Technical Field

[0001] This application relates to the technical field of watch structure, and more particularly to a watch connection structure. Background Technology

[0002] Current wristwatches typically use components such as metal connectors, screws, or spring bars to secure the strap to the case. However, such structures often require additional parts and tools, making assembly and disassembly procedures cumbersome and potentially leading to the loss or damage of parts. Furthermore, some traditional connection structures are composed of multiple parts, increasing manufacturing costs and overall weight, which can negatively impact comfort during extended wear.

Detailed Implementation

[0027] The following drawings disclose several embodiments of this application. For clarity, many implementation details will be described in the following description. However, it should be understood that these implementation details are not intended to limit the application. That is, in some embodiments of this application, these implementation details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the drawings. In the following embodiments, the same or similar components will be represented by the same reference numerals.

[0028] Please see Figures 1 to 4 , Figure 1 This is a perspective view of the watch connection structure of this application. Figure 2 yes Figure 1 A sectional view of line A-A' Figure 3 yes Figure 2 Enlarged view of region B and Figure 4 This is an exploded view of the watch connection structure of this application. As shown, this application provides a watch connection structure 1, which includes a housing 11 and a sheet metal part 12. The housing 11 has a fixing groove 111, and the bottom of the fixing groove 111 has a recess 1110. The sheet metal part 12 includes a main body 121 and a bent part 122, which are integrally formed. One end of the main body 121 extends outward and bends inward to form the bent part 122. The bent part 122 has a protrusion 1221 and a hollowed-out portion 1222. The protrusion 1221 is adjacent to the hollowed-out portion 1222. The bent part 122 is fitted into the fixing groove 111, and the protrusion 1221 of the bent part 122 is fitted into the recess 1110 of the fixing groove 111.

[0029] Please refer to the following: Figure 5 and Figure 9 , Figure 5 This is a breakdown of the watch case and sheet metal parts of this application. Figure 1 , Figure 6 It is decomposition Figure 2 , Figure 7 It is decomposition Figure 3 , Figure 8 This is a perspective view of the sheet metal part according to the first embodiment of this application and Figure 9 This is another perspective view of the sheet metal part according to the first embodiment. As shown, in this embodiment, the sheet metal part 12 is made of stainless steel and has the material strength of stainless steel. The thickness of the sheet metal part 12 ranges from 0.35 mm to 0.45 mm, with an optimal thickness of 0.4 mm. The sheet metal part 12 of this embodiment is manufactured by sheet metal fabrication, wherein the bent portion 122 includes a first bent segment 122A, a second bent segment 122B, and a third bent segment 122C, and one end of the main body extends sequentially to form the first bent segment 122A, the second bent segment 122B, and the third bent segment 122C. Thus, the overall structure of the sheet metal part 12 is manufactured in a one-piece molding manner, improving the overall structural strength.

[0030] As described above, one end of the main body 121 extends outward to form a first curved segment 122A of the curved portion 122. The width of both sides of the main body 121 is smaller than the width of both sides of the first curved segment 122A, and the two sides of the main body 121 gradually extend outward to form the first curved segment 122A. The first curved segment 122A extends inward to form a second curved segment 122B. The width of both sides of the first curved segment 122A is smaller than the width of both sides of the second curved segment 122B, and the two sides of the first curved segment 122A further extend outward to form the second curved segment 122B. Furthermore, the second curved segment 122B extends inward to form a third curved segment 122C, that is, the second curved segment 122B extends towards the side of the main body 121. The width of both sides of the second curved segment 122B is greater than the width of both sides of the third curved segment 122C, and the width of both sides of the second curved segment 122B gradually decreases inward to form the third curved segment 122C. The width of the extended ends of the third curved segment 122C is close to the width of the sides of the main body 121. In other words, the second curved segment 122B of the curved portion 122 has the largest width on both sides. The width of the second curved segment 122B is configured to match the channel length of the fixing groove 111, and the width of the extended ends of the third curved segment 122C is configured to match the width of the watch strap 13. Furthermore, the extended ends of the third curved segment 122C gradually move towards one side of the main body 121; that is, the closer the third curved segment 122C is to the main body 121, the smaller the distance between the third curved segment 122C and the first curved segment 122A becomes. The distance between the third curved segment 122C and the first curved segment 122A is configured to match the opening diameter of the fixing groove 111. This allows the curved portion 122 to fit within the fixing groove 111.

