Description

Technical Field

[0001] This invention relates to the field of quick-release structure technology, and in particular to a housing structure and an assembled product using the housing structure. Background Technology

[0002] In related technologies, the shell structure generally adopts welding or assembly methods depending on different needs. The outer shell assembly usually uses screws or clips for fixation. Although clip fixation is aesthetically pleasing, it requires considerable pressing force during assembly to ensure the clips are in place, and it is difficult to disassemble, as the clips are hard to separate. Screw fixation generally requires multiple screws, the assembly steps are cumbersome, and the screw positions are clearly visible. Existing assembly methods cannot achieve one-step disassembly, thus failing to enable quick disassembly. Summary of the Invention

[0003] The main objective of this invention is to provide a housing structure and assembled product, which aims to provide a housing structure that enables rapid disassembly. This housing structure not only allows for one-step disassembly, but also makes the disassembly process simple and convenient.

[0004] To achieve the above objectives, the present invention proposes a shell structure, the shell structure comprising:

[0023] And / or, the rotating cylinder is provided with a notch communicating with the rotating cavity and a fastening member provided in the notch, and the outer wall of the rotating shaft is provided with a locking platform. When the rotating shaft moves and disengages along the axial direction of the rotating cavity, the fastening member engages with the locking platform.

[0024] In one embodiment, the mounting part is fixedly connected to the knob by bolts;

[0025] And / or, the support part is provided with a limiting groove on the side opposite to the rotating shaft, and the elastic part is limited to the limiting groove;

[0026] And / or, the elastic part includes a plurality of elastic parts, which are spaced apart along the periphery of the mounting part, and each elastic part is provided with a locking part at one end away from the mounting part, and the second housing is provided with a shrinkage groove corresponding to each locking part;

[0027] And / or, the elastic part includes a first straight section, a vertical section and a second straight section connected to each other. The first straight section is connected to the mounting part and abuts against and limits the side of the support part opposite to the rotating shaft.

The first straight section and the second straight section are located in different planes.

[0028] And / or, the surface of the rotating shaft facing away from the support is provided with a groove.

[0029] In one embodiment, the locking part includes a first arc segment and a second arc segment connected to each other, the first arc segment being connected to the elastic part, and the end of the second arc segment away from the first arc segment forming a free end;

[0030] In the assembled state, the projection of the free end onto the second housing is within the projection range of the second housing, while a portion of the second arc segment is outside the projection range of the second housing.

[0031] In the disassembled state, the projection of the second arc segment onto the second housing is always within the projection range of the second housing.

[0032] In one embodiment, the second housing is further provided with a limiting protrusion spaced apart from the shrink groove; wherein, when the knob drives the elastic member to rotate relative to the second housing, the locking part moves between the limiting protrusion and the shrink groove;

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0053] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0056] Currently, shell structures are generally assembled using welding or assembly methods depending on the specific needs. The outer shell is typically fixed using screws or clips. While clip-on fixing is aesthetically pleasing, it requires significant pressure during assembly to ensure the clips are firmly in place, making disassembly difficult. Screw fixing generally requires multiple screws, making assembly cumbersome, and the screw positions are clearly visible. Existing assembly methods cannot achieve a one-step disassembly, hindering rapid disassembly.

[0057] Based on the above concepts and problems, this invention proposes a housing structure 100. It is understood that the housing structure 100 can be applied to various products, equipment, or structures requiring housing assembly. Optionally, the housing structure 100 is applied to assembled products, which can be electronic products or other products, and this is not limited thereto.

[0058] Please refer to the reference. Figures 1 to 10 As shown, in this embodiment of the invention, the housing structure 100 includes a first housing 1, a second housing 2, and a locking assembly 3. The first housing 1 is provided with a mounting hole 11, and the second housing 2 is detachably disposed at the mounting hole 11. The second housing 2 is provided with a shrinkage groove 21. The locking assembly 3 is rotatably connected to the second housing 2 and is provided with a locking part 321. The locking assembly 3 rotates relative to the second housing 2 so that the housing structure 100 has an assembled state and a disassembled state. In the assembled state, the second housing 2 is installed at the mounting hole 11, and the locking part 321 is engaged with the first housing 1. In the disassembled state, the locking part 321 shrinks and engages with the shrinkage groove 21 so that the second housing 2 is disengaged from the mounting hole 11.

