The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative embodiments to each other. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0057] In the description of the embodiments of the present application, the orientations or positional relationships indicated by the technical terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements indicated thereby must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application.

[0058] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the technical terms "mounting", "connecting", "connecting", "fixing", and the like should be understood in a broad sense, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium, or can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0059] In the description of the embodiments of the present application, the technical terms "first", "second", and the like are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the technical features indicated. In the description of the embodiments of the present application, the term "a plurality of" refers to two or more (including two), and similarly, "a plurality of groups" refers to two or more groups (including two groups), and "a plurality of pieces" refers to two or more pieces (including two pieces).

[0060] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects have an "or" relationship.

[0061] In the related art, the connector shell of the high-voltage connector is fixedly connected with the frame by bolts, and the connector shell and the frame are waterproofed by the sealing ring arranged therebetween. However, the sealing ring is prone to failure due to vibration wear, aging and other reasons after long-term use, thereby causing water to enter the battery pack. Since high-voltage direct current exists at both ends of the high-voltage connector, once the battery pack enters water, it may cause a short circuit inside the battery, further causing the battery to swell, leak, and even catch fire and explode.

[0062] To solve the above technical problems, the application provides a battery pack frame, a battery pack and a vehicle. The battery pack frame, the battery pack and the vehicle provided by the application are described in detail below with reference to the accompanying drawings.

[0063] The application provides a vehicle including a battery pack. The battery pack, also known as a power battery, is an indispensable core component in electric vehicles and hybrid electric vehicles. The battery pack is a high-voltage and large-capacity battery system formed by precisely combining many individual battery units, used for storing and providing electric energy. The battery pack includes a battery pack frame, which is the outermost shell of the battery pack, used to protect the battery units and internal circuits from physical damage and environmental factors (such as moisture and dust).

[0064] The battery pack frame can be surrounded by a plurality of frames 1. At least two high-voltage connectors 2 are provided on the frame 1, as shown in Figure 1 and Figure 2 One of the high-voltage connectors 2 can be positive, and the other can be negative. The high-voltage connector 2 is a key component that connects the battery unit to other high-voltage systems of the vehicle (such as the motor controller, DC / DC converter, charger, etc.), used to transmit the electric energy of the battery pack and ensure efficient flow of current. As shown in Figures 3 to 5 , the high-voltage connector 2 includes a connector shell 100 and a connector assembly 200. The connector shell 100 has a mounting hole 101 inside, and the connector assembly 200 is fixedly arranged in the mounting hole 101. The connector shell 100 is integrally formed with the frame 1.

[0065] The mounting hole 101 in the connector shell 100 provides a mounting base for the connector assembly 200, and the connector assembly 200 is arranged in the connector shell 100 through the mounting hole 101.

[0066] The application provides a scheme in which the connector shell 100 and the frame 1 are integrally formed, eliminating the gap between the connector shell and the frame in the related art, and eliminating the need for a sealing ring to seal the connector shell and the frame. The connection method of the connector shell 100 and the frame 1 is simplified, and the manufacturing process is simple, the sealing performance is reliable, and the like. The application effectively avoids the water ingress caused by the failure of the sealing ring, and improves the safety of the battery pack. Therefore, the application can solve the problem of water ingress in the battery pack caused by the easy failure of the sealing between the high-voltage connector and the frame.

[0067] In addition, the frame 1 and the connector shell 100 can be aluminum alloy pieces; the frame 1 and the connector shell 100 are integrally cast into shape. It should be noted that the frame 1 and the connector shell 100 of the aluminum alloy piece have a very high strength-to-weight ratio, so they can maintain a light weight while ensuring high strength, thereby effectively reducing the weight. In addition, compared with the frame 1 and the connector shell 100 connected by bolts and the like, the frame 1 and the connector shell 100 made of aluminum alloy pieces and integrally cast into shape can have higher connection strength.

