DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as a reference, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientations. When the product is placed in different postures, the orientation may change, for example, "upper" and "lower" may be interchangeable. Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those skilled in the art.

[0051] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0052] Combination Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a watch case assembly, which includes a watch body 100, a retaining spring 200, a toggle assembly 300 and a bezel 400. It should be noted that the watch case assembly provided in the embodiment of the present application can be installed in a watch, and the bezel 400 can generally be embedded with a dial.

[0053] The snap ring 200 is sleeved on the watch body 100, and one end is connected to the watch body 100, and the other end is connected to the toggle assembly 300. The toggle assembly 300 is installed on the watch body 100, and can move between a locked position and an unlocked position along the circumference of the watch body 100. Therefore, when the toggle assembly 300 moves, the toggle assembly 300 can drive the snap ring 200 to contract or expand.

[0054] The bezel 400 includes a clamping structure, and the bezel 400 is detachably mounted on the watch body 100, wherein when the toggle assembly 300 is in the locked position, the clamping spring 200 is in an expanded state and combined with the clamping structure, so that the bezel 400 and the watch body 100 can be assembled together, and at this time, the bezel 400 cannot move relative to the watch body 100 in the axial direction. When the toggle assembly 300 is in the unlocked position, the clamping spring 200 is in a contracted state and separated from the clamping structure, so that the bezel 400 can be freed from the restriction of the watch body 100, that is, at this time, the bezel 400 can be removed from the watch body 100.

[0055] As can be seen from the above, by using the watch case assembly provided in the embodiment of the present application, the watch bezel 400 and the watch body 100 can be assembled or separated by moving the toggle assembly 300, that is, the components in the watch case assembly can be disassembled more flexibly, thereby improving replacement efficiency.

[0056] The following is combined with Figures 1 to 5 The details and functions of the watch case assembly provided in the embodiment of the present application are described in more detail.

[0057] Combination Figure 2 and Figure 3 As shown, in some embodiments, the outer side surface of the watch body 100 is provided with a first groove 110 along the circumferential direction, and the clamping spring 200 is sleeved in the first groove 110. It can be understood that by providing the first groove 110, it is easier to limit the clamping spring 200.

[0058] Combination Figure 2 and Figure 3As shown, in some embodiments, the clamping structure is arranged along the circumference of the inner side of the bezel 400, and the clamping structure is a second groove 410, and the opening of the second groove 410 is opposite to the opening of the first groove 110. When the toggle assembly 300 is in the locked position, the inner side and the outer side of the clamping spring 200 are respectively located in the first groove 110 and the second groove 410. When the toggle assembly 300 moves from the locked position to the unlocked position, the toggle assembly 300 drives the clamping spring 200 to contract until it is separated from the second groove 410. It can be understood that when the clamping spring 200 changes from the expanded state to the contracted state, the diameter of the clamping spring 200 decreases, so that the clamping spring 200 can be separated from the second groove 410. By moving the toggle assembly 300, the state of the clamping spring 200 can be flexibly changed, and it is more convenient to connect or separate the bezel 400 and the watch body 100, thereby improving the disassembly and assembly efficiency of the bezel 400. At the same time, since the same watch body 100 can be adapted to a wider variety of watch bezels 400 , the user can replace the watch bezel 400 according to his or her preferences, thereby improving the user experience.

[0059] It should be noted that the process of assembling the watch body 100 and the bezel 400 may be as follows: first, the circlip 200 is sleeved in the first groove 110, and the circlip 200 is in an expanded state. Then, the bezel 400 is axially close to the watch body 100, and a force is applied to the bezel 400 toward the watch body 100, so that the outer side of the circlip 200 is squeezed into the second groove 410, so that the circlip 200 can limit the movement of the bezel 400 relative to the watch body 100 in the axial direction, that is, the bezel 400 and the watch body 100 are assembled together. The process of disassembling the watch body 100 and the bezel 400 may be as follows: the toggle assembly 300 is pushed to the unlocking position, the toggle assembly 300 drives the circlip 200 to be in a contracted state and the outer side of the circlip 200 is separated from the second groove 410, and the bezel 400 is not restricted by the circlip 200, that is, the bezel 400 can be in a separated state from the watch body 100, and the disassembly is completed.

