[0011] In some embodiments, the bezel is provided with a fixing groove; the case assembly includes a fastener and a limiting member; the fastener includes the second locking portion; the limiting member is fixedly assembled with the bezel and limits the fastener in the fixing groove.

[0012] In some embodiments, the second locking portion extends out of the limiting member in a radial direction of the bezel.

[0014] In some embodiments, the bezel includes a receiving groove and a limiting groove connected to the receiving groove, and the fixing groove is formed at the bottom of the receiving groove; the limiting member includes a cover plate and a protrusion, and the cover plate extends along the circumference of the bezel and is limited in the receiving groove to cover the buckle; the protrusion is inclined to the cover plate and is located in the limiting groove.

[0015] In some embodiments, the watch case assembly includes a snap fastener, the snap fastener includes the second locking portion, and in the snap fastener, at least the second locking portion is made of an elastic material.

It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0040] like Figure 1 As shown, in related art, the watch case assembly includes a bezel 1 and a middle frame 2. It also includes a screen assembly 6. The screen assembly 6 (in this embodiment, a TP cover) is fixed to the middle frame 2 using glue. The bezel 1 is screwed to the middle frame 2 via threads 91. The number of turns of threads 91 is generally about two, and the failure of the bezel 1 to rotate properly indicates whether the assembly is complete. Of course, the bezel 1 can be removed from the middle frame 2 by rotating it in the opposite direction.

[0041] The aforementioned watch case assembly requires multiple turns of thread to connect the bezel 1 to the middle frame 2, making assembly and disassembly inconvenient. Furthermore, the threaded connection allows the bezel 1 and middle frame 2 to only be locked and unlocked. When the bezel 1 and middle frame 2 are assembled, the bezel 1 cannot be rotated to perform related functions, resulting in a poor user experience.

[0042] See also Figure 2 and Figure 3 Combined with Figure 4The present application discloses a watch case assembly. The watch case assembly includes a bezel 1 and a middle frame 2. The figure shows that there is only one bezel 1, but based on the subsequent description of the bezel 1 of the present application being detachable, there can be multiple bezels 1. Therefore, by replacing the bezel 1, the user's needs for the diversification and / or playability of the bezel 1 can be met, and the bezel 1 can be personalized. A rotating mechanism and a locking mechanism are provided between the bezel 1 and the middle frame 2. The structure of the locking mechanism is not limited to the structure described later, and it only needs to be able to lock and unlock the bezel 1 and the middle frame 2. The structure of the rotating mechanism is also limited to the structure described later, and it only needs to be able to rotate the bezel 1 relative to the middle frame 2. When the locking mechanism is in a locked state and no force is applied to the bezel 1 to rotate the bezel 1, the bezel 1 is locked relative to the middle frame 2. Figure 3 and Figure 4 The diagram illustrates the bezel 1 being locked to the middle frame 2. In this embodiment, an external force is applied to the locking mechanism to unlock the unlocking mechanism, thereby removing the bezel 1 from the middle frame 2. When the locking mechanism is unlocked and the bezel 1 is rotated, the bezel 1 rotates relative to the middle frame 2 along the circumference of the middle frame 2. Here, the unlocking mechanism can be unlocked as described below, where the force applied to rotate the bezel 1 unlocks the unlocking mechanism (i.e., rotating the bezel 1 unlocks the unlocking mechanism (the snap-fit ​​structure)). This allows consumers to unlock and rotate the bezel 1 simply by rotating the bezel 1, providing a better user experience. Of course, in another embodiment, the unlocking mechanism can be unlocked first. After unlocking, the bezel 1 and the middle frame 2 are in an active connection state, in which the bezel 1 can then be rotated.

[0043] As described above, a rotation mechanism and an unlocking mechanism are provided between the bezel 1 and the middle frame 2. When the locking mechanism is locked and no force is applied to the bezel 1, the bezel 1 is locked relative to the middle frame 2. When the locking mechanism is unlocked and the bezel is rotated, the bezel 1 rotates circumferentially along the middle frame 2 under the action of the rotation mechanism. This allows the bezel 1 and the middle frame 2 to be assembled and rotate relative to the middle frame 2, enabling multiple functions and allowing the bezel 1 to be assembled and disassembled. These two aspects make the case assembly or wearable device convenient to use and enhance the user experience. As mentioned above, when there are multiple bezels 1, the case assembly meets the user's demand for diversity and / or playability of the bezel 1, enabling personalized customization of the bezel 1.

