Description

Technical Field

[0001] The utility model relates to the technical field of battery protection plates, in particular to a battery protection plate with a sealed and waterproof structure. Background Art

[0002] As the name suggests, a battery protection board is an integrated circuit board that primarily protects rechargeable batteries (generally referring to lithium batteries). The need for protection for rechargeable lithium batteries stems from their inherent characteristics. Because the materials used in lithium batteries prevent them from being overcharged, over-discharged, overcurrented, short-circuited, or subjected to ultra-high-temperature charging and discharging, lithium battery components are always accompanied by a protection board with a sampling resistor and a current fuse. The battery protection board lacks specialized waterproofing, resulting in poor waterproofing. Moisture can penetrate the battery or the battery protection board through gaps. Existing power protection boards are all exposed, causing damage to internal components and affecting the power supply's performance. Once the protection board becomes damp or waterlogged, it can easily lose its protective function for the lithium battery. Therefore, we have proposed a battery protection board with a sealed, waterproof structure to address these issues. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The present invention provides an embodiment of a battery protection board with a sealed and waterproof structure, comprising a battery board 1,

[0022] A fixing frame 2 is fixedly installed on the upper end of the solar panel 1, and a protective shell 3 is fixedly installed on the fixing frame 2. Bumps 6 are fixedly installed on the upper sides of the left and right ends of the fixing frame 2. Grooves 7 are provided on the left and right ends of the protective shell 3. Two groups of bumps 6 are movably inserted into the two groups of grooves 7. Locking components are provided in the two groups of bumps 6 and the left and right ends of the protective shell 3. This device aligns and fits the protective shell 3 with the fixing frame 2, and uses the locking component to fix the protective shell 3 and the fixing frame 2 together, and the solar panel 1 is waterproof and sealed through the protective shell 3.

[0023] Furthermore, the front cross-section of the fixed frame 2 is trapezoidal, the length and width of the upper outer wall of the fixed frame 2 are greater than the length and width of the lower outer wall of the fixed frame, and the upper outer wall of the fixed frame 2 is tightly fitted with the lower inner wall of the protective shell 3. This structure is based on the front cross-section shape of the fixed frame 2, so that the upper end of the fixed frame 2 is fitted with the inner wall of the protective shell 3, thereby improving the sealing after the protective shell 3 is connected to the fixed frame 2, and preventing water from entering the protective shell 3.

[0024] Furthermore, a mesh plate 4 is installed on the inner wall of the upper end of the protective shell 3, and a desiccant 5 is provided in the interlayer between the upper side of the mesh plate 4 and the inner wall of the upper side of the protective shell 3. This structure dries the gas when it enters the protective shell 3 through the mesh plate 4 and the desiccant 5, thereby preventing moisture contained in the air from contaminating the components on the surface of the solar panel 1.

[0025] Furthermore, the mesh plate 4 is hollow as a whole, and the desiccant 5 is composed of activated carbon. According to the shape of the mesh plate 4, the desiccant 5 can fully contact the gas entering the protective shell 3 through the mesh plate 4, thereby drying the moisture in the gas.

[0026] Furthermore, the locking assembly includes eight groups of slide grooves 8, which are respectively opened at the left and right ends of the protective shell 3 and in the two groups of protrusions 6. The eight groups of slide grooves 8 on the left and right ends of the protective shell 3 and the two groups of protrusions 6 are symmetrically arranged front to back. Slide blocks 9 are slidably installed in the four groups of slide grooves 8 on the two groups of protrusions 6. Movable grooves 10 are opened in the two groups of slide blocks 9. Springs 11 are installed in the four groups of movable grooves 10. Limit blocks 12 are installed at the openings of the four groups of movable grooves 10. Two groups of limiting grooves 13 are opened on the inner walls of the four groups of slide grooves 8 on the two groups of protrusions 6. Handles 14 are fixedly installed on the four groups of slide blocks 9. When the protective shell 3 is installed on the fixed frame 2 with this structure, the four groups of slide blocks 9 are inserted into the four groups of slide grooves 8 on the protective shell 3, and the four groups of slide blocks 9 are slid in the eight groups of slide grooves 8, and the four groups of limiting blocks 12 are inserted into the four groups of limiting grooves 13, the protective shell 3 can be limited and fixed on the fixed frame 2, which is convenient for installation and disassembly of the protective shell 3.

[0027] Furthermore, the end of the limit block 12 outside the movable groove 10 and the inner wall of the limit groove 13 are both hemispherical, and the end of the limit block 12 outside the movable groove 10 is adapted to the inner wall of the limit groove 13. This structure is based on the shape of the end of the limit block 12 outside the movable groove 10 and the inner wall of the limit groove 13, so that the limit block 12 can slide out of the limit groove 13 when squeezed, thereby facilitating the movement of the slider 9 in the slide groove 8.

[0028] Furthermore, the four groups of slide grooves 8 at the left and right ends of the protective shell 3 are all inverted L-shaped, and the diameter of one end of the four groups of sliders 9 that fits against the outer wall of the protective shell 3 is larger than the upper and lower widths of the slide groove 8 opening. This structure is based on the shape of the four groups of slide grooves 8 at the left and right ends of the protective shell 3, so that when the protective shell 3 is installed on the fixed frame 2, the running trajectory of the four groups of sliders 9 in the four groups of slide grooves 8 on the protective shell 3 is consistent with the shape of the four groups of slide grooves 8, so that the protective shell 3 can be limited and fixed.

[0029] Furthermore, the sides where the lower ends of the fixing frame 2 and the protective shell 3 are in contact are wrapped with rubber sealing pads. This structure improves the sealing performance of the connection between the fixing frame 2 and the protective shell 3 through the rubber sealing pads at the connection between the fixing frame 2 and the protective shell 3.

[0030] Working principle: When the protective shell 3 is installed on the fixed frame 2, Figure 3 and Figure 4As shown, first align the protective shell 3 with the fixed frame 2, and clamp the protective shell 3 on the fixed frame 2, and the four groups of sliders 9 on the two groups of protrusions 6 enter the four groups of slide grooves 8 at the left and right ends of the protective shell 3. After the protective shell 3 is completely fitted with the fixed frame 2, pull the four groups of sliders 9. When the four groups of sliders 9 slide in the eight groups of slide grooves 8, the limit blocks 12 inserted in the four groups of limit grooves 13 are squeezed and slide into the four groups of movable grooves 10. After the four groups of sliders 9 are moved, the limit blocks 12 in the four groups of movable grooves 10 pop out under the action of the restoring force of the spring 11. After the four groups of limit blocks 12 pop out, they are inserted into the four groups of limit grooves 13, and the protective shell 3 can be fixedly installed on the fixed frame 2. The above is the entire working principle of the present utility model.
