[0035] Child car seats, as essential tools for ensuring children's safe sitting, assisting with meals, education, or daily rest, are widely used. Current child car seat designs primarily focus on basic static posture support. These seats typically employ a fixed structure, meaning the seat and support frame are rigidly connected, forming an immovable unit. However, this fixed design often results in limited functionality and practicality, failing to adequately meet children's diverse needs in different scenarios (such as soothing, lulling to sleep, and interactive play). This often necessitates the purchase of additional tables and chairs with different functions to accommodate various needs, increasing costs and inconvenience. To address these issues, this utility model proposes a child car seat 100.

[0036] Please see Figures 1 to 3 In one embodiment of this utility model, the child seat 100 includes a support base 10 and a swing assembly 20. The swing assembly 20 includes a swing rod 35 and a seat 50. One end of the swing rod 35 is rotatable relative to the support base 10, and the seat 50 is connected to the swing rod 35. The child seat 100 has a fixed state and a swinging state. When the child seat 100 is in the fixed state, the swing rod 35 is fixed relative to the support base 10. When the child seat 100 is in the swinging state, the swing rod 35 is rotatable relative to the support base 10. When the swing rod 35 rotates, it drives the seat 50 to swing, and the seat 50 remains horizontal when swinging.

[0037] In this application, the support base 10 can be constructed by two uprights 11 to form the main support frame of the seat. The uprights 11 can be formed by bending and welding metal pipes to form a U-shaped structure, or they can be set up with a frame structure similar to "A". This application does not limit the structural form of the uprights 11.

[0038] The seat 50 can form a space for a child to sit and lean against. The swing arm 35 can be a steel rod with a hinge hole. One end of the swing arm 35 can be connected to the support seat 10 through a pin to form a rotating pair, so that the seat 50 and the swing arm 35 are connected. When the swing arm 35 can rotate relative to the support seat 10, it can be used as the rotating arm of the seat 50, so that the seat 50 can swing relative to the support seat 10, enriching the functionality of the child seat 100.

[0039] The seat 50 and the swing arm 35 are rotatably connected. A correction module can be installed in the seat 50. This module can identify the posture of the seat 50 during swinging using a gyroscope. When the seat 50 tilts during swinging, the correction module can be triggered to adjust the connection between the seat 50 and the swing arm 35, adjusting the tilt angle of the seat 50 so that the seat 50 remains horizontal during swinging. Alternatively, the swing arm 35 can have at least two rods rotating on the support base 10. By adjusting the connection positions or lengths of multiple rods on the support base 10, the connection positions of multiple rods to the seat 50 can be kept in a straight line during rotation. This, through the combined action of multiple rods, can constrain the swinging posture of the seat 50, ensuring that the seat 50 remains horizontal during swinging. Of course, the counterweight on the seat 50 can also be adjusted to keep the seat 50 horizontal during swinging. This application does not limit the method of achieving horizontality of the seat 50 during swinging. The way the seat 50 swings back and forth on a horizontal plane during the swinging motion helps prevent children from tipping over and falling off when the child seat 100 is used as a rocking chair, effectively improving the safety performance, practicality, and structural reliability of the child seat 100.

[0040] Specifically, the support base 10 can be provided with locking structures such as buckles, latches, and bolts that cooperate with each other between the swing arm 35 of the swing assembly 20 and / or the seat 50, so that the support base 10 and the swing assembly 20 can be locked or unlocked. Thus, when the support base 10 and the swing assembly 20 are locked together, the seat 50 can be fixed relative to the support base 10, so that the child seat 100 can be in a fixed seat position, making it convenient to use the child seat 100 as a dining chair for feeding, educating, etc. Simultaneously, when the support base 10 and the swing assembly 20 are unlocked, the swing arm 35 can rotate relative to the support base 10, allowing the swing arm 35 to act as the swing arm of the seat 50. This enables the seat 50 to swing relative to the support base 10. Furthermore, the design of the swing arm 35 or the components of the seat 50 ensures that the seat 50 remains horizontal and swings back and forth, better preventing children from falling off. This allows the child seat 100 to function as a rocking chair, facilitating interaction, entertainment, and sleep-inducing activities. Therefore, by utilizing the cooperation between the support base 10 and the swing assembly 20, the child seat 100 can switch between a fixed and swinging state, functioning as both a fixed high chair and a rocking chair. This effectively enriches the functionality of the child seat 100 and improves its safety and structural reliability.

[0041] The technical solution of this utility model utilizes the swing component 20 in conjunction with the support base 10. When the child seat 100 is in a fixed state, the locking connection between the swing component 20 and the support base 10 keeps the swing arm 35 and the seat 50 fixed relative to the support base 10, achieving a fixed seat configuration for the child seat 100. Furthermore, when the child seat 100 is in a swinging state, the unlocking of the swing component 20 and the support base 10 allows the swing arm 35 to rotate relative to the support base 10, causing the seat 50 to swing and achieving a rocking chair configuration for the child seat 100. The structural design of the swing arm 35 or the balancing design of the seat 50 ensures that the seat 50 remains horizontal during the swinging process, preventing it from tilting in the swing direction and reducing the risk of falling off. Furthermore, the child seat can be adjusted by the cooperation of the swing component 20 and the support seat 10 to realize the transformation of the seat shape, which can greatly enhance the functionality of the child seat 100, enabling the child seat 100 to meet the usage needs in various scenarios and effectively improve the practicality and reliability of the child seat 100.

