Description

[Technical Field]

[0001] This invention belongs to the field of automotive seat technology, and particularly relates to a child car seat. [Background Technology]

[0002] Child car seats are primarily used to protect children's safety while traveling in vehicles. Currently, child car seats are increasingly widely used, and a variety of child car seats are available on the market. To make the connection between the child car seat and the car seat simpler and more secure, more and more child car seats are choosing to use ISOFIX international standardization fixing devices, which involve installing an ISOFIX support base at the bottom of the child car seat.

[0003] Children are divided into different groups according to their age. According to regulations, child car seats for different groups need to be installed forward-facing or rear-facing. This results in the need to purchase different child car seats according to the group, which increases the burden on users. At the same time, discarding a child car seat that still has a lot of life left is also wasteful. Therefore, there is a need for universal child car seats. However, existing universal child car seats need to be disassembled and installed to adjust forward or rear-facing, which is inconvenient to use. [Summary of the Invention]

[0004] The purpose of this invention is to provide a child car seat that can be adjusted to forward or backward orientation without disassembly, making it more convenient to use.

[0005] This invention is achieved by the following technical solution:

[0006] A child car seat includes an ISOFIX support base, a mounting plate rotatably mounted on the ISOFIX support base, and a car seat mounted on the mounting plate. A mounting plate adjustment and locking mechanism is provided between the ISOFIX support base and the mounting plate. The mounting plate adjustment and locking mechanism includes a mounting plate adjustment component mounted on and slidably engaged with the ISOFIX support base, a mounting plate locking component for restricting rotation of the mounting plate relative to the ISOFIX support base, and a mounting plate unlocking component. The mounting plate adjustment component is linked to the mounting plate unlocking component to release the rotation restriction on the mounting plate imposed by the mounting plate locking component.

[0007] As described above, in a child car seat, the ISOFIX support base includes an upper housing, a lower housing connected to the lower part of the upper housing, and a mounting frame disposed between the upper housing and the lower housing. The mounting plate has two opposing mounting plate adjustment slots. The mounting plate locking assembly includes a frame adjustment slot on the mounting frame, a mounting plate locking member, and a mounting plate locking spring disposed between the mounting plate locking member and the lower housing. The mounting plate locking spring is used to move the mounting plate locking member toward the mounting plate so that when the mounting plate locking member passes through both the frame adjustment slot and the mounting plate adjustment slot simultaneously, it locks the relative rotational position of the mounting plate and the mounting frame.

[0008] As described above, in a child car seat, the mounting plate unlocking assembly includes a mounting plate unlocking groove on a mounting plate adjusting member and a mounting plate unlocking pin on a mounting plate locking member. Both ends of the mounting plate unlocking pin are inserted into the mounting plate unlocking groove. The mounting plate unlocking groove cooperates with the mounting plate unlocking pin so that when the mounting plate adjusting member moves in the unlocking direction, it drives the mounting plate unlocking groove to push the mounting plate locking member out of the mounting plate adjusting groove.

[0012] The connector linkage unlocking mechanism, which is mounted on the mounting plate, is used to simultaneously unlock the locking of the front connector and the rear connector of the support base to the car seat.

[0013] As described above, in a child car seat, the front connector of the support base includes:

[0014] A front connector mounting base is provided on the mounting plate, and a front connector bayonet is provided at the end of the front connector mounting base away from the mounting plate;

[0015] A front connector hook block is hinged to one end of the front connector fixing seat near the front connector latch, and the front connector hook block is provided with a second latch.

[0016] The front connector locking spring is used to flip the front connector latch block backward so that the second latch is away from the front connector latch.

[0017] The front connector limiting pin is movably mounted on the front connector fixed seat to restrict the front connector hook block from flipping backward. The connector linkage unlocking mechanism is used to pull the front connector limiting pin to move, so as to release the restriction of the front connector limiting pin on the front connector hook block from flipping backward.

