Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery device and an electrical appliance. Background Technology

[0002] In battery management systems, the real-time acquisition and reliable transmission of state parameters such as voltage and temperature of individual battery cells are crucial for battery state estimation, safety monitoring, and lifespan management.

[0003] In battery management systems, different functional components are typically arranged inside and outside the housing for functional layout purposes. Electrical connections between these components are mostly established using wiring harnesses. This connection method presents reliability risks during long-term operation. Utility Model Content

[0004] In view of the above problems, this application provides a battery device and an electrical device that can help improve the reliability of communication equipment during long-term operation.

[0005] In a first aspect, this application provides a battery device, which includes a battery cell and an electronic control device connected together. The electronic control device includes a first housing, a data processing component, and a wireless communication component. The first housing includes a through hole penetrating the wall of the first housing. The data processing component is disposed inside the first housing and includes a first processing unit and a first connector, the first connector being plugged into the first processing unit. The wireless communication component is disposed outside the first housing and includes a second processing unit and a second connector, the second connector being plugged into the second processing unit. Along the axial direction of the through hole, the first connector and the second connector are disposed opposite to each other, at least one of the first connector and the second connector passing through the through hole, and the first connector and the second connector being plugged into each other.

[0006] In some embodiments of the first aspect, the data processing component and the wireless communication component are electrically connected via a direct plug-in connection of the first connector and the second connector. This reduces the number of contact points along the entire signal link. Under conditions of continuous vibration from vehicle operation and significant changes in external ambient temperature, the contact points of the first connector and the second connector can maintain stable pressure contact, reducing the probability of communication interruption caused by contact loosening or oxidation, thereby improving the long-term operational reliability of the battery data acquisition and transmission link.

[0007] In some embodiments, the second connector passes through the communication hole, and one end of the second connector away from the second processing unit extends into the first housing and is inserted into the first connector along the axial direction of the communication hole.

[0008] In the above technical solution, during assembly, the second connector can be aligned with the connecting hole and pushed in until it is properly inserted with the first connector inside the first housing. The entire installation process is performed outside the first housing, reducing the number of alignment and insertion steps required in the confined space inside the first housing, thus improving assembly convenience.

[0009] In some embodiments, the surface of the second connector is provided with an insulating layer, which at least covers the area of ​​the second connector located within the communication hole.

[0010] In the above technical solution, this insulating layer physically isolates the conductive body of the second connector from the inner wall of the connecting hole, reducing the risk of short circuits or signal crosstalk caused by accidental contact between the second connector and the hole wall under vibration conditions. Simultaneously, the insulating layer improves the compatibility of the through-hole structure with the metal housing material, allowing for a wider range of material selection for the first housing.

[0011] In some embodiments, the first housing includes a first wall portion, a through hole penetrating the first wall portion, a first processing unit fixed to the first wall portion and located on the side of the first wall portion facing the interior of the first housing, and a second processing unit fixed to the first wall portion and located on the side of the first wall portion facing away from the interior of the first housing.

[0012] In the above technical solution, the housing wall simultaneously serves as the mounting base for both components, improving structural integration. Simultaneously, the first wall, as a shared structural component, reduces the need for additional mounting brackets or adapter structures, decreasing the number of parts and contributing to a lighter overall structure.

[0013] In some embodiments, the wireless communication component further includes a second housing and a seal, a second processing unit is disposed within the second housing, a second connector extends from within the second housing to outside the second housing, a seal is disposed on the periphery of the second connector, and a seal is provided between the second housing and the first wall portion.

[0014] In the above technical solution, the sealing element is placed between the second housing and the first wall and surrounds the periphery of the second connector. Sealing is achieved by the clamping force when the two housings are pressed together. The compression and positioning of the sealing element are completed simultaneously during installation, reducing the need for additional application of sealant or separate assembly of the sealing plug, thus improving assembly efficiency. Furthermore, the sealing element is protected by the two housings, making it less prone to detachment or displacement during long-term use, resulting in good sealing durability.

[0015] In some embodiments, the electronic control device further includes an adapter disposed between the second housing and the first wall portion, the second housing and the first wall portion being connected via the adapter, the adapter having a clearance hole, and at least a portion of the seal being located within the clearance hole.

