[0004] Electric vehicles typically include an electrical structure with high-voltage modules, such as a battery pack and controller. This electrical structure often incorporates connectors for connecting to external circuits. Current electrical structures often feature a support frame on a base in the lower housing, with an adapter plate supporting the connector. The support frame is connected to the adapter plate to hold it in place, and the adapter plate is connected to the upper housing of the electrical structure to secure the connector. However, this structure is inconvenient for assembly.

[0005] Application content

[0006] The purpose of this application is to provide an electrical structure, battery device, chassis, and vehicle to improve the problem of inconvenient fixed assembly of connectors in related technologies.

Using a flexible conductive component to connect the high-voltage module and the connector, the position of the connector can be easily adjusted, thereby reducing the positional accuracy requirements before the connector is connected to the first housing. This facilitates the connection and fixation of the connector to the first housing and makes assembly convenient.

[0014] In some embodiments, the connector includes a body and a support platform, the support platform being disposed around the body, a portion of the body extending out of a first housing through a first opening, the support platform being fixedly connected to the first housing, and a flexible conductive element being connected to the body.

[0016] In some embodiments, the electrical structure includes a support structure having a second opening for the main body to be adapted into, a support platform being supported on the support structure, and the support structure being mounted on a second housing.

[0017] The above technical solution involves setting up a support structure, installing the support structure on the second housing, and supporting the support platform, thereby supporting the connector on the second housing and realizing the connection between the connector and the first and second housings. This provides a more stable support for the connector and facilitates its use. Furthermore, a second opening is provided on the support structure, into which the main body is placed, allowing the support platform to be supported. This facilitates the connection between the connector and the support structure, making assembly easier. The processing precision requirements for the support structure are also lower, thus reducing manufacturing costs.

[0018] In some embodiments, one side of the second opening is provided to be open.

[0019] The above technical solution can reduce the positional restriction of the sidewall of the second opening on the main body, facilitate the assembly of the main body, reduce the processing accuracy requirements of the support structure, and facilitate the processing and manufacturing of the support structure.

Moreover, the support platform can provide good support for the main body, improve the connection strength between the main body and the support platform, and maintain a good sealing effect between the main body and the support platform.

[0039] In some embodiments, a first sealing structure is provided between the support platform and the first housing.

[0040] The above technical solution improves the sealing performance between the support platform and the first housing by setting a first sealing structure, thereby improving the sealing performance of the electrical structure.

[0041] In some embodiments, the first sealing structure includes a first sealing ring, and a positioning groove is provided on the support platform for the first sealing ring to be adapted into.

[0042] The above technical solution uses a first sealing ring, which has a simple structure, low cost, and good sealing effect; the positioning groove on the support platform makes it easy to install the first sealing ring and facilitates assembly.

[0043] In some embodiments, the support platform is fixedly connected to the first housing by a second fastener.

[0044] The above technical solution uses a second fastener to connect the support platform and the first housing, resulting in a stable and convenient connection.

[0045] In some embodiments, the flexible conductive element is fixedly connected to the connector by a third fastener.

[0071] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0072] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments in any suitable manner.

[0073] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0074] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0075] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0076] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces). "Several" means one or more, unless otherwise explicitly specified.

[0077] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0078] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

N If one of the C components, such as C2, is closer to the B component than the other C components, then B is adjacent to C2, or C2 is adjacent to B.

[0081] Electric vehicles are vehicles that are driven by an electric motor. Electric vehicles can be purely electric vehicles or hybrid vehicles that combine electric and motor-driven power.

[0082] Electric vehicles typically include electrical components such as battery packs and controllers. The controller is connected to the battery pack to control the power supply from the battery pack to the vehicle's propulsion system, thus driving the vehicle. Since controlling the charging and discharging of the battery pack and the distribution of power often involves high voltage and high current, high-voltage modules are frequently incorporated into the controller and battery pack to enable the transmission of high voltage, high current, and high power. For connection between the electrical components and external circuits, connectors such as sockets, plugs, and interfaces are often included. Correspondingly, copper busbars are used to connect the connectors to the high-voltage modules to withstand the high current transmission. Due to the high structural strength of copper busbars, the busbars can restrict the position of the connectors after they are fixed. Therefore, current electrical structures often include a support frame and an adapter plate. The connector is fixed to the adapter plate, while the support frame is fixed to the lower housing of the electrical structure and also to the adapter plate to support and position the adapter plate and connector. Finally, the adapter plate is connected to the upper housing to secure the connector to it. However, this structure requires the adapter plate to be fixedly connected to the upper shell and the support frame, and the support frame needs to be fixedly connected to the lower shell. Furthermore, the periphery of the upper shell and the periphery of the lower shell also need to be fixedly connected to form a complete electrical structure shell. This results in a secondary fixed connection between the upper and lower shells. Consequently, the connection between the adapter plate and the upper shell can only be made after the upper and lower shells are fixedly connected. This requires the adapter plate to have high positional accuracy. Since the adapter plate is positioned by the support frame before being fixed to the upper shell, the processing accuracy requirements for the support frame are high. Moreover, this assembly method is inefficient and inconvenient to assemble.

