Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage technology, and in particular to a cabinet door terminal cover for an energy storage machine. Background Technology
[0002] Energy storage devices are core equipment used to store and dispatch electrical energy generated from new energy sources. They convert direct current (DC) into alternating current (AC) and boost the voltage before connecting it to the power grid, thereby achieving efficient energy utilization.
[0003] Most energy storage units on the market use screws or welding to fix the terminal covers to the cabinet door, which affects the convenience of daily maintenance. Utility Model Content
[0004] To address the aforementioned problems, this invention provides a terminal cover for the cabinet door of an energy storage machine, which avoids the use of screws or welding as in existing technologies to fix the terminal cover, thereby improving the ease of operation for daily maintenance.
[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0006] This utility model provides a terminal cover for a cabinet door of an energy storage machine, including a cabinet door, a terminal cover rotatably disposed on the cabinet door, and a rotating buckle unit disposed between the cabinet door and the terminal cover; the rotating buckle unit includes a rotating buckle and a snap-fit groove; and rotating the rotating buckle switches between a locked position engaged with the snap-fit groove and an unlocked position away from the snap-fit groove, thereby switching the terminal cover between a covered position covering the terminals on the cabinet door and an open position exposing the terminals on the cabinet door.
[0007] Furthermore, the rotating buckle has a latching part, a handle part, and a connecting part connecting the latching part and the handle part, and the connecting part is rotatably mounted on the cabinet door; one end of the terminal cover is pivotally connected to the cabinet door through a rotating connector, and the other end has a latching groove for engaging with the latching part, and the latching part is detachably latched into the latching groove; the cabinet door has a clearance groove for accommodating the movement trajectory of the latching part; and when locked, the latching groove communicates with the clearance groove; rotating the handle part drives the latching part to rotate from the clearance groove away from the latching groove to the latching groove, thereby locking the end of the terminal cover away from the rotating connector to the cabinet door.
[0008] Furthermore, an elastic element is provided between the rotating buckle and the cabinet door, and the elastic element uses its own elasticity to restrict the buckle part within the snap-fit groove.
[0009] Furthermore, the elastic element is an elastic EVA cushioning cotton layer, which is disposed on the side of the cabinet door facing the terminal cover; when locked, the terminal cover elastically abuts against the EVA cushioning cotton layer, and the EVA cushioning cotton layer forms a rebound force restriction to ensure that the terminal cover elastically abuts against the buckle part, thereby restricting the buckle part in the snap-fit groove.
[0010] Furthermore, the clearance groove and the snap-fit groove are both arc-shaped grooves.
[0011] Furthermore, the terminal cover is a box structure with a one-way opening.
[0012] Furthermore, the terminal cover is square.
[0013] Furthermore, the end of the terminal cover opposite to the rotating buckle unit is provided with an elastic plug for cushioning.
[0014] Furthermore, the elastic plug is a silicone plug.
[0015] Furthermore, a damping fit is formed between the rotating connector and the terminal cover to slow down the rotation speed of the terminal cover during unlocking.
[0016] The technical solution provided by this utility model has the following beneficial effects:
[0017] By rotating the rotating buckle, the buckle can be switched between a locked position engaged with the slot and an unlocked position away from the slot. This allows the terminal cover to switch between a covered position that conceals the terminals on the cabinet door and an open position that exposes the terminals on the cabinet door. Therefore, when the terminals need maintenance, the terminal cover can be opened simply by unscrewing the rotating buckle. This avoids the need for screwing or welding, which are used in existing technologies, and also improves the ease of operation for daily maintenance. Attached Figure Description

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0023] Reference Figures 1 to 3 This embodiment provides a cabinet door terminal cover for an energy storage machine, including a cabinet door 1, a rotatable terminal cover 2 disposed on the cabinet door 1, and two rotating buckle units 3 disposed between the cabinet door 1 and the terminal cover 2.
[0024] like Figure 1 and Figure 2 As shown, each rotating buckle unit 3 includes a rotating buckle 31 and a snap-fit groove 32. Rotating the rotating buckle 31 allows the rotating buckle 31 to switch between a locked position where it is snapped into the snap-fit groove 32 and an unlocked position away from the snap-fit groove 32, thereby allowing the terminal cover 2 to switch between a covered position that covers the terminals on the cabinet door 1 and an open position that exposes the terminals on the cabinet door 1.
[0025] In this embodiment, the rotating buckle 31 has a buckle portion 311, a handle portion 313, and a connecting portion 312 connected between the buckle portion 311 and the handle portion 313. The connecting portion 312 is rotatably mounted on the cabinet door 1 via a pin.
