DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Example: Reference Figure 1-Figure 11 A UPS power supply with high heat dissipation includes a base 101, on which three batteries 110 are fixedly installed, and on which an auxiliary shell 102 is also fixedly installed. An unfolding component is arranged between the base 101 and the auxiliary shell 102, and the unfolding component includes two L-shaped covering rotating plates 106 symmetrically rotatably installed on the base 101, and the two L-shaped covering rotating plates 106 are used to cover and protect the electrical components on the base 101, and the L-shaped covering rotating plates 106 are rotatably connected to the auxiliary shell 102, and a torsion spring is arranged between the L-shaped covering rotating plates 106 and the base 101, one end of the torsion spring is fixedly connected to the base 101, and the other end of the torsion spring is fixedly connected to the L-shaped covering rotating plates 106.

[0027] In the initial position, the torsion spring between the base 101 and the L-shaped cover rotating plate 106 is not compressed. At this time, the end faces of the two L-shaped cover rotating plates 106 are in contact. At this time, an installation chamber for electrical components is formed between the base 101, the auxiliary shell 102, and the L-shaped cover rotating plate 106. A controller 111 is also fixedly installed on the base 101. The battery 110 and the controller 111 are both located inside the installation chamber. A wiring panel 104 and a display panel 105 are also fixedly installed on the end face of the base 101.

[0028] The L-shaped covering rotating plate 106 is driven to rotate relative to the base 101, and the torsion spring between the base 101 and the L-shaped covering rotating plate 106 is compressed, so that the two L-shaped covering rotating plates 106 rotate away from each other, and finally the two L-shaped covering rotating plates 106 are rotated 90 degrees. At this time, the two L-shaped covering rotating plates 106 are in a horizontal state, that is, the L-shaped covering rotating plate 106 releases the covering protection of the battery 110 and the controller 111 on the base 101. At this time, the battery 110 and the controller 111 on the base 101 are exposed to the outside, thereby facilitating the maintenance of the battery 110 and the controller 111.

[0029] The L-shaped cover rotating plate 106 is rotatably mounted with an L-shaped heat dissipation rotating plate 107, a torsion spring is arranged between the L-shaped cover rotating plate 106 and the L-shaped heat dissipation rotating plate 107, one end of the torsion spring is fixedly connected to the L-shaped cover rotating plate 106, and the other end of the torsion spring is fixedly connected to the L-shaped heat dissipation rotating plate 107, a louver plate 108 is fixedly arranged on the L-shaped heat dissipation rotating plate 107, and a heat dissipation fan 135 is symmetrically fixedly mounted on the L-shaped cover rotating plate 106, and the heat dissipation fan 135 is used to dissipate heat from the installation chamber. The cover rotating plate 106 is also provided with a filter plate 112 and a filter plate 2 133. The filter plate 112 and the bolt 113 on the same L-shaped cover rotating plate 106 are vertically arranged. The bolt 113 is symmetrically arranged between the filter plate 112 and the bolt 113 and the L-shaped cover rotating plate 106. The filter plate 112 and the bolt 113 are fixedly connected to the L-shaped cover rotating plate 106 by the bolt 113. The filter plate 112 is located between the louver 108 and the cooling fan 135.

[0030] When the L-shaped covering rotating plate 106 is driven to rotate relative to the base 101, the L-shaped heat dissipation rotating plate 107 rotates synchronously, driving the L-shaped heat dissipation rotating plate 107 to rotate relative to the L-shaped covering rotating plate 106, the torsion spring between the L-shaped covering rotating plate 106 and the L-shaped heat dissipation rotating plate 107 is compressed, and the two L-shaped heat dissipation rotating plates 107 rotate in opposite directions, and finally the two L-shaped heat dissipation rotating plates 107 are rotated to a horizontal state. At this time, the filter plate 1 112 and the filter plate 2 133 are both located in the external environment, thereby increasing the ventilation effect of the installation chamber, thereby improving the heat dissipation effect inside the installation chamber.

[0031] The controller 111 is used to control the cooling fan 135, so that the cooling fan 135 rotates to dissipate heat inside the installation chamber. When the louver 108 cannot meet the ventilation requirements, the two L-shaped cooling rotating plates 107 rotate in a direction away from the base 101, so that the L-shaped cooling rotating plate 107 releases the cover on the filter plate 112 and the bolt 113, thereby improving the ventilation effect of the installation chamber. Dust is easily accumulated on the filter plate 112 and the filter plate 2 133, so the L-shaped cooling rotating plate 107 releases the cover on the filter plate 112 and the filter plate 2 133, which can facilitate cleaning of the dust accumulated on the filter plate 112 and the filter plate 2 133. The two L-shaped covering rotating plates 106 can also be unfolded, the bolt 113 can be removed, and the filter plate 112 and the filter plate 2 133 can be replaced.

