Description

Technical Field

[0001] This utility model relates to the field of charging piles, and in particular to a power distribution device, main cabinet and charging system. Background Technology

[0002] With the popularization of new energy vehicles, the charging systems used in electric vehicles are becoming increasingly common, and correspondingly, the demand for maintenance and repair of these charging systems is also increasing. The aforementioned charging system mainly consists of two parts: charging piles and power distribution cabinets. The power distribution cabinet includes a cabinet body and a power distribution device installed inside the cabinet. The power distribution device includes a mounting plate and numerous power distribution modules fixed to the mounting plate. Because the installation of the power distribution modules on the mounting plate uses a large number of fasteners, each disassembly and reassembly of the power distribution modules involves the removal and installation of a large number of fasteners, which is very time-consuming and labor-intensive. Utility Model Content

[0003] Therefore, it is necessary to provide a power distribution device, main cabinet, and charging system to address the problem of time-consuming and labor-intensive maintenance and replacement of power distribution modules.

[0004] A power distribution device includes a bracket and a power distribution module; the bracket includes a mounting plate and a first support plate, a groove is provided on a first surface of the mounting plate, the first support plate is fixed on the mounting plate and located at the end of the groove, the power distribution module is supported on the first support plate, and the power distribution module is slidably disposed at the groove.

[0005] In one embodiment, one of the power distribution module and the first support plate is provided with a positioning hole, and the other is provided with a positioning pin. The positioning pin extends axially along the slide groove and is inserted into the positioning hole.

[0006] In one embodiment, the bracket further includes a first locking plate fixed to a second surface of the mounting plate. One of the first locking plate and the power distribution module is provided with a first locking hole, and the other is provided with a first locking screw, which engages with the first locking hole.

[0007] In one embodiment, there are at least two slides arranged side by side, with the power distribution module disposed at at least two of the slides. The power distribution device also includes a conductive strip, which is locked to the at least two power distribution modules by a second locking screw.

[0008] A main unit cabinet includes a cabinet body and the power distribution device, wherein the power distribution device is installed inside the cabinet body.

[0009] In one embodiment, a second support plate is fixed to the inner wall of the cabinet, and the bracket further includes a third support plate, which is fixed to the mounting plate and supported on the second support plate.

[0010] In one embodiment, the second support plate extends along the depth direction of the cabinet to allow the third support plate to move along the depth direction of the cabinet.

[0011] In one embodiment, the main unit cabinet further includes a power module, which is installed inside the cabinet and located above the power distribution device;

[0012] The main unit cabinet has a maintenance state and a working state. When the main unit cabinet is in the working state, the power distribution module is at least partially located within the projection of the power module on the axial direction of the slide rail. When the main unit cabinet is in the maintenance state, the power distribution module is located outside the projection of the power module on the axial direction of the slide rail.

[0013] In one embodiment, the bracket further includes a second locking plate, and a third locking plate is provided inside the cabinet. The second locking plate and the third locking plate are opposite each other in the depth direction of the cabinet. When the main unit cabinet is in working state, the second locking plate is attached to and locked onto the third locking plate.

[0014] A charging system includes a charging pile and a main unit cabinet, wherein the charging pile is electrically connected to the main unit cabinet.

[0015] The beneficial effects of this utility model are as follows:

[0016] When the power distribution device is working normally, the power distribution module can be supported and positioned by the first support plate, thus staying on the bracket. With the limiting effect of the sliding groove on the power distribution module, the number of fasteners required for the power distribution module on the bracket can be effectively reduced.

[0017] When a power distribution module malfunctions, it can be quickly removed from the bracket by pulling it upwards, allowing it to slide along a groove and detach from the support. Because the number of fasteners used in the power distribution module is reduced, the number of fasteners that need to be removed before pulling it upwards is also reduced. Consequently, the external space required for fastener removal is reduced. In some cases, the removal of the power distribution module can even be performed directly inside the cabinet, without needing to remove the entire power distribution unit from the cabinet beforehand. This further reduces the effort and time required for disassembly, improving the efficiency of power distribution module removal.

