Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to a doll eye device. Background Technology

[0002] As the "windows to the soul" of a doll, eyes are designed in a variety of ways to attract players, including light-up eyes, LCD screen eyes, and eyes that can close and open. However, current technology still has certain limitations in simulating realistic and natural eye-closing and opening movements.

[0003] To achieve the effect of a doll's eyes closing and opening, most doll eye structures use a gravity lever principle based on counterweights. While the structure is simple and allows the eyes to close automatically when the doll is lying down, relying on counterweights to achieve the gravity lever effect results in the eyelids closing too quickly, lacking realistic and natural closing and opening movements. Furthermore, the movement of the counterweights can cause them to collide with the doll, generating noise and limiting the doll's realism, thus affecting the player's gaming experience.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a doll eye device to solve the technical problem that existing doll eye closing structure designs have defects, relying on counterweights to achieve a gravitational lever effect, resulting in excessively fast eyelid closing speed, failing to achieve realistic and natural eye closing and opening movements, and affecting the doll's realism and gaming experience. The various technical effects of the preferred technical solution provided by this utility model are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention provides a doll eye device, including a housing, and an eyelid, a power lever, a transmission component and a damping component disposed within the housing;

[0008] The number of eyelids is two, and they are respectively set in the eye socket of the shell;

[0009] The transmission assembly includes a transmission shaft and a transmission gear. The transmission shaft is connected to the two eyelids respectively, and the transmission gear is sleeved on the transmission shaft.

[0010] The power lever includes a sector tooth and a flat plate structure connected in sequence. The sector tooth is connected to the housing via a rotating shaft. The rotating shaft is eccentrically disposed on the sector tooth. The sector tooth meshes with the transmission gear and the damping assembly, respectively.

[0011] Preferably, the central axis of the sector teeth does not coincide with the central axis of the flat plate structure, so that the power lever forms an asymmetrical structure.

[0012] Preferably, the transmission assembly further includes a first connecting post and a second connecting post, which are respectively disposed on opposite sides of the two eyelids. The first connecting post is a square post, and the second connecting post has a square groove. The square post and the square groove are inserted into each other. The transmission gear is located between the two eyelids and has a square hole that is adapted to the square post.

[0013] Preferably, the outer peripheral wall of the second connecting column is provided with a first upper limit protrusion and a first lower limit protrusion, and the housing is provided with a second upper limit protrusion and a second lower limit protrusion. The second upper limit protrusion is located on the rotation path of the first upper limit protrusion, and the second lower limit protrusion is located on the rotation path of the first lower limit protrusion.

[0014] Preferably, it also includes eyeballs, the left eye and the right eye are respectively connected to the housing via connectors, and are respectively provided corresponding to the left eye socket and the right eye socket; the back of the left eye and the right eye are provided with grooves for the transmission shaft to pass through.

[0015] Preferably, fur pressing components are respectively provided on the left eye socket and the right eye socket. The fur pressing component includes a pressing groove and a pressing member. A first slot is provided on the pressing groove, and a first hook is provided on the pressing member. The first hook engages with the first slot.

[0016] Preferably, a positioning protrusion is provided on the outer wall surface of the pressure groove, and the positioning protrusion has a pointed tip.

[0017] Preferably, the damping assembly includes damping teeth, and the number of damping teeth is at least two. Each damping tooth includes an input tooth portion and an output tooth portion. The diameter of the input tooth portion is smaller than the diameter of the output tooth portion. The input tooth portion meshes with the output tooth portion of the sector tooth or an adjacent damping tooth.

