Description

Technical Field

[0001] This disclosure relates to frame devices, and more particularly to a frame device that is easy to disassemble or assemble. Prior Technology

[0002] Mechanical or electronic products typically have a frame, which includes a plurality of mechanical components fixed together. The components are fixed together by means of adhesive or screws. These methods require auxiliary elements, such as adhesives or screws, to assist in the fixation between the two components, thus increasing production costs. Furthermore, while it is possible to fix these components by using clips, existing clips have the disadvantages of either good fixation but difficulty in disassembly or assembly, or easy disassembly or assembly but poor fixation.

[0003] In view of this, a new framework device is needed to improve the above problems. Summary of the Invention

[0004] This disclosure provides a frame device. The frame device includes: a back plate, a fastener, and a housing. The back plate has a groove. The fastener is disposed on the back plate and has a first component and a second component, the first component and the second component being disposed corresponding to the groove, and the distance between the first component and the second component varying along a certain direction. The housing has a hook, the hook having a first engaging portion and a second engaging portion, and the distance between the first engaging portion and the second engaging portion varying along the direction. The first component engages with the first engaging portion, and the second component engages with the second engaging portion.

[0017] For ease of description, "extending in a certain direction" as used in this article means extending along that direction or in the opposite direction.

[0018] The frame device disclosed herein may include at least two components, wherein the types of components may include, but are not limited to, a housing, a back plate, a substrate, a circuit board, etc. For ease of explanation, this document will use a frame device including a back plate and a housing as an example.

[0019] Please refer to Figures 1A to 1C. Figure 1A is an exploded view of a frame device 1 according to an embodiment of the present disclosure, showing the frame device 1 with its back plate 10 and housing 30 disassembled. Figure 1B is a schematic diagram of a frame device 1 according to an embodiment of the present disclosure, showing the frame device 1 with its back plate 10 and housing 30 assembled in a top view and perspective. Figure 1C is a cross-sectional view of the frame device 1 in Figure 1B along line A-A', showing the cross-sectional structure of the back plate 10 and housing 30 assembled.

[0020] As shown in Figures 1A to 1C, the frame device 1 includes a back plate 10, a fastener 20, and a housing 30. The shapes of the back plate 10, fastener 20, and housing 30 shown in the figures are examples and can be adjusted as needed. The back plate 10 has a groove 11. The fastener 20 can be disposed on the back plate 10, for example, it can be assembled to the back plate 10 or removed from the back plate 10. The fastener 20 has a first component 21 and a second component 22. The first component 21 and the second component 22 are disposed corresponding to the groove 11. In addition, there is a first distance d1 (indicated in Figure 1B) extending in a first direction (X) between the first component 21 and the second component 22, wherein the first distance d1 varies along a second direction (Y) perpendicular to the first direction (X), for example, the first distance d1 has different sizes at different positions in the second direction (Y). The housing 30 has a hook 31, the hook 31 having a first engaging portion 311 and a second engaging portion 312. There is a second distance d2 (shown in FIG. 1B) extending in a first direction (X) between the first engaging portion 311 and the second engaging portion 312, wherein the second distance d2 also varies along a second direction (Y). As shown in FIG. 1B to 1C, when the back plate 10 is combined with the housing 30, the first component 21 of the fastener 20 can be used to engage with the first engaging portion 311 of the hook 31, and the second component 22 of the fastener 20 can be used to engage with the second engaging portion 312 of the hook 31.

[0021] Next, the details of each component will be explained.

[0022] First, let's describe "backplate 10". Backplate 10 may be, for example, a plate inside an electronic or mechanical device. In one embodiment, the material of backplate 10 may include metal (e.g., but not limited to iron, copper, aluminum, steel, etc.), alloy, or plastic, or a combination thereof, and is not limited thereto.

[0023] In one embodiment, the back panel 10 further includes a first card slot 12, a second card slot 13, and a third card slot 14, wherein the second card slot 13 and the third card slot 14 are correspondingly disposed in a first direction (X). The first card slot 12, the second card slot 13, and the third card slot 14 protrude from the back panel 10. Each of the first card slot 12, the second card slot 13, and the third card slot 14 has an opening. The opening direction of the first card slot 12 is different from the opening directions of the second card slot 13 and the third card slot 14. The opening direction of the second card slot 13 is partially the same as and partially different from the opening direction of the third card slot 14. For example, part of the opening direction of the second card slot 13 and part of the opening direction of the third card slot 14 are both oriented towards the second direction (Y), while the other part of the opening direction of the second card slot 13 and the other part of the opening direction of the third card slot 14 are opposite to each other in the first direction (X).

[0024] Next, the "fastener 20" will be described. In one embodiment, the material of the fastener 20 may include metal materials, such as iron, aluminum, carbon steel or stainless steel, and is not limited thereto.