[0059] In this embodiment, the first housing 1 and the second housing 2 of the housing structure 100 can be the outer shell structure of the product, used to protect, install, support, or fix the internal components or electronic components of the product, etc., and are not limited here. It is understood that the first housing 1 and the second housing 2 of the housing structure 100 can enclose a cavity 13 or a mounting cavity, etc., and are not limited here.

[0060] It is understood that the first housing 1 and the second housing 2 can be metal parts made of metal, plastic parts made of plastic, or integrally injection molded metal and plastic parts, etc., and are not limited here. In this embodiment, as... Figure 1 , Figure 3 and Figure 5 As shown, the first housing 1 has a cavity 13, and the first housing 1 is provided with a mounting hole 11 communicating with the cavity 13. The mounting hole 11 can be a partially open hole or a structure with an opening on one side, etc., and is not limited here.

[0061] In this embodiment, the shape and outline of the mounting hole 11 of the first housing 1 can be circular, elliptical, triangular, square, or other polygonal or irregular structures, etc., and is not limited here. To facilitate the assembly of the second housing 2 and improve adaptability and sealing, the shape and outline of the mounting hole 11 may optionally be similar to the outer outline of the second housing 2. It is understood that when the second housing 2 is installed at the mounting hole 11 of the first housing 1, it can completely cover or close the mounting hole 11, and is not limited here.

[0062] Of course, in order to further improve the sealing performance, sealing strips or sealant may also be provided at the second housing 2 and the mounting hole 11, which is not limited here.

[0063] In this embodiment, the second housing 2 is detachably disposed at the mounting hole 11, meaning that the second housing 2 can be installed at the mounting hole 11 and can also be disassembled from the mounting hole 11. To enable the second housing 2 to be assembled and fixed at the mounting hole 11, the second housing 2 is provided with a shrinkage groove 21. A locking assembly 3 is provided on the second housing 2, allowing the locking assembly 3 to be rotatably connected to the second housing 2. The locking assembly 3 is provided with a locking part 321. Thus, by rotating the locking assembly 3 relative to the second housing 2, the second housing 2 can be locked to the mounting hole 11 of the first housing 1 or released from the mounting hole 11 for disassembly.

[0064] Understandably, the locking assembly 3 rotates relative to the second housing 2, causing the housing structure 100 to have both an assembled state where the second housing 2 is installed at the mounting hole 11 of the first housing 1 and a disassembled state where the second housing 2 is removed from the mounting hole 11 of the first housing 1. In this embodiment, in the assembled state, the second housing 2 is installed at the mounting hole 11, and the locking part 321 of the locking assembly 3 engages with the first housing 1, so that the second housing 2 is detachably connected to the first housing 1; in the disassembled state, the locking part 321 of the locking assembly 3 retracts and engages with the retraction groove 21, at which point the second housing 2 is released from the first housing 1, thereby facilitating the disassembly of the second housing 2 from the mounting hole 11.

[0065] In this embodiment, the rotation of the locking component 3 relative to the second housing 2 can be manually operated. Of course, in other embodiments, the rotation of the locking component 3 relative to the second housing 2 can also be electrically controlled, and this is not limited here.

[0066] The housing structure 100 of the present invention provides a mounting hole 11 in the first housing 1, which facilitates the detachable mounting of the second housing 2 at the mounting hole 11, enabling the assembly and disassembly of the first housing 1 and the second housing 2 of the housing structure 100. Simultaneously, by providing a shrinkage groove 21 and a locking component 3 in the second housing 2, the locking component 3 is rotatably connected to the second housing 2, and the locking component 3 has a locking part 321. Thus, by rotating the locking component 3 relative to the second housing 2, the second housing 2 is mounted at the mounting hole 11 of the first housing 1, allowing the housing structure 100 to have both an assembled state and a disassembled state. In the assembled state, the second housing 2 is mounted at the mounting hole 11 and engages with the first housing 1 using the locking part 321, thereby achieving quick assembly and connection of the first housing 1 and the second housing 2 of the housing structure 100. In the disassembled state, the locking part 321 shrinks and engages with the shrinkage groove 21 of the second housing 2, allowing the second housing 2 to easily disengage from the mounting hole 11 of the first housing 1, thereby achieving quick disassembly. Understandably, the housing structure 100 of this application achieves rapid assembly and disassembly of the first housing 1 and the second housing 2 by utilizing the locking assembly 3 to rotate relative to the second housing 2. This not only enables one-step disassembly and rapid disassembly, but also makes the disassembly process simple and convenient.