[0016] In the above technical solution, the seal is housed within the clearance hole. The wall of the clearance hole acts as a circumferential limit for the seal, reducing the risk of outward displacement or extrusion under pressure and improving seal stability. Simultaneously, a portion of the seal's height is recessed into the clearance hole, allowing the mating surfaces between the adapter and the second housing to be closer, which helps reduce the overall thickness and improve structural compactness. Furthermore, the adapter itself can serve as a transitional part to accommodate different housing shapes. By replacing adapters of different thicknesses or adjusting the depth of the clearance hole, it can adapt to different seal compression requirements, improving structural versatility and design flexibility.

[0017] In some embodiments, the adapter and the first wall portion are an integral structure.

[0018] In the above technical solution, the adapter and the first wall are combined into a single integral part, eliminating the separate connection and assembly processes between the adapter and the first wall, further reducing the total number of parts. Simultaneously, by eliminating the mating surfaces between the adapter and the first wall, the assembly gap between them is eliminated. In long-term use, reducing one part interface also means reducing the risk of gaps arising from vibration loosening or wear of the mating surfaces, further improving the overall durability of the structure.

[0019] In some embodiments, the second housing has a groove on the side facing the first wall, and at least a portion of the seal is located within the groove.

[0020] In the above technical solution, the seal is constrained by the groove wall, making it less prone to slipping or shifting outwards under pressure, which helps improve the positioning accuracy of the seal during assembly. Simultaneously, the partial height of the seal is recessed into the groove, allowing the contact surfaces between the second housing and the first wall to be closer, reducing the risk of loosening due to gaps between the contact surfaces.

[0021] In some embodiments, a connecting protrusion is provided on the side surface of the first wall portion facing away from the interior of the first housing, and a mounting hole is provided on the side surface of the first wall portion facing the interior of the first housing. The mounting hole is recessed into the connecting protrusion, and the first processing unit is fixedly connected to the first wall portion through the mounting hole.

[0022] In the above technical solution, the mounting hole does not penetrate the first wall portion, and the outer surface of the first wall portion remains completely sealed outside the area covered by the connecting protrusion. The isolation function of the first housing wall portion is not compromised by the opening of the mounting hole, reducing the risk of moisture or dust being introduced from the mounting hole. At the same time, the connecting protrusion, as a local reinforcing structure, helps to improve the fixing reliability of the first processing unit.

[0023] In some embodiments, the battery device includes a housing, with individual battery cells disposed inside the housing and an electronic control device disposed outside the housing.

[0024] In the above technical solution, the above settings help to reduce the space occupied by the electronic control device in the cabinet, thereby improving energy utilization.

[0025] Secondly, this application provides an electrical device that includes a battery device as described in any of the preceding second aspects.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0032] In this application, the reference to "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 in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0035] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0036] In this application, "multiple" means two or more (including two).

[0037] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery device applications, market demand is also constantly increasing.

[0038] 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.

[0039] 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.

[0040] In battery management systems, functional components that perform different functions (such as collecting voltage and temperature data) are typically integrated into the high-voltage box, while some functional components (such as antennas) are integrated outside the high-voltage box. When establishing electrical connections between the functional components inside and outside the high-voltage box, wiring harnesses are mostly used. These wiring harnesses occupy internal space, increase system weight, and hinder further improvements in energy density. Furthermore, under long-term vibration and temperature changes, the risk of connection failure accumulates, thus threatening the long-term reliability of battery data acquisition and transmission.

[0041] To address the aforementioned technical issues, this application provides a battery device comprising a data processing component and a wireless communication component, which are electrically connected via a direct connection of a first connector and a second connector. This reduces the number of contact points along the entire signal link. Under conditions of continuous vibration from vehicle operation and significant changes in external ambient temperature, the contact points of the first and second connectors can maintain stable pressure contact, reducing the probability of communication interruptions caused by loosening or oxidation of the contacts, thereby improving the long-term operational reliability of the battery data acquisition and transmission link.

[0042] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use battery cells and battery devices, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships and spacecraft, etc. For example, spacecraft include airplanes, rockets, space shuttles and spacecraft.

[0043] For ease of explanation, the following embodiments use a vehicle as an example of electrical equipment.

[0044] Figure 1 The diagram shows the structure of a vehicle provided in some embodiments of this application.

