And, can also have the reset function, can reset and make ready for next transmission.

The specific mechanism involved is detailed below.

First stage-locking.

First, as shown in fig. 8a-c, the ejector member is inserted into the ejection opening of the launcher, the ejector member is inserted until it locks with the catch of the ejector member lock, the ejector member will be locked inside the launcher, while the spring is compressed by the ejector member.

Next, as shown in fig. 8d, the launcher is pressed down until it is locked with the launcher release tray.

After the above steps are completed, a loading state is formed, as shown in fig. 8d, 8e and 8f, at this time, the launcher releases the tray bottom 6 to be locked with the launcher by the locking member, and the ejection member locking device is locked with the ejection member by the hook.

Second phase-release flight.

To launch the ejection member, the user may pull the toy vehicle rearwardly until a clicking sound is heard, at which time the rear wheels move rearwardly to store kinetic energy in the coil spring gearbox; once the toy vehicle is released, kinetic energy will be released from the coil spring gearbox and propel the vehicle forward, as shown in FIG. 6.

At this time, the front wheel drives the second wheel transmission rod to rotate forwards, at this time, the thread part also rotates along with the second wheel transmission rod, as shown in fig. 4, the front wheel drives the timing gear disc to rotate anticlockwise, one end of the C-shaped opening of the formal gear disc is located at a position I right in front of the vehicle, the other end of the C-shaped opening of the formal gear disc is located at a position II where the position I rotates anticlockwise by 135 degrees, when the timing gear disc rotates from the position I to the position II, the positioning block at the bottom of the launcher releasing disc is driven to rotate by utilizing the C-shaped opening, the launcher releasing disc is driven to rotate, the extension arm pushes against the ejection component locking device, as shown in fig. 5, fig. 9a and fig. 9b, the launcher releasing disc rotates and is separated from the launcher, the launcher is lifted by.

At the same time, the extension arm of the launcher release disk pushes against the protruding abutment surface of the ejection member locker to release the launch spring and allow the ejection member to fly into the air.

The vehicle will continue to travel forward until the coil spring gearbox stops, i.e. the launch function is completed.

Third phase-return to standby position.

As shown in figure 7, the vehicle may be stopped and ready for the next launch, and the second wheel drive link may have a threaded portion attached thereto, either in the normal engaged position or in a position where the toy vehicle is lifted such that the threaded portion disengages the gear portion.

When the front wheel and the second wheel drive link are in the normal engagement position, the threaded portion engages the gear portion and the front wheel will drive the threaded portion and drive the timing gear plate to activate the launcher release plate (described in the second stage).

When the user picks up the toy vehicle in preparation for the next launch and again tightens the coil spring gearbox, the second wheel drive link of the front wheel moves downward by its own weight, causing the threaded portion to disengage from the gear portion.

This disengagement action causes the return spring to urge the launcher releasing plate back to the standby position, at which time the launcher may be ready for locking (back to the first stage initial state).

The first phase is repeated in preparation for the next transmission.

Each part of the invention can be placed at a corresponding position of the vehicle chassis according to the requirement, each part can be connected in a connection mode which can be realized by the prior art, such as screw joint, insertion, bonding and the like, and a cover plate, a shielding part and the like can also be arranged according to the requirement, which can be solved by a person skilled in the art according to the requirement and is not important in the scheme, and the description is omitted.

The invention provides a return force vehicle capable of launching an ejection member, the length of the return force vehicle is generally about 10-13 cm, a specially-made vehicle body upper cover can be customized according to requirements, the return force vehicle can carry a shell of the return force vehicle and hide the shell in the vehicle body, the shell can be ejected from the vehicle when the vehicle is released to run, the vehicle is driven by a spiral spring gearbox, the spiral spring gearbox provides power for advancing the vehicle and launching the shell when the vehicle runs, and the power of the shell is generated by a compression spring in the launcher.

The user simply slides the projectile into the mouth of the launcher until it clicks with the ejection member lock and depresses the launcher, then pulls the vehicle backwards to wind the spring, storing energy from the coil spring gearbox. Once the user releases the vehicle, kinetic energy will be released from the coil spring gearbox and the vehicle will run. Meanwhile, the launcher is unlocked and lifted, the cannonball is launched, the toy car is taken up after parking, and each locking device is reset to prepare for next use.