[0018] After the power distribution module is repaired, it can slide back into the slide groove from the end away from the first support plate, and then be supported on the first support plate again under the guidance of the slide groove, thereby realizing the rapid assembly of the power distribution module.

[0045] Example:

[0046] This embodiment provides a charging system, including a charging pile and a main unit cabinet, wherein the charging pile is electrically connected to the main unit cabinet. The main unit cabinet includes a cabinet body 3 and a power distribution device. The power distribution device includes a bracket 1 and a power distribution module 2, wherein the power distribution module 2 is mounted on the bracket 1 and installed inside the cabinet body 3 along with the bracket 1.

[0047] See details Figure 6 and Figure 8The bracket 1 includes a mounting plate 11 and a first support plate 12. The mounting plate 11 has a first surface and a second surface, wherein a groove 111 is provided on the first surface. As an alternative embodiment, at least two annular ribs are spaced apart on the first surface, and adjacent annular ribs surround the groove 111. The first support plate 12 is fixed to the mounting plate 11 and is also located at the end of the groove 111. Exemplarily, in this embodiment, the first support plate 12 is substantially perpendicular to the extending direction of the groove 111, and the edge of the first support plate 12 is fixed to the edge of the mounting plate 11.

[0048] Specifically, such as Figures 3-5 The shape of the power distribution module 2 is adapted to the shape of the slide groove 111, so the power distribution module 2 can be slidably disposed in the slide groove 111. Guided by the moving direction of the slide groove 111, the power distribution module 2 can contact or separate from the first support plate 12, and the slide groove 111 also serves to limit the movement of the power distribution module 2.

[0049] like Figure 1 and Figure 2 As shown, a second support plate 31 is fixed to the inner wall of cabinet 3, and the second support plate 31 is horizontally positioned. Figure 3 and Figure 4 As shown, the bracket 1 also includes a third support plate 15, which is fixed on the mounting plate 11 and is generally parallel to the first support plate 12.

[0050] See Figure 13 and Figure 14 Inside the cabinet 3, the third support plate 15 is horizontally positioned, allowing it to rest on and conform to the second support plate 31, thus suspending the entire power distribution device within the cabinet 3. Meanwhile, the slide 111 and mounting plate 11 are substantially perpendicular to the horizontal plane, and the first support plate 12 is substantially parallel to the horizontal plane. Therefore, the power distribution module 2 can be supported on the first support plate 12 and positioned to allow it to operate normally on the bracket 1.

[0051] It is easy to understand that to prevent the power distribution module 2 from falling off the bracket 1, it may be necessary to lock it to the bracket 1 with fasteners. However, in this embodiment, based on the limiting effect of the slide groove 111 on the power distribution module 2 and the supporting effect of the first support plate 12 on the power distribution module 2, the number of fasteners required can be effectively reduced. Accordingly, when it is necessary to disassemble the power distribution module 2, the number of fasteners that need to be unlocked will also be reduced. In some other embodiments, by changing the cross-sectional shape of the slide groove 111, the limiting effect of the slide groove 111 on the power distribution module 2 is enhanced, and the power distribution module 2 can even remain stably on the bracket 1 without fasteners.

[0052] like Figure 9 As shown, typically there are at least two power distribution modules 2, which are arranged side by side on the bracket 1. Correspondingly, in this embodiment, there are at least two slides 111, which are arranged side by side on the first surface, and power distribution modules 2 are provided at at least two slides 111. Under normal working conditions, each slide 111 of the power distribution device is generally provided with a power distribution module 2.

[0053] In this embodiment, when a portion of the power distribution module 2 malfunctions, the fasteners on this portion of the power distribution module 2 are first unlocked. Then, the power distribution module 2 is pulled upwards, moving away from the first support plate 12 and separating from it until it detaches from the slide groove 111, thus disassembling the power distribution module 2 from the bracket 1. During this disassembly process, due to the small number of fasteners, the disassembly speed of the power distribution module 2 is faster and more efficient. After the power distribution module 2 is repaired, it can re-enter the slide groove 111 from the end away from the first support plate 12 and move along it. Based on the guiding effect of the slide groove 111, the power distribution module 2 can eventually be re-supported on the corresponding first support plate 12. Again, due to the small number of fasteners, the power distribution module 2 can be re-locked onto the bracket 1 more quickly.