[0018] The rear connector of the support base includes:

[0019] A rear connector fixing seat is provided on the mounting plate, and a rear connector bayonet is provided at the end of the rear connector fixing seat away from the mounting plate;

[0020] A rear connector hook block is hinged to one end of the rear connector fixing seat near the rear connector latch, and the rear connector hook block is provided with a third latch.

[0021] The rear connector locking spring is used to flip the rear connector hook block forward so that the third latch is away from the rear connector latch.

[0022] The rear connector limiting pin is movably mounted on the rear connector fixing seat and is used to restrict the rear connector hook block from flipping forward. The connector linkage unlocking mechanism is used to pull the rear connector limiting pin to move, so as to release the restriction of the rear connector limiting pin on the rear connector hook block from flipping forward.

[0023] As described above, in a child car seat, the connector-linked unlocking mechanism includes:

[0024] The front connector unlocking component is movably mounted on the mounting plate, and one end is connected to the front connector limiting pin, which is used to pull the front connector limiting pin to move.

[0025] The front connector reset spring is located between the front connector unlocking component and the mounting plate, and is used to reset the front connector unlocking component;

[0026] The rear connector unlocking component is movably mounted on the mounting plate, and one end is connected to the rear connector limiting pin, which is used to pull the rear connector limiting pin to move.

[0027] The rear connector reset spring is located between the rear connector unlocking component and the mounting plate, and is used to reset the rear connector unlocking component.

[0028] The unlocking linkage is hinged to the mounting plate, with one end connected to the front connector unlocking component and the other end connected to the rear connector unlocking component.

[0029] As described above, a child car seat includes a seat body, a hidden receiving groove at the bottom of the seat body, an ISOFIX connector hinged to the hidden receiving groove and rotatably housed within the hidden 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. The connector locking component cooperates with the connector release member to restrict the rotation of the ISOFIX connector around the hinge axis. The connector unlocking component is linked with the connector release member to release the rotation restriction of the ISOFIX connector imposed by the connector locking component.

[0030] As described above, in a child car seat, 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 first locking spring causes the connector release member to rotate towards the ISOFIX connector, so that the first locking hook extends into the connector locking groove and engages with the second locking hook to lock the ISOFIX connector and restrict its rotation relative to the seat body.

[0031] As described above, in a child car seat, 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, so that the first locking hook disengages from the connector locking slot, thereby releasing the rotation restriction of the ISOFIX connector by the connector locking assembly.

[0032] As described above, in a child car seat, the ISOFIX connector includes:

Detailed Implementation Methods

[0055] 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.

[0056] Specific embodiments, such as Figure 1-13The illustrated child car seat includes an ISOFIX support base 1, a mounting plate 2 rotatably mounted on the ISOFIX support base 1, and a car seat 3 mounted on the mounting plate 2. A mounting plate adjustment and locking mechanism 7 is provided between the ISOFIX support base 1 and the mounting plate 2. The mounting plate adjustment and locking mechanism 7 includes a mounting plate adjuster 71 mounted on and slidably engaged with the ISOFIX support base 1, a mounting plate locking component 72 for restricting the rotation of the mounting plate 2 relative to the ISOFIX support base 1, and a mounting plate unlocking component 73. The mounting plate adjuster 71 and the mounting plate unlocking component 73 are linked to release the rotation restriction of the mounting plate 2 by the mounting plate locking component 72. The car seat is fixed on the mounting plate 2. The mounting plate 2 is restricted from rotating by the mounting plate locking component 72. When it is necessary to adjust the forward and reverse orientation of the car seat, the mounting plate adjusting component 71 is pulled. The mounting plate adjusting component 71 and the mounting plate unlocking component 73 work together to release the rotation restriction of the mounting plate 2 by the mounting plate locking component 72, so that the forward and reverse orientation of the car seat can be adjusted. After the angle is adjusted, the mounting plate adjusting component 71 is released, so that the mounting plate locking component 72 continues to lock the mounting plate 2. The forward and reverse orientation can be adjusted without disassembling the car seat, making it more convenient to use.

