Description

Technical Field

[0001] The present invention relates to the technical field of computer equipment, and in particular to a desktop computer with automatic control switching of heat dissipation and dust isolation. Background Art

[0002] Desktop computers are commonly used equipment for study, office and home use, and their required period of use is generally long. During long-term use, in order to ensure their performance, hardware stability and maintenance, two major problems need to be solved, namely the common heat dissipation and dust isolation, in order to achieve stable performance for long-term use and achieve better maintenance effects.

[0003] In terms of heat dissipation, many conventional desktop computers use heat dissipation holes set on the chassis shell and cooperate with air cooling structure for heat dissipation. However, when the computer is turned off, external dust can easily enter the chassis through the heat dissipation holes, causing more dust accumulation inside the computer, affecting the normal operation and service life of the computer hardware. In terms of dust isolation, conventional desktop computers generally reduce the number of heat dissipation holes set on the outer wall of the chassis to avoid excessive dust ingress, or add filters that can isolate dust to the heat dissipation holes. Although this reduces the dust ingress inside the computer when the computer is working to a certain extent, it reduces the heat dissipation effect of air cooling, which can easily cause the internal temperature of the computer to be too high and damage the internal components of the computer. Moreover, after the computer has been working for a period of time, dust will still adhere to the heat dissipation holes or filters, further reducing the heat dissipation effect of the computer. Therefore, it is necessary to manually clean the heat dissipation holes or filters periodically. Therefore, the conventional computer chassis structure makes it impossible to take into account both heat dissipation and dust isolation effects. Summary of the invention

[0021] Optionally, the heat dissipation and dust isolation control system has an external fixing box to accommodate the linear motor, the control module, and the power supply module, and the fixing box is connected and fixed to a side panel of the hardware part fixing area of ​​the computer case by a connecting rod.

[0022] Beneficial effects:

[0023] 1. The desktop computer with automatic control switching of heat dissipation and dust isolation provided by the present invention comprises: a chassis, a heat dissipation and dust isolation frame, a power-on monitoring module and a heat dissipation and dust isolation control system.

[0024] The chassis includes a front function key area panel and a rear hardware part fixed panel, and a plurality of heat dissipation panels between the front function key area panel and the rear hardware part fixed panel, and a plurality of first through holes are arranged on the heat dissipation panels at intervals. A heat dissipation dust shielding frame is movably arranged in the chassis, and includes a plurality of heat dissipation dust shielding plates of the same number as the heat dissipation panels, and the plurality of heat dissipation dust shielding plates are respectively attached to the heat dissipation panels at corresponding positions, and a plurality of second through holes are arranged at intervals on the heat dissipation dust shielding plates, and the distribution pattern of the plurality of second through holes is the same as the distribution pattern of the plurality of first through holes, and a shielding portion is formed between the plurality of second through holes, and a heat dissipation fan is arranged inside the heat dissipation dust shielding frame.

[0025] The power-on monitoring module is electrically connected to the computer motherboard. The heat dissipation and dust isolation control system includes a control module, a power supply module and a drive module, wherein the control module is electrically connected to the power-on monitoring module in a unidirectional manner, and the drive module is transmission-connected to the heat dissipation and dust isolation frame, and is suitable for driving the heat dissipation and dust isolation frame to move between a dust isolation position and a heat dissipation position, wherein the shielding portion of the heat dissipation and dust isolation frame shields the first through hole in the dust isolation position, and the second through hole is directly opposite to the first through hole in the heat dissipation position.

[0026] Among them, when the computer is turned on, the power-on monitoring module is powered on and transmits the computer power-on signal to the control module in a unidirectional manner, and the control module controls the driving module to drive the heat dissipation dust isolation frame to move from the dust isolation position to the heat dissipation position, and controls the cooling fan to work. When the computer is shut down, the power-on monitoring module is powered off and stops sending the computer power-on signal to the control module, and the control module controls the driving module to drive the heat dissipation dust isolation frame to move from the heat dissipation position to the dust isolation position, and controls the cooling fan to stop working.