[0044] In some embodiments, the locking mechanism has multiple locations, evenly distributed along the periphery of the middle frame 2. In this application, the locking mechanism has three locations (refer to Figure 2 Marking of the fastener 3 and Figure 11 、 Figure 13 and Figure 15 The three locking mechanisms divide the circumference of the middle frame 2 into three equal arcs. Of course, the locking mechanism is not limited to the three locations.

[0045] As configured above, since the locking mechanisms are provided in multiple locations and are evenly distributed along a circumference of the middle frame 2 , the bezel 1 and the middle frame 2 are securely locked.

[0046] In some embodiments, the rotational range of the bezel 1 is at least the distance between adjacent locking mechanisms along the circumference of the middle frame 2. For example, in the embodiment of the present application, there are three locking mechanisms. Therefore, the rotational range of the bezel 1 can be understood as one-third of the circumference of the middle frame 2 (this understanding does not take into account the width occupied by the locking mechanisms and is only for ease of understanding). Of course, in some cases, the bezel 1 can rotate a full circle, or several times (i.e., it can always rotate in one direction).

[0047] See also Figure 3 、 Figure 4 、 Figure 12 、 Figure 14 Combined with Figure 5 、 Figure 6 、 Figure 11 、 Figure 13 and Figure 15 The middle frame 2 is provided with first locking parts 21 and flanges 22 that are alternately distributed along the circumference. A gap 23 is formed between the first locking parts 21 and the flanges 22. The bezel 1 is provided with second locking parts 31 along the circumference. The locking mechanism is a snap-fit ​​structure formed by the second locking parts 31 and the first locking parts 21. Figure 3 and Figure 4 The diagram shows the first locking portion 21 and the second locking portion 31 locked together. The rotation mechanism includes the second locking portion 31 and the flange 22. Of course, as a variation of the above embodiment, the first locking portion 21 and flange 22 can be provided on the bezel 1, while the second locking portion 31 is provided on the middle frame 2.

[0048] In the above embodiment, in this embodiment, some assembly processes of the bezel 1 and the middle frame 2 are as follows:

[0049] By the alignment mark on the bezel 1, the first locking portion 21 and the second locking portion 31 are aligned, and then, in the vertical direction (such as Figure 3 The bezel 1 is then snapped into place (in the direction F shown), locking the first locking portion 21 and the second locking portion 31. This secures the bezel 1 to the middle frame 2. To remove the bezel 1, simply push upward vertically along one side of the bezel 1 (opposite to the direction F). Adjusting the degree of engagement of the buckle allows for adjustment of the removal force.

[0050] In the above embodiment, the operation of realizing the rotation of the bezel 1 is as follows: the bezel 1 is rotated, the first locking portion 21 and the second locking portion 31 are unlocked, so that the bezel 1 and the middle frame 2 are unlocked (this unlocking is not the unlocking of disassembling the bezel 1), but as the bezel 1 rotates, the second locking portion 31 is located below the flange 22 and rotates along the flange 22, thereby realizing the rotation of the bezel 1.

[0051] As described above, the locking mechanism comprises a snap-fit ​​structure formed by the second locking portion 31 and the first locking portion 21, and the rotation mechanism comprises the second locking portion 31 and the flange 22. This allows the bezel 1 to rotate relative to the middle frame 2 and be removable. Because the first and second locking portions 21 and 31 form a snap-fit ​​structure, the snap-fit ​​structure can be unlocked by engaging the second locking portion 31, allowing the bezel 1 to be removed. This results in a simple detachable structure, convenient assembly and disassembly, and a simple rotational structure. The position of the locking mechanism is also referred to as the removal position. In this position, when the second locking portion 31 is not engaged, the bezel 1 and middle frame 2 are locked. Therefore, the above-described case assembly can prevent the bezel 1 from falling off in the removal position. Finally, since a gap 23 is formed between the first locking portion 21 and the flange 22, the provision of the gap 23 not only facilitates the processing of the middle frame 2 to form the first locking portion 21 and the flange 22, but also the gap 23 is equivalent to a gap. This gap allows the bezel 1 to be removed from the middle frame 2 even when there is some deviation between the first locking portion 21 and the second locking portion 31, thereby facilitating the removal of the bezel 1.

