[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1 and Figure 2As shown, the child safety seat of the present invention comprises a base 1 and a shell 2 arranged on the base 1, the base 1 is connected to the car seat, the shell 2 is provided with a seat for the child to sit on, the base 1 and the shell 2 are rotatably connected, so that the angle between the base 1 and the shell 2 can be adjusted to adjust the sitting posture of the seat, thereby improving the comfort of the child safety seat when in use. The child safety seat also includes a locking mechanism for locking the relative position of the base 1 and the shell 2 and an unlocking mechanism for driving the locking mechanism to unlock so that the angle between the base 1 and the shell 2 can be adjusted.

[0028] like Figure 3~Figure 9 As shown, the locking mechanism includes a locking member 3 slidably disposed on the left and right sides of the base 1 and a locking groove 21 disposed on the left and right sides of the housing 2 and matched with the locking member 3. When the locking mechanism is in a locked state, the locking members 3 on the left and right sides are respectively inserted into the locking groove 21 on the corresponding side; when the locking mechanism is in an unlocked state, the locking members 3 on the left and right sides are both removed from the locking groove 21 on the corresponding side. In this embodiment, the locking member 3 is a locking pin.

[0029] The unlocking mechanism includes an operating member 41 that can be slidably arranged on the left and right sides of the base 1 and a driving member 42 that can be slidably arranged on the base 1. The operating member 41 cooperates with the driving member 42, and the driving member 42 is simultaneously connected or cooperated with the locking members 3 on the left and right sides. When the operating member 41 on any side is operated to slide outward relative to the base 1, the driving member 42 is driven to slide relative to the base 1. Through the cooperation or connection between the driving member 42 and the locking member 3, the locking members 3 on the left and right sides slide relative to the base 1 until they are out of the lock groove 21, and the locking mechanism is unlocked.

[0030] In this embodiment, the operating member 41 and the locking member 3 are both slidably arranged on the base 1 along the left-right direction, and the driving member 42 is slidably arranged on the base 1 along the front-back direction. When the operating member 41 on any side is unlocked, the driving member 42 is driven to slide forward, and the locking member 3 on the same side as the operated operating member 41 slides in the opposite direction to the operating member 41, and the sliding directions of the locking members 3 on the left and right sides are opposite.

[0031] The driving member 42 is provided with two inclined surfaces 421a, and both inclined surfaces 421a are inclined from front to back toward the outside of the base 1. The operating members 41 on the left and right sides are provided with matching parts 411, and the matching parts 411 are respectively abutted against the corresponding inclined surfaces 421a. When the operating member 41 on either side is operated to slide outward relative to the base 1, the matching parts 411 provided thereon are driven to slide outwardly relative to the base 1 synchronously. In this process, the driving member 42 slides forward relative to the base 1 through the mutual abutment between the matching parts 411 and the inclined surfaces 421a.

[0032] In this embodiment, two first slide grooves 421 are provided on the driving member 42, and the length extension direction of the first slide grooves 421 is obliquely intersected with the sliding direction of the driving member 42 and the operating member 41, and the matching portion 411 is located in the first slide groove 421 and can be slidably arranged along the length extension direction of the first slide groove 421, and a side wall of the first slide groove 421 extending along its length direction is the above-mentioned inclined surface 421a matching with the matching portion 411. The matching portion 411 adopts a sliding pin.

[0033] Preferably, the two first sliding grooves 421 , namely the two inclined surfaces 421 a , are symmetrically arranged relative to the center of the base 1 .

[0034] In this embodiment, the matching portion 411 can be slidably disposed on the operating member 41 along the sliding direction of the operating member 41. In this way, when the operating member 41 on one side is operated to slide outward relative to the base 1 to unlock the locking mechanism, the operating member 41 on the other side can be fixed relative to the base 1 and remain motionless.

[0035] Specifically, the operating member 41 is provided with a second slide groove 412 extending along its sliding direction, and the matching portion 411 can be slidably arranged in the second slide groove 412 along the length extension direction of the second slide groove 412. When the locking mechanism is in a locked state, the matching portion 411 is set against an end of the second slide groove 412 close to the center of the base 1. In this way, when the locking mechanism is in a locked state, when the operating member 41 on any side is operated, such as operating the operating member 41 on the left side to make it slide outward relative to the base 1, that is, to the left, the matching portion 411 is set against the end of the second slide groove 412, thereby driving the matching portion 411 to slide to the left side of the base 1 synchronously with the operating member 41 on the left side. In this process, the driving member 42 slides forward through the matching portion 411 on the left side and the side wall of the first slide groove 421. When the driving member 42 slides forward, the matching portion 411 on the right side slides to the right in the second slide groove 412 on the operating member 41 on the right side, while the operating member 41 on the right side remains stationary.

