DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 4 : An intelligent high-frequency switching DC power supply device, comprising a frame 1, on which at least two power supply modules 2 are arranged, and the plurality of power supply modules 2 are distributed in a matrix, and the frame 1 is provided with a power grid for connecting the plurality of power supply modules 2; the power supply module 2 comprises a mounting frame 21, a movable block 22 and a first elastic member 23; the mounting frame 21 is slidably mounted on the frame 1, and a working station and a maintenance station are arranged on the frame 1. In a working state, as the mounting frame 21 slides, the mounting frame 21 can switch between the working station and the maintenance station; a power supply unit 211 is detachably mounted on the mounting frame 21; a first mounting seat 212 is mounted on the mounting frame 21; the movable block 22 A slope is provided on it and it is slidably installed on the first mounting seat 212; docking pieces 221 and power plug 222 are respectively provided on both sides of the movable block 22; the two ends of the first elastic member 23 are respectively connected to the first mounting seat 212 and the movable block 22; in the process of installing the power supply unit 211, the power supply unit 211 squeezes the slope of the movable block 22, overcomes the elastic force of the first elastic member 23 and pushes the movable block 22; after the power supply unit 211 is installed, the power supply unit 211 is electrically connected to the power plug 222 through the docking piece 221, and after the mounting frame 21 slides to the working position, the power plug 222 of the movable block 22 is just electrically connected to the power grid on the rack 1.

[0032] The present invention realizes the function of automatically controlling the opening and closing of the circuit board according to the disassembly and assembly status of the power supply unit 211 through the rack 1 and the power supply module 2, so as to achieve the effect of automatically disconnecting the circuit board at the corresponding position when the power supply unit 211 is not fully installed, and solves the problem that the circuit board may not be closed when the traditional power supply device is disassembling and assembling the power supply unit 211. When installing the power supply unit 211, the operator first pulls out the mounting frame 21 and moves it to the maintenance station. The power supply unit 211 squeezes the inclined surface of the movable block 22 to overcome the elastic force of the first elastic member 23 to push the movable block 22. When the power supply unit 211 is installed, the power supply unit 211 and the docking piece 221 of the movable block 22 are tightly matched. Then the operator slides the mounting frame 21 and moves the mounting frame 21 to the working station. The mounting frame 21 drives the power plug 222 to move, and the power supply unit 211 is connected to the power grid on the rack 1 through the docking piece 221 and the power plug 222. When disassembling the power supply unit 211, the operator slides out the mounting frame 21, thereby controlling the power plug 222 to separate from the power grid, thereby preventing the disassembly and assembly of the power supply unit 211 from affecting the power grid, and then removes the power supply unit 211 from the mounting frame 21. As the power supply unit 211 separates from the movable block 22, the movable block 22 automatically moves away from the rack 1 under the elastic force of the first elastic member 23. Even if the empty mounting frame 21 is pushed into the working station, the power plug 222 will not be connected to the power grid, thereby avoiding affecting the power grid.

[0033] Reference Figure 1-Figure 4 : The frame 1 is also provided with an auxiliary control mechanism 3 and a limiting mechanism 4, the auxiliary control mechanism 3 includes a nitrogen spring 31, a first fixing component 32 and a first control component 33; the nitrogen spring 31 is installed on the frame 1 and its piston rod is connected to the mounting frame 21; the first fixing component 32 is arranged on the first mounting seat 212 and is used to limit the movement of the first mounting seat 212; the first control component 33 is arranged on the mounting frame 21 and is used to control the opening and closing of the first fixing component 32; the limiting mechanism 4 includes a second fixing component 41 and a second control component 42; the second fixing component 41 is arranged on the mounting frame 21 and is used to limit the movement of the mounting frame 21; the second control component 42 is arranged on the mounting frame 21 and is used to control the opening and closing of the second fixing component 41; in the working state, when the mounting frame 21 is located at the working station, the second fixing component 41 limits the movement of the mounting frame 21; when the mounting frame 21 is located at the maintenance station, the first fixing component 32 limits the movement of the first mounting seat 212.

