DETAILED DESCRIPTION

[0043] 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.

[0044] 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 the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation. When the product is placed in different postures, the orientation may change, for example, "up" and "down" may be interchangeable.

[0045] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0046] 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.

[0047] The first aspect of the present application provides a watch case structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, the watch case structure includes a connector 1, a support member 2, a housing 3, a bezel 4 and an elastic part 5. The connector 1 is used to connect the inner side of the support member 2 and the housing 3 to limit the rotation of the support member 2 relative to the housing 3. The connector 1 can move relative to the housing 3 to connect and separate the housing 3 and the support member 2. The bezel 4 is arranged opposite to the elastic part 5. The bezel 4 is connected to the outer side of the support member 2, and the bezel 4 can rotate relative to the support member 2 to drive the elastic part 5 to vibrate.

[0048] It is understandable that the housing 3 located inside the support member 2 can support the support member 2, which is beneficial to improving the structural stability of the present application. The bezel 4 located outside the support member 2 can rotate, which is convenient for the user to input signals to the functional module through the bezel 4. The vibration generated by the elastic part 5 driven by the rotating bezel 4 can be fed back to the user.

[0049] In the embodiment of the present application, the connecting member 1 can move relative to the housing 3, and can be driven by a power source such as a motor to achieve movement relative to the housing 3, or can be pushed by a user to achieve movement. When moving, the connecting member 1 can move along a straight line to achieve connection and separation between the housing 3 and the support member 2, or can move along multiple straight lines to achieve connection and separation between the housing 3 and the support member 2. Among them, the connecting member 1 can achieve connection between the housing 3 and the support member 2 by contacting the two, and achieve separation between the two by separating from the housing 3 or the support member 2.

[0050] In the embodiment of the present application, the support member 2 can be directly mounted on the housing 3 to support the bezel 4 so that it can rotate, which is beneficial for designers to use the existing housing 3 as the housing 3 of the watch case structure of the present application. In the embodiment of the present application, the support member 2 can be a ring structure.

[0051] In the embodiment of the present application, the bezel 4 plays a role in protecting the housing 3 to a certain extent, and the way in which the bezel 4 drives the elastic part 5 to vibrate can be: repeatedly squeezing the elastic part 5 multiple times to make it elastically deformed, and when the elastic deformation is restored, it collides with the bezel 4 to generate vibration. In the embodiment of the present application, the bezel 4 can be a ring structure.

[0052] In the embodiment of the present application, the elastic part 5 can be connected to the housing 3 by dispensing or the like. The number of the elastic parts 5 can be 1, 2, or 3, or other numbers. Two or more elastic parts 5 can be arranged in sequence along the rotation direction of the bezel 4.

[0053] In some of the embodiments of this application, Figure 3 As shown, the case structure includes a limiting member 6, which is located between the bezel 4 and the support member 2 to limit the separation of the bezel 4 from the support member 2.

[0054] It can be understood that the stopper 6 can improve the compactness of the case structure of the present application by limiting the separation of the bezel 4 from the support 2, and reduce the case structure of the present application from being disintegrated due to collision. The stopper 6 is located between the bezel 4 and the support 2, and can interfere with the bezel 4, so that the bezel 4 can rotate around its rotation axis, but is restricted when moving along the extension direction of the rotation axis.

[0055] In some of the embodiments of this application, Figure 4 As shown, the bezel 4 has a first limiting groove 401, the support member 2 has a second limiting groove 201, the opening of the first limiting groove 401 is arranged opposite to the opening of the second limiting groove 201, at least a portion of the limiting member 6 is located in the first limiting groove 401, and at least a portion of the limiting member 6 is located in the second limiting groove 201.

[0056] It can be understood that the first limiting groove 401 and the second limiting groove 201 are conducive to the bezel 4 and the support member 2 to accommodate the limiting member 6. On the one hand, it can realize the limiting effect of the limiting member 6 on the bezel 4, and on the other hand, it can also reduce the difficulty of assembly and manufacturing of the limiting member 6.

