[0002] With the improvement of people's living standards, cars have gradually become an essential means of transportation for most families. Among them, with the continuous development of vehicle electrification, electric vehicles have gradually become the first choice of users.

[0003] As electric vehicles become increasingly intelligent, the number of electrical devices in them is also increasing. Generally, these devices use cables for power supply and data transmission, which results in an increasing number of cables in electric vehicles.

[0004] Because the quality of cables is difficult to control during production and installation, the cables connecting electrical devices in electric vehicles are prone to failure, which in turn leads to malfunctions in corresponding functions of the electric vehicle, increasing the overall failure rate of the electric vehicle and affecting the user experience. Summary of the Invention

[0005] The purpose of the present application is to provide a vehicle and a vehicle detection method for solving the problem that existing vehicles are prone to malfunction of some vehicle functions due to cable failure.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, an embodiment of the present application provides a vehicle comprising multiple electrical systems and multiple circuit board assemblies. The multiple circuit board assemblies are electrically connected to the multiple electrical systems, and the multiple electrical systems are electrically connected via the multiple circuit board assemblies. The circuit board assembly includes multiple first circuit boards and a connecting busbar. The multiple first circuit boards define a storage space with openings at both ends. The connecting busbar is connected to the first circuit boards and is located outside the storage space defined by the multiple first circuit boards.

[0008] According to the above-mentioned technical means, the vehicle provided by the embodiment of the present application, since multiple circuit board assemblies are electrically connected to multiple electrical systems, multiple electrical systems can be electrically connected through multiple circuit board assemblies. In this way, the electrical connection of multiple electrical systems is directly achieved by using the circuit board assembly, without the need to use cables for connection, thereby avoiding the problem of partial functional failure of the vehicle caused by the easy failure of cables, and improving the performance of the vehicle. In addition, multiple first circuit boards can form a three-dimensional space structure, which can effectively utilize the three-dimensional space, making it more convenient to install. By setting a connecting busbar, when the large current that needs to be transmitted by the electrical connection of the electrical system cannot be circulated through the first circuit board, the connecting busbar can be connected to the electrical system, and the connecting busbar is used to circulate a larger current.

[0009] In a possible implementation, the circuit board assembly further includes at least one second circuit board. The second circuit board is located in the accommodation space and connected to the first circuit board.

[0010] According to the above technical means, since the second circuit board is arranged in the accommodation space formed by the plurality of first circuit boards, further space can be saved and installation is made more convenient. At the same time, by providing the second circuit board, the circuit board assembly can make more electrical connections.

[0011] In a possible implementation, the vehicle further includes a connecting pipeline, which is arranged in the accommodating space.

[0012] According to the above technical means, the connecting pipeline can be arranged in the accommodation space formed by the multiple first circuit boards, thereby realizing reasonable use of the space.

[0013] In a possible implementation, the vehicle further includes a connecting cable, which is passed through the accommodating space.

[0014] According to the above technical means, when some electrical connection lines of the electrical system cannot be connected through the circuit board, they can be connected using connecting cables. At the same time, since the connecting cables can be placed in the accommodation space, the space can also be reasonably utilized.

[0015] In a possible embodiment, the vehicle further includes a filling material, and the filling material is filled in the accommodating space.

[0016] According to the above technical means, by providing the filling material, the connecting cables or connecting pipes located in the accommodating space can be kept stable and prevented from shaking back and forth.

[0017] In one possible embodiment, the circuit board assembly further includes a housing, an installation space is formed inside the housing, and the plurality of first circuit boards are located in the installation space.

[0018] According to the above technical means, by providing a shell, the first circuit board can be arranged inside the shell, which plays a role in protecting the first circuit board and preventing the first circuit board from being directly impacted by the outside.

[0019] In one possible embodiment, the housing is formed with a snap-in groove. The vehicle further includes a body. The body includes a beam structure. A portion of the beam structure is snap-into the snap-in groove and connected to the housing.

[0020] According to the above technical means, the circuit board assembly can also be installed on the beam structure through the snap-fit ​​groove formed in the shell, and the installation is simple, convenient and easy to implement.

[0021] In a possible embodiment, the vehicle further includes a plurality of temperature sensors, which are disposed on the plurality of circuit board assemblies and are used to detect the temperature of the circuit board assemblies.

