Therefore, there is an urgent need for a driving folding wing swinging device that can utilize the heat to improve the overall practicality.

This technical solution has at least the following beneficial effects: the first piston is located in the cavity, dividing the interior of the cavity into an upper cavity and a lower cavity along the up and down directions, the whole can be placed at the position of an external heat source, and the bottom surface of the base is close to the heat source, the heat is transferred upward to the lower cavity, so that the air in the lower cavity expands, thereby pushing the first piston upward, the driving rod located on the first piston swings, and drives the driving rod to transfer power upward to the swing mechanism, so that the first flapping wing in the swing mechanism swings upward, and after consuming the heat energy in the lower cavity, the first piston moves downward and resets under the action of gravity, and the driving member provides a reset driving force to the swing mechanism, so that the first flapping wing in the swing mechanism swings and resets, so that the whole can be placed at the heat source position as a decorative piece, and the heat is used as a driving force to drive the first flapping wing to swing up and down, and there is no need to install a separate driving source, which is more energy-saving and environmentally friendly when used, and improves the overall interest and practicality.

As a further improvement of the above technical solution, the swing mechanism includes a linkage shaft, a flapping shaft, a four-bar mechanism, a first connecting rod, a second connecting rod, a third connecting rod and a transmission rod, the linkage shaft is rotatably connected to the bracket, the flapping shaft is movably connected to the bracket along the up and down directions, the upper end of the four-bar mechanism is rotatably connected to one end of the flapping shaft, the lower end of the four-bar mechanism is rotatably connected to one end of the linkage shaft, the other end of the linkage shaft is connected to a driven wheel, one end of the first connecting rod is eccentrically rotatably connected to the driven wheel, the other end of the first connecting rod, one end of the second connecting rod and one end of the third connecting rod are respectively rotatably connected to the other end of the flapping shaft, a first flapping wing is rotatably connected between the left end of the four-bar mechanism and the other end of the second connecting rod, a first flapping wing is rotatably connected between the right end of the four-bar mechanism and the other end of the third connecting rod, the two first flapping wings and the flapping shaft are rotatably connected with the transmission rod, and the drive rod is transmission-connected to the driven wheel. The driving rod moves up and down to transmit power to the driven wheel. Since the first connecting rod is eccentrically rotated and connected to the driven wheel, the height of the first connecting rod changes with the rotation of the driven wheel, which can drive the flapping shaft connected to the first connecting rod to move up and down. Since a four-bar mechanism is connected between the end of the flapping shaft and the end of the linkage shaft, the four-bar mechanism can be driven to fold downward or extend upward as the flapping shaft moves up and down. Since a transmission rod is provided between the two first flapping wings and the flapping shaft for limited traction, the first flapping wing between the four-bar mechanism and the second connecting rod and the third connecting rod can be swung up and down as the left and right ends of the four-bar mechanism are driven.

As a further improvement of the above technical solution, the swing mechanism also includes a connecting shaft, a first transmission block, a first driven rod and a transmission wheel.

The transmission wheel is connected to one end of the connecting shaft, and the transmission wheel is meshed with the driven wheel for transmission. When the driving shaft moves up and down, power can be transmitted to the first transmission block through the first driven rod rotatably connected thereto. Since the first driven rod and the transmission block are eccentrically connected, the transmission block can be driven by the first driven rod to rotate around the connecting shaft, and the transmission wheel on the connecting shaft can transmit power to the driven wheel through mutual meshing with the driven wheel, so that the driving shaft drives the driven wheel to rotate back and forth when it moves up and down.

As a further improvement of the above technical solution, the connecting shaft is connected with a second transmission block, the base is connected with a cylinder sleeve, the cylinder sleeve is connected with a second piston, the second transmission block is eccentrically connected with a second driven rod, and the bottom end of the second driven rod is rotatably connected to the second piston. When the connecting shaft rotates, it can drive the second transmission block connected to its outer side to rotate. Since the second transmission rod and the second transmission block are eccentrically connected, with the reciprocating rotation of the second transmission block, the second transmission rod can drive the second piston to move up and down in the cylinder sleeve. The movement limitation of the second piston and the second cylinder sleeve is used to further improve the stability of the connecting shaft when rotating.

