[0034] It should be noted that, without conflict, the features in the embodiments of the present utility model may be combined with each other.

[0035] As described in the background art, during the use of a child safety seat, a toddler usually sits backwards relative to the car seat, and when sitting backwards, due to the limitation of the car seat backrest, the seating space is limited, thereby resulting in relatively low seating comfort for the toddler.

[0036] Please refer to Figure 1 and Figure 2 , the translatable safety seat 100 and the child safety seat provided in the embodiments of the present utility model can solve the above problems, and will be described in detail hereinafter.

[0037] The translatable safety seat 100 includes a base 110, a support plate 120, and a backrest assembly 130 which are arranged in sequence from bottom to top;

[0038] Wherein, the support plate 120 is provided with a first sliding part 121, and the backrest assembly 130 or the base 110 is provided with a second sliding part 150, and the first sliding part 121 and the second sliding part 150 are slidably matched in the front-rear direction.

[0039] During the working process, when a child needs to sit in reverse, the relative sliding of the first sliding part 121 and the second sliding part 150 in the front-back direction can drive the backrest assembly 130 to move away from the car seat backrest, so as to increase the reverse sitting space and improve the riding comfort of the child.

[0040] It should be noted that when a child is sitting in a safety seat, when the child is relatively young (usually under 4 years old), the safety seat will be reversed relative to the forward direction of the vehicle body so that the child can sit in reverse to improve the protection of young children. And the front-back direction refers to the forward and backward directions of the car, which can also be understood as the front and back of the car seat.

[0041] Moreover, in order to facilitate driving the backrest assembly 130 to rotate and change direction, the support disc 120 can be rotationally matched with the base 110. Under the action of an external force, the support disc 120 rotates relative to the base 110, thereby driving the backrest assembly 130 to rotate synchronously.

[0042] Reference Figure 1 , in order to improve the disassembly and assembly convenience, the backrest assembly 130 can include a fixed bracket 132 and a support backrest 133 that are detachably connected. The second sliding part 150 is arranged on the fixed bracket 132, and the first sliding part 121 is located on the top side of the support disc 120.

[0043] When one of the fixed bracket 132 or the support backrest 133 is damaged, only the damaged one can be disassembled and replaced, while the other can continue to be used, which can improve the disassembly and assembly convenience of the backrest assembly 130 and reduce the maintenance and replacement costs at the same time.

[0044] In this embodiment, an installation groove 1331 is formed at the bottom of the support backrest 133. The fixed bracket 132 is accommodated in the installation groove 1331 and connected to the side wall of the installation groove 1331. On the one hand, it can prevent the installation bracket from protruding outside the support backrest 133, thereby improving the aesthetics of the backrest assembly 130; on the other hand, the cooperation between the fixed bracket 132 and the installation groove 1331 can improve the connection strength between the fixed bracket 132 and the support backrest 133 and prevent the two from separating easily.

[0045] Specifically, threaded holes are provided on the side walls of both the fixed bracket 132 and the installation groove 1331 of the support backrest 133, and the corresponding threaded holes are connected by bolts; of course, in other embodiments of the present invention, the side walls between the fixed bracket 132 and the installation groove 1331 of the support backrest 133 can also be snap-connected or pin-connected, and the detachable connection method is not limited.

[0046] Reference Figure 1 and Figure 3The first sliding portion 121 includes two first sliding rails 1211, which are respectively formed on both sides of the limiting groove 122; the second sliding portion 150 includes two second sliding rails 151, which are respectively formed on both sides of the bottom of the fixed bracket 132, and the second sliding rails 151 are slidably matched with the first sliding rails 1211.

[0047] Furthermore, the first slide rail 1211 is buckled onto the upper side of the second slide rail 151. Even if the second slide rail 151 is subjected to a certain external force, the second slide rail 151 cannot be easily separated from the first slide rail 1211, thereby ensuring the sliding stability of the two slide rails and preventing derailment.

[0048] It is worth noting that the second slide rail 151 usually only slides out from the front end of the first slide rail 1211, and does not slide out from the rear end of the first slide rail 1211, so as to avoid the seat back assembly 130 from colliding with the car seat back, so that a limit block 123 can be formed on the support plate 120, and the limit block 123 is arranged at the rear end of the first sliding part 121. Specifically, the limit block 123 is arranged at the rear end of the first slide rail 1211.

[0049] When the seat back assembly 130 is subjected to an external force moving toward the car seat back, the limit block 123 can resist and block the second slide rail 151 to prevent the second slide rail 151 from moving out from the rear end of the first slide rail 1211, thereby preventing the distance between the seat back assembly 130 and the car seat back from decreasing, thereby avoiding further reducing the seating space for young children.

