DETAILED DESCRIPTION

[0137] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0138] The following descriptions of directions such as front, back, left, right, up, and down are defined based on the directions as viewed by a child in the safety seat when the safety seat is installed in the correct orientation on the car seat. Their purpose is simply to clearly illustrate the relative positional relationships of the various components of the safety seat.

[0139] Referring to the accompanying drawings, the present invention provides a safety seat, which includes a base 1 and a seat 2, wherein the seat 2 has a first position and a second position relative to the base 1, and the safety seat also includes an actuating structure arranged between the base 1 and the seat 2, and the seat 2 can be moved relative to the base 1 via the actuating structure, wherein when the seat 2 is in the first position, the orientation of the seat 2 is a first direction; when the seat 2 moves to the second position via the actuating structure, the axis of the seat 2 deviates from the axis of the seat 2 when it is in the first position, and the orientation of the seat 2 is a second direction different from the first direction.

[0140] Specifically, the seat 2 includes a load-bearing body and a load-bearing member 20. The load-bearing member 20 is disposed at the bottom of the load-bearing body and is engaged with the load-bearing body. A support member 3 is disposed on the base 1. As shown in FIG7 , the seat 2 is connected to the base 1 via the load-bearing member 20, specifically to the support member 3 on the base 1. The load-bearing member 20 is disposed between the support member 3 and the load-bearing body. The load-bearing body and the load-bearing member 20 may be integrally or separately provided, and the two may be assembled or disassembled. Thus, different load-bearing bodies may be selected according to usage needs and engaged with the load-bearing member 20 and then installed on the base 1. The load-bearing body may specifically be a carrier 21 as shown in FIG1 , FIG2 and FIG5 , which is suitable for use by infants and young children of younger age groups, or a safety seat 22 as shown in FIG3 , FIG4 and FIG6 , which is suitable for use by older children.

[0141] The above-mentioned first direction can be forward or backward, and correspondingly, the second direction is left or right, that is, when the seat 2 is in the first position, it faces forward or backward, and when the seat 2 is converted to the second position, it faces left or right.

[0142] Specifically, referring to Figures 1 and 2, the supporting body of the seat 2 is the carry basket 21. In the state shown in Figure 1, the carry basket 21 is in the first position and faces rearward; in the state shown in Figure 2, the carry basket 21 is in the second position, facing rightward. The axis of the carry basket 21 in the state of Figure 2 deviates from the axis of the carry basket 21 in the state of Figure 1, and the carry basket 21 protrudes further outward in the left and right directions relative to the base 1. In this way, when the safety seat is installed on the car seat, when the carry basket 21 is converted to the second position, the carry basket 21 can be closer to the door frame of the car, and even partially extend out of the door frame, which makes it convenient for parents to place the child on the carry basket 21 and restrain the child on the carry basket 21.

[0143] Similarly, referring to Figures 3-4 and 6, the main support structure of the seat 2 is a safety seat 22, which is suitable for older children. In Figure 3, the safety seat 22 is in the first position and faces forward. In Figure 4, the safety seat 22 is in the second position, facing right. The axis of the safety seat 22 in Figure 4 deviates from the axis of the safety seat 22 in Figure 3, and the safety seat 22 protrudes further outward in the left-right direction relative to the base 1, making it easier for parents to place and restrain their children in the safety seat 22.

[0144] In some embodiments, the seat 2 further has a third position symmetrically arranged with the second position. The seat 2 can also be moved to the third position via an actuating structure. The orientation of the seat 2 in the third position is opposite to the orientation of the seat 2 in the second position. That is, the seat 2 is oriented rightward and leftward in the second and third positions, respectively. This allows the user to conveniently select the second or third position based on the safety seat's installation position on the vehicle seat, so that the seat 2 faces the corresponding vehicle door.

[0145] In some embodiments, for a safety seat, when the seat 2 moves from the first position to the second position via the aforementioned actuating structure, a smooth first movement trajectory is formed, and the seat 2 can continuously rotate relative to the base 1 along the first movement trajectory. When the seat 2 moves from the first position to the third position via the aforementioned actuating structure, a smooth second movement trajectory is formed, and the seat 2 can also continuously rotate relative to the base 1 along the second movement trajectory. The first movement trajectory and the second movement trajectory are arranged in an intersecting manner, and the seat 2 always remains in the same plane when moving along the first movement trajectory and the second movement trajectory. As an optional embodiment, the first movement trajectory and the second movement trajectory are located in the same horizontal plane.

[0146] In the first embodiment, as shown in Figures 7 to 15 , the actuating structure includes a first shaft 4 and a second shaft 5 . The first shaft 4 and the second shaft 5 are disposed on the seat 2 , specifically, on the support member 20 of the seat 2 . When the seat 2 moves along a first movement trajectory W1 , the first shaft 4 is fixed axially and rotates circumferentially relative to the base 1 or the seat 2 , and the seat 2 moves along the first movement trajectory W1 , as shown in Figure 14 . When the seat 2 moves along a second movement trajectory W2 , the second shaft 5 is fixed axially and rotates circumferentially relative to the base 1 or the seat 2 , and the seat 2 moves along the second movement trajectory W2 , as shown in Figure 15 . Specifically, the base 1 has a first central axis M1 extending longitudinally. When the seat 2 is in the first position, the axis centers of the first shaft 4 and the second shaft 5 are symmetrically distributed on either side of the first central axis M1 of the base 1 and near the front end of the base 1 .

[0147] In the first embodiment shown in Figures 7 to 15 , the actuating structure further includes two first and second chute grooves 31, 32, respectively disposed opposite the first and second shafts 4, 5. The first and second chute grooves 31, 32 are disposed on the base 1 and extend in an arc-shaped, intersecting pattern, allowing the first and second shafts 4, 5 to drive the seat 2 to move within the first and second chute grooves 31, 32, respectively. The centers of the first and second chute grooves 31, 32 are offset from the first central axis M1 of the base 1. Here, the first and second chute grooves 31, 32 are disposed on the support member 3. A first movement trajectory W1 overlaps or partially overlaps with the first chute groove 31, with its starting point and endpoint being at the two ends of the first chute groove 31. A second movement trajectory W2 overlaps or partially overlaps with the first chute groove 32, with its starting point and endpoint being at the two ends of the first chute groove 32. The support member 3 is disc-shaped and can rotate on the base 1 around a center line extending in the vertical direction, so that the support member 3 rotates 180° or 360° as a whole, so that the seat 2 can switch between the forward direction and the backward direction. The center of the first slide grooves 31 and 32 also deviates from the center of the support member 3.

[0148] As shown in Figure 14, when the seat 2 moves from the first position to the second position, the axial direction of the first shaft 4 is fixed, and the second shaft 5 drives the seat 2 to move in the first slide groove 31, so that the seat 2 as a whole rotates continuously around the axis of the first shaft 4, thereby reaching the second position; as shown in Figure 15, when the seat 2 moves from the first position to the third position, the axial direction of the second shaft 5 is fixed, and the first shaft 4 drives the seat 2 to move in the second slide groove 32, so that the seat 2 as a whole rotates continuously around the second shaft 5, thereby reaching the third position.

[0149] As shown in Figures 13, 14 and 15, when the seat 2 is in the first position, it has a first axis extending in the vertical direction, and its projection on the top view is P1. The first axis intersects the first central axis M1 of the base 1 perpendicularly; the seat 2 has a second central axis M2 extending longitudinally, and the second central axis M2 coincides with the first central axis M1 of the base 1, and the projection P1 falls on the second central axis M2 of the seat 2.

[0150] When the seat 2 is in the second position or the third position, the second central axis M2 of the seat 2 rotates a certain angle, specifically to be perpendicular to the first central axis M1 of the base 1. The seat 2 has a second axis extending in the vertical direction, whose projection on the top view is P2. Along the second direction, the distance between the first axis and the second axis, that is, the distance L between P1 and P2>0, for example 50mm <L<250mm。

[0151] In other embodiments, the first shaft 4 and the second shaft 5 may be disposed on the base 1 , and the first sliding groove 31 and the second sliding groove 32 may be disposed on the seat 2 .

[0152] Referring to Figures 16 to 23 , a second embodiment of a safety seat is provided. In this embodiment, the actuating structure further includes two grooves 201 disposed opposite the first shaft 4 and the second shaft 5, respectively. The first shaft 4 and the second shaft 5 are axially retractably disposed on one of the seat 2 and the base 1. The grooves 201 are disposed on the other of the base 1 and the seat 2, allowing the first shaft 4 and the second shaft 5 to be inserted into and removed from the grooves 201. Specifically, the first shaft 4 and the second shaft 5 can be configured to slide axially to achieve axial extension and contraction relative to the seat 2 or the base 1, or to shorten axially to achieve axial extension and contraction relative to the seat 2 or the base 1. Here, the first shaft 4 and the second shaft 5 are disposed on the support member 3 of the base 1, while the two grooves 201 are disposed on the seat 2, specifically, on the carrier 20 of the seat 2. During the process of the seat 2 being converted from the first position to the second position, as shown in Figure 17, the second shaft 5 disengages from the groove 201, so that the seat 2 rotates around the first axis 4 relative to the base 1, thereby reaching the second position along the first movement trajectory; during the process of the seat 2 being converted from the first position to the third position, as shown in Figure 18, the first shaft 4 disengages from the groove 201, so that the seat 2 rotates around the second axis 5 relative to the base 1, thereby reaching the third position along the second movement trajectory.

[0153] In some embodiments, a first guide track is formed when seat 2 moves from the first position to the second position, and a second guide track is formed when seat 2 moves from the first position to the third position. Since the third position is symmetrical with the second position, the first guide track and the second guide track are symmetrically arranged, ensuring that seat 2 can move smoothly and stably to the second position or the third position. Optionally, the first guide track and the second guide track are symmetrically arranged with respect to the first central axis M1 of the base 1, so that the outer positions of seat 2 in the second and third positions are symmetrical with respect to the first central axis M1 of the base 1.

