[0045] According to a first aspect of an embodiment of the present application, a moving mechanism 100 is provided. Figures 1 to 13 The structure and working principle of the moving mechanism 100 will be described in detail.

[0046] According to the mobile mechanism 100 provided in the embodiment of the present application, the mobile mechanism 100 includes a main body 110 and a plurality of wheel assemblies 120. The wheel assembly 120 includes a wheel member 121 and a bracket 130 that are detachably connected to each other, and the bracket 130 is disposed on the main body 110. The bracket 130 of at least one of the aforementioned plurality of wheel assemblies 120 is movably connected to the main body 110, so that the wheel rim of the wheel member 121 of at least one of the aforementioned one away from the side of the main body 110 can be close to the main body 110. In an embodiment, the aforementioned at least one further includes a locking member 140, which is connected to the bracket 130 of the aforementioned at least one, and the locking member 140 is configured to lock the position of the bracket 130 of the aforementioned at least one relative to the main body 110 and to release the locking of the position of the bracket 130 of the aforementioned at least one relative to the main body 110.

[0047] In this way, according to the mobile mechanism 100 provided in the embodiment of the present application, when it is necessary to replace the wheel component 121 of the mobile mechanism 100, the mobile mechanism 100 can be supported first, and then the lock of the bracket 130 of at least one of the aforementioned multiple wheel assemblies 120 relative to the main body 110 can be released, so that the rim of the wheel component 121 on the side away from the main body 110 can be close to the main body 110. In this way, the wheel component 121 changes from a state originally supported on the ground to a state detached from the ground, thereby no longer supporting the mobile mechanism 100 and can be removed from the bracket 130; and when there is no need to remove the wheel component 121, the locking component 140 can be used to lock the position of the bracket 130 relative to the main body 110, thereby preventing the bracket 130 from being subjected to force and moving during the movement of the mobile mechanism 100 using the wheel assembly 120. Therefore, according to the mobile mechanism 100 provided in the embodiment of the present application, the movable performance of the bracket 130 is utilized to drive the wheel component 121 close to the main body 110 to leave the ground, thereby avoiding the situation where the mobile mechanism 100 needs to be lifted to obtain space for replacing the wheel component 121 to a certain extent.

[0048] In an embodiment, the main body 110 may include a plate-like structure, such as a rectangular plate-like structure, wherein the wheel member 121 may be located at the lower side of the plate-like structure, so that the wheel member 121 can roll on the ground and support the main body 110 .

[0049] In an embodiment, the wheel member 121 can be connected to the bracket 130 by a plug-in connection, for example. As an example, the wheel member 121 can be a whole including a roller, a roller (the shaft around which the roller rotates), a bearing seat and a bearing of the roller, in which the roller can rotate around the roller by the support of the bearing. On this basis, a plug-in portion 122 can be provided above the wheel member 121 as the aforementioned whole, and the plug-in portion 122 can be, for example, a rod-shaped plug-in portion 122, and the cylindrical rod-shaped plug-in portion 122 can be inserted into a hole pre-set on the bracket 130. After being inserted into place, the cylindrical rod-shaped plug-in portion 122 can serve as another rotation axis of the aforementioned whole, that is, the aforementioned whole can rotate with the axis of the plug-in portion 122 as the axis, thereby, the wheel member 121 and the bracket 130 together play the role of a substantial universal wheel.

[0050] In an embodiment, the movable connection between the bracket 130 and the main body 110 may be, for example, a hinge. In addition, a universal joint connection may also be adopted, which will be explained in detail in the subsequent description.

[0051] In an embodiment, the number of the wheel assemblies 120 may be, for example, three, four, five or even more. As an example, the number of the wheel assemblies 120 may be four, and the four wheel assemblies 120 may be respectively distributed at the four corners of the plate-like structure of the main body 110. In an embodiment, among the multiple wheel assemblies 120, the bracket 130 of one wheel assembly 120 may be movably connected to the main body 110, or the brackets 130 of multiple wheel assemblies 120 may be movably connected to the main body 110. In the example given in the embodiment of the present application, the brackets 130 of all the wheel assemblies 120 are movably connected to the main body 110, that is, each wheel assembly 120 includes the locking member 140 as described above.

[0052] According to the mobile mechanism 100 provided in the embodiment of the present application, the mobile mechanism 100 may further include a support member 150, and the support member 150 may be arranged one-to-one corresponding to at least one of the above-mentioned multiple wheel assemblies 120, each support member 150 may be arranged on the outer side of the corresponding wheel assembly 120, and the support member 150 may be configured to be located on the same side of the main body 110 as the wheel member 121 of the corresponding wheel assembly 120, so as to support the main body 110 when the wheel rim of the wheel member 121 of the corresponding wheel assembly 120 is close to the main body 110.

