Description

Technical Field

[0001] This utility model relates to the field of controller testing technology, specifically a vehicle controller testing platform. Background Technology

[0002] The vehicle controller is a core component of modern automotive electronic systems, primarily responsible for functions such as energy management, powertrain coordination and control, and fault diagnosis. Before being put into use, the vehicle controller needs to be tested, which involves conducting various tests on its hardware, software, and functions using a testing platform.

[0003] Existing vehicle controller testing platforms are mostly large desktop cabinets or fixed racks, which have the following problems when used: they are large in size and require the connection of multiple instruments, such as power supplies, CAN cards, load boxes, etc., and are difficult to move at the same time. When testing the controller, it is necessary to connect it while maintaining its positioning stability. However, the existing side-view platforms have cumbersome positioning mechanisms that are not conducive to quick installation and disassembly.

[0004] In view of the above-mentioned problems, this technical solution designs a vehicle controller test platform. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vehicle controller test platform includes a test box. The test box comprises, from top to bottom, a stepped test platform, an integrated signal processing compartment, and a battery compartment. The stepped test platform is located on the outside of the test box. The integrated signal processing compartment and the battery compartment are respectively located on the upper and lower sides of the test box's interior. The stepped test platform, integrated signal processing compartment, and battery compartment are connected via wire holes to ensure the coordinated operation of each platform, compartment's internal structure, and components. A removable lithium battery pack is installed inside the battery compartment, supporting long-term battery life. An integrated signal processing board is installed inside the integrated signal processing compartment, replacing multiple external... The design aims to reduce space occupancy. A touchscreen is embedded on one side of the top of the stepped test bench, and a controller positioning platform is located on one side of the lower part of the stepped test bench. A test interface panel is located on the vertical side wall connecting the top and bottom of the stepped test bench. The test interface panel is electrically connected to the touchscreen, integrated signal processing board, and detachable lithium battery pack through cables, thus forming a complete test closed-loop system. The vehicle controller to be tested is placed on the controller positioning platform for adaptive and rapid positioning. Then, it is connected to the touchscreen and integrated signal processing board through the test interface panel. Finally, the corresponding tests are performed by operating the touchscreen.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] By integrating a signal processing board to replace multiple peripherals such as power supply, CAN card, and load cell, the device size is significantly reduced, portability is improved, and integrated design is achieved.

[0010] The clamping plate is guided to move by a T-shaped slide rail and a slider. Combined with screw adjustment and rotating connecting block, the vehicle controller can be adaptively clamped. The operation is simple and the stability is high, enabling rapid positioning. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-3A vehicle controller test platform includes a test box 10. The test box 10 has, from top to bottom, a stepped test platform 11, an integrated signal processing compartment 12, and a battery compartment 13. The stepped test platform 11 is located on the top exterior of the test box 10. The integrated signal processing compartment 12 and the battery compartment 13 are respectively located on the upper and lower sides inside the test box 10. The stepped test platform 11, the integrated signal processing compartment 12, and the battery compartment 13 are connected through wire holes, ensuring the connection and coordinated operation of each platform, compartment's internal structure, and components. A removable lithium battery pack 19 is installed inside the battery compartment 13, supporting long-term battery life. An integrated signal processing board 20 is installed inside the integrated signal processing compartment 12, which is used to replace... Multiple peripheral devices reduce space occupation. At the same time, a touch screen 21 is embedded on one side of the top of the stepped test bench 11, and a controller positioning platform 22 is set on one side of the lower part of the stepped test bench 11. A test interface panel 24 is set on the vertical side wall connecting the top and bottom of the stepped test bench 11. The test interface panel 24 is electrically connected to the touch screen 21, the integrated signal processing board 20 and the detachable lithium battery pack 19 through cables to form a complete test closed-loop system. That is, the vehicle controller 23 under test is placed on the controller positioning platform 22 for adaptive and rapid positioning, and then connected to the touch screen 21 and the integrated signal processing board 20 through the test interface panel 24. Then, the corresponding tests are performed by operating the touch screen 21.

[0023] In this embodiment of the invention, two sets of battery compartment doors 14 are symmetrically hinged on one side of the battery compartment 13 for opening and closing the battery compartment 13, which provides convenience for the entry and exit of the detachable lithium battery pack 19. At the same time, a push-pull compartment plate 15 is provided on one side of the integrated signal processing compartment 12. By manually operating the push-pull compartment plate 15 to move laterally, the opening and closing of the integrated signal processing compartment 12 can be controlled.

[0024] Specifically, the integrated signal processing compartment 12 corresponding to the push-pull compartment 15 has a rectangular inlet and outlet on its side wall. The rectangular inlet and outlet have symmetrically arranged grooves 18 on their upper and lower sides. One end of each groove 18 is open. A slide bar 16 is installed on the inner side of the push-pull compartment 15 corresponding to the position of the groove 18. The slide bar 16 moves laterally along the inside of the groove 18, thereby controlling the opening and closing of the rectangular inlet and outlet by the push-pull compartment 15. (See reference...) Figure 4 Meanwhile, a locking pin 17 is installed on the side of the push-pull compartment plate 15 facing the inside of the slide groove 18. The locking pin 17 has a locking hole on the inner wall of the slide groove 18. The locking pin 17 and the locking hole are used to achieve the positioning and installation between the slide bar 16 and the slide groove 18.

