Description

[Technical Field]

[0001] This invention belongs to the field of automotive seat technology, and particularly relates to automotive seats with concealed ISOFIX connectors. [Background Technology]

[0002] Currently, most child seats are secured by placing them on the car seat and using a shoulder strap (sometimes just a lap belt). However, different car models have different seats, seat belts, and securing methods. Differences in car seat shape, seat belt length, and anchor point location can all result in some child seats being positioned further forward or backward. All these factors make manufacturing child seats suitable for all car models a challenge, and because many people do not install child seats correctly, most child seats installed in car seats are not safe enough.

[0003] To address the aforementioned issues, the ISOFIX standard, an international standard for seat anchors, was developed. It allows for simple insertion of the ISOFIX connector on the seat into the ISOFIX connector on the car, establishing a rigid connection between the seat and the vehicle for enhanced stability. Since the ISOFIX connectors are pre-installed in the car at the factory, ISOFIX seats can be easily secured to the vehicle's ISOFIX system.

[0004] However, because the seat has ISOFIX connectors that extend a certain distance beyond the seat, it not only takes up more space and is inconvenient for packaging and transportation, but also because existing seats have ISOFIX support bases installed at the bottom of the seat to improve anti-rollover ability, reduce swaying, and cope with various road conditions. These support bases are connected and fixed to the car through ISOFIX connectors. However, because the seat has ISOFIX connectors, the ISOFIX connectors on the seat must be removed before the support base can be installed, which is very inconvenient. [Summary of the Invention]

[0005] The purpose of this invention is to provide a car seat with an ISOFIX connector that can be stored and hidden, reducing the floor space required, facilitating packaging and transportation, and making it more convenient to use.

[0006] This invention is achieved by the following technical solution:

[0007] A car seat with a concealed ISOFIX connector includes a seat body, a concealed receiving groove at the bottom of the seat body, an ISOFIX connector hinged to the concealed receiving groove and rotatably housed within the concealed receiving groove, and a connector release mechanism. The connector release mechanism includes a connector release member hinged to the seat body, a connector locking assembly, and a connector unlocking assembly. The connector locking assembly cooperates with the connector release member to restrict the rotation of the ISOFIX connector about a hinge axis. The connector unlocking assembly is linked with the connector release member to release the rotation restriction of the ISOFIX connector imposed by the connector locking assembly.

[0008] As described above, in a car seat with a concealed ISOFIX connector, the connector locking assembly includes a first locking hook on the connector release member, a connector locking groove on the upper surface of the ISOFIX connector, a second locking hook within the connector locking groove, and a first locking spring between the seat body and the connector release member. When the ISOFIX connector rotates relative to the seat body until the connector locking groove faces the seat body, the locking torsion spring causes the connector release member to rotate toward the ISOFIX connector, so that the first locking hook extends into the connector locking groove and engages with the second locking hook, locking the ISOFIX connector to restrict its rotation relative to the seat body.

[0009] As described above, in a car seat with a concealed ISOFIX connector, the connector unlocking assembly includes a connector unlocking toggle on the connector release member. By pushing the connector unlocking toggle upward, the connector release member is rotated away from the ISOFIX connector, causing the first locking hook to disengage from the connector locking slot, thereby releasing the rotation restriction of the ISOFIX connector by the connector locking assembly.

[0010] The car seat with a concealed ISOFIX connector as described above, wherein the ISOFIX connector includes:

[0011] An ISOFIX mounting bracket, one end of which is hinged to a hidden receiving groove, has a mounting bracket slot at the end of the ISOFIX mounting bracket away from the hinge axis;

[0012] The first hook block is hinged to one end of the ISOFIX mounting base near the mounting base slot, and the first hook block is provided with a first slot.

[0013] The second locking spring is used to flip the first hook block upward so that the first latch is away from the fixed base latch.