[0026] The lower end of terminal cover 2 is via, as shown in... Figure 3 The rotating connector 5 shown is pivotally connected to the cabinet door 1. Two engaging grooves 32 are provided on the other upper end of the terminal cover 2 for engaging with the latching part 311. The latching part 311 can be detachably engaged with its corresponding engaging groove 32. The cabinet door 1 has two clearance grooves 11 to allow for the movement trajectory of the latching part 311. When locked, the engaging groove 32 connects to its corresponding clearance groove 11, and both the clearance groove 11 and the engaging groove 32 are arc-shaped grooves to ensure smooth arc-shaped movement of the latching part 311 between the engaging groove 32 and the clearance groove 11, while also guiding the movement of the latching part 311. Of course, the lengths of the engaging groove 32 and the clearance groove 11 are fixed to limit the rotation angle of the latching part 311 within a preset range.
[0027] When it is necessary to open the terminal cover 2 for routine maintenance of the terminals, the rotating buckle 31 is initially in the locked position. Therefore, first rotate the handle 313 to move the latch 311 away from the latching groove 32 until it is fully screwed into the clearance groove 11 away from the latching groove 32, thereby unlocking the upper end of the terminal cover 2 from the cabinet door 1. Then, rotate the terminal cover 2 downwards to expose the terminals, thus facilitating subsequent maintenance operations. At the same time, the rotating buckle 31 is in the unlocked position and the terminal cover 2 is in the position as shown in the picture. Figure 3 The position shown is where it is turned open.
[0028] After routine maintenance is completed, first rotate the terminal cover 2 upwards until it is pressed against the cabinet door 1. Then, rotate the handle 313 in the opposite direction to rotate the latch 311 from the clearance slot 11 away from the latching slot 32 into the latching slot 32, thereby locking the upper end of the terminal cover 2 to the cabinet door 1. At the same time, the terminal cover 2 covers and protects the terminals. At this time, the rotating buckle 31 is in the locked position and the terminal cover 2 is in the position as shown in the picture. Figure 1 The shown is the cover position.
[0029] By rotating the rotating buckle 31, the rotating buckle 31 can be switched between a locked position engaged with the locking slot 32 and an unlocked position away from the locking slot 32. This allows the terminal cover 2 to switch between a covered position that covers the terminals on the cabinet door 1 and an open position that exposes the terminals on the cabinet door 1. Therefore, when it is necessary to maintain the terminals, the terminal cover 2 can be opened simply by unscrewing the rotating buckle 31. This avoids the need to use screws or welding as in the prior art to fix the terminal cover 2 and also improves the ease of operation for daily maintenance.
[0030] Of course, in other embodiments, the positions of the rotating buckle 31 and the snap-fit groove 32 can be interchanged, that is, the rotating buckle 31 is assembled on the terminal cover 2 and the snap-fit groove 32 is set on the cabinet door 1, so that the terminal cover 2 can also be locked or opened.
[0031] In another preferred embodiment, such as Figure 2 As shown, an elastic element 4 is provided between the rotating buckle 31 and the cabinet door 1. The elastic element 4 uses its own elasticity to restrict the buckle part 311 within the snap-fit groove 32.
[0032] More specifically, the elastic element 4 is an elastic EVA cushioning layer, which is disposed on the inside of the cabinet door 1 facing the terminal cover 2. Of course, in other embodiments, the elastic element 4 can also be a torsion spring structure.
[0033] When the terminal cover 2 is locked, the terminal cover 2 elastically presses against the EVA buffer cotton layer, and the EVA buffer cotton layer forms a rebound force to restrict it. This ensures that the terminal cover 2 elastically presses against the buckle part 311, thereby restricting the buckle part 311 in the snap-fit groove 32, thus ensuring that the terminal cover 2 is securely locked to the cabinet door 1.
[0034] In another preferred embodiment, the terminal cover 2 is a box structure with a one-way opening and is generally square, so that during routine maintenance, the terminal cover 2 can be opened and rotated downwards by 90°, at which time the opening of the terminal cover 2 faces upwards, and easily lost screws or tools can be placed inside.
[0035] Further preferred, such as Figure 1 and Figure 3 As shown, the terminal cover 2 is provided with two elastic plugs 21 for buffering at the lower end away from the snap-fit groove 32. Specifically, the elastic plugs 21 are silicone plugs.
[0036] like Figure 3 As shown, when the terminal cover 2 is rotated 90° to the open position, the terminal cover 2 and the cabinet door 1 form a 90° angle with each other, and the terminal cover 2 abuts against the cabinet door 1 through the silicone plug. This avoids the terminal cover 2 directly colliding with the cabinet door 1 while achieving shock absorption. Of course, in other embodiments, the elastic plug 21 can also be a rubber plug or other plastic plugs.
[0037] Further preferred, such as Figure 3 As shown, a damping fit is formed between the rotating connector 5 and the terminal cover 2 to reduce the rotational speed of the terminal cover 2 during unlocking. That is, after the terminal cover 2 is unlocked, the terminal cover 2 will rotate downwards. During the rotation, the damping effect ensures that it will not flip down quickly, thus reducing the impact force on the terminal cover 2.
[0038] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
