Detailed implementation manners

[0054] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0056] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0057] Referring to Figures 1 to 9 As shown, an embodiment of the present application provides a gyro toy, which includes a holding shell 1, an inertial component 2, an acceleration gear set 3, and a rotary drive shell 4. The inertial component 2 is rotatably arranged in the holding shell 1, and the inertial component 2 has a support shaft 21. The acceleration gear set 3 is arranged in the holding shell 1, and the acceleration gear set 3 is in transmission cooperation with the inertial component 2. The rotary drive shell 4 is rotatably sleeved on the inertial component 2, and the rotary drive shell 4 is in transmission cooperation with the acceleration gear set 3. Under the action of an external force, the rotary drive shell 4 can rotate, and the inertial component 2 is driven to rotate through the acceleration gear set 3.

[0058] When playing with the gyro toy provided by the embodiment of the present application, hold the holding shell 1 and friction the rotary drive shell 4 to make the rotary drive shell rotate relative to the holding shell 1. The rotary drive shell 4 drives the acceleration gear to rotate. The acceleration gear increases the rotation speed of the rotary drive shell 4, and then transmits the increased rotation speed to the inertial component 2, so that the inertial component 2 rotates at a high speed. Then, place the gyro toy on a support surface. Under the continuous action of the rotation force released by the inertial component 2, the rotation duration can be greatly improved and the rotation can be kept stable.

[0059] Wherein, one end of the support shaft 21 is connected to a counterweight, and the other end passes through the rotary drive shell 4 to form the tip of the gyro. The rotation of the inertial component 2 can drive all positions of the gyro including the tip, which can ensure the stable rotation of the gyro.

[0060] In some possible implementation schemes, referring to Figure 4 As shown, the rotary drive shell 4 has an internal gear ring 41, and the inertial component 2 has a driving gear 22. The internal gear ring 41 is meshed with the input gear 31 of the acceleration gear set 3, and the output gear 32 of the acceleration gear set 3 is meshed with the driving gear 22. When the rotary drive shell 4 rotates, the internal gear ring 41 rotates, the internal gear ring 41 drives the acceleration gear set 3 to rotate, and the acceleration gear set 3 drives the inertial component 2 to rotate through the driving gear 22.

[0061] Wherein, the driving gear 22 is sleeved on the support shaft 21, and the driving gear 22 is in interference fit and / or ultrasonic welding with the support shaft 21, and the two are synchronous rotating parts.

[0062] In some possible embodiments, referring to Figure 4 As shown, the gyro toy further includes a plurality of acceleration gear sets 3, and each of the acceleration gear sets 3 is sequentially arranged circumferentially around the inertial assembly 2. The input end gears of each of the acceleration gear sets 3 are all meshed with the internal tooth ring 41, and the output end gears of each of the acceleration gear sets 3 are all meshed with the driving gear 22.

[0063] Setting a plurality of acceleration gear sets 3 can improve the transmission stability from the rotary drive housing 4 to the acceleration gear sets 3 and then to the inertial assembly 2, and the plurality of acceleration gear sets 3 are evenly arranged circumferentially around the inertial assembly 2. In this way, the weight of the gyro toy plus the gear sets in one week is also evenly distributed, making the gyro rotate more smoothly.

[0064] In some possible embodiments, referring to Figure 6 As shown, a plurality of arc-shaped grooves 11 are circumferentially spaced on the holding shell 1 around the inertial assembly 2, and the output end gears of each of the acceleration gear sets 3 are respectively slidably connected in the corresponding arc-shaped grooves 11. During the process of the rotary drive housing 4 rotating in the first direction, each output gear 32 slides to one end of the arc-shaped groove 11, and the output gears 32 are respectively meshed with the input gear 31 and the driving gear 22. During the process of the rotary drive housing 4 rotating in the second direction, each output gear 32 slides to the other end of the arc-shaped groove 11, and the output gears 32 are separated from the driving gear 22. In this way, the inertial assembly 2 will only rotate in one direction, and there will be no reverse force applied to the driving gear 22 when the inertial assembly 2 rotates at a high speed, and the gears will not be damaged for this reason, ensuring the service life of the gyro.

