Description

Technical Field

[0001] This utility model relates to a testing device, specifically a testing device for new energy vehicles based on the OBD interface. Background Technology

[0002] With the development of the new energy vehicle industry, the off-line testing of new energy vehicles is becoming increasingly standardized. There are off-line testing based on OTA technology and off-line testing based on OBD interface. Among them, the OBD interface-based off-line testing has become the mainstream of new energy vehicle off-line testing due to its advantages of low technical threshold, high maturity and wide applicability. However, compared with the off-line testing based on OTA technology, the OBD interface-based off-line testing relies on UDS physical addressing for off-line calibration, flashing, fault diagnosis and testing. Furthermore, due to the different physical addresses of different vehicle control units and the different UDS custom contents, there are many types of off-line testing equipment, different adapters, and the inability to trace off-line data. The OBD interface-based off-line testing equipment for new energy vehicles designed in this solution perfectly solves these three problems. Utility Model Content

[0003] The purpose of this utility model is to integrate a whole vehicle EOL off-line testing system, combine new energy vehicle off-line testing equipment, and use "intelligent and digital" methods to make new energy vehicle data controllable, thereby improving the efficiency of off-line testing of new energy vehicle powertrain and whole vehicle controller.

[0004] This utility model is achieved through the following technical solution:

[0005] A new energy vehicle off-line testing device based on an OBD interface includes a cabinet, audible and visual alarm indicators, a monitor, a keyboard and mouse, an industrial computer, an adapter, a UPS power supply, a barcode scanner, a printer, and related wiring harnesses.

[0006] The cabinet is equipped with audible and visual alarm indicator lights on the top exterior. The interior is divided into three layers: the upper layer houses the monitor, with a printer placed behind it; the upper cabinet door is a transparent glass window. The middle layer has pull-out trays for the keyboard, mouse, and barcode scanner. The lower layer is divided into two sections separated by a partition; the lower section houses the UPS power supply, and the lower section houses the industrial control computer.

[0007] The UPS power supply is connected to the mains power via a three-prong power cord; the monitor, industrial computer, and printer are connected to the UPS power supply via power cords; the monitor is connected to the industrial computer via VGA, DP, or HDMI video cables; the barcode scanner, keyboard and mouse, printer, and audible and visual alarm indicator lights are connected to the industrial computer via USB data cables; the adapter is connected to the industrial computer via USB, Bluetooth, or WIFI, and is also connected to the new energy commercial vehicle via an OBD extension cable; the industrial computer is connected to an internet switch or internet port via a gigabit network cable.

[0008] The industrial control computer has data processing capabilities. It can identify the operator's intentions, manage and allocate resources, and control each device to perform specific tasks via USB data cable, VGA / HDMI video cable, and power cable. At the same time, it can send the data information written to the vehicle to the network platform via wired or wireless network to collect vehicle status statistics, verify vehicle parameters, and trace vehicle data.

[0009] The adapter serves as the sole channel for interaction between the device and the vehicle. It transmits the data information output by the offline testing device to the main chipset via the USB interface. Within the main chipset, the data is amplified by an operational amplifier and then transmitted to the main chip. The main chip analyzes the signal according to the current USB 3.0 protocol, converts the signal into high and low levels via a CAN transceiver, and transmits it to the vehicle's CAN network via an automatic jumper and OBD interface to control the various control units of the vehicle to perform relevant tasks.

[0010] The audible and visual alarm indicator light has three different colors: red, green, and yellow, as well as a buzzer alarm. Red indicates an error in the offline detection, green indicates a successful offline detection, and yellow indicates that the offline detection is in progress. When the detection fails, the red light illuminates and an 80dB buzzer sounds to remind the operator that the offline detection has failed and to handle it promptly.

[0011] The barcode scanner automatically transmits the scanned information to the industrial control computer by scanning the unique barcode of the new energy commercial vehicle.

[0012] The printer prints out the vehicle off-line inspection results and adds them to the assembly result list on the production line for use by subsequent workstations.

[0013] The testing equipment is also equipped with a leakage current protector and is placed together with the UPS power supply.

[0014] This invention can improve the efficiency of new energy vehicle off-line testing, trace the data of the electronic control unit of new energy vehicles, establish a single vehicle file for new energy vehicles, reduce the communication costs of after-sales service, and build the market competitiveness of vehicle brands.

