Description

Technical Field

[0001] The invention belongs to the technical field of computer accessories, and in particular relates to a heat dissipation bracket for a computer and a heat dissipation method thereof. Background Art

[0002] The computer case bracket is a bracket used to support, fix and protect the computer case and its internal hardware devices. The case bracket provides stable support for the computer case to ensure the stability of the case and its internal hardware devices. Through the bracket, the case can be firmly fixed in a specific position to avoid shaking or tilting during use. The computer bracket can raise the case to provide more air intake space at the bottom to assist in heat dissipation.

[0003] A conventional bracket is mainly composed of a base plate and a support foot or universal wheel at the bottom. In order to assist the air intake at the bottom of the chassis, heat dissipation holes are often opened on the bracket, and a fan is set on the heat dissipation holes to assist the air intake. However, long-term use can easily lead to dust accumulation at the air inlet, affecting the overall heat dissipation effect. At the same time, when the chassis is not placed on the bracket, dust will also enter, affecting the overall heat dissipation effect.

[0004] At the same time, after the chassis is placed on the bracket, in order to prevent the chassis from tilting or tipping over, a fixing component is used to fix the chassis. The current method is mainly to fix it with a screw rod and a splint. This fixing method requires controlling the appropriate force. When facing some chassis made of glass, there is a risk of crushing the glass. Summary of the invention

[0005] The object of the present invention is to provide a heat dissipation bracket for a computer and a heat dissipation method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: A heat dissipation support bracket for a computer, including a bottom plate, wherein a ventilation groove is provided at the top end of the bottom plate, universal wheels are fixedly installed at the four corner positions of the bottom end of the bottom plate, a heat dissipation box is fixedly installed at the bottom end of the bottom plate, extension guide rails are fixedly installed at the left and right ends of the bottom plate, a heat dissipation box is fixedly installed at the bottom end of the bottom plate, heat dissipation fans are installed at equal intervals inside the heat dissipation box by bolts, support foot limit grooves are provided at the positions near the four corners of the top end of the bottom plate, fixing components are movably clamped at the top ends of the extension guide rails, inner cleaning brushes are movably clamped at the front and rear ends of the inner side surface of the heat dissipation box, outer cleaning brushes are movably clamped at the front and rear ends of the inner side surface of the heat dissipation box, one end of the inner cleaning brush penetrates through the heat dissipation box and is fixedly connected to a locking plate, the front and rear ends of the inner side surface of the locking plate are connected between the outer cleaning brush and the inner cleaning brush, the locking plates are distributed on the left and right sides of the heat dissipation box, and the bottom ends of the two locking plates are connected to the left and right sides of the top end of the linkage component, auxiliary support components are installed at the relatively far ends of the two extension guide rails, and one end of the auxiliary support component is connected to the locking plate.

[0007] Before the use of the device, the device is in an initial state, that is, the bottom end of the linkage component is in contact with the ground. At this time, the device can be moved to a suitable position and the ground is kept level, and the distance between the two fixing components is the minimum value at this time.

[0008] As a further technical solution of the present invention, the inner side surface of the outer cleaning brush is in contact with the outer side surface of the heat dissipation box, the inner side surface of the inner cleaning brush is in contact with the inner side surface of the heat dissipation box, and the outer cleaning brush and the inner cleaning brush are displaced left and right relative to the heat dissipation box.

[0009] In the initial state, that is, when the top end of the bottom plate is not in contact with the bottom end of the chassis, the linkage component is in the initial state at this time, and the distance between the two locking plates is the minimum value, that is, the two locking plates are relatively close to each other. At this time, the outer cleaning brush and the inner cleaning brush respectively block the outer side surface and the inner side surface of the heat dissipation box. At this time, the heat dissipation slots of the heat dissipation box can be completely blocked, and external dust cannot enter the inside of the heat dissipation box, realizing dust prevention.

[0010] By utilizing the cooperation between the linkage component and the locking plate, and the cooperation between the outer cleaning brush and the inner cleaning brush and the heat dissipation box, the device can completely block the heat dissipation box in the initial state, prevent external dust from entering the inside of the heat dissipation box, realize automatic dust prevention when the device is not in use, and automatically expose the heat dissipation slots of the heat dissipation box when the device is in use. The whole process is automatically completed, and the entry of dust when the device is not in use can be effectively reduced.

