[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1-3 As shown, the present invention provides a lithium battery system with an LED light panel, including a housing 100, a battery module 200, a BMS assembly 300, and a display control component 400. The housing 100 has a switch hole 10a and a light hole 10b. The battery module 200 is installed inside the housing 100. The BMS assembly 300 is installed inside the housing 100 and connected to the battery module 200. The display control component 400 has a mounting surface that is sealed against the inner wall of the housing 100. The mounting surface of the display control component 400 is provided with a control terminal and a display terminal that are electrically connected to the BMS assembly 300. The control terminal passes through the switch hole 10a and extends to the outside of the housing 100, and the display terminal is positioned facing the light hole 10b.

[0022] In implementation, the mounting surface of the display control component 400 is sealed against the inner wall of the housing 100. At the same time, the control terminal passes through the switch hole 10a and extends to the outside of the housing 100, and the display terminal is positioned facing the lamp hole 10b. Since the control terminal and the display terminal are electrically connected to the BMS assembly 300, and the BMS assembly 300 is connected to the battery module 200, the control terminal can control the opening and closing of the battery module 200, and the display terminal can display the status of the battery module 200. The aforementioned display control component 400 is mounted on the inner wall of the housing 100, eliminating the need for an additional housing protection structure, resulting in a high degree of integration and low production cost.

[0023] The housing 100 in this embodiment includes a box body 110, a box cover 120 and a sealing gasket 130130. The top of the box body 110 is open and detachably connected to the box cover 120. The sealing gasket 130130 is disposed between the box body 110 and the box cover 120. A switch hole 10a and a lamp hole 10b are formed on the box cover 120.

[0024] Among them, the sealing gasket 130130 can prevent the leakage of gas, liquid or solid particles, thereby ensuring the sealing level of the lithium battery system.

[0025] The top of the lid 120 is equipped with two handles 121 for easy disassembly and assembly. The handles 121 can be rotatably connected to the lid 120 via connecting blocks 122. When in use, the handles 121 can be rotated to a position perpendicular to the lid 120. In other cases, the handles 121 can be rotated to a position close to the lid 120 to save space.

[0026] In this embodiment, the outer wall of the housing 110 is equipped with a positive terminal 111, a negative terminal 112, and a waterproof and ventilated valve 113 that communicate with its interior. The positive terminal 111 and the negative terminal 112 can be connected to the positive and negative terminals of the battery module 200, respectively. The waterproof and ventilated valve 113 should have waterproof and ventilated functions to ensure pressure balance within the lithium battery system. When the internal pressure of the lithium battery system reaches a certain level, the valve should have a pressure relief function to prevent the housing 110 and the cover 120 from rupturing due to increased pressure.

[0027] The battery module 200 in this embodiment includes multiple battery cells. The battery cells are bonded together with double-sided adhesive buffer foam. Then, epoxy boards are used to reinforce both ends of the battery cell assembly. Fiberglass tape is wrapped around the upper and lower parts of the battery module 200 to pack them into a group.

[0028] like Figure 1 and Figure 4As shown, in this embodiment, there are two battery modules 200. To facilitate defining the position of the battery modules 200 in the housing 110, the lithium battery system includes three positioning ribs 230 disposed on the bottom wall of the housing 110. The three positioning ribs 230 are arranged in parallel and form two mounting cavities between them. The bottoms of the two battery modules 200 are respectively embedded in the two mounting cavities. At the same time, the lithium battery system also includes a first pressure strip 210 and a second pressure strip 220. The bottom of the battery module 200 is fixedly connected to the outer shell 100 via the first pressure strip 210, and the top of the battery module 200 is fixedly connected to the outer shell 100 via the second pressure strip 220. The three positioning ribs 230 can limit the position of the two battery modules 200 along the first horizontal direction, and the first pressure strip 210 can limit the position of the two battery modules 200 along the second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to each other. The second pressure strip 220 can limit the position of the battery module 200 along the vertical direction, thereby ensuring that the battery module 200 does not shift during vibration.

[0029] The positioning rib 230, the first pressure strip 210 and the second pressure strip 220 can all adopt a long strip-shaped plate structure. The positioning rib 230 and the first pressure strip 210 are arranged perpendicular to each other. The first pressure strip 210 can be fixed on the positioning rib 230. One end of the second pressure strip 220 is fixedly connected to the top of the battery module 200, and the other end of the second pressure strip 220 is fixedly connected to the inner wall of the housing 110.

[0030] Of course, in other embodiments, the number of battery modules 200 can be set to multiple, and other forms of limiting structures can also be used to achieve the connection between the battery module 200 and the housing 100.

[0031] In this implementation scheme, the BMS assembly 300 is a battery management system, which is connected to the battery module 200 and is used to control the switching on and off of the battery module 200 and detect the working status of the battery module 200.

[0032] The BMS assembly 300 is mounted on the first pressure strip 210 with screws to control the battery module 200. It connects to electrical components and forms a path with the positive terminal 111 and negative terminal 112 of the lower housing 110. The BMS assembly 300 transmits signals to the LED light board 410 through a wiring harness to realize operations such as power display and power on / off.