As a further improvement of the above technical solution, the swing mechanism also includes a second flapping wing, and the second flapping wing is rotatably connected to the side of the two first flapping wings that are away from each other, and a fourth connecting rod is rotatably connected between the rotation connection between the first transmission block and the first driven rod, and the rotation connection between the second transmission block and the second driven rod, and the two second flapping wings. A fourth connecting rod is also rotatably connected to the rotation connection between the first transmission block and the first driven rod, and similarly, another fourth connecting rod is also rotatably connected to the rotation connection between the second transmission block and the second driven rod. Since the two fourth connecting rods are eccentrically connected to the first transmission block and the second transmission block, respectively, as the first transmission block and the second transmission block rotate, the two first flapping wings can be driven to swing through the two fourth connecting rods, respectively, so that the action of bionic flapping wings can be realized, which has the effect of imitating the flapping wings of a folded-wing bird.

By using the transmission wheel with a smaller outer diameter to transmit power to the driven wheel with a larger outer diameter, the power can be decelerated, the output speed can be reduced, and the output torque can be increased, thereby achieving more efficient energy conversion and motion control.

As a further improvement of the above technical solution, the bracket is formed with two slots spaced apart in the horizontal direction, the two slots extend in the up-down direction, and the two ends of the flapping shaft pass through the two slots respectively. The two ends of the flapping shaft are limited by the two slots on the bracket, and the first connecting rod and the four-bar mechanism provide support for the two ends of the flapping shaft, so as to realize the up-and-down movement of the flapping shaft.

As a further improvement of the above technical solution, the end of the flapping shaft is connected to a decorative piece. The decorative piece is connected to the flapping shaft and cooperates with the swinging of the first flapping wings on both sides to further improve the overall appearance.

1 and 2, a heat-utilizing folding-wing swinging device includes a cylinder mechanism, a bracket 200 and a swinging mechanism, wherein the cylinder mechanism is used to utilize heat to drive the swinging mechanism to work. Specifically, the cylinder mechanism includes a base 110 and a first piston 120, wherein a cavity is provided in the base 110, wherein the first piston 120 is located in the cavity, wherein the first piston 120 is connected to a driving rod 121 which passes upward through the base 110, and in actual application, a sliding connection is formed between the first piston 120 and the base 110 at a position where the first piston 120 passes upward through the base 110, thereby improving the stability of the up and down movement of the first piston 120; the bracket 200 is connected to the top side of the base 110; the swinging mechanism is arranged on the bracket 200, wherein the swinging mechanism has a first flapping wing 310 which can swing up and down, and the swinging mechanism is in transmission connection with the driving rod 121, wherein the driving rod 121 can drive the first flapping wing 310 to swing up and down.

As can be seen from the above, the first piston 120 is located in the cavity, and the interior of the cavity is divided into an upper cavity and a lower cavity along the up and down directions. The whole can be placed at the position of an external heat source, and the bottom surface of the base 110 is close to the heat source. The heat is transferred upward to the lower cavity, causing the air in the lower cavity to expand, thereby pushing the first piston 120 upward, and the driving rod 121 located on the first piston 120 swings, driving the driving rod 121 to transfer power to the swing mechanism upward, so that the first flapping wing 310 in the swing mechanism swings upward. After consuming the heat energy in the lower cavity, the first piston 120 moves downward and resets under the action of gravity, and the driving member provides a reset driving force for the swing mechanism, so that the first flapping wing 310 in the swing mechanism swings and resets. In this way, the whole can be placed at the heat source position as a decorative piece, and heat is used as a driving force to drive the first flapping wing 310 to swing up and down. There is no need to install a separate driving source. It is more energy-saving and environmentally friendly when used, and the overall interest and practicality are improved.