[0060] As shown Figure 3 As shown, in some embodiments, the watch body 100 includes a main body 120 and a raised portion 130. The raised portion 130 is stacked on the main body 120 along the axial direction of the main body 120, the outer side surface of the raised portion 130 is indented inward relative to the outer side surface of the main body 120, and the first groove 110 is provided on the outer side surface of the raised portion 130. It should be noted that the raised portion 130 may be annular.

[0061] Combination Figure 4 and Figure 5As shown, in some embodiments, the body 120 is provided with a third groove 121 and a fourth groove 122, and the third groove 121 and the fourth groove 122 are sequentially distributed in the circumferential direction of the body 120, and the opening of the third groove 121 and the opening of the fourth groove 122 are both facing the direction of detachment of the bezel 400. The toggle assembly 300 is installed in the third groove 121, one end of the clip 200 is connected to the toggle assembly 300, and the other end of the clip 200 is clamped in the fourth groove 122. It can be understood that when the toggle assembly 300 is moved, the end of the clip 200 clamped in the fourth groove 122 does not change in the circumferential direction, and the end of the clip 200 connected to the toggle assembly 300 moves with the movement of the toggle assembly 300. When the toggle assembly 300 moves toward the fourth groove 122 , the two ends of the clip 200 gradually approach each other and are in a contracted state; when the toggle assembly 300 moves away from the fourth groove 122 , the two ends of the clip 200 gradually move away from each other and are in an expanded state.

[0062] Combination Figure 4 and Figure 5 As shown, in some embodiments, the clamping spring 200 includes a first mounting portion 210, an arc-shaped elastic portion 220, and a second mounting portion 230. The arc-shaped elastic portion 220 is sleeved in the first groove 110, and the two ends of the arc-shaped elastic portion 220 are respectively connected to the first mounting portion 210 and the second mounting portion 230. The first mounting portion 210 is connected to the toggle assembly 300. The second mounting portion 230 is clamped in the fourth groove 122. It can be understood that the first mounting portion 210 can move closer to or away from the second mounting portion 230 as the toggle assembly 300 moves, so that the arc-shaped elastic portion 220 is in a contracted state or an expanded state.

[0063] Combination Figure 4 and Figure 5As shown, in some embodiments, the third groove 121 includes a first groove wall 125 and a second groove wall 126 which are arranged opposite to each other in the radial direction of the body 120, the first groove wall 125 is located outside the second groove wall 126, and the first groove wall 125 has a first notch 127. A portion of the toggle assembly 300 is embedded in the first notch 127 and can move in the first notch 127 along the circumference of the body 120. It should be noted that the user can move the position of the toggle assembly 300 by holding and toggling the portion of the toggle assembly 300 embedded in the first notch 127, which improves the convenience of user operation, that is, it is more convenient for the user to disassemble the bezel 400 from the watch body 100. It can be understood that when the toggle assembly 300 abuts against the side of the first notch 127 away from the fourth groove 122, the distance between the first mounting portion 210 and the second mounting portion 230 is the farthest, and the arc-shaped elastic portion 220 is in an expanded state. When the toggle assembly 300 abuts against the side of the first notch 127 close to the fourth groove 122 , the first mounting portion 210 and the second mounting portion 230 are closest to each other, and the arc-shaped elastic portion 220 is in a contracted state.

