Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example: Figure 1-8As shown, the present invention provides a power supply chassis with high efficiency in heat dissipation and dust removal, including a power supply chassis main body 1, a supporting mechanism 2 is arranged at the center of one side of the power supply chassis main body 1, a reciprocating mechanism 3 is arranged on one side of the supporting mechanism 2, a mounting mechanism 4 is arranged on one side of the reciprocating mechanism 3, a driving mechanism 5 is arranged on one side of the mounting mechanism 4, the reciprocating mechanism 3 and the mounting mechanism 4 are both in contact with the power supply chassis main body 1, heat dissipation and dust removal mechanisms 6 are symmetrically arranged at both ends of one side of the power supply chassis main body 1, and the heat dissipation and dust removal mechanisms 6 are connected to the reciprocating mechanism 3; through the supporting mechanism 2, the reciprocating mechanism 3 can be facilitated to work normally, through the reciprocating mechanism 3, it is convenient to drive part of the structure of the heat dissipation and dust removal mechanism 6 to move, thereby further improving the heat dissipation effect of the heat dissipation and dust removal mechanism 6, through the mounting mechanism 4, it is convenient to install and fix the driving mechanism 5, and through the driving mechanism 5, power is provided for the normal operation of the reciprocating mechanism 3.

[0027] The heat dissipation and dust removal mechanism 6 includes a fixed block 61 and a vacuum box 62. Connecting rods 63 are symmetrically fixed on the top and bottom of the fixed block 61. One end of the connecting rod 63 passes through the vacuum box 62 and is fixed with a piston plate 64. The outer wall of the piston plate 64 slides with the inner wall of the vacuum box 62, and the piston plate 64 is close to the bottom of the inner wall of the vacuum box 62. One side of the vacuum box 62 is fixed with the corner of the power supply chassis body 1.

[0028] By adopting the above technical solution, when the fixed block 61 moves with the movement of the reciprocating mechanism 3, it drives the piston plate 64 to move close to the vacuum box 62, changes the air pressure inside the vacuum box 62, and provides power for the heat dissipation and dust removal mechanism 6 to dissipate heat and remove dust.

[0029] The two ends of the bottom of the vacuum box 62 are symmetrically connected with conduits 65, and a one-way valve 66 is installed on the surface of the conduit 65. The bottom end of one of the conduits 65 located at the top is connected with a first hose 67, and one end of the first hose 67 is connected with an exhaust pipe 68. The bottom end of the exhaust pipe 68 is connected with an intermediate box 69, and the bottom end of the intermediate box 69 is connected with an air intake pipe 610.

[0030] By adopting the above technical solution, when the fixed block 61 moves upward, it drives the piston plate 64 located above to move upward, reducing the air pressure inside the corresponding vacuum box 62, and the hot air and dust around the power supply chassis body 1 enter the vacuum box 62 through the first hose 67 and the corresponding conduit 65, thereby achieving the purpose of heat dissipation and dust removal of the power supply chassis body 1 and extending the service life of the power supply.

At the same time, a retractable dust cover (accordion cover) can also be connected between the U-shaped reciprocating plate 34 and the avoidance groove 71, so that the U-shaped reciprocating plate 34 can maintain the sealing of the avoidance groove 71 during the sliding process.

[0039] The two opposite connection surfaces of the power supply chassis body 1 are provided with threaded holes 12, that is, Figure 1The top and bottom surfaces of the power supply chassis body 1 are the connection surfaces, and the cover plate 7 wraps the connection surfaces. The cover plate 7 is provided with connection holes 72 corresponding to the threaded holes 12, and a positioning bar 11 is also provided on the connection surface. The positioning bar 11 is located on the side of the threaded hole 12 away from the cover plate 7. The cover plate 7 is sleeved with the power supply chassis body 1.

[0040] By adopting the above technical solution, when the driving mechanism 5 drives the rack 32 to move, it further drives the reciprocating rod 31, the connecting block 33 and the U-shaped reciprocating plate 34 to reciprocate.

[0041] The driving mechanism 5 includes a motor 51, and a first rotating shaft 52 is fixedly provided at the output end of the motor 51 through the through hole 43.

The second spur gear 54 is mounted on the second rotating shaft 55. One end of the second rotating shaft 55 is rotatably matched with the other end of the mounting plate 41. A fan gear 56 is mounted on the surface of the second rotating shaft 55, and the fan gear 56 is meshed with the rack 32.

[0042] By adopting the above technical solution, when the power supply chassis body 1 needs to be cooled, the motor 51 is started to rotate, thereby driving the first spur gear 53 and the second spur gear 54 to rotate, and then driving the fan gear 56 to rotate, and the fan gear 56 alternately drives the corresponding rack 32 to move back and forth.

[0047] Working principle:

[0048] When the power supply chassis main body 1 needs to be cooled and dusted, when the fixed block 61 moves upward, the piston plate 64 located above is driven to move upward, reducing the internal air pressure of the vacuum box 62, and the hot air and dust around the power supply chassis main body 1 flow through the filter 612, the intermediate box 69, the first hose 67 and the conduit 65 into the vacuum box 62. At the same time, the external low-temperature air flows through the corresponding conduit 65 and the one-way valve 66 below and enters the vacuum box 62 below; when the fixed block 61 moves downward, the hot air is ejected from another conduit 65 located above, and the conduit 65 is connected to an external pipeline to exhaust the hot air and dust. At the same time, the low-temperature air flows through another conduit 65 located below, the second hose 611 and the air inlet pipe 610 into the intermediate box 69, and is ejected from the filter 612 to cool down the area around the power supply chassis main body 1, and so on. The purpose of heat dissipation and dust removal of the power supply chassis main body 1 is achieved, and the service life of the power supply is extended.

[0049] When the power supply chassis main body 1 is to be cooled and dusted, the motor 51 is started to rotate, thereby driving the first spur gear 53 and the second spur gear 54 to rotate, and then driving the fan gear 56 to rotate. The fan gear 56 alternately drives the corresponding rack 32 to move back and forth, thereby driving the reciprocating rod 31, the connecting block 33 and the U-shaped reciprocating plate 34 to move back and forth, and then driving the intermediate box 69 to move back and forth, so that the heat dissipation and dust removal mechanism 6 can absorb the hot air and dust in the power supply chassis main body 1 at multiple locations in the power supply chassis and transport low-temperature air into the power supply chassis main body. One driving mechanism drives to complete multiple different functional effects of heat dissipation and dust removal of the power supply chassis.
