[0046] The embodiments of the present utility model refer to Figure 1-Figure 5 As shown, a motor module and an electric toothbrush are provided.

[0047] In the related art, the motor mounting base 100 is generally a rigid part, and the motor assembly 200 is mounted on the motor mounting base 100. The vibration generated by the motor assembly 200 during operation will be transmitted to the rigid motor mounting base 100, and then transmitted to the body of the electric toothbrush, resulting in a strong vibration feeling, loud noise, and a poor user experience.

[0048] According to an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 According to the embodiment of the utility model, the motor module includes a motor mounting base 100, which is formed with a mounting cavity; a motor assembly 200, which is arranged in the mounting cavity, and a first shock absorber 300 is arranged on at least two opposite sides of the motor assembly 200, and at least part of the first shock absorber 300 abuts between the motor mounting base 100 and the motor assembly 200.

[0049] It is understood that, in this embodiment, taking an electric toothbrush as an example, the motor mounting base 100 is used to stably mount the motor assembly 200, and the motor mounting base 100 can be made of a solid material to provide sufficient support and stability to ensure that the motor assembly 200 can be properly installed and operated. The types of the motor assembly 200 include, but are not limited to, a DC motor, a brushless DC motor, or a linear motor.

[0050] Optionally, the motor mounting base 100 can be made of materials such as ABS (acrylonitrile butadiene styrene), PC (polycarbonate), PA (polyamide), aluminum alloy, etc., and the first shock absorber 300 can be made of TPU (thermoplastic polyurethane), rubber or silicone, which has good elasticity and shock absorbing properties and can effectively absorb shock and vibration.

[0051] It should be noted that the types of the first shock absorber 300 include but are not limited to spring shock absorbers, rubber shock absorbers, pneumatic shock absorbers, shock absorbing washers, liquid shock absorbers and coil spring shock absorbers, etc. For cost considerations, the following embodiments all use shock absorbing washers as examples to illustrate the shock absorbers.

[0052] Shock-absorbing pads can effectively absorb and disperse vibration energy, reduce vibration transmission, reduce the vibration amplitude of the structure, and improve the shock-absorbing effect. Shock-absorbing pads can play a buffering role when subjected to impact force, reduce the damage caused by impact, and extend the service life of equipment or structures; they can also reduce the transmission of noise caused by vibration and impact, and reduce the noise generated during the operation of the motor module; some shock-absorbing pads also have anti-slip functions, which can increase the friction between components, while reducing the possibility of vibration and sliding, and improving the installation stability with the motor assembly 200.

[0053] According to the motor module of the embodiment of the utility model, the motor module includes a motor mounting seat 100 and a motor assembly 200, the motor mounting seat 100 is formed with an installation cavity, the motor assembly 200 is arranged in the installation cavity, at least two opposite sides of the motor assembly 200 are provided with a first shock absorbing member 300, and the two sides of the first shock absorbing member 300 are respectively abutted with the motor mounting seat 100 and the motor assembly 200. By providing the first shock absorbing member 300 on at least two opposite sides of the motor assembly 200, at least part of the first shock absorbing member 300 abuts between the motor mounting seat 100 and the motor assembly 200, so that the motor assembly 200 and the motor mounting seat 100 do not directly contact each other, the motor assembly 200 is completely isolated from the motor mounting seat 100, and the motor assembly 200 is suspended relative to the motor mounting seat 100, which can avoid the vibration of the motor assembly 200 from being transmitted to the motor mounting seat 100 to the greatest extent, thereby improving the shock absorbing effect of the motor module, reducing noise, and improving the user experience.

[0054] In an optional embodiment, first shock absorbing members 300 are disposed around the motor assembly 200 to further improve the shock absorbing effect of the motor assembly 200 .

[0055] According to an embodiment of the present invention, the first shock absorbing member 300 is an integrated structure, and the first shock absorbing member 300 is sleeved on the outer side of the motor assembly 200 .

[0056] It can be understood that in the present embodiment, the first shock absorber 300 is designed as an integrated structure, and the first shock absorber 300 is mounted on the outside of the motor assembly 200, which can provide a better shock absorption effect, simplify the assembly process of the first shock absorber 300, reduce the number of parts and assembly steps, improve production efficiency and reduce costs. At the same time, mounting the first shock absorber 300 on the outside of the motor assembly 200 can increase the stability and reliability of shock absorption, reduce the risk of shock absorption failure due to the falling off of the first shock absorber 300, and effectively utilize space to avoid adding additional installation space, making the overall size of the motor module more compact.

