Description

Technical Field

[0001] This utility model relates to the field of outdoor furniture technology, specifically an outdoor pavilion with an openable and closable canopy. Background Technology

[0002] Outdoor pavilions, as a common recreational facility, are widely used in courtyards, parks, and commercial spaces due to their aesthetic appeal and practicality. Among them, canopies with opening and closing functions, especially louvered canopies, are increasingly favored by consumers because they can flexibly adjust shading and ventilation according to weather changes.

[0003] However, existing outdoor pavilions still have many shortcomings in terms of roof opening and closing functions.

[0004] On the one hand, the common methods for opening and closing outdoor gazebo roofs on the market can be mainly divided into two categories: Manual opening method: These types of pavilions are usually operated manually by a crank, rope, or simple mechanical linkage mechanism.

[0005] Disadvantages: The manual opening method has obvious limitations. First, the operation is relatively cumbersome and laborious, especially for canopies with a large area or many louvers, requiring users to spend a considerable amount of time and energy to complete the opening and closing. Second, when opening manually, users usually need to connect the crank handle to the reducer or transmission mechanism on the top of the gazebo to open and close the canopy. Since the crank handle itself may be long and bulky, it is inconvenient to store and affects the overall aesthetics of the gazebo. Even with some detachable crank handles, users still need to connect it to the high-mounted reducer each time they use it. This is not only difficult to operate and results in a poor user experience, but it is also extremely inconvenient for shorter or less mobile users.

[0006] Electric opening method: This type of pavilion uses a motor to drive a reducer to automatically open and close the louvers or roof, making it easy to operate.

[0007] Disadvantages: While the electric opening system offers convenience, it also has a fatal flaw. In the event of a power outage or electrical failure, the electric opening system will completely fail, preventing the roof from opening or closing properly. This means that during a power outage, users cannot open the roof to enjoy sunlight or ventilation, nor can they close it in time to cope with sudden severe weather (such as heavy rain), causing significant inconvenience and potential losses. Therefore, further improvements are necessary. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a simple structure, easy to use, and a pavilion louver opening structure that combines electric and manual opening functions, so as to improve the flexibility, reliability and user experience of the use of the pavilion.

[0009] The purpose of this utility model is achieved through the following means: an outdoor pavilion with an openable and closable canopy, comprising a main frame, with several columns extending downward from the bottom of the main frame, the columns supporting the main frame on the ground, several louvers installed inside the main frame, the two ends of the louvers being hinged to the main frame via hinge seats, the louvers being able to swing around the hinge point of the hinge seats, and a pull arm also being hinged to the hinge seat, the pull arm connecting the several louvers into one unit, when the pull arm moves, synchronously driving all the louvers to swing, thereby realizing the opening and closing of the canopy; The main frame is also equipped with a reducer, and a drive arm is connected to the output shaft of the reducer. The other end of the drive arm is hinged to the pull arm. It also includes a hand-operated and electric integrated window opener installed on the column. The output shaft of the hand-operated and electric integrated window opener is connected to the input shaft of the reducer through a transmission rod. The hand-operated and electric integrated window opener drives the transmission rod to rotate by electric drive or hand crank, thereby realizing the opening of the louvers.

[0010] The reducer is fixed to the outer side of the main frame. The output shaft of the reducer passes through the connection hole on the main frame and extends into the inner side of the main frame to connect with the drive arm.

[0011] The input shaft of the reducer extends vertically downwards.

[0012] The column is equipped with a rotating seat, the lower end of the transmission rod is connected to the integrated hand and electric window opener, and the upper end of the transmission rod is rotatably installed in the rotating seat.

[0013] The top of the transmission rod is connected to a driven rod via a first universal joint, and the other end of the driven rod is connected to the input shaft of the reducer via a second universal joint.

[0014] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0015] This invention creatively introduces a hand-operated and electric integrated window opener as a power source, which is connected to the input shaft of the reducer via a transmission rod. This allows the louvers of the gazebo roof to be opened and closed not only by electric motor for convenient automated operation, but also by hand-crank operation in the event of no power supply or electric system failure.

