Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

And "inner" and "outer" refer to the outline of the device.

[0037] There are numerous electrical systems and electronic devices in a vehicle, such as engine control systems, lighting systems, infotainment systems, safety systems, etc. A high-voltage power distribution unit (PDU) is a device used to manage and distribute electrical power, responsible for distributing the power output by the vehicle's battery pack or generator to various systems and devices in a reasonable manner, ensuring that they receive a stable power supply. For example, a high-voltage power distribution unit can provide a large current power path for high-power demand starter motors, and also provide a stable small current supply for low-power sensors. In the related art, the shell strength of the high-voltage power distribution unit (PDU) is low, and when connecting the external electrical device to the connector of the high-voltage power distribution unit (PDU), the external electrical device has a force on the connector, which can easily cause the shell part where the connector is located to deform.

[0038] To solve the above problems, the present application provides a high-voltage power distribution unit, which will be described in detail Figure 1The high-voltage power distribution unit can include a connector 200 and a housing 300, the connector 200 is mounted on the housing 300, and the housing 300 can also be used to mount other related components of the high-voltage power distribution unit. The high-voltage power distribution unit is connected to the external electrical equipment through the connector 200. In some examples, the external electrical equipment can be a load, so that the battery pack can distribute power to the external electrical equipment through the high-voltage power distribution unit to ensure that they obtain a stable power supply. In some examples, the external electrical equipment can be an external power source, so that the external power source can charge the battery pack through the high-voltage power distribution unit.

[0039] Please refer to Figure 2 The high-voltage power distribution unit also includes an electrical assembly 100 mounted on the housing 300, the electrical assembly 100 is used to be electrically connected with the battery pack, and the connector 200 is electrically connected with the electrical assembly 100, so that the high-voltage power distribution unit can be connected with the external electrical equipment through the connector 200. In this way, the external electrical equipment and the battery pack are electrically connected, which can realize the distribution of the power output by the battery pack to the external electrical equipment or charging the battery pack through the external electrical equipment. In some examples, the high-voltage power distribution unit is arranged inside the vehicle, and the battery pack is arranged inside the vehicle. The battery pack can be arranged outside the high-voltage power distribution unit, for example, the battery pack can be arranged below the high-voltage power distribution unit, and the battery pack can also be arranged beside the high-voltage power distribution unit.

[0040] The housing 300 includes a box body 310 and a box cover 330, the electrical assembly 100 is mounted in the box body 310, and the box cover 330 is connected with the box body 310. The box cover 330 and the box body 310 can be connected in a screwing, clamping, welding or other manner. In some examples, the box cover 330 and the box body 310 can be provided with through holes, and the box cover 330 and the box body 310 can be fastened by bolts.

[0041] The connector 200 is mounted on the box cover 330, and the connector 200 is mainly used to ensure safe and reliable transmission of power, so it has good mechanical strength, environmental resistance and electrical performance. The connector 200 includes a first connecting part 260 and a second connecting part 210 connected with each other. In some examples, the first connecting part 260 and the second connecting part 210 can be oppositely arranged, the first connecting part 260 is connected with the electrical assembly 100, and the second connecting part 210 is connected with the external electrical equipment.

[0042] The box cover 330 can be provided with a mounting hole 331 for mounting the connector 200. The second connecting part 210 is located on the side of the box cover 330 away from the box body 310 and is used to connect with the external electrical equipment; the first connecting part 260 is arranged in the mounting hole and is connected with the electrical assembly 100;

[0043] The high-voltage power distribution unit further comprises a reinforcing member 400 installed on the shell 300 to reinforce the shell 300, and the reinforcing member 400 can be made of iron, copper, alloy, or the like. The reinforcing member can be installed on the periphery of the mounting hole 331. In these embodiments, by providing the reinforcing member 400, the deformation of the box cover 330 caused by the force when the connector is connected with the external electrical equipment can be prevented. In some examples, the reinforcing member 400 can be installed on the side of the box cover 330 away from the box body 310, and in some examples, the reinforcing member 400 can also be installed on the side of the box cover 330 facing the box body 310.

