Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a miniature geared motor with a protective structure. Background Technology

[0002] A miniature geared motor consists of a motor and a reducer. The motor generates rotational power when energized, while the reducer uses gear sets and other structures to reduce speed and increase torque according to the transmission ratio. Its applications are numerous: in smart homes, it drives smart door locks and curtain motors; in industry, it powers small automated equipment and 3D printers, providing precise motion control; and in the medical field, it assists in the operation of blood glucose meters and small massagers, meeting diverse needs with its compact size.

[0003] For miniature geared motors with protective structures, the installation of the protective cover and the miniature motor is crucial. When bolting, first precisely drill holes at the corresponding positions on the motor housing and the protective cover, then tighten with matching bolts and nuts to ensure a secure connection. Welding installation requires meticulous operation; protect critical parts of the motor and weld precisely along the joint edges to make the protective cover and motor a single unit.

[0004] In existing technologies, the protective structure of some micro geared motors is usually fixed by bolts and welding, which makes installation and disassembly relatively cumbersome. For example, bolts require tools, and if the bolts are rusted or damaged, it will affect the disassembly and installation of the protective cover, increasing the difficulty of disassembly. Welding fixation makes disassembly even more difficult and cumbersome, which not only makes installation inconvenient but also increases the difficulty of maintenance. Therefore, a micro geared motor with a protective structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a miniature geared motor with a protective structure, aiming to improve the problem that the use of bolts and welding for fixing in the prior art leads to relatively cumbersome installation and disassembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A miniature geared motor with a protective structure includes a rubber base plate. A noise reduction component for reducing noise during motor operation is installed at the bottom of the rubber base plate. Multiple fixed feet are fixedly connected to the top of the rubber base plate. Multiple sliding plates are fixedly connected to the inner walls of the fixed feet. A mounting rod is slidably connected to the outer wall of each sliding plate. A rotating rod is fixedly connected to the inner wall of the mounting rod. A locking whistle is rotatably connected to the outer wall of the rotating rod. A mounting foot is slidably connected to the bottom of the locking whistle. Multiple wedge-shaped blocks are fixedly connected to the bottom of the mounting rod. Multiple limiting grooves are formed on the inner walls of the wedge-shaped blocks. A protective shell is fixedly connected to the outer wall of the mounting foot.

[0008] As a further description of the above technical solution:

[0009] The noise reduction component includes a rubber damping pad, which is in contact with the surface of the rubber base plate. An installation plate is fixedly connected to the outer wall of the rubber base plate, and a noise reduction sponge is fixedly connected to the inner wall of the installation plate. A porous sound-absorbing plate is fixedly connected to the inner wall of the rubber base plate.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the rubber shock-absorbing pad is threaded with a fixing screw, and the bottom outer wall of the fixing screw is threaded with a rubber support foot.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the fixing screw is threadedly connected to the inner wall of the porous sound-absorbing plate, and the outer wall of the fixing screw is threadedly connected to the inner wall of the rubber base plate.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the rubber support foot is in contact with the inner wall of the noise-reducing sponge, and the bottom of the rubber support foot is fixedly connected to the inner wall of the mounting plate.

[0016] As a further description of the above technical solution:

[0017] The bottoms of the plurality of wedges are in contact with the bottoms of the plurality of sliding plates, and the bottom of the mounting foot is in contact with the top of the fixing foot;

[0018] As a further description of the above technical solution:

[0019] The outer wall of the protective shell has multiple heat dissipation holes, and the inner wall of the protective shell is detachably connected to a micro motor.