[0011] As a further technical solution of the present invention, the linkage assembly includes a movable plate. At positions near the four corners of the top end of the movable plate, first fixing seats are fixedly installed. One end of each first fixing seat away from the movable plate is movably connected to a connecting rod through a rotating shaft.

[0012] As a further technical solution of the present invention, one end of the connecting rod away from the first fixing seat is movably connected to a second fixing seat through a rotating shaft, and the bottom end of the second fixing seat is connected to the bottom end of the locking plate.

[0013] As a further technical solution of the present invention, the linkage assembly includes a fixed pipe. The top end of the fixed pipe is connected to the bottom end of the heat dissipation box. A limiting plate is movably sleeved inside the fixed pipe. The bottom end of the limiting plate penetrates through the bottom end of the fixed pipe and is connected to the middle part of the movable plate.

[0014] A return spring is movably sleeved on the outer side of the movable rod. The upper and lower ends of the return spring are respectively connected to the bottom end of the limiting plate and the bottom end of the inner cavity of the fixed pipe. When the return spring is in the initial state, the movable plate is at the lowest point, and the outer cleaning brush and the inner cleaning brush respectively completely block the inner side and the outer side of the heat dissipation box.

[0015] When the bottom end of the chassis is completely placed above the bottom plate, the gravity of the chassis at this time can push the bottom plate to displace downward. When the bottom plate displaces downward, it can synchronously drive the fixed pipe to displace downward. At this time, the distance between the movable plate and the bottom plate decreases, that is, the movable plate and the movable rod displace upward relative to the bottom plate. At this time, multiple connecting rods deflect in a direction away from the middle of the bottom plate, and exert a thrust on the locking plate at the top. At this time, the two locking plates move away from each other accordingly, and drive the outer cleaning brush and the inner cleaning brush to displace toward both sides of the heat dissipation box until the heat dissipation slots opened on the heat dissipation box are exposed, and then air intake can be realized through the heat dissipation slots;

[0016] When there is a lot of dust covering the surface of the heat dissipation box and affecting its heat dissipation, the bottom plate can be picked up. At this time, the return spring can automatically reset and drive the bottom plate to displace upward. At this time, the distance between the movable plate and the bottom plate increases, and multiple connecting rods displace toward the middle of the bottom plate, and drive the two locking plates to move closer to each other. Finally, it drives the outer cleaning brush and the inner cleaning brush to approach the middle of the heat dissipation box, and uses the friction effect to realize the automatic cleaning of the inner and outer surfaces of the heat dissipation box, completing the self-cleaning process.

[0017] By utilizing the gravity of the chassis itself during installation and applying it to the linkage assembly, through the cooperation between the linkage assembly and the locking plate, after the chassis is installed in place, the heat dissipation slots of the heat dissipation box can be automatically opened. When the chassis is removed, the heat dissipation box can be automatically cleaned, avoiding the problem of dust blockage that is likely to occur in traditional devices after long-term use, reducing the maintenance difficulty, and improving the practicability.

[0018] As a further technical solution of the present invention, the fixing component includes a guiding block, which is movably clamped with the extension guide rail. One end of the guiding block is fixedly connected with a limiting spring located inside the extension guide rail, and the other end of the limiting spring is connected to one side of the inner cavity of the extension guide rail.

[0019] As a further technical solution of the present invention, a mounting plate is fixedly installed at the top end of the guiding block. Telescopic rods are fixedly installed on both the left and right sides of the top end of the mounting plate. The fixing component further includes a limiting block, and the top ends of the two telescopic rods are connected to the front and rear sides of the bottom end of the limiting block.

[0020] As a further technical solution of the present invention, a guiding inclined surface is provided at the top end of the limiting block. When the limiting spring is in the initial state, the distance between the two mounting plates is at the minimum value.

