connection position of the assembly block 5 can be effectively defined, which further facilitates user assembly.

[0032] One end of the lever 3 is provided with a control handle 32 connected to the power device 11 by a wire. The control handle is provided with a control button 33. In this embodiment, the control handle 32 is a rotatable handle. The power device 11 includes a power source and a motor connected to the power source wire. The motor is mechanically connected to the drive wheel 2. The control handle 32 is connected to the motor wire, and the control button 33 is connected to the power source wire. The user rotates the control handle 32 to make the power device 11 control the drive wheel 2 to move.

[0033] Working principle: The assembly block 5 is inserted into the mounting groove 4, and one end of the T-shaped shaft 7 is inserted into the fixed shell 6, so that the main bearing 71 is located in the clamping member 61; then, the fixed shell 6 is covered on the mounting groove 4, and the clamping member 61 is inserted into the opening 50. The T-shaped shaft 7 is rotated so that the locking block engages with the locking groove 9, and one end of the T-shaped shaft 7 passes through the opening 50 and is inserted into the pull rod 3. The clamping member 61 retracts through the opening 50 and clamps the main bearing 71; finally, the second screw hole 60 is screwed into the first screw hole 10 to lock the fixed shell 6 and the housing 1.
