Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments of the present invention are for simplicity of description only and are not to be construed as limiting the present invention.

As shown in fig. 1 to 4, the present embodiment discloses a case structure of an electronic product (taking a watch case structure as an example, the present embodiment is also applicable to the case design of other electronic products with similar structures), which includes a ceramic outer case 1, a connecting lug 2 (the connecting lug 2 of the present embodiment is a watch ear) formed on the ceramic outer case 1 and protruding outward, and a plastic inner case 3; the 6 o 'clock position and the 12 o' clock position of ceramic package 1 all are equipped with two lugs 2 of mutual disposition (the quantity and the setting position of lug 2 can be designed according to the demand of specific electronic product, this embodiment figure 1 shows for four lugs 2), form between two lugs 2 of same position and tie up the groove of belt.

Each connecting lug 2 is provided with a groove 21 communicated with the inner cavity of the ceramic outer shell 1, the plastic inner shell 3 comprises a plastic shell 31 and a plastic body 32 which are connected, the outer wall surface of the plastic shell 31 is matched with the inner wall surface of the ceramic outer shell 1, and the plastic body 32 is matched with the groove 21, namely the plastic body 32 is filled in the groove 21. Wherein, the inner wall of the ceramic shell 1 is provided with a plurality of micropores to increase the connectivity with the plastic material during injection molding. The ceramic shell 1 and the connecting lug 2 are of an integrated structure formed by ceramic injection sintering.

In this embodiment, the plastic material is injected into the cavity and the groove 21 of the ceramic housing 1 by nano injection molding. That is, the plastic inner shell 3 is formed by nano injection molding; the plastic inner shell 3, the ceramic outer shell 1 and the connecting lug 2 are finally of an integrated structure (which can be called a nano injection molding ceramic plastic composite). The plastic inner shell 3 has the functions of buffering and preventing the micro-crack expansion of the ceramic to firmly fix the ceramic, so that the falling strength of the ceramic outer shell 1 and the connecting lug 2 can be effectively improved.

During injection molding, the plastic material is easy to generate air trapping at the concave structure where the plastic converges, once the air trapping is generated in the nano injection molding process, namely the plastic material does not enter the prepared nano holes, the plastic material does not generate tensile stress on the ceramic material, and the anti-falling capability of the ceramic nano injection molding is greatly reduced; in the embodiment, the groove 21 is communicated with the inner cavity of the ceramic shell 1, so that the problem of air trapping can be effectively solved, and the injection molding is more convenient; and the plastic inner shell 3 can be ensured not to be exposed outside the ceramic outer shell 1 (the outer part is of a ceramic structure), so that the integral aesthetic property of the shell structure of the electronic product is improved.
