[0129] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure and its application or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully express the scope of the present disclosure to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of the components and steps, the composition of the materials, the numerical expressions and the numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary and not as limiting.

[0130] The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different parts. The words "include" or "comprise" and similar words mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of including other elements. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0131] In the present disclosure, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0132] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0133] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0134] Reducing the damage to children from strong collision kinetic energy when riding in a high-speed motor vehicle is the primary design factor to be considered in the child carrier in car seat mode. Relatively speaking, comfort becomes a secondary option. Therefore, the angle between the seat plate and the backrest of the child car seat in the related art is a fixed angle.

[0135] If the angle between the seat and backrest of the car seat is set to be greater than 100 degrees, the child will easily slide out from the backrest when the car seat is hit from the front, thus causing serious injuries. Therefore, in order to provide a sufficiently strong protection for children when the car seat is subjected to a high-speed collision, the angle between the seat and backrest of the car seat is usually set between 95 degrees and 100 degrees, and is usually an integrated fixed angle shape, and a five-point safety belt is also added to restrain the child member between the seat and backrest, so as to form a strong safety protection effect that is sufficient to protect the child member when subjected to external force collision.

[0136] However, after the car seat mode is switched to the child stroller mode, the speed of the child stroller is low, and the safety belt is used properly during the pushing process, so the risk of the child sliding out from the backrest and getting injured is low. The angle between the seat plate and the horizontal line is usually about 10 degrees, and the angle between the backrest and the horizontal line is adjustable between 95 degrees and 180 degrees. Under the premise of ensuring low-speed travel safety, the comfort of the child members can be increased as much as possible. Especially for younger children, it is more comfortable to adjust the angle between the backrest and the seat plate to more than 110 degrees.

[0137] Users require that pushable car seats have sufficient safety protection against high-speed collisions, as well as sufficient comfort in the push mode. If the car seat's backrest or seat plate is simply configured to be rotatable to open and close, there will be a risk of misuse by the user. That is, in the car seat mode, the user may forget or be unable to skillfully adjust the angle between the seat plate and the backrest to a safe angle for use, which will increase the possibility of injury from misuse.

[0138] In view of this, in one aspect of an embodiment of the present disclosure, a child carrier is provided, which can improve the safety of use.

[0139] Figure 1 is a structural exploded view of some embodiments of the child carrier disclosed herein, with reference to Figure 1 The child carrier includes: a carrier body, a walking mechanism 3 and an anti-fool mechanism 4.

[0140] The vehicle body comprises a back plate assembly 1 and a seat plate assembly 2 with adjustable relative angles. A walking mechanism 3 is connected to the vehicle body and can be unfolded or folded relative to the vehicle body. An anti-fool mechanism 4 is connected to the back plate assembly 1 and / or the seat plate assembly 2.

[0141] The child carrier is in stroller mode by unfolding the walking mechanism 3, and in baby car seat mode by folding the walking mechanism 3. The anti-fool mechanism 4 is configured to adjust the angle between the back panel assembly 1 and the seat panel assembly 2 to a preset safety angle in the baby car seat mode. In stroller mode, the user can adjust the angle between the seat panel assembly 2 and the back panel assembly 1 to meet the needs of the child sitting or lying. The preset safety angle can be set according to factors such as industry, national or international safety standards, actual application scenarios, etc., for example, 95 degrees to 100 degrees.

[0142] In this embodiment, by providing the anti-mistake mechanism 4, the angle between the back panel assembly 1 and the seat panel assembly 2 can be set to a preset safety angle in the car mode, so as to reduce the safety hazard to the child caused by the user not adjusting the child carrier to a safe angle when using the child carrier in the car, which helps to improve the reliability and convenience of the child carrier.

[0146] In the present embodiment, the anti-mistake mechanism 4 acts on the seat plate assembly 2 and / or the back plate assembly 1. During the process of the walking mechanism 3 being folded toward the carrier body, the anti-mistake mechanism 4 can push the angle between the seat plate assembly 2 and the back plate assembly 1 to gradually adjust to a preset safety angle, so that when the child carrier is switched to the car seat mode, the angle between the seat plate assembly 2 and the back plate assembly 1 is automatically switched to a preset safety angle, eliminating the operational requirement for the user to adjust the angle, reducing the risk of misuse, and improving the safety of the child carrier.
