The screw sleeve slides along the smooth rod, and the push rod changes shape, thereby providing a pushing force to the connecting plate. The connecting plate deflects around the axis of rotation and connects with the cradle until the cradle deflects to a suitable angle. Then, the servo drive drives the bracket to perform periodic reciprocating swings. The bracket connects with the cradle, thereby achieving auxiliary soothing of the baby. This ensures the normal operation of the rocking chair, while the cradle part can be adjusted in deflection angle according to usage needs, thereby improving the applicability of the electric rocking chair.

[0015] 2. In this application, during the periodic reciprocating motion of the cradle driven by the bracket, the sliding sleeve at the bottom of the bracket slides synchronously along the sliding rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An electric rocking chair includes a cradle 1, a base 2, a top compartment 3, and a servo drive integrated inside the top compartment 3. The output end of the servo drive is fixedly connected to a bracket 4. The top of the bracket 4 is rotatably connected to a connecting plate 7 via a rotating shaft. The top of the bracket 4 is integrated with a push assembly for providing traction force to the connecting plate 7. The top of the connecting plate 7 is fixedly connected to the bottom of the cradle 1.

[0025] By rotating the transmission rod 12, the outer wall of the transmission rod 12 provides traction force to the screw sleeve through screwing with the screw sleeve. The screw sleeve slides along the smooth rod 13, and the push frame 8 changes shape, thereby providing a pushing force to the connecting plate 7. The connecting plate 7 deflects around the rotating shaft and connects to the cradle 1. After the cradle 1 deflects to the appropriate angle, the servo drive drives the bracket 4 to perform periodic reciprocating swings. The bracket 4 connects to the cradle 1, thereby achieving auxiliary soothing of the baby. This ensures the normal operation of the rocking chair. At the same time, the deflection angle of the cradle 1 can be adjusted according to the usage requirements, thereby improving the applicability of the electric rocking chair.

[0026] Specifically, such as Figure 2 and Figure 4As shown, a sliding rod 5 is fixedly connected to the top of the base 2 via a bracket 6, and a sliding sleeve 9 is fixedly connected to the bottom of the bracket 4. The inner wall of the sliding sleeve 9 is slidably connected to the outer wall of the sliding rod 5. During the periodic reciprocating motion of the cradle 1 driven by the bracket 4, the sliding sleeve 9 at the bottom of the bracket 4 slides synchronously along the sliding rod 5. This improves the stability of the cradle 1's movement without affecting its regular motion, thereby further improving the stability of the electric rocking chair. A mounting plate 1 is fixedly connected to the outer wall of the sliding sleeve 9. The mounting plate 1 is fixedly connected to the bottom of the bracket 4 via a fixing rod 11. A mounting plate 2 is fixedly connected to the bottom of the bracket 6. The mounting plate 2 is fixedly connected to the top of the base 2 via a locking rod 10, thus ensuring the ease of disassembly and assembly of the sliding sleeve 9 and the sliding rod 5.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the bottom of the cradle 1 is fixedly connected to the connecting plate 7 by screws, thereby ensuring the ease of assembling and disassembling the cradle 1. The pushing component includes two sets of protrusions fixedly connected to the top of the bracket 4. A transmission rod 12 is connected between the two sets of protrusions. A threaded sleeve is screwed onto the outer wall of the transmission rod 12. A pusher 8 is hinged to the top of the threaded sleeve. The open end of the pusher 8 is hinged to the bottom of the connecting plate 7. A smooth rod 13 is fixedly connected between the two sets of protrusions. The outer wall of the smooth rod 13 is slidably connected to the inner wall of the threaded sleeve. The outer wall of the transmission rod 12 provides traction force to the threaded sleeve by screwing it onto the threaded sleeve. The threaded sleeve slides along the smooth rod 13, and the pusher 8 changes shape, thereby providing a pushing force to the connecting plate 7.

[0028] Working principle: By rotating the transmission rod 12, the outer wall of the transmission rod 12 provides traction force to the screw sleeve through screwing with the screw sleeve. The screw sleeve slides along the smooth rod 13, and the push frame 8 changes shape, thereby providing a pushing force to the connecting plate 7. The connecting plate 7 deflects around the axis of rotation and connects with the cradle 1. After the cradle 1 deflects to the appropriate angle, the servo drive drives the bracket 4 to perform periodic reciprocating swing. The bracket 4 connects with the cradle 1 to achieve auxiliary soothing of the baby. This ensures the normal operation of the rocking chair. At the same time, the deflection angle of the cradle 1 can be adjusted according to the usage requirements, thereby improving the applicability of the electric rocking chair. During the periodic reciprocating motion of the bracket 4 and the cradle 1, the sliding sleeve 9 at the bottom of the bracket 4 slides synchronously along the sliding rod 5. This does not affect the regular movement of the cradle 1 and improves the stability of the movement of the cradle 1, thereby further improving the stability of the electric rocking chair.