[0014] The unlocking slider is slidably mounted on the ISOFIX mounting base, and the unlocking slider is provided with a slider limiting surface for restricting the first hook block from flipping upward;

[0015] The first elastic element is disposed between the ISOFIX mounting base and the unlocking slider, and is used to slide the unlocking slider toward the first hook block;

[0016] The limiting housing is located at one end of the ISOFIX mounting base near the mounting base slot and is used to limit the first hook block from flipping upward.

[0017] As described above, in a car seat with a concealed ISOFIX connector, the inner wall of the concealed receiving groove is provided with a receiving groove positioning protrusion, and the limiting outer shell is provided with an outer shell positioning hole corresponding to the receiving groove positioning protrusion. When the ISOFIX connector is rotated and stored in the concealed receiving groove, the receiving groove positioning protrusion enters the outer shell positioning hole.

[0018] As described above, the car seat with a concealed ISOFIX connector has a headrest that slides with it and a headrest adjustment and locking mechanism. The headrest adjustment and locking mechanism includes a headrest adjuster disposed on the headrest and slidingly engaged with it, a headrest locking component for restricting the movement of the headrest relative to the seat body, and a headrest unlocking component. The headrest adjuster and the headrest unlocking component are linked to release the headrest locking component from restricting the movement of the headrest.

[0019] As described above, the car seat with a concealed ISOFIX connector has a plurality of headrest adjustment slots on the seat body arranged along the sliding direction of the headrest relative to the seat body. The headrest locking assembly includes a headrest limiting slot, a headrest locking rod, and a headrest locking tension spring between the headrest unlocking assembly and the headrest. The headrest locking tension spring is used to pull the headrest locking rod towards the headrest so that when the headrest locking rod is simultaneously engaged with the headrest adjustment slot and the headrest limiting slot, the relative position of the headrest and the seat body is locked.

[0020] As described above, in a car seat with a concealed ISOFIX connector, the headrest unlocking assembly includes a headrest unlocking member disposed on the headrest, a headrest locking lever disposed on the headrest unlocking member, and a headrest locking spring for rotating the headrest unlocking member to move the headrest locking lever toward the headrest. The headrest unlocking member cooperates with the headrest adjusting member so that when the headrest adjusting member moves toward the unlocking direction, it drives the headrest unlocking member to rotate, thereby driving the headrest locking lever toward the direction away from the headrest adjusting groove.

[0021] As described above, the car seat with a concealed ISOFIX connector has a seat base at the bottom of the seat body that slides with it, and a seat adjustment locking mechanism. The seat base has an arc-shaped adjustment hole, and a seat adjustment rod passing through the arc-shaped adjustment hole is provided on the seat base. The seat adjustment rod slides in the arc-shaped adjustment hole to make the seat body slide relative to the seat base, and the seat adjustment locking mechanism restricts the sliding of the seat body relative to the seat base.

[0022] As described above, in a car seat with a concealed ISOFIX connector, the seat adjustment locking mechanism includes:

[0023] Locking adjustment holes are located on both sides of the seat base along the arc direction of the arc-shaped adjustment hole.

[0024] The locking adjustment seat is located on the seat body;

[0025] A locking adjusting pin is movably mounted on the locking adjusting seat in a direction that is close to or away from the locking adjusting hole;

[0026] A locking adjustment handle is movably mounted on a locking adjustment seat along the direction of approaching or moving away from the locking adjustment pin. The locking adjustment handle is provided with a seat adjustment groove, and one end of the locking adjustment pin is movably mounted in the seat adjustment groove.

