Description

Technical Field

[0001] This utility model relates to the field of window opening equipment technology, and in particular to a manual and electric integrated window opener. Background Art

[0002] Machines used to open and close windows are called "window openers" or "window openers," and are now a new technology product in the construction industry. Window openers are mainly used for windows that are installed high or far away and cannot be reached by hand; or for windows that are too heavy to open or close with effort.

[0003] In existing technologies, window openers typically include both automatic and manual opening / closing types, and usually also include a clutch device for switching between automatic and manual opening / closing. For example, the electric-manual integrated window opener disclosed in Chinese utility model CN220769208U, when manual control of the output shaft is required, rotating the nut deforms the elastic element, engaging the connecting sawtooth block and the handle sawtooth block, thereby driving the handle to rotate and causing the output shaft to rotate.

[0004] During the actual research and development process, the inventors found that this type of clutch device requires turning the nut to switch between automatic and manual opening and closing, which is a rather cumbersome operation. Moreover, if the user does not turn the nut properly, the connecting sawtooth block and the handle sawtooth block may not be fully engaged, resulting in tooth breakage. The reliability of use needs to be further improved.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a hand-flash integrated window opener, which effectively solves the technical defects of the existing hand-flash integrated window opener, such as cumbersome switching and unreliable switching when switching between manual and automatic opening and closing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a hand-flash integrated window opener, comprising a first output tooth, a second output tooth meshing with the first output tooth, a drive motor for driving the rotation of the first output tooth, and a clutch mechanism connected between the first output tooth and the drive motor;

[0008] The clutch mechanism includes a clutch shaft, a clutch pin, and an output shaft. One end of the output shaft is provided with a clutch chamber, and the side of the clutch chamber is provided with a clutch recess. The clutch pin is located in the clutch chamber, and one end of the clutch shaft can be inserted into the clutch chamber.

[0009] When the clutch shaft rotates forward, it can move the clutch pin into the clutch recess to drive the output shaft to rotate. When the output shaft rotates in reverse, it can disengage the clutch pin from the clutch recess to disengage the clutch shaft from the output shaft.

[0010] The beneficial effects of the hand-flash integrated window opener provided in this application are as follows: Compared with the prior art, by setting a clutch shaft, clutch column and output shaft, when the clutch shaft rotates forward, it can move the clutch column to insert into the clutch recess to drive the output shaft to rotate; when the output shaft rotates in reverse, it can make the clutch column disengage from the clutch recess to disengage the clutch shaft from the output shaft.

[0011] With this structure, when switching from automatic to manual window opening and closing, the user only needs to rotate the second output tooth, which in turn drives the output shaft to rotate in the opposite direction via the first output tooth. This allows the clutch pin to disengage from the clutch recess and enter the clutch chamber, disengaging the clutch shaft from the output shaft. During this process, there is no need to use an additional nut to adjust the clutch state, thus simplifying the clutch switching operation and improving user convenience. At the same time, it effectively avoids the problem of teeth grinding caused by incomplete clutch engagement in traditional technologies, thereby improving the reliability and service life of the clutch mechanism.

[0012] As a preferred embodiment: the first output tooth is provided with a first mounting shaft hole, one end of the output shaft is inserted into the first mounting shaft hole, and the other end of the first mounting shaft hole is equipped with a first connecting shaft, which is used to connect the window connecting rod.

[0013] As a preferred embodiment: the first output tooth, the first connecting shaft, and the output shaft are coaxially arranged, and the central axis of the second output tooth is perpendicular to the central axis of the first output tooth.

[0014] As a preferred option, the clutch column has a hollow section that extends at least through its lower surface.

[0015] As a preferred embodiment, the clutch mechanism further includes a base, which is fixedly mounted on the drive motor; a first bushing is rotatably mounted on the base, with the drive shaft of the drive motor inserted into one end of the first bushing and the clutch shaft inserted into the other end of the first bushing.