[0042] See Figure 3In one embodiment of this utility model, the swing arm 35 includes a first swing arm 351 and a second swing arm 353, which are respectively rotatable relative to the support base 10. The first swing arm 351 and the second swing arm 353 are respectively connected to the seat 50. The rotation center axis of the first swing arm 351 and the rotation center axis of the second swing arm 353 are parallel; and / or, the first swing arm 351 and the second swing arm 353 are arranged relatively parallel to each other.

[0043] In some embodiments, the rocker arm 35 may include a first rocker arm 351 and a second rocker arm 353. By rotatably connecting one end of the first rocker arm 351 and one end of the second rocker arm 353 to the support base 10, the first rocker arm 351 and the second rocker arm 353 can be connected to the seat 50. When the child seat 100 is in a rocking state, the seat 50 can be stably rocked relative to the support base 10 with the first rocker arm 351 and the second rocker arm 353, realizing the rocker function of the child seat 100. The use of the first rocker arm 351 and the second rocker arm 353 can better support the seat 50, further improving the structural stability and reliability of the child seat 100.

[0044] By setting the rotation center axis of the first swing arm 351 and the rotation center axis of the second swing arm 353 parallel to each other, it is beneficial to make the rotation trajectory of the first swing arm 351 overlap and intersect with the rotation trajectory of the second swing arm 353. This can better ensure that the seat 50 can maintain horizontal swing during the rotation of the first swing arm 351 and the second swing arm 353, better avoid the seat 50 from tilting when swinging, and further improve the overall structural stability and reliability of the child seat 100.

[0045] In some embodiments, by arranging the first swing arm 351 and the second swing arm 353 relatively parallel, the connection structure of the first swing arm 351, the second swing arm 353, the support seat 10, and the seat 50 can form a parallelogram structure. This allows the first swing arm 351 and the second swing arm 353 to maintain a relatively parallel rotational posture, thereby allowing the seat 50 to remain horizontal as it swings with the first swing arm 351 and the second swing arm 353, better preventing the seat 50 from tilting during the swing, further reducing the safety hazards of the child seat 100, and improving the practicality and structural reliability of the child seat 100.

[0046] See Figure 4 and Figure 5 In one embodiment of the present invention, the child seat 100 further includes a second locking component 13 disposed between the support base 10 and the swing component 20. The second locking component 13 is used to lock the swing component 20 and the support base 10, so that the child seat 100 is in a fixed state.

[0047] In this embodiment, the second locking component 13 can be disposed between the support base 10 and the seat 50, or between the support base 10 and the swing arm 35, or between the support base 10, the seat 50, and the swing arm 35. The second locking component 13 can be a fastening structure such as a snap-fit, latch, or bolt assembly that is easy to install and remove. It can be used to securely connect the support base 10 and the swing assembly 20, thus fixing the child seat 100 in a fixed state. Simultaneously, when it is necessary to switch the usage state of the child seat 100, the second locking structure can be operated to unlock the swing assembly 20 and the support base 10, making the child seat 100 easier to operate and use, further improving the practicality and structural reliability of the child seat 100.

[0048] See Figures 2 to 4 In one embodiment of this utility model, the swing assembly 20 further includes a second connector 33, which is disposed at one end of the swing rod 35. The seat 50 is slidably disposed along the extending direction of the swing rod 35, and the seat 50 is detachably connected to the second connector 33. Alternatively, the support base 10 is provided with a first connector 31, one end of the swing rod 35 is rotatably connected to the first connector 31, and the seat 50 is detachably connected to the first connector 31.

[0049] In some embodiments, by providing a second connector 33 at one end of the swing arm 35, which can be a block structure on the swing arm 35, the seat 50 can be slidably positioned along the extension direction of the swing arm 35. The height of the seat 50 on the support base 10 can be adjusted by sliding the seat 50, which helps the child seat 100 meet various seat height requirements and improves its functionality. Simultaneously, the adjustable height of the seat 50 allows it to slide along the swing arm 35 to a lower position when the child seat 100 is in a swinging state, facilitating more stable swinging and further improving the safety and practicality of the child seat 100. The seat 50 can be equipped with fastening components such as buckles, locks, and screws that cooperate with the second connector 33, so that the seat 50 can be assembled and disassembled with the second connector 33. The second connector 33 can be used to limit the position of the seat 50, so that when the swing arm 35 is fixed relative to the support seat 10, it can be fixed with the seat 50 by cooperating with the second connector 33. When the swing arm 35 is rotatable relative to the support seat 10, it can ensure the stable swing of the seat 50 driven by the swing arm 35, further improving the structural stability and reliability of the child seat 100.

