These dolls with special functions can increase interactivity and fun, making Doraemon dolls a popular gift choice.

[0003] Most ordinary Doraemon dolls on the market do not require a skeleton. However, for some dolls that require specific poses or more three-dimensional shapes, simple internal support structures such as plastic rods and metal wires are used. The support strength of these structures is not ideal, and children are prone to dropping or squeezing the dolls during play, which can lead to the breakage or deformation of the internal support components of the Doraemon dolls. Furthermore, it is not convenient to disassemble and replace the structure, so there is room for improvement. Utility Model Content

The driving component 5 includes a connecting shaft 51 provided on the inner wall of the body 1. The robot cat skeleton is composed of the body 1, base 2, skull 3 and arm frames 4. The skeleton is made of high-strength aluminum alloy, which has the advantages of low density and high strength, thus reducing the structural weight.

[0023] The connecting assembly 6 is disposed on one side of the boom 4. The connecting assembly 6 includes a connecting seat 61 fixed to one end of the boom 4. Two positioning holes 62 are symmetrically arranged on the inner wall of the connecting seat 61. The connecting assembly 6 also includes a connecting plate 63 disposed on the inner wall of the connecting shaft 51. A positioning pin 64 is fixedly connected to the top of the connecting plate 63, and a first spring 65 is fixedly connected to the bottom of the connecting plate 63. The connecting assembly 6 also includes a guide rod 66 that slides on the inner wall of the connecting plate 63. One end of the guide rod 66 is fixedly connected to the inner wall of the connecting shaft 51. When assembling the boom 4… The movable arm 4 connects the connecting seat 61 to the connecting shaft 51. The inner wall of the connecting seat 61 presses against the positioning pin 64. The top of the positioning pin 64 is arc-shaped. The positioning pin 64 is pressed back into the connecting shaft 51, and the connecting plate 63 moves along the guide rod 66 and presses the first spring 65. When the connecting shaft 51 is inserted into the connecting seat 61, the positioning pin 64 is automatically reset and popped out from the positioning hole 62 by the first spring 65, thus completing the fixation of the arm 4. When disassembling, press the positioning pin 64 and then move the arm 4 away from the connecting shaft 51. The operation is convenient.

[0024] The driving component 5 also includes a gear 52 fixed to the outside of the connecting shaft 51. A guide rail 53 is fixedly connected to the inner wall of the body 1, and a rack 54 is slidably connected to the inner wall of the guide rail 53. The gear 52 and the rack 54 are meshed together. The driving component 5 also includes a miniature electric push rod 55 fixed to the inner wall of the body 1 by screws. The top rod of the miniature electric push rod 55 is fixedly connected to the bottom of the rack 54. When the miniature electric push rod 55 is activated, the rack 54 moves up and down along the guide rail 53 and drives the gear 52 to rotate in sync. This allows the connecting shaft 51 to drive the arm frame 4 to swing through the connecting component 6, making the Doraemon doll perform the "Gong Xi Fa Cai" (Wishing you prosperity) action, which increases the fun.

[0025] A battery compartment 7 is provided at the bottom of the body 1, extending downwards to the bottom of the base 2. A cover plate 8 is rotatably connected to the inner wall of the battery compartment 7. A wire hole is provided on the inner wall of the body 1, which is connected to the battery compartment 7. The battery compartment 7 is used to house a battery, which powers the miniature electric actuator 55. The cover plate 8 is used to protect the battery. The cable of the miniature electric actuator 55 is electrically connected to the battery in the battery compartment 7 through the wire hole.

[0026] The inner wall of the battery compartment 7 is provided with an arc-shaped groove 9. The inner wall of the cover plate 8 is fixedly connected with a second spring 10, and the inner wall of the cover plate 8 is slidably connected with an arc-shaped block 11. One end of the second spring 10 is fixedly connected to one side of the arc-shaped block 11. After the battery is installed in the battery compartment 7, the cover plate 8 is rotated to make the inner wall of the battery compartment 7 press the arc-shaped block 11 and retract it into the cover plate 8. At this time, the second spring 10 is in a compressed state. When the cover plate 8 is horizontal, the arc-shaped block 11 and the arc-shaped groove 9 are also in a horizontal state. The second spring 10 can make the arc-shaped block 11 automatically reset and lock into the arc-shaped groove 9. The initial force of the second spring 10 can make the arc-shaped block 11 and the arc-shaped groove 9 stable, thereby fixing the cover plate 8 on the battery compartment 7.

[0027] Working principle: The robot cat skeleton consists of a body 1, a base 2, a skull 3, and an arm frame 4, and is made of high-strength aluminum alloy, which has the advantages of low density and high strength, improving the support strength of the skeleton and reducing the structural weight. By moving the arm frame 4, the connecting seat 61 is connected to the connecting shaft 51. The inner wall of the connecting seat 61 presses the positioning pin 64 to retract it into the connecting shaft 51, and the connecting plate 63 presses the first spring 65. When the connecting shaft 51 is inserted into the connecting seat 61, the positioning pin 64 automatically pops out from the positioning hole 62 through the first spring 65, thus completing the fixation of the arm frame 4. To disassemble, press the positioning pin 64 and then move the arm frame 4 away from the connecting shaft 51. The operation is convenient.
