Description

Technical Field

[0001] This application belongs to the field of electric toothbrush technology and relates to an electric toothbrush motor fixing structure. Background Technology

[0002] With the rapid development of electric toothbrush technology, performance optimization and structural design of its core driving component, the micro-vibration motor, have become key to enhancing product competitiveness. Current electric toothbrushes generally employ an integrated injection-molded motor support structure, fixing the motor inside the handle housing through large-area wrapping or bonding.

[0003] A certain gap is reserved between the mechanism support and the handle shell to avoid forming a rigid vibration transmission channel, which would cause the high-frequency vibration energy of the motor to be directly transmitted to the surface of the shell through the contact surface. On the other hand, a design that uses a large area of ​​the mechanism support to wrap around and fix the motor inside the handle shell would result in an excessively large handle shell, affecting grip comfort and reducing the user experience. Utility Model Content

[0004] To overcome the problems existing in the related technology, this application aims to provide an electric toothbrush motor fixing structure that can reduce the area of ​​the motor fixing bracket to reduce the volume of the handle housing.

[0005] This application is achieved through the following technical solution.

[0006] This technical solution provides an electric toothbrush motor fixing structure, used to fix the motor inside the handle housing in conjunction with the motor mechanism bracket, including:

[0007] The substrate has a first support on its first side and two symmetrical second supports on the same side as the first support. The first support and the two second supports together define a mounting groove for engaging with the outside of the motor.

[0008] The second side of the substrate is provided with a support plate, and the tail end of the support plate is provided with a positioning plate. The support plate and the positioning plate together form a snap-fit ​​structure to cooperate with the movement bracket limiting motor.

[0009] The substrate is mounted inside the mounting slot of the mechanism bracket by a fixture.

[0010] This technical solution uses a fixed structure and a mechanism bracket to fix the motor together, and leaves a gap between the motor and the handle housing so that they do not come into contact with each other. This reduces the volume of the mechanism bracket and forms a relationship in which the fixed structure and the mechanism bracket jointly define the position of the motor, thereby reducing the volume required for the handle housing to cover the mechanism bracket.

[0011] The present invention is further configured such that the positioning plate extends along the corresponding position of the inner wall of the handle housing, and there is a predetermined distance between its outer contour surface and the inner wall, so as to form an avoidance distance between the motor and the handle housing.

[0012] The present invention is further configured such that a reinforcing plate is provided on the second side of the substrate, and the reinforcing plate is fixedly connected to the support plate.

[0013] The present invention is further configured such that the reinforcing plate has two symmetrical plates about the substrate, and is configured as a triangular plate structure.

[0014] The present invention is further configured such that at least one reserved groove is provided on the substrate, the reserved groove being used to reduce resonance.

[0015] The present invention is further configured such that the support plate is provided with at least one through groove structure, the through groove is provided through the thickness direction of the support plate, and its groove width is configured to allow internal wiring to pass through.

[0016] The present invention is further configured such that the fixing device consists of two symmetrical fixing screws on the substrate.

[0017] The present invention is further configured such that the fixing device is glue.

[0018] The present invention is further provided with a spring on the outside of the fixing screw, the spring being used to prevent the fixing screw from loosening.

[0019] The present invention is further configured such that a clearance space is formed between the first bracket and the two second brackets relative to the fixing screw, the clearance space being used for installing the fixing screw.

[0028] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0030] This embodiment discloses an electric toothbrush motor fixing structure, used to fix the motor 12 inside the handle housing 1 in conjunction with the motor bracket 11, such as... Figures 1-5 As shown, it includes:

[0031] The substrate 2 has a first support 21 on its first side and two symmetrical second supports 22 on the same side as the first support 21. The first support 21 and the two second supports 22 together define a mounting groove to be snapped onto the outside of the motor 12.

[0032] A support plate 23 is provided on the second side of the base plate 2, and a positioning plate 24 is provided at the tail end of the support plate 23. The support plate 23 and the positioning plate 24 together form a snap-fit ​​structure to cooperate with the movement bracket 11 to limit the motor 12.

[0033] The substrate 2 is mounted inside the mounting slot of the mechanism bracket 11 by means of the retainer 26.

[0034] It should be noted that the protruding part at the tail end of the motor 12 is fixed by a mounting groove defined by the first bracket 21 and the two second brackets 22. The tail end of the motor 12 is fixed by a buckle structure formed by the support plate 23 and the positioning plate 24. This achieves the limitation of one side of the motor 12 by the mechanism bracket 11 and the limitation of the other side of the motor 12 by the fixing structure. Since the fixing structure replaces the mechanism bracket 11 to limit the motor 12, the volume of the mechanism bracket 11 is further reduced, thereby reducing the volume required for the handle shell 1 to cover the mechanism bracket 11.

[0035] like Figures 1-4 As shown, the positioning plate 24 extends along the corresponding position of the inner wall of the handle housing 1, and there is a predetermined distance between its outer contour surface and the inner wall, so that a predetermined clearance distance is formed between the motor 12 and the handle housing 1.

[0036] It should be noted that the positioning plate 24 replaces the mechanism bracket 11 to limit the motor 12, reducing the volume of the mechanism bracket 11 required to fix the motor 12, and thus reducing the volume of the handle housing 1.

[0037] like Figure 4 As shown, a reinforcing plate 25 is provided on the second side of the substrate 2, and the reinforcing plate 25 is fixedly connected to the support plate 23.

[0038] As shown in Figure 4, the reinforcing plate 25 has two symmetrical plates about the base plate 2 and is configured as a triangular plate structure.

[0039] It should be noted that the reinforcing plate 25 is used to improve the structural strength.

[0040] like Figure 4 and Figure 5 As shown, at least one reserved groove 27 is provided on the substrate 2, and the reserved groove 27 is used to reduce resonance.

[0041] It should be noted that by setting structures such as holes and slots, the vibration characteristics of the structure can be changed, reducing the noise and vibration generated when the motor 12 is working.

[0042] like Figures 1-5 As shown, the support plate 23 is provided with at least one through groove structure. The through groove is arranged through the thickness direction of the support plate, and its width is configured to allow internal wiring to pass through.

[0043] like Figure 4 and Figure 5 As shown, the fixture 26 consists of two symmetrical fixing screws on the base plate 2.

[0044] like Figures 1-5 As shown, the fastener 26 is made of glue.

[0045] It should be noted that the fixing structure can be fixed to the movement bracket 11.

[0046] like Figures 1-5 As shown, a spring is provided on the outside of the fixing screw 26 to prevent the fixing screw 26 from loosening.

[0047] like Figure 5 As shown, a clearance space is formed between the first bracket 21 and the two second brackets 22 relative to the fixing screw 26, and the clearance space is used to install the fixing screw 26.

[0048] Working principle: The motor 12 is fixed by the fixed structure and the mechanism bracket 11 working together, and the motor 12 and the handle housing 1 are separated by a gap and do not contact each other. This can reduce the volume of the mechanism bracket 11 and form a relationship in which the fixed structure and the mechanism bracket 11 jointly limit the position of the motor 12, so as to reduce the volume required for the handle housing 1 to cover the mechanism bracket 11.

[0049] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
