Description

Technical Field

[0001] This utility model relates to the technical field of baby electric devices, and specifically to a baby electric device with an anti-jamming mechanism. Background Technology

[0002] Electric baby swings typically use a motor to drive the seat assembly in a reciprocating motion to achieve the rocking function of a swing. Specifically, the motor drives a transmission mechanism through forward and reverse motion, which in turn causes the swinging components (such as swing arms or linkages) connected to the seat assembly to swing periodically. However, the connection between the transmission mechanism and the swinging components is prone to jamming, thus requiring the design of an electric baby swing device with an anti-jamming mechanism.

[0003] In addition, existing baby electric devices only have a single swing bed mode or rocking chair mode, and users can only purchase a swing bed or rocking chair separately due to limited space in their home. Utility Model Content

[0004] This utility model proposes an electric baby device with an anti-jamming mechanism. During the operation of the device, the locking rod assembly of the transmission switching mechanism drives the swing bed connector to swing back and forth. Since the anti-jamming pin has a slight adjustment space in the anti-jamming slot, this design can effectively absorb the unavoidable errors during the assembly process, as well as the slight displacement caused by the swing during long-term use of the device.

[0005] An electric baby device with an anti-jamming mechanism designed for this purpose includes a swing joint for detachable connection with the seat assembly and a transmission switching mechanism for driving the swing joint to reciprocate.

[0006] The transmission switching mechanism includes a locking rod assembly connected to the swing bed connector. The connection between the locking rod assembly and the swing bed connector is provided with an anti-jamming pin and an anti-jamming strip groove that cooperates with the anti-jamming pin.

[0007] The locking rod assembly of the transmission switching mechanism drives the swing bed joint to swing back and forth.

[0008] The anti-jamming groove is provided on the swing bed connector and extends through the front and rear sides of the swing bed connector. The length direction of the anti-jamming groove extends along the swing direction of the swing bed connector.

[0015] The locking rod assembly is inserted into the locking disc along the swing bed transmission component. The locking rod assembly is locked to the swing bed transmission component and the locking disc. During the operation of the drive shaft, the swing bed joint is driven to swing back and forth in sequence through the locking disc, the swing bed transmission component and the locking rod assembly.

[0022] The locking rod assembly disengages downward from the locking disc, and the locking pin disengages from the sensing block, so that the sensing block can detect whether the locking rod assembly is inserted into the locking disc, thereby switching the operating mode of the drive assembly.

[0041] 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.

[0042] See Figures 1-6 An electric baby device with an anti-jamming mechanism includes a swing bed connector 2 for detachable connection with a seat assembly 1, and a transmission switching mechanism 3 for driving the swing bed connector 2 to reciprocate.

[0043] The transmission switching mechanism 3 includes a locking rod assembly 4 connected to the swing bed connector 2. The connection between the locking rod assembly 4 and the swing bed connector 2 is provided with an anti-jamming pin 5 and an anti-jamming strip groove 6 that cooperates with the anti-jamming pin 5.

[0044] The locking rod assembly 4 of the transmission switching mechanism 3 drives the swing bed connector 2 to swing back and forth. The anti-jamming pin 5 has a slight adjustment space in the anti-jamming strip groove 6 to absorb assembly errors or slight offsets during the swinging process, thereby preventing the locking rod assembly 4 and the swing bed connector 2 from jamming during the swinging process.

[0045] By designing a detachable connection between the swing bed connector 2 and the seat assembly 1, users can easily assemble and disassemble the device according to their actual needs, enhancing its flexibility and operability. The transmission switching mechanism 3 enables the device to perform transmission functions in different modes. Key innovations include the anti-jamming pin 5 and anti-jamming groove 6 between the locking rod assembly 4 and the swing bed connector 2. During operation, the locking rod assembly 4 of the transmission switching mechanism 3 drives the swing bed connector 2 to swing back and forth. Because the anti-jamming pin 5 has a slight adjustment range within the anti-jamming groove 6, this design effectively absorbs unavoidable errors during assembly and minor offsets caused by swinging during long-term use. In traditional baby electric devices, the connection between the transmission mechanism and the swinging component is prone to jamming due to these errors and offsets, leading to malfunctions or even damage. This technology, through the cooperation of the anti-jamming pin 5 and the anti-jamming groove 6, ensures that the locking rod assembly 4 and the swing bed connector 2 remain smooth during swinging, significantly reducing the probability of jamming and improving the stability and lifespan of the device.

