Specifically, in the present embodiment, the front end of the base 1 is provided with a front supporting leg 11, the rear end of the base 1 is provided with an ISOFIX device 12, and the ISOFIX device 12 is used for connecting with an ISOFIX interface on a car seat, so that the base 1 is more reliably fixed on the car seat by the front supporting leg 11 and the ISOFIX device 12; the carrier body 2 is a seat, but is not limited thereto.

As shown in fig. 1 to 4, and fig. 8, the carrier body 2 includes a carrier main body 21, a headrest 22, and a first misuse preventing structure 23. The carrier body 21 is selectively assembled and disassembled forwards with the base 1, and the state is shown in fig. 2 and 4; or is selectively disassembled and assembled with the base 1 in the backward direction, and the state is shown in fig. 1 and 3, so as to realize the purpose of forward use or backward use of the carrier body 2. The headrest 22 is movably disposed on the carrier body 21, so that the headrest 22 can be selectively adjusted in height relative to the carrier body 21, and the carrier body 21 has a gear for adjusting the height of the headrest 22. The first anti-misuse structure 23 is mounted on the headrest 22, preferably, as shown in fig. 8, the first anti-misuse structure 23 is fixed below the headrest 22, so as to reduce the length requirement of the first anti-misuse structure 23; and the first misuse preventing structure 23 slides up and down along with the headrest 22, and the first misuse preventing structure 23 extends to the bottom of the carrier body 21. Therefore, when the carrier main body 21 is used in the forward direction, the headrest 22 is moved away from the lowest gear, and the first anti-misuse structure 23 also resists against the base 1 to prevent the headrest 22 from being adjusted towards the lowest gear relative to the carrier main body 21, and the state is shown in fig. 2 and 4; when the carrier main body 21 is used in the backward direction, the base 1 avoids the blocking of the first misuse preventing structure 23 to allow the headrest 22 to be adjusted at will in the gear, so that the range of up-down height adjustment of the headrest 22 relative to the carrier main body 21 is indirectly limited by utilizing the cooperation between the first misuse preventing structure 23 and the base 1, and the state is shown in fig. 1 and 3. For example, in the present embodiment, referring to fig. 2, 3, 4,6 and 8, the carrier body 21 has a gear adjusting plate 211, and preferably, the gear adjusting plate 211 is disposed on the back of the carrier body 21 and is disposed in a left-right manner, so as to increase the connection stability between the headrest 22 and the carrier body 21, but not limited thereto; the gear adjusting plate 211 is provided with gear holes 2111 corresponding to different heights, and each gear hole 2111 forms a gear, that is, the gear refers to the position of the headrest 22 relative to the carrier main body 21 in height, but is not limited thereto; in order to facilitate the adjustment of the headrest 22 relative to the carrier body 21 more conveniently and flexibly, and to enable the adjusted headrest 22 to be relatively fixed, the headrest 22 is provided with a buckle 221 for selectively being locked in any gear hole 2111 or disengaged from the gear hole 2111, and the buckle 221 is fixedly arranged on the headrest 22, but is not limited thereto. More specifically, the following is:

