[0029] To make the technical problems solved by the present application, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0030] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected", "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0032] As Figures 1 - 8 shown, this embodiment provides an electric crab toy, including: a housing 1, a driving mechanism 2 and an eye mechanism 3; the driving mechanism 2 is disposed at the bottom of the housing 1 and is configured to drive the housing 1 to move horizontally; the eye mechanism 3 is movably disposed on the housing 1, and the eye mechanism 3 includes a power member 301, a movable member 302, a transmission member 303 and two eye members 304. The power member 301 is installed inside the housing 1, the movable member 302 is installed at the power output end of the power member 301, and an eccentric connecting column 3021 is protruded from one end of the movable member 302 away from the power member 301. A rectangular slot 3031 is defined in the transmission member 303 and is in mating connection with the connecting column 3021. Transmission columns 305 are disposed at both ends of the transmission member 303 and are movably connected to the eye members 304. At least a part of the two eye members 304 extends out of the housing 1.

[0033] The eye mechanism 3 is configured such that the power member 301 drives the movable member 302 to perform a circular motion, the movable member 302 drives the transmission member 303 to perform a pendulum motion through the connecting column 3021, and further drives the two eye members 304 to swing horizontally through the two transmission columns 305.

[0034] Based on the above scheme, the driving mechanism 2 arranged at the bottom of the shell 1 is responsible for providing the power for the lateral movement of the entire toy. This mechanism may adopt mechanical structures such as motors and gear sets. By controlling the rotation direction and speed of the motor, the crab toy can be moved horizontally to the left and right, simulating the walking method of a real crab. The eye mechanism 3 is one of the innovative points of this application. It includes a power part 301, a movable part 302, a transmission part 303 and two eye parts 304. The power part 301 is installed inside the shell 1, usually a small motor, which is responsible for providing power for the eye swing. The movable part 302 is installed at the power output end of the power part 301 (such as the rotating shaft of the motor). One end of the movable part 302 is eccentrically convexly provided with a connecting column 3021. When the power part 301 rotates, the movable part 302 performs a circular motion accordingly; the transmission part 303 is provided with a connection column 3021 connected to the movable part 302. The connecting column 3021 of the movable part 302 cooperates with the rectangular groove 3031. This design enables the circular motion of the movable part 302 to be converted into the pendulum motion of the transmission part 303. That is, as the movable part 302 rotates, the connecting column 3021 slides in the rectangular groove 3031, driving the transmission part 303 to swing left and right; the two eye parts 304 are movably connected to the transmission part 303 through the transmission column 305. Therefore, when the transmission part 303 performs a pendulum motion, it will drive the two eye parts 304 to swing horizontally synchronously, simulating the activity effect of the crab's eyes. By adding the eye mechanism 3, the crab toy can realize the swing of the eye part on the basis of lateral movement. This novel design greatly increases the fun and interactivity of the toy, and can attract children's attention and interest. The electric crab toy described in this scheme can not only allow children to experience fun in playing, but also understand the basic biological characteristics of crabs by observing the movement of the crab toy and the swing of the eyes, and enhance children's cognition of the natural world. At the same time, the design of the eye mechanism 3 adopts an ingenious mechanical transmission principle, which converts the circular motion of the motor into the lateral swing of the eye component 304, and optimizes the gameplay and function of the toy with a simple mechanical transmission structure, making the electric crab toy more playable and more playable.

[0035] In some embodiments, the transmission column 305 includes a column portion 3051 and a limiting portion 3052. An elliptical groove 3041 is formed on the eye component 304. The column portion 3051 is inserted into the elliptical groove 3041, and the limiting portion 3052 abuts against the outer peripheral surface of the elliptical groove 3041 to form a limiting lock. The column portion 3051 is the main part of the transmission column 305, and its diameter matches the width of the elliptical groove 3041 formed on the eye component 304, enabling the column portion 3051 to smoothly pass through the elliptical groove 3041. The design of the elliptical groove 3041 allows the column portion 3051 to move along a certain trajectory within the groove, thereby driving the eye component 304 to swing laterally. The limiting portion 3052 is located outside the column portion 3051, and its diameter is larger than the width of the elliptical groove 3041. Therefore, when the transmission column 305 is inserted into the elliptical groove 3041, the limiting portion 3052 will abut against the outer peripheral surface of the elliptical groove 3041, forming the effect of limiting lock. This design prevents the transmission column 305 from moving excessively or falling off inside the eye component 304, ensuring the stability and safety of the eye component 304 during the swinging process. Through this cooperative design of the transmission column 305 and the elliptical groove 3041, the eye mechanism 3 of the electric crab toy can achieve a more precise and stable eye swinging effect. At the same time, the presence of the limiting portion 3052 also effectively avoids the risk of component detachment caused by children's misoperation during play, improving the overall safety and durability of the toy.