[0020] As a further description of the above technical solution:

[0021] The micro motor has a drive end inside, the bottom of the rubber shock-absorbing pad is in contact with the bottom of the micro motor, and the outer wall of the fixing screw is threaded to the inner wall of the micro motor.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the mounting rod is inserted into the interior of the fixed foot and the mounting foot, and the slot between the bottom wedge block is aligned with the sliding plate. When the wedge block slides to the bottom, the locking whistle is rotated. The rotation of the locking whistle causes the mounting rod and the wedge block at the bottom to rotate. At this time, the limiting groove no longer corresponds with the sliding plate. The locking whistle is moved, and the change in the position of the locking whistle causes the mounting rod to rise. At this time, the wedge block will contact the bottom of the sliding plate. The mounting foot and the fixed foot are fixed together by the pressure between the two, which facilitates the installation and fixation between the protective shell and the rubber base plate. This structure greatly facilitates the disassembly of the protective shell, and facilitates quick installation and disassembly. While facilitating quick installation, the convenient disassembly also helps in the maintenance of the motor.

[0024] 2. In this utility model, the rubber shock-absorbing pad absorbs part of the vibration of the micro motor and then transmits the remaining vibration to the rubber base plate. At this time, the porous sound-absorbing plate absorbs the noise generated by the vibration to reduce the transmission of the noise generated by the vibration to the outside world. The rubber support foot at the bottom of the fixing screw further reduces the vibration transmitted when the micro motor is running, and the noise-reducing sponge can effectively prevent the noise from being transmitted to the outside world and affecting the outside world.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 2 to 4 This utility model provides an embodiment of a miniature geared motor with a protective structure, including a rubber base plate 1. The bottom of the rubber base plate 1 is provided with a noise reduction component for reducing noise during motor operation. The noise reduction component can effectively reduce the noise generated by the miniature motor 18 during operation. Multiple fixing feet 17 are fixedly connected to the top of the rubber base plate 1. Multiple sliding plates 9 are fixedly connected to the inner wall of the fixing feet 17. The sliding plates 9 are used to cooperate with the mounting rod 8 and the wedge block 10 to achieve a fixed connection between the protective shell 2 and the rubber base plate 1. The mounting rod 8 is inserted into the fixing feet 17 and the mounting feet 19, so that the slot of the wedge block 10 is aligned with the sliding plate 9 and inserted. The rotation of the locking whistle 5 drives the mounting rod 8 and the wedge block 10 to rotate, changing the correspondence between the limiting groove 7 and the sliding plate 9, so that the wedge block 10 contacts the bottom of the sliding plate 9 to generate pressure and achieve fixation.

[0033] A mounting rod 8 is slidably connected to the outer wall of the sliding plate 9. A rotating rod 6 is fixedly connected to the inner wall of the mounting rod 8. The rotating rod 6 is used to drive the locking whistle 5 to rotate, thereby rotating the mounting rod 8 and the wedge block 10, and adjusting the position of the limiting groove 7. The locking whistle 5 is rotatably connected to the outer wall of the rotating rod 6. The locking whistle 5 drives the mounting rod 8 to rise through rotation and position change, so that the wedge block 10 contacts and is fixed to the bottom of the sliding plate 9. A mounting foot 19 is slidably connected to the bottom of the locking whistle 5. Multiple wedge blocks 10 are fixedly connected to the bottom of the mounting rod 8. The wedge blocks 10 generate pressure by contacting the bottom of the sliding plate 9, so as to fix the mounting foot 19 and the fixed foot 17. Multiple limiting grooves 7 are opened on the inner wall of the wedge block 10. The limiting grooves 7 change according to the correspondence with the sliding plate 9 to help fix the mounting foot 19 and the fixed foot 17.

[0034] A protective shell 2 is fixedly connected to the outer wall of the mounting foot 19. The bottoms of multiple wedge blocks 10 are in contact with the bottoms of multiple sliding plates 9. The bottom of the mounting foot 19 is in contact with the top of the fixed foot 17. The protective shell 2 is used to cover the micro motor 18 for protection. Multiple heat dissipation holes 3 are provided on the outer wall of the protective shell 2 for heat dissipation of the micro motor 18 to ensure normal operation of the motor. The micro motor 18 is detachably connected to the inner wall of the protective shell 2. The detachable connection facilitates the subsequent inspection and maintenance of the micro motor 18. The micro motor 18 is provided with a drive end 4 inside. The drive end 4 is used to connect with the components that need to be driven. The bottom of the rubber shock-absorbing pad 16 is in contact with the bottom of the micro motor 18. The outer wall of the fixing screw 11 is threadedly connected to the inner wall of the micro motor 18 for easy motor installation.

