[0036] The purpose of the present application is to provide a motor fixing structure 100 to solve the technical problems in the related art that the motor and the bracket structure of the electric toothbrush are prone to misalignment.

[0037] The motor fixing structure 100 includes a motor 10, an anti-foolproofing member 20 and a bracket assembly 30. The motor 10 is a cylindrical motor, and the motor 10 includes a top surface, a bottom surface and an annular side surface around the outer periphery of the top surface and the bottom surface, and the output shaft of the motor 10 passes through the top surface. The anti-foolproofing member 20 is arranged on the top surface of the motor 10 and is fixed to the motor 10. The anti-foolproofing member 20 includes a lug portion 202, and the lug portion 202 protrudes in the circumferential direction relative to the annular side surface in a direction away from the axis of the motor 10. The bracket assembly 30 is provided with a receiving cavity, and the receiving cavity is used to receive the motor 10 and the anti-foolproofing member 20. The inner wall of the receiving cavity is provided with a groove portion 33, and the groove portion 33 is used to receive the lug portion 202, so that the lug portion 202 and the anti-foolproofing member 20 are circumferentially limited relative to the bracket assembly 30.

[0038] The motor fixing structure 100 provided in this embodiment can be applied to an electric toothbrush, which includes a toothbrush head and the motor fixing structure 100. The toothbrush head is connected to the output shaft of the motor 10. The motor 10 drives the toothbrush head to vibrate at high frequency through the output shaft to clean the user's oral cavity. In other embodiments, the motor fixing structure 100 can also be applied to other machine devices that need to install the motor 10, and this application does not limit this. The electric toothbrush provided in this embodiment includes a motor fixing structure 100 and a toothbrush head, but this does not mean that the electric toothbrush can only include the above structure. The electric toothbrush can also include a shell, a battery core assembly, etc. The shell is used to accommodate the motor fixing structure 100 to prevent the motor 10 and other structural parts from being damaged or corroded by external water vapor. The battery core assembly is used to electrically connect the motor 10 and supply energy to the motor 10 so that the motor 10 can work normally.

[0039] The foolproofing member 20 is disposed on the top surface of the motor 10 and is fixed to the motor 10. Specifically, the foolproofing member 20 is provided with a first through hole 21, and the first through hole 21 is used to pass the output shaft of the motor 10 so that the output shaft of the motor 10 can pass through the foolproofing member 20. In addition, the foolproofing member 20 is also provided with a first mounting through hole 22, and the first mounting through hole 22 is arranged adjacent to the first through hole 21. Similarly, the motor 10 is provided with a first mounting hole 11 corresponding to the first mounting through hole 22 on one side (the top surface) facing the foolproofing member 20, and the first mounting hole 11 and the first mounting through hole 22 are fixed by a first fastener. In this embodiment, the first fastener is a screw, and the first fastener is provided with an external thread, and the inner wall of the first mounting hole 11 is provided with an internal thread, and the first fastener is threadedly matched with the first mounting hole 11, so that the first fastener is axially fixed relative to the motor 10, thereby making the foolproofing member 20 axially fixed relative to the motor 10. Optionally, in the present embodiment, the number of the first mounting through holes 22 and the first mounting holes 11 is 4, and the 4 first mounting through holes 22 are arranged around the first through hole 21, and the number of the first fasteners is 4, and the four sides of the anti-foolproofing member 20 are fixed to the motor 10, which can further improve the fixing firmness between the anti-foolproofing member 20 and the motor 10, and avoid the anti-foolproofing member 20 from being separated from the motor 10. In other embodiments, the number of the first mounting through holes 22 and the first mounting holes 11 can also be 1, or 2, or 3, or 5, or more than 5, and the first fastener can also be 1, or 2, or 3, or 5, or more than 5, and the present application does not limit this. It should be noted that the number of the first fastener and the first mounting hole 11 can be the same or different, and it should not be understood as a limitation on the present application.

