[0005] Aiming at the deficiencies of the prior art, the present invention provides a portable desktop computer, which solves the problems put forward in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A portable desktop computer includes a chassis body, and further includes a pressure prevention device and a heat dissipation device; wherein, a button is slidably installed on the surface of the chassis body, a power supply is fixedly installed inside the chassis body, and the button is electrically connected to the power supply; wherein, the pressure prevention device includes a support base, a fixed bolt, a push plate and a stopper. When the chassis body is subjected to external pressure, the chassis body moves downward, causing the fixed bolt inside the support base to move upward. The upward movement of the fixed bolt drives the push plate to move upward. The support base is fixedly installed at the bottom of the chassis body, the fixed bolt is slidably installed inside the support base, the push plate is slidably installed on the inner wall of the chassis body, a first chute is formed on the surface of the inner wall of the chassis body, the stopper is slidably installed inside the first chute, one end of the stopper close to the push plate is formed as a first arc surface, the push plate and the inner wall of the chassis body are fixedly connected by a first elastic telescopic rod, and the stopper and the inner wall of the first chute are fixedly connected by a second elastic telescopic rod. The upward movement of the push plate contacts and squeezes the stopper to move, and the reset of the stopper after movement can effectively release the pressure on the chassis body, converting the rigid connection into an elastic connection, and avoiding the deformation of the chassis body under the action of pressure.

[0007] According to the above technical solution, a lifting rod is fixedly installed above the push plate, a support rod is slidably installed on the inner wall of the chassis body, a first clockwork spring is arranged between the support rod and the inner wall of the chassis body, a cross bar is slidably installed on the surface of the inner wall of the chassis body, a connecting rod is hinged on the surface of the cross bar, and one end of the connecting rod far from the cross bar is hinged to the support rod. One end of the cross bar close to the lifting rod is formed as a first inclined plane. The movement of the connecting rod drives the support rod to move away from each other. The movement of the support rod away from each other can provide additional support for the inner wall of the chassis body, further avoiding the deformation of the chassis body under the action of external force, thereby causing damage to the internal electronic devices and reducing the subsequent maintenance cost.

[0008] According to the above technical solution, the heat dissipation device includes a mounting plate, a hydraulic motor, a push rod, an exhaust fan, a filter plate and a baffle. When the power supply is started, it drives the exhaust fan and the hydraulic motor to start. The output end of the hydraulic motor moves to drive the push rod to move, and the movement of the push rod drives the baffle to move. The mounting plate is fixedly installed inside the chassis body. The hydraulic motor is fixedly installed above the mounting plate. The push rod is fixedly installed at the output end of the hydraulic motor. A second chute is formed on the surface of the chassis body. The exhaust fan is fixedly installed inside the second chute. The filter plate is fixedly installed inside the second chute. The baffle is fixedly installed at one end of the push rod away from the hydraulic motor. The hydraulic motor is electrically connected to the power supply, and the exhaust fan is electrically connected to the power supply. When the baffle moves, it opens the outlet of the second chute on the surface of the chassis body. At the same time, when the exhaust fan starts, it can discharge the heat inside the chassis body for heat dissipation, maintaining the stability of the temperature inside the chassis body. At the same time, it can effectively prevent foreign objects from entering the inside of the chassis body through the filter plate during the movement of the chassis body.

[0009] According to the above technical solution, a connecting plate is fixedly installed at one end of the baffle close to the chassis body. The connecting plate slidably penetrates the inner and outer walls of the chassis body. A second clockwork spring is arranged between the connecting plate and the chassis body. The movement of the baffle drives the connecting plate to slide on the surface of the second chute, assisting the movement of the baffle, improving the stability of the baffle during movement, and reducing subsequent maintenance costs.

[0010] According to the above technical solution, it further includes a scraping device and a limiting device. The scraping device includes a receiving rod, a sleeve, a telescopic elastic rod, a scraping rod, a receiving shaft and a sleeve rod. The movement of the baffle drives the receiving rod to move, the movement of the receiving rod drives the sleeve to move, the movement of the sleeve drives the telescopic elastic rod to move, and the movement of the telescopic elastic rod drives the sleeve rod to move. A third chute is formed on the surface of the baffle. The receiving rod is fixedly installed inside the third chute. The sleeve is rotatably installed on the surface of the receiving rod. The telescopic elastic rod is fixedly installed on the surface of the sleeve. The scraping rod is slidably installed on the surface of the filter plate. A fourth chute is formed on the surface of the scraping rod. The receiving shaft is fixedly installed inside the fourth chute. The sleeve rod is rotatably installed on the surface of the receiving shaft. The free end of the telescopic elastic rod is fixedly connected to the sleeve rod. A brush is arranged on the surface of the scraping rod. The movement of the sleeve rod drives the receiving shaft to move, and the movement of the receiving shaft drives the scraping rod to move on the surface of the filter plate, so that the brush on the surface of the scraping rod scrapes the dust and foreign objects on the surface of the filter plate, preventing foreign objects and dust from accumulating on the surface of the filter plate and affecting the heat dissipation effect.

