The rocking chair is an important tool for taking care of babies. It can temporarily replace the parents' hands to hold the baby and relieve the parents' fatigue. During use, the baby can be placed in the position on the rocking chair. In order to improve the movement function of the rocking chair in the related art, this application proposes a rocking chair movement device.

The application of a rocking chair motion device to a rocking chair is used as an example for explanation.

As shown in Figures 1 to 4, and Figures 9 to 15, in some embodiments, the rocking chair movement device includes a base 1000, a mounting base 2000, and a first driving mechanism 3000.

The base 1000 serves as the foundation of the entire rocking chair and plays a major supporting role to prevent the rocking chair from tipping when it is placed on the ground. For example, four legs 1200 are provided on the base 1000, and the legs 1200 are designed to tilt outward. In this way, when the base 1000 is placed on the ground, the four legs 1200 can effectively support the stability of the base 1000, thus ensuring the stability of the entire rocking chair. Prevent the rocking chair from tipping over during movement. The base 1000 is provided with an arc-shaped guide rail 1100. The arc-shaped guide rail 1100 will be used to guide the movement of the mounting base 2000. The arc-shaped guide rail 1100 can be set inside the base 1000 or outside the base 1000, from the perspective of safety and aesthetics. From the angle of view, it is better to arrange the arc-shaped guide rail 1100 in the base 1000.

The mounting base 2000 is provided on the base 1000. For example, it can be provided inside the base 1000 or outside the base 1000. From the perspectives of safety, aesthetics, etc., it is better to set the mounting base 2000 within the base 1000. The mounting base 2000 mainly plays the role of carrying the rocking chair frame 5000 and driving the movement of the rocking chair frame 5000. For example, the rocking chair includes a rocking chair frame 5000, and the rocking chair frame 5000 is provided with a placement position. This placement position is a structure for the baby to sit/lie down, for example, by The mesh bag is fixed on the rocking chair frame 5000 to form a placement position, and a structure such as a basket can also be provided on the rocking chair frame 5000 to form a placement position. It can be understood that when the mounting base 2000 is disposed in the base 1000, the base 1000 is provided with corresponding slots. 1320, for connection between the rocking chair frame 5000 and the mounting base 2000, which will be explained in detail below.

The mounting base 2000 is supported on the arc-shaped guide rail 1100 so that it can move along the extension direction of the arc-shaped guide rail 1100. The power of the mounting base 2000 comes from the first driving mechanism 3000. The first driving mechanism 3000 can be a motor or a cylinder. As a power device, the first driving mechanism 3000 operates to exert a force on the mounting base 2000. The mounting base 2000 can move along the arc-shaped guide rail 1100 under force, thereby driving the rocking chair frame 5000 to move, so that the rocking chair The frame 5000 forms a visual effect of swinging back and forth.

Since the guide rail is arc-shaped, when the mounting base 2000 moves from the highest point to the lowest point of the arc-shaped guide rail 1100, or from the lowest point to the highest point of the arc-shaped guide rail 1100, the mounting base 2000 can change in a certain angle, so that The synchronous drive rocking chair frame 5000 exhibits a certain angle change, and when the mounting base 2000 switches between the lowest point and the highest point of the arc guide rail 1100, the height of the mounting base 2000 also changes to a certain extent. Between the angle change and Altitude changes work together to increase fun and comfort.

The first driving mechanism 3000 can be fixed to the base 1000 to drive the mounting base 2000. The first driving mechanism 3000 and the mounting base 2000 can be driven directly or indirectly. Since the first driving mechanism 3000 and the base 1000 are relatively fixed, the first driving mechanism 3000 and the mounting base 2000 are relatively fixed. When a driving mechanism 3000 operates, it can drive the mounting base 2000 to move along the arc-shaped guide rail 1100.

It is also possible that the first driving mechanism 3000 is fixed to the mounting base 2000 to act on the base 1000. In this way, the first driving mechanism 3000 and the mounting base 2000 are combined into a whole body and cannot change their positions relative to each other. The first driving mechanism 3000 moves the base 1000. 1000 moves, but the base 1000 is placed on the ground and cannot move, so the first driving mechanism 3000 and the mounting base 2000 move along the arc-shaped guide rail 1100 at the same time.