Referring to fig. 5 to 7, in the present embodiment, a clamping rod arranged along the left-right direction of the carrier body 2 is inserted into the bottom of the carrier body 21, and a hook for selectively engaging with or disengaging from the clamping rod is provided on the base 1, wherein the clamping rod and the hook are respectively arranged in tandem along the front-rear direction of the carrier body 2. For better description below, the front-located lever is denoted by reference numeral 24a, the rear-located lever is denoted by reference numeral 24b, the front-located hook is denoted by reference numeral 13a, and the rear-located hook is denoted by reference numeral 13b; therefore, when the carrier body 21 is used in the forward direction, the clamping rod 24a is clamped with the clamping hook 13a, and the clamping rod 24b is clamped with the clamping hook 13b; when the carrier body 21 is used in the backward direction, the clamping rod 24a is clamped with the clamping hook 13b, and the clamping rod 24b is clamped with the clamping hook 13a, so that the convenience of assembling and disassembling between the carrier body 21 and the base 1 and the stability after assembling are ensured. Specifically, as shown in fig. 5, in the present embodiment, the base 1 has a front protruding structure 14 and a rear protruding structure 15 protruding outwards, each of the front protruding structure 14 and the rear protruding structure 15 has a recess 16 for accommodating the clamping rods 24a, 24b and having an open notch, the front clamping hook 13a is located on the front protruding structure 14 and selectively opens or closes the notch at the front protruding structure 14, and the rear clamping hook 13b is located on the rear protruding structure 15 and selectively opens or closes the notch at the rear protruding structure 15, so as to increase the reliability of assembly between the base 1 and the carrier body 21 by means of the front protruding structure 14 and the rear protruding structure 15, but not limited thereto; for example, as shown in fig. 5, in the present embodiment, the front bump structure 14 and the rear bump structure 15 are further arranged left to right along the left to right direction of the carrier body 2, such that a left to right front bump structure 14 and a left to right rear bump structure 15 are arranged in a quadrilateral shape on the base 1; correspondingly, the hooks 13a and 13b are also arranged left and right along the left and right directions of the carrier body 2, so that the left hook 13a is positioned on the left front protruding structure 14, the right hook 13a is positioned on the right front protruding structure 14, the left hook 13b is positioned on the left rear protruding structure 15, the right hook 13b is positioned on the right rear protruding structure 15, the clamping position of the hook 13a to the clamping rod 24a or the clamping rod 24b and the clamping position of the hook 13b to the clamping rod 24a or the clamping rod 24b are increased, the clamping stability is improved, and the supporting stability of the base 1 to the carrier body 2 is improved, but the invention is not limited thereto. It should be understood that in other embodiments, the clamping rods 24a, 24b may be disposed on the base 1, and the clamping hooks 13a, 13b are disposed on the carrier body 21 correspondingly; when the hooks 13a, 13b are disposed on the carrier body 21, the front protruding structure 14 and the rear front protruding structure 15 are correspondingly disposed on the carrier body 21, which is not limited thereto.

As shown in fig. 1 to 4 and fig. 5 to 8, the first misuse preventing structure 23 is disposed obliquely along the up-down direction (i.e., along the direction of arrow F ₂) of the carrier body 2, preferably, the first misuse preventing structure 23 is a rod-type structure and disposed in a left-right direction (i.e., along the direction of arrow F ₁) of the carrier body 2; the base 1 is provided with a clearance structure 141 for the carrier main body 21 to avoid the first misuse preventing structure 23 when being assembled on the base 1 in the backward direction, preferably, the clearance structure 141 is inclined downwards from the front to the rear of the carrier main body 2, and the clearance structure 141 is positioned on the front bulge structure 14 and is communicated with the concave groove 16 of the front bulge structure 14, so that the positions among all the components are more compact, and the purpose of saving space is achieved. In order to prevent the first misuse preventing structure 23 from blocking the clamping rod 24b when sliding to the bottom of the empty avoiding structure 141, the bottom of the first misuse preventing structure 23 is provided with a notch 231 matching the clamping rod 24b, and the first misuse preventing structure 23 slides the clamping rod 24b into the notch 231 in the process of sliding to the bottom of the empty avoiding structure 141, so that the height adjustment of the headrest 22 on the backward used carrier body 2 and the clamping between the clamping rod 24b and the clamping hook 13a are not affected. For example, in the present embodiment, the void structure 141 is a void groove, and of course, in other embodiments, the void structure 141 may be a void hole, but not limited thereto. In order to make the abutment between the base 1 and the first anti-misuse structure 23 more reliable when the carrier body 21 is assembled on the base 1 in the forward direction, the base 1 is provided with an abutment portion 151 for blocking the first anti-misuse structure 23 when the carrier body 21 is assembled on the base 1 in the forward direction, and the abutment portion 151 is located on the rear protrusion structure 15, but is not limited thereto.

