Detailed Description
The embodiment of the invention provides a swinging device which is used for realizing a swinging effect at low cost.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
An embodiment of the present invention provides a swing device, where fig. 1 to 4 are schematic structural diagrams of a swing device, and fig. 5 to 8 are schematic structural diagrams of another swing device.
Referring to fig. 1 and 5, the swing device according to the embodiment of the present invention includes a seat 14, a frame 1, a carriage 2, a first link 5, and a second link 6.
The seat part 14 is used for being placed on a supporting surface, and the support 1 is fixedly connected with the seat part 14. The support surface supports the swing device by the seat 14. Wherein the support surface may be the ground.
The carriage mechanism 2 is connected to the frame 1 by a first connecting member 5 and a second connecting member 6, respectively. Specifically, the first link member 5 is connected to the carriage 2 and the carriage 1, respectively, and the second link member 6 is connected to the carriage 2 and the carriage 1, respectively. The carriage mechanism 2 is suspended by the first link member 5 and the second link member 6.
The carriage mechanism 2 is swingable about a first swing position 19 and a second swing position 20, respectively, the first swing position 19 being located on the first link member 5, the second swing position 20 being located on the second link member 6, and the first swing position 19 being located above the second swing position 20.
The carrying mechanism 2 is provided with a carrying position for carrying the user 7. For example, an infant may be placed on the carrying position so that the infant can be swung by the carrying mechanism 2.
The first swing position 19 is closer to the loading position than the second swing position 20 in the horizontal direction. And a target line segment inclined to the support surface, the target line segment being a line segment connecting the first swing position 19 and the second swing position 20. At this time, the target line segment is not perpendicular to the support surface, and the first swing position 19 is closer to the loading position than the second swing position 20 in the horizontal direction, so that when the user 7 is loaded on the loading position, the first swing position 19 is closer to the center of gravity of the combination of the loading mechanism 2 and the user 7 than the second swing position 20 in the horizontal direction.
When the user 7 is in the loading position, the loading mechanism 2 and the user 7 form a center of gravity, which can be referred to as the load center of gravity. When the loading mechanism 2 swings around the first swing position 19 and the second swing position 20, respectively, the center of gravity of the load also swings around the first swing position 19 and the second swing position 20. At this time, the first swing position 19 and the second swing position 20 are rotation centers, respectively, and the distances from the first swing position 19 and the second swing position 20 to the center of gravity of the load are two rotation radii. Because the target line segment is inclined to the supporting surface, the two rotating radiuses are different in length, so that the center of gravity of the load can generate displacement in the vertical direction, and further gravitational potential energy difference can be generated, the gravitational potential energy difference can promote the carrying mechanism 2 to swing, and therefore the swinging device of the embodiment of the invention has the advantage that the swinging device is lower in cost compared with a scheme using a motor.
It should be understood that the above description has been made using the center of gravity of the load, and that the center of gravity of the loading mechanism 2 can also swing about the first swing position 19 and the second swing position 20 when the user 7 is not in the loading position.
In the embodiment of the present invention, the carrying mechanism 2 can be implemented in various ways, such as a seat-like structure.
In one particular implementation, as shown in fig. 1, 3, 5, and 7, the ride 2 includes a ride surface 3 and a frame structure 4. Wherein the frame structure 4 surrounds the passenger surface 3, the edges of the passenger surface 3 being connected to the frame structure 4, so that the frame structure 4 supports the passenger surface 3.
The first connecting part 5 and the second connecting part 6 are connected to the frame structure 4. The carrying position is arranged on the carrying surface 3, and the carrying surface 3 is of a flexible structure, so that the user 7 can feel comfortable when the user 7 is positioned at the carrying position.
In a specific implementation, the frame structure 4 may be a relatively rigid material such as metal or plastic. The riding surface 3 may be a plastic film or the like.
In the embodiment of the present invention, the seat 14 can be realized in various ways, for example, the seat 14 has a plate-like or block-like structure.