[0027] With such an arrangement, after the computer is turned on, the heat dissipation dust shielding frame moves to the heat dissipation position, and the first through hole and the second through hole are directly opposite to each other, so that the air environment inside the computer case is connected to the external air environment, and the cooling fan can drive the air inside the case to exchange with the external air, thereby achieving a heat dissipation effect. After the computer is turned off, the heat dissipation dust shielding frame moves to the dust shielding position, blocking part of the first through hole. In this state, external dust cannot enter the interior of the case through the first through hole, thereby achieving a dust shielding effect. Compared with conventional computer cases, there is no need to reduce the number of heat dissipation holes or add filters to isolate dust. It can also ensure efficient heat dissipation when the computer is working and good dust isolation when the computer is turned off, thereby overcoming the conflict between heat dissipation and dust isolation of the computer case.

[0028] Therefore, the second through holes of the multiple heat dissipation and dust isolation plates of the heat dissipation and dust isolation frame are opposite to the first through holes and the heat dissipation fan works to achieve heat dissipation, and the shielding part is opposite to the first through hole to achieve dust isolation; the control module of the heat dissipation and dust isolation control system sends a computer power-on signal to the power-on monitoring module after monitoring the computer startup via the power-on monitoring module unidirectionally connected to it, and then controls the linear motor of the drive module to work forward and make the heat dissipation and dust isolation frame move once to achieve heat dissipation; after no signal is received, the linear motor of the drive module is controlled to work in the reverse direction to make the heat dissipation and dust isolation frame move back once to achieve computer dust isolation switching; through power-on heat dissipation and power-off dust isolation control, the convenience and intelligence of heat dissipation and dust isolation switching are improved.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a desktop computer with automatic control switching of heat dissipation and dust isolation, including: a chassis 1, a heat dissipation and dust isolation frame 2, a power-on monitoring module 4 and a heat dissipation and dust isolation control system 3.

[0039] The chassis 1 includes a front function key area panel 11 and a rear hardware part fixed panel 12, and a plurality of heat dissipation panels 13 between the front function key area panel 11 and the rear hardware part fixed panel 12, and a plurality of first through holes 131 are arranged at intervals on the heat dissipation panels 13. The heat dissipation dust shielding frame 2 is movably arranged in the chassis 1, and includes a plurality of heat dissipation dust shielding plates 21 of the same number as the heat dissipation panels 13, and the plurality of heat dissipation dust shielding plates 21 are respectively attached to the heat dissipation panels 13 at corresponding positions, and a plurality of second through holes 211 are arranged at intervals on the heat dissipation dust shielding plates 21, and the distribution pattern of the plurality of second through holes 211 is the same as the distribution pattern of the plurality of first through holes 131, and a shielding portion 212 is formed between the plurality of second through holes 211, and a heat dissipation fan 23 is arranged inside the heat dissipation dust shielding frame.

[0040] The power-on monitoring module 4 is electrically connected to the computer motherboard 121. The heat dissipation and dust isolation control system 3 includes a control module 31, a power supply module 32 and a drive module 33. The control module 31 is electrically connected to the power-on monitoring module 4 in a unidirectional manner. The drive module 33 is transmission-connected to the heat dissipation and dust isolation frame 2, and is suitable for driving the heat dissipation and dust isolation frame 2 to move between the dust isolation position and the heat dissipation position. In the dust isolation position, the shielding portion 212 of the heat dissipation and dust isolation frame shields the first through hole 131. In the heat dissipation position, the second through hole 211 and the first through hole 131 are directly opposite.

