Some examples of such products are cameras, phones, earphones, wearable fans, and helmets. The quick release structure must be designed to meet the different usage requirements to provide users with a good experience of usage. However, the existing products cannot meet these requirements.SUMMARYThe present invention provides a quick release structure that simply connects the first and second assemblies by means of magnetic attraction and a locking mechanism, which can be applied to most appliances requiring a quick release structure, thereby avoiding the problem of being applicable only to a few appliances.In order to solve the above technical problem, the present invention is implemented as follows.The present invention provides a quick release structure comprising a first assembly and a second assembly. The first assembly has a first body, a first combining piece, and an elastic member. The first body has a first retaining groove. The first combination piece is disposed in the first retaining groove. The elastic member is disposed at an opening of the first retaining groove. The second assembly has a second body and a second combination piece. The second body has a slope; an end face of the slope has a second retaining groove. The second combining piece is disposed in the second retaining groove. The slope has two locking sides and two unlocking sides on the front side, and the front side of the slope is fitted with the first retaining groove of the first assembly. The first combination piece and the second combination piece are magnetically fixed to each other; wherein when the locking sides of the slope on the end side correspond to the elastic part, the first assembly and the second assembly are in a locked state, and when the unlocking sides of the slope on the end side correspond to the elastic part, the first assembly and the second assembly are in an unlocked state.In one embodiment, the first combination piece is a magnetic member and the second combination piece is a magnetic member or a magnetically attracting member.In one embodiment, a fixed plate is provided, which is arranged on one side of the first body with the elastic part. The fixed plate fixes the elastic member and has a passage corresponding to the elastic member, and the passage is connected to the first retaining groove.In one embodiment, the first assembly includes a first rotating ring. The first rotating ring is arranged on the side of an opening of the passage facing away from the elastic part. A surface of the first rotating ring has at least one latching lug. The second combination piece further includes a second rotating ring disposed on the side of the slope; a surface of the second rotating ring has a plurality of recesses. The at least one latching lug of the first rotating ring engages in one of the plurality of depressions of the second rotating ring. The at least one latching lug of the first rotating ring engages in one of the plurality of depressions of the second rotating ring.In one embodiment, the detent has a curved surface and the recesses have curved grooves. The latching lug slides in the plurality of depressions.In one embodiment, one side of the first rotating ring has a first mark and one side of the second rotating ring has a second mark. When the first mark is rotated corresponding to the second mark, the first assembly and the second assembly are in an unlocked state or a locked state.In one embodiment, the elastic member has two fixed portions and connecting portions. The connecting portions have two fixed portions at opposite ends, and the two fixed portions project toward an opening of the first retaining groove.In an embodiment, the fixed portion of the elastic member has a first guide surface on one side relative to the second combination piece, and the locking side has a second guide surface on an opposite side relative to the first combination piece, wherein when an end face of the slope is inserted into the first retaining groove, the second guide surface of the locking side of the end face of the slope naturally contacts and enters the first guide surface of the elastic member.In one embodiment, the first combination piece has a through hole and the second combination piece has a pin. One end of the pin is curved. One end of the pin is received in the through hole.In an embodiment, an outer diameter length of the locking sides is greater than an outer diameter length of the unlocking sides.In one embodiment, the elastic part has a fixed latching nose on a side adjacent to the first body. The first body has a fixed recess on the side opposite to the elastic member. The fixed detent nose of the elastic part engages in the fixed depression of the first body.The quick release structure of the present invention uses magnetic attractive force to fix the first assembly and the second assembly to each other. During rotation of the first assembly and the second