Description

Technical Field

[0001] The utility model relates to the technical field of waterproof battery boxes, specifically a battery box with waterproof function. Background Art

[0002] The existing waterproof battery box waterproofing methods include traditional gluing and screw column methods. The traditional gluing method requires a special O-ring removal tool to remove the sealing ring in order to avoid damaging the sealing ring and surrounding components. Specially avoid using sharp or unsuitable tools, which may scratch or damage the sealing ring and its installation groove. The disassembly efficiency is too slow, and excessive force may cause the sealing ring to tear or the surrounding components to deform. Before disassembly, the components near the sealing ring should be cleaned. The existing screw column technology generally exposes the screw column, which is easily damaged, resulting in unnecessary waste of resources. In summary, the existing waterproof battery box is not easy to repair and can meet the effect of quick disassembly. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a battery box with a waterproof function. The gap between the upper and lower plastic shells and the aluminum shell is used. When the upper and lower plastic shells are installed, the sealing ring is clamped in the gap. The gap is generally smaller than the sealing ring, thereby forming interference extrusion on the sealing ring. The size of the gap can be controlled so that the sealing ring can fill the gap to form a sealing effect. At the same time, the screw column is embedded in the upper and lower shells and is not easily damaged.

[0004] To achieve the above-mentioned purpose, a battery box with a waterproof function is designed, including an aluminum shell, an upper shell and a lower shell. The upper shell is provided above the aluminum shell, and an upper sealing ring is provided between the upper shell and the aluminum shell. The upper sealing ring is fixed to the aluminum shell by a screw column. The lower shell is provided below the aluminum shell, and the lower sealing ring is fixed below the aluminum shell by a screw column. The upper sealing ring and the lower sealing ring include a bottom sealing layer, a side sealing layer, a screw column sealing boss, a sealing ring limiting pre-pressure boss, and a fixing groove. The bottom sealing layer is tightly attached to the aluminum shell, and a fixing groove is provided below the bottom sealing layer. A screw column sealing boss is provided on each side of the outer side of the bottom sealing layer. The side sealing layer is connected above the bottom sealing layer, and concave sealing ring limiting pre-pressure bosses are provided on the left and right sides of the side sealing layer.

[0005] The upper sealing ring and the lower sealing ring have the same structure, but are installed in opposite directions.

[0006] The upper shell includes a handle, a step screw, a charging terminal, a silicone button light board, and a PCB light board. The upper shell is rotatably connected to the handle by the step screw. The charging terminal is threadedly connected to the front end of the upper shell. A silicone button light board is embedded inside the upper shell. The PCB light board is connected below the silicone button light board. Screw column slots are provided around the upper shell.

[0007] A protruding stop rib cooperating with the fixing groove is provided below the upper shell, and sealing ring inner extrusion grooves cooperating with the sealing ring limiting pre-pressing bosses are respectively provided on both sides of the lower surface of the upper shell.

[0008] The upper surface of the lower shell is provided with the same protruding stop ribs and sealing ring inner extrusion grooves as those on the lower surface of the upper shell.

[0009] The contact surface between the side sealing layer and the upper shell or the lower shell forms a first sealing surface, the fixing groove contacts the protruding stop rib to form a second sealing surface, and the sealing ring limiting pre-compression boss contacts the sealing ring inner extrusion groove to form a third sealing surface.

[0010] Compared with the prior art, the utility model is provided with a hidden screw column to prevent the screw column from being damaged, and is provided with a special sealing ring at the same time, which tightly fits the upper and lower shells with the aluminum shell to achieve a waterproof effect.