In one particular implementation, as shown in fig. 1, 3, 5 and 7, the seat 14 includes a first support bar 15, a second support bar 16, and a third support bar 17. One end of the second support bar 16 is fixedly connected with the first support bar 15, and the other end of the second support bar 16 is fixedly connected with the third support bar 17. The first support bar 15, the second support bar 16, and the third support bar 17 form a U-shaped structure. The second support bar 16 is fixedly connected with the bracket 1, for example, the middle part of the second support bar 16 is fixedly connected with the bracket 1. With the structure, the consumable material can be reduced, and the seat part 14 can also realize stable supporting effect.
In the present embodiment, the target line segment connecting the first swing position 19 and the second swing position 20 is inclined to the supporting surface, in other words, a target angle is formed between the target line segment and the supporting surface, and the target angle affects the swing speed of the carriage 2, specifically, the larger the target angle is, the larger the swing speed of the carriage 2 is. Therefore, the embodiment of the invention can adjust the swing speed of the carrying mechanism 2 by adjusting the target included angle.
There are various ways to adjust the target angle, such as adjusting the first swing position 19 and the second swing position 20 in the horizontal direction, or adjusting the first swing position 19 and the second swing position 20 in the vertical direction, so as to change the angle between the target line segment and the supporting surface, and thus adjust the swing speed of the loading mechanism 2.
For example, the second connecting member 6 includes a length adjusting mechanism. The second pivot position 20 is located between the length adjustment mechanism and the carrier mechanism 2. The length adjustment mechanism is used to adjust the length of the second link member 6 to adjust the position of the second swing position 20.
The length adjusting mechanism can be implemented in various ways, for example, the length adjusting mechanism is two threaded rods, one of the threaded rods is connected with the carrying mechanism 2, and the other threaded rod is connected with the bracket 1, so that the second swing position 20 can move along with one threaded rod by relatively rotating the two threaded rods, thereby changing the angle of the target included angle formed between the target line segment and the supporting surface. In other examples, the length adjustment mechanism may be in the form of a linear module, wherein the slider and the main body of the linear module are connected to the frame 1 and the carriage mechanism 2, respectively.
In the embodiment of the present invention, there are various implementations of the first connecting part 5 and the second connecting part 6, for example, the first connecting part 5 and the second connecting part 6 are a rigid connecting structure, and may be a ball bearing in particular; alternatively, the first and second connection parts 5 and 6 may be a flexible connection structure, for example, a structure including a steel wire, a nylon cord, an elastic member, or the like.
In a specific implementation, the first connecting part 5 includes a first extension spring 12, one end of the first extension spring 12 is connected to the carriage 2, and the other end of the first extension spring 12 is connected to the bracket 1. The second link member 6 includes a second extension spring 13, one end of the second extension spring 13 is connected to the carriage mechanism 2, and the other end of the second extension spring 13 is connected to the carriage 1. In this way, the carriage mechanism 2 is connected to the bracket 1 through the first tension spring 12 and the second tension spring 13, respectively, so that the carriage mechanism 2 can be buffered to a certain extent, and the carriage mechanism 2 has a good swinging effect.
In the embodiment of the present invention, optionally, as shown in fig. 2 and 6, the first connection part 5 is located above the second connection part 6.
The connection position of the first link member 5 and the bracket 1 is higher than the connection position of the first link member 5 and the carriage mechanism 2. Thus, under the influence of gravity at the loading mechanism 2, the first link member 5 generates a pulling force on the bracket 1, which is directed to the outside of the bracket 1, so that the first link member 5 suspends the loading mechanism 2.
The connecting position of the second connecting member 6 and the carriage 2 is higher than the connecting position of the second connecting member 6 and the carriage 1. Thus, under the influence of gravity at the carrier mechanism 2, the second link member 6 generates a pushing force on the carriage 1, which is directed toward the carriage 1, so that the second link member 6 supports the carrier mechanism 2.
Since the first pivoting position 19 is located on the first connecting part 5, the first pivoting position 19 produces a pulling force on the side facing the stand 1; since the second pivot position 20 is located on the second link member 6, the second pivot position 20 generates a pushing force on the side facing the stand 1. The weight of the carrier 2, the pulling force at the first swing position 19, and the pushing force at the second swing position 20 are balanced. When the carriage mechanism 2 swings, the first swing position 19 and the second swing position 20 are rotation centers, respectively.
