Description

Technical Field

[0001] This invention relates to a track-assisted swing. Background Technology

[0002] Currently, children's swings on the market are large and have bulky frames, making them inconvenient for home use. They are usually placed in outdoor children's play areas. In addition, the seats of commercially available children's swings are usually low, requiring caregivers to frequently bend over and exert force to help children use the swing, both of which are unfriendly to caregivers. Summary of the Invention

[0003] The purpose of this invention is to provide an improved swing that occupies little space, is easy to use indoors, and is caregiver-friendly, making it worry-free and effortless.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A track-type swing, the track-type swing comprising: Base The seat assembly can reciprocate within the base; An assist mechanism is provided on the base. After the seat assembly moves to a position that cooperates with the assist mechanism, the assist mechanism pushes the seat assembly to accelerate.

[0005] In this invention, reciprocating motion can be the up-and-down reciprocating motion of a pendulum, or reciprocating motion within a plane. The cooperation between the seat assembly and the assist mechanism means that the two can interact, and this interaction allows the assist mechanism to propel the seat assembly to accelerate. There are no major limitations on the method of cooperation, such as frictional contact, but this invention is not limited to frictional contact.

[0006] In some embodiments, the assist mechanism includes a drive wheel and a motor that drives the drive wheel to rotate. When the seat assembly passes the drive wheel, the drive wheel makes frictional contact with the seat assembly, and the drive wheel applies an external force to the seat assembly to accelerate the movement of the seat assembly.

[0007] In some embodiments, the base is provided with an arc-shaped track, and the seat assembly can perform a pendulum motion along the track. The drive wheel is disposed on the track and located in the middle region of the seat assembly's movement path, or the drive wheel is disposed at at least one of the two ends of the seat assembly's movement path. The drive wheel can be disposed in the middle region of the seat assembly's movement path or at the ends of the movement path, as long as it can propel the seat assembly to accelerate. When disposed at the ends, it can be disposed at one end or at both ends. In this invention, the middle region refers to the region excluding the two ends.

[0008] In some embodiments, the drive wheel is located in the middle region of the movement path of the seat assembly and has a first use state of forward rotation and a second use state of reverse rotation; The assist mechanism also includes a control component that controls the rotation and direction of the drive wheel, so that the drive wheel accelerates the seat assembly. The control component can independently control the starting and stopping of the drive wheel's rotation, independently change the direction of rotation of the drive wheel, or simultaneously control both changes.

[0009] In some embodiments, the assist mechanism further includes a position detection unit for detecting whether the seat assembly has moved into position, the position detection unit being electrically connected to the control component. Moving into position means that the seat assembly has moved to a position that mates with the assist mechanism. After the position detection unit is electrically connected to the control component, the control component can adjust the rotation and direction of the drive wheel based on the position of the position detection unit.

[0010] In some embodiments, the assist mechanism further includes a sensing unit disposed on the seat assembly. The sensing unit is configured to activate the position detection unit and control the rotation and direction of the drive wheel through the control component. The sensing unit and the position detection unit cooperate to detect the position of the seat assembly. When its position moves to a position that aligns with the assist mechanism, the control component can adjust the rotation and direction of the drive wheel.

[0011] In some embodiments, the control component is also electrically connected to the motor, and controls the rotation and direction of the drive wheel by controlling the rotation and direction of the motor. In some embodiments, the bottom of the seat assembly includes two transition surfaces and a working surface disposed between the two transition surfaces. The height of each part of the working surface from the track is approximately equal, and the two transition surfaces are respectively inclined outward and upward from the working surface.

[0012] In some embodiments, the sensing unit is a magnet, and the position detection unit is a Hall sensor.

[0013] In some embodiments, when the seat assembly reaches the first position, the sensing unit activates the position detection unit and changes the rotation direction of the drive wheel through the control component.

[0014] In some embodiments, when the seat assembly reaches the first position, the sensing unit activates the position detection unit and controls the drive wheel to rotate in the opposite direction via the control component; when the seat assembly leaves the first position, the control component controls the drive wheel to stop rotating.

[0015] In some embodiments, the position detection unit includes a first position detection unit and a second position detection unit; when the seat assembly reaches a first position, the sensing unit activates the first position detection unit and changes the rotation direction of the drive wheel through the control component; when the seat assembly reaches a second position, the sensing unit activates the second position detection unit and changes the rotation direction of the drive wheel again through the control component.