[0068] Referring to Figure 4 and Figure 5 In some embodiments, the connector assembly 200 can include an insulating sleeve 210 and a conductive terminal 220; the insulating sleeve 210 is sealingly arranged on the hole wall of the mounting hole 101; an inner wall of one end of the insulating sleeve 210 is provided with a stop portion 211, and the stop portion 211 is provided with a through hole 2110; the conductive terminal 220 includes a conductive column 221 and a conductive row 222 connected to each other; the conductive column 221 is sealingly arranged in the through hole 2110 and extends into the insulating sleeve 210, and an outer periphery of the conductive column 221 is provided with a limiting portion 2210 abutting against the stop portion 211.

[0069] Referring to Figure 6 The conductive column 221, the conductive row 222, and the limiting portion 2210 can be an integral structural piece, of course, the conductive column 221, the conductive row 222, and the limiting portion 2210 can also be a split structural piece; the split structural conductive column 221, the conductive row 222, and the limiting portion 2210 can be processed according to the same or different manufacturing processes, respectively, and then connected into a whole by welding. The conductive column 221, the conductive row 222, and the limiting portion 2210 can be made of copper or copper alloy material, so that the conductive terminal 220 has excellent conductivity.

[0070] During assembly, first, the conductive column 221 is inserted into the through hole 2110 of the stop portion 211 in the insulating sleeve 210 until the limiting portion 2210 of the conductive column 221 abuts against the stop portion 211; then, the conductive column 221 and the insulating sleeve 210 are installed in the mounting hole 101 of the insulating sleeve 210 as a whole. Among them, the insulating sleeve 210 can be connected with the mounting hole 101 in an interference fit, so that at least part of the outer wall of the insulating sleeve 210 is tightly connected with the hole wall of the mounting hole 101, and the conductive column 221 can be connected with the through hole 2110 of the stop portion 211 in an interference fit, so that the outer wall of the conductive column 221 is tightly connected with the inner wall of the through hole 2110, thereby realizing effective sealing between the insulating sleeve 210 and the connector shell 100 and between the insulating sleeve 210 and the conductive column 221.

[0071] Referring to Figure 6 and Figure 8In some embodiments, the end face of the stop portion 211 close to the end of the conductive row 222 can be in the same plane as the end face of the insulating sleeve 210 close to the end of the conductive row 222 along the axial direction of the insulating sleeve 210; the limiting portion 2210 abuts against the end face of the stop portion 211 close to the end of the conductive row 222 and the end face of the insulating sleeve 210 close to the end of the conductive row 222. Figure 6 and Figure 8 As shown in FIGS. 17 and 18, the stop portion 211 can be arranged on the left side of the insulating sleeve 210, and the left end face of the stop portion 211 can be in the same plane as the left end face of the insulating sleeve 210. In this way, the outer dimension of the limiting portion 2210 can be increased, the left end face of the stop portion 211 and the left end face of the insulating sleeve 210 can be abutted by the limiting portion 2210 at the same time, the contact area of the limiting portion 2210 can be effectively increased, the pressure can be reduced, and the service life of the limiting portion 2210 can be improved.

[0072] Referring to Figure 4 and Figure 8 In some embodiments, part of the hole wall of the mounting hole 101 is formed with an annular boss 102; and the insulating sleeve 210 is provided with an annular step 212 corresponding to the annular boss 102, and the surface of the annular step 212 is in interference fit with the surface of the annular boss 102.

[0073] In the embodiments of the present application, the annular boss 102 is arranged on part of the hole wall of the mounting hole 101, and the annular boss 102 is arranged on part of the outer wall of the insulating sleeve 210. In this way, when the insulating sleeve 210 is assembled in the mounting hole 101, part of the outer wall of the insulating sleeve 210 is in interference connection with part of the hole wall of the mounting hole 101, and compared with the interference connection between the entire outer wall of the insulating sleeve 210 and the hole wall of the mounting hole 101, the assembly resistance is significantly reduced. Therefore, under the premise of ensuring the sealing effect, the workload of the installation personnel can be reduced, the stress on the insulating sleeve 210 can be reduced, and the deformation amount can be reduced.

