Description

Technical Field

[0001] This utility model relates to the field of tablet computer technology, specifically to a dustproof tablet computer with high heat dissipation. Background Technology

[0002] Tablet computers, also known as portable computers, are small, portable personal computers that use a touchscreen as their basic input device. The touchscreen allows users to perform tasks using a stylus or digital pen instead of a traditional keyboard or mouse. Users can input data through built-in handwriting recognition, an on-screen soft keyboard, voice recognition, or a physical keyboard.

[0003] When a tablet is not in use, it is usually placed on a table. Dust particles in the air naturally fall and adhere to the surface of the heat dissipation vents due to gravity or slight air movement. In particular, the heat dissipation vents are often designed with fine grilles or slits, and their uneven structure easily becomes a trapping point for dust. Tiny dust particles get stuck in the gaps and gradually accumulate, eventually blocking the heat dissipation channels and hindering airflow. This prevents the heat generated by the device from being dissipated in time, ultimately greatly reducing the heat dissipation effect. At the same time, in order to connect to external devices, tablets have ports, most of which are exposed. External dust can easily enter the ports, thus affecting the normal use of the tablet. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a dustproof tablet computer with high heat dissipation. It has a simple structure, effectively prevents dust, improves heat dissipation efficiency, delays the aging of internal components, and extends service life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-heat-dissipation, dustproof tablet computer includes a tablet computer body. The outer shell of the tablet computer body is composed of a front shell and a rear shell. A display screen is provided on the front shell. The front shell and the rear shell are fixedly connected together by fixing screws. A surrounding plate is provided on the inner edge of the rear shell. The surrounding plate has several heat dissipation slots and clearance slots, which are arranged alternately. A heat-conducting plate is provided inside the tablet computer body. The heat-conducting plate is in close contact with the internal heat-generating components and extends to the heat dissipation slots. Heat dissipation fins and dustproof mesh are arranged sequentially on the outer side of the heat dissipation slots. The heat dissipation fins are connected to the heat-conducting plate. The outer edges of the front shell and the rear shell extend outward to form a receiving cavity. The key switches and external ports of the tablet computer body can pass through the clearance slots and be placed in the receiving cavity. A removable sealing strip is installed at the opening of the receiving cavity.

[0007] Preferably, both ends of the sealing strip are provided with locking posts, and the surrounding plate is provided with locking grooves corresponding to the locking posts. The locking posts are inserted into the locking grooves, so that the sealing strip can be detachably installed at the opening of the receiving cavity to form a sealed space.

[0008] Preferably, the inner wall of the sealing strip is provided with a receiving groove adapted to the push-button switch and a sealing plug adapted to the external port.

[0009] Preferably, each of the four corners of the receiving cavity is provided with an arc-shaped positioning plate.

[0010] Preferably, a positioning hole is provided between the arc-shaped positioning plate and the surrounding plate, and a positioning post corresponding to the positioning hole is provided on the front shell.

[0011] The beneficial effects of this invention are as follows: A surrounding plate is provided on the inner edge of the rear shell, which enhances the structural strength of the rear shell and reduces the risk of deformation during drops or crushing. The surrounding plate has several heat dissipation slots and clearance slots arranged alternately. A heat-conducting plate is installed inside the tablet body, closely fitting the internal heating elements and extending into the heat dissipation slots. Heat dissipation fins and a dust filter are sequentially arranged on the outer side of the heat dissipation slots. The heat dissipation fins are connected to the heat-conducting plate, enabling them to absorb heat immediately and reduce the time heat accumulates internally. Simultaneously, the multi-plate structure of the heat dissipation fins significantly increases the contact area with air, quickly dissipating the heat transferred by the heat-conducting plate to the outside. The dust filter effectively blocks dust, lint, and other impurities from the air from entering the device, preventing dust from adhering to the heat-conducting plate, heat sink fins, or heat-generating components, thus improving heat dissipation efficiency, delaying the aging of internal components, and extending service life. The outer edges of the front and rear shells extend outward to form a receiving cavity. The tablet's main body buttons, switches, and external ports can pass through the recessed slots and be placed inside the receiving cavity. A removable sealing strip is installed at the opening of the receiving cavity. The buttons, switches, and external ports are housed within the receiving cavity. With the sealing strip, dust and liquid intrusion into the tablet's main body can be reduced, effectively preventing dust and reducing damage to the buttons, switches, and external interfaces caused by external forces, thus reducing the frequency of maintenance or replacement.

