Description

Technical Field

[0001] The utility model relates to the technical field of mobile power supply boards, and specifically relates to a mobile power supply board for combined use. Background Technique

[0002] A power supply board is a motherboard mainly for power processing, and the power processing methods are diversified according to the requirements of subsequent circuits. For example, input / output types: AC, DC, pulse, high voltage, low voltage, high frequency, low frequency, single path, multi-path; conversion types: boost, buck, constant voltage, constant current, linear, non-linear controllable; circuit methods: coil-coupled transformer, electronic device type switching power supply.

[0003] However, when the existing mobile power supply board is in use, when it is connected to the main board, due to the offset of the mounting position holes of the main board, the mobile power supply board cannot be assembled. Moreover, the connection method between the power supply boards is to connect with screws and connectors, and this method requires tools for connection, which is relatively cumbersome and not convenient for employees to operate.

[0004] The Chinese Patent Network discloses a mobile power supply board CN213847139U. This utility model connects through a connecting spring and a clamping block, and a fixing screw is connected to the power supply board by a compression spring, so that the power supply boards are firmly combined, the offset is reduced, and the assembly difficulty is lowered. However, due to mostly mechanical fixation, mechanical biting deviation is likely to occur in the case of long-term use or improper operation. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mobile power supply board for combined use, which has the characteristics of electromagnetic fitting and simple operation, so as to solve the problems put forward in the above background technique.

[0006] In order to solve the above technical problems, the utility model provides the following technical solution: A mobile power supply board for combined use, including a power supply board and a fixing structure. The power supply board is two PCB circuit boards spliced together, and the fixing structure is installed at the middle edge of the power supply board and connects the two power supply boards.

[0007] During use, after the fixing structures on the upper and lower surfaces of the two power supply boards are combined and spliced with each other, then the positive and negative interfaces on the splicing magnet are used to make the electromagnet obtain magnetism and fit with each other. After the gaps between the power supply boards are completely spliced, the toothed limiting strips on the fixing slots are locked, and the compression spring is locked to complete the combination of the power supply boards.

[0008] Preferably, the power supply board includes a substrate, a splicing magnet and a foot pad. The substrate is the main structure of the power supply board, the splicing magnet is an electromagnetic strip installed on one side edge of the substrate, and the foot pad is two silicone triangular pad structures arranged on the other side edge of the substrate.

[0009] Preferably, the splicing magnet is provided with a positive interface and a negative interface, which are located on the side walls on both sides of the splicing magnet, and the positive interfaces and negative interfaces on both side walls are arranged in a vertical and parallel form.

[0010] Placing the power interfaces at two locations vertically offset can avoid the situation of like-pole repulsion when the two power boards are attached and energized.

[0011] Preferably, the fixing structure includes a fixing pin and a fixing slot. The fixing pin and the fixing slot are respectively located on the upper and lower surfaces of the power board, and the fixing pin is connected to the fixing slot when the power boards are combined.

[0012] By respectively arranging the fixing pin and the fixing slot on the upper and lower sides, connection and fixation can be carried out on both the upper and lower surfaces of the power board simultaneously, which can not only improve the connection stability but also reduce the production difficulty.

[0013] Preferably, the fixing pin includes a fixing block, a compression spring, and a pin. The fixing block is fixed on the substrate, the compression spring is connected to the fixing block, and the pin is a two-claw snap structure.

[0014] The compression spring serves as the connection force output device between the fixing pin and the fixing slot, pressing the joint of the two structures tightly to avoid loosening and movement.

[0015] Preferably, the fixing slot includes a slot, a toothed limit strip, and a rotating seat. The slot matches the fixing pin, the toothed limit strip is a telescopic strip with sawteeth on both sides, and the rotating seat is fixed on the substrate and connected to the toothed limit strip.

[0016] The toothed limit strip can control the extension length of the fixing slot, thereby controlling the length of the compression spring, limiting the overall length of the fixing structure, and avoiding the position of the pin and the slot from shifting, which may lead to instability at the joint.

[0017] Compared with the prior art, the present utility model provides a combined mobile power board, which has the following beneficial effects: The combined mobile power board uses the characteristic of mutual attraction of electromagnets as the connection method of the power pieces. This method can automatically fit during the energized use of the power board. With the fixing structure of the installed power board, the combination process and difficulty are further simplified, and the assembly pass rate of the device is improved.

The power supply board 1 is two PCB circuit boards spliced together. The fixing structure 2 is installed at the middle edge of the power supply board 1 and connects the two power supply boards 1.

[0024] When in use, after the fixing structures 2 on the upper and lower surfaces of the two power supply boards 1 are combined and spliced with each other, the electromagnet obtains magnetism through the positive interface 1021 and the negative interface 1022 on the splicing magnet 102, and fits together. After the gap between the power supply boards 1 is completely spliced, the tooth-shaped limiting strip 2022 on the fixing slot 202 is locked, and the compression spring 2012 is locked to complete the combination of the power supply boards 1.

[0025] Specifically, the power supply board 1 includes a substrate 101, a splicing magnet 102 and a foot pad 103. The substrate 101 is the main structure of the power supply board 1. The splicing magnet 102 is an electromagnetic strip installed on one side edge of the substrate 101. The foot pad 103 is two silica gel triangular pad structures arranged on the other side edge of the substrate 101.

[0026] Specifically, the splicing magnet 102 is provided with a positive interface 1021 and a negative interface 1022 on both side walls. The positive interfaces 1021 and the negative interfaces 1022 on both side walls are arranged in a vertical and parallel form.

[0027] Through the above technical solution, the power interfaces at the two places are arranged with vertical displacement, which can avoid the situation of like-pole repulsion when the two power supply boards 1 are attached and powered on.

[0028] Specifically, the fixing structure 2 includes a fixing pin 201 and a fixing slot 202. The fixing pin 201 and the fixing slot 202 are respectively located on the upper and lower surfaces of the power supply board 1. When the power supply board 1 is combined, the fixing pin 201 is connected to the fixing slot 202.

[0029] Through the above technical solution, by respectively arranging the fixing pin 201 and the fixing slot 202 on the upper and lower sides, connection and fixation can be carried out simultaneously on the upper and lower surfaces of the power supply board 1, which can not only improve the connection stability but also reduce the production difficulty.

[0030] Specifically, the fixing pin 201 includes a fixing block 2011, a compression spring 2012 and a pin 2013. The fixing block 2011 is fixed on the substrate 101, the compression spring 2012 is connected to the fixing block 2011, and the pin 2013 is a two-claw buckle structure.

[0031] Through the above technical solution, the compression spring 2012 serves as a connecting force output device for the fixing pin 201 and the fixing slot 202, pressing the joint of the two structures tightly to avoid loosening and displacement.

[0032] Specifically, the fixing slot 202 includes a slot 2021, a toothed limiting strip 2022 and a rotating seat 2023. The slot 2021 matches the fixing pin 201. The toothed limiting strip 2022 is a telescopic strip with sawteeth on both sides. The rotating seat 2023 is fixed on the substrate 101 and is connected to the toothed limiting strip 2022.

[0033] Through the above technical solution, the toothed limiting strip 2022 can control the extension length of the fixing slot 202, thereby controlling the length of the compression spring 2012, limiting the overall length of the fixing structure 2, and preventing the positions of the pin 2013 and the slot 2021 from shifting, which may otherwise cause instability at the joint.