The bottom sealing layer 14 is close to the aluminum shell 1, and a fixing groove 13 is provided below the bottom sealing layer 14. The fixing groove 13 cooperates with the protruding stop rib 18 below the upper shell 2 to achieve the functions of sealing and limiting. Figure 5 As shown, a screw column sealing boss 16 is provided on each side of the bottom sealing layer 14. The upper sealing ring 4 and the lower sealing ring 5 can be fixed to both ends of the aluminum shell 1 by passing the screw column 6 through the sealing boss 16 and the aluminum shell 1. The screw column grooves 23 of the upper shell 2 and the lower shell 3 are set on the corresponding screw columns 6, as shown. Figure 6 As shown, the sealing ring inner extrusion groove 17 on the lower surface of the upper shell 2 is respectively extruded with the sealing ring limiting pre-pressing boss 19 to complete the assembly of the upper shell 2 and the lower shell 3. The side sealing layer 15 is connected above the bottom sealing layer 14. The left and right sides of the side sealing layer 15 are provided with a concave sealing ring limiting pre-pressing boss 19. The contact surface of the side sealing layer 15 and the upper shell 2 or the lower shell 3 forms a first sealing surface 20. The side sealing layer 15 plays a limiting role in the installation of the shell. The fixing groove 13 contacts the protruding stop rib 18 to form a second sealing surface 21. The sealing ring limiting pre-pressing boss 19 contacts the sealing ring inner extrusion groove 17 to form a third sealing surface 22. Figure 7 As shown, the three sealing surfaces work together to achieve a multiple sealing effect, wherein the shapes of the first sealing surface 20, the second sealing surface 21, and the third sealing surface 22 can be replaced, as long as the three contact parts of the side sealing layer 15 and the contact surface between the upper shell 2 or the lower shell 3, the fixing groove 13 and the protruding stop rib 18, and the sealing ring limiting pre-compression boss 19 and the sealing ring inner extrusion groove 17 are mutually sealable concave-convex structures.

[0021] The upper sealing ring 4 and the lower sealing ring 5 have the same structure, but are installed in opposite directions, facing upwards.

[0022] like Figure 2 As shown, the upper shell 2 includes a handle 11, a step screw 10, a charging terminal 9, a silicone button light board 8, and a PCB light board 7.

The silicone button light board 8 is embedded in the upper shell 2. The PCB light board 7 is connected to the bottom of the silicone button light board 8. Screw column grooves 23 are provided around the upper shell 2. The silicone button light board 8 is used to control the switch, and the PCB light board is used to display the remaining power.

[0023] Seal ring inner extrusion grooves 17 are respectively provided on both sides of the lower surface of the upper shell 2 to cooperate with the seal ring limiting pre-compression bosses 19.

[0024] The upper surface of the lower shell 3 is provided with a protruding stop rib 18 and a sealing ring inner extrusion groove 17 which are the same as those of the lower surface of the upper shell 2 .

[0025] The assembly process of the present invention is as follows: prepare an aluminum shell 1 with holes on the upper and lower sides; fix the upper sealing ring 4 and the lower sealing ring 5 to the upper and lower ends of the aluminum shell 1 respectively through screw columns 6; install the terminal 12 for outputting external power in the lower shell 3; install the charging terminal 9 for charging, the handle 11 for auxiliary transportation, the silicone button light board 8 for turning on and off the battery power, and the PCB light board 7 for displaying the remaining battery power in the upper shell 2; take the installation of the upper shell 2 as an example, set the screw column groove 23 of the upper shell 2 on the upper end part of the corresponding screw column 6, the side sealing layer 15 will limit the installation position of the upper shell 2, and the installation accuracy will be improved. Continue to lower the upper shell 2. Install until the sealing ring extrusion groove 17 below the upper shell 2 and the sealing ring limit pre-pressure boss 19 squeeze each other, and the upper shell 2 squeezes and interferes with the upper sealing ring 4 to achieve a sealing effect. The installation process of the lower shell 3 is the same as that of the upper shell 2 and will not be described here. The upper shell 2, the lower shell 3 and the upper sealing ring 4, the lower sealing ring 5 respectively form a first sealing surface 20, a second sealing surface 21, and a third sealing surface 22. The utility model avoids the exposure of the screw column 6 to the outside and embeds the screw column 6 inside the upper and lower plastic shells to achieve three-layer sealing. When subsequent maintenance is required, the removal of the waterproof sealing ring only requires unscrewing the screw column 6. The entire battery box has high installation precision and low cost of use.