[0057] According to one embodiment of the present invention, referring to Figure 1-Figure 3 The first shock absorber 300 is a split structure, and the first shock absorber 300 includes a front shock absorber pad 310 and a rear shock absorber pad 320 that are relatively arranged, and a top shock absorber pad 330 and a bottom shock absorber pad 340 that are relatively arranged. The front shock absorber pad 310, the rear shock absorber pad 320, the top shock absorber pad 330 and the bottom shock absorber pad 340 are arranged on the outer surface of the motor assembly 200.

[0058] It is understandable that in this embodiment, the first shock absorbing member 300 is designed as a split structure, including a front shock absorbing pad 310, a rear shock absorbing pad 320, a top shock absorbing pad 330 and a bottom shock absorbing pad 340, which are relatively arranged and sleeved on the outside of the motor assembly 200. The split structure allows each shock absorbing pad to be individually designed and adjusted to meet the shock absorption requirements of different parts. Different shock absorbing pads can be optimized for different vibration directions and frequencies to improve the shock absorption effect. By relatively arranging the front, rear, top and bottom shock absorbing pads, the vibration propagation of the motor assembly 200 can be reduced in all directions, and the vibration amplitude transmitted to the motor mounting seat 100 can be reduced, thereby improving the shock absorption performance.

[0059] Exemplarily, the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 can be arranged relatively along the extension direction of the output shaft of the motor assembly 200, and the top shock-absorbing pad 330 and the bottom shock-absorbing pad 340 are arranged on the side opposite to the extension direction of the output shaft. For example, the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 can be cylindrical and respectively sleeved on the front and rear ends of the motor assembly 200. By arranging the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 along the extension direction of the output shaft, and arranging the top shock-absorbing pad 330 and the bottom shock-absorbing pad 340 on the side opposite to the extension direction of the output shaft, an all-round shock-absorbing effect can be achieved, and vibration propagation can be effectively reduced.

[0060] Optionally, the structures of the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 may be the same or different, and the structures of the top shock-absorbing pad 330 and the bottom shock-absorbing pad 340 may be the same or different.

[0061] According to one embodiment of the present invention, referring to Figure 1-Figure 3 A gap is provided between at least two of the front shock absorbing pad 310 , the rear shock absorbing pad 320 , the top shock absorbing pad 330 and the bottom shock absorbing pad 340 .

[0062] It can be understood that in the present embodiment, by setting intervals between each shock absorbing pad, an independent shock absorbing area can be created, so that each shock absorbing pad can better play its shock absorbing role, reduce mutual interference, and improve the overall shock absorbing effect. The vibration can be more effectively dispersed to different shock absorbing areas, reducing the impact of local vibration on the overall system and improving the shock absorbing effect. The independent shock absorbing area and interval settings help to enhance the stability of the product, reduce unnecessary vibration transmission, and improve the performance and reliability of the product at work.

[0063] On the other hand, setting the interval can provide more space for the shock-absorbing pad to deform. In actual work, when the electric toothbrush vibrates, the shock-absorbing pad needs to be able to give full play to its elasticity and shock-absorbing effect. By setting the interval, it can be ensured that the shock-absorbing pad has enough space to deform and compress when subjected to force, which helps to increase the compressible range of the shock-absorbing pad, thereby more effectively absorbing and damping vibrations, making the shock-absorbing pad better adapted to vibrations of different frequencies and amplitudes, thereby improving the overall shock-absorbing effect.

[0064] According to one embodiment of the present invention, referring to Figure 1-Figure 3 The top shock-absorbing pad 330 and the bottom shock-absorbing pad 340 are both plate-shaped, and the top shock-absorbing pad 330 and the bottom shock-absorbing pad 340 are both in contact with the outer surface of the motor assembly 200 .

[0065] It is understandable that in the related art, the cross-section of the outer shell of the motor assembly 200 is generally polygonal. In the present embodiment, the top shock-absorbing pad 330 and the bottom shock-absorbing pad 340 are both designed to be plate-shaped, and the top shock-absorbing pad 330 and the bottom shock-absorbing pad 340 are fitted with the outer surface of the motor assembly 200, which can effectively reduce the gap and improve the shock-absorbing effect. It has good strength and stability, can withstand vibration and provide good shock-absorbing effect, and at the same time makes the overall structure more compact and easy to manufacture and assemble.

[0066] According to one embodiment of the present invention, referring to Figure 1-Figure 3 At least one of the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 is interference-fitted with the motor assembly 200 .

