[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0052] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7An automatic swinging device includes a base 1, a power source 2, and a transmission device 3 mounted on the base 1. A swing seat 4, capable of moving back and forth along the base 1, is mounted on the base 1. The power source 2 drives the transmission device 3, which in turn drives the swing seat 4 to move back and forth along the base 1. A fixing piece 5 for mounting the wheels of a stroller is installed on the swing seat 4. In use, the power source 2 activates the transmission device 3, which then drives the swing seat 4 to move back and forth along the base 1. The fixing piece 5 on the swing seat 4 secures the wheels of the stroller. This allows the stroller to swing automatically, avoiding the need for manual pushing by the user in existing technologies, greatly reducing workload and making it more practical.

[0053] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the power source 2 and the transmission device 3 are both located inside the base 1, and the base 1 has a mounting groove. The power source 2 and the transmission device 3 are installed in the mounting groove, and a swing seat 4 that can slide back and forth is installed on the opening of the mounting groove. This arrangement is more reasonable, which helps to avoid the power source 2 and the transmission device 3 being exposed. The overall design is also more novel and beautiful, reduces interference with the power source 2 and the transmission device 3, and improves their service life.

[0054] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the transmission device 3 includes an output gear 31 mounted on the power source 2 and a transmission gear 32 meshing with the output gear 31. A rocker arm 33 is mounted on the transmission gear 32 and is mounted on the swing seat 4. This arrangement is reasonable, facilitating the installation of the transmission device 3 and enabling the transmission to drive the swing seat 4 to move back and forth. Furthermore, it also includes a fixing frame 34 for fixing the output gear 31 while it is rotating. The fixing frame 34 is fixed to the base 1. This arrangement is reasonable and facilitates assembly. Further explanation is provided, as... Figure 1 , Figure 4 and Figure 8As shown, the power source 2 includes a battery pack 21 and a motor 22. The battery pack 21 provides electrical energy to the motor 22. An output gear 31 is provided on the output shaft of the motor 22. The output gear 31 is an output bevel gear, while the transmission gear 32 is a transmission bevel gear. The transmission bevel gear meshes with the output bevel gear for transmission. A rocker arm 33 is mounted on the transmission bevel gear. This facilitates the rotation of the rocker arm 33 by the motor 22. In this embodiment, the axis of the transmission bevel gear is arranged perpendicular to the axis of the output bevel gear. This arrangement facilitates the motion conversion of the motor 22. Finally, it should be noted that a fixing plate 35 is fixedly provided at the position where the rocker arm 33 passes through the fixing frame 34. This arrangement facilitates the rotation of the rocker arm 33. The base 1 is equipped with a charging port 11, an indicator light 12, and a power switch 13. Both the charging port 11 and the indicator light 12 are connected to a battery pack 21 (preferably a lithium battery in this embodiment), facilitating charging and providing illumination during charging for user awareness. The power switch 13 is connected to a motor 22, allowing control of the motor's on / off state. The base 1 also features ventilation holes to dissipate heat from the motor 22 and transmission device 3, extending the device's lifespan.

[0055] Among them, such as Figure 1 and Figure 4 As shown, the transmission bevel gear uses a rotating rod and upper and lower bearings set at the upper and lower ends of the rotating rod. In this embodiment, the upper and lower bearings are located at the upper and lower ends of the fixed frame 34, respectively. A bevel gear that meshes with the output gear 31 is provided on the rotating rod. This arrangement causes the output gear 31 to drive the bevel gear to rotate, and the bevel gear to drive the rotating rod to rotate. A rocker arm 33 is fixed on the upper end face of the rotating rod. The rotation of the rotating rod drives the rotation of the rocker arm 33.

[0056] Among them, such as Figure 1 , Figure 2 and Figure 8 As shown, the rocker arm 33 includes a connecting seat 331 fixed on the upper end face of the transmission gear 32 and a protruding rod 332 provided on the connecting seat 331. The connecting seat 331 and the protruding rod 332 are arranged perpendicularly. A swing seat 4 is provided on the protruding rod 332. This arrangement is beneficial for driving the swing seat 4 to move back and forth.