[0052] In some embodiments, as Figure 12 As shown, the first locking portion 21 is arc-shaped, the flange 22 is arc-shaped, and the radius corresponding to the first locking portion 21 is smaller than the radius corresponding to the flange 22. Figure 12 As shown, the first locking portion 21 is closer to the interior of the middle frame 2 than the flange 22. Figure 12 The difference between the two radii is shown in FIG.

[0053] As configured above, since the radius corresponding to the first locking portion 21 is smaller than the radius corresponding to the flange 22, it is easy to control the amount of engagement between the second locking portion 31 and the first locking portion 21, thereby ensuring that the bezel 1 and the middle frame 2 are securely locked. At the same time, it is also easy to disassemble the bezel 1.

[0054] As an alternative to the above embodiment, the notch 23 is omitted between the flange 22 and the first locking portion 21. In other words, the flange 22 is a full circumference. In this case, one of the middle frame 2 and the bezel 1 is provided with a circumferential flange 22, which includes the first locking portion 21. The other of the bezel 1 and the middle frame 2 is provided with a circumferential second locking portion 31. The locking mechanism includes the second locking portion 31 and the first locking portion 21. The rotation mechanism includes the second locking portion 31 and the flange 22. For this embodiment, the rotation and detachability of the bezel 1 can be seen in the previous embodiment. Of course, this embodiment is identical to the previous embodiment except for the lack of the notch, and therefore, it also has the advantages of the previous embodiment in addition to the advantages of the previous embodiment without the notch 23.

[0055] See also Figure 9 and Figure 6 Combined with Figure 5 The watch case assembly includes a buckle 3, which includes the second locking portion 31, and also includes a buckle top 32 and a buckle bottom 33 arranged perpendicular to the bezel. Both the buckle top 32 and the buckle bottom 33 are provided with ribs 34. However, those skilled in the art will appreciate that it is sufficient for at least one of the buckle top 32 and the buckle bottom 33 to be provided with the ribs 34. Figure 8 Combined with Figure 7 and Figure 6 The bezel 1 is provided with a fixing groove 11 . The buckle 3 is clamped in the fixing groove 11 through the rib 34 .

[0056] As described above, since the snap member 3 is clamped in the fixing groove 11 by the rib 34, the assembly of the snap member 3 and the bezel 1 is simple, and the snap member 3 can be firmly located in the fixing groove 11 and is not easy to fall out or loosen from the fixing groove 11, thereby ensuring that the second locking portion 31 is locked with the first locking portion 21 and the second locking portion 31 rotates along the flange 22.

[0057] See also Figure 6 Combined with Figure 5 、 Figure 8 and Figure 10 The bezel 1 is provided with a fixing groove 11. The case assembly includes a buckle 3 and a limiter 4. The buckle 3 includes the second locking portion 31. Figure 6 and Figure 8 As can be seen from the comparison, the stopper 4 is fixedly assembled with the bezel 1. The stopper 4 can adopt any structure to be fixedly assembled with the bezel 1. After the stopper 4 is assembled, the stopper 4 limits the fastener 3 in the fixing groove 11. That is, the stopper 4 and the fixing groove 11 form a closed space, and the fastener 3 cannot escape from the closed space.

[0058] As set up above, after the limiting member 4 is fixedly assembled with the bezel 1, the fastener 3 is limited in the fixing groove 11. In this way, the fastener 3 is not easy to loosen or fall out of the fixing groove 11, ensuring that the second locking portion 31 is locked with the first locking portion 21, and the second locking portion 31 rotates along the flange 22.

[0059] See also Figure 6 The buckle 3 includes a second locking portion 31, which extends radially out of the stopper 4 along the bezel 1. The extension method is not limited to the embodiment described below. For example, the extension can be achieved through a hole, where the second locking portion 31 passes through the second hole.

[0060] As described above, since the second locking portion 31 extends radially from the bezel 1 beyond the stopper 4, it is easy to interlock (lock) or unlock the second locking portion 31 and the first locking portion 21. In addition, the second locking portion 31 extends radially from the bezel 1, and it can be considered that the second locking portion 31 and the body of the buckle 3 form an L-shape. Accordingly, the flange 22 extends along the circumference of the middle frame 2, and the flange 22 and the body of the middle frame 2 form an L-shape. Figure 4 The locking mechanism and the rotating mechanism are both matched with two L-shaped ones, and the bezel 1 is not easy to fall off and is convenient to rotate and lock.