[0067] In one embodiment, the first housing 1 is provided with a locking groove 12 near the mounting hole 11; in the assembled state, the locking part 321 is engaged with the locking groove 12.

[0068] In this embodiment, as Figure 1 , Figures 3 to 5As shown, by providing a locking groove 12 in the cavity 13 of the first housing 1 or on the wall of the mounting hole 11, when the locking assembly 3 rotates relative to the second housing 2, the locking part 321 is engaged in the locking groove 12, thereby locking the second housing 2 at the mounting hole 12 of the first housing 1 by means of the locking part 321.

[0069] To facilitate the locking part 321 engaging with the locking groove 12, the locking groove 12 may optionally be located adjacent to the mounting hole 11, that is, the locking groove 12 is located within the cavity 13 of the first housing 1. In this embodiment, the opening of the locking groove 12 faces the mounting hole 11. It can be understood that, to facilitate the locking part 321 entering the locking groove 12, the opening of the locking groove 12 extends through one side of the groove wall.

[0070] In this embodiment, an L-shaped boss protrudes from the inner wall of the cavity 13 of the first housing 1, and the L-shaped boss and the inner wall of the cavity 13 enclose to form a locking groove 12. In order to further engage the limiting locking part 321, a baffle or baffle structure is provided at the end of the L-shaped boss away from the inner wall of the cavity 13, so that the baffle or baffle structure, the L-shaped boss and the inner wall of the cavity 13 enclose to form the locking groove 12, which is not limited here.

[0071] In one embodiment, the locking assembly 3 has a plurality of locking parts 321, the second housing 2 has a plurality of retraction slots 21, and the first housing 1 has a plurality of locking slots 12. Optionally, the number of locking parts 321, the number of retraction slots 21, and the number of locking slots 12 correspond one-to-one. In this embodiment, the retraction slots 21 may be located at the edge or periphery of the second housing 2, and are not limited thereto.

[0072] In one embodiment, the locking assembly 3 includes a knob 31 and an elastic member 32. The knob 31 is rotatably connected to the second housing 2. The elastic member 32 includes a mounting portion 322 and an elastic portion 323 connected to the mounting portion 322. The mounting portion 322 is connected to the knob 31. A locking portion 321 is provided at one end of the elastic portion 323 away from the mounting portion 322. The knob 31 drives the elastic member 32 to rotate relative to the second housing 2, so that the locking portion 321 engages with the first housing 1 or engages in the shrinkage groove 21.

[0073] In this embodiment, as Figure 1 , Figures 3 to 9 As shown, the knob 31 of the locking assembly 3 is fixedly connected to the elastic element 32. Optionally, the knob 31 and the elastic element 32 can be fixedly connected by fasteners or bolts, which is not limited here. It is understood that the knob 31 can be rotatably connected to the second housing 2 via a hole shaft. Of course, the knob 31 can also be rotatably connected to the second housing 2 via other rotatable connection methods, which is not limited here.

[0074] Understandably, by configuring the elastic element 32 as a mounting part 322, an elastic part 323, and a locking part 321, and using the mounting part 322 to fix it to the knob part 31 via bolts 34, the stability of the connection between the elastic element 32 and the knob part 31 can be improved. In this embodiment, the elastic part 323 can drive the locking part 321 to contract and deform, so that when the knob part 31 drives the elastic element 32 to rotate relative to the second housing 2, the locking part 321 is engaged with the locking groove 12 of the first housing 1 or engaged in the contraction groove 21 under the elastic action of the elastic part 323.

[0075] Optionally, the elastic element 32 can be made of plastic or metal. The elastic element 32 can be a plastic elastic element or a metal elastic element, etc., which can ensure the strength of the elastic element 32 while having the ability to deform elastically. There is no limitation here.

[0076] In order to further limit and fix the elastic element 32, in this embodiment, the knob 31 is provided with a limiting groove 3122 corresponding to the elastic part 323 of the elastic element 32. The elastic part 323 is limited in the limiting groove 3122. This ensures that when the knob 31 rotates relative to the second housing 2, it can drive the elastic element 32 to rotate together relative to the second housing 2.

[0077] Optionally, the elastic element 32 has multiple elastic portions 323, which are spaced apart along the periphery of the mounting portion 322. In this case, each elastic portion 323 has a locking portion 321 at one end away from the mounting portion 322. In this embodiment, the second housing 2 has a shrinkage groove 21 corresponding to each locking portion 321, and the first housing 1 has a locking groove 12 corresponding to each locking portion 321.