[0045] like Figure 1 As shown, a battery device 100 is provided inside the vehicle 1000. The battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle 1000; for example, the battery device 100 can serve as the operating power source for the vehicle 1000.

[0046] The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, for the power needs of the vehicle 1000 during startup, navigation and driving.

[0047] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0048] Figure 2 This is a schematic diagram of the structure of a battery device provided in some embodiments of this application.

[0049] like Figure 2 As shown, in some embodiments, the battery device 100 may be a battery pack, which includes a housing 100b and one or more battery cell assemblies 100a, the battery cell assemblies 100a being housed in the housing 100b.

[0050] As an example, the battery cell assembly 100a can be a battery module, and the battery cell assembly 100a can be housed in the housing 100b by fixing the battery module in the housing 100b.

[0051] As an example, the battery cell assembly 100a can also be housed in the housing 100b by directly fixing multiple battery cells to the housing 100b.

[0052] As an example, the housing 100b may include a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are fastened together to form a closed space inside the housing 100b to house the battery cell assembly 100a. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first housing 1 may be a top cover or a bottom plate.

[0053] As an example, the housing 100b may include a top cover, a frame, and a bottom plate. The top cover and the bottom plate are respectively connected to the frame, so that the interior of the housing 100b forms an enclosed space to house the battery cell assembly 100a.

[0054] As an example, the housing 100b can be part of the chassis structure of the vehicle 1000. For example, the top cover of the housing 100b can be at least part of the floor of the vehicle 1000, or the frame of the housing 100b can be at least part of the crossbeams and longitudinal beams of the vehicle 1000.

[0055] In some alternative embodiments, such as Figure 2 As shown, the battery device 100 also includes a housing 100b, with individual battery cells disposed inside the housing 100b and an electronic control device 400 disposed outside the housing 100b.

[0056] The electronic control device 400 is located outside the housing 100b. The wireless communication component 30 can be located on the side of the first housing 10 facing away from the housing 100b, or the wireless communication component 30 can be located on the surface of the first housing 10 adjacent to the housing 100b.

[0057] In this embodiment of the application, the above-mentioned arrangement helps to reduce the space occupied by the electronic control device in the housing, thereby improving energy utilization.

[0058] Figure 3 This is an isometric structural diagram of an electronic control device provided in some embodiments of this application. Figure 4 This is an isometric structural schematic diagram of an electronic control device provided in some embodiments of this application. Figure 5 This is an exploded structural diagram of an electronic control device provided in some embodiments of this application. Figure 6 This is a cross-sectional structural diagram of an electronic control device provided in some embodiments of this application. The first housing may include multiple walls, for ease of understanding. Figures 3 to 5 One of the walls in the first housing is not shown.

[0059] Please refer to the following: Figures 3 to 6 According to some embodiments of this application, this application provides a battery device 100, which includes a battery cell and an electronic control device 400 connected to each other. The electronic control device 400 includes a first housing 10, a data processing component 20, and a wireless communication component 30. The first housing 10 includes a through hole H1 penetrating the wall of the first housing 10. The data processing component 20 is disposed inside the first housing 10 and includes a first processing unit 21 and a first connector 22, which is plugged into the first processing unit 21. The wireless communication component 30 is disposed outside the first housing 10 and includes a second processing unit 31 and a second connector 32, which is plugged into the second processing unit 31. Along the axial direction of the through hole, the first connector 22 and the second connector 32 are arranged opposite to each other, and at least one of the first connector 22 and the second connector 32 passes through the through hole H1 and is plugged into each other.

[0060] The electronic control device 400 refers to a device capable of transmitting signals or data between two circuit components. For example, the electronic control device 400 can be a data acquisition and wireless transmission module in a battery management system, or it can be an in-vehicle communication terminal, etc. The battery cell and the electronic control device 400 can be electrically connected via conductive components to acquire information from the battery cell.

[0061] The first housing 10 refers to a structural component used to house and protect internal components. In a battery management system, it can be a metal or plastic casing of a high-voltage distribution box, a separate protective box, or a panel within the battery pack itself. For example, the first housing 10 has a receiving space. The data processing component 20 is located within the receiving space, and the wireless communication component 30 is located on the outer surface of the first housing 10.

