[0030] Please see Figures 1-5 The intelligent cockpit test bench provided in this embodiment includes a main body 1, which has an openable suitcase structure. Specifically, the main body 1 includes a lid 11 and a body 12. The lid 11 is hinged to the body 12. The test equipment is integrated into the lid 11 and the body 12 respectively. Before the test, the lid 11 is rotated to display the internal test equipment so that demonstration information can be displayed during the test. After the test is completed, the lid 11 is rotated in the opposite direction to protect the internal test equipment and prevent accidental contact.

[0031] For example, both the lid 11 and the body 12 are made of aluminum alloy, which is strong, lightweight, and easy to move.

[0032] Preferably, please refer to Figure 1 The lid 11 and the body 12 are hinged by several hinges 13. One side of the lid 11 is hinged to one side of the body 12 along its length. One side of several hinges 13 is spaced apart and connected to one side of the lid 11 along its length. The other side of several hinges 13 is spaced apart and connected to one side of the body 12 along its length. The main body 1 is laid horizontally, and the lid 11 is rotated to open and display the testing equipment. Alternatively, one side of the lid 11 is hinged to one side of the body 12 along its width. One side of several hinges 13 is spaced apart and connected to one side of the lid 11 along its width. The other side of several hinges 13 is spaced apart and connected to one side of the body 12 along its width. The main body 1 is laid vertically, and the lid 11 is rotated to open and display the testing equipment.

[0033] In this embodiment, the intelligent cockpit test bench is designed so that, when not in testing mode, the cover 11 and the housing 12 are locked together by a lock to prevent accidental opening and damage to the test equipment.

Figure 2 When the main body 1 is closed, the two female buckles 14 and the two male buckles 15 are engaged one-to-one, thereby locking the lid 11 and the body 12.

[0034] In other embodiments, the number of female buckles 14 and male buckles 15 can be other, as long as the female buckles 14 and male buckles 15 correspond one-to-one. In addition, multiple female buckles 14 can be installed at intervals on multiple side walls of the cover 11 (excluding the side where the hinge 13 is installed), and multiple male buckles 15 can be installed at intervals on multiple side walls of the body 12 (excluding the side where the hinge 13 is installed).

[0035] Preferably, a pull rod 16 is installed on one side of the main body 1, and the pull rod 16 is installed on at least one of the lid 11 and the body 12. Multiple casters 17 are installed at intervals on the opposite side of the main body 1, and the casters 17 are installed on at least one of the lid 11 and the body 12. In this embodiment, the pull rod 16 is installed on one side opposite to the main body along its length, and the multiple casters 17 are installed at intervals on the other side opposite to the main body along its length. When the main body 1 is in an upright position, gripping the pull rod 16 and dragging it causes the casters 17 to rotate, thus moving the main body 1.

[0036] More preferably, a handle 18 is installed on at least one side of the main body 1. That is, a handle 18 is installed on at least one side opposite each other in the width direction, and the handle 18 is installed on at least one of the lid 11 and the body 12; or, a handle 18 is installed on at least one side opposite each other in the length direction, and the handle 18 is installed on at least one of the lid 11 and the body 12; or, a handle 18 is installed on both at least one side opposite each other in the width direction and at least one side opposite each other in the length direction, and the handle 18 is installed on at least one of the lid 11 and the body 12, which facilitates moving the main body 1.

[0037] The integrated testing equipment in main body 1 includes a display screen 21, a speaker 22, a DC voltage and current tester 23, a CAN signal simulator, and an ACC switch button 25. The specific connection relationships and functions are as follows:

[0038] The speaker 22 is connected to the audio interface of the car under test, the DC voltage and current tester 23 and the CAN signal simulator through a standardized interface. On the one hand, it tests the audio effect of the car, and on the other hand, it receives signals from the DC voltage and current tester 23 and the CAN signal simulator. When the DC voltage and current tester detects an abnormal voltage or current, it plays an alarm sound to remind the user to check the power system. When the CAN signal simulator detects a communication failure, it plays an alarm sound to remind the user to check the communication line.

[0039] The DC voltage and current tester 23 is configured to monitor the power status of the vehicle under test in real time.

[0040] The CAN signal simulator is connected to the smart cockpit system of the vehicle under test to simulate operating conditions and generate CAN bus signals to test the functionality of the smart cockpit system.

[0041] The ACC switch button 25 is connected to the ACC switch interface of the car to control the opening and closing of the ACC power supply of the car under test.

