Description

Technical Field

[0001] This utility model relates to the field of toy products, specifically to an arm assembly for toy dolls. Background Art

[0002] Toy dolls are very popular with children. Toy dolls on the market typically consist of a body shell, upper limb shells, and lower limb shells, with the upper and lower limb shells attached to the body shell. To enrich the design of toy dolls, some toys also include accessories that can be detachably attached to the main body. For example, some robot-shaped dolls also include shoulder armor shells. To facilitate the installation of the shoulder armor shells, ball heads are usually provided on the body or upper limb shells, while ball grooves are provided on the shoulder armor shells. The ball heads can be movably connected to the ball grooves, allowing the shoulder armor shells to be installed. However, the shell that forms the spherical groove is a complete, unbroken structure with limited deformability. The opening diameter of the spherical groove is usually smaller than the outer diameter of the spherical head. When assembling the shoulder armor shell onto the doll, a large force needs to be applied to the shoulder armor shell to make the spherical head open the opening of the spherical groove, causing the opening of the spherical groove to deform. The shoulder armor shell will return to its original shape after the spherical head is fully accommodated in the spherical groove. This assembly method is laborious because the shell that forms the spherical groove is a complete, unbroken structure with very little deformation, which is not conducive to improving work efficiency. Moreover, after repeated disassembly and assembly of the shoulder armor shell, it is easy to cause the shoulder armor shell to crack, break, and be damaged, resulting in poor durability of the toy.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0050] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] See Figures 1 to 9As shown, this application embodiment provides an arm assembly for a toy doll, including: a transition joint 2, an upper limb shaping shell 3, and a shoulder armor shaping shell 4. The transition joint 2 is movably connected to the body shaping shell 1 of the toy doll, and a first movable connector 21 is provided on the transition joint 2. The upper limb shaping shell 3 is rotatably connected to the transition joint 2. A connecting tube 41 is provided on the shoulder armor shaping shell 4, the connecting tube 41 having a first connecting groove and a notch 411 provided on the connecting tube 41, the notch 411 communicating with the first connecting groove, the connecting tube 41 being movably fitted onto the first movable connector 21, and the shoulder armor shaping shell 4 partially covering the upper limb shaping shell 3.

[0053] The shoulder armor shaped shell 4 of the arm assembly of the toy doll provided in this application embodiment has a notch 411 on the connecting tube 41, which facilitates demolding, increases the deformability of the connecting tube 41, and facilitates the smooth assembly of the first movable connector 21 into the first connecting groove of the connecting tube 41. The assembly of the shoulder armor shaped shell 4 can be completed without the assembly personnel applying a large squeezing force, which significantly improves the assembly efficiency.

[0054] In some possible implementations, the connecting pipe 41 has an opening communicating with the first connecting groove, and at least two notches 411 are provided on one side of the opening. Each notch 411 is arranged sequentially at intervals along the circumference of the connecting pipe 41, and each notch 411 divides the connecting pipe 41 into a plurality of elastic sheets.

[0055] When assembling the shoulder armor shell 4, the first movable connector 21 can push apart each elastic piece, so that the elastic pieces are separated, which facilitates the smooth insertion of the first movable connector 21 into the first connecting groove. When the first movable connector 21 is inserted into the first connecting groove, each elastic piece returns to its original shape, and the first movable connector 21 will not easily detach from the first connecting groove.

[0056] In some possible implementations, a second connecting groove 11 is provided on the body shell 1, and a second movable connector 22 is provided on the transition joint 2. The outer surface of the second movable connector 22 is provided with a first groove 221, and the second movable connector 22 is movably connected to the second connecting groove 11.

[0057] The second movable connector 22 is provided with first grooves 221 on its opposite sides. By providing first grooves 221 on the second movable connector 22, the rotational resistance of the second movable connector 22 relative to the body shell 1 can be increased.

[0058] For example, the body shell 1 is at least partially made of soft rubber, and the soft rubber structure has the second connecting groove 11. When the second movable connector 22 is accommodated in the second connecting groove 11, the soft rubber structure partially deforms and extends into the first groove 221, thereby increasing the rotational resistance of the second movable connector 22.

[0059] In some possible implementations, the upper limb shaping shell 3 includes an upper arm portion 31, a lower arm portion 32, and a hand portion 33, wherein the transition joint 2, upper arm portion 31, lower arm portion 32, and hand portion 33 are arranged sequentially, and adjacent transition joints 2, upper arm portion 31, lower arm portion 32, and hand portion 33 are movably connected.

[0060] In some possible implementations, the transition joint 2 is provided with a second groove 23 on both sides, the upper arm portion 31 has two first extensions 311, the two first extensions 311 are spaced apart, and each of the two first extensions 311 is provided with a first boss 3111. The transition joint 2 is accommodated between the two first extensions 311, and the first bosses 3111 on the two first extensions 311 are rotatably connected to the corresponding second groove 23.

[0061] In some possible implementations, the upper limb shaping shell 3 includes a first hinge 34 and a second hinge 35. A third connecting groove 312 is provided on the upper arm portion 31, and a fourth connecting groove 321 is provided on the lower arm portion 32. The first hinge 34 and the second hinge 35 are movably connected. A third movable connector 341 is provided on the first hinge 34, and the third movable connector 341 is movably connected to the third connecting groove 312. A limiting connector 351 is provided on the second hinge 35, and the limiting connector 351 is connected to the fourth connecting groove 321. The provision of the first hinge 34 and the second hinge 35 increases the degree of freedom of movement for the upper arm portion 31 and the lower arm portion 32.

[0062] In some possible implementations, the first hinge 34 includes two second extensions 342, which are spaced apart. Each of the two second extensions 342 is provided with a second boss 3421. The second hinge 35 is provided with third grooves 352 on both sides. The second hinge 35 is accommodated between the two second extensions 342. The second bosses 3421 on the two second extensions 342 are rotatably connected to the corresponding third grooves 352.

[0063] The second hinge 35 has a locking protrusion 3511 and a through deformation groove a on its limiting connector 351. The limiting connector 351 has two limiting mating surfaces 3512. The fourth connecting groove 321 has an inner protrusion 3211 and two spaced-apart limiting surfaces 3212. When the limiting connector 351 is connected to the fourth connecting groove 321, the locking protrusion 3511 of the limiting connector 351 engages with the inner protrusion 3211, and the two limiting mating surfaces 3512 of the limiting connector 351 respectively abut against the two limiting surfaces 3212. The limiting surfaces 3212 can engage with the limiting mating surfaces 3512 to prevent relative rotation between the second hinge 35 and the lower arm 32. A forearm armor shell b can be fitted onto the lower arm 32.

[0064] In one possible implementation, a fifth connecting groove 322 is provided on the lower arm portion 32, and a fourth movable connecting head 331 is provided on the hand portion 33. The fourth movable connecting head 331 is provided with a deformation groove a, and the fourth movable connecting head 331 is movably connected to the fifth connecting groove 322.

[0065] By setting the deformation groove a, the fourth movable connector 331 has a certain deformation capability and can be smoothly assembled into the fifth connecting groove 322. For example, if the opening diameter of the fifth connecting groove 322 is small, the fourth movable connector 331 will abut against the opening and undergo a certain deformation, so that it can smoothly enter the interior of the fifth connecting groove 322. The fourth movable connector 331 will recover its deformation and will not easily detach from the fifth connecting groove 322.

[0066] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
