Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a multi-action switching mechanism for electric toys. Background Technology

[0002] Animal toys with legs can perform actions such as walking and crouching under the drive of a mechanical device. The leg drive mechanism also includes a crank-rocker mechanism to generate the crouching motion, with the crank's central shaft connected to a forward / reverse switching mechanism in the transmission mechanism. Switching between crouching and forward movements is achieved through a connecting rod-crank rotation short shaft structure in conjunction with a spring on the connecting rod that extends from the crouching connecting rod towards the crank. However, the existing structure requires multiple connecting rods, resulting in complexity and making installation very inconvenient. Summary of the Invention

[0005] The cam is connected to the output shaft of the motor, and the motor drives the cam to rotate in the forward or reverse direction.

[0006] The squatting climbing lever has one end hinged to the left and right rear leg mechanisms and is in transmission cooperation with the left and right rear leg mechanisms. The cam and the squatting climbing lever are in cam cooperation to drive the squatting climbing lever to move forward or backward.

[0007] The transmission link is movable between the other end of the squatting and climbing buckle and the transmission link, and the transmission link limits the forward and backward movement of the squatting and climbing buckle.

[0008] An elastic element is provided on the squatting and climbing buckle bar, and the elastic element causes the squatting and climbing buckle bar to move towards the cam.

[0009] It also includes a groove, which is set in the middle of the squatting and climbing buckle, and a lever is provided on the cam. The cam cooperates with the grooved cam on the squatting and climbing buckle through the lever.

[0010] The squatting and climbing levers on both sides of the outer side of the groove have steps formed. The lever of the cam includes a left and right rear leg mechanism movement switching position that cooperates with the cam of the groove and an idle position that interacts with the steps on both sides of the outer side of the groove.

[0011] The cam has a lever on each side of its circumference at the center of its upper edge.

[0012] The squatting and climbing buckle and the transmission link are connected by a shaft to achieve transmission.

[0013] The cam also includes a chassis, and the chassis and the squatting hook are matched to prevent the squatting hook from shifting outward.

[0014] It also includes a base, with one end of the elastic element connected to the squatting and climbing bar and the other end connected to the base.

[0015] The base is also provided with a limiting block, and the squatting climbing lever and the left and right rear leg mechanisms are respectively limited by the limiting block to achieve the limitation of the squatting climbing lever in the forward and backward movement direction.

[0016] The elastic element is a tension spring.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a multi-action switching mechanism for an electric toy, including a motor and left and right rear leg mechanisms, and also includes a cam. The cam is driven by the output shaft of the motor, and the motor drives the cam to rotate in the forward or reverse direction.

[0025] 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.

[0026] The electric toy's multi-action 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 crouching / climbing lever 3 is also included, with one end hinged to the left and right rear leg mechanisms 1 and driven by them. The cam 2 engages with the crouching / climbing lever 3, causing it to move forward or backward. A slot 31 is also included, located in the middle of the crouching / climbing lever 3. A lever 21 is mounted on the cam 2, with a lever 21 on each side of the cam 2's center. The cam 2 engages with the cam in the slot 31 on the crouching / climbing lever 3 via the levers 21. Steps 32 are formed on the crouching / climbing lever 3 on both sides of the slot 31. The levers 21 of the cam 2 include a position for switching the movement of the left and right rear leg mechanisms 1, engaging with the cam in the slot 31, and an idle position that interacts with the steps 32 on both sides of the slot 31. A transmission link 4 is included, with the other end of the squatting hook 3 movably connected to it. The squatting hook 3 and the transmission link 4 are connected by a shaft to achieve transmission. The transmission link 4 limits the forward and backward movement of the squatting hook 3. An elastic element 5, which is a tension spring, is located at one end of the squatting hook 3 near the left and right rear leg mechanisms 1. The elastic element 5 guides the squatting hook 3 towards the cam 2, preventing it from slipping on the cam 2. This invention simplifies existing transmission mechanisms that require additional links and elastic elements by connecting both ends of the squatting hook to the transmission link and the left and right rear leg mechanisms respectively, and combining the elastic element to limit the forward and backward movement and longitudinal movement of the squatting hook.

[0027] The cam 2 also includes a chassis 22, which is matched with the squatting and climbing lever 3 to prevent the squatting and climbing lever 3 from shifting outward.

[0028] It also includes a base 6, with one end of the elastic element 5 connected to the squatting climbing lever 3 and the other end connected to the base 6. The base 6 is also provided with a limiting block 61, and the squatting climbing lever 3 and the left and right rear leg mechanisms 1 respectively cooperate with the limiting block 61 to limit the forward and backward movement of the squatting climbing lever 3.

[0029] When the motor rotates clockwise, the lever on the cam engages with the slot on the squatting and climbing lever 3, causing the squatting and climbing lever 3 to move forward. The forward movement of the squatting and climbing lever 3 causes the left and right rear leg mechanisms 1 to move forward. Then, the lever on the cam interacts with the step on the right side of the slot.

[0030] When the motor rotates counterclockwise, the lever on the cam engages with the slot on the squatting and climbing lever (3), causing the squatting and climbing lever (3) to move backward. The backward movement of the squatting and climbing lever (3) causes the left and right rear leg mechanisms 1 to move backward to complete the standing action. Then, the lever on the cam interacts with the step on the left side of the slot.
