[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] Example 1

[0032] Please combine Figure 1-6 as well as Figure 8-12The present invention discloses a double-door waterproof structure with exquisite design, simple structure, low processing cost and good waterproof sealing performance. The double-door waterproof structure is used to be installed on a cabinet to close the inner cavity of the cabinet or open the cabinet. Specifically, the double-door waterproof structure of this embodiment includes a first door panel 100 and a second door panel 200 that are relatively arranged and can cooperate to close or open the cabinet. The first door panel 100 and the second door panel 200 close the inner cavity of the cabinet when they are close to each other and fit (closed) to form a planar barrier. When the first door panel 100 and the second door panel 200 are away from each other, the inner cavity of the cabinet is connected to the external environment to open the cabinet. In this embodiment, the first door panel 100 and the second door panel 200 are both rectangular plate structures. The first door panel 100 includes a first horizontal edge extending along its width direction and a first vertical edge extending along its height direction. The second door panel 200 includes a second horizontal edge extending along its width direction and a second vertical edge extending along its height direction. A side of the first door panel 100 adjacent to the second door panel 200 is bent toward the inside of the cabinet to form a first U-shaped sealing portion with its opening facing away from the interior space of the cabinet. In other words, the portion of the first vertical edge adjacent to the second door panel 200 is bent to form the first U-shaped sealing portion. A first sealing member 110 is disposed within the first U-shaped sealing portion, and a first pressing portion is formed on the edge of the opening of the first U-shaped sealing portion adjacent to the second door panel 200. In other words, the portion of the first door panel 100 closest to the second door panel 200 protrudes to form the first pressing portion. A second pressing portion 210 corresponding to the first sealing member 110 and a recessed portion located adjacent to the second pressing portion 210 and corresponding to the first pressing portion are formed on the back of the second door panel 200. The second pressing portion 210 and the recessed portion together form a second U-shaped sealing portion, and a second sealing member 220 is disposed within the recessed portion.

[0033] When the first door panel 100 and the second door panel 200 are closed, the second pressing portion 210 elastically abuts against the first sealing member 110, and the first pressing portion elastically abuts against the second sealing member 220. It can also be understood that the first U-shaped sealing member and the second U-shaped sealing member are arranged relative to each other and staggered, so that a portion of the first U-shaped sealing member extends into the second U-shaped sealing member, and a portion of the second U-shaped sealing member extends into the first U-shaped sealing member. In this way, on the one hand, a waterproof structure with multiple corners similar to the shape of a Chinese character "J" is formed to extend the water path length during water seepage. On the other hand, the first U-shaped sealing member and the second U-shaped sealing member respectively squeeze and limit the seals arranged in each other, thereby achieving double waterproofing and improving the waterproofing effect.

[0034] It should be noted that, in this embodiment, the first U-shaped sealing portion and the first sealing member 110 both extend along the entire height direction of the first door panel 100, and the second U-shaped sealing portion and the second sealing member 220 both extend along the entire height direction of the second door panel 200. In this way, when the first door panel 100 and the second door panel 200 are closed, the first U-shaped sealing portion and the second U-shaped sealing portion can provide waterproof protection in the entire height direction of the double-door waterproof structure, thereby achieving full-height waterproofing of the mating parts of the first door panel 100 and the second door panel 200.

