[0030] It should be noted that, in the description of this utility model, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0031] Example: Combination Figure 1-2 As shown, this embodiment discloses an intelligent vehicle system testing device, including:

[0032] The storage box 1 includes two hinged shells 11 connected by a hinge, so the shells 11 are made of space steel. The two shells 11 rotate relative to the hinge to open and close the storage box 1. The symmetrical arrangement of the two shells 11 increases the storage area of ​​the storage box 1, allowing the test equipment to be embedded in the plane as much as possible, facilitating observation during testing. A handle 12 is provided on the separated side of the shell 1. When the storage box 1 is closed, the two handles 12 fit together, making it easy to carry.

[0033] A buffer positioning member 2 is fixedly connected to the shell 11, and the buffer positioning member 2 is made of anti-collision sponge material. The anti-collision sponge has low density, good softness, strong toughness, and good shock absorption performance, which can reduce the impact caused by collision and prevent objects from being damaged. The buffer positioning member 2 is provided with a plurality of positioning grooves 21, and the positioning grooves 21 are used to embed test equipment such as wireless AP3, Raspberry Pi 4 and switch 5. It should be noted that the positioning grooves 21 are configured to match the shape of the wireless AP3, Raspberry Pi 4 or switch 5, and the positioning grooves 21 wrap the five sides of the wireless AP3, Raspberry Pi 4 or switch 5 to provide sufficient protection for the wireless AP3, Raspberry Pi 4 or switch 5. The width of the positioning slot 21 increases gradually from the side away from the buffer positioning member 2 toward the buffer positioning member 2. That is, the inner side of the positioning slot 21 is an inclined surface from top to bottom and from inside to outside. This solution provides pressure on the wireless AP 3, Raspberry Pi 4, and switch 5 toward the positioning slot 21, preventing them from falling off. It should be noted that the positioning slot 21 is provided with a wiring slot at the interface of the wireless AP 3, Raspberry Pi 4, and switch 5 to facilitate wiring.

[0034] The storage box 1 is also provided with a cushioning pad, which is placed between the two shells 11 when the storage box 1 is closed. The cushioning pad is used to protect the side of the wireless AP 3, Raspberry Pi 4 and switch 5 that is exposed to the positioning groove 21.

The Raspberry Pi 4's low price makes it even more versatile.

[0037] The switch 5 is an Ethernet switch, which transmits data based on Ethernet, a local area network that uses a shared bus transmission medium. Each port on an Ethernet switch is directly connected to a host, and typically operates in full-duplex mode. The switch can connect many pairs of ports simultaneously, allowing each pair of communicating hosts to transmit data without conflict, as if they had exclusive access to the communication medium.

[0038] The anti-collision sponge can be made of a material mixed with polyethylene and cotton fiber. This material combines the toughness and elasticity of polyethylene with the energy absorption of cotton fiber, can effectively absorb and disperse the impact force, and reduce the impact and damage caused by the collision.

[0039] Optionally, the anti-collision sponge may also be a special nano-cotton for anti-collision soft packs using polyurethane foam as the main material. Polyurethane foam has excellent strength and wear resistance and can effectively resist collisions and impacts.

The computer is installed with host computer software. The staff inputs the test requirements according to the actual situation. The host computer can start the corresponding wireless AP 3 and Raspberry Pi 4 according to the test requirements to perform the test. For example, when testing a sample without Bluetooth and hotspot, only six Raspberry Pi 4s need to be started. However, when testing a sample with Bluetooth and hotspot, eight Raspberry Pi 4s need to be started.

[0041] A cable duct 6 is provided in the storage box 1, and the cable duct 6 is embedded in the buffer positioning member 2 and arranged along the edge of the storage box 1. The cable duct 6 is used to centrally process the wiring harness, so that the entire device remains beautiful and neat.

[0042] Optionally, the receiving box 1 is provided with a relay interface 12 , one end of the relay interface located inside the receiving box 1 is connected to the switch 5 via a first cable 131 , and the other end of the relay interface located outside the receiving box 1 is used to connect to the computer.
