For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an indirect connection through an intermediate medium, but the connections at various locations do not affect the multi-position folding of the present application. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1-10The figure shows a specific embodiment of a child-accompanying seesaw, which is a child-accompanying seesaw, including a bracket plate 1, an adult chair 2, and a child chair 3. The bracket plate 1 is provided with a horizontal slide groove 1.1 and a vertical slide groove 1.2. The adult chair 2 is connected to a No. 1 connecting plate a, and the end of the No. 1 connecting plate a extends upwardly to form a No. 2 connecting plate b. The end of the No. 1 connecting plate a is connected to a sliding shaft 2.1 located in the horizontal slide groove 1.1, and the sliding shaft 2.1 can slide left and right along the horizontal slide groove 1.1. The child chair 3 is connected to a No. 3 connecting plate c, and the No. 3 connecting plate c is connected to a slider 3.1 located in the vertical slide groove 1.2, and the slider 3.1 can slide up and down in the vertical slide groove 1.2. The No. 2 connecting plate b is hinged to the No. 3 connecting plate c. In order to realize the linkage between the adult chair 2 and the child chair 3, the horizontal slide groove 1.1 in the present application mainly plays a role in constraining the movement of the sliding shaft 2.1, and it can be replaced by the following technical solutions, such as when the sliding shaft 2.1 and the horizontal slide groove 1.1 are connected by rollers (at this time, the horizontal slide groove 1.1 and the sliding shaft 2.1 are adapted in size, and the vertical slide groove 1.1 is an arc-shaped slide groove) to achieve the same technical effect, the vertical slide groove 1.1 in the present application mainly plays a role in constraining the movement of the slider 3.1, and it can be replaced by the following technical solutions, the slider 3.1 and the vertical slide groove 1.1 are connected by rollers to achieve the same technical effect, the rotating shaft 3.2 and the rotating hole 2.2 in the present application are hinged, and it can be replaced by the following technical solutions, the rotating shaft 3.2 and the rotating hole 2.2 are connected by ball bearings to achieve the same technical effect;

[0032] The seat movement trajectory of the adult chair 2 is a nearly elliptical long axis end point that rotates up and down. The use process is: under the action of external force, when the adult chair 2 moves downward, it first uses the sliding shaft 2.1 as a fulcrum, and the end of the second connecting plate b is tilted, so that the slider 3.1 is driven to move upward in the vertical slide groove 1.2. When the slider 3.1 moves upward, the sliding shaft 2.1 simultaneously moves to the right along the horizontal slide groove 1.1, and continues to press the adult chair 2 downward. After the sliding shaft 2.1 continues to move to the right, the supporting force of the horizontal slide groove 1.1 on the sliding shaft 2.1 increases, and the slider 3.1 continues to move upward until it moves to the limit position of the gap between the horizontal slide groove 1.1 and / or the vertical slide groove 1.2 and stops. When the pressure on the adult chair 2 is relieved, the whole process moves in the opposite direction under the action of the gravity of the child chair 3. The creativity of the present invention lies in the use of a group of connecting rod mechanisms (including connecting plate No. 1 a, connecting plate No. 2 a, and connecting plate No. 3 c), combined with sliding and rotating movements, to achieve rotational reciprocating motion on one side of the seesaw and vertical reciprocating motion on the other side, thereby solving the problem that young children are unable to control conventional seesaws and are at risk of movement.

[0033] In a preferred embodiment, the sliding shaft 2.1 is rotatably connected to the end of the No. 1 connecting plate a, so that the sliding shaft 2.1 can slide left and right in the transverse sliding groove 1.1 and rotate around the transverse sliding groove 1.1 in the normal direction, thereby reducing the friction between the sliding shaft 2.1 and the transverse sliding groove 1.1 and improving the service life.

[0034] In a preferred embodiment, the third connecting plate c is connected with a guardrail 3.3 located above the child chair 3, the guardrail 3.3 is composed of a rod connected end to end, the rear end of the guardrail 3.3 is connected with a backrest, the front end of the guardrail 3.3 is connected with a handrail, and the handrail is an inverted "U" shaped structure. The function of the guardrail 3.3 is to protect the child on the child chair 3 from injury during exercise. Therefore, the connection between the guardrail 3.3 and the third connecting plate c can adopt a reversible connection structure (such as a rotating shaft with a limiter), a detachable structure (such as screws), and a front-to-back distance telescopic adjustment structure (such as nested telescopic), which is convenient for users to use, and these structures are all commonly used technical means. In order to realize a vehicle that accommodates children of different body sizes, the child chair 3 preferably adopts the method of adjusting the front and rear distance of the seat to adapt to the child's body size.

[0035] In a preferred embodiment, the No. 1 connecting plate a and the No. 2 connecting plate b are integrally formed and constitute a side panel, two side panels are provided, and the two side panels are symmetrically arranged on the left and right sides of the bracket plate 1, the sliding shaft 2.1 is connected between the two No. 1 connecting plates a, and two No. 3 connecting plates c are provided, and the two No. 2 connecting plates b are respectively located on the outside of a No. 3 connecting plate c and are respectively hinged.

[0036] In a preferred embodiment, the height of the horizontal slide groove 1.1 is the same as the height of the bottom end of the vertical slide groove 1.2. When the child chair 3 is at the lowest point, the second connecting plate b is horizontal with the horizontal slide groove 1.1. Preferably, when the slider 3.1 is at the bottom end of the vertical slide groove 1.2, the sliding shaft 2.1 is at the leftmost end of the horizontal slide groove 1.1. The two positions are limited synchronously, making the structure firm. It is also possible to adopt the method that when the slider 3.1 is at the bottom end of the vertical slide groove 1.2, the sliding shaft 2.1 is not synchronously located at the leftmost end of the horizontal slide groove 1.1, and the overall limit is only performed by the vertical slide groove 1.2, but the disadvantage is that the pressure on the bottom end of the vertical slide groove 1.2 is relatively large. It is also possible to adopt the method that when the sliding shaft 2.1 is at the leftmost end of the horizontal slide groove 1.1, the slider 3.1 is not synchronously located at the bottom end of the vertical slide groove 1.2, and the overall limit is only performed by the horizontal slide groove 1.1, but the disadvantage is that the pressure on the leftmost end of the horizontal slide groove 1.1 is relatively large.

