[0002] A worm-like toy is a toy that mimics the movement of a worm. They are usually made up of multiple connected segments, each of which can bend and twist relatively independently to simulate the movement of a worm. This design allows worm-like toys to crawl, twist and bend on a flat surface like a real worm.

[0003] Worm-type toys can vary in appearance and shape, but they generally share some common features. They are generally made of soft materials, such as rubber or plastic, so that they can bend and twist freely. Each segment usually has a pair of connection points, allowing them to connect with adjacent segments and move freely at the connection points.

[0004] The movement of a worm-like toy is usually achieved through manual operation or a built-in mechanism. For example, some worm-like toys may be equipped with a handle or button that can be manually operated to control the movement of the worm. Other worm-like toys may have a simple built-in mechanism that simulates the movement of the worm when the user pushes or rotates the toy.

[0005] Worm-like toys are very popular in the children's toy market because they are uniquely dynamic and interesting. Not only do they provide entertainment and play fun, they also stimulate children's imagination and creativity. In addition, worm-like toys can be used as educational tools to help children learn basic concepts about animal movement and form.

[0032] Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0033] like Figures 1 to 8 As shown, the utility model provides a preferred embodiment of a worm-type structure toy.

[0034] A worm-type structure toy includes a moving mechanism 100, a support frame 200 and a shell 300. The support frame 200 is connected to the moving mechanism 100. The shell 300 includes a worm tail 310. The worm tail 310 is spaced to form a plurality of telescopic sections 311 with telescopic function. One end of the worm tail 310 can be detachably connected to the support frame 200.

[0035] The moving mechanism 100 is used to provide movement and power to enable the toy to move, and the moving mechanism 100 may include a base 110, a driving unit 120, a driving wheel 130, and an auxiliary steering wheel 140. The support frame 200 is connected to the moving mechanism 100, and may be a fixed setting or a movable setting. The main function is to provide a stable support and a fixed position for the worm tail 310 so that the worm tail 310 can be disassembled and installed. The worm tail 310 is a detachable part that can be installed on the support frame 200. The worm tail 310 is the external covering of the worm-type structure toy, and its appearance is not limited. However, the worm in the worm tail 310 refers to a worm-like shape, that is, the concave and convex structures on the worm tail 310 are arranged at intervals to form a plurality of telescopic joints 311 with telescopic function. When one end of the worm tail 310 is dragged, the other end generally generates friction with the ground. During the process of relative stillness caused by friction with the ground, each telescopic joint 311 retracts and extends reciprocatingly with each other, which increases the variation and flexibility of the toy, and increases the fun and simulation of the toy.

[0036] Among them, reference 7 and Figure 8The driving unit 120 is arranged on the base 110 and drives two driving wheels 130 to move. The driving wheels 130 and the auxiliary steering wheels 140 are both extended out of the base 110 and protrude downward. Specifically, the base 110 is the basic part of the mobile mechanism 100, providing a stable support and connection point so that other components can be installed on it. The driving unit 120 is a key component in the mobile mechanism 100, which is used to provide power and driving force. For example, an electric motor or a manual rotation device can be used. The driving unit 120 is usually located on the upper part of the base 110 and connected with other components to transmit power and movement. The driving wheel 130 is connected through its own rotating shaft so that the driving wheel 130 rotates actively. The driving wheel 130 is a wheel driven by the driving unit 120, which is used to provide the main driving force and movement. It is preferably arranged below the base 110 or partially protrudes below the base 110, and can directly contact the ground. Two or four driving wheels 130 are common. The auxiliary steering wheel 140 is an auxiliary wheel used to help control and adjust the direction of movement. It is usually located next to the driving wheel 130 or at the edge of the base 110, for example, it is set at the front end of the base 110, and the rear end is two driving wheels 130. The main function of the auxiliary steering wheel 140 is to change the direction and turning radius of the toy, and increase controllability and flexibility. The rotating shaft 141 of the auxiliary steering wheel 140 is set in two arc grooves, one arc groove is a small angle arc groove 1422, and the other arc groove is a large angle arc groove 1421, so that the rotating shaft can move in the same proportion in the two arc grooves to achieve the steering operation of the auxiliary steering wheel 140.

[0037] Among them, the main function of the auxiliary steering wheel 140 is: during the forward movement of the mobile mechanism 100, the auxiliary steering wheel 140 is always at the rear end position of the arc groove, that is, in the front direction, and the mobile mechanism 100 keeps moving forward; when encountering an obstacle, the mobile mechanism 100 starts to move backward through other functional components, such as touch sensing, infrared remote sensing and even remote control. During the backward movement, the auxiliary steering wheel 140 will move toward the front end of the arc groove due to friction with the ground until it reaches the front end position of the arc groove. At this time, the auxiliary steering wheel 140 is in the steering direction, and the mobile mechanism 100 will turn and move backward; when moving backward for a certain distance, the mobile mechanism 100 moves forward again. At this time, the auxiliary steering wheel 140 returns to the rear end position of the arc groove due to friction with the ground, and the mobile mechanism 100 continues to move forward, thereby realizing intelligent avoidance of obstacles.

