[0002] An electronic control unit (ECU) is one of the core components of a vehicle and is responsible for controlling various functions of the vehicle, such as the engine, transmission, chassis, battery, etc. The flashing device for the ECU is a device used to reprogram the automotive electronic control unit. After being flashed by this flashing device, the ECU can change the performance and functions of the vehicle. With the popularization of new energy electric vehicles and the increase of in-vehicle technology configurations, the functions of modern vehicle ECUs are becoming increasingly complex, the flashing files are getting larger, and the software flashing times for different ECUs are also different. During the canning process of the domain controller ECU assembly, because the flashing process takes a long time, the traditional on-line flashing method cannot be used for flashing. To facilitate parallel execution with other processes to shorten the overall vehicle software flashing time and improve the flashing efficiency, the current related technologies generally adopt the off-line flashing method.

[0003] The current off-line flashing device requires the operator to first plug the device communication connector into the ECU to ensure the subsequent flashing tasks of the device. However, this device communication connector can only achieve off-line software canning for a single type of ECU, and has poor versatility. Summary of the Utility Model

[0035] An embodiment of the present invention provides an off-line programming docking tooling 100 for realizing the docking between an industrial computer and an electronic control unit. The industrial computer can be an industrial computer.

[0036] Please refer to Figure 1 , an embodiment of the present invention provides an off-line programming docking tooling 100 for realizing the docking between an industrial computer and an electronic control unit. The industrial computer can be an industrial computer.

[0037] The off-line programming docking tooling 100 includes a support frame 10 and a programming drawer 20.

[0038] Please combine with Figure 2 , the support frame 10 includes a frame body and at least one docking mechanism 11. The docking mechanism 11 includes a connecting plate 111 detachably connected to the frame body and at least one first docking structure 112 disposed on the connecting plate 111. The first docking structure 112 can be electrically connected to the industrial computer. Among them, the first docking structure 112 can be a socket that is in plug-in cooperation with the electronic control unit, and a spring probe is provided on the first docking structure 112, and the spring probe is electrically connected to the industrial computer.

[0039] The programming drawer 20 includes a drawer body 21, a positioning mechanism 22 and a second docking structure 23.

The positioning mechanism 22 includes a positioning plate 221 detachably connected to the drawer body 21 and a positioning structure 222 disposed on the positioning plate 221. The second docking structure 23 can be electrically connected to the industrial computer. The second docking structure 23 is slidably connected to the drawer body 21 and can be plugged into a connector by sliding relative to the drawer body 21. The positioning structure 222 is used to position the housing on the electronic control unit so that the first docking structure 112 can be plugged into a connector when the drawer body 21 slides to the docking position. Among them, when the positioning structure 222 positions the electronic control unit, the electronic control unit can abut against the positioning plate 221 or be spaced apart from the positioning plate 221.

[0040] It should be noted that the first plugging structure 112 can be plugged into the plug-in component at the rear side of the electronic control unit, and the second plugging structure 23 can be plugged into the plug-in components on other sides of the electronic control unit except the rear side. That is to say, the first plugging structure 112 can be applicable to an electronic control unit with plug-in components on only one side. When installing this electronic control unit, the side with the plug-in component can be oriented backward. The first plugging structure 112 and the second plugging structure 23 can be jointly applicable to an electronic control unit with plug-in components on both sides. When installing this electronic control unit, one of the sides with the plug-in components can be oriented backward. The second plugging structure 23 can be arranged on one of the front side, left side or right side of the drawer body 21. When there are plug-in components on three or more sides of the electronic control unit, multiple second plugging structures 23 can also be provided, and each second plugging structure 23 is respectively arranged corresponding to one plug-in component on one side.

[0041] For the convenience of description, it is described with plug-in components provided on both the front side and the rear side of the electronic control unit.

[0042] During use, the drawer body 21 can be first pulled out to the pulled-out position, then the electronic control unit is positioned through the positioning structure 222, and then the second plugging structure 23 is slid so that the second plugging structure 23 is plugged into the plug-in component on the front side of the electronic control unit. Then the drawer body 21 is pushed to the plugging position so that the plug-in component on the rear side of the electronic control unit is plugged into the first plugging structure 112. Of course, if there are only plug-in components on the rear side of the electronic control unit, there is no need to operate the second plugging structure 23, and only the drawer body 21 needs to be pushed to the plugging position so that the plug-in component on the rear side of the electronic control unit is plugged into the first plugging structure 112.

