It is slidably arranged on the power base 11; the ejection base 100 is provided with an ejection slot, and the ejection assembly 20 is slidably arranged in the ejection slot; the conversion assembly 40 is slidably arranged on the power base 11, and one end of the conversion assembly 40 is against the ejection assembly 20, and the other end thereof is movably connected to the rotating shaft of one of the sliding gears 13; the trigger assembly 50 is telescopically and movably arranged on the ejection base 100, and the trigger assembly 50 is engaged with the ejection assembly 20.

[0034] Specifically, two slide grooves 14 are provided on the power base 11 at intervals, the two sliding gears 13 are slidably disposed in the corresponding slide grooves 14, and the driving gear 12 is located between the two sliding gears 13 and is movably engaged with the two sliding gears 13. The conversion assembly 40 includes a conversion push rod 41 and a push rod spring 42. The conversion push rod 41 is telescopically disposed on the power base 11 through the push rod spring 42. One end of the conversion push rod 41 abuts against the ejection assembly 20, and the other end thereof abuts against one of the sliding gears 13.

[0035] In addition, the ejection base 100 is provided with two transmission assemblies 101, which are respectively connected to the two sliding gears 13, and the output ends of the two transmission assemblies are respectively located on one side of the clamping parts 21 of the two ejection assemblies 20, and are used to cooperate with the ejection wheel 60 clamped on the clamping parts 21. In this embodiment, the transmission assembly 101 is composed of a plurality of driven gears connected in sequence.

[0036] The ejection assembly 20 includes a clamping portion 21, a slide portion 22, an ejection portion 23 and a buckle portion 24, wherein the clamping portion 21 is disposed at one end of the slide portion 22, the ejection portion 23 and the buckle portion 24 are disposed at the other end of the slide portion 22, and the ejection portion 23 and the buckle portion 24 are disposed separately at the other end of the slide portion 22. The ejection portion 23 includes a sleeve rod and an ejection spring 25 sleeved on the sleeve rod, and one end of the ejection spring 25 away from the sleeve rod abuts against the ejection base 100; one end of the buckle portion 24 is fixed to the slide portion 22, and the other end thereof is engaged with the trigger assembly 50.

[0037] The buckle portion 24 of this embodiment includes a clamping rod, one end of which is fixedly mounted on the slide portion 22, and the other end of which is extended upward to be provided with a right-angled trapezoidal protrusion, and the right-angled end of the right-angled trapezoidal protrusion is close to one side of the slide portion; the trigger assembly 50 includes a trigger portion 51 and a trigger spring 52, one end of the trigger portion 51 is extended outward to be provided with a square block, so that when the ejection assembly 20 presses the ejection spring 25, one end of the clamping rod presses the square block of the trigger assembly 50 through the inclined surface of the right-angled trapezoidal protrusion, so that the trigger portion 51 moves up and presses the trigger spring 52 until the right-angled end of the right-angled trapezoidal protrusion of the clamping rod is engaged with the square block of the trigger portion.

[0038] The clamping portion 21 of the present embodiment includes a fixed portion 201 and a movable portion 202, wherein the movable portion 202 is twistably arranged on the fixed portion 201 through a twisting member, and the fixed portion 201 and the movable portion 202 together form an arc-shaped clamping position. In the present embodiment, the fixed portion 201 is slidably arranged in the ejection slot of the ejection base 100. When in use, the clamping portion 21 of the ejection assembly 20 of the present embodiment is used to clamp and fix the ejection wheel 60. The movable portion 202 twists outwardly so that the space of the arc-shaped clamping position is increased. When the ejection assembly 20 shrinks inwardly, the movable portion 202 is retracted into the ejection slot and the arc-shaped clamping position is reduced, so that the ejection wheel 60 can be rotatably sleeved in the arc-shaped clamping position.

[0039] In addition, a launch slider 53 is also provided on one side of the trigger portion 51. The launch slider 53 is slidably disposed on the outer surface of the ejection base 100, and the launch slider 53 is used to drive the trigger portion 51 to disengage from the buckle portion 24 of the ejection assembly 20. In this embodiment, the trigger portion 51 is driven to press the trigger spring 52 by sliding the launch slider 53, so that the square block below the trigger portion 51 and the buckle portion 24 of the ejection assembly 20 are disengaged from each other.