Detailed Implementation

[0015] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments:

[0016] This embodiment: as follows Figure 1-2 As shown, a high heat dissipation dustproof tablet computer includes a tablet computer body 10. The outer shell of the tablet computer body 10 is composed of a front shell 20 and a rear shell 30. A display screen 21 is provided on the front shell 20. The front shell 20 and the rear shell 30 are fixedly connected together by fixing screws, which makes the connection stable and easy to disassemble and repair.

[0017] A surrounding plate 31 is provided on the inner edge of the rear shell 30. The surrounding plate 31 can enhance the structural strength of the rear shell 30 and reduce the risk of deformation when the device is dropped or squeezed. The surrounding plate 31 is provided with several heat dissipation channels 32 and clearance channels 33, which are arranged alternately. A heat-conducting plate 11 is provided inside the tablet body 10. The heat-conducting plate 11 is closely attached to the internal heat-generating elements and extends to the heat dissipation channels 32. Heat dissipation fins and dustproof nets 35 are arranged in sequence on the outer side of the heat dissipation channels 32. The heat dissipation fins are connected to the heat-conducting plate 11 and can absorb heat in time, reducing the time of heat accumulation inside. At the same time, the heat dissipation fins have a multi-piece structure, which greatly increases the contact area with air and can quickly dissipate the heat transferred by the heat-conducting plate 11 to the outside. The dustproof nets 35 can effectively block dust, lint and other impurities in the air from entering the device, preventing dust from adhering to the heat-conducting plate 11, heat dissipation fins or heat-generating elements, improving heat dissipation efficiency, delaying the aging of internal components and extending service life.

[0018] The outer edges of the front shell 20 and the rear shell 30 extend outward to form a receiving cavity 34. The button switch 12 and external port 13 of the tablet body 10 can pass through the clearance groove 33 and be placed in the receiving cavity 34. Each of the four corners of the receiving cavity 34 is provided with an arc-shaped positioning plate 37. A positioning hole is provided between the arc-shaped positioning plate 37 and the surrounding plate 31. The front shell 20 is provided with a positioning post 38 corresponding to the positioning hole to achieve quick positioning and assembly and ensure positioning accuracy. A sealing strip 36 is installed at the opening of the receiving cavity 34. Both ends of the sealing strip 36 are provided with a locking post 361. The locking post 361 is made of silicone material. The surrounding plate 31 is provided with a locking groove 311 corresponding to the locking post 361. The diameter of the locking groove 311 is slightly smaller than the diameter of the locking post 361. The locking post 361 undergoes elastic deformation due to compression. Thus, it smoothly enters the slot 311. Due to the properties of the silicone material, it recovers its original shape through its own elasticity and tightly fits the inner wall of the slot 311, forming a firm snap-fit ​​effect. This allows the sealing strip 36 to be detachably installed at the opening of the receiving cavity 34, forming a sealed space. The button switch 12 and the external port 13 are housed in the receiving cavity 34. The inner wall of the sealing strip 36 has a receiving groove 362 that is adapted to the button switch 12, which wraps the button switch 12, and a sealing plug 363 that is adapted to the external port 13, which seals the external port 13. With the sealing strip 36, dust and liquid can be reduced from entering the tablet computer body 10, which can effectively prevent dust. At the same time, it can reduce the damage to the button switch 12 and the external interface caused by external force, and reduce the frequency of maintenance or replacement.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