[0061] Of course, based on the aforementioned snap-fit ​​structure formed by the first locking portion 21 and the second locking portion 31, the second locking portion 31 is not limited to extending radially. In the above embodiment, the snap-fit ​​member 3 and the bezel 1 are two separate parts. In some embodiments, the snap-fit ​​member 3 and the bezel 1 can also be integrally constructed. In other words, the bezel 1 or the middle frame 2 provided with the snap-fit ​​member 3 also includes an integral structure.

[0062] See also Figure 10 The limiting member 4 includes a limiting notch 41, see Figure 6 , the first locking portion 21 is located in the limiting notch 41. The first locking portion 21 is located in the limiting notch 41, so that the second locking portion 31 extends out of the limiting member 4.

[0063] As described above, the first locking portion 21 is located in the limiting notch 41, and the clip 3 is located in the fixing groove 11. Thus, the clip 3 is limited in all directions, such that the clip 3 is not easily loosened or removed from the fixing groove 11. This ensures that the second locking portion 31 is locked with the first locking portion 21 and that the second locking portion 31 rotates along the flange 22. Furthermore, the limiting notch 41 facilitates assembly of the clip 3 and the limiting member 4.

[0064] See also Figure 8 The bezel 1 includes a receiving groove 12 and a limiting groove 13 connected to the receiving groove 12. The fixing groove 11 is formed at the bottom of the receiving groove 12. The limiting member 4 includes a cover plate 42 and a protrusion 43. The cover plate 42 extends along the circumference of the bezel 1. Figure 6 The cover plate 42 is limited in the receiving groove 12 and covers the latch 3. The protrusion 43 is inclined to the cover plate 42. In the embodiment shown in this application, the protrusion 43 is perpendicular to the cover plate 42. Figure 6 , the protrusion 43 is located in the limiting groove 13.

[0065] As described above, the limiting member 4 is limited in the accommodating groove 12, and the protrusion 43 is located in the limiting groove 13. In this way, the limiting member 4 and the bezel 1 can be firmly assembled. Accordingly, since the buckle 3 is covered by the cover plate 42 of the limiting member 4, it is ensured that the second locking portion 31 is buckled with the first locking portion 21, and the second locking portion 31 rotates along the flange 22.

[0066] Based on the idea of ​​the first locking portion 21 and the second locking portion 31 forming a snap-fit ​​structure, at least the second locking portion 31 of the snap-fit ​​member 3 is made of an elastic material. In the present application, the snap-fit ​​member 3 is entirely made of an elastic material, such as a soft rubber material with good wear resistance and elasticity (such as TPU, fluoropolymer, etc.). The elasticity of the soft rubber can be used to facilitate the disassembly and assembly of the bezel 1, and its wear resistance can be used to reduce wear and friction during rotation. Alternatively, a hard rubber material with high self-lubricity and strength (such as PA, POM, etc.) can be used.

[0067] As described above, since at least the second locking portion 31 is made of elastic material, the second locking portion 31 and the first locking portion 21 can be easily unlocked (unfastened), thereby facilitating the assembly and disassembly of the bezel 1 and the middle frame 2 .

[0068] See also Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The bezel 1 is provided with a circle of teeth 14, and adjacent teeth 14 form tooth grooves 15. Figure 11 、 Figure 12 、 Figure 13 and Figure 14 , the middle frame 2 is provided with an elastic member 5. An embodiment of the elastic member 5 is as follows Figures 11 to 14 The spring piece is shown. As the bezel 1 rotates, the spring piece enters different grooves 15 and collides with the teeth 14 during the process of entering and exiting the grooves 15. Of course, as a variation of the above embodiment, the elastic member 5 (spring piece) can also be provided on the bezel 1, while the teeth 14 and grooves 15 are provided on the middle frame 2.

