[0023] The embodiments of the present utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be understood that the preferred embodiments are only for explaining the present utility model, rather than for limiting the protection scope of the present utility model.

[0024] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in its actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0025] In the following description, a large number of details are explored to provide a more thorough explanation of the embodiments of the present utility model. However, it is obvious to those skilled in the art that the embodiments of the present utility model can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present utility model difficult to understand.

[0026] A CCD measuring instrument is a measuring instrument that uses a CCD (Charge-Coupled Device) as an image sensor. It can convert the image of the object surface into a digital signal, thereby realizing the measurement and analysis of parameters such as the size, shape, and position of the object.

[0027] New energy vehicles have become one of the important means of transportation. The power source of pure electric vehicles is the power battery. As a component that bears the force of the power battery, the force-bearing strength and the quality during operation of the battery box are very important. Currently, there are multiple welds on the battery box. In the related art, the welds of the battery box are mainly subjected to airtightness detection during production. During the process of users using the vehicle, generally only the operation data of the power battery is monitored, and the welds of the power battery box are not monitored. There is a situation where the operation parameters of the power battery are normal, but the welds of the battery box crack due to external forces. If there are cracks in the welds of the power battery box, the airtightness of the battery box is abnormal. If the problem of the battery box is not dealt with for a long time and the user continues to use the vehicle, it will accelerate the aging of the power battery and there is a risk of battery water ingress. Moreover, the internal parameters of the power battery will change, and even there is a risk of vehicle failure and vehicle fire caused by the power battery.

[0028] To solve the above problems, asFigure 1 As shown in the figure, the present application provides a system including a visual detection device 110 for detecting the weld of a battery box and generating a detection signal, a vehicle controller 120 for responding to the detection signal to generate a prompt message, and a display device 130 for displaying the prompt message. The visual detection device 110 is disposed at the weld of the battery box. The visual detection device 110 is connected to the vehicle controller 120, and the vehicle controller 120 is connected to the display device 130.

[0029] During the driving of the vehicle, there may be abnormal signal transmission between the visual detection device 110 and the vehicle controller 120 due to reasons such as road conditions. Therefore, the battery management system can also be used to transmit the detection signal output by the visual detection device 110.

[0030] Specifically, as Figure 2 shown in the figure, the system further includes a battery management system 140 for collecting the detection signal. The visual detection device 110 is connected to the battery management system 140, and the battery management system 140 is connected to the vehicle controller 120.

[0031] More specifically, the visual detection device 110 includes a camera unit and an image processing unit. The camera unit is disposed facing the weld of the battery box. The camera unit is connected to the image processing unit, and the image processing unit is connected to the vehicle controller. Specifically, the visual detection device takes a photo of the weld of the battery box, processes the taken image, and determines whether there is a crack in the weld of the battery box according to the image. The visual detection device can use a CCD measuring instrument. The CCD camera in the CCD measuring instrument is the camera unit, and the camera unit is used to take a photo of the weld of the battery box. The central processor in the CCD measuring instrument can be the image processing unit, and the image processing unit is used to process the photo taken by the camera unit, generate a detection signal according to the result of the image processing, and transmit the generated detection signal to the vehicle controller 120.

[0032] More specifically, the visual detection device 110 further includes an illumination unit, and the illumination unit is disposed outside the weld of the battery box. Specifically, the light source in the CCD measuring instrument is the illumination unit, and the photo unit is used to illuminate the weld to be photographed.

[0033] More specifically, the visual detection device 110 further includes a timing unit, and the timing unit is connected to the camera unit. The timer in the CCD measuring instrument can be the timing unit, and the timing unit is used to wake up the camera unit to take a photo at intervals.

[0034] To detect all the welds of the battery box, it is necessary to set up a visual detection device 110 on each weld of the battery box. Multiple visual detection devices 110 are required to achieve full coverage of the welds on the battery box. To reduce the cost of weld detection and the number of visual detection devices 110, the system also includes a guide rail for installing the visual detection device 110, and the visual detection device 110 moves on the guide rail. When performing weld detection, the corresponding guide rail can be set according to the welds of the battery box, and the visual detection device 110 is set on the guide rail, so that the visual detection device 110 can move on the guide rail, thereby reducing the number of visual detection devices 110 and the cost of detecting the welds of the battery box.