[0154] Based on the above-mentioned first moving trajectory W1 and second moving trajectory W2, in order to enable the seat 2 to smoothly move between the first position and the second position or the first position and the third position, the first guide trajectory and the second guide trajectory are both smooth arcs, and the first guide trajectory and the second guide trajectory are arranged crosswise. Optionally, the first guide trajectory coincides with the second moving trajectory W2, and the second guide trajectory coincides with the first moving trajectory W1, that is, when the first shaft 4 slides in one of the first slide grooves 31 to form the first moving trajectory, the trajectory of the second shaft 5 sliding in the other first slide groove 32 is the first guide trajectory, and when the second shaft 5 slides in the other first slide groove 32 to form the second moving trajectory, the trajectory of the first shaft 4 sliding in one of the first slide grooves 31 is the second guide trajectory. The cooperation between the first shaft 4 and the first slide groove 32 and the cooperation between the second shaft 5 and the first slide groove 32 respectively have two functions, which simplifies the connection structure between the seat 2 and the base 1.

[0155] The safety seat further includes a locking structure 6 and an unlocking structure 7. The locking structure 6 is provided on one of the seat 2 and the base 1 for selectively locking the first shaft 4 and / or the second shaft 5. The unlocking structure 7 is connected to the locking structure 6 and is used to release the locking structure 6.

[0156] Referring to the embodiments shown in Figures 7 to 15, the locking structure 6 includes a locking member that can lock the first shaft 4 and / or the second shaft 5, and the locking member is rotatably provided on the base 1; the unlocking structure 7 includes an unlocking member, and the unlocking member is connected to the locking member through a traction member. When the unlocking member is unlocked, the locking member is driven by the traction member to rotate relative to the base 1 and unlocked.

[0157] The safety seat also includes a limiting structure disposed between the locking member and the traction member. The limiting structure includes a connecting portion and a raised portion. The connecting portion connects the locking member and the traction member and is provided with a fifth groove. The raised portion is slidably disposed in the fifth groove. When the unlocking member is unlocked, the unlocking member drives the fifth groove to slide relative to the raised portion via the traction member, thereby limiting the movement distance of the locking member and defining the rotation trajectory of the locking member when the locking member rotates relative to the base 1. An elastic member for resetting can be provided between the base 1 and the unlocking structure 7.

[0158] Specifically, in the embodiment, the locking structure 6 includes two locking members, namely a first locking member 61 and a second locking member 62. The first locking member 61 is configured to lock the first shaft 4, and the second locking member 62 is configured to lock the second shaft 5. The first locking member 61 is rotatably disposed on the base 1 about a first rotation axis 63, and the second locking member 62 is rotatably disposed on the base 1 about a second rotation axis 65. The unlocking structure 7 includes two unlocking members, namely a first unlocking button 73 and a second unlocking button 74. One end of a first spring 67 and a second spring 68 are connected to the base 1, and the other ends are connected to the first unlocking button 73 and the second unlocking button 74 respectively via a linkage structure of the unlocking structure 7. The first unlocking button 73 is connected to the second locking member 62 via a first pulling member 71, and can drive the second locking member 62 to rotate and unlock relative to the base 1. The second unlocking button 74 is connected to the first locking member 61 via a second pulling member 72, and can drive the first locking member 61 to rotate and unlock relative to the base 1.

[0159] More specifically, as shown in Figure 12, the first locking member 61 includes a first locking portion 611 and a first connecting portion 612. The first locking portion 611 can be the free end of the first locking member 61. The first locking portion 611 is used to hook the first shaft 4 to fix it relative to the base 1. The first connecting portion 612 is used to connect with the second traction member 72. The first locking portion 611 and the first connecting portion 612 are arranged on different sides of the first rotating shaft 63. The first connecting portion 612 is also provided with a fifth groove, which is specifically a first guide groove 613 here. The first guide groove 613 is an arc groove with the axis of the first rotating shaft 63 as the rotation center. The base 1 is also provided with a first protrusion, which is specifically a first guide column 64 here. The first guide column 64 can be relatively slidably inserted in the first guide groove 613. The two cooperate with each other to provide guidance for the first locking member 61 when it rotates around the first rotating shaft 63.

[0160] Similarly, the second locking member 62 includes a first locking portion 621 and a second connecting portion 622. The first locking portion 621 can be the free end of the first locking portion 621. The second locking portion 621 is used to hook the second shaft 5 to fix it relative to the base 1. The second connecting portion 622 is used to connect with the first traction member 71. The second locking portion 621 and the second connecting portion 622 are arranged on different sides of the second rotating shaft 65. A second guide groove 623 is also provided on the second connecting portion 622. The second guide groove 623 is an arc-shaped groove with the axis of the second rotating shaft 65 as the rotation center. A second guide column 66 is also provided on the base 1. The second guide column 66 is inserted into the second guide groove 623. The two cooperate with each other to provide guidance for the second locking member 62 when it rotates around the second rotating shaft 65.

[0161] When the first unlocking button 73 is operated, the second traction member 72 pulls the second connecting portion 622 to make the second locking member 62 rotate around the second rotating shaft 65 in a third direction (clockwise in the embodiment), the second spring 68 is stretched, and the second locking portion 621 moves away from the second shaft 5 to release the hook on the second shaft 5, and then drives the seat 2 to rotate, and the second shaft 5 can move in the first slide groove 32, so that the seat 2 rotates around the first axis 4 and moves relative to the base 1 along the first moving trajectory, thereby switching the seat 2 from the first position to the second position. During the process, the second locking member 62 switches from the state of locking the second shaft 5 to the state of releasing the second shaft 5. When the seat 2 switches from the second position to the first position, the second traction member 72 pulls the second connecting part 622 so that the second locking member 62 rotates in the opposite direction around the second rotating shaft 65, the second spring 68 resets, and the first locking part 621 hooks the second shaft 5. During the process, the second locking member 62 switches from a state of releasing the second shaft 5 to a state of locking the second shaft 5, and the first locking member 61 always locks the first shaft 4 or releases the first shaft 4.

[0162] When the second unlocking button 74 is operated, the first pulling member 71 pulls the first connecting portion 612, causing the first locking member 61 to rotate about the first rotating axis 63. This stretches the first spring 67, causing the first locking portion 611 to move away from the first shaft 4, releasing the hook on the first shaft 4. This then causes the seat 2 to rotate, allowing the first shaft 4 to move within the first guide slot 31, causing the seat 2 to rotate about the second axis 5 and move relative to the base 1 along the second movement trajectory, thereby switching the seat 2 from the first position to the third position. During this process, the first locking member 61 switches from locking the first shaft 4 to releasing it. When the seat 2 switches from the second position to the first position, the first pulling member 71 pulls the first connecting portion 612, causing the first locking member 61 to rotate in the opposite direction about the first rotating axis 63. The first spring 67 resets, and the first locking portion 621 hooks onto the second shaft 5. During this process, the first locking member 61 switches from releasing the first shaft 4 to locking it. The second locking member 62 always locks or releases the second shaft 5.

[0163] In the embodiment shown in Figures 16 to 23 , the arrangement of the locking structure 6 differs from that shown in Figures 7 to 15 . Specifically, in the locking structure 6 , the first locking member 61 and the second locking member 62 cooperate with the mating structure and the elastic member 8 to cause the first shaft 4 and the second shaft 5 to extend axially toward the carrier 20 and to be inserted into the corresponding groove 201 .

[0164] A matching structure is provided between the first locking member 61 and the first shaft 4 so that the first shaft 4 can be driven to retract away from the supporting member 20 after the first locking member 61 is driven to rotate. The matching structure can be a wedge-shaped surface structure provided between the two. As shown in FIG22 , the first shaft 4 is provided with a first inclined surface 41, and a second inclined surface 61a is provided below the first locking member 61. The first locking member 61 has a second locking portion 61b. The second locking portion 61b can be the free end of the first locking member 61 or a part of the closed loop of the first locking member 61 and corresponds to the starting end of the second inclined surface 61a (as shown in FIG22 ). When the first locking member 61 is in the locked position, the area of ​​the second inclined surface 61a acting on the first inclined surface 41 is small, causing the first inclined surface 41 to be higher relative to the second inclined surface 61a, and the first shaft 4 is inserted into the corresponding groove 201. When the first locking member 61 rotates about the first shaft 4, the area of ​​the second inclined surface 61a acting on the first inclined surface 41 gradually increases, forcing the first shaft 4 to slide downward or shorten, and the second locking portion 61b moves toward the first shaft 4, thereby disengaging the first shaft 4 from the corresponding groove 201 and achieving unlocking. Similarly, a mating structure is also provided between the second locking member 62 and the second shaft 5. When the second locking member 62 is driven to rotate, it can drive the second shaft 5 to slide or shorten away from the carrier 20, thereby disengaging the second shaft 5 from the corresponding groove 201 and achieving unlocking.

[0165] In this way, when the first unlocking button 73 is operated to unlock, the second traction member 72 pulls the second locking member 62 to rotate around the second axis 5, and the second locking member 62 rotates in a fourth direction opposite to the third direction (counterclockwise in the embodiment), and the second inclined surface 61a pushes the first inclined surface 41 to move downward, and then the second axis 5 slides or retracts axially downward, and the free end of the second locking member 62 moves in a direction close to the second axis 5, so that the second axis 5 disengages from the groove 201 on the supporting member 20 to achieve unlocking, and then drives the seat 2 to rotate, and the seat 2 rotates around the first axis 4 and moves relative to the base 1 along the first moving trajectory, so that the seat 2 switches from the first position to the second position.

[0166] When the second unlocking button 74 is operated to unlock, the first traction member 71 pulls the first locking member 61 to rotate around the first axis 4, and the second inclined surface 61a pushes the first inclined surface 41 to move downward, and then the first axis 4 slides downward or retracts axially to make the free end of the first locking member 61 move toward the direction close to the first axis 4, so that the first axis 4 disengages from the groove 201 on the supporting member 20 to achieve unlocking, and then drives the seat 2 to rotate, and the seat 2 rotates around the second axis 5 and moves relative to the base 1 along the second moving trajectory, so that the seat 2 switches from the first position to the third position.

[0167] In other embodiments, FIGS. 24 and 25 are schematic views of the seat 2 in the first position, and FIGS. 26 and 27 are schematic views of the seat 2 in the second or third position. As shown in FIGS. 24 to 27, the first movement trajectory and the second movement trajectory are not arranged to cross each other, and the seat 2 is always located in the same plane when moving along the first movement trajectory and along the second movement trajectory. As an optional manner, the first movement trajectory and the second movement trajectory are located in the same horizontal plane.

