[0002] With the development of solar cell technology, solar cells are being used more and more widely in homes, such as in solar streetlights and solar cameras.

[0003] During the use of solar cells, a control chip is typically required for power management. The control chip and the solar cell are usually mounted on the solar cell casing, which in turn requires a bracket for secure installation. Currently, existing solar cell casings can only be mounted on a specific type of bracket and cannot be installed on other types. Due to the limited compatibility of existing solar cell casings, when users need to change the bracket type, they must also replace the solar cell casing. This not only increases the user's procurement costs but also severely restricts the installation flexibility of solar cells. Utility Model Content

[0030] This utility model proposes a solar cell casing.

[0031] Please refer to Figures 1 to 3 In one embodiment of the solar cell housing 100 of this utility model, the solar cell housing 100 includes a housing body 10 and a connecting part 30. The housing body 10 has a first surface 11 and a second surface 13 arranged opposite to each other. The first surface 11 is used to install the solar cell 300 and is fixedly connected to the second surface 13. The connecting part 30 is provided with a cavity 30a, which penetrates the first surface 11 and is used to install a control chip. On the side of the connecting part 30 away from the second surface 13, there are two first connecting structures 31. The two first connecting structures 31 are spaced apart and are used to connect to a first bracket. The connecting part 30 is provided with at least one second connecting structure 33, which is located between the two first connecting structures 31. The first connecting structures 31 are used to connect to a second bracket.

[0032] Understandably, the simultaneous installation of two connection structures allows for adaptation to different types of mounting brackets, improving the versatility and installation flexibility of the housing. Furthermore, the cavity 30a enables the integration of the solar cell 300 with the control circuit, reducing external wiring space and making the overall structure more compact. Additionally, the second connection structure 33 is located between the two first connection structures 31, achieving a staggered arrangement between the second and first connection structures 31. This avoids interference between the second and first connection structures 33, and the placement of the second connection structure 33 fully utilizes the unused space between the two first connection structures 31, effectively avoiding the occupation of other functional areas and achieving a compact structural design.

[0033] It should be noted that the first connecting structure 31 can be a sliding groove 31a, a claw, or other effective connecting structure. The second connecting structure 33 can be a threaded structure, a plug-in groove, or other effective connecting structure. The fixed connection between the shell body 10 and the connecting part 30 can be integrally formed, such as by injection molding or die casting; it can also be connected by welding; or it can be other effective fixed connection methods. The number of second connecting structures 33 provided in the connecting part 30 can be 1, 2, 3, 4, etc., and those skilled in the art can set it according to actual needs.

[0034] Please refer to Figure 3 In one embodiment of the solar cell housing 100 of this utility model, the first connecting structure 31 includes a connecting plate 311, a bending plate 313, and a limiting plate 315. The first side of the connecting plate 311 is connected to the connecting part 30, and the second side of the connecting plate 311 is bent and connected to the bending plate 313. The connecting plate 311, the bending plate 313, and the connecting part 30 form a sliding groove 31a, which is used to connect the first bracket. The third side of the connecting plate 311 is bent and connected to the limiting plate 315, and the limiting plate 315 is located at one end of the sliding groove 31a.

[0035] Understandably, the sliding groove 31a slides into the first bracket, allowing for convenient and quick installation or disassembly. The limiting plate 315, located at one end of the sliding groove 31a, restricts the sliding range of the bracket within the groove 31a, preventing the bracket from falling off and enhancing connection reliability. Furthermore, when the solar cell 300 is placed vertically, the limiting plate 315 also serves a load-bearing function. The first bracket is equipped with connecting blocks to match and connect to the two sliding grooves 31a.

[0036] It should be noted that the connection plate 311 can be integrally formed, welded, or other effective fixed connection methods when connecting the connecting part 30, connecting the bending plate 313, or connecting the limiting plate 315.

[0037] Please refer to Figure 3 In one embodiment of the solar cell housing 100 of this utility model, the second connecting structure 33 is a threaded hole structure. Understandably, the threaded hole structure is simple, has low processing costs, and facilitates later maintenance and bracket replacement. The second bracket is provided with threaded posts to match and connect the second connecting structure 33.

