Specifically, the sliding telescopic rods 31 of the ISOFIX connector 30 have at least two front and rear section portions 311 arranged along the front and rear directions of the base 10, the first locking member 40 is selectively locked with any one of the front and rear section portions 311, so as to achieve the purpose that the first locking member 40 prohibits the ISOFIX connector 30 from being adjusted forward and backward relative to the base 10, when the first locking member 40 is disengaged from being locked with the front and rear section portions 311, the first locking member 40 at this time allows the ISOFIX connector 30 to be adjusted forward and backward relative to the base 10, preferably, the first locking member 40 is located between the sliding telescopic rods 31 on the left and right sides of the ISOFIX connector 30, so as to effectively utilize the space between the sliding telescopic rods 31 on the left and right sides of the base 10. Similarly, the abutting mechanism 20 has at least two position section parts 201, and the second locking member 50 is selectively locked with any one of the position section parts 201, so as to achieve the purpose that the second locking member 50 prohibits the adjustment of the abutting mechanism 20 relative to the base 10, and when the second locking member 50 is unlocked from being locked with the position section part 201, the second locking member 50 permits the adjustment of the abutting mechanism 20 relative to the base 10; preferably, the abutting mechanism 20 is pivotally connected to the base 10 around a pivot line L, all the position segment portions 201 are located on the same arc centered on the pivot line L, so that the abutting mechanism 20 can perform forward or backward angle adjustment with respect to the base 10 around the pivot line L, and when the abutting mechanism 20 is rotated for adjustment, all the position segment portions 201 rotate centered on the pivot line L, so that each position segment portion 201 can rotate to a position opposite to the second locking member 50, so that the second locking member 50 can be locked with or unlocked from each position segment portion 201; the second locking member 50 is located in the space on the left and right sides of the abutting mechanism 20, but not limited thereto. For example, the front-back section portion 311 and the position section portion 201 are each a concave structure, and correspondingly, the first locking member 40 and the second locking member 50 each have a convex structure matching with the concave structure; of course, according to the actual requirement, the front-back section position portion 311 and the position section position portion 201 are each a convex structure, and correspondingly, the first locking member 40 and the second locking member 50 each have a concave structure matching with the convex structure; it is understood that the protruding structure may be a protruding pillar, a protruding bump or other protruding structures, and correspondingly, the recessed structure may be a slot structure, but not limited thereto. The linkage mechanism 60 comprises a lock release operation part 1 and a linkage part 2, the first locking part 40 is fixedly connected with the lock release operation part 1 to form a combined structure Z, and the linkage part 2 is connected between the second locking part 50 and the combined structure; when the release operation piece 1 is operated, the first locking piece 40 and the second locking piece 50 can simultaneously perform the release motion through the linkage piece 2. Of course, according to the needs of actual situations, the second locking member 50 is fixedly connected with the unlocking operation member 1 to form a combined structure Z, and the linkage member 2 is connected between the first locking member 40 and the combined structure Z, so that the purpose of simultaneously unlocking the first locking member 40 and the second locking member 50 through the linkage member 2 in the process of operating the unlocking operation member 1 can also be achieved, and the invention is not limited thereto. More specifically, the following:

referring to fig. 3 to 5, the first locking member 40 and the second locking member 50 are respectively disposed in a sliding manner along the left and right directions of the base 10, so that the first locking member 40 and the second locking member 50 slide along the left and right directions of the base 10 to selectively perform unlocking and locking movements; specifically, the first locking member 40 and the second locking member 50 are respectively arranged on the base 10 in a left-right manner, and the locking between the ISOFIX connector 30 and the base 10 is more stable and reliable by the first locking member 40 arranged on the left side and the right side, and similarly, the locking between the abutting mechanism 20 and the base 10 is more stable and reliable by the second locking member 50 arranged on the left side and the right side; of course, the first locking member 40 and the second locking member 50 may be disposed on the base 10 in a left or right arrangement, i.e. the first locking member 40 and the second locking member 50 are disposed on the base 10 in a single-sided arrangement, and the locking between the ISOFIX connector 30 and the base 10 and between the abutting mechanism 20 and the base 10 can also be achieved, so the invention is not limited thereto.

