Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a speed reduction clutch motor. Background Art

[0002] A clutch motor is a motor that can be switched between electric and manual operation, wherein the clutch motor includes a clutch and a drive motor. Most of the clutch motors are controlled by the driving gear of the drive motor to rotate, thereby completing the clutch operation. However, the existing clutch motor directly drives the driven gear of the clutch to rotate through the driving gear, so that they are always in a meshing rotation state. During long-term use, the clutch will cause wear, resulting in failure to form a meshing connection in time during subsequent use, resulting in errors during operation.

[0003] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0004] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a reduction clutch motor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a preferred solution, the upper end of the driving clutch block is provided with an upper transmission convex tooth protruding upward, and the lower end of the driven wheel is provided with a lower transmission convex tooth protruding downward. The driving clutch block is lifted upward by a stop pin, so that the upper transmission convex tooth and the lower transmission convex tooth of the driven wheel abut against each other, thereby driving the driven wheel to rotate.

[0008] As a preferred solution, the number of the upper transmission cams and the lower transmission cams is the same, and at least two are provided, and at least two upper transmission cams and lower transmission cam arrays are distributed on the upper end surface of the driving clutch block and the lower end surface of the driven wheel.

[0009] As a preferred solution, the number of the stop grooves is set to at least two, and the at least two stop groove arrays are distributed at the lower end of the driving clutch block. The structure of the stop groove is set so that the center height is higher than the height on the left and right sides and is crest-shaped. The stop pin rotates with the output shaft and moves in the stop groove, thereby causing the driving clutch block to rise and lift up / lower away.

[0010] As a preferred solution, a return spring is further provided between the driving clutch block and the driven wheel, and the return spring is sleeved on the output shaft. The stop pin rotates close to the inner end of the stop groove to lift the driving clutch block upward, so that the return spring is compressed upward to generate elastic potential energy, causing the driven wheel to start rotating; the stop pin is away from the inner end of the stop groove, and the driving clutch block is subjected to the elastic restoring force of the return spring, thereby popping the driving clutch block downward, so that the driving clutch block is away from the driven wheel, and the driven wheel stops rotating.

[0012] As a preferred embodiment, the gear set includes a reduction gear and a gear pin. The number of the reduction gears is set to be plural and they are arranged in sequence to form a meshing gear set. The lower end of the output shaft is installed in the reduction gear located above. The gear pin includes a first gear pin and a second gear pin. The first gear pin passes through the center of the reduction gear in sequence and is fixed to the upper shell and the lower shell through the upper and lower ends.

The clutch spring is fixedly installed between the mounting groove and the through hole. The inner end surface of the clutch spring is abutted against and pushed outward by the damping spring, and the outer end surface extends into the through hole and provides resistance to the driving clutch block. When the driving clutch block is lifted upward, the outer end surface of the clutch spring will abut against the outer surface of the driving clutch block and provide limiting resistance to it.

[0014] As a preferred solution, the driven wheel is installed on the upper end of the output shaft through a bolt passing through the center thereof, and the driven wheel can rotate arbitrarily when it is away from the driving clutch block.

[0015] As a preferred solution, the driving motor is a brushed motor.

[0016] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0017] The utility model has a simple structure and is convenient and quick to use. The clutch block in the clutch is set to an active state. When the driving motor is started, the driving clutch block will be lifted up to form a contact connection relationship with the driven wheel, and the driven wheel is pushed to rotate by the driving clutch block to complete the clutch operation; conversely, when the driving motor stops, the driving clutch block will drop away from the driven wheel so that the two will not contact each other, allowing the driven wheel to rotate arbitrarily without causing wear to the driving clutch block, thereby extending the service life and having good stability and transmission effect.

[0030] Reference Figure 1-4 As shown: A reduction clutch motor includes a housing 10, the housing 10 is provided with a driving motor 20, a driving wheel 30, a gear set 40, an output shaft 50, a driving clutch block 60 and a driven wheel 70, the driving wheel 30 is sleeved on the rotating shaft extended from the driving motor 20, the gear set 40 is arranged on one side of the driving wheel 30 and meshes with it, the output shaft 50 is inserted on the gear set 40 and rotates with it, the driving clutch block 60 and the driven wheel 70 are both sleeved on the output shaft 50 At the end, the driving clutch block 60 is located below the driven wheel 70, and a stop pin 51 is further provided on the output shaft 50 and is located below the driving clutch block 60. An inclined stop groove 61 is provided at the lower end of the driving clutch block 60.

[0031] In this embodiment, the upper end of the driving clutch block 60 is provided with an upper transmission convex tooth 62 protruding upward, and the lower end of the driven wheel 70 is provided with a lower transmission convex tooth 71 protruding downward. The driving clutch block 60 is lifted upward by the stop pin 51, so that the upper transmission convex tooth 62 and the lower transmission convex tooth 71 of the driven wheel 70 abut against each other, thereby driving the driven wheel 70 to rotate.