[0038] Please refer to Figure 1 and Figure 2 In one embodiment of the solar cell housing 100 of this utility model, the first surface 11 of the housing body 10 is recessed with a receiving groove 11a, which is used to install the solar cell 300, and the second surface 13 of the housing body 10 is protruded with a connecting part 30; the cavity 30a communicates with the receiving groove 11a.

[0039] Understandably, by setting up the receiving slot 11a, the installation and positioning of the solar cell 300 can be facilitated, thereby improving assembly efficiency.

[0040] Please refer to Figure 2 In one embodiment of the solar cell housing 100 of this utility model, a limiting groove 301a is provided in the cavity 30a, and a plurality of limiting protrusions 3011 are provided on the side wall of the limiting groove 301a, and the limiting protrusions 3011 extend along the depth direction of the limiting groove 301a.

[0041] Understandably, the limiting protrusion 3011 extending along the depth direction of the limiting groove 301a facilitates the installation of the control chip. The limiting protrusion 3011 fits tightly against the side of the control chip, enabling precise chip positioning and reducing chip loosening, thus ensuring circuit connection stability. Furthermore, the protrusion structure reduces the contact area between the chip and the groove wall, which is beneficial for chip heat dissipation.

[0042] Please refer to Figure 2 In one embodiment of the solar cell housing 100 of this utility model, a wire hole 301b is provided on one side wall of the cavity 30a, and a winding post 303 is provided on the bottom wall of the cavity 30a. The winding post 303 is located between the limiting groove 301a and the wire hole 301b.

[0043] Understandably, the wire can be wound around the winding post 303 and then pass through the wire hole 301b. With this configuration, the winding post 303 can bundle and fix the wire, preventing the wire from falling off or breaking due to pulling or vibration, thus ensuring the continuity of the circuit connection.

[0044] Please refer to Figure 2 In one embodiment of the solar cell housing 100 of this utility model, the bottom of the receiving groove 11a is recessed with a sink 111a, the cavity 30a is located in the sink 111a, and the bottom of the receiving groove 11a is used to bond the solar cell 300.

[0045] Understandably, the recess 111a lowers the height of the middle part of the receiving tank 11a to prevent the protrusion from affecting the mounting plane of the solar cell 300 and to ensure that the bottom of the receiving tank 11a is tightly bonded to the solar cell 300. Furthermore, using adhesive bonding to fix the solar cell 300 is simple to operate and easy to manufacture. Compared to mechanical fixing methods, adhesive bonding reduces damage to the surface of the solar cell 300.

[0046] Please refer to Figure 2In one embodiment of the solar cell housing 100 of this utility model, a plurality of spaced ribs 1111 are provided on the bottom of the sink 111a. The extending direction of the ribs 1111 is consistent with the extending direction of one side wall of the sink 111a, and the thickness of the middle of the ribs 1111 is greater than the thickness of its two ends.

[0047] Understandably, the bottom of the settling tank 111a is provided with multiple spaced ribs 1111, with the ribs 1111 being thicker in the middle and thinner at both ends. On the one hand, the ribs 1111 can enhance the structural strength of the shell body 10; on the other hand, the thicker middle and thinner ends of the ribs 1111 can support the middle part of the solar cell 300 and reduce the impact of the excessive thickness at both ends of the ribs 1111 on the adhesion between the solar cell 300 and the settling tank 11a.

[0048] Please refer to Figure 2 and Figure 4 In one embodiment of the solar cell housing 100 of this utility model, the bottom of the receiving groove 11a is provided with at least one vent hole 111b. Understandably, the vent hole 111b can serve to balance air pressure. Specifically, when the ambient temperature changes, the vent hole 111b can balance the air pressure inside and outside the receiving groove 11a, preventing the solar cell 300 from detaching from the housing body 10 due to pressure differences.

[0049] It should be noted that the number of vent holes 111b can be 1, 2, 3, 4, 5, etc., and those skilled in the art can set it according to actual needs.

[0050] Please refer to Figure 5 This utility model also proposes a solar power generation device 1000, including a solar cell 300 and a solar cell housing 100, with the solar cell 300 mounted on the solar cell housing 100. Understandably, the solar cell housing 100 can provide some protection for the solar cell 300, and it can also integrate the solar cell 300 with a control chip. It should be noted that the solar cell 300 can be a perovskite solar cell 300, a crystalline silicon solar cell 300, or other effective solar cell 300.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
