[0022] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0023] The following describes in detail, with reference to the accompanying drawings, a fan oscillating motor fixing structure according to an embodiment of the present invention.

[0024] For easier understanding, please refer to Figures 1 to 4 An embodiment of a fan oscillating motor fixing structure provided by this utility model includes a front inner shell 4 and a rear inner shell 5, between which a stepper motor 6 and a reducer 7 are installed, and a motor fixing structure is provided between the front inner shell 4, the rear inner shell 5 and the stepper motor 6.

[0025] The motor fixing structure includes a limiting block 801, a front motor fixing groove 802, a first limiting groove 803, a rear motor fixing groove 804, and a second limiting groove 805. The limiting block 801 is fixedly connected to both sides of one end of the stepper motor 6. The front motor fixing groove 802 is opened on the inner side of one end of the front inner shell 4. The first limiting groove 803 is opened on the side wall of the front motor fixing groove 802. The rear motor fixing groove 804 is opened on the inner side of one end of the rear inner shell 5. The second limiting groove 805 is opened on the side wall of the rear motor fixing groove 804. The shape of the stepper motor 6 matches the shape of the front motor fixing groove 802 and the rear motor fixing groove 804. The stepper motor 6 is located inside the front motor fixing groove 802 and the rear motor fixing groove 804. The shape of the limiting block 801 matches the shape of the first limiting groove 803 and the second limiting groove 805, and one end of the limiting block 801 is located inside the first limiting groove 803 and the second limiting groove 805, respectively.

[0026] It should be noted that by opening a front motor fixing groove 802, a first limiting groove 803, a rear motor fixing groove 804, and a second limiting groove 805 in the front inner shell 4 and the rear inner shell 5, and setting a limiting block 801 connected to one end side wall of the stepper motor 6, the stepper motor 6 is clamped by the front motor fixing groove 802 and the rear motor fixing groove 804, and the stepper motor 6 is limited by the cooperation of the limiting block 801 with the first limiting groove 803 and the second limiting groove 805, preventing it from rotating relative to the front inner shell 4 and the rear inner shell 5, reducing the space redundancy between the shell and the motor, and improving the compactness of the equipment structure.

[0027] In some embodiments, such as Figure 1As shown, the reducer 7 is fixedly installed on the top of the stepper motor 6. One end of the output shaft of the stepper motor 6 is fixedly installed on one end of the input shaft of the reducer 7. The outer shell 3 is fixedly installed on the outer side of the front inner shell 4 and the rear inner shell 5. The rocker arm 2 is rotatably connected to the top inner side of the front inner shell 4 and the rear inner shell 5. One end of the bottom of the rocker arm 2 is fixedly installed on one end of the output shaft of the reducer 7. The fan body 1 is fixedly installed on the top of the rocker arm 2. The bottom of the outer shell 3 is provided with a support frame 9. The support frame 9 is in the shape of an inverted T. The top of the outer shell 3 and the support frame 9 are threaded together.

[0028] It should be noted that the stepper motor 6 drives the reducer 7, which in turn drives the rocker arm 2 to make the fan body 1 oscillate. The support frame 9 is used to support and place the motor.

[0029] Working principle: During installation, the stepper motor 6 is clamped by the front motor fixing slot 802 and the rear motor fixing slot 804. At the same time, the stepper motor 6 is limited by the cooperation of the limiting block 801 with the first limiting slot 803 and the second limiting slot 805, preventing it from rotating relative to the front inner shell 4 and the rear inner shell 5. This structure greatly reduces the distance between the shell and the motor, reduces the space redundancy between the shell and the motor, and improves the compactness of the equipment structure.