[0078] In one embodiment, the second housing 2 is provided with a rotating cylinder 22, which forms a rotating cavity 221, and a portion of the knob 31 is rotatably disposed in the rotating cavity 221; the locking assembly 3 also includes an elastic connector 33, one end of which is connected to the knob 31, and the other end of which is connected to the second housing 2.

[0079] In this embodiment, as Figure 1 , Figures 3 to 10 As shown, the second housing 2 has a first surface and a second surface that are opposite to each other. When the second housing 2 is installed in the mounting hole 11 of the first housing 1, the first surface of the second housing 2 faces the cavity 13. The second surface of the second housing 2 can optionally be flush with the outer wall surface of the first housing 1, which can improve the appearance of the housing structure 100.

[0080] Understandably, the first surface of the second housing 2 is provided with a rotating cylinder 22, and a shrinkage groove 21 is provided on the first surface of the second housing 2. Optionally, the shrinkage groove 21 is located at the edge or periphery of the first surface of the second housing 2. The rotating cylinder 22 forms a rotating cavity 221, which penetrates the first surface and the second surface of the second housing 2, so that a portion of the knob 31 extends into the rotating cavity 221 and can rotate relative to the rotating cylinder 22.

[0081] In order to connect and fix the knob 31 of the locking assembly 3 to the second housing 2 while ensuring that the knob 31 can rotate relative to the second housing 2, in this embodiment, an elastic connector 33 is provided to connect the knob 31 to the second housing 2. This allows the elasticity of the elastic connector 33 to connect the knob 31 to the second housing 2 without affecting the rotation of the knob 31 relative to the second housing 2.

[0082] In one embodiment, the knob 31 includes a rotating shaft 311 and a support portion 312. One end of the rotating shaft 311 is rotatably disposed in the rotating cavity 221, and the support portion 312 is disposed at the other end of the rotating shaft 311. The side of the support portion 312 facing away from the rotating shaft 311 is connected to the mounting portion 322, and one end of the elastic connector 33 is connected to the side of the support portion 312 facing away from the mounting portion 322.

[0083] In this embodiment, as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the rotation shaft 311 of the knob 31 can optionally be cylindrical, and the support portion 312 can optionally be plate-shaped or disc-shaped. The support portion 312 of the knob 31 is located at one end of the rotation shaft 311. Optionally, the rotation shaft 311 and the support portion 312 are integrally formed, such as by integral injection molding or integral machining, etc., which is not limited here.

[0084] Understandably, the support portion 312 of the knob 31 is connected to the mounting portion 322 of the elastic member 32. In this embodiment, the support portion 312 is provided with a screw hole, and the mounting portion 322 is provided with a through hole. Bolts 34 pass through the through hole in sequence and are installed in the screw hole to achieve a tight connection between the mounting portion 322 and the support portion 312. Optionally, the support portion 312 is provided in the shape of a disc or a circular plate, and the diameter of the support portion 312 is larger than the diameter of the rotating shaft 311.

[0085] In this embodiment, one end of the elastic connector 33 is connected to the side of the support portion 312 facing away from the mounting portion 322, and the other end of the elastic connector 33 is connected to the first surface of the second housing 2. Optionally, the elastic connector 33 is a telescopic spring or a tension spring.

[0086] To facilitate the connection and fixation of the elastic connector 33, in one embodiment, one of the second housing 2 and the support 312 is provided with a first slot 23, and the other is provided with a second slot 3121. The two ends of the elastic connector 33 are respectively engaged in the first slot 23 and the second slot 3121.

[0087] In this embodiment, as Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, the first surface of the second housing 2 is provided with a first slot 23, and the support part 312 of the knob 31 is provided with a second slot 3121. Optionally, the two ends of the elastic connector 33 are respectively engaged in the first slot 23 and the second slot 3121. This facilitates the disassembly and assembly of the elastic connector 33, while ensuring that the elastic connector 33 does not affect the rotation of the knob 31 relative to the second housing 2.

[0088] Optionally, the first surface of the second housing 2 is provided with a plurality of first slots 23, which are arranged around the rotating cylinder 22 and spaced apart from the outer wall of the rotating cylinder 22. The support portion 312 of the knob 31 is provided with a plurality of second slots 3121, which are arranged around the rotating shaft 311 and spaced apart from the outer wall of the rotating shaft 311.