[0044] Specifically, the connector 200 is installed on the box cover 330, the second connecting portion 210 of the connector 200 is located on the side of the box cover 330 away from the box body, and is used to be connected with the external electrical equipment, and the first connecting portion 260 of the connector 200 penetrates through the mounting hole 331 and is connected with the electrical assembly 100. When the second connecting portion 210 of the connector is connected with the external electrical equipment, the external electrical equipment has a force acting on the second connecting portion 210 of the connector, and the force acting on the second connecting portion 210 is transmitted to the box cover 330, so that the box cover 330 is subjected to a force towards the side of the box body 310, and the box cover 330 is easily deformed and depressed towards the side of the box body. The mounting hole of the box cover 330 has low strength, stress concentration, and larger deformation amount, that is, the mounting hole 331 of the box cover 330 is more easily deformed. Since the reinforcing member is provided on the periphery of the mounting hole, the reinforcing member can reinforce the mounting hole 331 of the box cover 330, so that the mounting hole 331 is not easily deformed, and the box cover 330 is not easily deformed, thereby achieving the effect of reinforcing the box cover 330.

[0045] Please refer to Figure 2 and Figure 3 In some embodiments, the reinforcing member 400 can be fixed on the side of the box cover 330 facing the box body 310, so that the outside of the shell of the high-voltage power distribution unit is more neat, and the connection with the external electrical equipment is facilitated. The connector 200 further comprises a connecting member 230 and a first peripheral portion 250 fixedly connected with the second connecting portion 210, and in some examples, the second connecting portion 210 and the first peripheral portion 250 can be fixedly connected by welding or one-piece forming, so that the sealing between the second connecting portion 210 and the first peripheral portion 250 is good.

[0046] The first peripheral portion 250 can be annularly arranged at one end of the second connecting portion 210 close to the first connecting portion 260, at least part of the cover 330 is located between the reinforcing member 400 and the first peripheral portion 250, and the first peripheral portion is located at the side of the cover away from the box. The connecting member 230 is arranged through the first peripheral portion 250 and the cover 330 and connected to the reinforcing member 400. The connector 200 is connected to the cover 330 through the cooperation of the connecting member 230 and the reinforcing member 400. In these embodiments, the reinforcing member 400 also has the function of mounting the connector 200. In some examples, the first peripheral portion 250 is provided with a through hole, and the reinforcing member 400 can be provided with a blind hole in communication with the through hole. The connecting member 230 passes through the through hole of the first peripheral portion 250 and the blind hole of the reinforcing member 400 in sequence, and the connector 200 is connected to the cover 330 through the cooperation of the connecting member 230 and the reinforcing member 400. In some examples, the connecting member 230 and the reinforcing member 400 can be screwed, and the connecting member 230 can be a screw.

[0047] In these embodiments, the reinforcing member 400 is fixed to the cover 330, and the connecting member 230 is arranged through the first peripheral portion 250 and the cover 330 and connected to the reinforcing member 400. Because the reinforcing member 400 is fixed to the cover 330, the reinforcing member 400 and the cover 330 have a large friction force, which can keep the relative position of the connecting member and the cover unchanged, so that the force of the connecting member acting on the cover is small, and the cover is not easy to deform.

[0048] Please combine Figure 5 In some embodiments, the periphery of the end of the reinforcing member 400 towards the cover 330 is sealingly connected to the cover 330, so as to prevent water vapor from entering the gap between the reinforcing member 400 and the cover 330 from the periphery of the reinforcing member 400, and further prevent water vapor from entering the gap between the connecting member and the cover 330, prevent the reinforcing member 400 and the connecting member 230 from rusting, and improve the service life of the electrical components and the like in the shell. In some examples, the periphery of the end of the reinforcing member 400 towards the cover 330 is welded to the cover 330.

[0049] Please combine Figure 5 In some embodiments, the reinforcing member 400 can be configured as a plurality of reinforcing members, and one reinforcing member 400 is arranged on each of the opposite sides of the mounting hole 331 along the length direction of the cover 330, so as to further prevent the mounting hole 331 from deforming.

[0050] In some examples, please combine Figure 1 and Figure 5There are three mounting holes 331 and six reinforcing members 400. The mounting holes 331 have four rounded corners. The short axis of the mounting holes 331 extends in the same direction as the length of the cover 330, and the long axis of the mounting holes 331 extends perpendicular to the length of the cover 330. The six reinforcing members 400 are arranged along the length of the cover 330. The reinforcing members 400 can be strip-shaped, and their length direction is perpendicular to the length direction of the cover 330.