[0022] According to the above technical means, the temperature of the circuit board assembly can be detected by multiple temperature sensors. When the temperature of the circuit board assembly is too high, the temperature sensor can be used to detect it in time to avoid safety hazards.

[0023] In a second aspect, an embodiment of the present application provides a vehicle detection method, comprising the steps of detecting the temperatures of multiple circuit board assemblies and determining whether the temperatures of the multiple circuit board assemblies are abnormal. Detecting the temperatures of the multiple circuit board assemblies includes detecting the temperatures of multiple first circuit boards, where the highest temperature among the multiple first circuit boards is the temperature of the circuit board assembly.

[0024] According to the above technical means, by determining whether the temperature of the circuit board assembly is abnormal, it is possible to determine whether the circuit board assembly has failed, thereby avoiding the occurrence of safety hazards.

[0025] In one possible embodiment, after detecting the temperatures of the multiple circuit board assemblies, the vehicle detection method further includes: sequentially comparing the temperatures of the multiple circuit board assemblies in pairs to obtain multiple sets of temperature difference values. Determining whether the temperatures of the multiple circuit board assemblies are abnormal includes: comparing the multiple sets of temperature difference values ​​with preset temperature difference values. If the temperature difference is greater than the preset temperature difference, the temperature of the circuit board assembly is abnormal.

[0026] According to the above technical means, by comparing the temperature differences between the circuit board assemblies, if the temperature difference between the circuit board assemblies is too high and greater than the preset temperature difference, it can be determined that one of the two groups of circuit board assemblies has a higher temperature, and the circuit board assembly may have failed.

[0027] In a possible implementation, determining whether the temperatures of the plurality of circuit board assemblies are abnormal includes comparing the temperatures of the plurality of circuit board assemblies with a preset temperature; if the temperatures of the circuit board assemblies are greater than the preset temperature, the temperatures of the circuit board assemblies are abnormal.

[0028] According to the above technical means, by directly comparing the temperature of the circuit board assembly with the preset temperature, when the temperature of the circuit board assembly is too high and greater than the preset temperature, it can be determined that the circuit board assembly has a high temperature and the circuit board assembly may fail.

DETAILED DESCRIPTION

[0046] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0048] Based on this, the present invention provides a vehicle. The present invention does not specifically limit the specific type of vehicle. For example, the vehicle provided in the present invention can be an electric vehicle, a hybrid vehicle, or a solar vehicle.

[0049] like Figure 1 As shown, the vehicle 100 provided in an embodiment of the present application may include a vehicle body 10. The vehicle body 10 may include a vehicle frame, doors, and windows. The vehicle frame may form the overall exterior shape of the vehicle 100 and a passenger compartment. The doors may be rotatably connected to the vehicle frame to open or close the interior passenger compartment. Windows may be mounted on the doors or the vehicle frame to facilitate passengers' observation of the external environment.

[0050] Furthermore, to enable the basic functions of vehicle 100, vehicle 100 may also include multiple electrical systems. These electrical systems may be powered by electricity. It will be appreciated that the specific type of electrical system can be selected based on actual circumstances. For example, the multiple electrical systems may include systems requiring power and data transmission, such as a cabin system, a battery management system, and an intelligent driving system. Furthermore, the electrical system may also, for example, include components such as a drive system and a powertrain system.

[0051] The drive system can drive the wheels to rotate. Depending on the driving mode of the drive system, the drive system can be divided into front-wheel drive, rear-wheel drive and four-wheel drive arrangements.

[0052] The power system can provide power to the vehicle 100, enabling the vehicle 100 to complete basic driving functions. The composition of the power system varies depending on the type of vehicle 100. For example, when the vehicle 100 is an electric vehicle, the power system can include an electric motor.

[0053] In order to realize the circuit connection between multiple electrical systems, such as Figure 1 As shown, the vehicle 100 provided in the embodiment of the present application may further include a circuit board assembly 20. Multiple circuit board assemblies 20 may be electrically connected to multiple electrical systems. Multiple electrical systems may be electrically connected via multiple circuit board assemblies 20. Thus, the electrical systems may be electrically connected via the circuit board assemblies 20, and the circuit board assemblies 20 may implement functions such as power supply and data transmission for the electrical systems.