[0168] The base 1 has a base axis a, the seat 2 has a second central axis M2 extending longitudinally along the seat 2 and an axis b perpendicular to and intersecting the second central axis M2, the axis b is parallel to the base axis a. When the seat 2 is in the first position, the axis b coincides with the base axis a. When the seat 2 is in the second or third position, the base axis a intersects the second central axis M2, and the distance L between the base axis a and the axis b is greater than 0, for example, 50 mm < L < 250 mm. When the seat 2 is in the second or third position, the seat 2 does not generate displacement in the front-back direction and extends a distance of L in the left or right direction. When the user places a child on the seat 2 or takes the child off the seat 2, there is no need to bend down or stretch the body into the vehicle for operation, which is more convenient to use.

[0169] For the third embodiment, the actuating structure includes a first shaft 4 and a second shaft 5 provided on one of the seat 2 and the base 1, and the other of the seat 2 and the base 1 is provided with a third sliding groove 43 and a fourth sliding groove 44 corresponding to the first shaft 4 and the second shaft 5. Both the third sliding groove 43 and the fourth sliding groove 44 are linear grooves. When the seat 2 moves along the first movement trajectory, the seat 2 is axially fixed and rotates relative to the base 1, the first shaft 4 slides into the third sliding groove 43, and the second shaft 5 slides out of the fourth sliding groove 44, forming the first movement trajectory, without affecting the rotation of the seat 2 relative to the base 1, so that the seat 2 provided can move from the first position to the second position. When the seat 2 moves along the second movement trajectory, the seat 2 is axially fixed and rotates relative to the base 1, the second shaft 5 slides into the fourth sliding groove 44, and the first shaft 4 slides out of the third sliding groove 43, forming the second movement trajectory, without affecting the rotation of the seat 2 relative to the base 1, so that the seat 2 provided can move from the first position to the third position. Optionally, the third sliding groove 43 and the fourth sliding groove 44 are provided on the seat 2, and the first shaft 4 and the second shaft 5 are provided on the base 1. The seat 2 is rotatably connected to the base 1, and the first shaft 4 and the second shaft 5 can rotate along their respective axes, ensuring that the seat 2 can rotate smoothly.

[0170] As shown in Figures 28 and 29, one end of the third slide groove 43 is set through the edge of the seat 2 or the base 1 and forms a first opening at the edge of the seat, so that the first shaft 4 can slide out of the third slide groove 43 from the first opening. One end of the fourth slide groove 44 is set through the edge of the seat 2 or the base 1 and forms a second opening at the edge of the seat, so that the second shaft 5 can slide out of the fourth slide groove 44 along the second opening. The matching structure is simple.

[0171] The first opening is larger than the third chute 43, and the second opening is larger than the fourth chute 44. The relatively large sizes of the first and second openings can provide a certain guide effect, facilitating the first shaft 4 to enter the third chute 43 and the second shaft 4 to enter the fourth chute 44.

[0172] When the seat 2 is in the first position, the third and fourth chute 43, 44 are symmetrically arranged relative to the first central axis M1 of the base 1. The third and fourth chute 43, 44 are located at the rear end of the seat 2 or base 1, and the third and fourth chute 43, 44 are inclined from the edge of the seat 2 or base 1 toward the first central axis M1 of the base 1. In other embodiments, the third and fourth chute 43, 44 may also be located at the front end of the seat 2 or base 1, symmetrically arranged relative to the third and fourth chute 43, 44 located at the rear end.

[0173] Figures 30 and 31 illustrate intermediate positions of the seat 2 as it rotates from the first position to the second or third position. As shown in Figures 29 to 31 , one of the seat 2 and the base 1 is provided with a sliding shaft 54, and the other of the seat 2 and the base 1 is provided with a sliding groove 55. The sliding shaft 54 ​​slides within the sliding groove 55. When the seat 2 moves from the first position to the second position, one end of the sliding groove 55 limits the rotation angle of the seat 2. When the seat 2 moves from the first position to the third position, the other end of the sliding groove 55 limits the rotation angle of the seat 2, preventing excessive rotation of the seat 2. Optionally, the sliding groove 55 is a semicircular groove. When the seat 2 is in the first position, the sliding groove 55 is symmetrically arranged relative to the first central axis M1 of the base 1, with the sliding shaft 54 ​​positioned in the middle of the sliding groove 55. When the seat 2 is in the second position, the sliding shaft 54 ​​is positioned at one end of the sliding groove 55, and when the seat 2 is in the third position, the sliding shaft 54 ​​is positioned at the other end of the sliding groove 55. When the seat 2 is placed in the second position or the third position, the sliding slot 55 limits the seat 2 to only be able to rotate 90°, which can meet the needs of users and facilitate users to take children from the safety seat.

[0174] When seat 2 moves from the first position to the second position, a first guide track is formed. When seat 2 moves from the first position to the third position, a second guide track is formed. The first guide track and the second guide track are symmetrically arranged. Because the third position is symmetrical with the second position, the first guide track and the second guide track are symmetrically arranged, ensuring that seat 2 can move smoothly and stably to the second position or the third position. Optionally, the first guide track and the second guide track are symmetrically arranged relative to the first central axis M1 of the base 1, so that the outer positions of seat 2 in the second and third positions are symmetrical relative to the first central axis M1 of the base 1.

[0175] The first guide track and the second guide track are both straight lines, and the first guide track is connected to the second guide track. The first guide track and the second guide track are both independent motion tracks, that is, the first guide track does not intersect with the first moving track, and the second guide track does not intersect with the second moving track. Optionally, a sliding member 53 is provided on one of the seat 2 and the base 1 and is connected to the sliding member 53 in a circumferential rotation, and the other is provided with a base slide 52. When the seat 2 moves along the first moving track, the sliding member 53 slides in the base slide 52 to form the first guide track, and the seat 2 rotates circumferentially relative to the base 1. When the seat 2 moves along the second moving track, the sliding member 53 slides in the base slide 52 to form the second guide track, and the seat 2 rotates circumferentially relative to the base 1. The base slide groove 52 extends in the left and right directions, and the base slide groove 52 is symmetrically arranged relative to the first central axis M1 of the base 1. When the seat 2 is placed in the first position, the sliding member 53 is placed in the middle position of the base slide groove 52. When the seat 2 moves from the first position to the second position, the sliding member 53 slides toward one end of the base slide groove 52. When the seat 2 moves from the first position to the third position, the sliding member 53 slides toward the other end of the base slide groove 52.

[0176] Optionally, a slider 53 is provided on the seat 2, and a base slot 52 is provided on the base 1. The seat 2 is rotatably connected to the slider 53. The base 1 is provided with a support member 3, and the base slot 52 is provided on the support member 3. The slider 53 is an I-shaped structure, with both ends of the slider 53 slidably connected to the base slot 52 and the middle portion of the slider 53 rotatably connected to the seat 2.

[0177] The support member 3 is disc-shaped and can rotate on the base 1 around the base axis a extending in the up-down direction, so that the support member 3 rotates 180° or 360° as a whole so that the seat 2 can switch between the forward positive direction and the backward negative direction. The center of the third slide groove 43 and the fourth slide groove 44 also deviate from the center of the support member 3.

[0178] The sliding fitting portion is a base slide groove 52 provided on the base, and the sliding member 53 slides along the base slide groove 52; the first shaft 4 and the second shaft 5 are provided beside the base slide groove 52;

[0179] When the seat 2 moves from the first position to the second position, the sliding member 53 and the first shaft 4 first approach each other and then move away from each other;

[0180] When the seat 2 moves from the first position to the third position, the sliding member 53 and the second shaft 5 first move closer to each other and then move away from each other.

[0181] The sliding member 53 is a pin slidably disposed in the base sliding groove 52 or the sliding member 53 is a slider slidably disposed in the base sliding groove 52 .

[0182] The ratio of the length to the width of the base sliding groove 52 is greater than 2.5.

[0183] As shown in Figures 28-29, one of the seat 2 and the base 1 is provided with a sliding shaft 54, and the other of the seat 2 and the base 1 is provided with a sliding groove 55. The sliding shaft 54 ​​is slidably set in the sliding groove 55. When the seat 2 moves from the first position to the second position, one end of the sliding groove 55 is used to limit the rotation angle of the seat. When the seat 2 moves from the first position to the third position, the other end of the sliding groove 55 is used to limit the rotation angle of the seat 2.

[0184] As shown in Figures 28-29, the sliding groove 55 is a semicircular groove. In the first position, the sliding groove 55 is symmetrically arranged relative to the first central axis of the base 1, and the sliding shaft 54 ​​is placed in the middle of the sliding groove 55. When the seat is placed in the second position, the sliding shaft 54 ​​is placed at one end of the sliding groove 55. When the seat 2 is placed in the third position, the sliding shaft 54 ​​is placed at the other end of the sliding groove 55.

[0185] The base 1 is provided with a base body and a support member 3 provided on the base body. The seat 2 includes a load-bearing body and a load-bearing member 20. The load-bearing member 20 is provided between the support member 3 and the load-bearing body and is used to engage with the load-bearing body.

[0186] The first shaft 4 and the second shaft 5 are provided on the support member 3 , the third sliding groove 43 and the fourth sliding groove 44 are provided on the side of the bearing member 3 away from the bearing body; and the sliding fitting portion is provided on the support member 3 .

Figure 35 is a state diagram of the process of the seat 2 moving from the first position to the third position, and Figure 36 is a state diagram of the seat 2 placed in the third position. In other embodiments, as shown in Figures 32 to 36, the first moving trajectory and the second moving trajectory are not arranged to intersect, and the seat 2 is always located in the same plane when moving along the first moving trajectory and along the second moving trajectory. As an optional method, the above-mentioned first moving trajectory and the second moving trajectory are located in the same horizontal plane.

[0188] As shown in FIGS. 36 and 37, the base 1 has a base axis a, the seat 2 has a second central axis M2 extending longitudinally along the seat 2 and an axis b perpendicular to and intersecting the second central axis M2, the axis b is parallel to the base axis a. When the seat 2 is in the first position, the axis b coincides with the base axis a. When the seat 2 is in the second position, the base axis a intersects the second central axis M2, and the distance L between the base axis a and the axis b is greater than 0, for example, 50 mm < L < 250 mm. When the seat 2 is placed in the second or third position, the seat 2 does not displace in the front-rear direction and extends a distance of L in the left or right direction. When the user places a child on the seat 2 or takes the child off the seat 2, there is no need to bend down or reach into the vehicle, which is more convenient to use.

