Description

Technical Field

[0001] This utility model relates to the field of electric toothbrush technology, and in particular to an electric toothbrush shock-absorbing bracket. Background Technology

[0002] Electric toothbrush holders integrate core components such as vibrating motors, circuit boards, control switches, and batteries, assembling them into the handle housing and ultimately combining with the toothbrush head to form a complete electric toothbrush. However, the high-amplitude vibrations generated by the vibrating motor are directly transmitted to the handle, resulting in noticeable vibrations when the user holds it, affecting the user experience. Current technologies commonly use manual assembly of shock-absorbing pads to mitigate vibrations, but this method suffers from drawbacks such as low assembly efficiency, high labor costs, and insufficient stability. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art by providing an electric toothbrush shock-absorbing bracket. By directly injection molding the shock-absorbing pad onto the bracket body, the assembly efficiency can be improved and the stability is also better.

[0004] This utility model discloses an electric toothbrush shock-absorbing bracket, including a bracket body, on which a battery compartment and a motor compartment are provided. The bracket body is characterized in that: a plug-in cavity is provided at the bottom of the motor compartment, and an elastic shock-absorbing pad is injection molded on the bracket body. The elastic shock-absorbing pad is located at the bottom of the motor compartment and wraps around the inner wall of the plug-in cavity. An elastic expansion pad is injection molded on the side wall of the battery compartment, and the elastic expansion pad protrudes from the side wall of the battery compartment.

[0005] A further feature of this invention is that a circuit board mounting compartment is provided on the opposite side of the battery compartment on the bracket body, and a positioning hole is provided through the circuit board mounting compartment and the battery compartment. The elastic expansion pad is located in the positioning hole and extends towards the circuit board mounting compartment to form an elastic pad protruding from the circuit board mounting compartment.

[0006] A further feature of this invention includes a first positioning groove located at the outer edge of the battery compartment and a second positioning groove located at the outer edge of the motor compartment. The elastic expansion pad portion is located in the first positioning groove to form a first elastic contact pad, and the front and rear sides of the first elastic contact pad are exposed and raised to form a first contact portion. The elastic shock-absorbing pad portion is located in the second positioning groove to form a second elastic contact pad, and the front and rear sides of the second elastic contact pad are exposed and raised to form a second contact portion.

[0007] A further feature of this invention is that the bracket body has power connection holes at both ends of the battery compartment.

[0008] A further feature of this invention is that the elastic expansion pads at the positive and negative end faces of the battery compartment protrude outward to form expansion strips, and the top of the expansion strips is inclined to form a guide surface.

[0009] The specific beneficial effects of this utility model are as follows: When in use, the vibration motor can be partially assembled into the insertion cavity. During operation, the elastic shock-absorbing pad can play a role in shock absorption. At the same time, the elastic tightening pad can tighten the battery to prevent it from shaking. This can improve the stability of the battery and avoid the noise generated by the battery shaking, thus achieving the effect of shock absorption and noise reduction. Attached Figure Description

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model. The elastic shock-absorbing pad and the elastic expansion pad are preferably made of rubber material, but of course, other elastic materials can also be used.

[0021] This utility model discloses an electric toothbrush shock-absorbing bracket, including a bracket body 1. The bracket body 1 is provided with a battery compartment 2 and a motor compartment 3. In this utility model embodiment, the bracket body 1 is provided with a plug-in cavity 4 at the bottom of the motor compartment 3, and the bracket body 1 is injection molded with an elastic shock-absorbing pad 5. The elastic shock-absorbing pad 5 is located at the bottom of the motor compartment 3 and wraps around the inner wall of the plug-in cavity 4. The bracket body 1 is injection molded with an elastic expansion pad 6 on the side wall of the battery compartment 2, and the elastic expansion pad 6 protrudes from the side wall of the battery compartment 2.

[0022] Using the above technical solution, the vibration motor can be partially assembled into the insertion cavity 4 during use. When working, the elastic shock-absorbing pad 5 can play a role in shock absorption. At the same time, the elastic tightening pad 6 can tighten the battery to prevent it from shaking. This can improve the stability of the battery and avoid the noise generated by the battery shaking, thus achieving the effect of shock absorption and noise reduction.

[0023] The bracket body 1 has a circuit board mounting compartment 7 on the opposite side of the battery compartment 2. It also includes a positioning hole 8 that penetrates the circuit board mounting compartment 7 and the battery compartment 2. The elastic expansion pad 6 is located in the positioning hole 8 and extends towards the circuit board mounting compartment 7 to form an elastic pad 9 protruding from the circuit board mounting compartment 7. The positioning hole 8 can increase the stability of the elastic expansion pad 6 during injection molding, facilitate demolding, and the elastic pad 9 can play a role in shock absorption and noise reduction for the circuit board.

[0024] It also includes a first positioning groove 10 located at the outer edge of the battery compartment 2 and a second positioning groove 11 located at the outer edge of the motor compartment 3. The elastic expansion pad 6 is located in the first positioning groove 10 to form a first elastic contact pad 12. The first elastic contact pad 12 has its front and rear sides exposed and raised to form a first contact portion 13. The elastic shock-absorbing pad 5 is located in the second positioning groove 11 to form a second elastic contact pad 14. The second elastic contact pad 14 has its front and rear sides exposed and raised to form a second contact portion 15. When the bracket body 1 is assembled as a whole and inserted into the handle of the electric toothbrush, the first contact portion 13 and the second contact portion 15 can abut against the inner wall of the handle. The use of elastic contact can play a role in noise reduction and shock absorption.

[0025] The bracket body 1 has power connection holes at both ends of the battery compartment 2, which facilitates the connection of the battery to the circuit board later.

[0026] The elastic tension pads 6 at the positive and negative end faces of the battery compartment 2 protrude outward to form tension strips 16. The top of the tension strips 16 is inclined to form a guide surface 17. The tension strips 16 fix the two ends of the battery with uniform radial tension force to prevent loosening. At the same time, the guide surface 17 provides guidance for battery assembly, which significantly improves installation efficiency.
