Description

Technical Field

[0001] This utility model relates to the field of toy technology, and more particularly to an electronic control mechanism for a toy doll. Background Technology

[0002] Current dolls can rotate their limbs and heads, but this is done manually, resulting in limited play and low entertainment value. Therefore, patent application CN202223433162.3 proposes a toy doll where a second drive motor is connected to the head via a second gear set. The second gear set drives the head to swing, specifically by the forward and reverse rotation of the second drive motor to achieve left and right head movements. However, this method is prone to problems such as the motor failing to rotate properly, affecting the head's swinging function, and the motor easily jamming and burning out, leading to a shorter toy lifespan and a less than ideal user experience.

[0006] As a preferred embodiment, the eccentric part is configured as an eccentric column extending eccentrically outward along the outer surface of the drive member, and the inner wall of the follower cover is provided with a connecting groove that is inserted and connected to the eccentric column. The number of the connecting groove and the strip groove are both set to two opposite to each other.

[0007] As a preferred embodiment, the clutch gear structure includes a first gear and a second gear coaxially connected. The first gear has a gear ring inside, and the second gear has an elastic outer ring outside. The outer side of the elastic outer ring has a tooth block that can mesh with the gear ring.

[0008] As a preferred embodiment, the torso is further provided with a second drive assembly, which includes a second gearbox fixed inside the torso, a second motor and a second gear set fixed inside the second gearbox, and a fixing member rotatably connected to the torso. The second motor is drivenly connected to the second gear set, and the fixing member is coaxially fixed to one of the gears of the second gear set and driven to rotate by it. The fixing member is used to fix and connect the hand.

[0009] As a preferred embodiment, there are two of each of the second gear set and the fixed member. The second motor is a dual-axis motor. The two output shafts of the second motor are respectively fixedly connected to one of the gears located at the end of the two second gear sets. The other gear located at the end of the two second gear sets is respectively coaxially fixed to one of the fixed members. The two fixed members are rotatably connected to the two sides of the torso.

[0010] As a preferred embodiment, the second gearbox includes two fixedly connected housings, each housing containing a second gear set, each second gear set including a plurality of gears meshing sequentially, one of the gears in the second gear set being a clutch gear structure; the two housings are spliced ​​together to form a motor cavity for mounting the second motor, and each housing has a positioning block on its side wall opposite to the fixing member that can abut against it.

[0011] As a preferred embodiment, the fixing component includes a first fixing plate coaxially fixed to the second gear set and a second fixing plate coaxially fixed to the first fixing plate. The first fixing plate has a contact block corresponding to the positioning block on its rotating shaft. The contact block can abut against the positioning block during rotation.

By installing a follower cover outside the first gearbox, the outer wall of the follower cover is fixedly connected to the head. At the same time, the follower cover is connected to the drive component of the first gear set and is driven to rotate by it. The follower cover also has a strip-shaped groove that is movably fitted on the limiting block of the first gearbox. The cooperation between the strip-shaped groove and the limiting block can restrict the follower cover to rotate only in the extension direction of the strip-shaped groove. Thus, when the first motor starts and rotates continuously, the follower cover is driven by the drive component to make the head swing left and right on the torso. Compared with the existing structure that achieves left and right head swinging by reversing the motor, the first drive component provided by this utility model can achieve left and right head swinging without changing the direction of the first motor. It is less likely to cause the motor to jam and burn out. The structure has stronger stability and reliability, which can improve the service life of the toy and ensure a good user experience.

The terminology used in this specification of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the present invention.

[0025] Please refer to the following at the same time Figure 1-7 This embodiment provides an electronic control mechanism for a toy doll, including a torso 1 and a head 2. A first drive assembly 3 for driving the head 2 to rotate and a second drive assembly 4 for driving the hands to rotate are fixedly installed inside the torso 1. A third drive assembly 5 for driving the chin to swing is fixedly installed inside the head 2. The torso 1 has a first connecting hole 11 at the position corresponding to the neck, through which the first drive assembly 3 passes to securely connect to the head 2. The torso 1 has two second connecting holes 12 opposite each other at the positions corresponding to the arms, for rotatably connecting to the second drive assembly 4 so that the hands can be rotatably fixed to the torso 1. The torso 1 has two third connecting holes 13 opposite each other at the positions corresponding to the legs, for rotatably connecting to the legs so that they can be rotatably fixed to the torso 1.

[0026] It is understood that the torso 1 is constructed by splicing two shells together using methods such as screw fixing, snap-fit ​​fixing, and plug-in fixing. A battery compartment 14 is provided on the inner wall of one of the shells of the torso 1, used for installing and connecting batteries. A control circuit board 61 is also fixedly connected to the inner wall of one of the shells of the torso 1. The control circuit board 61 is electrically connected to the battery and the motors of the first drive assembly 3, the second drive assembly 4, and the third drive assembly 5, respectively, and is used to control the corresponding motors to start and achieve the corresponding functions upon receiving control signals. The control circuit board 61 integrates a master switch 62 for controlling the opening or closing of the game. In some embodiments, the control circuit board 61 may also integrate electrical components such as speakers, microphones, touch switches, and remote control switches to achieve corresponding functions, such as voice control, touch control, and remote control.