[0189] The actuating structure includes a first shaft 4 and a second shaft 5 provided on one of the seat 2 and the base 1. When the seat 2 moves along the first movement track, the axial direction of the first shaft 4 is fixed and it rotates circumferentially relative to the seat 2 or the base 1, and the seat 2 moves along the first movement track. When the seat 2 moves along the second movement track, the axial direction of the second shaft 5 is fixed and it rotates circumferentially relative to the seat 2 or the base 1, and the seat 2 moves along the second movement track. The first shaft 4 and the second shaft 5 are provided on the seat 2, and are specifically provided on the carrier 20 of the seat 2. The base 1 has a first central axis M1 extending longitudinally. When the seat 2 is placed in the first position, the axis lines of the first shaft 4 and the second shaft 5 at the first position are symmetrically distributed on both sides of the first central axis M1 of the base 1 and close to the front end of the base 1.

[0190] The actuating structure further includes a first sliding groove 31 and a second sliding groove 32 respectively arranged opposite to the first shaft 4 and the second shaft 5. The first sliding groove 31 and the second sliding groove 32 are provided on the other of the seat 2 and the base 1 and extend in an arc shape, and the two first sliding grooves 31 and the second sliding groove 32 are not arranged in a crossed manner, so that the first shaft 4 or the second shaft 5 can drive the seat 2 to move in the first sliding groove 31 and the second sliding groove 32, and the centers of the first sliding groove 31 and the second sliding groove 32 deviate from the first central axis M1 of the base 1. Here, a support member 3 is provided on the base 1, the first sliding groove 31 and the second sliding groove 32 are provided on the support member 3, the first movement track coincides with or partially coincides with the first sliding groove 31, and the starting point and the ending point of the first movement track are respectively the two ends of the first sliding groove 31; the second movement track coincides with or partially coincides with the second sliding groove 32, and the starting point and the ending point of the second movement track are respectively the two ends of the second sliding groove 32. The support member 3 is disc-shaped, and the support member 3 can rotate on the base 1 around the base axis a extending in the up-down direction, so that the whole support member 3 rotates 180° or 360° to enable the seat 2 to switch between the forward positive direction and the backward reverse direction. The centers of the above-mentioned first sliding groove 31 and second sliding groove 32 also deviate from the center of the support member 3.

[0191] In other embodiments, the first shaft 4 and the second shaft 5 may be disposed on the base 1 , and the first sliding groove 31 and the second sliding groove 32 may be disposed on the seat 2 .

[0192] When the seat 2 moves from the first position to the second position, the sliding member slides toward the first end of the sliding engagement portion, and the first shaft 4 slides along the first slide groove 31. As shown in FIG35 , the sliding member is a guide shaft 51 provided on the carrier 20, and the sliding engagement portion is a base slide groove 52 provided on the support member 3. The guide shaft 51 slides in the base slide groove 52.

[0193] When the seat 2 moves from the first position to the third position, the sliding member slides toward the second end of the sliding fitting portion, and the second shaft 5 slides along the second sliding groove 32 .

[0194] As shown in Figures 32-36, the first slide groove 31 is extended as a whole along a direction obliquely intersecting with the base slide groove 52, and the second slide groove 32 is extended as a whole along a direction obliquely intersecting with the base slide groove 52. The first slide groove 31 and the second slide groove 32 are symmetrically arranged in the left and right directions; the base slide groove 52, the first slide groove 31 and the second slide groove 32 are connected to each other.

[0195] As shown in Figures 32-36, the base 1 is further provided with a first avoidance groove 45 and a second avoidance groove 46. One end of the first avoidance groove 45 is connected to the first chute 31, and one end of the second avoidance groove 46 is connected to the second chute 32. The first avoidance groove 46 and the second avoidance groove 46 are both connected to the base chute 52.

[0196] As shown in Figures 32-36, the first chute 31 and the second chute 32 are located on the same side of the base chute 52, the first avoidance groove 45 and the second avoidance groove 46 are located on the same side of the base chute 52, and the first chute 31 and the second avoidance groove 46 are located on both sides of the base chute;

[0197] When the first shaft 4 slides along the first sliding groove 31 , the second shaft 5 slides along the second avoidance groove 46 . When the second shaft 5 slides along the second sliding groove 32 , the first shaft 4 slides along the first avoidance groove 45 .

[0198] The first shaft 4 and the second shaft 5 are provided on the bearing member 20 , the first sliding groove 31 and the second sliding groove 32 are provided on the support member 3 , the sliding member is provided on the bearing member 20 , and the sliding fitting portion is provided on the support member 3 .

[0199] A first clearance groove 45 and a second clearance groove 46 are provided on the other of the seat 2 and the base 1. When the seat 2 moves along the first trajectory, the second clearance groove 46 is used for clearance, while when the seat 2 moves along the second trajectory, the first clearance groove 45 is used for clearance. Specifically, the first clearance groove 45 is used to clear the second shaft 5, while the second clearance groove 46 is used to clear the first shaft 4. The shape of the first clearance groove 45 is determined based on the second trajectory, while the shape of the second clearance groove 46 is determined based on the first trajectory.

[0200] One end of the first avoidance groove 45 is connected to the first movement trajectory, that is, the first avoidance groove 45 is connected to the first slide groove 31 forming the first movement trajectory. One end of the second avoidance groove 46 is connected to the second movement trajectory, that is, the second avoidance groove 46 is connected to the first slide groove 32 forming the second movement trajectory. The first avoidance groove 45 and the second avoidance groove 46 are arranged in an intersecting manner. The other end of the second avoidance groove 46 is used to limit the rotation angle of the seat 2 when moving from the first position to the second position, and the other end of the first avoidance groove 45 is used to limit the rotation angle of the seat 2 when moving from the first position to the third position. The seat 2 rotates 90 degrees when moving from the first position to the second position or the third position.

[0201] As shown in Figures 36 to 39, when the seat 2 moves from the first position to the second position, a first guide track is formed. When the seat 2 moves from the first position to the third position, a second guide track is formed. The first guide track and the second guide track are symmetrically arranged. Since the third position is symmetrically arranged with the second position, the first guide track and the second guide track are symmetrically arranged, ensuring that the seat 2 can move smoothly and stably to the second position or the third position. Optionally, the first guide track and the second guide track are symmetrically arranged with respect to the first central axis of the base 1, so that the position states of the seat 2 in the second position and the third position are symmetrical with respect to the first central axis of the base 1.

[0202] The first guide track and the second guide track are both straight lines, and the first guide track is connected to the second guide track. The first guide track and the second guide track are both independent motion tracks, that is, the first guide track does not intersect with the first moving track, and the second guide track does not intersect with the second moving track. Optionally, a guide shaft 51 is provided on one of the seat 2 and the base 1. When the seat 2 moves along the first moving track, the guide shaft 51 is axially fixed and rotates circumferentially relative to the seat 2 or the base 1 to form the first guide track. When the seat 2 moves along the second moving track, the guide shaft 51 is axially fixed and rotates circumferentially relative to the seat 2 or the base 1 to form the second guide track.

[0203] A first base chute and a second base chute are provided on the other of the seat 2 and the base 1. The first base chute and the second base chute are connected to form a base chute 52, and the guide shaft 51 can slide within the first and second base chute. When the seat 2 is in the first position, the first and second base chute are symmetrically arranged relative to the first central axis M1 of the base 1, that is, the first and second base chute extend in the left-right direction. The first base chute, the second base chute, the first avoidance groove 45, and the second avoidance groove 46 are arranged at an intersection. The intersection is preferably located at the center of the base 1, that is, the base axis a of the base 1 coincides with the intersection. Optionally, the two first chute 31 and the second chute 32 are located on the side of the base chute 52 near the front, and the first avoidance groove 45 and the second avoidance groove 46 extend toward the rear of the base chute 52. When the seat 2 moves from the first position to the second position, the first shaft 4 slides in one of the first slots 31, and the second shaft 5 slides in the second avoidance slot 46, forming a first movement trajectory for the seat 2. The guide shaft 51 slides in the first base slot and abuts the end of the first base slot. The first base slot defines the length of the seat 2 that can be extended, and the second avoidance slot 46 defines the rotation angle of the seat 2. When the seat 2 moves from the first position to the third position, the second shaft 5 slides in the other second slot 32, and the first shaft 4 slides in the first avoidance slot 45, forming a second movement trajectory for the seat 2. The guide shaft 51 slides in the second base slot and abuts the end of the first base slot. The second base slot defines the length of the seat 2 that can be extended, and the first avoidance slot 45 defines the rotation angle of the seat 2.

[0204] Figures 40-47 show a safety seat according to embodiment 5 of the present invention, which includes a base 1, a supporting member 20 and an actuating structure. The base 1 is configured to be mounted on a car seat. The supporting member 22 is rotatably connected to the base 1 via a rotating shaft 10; a seat mounting structure 21 is provided on the supporting member 20 for mounting the supporting body. In this embodiment, the supporting body can specifically be a safety seat 22 suitable for use by older children, or a carrier 21 suitable for use by younger infants. The actuating structure includes a swinging member 9 and a base slide 52, one end of the swinging member 9 being rotatably connected to the base 1, and the other end being rotatably connected to the supporting member 20; the rotating shaft 10 is slidably engaged with the base slide 52. In this embodiment, the rotating shaft 10 can be disposed on the support member 20, and the base chute 52 can be disposed on the base 1; or the rotating shaft 10 can be disposed on the base 1, and the base chute 52 can be disposed on the support member 20. As long as the rotating shaft 10 can slide along the base chute 52, thereby enabling the support member 20 to move laterally relative to the base 1, it is sufficient. In this embodiment, the position at which the swinging member 9 is rotatably connected to the base 1 should be staggered from the position at which the rotating shaft 10 is located. In other words, the position at which the swinging member 9 is rotatably connected to the base 1 cannot be located at the rotation center of the support member 20. This is to prevent the swinging member 9 and the support member 20 from rotating about the same center of a circle when the support member 20 is rotated, thereby preventing the rotating shaft 10 from sliding laterally. Therefore, in this embodiment, the position at which the swinging member 9 is rotatably connected to the base 1 is staggered from the position at which the rotating shaft 10 is located. This allows the swinging member 9 to cause the rotating shaft 10 to slide along the base chute 52 when the support member 20 rotates relative to the base 1.