[0040] Furthermore, a receiving groove 23 is provided on the foolproofing member 20, and the receiving groove 23 is provided on the side of the foolproofing member 20 away from the motor 10, and the receiving groove 23 is provided around the first through hole 21, and the first mounting through hole 22 is provided on the bottom wall of the receiving groove 23, and the bottom wall of the receiving groove 23 is used to abut and limit the first fastener. In the axial direction of the motor 10, the size of the receiving groove 23 is larger than the size of the head of the first fastener, so that the head of the first fastener can be received in the receiving groove 23, and the first fastener is prevented from protruding relative to the foolproofing member 20, which can improve the flatness of the side of the foolproofing member 20 away from the motor 10 after the foolproofing member 20 is fixed to the motor 10, so that it can adapt to more other limiting structures. Similarly, the number of the receiving grooves 23 is set corresponding to the number of the first mounting through holes 22.

[0041] The foolproofing member 20 includes a lug portion 202, the radial dimension of which is greater than the radial dimension of the annular side surface. In other words, the lug portion 202 protrudes in the circumferential direction relative to the annular side surface in a direction away from the axis of the motor 10. In other words, in the axial direction of the motor 10, the distance between the orthographic projection of the lug portion 202 and the axis of the motor 10 is greater than the distance between the annular side surface and the axis of the motor 10. Specifically, the foolproofing member 20 includes a main body portion 201 and a lug portion 202, the main body portion 201 is arranged corresponding to the top surface of the motor 10, and the radial dimension of the main body portion 201 is the same as or similar to the radial dimension of the motor 10, the first through hole 21 and the first mounting hole 11 are arranged on the main body portion 201, and the lug portion 202 protrudes in a radial direction away from the axis of the foolproofing member 20 along the outer periphery of the main body portion 201.

[0042] The motor fixing structure 100 further includes the bracket assembly 30, and a receiving cavity is provided in the bracket assembly 30, and the receiving cavity is used to receive the motor 10 and the foolproof component 20. It should be noted that the bracket assembly 30 can not only be used to receive the motor 10 and the foolproof component 20, but also can be used to receive the battery core assembly or fix the circuit board and other structures, and the present application does not limit this.

[0043] Specifically, in the bracket assembly 30, the inner wall of the receiving cavity is provided with a groove portion 33, the shape of the groove portion 33 corresponds to the lug portion 202, and the groove portion 33 is used to receive the lug portion 202, so that the lug portion 202 and the foolproof member 20 are circumferentially limited relative to the bracket assembly 30. In other words, when the lug portion 202 is provided in the groove portion 33, the groove wall of the groove portion 33 abuts against the lug portion 202, and the groove wall of the groove portion 33 can limit the lug portion 202 to prevent the lug portion 202 from moving, thereby preventing the foolproof member 20 from rotating or moving in the receiving cavity. It should be noted that, when the lug portion 202 is disposed in the groove portion 33, the bracket assembly 30 can not only limit the anti-idiot component 20 circumferentially to prevent the anti-idiot component 20 and the motor 10 from rotating relative to the bracket assembly 30, but the bracket assembly 30 can also limit the anti-idiot component 20 and the motor 10 axially and radially to prevent the anti-idiot component 20 and the motor 10 from axially or radially moving relative to the bracket assembly 30.

[0044] Optionally, in this embodiment, the number of the lugs 202 is 4, and the 4 lugs 202 are evenly spaced around the body 201, and similarly, the number of the grooves 33 is also 4. The number of the lugs 202 and the grooves 33 is 4, so that the four corners of the foolproofing member 20 can be fixed, so as to further improve the fixing effect of the foolproofing member 20 in the bracket assembly 30.

[0045] In the motor fixing structure 100 provided in the present application, the anti-idiot component 20 is arranged on the top surface of the motor 10 and is fixed to the motor 10. The lug portion 202 of the anti-idiot component 20 protrudes in the circumferential direction relative to the annular side surface in a direction away from the axis of the motor 10. The accommodating cavity of the bracket assembly 30 is used to accommodate the motor 10 and the anti-idiot component 20. The inner wall of the accommodating cavity is provided with the groove portion 33 for accommodating the lug portion 202, so that the lug portion 202 and the anti-idiot component 20 are circumferentially limited relative to the bracket assembly 30, which can avoid the problem of misalignment between the motor 10 and the bracket assembly 30 during vibration, thereby improving the installation firmness of the motor 10 so that the motor 10 can work normally.
