[0001] This application relates to the field of energy storage technology, and in particular to a cover plate assembly and an energy storage distribution cabinet. Background Technology

[0002] In energy storage distribution cabinets, a control circuit board is typically required for power control. This control circuit board usually requires manual operation and also needs protection; therefore, it is typically installed in an openable housing. In related technologies, a removable cover assembly is usually installed on one surface of the housing. When manual operation of the control circuit board is needed, the cover assembly is removed; after operation, the cover assembly needs to be reinstalled on the housing, making the process complex. Utility Model Content

[0003] The main technical problem solved by the embodiments of this application is to provide a cover plate assembly and an energy storage distribution cabinet, which locks the cover assembly to the cover plate body by magnetic attraction, thereby improving the efficiency of opening or closing the cover assembly, thereby improving the work efficiency of operators, and reducing the risk of wear and tear, thus reducing the risk that the cover assembly cannot be locked to the cover plate body.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a cover plate assembly, including a cover plate body, a closing member, a sliding member, a first magnetic member, and a second magnetic member. The cover plate body is provided with a groove and a sliding groove. The closing member is rotatably disposed on the cover plate body. When the closing member is in a first position, the closing member closes the groove. The sliding member is slidably disposed in the sliding groove. The first magnetic member is disposed on the sliding member. The second magnetic member is disposed on the closing member. When the closing member is in the first position and the sliding member is in the second position, along the first direction, the projection of the first magnetic member and the projection of the second magnetic member at least partially overlap, and the first magnetic member and the second magnetic member are magnetically attracted to each other. When the sliding member is in the third position, along the first direction, the projection of the first magnetic member and the projection of the second magnetic member are offset from each other, and the attraction between the first magnetic member and the second magnetic member is smaller than that in the second position. The first direction is perpendicular to the cover plate body.

[0005] In some embodiments, the cover assembly includes a third magnetic element disposed on the cover member, and the first magnetic element and the third magnetic element repel each other; when the cover member is in a first position and the slider is in a second position, the attractive force between the first magnetic element and the second magnetic element is greater than the repulsive force between the first magnetic element and the third magnetic element; when the cover member is in the first position and the slider is in the second position, the repulsive force between the first magnetic element and the third magnetic element is greater than the attractive force between the first magnetic element and the second magnetic element.

[0006] In some embodiments, both the first magnetic element and the third magnetic element are magnets, and in a first direction, the polarity of the end of the first magnetic element near the third magnetic element is the same as the polarity of the end of the third magnetic element near the first magnetic element; and / or

[0007] Both the first and second magnetic components are magnets. In a first direction, the polarity of the end of the first magnetic component near the second magnetic component is opposite to the polarity of the end of the second magnetic component near the first magnetic component; and / or

[0008] The first magnetic component is a magnet, and the second magnetic component is an iron block.

[0009] In some embodiments, the cover assembly includes a mounting member fixed to the cover body, the mounting member and the cover body together enclosing a receiving space, at least a portion of the sliding member being received in the receiving space, and at least a portion of the sliding member being received in a groove.

[0010] In some embodiments, one of the mounting member and the sliding member is provided with a guide rail, and the other is provided with a guide groove, with the guide rail slidably disposed in the guide groove.

[0011] In some embodiments, the slider is provided with a support portion, the support portion is provided with a support groove, and the first magnetic element is at least partially housed in the support groove.

[0012] In some embodiments, the cover plate body is provided with a stepped portion, the stepped portion is located in the groove, and the stepped portion is connected to the side wall of the groove near the slide. A clearance groove is provided on the side of the stepped portion away from the groove, and at least a portion of the first magnetic element is received in the clearance groove. When the cover is in the first position, the cover abuts against the stepped portion, and along the first direction, at least a portion of the projection of the second magnetic element is located within the projection of the stepped portion.

[0013] In some embodiments, the cover assembly includes a fastener mounted on one end of the cover assembly, and a second magnetic element and a third magnetic element are both disposed on the fastener.

[0014] In some embodiments, the cover body is provided with at least one window communicating with a recess, the window being configured to allow a control element of the control circuit board to pass through, such that at least a portion of the control element is exposed to the recess.

