[0002] With the development of the times, people's living standards are constantly improving, and more and more families have purchased cars. Cars have greatly facilitated people's travel.

[0003] In order to ensure people's safety in cars, car seats are equipped with seat belts. Adults can wear seat belts when riding in cars, but these seat belts are not suitable for children or infants, so it is necessary to install child-specific safety seats on ordinary car seats. Most of the child safety seats on the market are equipped with built-in ISOFIX. The full name of ISOFIX is "International Standards Organization FIX", which means International Organization for Standardization Fixing Device in Chinese. The built-in flange assembly of the child safety seat can quickly connect to the ISOFIX interface of the car, realizing the quick connection and installation of the child safety seat and the car seat.

[0004] Although the above-mentioned child safety seats can meet the needs of users for quick disassembly and assembly of child safety seats, after the child safety seat is installed in the car seat, the child safety seat is generally fixed in the car and cannot be moved. For younger children or infants, an adult is required to hold the child or infant, bend over, reach into the car and place the child in the child safety seat, or an adult bends over, reaches into the car and holds the child or infant out. Due to the narrow space in the car, it is inconvenient for users to operate, and it is easy for children or adults to collide with the car. Summary of the invention

[0055] Referring to Figures 1 to 12 , a children's car seat according to some embodiments of the present invention includes a base 100, a seat body 300, and a swing arm mechanism. In this embodiment, the base 100 can be fixedly installed inside the car compartment through the car's restraint system. Since this technology is well-known in the art, it will not be elaborated here.

[0056] The base 100 has a central position, and the seat body 300 is for infants or children to sit on. When the seat body 300 is installed on the base 100, the seat body 300 is located at the central position of the base 100 or the seat body 300 covers the central position of the base 100. The swing arm mechanism is arranged between the seat 100 and the seat body 300, and the swing arm mechanism has a first rotating shaft 201 and a second rotating shaft 202. Specifically, the first rotating shaft 201 and the second rotating shaft 202 are arranged at intervals in the horizontal direction. The swing arm mechanism is rotationally connected to the base 100 through the second rotating shaft 202; the seat body 300 is rotationally connected to the first rotating shaft 201, and the seat body 300 can rotate relative to the base 100 around the first rotating shaft 201 by at least 180 degrees.

Among them, the swing arm mechanism can swing around the second rotating shaft 202 and drive the seat body 300 to deviate from the central position of the base 100, or the swing arm mechanism can swing around the second rotating shaft 202 and drive the seat body 300 to move back to the central position of the base 100.

[0057] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8, in certain embodiments of the present invention, the children's car seat further includes a seat carrier 310 for supporting the seat body 300. The seat carrier 310 is rotatably connected to the swing arm mechanism through a first rotating shaft 201. Two card slots 311 are provided on the seat carrier 310. The two card slots 311 are spaced apart relative to the first rotating shaft 201. In this embodiment, the two card slots 311 are correspondingly provided at the front end and the rear end of the seat carrier 310 respectively. The locking device includes a latch 110 and a compression spring. The latch 110 is movably installed at the front part of the base 100. The latch 110 can move relative to the base 100 closer to the central position or the latch 110 can move relative to the base 100 away from the central position. One end of the compression spring abuts against the base 100, and the other end of the compression spring abuts against the latch 110. The compression spring can apply a force to the latch 110 and make the latch 110 maintain a tendency to move closer to the central position of the base 100. The seat body 300 is detachably installed on the seat carrier 310, or the seat body 300 is fixedly installed on the seat carrier 310. When the swing arm mechanism drives the seat carrier 310 and the seat body 300 to swing back to the central position of the base 100, the latch 110 is engaged with the card slot 311 at the front end of the seat carrier 310, or the latch 110 is engaged with the card slot 311 at the rear end of the seat carrier 310. At this time, the locking device locks the seat body 300 at the central position of the base 100, so that the seat body 300 has a forward positioning position and / or a backward positioning position relative to the base 100.

[0058] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 9, to unlock the locking device for the seat carrier 310, in some embodiments of the present invention, a push rod 312 is movably installed at the front end and the rear of the seat carrier 310 respectively. One of the push rods 312 is used in pair with one of the card slots 311, and the other push rod 312 is used in pair with the other card slot 311. Each push rod 312 can move along the card slot 311 towards the outside of the seat carrier 310, or each push rod 312 can move along the card slot 311 towards the inside of the seat carrier 310. Two fork levers 314 are arranged at intervals inside the seat carrier 310. The middle parts of the two fork levers 314 are pivotally connected to the seat carrier 310. The two ends of each fork lever 314 are pivotally connected to the two push rods 312 in a one-to-one correspondence. A rotary unlocking member 315 is movably installed at the front end and the rear end of the upper surface of the seat carrier 310 respectively. The two rotary unlocking members 315 are drivingly connected to the two push rods 312 in a one-to-one correspondence. When a user applies force to one or both of the rotary unlocking members 315 to drive the push rods 312 to move towards the outside of the seat carrier 310, through the transmission of the two fork levers 314, the two push rods 312 both move along the card slot 311 towards the outside of the seat carrier 310. At this time, one of the push rods 312 can push the pin 110 stuck in the card slot 311 outwards, so as to release the clamping connection between the pin 110 and the card slot 311, and further release the locking of the locking device on the seat carrier 310. Therefore, the user can drive the seat carrier 310 to drive the seat body 300 to rotate arbitrarily relative to the base 100 around the first rotating shaft 201.

