Description

Technical Field

[0001] This utility model relates to the technical field of baby electric devices, and specifically to a transmission switching mechanism for baby electric devices. Background Technology

[0002] With the continuous development of the infant and toddler product market, multifunctional integrated products are increasingly favored by consumers. Currently, electric baby devices are mainly divided into two types: rocking chair mode and swing bed mode. Traditional products have obvious functional limitations; single-function devices occupy a large space, and users need to purchase two separate devices when they need to use two functions simultaneously.

[0003] When a baby electric device needs to integrate rocking chair mode and swing bed mode into the same device, the drive component needs to switch the transmission path to achieve dual-mode drive of a single drive component.

[0004] Therefore, it is necessary to design a transmission switching mechanism for baby electric devices. Utility Model Content

[0005] This invention proposes a transmission switching mechanism for an electric baby device. Through the up-and-down movement of the locking rod assembly, selective switching of the transmission connection between the drive assembly and the swing bed transmission component is achieved. In rocking chair mode, the locking rod assembly disengages from the rocking chair transmission component, and the drive shaft of the drive assembly independently drives the rocking chair transmission component, ensuring the normal operation of the rocking chair function. In swing bed mode, the locking rod assembly inserts into the rocking chair transmission component along the swing bed transmission component, locking the rocking chair transmission component to the swing bed transmission component. The drive shaft can then drive the rocking chair transmission component, the swing bed transmission component, and the locking rod assembly to move synchronously, thereby realizing the swing bed function.

[0006] A transmission switching mechanism for an infant electric device designed for this purpose includes a rocking chair transmission component and a drive assembly. The drive assembly has a drive shaft that is connected to the rocking chair transmission component and also includes a swing bed transmission component. The rocking chair transmission component and the swing bed transmission component are connected to each other in a relative rotational manner in rocking chair mode. The swing bed transmission component has a locking rod assembly that moves up and down toward the rocking chair transmission component. The drive assembly selectively connects to the swing bed transmission component and switches the transmission output path through the movement of the locking rod assembly. In rocking chair mode, the locking rod assembly disengages from the rocking chair transmission component, and the drive shaft of the drive component does not act on the swing bed transmission component and drives the rocking chair transmission component to move independently. In swing bed mode, the locking rod assembly is inserted into the swing bed transmission component, and the drive shaft of the drive assembly drives the rocking chair transmission component, the swing bed transmission component, and the locking rod assembly to move synchronously.

[0007] The rocking chair transmission component is equipped with a sensing detection element; In rocking chair mode, the locking lever assembly is disengaged from the rocking chair transmission components and does not act on the sensing and detection components; In swing bed mode, the locking rod assembly is inserted into the swing bed transmission component and acts on the sensing and detection component to switch the operating mode of the drive component through the locking rod assembly and the sensing and detection component.

[0008] The rocking chair transmission component is provided with a locking disc, and the swing bed transmission component is provided with a mounting cavity for installing the locking disc. The rocking chair transmission component is rotatably connected to the swing bed transmission component through the locking disc. The drive shaft passes through the mounting cavity and is inserted into the locking disc, which has a non-circular shaft hole that mates with the drive shaft.

[0009] The locking disc is provided with a number of circumferentially spaced locking holes, and the locking rod assembly can be inserted into or disengaged from the locking holes by moving up and down. The swing bed transmission component is provided with a through hole that connects to the mounting cavity and engages with the locking hole.

[0010] The locking disc is equipped with a sensing detection element that cooperates with the locking rod assembly; The locking disc is provided with a mounting slot for installing the sensing detection element, and the mounting slot is provided with a number of circumferentially spaced locking ribs. The sensing and detection device is provided with a number of sensing blocks, each sensing block is set in correspondence with each locking hole, and a locking groove is provided between two adjacent sensing blocks; The sensing element is assembled with the locking disc, the sensing block is inserted into the mounting slot, and the locking rib is inserted into the corresponding locking slot to prevent relative rotation between the sensing element and the locking disc. The locking rod assembly is inserted into the locking hole and contacts the corresponding sensing block.