[0089] In one implementation, such as Figure 3 and Figure 10 As shown, the elastic connector 33 can be selected as one, and the elastic connector 33 has a hollow cavity 331, within which the rotating cylinder 22 is located. It can be understood that the elastic connector 33 is sleeved on the outer wall of the rotating cylinder 22.

[0090] Optionally, the cross-sectional area at both ends of the elastic connector 33 is larger than the cross-sectional area at the center of the elastic connector 33. This allows the two ends of the elastic connector 33 to be easily engaged in the first slot 23 and the second slot 3121.

[0091] In this embodiment, when the rotating shaft 311 of the knob 31 is inserted into the rotating cavity 221 of the rotating cylinder 22, the elastic connector 33 is stretched. Under the action of the spring tension of the elastic connector 33, the rotating shaft 311 of the knob 31 is inserted into the rotating cavity 221 of the rotating cylinder 22, and the locking platform 3111 of the rotating shaft 311 slides into the locking member 224, so that it cannot be dislodged backward under the limiting action of the locking member 224. At the same time, the support part 312 of the knob 31 abuts against the end face of the rotating cylinder 22, achieving the limiting effect.

[0092] Understandably, when no external force is applied, there is a certain distance between the buckle 224 and the locking platform 3111. This can prevent the knob 31 from having a large friction when rotating, and can also prevent the rotating shaft 311 of the knob 31 from disengaging from the rotating cavity 221 of the rotating cylinder 22 when an external force is applied.

[0093] In another embodiment, the elastic connectors 33 include a plurality of elastic connectors 33 arranged around the rotating cylinder 22. It is understood that the plurality of elastic connectors 33 are spaced apart and arranged around the rotating cylinder 22. In this embodiment, the second housing 2 and the support portion 312 are respectively provided with a first slot 23 and a second slot 3121 corresponding to each elastic connector 33.

[0094] Of course, in order to facilitate the disassembly and assembly of the elastic connector 33, and to ensure that the elastic connector 33 does not affect the rotation of the knob 31 relative to the second housing 2, any method that can achieve the connection between the elastic connector 33 and the second housing 2 and the support part 312 is acceptable and is not limited here.

[0095] In one embodiment, the rotating cylinder 22 is provided with a notch 223 communicating with the rotating cavity 221 and a fastener 224 provided in the notch 223. The outer wall of the rotating shaft 311 is provided with a locking platform 3111. When the rotating shaft 311 moves along the axial direction of the rotating cavity 221 and disengages, the fastener 224 engages with the locking platform 3111.

[0096] In this embodiment, as Figure 3 , Figure 4 , Figure 6 As shown, by providing a notch 223 in the rotating cylinder 22 of the second housing 2 and a snap fastener 224 in the notch 223, and a snap-fit ​​platform 3111 on the rotating shaft 311 of the knob 31, when the rotating shaft 311 is pushed and moved along the axial direction of the rotating cavity 221 by an external force and disengages, the snap fastener 224 can be snapped into the snap-fit ​​platform 3111, thereby preventing the rotating shaft 311 of the knob 31 from disengaging from the rotating cavity 221 of the rotating cylinder 22.

[0097] In one implementation, such as Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a groove 3112 is provided on the surface of the rotating shaft 311 facing away from the support part 312. It can be understood that by providing a groove 3112 on the rotating shaft 311 of the knob 31, it is convenient for the user to drive the knob 31 to rotate through the groove 3112 via an external component, thereby improving convenience.

[0098] Optionally, the support portion 312 of the knob 31 abuts against the end face of the rotating cylinder 22 away from the first surface of the second housing 2.

[0099] In one embodiment, the support portion 312 of the knob 31 has a limiting groove 3122 on the side opposite to the rotation shaft 311, and the elastic portion 323 is limited within the limiting groove 3122. It can be understood that the limiting groove 3122 can be used to further limit the elastic member 32, so that the elastic member 32 rotates relative to the second housing 2 as the knob 31 rotates.

[0100] In one embodiment, the elastic part 323 includes a first straight section 3231, a vertical section 3232, and a second straight section 3233 connected to each other. The first straight section 3231 is connected to the mounting part 322 and abuts against the side of the support part 312 opposite to the rotation shaft 311 for limiting. The end of the second straight section 3233 away from the vertical section 3232 is connected to the locking part 321 and abuts against the surface of the second housing 2. The first straight section 3231 and the second straight section 3233 are located in different planes.

