In addition, the rotary chess piece of the embodiment can also be independently used as a child game toy, and the hand operation capability and the color distinguishing capability of a child can be exercised through the rotary color change of the rotary chess piece.

The structure of the rotating chessman and the rotating color changing principle thereof of the present embodiment will be specifically described below with reference to fig. 1 to 7.

The rotary chess pieces comprise a plurality of double-head bevel gears 1, a support frame 2, a transparent shell 3 and magnetic rods.

A plurality of double-end bevel gears 1 are sequentially meshed to form a closed transmission gear set, and any one of the double-end bevel gears 1 is rotated to drive the rest double-end bevel gears 1 to synchronously rotate. Alternatively, as shown in fig. 1, for example, the number of the plurality of double-ended bevel gears 1 (the teeth of the double-ended bevel gears are not shown for the sake of viewing, and the structure of a specific double-ended bevel gear may be shown in fig. 4) may be 12, 12 double-ended bevel gears 1 are sequentially engaged, and the ends of adjacent double-ended bevel gears 1 correspond to form a closed transmission gear set. Different color parts are sequentially formed on each double-end bevel gear 1 along the peripheral direction of the double-end bevel gear, when the rotary chess piece is used as a go chess piece, the rotary chess piece needs to realize the transformation of three colors, including black, white and intermediate colors, wherein the black and the white are used as chess piece display colors, and the intermediate color is used as a non-interference color. When the rotary chess pieces are independently used as the children game toy, the rotary chess pieces can be formed into various colors, and the number of the colors is not limited, so that the color distinguishing and recognizing ability of children is exercised.

In this embodiment, the color configuration of the rotating chess pieces when the rotating chess pieces are used as weiqi chess pieces is taken as an example, and the color configuration forming mode of the rotating chess pieces is described. The double-end bevel gear 1 of the rotary chess piece is sequentially provided with a first color part (black), a second color part (white) and a third color part (orange for example) along the outer axial direction thereof, the first color part, the second color part and the third color part occupy the same area of the double-end bevel gear 1, and the parts corresponding to the same color on any two adjacent double-end bevel gears 1 can be correspondingly meshed, so that when the double-end bevel gear 1 is rotated, each rotating rotary chess piece rotates by 120 degrees, the surface of the rotary chess piece facing to the outer side can present one color, and the color of the rotary chess piece can be changed by rotating the rotary chess piece.

Referring to fig. 4, the double-ended bevel gear 1 of the present embodiment includes a first straight-tooth bevel gear part 11 and a second straight-tooth bevel gear part 12 which are symmetrically disposed, the first straight-tooth bevel gear part 11 and the second straight-tooth bevel gear part 12 have the same parameters, and the tops of the first straight-tooth bevel gear part and the second straight-tooth bevel gear part 12 are disposed back to back, and are connected by a same rotating shaft 14, and a certain gap is formed between the first straight-tooth bevel gear part and the second straight-tooth bevel gear part.

Referring to fig. 1 and 2, teeth of a plurality of double-ended bevel gears 1 of the rotating chess pieces are sequentially engaged, ends of the double-ended bevel gears 1 correspond, and the double-ended bevel gears 1 are enclosed to form an accommodating space for accommodating a support frame 2.

Referring to fig. 3, the supporting stand 2 includes a supporting body 21, a plurality of first supporting bars 22 and a plurality of second supporting bars 23 provided on the supporting body 21. The supporting body 21 is located in the accommodating space, first ends of the plurality of first supporting rods 22 are connected to the supporting body 21, and second ends of the plurality of first supporting rods 22 extend out of the accommodating space and are supported at ends of the double-ended bevel gear 1. The second end of the first support rod 22 is formed with a plurality of limiting grooves 221 along the circumferential direction thereof, taking the number of the double-ended bevel gears 1 as 12 as an example, the end portions of the 4 double-ended bevel gears 1 are corresponding, the number of the first support rod 22 is 6, taking the placement angle of the rotating chess pieces shown in fig. 2 as an example, the 6 first support rods 22 extend in 6 directions up, down, left, right, front and back respectively, and the second end of each first support rod 22 is formed with 4 limiting grooves 221 at equal intervals along the circumferential direction thereof, the double-ended bevel gears 1 extend into the limiting grooves 221 in a one-to-one correspondence manner through the end portions of the rotating shafts 14 arranged along the axial direction thereof, so that the double-ended bevel gears 1 rotate relative to the first support rods 22 to ensure stable rotation of the plurality of double-ended bevel gears 1, and the support body 21 and the first support rods 22 provide stable support for the double-ended.

