Description

A waterproof structure for electronic products

technical field

The utility model relates to a waterproof structure, in particular to a waterproof structure for electronic products.

Background technique

The waterproofing of electronic products generally uses adhesive bonding, ultrasonic welding, etc., to set a circle of silicone waterproof rings on the grooves or ribs on the plastic structural parts, or to use plastic and TPU two-color molding methods, but adhesive bonding , ultrasonic welding and other methods, due to the manual operation in the middle, the accuracy and stability of the assembly cannot be guaranteed, and the waterproof effect is not good. However, the waterproof method of plastic and TPU two-color molding, because the hardness of the TPU material is too high, the molding product The waterproof level has greater restrictions. Another waterproof method is to set a waterproof silica gel layer, but the existing waterproof silica gel layer structure is difficult to ensure its manufacturing accuracy during production, resulting in poor waterproof effect.

Contents of the invention

The technical problem to be solved by the utility model is to provide a waterproof structure for electronic products, which enhances the waterproof effect, has a simple structure, is suitable for large-scale quantitative production, reduces costs, and improves production efficiency.

In order to solve the above technical problems, the utility model takes the following technical solutions:

A waterproof structure of an electronic product, comprising a cover shell, a waterproof silica gel layer integrally formed with the cover shell, and a plastic structural part assembled with the cover shell. Waterproof bosses are provided on the surface of the waterproof silica gel layer that is joined with the plastic structural parts. The waterproof silica gel layer and the plastic structural parts are interference fit, and the waterproof bosses on the waterproof silica gel layer are interference parts during assembly.

The waterproof silicone layer is provided with waterproof bosses on the horizontal plane and the vertical plane.

The material of the waterproof silica gel layer is self-adhesive silica gel, and the waterproof silica gel layer is integrally formed with the cover shell in the mold through a two-color molding process or a secondary injection molding process.

The utility model is provided with a waterproof boss on the waterproof silica gel layer. When the cover shell is assembled with the plastic structural parts, the waterproof boss is compressed by the plastic structural parts, the gap is sealed, and the waterproof effect is remarkable. All are provided with waterproof bosses to strengthen the waterproof effect, and multiple waterproof bosses are set to achieve high-strength waterproof effects. The utility model has a simple structure, is suitable for large-scale quantitative production, can reduce costs, and improve production efficiency.

Description of drawings

Accompanying drawing 1 is the structure schematic diagram of the utility model cover shell and waterproof silica gel layer;

Accompanying drawing 2 is the schematic diagram of waterproof structure of the present utility model.

The symbols in the figure are: 1-cover shell, 2-waterproof silicone layer, 3-plastic structural parts, 4-waterproof protection area, 5-water entry area.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the utility model discloses a waterproof structure for electronic products, including a cover shell 1, a waterproof silicone layer 2 integrally formed with the cover shell 1, and a plastic structural member 3 assembled with the cover shell 1. The surface of the waterproof silica gel layer 2 that is joined with the plastic structural parts is provided with a waterproof boss. According to the waterproof strength requirements, multiple waterproof bosses can be provided. In this embodiment, two horizontal waterproof bosses are arranged on the horizontal surface of the waterproof silica gel layer 2. The boss 2B is provided with a vertical waterproof boss 2A in the vertical direction. The waterproof silicone layer 2 and the plastic structural part 3 are interference fit, and the waterproof boss is the interference part during assembly. When the cover shell 1 and the plastic structural part 3 are assembled, self-locking will occur between them, and the self-locking force will , the plastic structural part 3 will squeeze the horizontal waterproof boss 2B and the vertical waterproof boss 2A provided on the waterproof silicone layer 2, and three waterproof sealing lines will be formed between the plastic structural part and the waterproof silica gel. The water that enters from the outside enters into the water inlet area 5, and the water on the water inlet area 5 will enter the waterproof protection area 4, and it must pass through two horizontal waterproof sealing lines and one vertical waterproof sealing line, and its waterproof effect is very remarkable.

The waterproof silica gel layer 2 is made of self-adhesive silica gel, which makes the plastic structural parts not easy to fall off and enhances the waterproof effect. The waterproof silica gel layer 2 is integrally formed with the cover shell 1 in the mold through a two-color molding process or a secondary injection molding process.

The above-mentioned embodiment is a better realization scheme of the present utility model. On the premise of not departing from the inventive concept of the present utility model, any direct replacement or equivalent replacement of the present utility model is within the scope of protection of the present utility model.
