It is understood that, in other embodiments, the

fastening rods

24a and 24b can be disposed on the base 1, and correspondingly, the

hooks

13a and 13b are disposed on the carrier body 21; when the

hooks

13a and 13b are disposed on the carrier main body 21, the front protrusion structure 14 and the rear protrusion structure 15 are correspondingly disposed on the carrier main body 21, so the present invention is not limited thereto.

As shown in fig. 1 to 4 and fig. 5 to 8, the first anti-misuse structure 23 is along the up-down direction of the carrier body 2 (i.e., along the arrow F)₂In the direction of arrow F), preferably, the first abuse prevention structure 23 is a rod-type structure and extends in the left-right direction of the carrier body 2 (i.e., along arrow F)₁In a left-to-right arrangement); the base 1 is provided with a clearance structure 141 for the carrier main body 21 to avoid the first anti-misuse structure 23 when being assembled on the base 1 in the backward direction, preferably, the clearance structure 141 inclines downwards from the front to the rear direction of the carrier body 2, and the clearance structure 141 is positioned on the front convex structure 14 and is communicated with the concave groove 16 of the front convex structure 14, so that the positions of all the parts are more compact, and the purpose of saving space is achieved. In order to prevent the first anti-misuse structure 23 from blocking the clamping rod 24b when sliding to the bottom of the clearance structure 141, the bottom of the first anti-misuse structure 23 is provided with a notch 231 matched with the clamping rod 24b, and the clamping rod 24b slides into the notch 231 in the process that the first anti-misuse structure 23 slides to the bottom of the clearance structure 141, so that the height adjustment of the headrest 22 on the carrier body 2 used backwards and the clamping between the clamping rod 24b and the clamping hook 13a are not affected by each other. For example, in the present embodiment, the clearance structure 141 is a clearance groove, and certainly, in other embodiments, the clearance structure 141 may also be a clearance hole, but not limited thereto. In order to make the base 1 more reliable against the first anti-misuse structure 23 when the carrier body 21 is in forward use, the base 1 is provided with a carrier bodyThe body 21 blocks the abutting portion 151 of the first anti-misuse structure 23 when being assembled on the base 1 in the forward direction, and the abutting portion 151 is located on the rear protrusion structure 15, but not limited thereto.

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

when the carrier main body 21 is assembled on the base 1 in a backward use state, the hook 13a on the base 1 is engaged with the catch lever 24b on the carrier main body 21, and the hook 13b on the base 1 is engaged with the catch lever 24a on the carrier main body 21, as shown in fig. 1; at this time, when the headrest 22 needs to be adjusted to the lowest gear (that is, the buckle 221 on the headrest 22 needs to be clamped into the lowest gear hole 2111), the headrest 22 is adjusted to the lowest gear relative to the vehicle main body 21, and the first anti-misuse structure 23 is linked to slide to the lowest end of the clearance structure 141; when the headrest 22 needs to be adjusted to the highest gear (that is, the buckle 221 on the headrest 22 needs to be clamped into the highest gear hole 2111), the headrest 22 is adjusted to the highest gear relative to the vehicle main body 21, and the first anti-misuse structure 23 is linked to move away from the clearance structure 141, so that the headrest 22 of the vehicle body 2 used backwards can be adjusted freely in the gear; when the carrier main body 21 is assembled on the base 1 in a forward direction, the hook 13a on the base 1 is engaged with the catch lever 24a on the carrier main body 21, and the hook 13b on the base 1 is engaged with the catch lever 24b on the carrier main body 21, as shown in fig. 2; at this time, the headrest 22 has moved away from the lowest gear (i.e. the buckle 221 on the headrest 22 moves away from the lowest gear hole 2111), and the first anti-misuse structure 23 abuts against the abutting portion 151 on the base 1, so as to prevent the headrest 22 from being continuously adjusted to the lowest gear relative to the vehicle main body 21, thereby preventing the defect that the headrest 22 is incorrectly adjusted when the vehicle main body 21 is assembled on the base 1 in a forward 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 vehicle body 21 and is linked to the first anti-misuse structure 23 to move away from the base 1. When the carrier body 21 is assembled to the base 1 in the forward use mode, if the user mistakenly adjusts the headrest 22 to the lowest gear position relative to the carrier body 21, the lower end of the first anti-misuse structure 23 slides into the concave groove 16 of the rear protruding structure 15, so that the hook 13b on the base 1 cannot be normally engaged with the clamping rod 24b of the carrier body 21, and the purpose of reminding the user of the wrong adjustment of the headrest 22 is achieved.

Referring to fig. 9 to 13, the baby vehicle carrier 200 of the second embodiment has substantially the same structure as the baby vehicle carrier 100 of the first embodiment, except that:

When the carrier main body 21 is used in the rear direction as shown in fig. 16 or 17, the adjustment lever 212a is moved away from the highest position of the adjustment long hole 214a, and the second anti-misuse structure 213 in the limit position covers the upper portion of the adjustment long hole 214a, as shown in fig. 16 and 17; when the vehicle main body 21 is used in the forward direction as shown in fig. 18, the second anti-misuse structure 213 in the retracted position is retracted from shielding the upper portion of the adjustment long hole 214a, as shown in fig. 18. For example, the second anti-misuse structure 213 includes a blocking member 2131 and a pushed member 2132 fixed to the blocking member 2131, the pushed member 2132 is pivoted to the seat 214, the base 1 pushes the pushed member 2132 to pivot so as to make the blocking member 2131 rotate to perform position switching, and further selectively cover the adjustment long hole 214a or withdraw from covering the adjustment long hole 214a, preferably, the blocking member 2131 extends to the upper part of the adjustment long hole 214a to form a covering portion 2131a, and the blocking position of the blocking member 2131 to the adjustment long hole 214a can be adjusted by adjusting the shape of the covering portion 2131a, so that the adjustment is flexible; in addition, the blocking member 2131 is a sheet structure, and the pushed member 2132 is a cylindrical structure, the sheet structure can achieve the purpose of saving the inner space of the seat 214, and the cylindrical structure is more convenient for the base 1 to push the pushed member 2132.