[0050] In some embodiments, the first connector 31 can be a structural component connecting the support base 10 and the swing arm 35. A rotating shaft or universal joint can be provided within the first connector 31 to connect with the swing arm 35, enabling rotation of the swing arm 35. Alternatively, the first connector 31 can be fixedly mounted on the support base 10, with one end of the swing arm 35 rotatably connected to the first connector 31. Or, the first connector 31 can be rotatably connected to the support base 10 and rotatably connected to one end of the swing arm 35. The first connector 31 can be a block structure with a certain structural strength. This application does not limit the structural form or arrangement of the first connector 31.

[0051] By detachably connecting the first connector 31 to the seat 50, the seat 50 can be fixed to the first connector 31, achieving a fixed state for the child seat 100. At the same time, the seat 50 can be disconnected from the first connector 31, so that the swing arm 35 can stably drive the seat 50 to swing, further improving the structural stability and reliability of the child seat 100.

[0052] In some embodiments, a slider 51 may be provided on the side wall of the seat 50 facing the support base 10. The slider 51 may be an injection-molded sliding block, and a through hole may be provided inside the slider 51 to engage with the rocker arm 35, so that the sliding direction of the slider 51 is parallel to the axis of the rocker arm 35. The slider 51 and the first connecting member 31 can be detachably connected by fasteners such as pins, bolts, and screws; or they can be detachably connected by a snap-fit ​​structure such as a buckle or slot. There are many ways to detach the slider 51 and the first connecting member 31, and this application does not limit this. Similarly, the slider 51 and the second connecting member 33 can be detachably connected by fasteners such as pins, bolts, and screws; or they can be detachably connected by a snap-fit ​​structure such as a buckle or slot. There are many ways to detach the slider 51 and the second connecting member 33, and this application does not limit this.

[0053] Furthermore, in some embodiments, the swing assembly 20 further includes a second connector 33. When the child seat 100 is in the swing state, the seat 50 is fixed to the second connector 33, the second locking assembly is in the unlocked state, and the swing arm 35 can rotate relative to the support seat 10. The second locking assembly 13 includes a second locking member disposed on one of the support seat 10 and the second connector 33, and a mating part disposed on the other of the support seat 10 and the second connector 33. The second locking member can be fixed to or disengaged from the mating part.

[0054] Using the above method, the mating part and the second locking member can be mated with a pin and a locking hole, or they can be mated with a bolt and a threaded hole, or they can be mated with a buckle structure, etc. By using the mating part and the second locking member to lock and unlock the second locking assembly 13, the ease of operation of the child seat 100 can be improved, and the practicality and structural reliability of the child seat 100 can be further improved.

[0055] In some embodiments, the second locking member can be disposed on the support base 10, the mating part can be disposed on the swing arm 35, or it can be disposed on the seat 50, or it can be disposed on both the swing arm 35 and the seat 50. In this case, the second locking member can be a pin, screw or other structure, and the mating part can be a second locking hole 331. The second locking component 13 is connected to the support base 10 and the swing component 20 by the mating and insertion of the second locking member and the second locking hole 331.

[0056] See Figure 3 and Figure 4 In one embodiment of the present invention, a limiting part 40 is provided on the support base 10. The limiting part 40 is provided on at least one side of the first swing rod 351 or the second swing rod 353, and is used to limit the rotation angle of the first swing rod 351 or the second swing rod 353.

[0057] In this embodiment, the limiting part 40 can be a limiting component on the support base 10 corresponding to the rotation path of the swing arm 35. The limiting part 40 can be located on at least one side of the first swing arm 351, or on at least one side of the second swing arm 353, or on at least one side of both the first swing arm 351 and the second swing arm 353. When the swing arm 35 rotates to a certain angle, the limiting part 40 can be used to abut and limit the swing arm 35, effectively preventing the swing arm 35 from rotating too much, ensuring the stable swing of the seat 50, and further improving the structural stability and reliability of the child seat 100.

[0058] Furthermore, in some embodiments, when the first rocker arm 351 or the second rocker arm 353 abuts against the limiting part 40, the second locking member is opposite to the mating part. The child seat 100 can be designed to cooperate with the support base 10 and the swing assembly 20. When the limiting part 40 abuts against the rocker arm 35, the second locking member is opposite to the mating part. This allows for easier locking of the second locking member and the mating part, achieving the locking and fixing effect of the second locking assembly 13 on the support base 10 and the swing assembly 20, thus improving the ease of operation and practicality of the child seat 100.

[0059] Furthermore, in some embodiments, the limiting part 40 is disposed between the first rocker arm 351 and the second rocker arm 353. This allows for better utilization of the gap between the first rocker arm 351 and the second rocker arm 353, resulting in a more compact overall component design for the child seat 100. Simultaneously, the limiting part 40 can better engage and limit the first rocker arm 351 and the second rocker arm 353, further improving the practicality and structural reliability of the child seat 100. The limiting part 40 can be a triangular block structure, allowing it to use its two inclined sides to limit the first rocker arm 351 and the second rocker arm 353 respectively, further improving the stability of the rocker arm 35's rotation.

