However, existing products often fail to meet these requirements. Utility Model Content

[0003] This application provides a quick-release structure, which uses a simple magnetic attraction and locking method by combining a first assembly and a second assembly. This structure is applicable to most devices that require a quick-release structure, thus avoiding the problem that it can only be applied to a small number of devices.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] A quick-release structure is provided, characterized in that it comprises: a first assembly and a second assembly. The first assembly has a first body, a first connecting member, and an elastic member. The first body has a first receiving groove, the first connecting member is disposed within the first receiving groove, and the elastic member is disposed at the opening of the first receiving groove. The second assembly has a second body and a second connecting member. The second body has a boss, the end face of which has a second receiving groove. The second connecting member is disposed within the second receiving groove. The end face of the boss has two opposing locking sides and two opposing unlocking sides. The end face of the boss of the second assembly is assembled into the first receiving groove of the first assembly, and the first connecting member and the second connecting member are mutually attracted and fixed. When the locking side of the end face of the boss corresponds to the elastic member, the first assembly and the second assembly are in a locked state; when the unlocking side of the end face of the boss corresponds to the elastic member, the first assembly and the second assembly are in an unlocked state.

[0006] In one embodiment, the first coupling is a magnetic element, and the second coupling is either a magnetic element or a magnetic attraction element.

[0007] In one embodiment, a fixing cover is further included, the fixing cover being disposed on the side of the first body having the elastic element, the fixing cover fixing the elastic element, the fixing cover having a channel corresponding to the elastic element, the channel communicating with the first receiving groove.

[0008] In one embodiment, the first assembly further includes a first turntable disposed on the periphery of the channel opening away from the elastic member, the first turntable having at least one protrusion on its surface, and the second assembly includes a second turntable disposed on the periphery of the protrusion, the second turntable having a plurality of grooves on its surface, the at least one protrusion of the first turntable engaging with one of the plurality of grooves of the second turntable.

[0009] In one embodiment, the protrusion is an arc surface, the plurality of grooves are arc grooves, and the protrusion slides on the plurality of grooves.

[0010] In one embodiment, the first turntable has a first mark on its side and the second turntable has a second mark on its side. When the first mark is rotated to correspond to the second mark, the first assembly and the second assembly are in an unlocked or locked state.

[0011] In one embodiment, the elastic member has two fixing portions and a connecting portion, with two fixing portions at each end of the connecting portion, and the two fixing portions protruding into the opening of the first receiving groove.

[0012] In one embodiment, the fixing portion of the elastic member has a first guide side relative to one side of the second assembly, and the locking side has a second guide side relative to one side of the first assembly, wherein when the end face of the boss is inserted into the first receiving groove, the second guide side of the locking side of the end face of the boss abuts against the first guide side of the elastic member.

[0013] In one embodiment, the first connector has a through hole, and the second connector has a protrusion, one end of which is an arc surface, and one end of the protrusion of the second connector is fitted into the through hole of the first connector.

[0014] In one embodiment, the outer diameter of the locking side is greater than the outer diameter of the unlocking side.

[0015] In one embodiment, the elastic element has a fixing protrusion on one side adjacent to the first body, and the first body has a fixing recess on one side opposite to the elastic element, wherein the fixing protrusion of the elastic element is fitted into the fixing recess of the first body.

[0016] The quick-release structure of this application uses magnetic attraction between the first and second assemblies for fixation. During rotation, the first and second assemblies can switch between locked and unlocked states. When rotated to the locked state, the first and second assemblies are not only magnetically secured but also structurally restricted by their internal components. When rotated to the unlocked state, the first and second assemblies are only magnetically secured; applying a force greater than the magnetic attraction allows the second assembly to be detached from the first assembly. Thus, this quick-release structure facilitates rapid disassembly and assembly. Attached Figure Description

However, it should be understood that these implementation details are not intended to limit the application. That is, in some embodiments of this application, these implementation details are not essential.

In the following embodiments, the same or similar components will be represented by the same reference numerals.

