Description

Technical Field

[0001] The utility model relates to the technical field of power supply boards, in particular to a power supply board with a pressure resistance function. Background Art

[0002] The power board is a board that mainly processes power. It is a functional circuit in electronic equipment that converts the input power voltage (such as 220V industrial frequency) into various levels of working voltage (such as 12V, 15V) required by the electronic circuit. When it is made on a circuit board, it is called a power board. The power board is used to provide power to other electronic components or electronic modules, realize voltage conversion functions such as AC to DC conversion, and output the converted voltage to other electronic components or electronic modules.

[0003] An existing patent (authorization announcement number: CN 219042239 U) discloses a power board with a pressure-resistant function, which absorbs the impact pressure from the top of the power board body through the pressure-resistant plate, disperses the pressure on the pressure-resistant plate through the guide rod, and absorbs and buffers the pressure on the pressure-resistant plate through the cooperation of the elastic part and the pressure-resistant plate, thereby realizing the function of providing pressure-resistant protection for the power board body.

[0004] However, the above technical solution still has certain defects. When the anti-pressure plate is subjected to a large external force, it will lower the compression elastic member along the guide rod until it is compressed to the limit, and the middle part of the anti-pressure plate will bend downward until the bent area contacts the power board body. The impact force will still be transmitted to the power board body, thereby causing damage to the power board body. For this reason, a power board with anti-pressure function is proposed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a power board with pressure resistance function to solve the technical problems raised in the above background.

[0015] The utility model absorbs the external force that impacts the power board through the pressure-resistant component, and the longitudinal compression of the spring buffers the force when the force-bearing plate is lowered, and at the same time uses the force of the lowering of the force-bearing plate to make the airbag strip expand and become larger so that it can contact the bottom end of the force-bearing plate, once again achieving the purpose of absorbing the unloading force, avoiding the large impact caused by the force-bearing plate causing the spring to be compressed to the limit, and at the same time allowing space to exist between the lowered force-bearing plate and the power board, preventing the force-bearing plate from bending downward and squeezing the power board, thereby achieving a better protection for the power board.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A power supply board with pressure resistance function, such as Figures 1 to 5As shown, it includes a mounting shell 100, four sets of positioning cylinders 130 are fixed to the inner wall of the bottom end of the mounting shell 100, a power board 120 is installed on the top of the four sets of positioning cylinders 130, four sets of travel grooves 150 are opened on the left and right inner walls of the mounting shell 100 above the power board 120, and a pressure-resistant component 200 is provided in the mounting shell 100 above the power board 120;

[0027] The pressure-resistant assembly 200 includes a force-bearing plate 210 in contact with the left and right inner walls of the mounting shell 100, a restraining rod 240 is fixed in the center of each set of travel grooves 150, a slider 220 is slidably sleeved on the top outer wall of the restraining rod 240, one side of the slider 220 is fixed to the force-bearing plate 210, the bottom end of the slider 220 is located on one side of the restraining rod 240 and a driven bar 221 is fixed, the outer wall of the restraining rod 240 is located below the slider 220 and sleeved with a spring 241, and the left and right inner walls of the mounting shell 100 are located at the driven bar 221. A stroke chamber 140 is opened at the bottom of 21, and two groups of pressurizing cylinders 233 are fixed to the inner wall at the bottom end of the stroke chamber 140. A piston 232 is slidably provided in each group of pressurizing cylinders 233. A pressurizing rod 231 is fixed to the top end of the piston 232. A horizontal bar 230 fixed to the bottom end of the driven bar 221 is transversely provided at the top end of the pressurizing rod 231. The top end of the pressurizing rod 231 is fixedly connected to the bottom end of the horizontal bar 230. Obstruction bars 250 are fixed to the left and right inner walls of the mounting shell 100, and an airbag bar 260 is fixed to the top end of the obstruction bar 250.