[0046] The anti-jamming groove 6 is provided on the swing bed connector 2 and extends through the front and rear sides of the swing bed connector 2. The length direction of the anti-jamming groove 6 extends along the swing direction of the swing bed connector 2. The anti-jamming pin 5 is fitted into the anti-jamming groove 6 with a clearance fit, so that the locking rod assembly 4 and the swing bed connector 2 form a floating connection.

[0047] Compared to fixed connections, floating connections offer significant advantages. During equipment operation, the floating connection allows the anti-jamming pin 5 to move slightly within the anti-jamming groove 6. The anti-jamming groove 6 releases the radial constraint on the anti-jamming pin 5, greatly reducing the probability of jamming.

[0048] The locking rod assembly 4 includes a locking rod 7, which has connecting holes 8 extending through its front and rear sides. One end of the locking rod 7 with the connecting hole 8 is inserted into the swing bed connector 2. An anti-jamming pin 5 is inserted into the anti-jamming groove 6 and the connecting hole 8 to connect the locking rod 7 to the swing bed connector 2. This connection method is simple in structure and easy to assemble, reducing the difficulty of production and assembly, and is beneficial for improving production efficiency and reducing production costs. Simultaneously, by using the anti-jamming pin 5 to penetrate the anti-jamming groove 6 and the connecting hole 8, not only is a stable connection between the locking rod 7 and the swing bed connector 2 achieved, but the micro-adjustment space characteristic of the anti-jamming groove 6 is also fully utilized. During equipment operation, when the locking rod 7 drives the swing bed connector 2 to swing, the movement of the anti-jamming pin 5 within the anti-jamming groove 6 can promptly compensate for positional deviations in the connection area caused by manufacturing tolerances, material deformation, and other factors. This ensures the accuracy and stability of power transmission between the locking rod 7 and the swing bed connector 2, effectively preventing jamming caused by inaccurate connections. This makes the equipment operation more reliable, reduces the frequency of equipment maintenance and repair, and provides users with a better user experience.

[0049] The outer diameter of the connecting hole 8 is larger than the inner diameter of the anti-jamming pin 5, and the length of the anti-jamming groove 6 is larger than the outer diameter of the connecting hole 8. This dimensional design further optimizes the anti-jamming function. Because the outer diameter of the connecting hole 8 is larger than the inner diameter of the anti-jamming pin 5, the anti-jamming pin 5 has a certain amount of room to move within the connecting hole 8. When the locking rod 7 and the swing bed connector 2 are subjected to external force interference or slight deformation during the swinging process, the anti-jamming pin 5 can be flexibly adjusted within the connecting hole 8, thereby avoiding jamming caused by rigid connection.

[0050] The swing bed connector 2 is provided with a plug slot 9 for inserting the locking rod 7.

[0051] It also includes a drive assembly 10 that is selectively connected to the swing bed connector 2 via a transmission switching mechanism 3;

[0052] The drive assembly 10 includes a drive shaft 11, a locking disc 12 is provided on the drive shaft 11, a swing bed transmission component 13 is provided on the outside of the locking disc 12, and a locking rod assembly 4 is movably mounted on the swing bed transmission component 13.

[0053] The locking rod assembly 4 disengages from the locking disc 12 along the swing bed transmission component 13. The swing bed transmission component 13 is sleeved on the outside of the locking disc 12, and the swing bed transmission component 13 and the locking disc 12 rotate relative to each other. The drive shaft 11 of the drive assembly 10 does not act on the swing bed transmission component 13, so that the drive shaft 11 is disconnected from the locking rod assembly 4 and the swing bed connector 2.

[0054] In this embodiment, the swing bed transmission component 13 is provided with a circular annular groove 13.1 for mounting the locking disc 12. When the locking rod assembly 4 is not inserted into the locking disc 12, the locking disc 12 rotates in the circular annular groove 13.1 via the drive shaft 11, without driving the swing bed transmission component 13 to move; the locking disc 12 performs a separate circumferential rotational motion.