[0057] Specifically, the ISOFIX support base 1 includes an upper housing 11, a lower housing 12 connected to the lower part of the upper housing 11, and a mounting frame 13 disposed between the upper housing 11 and the lower housing 12. The mounting plate 2 is provided with two opposing mounting plate adjustment slots 22. The mounting plate locking assembly 72 includes a frame adjustment slot 721 disposed on the mounting frame 13, a mounting plate locking member 722, and a mounting plate locking spring 723 disposed between the mounting plate locking member 722 and the lower housing 12. The mounting plate locking spring 723 is used to move the mounting plate locking member 722 towards the mounting plate 2, so that when the mounting plate locking member 722 passes through the frame adjustment slot 721 and the mounting plate adjustment slot 22 at the same time, it locks the relative rotational position of the mounting plate 2 and the mounting frame 13. When the mounting plate locking member 722 passes through the frame adjustment slot 721 and the two different mounting plate adjustment slots 22 at the same time, it realizes the forward and reverse installation of the car seat respectively.

[0058] Specifically, the mounting plate unlocking assembly 73 includes a mounting plate unlocking groove 731 on the mounting plate adjusting member 71 and a mounting plate unlocking pin 732 on the mounting plate locking member 722. Both ends of the mounting plate unlocking pin 732 are respectively inserted into the mounting plate unlocking groove 731. The mounting plate unlocking groove 731 cooperates with the mounting plate unlocking pin 732 so that when the mounting plate adjusting member 71 moves in the unlocking direction, it drives the mounting plate unlocking groove 731 to push the mounting plate locking member 722 out of the mounting plate adjusting groove 22.

[0059] In addition, the mounting frame 13 is equipped with a mounting plate 2, a front connector 4 of the support base, a rear connector 5 of the support base, and a connector linkage unlocking mechanism 6. The front connector 4 of the support base is located on the mounting plate 2 and is used to lock the front end of the car seat; the rear connector 5 of the support base is located on the mounting plate 2 and is used to lock the rear end of the car seat. The front connector 4 and the rear connector 5 of the support base together lock the car seat, so that the car seat is fixed to the upper surface of the upper housing 11. The connector linkage unlocking mechanism 6 is movably located on the mounting plate 2 and is used to simultaneously unlock the locking of the car seat by the front connector 4 and the rear connector 5 of the support base. By locking the front end and the rear end of the car seat by the front connector 4 and the rear connector 5 of the support base respectively, the car seat can be firmly fixed to the upper surface of the upper housing 11. At the same time, the connector linkage unlocking mechanism 6 simultaneously unlocks the locking of the car seat by the front connector 4 and the rear connector 5 of the support base, which facilitates the installation and removal of the car seat and is simple and convenient to operate.

[0060] Further, the front connector 4 of the support base includes a front connector fixing seat 41, a front connector hook block 42, a front connector locking spring 43, and a front connector limiting pin 44. The front connector fixing seat 41 is disposed on the mounting plate 2, and a front connector slot 411 is provided at the end of the front connector fixing seat 41 away from the mounting plate 2; the front connector hook block 42 is hinged to the end of the front connector fixing seat 41 near the front connector slot 411, and a second slot 421 is provided on the front connector hook block 42; the front connector locking spring 43 is used to flip the front connector hook block 42 backward so that the second slot 421 is away from the front connector slot 411; the front connector limiting pin 44 is movably disposed on the front connector fixing seat 41 and is used to restrict the front connector hook block 42 from flipping backward; the connector linkage unlocking mechanism 6 is used to pull the front connector limiting pin 44 to move, so as to release the restriction of the front connector limiting pin 44 on the backward flipping of the front connector hook block 42. When the car seat is placed on the upper housing 11, the connecting post at the bottom of the car seat enters the front connector slot 411 and gradually pushes the front end of the front connector hook block 42, causing the front connector hook block 42 to flip forward until the second slot 421 is close to the front connector slot 411 and locks the connecting post at the bottom of the car seat. The front connector limiting pin 44 restricts the front connector hook block 42 from flipping backward, keeping the second slot 421 in a latched state. When it is necessary to remove the car seat, simply pull the front connector limiting pin 44 through the connector linkage unlocking mechanism 6 to release the restriction on the front connector hook block 42 to flip backward. Under the action of the front connector locking spring 43, the front connector hook block 42 flips backward, causing the second slot 421 to move away from the front connector slot 411, thereby releasing the second slot 421 from locking the car seat. The ISOFIX support base can be installed by simply placing the car seat on the upper housing 11 without manually locking it through the operating part, making it more convenient to use and disassemble, and easier to operate.