[0021] When the chassis is placed above the bottom plate, the bottom end of the chassis can be in contact with the two guiding inclined surfaces at this time. At the same time, through the guiding action of the guiding inclined surface and the pressing action of the chassis, the two limiting blocks are driven to move away from each other. At this time, the limiting spring can be compressed. Until the bottom end of the chassis is in contact with the top end of the bottom plate, at this time, the limiting spring can automatically reset and drive the two mounting plates to move relatively closer. At this time, the telescopic rod can be shortened by pressing down the limiting block until the inner side surfaces of the limiting block are in contact with both sides of the top end of the chassis, and the limiting and fixing process of the chassis can be completed.

[0022] By utilizing the self-gravity of the chassis and the cooperation between the fixing component and the extension guide rail, the limiting and fixing process of the chassis can be automatically realized only after the chassis is installed in place. The entire process does not require manual rotation of devices such as lead screws. And when disassembling, the chassis can be taken out only by lifting it upward, which can realize the quick disassembly and assembly of the chassis, reduce the maintenance difficulty, and avoid damage to the chassis caused by uneven force.

[0023] As a further technical solution of the present invention, the auxiliary support component includes an L-shaped frame. One side of the L-shaped frame is connected to the extension guide rail. A longitudinal guide rail is fixedly connected to the bottom end of the L-shaped frame. A longitudinal clamping block is movably clamped inside the longitudinal guide rail. The auxiliary support component further includes a mounting member on one side, and the mounting member is connected to the locking plate. Support rods are fixedly installed at the bottom ends of the longitudinal clamping blocks. The bottom ends of the support rods penetrate through the bottom end of the longitudinal guide rail and are fixedly connected with suction cups. A third fixing seat is fixedly connected to the side of the mounting member close to the longitudinal guide rail. A fourth fixing seat is fixedly installed on the side of the longitudinal clamping block close to the mounting member. A linkage rod is movably connected between the third fixing seat and the fourth fixing seat.

[0024] In the normal state, it can be displaced through the universal wheel control device. When the chassis is placed above the bottom plate, since the distance between the bottom plate and the movable plate is reduced, and due to the relative separation of the two locking plates, at this time, the two mounting parts can be driven to move relatively away from each other, and the linkage rod can be driven to deflect obliquely downward. At this time, a downward pressure can be applied to the longitudinal block, and the support rod and the suction cup can be driven to move downward until the suction cup contacts the ground, replacing the support of the universal wheel and completing the auxiliary fixing process.

[0025] By utilizing the cooperation between the linkage component and the locking plate, and the cooperation between the locking plate and the auxiliary support component, after the chassis is placed in place, the automatic descent of the suction cup can be realized, replacing the support of the universal wheel and completing the automatic auxiliary support process. After the chassis is installed in place, the entire device can be automatically fixed to the ground to prevent displacement, further improving the stability of the chassis.

[0026] A heat dissipation method for a heat dissipation support bracket of a computer, comprising the following steps:

[0027] S1: In the initial state, the device can be placed on a suitable horizontal ground, and the corresponding computer chassis can be placed down from the top of the device. At this time, the bottom end of the chassis can contact the inner sides of the two guiding inclined surfaces, and under the guiding action of the guiding inclined surfaces, the limiting spring can be driven to be compressed. At this time, the two mounting plates move relatively away from each other until the bottom end of the chassis contacts the bottom plate.

[0028] S2: At the same time, the limiting spring automatically resets to drive the two mounting plates to move relatively closer until the two limiting blocks are driven to move relatively closer. By adjusting the height of the telescopic rod, the height of the limiting blocks is adjusted until the inner sides of the limiting blocks contact both sides of the top end of the chassis, completing the fixing process of the chassis.

[0029] S3: When the chassis is placed on the bottom plate, the bottom plate moves downward at this time, that is, drives the fixed pipe to move downward. At this time, the reset spring is compressed, and the distance between the movable plate and the heat dissipation box decreases. The connecting rod deflects towards a position away from the middle and applies a pulling force to the two locking plates. At this time, the two locking plates move relatively away from each other, and drive the outer cleaning brush and the inner cleaning brush to move towards both sides, exposing the heat dissipation slots on the side of the heat dissipation box.