[0205] The safety seat provided in this embodiment utilizes an actuating structure to allow the support member 20 to shift laterally during rotation relative to the base 1. This allows the support member 20 to extend the supporting body thereon a certain distance outward relative to the base 1, making it easier for users to lift a child onto or off the supporting body without having to bend over or reach into the car to operate. The actuating structure includes a swinging member 9 and a base chute 52. The swinging member 9 causes the support member 20 to shift laterally, resulting in a simple structure and reliable use. The base chute 52 slides in conjunction with the rotating shaft 10 to guide the lateral shift of the support member 20, ensuring smooth movement of the support member 20 relative to the base 1 and enhancing passenger comfort.

[0206] In this embodiment, the carrier 20 is movable between a first position and a second position. When the carrier 20 is in the first position, it is oriented in a first direction. When the carrier 22 is moved to the second position via the actuating structure, the central axis of the carrier 20 deviates from the central axis of the carrier 20 in the first position, and the carrier 20 is oriented in a second direction different from the first direction. Specifically, the first position is the position in which a child normally sits in the vehicle, while the second position is the position in which the carrier 20 is extended to one side, allowing a parent to lift a child onto or off the vehicle body. In this embodiment, the first direction is perpendicular to the second direction. This arrangement allows the carrier 20 to extend toward one side of the vehicle body during a 90-degree rotation, making operation more convenient for the user and ensuring that the extended carrier body faces the outside of the vehicle body. Furthermore, the first direction is forward or rearward, allowing children to face forward or rearward when seated in the safety seat, improving ride comfort and making it easier for parents to care for their children. The second direction is leftward or rightward, facing the left or right door of the car. This allows the support body 20 to be closer to the car's door frame when extended, or even partially extend beyond the door frame, making it easier for parents to place and restrain their children in the support body. Exemplarily, when the support body 20 rotates 90 degrees to the left or right, the center of the support body shifts 170 mm to the left or right, making it easier for users to lift and lower children into and out of the safety seat. Accordingly, the base chute 52 of this embodiment extends in the left-right direction to ensure smooth leftward or rightward shifting of the support body 20 during rotation. Exemplarily, the base chute 52 is located at the top of the base 1, and the rotation axis 10 is located at the center of the support body 20.

[0207] Furthermore, the carrier 20 has a third position, symmetrically arranged with the second position. The orientation of the carrier 20 in the second position is opposite to that of the carrier 22 in the third position. Specifically, the second position can be where the carrier 20 is offset and extended to the left, while the third position can be where the carrier 20 is offset and extended to the right. When the carrier 20 is in the second position, the front of the carrier body faces the left side of the vehicle, while when the carrier 20 is in the third position, the front of the carrier body faces the right side of the vehicle. This arrangement allows the carrier 20 to be offset both left and right, making it convenient for users to select either the second or third position based on the safety seat's installation position on the vehicle seat, with the carrier body facing the corresponding vehicle door.

[0208] In this embodiment, the swinging member 9 can be a rocker, a connecting rod, or a connecting piece, as long as its ends are rotatably connected to the base 1 and the supporting member 20, respectively, and can swing with the rotation of the supporting member 20. For example, in this embodiment, the swinging member 9 is a rocker, which has a simple structure and is easy to install. Furthermore, one end of the rocker is pivotally connected to the supporting member 20 via a first rocker axis 91, and the other end is pivotally connected to the base 1 via a second rocker axis 92. When the supporting member 20 is in the first position, the line connecting the first rocker axis 91 and the rotation axis 10 extends in the front-to-back direction; when the supporting member 20 is in the second position, the line connecting the first rocker axis 91 and the rotation axis 10 extends in the left-to-right direction. This arrangement ensures that when the supporting member 20 is switched to the first or second position, the line connecting the first rocker axis 91 and the rotation axis 10 is parallel to the longitudinal centerline of the supporting member 20, resulting in a stable structure and reliable operation. Specifically, when the support member 20 is in the first position, the first axis 91 of the rocker arm is located directly behind the support member 20 and is relatively close to the edge of the support member 20. This makes it easier for the rocker arm to pull the support member 20, resulting in smoother operation. Furthermore, when the support member 20 is in the first position, the distance between the second axis 92 of the rocker arm and the first axis 91 of the rocker arm is approximately equal to the distance between the second axis 92 of the rocker arm and the rotation axis 10, thereby ensuring that the support member 20 deviates to one side during a 90-degree rotation and improving structural stability. Optionally, a clearance groove 33 is also provided on the base 1. As the rocker arm rotates around the second axis 92 of the rocker arm, the first axis 91 of the rocker arm can slide along the clearance groove 33. This rational structure ensures that the rocker arm rotates smoothly. Specifically, the clearance groove 33 is arc-shaped, and the radius of the arc is equal to the length of the rocker arm.

[0209] Optionally, the actuating structure further includes a sliding member 53, which is slidably disposed in the base chute 52, and the carrier 20 is rotatably connected to the sliding member 53 via the rotating shaft 10. By providing the sliding member 53, the connection between the carrier 22 and the base 1 is made more reliable, and the stability of the rotation and sliding of the carrier 20 is improved. Specifically, the sliding member 53 of this embodiment is "H"-shaped, with its two sides slidingly engaged with the base chute 52, and an axial hole 532 provided in the middle for connecting to the rotating shaft 10 on the carrier 20. Furthermore, the safety seat also has a stroke limiting structure for limiting the rotation angle of the carrier 20. The stroke limiting structure includes a first abutment portion provided on the sliding member 53 and a second abutment portion provided on the carrier 20. When the carrier 20 moves to the second position, the second abutment portion abuts against the first abutment portion, thereby limiting the carrier 20 from continuing to rotate in the same direction. The above arrangement prevents the support member 20 from rotating further after it has rotated to the second position, allowing the support member 20 to face the left or right side of the vehicle body at this point, making it easier for children to get in and out of the safety seat and improving the stability of the support member 20 in this position. Optionally, in this embodiment, the sliding member 53 is provided with an arcuate groove 531, with the first abutment portions provided on the inner walls of the two ends of the arcuate groove 531, and the second abutment portions include guide posts 23 provided on the support member 20. When the support member 20 rotates between the first and second positions, the guide posts 23 slide along the arcuate groove 531. When the guide posts 23 move to abut against the two ends of the arcuate groove 531, the support member 20 cannot rotate further. Specifically, the arcuate groove 531 is in the shape of a circular arc, with the shaft hole 532 as its center and the distance between the rotating shaft 10 and the guide posts 23 as its radius. This allows for smooth rotation of the support member 20 relative to the sliding member 53 and limits the position of the support member 20.

[0210] Optionally, the base 1 of this embodiment includes a base body 11 and a support member 3 disposed on the base body 11. The base body 11 is configured to be mounted and fixed to the car seat, and the support member 3 is configured to be connected to the carrier 20. Specifically, the carrier 20 is rotatably connected to the support member 3 via a rotating shaft 10. A base chute 52 is disposed on the upper portion of the support member 3, and the rotating shaft 10 is slidably connected within the base chute 52. One end of the swing member 9 is rotatably connected to the support member 3, and the other end is rotatably connected to the carrier 20. Furthermore, the support member 3 of this embodiment is disc-shaped and rotatably disposed within the base body 11. The support member 3 can rotate 180° or 360° about a centerline extending in the vertical direction within the base body 11, enabling the carrier to switch between a forward-facing orientation and a rearward-facing orientation, and allowing for flexible adjustment of the carrier's placement angle. Furthermore, the safety seat may also include a locking mechanism that locks the support member 3 after it has rotated to a desired angle.

[0211] 48-50 show a safety seat according to a sixth embodiment of the present invention. The structure of the safety seat is substantially the same as that of the safety seat according to the fifth embodiment, with the main differences being:

[0212] The safety seat of this embodiment is not provided with a sliding member 53 , an avoidance groove 33 and a travel limiting structure.

[0213] In this embodiment, one end of the rotating shaft 10 is mounted on the support member 20, while the other end is rotatably mounted within the base chute 52 and can slide along the base chute 52. This arrangement simplifies the safety seat structure and facilitates installation, thereby reducing manufacturing costs. Of course, to improve the smooth movement of the rotating shaft 10 within the base chute 52, a slider can also be provided within the base chute 52. The lower end of the rotating shaft 10 is rotatably connected to the slider, which is then slidably connected within the base chute 52.

[0214] This embodiment can also achieve that the supporting member 20 is offset to one side while rotating, thereby extending outward relative to the base 1. When placing the child on the supporting body, the user does not need to bend over or stretch the body into the car to operate, which is convenient to use and reduces bumps.

[0215] As shown in Figures 51 to 59, a safety seat according to embodiment 7 of the present invention is shown. The safety seat of this embodiment includes a base frame 100, a rotating frame 200, and an actuating mechanism 300. A seat mounting structure is provided on the rotating frame 200, and the seat mounting structure is used to mount a seat so that the seat can move together with the rotating frame 200. Exemplarily, the base frame 100 is mounted on the rear seat of the vehicle, for example, the base frame 100 is detachably connected to the rear seat. Exemplarily, the base frame 100 can be directly connected to the rear seat, or can be connected to the rear seat through other structures, for example, the base frame 100 is connected to the rear seat through a base 500.

[0216] It should be noted that after the base frame 100 is connected to the rear seat, its position relative to the rear seat in the length and width directions of the vehicle cannot be adjusted, that is, the base frame 100 cannot be moved in the length and width directions of the vehicle.

[0217] The rotating frame 200 is movably disposed above the base frame 100. The rotating frame 200 can rotate and translate relative to the base frame 100 under the action of an external force, so that the seat on the rotating frame 200 can be moved from a position inside the vehicle to a position extending outside the vehicle, or to a position closer to the vehicle door, making it easier to place a child on the seat or to lift a child out of the seat.

[0218] Exemplarily, the actuating mechanism 300 includes a rotating disk 320 disposed on the rotating frame 200 and an actuating guide 310 disposed on the base frame 100. The rotating disk 320 is rotatable relative to the base frame 100. In this embodiment, the rotating disk 320 is disposed on the side of the rotating frame 200 facing the base frame 100, and the actuating guide 310 is disposed on the side of the base frame 100 facing the rotating frame 200.