[0083] Based on the above considerations, in order to improve the problem of inconvenient fixed assembly of connectors in related technologies, this application provides an electrical structure that uses a flexible conductive component to connect the high-voltage module and the connector. Due to the flexible deformation of the flexible conductive component, the position of the connector can be easily adjusted to reduce the positional accuracy requirements before the connector is connected to the first housing. Furthermore, the connector can be fixedly connected to the first housing of the electrical structure first, and then the first housing can be fixed to the second housing. The connection and assembly are convenient and efficient.

[0084] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0085] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0086] Vehicles are a common means of transportation. Vehicles include body structures. As vehicles develop, body structures are also constantly being improved to adapt to new vehicle development trends and needs.

[0087] Vehicles typically consist of a body structure, powertrain structure, and interior components. To alleviate the problems of high assembly difficulty and low production efficiency, the body structure can be divided into the upper body and the chassis; the upper body and chassis can be manufactured separately and then assembled. The upper body mainly includes the A-pillar, B-pillar, C-pillar, front and rear bulkheads, and front and rear doors. The chassis mainly consists of the body floor and frame. The frame is the main supporting and load-bearing structure of the chassis. For ease of assembly, the frame usually includes three sections: the front compartment, the chemical compartment, and the rear compartment. Some frames also include a subframe to connect to the vehicle's suspension system; the subframe is usually connected to the front compartment.

[0088] Referring to Figures 1 and 2, vehicle 100 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or extended-range electric vehicles, etc. Vehicle 100 includes a body structure 101, which includes a superstructure 120 and a chassis 110. The superstructure 120 is connected to the chassis 110 for easy assembly and improved assembly efficiency. Furthermore, the superstructure 120 and chassis 110 can be manufactured separately to facilitate processing and reduce the manufacturing difficulty of the body structure 101.

[0089] In some embodiments, the chassis 110 includes a frame 200 that supports the upper body 120.

[0090] In some embodiments, a battery device 300 is disposed inside the vehicle 100, and the battery device 300 may be located at the bottom, front, or rear of the vehicle 100. The battery device 300 can be used to power the vehicle 100; for example, the battery device 300 can serve as the operating power source for the vehicle 100. The vehicle 100 may also include a controller 500 and a motor 400, the controller 500 controlling the battery device 300 to supply power to the motor 400, for example, to meet the power requirements of the vehicle 100 during starting, navigation, and driving.

[0091] In some embodiments, the battery device 300 can not only serve as the operating power source for the vehicle 100, but also as the driving power source for the vehicle 100, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100.

[0092] Please refer to Figures 1 and 2. In some embodiments, the vehicle 100 and chassis 110 have multiple orientations, including: up, down, front, rear, left, and right, all of which are based on the orientation of the vehicle 100. That is, the direction from the front to the rear of the vehicle is from front to back, and the direction from the roof to the bottom of the vehicle is from top to bottom. The driver's seat and the passenger seat are arranged in a left-right direction. For example, the front-rear direction of the vehicle 100 is also called the length direction, which is the X direction; the left-right direction of the vehicle 100 is also called the width direction, which is the Y direction; and the height direction of the vehicle 100 is also called the vertical direction, which is the Z direction. Correspondingly, in the forward-backward direction (X) of vehicle 100, the forward direction refers to the direction vehicle 100 faces forward, i.e., forward is the F direction; the backward direction refers to the direction vehicle 100 faces backward, i.e., backward is the B direction. In the left-right direction (Y) of vehicle 100, the right direction refers to the direction vehicle 100 faces to the right, i.e., right is the R direction; the left direction refers to the direction vehicle 100 faces to the left, i.e., left is the L direction. In the height direction (Z) of vehicle 100, the upward direction refers to the direction vehicle 100 faces upward, i.e., upward is the U direction; the downward direction refers to the direction vehicle 100 faces downward, i.e., downward is the D direction. The up, down, forward, backward, left, and right positions of the frame 200 are consistent with the corresponding up, down, forward, backward, left, and right positions of vehicle 100. In addition, for the 200 frame, the longitudinal direction is along the front-to-back direction X, which allows for a certain error or small angle deviation, such as within 10 degrees; the lateral direction is along the left-to-right direction Y, which also allows for a certain error or small angle deviation, such as within 10 degrees.

