Description

Technical Field

[0001] This application relates to housing structures, and more particularly to an anti-tamper housing structure. Background Technology

[0002] In modern product design, with the rapid development of technology and intensified market competition, structural protection and anti-tamper technology have become particularly important. Many high-tech products, such as smartphones, laptops, medical devices, and automotive electronic systems, not only need to prevent unauthorized disassembly by users, but also need to prevent reverse engineering and piracy by competitors.

[0003] To achieve this goal, product manufacturers have adopted a variety of advanced tamper-proof technologies. These technologies effectively protect the structural integrity of products by increasing physical barriers, making disassembly more difficult, and introducing safety mechanisms. For example, some products use special screws and tools, such as non-standard screw heads and disposable screws, increasing the complexity of disassembly; while others further enhance the product's tamper-proof capabilities through sealing and adhesive designs, such as the use of special adhesives or mechanical seals. These tamper-proof technologies not only protect the intellectual property rights of products but also improve their safety and reliability, providing additional protection for users and manufacturers.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Utility Model Content

[0005] However, the inventors discovered that while existing tamper-proof technologies improve product security to some extent, they still have some shortcomings and areas for improvement. For example, while special screws and tools increase the difficulty of disassembly, their tamper-proof effect gradually weakens as these tools become more widespread. Sealing and adhesive designs, while preventing easy disassembly of the casing, can still be damaged under extreme conditions, and repair disassembly is destructive, making reassembly difficult.

[0006] To address at least one of the aforementioned technical problems, embodiments of this application provide a housing structure. This housing structure can protect the internal structure of the product and prevent disassembly, while allowing for non-destructive disassembly via matching inserts, and enabling reassembly after disassembly.

[0007] This application provides a housing structure, including: a housing having a first guide rail and buckles; a cover plate having a second guide rail and spring pieces; wherein the second guide rail is connected to the first guide rail, allowing the cover plate to slide on the housing; the buckles are at least two oppositely arranged, and the spring pieces are at least two oppositely arranged, with each buckle and spring piece corresponding to the other.

[0008] In some embodiments, the housing further includes a tab guide groove, the first guide rail is located at a first edge of the housing and extends in a first direction; the buckle, the tab guide groove and the first guide rail are located on the same surface of the housing.

[0009] In some embodiments, there are at least two insert guide grooves arranged opposite to each other, and the ends of the insert guide grooves are provided with the undercut.

[0010] In some embodiments, the insert guide groove is configured with a corresponding insert, the insert guide groove is parallel to the first guide rail, the opening of the insert guide groove is disposed at the second edge of the housing, and the insert adapted to the insert guide groove can be inserted into the insert guide groove from the opening.

[0011] In some embodiments, the second guide rail is located at the edge of the cover plate and extends in a first direction; the spring and the second guide rail are located on the same surface of the cover plate.

[0012] In some embodiments, the first buckle of the at least two buckles is a sloping protrusion with a first vertical portion, and the second buckle of the at least two buckles is a sloping protrusion with a second vertical portion, the first vertical portion and the second vertical portion being disposed opposite to each other; the first spring piece of the at least two spring pieces has a first end protruding from the cover plate, and the second spring piece of the at least two spring pieces has a second end protruding from the cover plate, the first end and the second end being disposed opposite to each other; the distance between the first end and the second end is equal to the distance between the first vertical portion and the second vertical portion.

[0013] In some embodiments, the insert guide groove is provided with at least one protrusion, and the insert has a groove corresponding to the protrusion.

[0014] In some embodiments, the number of protrusions is two or more, and at least two or more protrusions have different positions / lengths in the first direction; the protrusions have sloping structures on both sides in the first direction.

[0015] In some embodiments, the cover plate slides along the first guide rail to a first position, the end of the first spring piece abuts against the first buckle in the buckle in a first direction, and the end of the second spring piece abuts against the second buckle in the buckle in a second direction, so that the cover plate is fixed to the housing.

[0016] In some embodiments, the insert moves along the insert guide groove, lifts the end of the spring piece, and then the spring piece disengages from the buckle. The cover plate slides along the insertion direction of the insert to leave the housing.

