Description

Technical Field

[0001] This utility model belongs to the technical field of sunshade tools and relates to a louvered awning. Background Technology

[0002] Venetian awnings are a common tool in the prior art used for sun and rain protection. For example, Chinese Patent (Authorization Announcement No.: CN221030913U) discloses a louver stacking and retraction mechanism for outdoor louver awnings. It includes a louver awning top, which includes several louvered panels and a ring beam for mounting and cooperating with the louvered panels. It also includes a telescopic transmission mechanism, which includes a synchronous belt assembly. The synchronous belt assembly includes a synchronous pulley and a synchronous belt. A drive seat is provided on the synchronous belt. The drive seat is used to cooperate with the louvered panels located at the end positions. The synchronous belt drives the drive seat to move, and drives the outermost louvered panel to move. As the outermost louvered panel moves, it abuts against the adjacent louvered panels in sequence, and completes the stacking and retraction of several louvered panels.

[0003] According to paragraphs 0035 to 0037 of the prior art, the louvered awning has the function of stacking louvers. Specifically, it uses a telescopic drive motor as a power source, which, together with a synchronous pulley, connects to the farthest louver via a synchronous belt (specifically, the synchronous belt is connected and fixed to the drive seat at the end of the farthest louver). Stacking ropes connect the drive seats at the ends of several louvers. When it is necessary to retract, the synchronous belt pulls the farthest louver, realizing the stacked louvers adhering to adjacent louvers and sequentially completing the stacking and retraction of several louvers [described in paragraph 0036 of the specification]. Conversely, the synchronous belt is controlled to reverse, which pulls the farthest louver towards the drive wheel via the stacking ropes, sequentially driving the gradual unfolding of the entire louver [described in paragraph 0037 of the specification].

[0004] However, each louver panel has a considerable weight. Although the louvers are slidably connected to the ring beam via the first roller through the drive seat, the reaction force acting on the stacking rope during actual operation is still quite significant. Furthermore, to unfold several louvers, the stacking rope needs to overcome the weight of the louvers, thus greatly affecting the lifespan of the stacking rope and leading to frequent malfunctions in the louver panel unfolding and retraction function of the awning. Secondly, in the aforementioned comparative document, after stacking several louvers, the louvers are located at one end of the ring beam. This easily causes the ring beam to become unbalanced at both ends due to the stacking of the louvers, potentially causing the entire awning to tip over, posing a safety hazard. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a louvered awning. The technical problem this invention aims to solve is: how to reduce the failure rate while improving safety during use.

[0006] The objective of this utility model can be achieved through the following technical solution: A louvered awning includes a rectangular frame and a plurality of louvers arranged side by side along the length of the frame. The louvers are characterized by being divided into outer louver one, inner louver one, outer louver two, inner louver two, a plurality of sliding louver one located between outer louver one and inner louver one, and a plurality of sliding louver two located between outer louver one and inner louver two. Outer louver one and outer louver two are located at both ends of the frame, and inner louver one and inner louver two are adjacent and located in the middle of the frame. Both ends of outer louver one are hinged to a fixing seat one fixed to the frame, and both ends of outer louver two are hinged to a fixing seat two fixed to the frame. Several sliding louvers 1 are hinged to sliding seats 1 at both ends, and inner louvers 2 and several sliding louvers 2 are hinged to sliding seats 2 at both ends. Each sliding seat 1 and each sliding seat 2 is slidably connected to the frame. The sliding seat 1 at one end of each sliding louver 1 and the fixed seat 1 at one end of each outer louver 1 are connected in series by a steel wire 1. The sliding seat 2 at one end of each sliding louver 2 and the fixed seat 2 at one end of each outer louver 2 are connected in series by a steel wire 2. A synchronous belt is provided on one side of the frame along the length of the frame. The sliding seat 1 hinged to the inner louver 1 is fixedly connected to the upper belt body of the synchronous belt. The sliding seat 2 hinged to the inner louver 2 is fixedly connected to the lower belt body of the synchronous belt. The synchronous belt is driven by a servo motor connected to the frame.

