Problems solved by technology
The tooling used for air conditioner noise testing in the prior art generally meets the test requirements of one type of air conditioner. In the actual test process, nearly a hundred types of test tooling are required for different models of air conditioners, resulting in huge costs and resources. Waste; In addition, some air conditioner noise tests use hoisting operation tests. The air conditioner is hoisted to a specified height and then the noise test is performed. This test method will cause the problem of unstable placement of the air conditioner, and the experimenter needs to perform the test under the air conditioner. operation, there is a greater safety hazard

Embodiment Construction
[0020] In order to make those skilled in the art understand the present invention better, the present invention will be further described below in conjunction with specific embodiment:
[0021] like figure 1 , figure 2 and image 3 As shown, a general tooling for noise testing of automobile air conditioners includes a steerable mobile support platform 1, an air conditioner support mechanism 2 and a fan support mechanism 3; In the upper part, the fan support mechanism 3 is fixed on the side of the turnable mobile support platform 1 by bolts.
[0022] The steerable mobile support platform 1 includes a support frame 4 and universal wheels 5 with a braking function. So that it can be mounted on the mobile support platform 1 and can be freely manipulated and moved.
[0023] There are four universal wheels 5, and the four universal wheels are welded on the four corners of the support frame 4 bottoms.
[0024] The air-conditioning support 2 includes two air-conditioning main su...

The invention discloses a universal tool for measuring noise of an automobile air conditioner. The universal tool includes a steering mobile support platform, an air conditioner supporting mechanism and a draught fan mechanism; the air conditioner supporting mechanism is directly horizontally placed on the upper portion of the steering mobile support platform, and the draught fan mechanism is fixed to the side face of the steering mobile support platform. According to the universal tool, the tool use number is reduced, the overall utilization rate of the universal tool for measuring the noise of the automobile air conditioner is improved, the requirements of testing tools of various types of air conditioners, condensate fans and evaporating fans in buses in the market can be met, working personnel for testing are avoided from conducting testing below the air conditioners, the potential safety hazard is avoided, the overall cost of the universal tool for measuring the noise of the automobile air conditioner is reduced, the test requirements of various types of air conditioners and fans of automobiles are conveniently met, and air conditioner movement and installation are easily achieved. The universal tool has the advantages of being convenient to use, high in versatility, stable in structure, easy to manufacture and process and the like.
Description
technical field [0001] The invention relates to the technical field of automotive air-conditioning noise test tooling, in particular to a general tooling used for automotive air-conditioning noise testing. Background technique [0002] According to the standard test requirements of "GB / T21361-2008 Automobile Air Conditioner", the standard limits the distance between the bus air conditioner and the ground to be 2 meters, and the test point of the condensing fan and evaporating fan is 1 meter above the ground. Because there are many models of bus air conditioners, the length and width of the air conditioners are different. The tooling used for air conditioner noise testing in the prior art generally meets the test requirements of one type of air conditioner. In the actual test process, nearly a hundred types of test tooling are required for different models of air conditioners, resulting in huge costs and resources. Waste; In addition, some air conditioner noise tests use hoi...
