[0013] In some embodiments, the positioning station is provided with double-sided adhesive tape, which is suitable for bonding the component to the first housing; and the double-sided adhesive tape has weak adhesion on one side of the first housing, which is suitable for following the movement of the component driven by the stopper.

[0014] In some embodiments, the double-sided adhesive tape is a copper foil double-sided tape.

[0015] In some embodiments, the first limiting member includes a first clamping portion and a first connecting portion arranged at an angle, and the first connecting portion is used to connect the first clamping portion to one side of the first housing facing the second housing; and / or, the first limiting member includes a first clamping portion arranged on the inner side wall of the first housing.

[0016] The second limiting member includes a second clamping portion and a second connecting portion arranged at an angle, and the second connecting portion is used to connect the second clamping portion to one side of the second housing facing the first housing.

[0017] When the first housing is in the first position, the second clamping portion is located on the side of the first clamping portion away from the second housing, and the first clamping portion and the second clamping portion are clamped together; when the first housing is in the second position, the first clamping portion and the second clamping portion are separated.

[0018] In some embodiments, the first housing has opposite first and second sides along the sliding direction of the second housing.

[0019] The first connecting portion is arranged at one end of the first clamping portion close to the second side, and the second connecting portion is arranged at one end of the second clamping portion close to the first side; and / or,

[0020] One end of the first clamping portion close to the second side and away from the second housing is provided with a first guide surface, and one end of the second clamping portion close to the first side and away from the first housing is provided with a second guide surface.

[0021] In some embodiments, the first housing sidewall has a first fastening hole, the second housing has a fastening block, and the fastening block has a second fastening hole;

[0024] This application also provides an electronic device, including: an element and a housing assembly provided in any of the above embodiments.

[0025] The technical advantages of this application are as follows:

[0026] 1. In this application, the first housing and the second housing can slide together, supplemented by the limiting cooperation of the first limiting member and the second limiting member between them. The user only needs to slide the first housing and / or the second housing to realize the disassembly and assembly between the first housing and the second housing. The operation is convenient and quick, which solves the problem of complex process and low efficiency in the production assembly or after-sales disassembly of existing electronic equipment.

[0027] 2. In this application, the second housing is provided with a baffle. During production and assembly, the second housing slides relative to the first housing, and the baffle can drive the component to the preset installation position.

[0028] 3. In this application, during the initial production assembly stage, the components are pre-fixed by attaching them to the positioning station of the first housing using double-sided adhesive. This double-sided adhesive uses copper foil with adhesive on both sides, possessing weak adhesion and a certain degree of rigidity, which does not affect the subsequent sliding of the components. This allows the components to move stably to the preset installation position under the action of the baffle, achieving precise positioning of the internal components. Furthermore, the copper foil double-sided adhesive also enables electrical conductivity between the components and the first housing, solving the problem of connecting the movable internal components to the bottom housing.

[0046] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0047] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0048] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0049] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0050] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this application are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, these directional indications also change accordingly.

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] According to a specific embodiment provided in this application, see [link to specific embodiment]. Figure 1 and Figure 2 A housing assembly is disclosed, suitable for electronic products where components need to be installed or disassembled during production or after-sales service, such as cash registers. The housing assembly includes a first housing 100 and a second housing 200. The first housing 100 has an open cavity 110 suitable for accommodating a component 300. The second housing 200 covers the opening of the first housing 100 and is slidably positioned in a first position and a second position relative to the opening of the first housing 100. Furthermore, the first housing 100 includes a first limiting member 120, and the second housing 200 includes a second limiting member 210 that matches the first limiting member 120.

[0054] When the second housing 200 is in the first position relative to the first housing 100, the first limiting member 120 and the second limiting member 210 engage in a limiting cooperation, which can prevent the second housing 200 from leaving the opening of the first housing 100; when the second housing 200 is in the second position relative to the first housing 100, the first limiting member 120 and the second limiting member 210 disengage, and the user can remove the second housing 200 from the first housing 100.