[0030] S4: By turning on the heat dissipation fan, external air can be sucked into the interior of the heat dissipation box and enter the interior of the chassis through the ventilation slots to achieve the intake operation. When the heat dissipation box is blocked, by removing the chassis, the linkage component automatically resets at this time, driving the outer cleaning brush and the inner cleaning brush to move towards the middle of the heat dissipation box to clean the inner and outer sides of the heat dissipation box, completing the self-cleaning process.

[0031] The beneficial effects of the present invention are as follows:

[0032] (1) When the chassis is installed, the present invention utilizes its own gravity and applies it to the linkage component. Through the cooperation between the linkage component and the locking plate, after the chassis is installed in place, the heat dissipation slots of the heat dissipation box can be automatically opened. When the chassis is removed, the heat dissipation box can be automatically cleaned, avoiding the problem of dust blockage that is likely to occur in traditional devices after long-term use, reducing the maintenance difficulty, and improving the practicability.

[0033] (2) By utilizing the self-gravity of the chassis and the cooperative effect between the fixing component and the extension guide rail, the present invention can automatically realize the limiting and fixing process of the chassis only after the chassis is installed in place. The whole process does not require manual rotation of devices such as lead screws. When disassembling, the chassis can be taken out only by lifting it upward, realizing the rapid disassembly and assembly of the chassis, reducing the maintenance difficulty, and avoiding damage to the chassis caused by uneven stress.

[0034] (3) By utilizing the cooperation between the linkage component and the locking plate, and the cooperative effect between the external cleaning brush and the internal cleaning brush and the heat dissipation box, the device can completely block the heat dissipation box in the initial state, preventing external dust from entering the interior of the heat dissipation box, realizing automatic dust prevention when the device is not in use, and automatically exposing the heat dissipation slots of the heat dissipation box when the device is in use. The whole process is automatically completed, effectively reducing the entry of dust when the device is not in use.

[0035] (4) By utilizing the cooperation between the linkage component and the locking plate, and the cooperative effect between the locking plate and the auxiliary support component, after the chassis is placed in place, the automatic descent of the suction cup can be realized, replacing the support of the universal wheels to complete the automatic auxiliary support process. After the chassis is installed in place, the whole device can be automatically fixed to the ground to prevent displacement, further improving the stability of the chassis.

Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] Such as Figures 1 to 8As shown in the figure, in an embodiment of the present invention, a heat dissipation support bracket for a computer includes a bottom plate 1. An air permeable groove 2 is formed at the top end of the bottom plate 1. Universal wheels 3 are fixedly installed at the four corner positions at the bottom end of the bottom plate 1. A heat dissipation box 4 is fixedly installed at the bottom end of the bottom plate 1. Extension guide rails 6 are fixedly installed at both the left and right ends of the bottom plate 1. A heat dissipation box 4 is fixedly installed at the bottom end of the bottom plate 1. Heat dissipation fans 5 are installed in the heat dissipation box 4 at equal intervals by bolts. Foot limiting grooves 8 are formed at the positions near the four corners at the top end of the bottom plate 1. Fixed components 7 are movably clamped at the top ends of the extension guide rails 6. Inner cleaning brushes 10 are movably clamped at the front and rear ends of the inner side surface of the heat dissipation box 4. Outer cleaning brushes 9 are movably clamped at the front and rear ends of the inner side surface of the heat dissipation box 4. One end of the inner cleaning brush 10 passes through the heat dissipation box 4 and is fixedly connected to a locking plate 11. The front and rear ends of the inner side surface of the locking plate 11 are connected between the outer cleaning brush 9 and the inner cleaning brush 10. The locking plates 11 are distributed on both the left and right sides of the heat dissipation box 4, and the bottom ends of the two locking plates 11 are connected to the left and right sides of the top end of the linkage component 12. Auxiliary support components 13 are installed at the relatively far ends of the two extension guide rails 6. One end of the auxiliary support component 13 is connected to the locking plate 11.

[0051] Before the device is used, the device is in an initial state, that is, the bottom end of the linkage component 12 is in contact with the ground. At this time, the device can be moved to a suitable position and the ground is kept level, and the distance between the two fixed components 7 is the minimum value at this time.

