Detailed Implementation Methods

[0031] The present invention will now be further described with reference to the accompanying drawings:

[0032] like Figures 1 to 8 As shown, a translational swinging device includes a base 1 and a swing seat 2 mounted on the base 1 for mounting a cradle. The base 1 has a guide device 9 for the swing seat 2 to slide back and forth. A drive device 4 is provided between the base 1 and the swing seat 2 to drive the swing seat 2 to slide back and forth. The base 1 also has a control device 5 to control the drive device 4 to drive the swing seat 2 back and forth. When the translational swinging device of this invention is installed on an electric rocking chair, the base 1 is connected to the chair frame, the cradle is mounted on the swing seat 2, and the control device 5 controls the drive device 4 to drive the swing seat 2 to reciprocate relative to the base 1, thereby causing the cradle to swing and realizing automatic rocking of the rocking chair. It is convenient and labor-saving to use, and the regular operation of the motor makes the rocking chair more comfortable for the baby.

[0033] Specifically, the drive device 4 includes a rack 41 mounted on the base 1 and extending horizontally, a drive motor 42 mounted on the swing seat 2, and a drive gear 43 mounted on the output shaft of the drive motor 42 and meshing with the rack 41 to drive the drive motor 42 to move along the rack 41, thereby causing the swing seat 2 to translate relative to the base 1. In this way, the drive motor 42 drives the drive gear 43 to rotate during operation, and the drive gear 43 meshes with the rack 41 to drive the drive motor 42 to move along the rack 41, thereby causing the swing seat 2 to slide and translate relative to the base 1.

[0034] Furthermore, the drive motor 42 is equipped with a positioning piece 6 that moves with the drive motor 42. The control device 5 includes two first sensors 51 that are spaced apart from each other on the base 1 along the moving direction of the drive motor 42 and can respectively sense the positioning piece 6 and send a reverse signal to the drive motor 42, causing the swing seat 2 to move in the opposite direction. The present invention sets the positions of the first sensors 51 on both sides, so that when the positioning piece 6 reaches either of the first sensors 51, the drive motor 42 reverses according to the signal given by the first sensor 51, causing the swing seat 2 to move in the opposite direction, thereby realizing reciprocating motion. Specifically, the left and right movement stroke of the swing seat 2 can be set as needed, which effectively protects the device and also facilitates programming control of the time of the swing seat under this stroke to control the swing degree level of the electric rocking chair.

[0035] Specifically, the first sensor 51 is a photoelectric sensor. The first sensor 51 has a first transmitting end 511 that can emit light signals and a first receiving end 512 that can receive light signals and form a signal loop with the first transmitting end 511, spaced apart from each other. When the positioning piece 6 extends between the first transmitting end 511 and the first receiving end 512, the signal loop of the first sensor 51 is interrupted, sending a reverse signal to the drive motor 42. In the initial state, the signal loop of the first sensor 51 is always on, in a normally open state. When the positioning piece 6 moves with the drive motor and extends between the first transmitting end 511 and the first receiving end 512, the signal loop of the first sensor 51 is interrupted, generating a reverse signal, which is fed back to the control board of the drive motor 42. The drive motor 42 reverses, and then drives the swing seat 2 to move in the opposite direction.

[0036] Furthermore, a second sensor 8 is provided on the base 1 between the two first sensors 51, which can sense the position of the positioning piece 6 and send an initial position signal to the drive motor 42. When the electric rocking chair is finished using and needs to be stopped, the second sensor 8 is activated, and the positioning piece 6 continues to move to the second sensor 8 with the drive motor 42. The second sensor 8 senses the position of the positioning piece and sends an initial position signal to the drive motor 42. After receiving the signal, the drive motor 42 stops, so that the rocking seat 2 returns to its original position.

[0037] Specifically, the second sensor 8 is a photoelectric sensor. The second sensor 8 is provided with a second transmitting end 81 that can emit light signals and a second receiving end 82 that can receive light signals and form a signal loop with the second transmitting end 81. The positioning piece 6 is provided with a first sensing part 61 and a second sensing part 62. A notch 63 for light signals to pass through is provided between the first sensing part 61 and the second sensing part 62. The first sensing part 61 or the second sensing part 62 extends into the space between the second transmitting end 81 and the second receiving end 82 to cut off the signal loop. When the second sensor 8 passes through the notch 63 and the signal loop is turned on again, the signal loop of the second sensor 8 is interrupted, thus giving the initial position signal to the drive motor 42. During the swinging and translating operation, the signal circuit of the second sensor 8 is always closed. When the device needs to be turned off, the second sensor 8 receives a signal from the control panel and turns on, and the signal circuit between the second transmitter 81 and the second receiver 82 is connected and is normally open. When the positioning piece 6 moves with the drive motor, the first sensing part 61 or the second sensing part 62 extends between the second transmitter 81 and the second receiver 82, causing the signal circuit of the first sensor 51 to be interrupted. The positioning piece 6 continues to move with the drive motor, causing the notch 63 to move between the second transmitter 81 and the second receiver 82. At this time, the signal circuit of the second sensor 8 is connected again, generating a stop signal, which is fed back to the control board of the drive motor 42. The drive motor 42 stops driving the drive gear 43, so that the drive motor 42 no longer drives the swing seat 2 to move, thereby resetting the swing seat 2 to the set origin.