[0055] In this embodiment, the first housing 100 and the second housing 200 adopt a sliding fit, supplemented by the limiting fit of the first limiting member 120 and the second limiting member 210. The user only needs to slide the first housing 100 and / or the second housing 200 to realize the disassembly and assembly between the first housing 100 and the second housing 200. The operation is convenient and quick, which solves the problem of complex process and low efficiency in the production assembly or after-sales disassembly of existing electronic devices.

[0056] For example, the first limiting member 120 and the second limiting member 210 can adopt a sliding groove and a slider structure. For instance, the inner wall of the first housing 100 is provided with a slider, and the second housing 200 is provided with an axially extending sliding groove. When the user slides the first housing 100 and / or the second housing 200 to make the second housing 200 relative to the first housing 100 in a first position, the slider slides in the sliding groove, and the first housing 100 and the second housing 200 are connected. Conversely, if the user slides the first housing 100 and / or the second housing 200 to make the slider disengage from the sliding groove, the first housing 100 and the second housing 200 can be separated, making disassembly and assembly convenient.

[0057] Of course, for example, see Figures 2 to 5 and Figure 7 , Figure 8The first limiting member 120 and the second limiting member 210 may also adopt a snap-fit ​​structure. Specifically, the first limiting member 120 includes a first engaging portion 121 and a first connecting portion 122 arranged at an angle, the first connecting portion 122 being used to connect the first engaging portion 121 to the side of the first housing 100 facing the second housing 200. Conversely, the second limiting member 210 includes a second engaging portion 211 and a second connecting portion 212 arranged at an angle, the second connecting portion 212 being used to connect the second engaging portion 211 to the side of the second housing 200 facing the first housing 100. When the user slides the first housing 100 and / or the second housing 200 to a first position relative to the first housing 100, the second engaging part 211 is located on the side of the first engaging part 121 away from the second housing 200 and can engage with the first engaging part 121, thereby connecting the first housing 100 and the second housing 200; when the user slides the first housing 100 and / or the second housing 200 again to a second position relative to the first housing 100, the first engaging part 121 and the second engaging part 211 disengage, thereby separating the first housing 100 and the second housing 200, making disassembly and assembly convenient.

[0058] In this embodiment, the first limiting member 120 is provided on the side of the first housing 100 facing the second housing 200. In actual production, some of the first limiting members 120 can also be directly provided on the inner side wall of the first housing 100. In this case, the first limiting member 120 includes the first engaging part 121, which eliminates the need for the first connecting part 122, resulting in less material consumption and lower production cost.

[0059] Specifically, taking a rectangular first housing 100 as an example, it has opposing first sides 140 and second sides 150 along the sliding direction of the second housing 200, and opposing third sides 170 and fourth sides 180 are connected between the first sides 140 and second sides 150. For ease of description, let the direction of the second housing 200 from the second position to the first position be the direction of the first side 140 to the second side 150 of the first housing 100. At this time, the inner sidewalls of the second side 150, third side 170, and fourth side 180 of the first housing 100 can all be directly provided with first engaging portions 121. Correspondingly, the side of the first housing 100 facing the second housing 200 near the first side 140 is provided with a first connecting portion 122 and a first engaging portion 121. In this embodiment, by providing first limiting members 120 on all four sides (first side 140, second side 150, third side 170, and fourth side 180) inside the first housing 100, a stable connection between the first housing 100 and the second housing 200 is achieved.

[0060] Preferably, the first connecting part 122 is located at the end of the first engaging part 121 near the second side 150, and the second connecting part is located at the end of the second engaging part 211 near the first side 140. In this case, the first connecting part 122 and the second connecting part not only connect the first engaging part 121 and the second engaging part 211, but also serve as a limit and indicator. Specifically, during assembly, when the first engaging part 121 abuts against the second connecting part, and when the second engaging part 211 abuts against the first connecting part 122, the user can feel resistance, thus reminding the user that the second housing 200 has reached the first position, and that the first housing 100 and the second housing 200 are assembled with high precision.