The operation of the infant car vehicle 100 according to the first embodiment will be described in detail with reference to fig. 1 to 8, as follows:

When the carrier body 21 is assembled on the base 1 in a backward use manner, the clamping hook 13a on the base 1 is clamped with the clamping rod 24b on the carrier body 21, and the clamping hook 13b on the base 1 is clamped with the clamping rod 24a on the carrier body 21, so that the state is shown in fig. 1; at this time, when the headrest 22 needs to be adjusted to the lowest gear (i.e. the buckle 221 on the headrest 22 needs to be locked into the lowest gear hole 2111), the headrest 22 is adjusted to the lowest gear relative to the carrier main body 21, and the first anti-misuse structure 23 is linked to slide to the bottommost end of the avoidance structure 141; when the headrest 22 needs to be adjusted to the highest gear (namely, the buckle 221 on the headrest 22 needs to be clamped in the highest gear hole 2111), the headrest 22 is adjusted to the highest gear relative to the carrier main body 21, and the first misuse preventing structure 23 is linked to move away from the empty avoiding structure 141, so that the headrest 22 of the carrier main body 2 used in the backward direction can be adjusted at will in the gear; when the carrier body 21 is assembled on the base 1 in a forward direction, the hook 13a on the base 1 is engaged with the clamping rod 24a on the carrier body 21, and the hook 13b on the base 1 is engaged with the clamping rod 24b on the carrier body 21, as shown in fig. 2; at this time, the headrest 22 has been moved away from the lowest gear (i.e. the buckle 221 on the headrest 22 is moved away from the lowest gear hole 2111), and the first anti-misuse structure 23 abuts against the abutment portion 151 on the base 1, so as to block the headrest 22 from continuing to adjust toward the lowest gear relative to the carrier main body 21, thereby achieving the purpose of preventing the headrest 22 from being erroneously adjusted when the carrier main body 21 is assembled on the base 1 in a forward direction in use; when the headrest 22 needs to be adjusted to the highest gear, the headrest 22 is adjusted to the highest gear relative to the carrier main body 21, and the first anti-misuse structure 23 is linked to move away from the base 1. When the carrier main body 21 is assembled to the base 1 in a forward direction, if a user erroneously adjusts the headrest 22 to the lowest gear relative to the carrier main body 21, the lower end of the first anti-misuse structure 23 slides into the concave groove 16 of the rear convex structure 15, so that the hook 13b on the base 1 cannot be normally engaged with the clamping rod 24b of the carrier main body 21, thereby achieving the purpose of reminding the user of the error adjustment of the headrest 22.

Referring to fig. 9 to 13, the infant car carrier 200 of the second embodiment is basically the same as the infant car carrier 100 of the first embodiment in that the following differences are:

First, in the present embodiment, the base 1 includes a rotating base 1a and a supporting base 1b, the rotating base 1a is rotatably mounted on the supporting base 1b, so that the carrier main body 21 is selectively assembled and disassembled with the rotating base 1a in a forward direction or a backward direction, so as to facilitate the infant to take in and take out; in the first embodiment, the base 1 is a unitary structure.

In the second embodiment, the base 1 includes a rotating base 1a and a supporting base 1b, and accordingly, a front protruding structure 14, a rear protruding structure 15, a hook 13a, a hook 13b, a recess 16 and a clearance structure 141 are formed on the rotating base 1a, the front supporting leg 11 is located at the front end of the supporting base 1b, and the ISOFIX device 12 is located at the rear end of the supporting base 1 b.

Third, in the present embodiment, the base 1 further includes a limiting device (not shown) for limiting the forward and backward rotation travel of the rotating base 1a relative to the supporting base 1b, and the limiting device is disposed between the rotating base 1a and the supporting base 1 b; preferably, the limiting device limits the rotation base 1a to rotate 90 degrees (shown in fig. 10) anticlockwise and 90 degrees (shown in fig. 11) clockwise relative to the support base 1b to adjust the angles and fix the relative positions of the two, so that the infant can get on or off or take care conveniently, misuse caused by overlarge rotation angle can be prevented, and the safety performance is improved. It can be understood that the limiting device can also adjust the rotatable angle to any angle according to actual needs, and the limiting device is not limited to the above.

Referring to fig. 14 to 15, the infant car carrier 300 of the third embodiment is basically the same as the infant car carrier 200 of the second embodiment in that: in the present embodiment, the carrier body 2 is a basket; in the second embodiment, the carrier body 2 is a seat.

