[0033] Compared with traditional rocking beds, this device is compact and portable, does not take up too much space in the home, and is particularly suitable for small households, especially for families who need to move baby strollers frequently. The design of this device is simple, and there is no need to purchase the entire device or replace the base of the baby stroller, which reduces the cost of use. At the same time, it is also suitable for various models of baby strollers, increasing its versatility and practicality. Since the device is directly installed on the baby stroller, it avoids the potential safety hazards caused by an additional rocking bed.

[0034] In an embodiment provided in the present disclosure, the positioning member 4 is connected to the driver 1 through a snap-fit ​​structure, thereby allowing the user to quickly connect and disassemble the positioning member 4 and the driver 1, providing a fast, stable and safe connection method for the stroller auxiliary rocking device, while simplifying the user's operating process and improving the portability and adaptability of the product.

[0035] Specifically, the snap-fit ​​structure includes a clamping platform 71 and a groove formed on the positioning member 4; a clamping hook is provided at the end of the clamping platform 71 for engaging the groove; and the other end of the clamping platform 71 is rotatably connected to a mounting seat 72 on the outer casing of the driver 1 through a pin shaft; wherein, a spring 73 connected to the outer casing is also provided on the clamping platform 71.

[0036] The operation process of the buckle structure is as follows: press the card platform 71 to compress the spring 73, in which case the card platform 71 opens upward, and the card platform 71 and the groove are in a non-engaged state; when the shell and the positioning member 4 are matched, the card platform 71 can be released, and based on the restoring force of the spring 73, the card platform 71 engages with the groove, thereby fixing the shell and the positioning member 4. Press the card platform 71 again to achieve the engagement relationship between the card platform 71 and the groove, and the lock between the shell and the positioning member 4 can be released, so that the auxiliary rocking device of the baby stroller can be disassembled or replaced.

[0038] The buckle structure allows the positioning member 4 to be quickly adjusted or replaced in different scenarios, increasing the adaptability and flexibility of the device. Due to the compact design of the buckle structure, the occupied space is reduced, which is conducive to the portability and storage of the device. The buckle structure supports multiple reuses, improving the durability and economy of the device.

[0039] In this embodiment, the positioning member 4 includes a main body portion 401 for connecting to a base and a clamping portion 402 for connecting to a clamping platform. The main body portion 401 is provided with a boss, and the clamping portion 402 is provided with a groove matching the boss. The boss in the main body portion 401 is embedded in the groove to maintain the position of the main body portion 401 relative to the clamping portion 402.

[0040] Furthermore, in order to improve the reliability of the connection between the two, a fastener such as a screw is provided on the clamping part, so that it can be tightened against the main body by twisting, thereby ensuring the position of the main body relative to the clamping part, that is, improving the reliability of the connection between the two.

[0041] In the present disclosure, the positioning member 4 is provided with an arc groove adapted to the shell, so that the shell is partially embedded in the arc groove. This arrangement can increase the fitting area between the positioning member 4 and the shell, which is beneficial to reduce the vibration of the driver 1 during operation, and on the other hand, can enhance the positioning reliability of the driver 1, so that the auxiliary rocking device of the baby carriage can rock the wheels stably, thereby simulating the touch of a human hand rocking, and helping the user to coax the baby to sleep.

[0042] The design of the arc groove allows the shell part to be embedded in the positioning member 4 with a larger area, increasing the contact area between the two, helping to reduce the vibration of the driver 1 during operation and providing a more stable shaking effect. Therefore, through the close fit between the arc groove and the shell, the positioning reliability of the driver 1 is enhanced, ensuring the stability of the device when shaking the wheel, which can better simulate the touch of a human hand gently shaking, providing a softer and more natural shaking action, helping to soothe the baby and make it easier for him to fall asleep.

[0043] Furthermore, a flexible cushion can be provided in the arc groove, which can reduce vibration and improve stability, and also help reduce noise generated when the device is running, creating a quieter environment. At the same time, the design of the cushion can also reduce wear caused by vibration and instability, thereby improving the durability and service life of the device.

[0044] It should be noted that the base of the present disclosure can be a wall or a baby stroller body. For this, under the technical concept of the present disclosure, a positioning member 4 of at least one specification and model can be provided.

[0045] In one embodiment, see Figure 1 As shown, the base is a pillar of a baby stroller. In this case, the positioning member 4 is provided with an open slot 41 for clamping the pillar of the baby stroller. The open slot 41 allows the positioning member 4 to be easily clamped on the pillar of the baby stroller, providing a quick and easy fixing method. The positioning member 4 is also provided with a locking screw 6, which points radially toward the pillar. In this way, the locking screw 6 can be adjusted radially to adapt to pillars of different thicknesses, thereby increasing the versatility and applicability of the device. By tightening the locking screw 6, the stability and safety of the baby stroller auxiliary rocking device during use can be ensured.

[0046] The combination design of the opening slot 41 and the locking screw 6 enables the device to adapt to different models and designs of baby strollers. In addition, the use of the locking screw 6 to press against the column to fix the baby stroller can cause less damage to the surface of the baby stroller than direct fastening. The design of the locking screw 6 simplifies the installation process of the device, and the user can easily install and remove it.

[0047] Optionally, in Figure 1In the technical solution shown, a pressure pad is also provided on the locking screw 6. Based on the flexible deformation effect of the pressure pad, a buffering effect can be played, which can not only reduce the damage to the baby carriage, but also increase the friction force to ensure the reliability of the locking position.

[0048] In another embodiment, see Figures 2 to 4 As shown, the base is a wall. In this case, the positioning member 4 can be connected to the base by any suitable means such as gluing, clamping, screwing, etc. In this regard, those skilled in the art can flexibly configure the structure of the positioning member 4 based on the technical concept of the present disclosure.