[0059] It should be noted that in the above embodiments, the children's car seat has a seat carrier 310 for supporting the seat body 300, and two card slots 311 are respectively arranged at the front end and the rear end of the seat carrier 310. In some embodiments of the present invention, the children's car seat does not have a seat carrier 310. The seat body 300 is rotationally connected to the swing arm mechanism through the first rotating shaft 201, and a card slot 311 is respectively arranged at the front end and the rear end of the seat body 300. The locking device includes a pin 110 and a compression spring. The pin 110 is movably installed at the front part of the base 100. The pin 110 can move relative to the base 100 closer to the central position or the pin 110 can move relative to the base 100 away from the central position. One end of the compression spring abuts against the base 100, and the other end of the compression spring abuts against the pin 110. The compression spring can apply force to the pin 110 and make the pin 110 keep the tendency of moving closer to the central position of the base 100. When the swing arm mechanism drives the seat body 300 to swing back to the central position of the base 100, the pin 110 is clamped with the card slot 311 at the front end of the seat body 300, or the pin 110 is clamped with the card slot 311 at the rear end of the seat body 300. At this time, the locking device locks the seat body 300 at the central position of the base 100, so that the seat body 300 has a forward positioning position and / or a backward positioning position relative to the base 100.

[0060] In some embodiments of the present invention, the swing arm mechanism includes at least two swing arms, the two swing arms are pivotally connected to each other, and the two swing arms can be relatively unfolded or relatively stacked; one of the swing arms is rotatably connected to the base 100 through the second rotating shaft 202, and the first rotating shaft 201 is disposed on the other swing arm. Specifically, one of the swing arms is the first swing arm 210, and the other swing arm is the second swing arm 220. The first swing arm 210 is rotatably connected to the base 100 through the second rotating shaft 202, and the second swing arm 220 is rotatably connected to the first swing arm 210 through the third rotating shaft 203. The second swing arm 220 is rotatably connected to the seat carrier 310 through the first rotating shaft 201.

[0061] The child car seat according to some embodiments of the present invention further includes a pressing and positioning mechanism, which can clamp and position the relative positions of the base 100 and the first swing arm 210, or the pressing and positioning mechanism can clamp and position the relative positions of the first swing arm 210 and the second swing arm 220, or the pressing and positioning mechanism can clamp and position the relative positions of the seat body 300 and the second swing arm 220.

[0062] Specifically, referring to Figures 6 to 9, in some embodiments of the present invention, the first rotating shaft 201 is fixedly disposed on the second rotating arm 220, the seat carrier 310 is movably mounted on the first rotating shaft 201, the first rotating shaft 201 at least partially extends into the interior of the seat carrier 310, and the seat carrier 310 is rotationally connected to the second rotating arm 220 through the first rotating shaft 201. The pressing and positioning mechanism includes a first pressing and positioning mechanism disposed inside the seat carrier 310. The first pressing and positioning mechanism includes a first pressing block 410, a second pressing block 420, and a second compression spring. The first pressing block 410 and the second pressing block 420 are movably mounted inside the seat carrier 310 and are respectively located on both sides of the first rotating shaft 201. The first pressing block 410 and the second pressing block 42 can move relatively closer to and cooperate to clamp the first rotating shaft 201, or the first pressing block 410 and the second pressing block 42 can move relatively away from and release the first rotating shaft 201. In this embodiment, the first pressing block 410 and the second pressing block 420 are respectively connected to two ejector rods 312 in a driving manner. The second compression spring is mounted inside the seat carrier 310. One end of the second compression spring abuts against the interior of the seat carrier 310, and the other end of the second compression spring abuts against the first pressing block 410 or the second pressing block 420. The second compression spring can drive the first pressing block 410 or the second pressing block 420 to move closer to the first rotating shaft 201. Since the two ejector rods 312 are pivotally connected through two fork levers 314, under the action of the two fork levers 314, the first pressing block 410 and the second pressing block 420 can move closer to each other or move relatively away from each other, so that the second compression spring can drive the first pressing block 410 and the second pressing block 420 to move closer to each other and clamp the first rotating shaft 201, thereby realizing the relative position positioning of the seat carrier 310 and the second rotating arm 220, that is, realizing the relative position positioning of the seat body 300 and the second rotating arm 220. In this embodiment, when the user applies a force to a certain rotation unlocking member 315 to drive the ejector rod 312 to unlock the locking device outside the seat carrier 310, the ejector rod 312 synchronously drives the first pressing block 410 and the second pressing block 420 to move relatively away from and release the first rotating shaft 201, so that the seat body 300 and the seat carrier 310 can rotate arbitrarily relative to the base 100 around the first rotating shaft 201. When rotated to a suitable position, the user removes the external force applied to the rotation unlocking member 315, and the second compression spring can drive the first pressing block 410 and the second pressing block 420 to move closer to each other and clamp the first rotating shaft 201, thereby locking and positioning the relative positions of the seat carrier 310, the seat body 300, and the second rotating arm 220.