The swing mechanism is mainly used to drive the first flapping wing 310 to move. For example, it can be a crank rocker mechanism. The drive shaft and the first flapping wing 310 are respectively connected to the crank rocker transmission. The drive shaft transmits power to the first flapping wing 310 through the crank rocker mechanism, thereby driving the first flapping wing 310 to swing up and down. In order to achieve symmetrical swinging of the two first flapping wings 310, in this embodiment, the swing mechanism includes a linkage shaft 320, a flapping shaft 330, a four-bar mechanism 340, a first connecting rod 350, a second connecting rod 360, a third connecting rod 370 and a transmission rod 380, wherein:

A linkage shaft 320, the linkage shaft 320 is rotatably connected to the bracket 200, the rotation axis of the linkage shaft 320 extends in the left-right direction, one end of the linkage shaft 320 can extend out of the bracket 200, and a driven wheel 390 is connected to the end position of the linkage shaft 320 extending out of the bracket 200, and the driving rod 121 is drivingly connected to the driven wheel 390;

A flapping shaft 330, wherein the flapping shaft 330 is movably connected to the bracket 200 in the up-down direction. In practical applications, two parts slidably connected to the ends of the flapping shaft 330 may be formed on the bracket 200, thereby improving the stability of the up-down movement of the flapping shaft 330;

The four-rod mechanism 340 includes a first rod body, a second rod body, a third rod body and a fourth rod body. The bottom end of the first rod body is connected to the bottom end of the second rod body by relative rotation along an axis extending in the front-to-back direction. The top end of the third rod body is connected to the top end of the fourth rod body by relative rotation along an axis extending in the front-to-back direction. The bottom end of the third rod body is connected to the top end of the first rod body by relative rotation along an axis extending in the front-to-back direction. The bottom end of the fourth rod body is connected to the top end of the second rod body by relative rotation along an axis extending in the front-to-back direction. The upper end of the four-rod mechanism 340 is connected to one end of the flapping shaft 330, that is, the top end of the third rod body and the top end of the fourth rod body are connected to the flapping shaft 330 by relative rotation. The lower end of the four-rod mechanism 340 is connected to the linkage One end of the shaft 320, that is, the bottom end of the first rod body and the bottom end of the second rod body are rotatably connected to the linkage shaft 320, the rotation connection point between the top end of the first link 350 and the bottom end of the third link 370 is the left end of the four-bar mechanism 340, and the rotation connection point between the top end of the second link 360 and the bottom end of the fourth link 470 is the right end of the four-bar mechanism 340. A first flapping wing 310 is rotatably connected between the left end of the four-bar mechanism 340 and the end of the second link 360, and the rotation axis of the first flapping wing 310 extends in the front-to-back direction. A first flapping wing 310 is rotatably connected between the right end of the four-bar mechanism 340 and the end of the third link 370, and the rotation axis of the first flapping wing 310 also extends in the front-to-back direction.

A first connecting rod 350, one end of which is eccentrically connected to the driven wheel 390, and the connection between the first connecting rod 350 and the driven wheel 390 is a rotational connection, and the other end of the first connecting rod 350, one end of the second connecting rod 360 and one end of the third connecting rod 370 are respectively rotationally connected to the end of the flapping shaft 330 away from the four-bar mechanism 340;

The transmission rod 380 is rotatably connected between the two first flapping wings 310 and the flapping shaft 330. One end of the transmission rod 380 can form a first connecting ring, which is sleeved on the outside of the flapping shaft 330 to achieve rotational connection between one end of the transmission rod 380 and the flapping shaft 330. The other end of the flapping shaft 330 can also form a second connecting ring. A side rod is provided on the side of the first flapping wing 310 away from the flapping shaft 330. The second connecting ring is sleeved on the outside of the side rod to achieve rotational connection between the transmission rod 380 and the first flapping wing 310. The same is true for the connection of the two first flapping wings 310.