[0016] In some embodiments, the sensing unit includes a first sensing unit and a second sensing unit, and the position detection unit includes a first position detection unit and a second position detection unit; when the seat assembly reaches a first position, the first sensing unit activates the first position detection unit and changes the rotation direction of the drive wheel through the control component; when the seat assembly reaches a second position, the second sensing unit activates the second position detection unit and changes the rotation direction of the drive wheel again through the control component.

[0017] In some embodiments, the position detection unit is fixedly mounted on the track, and the sensing unit is fixedly mounted at the bottom of the seat assembly.

[0018] In some embodiments, the assist mechanism further includes a transmission wheel fixedly connected to the output shaft of the motor, the transmission wheel being connected to the drive wheel via a transmission belt.

[0019] In some embodiments, the assist mechanism further includes an elastic element disposed between the drive wheel and the base, the elastic force of the elastic element causing the drive wheel to make frictional contact with the seat assembly.

[0020] In some embodiments, when the seat assembly moves from the first end to the second end of the track, the drive wheel makes frictional contact with one of the transition surfaces and causes the elastic element to deform until the drive wheel makes frictional contact with the working surface, at which point the deformation of the elastic element remains essentially unchanged; subsequently, the drive wheel begins to make frictional contact with another of the transition surfaces and gradually moves outward, at which point the elastic deformation of the elastic element gradually returns to its initial state.

[0021] In some embodiments, the drive wheel and transmission wheel are fixedly disposed in the drive housing; the track swing also includes a support frame fixedly disposed on the base, the support frame having a cavity for accommodating the drive housing, the lower end of the elastic element contacting the bottom of the cavity, and the upper end of the elastic element fixedly disposed on the outer bottom of the drive housing.

[0022] In some embodiments, the base is provided with a first hanging rod and a second hanging rod, and the support frame has a first hook portion and a second hook portion, the first hook portion being hung on the first hanging rod and the second hook portion being hung on the second hanging rod.

[0023] In some embodiments, the base also includes legs for supporting the track.

[0024] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The track-type swing of the present invention occupies little space and is convenient for indoor use; and it has an assist mechanism, so the seat component can move back and forth on the track by itself without the caregiver having to push it, thus being caregiver-friendly and saving them time and effort.

Detailed Implementation

[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0029] The invention can be further understood through the specific embodiments given below, but they are not intended to limit the invention.

[0030] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments. In the following embodiments, it should be noted that the terms "upper," "lower," "inner," and "outer" are based on the orientation observed by the child while seated on the swing's seat assembly. For example, see the attached drawing. Figure 1 In Chinese, the term "internal" refers to... Figure 1 The middle part, in the term "outer" refers to Figure 1 The directions on the left and right sides are not specified. Therefore, the orientations and positional relationships described in this invention are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, only have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] like Figure 1-23 As shown, this embodiment provides a track-type swing.

[0032] Specifically, such as Figure 1-2 As shown in 10-11 and 17-18, the track swing includes a base 1, a seat assembly 3 and an assist mechanism 5. The seat assembly 3 can reciprocate on the base 1. The assist mechanism 5 is set on the base, and after the seat assembly 3 moves to a position that cooperates with the assist mechanism 5, the assist mechanism 5 pushes the seat assembly 3 to accelerate.

[0033] A track 2 is provided on the base 1, and the seat assembly 3 is equipped with wheels 4 that are adapted to the track 2. The wheels 4 move on the track 2. An assist mechanism 5 is fixedly mounted on the base 1 and is used to drive the seat assembly 3 to reciprocate along the track 2. The reciprocating movement of the seat assembly 3 along the track 2 thus realizes the swing's movement. Because of the use of the assist mechanism 5, and because the assist mechanism 5 can drive the seat assembly 3 to reciprocate, this swing does not require additional assistance from the caregiver of the infant or toddler, making it worry-free and effortless for the caregiver.

