Description

Technical Field

[0001] The utility model relates to the technical field of bidirectional direct current power supplies, in particular to a programmable bidirectional direct current power supply. Background Art

[0002] A bidirectional DC power supply is a power supply that can provide both forward and reverse currents, and is often used to drive motors or other devices that require bidirectional currents. This power supply can provide adjustable voltage and current in both the forward and reverse directions, which can enable forward and reverse motor steering or other applications that require bidirectional currents. A bidirectional DC power supply usually consists of a power module and a controller, through which the voltage and current can be regulated and controlled. This type of power supply is widely used in industrial control, electric vehicles, ships and other fields. At present, programmable bidirectional DC power supplies often encounter height problems during use. When using a programmable bidirectional DC power supply, you need to bend down or squat to observe the digital display on the programmable bidirectional DC power supply, which is relatively troublesome to use, resulting in the inability to adjust the height of the programmable bidirectional DC power supply, which has become a problem affecting the use effect and experience of the programmable bidirectional DC power supply. At the same time, the programmable bidirectional DC power supply needs to be cooled during use, and the heat dissipation process easily causes the programmable bidirectional DC power supply to absorb dust. In order to prevent the programmable bidirectional DC power supply from being troubled by dust, the programmable bidirectional DC power supply usually needs to be equipped with a dustproof device. However, the dustproof device usually requires the corresponding tools to install and fix the bolts. When the dustproof device needs to be cleaned later, it needs to be disassembled and installed again after cleaning. The corresponding tools are required to operate during the process, and the disassembly and assembly are subject to certain influences and restrictions, which is not conducive to the maintenance and cleaning of the programmable bidirectional DC power supply, thereby affecting the use effect of the programmable bidirectional DC power supply and indirectly reducing the durability of the programmable bidirectional DC power supply.

[0003] Therefore, it is necessary to develop a programmable bidirectional DC power supply. Utility Model Content

[0004] The purpose of the utility model is to provide a programmable bidirectional DC power supply, which is provided with U-shaped legs and latches, and two groups of U-shaped legs are arranged in a support on the bidirectional DC power supply in a rotatable connection manner, so that the bidirectional DC power supply can be supported and placed by the support when it is in normal use. When the height of the bidirectional DC power supply needs to be increased, it is only necessary to rotate the corresponding two groups of U-shaped legs until the rubber pad contacts the plane, so that the height of the bidirectional DC power supply can be increased, and the situation that the height of the programmable bidirectional DC power supply cannot be adjusted and affects the use and experience is avoided as much as possible. By setting the latch in the mounting hole on the mounting plate by the limit column, and matching the spring on the outer wall of the limit column, when the dustproof plate is installed, it is only necessary to push the dustproof plate onto the bidirectional DC power supply. The two groups of L-shaped card plates are interposed between the two groups. During the pushing process, the pin is subjected to the reaction force of the spring and is inserted into the slot on the L-shaped card plate, so that the dustproof plate can be installed and fixed. When the dustproof plate needs to be disassembled and cleaned later, only a little force needs to be applied to push the dustproof plate until the pin is forced to disengage from the slot, and the dustproof plate can be disassembled. The disassembly and assembly process is relatively simple and convenient for disassembly and assembly operations, and the situation that the dustproof plate on the programmable bidirectional DC power supply is difficult to disassemble and affects the maintenance and cleaning efficiency is avoided as much as possible. The use effect of the programmable bidirectional DC power supply is effectively improved, and the durability of the programmable bidirectional DC power supply is indirectly improved, so as to solve the problem that the programmable bidirectional DC power supply has poor effect and affects durability and use proposed in the above background technology.

[0015] By providing U-shaped legs and latches, two groups of U-shaped legs are rotatably connected and arranged in a support on the bidirectional DC power supply, so that the bidirectional DC power supply can be supported and placed by the support when it is in normal use. When the height of the bidirectional DC power supply needs to be increased, it is only necessary to rotate the corresponding two groups of U-shaped legs until the rubber pads contact the plane to increase the height of the bidirectional DC power supply, thereby avoiding the situation where the height of the programmable bidirectional DC power supply cannot be adjusted and affects the use and experience.