In this swing mechanism, the driving rod 121 moves up and down to transmit power to the driven wheel 390. Since the first connecting rod 350 is eccentrically connected to the driven wheel 390, as the driven wheel 390 rotates, the height of the first connecting rod 350 changes, which can drive the flapping shaft 330 connected to the first connecting rod 350 to move up and down. Since a four-bar mechanism 340 is connected between the end of the flapping shaft 330 and the end of the linkage shaft 320, as the flapping shaft 330 moves up and down, the four-bar mechanism 340 can be driven to fold downward or extend upward. Since there is a transmission rod 380 between the two first flapping wings 310 and the flapping shaft 330 for limited traction, as the left and right ends of the four-bar mechanism 340 are driven, the first flapping wing 310 between the four-bar mechanism 340 and the second connecting rod 360 and the third connecting rod 370 can be swung up and down.

In order to drive the driven wheel 390 to rotate with the driving force of the driving rod 121 moving up and down, the driving rod 121 can be directly rotatably connected to the driven wheel 390 through a rod body. In order to improve the stability of the transmission, in the present embodiment, the swing mechanism also includes a connecting shaft 400, a first transmission block 410, a first driven rod 420 and a transmission wheel 430. The connecting shaft 400 is rotatably connected to the bracket 200. The connecting shaft 400 is located below the linkage shaft 320. The rotation axis of the connecting shaft 400 extends in the front-to-back direction. The first transmission block 410 is connected to the connecting shaft 400. The first driven rod 420 is connected to the first transmission block 410. One end of the first driven rod 420 is eccentrically connected to the first transmission block 410, that is, the position where the first driven rod 420 is connected to the first transmission block 410 is not colinear with the connecting shaft 400, and the end of the first driven rod 420 is rotatably connected to the first transmission block 410, the other end of the first driven rod 420 is rotatably connected to the top of the driving rod 121, and the rotation axes of both ends of the first driven rod 420 extend in the front-to-back direction, the transmission wheel 430 is connected to one end of the connecting shaft 400, the outer periphery of the transmission wheel 430 is a toothed structure, the outer periphery of the driven wheel 390 is a toothed structure, and the transmission wheel 430 and the driven wheel 390 are meshed with each other for transmission. When the driving shaft moves up and down, the power can be transmitted to the first transmission block 410 through the first driven rod 420 rotatably connected thereto. Since the first driven rod 420 and the transmission block are eccentrically connected, the transmission block can be driven by the first driven rod 420 to rotate around the connecting shaft 400, and the transmission wheel 430 on the connecting shaft 400 is meshed with the driven wheel 390 to transmit the power to the driven wheel 390, thereby realizing the reciprocating rotation of the driven wheel 390 driven by the driving shaft when it moves up and down.

Furthermore, the connecting shaft 400 is connected with a second transmission block 440, the base 110 is connected with a cylinder sleeve 450, a second piston is connected in the cylinder sleeve 450, the second transmission block 440 is eccentrically connected with a second driven rod 480, and the connection between the second transmission rod 380 and the second transmission block 440 is a rotational connection, the rotation axis of the second transmission rod 380 extends in the front-to-back direction, the bottom end of the second driven rod 480 is rotationally connected to the second piston, and the rotation axis of the second driven rod 480 extends in the front-to-back direction. When the connecting shaft 400 rotates, it can drive the second transmission block 440 connected to its outer side to rotate. Since the second transmission rod 380 and the second transmission block 440 are eccentrically connected, as the second transmission block 440 reciprocates, the second transmission rod 380 can drive the second piston to move up and down in the cylinder sleeve 450, and the stability of the connecting shaft 400 when rotating is further improved by using the activity limitation of the second piston and the second cylinder sleeve 450.

