Description

[Technical Field]

[0001] This application belongs to the field of automotive child seat technology, specifically relating to an automotive child seat with an ISOFIX rotation positioning structure. [Background Technology]

[0002] Traditional ISOFIX connectors are typically fixed structures, and their installation angle cannot be adaptively adjusted according to the actual tilt angle of the vehicle seat. Due to differences in seat back angles, seat cushion curvatures, and ISOFIX anchor point positions among different vehicle models, it is difficult for child safety seats to fit snugly against the vehicle seat surface during installation. This can easily lead to gaps or localized stress concentrations, reducing connection stability and even affecting the energy transfer path during a collision, thus weakening the safety protection effect. At the same time, traditional ISOFIX connecting rods still protrude significantly from the child safety seat base when not in use. Their hard metal parts can easily cause accidental scratches and damage to occupants or items inside the vehicle, and the exposed mechanical structure disrupts the overall appearance of the seat. [Utility Model Content]

[0003] To address the problem that traditional ISOFIX connectors for child car seats cannot be properly adapted to different car models during installation, resulting in an incompatible fit with the seat, this application provides a car child seat with an ISOFIX rotation positioning structure.

[0004] This application is achieved through the following technical solution:

[0005] A car child seat with an ISOFIX rotation positioning structure includes a seat body, a connector body hinged to both sides of the seat body, a limiting member disposed on the seat body and corresponding to the connector body, an adjustment mechanism connected to the limiting member and adjusting the connector body relative to the seat body between an unfolded and a folded state, and a release mechanism connected to the connector body and used to limit or release the positioning of the connector body relative to the seat body.

[0006] As described above, a car child seat with an ISOFIX rotation positioning structure includes an adjustment mechanism comprising a limiting rod connected at both ends to the connector bodies on both sides, and a limiting groove disposed on the limiting member for the limiting rod to pass through and rotate with the connector body. The limiting rod is provided with a limiting protrusion, and the limiting member is provided with a limiting hole for the limiting protrusion to be inserted.

[0007] As described above, a car child seat with an ISOFIX rotation positioning structure includes a release mechanism comprising a button slidably disposed on the connector body and abutting against the limiting rod. A first elastic element is provided between the button and the limiting rod. The button is used to drive the limiting protrusion out of the limiting hole to release the restriction on the sliding of the limiting rod along the limiting groove. The first elastic element is used to drive the limiting protrusion into the limiting hole to restrict the sliding of the limiting rod along the limiting groove.

[0008] As described above, a car child seat with an ISOFIX rotation positioning structure has a relief groove on the limiting rod for moving within the limiting groove and the limiting hole, the relief groove being located on both sides of the limiting protrusion.

[0009] As described above, a car child seat with an ISOFIX rotation positioning structure has limiting holes at both ends of the limiting groove corresponding to the unfolded and retracted states of the connector body, and a plurality of limiting holes along the limiting groove are also provided at the end of the limiting hole near the unfolded state.

[0010] As described above, a car child seat with an ISOFIX rotation positioning structure further includes a pawl rotatably disposed at the opening of the connector body, a drive member connected to the pawl, and an unlocking mechanism connected to the connector body. The unlocking mechanism includes an unlocking key slidably disposed on the connector body and a pull cable connecting the drive members on both sides. A second elastic member is provided between the unlocking key and the connector body. The unlocking key drives the pull cable to pull the drive member away from the pawl.

[0011] As described above, a car child seat with an ISOFIX rotation positioning structure has a pawl with a holding part, a pushing part, a supporting part for the front end of the drive member to engage, and a pawl opening located between the holding part and the pushing part. The second elastic member drives the drive member to engage with the supporting part.

[0012] As described above, in a car child seat with an ISOFIX rotation positioning structure, the ISOFIX interface pushes against the pushing part, the second elastic member is compressed, the pawl rotates, and the driving member is engaged with the supporting part under the elastic force of the second elastic member. At the same time, the pawl opening cooperates with the body opening to lock the ISOFIX interface. The unlock button drives the pull cable to pull the driving member backward, causing the driving member to be withdrawn from the supporting part to complete the release action.

[0013] As described above, a car child seat with an ISOFIX rotation positioning structure has a push-pull block on the unlock button that abuts against the pull cable, and a limiting block inside the connector body for the pull cable to pass through. After passing the bottom of the push-pull block, the pull cable passes upward through the limiting block towards the unlocking direction of the unlock button.

