The end of the second conversion gear 43 away from the first conversion gear 42 is provided with a conversion spring, and the conversion spring is used to drive the first conversion gear 42 and the second conversion gear 43 to mesh with each other. Further, the first conversion gear 42 is matched with the driving gear 12 for transmission connection, and the second conversion gear 43 is provided with a circumferential convex ring 45. The conversion push block 44 is provided on the side wall of the ejection assembly 20 close to the first conversion gear 42, and the conversion push block 44 is used to press the circumferential convex ring 45 of the second conversion gear 43 so that the second conversion gear 43 and the first conversion gear 42 are separated from each other.

[0034] In this embodiment, the contact surface between the conversion push block 44 and the circumferential convex ring 45 is a slope structure, whereby the conversion push block 44 is driven by the ejection assembly 20 to press the circumferential convex ring 45 so that the second conversion gear 43 and the first conversion gear 42 are separated from each other; when the conversion push block 44 is driven by the ejection assembly 20 to separate from the circumferential convex ring 45, the second conversion gear 43 re-engages with the first conversion gear 42 under the action of the conversion spring, and at this time, the first conversion gear 42 and the second conversion gear 43 are coaxially rotated, thereby realizing the power conversion function of the power conversion structure of this embodiment.

[0037] Among them, the clamping portion 21 of this embodiment includes a fixed portion 201 and a movable portion 202, and 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 this embodiment, the fixed portion 201 is slidably arranged in the ejection slot of the ejection base 10. When in use, the clamping portion 21 of the ejection assembly 20 of this embodiment is used to clamp and fix the ejection wheel 60. The movable portion 202 twists outward to increase the space of the arc-shaped clamping position.

[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 ejection assembly 20 drives the conversion push block 44 to press the circumferential convex ring 45 so that the second conversion gear 43 and the first conversion gear 42 are separated from each other; when the conversion push block 44 is driven by the ejection assembly 20 to separate from the circumferential convex ring 45, the second conversion gear 43 re-engages with the first conversion gear 42 under the action of the conversion spring, and at this time, the first conversion gear 42 and the second conversion gear 43 are coaxially rotatably arranged; thereby realizing the power conversion function of the power conversion structure of this embodiment.

[0042] 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 driving gear 12 then transfers the kinetic energy to the first conversion gear 42 of the conversion assembly 40, thereby driving the transmission assemblies 203 on the two ejection assemblies 20 to rotate respectively through the conversion assembly 40.

[0043] Compared with the prior art, the power conversion structure of the present invention is cleverly designed.

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] When the two ejection assemblies 20 of the ejection toy of the present embodiment are respectively engaged with the adjacent trigger assemblies 50, the ejection assembly 20 drives the conversion push block 44 to press the circumferential convex ring 45 so that the second conversion gear 43 and the first conversion gear 42 are separated from each other; when the conversion push block 44 is driven by the ejection assembly 20 to separate from the circumferential convex ring 45, the second conversion gear 43 is re-engaged with the first conversion gear 42 under the action of the conversion spring, and at this time, the first conversion gear 42 and the second conversion gear 43 are coaxially rotatably arranged; thereby realizing the power conversion function of the present embodiment.

[0050] The pull rope 32 of the driving assembly 30 drives the pull-back shaft to rotate, and reciprocates under the action of the pull-back spring, so that the driving gear 12 can rotate, and the driving gear 12 then transmits the kinetic energy to the first conversion gear 42 of the conversion assembly 40, thereby driving the transmission assemblies 203 on the two ejection assemblies 20 to rotate respectively through the conversion assembly 40, and finally driving the rotation of the ejection wheel 60, and the ejection assembly 20 can be disengaged and separated from the trigger assembly 50 by driving the trigger assembly 50, and the ejection wheel 60 is ejected.

[0051] The ejection toy of the present invention not only has the ejection function, but also can perform power conversion acceleration through the conversion component 40, so that the ejection toy of the present invention has the power conversion function, which expands the fun functionality and entertainment of the toy.

[0052] Example 3

[0053] This embodiment is basically the same as the second embodiment. This embodiment provides a projectile toy. The difference between the projectile toy and the second embodiment is that:

[0054] The power assembly 10 also includes two sliding gears 13 arranged on the power base 11, the two sliding gears 13 are respectively connected to the driving gear 12 in transmission, and the two sliding gears 13 are slidably arranged on the power base 11; specifically, two sliding grooves 14 are respectively arranged on the power base 11 at intervals, and the two sliding gears 13 are respectively slidably arranged in the corresponding sliding grooves 14, and the driving gear 12 is located between the two sliding gears 13 and is respectively movably meshed with the two sliding gears 13.

[0055] In this embodiment, an ejection mechanism 80, a trigger mechanism 90 and an ejection wheel 60 are further provided on the side of the driving gear 12 away from the two ejection assemblies 20, wherein the ejection wheel 60 is rotatably arranged in the ejection mechanism 80, and is transmission-connected with the ejection mechanism 80 through a transmission gear set 102, and the ejection mechanism 80 and the trigger mechanism 90 are engaged and clamped.

[0056] Among the two sliding gears 13 , the sliding gear 13 close to the conversion assembly 40 is arranged between the driving gear 12 and the first conversion gear 42 , and the sliding gear 13 far from the conversion assembly 40 is arranged between the driving gear 12 and the transmission gear set 102 .

[0057] The power base 11 further includes a conversion push rod 15 and a push rod spring 16. The conversion push rod 15 is telescopically arranged on the power base 11 through the push rod spring 16. One end of the conversion push rod 15 abuts against an ejection assembly 20 on one side of the driving gear 12, and the other end thereof abuts against one of the sliding gears 13. Therefore, when the ejection assembly 20 presses the conversion push rod 15, the conversion push rod 15 presses against one of the sliding gears 13, and the sliding gear 13 is temporarily separated from the driving gear 12, so that the ejection mechanism 80 close to the sliding gear 13 temporarily loses the power source, and the ejection wheel 60 therein cannot be accelerated.

[0058] Therefore, the ejection toy of this embodiment can adjust the power conversion on both sides of the driving gear 12 through the conversion push rod 15, and can adjust the power conversion on the same side of the driving gear through the conversion assembly 40, further expanding the functionality and entertainment of the toy.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the power conversion structure of the invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