[0027] It is understandable that the head 2 is also composed of two shells that are spliced ​​together by means of screw fixing, snap fixing, plug fixing, etc. One of the shells of the head 2 has a chin hole 21. The chin hole 21 is used to pass through the chin piece of the third drive component 5 so that it can swing on the head 2, thereby simulating the action of the doll opening its mouth to speak.

[0028] The first drive assembly 3 includes a first gearbox 31 fixed inside the body 1, a first motor 32 and a first gear set 33 fixed inside the first gearbox 31, and a follower cover 34 sleeved on the first gearbox 31. The first gearbox 31 is constructed by splicing two housings together using screws, snap-fit ​​fasteners, or plug-in fasteners. A limiting block 311 protrudes outward from the outer wall of the first gearbox 31 and is movably connected to the inner wall of the follower cover 34. The first motor 32 is electrically connected to the control circuit board 61 and is driven by the first gear set 33, enabling it to drive the first gear set 33 to rotate simultaneously when the first motor 32 is controlled to start. The first gear set 33 includes multiple gears meshing sequentially. In this embodiment, the first gear set 33 consists of five gears meshing sequentially, with the two end gears being the first end gear 331 and the second end gear 332. The first end gear 331 is fixed to the shaft of the first motor 32. The second end gear 332 is coaxially fixedly connected to two driving members 333. It can be understood that, in order to increase the circumferential connection strength between the second end gear 332 and the driving members 333, the shaft of the second end gear 332 is set as a polygonal prism structure. In other embodiments, the first gear set 33 may specifically consist of at least two gears meshing in sequence, wherein the shaft of the second end gear 332 may also be set as a cylindrical structure, in which case the driving members 333 can be tightly fitted onto the cylinder.

[0029] It is understood that each driving component 333 is rotatably connected to the outside of the first gearbox 31, and each driving component 333 is provided with an eccentric part 3331 for connecting to and driving the follower cover 34 to rotate. In this embodiment, the eccentric part 3331 is configured as an eccentric column extending eccentrically outward along the outer surface of the driving component 333. At this time, the inner wall of the follower cover 34 is provided with a connecting groove 341 that is inserted and connected to the eccentric column. When the driving component 333 rotates, the follower cover 34 can be driven to rotate on the first gearbox 31 through the cooperation of the eccentric column and the connecting groove 341. It is understood that the follower cover 34 passes through the first connecting hole 11 and has a head 2 fixedly connected to its outer wall. The inner wall of the follower cover 34 is also provided with a strip-shaped sliding groove 342, which is movably sleeved on the limiting block 311. The cooperation between the strip groove 342 and the limiting block 311 restricts the follower cover 34 to rotate only in the extending direction of the strip groove 342. Therefore, when the first motor 32 starts and rotates continuously, the follower cover 34, driven by the drive member 333, can cause the head 2 to swing left and right on the torso 1. To improve the stability of the follower cover 34 on the first gearbox 31, the number of connecting grooves 341 and strip grooves 342 in the follower cover 34 are both set to two oppositely arranged. In other embodiments, the eccentric portion 3331 can also be adjusted to an eccentric slot structure eccentrically arranged on the outer surface of the drive member 333. In this case, the inner wall of the follower cover 34 is provided with a plug structure that can be inserted into the eccentric slot. The number of connecting grooves 341 and strip grooves 342 can be adjusted to one or more as needed.

[0030] The second drive assembly 4 includes a second gearbox 41 fixed inside the body 1, a second motor 42 and a second gear set 43 fixed inside the second gearbox 41, and a fixing member 44 rotatably connected to the second connecting hole 12. In this embodiment, there are two second gear sets 43 and two fixing members 44. The second motor 42 is a dual-axis motor. In this case, the second gearbox 41 includes two housings 411 fixedly connected. Each housing 411 is constructed by splicing two shells together through screw fixing, snap fixing, plug fixing, etc., and a second gear set 43 is fixedly installed inside each housing 411. The two housings 411 are spliced ​​together through screw fixing, snap fixing, plug fixing, etc. to form a motor cavity 412 for installing the second motor 32. It can be understood that each housing 411 has a positioning block 4111 on the side wall opposite to the fixing member 44, which can be contacted and connected to it, in order to limit the rotation angle of the fixing member 44. In other embodiments, the number of second motors 42 can also be adjusted to two. In this case, a gear of a second gear set 43 is fixedly connected to the shaft of each second motor 42, which is used to drive the corresponding second gear set 43 to rotate. Moreover, the positioning block 4111 may not be provided on the side wall of each housing 411.

