Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but must be based on the realization of ordinary skilled persons in the art. When the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0038] Please refer to Figures 1-10 The utility model provides a solar module with locking device 12, including solar junction box 10 and extension module 20, solar junction box 10 includes the casing 11 and sets up in the control circuit of casing 11 inside, extension module 20 includes the shell 21, sets up in the energy storage circuit of shell 21 inside and sets up in the conductive contact contact 22 of shell 21 outside,

[0039] Among them, the shell 21 still sets up recess 23, the casing 11 still sets up recess 111 and through slot 112, recess 111 sets up locking device 12, locking device 12 includes locking block 121, locking rod 122 and rotation column 123,

[0040] Locking block 121 sets up in through slot 112 and can along through slot 112 from one end of through slot 112 moves to the other end,

[0041] The rotating column 123 is fixedly connected to the inner wall of the groove 111, the middle part of the locking rod 122 is connected to the rotating column 123 and can rotate around the rotating column 123, one end of the locking rod 122 is located in front of the locking block 121, and the other end of the locking rod 122 can extend out of the groove 111 and retract into the groove 111;

[0042] When the locking block 121 moves along the through groove 112 from one end of the through groove 112 to the other end, one end of the locking rod 122 moves forward to make the locking rod 122 rotate in a forward direction around the rotating column 123, and the other end of the locking rod 122 retracts into the groove 111 from the recess 23, so that the expansion module 20 and the solar junction box 10 are separated;

[0043] When the locking block 121 moves along the through groove 112 from the other end of the through groove 112 to one end, one end of the locking rod 122 moves backward to make the locking rod 122 rotate in a reverse direction around the rotating column 123, and the other end of the locking rod 122 extends out of the groove 111 and is clamped into the recess 23, so that the expansion module 20 and the solar junction box 10 are connected, and the energy storage circuit is electrically connected with the control circuit through the conductive contact point 22.

[0044] Specifically, a user can manually rotate the locking block 121 to the locking position (one end of the through groove 112) or the unlocking position (the other end of the through groove 112). The position change of the locking block 121 causes the movement of one end of the locking rod 122, and the rotation of the locking rod 122 enables the other end of the locking rod 122 to be firmly clamped into or removed from the recess 23, thereby preventing the connection between the solar junction box 10 and the expansion module 20 from loosening or facilitating the disassembly of the expansion module 20. This mechanical locking mechanism provides physical fixation and avoids the problems of loosening or poor contact of the solar module in an outdoor environment.

[0045] Specifically, there are many ways to keep the other end of the locking rod 122 stably clamped into the recess 23, for example:

[0046] The elastic potential energy of a spring is used to make one end of the spring abut against the other end of the locking rod 122, so as to ensure the stability of the other end of the locking rod 122 in the recess 23;

[0047] An interference fit relationship is established between the shape of the recess 23 and the other end of the locking rod 122, so as to enhance the firmness of the connection;

[0048] A mechanical lock catch is adopted, which automatically clamps when the other end of the locking rod 122 is inserted into the recess 23, so as to ensure that the locking rod 122 will not accidentally fall off; or

[0049] The magnet is embedded in the locking rod 122 and the recess 23, the stability of the other end of the locking rod 122 is maintained by magnetic force adsorption, and quick connection and disconnection are provided.

[0050] Specifically, the connection mode of one end of the locking rod 122 and the locking block 121 also has many, and the movement mode of one end of the locking rod 122 will also be different for different connection modes. For example:

[0051] The external force that deforms the spring is used to move one end of the locking rod 122 forward, and the reset tendency of the spring is used to move one end of the locking rod 122 backward;

[0052] The direct mechanical connection relationship between one end of the locking rod 122 and the locking block 121 is established, the locking block 121 pushes one end of the locking rod 122 to move forward, and pulls one end of the locking rod 122 to move backward;

[0053] The polarity of the magnetic pole is changed to attract one end of the locking rod 122 to move forward and repel one end of the locking rod 122 to move backward.

[0054] These modes can be flexibly selected and combined according to specific application scenarios and design requirements to achieve the best locking effect and user experience, which will not be described one by one here.