[0035] More specifically, the guide rail includes a single guide rail, parallel guide rails, and combined guide rails. The parallel guide rails include at least two parallel guide rails. The combined guide rail includes a single guide rail and a parallel rail group partially arranged on the single guide rail. The parallel rail group includes multiple guide rails parallel to the single guide rail. As Figure 3 shown, the guide rail can be a single guide rail. The visual detection device 110 is set on the single guide rail, and the visual detection device 110 moves on the single guide rail to detect the welds of the battery box. However, the detection time of the single guide rail is relatively long and the efficiency is relatively low. Parallel guide rails can also be used. As Figure 3 shown, the parallel guide rails are at least two parallel guide rails. The visual detection device 110 is set on each single guide rail. When the visual detection device 110 detects the battery welds, the detection time can be shortened. Since the lengths of the welds of the battery box vary, combined guide rails can also be used. As Figure 3 shown, the combined guide rail includes an integral single guide rail. At the place where the weld of the battery box is relatively long, in order to shorten the detection time of the weld, a parallel rail group is set at the corresponding weld. The parallel rail group is composed of multiple guide rails parallel to the single guide rail. Multiple visual detection devices 110 can be set on the single guide rail of the combined guide rail. When the detection ranges of the multiple visual detection devices 110 are less than the length of the weld of the battery box, the multiple visual detection devices 110 are respectively set on the corresponding guide rails to complete the detection of the weld in the shortest time.

[0036] More specifically, multiple docking points are set on the guide rail, and the visual detection device detects the welds of the battery box when it docks at any one of the docking points. Specifically, the docking points of the guide rail can be determined according to the shooting range of the visual detection device 110 and the welds of the battery box, so that the visual detection device 110 takes pictures of the welds at each docking point, and the pictures taken at the multiple docking points are combined to obtain a photographed image of the entire weld of the battery box.

[0037] More specifically, the vehicle controller 120 is connected to the vision detection device 110 and the battery management system 140 through the acquisition unit. Specifically, the vehicle controller 120 acquires detection signals through the acquisition unit, and the acquisition unit can be an analog-to-digital acquisition unit for acquiring detection signals.

[0038] As Figures 1 to 2 shown, the working principle of the vehicle battery box weld management system provided by this application is as follows:

[0039] After the vehicle leaves the factory, the vision detection device is set on the guide rail. Before the vision detection device performs detection, it is in an initial state. It can start the vision detection device 110 to detect the welds of the battery box according to the degree of influence of external forces on the vehicle, the driving road conditions of the vehicle, and the wake-up command sent by the user. It can also start the vision detection device 110 to detect the welds of the battery box at fixed intervals through the timing unit.

[0040] Detecting the welds of the battery box includes: turning on the lighting unit and the camera unit, so that the vision detection device 110 takes pictures of the welds of the battery box at multiple stopping points. After the vision detection device 110 completes the shooting at multiple stopping points, the image processing unit processes the images collected by taking pictures, identifies the positions where the welds have cracks, generates a detection signal of battery box abnormality based on the crack information, and directly sends the detection signal to the vehicle controller 120 or sends it to the vehicle controller 120 through the battery management system 140. After the vehicle controller 120 acquires the abnormal detection signal through the acquisition unit, it generates a corresponding prompt signal based on the detection signal and sends the prompt signal to the display device 130 to prompt the user that the battery box is abnormal in the shortest time.

[0041] When the vehicle is in a car wash, thunderstorm weather, or flooded state, if the welds of the battery box are abnormal, the vehicle controller 120 should prompt the user that the vehicle is prohibited from being used, and quickly cut off the power supply of the power battery through the battery management system 140 to avoid battery short-circuit caused by water entering the battery box, and ultimately cause the vehicle to catch fire and burn.

[0042] It should be noted that the vision detection device 110 detects the welds of the battery box according to its own structure, and the vehicle controller 120 generates a prompt signal based on its own structure.

[0043] This application also provides a vehicle device, including the vehicle battery box weld management system described above, which is convenient for testing the output current of the battery management system.

[0044] The present application provides a vehicle battery box weld management system and a vehicle device. The system includes a visual detection device for detecting the welds of the battery box and generating detection signals, a vehicle controller for responding to the detection signals to generate prompt information, a display device for displaying the prompt information, a battery management system for transmitting the detection signals, and a guide rail for installing the visual detection device. The visual detection device is arranged according to the welds of the battery box, and the visual detection device is connected to the vehicle controller directly or through the battery management system, and the vehicle controller is connected to the display device. By installing the visual detection device on the guide rail to detect the welds of the battery box, the present application reduces the detection cost, and determines whether cracks occur in the battery box through the visual detection device. The detected detection signals can be directly sent to the vehicle controller or sent to the vehicle controller through the battery management system. When the battery box is abnormal, the vehicle controller converts the detection signals, and sends the converted prompt information to the display device, timely discovers the sealing risk of the battery box, prompts the user to perform maintenance or replacement, effectively avoids continuing to drive for a long time after the weld cracks, causes water ingress into the battery box resulting in battery short circuit, and finally causes a fire, further improving driving safety.

[0045] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