[0031] The second motor 42 is electrically connected to the control circuit board 61 and is driven by two second gear sets 43. When the second motor 42 is started under control, it can simultaneously drive the two second gear sets 43 to rotate. Each second gear set 43 includes multiple gears meshing sequentially. In this embodiment, the second gear set 43 consists of five gears meshing sequentially, with the two end gears being the third end gear 431 and the fourth end gear 432. The third end gear 431 is fixed to one of the shafts of the second motor 42, and the fourth end gear 432 is coaxially fixed to a fixing member 44. To increase the circumferential connection strength between the fourth end gear 432 and the fixing member 44, the shaft of the fourth end gear 432 is configured as a polygonal prism structure. In other embodiments, the second gear set 43 may specifically consist of at least two gears meshing sequentially, and the shaft of the fourth end gear 432 may also be configured as a cylindrical structure, in which case the fixing member 44 can be tightly fitted onto the cylinder.

[0032] Two fixing members 44 are rotatably connected to the second connecting holes 12 on both sides of the torso 1. Each fixing member 44 includes a first fixing plate 441 coaxially fixed to the fourth end gear 432 and a second fixing plate 442 coaxially fixed to the first fixing plate 441. In this embodiment, the rotating shaft of the first fixing plate 441 is provided with a contact block 4411 corresponding to the positioning block 4111. The contact block 4411 can abut against the positioning block 4111 during rotation. The rotating shaft end of the first fixing plate 441 forms a fixing block 4412. The second fixing plate 442 has a fixing groove 4421 with a matching shape on the side opposite to the fixing block 4412 to achieve the purpose of fixing the second fixing plate 442 to the first fixing plate 441. The second fixing plate 442 is externally placed on the torso 1 and used for fixed connection with the hand. In other embodiments, if the housing 411 does not have a positioning block 4111, then the first fixing plate 441 does not have a corresponding contact block 4411.

[0033] In this embodiment, both the first gear set 33 and the second gear set 34 have a gear configured as a clutch gear structure. The clutch gear structure includes a first gear 101 and a second gear 102 coaxially connected. The first gear 101 has a gear ring 1011 inside, and the second gear 102 has an elastic outer ring 1021 outside. A tooth block 1022, which meshes with the gear ring 1011, is located outside the elastic outer ring 1021. It is understood that the structure of the elastic outer ring 1021 gives the tooth block 1022 the ability to move elastically. Therefore, when the tooth block 1022 is not affected by external force, it can mesh with the gear ring 1011 and rotate with it. When the tooth block 1022 is immobilized by external force, it can rotate relative to the gear ring 1011, thereby preventing the motor from jamming and burning out. In other embodiments, the first gear set 33 and the second gear set 34 may not have a clutch gear structure, and the clutch gear structure can be replaced by other existing structures.

[0034] The third drive assembly 5 includes a third gearbox 51 fixed inside the head 2, a third motor 52 and a third gear set 53 fixed inside the third gearbox 51, and a chin piece 54 externally mounted on the head 2. The third gearbox 51 is constructed by splicing two housings together using screws, snap-fit ​​fasteners, or plug-in connections. The third motor 52 is electrically connected to the control circuit board 61 and is driven by the third gear set 53, enabling the third gear set 53 to rotate simultaneously when the third gear 52 is controlled to start. The third gear set includes multiple gears meshing sequentially. In this embodiment, the third gear set 53 consists of five gears meshing sequentially, with the two end gears being the fifth end gear 531 and the sixth end gear 532. The fifth end gear 531 is fixed to the shaft of the third motor 52, and the sixth end gear 532 is coaxially fixed to the chin piece 54. It is understood that to increase the circumferential connection strength between the sixth end gear 532 and the chin piece 54, the shaft of the sixth end gear 532 is designed as a polygonal prism structure. In other embodiments, the third gear set 53 may specifically consist of at least two gears meshing in sequence, wherein the shaft of the sixth end gear 532 may also be configured as a cylindrical structure, in which case the chin piece 54 can be tightly fitted onto the cylinder.

[0035] It is understood that the chin piece 54 includes a bracket 541 and a main body 542. The two connecting feet 5411 of the bracket 541 are coaxially fixed to the sixth end gear 532. On the other side of the bracket 541 opposite to the connecting feet 5411, there is a fixing foot 5412. The fixing foot 5412 is provided with a guide block 5413. The fixing shaft 5421 of the main body 542 is inserted and fixed to the fixing foot 5412, and the fixing shaft 5421 is provided with a guide groove 5422 that matches the guide block 5413, which serves to position and quickly fix the chin piece. In some embodiments, the chin piece 54 and the head 2 can also be connected by an elastic structure such as a torsion spring.

[0036] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