[0031] In this embodiment, the protrusion 1221 is located in the middle of the third curved segment 122C of the curved portion 122. The hollowed-out portion 1222 of the curved portion 122 has two cuts 1223 located on both sides of the protrusion 1221. The cuts 1223 are made from the side of the extended end of the third curved segment 122C of the curved portion 122, extending through the second curved segment 122B and the first curved segment 122A to the main body 121. The rigidity of the portion of the sheet metal 12 curved portion 122 cut by the cuts 1223 is compromised, and the plate in the middle of the curved portion 122 forms a cantilever structure. The cutting length of the cuts 1223 affects the structural strength; the appropriate length can be cut according to the user's needs. When the cantilever structure of the bending section 122 is subjected to external pressure, the cantilever structure has appropriate bending deformation capability. Thus, when the protrusion 1221 is compressed, the protrusion 1221 will further compress the cantilever structure in the middle of the bending section 122, and the cantilever structure of the bending section 122 will produce corresponding deformation displacement.

[0032] Please refer to the following: Figures 4 to 7 And see also Figures 10 to 12 , Figure 10 yes Figure 4 A partial sectional view of the C-C' line. Figure 11 yes Figure 1 The cross-sectional view of the D-D' line and Figure 12 This is a schematic diagram of the movement of the protrusion and the pushing component. As shown in the figure, in this embodiment, the fixing groove 111 of the housing 11 is a long straight channel, and the channel of the fixing groove 111 is an arc-shaped groove. The fixing groove 111 has a first groove opening 1111 and two second groove openings 1112. The first groove opening 1111 is positioned relative to the bottom of the fixing groove 111, that is, the first groove opening 1111 extends parallel to the channel extension direction of the fixing groove 111, and the length of the opening of the first groove opening 1111 is less than the length of the bottom of the fixing groove 111. Two second slots 1112 are located at both ends of the channel of the fixed slot 111, that is, the two second slots 1112 are located on both sides of the first slot 1111. The two second slots 1112 are connected to both sides of the first slot 1111. The two second slots 1112 are inclined relative to the bottom of the fixed slot 111. The shape of the fixed slot 111 is configured to match the bent portion 122 of the sheet metal part 12, so that the bent portion 122 of the sheet metal part 12 can be completely fitted into the fixed slot 111.

[0033] Please refer to the following: Figure 2 and Figure 3 In this embodiment, the maximum inner diameter W1 of the channel of the fixed groove 111 is greater than the opening diameter W2 of the first groove 1111. The maximum distance between the first curved segment 122A and the third curved segment 122C of the curved portion 122 is located on the side adjacent to the second curved segment 122B, that is, the maximum distance between the first curved segment 122A and the third curved segment 122C is equal to the bending distance of the second curved segment 122B. The minimum distance between the first curved segment 122A and the third curved segment 122C is located on the side adjacent to the first groove 1111, so that the distance formed between the first curved segment 122A and the third curved segment 122C gradually decreases from the bottom of the fixed groove 111 to the first groove 1111. In other words, the bending distance of the second curved segment 122B is greater than the opening diameter of the first groove 1111.