[0067] It can be understood that in the present embodiment, by interference fitting at least one of the front-end shock-absorbing pad 310 and the rear-end shock-absorbing pad 320 on the motor assembly 200, a tighter connection can be achieved, and the friction and resistance can be increased, so that the connection between the front-end shock-absorbing pad 310 and the rear-end shock-absorbing pad 320 and the motor assembly 200 is more secure, thereby improving the stability and rigidity of the entire structure and avoiding loosening or falling off of the front-end shock-absorbing pad 310 and the rear-end shock-absorbing pad 320, which may lead to shock absorption failure.

[0068] According to one embodiment of the present invention, referring to Figure 3 and Figure 4 The front shock-absorbing pad 310 and the rear shock-absorbing pad 320 are annular, and the inner circle of at least one of the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 is provided with a first protrusion 350, and the first protrusion 350 is suitable for abutting against the motor assembly 200.

[0069] It is understandable that in this embodiment, by providing the first protrusion 350 on the front shock absorbing pad 310 or the rear shock absorbing pad 320, the first protrusion 350 contacts the motor assembly 200, and the design of the first protrusion 350 can make the contact point concentrated on the protrusion part rather than the entire surface, thereby reducing the contact area between the front shock absorbing pad 310 and the rear shock absorbing pad 320 and the motor assembly 200, so that the front shock absorbing pad 310, the rear shock absorbing pad 320 and the motor assembly 200 can be aligned and installed more easily. Reducing the contact area can also reduce the friction resistance during installation, making the installation process smoother.

[0070] In an optional embodiment, a first protrusion 350 is provided on both the front shock-absorbing pad 310 and the rear shock-absorbing pad 320, and both the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 are formed with folded edges to achieve abutment between the ends of the front shock-absorbing pad 310 and the rear shock-absorbing pad 320 and the motor assembly 200.

[0071] According to one embodiment of the present invention, referring to Figure 3 and Figure 4 There are multiple first protrusions 350 , and the multiple first protrusions 350 are arranged at intervals along the circumference of the motor assembly 200 .

[0072] It can be understood that in this embodiment, by providing a plurality of first protrusions 350, and two adjacent first protrusions 350 are arranged at intervals, the intervals can provide space for the deformation of the first protrusions 350. When the first protrusions 350 are squeezed by the vibration from the vibration source (such as the motor assembly 200), the first protrusions 350 deform toward the intervals to absorb and release most of the vibration; at the same time, the intervals can also be used as sound absorbing chambers to absorb some noise. Therefore, the formation of a plurality of first protrusions 350 has a better shock absorption effect than the shock absorption method of an overall plane form.

[0073] The embodiment of the second aspect of the utility model refers to Figure 1-Figure 3 , provides an electric toothbrush, including a shell 400, a movement bracket 500 and a motor module of any of the above embodiments, the motor mounting base 100 is arranged on the movement bracket 500, and the motor mounting base 100 and the movement bracket 500 are located on both sides of the motor assembly 200.

[0074] It can be understood that in the present embodiment, the movement bracket 500 is used to provide structural support and enhance stability for the electric toothbrush, ensuring that the various components of the electric toothbrush, such as the battery and the control circuit, can be correctly installed and maintain relative positions, thereby ensuring the normal operation of the toothbrush. The assembled motor module can be installed on the movement bracket 500 through the motor mounting base 100. The movement bracket 500 and the motor mounting base 100 can enclose a mounting cavity for accommodating the motor assembly 200. By placing the motor mounting base 100 and the movement bracket 500 on both sides of the motor assembly 200, the weight and vibration of the motor can be effectively dispersed, thereby reducing the impact on the overall structure and improving the reliability and comfort of the toothbrush.

[0075] In an optional embodiment, the motor mounting base 100 and the movement bracket 500 are fixedly connected. This design can provide a more stable support structure, ensure a close connection between the motor module and the movement bracket 500, thereby reducing the risk of loosening or falling off, and can effectively prevent problems caused by loose connections during use. In another optional embodiment, the motor mounting base 100 and the movement bracket 500 are detachably connected, which facilitates the operation of repairing and replacing the motor module. Through the detachable connection, the user can easily disassemble the motor module for maintenance or replacement, which improves the maintainability and ease of use of the electric toothbrush and makes maintenance work more convenient and efficient. Those skilled in the art can design according to specific needs and application scenarios, and this embodiment does not specifically limit this.

[0076] According to one embodiment of the present invention, referring to Figure 1-Figure 3 A second shock absorbing member 600 is disposed between the inner wall of the housing 400 and the movement bracket 500 , and two sides of the second shock absorbing member 600 are respectively in contact with the housing 400 and the movement bracket 500 .

