The invention relates to a waterproof structure which comprises a shell and a cover, wherein the cover is assembled on the shell. The shell is provided with a groove. The cover comprises a protruding rib and a soft material structure, wherein the protruding rib is coated with the soft material structure, and the protruding rib and the soft material structure are integrally formed. The soft material structure is in interference fit with the groove. Due to the arrangement of the protruding rib, when the soft material structure is in interference fit with the groove, a support of the protruding rib can make the deformation of the soft material be reliable and achieve a good waterproof effect. Meanwhile, due to the fact that the soft material structure and the cover are integrally formed, additional assembly waterproof soft rubber is not needed, the assembly deviation of the waterproof soft rubber does not need to be taken into consideration for the arrangement of magnitude of interference, and therefore the good waterproof effect is achieved through a small amount of interference, and the requirement for the structure strength of a battery cover is lowered. The invention further relates to an electronic device with the waterproof structure, for example, a mobile phone. The waterproof structure has the good waterproof effect, assembly processes are reduced, and production efficiency is improved.

An elastic member made of rubber which urges a coil portion toward a cover is formed into a shape such that the elastic member can be deformed by bending. A rate of change in reaction force of the elastic member with respect to an amount of deformation in a bending deformation region is less than a case where the elastic member is subject to compressive deformation. Therefore, even in the case where the amount of deformation of the elastic member increases due to dimensional variation of a component part, the reaction force of the elastic member does not become excessively large.

The invention relates to an orthotics. The orthotics comprises a foot support in the shape matched with the shape of the portion, needing orthopedic treatment, of a patient. The foot support comprises a function layer and a resistance layer. The function layer is made of shape memory polymer, can be softened and deforms under the preset high temperature, is hardened again under the preset low temperature with the fixed shape, and then recovers the original shape at the preset high temperature. The resistance layer is used for generating heat under the current effect so as to change the temperature of the function layer. The invention further relates to an orthopedic system. The orthopedic system comprises the orthotics and a computer system connected with the orthotics. The computer system adjusts the temperature of the orthotics by adjusting the voltage applied on the resistance layer. The orthotics has the advantages that the requirements of a patient are met by adjusting the shape of the orthotics safely and conveniently, and the service life of the orthotics is prolonged.