[0060] In some embodiments, refer to Figure 4 and Figure 5 As shown, when the support base 10 is provided with a stand 11, and a second connecting member 33 connected to the support base 10 is provided at one end of the swing rod 35, the second locking assembly 13 can be connected to the stand 11. The second locking assembly 13 can be provided with a second pin 1331, which can extend or retract into the side of the stand 11 facing the second connecting member 33. The second connecting member 33 is provided with a second locking hole 331, and the second pin 1331 can be inserted into the second locking hole 331; or, the seat 50 is provided with a second locking hole 331, and the second pin 1331 can be inserted into the second locking hole 331; or, both the seat 50 and the second connecting member 33 can be provided with interconnected second locking holes 331, so that the second pin 1331 can be simultaneously inserted into the second connecting member 33 and the seat 50. That is, the second locking member can include the second pin 1331, and the second locking hole 331 can form a mating part to realize the mating installation of the second locking assembly 13.

[0061] The second locking assembly 13 can refer to a locking mechanism that achieves the extension and retraction of the second pin 1331 through mechanical linkage. Specifically, it can be a sliding mechanism that drives the second pin 1331 to move axially; or it can be a knob that controls the extension or retraction of the second pin 1331. The second pin 1331 can refer to a rigid component used to insert into the locking hole of the second connector 33, specifically a columnar plastic rod, etc.

[0062] Specifically, when the child seat 100 is in a fixed seat position, the second locking assembly 13 can be used to extend the second pin 1331 out of the side wall of the support frame 11 and engage it with the second latch 331, thus fixing the second connector 33 or the seat 50 to the support frame 11 and restricting the seat 50 from swinging with the rocker arm 35. When it is necessary to convert the child seat 100 into a rocker position, the second locking assembly 13 can be operated to move the second pin 1331 axially back, releasing the locking connection between the second connector 33 or the seat 50 and the support frame 11, thereby releasing the rotation restriction of the rocker arm 35. This allows the rocker arm 35 to rotate relative to the support seat 10, and the seat 50 can then be connected to the second connector 33, allowing the seat 50 to swing stably back and forth relative to the support seat 10, further improving the practicality and structural reliability of the child seat 100.

[0063] See Figure 10 and Figure 11 In one embodiment of this utility model, the second locking member includes a mounting cylinder 131, a second translation block 133, a second elastic member 135, and a knob member 137. The mounting cylinder 131 has a first inner wall and a second inner wall with opposite sides. The first inner wall is provided with a first clearance hole 1315, and the second inner wall is provided with a second clearance hole 1319. The second translation block 133 is disposed inside the mounting cylinder 131 and is movably disposed along the axis of the mounting cylinder 131. A second pin 1331 is provided on one side of the second translation block 133, and the second pin 1331 can pass through the first clearance hole 1315. The second elastic member 135 is disposed inside the mounting cylinder 131 and is sleeved on the second pin 1331. The two ends of the second elastic member 135 abut against or connect with the second translation block 133 and the first inner wall, respectively. The knob member 137 is rotatably disposed through the second clearance hole 1319. The second translation block 133 has a second inclined wall 1333 facing the knob 137 on its periphery. The second inclined wall 1333 is inclined along the axial direction of the mounting cylinder 131. The knob 137 is provided with a second boss 1371, which abuts against the second inclined wall 1333.

[0064] In this embodiment, when the support base 10 is provided with a stand 11, the mounting cylinder 131 can refer to a cylindrical structure connected to the support base 10 or the swing assembly 20. Specifically, it can be a hollow cylinder structure used to accommodate the second translation block 133 and the second elastic member 135. The first clearance hole 1315 and the second clearance hole 1319 on the mounting cylinder 131 form a pin movement channel and a mounting position for the knob member 137. The second translation block 133 can refer to a component that slides along the axial direction of the mounting cylinder 131. Specifically, it can be a block structure with the second pin 1331 connected to the side. The extension direction of the second pin 1331 on the second translation block 133 can be perpendicular to the stand 11 to better achieve the snap-fit ​​fixation with the second connecting member 33. The second elastic element 135 can refer to a component that provides a restoring force, specifically a coil spring, elastic colloid, torsion spring, etc. Using the second elastic element 135 fitted onto the outer wall of the second pin 1331 can save space, and the second pin 1331 can guide the deformation of the second elastic element 135. The knob 137 can refer to an exposed operating component. The second protrusion 1371 on the knob 137 forms an inclined surface engagement with the second inclined wall 1333 of the second translation block 133. This allows the second protrusion 1371 to slide along the second inclined wall 1333 as the knob 137 rotates. This allows the second protrusion 1371 to push the second translation block 133 away from the knob 137 during rotation, enabling the second pin 1331 to stably engage with the second locking hole 331, thus locking the second connecting block to the support frame 11.