[0063] It should be noted that, in addition to the above-mentioned structure consisting of the first pressing block 410, the second pressing block 420 and the second compression spring, the first pressing and positioning mechanism can also adopt other structures. For example, the first pressing and positioning mechanism includes the first pressing block 410 and the second compression spring. The first pressing block 410 is movably installed inside the seat carrier 310 and is located on one side of the first rotating shaft 201. The first pressing block 410 can move relative to the seat carrier 310 close to or away from the first rotating shaft 201. In this embodiment, the first pressing block 4 10 is transmission connected to one of the push rods 312, and the second compression spring is installed inside the seat carrier 310. One end of the second compression spring abuts against the inside of the seat carrier 310, and the other end of the second compression spring abuts against the first clamping block 410. The second compression spring can drive the first clamping block 410 to move close to the first rotating shaft 201, and the first clamping block 410 presses against the outer peripheral wall of the first rotating shaft 201, thereby realizing the relative position positioning of the seat carrier 310 and the second rotating arm 220, that is, realizing the relative position positioning of the seat body 300 and the second rotating arm 220. When the user applies force to a certain rotating unlocking member 315 to drive the push rod 312 to unlock the locking device outside the seat carrier 310, the push rod 312 synchronously drives the first clamping block 410 to move away and release the first rotating shaft 201, so that the seat body 300 and the seat carrier 310 can rotate arbitrarily around the first rotating shaft 201 relative to the base 100. When rotated to a suitable position, the user removes the external force applied to the rotating unlocking member 315, and the second compression spring can drive the first clamping block 410 to move closer to and clamp the first rotating shaft 201, thereby locking and positioning the relative positions of the seat carrier 310, the seat body 300 and the second rotating arm 220.

[0064] Reference Figure 6 , Figures 10 to 12In some embodiments of the present invention, the clamping and positioning mechanism includes a second clamping and positioning mechanism disposed inside the first rotating arm 210. Specifically, the second rotating shaft 202 is fixedly disposed on the base 100, the first rotating arm 210 is movably mounted on the second rotating shaft 202, and the first rotating arm 210 can rotate relative to the base 100 around the second rotating shaft 202, and the second rotating shaft 202 is at least partially inserted into the first rotating arm 210. The second clamping and positioning mechanism includes a third clamping block 430 and a third compression spring. The third clamping block 430 is movably mounted inside the first rotating arm 210 and is located at the second rotating shaft. On one side of 202, the third clamping block 430 can only move along the length direction of the first rotating arm 210 to approach or move away from the second rotating axis 202, and the third compression spring is installed inside the first rotating arm 210, one end of the third compression spring abuts against the inner wall of the first rotating arm 210, and the other end of the third compression spring abuts against the third clamping block 430. The third compression spring can apply force to the third clamping block 430 and make the third clamping block 430 press against the outer wall of the second rotating axis 202. The second rotating axis 202 is clamped by the third clamping block 430, thereby the first rotating arm 210 and the base 100 are clamped and positioned. In certain embodiments of the present invention, a first operating member 120 is movably mounted on the front upper surface of the base 100. The first operating member 120 can move along the length direction of the base 100 away from or close to the center position of the base 100. The first operating member 120 is transmission-connected to the third clamping block 430 via a first flexible member. The first flexible member refers to a component that is easily bent and deformed, such as a rope, a steel wire rope, or a soft cloth strip. In the present embodiment, the first flexible member is a steel wire rope, one end of which is connected to the first operating member 120, and the other end of the steel wire rope is connected to the third clamping block 430. When the user operates the first operating member 120 to move away from the center position of the base 100, the first operating member 120 drives the third clamping block 430 to move away from the second rotating axis 202 through the wire rope, so that the third clamping block 430 releases the second rotating axis 202 and makes the first rotating arm 210 and the base 100 in a free state, so that the first rotating arm 210 can rotate relative to the base 100 around the second rotating axis 202. If the user removes the external force applied to the first operating member 120, the third compression spring pushes the third clamping block 430 to reset and clamp the second rotating axis 202, thereby realizing the clamping positioning between the first rotating arm 210 and the base 100. By adopting the above structure, when the first rotating arm 210 rotates to any position relative to the base 100, the second clamping and positioning mechanism can clamp the third clamping block 430, thereby realizing the clamping positioning of the first rotating arm 210 relative to the base 100 to rotate to any position, thereby meeting the user's usage requirements.