The back-strike spring is wound around the back-strike shaft and is located inside the back-strike turntable 31. The pull rope 32 is wound around the back-strike shaft, and its end passes through the outside of the ejection base 100 and is provided with a pull ring 33.

[0041] When the two ejection assemblies 20 of the power conversion structure of this embodiment are respectively engaged with the adjacent trigger assemblies 50, the conversion push rod 41 is pressed by one of the ejection assemblies 20, and the other end thereof presses the sliding gear 13 away from the ejection assemblies 20, so that the sliding gear 13 and the driving gear 12 are separated from each other. At this time, the pull rope 32 of the driving assembly 30 drives the return shaft to rotate, and reciprocates under the action of the return spring, so that the driving gear 12 can rotate, and the conversion push rod 41 is not pressed by the pull rope 32 of the driving assembly 30. The sliding gear 13 pressed by the driving gear 12 can accelerate the ejection wheel 60 clamped on the ejection assembly 20 through the transmission assembly 101; in addition, the trigger portion 51 is driven by the launching slide block 53 of the sliding trigger assembly 50 to press the trigger spring 52, so that the square block under the trigger portion 51 and the buckle portion of the ejection assembly 20 are disengaged from each other, and the slide portion 22 of the ejection assembly 20 ejects the ejection wheel 60 fixed on the clamping portion 21 under the action of the ejection spring 25.

[0042] Then the conversion push rod 41 loses the pressing force and is reset under the elastic action of the push rod spring 42, so that the isolated sliding gear 13 is matched with the driving gear 12 for transmission connection again.

[0043] Therefore, the power conversion structure of the present invention is cleverly designed. Through the cooperation of the power assembly 10, the ejection assembly 20, the drive assembly 30, the conversion assembly 40 and the trigger assembly 50 arranged on the ejection base 100, the ejection wheel 60 mounted on the ejection assembly 20 can be rotated and accelerated, and the ejection assembly 20 is driven by the trigger assembly 50 to eject the ejection wheel 60, so that the power conversion structure of the present invention not only has the function of ejection; in addition, power conversion acceleration can also be performed through the conversion assembly 40, so that the power conversion structure of the present invention has the function of power conversion, which expands the fun functionality and entertainment of the toy.

When the pull-back turntable 31 rotates, the touch push block presses the touch switch 73 to connect the light circuit, and the plurality of LED lights 71 emit light.

[0048] In order to make the motorcycle shape more realistic, the ejection base 100 of this embodiment is shaped like a motorcycle.

[0049] In the ejection toy of this embodiment, when the two ejection assemblies 20 are respectively engaged with the adjacent trigger assemblies 50, the conversion push rod 41 is pressed by one of the ejection assemblies 20, and its other end presses the sliding gear 13 away from the ejection assembly 20 so that the sliding gear 13 and the driving gear 12 are separated from each other. At this time, the pull rope 32 of the driving assembly 30 drives the return shaft to rotate, and reciprocates under the action of the return spring, so that the driving gear 12 can rotate, and the unconverted push rod 4 The sliding gear 13 that is pressed against the ejection wheel 60 clamped on the ejection assembly 20 can be accelerated through the transmission assembly 101 under the drive of the driving gear 12; in addition, the trigger portion 51 is driven to press the trigger spring 52 through the launching slide block 53 of the sliding trigger assembly 50, so that the square block under the trigger portion 51 and the buckle portion of the ejection assembly 20 are mutually disengaged, and the slideway portion 22 of the ejection assembly 20 ejects the ejection wheel 60 fixed on the clamping portion 21 under the action of the ejection spring 25.

[0050] Then the conversion push rod 41 loses the pressing force and is reset under the elastic action of the push rod spring 42, so that the isolated sliding gear 13 is matched with the driving gear 12 for transmission connection again.

[0051] Therefore, the ejection toy of the present invention not only has the ejection function; in addition, it can also perform power conversion acceleration through the conversion component, so that the ejection toy of the present invention has the power conversion function, which expands the fun functionality and entertainment of the toy.