[0034] Please refer to the following: Figure 3 , Figures 5 to 7When the curved portion 122 is fitted into the fixing groove 111, the width of the two sides of the second curved segment 122B corresponds to the length of the bottom of the fixing groove 111 of the housing 11. That is, the second curved segment 122B of the curved portion 122 will fit against the bottom of the fixing groove 111, so that the second curved segment 122B and the fixing groove 111 can be tightly connected. The curvature of the first curved segment 122A and the second curved segment 122B of the curved portion 122 is the same as the curvature of the inner surface of the groove of the fixing groove 111. The first curved segment 122A and the third curved segment 122C of the curved portion 122 respectively fit against the two opposite sides of the groove in the channel of the fixing groove 111. The extended end of the third curved segment 122C and the connection between the main body 121 and the first curved segment 122A are located at the position of the first groove opening 1111. Thus, the bent portion 122 of this embodiment can completely fit the inner wall and bottom of the groove of the fixing groove 111. Since the bending distance of the second bent section 122B of the bent portion 122 is greater than the opening diameter of the first groove 1111, the sheet metal part 12 cannot be disassembled from the fixing groove 111 of the housing 11 from the direction of the first groove 1111, nor can it be assembled into the fixing groove 111 of the housing 11 from the direction of the first groove 1111.

[0035] Furthermore, in this embodiment, when the bent portion 122 is assembled into the fixing groove 111 of the housing 11, the inner side of the bent portion 122 has a channel 1220. The channel 1220 can be configured to reduce the weight of the overall sheet metal part 12, and also to provide heat dissipation for a localized space, allowing air circulation within the channel 1220. When the watch connecting structure 1 is configured to be assembled within the watch structure and worn on the user's wrist, the user feels less strain on their wrist. Simultaneously, the air circulation in the channel 1220 prevents the user from experiencing a stuffy feeling while wearing the watch.

[0036] In this embodiment, the bent portion 122 of the sheet metal part 12 is first parallel to the channel extension direction of the fixing groove 111, and then the bent portion 122 of the sheet metal part 12 is horizontally pushed into the fixing groove 111 of the housing 11 via one of the two second slots 1112. The distance between the first bent segment 122A and the third bent segment 122C of the bent portion 122 is just within the range of the second slot 1112 of the fixing groove 111, so that the protrusion 1221 located outside the third bent segment 122C will protrude beyond the range of the second slot 1112. After the bent portion 122 is pushed into the fixing groove 111, the fixing groove 111 will press the protrusion 1221 of the bent portion 122 inward, so that the protrusion 1221 will drive the cantilever structure of the bent portion 122 towards the main body 121, until the structure of the bent portion 122 is completely moved into the fixing groove 111. At this time, the protrusion 1221 will correspond to the recess 1110. The protrusion 1221 will no longer be squeezed by the fixing groove 111, and the structural restoring force of the bending part 122 will push the protrusion 1221 into the recess 1110 again. In this way, the bending part 122 of the sheet metal part 12 and the fixing groove 111 of the housing 11 form a corresponding fitting and fixation.

[0037] In this embodiment, the sheet metal part 12 includes a connecting portion 123. The other end of the main body 121 extends outward and is bent inward to form the connecting portion 123. The connecting portion 123 is configured to connect and fix the watch strap 13. The connecting portion 123 has a first connecting segment 123A and a second connecting segment 123B. The other end of the main body 121 extends outward to form the first connecting segment 123A. The first connecting segment 123A is bent inward to form the second connecting segment 123B. The first connecting segment 123A and the second connecting segment 123B are parallel to each other. The connecting portion 123 further has a first connecting port 1231 and a second connecting port 1232. The first connecting port 1231 passes through the first connecting segment 123A, and the second connecting port 1232 passes through the second connecting segment 123B. The first connecting port 1231 and the second connecting port 1232 are correspondingly connected to each other. One end of the watch strap 13 can be fixed by passing through the first connecting port 1231 and the second connecting port 1232. In this embodiment, the connecting portion 123 is formed by folding the first connecting segment 123A and the second connecting segment 123B together. This strengthens the structural strength of the connecting portion 123 of the sheet metal part 12, and the connecting portion 123 is less likely to deform due to the pulling of the watch strap 13.

