Shell and its strip structure and water blocking frame

The invention relates to a shell and a strip structure thereof and a water blocking frame, in particular to a shell with a waterproof and dustproof effect, a strip structure and a water blocking frame.

First of all, the requirements for the waterproof and dustproof effect of electronic devices are increasing day by day. The common waterproof and dustproof methods are usually provided with a waterproof rubber strip (O-ring) between the two housings (the upper housing and the lower housing). The cross section of the strip is mostly circular or elliptical), and the waterproof strip is pressed by the rib of the upper casing and the groove of the lower casing, and is pressed by the rib of the upper casing and the groove of the lower casing. When the deformation, the waterproof rubber strip will abut against the rib and the groove to generate a reaction force, so that the waterproof rubber strip is deformed to achieve the waterproof effect.

However, the materials of the existing upper casing and the lower casing are mostly plastic materials, and in the process of injection molding, excessive warping deformation may occur (the deformation amount is severely 0.3 mm to 0.4 mm), which leads to the existing The compression amount of the O-ring (the compression amount is generally 0.2±0.05 mm) is smaller than the deformation of the upper casing and the lower casing, so that the waterproof and dustproof effect cannot be achieved, and generally, in order to achieve a better waterproof effect, it is likely to increase. The size of the waterproof strip. However, this action easily causes the reaction force of the waterproof strip to be applied to the upper and lower casings to be excessive. In this case, the hook structure for connecting the upper casing and the lower casing may be broken due to a long time due to excessive reaction force. Moreover, the waterproof rubber strip is also easily damaged by the long-term stress, and the elasticity of the waterproof rubber strip is broken. When the upper and lower casings are separated, the waterproof rubber strip is permanently deformed and cannot be restored to the original shape. And the waterproof strip must be replaced.

In addition, there is also an assembly method in which the upper and lower casings are locked by screws to fix the waterproof rubber strip between the upper casing and the lower casing. However, this design still has the possibility of rupturing the upper or lower casing due to the circular or elliptical waterproof strip.

Therefore, how to provide a rubber strip structure, a water blocking frame with a strip structure and a shell with a strip structure to overcome the above-mentioned defects has become an important subject to be solved by the technology.
