Description

Technical Field

[0001] This invention belongs to the field of tablet computer technology, specifically a low-power, high-heat-dissipation tablet computer. 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 (also known as digitizer technology) allows users to work with a stylus or digital pen instead of a traditional keyboard or mouse. Users can input through built-in handwriting recognition, an on-screen soft keyboard, voice recognition, or a physical keyboard (if the model is equipped with one).

[0003] Currently, tablet computers continuously generate heat during use, and they typically only dissipate heat through a few ventilation holes on the casing, resulting in low heat dissipation efficiency. When a tablet computer is used for a long time, its temperature rises rapidly, which not only affects the performance of the internal components but also increases the power consumption, making it inconvenient for users. Therefore, a low-power, high-heat-dissipation tablet computer is proposed. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the prior art, the present invention provides a low-power, high-heat-dissipation tablet computer, which effectively solves the problem that current tablet computers continuously generate heat during use, and that tablet computers generally only dissipate heat through a few heat dissipation holes on the casing, resulting in low heat dissipation efficiency. When the tablet computer is used for a long time, the temperature of the tablet computer will rise rapidly, which not only affects the working performance of the internal components of the tablet computer, but also easily increases the power consumption of the tablet computer, making it inconvenient for users.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a low-power, high-heat-dissipation tablet computer, comprising a display screen body and a computer casing, wherein the display screen body is installed in the computer casing, a circular opening is provided in the middle of the rear side of the computer casing, a blower aligned with the circular opening is fixedly installed on the inner side of the computer casing, two sets of symmetrically distributed air vents are provided on the rear side of the computer casing, a storage groove is provided on the lower side of the circular opening, a baffle is slidably installed in the storage groove, the upper end of the baffle can slide into the circular opening and block the circular opening, a positioning mechanism is also provided on the baffle, and a support mechanism is also provided on the rear side of the computer casing.

[0006] Preferably, the positioning mechanism includes two positioning blocks and two springs. Grooves are provided at the lower ends of both sides of the baffle. The two positioning blocks are slidably disposed in the two grooves respectively, and the two springs are also disposed in the two grooves respectively. Each spring is fixedly connected to the bottom of the groove and the positioning block respectively. The opposite ends of the two positioning blocks are arc-shaped. Two arc-shaped positioning grooves are provided on the left and right side walls of the storage groove for the positioning blocks to slide into. Two of the arc-shaped positioning grooves are located at the lower ends of the left and right side walls of the storage groove, and the other two arc-shaped positioning grooves are located in the middle of the left and right side walls of the storage groove.

[0007] Preferably, the baffle has anti-slip texture on its upper surface.

[0008] Preferably, a first dustproof net is fixedly installed on the outer side of the circular opening, and a second dustproof net is fixedly installed in each of the air outlets.

[0009] Preferably, the support mechanism includes two support rods. Two vertically arranged strip slots are opened on the rear side of the computer housing. The two support rods are respectively arranged in the two strip slots. The upper ends of the left and right sides of the rod wall of each support rod are rotatably connected to the side wall of the strip slot through a rotating shaft. A permanent magnet is fixedly embedded in the bottom of each strip slot. A metal block is fixedly embedded in the side of the rod wall of each support rod near the permanent magnet.

[0010] Preferably, each of the rotating shafts is fixedly fitted with a damping sleeve, and the two ends of the damping sleeve are respectively tightly abutted against the side wall of the strip groove and the support rod and can be slidably arranged.

[0011] Preferably, the outer walls of the computer casing are fixedly fitted with annular protective pads.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. When in use, pull the baffle down to retract it into the storage slot, open the round opening, and start the blower. The blower blows air into the computer casing, thus cooling the internal components of the tablet. Heat is dissipated through the two sets of air outlets, improving heat dissipation efficiency. When the blower is not needed, stop its rotation and pull the baffle up to block the round opening. Two positioning blocks and multiple arc-shaped positioning slots are used. When the baffle is pulled up to block the opening, the two positioning blocks engage with the two upper arc-shaped positioning slots under the action of two springs. When the baffle is retracted into the storage slot, the two positioning blocks engage with the two lower arc-shaped positioning slots under the action of two springs. This prevents the baffle from sliding freely without manual pushing. This device accelerates heat dissipation inside the tablet, improving heat dissipation and preventing the tablet from overheating, which could affect its performance and increase power consumption, making it easier for users to operate.