[0093] Referring to Figure 3, this application embodiment provides a battery device 300. The battery device 300 may include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly may include multiple battery cells 320, which are connected in series, parallel, or mixed connections via a busbar.

[0094] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells 320.

[0095] As an example, a battery cell assembly can be a battery module, which consists of multiple battery cells 320 arranged and fixed together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells 320 together with cable ties.

[0096] In some embodiments, the battery device 300 may be a battery pack, which includes a housing 310 and one or more battery cell assemblies housed in the housing 310.

[0097] As an example, the battery cell assembly can be a battery module, and the battery cell assembly can be housed in the housing 310 by fixing the battery module in the housing 310.

[0098] As an example, the battery cell assembly can also be housed in the housing 310 by directly fixing multiple battery cells 320 to the housing 310.

[0099] In some embodiments, the housing 310 may include a top cover 311, a frame 313, and a bottom plate 312. The top cover 311 and the bottom plate 312 are respectively connected to opposite sides of the frame 313, thereby forming a closed space inside the housing 310 to accommodate the battery cells 320. The frame 313 refers to the partial structure forming the peripheral sidewall of the housing 310, the top cover 311 refers to the plate-like structure forming the top of the housing 310, and the bottom plate 312 refers to the plate-like structure forming the bottom of the housing 310.

[0100] In some embodiments, the housing 310 may include a first housing and a second housing, which are fastened together to form a closed space inside the housing 310 to house the battery cells 320. Here, "closed" refers to covering or shutting down; it can be sealed or unsealed. The first housing may be a top cover or a bottom plate of the housing 310. Both the first and second housings may also be hollow structures with an opening on one side, with the opening side of the first housing fitting over the opening side of the second housing.

[0101] In some embodiments, the housing 310 includes a reinforcing beam 314 connected to the frame 313. The reinforcing beam 314 is a structural member provided on the housing 310 to increase the structural strength of the housing 310. Providing a reinforcing beam 314 and connecting it to the frame 313 enhances the structural strength of the housing 310.

[0102] In some embodiments, the reinforcing beam 314 includes a mounting beam 3141, which is fixedly connected to the frame 313 and is used to connect an external device using the battery device 300 to support the battery device 300 on the device.

[0103] In some embodiments, the reinforcing beam 314 includes an expansion beam installed inside the housing 310 to increase the structural strength of the housing 310, and can also be used to support the battery cell 320 to limit the expansion deformation of the battery cell 320.

[0104] In some embodiments, the expansion beam can also be connected to the bottom plate 312 of the box 310 to better fix the expansion beam in the box 310.

[0105] In some embodiments, the housing 310 may be part of the chassis structure of the vehicle 100. For example, a portion of the housing 310 may be at least a portion of the floor of the vehicle 100, or a portion of the housing 310 may be at least a portion of the crossbeams and longitudinal beams of the vehicle 100.

[0106] Referring to Figure 3, the battery device 300 may include an electrical structure 60, which is mounted on a housing 310 and supported by the housing 310. The electrical structure 60 can be a structure used to control the power distribution and charging / discharging of the battery device 300. For example, the electrical structure 60 may be a battery management system. Alternatively, the electrical structure 60 may include a battery management system and other electronic control structures, such as an energy distribution unit to control the charging / discharging sequence and power of the individual battery cells 320 in the battery device 300.

[0107] In some embodiments, the electrical structure 60 may be mounted on the housing 310 of the battery device 300 so that the housing 310 can support the electrical structure 60, so that the electrical structure 60 does not occupy the space inside the housing 310, and more battery cells 320 can be installed in the housing 310 to increase the capacity of the housing 310.

[0108] In some embodiments, the battery cell 320 may be installed in the housing 61 of the electrical structure 60, that is, the housing 61 of the electrical structure 60 may serve as the enclosure 310 of the battery device 300, so as to utilize the space in the housing 61 of the electrical structure 60 so that the electrical structure 60 can better control the charging and discharging of the battery cell 320.

[0109] In some embodiments, the chassis 110 may include an electrical structure 60 to control the operation of the chassis 110, such as controlling the operation of the motor 400 on the chassis 110.

[0110] In some embodiments, the electrical structure 60 can be applied not only to the battery device 300 and the chassis 110 of the vehicle 100, but also to structures that require power distribution and control, such as energy storage devices.

