Description

Technical Field

[0001] This application relates to the field of battery casing technology, and in particular to a solar cell casing. Background Technology

[0002] In portable devices and outdoor power supplies, these products include battery casings to house the batteries. As the core power supply component, the battery's casing structure affects the device's portability, assembly efficiency, and ease of maintenance.

[0003] Batteries typically require bolts or clips to secure the battery casing, which serves both installation and protection purposes. Inside the battery casing is a cavity containing a circuit board assembly that works in conjunction with the battery. When the circuit board assembly needs repair, the battery casing must be removed first, followed by the removal of the circuit board assembly.

[0004] Regarding the aforementioned technologies, traditional battery casings are mostly one-piece or single-opening. One-piece casings impose significant limitations on battery installation and circuit board assembly maintenance. Due to unreasonable structural design, damage to the battery or circuit board assembly often occurs during disassembly and assembly, failing to adequately guarantee the product's integrity and thus requiring improvement. Utility Model Content

[0005] To facilitate the disassembly, assembly, and maintenance of components within the housing and to reduce damage to these components, this application provides a solar cell housing.

[0006] The solar cell housing provided in this application adopts the following technical solution: A solar cell housing includes an upper cover, a connecting shell, and a lower cover. The connecting shell is hollow and forms a receiving cavity for mounting the battery and circuit board assembly. The connecting shell includes an upper outer frame, a rectangular frame, and a lower outer frame that are connected to each other. The rectangular frame connects the upper and lower outer frames. The upper outer frame has an opening, and the upper cover is detachably connected to the upper outer frame. The lower outer frame also has an opening, and the lower cover is detachably connected to the lower outer frame.

[0007] By adopting the above technical solution, the cavity formed by the connecting shell can accommodate the installation of the battery and circuit board assembly. After the battery and circuit board assembly are installed, the staff will install the upper cover and lower cover on the connecting shell in sequence to achieve isolation and protection for each component.

[0008] When components require maintenance, workers can remove the upper cover plate from the upper outer frame and the lower cover plate from the lower outer frame simultaneously, opening the two sides of the connecting shell and providing sufficient operating space. This modular design of the upper cover plate, lower cover plate, and connecting shell minimizes damage to components during disassembly and assembly.

[0009] Preferably, the upper outer frame has a first slot, and the upper cover plate is snapped into the first slot; an upper connecting block is connected to the upper cover plate, the upper connecting block has a threaded hole, the upper outer frame has a corresponding upper through hole, and a bolt passes through the upper through hole and is screwed to the upper connecting block; wherein, a plurality of upper connecting blocks are spaced apart.

[0010] By adopting the above technical solution, the upper cover plate is snapped into the first slot, relying on friction to pre-fix the upper cover plate. Then, the workers use bolts to pass through the upper through holes of the upper outer frame and screw them onto the upper connecting blocks, relying on the bolt force to further fix the upper cover plate and prevent it from falling off. Among them, multiple upper connecting blocks correspond to multiple bolts, and the upper cover plate is locked together by multiple bolts, which improves the stability of the connection between the upper cover plate and the upper outer frame.

[0011] Preferably, the lower outer frame has a second slot, and the lower cover plate is snapped into the second slot; a lower connecting block is connected to the lower cover plate, the lower connecting block has a threaded hole, the lower outer frame has a corresponding lower through hole, and a bolt passes through the lower through hole and is screwed to the lower connecting block; wherein, a plurality of lower connecting blocks are spaced apart.

[0012] By adopting the above technical solution, the lower cover plate is snapped into the second slot, relying on friction to pre-fix the lower cover plate. Then, the workers use bolts to pass through the lower through holes of the lower outer frame and screw them into the lower connecting blocks, relying on the bolt force to further fix the lower cover plate and prevent the upper cover plate from falling off. Among them, multiple lower connecting blocks correspond to multiple bolts, and the lower cover plate is locked together by multiple bolts, which improves the stability of the connection between the lower cover plate and the lower outer frame.

[0013] Preferably, both the upper cover plate and the lower cover plate have raised textures on their surfaces.