[0007] The working principle of this louvered awning is as follows: When all the louvers are in the flipped-open state, the synchronous belt is driven to rotate by a servo motor. During this process, one of the sliding seats connected to the upper side of the synchronous belt pushes the inner louver 1 towards the outer louver 1, and one of the sliding seats connected to the lower side of the synchronous belt pushes the inner louver 2 towards the outer louver 2. Under the continuous pushing action, the sliding seat 1 connected to the inner louver 1 gradually pushes several sliding seats 1 connected to the inner louver 1 towards the fixed seat 1, and the sliding seat 2 connected to the inner louver 2 gradually pushes several sliding seats 2 connected to the inner louver 2 towards the fixed seat 2. This causes the inner louver 1, several sliding louver 1, and outer louver 1 to fold up at one end of the frame, while the inner louver 2, several sliding louver 2, and outer louver 2 fold up at the other end of the frame. Conversely, when the synchronous belt is driven to rotate in the opposite direction by the servo motor, the sliding seats 1 and 2 connected to the inner louver 1 are pushed by the synchronous belt towards the fixed seat 2. The frame is pulled in the middle. Under the traction of the first steel wire, the sliding seat connected to the inner louver 1 pulls the sliding seat connected to the sliding louver 1 towards the middle of the frame. At the same time, the sliding seat connected to the inner louver 2 pulls the sliding seat connected to the sliding louver 2 towards the middle of the frame. Meanwhile, the outer louver 1, which is fixed to one end of the frame by the fixed seat 1, and the outer louver 2, which is fixed to the other end of the frame by the same fixed seat, remain stationary at both ends of the frame. This allows the outer louver 1, outer louver 2, several sliding louver 1, several sliding louver 2, inner louver 1, and inner louver 2 to be spread out within the frame. This ensures that when the louvers are stacked and folded, they are moved towards both ends of the frame, effectively avoiding imbalance in the center of the louvered awning caused by unilateral folding, thus ensuring safety during use. Furthermore, the two steel wires work together to complete the folding and spreading of several louvers, achieving a significant reduction in the load on the steel wires during operation, thereby reducing the failure rate of the louvered awning.

[0008] In the aforementioned louvered awning, a connecting seat is fixed near the middle of the lower side of the synchronous belt. The connecting seat includes a seat body and a connecting plate fixed to the top of the seat body. A belt threading gap is formed between the connecting plate and the seat body. The upper side of the synchronous belt passes through the belt threading gap. A locking plate is fixed to the bottom of the seat body, and the locking plate presses the lower side of the synchronous belt against the bottom wall of the seat body. A slot is provided on the connecting plate, and the top of the sliding seat at one end of the inner louver is engaged in the slot. The connecting seat clamps and fixes the upper belt body of the synchronous belt through the cooperation of the seat body and the locking plate. Then, the belt body of the lower belt body of the synchronous belt is allowed to pass through the belt through the belt-passing gap formed between the connecting plate and the seat body to avoid interference with the synchronous belt during operation. The connecting plate is engaged with the top of the sliding seat of the inner louver by the slot. This allows the upper belt body of the synchronous belt to push the sliding seats of the inner louver and several sliding louvers to move towards the fixed seat. This allows the inner louver, several sliding louvers and outer louvers to be folded up at one end of the frame.

[0009] In the aforementioned louvered canopy, a connecting seat two is fixed near the middle of the lower side of the synchronous belt. The connecting seat two includes a seat plate located above the upper side of the synchronous belt and a locking plate two located below the upper side of the synchronous belt. The seat plate and the locking plate two are fixedly connected and clamp the upper side of the synchronous belt. A slot two is provided on the seat plate, and the top of the sliding seat two at one end of the inner louver two is engaged in the slot two. The connecting seat two clamps the lower side of the synchronous belt through the cooperation of the seat plate and the locking plate two, and engages with the top of the sliding seat two connecting the inner louver two through the slot two provided on the seat plate. This allows the lower side of the synchronous belt to push each sliding seat two connecting the inner louver two and several sliding louver two towards the fixed seat two, so that the inner louver two, several sliding louver two and the outer louver two can be folded up at the other end of the frame.

[0010] In the aforementioned louvered awning, horizontal perforations are provided on the top sidewalls of the fixed base 1 and each sliding base 1 connected by a steel wire 1, and the fixed base 2 and each sliding base 2 connected by a steel wire 2. Vertical fixing holes are provided on the top of the fixed base 1 and each sliding base 1 connected by a steel wire 1, and the fixed base 2 and each sliding base 2 connected by a steel wire 2. Steel wire 1 passes through the perforations on the fixed base 1 and several sliding bases 1, and steel wire 2 passes through the perforations on the fixed base 2 and several sliding bases 2. A screw 1 is screwed into the fixing holes on the fixed base 1 and several sliding bases 1 to tighten steel wire 1, and a screw 2 is screwed into the fixing holes on the fixed base 2 and several sliding bases 2 to tighten steel wire 2. This ensures the connection stability of steel wire 1 and steel wire 2, and ensures the linkage between the fixed base 1 and several sliding bases 1, and the linkage between the fixed base 2 and several sliding bases 2.