[0034] The seat assembly 3 is used for passengers of the track-type swing, such as infants and toddlers. To ensure the safety of infants and toddlers, a safety belt or similar device can be installed in the seat assembly 3. The number of wheels 4 in the seat assembly 3 is not particularly limited; four are shown in the figure, but this invention is not limited to this. Reciprocating motion refers to movement back and forth between at least two points. The amplitude of the reciprocating motion can be adjusted, as long as the reciprocating motion continues on the track 2. The amplitude can be adjusted by the assist mechanism 5. The reciprocating motion can be the up-and-down reciprocating motion of a pendulum, or it can be reciprocating motion within a plane. The path of the reciprocating motion is related to the characteristics of the track. The assist mechanism 5 includes a drive wheel 6 and a motor that drives the drive wheel 6 to rotate. When the seat assembly 3 passes the drive wheel 6, the drive wheel 6 abuts against and rubs against the seat assembly 3, so that the drive wheel 6 applies an external force to the seat assembly 3, causing the seat assembly 3 to accelerate. The drive wheel 6 applies an external force to the seat assembly 3, and this external force has at least one component moving left or right along the track 2, causing the seat assembly 3 to accelerate to the left or right. The drive wheel 6 can be directly fixedly connected to the output shaft of the motor, or it can be... Figure 2-4 As shown, a transmission wheel 14 is further installed in the assist mechanism 5. This transmission wheel 14 is fixedly connected to the output shaft of the motor, and the transmission wheel 14 is connected to the drive wheel 6 via a transmission belt 15. Figure 3-4 As shown, an elastic element 16 can also be provided between the drive wheel 6 and the base 1. The elastic force of the elastic element 16 allows the drive wheel 6 to abut against the seat assembly 3 and make frictional contact with it. By providing the elastic element 16, the movement of the seat assembly 3 on the track 2, especially the movement of the part abutting against the drive wheel 6, can be made more gentle, preventing excessive impact force when the seat assembly 3 moves from both sides to the middle, thus ensuring the comfort and safety of the passenger.

[0035] The shape of track 2 is not particularly limited. In some embodiments, track 2 can be arc-shaped, and the seat assembly 3 can move in a pendulum motion along track 2. The drive wheel 6 is located in the middle region of track 2, for example, it can be located at the lowest point of the arc-shaped track 2. When located at the lowest point, the drive wheel 6 is most effective in changing the direction of the applied external force. Track 2 can be two parallel arc-shaped tracks as shown in the figure, or it can be other shapes, such as rings. The drive wheel 6 can, for example, change the direction of the applied external force by changing its rotation direction.

[0036] Preferably, such as Figure 2As shown, the bottom of the seat assembly 3 includes two transition surfaces 24 and a working surface 25 disposed between the two transition surfaces 24. The height of each part of the working surface 25 from the track 2 is approximately equal. The two transition surfaces 24 are respectively inclined outward and upward from the working surface 25. That is, the central area of ​​the bottom of the seat assembly 3 has a similar degree of curvature to the track 2, while the two side areas are more inclined outward. On the working surface 25, the drive wheel 6 is always in close contact with the bottom of the seat assembly 3, so that the drive wheel 6 provides the maximum and most effective external force to the seat assembly 3. The transition surface 24 is set to be more inclined outward, which can reduce the degree of contact between the seat assembly 3 and the drive wheel 6, which is conducive to the seat assembly 3 continuing to move outward, that is, to the left or right. And when the seat assembly 3 moves from the left or right side of the track 2 towards the middle, it is conducive to slowly contacting the drive wheel 6. When the seat assembly 3 moves from the first end (e.g., left end) to the second end (e.g., right end) of the track 2, the drive wheel 6 abuts against a transition surface 24, causing the elastic element 16 to deform until the drive wheel 6 abuts against the working surface 25. At this point, the deformation of the elastic element 16 remains essentially unchanged. Subsequently, the drive wheel 6 begins to abut against another transition surface 24 and gradually moves outward, at which point the elastic deformation of the elastic element 16 gradually returns to its initial state. The cooperation of the transition surface 24, the working surface 25, and the elastic element 16 makes the seat assembly 3 more comfortable and safer to operate. The elastic element 16 can be a conventional type of elastic element, such as a spring.

[0037] The assist mechanism 5 also includes a control component 9, which controls the rotation and direction of the drive wheel 6, i.e., controls the start and stop of the drive wheel 6, or controls its rotation direction, so that the drive wheel 6 accelerates the seat assembly 3. The seat assembly 3 reciprocates on the track 2. When the direction of movement of the seat assembly 3 changes, for example, when the seat assembly 3 moves from left to right, the drive wheel 6 rotates to the right to accelerate the movement of the seat assembly 3. After the seat assembly 3 moves to its highest point on the right, it falls back to the left. During the continued movement to the left, the control component controls the drive wheel 6 to turn to the left, so that the seat assembly 3 is accelerated when it moves to the left.

