Wherein, as shown in fig. 2, the part of the bezel 20 extending into the annular mounting groove 12 is provided with a second connecting piece 23, and the arrangement position of the second connecting piece 23 corresponds to the arrangement position of the first connecting piece 13, so as to ensure that the second connecting piece 13 can be connected with the first connecting piece in a matching way, thereby realizing the assembly of the bezel 20 on the middle frame 10.

Optionally, the middle frame 10, bezel 20, first connecting piece 13 and second connecting piece 23 are all made of metal.

In summary, in the watch case assembly provided by the embodiment of the present utility model, the top wall 11 of the middle frame 10 is provided with an annular mounting groove 12, and the bezel 20 is covered on the middle frame 10 and extends into the annular mounting groove 12; the first connecting piece 13 is arranged on the side wall of the annular mounting groove 12, the second connecting piece 23 is arranged on the part of the bezel 20 extending into the annular mounting groove 12, the connection between the middle frame 10 and the bezel 20 can be realized through the matched connection of the first connecting piece 13 and the second connecting piece 23, and stable electric conduction between the middle frame 10 and the bezel 20 is ensured, so that when the bezel 20 is used as an antenna radiator in the intelligent wearable device, stable and reliable antenna performance is ensured.

In the embodiment of the present utility model, as shown in fig. 2 and 3, the annular mounting groove 12 includes opposite first and second side walls 121 and 122, the first side wall 121 is closer to the center of the middle frame 10 than the second side wall 122, and the first connecting piece 13 is located on the first side wall 121 of the annular mounting groove 12; the bezel 20 may include a face cover 21 and a rim 22, the face cover 21 being disposed on the top wall 11 of the middle frame 10, one end of the rim 22 being connected to the outer periphery of the face cover 21, the other end extending into the annular mounting groove 12, and the second connecting member 23 being disposed on the inner wall of the rim 22.

As shown in fig. 2, bezel 20 includes a face cover 21 and a bezel 22; the face cover 21 is in a shape of a cake or a ring and is arranged on the top wall 11 of the middle frame 10; one end of the frame 22 is connected to the outer periphery of the face cover 21, and the other end extends into the annular mounting groove 12, so that the frame 22 is annular in shape.

As shown in fig. 3, the annular mounting groove 12 has a first side wall 121 and a second side wall 122 disposed opposite to each other, wherein the first side wall 121 is closer to the receiving cavity of the middle frame 10 than the second side wall 122, that is, closer to the center of the middle frame 10.

The first connecting piece 13 is located on the first side wall 121 of the annular mounting groove 12, and the second connecting piece 23 is correspondingly arranged on the inner wall of the frame 22 so as to be matched and connected with the first connecting piece 13.

Alternatively, as shown in fig. 3, the first and second connection members 13 and 23 are one and the other of the protrusions 131 and the grooves 231, respectively; when the middle frame 10 and the bezel 20 are coupled, the protrusions 131 are positioned in the grooves 231 and contact the walls of the grooves 231.

The middle frame 10 and the bezel 20 can be connected by the cooperation of the protrusions 131 and the grooves 231, for example, the protrusions 131 can be clamped into the grooves 231 under the action of external force and interfere with the side walls of the grooves 231, so that the protrusions 131 are not easy to separate from the grooves 231 in a normal state, and reliable connection between the middle frame 10 and the bezel 20 is realized; when the bezel 20 is required to be detached from the middle frame 10, an external force can be applied to the protrusions 131 to overcome the interference and separate from the grooves 231, thereby achieving separation of the two.

In the embodiment of the present utility model, interference is generated between the protrusion 131 and the groove 231, which means that there is an overlapping area between the front projection of the protrusion 131 on the projection plane and the front projection of the groove 231 on the projection plane, and the projection plane is the plane in which the opening of the annular mounting groove 12 is located.

Those skilled in the art will readily appreciate that the walls of the protrusion 131 and the recess 231 are necessarily in contact with each other due to interference between the protrusion 131 and the recess 231, which also facilitates electrical communication between the bezel 10 and the bezel 20 through contact between the protrusion 131 and the walls of the recess 231, where the walls of the recess 231 include side walls and a bottom wall.

Alternatively, the interference amount of the protrusion 131 and the groove 231 is 12.5% to 62.5% of the height of the protrusion 131, wherein the height direction is a radial direction of the annular mounting groove 12 or the rim 22 passing through the center of the protrusion 131.