[0015] To solve the above-mentioned technical problems, another technical solution adopted in the embodiments of this application is to provide an energy storage distribution cabinet, including a housing and the above-mentioned cover plate assembly.

[0016] The beneficial effects of this application embodiment are as follows: Unlike the prior art, in this application embodiment, by sliding the slider to the second position, the attraction between the first magnetic element and the second magnetic element can keep the cover in the first position, thereby keeping the cover in the groove and protecting the control element exposed in the groove. When it is necessary to open the cover, the slider can be slid to the third position, thereby reducing the attraction between the first magnetic element and the second magnetic element, making it convenient for the user to open the cover. The operation process is simple and convenient, and the risk of functional failure due to wear between the first magnetic element and the second magnetic element is small.

[0028] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "inner," "outer," "vertical," "horizontal," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0031] Energy storage distribution cabinets typically require a control circuit board to control the input or output of electrical energy. The control circuit board usually needs to be operated manually, and it is also necessary to avoid exposing the control circuit board to protect it. Therefore, the control circuit board needs to be installed in an openable housing. When manual operation is required, the cover assembly on the housing is opened to expose the control components of the control circuit board to the outside, thereby facilitating manual operation. After the operation is completed, the cover assembly is closed.

[0032] In related technologies, a detachable or openable cover assembly is typically installed on the housing. The first method uses detachable screws to fix the cover assembly. When manual operation of the control circuit board is required, the cover assembly is removed, and then tightened again with screws afterward. This method is cumbersome and inefficient. The second method uses a pivot to rotate the cover assembly, which is opened and locked via a handle and mechanical lock. This method requires the operator to use a key to open or close the mechanical lock. While more efficient than the first method, it requires the operator to carry the key, which is at risk of loss. The third method uses a pivot to allow the cover assembly to rotate, and the cover assembly is locked by latches. While this method further improves efficiency, the latches are prone to wear during use, leading to latch failure and ineffective locking of the cover assembly.

[0033] To address at least some of the shortcomings of the prior art, this application provides a cover assembly that magnetically locks the cover member to the cover body, thereby improving the efficiency of opening or closing the cover member, thus increasing the operator's work efficiency, and reducing the risk of wear and tear, thus reducing the risk that the cover member cannot be locked to the cover body.

[0034] The specific structure and function of this application are described below.

[0035] Please see Figure 1 and Figure 2 The cover plate assembly 100 includes a cover plate body 110, a cover fitting 120, a sliding member 130, a first magnetic member 140, and a second magnetic member 150. The cover plate body 110 is provided with a groove 111 and a sliding groove 112, the sliding groove 112 and the groove 111 being spaced apart from each other. The cover fitting 120 is rotatably disposed on the cover plate body 110, and when the cover fitting 120 is in a first position relative to the cover plate body 110, such as... Figure 1 As shown, the cover 120 covers the groove 111; when the cover 120 leaves the first position, as... Figure 3 As shown, at least a portion of the groove 111 is exposed to the outside. It is worth noting that the control elements mounted on the control circuit board (not shown) are exposed in the groove 111. Therefore, when the cover 120 is rotated to move it away from the first position, the control elements are exposed to the outside, facilitating operation by personnel to control the power input or output of the energy storage distribution cabinet 1000 via the control circuit board. A slider 130 is disposed in the slide groove 112, and the slider 130 can slide along the slide groove 112 between a second position and a third position. See also... Figure 2A first magnetic element 140 is disposed on the sliding member 130, and a second magnetic element 150 is disposed on the cover member 120. The second magnetic element 150 is configured to attract the first magnetic element 140. When the cover member 120 is in the first position and the sliding member 130 is in the second position, please refer to [reference needed]. Figure 1 and Figure 4 Along the first direction X, the projection of the first magnetic element 140 at least partially overlaps with the projection of the second magnetic element 150. Under the attraction between the first magnetic element 140 and the second magnetic element 150, the cover 120 can be held in the first position, thereby protecting the control element exposed in the groove 111. The first direction X is perpendicular to the cover body 110. When the slider 130 slides along the groove 112 to the third position, please refer to... Figure 5 and Figure 6 Along the first direction X, the projection of the first magnetic element 140 and the projection of the second magnetic element 150 are offset from each other. That is, in the second position, the distance between the first magnetic element 140 and the second magnetic element 150 is smaller than that in the third position. Therefore, as the slider 130 slides from the second position to the third position, the attraction between the first magnetic element 140 and the second magnetic element 150 gradually weakens, so that the user can easily open the cover 120 and then operate the control elements on the control circuit board. In this embodiment, by sliding the slider 130 to the second position, the attraction between the first magnetic element 140 and the second magnetic element 150 can hold the cover 120 in the first position, thereby keeping the cover 120 in the cover groove 111 and protecting the control element exposed in the groove 111. When it is necessary to open the cover 120, the slider 130 can be slid to the third position, thereby reducing the attraction between the first magnetic element 140 and the second magnetic element 150, making it convenient for the user to open the cover 120. The operation process is simple and convenient, and the risk of functional failure due to wear between the first magnetic element 140 and the second magnetic element 150 is small.