[0038] Furthermore, the assist mechanism 5 includes a position detection unit 7 mounted on the base 1, a sensing unit 8 mounted on the seat assembly 3, and a control component 9 electrically connected to the position detection unit 7. The control component 9 is also electrically connected to a motor. The sensing unit 8 is configured to activate the position detection unit 7 and change the rotation direction of the drive wheel 6 through the control component 9. The position detection unit 7 can detect the position of the sensing unit 8 on the seat assembly 3, that is, it can detect the position of the seat assembly 3 when the seat assembly 3 is reciprocating. Once the position detection unit 7 detects the sensing unit 8, the control component 9 controls the change of the rotation direction of the drive wheel 6, thereby accelerating the seat assembly 3 in different motion directions. The position detection unit 7 and the sensing unit 8 can be various sensors and sensed objects, such as Hall sensors and magnets, that is, a magnet can be set on the seat assembly 3 and a Hall sensor can be set on the base 1. Preferably, a magnet is set at the bottom of the seat assembly 3 and a Hall sensor is set on or near the track 2 of the base 1. Both can be fixed by adhesive tape, or pressed onto the bottom of the seat assembly 3 or the track 2, or by using magnets with screw holes to directly fix them to the bottom of the seat assembly 3 with screws. The height difference between the bottom of the seat assembly 3 and the track 2 is not particularly limited, as long as the drive wheel 6 can abut against the bottom of the seat assembly 3 and generate frictional contact. The height difference can be adjusted according to the size of the drive wheel 6 and the sensing force of the position detection unit 7 and the sensing unit 8. Figure 2 , 11 As shown in Figure 18, the control component 9 can be connected to an external power supply.

[0039] There are no particular limitations on the number and position of the sensing unit 8 and the position detection unit 7. For example, there can be one, two, or more sensing units 8, and one, two, or more position detection units 7, and the number of each does not necessarily need to be the same. For example, the position detection unit 7 can be fixedly installed on the track 2, and the sensing unit 8 can be fixedly installed at the bottom of the seat assembly 3. There are no particular limitations on the specific positions of the position detection unit 7 on the track 2 and the sensing unit 8 at the bottom of the seat assembly 3. For example, the position detection unit 7 can be located in the middle of the track 2, or on the left or right side of the track 2, and the sensing unit 8 can be located in the middle of the bottom of the seat assembly 3, or on the left or right side of the bottom of the seat assembly 3. The requirement is that the assist mechanism 5 can promptly change the rotation direction of the drive wheel 6 through the control component 9 when the two sense each other, thereby accelerating the movement of the seat assembly 3.

[0040] Regarding the specific configuration of the sensing unit 8 and the position detection unit 7, three specific methods are listed below, but the present invention is not limited to these three specific methods.