[0069] In other embodiments, see Figure 15 、 Figure 16 and Figure 17 , the elastic member 5 is a pogopin. Figure 16 and Figure 17 The pogopin comprises a sleeve 51, a spring 52, and a stopper 53. The spring 52 is located within the sleeve 51, with its ends abutting against the bottom of the sleeve 51 and the stopper 53. A stopper step 511 is provided at the top of the sleeve 51. The stopper 53 comprises a spherical crown 531 and a mating step 532 at the bottom of the crown 531. The crown 531 of the stopper 53 is located outside the sleeve 51, with the mating step 532 blocked by the stopper step 511. This prevents the stopper 53 from separating from the sleeve 51 during the deformation of the spring 52. As the bezel 1 rotates, the spherical crown 531 of the elastic member 5 (pogopin) enters different tooth grooves 15 and collides with the teeth 14 during entry and exit. Of course, as a variation of the above embodiment, the elastic member 5 (pogopin) can also be provided on the bezel 1, while the teeth 14 and tooth grooves 15 are provided on the middle frame 2. The elastic member 5 (pogo pin) of the second embodiment can realize clockwise and counterclockwise rotation (bidirectional rotation) of the bezel 1. However, the elastic member 5 (spring) of the first embodiment can only realize rotation in one direction, for example, the bezel 1 can only rotate clockwise or counterclockwise.

[0070] As set up above, through the cooperation between the elastic member 5 and the teeth 14 and the tooth grooves 15, the elastic member 5 collides with the teeth 14 to emit a rhythmic "clicking" sound, thereby realizing rotational feedback and improving user experience.

[0071] As a variation on the teeth 14 and tooth grooves 15 of the above embodiment, the teeth 14 and tooth grooves 15 can also be replaced with sockets. Although the accompanying drawings do not illustrate the sockets, the design of the teeth 14 and tooth grooves 15 can be inspired by this. If the sockets are provided on the bezel 1, they are evenly distributed around the circumference of the bezel 1. If they are provided on the middle frame 2, they are evenly distributed around the circumference of the middle frame 2. In this case, the elastic member 5 can be a pogo pin. In this embodiment, one of the bezel 1 and the middle frame 2 is provided with a socket, and the other is provided with the elastic member 5. As the bezel rotates, the elastic member 5 enters and exits the different sockets and collides with one of the bezel 1 and the middle frame 2. That is, if the elastic member 5 is provided on the middle frame 2, it collides with the bezel 1 when entering or exiting the socket. If the elastic member 5 is provided on the bezel 1, it collides with the middle frame 2 when entering or exiting the socket.

[0072] As set up above, through the cooperation between the elastic member 5 and the socket, the elastic member 5 makes a rhythmic "clicking" sound when entering and exiting the socket, thereby realizing rotational feedback and improving user experience.

[0073] In a second aspect, the present application discloses a wearable device comprising any of the aforementioned watch case components.

[0074] In some embodiments, the wearable device includes a processing module. A first component (not shown) and a second component (not shown) are disposed between the bezel 1 and the middle frame 2. The first and second components align with each other as the bezel rotates, generating an identification signal. The first and second components may be Hall effect devices, RFID components, or optical sensor components. The processing module identifies the bezel based on the identification signal. For example, the bezel 1 may be identified based on the voltage value of the identification signal. For example, the voltage corresponding to the first type of bezel 1 is a1, and the voltage corresponding to the second type of bezel 1 is a2, where a1 ≠ a2. Thus, upon receiving the identification signal corresponding to a1, the processing module can determine that the bezel 1 is the first type of bezel. Upon identifying the bezel 1, the processing module executes the function corresponding to the bezel. For example, the wearable device may store a consumer's usage habits, which are associated with the bezel. After the processing module identifies the bezel, it displays application icons corresponding to the bezel on the screen, or displays the watch face corresponding to the bezel.

[0075] As set above, by identifying the bezel to execute the function corresponding to the bezel, such as presenting a watch face of different styles, the user experience is improved.

[0076] In other embodiments, the wearable device includes a processing module, a screen component 6 and an angle detection component (not shown in the figure). The structure of the angle detection component is not limited, as long as it can detect the angle of rotation of the bezel 1. The angle detection component detects the angle of rotation of the bezel 1 relative to the middle frame 2 and generates an angle signal; the angle signal corresponds to a function one by one. The processing module performs the corresponding function according to the angle signal. For example, the menu is switched and the picture or interface is zoomed in or out by the rotation angle. For example, the degree of rotation of the bezel 1 relative to the middle frame 2 corresponds to a certain function. For example, the bezel 1 can be rotated to 90 degrees relative to the middle frame 2 to start an APP such as WeChat or Alipay, or pop up the payment interface, etc. Rotating to 120 degrees can enable the camera to take pictures, etc.

[0077] As configured above, since the bezel 1 is rotatable relative to the middle frame 2 in the assembled state and performs corresponding functions by detecting the angle, it is convenient for consumers to use and improves the user experience.

[0078] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