[0101] In this embodiment, as Figure 1 , Figure 3 , Figure 9 As shown, the first straight section 3231 and the second straight section 3233 of the elastic part 323 can optionally be arranged in parallel. The first straight section 3231 is connected to the mounting part 322, and the first straight section 3231 and the mounting part 322 are located on the same plane. Both of them abut against and limit the side of the support part 312 opposite to the rotation shaft 311. The vertical section 3232 allows the first straight section 3231 and the second straight section 3233 to be located on different planes, which facilitates the second straight section 3233 to abut against the first surface of the second housing 2.

[0102] Optionally, the locking portion 321 is connected to the end of the second straight section 3233 away from the vertical section 3232. In this embodiment, the elastic portion 323 extends from the mounting portion 322 toward the edge of the second housing 2. In this embodiment, the locking portion 321 may optionally be located on the same plane as the second straight section 3233.

[0103] In one embodiment, the locking part 321 includes a first arc segment 3211 and a second arc segment 3212 connected to each other. The first arc segment 3211 is connected to the elastic part 323, and the end of the second arc segment 3212 away from the first arc segment 3211 forms a free end 3213. In the assembled state, the projection of the free end 3213 onto the second housing 2 is within the projection range of the second housing 2, and a portion of the projection of the second arc segment 3212 onto the second housing 2 is outside the projection range of the second housing 2. In the disassembled state, the projections of the second arc segment 3212 onto the second housing 2 are all within the projection range of the second housing 2.

[0104] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 9As shown, by setting the locking part 321 into an arc-shaped structure, and by setting the locking part 321 into a first arc segment 3211 and a second arc segment 3212 connected together, the arc shape of the locking part 321 can be used to conveniently confine it within the shrinkage groove 21 and the locking groove 12. It can be understood that by forming a free end 3213 at the end of the second arc segment 3212 away from the first arc segment 3211, the free end 3213 can be used to guide the locking part 321 when it is confined within the shrinkage groove 21.

[0105] Understandably, when the elastic element 32 is in its normal state, i.e., not retracted within the shrinkage groove 21, the distance from the free end 3213 to the rotation center of the knob 31 is less than the distance from at least a portion of the second arc segment 3212 to the rotation center of the knob 31. In this embodiment, the distance from the free end 3213 to the rotation center of the knob 31 is less than the distance from the edge of the second housing 2 to the rotation center of the knob 31, and the distance from at least a portion of the second arc segment 3212 to the rotation center of the knob 31 is greater than the distance from the edge of the second housing 2 to the rotation center of the knob 31.

[0106] Optionally, in the assembled state, the projection of the free end 3213 onto the second housing 2 is within the projection range of the second housing 2, while the projection of a portion of the second arc segment 3212 onto the second housing 2 is outside the projection range of the second housing 2. In the disassembled state, the projections of the second arc segment 3212 onto the second housing 2 are all within the projection range of the second housing 2. This ensures that the second housing 2 is locked to the first housing 1 by the locking part 321 of the locking assembly 3.

[0107] In this embodiment, the second arc segment 3212 is a convex arc with its center located on the side of the second arc segment 3212 facing the mounting portion 322.

[0108] In one embodiment, the second housing 2 is further provided with a limiting protrusion 24 spaced apart from the shrink groove 21; wherein, when the knob 31 drives the elastic member 32 to rotate relative to the second housing 2, the locking part 321 moves between the limiting protrusion 24 and the shrink groove 21.

[0109] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, by providing a limiting protrusion 24 on the first surface of the second housing 2, the limiting protrusion 24 can stop and phase the rotation of the elastic member 32 relative to the second housing 2, thus avoiding excessive rotation.

[0110] Optionally, the retraction slot 21 and the limiting protrusion 24 are disposed adjacent to the edge of the second housing 2. In this embodiment, there are multiple limiting protrusions 24, each corresponding to a retraction slot 21.

[0111] In this application, the first housing 1 and the second housing 2 of the housing structure 100 are quickly fixed or disassembled by the locking assembly 3. When assembling or disassembling the first housing 1 and the second housing 2, only one point needs to be controlled, namely the knob 31 of the locking assembly 3. There are no multiple fixing points that need to be controlled. The quick fixing or disassembly can be achieved by simply rotating the knob 31, which is convenient and fast, and the overall appearance is maintained to a certain extent.