assembly, the two components may transition between a locked state and an unlocked state. When the first assembly and the second assembly are rotated to a locked state, in addition to being magnetically fixed, they are also limited by the inner structure. When the first assembly and the second assembly are rotated to an unlocked state, the two components are only magnetically fixed. By applying a force greater than the magnetic attractive force, the second assembly can be separated from the first assembly. This enables quick disassembly and assembly of the quick release structure of the present invention.Other objects, features and advantages of the present invention will be understood from the other technical features disclosed by the embodiments of the present invention, and preferred embodiments of the present invention will be shown and described merely for illustrating modes best suited to practice the invention.BRIEF DESCRIPTION OF THE DRAWINGSThe accompanying drawings serve to provide a better understanding of the present invention and are an essential part thereof.

As shown in the figures, the present invention provides a quick release assembly 1 comprising a first assembly 11 and a second assembly 12. The first assembly 11 includes a first body 111, a first combining piece 112, and an elastic part 113. The first body 111 has a first retaining groove 1111. The first combining piece 112 is disposed at a bottom of the first holding groove 1111. The elastic member 113 is disposed at an opening of the first holding groove 1111. The second assembly 12 includes a second body 121 and a second combining piece 122. The second body 121 has a slope 1211, and an end side of the slope 1211 has a second retaining groove 1212. The second combining piece 122 is disposed inside the second retaining groove 1212. The face of the slope 1211 has two opposite locking sides 1213 and two opposite unlocking sides 1214 surrounding them. The front side of the slope 1211 of the second assembly part 12 is inserted into the first retaining groove 1111 of the first assembly part 11, and the first combination piece 112 and the second combination piece 122 may be mutually attracted and / or firmly connected to each other. Alternatively, as described above, the structure is limited in its relative position by the locking side 1213 of the slope 1211 and the fixed portion 1131 of the elastic member 113 to limit the relative positions of the first assembly 11 and the second assembly 12. When the locking sides 1213 of the end face of the slope 1211 correspond to the elastic part 113, the first assembly 11 and the second assembly 12 are in a locked state, i.e., the slope 1211 of the second assembly 12 cannot disengage from the first retaining groove 1111 of the first assembly 11. When the unlocking sides 1214 of the end face of the slope 1211 correspond to the elastic part 113, the first assembly 11 and the second assembly 12 are in an unlocked state, i.e., the slope 1211 of the second assembly 12 can easily disengage from the first retaining groove 1111 of the first assembly 11. The present embodiment does not limit the application of the first body 111 and the second body 121 to electronic devices or structures. The user may replace the first body 111 and the second body 112 with appropriate structures according to the user's needs or attach the first body 111 and the second body 112 to the desired electronic devices or structures requiring a quick release arrangement.As described above, the first assembly 11 further includes a fixed plate 114. The fixed plate 114 is disposed on one side of the first body 111 with the elastic part 113. The fixed plate 114 fixes the elastic part 113; i.e. the fixed plate 114 and the first body 111 clamp the elastic part 113 together, wherein the elastic part 113 has a fixed detent 113 adjacent to a side of the first body 111, which side of the first body 111 faces the elastic part 113 and the first body 111 has a fixed depression 1112 relative to the elastic part 113. The fixed detent 1134 of the elastic member 113 is inserted into the fixed recess 1112 of the first body 111, thereby limiting the position of the elastic member 113 relative to the first body 111, so that the elastic member 113 is fixed to the opening of the first retaining groove 1111. The fixed plate 114 has a passage 1141 corresponding to the elastic member 113, and the passage 1141 is connected to the first retaining groove 1111, the elastic member 113 having two fixed portions 1131 and connecting portions 1132. The connecting portions 1132 have two ends, each of which extends to two fixed portions 1131. The two fixed portions 1131 protrude into the opening of the first holding groove 1111.Referring to FIGS. 4 and 5, the distance between the two fixed portions 1131 adjacent to each other on the elastic member 113 side is larger than the outer diameter length of the two opposite unlocking sides 