[0065] The pressing and positioning mechanism further includes a third pressing and positioning mechanism disposed inside the first rotating arm 210. Specifically, the third rotating shaft 203 is fixedly disposed on the second rotating arm 220, and a part of the third rotating shaft 203 is movably inserted into the inside of the first rotating arm 210. The third pressing and positioning mechanism includes a fourth pressing block 440 movably installed inside the first rotating arm 210. The fourth pressing block 440 can only move closer to or away from the third rotating shaft 203 along the length direction of the first rotating arm 210. In this embodiment, the fourth pressing block 440 is connected to the third pressing block 430, that is, the third pressing block 430 can drive the fourth pressing block 440 to move synchronously. When the third compression spring pushes the third pressing block 430 to reset and press the second rotating shaft 202, the fourth pressing block 440 presses the third rotating shaft 203. By pressing the third rotating shaft 203 with the fourth pressing block 440, the pressing and positioning between the first rotating arm 210 and the second rotating arm 220 is realized. If the user operates the first operating member 120 to drive the third pressing block 430 to move and release the second rotating shaft 202, the fourth pressing block 440 moves away synchronously with the third pressing block 430. At this time, the fourth pressing block 440 releases the third rotating shaft 203, and at this time, the second rotating arm 220 can rotate relative to the first rotating arm 210 arbitrarily to meet the user's needs.

[0066] Referring to Figures 5 to 8 , in order to limit the rotation of the swing arm mechanism to drive the seat body 300 to rotate and deviate from the center position of the base 100, in some embodiments of the present invention, a swing control mechanism for locking the swing arm mechanism is provided at the front end or the rear end of the base. The swing control mechanism includes at least one locking member. The locking member is movably installed at one end of the base 100. At least one end of the swing arm is provided with a locking groove 140 that cooperates with the locking member for locking. The locking groove 140 can be opened at the front end or the rear end or any side wall of the locking member, which can be determined according to actual needs; wherein, when the locking groove 140 of the swing arm and the locking member are aligned with each other, the locking member can move or swing relative to the base 100 and be inserted into the locking groove 140, or the locking member can move or swing relative to the base 100 and be disengaged from the locking groove 140.

[0067] Specifically, when the swing arm mechanism drives the seat body 300 to rotate to the central position of the base 100, locking grooves 140 are provided at the ends of the first swing arm 210 and the second swing arm 220 of the swing arm mechanism facing the rear end of the base 100. A swing control mechanism for locking the swing arm mechanism is provided at the rear end of the base 100. Specifically, the swing control mechanism includes a locking member and a fourth compression spring 131. In this embodiment, the locking member is a first locking member 130. The first locking member 130 is rotatably installed at the rear end of the base 100, and the fourth compression spring 131 is also installed at the rear end of the base 100. One end of the fourth compression spring 131 abuts against the base 100, and the other end of the fourth compression spring 131 abuts against the first locking member 130. The fourth compression spring 131 can apply force and push the first locking member 130 to swing close to the central position of the base 100. Therefore, when the swing arm mechanism drives the seat body 300 to rotate to the central position of the base 100, the locking groove 140 at the end of the first swing arm 210 and the locking groove 140 at the end of the second swing arm 220 are both aligned or aligned with the first locking member 130. The fourth compression spring 131 can push the first locking member 130 and cause the first locking member 130 to correspondingly embed or snap into the locking groove 140 at the end of the first swing arm 210 and the locking groove 140 at the end of the second swing arm 220. At this time, the first locking member 130 simultaneously clamps and locks the first swing arm 210 and the second swing arm 220, and then the swing control mechanism fixes and locks the swing arm mechanism to the base 100.

[0068] In order to facilitate the user to drive the swing control mechanism to unlock and release the swing arm mechanism, in some embodiments of the invention, the first locking member 130 is connected to the first operating member 120 through a second flexible member. The second flexible member refers to a component that is easily bent and deformed. For example, the second flexible member is a rope or a wire rope or a soft cloth strip, etc. In this embodiment, the second flexible member is a wire rope. When the user drives the first operating member 120 to control the second pressing and positioning mechanism and the third pressing and positioning mechanism to correspondingly release the second rotating shaft 202 and the third rotating shaft 203, the first operating member 120 pulls the first locking member 130 to swing away from the swing arm mechanism through the second flexible member. Furthermore, the first locking member 130 disengages from the locking groove 140 at the end of the first swing arm 210 and the locking groove 140 at the end of the second swing arm 220. At this time, the first locking member 130 no longer clamps the first swing arm 210 and the second swing arm 220, and the first swing arm 210 and the second swing arm 220 can rotate relative to the base 100. Furthermore, the swing arm mechanism can rotate away from the base 100.