[0065] Specifically, when it is necessary to lock the swing assembly 20 to the support base 10, the knob 137 can be rotated counterclockwise so that the second boss 1371 slides along the second inclined wall 1333, so that the second boss 1371 pushes the second translation block 133 away from the knob 137 and causes the second translation block 133 to compress the second elastic member 135 to undergo elastic compression deformation, so that the second pin 1331 can extend and be inserted into the second locking hole 331 as the second translation block 133 moves. When it is necessary to release the lock between the second connector 33 and the stand 11, the knob 137 can be rotated clockwise in the opposite direction. At this time, the second boss 1371 slides in the opposite direction on the second inclined wall 1333 to release the push on the second translation block 133, thereby restoring the elastic deformation of the second elastic element 135. The rebound force of the second elastic element 135 drives the second translation block 133 to reset, and the second pin 1331 retracts into the mounting cylinder 131 with the movement of the second translation block 133, releasing the insertion of the second pin 1331 into the second locking hole 331, realizing the state switching of the child seat 100. In this process, the rotation angle of the knob 137 and the displacement of the second translation block 133 can be proportionally related through the inclined plane cooperation to achieve precise control of the extension and retraction of the second pin 1331. Through the combined design of rotary drive and inclined plane transmission, the rotational action is converted into the linear displacement of the second pin 1331, which can achieve precise control of the displacement while reducing the operating force. The second locking component 13 achieves effortless operation and reliable locking, significantly improving user convenience while ensuring connection reliability.

[0066] See Figure 10 and Figure 11 In one embodiment of the present invention, the mounting cylinder 131 further has a third inner wall connecting the first inner wall and the second inner wall. The third inner wall is provided with a guide protrusion 1317, and the periphery of the second translation block 133 is provided with a guide groove 1335. The guide protrusion 1317 and the guide groove 1335 are engaged and inserted into each other.

[0067] In this embodiment, the third inner wall can refer to the side wall structure inside the mounting cylinder 131 that connects the first inner wall and the second inner wall. The guide protrusion 1317 can refer to a strip-shaped or block-shaped protrusion extending from the surface of the third inner wall. Specifically, it can be processed by stamping and is used to cooperate with the guide groove 1335 to guide and limit the movement trajectory of the second translation block 133. The guide groove 1335 can refer to a groove structure formed on the periphery of the second translation block 133. Specifically, it can be formed by milling and its shape matches the guide protrusion 1317. It is used to guide the second translation block 133 to move linearly along the axial direction of the mounting cylinder 131 and prevent rotational deviation.

[0068] Specifically, in the second locking assembly 13, the second translation block 133 is constrained inside the mounting cylinder 131, and its peripheral guide groove 1335 forms a sliding fit with the guide protrusion 1317 on the third inner wall. When the knob 137 is rotated, the second boss 1371 abuts against the second inclined wall 1333, causing the second translation block 133 to move axially along the mounting cylinder 131. At this time, the guide protrusion 1317 is embedded in the guide groove 1335, which can limit the second translation block 133 from circumferential rotation or radial displacement, ensuring that the second pin 1331 is accurately inserted into or withdrawn from the second locking hole 331 along a straight path, thus realizing the stable operation of the second locking assembly 13.

[0069] Through the above technical solution, this embodiment achieves precise guidance of the second translation block 133 during the locking and unlocking process, avoids the problem of misalignment of the pin and the locking hole caused by component offset, makes the disassembly operation of the child seat 100 smoother and more reliable, and further improves the ease of operation of the child seat 100.

[0070] See Figure 5 , Figure 10 and Figure 11 In one embodiment of the present invention, the mounting cylinder 131 includes a cylinder body 1311 and a cover plate 1313. One end of the cylinder body 1311 is provided with a first clearance hole 1315, and the other end of the cylinder body 1311 is provided with an opening. The cover plate 1313 is connected to the cylinder body 1311 and covers the opening. The cover plate 1313 is provided with a second clearance hole 1319. The knob 137 abuts against the cover plate 1313.

[0071] In this embodiment, the cylinder 1311 can refer to a cylindrical shell used to accommodate the second translation block 133 and the second elastic member 135. Specifically, it can be manufactured using injection molding. The inner bottom wall of the cylinder 1311 can form the first inner wall of the mounting cylinder 131. The inner cavity shape of the cylinder 1311 can match the outer contour of the second translation block 133 to achieve a certain guiding function. The cover plate 1313 can refer to a plate-shaped component that closes the opening of the cylinder 1311. Specifically, it can be connected to the cylinder 1311 by a snap or screw. The cover plate 1313 can form the second inner wall of the mounting cylinder 131. The second clearance hole 1319 provided on the cover plate 1313 allows the knob 137 to pass through, so that the knob 137 can be exposed for easy user operation.

[0072] Specifically, the mounting cylinder 131, through the design of a split cylinder 1311 and a cover plate 1313, allows the second translation block 133, the second elastic element 135, and the knob 137 to be inserted into the inner cavity of the cylinder 1311 from the opening. Then, the opening is closed by the cover plate 1313 to form a certain sealing structure of the cylinder 1311. Part of the structure of the knob 137 can pass through the second clearance hole 1319 of the cover plate 1313 and be exposed on the outside of the cover plate 1313 so that the user can operate and twist it. When the knob 137 is rotated, the second boss 1371 can slide along the inclined wall, pushing the second translation block 133 to move along the axis of the mounting cylinder 131, thereby realizing the extension or retraction of the second pin 1331.