[0014] By adopting the above technical solution, when workers pick up or transfer the entire product, their hands need to come into contact with the battery casing. The presence of the raised texture can increase the roughness of the surfaces of the upper and lower cover plates, thereby increasing the static friction between the workers' hands and the battery casing and improving stability.

[0015] Preferably, a partition plate is connected to the rectangular frame, the partition plate is disposed in the receiving cavity, and divides the rectangular frame into two compartments.

[0016] By adopting the above technical solution, the partition plate divides the cavity into two sections, so that workers can divide the installation area of ​​each component.

[0017] Preferably, it also includes a connecting pin, the two ends of which are connected to the upper outer frame and the lower outer frame respectively, and a gap is left between the connecting pin and the rectangular frame.

[0018] By adopting the above technical solution, the connecting pin can be used as a handle, making it convenient for staff to hold the connecting pin and move the battery casing, thus improving convenience.

[0019] Preferably, it also includes an exhaust fan, and a ventilation window is provided on the side wall of the rectangular frame. The ventilation window is used to connect the outside air and the air in the receiving cavity. The exhaust fan is provided on the ventilation window and is used to blow the heat in the receiving cavity to the outside. There are two ventilation windows arranged opposite each other.

[0020] By adopting the above technical solution, the battery may generate a certain amount of heat during use. When the exhaust fan is powered on, it starts to work and blows the heat in the containment cavity to the external environment through the vent window, thereby achieving heat dissipation and cooling.

[0021] Exhaust fans actively drive airflow, forcibly "drawing away" and expelling hot air from the area, while simultaneously forcing external cold air to "rapidly replenish" it, forming "forced convection." During this process, the heat carried by the hot air is continuously carried away, and the cold air continuously comes into contact with the heat source and absorbs heat, ultimately achieving rapid cooling.

[0022] Preferably, the outer surface of the connecting shell is coated with a paint layer.

[0023] By adopting the above technical solution, the paint layer can be epoxy resin paint or polyurethane paint, which can reduce physical damage to the battery shell and maintain the structural integrity of the shell.

[0024] In summary, this application includes at least one of the following beneficial technical effects: (1) By detachably setting the upper cover plate and the lower cover plate on the connecting shell, when the parts need to be repaired, the staff can remove the upper cover plate from the upper outer frame and remove the lower cover plate from the lower outer frame at the same time, so that the openings on both sides of the connecting shell are open, providing the staff with sufficient operating space and avoiding damage to the parts due to insufficient operating space.

[0025] (2) By setting a connecting pin, the staff can hold the connecting pin and move the battery housing, which improves the flexibility of moving the battery housing.

[0026] (3) By setting up an exhaust fan, the exhaust fan can generate wind after it runs, accelerate the air flow, break the inefficient state of natural convection, and the exhaust fan can cool down the internal components of the cavity through convection heat exchange.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0034] This application discloses a solar cell housing. (Refer to...) Figures 1 to 3 The battery casing includes an upper cover plate 1, a connecting shell 2, and a lower cover plate 3. The connecting shell 2 is hollow and forms a receiving cavity 15 for mounting the battery and circuit board assembly. In this embodiment, the outer surface of the connecting shell 2 is coated with a paint layer (not shown in the figure). The paint layer can be epoxy resin paint or polyurethane paint. The presence of the paint layer can reduce physical damage to the battery casing and maintain the structural integrity of the casing. The connecting shell 2 includes an upper outer frame 21, a rectangular frame 22, and a lower outer frame 23 that are interconnected. The rectangular frame 22 is used to connect the upper outer frame 21 and the lower outer frame 23. The upper outer frame 21 is located above the lower outer frame 23. The upper outer frame 21 has an opening, and the upper cover plate 1 is detachably connected to the upper outer frame 21. The lower outer frame 23 also has an opening, and the lower cover plate 3 is detachably connected to the lower outer frame 23. When the parts need to be repaired, the staff can remove the upper cover plate 1 from the upper outer frame 21 and the lower cover plate 3 from the lower outer frame 23 at the same time, so that the openings on both sides of the connecting shell 2 are open, providing the staff with enough operating space.