A first end of the second support rod 23 is connected to the support body 21, a second end of the second support rod 23 passes through the relief groove 13 between the first straight-tooth bevel gear part 11 and the second straight-tooth bevel gear part 12 of the double-tooth bevel gear 1 and extends out of the accommodating space, and a second end of the second support rod 23 is used for supporting the transparent shell 3. Use double-end bevel gear 1's quantity to be 12 as an example, the groove 13 of dodging of every 3 double-end bevel gear 1 sets up relatively, 3 double-end bevel gear 1's of every promptly dodge the groove 13 and enclose and establish into an dodge space, consequently the quantity of second bracing piece 23 can set up to 8, 8 second bracing pieces 23 one-to-one pass dodge the space in order to support transparent casing 3.

Referring to fig. 6, the transparent shell 3 is covered outside the double-ended bevel gear 1, and the transparent shell 3 is used for providing a protection effect for the rotating chessmen, so as to prevent impurities such as dust, stones and the like from entering the meshing connection of the double-ended bevel gear 1 to affect the normal rotation of the rotating chessmen. The transparent shell 3 is made of transparent material such as organic glass, and the shape of the transparent shell is matched with the outer contour of the double-ended bevel gear 1 of the rotating chessman. The transparent shell 3 may completely cover the plurality of double-ended bevel gears 1 or a part of the plurality of double-ended bevel gears 1 is exposed outside the transparent shell 3, i.e. the rotating chess piece of the present embodiment may be fully exposed, partially exposed or fully enclosed.

When the transparent case 3 completely covers the plurality of double-headed bevel gears 1, the rotation of the double-headed bevel gears 1 can be achieved by means of magnetic rods. Specifically, at least part of double-end bevel gear 1 has the ferromagnetism, can produce the magnetic force effect with the part that has the ferromagnetism of double-end bevel gear 1 when the magnetic rod is attached in transparent casing 3's outside to rotate through magnetic rod drive double-end bevel gear 1, and then drive whole rotatory piece and rotate. It should be noted that the double-ended bevel gear 1 may have a magnetic member embedded therein or the entire double-ended bevel gear 1 may be formed of a material having ferromagnetism, so that at least a portion of the double-ended bevel gear 1 has ferromagnetism.

Furthermore, when the parts of the plurality of double-ended bevel gears 1 are exposed outside the transparent housing 3, as shown in fig. 6, the rotating chess pieces can be rotated by rotating the parts of the double-ended bevel gears 1 exposed outside the housing, and in this case, the rotating chess pieces can be manually rotated without using other tools (such as magnetic bars). Alternatively, as shown in fig. 3, a notch 31 is formed at a position of the transparent shell 3 corresponding to one end of the double-ended bevel gear 1, such that one end of the double-ended bevel gear 1 is exposed to the notch 31, and thus the double-ended bevel gear 1 can be rotated through the notch 31, thereby rotating the chess pieces.

