Description

Technical Field

[0001] The present application relates to the field of shutter drive technology, and in particular to a shutter flipping and opening and closing drive device. Background Art

[0002] There are many types of outdoor awnings on the market, including those with integrated tops and those with louvers installed on the tops. Among them, the louvers of outdoor awnings with louvers installed on the tops can be flipped to let sunlight and air pass through, making the outdoor experience better; even the louvers can be opened and closed as a whole, allowing the top to be fully open, so as to get closer to the outdoors.

[0003] An outdoor awning with flippable and openable shutters is installed on the top. There are generally two ways to drive the shutters to flip and open and close, one is electric drive and the other is manual drive.

[0004] The method of electrically driving the flipping and opening of the blinds is: two motors are used to drive the flipping and opening of the blinds respectively; in this method, the motor and the related transmission mechanism are installed on the top of the awning, and the flipping and opening of the blinds are driven separately, and the structure is relatively simple; but because it is driven by a motor, it needs to be powered. If an external power supply is used, it is not convenient for outdoor use. If a battery is added inside the awning, problems such as charging and waterproofing will be involved; at the same time, the use of motors will increase the cost of the awning.

[0005] The manual method of driving the shutters to flip and open is: use a long rocker, first align it with the transmission mechanism on the top of the awning, and then turn the crank set on the long rocker to drive the shutters to move. This method has a simple structure and low cost. However, on the one hand, since the transmission mechanism is set on the top of the awning, it is troublesome to align or take down the long rocker; on the other hand, since the long rocker is generally set at the four corners of the awning and is close to the column, turning the crank is easy to hit the column, affecting the smooth flipping and opening and closing of the shutters; in addition, to drive the shutters to flip and drive the shutters to open and close, it is necessary to first align the long rocker with the transmission mechanism responsible for the flipping of the shutters, and then take the long rocker off and put it on the transmission mechanism responsible for the opening and closing of the shutters, that is, it is necessary to align the transmission mechanism twice, and when driving the shutters to flip or open and close, one hand needs to hold the long rocker and the other hand needs to turn the crank. It can be seen that the manual operation of driving the shutters to flip and open and close is complicated and inconvenient, time-consuming and labor-intensive, and the experience is poor.

[0078] In order to solve the problems in the above-mentioned background technology, the present application provides a blinds flipping and opening and closing drive device, which drives the blinds to open and close by lifting the shift handle and turning the crank, and drives the blinds to flip by the operating mechanism, the drive shaft mechanism and the transmission mechanism; and moves the shift handle downward and turns the crank, and drives the blinds to flip by the operating mechanism, the drive shaft mechanism and the transmission mechanism; thereby, through a simple mechanical structure, the convenience of manually driving the blinds to open and close and flip is greatly increased, and the technical problems of the existing blinds flipping and opening and closing drive devices with complex structures, inconvenient operations and poor user experience are solved.

[0079] At the same time, in order to make the purpose, technical solutions and advantages of this application more clear, the technical solutions in the embodiments of this application are further described in detail through the following embodiments and in combination with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0080] like Figure 1 As shown, the present application provides a shutter flipping and opening and closing driving device. In this embodiment, the shutter flipping and opening and closing driving device comprises: a transmission shaft mechanism 1, an operating mechanism 2 and a transmission mechanism 3.

[0081] In a specific embodiment, if Figure 1 as well as Figure 2As shown, the transmission shaft mechanism 1 comprises: a first transmission shaft 11, a second transmission shaft 12 and a third transmission shaft 13. The two ends of the second transmission shaft 12 are fixedly connected to the first transmission shaft 11 through a first coupling 14, and are fixedly connected to the third transmission shaft 13 through a second coupling 15.

[0082] like Figure 3 As shown, the operating mechanism 2 includes a shift operating component 21 and a transmission operating component 22 .

[0083] In one embodiment, the shift control assembly 21 includes: a shift handle 211, a joint bearing 212, and a lifting frame 213 whose two ends are respectively fixedly connected to the shift handle 211 and the joint bearing 212. The lifting frame 213 is fixedly connected to the transmission shaft mechanism 1. Specifically, the lifting frame 213 is fixedly connected to the first transmission shaft 11.

[0084] In a specific embodiment, if Figure 3 As shown, the lifting frame 213 includes an outer frame 213a, an inner frame 213b and a lifting shaft 213c.