[0028] Please see Figures 1 to 8 , Figure 1 This is an exploded view of the quick-release structure of this application. Figure 2 It is another exploded diagram. Figure 3 Is it unlocking the 3D map? Figure 4 yes Figure 3 A sectional view of line A-A' Figure 5 This is an internal unlocking diagram. Figure 6 It is a locking 3D diagram. Figure 7 yes Figure 6 The cross-sectional view of line B-B' and Figure 8This is a schematic diagram of the internal locking mechanism. As shown in the figure, this application provides a quick-release structure 1, which includes a first assembly 11 and a second assembly 12. The first assembly 11 has a first body 111, a first connecting member 112, and an elastic member 113. The first body 111 has a first receiving groove 1111. The first connecting member 112 is disposed at the bottom of the first receiving groove 1111. The elastic member 113 is disposed at the opening of the first receiving groove 1111. The second assembly 12 has a second body 121 and a second connecting member 122. The second body 121 has a boss 1211, and the end face of the boss 1211 has a second receiving groove 1212. The second coupling member 122 is disposed in the second receiving groove 1212. The end face of the boss 1211 has two opposing locking sides 1213 and two opposing unlocking sides 1214 around its perimeter. The end face of the boss 1211 of the second assembly 12 is assembled into the first receiving groove 1111 of the first assembly 11. The first coupling member 112 and the second coupling member 122 can be attracted to each other or connected and fixed. Alternatively, the above structure is achieved by the locking side 1213 of the boss 1211 being fixed by the fixing part 1131 of the elastic member 113. The relative positions of the first assembly 11 and the second assembly 12 are restricted. When the locking side 1213 of the end face of the boss 1211 corresponds to the elastic member 113, the first assembly 11 and the second assembly 12 are locked, meaning the boss 1211 of the second assembly 12 cannot disengage from the first receiving groove 1111 of the first assembly 11. When the unlocking side 1214 of the end face of the boss 1211 corresponds to the elastic member 113, the first assembly 11 and the second assembly 12 are unlocked, meaning the boss 1211 of the second assembly 12 can disengage from the first receiving groove 1111 of the first assembly 11. This embodiment does not limit the electronic device or structure to which the first body 111 and the second body 121 are applied. Users can replace the structure of the first body 111 and the second body 112 as needed, or place the first body 111 and the second body 121 on the required electronic device or assembly structure that requires quick-release.

[0029] As described above, the first assembly 11 further includes a fixing cover 114, which is disposed on the side of the first body 111 where the elastic member 113 is located. The fixing cover 114 fixes the elastic member 113, that is, the fixing cover 114 and the first body 1111 clamp and fix the elastic member 113. The elastic member 113 has a fixing protrusion 1134 on the side adjacent to the first body 111, and the first body 111 has a fixing recess 1112 on the side opposite to the elastic member 113. The fixing protrusion 1134 of the elastic member 113 fits into the fixing recess 1112 of the first body 111, thereby restricting the position of the elastic member 113 relative to the first body 1111, so that the elastic member 113 is fixed in the groove of the first receiving groove 1111. The fixing cover 114 has a channel 1141, which corresponds to the elastic member 113 and communicates with the first receiving groove 1111. The elastic element 113 has two fixing parts 1131 and a connecting part 1132. The two ends of the connecting part 1132 extend and connect to the two fixing parts 1131 respectively. The two fixing parts 1131 protrude into the opening of the first receiving groove 111.

[0030] Please refer to the following: Figure 4 and Figure 5 The distance between adjacent sides of the two fixing portions 1131 of the elastic member 113 is greater than the outer diameter length of the two opposite unlocking sides. Thus, when the unlocking side 1214 of the end face of the boss 1211 corresponds to the fixing portion 1131 of the elastic member 113, the unlocking side 1214 is not restricted by the fixing portion 1131. In other words, the boss 1211 of the second assembly 12 can freely enter and exit the first receiving groove 1111 of the first assembly 11. Please refer to [further details needed]. Figure 6 The distance between adjacent sides of the two fixing portions 1131 of the elastic member 113 is less than the outer diameter length of the two opposing locking sides 1213. Thus, when the locking side 1213 of the end face of the boss 1211 corresponds to the fixing portion 1131 of the elastic member 113, the locking side 1213 is restricted by the fixing portion 1131. In other words, the boss 1211 of the second assembly 12 is restricted within the first receiving groove 1111 of the first assembly 11.

[0031] As mentioned above, the outer diameter of the two opposing locking sides 1213 is greater than the outer diameter of the two opposing unlocking sides 1214. The sides of the two opposing locking sides 1213 are rounded, while the sides of the two opposing unlocking sides 1214 are straight.

[0032] Furthermore, when the boss 1211 of the second assembly 12 enters the first receiving groove 1111 of the first assembly 11 with its unlocking side 1214, the unlocking side 1214 of the boss 1211 is not restricted by the fixing portion 1131 of the elastic member 113. When the boss 1211 of the second assembly 12 enters the first receiving groove 1111 of the first assembly 11 with its locking side 1213, the locking side 1213 of the boss 1211 is affected by the fixing portion 1131 of the elastic member 113. The fixing portion 1131 of the elastic member 113 has a first guide side 1133 on one side relative to the second assembly 12, and two opposing locking sides 1213 have second guide sides 1215 on one side relative to the first assembly 11. When the end face of the boss 1211 is inserted into the first receiving groove 1111, the second guide side 1215 of the locking side 1213 of the end face of the boss 1211 naturally abuts against the first guide side 1133 of the elastic member 113, allowing the boss 1211 to open the elastic member 113, and then the end face of the boss 1211 enters the first receiving groove 1111. The second guide side 1215 and the first guide side 1133 facilitate the insertion of the end face of the boss 1211 into the first receiving groove 1111, so that the second assembly 12 is installed in the first assembly 11. Thus, the insertion of the boss 1211 of the second assembly 12 into the first receiving groove 1111 of the first assembly 11 is not restricted, that is, the locking side 1213 or unlocking side 1214 of the boss 1211 into the fixing part 1131 of the elastic member 113 is not restricted in assembly.