[0036] Further, a movable hole 101 is formed at the top of the outer shell 1. The eye component 304 is inserted into the movable hole 101 and can swing laterally within the movable hole 101. The position, shape, and size of the movable hole 101 are designed to match each other to ensure that the eye component 304 can be smoothly and stably inserted therein and swing laterally when needed. This design not only ensures the flexibility and freedom of the eye component 304 but also makes the entire eye mechanism 3 more visually compact and beautiful. When the power member 301 drives the movable member 302 to perform a circular motion, the transmission column 305 is driven through the pendulum-like motion of the transmission member 303, and then the eye component 304 is driven to swing laterally within the movable hole 101. Due to the limiting effect of the movable hole 101, the swinging range of the eye component 304 is effectively controlled within a certain area, avoiding potential damage or safety hazards caused by excessive swinging.

[0037] In addition, the design of the movable hole 101 also takes into account sealing and dust prevention. On the premise of not affecting the swinging of the eye component 304, sealing materials or dust-proof nets and other structures can be provided at the edge of the movable hole 101 to prevent impurities such as dust and dirt from entering the interior of the outer shell 1 and affecting the mechanical performance and service life of the toy.

[0038] Furthermore, an abutting portion 3042 is provided on the eye component 304. The transverse two ends of the abutting portion 3042 are arc surfaces 3043. When the eye component 304 swings transversely, the arc surfaces 3043 are abutted against and limited by the hole wall of the movable hole 101. The abutting portion 3042 is located at a specific position of the eye component 304, and its transverse two ends are designed as arc surfaces 3043. The design of such arc surfaces 3043 is not only beautiful, but more importantly, when the eye component 304 swings transversely, it can form smooth contact and abutment with the hole wall of the movable hole 101 at the top of the housing 1. When the eye component 304 swings to the limit position, the arc surface 3043 will naturally fit with the hole wall, thereby playing a role in limiting, preventing the eye component 304 from being damaged or disengaged from the movable hole 101 due to excessive swinging.

[0039] Meanwhile, the design of the arc surface 3043 also helps to reduce the friction and wear between the eye component 304 and the hole wall of the movable hole 101. During the swinging process, the arc surface 3043 can guide the eye component 304 to move along a predetermined trajectory, ensuring the smoothness and fluency of the swinging. This guiding effect not only extends the service life of the toy, but also improves the overall performance and user experience of the toy.

[0040] Generally speaking, it also includes two clamping portions 4, and the two clamping portions 4 are symmetrically installed on both sides of the eye mechanism 3. In the complete design of the electric crab toy, in addition to the core components such as the housing 1, the driving mechanism 2, and the eye mechanism 3 mentioned above, usually two clamping portions 4 are also included as auxiliary elements to enhance the simulation and interest of the toy. The two clamping portions 4 are symmetrically installed on both sides of the eye mechanism 3, simulating the pincers of a real crab. The design of the clamping portion 4 can be diversified, but usually attention is paid to the realism of its appearance and the flexibility of its operation. For example, the clamping portion 4 can be designed as a structure that can be slightly opened and closed, and this effect is achieved through an internal spring or other mechanical devices. When a child operates the toy, the opening and closing actions of the clamping portion 4 will add more interactivity and interest. Moreover, the installation positions of the clamping portions 4 are also carefully considered. Arranging them symmetrically on both sides of the eye mechanism 3 not only maintains the overall balance and beauty of the toy, but also makes the actions of the clamping portions 4 and the eye component 304 echo each other, more vividly simulating the natural behavior of the crab.

[0041] Based on the solution with the clamping portion 4 provided, at least one of the clamping portions 4 can clamp a columnar object. Specifically, the clamping portion 4 is provided with a through mounting hole 401, and the columnar object is inserted into the mounting hole 401. In order to further improve the playability and interest of the toy, at least one of the clamping portions 4 can be designed to have the function of clamping a columnar object. This design allows children to freely match different columnar objects during the play process, creating more diverse game scenarios and role settings.

[0042] In terms of specific implementation, a through mounting hole 401 can be formed on the clamping part 4. The shape and size of this mounting hole 401 need to be precisely matched according to the designed columnar object to ensure that the columnar object can be stably inserted therein. After the columnar object is inserted into the mounting hole 401, the clamping part 4 can clamp the columnar object like the pincers of a real crab, making it not easy to fall off when the toy moves or interacts. The design of the columnar object can be diversified, including but not limited to swords, guns, shields, etc. These columnar objects can be provided individually or as part of a toy set to consumers. By replacing different columnar objects, children can create different game characters and battle scenes according to their preferences and imaginations.

