[0002] With the development of the automobile industry, people have higher and higher requirements for automobile functions. As an important component in the automobile thermal management system, the cooling fan is required to have a higher air volume and efficiency, and at the same time, lower noise. The current cooling fan blades adopt a high-speed blade layout, which has high noise and affects the comfort of the whole vehicle.

In addition, the traditional fan blade installation and disassembly process is cumbersome and requires special tools and professionals, which is not conducive to the user's daily use and maintenance. Therefore, it is necessary to improve the prior art;

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a novel fan blade that reduces vibration. Figure 1-2 A novel fan blade for reducing jitter includes a housing 1, a rectangular cavity 4 is arranged in the housing 1, a rectangular plate 5 is slidably connected between the left and right inner walls of the rectangular cavity 4, a control switch 6 is installed on the front side of the rectangular plate 5, a mounting cavity 9 is opened in the rectangular plate 5, a fan body 10 is installed in the mounting cavity 9, the fan body 10 is connected to the control switch 6 by signal, the fan body 10 is composed of a plurality of blades, the shape design of the fan blade adopts aerodynamic principles, optimizes the shape and angle of the blade, so as to reduce the air resistance when the fan is running and reduce the jitter during operation, and a mounting mechanism for the fan body 10 is arranged in the housing 1;

[0023] The mounting mechanism includes wedge-shaped grooves 11 symmetrically opened on the outer walls of the left and right sides of the rectangular plate 5, two slide grooves 13 are symmetrically arranged in the housing 1, and the two slide grooves 13 are connected to the adjacent wedge-shaped grooves 11. The two slide grooves 13 are horizontally arranged with pull rods 2, and the opposite surfaces of the two pull rods 2 are respectively provided with wedge blocks 12, and one side of the two wedge blocks 12 is provided with a limited position opening;

[0024] Reference Figure 2-4 The opposing surfaces of the two pull rods 2 extend into the corresponding limit openings and are rotatably connected to the inner walls of the corresponding limit openings. The inner diameters of the two limit openings are smaller than the two pull rods 2, so that the two pull rods 2 can pull the entire wedge block 12 when moving relative to each other. A threaded layer 15 is provided on the two pull rods 2, and two threaded holes matching the threaded layer 15 are provided in the shell 1. The two wedge blocks 12 match the corresponding wedge grooves 11. The ends of the two wedge blocks 12 away from the fan body 10 are elastically connected to the inner walls of the corresponding slide grooves 13 through connecting springs 14. The ends of the two pull rods 2 away from the fan body 10 extend to both sides of the shell 1 and are fixedly connected with pull rings 3.

[0025] When the fan body 10 needs to be disassembled, the pull rod 2 is first rotated by the pull ring 3 to release the limit of the wedge block 12, and then the two pull rings 3 are pulled by hand to make the two pull rods 2 move away from each other, so that the two wedge blocks 12 leave the corresponding wedge grooves 11. At this time, under the action of gravity, the rectangular plate 5 will drive the fan body 10 to fall, and the disassembly is completed. When installing, it is only necessary to move the rectangular plate 5 upward so that the limit block 8 at the upper end of the rectangular plate 5 enters the limit groove 7. When the rectangular plate 5 moves up, the two wedge blocks 12 will move away from each other. When the rectangular plate 5 moves up to the point where the wedge block 12 is facing the corresponding wedge groove 11, the two wedge blocks 12 will be stuck in the corresponding wedge groove 11, and it is convenient to complete the limit disassembly and installation.

[0026] Reference Figure 1 A limiting groove 7 is provided on the inner top of the rectangular cavity 4 , and a limiting block 8 matching the limiting groove 7 is fixedly connected to the upper end of the rectangular plate 5 .

[0027] The implementation principle of a novel fan blade for reducing jitter in the embodiment of the present application is as follows: when the device is in normal use, the appearance design of the fan blade adopts aerodynamic principles to optimize the shape and angle of the blade to reduce the air resistance when the fan is running and reduce the jitter during operation;

[0028] In the initial state, the two wedge blocks 12 fit tightly with the corresponding wedge grooves 11. When the fan body 10 needs to be disassembled, first rotate the pull rod 2 through the pull ring 3 to release the limit on the wedge block 12, and then pull the two pull rings 3 by hand to make the two pull rods 2 move away from each other, so that the two wedge blocks 12 leave the corresponding wedge grooves 11. At this time, under the action of gravity, the rectangular plate 5 will drive the fan body 10 to fall, and the disassembly is completed. When installing, you only need to move the upward rectangular plate 5 so that the limit block 8 at the upper end of the rectangular plate 5 enters the limit groove 7. When the rectangular plate 5 moves up, the two wedge blocks 12 will move away from each other. When the rectangular plate 5 moves up to the point where the wedge block 12 is facing the corresponding wedge groove 11, the two wedge blocks 12 will be stuck in the corresponding wedge groove 11, and it is relatively convenient to complete the limit disassembly and installation.