[0077] It can be understood that in this embodiment, by adding a second shock absorber 600, soft contact is achieved between the movement bracket 500 and the shell 400, which can effectively reduce the transmission of vibration from the movement bracket 500 to the shell 400, reduce the vibration intensity felt by the user, and the user will feel a smoother and more comfortable vibration when using the electric toothbrush, thereby improving the comfort of using the electric toothbrush; the soft contact design can effectively protect the movement bracket 500 and other internal components, reduce damage or wear that may be caused by vibration transmission, and extend the service life of the electric toothbrush.

[0078] It can be understood that the first shock absorber 300 can reduce the vibration transmitted from the motor mounting base 100 to the movement bracket 500, and the second shock absorber 600 can reduce the vibration transmitted from the movement bracket 500 to the shell 400, thereby achieving all-round shock absorption of the electric toothbrush and further improving the shock absorption effect.

[0079] According to one embodiment of the present invention, referring to Figure 1-Figure 3 There are multiple second shock absorbing members 600 , and the multiple second shock absorbing members 600 are arranged at intervals along the length direction of the movement bracket 500 .

[0080] It can be understood that in this embodiment, by arranging multiple second shock absorbing members 600 at intervals along the length direction of the movement bracket 500, the effective area of ​​the shock absorbing material can be increased, the vibration energy can be effectively absorbed and dispersed, the shock absorbing effect can be improved, and the degree of vibration transmission to the shell 400 can be reduced. The interval arrangement of multiple second shock absorbing members 600 can make the vibration more evenly distributed on the movement bracket 500, avoiding excessive local vibration, thereby reducing the risk of vibration transmission of the movement bracket 500, increasing stability, and improving the overall shock absorbing effect.

[0081] According to one embodiment of the present invention, referring to Figure 1-Figure 3 The second shock absorbing member 600 is disposed on a side of the movement bracket 500 close to the motor assembly 200 .

[0082] It can be understood that, in this embodiment, the second shock absorber 600 can be disposed close to the motor assembly 200, which can more effectively reduce the vibration conduction in the auxiliary area of ​​the motor assembly 200 and improve the stability and comfort of the product.

[0083] The motor assembly 200 is usually the main vibration source in an electric toothbrush. Placing the second shock absorber 600 close to the motor can directly perform shock absorption treatment on the vibration source, minimize vibration conduction, and reduce the vibration impact on the movement bracket 500. Concentrating the shock absorbers in areas with greater vibration can more efficiently absorb and disperse vibration energy, improve the overall shock absorption effect, and improve the stability and comfort of the electric toothbrush.

[0084] According to an embodiment of the present invention, the second shock absorbing member 600 is an integrated structure, and the second shock absorbing member 600 is sleeved on the outside of the movement bracket 500. The integrated structure design can reduce the number of parts, simplify the assembly process, improve production efficiency, and better ensure the stability and reliability of the first shock absorbing member 300, which is conducive to better absorption and dispersion of vibration energy during vibration transmission, thereby improving the shock absorption effect.

[0085] According to one embodiment of the present invention, referring to Figure 1-Figure 3 The second shock absorbing member 600 is a split structure, and the second shock absorbing member 600 includes an upper shock absorbing pad 610 and a lower shock absorbing pad 620 that are relatively arranged. The upper shock absorbing pad 610 and the lower shock absorbing pad 620 are installed along the circumference of the movement bracket 500. The split structure allows each shock absorbing pad to be individually designed and adjusted to meet the shock absorption requirements of different parts. Different shock absorbing pads can be optimized for different vibration directions and frequencies to improve the shock absorption effect. By relatively arranging the upper shock absorbing pad 610 and the lower shock absorbing pad 620, the vibration propagation of the motor assembly 200 can be reduced in all directions, and the vibration amplitude transmitted to the motor mounting seat 100 can be reduced, thereby improving the shock absorption performance.

[0086] In an optional embodiment, the upper shock-absorbing pad 610 and the lower shock-absorbing pad 620 are arranged at the same position in the length direction of the movement bracket 500. In another optional embodiment, the upper shock-absorbing pad 610 and the lower shock-absorbing pad 620 can also be staggered at appropriate positions in the length direction to make the internal structure more compact. For example, the lower shock-absorbing pad 620 can be set on the motor mounting base 100 to minimize the overall volume of the electric toothbrush and avoid vibration being directly transmitted from the motor mounting base 100 to the shell 400.

[0087] Optionally, the structures of the upper shock absorbing pad 610 and the lower shock absorbing pad 620 may be the same or different.