With reference to fig. 3 to 5, the lock releasing operation members 1 are arranged on the base 10 in a left-right arrangement, and the lock releasing operation members 1 in the same side are fixed to the first locking member 40, so that the left and right sides of the base 10 have a combined structure Z, and the user can randomly operate any one of the lock releasing operation members 1 according to the desire by the lock releasing operation members 1 at both sides, thereby improving the convenience of the child safety seat 100 a.

Referring to fig. 2 to 5, the linkage 2 includes a planar four-bar linkage 21 and a push-pull rod 22 slidably disposed along the front-rear direction of the base 10, the planar four-bar linkage 21 is pivotally connected to the assembly Z and the push-pull rod 22, and the push-pull rod 22 is linked with the second locking member 50, so that the planar four-bar linkage 21 drives the push-pull rod 22 to further drive the second locking member 50 to unlock and reset; of course, in other embodiments, the planar four-bar linkage structure 21 can be replaced by a planar five-bar linkage structure or a planar six-bar linkage structure, and therefore, the invention is not limited thereto. Preferably, each of the planar four-bar linkage 21 and the push-pull rod 22 is located in a space between the two sliding telescopic rods 31 in the ISOFIX connector 30 to reasonably utilize the internal space of the base 10, and the two opposite links 21a in the planar four-bar linkage 21 are parallel to each other to form a parallel four-bar linkage structure, so as to more effectively ensure the smoothness and reliability of the forward and backward sliding of the push-pull rod 22, but not limited thereto. Specifically, a first hinge point a in the planar four-bar linkage structure 21 is mounted on the base 10, a second hinge point b in the planar four-bar linkage structure 21, which is diagonally arranged with respect to the first hinge point a, is mounted on the push-pull rod 22, a link 21a in the planar four-bar linkage structure 21, which is used for articulating a third hinge point c, is pivotally connected to the left combined structure Z, and a link 21a in the planar four-bar linkage structure 21, which is used for articulating a fourth hinge point d, is pivotally connected to the right combined structure Z, so that the movement among the first hinge point a, the second hinge point b, the third hinge point c and the fourth hinge point d is more coordinated, and the smooth and stable forward and backward sliding of the push-pull rod 22 along the base 10 is ensured; of course, according to actual needs, the third hinge point c adjacent to the first hinge point a in the planar four-bar linkage structure 21 can be installed on the left side of the combined structure Z, and the fourth hinge point d adjacent to the first hinge point a in the planar four-bar linkage structure 21 can be installed on the right side of the combined structure Z, so that the purpose of ensuring the smoothness and stability of the sliding movement of the push-pull rod 22 along the base 10 can be achieved, and the invention is not limited thereto. For example, a first elongated section 211 extends from a front of the base 10 of a connecting rod 21a of the planar four-bar linkage 21 for hinging a third hinge point c, and the first elongated section 211 is pivoted with the left combined structure Z. Similarly, a second elongated section 212 extends from the front of the base 10 of the connecting rod 21a of the planar four-bar linkage structure 21 for hinging the fourth hinge point d, and the second elongated section 212 is pivoted with the right-side combined structure Z. Of course, the first elongated section 211 and the second elongated section 212 extend backward of the base, so the invention is not limited thereto. Specifically, the first elongated section 211 and the second elongated section 212 together form a "v" shaped structure, so that the planar four-bar linkage structure 21 utilizes space more reasonably and is more elegant, so the invention is not limited thereto. It can be understood that when the first locking member 40 and the second locking member 50 are respectively disposed on the base 10 in a single-sided arrangement, the link 21a of the planar four-bar linkage structure 21 for hinging out the third hinging point c is pivoted with the single-sided combined structure Z; of course, the third hinge point c adjacent to the first hinge point a in the planar four-bar linkage structure 21 may also be installed at the single-sided composite structure Z according to the actual requirement, so the present invention is not limited thereto.

