[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0030] In order to solve the problem that in the prior art, the power distribution device is not convenient to be improved and the application is expanded along with product iteration, which is likely to cause waste of resources, the present utility model provides a power distribution device. Referring to Figures 1 to 6 , the power distribution device includes a box body 1, a power distribution component 4 and an adapter board 3. A fixing part is provided on the inner wall of the box body 1. The adapter board 3 is detachably connected to the box body 1 through the fixing part. Assembly parts are respectively provided at multiple different positions on the adapter board 3. The power distribution component 4 is detachably connected to the adapter board 3 through the assembly parts. In order to enable the power distribution device to set an adapter board 3 in the box body 1 to be replaced according to requirements when the internal space of the box body 1 of the power distribution box is sufficient for the product to which it is applied, different power distribution components 4 can be carried on the adapter board 3 according to requirements. A fixing part is provided on the inner part of the box body 1 to Figure 3 and Figure 4 take... as an example. The so-called fixing part refers to a plurality of fixing columns 12 on the bottom surface 11 of the box body 1. The adapter board 3 is connected to the box body 1 through the plurality of fixing columns 12. Assembly parts are provided on the adapter board 3. Take Figure 5 as an example. The so-called assembly part refers to a plurality of assembly columns 31 on the adapter board 3. The power distribution component 4 is connected to the adapter board 3 through the plurality of assembly columns 31. By providing the fixing part and the assembly part, the power distribution component 4 and the adapter board 3, and the adapter board 3 and the box body 1 can be disassembled multiple times, protecting the main structures of the adapter board 3 and the box body 1, making the power distribution device more durable. Further, it also makes the power distribution device easier to recycle and reuse, reducing waste of resources.

[0031] Compared with the prior art, in the technical solution of the present utility model, by providing a fixing portion on the inner wall surface of the box body 1 of the power distribution device, the detachable connection between the adapter plate 3 and the box body 1 is realized through the fixing portion. Assembly portions are respectively provided at multiple different positions on the adapter plate 3, and the detachable connection between the power distribution component 4 and the adapter plate 3 is realized through the assembly portions. The assembly portions at different positions can be adapted to the assembly pairs of different types of power distribution components 4, so that the adapter plate 3 can be assembled with different types of power distribution components 4 and can be replaced according to different requirements, thereby enabling the power distribution device to be improved and its application extended along with the product iteration, reducing waste of resources.

[0032] In one embodiment, referring to Figure 1 and Figure 5 ,the assembly portion includes an assembly post 31, and an assembly hole 311 is provided on the assembly post 31. The assembly hole 311 is used to connect and fix the power distribution component 4 through a fastener. In order to provide a good heat dissipation environment for the power distribution component 4 on the adapter plate 3, a plurality of assembly posts 31 are provided on the adapter plate 3. After the power distribution component 4 is installed on the assembly posts 31, there is a certain gap between the power distribution component 4 and the adapter plate 3. At this time, air flow can pass through this gap, which is beneficial to the heat dissipation of the power distribution component 4 during operation. In order to facilitate the use of standard fasteners, such as screws, rivets or pins, to fix the power distribution component 4 and the adapter plate 3, the assembly hole 311 is provided on the assembly post 31.

[0033] In one embodiment, referring to Figure 3 and Figure 4 ,the fixing portion includes a plurality of fixing posts 12, and a first fixing hole 121 is provided on the fixing post 12. A plurality of second fixing holes 33 are provided on the adapter plate 3. When the first fixing hole 121 and the second fixing hole 33 are connected in alignment through a fastener, the adapter plate 3 is fixed to the box body 1. A plurality of fixing posts 12 are provided in the box body 1, and the first fixing hole 121 is opened on the fixing post 12. At the same time, a plurality of second fixing holes 33 are opened on the adapter plate 3. The adapter plate 3 and the box body 1 are fixed by passing a fastener through the second fixing hole 33 and fixing it in the first fixing hole 121. By providing a plurality of first fixing posts 12, there are a plurality of connection points between the adapter plate 3 and the box body 1. When the power distribution device is in an environment with large vibrations, the plurality of connection points can ensure the stable connection between the adapter plate 3 and the box body 1. The provision of the first fixing hole 121 and the second fixing hole 33 facilitates the use of standard fasteners, such as screws, rivets or pins, to fix the box body 1 and the adapter plate 3.

[0034] Further, when the box body 1 is made of plastic material, standard parts in plastic mold manufacturing can be used to form the fixing post 12. In sheet metal, the fixing post 12 can also be directly riveted to the sheet metal surface through standard parts. Therefore, using the cylindrical fixing post 12 helps to reduce the manufacturing cost. The adapter plate 3 is assembled on the fixing post 12, and various power distribution components 4 can be assembled on the adapter plate 3 according to requirements. The adapter plate 3 provides a bearing function for the power distribution components 4, enabling the power distribution components 4 to have a stable working environment.