[0036] In some embodiments, please refer to Figure 2 and Figure 3 The cover body 110 is provided with at least one window 115, which communicates with the recess 111 and is located at the bottom of the recess 111. The window 115 is configured to allow the control elements of the control circuit board to pass through, so that at least a portion of the control elements can be exposed to the recess 111. Therefore, when the cover 120 is opened to expose the recess 111 to the outside, the user can operate these control elements and thus control the energy storage distribution cabinet 1000.

[0037] In some embodiments, please refer to Figure 2The cover plate body 110 is also provided with a rotating hole 113, which communicates with the side wall of the groove 111. The cover member 120 is provided with a rotating protrusion 121, which is rotatably disposed in the rotating hole 113 so that the cover member 120 can rotate around the rotating hole 113, thereby opening or closing the groove 111.

[0038] In some embodiments, please refer to Figure 2 and Figure 3 The cover assembly 100 includes a third magnetic element 160, which is fixed to the cover assembly 120. The third magnetic element 160 and a second magnetic element 150 are spaced apart along a second direction Y, which is approximately parallel to the direction in which the slider 130 slides along the groove 112. The first magnetic element 140 and the third magnetic element 160 are magnetically repelled. When the cover assembly 120 is in the first position and the slider 130 is in the second position, please refer to [reference needed]. Figure 1 and Figure 4 When the attractive force between the first magnetic element 140 and the second magnetic element 150 is greater than the repulsive force between the first magnetic element 140 and the third magnetic element 160, the cover 120 can remain in the first position, thereby maintaining the cover groove 111. When the slider 130 is slid from the second position to the third position, please refer to... Figure 5 and Figure 6 The repulsive force between the first magnetic element 140 and the third magnetic element 160 is greater than the attractive force between the first magnetic element 140 and the second magnetic element 150. At this time, under the action of the repulsive force between the first magnetic element 140 and the third magnetic element 160, the cover 120 is bounced away from the first position, thereby making it easier for the user to open the cover 120. Furthermore, since the repulsive force between the first magnetic element 140 and the third magnetic element 160 is greater than the attractive force between the first magnetic element 140 and the second magnetic element 150, the force required to open the cover 120 can be reduced.

[0039] It should also be noted that, please refer to Figure 1 When the cover 120 is in the first position, the surface of the cover 120 facing away from the groove 111 is approximately on the same plane as the first surface 116 of the cover body 110, and the gap between the edge of the cover 120 and the sidewall of the groove 111 is small, making it difficult for a user to insert their finger into the gap to open the cover 120. Therefore, in the embodiments of this application, please refer to... Figure 5 By setting a third magnetic element 160, when the slider 130 slides to the third position, the repulsive force between the first magnetic element 140 and the third magnetic element 160 is greater than the attractive force between the first magnetic element 140 and the second magnetic element 150, so that at least a part of the cover 120 can be popped out of the groove 111, thereby making it easier for the user to fully open the cover 120 and reducing the difficulty for the user to open the cover 120.