As shown in FIGS. 9 to 15 , in some embodiments, the first drive mechanism 3000 includes a first driver 3100 and a first connector 3200 . The first driver 3100 and the first connector 3200 are drivingly connected, and the first driver 3100 is fixed. To one of the base 1000 and the mounting base 2000, the first connecting member 3200 is connected to the other one of the base 1000 and the mounting base 2000.

For example, the first driver 3100 is fixed on the mounting base 2000 and the first connecting member 3200 is connected on the base 1000 for explanation. The first driver 3100 can be installed into the mounting base 2000 through screwing, bonding, buckling, etc., and is immovable relative to the mounting base 2000 and can move following the movement of the mounting base 2000. The first connecting piece 3200 is connected to the base. In 1000, the power output by the first driver 3100 is transmitted to the base 1000 through the first connector 3200. Since the base 1000 is placed on the ground and is immovable, the first driver 3100 and the mounting base 2000 move along the arc-shaped guide rail 1100 as a whole. sports. Since power transmission needs to be performed at all times, the first connecting member 3200 needs to remain connected to the base 1000 .

Specifically, as shown in Figures 9 to 15, in some embodiments, the first connection member 3200 includes a first driving rod 3210 and a second driving rod 3220;

The first driving rod 3210 is provided with a first connecting part 3211 and a second connecting part 3212. The first driver 3100 and the first connecting part 3211 are connected to drive the first driving rod 3210 to rotate, and the second connecting part 3212 rotates around the A connecting part 3211 rotates, that is, when the first driving rod 3210 is driven by the first driver 3100 to rotate, the first driving rod 3210 does not rotate with its length extending direction as the rotation axis, but with its length extending direction. The intersecting (preferably vertical) direction is the rotation axis for rotation, so that the second connecting part 3212 can rotate around the first connecting part 3211 . It can be understood that the first driver 3100 may select an actuator that provides a rotational driving force output.

The second driving rod 3220 is provided with a third connecting part 3221 and a fourth connecting part 3222. The third connecting part 3221 and the second connecting part 3212 are rotatably connected. The first driver 3100 is fixed to one of the base 1000 and the mounting base 2000. , the fourth connecting part 3222 is rotatably connected to the other one of the base 1000 and the mounting base 2000, and the second driving rod 3220 can rotate within a preset angle range centered on the fourth connecting part 3222. That is, the second driving rod 3220 rotates with the direction intersecting (preferably perpendicular) to its longitudinal extension direction as the rotation axis.

In this way, when the first driver 3100 drives the first driving rod 3210 to rotate, the first driving rod 3210 rotates relative to the second driving rod 3220 at the same time, so that the relationship between the first driver 3100 and the fourth connecting portion 3222 can be changed. distance, thereby driving the mounting base 2000 to move along the arc-shaped guide rail 1100.

Further, as shown in FIGS. 9 to 11 , in some embodiments, the first connecting part 3211 is provided at one end of the first driving rod 3210 , and the second connecting part 3212 is provided at the other end of the first driving rod 3210 , so that The rotation of the first driving rod 3210 can be prevented from being blocked by other structures.

For example, the first connecting part 3211 constitutes a hole, and the second connecting part 3212 also constitutes a hole. The first connecting part 3211 is plug-connected to the driving rod of the first driver 3100, thereby driving the first driving rod 3210 to rotate, and the second connecting part 3211 is plugged into the hole. The second connecting part 3212 can be plug-connected to the third connecting part 3221 through a plug. Since the first driving rod 3210 needs to rotate under the action of the first driver 3100, the first connecting part 3211 and the second connecting part 3212 are provided at the end of the first driving rod 3210, so that the first driving rod 3210 can be shortened as much as possible. The length of the drive rod 3210 reduces the space occupied.

If the first connecting part 3211 is disposed between the two ends of the first driving rod 3210, when the first driving rod 3210 rotates, the section between the first connecting part 3211 and the end of the first driving rod 3210 can be easily aligned. Other structures cause obstructions and easily increase the required space. The same is true for the arrangement of the second connection part 3212, which will not be repeated.