[0038] Please refer to the following: Figure 11 and Figure 12In this embodiment, the housing 11 includes an internal space 110 and a pushing assembly 112. The bottom of the recess 1110 has an opening 1113, which communicates with the internal space 110. The pushing assembly 112 is located in the internal space 110 and includes a push block 1121 and a spring 1122. The push block 1121 is located in the internal space 110, and its protruding end corresponds to the opening 1113. The spring 1122 is located between the push block 1121 and the recess 1110. One end of the spring 1122 abuts against the inner wall of the internal space 110 on one side of the opening 1113, and the other end of the spring 1122 abuts against the push block 1121. The spring 1122 is a spring.

[0039] Furthermore, the housing 11 has a pressing port 1115 on the other side of the opening 1113, which communicates with the internal space 110. The pressing end of the push block 1121 protrudes from the pressing port 1115. By pressing the pressing end of the push block 1121, the protruding end of the push block 1121 is configured to push the protrusion 1221 away from the recess 1110, thus the cantilever structure of the bent portion 122 is once again pressed towards the main body 121. The bent portion 122 of the sheet metal part 12 is no longer restricted by the recess 1110. The horizontal displacement restriction of the bent portion 122 relative to the fixing groove 111 is released, and the bent portion 122 of the sheet metal part 12 can be moved out of the housing 11 again along the horizontal direction of the fixing groove 111.

[0040] Furthermore, please refer to Figure 13 and Figure 14 , Figure 13 yes Figure 11 A schematic diagram of the protrusion and recess in another embodiment and Figure 14 yes Figure 13An enlarged view of region E is shown. As illustrated, in this embodiment, the recess 1110 of the fixing groove 111 has a recess sidewall 1114, which forms an angle D1 with respect to the bottom of the fixing groove 111. When the external force that moves the bent portion 122 of the sheet metal part 12 horizontally out of the fixing groove 111 of the housing 11 is sufficiently large, the sidewall of the protrusion 1221 can be guided to move against the recess sidewall 1114 of the recess 1110. The recess sidewall 1114 of the recess 1110 will then exert a reaction force to push the protrusion 1221 toward the main body 121, thereby allowing the bent portion 122 of the sheet metal part 12 to smoothly disengage from the fixing groove 111 of the housing 11. The angle D1 ranges from greater than 90 degrees to less than 180 degrees, with an optimal angle of 120 degrees. The included angle D1 affects the structural fixing strength and disassembly force between the bent portion 122 and the fixing groove 111. In other words, the larger the included angle D1, the easier it is for the protrusion 1221 of the bent portion 122 to break free from the constraint of the recess 1110, and the less the protrusion 1221 of the bent portion 122 is constrained by the recess 1110, thus both the fixing strength and disassembly force are small. Conversely, the smaller the included angle D1, the less likely the protrusion 1221 of the bent portion 122 to break free from the constraint of the recess 1110, and the greater the constraint of the protrusion 1221 of the bent portion 122 is on the recess 1110, thus both the fixing strength and disassembly force are large. The appropriate angle can be adjusted according to the user's needs.

[0041] Furthermore, the protrusion 1221 has a protrusion sidewall 1224, which has an included angle D2 relative to the protruding end face of the protrusion 1221. When the external force that moves the bent portion 122 of the sheet metal part 12 horizontally out of the fixing groove 111 of the housing 11 is large enough, the protrusion sidewall 1224 of the protrusion 1221 can be guided to move against the sidewall of the recess 1110, and the sidewall of the recess 1110 will exert a reaction force to press the protrusion sidewall 1224 of the protrusion 1221 toward the main body 121. The above method can also smoothly disengage the bent portion 122 of the sheet metal part 12 from the fixing groove 111 of the housing 11. The angle D2 is the same as the design of the included angle D1, so it will not be described again.

[0042] In this embodiment, the bent portion 122 of the sheet metal part 12 can be directly disengaged from the fixing groove 111 of the housing 11 by providing a guide slope in the recess 1110 of the fixing groove 111, or by providing a guide protrusion sidewall 1224 in the protrusion 1221. This method eliminates the need for the pushing assembly 112 within the housing 11, allowing for more diverse structural design options. Furthermore, this embodiment does not limit the use of either the recess sidewall 1114 or the protrusion sidewall 1224, or both, as the guide slope.

