[0002] With the continuous development of science and technology, smart phones play an increasingly important role in people's daily life and work. However, in the special environment of coal mines, ordinary mobile phones have safety hazards, so special explosion-proof mobile phones are needed. Their circuit boards, batteries and other components are specially designed and processed to have certain explosion-proof functions. In coal mines, due to the presence of flammable and explosive substances such as gas and coal dust, explosion-proof mobile phones must be used to ensure safe production.

[0003] Explosion-proof mobile phones need to consider multiple factors, including explosion-proof level, battery safety, communication quality, functional requirements and price cost, among which the explosion-proof function is the most basic and important feature of explosion-proof mobile phones. It usually uses its rear shell structure as a protective component of the entire explosion-proof mobile phone. However, the existing rear cover protection structure for explosion-proof mobile phones is mostly in the form of a single shell cover. The self-compression and impact resistance performance is not strong enough, and the buffering and shock absorption effect is poor, and it cannot play a stable impact-resistant protection role. To this end, those skilled in the art provide a mining explosion-proof mobile phone protection structure with strong impact resistance and durability to solve the problems raised in the above background technology.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Please refer to Figure 1-4 As shown, a mining explosion-proof mobile phone protection structure with strong impact resistance and durability comprises a back cover 1, an anti-collision cover 2 wrapped around the outside of the back cover 1, and a heat dissipation substrate 3 installed in the bottom plate of the back cover 1 shell. The anti-collision cover 2 is made of silicone material, and the heat dissipation substrate 3 is made of aluminum alloy material. The heat dissipation substrate 3 in the form of aluminum alloy is used as an inner support for the back cover 1, and the anti-collision cover 2 in the form of silicone material is used as an outer cover for the back cover 1. It can form a good inner support reinforcement and outer anti-collision form, which can improve the firmness, hardness and impact resistance of the overall structure on the one hand, and strengthen its elastic anti-collision buffering performance on the other hand, and play a good hard and soft impact resistance.

[0026] The anti-collision cover 2 includes an edge cover 21, and the upper and lower ends of the edge cover 21 are both provided with extended convex edges 22 protruding from the back cover 1, and the two sides of the edge cover 21 are symmetrically provided with anti-skid convex edges 23, the extended convex edges 22 are chamfered structures, and the anti-skid convex edges 23 are toothed structures. By arranging the extended convex edges 22 protruding outward on the anti-collision cover 2, the back plate and the screen of the explosion-proof mobile phone can be concavely covered. When the explosion-proof mobile phone falls, its screen and back plate do not directly contact the ground, which plays a buffering protection role. In addition, by arranging the anti-skid convex edges 23 on both sides of the anti-collision cover 2, it is convenient for the staff to hold it and use it, and it can also play a side protection role. When the explosion-proof mobile phone falls, the protruding anti-skid convex edges 23 are used to play a buffering protection role.

[0027] The heat dissipation substrate 3 includes two groups of heat dissipation plates 31 facing each other horizontally, and heat dissipation fins 32 are arranged inside the frames of the two groups of heat dissipation plates 31, and the two groups of heat dissipation plates 31 are connected by longitudinal heat-conducting fins 33, and the two sides of the plate frame of the longitudinal heat-conducting fins 33 are connected by multiple groups of transverse heat-conducting fins 34. The heat dissipation plates 31, the longitudinal heat-conducting fins 33, and the transverse heat-conducting fins 34 are all hollow structures. The interior of the heat dissipation substrate 3 is filled with a heat-conducting medium, and the filling amount of the heat-conducting medium is one-half of the capacity of the chamber of the heat dissipation substrate 3. The heat sink 31, the longitudinal heat-conducting fins 33, and the transverse heat-conducting fins 34 in the heat-dissipating substrate 3 are combined to form a hollow structure, and a heat-conducting medium is filled in the cavity thereof. The heat-conducting medium can be pure water, heat-conducting oil, and other media, which can allow the heat-conducting medium to flow freely in the heat-dissipating substrate 3 and flow disorderly with the movement and hand-holding of the staff, while taking away the heat generated by the explosion-proof mobile phone. At the same time, under the heat-conducting and heat-dissipating combination of the heat sink 31 and the heat-dissipating fins 32, the heat can be contacted with the outside air for heat exchange, thereby improving the heat dissipation efficiency of the explosion-proof mobile phone.

[0028] The longitudinal heat-conducting fins 33 and the transverse heat-conducting fins 34 are arranged in a cross-shaped symmetrical manner. The bottom plate of the back cover 1 is provided with an internal groove 11 for accommodating the heat dissipation substrate 3, and the heat dissipation substrate 3 and the back cover 1 are arranged flush with each other. By arranging the longitudinal heat-conducting fins 33 and the transverse heat-conducting fins 34 in the heat dissipation substrate 3 in a cross-shaped arrangement, on the one hand, it can play the role of a reinforcing rib to enhance the overall firmness and hardness of the back cover 1, and on the other hand, it can have uniform heat conduction performance and uniformly transfer the mechanical heat generated by the explosion-proof mobile phone.

[0029] The working principle of the utility model is as follows: based on the back cover 1 as the back shell structure of the explosion-proof mobile phone, the heat dissipation substrate 3 in the form of aluminum alloy is used to strengthen the back cover 1 internally, and the anti-collision cover 2 in the form of silicone material is elastically covered on the back cover 1, forming an internal support reinforcement and external anti-collision form;

[0030] During the assembly and use process, the upper and lower ends of the anti-collision cover 2 are provided with outwardly extending convex edges 22, so that the back plate and the screen of the explosion-proof mobile phone are concavely covered. When the explosion-proof mobile phone falls flat, the screen and the back plate do not directly contact the ground, which plays a buffering and protective role. When the explosion-proof mobile phone falls sideways, the protruding anti-slip convex edges 23 also play a buffering and protective role. The setting of the anti-slip convex edges 23 is convenient for the staff to hold and use.

[0031] Furthermore, by arranging the longitudinal heat-conducting fins 33 and the transverse heat-conducting fins 34 in the heat dissipation substrate 3 in a cross-shaped arrangement, they can play the role of reinforcing ribs, thereby enhancing the overall firmness and hardness of the back cover 1. Moreover, by arranging the heat-conducting substrate 3 as a hollow structure and filling the cavity with a heat-conducting medium, the heat-conducting medium can flow freely in the heat-conducting substrate 3, and flow disorderly with the movement and hand-holding of the staff, thereby taking away the heat generated by the explosion-proof mobile phone. At the same time, under the heat-conducting and heat-dissipating combination of the heat dissipation plate 31 and the heat-dissipating fins 32, the heat can be contacted with the outside air for heat exchange, thereby improving the heat dissipation efficiency of the explosion-proof mobile phone, so as to maintain the high-power signal transmission, communication and other operations of the explosion-proof mobile phone in the underground mine.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
