[0025] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0026] Please refer to Figure 1-Figure 7 As shown, the toy crab disclosed in this embodiment includes an outer shell, which is composed of a lower shell 1 with an open top and an upper shell 2 arranged on the top of the lower shell 1 for sealing the top of the lower shell 1, which are detachably connected and spliced ​​with each other. Crab claws 16 are arranged on both sides of the top of the upper shell 2, and the bottom ends of the crab claws 16 are fixedly connected to the surface of the upper shell 2. The inner cavity of the crab claws 16 is provided with an obstacle avoidance sensor 17. The obstacle avoidance sensor 17 is a mature existing technology. Its main function is to detect the existence of an obstacle in front within a specified distance, and to control the driving mechanism to rotate in the opposite direction, so that the toy crab can achieve the obstacle avoidance function, and the surface of the crab claws 16 is provided with a through hole to ensure the normal use of the obstacle avoidance sensor 17.

[0027] The bottom of the lower shell 1 is rotatably connected with a rotating shaft 9 along the front end to the rear end direction of the lower shell 1. The two ends of the rotating shaft 9 respectively penetrate the front end and the rear end of the inner cavity of the lower shell 1. The two ends of the rotating shaft 9 are respectively rotatably connected with the two ends of the inner wall surface of the lower shell 1, thereby ensuring the normal rotation of the rotating shaft 9. The rear end of the inner cavity of the lower shell 1 is provided with a driving mechanism for driving the rotating shaft 9 to rotate, and the driving mechanism enables the rotating shaft 9 to selectively rotate in forward rotation or reverse rotation.

[0028] A first running wheel 7 is provided at the front end of the surface of the rotating shaft 9, and a second running wheel 8 is provided at the rear end of the surface of the rotating shaft 9. The first running wheel 7 and the second running wheel 8 are both fixedly connected to the surface of the rotating shaft 9, and the outer ring surfaces of the first running wheel 7 and the second running wheel 8 are both provided with friction patterns. A simulation component is provided at the bottom of the lower shell 1 and between the first running wheel 7 and the second running wheel 8. The simulation component is used to simulate the movement of the crab through the simulation component when the rotating shaft 9 rotates to drive the first running wheel 7 and the second running wheel 8 to rotate to make the toy crab move, thereby increasing the fun.

[0029] The simulation component includes a first crab leg 3, a second crab leg 4 and a third crab leg 5 which are staggered in sequence. The first crab leg 3, the second crab leg 4 and the third crab leg 5 are all composed of crab leg structures whose ends are movably connected to each other. The first crab leg 3 is detachably arranged at an eccentric position of the inner surface of the second walking wheel 8, and the third crab leg 5 is detachably arranged at an eccentric position of the inner surface of the first walking wheel 7. The eccentricities of the first crab leg 3 and the third crab leg 5 are at the same height position but are staggered with each other, thereby ensuring that the first crab leg 3 and the third crab leg 5 are at the same horizontal position. The second crab leg 4 is connected to the first crab leg 3 and the third crab leg 5 through a connecting component.

[0030] Furthermore, the connecting component includes a first connecting member 10 and a second connecting member 11. The first connecting member 10 is arranged on the inner surface of the first crab leg 3 and connected to the surface of the second crab leg 4. The second connecting member 11 is arranged on the inner surface of the third crab leg 5 and connected to the surface of the second crab leg 4. The ends of the first connecting member 10 and the second connecting member 11 respectively connected to the inner surfaces of the first crab leg 3 and the third crab leg 5 are staggered with each other, and the first connecting member 10 and the second connecting member 11 are staggered with the rotating shaft 9 and are not at the same horizontal height.

[0031] Furthermore, the driving mechanism includes a servo motor 12 and a cylindrical gear 14 arranged at the rear end of the inner cavity of the lower shell 1. The inner end of the cylindrical gear 14 is rotatably connected to the inner wall surface of the lower shell 1. The bottom end of the servo motor 12 is provided with a worm 13 for driving the cylindrical gear 14 to rotate. The cylindrical gear 14 is composed of a spherical column and a gear, and its gear part is meshed with the worm 13. The surface of the worm 13 and the surface of the rotating shaft 9 are provided with a connecting gear 15 meshing with the cylindrical gear 14. The spherical column part of the cylindrical gear 14 is meshed with the connecting gear 15. The driving mechanism is electrically connected to the obstacle avoidance sensor 17. When the obstacle avoidance sensor 17 detects an obstacle, the driving mechanism sends a signal to make the worm 13 rotate in the opposite direction, thereby causing the crab toy body to move in a direction away from the obstacle.

[0032] Furthermore, decorative crab legs 6 are provided on both sides of the rear end of the lower shell 1. The two decorative crab legs 6 are fixedly connected to the surface of the lower shell 1, and the volume of the decorative crab legs 6 is smaller than the first crab leg 3, the second crab leg 4 and the third crab leg 5, ensuring that they will not come into contact with the ground during use, and mainly play the role of decoration, beautification and simulation.

[0033] Furthermore, the inner cavities of the first running wheel 7 and the second running wheel 8 are both provided with triangular support rods 20, and the triangular support rods 20 strengthen the support of the first running wheel 7, so that the toy crab body is more stable during movement.

[0034] Furthermore, two crab eyes 18 are spaced apart on the surface of the upper shell 2. There is a certain distance between the two crab eyes 18 to make the toy more realistic and to serve as a decoration.

[0035] Furthermore, the inner cavity of the lower shell 1 is provided with a power supply module 19, which provides power support for the driving mechanism and the obstacle avoidance sensor 17, and the crab eye 18 is a mature existing mechanism, so no further explanation is given.

[0036] Normally, when the toy crab is in use, the driving mechanism is used to rotate the rotating shaft 9 in the forward direction, driving the first walking wheel 7 and the second walking wheel 8 to move, so that the toy crab body moves on the ground, and the first crab leg 3 and the third crab leg 5 are respectively moved synchronously by the rotation of the first walking wheel 7 and the second walking wheel 8, and the second crab leg 4 is driven to move when the first crab leg 3 and the third crab leg 5 move through the connecting component, and the first crab leg 3, the second crab leg 4 and the third crab leg 5 simulate the movement of the crab, and the two obstacle avoidance sensors 17 sense obstacles on both sides. When the obstacle avoidance sensor 17 on one side senses an obstacle, the driving mechanism causes the rotating shaft 9 to rotate in the opposite direction, so that the toy crab body moves in the opposite direction to avoid the obstacle.

[0037] When the rotating shaft 9 needs to be rotated, the servo motor 12 can drive the worm 13 to rotate forward or reversely. Since the cylindrical gear 14 is meshed with the connecting gear 15, the rotating shaft 9 is driven to rotate forward or reversely. When the rotating shaft 9 is driven forward to rotate to make the toy crab body move, when the obstacle avoidance sensor 17 detects that there is an obstacle in the forward direction, the servo motor 12 drives the worm 13 to drive the rotating shaft 9 to rotate reversely.

[0038] The above are only preferred implementations of the present invention and are not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