[0033] In this embodiment, the display control component 400 is electrically connected to the BMS assembly 300. The display control component 400 can control the battery module 200 and turn it on and off, while also displaying the operating status of the battery module 200. Specifically, the display control component 400 has a mounting surface that is sealed against the inner wall of the housing 100. The mounting surface of the display control component 400 is provided with a control terminal and a display terminal that are electrically connected to the BMS assembly 300. The control terminal passes through the switch hole 10a and extends to the outside of the housing 100, while the display terminal is positioned directly opposite the lamp hole 10b.

[0034] The display control component 400 in this embodiment includes an LED light panel 410, a lampshade 420, a button 430, and a sealing ring 440. The LED light panel 410 and the lampshade 420 are detachably connected. The LED light panel 410 and / or the lampshade 420 are fixedly connected to the inner wall of the housing 100. An annular sealing groove 42c is formed on the side of the lampshade 420 away from the LED light panel 410. The sealing ring 440 is embedded in the sealing groove 42c and seals against the inner wall of the housing 100. A cavity is formed inside the sealing ring 440 that connects the switch hole 10a and the lamp hole 10b. A first mounting hole 42a and a second mounting hole 42b are formed on the part of the lampshade 420 facing the cavity. The button 430 is disposed in the first mounting hole 42a and abuts against the control terminal on the LED light panel 410. The display terminal on the LED light panel 410 is disposed facing the second mounting hole 42b.

[0035] The control terminal on the LED light panel 410 is a switch contact 411 connected to the BMS assembly 300. By moving the button 430 toward the switch contact 411, the switch contact 411 can be triggered, thereby turning the battery module 200 on or off.

[0036] The button 430 is made of silicone / rubber material, which ensures sealing performance during compression while also ensuring a certain strength of the material, and can effectively activate the switch contact 411 on the LED light board 410 during the pressing process.

[0037] To improve the sealing performance at button 430, in one embodiment, the display control assembly further includes a base plate 431. Button 430 has an elastic structure, and the side of button 430 near the LED light panel 410 is fixedly connected to the base plate 431. A U-shaped groove 43a is formed on the side of the base plate 431 near the lampshade 420, and a U-shaped lip is formed on the part of the lampshade 420 near the base plate. The U-shaped lip is fitted into the U-shaped groove 43a. Through the cooperation between the U-shaped lip and the U-shaped groove 43a, the sealing level between the lampshade and the outside environment can be guaranteed to reach IP67 after the lampshade is installed. To enhance the sealing level, a secondary sealing protection can be provided using sealant in the U-shaped groove 43a. The sealant can also be other materials such as hot melt adhesive, UV-cured adhesive, or pre-formed sealing film. Meanwhile, the U-shaped groove 43a can be replaced with other types such as L-shaped grooves or V-shaped grooves.

[0038] In a further embodiment, the top of the base plate 431 is fixedly connected to a plurality of limiting posts 432 evenly arranged around the button 430, and the plurality of limiting posts 432 are respectively engaged and connected with a plurality of limiting slots 42d opened at the U-shaped edge of the lampshade 420.

[0039] The sealing ring 440, located between the lampshade 420 and the housing 100, provides a seal between the mounting surface of the display control component 400 and the inner wall of the housing 100. In this embodiment, the sealing ring 440 is an O-ring; however, in other preferred embodiments, it can be replaced with a silicone gasket or other sealing structure.

[0040] To display the battery's operating status, in one embodiment, the display terminal on the LED light panel 410 consists of multiple LED beads 412 connected to the BMS assembly 300, and the first mounting hole 42a has multiple holes, each corresponding to one of the LED beads 412. Information such as battery level and temperature can be expressed by controlling the number of lights or the color of the lights.

[0041] After the LED light board 410 and the lamp cover 420 are assembled, high-transparency electronic potting compound can be added to the second mounting hole 42b of the lamp cover 420 to seal the LED bead 412 and achieve the IP67 requirement.

[0042] In one embodiment, the plurality of LED beads 412 have a cuboid structure, and the shape and size of the second mounting hole 42b are adapted to the shape and size of the LED beads 412. This configuration allows for the limiting of the LED beads 412. Of course, the LED beads 412 can also be implemented using other shapes such as circles; this is not a limitation.

[0043] To facilitate the detachable connection between the LED light panel 410 and the lampshade 420, in one embodiment, at least one clip 421 is installed on both sides of the lampshade 420 along its length direction. A snap-fit ​​gap for fixing the LED light panel 410 is formed between the multiple clips 421. The number and / or position of the clips 421 on both sides are not equal, which can be used for product foolproof design.

[0044] Compared with the prior art: The mounting surface of the display control component 400 is sealed and abuts against the inner wall of the housing 100. At the same time, the control terminal passes through the switch hole 10a and extends to the outside of the housing 100, and the display terminal is set facing the lamp hole 10b. Since the control terminal and the display terminal are electrically connected to the BMS assembly 300, and the BMS assembly 300 is connected to the battery module 200, the control terminal can control the opening and closing of the battery module 200, and the display terminal can display the status of the battery module 200. The above-mentioned display control component 400 is mounted on the inner wall of the housing 100, without the need for an additional housing protection structure, resulting in a high degree of integration and low production cost.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
