Description

Technical Field

[0001] This utility model relates to the field of motor structure technology, specifically a small-volume motor. Background Technology

[0002] A motor, also known as an electric motor or engine, is a device that converts electrical energy, magnetic energy, or other forms of energy into mechanical energy.

[0003] Existing motors typically achieve speed reduction by using multiple gears. However, this increases the overall size of the motor, making it unsuitable for larger devices. For example, it's not suitable for smaller products or devices, such as gifts with rotating functions. As market demand has diversified holiday gifts, rotating gifts are particularly popular with both children and adults. These gifts are often small and delicate, requiring small motors to accommodate their size. Existing motors with good speed reduction capabilities are too large to meet this requirement, necessitating further structural optimization. Utility Model Content

[0004] This utility model discloses a small-volume motor to solve the technical problem of motors being too large.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following optimized technical solution:

[0006] A small-volume motor includes a drive motor, a reduction assembly, and an output gear. The output end of the drive motor is provided with a drive gear. The reduction assembly includes a first reduction gear and a second reduction gear. The large gear of the first reduction gear meshes with the drive gear, the large gear of the second reduction gear meshes with the small gear of the first reduction gear, and the output gear meshes with the small gear of the second reduction gear. The output gear and the drive gear do not contact each other and are arranged on the same axis.

[0007] Furthermore, the present invention also includes a housing, which covers the drive motor and encloses the drive gear and the reduction assembly.

[0008] Furthermore, the housing includes a lower shell and an upper cover, the lower shell having a receiving cavity, and the upper cover covering the top of the lower shell.

[0009] Furthermore, the bottom center of the lower shell is provided with a through hole for the drive tooth to pass through and a support frame for the output tooth to be placed thereon. The support frame is located above the through hole, and the top surface of the support frame is provided with a strip groove for the central shaft of the output tooth to be inserted therein. The center of the strip groove corresponds to the circle of the through hole.

[0010] Furthermore, the bottom of the lower shell is provided with two slots, which are respectively used for the central shaft of the first reduction gear and the central shaft of the second reduction gear to pass through.

[0011] Furthermore, the output tooth includes a gear portion and an output portion, which are integral structures. The gear portion is used to mesh with the second reduction gear, and the output portion is used to connect to an external structure.

[0012] Furthermore, the top of the output section protrudes from the top of the housing, and the top of the output section is provided with a positioning notch.

[0013] The present invention has the following advantages over the prior art:

[0014] The small-volume motor provided by this utility model adopts an output tooth set above the drive tooth of the drive motor. The two do not contact each other and are set on the same axis. This can save space while ensuring the same axis output, making the motor occupy a smaller area. It is suitable for devices or products that can provide a small footprint, and therefore suitable for small gifts with rotation function. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the 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.

[0024] See Figures 1-7 A small-volume motor includes a drive motor 1, a reduction assembly, and an output gear 5. The output end of the drive motor 1 is provided with a drive gear 2. The reduction assembly includes a first reduction gear 3 and a second reduction gear 4. The large gear of the first reduction gear 3 meshes with the drive gear 2, and the large gear of the second reduction gear 4 meshes with the small gear of the first reduction gear 3. The output gear 5 meshes with the small gear of the second reduction gear 4. The output gear 5 does not contact the drive gear 2 and the two are arranged on the same axis. The output gear 5 is used to connect to the structure that needs to be driven to rotate.

[0025] In the above technical solution, the drive motor 1 starts to drive the drive gear 2 to rotate synchronously. The drive gear 2 can drive the first reduction gear 3 to rotate, and the first reduction gear 3 can drive the second rotating gear to rotate, thus having the effect of two reductions. The second reduction gear 4 then drives the output gear 5 to rotate. The power after reduction is transmitted to the output gear 5. The output speed of the output gear 5 is the speed after two reductions, which can better control the output speed. In addition, the output gear 5 is set above the drive gear 2, which makes the overall motor occupy a smaller area and has a compact structure, making it suitable for small and exquisite gifts.

[0026] In this embodiment, the present invention also includes a housing, which covers the drive motor 1 and the drive gear 2 and the reduction assembly, thus providing a sealing function. The housing is also waterproof, making the motor suitable for gifts containing water.

[0027] In this embodiment, the housing includes a lower shell 6 and an upper cover 7. The lower shell 6 has a receiving cavity, and the upper cover 7 covers the top of the lower shell 6. The upper cover 7 is bolted to the lower shell 6, which provides a stable connection and facilitates disassembly and assembly.

[0028] In this embodiment, the bottom center of the lower housing 6 is provided with a through hole 8 for the drive tooth 2 to pass through and a support frame 9 for the output tooth 5 to be placed thereon. The support frame 9 is located above the through hole 8, and the top surface of the support frame 9 is provided with a strip groove 10. The strip groove 10 is used for the central shaft of the output tooth 5 to be inserted therein, and the center of the strip groove 10 corresponds to the circle of the through hole 8. The drive tooth 2 of the drive motor 1 is inserted into the lower housing 6 through the through hole 8. The drive tooth 2 meshes with the first reduction gear 3 in the lower housing 6. The output tooth 5 is placed on the support frame 9, and the central shaft of the output shaft is inserted into the strip groove 10. The strip groove 10 does not lock the central shaft of the output shaft, and the output shaft can rotate under the transmission of the second reduction gear 4. The support frame 9 plays the role of supporting the output shaft and placing the output shaft above the drive shaft, so that the output shaft and the drive shaft are aligned on the same axis.

[0029] In this embodiment, the bottom of the lower shell 6 is also provided with two slots 11. The two slots 11 are respectively used for the central shaft of the first reduction gear 3 and the central shaft of the second reduction gear 4 to pass through. The slots 11 do not lock the central shaft of the first reduction gear 3 and the central shaft of the second reduction gear 4. The first reduction gear 3 can rotate under the transmission of the drive gear 2, and the second reduction gear 4 can rotate under the transmission of the first reduction gear 3. The two slots 11 serve to accommodate the first reduction gear 3 and the second reduction gear 4.

[0030] In this embodiment, the output gear 5 includes a gear portion 12 and an output portion 13, which are integral structures. The gear portion 12 is used to mesh with the second reduction gear 4, and the output portion 13 is used to connect to an external structure.

[0031] In this embodiment, the top end of the output part 13 protrudes from the top of the housing, and the top end of the output part 13 is provided with a positioning notch 14, which is used to position the output part 13 when it is inserted into an external structure.

[0032] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