[0011] In the aforementioned louvered awning, a servo motor is fixed to one end of the frame, and a drive shaft parallel to the servo motor's drive end is rotatably connected to that end of the frame. The drive shaft and the servo motor are connected via a drive belt. Supports are fixed at both ends of the frame on the side with the synchronous belt, and tension pulleys are rotatably connected to each support. The drive shaft and tension pulleys are fixedly connected, and the synchronous belt is tensioned at both ends outside the tension pulleys on the two supports. The two supports use the tension pulleys to tension the synchronous belt, and the servo motor, through the drive belt and drive shaft, drives the tension pulley in one of the supports to rotate clockwise or counterclockwise, thereby enabling the synchronous belt to move connecting seat one and connecting seat two.

[0012] In the aforementioned louvered awning, two pairs of clamping blocks are fixed on one side of the frame between two supports, with a limiting gap formed between each pair of clamping blocks. Fixing seat one is embedded in one of the limiting gaps, and fixing seat two is embedded in the other limiting gap. This ensures the secure positioning of fixing seat one and fixing seat two.

[0013] In the aforementioned louvered awning, bearings are fixed to the first fixed base, several first sliding bases, the second fixed base, and several second sliding bases. The first outer louver blade is engaged with the inner ring of the bearing on the first fixed base via a pivot at its end. The second outer louver blade is engaged with the inner ring of the bearing on the second fixed base via a pivot at its end. The first inner louver blade and several first sliding louver blades are engaged with the inner ring of the bearing on the first sliding base via a pivot at their ends. The second inner louver blade and several second sliding louver blades are engaged with the inner ring of the bearing on the second sliding base via a pivot at their ends. The bearing arrangement allows the first outer louver blade to rotate relative to the first fixed base around its hinge point, the second outer louver blade to rotate relative to the second fixed base around its hinge point, the first and second movable louver blades to rotate relative to the first sliding base around their hinge point, and the second movable louver blades to rotate relative to the second sliding base around their hinge point. This ensures that the louvered awning, while providing the function of folding each louver blade on both sides, does not affect the rotational opening and closing function of each louver blade.

[0014] In the aforementioned louvered awning, a sliding connecting rod is provided inside the frame on one side of the synchronous belt, and a push rod motor is hinged inside the frame below the sliding connecting rod. The drive end of the push rod motor is connected to a long push rod. Several reversing connecting rods that are hinged to the inner wall of the frame are fixed between the push rod and the sliding connecting rod. Several swing arms with one end fixed to a transfer shaft are provided between the sliding connecting rod and the first fixed seat, several first sliding seats, the second fixed seat, and several second sliding seats. Each swing arm is engaged with the inner ring of the bearing on the first fixed seat, several first sliding seats, the second fixed seat, and several second sliding seats through the transfer shaft. The other end of each swing arm is rotatably connected to the sliding connecting rod and can slide along the length direction of the sliding connecting rod. The opening and closing of each louver is controlled by a push rod motor in conjunction with a push rod. The reversing linkage is used as the force point to push the sliding linkage to swing inside the frame. The swing arm, which is hinged to the reversing linkage, drives the inner rings of the bearings in the fixed seat 1, fixed seat 2, each sliding seat 1, and each sliding seat 2 to rotate. This causes the inner rings of the bearings to drive the rotating shafts of each louver to rotate synchronously, thereby controlling the rotation of the louvers to open and close.

[0015] In the aforementioned louvered awning, a sliding groove is provided along the length of the sliding connecting rod, and several rolling wheels are rolled within the sliding groove. Each swing arm is hinged to a corresponding rolling wheel. This allows the swing arms to swing relative to the sliding wheels, and during the folding and unfolding of the louvers, the rolling wheels in the sliding groove make way for each other, avoiding interference.