[0054] It is understandable that the electrical connection relationship between the multiple electrical systems can be designed according to actual conditions. For example, the battery management system in the electrical system can be electrically connected to the power battery through the circuit board assembly 20.

[0055] Thus, in the vehicle 100 provided by the embodiment of the present application, since the multiple circuit board assemblies 20 are electrically connected to the multiple electrical systems, the multiple electrical systems can be electrically connected through the multiple circuit board assemblies 20. In this way, the electrical connection of the multiple electrical systems is achieved directly through the circuit board assemblies 20, without the need for cables. This avoids the problem of partial functional failure of the vehicle 100 caused by cable failure, thereby improving the performance of the vehicle 100.

[0056] Furthermore, because multiple electrical systems are electrically connected via multiple circuit board assemblies 20, the circuit board assemblies 20 can be directly industrialized and automated using equipment, improving production efficiency and avoiding quality issues associated with manual production. Furthermore, compared to cables, the circuit board assemblies 20 are more regular and compact, saving installation space and creating a neater, more tidy structure.

[0057] For example, in order to achieve electrical connection between the circuit board assembly 20 and the electrical system, a socket may be designed on the circuit board assembly 20. The circuit board assembly 20 and the electrical system may be electrically connected by plugging.

[0058] It is understood that the circuit board assembly 20 can be arranged at different locations of the vehicle 100 to facilitate its connection with the electrical system. Figure 1 and Figure 2 As shown, the circuit board assembly 20 can be installed at various positions of the vehicle body 10 to form a basic frame structure of the entire vehicle, so that the electrical systems set at various positions can be electrically connected to the surrounding circuit board assemblies 20.

[0059] In some embodiments, as Figure 3 As shown, the circuit board assembly 20 may include a plurality of first circuit boards 21. The plurality of first circuit boards 21 form a receiving space with openings at both ends. In this way, the plurality of first circuit boards 21 can form a three-dimensional spatial structure, which can effectively utilize the three-dimensional space and make installation more convenient.

[0060] It is understandable that the number of the first circuit boards 21 can be designed according to actual conditions. Figure 3 As shown, the number of first circuit boards 21 can be four. The four first circuit boards 21 together form a square space area. Of course, the number of first circuit boards 21 can also be other. For example, the number of first circuit boards 21 can also be three or five.

[0061] Of course, when the circuit board assembly 20 needs to connect fewer electrical systems, in other embodiments, the circuit board assembly 20 may also include only one first circuit board 21. In this case, the single first circuit board 21 can complete the connection between the electrical systems.

[0062] In some embodiments, as Figure 4 As shown, the circuit board assembly 20 also includes a connecting busbar 22. The connecting busbar 22 is connected to the first circuit board 21 and is located outside the accommodation space surrounded by the multiple first circuit boards 21. The provision of the connecting busbar 22 allows the connection to the electrical system when the high current required to be transmitted by the electrical connection of the electrical system cannot flow through the first circuit board 21, thereby utilizing the connecting busbar 22 to carry the higher current.

[0063] For example, the connecting busbar 22 can be used to connect the redundant power supply in the intelligent driving system, the redundant power supply in the wire-controlled chassis system, or high-power devices such as pedals.

[0064] It is understood that the connecting busbar 22 can be made of metal material. Exemplarily, the connecting busbar 22 can be made of metal copper or aluminum. Of course, the connecting busbar 22 can also be made of other metal materials as long as it can achieve the conductive function.

[0065] Furthermore, in some embodiments, there may be multiple busbars 22. This allows for multiple electrical connections to be made through multiple busbars 22, making the connection more efficient. Of course, in other embodiments, there may be only one busbar 22, which can be designed based on actual conditions.

[0066] In some embodiments, as Figure 5 As shown, the circuit board assembly 20 also includes at least one second circuit board 23. The second circuit board 23 is located within the accommodation space and is connected to the first circuit board 21. This arrangement of the second circuit board 23 within the accommodation space formed by the plurality of first circuit boards 21 further saves space and facilitates installation. Furthermore, the provision of the second circuit board 23 allows the circuit board assembly 20 to make more electrical connections.