[0035] The first horizontal edge of the first door panel 100 is bent in sequence at a position adjacent to the second door panel 200 to form a first bent edge 120 perpendicular to the main surface of the first door panel 100 and extending toward the inner side of the cabinet, a second bent edge 130 perpendicular to the first bent edge 120 and extending toward the second door panel 200, and a third bent edge 140 perpendicular to the second bent edge 130 and extending away from the inner side of the cabinet. The first bent edge 120, the second bent edge 130 and the third bent edge 140 together form a first U-shaped sealing portion. In this embodiment, the second bent edge 130 has a dimension of 29 mm along the width direction of the first door panel 100, the third bent edge 140 has a dimension of 9 mm along the thickness direction of the first door panel 100, and the top of the third bent edge 140 extends upward by 5 mm. The length of the second sealing member 220 is adapted to the length of the third bent edge 140, so that the height of the sealing area is greater than the height of the first door panel 100, thereby improving the waterproof performance of the mating portion between the first door panel 100 and the second door panel 200. It can also be understood that the entire vertical edge (first vertical edge) of the first door panel 100 adjacent to the second door panel 200 is first bent toward the back of the first door panel 100, then bent toward the second door panel 200 along the width direction of the first door panel 100 for a second time, and finally bent toward the main surface of the first door panel 100 for a third time, thereby forming the first U-shaped sealing portion. The first seal 110 is attached to the surface of the second bent edge 130, and the end of the third bent edge 140 forms a first pressing portion. In other words, the first U-shaped seal forms a U-shaped groove, and the first seal 110 is received within this U-shaped groove to provide the first layer of waterproofing for the double-door waterproof structure. In this embodiment, the first seal 110 is a strip-shaped structure with a rectangular cross-section. It is cut from sealing foam and is affixed to the surface of the second bent edge 130 by glue. The main surface of the first door panel 100 is the side of the first door panel 100 that faces away from the interior of the cabinet, and the back surface of the first door panel 100 is the side of the first door panel 100 that is closer to the interior of the cabinet.

[0036] A second pressing portion 210 is provided on the second vertical edge adjacent to the first door panel 100. In one embodiment, a square tube extending in the height direction of the second door panel 200 is fixed to the back of the second door panel 200 adjacent to the first door panel 100 to form the second pressing portion 210 capable of squeezing the first sealing member 110. The square tube is welded or screwed to the second door panel 200. In another embodiment, the second horizontal edge of the second door panel 200 is bent in sequence adjacent to the first door panel 100 to form a fourth bent edge 211 perpendicular to the main surface of the second door panel 200 and extending toward the inner side of the cabinet, and a fifth bent edge 212 perpendicular to the fourth bent edge 211 and bent away from the first door panel 100. The surface of the fifth bent edge 212 forms the second pressing portion 210 that elastically abuts against the first sealing member 110. In this way, the second pressing portion 210 for pressing the first sealing member 110 can be obtained by simply bending the edge of the second door panel 200 twice in a row, thereby reducing the difficulty of forming the second pressing portion 210. In addition, in this embodiment, by bending the edge of the second door panel 200 twice, the width of the second pressing portion 210 is increased, thereby increasing the contact area between the second pressing portion 210 and the first sealing member 110, thereby improving the waterproof performance of the waterproof structure therein. It should be noted that the main surface of the second door panel 200 is the side of the second door panel 200 that faces away from the inner side of the cabinet, and the back side of the second door panel 200 is the side of the second door panel 200 that is close to the inner side of the cabinet.

[0037] In one embodiment, a sealing fixture 230 is further fixed to the back of the second door panel 200. One side of the sealing fixture 230 abuts against the end surface of the fifth bent edge 212 and, together with the fifth bent edge 212 and the fourth bent edge 211, forms a closed chamber 240. The sealing fixture 230 defines a groove 231, which opens toward the third bent edge 140 to form a recess. The second sealing member 220 is embedded in the groove 231. In this embodiment, the second sealing member 220 is a strip-shaped structure with a rectangular cross-section and is cut from sealing foam. The second sealing member 220 is fixed to the groove 231 of the sealing fixture 230 by gluing. The provision of the sealing fixture 230 on the second door panel 200 allows for positioning of the second sealing member 220 and limits the end of the fifth bent edge 212, thereby preventing the end of the fifth bent edge 212 from shaking. In this embodiment, the sealing fixture 230 has a U-shaped cross-section, or includes two spaced-apart fixing blocks, with a groove 231 formed between the two fixing blocks for accommodating the second sealing member 220. The fixing sealing member is machined from a metal material and is secured to the second door panel 200 by welding or screws.

[0038] Furthermore, in this embodiment, an L-shaped reinforcing rib 250 is provided in the closed chamber 240, and the L-shaped reinforcing rib 250 is fixedly connected to the back of the second door panel 200 and the side of the sealing fixing member 230 and abuts against the fifth bent edge 212. In this way, the sealing fixing member 230 limits the end of the fifth bent edge 212 and the L-shaped reinforcing rib 250 is formed on the inner side surface of the fifth bent edge 212 (the side of the fifth bent edge 212 located in the closed chamber 240), so that the strength of the fifth bent edge 212 can be improved, the deformation of the fifth bent edge 212 can be avoided, and the flatness of the fifth bent edge 212 when squeezed with the first sealing member 110 can be ensured to ensure the waterproof effect there.