[0016] Compared with existing technologies, this louvered awning has the following advantages: by folding several sliding louver blades one and inner louver blades one towards outer louver blades one, all three are folded at one end of the frame, and by folding several sliding louver blades two and inner louver blades two towards outer louver blades two, all three are folded at the other end of the frame, the instability of the center of gravity that may occur when folding on one side is avoided. While ensuring safety in use, the reverse force when the two steel wires are pulled back and spread is reduced, thereby effectively reducing the failure rate of the louvered awning.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figure 1 , Figure 2 as well as Figure 4 As shown, this louvered awning includes a rectangular frame 1 and several louvers arranged side by side along the length of the frame 1. The louvers are divided into outer louver 11a, inner louver 11b, outer louver 2 11c, inner louver 2 11d, several sliding louvers 11e located between outer louver 11a and inner louver 11b, and several sliding louvers 2 11f located between outer louver 2 11c and inner louver 2 11d. Outer louvers 11a and outer louver 2 11c are located at both ends of the frame 1, and inner louvers 11a and 11b are arranged side by side. b and inner louver 11d are adjacent and located in the middle of frame 1. Both ends of outer louver 11a are hinged to fixed seats 11a1 fixed to frame 1. Both ends of outer louver 11c are hinged to fixed seats 11c1 fixed to frame 1. Both ends of inner louver 11b and several sliding louver 11e are hinged to sliding seats 2a. Both ends of inner louver 11d and several sliding louver 11f are hinged to sliding seats 2b. Each sliding seat 2a and each sliding seat 2b is slidably connected to frame 1. Figure 5-8A servo motor 13, specifically a tubular servo motor, is fixed to one end of the frame 1. A transmission shaft 14, parallel to the drive end of the servo motor 13, is rotatably connected to this end of the frame 1. The drive end of the servo motor 13 and the transmission shaft 14 are connected by a transmission belt 131. Slide grooves are provided along the length direction on both sides of the frame 1. Several sliding seats 2a and 2b are slidably connected in the slide grooves. Fixed seats 11a1 and 11c are fixed seats 11a1 and 11c. 1. Fixed in the slide groove, specifically, each sliding seat 2a and each sliding seat 2b is rotatably connected to a roller at its bottom. Each sliding seat 2a and each sliding seat 2b abuts against the inner wall of the slide groove through the roller. One end of the frame 1 is fixed to a bracket 15 by fasteners. Each bracket 15 is rotatably connected to a tension wheel 151. A synchronous belt 12 is tensioned between the tension wheels 151 of the two brackets 15. The end of the drive shaft 14 is connected and fixed to the tension wheel 151 on one of the brackets 15. When the servo motor 13 is running, it sequentially transmits power to the tension wheel 151 of one of the brackets 15 through the drive belt 131 and the drive shaft 14. The clockwise or counterclockwise rotation of the synchronous belt 12 is achieved by the cooperation of the tension wheels 151 on the two sets of brackets 15.

[0034] One side of the frame 1 is located between two supports 15 and is fixed with clamping blocks 16 located on the bottom wall of the slide groove by fasteners. Each clamping block 16 is L-shaped and a limiting gap 161 is formed between each pair of clamping blocks 16. Fixing seat 11a1 is stuck in one of the limiting gaps 161, and fixing seat 21c1 is stuck in the other limiting gap 161.

[0035] Combination Figure 9 A connecting seat 9a is fixed on the lower side of the synchronous belt 12, and a connecting seat 9b is fixed on the upper side of the synchronous belt 12. Specifically, the connecting seat 9a includes a seat body 9a1 and a connecting plate 9a2 welded and fixed (or directly integrally formed) on the top of the seat body 9a1. The connecting plate 9a2 and the seat body 9a1 together form a belt threading gap 9a3. The upper side of the synchronous belt 12 passes through the belt threading gap 9a3. The lower side of the seat body 9a1 and the upper side of the lower side of the synchronous belt 12 abut against each other. A locking plate 9a11 is fixed to the bottom of the seat body 9a1 and below the lower side of the belt body by fasteners. The locking plate 9a11 and the bottom wall of the seat body 9a1 cooperate to clamp the lower side of the synchronous belt 12. A slot 9a21 is opened on the top of the seat body 9a1. The top of one of the sliding seats 2a of the inner louver 11b is inserted into the slot 9a21.

[0036] The connecting seat 9b includes a seat plate 9b1 and a locking plate 9b2. The seat plate 9b1 is located above the upper belt body of the timing belt 12, and the locking plate 9b2 is located below the upper belt body of the timing belt 12 and is screwed and locked to the seat plate 9b1 by fasteners, thereby clamping the upper belt body of the timing belt 12. The seat plate 9b1 has a slot 9b11. The top of one of the sliding seats 2b of the connecting inner louver 11d is inserted into the slot 9b11. When each louver is flipped open and the timing belt 12 is driven to rotate, the sliding seat 2a of the connecting inner louver 11b is pulled towards the fixed seat. When the inner louver 11a1 moves, the sliding seat 2b connected to the inner louver 11d is pulled and moves towards the fixed seat 11c1, so that the sliding seat 2a connected to several sliding louvers 11e moves together towards the fixed seat 11a1, and the sliding seat 2a connected to several sliding louvers 11f moves together towards the fixed seat 11c1, thereby enabling the inner louver 11b and several sliding louvers 11e to be folded up at one end of the frame 1 along with the outer louver 11a, and the inner louver 11d and several sliding louvers 11f to be folded up at the other end of the frame 1 along with the outer louver 11c.

