[0049] Example
[0050] The door panels of existing low-voltage cabinets are all formed by bending steel plates, and sealing protection is achieved by surface-to-surface abutment. However, when the door panels are deformed, the protection will fail and the protection performance requirements cannot be met.
[0051] The purpose of the utility model is to provide a low-voltage cabinet door panel structure 100 and a low-voltage cabinet 300, which can enable the low-voltage cabinet 300 to achieve better protection performance and improve the problem of protection failure when the door panel is deformed.
[0052] The following will be described in conjunction with the accompanying drawings, wherein Figure 1 A schematic diagram of the structure of a low-voltage cabinet provided in an embodiment of the utility model; Figure 2 A schematic structural diagram of a low-voltage cabinet door panel structure provided by an embodiment of the utility model; Figure 3 for Figure 2 The enlarged schematic diagram at A in the middle; Figure 4 for Figure 2 The enlarged schematic diagram of point B in the middle; Figure 5 A schematic diagram of the matching structure of the low-voltage cabinet door panel structure and the door frame provided in an embodiment of the utility model; Figure 6 A schematic diagram of the matching structure between the fifth folded edge of the low-voltage cabinet door panel structure and the door frame provided in an embodiment of the utility model.
[0053] Please refer to Figure 1 The utility model provides a low voltage cabinet 300, including a cabinet body 310 and a low voltage cabinet door plate structure 100. The cabinet body 310 is provided with a door frame 311. The low voltage cabinet door plate structure 100 is installed on the door frame 311.
[0054] It should be noted that generally, the cabinet 310 is formed by arranging a protective layer on the outer side of the frame structure. On the front side of the cabinet 310, a frame is generally used as a door frame 311.
[0055] In this embodiment, the low voltage cabinet 300 further includes a hinge. One side of the low voltage cabinet door plate structure 100 is connected to the door frame 311 via a hinge. The present application installs the low voltage cabinet door plate structure 100 via a hinge, which is convenient for installation.
[0056] Please refer to Figures 2 to 6 In this embodiment, the low-voltage cabinet door panel structure 100 includes a door panel body 110 and a sealing folded edge 130. The sealing folded edge 130 is arranged at the periphery of the door panel body 110. The sealing folded edge 130 includes a first folded edge 131, a second folded edge 133 and a third folded edge 135. The first folded edge 131 is connected to the door panel body 110 and is bent toward the inner side of the door panel body 110. The second folded edge 133 is connected to the first folded edge 131 and is bent toward the center of the door panel body 110. The second folded edge 133 is used to abut against the outer side wall of the door frame 311. The third folded edge 135 is connected to the second folded edge 133 and is bent in a direction away from the door panel body 110. It can extend to the inner side of the door frame 311. The third folded edge 135 is used to cooperate with the inner side wall of the door frame 311.
[0057] The present application sets a second folded edge 133 for abutting and sealing with the outer side wall of the door frame 311, and sets a third folded edge 135 for sealing with the inner side wall of the door frame 311. In this way, when the door panel body 110 is deformed, the sealing of the second folded edge 133 and the outer side of the door frame 311 will be achieved, and the sealing of the third folded edge 135 and the inner side wall of the door frame 311 will not be affected, thereby achieving double sealing, so that the required sealing protection, such as IP40, can be achieved even when the door panel body 110 is deformed. Secondly, by setting the first folded edge 131, the second folded edge 133 and the third folded edge 135, the mechanical properties of the door panel will be enhanced, thereby improving the problem of deformation of the door panel body 110.
[0058] In this embodiment, the door panel includes a first side 111 and a second side 113 opposite to each other and a third side 115 and a fourth side 117 opposite to each other. The first side 111 is hinged to the door frame 311 through a hinge, and the second side 113, the third side 115 and the fourth side 117 are all provided with a first folded edge 131, a second folded edge 133 and a third folded edge 135.
[0059] Sealing folds 130 are provided on the second side 113 , the third side 115 and the fourth side 117 , so that the door panel can be more conveniently installed on the door frame 311 .
[0060] Please refer to Figures 2 to 6 In this embodiment, the width of the third fold 135 ranges from 5 mm to 15 mm. For example, 5.5, 8, 11, 11, 3, etc. vertically. As long as the door panel can be opened and closed normally, it can be ensured that the door panel body 110 and the door frame 311 can better cooperate to achieve sealing when the door panel is deformed.
[0061] For example, when testing the IP40 protection level, even if a 1 mm probe can be inserted into the gap between the second folded edge 133 and the door frame 311, it will be blocked by the third folded edge 135, so that the IP40 protection level can still be achieved.
[0062] In this embodiment, the first folded edge 131 is perpendicular to the door panel body 110, the second folded edge 133 is perpendicular to the first folded edge 131, and the third folded edge 135 is perpendicular to the second folded edge 133. In this way, better sealing can be achieved and mechanical strength can be increased.
[0063] Please refer to Figures 2 to 6 In this embodiment, the low-voltage cabinet door panel structure 100 further includes a fourth folded edge 141 and a fifth folded edge 143. The fourth folded edge 141 is connected to the first side 111 and is bent toward the inner side of the door panel body 110. The fifth folded edge 143 is connected to the fourth folded edge 141, and the fifth folded edge 143 is bent toward the center of the door panel body 110, and the fifth folded edge 143 can be in contact with the door frame 311 to achieve sealing.
[0064] In this embodiment, a fourth folded edge 141 and a fifth folded edge 143 are provided on one side of the door panel body 110 for connecting with the frame, so that the door can be conveniently closed and opened while achieving sealing.
[0065] In this embodiment, the fourth fold 141 is perpendicular to the door panel body 110, and the angle between the fourth fold 141 and the fifth fold 143 is 45°. The fourth fold 141 and the fifth fold 143 are provided in this application so that the hinge can be installed and the door can be opened and closed easily while achieving sealing.
[0066] In this embodiment, the door panel body 110 , the first folded edge 131 , the second folded edge 133 , the third folded edge 135 , the fourth folded edge 141 , and the fifth folded edge 143 are integrally formed.
[0067] It can be understood that the door panel structure is made of a whole piece of steel plate through stamping, bending and other processes.
[0068] In summary, the working principle and beneficial effects of a low-voltage cabinet door panel structure 100 and a low-voltage cabinet 300 provided by the embodiment of the utility model include:
[0069] In this embodiment, the second folded edge 133 is provided for abutting and sealing with the outer side wall of the door frame 311, and the third folded edge 135 is provided for cooperating and sealing with the inner side wall of the door frame 311. In this way, when the door panel body 110 is deformed, the second folded edge 133 and the outer side of the door frame 311 can be sealed, and the cooperating and sealing of the third folded edge 135 and the inner side wall of the door frame 311 will not be affected, so that the required sealing protection, for example, IP40, can be achieved even when the door panel body 110 is deformed. Secondly, by providing the first folded edge 131, the second folded edge 133 and the third folded edge 135, the mechanical properties of the door panel can be enhanced, thereby improving the problem of deformation of the door panel body 110.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