[0085] The two ends of the outer frame 213a are respectively fixedly connected to the shift handle 211 and the joint bearing 212. Specifically, the raised portion of the outer frame 213a is installed on the inner ring of the joint bearing 212 and fixed by the end locking nut. It should be noted that the position of the joint bearing 212 is fixed, but a certain gap is left between the raised portion of the outer frame 213a and the inner ring of the joint bearing 212, so the outer frame 213a has a certain degree of mobility. Due to the fixing effect of the end locking nut, the outer frame 213a can rotate up and down along the joint bearing 212 in a vertical plane without being separated from the joint bearing 212.

[0086] The outer frame 213a is provided with a waist-shaped groove near the shift handle 211. The lifting shaft 213c is fixedly connected to the inner frame 213b and inserted into the waist-shaped groove; and the inner frame 213b is fixedly connected to the first transmission shaft 11. Therefore, the shift handle 211 can move between a first set position and a second set position. When the shift handle 211 moves, it drives the lifting frame 213 to rotate along the joint bearing 212, thereby driving the transmission shaft mechanism 1 to move up and down in the vertical direction. Specifically, after lifting the shift handle 211 and driving the outer frame 213a to rotate upward along the joint bearing 212, the lifting shaft 213c can be driven to move in the waist-shaped groove in a direction away from the shift handle 211, such as Figure 3As shown, the lifting shaft 213c will move rightward in the waist-shaped groove, thereby driving the inner frame 213b, the first transmission shaft 11, the second transmission shaft 12 and the third transmission shaft 13 to move upward; at the same time, the shift handle 211 is moved downward, and the outer frame 213a is driven to rotate downward along the joint bearing 212, which can drive the lifting shaft 213c to move in the waist-shaped groove toward the shift handle 211, as shown in FIG. Figure 3 As shown, the lifting shaft 213c will move leftward in the waist-shaped groove, thereby driving the inner frame 213b, the first transmission shaft 11, the second transmission shaft 12 and the third transmission shaft 13 to move downward.

[0087] It should be noted that by moving the lifting shaft 213c left and right in the waist-shaped groove, the inner frame 213b can be limited to move only in the vertical direction without any displacement in the horizontal direction, so that the first transmission shaft 11, the second transmission shaft 12 and the third transmission shaft 13 can only move up and down in the vertical direction.

[0088] In this embodiment, a support bearing is installed at the lower end of the first transmission shaft 11, and the support bearing is pressed into the bearing hole set in the inner frame 213b. The support bearing is fixed by a locking nut at the end of the shaft, thereby realizing a fixed connection between the first transmission shaft 11 and the inner frame 213b, and realizing that the first transmission shaft 11 is driven to move upward or downward by the inner frame 213b without affecting the rotation of the first transmission shaft 11.

[0089] In one embodiment, if Figure 3 As shown, the shift control assembly 21 further includes a guide shaft 214 and a plurality of linear bearings 215 .

[0090] The guide shaft 214 is fixedly connected to the inner frame 213b and is parallel to the first transmission shaft 11. Specifically, the guide shaft 214 is fixed near the shift handle 211, and the guide shaft 214 is press-fitted into the bearing hole of the inner frame 213b through a support bearing. Lift the shift handle 211 and move it to the first set position, drive the outer frame 213a to rotate upward along the joint bearing 212, and drive the lifting shaft 213c to move in the waist-shaped groove toward the shift handle 211, thereby driving the inner frame 213b and the guide shaft 214 to move upward in unison with the first transmission shaft 11; at the same time, move the shift handle 211 downward and move it to the second set position, drive the outer frame 213a to rotate downward along the joint bearing 212, and drive the lifting shaft 213c to move in the waist-shaped groove away from the shift handle 211, thereby driving the inner frame 213b and the guide shaft 214 to move downward in unison with the first transmission shaft 11.

[0091] Each linear bearing 215 is respectively disposed on the first transmission shaft 11 and the guide shaft 214, and is used to support the first transmission shaft 11 and the guide shaft 214, and to limit the movement direction of the first transmission shaft 11 and the guide shaft 214. In a preferred embodiment, Figure 3 As shown, three linear bearings 215 are used, wherein two linear bearings 215 are installed on the first transmission shaft 11, and the third linear bearing 215 is installed on the guide shaft 214. Through the guide shaft 214 parallel to the first transmission shaft 11 and the three linear bearings 215, it can be effectively ensured that the first transmission shaft 11 only moves in the vertical direction and always maintains linear motion. At the same time, the stiffness of the first transmission shaft 11 during linear motion is improved, ensuring that the first transmission shaft 11 moves smoothly, thereby ensuring that the entire shutter flip opening and closing drive device shifts and transmits smoothly.