[0057] like Figure 10 and Figure 11 As shown, in this utility model, the rocker arm 33 is replaced by the intermediate gear 36, and a rack 37 is provided on one side of the base 1. The intermediate gear 36 meshes with the rack 37 for transmission. A swing seat 4 is fixed on the rack 37. It can be seen that there are many transmission methods to choose from.

[0058] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 1 , Figure 2 and Figure 4 As shown, the swing seat 4 includes a guide rail seat 41 mounted on the base 1 and a sliding seat 42 that moves back and forth along the guide rail seat 41. The sliding seat 42 has a limiting hole 43. The upper end face of the transmission device 3 is located in the limiting hole 43. A fixing seat 44 for fixing the wheels of the stroller is fixedly mounted on the sliding seat 42. The transmission device 3 drives the sliding seat 42 to slide back and forth along the guide rail seat 41, and the fixing seat 44 slides together with the sliding seat 42. This allows the wheels of the stroller on the fixing seat 44 and the stroller to swing back and forth. Further explanation: the limiting hole 43 is a strip-shaped hole. Specifically, the protrusion 332 in the transmission device 3 is located in the strip-shaped hole. This arrangement facilitates the rotation of the rocker arm 33, which drives the sliding seat 42 to slide back and forth along the guide rail seat 41. It also includes a limiting cover plate 45 disposed between the base 1 and the fixed seat 44. The limiting cover plate 45 has a limiting hole for the sliding seat 42 to slide. This arrangement is beneficial for the sealed installation of the fixed seat 44 on the one hand, and also for the sliding seat 42 to move back and forth on the other hand.

[0059] Among them, such as Figure 1 , Figure 2 and Figure 4 As shown, the guide rail seat 41 includes tracks that are distributed correspondingly to each other on the inner side wall of the base 1. The corresponding tracks are connected as a whole by connecting rods, and guide rail grooves are arranged along the length of the tracks. This arrangement is reasonable, simple in structure, and easy to implement. To further explain, the sliding seat 42 includes a fixed plate and fixed feet arranged on the fixed plate. The fixed feet are provided with protrusions for sliding back and forth on the guide rail grooves. In this embodiment, four fixed feet are used, and the fixed feet are arranged in pairs, which is more conducive to the smooth back and forth sliding of the sliding seat 42.

[0060] like Figure 10 and Figure 11 As shown, the rocker arm 33 is replaced by an intermediate gear 36, and a rack 37 is provided on one side of the base 1. The intermediate gear 36 meshes with the rack 37 for transmission. A swing seat 4 is fixed on the rack 37. It can be seen that there are many transmission methods and a large selection of options. The sliding seat 42 is fixed on the rack 37. The rotation of the intermediate gear 36 drives the rack 37 to move back and forth, thereby realizing the back and forth movement of the swing seat 4. In this embodiment, the guide rail seat 41 can be two parallel cylinders. The guide rail seat 41 is provided with a sliding sleeve for fitting on the cylinder. The cover plate 45 is provided with connecting seats (not shown in the figure) at both ends. The fixed seat 44 and the cover plate 45 can be fixedly connected by the connecting seats and screws or bolts, which is conducive to the back and forth movement.

[0061] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the fixing member 5 includes a groove 51 on the upper surface of the swing seat 4, and locking blocks 52 arranged on both sides of the groove 51 along its length. Locking sleeves 53 are engaged with the locking blocks 52, allowing the stroller wheels to be more securely placed in the groove 51. Further explanation: the locking sleeves 53 and the locking blocks 52 are engaged, which facilitates the removal and installation of the locking sleeves 53 and improves future maintenance. To further explain, as... Figure 9 As shown, the sleeve 53 includes a sleeve body and a slot 532 disposed on the lower end face of the sleeve body 531. The locking block 52 engages with the slot 532. The side wall thicknesses on both sides of the slot 532 are different (inconsistent), which is beneficial for clamping and fixing different sizes of stroller wheels. Since the sleeve 53 can be detached from the locking block 52, when the stroller wheels are thinner, the corresponding sleeves 53 need to be placed with the thicker side wall of the slot corresponding to each other. When the stroller wheels are thicker, the corresponding sleeves 53 need to be placed with the thinner side wall of the slot corresponding to each other. This is beneficial for meeting the requirements of different strollers and can be adjusted according to the size of the stroller wheels, which is more conducive to meeting usage needs.