[0111] In some embodiments, the electrical structure 60 includes a housing 61 and an electrical control module 64, which is mounted in the housing 61 and supported and protected by the housing 61. The electrical control module 64 refers to the power or signal control structure in the electrical structure 60. Depending on the application scenario of the electrical structure 60, the electrical control module 64 may include different module structures.

[0112] As an example, electrical structure 60 is applied to battery device 300, and electronic control module 64 may include battery management system, energy distribution unit, etc.

[0113] As an example, electrical structure 60 is applied to an energy storage device, and the electrical control module 64 may include one or more of a main control module, a central control module, and a power distribution module. As an example, the main control module can serve as the battery management unit for the battery cluster, used to monitor and manage the battery cluster. The main control module can monitor information such as current, voltage, power, or temperature of the battery cluster. For example, it can control the charging and discharging current and voltage of the battery cluster. The main control module includes modules such as a slave battery management unit (SBMU) and a fusion switch. As an example, the central control module can serve as the battery management unit for the energy storage device, used to monitor and manage the energy storage device. The central control module can monitor information such as current, voltage, power, state of charge, or temperature of the energy storage device. For example, it can control the charging and discharging current and voltage of the energy storage device. As an example, the central control module includes modules such as an insulation monitoring module (IMM), a master battery management unit (MBMU), an Ethernet (ETH) module, and a fiber optic conversion module. As an example, a power distribution module can be used to distribute power to modules in an energy storage device that require electricity.

[0114] In some embodiments, referring to Figures 1 to 3, the electrical structure 60 is applied to the chassis 110 of the vehicle 100, and the electronic control module 64 of the electrical structure 60 includes a high-voltage module 641 for controlling the electrical power of the chassis 110 of the vehicle 100.

[0115] High-voltage module 641 refers to at least part of the high-voltage circuit structure or electronic device in vehicle 100 used to control the distribution and use of electrical energy.

[0116] The high-voltage module 641 is used to control the electrical energy of the chassis 110 of the vehicle 100, which means that the high-voltage module 641 can be used to control the distribution and use of at least a portion of the high-voltage portion of the electrical energy in the vehicle 100.

[0117] In some embodiments, the electronic control module 64 may also include other circuit structures, such as a low-voltage module that controls the distribution and use of electrical energy in the chassis 110 of the vehicle 100.

[0118] As an example, the electronic control module 64 may also include a communication module for communicating between the chassis 110 of the vehicle 100 and the outside.

[0119] As an example, the electronic control module 64 may also include a module for the battery device 300 to communicate with the outside.

[0120] In some embodiments, the high-voltage module 641 includes a battery high-voltage module for controlling the charging and discharging of the battery cell 320, and / or a vehicle high-voltage module for driving the vehicle 100.

[0121] A battery high-voltage module refers to the circuit structure in the battery device 300 used to control the charging and discharging of individual battery cells 320. For example, the battery high-voltage module performs voltage conversion and regulation, such as boosting the lower voltage output by the battery device 300 to a higher operating voltage to meet the needs of specific equipment or systems. As an example, in the vehicle 100, it converts the DC power from the battery device 300 into the high-voltage AC power required to drive the motor. Furthermore, the battery high-voltage module performs energy transfer and management, such as efficiently transferring the energy stored in the battery device 300 to various loads such as motors and electronic devices, reducing energy loss and improving energy utilization efficiency through optimized circuit design and control strategies.

[0122] The high-voltage module of a battery may include a Battery Energy Distribution Unit (BDU). The BDU is a crucial component of the high-voltage circuit in an electric vehicle. It controls the power-on / off, pre-charge, and charging processes of the high-voltage electrical circuit, significantly impacting the vehicle's lifespan, control strategies, and high-voltage electrical safety.

[0123] The vehicle high-voltage module is a circuit structure in vehicle 100 used to control the conversion and transmission of high-voltage electrical energy to drive the vehicle 100. For example, the vehicle high-voltage module performs energy conversion and transmission, such as converting the high-voltage DC output from the battery unit 300 into different forms of energy to meet the needs of various systems in vehicle 100. As an example, an inverter converts DC to AC to power the drive motor 400; a DC-DC converter steps down the high-voltage DC to low-voltage DC to power onboard electronic devices. Furthermore, the vehicle high-voltage module performs system control and coordination, working closely with the vehicle control system to achieve precise control of the high-voltage system. Based on factors such as the vehicle 100's driving status, driver commands, and battery status, it adjusts the operating mode and parameters of the high-voltage system to ensure the safe and stable operation of vehicle 100, and coordinates the work between various high-voltage components, such as the drive motor, battery management unit, and charging system, to achieve integrated operation of the entire vehicle high-voltage system. For example, the high-voltage module of the vehicle plays a safety protection role, such as setting up multiple safety protection functions to prevent harm to the vehicle and personnel in the event of a high-voltage system failure. These functions include overvoltage protection, overcurrent protection, short circuit protection, and leakage protection. When an abnormality occurs in the high-voltage system, the high-voltage power supply can be cut off in time to ensure the safety of the vehicle and personnel.

