Description

Technical Field

[0001] This utility model relates to the field of box-type product technology, and in particular to a protective box. Background Technology

[0002] Box-type structures are one of the most widely used product forms in the photovoltaic industry, encompassing key equipment such as photovoltaic inverters, photovoltaic combiner boxes, and energy storage products. With the continuous upgrading and iteration of photovoltaic products, the demand for grid connection and overcurrent protection on the AC side of photovoltaic systems is increasing. Against this backdrop, AC combiner boxes, as an emerging systemic product in the domestic photovoltaic category, especially for high-voltage, high-current combiner projects, exhibit significant differences in their door panel structure compared to traditional DC combiner boxes, photovoltaic inverters, or other similar products.

[0003] Traditional combiner box covers typically employ a left-right rotating opening design. While this facilitates maintenance and repair, its operating space is inherently limited by the left-right opening mechanism. Specifically, in narrow or complex installation environments, the left-right rotating opening may not be fully extended due to insufficient space, making it difficult for maintenance personnel to efficiently complete maintenance tasks and thus affecting the overall operating efficiency of the equipment.

[0004] Furthermore, photovoltaic products are mostly outdoor devices, exposed to the natural environment for extended periods. Under direct sunlight, solar ultraviolet radiation causes a significant increase in the temperature of the product casing, negatively impacting its functional efficiency. Additionally, during cloudy or rainy weather, if rainwater inadvertently enters the casing, it may cause water ingress, short circuits, and other risks, further threatening the stable operation and lifespan of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a protective box that can further improve the reliability and effectiveness of shielding and protection.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0008] The box-shaped enclosure has an internal cavity.

[0009] A cover is used to open and close the inner cavity. The top edge of the cover is hinged to the box body via a hinge. The cover can be flipped up relative to the box body via the hinge.

[0010] The upper eaves plate is located on the top of the box body and protrudes outward toward the side where the cover is located;

[0011] In the case where the cover is flipped open, the cover is suspended above the inner cavity, and there is a gap between the top edge of the cover and the box body, which is covered by the upper eaves.

[0012] Preferably, the support member includes a gas spring, which includes a fixed rod and a telescopic rod. The telescopic rod is telescopically mounted on the fixed rod. One of the fixed rod and the telescopic rod is hinged to the box body, and the other is hinged to the cover.

[0013] Preferably, the gas spring further includes a self-locking element for locking the telescopic rod after it extends outward.

[0014] Preferably, a locking member is provided between the housing and the cover, the locking member being used to fix the cover to the housing when the cover is closed.

[0015] Preferably, the locking component includes a buckle and a latch, one of which is fixed to the housing and the other to the cover, and the latch is used to engage with the buckle.

[0016] Preferably, the housing is provided with a sealing element on the outer edge of the inner cavity. The sealing element is used to abut against the cover when the cover is closed to seal the gap between the housing and the cover.

[0017] Preferably, the sealing element includes a sealing eave that protrudes from the outer edge of the inner cavity, and the end face of the cover facing the box body has an outer eave. When the cover is closed, the outer eave surrounds the sealing eave, and the outer side wall of the sealing eave abuts against the inner side wall of the outer eave. The end of the sealing eave abuts against the cover, and the end of the outer eave abuts against the box body.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] This embodiment provides a protective box. (Refer to...) Figures 1 to 2 As shown, the protective box includes a box body 1, a cover 2, and an upper eaves plate 4. The box body 1 has an inner cavity. The cover 2 is used to open and close the inner cavity. The top edge of the cover 2 is hinged to the box body 1 through a hinge 3. The cover 2 can be flipped up relative to the box body 1 through the hinge 3. The upper eaves plate 4 is located on the top of the box body 1 and protrudes outward toward the side where the cover 2 is located. When the cover 2 is flipped up and open, the cover 2 is suspended above the inner cavity, and a gap 101 is left between the top edge of the cover 2 and the box body 1. The upper eaves plate 4 covers the gap 101.

[0037] In this embodiment, the cover 2 can be flipped up onto the box body 1 via the hinge 3, without occupying space on the left and right sides of the box body 1, making it easy to operate. Furthermore, the flipped-up cover 2 can also shield the upper part of the inner cavity of the box body 1, providing sun and rain protection when it is open. By providing an upper eaves plate 4 at the top of the box body 1, with the upper eaves plate 4 protruding outwards towards the cover 2, the gap 101 between the top of the cover 2 and the box body 1 can be blocked when it is flipped up. This prevents sunlight from passing through the gap 101 and reaching the inner cavity, and also prevents rainwater from entering the inner cavity through the gap 101, further ensuring reliable and comprehensive shielding.

[0038] For example, the angle range of the cover 2 flipping up relative to the box 1 is set to 0°-90°.

[0039] In this embodiment, the protective box also includes a support member disposed between the box body 1 and the cover 2. The support member is used to support the cover 2 in the upward-flipped state after the cover 2 is flipped up. By providing the support member, the cover 2 can be fixedly supported at the target angle after it is flipped up, thereby achieving the upward-flipping positioning of the cover 2.

[0040] Specifically, the support component includes a gas spring 5, which includes a fixed rod 51 and a telescopic rod 52. The telescopic rod 52 is telescopically mounted on the fixed rod 51. One of the fixed rod 51 and the telescopic rod 52 is hinged to the housing 1, and the other is hinged to the cover 2. Specifically, the telescopic rod 52 of the gas spring 5 extends and retracts relative to the fixed rod 51, thereby driving the cover 2 to swing relative to the housing 1, thus realizing the automatic opening of the cover 2.

