New description: [New technical field] This creation is an electric push rod, especially a push rod with a helical gear set. [Prior Art] There are many known devices or mechanisms that require a linear reciprocating drive to provide the required power. Such a linear reciprocating drive is commonly known as a hydraulic pump that uses hydraulic power as a power source. And a screw mechanism driven by an electric motor. Hydraulic cylinders that use hydraulic power also require hydraulic lines and control valves to form a complete hydraulic system 'usually applied to equipment or mechanisms that require greater power' and the hydraulic system is more complex and space-consuming, with limited application. The screw mechanism driven by the electric motor is smaller than the hydraulic system and is capable of making finer movements. It is suitable for equipments that do not require large power, and the typical tail is like the electric tail of a small brake. Doors, electric doors, windows and curtains, electric opening and closing exhaust doors, electric window openers, etc. can be used as the power source by using the electric motor to drive the rod mechanism. The conventional fine electric motor drive mechanism, when the fine spur gear planetary I wheel is in operation, will suffer from excessive noise due to interference and friction between the gears. How to reduce the noise of the transmission screw mechanism has become one of the problems that the technical field is trying to overcome. In view of this, the creator, in view of the lack of the above-mentioned prior art, has carefully conceived the present invention through careful experimentation and research, and the spirit of perseverance, and the following is a brief description of the present invention. [New content] In order to improve the operation of the spur gear planetary gear set, t is the electric push rod of the tree gear group. The present invention relates to an electric push rod having a helical gear set, comprising a drive motor 'providing transmission power; a first gear set connected to the drive motor and being a transmission gear set; a gear shaft, and the first The gear set is combined with the second gear set and the positive wire portion of the recording shaft of the Qianlang spur gear tube, and the inner helical gear tube is hybridized with the helical gear portion and the first gear (4), and a telescopic push rod coupled to the second gear set and rotating the first gear set, the gear shaft and the second gear set by the transmission power provided by the drive motor to drive the telescopic push rod. With the above-mentioned concept by the creator, the present invention can greatly reduce noise due to the reduction in operational interference and friction by incorporating the helical gear into the operation of the window wheel group. At the same time, after the listening round of the people, the interference and the shouting of the eyes are small, and the overall efficiency of the transmission will also increase effectively. M438564 [Embodiment] The present invention discloses an electric hybrid rod having a helical gear set, the content of which will be described below by way of a preferred embodiment, and the embodiment is only preferred, and the implementation of the present invention is limited to the In the preferred embodiments, those skilled in the art will be able to devise other embodiments in accordance with the spirit of the embodiments disclosed herein.

Next, please see the second figure, which is an enlarged view of a transmission gear set combined with the push of the helical gear set. As can be seen from the second figure, in addition to the original rod π and the drive motor portion 13, the transmission gear set 12 is driven by the first 121, the second gear set 122, the gear shaft 123, and an inner spur gear. The inner helical gear tube 126 is constructed.

The first wheel set 121 is closely spaced from the driving teeth (4) by the slanting helical gears (2) 1 respectively. The Γ gear set 121 is then moved through the gear shaft 123 to the first gear, and the yoke tube is fixed 1251 and the second gear. In addition, the gear wheel 122 is spliced, and the inner helical gear tube 126 is coupled to: the tooth: the tube 125 is '' and is provided with a helical gear portion 1261, and the helical gear is combined with the helical gear 1 on the first gear set 121 .