[0041] Among them, when the computer is turned on, the power-on monitoring module 4 is powered on and transmits the computer power-on signal to the control module 31 in a unidirectional manner. The control module 31 controls the driving module 33 to drive the heat dissipation dust isolation frame 2 to move from the dust isolation position to the heat dissipation position, and controls the heat dissipation fan 23 to work. When the computer is shut down, the power-on monitoring module 4 is powered off and stops sending the computer power-on signal to the control module 31. The control module 31 controls the driving module 33 to drive the heat dissipation dust isolation frame 2 to move from the heat dissipation position to the dust isolation position, and controls the heat dissipation fan 23 to stop working.

[0042] With such a configuration, after the computer is turned on, the heat dissipation dust shielding frame 2 moves to the heat dissipation position, and the first through hole 131 and the second through hole 211 are directly opposite to each other so that the air environment inside the computer case 1 is connected to the external air environment, and the heat dissipation fan 23 can drive the air inside the case 1 to exchange with the external air, thereby achieving a heat dissipation effect. After the computer is turned off, the heat dissipation dust shielding frame 2 moves to the dust shielding position, and the shielding part 212 blocks the first through hole 131. In this state, external dust cannot enter the case 1 through the first through hole 131, thereby achieving a dust shielding effect. Compared with conventional computer cases, there is no need to reduce the number of heat dissipation holes or add a filter to isolate dust. It can also ensure efficient heat dissipation when the computer is working and good dust isolation when the computer is turned off, thereby overcoming the conflict between heat dissipation and dust isolation of the computer case. In addition, the power-on monitoring module 4 and the heat dissipation and dust isolation control system 3 can realize automatic switching between heat dissipation and dust isolation without manual switching, thereby improving convenience.

[0043] like Figure 1 As shown, in this embodiment, the control module 31 includes a controller, which can be a PLC controller. When the controller receives the computer power-on signal sent from the power-on monitoring module 4, it sends a heat dissipation signal to the drive module 33, and when it stops receiving the computer power-on signal sent from the power-on monitoring module 4, it sends a dust isolation signal to the drive module 33. The drive module 33 includes a linear motor 34, the output end of the linear motor 34 is transmission-connected to the heat dissipation and dust isolation frame 2, and the linear motor 34 drives the heat dissipation and dust isolation frame 2 to move to the heat dissipation position or the dust isolation position based on the heat dissipation signal or the dust isolation signal. For example, when the PLC controller receives a computer power-on signal sent from the power-on monitoring module 4, the heat dissipation signal is sent to the driving module 33, and the output end of the linear motor 34 drives the heat dissipation dust shielding frame 2 to move from the dust shielding position to the heat dissipation position, so that the state in which the blocking portion 212 blocks the first through hole 131 is changed to the state in which the second through hole 211 and the first through hole 131 are connected, thereby allowing the air inside the chassis 1 to flow with the outside air. Afterwards, when the PLC controller does not receive the computer power-on signal sent from the power-on monitoring module 4, the dust shielding signal is sent to the driving module 33, and the output end of the linear motor 34 drives the heat dissipation dust shielding frame 2 to move from the heat dissipation position to the dust shielding position, thereby achieving dust isolation.

[0044] It should be noted that when the PLC controller receives the computer power-on signal and stops receiving the computer power-on signal, it is an instantaneous trigger condition. When the PLC continues to receive the computer power-on signal during this period, the PLC controller will not send a control instruction to the drive module 33.