[0038] The driving unit 120 performs torque conversion through the gear set 131, and then drives the driving wheel 130 to rotate through the rotating shaft 132. The gear set 131 is usually composed of a plurality of gears, each of which has a certain number of teeth. The gears transmit torque and motion through gear meshing. In the gear set, the size and number of teeth of the gears can be selected as needed to achieve the required torque and speed ratio. The gear set 131 can be composed of different types of gears, such as spur gears, helical gears, bevel gears, etc., and each type of gear has different characteristics and application ranges.

[0039] Furthermore, the gear ratio between the gears in the gear set 131 determines the conversion relationship between torque and speed. Larger gears are usually used to transmit larger torques, while smaller gears are used to provide higher speeds. The gears in the gear set 131 can be meshed in different ways, such as external meshing, internal meshing, etc. Gears are usually made of metal materials, such as steel, iron, etc., and the manufacturing process of gears needs to consider factors such as precision requirements and wear resistance.

[0040] When the toy moves, the concave-convex structure of the worm tail 310 can simulate the movement of the worm, which increases the fun and simulation of the toy. Since the worm tail 310 is detachable, the user can assemble and redesign it according to his or her own preferences and creativity. In particular, when the toy is provided to pets or children for fun, the worm tail 310 is easily damaged, and the worm tail 310 can be replaced quickly and timely to improve playability.

[0041] In this embodiment, reference Figures 1 to 3 The housing 300 further includes a head 320 , which is mounted on the mobile mechanism 100 , and can be fixedly installed or detachably installed. The outer contour of the head 320 is matched with the outer contour of the base 110 .

[0042] The head 320 is a part of the shell 300 and can be installed on the mobile mechanism 100, preferably installed on the base 110. The design of the head 320 can be diversified according to the user's preferences and creativity. For example, the head 320 can be in the shape of a worm's head 320, or in the shape of other animals or objects, or even an abstract geometric shape. By removing and replacing different heads 320, players can change the appearance and theme of the toy. At the same time, the most important function of the head 320 is to protect the relevant components on the mobile mechanism 100.

[0043] In this embodiment, the head 320 is made of a material with preset hardness or elasticity, and the material with preset hardness or elasticity is one of PVC blister material, ABS plastic material, PC plastic material, PE plastic material, PP plastic material and PC mixed ABS plastic material; the worm tail 310 is made of a material with preset softness, and the material with preset softness is one of paper material, plush material, TPU material, rubber material, silk material and leather material.

[0047] Among them, a snap-fit ​​connection structure is arranged between the worm tail 310 and the support frame 200, and the connection can be achieved by docking the raised part on the worm tail 310 with the groove part on the support frame 200. This connection method is simple and convenient, and the worm tail 310 can be quickly installed and disassembled, so that players can easily replace different worm tails 310.

[0048] A threaded connection structure is provided between the worm tail 310 and the support frame 200. The worm tail 310 has a threaded portion, and the support frame 200 has a corresponding threaded hole. By rotating and tightening the worm tail 310, the threaded portion and the threaded hole are interlocked with each other to achieve a stable connection, providing a more secure connection, which is suitable for situations where a stronger fixation is required.

[0049] A slot connection structure is provided between the worm tail 310 and the support frame 200. There is a protruding slot on the worm tail 310, and there is a corresponding raised portion on the support frame 200. The slot on the worm tail 310 is docked with the raised portion on the support frame 200 so that they are embedded in each other to achieve connection. The connection method is simple and easy, and at the same time provides a certain degree of stability.

[0050] A magnetic connection structure is provided between the worm tail 310 and the support frame 200. The worm tail 310 and the support frame 200 are respectively provided with magnets that attract each other. Through the action of magnetic force, the worm tail 310 can be easily adsorbed on the support frame 200 to achieve connection, which is convenient for quick installation and disassembly, and at the same time provides a certain stability.

[0051] The worm tail 310 and the support frame 200 can be connected by glue. Appropriate glue is applied to the contact portion of the worm tail 310 and the support frame 200, and then they are tightly bonded together to provide a firm connection, but generally not easy to disassemble.

[0052] In this embodiment, reference Figures 3 to 6, the support frame 200 is arranged at the rear end edge of the base 110, the support frame includes a connecting frame and a linkage structure, the linkage structure is arranged in linkage with the driving wheel 130, and moves forward and backward during the rotation of the driving wheel 130, the connecting frame is fixedly arranged on the linkage structure, and moves forward and backward driven by the forward and backward movement of the linkage structure; wherein, one end of the worm tail 310 is detachably connected to the connecting frame. Specifically, the linkage structure includes a moving part 151 and a connecting part 153, the two moving parts 151 are respectively arranged to fit the surface of the driving wheel 130, and the moving part 151 includes a vertically arranged waist-shaped groove 1511, the surface of the driving wheel 130 is provided with a protrusion 131 at the center of the rotation circle and inserted into the waist-shaped groove 1511, the moving part 151 is also arranged to slide forward and backward with the base 110, the two moving parts 151 are connected by the connecting part 153, and the connecting frame is fixedly connected to the connecting part 153.