[0069] It should be noted that an independent second operating member may also be provided at the front end of the base 100. The second operating member can reciprocate back and forth along the length direction of the base 100. At this time, the second flexible member is no longer connected to the first operating member 120. The two ends of the second flexible member are respectively connected to the first locking member 130 and the second operating member. The user can independently control the unlocking of the first locking member 130 of the swing control mechanism by driving the second operating member, which can be determined according to specific implementation requirements.

[0070] In some embodiments of the invention, in order to better lock the swing control mechanism to the swing arm mechanism, specifically, the swing control mechanism includes two locking members, one of which is the above-mentioned first locking member 130, and the other locking member is the second locking member 150. In this embodiment, the swing control mechanism further includes a fifth compression spring 151. The second locking member 150 is movably installed at the rear end of the base 100 and is located above the first locking member 130. The second locking member 150 and the first locking member 130 are engaged with each other. The fifth compression spring 151 is installed at the rear end of the base 100. One end of the fifth compression spring 151 abuts against the base 100, and the other end of the fifth compression spring 151 abuts against the second locking member 150. The fifth compression spring 151 can apply force and push the second locking member 150 to swing close to the center position of the base 100. Therefore, when the swing arm mechanism drives the seat body 300 to rotate to the center position of the base 100, the fourth compression spring 131 can push the first locking member 130 to embed into the locking groove 140 at the end of the first rotating arm 210, and the fifth compression spring 151 can push the second locking member 150 to embed into the locking groove 140 at the end of the second rotating arm 220. At this time, the second locking member 150 is separately engaged with the second rotating arm 220, and the first locking member 130 is separately engaged with the first rotating arm 210, realizing the locking of the swing control mechanism to the swing arm mechanism. When it is necessary to unlock the swing arm mechanism, the user applies force to the first operating member 120. The first operating member 120 pulls the first locking member 130 to swing away from the first rotating arm 210 through the second flexible member. The first locking member 130 can drive the second locking member 150 to swing away from the second rotating arm 220 synchronously, thereby releasing the locking of the swing control mechanism to the swing arm mechanism and facilitating the user's operation.

[0071] Refer to Figure 13 and Figure 14, the children's car seat according to certain embodiments of the present invention is different from the above embodiments in that the swing arm mechanism in this embodiment includes a rotating arm, the rotating arm is rotatably connected to the base 100 through the second rotating shaft 202, and the seat body 300 is rotatably connected to the rotating arm through the first rotating shaft 201. Specifically, the swing arm mechanism includes a rotating arm as the first rotating arm 210, the first rotating arm 210 is rotatably connected to the base 100 through the second rotating shaft 202, the first rotating shaft 201 is provided at the bottom of the seat carrier 310, and the seat carrier 310 is rotatably mounted on the first rotating arm 210 through the first rotating shaft 201. The seat body 300 can be fixedly arranged on the seat carrier 310 or the seat body 300 can be detachably mounted on the seat carrier 310. By adopting the above structure, the first rotating arm 210 can swing relative to the base 100, driving the seat body 300 to swing closer to or away from the base 100.

[0072] It should be noted that in certain embodiments of the present invention, the first rotating shaft 201 can also be directly provided at the bottom of the seat body 300, and the seat body 300 is directly rotatably connected to the first rotating arm 210 through the first rotating shaft 201 without using the seat carrier 310, which can be determined according to actual needs.

[0073] Refer to Figure 13 and Figure 14 , in certain embodiments of the present invention, the first rotating arm 210 is provided with a first shaft hole 230 and a second shaft hole 240 arranged at intervals, and the first rotating arm 210 is also provided with a communication channel connecting the first shaft hole 230 and the second shaft hole 240. At this time, the first shaft hole 230 and the second shaft hole 240 are interconnected, and the first rotating shaft 201 is rotatably mounted in the first shaft hole 230 or the second shaft hole 240. The first rotating shaft 201 can move between the first shaft hole 230 and the second shaft hole 240, that is, the first rotating shaft 201 can move from the first shaft hole 230 to the second shaft hole 240, or the first rotating shaft 201 can move from the second shaft hole 240 to the first shaft hole 230. By adopting the above structure, the seat carrier 310 can drive the seat body 300 to move between the first shaft hole 230 and the second shaft hole 240, facilitating the user to adjust the relative position between the seat body 300 and the first rotating arm 210.