[0074] Referring to Figures 6 to 8 In some embodiments, the connector assembly 200 can further include a plug cover 230, the plug cover 230 including a cover body 231 and a cover rim 232, the cover body 231 being provided with an avoiding hole 2310, and the cover body 231 being arranged through the conductive row 222 and abutting against the limiting portion 2210 through the avoiding hole 2310; in other words, the conductive row 222 can pass through the cover body 231 through the avoiding hole 2310. The cover rim 232 is arranged around the edge of the cover body 231, and the cover rim 232 is clamped between the outer wall of the insulating sleeve 210 and the hole wall of the mounting hole 101.

[0075] It can be understood that the plug cover 230 is used to protect and hide the conductive row 222, prevent substances such as dust, moisture, corrosive substances, etc. from affecting the conductive row 222, thereby reducing the risk of short circuit, electric leakage and other electrical faults. In addition, the cover body 231 of the plug cover 230 can also provide a certain degree of insulation protection to prevent accidental electric shock of the electrical connection point and reduce the risk of electric shock.

[0076] The annular boss 102 can be away from the mounting hole 101 and close to one end of the conductive row 222, and correspondingly, the annular step 212 can also be away from the insulating sleeve 210 and close to one end of the conductive row 222. Exemplarily, as shown in Figure 4 and Figure 6 , the annular boss 102 can be arranged at the middle part of the mounting hole 101, and the annular step 212 is arranged at the middle part of the insulating sleeve 210, so that the annular boss 102 and the annular step 212 close to one side of the conductive row 222 can form a gap. When assembled, the cover edge 232 of the plug cover 230 can be inserted into the gap. In order to firmly fix the plug cover 230, the thickness of the cover edge 232 can be reasonably arranged, so that the outer peripheral wall of the cover edge 232 inserted into the gap is in close contact with the hole wall of the mounting hole 101, and the inner peripheral wall of the cover edge 232 inserted into the gap is in close contact with the outer wall of the insulating sleeve 210, so that the connector shell 100 and the insulating sleeve 210 clamp the cover edge 232.

[0077] Referring to Figure 6 , in some embodiments, the outer wall of the insulating sleeve 210 close to one side of the conductive row 222 is provided with a positioning notch 213; the inner wall of the cover edge 232 is provided with a positioning protrusion 2320, and the positioning protrusion 2320 is connected with the positioning notch 213 in cooperation. In this way, when the plug cover 230 is installed, the positioning protrusion 2320 of the cover edge 232 can be aligned with the positioning notch 213 of the insulating sleeve 210 to realize the quick and accurate installation of the plug cover 230. The number of the positioning notch 213 can be multiple, for example, two, three, four, etc. The multiple positioning notches 213 can be evenly arranged around the axis of the insulating sleeve 210. The number and position of the positioning protrusion 2320 correspond to the positioning notch 213, which will not be described here.

[0078] Referring to Figure 6 and Figure 8In some embodiments, the conductive row 222 is provided with a connecting hole (not shown in the figure); the conductive terminal 220 can further include a connecting sleeve 223, which includes a first section and a second section 2231 (not shown in the figure) connected to each other, the first section is detachably arranged in the connecting hole, and the second section 2231 extends out of the surface of the conductive row 222 and is provided with an internal thread. The first section can be arranged in the connecting hole of the conductive row 222 in a clamping manner. The second section 2231 is provided with an internal thread, and only needs to be rotated to be fixed, without the need of using additional tools or complex operations, so that the conductive row 222 is more convenient when connected with other devices or connectors. In addition, the threaded rotary connection can also make the connection between the conductive row 222 and other devices or connectors more stable and reliable, reducing the possibility of loosening or falling off. When assembling the battery pack frame, in order to avoid interference of the connecting sleeve 223 with the installation of the plug cover 230, the first section of the connecting sleeve 223 is not connected with the connecting hole of the conductive row 222, but after the plug cover 230 is arranged on the conductive row 222 through the avoiding hole 2310 on the cover body 231 of the plug cover 230, the first section of the connecting sleeve 223 is connected with the connecting hole of the conductive row 222.

[0079] In some embodiments, the insulating sleeve 210 and the plug cover 230 can both be plastic parts, and the material of the plastic parts can be polypropylene (PP), polyvinyl chloride (PVC), etc. In this way, while ensuring lightweight, the insulating performance of the high-voltage connector 2 can also be effectively ensured.