[0062] The wall refers to the solid structure within the first housing 10 that forms the interface between its inner and outer parts. The wall's function is to physically separate the inner and outer spaces of the housing and to provide the structural basis for the opening of the connecting hole H1. The connecting hole H1 is a through opening extending from one side (inside the first housing 10) to the other side (outside the first housing 10) of the wall. Its size, cross-sectional shape, and location are not specifically limited. The cross-section can be circular, rectangular, oblong, or any other contour. The connecting hole H1 provides a physical channel through which connectors for internal and external components of the housing can pass.

[0063] Data processing component 20 refers to a collection of circuit units capable of signal acquisition, conversion, computation, or logic processing. Data processing component 20 can be a complete component consisting of a printed circuit board, control chip, sampling chip, memory, etc., or it can be a processing system composed of interconnected multiple daughter boards. Data processing component 20 can acquire the voltage and temperature of individual battery cells, execute equalization control algorithms, or perform communication protocol conversion, etc. Optionally, data processing component 20 can be an RDB (Remote Data Box).

[0064] The data processing component 20 includes a first processing unit 21 and a first connector 22. The first processing unit 21 refers to a circuit area or chip within the data processing component 20 that performs computation, control, or signal conditioning tasks. Optionally, the first processing unit 21 may include a microcontroller, a digital signal processor, or an analog front-end sampling chip, etc. The first connector 22 is an interface component fixed to the data processing component 20 for establishing an external electrical connection. Optionally, the first connector 22 may include an insulating base with conductive contacts, a contact piece formed by stamping and bending metal, or a contact array on the edge of a printed circuit board, etc. Optionally, the data processing component 20 also includes a first substrate 24, the first processing unit 21 is disposed on the first substrate 24, the first connector 22 is fixed to the first substrate 24, and the first connector 22 and the first processing unit 21 are electrically connected through circuitry within the first substrate 24.

[0065] The wireless communication component 30 may include an antenna unit. An antenna unit is a functional module capable of converting electrical signals into spatial electromagnetic waves for outward radiation, or receiving electromagnetic waves from external space and converting them into electrical signals. The antenna unit includes an antenna radiator and an impedance matching circuit. In this embodiment, the wireless communication component 30 is mounted outside the first housing 10 and is responsible for transmitting the battery status data processed by the data processing component 20 in the form of a wireless signal.

[0066] The wireless communication component 30 includes a second processing unit 31 and a second connector 32. The second processing unit 31 refers to the circuitry within the wireless communication component 30 that performs radio frequency signal processing. The second processing unit 31 can be an integrated radio frequency transceiver chip, a radio frequency front-end module, or an impedance matching network, etc. The second connector 32 corresponds to the first connector 22 and is fixed to the wireless communication component 30. The second connector 32 is the external electrical interface of the wireless communication component 30 and can cooperate with the first connector 22 on the data processing component 20 to achieve separable electrical and mechanical connections.

[0067] Along the axial direction of the connecting hole, the first connector 22 and the second connector 32 are arranged opposite to each other. In other words, the mating end faces of the first connector 22 and the second connector 32 are arranged opposite to each other in the axial direction. Here, "arranged opposite to each other" means that the mating end faces of the first connector 22 and the second connector 32 can contact each other inside the connecting hole H1, or at the edge of the opening of the connecting hole H1, or one connector can be inserted into the connecting hole H1 and the other can be received outside the connecting hole H1.

[0068] For example, at least one of the two components, the first connector 22 and the second connector 32, is inserted into and passes through the connecting hole H1 on the first housing 10. After insertion, the first connector 22 and the second connector 32 directly contact each other near the connecting hole H1, forming a conductive path. Thus, a complete signal transmission link is established between the data processing component 20 and the wireless communication component 30. Regarding the mating method of the first connector 22 and the second connector 32, a direct-insertion structure can be adopted. For example, the first connector 22 and the second connector 32 can be inserted along the axial direction of the connecting hole H1, simultaneously achieving mechanical fixation and circuit conduction. The first connector 22 and the second connector 32 can be a direct-insertion male terminal and a direct-insertion female terminal, respectively. Furthermore, the two connectors can have identical structures, with each connector integrating a resilient contact and a receiving pad on an insulating base, and the insulating base designed as a centrally symmetrical locking structure. The first connector 22 and the second connector 32 can be paired and inserted into each other.