[0052] As Figure 1 and Figure 2 and Figure 6 and Figure 7 As shown in the figure, the inner side surface of the outer cleaning brush 9 is in contact with the outer side surface of the heat dissipation box 4, the inner side surface of the inner cleaning brush 10 is in contact with the inner side surface of the heat dissipation box 4, and the outer cleaning brush 9 and the inner cleaning brush 10 move left and right relative to the heat dissipation box 4.

[0053] In the initial state, that is, when the top end of the bottom plate 1 is not in contact with the bottom end of the chassis, at this time the linkage component 12 is in the initial state, and the distance between the two locking plates 11 is the minimum value, that is, the two locking plates 11 are relatively close to each other. At this time, the outer cleaning brush 9 and the inner cleaning brush 10 respectively block the outer side surface and the inner side surface of the heat dissipation box 4. At this time, the heat dissipation slots of the heat dissipation box 4 can be completely blocked, and external dust cannot enter the interior of the heat dissipation box 4, realizing dust prevention.

[0054] By utilizing the cooperation between the linkage component 12 and the locking plate 11, as well as the cooperation between the outer cleaning brush 9 and the inner cleaning brush 10 and the heat dissipation box 4, the device can completely block the heat dissipation box 4 in the initial state, preventing external dust from entering the interior of the heat dissipation box 4, achieving automatic dust prevention when the device is not in use, and automatically exposing the heat dissipation slots of the heat dissipation box 4 when the device is in use. The entire process is completed automatically, effectively reducing the entry of dust when the device is not in use.

[0055] As Figure 2 and Figure 4 as well as Figure 7 and Figure 8 shown, the linkage component 12 includes a movable plate 121. At positions near the four corners of the top end of the movable plate 121, first fixed seats 122 are fixedly installed. One end of each first fixed seat 122 away from the movable plate 121 is movably connected to a connecting rod 124 through a rotating shaft. One end of the connecting rod 124 away from the first fixed seat 122 is movably connected to a second fixed seat 123 through a rotating shaft. The bottom end of the second fixed seat 123 is connected to the bottom end of the locking plate 11. The linkage component 12 includes a fixed tube 125. The top end of the fixed tube 125 is connected to the bottom end of the heat dissipation box 4. A limiting plate 127 is movably sleeved inside the fixed tube 125. The bottom end of the limiting plate 127 penetrates the bottom end of the fixed tube 125 and is connected to the middle part of the movable plate 121. A return spring 128 is movably sleeved on the outer side of the movable rod 126. The upper and lower ends of the return spring 128 are respectively connected to the bottom end of the limiting plate 127 and the bottom end of the inner cavity of the fixed tube 125. When the return spring 128 is in the initial state, the movable plate 121 is at the lowest point, and the outer cleaning brush 9 and the inner cleaning brush 10 completely block the inner side and the outer side of the heat dissipation box 4 respectively.

[0056] Embodiment 1: When the bottom end of the chassis is completely placed above the bottom plate 1, the gravity of the chassis at this time can push the bottom plate 1 to displace downward. When the bottom plate 1 displaces downward, it can synchronously drive the fixed tube 125 to displace downward. At this time, the distance between the movable plate 121 and the bottom plate 1 decreases, that is, the movable plate 121 and the movable rod 126 displace upward relative to the bottom plate 1. At this time, the multiple connecting rods 124 deflect in a direction away from the middle of the bottom plate 1, and apply a thrust to the locking plate 11 at the top. At this time, the two locking plates 11 move away from each other accordingly, and drive the outer cleaning brush 9 and the inner cleaning brush 10 to displace toward both sides of the heat dissipation box 4 until the heat dissipation slots opened on the heat dissipation box 4 are exposed, and then air intake can be achieved through the heat dissipation slots;

[0057] When there is a lot of dust covering the surface of the heat dissipation box 4, affecting its heat dissipation, the bottom plate 1 can be lifted. At this time, the reset spring 128 can automatically reset and drive the bottom plate 1 to move upward. At this time, the distance between the movable plate 121 and the bottom plate 1 increases accordingly, and multiple connecting rods 124 move towards the middle of the bottom plate 1, driving the two locking plates 11 to move relatively closer. Finally, it drives the outer cleaning brush 9 and the inner cleaning brush 10 to approach the middle of the heat dissipation box 4, and uses the friction effect to automatically clean the inner and outer surfaces of the heat dissipation box 4, completing the self-cleaning process.