[0045] like Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the linear motor 34 is a bidirectional drive motor and is arranged on the hardware part fixing panel 12, and a drive rod 35 is arranged on the heat dissipation and dust isolation frame 2, and a threaded hole 351 that matches with the output end of the linear motor 34 is arranged on the drive rod 35. The linear motor 34 is suitable for driving the heat dissipation and dust isolation frame 2 to move to the dust isolation position along the first direction through its output end and the threaded hole 351 of the drive rod 35, or, to move to the heat dissipation position in a second direction opposite to the first direction. For example, a linear motor mover 341 is arranged in the linear motor 34, and the linear motor mover 341 can move in the clockwise direction and the counterclockwise direction respectively. It rotates bidirectionally in the clockwise direction, and the part where the linear motor mover 341 and the threaded hole 351 cooperate is a threaded rod, thereby realizing that the heat dissipation and dust shielding frame 2 is driven by the driving rod 35 to move in the first direction or the second direction. The first direction can be the direction in which the heat dissipation and dust shielding frame 2 moves from the panel 11 close to the function key area to the panel 12 close to the hardware part, that is, the direction of movement from the dust shielding position to the heat dissipation position. On the contrary, the second direction can be the direction in which the heat dissipation and dust shielding frame 2 moves from the panel 12 close to the hardware part to the panel 11 close to the function key area, that is, the direction of movement from the heat dissipation position to the dust shielding position.

[0046] like Figure 2 and Figure 3 As shown, in the present embodiment, a guide groove 22 extending along a first direction is provided on the heat dissipation dust shield frame 2, and a slide rail 15 extending along the first direction is provided on the inner wall of the chassis 1, and the guide groove 22 is guided and cooperated with the slide rail 15, and the guide groove 22 is a depression formed at the outer edge of the heat dissipation dust shield frame 2, and the slide rail 15 is a convex ridge with the same cross-sectional size as the guide groove 2 and formed at the inner edge of the chassis 1. Therefore, while realizing the guiding function, it will not affect the sliding relationship between the heat dissipation dust shield frame 2 and the inner wall of the chassis, thereby ensuring its dust isolation effect.

[0047] like Figure 3 As shown, in the present embodiment, stop portions 151 are provided at both ends of the slide rail 15, and the stop portions 151 are detachably connected to the slide rail 15. After the installation of the heat dissipation and dust shielding frame 2 is completed, the two stop portions 151 can be respectively installed at both ends of the slide rail 15. The size of the stop portion 151 is larger than the size of the guide groove 22, and the stop portion 151 is a block structure larger than the cross-sectional size of the slide rail 15, thereby limiting the heat dissipation and dust shielding frame 2.

[0048] like Figure 1As shown, in the present embodiment, the power-on monitoring module 4 includes a current sensor or a voltage sensor for monitoring the power-on of the computer motherboard 121, which is powered on when the computer is turned on and sends a computer power-on signal to the control module 31 of the heat dissipation and dust isolation control system 3, and is powered off and stops working when the computer is turned off, so that the control module 31 no longer receives the computer power-on signal, and enables the control module 31 to implement heat dissipation control and dust isolation control. The current sensor or the voltage sensor can detect components that have current or voltage only after the computer motherboard is turned on, so as to distinguish the computer power-on state and the shutdown state. The power-on monitoring module 4 and the control module 31 are unidirectionally electrically connected through the diode 5 and transmit electrical signals unidirectionally, so that the power-on monitoring module 4 only performs power-on monitoring when the computer is turned on, and is not disturbed by the power-on of the heat dissipation and dust isolation control system 3 that is powered on for a long time, and further powers off and stops sending electrical signals to the control module 31 when the computer is powered off.

[0049] like Figure 2 and Figure 3 As shown, in the present embodiment, a plurality of cooling fans 23 are respectively arranged on a plurality of cooling dust shielding plates 21, and the air supply range of the cooling fans 23 covers a plurality of second through holes 211. The air supply directions of the cooling fans 23 on the relative cooling dust shielding plates 21 are the same. For example, the air supply directions of the plurality of cooling fans 23 can refer to three-dimensional cooling, and of course can also be determined according to actual conditions.

[0050] like Figure 1 As shown, in the present embodiment, the control module 31 includes a timer 311. After the single working time of the driving module 33 reaches the preset time of the timer 311, the heat dissipation dust shielding frame 2 moves from the dust shielding position to the heat dissipation position, or the heat dissipation dust shielding frame 2 moves from the heat dissipation position to the dust shielding position. Since the movement stroke of the threaded hole 351 driven by the linear motor mover 341 is fixed within a certain time, the preset time can be set by the timer 311, and the single heat dissipation dust shielding frame 2 can be moved from the dust shielding position to the heat dissipation position within the predetermined time, or the single heat dissipation dust shielding frame 2 can be moved from the heat dissipation position to the dust shielding position.