[0062] Among them, such as Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the groove 51 is low in the middle and high on both sides, which is beneficial for placing the wheels on the stroller.

[0063] Example 6: This can be described based on Example 1, Example 2, Example 3, Example 4, or Example 5, such as... Figure 12 , Figure 13 and Figure 14 As shown, this utility model also provides a secondary booster that cooperates with the aforementioned automatic swing master 10, including a base 20 and a rolling wheel 201 disposed on the lower end face of the base 20. A mounting seat 202 is provided on the base 20, and a fixing groove 203 for fixing the baby stroller's rolling wheel is provided on the mounting seat 202. Further, the fixing groove 203 is lower in the middle and higher on both sides, which is beneficial for placing the baby stroller's rolling wheel. Even further, protrusions are provided on both sides of the fixing groove 203, and engaging limiting blocks 204 are provided on the protrusions. Since the limiting blocks 204 and the protrusions are engaged, it facilitates disassembly and subsequent maintenance. At the same time, the two limiting blocks 204 engaging with the corresponding protrusions helps to make the baby stroller's rolling wheel more stable. The lower surface of the limiting block 204 has a slot for engaging with the protrusion, such as... Figure 15As shown, the sidewalls on both sides of the slot have different thicknesses (inconsistent), which facilitates clamping of stroller wheels of varying thicknesses. When the stroller wheels are thinner, the corresponding limiting blocks 204 need to be positioned with the thicker sidewalls of the slot aligned. Conversely, when the stroller wheels are thicker, the corresponding limiting blocks 204 need to be positioned with the thinner sidewalls of the slot aligned. This adjustment is made according to the size of the stroller wheels, better meeting usage requirements. This invention uses the rolling wheels 201 to drive the base 20 and mounting base 202 to roll on the ground, thus enabling the stroller wheels to swing back and forth.

[0064] Example 7: Based on Example 6, this utility model also provides a stroller, including a stroller body and at least one automatic swing master and one auxiliary booster correspondingly disposed on the wheels of the stroller body. Since the stroller requires at least one automatic swing master and at least one of the aforementioned auxiliary boosters, the automatic swing master provides the power source, and the auxiliary booster provides the assist for back-and-forth swinging. Because the automatic swing master and auxiliary booster are at the same height, this helps ensure that the wheels on the stroller are on the same horizontal plane, thus making the stroller stable. For example, a stroller with four wheels can be configured as follows:

[0065] Four of the rollers are equipped with an automatic swing mechanism;

[0066] One of the rollers is equipped with an automatic swing master, while the other three rollers are equipped with auxiliary boosters;

[0067] Two of the rollers are equipped with automatic swing actuators, while the other two rollers are equipped with auxiliary actuators.

[0068] Three of the rollers are equipped with an automatic swing master, and one of the rollers is equipped with a secondary booster.

[0069] One of the front rollers (or rear rollers) is equipped with an automatic swing master, and the other is equipped with an auxiliary booster. Although the four rollers are not on the same horizontal plane, two of them are on the same horizontal plane, which can still achieve smooth back-and-forth swinging.

[0070] It is evident that this utility model is suitable for application on strollers, with a variety of application methods, providing users with a wide range of choices. It is more conducive to soothing babies to sleep, avoiding the time-consuming and laborious process of manually pushing strollers back and forth as in existing technologies. It greatly frees up hands, reduces the burden on social work, and has significant market value.

[0071] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology. The internal components of the motor, battery pack and switch all adopt conventional models in the existing technology, and their internal structure belongs to the existing technology structure. Workers can complete normal operation according to the existing technical manual. In addition, the circuit connection adopts conventional connection methods in the existing technology, and will not be described in detail here.