[0040] Further, please refer to Figure 1 and Figure 4 When the cover 120 is in the first position and the slider 130 is in the second position, along the first direction X, the projections of the first magnetic element 140 and the second magnetic element 150 at least partially overlap, and the projections of the first magnetic element 140 and the third magnetic element 160 are offset from each other. This results in the attractive force between the first magnetic element 140 and the second magnetic element 150 being greater than the repulsive force between the first magnetic element 140 and the third magnetic element 160, thereby keeping the cover 120 in the first position. When the cover 120 is in the first position and the slider 130 is in the third position, please refer to [link to relevant documentation]. Figure 5 and Figure 6 Along the first direction X, the projections of the first magnetic element 140 and the second magnetic element 150 are offset from each other, and the projections of the first magnetic element 140 and the third magnetic element 160 overlap at least partially, so that the repulsive force between the first magnetic element 140 and the third magnetic element 160 is greater than the attractive force between the first magnetic element 140 and the second magnetic element 150, thereby causing at least a portion of the cover 120 to be ejected outside the groove 111, making it convenient for the user to open the cover 120.

[0041] In some embodiments, the first magnetic element 140 is a magnet, and the second magnetic element 150 can be an iron block, so that the first magnetic element 140 and the second magnetic element 150 attract each other.

[0042] In some embodiments, the second magnetic element 150 may also be a magnet, and along the first direction X, the polarity of the end of the first magnetic element 140 near the second magnetic element 150 is opposite to the polarity of the second magnetic element 150 near the first magnetic element 140, thereby causing the first magnetic element 140 and the second magnetic element 150 to attract each other.

[0043] In some embodiments, the third magnetic element 160 is a magnet, and in the first direction X, the polarity of the end of the first magnetic element 140 near the third magnetic element 160 is the same as the polarity of the end of the third magnetic element 160 near the first magnetic element 140, thereby causing the first magnetic element 140 and the third magnetic element 160 to repel each other.

[0044] In some embodiments, please refer to Figure 2 and Figure 7The cover plate assembly 100 includes a mounting member 170, which is fixed to the cover plate body 110. The mounting member 170 and the cover plate body 110 together enclose a receiving space 180, which communicates with a slide groove 112. The cross-sectional area of ​​the receiving space 180 perpendicular to the first direction X is larger than the cross-sectional area of ​​the slide groove 112. At least a portion of the slider 130 is received in the receiving space 180. The cross-sectional area of ​​the portion of the slider 130 received in the receiving space 180 perpendicular to the first direction X is larger than the cross-sectional area of ​​the slide groove 112, thereby reducing the risk of the slider 130 disengaging from the slide groove 112 into the receiving space 180. Furthermore, at least a portion of the slider 130 is received in the slide groove 112, and this portion is used for user operation, allowing the slider 130 to slide between a second position and a third position.

[0045] In some embodiments, one of the mounting member 170 and the slider 130 is provided with a guide rail 171, and the other is provided with a guide groove 131. At least a portion of the guide rail 171 is received within the guide groove 131, and the guide rail 171 and the guide groove 131 are slidably engaged, thereby guiding the sliding direction of the slider 130. Specifically, both the guide rail 171 and the guide groove 131 extend along the second direction Y, so that the guide rail 171 and the guide groove 131 cooperate to guide the slider 130 to move back and forth between the second position and the third position along the second direction Y. In this embodiment, guiding the sliding direction of the slider 130 through the sliding engagement between the guide rail 171 and the guide groove 131 is beneficial to improving the smoothness of the slider 130 during the sliding process.

[0046] In some embodiments, the guide rail 171 is disposed on the surface of the mounting member 170 facing the slider 130, and the guide groove 131 is disposed on the surface of the slider 130 facing the mounting member 170. It is understood that, as not shown in the figures, the guide rail 171 may also be disposed on the surface of the slider 130 facing the mounting member 170, and the guide groove 131 may be disposed on the surface of the mounting member 170 facing the slider 130.