[0061] Furthermore, the first engaging portion 121 has a first guide surface 123 on the end near the second side 150 and on the side away from the second housing 200, and the second engaging portion 211 has a second guide surface 213 on the end near the first side 140 and on the side away from the first housing 100. The first guide surface 123 and the second guide surface 213 can be convex arc surfaces or parallel inclined surfaces, which helps guide the first engaging portion 121 and the second engaging portion 211 to engage with each other, reducing collision and wear between them.

[0062] In a preferred embodiment, see Figure 2 , Figure 3 , Figure 6 and Figure 9 The first housing 100 has a positioning station 130 on the side facing the second housing 200, suitable for placing the component 300 in the early stage of production assembly. The second housing 200 has a baffle 220 on the side facing the first housing 100. When the second housing 200 is in the second position relative to the first housing 100, the baffle 220 can abut against the component 300 on the positioning station 130. At this time, if the user moves the first housing 100 and / or the second housing 200, so that the second housing 200 moves from the second position to the first position relative to the first housing 100, the baffle 220 will drive the component 300 to move together, so that it moves from the positioning station 130 to the preset installation position. In this way, during production assembly, the user only needs to slide the first housing 100 and / or the second housing 200 to simultaneously complete the assembly of the first housing 100, the second housing 200, and the component 300, which is convenient to operate and has high production efficiency.

[0063] In actual production, a positioning station 130 can be formed by drawing position indicator marks on the first housing 100, such as the placement position of component 300 drawn with a dashed frame; alternatively, a baffle structure with an opening on one side can be opened at the corresponding position of the first housing 100. That is, a baffle adapted to the outline of component 300 is provided inside the first housing 100, and the baffle has an opening on the second side 150 for component 300 to slide out, which is more conducive to the accurate positioning of component 300 in the early stage of production assembly and has high assembly accuracy.

[0064] In this embodiment, see Figure 5 and Figure 6 The second position of the second housing 200 relative to the first housing 100 is determined by the side wall of the component 300 near the first side 140 when the component 300 is placed at the positioning station 130. At this time, the second housing 200 is placed at the opening of the first housing 100 and the baffle 220 abuts against the component 300. The position of the second housing 200 relative to the first housing 100 is the second position.

[0065] Specifically, the baffle 220 on the second housing 200 is preferably adapted to the contour of the component 300, which can better drive the component 300 to move during the movement, reduce the risk of positional displacement of the component 300 during the movement, and achieve high assembly accuracy. The number of baffles 220 can be one, surrounding the periphery of the component 300; or the number of baffles 220 can be multiple, with multiple baffles 220 arranged along the contour edge of the component 300.

[0066] At this time, because the baffle 220 limits the components 300 on all sides, the second housing 200 will move the components 300 together when it moves relative to the first housing 100. That is, in the production assembly and subsequent disassembly and assembly process, the first housing 100, the second housing 200 and the components 300 can be disassembled and assembled at the same time by sliding the first housing 100 and / or the second housing 200, which is convenient to operate.

[0067] Of course, in actual production, the baffle 220 can also have an opening on the side facing the second side 150. In this case, the baffle 220 can only move the component 300 in the early stage of production assembly. During subsequent maintenance and disassembly, only the relative movement between the first housing 100 and the second housing 200 is involved, and the component 300 can always remain in the preset installation position.

[0068] See Figure 2 and Figure 3To further improve the assembly accuracy of component 300, double-sided adhesive 400 can be installed at the positioning station 130 to bond component 300 to the first housing 100. The adhesive 400 has weak adhesion on one side of the first housing 100, which can limit the movement of component 300 without affecting it, thus preventing the component 300 from shifting position during movement and achieving accurate positioning of internal component 300.

