Description

Technical Field

[0001] The utility model relates to the technical field of power boards, in particular to a high-sealing power board component. Background Art

[0002] A power source is a device that converts other forms of energy into electrical energy. The power source is based on the principle of "magnetoelectricity" and is generated by renewable energy sources such as hydropower, wind power, sea tides, water pressure differences in dams, solar energy, and burning coal, oil residue, etc. Common power sources are dry batteries (DC) and household 110V-220V AC power sources.

[0003] An existing patent (authorization announcement number: CN 220511484 U) discloses a highly sealed power board assembly, which places the power board inside a power protection board and expands by pushing a clamping block outward. The second spring performs elastic back pressure, and the clamping block and the slide groove slide together to achieve greater movement stability. The top of the clamping block is clamped and fixed by resistance, and is clamped by the four corner edges to ensure greater firmness, prevent detachment, and facilitate installation and disassembly.

[0004] However, the above technical solution still has certain defects. During disassembly and assembly, it is necessary to manually pull the latch plate to release the lock on the top plate, and at the same time move the clamping block to the side away from the power board before the power board can be removed. This results in more disassembly and assembly steps for the power board, which in turn leads to low disassembly and assembly efficiency of the power board. For this reason, a highly sealed power board assembly is proposed. Utility Model Content

[0026] 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.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0029] The sealing cover assembly 200 includes a substrate 230 in contact with the outer frame 100, a sealing frame 240 is fixed to the bottom end of the substrate 230, the bottom end of the sealing frame 240 extends into the docking groove 120, two sets of positioning plates 210 are slidably provided at the top end of the substrate 230, a constraint plate 220 is fixed to one end of the positioning plate 210 close to the constraint frame 130, and the constraint plate 220 extends into the constraint frame 130.

[0030] The power board is placed in the outer frame 100 and between the four groups of L arms 140, and the circuit between the external components is connected. Finally, the sealing cover assembly 200 is placed on the upper surface of the outer frame 100, and an external force is applied to make it downward, so that the sealing frame 240 is completely inserted into the docking groove 120, and the trapezoidal frame bar 160 extends into the groove opened at the bottom end of the sealing frame 240. The two are tightly fitted to achieve the purpose of sealing. At this time, the trapezoidal frame bar 160 is squeezed and lowered by the sealing frame 240, and then the second piston 162 is pushed down by the active rod 161 to compress the air in the L-shaped cylinder cavity 170, and then the first piston 142 moves laterally to ensure that the pressure in the L-shaped cylinder cavity 170 is normal. At the same time, under the action of the driven rod 141, the L arm 140 is pushed close to the power board to achieve a restraining effect, so as to achieve sealing and lock the power board at the same time, thereby facilitating subsequent maintenance and replacement processes, thereby improving subsequent maintenance efficiency in disguise.

[0031] Please refer to Figure 1 and Figure 2 A positioning frame 110 is fixed to the outer walls of the outer frame 100 , and the positioning frame 110 is located at a position of the outer wall of the outer frame 100 close to the lower surface.

[0032] The outer frame 100 can be conveniently fixed at a desired position to ensure that the power board can work stably.

[0033] Please refer to Figure 1The front and rear surfaces of the outer frame 100 are provided with fan holes, a fan is installed in the fan hole, and a filter is fixed at a position of the fan hole near the outer wall of the outer frame 100.

[0034] The heat generated by the power board can be evacuated and a certain protective effect can be achieved, further extending its service life.

[0035] Please refer to Figure 1 A groove matching the trapezoidal frame bar 160 is formed at the bottom of the sealing frame 240 , and a rubber pad is pasted on the outer wall of the trapezoidal frame bar 160 .

[0036] The gap between the two is filled with a rubber pad to ensure that the butt joint groove 120 is in a sealed state when the sealing frame 240 is inserted into the butt joint groove 120 .

[0037] Please refer to Figure 6 and Figure 7 The outer wall of the active rod 161 is located in the L-shaped cylindrical cavity 170 and is sleeved with a first spring. The outer wall of the driven rod 141 is located in the L-shaped cylindrical cavity 170 and is sleeved with a second spring. A channel is opened at the contact position between the outer frame 100 and the driven rod 141 and the active rod 161, and the channel is connected to the L-shaped cylindrical cavity 170.

[0038] The active rod 161 and the driven rod 141 are automatically restored by the spring after they move, so that when the sealing cover assembly 200 is manually removed, the power board is restrained and the power board can be directly removed from the outer frame 100 for maintenance or replacement.

[0039] Please refer to Figure 5 Slide blocks extending into the restraining groove 150 are provided on both sides of the L-arm 140, and slide block grooves are provided at the positions where the left and right inner walls of the restraining groove 150 contact the slide blocks.

[0040] The slider and the slider slot cooperate to ensure that the L arm 140 moves in a horizontal state in the restraining slot 150 until the power board is restrained.

[0041] Please refer to 3 and Figure 4 The top of the base plate 230 is provided with two sets of dovetail blocks 231 extending into the lower surface of the positioning plate 210 , and a dovetail groove 211 is provided at the contact position between the bottom end of the positioning plate 210 and the dovetail blocks 231 .

[0042] The dovetail block 231 and the dovetail groove 211 are used to constrain the positioning plate 210 so that it can only slide horizontally on the upper surface of the base plate 230, while increasing the friction between the two to ensure that the positioning plate 210 will not move arbitrarily after movement.

[0043] When in use, the power board is placed in the outer frame 100 and between the four groups of L arms 140, and the circuit between the external components is connected. Finally, the sealing cover assembly 200 is placed on the upper surface of the outer frame 100, and an external force is applied to make it downward, so that the sealing frame 240 is completely inserted into the docking groove 120, and the trapezoidal frame bar 160 extends into the groove opened at the bottom end of the sealing frame 240. The two are tightly fitted to achieve the purpose of sealing. At this time, the trapezoidal frame bar 160 is squeezed and lowered by the sealing frame 240, and then the second piston 162 is pushed down by the active rod 161 to compress the air in the L-shaped cylinder cavity 170, and then the first piston 142 moves laterally to ensure that the pressure in the L-shaped cylinder cavity 170 is normal. At the same time, under the action of the driven rod 141, the L arm 140 is pushed close to the power board to achieve a restraining effect, and the power board is locked while achieving sealing, thereby facilitating subsequent maintenance and replacement processes, and improving subsequent maintenance efficiency in disguise. 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.