Third, in the present embodiment, the seat 214 has an adjustment slot 214a for adjusting the angle of the backrest 212, the backrest 212 has an adjustment rod 212a penetrating the adjustment slot 214a and sliding up and down relative to the adjustment slot 214a, and the adjustment of the relative position between the adjustment slot 214a and the adjustment rod 212a can achieve the adjustment of the backrest 212, which is simple in structure and flexible in adjustment; preferably, the adjustment lever 212a is arranged in the left-right direction of the carrier body 2, and the adjustment long hole 214a is inclined downward from the rear-to-front direction of the carrier body 2, so that the arrangement between the components is more compact, but is not limited thereto. When the carrier body 21 is used in the backward direction as shown in fig. 16 or 17, the adjusting lever 212a is moved away from the highest position of the adjusting slot 214a, and the second anti-misuse structure 213 at the limit position covers the upper portion of the adjusting slot 214a, as shown in fig. 16 and 17; when the carrier body 21 is used in the forward direction as shown in fig. 18, the second anti-misuse structure 213 at the avoiding position is retracted from shielding the upper portion of the adjustment slot 214a, and the state is shown in fig. 18. For example, the second anti-misuse structure 213 includes a blocking piece 2131 and a pushed piece 2132 fixed to the blocking piece 2131, the pushed piece 2132 is pivotally connected to the seat 214, the seat 1 pushes the pushed piece 2132 to pivot so as to enable the blocking piece 2131 to rotate for position switching, and further selectively cover the long adjustment hole 214a or withdraw from covering the long adjustment hole 214a, preferably, the blocking piece 2131 extends to an upper portion of the long adjustment hole 214a to form a covering portion 2131a, and the shape of the covering portion 2131a can be adjusted to adjust the blocking position of the blocking piece 2131 on the long adjustment hole 214a, so that the adjustment is flexible; in addition, the blocking piece 2131 is in a sheet structure and the pushed piece 2132 is in a cylindrical structure, the purpose of saving the internal space of the seat 214 can be achieved by the arrangement of the sheet structure, and the pushing of the pushed piece 2132 by the base 1 is facilitated by the cylindrical structure.

Fourth, in the present embodiment, as shown in fig. 18, the second anti-misuse structure 213 is suspended above the base 1 when the carrier main body 21 is used in the forward direction, so that the second anti-misuse structure 213 is no longer abutted against the base 1 when used in the forward direction; specifically, the base 1 has a pushing structure 142 (see fig. 17) for pushing the second misuse preventing structure 213 to rotate when the carrier main body 21 is in a backward direction, and the pushing structure 142 pushes against the pushed piece 2132 of the second misuse preventing structure 213, so as to realize position switching when the blocking piece 2131 of the second misuse preventing structure 213 rotates, so that the adjustment is flexible, but not limited thereto.

Fifth, in the present embodiment, the clamping rods 24a, 24b are located at the seat 214; in the first embodiment, the clamping bars 24a, 24b are located on the carrier body 21.

Sixth, in the present embodiment, when the carrier main body 21 is used in the backward direction, the clamping rods 24a and 24b are engaged with the clamping hooks 13a and 13b when the second anti-misuse structure 213 is at the limit position, if the backrest 212 is at the highest position of the adjustment stroke, the adjusting rod 212a slides to the highest position of the adjusting slot 214a, the blocking piece 2131 interferes with the adjusting rod 212a in the adjusting slot 214a to enable the pushed piece 2132 to be unable to be pushed by the base 1 to rotate and to be pushed by the base 1, and the pushed piece 2132 always abuts against the base 1 to enable the clamping rods 24a and 24b and the clamping hooks 13a and 13b to be unable to be engaged in place, so that the erroneous operation of the user can be reminded, thereby achieving the purpose of preventing misuse. In order to alert the operator, the carrier body 21 is further provided with an alert device 25 for alerting that the clamping bars 24a and 24b and the clamping hooks 13a and 13b are not clamped in place, and the alert device 25 can alert the user of the wrong operation by switching to the alert mark.

Seventh, in the present embodiment, the pushing structure 142 is located on the front protruding structure 14; in the first embodiment, however, it does not have the pushing structure 142.

Except for the above differences, the other differences are the same as those of the first embodiment, and thus will not be described in detail herein.

