Embodiment 1

[0070] A vehicle door for performance verification, including a test vehicle door 50, a vehicle door frame 51, an internal and external adjustment door frame 52, a front and rear adjustment door frame 53, and a bottom plate 54;

[0071] The test car door is hinged on the car door frame 51 and can be fixed on the car door frame 51 by a locking mechanism. When the test car door 50 is closed, it is in sealing contact with the car door frame 51;

[0072] The door frame 51 is fixedly connected to the inner and outer adjustment door frame 52;

[0073] The top of the inside and outside adjustment door frame 52 is connected to the top of the front and rear adjustment door frame 53 by the rotating shaft 65 to adjust the inside and outside inclination angle of the car door 50 under test, the bottom of the inside and outside adjustment door frame 52 and the bottom of the front and rear adjustment door frame 53 can pass The adjustment and locking assembly is fixed to fix the internal and ...

Embodiment 2

[0087] A vehicle cabin verification platform, comprising a vehicle cabin body, on which two opposite vehicle doors for performance verification as described in Embodiment 1 are assembled.

[0088] As preferably, the vehicle cabin body is a volume-adjustable vehicle cabin, and the volume-adjustable vehicle cabin includes a head compartment assembly part 9, at least two vehicle cabin assembly parts 10, and any two vehicle cabin assembly parts 10 , and any one of the cabin assembly parts 10 and the head cabin assembly part 9 can be sealed and connected to each other, the front cabin assembly part 10 is sealed by the front cabin assembly part 9, and the rearmost cabin assembly part 10 is replaced by The tail end wall 11 is sealed, and the air pressure regulating device for the cabin is sealed and assembled on the replaceable tail end wall 11 .

[0089]The replaceable rear end wall 11 is used as the rear end wall to make the cabin form a closed space, completely simulating the cabi...

Embodiment 3

[0104] In order to adjust the angle of the cabin body, the cabin verification platform described in Embodiment 2 is mounted on the chassis frame assembly.

[0105] The chassis frame assembly includes a bottom beam 35, angled outrigger assemblies 36 symmetrically arranged on the four corners at the bottom of the bottom beam 35, and two sets of symmetrically arranged axle assemblies 37 assembled at the bottom of the bottom beam 35, Each group of axle assemblies 37 includes an axle welded body 38 for supporting the bottom beam 35, a shock-absorbing universal wheel structure 39 assembled on the bottom of both ends of the axle welded body 38, and fixed on the axle. The socket 40 is supported by jacks at both ends of the welded body 38 .

[0106] When the modular air pressure adjustable cabin verification platform needs to simulate the inclination angle, the inclination angle outrigger assembly 36 is used as a support to maintain balance, and the axle assembly 37 is used for moving ...

Abstract

The invention discloses a vehicle door for performance verification and a vehicle cabin verification platform. The vehicle door for performance verification comprises a tested vehicle door, a vehicle door frame, an inner-outer adjusting door frame, a front-back adjusting door frame and a bottom plate. The tested vehicle door is hinged to the vehicle door frame and can be fixed to the vehicle door frame through a locking mechanism, and when the tested vehicle door is closed, the tested vehicle door makes sealing contact with the vehicle door frame. The vehicle door frame is fixedly connected to the inner-outer adjusting door frame; the top of the inner-outer adjusting door frame is connected to the top of the front-back adjusting door frame through a rotating shaft to adjust the inner-outer inclination angle of the tested vehicle door. Centering arc blocks are fixed to the outer edge of the front-back adjusting door frame, arc-shaped sliding rails are fixed to the inner edge of the bottom plate, the centering arc blocks and the arc-shaped sliding rails are arranged in a one-to-one correspondence mode, and the outer arc faces of the centering arc blocks are matched with the inner arc faces of the arc-shaped sliding rails to adjust the front-back inclination angle of the tested vehicle door. The vehicle door can incline forwards, backwards, inwards and outwards and can be used for verifying various test parameters of the vehicle door.

Description

technical field [0001] The invention relates to the technical field of aerodynamic testing in a door opening and closing chamber, in particular to a vehicle door and cabin verification platform for performance verification. Background technique [0002] In recent years, with the rapid development and wide application of various assisted driving technologies, automobiles have gradually evolved from a means of transportation to a part of people's daily lives. The comfort of the interior environment of automobiles increasingly determines the consumption trend of the public. Therefore, it is very necessary to conduct a more comprehensive verification of the reliability of the body performance to improve the comfort of the car. The quality and inclination angle of the car door will affect the comfort of the internal environment, but the verification system for the performance of the car door is lacking in the prior art. Contents of the invention [0003] The purpose of the pre...