[0011] The locking rod assembly is equipped with a locking pin that moves up and down elastically. The locking pin of the locking rod assembly is inserted into the rocking chair transmission component, and the locking pin remains locked and inserted into the rocking chair transmission component under the action of elasticity.

[0012] The locking rod assembly is provided with a connecting pin that is laterally elastic and movable. The swing bed transmission component is provided with an opening for the connecting pin to elastically extend and retract. The vertical position of the locking rod assembly on the swing bed transmission component is adjusted by the elastic extension and retraction of the connecting pin in the opening.

[0013] The locking rod assembly is provided with a limiting pin, and the swing bed transmission component is provided with a travel limiting hole that cooperates with the limiting pin; the limiting pin moves up and down with the locking rod assembly and is limited in the travel limiting hole. When the locking rod assembly moves upward along the swing bed transmission component and inserts into the rocking chair transmission component, the connecting pin elastically extends out of the opening so that the locking rod assembly remains inserted upward into the rocking chair transmission component on the swing bed transmission component. When the connecting pin retracts into the opening, the locking rod assembly moves downward along the swing bed transmission component and disengages from the rocking chair transmission component, and the limiting pin is limited within the travel limiting hole, so that the locking rod assembly remains on the swing bed transmission component and disengaged from the rocking chair transmission component.

[0014] The locking rod assembly includes a lock head and a middle part, and the lock head is provided with a locking spring and a locking pin. The intermediate component is inserted into the lock head, and one end of the locking spring acts elastically on the lock head, while the other end of the locking spring acts elastically on the intermediate component. The lock head and the intermediate component are provided with a connecting hole and a transverse through-connecting hole to fix the lock head and the intermediate component together. The intermediate component is provided with a horizontally telescopic connecting pin and a telescopic spring. One end of the telescopic spring acts elastically on the connecting pin, and the other end of the telescopic spring acts elastically on the inside of the lock head.

[0015] The locking rod assembly also includes a hanging rod, with the lock head and intermediate component inserted into the hanging rod, and the lock head extending out of the hanging rod. Both the hanging rod and the intermediate component are provided with through holes for the elastic extension and retraction of the connecting pin; both the hanging rod and the intermediate component are provided with through holes for inserting a limiting pin.

[0016] The baby electric device also includes a seat assembly, and one end of the rocking chair transmission component is provided with a rocking chair adapter seat that is detachably connected to the seat assembly. A connecting part that is eccentrically set with respect to the drive shaft is provided between the rocking chair transmission component and the rocking chair adapter seat. In rocking chair mode, the seat assembly is fixed to the rocking chair adapter, and the drive shaft of the drive component drives the rocking chair adapter and the seat assembly to make eccentric circular motion through the rocking chair transmission component. The locking rod assembly includes a suspension rod, on which a swing bed adapter seat is provided for detachable connection with the seat assembly; In swing bed mode, the seat assembly detaches from the rocking chair adapter and is fixed to the swing bed adapter. The locking rod assembly is inserted into the rocking chair transmission component towards the swing bed transmission component. The drive shaft of the drive component drives the swing bed adapter and seat assembly to reciprocate through the rocking chair transmission component, the swing bed transmission component and the locking rod assembly.