[0011] According to the above technical solution, a rubber plate is fixedly installed at the bottom of the inner wall of the second chute. The rubber plate is slidably connected to the scraping rod. When the scraping rod moves and contacts the rubber plate, static electricity is generated. The static electricity can effectively make the scraping rod adsorb the dust and foreign objects scraped from the surface of the filter plate, avoiding the flying of dust and foreign objects and affecting the scraping effect. When the work stops, the baffle resets so that the scraping rod contacts the baffle, releasing the static electricity and discharging the adsorbed foreign objects and dust, preventing foreign objects and dust from entering the interior of the chassis body and reducing the subsequent maintenance cost.

[0012] According to the above technical solution, the limiting device includes a sliding block, a fixed rod, a grip strap, a pulling plate, a limiting plate and a limiting rod. By lifting the grip strap upward, the upward movement of the grip strap drives the fixed rod to move, and the movement of the fixed rod drives the sliding blocks to move towards each other. A fifth chute is opened above the chassis body, and the sliding blocks are slidably installed inside the fifth chute. The fixed rod is fixedly installed above the sliding blocks. The grip strap is fixedly installed on the surface of the fixed rod. The pulling plate is fixedly installed on the surface of the sliding blocks. The limiting plate is slidably installed above the chassis body. The limiting rod is fixedly installed at one end of the limiting plate away from the sliding blocks. The movement of the limiting rod contacts and presses the limiting plate to move, and the movement of the limiting plate limits the baffle, avoiding the baffle from shaking and opening the entrance of the second chute during the movement of the chassis body, improving the sealing effect and preventing foreign objects from entering the interior of the chassis body and damaging the internal electrical components.

[0013] According to the above technical solution, sliding blocks are arranged on both the left and right sides of the grip strap. The two sliding blocks are fixedly connected by a third elastic telescopic rod. A third clockwork spring is arranged between the limiting plate and the chassis body. After releasing the grip strap, the sliding blocks reset under the action of the third elastic telescopic rod, enabling the limiting plate to release the limit on the baffle, facilitating the use of the device.

[0014] The present invention provides a portable desktop computer, which has the following beneficial effects: (1) For this portable desktop computer, when the chassis body is externally squeezed, the chassis body squeezes the stopper to move under the action of the fixed bolt and the push plate, realizing the release of the pressure received by the chassis body, converting the rigid connection into an elastic connection, avoiding the deformation of the chassis body under the action of the pressure. At the same time, the push plate continues to move to drive the connecting rod and the support rod to move through the lifting rod and the cross bar, providing additional support for the inner wall of the chassis body, further avoiding the deformation of the chassis body under the action of external force and damaging the internal electronic components, and reducing the subsequent maintenance cost.

[0015] (2)The portable desktop computer starts the exhaust fan and the hydraulic motor through buttons and power supply, so that when the machine is working, the hydraulic motor drives the baffle to move through the push rod to open the outlet of the second chute, dissipate heat from the inside of the chassis body, maintain the stability of the temperature inside the chassis body, and effectively prevent foreign objects from entering the inside of the chassis body through the filter plate during the movement of the chassis body, thus causing damage to the internal electronic components, reducing the subsequent maintenance cost. At the same time, the movement of the baffle can improve its stability during movement through the connecting plate, reducing the subsequent maintenance cost.

[0016] (3)In the portable desktop computer, the movement of the baffle drives the telescopic spring rod and the sleeve rod to move through the receiving rod and the sleeve, and the movement of the sleeve rod drives the scraping rod to move on the surface of the filter plate through the receiving shaft, scraping off the dust and foreign objects on the surface of the filter plate, preventing foreign objects and dust from accumulating on the surface of the filter plate and affecting the heat dissipation effect. At the same time, the scraping rod moves to contact the rubber plate and generates static electricity, which can effectively adsorb the dust and foreign objects scraped off from the surface of the filter plate, prevent foreign objects and dust from entering the inside of the chassis body, and reduce the subsequent maintenance cost.

