Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module installation technology, and in particular relates to a connection locking device and a photovoltaic module. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, plays an increasingly important role in the global energy structure transformation. The construction of large-scale photovoltaic power plants typically involves the installation of a vast number of photovoltaic modules, which need to be securely fixed to pre-designed support systems to ensure long-term stable operation and resistance to various environmental factors (such as wind, snow, and temperature variations). Traditional connection methods mainly rely on standard fasteners such as bolts, nuts, and clamps. While these methods can guarantee the reliability of the connection to a certain extent, their inherent shortcomings are becoming increasingly apparent in large-scale installation operations.

[0003] In existing photovoltaic module installation practices, whether purely manual or partially mechanically assisted, the connection and tightening process is often a bottleneck for efficiency and a potential safety hazard. For example, during manual installation, workers typically need to align, insert, and tighten multiple bolts at heights or in inconvenient locations. This is not only labor-intensive and time-consuming, but also restricts operating space, easily leading to unstable installation quality and even safety accidents. Even with the assistance of robotic arms for handling and initial positioning of photovoltaic modules, the final locking and fixing step often still requires manual intervention, using tools to tighten the clamps or bolts. This process not only fails to completely eliminate reliance on manual labor but also limits further improvements in the overall automation level of installation. Furthermore, traditional threaded connections may loosen over long-term use due to vibration, thermal expansion and contraction, etc., requiring regular inspection and maintenance, increasing the operation and maintenance costs of the power plant.

[0004] Therefore, given the problems of cumbersome connection operations, low efficiency, high dependence on manual labor, insufficient automation, and potential safety risks in the current photovoltaic module installation process, there is an urgent need in this field for a new connection technology. Specifically, existing technologies have failed to effectively provide a connection device that, after two components to be connected are simply docked, achieves rapid and reliable automatic locking through the linkage of its internal structure. This automatic locking is accomplished by the joint action and coordination of the locking mechanisms in the two components involved in the docking, thereby ensuring the immediacy and stability of the connection, while also facilitating quick manual unlocking when necessary. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned technical problems by providing a connecting locking device and a photovoltaic module.

[0006] Firstly, a connecting locking device adopts the following technical solution:

[0007] A connecting latching device includes a connecting plate and at least one latching mechanism connected to the connecting plate, the latching mechanism including two latching components that can engage with each other;

[0008] The locking assembly includes:

[0009] The main body has a cavity;

[0010] A locking element is pivotally connected to the body and housed within the cavity; the locking element includes an operating part and a locking part connected thereto.

[0011] An elastic element connects the body and the operating part and applies force to both;

[0012] The two locking assemblies are mated together, and each locking member automatically pivots under the action of its respective elastic member, so that the two locking assemblies are in a locked state; the operating part is also used to manually overcome the action of the elastic member to release the locked state of the two locking assemblies.

[0013] Furthermore, the main body is provided with a mating part and a connector part extending along the length direction, and the mating parts of the two locking assemblies are inserted into the connector part to achieve a mating connection.

[0014] Furthermore, the cavity includes an inner limiting region and an outer limiting region connected thereto. The locking part is pivotally connected to the inner limiting region, and the operating part is at least partially movably disposed in the outer limiting region. The operating part extends at least partially outside the body and is operatively connected to the body through the elastic member.

[0015] Furthermore, the inner limiting area is provided with a limiting stop, and the locking part is provided with a limiting groove. The limiting stop cooperates with the limiting groove to limit the pivot angle range of the locking part.

[0016] Furthermore, the locking part has a guide structure. When the two locking components are mated together, the guide structure contacts the corresponding part of the body of the other locking component or the locking member, so as to guide the locking member to overcome the force of the elastic member and undergo temporary pivot displacement, and automatically return to the locked state after the mating is completed.

[0017] Furthermore, the connecting plate is provided with multiple mounting through holes for fixing the connecting locking device onto the bracket.

[0018] Furthermore, of the two locking components constituting the locking mechanism, one locking component is fixedly connected to the connecting plate, and the other locking component is adapted to be installed and fixed on the body of the component to be locked.