Referring to fig. 3 to 5, an elastic member 3 is disposed between the combined structure Z and the base 10, the elastic member 3 has a tendency to drive the combined structure Z to reset, that is, after the locking operation member 1 is released, the elastic potential energy of the elastic member 3 drives the first locking member 40 formed in the combined structure Z to lock with the ISOFIX connector 30 again. The elastic part 3 is abutted between the base 10 and the first locking part 40 for forming the combined structure Z, so that the combined structure Z extrudes the elastic part 3 in the unlocking sliding process to enable the elastic part 3 to have reset elastic potential energy; of course, the elastic element 3 may also be connected between the base 10 and the first locking element 40 for forming the combined structure Z, so that the combined structure Z stretches the elastic element 3 during the lock releasing sliding process to make the elastic element 3 have the elastic potential energy for resetting, which is not limited thereto. Specifically, the base 10 is provided with a guide structure 101 for slidably guiding the first locking member 40 forming the composite structure Z, the guide structure 101 is arranged along the left-right direction of the base 10, and the first locking member 40 forming the composite structure Z is slidably disposed on the guide structure 101, so as to ensure the smoothness and stability of the left-right sliding movement of the first locking member 40 by the guide structure 101, but not limited thereto; for example, the guiding structure 101 is a guiding groove, the first locking member 40 forming the combined structure Z is fittingly disposed in the guiding groove, and the elastic member 3 is disposed in the guiding groove, so as to better utilize the space of the base 10, thereby reducing the overall volume of the base 10; of course, the guide structure 101 may also be a linear guide rod or a linear slide rail according to actual needs, and the purpose of slidably disposing the first locking member 40 on the guide structure 101 can also be achieved, so the invention is not limited thereto. More specifically, the base 10 has a socket post 102 protruding into the guiding groove for guiding the elastic element 3 to socket, so that the elastic element 3 can move more smoothly when compressed or reset, which facilitates the quick reset of the first locking element 40 and the release operation element 1, but not limited thereto.

Referring to fig. 3, 4, 6 to 8, the push-pull rod 22 has an inclined structure 221 inclined with respect to the sliding direction of the push-pull rod 22 (see the direction indicated by the double arrow P in fig. 4), the second locking element 50 linked with the push-pull rod 22 has a matching structure 501 corresponding to the inclined structure 221, the push-pull rod 22 drives the second locking element 50 linked with the push-pull rod 22 to perform a releasing motion through the inclined structure 221 and the matching structure 501, so as to realize the linkage of the push-pull rod 22 and the second locking element 50; specifically, the push-pull rod 22 is provided with an inclined long slot hole 222 inclined relative to the sliding direction of the push-pull rod 22, the inclined structure 221 is formed on the side wall of the inclined long slot hole 222, and the matching structure 501 is cooperatively disposed in the inclined long slot hole 222, so that the inclined long slot hole 222 and the matching structure 501 are cooperatively disposed in the inclined long slot hole 222, so that the push-pull rod 22 drives the second locking element 50 to perform unlocking and resetting movements in the process of sliding the push-pull rod 22 back and forth along the base 10; preferably, the inclined slot 222 is arranged in a left-right shape on the push-pull rod 22, so that the push-pull rod 22 drives the second locking member 50 to perform a locking release motion during the backward sliding process along the forward-backward direction of the base 10, and drives the second locking member 50 to perform a locking motion during the forward sliding process along the forward-backward direction of the base 10, which is not limited thereto; for example, the matching structure 501 is a column structure, such as a cylinder, but not limited thereto.

