[0001] This application belongs to the technical field of automotive model wind tunnel test structures, and particularly relates to a rapid replacement structure for automotive model wind tunnel test specimens. Background Art

[0002] The cost of the wind tunnel center is charged per second. For automotive model wind tunnel tests, there are many specimen replacement scenarios. If the specimen replacement is not convenient enough, it will lead to an increase in the overall cost. Currently, specimen replacement is achieved by bolt locking, which damages the specimen's shape, is complex to operate, and time-consuming. Summary of the Invention

[0003] The purpose of this application is to overcome the defects of the prior art and provide a rapid replacement structure for automotive model wind tunnel test specimens. The entire set of mechanisms is convenient, simple, fast in replacement, and accurate in positioning, which helps to reduce the cost of automotive model wind tunnel tests.

[0004] To achieve the above objective, this application adopts the following technical solutions:

[0005] A rapid replacement structure for automotive model wind tunnel test specimens includes a body and a specimen detachably arranged on the body; a first groove is provided on the body, and a first magnet is fixedly arranged at the bottom of the first groove in the first groove;

[0006] A positioning post is provided on the specimen, a second groove is provided on the positioning post, the second groove is located at the end of the positioning post, and a second magnet is fixedly arranged in the second groove;

[0007] The positioning post is inserted into the first groove, and the second magnet is adsorbed and fixed to the first magnet.

[0008] In one solution, the body is a console body, and the specimen is a console armrest.

[0009] In one solution, the first groove is a conical groove, and the positioning post is a conical positioning post.

[0010] In one solution, the second groove is a dovetail groove, and the outer contour of the second magnet matches the dovetail groove.

[0011] In one solution, the first magnet is fixed to the first groove by bonding.

[0012] This application has the following positive effects:

[0013] When replacing the specimen of the rapid replacement structure for automotive model wind tunnel test specimens, the operation is simple, time-consuming is avoided, and the time for manual assembly and replacement of the specimen is greatly reduced.

[0014] In addition, it can more completely reflect the shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following embodiments given in conjunction with the drawings further illustrate the specific embodiments of the present application. The present application is not limited to the descriptions of the following embodiments.

[0020] As shown in Attached Figure 1 and 2 A quick replacement structure for a sample 2 in a wind tunnel test of a car model includes a body 1 and a sample 2 detachably arranged on the body 1; a first groove 11 is arranged on the body 1, and a first magnet 3 is fixedly arranged in the first groove 11, and the first magnet 3 is located at the bottom of the first groove 11. A positioning post 4 is arranged on the sample 2, a second groove 41 is arranged on the positioning post 4, the second groove 41 is located at the end of the positioning post 4, and a second magnet 5 is fixedly arranged in the second groove 41. The positioning post 4 is inserted into the first groove 11, and the second magnet 5 is adsorbed and fixed with the first magnet 3.

[0021] When the sample 2 needs to be replaced, only the sample 2 needs to be removed, and then the new sample 2 is inserted into the body 1 to complete the replacement. During the process, the positioning post 4 is inserted into the first groove 11 to directly complete the positioning of the sample 2. Finally, the second magnet 5 and the first magnet 3 are adsorbed to each other under the action of magnetic force to complete the fixation. The overall structure removes the bolt locking structure, is simple to operate, does not consume time, and greatly reduces the time for manual assembly and replacement of the sample 2. In addition, it can more completely reflect the shape.

[0022] In one embodiment, the body 1 is a console body, and the sample 2 is a console armrest.

[0023] In one embodiment, there is no drawing in this embodiment. The first groove 11 is a conical groove, and the positioning post 4 is a conical positioning post 4, which is convenient for the first groove 11 and the positioning post 4 to be closely combined when connected.

[0024] Referring to Attached Figure 3As shown, in one embodiment, the second groove 41 is a dovetail groove 6, and the outer contour of the second magnet 5 matches the dovetail groove 6. The dovetail groove 6 can effectively prevent the second magnet 5 from accidentally falling off during the replacement and removal of the sample 2. In one embodiment, the first magnet 3 and the first groove 11 are fixed by bonding.

[0025] The above content is a further detailed description of the present application in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, several simple deductions or substitutions can be made, which should all be regarded as belonging to the protection scope of the present application.