[0019] Furthermore, the connecting plate is provided with a plurality of locking mechanisms at intervals, and each locking mechanism includes two locking components that can dock and cooperate with each other to achieve synchronous locking of the object to be locked at multiple points.

[0020] Secondly, a photovoltaic module adopts the following technical solution:

[0021] A photovoltaic module includes a connecting locking device, a photovoltaic panel, and a bracket as described above, wherein the connecting locking device connects the photovoltaic panel and the bracket respectively.

[0022] Furthermore, the connecting locking device is fastened to the bracket via a connecting plate, and fastened to the main frame of the photovoltaic panel via a locking assembly. The photovoltaic panel and the bracket are locked together by the mating of two locking assemblies.

[0023] The beneficial effects of this utility model are:

[0024] This utility model provides a connecting locking device. Through its unique structure, particularly the automatic pivoting of each locking component under the action of its respective elastic element when the two locking components are mated, the two locking components quickly reach a locked state, significantly improving the convenience and efficiency of the connection operation. Compared with the existing technology that relies on manual tightening of bolts or pressure blocks one by one, this solution achieves automatic locking upon mating, greatly simplifying the installation steps and shortening the operation time. This automatic locking mechanism reduces the skill and labor intensity requirements of operators, improves the reliability and consistency of the connection, and avoids problems such as incomplete or overly tight connections due to differences in manual operation. Simultaneously, its manual unlocking function ensures the reversibility of the connection and the convenience of maintenance. Therefore, the connecting locking device provided by this utility model effectively solves the technical problems of cumbersome operation, low efficiency, low automation, and difficulty in guaranteeing connection quality in existing connection methods, providing an innovative solution for achieving fast, reliable, and standardized component connections.

The described embodiments should not be regarded as limitations on this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Unless otherwise defined, all technical and scientific terms used in the embodiments of this utility model have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of this utility model belong. The terminology used in the embodiments of this utility model is for the purpose of describing the embodiments of this utility model only and is not intended to limit the utility model.

[0034] Those skilled in the art should understand that, in the following description of the embodiments of this utility model, the sequence of numbers does not imply the order of execution. Some or all steps may be executed in parallel or sequentially. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this utility model.

[0035] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The singular forms "a" and "the" as used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0036] This embodiment provides a connecting locking device 1, including a connecting plate 10 and at least one locking mechanism 20 connected to the connecting plate 10. The locking mechanism 20 includes two locking components 30 that can dock and cooperate with each other.

[0037] Locking assembly 30 includes:

[0038] The main body 301 has a cavity 3011;

[0039] Locking member 302 is pivotally connected to body 301 and housed in cavity 3011; locking member 302 includes operating part 3021 and locking part 3022 connected thereto.

[0040] The elastic element 303 is connected between the body 301 and the operating part 3021 and applies force to both.

[0041] The two locking assemblies 30 are mated together, and each locking member 302 automatically pivots under the action of its respective elastic member 303, so that the two locking assemblies 30 are in a locked state; the operating part 3021 is also used to manually overcome the action of the elastic member 303 to release the locked state of the two locking assemblies 30.

[0042] Reference Figures 1 to 6 This embodiment provides a connecting locking device 1, the core of which is to achieve fast and reliable connection and locking between components. The connecting locking device 1 includes a connecting plate 10 and at least one locking mechanism 20 disposed on the connecting plate 10. In this embodiment, two locking mechanisms 20 are arranged in parallel on the connecting plate 10 to enhance the stability and load-bearing capacity of the connection. Each locking mechanism 20 consists of two locking components 30 that can dock and lock together.

[0043] Furthermore, each locking assembly 30 includes the following core components:

[0044] The main body 301 serves as the base for the locking assembly 30, and has an internal cavity 3011. This cavity 3011 provides the necessary space for the movement of the locking member 302.

[0045] A locking member 302 is pivotally connected to the body 301, and at least a portion thereof is accommodated or movable within the cavity 3011. Specifically, the locking member 302 includes an operating portion 3021 and a locking portion 3022 integrally formed with or securely connected to the operating portion 3021. The operating portion 3021 is the direct part for applying manual unlocking force, while the locking portion 3022 is responsible for forming a mechanical lock with the corresponding part of another locking assembly 30.