[0037] It is worth mentioning that the timing belt 12 used in this louvered awning can be either an open or closed belt. The solution described in this embodiment is a closed belt. If an open belt is used, then two locking plates 9a11 need to be installed at the bottom of the seat 9a1 of the connecting seat 9a. One plate presses one end of the timing belt 12 against the bottom of the seat 9a1, and the other plate presses the other end of the timing belt 12 against the bottom of the seat 9a1.

[0038] Each sliding seat 2a, each sliding seat 2b, the fixed seat, and the fixed seat 11c1 has a through hole 4 on its top outer wall along the horizontal direction. Each sliding seat 2a, each sliding seat 2b, the fixed seat, and the fixed seat 11c1 have a fixing hole 5 on its top along the vertical direction that connects to the through hole 4. Each sliding seat 2a and the fixed seat 11a1 are pre-connected by a steel wire 3a passing through each through hole 4. The steel wire 3a is then tightened by screws 6a corresponding to each other into the fixing holes 5 of each sliding seat 2a and the fixed seat 11a1. Similarly, each sliding seat 2b and the fixed seat 11c1 are pre-connected by a steel wire 3b passing through each through hole 4. The steel wire 3b is then tightened by screws 6b corresponding to each other into the fixing holes 5 of each sliding seat 2b and the fixed seat 11c1. With this setting, when the sliding seat 2a connecting the inner louver 11b and the sliding seat 2b connecting the inner louver 21d are pulled towards the middle of the frame 1, the remaining sliding seats 2a and 2b can gradually slide towards the middle of the frame 1 under the traction of the steel wire. This allows the inner louver 11b, several sliding louver 11e, inner louver 21d, and several sliding louver 21f to be spread out in the frame 1. It is worth mentioning that, in order to ensure the service life of the steel wire and reduce the noise generated by friction during operation, a layer of rubber can be vulcanized on the outside of the steel wire.

[0039] Each sliding seat 2a, each sliding seat 2b, fixed seat 11a1, and fixed seat 21c1 has a bearing 7 engaged in its middle. The rotating shafts at the ends of the inner louver 11b and several sliding louver 11e are engaged with the inner rings of the bearings 7 on each sliding seat 2a. The rotating shafts at the ends of the inner louver 11d and several sliding louver 11f are engaged with the inner rings of the bearings 7 on each sliding seat 2b. The rotating shaft at the end of the outer louver 11a is engaged with the inner ring of the bearing 7 on fixed seat 11a1. The rotating shaft at the end of the outer louver 11c is engaged with the inner ring of the bearing 7 on fixed seat 21c1.

[0040] Combination Figure 3 , Figure 10 , Figure 11 , Figure 12 , Figure 13 as well as Figure 14Inside the frame 1, a sliding connecting rod 18 is provided along the length direction outside the synchronous belt 12. Below the sliding groove, a push rod motor 17 is provided and hinged to the inner wall of the frame 1. The drive end of the push rod motor 17 is connected to a long strip-shaped push rod 171. Several reversing connecting rods 19, which are spaced apart and hinged to the inner wall of the frame 1, are fixed between the push rod 171 and the sliding connecting rod 18. A sliding groove 181 is provided along the length direction on the sliding connecting rod 1811. Several rolling wheels 1811 are rolled in the sliding groove 1811. Several swing arms 8 are provided between the synchronous belt 12 and the sliding connecting rod 18, which are spaced apart and have a connecting shaft 81 fixed at one end. The swing arms 8 are connected one-to-one with each sliding seat 2a, each sliding seat 2b, fixed seat 11a1, and fixed seat 11c through the connecting shaft 81. The inner ring of the upper bearing 7 is engaged, and the swing arm 8 and the rolling wheel 1811 are hinged. When the louvers are folded, the rolling wheel 1811 prevents interference caused by the presence of the swing arms 8. When the louvers need to be flipped open or closed, the push rod motor 17 drives the push rod 171 and each reversing link 19 to push the sliding link 18 to swing upward, so that the end of each swing arm 8 that is hinged to the rolling wheel 1811 rotates to a certain extent, and the end connected to the adapter shaft 81 drives the inner ring of the bearing 7 to rotate, and the inner ring of the bearing 7 drives the louvers to rotate, thereby completing the opening or closing action of each louver.