[0219] When the rotating frame 200 rotates under the action of an external force, the rotating disk 320 can rotate synchronously. Furthermore, the rotating disk 320 simultaneously rolls along the actuating guide 310 during rotation, causing the center of the rotating disk 320 to move along the preset direction X. This in turn drives the rotating frame 200 to move in the preset direction X, thereby enabling the seat on the rotating frame 200 to move from a position inside the vehicle to a position extending outside the vehicle or closer to the vehicle door. For example, for vehicle-mounted safety seats, the preset direction X is the left-right direction of the vehicle. The guidance of the actuating guide 310 ensures that the rotating disk 320 and the rotating frame 200 can move along the preset direction X.

[0220] The safety seat provided in this embodiment includes an actuating mechanism 300 including a rotating disk 320 disposed on the rotating frame 200 and an actuating guide 310 disposed on the base frame 100. When the rotating frame 200 rotates, the rotating frame 200 drives the rotating disk 320 to rotate synchronously. While rotating, the rotating disk 320 simultaneously rolls along the actuating guide 310 so that the center of the rotating disk 320 moves along a preset direction X, thereby driving the rotating frame 200 to move a certain distance in the preset direction X while rotating. That is, the rotation and translation of the rotating frame 200 are performed simultaneously and continuously, thereby improving the speed and efficiency of adjusting the position of the rotating frame 200 and facilitating operation.

[0221] Furthermore, the user can move the rotating frame 200 closer or further away as needed, providing greater flexibility. For example, the user can push the rotating frame 200 to move at least partially the seat on the rotating frame 200 outside the vehicle or closer to the vehicle door, allowing the child in the seat to be closer to the user. This facilitates operations such as adjusting the child's seating space, facilitating the user's ability to lift the child, or facilitating interactive play between the child and the user. Furthermore, the user can reduce the amount of bending required to place the child in the seat or lift the child out of the seat, providing greater ease of use.

[0222] Optionally, the actuating guide 310 extends along a preset direction X, and both ends of the actuating guide 310 in the preset direction X are flush with or within the edge of the base frame 100 to prevent the setting of the actuating guide 310 from increasing the overall volume of the safety seat.

[0223] For example, the edge of the actuating guide 310 facing away from the rotating disk 320 extends to the edge of the base 100 so as to fill part of the gap between the base 100 and the rotating frame 200 and reduce the chance of dust accumulation. In addition, the actuating guide 310 can also provide a certain amount of support for the rotating frame 200 in the vertical direction (i.e., the axial direction of the rotating disk 320). The rotating frame 200 is supported by the rotating disk 320 and the actuating guide 310, so that the rotating frame 200 can be relatively stable, reducing the chance of shaking of the rotating frame 200 and the seat.

[0224] Exemplarily, the rotating frame 200 switches between a first position and a second position, that is, the rotating frame 200 has a first position and a second position relative to the base frame 100. The rotating frame 200 moves between the first position and the second position under the action of an external force.

[0225] For example, when the rotating frame 200 is in the first position, the rotating frame 200 is oriented in a first direction. When the rotating frame 200 is moved to the second position via the actuating mechanism 300, the central axis of the rotating frame 200 deviates from the central axis of the rotating frame 200 in the first position, and the rotating frame 200 is oriented in a second direction different from the first direction. The first direction and the second direction may be arranged at an angle, or the first direction and the second direction may be arranged perpendicularly, which is not limited in this embodiment.

[0226] In this embodiment, the first and second positions of the rotating frame 200 are not limited. The first and second positions can be set according to the angle adjustment range required by the rotating frame 200 or the seat. Figures 51 and 54 are schematic diagrams of the rotating frame 200 in the first position, Figure 56 is a schematic diagram of the rotating frame 200 in the second position, and Figure 55 is a state diagram of the rotating frame 200 moving from the first position to the second position. For example, in the examples of Figures 54 and 56, when the rotating frame 200 is in the first position, the rotating frame 200 is positioned toward the front or rear of the vehicle, facilitating the safety seat to protect the child while the vehicle is moving; when the rotating frame 200 is in the second position, the rotating frame 200 is positioned toward the side of the vehicle, allowing the child to be closer to the user.

[0227] Optionally, the safety seat further includes a limiting structure (not shown), which is provided on one of the rotating frame 200 and the base frame 100. When the rotating frame 200 is in the second position, the limiting structure contacts the other of the rotating frame 200 and the base frame 100 to limit the travel of the rotating frame 200, so that the rotating frame 200 can be exactly located in the second position and prevent excessive movement of the rotating frame 200. For example, the limiting structure can be a limiting block.

[0228] It should be noted that when the rotating frame 200 is in the first position, a stop structure may be provided to limit the further movement of the rotating frame 200. Of course, when the rotating frame 200 is in the first position, a stop structure may not be provided, and this embodiment does not limit this.

[0229] For example, when the rotating frame 200 rotates from the first position to the second position, the rotating disk 320 rolls along the actuating guide 310 for a distance equal to one-quarter of the circumference of the rotating disk 320. That is, the rotating frame 200 reaches the second position after rotating 1 / 4 of a turn from the first position. This arrangement reduces the number of rotations of the rotating frame 200 and the rotating disk 320 to less than one turn, further improving the speed and efficiency of the rotating frame 200 when moving from the first position to the second position.

[0230] Of course, it is understandable that the rotating frame 200 and the rotating disk 320 can also rotate by an integral multiple of 1 / 4 circle and can also move from the first position to the second position, which is not limited in this embodiment.

[0231] In some optional embodiments, the rotating frame 200 further has a third position symmetrically arranged with respect to the second position. The rotating frame 200 can be moved from the first position to the third position via the actuating mechanism 300. The orientation of the rotating frame 200 when in the second position is opposite to the orientation when in the third position. Figure 58 is a schematic diagram of the rotating frame 200 in the third position. Figure 57 is a state diagram of the rotating frame 200 moving from the first position to the third position. By enabling the rotating frame 200 to move to the third position, the rotating frame 200 can be moved in both the second direction and the direction opposite to the second direction. In this way, the safety seat can be placed on the rear seat of the vehicle near the left door or the rear seat of the vehicle near the right door, both achieving the purpose of being closer to the user. This provides high flexibility and versatility, meeting the needs of different application scenarios.

[0232] It should be noted that the orientation of the rotating frame 200 when in the second position is opposite to the orientation of the rotating frame 200 when in the third position. The rotation direction of the rotating disk 320 when the rotating frame 200 moves from the first position to the second position is opposite to the rotation direction of the rotating disk 320 when the rotating frame 200 moves from the first position to the third position. R1 in FIG. 55 indicates the rotation direction of the rotating frame 200 when moving from the first position to the second position, and R2 in FIG. 57 indicates the rotation direction of the rotating frame 200 when moving from the first position to the third position. R1 and R2 are opposite.

[0233] Exemplarily, when the rotating frame 200 rotates from the first position to the third position, the rotating disk 320 rolls along the actuating guide 310 for a length equal to one quarter of the circumference of the rotating disk 320 , that is, the rotating frame 200 reaches the third position after rotating 1 / 4 of a circle from the first position.

[0234] For example, the rotating frame 200 can continuously move from the second position to the first position and then to the third position. At this time, the length of the rotating disk 320 rolling along the actuating guide 310 is equal to half of the circumference of the rotating disk 320 .

[0235] Exemplarily, the rotating frame 200 switches between a first position and a second position.

[0236] When the rotating frame 200 is in the first position, as shown in FIG54 , the orthographic projection of the rotating frame 200 in the axial direction coincides with the orthographic projection of the base frame 100 in the axial direction. By aligning the rotating frame 200 and the base frame 100 in the first position, the safety seat has a more regular shape and does not occupy a large space. This also facilitates mass production of the rotating frame 200 and the base frame 100.

[0237] When the rotating frame 200 is in the second position, the line connecting the center of the rotating frame 200 and the center of the base frame 100 extends along the preset direction X. Similarly, when the rotating frame 200 is in the third position, the line connecting the center of the rotating frame 200 and the center of the base frame 100 extends along the preset direction X. This allows the rotating frame 200 to be located directly to the left or right of the base frame 100, reducing the space required for the front and rear directions of the vehicle after the rotating frame 200 rotates, and providing better adaptability. It should be noted that the center of the rotating frame 200 is the geometric center of the cross section of the rotating frame 200, and the center of the base frame 100 is the geometric center of the cross section of the base frame 100. When both the rotating frame 200 and the base frame 100 are disc structures, the center is the center of the circle.

[0238] Optionally, as shown in FIG55 , the actuating guide 310 extends in a direction parallel to the preset direction X, and when the rotating frame 200 is in the first position, the center of the rotating disk 320 is located on the centerline of the actuating guide 310. Specifically, the center of the rotating disk 320 is located on the centerline of the actuating guide 310 perpendicular to the preset direction X. The rotating disk 320 can roll toward both ends of the actuating guide 310 in the preset direction X to move the rotating frame 200 to the second and third positions, respectively. For example, when the rotating disk 320 rolls toward one end of the actuating guide 310, the rotating frame 200 moves to the second position; when the rotating disk 320 rolls toward the other end of the actuating guide 310, the rotating frame 200 moves to the third position.

[0239] For example, as shown in FIG52 , the actuating mechanism 300 further includes an auxiliary guide structure 400 , which is used to limit the center of the rotating disk 320 from moving in a predetermined direction X, thereby ensuring that the rotating disk 320 and the rotating frame 200 can move in the predetermined direction X. For example, the auxiliary guide structure 400 can limit the distance between the center of the rotating disk 320 and the actuating guide 310 to always be equal to the radius of the rotating disk 320 , thereby preventing the rotating disk 320 from moving away from the actuating guide 310 during rotation, thereby ensuring that the rotating disk 320 and the actuating guide 310 are always in contact.

[0240] Optionally, the auxiliary guide structure 400 includes a guide groove 420 and a guide rotation shaft 410. One of the guide groove 420 and the guide rotation shaft 410 is provided on the rotating disk 320, and the other is provided on the base frame 100. The guide rotation shaft 410 is disposed opposite the guide groove 420. For example, the guide rotation shaft 410 may be at least partially located in the guide groove 420. Furthermore, the guide rotation shaft 410 is slidably disposed along the extension direction of the guide groove 420 to achieve positioning of the guide groove 420 on the guide rotation shaft 410, allowing the rotating disk 320 and the rotating frame 200 to move along a predetermined direction X. The coordination between the guide groove 420 and the guide rotation shaft 410 simplifies the specific structure of the auxiliary guide structure 400, facilitates manufacturing, and reduces costs.