[0016] As a preferred embodiment, the system also includes a main housing, which has a motor compartment, a clutch compartment, and a gear compartment from bottom to top; the drive motor is installed in the motor compartment, the clutch mechanism is installed in the clutch compartment, and the first output tooth, the second output tooth, and the first connecting shaft are installed in the gear compartment.

[0017] As a preferred embodiment: the base is provided with a first positioning notch, and the motor compartment is provided with a first positioning protrusion for insertion into the first positioning notch.

[0018] As a preferred embodiment, the lower end of the motor compartment is provided with a first stop protrusion. When the base and the drive motor are installed in the motor compartment, the first stop protrusion can stop against the lower end of the drive motor.

[0019] As a preferred embodiment: the output shaft is a stepped shaft structure with a first shaft body, a second shaft body and a third shaft body, the second shaft body is smaller than the first shaft body and the second shaft body, the second shaft body is equipped with a first bearing, and the clutch chamber is provided with a first mounting position for the first bearing to be installed.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Please refer to the following: Figures 1 to 6 The hand-held and electric integrated window opener provided in the embodiments of this application will now be described.

[0035] The integrated flashlight and handheld window opener includes a first output tooth 11, a second output tooth 12 meshing with the first output tooth 11, a drive motor 13 for driving the rotation of the first output tooth 11, and a clutch mechanism 14 connected between the first output tooth 11 and the drive motor 13. When automatically opening and closing the window, the drive motor 13 drives the clutch mechanism 14 to drive the first output tooth 11, which in turn drives the window's connecting rod to open and close. When manually opening and closing the window, the second output tooth 12 is rotated, driving the first output tooth 11 to disengage the clutch mechanism 14 from the first output tooth 11 and the drive motor 13. This allows the second output tooth 12 to drive the first output tooth 11 to rotate without affecting the drive motor 13, thus enabling manual opening and closing of the window by the second output tooth 12 driving the first output tooth 11.

[0036] In some embodiments of this application, the clutch mechanism 14 includes a clutch shaft 141, a clutch pin 142, and an output shaft 143. One end of the output shaft 143 is provided with a clutch chamber 1431, and the side of the clutch chamber 1431 is provided with a clutch recess 1432. The clutch pin 142 is disposed in the clutch chamber 1431, and one end of the clutch shaft 141 can be inserted into the clutch chamber 1431. When the clutch shaft 141 rotates forward, it can move the clutch pin 142 into the clutch recess 1432 to drive the output shaft 143 to rotate. When the output shaft 143 rotates in reverse, it can disengage the clutch pin 142 from the clutch recess 1432 to disengage the clutch shaft 141 from the output shaft 143.

[0037] Therefore, when switching from automatic to manual window opening and closing, the user only needs to rotate the second output tooth 12, which in turn drives the output shaft 143 to rotate in the opposite direction via the first output tooth 11. This allows the clutch pin 142 to disengage from the clutch recess 1432 and enter the clutch chamber 1431, thus disengaging the clutch shaft 141 from the output shaft 143. During this process, there is no need to use an additional nut to adjust the clutch state, which simplifies the clutch switching operation and improves user convenience. At the same time, it effectively avoids the problem of teeth grinding caused by incomplete clutch engagement in traditional technologies, thereby improving the reliability and service life of the clutch mechanism 14.

[0038] Preferably, a bearing is installed on the top of the clutch shaft 141, and a hole is provided on the top of the clutch chamber 1431 for the bearing to be installed, thereby enhancing the smoothness of rotation between the clutch shaft 141 and the output shaft 143; which helps to reduce the force required for the user to switch from automatic mode to manual mode.

[0039] Specifically, the first output tooth 11 is provided with a first mounting shaft hole 111, one end of the output shaft 143 is inserted into the first mounting shaft hole 111, and the other end of the first mounting shaft hole 111 is equipped with a first connecting shaft 112, which is used to connect the window connecting rod. The first output tooth 11, the first connecting shaft 112 and the output shaft 143 are coaxially arranged, and the central axis of the second output tooth 12 is perpendicular to the central axis of the first output tooth 11.