[0016] The dual-mode design greatly enhances the system's reliability and robustness, ensuring that users can still easily open or close the louvered roof in emergency situations such as power outages or malfunctions. This effectively avoids the predicament of existing electric gazebos where the roof cannot be operated during power outages, significantly improving user convenience and the ability to respond to emergencies.

[0017] 4. The installation height of the hand-operated and electric window opener can be flexibly adjusted according to the user's actual height and usage habits, so that users of different heights can operate it by hand in the most comfortable and effortless way.

[0018] 5. Compared to existing technologies that require users to connect the crank handle to the reducer on the top of the pavilion at a high altitude, this invention integrates the hand-crank mechanism into the window opener on the column, eliminating the need for complex handle connection. When hand-crank operation is required, it can be performed directly on the column, greatly simplifying the operation steps and reducing the difficulty of operation. Attached Figure Description

[0025] The present invention will now be further described in detail with reference to the accompanying drawings.

[0026] An outdoor pavilion with an openable and closable roof includes a main frame 1, with several columns 2 extending downward from the bottom of the main frame 1, supporting the main frame 1 on the ground. Several louvers 3 are installed inside the main frame 1, and the two ends of the louvers 3 are hinged to the main frame 1 through hinge seats 4. The louvers 3 can swing around the hinge point of the hinge seat 4. A pull arm 5 is also hinged to the hinge seat 4, and the pull arm 5 connects the several louvers 3 into one unit. When the pull arm 5 moves, it synchronously drives all the louvers 3 to swing, realizing the opening and closing of the roof. The main frame 1 is also equipped with a reducer 6, and a drive arm 7 is connected to the output shaft 61 of the reducer 6. The other end of the drive arm 7 is hinged to the pull arm 5. It also includes a hand-operated and electric integrated window opener 8 installed on the column 2. The output shaft of the hand-operated and electric integrated window opener 8 is connected to the input shaft 62 of the reducer 6 through the transmission rod 9. The hand-operated and electric integrated window opener 8 drives the transmission rod 9 to rotate by electric drive or hand crank drive, thereby realizing the opening of the louver 3.

[0027] In this embodiment, the core is that the louver 3 swings synchronously through the pull arm 5, and the driving force is provided by the hand-flash integrated window opener 8 and transmitted to the louver through the transmission chain.

[0028] Specifically, when it is necessary to open or close the ceiling, the user can operate the combined electric and manual window opener 8. This window opener has both electric and manual drive modes.

[0029] In electric mode, the motor inside the window opener drives its output shaft to rotate.

[0030] In manual mode, the user operates the window opener by hand to rotate its output shaft.

[0031] Whether it is electric or hand-cranked, the rotation of the output shaft of the window opener will be transmitted to the transmission rod 9, which in turn drives the input shaft 62 of the reducer 6 to rotate.

[0032] The function of the reducer 6 is to convert the input high speed and low torque into low speed and high torque, thereby providing sufficient force to drive the opening and closing of the roof. After receiving the reduced power, the output shaft 61 of the reducer 6 rotates, driving the drive arm 7 connected to it to swing.

[0033] Since the other end of the drive arm 7 is hinged to the pull arm 5, the swinging of the drive arm 7 will directly push or pull the pull arm 5. Since the pull arm 5 connects all the louvers 3 into one unit, the movement of the pull arm 5 will cause all the louvers 3 to swing synchronously around the hinge point of their respective hinge seats 4. When the louvers 3 swing from a horizontal state to a vertical state, the ceiling opens, and vice versa.

[0034] In one embodiment: the reducer 6 is fixed to the outer side of the main frame 1, and the output shaft 61 of the reducer 6 passes through the connection hole on the main frame 1 and extends into the inner side of the main frame 1 to connect with the drive arm 7.