[0042] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] This application provides a housing structure, which includes a housing and a cover plate.

[0044] Figure 1 This is a schematic diagram of the shell structure according to an embodiment of this application. Figure 1 As shown, the outer casing structure 10 includes a housing 1 and a cover plate 2. (As indicated...) Figure 1 As shown, housing 1 and cover 2 are tightly connected and locked together. When it is necessary to release the locking between housing 1 and cover 2, the insert 3 (not shown in the figure) can be used for non-destructive disassembly.

[0045] The basic components of the shell structure of the embodiments of this application are described below.

[0046] Figure 2 This is a schematic diagram of the housing according to an embodiment of this application. Figure 2 As shown, the housing 1 has a first guide rail 11, an inverted buckle 12, and an insert guide groove 13. (As shown...) Figure 2 As shown, the first guide rail 11 is located at the first edge of the housing 1 and extends in a first direction, and the buckle 12, the insert guide groove 13, and the first guide rail 11 are located on the same surface of the housing 1. Figure 2 As shown, the insert guide groove 13 is parallel to the first guide rail 11, and the opening of the insert guide groove 13 is located at the second edge of the housing 1. There are at least two buckles 12 arranged opposite each other, and at least two insert guide grooves 13 arranged opposite each other. The end of the insert guide groove 13 is provided with a buckle 12, and the insert guide groove 13 is configured with a corresponding insert 3 (not shown in the figure). The insert 3 that is adapted to the insert guide groove 13 can be inserted into the insert guide groove 13 through the opening of the insert guide groove 13.

[0047] For example, for ease of explanation, such as Figure 2 A three-dimensional coordinate system is established as shown. The x-axis is parallel to the first edge of the housing 1, the y-axis is parallel to the second edge of the housing 1, and the z-axis is perpendicular to the plane containing the first guide rail 11, the undercut 12, and the insert guide groove 13 of the housing 1. The first edge of the housing 1 consists of two sides parallel to the x-axis, and the second edge consists of two sides parallel to the y-axis.

[0048] like Figure 2 As shown, the first guide rail 11 has two opposing sections located at the first edge of the housing 1 and extending in the x-axis direction. The first guide rail 11 has a groove in the y-axis direction, which cooperates with the second guide rail 21 of the cover plate 2 described later. Figure 2 The grooves of the first guide rail 11 shown are arranged opposite each other. This application is not limited to this. For example, they can be arranged opposite each other, i.e., arranged on the other side as shown in the figure; they can also be arranged in the same direction, i.e., both are arranged towards the positive y-axis or both are arranged towards the negative y-axis; they can also be arranged towards the positive z-axis. This application does not limit the specific shape of the guide rail.

[0049] like Figure 2 As shown, for example, for ease of explanation, the side facing the positive z-axis is referred to as the upper surface. The terms "upper" or "lower" used in this application are only used to distinguish relative directions and do not limit the direction of the structure during manufacturing and use.

[0050] In some embodiments, the inverted buckle 12, the insert guide groove 13, and the first guide rail 11 are located on the same surface of the housing 1. For example, as Figure 2 As shown, the first guide rail 11, the buckle 12, and the insert guide groove 13 of the housing 1 are all disposed on the upper surface of the housing 1.

[0051] like Figure 2 As shown, the insert guide groove 13 consists of two grooves symmetrical about the y-axis. The insert guide grooves 13 arranged opposite to each other can also be offset by a certain distance in the y-axis direction. For example, the two insert guide grooves 13 are close to two different first guide rails 11 respectively.

[0052] The insert guide groove 13 is arranged in the x-axis direction, parallel to the first guide rail 11. One end of the insert guide groove 13 is connected to the second edge of the housing 1, and has an opening on the second edge. The other end of the insert guide groove 13 is connected to the buckle 12. The insert 3 (not shown in the figure) adapted to the insert guide groove 13 can be inserted into the insert guide groove 13 through the opening. The number of insert guide grooves 13 in this application is at least two. For example, there may be two insert guide grooves 13 on the second edge of the housing 1 in the positive x-axis direction and one on the second edge of the housing 1 in the negative x-axis direction, or there may be a total of four insert guide grooves 13 arranged in pairs opposite each other.