Consistent with the arrangement of the first connecting part 3211 and the second connecting part 3212, in some embodiments, the third connecting part 3221 is provided at one end of the second driving rod 3220, and the fourth connecting part 3222 is provided at an end of the second driving rod 3220. On the other hand, this can prevent the rotation of the second driving rod 3220 from causing obstruction to other structures.

For example, the third connection part 3221 is also a hole, so that it can be connected to the second connection part 3212 through a plug. The fourth connection part 3222 can be an integrally formed plug, and the base 1000 is provided with a pin hole, and the plug is inserted into the base 1000. A rotatable connection is achieved in the pin hole.

Further, in some embodiments, the first driving rod 3210 rotates to form a first rotation plane, the second driving rod 3220 rotates to form a second rotation plane, and the first rotation plane is parallel to the second rotation plane, which can simplify the structure. , preventing interference between the first driving rod 3210 and the second driving rod 3220.

For example, if the first rotation plane and the second rotation plane are not parallel, the first driving rod 3210 and the second driving rod 3220 need to be set at a certain distance apart to prevent them from interfering with each other when they rotate relative to each other. If the first rotation plane and the second rotation plane are set to be parallel to each other, then the first driving rod 3210 and the second driving rod 3220 can fit as closely as possible, reducing the manufacturing difficulty of the first driving rod 3210 and the second driving rod 3220. and assembly difficulty, simplifying the structure.

As shown in FIGS. 9 to 11 , in some embodiments, the length of the first driving rod 3210 is shorter than the length of the second driving rod 3220 , which can reduce the space required for the rotation of the first driving rod 3210 and avoid causing damage to other structures. squeeze.

For example, the first driving rod 3210 rotates to drive the second driving rod 3220 to rotate within a certain angular range. If the first driving rod 3210 is designed to be smaller than the second driving rod 3220, then the angular range of the first driving rod 3210 can be The angular range of rotation is larger than that of the second driving rod 3220. This not only changes the distance between the first driver 3100 and the fourth connection part 3222, but also ensures that the space required for the rotation of the first driving rod 3210 is minimized. , especially the second connecting part 3212 can move in a circle around the first connecting part 3211, which can effectively reduce the space occupation, which will be described in detail below.

Specifically, the second connecting part 3212 can move in a circle around the first connecting part 3211, that is, the movement trajectory of the second connecting part 3212 constitutes a complete circle. In the above embodiment, the motion trajectory of the second connecting part 3212 can be an arc, and the second connecting part 3212 can reciprocate along this arc, which requires the first driver 3100 to realize forward and reverse rotation. If the second connecting part 3212 is designed so that the motion trajectory forms a complete circle, then the first driver 3100 does not need to rotate forward and reverse, and only needs to rotate in a single direction, reducing control difficulty and cost.

For example, in the orientation shown in FIGS. 9 to 15 , when the first driving rod 3210 rotates clockwise to approximately the right left, the distance between the first driver 3100 and the fourth connecting portion 3222 is the longest, which is approximately equal to the first driving rod 3210 The length is added to the length of the second driving rod 3220. At this time, the mounting base 2000 is at the rightmost end of the arc-shaped guide rail 1100. When the first driving rod 3210 then rotates clockwise to substantially facing upward, the distance between the first driver 3100 and the fourth connecting part 3222 is shortened, and the length is approximately equal to the distance between the first connecting part 3211 and the fourth connecting part 3222. At this time, the installation The seat 2000 is in the middle of the arc-shaped guide rail 1100. When the first driving rod 3210 then rotates clockwise to approximately right, the first driving rod 3210 and the second driving rod 3220 overlap each other, the distance between the first driver 3100 and the fourth connecting portion 3222 is the shortest, and the length is approximately equal to the length of the first driving rod 3210 and the fourth connecting portion 3222. The length of the second driving rod 3220 is minus the length of the first driving rod 3210. At this time, the mounting base 2000 is at the leftmost end of the arc-shaped guide rail 1100. When the first driving rod 3210 then rotates clockwise until it is generally facing directly downward, it is the same as when it is facing directly upward, and the details will not be repeated. Therefore, the first driver 3100 is designed to rotate in a single direction, so as to control the back and forth movement of the mounting base 2000 along the arc-shaped guide rail 1100 .