[0074] Refer to Figures 15 to 17, for the children's car seat of some embodiments of the present invention, the difference between this embodiment and the above embodiment is that, in this embodiment, the swing arm mechanism includes a rotating arm, the rotating arm is rotatably connected to the base 100 through the second rotating shaft 202, the first rotating shaft 201 is movably installed on the rotating arm, the rotating arm is movably installed with a fourth rotating shaft 204, and the fourth rotating shaft 204 and the first rotating shaft 201 are arranged at intervals; the swing arm mechanism further includes a switching device, and the switching device can control the first rotating shaft 201 or the fourth rotating shaft 204 to be rotatably connected to the seat body 300. Specifically, the rotating arm included in the swing arm mechanism is the first rotating arm 210, the first rotating arm 210 is rotatably connected to the base 100 through the second rotating shaft 202, a cavity 2101 is arranged inside the first rotating arm 210, the first rotating shaft 201 and the fourth rotating shaft 204 are floatingly installed inside the cavity 2101, and the first rotating shaft 201 and the fourth rotating shaft 204 can rise relative to the first rotating arm 210 or fall and contract inside the cavity 2101. Compression springs for pushing the first rotating shaft 201 and the fourth rotating shaft 204 to rise close to the seat tray 310 are arranged inside the cavity 2101, and the compression springs make the first rotating shaft 201 and the fourth rotating shaft 204 ensure the tendency to rise close to the seat tray 310. Third shaft holes 510 and fourth shaft holes 520 corresponding to and rotatably connected to the first rotating shaft 201 and the fourth rotating shaft 204 are respectively arranged at the bottom of the seat tray 310. The first rotating shaft 201 can be inserted into the third shaft hole 510, and the fourth rotating shaft 204 can be inserted into the fourth shaft hole 520. The switching device includes a sliding plate 2102 movably installed inside the cavity 2101. A strip-shaped slot for avoiding the first rotating shaft 201 and the fourth rotating shaft 204 is arranged in the middle of the sliding plate 2102. The first rotating shaft 201 and the fourth rotating shaft 204 are both located in the strip-shaped slot. Convex strips 2103 are respectively arranged on both sides of the bottom of the sliding plate 2102. A first guiding slope 2104 is arranged at one end of each convex strip 2103 close to the first rotating shaft 201, and a second guiding slope 2105 is arranged at one end of each convex strip 2103 close to the fourth rotating shaft 204. First connecting rod parts 2010 capable of moving along the first guiding slope 2104 are arranged on both sides of the first rotating shaft 201, and second connecting rod parts 2040 capable of moving along the second guiding slope 2105 are arranged on both sides of the fourth rotating shaft 204.

[0075] When the swing arm mechanism drives the seat carrier 310 to move to the central position of the base 100, the sliding plate 2102 is in the initial position, the first rotating shaft 201 and the convex strip 2103 are staggered from each other, the first link portions 2010 on both sides of the first rotating shaft 201 abut against the bottom of the sliding plate 2102, the first rotating shaft 201 is inserted into the third shaft hole 510 at the bottom of the seat carrier 310, and the second link portions 2040 at both ends of the fourth rotating shaft 204 abut against the lower surfaces of the two convex strips 2103. At this time, the two convex strips 2103 cooperate with the two second link portions 2040 and cause the fourth rotating shaft 204 to contract inside the cavity 2101, and the fourth rotating shaft 204 is disengaged from the fourth shaft hole 520. At this time, the seat body 300 and the seat carrier 310 can rotate relative to the central position of the base 100 around the first rotating shaft 201;

[0076] After the first rotating arm 210 drives the seat carrier 310 to drive the seat body 300 to swing away from the base 100, the user pushes the sliding plate 2102 to move relative to the first rotating arm 210. The sliding plate 2102 moves relative to the first rotating shaft 201 and the fourth rotating shaft 204. The first guiding slope 2104 then moves closer to the first link portions 2010 on both sides of the first rotating shaft 201. The first guiding slope 2104 cooperates with the first link portions 2010 to drive the first rotating shaft 201 to contract into the cavity 2101, and the first rotating shaft 201 is separated from the third shaft hole 510. The second link portions 2040 on both sides of the fourth rotating shaft 204 move along the second guiding slope 2105 and deviate from the convex strip 2103. The fourth rotating shaft 204 moves upward and is inserted into the fourth shaft hole 520. At this time, the seat carrier 310 is rotationally connected to the first rotating arm 210 through the fourth rotating shaft 204. The user can push the seat carrier 310 to drive the seat body 300 to rotate around the fourth rotating shaft 204. At this time, the seat carrier 310 drives the seat body 300 to swing away from the first rotating arm 210 around the fourth rotating shaft 204, so that the swing arm mechanism can drive the seat body 300 to move to a position farther away from the base 100 to meet the user's needs. If it is necessary to switch the first rotating shaft 201 to be inserted into the third shaft hole 510, only need to reversely rotate the seat carrier 310 until the first rotating shaft 201 is aligned with the third shaft hole 510 and the fourth rotating shaft 204 is aligned with the fourth shaft hole 520, and then the user reversely moves the sliding plate 2102 again, which can be determined according to actual needs.

[0077] Refer to Figures 1 to 12, The child car seat according to some embodiments of the present invention includes a base 100, a swing arm mechanism, and a seat body 300. The base 100 has a central position. The swing arm mechanism includes a first swing arm 210 and a second swing arm 220. The first swing arm 210 and the second swing arm 220 are pivotally connected. The seat body 300 is rotatably mounted on the second swing arm 220. The seat body 300 covers the central position of the base 100. Wherein, the seat body 300 can swing away from the central position of the base 100 through the swing arm mechanism, or the seat body 300 can swing to the central position of the base 100 through the swing arm mechanism, and / or the seat body 300 can rotate relative to the swing arm mechanism.