[0035] Specifically, the upper outer frame 21 has a first slot 4, and the upper cover plate 1 is snapped into the first slot 4, relying on friction to pre-fix the upper cover plate 1. An upper connecting block 5 is fixedly connected to the upper cover plate 1, and the upper connecting block 5 has a threaded hole. A corresponding upper through hole 6 is provided on the upper outer frame 21, and bolts pass through the upper through hole 6 and are screwed onto the upper connecting block 5. Several upper connecting blocks 5 are spaced apart, distributed along the edge of the upper cover plate 1. The upper outer frame 21 has an equal number of upper through holes 6, each corresponding to an upper connecting block 5. After the upper cover plate 1 is snapped into the first slot 4, the operator uses bolts to pass through the upper through holes 6 of the upper outer frame 21 and screw them onto the upper connecting blocks 5, relying on the bolt's screwing force to further fix the upper cover plate 1 and prevent it from falling off.

[0036] The lower outer frame 23 has a second slot 7, and the lower cover plate 3 is snapped into the second slot 7, relying on friction to pre-fix the lower cover plate 3. A lower connecting block 8 is fixedly connected to the lower cover plate 3, and the lower connecting block 8 has a threaded hole. The lower outer frame 23 has a through hole 9, the position of which corresponds to the lower connecting block 8. Bolts pass through the through holes 9 and are screwed onto the lower connecting block 8. Several lower connecting blocks 8 are spaced apart, and each lower connecting block 8 is distributed along the edge of the lower cover plate 3. The lower outer frame 23 has an equal number of through holes 9 as the number of lower connecting blocks 8, and each through hole 9 corresponds to a lower connecting block 8. After the lower cover plate 3 is snapped into the second slot 7, the operator uses bolts to pass through the through holes 9 of the lower outer frame 23 and screw them onto the lower connecting blocks 8, relying on the bolt's screw force to further fix the lower cover plate 3 and prevent the upper cover plate 1 from falling off.

[0037] In this embodiment, both the upper cover plate 1 and the lower cover plate 3 have raised textures 10 on their surfaces. The presence of raised textures 10 increases the surface roughness of the upper cover plate 1 and the lower cover plate 3, thereby increasing the static friction between the user's hands and the battery casing and improving stability during movement. A partition plate 11 is fixedly connected to the rectangular frame 22, located within the receiving cavity 15, and dividing the rectangular frame 22 into two compartments. A connecting pin 12 is also fixedly connected to the connecting shell 2, located outside the receiving cavity 15, and positioned along the height direction of the rectangular frame 22. The two ends of the connecting pin 12 are connected to the upper outer frame 21 and the lower outer frame 23, respectively. A gap exists between the connecting pin 12 and the rectangular frame 22, allowing fingers to pass through. The connecting pin 12 can serve as a handle, facilitating the user's grip on the connecting pin 12 and movement of the entire battery casing.

[0038] Combination Figure 4 In addition, a ventilation window 13 is provided on the side wall of the rectangular frame 22, which is used to connect the outside air and the air inside the housing 15. An exhaust fan 14 is also installed on the inner wall of the housing 15, which is used to blow the heat inside the housing 15 to the outside of the battery casing. There are two horizontally opposite ventilation windows 13, and an exhaust fan 14 is installed at each of the two ventilation windows 13. The battery may generate a certain amount of heat during use. At this time, the exhaust fan 14 can be controlled to operate. The exhaust fan 14 actively drives the airflow, forcibly expelling the hot air inside the housing 15, while forcing the outside cold air into the housing 15, thereby achieving cooling.

[0039] The implementation principle of a solar cell housing according to an embodiment of this application is as follows: the upper cover plate 1 and the lower cover plate 3 are detachably mounted on the connecting shell 2. When the component needs to be repaired, the staff can remove the upper cover plate 1 from the upper outer frame 21 and remove the lower cover plate 3 from the lower outer frame 23 at the same time, so that the openings on both sides of the connecting shell 2 are open, providing the staff with sufficient operating space and avoiding damage to the component due to insufficient operating space.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
