[0002] With the improvement of social living standards, consumers have various requirements for toys. Therefore, manufacturers need to follow up in a timely manner and add various functions to toys to meet consumer needs and maintain competitiveness in the market.

[0003] In egg-shaped toys, some manufacturers often set various structures inside the toys to simulate the hatching and breaking of eggs, so as to achieve the effect of eggs breaking out of their shells. For example, a toy hatching egg disclosed in the prior art CN210057396U conveniently uses an elastic device to make the upper and lower shells have elastic force to separate, and at the same time cooperates with hooks and buckles to limit the separation of the upper and lower shells, and switches the connection relationship between the hooks and the buckles through a rotating drive device, so that the elastic device pops open the upper shell. However, this method often requires a complex internal structure, especially in the structure of the rotating drive device and the hooks, and it also uses a motor and a button to drive the rotating drive device, which increases its production cost. In use, egg toys are often more likely to fall from high places such as desktops due to their special shape, so the overly complex structure makes them more susceptible to damage.

[0004] In order to solve the above technical problems, the present invention designs a cracked toy egg. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 , Figure 2 As shown, a cracked toy egg comprises an upper shell, a lower shell, a pop-up assembly and a trigger assembly.

[0023] The upper shell 1 and the lower shell 2 are matched with each other up and down. The lower part of the lower shell 2 has a screwing part 21 that can rotate relatively. The upper shell 1 and the lower shell 2 are provided with a top groove 11 for cooperating with the elastic column 32.

[0024] The ejection assembly 3 includes: a spring 31 and an elastic column 32 . The spring 31 is arranged on the lower housing 2 . The elastic column 32 is connected to the upper part of the spring 31 . A locking notch 321 is arranged on the elastic column 32 .

[0025] A limit block 322 is disposed on the elastic column 32 , a push-up tenon 323 is disposed on the top of the elastic column 32 , and a locking block 324 is disposed on the side of the push-up tenon 323 .

[0026] like Figure 3 As shown, the trigger assembly 4 includes: a driving shaft 41 , a gear set 42 , a clockwork box 43 , a one-way wheel 44 and a lever 45 .

[0027] The drive shaft 41 is connected to the screwing part 21 , and the drive shaft 41 is meshed with the clockwork box 43 through the gear set 42 . The one-way wheel 44 is sleeved on the upper end of the drive shaft 41 , and the lever 45 is swingably installed inside the lower housing 2 .

[0028] Please refer to Figure 4 The lever 45 has an upper locking portion 451 and a lower shifting portion 452. The one-way wheel 44 is provided with a one-way tooth 441. The locking portion 451 can be plugged and matched with the locking notch 321 to limit the elastic column 32 from bouncing upward to push open the upper shell 1.

[0029] When the screwing portion 21 is turned, the driving shaft 41 drives the gear set 42 to wind the clockwork box 43, and the clockwork box 43 outputs and drives the one-way wheel 44 and uses the one-way tooth 441 to move the moving portion 452, and the moving rod 45 swings and causes the locking portion 451 to disengage from the locking notch 321, thereby releasing the spring column 32 to lift the upper shell 1.

[0030] Specifically, the gear set 42 includes a first gear 421 and a second gear 422 . The first gear 421 is coaxially connected to the driving shaft 41 . The second gear 422 is meshedly connected to the first gear 421 and is coaxially connected to the rotating shaft of the clockwork box 43 .

[0031] It should be noted that the clockwork box 43 is a common structure in toy products, and generally has an energy storage structure such as a coil spring inside, which can be wound and then released. This type of structure is generally used in toy cars, especially in the common type of toy cars that can move forward after being pulled back and released. Since the structure is too conventional, it will not be repeated in this solution.

[0032] Please refer to Figure 2 An upper mounting plate 51 and a lower mounting plate 52 are provided inside the lower shell 2, and the upper mounting plate 51 and the lower mounting plate 52 are connected up and down by a latch.

[0033] The clockwork box 43 is arranged between the upper mounting plate 51 and the lower mounting plate 52. The upper mounting plate 51 is provided with a slot 511 for installing the spring 31 and the spring column 32. The lower end of the slot 511 has a through hole facing the lever, so that the locking portion 451 of the lever can penetrate into the locking notch 321 through the through hole.

[0034] A gear mounting position 521 is provided in the middle of the lower mounting plate 52 , and the first gear 421 is installed in the gear mounting position 521 . A rotating shaft pin 522 and a reset shaft pin 523 are provided at the lower end of the lower mounting plate 52 .

[0035] like Figure 4 As shown, the lever 45 is provided with a rotating through hole 453 which can cooperate with the rotating shaft pin 522. The lever 45 is swingably installed inside the lower shell 2 through the rotating shaft pin 522 and the rotating through hole 453. One side of the lever 45 is connected to the reset shaft pin 523 through a reset spring 454, so that the locking portion 451 of the lever 45 has a tendency to be engaged with the locking notch 321.

[0036] like Figure 5As shown in (A), a clutch spring 455 is provided between the lever 45 and the lower mounting plate 52, and the diameter of the rotating through hole 453 is larger than the rotating shaft pin 522, so that the clutch spring 455 can pull the lever 45 to an inclined posture and make the shifting part 452 and the one-way wheel 44 disengage from the transmission relationship.

[0037] like Figure 5 As shown in (B), when the elastic column 32 is pressed downward, the limit block 322 can not only limit the circumferential position of the lever 45, but also straighten the lever 45 so that it is no longer in a tilted posture. At this time, the toggle portion 452 of the lever 45 and the one-way tooth 441 of the one-way wheel 44 resume the meshing transmission relationship again.

[0038] It should be pointed out that one end of the spring 31 is directly fixedly connected to the slot of the upper mounting plate, and when the spring 31 pushes up the spring column and causes the upper shell 1 to pop out, the spring column 32 is tightly inserted into the top groove 11 of the upper shell through the pushing tenon, and is locked and connected through the cooperation of the locking block 324 and the locking hole 12, so that the spring column 32 and the upper shell 1 pop out together.

[0039] Working principle:

[0040] When the upper and lower shells are buckled together, the spring 31 is compressed in the slot 511 , and at the same time, due to the action of the reset spring 454 , the locking portion 451 of the lever 45 is inserted into the locking notch 321 , thereby limiting the spring 31 from restoring and popping the upper shell 1 open.

[0041] When the screwing part 21 is turned, the first gear 421 is driven to move clockwise through the driving shaft 41, and then the clockwork box 43 is wound through the second gear 422 until the energy is stored, and the screwing part 21 is released. The clockwork box 43 drives the first gear 421 to rotate counterclockwise through the second gear 422, and at the same time drives the one-way wheel 44 coaxially connected and arranged on the upper end of the driving shaft 41 to rotate, and then the one-way tooth 441 on the one-way wheel 44 pushes away the pushing part 452 of the lever, and the lever 45 overcomes the elastic force of the reset spring 454 to swing, and the locking part 451 is disengaged from the locking notch 321, and the spring 31 restores its elastic deformation and pushes the upper shell 1 open through the elastic column 32.

[0042] On the one hand, since the one-way wheel 44 is provided with a one-way tooth 441, when the screwing portion 21 is turned to drive the driving shaft 41, although the one-way wheel 44 will also rotate coaxially, it will not mesh with the toggle portion 452. When the clockwork box 43 releases the stored energy, it drives the one-way wheel 44 to rotate in a direction such that the one-way tooth 441 can drive the toggle portion 452.

[0043] On the other hand, the tilting posture of the lever 45 is controlled by the clutch spring 455 and the limit block of the spring column 32, so that a controllable clutch relationship exists between the shifting portion 452 of the lever 45 and the one-way wheel 44, thereby avoiding meshing transmission to the lever 45 when winding the mainspring box 43.

[0044] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical solution of the utility model should be included in the protection scope of the utility model.