[0058] When the chassis is installed, by utilizing its own gravity and acting on the linkage assembly 12, through the cooperation between the linkage assembly 12 and the locking plate 11, after the chassis is installed in place, the heat dissipation slots of the heat dissipation box 4 can be automatically opened. When the chassis is removed, the heat dissipation box 4 can be automatically cleaned, avoiding the problem of dust blockage that is prone to occur in traditional devices after long-term use, reducing the maintenance difficulty, and improving the practicability.

[0059] As Figure 1 and Figure 2 and Figure 3 As shown, the fixing component 7 includes a guide block 701, which is movably clamped with the extension guide rail 6. One end of the guide block 701 is fixedly connected with a limit spring 702 located inside the extension guide rail 6, and the other end of the limit spring 702 is connected to one side of the inner cavity of the extension guide rail 6. The top of the guide block 701 is fixedly installed with a mounting plate 703. On the left and right sides of the top of the mounting plate 703, telescopic rods 704 are fixedly installed. The fixing component 7 further includes a limit block 705. The tops of the two telescopic rods 704 are connected to the front and rear sides of the bottom end of the limit block 705. A guide inclined surface 706 is opened at the top of the limit block 705. When the limit spring 702 is in the initial state, the distance between the two mounting plates 703 is the minimum value.

[0060] Embodiment 2: When the chassis is placed above the bottom plate 1, the bottom end of the chassis can be in contact with the two guide inclined surfaces 706 at this time. At the same time, through the guiding action of the guide inclined surfaces 706 and the pressing action of the chassis, the two limit blocks 705 are driven to move away from each other. At this time, the limit spring 702 can be compressed. When the bottom end of the chassis is in contact with the top end of the bottom plate 1, the limit spring 702 can automatically reset and drive the two mounting plates 703 to move relatively closer. At this time, by pressing down the limit block 705, the telescopic rod 704 can be shortened until the inner side surfaces of the limit blocks 705 are in contact with the two sides of the top end of the chassis, and the limiting and fixing process of the chassis can be completed.

[0061] By utilizing the self - gravity of the chassis and the cooperation between the fixing component 7 and the extension guide rail 6, the limit fixing process of the chassis can be automatically realized only after the chassis is installed in place. The whole process does not require manual rotation of devices such as lead screws. And when disassembling, the chassis can be taken out only by lifting it upward, which can realize the quick disassembly and assembly of the chassis, reduce the maintenance difficulty, and avoid damage to the chassis caused by uneven stress.

[0062] Embodiment 3: As Figure 9 and Figure 10 and Figure 11 shown, the structure of this embodiment is basically the same as that of the above - mentioned embodiment. The difference is that the shape of the movable plate 121 is rectangular, and the four universal wheels 3 are not installed on the bottom plate 1, but are installed at the four corners of the bottom end of the movable plate 121. At the same time, both the front and rear sides of the fixing tube 125 near the top are fixedly sleeved with air delivery pipes 129, and one side of the air delivery pipe 129 away from the fixing tube 125 is fixedly connected to a diffusion chamber 1210 located on one side of the heat dissipation box 4.

[0063] When the limit plate 127 moves upward relative to the fixing tube 125, at this time, the heat dissipation box 4 is exposed accordingly. At the same time, the air inside the fixing tube 125 can be pressed out, and through the delivery of the air delivery pipe 129 and the diffusion chamber 1210, it directly acts on the inside of the heat dissipation box 4 for auxiliary cleaning. When the limit plate 127 moves downward relative to the fixing tube 125, a negative pressure can be generated inside the fixing tube 125, and external air is inhaled into the fixing tube 125 through the diffusion chamber 1210 and the air delivery pipe 129 for waiting for the next use.