The protrusion 131 has a root portion connected to the inner wall of the side wall or rim 22 of the annular mounting groove 12 and a top portion remote from the inner wall of the side wall or rim 22 of the annular mounting groove 12 to which it is connected. In general, the tip of the protrusion 131 is opposite to the root, in which case the height direction of the protrusion 131 can be understood as the protruding direction of the protrusion 131, i.e., the direction from the root to the tip. In the embodiment of the present utility model, since the protrusion 131 is protruded from the inner wall of the side wall of the annular mounting groove 12 or the rim 22, the protrusion 131 is protruded in the radial direction of the annular mounting groove 12 or the rim 22 to which it is connected, and accordingly, the height direction of the protrusion 131 is the radial direction of the annular mounting groove 12 or the rim 22 passing through the center of the protrusion 131.

The projection 131 and the groove 231 interfere to achieve engagement, and the interference amount is 12.5% to 62.5% of the height of the projection 131. Experiments prove that when the interference quantity is in the interval, the reliable clamping between the bulge 131 and the groove 231 can be ensured, the bulge 131 and the groove 231 are not easy to separate from each other in a normal state, the damage risk of the middle frame 10 and the bezel 20 during disassembly can be reduced, the used disassembly force is not required to be excessive, and the yield of the disassembled parts is improved.

Illustratively, the height of the protrusion 131 may be 0.08mm, and the interference amount of the protrusion 131 and the groove 231 may be any value in the range of 0.01-0.05mm, for example, may be 0.02mm, 0.03mm, or 0.04mm.

The interference amount may be regarded as a dimension of a portion where the protrusion 131 and the groove 231 interfere in the height direction of the protrusion 131. In practice, when the projection of the projection 131 on the projection plane and the projection of the recess 231 on the projection plane overlap each other, the dimension of the overlap region in the height direction of the projection 131 can be determined as the interference amount.

In some embodiments of the present utility model, the protrusions 131 extend along the circumferential direction of the annular mounting groove 12 or the rim 22 to which they are attached, the protrusions 131 extending 2% -12% of the diameter of the circle in which the first side wall 121 of the annular mounting groove 12 is located.

Generally, the longer the extension length of the protrusion 131, the larger the contact area between the protrusion 131 and the groove 231, the more reliable the electrical conduction effect, however, too long the protrusion 131 length will also result in an increase in the disassembly force required during disassembly, thereby increasing the disassembly difficulty and the risk of damaging the middle frame 10 and the bezel 20. Experiments prove that when the extension length of the protrusions 131 along the circumferential direction of the annular mounting groove 12 or the frame 22 is 2% -12% of the length of the first side wall 121 of the annular mounting groove 12, stable and reliable electric conduction between the middle frame 10 and the bezel 20 can be ensured, and the disassembly difficulty of the bezel 20 and the middle frame 10 can be within a reasonable range.

Illustratively, the diameter of the circle in which the first side wall 121 of the annular mounting groove 12 is located is 44mm, and the extension length of the protrusion 131 may be any value in the range of 1-5mm, for example, may be 2mm, 3mm, or 4mm.

As shown in fig. 1, it is easy to understand that since bezel 20 is provided to cover top wall 11 of center 10 and projections 131 and recesses 231 are respectively located on first side wall 121 of annular mounting groove 12 and the inner wall of rim 22, the direction in which projections 131 enter recesses 231 is parallel to the opening direction of annular mounting groove 12. The direction in which the protrusion 131 exits the recess 231 is opposite to the entering direction and is parallel to the opening direction of the annular mounting groove 12.

In some embodiments of the present utility model, as shown in fig. 3 and 4, the protrusion 131 has a first surface 1311 and a second surface 1312 connected in sequence in a direction in which the protrusion 131 exits the recess 231, the first surface 1311 being for connecting the second surface 1312 and an inner wall of the first side wall 121 or the rim 22 of the annular mounting groove 12 in which the protrusion 131 is located, the second surface 1312 passing over a top of the protrusion 131. Wherein the first surface 1311 is beveled to facilitate the engagement of the protrusions 131 into the grooves 231 by the first surface 1311.

In some embodiments of the present utility model, as shown in fig. 3 and 5, the groove 231 has a third side wall 2311, a bottom wall 2312 and a fourth side wall 2313 connected in sequence in a direction in which the protrusion 131 enters the groove 231, the third side wall 2311 being opposite to the fourth side wall 2313. Wherein the third side wall 2311 is inclined in such a manner as to be farther from the fourth side wall 2313 as it is farther from the bottom wall 2312, so that the protrusion 131 exits the groove 231 through the third side wall 2311.