[0033] In this embodiment, when the end face of the boss 1211 is inserted into the first receiving groove 1111, the end face of the boss 1211 has a second connecting member 122, and the first receiving groove 1111 has a first connecting member 112. The first connecting member 112 has a through hole 1121, and the second connecting member 122 has a protrusion 1221. The protrusion 1221 is a cylinder, and one end of the protrusion 1221 is also an arc surface. One end of the protrusion 1221 of the second connecting member 122 is fitted into the through hole 1121 of the first connecting member 112. The protrusion 1221 can also be other different shapes that can be fitted into the through hole 1121. When the second assembly 12 rotates relative to the first assembly 11, the arc surface of one end of the protrusion 1221 of the second assembly 122 can rotate within the through hole 1121 of the first assembly 112. The structure design of the cylinder and the hole can effectively stabilize the first assembly 11 and the second assembly 12, making it less prone to shaking during the rotation process.

[0034] Furthermore, the first connecting member 112 can be a magnetic component, and the second connecting member 122 can be either a magnetic component or a magnetic attraction component. The magnetic component can be a magnet structure of various types, and the magnetic attraction component can be a metallic material that can be attracted to a magnet. This embodiment does not limit the magnetic structural relationship between the first connecting member 112 and the second connecting member 122. The first connecting member 112 and the second connecting member 122 can be adjusted to a mutually magnetically attracted and fixed relationship according to the user's needs. In this embodiment, in addition to being magnetically attracted and fixed, the first connecting member 112 and the second connecting member 122 can also be interlocked, thereby strengthening the structural connection strength between the first connecting member 112 and the second connecting member 122. Moreover, the first connecting member 112 and the second connecting member 122 are not limited to magnetic materials. The user can select the materials and structures of the first connecting member 112 and the second connecting member 122 according to their needs.

[0035] Please see Figure 6 to and Figure 8 In this embodiment, when the second assembly 12 is assembled and fixed with the first assembly 11, the boss 1211 of the second assembly 12 is inserted into the first receiving groove 1111 of the first assembly 11. The second connecting member 122 of the second assembly 12 and the first connecting member 112 of the first assembly 11 are attracted and fixed to each other. At the same time, when the locking side 1213 of the end face of the boss 1211 of the second assembly 12 corresponds to the fixing part 1131 of the elastic member 113, the locking side 1213 is restricted by the fixing part 1131. Thus, the second assembly 12 and the first assembly 11 are locked together.

[0036] Please see Figures 3 to 5 When the second assembly 12 is disassembled from the first assembly 11, the second assembly 12 is rotated relative to the first assembly 11, so that the unlocking side 1214 of the end face of the boss 1211 of the second assembly 12 corresponds to the fixing part 1131 of the elastic member 113. The unlocking side 1214 is not restricted by the fixing part 1131, and the boss 1211 of the second assembly 12 can freely enter and exit the first receiving groove 1111 of the first assembly 11. If the force applied to remove the second assembly 12 is greater than the magnetic force between the second connector 122 and the first connector 112, the second assembly 12 can be detached from the first assembly 11.

[0037] Furthermore, the first assembly 11 further includes a first turntable 115, which is disposed on the fixed cover 114 and located on the periphery of the channel 1 away from the channel opening of the elastic member 113. The table surface of the first turntable 115 has at least one protrusion 1151. The second assembly 12 includes a second turntable 123, which is disposed on the periphery of the protrusion 1211. The table surface of the second turntable 123 has a plurality of grooves 1231, and at least one protrusion 1151 of the first turntable 115 is fitted into one of the plurality of grooves 1231 of the second turntable 123. When the first assembly 11 rotates relative to the second assembly 12, the protrusion 1151 of the first turntable 115 moves within the multiple grooves 1231 of the second turntable 123. This movement of the protrusion 1151 within the grooves creates a tactile, up-and-down engagement feel, allowing the user to clearly perceive a specific rotational feel for each angle of rotation of the first assembly 11 relative to the second assembly 12. In other words, this design allows the assembly to have clear positions and locations at each angle during rotation. Due to the magnetic attraction, each rotation provides a distinct tactile feel, allowing the user to more clearly understand the effect of the rotation being complete.

[0038] Please also refer to Figure 3 and Figure 5 The first turntable 115 has a first mark 1152 on its side, and the second turntable 123 has a second mark 1232 on its side. When the first mark 1152 is rotated to correspond to the second mark 1232, the first assembly 11 and the second assembly 12 are either in an unlocked or locked state. This makes it easy for the user to know the structural state of the quick-release structure 1.

[0039] In summary, the quick-release structure of this application uses magnetic attraction between the first and second assemblies for fixation. Specifically, the magnetic force within the first body expands the elastic element, allowing it to connect. Even with materials lacking magnetic attraction, external force can be used to open the elastic element. During rotation, the first and second assemblies can switch between locked and unlocked states. When locked, they are subject to both magnetic attraction and internal structural constraints. When unlocked, they are only magnetically secured; applying a force greater than the magnetic attraction allows the second assembly to be detached from the first assembly. Thus, this quick-release structure facilitates rapid disassembly and assembly.

[0040] The foregoing description illustrates and describes several preferred embodiments of this application. However, as previously stated, it should be understood that this application is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein, through the foregoing teachings or the technology or knowledge in related fields.
