[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] An electric toy's upright / reclining motion switching mechanism includes a motor and left and right rear leg mechanisms 1, as well as a cam 2. The cam 2 is driven by the output shaft of the motor, and the motor drives the cam 2 to rotate forward or backward. A first connecting rod 3 is hinged to the left and right rear leg mechanisms 1 and is driven by them. A second connecting rod 4 is driven by the cam 2 to move forward or backward. The second connecting rod 4 is axially connected to the first connecting rod 3, and the second connecting rod 4 drives the first connecting rod 3 to move forward or backward. Both the first and second connecting rods are crank-connecting rods. A first elastic element 5 connects the first connecting rod 3 and the second connecting rod 4, causing the second connecting rod 4 to move towards the cam and preventing slippage between the second connecting rod 4 and the cam. A guide groove 31 is located at the end of the first connecting rod near the cam 2. The guide groove has an upward bending structure. A guide shaft 21 is mounted on the cam 2 and guides the guide groove 31. A second elastic element 6 is connected to the first connecting rod 3, causing the first connecting rod 3 and the second connecting rod 4 to move towards the cam. Both the first connecting rod 3 and the second connecting rod 4 are provided with hook-shaped structures 7, and the first elastic element 5 is disposed on the hook-shaped structures 7 on the first connecting rod 3 and the second connecting rod 4. A base is also included, and the bottom of the first connecting rod is also provided with a hook-shaped structure 7. The second elastic element 6 is disposed between the hook-shaped structure 7 at the bottom of the first connecting rod and the base. This utility model simplifies the upright / downward motion switching mechanism of an electric toy by setting a first elastic element between the first and second connecting rods and a second elastic element at the bottom of the first connecting rod, causing the first and second connecting rods to move towards the cam, thus making installation easier.

[0029] It also includes a groove 41, which is located at the end of the second connecting rod 4. The cam 2 has a lever 22, which engages with the cam in the groove 41 on the second connecting rod 4 via the lever 22. Steps 42 are formed on both sides of the second connecting rod 4 outside the groove 41. The lever 22 of the cam 2 includes a vertical / horizontal switching position that engages with the cam in the groove 41 and a free-spinning position that interacts with the steps 42 on both sides of the groove 41. A lever 22 is located on each side of the circumference along the center of the cam 2.

[0030] The first link 3 and the second link 4 are both provided with hook-shaped structures 7, and the first elastic element 5 is provided on the hook-shaped structures 7 on the first link 3 and the second link 4.

[0031] Both the first elastic element 5 and the second elastic element 6 are tension springs.

[0032] When the motor rotates clockwise, the lever 22 on the cam 2 engages with the slot 41 on the second link 4, causing the second link 4 and the first link 3 to move backward. The backward movement of the first link 3 causes the left and right rear leg mechanisms 1 to move backward to complete the prone position. Then, the lever 22 on the cam 2 interacts with the step 42 on the left side of the slot 41.

[0033] When the motor rotates counterclockwise, the lever 22 on the cam 2 engages with the slot 41 on the second link 4, driving the second link 4 and the first link 3 to move forward. The first link 3 moves backward, driving the left and right rear leg mechanisms 1 to move forward to complete the standing action. Then, the lever 22 on the cam 2 interacts with the step 42 on the right side of the slot 41.