[0027] A locking adjustment spring is located between the locking adjustment seat and the locking adjustment handle, and is used to push the locking adjustment handle to move closer to the locking adjustment pin;

[0028] The locking adjustment spring pushes the locking adjustment handle to move closer to the locking adjustment pin, causing the seat adjustment groove wall on the locking adjustment handle to push the locking adjustment pin closer to the locking adjustment hole and insert it into the locking adjustment hole, thereby restricting the sliding of the seat body relative to the seat base.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] This invention provides a car seat with a concealed ISOFIX connector, including a seat body, a concealed receiving groove at the bottom of the seat body, an ISOFIX connector hinged to the concealed receiving groove and rotatably stored within the concealed receiving groove, and a connector release mechanism. The connector release mechanism includes a connector release member hinged to the seat body, a connector locking component, and a connector unlocking component. In use, after the ISOFIX connector rotates out of the concealed receiving groove, it is fixed by the connector locking component, allowing the car seat to be directly installed in the car. When the car seat is removed from the car and is no longer in use, the connector unlocking component releases the rotation restriction of the ISOFIX connector by the connector locking component, allowing the ISOFIX connector to rotate and be stored in the concealed receiving groove. This not only reduces the floor space and facilitates packaging and transportation, but also allows the car seat's ISOFIX connector to be stored and directly installed on the ISOFIX support base when an ISOFIX support base is needed, without the need to remove the car seat's ISOFIX connector, making it more convenient to use.

Detailed Implementation Methods

[0039] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention 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 the invention and are not intended to limit the invention.

[0040] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of the present invention, unless they actually express the meaning of order according to the context, they should be understood as being used only for differentiation.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Specific embodiments, such as Figure 1-7 The car seat shown includes a seat body 31, a hidden receiving groove 34 located at the bottom of the seat body 31, an ISOFIX connector 32 hinged to the hidden receiving groove 34 and rotatably housed within the hidden receiving groove 34, and a connector release mechanism 33. The connector release mechanism 33 includes a connector release member 331 hinged to the seat body 31, a connector locking component 332, and a connector unlocking component 333. The connector locking component 332 cooperates with the connector release member 331 to restrict the rotation of the ISOFIX connector 32 about the hinge axis. The connector unlocking component 333 is linked with the connector release member 331 to release the rotation restriction of the ISOFIX connector 32 imposed by the connector locking component 332. When in use, the ISOFIX connector rotates out of the hidden receiving slot and is secured by the connector locking component, allowing the car seat to be directly installed on the car. When the car seat is removed from the car and is no longer in use, the connector unlocking component releases the rotation restriction of the ISOFIX connector, allowing the ISOFIX connector to rotate and be stored in the hidden receiving slot. This not only reduces the footprint and facilitates packaging and transportation, but also allows the car seat's ISOFIX connector to be stored and directly installed on the ISOFIX support base when needed, without the need to remove the car seat's ISOFIX connector, making it more convenient to use.

[0043] Specifically, the connector locking assembly 332 includes a first locking hook 3321 disposed on the connector release member 331, a connector locking groove 3322 disposed on the upper surface of the ISOFIX connector 32, a second locking hook 3323 disposed within the connector locking groove 3322, and a first locking spring 3324 disposed between the seat body 31 and the connector release member 331. When the ISOFIX connector 32 rotates relative to the seat body 31 until the connector locking groove 3322 faces the seat body 31, the first locking spring 3324 causes the connector release member 331 to rotate closer to the ISOFIX connector 32, so that the first locking hook 3321 extends into the connector locking groove 3322 and engages with the second locking hook 3323 to lock the ISOFIX connector 32 and restrict its rotation relative to the seat body 31. It is convenient to use.

[0044] More specifically, the connector unlocking assembly 333 includes a connector unlocking toggle 3331 disposed on the connector release member 331. By pushing the connector unlocking toggle 3331 upward, the connector release member 331 is rotated away from the ISOFIX connector 32, causing the first locking hook 3321 to disengage from the connector locking slot 3322, thereby releasing the rotation restriction of the ISOFIX connector 32 by the connector locking assembly 332. This provides ease of use.