[0078] Specifically, the first swing arm 210 is connected to the base 100. The second swing arm 22 is provided with a first rotating shaft 201. The seat body 300 is rotationally connected to the swing arm mechanism through the first rotating shaft 201. The seat body 300 can rotate at least 180 degrees relative to the central position of the base 100 around the first rotating shaft 201. A locking device is provided on the base 100. The locking device can lock the seat body 300 at the central position of the base 100, so that the seat body 300 has a forward positioning position and a backward positioning position relative to the base 100. The locking device in this embodiment is the same as the locking device in the above embodiment, and will not be described in detail here.

[0079] Refer to Figures 1 to 16 , The child car seat according to some embodiments of the present invention includes a base 100, a seat body 300, a swing arm mechanism, and a swing control mechanism; the swing arm mechanism is arranged between the base 100 and the seat body 300. The swing arm mechanism includes at least two rotatable swing arms. One of the swing arms is rotatably connected to the base 100, and the other swing arm is connected to the seat body 300. The swing arm mechanism can drive the seat body 300 away from or close to the base 100; the swing control mechanism is arranged between the base 100 and the swing arm mechanism. The swing control mechanism can lock and limit the rotation of at least one swing arm.

[0080] Specifically, refer to Figures 5 to 8, the swing arm mechanism includes a first swing arm 210 and a second swing arm 220. When the swing arm mechanism drives the seat body 300 to rotate to the central position of the base 100, locking grooves 140 are formed at one ends of the first swing arm 210 and the second swing arm 220 of the swing arm mechanism facing the first locking member 130. The swing control mechanism is arranged at the rear end of the base 100 and includes a first locking member 130 and a fourth compression spring 131. The first locking member 130 is rotatably mounted at the rear end of the base 100, and the fourth compression spring 131 is also mounted at the rear end of the base 100. One end of the fourth compression spring 131 abuts against the base 100, and the other end of the fourth compression spring 131 abuts against the first locking member 130. The fourth compression spring 131 can apply force and push the first locking member 130 to swing close to the central position of the base 100. Therefore, when the swing arm mechanism drives the seat body 300 to rotate to the central position of the base 100, the fourth compression spring 131 can push the first locking member 130 and make the first locking member 130 correspondingly snap into the locking groove 140 at the end of the first swing arm 210 and the locking groove 140 at the end of the second swing arm 220. At this time, the first locking member 130 simultaneously clamps and locks the first swing arm 210 and the second swing arm 220, and then the swing control mechanism fixes and locks the swing arm mechanism to the base 100.

[0081] In order to facilitate the user to drive the swing control mechanism to unlock and release the swing arm mechanism, in some embodiments of the invention, the first locking member 130 is connected to the first operating member 120 through a second flexible member. The second flexible member refers to a component that is easily bent and deformed. For example, the second flexible member is a rope or a steel wire rope or a soft cloth strip, etc. In this embodiment, the second flexible member is a steel wire rope. When the user drives the first operating member 120 to control the second pressing and positioning mechanism and the third pressing and positioning mechanism to correspondingly release the second rotating shaft 202 and the third rotating shaft 203, the first operating member 120 pulls the first locking member 130 to swing away from the swing arm mechanism through the second flexible member. Then, the first locking member 130 disengages from the locking groove 140 at the end of the first swing arm 210 and the locking groove 140 at the end of the second swing arm 220. At this time, the first locking member 130 is no longer clamped with the first swing arm 210 and the second swing arm 220, and the first swing arm 210 and the second swing arm 220 can rotate relative to the base 100, and then the swing arm mechanism can rotate away from the base 100.

[0082] It should be noted that an independent second operating member can also be arranged at the front end of the base 100. The second operating member can reciprocate back and forth along the length direction of the base 100. At this time, the second flexible member is no longer connected to the first operating member 120, and the two ends of the second flexible member are correspondingly connected to the first locking member 130 and the second operating member respectively. The user can separately control the first locking member 130 to unlock the swing control mechanism by driving the second operating member, which can be determined according to actual needs.