[0067] For example, Figure 6 As shown, there can be multiple second circuit boards 23. Multiple second circuit boards 23 can divide the accommodation space into chambers 201. Of course, the number of second circuit boards 23 can also be one, which can be set according to actual conditions.

[0068] In some other embodiments, the circuit board assembly 20 may not include the second circuit board 23 . In this case, the electrical system may be electrically connected only through the first circuit board 21 .

[0069] In some embodiments, as Figure 6 As shown, vehicle 100 also includes a connecting pipe 30. The connecting pipe 30 is disposed within the accommodation space. Thus, the accommodation space formed by the plurality of first circuit boards 21 allows the connecting pipe 30 to be disposed within the accommodation space, achieving efficient use of the space. For example, the connecting pipe 30 may be a connecting pipe 30 for circulating washing water, oil, or cooling medium.

[0070] In some embodiments, as Figure 6 As shown, vehicle 100 also includes a connecting cable 40. Connecting cable 40 is routed through the storage space. When certain electrical connections in the electrical system cannot be connected via the circuit board, connecting cable 40 can be used. Furthermore, since connecting cable 40 can be placed within the storage space, space utilization can be optimized. Exemplarily, connecting cable 40 can be used for coaxial transmission, Ethernet transmission, high-speed data (HSD) transmission, or universal serial bus (USB) transmission.

[0071] In some embodiments, vehicle 100 further includes a filling material. The filling material is filled within the accommodation space. The filling material stabilizes the connecting cable 40 or connecting pipe 30 within the accommodation space, preventing them from swaying. For example, the filling material may be a soft material such as foam. Alternatively, the filling material may be a sealant or other material.

[0072] In some embodiments, as Figure 7As shown, the circuit board assembly 20 further includes a housing 24. A mounting space is formed within the housing 24. Multiple first circuit boards 21 are positioned within the mounting space. Thus, by providing the housing 24, the first circuit boards 21 can be positioned within the housing 24, protecting the first circuit boards 21 from direct impact from the outside.

[0073] In some embodiments, as Figure 8 As shown, the vehicle body 10 may include a beam structure 101. The circuit board assembly 20 may be disposed within the beam structure 101. Thus, the beam structure 101 as a whole can protect the circuit board assembly 20. Furthermore, the internal space of the beam structure 101 can be utilized to conveniently install the circuit board assembly 20 without occupying additional space elsewhere.

[0074] In some embodiments, as Figure 9 As shown, the housing 24 is formed with a snap-fit ​​groove 241. The beam structure 101 ( Figure 8 ) is engaged in the engaging groove 241 and connected to the housing 24. In this way, the circuit board assembly 20 can also be installed on the beam structure 101 through the engaging groove 241 formed by the housing 24, and the installation is simple, convenient and easy to implement.

[0075] In some embodiments, the vehicle 100 further includes multiple temperature sensors. These sensors are located on the multiple circuit board assemblies 20 and are used to detect the temperature of the circuit board assemblies 20. Thus, the temperature of the circuit board assemblies 20 can be monitored using these multiple temperature sensors. If the temperature of the circuit board assemblies 20 is too high, the temperature sensors can be used to promptly detect the situation, thus preventing potential safety hazards.

[0076] The present application also provides a vehicle detection method, such as Figure 10 As shown, the detection method includes steps S100-S200.

[0077] S100: Detect the temperature of multiple circuit board components. For example, Figure 11 As shown, the temperature of the circuit board assembly 20 can be detected by a temperature sensor 70. The vehicle's power management unit 50 is connected to multiple unit channels 61 of the power supply channel 60 and can control the conduction and disconnection of the power supply channel 60. The power management unit 50 is also electrically connected to the temperature sensors 70 on the multiple circuit board assemblies 20. In this way, the temperature detected by the temperature sensor 70 can be transmitted to the power management unit 50.

[0078] S200: Determine whether the temperature of the multiple circuit board assemblies is abnormal. By determining whether the temperature of the circuit board assemblies is abnormal, it is possible to determine whether the circuit board assemblies are faulty, thereby avoiding the occurrence of safety hazards. For example, refer to Figure 11If one of the circuit board assemblies 20 has a high temperature and fails, the power management unit 50 can disconnect the corresponding unit channel 61 to prevent the temperature of the circuit board assembly 20 that may fail from continuing to rise.