[0064] Embodiment 4: As Figure 9 and Figure 11 and Figure 12 shown, the structure of this embodiment is basically the same as that of the above - mentioned embodiment. The difference is that the auxiliary support component 13 includes an L - shaped frame 131. One side of the L - shaped frame 131 is connected to the extension guide rail 6. The bottom end of the L - shaped frame 131 is fixedly connected with a longitudinal guide rail 132. A longitudinal block 133 is movably clamped inside the longitudinal guide rail 132. The auxiliary support component 13 also includes a mounting member 136 on one side, and the mounting member 136 is connected to the locking plate 11. The bottom ends of the longitudinal blocks 133 are fixedly installed with support rods 134. The bottom ends of the support rods 134 penetrate through the bottom end of the longitudinal guide rail 132 and are fixedly connected with suction cups 135. One side of the mounting member 136 close to the longitudinal guide rail 132 is fixedly connected with a third fixing seat 137. One side of the longitudinal block 133 close to the mounting member 136 is fixedly installed with a fourth fixing seat 138. A linkage rod 139 is movably connected between the third fixing seat 137 and the fourth fixing seat 138.

[0065] In the normal state, the displacement of the device can be controlled by the universal wheels 3. When the chassis is placed above the bottom plate 1, since the distance between the bottom plate 1 and the movable plate 121 is reduced, and due to the relative separation of the two locking plates 11, at this time, the two mounting members 136 can be driven to move relatively away from each other, and the linkage rod 139 can be driven to deflect obliquely downward. At this time, a downward pressure can be applied to the longitudinal latch 133, and the support rod 134 and the suction cup 135 can be driven to move downward until the suction cup 135 contacts the ground, replacing the support of the universal wheels 3 to complete the auxiliary fixing process.

[0066] By utilizing the cooperation between the linkage assembly 12 and the locking plate 11, and the cooperation between the locking plate 11 and the auxiliary support assembly 13, after the chassis is placed in place, the automatic descent of the suction cup 135 can be realized, replacing the support of the universal wheels 3 to complete the automatic auxiliary support process. After the chassis is installed in place, the entire device can be automatically fixed to the ground to prevent displacement, further improving the stability of the chassis.

[0067] A heat dissipation method for a heat dissipation support bracket of a computer, comprising the following steps:

[0068] S1: In the initial state, the device can be placed on a suitable horizontal ground, and the corresponding computer chassis can be placed down from the top of the device. At this time, the bottom end of the chassis can contact the inner sides of the two guiding inclined surfaces 706, and under the guiding action of the guiding inclined surfaces 706, the limiting spring 702 can be driven to be compressed. At this time, the two mounting plates 703 move relatively away from each other until the bottom end of the chassis contacts the bottom plate 1.

[0069] S2: At the same time, the limiting spring 702 automatically resets to drive the two mounting plates 703 to move relatively closer until the two limiting blocks 705 are driven to move relatively closer. By adjusting the height of the telescopic rod 704, the height adjustment of the limiting blocks 705 is completed until the inner sides of the limiting blocks 705 contact both sides of the top end of the chassis to complete the fixing process of the chassis.

[0070] S3: When the chassis is placed on the bottom plate 1, at this time, the bottom plate 1 moves downward, that is, drives the fixed pipe 125 to move downward. At this time, the return spring 128 is compressed, and the distance between the movable plate 121 and the heat dissipation box 4 is reduced. The connecting rod 124 deflects towards a position away from the middle and applies a pulling force to the two locking plates 11. At this time, the two locking plates 11 move relatively away from each other and drive the outer cleaning brush 9 and the inner cleaning brush 10 to move towards both sides, exposing the heat dissipation slots on the side of the heat dissipation box 4.

[0071] S4: By turning on the cooling fan 5, external air can be drawn into the interior of the cooling box 4 and enter the interior of the chassis through the ventilation slots 2 to achieve the intake operation. When the cooling box 4 becomes blocked, by removing the chassis, the linkage assembly 12 will automatically reset at this time, driving the outer cleaning brush 9 and the inner cleaning brush 10 to displace towards the middle of the cooling box 4 to clean the inner and outer sides of the cooling box 4, completing the self-cleaning process.

[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
