Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment testing technology, specifically to a desktop test bench for an intelligent cockpit. Background Technology

[0002] The main components of a smart cockpit include an in-vehicle infotainment system, a streaming rearview mirror, a head-up display (HUD), a fully digital instrument cluster, and a vehicle networking module. These components together form a complete smart cockpit system, enabling intelligent interaction between the vehicle and people, the road, and the vehicle itself. Typically, a vehicle's smart cockpit should include at least an in-vehicle infotainment system and corresponding display and input devices. Users input signals into the in-vehicle infotainment system via the input devices, and the system then controls the relevant entertainment programs. To ensure the smart cockpit operates as designed, it usually requires pre-testing and debugging.

[0003] To facilitate the testing of related equipment, existing technologies already include corresponding test benches. For example, Chinese patent CN202110421299.8 discloses a test bench system based on a vehicle intelligent cockpit, comprising a test bench, a host computer, a bus module, a power module, and a test software system. The test bench system arranges and tests the system hardware and the object under test (DUT) through the test bench, and achieves automated testing through the test software system. The host computer controls the reception and transmission of bus signals, and communicates with the DUT through the bus module to perform corresponding data acquisition and analysis. The test bench system has good wiring compatibility and scalability. Through simple matching and expansion, it can meet the requirements of different vehicle platforms and test objects, simulate the intelligent cockpit testing environment, and conduct bench tests at different stages of R&D. It can meet the relevant testing needs of intelligent cockpit equipment and software in the early stages of R&D when there is no actual prototype vehicle, and can also support extreme condition testing of mass-produced vehicles, reducing the time and labor costs of real-vehicle testing and shortening the R&D cycle.

[0004] However, in actual implementation, the inventors found that the test signals of this type of test bench are usually injected by simulation software rather than generated by real operation, which leads to the problem that the test results are not realistic enough. Utility Model Content

[0052] The test simulation button 3 is a button that is expected to be installed in the vehicle, such as an air conditioning knob, a camera switch, a joystick, etc. When triggered, it can generate a button signal corresponding to the button in the vehicle and send it to the vehicle's infotainment system to verify the function.

[0053] In one embodiment, the side of the platform housing 1 is a right trapezoid;

[0054] The hypotenuse of the right trapezoid forms the front of the frame box;

[0055] The back of the stand box is equipped with a cabinet door 12.

[0056] Specifically, to achieve better fixation, this embodiment includes a hollow platform housing 1 that is right-angled trapezoidal in side view, facilitating its placement at the testing station. Simultaneously, the inclined front surface allows the test display screen 2 to be tilted, providing testers with a more accurate viewing angle and enabling testing of component display accuracy during certain test items, such as UI testing.

[0057] The cabinet door 12 is rectangular. A rotating device is provided on one side of the back of the frame box 1 along the vertical direction. The cabinet door 12 is rotatably mounted on the frame box through the rotating device.

[0058] In the embodiment shown in the figure, a vertically arranged rotating device is installed on the right side of the cabinet body facing the back. Taking a hinge as an example, the hinge assembly includes at least two hinges, which are arranged vertically on the inner side panel of the right side near the back. The other end of the hinge assembly is connected to the back of the cabinet door 12. In other embodiments, the rotating device can also be a pivot, for example, installed inside the cabinet body 1. Cabinet door mounting holes are provided at the upper and lower ends of the right side facing the back. The corresponding position of the cabinet door 12 also has a matching pivot mounting hole. The cabinet door mounting hole matches the pivot mounting hole, and the pivot passes through the middle for fixation.

These holes are typically square holes, spaced evenly. When installing the test display 2, the corresponding display mounting hole 13 can be arbitrarily selected according to the specifications of the test display 2 and the hole positions of the display mounting bracket 21 on the back. Then, the test display 2 is installed by tightening the display mounting bracket 21 from the inside using fasteners. This allows for quick replacement of the test display 2 to meet the display specifications of different vehicle-mounted displays, realistically simulating the real vehicle environment.

[0082] In one embodiment, the test simulation button 3 includes multiple sets of corresponding signal simulation switches 31 and signal simulation knobs 32.

[0083] Specifically, to achieve better control over the input signal, in this embodiment, the test simulation button 3 is equipped with two types of switches: a signal simulation switch 31 and a signal simulation knob 32, to input different types of signals. The signal simulation knob 31 is used to input specific analog or digital input signals, such as switch amplitude, and to input specific analog or digital level signals, such as high-level or low-level signals. In another embodiment, the signal simulation switch 31 and the signal simulation knob 32 are paired signals; that is, the signal simulation switch 31 is used to select whether to connect the corresponding signal simulation knob 32.

[0084] In one embodiment, a cable management box 7 is provided in the stand housing 1.

[0085] Specifically, considering that a large number of switches, displays and power supply harnesses have a lot of wiring redundancy after being connected to the vehicle's main unit under test, a cable management box 7 is also provided in the test bench housing 1 in this embodiment. The cable management box 7 is a hollow box without a top cover, used to put in the excess cable harnesses.

[0086] In one embodiment, a power interface module 16 is provided on the left or right side of the test stand housing 1.

[0087] The power module 8 is installed inside the chassis 1;

[0088] The first end of the power module 8 is connected to the power interface module 16;

[0089] The second end of power module 8 is connected to the vehicle's infotainment system under test.

[0090] Specifically, to power the vehicle's control unit under test, this solution also includes a power module 8. The input of power module 8 connects to a power interface module 16, which is a bidirectional slot fixed to the side panel of the housing with bolts. The outer side connects to the AC power supply line, and the inner side connects to the power supply line of the power module via a cable. The second end of power module 8 is then connected to the vehicle's control unit under test and the test display screen 2 via a power supply line. Furthermore, the power interface module 16 is a combined module; the upper part of this combined module is a 220V power input switch, and the lower part is a power harness interface.

[0091] The test bench housing 1 is also provided with an ignition signal switch button 17 on the side corresponding to the power interface module 16. The ignition signal switch button 17 is connected to the vehicle unit under test via a switch cable.

[0092] The ignition signal switch button 17 is used to simulate the ACC start signal when the actual vehicle is powered on. By triggering the ignition signal switch button 17, the corresponding ACC start signal is input to the vehicle's infotainment system under test, so that the vehicle's infotainment system under test is powered on and the process of starting up the vehicle's infotainment system is simulated.

[0093] In addition, an ammeter display screen 18 is provided below the ignition signal switch button 17. The ammeter display screen 18 is connected to the ammeter output terminal in the power module 8 and is used to display the real-time output current of the power module 8.