[0016] By setting the pin in the mounting hole on the mounting plate by the limit column and matching it with the spring on the outer wall of the limit column, when installing the dustproof plate, it is only necessary to push the dustproof plate between the two groups of L-shaped card plates on the bidirectional DC power supply. During the pushing process, the pin is subjected to the reaction force of the spring and is inserted into the slot on the L-shaped card plate, so that the dustproof plate can be installed and fixed.

[0024] Dust-proof plates 3 are installed at the center of the outer walls on both sides of the bidirectional DC power supply 1. The outer wall surfaces on both sides of the dust-proof plates 3 are provided with installation grooves 301. The dust-proof plates 3 are located between the opposite sides of the two groups of L-shaped card plates 101. The top and bottom of the dust-proof plates 3 are slidably connected with the inside of the two groups of L-shaped card plates 101. The two groups of dust-proof plates 3 are pushed into the two groups of L-shaped card plates 101 on the bidirectional DC power supply 1 in a sliding manner. The dust-proof plates 3 can be pushed in or pulled out to achieve the installation and removal effect. At the same time, the installation of the dust-proof plates 3 is as far as possible. In order to prevent dust from entering the interior of the bidirectional DC power supply 1 and causing certain damage to the interior, a mounting plate 4 is installed inside the mounting groove 301, a mounting hole 401 is opened at the center of the surface of the mounting plate 4, a limiting column 402 is installed inside the mounting hole 401, and the outer wall of the limiting column 402 is slidably connected to the inside of the mounting hole 401. The limiting column 402 is slidably set in the mounting hole 401 on the mounting plate 4, so that the limiting column 402 can be moved leftward or rightward on the mounting plate 4, and the limiting column 402 can be moved leftward or rightward on the mounting plate 4.

When the height of the bidirectional DC power supply 1 needs to be increased, it is only necessary to rotate the corresponding two sets of U-shaped legs 201 until the rubber pads 202 contact the plane to increase the height of the bidirectional DC power supply 1, and try to avoid the situation where the programmable bidirectional DC power supply cannot be adjusted in height and affects the use and experience. At the same time, the U-shaped legs 201 and the support The rotating area between the seats 2 can be damped to avoid the U-shaped legs 201 rotating too flexibly inside the support 2 and affecting the normal upright state of the U-shaped legs 201.

At the same time, the installation of the dustproof plates 3 can avoid dust from entering the interior of the bidirectional DC power supply 1 as much as possible, and causing certain damage to the interior. By installing and fixing the mounting plate 4 in the mounting groove 301 on the dustproof plate 3 The limiting column 402 is set in the mounting hole 401 on the mounting plate 4 in a sliding manner, so that the limiting column 402 can be moved left or right on the mounting plate 4, by sequentially setting a limiting ring 403 and a latch 404 at both ends of the limiting column 402, and setting a spring 405 on the outer wall of the limiting column 402, using the effect of the reaction force of the spring 405, cooperating with one end of the latch 404 in an arc state, when the dustproof plate 3 is pushed between the two groups of L-shaped card plates 101, the latch 404 is squeezed, the spring 405 contracts and deforms, and the latch 404 moves to the slot on the L-shaped card plate 101. 102, spring 405 is unpressed, pushing pin 404 into slot 102, thereby achieving installation and fixing of dustproof plate 3.

The disassembly and assembly process is relatively simple and convenient for disassembly and assembly operations, and the situation that the dustproof plate on the programmable bidirectional DC power supply is difficult to disassemble and affects the maintenance and cleaning efficiency is avoided as much as possible, which effectively improves the use effect of the programmable bidirectional DC power supply and indirectly improves the durability of the programmable bidirectional DC power supply.