[0057] In some embodiments of the present application, the first limiting groove 401 and the second limiting groove 201 are generally annular, and the limiting member 6 is located in the first limiting groove 401 and the second limiting groove 201 to limit the bezel 4. Figure 5 As shown, the limiting member 6 includes a plurality of limiting sub-sections 61, which are connected in sequence, and an angle greater than 90° is formed between two adjacent limiting sub-sections 61. This is conducive to improving the limiting effect of the limiting member 6.

[0058] It can be understood that an angle greater than 90° is formed between two adjacent limiting sub-sections 61, so that the two adjacent limiting bytes form a protrusion. The protrusion will enable each of the above two limiting sub-sections 61 to maintain a posture in which a part is located in the first limiting groove 401 and the other part is located in the second limiting groove 201, which is conducive to the limiting member 6 maintaining its limiting effect.

[0059] In the embodiment of the present application, the limiting member 6 can be formed by stamping a steel wire.

[0060] In the embodiment of the present application, the limiting member 6 may be in the shape of a broken ring.

[0061] In the embodiment of the present application, the number of angles may be 4, 5, 6, 7 or 8, or any other number.

[0062] In the embodiment of the present application, the diameter of the limiting sub-section 61 can be 0.4 mm, 0.5 mm or 0.6 mm, or other sizes.

[0063] In some of the embodiments of this application, Figure 3 As shown, the housing 3 has a movable groove 301 , and the connecting member 1 is connected to the housing 3 in the movable groove 301 . The connecting member 1 can move relative to the movable groove 301 to abut against and separate from the supporting member 2 .

[0064] In the embodiment of the present application, the movable groove 301 can provide a space for the connector 1 to move, which is conducive to hiding the connector 1 in the housing 3 and preventing the connector 1 from protruding from the housing 3. When the connector 1 abuts against the support member 2, it can connect the housing 3 and the support member 2, thereby limiting the movement of the support member 2 relative to the housing 3, which is conducive to improving the stability of the bezel 4 on the housing 3 and generating vibration through rotation. When the connector 1 is separated from the support member 2, the support member 2 can drive the bezel 4 to come off the housing 3, which is conducive to the user replacing the bezel 4.

[0065] In some of the embodiments of this application, Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, the support member 2 has a slot 202, which is located on the inner side of the support member 2. The connector 1 includes a buckle 11 and a reset portion 12. The buckle 11 is located in the movable slot 301. The buckle 11 can move relative to the movable slot 301 to extend into and exit from the slot 202. The reset portion 12 is used to apply a reset force to the connector 1 to extend into the slot 202 when the buckle 11 exits the slot 202.

[0066] It is understandable that when the buckle 11 is inserted into the slot 202, it can be connected with the support member 2, which is conducive to the support member 2 supporting the bezel 4 to rotate. When the buckle 11 is withdrawn from the slot 202, it is separated from the support member 2, which is convenient for the user to replace the bezel 4. The reset portion 12 applies a reset force to the buckle 11 so that it remains connected with the support member 2 when it is not subjected to other external forces (such as the thrust generated by the user's squeezing).

[0067] In the embodiment of the present application, the side of the buckle 11 where the reset portion 12 is located has a hole for accommodating the reset portion 12 , which can guide and limit the reset portion 12 .

[0068] In the embodiment of the present application, the reset portion 12 may be a spring.

[0069] In some of the embodiments of this application, Figure 3 As shown, the movable groove 301 extends to the edge of the housing 3 along the moving direction of the buckle 11 .

[0070] It can be understood that the movable groove 301 extending to the edge of the housing 3 is conducive to the user applying a thrust to the buckle 11, and the thrust can separate the buckle 11 from the support 2, thereby facilitating the user to replace the bezel 4.

[0071] In the embodiment of the present application, both sides of the buckle 11 can be restricted in the movable groove 301 by a cover plate or other structure to reduce the possibility of the buckle 11 falling off.

[0072] In some of the embodiments of this application, Figure 7 As shown, the bezel 4 includes a plurality of teeth 41 , which are arranged at intervals along the rotation direction of the bezel 4 , and the teeth 41 are arranged opposite to the elastic portion 5 .

[0073] It is understandable that the teeth 41 can squeeze the elastic part 5, causing the elastic part 5 to undergo elastic deformation. When the teeth 41 separate from the elastic part 5, the elastic part 5 recovers and collides with the spaced position of the adjacent teeth 41, thereby causing the bezel 4 to vibrate.