1214. Thus, when the unlocking sides 1214 at the end side of the slope 1211 correspond to the fixed portions 1131 of the elastic member 113, the unlocking sides 1214 are not restricted or affected by the fixed portions 1131, i.e., the slope 1211 of the second assembly 12 can freely enter and exit the first retaining groove 1111 of the first assembly 11. Referring to FIG. 6, the distance between the two fixed portions 1131 adjacent to each other on the elastic member 113 side is smaller than the outer diameter length of the two opposite lock sides 1213. Thus, when the locking sides 1213 at the end side of the slope 1211 correspond to the fixed portions 1131 of the elastic member 113, the locking sides 1213 are restricted or affected by the fixed portions 1131, i.e., the slope 1211 of the second assembly 12 is restricted to be located within the first retaining groove 1111 of the first assembly 11.As described above, the outer diameter length of the two opposing lock sides 1213 is greater than the outer diameter length of the two opposing unlock sides 1214, wherein the sides of the two opposing lock sides 1213 are arc-shaped sides and the sides of the two opposing unlock sides 1214 are straight sides.Further, when the slope 1211 of the second assembly 12 enters the first retaining groove 1111 of the first assembly 11 with the unlocking side 1214, the unlocking side 1214 of the slope 1211 is not limited by the fixed portions 1131 of the elastic member 113. When the slope 1211 of the second assembly 12 enters the first retaining groove 1111 of the first assembly 11 with the locking side 1213, the locking side 1213 of the slope 1211 is affected by the fixed portions 1131 of the elastic part 113, wherein one side of the fixed portions 1131 of the elastic part 113 relative to the second assembly 12 has a first guide surface 1133 and one side of the two opposite locking sides 1213 relative to the first assembly 11 has second guide surfaces 1215. When the front side of the slope 1211 is inserted into the first retaining groove 1111, the second guide surface 1215 of the locking sides 1213 of the front side of the slope 1211 naturally contacts the first guide surface 1133 of the elastic member 113, so that the slope 1211 can press the elastic member 113 to allow the front side of the slope 1211 to enter the first retaining groove 1111. The second guide surface 1215 and the first guide surface 1133 help the front side of the slope 1211 to be inserted into the first retaining groove 1111, so that the second assembly 12 can be installed inside the first assembly 11. Thus, in the present embodiment, the slope 1211 of the second assembly 12 inserted into the first retaining groove 1111 is not limited, i.e., regardless of whether the locking side 1213 or the unlocking side 1214 of the slope 1211 corresponds to the fixed portions 1131 of the elastic member 113, they are not limited during assembly.In the present embodiment, the end face of the slope 1211 when inserted into the first retaining groove 1111 has a second combining piece 122, and the inside of the first retaining groove 1111 has a first combining piece 112. The first combining piece 112 has a through hole 1121. The second combining piece 122 has a pin 1221 that is a cylindrical body, and an end of the pin 1221 also has an arc surface. One end of the pin 1221 of the second combination piece 122 is inserted into the through hole 1121 of the first combination piece 112. The pin 1221 may also have other shapes that can be inserted into the through hole 1121. When the second assembly 12 is rotated relative to the first assembly 11, the arc surface of an end of the pin 1221 of the second combination piece 122 may rotate in the through hole 1121 of the first combination piece 112. The structure of the cylinder and the hole can effectively stabilize the first assembly 11 and the second assembly 12, so that the above-described turning operation is not prone to shake.To further elaborate, the first combination piece 112 may be a magnetic piece, and the second combination piece 122 may be either a magnetic piece or a magnetic mount, wherein the magnetic piece is made of different magnetic structures and the magnetic mount is made of a metal material that can be attracted by a magnet. The present embodiment does not limit the magnetic structural relationship between the first combination piece 112 and the second combination piece 122. The first combination piece 112 and the second combination piece 122 may be adapted as magnetic parts or magnetic attachments for mutual magnetic fixation according to the needs of the user. In the present embodiment, the first combining piece 112 and the second combining piece 122 may also fit into each other in addition to being magnetically fixed to each other, thereby enhancing the structural joining strength between the first combining piece 112 and the second combining piece 122. Moreover, the first