[0043] This off-line programming docking tooling can replace manual operation to realize the plugging and unplugging of the electronic control unit, reduce the damage rate of the electronic control unit, lower the working intensity, and perfectly solve the related problems of repeatedly plugging and unplugging multiple plugs during production programming. Since the positioning mechanism 22 is detachably connected to the drawer body 21, and the plugging mechanism 11 is detachably connected to the frame body, therefore, for different models of electronic control units, a suitable positioning mechanism 22 can be selected and installed on the drawer body 21, and a suitable plugging mechanism 11 can be selected and connected to the frame body so that different models of electronic control units can all realize electrical connection with the industrial control computer through this off-line programming docking tooling. In this way, by replacing two components, different electronic control units can be compatible for programming, reducing the production cost, improving the production efficiency, and having strong versatility.

The control device 91 is also electrically connected to the industrial control computer. The control device 91 is used to send instructions to the industrial control computer so that the industrial control computer flashes the electronic control unit.

[0067] Optionally, the flashing device further includes an operation table 93. The operation table 93 has a tabletop, and the control device 91 is provided on the tabletop. The display 92 can be set on the top of the rack body or on the tabletop. The control device 91 includes a keyboard 911 and a mouse 912 both electrically connected to the industrial control computer. The mouse 912 and the keyboard 911 can both be placed on the tabletop for easy operation by the operator. The display interface of the display 92 is used to display control options, information of the target electronic control unit to be flashed, and the control process screen. The operator operates the keyboard 911 and the mouse 912 by viewing the display interface of the display 92 to input instructions to the industrial control computer.

[0068] Among them, the operation table 93 can be fixedly connected to the rack body for easy assembly and handling. Each flashing drawer 20 is located above the operation table 93 for easy operation of the flashing drawer 20 by the operator.

[0069] Optionally, the control device 91 may further include a printer 94, a relay, a burner, a power supply, and a power control switch all electrically connected to the industrial control computer.

The printer 94 can be a label printer 94 to print the information of the flashed electronic control unit after the flashing is completed.

[0070] Optionally, the flashing device further includes a refrigeration device. The refrigeration device is connected to the rack body and is used to dissipate heat from the offline flashing plug-in tool 100. Among them, the refrigeration device can be an air conditioner.

[0071] When the flashing device is in use, first, an employee clicks the start flashing option on the display interface of the monitor 92 with the mouse 912, so that the relay sends a "start flashing" instruction to the host computer. After receiving the instruction, the host computer reads the vehicle data information through the running program and displays the information of the target electronic control unit to be flashed on the display interface of the monitor 92. After the operator checks it, the operator takes the target electronic control unit.

[0072] Place the target electronic control unit in the designated flashing drawer 20 according to the information prompt. After the first groove on the outer shell of the target electronic control unit is well matched with the guiding block 2222, the positioning post 2221 can be inserted into the second groove or the connecting hole to realize the positioning of the outer shell of the information of the electronic control unit.

[0073] Then the operator manually closes the flashing drawer 20, and the flashing drawer 20 drives the target electronic control unit to move parallel towards the plugging mechanism 11 until the drawer body 21 moves to the plugging position. The plug-in on the target electronic control unit is inserted into the first plugging structure 112 under the push of the flashing drawer 20. The spring probe on the first plugging structure 112 is connected to the burner through a wire harness, thus forming a complete signal link.

[0074] The host computer sends an instruction to the target electronic control unit through the communication card to detect connectivity. If the target electronic control unit has a reply, the host computer will receive a connectivity signal, indicating that it is connected. If no reply is received, it means it is not connected. If it is not connected, the host computer will enter the error handling process. The error handling process is as follows: The program controls the relay not to close through the instruction, the indicator light 27 does not light up, and an error message prompt is displayed at the corresponding position on the display interface of the display screen. If it is connected, the cooling fan starts to run, and at the same time the indicator light 27 lights up and shows green, indicating that the flashing is in progress. The program automatically executes the flashing to perform software canning on the target electronic control unit.

[0075] Finally, judge the flashing status by observing the status indicator light 27. After the flashing is completed, the program controls the relay to cut off the power through the instruction. The extinguishing of the status indicator light 27 indicates that the flashing has been completed. The host computer will record the flashing result in the database and wait for the operator to take out the target electronic control unit;

[0076] If the operator sees that the status indicator light of the flashing table is extinguished, the operator can step forward to check the specific flashing result for the next step of processing. If the displayed result is normal, the operator opens the drawer to take out the target electronic control unit. After the flashing is successful, the label printer 94 automatically prints a label, and the operator pastes the label on the designated area on the outer surface of the target electronic control unit, that is, the flashing work is completed.