[0035] In this embodiment, by fixing the reducer 6 to the outer side of the main frame 1, the reducer body does not occupy the internal space of the pavilion, maintaining the neatness and aesthetics of the interior. Simultaneously, the output shaft 61 of the reducer 6 extends into the main frame 1 after passing through the connecting hole, allowing direct connection to the drive arm 7 located inside the main frame. This design ensures the directness and effectiveness of power transmission, reduces intermediate transmission links, and improves transmission efficiency and reliability.

[0036] In one embodiment, the input shaft 62 of the reducer 6 extends vertically downward.

[0037] When the input shaft 62 of the reducer 6 extends vertically downwards, it facilitates direct or indirect connection with the transmission rod 9 extending from below. This vertical arrangement allows the entire transmission mechanism to transmit power along a relatively straight path, simplifying the design of the transmission mechanism and improving transmission efficiency and system stability.

[0038] In one embodiment: a rotating seat 21 is installed on the column 2, the lower end of the transmission rod 9 is connected to the integrated flashlight window opener 8, and the upper end of the transmission rod 9 is rotatably installed in the rotating seat 21.

[0039] In this embodiment, the rotating base 21 is mounted on the column 2, providing a stable rotational support point for the upper end of the transmission rod 9. The lower end of the transmission rod 9 is connected to the output shaft of the integrated flashlight window opener 8, responsible for receiving the driving force. The upper end of the transmission rod 9 is rotatably mounted inside the rotating base 21, ensuring that the transmission rod 9 remains centrally stable during rotation and avoiding wobbling, thereby stably transmitting the torque from the integrated flashlight window opener 8 to the input shaft 62 of the reducer 6. This design ensures the stability and smoothness of the transmission rod 9 during rotation, reduces friction and energy loss, and extends its service life. At the same time, the support of the rotating base also makes the transmission mechanism more compact and reliable.

[0040] In one embodiment: the top of the transmission rod 9 is connected to the driven rod 92 via a first universal joint 91, and the other end of the driven rod 92 is connected to the input shaft 62 of the reducer 6 via a second universal joint 93.

[0041] In summary, the core working principle of this case is to construct a highly efficient, reliable louvered ceiling drive system with multi-mode operation capabilities.

[0042] Its drive mechanism originates from the hand-operated electric window opener 8 mounted on the column 2. This hand-operated electric window opener 8 is a commonly used component in the market, and its specific structure can be found in patent number CN202421150639.3. The specific principle will not be described in detail here. During use, users can choose to operate it electrically via its internal motor to enjoy the convenience of automation; alternatively, it can be operated manually in the event of a power outage or emergency, fully demonstrating the advantages of dual-mode drive and emergency function.

[0043] The power generated by the window opener is transmitted through the transmission rod 9. The transmission rod 9 is stably supported on the column 2 by the rotating seat 21, ensuring smooth transmission. To accommodate possible axial misalignment, the top of the transmission rod 9 is cleverly connected to the input shaft 62 of the reducer 6 via the driven rod 92 and the first universal joint 91 and the second universal joint 93. This not only improves the system's installation tolerance but also ensures the smoothness of power transmission.

[0044] The reducer 6, receiving power, will reduce speed and increase torque, and its output shaft 61 will drive the drive arm 7 to rotate. Since the drive arm 7 is hinged to the pull arm 5, the pull arm 5 will move in tandem with all the louvers 3, ultimately realizing the opening and closing of the pavilion roof. The reducer 6 is cleverly fixed to the outside of the main frame 1, and its output shaft passes through the main frame and connects to the internal mechanism, taking into account both aesthetics and functionality.

[0045] In summary, this utility model, through its integrated hand-flash drive mechanism, optimized transmission path, and reasonable component layout, not only solves the drawbacks of the existing single drive mode of pavilions and provides a more flexible, reliable, and convenient opening and closing experience, but also achieves higher integration and aesthetics in its structure, greatly improving the functionality and user satisfaction of outdoor pavilions.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