[0035] In an embodiment, referring to Figures 1 to 6 , a docking surface 110 is provided on the inner wall of the box body 1. An outlet hole 14 and a flow blocking convex portion 141 are provided on the docking surface 110. The flow blocking convex portion 141 surrounds the outlet hole 14 on the docking surface 110. The outlet hole 14 is used to make the inside of the box body 1 communicate with the outside space located behind the docking surface 110. Under the prior art, the condensation and dew in the power distribution device will slide down or directly drip along the inner wall of the power distribution box, and then flow into other devices 5 through the connection channel between the inside and outside of the power distribution device, causing potential problems in electrical safety. The docking surface 110 refers to the surface inside the box that is connected and docked with other components or the external environment. An outlet hole 14 for communicating with the outside space is opened on this surface, so as to Figure 1 , Figure 3 and Figure 4For example, the docking surface 110 coincides with the bottom surface 11. The outer side of the box body 1 opposite to the bottom surface 11 is connected to other devices 5. At this time, the bottom surface 11 is the docking surface 110. The condensed water in the distribution box will flow to the lowest position of the distribution box under the action of gravity due to free flow or vibration. In some cases, when the docking surface 110 is in a vertical state after installation, the condensed liquid will flow through the wire outlet hole 14, and then slide along the edge of the wire outlet hole 14 to the hole wall of the wire outlet hole 14 under the action of liquid tension and continue to slide down. At this time, some condensed water will flow out of the distribution box. In other cases, the docking surface 110 is on the bottom surface 11 of the distribution box. When the condensed water flows down and accumulates on the bottom surface 11, when the position of the environment where the distribution box is located changes, for example, when the distribution box is used in a vehicle or in a device with strong vibration, the condensed water will flow out of the wire outlet hole 14 to the outside of the distribution box and continue to flow to a lower position. The flow blocking convex portion 141 is a convex structure protruding from the docking surface 110 and can block the flow of the condensed liquid. The flow blocking convex portion 141 surrounds the wire outlet hole 14. When the transfer surface is in a vertical state, the flow blocking convex portion 141 can guide the condensed water around the wire outlet hole 14 so that it will not flow out of the box body 1. When the transfer surface is on the bottom surface 11 of the box body 1, the flow blocking convex portion 141 can block the condensed liquid from flowing into the wire outlet hole 14 so that it will not flow out of the box body 1. Compared with the prior art, the distribution device sets the docking surface 110 on the inner wall surface of the box body 1 and surrounds the flow blocking convex portion 141 around the wire outlet hole 14 for forming a space connection with the outside of the box body 1 back to the docking surface 110, so that the condensed liquid droplets will be blocked from flowing and will not flow into the wire outlet hole 14, avoiding potential electrical safety hazards.

[0036] In one embodiment, referring to Figure 3 and Figure 4 , the docking surface 110 is arranged on one side of the box body 1 away from the box cover 2, the wire outlet hole 14 is arranged close to the edge of the docking surface 110, and the flow blocking convex portion 141 is convexly formed along the edge of the wire outlet hole 14. For a distribution box with an open top, in order to facilitate the arrangement of the distribution components 4, generally, the docking surface 110 is considered to be arranged on the bottom surface 11 of the box body 1, which is more convenient for installation. After installing the distribution components 4, in order to electrically connect the distribution components 4 and other devices 5 installed in the space behind the docking surface 110, wires need to be connected through the wire outlet hole 14. In order to avoid structural interference between the distribution components 4 and the wire routing, the wire outlet hole 14 is arranged at the edge portion of the docking surface 110. At the same time, in order to make the flow blocking effect of the flow blocking convex portion 141 optimal, the flow blocking convex portion 141 is directly formed on the edge of the wire outlet hole 14, which can enhance the flow blocking effect while strengthening the structural strength of the wire outlet hole 14 and making it more durable.