[0037] In a preferred embodiment, when the slider 3.1 is located at the top of the vertical slide groove 1.2, the slide shaft 2.1 is located at the rightmost end of the horizontal slide groove 1.1, and both sides are limited at the same time to share the pressure and improve the stability of the structure.

[0038] In a preferred embodiment, an inclined edge is formed by cutting the upper left corner of the bracket plate 1. In the present application, the end of the No. 1 connecting plate a is inclined upward and extends to form a No. 2 connecting plate b. The No. 1 connecting plate a is horizontal with the chair surface of the adult chair 2. The power of the seesaw comes from the operation of the adult chair 2. Since the No. 1 connecting plate a and the No. 2 connecting plate b form an obtuse angle structure, the upper left corner of the bracket plate 1 is cut to form an inclined edge, which facilitates the large-scale movement of the No. 1 connecting plate a and the No. 2 connecting plate b, so that the children's chair 3 can perform a larger distance of vertical reciprocating motion.

[0039] In a preferred embodiment, the second connecting plate b is provided with a rotating hole 2.2 at the end, and the third connecting plate c is connected with a rotating shaft 3.2, which is rotatably connected in the rotating hole 2.2 and rotates around the central axis of the rotating hole 2.2. The rotating shaft 3.2 and the rotating hole 2.2 are a specific rotatable connection method, which can be replaced by a universal ball and a universal ball seat. Figure 2 , Figure 3 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 As shown, the sliding shaft 2.1 can slide left and right in the horizontal sliding groove 1.1 and rotate around the horizontal sliding groove 1.1 in the normal direction; the sliding block 3.1 can slide up and down in the vertical sliding groove 1.2; and the rotating shaft 3.2 can rotate around the central axis of the rotating hole 2.2.

[0040] In a preferred embodiment, the slider 3.1 is located between two No. 3 connecting plates c, and the slider 3.1 and the rotating shaft 3.2 are integrally arranged, with a simple structure and strong practicality.

[0041] In a preferred embodiment, the first connecting plate a, the second connecting plate b, the third connecting plate c, and the bracket plate 1 are all provided with notches, the notches on the first connecting plate a and the second connecting plate b are not strip-shaped and have semicircular ends, and the notch on the third connecting plate c is triangular; there are two notches on the bracket plate 1, one of which is concave upward from the bottom edge of the bracket plate 1 into a U shape, and the other is triangular. The multi-notch design improves the overall beauty and can save material costs.

[0042] A preferred embodiment is as follows: Figure 2 , Figure 5 , Figure 8 , Fig.10As shown, the seat movement trajectory of the adult chair 2 is a nearly elliptical long axis end point that rotates up and down. When the adult chair 2 moves downward, with the sliding shaft 2.1 as the fulcrum, the rotating hole 2.2 drives the rotating shaft 3.2 and the slider 3.1. Under the constraint of the vertical slide groove 1.2, the slider 3.1 moves upward. After the slider 3.1 moves upward, the supporting force of the horizontal slide groove 1.1 on the sliding shaft 2.1 is reduced. After the sliding shaft 2.1 moves to the right under the continuous downward force of the seat 2, the supporting force of the horizontal slide groove 1.1 on the sliding shaft 2.1 increases, and the slider 3.1 continues to move upward, and it moves to the limit position of the gap between the horizontal slide groove 1.1 and the vertical slide groove 1.2 and stops. When the pressure on the adult chair 2 is relieved, the connecting rod mechanism moves in the opposite direction under the action of the gravity of the child chair 3.

[0043] The use of the present invention is as follows: Figure 1-10 As shown, the seesaw can realize the rotational reciprocating motion of the adult chair 2 and the vertical reciprocating motion of the child chair 3 at the same time.

[0044] Use status 1: Figure 1-3 In the state shown, when preparing for use or finishing use, the user of the adult chair 2 puts both feet on the ground and relies on the leg strength to maintain a balanced state with the weight of the child chair 3. The adult chair 2 and the child chair 3 are at similar heights, and the sliding shaft 2.1 and the slider 3.1 are respectively located near the middle of the horizontal slide groove 1.1 and the vertical slide groove 1.2. During use, the movement of the seesaw will also experience the position shown in the figure.

[0045] Use status 2: Figure 4-6 In the state shown, when the user of the adult chair 2 presses down the seat, the adult chair 2 descends, the slide shaft 2.1 slides rightward to the limit position in the horizontal slide groove 1.1, and the slider 3.1 slides upward to the limit position in the vertical slide groove 2.1, driving the child chair 3 to rise to the highest safety position. The slider 3.1 may not have a rotating shaft structure.

[0046] Use status 3: Figure 7 , Figure 8 In the state shown, when the user of the adult chair 2 reduces the downward pressure and moves the hips upward, the adult chair 2 rises, the slide shaft 2.1 slides leftward to the limit position in the horizontal slide groove 1.1, and the slider 3.1 slides downward to the limit position in the vertical slide groove 2.1, driving the child chair 3 to descend to the lowest safety position. The slider 3.1 may not have a rotating shaft structure.

[0047] Finally, it should be noted that the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by ordinary technicians in this field should be considered as the protection scope of the present invention.
