The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the terms are used in the description to indicate that the referenced device or element must have the specified orientation, be constructed and operated in the specified orientation, and not for the purposes of limitation.

With reference to fig. 1 to 3, a window motor according to the present invention will be described in detail below. Specifically, the window motor can be mounted to a vehicle so as to be able to drive a window of the vehicle up and down.

Specifically, the window motor includes a motor assembly 10, a worm 20, a turbine assembly 30, and at least two buffers 40. The worm 20 is drivingly connected to the motor assembly 10 such that the worm 20 is driven to rotate.

More specifically, the motor assembly 10 is implemented to include a motor and an electrically conductive assembly electrically connected to the motor. The turbine assembly 30 includes a mounting housing 31, a drive turbine 32, and a driven turbine 33. The worm 20 and the worm gear 32 are respectively mounted to the mounting housing 31 such that the gear teeth 3201 of the worm gear 32 are engaged with the helical teeth 21 of the worm 20, and the worm gear 32 is driven by the worm 32 when the worm 20 is driven to rotate by the motor assembly 10.

The mounting housing 31 includes a housing body 311 and a cover 312. The housing body 311 defines a worm chamber 31101, a worm wheel chamber 31102, and a side opening 31103 communicating with the worm chamber 31101 and the worm wheel chamber 31102. The drive turbine 32 is disposed in the turbine housing 31102. One end of the worm 20 is implemented as an output shaft of the motor in the motor assembly 10, wherein the other end of the worm 20 is inserted into the worm cavity 31101, and when the worm 20 is inserted into the worm cavity 31101, the spiral teeth 21 on the worm 20 are engaged with the gear teeth 3201 of the driving turbine 32 disposed in the turbine cavity 31102 through the side opening 31103.

The transmission worm gear 32 includes a worm gear main body 321, an intermediate rod 322, and at least two connecting ribs 323 connecting the worm gear main body 321 and the intermediate rod 322. The gear teeth 3201 are disposed on an outer sidewall of the turbine body 321. A buffer groove 320 is formed between two adjacent connecting ribs 323, the intermediate rod 322 and the inner side wall of the turbine main body 321 for accommodating one buffer member 40.

The driven worm wheel 33 is sleeved on the intermediate rod 322 of the driving worm wheel 32, so that the driven worm wheel 33 on the intermediate rod 322 can be driven to rotate when the worm wheel main body 321 is driven by the worm 20. It can be understood that, through the passive turbine 33, the power output by the motor assembly 10 can be further transmitted to the passive turbine 33, so that when the window motor is mounted on the vehicle, the power is further transmitted to the window of the vehicle through the passive turbine 33.

The cover 312 is covered on the housing main body 311 to cover the turbine chamber 31102 and the buffer tank 320. Preferably, the cover 312 is detachably mounted to the housing body 311, so that the buffer member 40 mounted in the buffer groove 320 can be replaced after being severely worn. The cover 312 forms a middle window 3120 to allow the passive turbine 33 to pass through after the cover 312 is covered on the turbine chamber 31102 and the buffer groove 320.

It is worth mentioning that, in the present invention, each of the cushion members 40 includes an inner side surface 401 and an outer side surface 402. When the cushion member 40 is disposed in the cushion groove 320, the inner surface 401 of the cushion member 40 is closely attached to the intermediate rod 322 of the power turbine 32. The outer side surface 402 of the damper 40 is in close contact with the inner side wall of the turbine body 321.

The passive turbine 33 has an upper side 3301, a lower side 3302, and a bore 3303. The driven worm gear 33 is provided with driven gear teeth 331, wherein the driven gear teeth 331 protrude from the upper side 3301 to the upper side 3301. When the driven turbine 33 is mounted on the middle rod 322 of the driving turbine 32, the middle rod 322 can pass through the sleeve hole 3303. The passive gear teeth 331 of the passive turbine 33 can pass through the intermediate window 3120 formed by the cover 312.

When the driven worm wheel 33 is sleeved on the middle rod 322 of the driving worm wheel 32, the buffer member 40 is held between the driven worm wheel 33 and the lower side surface 3302 of the driving worm wheel 32 to reduce the contact area between the driven worm wheel 33 and the driving worm wheel 32, so that when the driving worm wheel 32 is driven to rotate by the worm 20, the driven worm wheel 33 does not directly collide with the worm wheel main body 322 of the driving worm wheel 32, and the noise generated by the window motor is reduced.

Further, the outer side surface 402 of the buffer 40 is provided with a notch 41. The lower side 3302 of the passive turbine 33 is provided with at least two prongs 332. After the driven worm gear 33 is sleeved on the middle rod 322 of the driving worm gear 32, the two pins 332 of the driven worm gear 33 can be inserted into the notches 41 of the buffer members 40.

It should be noted that when the driving worm wheel 32 is driven by the worm 20 to rotate, the buffer member 40 disposed in the buffer slot 320 of the driving worm wheel 32 can push the pin 332 of the driven worm wheel 33, so that the driven worm wheel 33 can be driven by the driving worm wheel 32.

Furthermore, as can be understood by those skilled in the art, since the buffer member 40 is disposed between the driving turbine 32 and the lower side 3302 of the driven turbine 33, and the pins 333 of the driven turbine 33 are covered by the notches 41 formed by the buffer member 40, the space between the driving turbine 32 and the driven turbine 33 is buffered by the buffer member 40, and thus the damage caused by friction between the driving turbine 32 and the driven turbine 33 can be avoided.

In addition, when the window motor is mounted in the vehicle, the bumper 40 located in one of the buffer grooves 320 is worn more than the bumpers 40 of the other buffer grooves 320 after the window motor is operated for a long time. In the present invention, since the plurality of buffering members 40 are disposed behind the buffer groove 320 and are independent of each other between the buffering members 40, when one of the buffering members 40 is worn seriously, only one of the buffering members 40 needs to be replaced, and it is not necessary to replace all the buffering members 40.

It is worth mentioning that in the present invention, the buffer member 40 is implemented to be made of a rubber material. Preferably, in the present invention, the buffer members 40 are implemented in three. That is, in the present invention, the driving turbine 32 forms three buffer grooves 320. Correspondingly, the lower side 3302 of the passive turbine 33 is provided with three pins 332. In addition, since each of the buffers 40 can be provided to have the same shape, the opening of the buffers 40 is facilitated.

It is more worth mentioning that, in the present invention, the buffer member 40 forms a protrusion 42 from the outer side surface 402 to the inner side surface 401 at a portion corresponding to the notch 41, so that the buffer member 40 can be prevented from being broken at a portion corresponding to the notch 41 by increasing the thickness formed by the buffer member 40 from the outer side surface 402 to the inner side surface 401 at a portion corresponding to the notch 41.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