[0053] Thus, according to the mobile mechanism 100 provided in the embodiment of the present application, when it is necessary to replace at least one of the wheel assemblies 120, the support member 150 corresponding to the wheel assembly 120 is set to be located on the same side of the main body 110 as the wheel member 121, and the support member 150 can be used to replace the wheel member 121 to support the main body 110 when the rim of the wheel member 121 of the wheel assembly 120 is close to the main body 110. Therefore, according to the mobile mechanism 100 provided in the embodiment of the present application, the corresponding support member 150 can be used to support the main body 110 for the wheel member 121 that needs to be replaced without providing an external support structure, and the pressure applied to the wheel member 121 to be replaced without support prevents the rim of the wheel member 121 from approaching the main body 110.

[0054] In an embodiment, the support member 150 may be, for example, a support rod or a support block. As an example, the support rod may be placed under the main body 110, or may be connected to the lower part of the main body 110 in a detachable manner (e.g., connected to the lower part of the main body 110 by fasteners such as screws), and when the corresponding wheel member 121 is disassembled, the support member 150 may be removed. In addition, the support member 150 may also be a component that is always connected to the main body 110, which will be explained in the subsequent description.

[0055] According to the mobile mechanism 100 provided in the embodiment of the present application, the side (that is, the lower side) of the main body 110 where the wheel member 121 is located may have a groove 111 corresponding one-to-one with the support member 150, and the support member 150 may be hinged to the main body 110, and the support member 150 can be rotated relative to the main body 110 to be received in the groove 111.

[0056] In an embodiment, when using the support member 150 to remove the corresponding wheel member 121, the support member 150 can be rotated out of the groove 111 and supported on the ground. When the corresponding wheel member 121 is removed and replaced with a new wheel member 121, the support member 150 can be rotated back into the groove 111, thereby storing the support member 150 to avoid possible interference with the movement of the mobile mechanism 100.

[0057] In an embodiment, the support member 150 may be a support rod as described above, the groove 111 may be correspondingly strip-shaped, one end of the support rod may be hinged to the inner side of the groove 111, and when the support rod is rotated out, as the support rod rotates, the outer side of the support rod will abut against the inner wall of the groove 111 so that it cannot continue to rotate, and thus it is in place. The lower end of the support rod in place may be slightly higher than the rim of the corresponding wheel member 121 on the side away from the main body 110, so that the main body 110 can be supported by slightly tilting the moving mechanism 100 and using the support rod instead of the corresponding wheel member 121.

[0058] According to the mobile mechanism 100 provided in the embodiment of the present application, the locking member 140 may be slidably connected to the bracket 130, and the locking member 140 may include a locking portion 142, which may be configured to protrude from the outside of the bracket 130 and be received in the bracket 130 when the locking member 140 slides relative to the bracket 130. In an embodiment, the locking portion 142 protruding from the outside of the bracket 130 can abut against the body 110 to lock the position of the bracket 130 relative to the body 110.

[0059] In this way, according to the mobile mechanism 100 provided in the embodiment of the present application, the locking member 140 uses a locking portion 142 that can extend from the outside of the bracket 130 and be received in the bracket 130 to lock the position of the bracket 130 relative to the main body 110. Since the locking portion 142 is received in the bracket 130 when the bracket 130 is unlocked relative to the main body 110, the structure of the mobile mechanism 100 is more compact.

[0060] According to the mobile mechanism 100 provided in the embodiment of the present application, the locking member 140 may include a locking body 141 and a connecting portion 143. In the embodiment, the locking body 141 may be attached to the bracket 130, and the locking portion 142 may be connected to the locking body 141, wherein the locking portion 142 may be inserted into the bracket 130. The connecting portion 143 may be connected to the locking body 141, and the connecting portion 143 may be inserted into the bracket 130 and may slide relative to the bracket 130, wherein the connecting portion 143 and the locking portion 142 may be located on opposite sides of the locking body 141.

[0061] Thus, according to the mobile mechanism 100 provided in the embodiment of the present application, the locking body 141 of the locking member 140 can slide in contact with the bracket 130, thereby providing a certain stability for the sliding of the locking member 140. As an example, the side of the bracket 130 facing the wheel member 121, that is, the lower side of the bracket 130, can be a plane 135, and the plane 135 can, for example, be in contact with the sheet-like locking body 141, thereby further improving the stability of the locking member 140 when sliding.

[0062] In an embodiment, the locking portion 142 may be, for example, a strip-shaped structure, one end of the locking portion 142 may be connected to the upper side of the locking body 141, and the other end may extend beyond one side of the locking body 141. As an example, the number of the locking portions 142 may be, for example, two, and the two locking portions 142 may be arranged parallel to each other.

[0063] In an embodiment, the lower side of the bracket 130 may be provided with a slide groove 131 for inserting the locking portion 142, a portion of the slide groove 131 is open for inserting the locking portion 142, another portion of the slide groove 131 is located inside the bracket 130, and the end of the slide groove 131 forms a slot 132 exposed to the outside of the bracket 130, and the locking portion 142 extends from the slot 132 to the outside of the bracket 130 to lock the bracket 130.