[0017] The beneficial technical effects of this utility model are as follows: In contrast to the limitations and large space requirements of traditional electric baby devices that only offer a single rocking chair or swing bed mode, this invention innovatively incorporates a swing bed transmission mechanism and locking rod assembly. The up-and-down movement of the locking rod assembly allows for selective switching of the transmission connection between the drive assembly and the swing bed transmission mechanism. In rocking chair mode, the locking rod assembly disengages from the rocking chair transmission component, and the drive shaft of the drive assembly independently drives the rocking chair transmission component, ensuring the normal operation of the rocking chair function. In swing bed mode, the locking rod assembly inserts into the rocking chair transmission component along the swing bed transmission component, locking the two components together. The drive shaft then drives the rocking chair transmission component, swing bed transmission component, and locking rod assembly to move synchronously, thus realizing the swing bed function—specifically, a swinging motion. The rocking chair transmission component, swing bed transmission component, and locking rod assembly reciprocate in both forward and reverse rotations of the drive shaft. This can be understood as the drive shaft rotating forward to a corresponding position angle and then rotating in the opposite direction. This technical solution primarily achieves the switching of transmission paths. This design eliminates the need for users to purchase two separate sets of equipment, greatly saving space while meeting users' needs for different modes. It improves the multi-functional integration of baby electric devices, providing users with a more convenient and efficient user experience and enhancing the product's competitiveness in the market.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0024] See Figures 1-5 A transmission switching mechanism for an infant electric device, the infant electric device including a rocking chair transmission component 1 and a drive assembly 2, the drive assembly 2 having a drive shaft 3 that is transmissionally connected to the rocking chair transmission component 1, and also including a swing bed transmission component 4, the rocking chair transmission component 1 and the swing bed transmission component 4 being relatively rotatably connected in rocking chair mode, the swing bed transmission component 4 having a locking rod assembly 5 that moves up and down toward the rocking chair transmission component 1, the drive assembly 2 selectively being transmissionally connected to the swing bed transmission component 4 and switching the transmission output path through the movement of the locking rod assembly 5; In rocking chair mode, locking rod assembly 5 disengages from rocking chair transmission component 1, and drive shaft 3 of drive assembly 2 does not act on swing bed transmission component 4 and drives rocking chair transmission component 1 to move independently. In the swing bed mode, the locking rod assembly 5 is inserted into the rocking chair transmission component 1 via the swing bed transmission component 4, and the drive shaft 3 of the drive assembly 2 drives the rocking chair transmission component 1, the swing bed transmission component 4, and the locking rod assembly 5 to move synchronously.

[0025] In response to the limitations of traditional electric baby devices, which only offer a single rocking chair or swing bed mode, resulting in functional constraints and large space requirements, this invention innovatively introduces a swing bed transmission component 4 and a locking rod assembly 5. The up-and-down movement of the locking rod assembly 5 enables selective switching of the transmission connection between the drive component 2 and the swing bed transmission component 4. In rocking chair mode, the locking rod assembly 5 disengages from the rocking chair transmission component 1, and the drive shaft 3 of the drive assembly 2 independently drives the rocking chair transmission component 1, ensuring the normal operation of the rocking chair function. In swing bed mode, the locking rod assembly 5 inserts into the rocking chair transmission component 1 along the swing bed transmission component 4, locking the rocking chair transmission component 1 and the swing bed transmission component 4 together. The drive shaft 3 can then drive the rocking chair transmission component 1, the swing bed transmission component 4, and the locking rod assembly 5 to move synchronously, thus realizing the swing bed function, specifically, swinging. The rocking chair transmission component 1, the swing bed transmission component 4, and the locking rod assembly 5 reciprocate in both forward and reverse directions with the drive shaft 3. This can be understood as the drive shaft 3 rotating forward to a corresponding position angle and then rotating in the opposite direction. This technical solution mainly achieves the switching of the transmission path, so the program control outside this technical solution will not be detailed here. This design eliminates the need for users to purchase two separate devices, greatly saving space while meeting users' needs for different modes. It improves the multi-functional integration of the baby electric device, bringing users a more convenient and efficient user experience and enhancing the product's competitiveness in the market.

[0026] The rocking chair transmission component 1 is equipped with a sensing detection component 7; In this embodiment, the sensing element 7 is a circuit board that works with the host computer. The driving component 2 is mounted on the host computer, which has a control box for mounting the circuit board. The control box has a clearance hole, and the circuit board has a conductive component that is electrically connected to it. One end of the conductive component passes through the clearance hole and contacts the sensing element 7. When the locking rod component 5 contacts the sensing element 7, the sensing element 7 outputs an electrical signal to the control chip on the circuit board through the conductive component. The conductive component is kept in contact with the sensing element 7 by a spring.