[0124] The high-voltage module for a vehicle may include an on-board charger (OBC), a DC-DC converter, and a power distribution unit (PDU). An on-board charger is a device installed on the vehicle 100 that converts alternating current (AC) to direct current (DC) to charge the vehicle 100's battery pack 300. A DC-DC converter is an electronic device that converts DC power from one voltage level to another. A power distribution unit is a device used in an electrical system to distribute and manage power.

[0125] As an example, the high-voltage module 641 may consist only of the battery high-voltage module, so the electrical structure 60 may be used only for the battery device 300. Of course, if the high-voltage module 641 consists only of the battery high-voltage module, the electrical structure 60 may also be applied to the chassis 110 of the vehicle 100.

[0126] As an example, the high-voltage module 641 may consist only of the vehicle's high-voltage module in order to control the vehicle 100 to operate properly.

[0127] As an example, when the high-voltage module 641 includes a battery high-voltage module and a vehicle high-voltage module, integrating the battery high-voltage module and the vehicle high-voltage module into the electronic control module 64 can improve the integration level. The battery high-voltage module can also avoid occupying the internal space of the battery device 300, which can reduce the volume of the battery device 300, increase the energy density of the battery device 300, and reduce the thermal impact between the battery high-voltage module and the battery cell 320.

[0128] Referring to Figures 4 to 8, according to some embodiments of this application, an electrical structure 60 is provided, including: a housing 61, a high-voltage module 641, a connector 62, and a flexible conductive element 63. The housing 61 includes a first housing 611 and a second housing 612 connected to the first housing 611, the first housing 611 and the second housing 612 forming a receiving space 610. The high-voltage module 641 is mounted in the receiving space 610. The connector 62 is mounted in the receiving space 610. The flexible conductive element 63 connects the high-voltage module 641 and the connector 62. The connector 62 is fixed to the first housing 611, and the first housing 611 has a first opening 6111 exposing the connector 62.

[0129] The outer casing 61 refers to the shell structure formed by the outline of the electrical structure 60. The outer casing 61 protects the electrical control module 64. The outer casing 61 can be made of materials such as metal, plastic, or ceramic.

[0130] High voltage module 641 refers to at least a portion of a high voltage circuit structure or electronic device used to control the distribution and use of electrical energy.

[0131] Connector 62 is an interface component used to connect high-voltage module 641 and external circuits. Connector 62 can be a socket, plug or other form of electrical connection interface. The type and design of connector 62 can be selected and adapted as needed to adapt to connecting different circuits and can withstand high power and high current power transmission.

[0132] The flexible conductive component 63 refers to a conductive structural component with a certain degree of flexibility, allowing it to bend and deform within a certain area, thereby adapting to complex installation spaces and providing good conductivity. The flexible conductive component 63 can be formed by multiple strands of wire or by using conductive strips braided from wire filaments. The flexible conductive component 63 can be made of polymer conductive materials or metal materials to achieve both good conductivity and a certain degree of flexibility.

[0133] The first housing 611 and the second housing 612 are connected to each other to form two housing components of the outer shell 61.

[0134] The first housing 611 and the second housing 612 are fastened together, forming a closed space inside the outer shell 61 to house the high-voltage module 641 and other electronic control modules 64. Here, "closed" refers to covering or shutting off; it can be sealed or unsealed. The second housing 612 can be a hollow structure with one open end, and the first housing 611 can be a plate-like structure, covering the open side of the second housing 612. The first housing 611 can be the top or bottom wall panel of the outer shell 61. Alternatively, both the first housing 611 and the second housing 612 can be hollow structures with one open end, with the open side of the first housing 611 covering the open side of the second housing 612.

[0135] The high-voltage module 641 is installed in the housing space 610 so that the housing 61 can support and protect the high-voltage module 641.

[0136] Connector 62 is installed in housing space 610 to be supported and protected by housing 61.

[0137] The connector 62 is fixed to the first housing 611 so that the first housing 611 supports the connector 62.

[0138] The first opening 6111 refers to the opening structure provided on the first housing 611. The position of the first opening 6111 corresponds to the position of the connector 62, so that when the connector 62 is installed on the first housing 611, a part of the connector 62 can be exposed through the first opening 6111 to realize the connection of external circuits and power transmission.