[0055] Compared with the prior art, the solar module with the locking device 12 provided by the utility model, the locking device 12 adopts the combined design of the locking block 121, the locking rod 122 and the rotating column 123, in combination with the recess 111 and the through slot 112 on the shell 11 of the solar junction box 10 and the recess 23 on the shell 21 of the expansion module 20, so that the locking block 121 can move back and forth in the through slot 112 and cause the movement of one end of the locking rod 122, the locking rod 122 rotates around the rotating column 123, and the other end of the locking rod 122 performs the extension and retraction action in the recess 111. This design can effectively control the connection state between the solar junction box 10 and the expansion module 20, ensure that the other end of the locking rod 122 of the solar junction box 10 can be firmly clamped into the recess 23 of the expansion module 20 when connected, thereby preventing the connection from loosening due to external vibration or wind force and the like. In the connected state, a long-term stable electrical connection can be established between the expansion module 20 and the solar junction box 10, ensuring the durability and reliability of power transmission, and further improving the overall performance of the solar module. In addition, when using the solar module, the user only needs to simply move the locking block 121 to complete the connection and separation of the expansion module 20, without complicated operation steps, which significantly improves the user experience.

[0056] In some embodiments of the present application, the locking device 12 further comprises a resilient member, one end of which is connected to the inner wall of the groove 111, and the other end of which abuts against the other end of the locking rod 122 when the other end of the locking rod 122 is inserted into the recess 23.

[0057] Specifically, when the other end of the resilient member abuts against the other end of the locking rod 122, the resilient member is in a state of releasing elastic potential energy, which can be in a compressed or stretched state, depending on the design requirements and actual applications. Through this design, the resilient member can provide additional support to the other end of the locking rod 122, ensuring the stability of the locking rod 122 in the recess 23, and further enhancing the firmness of the connection between the solar junction box 10 and the extension module 20, preventing the connection from loosening due to external factors.

[0058] In some embodiments of the present application, the resilient member is a torsion spring 124, the rotating column 123 is inserted into the coil of the torsion spring 124, one end of the torsion spring 124 is connected to the inner wall of the groove 111, and the other end of the torsion spring 124 abuts against the other end of the locking rod 122 when the other end of the locking rod 122 is inserted into the recess 23.

[0059] Specifically, the torsion spring 124 is designed in a V-like shape, with its two legs spread apart to contact the inner wall of the groove 111 and the other end of the locking rod 122, respectively. This shape of the torsion spring 124 structure is relatively compact, which can provide a larger elastic force in a limited space, saving space while still maintaining good locking effect, and is particularly suitable for application in solar components with compact internal structure.

[0060] In some embodiments of the present application, the locking device 12 further comprises a sliding member, which comprises a rotating rod 125 and a hollow cylindrical body 126, the rotating rod 125 is connected to the other end of the locking rod 122 and located at the center of the cylindrical body 126, the cylindrical body 126 can rotate around the rotating rod 125, and when the other end of the locking rod 122 is inserted into the recess 23, the cylindrical body 126 rotates around the rotating rod 125 and the side surface of the cylindrical body 126 rolls on the inner wall of the recess 23.

[0061] Specifically, before the other end of the locking rod 122 is stably inserted into the recess 23, there is a process of gradually sliding into the recess 23. During this process, the cylindrical body 126 can roll on the inner wall of the recess 23, and the frictional resistance generated by rolling motion is much smaller than that generated by direct insertion due to the rough or uneven contact surface, thereby significantly reducing the resistance when the locking rod 122 slides into the recess 23, making the entire process of the other end of the locking rod 122 smoothly sliding into and being inserted into the recess 23 more smooth.

[0062] In some embodiments of the present application, the shell 21 is a square body, and the housing 11 is provided with a mounting position of the shell 21. When the shell 21 is mounted in the mounting position, the solar energy assembly is in a square structure.

[0063] Specifically, the square structure design makes the installation process of the solar energy assembly more intuitive, which conforms to the user's installation and disassembly habits. In addition, the shell 21 of the expansion module 20 is also a square body, and the edges and angles of the square body are uniform, which can be easily aligned and fixed during installation, thereby reducing the possibility of installation errors.