[0040] It should be noted that in this application, the drive shaft of the drive motor 13 and the first bushing 1441, the clutch shaft 141 and the first bushing 1441, the output shaft 143 and the first output tooth 11, and the first output tooth 11 and the first connecting shaft 112 are all connected and assembled by inserting a square shaft and a square hole.

[0041] In some other embodiments of this application, the clutch post 142 is provided with a hollow portion 1421, which at least extends through its lower surface; by providing a hollow clutch post 142, the clutch shaft 141 can more easily move the clutch post 142 into the clutch recess 1432, thereby improving the clutch reliability between the clutch shaft 141 and the output shaft 143.

[0042] Preferably, the clutch shaft 141 is provided with a shifting protrusion 1411, which gradually decreases in size from the center of the clutch post 142 to form a shifting slope. With the setting of this shifting slope, the clutch post 142 can be guided to move outward to engage in the clutch recess 1432 when the clutch shaft 141 rotates.

[0043] Specifically, the clutch mechanism 14 also includes a base 144, which is fixedly mounted on the drive motor 13. A first bushing 1441 is rotatably mounted on the base 144. The drive shaft of the drive motor 13 is inserted into one end of the first bushing 1441, and the clutch shaft 141 is inserted into the other end of the first bushing 1441. By using the base 144, the ease of assembly between the drive motor 13 and the clutch mechanism 14 can be improved, while ensuring the coaxiality between the drive shaft of the drive motor 13 and the clutch shaft 141.

[0044] In some embodiments of this application, a main housing 10 is also included, which is assembled from a bottom shell and a top cover. The main housing 10 is provided with a motor compartment 101, a clutch compartment 102 and a gear compartment 103 from bottom to top. The drive motor 13 is installed in the motor compartment 101, the clutch mechanism 14 is installed in the clutch compartment 102, and the first output tooth 11, the second output tooth 12 and the first connecting shaft 112 are installed in the gear compartment 103.

[0045] Specifically, the base 144 is provided with a first positioning notch 1442, and the motor compartment 101 is provided with a first positioning protrusion 1011 for insertion of the first positioning notch 1442. The lower end of the motor compartment 101 is provided with a first stop protrusion 1012. When the base 144 and the drive motor 13 are installed in the motor compartment 101, the first stop protrusion 1012 can stop against the lower end of the drive motor 13.

[0046] Preferably, the base 144 has a first notch 1443 at the top, and a sliding plate 1444 is installed in the first notch 1443. The sliding plate 1444 can close the bottom of the clutch chamber 1431 so that the clutch pin 142 can be moved into the clutch recess 1432 by moving the protrusion 1411 within the clutch chamber 1431.

[0047] In some other embodiments of this application, the output shaft 143 is a stepped shaft structure having a first shaft body 1433, a second shaft body 1434, and a third shaft body 1435. The second shaft body 1434 is smaller than the first shaft body 1433 and the second shaft body 1434. A first bearing 1436 is mounted on the second shaft body 1434. The clutch chamber 102 is provided with a first mounting position 1021 for the first bearing 1436 to be installed. The clutch cavity 1431 is located at the bottom of the third shaft body 1435.

[0048] More specifically, the first output gear 11 is equipped with a second bearing 113, and the gear compartment 103 is provided with a second mounting position 1031, where the second bearing 113 is mounted; the first connecting shaft 112 is equipped with a third bearing 114, and the gear compartment 103 is provided with a third mounting position 1032, where the third bearing 114 is mounted; this structure can improve the installation stability and rotation smoothness of the first output gear 11, the first connecting shaft 112, and the output shaft 143.

[0049] Preferably, the second output tooth 12 is exposed on the surface of the main housing 10. The second output tooth 12 is provided with a square hole into which a handle can be inserted for use in driving the second output tooth 12 to rotate.

[0050] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