[0027] In rocking chair mode, the locking rod assembly 5 is disengaged from the rocking chair transmission component 1 and does not act on the sensing and detection component 7; In swing bed mode, the locking rod assembly 5 is inserted into the rocking chair transmission component 1 via the swing bed transmission component 4 and acts on the sensing and detection component 7, so as to switch the operating mode of the drive component 2 through the locking rod assembly 5 and the sensing and detection component 7.

[0028] A sensor 7 is installed on the rocking chair transmission component 1. In rocking chair mode, the locking rod assembly 5 disengages from the rocking chair transmission component 1 and does not act on the sensor 7. After the baby electric device is started, it can detect that the baby device is in rocking chair mode, so the drive shaft 3 will not run in either direction. When switching to swing bed mode, the locking rod assembly 5 inserts into the rocking chair transmission component 1 and acts on the sensor 7. The interaction between the two switches the operating mode of the drive component 2. This design allows the device to automatically recognize the current mode, eliminating the need for the user to manually select the mode on the control interface. On the one hand, it avoids abnormal device operation caused by user misoperation, improving the safety and stability of the device. On the other hand, it realizes intelligent switching of the operating mode of the drive component 2, making the operation of the device more convenient and user-friendly, further enhancing the user experience and technological feel of the product, and meeting the needs of modern consumers for intelligent products.

[0029] The rocking chair transmission component 1 is provided with a locking disc 8, and the swing bed transmission component 4 is provided with a mounting cavity 9 for installing the locking disc 8. The rocking chair transmission component 1 is rotatably connected to the swing bed transmission component 4 through the locking disc 8. The drive shaft 3 passes through the mounting cavity 9 and is inserted into the locking disc 8, which has a non-circular shaft hole 8.1 that mates with the drive shaft 3.

[0030] A locking disc 8 is provided on the rocking chair transmission component 1, and a mounting cavity 9 is provided on the swing bed transmission component 4, enabling the rocking chair transmission component 1 and the swing bed transmission component 4 to achieve a rotatable connection. When the locking rod assembly 5 does not lock the rocking chair transmission component 1 and the swing bed transmission component 4, the rocking chair transmission component 1 and the swing bed transmission component 4 rotate relative to each other, and the drive shaft 3 can only drive the rocking chair transmission component 1 to move independently, providing a structural basis for switching between the two modes. The drive shaft 3 passes through the mounting cavity 9 and is inserted into the locking disc 8, and the locking disc 8 is provided with a non-circular shaft hole 8.1 that mates with the drive shaft 3, ensuring stable transmission between the drive shaft 3 and the locking disc 8. At the same time, the locking hole 10 on the locking disc 8 mates with the locking rod assembly 5, and the through hole 4.1 on the swing bed transmission component 4 corresponds to the locking hole 10, allowing the locking rod assembly 5 to be inserted into or disengaged from the locking hole 10 by moving up and down, thereby realizing the switching of the transmission connection between the drive assembly 2 and the swing bed transmission component 4. This structural design not only ensures the flexibility of relative rotation between the rocking chair transmission component 1 and the swing bed transmission component 4, but also ensures the reliability and stability of the transmission connection when switching modes, making the entire transmission switching process smoother and more precise, and effectively improving the working efficiency and service life of the equipment.

[0031] The locking disc 8 is provided with a plurality of circumferentially spaced locking holes 10, and the locking rod assembly 5 is inserted into or disengaged from the locking holes 10 by moving up and down. The transmission component 4 of the swing bed is provided with a through hole 4.1 that connects to the mounting cavity 9 and is engaged with the locking hole 10.

[0032] The locking disc 8 is equipped with a sensing detection element 7 that cooperates with the locking rod assembly 5; The locking disc 8 is provided with a mounting groove 11 for mounting the sensing detection element 7, and the mounting groove 11 is provided with a plurality of circumferentially spaced locking ribs 12. The sensing detection element 7 is provided with a plurality of sensing blocks 13, each sensing block 13 being configured in a one-to-one correspondence with each locking hole 10, and a slot 14 being provided between two adjacent sensing blocks 13. The sensing element 7 is assembled with the locking disk 8, the sensing block 13 is inserted into the mounting groove 11, and the locking rib 12 is inserted into the corresponding locking groove 14 to prevent relative rotation between the sensing element 7 and the locking disk 8. The locking rod assembly 5 is inserted into the locking hole 10 and contacts the corresponding sensing block 13.

