The door body has an opening position and a closing position relative to the opening. By designing a special hinge mechanism and matching with the metal plate structure design of the door body and the cabinet body, the center of the rotating shaft in the door body opening and closing process is promoted to deviate towards the inner side of the width direction of the cabinet body, so that when the door body is opened, the outer side door body structure exceeding the center part of the rotating shaft translates towards the defined range of the width of the cabinet body; therefore, the volume of the door body exceeding the width of the cabinet body is limited within a certain range when the door is opened. Simulation results show that the cabinet door structure satisfies smooth opening and closing of the cabinet door of the industrial and commercial energy storage outdoor cabinet with large arc angle transition in a cabinet combination scene.

Description

Technical Field

[0001] The utility model relates to a cabinet door structure, in particular to a cabinet door structure of an industrial and commercial energy storage outdoor cabinet, belonging to the field of industrial and commercial energy storage equipment. Background Art

[0002] Industrial and commercial energy storage is a typical application of distributed energy storage systems on the user side. Its characteristics are that it is close to the distributed photovoltaic power source and the load center. It can not only effectively improve the clean energy consumption rate, but also effectively reduce the transmission loss of electric energy. With the centralized management of industrial and commercial areas, the application of industrial and commercial energy storage stations is becoming more and more extensive in life. In addition to the single-use energy storage integrated machine, more and more application scenarios require industrial and commercial energy storage equipment to meet both single use and cabinet use, so as to meet different energy storage requirements.

[0003] In the prior art, most industrial and commercial energy storage outdoor cabinets adopt a square and angular design, and the cabinet door is usually directly connected to the width edge of the cabinet body with a pivot hinge that can rotate coaxially. There are few designs with arcs on the door body, especially large arc angle transitions. When encountering such a design, the large thickness and special arc angle of the cabinet door will cause the cabinet door to occupy a large amount of activity space during the opening and closing process of the door body, and may interfere with the cabinet bodies placed on both sides, making it impossible to achieve smooth opening and closing of the door leaf. Utility Model Content

[0004] In order to solve the shortcomings of the above-mentioned technology, the utility model provides a cabinet door structure for an industrial and commercial energy storage outdoor cabinet. When the outdoor cabinet is designed as a double-door and the cabinet door edge has an arc transition angle, the space occupied by the door body during opening and closing is reduced through structural design, so that the cabinet door opening and closing is not affected by the cabinet bodies on both sides.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cabinet door structure of an industrial and commercial energy storage outdoor cabinet, including a cabinet body, which also includes a hinge assembly. An opening is provided on one side of the cabinet body. The opening of the cabinet body is pivotally connected to the door body by at least one hinge assembly. The door body can open or close the opening on the cabinet body by pivoting, and the door body has an open position and a closed position relative to the opening.

[0006] Preferably, the hinge assembly includes a static hinge and a movable hinge which are arranged correspondingly, and the movable hinge is rotatably connected to the static hinge via a hinge pin.

[0007] Preferably, the pivot axes of the static hinge and the movable hinge coincide with the vertical axis of the hinge pin, and the door body drives the movable hinge to rotate around the vertical axis centered on the hinge pin.

[0008] Preferably, the cabinet body has a cabinet body sealing surface frame at the opening, and the door body has a door body sealing surface frame on the side facing the opening.

[0009] Preferably, the static hinge is fixedly mounted on the cabinet body, and the movable hinge is fixedly connected to the door body sealing surface frame via fasteners.

[0010] Preferably, a circular arc edge is formed on one side of the door body close to the cabinet body, and a transition angle edge of the circular arc edge of the door body is tangent to the side edge of the cabinet body.

[0011] Preferably, the opening and closing angle of the door body is 95°-105°.

[0012] Preferably, there are two door bodies, and when the two door bodies are closed at the same time, the opening of the cabinet is sealed.

[0013] The utility model designs a special hinge mechanism and matches the sheet metal structure design of the door and cabinet, so that the center of the rotating shaft during the door opening and closing process is offset inward in the direction of the cabinet width, so that when the door is opened, the outer door structure beyond the center of the rotating shaft moves horizontally within the defined range of the cabinet width, thereby limiting the volume of the door beyond the defined width of the cabinet when the door is opened to a certain range. The simulation results show that this cabinet door structure meets the requirements of the smooth opening and closing of the industrial and commercial energy storage outdoor cabinet doors with large arc angle transitions in the cabinet combination scenario.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 The cabinet door structure of an industrial and commercial energy storage outdoor cabinet shown in the figure includes a cabinet body 1, and the cabinet body 1 is provided with equipment such as a battery pack, a control system, a liquid cooling system, and a fire protection system required for the energy storage system. An opening is provided on one side of the cabinet body 1 to facilitate installation, maintenance, and repair of related equipment inside the cabinet body 1 through the opening. Correspondingly, the door body 2 is pivotally connected to the cabinet body 1 through at least one hinge assembly 3, so that the door body 2 can open or close the opening on the cabinet body 1 by pivoting, and the door body 2 has at least an open position and a closed position relative to the opening on the cabinet body 1 (that is, the door body can be in an open state or a closed state).