[0065] In some possible embodiments, referring to Figure 5 As shown, the holding shell 1 has a cavity, and the inertial assembly 2 includes a counterweight, and the counterweight is located in the cavity and sleeved on the support shaft 21. The counterweight can increase the inertia of the inertial assembly 2, thereby achieving the effects of prolonging the rotation time of the gyro and improving the rotation stability of the gyro.

[0066] The counterweight is in interference fit and / or ultrasonic welded with the support shaft 21, and the counterweight, the driving gear 22 and the support are synchronous rotating parts.

[0067] In some possible embodiments, the counterweight includes a housing 23, the housing 23 has an inner cavity, and a plurality of counterweight blocks are arranged in the inner cavity, and each of the counterweight blocks is sequentially arranged circumferentially around the support shaft 21. The housing 23 can be made of plastic material, and the housing 23 is in interference fit and / or ultrasonic welded with the support shaft 21. The counterweight blocks can be made of metal material, with large weight and small volume. The counterweight blocks are evenly distributed around the support shaft 21 to ensure uniform weight distribution and stable rotation. The counterweight blocks are not shown in the figure.

[0068] In some possible embodiments, the housing 23 has an upper housing 231 and a lower housing 232. The upper housing 231 and the lower housing 232 are snapped together, and the upper housing 231 and the lower housing 232 enclose an inner cavity. The upper housing 231 and the lower housing 232 are sleeved on the support shaft 21. A plurality of through holes 233 are provided on both the upper housing 231 and the lower housing 232. The through holes 233 on the upper housing 231 and the lower housing 232 are sequentially arranged at intervals around the circumference of the support shaft 21. Each counterweight is located in the inner cavity, and the counterweights are respectively limited in two opposite through holes 233 on the upper housing 231 and the lower housing 232. The cooperation of two opposite through holes 233 up and down can limit the counterweights, ensuring the stable position of the counterweights, and thus ensuring uniform weight distribution around the support shaft 21.

[0069] Among them, the counterweight can be spherical or quasi-spherical, so that it is easier to be stably limited by two opposite through holes 233.

[0070] Among them, the upper housing 231 and the lower housing 232 are in interference fit and / or ultrasonic welded with the support shaft 21.

[0071] In some possible embodiments, as shown in Figures 1 to 7 As shown, a friction ring 5 is sleeved on the rotary drive housing 4. The friction ring 5 protrudes from the surface of the rotary drive housing 4, and the friction ring 5 is a flexible member. The friction ring 5 can increase the friction force between the rotary drive housing 4 and the friction surface, so that the rotary drive housing 4 can be smoothly rotated by sliding the rotary drive housing 4 along the friction surface.

[0072] In some possible embodiments, the rotary drive housing 4 is rotatably sleeved on one side of the holding housing 1. An annular groove 12 is provided on the outer surface of the rotary drive housing 4 close to the holding housing 1, and the friction ring 5 is sleeved in the annular groove 12. The annular groove 12 can limit the friction ring 5 to ensure that the friction ring 5 will not easily fall off.

[0073] In some possible embodiments, the holding housing 1 has a support cylinder 13, and a limiting sleeve 6 is fixedly sleeved on the support cylinder 13. The rotary drive housing 4 is rotatably sleeved on the limiting sleeve 6. The limiting sleeve 6 restricts the rotary drive housing 4 from moving away from the holding housing 1 along the support cylinder 13. The support shaft 21 passes through the support cylinder 13, and the support shaft 21 can rotate relative to the support cylinder 13. The rotary drive housing 4 is limited between the limiting sleeve 6 and the holding housing body 15, which not only ensures the stable installation of the rotary drive housing 4, but also does not affect the rotation of the rotary drive housing 4 relative to the holding housing 1.

[0074] Among them, the support cylinder 13 and the limiting sleeve 6 are in interference fit and / or ultrasonic welded.

[0075] In some possible implementation schemes, a limiting cylinder 14 is provided on the side of the holding shell 1 facing away from the supporting cylinder 13, one end of the supporting shaft 21 is inserted into the limiting cylinder 14, and the other end extends to the supporting cylinder 13 and penetrates the supporting cylinder 13 to form a top.

The preferred embodiments do not describe all the details in detail, nor do they limit the present application to the specific implementation methods described.
