Embodiment 1

[0034] see Figure 1 ~ Figure 4 , figure 1 It is a schematic diagram of a window opening machine to which the clutch structure of the present invention is applied. The drive mechanism 200 with the clutch structure of the present invention is arranged inside the window opening machine 100 .

[0035] The driving mechanism 200 includes a motor 201 , a gear box 202 and a clutch structure 1 . The motor 201 has an output part 2011 , and the output part 2011 is connected with the gear box 202 through the clutch structure 1 . The gear box 202 includes a first shell part 2021 , a second shell part 2022 , and a transmission gear 2023 located between the first shell part 2021 and the second shell part 2022 . Meanwhile, the first shell part 2021 and the second shell part 2022 also serve as the shell of the clutch structure 1 .

[0036] The clutch structure 1 for the window opener also includes a fixed block 11 arranged between the two casings of the gear box 202 and fixed to the casing...

Embodiment 2

[0048] see Figure 5 ~ Figure 7 , in this embodiment, the difference from the first embodiment above is that there is no need to drive the first gear 141 to move relative to the gear shaft 13 through the slider 12, but the gear shaft 13 passes through the casing of the gear box 202 and extends The way to the outside of the window opening machine casing, and the gear shaft 13 can move linearly along the axial direction of the gear shaft 13 relative to the casing of the gear box 202, so that the gear shaft 13 can move relative to the first gear 141 to achieve clutching. The end of the gear shaft 13 located outside the window opener is provided with an operating part 131, so that the gear shaft 13 can move linearly by pushing and pulling the operating part 131 outside the window opener.

[0049] In this embodiment, the first gear 141 and the teeth 132 are not meshed with each other. The end portion of the gear shaft 13 passes through the first housing part 2021 of the gear box 2...

Embodiment 3

[0055] see Figure 8 ~ Figure 10 , in this embodiment, the difference from the second embodiment above is that the engagement between the engagement portion 16 and the engagement groove 1412 is replaced by the engagement between the first gear 141 and the second gear 142 .

[0056] The first clutch member is at least two first clamping blocks 1413 protruding from the side of the first gear 141 facing the second gear 142. There is an interval between the two first clamping blocks 1413 to form an engaging portion 1414. The second The clutch is a second clamping block 1421 protruding from the side of the second gear 142 facing the first gear 141. The second clamping block 1421 is used to snap into the engaging portion 1414, so that the first gear 141 can drive the second gear 141. The second gear 142 rotates. In this embodiment, the first block 1413 has two arc-shaped pieces, and the second block 1421 also has two arc-shaped blocks. The second block 1421 is snapped into the enga...

Abstract

The invention discloses a clutch structure used for a window opener. The clutch structure is characterized by comprising a first housing part and a second housing part, a gear shaft, a first gear, a second gear and an elastic part, wherein the first housing part and the second housing part are oppositely arranged; the two ends of the gear shaft are rotatably connected with the first housing part and the second housing part separately; the first gear serves as the input part of the clutch structure and is arranged on the gear shaft in a sliding manner; the second gear serves as the output partof the clutch structure and is arranged on the gear shaft in a linkage manner; a first clutch part is arranged on the first gear; a second clutch part is arranged on the gear shaft; the first gear andthe gear shaft can perform relative movement in the axial direction of the gear shaft, so as to enable the first clutch part to be combined with or separated from the second clutch part; and the elastic part acts on the first gear and the second gear to enable the first clutch part and the second clutch part to be kept in a combined state, so as to maintain a trend of synchronous rotation.

Description

technical field [0001] The invention relates to a drive mechanism, especially a clutch structure for motor drive. Background technique [0002] Drivers currently used for electric door and window assemblies, such as a driver for grid shutter assemblies with patent application number CN201410216947.6, include a motor with a rotating shaft, an output member, and a gear set. The gear set has a The speed ratio changes according to the action angle of the output member, so that the output torque of the driver can be matched with the demand of the driver. [0003] The above-mentioned driver is the main way to drive doors and windows at present, but there are still some defects: when the motor is powered off, because the output part of the motor is directly connected to the doors and windows, it cannot be replaced by manual, so that the user cannot manually operate the doors and windows to open and close Doors and windows, this will obviously cause inconvenience to people's normal...