[0032] Two positioning components are symmetrically arranged on the auxiliary shell 102. The side surfaces of the L-shaped covering rotating plate 106 are fixedly installed with the unfolding gear 2 122. The center line of the rotation connection between the L-shaped covering rotating plate 106 and the base 101 is in the same straight line with the axis of the corresponding unfolding gear 2 122. The side surfaces of the L-shaped heat dissipation rotating plate 107 are fixedly installed with the unfolding gear 1 117. The center line of the rotation connection between the L-shaped heat dissipation rotating plate 107 and the L-shaped covering rotating plate 106 is in the same straight line with the axis of the corresponding unfolding gear 1 117. The positioning components are used to adjust and limit the positions of the corresponding unfolding gear 2 122 and the unfolding gear 1 117.

[0033] The positioning components all include a three-arm rotating plate 119 rotatably mounted on the auxiliary housing 102, a torsion spring is arranged between the three-arm rotating plate 119 and the auxiliary housing 102, one end of the torsion spring is fixedly connected to the auxiliary housing 102, and the other end of the torsion spring is fixedly connected to the three-arm rotating plate 119, a sector rack 121 is fixedly arranged on the three-arm rotating plate 119, and the sector rack 121 forms a gear rack pair when meshing with the unfolding gear 1 117, and forms a gear rack pair when meshing with the unfolding gear 2 122.

[0034] A fan-shaped short strip 120 and a fan-shaped long strip 124 are also fixedly arranged on the three-arm rotating plate 119, and the circumferential directions of the fan-shaped short strip 120 and the fan-shaped long strip 124 are the same. A transmission round block 118 is fixedly installed on the unfolding gear 117, and a transmission round block 2 123 is fixedly installed on the unfolding gear 122. The transmission round block 118 is provided with an arc-shaped slide groove 131 that cooperates with the fan-shaped short strip 120, and the transmission round block 2 123 is provided with an arc-shaped slide groove 2 132 that cooperates with the fan-shaped long strip 124.

[0035] In the initial position, the torsion spring between the three-arm rotating plate 119 and the auxiliary shell 102 is not compressed. At this time, the fan-shaped rack 121 is not in contact with the unfolding gear 117 and the unfolding gear 2 122. The fan-shaped short strip plate 120 and the arc-shaped slide groove 131 on the transmission round block 118 are in a engaged state, and the fan-shaped long strip plate 124 and the arc-shaped slide groove 2 132 on the transmission round block 2 123 are in a engaged state. Under the action of the transmission round block 118 and the fan-shaped short strip plate 120, the L-shaped heat dissipation rotating plate 107 cannot rotate relative to the L-shaped covering rotating plate 106. Under the action of the transmission round block 2 123 and the fan-shaped long strip plate 124, the L-shaped covering rotating plate 106 cannot rotate relative to the auxiliary shell 102.

[0036] The three-arm rotating plate 119 is driven to rotate relative to the auxiliary housing 102, and the torsion spring between the auxiliary housing 102 and the three-arm rotating plate 119 is compressed, so that the short sector plate 120 is disengaged from the arc-shaped slide groove 131 on the transmission round block 118, and the long sector plate 124 is still in engagement with the arc-shaped slide groove 132, and the sector rack 121 is in contact with the expansion gear 117, and the three-arm rotating plate 119 continues to rotate. Under the action of the sector rack 121, the expansion gear 117 rotates, that is, the L-shaped heat dissipation rotating plate 10 7 rotates relative to the L-shaped covering rotating plate 106. At this time, the unfolding gear 2 122 cannot rotate under the action of the transmission round block 2 123 and the fan-shaped long strip plate 124, that is, the position of the L-shaped covering rotating plate 106 is always in a fixed state. Under the action of the fan-shaped rack 121 and the unfolding gear 1 117, the L-shaped heat dissipation rotating plate 107 is finally rotated 90 degrees to a horizontal state, that is, the L-shaped heat dissipation rotating plate 107 is fully unfolded. At this time, the fan-shaped long strip plate 124 is still in an engaged state with the arc-shaped slide groove 2 132 on the transmission round block 2 123.

[0037] The three-arm rotating plate 119 is driven to rotate relative to the auxiliary shell 102, and the torsion spring between the auxiliary shell 102 and the three-arm rotating plate 119 is compressed, so that the fan-shaped long strip plate 124 is disengaged from the arc-shaped slide groove 132 on the transmission round block 123. At this time, the fan-shaped short strip plate 120 is disengaged from the arc-shaped slide groove 131 on the transmission round block 118, and the fan-shaped rack 121 is in contact with the unfolding gear 2 122. The three-arm rotating plate 119 continues to rotate. Under the action of the fan-shaped rack 121, the unfolding gear 2 122 rotates, that is, the L-shaped covering rotating plate 106 is rotated relative to the base 101, and the L-shaped heat dissipation rotating plate 107 on the L-shaped covering rotating plate 106 is synchronously rotated under the action of the torsion spring between the L-shaped covering rotating plate 106 and the L-shaped heat dissipation rotating plate 107, and finally the L-shaped covering rotating plate 106 is rotated 90 degrees to a horizontal state, that is, the L-shaped covering rotating plate 106 is fully unfolded.

[0038] That is, by controlling the forward and reverse rotation of the same three-arm rotating plate 119, the unfolding gear 1 117 and the unfolding gear 2 122 are respectively rotated, that is, the L-shaped covering rotating plate 106 and the L-shaped heat dissipating rotating plate 107 are respectively rotated.