[0034] The present invention realizes the function of controlling the rapid disassembly and assembly of the mounting frame 21 through the nitrogen spring 31, the first fixing component 32 and the first control component 33, so as to achieve the effect of quickly moving the mounting frame 21 from the working station to the maintenance station. Usually, the high-frequency switching DC power supply device can monitor the operating status of each power supply unit 211 in the rack 1, such as voltage, current, temperature, internal resistance, remaining power, etc., accurately predict battery failure and abnormality, and ensure the stability and reliability of the DC system. During operation, once the high-frequency switching DC power supply device finds that the power supply unit 211 fails, a feedback signal is sent to the controller. After receiving the signal, the operator releases the restriction of the second fixing component 41 on the movement of the mounting frame 21 through the second control component 42. The mounting frame 21 moves from the working station to the maintenance station under the elastic force of the nitrogen spring 31. At this time, the first fixing component 32 restricts the movement of the first mounting seat 212, and then fixes the mounting frame 21 at the maintenance station until the operator completes the maintenance of the power supply unit 211. Then, the first control component 33 is used to release the restriction of the movement of the first fixing component 32 on the first mounting seat 212, and the elastic force of the nitrogen spring 31 is overcome to push the mounting frame 21 to the working station. The constant force drive of the nitrogen spring 31 makes the ejection speed of the mounting frame 21 relatively constant, so as to prevent the power supply unit 211 from being subjected to a large impact.

[0035] Reference Figure 2 , Figure 4 and Figure 5 : The first fixing component 32 includes a first bracket 321, a first block 322 and a second elastic member 323; the first bracket 321 is installed on the frame 1; the first block 322 is slidably installed on the first bracket 321; the two ends of the second elastic member 323 are respectively connected to the first block 322 and the first bracket 321; the first mounting seat 212 is provided with a slot 324 that cooperates with the first block 322.

[0036] The present invention realizes the function of limiting the movement of the first mounting seat 212 through the first bracket 321, the first clamping block 322, the second elastic member 323 and the clamping slot 324. After the operator finds that the power supply unit 211 is faulty, the operator releases the restriction of the second fixing assembly 41 on the movement of the mounting frame 21 through the second control assembly 42, and the mounting frame 21 moves from the working station to the maintenance station under the elastic force of the nitrogen spring 31. At this time, the first fixing assembly 32 limits the movement of the first mounting seat 212, and then fixes the mounting frame 21 at the maintenance station until the operator completes the maintenance of the power supply unit 211, and then controls the movement of the first clamping block 322 through the first control assembly 33, overcomes the elastic force of the second elastic member 323 to drive the first clamping block 322 away from the clamping slot 324, releases the restriction of the movement of the first mounting seat 212 by the first fixing assembly 32, and overcomes the elastic force of the nitrogen spring 31 to push the mounting frame 21 to the working station.

[0037] Reference Figure 4 and Figure 6 : The first control component 33 includes a control rod 331 and an oblique control block 332; the control rod 331 is slidably installed on the first mounting seat 212; the end of the control rod 331 away from the card slot 324 is connected to the oblique control block 332; in the working state, the mounting frame 21 is located at the maintenance station, and when the first mounting seat 212 is restricted in movement by the first fixed component 32, the movable block 22 is squeezed by the power supply unit 211, and the movable block 22 squeezes the oblique control block 332, and the oblique control block 332 drives the control rod 331 to move, and the control rod 331 pushes the first card block 322, so that the first card block 322 is separated from the card slot 324.