[0061] Specifically, the rear connector 5 of the support base includes a rear connector fixing seat 51, a rear connector hook block 52, a rear connector locking spring 53, and a rear connector limiting pin 54. The rear connector fixing seat 51 is disposed on the mounting plate 2, and a rear connector slot 511 is provided at the end of the rear connector fixing seat 51 away from the mounting plate 2; the rear connector hook block 52 is hinged to the end of the rear connector fixing seat 51 near the rear connector slot 511, and a third slot 521 is provided on the rear connector hook block 52; the rear connector locking spring 53 is used to flip the rear connector hook block 52 forward so that the third slot 521 moves away from the rear connector slot 511; the rear connector limiting pin 54 is movably disposed on the rear connector fixing seat 51 and is used to restrict the rear connector hook block 52 from flipping forward; the connector linkage unlocking mechanism 6 is used to pull the rear connector limiting pin 54 to move, so as to release the restriction of the rear connector limiting pin 54 on the forward flipping of the rear connector hook block 52. When the car seat is placed on the upper housing 11, the connecting post at the bottom of the car seat enters the rear connector latch 511 and gradually pushes the rear end of the rear connector hook block 52, causing the rear connector hook block 52 to flip backward until it approaches the third latch 521 and locks the connecting post at the bottom of the car seat. The rear connector limiting pin 54 restricts the rear connector hook block 52 from flipping forward, keeping the third latch 521 in a latched state. When it is necessary to remove the car seat, simply pull the front connector limiting pin 44 and the rear connector limiting pin 54 simultaneously through the connector linkage unlocking mechanism 6, so that the rear connector limiting pin... 54. The movement releases the restriction of the rear connector hook block 52 to flip forward. Under the action of the rear connector locking spring 53, the rear connector hook block 52 flips forward, so that the third latch 521 moves away from the rear connector latch 511, thereby releasing the locking of the third latch 521 to the car seat. The ISOFIX support base can be installed by simply placing the car seat on the upper housing 11. There is no need to manually lock it through the operating part. Moreover, the locking of the front connector 4 and the rear connector 5 of the support base to the car seat can be released simultaneously by operating the connector linkage unlocking mechanism 6. The installation and removal are more convenient and the operation is simpler.