[0037] Further, referring to Figure 3 and Figure 4, the docking surface 110 is a rectangular surface, and a plurality of the wire outlet holes 14 and the flow blocking protrusions 141 are arranged near the corners of the docking surface 110. The flow blocking protrusion 141 is in a circular ring shape, and the flow blocking protrusion 141 is concentrically arranged with the wire outlet hole 14. In order to facilitate the manufacture of the power distribution device and the arrangement of the power distribution component 4, a rectangular power distribution box is often used. At this time, the internal docking surface 110 is rectangular. In order to facilitate a more reasonable wire routing path and easier wire routing classification between the connection of the power distribution component 4 and other devices 5, a plurality of wire outlet holes 14 are arranged at the corners of the rectangular docking surface 110, which will neither affect the arrangement and installation of the power distribution component 4 nor help to strengthen the structure of the docking surface 110. The flow blocking protrusion 141 is arranged as a circular ring concentric with the wire outlet hole 14, which is convenient for one-time molding when manufacturing the power distribution box, especially when using a plastic material, and can effectively reduce the manufacturing cost. At the same time, the outer peripheral side of the circular ring-shaped flow blocking protrusion 141 is a curved surface, which is less likely to allow condensed water droplets to adhere through liquid surface tension compared to a flat surface, thereby further reducing the risk of condensed water leaking into the wire outlet hole 14.

[0038] In one embodiment, referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , a fixing portion is provided on the docking surface 110, and the height of the connecting protrusion is higher than the height of the flow blocking protrusion 141. In actual use, it is found that when the bottom surface 11 and the docking surface 110 are both on the inner surface of the same box body 1, even if an avoidance corner portion 35 is provided on the adapter plate 3 to avoid the structural interference between the adapter plate 3 and the flow blocking protrusion 141, there is still a situation where a wire is clamped between the adapter plate 3 and the flow blocking protrusion 141 during the assembly of the power distribution device, resulting in damage to the wire skin and posing a potential electrical safety hazard. Therefore, when the bottom surface 11 and the docking surface 110 are arranged on the same surface, the height of the connecting protrusion, that is, the fixing column 12, needs to be set higher than the flow blocking protrusion 141 so that there is a certain gap between the lower surface of the adapter plate 3 and the flow blocking protrusion 141 after the adapter plate 3 is installed, preventing serious damage to the wire skin under pressure when the wire is clamped and reducing the occurrence of potential electrical safety hazards.

[0039] In one embodiment, referring to Figures 1 to 3, a plurality of first alignment members are provided at the joint of the box body 1 and the box cover 2, and second alignment members are provided at the joint of the box cover 2 and the box body 1. When the box cover 2 is joined with the box body 1, the first alignment members and the second alignment members are aligned and fitted with each other. In actual use, it is found that it is not easy to align and install the box body 1 and the box cover 2. Especially for the box body 1 with a waterproof sealing strip provided at the joint of the box body 1 and the box cover 2, that is, the cover connection port 13, due to the certain elasticity of the waterproof sealing strip, the position of the box cover 2 and the box body 1 often deviates due to the resilience of the sealing strip after the box cover 2 is pressed thereon. Therefore, a first positioning member, i.e., a positioning post 15, is provided at the position of the docking interface, and a second positioning member, i.e., a positioning hole 22, is provided on the box cover 2 to position the box cover 2 and the box body 1. The positioning post 15 and the positioning hole 22 are aligned and fitted with each other. In order to make the alignment and positioning of the box cover 2 and the box body 1 more stable, generally more than two groups of positioning posts 15 and positioning holes 22 are provided. In particular, the positioning hole 22 provided on the box cover 2 is recessed from the joint surface of the box cover 2 and the box body 1 into the box cover 2. For the flat box cover 2, the positioning hole 22 can also facilitate distinguishing the front and back sides of the box cover 2 during the assembly process of the power distribution device, preventing installation errors.

[0040] In one embodiment, referring to Figure 2 and Figure 3 , at least one first plug boss 16 and / or at least one second plug boss 17 are provided on at least one outer wall of the box body 1. A first plug hole 161 for plugging a large-current connector is provided on the first plug boss 16, and a second plug hole 171 for plugging a small-current connector is provided on the second plug boss 17. The first plug hole 161 is configured to plug a large-current connector, and the second plug hole 171 is configured to plug a small-current connector. In actual use, in order to ensure that various voltage circuits do not connect wrongly to cause equipment damage, usually a specific type of terminal is provided for a specific voltage circuit or a specific function circuit to prevent wrong connection. Therefore, for a power distribution device, it is also necessary to have corresponding areas for installing various types. Figure 3For example, three types of plug-in bosses are provided on the outer wall of the box body 1 of the distribution box, a first plug-in hole 161 is provided on the first plug-in boss 16, a second plug-in hole 171 is provided on the second plug-in boss 17, and a third plug-in hole 181 is provided on the third plug-in boss 18. Among them, the first plug-in hole 161 is used to plug in the first connector 61, the second plug-in hole 171 is used to plug in the second connector 62, and the third plug-in hole 181 is used to plug in the third connector 63. Each connector is configured with a different circuit type and is configured on the wall surface of the outer side wall of the box body 1 according to the actual required quantity and the position of the connection end on the distribution component 4 located in the box body 1 of the distribution box. The purpose of providing the plug-in boss is to give the installation area of the connector a stronger structural strength to make the installation more stable. At the same time, because some connectors have snap-on designs or require screw fixation, the side walls of the box body 1 to be installed must be thick enough for correct installation. In order to save materials for manufacturing the distribution box body 1 and optimize costs, plug-in bosses of different sizes are set on the wall surface of the outer wall of the box body 1 for different connectors. In actual use, for power distribution devices in equipment with strong vibrations, a metal sheet with a hole of the same size as the corresponding plug-in hole (not shown in the figure) will be embedded in the position of the connector on the inner wall of the box body 1 to prevent excessive friction between the connector and the box body 1 due to vibration, which will cause the plug-in hole to wear and become larger, causing the connector to loosen and fall. In some cases, the above-mentioned metal sheet will also be connected to the ground wire to reduce electrostatic interference in the plastic box body.

