Description

Technical Field

[0001] This utility model relates to the field of decorative mechanical flowers, and in particular to a mechanical flower device that dynamically folds and blooms. Background Technology

[0002] Mechanical flowers are decorative devices that combine mechanical transmission, electronic control, and materials to simulate dynamic effects such as blooming. They are commonly used in commercial backdrop displays, cultural tourism landscapes, and educational settings.

[0003] Chinese patent document CN219125478U discloses a dynamic folding and blooming mechanical flower device. It includes a base, a flower stand, and a drive mechanism. The flower stand is connected to the base via the drive mechanism. The base has a hexagonal structure. The drive mechanism includes a driving gear, a rotary motor, a driven gear, and a connecting rod. The rotating end of the rotary motor is connected to the driving gear with its rotating end facing upwards. The connecting rod is located on the six sides of the base and surrounds the driving gear. The central shaft of the driven gear is movably mounted on the upper end of the connecting rod, and the teeth of the driven gear mesh with the teeth of the driving gear. The flower stand includes a flower and leaf frame and a crank-connecting rod mechanism. The flower and leaf frame is located on the six sides of the base and is connected to the driven gear via the crank-connecting rod mechanism. The synchronous opening and closing of all mechanical petals is controlled through gear transmission and crank-connecting rod transmission. The transmission control is simple, and the mechanical flower unfolds gracefully and beautifully during the opening and closing process, making it suitable for environmental decoration and ecological simulation demonstrations.

[0004] Although the device described in the above literature can synchronously control the opening and closing of all mechanical petals, in actual use, the mechanical petals, as decorations, need to continuously open and close, which is not convenient for forming dynamic folding flowers. In addition, in order to maintain the aesthetics, the mechanical petals need to be maintained or replaced regularly, which is not convenient for disassembling and assembling the mechanical petals. Utility Model Content

[0005] The main purpose of this invention is to provide a mechanical flower device for dynamic folding and blooming, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A dynamic folding and blooming mechanical flower device includes a base plate and mechanical petals. A base is fixedly connected to the outer end of the lower surface of the base plate. The outer bottom end of the base plate has several mounting holes at equal angles. A drive motor is fixedly connected to the middle of the lower surface of the base plate. A rotating rod is fixedly connected to the output shaft of the drive motor. A connecting rod is rotatably connected to the middle of the upper surface of the rotating rod. A first limiting rod is fixedly connected to the outer end of the lower surface of the connecting rod. Several first placement slots are formed at equal angles on the upper surface of the base plate. A first support rod is rotatably connected to the lower surface of the outer end of the connecting rod. A first limiting rod is rotatably connected to the lower surface of the inner end of the first support rod. Two support rods are connected. A third support rod is rotatably connected to the upper outer surface of the first support rod, and a fourth support rod is rotatably connected to the upper outer surface of the second support rod. A second limiting rod is provided at the bottom of the connection between the first and second support rods. A connecting block is rotatably connected to the outer end of the connection between the third and fourth support rods. Mechanical petals are provided on the outer side of the connecting block. A second storage groove is opened in the middle of the inner side of the mechanical petals. Several fixed T-shaped rods are fixedly connected to the outer end of the upper surface of the base plate at equal angles by bolts.

[0015] Preferably, the support leg is fixedly connected to the upper surface of the base plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This device, through the design of rotating rods, connecting rods, and several support rods, enables mechanical petals to dynamically fold and bloom on the base plate. The drive motor, rotating rods, connecting rods, first support rod, second support rod, third support rod, and fourth support rod form a linkage mechanism, causing the mechanical petals connected to the junction of the third and fourth support rods to perform equal-angle extension and retraction movements. The bottom of the mechanical petals is limited to a certain point on the base plate by a fixed T-shaped rod. Several mechanical petals form a ring structure, and the above-mentioned linkage mechanism can form a dynamic folding and blooming effect.

[0018] 2. This device, through the designed connecting block, second storage slot and fixed T-shaped rod, allows the mechanical petals to be removed for maintenance or replacement. The connecting block, third support rod and fourth support rod are rotatably connected by the same shaft. The outer end of the connecting block is rotatably connected to the second storage slot opened on the inner side of the mechanical petal by the rod. The fixed T-shaped rod at the bottom of the mechanical petal is fixed to the base plate by several bolts. The shaft and bolts at the connection can be removed to facilitate the replacement of the petals. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1, as Figures 1-6 As shown, a mechanical flower device for dynamic folding and blooming has a base 2 fixedly connected to the outer end of the lower surface of the base plate 1, and a number of mounting holes 3 are opened at equal angles at the bottom outer end of the base 2.

[0029] As a decorative item, the mechanical flower needs to be installed on a background such as a wall. The mechanical flower can be fixed to the background wall by passing through the mounting holes 3 opened on the base 2 with a sturdy bolt. Since the drive motor 4 is installed on the lower surface of the base plate 1, a protective shell is set on the outside of the drive motor 4 to prevent damage to the drive motor 4 during installation.

