[0028] In the description of the utility model, it is understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the utility model.

[0029] Please refer to Figures 1-6The utility model discloses a kind of automobile electronic fan balance testing devices, including shell 1, driving motor 2 is fixedly installed in the inside of shell 1, output shaft 3 is fixedly installed in the output end of driving motor 2, mounting base 7 is fixedly installed at the top of output shaft 3, driving mechanism 4 is equipped in the top of output shaft 3 and in the mounting base 7, a plurality of adaptive fixed components 5 are equipped on driving mechanism 4, a plurality of adaptive fixed components 5 are slidably installed on mounting base 7, locking mechanism 6 is equipped on driving mechanism 4, locking mechanism 6 is installed on output shaft 3;

[0030] Driving mechanism 4 drives a plurality of adaptive fixed components 5 to be close to each other, and the locking mechanism 6 is fastened to lock the driving mechanism 4.

[0031] In the automobile electronic fan balance testing device, when the electronic fan to be tested needs to be fixed for testing, place the electronic fan to be tested on the mounting base 7, and then rotate the driving mechanism 4 by hand to drive the plurality of adaptive fixed components 5 to start moving and approach each other on the mounting base 7. During the approaching of the adaptive fixed components 5, the position can be automatically adjusted according to the size and shape of the electronic fan to be tested, so as to closely fit the mounting part of the electronic fan to be tested, thereby effectively fixing the electronic fan to be tested of different sizes. After the adaptive fixed components 5 complete the fastening action on the electronic fan to be tested, the locking mechanism 6 is then rotated by the worker with a wrench to lock the driving mechanism 4. Since the locking mechanism 6 is installed on the output shaft 3, the driving mechanism 4 and the output shaft 3 are also locked. In this way, the electronic fan is stably fixed on the output shaft 3 during testing, and displacement or loosening does not occur due to vibration of the device or other factors. The fixing requirement of the electronic fan to be tested of various sizes can be met, and the problem of single fixing structure and lack of flexibility of the traditional testing device is effectively solved. Start the driving motor 2, and the driving motor 2 drives the output shaft 3 to rotate. The rotation of the output shaft 3 drives the mounting base 7 mounted thereon to operate, and then the mounting base 7 drives the adaptive fixed components 5 and the electronic fan to be tested to rotate, and the balance test of the electronic fan to be tested can be subsequently performed.

[0032] In one embodiment, for the above-mentioned driving mechanism 4, the driving mechanism 4 includes a fixed shaft 401 fixedly installed on the output shaft 3, a rotating disc 402 rotatably installed on the outer wall of the fixed shaft 401, and a rotating groove 403 formed in the rotating disc 402.

[0033] One end of the rotating disc 402 is fixedly installed with a driving rod 404, the rotating groove 403 is arc-shaped, and the rotating groove 403 gradually extends in an arc shape from the inner ring of the rotating disc 402 to the outer ring thereof.

[0034] The adaptive fixing assembly 5 comprises a first sliding block 501 which is slidably clamped in the rotating groove 403, and a sliding block 502 fixedly installed on the top of the first sliding block 501 and slidably installed on the mounting base 7.

[0035] The mounting base 7 is provided with moving grooves for slidably installing a plurality of sliding blocks 502, and a fixed block 503 is fixedly installed on the top of the sliding block 502 and is arc-shaped at the end away from the sliding block 502.

[0036] When it is necessary to fix the automobile electronic fan for balance test, the electronic fan to be tested is placed on the mounting base 7, and the staff manually rotates the driving rod 404. The rotation of the driving rod 404 drives the rotating disc 402 connected thereto to rotate around the fixed shaft 401. Since the rotating disc 402 is provided with a special-shaped rotating groove 403 which is arc-shaped and gradually extends from the inner ring to the outer ring, the first sliding block 501 clamped in the rotating groove 403 will slide in the rotating groove 403 along with the rotation of the rotating disc 402. The sliding block 502 fixed on the top of the first sliding block 501 is limited in the moving groove of the mounting base 7 and can only linearly slide, so that the arc-shaped sliding track of the first sliding block 501 in the rotating groove 403 is converted into the linear displacement of the sliding block 502. In this process, the fixed block 503 connected to the top of the sliding block 502 also moves synchronously. The plurality of fixed blocks 503 approach or move away from each other due to the rotation of the rotating disc 402. When the plurality of fixed blocks 503 approach each other, the arc-shaped end portions thereof can adjust the positions according to the size and shape of the electronic fan to be tested and tightly fit the mounting parts of the electronic fan to be tested, thereby effectively fixing the electronic fan to be tested of different sizes and providing a stable and reliable installation basis for subsequent balance test of the automobile electronic fan, effectively solving the problem that the traditional test device is difficult to adapt to the fixation of the electronic fan to be tested of different sizes.

[0037] In one embodiment, for the above-mentioned locking mechanism 6, the locking mechanism 6 comprises a fixed disc 601 fixedly installed on the output shaft 3, an arc-shaped groove 602 is formed in the inside of the fixed disc 601, a connecting rod 603 is arranged in the inside of the arc-shaped groove 602, and one end of the connecting rod 603 is fixedly installed with the driving rod 404.

[0038] A connecting block 604 is fixedly installed on the outer surface of the connecting rod 603 and at the upper end of the fixed disc 601, and a hexagonal nut 605 is threadedly installed on the outer surface of the connecting rod 603 and at the lower end of the fixed disc 601.

[0039] When the worker manually rotates the driving rod 404 to drive the fixing block 503 to complete the fastening operation on the electronic fan to be tested, the driving rod 404 drives the connecting rod 603 connected thereto to rotate. Since the connecting rod 603 has one end located in the arc-shaped groove 602 inside the fixing disc 601, and the outer surface of the connecting rod 603 is respectively provided with the connecting block 604 and the hexagonal nut 605 on the upper and lower ends of the fixing disc 601, when the driving rod 404 rotates, the connecting rod 603 will produce relative displacement in the arc-shaped groove 602.

[0040] When the fixing block 503 reaches the appropriate fastening position of the electronic fan to be tested, the hexagonal nut 605 is moved upward along the threads of the connecting rod 603 by rotating the hexagonal nut 605 with a wrench, and the hexagonal nut 605 extrudes the lower end surface of the fixing disc 601 upward. At the same time, the connecting block 604 is limited from rotating freely in the arc-shaped groove 602 under the extrusion force of the upper and lower ends due to the abutting relationship with the upper end surface of the fixing disc 601, and further locks the position of the driving rod 404, and also locks the state of the entire driving mechanism 4. In this way, it is ensured that the entire adaptive fixing assembly 5 will not be loosened or changed in position due to external factors during the balance test of the automotive electronic fan, ensuring the stability and accuracy of the test, so that the electronic fan to be tested can receive the balance test in a reliable fixed state, avoiding the deviation of test data or test failure caused by the instability of the fixing device.