[0017] (4)In the portable desktop computer, the movement of the grip band and the fixed rod drives the sliding block and the pull plate to move, and the movement of the pull plate drives the limiting rod to move into contact with and squeeze the limiting plate to move, and the movement of the limiting plate limits the baffle, preventing the baffle from shaking and opening the inlet of the second chute during the movement of the chassis body, improving the sealing effect. After loosening the grip band, the sliding block resets under the action of the elastic telescopic rod three, causing the limiting plate to release the limit on the baffle, facilitating the use of the device.

When the main body of the chassis 1 is subjected to external pressure, the main body of the chassis 1 moves downward, causing the fixed pin 42 inside the support seat 41 to move upward. The upward movement of the fixed pin 42 drives the push plate 43 to move upward. The support seat 41 is fixedly installed at the bottom of the main body of the chassis 1, the fixed pin 42 is slidably installed inside the support seat 41, the push plate 43 is slidably installed on the inner wall of the main body of the chassis 1, a chute 1 is provided on the inner wall surface of the main body of the chassis 1, the stopper 44 is slidably installed inside the chute 1, and the end of the stopper 44 close to the push plate 43 is provided with a first arc surface. The push plate 43 is fixedly connected to the inner wall of the main body of the chassis 1 through a first elastic telescopic rod, and the stopper 44 is fixedly connected to the inner wall of the chute 1 through a second elastic telescopic rod. The upward movement of the push plate 43 contacts and squeezes the stopper 44 to move, and the reset of the stopper 44 after movement can effectively release the pressure on the main body of the chassis 1, converting the rigid connection into an elastic connection, and avoiding deformation of the main body of the chassis 1 under the action of pressure.

[0022] Above the push plate 43, a lifting rod 45 is fixedly installed. A support rod 46 is slidably installed on the inner wall of the chassis body 1. A first clockwork spring is arranged between the support rod 46 and the inner wall of the chassis body 1. A cross bar 47 is slidably installed on the surface of the inner wall of the chassis body 1.

[0023] The heat dissipation device includes a mounting plate 51, a hydraulic motor 52, a push rod 53, an exhaust fan 54, a filter plate 55 and a baffle 56. When the power supply 3 is started, it drives the exhaust fan 54 and the hydraulic motor 52 to start. The output end of the hydraulic motor 52 moves to drive the push rod 53 to move.

The baffle 56 is fixedly installed at the end of the push rod 53 far from the hydraulic motor 52. The hydraulic motor 52 is electrically connected to the power supply 3. The exhaust fan 54 is electrically connected to the power supply 3. The movement of the baffle 56 opens the outlet of the second chute on the surface of the chassis body 1. At the same time, when the exhaust fan 54 starts, it can discharge the heat inside the chassis body 1 for heat dissipation, maintaining the stability of the temperature inside the chassis body 1, and effectively preventing foreign objects from entering the inside of the chassis body 1 through the filter plate 55 during the movement of the chassis body 1.

[0024] One end of the baffle 56 close to the chassis body 1 is fixedly installed with a connecting plate 57. The connecting plate 57 slidably penetrates the inner and outer walls of the chassis body 1. A second clockwork spring is arranged between the connecting plate 57 and the chassis body 1.

[0025] During the operation of this embodiment, when the chassis body 1 is subjected to external pressure, the chassis body 1 moves downward, causing the fixed pin 42 inside the support base 41 to move upward. The upward movement of the fixed pin 42 drives the push plate 43 to move upward. The upward movement of the push plate 43 contacts and squeezes the stopper 44 to move. After the stopper 44 moves and resets, it can effectively release the pressure on the chassis body 1, converting the rigid connection into an elastic connection, avoiding deformation of the chassis body 1 under the action of pressure. At the same time, the push plate 43 continues to move upward, driving the lifting rod 45 to move upward. The upward movement of the lifting rod 45 contacts and squeezes the cross bar 47 to move in the direction close to the support rod 46. The movement of the cross bar 47 drives the connecting rod 48 to move. The movement of the connecting rod 48 drives the support rod 46 to move backward. The backward movement of the support rod 46 can provide additional support for the inner wall of the chassis body 1, further avoiding deformation of the chassis body 1 under the action of external forces, which may cause damage to the internal electronic devices and reduce the subsequent maintenance cost.