Referring to fig. 3, 4, 6 to 8, the base 10 has left and right guide rods 103 arranged along the left and right directions of the base 10, the second locking member 50 linked with the push-pull rod 22 is connected with left and right guide sliders 502, the left and right guide sliders 502 are slidably disposed on the left and right guide rods 103, and the fitting structure 501 is disposed on the left and right guide sliders 502 so as to be slidably disposed on the left and right guide rods 103 via the left and right guide sliders 502, so that during the process of the fitting structure 501 and the inclined elongated slot hole 222 moving to drive the second locking member 50 to unlock and lock, the sliding direction of the push-pull rod 22 is perpendicular to the unlocking direction of the second locking member 50, thereby ensuring the unlocking and resetting processes of the second locking member 50 to be stable and reliable, and avoiding improper unlocking or improper resetting due to deflection. Specifically, the left and right guide sliders 502 are sleeved on the left and right guide rods 103, and preferably, the left and right guide sliders 502 have U-shaped sleeve cavities 502a with upward cavities, so that the mounting and dismounting operations between the left and right guide sliders 520 and the left and right guide rods 103 are easier, and the contact area between the left and right guide sliders 502 and the left and right guide slider rods 103 can be reduced, thereby reducing the sliding friction between the left and right guide sliders 502 and the left and right guide rods 103, and facilitating the sliding of the left and right guide sliders 502. More specifically, the rear end of the push-pull rod 22 is provided with a tail plate structure 223, the inclined structure 221 is positioned on the tail plate structure 223, and the tail plate structure 223 is triangular, so that the material of the tail plate structure 223 is saved, and meanwhile, the internal space of the base 10 is more reasonably utilized; preferably, the tail plate structure 223 is connected with a hook frame 224, and the hook frame 224 is hooked on the left and right guide rods 103, so that the hook frame 224 can provide support for the sliding of the push-pull rod 22, thereby facilitating the stability of the sliding process of the push-pull rod 22.

The operation of the child safety seat 100a according to the first embodiment of the present invention will be described with reference to fig. 1 to 8: because the first locking member 40 is fixedly connected with the unlocking operation member 1 to form the combined structure Z, when a user operates the unlocking operation member 1 at any position of the left side and the right side of the base 10, the unlocking operation member 1 and the first locking member 40 slide along the left-right direction of the base 10, namely the combined structure Z slides, so that the first locking member 40 is separated from the locking with the front and rear section 311; meanwhile, the sliding of the combined structure Z drives the planar four-bar linkage structure 21 to pivot, so that the distance between the first hinge point a and the second hinge point b is increased, and the distance between the third hinge point c and the fourth hinge point d is changed, thereby causing the push-pull rod 22 at the second hinge point b to slide toward the rear of the base 10; the push-pull rod 22 sliding backwards is engaged with the engagement structure 501 through the inclined slot 222, so that the inclined structure 221 on the inclined slot 222 pulls the second locking element 50 to slide along the left and right directions of the base 10, thereby releasing the second locking element 50 from being locked with the position segment 201. Thus, the user can release the first locking member 40 and the second locking member 50 simultaneously in one locking operation, thereby allowing both the front and rear adjustment of the ISOFIX connector 30 relative to the base 10 and the front and rear tilt adjustment of the abutting mechanism 20 relative to the base 10. When the user releases the operation of the unlocking operation member 1, the elastic member 3 drives the combined structure Z to reset, so that the first locking member 40 is locked with the front and rear section 311 again; meanwhile, during the resetting process of the combined structure Z, the distance between the first hinge point a and the second hinge point b is shortened, and the distance between the third hinge point c and the fourth hinge point d is lengthened, so that the push-pull rod 22 at the second hinge point b slides towards the front of the base 10, and the push-pull rod 22 sliding towards the front cooperates with the cooperating structure 501 through the inclined slot 222, so that the inclined structure 221 on the inclined slot 222 pushes the second locking member 50 to slide along the left-right direction of the base 10, thereby locking the second locking member 50 with the position segment 201 again.