[0025] In one embodiment, the first component 21 and the second component 22 are symmetrical in shape, but are not limited thereto. In one embodiment, the fastener 20 further includes a third component 23, a fourth component 24, and a fifth component 25. The third component 23 connects the first component 21 and the second component 22; for example, one end of the third component 23 is connected to the first component 21, and the other end of the third component 23 is connected to the second component 22. The fourth component 24 is connected to the first component 21, and the fifth component 25 is connected to the second component 22. In one embodiment, the third component 23, the fourth component 24, and the fifth component 25 each extend in a first direction (X), while the first component 21 extends in a direction different from the first direction (X), and the second component 22 extends in a direction different from the first direction (X). Furthermore, the fourth component 24 extends from the connection point between the fourth component 24 and the first component 21 in the opposite direction to the first direction (X), while the fifth component 25 extends from the connection point between the fifth component 25 and the second component 22 in the first direction (X). Therefore, fastener 20 may have an opening 26. In addition, in one embodiment, the first distance d1 between the first component 21 and the second component 22 gradually decreases from the vicinity of the third component 23 toward the opening 26, but is not limited thereto.

[0026] In one embodiment, the fastener 20 and the back plate 10 are detachable or combinable together. In one embodiment, a third component 23 can be disposed in the first slot 12, a fourth component 24 can be disposed in the second slot 13, and a fifth component 25 can be disposed in the third slot 14. Because the fastener 20 has an opening 26, the first component 21 and the second component 22 of the fastener 20 can be deformed by an external force, reducing the first distance d1 between the first component 21 and the second component 22, so that the fourth component 24 and the fifth component 25 can be placed in the second slot 13 and the third slot 14, or leave from the second slot 13 and the third slot 14. In this way, the fastener 20 and the back plate 10 can be easily combined or disassembled.

[0027] Next, the "housing 30" will be described. The housing 30 may be, for example, the outer casing of an electronic or mechanical device, such as a back cover or front cover, and is not limited thereto. In one embodiment, the material of the housing 30 may include metal (e.g., but not limited to iron, copper, aluminum, steel, etc.), alloy, or plastic, or a combination thereof, and is not limited thereto.

[0028] In one embodiment, the first engaging portion 311 and the second engaging portion 312 of the latch 31 protrude from the housing 30. As shown in FIG1A, in one embodiment, the first engaging portion 311 has a first extension 311A ​​perpendicular to a surface of the housing 30 and a second extension 311B connected to the first extension 311A ​​and extending in a direction away from the second engaging portion 312. The second engaging portion 312 has a third extension 312A perpendicular to the surface of the housing 30 and a fourth extension 312B connected to the third extension 312A and extending in a direction away from the first engaging portion 311. Furthermore, as shown in FIG1B, in one embodiment, the change of the second distance d2 in the second direction (Y) may correspond to the change of the first distance d1 in the second direction (Y), for example, gradually decreasing along the second direction (Y), but is not limited thereto.

[0029] Furthermore, as shown in Figures 1A to 1C, in one embodiment, when the back plate 10 is combined with the housing 30, the first component 21 of the fastener 20 is guided through the second extension 311B of the first engaging portion 311, and the first component 21 is engaged into the first engaging portion 311 and rests against the first extension 311A. The second component 22 of the fastener 20 is guided through the fourth extension 312B of the second engaging portion 312, and the second component 22 is engaged into the second engaging portion 312 and rests against the third extension 312A. However, this is not the only embodiment.

[0030] Furthermore, due to the shape design of the fastener 20 and the hook 31, when the hook 31 is engaged with the fastener 20, the first engaging portion 311 and the first component 21 can have more interference, for example, a larger engaging force, at the location away from the opening 26, while having less interference, for example, a smaller engaging force, at the location near the opening 26. The second engaging portion 312 and the second component 22 can have more interference at the location away from the opening 26, while having less interference at the location near the opening 26. In one embodiment, the engaging force between the first engaging portion 311 and the first component 21 (or between the second engaging portion 312 and the second component 22) near the third component 23 is greater than the engaging force near the opening 26. Therefore, when the hook 31 is engaged with the fastener 20, the fastener 20 can be slightly displaced along the second direction (Y), making the engagement more secure, but this is not the only possibility.

[0031] Therefore, the frame device 1 disclosed herein has the function of easy assembly and disassembly. Alternatively, the frame device 1 disclosed herein has good fixation. Thus, the problems of the prior art can be solved.

[0032] The fastener 20 disclosed herein may also have different forms, and different embodiments of the fastener 20 will be described next. FIG2 is a schematic diagram of the fastener 20 of the first embodiment of the present disclosure, and please refer to FIG1A to FIG1C at the same time.