[0139] Since the high-voltage module 641 is fixed in the housing 61, and the high-voltage module 641 and the connector 62 are connected by a flexible conductive component 63, the connector 62 can move slightly before being fixed to the first housing 611. This allows the connector 62 to be fixed to the first housing 611 before the first housing 611 is installed to the second housing 612, and then connected to the second housing 612. This connection is convenient and can effectively improve the overall assembly efficiency of the electrical structure 60.

[0140] In the technical solution of this application embodiment, by fixing the connector 62 to the first housing 611, the connection is convenient. By using the flexible conductive part 63 to connect the high voltage module 641 and the connector 62, the position of the connector 62 can be easily adjusted, thereby reducing the positional accuracy requirements before the connector 62 is connected to the first housing 611. This facilitates the connection and fixation of the connector 62 and the first housing 611, and makes assembly convenient.

[0141] In some embodiments, please refer to Figures 4 and 5. The connector 62 includes a main body 621 and a support platform 622. The support platform 622 is disposed around the main body 621. A portion of the main body 621 extends out of the first housing 611 through a first opening 6111. The support platform 622 is fixedly connected to the first housing 611. A flexible conductive element 63 is connected to the main body 621.

[0142] The main body 621 refers to the main part of the connector 62, which is used to connect external circuits. The main body 621 is connected to the flexible conductive element 63 so that when the external circuit is connected to the main body 621, the external circuit can be connected to the flexible conductive element 63.

[0143] The support platform 622 refers to a boss or plate-like structure surrounding the main body 621. The support platform 622 can be made of materials such as plastic, bakelite, or ceramic to provide good insulation properties. Alternatively, it can be made of metals such as steel or copper to provide good mechanical strength. In some embodiments, the support platform 622 may also be designed with heat dissipation capabilities to help reduce the temperature of the connector 62 under high-current operating conditions. The structural design of the support platform 622 also allows for adjustments to its size and shape to accommodate different sizes and shapes of the first opening 6111.

[0144] A support platform 622 is provided to support the main body 621, so as to facilitate its fixed connection with the first housing 611, thereby fixing the main body 621 to the first housing 611.

[0145] A portion of the main body 621 extends out of the first housing 611 through the first opening 6111 to facilitate connection to external circuits. During assembly, the main body 621 can be positioned by the side wall of the first opening 6111, thereby positioning the support platform 622 to facilitate connection of the support platform 622 to the first housing 611.

[0146] The above technical solution provides a main body 621 that extends out of the first housing 611 for easy connection to external circuits and convenient use; and a support platform 622 that supports the main body 621 and is also convenient for fixed connection with the first housing 611 for easy assembly.

[0147] In some embodiments, please refer to Figures 4, 6 to 8. The electrical structure 60 includes a support structure 65. The support structure 65 has a second opening 6511 for the main body 621 to be adapted into. The support platform 622 is supported on the support structure 65. The support structure 65 is mounted on the second housing 612.

[0148] The support structure 65 refers to the structure used to support the connector 62. The support structure 65 can be block-shaped, plate-shaped, column-shaped, etc. The design of the support structure 65 can be adapted to the shape and size of the main body 621. The second opening 6511 refers to the opening structure provided on the support structure 65. The size and shape of the second opening 6511 match the main body 621 so that the main body 621 can be placed in the second opening 6511 and positioned through the second opening 6511.

[0149] As an example, the support structure 65 can use a block-shaped base with a second opening 6511 for the main body 621 to be inserted into, so that the support platform 622 can be placed on the block-shaped base. As an example, the support structure 65 can use a plate with a second opening 6511. The main body 621 is inserted into the second opening 6511, and the plate supports the support platform 622, thereby supporting the connector 62. As an example, the support structure 65 can also use multiple rods or columns spliced ​​together to form a frame with a second opening 6511, so that the main body 621 can be inserted into and support the support platform 622.

[0150] The support structure 65 is mounted on the second housing 612, and the second housing 612 supports the support structure 65. The support structure 65 has a second opening 6511. When the support platform 622 of the connector 62 is fixed to the first housing 611 and the first housing 611 is assembled onto the second housing 612, the main body 621 can be inserted into the second opening 6511, allowing the support structure 65 to support the support platform 622. This facilitates assembly and allows the connector 62 to be supported by the second housing 612, thus better securing the connector 62. The first housing 611 and the second housing 612 cooperate to support the connector 62, improving connection strength.