[0028] When an external force unexpectedly impacts the force-bearing plate 210, the force-bearing plate 210 causes the sliders 220 connected to the left and right outer walls to be longitudinally lowered along the restraining rod 240, whereupon the spring 241 is compressed and can absorb a certain impact force, and the driven bar 221 connected to the bottom end of the slider 220 moves downward accordingly, and the pressing bar 230 is synchronously lowered, so that the pressurizing rod 231 pushes the piston 232 to slide downward in the pressurizing cylinder 233, so that the air in the pressurizing cylinder 233 is delivered to the airbag bar 260, and the airbag bar 260 expands accordingly and can be aligned with the lowered force-bearing plate 21 0, the force of the force plate 210 being lowered can be absorbed again, and the force plate 210 continues to lower. At this time, the airbag strip 260 continues to expand and is squeezed by the force plate 210 and gradually approaches a flat state, and finally cooperates with the spring 241 to stop the force plate 210 from lowering, thereby achieving the purpose of buffering and unloading the force, and creating a safe distance between the bottom end of the force plate 210 and the power board 120, thereby preventing the bottom of the force plate 210 from disguising itself downward and contacting the power board 120, thereby better protecting the power board 120.

[0029] Please refer to Figure 5 One side of the pressurizing cylinder 233 is connected to a conduit 234 , and a distal end of the conduit 234 extends into the obstruction strip 250 and is connected to the airbag strip 260 .

[0030] The piston 232 compresses the air in the pressurizing cylinder 233 by using the conduit 234 and delivers it to the airbag strip 260 , so that the airbag strip 260 expands and becomes larger to absorb the force when the force-bearing plate 210 is lowered.

[0031] Please refer to Figure 2 and Figure 3 The blocking bar 250 is located above the power board 120 , and one side of the blocking bar 250 is welded and fixed to the inner wall of the mounting shell 100 .

[0032] The blocking bar 250 is fixed to the mounting shell 100 , and can withstand the impact force when the force-bearing plate 210 is lowered, and ensure a safe distance between the force-bearing plate 210 and the power board 120 when the force-bearing plate 210 is lowered to the lowest point.

[0033] Please refer to Figure 1 and Figure 3 The front and rear inner walls of the mounting shell 100 are provided with penetrating fan holes, and a heat dissipation fan 110 is installed in the fan hole.

[0034] The heat generated by the power board 120 when it is working is dissipated to ensure that the power board 120 is working in a relatively suitable environment.

[0035] Please refer to Figure 2 , Figure 3 and Figure 4 The front cross-section of the force-bearing plate 210 is wavy, and there is a certain gap between the front and rear of the force-bearing plate 210 and the inner wall of the mounting shell 100.

[0036] The wavy stress-bearing plate 210 can withstand greater impact force and avoid bending downward to a certain extent. The gaps in the front and rear inner walls of the mounting shell 100 facilitate the entry of outside air and avoid excessive temperature around the power board 120.

[0037] Please refer to Figure 2 and Figure 5 Channels are provided at the positions where the inner walls of both sides of the stroke chamber 140 contact the horizontal bar 230 , and the channels connect the stroke chamber 140 and the stroke groove 150 .

[0038] The opening of the channel utilizes the horizontal bar 230 to slide downward, which can absorb the external impact force, and at the same time make the airbag bar 260 expand to play the effect of buffering and unloading force again.

[0039] Please refer to Figure 2 and Figure 3 A screw penetrating the power board 120 and extending into the positioning tube 130 is disposed at the top of the positioning tube 130 , and a screw hole matching the bolt is opened at the top of the positioning tube 130 .

[0040] The power board 120 is positioned using screws to ensure that it works in a stable state.

[0041] During use, when an external force unexpectedly impacts the force-bearing plate 210, the force-bearing plate 210 causes the sliders 220 connected to the left and right outer walls to be longitudinally lowered along the restraining rod 240, whereupon the spring 241 is compressed and can absorb a certain impact force, and the driven bar 221 connected to the bottom end of the slider 220 moves downward accordingly, and the pressing bar 230 is synchronously lowered, so that the pressurizing rod 231 pushes the piston 232 to slide downward in the pressurizing cylinder 233, so that the air in the pressurizing cylinder 233 is delivered to the airbag bar 260, and the airbag bar 260 expands accordingly and can contact the bottom end of the lowered force-bearing plate 210, which can pressurize the force-bearing plate 210 0 The force of reduction is absorbed again, and the force-bearing plate 210 continues to be reduced. At this time, the airbag strip 260 continues to expand and is squeezed by the force-bearing plate 210 and gradually approaches a flat state, and finally cooperates with the spring 241 to stop the force-bearing plate 210 from being reduced, thereby achieving the purpose of buffering and unloading the force, and creating a safe distance between the bottom end of the force-bearing plate 210 and the power board 120, thereby preventing the bottom of the force-bearing plate 210 from being transformed downward and contacting the power board 120, thereby better protecting the power board 120. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