[0053] like Figure 2 As shown, the inverted buckles 12 are two symmetrical protrusions about the y-axis. Similar to the insert guide groove 13, the oppositely arranged inverted buckles 12 can also be offset by a certain distance in the y-axis direction. The number of inverted buckles 12 corresponds to the number of insert guide grooves 13. The end of the inverted buckle 12 that protrudes relative to the housing 1 faces the insert guide groove 13.

[0054] In some embodiments, such as Figure 2 As shown, the first buckle 121 of at least two buckles 12 is a sloping protrusion with a first vertical portion 1211, and the second buckle 122 of at least two buckles 12 is a sloping protrusion with a second vertical portion 1221. The first vertical portion 1211 and the second vertical portion 1221 are arranged facing away from each other.

[0055] Figure 3 This is a schematic diagram of a cover plate according to an embodiment of this application. Figure 3 The lower surface of the cover plate 2 in contact with the housing 1 is shown. For example... Figure 3 As shown, the cover plate 2 has a second guide rail 21 and a spring piece 22. The second guide rail 21 is located at the edge of the cover plate 2 and extends in a first direction, and the spring piece 22 and the second guide rail 21 are located on the same surface of the cover plate 2.

[0056] Combination Figure 1 As shown, when the housing 1 and the cover plate 2 are assembled together, the upper surface of the cover plate 2 is not covered and is visible. The upper surface of the housing 1 and the lower surface of the cover plate 2 are connected, and the internal structure is obscured and is not visible. The second guide rail 21 of the cover plate 2 is connected to the first guide rail 11 of the housing 1, allowing the cover plate 2 to slide on the housing 1.

[0057] For example, combining Figure 1 On the lower surface of cover plate 3, establish coordinate axes x and y at the edges of cover plate 3 in two different directions, as follows: Figure 3 As shown, the second guide rail 21 extends in the x-axis direction. After the second guide rail 21 is connected to the first guide rail 11, the cover plate 2 can slide in the x-axis direction on the upper surface of the housing 1.

[0058] like Figure 3 As shown, the second guide rail 21 has a groove in the y-axis direction. Figure 3 The grooves of the second guide rail 21 shown are arranged opposite to each other. Figure 2 The grooves of the first guide rail 11 shown can engage with each other. Due to the engagement of the first guide rail 11 and the second guide rail 21, the cover plate 2 can move along the x-axis on the housing 1. This application does not limit the shape or type of the second guide rail; the groove of the second guide rail can engage with the groove of the first guide rail to fix the cover plate and the housing in the z-axis direction.

[0059] like Figure 3 As shown, there are two spring pieces 22 that are symmetrical about the y-axis. Each spring piece 22 corresponds to one of the inverted clips 12. The spring pieces 22 are positioned such that when the housing 1 and the cover plate 2 are in the following position... Figure 1 Above the inverted buckle 12 in the connected state shown. The number of spring clips 22 is equal to the number of inverted buckles 12. For example, when there are 3 inverted buckles 12, the number of spring clips 22 is also 3.

[0060] In some embodiments, such as Figure 3 As shown, the first spring 221 of at least two spring pieces 22 has a first end 2211 protruding from the cover plate 2, and the second spring 222 of at least two spring pieces 22 has a second end 2221 protruding from the cover plate 2. The first end 2211 and the second end 2221 are disposed opposite to each other. The distance between the first end 2211 and the second end 2221 is equal to the distance between the first vertical portion 1211 and the second vertical portion 1221. Thus, when the first spring piece abuts against the first buckle (the first end 2211 contacts the first vertical portion 1211), the second spring piece abuts against the second buckle (the second end 2221 contacts the second vertical portion 1221), thereby locking the cover plate and the housing together.

[0061] The above illustrations demonstrate the snap fasteners and spring clips of this application for locking and fixing. By interlocking at least two snap fasteners and spring clips arranged opposite each other, the position of the cover plate can be fixed. The simple structure prevents disassembly and improves the safety and reliability of the product.

