Description

Technical Field

[0001] The invention relates to a voice-controlled electric rotating structure of a child seat and a control method thereof. Background Art

[0002] A child seat, also known as a child restraint system, is a seat designed for children of different ages (or weights), installed in a car, and can effectively improve the safety of children riding in a car. The European regulation ECE R129 defines a child safety seat as: a child safety protection system that can be fixed to a motor vehicle and consists of a seat belt assembly or flexible components, an adjustment mechanism, accessories, etc. It can be combined with additional devices such as a portable crib, an infant carrier, an auxiliary seat or a collision protection device. It can reduce the impact force on the child and limit the child's body movement in the event of a car collision or sudden deceleration to reduce their injuries and ensure the child's safety in the car. It is widely used. In the existing technology, when using a child seat in a car, it is generally necessary to manually drag the handle iron plate when adjusting the seat rotation, which is very inconvenient to use and cannot quickly and effectively realize the seat rotation function. Therefore, the present application proposes a child seat voice-controlled electric rotation structure and a control method thereof to solve the above problems. Summary of the Invention

[0003] The object of the present invention is to provide a voice-controlled electric rotating structure of a child seat and a control method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a voice-controlled electric rotating structure for a child seat, the child seat comprising a base and a turntable for mounting a seat body, the turntable being rotatably disposed on a mounting shaft within the base, the electric rotating structure comprising a turntable driving mechanism and a turntable limiting mechanism disposed within the base;

[0005] The turntable drive mechanism is close to the mounting shaft and is located below the turntable. A plurality of gear slots are evenly spaced on the edge of the turntable. The turntable drive mechanism drives the turntable to rotate at even intervals according to the positions of the gear slots.

[0006] The turntable limiting mechanism includes a pin piece, which is slidably connected to the upper cover of the base. When the turntable is rotated and adjusted to a suitable gear, the pin piece is engaged with the gear slot of the turntable to limit and lock it.

[0007] Furthermore, the turntable drive mechanism includes a drive motor, a driving gear mounted on the output shaft of the drive motor, a transmission belt, and a driven gear arranged at the bottom of the turntable. The drive motor is installed in the base and is located behind the mounting shaft. The transmission belt is respectively sleeved on the driving gear of the motor output shaft and the driven gear at the bottom of the turntable, serving as a direct transmission member between the driving gear and the driven gear.

[0008] The turntable limiting mechanism also includes a winding motor, a winding disk installed on the output shaft of the winding motor, a traction rope and a spring arranged under the pin piece. The winding motor is installed in the base and close to the pin piece. One end of the spring is connected to the pin piece, and the other end of the spring is connected to the upper cover of the base. One end of the traction rope is fixed in the groove of the winding disk, and the other end of the traction rope is connected to the pin piece. The pin piece is controlled to slide in and out of the gear slot of the turntable by the tension of the traction rope and the restoring force of the spring contraction.

[0009] Furthermore, the turntable is provided with a positioning disk below the driven gear, and the positioning disk is provided with through holes corresponding to the number and position of the gear slots, each through hole is a gear position, and a photoelectric switch A is provided on one side of the positioning disk. Two notches are provided on the winding disk chassis on the winding motor output shaft, one notch is the starting position, and the other notch is the end position. A photoelectric switch B is also provided on one side of the winding disk chassis. The driving motor, photoelectric switch A, winding motor and photoelectric switch B are all connected to the voice control module, and the voice control module is also installed in the base;

[0010] The voice control module is used to control the operation of the drive motor and the winding motor according to voice commands. The photoelectric switch A is used to stop the drive motor when the drive motor drives the turntable to rotate and each gear position of the positioning disk below the turntable rotates to the photoelectric switch A, so that the distance the drive motor drives the turntable to rotate each time is the same as the rotation distance between adjacent gear positions. The photoelectric switch B is used to stop the winding motor when the winding motor drives the winding disk to rotate and the starting position notch and the end position notch on the winding disk rotate to the photoelectric switch B, so that the winding disk rotates between the starting position notch and the end position notch.

[0011] Furthermore, the photoelectric switch A and the photoelectric switch B are both normally closed, and their structures are both U-shaped, with the upper port of the switch emitting light and the lower port receiving light;

[0012] The photoelectric switch A is arranged at the edge of the positioning plate. The light emitted by the upper port of the photoelectric switch A is blocked by the positioning plate and the switch is in a closed state. When the through hole of the positioning plate is rotated to the position of the photoelectric switch A, the light emitted by the upper port of the photoelectric switch A is received by the lower port, so that the photoelectric switch A is disconnected and the driving motor is stopped.