[0021] This invention provides, for example Figure 1-5The illustrated low-power, high-heat-dissipation tablet computer includes a display screen body 1 and a computer casing 2. The display screen body 1 is installed in the computer casing 2. A circular opening is provided in the middle of the rear side of the computer casing 2. A blower 3 aligned with the circular opening is fixedly installed on the inner side of the computer casing 2. Two sets of symmetrically distributed air vents are provided on the rear side of the computer casing 2. A storage groove is provided on the lower side of the circular opening. A baffle 4 is slidably installed in the storage groove. The upper end of the baffle 4 can slide into the circular opening and block the circular opening. A positioning mechanism is also provided on the baffle 4. A support mechanism is also provided on the rear side of the computer casing 2.

[0022] like Figure 3 As shown, the positioning mechanism includes two positioning blocks 5 and two springs 6. Grooves are provided at the lower ends of both sides of the baffle 4. The two positioning blocks 5 are slidably disposed in the two grooves respectively, and the two springs 6 are also disposed in the two grooves respectively. Each spring 6 is fixedly connected to the bottom of the groove and the positioning block 5 respectively. The opposite ends of the two positioning blocks 5 are arc-shaped. Two arc-shaped positioning grooves are provided on the left and right side walls of the storage groove, which allow the positioning blocks 5 to slide into. Two arc-shaped positioning grooves are located at the lower ends of the left and right side walls of the storage groove, and the other two arc-shaped positioning grooves are located in the middle of the left and right side walls of the storage groove. When the baffle 4 is pulled upward to block the round opening, the two positioning blocks 5 will be locked into the two upper arc-shaped positioning grooves under the action of the two springs 6. When the baffle 4 is stored in the storage groove, the two positioning blocks 5 will be able to enter the two lower arc-shaped positioning grooves under the action of the two springs 6, which can prevent the baffle 4 from sliding freely when not pushed by human force.

[0023] like Figure 3 As shown, the surface of the baffle 4 is provided with anti-slip texture to facilitate people to pull the baffle 4 to move vertically.

[0024] like Figure 2 As shown, a first dustproof mesh 7 is fixedly installed on the outer side of the round opening, and a second dustproof mesh 8 is fixedly installed in each air outlet to prevent dust from entering the computer casing 2 through the round opening and the air outlet.

[0025] like Figure 2 and Figure 5As shown, the support mechanism includes two support rods 9. Two vertically arranged strip slots are opened on the rear side of the computer casing 2. The two support rods 9 are respectively set in the two strip slots, and the upper ends of the left and right sides of each support rod 9 are rotatably connected to the side wall of the strip slot through a pivot. A permanent magnet 10 is fixedly embedded in the bottom of each strip slot, and a metal block 11 is fixedly embedded in the side of each support rod 9 near the permanent magnet 10. When it is necessary to support the tablet computer, the two support rods 9 can be rotated out of the two vertical slots so that the two support rods 9 are perpendicular to the tablet computer, thereby supporting the tablet computer. It can support the tablet computer when it is placed horizontally or vertically. When the support rod 9 is rotated into the vertical slot, the permanent magnet 10 will attract the metal block 11 to prevent the support rod 9 from automatically rotating out of the vertical slot.

[0026] like Figure 5 As shown, each rotating shaft is fixedly fitted with a damping sleeve 12. The two ends of the damping sleeve 12 are tightly abutted against the side wall of the strip groove and the support rod 9 respectively and can be slidably set, which can improve the friction between the support rod 9 and the side wall of the strip groove and prevent the support rod 9 from rotating freely.

[0027] like Figure 1 and Figure 2 As shown, the computer casing 2 has annular protective pads 13 fixedly fitted on its four outer side walls, which can improve the protection of the four side walls of the computer casing 2 and prevent the four side walls of the computer casing 2 from being damaged by impact.

[0028] The working principle of this invention is as follows: In use, the baffle 4 is pulled down to retract into the storage slot, opening the round opening. The blower 3 is then activated, blowing air into the computer casing 2, thus cooling the internal components of the tablet. Heat is dissipated through the two sets of air outlets, improving heat dissipation efficiency. When the blower 3 is no longer needed, it is stopped, and the baffle 4 is pulled up to block the round opening. Using two positioning blocks 5 and multiple arc-shaped positioning slots, when the baffle 4 is pulled up to block the round opening, the two positioning blocks 5 are engaged in the two upper arc-shaped positioning slots by the two springs 6. When the baffle 4 is retracted into the storage slot, the two positioning blocks 5 are engaged in the two lower arc-shaped positioning slots by the two springs 6. This prevents the baffle 4 from sliding freely without manual pushing. This device accelerates heat dissipation within the tablet, improving the cooling effect and preventing the tablet from overheating and affecting its performance and power consumption, making it easier for users to operate.