[0039] The auxiliary housing 102 is also fixedly mounted with a strip support plate 125, and the three-arm rotating plates 119 are all rotatably connected to the strip support plate 125. A transmission gear 126 is fixedly mounted on one of the two three-arm rotating plates 119. The auxiliary housing 102 is also fixedly mounted with a positioning motor 114, which is not installed inside the chamber. The output shaft of the positioning motor 114 is fixedly connected to the three-arm rotating plate 119 without the transmission gear 126. The strip support plate 125 is also rotatably mounted with a driven gear 127, the driving gear 126 and the driven gear 127 are meshed to form a gear pair, and a transmission group is arranged between the driven gear 127 and the three-arm rotating plate 119 without the driving gear 126, and the transmission group includes a driven pulley 128, a driving pulley 129, and a driving belt 130. The driven pulley 128 is fixedly mounted on the driven gear 127, the driving pulley 129 is fixedly mounted on the three-arm rotating plate 119 without the driving gear 126, and the driving belt 130 is arranged between the driven pulley 128 and the driving pulley 129.

[0040] Start the positioning motor 114 to drive the corresponding three-arm rotating plate 119 to rotate. Under the action of the driven pulley 128, the transmission pulley 129 and the transmission belt 130, the driven gear 127 rotates synchronously, thereby causing the transmission gear 126 to rotate. The rotation directions of the transmission gear 126 and the driven gear 127 are opposite, and the three-arm rotating plates 119 corresponding to the transmission gear 126 rotate synchronously, that is, the two three-arm rotating plates 119 rotate in opposite directions, thereby facilitating the synchronous adjustment of the two L-shaped covering rotating plates 106 and the two L-shaped heat dissipation rotating plates 107. When the fan-shaped rack 121 drives the unfolding gear 117 to rotate, the two L-shaped heat dissipation rotating plates 107 rotate in opposite directions, and finally the two L-shaped heat dissipation rotating plates 107 are in a horizontal state. When the fan-shaped rack 121 drives the unfolding gear 2 122 to rotate, the two L-shaped covering rotating plates 106 rotate in opposite directions, and finally the two L-shaped covering rotating plates 106 are in a horizontal state.

[0041] A cover plate 103 is also provided on the auxiliary shell 102, three bolts 115 are provided between the auxiliary shell 102 and the cover plate 103, sleeve rods 134 are symmetrically fixedly provided on the auxiliary shell 102, another sleeve rod 134 is fixedly installed on the strip support plate 125, the auxiliary shell 102 and the cover plate 103 are fixedly connected by bolts 115 and the sleeve rod 134, and a supplementary shell 109 is fixedly provided on the L-shaped heat dissipation rotating plate 107. When the auxiliary shell 102, the cover plate 103 and the supplementary shell 109 are joined, a protective chamber is formed, and the parts of the adjustment assembly are all located inside the protective chamber.

[0042] A hexagonal block 116 is also fixedly installed on the three-arm rotating plate 119 on which the transmission gear 126 is fixedly installed. A through hole cooperating with the hexagonal block 116 is provided on the cover plate 103. The hexagonal block 116 is used to manually adjust the positioning assembly. When the positioning motor 114 cannot move the L-shaped covering rotating plate 106 and the L-shaped heat dissipating rotating plate 107, the hexagonal block 116 can be rotated by engaging the handle cooperating with the hexagonal block 116 with the hexagonal block 116 and then rotating the handle, thereby rotating the hexagonal block 116 and only rotating the three-arm rotating plate 119, thereby manually adjusting the positions of the L-shaped covering rotating plate 106 and the L-shaped heat dissipating rotating plate 107.

[0043] Working principle: The controller 111 controls the cooling fan 135 to achieve heat dissipation inside the installation chamber, that is, to achieve heat dissipation inside the device. When the louver 108 cannot meet the ventilation volume requirement, the two L-shaped heat dissipation rotating plates 107 are rotated relative to the corresponding L-shaped covering rotating plates 106 through the adjustment component, thereby increasing the ventilation volume of the installation chamber, thereby improving the heat dissipation effect, and dust is intercepted under the action of filter plate 1 12 and filter plate 2 133.

[0044] When too much dust accumulates on the filter plate 1 112 and the filter plate 2 133, the two L-shaped heat dissipation rotating plates 107 can be rotated to a horizontal state relative to the L-shaped covering rotating plate 106, thereby facilitating cleaning of the dust on the filter plate 112 and the bolt 1 13. The two L-shaped covering rotating plates 106 can also be rotated to a horizontal state relative to the base 101 through the adjustment component, so that the filter plate 112 and the filter plate 2 133 can be replaced by removing the bolt 113.

[0045] When the battery 110 and the controller 111 need to be inspected, the two L-shaped cover rotating plates 106 are rotated to a horizontal state relative to the base 101 through the adjustment component, that is, the L-shaped cover rotating plates 106 release the covering protection of the battery 110 and the controller 111, thereby facilitating the inspection of the parts and electrical components on the base 101.

[0046] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