[0092] In one embodiment, if Figure 3 As shown, the shift control assembly 21 further includes a buffer spring 216 and a limiting slot plate 217 .

[0093] The buffer spring 216 is sleeved on the raised portion at the lower end of the inner frame (213b). Preferably, the buffer spring 216 is a compression spring, which is used, on the one hand, to support the inner frame (213b) when the shift handle 211 is lifted to prevent it from falling, thereby ensuring that the shutter flipping and opening driving device can smoothly drive the shutter to open and close and flip smoothly; on the other hand, it is used to prevent the shift handle 211 from falling suddenly when it is moved downward to avoid impact damage to the device.

[0094] The limiting groove plate 217 is disposed between the shift handle 211 and the outer frame 213a and is provided with a folding groove; the folding groove limits the movement direction of the shift handle 211 and supports the shift handle 211 in a specified position. Figure 3 As shown, after the shift handle 211 is lifted, the shift handle 211 can be stuck in the folding groove to prevent the shift handle 211 from suddenly falling due to gravity and causing shift failure, thereby ensuring that the shutter flipping and opening drive device can smoothly drive the shutter to open and close and the flipping process is smooth.

[0095] In one embodiment, the transmission control assembly 22 includes: a crank 221 (see Figure 1 ), a power input shaft 222 fixedly connected to the crank handle 221, a first bevel gear 223 fixedly connected to the power input shaft 222, and a second bevel gear 224 fixedly connected to the first transmission shaft 11 and meshing with the first bevel gear 223.

[0096] In this embodiment, the transmission control assembly 22 is used to provide and transmit power, and the specific method includes: rotating the crank handle 221, driving the power input shaft 222 to rotate, and in turn driving the first bevel gear 223, the second bevel gear 224, the first transmission shaft 11, the second transmission shaft 12 and the third transmission shaft 13 to rotate, thereby providing power for the transmission mechanism 3.

[0097] It should be noted that two support bearings are installed on the power input shaft 222, and the two support bearings are installed on both sides of the first bevel gear 223, respectively, for limiting the first bevel gear 223 to rotate only under the drive of the power input shaft 222; two support bearings are also installed on the first transmission shaft 11, and the two support bearings are installed on both sides of the second bevel gear 224, respectively, and the inner ring of each support bearing abuts against the outer ring step of the second bevel gear 224, and is fixed by an end locking nut. The inner ring of the second bevel gear 224 cooperates with the outer ring of the first transmission shaft 11, such as providing mutually cooperating vertical key teeth, so that the first transmission shaft 11 can drive the second bevel gear 224 to rotate, but does not affect the up and down movement of the first transmission shaft 11, and does not move up and down with the first transmission shaft 11.

[0098] In a preferred embodiment, the first bevel gear 223 and the second bevel gear 224 are 90° bevel gears, so that the power input shaft 222 and the first transmission shaft 11 are distributed at 90°, saving space. In addition, the crank handle 211 can be set at a convenient position for users to operate, which is convenient for users to operate and saves trouble and effort.

[0099] In one embodiment, the control mechanism 2 further includes: a control frame assembly 23. Figure 6 As shown, a plurality of limiting grooves are arranged inside the operating frame assembly 23 for installing and supporting the shift operating assembly 21 and the transmission operating assembly 22 .

[0100] Specifically, the operating frame assembly 23 is provided with a plurality of gear grooves for installing and supporting the bevel gears in the transmission operating assembly 22, and a certain movable space is left for each bevel gear to allow each bevel gear to rotate in a specified direction; and, the operating frame assembly 23 is also provided with a plurality of bearing grooves adapted to each support bearing for installing and supporting the shift operating assembly 21 and each support bearing, each linear bearing and the spherical bearing 212 in the transmission operating assembly 22, and a plurality of shaft grooves adapted to each shaft for installing and supporting the lifting shaft 213c, the guide shaft 213, the power input shaft 222 and the first transmission shaft 11, so as to better support each bevel gear, each shaft and other components, and confine each bevel gear, each shaft and other components inside the operating frame assembly 23, so that each bevel gear, each shaft or other components is limited to move only in a specified direction.

