DETAILED DESCRIPTION

[0029] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0030] like Figure 1-Figure 10As shown, the automatic rotation and translation device of the child safety seat based on voice control provided in this embodiment includes a rotating disk 1, a first worm wheel 2 and a first worm 3 which are meshed with each other are arranged inside the rotating disk 1, a rotating motor 4 is arranged at one end of the first worm 3, a translation seat 5 is arranged on the rotating disk 1, a lead screw 6 is arranged in the translation seat 5, a second worm wheel 7 is arranged on the lead screw 6, a second worm wheel 7 is meshed with a second worm 8, and the second worm 8 is connected to the translation motor 9.

[0031] After the rotating motor 4 is started, it drives the first worm 3 to rotate, so that the first worm wheel 2 rotates and drives the rotating disk 1 to rotate, completing the rotation action; after rotating 90 degrees, the translation operation can be performed. After the translation motor 9 is started, it drives the second worm 8 to rotate, so that the second worm wheel 7 rotates and the lead screw 6 and the translation seat 5 move to complete the translation action. The rotating motor 4 and the translation motor 9 both use 12V DC Hall motors.

[0032] In this embodiment, if Figure 3 As shown, a seat body 10 is arranged on the translation seat 5, and the translation seat 5 is connected to the seat body 10 through an axis, a base 11 is arranged under the rotating disk 1, and the rotating disk 1 is rotatably connected to the base 11, a voice main control board 12 is arranged inside the seat body 10, and a voice receiving component 13 and a voice output component 14 are arranged inside the base 11. Control instructions are input through voice. After receiving the instruction, the voice receiving component 13 sends the signal to the voice main control board 12, and the voice main control board 12 sends the instruction signal to the corresponding rotating motor 4 or the translation motor 9 to complete the instruction action. Through voice control, the possibility of manual operation errors is reduced, and the safety of children's riding process is ensured.

[0033] In this embodiment, if Figure 2 As shown, the base 11 is provided with a first contact micro switch 15 directly behind the connection position with the rotating disk 1, and a second contact micro switch 16 is provided at one end of the screw rod 6. The first contact micro switch 15 and the second contact micro switch 16 provide in-position feedback to the voice main control board 12, ensuring that the rotating motor 4 and the translation motor 9 accurately complete the adjustment after receiving the end command, thereby further improving the accuracy and reliability of the adjustment.

The large reduction gear 17 and the small reduction gear 18 are meshed with each other. The design of the reduction gear makes the rotation action more delicate, thereby improving the responsiveness and durability of the entire system.

[0035] In this embodiment, if Figure 1 As shown, a support shell 19 is provided on the outer side of the second worm wheel 7 and the second worm 8, and the support shell 19 is fixed on the rotating disk 1 to provide support.

[0036] In this embodiment, if Fig. 9 and Fig.10 As shown, unlocking handles 20 are provided on both sides of the rotating disk 1, a connecting rotating disk 21 is provided above the first worm gear 2, the unlocking handle 20 is connected to the connecting rotating disk 21 through a first connecting rod 22 and a second connecting rod 23, a wedge block 24 is provided on the second connecting rod 23, a wedge groove 25 is provided on the connecting rotating disk 21, a connecting frame 26 is provided above the second connecting rod 23, cylindrical pins 27 are provided at both ends of the bottom surface of the connecting frame 26, the first worm gear 2 and the connecting rotating disk 21 are respectively provided with a first cylindrical pin hole 28 and a second cylindrical pin hole 29, the connecting rotating disk 21 is provided above the first worm gear 2 and is connected to the first worm gear 2 through the cylindrical pin 27, the first worm gear 2. The connecting turntable 21 and the connecting frame 26 are connected by an axis. When the power-off system cannot work, pull the unlocking handle 20 outward to make the second connecting rod 23 move outward and upward along the hypotenuse of the wedge-shaped groove 25, so that the connecting frame 26 and the cylindrical pin 27 above the second connecting rod 23 also move upward. At this time, the first worm gear 2 is disengaged from the connecting turntable 21, and the rotating disk 1 can rotate freely, so that the angle of the seat body 10 can be manually adjusted. After rotating to a suitable angle, release the unlocking handle 20, the cylindrical pin 27 is reset, the connecting turntable 21 and the first worm gear 2 are reconnected, and are locked by the first worm 3, so that the position of the seat body 10 is fixed.

[0037] In summary, in this embodiment, the worm gear structure and the screw mechanism are used to achieve precise adjustment, which not only improves the convenience of operation, but also ensures the safety and comfort of children. Parents can easily control the position of the seat body 10 through simple voice commands without manual intervention, reducing the risk of misoperation. The device has strong flexibility and applicability and can adapt to different riding environments. At the same time, by being equipped with a contact micro switch, the device can provide in-place feedback to the voice main control board 12 to ensure that the rotary motor 4 and the translation motor 9 accurately complete the adjustment after receiving the end command. This design highly guarantees the safety of children and embodies the perfect integration of modern technology and parenting needs; the manual unlocking part provided provides important safety advantages, especially in emergency situations when power failure or the voice control system cannot work properly. Through the unlocking handle 20, the connecting rod system, and the cooperation of the connecting turntable 21 and the cylindrical pin 27, the user can easily manually intervene and adjust the position of the seat body 10, thereby enhancing the operational reliability and convenience of the seat body 10. This simple mechanical design is easy to maintain and suitable for various environments, improving the applicability and flexibility of the child safety seat while maintaining a high level of safety performance.