[0074] In some of the embodiments of this application, Figure 6 As shown, the elastic portion 5 includes a top ball 51 and a spring 52 . The spring 52 connects the top ball 51 and the housing 3 . The top ball 51 and the tooth portion 41 are arranged opposite to each other along the extending direction of the spring 52 .

[0075] It is understandable that when the top ball 51 is squeezed by the teeth 41, the squeezing will act on the spring 52, causing it to generate elastic force. When the squeezing of the bezel 4 is removed, the elastic force will drive the top ball 51 to move toward the bezel 4 and collide with the bezel 4. Such repeated collisions will cause the bezel 4 to vibrate, which will then be fed back to the user.

[0076] A second aspect of the present application provides a bezel structure, which includes a support member 2 and a bezel 4, wherein the support member 2 is used for detachable connection with the housing 3, and the bezel 4 is connected to the support member 2 and can rotate relative to the support member 2.

[0077] It can be understood that the support member 2 is used to be detachably connected to the housing 3, so that the support member 2 can support the bezel 4. The support member 2 provides support for the rotation of the bezel 4, so that it can rotate. The rotatable bezel 4 is conducive to the user outputting a signal to the electronic device, so that it realizes the function corresponding to the signal, and improves the convenience of the user's interaction with the electronic device.

[0078] In some embodiments of the present application, the bezel structure includes a limiting member 6 , which is located between the bezel 4 and the support member 2 to limit the separation of the bezel 4 from the support member 2 .

[0079] It can be understood that the limiting member 6 can improve the connection performance between the bezel 4 and the support member 2 and reduce the situation where the bezel 4 and the support member 2 are separated due to collision.

[0080] In some embodiments of the present application, the bezel 4 has a first limiting groove 401, the support member 2 has a second limiting groove 201, the opening of the first limiting groove 401 is arranged opposite to the opening of the second limiting groove 201, at least a portion of the limiting member 6 is located in the first limiting groove 401, and at least a portion of the limiting member 6 is located in the second limiting groove 201.

[0081] It is understandable that when the bezel 4 has a tendency to separate from the support member 2, the first limiting groove 401 will move relative to the second limiting groove 201. Since at least a portion of the limiting member 6 is located in the first limiting groove 401 and at least a portion of the limiting member 6 is located in the second limiting groove 201, the first limiting groove 401 will be interfered by the limiting member 6 when it moves, so that the connection performance between the bezel 4 and the support member 2 can be improved.

[0082] In some embodiments of the present application, the limiting member 6 includes a plurality of limiting sub-sections, the plurality of limiting sub-sections are connected in sequence, and an angle greater than 90° is formed between two adjacent limiting sub-sections.

[0083] It can be understood that an angle greater than 90° is formed between two adjacent limiting sub-sections, which is beneficial for each limiting sub-section to be located in the first limiting groove 401 and the second limiting groove 201 at the same time, thereby improving the connection performance of the limiting member 6 to the bezel 4 and the support member 2.

[0084] In some embodiments of the present application, the bezel 4 includes a tooth portion 41 , and a plurality of tooth portions 41 are arranged at intervals along the rotation direction of the bezel 4 .

[0085] It can be understood that the teeth 41 facilitate the collision between the bezel 4 and the housing 3 when the bezel 4 rotates. The reciprocating collision can cause the bezel 4 to vibrate. The vibration can be fed back to the user through the bezel 4.

[0086] In some embodiments of the present application, the support member 2 has a slot 202 .

[0087] It is understandable that the card slot 202 can be used to form a card connection between components of the electronic device, and help the support member 2 support the bezel 4 so that it can rotate.

[0088] A third aspect of the present application provides an electronic device, which includes the case structure and / or bezel structure as described in the above embodiments.

[0089] It can be understood that, due to the adoption of the case structure of the above-mentioned embodiment, the electronic device of the present application has the same technical effect as the above-mentioned embodiment, which will not be repeated here.

[0090] In the embodiment of the present application, the electronic device may be a smart watch.

[0091] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0092] 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.