[0022] like Figure 1 As shown in the figure, the industrial and commercial energy storage outdoor cabinet is provided with an opening on the front side of the cabinet (i.e., the side facing the operator when the operator operates the internal equipment), and the door body 2 is pivotally connected to the front side of the cabinet body 1 through four hinge assemblies 3. In actual use, it is not limited to the front opening, and openings can also be provided at other positions of the cabinet body 1, and the installation position of the door body 2 can be adjusted accordingly.

[0023] In order to reduce the space occupied by the door body 2 during the opening and closing process, thereby facilitating smoother opening and closing of the door body 2 when cabinets are combined, the utility model provides a new hinge assembly 3 to realize the pivot connection between the door body 2 and the cabinet body 1. Specifically, the hinge assembly 3 includes a static hinge 31, a movable hinge 32 and a hinge pin 33 (the hinge pin acts as a pivot axis).

[0024] In this embodiment, combined with Figure 2 and Figure 4 As shown, the hinge assembly 3 has a corresponding static hinge 31 and a movable hinge 32, wherein the static hinge 31 is fixed to the cabinet 1 by welding. Furthermore, in order to realize the pivot connection between the movable hinge 32 and the cabinet 1, as shown in FIG. Figure 2 As shown, the movable hinge 32 is rotatably connected to the static hinge 31 through the hinge pin 33, and the pivot axis of the static hinge 31 and the movable hinge 32 coincides with the axis of the hinge pin 33, that is, Figure 2The vertical axis 4 shown in FIG. Further, the movable hinge 32 is fixedly connected to the door body sealing surface frame 21 of the door body 2 by connecting fasteners (connectors such as bolts can be used to achieve connection).

[0025] Based on the above settings, assuming that in the initial state, the door body 2 is in the closed position, at this time, Figure 4 From the cross-sectional view when the door body 2 is in the closed position, it can be seen that the movable hinge 32, the door body sealing surface frame 21 and the cabinet body sealing surface frame 11 are basically parallel to the plane where the movable hinge 32, the door body 2 is close to the cabinet body 1. A circular arc edge is formed on the side of the door body 2 close to the cabinet body 1, and the arc transition angle edge of the side of the door body 2 is basically tangent to the side of the cabinet body 1.

[0026] When the door body 2 needs to be opened, it is only necessary to operate the door body 2, and drive the movable hinge 32 to rotate around the vertical axis 4 centered on the hinge pin 33 through the door body 2. At this time, based on the fact that the vertical axis 4 is located on the inner side of the width direction boundary of the cabinet, the outer structure of the door body 2 beyond the center part of the rotating shaft (hinge pin) can be translated into the range defined by the width of the cabinet 1, thereby reducing the space occupied by the door body 2 during the opening process.

[0027] On this basis, if Figure 3 As shown in the figure, a is the moving track of the door body beyond the axis, and b is the boundary line in the cabinet width direction. Based on the arc length and angle data of the arc transition angle of the door body 2, the specific position of the vertical axis 4 can be determined through numerical calculation and reasoning, and the outdoor cabinets can be combined, and the door body 2 can also be opened and closed normally without interfering with other cabinets. Figure 1 As shown, the middle is an outdoor cabinet in an open state, and the two sides are outdoor cabinets in a closed state. Based on the hinge assembly design of the present application, the cabinet door structure provided by the present application meets the switch requirements when outdoor cabinets are used in combination.

[0028] Furthermore, by adjusting the position of the vertical axis 4, the maximum angle range in which the door body 2 can be opened can also be determined. In this embodiment, the door body 2 can achieve an opening and closing of 100°, which meets the installation and daily maintenance and inspection requirements of the internal equipment of the outdoor cabinet.

[0029] The purpose of the utility model is to provide a cabinet door structure for an industrial and commercial energy storage outdoor cabinet. By forming a transition edge with a large arc angle on the cabinet door, the movable space of the cabinet door during the opening and closing process is limited to avoid interference with the cabinet bodies placed on both sides, thereby achieving smooth opening and closing of the door leaf.

[0030] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