In actual application, in order to increase the swinging range of the first driven rod 420 and the second driven rod 480, the connecting shaft 400 can be disconnected at the rotational connection between the first driven rod 420 and the second driven rod 480, and the disconnected position is connected to each other through the two first transmission blocks 410 and the two second transmission blocks 440. At this time, the end of the first driven rod 420 is rotationally connected between the two first transmission blocks 410, and the end of the second driven rod 480 is rotationally connected between the two second transmission blocks 440.

In the above embodiment, two single-piece first folding wings are formed in the swing mechanism and swing up and down, while in the present embodiment, the swing mechanism further includes a second flapping wing 460, and the two first flapping wings 310 are respectively rotatably connected to the sides away from each other with the second flapping wings 460, and the rotation axes of the two second flapping wings 460 extend in the front-to-back direction, and the rotation connection between the first transmission block 410 and the first driven rod 420 and the rotation connection between the second transmission block 440 and the second driven rod 480 are respectively connected to the rotation connection between the two second flapping wings 460. A fourth connecting rod 470 is connected. In actual application, a rotating shaft is formed at the connection between the first transmission block 410 and the first driven rod 420. A fourth connecting rod 470 is rotatably connected between the rotating shaft and the second flapping wing 460. The rotation axes at both ends of the fourth connecting rod 470 extend along the front-to-back direction. Similarly, another rotating shaft is formed at the connection between the second transmission block 440 and the second driven rod 480. Another fourth connecting rod 470 is rotatably connected between the rotating shaft and another second flapping wing 460. The rotation axes at both ends of this fourth connecting rod 470 also extend along the front-to-back direction.

In this embodiment in which the first folding wing and the second folding wing are symmetrically formed on both sides, a fourth connecting rod 470 is also rotatably connected to the rotational connection between the first transmission block 410 and the first driven rod 420. Similarly, another fourth connecting rod 470 is also rotatably connected to the rotational connection between the second transmission block 440 and the second driven rod 480. Since the two fourth connecting rods 470 are eccentrically connected to the first transmission block 410 and the second transmission block 440, respectively, as the first transmission block 410 and the second transmission block 440 rotate, the two first flapping wings 310 can be driven to swing respectively through the two fourth connecting rods 470, thereby realizing the bionic flapping action, which has the effect of imitating the flapping of a folded-wing bird.

In order to better drive the first flapping wing 310 and the second flapping wing 460 to swing, in this embodiment, the outer diameter of the transmission wheel 430 is smaller than the outer diameter of the driven wheel 390. By using the transmission wheel 430 with a smaller outer diameter to transmit power to the driven wheel 390 with a larger outer diameter, the power can be decelerated, the output speed can be reduced, and the output torque can be increased, thereby achieving more efficient energy conversion and motion control.

The two ends of the flapping shaft 330 are slidably connected to the bracket 200 along the up and down directions. There are many structural forms. Slide blocks are respectively set at the two end positions of the flapping shaft 330, and slide grooves are set at the positions corresponding to the two slide blocks on the bracket 200. The sliding connection between the flapping shaft 330 and the bracket 200 is achieved through the cooperation of the slide blocks and the slide grooves. In this embodiment, two slots 210 spaced apart in the horizontal direction are formed on the bracket 200. The two slots 210 extend along the up and down directions. The two ends of the flapping shaft 330 pass through the two slots 210 respectively. In actual applications, in order to further improve the stability of the flapping shaft 330 relative to the up and down movement in the slots 210, a protrusion and a groove structure can also be set between the outer side of the flapping shaft 330 and the inner side wall of the slot 210, so that the two can cooperate with each other more closely. The two ends of the flapping shaft 330 are limited by the two slots 210 on the bracket 200, and the first connecting rod 350 and the four-bar mechanism 340 provide support for the two ends of the flapping shaft 330, so as to realize the up and down movement of the flapping shaft 330.