[0112] Understandably, the housing structure 100 of this application does not significantly alter the overall appearance of the product, and is simple to operate, requiring no complex steps or significant force, making it easy to assemble and disassemble. It should be noted that the housing structure 100 can quickly assemble common outer shells and housings together, and can also be quickly disassembled.

[0113] In this embodiment, the elastic element 32 of the locking assembly 3 is fixed to the knob 31 by bolts 34 or screws. Under the spring tension of the elastic connector 33, the knob 31 is pulled together with the second housing 2 to form a housing assembly. The rotation of the knob 31 drives the rotation of the elastic element 32, thereby screwing the locking portion 321 at the end of the elastic element 32 into the locking groove 12 of the first housing 1 for fixation. It can be understood that by rotating the knob 31 to quickly screw the locking portion 321 at the end of the elastic element 32 into or out of the locking groove 12 of the first housing 1 and the retraction groove 21 of the second housing 2, the second housing 2 can be quickly fixed or disassembled.

[0114] Understandably, before installing the second housing 2 of the housing structure 100, a flat-head tool, such as a flat-head screwdriver, is used to insert into the groove 3112 on the outer surface of the knob 31. The knob 31 is rotated, and the elastic element 32 rotates with the knob 31. The locking part 321 at the end of the elastic element 32 is arc-shaped and has a guiding function. When rotating, the locking part 321 of the elastic element 32 can be rotated into the shrinkage groove 21 of the second housing 2, and the locking part 321 of the elastic element 32 is retracted into the shrinkage groove 21.

[0115] When the second housing 2 of the housing structure 100 is installed on the first housing 1, the assembled second housing 2 and the locking assembly 3 form the outer shell assembly, which is then placed into the corresponding mounting hole 11 of the first housing 1. The knob 31 is rotated in the reverse direction, causing the locking part 321 of the elastic element 32 to unscrew from the contraction groove 21 of the second housing 2. At this point, the locking part 321 of the elastic element 32 is released. Continuing to rotate the knob 31, the locking part 321 is screwed into the locking groove 12 of the first housing 1, thus fixing the second housing 2 and the first housing 1 together. It is understood that the limiting protrusion 24 of the second housing 2 acts as a barrier to prevent the locking part 321 of the elastic element 32 from excessively rotating and unscrewing from the locking groove 12 of the first housing 1 during this process, thus providing a limiting function.

[0116] When the second housing 2 of the housing structure 100 is disassembled from the first housing 1, the knob 31 is rotated in the opposite direction again, causing the locking part 321 of the elastic member 32 to be screwed out of the locking groove 12 of the first housing 1. Then it is screwed into the shrinking groove 21 of the second housing 2 to reach the state before installation, and the second housing 2 can then be disassembled and removed.

[0117] It should be noted that after assembling the knob 31, the second housing 2, etc., into the assembly as described above, the rotation of the knob 31 drives the rotation of the elastic element 32, thereby causing the locking part 321 at the end of the elastic element 32 to be screwed into or out of the contraction groove 21 of the second housing 2 and the locking groove 12 of the first housing 1, thus achieving fixation and disassembly. Since the elastic element 32 has multiple locking parts 321 at its ends, the second housing 2 and the first housing 1 can be fixed at multiple points during fixation to meet the required strength. The second housing 2 and the first housing 1 are fixed by the engagement of the elastic element 32. Thus, by controlling the knob 31, the internal engagement structure is controlled, achieving rapid fixation and disassembly without affecting the strength of the fixation.

[0118] It is understandable that the second housing 1 and the first housing 1 are not limited to a circular fit. Since the rotation is performed by the internal structure of the second housing 2, whether the second housing 2 itself rotates or not does not affect the assembly and disassembly process. Therefore, the shapes of the second housing 2 and the first housing 1 can be other regular or irregular shapes.

[0119] Compared with existing products, the housing structure 100 of this application achieves the assembly and disassembly of the second housing 2 and the first housing 1 by controlling only one knob 31. It has advantages such as speed and simple appearance. This structure is convenient for users to operate, is quick and easy, and is not prone to misoperation.

[0120] The present invention also proposes an assembled product, which includes the aforementioned housing structure 100. The specific structure of the housing structure 100 is as described in the foregoing embodiments. Since this assembled product adopts all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be repeated here.

[0121] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
