Abstract
Description
Technical Field
[0001] This utility model relates to toy doll manufacturing technology, and in particular to a BJD doll head that achieves movable eyelids and modular replacement of eye pieces through a pivot structure. Background Technology
[0002] Existing BJD dolls have the following defects in their eye structure: holes in the face shell for the eyes, no eyelids, and inability to simulate natural blinking. This invention aims to solve the above problems through modular design and a movable structure. Summary of the Invention
[0003] To address the technical limitation of BJD dolls' heads lacking movable eyelids, this invention provides a BJD head shell structure that supports independent opening and closing of the left and right eyelids, allows for quick replacement of eyepieces, and avoids interference between components.
[0004] The technical solution adopted in this utility model is as follows: a pair of pivot seats (13, 14) are provided on the inner side of the face shell (1), wherein the central pivot seat (13) fixes the inner pivot (112) of the eyelid (11), and the left and right pivot seats (14) fix the outer pivot (111) of the eyelid (11). The eyelash (113) is located below the eyelid (11) and is stuck in the eye frame of the face shell (1), restricting the eyelid (11) from turning over, so that the turning angle is just between the closed and open eye states, realizing the independent control of the left and right eyelids (11) to open and close around the axis; the eye piece (41) is fixed to the eye piece plate (42), and the eye piece plate (42) can be detachably installed on the insertion position (433) on the eye piece baffle (43); the eye piece baffle (43) is inserted into the anti-rotation positioning groove (12) and connected to the face shell (1) through the positioning post (431).
[0005] The eyepiece baffle (43) has a pull handle (432) on the back of the positioning post (431) for manually removing the eyepiece assembly.
[0006] The eyelid (11) covers the eyepiece (41) in a closed state, but the eyepiece (41) remains in a fixed position while suspended in the air, and there is no movement interference between the two. Beneficial effects
[0007] This invention achieves natural opening and closing of the eyelids and quick replacement of modular eyepieces through a pivot structure, solving the problem of simple and monotonous eye structure in existing BJD dolls. It enhances functionality while taking into account aesthetic expansion potential, and has high market application value. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0017] Assembly: As shown in Figures 3, 4, and 5, a pair of pivot seats (13 and 14) are provided on the inner side of the face shell (1). The central pivot seat (13) fixes the inner pivot (112) of the eyelid (11), and the left and right pivot seats (14) fix the outer pivot (111) of the eyelid (11). The eyelashes (113) are located below the eyelid (11) and are stuck in the eye frame of the face shell (1), restricting the eyelid (11) from turning over, so that the turning angle is exactly between the closed and open eye states, so that the left and right eyelids (11) can be independently controlled to open and close around the axis. As shown in Figure 6, the eyepiece (41) is fixed to the eyepiece plate (42), and the eyepiece plate (42) is installed in the insertion position (433) on the eyepiece baffle (43). As shown in Figures 6 and 7, hold the insertion handle (432) on the eyepiece baffle (43) and insert the positioning post (431) into the anti-rotation positioning groove (12) so that the eyepiece assembly (4) is inserted into the face shell (1). As shown in Figures 1 and 2, insert the neck clip (5) into the lower part of the back hair (3) and merge it with the face shell (1). Then insert the front hair (2) along the top of the face shell (1) into the back hair (3) to form a complete head shell.
[0018] Usage: The eyelid (11) can be opened and closed by moving it, and the range of opening and closing is shown in Figure 5. When the eyelid (11) is closed, it covers the eyepiece (41), but the eyepiece (41) remains suspended in the air and in a fixed position, and there is no movement interference between the two.
[0019] Replace the eyepiece: As shown in Figures 6 and 7, hold the plug handle (432) on the eyepiece baffle (43) and separate the eyepiece assembly (4) from the face shell (1), remove the eyepiece plate (42), replace the eyepiece (41), and repeat the installation steps.
[0020] This utility model is not limited to the specific embodiments described above. Any modifications, additions, or similar substitutions made to the described specific embodiments by those skilled in the art to which this utility model pertains, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims, shall all be within the scope of protection claimed by this utility model.
