[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] To address the cumbersome assembly process of existing grille motors, this invention provides a grille motor mounting structure. The grille motor includes a brushless motor, a circuit board, several transmission gears, and an output shaft. The circuit board is electrically connected to the brushless motor and can be connected to external control equipment to transmit control signals to the brushless motor. The brushless motor is connected to the output shaft through the transmission of the various transmission gears, which drive the output shaft to rotate. The grille motor mounting structure simplifies the installation of the grille motor and reduces its installation cost by limiting and locking the brushless motor.

[0037] It should be noted that the grid motor mounting structure described in this utility model is used for, but not limited to, the installation of grid motors. For ease of explanation, this utility model only uses the application of the grid motor mounting structure to a grid motor as an example. The principle of the grid motor mounting structure applied to other types of equipment is essentially the same as that applied to a grid motor, and will not be described in detail here.

[0038] The grid motor mounting structure provided in this embodiment of the utility model is as follows: Figure 1-3 As shown, it includes a bottom shell 10, a top cover 20, and an annular mounting bracket 30. The top cover 20 covers the bottom shell 10 and surrounds the bottom shell 10 to form a mounting cavity 21. The annular mounting bracket 30 is located in the mounting cavity 21 and fixed to the bottom shell 10. The annular mounting bracket 30 forms a limiting mounting groove 31, which is used to install a motor. The annular mounting bracket 30 has several spaced locking interfaces 32 along its circumference, and each locking interface 32 is used to lock the motor.

[0039] Specifically, the grid motor mounting structure comprises a bottom shell 10, a top cover 20, and an annular mounting bracket 30. The top cover 20 covers the bottom shell 10 and together with the bottom shell 10 forms a mounting cavity 21. The bottom shell 10 and the top cover 20 together form the outer shell structure of the grid motor. The outer shell structure can accommodate the motor and the transmission components connected to the motor. The annular mounting bracket 30 is located in the mounting cavity 21 and fixed to the bottom shell 10. A limiting mounting groove 31 is formed on the inner side of the annular mounting bracket 30. The stator of the grid motor can be installed in the limiting mounting cavity 21 for limiting and positioning. Since the annular mounting bracket 30 has several spaced locking interfaces 32 in the circumferential direction, each locking interface 32 can accommodate the protruding structure on the surface of the stator, thereby achieving the stability of the stator. With the above-mentioned mounting structure of the grid motor, when installing the grid motor, it is only necessary to install the motor in the limiting mounting groove 31 and insert the protruding structure on the surface of the motor into the locking interface 32, thus facilitating the assembly of the grid motor.

[0040] In this embodiment, as Figure 2-3 As shown, the upper opening of the bottom shell 10 is provided with a mounting wall 11 extending in the circumferential direction, and the upper cover 20 is fitted into the mounting wall 11. By fitting into the upper cover 20, the upper cover 20 is limited and stably connected with the upper cover 20.

[0041] In this embodiment, as Figure 1-3 As shown, the bottom shell 10 is provided with a 4-pin connector 12, which is used for external connector connection to transmit control signals to the circuit board.

[0042] In one embodiment, such as Figure 1-3 As shown, a first fixing bracket 13 and a second fixing bracket 14 are respectively provided at both ends of the bottom shell 10. The first fixing bracket 13 is provided with a first fixing hole 131, and the second fixing bracket 14 is provided with a second fixing hole 141 with a different orientation than the first fixing hole 131. Specifically, the grille motor mounting structure is fixed to the intake grille bracket through the first fixing bracket 13 and the second fixing bracket 14 of the bottom shell 10. During the fixing process, fasteners pass through the first fixing hole 131 and the second fixing hole 141 and connect to the intake grille bracket to fix the bottom shell 10. Since the first fixing hole 131 and the second fixing hole 141 have different orientations, the bottom shell 10 can be fixed in different fixing directions to improve the stability of the connection between the bottom shell 10 and the grille bracket.

[0043] In this embodiment, as Figure 1-3 As shown, there are two first fixing brackets 13, which are located on both sides of the insertion interface 12.

[0044] In this embodiment, as Figure 3As shown, the brushless motor 70 has several snap-fit ​​protrusions 71 on the outer circumference of the stator. During the installation of the brushless motor 70, the snap-fit ​​protrusions 71 snap into the snap-fit ​​interface 32, thereby stabilizing the brushless motor 70.

[0045] In one embodiment, such as Figure 2-3 As shown, each card interface 32 has a limiting wall 33 on both sides, and each limiting wall 33 is fixed to the annular mounting bracket 30 and extends in the radial direction of the annular mounting bracket 30. Specifically, by setting the limiting wall 33 on both sides of the card interface 32, the radial length of the card interface 32 can be increased, thereby clamping the snap-fit ​​protrusion 71 of the brushless motor 70 and thus better limiting the brushless motor 70.

[0046] In one embodiment, such as Figure 2-3 As shown, at least one end of the limiting wall 33 away from the annular mounting bracket 30 is connected to the side wall of the mounting cavity 21. Specifically, the connection between the partially limiting wall 33 and the side wall of the mounting cavity 21 strengthens the connection between the annular mounting bracket 30 and the bottom shell 10, reducing the vibration of the brushless motor 70 during operation.