[0101] It should be noted that, for each support bearing, each linear bearing and the joint bearing 212 that need to be fixed, they are respectively abutted against their corresponding bearing grooves, and each bearing groove completely limits its mobility, thereby achieving the fixing function; for movable parts, such as the lifting frame 213, the operating frame assembly 23 retains a certain amount of activity space in the specified direction.

[0102] In a specific embodiment, if Figure 6 As shown, the control frame assembly 23 includes two parts: a first control frame shell 231 and a second control frame shell 232, and the first control frame shell 231 and the second control frame shell 232 are detachably connected. In this embodiment, the shutter flipping and opening and closing drive device can be used for the opening, closing and flipping of the shutters arranged on the top of the awning. Specifically, the first control frame shell 231 and the second control frame shell 232 can be installed in a column of the awning through one or more mounting parts, and installed in cooperation with each other to form the control frame assembly 23, thereby supporting the control structure 2 and fixing the control mechanism 2 in the column, maintaining the overall beauty of the awning and meeting user needs.

[0103] like Figure 4 As shown, the transmission mechanism 3 includes: a shift assembly 31 , an opening and closing transmission assembly 32 and a flip transmission assembly 33 .

[0104] In one embodiment, the shift assembly 31 includes: a first shift spur gear 311 meshed with the opening and closing transmission assembly 32, a second shift spur gear 312 meshed with the flip transmission assembly 33, and a shift mechanism disposed between the first shift spur gear 311 and the second shift spur gear 312 and fixedly connected to the transmission shaft mechanism 1. Preferably, the shift mechanism includes a shift spline 313; when the shift handle 211 moves to the first set position, the shift spline 313 meshes with the first shift spur gear 311; when the shift handle 211 moves to the second set position, the shift spline 313 meshes with the second shift spur gear 312.

[0105] In a specific embodiment, the shift spline 313 is fixedly connected to the third transmission shaft 13. Support sleeves are installed at both ends of the third transmission shaft 13, and support bearings are installed at both ends of the first shift spur gear 311 and the second shift spur gear 312. The support sleeves and support bearings at adjacent positions abut against each other to jointly support the shift assembly 31 and improve the rigidity of the shift assembly 31.

[0106] like Figure 5 As shown, the first shift spur gear 311 and the second shift spur gear 312 are hollow inside, do not contact the third transmission shaft 13, and do not receive the power transmitted by the third transmission shaft 13. The first shift spur gear 311 and the second shift spur gear 312 are provided with guide grooves adapted to the key teeth of the shift spline 313 at the positions relative to the shift spline 313, so as to smoothly mesh with the shift spline 313. When the third transmission shaft 13 moves upward, the shift spline 313 is driven to move upward and mesh with the first shift spur gear 311, thereby transmitting the power to the first shift spur gear 311; when the third transmission shaft 13 moves downward, the shift spline 313 is driven to move downward and mesh with the second shift spur gear 312, thereby transmitting the power to the second shift spur gear 312.

[0107] In this embodiment, the method of manipulating the shift assembly 31 to switch the opening and closing function and the flipping function through the shift control assembly 21 includes: lifting the shift handle 211, the shift handle 211 moves to the first set position, drives the lifting frame 213 to rotate upward along the joint bearing 212, and drives the transmission shaft mechanism 1 to move upward, so that the shift spline 313 moves upward and engages with the first shift spur gear 311, thereby switching to the opening and closing function, so as to rotate the opening and closing transmission assembly 32 through the transmission control assembly 22, and drive the blinds of the awning to open and close; moving the shift handle 211 downward, the shift handle 211 moves to the second set position, drives the lifting frame 213 to rotate downward along the joint bearing 212, and drives the transmission shaft mechanism 1 to move downward, so that the shift spline 313 moves downward and engages with the second shift spur gear 312, thereby switching to the flipping function, so as to rotate the flipping transmission assembly 33 through the transmission control assembly 22, and drive the blinds of the awning to flip.

[0108] Therefore, the shutter flipping and opening and closing driving device realizes the opening and closing function by lifting the shift handle 211, and drives the shutters of the awning to open and close; and realizes the flipping function by moving the shift handle 211 downward, and drives the shutters of the awning to flip.