There are various specific implementations of the first connecting member 5 and the second connecting member 6, and two examples thereof will be described below.
Example one:
as shown in fig. 1, 2, 3, and 4, in the swing device of the present example, one end of the first link member 5 is connected to the bracket 1, and the other end of the first link member 5 is connected to the carriage mechanism 2. The first connecting component 5 is a strip structure, and two ends of the first connecting component are respectively connected to the bracket 1 and the carrying mechanism 2. In this case, the first connecting member 5 may be a nylon rope, a steel wire, a steel rope, or the like. In the example of fig. 1 and 2, the first connecting member 5 includes a first tension spring 12 and a fixing member 23, one end of the first tension spring 12 is connected to the fixing member 23, the other end of the first tension spring 12 is connected to the middle portion of the frame structure 4 of the carriage mechanism 2, and one end of the fixing member 23 remote from the first tension spring 12 is fixedly connected to the bracket 1. At this time, the first swing position 19 is located at a connecting position of the first tension spring 12 and the fixing member 23, that is, an end of the first tension spring 12 away from the carriage mechanism 2 is the first swing position 19.
On the other hand, the second connecting member 6 includes a first branch 8, a second branch 9, and a third branch 10. One end of the first branch member 8, one end of the second branch member 9 and one end of the third branch member 10 are fixedly connected to each other at a fixed connection position. One end of the first branch member 8 far away from the fixed connection position is connected with the carrying mechanism 2, one end of the second branch member 9 far away from the fixed connection position is connected with the carrying mechanism 2, and one end of the third branch member 10 far away from the fixed connection position is connected with the bracket 1. The second pivot position 20 is then located at the end of the third branch 10 remote from the fixed connection position.
Further, the second connecting part 6 further includes a second extension spring 13, as shown in fig. 2, one end of the second extension spring 13 is connected to the third branch 10, and the other end of the second extension spring 13 is connected to the bracket 1, in other words, the third branch 10 is connected to the bracket 1 through the second extension spring 13, and at this time, the second swing position 20 is located at the connecting position of the second extension spring 13 and the bracket 1.
The first link member 5 is positioned above the second link member 6, and the position of connection between the first link member 5 and the carriage 1 is higher than the position of connection between the first link member 5 and the carriage 2. The connecting position of the second connecting member 6 and the carriage 2 is higher than the connecting position of the second connecting member 6 and the carriage 1. Alternatively, in order to orient the loading position of the loading mechanism 2 to the outside of the rack 1, as shown in fig. 1 and 2, the connection position of the first connection member 5 and the loading mechanism 2 is closer to the rack 1 than the connection position of the second connection member 6 and the loading mechanism 2 in the horizontal direction.
Example two:
as shown in fig. 5, 6, 7, and 8, in the swing device of the present example, the first connection member 5 has a Y-shaped structure, in which the first connection member 5 includes a first end portion, a second end portion, and a third end portion. The first end and the second end are connected to the carriage 2, and the third end is connected to the carriage 1. Specifically, the first connecting member 5 may be a nylon rope, a metal rod, or the like. In the example shown in fig. 5, the first link member 5 and the bracket 1 are connected to each other in a string-like configuration, and the first link member 5 and the carriage mechanism 2 are connected to each other in a U-shaped metal rod configuration. Wherein the first swing position 19 is located at the position where the first connecting part 5 and the bracket 1 are connected.
On the other hand, one end of the second link member 6 is connected to the carriage mechanism 2, and the other end of the second link member 6 is connected to the carriage 1. The second connecting member 6 may be a tension spring or the like, and in the example shown in fig. 5, the second connecting member 6 includes a ball bearing and a rotating shaft, the rotating shaft is sleeved on an inner ring of the ball bearing, an outer ring of the ball bearing is fixedly connected with the carriage 2, at this time, the second swing position 20 is located at the ball bearing, and the carriage 2 swings around an axis of the ball bearing.
The connection position of the first link member 5 and the carriage 2 is farther from the bracket 1 than the connection position of the second link member 6 and the carriage 2 in the horizontal direction. And, since the first link member 5 is located above the second link member 6, the position of connection of the first link member 5 and the carriage 1 is higher than the position of connection of the first link member 5 and the carriage 2, and the position of connection of the second link member 6 and the carriage 2 is higher than the position of connection of the second link member 6 and the carriage 1, so that the carriage position on the carriage 2 faces the carriage 1.