[0036] The operating member 41 is also provided with an operating portion 413 for a person to hold when unlocking. The operating portions 413 on the left and right operating members 41 extend outward from the left and right sides of the base 1 respectively, so as to facilitate the operation of the operating member 41 when unlocking.

[0037] In this embodiment, the driving member 42 is connected to the locking members 3 on both sides via a connecting member 43. Specifically, one end of the connecting member 43 is fixedly connected to the driving member 42, and the other end of the connecting member 43 is fixedly connected to the locking member 3 on the corresponding side. The connecting member 43 is elastic.

[0038] The connecting member 43 includes a first connecting portion 431 and a second connecting portion 432 respectively located at two ends, and an intermediate connecting portion 433 connected between the first connecting portion 431 and the second connecting portion 432. The first connecting portion 431 is fixedly connected to the driving member 42, and the second connecting portion 432 is fixedly connected to the locking member 3. When the locking mechanism is in a locked state, the intermediate connecting portion 433 is arc-shaped. In the connecting member 43, at least the intermediate connecting portion 433 is elastic. In this embodiment, the connecting member 43 is made of an elastic material having elasticity as a whole.

[0039] The child safety seat further comprises an elastic member 5 for driving the driving member 42 to return to its original position after the locking mechanism is unlocked. In this embodiment, the elastic member is a spring, one end of which is arranged on the driving member 42, and the other end of which is arranged on the base 1. When the driving member 42 returns to its original position, the driving member 42 and the operating member 41 cooperate, and the driving member 42 and the locking member 3 are connected so that the operating member 41 and the locking member 3 also return to the position when the locking mechanism is in the locked state.

[0040] Of course, the driving member 42 and the locking members 3 on the left and right sides can also cooperate with each other. For example, the driving member 42 and the locking members 3 on the left and right sides are cooperated through inclined surfaces, so that when the driving member 42 slides forward relative to the base 1, the locking members 3 on the left and right sides are driven to slide and disengage from the locking groove 21.

[0041] When the child safety seat is in use, the locking mechanism is in a locked state. Figure 1 , Figure 2 , Figure 5 and Figure 6 shown.

[0042] When the sitting posture of the seat needs to be adjusted, the unlocking mechanism is operated to unlock the locking mechanism. The specific operation process is: pull the operating member 41 on either side toward the outside of the base 1, such as holding the operating portion 413 on the right operating member 41 and pulling the operating member 41 outward, the operating member 41 slides outward relative to the base 1, that is, to the right, driving the matching portion 411 provided thereon to slide to the right synchronously, and the driving member 42 slides forward through the matching of the matching portion 411 and the side wall of the first slide groove 421. When the driving member 42 slides forward, the connecting members 43 on both sides are stretched and elastically deformed, and the connecting members 43 on both sides simultaneously pull the locking members 3 connected thereto to slide toward the center of the base 1, until the locking members 3 on both sides are out of the lock groove 21, and the locking mechanism is unlocked, and the angle between the base 1 and the shell 2 can be adjusted at this time. When the driving member 42 slides forward, the matching portion 411 on the left side slides to the left in the second slide groove 412 on the left side, while the operating member 41 on the left side remains stationary. After the locking mechanism is unlocked, the matching portion 411 on the right side is still located at an end portion close to the center of the base 1 in the second slide groove 412 on the right side, while the matching portion 411 on the left side is located at an end portion away from the center of the base 1 in the second slide groove 412 on the left side. Figure 7 and Figure 8 shown.

[0043] When the angle between the base 1 and the housing 2 is adjusted to the right position, the operating member 41 is released, the force of the matching portion 411 acting on the side wall of the first slide groove 421 disappears, and the driving member 42 slides backward under the elastic force of the elastic member 5. During this process, the connecting members 43 on the left and right sides gradually recover their deformation to the initial form and drive the locking member 3 connected thereto to slide in the direction of inserting into the lock groove 21. When the driving member 42 slides backward, through the action between the side wall of the first slide groove 421 and the matching portion 411, the matching portion 411 on the right side drives the operating member 41 on the right side to slide toward the center direction of the base 1, that is, toward the left, and the matching portion 411 on the left side also slides toward the center direction of the base 1, that is, toward the right in the second slide groove 412 on the left side, until each component slides to the position when the locking mechanism is in the locked state.

[0044] The above definitions of direction are all defined according to the direction in which the child sits in the child safety seat after the child safety seat is installed forward on the car seat, with the child's face facing forward and the back facing backward.

[0045] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