[0047] In one embodiment, such as Figure 2-3 As shown, the annular mounting bracket 30 is also provided with several spaced positioning ports 34 in the circumferential direction, each positioning port 34 for positioning the stator. Specifically, the stator of the brushless motor 70 is also provided with several positioning brackets 72 in the circumferential direction. When the stator of the brushless motor 70 is installed on the annular mounting bracket 30, the positioning brackets 72 of the stator of the brushless motor 70 are installed in the positioning ports 34 to position the brushless motor 70. At the same time, the snap-fit ​​protrusions 71 on the outside of the stator snap into the snap-fit ​​interface 32 to stabilize the stator.

[0048] In one embodiment, such as Figure 2As shown, the bottom wall of the bottom shell 10 has a first limiting frame 15, which extends toward the upper cover 20. The upper cover 20 has a second limiting frame 22, which is disposed opposite to the first limiting frame 15 and extends toward the first limiting frame 15. A limiting opening is formed between the second limiting frame 22 and the first limiting frame 15, and the limiting opening is provided for limiting the output gear 91. Specifically, the bottom shell 10 and the top cover 20 are provided with mounting holes. The output shaft 90 of the grid motor is installed in the mounting holes. The output shaft 90 of the grid motor is provided with an output gear 91. The first limiting frame 15 and the second limiting frame 22 abut against the upper and lower sides of the output gear 91, thereby axially limiting the output shaft 90 and ensuring the stability of the output shaft 90. When installing the output shaft 90, it is only necessary to insert the output shaft 90 into the mounting hole of the bottom shell 10, so that the output gear 91 of the output shaft 90 abuts against the first positioning frame 72, and then close the cover, so that the second limiting frame 22 limits the upper side of the output gear 91, and finally realizes the installation of the output shaft 90, which facilitates the installation of the output shaft 90.

[0049] In one embodiment, such as Figure 2-3 As shown, the mounting structure also includes a first positioning shaft 40, which is coaxially arranged with the annular mounting bracket 30 and fixed to the bottom shell 10 for mounting the rotor. Specifically, when installing the motor rotor, it is only necessary to mount the rotor onto the first positioning shaft 40. The first positioning shaft 40 can position the rotor of the brushless motor 70. By being coaxially arranged with the annular mounting bracket 30, the coaxial installation of the rotor and stator of the brushless motor 70 is ensured, thereby facilitating the assembly of the brushless motor 70.

[0050] In one embodiment, such as Figure 2-3 As shown, the mounting structure also includes several second positioning shafts 50, each located in the mounting cavity 21 and fixed to the bottom shell 10, for mounting the transmission gear 80. Specifically, when installing the transmission gear 80, it is only necessary to mount the transmission gear 80 onto the first positioning shaft 40. The second positioning shafts 50 provide positioning for the installation of each transmission gear 80, ensuring precise fit of each transmission gear 80, thereby facilitating the assembly of the transmission gear 80.

[0051] In one embodiment, such as Figure 1-3 As shown, the mounting structure also includes a sealing ring 60. The bottom shell 10 and the top cover 20 are provided with opposing sealing ports 23. The sealing ring 60 is installed in the sealing port 23 to seal both ends of the output shaft 90. Specifically, the sealing ring 60 can seal the output shaft 90 with the bottom shell 10 and the top cover 20, thereby improving the sealing performance of the housing.

[0052] This utility model also provides a grid motor, such as Figure 3As shown, the device includes a brushless motor 70 and the aforementioned grille motor mounting structure. The brushless motor 71 is inserted into the limiting mounting slot 31. The brushless motor 70 has a snap-fit ​​protrusion 71, which snaps into the snap-fit ​​interface 32. Specifically, by setting the above-mentioned mounting structure, the grille motor can be easily assembled, reducing the assembly cost.

[0053] In this embodiment, as Figure 3 As shown, the grid motor also includes a circuit board, several transmission gears 80 and an output shaft 90. The brushless motor 70 includes a stator and a rotor. The snap-fit ​​protrusion 71 is provided in the circumferential direction of the stator. The stator is installed in the limiting mounting groove 31. The rotor is located inside the stator and is sleeved on the first positioning shaft 40. The circuit board is electrically connected to the stator and can be connected to an external control unit through the plug interface 12. Each transmission gear 80 is respectively sleeved on each second positioning shaft 50. The output shaft 90 is rotatably connected to the mounting hole and is axially limited by the first limiting frame 15 and the second limiting frame 22.

[0054] In this embodiment, the stator of the brushless motor 70 is also provided with several positioning frames 72 along the circumferential direction. When the stator of the brushless motor 70 is installed on the annular mounting frame 30, the positioning frames 72 of the stator of the brushless motor 70 are installed in the positioning port 34 to position the brushless motor 70. At the same time, the snap-fit ​​protrusion 71 on the outside of the stator snaps into the snap-fit ​​interface 32 to stabilize the stator.

[0055] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail as follows: When assembling the grid motor, the rotor part of the brushless motor 70 of the grid motor is sleeved on the first positioning shaft 40, the stator part of the brushless motor 70 is installed in the limiting mounting groove 31, and the outer snap-fit ​​protrusion 71 is snapped into the snap-fit ​​interface 32. Then, the transmission gear 80 is sleeved on each of the second positioning shafts 50, the output shaft 90 is installed in the mounting hole, and then the upper cover 20 is closed, which facilitates the assembly of the grid motor.