[0151] Through the above technical solution, a support structure 65 is set up and installed on the second housing 612. The support structure 65 supports the support platform 622, thereby supporting the connector 62 on the second housing 612, realizing the connection between the connector 62 and the first housing 611 and the second housing 612, so as to more stably support the connector 62 and facilitate the use of the connector 62. A second opening 6511 is set on the support structure 65, and the main body 621 is placed into the second opening 6511, so that the support platform 622 is supported on the support structure 65. This can facilitate the connection between the connector 62 and the support structure 65, facilitate assembly, and reduce the processing precision requirements of the support structure 65, thereby reducing manufacturing costs.

[0152] In some embodiments, the sidewall of the second opening 6511 is clearance-fitted with the periphery of the main body 621, which facilitates the insertion of the main body 621 into the second opening 6511, making assembly easier, and also reduces the machining accuracy requirements of the support structure 65, thereby reducing the cost of manufacturing the support structure 65.

[0153] In some embodiments, one side of the second opening 6511 is provided to be open.

[0154] The side of the second opening 6511 refers to the side where the sidewall forming the second opening 6511 is located.

[0155] One side of the second opening 6511 is open, meaning that there is no sidewall on one side of the second opening 6511, so that the second opening 6511 is not closed, so that the main body 621 can be inserted into the second opening 6511, which facilitates the installation of the main body 621.

[0156] As an example, the overall shape of the second opening 6511 can be similar to a U-shape, meaning that the second opening 6511 is open only on one side. With this design, the main body 621 can be easily inserted from the U-shaped opening side and positioned and fixed on the other side. This design not only simplifies the assembly process but also enhances the flexibility of the structure.

[0157] As an example, the overall shape of the second opening 6511 can be similar to a C-shape. That is, the second opening 6511 not only has no sidewall on one side, but also at least one side adjacent to that side has no sidewall, so that the main body 621 of the connector 62 can be inserted more flexibly from the second opening 6511.

[0158] As an example, the sidewall of the second opening 6511 can surround at least half of the periphery of the main body 621. This facilitates the flexible insertion of the main body 621 into the second opening 6511 and allows the sidewall of the second opening 6511 to stably support the support platform 622 around the main body 621, thereby providing stable support for the connector 62. Furthermore, this design of the second opening 6511 reduces material usage, lowers costs, and also facilitates the fabrication of the support structure 65.

[0159] The above technical solution can reduce the positional restriction of the sidewall of the second opening 6511 on the main body 621, facilitate the assembly of the main body 621, reduce the processing accuracy requirements of the support structure 65, and facilitate the processing and manufacturing of the support structure 65.

[0160] In some embodiments, the second opening 6511 may also be a closed opening, that is, the second opening 6511 is provided with sidewalls on all sides to stably support the support platform 622.

[0161] In some embodiments, the support structure 65 includes a bracket 651 and a support 652. The support 652 is mounted on the second housing 612, the bracket 651 is connected to the support 652, and the bracket 651 is provided with a second opening 6511.

[0162] The bracket 651 refers to the structure in the support structure 65 that adapts to support the connector 62. The bracket 651 can be plate-shaped, block-shaped, or similar. A second opening 6511 is provided on the bracket 651 so that the main body 621 is placed in the bracket 651, and the bracket 651 supports the support platform 622, thereby supporting the connector 62. The bracket 651 can be made of materials such as metal, ceramic, or plastic.

[0163] Support 652 refers to the part of the support structure 65 used to connect with the second housing 612. Support 652 is provided to facilitate connection to the second housing 612. When the bracket 651 and support 652 are connected, the support structure 65 can be installed entirely onto the second housing 612 for easy assembly. Support 652 can be made of materials such as metal, ceramic, or plastic. The shape of support 652 can be designed according to the shape of the corresponding area on the second housing 612 to be connected, as well as the shape of the connection point with the bracket 651.

[0164] Through the above technical solution, a support 652 is provided to facilitate the fixed connection of the second housing 612, and a bracket 651 is provided to facilitate the support of the connector 62, thereby facilitating the connection of the connector 62 to the second housing 612 and making assembly convenient.

[0165] In some embodiments, the support 652 and the bracket 651 can be manufactured separately and then connected together. This allows for easy adjustment of the shape of the support 652 as needed and also facilitates the connection of the support 652 to the second housing 612.

[0166] In some embodiments, the support 652 and the bracket 651 may also be an integral structure, that is, the support structure 65 is an integral structure, so as to facilitate the overall fabrication of the support structure 65.

[0167] In some embodiments, the second housing 612 has a bottom wall plate 6121 and a side wall plate 6122 disposed around the bottom wall plate 6121, and the support 652 is fixedly connected to the side wall plate 6122.