[0014] As described above, a car child seat with an ISOFIX rotation positioning structure further includes a prompting mechanism for displaying the locked and unlocked states of the unlocking mechanism. The prompting mechanism includes a slider connected to the drive member, the slider having a first area and a second area, and the connector body having a window corresponding to the first area or the second area.

[0015] A car child seat with an ISOFIX rotation positioning structure as described above is characterized in that it includes a seat body, a connector body hinged to both sides of the seat body, an adjustment mechanism for adjusting the connector body relative to the seat body between an unfolded and a retracted state, and a release mechanism for limiting or releasing the restriction of the connector body from maintaining its position relative to the seat body.

[0016] The adjustment mechanism is located between the seat body and the connector body, and includes a limiting rod and a limiting groove through which the limiting rod passes.

[0017] The limiting rod has a first thickness region and a second thickness region, the thickness of the second thickness region being different from the thickness of the first thickness region;

[0018] When the connector body is positioned relative to the seat body, the first thickness region is positioned in the limiting groove;

[0019] When the release mechanism drives the limiting rod to move, the second thickness area slides in the limiting groove, and the connector body can rotate relative to the seat body.

[0020] A car child seat with an ISOFIX rotation positioning structure as described above is characterized in that the limiting rod is provided with a limiting protrusion, and the limiting protrusion is the first thickness area;

[0021] The limiting groove is provided with at least one limiting hole for the limiting protrusion to be inserted;

[0022] When the release mechanism drives the limiting protrusion to disengage from the limiting hole, the restriction on the limiting rod to slide along the limiting groove is released.

[0023] A car child seat with an ISOFIX rotation positioning structure as described above is characterized in that the limiting rod is provided with a clearance groove for moving within the limiting groove and the limiting hole, the clearance groove being the second thickness region, and the clearance groove being located on at least one side of the first thickness region.

[0028] Compared with the prior art, this application has the following advantages:

[0029] This application discloses a car child seat with an ISOFIX rotation positioning structure. It employs a connector body hinged to both sides of the seat body, along with matching limiting components and an adjustment mechanism. This allows the ISOFIX connector to adaptively adjust according to the actual tilt angle of the vehicle seat, and a locking mechanism to fix the current angle.

Detailed Implementation Methods

[0040] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0041] Please see Figures 1 to 9 A car child seat with an ISOFIX rotation positioning structure includes a seat body 1, a connector body 2 hinged to both sides of the seat body 1, a limiting member 3 disposed on the seat body 1 and corresponding to the connector body 2, an adjustment mechanism 4 connected to the limiting member 3 and adjusting the connector body 2 relative to the seat body 1 between an unfolded and a folded state, and a release mechanism 5 connected to the connector body 2 and used to limit or release the positioning of the connector body 2 relative to the seat body 1.

[0042] This application discloses a car child seat with an ISOFIX rotation positioning structure. It employs a connector body hinged to both sides of the seat body, along with matching limiting components and an adjustment mechanism. This allows the ISOFIX connector to adaptively adjust according to the actual tilt angle of the vehicle seat, and a locking mechanism to fix the current angle. This ensures that the seat fits snugly against the vehicle seat surface during installation, avoiding reduced connection stability due to gaps or localized stress concentration. Furthermore, the connector body can be retracted into the seat body, preventing accidental scratches caused by outward protrusion and protecting the safety of occupants and items inside the vehicle. It also enhances the overall appearance of the seat, allowing it to be used as a baby carrier, thus improving the product's aesthetics and user experience.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the adjustment mechanism 4 includes a limiting rod 41 connected at both ends to the two sides of the connector body 2, and a limiting groove 42 provided on the limiting member 3 for the limiting rod 41 to pass through and rotate with the connector body 2. The limiting rod 41 is provided with a limiting protrusion 52, and the limiting member 3 is provided with a limiting hole 53 for the limiting protrusion 52 to be inserted.

