Description

Technical Field

[0001] The utility model relates to the technical field of robots, and in particular to an electric hand cannon for a transformable robot. Background Art

[0002] Existing robot toys may be provided with different shapes, for example, a backpack, a sword, a hand cannon, etc. may be provided on the torso of the robot, but most of these additional parts are models, lacking operability and interest.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN201862263U discloses a transformable toy, which consists of a robot base, a shell launching mechanism, a shell group and a machine group. The utility model realizes the organic combination of the toy robot base, the robot and the performance stage. The toy robot base can not only transform with the robot, but also can be transformed from the combat mode of the toy robot base to the performance mode. While providing a base for other robots, it can also be transformed into a robot to participate in the battle, and can also be used as a stage for robot performances. The base itself can also be used as a combat tool. The outer shell part can be used to celebrate as a robot and can be used as a toy alone, and so on. Therefore, the utility model has a very strong interest and is suitable for toy lovers of different ages. However, the shell launching mechanism in the transformable robot is just a shape, and it cannot really launch shells, which lacks interest. Utility Model Content

[0004] In order to solve the above-mentioned technical defects existing in the prior art, the purpose of the utility model is to provide an electric hand cannon for a transformable robot, which can automatically extend and retract the barrel by driving a servo, and has three lights and can manually fill the shells and automatically fire them during the automatic extension and retraction process, thereby increasing the visual effect and playability of the robot.

[0005] In order to achieve the above design objectives, the scheme adopted by the utility model is as follows:

[0006] The utility model is an electric hand cannon for a transformable robot. The electric hand cannon comprises a shell, a barrel at the front end of the shell, and a breech block at the rear end of the shell. The barrel comprises a shell, a steering gear inside the shell, a cannonball launching mechanism, and a gear outside the shell. The steering gear is fixedly connected to the gear by screws. When the robot is working, the steering gear transmits power (rotational motion) to the gear. The gear cooperates with the rack on the shell to push the barrel forward and backward automatically. The cannonball launching mechanism comprises a mechanism shell and a trigger device. The front end of the trigger device abuts against the mechanism shell. The electric barrel of the utility model can launch cannonballs, which increases the fun of the robot.

[0007] Preferably, a thrust spring and a thrust slider are provided inside the mechanism housing, and the thrust spring is placed inside the thrust slider; and a chamber retention spring is provided on the trigger device.

[0008] When a cylindrical long-rod shell is manually pushed into the gun barrel, the head of the shell hits the thrust slider and pushes the thrust slider inward. The thrust slider compresses the thrust spring to store elastic potential energy. After the thrust slider moves to the trigger device, it lifts the trigger device and continues to move inward. Then the trigger device buckles the thrust slider under the action of the loading retention spring; the gun barrel contracts inward under the drive of the servo when it is fully extended. During this process, the shell will press down the rear end of the trigger device, lifting the front end of the trigger device. The restriction on the forward movement of the thrust slider is removed, and the elastic potential energy of the thrust spring is released, thereby pushing the shell forward to fire.

[0009] In any of the above schemes, preferably, the housing includes a left housing and a right housing, and a circuit board with a rear travel switch, a circuit board with a front travel switch, a steering gear and a rack are arranged between the left housing and the right housing. The telescopic movement of the gun barrel presses the travel switches on the two circuit boards at the front and rear extreme positions respectively, and controls the steering gear in the gun barrel to stop moving.

[0010] In any of the above schemes, it is preferred that the rack cooperates with the gear, and the servo engine transmits power (rotational motion) to the gear after operation, and the gear cooperates with the rack to push the gun barrel forward and backward automatically.

[0011] In any of the above schemes, preferably, the breech block includes a breech block housing, a circuit board with lamp beads and a spring wire are arranged in the breech block housing, and the spring wire provides electric energy for the breech block moving forward and backward. The electric breech block of the utility model can fire cannonballs, which increases the fun of the robot.

[0012] In summary, the electric hand cannon for a transformable robot of the utility model has the following advantages: the barrel can be automatically extended and retracted by driving a servo; a circuit board with light beads is provided in the tail of the barrel to increase the visual effect; the manually filled shells are automatically fired during the automatic extension and retraction process, which increases the visual effect of the robot and its playability.