[0064] Combination Figure 4 and Figure 5 As shown, in some embodiments, the third groove 121 also includes the third groove wall 123 and the fourth groove wall 124 that are relatively arranged on the circumference of the body 120. The toggle assembly 300 includes a moving member 310 and an elastic member 320 that are connected in sequence on the circumference of the body 120, and the two ends of the elastic member 320 are respectively connected to one end of the moving member 310 and the third groove wall 123, wherein when the other end of the moving member 310 is against the fourth groove wall 124, the retaining spring 200 is in an expanded state. When the other end of the moving member 310 moves to the third groove wall 123, the retaining spring 200 is in a contracted state. It should be noted that the elastic member 320 in the embodiment of the present application has elasticity, for example, can be a spring. It is understandable that when the user pushes the other end of the moving member 310 to move to the third groove wall 123, the moving member 310 applies force to the elastic member 320, and the elastic member 320 shrinks at this moment. When the user releases the thrust applied to the moving member 310, the elastic member 320 returns to the extended state due to its elastic restoring force. At this time, the elastic member 320 can apply a thrust away from the third groove wall 123 to the moving member 310 so that the moving member 310 can automatically return to the position against the fourth groove wall 124. Such a configuration is not only convenient for pushing the moving member 310, but also convenient for the moving member 310 to automatically return to its original position, thereby improving the convenience of user operation.

[0065] Combination Figure 4 and Figure 5As shown, in some embodiments, the moving member 310 includes a first moving portion 311, a toggle portion 312, and a second moving portion 313 connected in sequence. The outer side of the toggle portion 312 is protruding relative to the first moving portion 311 and embedded in the first notch 127. The toggle portion 312 can move in the first notch 127 along the circumferential direction of the body portion 120, and the inner side of the toggle portion 312 is connected to the first mounting portion 210. The first moving portion 311 is connected to the elastic member 320. One end of the second moving portion 313 that is not connected to the toggle portion 312 abuts against or separates from the fourth groove wall 124. It should be noted that the locking position of the above-mentioned toggle assembly 300 refers to the position where the toggle portion 312 moves to abut against the side of the first notch 127 away from the fourth groove 122, and the unlocking position of the toggle assembly 300 refers to the position where the toggle portion 312 moves to abut against the side of the first notch 127 close to the fourth groove 122. It is understandable that when the end of the second moving part 313 not connected to the toggle part 312 abuts against the fourth slot wall 124, the clip 200 is in an expanded state. When the end of the second moving part 313 not connected to the toggle part 312 is separated from the fourth slot wall 124, the clip 200 is in a contracted state. The user can move the position of the toggle part 312 by holding and toggling the part of the toggle part 312 embedded in the first notch 127, so that the toggle part 312 can drive the first mounting part 210 to move, so that the arc-shaped elastic part 220 is in an expanded state or a contracted state, which improves the convenience of user operation, that is, it is more convenient for the user to disassemble the bezel 400 and the watch body 100.

[0066] like Figure 5 As shown, in some embodiments, in the circumferential direction of the body 120, the size of the first moving part 311 and the size of the second moving member 310 are both greater than the movable distance of the toggle part 312. It can be understood that the movable distance of the toggle part 312 is the distance between the toggle part 312 moving from the position of the toggle part 312 abutting against the side of the first notch 127 away from the fourth groove 122 to the position of the toggle part 312 abutting against the side of the first notch 127 close to the fourth groove 122. The first moving part 311 and the second moving member 310 are arranged according to the above-mentioned size, which can ensure that during the movement of the toggle part 312, the first moving part 311 and the second moving member 310 are always located in the third groove 121, that is, the first moving part 311 and the second moving member 310 will not be separated from the third groove 121, thereby improving the stability of the toggle assembly 300 during movement.