[0064] In an embodiment, the connection portion 143 may protrude from the upper side of the locking body 141. The connection portion 143 may be a rectangular structure as a whole, wherein the middle portion may have a through portion 144. The lower side of the bracket 130 may have a slot 133 corresponding to the connection portion 143. The slot 133 may be, for example, in an "L" shape. When the connection portion 143 is inserted into the slot 133, as the locking member 140 slides, the portion of the connection portion 143 located on the upper side of the through portion 144 further moves into the slot 133, so that the connection portion 143 is substantially sleeved on the outside of a part of the structure of the bracket 130. In this way, the connection portion 143 is used to share the force of the locking portion 142, thereby increasing the strength of the locking member 140 and preventing the locking portion 142 from being deformed by force. At the same time, the connection portion 143 and the locking portion 142 are respectively located on both sides of the locking body 141, which is conducive to ensuring that the locking member 140 is uniformly stressed.

[0065] In an embodiment, the locking body 141 may have an opening portion 145 (e.g., a waist-shaped hole) extending along the sliding direction of the locking member 140 (when the locking member 140 locks the bracket 130, the direction is substantially a horizontal direction), and the wheel member 121 includes the above-mentioned plug-in portion 122, which is passed through the opening portion 145 and inserted into the bracket 130, thereby making the structure of the mobile mechanism 100 more compact.

[0066] According to the mobile mechanism 100 provided in the embodiment of the present application, the main body 110 may have a recess 113 provided corresponding to the locking portion 142, and the locking portion 142 protruding from the outside of the bracket 130 can be inserted into the recess 113 to lock the position of the bracket 130 relative to the main body 110. As an example, the main body 110 may have a locking plate 112 provided on the upper side of the plate-like structure, and the locking plate 112 may be provided with the aforementioned recess 113, and the plate may be provided facing the bracket 130, and when the locking portion 142 extends from the bracket 130, the end of the locking portion 142 is inserted into the recess 113, thereby achieving reliable locking of the bracket 130 relative to the main body 110.

[0067] As mentioned in the above description, according to the mobile mechanism 100 provided in the embodiment of the present application, the movable bracket 130 can be hinged with the main body 110, so that the bracket 130 can swing relative to the main body 110. Specifically, two small bearings 180 can be pre-embedded on both sides of the bracket 130, and two seat components 115 opposite to each other can be set on the upper side of the plate-like structure of the main body 110, and the two seat components 115 are respectively located on both sides of the bracket 130. Two large bearings 190 can be respectively embedded in the two seat components 115, and then the corresponding large bearings 190 and small bearings 180 are penetrated by the rotating shaft, so that the bracket 130 can swing relative to the seat component 115.

[0068] In the embodiment, a stop groove may be provided on the upper side of the main body 110, corresponding to a side of each seat member 115 away from the bracket 130. When the large bearing 190 is installed in the seat member 115, the bearing baffle 191 may be inserted into the stop groove, and then the bearing baffle 191 may be connected to the seat member 115 using a fastener such as a bolt 160. In addition, nuts 170 may be pre-embedded on both sides of the bracket 130 facing the two seat members 115, respectively. The bolts 160 on the two seat members 115 may further penetrate the seat members 115 where they are located and be connected to the corresponding nuts 170, thereby further locking the bracket 130 to prevent the bracket 130 from shaking.

[0069] Thus, according to the mobile mechanism 100 provided by the embodiment of the present application, when the bracket 130 is not locked, the bracket 130 and the wheel member 121 are respectively located on two opposite sides of the main body 110, that is, the bracket 130 is located on the upper side of the main body 110, and the wheel member 121 is located on the lower side of the main body 110. In the embodiment, the main body 110 (that is, the plate-like structure of the main body 110) may have a hole portion 114, and the hole portion 114 is used to avoid the swing of the bracket 130. Specifically, the side of the bracket 130 away from the wheel member 121 is an arc surface 134. When the bracket 130 swings relative to the main body 110, the arc surface 134 of the bracket 130 swings and passes through the hole portion 114, and is partially located on the lower side of the main body 110. This is a state in which the wheel member 121 is tilted, and its lower side wheel rim is detached from the ground, so that the mobile mechanism 100 is not supported, and space is obtained to be pulled off from the bracket 130.

[0070] According to a second aspect of an embodiment of the present application, a mobile energy storage device is provided. The mobile energy storage device includes a mobile mechanism 100 and an energy storage mechanism 200. The energy storage mechanism 200 is connected to the main body 110, for example, installed above the plate-like structure of the main body 110. In an embodiment, the energy storage mechanism 200 has a battery and can supply power to the outside.

[0071] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. All equivalent structural changes made by using the contents of the present application specification and drawings under the innovative concept of the present application, or directly / indirectly applied in other related technical fields are included in the protection scope of the present application.