[0018] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0019] This invention effectively avoids the defects in the existing doll eye closure structure design, which relies on counterweights to achieve a gravitational lever effect. This results in excessively fast eyelid closing, failing to achieve realistic and natural eye closing and opening movements, thus affecting the doll's realism and gaming experience. This invention provides a doll eye device, including a housing, and eyelids, a power lever, a transmission component, and a damping component disposed within the housing. There are two eyelids, each corresponding to an eye socket in the housing. The transmission component includes a transmission shaft and transmission gears. The transmission shaft connects to both eyelids, and the transmission gears are mounted on the transmission shaft. The power lever includes sector teeth and a flat plate structure. The sector teeth are connected to the housing via a rotating shaft, which is eccentrically positioned on the sector teeth. The sector teeth mesh with the transmission gears and the damping component. When the doll transitions from a standing to a lying position, gravity acts on the lever, generating a gravitational torque that causes the lever to rotate clockwise around its axis. The sector teeth drive the transmission gear, which in turn rotates the eyelids counter-clockwise, resulting in the eye-closing action. When the doll transitions from a lying to a standing position, the change in posture alters the direction of gravity on the lever. The gravitational torque causes the lever to rotate counter-clockwise around its axis, again driving the sector teeth to rotate the transmission gear and causing the eyelids to rotate clockwise, resulting in the eye-opening action. Furthermore, the engagement of the sector teeth with a damping component provides appropriate resistance as the teeth rotate, controlling the eyelid rotation speed. This makes the eye-closing and opening actions more natural, smooth, and fluid, enhancing the doll's realism and the overall gaming experience. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-4 As shown, the present invention provides a doll eye device, including a housing 1, and eyelids 2, a power lever 3, a transmission component, and a damping component disposed within the housing 1; there are two eyelids 2, which are respectively disposed corresponding to the eye sockets of the housing 1; the transmission component includes a transmission shaft 4 and a transmission gear 5, the transmission shaft 4 is connected to the two eyelids 2 respectively, and the transmission gear 5 is sleeved on the transmission shaft 4; the power lever 3 includes a sector tooth 301 and a flat plate structure 302 connected in sequence, the sector tooth 301 is connected to the housing 1 through a rotating shaft 303, the rotating shaft 303 is eccentrically disposed on the sector tooth 301, and the sector tooth 301 meshes with the transmission gear 5 and the damping component respectively.

[0029] When the doll lies down, gravity acts on the power lever 3, and the gravitational torque drives the power lever 3 to rotate clockwise around the rotation axis 303. The sector tooth 301 drives the transmission gear 5 to rotate accordingly, and drives the two eyelids 2 to rotate synchronously in the counterclockwise direction, thus realizing the action of closing the eyes.

[0030] When the doll changes from a lying position to a standing position, the direction of gravity acting on the power lever 3 changes due to the change in posture. This causes the gravitational torque to drive the power lever 3 to rotate counterclockwise around the rotation axis 303. The sector tooth 301 drives the transmission gear 5 to rotate accordingly, and drives the two eyelids 2 to rotate synchronously in a clockwise direction, thus realizing the action of opening the eyes.

[0031] In addition, since the sector tooth 301 meshes with the damping component, the damping component provides appropriate resistance when the sector tooth 301 rotates, thereby controlling the rotation speed of the eyelid 2, so that the closing and opening movements of the eyelid 2 are more natural, smooth and fluid, improving the realism of the doll and the gaming experience.

[0032] Furthermore, the housing 1 includes a front housing 101 and a rear housing 102. The top and bottom of the front housing 101 and the rear housing 102 are detachably connected by snap-fit ​​assemblies, and the two together enclose a receiving cavity for accommodating the eyelid 2, the power lever 3, the transmission assembly, and the damping assembly. The eye socket is formed on the front housing 101.

[0033] The snap-fit ​​assembly includes a second slot 1011 and a second hook 1021. The second slot 1011 is respectively disposed at the top and bottom of the front shell 101, and the second hook 1021 is correspondingly disposed at the top and bottom of the rear shell 102. The front shell 101 and the rear shell 102 are snapped together by the snap-fit ​​engagement between the second hook 1021 and the second slot 1011.

[0034] As an optional implementation, the central axis of the sector tooth 301 and the central axis of the flat plate structure 302 do not coincide, so that the power lever 3 forms an asymmetrical structure.

[0035] Furthermore, the rotating shaft 303 is located on the side of the sector tooth 301 near the eyelid 2.

[0036] This design optimizes the rotation effect of the power lever 3 under gravity, allowing the power lever 3 to achieve rotation with only a small torque. That is, when the doll's posture changes slightly in the direction of rotation of the power lever 3, the power lever 3 can easily rotate to drive the eyelids to perform the corresponding opening or closing movements.

[0037] As an optional implementation, the transmission assembly further includes a first connecting post 6 and a second connecting post 7, which are respectively disposed on opposite sides of the two eyelids 2. The first connecting post 6 is a square post, and the second connecting post 7 has a square groove 701, which is inserted into the square post. The transmission gear 5 is located between the two eyelids 2 and has a square hole, which is adapted to the square post.