[0039] In this embodiment, the dimension of the third bent edge 140 along the thickness direction of the first door panel 100 is smaller than the dimension of the first bent edge 120 along the thickness direction of the first door panel 100. The dimensions of the first seal 110, the second seal 220, the third bent edge 140 and the first pressing portion need to meet the requirements. When the first door panel 100 and the second door panel 200 are closed and form a planar barrier, the first pressing portion presses the second seal 220, and at the same time the second pressing portion 210 presses the first seal 110, and the edges of the first door panel 100 and the second door panel 200 do not warp, so as to ensure the waterproof performance of the first door panel 100 and the second door panel 200 when they are closed.

[0040] In addition, in one embodiment, the width of the first seal 110 is smaller than the distance between the first bending edge 120 and the third bending edge 140, the distance from the first seal 110 to the first bending edge 120 is greater than 0, the distance from the first seal 110 to the third bending edge 140 is greater than 0, and the distance from the first seal 110 to the third bending edge 140 is greater than the distance from the first seal 110 to the first bending edge 120, the outer side surface of the fourth bending edge 211 corresponds to the edge of the first seal 110 adjacent to the first bending edge 120, the second bending edge 130, the third bending edge 140, the second seal 220, the sealing fixing member 230 and the first seal 110 together form a moisture buffer chamber 260. In this embodiment, by making the distance from the first seal 110 to the first bent edge 120 greater than 0, and making the outer side surface of the fourth bent edge 211 correspond to the edge of the first seal 110 adjacent to the first bent edge 120, while ensuring that the fifth bent edge 212 and the first seal 110 are squeezed and waterproof, it is possible to avoid the fourth bent edge 211 and the first bent edge 120 from colliding when the first door panel 100 and the second door panel 200 are closed, thereby reducing the difficulty of closing the first door panel 100 and the second door panel 200. By forming a moisture buffer chamber 260 between the first seal 110 and the second seal 220, even when the first seal 110 fails, external moisture enters the moisture buffer chamber 260 through the gap between the first seal 110 and the fifth bent edge 212. The moisture buffer chamber 260 can effectively carry a portion of the water and form a water seal between the first seal 110 and the second seal 220. Due to the tension of the water, the external water is connected to the water in the moisture buffer chamber 260, and the water tension is used to bring the water in the moisture buffer chamber 260 out in time, thereby preventing the water in the moisture buffer chamber 260 from further eroding the connection between the second seal 220 and the third bent edge 140.

[0041] In order to ensure the flatness of the door panel, in one embodiment, a first reinforcing rib 150 extending along the height direction of the first door panel 100 is fixed to a portion of the first door panel 100 adjacent to the first U-shaped sealing portion, and a first gap 151 is formed between the first reinforcing rib 150 and the back side of the first door panel 100, and the dimension of the first gap 151 along the thickness direction of the first door panel 100 is greater than or equal to 5 mm; a second reinforcing rib 270 extending along the height direction of the second door panel 200 is fixed to a portion of the second door panel 200 adjacent to the second sealing member 220, and a second gap is formed between the second reinforcing rib 270 and the back side of the second door panel 200, and the dimension of the second gap along the thickness direction of the second door panel 200 is greater than or equal to 5 mm. Furthermore, in this embodiment, the top and bottom of the back side of the first door panel 100 are respectively provided with a first extrusion portion 101 and a second extrusion portion 102 extending along the width direction of the first door panel 100, and a third extrusion portion 103 is located on the side of the first door panel 100 facing away from the first U-shaped sealing portion and is vertically connected to the first extrusion portion 101 and the second extrusion portion 102, respectively; the top of the first reinforcement rib 150 is welded or screwed to the first extrusion portion 101, and the bottom of the first reinforcement rib 150 is welded or screwed to the second extrusion portion 102. The top and bottom of the back side of the second door panel 200 are respectively provided with a fourth extrusion part 201 and a fifth extrusion part 202 extending along the width direction of the second door panel 200, and a sixth extrusion part 203 located on the side of the second door panel 200 facing away from the first door panel 100 and vertically connected to the fourth extrusion part 201 and the fifth extrusion part 202, respectively; the top of the second reinforcement rib 270 is welded or screwed to the fourth extrusion part 201, and the bottom of the second reinforcement rib 270 is welded or screwed to the fifth extrusion part 202.