[0055] The locking disc 12 is provided with a non-circular shaft hole 12.1 for inserting the drive shaft 11.

[0056] The locking rod assembly 4 is inserted into the locking disc 12 along the swing bed transmission component 13. The locking rod assembly 4 is locked between the swing bed transmission component 13 and the locking disc 12. During the operation of the drive shaft 11, the swing bed joint 2 is driven to swing back and forth through the locking disc 12, the swing bed transmission component 13 and the locking rod assembly 4 in sequence.

[0057] By setting up the drive assembly 10 and cooperating with the transmission switching mechanism 3, flexible switching of the equipment's operating mode is achieved. The drive shaft 11 of the drive assembly 10 is equipped with components such as a locking disc 12 and a swing bed transmission component 13. The locking rod assembly 4 is movably mounted on the swing bed transmission component 13. When the locking rod assembly 4 disengages from the locking disc 12 along the swing bed transmission component 13, relative rotation occurs between the swing bed transmission component 13 and the locking disc 12. The drive shaft 11 does not act on the swing bed transmission component 13. At this time, the drive shaft 11 is disconnected from the locking rod assembly 4 and the swing bed connector 2, and the drive shaft 11 drives the locking disc 12 independently. When the locking rod assembly 4 is inserted into the locking disc 12 along the swing bed transmission component 13, the swing bed transmission component 13 and the locking disc 12 are locked together through the locking rod assembly 4. During operation, the drive shaft 11 sequentially drives the swing bed connector 2 to reciprocate through the locking disc 12, the swing bed transmission component 13, and the locking rod assembly 4, thus achieving swing bed mode operation. This transmission switching mechanism design allows the equipment to switch freely between different modes according to different user needs, meeting diverse user scenarios, improving the equipment's versatility and practicality, providing users with a richer user experience, and also expanding the product's market application scope.

[0058] The locking rod assembly 4 is provided with an adjusting pin 14 for adjusting the vertical position between the locking rod assembly 4 and the swing bed transmission component 13; the adjusting pin 14 is elastically movable within the locking rod assembly 4, and the swing bed transmission component 13 is provided with an adjusting hole 15 corresponding to the adjusting pin 14 for operating the elastic extension and retraction of the adjusting pin 14.

[0059] The locking rod assembly 4 and the swing bed transmission component 13 are provided with a travel limit hole 16 and a limit pin 17 that passes through the travel limit hole 16;

[0060] The locking rod assembly 4 is inserted upward into the locking disc 12, the limiting pin 17 moves upward into the travel limiting hole 16, and the adjusting pin 14 extends into the adjusting hole 15 so that the locking rod assembly 4 is kept in the position of being inserted upward into the locking disc 12; the adjusting pin 14 retracts into the adjusting hole 15, the locking rod assembly 4 disengages from the locking disc 12, and the limiting pin 17 moves downward and is limited within the travel limiting hole 16 so that the locking rod assembly 4 is kept in the position of being disengaged downward from the locking disc 12.

[0061] The adjusting pin 14 on the locking rod assembly 4, along with its cooperation with the adjusting hole 15, travel limit hole 16, and limit pin 17 on the swing bed transmission component 13, enables precise control and reliable locking of the vertical position between the locking rod assembly 4 and the swing bed transmission component 13. The adjusting pin 14 moves elastically within the locking rod assembly 4. When switching equipment operating modes, the adjusting pin 14 can be moved into or out of the adjusting hole 15, facilitating the vertical movement of the locking rod assembly 4 on the swing bed transmission component 13. When the locking rod assembly 4 is inserted upwards into the locking disc 12, the limit pin 17 moves upwards into the travel limit hole 16, and the adjusting pin 14 extends into the adjusting hole 15. This structural design effectively prevents the locking rod assembly 4 from accidentally disengaging from the locking disc 12 due to vibration, external forces, or other factors during equipment operation, ensuring the stability and reliability of the equipment in swing bed mode. When the adjusting pin 14 retracts into the adjusting hole 15, the locking rod assembly 4 disengages from the locking disc 12, and the limiting pin 17 moves downward and is limited within the travel limiting hole 16. This ensures that the locking rod assembly 4 remains stably in the disengaged position from the locking disc 12, providing a reliable guarantee for switching the equipment to other operating modes. This precise position control and locking structure improves the accuracy and reliability of equipment operating mode switching, reduces the risk of equipment failure due to improper mode switching, and further enhances the overall performance of the equipment and the user experience.