Optionally, the bracket 1 is provided with a plurality of clamping positions 11 arranged along the horizontal direction, and the third end of the first connecting part 5 is clamped with one of the plurality of clamping positions 11. When necessary, the third end can be moved into engagement with the other engagement locations 11, so that the first swing position 19 can be adjusted, and thus the target angle formed between the target line segment and the support surface, to adjust the swing speed of the loading mechanism 2. There are various specific implementations of the card slot 11, for example, the card slot 11 is a U-shaped card slot. The third end of the first connecting member 5 may be a bump.
The swing device of the embodiment of the invention can be particularly a rocking chair or a rocking bed for infants. I.e. the baby is placed at the loading position.
The swing device of the embodiment of the invention utilizes a suspension type arrangement mode, the time period of physical swing can be improved, and the carrying mechanism 2 can swing around the first swing position 19 and the second swing position 20 respectively, and the first swing position 19 is closer to the carrying position than the second swing position 20 along the horizontal direction. The target line segment connecting the first swing position 19 and the second swing position 20 is inclined to the support surface, so that the swing speed and the swing time period of the carrier 2 can be controlled by adjusting the target angle formed between the target line segment and the support surface. By realizing such an effect by means of a physical structure, the cost can be reduced.
In some devices using a simple pendulum, as shown in fig. 9, the target center of gravity 18 at the loading mechanism 2 swings along a first trajectory 21, and at this time, the potential energy difference between the highest position and the lowest position of the target center of gravity 18 at the loading mechanism 2 is large, which results in a large swing speed of the loading mechanism 2, and is not favorable for giving a comfortable experience to the user 7 sitting on the loading position. However, the swing device according to the embodiment of the present invention utilizes the gravitational potential energy difference of the center of gravity of the carriage mechanism 2 to swing, and since the carriage mechanism 2 can swing around the first swing position 19 and the second swing position 20, respectively, at this time, as shown in fig. 10, the target center of gravity 18 at the carriage mechanism 2 swings along the second trajectory 22, the swing device according to the embodiment of the present invention can reduce the gravitational potential energy difference between the highest position and the lowest position of the target center of gravity 18 at the carriage mechanism 2 during swinging, so that the swing speed is slow, no power is required, the time for the carriage mechanism 2 to swing can be increased, and a comfortable swing experience can be provided to the user 7.
As described above, the swing device according to the embodiment of the present invention includes the seat 14, the frame 1, the carriage mechanism 2, the first link member 5, and the second link member 6. The seat 14 is intended to rest on a support surface to support the oscillating device. The frame 1 and the seat 14 are fixedly connected, and the carriage 2 is connected to the frame 1 by the first link member 5 and the second link member 6, respectively. The carriage mechanism 2 is swingable about a first swing position 19 and a second swing position 20, respectively, the first swing position 19 being located on the first link member 5, and the second swing position 20 being located on the second link member 6. The carrying mechanism 2 is provided with a carrying position for carrying the user 7. In this way, the user 7 can swing on the carriage 2 with the carriage 2. Since the first swing position 19 is closer to the loading position than the second swing position 20 in the horizontal direction, and the first swing position 19 is located above the second swing position 20, the target line segment is inclined to the supporting surface, and the target line segment is a line segment connecting the first swing position 19 and the second swing position 20. Therefore, when the carriage mechanism 2 swings around the first swing position 19 and the second swing position 20, the first swing position 19 and the second swing position 20 are respectively rotation centers, and the distances from the first swing position 19 to the center of gravity of the carriage mechanism 2 and the distances from the second swing position 20 to the center of gravity of the carriage mechanism 2 are respectively two rotation radii, and the two rotation radii are different in distance, so that the center of gravity of the carriage mechanism 2 generates a displacement amount in the vertical direction, a gravitational potential energy difference is formed, the carriage mechanism 2 swings, and compared with the swing generated by a motor, the swing device of the embodiment of the invention can realize the swing at low cost.