[0042] By arranging a first reinforcing rib 150 on the first door panel 100 and a second reinforcing rib 270 on the second door panel 200, the area on the first door panel 100 adjacent to the second door panel 200 and the area on the second door panel 200 adjacent to the first door panel 100 can be prevented from deformation, thereby ensuring the structural strength of the middle part of the double-door waterproof structure and the flatness of the first door panel 100 and the second door panel 200, so that the first pressing portion can be pressed against the second sealing member 220 and the second pressing portion 210 can be pressed against the first sealing member 110. At the same time, the first door panel 100 and the second door panel 200 can be pressed against the sealing structure on the cabinet to ensure the waterproof effect. Furthermore, in this embodiment, by forming a first gap 151 between the first reinforcing rib 150 and the back of the first door panel 100, and a second gap between the second reinforcing rib 270 and the back of the second door panel 200, water that penetrates through the top of the first door panel 100 and enters the back of the first door panel 100 is prevented from migrating to the first reinforcing rib 150 and dripping onto components within the cabinet. This also prevents water that penetrates through the top of the second door panel 200 and enters the back of the second door panel 200 from migrating to the second reinforcing rib 270 and dripping onto components within the cabinet, further enhancing the waterproofing effect. In this embodiment, the first reinforcing rib 150 is 20 mm long and 12 mm wide, while the second reinforcing rib 270 is 20 mm long and 20 mm wide. In other embodiments, the dimensions of the first and second reinforcing ribs 150 and 270 can be further adjusted.

[0043] In addition, the first door panel 100 is provided with a first door lock 104, a door lock fixing bracket 105 located next to the first door lock 104 and corresponding to the movable lock of the first door lock 104 to increase the height of the lock position, and the second door panel 200 is provided with a second door lock 204. The first door panel 100 and the second door panel 200 are locked to each other through the cooperation of the first door lock 104 and the second door lock 204. The first door lock and the second door lock can be any door panel lock on the market, and their specific structures are not described here. By providing the first door lock 104 and the second door lock 204, on the one hand, the stability of the structure of the first door panel 100 and the second door panel 200 after closing is achieved to prevent the cabinet from opening by itself. On the other hand, the first door lock 104 and the second door lock 204 limit the first door panel 100 and the second door panel 200 so that the first pressing portion presses the second sealing member 220 and the second pressing portion 210 presses the first sealing member 110, thereby ensuring the sealing effect of the double-door waterproof structure. The door lock fixing bracket 105 is a rectangular block structure, which is fixed to the back of the first door panel 100 by welding. By setting the door lock fixing bracket 105, the height of the buckle position of the first door lock 104 can be increased. When the first door panel 100 and the second door panel 200 are closed, the door lock fixing bracket 105 abuts against the components in the cabinet and presses the edge of the second door panel 200 toward the first door panel 100, which is conducive to locking the door lock and pressing the first door panel 100 and the second door panel 200, thereby further improving the waterproof effect.

[0044] Example 2

[0045] Please combine Figure 1 、 Figure 6 、 Figure 7 as well as Figure 9-12 The present invention also discloses a cabinet, which includes the above-mentioned double-door waterproof structure, wherein the double-door waterproof structure involved is exactly the same as the double-door waterproof structure of Example 1. Its structure can refer to the description of the double-door waterproof structure in Example 1 and will not be repeated here. The cabinet also includes a main chassis body 300 and a power module 400 accommodated in the main chassis body 300. The main surface of the main chassis body 300 is provided with an installation port 310 that is connected to the inner cavity of the main chassis body 300. The first door panel 100 and the second door panel 200 are arranged opposite to each other at the installation port 310 and are respectively pivotally connected to the main chassis body 300.