[0038] The present invention realizes the function of controlling the opening and closing of the first fixed component 32 through the control rod 331 and the oblique control block 332. After the operator finds that the power supply unit 211 is faulty, the operator releases the restriction of the second fixed component 41 on the movement of the mounting frame 21 through the second control component 42. The mounting frame 21 moves from the working station to the maintenance station under the elastic force of the nitrogen spring 31. The operator removes the power supply unit 211, and the movable block 22 is reset under the elastic force of the first elastic member 23. The first clamping block 322 is clamped into the clamping slot 324 under the elastic force of the second elastic member 323, and the control rod 331 is pushed out of the clamping slot 324 from the other end of the clamping slot 324. At this time, the first fixed component 32 controls the movement of the first mounting seat 212. The restriction is then fixed to the maintenance station. When the operator completes the maintenance of the power supply unit 211, the power supply unit 211 is installed in the mounting frame 21 again. After the movable block 22 is squeezed by the power supply unit 211, the movable block 22 squeezes the oblique control block 332. The oblique control block 332 drives the control rod 331 to move. The control rod 331 pushes the first clamping block 322 to separate the first clamping block 322 from the clamping slot 324, thereby releasing the movement restriction of the first fixing component 32 on the first mounting seat 212, overcoming the elastic force of the nitrogen spring 31, and pushing the mounting frame 21 to the working station.

[0039] Reference Figure 4 and Figure 6 : The auxiliary control mechanism 3 also includes a guide assembly 34, which includes an extension block 341, a guide rod 342 and a return spring 343; the extension block 341 is arranged on the oblique control block 332; the guide rod 342 is installed on the first mounting seat 212; and the two ends of the return spring 343 are respectively connected to the extension block 341 and the mounting seat.

[0040] The present invention realizes the function of guiding the movement of the oblique control block 332 through the extension block 341, the guide rod 342 and the reset spring 343, and at the same time, the reset spring 343 is used to control the reset of the oblique control block 332 and the control rod 331. When the operator completes the maintenance of the power supply unit 211, the power supply unit 211 is installed in the mounting frame 21. After the movable block 22 is squeezed by the power supply unit 211, the movable block 22 overcomes the elastic force of the reset spring 343 to squeeze the oblique control block 332, and the oblique control block 332 drives the control rod 331 to move. The control rod 331 pushes the first clamping block 322, so that the first clamping block 322 is separated from the clamping slot 324, and the movement restriction of the first fixing component 32 on the first mounting seat 212 is released, and the elastic force of the nitrogen spring 31 is overcome to push the mounting frame 21 to the working station. The movement of the oblique control block 332 is guided by the sliding cooperation between the extension block 341 and the guide rod 342. At the same time, after the power supply unit 211 and the movable block 22 are separated, the oblique control block 332 and the control rod 331 are quickly reset under the elastic force of the reset spring 343, avoiding the control rod 331 from affecting the cooperation between the first block 322 and the slot 324.

[0041] Reference Figure 3 , Figure 5 and Figure 7 : The second fixing component 41 includes a second mounting seat 411, a second clamping block 412, a third elastic member 413 and a buckle 414; the second mounting seat 411 is installed on the mounting frame 21; the second clamping block 412 is slidably installed on the second mounting seat 411; the two ends of the third elastic member 413 are respectively connected to the second mounting seat 411 and the second clamping block 412; the buckle 414 is arranged on the first bracket 321.

[0042] The present invention realizes the function of limiting the movement of the mounting frame 21 through the second mounting seat 411, the second clamping block 412, the third elastic member 413 and the buckle 414. After the operator finds that the power supply unit 211 is faulty, the operator overcomes the elastic force of the third elastic member 413 through the second control component 42, controls the second clamping block 412 to separate from the buckle 414, and releases the restriction of the movement of the mounting frame 21 by the second fixing component 41. The mounting frame 21 moves from the working station to the maintenance station under the elastic force of the nitrogen spring 31, and then the first fixing component 32 restricts the movement of the first mounting seat 212.

[0044] The present invention realizes the function of controlling the movement of the second clamping block 412 through the connecting frame 421, the push plate 422 and the oblique guide groove 423.