[0045] Additionally, the ISOFIX connector 32 includes an ISOFIX mounting base 321, a first latch block 322, a second locking spring 323, an unlocking slider 324, a first elastic element 325, and a limiting housing 326. One end of the ISOFIX mounting base 321 is hinged to a hidden receiving groove 34, and the end of the ISOFIX mounting base 321 away from the hinge axis has a mounting base slot 3211; the first latch block 322 is hinged to the end of the ISOFIX mounting base 321 near the mounting base slot 3211, and the first latch block 322 has a first slot 3221; the second locking spring 323 is used to flip the first latch block 322 upwards, so that the first slot 3221 moves away from the mounting base slot 3211; the unlocking slider 324... Block 324 is slidably disposed on ISOFIX mounting base 321. The unlocking slider 324 is provided with a slider limiting surface 3241 for limiting the upward flipping of the first hook block 322. The first elastic element 325 is disposed between ISOFIX mounting base 321 and unlocking slider 324 for causing unlocking slider 324 to slide towards the first hook block 322. The limiting housing 326 is disposed at one end of ISOFIX mounting base 321 near the mounting base slot 3211 for limiting the upward flipping of the first hook block 322.

[0046] When the ISOFIX connector 32 is inserted into the automotive ISOFIX interface, the automotive ISOFIX interface pushes the lower part of the first hook block 322, causing the first hook block 322 to flip downwards until the first slot 3221 of the first hook block 322 corresponds to the slot 3211 of the fixing seat to be locked in the automotive ISOFIX interface. At the same time as the first hook block 322 flips downwards, the first elastic element 325 pushes the unlocking slider 324 to bring the unlocking slider 324 closer to the first hook block 322 until the slider limiting surface 3241 is located below the first hook block 322 to restrict the first hook block 322 from flipping upwards, so that the first slot 3221 of the first hook block 322 remains locked in the automotive ISOFIX interface.

[0047] When the unlock button is pushed, causing the unlock slider 324 to move away from the first hook block 322, the restriction of the slider limiting surface 3241 on the first hook block 322 is released. Under the action of the second locking spring 323, the first hook block 322 flips upward to release the latch connection with the car ISOFIX interface until it flips to the limiting housing 326 to restrict the first hook block 322 from flipping upward.

[0048] Furthermore, the inner wall of the concealed receiving groove 34 is provided with a receiving groove positioning protrusion 341, and the limiting outer shell 326 is provided with an outer shell positioning hole 3261 corresponding to the receiving groove positioning protrusion 341. When the ISOFIX connector 32 is rotated and housed in the concealed receiving groove 34, the receiving groove positioning protrusion 341 enters the outer shell positioning hole 3261. The ISOFIX connector 32 is fixed in the concealed receiving groove 34, preventing the ISOFIX connector 32 from falling out of the concealed receiving groove 34 due to gravity.

[0049] Specifically, the seat body 31 is provided with a headrest 35 that slides with it, and a headrest adjustment and locking mechanism 36. The headrest adjustment and locking mechanism 36 includes a headrest adjuster 361 disposed on the headrest 35 and slidingly engaged with it, a headrest locking component 362 for restricting the movement of the headrest 35 relative to the seat body 31, and a headrest unlocking component 363. The headrest adjuster 361 and the headrest unlocking component 363 are linked to release the movement restriction of the headrest 35 by the headrest locking component 362. By using the headrest unlocking component 363 to allow the headrest 35 to move relative to the seat body 31, and then using the headrest locking component 362 to restrict the movement of the headrest 35 relative to the seat body 31, the position of the headrest 35 is fixed, thereby achieving the effect of adjusting the headrest height, which can accommodate children of different heights and provide support for children's heads.

[0050] More specifically, the seat body 31 is provided with a plurality of headrest adjustment grooves 311 arranged along the sliding direction of the headrest 35 relative to the seat body 31. The headrest locking assembly 362 includes a headrest limiting groove 3621, a headrest locking rod 3622, and a headrest locking tension spring 3623 disposed between the headrest unlocking assembly 363 and the headrest 35. The headrest locking tension spring 3623 is used to pull the headrest locking rod 3622 toward the headrest 35 so that when the headrest locking rod 3622 is simultaneously inserted into the headrest adjustment groove 311 and the headrest limiting groove 3621, the relative position of the headrest 35 and the seat body 31 is locked.