[0073] In some specific embodiments, the connection between the cylinder 1311 and the cover plate 1313 can be a snap-fit ​​structure. For example, an annular groove is provided on the open edge of the cylinder 1311, and a corresponding rib is provided on the edge of the cover plate 1313. The rib is fixed by rotating the cover plate 1313 so that it is snapped into the groove. Of course, there are many ways to connect the cylinder 1311 and the cover plate 1313, and this application does not limit this one.

[0074] The design of the split cylinder 1311 and cover plate 1313 allows the second translation block 133 and the second elastic element 135 to be disassembled and installed separately, effectively reducing manufacturing difficulty and maintenance costs. At the same time, the axial limit of the cover plate 1313 on the knob 137 avoids the risk of the knob 137 coming off during use, realizing quick disassembly and convenient maintenance of the second locking assembly 13, further improving the practicality and structural reliability of the child seat 100.

[0075] See Figure 2 , Figure 4 and Figure 5 In one embodiment of this utility model, the support base 10 is provided with a first connecting member 31, and the swing assembly 20 further includes a second connecting member 33. When the child seat 100 is in a fixed state, the second locking assembly 13 is in a locked state, and the seat 50 is fixed to the first connecting member 31 or the second connecting member 33. The child seat 100 also includes a first locking assembly disposed between the first connecting member and the seat 50. The child seat 100 also includes an unlocking member disposed on the first connecting member 31 or the seat 50, for driving the first locking assembly to unlock.

[0076] Using the above solution, the first locking component can be a fastening structure such as a buckle, latch, or bolt assembly, and the unlocking component can be a linkage structure that can drive the first locking component to move. For example, it can be a handle 5373 connected to the first locking component in the form of a buckle or latch, or a push button connected to the first locking component in the form of a pin or bolt assembly. The first connecting piece 31 and the seat 50 can be easily disassembled and assembled by operating the first locking component and the unlocking component, so as to realize the convenient switching of the state of the child seat 100, further improving the practicality and structural reliability of the child seat 100.

[0077] In some embodiments, the first locking assembly includes a first locking member and a first locking hole 311. The first locking member can be movably mounted on the seat 50, for example, it can be connected to the slider 51. The first locking member has a first pin 5331, which can extend or retract into the side of the slider 51 facing the first connector 31. The first locking hole 311 can be located on the first connector 31, and the first pin 5331 can be inserted into the first locking hole 311. In this case, the unlocking member can be a handle rotatably mounted on the seat 50. By operating the handle on the seat 50, the first locking member can be engaged or disengaged from the first locking hole 311, thus facilitating the assembly and disassembly of the seat 50 and the first connector 31.

[0078] The first locking assembly can refer to a mechanical structure that enables a detachable connection between the slider 51 and the first connecting member 31. Specifically, it can be implemented using a locking structure that uses a pin and a locking hole. The pin is inserted into the locking hole to form a physical limit. This first locking assembly can be installed inside the slider 51, with the first pin 5331 passing through the side wall of the slider 51; or it can be connected and installed on the outside of the slider 51. The first pin 5331 can refer to a columnar component with axial movement capability, specifically made of metal or high-strength plastic, which controls the switching of the connection state through extension or retraction. The first locking hole 311 on the first connecting member 31 can refer to a hole structure that matches the shape of the pin, specifically in the form of a through hole or a blind hole, and its position corresponds to the movement trajectory of the pin in the extended state.

[0079] Specifically, when the slider 51 slides along the rocker arm 35 to be opposite the first connecting member 31, the first pin 5331 can be inserted into the first locking hole 311 of the first connecting member 31 to form a rigid connection, thereby locking the slider 51 and the first connecting member 31. To release the connection, the first locking assembly can be controlled to retract the first pin 5331, disengaging it from the locking hole and releasing the lock between the slider 51 and the first connecting member 31. It should be noted that the first locking assembly can utilize a sliding structure to extend or retract the first pin 5331; alternatively, the first locking assembly can utilize a knob to control the extension or retraction of the first pin 5331; or alternatively, an electric push rod can be used to control the extension or retraction of the first pin 5331. There are many structural forms for the first locking assembly, and this application does not limit this one, as long as it can drive the first pin 5331 to move. The axial movement trajectory of the pin can be perpendicular to the extension direction of the rocker arm 35, ensuring that there is no relative displacement between the slider 51 and the rocker arm 35 in the connected state.

[0080] By using the first pin 5331 to engage with the first slot 311, the slider 51 and the first connector 31 can form a three-point force-bearing structure, effectively dispersing the load from the seat 50, ensuring the overall structural stability of the child seat 100 in a fixed seat configuration, and further improving the practicality and structural reliability of the child seat 100.

[0081] See Figures 7 to 9 In one embodiment of this utility model, the first locking component includes a support shaft 531, a first translation block 533, and a first elastic element 535. The support shaft 531 includes a base plate 5311 and a shaft body 5313, with the shaft body 5313 connected to the base plate 5311. The first translation block 533 is sleeved on the shaft body 5313 and is movably disposed along the axial direction of the shaft body 5313. A first pin 5331 is provided on one side of the first translation block 533. The first elastic element 535 is sleeved on the shaft body 5313, with both ends of the first elastic element 535 abutting or connecting to the base plate 5311 and the first translation block 533, respectively. The unlocking component also includes a movable turntable 537 connected to the handle 137, which is rotatably connected to one end of the shaft body 5313. The first translation block 533 has a groove 5333 on the side facing the movable turntable 537. The groove 5333 has a first inclined wall 5335 facing the movable turntable 537. The first inclined wall 5335 is inclined along the axial direction of the shaft 5313. The movable turntable 537 has a first boss 5371 on one side. The first boss 5371 is inserted into the groove 5333 and abuts against the first inclined wall 5335.