As shown in Figure 6, in some embodiments, the base 1000 has a receiving cavity, which is provided on opposite sides of the receiving cavity. There is an arc-shaped guide rail 1100. The arc-shaped guide rail 1100 is made of metal material and has high structural strength. Corresponding fixed structures are provided in the accommodation cavity. Both ends of the arc-shaped guide rail 1100 can be fixed to the corresponding fixed structures through plugging, screwing, bonding, etc., and are immovable relative to the base 1000, which can effectively Bearing Mount 2000.

Correspondingly, the opposite sides of the mounting base 2000 match the arc-shaped guide rail 1100 one-to-one, so that the arc-shaped guide rail 1100 supports the mounting base 2000 more stably, prevents the mounting base 2000 from being skewed, and is more conducive to the mounting base 2000. of movement.

Specifically, as shown in FIGS. 7 and 8 , in some embodiments, in order to reduce the resistance to movement of the mounting base 2000 , rollers 2100 are provided on the mounting base 2000 .

For example, on the same side of the mounting base 2000, along the length extension direction of the arc-shaped guide rail 1100, two rollers 2100 are provided at intervals. The rollers 2100 have inner concave surfaces, and the top surface of the arc-shaped guide rail 1100 forms a smooth convex surface, so that Set the roller 2100 on the top surface of the arc-shaped guide rail 1100. Since the roller 2100 has an inner concave surface, the roller 2100 will not easily break away from the arc-shaped guide rail 1100 during the movement of the mounting base 2000, ensuring the stability of the movement of the mounting base 2000. , thereby improving product reliability.

As shown in FIG. 6 , in some embodiments, one end of the arc-shaped guide rail 1100 is a first end 1110 , and the other end of the arc-shaped guide rail 1100 is a second end 1120 . The first end 1110 and the The second end is set at the same height as 1120, which can make the movement of the rocking chair smoother.

If the first end 1110 and the second end 1120 are not set at the same height, for the mounting base 2000 , the mounting base 2000 will also have different heights when it moves to the first end 1110 and the second end 1120 , and due to the arc guide rail 1100 Due to the influence of curvature, the mounting base 2000 will be more inclined when it is at the higher end. In addition, since the height and deflection angle of the mounting base 2000 when it is at the first end 1110 and the second end 1120 are different, the stability is also different. Therefore, the base 1000 needs to be positioned at the first end 1110 and the second end of the mounting base 2000. The design is carried out at 1120 to meet the stability requirements of the non-equal height settings of the first end 1110 and the second end 1120, which will increase the difficulty of designing the base 1000.

Further, as shown in Figure 6, in some embodiments, one end of the arc-shaped guide rail 1100 is the first end 1110, and the other end of the guide rail is the second end 1120. The arc-shaped guide rail 1100 has a middle section 1130, and the middle section 1130 is located at Between the first end 1110 and the second end 1120, the first end 1110 and the second end 1120 are designed to be higher than the middle section 1130. In this way, the movement of the mounting base 2000 can form a centripetal movement, similar to the movement of a swing, making the support of the entire base 1000 more stable. Especially after the rocking chair frame 5000 is installed, it can prevent the rocking chair frame 5000 from moving and causing the entire rocking chair to collapse. Tipping occurs.

As shown in FIG. 7 , in some embodiments, the base 1000 has an arc surface 1310 and the mounting base 2000 has an arc surface 2200 . The arc surface 1310 of the base 1000 and the arc surface 2200 of the mounting base 2000 are arranged oppositely.

For example, the base 1000 includes a connected upper housing 1300 and a lower housing 1400. The upper housing 1300 is provided with an arc surface 1310. The mounting base 2000 is provided with an arc surface 2200. The arc surface 1310 of the upper housing 1300 and the mounting The curved surface of the seat 2000 2200 relative settings.