[0079] Wherein, when the circuit board assembly 20 includes a plurality of first circuit boards 21 ( Figure 3 ), detecting the temperatures of the plurality of circuit board assemblies 20 includes detecting the temperatures of the plurality of first circuit boards 21, where the highest temperature among the plurality of first circuit boards 21 is the temperature of the circuit board assembly 20. Thus, the temperature of the circuit board assembly 20 is the highest temperature among the plurality of first circuit boards 21, ensuring that the temperature used in subsequent determinations of whether the temperature of the circuit board assembly 20 is abnormal is the highest temperature among the first circuit boards 21 in the circuit board assembly 20, thereby ensuring safe and reliable detection results.

[0080] In some embodiments, after detecting the temperatures of the plurality of circuit board components, as shown in FIG. Figure 12 As shown, the vehicle detection method may further include step S300.

[0081] S300: Compare the temperatures of the plurality of circuit board components in pairs in sequence to obtain a plurality of groups of temperature difference values.

[0082] Determining whether the temperatures of the plurality of circuit board assemblies are abnormal includes step S201 .

[0083] S201: Compare the multiple sets of temperature differences with a preset temperature difference. If the temperature difference is greater than the preset temperature difference, the temperature of the circuit board assembly is abnormal. By comparing the temperature differences between the circuit board assemblies, if the temperature difference between the circuit board assemblies is excessively high, exceeding the preset temperature difference, it can be determined that one of the two sets of circuit board assemblies has a higher temperature, and the circuit board assembly may be faulty.

[0084] It is understandable that the detection time of the circuit board assembly can be designed according to actual conditions. For example, the temperature of one side of the circuit board assembly can be detected every 100 ms to obtain the temperature difference.

[0085] Different preset temperature differences can be set for different ambient temperatures and operating conditions. For example, a different preset temperature difference can be set for every 5°C change in ambient temperature. When the ambient temperature is 25°C, the preset temperature difference can be a first preset temperature difference. When the ambient temperature is 30°C, the preset temperature difference can be a second preset temperature difference. The first preset temperature difference and the second preset temperature difference can be different.

[0086] As an example, based on the steps of the above scheme, the complete detection process can be as follows Figure 13As shown. First, the vehicle is powered on. Then the power management unit uses the temperature sensor to detect the temperature difference every 100ms, and compares the temperature difference with the preset temperature difference. If the temperature difference is less than or equal to the preset temperature difference, the temperature difference detection is repeated. If the temperature difference is greater than the preset temperature difference, the vehicle will issue an abnormal reminder and can perform a self-check after parking. Specifically, the different unit channels of the circuit board assembly itself can be used to power on and off each unit channel of the circuit board assembly, perform temperature difference detection, and find the abnormal unit channel. Among them, if the temperature difference decreases after disconnecting a unit channel, it means that the unit channel is an abnormal unit channel, and a high temperature anomaly will occur when the channel is connected.

[0087] Of course, in other embodiments, such as Figure 14 As shown, determining whether the temperatures of the plurality of circuit board assemblies are abnormal includes step S202.

[0088] S202: Comparing the temperatures of the plurality of circuit board assemblies with a preset temperature. If the temperature of the circuit board assembly is greater than the preset temperature, the temperature of the circuit board assembly is abnormal. Thus, by directly comparing the temperature of the circuit board assembly with the preset temperature, if the temperature of the circuit board assembly is too high, greater than the preset temperature, it can be determined that the circuit board assembly has a high temperature and may be faulty.

[0089] Further, such as Figure 15 As shown, after determining that the temperature of the circuit board assembly is greater than the preset temperature, the system can further determine whether the temperature of the circuit board assembly exceeds the alarm temperature. If so, the vehicle will be immediately stopped, the power supply will be cut off, and the vehicle will be powered off. If the temperature of the circuit board assembly does not exceed the alarm temperature, the unit channel corresponding to the overheated circuit board assembly can be disconnected first. Then, it is determined whether the accumulated temperature exceeds T0 during the next cycle. If it does not exceed T0, the vehicle can continue driving. If it exceeds T0, the vehicle will need to stop and the power supply will be cut off for inspection.

[0090] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