[0069] In some examples, the first connector 22 passes through the connecting hole H1, and a portion of the first connector 22 passes through the connecting hole H1, and the first connector 22 and the second connector 32 are electrically connected; in other examples, the second connector 32 passes through the connecting hole H1, and a portion of the second connector 32 passes through the connecting hole H1, and the first connector 22 and the second connector 32 are electrically connected; in still other examples, both the first connector 22 and the second connector 32 pass through the connecting hole H1, and the first connector 22 and the second connector 32 can be electrically connected within the connecting hole H1.

[0070] In this embodiment, the data processing component 20 and the wireless communication component 30 are electrically connected through direct plugging of the first connector 22 and the second connector 32. This reduces the number of contact points along the entire signal link. Under conditions of continuous vibration from vehicle 1000 driving and significant changes in external ambient temperature, the contact points of the first and second connectors can maintain stable pressure contact, reducing the probability of communication interruption caused by loosening or oxidation of the contacts, thereby improving the long-term operational reliability of the battery data acquisition and transmission link.

[0071] In some alternative embodiments, please refer to Figure 5 and Figure 6 The second connector 32 passes through the connecting hole H1. The end of the second connector 32 away from the second processing unit 31 extends into the first housing 10 and is inserted into the first connector 22 along the axial direction of the connecting hole H1.

[0072] For example, the second connector 32 is fixed to the wireless communication unit and electrically connected to the second processing unit 31 inside the wireless communication unit. The main body of the second connector 32 extends outward from the wireless communication unit, and its end away from the second processing unit 31 passes through the communication hole H1 on the wall of the first housing 10 and extends into the housing from the outside of the housing.

[0073] Inside the housing, the protruding end of the second connector 32 mates with the end of the first connector 22 on the data processing assembly 20. "Meeting with each other" here refers to the mating method where the two ends approach each other face-to-face during the insertion process. Specifically, the end of the first connector 22 faces the connecting hole H1, and the protruding end of the second connector 32, after entering through the connecting hole H1, also faces the first connector 22; the two end faces are spatially aligned. During assembly, the second connector 32 is pushed along the axial direction of the connecting hole H1, and the two end faces gradually approach each other until the contact surfaces of the ends interlock and press together, thereby forming a stable electrical connection.

[0074] The two connectors are inserted into each other along the axial direction of the connecting hole H1, and the conductive contacts on the connectors achieve electrical conduction through pressure contact.

[0075] This "outside-in, inside-the-casing" layout allows the wireless communication unit to be aligned with the second connector 32 and pushed into the connecting hole H1 during assembly, until it is properly inserted into the first connector 22 inside the first casing 10. The entire installation process is performed outside the first casing 10, reducing the need for alignment and insertion within the confined space inside the first casing 10, thus improving assembly convenience.

[0076] Figure 7 This is a cross-sectional structural diagram of a wireless communication component in an electronic control device provided in some embodiments of this application.

[0077] In some alternative embodiments, please refer to Figure 5 and Figure 7 The surface of the second connector 32 is provided with an insulating layer 34, which at least covers the area of ​​the second connector 32 located within the connecting hole H1.

[0078] For example, when the second connector 32 passes through the communication hole H1 of the first housing 10, the distance between the outer surface of the second connector 32 and the inner wall of the communication hole H1 is relatively small. If the first housing 10 is made of metal, or if the inner wall of the communication hole H1 is conductive, the second connector 32 may come into contact with the hole wall during insertion or long-term use, forming an unexpected conductive path and affecting the signal transmission quality.

[0079] Therefore, in this embodiment, an insulating layer 34 is provided on the surface of the second connector 32. The insulating layer 34 at least covers the area of ​​the second connector 32 located within the connecting hole H1. That is, the outer peripheral surface of the second connector 32 is wrapped with insulating material along the length of the section passing through the wall thickness of the connecting hole H1. The material of the insulating layer 34 may include polyimide film, fluoroplastic coating, heat shrink tubing, or injection molding, etc.

[0080] In this embodiment, the insulating layer 34 physically isolates the conductive body of the second connector 32 from the inner wall of the connecting hole H1, reducing the risk of short circuits or signal crosstalk caused by accidental contact between the second connector 32 and the hole wall under vibration conditions. Simultaneously, the insulating layer 34 improves the compatibility of the through-hole structure with the metal housing material, allowing for a wider range of material choices for the first housing 10.

