[0023] The height-enhancing cushion is configured by cooperating with the upper base 2 and the lower base 1, so that the angle (lying angle) of the upper base can be adjusted by utilizing the relative sliding of the two, and different adjustment mechanisms can be installed respectively by utilizing the internal spaces thereof, thereby making full use of the internal spaces of the upper base 2 and the lower base 1, and rationally arranging a variety of adjustment mechanisms, so that the structure of the entire height-enhancing chair is more reasonable, the appearance is more beautiful, and the safety is also higher.

[0024] The upper base 2 uses the space at the bottom to install the locking opening and closing mechanism, which can be easily used in conjunction with the reclining angle limiting gear on the lower base 1, facilitating the reclining angle adjustment while also locking the reclining angle at a fixed angle; the upper base 2 can also use its internal space to hide the cup holder assembly 6, which not only improves the overall functionality but also improves the external aesthetics. The lower base 1 uses its internal space to install the webbing adjustment mechanism to control the extension length of the webbing assembly 3 and lock it at a certain length, making it more convenient and safer to connect the booster seat to the car seat, and also avoiding many problems caused by the exposure of the webbing adjustment mechanism.

[0025] Furthermore, the lower base 1 includes a lower base lower cover 101 and a lower base upper cover 102, that is, the lower cover and upper cover of the lower base 1, and the two are assembled together to form a lower base; similarly, the upper base 2 includes an upper base lower cover 201 and an upper base upper cover 202, that is, the lower cover and upper cover of the upper base 2, and the two are assembled together to form an upper base; the upper base lower cover 201 is slidably set on the lower base upper cover 102.

[0026] Further, combined with Figure 3 As shown, the sliding connection assembly includes a base slide groove 7 arranged on the upper cover of the lower base 1, and a slide plate 8 that can slide along the base slide groove 7 is provided at the base slide groove 7, and the slide plate 8 is connected to the lower cover of the upper base 2.

[0027] The base slide groove 7 plays a guiding and limiting role, and can connect the slide plate 8 and allow the slide plate 8 to slide along the base slide groove 7. The slide plate 8 is located in the lower base 1, and the slide plate 8 is connected to the lower cover of the upper base 2 through a connecting piece, and the connecting piece passes upward through the base slide groove 7. Through such a setting, a limit can be formed to prevent the slide plate 8 from being separated from the base slide groove 7, and the upper base 2 and the lower base 1 can also be connected, and the upper base 2 can slide relative to the lower base 1, thereby changing the angle of the upper base 2.

[0028] Further, such as Figure 5 As shown, the lying angle limiting gear comprises a lying angle gear area 9 arranged on the upper cover of the lower base 1, and a plurality of gear holes 901 are arranged in the lying angle gear area 9 at intervals along the sliding direction, and different gear holes 901 correspond to different lying angle gears; the locking opening and closing mechanism comprises a resettable buckle member 10 arranged in the upper base 2, and the buckle member 10 comprises a buckle part 1001, and a buckle lock block frame 1002 connected to the other end of the buckle part 1001, The side wall of the hand lock block frame 1002 is provided with a hand bevel groove 1003, and a base lock block 11 is provided in the hand lock block frame 1002. The side wall of the base lock block 11 is provided with a lock block guide column 1101 connected to the hand bevel groove 1003, and a lying angle lock pin 1102 used in conjunction with the lying angle limiting gear is also provided below the base lock block 11; the bottom of the hand piece 10 is also provided with a hand reset spring 12 connected to the lower cover of the upper base 2.

[0029] By pulling the hand piece 10, the base lock block 11 in the hand lock block frame 1002 at the other end can be driven to move. Due to the cooperation between the lock block guide column 1101 and the hand bevel groove 1003, the base lock block 11 will move upward while moving forward, so that the lying angle lock pin 1102 will also move upward and separate from the gear hole 901 to achieve unlocking. When the hand piece 10 is loosened, the base lock block 11 will move downward again, allowing the lying angle lock pin 1102 to be inserted into the gear hole 901 again to achieve locking. The setting of the hand reset spring 12 can automatically reset the hand piece 10.