[0044] In this embodiment, the limiting rod 41 passes through the limiting groove 42. When the connector body 2 rotates, the limiting rod 41 slides within the limiting groove 42, thereby ensuring that the rotation range of the connector body 2 is limited and avoiding excessive rotation that could lead to unstable connection. This design not only allows the safety seat to be adaptively adjusted according to the seat back angle and cushion curvature of different vehicle models, ensuring full fit with the vehicle seat surface during installation, but also effectively reduces gaps and local stress concentration, improving connection stability. When it is necessary to adjust the angle of the connector body 2, press button 51. Button 51 pushes the limiting rod 41, causing the limiting protrusion 52 to disengage from the limiting hole 53, releasing the restriction on the sliding of the limiting rod 41 within the limiting groove 42. At this time, the angle of the connector body 2 can be freely adjusted. After adjustment, release button 51. The elastic force of the first elastic element 54 pushes the limiting rod 41, causing the limiting protrusion 52 to re-insert into the limiting hole 53, thereby limiting the sliding of the limiting rod 41 and fixing the angle of the connector body 2. This design not only provides a convenient way to adjust the angle, but also ensures the stability after adjustment, preventing the connector body 2 from moving unexpectedly during use and improving the reliability of the safety seat.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, the unlocking mechanism 5 includes a button 51 slidably disposed on the connector body 2 and abutting against the limiting rod 41. A first elastic element 54 is provided between the button 51 and the limiting rod 41. The button 51 is used to drive the limiting protrusion 52 out of the limiting hole 53 to release the restriction on the sliding of the limiting rod 41 along the limiting groove 42. The first elastic element 54 is used to drive the limiting protrusion 52 into the limiting hole 53 to restrict the sliding of the limiting rod 41 along the limiting groove 42.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting rod 41 is provided with a relief groove 411 for moving within the limiting groove 42 and the limiting hole 53, and the relief groove 411 is located on both sides of the limiting protrusion 52.

[0047] In this embodiment, when the installation angle of the child safety seat needs to be adjusted, button 51 is pressed, causing the limiting protrusion 52 to disengage from the limiting hole 53. At this time, the clearance groove 411 of the limiting rod 41 can slide freely along the limiting groove 42 to achieve angle adjustment. After adjusting to the appropriate position, button 51 is released, and the first elastic element 54 pushes the limiting protrusion 52 back into the corresponding limiting hole 53, locking the position of the limiting rod 41. The presence of the clearance groove 411 makes this process smoother and reduces jamming caused by structural interference.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation, the two ends of the limiting groove 42 are respectively provided with limiting holes 53 corresponding to the unfolded state and the retracted state of the connector body 2, and a plurality of limiting holes 53 are also provided along the limiting groove 42 near the end of the limiting hole 53 in the unfolded state.

[0049] In this embodiment, the limiting holes 53 at both ends ensure that the connector body 2 can be stably locked when fully extended and fully retracted. The additional limiting holes 53 provide users with more angle options, allowing the connector body 2 to be finely adjusted according to the seat back angle and cushion curvature of different vehicle models, thereby achieving a tighter fit and a more stable connection. When the connector body 2 rotates to a specific angle, the limiting protrusion 52 on the limiting rod 41 will insert into the corresponding limiting hole 53, locking that angle. Since the limiting holes 53 are distributed along the limiting groove 42, users can adjust the angle of the connector body 2 to allow the limiting protrusion 52 to insert into different limiting holes 53, thereby achieving fine adjustment of the seat angle. This design not only meets the installation requirements of different vehicle models but also improves the stability and comfort of the seat during use.

[0050] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a pawl 63 rotatably disposed at the body opening 62 of the connector body 2, a driving member 64 connected to the pawl 63, and an unlocking mechanism 6 connected to the connector body 2. The unlocking mechanism 6 includes an unlocking key 61 slidably disposed on the connector body 2 and a pull wire 65 connecting the driving members 64 on both sides. A second elastic member 67 is provided between the unlocking key 61 and the connector body 2. The unlocking key 61 drives the pull wire 65 to pull the driving member 64 away from the pawl 63.

[0051] In this embodiment, a convenient unlocking function for the ISOFIX interface is achieved through a sliding unlock button 61 on the connector body 2, a rotating pawl 63 located at the opening 62 of the body, a driving member 64 connected to the pawl 63, and a linkage member 66 connecting the two driving members 64 via a pull cable 65. A second elastic member 67 is also provided between the unlock button 61 and the connector body 2. When the ISOFIX interface needs to be released, the unlock button 61 is pressed. The unlock button 61 pulls the driving member 64 away from the pawl 63 via the pull cable 65. The pawl 63, freed from the constraint of the driving member 64, rotates, thereby releasing the lock on the ISOFIX interface and allowing the user to easily remove the car seat. The second elastic member 67 pushes the unlock button 61 back to its original position after it is released, preparing for the next operation. This design not only simplifies the removal process of the car seat and improves the convenience of user operation, but also ensures the reliability and consistency of the unlocking action. The pressing action of the unlock button 61 is transmitted to the driving member 64 via the pull cable 65, and the movement of the driving member 64 directly affects the rotation state of the pawl 63. When the drive member 64 moves away from the pawl 63, the pawl 63 rotates and releases the ISOFIX interface; when the drive member 64 resets under the action of the second elastic member 67, the pawl 63 returns to the locked state. This linkage design ensures precise control of the unlocking and locking actions, avoiding misoperation or incomplete operation.