[0081] Optionally, the insulating layer 34 may also extend to both sides of the connecting hole H1 to cover a portion of the second connector 32 adjacent to the inlet and outlet of the connecting hole H1, in order to improve insulation reliability.

[0082] In some alternative embodiments, please continue to refer to Figure 5 and Figure 6 The first housing 10 includes a first wall portion 11, a connecting hole H1 passing through the first wall portion 11, a first processing unit 21 fixed to the first wall portion 11 and located on the side of the first wall portion 11 facing the inside of the first housing 10, and a second processing unit 31 fixed to the first wall portion 11 and located on the side of the first wall portion 11 facing away from the inside of the first housing 10.

[0083] In some examples, the first housing 10 has a first wall portion 11. The first wall portion 11 is a wall panel area of ​​the first housing 10, and the first wall portion 11 can be the bottom wall, side wall, or top wall of the first housing 10. The first wall portion 11 serves as the mounting base for the two components inside and outside the first housing 10. A connecting hole H1 is formed through the first wall portion 11, that is, it penetrates from the side of the first wall portion 11 facing the inside of the housing to the side facing away from the inside of the housing, forming a channel that runs through the internal and external spaces.

[0084] The first processing unit 21 of the data processing component 20 is fixed to the first wall portion 11 and located on the side surface of the first wall portion 11 facing the interior of the first housing 10. That is, the first wall portion 11 has a mounting structure for connecting to the data processing component 20, so that the first processing unit 21 is directly or indirectly fixed to the first wall portion 11. The second processing unit 31 of the wireless communication unit is fixed to the first wall portion 11 and located on the side surface of the first wall portion 11 facing away from the interior of the first housing 10. That is, the first wall portion 11 has a mounting structure for connecting to the wireless communication component 30, so that the second processing unit 31 is directly or indirectly fixed to the first wall portion 11. This allows the first processing unit 21 and the second processing unit 31 to be respectively attached to opposite sides of the first wall portion 11, forming a back-to-back arrangement. A connecting hole H1 passes between them, and the first connector 22 and the second connector 32 are connected and aligned through the connecting hole H1.

[0085] Optionally, the first processing unit 21 can be directly fixed to the first wall portion 11. Of course, the data processing assembly 20 may also include a third housing 23, in which the first processing unit 21 is disposed, and the first processing unit 21 is fixed to the first housing 10 through the third housing 23.

[0086] Optionally, the second processing unit 31 can be directly fixed to the first wall portion 11. Of course, the wireless communication component 30 may also include a second housing 33, in which the second processing unit 31 is disposed, and the second processing unit 31 is fixed to the first housing 10 through the second housing 33.

[0087] In this embodiment, the housing wall simultaneously serves as the mounting base for both components, improving structural integration. Furthermore, the first wall 11, as a shared structural component, reduces the need for additional mounting brackets or adapter structures, decreasing the number of parts and contributing to overall structural weight reduction.

[0088] Figure 8 This is an isometric structural diagram of the wireless communication component in an electronic control device provided in some embodiments of this application.

[0089] In some alternative embodiments, please refer to Figures 6 to 8The wireless communication component 30 also includes a second housing 33 and a seal 35. The second processing unit 31 is disposed inside the second housing 33. The second connector 32 extends from inside the second housing 33 to outside the second housing 33. The seal 35 is disposed on the periphery of the second connector 32. The seal 35 is provided between the second housing 33 and the first wall portion 11.

[0090] Exemplarily, the second housing 33 includes an accommodating space, within which the second processing unit 31 is disposed. One end of the second connector 32 is electrically connected to the second processing unit 31 inside the second housing 33, and the other end extends outward from the wall of the second housing 33 to the outside of the second housing 33, for passing through the communicating hole H1 on the first housing 10 and engaging with the first connector 22 inside. Optionally, the second housing 33 may include a first housing portion 331 and a second housing portion 332, which together form the accommodating space. The first housing portion 331 may be located on the side of the second housing portion 332 facing away from the first wall portion 11, and the second processing unit 31 may be fixed to the second housing portion 332. A sealing member 35 may be disposed between the second housing portion 332 and the first wall portion 11.

