Description

Technical Field

[0001] This utility model relates to the field of power supplies, and more particularly to synchronous rectification and commutation power supplies. Background Technology

[0002] Synchronous rectification is a new technology that uses dedicated power MOSFETs with extremely low on-state resistance to replace rectifier diodes in order to reduce rectification losses. Synchronous rectification commutation power supplies are also a type of equipment power supply. Commutation means reversing the positive and negative terminals of the power supply output. Power supplies with this function are called commutation power supplies. There are two specific commutation methods: mechanical commutation and electronic commutation. The mechanical commutation commonly used in existing synchronous rectification commutation power supplies has low efficiency and is prone to generating electric arcs during the commutation process, which has a high risk factor. Therefore, we designed a synchronous rectification commutation power supply. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a synchronous rectification and commutation power supply, which can effectively solve the problems of low efficiency and high risk associated with mechanical commutation methods commonly found in existing synchronous rectification and commutation power supplies, as well as the tendency to generate electric arcs during commutation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A synchronous rectifier commutator power supply includes a housing, inside which a battery is fixedly installed, and two electrode plates are connected to the battery respectively.

[0006] The device also includes a lap plate that is fixedly installed inside the housing and located inside the electrode plate, and an adjusting member that is movably connected inside the housing. The adjusting member can move up and down inside the housing. Two frames are fixedly installed on the adjusting member, and a metal plate is movably connected inside the frames.

[0007] It also includes two metal plates laid on the inner wall of the housing, which are electrically connected to the wires fixedly installed on the outer wall of the housing, and two overlapping plates set on the inner wall of the housing, which are electrically connected to the metal plates.

[0008] When the adjusting component is in the uppermost position, the two metal plates in the upper position are electrically connected to the metal sheet and the electrode plate, respectively. When the adjusting component is in the lowermost position, the two metal plates in the lower position are electrically connected to the overlapping piece and the electrode plate, respectively.

[0009] Preferably, a cover is movably connected to the front side of the housing, and a placement slot is provided inside the housing, with the battery installed at the lower side of the placement slot.

[0010] Preferably, the electrode plate is bent, and the outer wall of the overlapping plate overlaps with the inner wall of the electrode plate. A first inclined surface is formed on the outer wall of the overlapping plate, and a through groove is formed through the overlapping plate.

[0011] Preferably, the metal plate is slidably connected to the inside of the frame, and two metal plates in the same frame are elastically connected by a spring. A bending plate is fixedly installed on the outer wall of the metal plate. The bending plate is made of metal. When the adjusting member is in the uppermost position, the outer wall of the bending plate at the outer end of the upper metal plate overlaps with the outer wall of the electrode plate. When the adjusting member is in the lowermost position, the outer wall of the bending plate at the lower side overlaps with the outer wall of the overlapping piece.

[0012] Preferably, a connecting plate is also fixedly connected to the outer wall of the metal plate, and a second inclined surface is provided on the connecting plate, with the first inclined surface and the second inclined surface slidingly engaged.

[0013] Preferably, the lower end of the adjusting component is fixedly installed with a magnetic block, and the component also includes a hydraulic cylinder fixedly installed on the inner wall of the placement slot. The output end of the hydraulic cylinder is fixedly connected to a drive rod, and the upper end of the drive rod is fixedly connected to the magnetic block.

The outer wall of the guide block slides in cooperation with the outer wall of the magnetic block, and two sets of magnetic switches are set on the inner wall of the guide block. When the magnetic switch contacts the magnetic block, the corresponding battery is in the running state.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model, through the setting of adjustment components and metal plates, can achieve simple and quick reversing operation under the drive of hydraulic cylinder. In addition, with the through groove and magnetic switch set on the overlapping plate, the generation of electric arc during the reversing process is avoided by increasing the creepage gap and power-off method, thereby improving the safety of power supply use.

Example

[0033] See attached document Figure 1-5 As shown, the synchronous rectifier commutator power supply includes a housing 100, a battery 300 fixedly installed inside the housing 100, and two electrode plates 310 connected to the battery 300 respectively; a connecting plate 120 fixedly installed inside the housing 100 and located inside the electrode plates 310; an adjusting member 500 movably connected to a position inside the housing 100, the adjusting member 500 being able to move up and down within the housing 100; two frames 510 fixedly installed on the adjusting member 500; and a metal plate 600 movably connected inside the frames 510; and also includes a mounting plate laid on the housing 100. Two metal plates 210 on the inner wall of the housing 100 are electrically connected to the wires 200 on the outer wall of the housing 100, and two overlapping plates 220 on the inner wall of the housing 100 are electrically connected to the metal plates 210. When the adjusting member 500 is in the uppermost position, the two metal plates 600 in the upper position are electrically connected to the metal plates 210 and the electrode plate 310, respectively. When the adjusting member 500 is in the lowermost position, the two metal plates 600 in the lower position are electrically connected to the overlapping plates 220 and the electrode plate 310, respectively. Specifically, in this application, the power connection method within the power supply is as follows: the battery 300 is connected to one of the metal plates 600 through the electrode plate 310. The metal plates 600 at different positions (upper or lower) are electrically connected to the metal sheet 210 or the overlapping piece 220. The corresponding metal sheet 210 and the overlapping piece 220 are electrically connected to the wire 200. It should be noted that in this application, the metal sheet 210 and the overlapping piece 220 serve as commutation structures.