[0051] like Figure 2As shown, in this embodiment, the plurality of first through holes 131 and the plurality of second through holes 211 are distributed in the same matrix, the length dimension of the heat dissipation panel 13 in the first direction is greater than the length dimension of the heat dissipation dust shielding frame 2 in the first direction, and a straight panel portion 132 without the first through hole 131 is formed at one end of the heat dissipation panel 13 near the function key area panel, thereby leaving space for the heat dissipation dust shielding frame 2 to move between the dust shielding position and the heat dissipation position, and at the same time, the straight panel portion 132 can also play a dust shielding role, and the size of the shielding portion 212 in the first direction is greater than the size of the first through hole 131, so that the shielding portion 212 can completely shield the first through hole 131. For example, the plurality of heat dissipation dust shielding plates 21 of the heat dissipation dust shielding frame 2 can be detachably connected or integrally arranged and directly attached to the plurality of heat dissipation panels 13, the heat dissipation panels 13 include left and right panels and upper and lower panels of the chassis 1, and a support boss 16 is arranged at the bottom of the desktop computer chassis 1, so that the lower panel of the chassis 1 is suspended to implement heat dissipation.

[0052] like Figure 4 As shown, in this embodiment, the function key area panel 11 and / or the hardware part fixed panel 12 are provided with an opening and closing door 111, and the hardware part fixed panel 12 and / or the function key area panel 11 are detachable chassis panels.

[0053] like Figure 5 As shown, in this embodiment, the heat dissipation and dust isolation control system 3 peripheral system fixing box 36 is used to accommodate the linear motor 34, the control module 31, and the power supply module, and is connected and fixed to a side panel of the hardware part fixing area of ​​the computer case 1 through the fixing box 36 with a connecting rod 37.

[0054] The installation steps of the desktop computer with automatic control switching of heat dissipation and dust isolation provided in this embodiment are as follows:

[0055] The hardware fixing area of ​​the chassis 1 is a detachable chassis panel, and the function key area panel 11 is provided with an opening and closing door. When installing the heat dissipation and dust shielding frame 2 in the chassis 1, first disassemble the detachable left panel and / or right panel and the detachable hardware fixing panel, install the drive rod 35 into the left and right heat dissipation and dust shielding panels of the heat dissipation and dust shielding frame 2, and then screw the linear motor mover 341 in the peripheral system fixing box 36 into the threaded hole 351 of the drive rod to complete the fixation of the peripheral system fixing box 36 and the drive rod 35; then support the guide groove 22 of the heat dissipation and dust shielding frame 2 on the movable slide rail 15 in the computer chassis 1 and install the stopper 151 at both ends of the movable slide rail 15 to complete the heat dissipation and dust shielding frame 2. The thermal dust shield frame 2, the peripheral system fixing box 36, and the movable slide rail 15 of the chassis 1 are connected; then the connecting rod 37 of the stud bolt is screwed into the threaded holes of the fixing box 36 and the panel where the hardware part fixing area is located and fixed with a nut to complete the fixation of the fixing box 36 and the panel where the hardware part fixing area is located; then the detachable left panel and / or right panel are closed and installed, and the detachable hardware part fixing panel is closed to complete the installation, and the front function key area panel 11 is provided with an opening and closing door to facilitate the connection and installation of the function keys and wires of the front panel with the hardware fixing area. At the same time, the left panel and / or right panel can be installed after this step is completed, so as to facilitate the more convenient connection and installation of wires and other components.

[0056] The working principle of the desktop computer with automatic control switching of heat dissipation and dust isolation provided in this embodiment is as follows:
