Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to an egg-bursting toy. Background Technology

[0002] Eggshell toys have long been popular with children as a fun toy. However, most eggshell toys on the market today consist of two halves of an eggshell. The toy is placed inside the two halves and then glued together with tape or glue to form a complete eggshell. Children can only take out the two glued halves by separating them, which lacks fun. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide an egg-bursting toy that produces a dynamic egg-bursting effect, offering better visual appeal, greater fun, and helping to stimulate children's intelligence. The technical solution adopted is as follows:

[0004] An egg-bursting toy includes a detachably connected lower eggshell assembly and an upper eggshell assembly. The lower eggshell assembly comprises a first housing, a first support member, and a first insertion post. The first support member is installed inside the first housing, and the lower end of the first insertion post is fixedly installed on the first support member. A snap-fit ​​groove is provided on the side wall of the first insertion post. The upper eggshell assembly comprises a second housing, a third housing, a second support member, a first insertion tube, a first spring, a swing arm, and a swing drive mechanism for driving the swing arm to swing laterally about its first end. The second support member is installed inside the second housing, and the first insertion tube extends along its upper and lower sides... The first spring is disposed on the second support member, and the upper end of the first spring is connected to the top end of the first insertion tube. The upper middle part of the first insertion post can be inserted into the first insertion tube through the lower end opening of the first insertion tube, and the upper end of the first insertion post is in close contact with the lower end of the first spring. The swing drive mechanism is mounted on the second support member, and the first end of the swing arm is rotatably mounted on the second support member. The middle part of the swing arm is provided with a snap-fit ​​block that can engage with the snap-fit ​​groove. The third housing is disposed on the upper side of the second housing. The first housing, the second housing, and the third housing are assembled from bottom to top to form an egg-shaped shell.

[0005] When assembling the egg-bursting toy, the upper middle part of the first insertion post is inserted into the lower opening of the first insertion tube (at this time, the first spring is compressed under the pressure of the upper end of the first insertion post). The swing arm is then driven by a swing drive mechanism to swing laterally around its first end toward the first insertion post, causing the locking block on the swing arm to engage with the locking groove, thus limiting the first insertion post. This allows the upper edge of the first shell to fit against the lower edge of the second shell, allowing the first, second, and third shells to be assembled sequentially from bottom to top to form an egg-shaped outer shell. When the egg-bursting toy needs to automatically burst, the swing drive mechanism drives the swing arm to swing laterally around its first end away from the first insertion post, causing the locking block to disengage from the locking groove. At this time, the first insertion post automatically pops out from the first insertion tube under the action of the first spring, causing the lower eggshell assembly to quickly separate from the upper eggshell assembly. This creates a dynamic egg-bursting effect, providing a better visual experience, increased fun, and helping to stimulate children's intelligence.

[0006] In a preferred embodiment of this invention, the second support member is provided with a vertically oriented support column, and the first end of the swing arm is provided with a support ring. The swing arm is rotatably sleeved on the support column through the support ring. With this structure, the swing arm can swing freely in the lateral direction around the support column by utilizing the cooperation between the support ring and the support column.

[0007] As a preferred embodiment of this utility model, the swing drive mechanism includes a first rotating shaft, a second rotating shaft, a third rotating shaft, a spring energy storage mechanism, a cam, and a second spring. The first, second, and third rotating shafts are all rotatably mounted on a second support member and are arranged vertically. The second, third, and first rotating shafts are connected by a transmission mechanism. The spring energy storage mechanism is mounted on the second support member, and its power input and output ends are connected to the second rotating shaft. The first and second ends of the second spring are respectively connected to the second support member and the second end of the swing arm. The cam is mounted on the third rotating shaft, and the second end of the swing arm is provided with a cam follower block, which contacts and engages with the contour of the cam. The third housing is rotatably mounted on the upper side of the second housing and is connected to the upper end of the first rotating shaft.

[0008] When assembling the egg-bursting toy, the upper middle part of the first insertion post can be inserted into the first insertion tube through the lower end opening. During this process, under the tension of the second spring, the cam follower block at the second end of the swing arm and the cam profile always maintain contact and engagement. At the same time, the locking block on the swing arm is close to the upper side wall of the first insertion post and tends to move towards the first insertion post. Until the locking groove on the first insertion post reaches the position corresponding to the locking block on the swing arm, the locking block on the swing arm will automatically enter the locking groove and engage with the locking groove, thereby limiting the first insertion post. Thus, the first shell, the second shell, and the third shell can be assembled from bottom to top to form an egg-shaped outer shell. When the egg-bursting toy needs to automatically burst open, the third housing can be rotated to drive the first shaft to rotate, and then the transmission mechanism can drive the second and third shafts to rotate together. The rotating second shaft stores energy for the spring-loaded energy storage mechanism. Subsequently, the egg-bursting toy can be placed on a flat surface, and the spring-loaded energy storage mechanism can drive the second shaft to rotate continuously. Through the transmission mechanism and the first shaft, the third shaft and the cam can rotate continuously. By utilizing the cooperation between the cam follower block and the cam profile, the swing arm can be driven to swing laterally around its first end away from the first insertion post, so that the locking block disengages from the locking groove. At this time, the first insertion post automatically pops out from the first insertion tube under the action of the first spring, so that the lower eggshell assembly and the upper eggshell assembly automatically burst open, thereby producing the dynamic effect of automatic egg bursting.

[0009] The aforementioned clockwork energy storage mechanism can adopt existing conventional structures. Its structure and working principle can be found in Chinese utility model patent with publication number CN205955402U, entitled "A Remote Monitoring Device for a Mechanically Powered Anti-theft Door", or Chinese utility model patent with publication number CN102661374A, entitled "A Release Device for a Clockwork Energy Storage Mechanism". These are existing technologies and will not be described in detail here.

[0010] As a further preferred embodiment of this utility model, the transmission mechanism includes a transmission shaft, a first gear, a second gear, a third gear, a fourth gear, and a fifth gear. The transmission shaft is rotatably mounted on the second support member and runs vertically. The first gear is fixedly mounted on the first rotating shaft, the second and third gears are fixedly mounted on the transmission shaft, the fourth gear is fixedly mounted on the second rotating shaft, and the fifth gear is fixedly mounted on the third rotating shaft. The second gear meshes with the first gear, the fourth gear meshes with the third gear, and the fifth gear meshes with the first gear. When the popping toy needs to automatically pop, the first rotating shaft can be rotated by rotating the third housing. This rotation, in turn, drives the transmission shaft and the third gear to rotate via the first and second gears, and then drives the second rotating shaft to rotate via the fourth gear. The rotating second rotating shaft stores energy for the spring-loaded energy storage mechanism. Subsequently, the spring-loaded energy storage mechanism drives the second rotating shaft and the fourth gear to rotate continuously, which in turn drives the transmission shaft and the second gear to rotate via the third gear, and then drives the third rotating shaft and the cam to rotate continuously via the first and fifth gears.

[0011] As a further preferred embodiment of the present invention, the second support member includes a lower support frame and an upper support frame, with the upper support frame disposed above the lower support frame; the lower and upper ends of the first rotating shaft, the second rotating shaft, the third rotating shaft and the transmission shaft are rotatably connected to the lower support frame and the upper support frame, respectively; the first insertion tube and the spring energy storage mechanism are both fixedly installed on the lower support frame; and the first end of the second spring is connected to the lower support frame.

[0012] As a further preferred embodiment of this utility model, the cam is mounted on the third rotating shaft via a sleeve, the sleeve being fitted onto the middle section of the third rotating shaft, and the cam being fixedly connected to the sleeve. With this structure, the sleeve rotates under the drive of the third rotating shaft, thereby causing the cam to rotate continuously.

[0013] As a further preferred embodiment of this utility model, the third housing is connected to the upper end of the first rotating shaft via a detachable connection structure. The detachable connection structure includes a second insertion post and a second insertion tube. The upper end of the second insertion tube is connected to the inner wall of the third housing, and the lower end of the second insertion post is connected to the upper end of the first rotating shaft. The upper end of the second insertion post can be inserted into the second insertion tube through the lower opening of the second insertion tube, and the upper end of the second insertion post matches the inner wall of the second insertion tube. Specifically, the cross-sectional shape of the second insertion post and the second insertion tube can be any shape other than a circle or an arc, such as a regular polygon, trapezoid, or irregular shape. When the third housing is rotated, the second insertion post and the second insertion tube can transmit power to the first rotating shaft to cause it to rotate.

[0014] As a preferred embodiment of this utility model, the side wall of the first insertion tube is provided with a notch for inserting the snap-fit ​​block. With this structure, the snap-fit ​​block can be inserted into the inner side of the first insertion tube through the notch and engage with the snap-fit ​​groove.

[0015] As a preferred embodiment of this utility model, the upper edge of the first shell and the lower edge of the second shell are both wavy, and the upper edge of the first shell matches the lower edge of the second shell. This makes it easier to assemble the first and second shells and ensures that the assembled egg-shaped shell is more aesthetically pleasing.

[0031] The following is a brief description of how to use this egg-bursting toy:

[0032] When assembling the popping toy, the upper middle part of the first insertion post 13 can be inserted into the lower end opening of the first insertion tube 24 (at this time, the first spring 25 is compressed under the pressure of the upper end of the first insertion post 13). During this process, under the pulling force of the second spring 276, the cam follower block 261 at the second end of the swing arm 26 and the contour of the cam 275 always maintain contact and engagement. At the same time, the locking block 260 on the swing arm 26 is in close contact with the upper side wall of the first insertion post 13 and has an orientation towards the first... The insertion post 13 moves until the locking groove 131 on the first insertion post 13 reaches the position corresponding to the locking block 260 on the swing arm 26. At this point, the locking block 260 on the swing arm 26 will automatically enter the locking groove 131 and engage with it, thereby limiting the first insertion post 13. This allows the upper edge of the first housing 11 to fit against the lower edge of the second housing 21, thus enabling the first housing 11, the second housing 21, and the third housing 22 to be sequentially combined from bottom to top to form an egg-shaped outer shell 100.

[0033] When the egg-bursting toy needs to automatically burst open, the first rotating shaft 271 can be rotated by rotating the third housing 22. Then, the second rotating shaft 272 and the third rotating shaft 273 can be rotated together by the transmission mechanism 277. The rotating second rotating shaft 272 stores energy for the spring-loaded energy storage mechanism 274. Subsequently, the egg-bursting toy can be placed on a flat surface. The spring-loaded energy storage mechanism 274 drives the second rotating shaft 272 to rotate continuously. The transmission mechanism 277 and the first rotating shaft 271 drive the third rotating shaft 273 and the cam 275 to rotate continuously. By utilizing the cooperation between the contour of the cam follower block 261 and the cam 275, the swing arm 26 is driven to swing laterally around its first end away from the first insertion post 13, so that the locking block 260 disengages from the locking groove 131. At this time, the first insertion post 13 automatically pops out from the first insertion tube 24 under the action of the first spring 25, so that the lower eggshell assembly 1 and the upper eggshell assembly 2 automatically burst open, thereby producing an automatic egg-bursting dynamic effect. The visual effect is better, the fun is stronger, and it helps to stimulate children's intelligence.