combination piece 112 and the second combination piece 122 may not be limited to magnetic materials. Users may select the materials and structures of the first combination piece 112 and the second combination piece 122 according to their needs.In the present embodiment, referring to FIGS. 6 to 8, during the combination and fixation of the second assembly 12 and the first assembly 11, the slope 1211 of the second assembly 12 is inserted into the first retaining groove 1111 of the first assembly 11, and the second combination piece 122 of the second assembly 12 is mutually attracted and fixed with the first combination piece 112 of the first assembly 11. At this time, when the locking side 1213 on the end side of the slope 1211 corresponds to the fixed portions 1131 of the elastic member 113, the locking side 1213 is simultaneously restricted by the fixed portions 1131. Thus, the second assembly 12 and the first assembly 11 are locked together.Referring to FIGS. 3 to 4, during disassembly and separation of the second assembly 12 and the first assembly 11, the second assembly 12 is rotated relative to the first assembly 11 such that the unlocking side 1214 at the front side corresponds to the slope 1211 of the second assembly 12 with the fixed portions 1131 of the elastic member 113. The unlocking side 1214 is not restricted or affected by the fixed portions 1131. The slope 1211 of the second assembly 12 can freely enter and exit the first retaining groove 1111 of the first assembly 11. Further, when force is applied to remove the second assembly 12 and the force is larger than the magnetic force of the second combining piece 122 and the first combining piece 112 which attract each other, the second assembly 12 can be disassembled from the inside of the first assembly 11.To further effect, the first assembly 11 further includes a first rotating ring 115 disposed on the fixed plate 114. The first rotating ring 115 is located on the side of the opening of the passage 1141 that is far from the elastic member 113. The first rotating ring 115 has at least one latching nose 1151 on its surface. The second assembly 12 has a second rotating ring 123 disposed on the side of the slope 1211. The second rotating ring 123 has a plurality of depressions 1231 on its surface. The at least one latching nose 1151 of the first rotating ring 115 is inserted into one of the plurality of depressions 1231 of the second rotating ring 123. Thus, when the first assembly 11 is rotated relative to the second assembly 12, the detent 1151 of the first rotating ring 115 moves relative to the plurality of recesses 1231 of the second rotating ring 123. The latch 1151 that moves relative to the plurality of recesses 1231 will generate an upward and downward engagement feeling, so that the user can clearly feel the relative rotation angle of the first assembly 11 relative to the second assembly 12. In other words, this construction allows the combination pieces to rotate at any angle with substantial detents and positioning. Due to the magnetic attractive force, this will produce a special feel during the rotation at each step, so that the user can better recognize when the rotation is completed.In addition, referring to FIGS. 3 and 5, the first rotating ring 115 side has a first mark 1152 and the second rotating ring 123 side has a second mark 1232. When the first marker 1152 corresponds to the second marker 1232 during rotation, the first assembly 11 and the second assembly 12 are in either an unlocked or a locked state. This makes it convenient for the user to recognize the state of the structure of the quick release assembly 1.Based on the above description, the quick release assembly of the present invention is fixed by magnetic attraction by the first assembly and the second assembly; that is, by the magnetic force of the first body, the structure of the elastic member is forced apart to be combined. Even if non-magnetic materials are used, the structure of the elastic member can be forced apart by an external force. During the turning operation of the first assembly and the second assembly, the first assembly and the second assembly may change between locked and unlocked states. When the first assembly and the second assembly are rotated to the locked state, the first assembly and the second assembly are fixed not only by magnetic attraction but also by the inner structure. When the first assembly and the second assembly are rotated to the unlocked state, the first assembly and the second assembly are fixed only by the magnetic attractive force. By applying a force larger than the magnetic attraction, the second assembly can be disassembled from the first assembly, and thus the construction of the present invention is suitable for quick disassembly and quick assembly.The foregoing description of the preferred embodiments of the invention has been presented for purposes of illustration and description.