[0046] The elastic element 303 is a tension spring, with its two ends connected between the main body 301 and the operating part 3021, respectively. Through this connection, the elastic element 303 can apply a continuous force to the operating part 3021, thereby driving the entire locking element 302.

[0047] In actual use, when the two locking assemblies 30 are engaged, the locking members 302 inside each locking assembly 30 will automatically pivot under the force of their respective elastic members 303, allowing the locking portions 3022 of the two locking assemblies 30 to cooperate with each other, thereby enabling the two locking assemblies 30 to quickly and automatically enter and remain in the locked state. When it is necessary to unlock, an external force can be manually applied to the operating part 3021. This external force overcomes the preload of the elastic members 303, causing the locking members 302 to pivot in the opposite direction to the unlocked position, thereby releasing the locked state between the two locking assemblies 30.

[0048] In some embodiments, the body 301 is provided with a mating portion 3012 and a connector portion 3013 extending along the length direction. The mating portions 3012 and connector portions 3013 of the two locking assemblies 30 are inserted into each other to achieve a mating connection.

[0049] The main body 301 is specially provided with a mating portion 3012 and a connector portion 3013 extending along its length or a specific direction. When the two locking assemblies 30 are mated, the mating portion 3012 of one locking assembly 30 and the connector portion 3013 of the other locking assembly 30 form a corresponding insertion fit. For example, the connector portion 3013 of one assembly can be inserted into the receiving space formed by the mating portion 3012 of the other assembly, which helps to achieve preliminary guidance and positioning in the initial stage of mating, and ensures the accuracy and reliability of subsequent locking actions.

[0050] In some embodiments, the cavity 3011 includes an inner limiting region 30111 and an outer limiting region 30112 connected thereto. The locking part 3022 is pivotally connected to the inner limiting region 30111. The operating part 3021 is at least partially movably disposed in the outer limiting region 30112. The operating part 3021 extends at least partially outside the body 301 and is operatively connected to the body 301 through the elastic member 303.

[0051] The cavity 3011 can be specifically divided into an inner limiting region 30111 and an outer limiting region 30112 that communicates with the inner limiting region 30111. The main pivoting movement of the locking part 3022 occurs within the inner limiting region 30111, that is, its pivoting center is usually located in the inner limiting region 30111. The operating part 3021 is at least partially located in the outer limiting region 30112. For ease of manual operation, the operating part 3021 usually extends at least partially beyond the outer contour of the body 301. One end of the elastic member 303 is connected to the operating part 3021, and the other end is connected to a specific anchoring point of the body 301, thereby applying a continuous pulling or pressing force to the operating part 3021 to maintain the preset locked state of the locking member 302.

[0052] In some embodiments, the inner limiting region 30111 is provided with a limiting block 3014, and the locking part 3022 is provided with a limiting groove 30221. The limiting block 3014 cooperates with the limiting groove 30221 to limit the pivot angle range of the locking part 3022.

[0053] A limit stop 3014 may be provided inside the inner limiting region 30111. Correspondingly, a limit groove 30221 is formed on the locking part 3022. When the locking member 302 pivots, the limit stop 3014 contacts and engages with the edge of the limit groove 30221, thereby effectively limiting the pivot angle range of the locking part 3022, ensuring that it can move accurately between the preset locking position and unlocking position, and preventing excessive rotation.

[0054] In some embodiments, the locking part 3022 has a guide structure 30222. When the two locking components 30 are mated together, the guide structure 30222 contacts the corresponding part of the body 301 of the other locking component 30 or the locking member 302, so as to guide the locking member 302 to overcome the force of the elastic member 303 and undergo temporary pivot displacement, and automatically spring back to the locked state after the mating is completed.

[0055] Referring to the shape of the locking part 3022 in the figure, the locking part 3022 has a specific guide structure 30222. This guide structure 30222 can be a slope, an arc surface, or a cam profile. When the two locking assemblies 30 are mated, the guide structure 30222 of one locking assembly 30 will first contact a specific edge of the body 301 of the other locking assembly 30 or the corresponding guide portion of its locking member 302. Under the continuous action of the mating force, the guide structure 30222 can guide the locking member 302 to overcome the preset force of its own elastic member 303 and undergo a temporary pivoting displacement in the unlocking direction. Once fully engaged, the locking member 302 will automatically pivot in the opposite direction and spring back to the preset locking state under the rebound force of its elastic member 303, forming a stable lock with the other component.

