[0027] Please refer to Figure 1 and Figure 2 simultaneously, and now the power cabinet 001 and the battery swapping device 002 provided by the embodiments of the present application will be described.

[0028] The power cabinet 001 includes a cabinet body 110 and a housing 120.

[0029] A receiving cavity 111 for accommodating power components is provided inside the cabinet body 110. Specifically, a receiving cavity 111 is provided inside the cabinet body 110, and power components are suitable for being installed in the receiving cavity 111. The cabinet body 110 is disposed on the outer peripheral side of the power components inside it to protect the power components inside.

[0030] The power cabinet 001 provided by the present application can be applied to the battery swapping device 002. When the power cabinet 001 provided by the present application is applied to the battery swapping device 002, the power components can be charging components such as plugs and chargers or electrical devices such as circuit boards.

[0031] In some embodiments, the cabinet body 110 is a hollow shell-like structure, so as to form a receiving cavity 111 inside the cabinet body 110. There is a single receiving cavity 111. In other embodiments, there are multiple receiving cavities 111, and the multiple receiving cavities 111 are isolated from each other.

[0032] The housing 120 is provided with an inner cavity and has a first opening 121 and a second opening 122. The first opening 121 and the second opening 122 are arranged opposite to each other. The cabinet body 110 is arranged in the inner cavity and is located between the first opening 121 and the second opening 122.

[0033] As Figure 1 shown, the first opening 121 and the second opening 122 are arranged opposite to each other along the x direction in the figure, so that the housing 120 penetrates along the x direction in the figure. The cabinet body 110 is arranged between the first opening 121 and the second opening 122 and is fixedly connected to the inner wall of the housing 120. The cabinet body 110 can be opened towards the first opening 121 or the second opening 122 to communicate the receiving cavity 111 with the outside of the housing 120.

[0034] The housing 120 covers both sides of the cabinet body 110 along the y direction in the figure and both sides of the cabinet body 110 along the z direction in the figure, so as to protect the top and bottom of the cabinet body 110 and provide protection to the cabinet body 110 from the side along the z direction in the figure, preventing the power components inside the cabinet body 110 from being damaged due to impacts in the y direction and the z direction in the figure.

[0035] The beneficial effect of the power cabinet 001 provided by the present application is that: compared with the prior art, the power cabinet 001 provided by the present application is sleeved with a housing 120 on the outer peripheral side of the cabinet body 110, and the housing 120 is provided with a first opening 121 and a second opening 122 to communicate the cabinet body 110 with the outside of the housing 120. The cabinet body 110 is completely located inside the housing 120. The housing 120 provides protection to the cabinet body 110, thereby protecting the power components inside the cabinet body 110, so that the power cabinet 001 provided by the present application has the advantage of better protection effect on the internal electrical components.

[0036] In some embodiments provided by the present application, as Figure 2 shown, the housing 120 includes a top plate 123. The top plate 123 is arranged at the top of the housing 120, and there is a first set gap 125 between the top plate 123 and the cabinet body 110.

[0037] Specifically, the part of the housing 120 on one side of the top of the cabinet body 110 forms the top plate 123. The top plate 123 provides protection to the cabinet body 110 at the top of the cabinet body 110 to avoid damage to the power components inside it caused by impacts at the top.

[0038] Thus, when the power cabinet 001 provided in the present application receives an impact or shock from its top, the top plate 123 undergoes a certain amount of deformation to absorb the kinetic energy of the impact. There is a first set gap 125 between the top plate 123 and the top of the cabinet body 110 to avoid the deformation of the top plate 123 when the top plate 123 deforms.

[0039] Therefore, on the one hand, the top plate 123 can provide protection for the top of the cabinet body 110. On the other hand, the first set gap 125 between the top plate 123 and the top of the cabinet body 110 can prevent the cabinet body 110 from being damaged when the top plate 123 is damaged and undergoes severe deformation. Thus, the power cabinet 001 provided in the present application has the advantage of better protecting the internal power components.

[0040] In some embodiments provided in the present application, as Figure 2 shown, the housing 120 includes a bottom plate 124. The bottom plate 124 is provided at the bottom of the housing 120, and there is a second set gap 126 between the bottom plate 124 and the cabinet body 110.

[0041] Specifically, the part of the housing 120 located on one side of the bottom of the cabinet body 110 forms the bottom plate 124. The bottom plate 124 provides protection for the cabinet body 110 at the bottom of the cabinet body 110 to prevent the cabinet body 110 from being damaged due to an impact from the bottom, which may cause damage to the internal power components.