The operation principle of the infant car carrier 400 of the fourth embodiment will be described in detail with reference to fig. 16 to 18, as follows:

When the carrier main body 21 is used forward, the front hook 13a on the base 1 is engaged with the clamping rod 24a on the carrier main body 21, the rear hook 13b on the base 1 is engaged with the clamping rod 24b on the carrier main body 21, the state is shown in fig. 18, when the backrest 212 needs to be adjusted to the highest position of the adjustment stroke (i.e. the backrest 212 is in an upright state), the second misuse preventing structure 213 is suspended above the base 1, i.e. a certain distance exists between the pushed piece 2132 and the base 1, at this time, the second misuse preventing structure 213 is in an avoiding position, the adjusting rod 212a slides to the highest position of the adjustment long hole 214a, the backrest 212 performs angle adjustment towards the upright state relative to the seat 214, and random adjustment of the backrest 212 of the carrier main body 21 used forward is realized in the adjustment stroke; when the carrier body 21 is used in the backward direction, the hook 13b at the upper rear of the base 1 is engaged with the clamping rod 24a on the carrier body 21, and the hook 13a at the upper front of the base 1 is engaged with the clamping rod 24b on the carrier body 21, as shown in fig. 16 to 17; when the backrest 212 needs to be adjusted to the lowest position of the adjustment stroke (i.e. the inclination angle of the backrest 212 is the largest), at this time, the backrest 212 is moved away from the highest position of the adjustment stroke (i.e. the adjustment lever 212a is moved away from the highest position of the adjustment slot 214 a), the second anti-misuse structure 213 at the avoiding position will abut against the base 1, so that the blocking piece 2131 rotates to block the adjustment slot 214a, and the second anti-misuse structure 213 is switched from the avoiding position to the limiting position, thereby blocking the backrest 212 from performing erroneous angular adjustment toward the highest position of the adjustment stroke relative to the carrier body 21; when the carrier main body 21 is in the backward use, if the user erroneously adjusts the backrest 212 to the highest position of the adjustment stroke relative to the carrier main body 21, the adjustment rod 212a slides to the highest position of the adjustment slot 214a along with the adjustment of the backrest 212, at this time, the blocking piece 2131 interferes with the adjustment rod 212a in the adjustment slot 214a, so that the blocking piece 2131 cannot rotate to a position blocking the adjustment slot 214a, the pushed piece 2132 will always abut against the base 1, so that the front clamping rod 24a and the rear clamping hook 13b cannot be clamped in place, thereby prompting the user of the erroneous operation, and achieving the purpose of avoiding the angle of the backrest 212 from being excessively adjusted to be too upright when the carrier main body 21 is in the backward use. Since the first embodiment has already described the adjustment of the headrest 22 in detail, it will not be described here.

Compared with the prior art, since the first misuse preventing structure 23 is mounted on the headrest 22 and slides up and down along with the headrest 22, when the carrier main body 21 is used in the forward direction, the headrest 22 moves away from the lowest gear, and the first misuse preventing structure 23 also abuts against the base 1, so that the headrest 22 is prevented from being adjusted towards the lowest gear relative to the carrier main body 21; when the carrier body 21 is used in the backward direction, the base 1 avoids the resistance to the first anti-misuse structure 23 to allow the headrest 22 to be adjusted at will in the gear, so that the first anti-misuse structure 23 can prevent the defect that the headrest 22 is adjusted by mistake relative to the carrier body 21 when the carrier body 21 is selectively assembled with the base 1 in the forward direction or the backward direction, thereby ensuring that the carrier body 2 for preventing the front and the back misuse is safer to use, can be flexibly adjusted according to the use condition under the condition of avoiding the misadjustment, and achieves the aim of high flexibility. In addition, the carrier body 2 for preventing front and rear misuse has the advantage of simple structure.

It should be noted that the above-mentioned left-right direction and front-back direction are assembled on the base 1 with the carrier body 21 in a forward direction, and the user stands behind the carrier body 21 and faces forward, is left on the left side of the user, right on the right side of the user, front on the front side of the user, and rear on the rear side of the user.

The foregoing disclosure is merely illustrative of the principles of the present invention, and thus, it is intended that the scope of the invention be limited thereto and not by this disclosure, but by the claims appended hereto.