[0035] Reference Figures 1 to 3 The noise reduction component includes a rubber damping pad 16, which is in contact with the surface of the rubber base plate 1. The rubber damping pad 16 is used to absorb some of the vibration generated by the micro motor 18 and reduce the vibration transmitted to the rubber base plate 1. A mounting plate 15 is fixedly connected to the outer wall of the rubber base plate 1. The mounting plate 15 is used to fix the noise reduction sponge 13. The noise reduction sponge 13 is fixedly connected to the inner wall of the mounting plate 15. The noise reduction sponge 13 is used to prevent noise from being transmitted to the outside and reduce the impact on the outside. A porous sound-absorbing plate 14 is fixedly connected to the inner wall of the rubber base plate 1. The porous sound-absorbing plate 14 is used to absorb the noise generated by the vibration of the micro motor 18 and reduce the external transmission of noise.

[0036] The inner wall of the rubber damping pad 16 is threaded with a fixing screw 11. The fixing screw 11 is used to fix the rubber damping pad 16, rubber support 12 and other components. The bottom of the fixing screw 11 is fixedly connected to the rubber support 12. The rubber support 12 is used to further reduce the vibration transmitted when the micro motor 18 is operating. The outer wall of the fixing screw 11 is threadedly connected to the inner wall of the porous sound-absorbing plate 14. The outer wall of the fixing screw 11 is threadedly connected to the inner wall of the rubber base plate 1. The outer wall of the rubber support 12 is in contact with the inner wall of the noise-reducing sponge 13. The bottom of the rubber support 12 is fixedly connected to the inner wall of the mounting plate 15 to facilitate the reduction of vibration transmitted when the motor is operating.

[0037] Working principle: When protection of the micro motor 18 is required, first, the protective housing 2 is placed over the micro motor 18. Then, the mounting feet 19 on the outer wall of the protective housing 2 are placed on the surface of the fixing feet 17. At this time, the mounting rod 8 is inserted into the interior of the fixing feet 17 and the mounting feet 19. It should be noted that the slot between the bottom wedge blocks 10 is aligned with the sliding plate 9 and inserted. When the wedge blocks 10 slide to the bottom, the limiting groove 7 will disengage from the sliding plate 9. Rotating the locking whistle 5 will cause the bottom mounting rod 8 and the wedge blocks 10 to rotate. When the limiting groove 7 no longer corresponds to the sliding plate 9, and then when the locking whistle 5 contacts the mounting foot 19, the locking whistle 5 is placed horizontally. When the locking whistle 5 is moved, the locking whistle 5 changes from horizontal to vertical. The change in the position of the locking whistle 5 will cause the mounting rod 8 to rise. Due to the previous rotation, the limiting groove 7 no longer corresponds to the sliding plate 9. At this time, the wedge block 10 will contact the bottom of the sliding plate 9. In this way, the mounting foot 19 and the fixing foot 17 are fixedly connected together by the pressure between the two, so as to facilitate the installation and fixation between the protective shell 2 and the rubber base plate 1.

[0038] When the micro motor 18 operates, noise is inevitable. At this time, the rubber damping pad 16 will absorb some of the vibration of the micro motor 18 and transmit the remaining vibration to the rubber base plate 1. The porous sound-absorbing plate 14 will absorb the noise generated by the vibration to reduce the transmission of the noise generated by the vibration to the outside world. The rubber support foot 12 at the bottom of the fixing screw 11 will further reduce the vibration transmitted when the micro motor 18 is operating. The noise-reducing sponge 13 can effectively prevent the noise from being transmitted to the outside world and affecting the outside world.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