[0033] As shown in Figure 2, the first component 21 has a first endpoint 21a adjacent to the third component 23. The second component 22 has a second endpoint 22a adjacent to the third component 23. Furthermore, the first component 21 has a third endpoint 21b located away from the third component 23, wherein the third endpoint 21b is adjacent to the fourth component 24. The second component 22 has a fourth endpoint 22b located away from the third component 23, wherein the fourth endpoint 22b is adjacent to the fifth component 25. In one embodiment, the first endpoint 21a and the second endpoint 22a are located at the outer edge of the fastener 20, and the third endpoint 21b and the fourth endpoint 22b are located at the inner edge of the fastener 20, but this is not a limitation.

[0034] In the first direction (X), the distance between the first endpoint 21a and the second endpoint 22a can be defined as a first width W1, where the first width W1 can be considered as the maximum distance between the outer edges of the first component 21 and the outer edges of the second component 22. In the first direction (X), the distance between the third endpoint 21b and the fourth endpoint 22b can be defined as a second width W2, where an extension line E1 of the second width W2 in the first direction (X) may overlap with an edge 24t of the fourth component 24 away from the third component 23, or overlap with an edge 25t of the fifth component 25 away from the third component 23, but is not limited thereto. In one embodiment, the first width W1 is greater than the second width W2 (i.e., W1 > W2). In one embodiment, the ratio of the first width W1 to the second width W2 is greater than or equal to 1.5 (i.e., 1.5 ≤ W1 / W2). In one embodiment, the ratio of the first width W1 to the second width W2 is greater than or equal to 2 (i.e., 2 ≤ W1 / W2). In one embodiment, the ratio of the first width W1 to the second width W2 is greater than or equal to 3 (i.e., 3 ≤ W1 / W2). The above values ​​are examples, and this disclosure is not limited thereto.

[0035] In one embodiment, the second width W2 is between 10 mm and 20 mm (10 mm ≤ W2 ≤ 20 mm). In one embodiment, the second width W2 is between 11 mm and 19 mm (11 mm ≤ W2 ≤ 19 mm). In one embodiment, the second width W2 is between 12 mm and 18 mm (12 mm ≤ W2 ≤ 18 mm). In one embodiment, the second width W2 is between 13 mm and 17 mm (13 mm ≤ W2 ≤ 17 mm). In one embodiment, the second width W2 is between 14 mm and 16 mm (14 mm ≤ W2 ≤ 16 mm). The above values ​​are examples, and this disclosure is not limited thereto.

[0036] Furthermore, the third component 23 has an extending direction (e.g., a first direction (X)), and in a direction perpendicular to the extending direction (X) (e.g., a second direction (Y)), a length L is formed between an outer edge 23t of the third component 23 and a fourth endpoint 22b (or a third endpoint 21b). In one embodiment, the ratio of length L to the second width W2 is between 3 and 6 (i.e., 3 ≤ L / W2 ≤ 6). In one embodiment, the ratio of length L to the second width W2 is between 3.5 and 5.5 (i.e., 3.5 ≤ L / W2 ≤ 5.5). In one embodiment, the ratio of length L to the second width W2 is between 4 and 5 (4 ≤ L / W2 ≤ 5). The above values ​​are examples, and this disclosure is not limited thereto.

[0037] Additionally, a first included angle θ1 may exist between the first component 21 and the third component 23. In one embodiment, the first included angle θ1 is between 60 degrees and 89 degrees (60° ≦ θ1 ≦ 89°). In another embodiment, the first included angle θ1 is between 65 degrees and 85 degrees (65° ≦ θ1 ≦ 85°). In yet another embodiment, the first included angle θ1 is between 70 degrees and 80 degrees (70° ≦ θ1 ≦ 80°). A second included angle θ2 also exists between the second component 22 and the third component 23. In one embodiment, the second included angle θ2 is between 60 degrees and 89 degrees (60° ≦ θ2 ≦ 89°). In yet another embodiment, the second included angle θ2 is between 65 degrees and 85 degrees (65° ≦ θ2 ≦ 85°). In yet another embodiment, the second included angle θ2 is between 70 degrees and 80 degrees (70° ≦ θ2 ≦ 80°). The above figures are examples, and this disclosure is not limited to them.

[0038] Furthermore, as shown in Figure 2, a direction perpendicular to the first direction (X) and the second direction (Y) is defined as a third direction (Z). In this embodiment, the projection of the first component 21 or the second component 22 onto the third direction (Z) can be a straight line. The projections of the third component 23, the fourth component 24, or the fifth component 25 onto the third direction (Z) can be straight lines, but they can also be curves.

[0039] Thus, the fastener 20 of the first embodiment can be understood.