[0042] The display screen 21 is connected to the speaker 22, the DC voltage and current tester 23, the CAN signal simulator, and the ACC switch button 25, and is used to display the real-time status of the speaker 22 and the ACC switch button 25, as well as the test information of the DC voltage and current tester 23 and the CAN signal simulator.

[0043] Please see Figure 1 and Figure 5 The display screen 21 and the speaker 22 are integrated on the cover 11. The display screen 21 is installed at the mounting point in the middle area of ​​the inner cavity of the cover 11 and is flush with the inner side of the cover 11. The speaker 22 is installed in the inner cavity of the cover 11 to facilitate the display of test information. The DC voltage and current tester 23, the CAN signal simulator and the ACC switch button 25 are integrated on the enclosure 12 for easy operation.

[0044] In addition, the enclosure 12 also integrates a power socket 26 and a power switch. The power socket 26 is used to connect an external power source, thereby supplying power to the display screen 21, speaker 22, DC voltage and current tester 23 and CAN signal simulator through a multi-channel drive circuit. The power switch is configured to control the on and off of the multi-channel drive circuit to control each device.

[0045] Accordingly, this embodiment provides a speaker section for the speaker 22. Specifically, the speaker section is located on the inner plate of the cover 11 and communicates with the inner cavity. The speaker 22 faces the speaker section, which includes a plurality of sound outlet holes 111. The sound from the speaker 22 is transmitted through the sound outlet holes 111.

[0046] Please see Figure 5 Four speakers 22 are installed at intervals inside the cavity of the cover 11, with two speakers 22 located on the left side of the display screen 21 and the other two speakers 22 located on the right side of the display screen 21. The inner plate of the cover 11 is provided with four speaker units, and the four speaker units correspond to the four speakers 22 respectively. In other feasible embodiments, the number and distribution of speakers 22 are not fixed, as long as the speakers 22 correspond one-to-one with the speaker units.

[0047] For example, the DC voltage and current tester 23 includes a DC voltmeter, a DC ammeter, and a voltage and current display screen. The DC voltmeter and DC ammeter are installed inside the cavity of the housing 12, and the voltage and current display screen is embedded in the inner plate of the housing 12. The DC voltmeter and DC ammeter are connected to the voltage and current display screen. The DC voltmeter is configured to monitor the voltage value of the DC circuit in the vehicle under test in real time, and the DC ammeter is configured to monitor the current value of the DC circuit in the vehicle under test in real time. The voltage and current display screen is used to receive the detection information from the DC voltmeter and DC ammeter and to visually display the voltage value measured by the DC voltmeter and the current value measured by the DC ammeter.

[0048] Before measurement, disconnect the power supply of the car's power system to ensure safe operation. Locate the power line (positive) and ground line (negative). Connect the positive probe of the DC voltmeter to the power line and the negative probe to the ground line. Connect the DC ammeter in series with the power line of the car's power system. Reconnect the power supply of the car's power system and start the DC voltmeter and DC ammeter to monitor the voltage and current values ​​of the DC circuit in the car under test in real time.

[0049] Furthermore, the inner panel of the enclosure 12 integrates a standardized USB interface 27. The USB interface 27 is connected to the voltage and current display screen, and external devices can connect to the voltage and current display screen through the USB interface 27 to read the stored data.

[0050] For example, the CAN signal simulator includes a CAN signal simulation operation screen 241, a CAN bus, and a standardized CAN interface 242. The CAN signal simulation operation screen 241 is embedded in the inner panel of the housing 12, and the CAN interface 242 is integrated into the inner panel of the housing 12. The CAN interface 242 is connected to the CAN signal simulation operation screen 241 and is connected to the intelligent cockpit system of the vehicle under test through the CAN bus. By operating the CAN signal simulation operation screen 241, CAN bus signals are simulated and generated to simulate various working conditions and fault situations, and transmitted to the intelligent cockpit system through the CAN bus to test the performance of the intelligent cockpit system and receive test information.

[0051] Optionally, please refer to Figure 1 and Figure 4 The inner panel of the housing 12 has heat dissipation holes 121. The number of heat dissipation holes 121 is unlimited. The heat dissipation holes 121 are connected to the inner cavity of the housing 12, so as to dissipate heat in time and prevent the main body 1 from getting too hot.

[0052] Further, please refer to Figure 4 The housing 12 has a storage compartment 122 for storing circuits or equipment required for testing. To prevent them from falling out, a cover 123 is provided to open and close the storage compartment 122. For example, slide rails are provided on opposite sides of the storage compartment 122, and the cover 123 is slidably connected to the two slide rails. The cover 123 slides along the slide rails to cover or open the storage compartment 122.
