DETAILED DESCRIPTION

[0032] The embodiments of the present application will be described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0033] It should be noted that when one component is considered to be "connected" to another component, it can be directly connected to the other component or can exist with a middle component. When one component is considered to be "provided on" another component, it can be directly provided on the other component or can exist with a middle component. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and the like used herein are for illustrative purposes only.

[0034] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] Please refer to Figures 1-8The embodiment of the present application provides a watch shell 100, which comprises a carbon fiber 10a shell 10 provided with a magnetic shielding inner cavity 14, the carbon fiber 10a shell 10 is provided with a first heat dissipation hole 111 and a second heat dissipation hole 121 which respectively communicate with the magnetic shielding inner cavity 14, the magnetic shielding inner cavity 14 surrounds the side edge of a dial, the carbon fiber 10a shell 10 is made of carbon fiber 10a, resin 10b and metal 10c, the first heat dissipation hole 111 and the second heat dissipation hole 121 are relatively attached to the dial along the height direction of the magnetic shielding inner cavity, and the first heat dissipation hole 111 and the second heat dissipation hole 121 are both externally penetrated into the magnetic shielding inner cavity 14.

[0036] The dial internal movement generates heat during long-time operation, the dial is placed in the magnetic shielding inner cavity 14, heat is transferred into the magnetic shielding inner cavity 14, and the heat is transferred to the outside through the first heat dissipation hole 111 and the second heat dissipation hole 121 which communicate the outside with the magnetic shielding inner cavity 14.

[0037] The magnetic shielding inner cavity 14 surrounds the side edge of the dial, the dial side edge is protected through the wrapping and attaching effect, and the impact resistance of the dial is improved. The height of the magnetic shielding inner cavity 14 is equal to the height of the dial, which is the minimum height, so that the magnetic shielding inner cavity 14 can wrap the dial.

[0038] The carbon fiber 10a shell 10 is made of carbon fiber 10a, resin 10b and metal 10c. The carbon fiber 10a is used as the main structural material, the volume proportion of the carbon fiber 10a is 60%, the high strength and light weight characteristics of the carbon fiber 10a make the watch shell 100 body keep firm while reducing the overall weight. The resin 10b (equivalent to glue) is used to weave the carbon fiber 10a together to form an overall structure. The volume proportion of the resin 10b is 30%, the resin 10b not only enhances the forming ability of the shell, but also provides good waterproof and corrosion resistance, so that the watch is still reliable in a humid environment. The metal 10c component (such as gold powder) is used to increase the strength and wear resistance of the shell, and also brings certain decorative effect. The volume proportion of the metal 10c is 10%. The heat conduction performance of the metal 10c also helps heat dissipation, preventing the internal movement from being damaged due to high temperature.

[0039] The watch shell 100 further comprises an adjusting assembly 20 and a heat dissipation piece 30. The adjusting assembly 20 and the heat dissipation piece 30 are oppositely arranged on both sides of the carbon fiber 10a shell 10. The adjusting assembly 20 and the heat dissipation piece 30 are located at one end away from the magnetic shielding inner cavity 14, and the adjusting assembly 20 is connected with the dial internally.

[0040] The adjusting assembly 20 comprises a first adjusting piece 21 and a second adjusting piece 22 (after being connected with the adjusting keys of the dial side edge, the first adjusting piece 21 and the second adjusting piece 22 have the function of adjusting watch data, such as adjusting time, date, counting and the like).

[0041] The heat dissipation piece 30 is provided with a third heat dissipation hole 31, so that the watch case 100 has three-orientation heat dissipation channels, including the first heat dissipation hole 111 on the display surface (top surface) of the dial, the second heat dissipation hole 121 on the bottom surface of the dial and the third heat dissipation hole 31 on the side of the dial, all of which are communicated to the outside by the anti-magnetic inner cavity 14, so that the heat transfer path of the dial is: dial-anti-magnetic inner cavity 14-heat dissipation hole, and the closer to the heat dissipation hole, the higher the heat generation efficiency of the electronic element can be set.

[0042] The upper shell part 11, the lower shell part 12 and the frame 13 of the carbon fiber 10a shell 10 can be integrally formed and connected together by screws. The adjusting assembly 20 and the heat dissipation piece 30 arranged on both sides of the carbon fiber 10a shell 10 can be made of carbon fiber 10a, resin 10b and metal 10c.

[0043] The utility model embodiment further provides a kind of production method of carbon fiber 10a watch case 100, and the production method includes two kinds.

[0044] Embodiment one

[0045] Embodiment one uses lay-up process, and the steps of lay-up process are as follows:

[0046] First, carbon fiber 10a fabric is laid according to predetermined angle and level, and the selection of lay-up direction needs to consider the structural strength requirement of watch case 100. Generally, the direction of lay-up includes any one or two of 0 degree, 45 degree and 90 degree fiber or the combination arrangement of three.

[0047] Then, resin 10b is heated and coated on each layer of carbon fiber 10a fabric, and carbon fiber 10a fabric and resin 10b are extruded, so that resin 10b completely infiltrates carbon fiber 10a fabric. Resin 10b not only bonds carbon fiber 10a fabric together, but also provides molding capability, corrosion resistance and waterproof performance for watch case 100 body.

[0048] Then, carbon fiber 10a fabric infiltrated with resin 10b is stacked layer by layer, and special mold is used for laminated molding. A certain pressure and temperature are used in the laminating process to ensure that each layer of material can be firmly combined and the surface is smooth without bubbles. The laminated watch case 100 body is placed in a heating device together with the mold for curing treatment. The curing process generally needs to be carried out under high pressure and high temperature for a certain time, and the pressure and temperature are adjusted according to the actual production situation. To ensure that resin 10b is completely hardened and firmly combined with carbon fiber 10a layer. After curing is completed, the watch case 100 body is cooled to room temperature, and is taken out from the mold.

[0049] Finally, the gold powder is fused with the surface of the watch case 100 to serve as decoration.

[0050] Example Two

[0051] Example Two uses a melting process, the steps of which include:

[0052] The carbon fiber 10a, resin 10b and metal 10c powders are mixed in a volume ratio of 60%:30%:10%. During the mixing process, the materials must be thoroughly and evenly mixed to ensure the mechanical properties and heat dissipation properties of the watch case 100.

[0053] The mixed materials are then heated to a molten state. The molten material is then injected into a pre-prepared mold, and high pressure is used to ensure that the material fills the mold cavity.

[0054] Finally, the mold with the injected material is cooled and set. The temperature and time during the cooling process should be controlled to ensure the strength and structural integrity of the material. After the cooling process is complete, the mold is opened and the formed watch case 100 is removed.

[0055] The above only describes the embodiments of the present application, and it should be noted that those of ordinary skill in the art can make improvements without departing from the inventive concept of the present application, and these improvements are within the scope of protection of the present application.