[0041] First setup method: See [link] Figure 1-9 A position detection unit 7 is installed in the middle of track 2, and a sensing unit 8 is installed in the middle of the bottom of seat assembly 3. When seat assembly 3 reaches the first position, i.e., when drive wheel 6 and working surface 25 of bottom of seat assembly 3 come into contact and frictional contact occurs, sensing unit 8 activates position detection unit 7 and changes the running state of drive wheel 6 through control component 9. The running state can include, for example, rotation direction, on and off; that is, control component 9 can control the change of rotation direction of drive wheel 6, or control the on and off rotation of drive wheel 6. Specifically, the movement process of seat assembly 3 and the working mode of drive wheel 6 are as follows: like Figure 5 As shown, when the seat assembly 3 is stationary, its bottom is located at the lowest point in the middle of the track 2. At this time, the drive wheel 6 abuts against the working surface 25 at the bottom of the seat assembly 3. The drive wheel 6 is connected to the drive wheel 14 via a transmission belt 15, for example, a belt. The elastic element 16 is compressed to its maximum deformation. At this time, the sensing unit 8 on the seat assembly 3 and the position detection unit 7 on the track 2 are aligned. At this time, the control component 9 controls the drive wheel 6 to rotate in one direction, for example, to the left. Driven by the drive wheel 6, the seat assembly 3 also begins to move to the left. The contact part between the drive wheel 6 and the seat assembly 3 transitions from the working surface 25 to the transition surface 24 on the right. During this process, the elastic element 16 slowly rebounds, and the seat assembly 3 continues to move to the left. Figure 6 As shown, when the seat assembly 3 moves to the point where the drive wheel 6 disengages from the bottom of the seat assembly 3, the drive wheel 6 no longer provides power to the seat assembly 3, and the control component 9 controls the drive wheel 6 to stop driving and rotating. The seat assembly 3, relying on its own inertia, will continue to move a distance to the left. Through specific settings of the control component 9, such as the drive power, it can be adjusted so that the highest point reached by the seat assembly 3 in its leftward movement remains on the track 2, meaning the seat assembly 3 will not deviate from the track 2 and cause safety issues. Furthermore, the drive power can be set to one, two, or more levels; different levels result in different highest points that the seat assembly 3 can reach on the left, to meet the experience needs of different passengers. After reaching the highest point on the left, the seat assembly 3, due to its own gravity, turns to move to the right. Figure 7 As shown, the seat assembly 3 moves from left to right under its own weight. The drive wheel 6 gradually contacts the bottom of the seat assembly, transitioning from the right transition surface 24 to the middle working surface 25. During this process, the assist mechanism 5 is gradually pressed down, and the elastic element 16, such as a spring, is gradually compressed. The spring makes the drive wheel 6 fit more closely to the bottom of the seat assembly, providing the drive wheel 6 with greater friction and driving force for the seat assembly 3. Figure 5As shown, when the seat assembly 3 moves from left to right to the middle state, i.e., when the drive wheel 6 abuts against the working surface 25 at the bottom of the seat assembly 3 and generates frictional contact, the elastic element 16 in the assist mechanism 5 remains in the maximum compression state, and the drive wheel 6 continues to drive the seat assembly with maximum friction. At this time, the position detection unit 7 on the track 2 senses the sensing unit 8 on the seat assembly 3, the sensing unit 8 activates the position detection unit 7, the position detection unit 7 sends a signal to the control component 9, and the control component 9 controls the drive wheel 6 to start driving and change the rotation direction to right rotation, driving the seat assembly 3 to continue moving to the right. Figure 8 As shown, during the movement of the seat assembly 3 from the middle state to the right, the drive wheel 6 gradually moves away from the bottom of the seat assembly. The part of the drive wheel 6 that abuts against the seat assembly 3 first gradually transitions to the left transition surface 24, and then moves away from the bottom of the seat assembly. During this process, the assist mechanism 5 floats up, the elastic element 16 rebounds, and the drive wheel 6 leaves the bottom of the seat assembly. The drive wheel 6 no longer provides friction and power to the seat assembly 3. During this process, the drive wheel 6 rotates continuously to the right, providing power for the rightward movement of the seat assembly 3. When the drive wheel 6 leaves the bottom of the seat assembly 3, the control component 9 controls the drive wheel 6 to stop rotating. Figure 9 As shown, after the drive wheel 6 stops rotating and driving, the swing's seat assembly 3 continues to move to the right due to its own inertia until it reaches its highest point on the right side, after which it begins to fall freely to the left due to gravity. When the seat assembly 3 moves to the middle position on the left, the sensing unit 8 triggers the position detection unit 7, and the control component 9 controls the rotation of the drive wheel 6 to restart, rotating it in the opposite direction, i.e., to the left. The entire swing reciprocates in the process described above.