[0049] It should be noted that in the present disclosure, the transmission methods include but are not limited to key connection, gear assembly connection, chain transmission connection, gear rack connection, etc. When the driver is connected to the connecting rod through gear rack transmission, it is necessary to adapt the structure of the connecting rod according to the power transmission principle, that is, the transmission wheel is equipped with a gear, and a rack is set on the connecting rod, thereby transmitting power to the connecting rod in this way.

[0050] In one embodiment, the transmission wheel is configured as a gear; the connecting rod is provided with a rack meshing with the gear; wherein one end of the connecting rod is slidably arranged through a sliding structure, and when the driver rotates, the gear drives the rack to move, so that the connecting rod pushes the wheel to shake. This can improve the stability of power transmission, thereby making the wheel shake smoothly.

[0051] In another embodiment, one end of the connecting rod 3 is eccentrically connected to the transmission wheel 2, and the other end is rotatably connected to the stopper 5; the stopper 5 is detachably connected to the wheel of the baby carriage; a latch is provided on the transmission wheel 2, wherein the latch is eccentrically arranged relative to the axis of the transmission wheel 2 and is rotatably connected to the connecting rod 3. The eccentric arrangement of the latch allows the latch to efficiently transmit power from the transmission wheel 2 to the connecting rod 3 when the transmission wheel 2 rotates, thereby driving the connecting rod 3 to generate reciprocating motion, and this motion can be transmitted to the wheel of the baby carriage to achieve a shaking effect.

[0052] By utilizing the eccentric wheel principle, complex motions are realized through a simple mechanical structure, reducing additional complex components. Due to the direct connection between the latch and the transmission wheel 2, energy loss during the transmission process is reduced, and the structure of the entire device is made more compact, which is convenient for installation and carrying.

[0053] Furthermore, an annular groove is provided on the housing of the driver 1, and a guide platform is provided on the side of the transmission wheel 2 facing the annular groove, and the guide platform is inserted into the annular groove. Based on the cooperation between the guide platform and the annular groove, when the driver 1 drives the transmission wheel 2 to rotate, the guide platform can move along the annular groove, which is beneficial to improve the coaxiality of the transmission wheel 2 relative to the output shaft, so that the transmission wheel 2 moves smoothly relative to the driver 1, and then indirectly acts on the baby carriage wheel, so that it can rock smoothly and softly, thereby simulating the rocking effect of a cradle, which helps to soothe the baby and make it fall asleep.

[0054] In one embodiment provided by the present disclosure, the auxiliary rocking device for a baby stroller further includes a tying piece, and the limiting piece 5 is provided with a strip groove 51 for passing the tying piece, and the strip groove 51 is arranged at intervals along the axial direction of the wheel. The tying piece is passed through the strip groove 51, so that the auxiliary rocking device for the baby stroller can be more firmly fixed to the baby stroller, reducing displacement or loosening during use. In addition, the strip groove 51 is arranged at intervals along the axial direction of the wheel, so that the tying piece can adapt to wheels of different sizes and shapes. In addition, the design of the strip groove 51 allows the user to adjust the position and tightness of the tying piece as needed to achieve the best fixing effect.

[0055] In the present disclosure, the binding member is configured as a Velcro, and the connection is achieved through the grinding hair and barbs on the Velcro. In other embodiments, it can be configured as a nylon belt, a hemp rope or any other suitable binding belt.

[0056] In one embodiment provided by the present disclosure, the bottom surface of the stopper 5 is formed into a curved surface adapted to the wheel. The contact area between the bottom surface of the curved surface and the wheel is larger, which helps to provide more stable support. By dispersing the contact points, the curved surface design helps to reduce the pressure on specific areas of the wheel and avoid deformation or damage to the wheel. At the same time, it can also better adapt to baby stroller wheels of different shapes and sizes, increasing the versatility of the device.

[0057] In order to ensure the rocking effect, a flexible pad is provided on the bottom. When the device is working, the flexible pad on the bottom can provide a certain cushion for the wheels, reduce vibration and noise, help achieve a more stable and natural rocking effect, and provide a comfortable coaxing experience for the baby.

[0058] In the present disclosure, the driver 1 is configured as a speed reducer. In other embodiments, the driver 1 can also be configured as other types of commercially available motors. In this regard, those skilled in the art can select different models according to usage requirements.

[0059] In the present disclosure, the baby stroller auxiliary rocking device also includes a timer and a controller, and the controller is communicatively connected to the driver 1 and the timer. The controller can automatically control the start and stop of the driver 1 to achieve precise control of the rocking action of the baby stroller. At the same time, the timer allows the user to set a specific time, and the baby stroller auxiliary rocking device will automatically stop working after the preset time. By controlling the working time through the timer, long-term ineffective operation can be avoided and energy can be saved. The coordinated use of the controller and the timer can also avoid safety problems that may be caused by forgetting to turn off the device.

[0060] Users can adjust the frequency, amplitude and time of shaking through the controller according to the baby's age and need for coaxing to sleep. When used, the controller provides a convenient operation interface, allowing users to easily set and adjust the working status of the coaxing device.

[0061] Furthermore, the controller can integrate intelligent algorithms to automatically adjust the rocking mode according to the baby's response to improve the efficiency of coaxing the baby to sleep, thereby providing a more humane and intelligent user experience to meet the needs of modern families.

[0062] In the present disclosure, the controller is configured as a single chip microcomputer.

[0063] Specifically, in the present invention, the controller may also be configured as a central processing unit (CPU). In other embodiments, the controller may also be configured as a digital signal processor (DSP), an application specific integrated circuit (ASIC), or a field programmable gate array (FPGA).

[0064] In the present disclosure, the controller is connected to the timer and the driver 1 through cables.