[0030] In this embodiment, the base is divided into an upper base and a lower base, and the contact surface of the upper and lower bases is a concentric circle with an axis perpendicular to the left and right directions of the seat. A plurality of the gear holes are provided in the lower base, and a buckle for angle unlocking is provided in the upper base. The end of the buckle is connected to a base locking block, and the angle pin of the base locking block falls into the gear hole of the lower base, so that the upper and lower bases are relatively fixed; the buckle is pulled to drive the angle pin of the base locking block to disengage from the gear hole of the lower base, thereby realizing the angle unlocking of the upper and lower bases, and the upper base is pulled / pushed to slide relative to the lower base around the axis of the concentric circle, thereby realizing the adjustment of the base's lying angle.

[0031] Furthermore, a hand hole 13 is provided in front of the lower cover of the upper base 2, the hand buckle portion 1001 is arranged above the hand hole 13, and a hand buckle groove is provided on the lower cover of the upper base 2 corresponding to the hand buckle portion 1001 so that an adult's hand can buckle into the hand buckle portion.

[0032] The hand hole 13 is arranged in front of the lower cover 201 of the upper base for user convenience. This design can hide the hand buckle to prevent children from accidentally touching or playing with it. At the same time, it makes the base more comfortable to sit on and more beautiful. The upper cover of the upper base does not need to be set as a notch or protrusion left for operation.

[0033] Further, combined with Figure 6 As shown, the webbing assembly 3 includes a first webbing 301 and a second webbing 302 connected to the first webbing 301. The end of the first webbing 301 extends outward through the webbing adjustment mechanism, and the two ends of the second webbing 302 extend outward and are connected to the locking piece. By adjusting the telescopic length of the first webbing 301, the extension length of the second webbing 302 can be adjusted so that the locking piece connected to the end thereof is connected to the interface on the car.

[0034] Further, the locking member is a latch hook 4. In some embodiments, Fig.14 As shown, the locking member can also be a fix connector 26, so that it can be connected to cars of different standards.

[0035] Further, combined with Figure 7 As shown, the webbing adjustment mechanism includes a resettable button 14 arranged on the lower cover of the lower base 1, the button 14 has an internal accommodating space and a ratchet base 15 is provided in the internal accommodating space, a rotatable ratchet 17 is provided on the ratchet base 15, a locking gap is provided between the ratchet 17 and the bottom plate of the ratchet base 15, and a driving shaft 20 is provided on both sides of an end of the ratchet 17 away from the locking gap, and the driving shaft 20 is connected to the driving inclined groove 1401 on the side wall of the button 14.

[0036] The first webbing 301 can pass through the locking gap and be locked under the restriction of the ratchet 17, and can also be adjusted in telescopic length when the ratchet 17 is flipped. The ratchet 17 can be flipped relative to the ratchet base 15 to adjust the size of the locking gap. The button 14 utilizes the cooperation between the driving inclined groove 1401 thereon and the driving shaft 20 on the ratchet 17. When the button 14 is pressed and pushed, the horizontal movement of the button 14 can be converted into the flipping movement of the ratchet 17, thereby realizing the flipping control of the ratchet 17. The button 14 can also utilize its internal space to accommodate the ratchet base 15 and the ratchet 17, so that the entire webbing adjustment mechanism is more compact and reasonable, and does not occupy external space. A hand hole is also provided at the front end of the lower base to press the button.

[0037] Furthermore, base side plates 16 are provided on both sides of the ratchet base 15, and the ratchet 17 is connected to the base side plates 16 through a ratchet rotating shaft 18. A ratchet torsion spring 19 is also provided between the ratchet rotating shaft 18 and the base side plates 16, so that the ratchet 17 can automatically reset after the button 14 is released; the bottom plate of the ratchet base 15 is provided with a limiting protrusion 21 near the locking gap, which can limit the webbing and further improve the stability of the webbing locking; a button guide frame 22 is also provided on the lower cover of the lower base 1, and the button 14 is arranged at the button guide frame 22, and a button reset spring 23 is also provided between the outer periphery of the button 14 and the inner periphery of the button guide frame 22.

[0038] In this embodiment, the webbing adjustment mechanism comprises a ratchet with double holes, a ratchet base, a ratchet rotating shaft, a driving shaft, a button with a driving bevel groove, a ratchet torsion spring and a button reset spring. The ratchet can rotate around the ratchet rotating shaft on the ratchet base, and there is a ratchet torsion spring between the two. The rotating arm of the ratchet torsion spring is hung on the side wall of the ratchet base (that is, the side plate of the base). The latch webbing passes through the locking gap between the ratchet and the ratchet base and is locked by the ratchet. A driving shaft is passed through the other hole of the ratchet, and the two ends of the driving shaft pass through the left and right driving bevel grooves of the button respectively. When the button is pressed, the inclined surface of the driving bevel groove pushes the driving shaft and the ratchet to rotate and open around the ratchet rotating shaft, so that the webbing can be telescopically adjusted. When the button is released, the latch webbing is locked by the ratchet again under the action of the button reset spring and the ratchet torsion spring.