[0062] The locking rod assembly 4 is provided with a resiliently movable locking pin 18;

[0063] The locking disc 12 is provided with a plurality of circumferentially spaced locking holes 19, and the locking disc 12 is provided with a detection element 20, and the detection element 20 is provided with a plurality of circumferentially spaced sensing blocks 21; an anti-rotation component 22 is provided between the detection element 20 and the locking disc 12 to prevent the two from rotating relative to each other, so that the sensing blocks 21 are arranged in a one-to-one correspondence with the locking holes 19.

[0064] In this embodiment, the locking disc 12 is provided with an annular groove 12.2 for mounting the detection element 20. The anti-rotation component 22 includes a plurality of locking blocks 12.3 spaced apart in the annular groove 12.2 and locking grooves 20.1 on the detection element 20. The gap between two adjacent sensing blocks 21 forms the locking groove 20.1. When the sensing block 21 of the detection element 20 is inserted into the annular groove 12.2 of the locking disc 12, the locking block 12.3 is inserted into the locking groove 20.1 to prevent relative rotation between the detection element 20 and the locking disc 12.

[0065] In this embodiment, the inner wall of the annular groove 12.2 of the swing bed transmission component 13 is provided with an inner bottom hole 13.2 for connecting the locking hole 19 and the insertion point of the locking rod assembly 4.

[0066] The locking rod assembly 4 is inserted upward into the locking disc 12, and the locking pin 18 is inserted into the corresponding locking hole 19 and acts elastically on the sensing block 21.

[0067] The locking rod assembly 4 disengages downward from the locking disc 12, and the locking pin 18 disengages from the sensing block 21, so as to detect whether the locking rod assembly 4 is inserted into the locking disc 12 through the sensing block 21, thereby switching the operating mode of the drive assembly 10.

[0068] The locking pin 18, which moves elastically on the locking rod assembly 4, cooperates with the locking hole 19, the detection element 20, and the sensing block 21 on the locking disc 12 to achieve accurate detection and reliable locking of the locking rod assembly 4's insertion into the locking disc 12. When the locking rod assembly 4 is inserted upward into the locking disc 12, the locking pin 18 elastically acts on the sensing block 21 while being inserted into the corresponding locking hole 19. This dual locking and detection mechanism ensures a firm connection between the locking rod assembly 4 and the locking disc 12 through the cooperation of the locking pin 18 and the locking hole 19, preventing loosening or detachment during equipment operation and ensuring the stability and reliability of power transmission. On the other hand, by detecting the position of the locking pin 18 through the sensing block 21, it can accurately determine whether the locking rod assembly 4 has been successfully inserted into the locking disc 12, thus providing accurate signal feedback for switching the equipment's operating mode. When the locking rod assembly 4 is disengaged downward from the locking disc 12, the locking pin 18 disengages from the sensing block 21, and the equipment can adjust its operating mode in a timely manner based on the detected signal, avoiding equipment malfunctions or abnormal operations caused by misjudging the state of the locking rod assembly 4. This design improves the intelligence and reliability of the equipment, enhances its safety and stability, and provides users with a more intelligent and convenient user experience.

[0069] In this embodiment, the housing of the drive assembly 10 is provided with a circuit board and a conductive component fixed to the circuit board and electrically connected to the circuit board. One end of the conductive component acts elastically on the detection component 20, and the housing of the drive assembly 10 is provided with a clearance hole corresponding to one end of the conductive component.