[0047] In some embodiments, please refer to Figure 3 and Figure 7The cover plate body 110 is provided with a stepped portion 114, and the stepped portion 114 is connected to the side wall of the groove 111 near the slide groove 112. A relief groove 1141 is provided on the side of the stepped portion 114 away from the groove 111, and at least a portion of the first magnetic member 140 is received in the relief groove 1141. When the cover member 120 is in the first position, the cover member 120 abuts against the stepped portion 114, and along the first direction X, the projections of the second magnetic member 150 and the third magnetic member 160 are at least partially located within the projection of the stepped portion 114. In this embodiment, by providing a step portion 114, and providing a relief groove 1141 on the side of the step portion 114 away from the groove 111, the first magnetic element 140 can extend into the relief groove 1141. When the cover member 120 is in the first position, the first magnetic element 140 can be located below the second magnetic element 150 or the third magnetic element 160, which helps to shorten the shortest distance between the first magnetic element 140 and the second magnetic element 150 or between the first magnetic element 140 and the third magnetic element 160. Therefore, when the sliding member 130 is in the second position, the attractive force between the first magnetic element 140 and the second magnetic element 150 can be increased. When the sliding member 130 is in the third position, the repulsive force between the first magnetic element 140 and the third magnetic element 160 can be increased.

[0048] In some embodiments, please refer to Figure 2 The sliding member 130 is provided with a support portion 132, at least a portion of which is received in the relief groove 1141. The support portion 132 is provided with a support groove 1321, at least a portion of which is received in the support groove 1321, so that when the sliding member 130 slides along the slide groove 112, it drives the first magnetic member 140 in the support groove 1321 to slide.

[0049] In some embodiments, please refer to Figure 2 and Figure 3 The cover plate assembly 100 includes a fixing member 190, which is installed on one end of the cover assembly 120 near the sliding member 130. The second magnetic member 150 and the third magnetic member 160 are both installed on the fixing member 190. The fixing member 190 is fixed to the cover assembly 120, thereby fixing the second magnetic member 150 and the third magnetic member 160 to the cover assembly 120.

[0050] In some embodiments, please refer to Figure 8 and Figure 9 The cover 120 is provided with two slots 122 that are opposite each other along the second direction Y. The fastener 190 is provided with two snap-fit ​​parts 191. The two snap-fit ​​parts 191 are located at opposite ends of the fastener 190 along the second direction Y. One snap-fit ​​part 191 snaps into one slot 122, thereby fixing the fastener 190 and the cover 120. The assembly between the cover 120 and the fastener 190 is simple and convenient.

[0051] In some embodiments, the fastener 190 is provided with a protrusion 192, one end of which is connected to the snap-fit ​​portion 191. The cover 120 is provided with a snap-fit ​​hole 123, which communicates with the snap-fit ​​groove 122. When the snap-fit ​​portion 191 is snapped into the snap-fit ​​groove 122, the protrusion 192 is snapped into the snap-fit ​​hole 123, thereby reducing the risk of the snap-fit ​​portion 191 disengaging from the snap-fit ​​groove 122 and improving the stability of the connection between the fastener 190 and the cover 120.

[0052] In some embodiments, the fastener 190 is provided with a first mounting groove 193 and a second mounting groove 194, the first mounting groove 193 and the second mounting groove 194 are distributed at intervals along the second direction Y, the second magnetic element 150 is engaged in the second mounting groove 194, and the third magnetic element 160 is engaged in the second mounting groove 194.

[0053] In this embodiment, by sliding the slider 130 to the second position, the attraction between the first magnetic element 140 and the second magnetic element 150 can hold the cover 120 in the first position, thereby keeping the cover 120 in the cover groove 111 and protecting the control element exposed in the groove 111. When it is necessary to open the cover 120, the slider 130 can be slid to the third position, thereby reducing the attraction between the first magnetic element 140 and the second magnetic element 150, making it convenient for the user to open the cover 120. The operation process is simple and convenient, and the risk of functional failure due to wear between the first magnetic element 140 and the second magnetic element 150 is small.

[0054] This application also provides an embodiment of an energy storage distribution cabinet 1000, please refer to [link / reference]. Figure 10 The energy storage distribution cabinet 1000 includes a housing 200 and the aforementioned cover assembly 100, which covers the housing 200. Please refer to... Figure 2 and Figure 3 The aforementioned control circuit board (not shown) is disposed inside the housing 200, and the control elements on the control circuit board are exposed in the groove 111 after passing through the window 115 on the cover body 110. Therefore, when the user opens the cover 120, these control elements can be exposed to the outside world, thereby controlling the operation of the control circuit board. For the specific structure and function of the cover assembly 100, please refer to the above embodiments, which will not be described in detail here.

[0055] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