[0038] like Figure 3 and Figure 4 As shown, the guiding device 9 includes guide sleeves 91 disposed on both sides of the rack 41 and fixed to the base 1, and guide rods 92 slidably mounted on the guide sleeves 91 and fixed to the swing seat 2. Specifically, two guide rods 92 are provided on the swing seat 2 at intervals, and four guide sleeves 91 are provided and fixed to the base 1 in pairs. Each guide rod 92 is fitted with two guide sleeves 91 at intervals. When the drive motor 42 drives the swing seat 2 to perform reciprocating translational motion, the guide rods 92 slide back and forth in the guide sleeves 91.

[0039] An electric rocking chair using the aforementioned translational swinging device includes a footrest 3 mounted on a base 1, a cradle frame 7 for mounting a cradle on a swinging seat 2, and a speaker 10 detachably mounted on the cradle frame 7 for independently playing audio. The electric rocking chair of this invention offers multiple functions, providing regular rocking for infants while simultaneously playing audio such as music or stories through the speaker, enhancing enjoyment. Furthermore, the speaker is detachable and can be used independently, making it convenient to use.

[0040] like Figure 6As shown, the cradle frame 7 is hinged to the rocking seat 2. The cradle frame 7 includes a cradle base 71 and a support rod 72 fixed at one end to the cradle base 71 for mounting the cradle. The front end face of the cradle base 71 has a mounting groove 711 for accommodating the speaker 10. The speaker is inserted and embedded in the mounting groove. When the two are in actual contact, corresponding magnetic devices can be provided on the back of the speaker and the inside of the mounting groove, making it less likely for the speaker to fall off during use. The front end face of the cradle base 71 also has a touch panel 30, which can realize functions such as controlling the switch of the electric rocking chair and setting the rocking level.

[0041] Specifically, the speaker 10 includes a housing 101, a speaker 102 disposed within the housing, a battery 103, and a Bluetooth module 104 for connecting to digital devices and receiving wireless audio data. A positioning slot 712 is provided within the mounting groove 711. A hollow protrusion 1011, which can be inserted into the positioning slot 712, is provided on the housing 101. The speaker 102 is disposed within the hollow protrusion 1011. The hollow protrusion, inserted into the positioning slot, increases the insertion surface area, making the connection more secure. In a practical implementation, a rubber ring can be fitted onto the outer surface of the hollow protrusion to increase the friction at the connection point, thus making the speaker installation more reliable.

[0042] like Figure 6 and Figure 7 As shown, the mounting slot 711 is provided with a first charging contact 20 for connecting to a power supply. The speaker 10 is provided with a second charging contact 105 that is electrically connected to the battery 103 and makes conductive contact with the first charging contact 20 when the speaker 10 is installed in the mounting slot 711. This invention, by providing a first charging contact in the mounting slot, facilitates charging of the speaker when it is inserted and installed in the mounting slot, thus improving user convenience and extending the speaker's lifespan.

[0043] In this invention, the support rod 72 includes a U-shaped main rod 721 and a U-shaped rotating rod 722. The ends of the main rod 721 and the rotating rod 722 are hinged to form a U-shaped frame. The main rod 721 is inserted into the cradle seat 71. When the button 73 is pressed, the rotating rod 722 is unlocked and can rotate and unfold or fold relative to the main rod 721.

[0044] Specifically, the cradle seat 71 is provided with an insertion slot 712 for the main rod 721 to be inserted. The insertion slot 712 is provided with a first hinge seat 713. One end of the main rod 721 inserted into the insertion slot 712 is provided with a second hinge seat 723. The swing seat 2 is provided with a hinge shaft 21 through which the first hinge seat 713 and the second hinge seat 723 are threaded. In this embodiment, two first hinge seats 713 are provided on the back of the cradle seat 71, spaced apart from each other. Similarly, two second hinge seats 723 are provided on the main rod 721, spaced apart from each other. When one end of the main rod 721 is inserted into the insertion slot 712, the two second hinge seats 723 are inserted between the two first hinge seats 713. The hinge joint of the swing seat 2 is inserted between the two second hinge seats 723. The hinge shaft 21 passes through the hinge joint of the swing seat 2, the second hinge seats 723, and the first hinge seats 713. In this way, the cradle frame 7 is hinged to the swing seat 2.

[0045] In this invention, the speaker 10 has a handle 106 on its end face for grasping and removing it from the mounting slot 711. The speaker 10 is a Bluetooth speaker, which receives wireless audio data from digital devices such as mobile phones and tablets via a Bluetooth module to play music or listen to voice messages, making it convenient to use and enhancing the user experience. In practical applications, other wireless transmission methods such as Wi-Fi can also be used. When the speaker 10 needs to be removed for individual use, the user can grasp the handle 106 to remove it from the rocking chair.