[0040] Figure 3 is a schematic diagram of the fastener 20 according to the second embodiment of this disclosure, and please also refer to Figures 1A to 2. Most features of the second embodiment are applicable to the description of the first embodiment, so the following mainly focuses on the differences.

[0041] As shown in Figure 3, in the third direction (Z), the projections of the first component 21 and the second component 22 in this embodiment can be curves. In one embodiment, the first component 21 may be bent toward the second component 22, and the second component 22 may be bent toward the first component 21. In one embodiment, the shapes of the first component 21 and the second component 22 are symmetrical, but this is not a limitation. In this embodiment, the first distance d1 between the first component 21 and the second component 22 gradually decreases from the vicinity of the third component 23 to the bend of the first component 21 and the second component 22 in the second direction (Y), and gradually increases from the bend to the opening 26, but this is not a limitation.

[0042] The first component 21 and the second component 22 may have a first radius of curvature R1. In one embodiment, the first radius of curvature R1 is between 20 mm and 50 mm (i.e., 20 mm ≤ R1 ≤ 50 mm). In another embodiment, the first radius of curvature R1 is between 22.5 mm and 47.5 mm (i.e., 22.5 mm ≤ R1 ≤ 47.5 mm). In yet another embodiment, the first radius of curvature R1 is between 25 mm and 45 mm (i.e., 25 mm ≤ R1 ≤ 45 mm). These values ​​are examples, and this disclosure is not limited thereto.

[0043] Thus, the fastener 20 of the second embodiment can be understood.

[0044] Figure 4 is a schematic diagram of the fastener 20 according to the third embodiment of this disclosure, and please also refer to Figures 1A to 3. Most features of the third embodiment are applicable to the description of the first embodiment, so the following mainly focuses on the differences.

[0045] As shown in Figure 4, the projection of the first component 21 in the third direction (Z) of this embodiment may include a plurality of curves, and the projection of the second component 22 in the third direction (Z) may also include a plurality of curves. For example, the first component 21 includes a first part 211 and a second part 212, wherein the projections of the first part 211 and the second part 212 in the third direction (Z) of the first component 21 may be different curves (e.g., having different radii of curvature), and the second component 22 includes a first part 221 and a second part 222, wherein the projections of the first part 221 and the second part 222 in the third direction (Z) of the second component 22 may be different curves (e.g., having different radii of curvature). Furthermore, the third component 23 may also be a non-linear shape, but is not limited thereto. In one embodiment, the first portion 211 of the first component 21 is bent away from the second component 22, the second portion 212 of the first component 21 is bent toward the second component 22, the first portion 221 of the second component 22 is bent away from the first component 21, and the second portion 222 of the second component 22 is bent toward the first component 21, but this is not a limitation. In one embodiment, the shapes of the first component 21 and the second component 22 are symmetrical, but this is not a limitation.

[0046] In one embodiment, the first portion 211 of the first component 21 has a second radius of curvature R2, and the second portion 212 of the first component 21 has a third radius of curvature R3. In one embodiment, the first portion 221 of the second component 22 has a second radius of curvature R2, and the second portion 222 of the second component 22 has a third radius of curvature R3. In one embodiment, the second radius of curvature R2 is different from the third radius of curvature R3, but is not limited thereto.

[0047] In one embodiment, the ratio of the second radius of curvature R2 to the third radius of curvature R3 is between 0.8 and 1.2 (i.e., 0.8 ≤ R2 / R3 ≤ 1.2). In one embodiment, the ratio of the second radius of curvature R2 to the third radius of curvature R3 is between 0.85 and 1.15 (i.e., 0.85 ≤ R2 / R3 ≤ 1.15). In one embodiment, the ratio of the second radius of curvature R2 to the third radius of curvature R3 is between 0.9 and 1.1 (i.e., 0.9 ≤ R2 / R3 ≤ 1.1). The above values ​​are examples, and this disclosure is not limited thereto.

[0048] In one embodiment, the second radius of curvature R2 is between 20 mm and 50 mm (i.e., 20 mm ≤ R2 ≤ 50 mm). In another embodiment, the second radius of curvature R2 is between 25 mm and 45 mm (i.e., 25 mm ≤ R2 ≤ 45 mm). In yet another embodiment, the second radius of curvature R2 is between 30 mm and 40 mm (i.e., 30 mm ≤ R2 ≤ 40 mm). These values ​​are examples only, and this disclosure is not limited thereto.

[0049] Therefore, the fastener 20 of the third embodiment can be understood.

[0050] In one embodiment, this disclosure can at least compare the frame device 1 with an object through mechanical observation, for example, by using the presence or absence of elements and / or the arrangement of elements as evidence of whether the object falls within the scope of protection of this disclosure patent, and is not limited thereto.