[0067] like Figure 4As shown, in some embodiments, the inner side of the toggle portion 312 is recessed outward to form a slot 314, and the first mounting portion 210 is locked in the slot 314. It can be understood that by providing the slot 314, the first mounting portion 210 can be limited to prevent the first mounting portion 210 from being separated from the toggle portion 312. It should be noted that the slot 314 is connected to the third groove 121, so that a space for the first mounting portion 210 to move in the radial direction of the watch body 100 can be provided. In this way, when the bezel 400 rotates in the circumferential direction, the first mounting portion 210 and the portion of the arc-shaped elastic portion 220 connected to the first mounting portion 210 can move inward in the radial direction, that is, the rotation process of the bezel 400 will not be blocked by the first mounting portion 210, and the bezel 400 is also limited by the outer side of the retaining spring 200, that is, it is limited by the outer side of the arc-shaped elastic portion 220 and will not be separated from the watch body 100, so that the user can flexibly rotate the bezel 400 according to needs. In other words, the watch case assembly provided in the embodiment of the present application has the functions of easy disassembly and flexible rotation, which increases the fun and practicality of the watch case assembly and improves the user experience.

[0068] Combination Figure 4 and Figure 5 As shown, in some embodiments, the groove wall of the first groove 110 close to the body 120 has a third notch 111. The first groove 110 and the third groove 121 are connected through the third notch 111. The first groove 110 and the fourth groove 122 are connected through the third notch 111. It should be noted that the third notch 111 provides space for the first mounting portion 210 and the second mounting portion 230 to move in the radial direction. When the user rotates the bezel 400 in the circumferential direction, since the first mounting portion 210 and the second mounting portion 230 can both move radially inward, the first mounting portion 210 and the second mounting portion 230 will not block the rotation of the bezel 400. At the same time, the bezel 400 will not be separated from the watch body 100 due to the restriction of the outer side of the retaining spring 200, that is, the outer side of the arc-shaped elastic portion 220. At this time, the user can rotate the bezel 400 more easily and flexibly according to the needs, so that the watch case assembly has both disassembly and rotation functions, which increases the fun and practicality of the watch case assembly and improves the user experience.

[0069] Combination Figure 4 and Figure 5As shown, in some embodiments, the groove wall of the first groove 110 away from the main body 120 has a fourth notch 112. The fourth notch 112 is opposite to the third notch 111, wherein, in the circumferential direction of the main body 120, the size of the fourth notch 112 is not less than the size of the third notch 111. It should be noted that the third notch 111 and the fourth notch 112 are provided, which not only enables the first mounting portion 210 and the second mounting portion 230 to move radially inward so that the bezel 400 can be flexibly rotated, but also enables the partial sections of the arc-shaped elastic portion 220 respectively connected to the first mounting portion 210 and the second mounting portion 230 to not be squeezed by the groove walls on both sides of the first groove 110 and can move inward with the first mounting portion 210 and the second mounting portion 230, so that the user can save more effort in the process of rotating the bezel 400, that is, the user can rotate the bezel 400 more flexibly and more easily.

[0070] It can be seen from the above that the watch case assembly provided by the embodiment of the present application can not only improve the efficiency of assembling or disassembling the bezel 400 and the watch body 100, so as to facilitate the user to disassemble or replace the bezel 400, thereby increasing the applicability of the watch case assembly, but also enable the bezel 400 to have the function of flexible rotation along the circumferential direction, thereby increasing the fun and practicality of the watch case assembly and improving the user experience.

[0071] Combination Figures 1 to 5 As shown, on the other hand, an embodiment of the present application further provides a watch, which includes a case assembly as described in any one of the embodiments of the present application. It should be noted that the composition and function of the case assembly are the same as those of any one of the case assemblies in the embodiments of the present application, so the embodiments of the present application are not repeated here. In some embodiments, the watch also includes a dial, and the peripheral side of the dial is connected to the watch body 100 and / or the bezel 400. It should be noted that the watch provided in the embodiment of the present application can be a smart watch, a smart bracelet, etc. Since the bezel 400 in the case assembly is easy to disassemble and rotate, it not only improves the efficiency of assembly or disassembly of the case assembly, increases the applicability of the case assembly, but also increases the fun and practicality of the case assembly, improves the user experience, and thus increases the disassembly and assembly efficiency of the watch, and also increases the fun and practicality of the watch.

[0072] Those skilled in the art will readily appreciate other embodiments of the present application after considering the specification and practicing the present application disclosed herein.