[0034] Reversal process: In this application, a magnetic block 520 is fixedly installed at the lower end of the adjusting member 500, and a hydraulic cylinder 400 is fixedly installed on the inner wall of the placement groove 101. The output end of the hydraulic cylinder 400 is fixedly connected to a drive rod 410, and the upper end of the drive rod 410 is fixedly connected to the magnetic block 520. The metal plate 600 is slidably connected to the inside of the frame 510, and two metal plates 600 in the same frame 510 are elastically connected by a spring 630. A bending plate 610 is fixedly installed on the outer wall of the metal plate 600. The bending plate 610 is made of metal. When the adjusting member 500 is in the uppermost position, the outer wall of the bending plate 610 at the outer end of the upper metal plate 600 overlaps with the outer wall of the electrode plate 310. When the adjusting member 500 is in the lowermost position, the outer wall of the bending plate 610 at the lower end overlaps with the outer wall of the overlapping piece 220.

[0035] The specific reversing process is as follows: First, the hydraulic cylinder 400 drives the adjusting member 500 to adjust its position in the vertical direction. When the adjusting member 500 is in the uppermost position, the outer wall of the connecting plate 620 at the outer end of the two metal plates 600 at the upper position will contact the outer wall of the electrode plate 310, and the bending plate 610 at its inner end will overlap with the outer wall of the metal sheet 210.

[0036] When a reversal is required, the hydraulic cylinder 400 drives the adjusting member 500 to move downward, and the electrode plate 310 is bent. The outer wall of the overlapping plate 120 overlaps with the inner wall of the electrode plate 310. The outer wall of the overlapping plate 120 has a first inclined surface 122. A connecting plate 620 is also fixedly connected to the outer wall of the metal plate 600. The connecting plate 620 has a second inclined surface 621. The first inclined surface 122 and the second inclined surface 621 slide against each other. At this time, the first inclined surface 122 and the second inclined surface 621 slide relative to each other. The two metal plates 600 located on the upper side will move closer to each other, while the two metal plates 600 located on the lower side will move away from each other. Under the action of the spring 630, the outer wall of the connecting plate 620 located at the outer end of the metal plate 600 contacts the outer wall of the electrode plate 310. Correspondingly, the bent plate 610 at the inner end of the metal plate 600 will overlap with the overlapping piece 220, thus completing the reversal.

[0037] It should be noted that, in the vertical direction, the wires 200 connected to the metal piece 210 and the overlapping piece 220 located at the same position are different. That is, the overlapping piece 220 on the left side is electrically connected to the metal piece 210 on the right side, while the overlapping piece 220 on the right side is electrically connected to the metal piece 210 on the left side. This means that when the reversal is completed, the positive and negative terminals of the corresponding wires 200 change.

[0038] In this application, to ensure the safety of power reversal, a cover 110 is movably connected to the front side of the housing 100. A placement slot 101 is provided inside the housing 100, and the battery 300 is installed on the lower side of the placement slot 101. A guide block 130 is also included on the inner wall of the placement slot 101. The outer wall of the guide block 130 slides in conjunction with the outer wall of the magnetic block 520, and two sets of magnetic switches 131 are provided on the inner wall of the guide block 130. When the magnetic switch 131 contacts the magnetic block 520, the corresponding battery 300 is in operation. Specifically, when the drive rod 410 moves the adjusting member 500 to adjust its position in the vertical direction, the magnetic block 520 will slide in the middle of the two guide blocks 130. In conjunction with the magnetic switch 131 set on the outer wall of the guide block 130, the corresponding battery 300 will only enter the operating state when the magnetic block 520 contacts the magnetic switch 131. This means that during the commutation process, the corresponding electrode plate 310 is not energized, thereby ensuring the safety of the commutation.

[0039] Furthermore, in order to prevent the danger caused by electric arcs during the commutation process, a through groove 121 is provided in the lap plate 120 in this application. When the connecting plate 620 slides on the first inclined surface 122, the through groove 121 is provided to increase the creepage gap between the connecting plate 620 and the electrode plate 310, reduce the possibility of electric arc generation, and ensure the safety of the commutation process.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