The specific structure of the protrusion 131 and the groove 231 will be described below taking the structure and orientation shown in fig. 3 to 5 as an example, in which the protrusion 131 is provided on the first side wall 121 of the annular mounting groove 12, the groove 231 is provided on the inner wall of the bezel 22, and at this time the protrusion 131 moves upward with respect to the groove 231 into the groove 231, and the protrusion 131 moves downward with respect to the groove 231 out of the groove 231. Those skilled in the art can easily understand on this basis the directions in which the protrusions 131 enter and exit the grooves 231 when the protrusions 131 are provided on the inner wall of the rim 22 and the grooves 231 are provided on the first side wall 121 of the annular mounting groove 12, and the specific structures of the protrusions 131 and the grooves 231, respectively.

As shown in fig. 3 and 4, the protrusion 131 includes a first surface 1311 and a second surface 1312 connected in sequence from top to bottom, wherein the first surface 1311 is a slope for connecting the second surface 1312 with the first side wall 121 of the annular mounting groove 12, and the second surface 1312 passes over the top of the protrusion 131. When assembling bezel 20 and middle frame 10, protrusion 131 moves upward to approach recess 231, and first surface 1311 located above comes into contact with bezel 22 first, because first surface 1311 is sloped and is sloped so as to be closer to the bottom of annular mounting groove 12 as it is farther from first sidewall 121 of annular mounting groove 12, protrusion 131 can be easily caught in recess 231 under the influence of external force and the downward direction of first surface 1311.

As shown in fig. 3 and 5, the recess 231 includes a third side wall 2311, a bottom wall 2312 and a fourth side wall 2313 sequentially connected from bottom to top, wherein the third side wall 2311 is inclined with respect to the fourth side wall 2313, and the farther the inclination direction is from the bottom wall 2312, the farther the inclination direction is from the fourth side wall 2313. When the bezel 20 and the middle frame 10 are detached, the protrusion 131 moves downward to withdraw from the groove 231, and at this time, the third sidewall 2311 positioned below comes into contact with the protrusion 131 first and generates a relative displacement, and since the third sidewall 2311 is a slope, the protrusion 131 can withdraw from the groove 231 easily under the guiding of the third sidewall 2311 and the external force.

In some embodiments of the present utility model, as shown in fig. 6, the protrusion 131 is connected to the first side wall 121 of the annular mounting groove 12, and the second surface 1312 is a curved surface extending along the circumferential direction of the annular mounting groove 12, and the curvature of the curved surface is the same as that of the rim 22. When the protrusion 131 is snapped into the recess 231, the second surface 1312 of the protrusion 131 contacts the frame 22, and since the curvature of the second surface 1312 is the same as that of the frame 22, the contact area and the contact effect between the protrusion 131 and the frame 22 are improved, and the reliability of electrical conduction between the bezel 20 and the middle frame 10 is further improved.

In other embodiments of the present utility model, as shown in fig. 7, the protrusion 131 is connected to the inner wall of the frame 22, and the second surface 1312 is an arc surface extending along the circumferential direction of the frame 22, and the curvature of the arc surface is the same as that of the first sidewall 121 of the annular mounting groove 12. When the protrusion 131 is snapped into the recess 231, the second surface 1312 of the protrusion 131 contacts the first side wall 121 of the annular mounting groove 12, and since the curvature of the second surface 1312 is the same as that of the first side wall 121, the contact area and the contact effect between the protrusion 131 and the first side wall 121 are improved, thereby improving the reliability of electrical conduction between the bezel 20 and the middle frame 10.

Optionally, the number of the protrusions 131 is at least four, and the at least four protrusions 131 are uniformly distributed along the circumferential direction of the attached annular mounting groove 12 or the rim 22. The number of grooves 231 is at least four, and each protrusion 131 corresponds to one groove 231, or the grooves 231 are annular grooves.

As shown in fig. 8, the number of the protrusions 131 may be four, for example, the four protrusions 131 are uniformly spaced apart along the circumferential direction of the annular mounting groove 12, and a quarter arc is spaced between two adjacent protrusions 131; the groove 231 is an annular groove opened along the circumferential direction of the rim 22. When the middle frame 10 and the bezel 20 are connected, the four protrusions 131 are all located in the annular groove and interfere with the groove wall of the annular groove.

In the related art, an interference fit assembly mode is generally adopted between a face cover and a middle frame of the intelligent watch, namely, a frame of the face cover gradually inclines inwards from top to bottom, and the diameter of an opening at the bottom of the face cover is slightly smaller than the outer diameter of an opening of the middle frame; during assembly, larger pressure is applied to press the middle frame into the surface cover from the bottom opening of the surface cover, so that interference fit between the surface cover and the middle frame is realized. However, since the frame is inclined inward, the diameter of the circle where the portion of the frame closer to the face cover is located is larger, which results in that the gap between the frame and the transparent panel is not easily controlled after the transparent panel is assembled, and the transparent panel is easily shaken or misaligned.
