After being disengaged, the corresponding launcher release plate 6 is reset by the return spring 8, and at this time, the ejection part locking device 5 is pressed down again to return to the locked state.

The general working principle of the present utility model is as follows: when playing the toy car of the present utility model capable of launching ejection parts, the ejection parts (for example: shells) need to be pressed into the launcher 4 through the launch port 43 at first, as shown in FIG. 3 and FIG. shown. The vehicle's power is provided by a coil spring gearbox 2, which is assembled with the rear wheels. A threaded portion 221 is provided on the second wheel drive rod 22 of the front wheel, and the threaded portion is used to drive the launcher release plate 6 and the timing gear plate 7 to activate the launcher to raise and shoot the projectile from the launcher. And, it can also have a reset function that can reset to be ready for the next launch.

The specific mechanisms involved are detailed below.

Phase 1 - Lockdown.

First, as shown in Figures 8a-c, insert the ejection member into the launch port of the launcher, the ejection member is inserted until it locks with the hook of the ejector locker, the ejection member will be locked inside the launcher, and the spring is Ejection parts are compressed.

Next, as shown in Figure 8d, push the launcher down until it locks with the launcher release disc.

After the above steps are completed, the loaded state is formed, as shown in Fig. 8d, Fig. 8e and Fig. 8f. At this time, the launcher releases the bottom plate 6 and the launcher is locked by the clamping part, and the ejection part locker and the ejection part are locked by the clamping part. Hook lock.

The second stage - release flight.

To fire the ejector, the user pulls the toy car backwards until a click of the vehicle is heard, at which point the rear wheels move backward storing kinetic energy in the coil spring gearbox; once the toy car is released, the kinetic energy will be shifted from the coil spring The box releases and propels the vehicle forward as shown in Figure 6.

At this time, the front wheel drives the second wheel transmission rod to rotate forward, and the threaded part also rotates accordingly. As shown in Figure 4, it drives the timing gear plate to rotate counterclockwise. The C-shaped opening end of the formal gear plate is located at Position I in front of the vehicle, and the other end is at position II, which is rotated 135° counterclockwise from position I. When the timing gear plate rotates from position I to position II, use the C-shaped opening to drive the transmitter to release the positioning block at the bottom of the plate , to drive the rotation of the launcher release plate to rotate, and make the extension arm push against the ejection part locking device, as shown in Figure 5, Figure 9a, Figure 9b, the launcher release plate rotates and separates from the launcher, and the launcher torsion spring makes the launcher The launcher is raised by 40°, which also provides the best launch distance and launch height for the ejector components.

At the same time, the extending arm of the launcher release plate pushes against the protruding abutment surface of the ejector latch to release the launch spring and allow the ejector to fly into the air.

The vehicle will continue to drive forward until the coil spring transmission stops, ie the launch function is completed.

Stage 3 - Return to standby position.

As shown in Figure 7, after the vehicle stops, it can prepare for the next launch. The second wheel transmission rod is connected with a threaded portion. The second wheel transmission rod can be in the normal engagement position, or it can be in the lower position when the toy car is lifted. , so that the threaded part is disengaged from the gear part.

When the front and second wheel drive rods are in the normal engagement position, the threaded portion meshes with the gear portion and the front wheel will drive the threaded portion and drive the timing gear disc to activate the transmitter release disc (described in the second stage).

When the user picks up the toy car to prepare for the next launch, and tightens the coil spring gearbox again, the second wheel transmission rod of the front wheel moves downward by its own weight, so that the threaded part is disengaged from the gear part.

This disengagement action causes the return spring to push the transmitter release plate back to the standby position, at which point the transmitter is ready for locking (returning to the first stage initial state).

Repeat the first stage to prepare for the next launch.

The various components of the utility model can be placed in the corresponding positions of the vehicle chassis according to the requirements, and the various components can be connected by the connection methods that can be realized in the prior art, such as screwing, plugging, bonding, etc. The shielding member, etc., can be solved by those of ordinary skill in the art according to their own needs, and it is not the focus of this case, and will not be repeated here.

The utility model provides a pull-back vehicle capable of launching ejection parts, the length is generally about 10-13 centimeters, a specially-made upper cover of the body can be customized according to the requirements, and it can carry its own shells and hide the shells in the body, The projectiles can be fired from the vehicle while the vehicle is being released for travel. The vehicle is driven by a coil spring gearbox, which provides power for the forward movement of the vehicle and the firing of the projectile while the vehicle is moving. The power of the projectile is generated by a compression spring in the launcher.

The user simply slides the shell into the launcher's opening until it clicks with the ejector latch, depresses the launcher, and winds the car back to store the spring from the coil spring gearbox. energy of. Once the user releases the vehicle, kinetic energy will be released from the coil spring gearbox and the vehicle will run. At the same time, the launcher is unlocked and lifted, and shells are fired. After parking, the toy car is picked up, and each locking device is reset to prepare for the next use. The structure is novel and interesting.
