Problems solved by technology

The hood actuator and the trunk lid actuator need to be installed or adjusted to the corresponding positions, and the workload is very heavy for continuous debugging, resulting in a relatively low construction efficiency of the test platform, and because the material of the aluminum alloy profile is soft, each connection Repeated disassembly and assembly of the locking bolts in the part will cause damage to the profile

Embodiment 1

[0037] The present invention provides such Figure 1-6 The four-door and two-cover endurance test bench for automobiles shown includes a main body frame 1, and a door opening and closing mechanism 2 and a car cover opening and closing mechanism that can be adjusted in translation along the frame are provided on the frames on both sides of the main body frame 1. Agency 3;

[0038] The rectangular frame 201 of the door opening and closing mechanism 2 is arranged on two side-by-side poles at the lower end of the main frame 1, and the lower side of the rectangular frame 201 is fixed with a U-shaped bolt A4 through a nut, and when the nut is tightened, The U-shaped bolt A4 hooks the two poles and the bottom side of the rectangular frame 201 and presses them. When the nut of the U-shaped bolt A4 is unscrewed, the door opening and closing mechanism 2 is pulled along the two poles arranged side by side at the lower end of the main frame 1. Move and adjust the position; adjust the pos...

Embodiment 2

[0051] Such as Figure 7 as shown,

[0052] The difference from Embodiment 1 is that both the first drive deflection mechanism 202 and the second drive deflection mechanism 32 are composed of a servo motor 11 and a reducer 12, and the output shaft of the servo motor 11 is connected to the output shaft of the reducer 12 The shaft is fixedly connected. The drive is used to replace the pneumatic, and the electric has the advantages of simplified structure, accurate parking, random acceleration and deceleration, strong controllability, and low noise.

Abstract

The invention discloses an automobile four-door two-cover durability test bench, which comprises a main body rack, wherein frames on the two sides of the main body rack are provided with an automobiledoor opening and closing mechanism and an automobile cover opening and closing mechanism which can translate along the frames to adjust positions; the automobile door opening and closing mechanism iscomposed of a rectangular frame fixedly installed at the bottom of the main body rack, a first driving deflection mechanism arranged in the rectangular frame, a rotating cross beam A fixedly installed at the output end of the first driving deflection mechanism, a supporting vertical rod and a sliding door assembly, and the automobile cover opening and closing mechanism is composed of a supportingframe, a second driving deflection mechanism, a rotating cross beam B, a steel pipe and an adjustable cover pulling assembly arranged on the steel pipe. According to the durability test bench, a plurality of adjusting nodes are designed for the automobile door opening and closing mechanism and the automobile cover opening and closing mechanism, it is guaranteed that the positions of all components are adjusted more conveniently and efficiently, the building efficiency of the test platform is improved, and equipment assembling is conducted through U-shaped bolts, so that aluminum alloy profiles are replaced with square pipes, and the strength and fatigue resistance of the whole rack are higher.

Description

technical field [0001] The invention belongs to the technical field of automobile test equipment, and in particular relates to an automobile durability test bench with four doors and two covers. Background technique [0002] The side door of a passenger car is what we often call the door, and the front and rear covers are the hood (engine cover) and the trunk (trunk). Since there are four side doors and two front and rear covers, they are collectively referred to as four doors and two covers. Because it involves the safety of drivers and passengers, there are many tests on door covers, among which the test of four doors and two covers is also The necessary equipment in the laboratory of the automobile factory. During the test, the fatigue strength test will be carried out on all relevant components, and the pass or fail judgment will be made according to the national standard or enterprise standard. The quality of the door lock, the quality of the door hinge, the strength of...