[0042] Thus, when the power cabinet 001 provided in the present application receives an impact or shock from its bottom, the bottom plate 124 undergoes a certain amount of deformation to absorb the kinetic energy of the impact. There is a second set gap 126 between the bottom plate 124 and the bottom of the cabinet body 110 to avoid the deformation of the bottom plate 124 when the bottom plate 124 deforms.

[0043] Therefore, on the one hand, the bottom plate 124 can provide protection for the bottom of the cabinet body 110. On the other hand, the second set gap 126 between the bottom plate 124 and the bottom of the cabinet body 110 can prevent the cabinet body 110 from being damaged when the bottom plate 124 is damaged and undergoes severe deformation. Thus, the power cabinet 001 provided in the present application has the advantage of better protecting the internal power components.

[0044] In addition, the second set gap 126 between the cabinet body 110 and the bottom plate 124 can raise the bottom of the cabinet body 110 by the second set gap 126 when the power cabinet 001 provided in the present application is installed on the ground to protect the bottom of the cabinet body 110 and prevent water from entering or damaging the bottom of the cabinet body 110. Thus, the power cabinet 001 provided in the present application has the advantage of better protecting the internal power components.

[0045] In some embodiments provided in the present application, as Figure 1 and Figure 2As shown, a support body 130 is provided inside the housing 120. A support body 130 is provided between the bottom plate 124 and the cabinet body 110, and the support body 130 supports between the bottom plate 124 and the cabinet body 110.

[0046] Specifically, the support body 130 is filled in the second set gap 126, transmits the gravity of the cabinet body 110 to the bottom plate 124, and transmits the reaction force of the bottom plate 124 to the bottom of the cabinet body 110 to support the bottom of the cabinet body 110.

[0047] Thus, on the one hand, the bottom of the cabinet body 110 is supported by the support body 130. On the other hand, when the bottom plate 124 deforms upward, the support body 130 has a buffering effect between the bottom plate 124 and the cabinet body 110 to avoid damage to the bottom of the cabinet body 110, so that the power cabinet 001 provided by the present application has the advantage of better protecting the internal power components.

[0048] In some embodiments provided by the present application, as Figure 1 and Figure 2 shown, the housing 120 includes side plates 127. The side plates 127 are provided between the top plate 123 and the bottom plate 124, and the cabinet body 110 is connected to the side plates 127.

[0049] As Figure 1 and Figure 2 shown, there are two side plates 127. The top plate 123, the bottom plate 124 and the two side plates 127 enclose to form the housing 120, and an inner cavity of the housing 120 is formed between the top plate 123, the bottom plate 124 and the two side plates 127.

[0050] Thus, the cabinet body 110 is connected to the side plates 127 to provide support for the cabinet body 110 on both sides of the cabinet body 110 along the y direction in the figure.

[0051] In some embodiments provided by the present application, as Figure 1 and Figure 2 shown, a cabinet door 112 is provided on at least one side of the cabinet body 110 facing the first opening 121 and the second opening 122.

[0052] Specifically, one or more cabinet doors 112 are provided on the cabinet body 110. The cabinet doors 112 are movably provided on the surface of the cabinet body 110. When the cabinet doors 112 are opened, the accommodation cavity 111 is communicated with the outside of the housing 120. When the cabinet doors 112 are closed, the accommodation cavity 111 is cut off from the outside of the housing 120 to protect the circuit components inside the cabinet body 110.

[0053] In some embodiments, the cabinet door 112 is only provided on one side of the cabinet body 110 facing the first opening 121 or the second opening 122, so as to facilitate opening the cabinet body 110 from one side of the power cabinet 001 provided by the present application along the x direction in the figure.

[0054] In some other embodiments, there are multiple cabinet doors 112. A part of the cabinet doors 112 are arranged on one side of the cabinet body 110 facing the first opening 121, and another part of the cabinet doors 112 are arranged on one side of the cabinet body 110 facing the second opening 122, so that the cabinet body 110 can be opened from both sides of the power cabinet 001 provided by the present application along the x direction in the figure.

[0055] In some embodiments provided by the present application, such as Figure 1 and Figure 2 As shown, there are multiple accommodating cavities 111 and multiple cabinet doors 112. The side of the multiple accommodating cavities 111 facing the first opening 121 has openings, and the multiple cabinet doors 112 are arranged corresponding to the openings one by one.

[0056] Specifically, a plurality of mutually isolated accommodating cavities 111 are provided inside the cabinet body 110. The multiple accommodating cavities 111 can respectively accommodate different power components, and prevent the power components in a single accommodating cavity 111 from affecting the power components in other accommodating cavities 111 when a failure occurs, so that the power cabinet 001 provided by the present application has the advantage of better protection effect on the internal power components.