[0051] Please combine Figure 5 In some embodiments, the high-voltage power distribution unit further includes a frame 500, which is fixed inside the enclosure 310 to reinforce the enclosure 310. The frame 500 includes a first part 510, a second part 530, and a third part 550. The first part 510 is attached to the enclosure cover 330, the second part 530 is connected to the side of the enclosure 310 facing the enclosure cover 330, and the third part 550 is located between the first part 510 and the second part 530, with its opposite ends fixedly connected to the first part 510 and the second part 530, respectively. The first part 510, the second part 530, and the third part 550 reinforce the enclosure cover 330 and the enclosure 310. The arrangement direction of the enclosure cover 330 and the enclosure 310 is a first direction, and the first connecting portion 260 and the second connecting portion 210 of the connector 200 are arranged along the first direction. When external electrical equipment is connected to the high-voltage power distribution unit via connector 200, the external electrical equipment exerts pressure on connector 200 along the first direction, and also on enclosure 310 and cover 330 along the first direction, making enclosure 310 and cover 330 prone to deformation or even cracking along the first direction. The first part 510 of frame 500 is attached to cover 330, and the second part 530 is connected to the side of enclosure 310 facing cover 330. That is, the first part 510, second part 530, and third part 550 are arranged along the first direction, and along the first direction, the opposite ends of frame 500 are respectively connected to the two ends of housing 300. Therefore, along the first direction, frame 500 can strengthen housing 300, preventing enclosure 310 and cover 330 from easily deforming or cracking along the first direction. In some embodiments, the external electrical equipment and connector 200 are plugged in. In some embodiments, please refer to... Figure 4 The first direction is the vertical direction.

[0052] In some embodiments, the frame 500 can be welded together using U-shaped structural steel, because U-shaped steel is not easily deformed and has high strength, which gives the frame 500 greater strength and better reinforces the cover 330 and the box body 310.

[0053] In some embodiments, the frame 500 can be fixed around the box body 310 by welding, so that the connection between the frame 500 and the box body 310 is more closely connected, has good integrity, and is not easy to separate or fall off.

[0054] Please combine Figure 2 In some embodiments, the box cover 330 includes a main body part 333 and a surrounding part 335, the surrounding part 335 is annularly arranged on the side of the main body part 333, the main body part 333 protrudes towards the side of the box body 310 relative to the surrounding part 335, and abuts against the surface of the first part 510 close to the box cover 330, so that the first part 510 and the box cover 330 can be closely matched, and when the external electrical equipment is connected to the high-voltage power distribution unit through the connector 200, the first part 510 can share the pressure transmitted to the box cover 330 through the connector 200, so that the box body 310 and the box cover are not easy to deform.

[0055] The main body part 333 and the surrounding part 335 can be integrally formed. The box cover 330 can form the main body part 333 and the surrounding part 335 by a milling process. Milling is a material removal machining method that moves along the surface of the workpiece by a rotating multi-blade cutter (milling cutter) to cut off the excess material to achieve the required size and flatness. Milling can process planes, bevels, grooves and other shapes. In the related art, the box cover is often processed by sheet metal bending and other methods. Sheet metal bending is a forming process that fixes the metal plate on a mold and uses a press or other equipment to apply force to bend the metal plate at a predetermined angle. This process is often used to manufacture parts with specific angles or shapes, such as frames, housings, etc. Compared with the box cover formed by sheet metal bending and other methods in the related art, the main body part 333 and the surrounding part 335 are formed by the milling process in this application, so that the surface of the box cover has high smoothness, does not need additional polishing or finishing, reduces the subsequent processing procedures, and makes the strength of the box cover 330 greater and not easy to deform.

[0056] In some embodiments, the material of the box cover 330 can be high-strength steel, the main body part 333 and the surrounding part 335 are formed by the milling process, and the main body part 333 of the box cover 330 is welded with a reinforcing part. In these embodiments, the box cover 330 can be effectively prevented from deforming under stress.

[0057] Please combine Figure 2In some embodiments, the housing 310 has a second peripheral portion 311 circumferentially arranged on the side near the cover 330; the second peripheral portion 311 is disposed opposite to at least a portion of the surrounding portion 335; the housing 300 also includes a sealing member 340, which is sandwiched between the second peripheral portion 311 and the surrounding portion 335. The sealing member 340 seals the housing 310 and the cover 330, protecting the electrical components 100 and other structures inside the housing 300. The sealing member 340 can be made of an elastic material, such as rubber or silicone.

[0058] The cover 330 has a plurality of first through holes spaced apart around its circumferential portion 335, and the second periphery of the housing has a plurality of second through holes that mate with the first through holes. Fasteners such as bolts are used to pass through the first and second through holes to securely connect the cover 330 to the housing. A seal 340 is provided between the second periphery and the circumferential portion 335 to prevent moisture from entering the housing.