[0041] In this embodiment, gas springs 5 ​​are provided on both sides of the box 1 along its length. This arrangement ensures that the gas springs 5 ​​are subjected to uniform force, thereby improving the reliability and stability of the support.

[0042] Furthermore, the gas spring 5 also includes a self-locking component, which locks the telescopic rod 52 after it extends. Exemplarily, the self-locking components of the gas spring 5 mainly include mechanical self-locking components, pneumatic self-locking components, and traction self-locking components. Mechanical self-locking directly restricts the movement of the piston rod by setting a mechanical latch or ratchet mechanism. When locking is required, the latch engages the teeth on the piston rod, preventing it from retracting or extending. Pneumatic self-locking is achieved by controlling the gas flow inside the gas spring 5. For example, a valve is installed on the cylinder; when the valve is closed, the air chamber is sealed, and the internal pressure remains constant, thereby locking the position of the piston rod; opening the valve releases the pressure, allowing the piston rod to move freely. Traction self-locking is typically used in traction gas springs 5, where a specific traction mechanism generates a self-locking effect when a certain position is reached.

[0043] In some other alternative implementations, the support may also be configured as a telescopic cylinder, an electric push rod, or other similar components.

[0044] In this embodiment, a locking member 6 is also provided between the housing 1 and the cover 2. The locking member 6 is used to fix the cover 2 to the housing 1 when the cover 2 is closed. Specifically, by providing the locking member 6, when the cover 2 is closed, the locking member 6 can reliably fix the cover 2 to the housing 1, thereby achieving an effective seal when the cover 2 is closed.

[0045] Specifically, the locking component 6 includes a latch 61 and a locking tongue 62, one of which is fixed to the housing 1 and the other to the cover 2. The locking tongue 62 is used to engage with the latch 61. Specifically, multiple latches 61 are spaced apart on the housing 1, and multiple locking tongues 62 are correspondingly provided on the cover 2. Specifically, when the locking tongue 62 approaches the latch 61, the locking tongue 62 slides into the latch 61 and is locked by the snap spring inside the latch 61, forming a stable engaging engagement.

[0046] In some other alternative implementations, the locking element 6 may also be configured as a combination of a snap-fit ​​connector and a snap-fit ​​slot, or a combination of mutually attractive magnets.

[0047] In this embodiment, a sealing element is provided on the outer edge of the inner cavity of the housing 1. The sealing element is used to abut against the cover 2 when the cover 2 is closed, so as to seal the gap between the housing 1 and the cover 2. Specifically, by providing a sealing element, when the cover 2 is closed, the locking element 6 can reliably seal the gap between the housing 1 and the cover 2, further improving the reliability and effectiveness of the sealing effect.

[0048] Specifically, the sealing element includes a sealing eave 7 protruding from the outer edge of the inner cavity, and an outer eave 21 protruding from the end face of the cover 2 facing the housing 1. When the cover 2 is closed, the outer eave 21 surrounds the sealing eave 7, and the outer wall of the sealing eave 7 abuts against the inner wall of the outer eave 21. The end of the sealing eave 7 abuts against the cover 2, and the end of the outer eave 21 abuts against the housing 1. Specifically, the end of the sealing eave 7 faces the cover 2 and abuts against it, the outer wall of the sealing eave 7 abuts against the inner wall of the corresponding outer eave 21, and the end of the outer eave 21 faces the housing 1 and abuts against it. The end face of the cover 2, the outer eave 21, the end face of the housing 1, and the sealing eave 7 together form a labyrinth structure, thereby providing a sufficiently reliable sealing effect. When the cover 2 is closed, it effectively prevents moisture, dust, etc. from entering.

[0049] In this embodiment, the hinge 3 includes a support frame 31 and a hinge shaft 32. The support frame 31 is fixedly mounted on the housing 1, and the cover 2 is hinged to the support frame 31 via the hinge shaft 32. Specifically, the support frame 31 protrudes outward relative to the housing 1, providing reliable installation space for the hinge shaft 32. Both the support frame 31 and the hinge shaft 32 are disposed within the gap 101 between the top of the cover 2 and the housing 1.

[0050] In this embodiment, the housing 1 is provided with a water channel 11, which is used to drain water accumulated on the surface of the housing 1. Specifically, when applied to a rainy environment, rainwater can flow to the water channel 11 after hitting the housing 1, and finally be discharged out of the housing 1, thereby achieving effective drainage of rainwater and preventing rainwater from flowing randomly. Preferably, the water channel 11 is provided on the side of the housing 1, and the water channel 11 is arranged vertically through the housing 1.

[0051] In this embodiment, a lifting handle is provided on the sunshade cover and / or the box body 1. The lifting handle facilitates the picking up and moving of the protective box.

[0052] In this embodiment, a photovoltaic combiner assembly can be installed inside the protective box, i.e., the protective box is a photovoltaic combiner box. Specifically, the inner cavity may include devices such as DC circuit breakers, fuses, surge protectors, anti-reverse diodes, busbars, and terminals.

[0053] In summary, the protective box provided in this embodiment fully utilizes the shielding function through the combination of the shielding cover 2 and the upper eaves board 4, ensuring reliable and effective sunshade and waterproofing functions.

[0054] In some other alternative implementations, other equipment may be installed inside the protective enclosure, which will not be elaborated on here.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