[0051] Furthermore, the headrest unlocking assembly 363 includes a headrest unlocking member 3631 disposed on the headrest 35, a headrest locking rod 3622 disposed on the headrest unlocking member 3631, and a headrest locking spring 3623 used to rotate the headrest unlocking member 3631 to drive the headrest locking rod 3622 to move closer to the headrest 35. The headrest unlocking member 3631 cooperates with the headrest adjusting member 361 so that when moving in the unlocking direction through the headrest adjusting member 361, it drives the headrest unlocking member 3631 to rotate to drive the headrest locking rod 3622 to move away from the headrest adjusting groove 311. When the headrest adjustment component 361 pulls up one end of the headrest unlocking component 3631, it can move the end of the headrest unlocking component 3631 connected to the headrest locking rod 3622 outward away from the headrest 35, thereby moving the headrest locking rod 3622 away from the headrest adjustment groove 311 and the headrest limiting groove 3621.

[0052] Furthermore, the bottom of the seat body 31 is provided with a seat base 312 that slides with it, and a seat adjustment and locking mechanism 10. The seat base 312 has an arc-shaped adjustment hole 3121, and a seat adjustment rod 313 passing through the arc-shaped adjustment hole 3121. The seat adjustment rod 313 slides in the arc-shaped adjustment hole 3121 to allow the seat body 31 to slide relative to the seat base 312, and the seat adjustment and locking mechanism 10 restricts the sliding of the seat body 31 relative to the seat base 312. The seat body 31 slides relative to the seat base 312 to adjust the angle of the seat body 31, and then is locked by the seat adjustment and locking mechanism 10, improving the child's riding comfort.

[0053] Specifically, the seat adjustment locking mechanism 10 includes a locking adjustment hole 101, a locking adjustment seat 102, a locking adjustment pin 103, a locking adjustment handle 104, and a locking adjustment spring 105. The locking adjustment hole 101 is located on both sides of the seat base 312 along the arc of the arc-shaped adjustment hole 3121; the locking adjustment seat 102 is located on the seat body 31; the locking adjustment pin 103 is movably disposed on the locking adjustment seat 102 along the direction of approaching or moving away from the locking adjustment hole 101; the locking adjustment handle 104 is movably disposed on the locking adjustment seat 102 along the direction of approaching or moving away from the locking adjustment pin 103, and the locking adjustment handle 104 is provided with a seat adjustment groove 1041, with one end of the locking adjustment pin 103 movably disposed in the seat adjustment groove 1041. The locking adjustment spring 105 is located between the locking adjustment seat 102 and the locking adjustment handle 104, and is used to push the locking adjustment handle 104 to move closer to the locking adjustment pin 103. The locking adjustment spring 105 pushes the locking adjustment handle 104 to move closer to the locking adjustment pin 103, so that the groove wall of the seat adjustment groove 1041 on the locking adjustment handle 104 pushes the locking adjustment pin 103 to move closer to the locking adjustment hole 101 and insert it into the locking adjustment hole 101, so as to limit the sliding of the seat body 31 relative to the seat base 312. During adjustment, pull the locking adjustment handle 104 away from the locking adjustment pin 103. The groove wall of the seat adjustment groove 1041 on the locking adjustment handle 104 pushes the locking adjustment pin 103 away from the locking adjustment hole 101 until it disengages from the locking adjustment hole 101, allowing the seat body 31 to slide relative to the seat base 312. After releasing the locking adjustment handle 104, the locking adjustment pin 103 is reinserted into the corresponding locking adjustment hole 101 to complete the angle adjustment of the seat body 31. The angle adjustment operation is very convenient and quick, making it easy for users to use in daily life, and also greatly improving the riding comfort of children.