[0052] Furthermore, as a preferred embodiment of this solution and not a limitation, the unlocking button 61 is provided with a push-pull block 611 that abuts against the pull wire 65, and the connector body 2 is provided with a limiting block 68 for the pull wire 65 to pass through. After passing the bottom of the push-pull block 611, the pull wire 65 passes upward through the limiting block 68 towards the unlocking direction of the unlocking button 61.

[0053] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a prompting mechanism 7 for displaying the locked and unlocked states of the unlocking mechanism 6. The prompting mechanism 7 includes a slider 71 connected to the drive member 64. The slider 71 has a first region 72 and a second region 73. The connector body 2 has a window 74 corresponding to the first region 72 or the second region 73.

[0057] The limiting rod 41 has a first thickness region 100 and a second thickness region 200, the thickness of the second thickness region 200 being different from the thickness of the first thickness region 100.

[0058] When the connector body 2 is positioned relative to the seat body, the first thickness region 100 is positioned in the limiting groove 42;

[0059] When the release mechanism 5 drives the limiting rod 41 to move, the second thickness area 200 slides in the limiting groove 42, and the connector body 2 can rotate relative to the seat body 1.

[0060] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting rod 41 is provided with a limiting protrusion 52, and the limiting protrusion 52 is the first thickness region 100;

[0061] The limiting groove 42 is provided with at least one limiting hole 53 for the limiting protrusion 52 to be inserted;

[0062] When the release mechanism 5 drives the limiting protrusion 52 to disengage from the limiting hole 53, the limiting rod 41 is released from its restriction to slide along the limiting groove 42.

[0063] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting rod 41 is provided with a clearance groove 411 for moving within the limiting groove 42 and the limiting hole 53. The clearance groove 411 is the second thickness region 200, and the clearance groove 411 is located on at least one side of the first thickness region 100.

[0064] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the release mechanism 5 includes a first elastic element 54, which is used to maintain the first thickness region 100 in position with the limiting groove 42 to restrict the limiting rod 41 from sliding along the limiting groove 42.

[0065] Furthermore, as a preferred embodiment of this solution and not a limitation, the two ends of the limiting rod 41 are respectively connected to the connector bodies 2 on both sides of the seat body 1. When the unlocking mechanism 5 drives the limiting rod 41 to move, the restriction on the rotation of the connector bodies 2 on both sides relative to the seat body 1 is simultaneously released.

[0066] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the unlocking mechanism 5 includes a button 51 movably disposed on the connector body 2 and abutting against the limiting rod 41.

[0067] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a limiting member 3 disposed on the seat body 1 and corresponding to the connector body 2, wherein the two ends of the limiting rod 41 are respectively connected to the two sides of the connector body 2, and the limiting groove 42 is disposed on the limiting member 3 and allows the limiting rod 41 to pass through so as to rotate with the connector body 2.

[0068] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a prompting mechanism 7 for displaying the locked and unlocked states of the unlocking mechanism 6. The prompting mechanism 7 includes a slider 71 connected to the drive member 64. The slider 71 has a first region 72 and a second region 73. The connector body 2 has a window 74 corresponding to the first region 72 or the second region 73.

[0069] In this embodiment, a clear indication of the child safety seat's locking status is provided. The first area 72 and the second area 73 can be labeled with text or color, for example, "LOCKED" (locked) and "UNLOCKED" (unlocked), or using contrasting colors such as green and red, allowing the user to easily understand the current locking status. This design not only improves the safety and convenience of user operation but also effectively reduces safety risks caused by misoperation. When the drive unit 64 moves, the slider 71 slides accordingly, switching the area corresponding to the window 74 between the first area 72 and the second area 73. When the drive unit 64 is in the locked position, the window 74 displays the content of the first area 72, indicating to the user that the seat is locked; when the drive unit 64 is in the unlocked position, the window 74 displays the content of the second area 73, indicating to the user that the seat is not locked. This intuitive feedback mechanism ensures that the user can understand the current status of the seat promptly and accurately, avoiding operational errors caused by unclear status.