[0039] The driving grooves 1401 on both sides of the button 14 are designed as rounded triangular grooves instead of parallel grooves. The purpose of this design is: whether the driving shaft 20 of the ratchet wheel is Figure 8 The state is completely reset, or Fig. 9If the button is not fully reset, the button can be fully reset under the action of the button reset spring, thereby ensuring that the pressing surface of the button is completely in line with the contour of the lower cover of the lower base, ensuring the aesthetic appearance. Fig.10 As shown, this design can also eliminate the problem of inconsistent ratchet reset states caused by ratchet processing errors or changes in webbing material, thereby affecting the appearance.

[0040] like Fig.11 As shown, the inner arm of the button guide frame 22 is provided with a guiding and limiting structure, which not only serves as a button guide, but also can prevent the driving shaft 20 from escaping from the driving inclined groove 1401.

[0041] Further, combined with Fig.12 and Fig.13 As shown, the cup holder assembly 6 includes a drawable cup holder body 601 disposed in the upper base 2, a cup holder groove 602 is provided on the cup holder body 601, a cup holder buckle 603 is provided on the outer end of the cup holder body 601, the other end of the cup holder body 601 is connected to a cup holder fixing member 24, a cup holder guide groove 25 is provided on the lower cover of the upper base 2, and the end of the cup holder fixing member 24 is connected to the cup holder guide groove 25.

[0042] Through the above design, the cup holder body 601 can be easily pulled out from the side of the upper base 2 by pulling, and can be pushed into the upper base for storage when not in use, which is well hidden. The cup holder groove 602 is a groove with a certain depth, which can accommodate a cup; the cup holder buckle 603 is arranged on the outside, which is convenient for users to use; the cup holder guide groove 25 and the cup holder fixing member 24 are arranged in coordination, which plays a guiding and limiting role, facilitating the pulling and moving of the cup holder body 601, and can also prevent the cup holder body 601 from completely falling out of the upper base 2.

[0043] A connecting protrusion 604 is provided below the end of the cup holder body 601 located in the upper base 2 . A connecting hole 605 is provided in the connecting protrusion 604 . The connecting hole 605 is connected to the cup holder fixing member 24 . The lower end of the cup holder fixing member 24 is connected to the cup holder guiding groove 25 .

[0044] Furthermore, the cup holder assembly 6 is symmetrically arranged in two pieces, and the cup holder can be pulled out from any side, so that the child safety booster cushion can be placed on the left side, right side and middle of the vehicle seat, and the cup holder can be used. The rear of the lower base 1 is also connected to the upper pull belt 5, which can be further connected to the car seat to improve the stability and reliability of the connection installation. Example 2

[0045] The difference between this embodiment and the first embodiment is that a plug-in structure can be further provided on the base to connect the backrest, so as to form a detachable safety booster seat with adjustable lying angle.

[0046] Specifically, Figure 15 to Figure 17 As shown, the upper base 2 is provided with a snap-in groove 28 opening upward at one end away from the hand hole, and a plug-in frame 29 is provided below the backrest 27 to cooperate with the snap-in groove 28. A pair of slidable backrest connectors 30 are provided in the plug-in frame 29, and connector return springs 31 are connected to the opposite sides of the pair of backrest connectors 30. Connector limiting columns 32 are respectively provided on the opposite sides of the pair of backrest connectors 30. The connector limiting columns 32 respectively pass through the plug-in frame 29 and are connected with the connector limiting holes 33 in the snap-in groove 28. The plug-in frame 29 and the backrest connector 30 are also provided with interconnected backrest hand holes 34.

[0047] Through the connection mode of upper and lower plug-in connection, combined with the quick installation and quick release operation, the backrest 27 can be easily separated from the upper base 2. The backrest 27 can be directly lifted out of the height-enhancing cushion by pressing the backrest connector 30 in the backrest hand hole 34 with a finger, without the need to lay down the backrest 27, which is very convenient. Most of the requirements for child seats in different markets are similar, with only partial positions being different; through flexible assembly, they can be sold to different markets, such as the same backrest, with different height bases, etc., which can greatly save production management costs.