[0013] The photoelectric switch B is arranged on the edge of the winding reel chassis. The light source emitted by the upper port of the photoelectric switch B is blocked by the chassis of the winding reel and the switch is in a closed state. When the gap of the winding reel rotates to the photoelectric switch B, the light source emitted by the upper port of the photoelectric switch B is received by the lower port, causing the electric switch B to disconnect and stop the winding motor.

[0014] Furthermore, the number of the gear slots arranged at equal intervals on the turntable is at least 4, and the number of the corresponding through holes on the positioning plate is also at least 4, and each through hole is arranged near the edge of the positioning plate.

[0015] Furthermore, the two notches on the winding disk are set at the edge of the chassis, and the photoelectric switch B is set at the starting position notch. When the end position notch of the winding disk rotates to the photoelectric switch B, the winding traction line of the winding disk pulls the pin out of the gear slot.

[0016] Furthermore, a mounting groove is provided at the front end of the upper cover of the base, and the pin piece is slidably provided in the mounting groove of the upper cover.

[0017] Furthermore, each end of the traction rope is connected to a pin rod, one end of the traction rope is embedded in the reel groove and connected to it, and the other end of the traction rope is inserted into the front end of the pin piece and then connected to the pin rod for blocking, thereby connecting the traction rope to the pin piece;

[0018] A steering wheel is also provided on the front side of the pin piece, and the steering wheel is rotatably provided on the front end of the upper cover of the base. The traction rope passes around the steering wheel to bend the rope body, and the winding motor is provided on one side of the pin piece.

[0019] A method for using a voice-controlled electric rotating structure of a child seat comprises the following steps:

[0020] Step (A): issuing a voice command: "rotate left / right" or "rotate left / right side", and the voice control module controls the operation of the driving motor and the winding motor according to the voice command;

[0021] Step (B): First, the winding motor is controlled to operate, and the output shaft of the winding motor drives the winding disc to rotate from the starting position to the end position, winding the traction rope and pulling the pin out of the gear slot of the turntable;

[0022] Step (C): Secondly, control the driving motor to operate, the output shaft of the driving motor drives the driving gear to rotate, and drives the turntable and the seat body to rotate left or right to a gear position through the transmission belt and the driven gear;

[0023] Step (D), finally, the winding motor is controlled to operate again, driving the winding disc to rotate from the end position to the initial position for reset, so that the traction rope no longer pulls the pin piece, and the pin piece is reinserted into the gear slot by the restoring force of the spring;

[0024] Step (E): When further adjustment is required, repeat steps (A) to (D) to achieve voice-controlled rotation adjustment of the seat.

[0025] Compared with the existing technology, the present invention controls the operation of the driving motor and the winding motor through a voice control module. When the winding motor is running, it is used to control the pin piece to enter and exit the gear slot on the turntable. When the driving motor is running, it is used to drive the turntable to rotate according to the gear. According to the voice command, the turntable and the seat on the turntable are controlled to rotate one gear until the seat is adjusted to the appropriate position. There is no need to manually drag the handle iron sheet and rotate the seat, and the seat rotation adjustment can be performed quickly, effectively and conveniently.

[0041] In this embodiment, the turntable 2 is provided with a positioning disk 202 below the driven gear 304, and the positioning disk 202 is provided with through holes 203 corresponding to the number and position of the gear slots 201, each through hole 203 is a gear position, and a photoelectric switch A5 is further provided on one side of the positioning disk 202. Two notches 4031 are provided on the chassis of the winding disk 403 on the output shaft of the winding motor 402, one notch 4031 is a starting position, and the other notch 4031 is an end position.