[0062] The following describes the insert guide groove and insert used for releasing the fixation in this application. In the embodiments of this application, the insert lifts the spring piece through the insert guide groove, releasing the spring piece from the snap-fit, which can achieve non-destructive disassembly and improve the product reusability while ensuring the safety and reliability of the product.

[0063] Figure 4 This is a schematic diagram of the insert guide groove according to an embodiment of this application. Figure 4As shown, at least one protrusion 131 is provided in the insert guide groove 13. For example, there are two or more protrusions 131, and the positions / lengths of the at least two or more protrusions 131 are different in the first direction (along the x-axis direction).

[0064] For example, such as Figure 4 As shown, the insert guide groove 13 has three protrusions 131, and the distances of the three protrusions 131 from the opening of the insert guide groove 13 are all different. Furthermore, the width of each protrusion 131 along the y-axis can also be different; this application does not impose any restrictions on this. Thus, different protrusions correspond to different inserts, which can be used to correspond to different housings, thereby protecting the internal structure and further preventing disassembly.

[0065] In some embodiments, such as Figure 4 As shown, the protrusion 131 has ramp structures 1311 on both sides in the first direction. The ramps prevent the other spring clip from getting stuck during disassembly, facilitating disassembly and preventing damage to the spring clip. For example, the protrusion 131 can be... Figure 4 The convex protrusion shown has a trapezoidal cross-section along the y-axis, or a convex protrusion with one side of the cross-section along the y-axis being a circular arc with a small curvature. This application does not limit the specific shape of the protrusion and slope.

[0066] In some embodiments, such as Figure 3 As shown, the cover plate 2 also has a guide opening 23. The guide opening 23 corresponds one-to-one with the insert guide groove 13. The guide opening 23 is located on the edge of the cover plate 2 in the y-axis direction, positioned when the housing 1 and the cover plate 2 are in the following position... Figure 1 The insert guide groove 13 is located directly above the insert guide groove 13 in the connected state shown. The guide port 23 and the opening of the insert guide groove 13 form an opening that allows the insert 3 to be inserted. The wider opening design makes it easier for the insert 3 to be inserted into the insert guide groove 13.

[0067] Figure 5 This is a schematic diagram of an insert according to an embodiment of this application. Figure 5 As shown, one end of the insert 3 has a tooth 32, and the groove 31 of the tooth 32 corresponds to the protrusion 131 in the insert guide groove 13. For example, this insert 3 and Figure 4 Corresponding to the insert guide groove 13 shown, the number of grooves 31 of the insert 3 and the number of protrusions 131 of the insert guide groove 13 are equal. The length of the groove 31 is equal to the distance from the end of the corresponding protrusion 131 near the opening of the insert guide groove 131 (the outer end of the protrusion 131) to the vertical part of the corresponding buckle 12. Different numbers / positions of grooves on the insert can form different inserts, allowing the insert to function as a key.

[0068] The opening width of the insert guide groove 13 is greater than the width of the end of the insert 3 with teeth 32, allowing the insert 3 to be accommodated by the insert guide groove 13. The length of the insert 3 in the x-axis direction is greater than or equal to the length of the insert guide groove 13 in the x-axis direction, allowing the tip of the teeth 32 of the insert to abut against the corresponding undercut vertical portion. The insert 3 can be as follows: Figure 4 The T-shape shown can also be a long strip shape; this application does not limit the overall shape of the insert.

[0069] The above schematically illustrates the basic structure of the outer casing of the embodiments of this application. The following further describes the installation and disassembly of the outer casing of the embodiments of this application.

[0070] Figure 6 This is a schematic diagram of the housing installation according to an embodiment of this application. Figure 6 As shown, the housing 1 also has a screw hole 14, and a screw 4 that matches the screw hole 14 can be installed in the screw hole 14.

[0071] In some embodiments, the lower surface of the housing 1 is connected to a component of a product, such as a complex circuit board or a specific structure. The housing 1 protects the component connected to the lower surface through screw holes 14 and screws 4, and the cover plate 2 and the structure of the housing 1 further protect the screws 4 from being easily disassembled.

