Description

Technical Field

[0001] This utility model relates to the field of tablet computer accessories technology, and in particular to a tablet computer protective case. Background Technology

[0002] Tablet cases are used to protect tablets. Traditional tablet cases only provide basic protection and have limited functionality. Tablets generate a lot of heat after prolonged use. Typical tablet cases cover the back of the tablet, making it difficult for the heat to dissipate, causing the internal temperature of the tablet to become too high, which in turn affects the smooth operation of the device. Utility Model Content

[0003] Based on this, in order to overcome the shortcomings of the existing technology, this utility model provides a tablet computer protective case. Through the staggered horizontal air ducts, vertical air ducts and circular air ducts, a chimney effect is formed during use, hot air flows upward and external cold air enters from the side, forming an automated airflow interaction, thereby achieving a rapid heat dissipation and cooling effect for the tablet computer.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a tablet computer protective cover, including a main body, an assembly cavity for assembling a tablet computer is opened at the front end of the main body, and a transverse air duct and a longitudinal air duct are opened in the inner wall of the assembly cavity, which are intersected and connected through the wall of the main body. A circular air duct connecting the transverse air duct and the longitudinal air duct is also opened in the middle of the inner wall of the assembly cavity.

[0005] Traditional tablet cases provide some protection by covering the back and four sides of the tablet. Some tablet cases on the market use a metal plate, such as an aluminum plate, on the back to facilitate heat dissipation. This plate transfers heat from the tablet's back panel to the outside air. However, tablets generally have their own internal heat transfer structure to dissipate heat generated by internal components. The heat is then dissipated to the outside air through the back panel. A tablet case with a thermally conductive metal back panel simply adds an extra layer of heat transfer. Because the case creates a sealed cavity, its heat dissipation effect is not as strong as the tablet's own heat dissipation.

[0006] When this invention is in use, such as when the tablet computer is used horizontally, the heat generated on the back of the tablet computer raises the temperature of the air inside the main body. The high temperature rises and can be discharged from the top of the vertical air duct. Then, under the action of external pressure, external air enters the main body from the openings at both ends of the horizontal air duct, forming a self-circulating air-cooling system, i.e., the chimney effect, which continuously dissipates heat from the back of the tablet computer. In addition, the circular air duct increases the contact area between the air duct and the back of the tablet computer, which can achieve heat dissipation and cooling effect more quickly. When the tablet computer is used vertically, the heat dissipation and cooling principle is the same as above, and will not be described again.

[0007] Preferably, an assembly groove is provided on the back of the main body, and a support frame assembly is provided in the assembly groove. The support frame assembly includes a base plate and a support plate. The lower end of the base plate is rotatably connected to the lower end of the assembly groove, and the upper end of the base plate is rotatably connected to the upper end of the support plate. Limiting grooves are provided at equal intervals on the upper end of the inner wall of the assembly groove. A first magnet is embedded in the inner wall of the assembly groove at the lower end of the limiting groove, and a second magnet is embedded on the back of the support plate. When the support plate is stored, the first magnet and the second magnet are in corresponding positions and magnetically attracted to each other. The lower end of the support plate can be rotated to limit and cooperate with the limiting groove.

[0008] Preferably, the upper end of the assembly slot is provided with an arc notch.

[0009] When the support frame assembly is in its stored state, the magnetic attraction between the first and second magnets allows for concealed storage. In use, the user's finger rotates the base plate and support plate through the arc notch, releasing the magnetic attraction between the first and second magnets. Rotating the base plate and support plate opens the mounting, and the lower end of the support plate engages with the limiting groove to support the tablet computer and adjust the support angle.

[0010] Preferably, cushioning pads are fixedly bonded to the four corners of the assembly cavity to provide cushioning and anti-collision protection.

[0011] The beneficial effects of this utility model are: By combining horizontal and vertical air ducts that run through the main body wall and are arranged in an interlaced manner, a chimney effect is formed. The heat emitted from the back of the tablet computer raises the temperature of the air inside the main body and is discharged from the top of the air duct. Meanwhile, external cold air enters the main body from the left and right sides of the air duct, forming a self-circulating air-cooling system that continuously dissipates heat and cools the body. The tablet computer is supported by a hidden support frame component design, and different support angles can be adjusted for easy use. Attached Figure Description

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] like Figures 1 to 4 As shown, this utility model provides a tablet computer protective case, including a main body 1. The front end of the main body 1 has an assembly cavity for assembling a tablet computer. The inner wall of the assembly cavity has a transverse air duct 10 and a longitudinal air duct 11 that are intersected and connected through the wall of the main body 1. The middle part of the inner wall of the assembly cavity also has an annular air duct 12 that connects the transverse air duct 10 and the longitudinal air duct 11.

[0018] Traditional tablet cases provide some protection by covering the back and four sides of the tablet. Some tablet cases on the market use a metal plate, such as an aluminum plate, on the back to facilitate heat dissipation. This plate transfers heat from the tablet's back panel to the outside air. However, tablets generally have their own internal heat transfer structure to dissipate heat generated by internal components. The heat is then dissipated to the outside air through the back panel. A tablet case with a thermally conductive metal back panel simply adds an extra layer of heat transfer. Because the case creates a sealed cavity, its heat dissipation effect is not as strong as the tablet's own heat dissipation.

[0019] When this invention is in use, such as when the tablet computer is used horizontally, the heat generated on the back of the tablet computer raises the temperature of the air inside the main body 1. The high temperature rises and can be discharged from the top of the vertical air duct 11. Then, under the action of external pressure, external air enters the interior of the main body 1 from the openings at both ends of the horizontal air duct 10, forming a self-circulating air-cooling system, i.e., the chimney effect, to continuously dissipate heat from the back of the tablet computer. In addition, the circular air duct 12 increases the contact area between the air duct and the back of the tablet computer, which can achieve heat dissipation more quickly and achieve a heat dissipation and cooling effect. When the tablet computer is used vertically, the heat dissipation and cooling principle is the same as above, and will not be described again.

[0020] Furthermore, the back of the main body 1 is provided with an assembly groove 13, and a support frame assembly 2 is provided in the assembly groove 13. The support frame assembly 2 includes a base plate 20 and a support plate 21. The lower end of the base plate 20 is rotatably connected to the lower end of the assembly groove 13, and the upper end of the base plate 20 is rotatably connected to the upper end of the support plate 21. Limiting grooves 131 are provided at equal intervals on the upper end of the inner wall of the assembly groove 13. A first magnet 130 is embedded in the inner wall of the assembly groove 13 at the lower end of the limiting groove 131. A second magnet 210 is embedded in the back of the support plate 21. When the support plate 21 is stored, the first magnet 130 and the second magnet 210 are in corresponding positions and magnetically attracted to each other. The lower end of the support plate 21 can be rotated to limit and cooperate with the limiting groove 131.

[0021] Furthermore, the upper end of the assembly slot 13 is provided with an arc notch 132.

[0022] When the support frame assembly 2 is in the storage state, the magnetic attraction between the first magnet 130 and the second magnet 210 enables the support frame assembly 2 to be hidden. When in use, the finger drives the base plate 20 and the support plate 21 to rotate through the arc notch 132, thereby releasing the magnetic attraction between the first magnet 130 and the second magnet 210. The base plate 20 and the support plate 21 are opened by rotating. The lower end of the support plate 21 is matched with the limiting groove 131 to achieve the support of the tablet computer and the adjustment of different support angles.

[0023] Furthermore, cushioning pads are fixedly bonded to the four corners of the assembly cavity to provide cushioning and impact protection.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