[0168] Bottom wall panel 6121 refers to the wall panel on the side of the second housing 612 that faces away from the first housing 611. Side wall panel 6122 refers to the wall panel that forms the side wall of the outer shell 61.

[0169] As an example, the side wall panel 6122 and the bottom wall panel 6121 can be manufactured separately and then connected together. This facilitates manufacturing and allows for adjustment of the shape and thickness of the side wall panel 6122 and the bottom wall panel 6121, thereby determining the structural strength of the second shell 612. The side wall panel 6122 and the bottom wall panel 6121 can be fixedly connected by welding, riveting, bolting, or other methods.

[0170] As an example, the bottom wall panel 6121 and the side wall panel 6122 can also be integrally formed, such as by using sheet metal stamping to form the second housing 612 and making the bottom wall panel 6121 and the side wall panel 6122.

[0171] The support 652 is fixedly connected to the side wall plate 6122 so that the support 652 is supported by the side wall plate 6122.

[0172] By connecting the support 652 to the side wall plate 6122 of the second housing 612, the support 652 and the bottom wall plate 6121 of the second housing 612 can be separated, thereby reducing the space occupied by the support structure 65 and improving the space utilization rate. Moreover, the size of the support 652 and the bracket 651 can be made smaller, thereby reducing the use of materials and lowering costs.

[0173] In some embodiments, the support 652 may be connected to the bottom wall plate 6121 of the second housing 612 so that the support 652 can be supported by the bottom wall plate 6121, thereby supporting the support structure 65.

[0174] In some embodiments, the support 652 and the side wall plate 6122 can be connected and fixed in various ways, such as by welding, riveting or threaded connection, to adapt to different installation requirements and process requirements. The specific design and use can be selected according to the needs.

[0175] In some embodiments, a plurality of supports 652 are provided, and supports 652 are respectively installed on adjacent side wall panels 6122 of the second housing 612, and each support 652 is connected to the bracket 651.

[0176] Multiple refers to two or more. The adjacent side panels 6122 of the second housing 612 are respectively equipped with supports 652. That is to say, in the adjacent side panels 6122 of the second housing 612, each side panel 6122 is equipped with at least one support 652 in order to cooperate and stably support the bracket 651.

[0177] By using the above technical solution, multiple supports 652 can be set up, and each support 652 can be made smaller to reduce the use of materials and the space occupied by the support 652. By installing supports 652 on the adjacent side wall panels 6122 respectively, at least two sides of the bracket 651 can be supported, so as to support the bracket 651 more stably.

[0178] In some embodiments, the support 652 includes a connecting portion 6521 and a supporting portion 6522. The connecting portion 6521 is connected to the side wall plate 6122 of the second housing 612, and the supporting portion 6522 extends from the connecting portion 6521 in a direction away from the corresponding side wall plate 6122. The bracket 651 is fixedly connected to the supporting portion 6522.

[0179] The connecting part 6521 refers to the structural part on the support 652 used to connect with the side wall panel 6122. The connecting part 6521 allows for connection with the side wall panel 6122, facilitating assembly. The shape of the connecting part 6521 is adapted to the shape of the corresponding area on the side wall panel 6122 to facilitate connection.

[0180] The support portion 6522 refers to the part of the structure on the support 652 used to support the bracket 651. The support portion 6522 is provided to facilitate the connection of the bracket 651. The support portion 6522 can be provided in the form of a plate to reduce the height occupied along the direction from the first housing 611 to the second housing 612.

[0181] Through the above technical solution, a connecting part 6521 is provided to facilitate connection with the side wall plate 6122 of the second housing 612, thereby fixing the support 652 to the second housing 612; the support part 6522 extends out from the connecting part 6521 to connect with the bracket 651, thereby fixing the bracket 651 to the second housing 612.

[0182] In some embodiments, the connecting part 6521 is welded to the side wall plate 6122. If the connecting part 6521 and the side wall plate 6122 are connected by welding methods such as laser welding or argon arc welding, the welding strength is high and aesthetically pleasing, ensuring the stability and reliability of the overall structure.

[0183] Welding the connecting part 6521 to the side wall plate 6122 makes the connection convenient and can also make the connecting part 6521 and the side wall plate 6122 firmly connected, thus improving the connection strength.

[0184] In some embodiments, the connecting part 6521 may also be connected by fasteners such as bolts and rivets.

[0185] In some embodiments, the support 6522 and the bracket 651 are fixedly connected by a first fastener 671.

[0186] The first fastener 671 can be a bolt, rivet, or other fastener.