[0091] The sealing element 35 is disposed on the outer peripheral side of the second connector 32. When the wireless communication unit is assembled to the first wall portion 11, the second housing 33 is pressed against the first wall portion 11, and the sealing element 35 is sandwiched between the outer surface of the second housing 33 and the surface of the first wall portion 11, and undergoes elastic deformation under the action of the clamping force to fill the gap between them. Optionally, the sealing element 35 and the second connector 32 can be disposed at intervals, that is, the orthographic projection of the sealing element 35 on the first wall surface is located on the periphery of the orthographic projection outline of the connecting hole H1 on the first wall surface, and the sealing element 35 and the connecting hole H1 are disposed at intervals; or, the sealing element 35 is disposed around the peripheral surface of the second connector 32. When the sealing element 35 is disposed around the peripheral surface of the second connector 32, the end of the second connector 32 away from the second housing 33 protrudes from the surface of the sealing element 35 facing away from the second housing 33, that is, a part of the sealing element 35 can fill the connecting hole H1, and another part is disposed between the first housing 10 and the second housing 33.

[0092] The seal 35 is positioned around the root of the second connector 32 that protrudes from the second housing 33, so that the mating surface between the second housing 33 and the first wall portion 11 is sealed by the seal 35. External moisture and dust are blocked from entering along the mating surface, reducing the risk of moisture or dust accumulation in the space where the internal data processing component 20 is located due to insufficient sealing.

[0093] In this embodiment, the sealing element 35 is disposed between the second housing 33 and the first wall portion 11 and surrounds the periphery of the second connector 32. Sealing is achieved using the clamping force when the two housings are pressed together. The compression and positioning of the sealing element 35 is completed simultaneously during installation, reducing the need for additional application of sealant or separate assembly of the sealing plug, thus improving assembly efficiency. Simultaneously, the sealing element 35 is protected by the two housings, making it less prone to detachment or displacement during long-term use, resulting in good sealing durability.

[0094] In some alternative embodiments, please continue to refer to Figure 5 and Figure 6 The electronic control device 400 also includes an adapter 40, which is disposed between the second housing 33 and the first wall portion 11. The second housing 33 and the first wall portion 11 are connected through the adapter 40. The adapter 40 is provided with a clearance hole H3, and at least a portion of the seal 35 is located in the clearance hole H3.

[0095] The adapter 40 is disposed between the second housing 33 and the first wall portion 11. One side of the adapter 40 is attached to and fixed to the surface of the first wall portion 11, and the other side is connected to the second housing 33, thereby establishing a mechanical connection between the second housing 33 and the first wall portion 11. Optionally, the adapter 40 can be a plate-shaped structural component.

[0096] The adapter 40 has a clearance hole H3. The orthographic projection of the seal 35 onto the first wall portion 11 lies within the orthographic projection of the clearance hole H3 onto the first wall portion 11, and the orthographic projection outline of the connecting hole H1 onto the first wall portion 11 lies within the orthographic projection of the clearance hole H3 onto the first wall portion 11. After assembly, at least a portion of the seal 35 is accommodated within the clearance hole H3.

[0097] Optionally, the adapter 40 may be provided with a second fastener 60, and the second housing 33 may be connected to the adapter 40 through the second fastener 60.

[0098] In this embodiment, the seal 35 is housed within the clearance hole H3. The wall of the clearance hole H3 provides circumferential restraint for the seal 35, reducing the risk of outward displacement or extrusion of the seal 35 under pressure and improving sealing stability. Simultaneously, a portion of the seal 35's height is recessed into the clearance hole H3, allowing the mating surfaces between the adapter 40 and the second housing 33 to be closer, which helps reduce the overall thickness and improve structural compactness. Furthermore, the adapter 40 itself can serve as a transitional part adaptable to different housing shapes. By replacing the adapter 40 with different thicknesses or adjusting the depth of the clearance hole H3, it can accommodate different specifications of seal 35 compression, improving structural versatility and design flexibility.

[0099] In some alternative embodiments, the adapter 40 and the first wall portion 11 are integrally formed.