[0082] In this embodiment, the support shaft 531 can guide the axial support structure that supports the movement of the first translation block 533. Specifically, it can be integrally formed by a plastic rod and a base plate 5311. The shaft 5313 can provide a track for the movement of the first translation block 533, and the base plate 5311 can limit the movement range of the translation block. The first translation block 533 can refer to a locking actuator that moves axially. Specifically, it can be a block structure with a first pin 5331 on its side, and the extension and retraction state of the first pin 5331 can be controlled by axial displacement. The first elastic element 535 can refer to a buffer element that provides a restoring force. Specifically, it can be a coil spring, elastic colloid, torsion spring, etc., and can maintain the locked position of the pin by a pre-compression state. The movable turntable 537 refers to a rotation control component that drives the translation block. Specifically, it can be a disc structure with a first boss 5371, and can convert the circumferential motion into the axial displacement of the first boss 5371 by changing the rotation angle, thereby realizing the extension and retraction drive of the first translation block 533. The groove 5333 on the first translation block 533 and the first inclined wall 5335 inside the groove 5333 refer to the inclined surface mating structure that realizes motion conversion. The first boss 5371 of the movable turntable 537 passes through the groove 5333 and abuts against the first inclined wall 5335. The first boss 5371 can slide along the first inclined wall 5335 as the movable turntable 537 rotates. Thus, the first boss 5371 can push the first translation block 533 away from the movable turntable 537 during rotation, converting the rotation angle of the turntable into the linear displacement of the translation block, so that the first pin 5331 can be stably inserted into the first locking hole 311 to lock the first connecting block and the slider 51.

[0083] Specifically, when the movable turntable 537 is rotated, the first boss 5371 slides against the first inclined wall 5335 of the slide groove 5333, forcing the first translation block 533 to move away from the movable turntable 537 along the axial direction of the shaft 5313. At this time, the first elastic element 535 can be compressed by the pressure of the first translation block 533, and the first pin 5331 moves synchronously with the first translation block 533 to achieve a retraction action. When the movable turntable 537 is rotated in the opposite direction, the first boss 5371 slides in the opposite direction along the first inclined wall 5335 and inserts into the slide groove 5333, which can remove the pushing force of the movable turntable 537 on the first translation block 533. At this time, the first elastic element 535 restores its elastic deformation, so that the rebound force of the first elastic element 535 pushes the translation block to reset, and the first pin 5331 extends out of one side of the slider 51 again. In this process, the rotation angle of the movable turntable 537 and the displacement of the first translation block 533 can be proportionally related through the inclined plane, achieving precise control of the extension and retraction of the first pin 5331. Through the combined design of rotary drive and inclined plane transmission, the rotational motion is converted into the linear displacement of the first pin 5331, achieving precise control of the displacement while reducing operating force. This realizes effortless operation and reliable locking of the first locking assembly, significantly improving user convenience while ensuring connection reliability.

[0084] See Figure 6 and Figure 7 In some embodiments, a handle 5373 is connected to the periphery of the movable turntable 537. The handle 5373 extends out of the outside of the slider 51 and can drive the movable turntable 537 to rotate.

[0085] In this embodiment, the handle 5373 connected to the periphery of the movable turntable 537 can refer to the operating component located on the outer circumference of the turntable. Specifically, it can be connected to the turntable body by a snap-fit ​​mechanism to transmit rotational force. The handle 5373 extending outward from the slider 51 allows the operating component of the first locking assembly to extend beyond the outer shell of the slider 51. This can be achieved by creating a through hole or notch in the side wall of the slider 51, facilitating direct contact and operation by the user on the seat 50.

[0086] Specifically, when it is necessary to release the lock between the slider 51 and the first connecting member 31, the user can apply rotational force by grasping the exposed handle 5373, causing the movable turntable 537 to rotate around the shaft 5313. This causes the first boss 5371 of the movable turntable 537 to generate an axial force on the first inclined wall 5335 of the slide groove 5333, pushing the first translation block 533 to compress the first elastic member 535, causing the first pin 5331 to retract from the first locking hole 311. At this time, the slider 51 can slide along the rocker arm 35 or separate from the first connecting member 31. When releasing the handle 5373, the elastic force of the first elastic member 535 can be used to push the first translation block 533 back to its original position, or the user can grasp the handle 5373 and rotate it in the opposite direction to allow the first translation block 533 to better return to its original position under the elastic force of the first elastic member 535, allowing the first pin 5331 to re-insert into the first locking hole 311 to complete the locking. Furthermore, by designing an external rotating handle 5373 on the slider 51, the child seat 100 can be operated more intuitively to change its form, further improving the ease of operation and practicality of the child seat 100.