In some embodiments, the end of the flapping shaft 330 is connected with a decorative piece 331, and the decorative piece 331 can be connected to one end of the flapping shaft 330, or the decorative piece 331 can be connected to both ends of the flapping shaft 330. The decorative piece 331 is connected to the flapping shaft 330, and cooperates with the swing of the first flapping wings 310 on both sides to further improve the overall appearance. In practical applications, the connection between the decorative piece 331 and the flapping shaft 330 is a detachable connection, and the decorative piece 331 can be fixed to the end of the flapping shaft 330 by a buckle and a slot that cooperate with each other, or it can be further fixed to the end of the flapping shaft 330 by driving a screw or other connecting piece.

The base 110 is mainly used to form a cavity for gas expansion to drive the first piston 120. As shown in FIG3, in this embodiment, the base 110 includes a top plate 111, a bottom plate 112, and a cylinder 113 connected between the top plate 111 and the bottom plate 112. The cylinder 113 is surrounded by the cavity, the drive rod 121 passes through the top plate 111 upward, and the bracket 200 is connected to the top side of the top plate 111. The base 110 is mainly composed of three parts: the top plate 111, the bottom plate 112 and the cylinder 113. When assembling, it is only necessary to put the first piston 120 into the cylinder 113, and cover the upper and lower ends of the cylinder 113 with the top plate 111 and the bottom plate 112 to block the upper and lower ends of the cavity. The overall structure is simple.

The cylinder body 113 and the bottom plate 112 may be an integrally formed structure, and then the top plate 111 is connected to the top side of the cylinder body 113, so as to form a cavity in the cylinder body 113. Alternatively, the cylinder body 113 and the bottom plate 112 may be an integrally formed structure, and then the bottom plate 112 is connected to the bottom side of the cylinder body 113. In this embodiment, the top plate 111 and the bottom plate 112 are detachably connected. At this time, the outer diameter of the cylinder body 113 is smaller than the outer diameters of the top plate 111 and the bottom plate 112. The top plate 111 and the bottom plate 112 are directly connected and fixed, and a bolt can be driven into the part of the top plate 111 outside the cylinder body 113, and a nut is connected after the bolt passes through the bottom plate 112, and the nut is threadedly connected to the bolt, and the nut is pressed against the bottom plate 112, so that the top plate 111 and the bottom plate 112 are tightened in the up and down direction, and a nut and a bolt form a connection group, and a plurality of connection groups can be arranged at intervals around the cylinder body 113, so that the top plate 111 and the bottom plate 112 firmly press the cylinder body 113 up and down. The top plate 111 and the bottom plate 112 are connected to each other, and the cylinder body 113 is clamped between the top plate 111 and the bottom plate 112. When the internal structure needs to be maintained, the top plate 111 and the bottom plate 112 are separated from each other, and the overall internal structure of the base 110 can be exposed, which is conducive to improving the convenience of later use and maintenance. In practical applications, an upper annular groove may be provided on the bottom side of the top plate 111, and a lower annular groove may be provided on the top side of the bottom plate 112. The top end of the cylinder body 113 is inserted into the upper annular groove, and the bottom end of the cylinder body 113 is inserted into the lower annular groove, so that the top plate 111, the bottom plate 112 and the cylinder body 113 can be conveniently positioned relative to each other. Sealing rings may also be installed in the upper annular groove and the lower annular groove. The upper and lower ends of the cylinder body 113 are respectively connected to the top plate 111 and the bottom plate 112 through sealing rings, so as to improve the sealing of the cavity.

The concept of the present invention can be applied to a wide range of scenarios. For example, when making tea, the steam generated by the freshly boiled tea can be cleverly used to drive the folded-wing bird ornament to flap its wings. This design not only actively releases the fragrance of tea through the movement of the first flapping wing 310 and the second flapping wing 460, but also cools the temperature of the tea, providing a unique and interesting tea ceremony experience. In addition, when the device returns, the first flapping wing 310 and the second flapping wing 460 are brought back to their original state by the action of gravity, so that the entire device can autonomously complete the next cycle, cleverly combining thermal energy and gravitational potential energy to achieve efficient use of energy.

The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