[0056] In some embodiments, the connecting plate 10 is provided with a plurality of mounting through holes 101 for fixing the connecting locking device 1 to the bracket.

[0057] The connecting plate 10 has multiple mounting through holes 101 evenly or as needed. These mounting through holes 101 are used to pass through fasteners such as bolts and rivets, thereby firmly installing and fixing the entire connecting locking device 1 onto a bracket, support structure or base component.

[0058] In some embodiments, of the two locking components 30 constituting the locking mechanism 20, one locking component 30 is fixedly connected to the connecting plate 10, and the other locking component 30 is adapted to be installed and fixed on the body of the component to be locked.

[0059] Typically, of the two locking components 30 constituting a locking mechanism 20, one locking component 30 is fixedly connected to the connecting plate 10 by welding, screwing, or other permanent or semi-permanent connection methods, or is directly integrated with the connecting plate 10. The other locking component 30 is designed to be mounted and fixed to the body of the object to be locked. Thus, when the object to be locked is moved to align and engage with the connecting plate 10 on the bracket, both locking components 30 can be activated.

[0060] In some embodiments, a plurality of locking mechanisms 20 are provided at intervals on the connecting plate 10, and each locking mechanism 20 includes two locking components 30 that can engage and cooperate with each other to achieve synchronous locking of the object to be locked at multiple points.

[0061] The connecting plate 10 may have multiple (e.g., two or more) locking mechanisms 20 spaced apart along its length or according to specific layout requirements. Each locking mechanism 20, as described above, includes two locking components 30 that can engage with each other. Through this multi-point layout, when the component to be locked is engaged with the connecting plate 10, it can be simultaneously and synchronously locked with the bracket at multiple separate points, thereby greatly improving the overall strength, torsional resistance, and stability of the connection.

[0062] This embodiment provides a photovoltaic module, including a connecting locking device 1, a photovoltaic panel, and a bracket, wherein the connecting locking device 1 connects the photovoltaic panel and the bracket respectively.

[0063] This embodiment also provides a photovoltaic module that employs the connecting locking device 1 of any of the foregoing embodiments to achieve a quick and reliable connection between the photovoltaic panel and the support frame. Specifically, the photovoltaic module includes: the connecting locking device 1 described in any of the foregoing embodiments, one or more photovoltaic panels (typically referring to solar panel modules with frames), and a support frame (or mounting system) for supporting the photovoltaic panels. In this photovoltaic module, the key function of the connecting locking device 1 is to act as a bridge, connecting the photovoltaic panel and the support frame respectively, and forming a connection that can be quickly locked and unlocked.

[0064] In some embodiments, the connecting locking device 1 is fastened to the bracket via the connecting plate 10 and fastened to the main frame of the photovoltaic panel via a locking assembly 30. The photovoltaic panel and the bracket are locked together by the mating of the two locking assemblies 30.

[0065] The connecting locking device 1, through its connecting plate 10, utilizes the mounting through holes 101 on the connecting plate 10 and fasteners such as bolts to achieve a secure connection with a specific mounting part of the bracket (e.g., C-shaped steel, crossbeam, etc.). At the same time, another part constituting the locking mechanism 20, namely one or more locking assemblies 30 (corresponding to the number of locking mechanisms 20 on the connecting plate 10), is pre-installed and fixed on the edge or specific mounting point of the main frame (usually an aluminum alloy frame) of the photovoltaic panel.

[0066] During photovoltaic (PV) panel installation, workers or automated equipment move the PV panel with locking components 30 to a predetermined position on the support frame, aligning the locking components 30 on the PV panel with the corresponding locking components 30 on the support frame (fixed by the connecting plate 10). Subsequently, through a simple mating or pressing action, two (or more) pairs of locking components 30 automatically trigger the locking mechanism as in the aforementioned embodiment, achieving a quick and secure locking connection between the PV panel and the support frame. This design greatly simplifies the on-site installation process of PV panels and improves installation efficiency.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