In addition, since the rotating chess piece of the present embodiment needs to change the color by rotating, in order to ensure that the color presented on the surface of the rotating chess piece facing to the outside after rotating is consistent, that is, the rotating chess piece is rotated to the proper position during color change, the rotating chess piece of the present embodiment is further provided with a driving member, and when no external rotating force is applied, the driving member can drive the rotating chess piece to rotate to the locking position, so as to ensure that the color presented on the surface of the rotating chess piece facing to the outside after rotating is consistent. Specifically, as shown in fig. 7, the driving member of the present embodiment is an elastic member 25, the rotating shafts 14 of two opposite double-ended bevel gears 1 in the plurality of double-ended bevel gears 1 are parallel, a passage 211 penetrating the supporting body 21 along a first direction is formed on the supporting body 21, wherein the first direction is perpendicular to any two parallel rotating shafts 14, the elastic member 25 is located in the passage 211, and both ends of the elastic member 25 extend out of the passage 211 and respectively extend between the first straight-tooth bevel gear part 11 and the second straight-tooth bevel gear part 12 of the two opposite double-ended bevel gears 1. Curved recesses are respectively formed on the end surfaces perpendicular to the axis of a pair of two opposite double-headed bevel gears 1 of the plurality of double-headed bevel gears 1 (i.e., between the first straight-toothed bevel gear part 11 and the second straight-toothed bevel gear part 12) (i.e., on the end surface of the first straight-toothed bevel gear part 11 or the end surface of the second straight-toothed bevel gear part 12), one end of an elastic member 25 is coupled to the curved recess of one of the two opposite double-headed bevel gears 1 through a positioning member 24, the other end of the elastic member 25 is coupled to the curved groove of the other double-ended bevel gear 1 of the two double-ended bevel gears 1 facing each other by a positioning member 24, the positioning member 24 may be a positioning member 24 such as a positioning hook, the double-head bevel gear 1 can move along with the curved groove at the end part of the elastic piece 25 in the process of rotating by externally rotating the double-head bevel gear, and the elastic piece 25 is stretched; when the external force acting on the double-ended bevel gear 1 is removed, the double-ended bevel gear 1 can be driven to rotate under the action of the restoring force of the elastic piece 25, so that the elastic piece 25 is restored to the position before stretching, namely, the distance between the two ends of the elastic piece 25 is minimum, namely, the balance position of the rotating chessman is also obtained. During the rotation, the movement trace of the end of the elastic element 25 is the curve of the curved groove. Optionally, the resilient member 25 is a spring.

In the embodiment, three-color equal color change of the rotating chess pieces is taken as an example, and a control curve of the curved groove of the double-head bevel gear is specifically explained. As shown in fig. 5, the control curve of the curved groove satisfies:

wherein a is the friction coefficient of the contact point of the elastic piece and the curved groove;

b is the coefficient of friction between the resilient member and the channel;

c is the friction coefficient between the rotating shaft of the double-ended bevel gear and the first supporting rod;

rho is the radial direction from the contact point of the elastic piece and the curved groove to the corresponding axis of the rotating shaft;

ρ_athe radial direction between the contact point of the elastic piece and the curved groove and the corresponding axis of the rotating shaft when the contact point is a turning point;

r is the radius of the rotating shaft;

alpha is an included angle between a tangent line of the curved groove and the radial direction;

x is the elastic expansion amount of the elastic piece;

λ is the elastic coefficient of the elastic member.

The derivation and calculation process of the control curve of the curved groove of the double-ended bevel gear of the present embodiment will be specifically described below with reference to fig. 8 to 14.

As shown in fig. 8 to 10, assuming that the system formed by the double-ended bevel gear is Q and the elastic member is P, the resisting moment to be overcome if the system Q is rotated without the elastic member is M.

When the spring P is provided, the spring P generates a spring force E, causing the system Q to rotate in a counter-clockwise direction.

Assuming that the action point of the elastic part P and the curved groove is a set point, B is a positive pressure of an elastic force E at the set point in a radial direction perpendicular to the curved groove, the friction force of the elastic part P at the set point is Bb, and alpha is an included angle between a tangent line of the set point and the radial direction of the curved groove; a is the positive pressure between the elastic part and the channel, and Aa is the friction between the elastic part and the channel; c is the positive pressure of the rotating shaft on the system Q, and Cc is the friction force between the rotating shaft and the system Q.

At the set point, the stress of the elastic part in the y-axis direction is as follows: e ═ Bsin α + Aa + Bbcos α; the stress of the elastic part in the x-axis direction is as follows: bcos α ═ a + Bbsin α;

the stress of the system Q in the y-axis direction is as follows: bsin α + Bbcos α;

the torque experienced by system Q is: b ρ cos α ═ Bb ρ sin α + Ccr + M;