[0069] The double-sided adhesive 400 preferably uses copper foil double-sided adhesive, which has the characteristics of weak adhesion and a certain rigidity to prevent the adhesive from wrinkling. More importantly, the copper foil double-sided adhesive can also realize the electrical conduction between the component 300 and the first housing 100, solving the problem of the internal component 300 being movable while being connected to the bottom housing.

[0070] Preferably, see Figure 2 and Figure 3 The first housing 100 has a first fastening hole 160 on its side wall, and the second housing 200 has a fastening block 230, which has a second fastening hole 231. In the first position, the first fastening hole 160 and the second fastening hole 231 are connected and coaxial. The fastener 500 can pass through the first fastening hole 160 and the second fastening hole 231 to lock the fastening block 230 to the first housing 100, thereby avoiding the risk that the second housing 200 may be accidentally moved to the second position due to vibration or accidental contact, causing the first housing 100 and the second housing 200 to separate.

[0071] In this embodiment, the first fastening hole 160 and the fastening block 230 mainly serve to prevent the second housing 200 from accidentally retracting to the second position. The number of them can be small, only one or two are needed. The location of the first fastening hole 160 and the fastening block 230 is not limited. They can be set on the third side 170 of the first housing 100, or on the fourth side 180 of the first housing 100. Alternatively, the first fastening hole 160 can be set on the first side 140 of the first housing 100. In this case, the fastening block 230 should be set at the end of the second housing 200. When the second housing 200 is in the first position relative to the first housing 100, the fastening block 230 abuts against the outer wall of the first side 140 of the first housing 100.

[0072] As a preferred option, see Figure 7 and Figure 10The second side 150 of the first housing 100 is provided with a first fastening hole 160. When the second housing 200 is in a first position relative to the first housing 100, the fastening block 230 on the second housing 200 can abut against the inner wall of the second side 150 of the first housing 100. This not only achieves a locking connection but also serves as a limit and indicator, allowing the user to confirm that the device has been moved into place. Preferably, there are two first fastening holes 160, located on the second side 150 near the third side 170 and the fourth side 180, respectively.

[0073] In one example embodiment, the element 300 includes a camera, the second housing 200 has a clearance hole 240 at the camera, and the second housing 200 extends a baffle 220 around the clearance hole 240 toward the first housing 100 to limit the relative movement of the camera and the second housing 200.

[0074] During production and assembly, double-sided adhesive 400 is first applied to the positioning station 130, and then the camera is attached to the double-sided adhesive 400. Next, using the side wall of the camera as a reference, the second housing 200 is assembled onto the first housing 100, at which point the second housing 200 is in the second position. Then, the second housing 200 is moved horizontally in the direction of the arrow, and the baffle 220 moves the camera along with it until the fastening block 230 touches the inner side wall of the second side 150 of the first housing 100. At this point, the second housing 200 is in the first position, the camera reaches the preset installation position, and the second engaging part 211 moves to the side of the first engaging part 121 away from the body of the second housing 200, achieving engagement and fixation. Finally, the fastener 500 is locked to achieve complete fixation of the first housing 100 and the second housing 200.

[0075] During subsequent disassembly and assembly, remove fastener 500 and push the second housing 200 to disassemble the second housing 200; after placing the second housing 200 back into the second position, slide it and lock fastener 500 to assemble.

[0076] This embodiment combines a sliding snap-fit ​​structure, which can achieve the assembly of the first housing 100 and the second housing 200 with a small number of fasteners 500. The structure is simple and low in cost, which can greatly improve the efficiency and yield of production assembly, after-sales service and maintenance.

[0077] In actual production, the second housing 200 includes, but is not limited to, a single housing, and can also be a large assembly, as long as it can be made into a sliding snap structure. The internal components 300 are not limited to cameras, and will not be elaborated here, all of which are within the protection scope of this application.

[0078] This application also provides an electronic device, including element 300 and the housing assembly provided in any of the above embodiments.

[0080] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application.
