Description

Technical Field

[0001] The utility model relates to the field of plastic casings, in particular to a high-temperature resistant plastic casing. Background Art

[0002] Plastic casings play an extremely important role in the modern industrial and consumer electronics fields. These plastic materials have characteristics such as being lightweight, durable, and cost-effective, and gradually replace traditional metal and glass casings to become the preferred materials in many fields.

[0003] Existing plastic casings are usually made of a mixture of one or more materials. When applied in a high-temperature environment, the heat inside is difficult to dissipate, and large losses will occur inside after long-term use. Moreover, they generally do not have good buffering ability and surface strength. When in contact with electronic devices, surface wear is likely to occur. Once cracking occurs, it will affect their heat resistance. At the same time, existing plastic casings are often fixedly connected to electronic devices through glue, which is not easy to disassemble, and forced disassembly will also cause damage to the plastic casings themselves.

[0004] Therefore, those skilled in the art provide a high-temperature resistant plastic casing to solve the problems raised in the above background art. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and a high-temperature resistant plastic casing is proposed. The plastic casing conducts heat through a multi-layer structure inside to connect the temperature of the electronic device and the temperature inside the casing main body with an external heat sink. By setting a primary filter layer, the influence of dust is reduced and it can be cleaned for recycling. The plastic casing does not need to use glue for fixation, is convenient for disassembly and installation, and is also applicable to electronic devices of different sizes.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-temperature resistant plastic casing, including a casing main body. A glue layer is provided at the lower end of the casing main body. An external heat conduction layer is fixedly provided at the lower end of the glue layer. An external coating is coated at the lower end of the external heat conduction layer. An internal heat conduction layer penetrates through the inside of the casing main body. A plurality of reinforcing ribs penetrate through the inside of the internal heat conduction layer. A heat conduction sheet is sleeved around the upper part of the internal heat conduction layer. A plurality of heat sinks are fixedly provided at the upper end of the casing main body. A primary filter layer is filled at the upper part inside the casing main body. A plurality of small holes are opened at the upper end of the casing main body;

[0007] A fixing body is fixedly arranged at the lower end of the plastic shell main body. A sliding groove is formed at the edge of the lower end of the fixing body. Pulleys are arranged at the inner walls of the sliding groove at the corners. A plurality of sliding blocks are clamped and slidably arranged in the sliding groove. A rope is arranged between the plurality of sliding blocks. Protrusions are fixedly arranged at the centers of the inner and outer walls of the sliding groove. Rubber bands are arranged between the plurality of protrusions and the sliding blocks on the same side. An electronic device is arranged at the lower end of the plastic shell main body;

[0008] Through the above technical solution, the plastic shell main body is made of a material with high heat resistance. Heat is conducted to the outside through the outer heat conduction layer, the inner heat conduction layer and the heat sink for cooling. The inner heat conduction layer and the heat conduction sheet can conduct heat better. By coating the outer coating on the surface of the outer heat conduction layer, its strength can be enhanced to ensure the surface state of the lower end of the plastic shell main body. The buffer effect can be effectively achieved through the reinforcing ribs arranged inside and the wavy design at the upper end of the plastic shell main body, reducing the friction and impact loss between the internal layers. By arranging the fixing body, after the electronic device is placed in its groove, the heated side is in contact with the plastic shell main body. Fixing only requires pushing any one of the sliding blocks, and the remaining sliding blocks can be driven to move through the rope. Affected by the elastic rebound of the rubber band, the plurality of sliding blocks rebound towards the center of the side where they are located. At this time, the sliding blocks can be clamped around the electronic device to form a fixation.

[0009] Further, the materials of the plurality of heat sinks are all aluminum. The lower ends of the plurality of heat sinks are all connected to the inner heat conduction layer. The inner heat conduction layer is heat-conducting silica gel;

[0010] Through the above technical solution, aluminum, as the material of the heat sink, has the characteristics of good heat conduction, light weight, easy processing and corrosion resistance.

[0011] Further, the plurality of small holes communicate with the primary filter layer. The primary filter layer is a polyurethane dust-proof filter cotton;

[0012] Through the above technical solution, the polyurethane dust-proof filter cotton has good dust-proof performance. Cooperating with the small holes, it improves the heat dissipation ability, and the filter cotton is high-temperature resistant, easy to clean and can be reused.

[0013] Further, the material of the heat conduction sheet is carbon fiber, and the material of the outer heat conduction layer is polysulfone plastic;

[0014] Through the above technical solution, carbon fiber has very high heat conduction performance. Placing it inside can conduct heat better, and the soft filling inside can prevent it from directly bearing excessive pressure. Polysulfone plastic has high strength and heat resistance, and at the same time has excellent electrical insulation properties, which is suitable for the outer shell of electronic components.

[0015] Furthermore, the adhesive layer is made of polyimide coating adhesive;

[0017] Furthermore, the outer coating is made of graphene composite coating;

[0018] Through the above technical solution, the graphene composite coating can ensure the good working state of the outer heat conduction layer, ensure its heat conduction and heat resistance performance, and effectively improve the surface strength.

[0019] Furthermore, the rubber band has great elasticity, the rope is wound around a plurality of pulleys, and the rope is in a taut state;

[0020] Through the above technical solution, after the sliding block moves, it can rebound through the elasticity of the rubber band to play a role in fixing on one side of the electronic device. By the rope in a taut state, the purpose of driving any one sliding block to drive the remaining sliding blocks can be achieved.

[0021] Furthermore, the fixing body and the main body of the rubber shell form a groove. When the electronic device is placed in this groove, its surface contacts the outer coating. The main body of the rubber shell is made of polyether ether ketone resin;
