In a preferred embodiment of the present invention, the first driving gear is smaller than the second driven gear in size.
In a preferred embodiment of the present invention, the first driving gear and the second driven gear are spur gears.
In a preferred embodiment of the present invention, the turbine is made of nylon or polyoxymethylene.
In a preferred embodiment of the present invention, two inner frames of the housing are symmetrically provided with copper sleeves, and two ends of the worm are sleeved in the copper sleeves and are rotatably connected with the copper sleeves through steel balls.
In a preferred embodiment of the utility model, the motor is a 24V motor.
The utility model has the beneficial effects that: the utility model discloses a drive assembly of rear-view mirror wiper utilizes first initiative tooth and second driven gear to carry out once reducing speed, utilizes worm, turbine structure to carry out the secondary speed reduction, and although the motor is little but torque output power is very big, can reach the torsion of big motor, and the structure is small and exquisite, compact, and the dead weight is light, and little motor is with low costs, has saved installation space, has simplified installation steps greatly.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:
fig. 1 is a schematic view of the internal structure of a driving assembly of a rearview mirror wiper blade according to the present invention;
fig. 2 is a schematic structural view of a driving assembly of a rearview mirror wiper blade of the present invention;
fig. 3 is an external view of a driving assembly of a rearview mirror wiper blade according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, a driving assembly of a rearview mirror wiper of the present invention includes: the worm gear mechanism comprises a shell 1, a motor 2, a worm 3, a turbine 4, a connecting rod 5 and a swing arm 6, wherein the motor 2, the worm 3, the turbine 4, the connecting rod 5 and the swing arm 6 are arranged in the shell, a first driving gear 7 is sleeved on an output shaft of the motor, a second driven gear 8 meshed with the first driving gear is arranged at the lower end of the worm, a spiral tooth part 9 in the middle of the worm is meshed with the turbine, one end of the connecting rod is movably hinged to the non-central position of the turbine, the other end of the connecting rod is hinged to one end of the swing arm, a rotating shaft 10 is connected to the other end of the swing arm and penetrates through the other end of the swing arm, power of the motor is transmitted to the second driven gear through the first driving gear, the second driven gear drives the worm to rotate in a copper sleeve, and the spiral tooth part in the middle of the worm is meshed with the turbine to drive the swing action of a rotating arm through the connecting rod.
Specifically, the size of first driving gear is less than second driven gear, first driving tooth and second driven gear are straight-tooth gear, the turbine is the nylon material, utilizes first driving tooth and second driven gear to carry out once speed reduction, utilizes worm, turbine structure to carry out the secondary speed reduction, simple structure, small in size is provided with the piece that resets at the back of turbine, and the piece subassembly that resets is prior art, and the piece subassembly that resets rotates under windscreen wiper drive gear's drive, can cooperate with the piece subassembly that resets in order to realize the effect that stops behind a stroke of windscreen wiper back and forth swing.