[0041] Further, refer to Figures 1 to 4 The box body 1 is a rectangular box, with a cover opening 13 formed on one side of the box body 1. A plurality of plug-in bosses are provided on the outer wall adjacent to the cover opening 13. For the rectangular box body 1, a docking surface 110 is provided on the inner bottom surface 11 of the box body 1 to prevent interference between the adapter board 3 on which the power distribution assembly 4 is mounted and the plug-in components installed on the box body 1 and to facilitate installation of the adapter board 3 and the plug-in components.

[0042] In one embodiment, referring to Figure 1 、 Figure 4 and Figure 6 The box body 1 is provided with a plurality of first mounting holes 131, and the box cover 2 is provided with a plurality of second mounting holes 21. When the plurality of first alignment members are docked with the second alignment members, the first mounting holes 131 and the second mounting holes 21 are aligned with each other.

[0043] The cover surface is provided with a plurality of first mounting holes 131, and the lid 2 is provided with a plurality of second mounting holes 21. When the plurality of first aligning members are mated and engaged with the second aligning members, the fixing members pass through the mounting holes and connect with the second fixing holes 33. To ensure a secure connection between the lid 2 and the box body 1, a waterproof component is provided at the cover opening 13 to enhance the waterproof structure. Multiple first mounting holes 131 are provided on the cover surface, and multiple second mounting holes 21 are provided on the lid 2. After the positioning posts 15 and positioning holes 22 are provided, the positioning effect generated by the interlocking of the two makes it easier to secure the first mounting holes 131 and the second mounting holes 21 with fixing members such as rivets, bolts, or latches, thereby reducing the difficulty of installing the connecting members installed in the first mounting holes 131 and the second mounting holes 21. After the fixing members are installed in the first mounting holes 131 and the second mounting holes 21, the lid 2 and the box body 1 are pressed together by the fixing members. The waterproof component provided on the cover opening 13, under the action of the upper and lower pressure, effectively prevents the passage of liquids.

[0044] In one embodiment, referring to Figure 3 and Figure 4 A plurality of docking mounting holes 19 are also provided around the outer bottom end of the box body 1, and fixing parts are passed through the docking mounting holes 19 to connect and fix with other devices 5, so that the positional relationship between the power distribution device and other devices 5 is more fixed, thereby facilitating the arrangement of the lines and improving the stability of the overall equipment structure.

[0045] In one embodiment, referring to Figure 5 The adapter plate 3 is also provided with a leakage hole 34, which is used to drain condensed water dripping onto the adapter plate 3. When condensed water drips onto the adapter plate 3, in order to ensure a safer working environment for the power distribution assembly 4 and prevent electrical accidents, the condensed water needs to be drained away as quickly as possible. Therefore, the leakage hole 34 is provided to provide a channel for the condensed water to drip downwards into the adapter plate 3.

[0046] The present utility model also provides a charger, which includes the above-mentioned power distribution device. The charger has the function of preventing condensed water from flowing into other devices 5 communicated therewith, and adopts a power distribution device with various optimized designs, including a rectangular box body, a cover connection port 13, various types of plug bosses, alignment members, fixing members, etc., ensuring the electrical connection stability and safety during the charging process. The positioning posts 15 provided in the power distribution device of the charger are butt-joined and fitted with the positioning holes 22, and the combination of multiple groups of first mounting holes 131 and second mounting holes 21 with the fixing members ensures that the charger is not prone to structural loosening problems during use. The charger also has a certain degree of sealing performance, which can effectively prevent dust and moisture from invading, improving the durability of the charger and enabling it to adapt to more severe environmental conditions. The charger also has a detachable adapter plate 3 for carrying the power distribution assembly 4, making the maintenance and repair of the charger more convenient. The charger is applicable to various use environments including charging stations, power distribution vehicles, industrial production lines, etc.