[0033] Furthermore, a sensing element 7 that cooperates with the locking rod assembly 5 is set on the locking disc 8. Through the mutual cooperation of the mounting groove 11, the locking rib 12, the sensing block 13, and the locking groove 14, relative rotation between the sensing element 7 and the locking disc 8 is prevented, ensuring the accuracy of the sensing detection. When the locking rod assembly 5 is inserted into the locking hole 10 and contacts the corresponding sensing block 13, it can accurately feed back the current mode status to the drive assembly 2, thereby achieving precise switching of the drive assembly 2's operating mode. This design not only enhances the device's detection accuracy for mode switching.

[0034] The locking rod assembly 5 is provided with a locking pin 15 that moves up and down elastically. The locking pin 15 of the locking rod assembly 5 is inserted into the rocking chair transmission component 1, and the locking pin 15 is kept locked and inserted into the rocking chair transmission component 1 under the action of elasticity.

[0035] The locking rod assembly 5 is equipped with a locking pin 15 that moves up and down elastically. When the locking pin 15 of the locking rod assembly 5 is inserted into the rocking chair transmission component 1, it can maintain the locked insertion state under the action of elasticity. In the swing bed mode, this design can ensure that the connection between the locking rod assembly 5 and the rocking chair transmission component 1 is stable and reliable. Even if the equipment is subjected to certain vibrations or external forces during operation, the locking pin 15 will not easily disengage from the rocking chair transmission component 1, ensuring the synchronous movement between the drive assembly 2, the rocking chair transmission component 1, the swing bed transmission component 4, and the locking rod assembly 5, so that the swing bed function can operate stably.

[0036] The locking rod assembly 5 is provided with a connecting pin 16 that is laterally elastically movable, and the swing bed transmission component 4 is provided with an opening 17 for the connecting pin 16 to elastically extend and retract. The vertical position of the locking rod assembly 5 on the swing bed transmission component 4 is adjusted by the elastic extension and retraction of the connecting pin 16 on the opening 17.

[0037] The locking rod assembly 5 is equipped with a laterally elastic connecting pin 16, and the swing bed transmission component 4 is equipped with an opening 17 for the elastic extension and retraction of the connecting pin 16. Through the elastic extension and retraction of the connecting pin 16 in the opening 17, the vertical position of the locking rod assembly 5 on the swing bed transmission component 4 can be adjusted. This design provides a more flexible adjustment method for the vertical movement of the locking rod assembly 5, enabling it to better adapt to different working states and mode switching requirements. When switching to the swing bed mode, the connecting pin 16 ensures that the locking rod assembly 5 is accurately inserted into the rocking chair transmission component 1, achieving a reliable transmission connection; while when switching back to the rocking chair mode, the locking rod assembly 5 can be easily disengaged from the rocking chair transmission component 1.

[0038] Specifically, when the baby electric device is in rocking chair mode, the locking rod assembly 5 is in its lowest position and not inserted into the rocking chair transmission component 1. When switching to swing bed mode, the user applies upward pressure on the locking rod assembly 5, causing it to insert upward into the rocking chair transmission component 1 until the connecting pin 16 locks onto the opening 17. When switching from swing bed mode to rocking chair mode, the user presses the connecting pin 16, causing it to retract into the opening 17, and then applies downward pressure on the locking rod assembly 5, causing it to disengage downward from the rocking chair transmission component 1.