[0100] In this embodiment, the adapter 40 and the first wall portion 11 are combined into a single integral part, eliminating the separate connection and assembly processes between the adapter 40 and the first wall portion 11, further reducing the total number of parts. Simultaneously, by eliminating the mating surfaces between the adapter 40 and the first wall portion 11, the assembly gap between them is eliminated. In long-term use, reducing one part interface also means reducing the risk of gaps arising from vibration loosening or wear of the mating surfaces, further improving the overall durability of the structure.

[0101] Figure 9 This is a cross-sectional structural diagram of a wireless communication component in an electronic control device provided in some embodiments of this application.

[0102] In some alternative embodiments, please refer to Figure 9 The second housing 33 has a groove 33a on the side facing the first wall 11, and at least a portion of the seal 35 is located in the groove 33a.

[0103] A groove 33a is formed on the surface of the second housing 33 facing the first wall portion 11. The groove 33a is located around the root of the second connector 32 that protrudes from the second housing 33. The seal 35 is fitted around the periphery of the second connector 32, and the groove 33a accommodates at least a portion of the seal 35. Optionally, the groove 33a can accommodate the entire structure of the seal 35, that is, the surface of the seal 35 away from the bottom of the groove 33a is coplanar with the surface of the second housing 33 facing the first wall portion 11; or, the groove 33a can accommodate a portion of the structure of the seal 35, and another portion of the structure protrudes from the surface of the second housing 33 facing the first wall portion 11.

[0104] In this embodiment, the seal 35 is constrained by the groove wall of the groove 33a, making it less prone to slipping or shifting outwards under pressure, which helps improve the positioning accuracy of the seal 35 during assembly. Simultaneously, a portion of the seal 35 is recessed into the groove 33a, allowing the mating surfaces between the second housing 33 and the first wall 11 to be closer together, reducing the risk of loosening due to gaps between the mating surfaces.

[0105] Figure 10 This is a cross-sectional structural schematic diagram of an electronic control device provided in some embodiments of this application.

[0106] In some alternative embodiments, please refer to Figure 5 and Figure 10The first wall portion 11 has a connecting protrusion 12 on the side surface facing away from the interior of the first housing 10, and a mounting hole H2 on the side surface facing the interior of the first housing 10. The mounting hole H2 is recessed into the connecting protrusion 12, and the first processing unit 21 is fixedly connected to the first wall portion 11 through the mounting hole H2.

[0107] The connecting protrusion 12 refers to a solid structure that protrudes outward from the surface of the first wall portion 11 facing away from the interior of the first housing 10. The connecting protrusion 12 is an integral structure with the first wall portion 11. The connecting protrusion 12 provides an additional solid thickness as a screw-in length for the first fastener 50 driven into the interior of the first housing 10, thereby achieving reliable threaded fastening without penetrating the wall portion.

[0108] Mounting hole H2 is used for screwing in the first fastener 50 to secure the first processing unit 21. Mounting hole H2 is formed on the side surface of the first wall portion 11 facing the interior of the housing, recessed inward and extending into the interior of the connecting protrusion 12. That is, mounting hole H2 is a blind hole structure.

[0109] Optionally, the number of connecting protrusions 12 may include one or more. For example, when the connecting protrusion 12 is a columnar structure, the number of connecting protrusions 12 is multiple, and each of the multiple connecting protrusions 12 is provided with a mounting hole H2 corresponding to its number in a one-to-one manner; when the connecting protrusion 12 is an annular protrusion, the number of connecting protrusions 12 may be one or more, and one connecting protrusion 12 may be provided with multiple spaced mounting holes H2.

[0110] In some examples, the first processing unit 21 (or the third housing 23) is locked to the inner surface of the first wall portion 11 by engaging the mounting hole H2 with a first fastener 50. The first fastener 50 may be, for example, a screw that passes through a mounting through-hole on the circuit board of the first processing unit 21 (or the third housing 23) and is screwed into the mounting hole H2, with sufficient thread engagement length obtained by relying on the additional wall thickness provided by the connecting protrusion 12.

[0111] In this embodiment, the mounting hole H2 does not penetrate the first wall portion 11, and the outer surface of the first wall portion 11 remains completely sealed outside the area covered by the connecting protrusion 12. The isolation function of the wall portion of the first housing 10 is not compromised by the opening of the fixing hole, reducing the risk of moisture or dust being introduced from the fixing hole. At the same time, the connecting protrusion 12, as a local reinforcement structure, helps to improve the fixing reliability of the first processing unit 21.
