[0024] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Please see Figures 1 to 7The present invention preferably provides the following technical solution: a wheel structure for an electric suitcase, comprising: an electric suitcase 1, and a wheel structure 2 assembled to the bottom of the electric suitcase 1, the wheel structure 2 having two switching modes: directional and omnidirectional; the wheel structure 2 includes a fixed base, the side wall and top of the fixed base are respectively equipped with a release limit lever and a limit locking assembly, the limit locking assembly being assembled perpendicularly to the release limit lever; and the wheel structure 2 assembled on the fixed base; the wheel structure 2 includes a wheel 211, and an mounting rod 212 assembled on the top of the wheel 211, the side wall of the mounting rod 212 having an arc-shaped limit groove 2121, which can be used for directional limit of the wheel 211 when the release limit lever is inserted into the arc-shaped limit groove 2121, and can be used for free omnidirectional rotation of the wheel 211 when the release limit lever is disengaged from the arc-shaped limit groove 2121.

[0027] The wheel structure 2 in this application is a switching mechanism that can switch between omnidirectional and directional states, allowing for free switching according to the usage scenario. It not only retains the existing advantages of existing electric suitcases but also adds new functions, enriching the product experience. When the electric suitcase 1 is being ridden, the wheel structure 2 is in a directional state. When the suitcase is not being ridden, the user can manually adjust the directional state to an omnidirectional state, facilitating dragging or pushing and enhancing the overall user experience of electric suitcases.

[0028] Specifically, such as Figure 1 , 2 As shown in Figures 3 and 4, the interaction between the release limit rod and the limit snap-fit ​​assembly, as well as the arc-shaped limit groove 2121 opened on the side wall of the wheel structure 2;

[0029] When it is necessary to switch to the universal state, the release limit lever can be pulled horizontally to disengage the release limit lever from the arc-shaped limit groove 2121, thereby canceling the directional limit of the wheel structure 2;

[0030] When it is necessary to switch to the directional state, the linkage limit tab can be pulled upwards. The spring force of the limit pull rod will release the limit pull rod and re-engage it with the arc-shaped limit groove 2121, thus switching back to the directional limit.

[0031] Example 2

[0032] In another embodiment of this utility model, the fixing seat includes a seat body 251, which has a U-shaped structure. A first through groove 252 is opened at the end of the seat body 251 and is used to release the insertion and assembly of the limiting rod. A second through groove 253 is opened at the end of the seat body 251 and is perpendicular to the first through groove 252. An assembly block 254 is fixedly assembled on the top of the second through groove 253. An installation block 221 is also fixed at the end of the seat body 251. An installation hole 223 is passed through the middle of the installation block 221 and is used for the vertical assembly of the mounting rod 212. An elongated groove 222 is distributed perpendicularly to the installation hole 223 and communicates with the first through groove 252 and is used to release the insertion and limiting of the limiting rod and the arc-shaped limiting groove 2121.

[0033] Furthermore, the release limit lever includes a first horizontal lever 234 and horizontal insertion posts 232 connected to the end of the first horizontal lever 234 and vertically distributed. An installation ring 233 for lateral assembly of the horizontal insertion posts 232 is fixed in the long groove 222. The end of each horizontal insertion post 232 away from the first horizontal lever 234 passes through the installation ring 233 and is provided with a limit plug 231 that is adapted to be inserted into the arc-shaped limit groove 2121. A first return spring 235 is connected to the outer wall of the horizontal insertion post 232 between the installation ring 233 and the first horizontal lever 234. Two limit slots 236 are opened on the top of the horizontal insertion post 232, which are respectively used for the limit insertion of the limit engagement assembly when the horizontal insertion post 232 is in different positions.

[0034] Furthermore, the limiting engagement assembly includes a second horizontal tie rod 246 and vertical inserts 242 mounted at both ends of the second horizontal tie rod 246. The bottom of each vertical insert 242 extends through a through hole on the assembly block 254 into the interior of the second through groove 253 and is connected to a transmission block 241. A second return spring 243 is connected to the outer wall of the vertical insert 242 between the transmission block 241 and the assembly block 254. A limiting block 245 is fixed on the transmission block 241 and is perpendicularly distributed thereto. The limiting block 245 can be limited and engaged with the limiting groove 236 on the horizontally arranged horizontal insert 232.

[0035] In this embodiment, the structural design further includes a fixed base, a release limit lever, and a limit locking assembly, such as... Figure 2 , 3 As shown in Figures 4 and 6, the limiting plug 231 is inserted into the arc-shaped limiting groove 2121 on the mounting rod 212. At this time, the rotation of the mounting rod 212 is limited by the limiting plug 231, and it can only rotate in one direction. When the first horizontal pull rod 234 is pulled outward laterally, the limiting block 245 is lifted along the position of the limiting groove 236 and disengages from the first limiting groove 236. When the limiting plug 231 is completely disengaged from the arc-shaped limiting groove 2121 and the wheel 211 is omnidirectional, the limiting block 245 engages and enters the second limiting groove 236 to lock its own position.

[0036] When switching from omnidirectional to directional mode, the second horizontal pull rod 246 can be lifted. At this time, the limiting block 245 where the transmission block 241 is located disengages from the second limiting slot 236. Under the elastic force of the first reset spring 235, the horizontal insertion post 232 is once again inserted into the arc-shaped limiting slot 2121 on the mounting rod 212, and the directional mode can be switched back. This design is simple to operate, easy to switch, and has high stability.

[0037] Example 3

[0038] As another embodiment of this utility model, the limiting slot 236 is provided with a slope in the direction of the mounting block 221, and the end face of the limiting block 245 near the mounting block 221 is provided with a chamfer. When the first horizontal tie rod 234 moves away from the mounting block 221 to unlock the wheel 211, the chamfer of the limiting block 245 is raised along the slope of the limiting slot 236.

[0039] like Figure 7 As shown, the further chamfered corner and the slope where the limiting slot 236 is located provide a stable limiting effect when the limiting block 245 engages with the limiting slot 236. At the same time, when the first horizontal pull rod 234 is pulled outward to release the limiting effect, it facilitates the disengagement of the limiting block 245 from the limiting slot 236.

[0040] Furthermore, the arc radius of the arc-shaped limiting groove 2121 is greater than or equal to the radius of the limiting plug 231, and the outer wall of the limiting plug 231 is provided with a damping layer.

[0041] The radius of the arc-shaped limiting groove 2121 is greater than or equal to the radius of the limiting plug 231, facilitating the insertion-type limiting assembly of the limiting plug 231 and the arc-shaped limiting groove 2121. Figure 6 As shown, when the wheel 211 is adjusted to the directional position for riding the electric luggage box 1, the damping layer enables the limit plug 231 to be tightly inserted into the arc-shaped limit groove 2121, which can improve the directional stability of the wheel 211.

[0042] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. Among these, there are various ways to install detachably, such as by using a combination of plug-in and snap-fit, or by using bolts for connection, etc.

[0043] In addition, all the connections / connections mentioned in the article do not refer to direct connection of components, but rather to the formation of a better connection structure by adding or removing connecting accessories according to the specific implementation situation.

[0044] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