[0043] In addition, to ensure the stable and safe connection between the columnar object and the clamping part 4, some anti-slip or fixing structures, such as rubber gaskets, buckles, etc., can be provided inside the mounting hole 401. These structures can increase the friction or locking force between the columnar object and the clamping part 4, preventing the columnar object from falling off or being damaged due to accidental collisions or pulls during play.

[0044] Among them, the columnar object can be in the shape of a specific weapon, such as an axe, a knife, a sword or a halberd, etc.

[0045] Optionally, the power member 301 is an electric motor. The electric motor has the advantages of small volume, light weight, high rotational speed, large output torque, etc., and is very suitable for driving the motion mechanism of small toys. In the electric crab toy, the electric motor can be installed in the internal space of the toy. When the electric motor is started, it converts electrical energy into mechanical energy through the internal electromagnetic induction principle and drives the rotor to rotate. This rotational motion is then transmitted to each motion mechanism, enabling the toy to move according to the preset actions. For example, in the eye mechanism 3, the electric motor can drive the movable member 302 to perform a circular motion, thereby driving the transmission member 303 and the eye member 304 to achieve lateral swing; in the clamping part 4, by setting a transmission structure to connect the power member 301 and the clamping part 4, the electric motor can also provide power support for the opening and closing of the clamping part 4.

[0046] In addition, the electric motor also has the advantages of convenient control, low noise and simple maintenance. By adjusting the input voltage or current magnitude of the electric motor, the movement speed and force of the toy can be easily controlled; at the same time, the operating noise of the electric motor is relatively small and will not cause adverse effects on children's hearing; finally, the structure of the electric motor is relatively simple, and once a failure or damage occurs, it is also relatively easy to repair or replace.

[0047] As an alternative specific implementation, a spring is provided inside the clamping part 4. The spring provides an elastic driving force for the movement of the clamping part 4. For example, when an external force is applied to the clamping part 4 to open it, the spring is compressed at this time. When the force acting on the clamping part 4 is removed, the elastic force of the spring causes the clamping part 4 to close; or when an external force is applied to the clamping part 4 to close it, the spring is compressed at this time. When the force acting on the clamping part 4 is removed, the elastic force of the spring causes the clamping part 4 to open.

[0048] In some embodiments, the driving mechanism 2 includes a driving gearbox, a first driving wheel, a second driving wheel and a crab leg assembly. The first driving wheel and the second driving wheel are arranged front and back at the bottom of the housing 1. The crab leg assembly is arranged between the first driving wheel and the second driving wheel. The driving gearbox is connected to the first driving wheel or the second driving wheel for the synchronous movement of the first driving wheel, the second driving wheel and the crab leg assembly. In this solution, first, the first driving wheel and the second driving wheel are cleverly arranged at the bottom of the toy housing 1, and they are arranged front and back between them. This layout ensures that the toy can maintain stable support and balance when moving, and at the same time provides enough space for the installation and movement of the crab leg assembly. The crab leg assembly is cleverly arranged between the first driving wheel and the second driving wheel, simulating the structure and function of the real crab legs. These crab leg assemblies not only increase the simulation degree of the toy, but also enhance the flexibility and dynamic sense of the toy through their movement. The driving gearbox, as the core component of the entire driving mechanism 2, is closely connected to the first driving wheel or the second driving wheel (usually directly connected to one of them, and the other is indirectly connected through a transmission device). The driving gearbox contains precise gear sets and transmission mechanisms inside, which can convert the power generated by a power source such as an electric motor into the rotational or swinging motion required by the driving wheels and the crab leg assembly. Through the precise control of the driving gearbox, the first driving wheel, the second driving wheel and the crab leg assembly can achieve synchronous movement, which means that when the toy starts, all the wheels will rotate at the same speed, and at the same time the crab leg assembly will swing along a preset trajectory, thereby pushing the toy forward or performing other complex actions. This design not only improves the motion performance and stability of the electric crab toy, but also makes the toy more realistic and interesting when walking and moving. Moreover, children can experience the unique charm of crab walking by controlling the moving direction and speed of the toy when playing, and at the same time can exercise their hand-eye coordination ability and imagination.

[0049] In order to further improve the stability of the electric crab toy during lateral movement, an auxiliary wheel set is also provided at the bottom of the shell 1. In order to ensure that the toy can remain stable during lateral movement and prevent rollover or loss of control due to center of gravity shift or uneven ground, an auxiliary wheel set can be additionally provided at the bottom of the shell 1. The auxiliary wheel set is usually composed of a plurality of small wheels, which are evenly distributed at the edge of the bottom of the toy and complement the driving mechanism 2. These small wheels can not only provide additional support when the toy moves, but also reduce the friction between the toy and the ground by rolling, making the movement smoother and more stable.