The driving motor 301, the photoelectric switch A5, the winding motor 402 and the photoelectric switch B6 are all connected to the voice control module 7, and the voice control module 7 is also installed in the base 1;

[0042] Among them, another embodiment of the notch 4031 on the winding disk 403 is as follows: a notch 4031 is set on the bottom plate of the winding disk 403, and the notch 4031 is both the starting position and the end position. When the notch 4031 rotates to the photoelectric switch B6 when the winding disk 403 rotates, the winding motor 402 stops, and the traction rope 404 is wound or released by the forward or reverse rotation of the winding motor 402;

[0043] The voice control module 7 is used to control the operation of the drive motor 301 and the winding motor 402 according to voice commands. The photoelectric switch A5 is used to stop the drive motor 301 when the drive motor 301 drives the turntable 2 to rotate and each gear position of the positioning disk 202 below the turntable 2 rotates to the photoelectric switch A5, so that the distance that the drive motor 301 drives the turntable 2 to rotate each time is the same as the rotation distance between adjacent gear positions. The photoelectric switch B6 is used to stop the winding motor 402 when the winding motor 402 drives the winding disk 403 to rotate and the starting position notch 4031 and the end position notch 4031 on the winding disk 403 rotate to the photoelectric switch B6, so that the winding disk 403 rotates between the starting position notch 4031 and the end position notch 4031.

[0044] In this embodiment, the photoelectric switch A5 and the photoelectric switch B6 are both normally closed and have a U-shaped structure. The upper port of the switch emits light and the lower port receives light.

[0045] The photoelectric switch A5 is arranged at the edge of the positioning plate 202. The light emitted by the upper port of the photoelectric switch A5 is blocked by the positioning plate 202 and the switch is in a closed state. When the through hole 203 of the positioning plate 202 rotates to the photoelectric switch A5, the light emitted by the upper port of the photoelectric switch A5 is received by the lower port, causing the photoelectric switch A5 to be disconnected and stop driving the motor 301.

[0046] The photoelectric switch B6 is set on the edge of the chassis of the winding reel 403. The light source emitted by the upper port of the photoelectric switch B6 is blocked by the chassis of the winding reel 403 and the switch is in a closed state. When the notch 4031 of the winding reel 403 rotates to the photoelectric switch B6, the light source emitted by the upper port of the photoelectric switch B6 is received by the lower port, causing the electric switch B to disconnect and stop the winding motor 402.

When the seat rotation is adjusted, one gear position is adjusted, that is, the seat is rotated 90 degrees to the left or right.

[0048] In this embodiment, the two notches 4031 on the winding disk 403 are set at the edge of the chassis, and the photoelectric switch B6 is set at the starting position notch 4031. When the end position notch 4031 of the winding disk 403 rotates to the photoelectric switch B6, the winding disk 403 winds up the traction line to pull the pin piece 401 out of the gear slot 201.

[0049] In this embodiment, a mounting groove 103 is provided at the front end of the upper cover 102 of the base 1 , and the pin piece 401 is slidably disposed in the mounting groove 103 of the upper cover 102 .

[0050] In this embodiment, a pin is connected to each end of the traction rope 404. One end of the traction rope 404 is connected to the reel 403 through the pin embedded in the groove of the reel. The other end of the traction rope 404 is inserted into the front end of the pin piece 401 and then connected to the pin to block it, thereby connecting the traction rope 404 to the pin piece 401.

[0051] A steering wheel 8 is also provided on the front side of the pin piece 401, and the steering wheel 8 is rotatably set at the front end of the upper cover 102 of the base 1. The traction rope 404 passes around the steering wheel 8 to bend the rope body, and the winding motor 402 is set on one side of the pin piece 401.

[0052] A method for using a voice-controlled electric rotating structure of a child seat comprises the following steps:

[0053] Step (A): issuing a voice command: "rotate left / right" or "rotate left / right side", and the voice control module 7 controls the driving motor 301 and the winding motor 402 to operate according to the voice command;

[0054] Step (B): First, the winding motor 402 is controlled to operate. The output shaft of the winding motor 402 drives the winding disc 403 to rotate from the starting position to the end position, winding the traction rope 404 and pulling the pin 401 out of the gear slot 201 of the turntable 2.

[0055] Step (C): Next, the driving motor 301 is controlled to operate. The output shaft of the driving motor 301 drives the driving gear 302 to rotate, and drives the turntable 2 and the seat body to rotate left or right to a gear position through the transmission belt 303 and the driven gear 304.

[0056] Step (D): Finally, the winding motor 402 is controlled to operate again, driving the winding disc 403 to rotate from the end position to the initial position for reset, so that the traction rope 404 no longer pulls the pin 401, and the pin 401 is reinserted into the gear slot 201 by the restoring force of the spring 405;

[0057] Step (E): When further adjustment is required, repeat steps (A) to (D) to achieve voice-controlled rotation adjustment of the seat.