[0026] Start the power supply 3 by pressing the button 2. The power supply 3 starts and drives the exhaust fan 54 and the hydraulic motor 52 to start. The output end of the hydraulic motor 52 moves to drive the push rod 53 to move. The movement of the push rod 53 drives the baffle 56 to move. The movement of the baffle 56 opens the outlet of the second chute on the surface of the chassis body 1. At the same time, the exhaust fan 54 starts to discharge the heat inside the chassis body 1 for heat dissipation, maintaining the stability of the temperature inside the chassis body 1. At the same time, it can effectively prevent foreign objects from entering the inside of the chassis body 1 through the filter plate 55 during the movement of the chassis body 1, which may cause damage to the internal electronic devices and reduce the subsequent maintenance cost. The movement of the baffle 56 drives the connecting plate 57 to slide on the surface of the second chute, assisting the movement of the baffle 56 and improving the stability of the baffle 56 during movement.

[0027] Please refer to Figure 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a scraping device and a limiting device are further included.

[0028] A rubber plate 67 is fixedly installed at the bottom of the inner wall of the second chute. The rubber plate 67 is slidably connected to the scraping rod 64. When the scraping rod 64 moves and contacts the rubber plate 67, static electricity is generated. The static electricity can effectively make the scraping rod 64 adsorb the dust and foreign matters scraped from the surface of the filter plate 55, avoiding the flying of dust and foreign matters and affecting the scraping effect. When the work stops, the reset of the baffle 56 makes the scraping rod 64 contact the baffle 56, releasing the static electricity and discharging the adsorbed foreign matters and dust, avoiding the entry of foreign matters and dust into the interior of the chassis body 1 and reducing the subsequent maintenance cost.

The grip 73 is fixedly installed on the surface of the fixed rod 72. The pulling plate 74 is fixedly installed on the surface of the sliding blocks 71. The limiting plate 75 is slidably installed above the chassis body 1. The limiting rod 76 is fixedly installed at one end of the limiting plate 75 away from the sliding blocks 71. The movement of the limiting rod 76 contacts and squeezes the limiting plate 75 to move. The movement of the limiting plate 75 limits the baffle 56, avoiding the shaking of the baffle 56 and opening the entrance of the second chute during the movement of the chassis body 1, improving the sealing effect and preventing foreign matters from entering the interior of the chassis body 1 and damaging the internal electrical components.

[0030] Sliding blocks 71 are provided on both the left and right sides of the grip band 73. The two sliding blocks 71 are fixedly connected by an elastic telescopic rod three. A spiral spring three is provided between the limiting plate 75 and the chassis body 1. After the grip band 73 is released, the sliding block 71 is reset under the action of the elastic telescopic rod three, so that the limiting plate 75 releases the limit on the baffle 56, facilitating the use of the device.

[0031] When this embodiment works, the movement of the baffle 56 drives the movement of the receiving rod 61. The movement of the receiving rod 61 drives the movement of the sleeve 62. The movement of the sleeve 62 drives the movement of the telescopic spring rod 63. The movement of the telescopic spring rod 63 drives the movement of the sleeve rod 66. The movement of the sleeve rod 66 drives the movement of the receiving shaft 65. The movement of the receiving shaft 65 drives the scraping rod 64 to move on the surface of the filter plate 55, so that the brush on the surface of the scraping rod 64 scrapes the dust and foreign matters on the surface of the filter plate 55, avoiding the accumulation of foreign matters and dust on the surface of the filter plate 55 and affecting the heat dissipation effect. At the same time, the scraping rod 64 moves to contact the rubber plate 67 and generates static electricity. The static electricity can effectively make the scraping rod 64 adsorb the dust and foreign matters scraped from the surface of the filter plate 55, avoiding the flying of dust and foreign matters and affecting the scraping effect. When the work stops, the baffle 56 resets so that the scraping rod 64 contacts the baffle 56, releasing the static electricity and discharging the adsorbed foreign matters and dust, avoiding the entry of foreign matters and dust into the interior of the chassis body 1 and reducing the subsequent maintenance cost.

[0032] When moving the chassis body 1, by lifting the grip band 73 upward, the upward movement of the grip band 73 drives the movement of the fixed rod 72. The movement of the fixed rod 72 drives the sliding blocks 71 to move towards each other. The movement of the sliding blocks 71 drives the movement of the pull plate 74. The movement of the pull plate 74 drives the movement of the limiting rod 76. The movement of the limiting rod 76 contacts and squeezes the limiting plate 75 to move. The movement of the limiting plate 75 limits the baffle 56, avoiding the shaking of the baffle 56 during the movement of the chassis body 1 and then opening the entrance of the second chute, improving the sealing effect, and avoiding the entry of foreign matters into the interior of the chassis body 1 and causing damage to the internal electrical components. After the grip band 73 is released, the sliding block 71 is reset under the action of the elastic telescopic rod three, so that the limiting plate 75 releases the limit on the baffle 56, facilitating the use of the device.
