[0002] The motor is mainly composed of a stator and a rotor. The direction of the force on the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field). The working principle of the motor is that the magnetic field acts on the force on the current, causing the motor to rotate.

[0003] However, the conventional device still has the following problems when used:

[0004] The motor will vibrate when working, thus generating noise. At present, most motors usually have a base on the motor housing, and the base is directly connected to the shock-absorbing structure, which can play a role in shock absorption;

[0005] However, during the shock absorption process, the components inside the shock absorption structure will collide with each other, thus generating a lot of noise. The long-term collision between the components will shorten the service life of the shock absorption structure.

[0006] Therefore, we need a vibration reduction and noise reduction device for motors to solve the problem that the service life of the shock-absorbing structure is short and to increase the service life of the shock-absorbing structure. Utility Model Content

[0028] Embodiment 1

[0029] See also Figures 1 to 7 The utility model provides a technical solution: it includes a box body 1, a controller 2 is fixedly connected to one side of the box body 1, a shock absorber 3 is fixedly connected to the middle position inside the box body 1, a shock absorber 2 4 is slidably connected inside the shock absorber 3, a lubricant sensor 7 is fixedly connected to the inner wall of the shock absorber 3, a bottom plate 42 is fixedly connected to the bottom of the shock absorber 2 4, a limiting ring 410 is fixedly connected to the middle position inside the bottom plate 42, a baffle 46 is fixedly connected to the inside of the shock absorber 2 4, an outflow hole 47 is opened on the top of the baffle 46, a placement plate 5 is movably connected to the top of the box body 1, and a through hole 411 is opened above the bottom of the shock absorber 2 4 near the bottom plate 42.

[0030] The lubricant sensor 7 is used to detect the lubricant inside the shock absorber 3. When the lubricant inside the shock absorber 3 becomes less, the lubricant sensor 7 will transmit the sensing result to the controller 2. When the controller 2 receives the information transmitted by the lubricant sensor 7, the controller 2 can control the electric telescopic rod 45 to move. Then, through the movement of the electric telescopic rod 45, the plug 44 can be driven to leave the bottom of the outflow hole 47, so that the bottom of the outflow hole 47 is not blocked, thereby facilitating the outflow of the lubricant inside the shock absorber 4, avoiding the lubricant from flowing out of the outflow hole 47 when there is no need to add lubricant to the inside of the shock absorber 3, thereby reducing the waste of lubricant accordingly.

[0031] Embodiment 2

[0032] The internal movable connection of the shock absorber 24 is provided with a pushing structure, which includes a push rod 41. The bottom of the push rod 41 is fixedly connected to the middle position at the lower part of the shock absorber 3. The outer wall of the push rod 41 is slidably connected to the inside of the limit ring 410. A moving plate 43 is slidably connected to the lower part of the outer wall of the push rod 41. A plug 44 is fixedly connected to the top of the moving plate 43. An electric telescopic rod 45 is fixedly connected to the side of the top of the moving plate 43 close to the plug 44. The output end of the electric telescopic rod 45 is fixedly connected to the bottom of the baffle 46. The outer wall of the plug 44 overlaps the bottom of the outflow hole 47. The outer wall of the push rod 41 is simultaneously connected to the center of the inside of the moving plate 43 and the baffle 46. The outer wall of the push rod 41 is simultaneously slidably connected to the center of the inside of the moving plate 43 and the baffle 46. A moving plate 2 48 is fixedly connected to the top of the push rod 41. A plug 2 49 is fixedly connected to the bottom of the moving plate 48. The outer wall of the plug 2 49 is slidably connected to the inside of the outflow hole 47.

[0033] When the lubricant inside the shock absorber 24 enters the bottom of the shock absorber 24 through the outflow hole 47, it will enter the inner wall of the shock absorber 13 through the through hole 411. After the lubricant enters the inner wall of the shock absorber 13, a protective film on one side of the inner wall of the shock absorber 13 is formed, thereby avoiding friction and wear between the shock absorber 13 and the shock absorber 24 during movement, and correspondingly increasing the service life of the shock absorber 13 and the shock absorber 24.

[0034] Embodiment 3

[0035] The top of the movable plate 2 48 is fixedly connected with a stirring structure, the stirring structure includes a main shaft 6 , the outer wall of the main shaft 6 is fixedly connected with a stirring blade 61 , and the outer wall of the stirring blade 61 is slidably connected to the inside of the shock absorber 2 4 .