[0038] Furthermore, the first connecting post 6 has a connecting hole for the transmission shaft 4 to pass through, and the two ends of the eyelid 2 have through holes 201 for the transmission shaft 4 to pass through, so that the transmission shaft 4 passes through the first connecting post 6, the two eyelids 2 and the front shell 101 to form a rotatable connection.

[0039] The first connecting post 6 passes through the square hole of the transmission gear 5 and is inserted into the square groove 701 of the second connecting post 7 to make the first connecting post 6, the transmission gear 5 and the second connecting post 7 firmly connected, preventing relative rotation between the three, so that the rotation of the two eyelids 2 remains synchronized and stable.

[0040] The rotation of the sector tooth 301 drives the transmission gear 5 to rotate the first connecting post 6. Since the first connecting post 6 and the second connecting post 7 are inserted and engaged, the second connecting post 7 will also rotate synchronously, thereby driving the two eyelids 2 to rotate synchronously.

[0041] As an optional implementation, the outer peripheral wall of the second connecting post 7 is provided with a first upper limit protrusion 702 and a first lower limit protrusion 703, and the front shell 101 is provided with a second upper limit protrusion 1012 and a second lower limit protrusion 1013. The second upper limit protrusion 1012 is located on the rotation path of the first upper limit protrusion 702, and the second lower limit protrusion 1013 is located on the rotation path of the first lower limit protrusion 703.

[0042] When the first upper limit protrusion 702 abuts against the second upper limit protrusion 1012, the second connecting post 7 cannot continue to rotate upward, thus limiting the upper limit of the rotation range of the eyelid 2 and preventing excessive rotation.

[0043] When the first lower limit protrusion 703 abuts against the second lower limit protrusion 1013, the second connecting post 7 cannot continue to rotate downwards, thus limiting the upper limit of the rotation range of the eyelid 2 and preventing excessive rotation.

[0044] As an optional implementation, it also includes an eyeball 8, which is connected to the front shell 101 via a connector 14 and is respectively provided for the eye socket; a groove 801 is provided on the back of the eyeball 8 for the transmission shaft 4 to pass through.

[0045] As an optional implementation, fur pressing components are respectively provided on the eye socket. The fur pressing component 10 includes a pressing groove 9 and a pressing member 10. A first slot 901 is provided on the pressing groove 9, and a first hook member 1001 is provided on the pressing member 10. The first hook member 1001 engages with the first slot 901.

[0046] Furthermore, there are multiple first slots 901, which are arranged at intervals along the circumference of the pressure groove 9. First hooks 1001 are provided corresponding to the first slots 901.

[0047] The first hook 1001 engages with the first slot 901 to secure the fur between the slot 9 and the slot 10, preventing the fur around the eyes from separating from the front shell 101.

[0048] As an optional implementation, a plurality of positioning protrusions 902 are provided on the outer wall surface of the pressure groove 9, and the positioning protrusions 902 have sharp points.

[0049] The positioning protrusion 902 can be easily inserted into the fur to further secure it.

[0050] As an optional implementation, the damping assembly includes damping teeth, with at least two damping teeth. Each damping tooth includes an input tooth portion and an output tooth portion. The diameter of the input tooth portion is smaller than the diameter of the output tooth portion. The input tooth portion meshes with the output tooth portion of the sector tooth 301 or an adjacent damping tooth.

[0051] Furthermore, the resistance torque provided by the damping component is less than the gravitational torque on the power lever 3, so that the damping component can slow down the rotation speed of the power lever 3, prevent the power lever 3 from colliding with the housing 1 when the attitude changes rapidly, and avoid making noise. At the same time, the damping component will not completely stop the rotation of the power lever 3.

[0052] Furthermore, the damping assembly includes a first damping tooth 11, a second damping tooth 12, and a third damping tooth 13. The first input tooth portion 1101 of the first damping tooth 11 meshes with the sector tooth 301, the first output tooth portion 1102 of the first damping tooth 11 meshes with the second input tooth portion 1201 of the second damping tooth 12, and the second output tooth portion 1202 of the second damping tooth 12 meshes with the third input tooth portion 1301 of the third damping tooth 13.