[0070] The locking disc 12 is provided with a rocking chair connector 23 that is detachably connected to the seat assembly 1;

[0071] The seat assembly 1 is connected to the rocking chair connector 23, and the locking rod assembly 4 is disengaged from the locking disc 12, and the drive assembly 10 operates in rocking chair mode;

[0072] The seat assembly 1 is connected to the swing bed connector 2, and the locking rod assembly 4 is inserted into the locking disc 12, and the drive assembly 10 operates in swing bed mode;

[0073] The rocking chair connector 23 is detachably connected to the locking plate 12, or the rocking chair connector 23 and the locking plate 12 are integrally formed.

[0074] The rocking chair connector 23 on the locking plate 12 and its connection to the seat assembly 1 enable flexible switching between rocking chair mode and swing bed mode for the baby electric device. When the seat assembly 1 is connected to the rocking chair connector 23 and the locking rod assembly 4 is disengaged from the locking plate 12, the drive assembly 10 operates in rocking chair mode; when the seat assembly 1 is connected to the swing bed connector 2 and the locking rod assembly 4 is inserted into the locking plate 12, the drive assembly 10 operates in swing bed mode. This design effectively solves the problem of existing baby electric devices having limited functionality, forcing users to purchase either a swing bed or a rocking chair separately due to space constraints in their homes. Users can freely choose the operating mode of the device according to their actual needs and home space, without needing to purchase additional equipment, thus reducing operating costs and increasing the utilization rate of the device.

[0075] The locking rod assembly 4 includes a locking rod 7, a locking head 24 and an intermediate part 25. The intermediate part 25 is provided with a laterally elastic adjusting pin 14 and an adjusting spring 26.

[0076] A through hole 28 for inserting a connecting pin 27 is provided between the lock head 24 and the intermediate part 25.

[0077] The intermediate component 25 and the locking rod 7 are provided with a through hole 29 for telescopic adjustment pin 14;

[0078] The lock head 24 is provided with a locking pin 18 that can be elastically extended and retracted vertically and an elastic spring 30. One end of the elastic spring 30 abuts against the locking pin 18, and the other end of the elastic spring 30 abuts against the intermediate piece 25.

[0079] The lock head 24 is combined with the intermediate part 25 and then inserted into the lock rod 7. A pin hole 31 for inserting the limiting pin 17 is provided between the lock rod 7 and the intermediate part 25.

[0080] In this embodiment, the seat assembly 1 includes an annular connecting tube 1.1 hinged to the base 32. One end of the annular connecting tube 1.1 is provided with a pin 1.2. The rocking chair connector 23 is provided with a transition seat 33 rotatably connected to it. Both the swing bed connector 2 and the transition seat 33 are provided with a locking block 34 and a compression spring 35 that acts elastically on the locking block 34. The locking block 34 is provided with an annular locking hole, and the pin 1.2 is provided with a locking groove. The thickness of the locking groove is greater than the thickness of the annular locking hole. When the seat assembly 1 is assembled with the swing bed connector 2 or the rocking chair connector 23, the pin 1.2 is inserted into the annular locking hole of the locking block 34. The annular locking hole is engaged with the locking groove under the elastic action of the compression spring 35 to prevent the pin 1.2 from disengaging. When the pin 1.2 disengages, the locking block 34 moves elastically, and the annular locking hole disengages from the locking groove, thereby realizing a detachable mating connection between the seat assembly 1 and the swing bed connector 2 or the rocking chair connector 23.

[0081] In this embodiment, the rocking chair connector 23 is provided with a connecting shaft hole that is eccentrically arranged with the drive shaft 11, and the adapter 33 is provided with a connecting shaft that is inserted into the connecting shaft hole.

The adjusting pin 14, which is laterally elastically movable on the intermediate component 25, cooperates with the adjusting spring 26 to easily adjust the vertical position relationship between the locking rod assembly 4 and the swing bed transmission component 13, ensuring that the locking rod assembly 4 can accurately connect or disengage from the locking disc 12 in different operating modes. The locking head 24 and the intermediate component 25 are fixedly connected by connecting pin 27, and are equipped with elastically telescopic locking pin 18 and elastic spring 30, which improves the reliability and stability of the connection while achieving a locking connection with the locking disc 12 through the elastic structure. In addition, this combined structural design makes the functional division between each component clear, facilitates manufacturing and assembly, improves production efficiency, and reduces production costs.