[0039] The locking rod assembly 5 is provided with a limiting pin 19, and the swing bed transmission component 4 is provided with a travel limiting hole 18 that cooperates with the limiting pin 19; the limiting pin 19 moves up and down with the locking rod assembly 5 and is limited in the travel limiting hole 18. When the locking rod assembly 5 moves upward along the swing bed transmission 4 and inserts into the rocking chair transmission 1, the connecting pin 16 extends elastically out of the opening 17 so that the locking rod assembly 5 remains inserted upward into the rocking chair transmission 1 on the swing bed transmission 4. When the connecting pin 16 retracts into the opening 17, the locking rod assembly 5 moves downward along the swing bed transmission 4 and disengages from the rocking chair transmission 1, and the limiting pin 19 is limited within the travel limiting hole 18, so that the locking rod assembly 5 remains on the swing bed transmission 4 disengaged from the rocking chair transmission 1.

[0040] By providing a limiting pin 19 on the locking rod assembly 5 and a travel limiting hole 18 that cooperates with the limiting pin 19 on the millimeter bed transmission component 4, precise limiting of the up and down movement of the locking rod assembly 5 is achieved. When the locking rod assembly 5 moves upward and inserts into the rocking chair transmission component 1, the connecting pin 16 elastically extends out of the opening 17, keeping the locking rod assembly 5 in an upward inserted state and ensuring the stability of the transmission connection in the swing bed mode. When the limiting pin 19 retracts into the opening 17, the locking rod assembly 5 can move downward and disengage from the rocking chair transmission component 1, and is limited by the limiting pin 19 within the travel limiting hole 18. In this way, the limiting pin 19 and the travel limiting hole 18 cooperate to prevent relative rotation of the locking rod assembly 5 and the swing bed transmission component 4 when they are inserted. The lower position of the travel limiting hole 18 ensures that the locking rod assembly 5 can be disengaged from the swing bed transmission component 4 without disassembly. This limiting structure design effectively prevents excessive displacement or misalignment of the locking rod assembly 5 during the movement, further improving the accuracy and reliability of mode switching, while also enhancing the safety of equipment operation and avoiding equipment failure or safety hazards that may be caused by abnormal movement of the locking rod assembly 5.

[0041] The locking rod assembly 5 includes a lock head 20 and an intermediate part 21. The lock head 20 is provided with a locking spring 22 and a locking pin 15. The intermediate component 21 is inserted into the lock head 20, and one end of the locking spring 22 acts elastically on the lock head 20, while the other end of the locking spring 22 acts elastically on the intermediate component 21. The lock head 20 and the intermediate part 21 are provided with a connecting hole 23 and a transverse through connecting hole for fixing the lock head 20 and the intermediate part 21 with a transverse pin 24. The intermediate component 21 is provided with a horizontally telescopic connecting pin 16 and a telescopic spring 25. One end of the telescopic spring 25 acts elastically on the connecting pin 16, and the other end of the telescopic spring 25 acts elastically on the inner side of the lock head 20.

[0042] This design details the internal structure of the locking rod assembly 5, including components such as the lock head 20, intermediate part 21, locking spring 22, locking pin 15, connecting hole 23, transverse pin 24, connecting pin 16, and telescopic spring 25. The elastic action of the locking spring 22 and telescopic spring 25 allows the locking pin 15 and connecting pin 16 to move elastically, ensuring the flexibility and stability of the locking rod assembly 5 when engaged with the rocking chair transmission component 1 and the swing bed transmission component 4. The connecting hole 23 and transverse pin 24 ensure a fixed connection between the lock head 20 and the intermediate part 21, forming a stable structure for the entire locking rod assembly 5. This detailed internal structure design not only ensures the strength and reliability of the locking rod assembly 5 itself but also enables it to work more accurately and efficiently when performing mode switching functions, effectively improving the transmission performance and service life of the equipment, while also facilitating installation, maintenance, and repair.