[0083] In some embodiments of the invention, in order to enable the swing control mechanism to better lock the swing arm mechanism, specifically, the swing control mechanism further includes a second locking member 150 and a fifth compression spring 151. The second locking member 150 is movably installed at the rear end of the base 100 and is located above the first locking member 130. The second locking member 150 is engaged with the first locking member 130. The fifth compression spring 151 is installed at the rear end of the base 100. One end of the fifth compression spring 151 abuts against the base 100, and the other end of the fifth compression spring 151 abuts against the second locking member 150. The fifth compression spring 151 can apply a force to push the second locking member 150 to swing closer to the center position of the base 100. Therefore, when the swing arm mechanism drives the seat body 300 to rotate to the center position of the base 100, the fourth compression spring 131 can push the first locking member 130 to embed into the locking groove 140 at the end of the first rotating arm 210, and the fifth compression spring 151 can push the second locking member 150 to embed into the locking groove 140 at the end of the second rotating arm 220. At this time, the second locking member 150 is separately engaged with the second rotating arm 220, and the first locking member 130 is separately engaged with the first rotating arm 210, realizing that the swing control mechanism locks the swing arm mechanism. When it is necessary to unlock the swing arm mechanism, the user applies a force to the first operating member 120. The first operating member 120 pulls the first locking member 130 to swing away from the first rotating arm 210 through the second flexible member, and the first locking member 130 can drive the second locking member 150 to swing away from the second rotating arm 220 synchronously, thereby releasing the locking of the swing control mechanism on the swing arm mechanism and facilitating the user's operation.

[0084] In some embodiments of the present invention, the second rotating arm 220 is provided with a first rotating shaft 201. The seat body 300 is rotatably connected to the swing arm mechanism through the first rotating shaft 201. The seat body 300 can rotate relative to the center position of the base 100 around the first rotating shaft 201 by at least 180 degrees; the base 100 is further provided with a locking device, and the locking device can lock the seat body 300 to the base 100 so that the seat body 300 has a forward positioning position and a backward positioning position relative to the base 100. Since the locking device in this embodiment is the same as the locking device in the above embodiment, it will not be described in detail here.

[0085] Refer to Figure 17In some embodiments of the child car seat of the present invention, the difference between this embodiment and the above-mentioned embodiment lies in the specific structure of the swing control mechanism. Specifically, the swing control mechanism includes a first limiter 610, a second limiter 620 and a control assembly. The first limiter 610 and the second limiter 620 are floatingly installed on both sides of the base 100. The first limiter 610 and the second limiter 620 can be lifted and lowered relative to the base 100. The control assembly is transmission-connected to the two limiters. In this embodiment, the control assembly includes a first control member 630 and a second control member 640 movably installed at the front end of the base 100. The first control member 630 is transmission-connected to the first limiter 610 through a rope, and the second control member 640 is transmission-connected to the second limiter through a rope. The first limiting member 610 and the second limiting member 620 are connected by transmission to each other. When the seat body 300 is swung to the center position of the base 100 through the swing arm mechanism, the first limiting member 610 and the second limiting member 620 are respectively located on both sides of the swing arm mechanism. At this time, the first limiting member 610 and the second limiting member 620 can limit the swing arm mechanism from swinging to both sides relative to the base 100. If the user needs to allow the swing arm mechanism to drive the seat body 300 to swing in a certain direction away from the base 100, the user can push the first control member 630 or the second control member 640. The first control member 630 or the second control member 640 can pull the first limiting member 610 or the second limiting member 620 downward by a rope to avoid the swing arm mechanism, and then the swing arm mechanism drives the seat body 300 to swing to one side away from the base 100.

[0087] The blocking device includes a trigger part 710 and a linking member 720 movably mounted on the seat carrier 310. The trigger part 710 is movably mounted on the upper part of the seat carrier 310. The trigger part 710 protrudes from the upper surface of the seat carrier 310, and the trigger part 710 can move relative to the seat carrier 310 toward the inside of the seat carrier 310. The linking member 720 is movably mounted inside the seat carrier 310, and one end of the linking member 720 faces the slot 311 at one end of the seat carrier 310. The linking member 720 can move along the seat carrier 310 to approach or move away from the slot 311. In this embodiment, the trigger part 710 and the linking member 720 are transmission connected. Specifically, a guiding inclined groove 711 is opened on the side wall of the trigger part 710, and a sliding pin cooperating with the inclined groove 711 is provided at one end of the linking member 720, and the sliding pin is slidably mounted inside the inclined groove 711.

[0088] When the swing arm mechanism drives the seat carrier 310 and the seat body 300 to swing to the center position of the base 100, the locking device of the base 100 is embedded in the slot 311 at the end of the seat carrier 310, and the locking device locks the seat body 300 to the base 100, and makes the seat body 300 have a forward positioning position or a rearward positioning position relative to the base 100.

[0089] If the seat body 300 is a specification model that is not suitable for forward positioning and installation relative to the base 100, such as a basket-type car seat, the lower part of the seat body 300 will squeeze the trigger part 710 to move inside the seat carrier 310, and the trigger part 710 drives the linkage 720 to move toward the slot 311 through the inclined groove 711 and the sliding pin, and the end of the linkage 720 is inserted into the slot 311 at one end of the seat carrier 310, thereby preventing the locking device of the base 100 from being engaged with the slot 311 into which the linkage 720 has been inserted. At this time, the locking device cannot lock the seat carrier 310 and the seat body 300 to the base 100, that is, the seat body 300 is prevented from being positioned and installed toward the front of the base 100. Since the locking device of this embodiment has the same structure as the locking device of other embodiments, it will not be repeated here.