[0062] More specifically, the connector linkage unlocking mechanism 6 includes a front connector unlocking component 61, a front connector return spring 62, a rear connector unlocking component 63, a rear connector return spring 64, and an unlocking linkage rod 65. The front connector unlocking component 61 is movably mounted on the mounting plate 2, and one end is connected to the front connector limiting pin 44, used to pull the front connector limiting pin 44 to move; the front connector return spring 62 is located between the front connector unlocking component 61 and the mounting plate 2, used to reset the front connector unlocking component 61; the rear connector unlocking component 63 is movably mounted on the mounting plate 2, and one end is connected to the rear connector limiting pin 54, used to pull the rear connector limiting pin 54 to move; the rear connector return spring 64 is located between the rear connector unlocking component 63 and the mounting plate 2, used to reset the rear connector unlocking component 63; the unlocking linkage rod 65 is hinged to the mounting plate 2, with one end connected to the front connector unlocking component 61 and the other end connected to the rear connector unlocking component 63. When the rear connector unlocking component 63 moves away from the central axis of the mounting plate 2, it pulls the rear connector limiting pin 54 away from the rear connector hook block 52, thereby releasing the restriction of the rear connector limiting pin 54 on the forward flipping of the rear connector hook block 52, and thus releasing the lock on the rear end of the car seat; at the same time, the unlocking linkage rod 65 drives the front connector unlocking component 61 to move away from the central axis of the mounting plate 2, pulling the front connector limiting pin 44 away from the front connector hook block 42, thereby releasing the restriction of the front connector limiting pin 44 on the backward flipping of the front connector hook block 42, and thus releasing the lock on the front end of the car seat; when the rear connector is released... After the head unlocking component 63 is activated, the rear connector reset spring 64 resets the rear connector unlocking component 63, thereby driving the rear connector limiting pin 54 to approach the rear connector hook block 52, thus preventing the rear connector hook block 52 from continuing to flip forward. At the same time, the front connector reset spring 62 resets the front connector unlocking component 61, thereby driving the front connector limiting pin 44 to approach the front connector hook block 42, thus preventing the front connector hook block 42 from continuing to flip backward. By operating the front connector unlocking component 61 or the rear connector unlocking component 63, the locking of the front connector 4 and the rear connector 5 of the support base to the car seat can be released simultaneously. The operation is simple and convenient.

[0063] Furthermore, the mounting plate 2 is provided with a mounting plate cover 21, which is used to restrict the front connector hook block 42 from flipping backward and the rear connector hook block 52 from flipping forward. The upper surface of the upper housing 11 is provided with a housing clearance hole 111 through which the mounting plate cover 21 passes.

[0064] Furthermore, the mounting frame 13 is hinged with a support foot 8 at its front end, and the rear end of the mounting frame 13 is provided with two opposing ISOFIX support base connectors 9. First, a rigid connection is formed with the ISOFIX interface on the vehicle through the two opposing ISOFIX support base connectors 9 at the rear end of the mounting frame 13. Then, the support of the support foot 8 at the front end forms a triangular support, doubling the resistance to tipping and reducing swaying, thus handling various road conditions. Moreover, the support foot 8 can be folded and tilted, facilitating packaging, storage, and transportation.

[0065] Specifically, the support foot 8 includes a support rod 81, a telescopic rod 82 movably disposed on the support rod 81 along the length direction of the support rod 81, and a telescopic locking mechanism 83. The telescopic locking mechanism 83 is used to lock the telescopic rod 82 to limit the movement of the telescopic rod 82 relative to the support rod 81.

[0066] More specifically, the telescopic locking mechanism 83 includes a support rod hole 831, a support rod cover 832, a gear adjustment ring 833, a gear locking pin 834, a gear adjustment hole 835, and a gear locking spring 836. The support rod hole 831 is located on the support rod 81; the support rod cover 832 is located on the support rod 81; the gear adjustment ring 833 is movably disposed within the support rod cover 832 and sleeved on the support rod 81; the gear locking pin 834 is located on the gear adjustment ring 833; the gear adjustment holes 835 are spaced apart along the length of the telescopic rod 82; the gear locking spring 836 is located between the gear adjustment ring 833 and the support rod cover 832, and is used to push the gear adjustment ring 833, thereby adjusting the gear position on the gear adjustment ring 833. The locking pin 834 remains inserted into the support rod hole 831 and the gear adjustment hole 835. When the height of the support foot 8 needs to be adjusted, the gear adjustment ring 833 is pressed to move the gear locking pin 834 away from the gear adjustment hole 835. According to different car seat heights, the telescopic rod 82 is adjusted to move relative to the telescopic rod 82 until the corresponding gear adjustment hole 835 corresponds to the support rod hole 831. The gear locking spring 836 resets, allowing the gear locking pin 834 to pass through the support rod hole 831 and the corresponding gear adjustment hole 835, completing the locking. This method is more versatile and easier to store.

[0067] The car seat 3 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 is used to cooperate with the connector release member 331 to restrict the rotation of the ISOFIX connector 32 around the hinge axis. The connector unlocking component 333 is used to work in conjunction 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.