[0043] Please refer to the following: Figures 15 to 16 , Figure 15 This is a perspective view of the sheet metal part according to the second embodiment of this application. Figure 16 This is another perspective view. As shown, the difference between the sheet metal part of this embodiment and the sheet metal part of the first embodiment lies in the hollow portion 1222. In this embodiment, the hollow portion 1222 has an opening 1225, and the bent portion 122 further includes a support 1226. One end of the support 1226 extends from the edge of the opening 1225 into the opening 1225, and a protrusion 1221 is provided at the extended end of the support 1226. The support 1226 extends through at least one bend within the opening 1225.

[0044] As described above, the opening 1225 extends from the extended end of the third curved segment 122C, passing through the third curved segment 122C, the second curved segment 122B, and the first curved segment 122A to one side of the main body 121. Since the bracket 1226 is located in the extended bending area of ​​the curved portion 122, the bracket 1226, in addition to being S-shaped within the opening 1225 (such as...), Figure 15 and Figure 16As shown, the bracket 1226 extends through multiple bends and deflections, and its bending extension also deforms with the bending arc of the bending portion 122. The bracket 1226 includes a first extension segment 1226A, a second extension segment 1226B, and a third extension segment 1226C. One end of the first extension segment 1226A extends horizontally from the side edge of the opening 1225 into the opening 1225 region of the first bending segment 122A, and then vertically turns towards the opening 1225 region of the second bending segment 122B. One end of the second extension segment 1226B connects to the first extension segment 1226A and bends vertically. The second extension segment 1226B extends horizontally into the opening 1225 region of the second bending segment 122B, and its horizontal extension direction is opposite to that of the first extension segment 1226A. One end of the second extension segment 1226B turns vertically again and extends towards the opening 1225 region of the third curved segment 122C. One end of the third extension segment 1226C continues vertically from the end of the second extension segment 1226B. The third extension segment 1226C extends horizontally within the opening 1225 region of the third curved segment 122C. The horizontal extension direction of the third extension segment 1226C is the same as the horizontal extension direction of the first extension segment 1226A. Finally, the extended end of the third extension segment 1226C extends and expands into a fixed end, that is, the width of the third extension segment 1226C is less than the width of the fixed end. The protrusion 1221 is provided on the fixed end of the third extension segment 1226C. The widths of the first extension segment 1226A, the second extension segment 1226B, and the third extension segment 1226C are the same. The number of bends and the width of the extended section both affect the structural strength. The more bends and the narrower the extended section, the weaker the structural rigidity, but the stronger the deformation capacity.

[0045] In this embodiment, the support 1226 of the sheet metal part 12 forms a cantilever structure relative to the opening 1225. Since the cantilever structure of the support 1226 in this embodiment has a smaller support width, in other words, the area of ​​the open portion 1222 in this embodiment is larger. Therefore, the structural rigidity of this embodiment is weaker, and the cantilever structure of the support 1226 in this embodiment has lower structural strength than the cantilever structure of the first embodiment; in other words, this embodiment provides stronger deformation capability. Apart from the structural and functional differences, the assembly, fixing, and disassembly structures of this embodiment are the same as those of the first embodiment, and therefore will not be described again.

[0046] In summary, this application provides a watch connection structure that is fixed to the case via a sheet metal component. The sheet metal component is made of a single piece of sheet metal. In addition to utilizing the elasticity of the sheet metal material itself, its openwork design also influences the rigidity of the structure, ensuring appropriate deformation capacity and strength during assembly or under stress. This allows the sheet metal component to be assembled and disassembled with the case without the need for additional tools. Simultaneously, the sheet metal component simplifies the number of parts, reduces manufacturing and assembly costs, and provides lightweight and structurally robust characteristics.