[0042] Second setup method: See [link] Figure 10-16 A position detection unit is installed on both the left and right sides of track 2, and a sensing unit 8 is installed in the middle of the bottom of the seat assembly 3. The position detection unit on the left is called the first position detection unit 10, and the position detection unit on the right is called the second position detection unit 11. When the seat assembly 3 reaches the first position, the sensing unit 8 activates the first position detection unit 10 and changes the rotation direction of the drive wheel 6 through the control component 9; when the seat assembly 3 reaches the second position, the sensing unit 8 activates the second position detection unit 11 and changes the rotation direction of the drive wheel 6 again through the control component 9. Specifically, the movement process of the seat assembly 3 and the working mode of the drive wheel 6 are as follows: like Figure 12As shown, when the seat assembly 3 is stationary, its bottom is located at the lowest point in the middle of the track 2. At this time, the drive wheel 6 abuts against the working surface 25 at the bottom of the seat assembly 3. The drive wheel 6 is connected to the drive wheel 14 via a transmission belt 15, for example, a belt. The elastic element 16 is compressed to its maximum deformation. At this time, the control component 9 controls the drive wheel 6 to rotate in one direction, for example, to the left. Under the drive of the drive wheel 6, the seat assembly 3 also begins to move to the left. The contact part between the drive wheel 6 and the seat assembly 3 transitions from the working surface 25 to the transition surface 24 on the right. During this process, the elastic element 16 slowly rebounds, and the seat assembly 3 continues to move to the left. Figure 13 As shown, when the seat assembly 3 moves to the left and the first position detection unit 10 on the left side senses the sensing unit 8, the sensing unit 8 triggers the first position detection unit 10, and the control component 9 controls the drive wheel 6 to change its rotation direction, that is, to rotate to the right. The seat assembly 3, due to its own inertia, will continue to move to the left for a certain distance. After reaching the highest point on the left, the seat assembly 3, due to its own gravity, will turn to move to the right. Figure 14 As shown, the seat assembly 3 moves from left to right. The drive wheel 6 gradually contacts the bottom of the seat assembly, transitioning from the right transition surface 24 to the middle working surface 25. During this process, the assist mechanism 5 is gradually pressed down, and the elastic element 16, such as a spring, is gradually compressed. The spring causes the drive wheel 6 to fit more closely to the bottom of the seat assembly, providing the drive wheel 6 with greater friction and driving force for the seat assembly 3. Figure 15 As shown, when the seat assembly 3 moves from left to right to the middle state, i.e., when the drive wheel 6 abuts against the working surface 25 at the bottom of the seat assembly 3, the elastic element 16 in the power assist mechanism 5 remains in the maximum compression state, and the drive wheel 6 continues to drive the seat assembly with maximum friction. At this time, the drive wheel 6 still rotates to the right. Figure 16 As shown, during the movement of the seat assembly 3 from the middle position to the right, the drive wheel 6 gradually moves away from the bottom of the seat assembly. The part of the drive wheel 6 that abuts against the seat assembly 3 first gradually transitions to the left transition surface 24, and then moves away from the bottom of the seat assembly. During this process, the assist mechanism 5 floats up, and the elastic element 16 rebounds. When the seat assembly 3 moves to the right and the second position detection unit 11 on the right side senses the sensing unit 8, the sensing unit 8 triggers the second position detection unit 11. The control component 9 controls the drive wheel 6 to change its rotation direction, that is, to rotate to the left. The swing's seat assembly 3 continues to move to the right due to its own inertia until it reaches the highest point on the right side, after which it begins to fall freely to the left due to gravity. The seat assembly 3 moves to the middle position on the left and continues to move to the left. During this process, the drive wheel 6 always rotates to the left until the first position detection unit 10 on the left senses the sensing unit 8. At this time, the control component 9 controls the drive wheel 6 to change its rotation direction to the right. The entire swing reciprocates in the process described above.