[0072] After the screws 4 on the housing 1 are installed, the second guide rail 21 of the cover plate 2 engages with one end of the first guide rail 11 of the housing 1, allowing the cover plate 2 to slide on the housing 1. Figures 1 to 4 The cover plate 2 slides along the first guide rail 11 to the first position (i.e., Figure 1 (As shown in the diagram), during this process, the spring piece 22 passes through the protrusion 131 of the insert guide groove 13. Due to the sloping structure 1311 on both sides of the protrusion 131, the spring piece will not be stuck or fall off quickly and cause damage during movement. When the cover plate 2 is in the first position, the first end 2211 of the first spring piece 221 in the spring piece 22 abuts against the first buckle 121 in the buckle 12 in the first direction, and the second end 2221 of the second spring piece 222 in the spring piece 22 abuts against the second buckle 122 in the buckle 12 in the second direction, so that the cover plate 2 is fixed to the housing 1. The second direction is the opposite direction to the first direction. Thus, the mutual engagement of at least two buckles and spring pieces arranged opposite to each other fixes the position of the cover plate and prevents disassembly.

[0073] For example, cover plate 2 along... Figure 6 Slide along the positive x-axis as shown, until... Figure 1When the position is shown, the corresponding spring piece 22 and the buckle 12 are in contact. Since the first spring piece 221 and the first buckle 121 restrict the movement of the cover plate 2 in the negative x-axis direction, the second spring piece 222 and the second buckle 122 restrict the movement of the cover plate 2 in the positive x-axis direction, and the first guide rail 11 and the second guide rail 21 restrict the movement of the cover plate in the y-axis and z-axis, the cover plate 2 is completely fixed and cannot move.

[0074] The insertion direction of the cover plate 2 is based on the direction in which the spring piece 22 and the corresponding snap fastener 12 can contact and abut against each other. For example, when the positions of the spring piece 22 are asymmetrical and the corresponding snap fastener 12 are also asymmetrical, and the first spring piece at the first end of the cover plate 2 corresponds to the spring piece at the second end of the housing 1, the first end of the cover plate 2 is inserted from the first end of the housing 1. When the spring piece 22 is completely symmetrical and the snap fastener 12 is completely symmetrical, the insertion direction of the cover plate 2 is not restricted. For example, the first end of the cover plate 2 can be inserted from either the first end or the second end of the housing 1.

[0075] Figure 7 This is a schematic diagram illustrating the disassembly of the outer casing according to an embodiment of this application. For example... Figure 7 As shown, the insert 3 is used to release the locking between the housing 1 and the cover plate 2, allowing the cover plate 2 to slide on the housing 1. The insert 3 moves along the insert guide groove 13, lifting the end of the spring piece 22 (not shown in the figure), after which the spring piece 22 disengages from the buckle 12, and the cover plate 2 slides away from the housing 1 along the insertion direction of the insert 3. Thus, the insert lifts the spring piece through the insert guide groove, enabling non-destructive disassembly.

[0076] Combination Figures 1 to 4 Insert 3 is located in the first position from cover 2 (i.e. Figure 1 When inserted into the insert guide groove 13 (as shown), the insert 3 can pass through the protrusion 131 of the insert guide groove 13 due to the groove 31. The teeth 32 of the insert 3 finally abut against the first vertical part 1211 of the first buckle 121 of the buckle 12, lifting the first spring piece 221 of the spring piece 22. The first spring piece 221 slides off the first buckle 121. Since the second spring piece 222 and the second buckle 122 do not restrict the movement of the cover plate 2 in the negative x-axis direction, the cover plate 2 is thus unlocked and can move. Due to the ramp structure 1311 of the protrusion 131 of the insert guide groove 13 on the other side, the moving spring piece 22 is buffered and can move smoothly in the insert guide groove 13. Finally, the cover plate 2 leaves the housing 1 from the negative x-axis direction.

[0077] This application embodiment requires only one insert to disassemble the outer casing. The direction in which the cover plate leaves the casing is the same as the insertion direction of the insert. The insert can be inserted into the corresponding insert guide slot. Alternatively, when the structures of the insert guide slots are the same, the insert can be inserted into any one of the insert guide slots to disassemble the outer casing. This application does not impose any restrictions on this.

[0078] The above embodiments are merely illustrative examples of embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments.