[0059] Please combine Figure 4 In some embodiments, the high-voltage distribution unit further includes a diagonal beam 610, which is fixed to the frame 500, thereby increasing the strength of the frame 500 and further increasing the strength of the housing 300. The first portion 510 and the second portion 530 both extend horizontally, and the third portion 550 extends vertically. One end of the diagonal beam 610 is fixed to the first portion 510, and the other end is fixed to the third portion 550. The extension direction of the diagonal beam 610 forms an angle with both the horizontal and vertical directions, thus reinforcing the frame 500 in both the horizontal and vertical directions. In some examples, the cover 330 extends horizontally, allowing the first portion 510 to better support and reinforce the cover 330. In some embodiments, the frame 500 is formed by welding together U-shaped steel beams, and the diagonal beam is welded onto the frame 500, making the housing less prone to deformation when subjected to pressure from different directions.

[0060] Please combine Figure 4 , Figure 6 ,as well as Figure 7In some embodiments, the high-voltage power distribution unit further comprises a mounting foot 710. The mounting foot 710 is configured to thicken and strengthen the housing 300. Specifically, the box body 310 comprises a bottom wall 313 opposite to the box cover 330 and a side wall 315 between the box cover 330 and the bottom wall 313. The mounting foot 710 comprises a first leg 711, a second leg 713, and a reinforcing rib 715. In some examples, the mounting foot 710 can be made of high-strength steel. The second leg 713 is fixed to the side wall 315, and the first leg 711 is fixed to the second leg 713 at an end close to the bottom wall 313. The first leg 711 extends in a horizontal direction away from the side wall 315. The reinforcing rib 715 is connected to the surface of the second leg 713 away from the side wall 315 and the surface of the first leg 711 facing the box cover 330. When the second connection part of the connector is connected to the external electrical equipment, the mounting foot 710 can share the pressure of the external electrical equipment on the connector and the housing 300, and can strengthen the housing 300. In some examples, the mounting foot 710 is welded to the side wall 315. The mounting foot 710 can be a long strip structure, which increases the connection area of the mounting foot 710 and the side wall 315, and further strengthens the housing 300.

[0061] In the related art, in the design of the PDU, most of the box bodies of the PDU are made of simple low-strength thin plates by welding. The strength is low, which causes a series of problems. When the high-voltage power distribution unit (PDU) is connected to the external electrical equipment, the high-voltage power distribution unit (PDU) is usually connected to the external electrical equipment through a connector. When the external electrical equipment is connected to the connector of the high-voltage power distribution unit (PDU), the external electrical equipment has a force on the connector, which easily causes the deformation of the housing part where the connector is located. When the box body is subjected to a large force, the box body is easily deformed, and even the four sides of the box body are cracked. In addition, the failure of the welds also causes the failure to meet the protection level requirements.

[0062] In the embodiments of the present application, in a first aspect, a reinforcing member is arranged on the periphery of the mounting hole of the box cover. Since the reinforcing member is arranged on the periphery of the mounting hole, the reinforcing member can strengthen the mounting hole 331 of the box cover, so that the mounting hole 331 is relatively not easy to deform, and the box cover 330 is not easy to deform, thereby achieving the effect of reinforcing the box cover 330.

[0063] In a second aspect, a frame 500 is arranged in the box body 310, thereby being capable of strengthening the housing.

[0064] In a third aspect, the box cover 330 can form the main body part 333 and the surrounding part 335 through a milling process, thereby making the strength of the box cover 330 greater and not easy to deform.

[0065] In the fourth aspect, the shell 300 is reinforced by the installation feet 710.

[0066] Therefore, the strength of the shell 300 is improved, and the reinforcing member, the frame 500 and the installation feet 710 can share the pressure on the shell 300 when the external electrical equipment is connected to the connector of the high-voltage power distribution unit (PDU), so that the shell 300 is not easily deformed.

[0067] In the second aspect, the embodiments of the present application also provide a vehicle comprising the high-voltage power distribution unit.

[0068] The vehicle can be a fuel automobile, a plug-in hybrid electric vehicle or a new energy vehicle, and the present application does not make specific limitations.

[0069] The embodiments of the present application are described in detail above, and the principles and implementation modes of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the method of the present application and its core idea. Meanwhile, for those skilled in the art, the specific implementation modes and application ranges will be changed according to the idea of the present application. In conclusion, the content of the specification should not be understood as a limitation of the present application.