[0087] By adopting the above solution, the first locking component provided in the seat 50 and the first locking hole 311 provided in the first connecting component 31 are engaged to form a first locking assembly. The first locking component includes a support shaft 531, a first translation block 533, and a first elastic component 537. The unlocking component is formed by a movable turntable 537 provided in the seat 50 and a handle 5373 connected to the movable turntable 537. The movable turntable 537 is linked to the first locking component. The handle 5373 can be operated on the seat 50 to drive the movable turntable 537 to rotate. The movable turntable 537 and the first elastic component 535 can drive the first locking component to extend or retract the first pin 5331, realizing the stable assembly and disassembly of the seat 50 and the first connecting component 31. This ensures the convenient operation of the child seat 100 and further improves the practicality and structural reliability of the child seat 100.

[0088] See Figure 2 and Figure 5 In one embodiment of the present invention, the slider 51 is provided with a fixing slot 511 on the side facing the second connector 33, and the second connector 33 can be inserted into the fixing slot 511.

[0089] In this embodiment, the fixed slot 511 can refer to the groove structure provided on the bottom surface of the slider 51. Specifically, it can be implemented by a U-shaped groove with a guide opening. Limiting protrusions or snap-fit ​​surfaces can be provided inside the fixed slot 511 to constrain the degree of freedom of movement of the second connector 33, so as to achieve a more stable connection and locking between the slider 51 and the second connector 33.

[0090] Specifically, the slider 51 has a fixing slot 511 on the side facing the second connector 33. When the slider 51 slides along the rocker arm 35 to the position of the second connector 33, the second connector 33 is inserted into the fixing slot 511, and the locking of the slider 51 and the second connector 33 is achieved by the engagement of the second connector 33 and the fixing slot 511. Furthermore, when the second connector 33 is disconnected from the stand 11, the seat 50 and the second connector 33 can swing together with the rocker arm 35, achieving a more stable rocking chair function for the child seat 100. When the second connector 33 is inserted into the fixing slot 511, its end is restricted from lateral displacement by the side wall of the slot. Simultaneously, a limiting structure can be provided inside the fixing slot 511 to prevent the second connector 33 from axially disengaging, improving the connection stability between the second connector 33 and the slider 51. During disassembly, the connection can be released by applying external force to slide the end of the second connector 33 out of the slot, achieving a more convenient seat configuration change operation.

[0091] Furthermore, compared to detachable connection methods that use bolt fastening or complex locking mechanisms, the direct insertion and engagement of the fixing slot 511 with the second connector 33 can greatly simplify the connection operation process, reduce the number of parts, and further improve the practicality and ease of operation of the child seat 100.

[0092] When the second connector 33 is detachably connected to the frame 11 via fastening structures such as pins, bolts, and screws, a clearance hole structure with a connecting fixing slot 511 can be provided on the side of the slider 51 facing the frame 11. This allows the slider 51 to slide to engage with the second connector 33, thus avoiding the connection structure between the second connector 33 and the frame 11. This ensures a stable connection and locking between the slider 51 and the second connector 33, further improving the overall structural stability and reliability of the child seat 100.

[0093] See Figure 2 and Figure 6 In one embodiment of the present invention, the slider 51 is provided with a guide hole 513, the rocker arm 35 passes through the guide hole 513, and the slider 51 is slidably disposed on the rocker arm 35.

[0094] In this embodiment, the guide hole 513 refers to a through hole formed inside the slider 51 and extending along the extension direction of the rocker arm 35. Specifically, it can be implemented using a circular, elliptical, or rectangular hole structure, or it can be set to correspond to the cross-sectional shape of the rocker arm 35, so that the guide hole 513 can cooperate with the rocker arm 35 to limit its movement and ensure the guided sliding of the slider 51 along the extension direction of the rocker arm 35. The inner wall of the guide hole 513 can be provided with a low-friction material layer to reduce the sliding friction resistance with the rocker arm 35.

[0095] Specifically, the slider 51 is sleeved on the outer surface of the rocker arm 35 through the guide hole 513. The inner wall of the guide hole 513 can contact the outer wall of the rocker arm 35, restricting the slider 51 to move only along the axial direction of the rocker arm 35, reducing the offset or shaking of the slider 51 during sliding, thereby helping to reduce the sliding wear of the slider 51 and better improve the service life of the child seat 100.

[0096] When the slider 51 is provided with a fixing slot 511 on the side facing the second connector 33 and is engaged and disassembled with the second connector 33, the guide hole 513 can be connected to the fixing slot 511 so that when the slider 51 slides along the extension direction of the rocker arm 35, the fixing slot 511 and the second connector 33 can be better aligned and engaged, further improving the overall structural stability and reliability of the child seat 100.

[0097] By connecting the guide hole 513 with the rocker arm 35, a precise axial sliding constraint can be formed, which not only prevents the slider 51 from disengaging from the rocker arm 35, but also reduces frictional loss caused by lateral force, effectively improving the smoothness of operation and structural reliability when the child seat 100 changes form.

[0098] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