[0064] In some embodiments of the present application, the recess 23 includes a first position and a second position, the groove 111 includes a first groove and a second groove, the through groove 112 includes a left groove and a right groove, and the locking device 12 includes a first device and a second device.

[0065] The first position and the second position are symmetrically arranged on the left and right side walls of the shell 21. The positions of the first groove, the left groove, and the first device correspond to the position of the first position. The positions of the second groove, the right groove, and the second device correspond to the position of the second position.

[0066] Specifically, the solar energy assembly establishes two sets of symmetrical locking mechanisms to evenly distribute the locking force applied to the solar energy assembly, thereby reducing the possibility of displacement or tilting caused by unilateral locking. The symmetrical design not only provides advantages in function, but also improves the overall aesthetics of the product in vision, making the appearance of the solar energy assembly more coordinated and enhancing the market appeal of the product.

[0067] In some embodiments of the present application, the through groove 112 penetrates the housing 11 from top to bottom, and the locking block 121 protrudes from the through groove 112.

[0068] Specifically, the solar energy assembly may face various space limitations in actual use environment. The design that the through groove 112 penetrates the housing 11 from top to bottom enables the locking block 121 to protrude from the housing 11 from the top and the bottom, which facilitates the user to easily push the locking block 121 from any direction. This design enables the user to quickly find the appropriate operation mode according to the actual situation, thereby significantly enhancing the adaptability of the device.

[0069] In some embodiments of the present application, the locking block 121 comprises a first block 1211, a second block 1212 and a third block 1213, the upper end and the lower end of the second block 1212 are fixedly connected with the first block 1211 and the third block 1213 respectively, the width of the first block 1211 and the third block 1213 is smaller than that of the second block 1212, the first block 1211 extends above the through slot 112, and the third block 1213 extends below the through slot 112.

[0070] Specifically, the second block 1212 serves as an intermediate connecting part, which can effectively support the first block 1211 and the third block 1213, ensure the stability of the locking block 121 during use, and reduce deformation or loosening caused by external force. At the same time, the width of the first block 1211 and the third block 1213 is smaller, so that the user can more easily contact the locking block 121 during locking or unlocking operation, facilitate the user's finger to move, and improve the flexibility and convenience of operation.

[0071] In some embodiments of the present application, the first block 1211 and the third block 1213 are identical in shape.

[0072] Specifically, the first block 1211, the second block 1212 and the third block 1213 are integrally formed, which can eliminate the connection points between multiple components, reduce potential weaknesses, and also simplify the production process and reduce the assembly steps. Moreover, the first block 1211 and the third block 1213 are identical in shape, which ensures their consistency in function and performance. The user can obtain the same feeling and feedback during operation, thereby improving the comfort of use.

[0073] In some embodiments of the present application, the thickness of the shell 11 is less than or equal to 30mm, and the thickness of the outer shell 21 is the same as that of the shell 11.

[0074] Specifically, through proofing and actual application verification, the thickness of the shell 11 of the solar junction box 10 is less than or equal to 30mm, which is more in line with industry standards and people's use habits. At the same time, the thickness of the outer shell 21 is the same as that of the shell 11, which helps to improve the overall consistency of the solar assembly and ensure the coordination of the performance and appearance of each component.

[0075] The solar assembly with the locking device 12 provided by the embodiments of the present application can provide diversified power support for the final power receiving equipment stably and durably, and ensure efficient operation of the equipment under various environmental conditions. The design of the locking device 12 not only enhances the structural stability of the solar assembly, but also provides reliable protection for long-term use, prolongs the service life of the product, and makes the solar assembly more competitive in actual application.

[0076] It should be explained that the technical solutions of various embodiments of the present utility model can be combined with each other, but must be based on that a person having ordinary skill in the art can realize, when the combination of the technical solutions appears mutual contradiction or cannot be realized, it should be considered that the combination of the technical solutions does not exist, also is not within the range of the present utility model claimed to protect.

[0077] The above-mentioned is only part or preferred embodiment of the present utility model, therefore cannot limit the range of the present utility model protection whether it is text or drawing, is equivalent structural transformation under the concept of the whole of the present utility model with the present utility model specification and drawing contents, or direct / indirect application in other related technical field all are included in the range of the present utility model protection.