[0241] Further, please continue to refer to Figure 52. The guide rotating shaft 410 is arranged at the center of the rotating disk 320, that is, the guide rotating shaft 410 is arranged coaxially with the rotating disk 320. For example, the guide rotating shaft 410 can be arranged through the rotating disk 320, or the guide rotating shaft 410 can also be arranged only on the side of the rotating disk 320 facing the base frame 100, which is not limited in this embodiment. The guide groove 420 is arranged on the base frame 100. For example, the guide groove 420 can pass through the base frame 100 in the thickness direction of the base frame 100 or not, which is not limited in this embodiment. The guide groove 420 extends along a preset direction X. When the rotating disk 320 rolls along the actuating guide member 310, the guide rotating shaft 410 rotates within the guide groove 420 or rolls along the groove wall of the guide groove 420. By arranging the guide groove 420 to extend along the preset direction X, the processing and manufacturing of the guide groove 420 is facilitated.

[0242] Alternatively, the guide rotation shaft 410 is disposed on the base frame 100, specifically on a side of the base frame 100 facing the rotating disk 320. A guide groove 420 is disposed on the rotating disk 320, and the guide groove 420 is in the shape of an arc that curves toward the center of the rotating disk 320. The guide rotation shaft 410 is slidably disposed along the extending direction of the arc-shaped guide groove 420 to ensure that the rotating disk 320 and the rotating frame 200 can move in a preset direction X.

[0243] In summary, the above two configurations of the guide groove 420 and the guide rotating shaft 410 can both achieve the purpose of preventing the rotating shaft from moving in a direction away from the actuating guide member 310 , and both have high reliability.

[0244] Optionally, the length of the guide groove 420 in this embodiment is configured as follows: when the rotating frame 200 is in the second position, the guide rotating shaft 410 contacts a groove wall of the guide groove 420 in the preset direction X to limit the movement limit of the rotating disk 320 and the rotating frame 200 in the rotation direction R1. The groove wall of the guide groove 420 is used as a limiting structure, which improves the utilization rate of the guide groove 420 and eliminates the need for an additional limiting structure, thereby simplifying the overall structure of the safety seat.

[0245] Similarly, the length of the guide groove 420 is further configured such that when the rotating frame 200 is located at the third position, the guide rotation shaft 410 contacts another groove wall of the guide groove 420 in the preset direction X, thereby limiting the movement limit of the rotating disk 320 and the rotating frame 200 in the rotation direction R2.

[0246] In some optional embodiments, the rotating disk 320 is a toothed disk having an overall circular outer contour. When the auxiliary guide structure 400 includes a guide rotating shaft 410, the guide rotating shaft 410 is coaxially disposed with the toothed disk. The actuating guide 310 includes a rack 311 extending along a predetermined direction X. The toothed disk meshes with the rack 311. The rack 311 guides the rotation of the toothed disk. Furthermore, the engagement of the rack 311 with the toothed disk improves the stability of the toothed disk's rotation and movement, resulting in smoother movement of the toothed disk.

[0247] In addition, when the rotating frame 200 is located in the first position, the second position, or the third position, the rack 311 limits the gear disc in the preset direction X. That is, directly applying a force in the preset direction X to the rotating frame 200 cannot push the gear disc to move in the preset direction X relative to the rack 311. Only when the rotating frame 200 is driven to rotate can the gear disc move along the rack 311, so that the rotating frame 200 can be more stably located in the first position, the second position, or the third position, reducing the probability of the rotating frame 200 and the seat shaking, thereby improving the safety of the safety seat.

[0248] In some other optional embodiments, the rotating disk 320 is disc-shaped, and the outer peripheral surface of the rotating disk 320 is a smooth surface, and the surface of the actuating guide 310 facing the rotating disk 320 is flat. When the rotating disk 320 rolls along the actuating guide 310, the outer peripheral surface of the rotating disk 320 is in frictional contact with the surface of the actuating guide 310 facing the rotating disk 320, which can also achieve the purpose of the rotating disk 320 rolling along the actuating guide 310 while rotating so that the center of the rotating disk 320 moves along the preset direction X.

[0249] Optionally, the safety seat further includes an axial locking structure (not shown in the figure), which is used to limit the movement of the rotating frame 200 relative to the base frame 100 in the axial direction of the base frame 100, thereby ensuring that the rotating frame 200 rotates relative to the base frame 100 and moves along the preset direction X smoothly.

[0250] By way of example, the specific configuration of the locking structure can be various. For example, the locking structure can be a locking block mounted on one end of the guide rotating shaft 410 that passes through the guide groove 420. The length or width of the locking block is greater than the width of the guide groove 420, so that the locking block does not pass through the guide groove 420, thereby restricting the rotating frame 200 in the axial direction of the base frame 100. As another example, the locking structure can include a dovetail groove and a dovetail block, one of which is provided on the rotating frame 200 and the other is provided on the base frame 100. The dovetail groove is arc-shaped so as not to interfere with the rotation and translation of the rotating frame 200. The dovetail block slides in conjunction with the dovetail groove to restrict the movement of the rotating frame 200 relative to the base frame 100 in the axial direction of the base frame 100.

[0251] Optionally, as shown in Figure 59, the safety seat further includes a base 500, to which the base frame 100 is rotatably connected. The base 500 is mounted on the rear seat of a vehicle, and the connection between the base 500 and the rear seat is fixed, so that the base 500 cannot rotate or translate relative to the rear seat. By rotatably connecting the base frame 100 to the base 500, the base frame 100 can be rotated 360 degrees relative to the base 500 to adjust the orientation of the base frame 100, the rotating frame 200, and the seat.

[0252] Illustratively, the central axis of the base frame 100 is parallel to or coincides with the central axis of the base 500 , and the base frame 100 can rotate relative to the base 500 with the central axis of the base frame 100 or the central axis of the base 500 as the rotation axis.

[0253] In some optional embodiments, the centers of the actuating guide 310 and the rotating disk 320 are respectively located on both sides of the central axis of the base frame 100, that is, the center of the rotating disk 320 does not coincide with the central axis of the base frame 100, and the guide groove 420 and the center of the rotating disk 320 are located on the same side of the central axis of the base frame 100.

[0254] The safety seat provided in the eighth embodiment of the present invention (not shown) differs from that in the seventh embodiment in that the specific structure of the auxiliary guide structure is different.

[0255] Specifically, in this embodiment, the rotating disk is disposed on the rotating frame, and the actuating guide member and the auxiliary guide structure are both disposed on the base frame.

[0256] In a direction perpendicular to the preset direction, the auxiliary guide structure and the actuating guide member are located on both sides of the rotating disk, so that the rotating disk is located between the auxiliary guide structure and the actuating guide member.

[0257] The auxiliary actuating guide member abuts against the rotating disk to restrict the rotating disk from moving away from the actuating guide member in a direction perpendicular to the preset direction. The rotating disk contacts both the actuating guide member and the auxiliary guide structure, enabling the actuating guide member and the auxiliary guide structure to limit the rotating disk in a direction perpendicular to the preset direction, preventing the rotating disk from moving away from the actuating guide member. This ensures that the rotating disk and rotating frame can move in the preset direction, improving structural reliability.

[0258] Furthermore, when the actuating guide member includes a rack and the rotating disk is a toothed disk, the auxiliary guide structure extends parallel to the rack, i.e., it extends in a predetermined direction. Furthermore, the auxiliary guide structure abuts the edge of the toothed disk. It should be noted that the auxiliary guide structure only contacts the toothed disk, not engages it. If the auxiliary guide structure were also toothed, the rotating disk, the auxiliary guide structure, and the rack would become stuck and unable to move. For example, the surface of the auxiliary guide structure facing the rotating disk is flat.

[0259] Illustratively, the auxiliary guide structure may be a strip structure fixedly disposed on the base frame, with both ends of the strip structure not exceeding the edge of the base frame, so as to avoid increasing the overall volume of the safety seat due to the provision of the auxiliary guide structure.

[0260] The other structures in this embodiment have similar structures and similar beneficial effects to the corresponding structures in Example 1, and this embodiment does not limit this.

[0261] The safety seat provided in the ninth embodiment of the present invention (not shown) is different from that in the seventh embodiment in that the specific structure of the auxiliary guide structure is different.

[0262] Specifically, in this embodiment, two groups of auxiliary guide structures are provided, one group of auxiliary guide structures is the auxiliary guide structure in the first embodiment, and the other group of auxiliary guide structures is the auxiliary guide structure in the second embodiment.

[0263] For example, a group of auxiliary guide structures includes a guide rotating shaft and a guide groove, one of which is arranged on the rotating disk and the other is arranged on the base frame. The guide rotating shaft and the guide groove are arranged relative to each other. For example, the guide rotating shaft can be at least partially located in the guide groove. In addition, the guide rotating shaft is slidably arranged along the extension direction of the guide groove to achieve the positioning of the guide rotating shaft by the guide groove, so that the rotating disk and the rotating frame move along the preset direction. In another group of auxiliary guide structures, the auxiliary guide structure and the actuating guide are located on both sides of the rotating disk in a direction perpendicular to the preset direction, so that the rotating disk is located between the auxiliary guide structure and the actuating guide. The auxiliary actuating guide is against the rotating disk to limit the rotating disk from moving away from the actuating guide in a direction perpendicular to the preset direction.

[0264] By providing two sets of auxiliary guide structures, the limiting effect and reliability of the moving directions of the rotating shaft and the rotating frame can be further improved, so as to ensure that the rotating shaft and the rotating frame can move in the preset direction.

[0265] Figures 61 to 63 illustrate a safety seat according to Embodiment 10 of the present invention, designed to be mounted on a vehicle seat for infants and young children. The safety seat comprises a base 1, a support member 3, a seat 2, and an actuating structure. The support member 3 is disposed above the base 1, and the seat 2 has a first position and a second position relative to the base 1. An actuating structure is disposed between the seat 2 and the support member 3, and is configured to rotate the seat 2 relative to the base 1 between the first and second positions.

[0266] When the seat 2 is rotated from the first position to the second position, the central axis of the seat 2 is offset in the first direction from the central axis c of the seat 2 when it is in the first position. In this embodiment, the first direction is the left and right direction, and the second direction is the front and back direction. In the second position, the central axis of the seat 2 is offset in the left and right directions from the central axis of the seat 2 when it is in the first position, thereby enabling the seat 2 to move laterally left and right during the rotation process, thereby better realizing the use of the safety seat and making it easier for children to sit in and be taken out of the safety seat.