[0030] A drive motor 4 is fixedly connected to the middle of the lower surface of the base plate 1. A rotating rod 5 is fixedly connected to the output shaft of the drive motor 4. A connecting rod 6 is rotatably connected to the middle of the upper surface of the rotating rod 5. A first limiting rod 7 is fixedly connected to the outer end of the lower surface of the connecting rod 6. Several first storage slots 8 are opened at equal angles on the upper surface of the base plate 1. The bottom of the first limiting rod 7 is slidably connected to the first storage slot 8. A first support rod 9 is rotatably connected to the lower surface of the outer end of the connecting rod 6. A second support rod 10 is rotatably connected to the lower surface of the inner end of the first support rod 9. A third support rod 11 is rotatably connected to the upper surface of the outer end of the first support rod 9. A fourth support rod 12 is rotatably connected to the upper surface of the outer end of the second support rod 10. The junction of the first support rod 9, the second support rod 10, the third support rod 11 and the fourth support rod 12 is rotatably connected by an "I" shaped rod. The outer end of the fourth support rod 12 is rotatably connected to the outer end of the third support rod 11.

[0031] A linkage mechanism is provided on the base plate 1. The output shaft of the drive motor 4 is fixedly connected to the inner end of the rotating rod 5. A connecting rod 6 is rotatably connected to the middle of the upper surface of the rotating rod 5. Since the lower surface of the outer end of the connecting rod 6 is restricted to one side by the first limiting rod 7, when the rotating rod 5 rotates, it moves laterally with one side of the connecting rod 6. The first limiting rod 7 slides in the first storage groove 8 opened on the base plate 1.

[0032] The first support rod 9, the second support rod 10, the third support rod 11, and the fourth support rod 12 are rotatably connected to each other to form a deformable quadrilateral frame. Several sets of frames formed by the first support rod 9, the second support rod 10, the third support rod 11, and the fourth support rod 12 are connected to each other according to the number of mechanical petals 15. The connection between the frames is that the connection between the first support rod 9 and the third support rod 11 is rotatably connected to the connection between the fourth support rod 12 and the second support rod 10, so that several sets of frames can be linked and deformed simultaneously. Each set of frames is provided with a second limiting rod 13 at the lower end of the connection between the first support rod 9 and the second support rod 10. The second limiting rod 13 slides in the first placement groove 8 and can limit the direction of deformation movement in the middle of each set of frames, so that the deformation state of each set of frames is consistent.

[0033] When the left end of connecting rod 6 overlaps with the inner end of rotating rod 5, rotating rod 5 and connecting rod 6 form the shortest distance. The right end of connecting rod 6 moves the inner end of the frame formed by the first support rod 9, the second support rod 10, the third support rod 11 and the fourth support rod 12 inward. At this time, the mechanical petals 15 connected to the frame are in a closed state. The output shaft of drive motor 4 drives rotating rod 5 to rotate clockwise. The length between rotating rod 5 and connecting rod 6 is lengthened, so that the frame with mechanical petals 15 gradually unfolds. When rotating rod 5 rotates to the right, the left end of connecting rod 6 overlaps with the outer end of rotating rod 5. Rotating rod 5 and connecting rod 6 form the longest distance. The lateral spacing in the middle of the frame is lengthened. At this time, mechanical petals 15 are in a fully open state.

[0034] A second limiting rod 13 is provided at the bottom of the connection between the first support rod 9 and the second support rod 10. The bottom of the second limiting rod 13 is slidably connected in the first storage groove 8. The top surface of the second limiting rod 13 is fixedly connected to the bottom surface of the "I"-shaped rod at the connection between the first support rod 9 and the second support rod 10. A top plate 18 is provided at the bottom inner side of the mechanical petal 15. Several legs 19 are fixedly connected at equal angles to the outer end of the lower surface of the top plate 18. The legs 19 are fixedly connected to the upper surface of the base plate 1.

[0035] When the frame formed by the first support rod 9, the second support rod 10, the third support rod 11 and the fourth support rod 12 is driven by the drive motor 4, the rotating rod 5 and the connecting rod 6 to perform the folding and flowering movement, the bottom of the mechanical petal 15 rotates with the fixed T-shaped rod 17 on the base plate 1. The fixed T-shaped rod 17 limits the bottom of the mechanical petal 15 to a fixed point. In conjunction with the frame formed by the first support rod 9, the second support rod 10, the third support rod 11 and the fourth support rod 12, the mechanical petal 15 completes the dynamic folding and flowering effect.

[0036] The inner side of the mechanical petal 15 is connected to the frame via a connecting block 14, and the bottom of the mechanical petal 15 is connected to the base plate 1 via a fixed T-shaped rod 17. When the mechanical petal 15 needs to be disassembled or assembled, it is only necessary to remove the shaft at the connection between the connecting block 14 and the frame and the fixing bolts of the fixed T-shaped rod 17.

[0037] Example 2, as Figure 3 , Figures 5-7 As shown, a connecting block 14 is rotatably connected to the outer end of the connection between the third support rod 11 and the fourth support rod 12. A mechanical petal 15 is provided on the outer side of the connecting block 14. A second storage groove 16 is opened in the middle of the inner side of the mechanical petal 15. The outer end of the connecting block 14 is rotatably connected to the second storage groove 16 by a rod. Several fixed T-shaped rods 17 are fixed at equal angles to the outer end of the upper surface of the base plate 1 by bolts. The top of the fixed T-shaped rod 17 is rotatably connected to the "T"-shaped groove opened in the middle of the bottom end of the mechanical petal 15.

[0038] The top plate 18 is installed inside the mechanical petal 15 to cover the rotating rod 5, connecting rod 6, first support rod 9, second support rod 10, third support rod 11 and fourth support rod 12, thereby improving the aesthetics.

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.