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 body 21 is in forward use, so that the second anti-misuse structure 213 does not abut against the base 1 any more when in forward use; specifically, the base 1 has a pushing structure 142 (see fig. 17) for pushing against the second anti-misuse structure 213 to rotate when the carrier body 21 is used in the backward direction, and the pushing structure 142 and the pushed piece 2132 of the second anti-misuse structure 213 push against each other, so that the blocking piece 2131 of the second anti-misuse structure 213 rotates to perform position switching, and therefore, the adjustment is flexible, but not limited thereto.

Fifth, in the present embodiment, the jamming

rods

24a, 24b are located at the seat 214; in the first embodiment, the

latch rods

24a and 24b are located on the carrier body 21.

Sixth, in the present embodiment, when the carrier main body 21 is used in a backward direction, the blocking

rods

24a and 24b are engaged with the

hooks

13a and 13b when the second anti-misuse structure 213 is in the limit position, if the backrest 212 is in the highest position of the adjustment stroke, the adjustment rod 212a slides to the highest position of the adjustment slot 214a, the blocking piece 2131 interferes with the adjustment rod 212a in the adjustment slot 214a, so that the pushed piece 2132 cannot exit rotationally under the pushing action of the base 1 and abut against the base 1, and the pushed piece 2132 always abuts against the base 1, so that the blocking

rods

24a and 24b and the

hooks

13a and 13b cannot be engaged in place, thereby reminding a user of incorrect operation, and achieving the purpose of preventing misuse. In order to remind the operator, a reminding device 25 for reminding that the clamping

rods

24a and 24b and the clamping hooks 13a and 13b are not clamped in place is further arranged on the carrier main body 21, and the reminding device 25 can remind the user of wrong operation by switching to the warning mark.

Seventh, in the present embodiment, the pushing structure 142 is located on the front protruding structure 14; in the first embodiment, the pushing structure 142 is not provided.

Except for the above differences, the other parts are the same as those of the first embodiment, and therefore, the description thereof is omitted.

The operation of the infant car carrier 400 according to 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 hook 13a in front of the base 1 is engaged with the rod 24a on the carrier main body 21, and the hook 13b in back of the base 1 is engaged with the rod 24b on the carrier main body 21, as 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 anti-misuse 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 anti-misuse structure 213 is in an avoidance position, the adjustment rod 212a slides to the highest position of the adjustment slot 214a, the backrest 212 is angularly adjusted relative to the seat 214 to be upright, and the backrest 212 of the carrier main body 21 used forward is adjusted freely in the adjustment stroke; when the carrier main body 21 is used in a backward direction, the hook 13b at the back of the base 1 is engaged with the lock rod 24a on the carrier main body 21, and the hook 13a at the front of the base 1 is engaged with the lock rod 24b on the carrier main 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), and the backrest 212 is moved away from the highest position of the adjustment stroke (i.e. the adjustment rod 212a is moved away from the highest position of the adjustment long hole 214 a), the second anti-misuse prevention structure 213 in the avoidance position will abut against the base 1, so that the blocking member 2131 rotates to block the adjustment long hole 214a, and the second anti-misuse prevention structure 213 is switched from the avoidance position to the limit position, so as to block the backrest 212 from performing wrong angle adjustment to the highest position of the adjustment stroke relative to the carrier body 21; when the carrier main body 21 is used backwards, if a user mistakenly 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 the position sheltered from the adjustment slot 214a, the pushed piece 2132 always abuts against the base 1, and the clamping rod 24a in front and the clamping hook 13b in back cannot be clamped in place, so that the incorrect operation of the user is prompted, and the purpose of preventing the angle of the backrest 212 from being adjusted to be too upright when the carrier main body 21 is used backwards is achieved. Since the adjustment of the headrest 22 has been described in detail in the first embodiment, it will not be described in detail herein.

Compared with the prior art, the first anti-misuse structure 23 is arranged on the headrest 22 and slides up and down along with the headrest 22, so that when the carrier main body 21 is used in a forward direction, the headrest 22 is moved away from the lowest gear, and the first anti-misuse structure 23 is also abutted against the base 1, so that the headrest 22 is prevented from being adjusted to the lowest gear relative to the carrier main body 21; when the carrier main body 21 is used in the backward direction, the base 1 avoids the resistance of 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 main body 21 when the carrier main body 21 is selectively assembled with the base 1 in the forward direction or the backward direction, thereby ensuring safer use of the carrier main body 2 for preventing front and back misuse, and being capable of flexibly adjusting according to the use condition under the condition of avoiding wrong adjustment, thereby achieving the purpose of high flexibility. In addition, the carrier body 2 for preventing front and rear misuse of the present invention 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 facing forward, and the user stands behind the carrier body 21 and faces forward, and is left at the left side of the user, right at the right side of the user, front at the front side of the user, and back at the back side of the user.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the present invention, which is therefore intended to cover all equivalent changes and modifications within the scope of the present invention.