[0036] The movement of the movable plate 2 48 can drive the main shaft 6 to move, and the movement of the main shaft 6 can drive the stirring blade 61 to move up and down in the lubricant inside the shock absorber 2 4. The up and down movement of the stirring blade 61 in the lubricant can disperse the lubricant into smaller droplets, thereby improving the fluidity of the lubricant, avoiding the lubricant from flowing out too slowly, increasing the time for adding the lubricant, and correspondingly improving the efficiency of the lubricant outflow and saving the time for adding the lubricant.

[0037] The working principle and use process of the utility model are as follows: when working, first, the lubricant in the shock absorber 3 is detected by the lubricant sensor 7. When the lubricant in the shock absorber 3 becomes less, the lubricant sensor 7 will transmit the sensed result to the controller 2. When the controller 2 receives the information transmitted by the lubricant sensor 7, the electric telescopic rod 45 can be controlled by the controller 2 to move. Then, through the movement of the electric telescopic rod 45, the plug 44 can be driven to leave the bottom of the outflow hole 47, so that the bottom of the outflow hole 47 is not blocked, thereby facilitating the outflow of the lubricant in the shock absorber 4, avoiding the lubricant from flowing out of the outflow hole 47 when there is no need to add lubricant to the inside of the shock absorber 3, and correspondingly reducing the waste of lubricant.

[0038] It should be noted that without adding lubricant, the cooperation of plug 1 44 and plug 2 49 can more effectively seal the lubricant inside the shock absorber 2 4, thereby preventing the lubricant from flowing out when it is not used, and correspondingly saving the waste of lubricant.

[0039] At this time, the vibration generated by the movement of the motor can transmit the vibration force to the shock absorber 1 3 and the shock absorber 2 4 through the placement plate 5. When the shock absorber 1 3 and the shock absorber 2 4 are forced to move up and down, the shock absorber 1 3 can drive the push rod 41 to move upward inside the limit ring 410 when moving upward, and then the push rod 41 can drive the moving plate 2 48 to move, and then the movement of the moving plate 2 48 can drive the plug 2 49 to slide out from the inside of the outflow hole 47. Out, so that there is no obstruction at the outflow hole 47. At this time, the lubricant inside the shock absorber 24 will enter the bottom of the shock absorber 24 through the outflow hole 47, and finally enter the inner wall of the shock absorber 1 3 through the through hole 411. After the lubricant enters the inner wall of the shock absorber 1 3, a protective film on one side of the inner wall of the shock absorber 1 3 can be formed, thereby avoiding friction and wear between the shock absorber 1 3 and the shock absorber 2 4 during movement, and correspondingly increasing the service life of the shock absorber 1 3 and the shock absorber 2 4.

[0040] When the lubricant inside the shock absorber 24 enters the bottom of the shock absorber 24 through the outflow hole 47, it will enter the inner wall of the shock absorber 13 through the through hole 411. After the lubricant enters the inner wall of the shock absorber 13, a protective film on one side of the inner wall of the shock absorber 13 is formed, thereby avoiding friction and wear between the shock absorber 13 and the shock absorber 24 during movement, and correspondingly increasing the service life of the shock absorber 13 and the shock absorber 24.

[0041] The movement of the movable plate 248 can drive the main shaft 6 to move, and the movement of the main shaft 6 can drive the stirring blade 61 to move up and down in the lubricant inside the shock absorber 24. The up and down movement of the stirring blade 61 in the lubricant can disperse the lubricant into smaller droplets, thereby improving the fluidity of the lubricant, avoiding the lubricant from flowing out too slowly, increasing the time for adding the lubricant, and correspondingly improving the efficiency of the lubricant outflow and saving the time for adding the lubricant.

[0042] When the lubricant is added, the lubricant sensor 7 is used to detect the lubricant inside the shock absorber 3. When the lubricant inside the shock absorber 3 is normal, the lubricant sensor 7 will transmit the sensing result to the controller 2. When the controller 2 receives the information transmitted by the lubricant sensor 7, the electric telescopic rod 45 can be controlled by the controller 2 to move, and the movement of the electric telescopic rod 45 drives the plug 44 to return to its original position, so that the plug 44 is blocked at the bottom of the outflow hole 47 again, which prevents the lubricant from flowing out of the outflow hole 47 when the push rod 41 drives the plug 2 49 to move, thereby correspondingly increasing the blocking effect of the outflow hole 47.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