[0025] Meanwhile, the vertical cross-sections of the slider 16 and the slide groove 18 are set as T-shaped structures to prevent the slider 16 from detaching directly along the vertical direction of the slide groove 18;

[0026] Anti-slip blocks are installed at the four corners of the bottom of the test chamber 10 to increase the stability of the test chamber 10 when it is placed and used.

[0027] In one embodiment of the present invention, a manual positioning component is provided on the controller positioning platform 22 for clamping and positioning vehicle controllers 23 of different sizes placed on the controller positioning platform 22.

[0028] See Figure 2 , Figure 5 The manual positioning assembly includes a clamping plate 31 that moves relative to the test interface panel 24. One side of the clamping plate 31 contacts the vehicle controller 23. T-shaped sliders 30 are symmetrically mounted at both ends of the clamping plate 31. A connecting rod is rotatably connected to the middle of the clamping plate 31 away from the test interface panel 24 via a rotating connecting block 34. An adjusting screw 33 is connected to the end of the connecting rod. One side of the adjusting screw 33 is threaded through a threaded hole plate 32 fixed on the controller positioning table 22. A handle 35 is mounted on the other end of the adjusting screw 33 via the connecting rod. A set of fixed mesh baffles 36 is provided on the controller positioning platform 22 located on one side of the test interface panel 24. The fixed mesh baffles 36 are spaced apart from the test interface panel 24, and the fixed mesh baffles 36 are in contact with one side of the vehicle controller 23. That is, by manually rotating the handle 35, the adjusting screw 33 is controlled to move along the inside of the threaded hole plate 32. Then, under the connection of the rotating connecting block 34, the clamping plate 31 is driven to move toward the test interface panel 24 to fix the vehicle controller 23 placed between the clamping plate 31 and the fixed mesh baffles 36.

[0029] Meanwhile, the mesh diameter of the fixed mesh baffle 36 is much larger than the size of the connecting cables and terminals between the vehicle controller 23 and the test interface panel 24, which ensures that the vehicle controller 23 and the test interface panel 24 can be connected smoothly.

[0030] The rotating connecting block 34 is configured with a stepped structure. The clamping plate 31 has a stepped rotating hole at the position corresponding to the rotating connecting block 34. That is, the rotating connecting block 34 is rotatably connected to the stepped rotating hole, thereby maintaining the rotation between the two to prevent them from falling off.

[0031] As a preferred embodiment of the present invention, see [reference]. Figure 6 The test interface panel 24 is equipped with dual CAN-FD channels 25, analog transmission terminals 26, digital I / O interfaces 27, and a vehicle controller power interface 28. Connecting to the vehicle controller 23 via these interfaces enables the test connection. Simultaneously, a miniature electronic load array, such as a programmable resistor / capacitor array, is integrated on the integrated signal processing board 20 to replace the traditional external load box, supporting:

[0032] Sensor signal simulation: throttle, temperature, etc.;

[0033] Actuator load simulation: injectors, fans, etc.

[0034] As a preferred embodiment of the present invention, participating Figure 5 T-shaped sliders 30 are symmetrically installed at both ends of the clamping plate 31. A T-shaped slide rail 29 is provided on the controller positioning platform 22 corresponding to the bottom of the T-shaped slider 30. The T-shaped slider 30 slides along the inside of the T-shaped slide rail 29. That is, when the clamping plate 31 moves, the smoothness of the movement of the clamping plate 31 is improved by the sliding between the T-shaped slider 30 and the T-shaped slide rail 29.

[0035] In a preferred embodiment of the present invention, an insulating buffer pad is provided on the side of the clamping plate 31 and the fixed mesh baffle 36 that contacts the vehicle controller 23, in order to reduce the clamping wear on the vehicle controller 23 and prevent risks such as leakage.

[0036] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control.

[0037] Power supply start-up: Open the battery compartment door 14 and insert the removable lithium battery pack 19 to power the integrated signal processing board 20 and the touch screen 21.

[0038] Equipment connection: Place the vehicle controller 23 under test on the controller positioning platform 22, rotate the handle 35 to drive the adjusting screw 33, and push the clamping plate 31 along the T-shaped slide rail 30 to the fixed mesh baffle 36 through the rotating connecting block 34 to clamp the vehicle controller 23.

[0039] Interface docking: Pass the vehicle controller cable through the mesh hole 36 of the fixed mesh baffle and connect it to the corresponding interface 24 of the test interface panel (dual CAN-FD channel 25, analog transmission terminal 26, etc.).

[0040] Signal processing: The integrated signal processing board simulates sensor signals (such as throttle body and temperature) and actuator loads (such as fuel injectors and fans), replacing the traditional load box with a miniature electronic load array;

[0041] Test execution: Test commands are sent via touch screen 21, and the data is parsed by integrated signal processing board 20 and transmitted to the controller, and the test results are fed back in real time;

[0042] Maintenance operation: The horizontal push-pull compartment plate 15 moves within the slide groove 18 via the slide bar 16 to open the integrated signal processing compartment 12 for maintenance; the locking pin 17 is inserted into the slide groove locking hole to fix the position of the compartment plate.

[0043] It should be understood that all components in this application are made of metal or plastic materials with adaptable strength in the relevant field to ensure that their structural rigidity meets actual requirements.

[0044] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