[0019] like Figure 1-3 As shown, this utility model is a new energy vehicle off-line testing device based on the OBD interface, including a cabinet, an audible and visual alarm indicator light 1, a display 2, a keyboard and mouse 3, an industrial control computer 4, an adapter 5, a UPS power supply 6, a barcode scanner 7, a printer 9, and related wiring harnesses.

[0020] The functions of each component are as follows:

[0021] Server rack: Serving as the main supporting structure for the equipment, the rack features an audible and visual alarm indicator light on its upper exterior and a barcode scanner on its right-center side. The interior is divided into three layers: upper, middle, and lower. The upper layer houses the monitor, with a printer behind it. The upper rack door is a transparent glass window for easy operation. The middle layer has a pull-out tray for the keyboard, mouse, and barcode scanner. The lower layer is divided into two sections separated by a partition. The lower section houses the UPS power supply and leakage protection device, while the lower second section houses the industrial control computer.

[0022] Display: As a window for interaction between the device and the user, the visual characteristics can quickly inform the operator of the current status of the device.

[0023] Industrial PC: As the brain of the entire equipment, it has data processing capabilities. Through USB data cable, VGA / HDMI video cable, and power cable, it recognizes the operator's intentions, manages and allocates resources, and controls each device to perform specific tasks, reflecting the "intelligent" characteristics of the equipment. At the same time, the industrial PC also has the characteristics of "digitalization". It sends the data information written to the vehicle to the network platform through wired or wireless network, and counts the vehicle status, verifies the vehicle parameters, and traces the vehicle data.

[0024] Barcode scanner: The purpose of a barcode scanner is to improve the convenience of the operator. By scanning the unique barcode (VIN code) of a new energy commercial vehicle, the scanned information is automatically transmitted to the industrial control computer, reducing the amount of manual operation and improving the level of intelligence.

[0025] UPS power supply: As the energy center of the equipment, it supplies power to all components of the equipment. At the same time, considering the problem of power supply interruption in the operating environment, the UPS power supply also has the characteristic of storing electrical energy. After the power is cut off, it keeps the equipment running and uploads the current data to the network platform.

[0026] Keyboard and mouse: As the starting point of human-computer interaction, they input the operator's actions to the central processing unit.

[0027] The adapter serves as the sole channel for interaction between the equipment and the vehicle. It transmits data from the off-line testing equipment to the main chipset via a USB interface. Within the main chipset, the data is amplified by an operational amplifier and then fed into the main chip. The main chip, following the current USB 3.0 protocol, parses the signal and converts it to high and low levels via a CAN transceiver. This signal is then transmitted to the vehicle's CAN network via an automatic jumper and the OBD interface, controlling various vehicle control units to perform relevant tasks. It acts as a "communication bridge" between the off-line testing equipment and the vehicle.

[0028] Audible and visual alarm indicator: As the endpoint of human-machine interaction, it features three different colors—red, green, and yellow—along with a buzzer alarm. Red indicates an error in the offline detection, green indicates a successful offline detection, and yellow indicates that the offline detection is in progress. When a detection failure is indicated, the red light illuminates and an 80dB buzzer sounds, alerting the operator to the offline detection malfunction and prompting timely handling.

[0029] Printer: Print out the vehicle off-line inspection results and add them to the assembly result list on the production line for use by subsequent workstations.

[0030] Residual current device (RCD): It has an emergency safety protection mechanism that can cut off the power supply in time when a short circuit fault occurs in the internal wiring of the equipment, protecting the components from being affected and increasing the safety and reliability of the equipment.

[0031] Related wiring harnesses: These are mainly responsible for connecting the various components into a whole. The wiring harness connection is shown in the diagram below. The UPS power supply is connected to the mains power through a three-prong power cord; the monitor, industrial computer, and printer are connected to the UPS power supply through power cords; the monitor is connected to the industrial computer through a VGA, DP, or HDMI video cable; the barcode scanner, keyboard and mouse, printer, and audible and visual alarm indicator lights are connected to the industrial computer through USB data cables; the adapter is connected to the industrial computer through USB, Bluetooth, or WIFI, and is also connected to the new energy commercial vehicle through an OBD extension cable; the industrial computer is connected to an internet switch or internet port through a gigabit network cable.

[0032] The advantages of this invention are: it features a wired network connection, enabling digital management and tracing of vehicle off-line data; it uses an industrial control computer instead of handheld devices, relying on powerful computing capabilities to accelerate data processing and improve vehicle off-line inspection efficiency; and it is compatible with multiple diagnostic protocols, reducing the number of off-line devices and lowering usage and learning costs.