[0054] like Figure 5 and Figure 8 As shown, in this embodiment, the power distribution module 2 is provided with a positioning hole 21, and the first support plate 12 is provided with a positioning pin 121, which extends axially along the slide groove 111. See also Figure 4 During the sliding process of the power distribution module 2 at the slide groove 111, the positioning pin 121 can be aligned and inserted into the positioning hole 21, thereby increasing the stability of the power distribution module 2 on the first support plate 12 and further reducing the use of fasteners.

[0055] In some other embodiments, the positioning hole 21 may be provided on the first support plate 12, and the positioning pin 121 may be provided on the power distribution module 2.

[0056] As a specific implementation of the fastener, in this embodiment it can be a first locking screw 22. For example... Figures 5-7 As shown, the first locking screw 22 is disposed on the power distribution module 2. The bracket 1 also includes a first locking plate 13, which is fixed to the second surface of the mounting plate 11. The first locking plate 13 is provided with a first locking hole 131. See details. Figure 9 and Figure 10 The first locking screw 22 engages with the first locking hole 131 to lock.

[0057] In some other embodiments, the first locking screw 22 may also be provided on the first locking plate 13, and the first locking hole 131 may be provided on the power distribution module 2.

[0058] Power distribution devices typically also include a conductive strip 14. See details. Figure 9 and Figure 10 The conductive strip 14 is locked to at least two power distribution modules 2 by a second locking screw 141. Figure 11 and Figure 12 As shown, when it is necessary to disassemble a partially faulty power distribution module 2, the first locking screw 22 and the second locking screw 141 on this part of the power distribution module 2 need to be unlocked simultaneously before it can be lifted up.

[0059] like Figure 15 and Figure 17 As shown, the main unit cabinet also includes a power module 4, which is installed inside the cabinet 3 and located above the power distribution device.

[0060] See you again Figure 2 and Figure 14 In this embodiment, the second support plate 31 extends along the depth direction of the cabinet 3, so the third support plate 15 and the power distribution device as a whole can move on the second support plate 31 along the depth direction of the cabinet 3. Thus, the main cabinet has a maintenance state and a working state.

[0061] See details Figure 17 and Figure 18 When the main unit cabinet is in operation, the power distribution device is relatively close to the inside of the cabinet 3. At this time, the power distribution module 2 is at least partially located within the projection of the power module 4 on the axial direction of the slide 111. Even if the first locking screw 22 and the second locking screw 141 are unlocked, the power distribution module 2 cannot be disengaged from the slide 111.

[0062] See details Figure 13 and Figure 14 When the main unit cabinet is under maintenance, the power distribution device is relatively close to the opening of cabinet 3. At this time, the power distribution module 2 is located outside the projection of the power module 4 along the axial direction of the slide rail 111. Further combining... Figure 15 and Figure 16 As long as the first locking screw 22 and the second locking screw 141 are unlocked, the sliding of the power distribution module 2 at the slide groove 111 will not be blocked by the power module 4. Therefore, the installation and removal of the power distribution module 2 can be completed inside the cabinet 3 without removing the entire power distribution device from the cabinet 3.

[0063] See you again Figure 6 and Figure 7In this embodiment, the bracket 1 further includes a second locking plate 16. The side edge of the mounting plate 11 extends in a direction away from the second surface to form a connecting plate 17. The connecting plate 17 is generally perpendicular to the horizontal plane. The edges of the third support plate 15 and the second locking plate 16 are both fixed to the edge of the connecting plate 17. In this embodiment, the third support plate 15, the second locking plate 16, and the connecting plate 17 are all perpendicular to each other. See again. Figure 2 A third locking plate 32 is installed inside the cabinet 3, and the third locking plate 32 is generally perpendicular to the depth direction of the cabinet 3. When the third support plate 15 is supported on the second support plate 31, the second locking plate 16 and the third locking plate 32 are opposite each other in the depth direction of the cabinet 3. When the main cabinet is in working condition, the second locking plate 16 is attached to and locked onto the third locking plate 32.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