[0043] The third setup method: See [link / details] Figure 17-23A position detection unit is installed on both the left and right sides of track 2, and a sensing unit is installed on both the left and right sides of the bottom of seat assembly 3. The left-side position detection unit is called the first position detection unit 10, and the right-side position detection unit is called the second position detection unit 11. The left-side sensing unit is called the first sensing unit 12, and the right-side sensing unit is called the second sensing unit 13. When seat assembly 3 reaches the first position, the first sensing unit 12 activates the first position detection unit 10 and changes the rotation direction of drive wheel 6 through control component 9; when seat assembly 3 reaches the second position, the second sensing unit 13 activates the second position detection unit 11 and changes the rotation direction of drive wheel 6 again through control component 9. Specifically, the movement process of seat assembly 3 and the working mode of drive wheel 6 are as follows: like Figure 19 As shown, when the seat assembly 3 is stationary, its bottom is located at the lowest point in the middle of the track 2. At this time, the drive wheel 6 abuts against the working surface 25 of the bottom of the seat assembly 3. The drive wheel 6 is connected to the drive wheel 14 via a transmission belt 15, for example, a belt. The elastic element 16 is compressed to its maximum deformation position. The first sensing unit 12 and the second sensing unit 13 on the seat assembly 3 are located between the first position detection unit 10 and the second position detection unit 11 on the track 2. At this time, the control component 9 controls the drive wheel 6 to rotate in one direction, for example, to the left. Under the drive of the drive wheel 6, the seat assembly 3 also begins to move to the left. The contact part between the drive wheel 6 and the seat assembly 3 transitions from the working surface 25 to the transition surface 24 on the right. During this process, the elastic element 16 slowly rebounds, and the seat assembly 3 continues to move to the left. Figure 20 As shown, when the seat assembly 3 moves to the left and the first position detection unit 10 on the left side senses the first sensing unit 12 on the left side, the first sensing unit 12 triggers the first position detection unit 10, and the control component 9 controls the drive wheel 6 to change its rotation direction, that is, to rotate to the right. The seat assembly 3, due to its own inertia, will continue to move to the left for a certain distance. After reaching the highest point on the left, the seat assembly 3, due to its own gravity, will turn to move to the right. Figure 21 As shown, the seat assembly 3 moves from left to right. The drive wheel 6 gradually contacts the bottom of the seat assembly, transitioning from the right transition surface 24 to the middle working surface 25. During this process, the assist mechanism 5 is gradually pressed down, and the elastic element 16, such as a spring, is gradually compressed. The spring causes the drive wheel 6 to fit more closely to the bottom of the seat assembly, providing the drive wheel 6 with greater friction and driving force for the seat assembly 3. Figure 22 As shown, when the seat assembly 3 moves from left to right to the middle state, i.e., when the drive wheel 6 abuts against the working surface 25 at the bottom of the seat assembly 3, the elastic element 16 in the power assist mechanism 5 remains in the maximum compression state, and the drive wheel 6 continues to drive the seat assembly with maximum friction. At this time, the drive wheel 6 still rotates to the right. Figure 23As shown, during the movement of the seat assembly 3 from the middle position to the right, the drive wheel 6 gradually moves away from the bottom of the seat assembly. The part of the drive wheel 6 that abuts against the seat assembly 3 first gradually transitions to the left transition surface 24, and then moves away from the bottom of the seat assembly. During this process, the assist mechanism 5 floats up, and the elastic element 16 rebounds. When the seat assembly 3 moves to the right and the second position detection unit 11 on the right side senses the second sensing unit 13 on the right side, the second sensing unit 13 triggers the second position detection unit 11, and the control component 9 controls the drive wheel 6 to change its rotation direction, that is, to rotate to the left. The swing's seat assembly 3 continues to move to the right due to its own inertia until it reaches the highest point on the right side, and then begins to fall freely to the left due to gravity. The seat assembly 3 moves to the middle position on the left and continues to move to the left. During this process, the drive wheel 6 always rotates to the left until the first position detection unit 10 on the left side senses the first sensing unit 12 on the left side. At this time, the control component 9 controls the drive wheel 6 to change its rotation direction to the right. The entire swing reciprocates in the process described above.

[0044] Of course, the examples given above, which illustrate the three configurations, use the example of drive wheel 6 moving to the left first. However, this does not mean that the direction in which drive wheel 6 begins to move is limited in this invention. Drive wheel 6 can begin to move either to the left or to the right.

[0045] Regarding the fixed connection between the drive wheel 6 and the base 1, such as Figure 3-4 As shown, the drive wheel 6 and transmission wheel 14 are fixedly mounted in the drive housing 17. The track 2 swing also includes a support frame 18 fixedly mounted on the base 1. The support frame 18 has a cavity for accommodating the drive housing 17. The lower end of the elastic member 16 contacts the bottom of the cavity, and the upper end of the elastic member 16 is fixedly mounted on the outer bottom of the drive housing 17. For example, a groove can be provided on the outer bottom of the drive housing 17, and the upper end of the elastic member 16 can be engaged in the groove to fix the upper end of the elastic member 16. The base 1 is provided with a first hanging rod 19 and a second hanging rod 20. The support frame 18 has a first hook portion 21 and a second hook portion 22. The first hook portion 21 is hung on the first hanging rod 19, and the second hook portion 22 is hung on the second hanging rod 20, thereby fixing the support frame 18 on the base 1. The drive housing 17 can move up and down with the elastic member 16, thereby allowing the drive wheel 6 to move up and down accordingly.