[0043] In this embodiment, the lock head 20 has an assembly cavity for installing the locking pin 15, the locking spring 22, and the intermediate component 21. The locking pin 15 has a boss, and the top of the lock head 20 has an open slot. The inner diameter of the open slot is smaller than the outer diameter of the boss, and the outer diameter of the boss is smaller than the inner diameter of the assembly cavity. This ensures that the locking pin 15 is not easily dislodged from the lock head 20 when inserted from bottom to top. Then, the locking spring 22 and the intermediate component 21 are assembled. Next, the transverse pin 24 is inserted into the connecting hole 23 between the lock head 20 and the intermediate component 21, fixing the lock head 20 and the intermediate component 21 together. Before assembling the lock head 20 and the intermediate component 21, the connecting pin 16 and the telescopic spring 25 are installed on the intermediate component 21. The connecting pin 16 has a limiting boss, and the intermediate component 21 has a limiting cavity communicating with the through hole 27. The connecting pin 16 is inserted laterally into the limiting cavity, and the limiting boss is limited within the limiting cavity. Then, the telescopic spring 25 is installed. The outer diameter of the limiting boss is larger than the inner diameter of the through hole 27.

[0044] The locking rod assembly 5 also includes a hanging rod 26, with the locking head 20 and the intermediate part 21 both inserted into the hanging rod 26, and the locking head 20 extending out of the hanging rod 26. The hanging rod 26 and the intermediate part 21 are both provided with through holes 27 for the elastic extension and retraction of the connecting pin 16; the hanging rod 26 and the intermediate part 21 are both provided with through holes 28 for inserting the limiting pin 19.

[0045] The structure of the locking rod assembly 5 was further improved by introducing a hanger rod 26, and its cooperation with the lock head 20 and intermediate component 21 was explained. Both the lock head 20 and the intermediate component 21 are inserted into the hanger rod 26, with the lock head 20 extending beyond the hanger rod 26. The through holes 27 and 28 provided in the hanger rod 26 and intermediate component 21 provide movement space for the connecting pin 16 and the limiting pin 19, respectively, ensuring that the connecting pin 16 and the limiting pin 19 can extend and retract normally. This makes the up-and-down movement of the locking rod assembly 5 on the swing bed transmission component 4 and the connection and switching with the rocking chair transmission component 1 smoother. The addition of the hanger rod 26 not only enhances the overall structural strength of the locking rod assembly 5 but also makes its installation in the equipment more convenient and stable, further improving the structural stability and reliability of the equipment. It also provides a better solution for the overall layout and space utilization of the equipment.

[0046] In this embodiment, the suspension rod 26 is first inserted into the swing bed transmission component 4, and then the limiting pin 19 is inserted between the suspension rod 26 and the swing bed transmission component 4.

[0047] The electric baby device also includes a seat assembly 29, and a rocking chair transmission component 1 is provided at one end with a rocking chair adapter 30 that is detachably connected to the seat assembly 29. A connecting part 31 that is eccentrically arranged with the drive shaft 3 is provided between the rocking chair transmission component 1 and the rocking chair adapter 30. In rocking chair mode, the seat assembly 29 is fixed to the rocking chair adapter 30, and the drive shaft 3 of the drive assembly 2 drives the rocking chair adapter 30 and the seat assembly 29 to make eccentric circular motion through the rocking chair transmission component 1. Locking rod assembly 5 includes a hanging rod 26, on which a swing bed adapter 32 is provided for detachable connection with the seat assembly 29; In swing bed mode, seat assembly 29 detaches from rocking chair adapter 30 and is fixed to swing bed adapter 32. Locking rod assembly 5 is inserted into rocking chair transmission 1 towards swing bed transmission 4. Drive shaft 3 of drive assembly 2 drives swing bed adapter 32 and seat assembly 29 to reciprocate through rocking chair transmission 1, swing bed transmission 4 and locking rod assembly 5.

[0048] The design incorporates a seat assembly 29, a rocking chair adapter 30, and a swing bed adapter 32, enabling different installation methods for the seat assembly 29 in rocking chair and swing bed modes. In rocking chair mode, the seat assembly 29 is fixed to the rocking chair adapter 30. The drive shaft 3 of the drive assembly 2 drives the rocking chair adapter 30 and the seat assembly 29 to perform eccentric circular motion via the rocking chair transmission component 1, achieving the rocking chair function. In swing bed mode, the seat assembly 29 detaches from the rocking chair adapter 30 and is fixed to the swing bed adapter 32. The locking rod assembly 5 is inserted into the rocking chair transmission component 1.
