Description

Technical Field

[0001] This utility model relates to the field of hinge structures, and more specifically, to a hinge structure for an electrical appliance chassis and an electrical appliance chassis. Background Technology

[0002] Doors in electrical enclosures are typically opened using hinges. A hinge structure consists of two metal plates connected by a shaft, fixed to the door panel and the enclosure body respectively. This type of hinge provides basic door opening and closing functionality, is relatively inexpensive, and has a simple and easy-to-understand structure, making it commonly used in ordinary electrical enclosures and small equipment enclosures.

[0003] With the development of industrial technology, current industrial products and related fields have developed rapidly, further driving the demand for structural design capabilities. As a result, the demand for more aesthetically pleasing and efficient structures is also increasing, further promoting the trend of product appearance design towards simplicity and flatness.

[0004] Because the inner surface of the hinge blades in commonly used hinges is usually perpendicular to the pivot, the hinge will be recessed into the product surface when installing thin sheet metal parts, resulting in an uneven appearance and reducing the product's aesthetics. Moreover, since the products are usually outward-opening doors and the opening and closing of doors requires certain control over the interference of parts, hinges usually cannot be installed in a concealed manner in industrial design and will be exposed as an external component.

[0035] First Embodiment

[0036] This application provides a hinge structure for an electrical appliance chassis, used to connect two door panels 1 of the chassis. The hinge structure 2 includes a hinge shaft 3 and two blades 4. The axial direction of the hinge shaft 3 is consistent with the height direction of the two door panels 1. Each blade 4 corresponds to one door panel 1. The hinge shaft 3 and the two blades 4 are respectively located on the inner side of the two door panels 1. The inner side of the door panels 1 is the side facing each other when the two door panels 1 move towards each other. One end of each blade 4 is rotatably connected to the hinge shaft 3, and the other end is connected to the inner side of the corresponding door panel 1. The distance from the axis of the hinge shaft 3 to the side of each door panel 1 is greater than or equal to the sum of the thickness of the door panel 1 and the radius of the hinge shaft 3.

[0037] In conjunction with the above embodiments, such as Figures 1 to 6 As shown, the two door panels 1 are connected by multiple hinge structures 2. The axis of the hinge axis 3 of each hinge structure 2 is parallel to the height direction of the door panel 1, as shown below. Figure 4 The hinge structure 2 is installed on the inner side of each door panel 1, with the rotating end of each leaf 4 rotatably connected to the corresponding hinge shaft 3 and the fixed end of each leaf 4 fixedly connected to the inner side of the corresponding door panel 1. Furthermore, the distance between the inner side of each door panel 1 and the axis of the corresponding hinge shaft 3 is greater than or equal to the radius of the hinge shaft 3. This allows the hinge shaft 3 to be positioned more towards the inner side of the two door panels 1, thus concealing the protruding part 5 of the hinge shaft between the two door panels 1. When the two door panels 1 of the electrical enclosure are closed, the protruding part 5 of the hinge shaft is effectively hidden.

[0038] In existing hinge installation methods, such as Figure 9As shown, the center line of each leaf 4 passes the center of the hinge shaft 3, so that the left and right sides of the hinge shaft 3 are the hinge shaft protruding portions 5, and the hinge shaft protruding portions 5 are outward relative to the two door plates 1 after the door plate 1 is connected with the corresponding leaf 4, and the hidden installation of the hinge shaft protruding portions 5 cannot be realized. Compared with the existing hinge structure 2, the distance between the inner side of the door plate 1 and the axis of the hinge shaft 3 in the present application is specially set, that is, the distance between the inner side of each door plate 1 and the axis of the hinge shaft 3 is greater than or equal to the radius of the hinge shaft 3, so that the center of the corresponding leaf 4 does not pass the center of the hinge shaft 3, that is, the leaf 4 is eccentrically installed relative to the hinge shaft 3, and the hinge shaft 3 is arranged in a space more towards the inner sides of the two door plates 1, so that the hinge shaft protruding portions 5 are hidden between the two door plates 1.

[0039] Of course, the distance between the inner side of each door plate 1 and the axis of the hinge shaft 3 is equal to the radius of the hinge shaft 3, that is, Figure 5 As shown in the position relationship between the door plate 1 and the hinge shaft 3, at this time, the rotating end of each leaf 4 and the side surface of the corresponding door plate 1 connected with the hinge shaft 3 are tangent, and the installation of the door plate 1 and the hinge structure 2 at this time is more compact, and the installation space required by the hinge structure 2 can be reduced.

[0040] The hinge structure for the electrical appliance cabinet in the embodiment of the present application, when the two door plates 1 are in the open state and the inner sides of the two door plates 1 are in the same plane, the opposite inner sides of the two door plates 1 abut.

[0041] In combination with the above embodiment, when the inner sides of the two door plates 1 are in the same plane, the two door plates 1 of the electrical appliance cabinet are in the open state, and at this time, the opposite inner sides of the two door plates 1 abut, so that the two door plates 1 are installed more compactly, and the position space occupied by the two door plates 1 of the electrical appliance cabinet can be reduced. When the inner sides of the two door plates 1 are perpendicular to each other, that is, one door plate 1 is rotated by 90° or the angle between the two door plates 1 is 90° after relative rotation, the two door plates 1 of the electrical appliance cabinet are in the closed state.

[0042] The hinge structure for the electrical appliance cabinet in the embodiment of the present application, the hinge shaft 3 includes a rotating shaft 31 and a rotating sleeve 32, the axis of the rotating shaft 31 is consistent with the height direction of the two door plates 1, the rotating sleeve 32 is respectively and oppositely sleeved on the rotating shaft 31 along the axis direction of the rotating shaft 31, and the side of each rotating sleeve 32 away from the rotating shaft 31 is connected with the corresponding leaf 4; the distance between the side surface of each door plate 1 and the axis of the hinge shaft 31 is greater than or equal to the radius of the rotating sleeve 32.

[0043] In combination with the above embodiment, the rotating end of each of the two blades 4 is rotatably connected with the rotating shaft 31, and the rotating sleeve 32 is provided with a plurality of rotating sleeves 32 which are arranged in an upper and lower interval manner. The rotating end of each of the blades 4 is located between the corresponding two rotating sleeves 32, and the two rotating sleeves 32 are used to limit the corresponding blade 4, so as to avoid the movement of the blade 4 along the axis of the rotating shaft 31.

[0046] In combination with the above embodiment, as shown in Figure 7 and Figure 8 The difference between the first embodiment and the second embodiment is that the fixed end of each of the blades 4 of the second embodiment is mounted on the outer side of the corresponding door panel 1. The outer side is the side which is opposite to the other door panel 1 when the two door panels 1 rotate relative to each other. Compared with the first embodiment (the protruding part 5 of the hinge shaft is hidden when the two door panels 1 of the electric appliance cabinet are in a closed state), the second embodiment can hide the protruding part 5 of the hinge shaft when the two door panels 1 of the electric appliance cabinet are in an open state.