[0050] refer to Figure 1 and Figure 3 In order to ensure that the fixing bracket 132 can translate forward and backward relative to the supporting plate 120 and avoid relative deflection in the left and right directions, the supporting plate 120 can be provided with a limiting groove 122, and the bottom of the fixing bracket 132 is accommodated in the limiting groove 122, and the limiting groove 122 extends along the front and rear directions.

[0051] In addition, in order to prevent the support plate 120 from easily separating from the base 110 during rotation, a rotation hole 124 can be set at the center of the support plate 120, and a rotation pillar 111 that cooperates with the rotation hole 124 is formed on the base 110. The rotation pillar 111 passes through the rotation hole 124, so that the support plate 120 is centered on the rotation pillar 111 during rotation.

[0052] refer to Figure 1 and Figure 4, From the perspective of improving the convenience of front - rear translation, the safety seat 100 that can be translated front - rear further includes a translation driving member 140. The translation driving member 140 is connected to both the support disk 120 and the backrest assembly 130, and is used to drive the backrest assembly 130 to slide relative to the support disk 120, so as to drive the backrest assembly 130 to approach or move away from the car seat backrest.

[0053] Moreover, the translation driving member 140 includes a connected driving power source 141 and a driving telescopic rod 142. The driving power source 141 is installed on the support disk 120, and the driving telescopic rod 142 is connected between the driving power source 141 and the backrest assembly 130. Specifically, one end of the driving telescopic rod 142 away from the driving power source 141 is connected to the fixed bracket 132.

[0054] Meanwhile, an adjustment switch can be set on the fixed bracket 132 or the support backrest 133. The adjustment switch is used to communicate with the driving power source 141, and the user can control the working state of the driving power source 141 by pressing or turning the adjustment switch.

[0055] During the working process, the driving power source 141 is used to provide power to drive the driving telescopic rod 142 to extend or shorten. When the driving telescopic rod 142 extends, it can drive the fixed bracket 132 to translate forward relative to the support disk 120 in the direction of the car's travel, so as to increase the distance between the support backrest 133 and the car seat backrest. When the driving telescopic rod 142 shortens, it can drive the fixed bracket 132 to translate backward relative to the support disk 120 in the direction of the car's travel, so as to reduce the distance between the support backrest 133 and the car seat backrest. During the translation process, the support backrest 133 moves synchronously with the fixed bracket 132. At this time, the first slide rail 1211 and the second slide rail 151 play a role in moving guidance to ensure the translation stability of the backrest assembly 130.

[0056] It should be noted that the driving power source 141 can specifically be a linear motor, a linear cylinder or a linear hydraulic cylinder, and its specific power form is not limited.

[0057] Reference Figure 4 , The fixed bracket 132 is provided with an extension hole 1321. The extension hole 1321 is in a long - strip shape. The driving power source 141 is accommodated in the extension hole 1321, and the driving telescopic rod 142 is located above the extension hole 1321.

[0058] When the driving power source 141 and the driving telescopic rod 142 pull the fixed bracket 132 to translate back and forth relative to the support disk 120, the driving power source 141 can move relatively from one end of the extension hole 1321 to the other end, and the telescopic direction of the driving telescopic rod 142 is consistent with the long - strip extension direction of the extension hole 1321, which can further improve the stability of the front - rear translation movement.

[0059] Reference Figure 5 Moreover, the second sliding part 150 can be arranged on the base 110, and the second sliding part 150 is in a long groove shape, while the first sliding part 121 is located at the bottom side of the support disk 120 and is in a slider shape, so as to facilitate the first sliding part 121 to slide along the second sliding part 150 in the front-rear direction, so as to drive the backrest assembly 130 to perform front-rear translation.

[0060] Meanwhile, in order to facilitate driving the support backrest 133 to rotate and change direction, the fixing bracket 132 can be provided with a rotating recess 1322, the support disk 120 is received in the rotating recess 1322, and the fixing bracket 132 is rotationally matched with the support disk 120. When an external force acts on the support backrest 133, the fixing bracket 132 can be driven to rotate relative to the support disk 120.

[0061] Moreover, the rotating recess 1322 can specifically be a circular groove or a circular hole, and no limitation is made on its specific structural type.

[0062] In summary, the safety seat 100 capable of front-rear translation provided by the embodiment of the present invention has at least the following advantages:

[0063] (1) The safety seat 100 capable of front-rear translation drives the backrest assembly 130 to move away from the backrest of the vehicle seat in the front-rear direction through the relative sliding of the first sliding part 121 and the second sliding part 150 in the front-rear direction, so as to increase the reclining space, thereby improving the riding comfort of the infant.

[0064] (2) The safety seat 100 capable of front-rear translation is provided with a translation driving member 140. The translation driving member 140 is connected to both the support disk 120 and the backrest assembly 130 at the same time, and is used to drive the backrest assembly 130 to slide relative to the support disk 120, so as to drive the backrest assembly 130 to approach or move away from the backrest of the vehicle seat, thereby improving the operation convenience of front-rear translation.

[0065] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