[0057] Therefore, the openings of the multiple accommodating cavities 111 are all arranged on the side of the cabinet body 110 facing the first opening 121, and the multiple accommodating cavities 111 are respectively provided with cabinet doors 112, so that the operator can open the cabinet doors 112 corresponding to the multiple accommodating cavities 111 and operate the power components in the multiple accommodating cavities 111 on the same side of the cabinet body 110.

[0058] In some embodiments provided by the present application, the multiple cabinet doors 112 include a first cabinet door 112 (not shown in the figure) and a second cabinet door 112 (not shown in the figure). The first cabinet door 112 is located on the side of the cabinet body 110 facing the first opening 121, and the second cabinet door 112 is located on the side of the cabinet body 110 facing the second opening 122.

[0059] Specifically, both the first cabinet door 112 and the second cabinet door 112 are opened on the surface of the cabinet body 110. The first cabinet door 112 is arranged on the side of the cabinet body 110 facing the first opening 121, and the second cabinet door 112 is arranged on the side of the cabinet body 110 facing the second opening 122.

[0060] In some embodiments, both the first cabinet door 112 and the second cabinet door 112 communicate with the same accommodating cavity 111, so that the operator can open the accommodating cavity 111 and operate the power components in the accommodating cavity 111 from both sides of the cabinet body 110 along the x direction in the figure; in some other embodiments, the first cabinet door 112 and the second cabinet door 112 are connected to different accommodating cavities 111, on the one hand, facilitating the operator to open different accommodating cavities 111 from both sides of the cabinet body 110 along the x direction in the figure respectively.

[0061] In some embodiments provided by the present application, such asFigure 2 As shown, the cabinet body 110 is provided with an avoidance groove, the notch of the avoidance groove faces the first opening 121, and a plurality of cabinet doors 112 are arranged at the bottom of the avoidance groove.

[0062] Specifically, the avoidance groove is arranged on one side of the cabinet body 110 facing the first opening 121, and the bottom of the avoidance groove is concave toward the inner side of the cabinet body 110, so that the notch of the avoidance groove faces the first opening 121, and a plurality of cabinet doors 112 are all arranged at the bottom of the avoidance groove.

[0063] Thus, a plurality of cabinet doors 112 are all arranged at the bottom of the avoidance groove, which can increase the gap between the cabinet doors 112 and the first opening 121 in the x direction in the figure. When the power cabinet 001 provided in the present application is damaged along the x direction in the figure, the protection effect on the plurality of cabinet doors 112 is increased, so that the power cabinet 001 provided in the present application has the advantage of better protecting the internal power components.

[0064] In a second aspect, the present application also proposes a power swapping device 002, and the power swapping device 002 includes the power cabinet 001 in any of the above embodiments.

[0065] Specifically, the power swapping device 002 adopts the power cabinet 001 described in any of the above embodiments. The power cabinet 001 provided in the present application has the advantage of better protecting the internal power components. Therefore, when the power swapping device 002 provided in the present application is arranged in an outdoor area, the power cabinet 001 provided in the present application can better protect the internal power swapping device 002.

[0066] In some embodiments provided in the present application, as Figure 3 shown, the power swapping device 002 includes a control component (not shown in the figure) and a charging component 210. The control component and the charging component 210 are both arranged in the cabinet body 110. The control component is electrically connected to the charging component 210, and the control component is located on one side of the charging component 210 facing the top of the cabinet body 110 of the power cabinet 001.

[0067] Specifically, a plurality of mutually isolated accommodation cavities 111 are arranged in the cabinet body 110. The control component and the charging component 210 are arranged in different accommodation cavities 111, and the accommodation cavity 111 where the control component is located is located above the accommodation cavity 111 where the charging component 210 is located.

[0068] The charging component 210 is used to charge the batteries 220 in different accommodation cavities 111. The user can take out the battery 220 fully charged by the charging component 210 in the accommodation cavity 111 and put in a battery 220 with insufficient power for the charging component 210 to charge, completing the power swapping operation. Compared with charging electrical equipment such as electric bicycles, the power swapping method has a higher replenishment efficiency for replenishing electrical energy.

[0069] The control component includes power components such as a circuit board. The control component is connected between an external circuit and multiple charging components 210. By detecting whether each charging component 210 is connected to a power-deficient battery 220 and controlling the on / off of the charging component 210, the cost of the control component is relatively high compared to the cost of the charging component 210.

[0070] Therefore, the accommodation cavity 111 where the control component is located is on the upper side of the accommodation cavity 111 where the charging component 210 is located. When the battery swapping device 002 provided in this application encounters water immersion or damage from the x direction in the figure, the probability of the control component being damaged is lower than the probability of the charging component 210 being damaged, thereby realizing the protection of the high-value part of the internal circuit components of the cabinet body 110.

[0071] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the protection scope of this application.
