DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figures 1 to 14 The utility model provides a technical solution: a propeller impact ejection toy airplane, comprising a lower casing 1, an impact assembly 2, an upper casing 3 and a rotor 4. The lower casing 1 and the upper casing 3 are engaged with each other by buckles to form a complete toy airplane shell. The lower casing 1 is respectively provided with front wheels 11 and rear wheels 12 in a front-to-back distribution state. The front wheels 11 and the rear wheels 12 are used to realize the movement of the propeller impact ejection toy airplane. The impact assembly 2 is provided between the lower casing 1 and the upper casing 3, and the part of the impact assembly 2 protruding from the toy airplane shell is provided with an impact head 21. When the propeller impact ejection toy airplane encounters an obstacle when moving forward, the impact head 21 first collides with the obstacle. The upper casing 3 is provided with rotor mounting holes 31 on both sides, and the rotor mounting holes 31 are provided with rotors 4. When the propeller impact ejection toy airplane collides with an obstacle, the rotor 4 can fly upward.
[0030] A safety buckle 41 plugged into the upper casing 3 is provided at the wing blade of the rotor 4, and the safety buckle 41 is U-shaped. When it is not necessary to achieve the special effect of causing the rotor 4 to fly up after the impact head 21 collides with an obstacle, the two ends of the U-shaped safety buckle 41 are respectively inserted into the corresponding sockets on the upper casing 3 to fix the rotor 4, ensuring that even if a collision occurs or the impact propeller ejection toy airplane encounters a collision during transportation, the rotor 4 will not be separated from the upper casing 3, and it plays a role similar to a safety pin.
[0031] The side of the impact head 21 facing the tail is connected with an inclined guide platform 22, and a reset tension spring 221 is connected between the inclined guide platform 22 and the lower housing 1. When the impact head 21 collides with an obstacle, the inclined guide platform 22 moves backward synchronously due to the impact force, and the inclined surface of the inclined guide platform 22 abuts against two groups of rotating frames 23. The junctions of the two groups of rotating frames 23 and the inclined surface are provided with convex points 231. The convex points 231 are in contact with the inclined surface of the inclined guide platform 22, so that the resistance to the relative movement between the inclined guide platform 22 and the rotating frame 23 is reduced, and the relative movement process is more The rotating frame 23 and the lower housing 1 are smoothly and smoothly connected, and a rotating structure is formed between the two sets of rotating frames 23 and the lower housing 1 by using a rotating shaft 232. As the inclined guide platform 22 moves backward, the protruding point 231 in contact with the inclined surface thereon slides down along the inclined surface. At this time, the rotating frame 23 rotates with the rotating shaft 232 as the rotation center. At this time, the reset tension spring 221 is in a stretched state. A U-shaped clamp 233 is provided at one end of the rotating frame 23 away from the protruding point 231. At this time, as the rotating frame 23 rotates, the U-shaped clamp 233 moves downward, and the ejection assembly 24 is clamped on the inner side of the U-shaped clamp 233.
[0032] The ejection assembly 24 includes a receiving platform 241, a lower anti-return platform 242 and an upper anti-return platform 243. The receiving platform 241 is provided with brackets on both sides thereof that are engaged with the lower side of the U-shaped clamping head 233. When the U-shaped clamping head 233 rotates with the rotating frame 23, the U-shaped clamping head 233 drives the receiving platform 241 to move downward, and a central column 2412 is provided at the upper center position of the receiving platform 241. Three sets of elastic anti-return strips 2411 are provided around the end rod body of the central column 2412. The rod body of the column 2412 passes through the lower check platform 242 and the upper check platform 243 in sequence. The inner ring of the bottom side of the lower check platform 242 is provided with a check tooth 2421 matching the elastic check strip 2411. The meshing action between the elastic check strip 2411 and the check tooth 2421 limits the relative movement between the lower check platform 242 and the upper check platform 243. As the receiving platform 241 moves downward, the elastic check strip 2411 and the check tooth 2421 are disengaged.
[0033] A clamping hole 42 is provided at the connection between the rotor 4 and the upper check-back platform 243, and matching check-back racks are provided at the upper rod body of the upper check-back platform 243 and the inner hole of the clamping hole 42. The rotor 4 is rotatably installed on the ejection assembly 24 by utilizing the matching check-back racks provided at the upper rod body of the upper check-back platform 243 and the inner hole of the clamping hole 42. A torsion spring 244 is provided between the lower check-back platform 242 and the upper check-back platform 243, and one end of the torsion spring 244 is fixed to the frame body of the rotating frame 23, and the other end of the torsion spring 244 is fixed to the lower rod body of the upper check-back platform 243. At this time, the torsion spring 244 is in a power storage state as the upper check-back platform 243 rotates. The elastic check strip 2411 and the check tooth 2421 are disengaged, so that the upper check platform 243 rotates under the action of the torsion spring 244, thereby driving the rotor 4 to rotate and be ejected out of the rotor mounting hole 31 as the torsion spring 244 resets. A return spring 245 is arranged between the receiving platform 241 and the lower casing 1. When the receiving platform 241 moves downward, the return spring 245 is in a compressed state. As the rotor 4 rises, the elastic force of the return spring 245 causes the elastic check strip 2411 and the check tooth 2421 to mesh again, so that the rotor 4 can be installed again, and the rotor 4 will rise when the impact head 21 collides with an obstacle next time.
[0034] Working principle: When the impact propeller is used to launch a toy airplane, the rotor 4 is rotated and installed on the ejection assembly 24 under the action of the matching check racks arranged at the upper rod body of the upper check platform 243 and the inner hole of the clamping hole 42. When the impact propeller launches the toy airplane and encounters an obstacle while moving forward, the impact head 21 first collides with the obstacle. When the impact head 21 collides with the obstacle, the inclined guide platform 22 moves backward synchronously due to the impact force. As the inclined guide platform 22 moves backward, the convex point 231 in contact with the inclined surface thereon slides down along the inclined surface. At this time, the rotating frame 23 rotates with the rotating shaft 232 as the rotation center. At this time, as the rotating frame 23 rotates, the U-shaped clamping head 233 drives the receiving platform 241 downward. The upper check platform 243 rotates under the action of the torsion spring 244, thereby driving the rotor 4 to rotate and be ejected out of the rotor mounting hole 31 as the torsion spring 244 resets. When the receiving platform 241 moves downward, the reset spring 245 is in a compressed state. As the rotor 4 rises, the elastic force of the reset spring 245 causes the elastic check strip 2411 to mesh with the check tooth 2421 again, so that the rotor 4 can be installed again. At the same time, the inclined guide platform 22 is reset under the elastic force of the reset tension spring 221, so that the rotor 4 can rise when the impact head 21 collides with an obstacle next time.