[0032] In this embodiment, the number of the upper transmission teeth 62 and the lower transmission teeth 71 is the same, and at least two are provided. The at least two upper transmission teeth 62 and lower transmission teeth 71 are arrayed and distributed on the upper end surface of the driving clutch block 60 and the lower end surface of the driven wheel 70.

The structure of the stop groove 61 is set so that the center height is higher than the height on the left and right sides and is crest-shaped.

[0035] In this embodiment, the shell 10 includes an upper shell 11 and a lower shell 12. The upper shell 11 is provided with a through hole 13 which passes through from top to bottom and allows the output shaft 50 to pass through. The driving clutch block 60 is mounted on the output shaft 50 and is located at the upper end of the through hole 13. The gear set 40, the driving motor 20 and the driving wheel 30 are all installed between the lower shell 12 and the upper shell 11.

[0036] In this embodiment, the gear set 40 includes a reduction gear 41 and a gear pin 42. The number of the reduction gears 41 is set to be plural and arranged in sequence to form a meshing gear set 40. The lower end of the output shaft 50 is installed in the reduction gear 41 located above. The gear pin 42 includes a first gear pin 42 and a second gear pin 42. The first gear pin 42 passes through the center of the reduction gear 41 in sequence and is fixed to the upper shell 11 and the lower shell 12 through the upper and lower ends. The second gear pin 42 passes through the reduction gear 41 and the output shaft 50 from bottom to top in sequence for fixation, and its lower end is used to be fixed in the lower shell 12.

[0037] In this embodiment, a downwardly recessed mounting groove 14 is provided at the top of the upper shell 11, and the side end of the mounting groove 14 is communicated with the through hole 13. A damping spring 15 and a clutch spring 16 are also provided in the mounting groove 14. The damping spring 15 is placed in the mounting groove 14, and one end of the damping spring 15 extends toward the through hole 13. The clutch spring 16 is fixedly installed between the mounting groove 14 and the through hole 13. The inner end surface of the clutch spring 16 is abutted against and pushed outward by the damping spring 15, and the outer end surface extends into the through hole 13 and provides resistance to the driving clutch block 60; when the driving clutch block 60 is lifted upward, the extended outer end surface of the clutch spring 16 will abut against the outer surface of the driving clutch block 60 and provide limiting resistance to it.

[0038] In this embodiment, the driven wheel 70 is installed on the upper end of the output shaft 50 by means of bolts passing through the center thereof. The driven wheel 70 can rotate arbitrarily when it is away from the driving clutch block 60 .

[0039] In this embodiment, the driving motor 20 is a brushed motor.

[0040] Working principle: by installing the driving wheel 30 on the rotating shaft extended by the driving motor 20, and placing the gear set 40 on one side of the driving wheel 30 and meshing with it, then the lower end of the output shaft 50 is installed on the reduction gear 41 in the gear set 40, and then the output shaft 50 and the reduction gear 41 are fixed together by the gear pin 42, and then the driving clutch block 60, the return spring 80 and the driven wheel 70 are placed on the upper end of the output shaft 50 in sequence, and then the stop pin 51 is inserted into the output shaft 50 and located in the stop groove 61 below the driving clutch block 60, and then the damping spring 15 and the clutch spring 16 are installed on the top surface of the upper shell 11, and they are extended to the direction of the driving clutch block 60, so that the outer surface of the driving clutch block 60 and the outer end surface of the clutch spring 16 form a resistance.

[0041] When the drive motor 20 is started, the driving wheel 30 drives the gear set 40 and the output shaft 50 to rotate, so that the stop pin 51 is displaced and rotated in the stop groove 61 of the driving clutch block 60, and the driving clutch block 60 can move up and down following the wave-shaped stop groove 61. When the stop pin 51 is located at the edge, the driving clutch block 60 is lifted upward, and the return spring 80 is compressed and deformed, so that the driving clutch block 60 is close to the driven wheel 70. Since the driving clutch block 60 and the driven wheel 70 are provided with an upper transmission convex tooth 62 and a lower transmission convex tooth 71 that abut against each other, the driving clutch block 60 drives the driven wheel 70 to rotate together.

[0042] On the contrary, when the driving motor 20 stops, the return spring 80 will push the driving clutch block 60 downward, so that the stop pin 51 returns to the position of the wave crest in the stop groove 61, thereby allowing the driving clutch block 60 to fall downward and away from the driven wheel 70. At this time, the driven wheel 70 can rotate freely and will not drive the gear set 40 and the driving wheel 30 to rotate.

[0043] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