[0267] The seat 2 has a seating space, which faces forward or backward when the seat 2 is in a first position, and faces left or right when the seat 2 is in a second position.

[0268] The seat 2 includes a carrier 20 and a carrier body. The carrier 20 is connected to the support member 3, and the carrier body is connected to the carrier 20. The carrier body and the carrier 20 can be integrally formed or separately formed. If the carrier body and the carrier 20 are separately formed, the two can be assembled or disassembled, and different carrier bodies can be selected according to usage needs. In this embodiment, the first movable shaft 410 and the second movable shaft 510 are both provided on the carrier 20 and located at the bottom of the carrier 20. It is understood that when the first movable shaft 410 and the second movable shaft 510 are provided on the support member 3, the first guide structure 42 and the second guide structure 520 are provided on the carrier 20 and located at the bottom of the carrier 20.

[0269] In a specific embodiment, the first guide structure 42 and the second guide structure 520 can both be grooves disposed on the carrier 20. The first guide structure 42 is a first groove, and the second guide structure 520 is a second groove. In this embodiment, the first groove and the second groove are two independent grooves, separated from each other. The first groove extends toward the second groove and reaches the edge of the second groove. This structural arrangement prevents the first movable shaft 410 and the second movable shaft 510 from interfering with each other when sliding within their respective guide structures.

[0270] The carrier can be a safety seat 22, as shown in Figures 60 and 61, suitable for older children. Figure 60 shows the safety seat 22 in the first position, facing forward, while Figure 61 shows the safety seat 22 in the second position, facing rearward. The carrier can also be an infant carrier, suitable for younger infants.

[0271] As shown in Figures 63 and 64, the seat 2 also has a third position symmetrical to the second position. The seat 2 rotates between the first position and the third position relative to the base 1 via the actuating structure. The orientation of the seat 2 when it is in the second position is opposite to the orientation of the seat 2 when it is in the third position. For example, if the orientation of the carrying space when the seat 2 is in the second position is to the left, then the orientation of the carrying space when the seat 2 is in the third position is to the right; if the orientation of the carrying space on the seat 2 when it is in the second position is to the right, then the orientation of the carrying space on the seat 2 when it is in the third position is to the left.

[0272] When the seat 2 is in the third position, the central axis c of the seat 2 is offset in a first direction relative to the central axis c of the seat 2 in the first position, and remains offset in a second direction relative to the central axis c of the seat 2 in the first position. In the third position, the seat 2 can extend outward relative to the base 1. This allows the user to place or remove a child from the seat 2 without having to bend over or reach into the vehicle, making it more convenient. Furthermore, when the seat 2 is in the third position, it does not exhibit a certain amount of fore-and-aft offset relative to the base 1, eliminating the need for the user to provide sufficient space for the safety seat to rotate.

[0273] By setting the second position and the third position, the installation position of the safety seat is not limited. That is, whether the safety seat is installed near the left door or the right door, the seat 2 can be extended outward relative to the base 1, thereby improving the flexibility of the safety seat.

[0274] As shown in Figures 63, 64 and 65, the actuating structure includes a first movable shaft 410 and a second movable shaft 510 arranged on one of the seat 2 and the support member 3, and the actuating structure also includes a first guide structure 42 and a second guide structure 520 arranged on the other of the seat 2 and the support member 3, the first movable shaft 410 is slidably arranged in the first guide structure 42, and the second movable shaft 510 is slidably arranged in the second guide structure 520.

[0275] When the seat 2 rotates from the first position to the second position, the first movable axis 410 slides along the first guide structure 42, and the second movable axis 510 slides along the second guide structure 520, and in the second position, the central axis of the seat 2 is offset in the left and right directions from the central axis of the seat 2 when it is in the first position.

[0276] The first guide structure 42 and the second guide structure 520 are both groove bodies, one of which is a sliding groove and the other is a guide groove. Through the sliding of the two grooves and the two axes, the seat 2 can achieve synchronous sliding during the rotation process, so that the seat 2 can be offset from the base 1, which can make the use of the seat 2 more convenient.

[0277] In this embodiment, the first movable shaft 410 and the second movable shaft 510 are respectively axially fixed to the seat 2 and are circumferentially rotatable relative to the seat 2 or the base 1. The first movable shaft 410 can be rotatably mounted on the seat 2 or fixed thereto. The first movable shaft 410 is directly inserted into the first guide structure 42 and can slide along the extension direction of the first guide structure 42. At the same time, the first movable shaft 410 can rotate circumferentially within the first guide structure 42. The second movable shaft 510 has the same structure as the first movable shaft 410 and will not be further elaborated here.

[0278] In this embodiment, in the first position, along the front-to-back direction, the second movable shaft 510 is relatively located close to the rear side of the support member 3 .

[0279] The second movable shaft 510 can be fixed on the seat 2 or on the base 1 . In this embodiment, the second movable shaft 510 is fixed on the seat 2 as an example for description.

[0280] Positioning the second movable axis 510 relatively close to the rear side of the seat 2 allows the seat 2 to swing about the second movable axis 510 during rotation, thereby causing the entire seat 2 to deflect more laterally during rotation. It will be appreciated that the closer the second movable axis 510 is to the center of the seat 2, the less outward deflection the seat 2 will experience during rotation. When the second movable axis 510 is located at the center of the seat 2, the seat 2 can only rotate circumferentially without lateral deflection.

[0281] It is understood that after the seat 2 is mounted and fixed on the support member 3, the second movable axis 510 is also relatively located near the rear side of the support member 3. It should be noted that the term "located near the rear side of the seat 2" here is compared with the term "located near the front side of the seat 2". The seat 2 is generally located in the area between the center of the seat 2 and the rear side of the seat.

[0282] When moving toward the second position, the second movable shaft 510 moves relatively in a direction away from the rear side of the support member 3 , and the first movable shaft 410 moves relatively in the left-right direction.

[0283] When the seat 2 moves to the second position, the second movement axis 510 is located close to the center of the support member 3 in the front-rear direction.

[0284] As the seat 2 rotates, the second movable shaft 510 moves along the second guide structure 520 and relatively forward, moving closer to the center of the seat 2. This provides better support and stability for the seat 2 when it slides sideways. This structural arrangement allows the second movable shaft 510 to move toward the center of the seat 2 as the seat 2 deflects about the second movable shaft 510, preventing the seat 2 from moving to the edge of the support member 3 after rotation, which would reduce stability.

[0285] It is understandable that in order to move the second movable axis 510 to the center position close to the front-to-back direction of the support member 3, one end of the second guide structure 520 will correspondingly extend to the center position close to the front-to-back direction of the support member 3.

[0286] It should be noted that the specific shape of the extended arrangement of the second guide structure 520 is not further limited. The overall extension shape of the second guide structure 520 can be a straight line or a curved line. Of course, in other embodiments, the extension shape of the second guide structure 520 can also be set to be a broken line. The curved second guide structure can be formed by a single arc or multiple arc segments.

[0287] In the first position, the first movable axis 410 is relatively arranged at the center position of the support member 3 in the front-to-back direction;

[0288] In the second position, the first movable axis 410 is located close to the edge of the support member 3 in the left-right direction.

[0289] In the first position, positioning the first movable shaft 410 at the center of the support member 3 in the front-to-back direction allows the seat 2 to have sufficient space when sliding along the support member 3. The area at the center of the support member 3 in the front-to-back direction is wider in the left-to-right direction, thereby providing sufficient space for the seat 2 to slide relative to the support member 3. Similarly, in the second position, positioning the first movable shaft 410 relative to the edge of the support member 3 in the left-to-right direction also provides as much space as possible for the seat 2 to move.

[0290] When the seat 2 is in the second position, the central axis c of the seat 2 does not deviate from the central axis c of the seat 2 in the fore-aft direction relative to the central axis c of the seat 2 in the first position. That is, in the second position, the central axis of the seat 2 is aligned with the central axis of the seat 2 in the left-right direction. In the second position, the seat 2 does not deviate from the base 1 in the fore-aft direction. This structural arrangement eliminates the need for the user to provide sufficient space for the safety seat to rotate the seat 2.

[0291] In the first position, the first movable shaft 410 and the second movable shaft 510 are arranged in the front-to-back direction, the first movable shaft 410 and the second movable shaft 510 are opposite to each other in the front-to-back direction, and the second movable shaft 510 is relatively located behind the first movable shaft 410;

[0292] The first movable axis 410 is aligned with the center of the support member 3 in the front-to-back direction, and the second movable axis 510 is aligned with the center of the support member 3 in the front-to-back direction. The alignment of the first movable axis 410 and the second movable axis 510 with the center of the support member 3 in the front-to-back direction enables symmetry in leftward and rightward rotation of the seat 2, thereby facilitating installation and use of the safety seat in a vehicle.

[0293] Of course, in other embodiments, the first movable axis 410 and the second movable axis 510 can also deviate from the center position of the support member 3 in the front and rear directions. Such a structural setting can also realize the rotation of the seat 2 in two directions, but different offset effects will be produced when rotating to the left and right, and the user experience is poor.

[0294] In this embodiment, the seat 2 can rotate from the first position to the second position or the third position without moving in the axial direction of the first movable shaft 410 or the second movable shaft 510, thereby ensuring the stability of the seat 2 rotation. Furthermore, the seat 2 and the support member 3 are connected by the first movable shaft 410 and the second movable shaft 510, resulting in a simple connection structure. The direct fit of the shaft groove facilitates installation while also reducing the number of components and saving costs.

[0295] The second guide structure 520 extends in the front-to-back direction and has a front end portion 521 and a rear end portion 522 that are positioned opposite to each other in the front-to-back direction. The first guide structure 42 has a left end portion 421 and a right end portion 422 that are positioned opposite to each other in the left-to-right direction and are located on opposite sides of the support member 3.

[0296] In the first position, the first movable axis 410 is located at the center of the first guide structure 42 in the left-right direction.

[0297] The first movable axis 410 is located at the center position of the first guide structure 42 in the left-right direction, and the left end 421 and the right end 422 of the first guide structure 42 are relative to each other in the left-right direction, so that when the first position is converted to the second position, the first movable axis 410 is symmetrical whether it moves toward the left end 421 or the right end 422.

[0298] When the first position is changed to the second position, the first movable shaft 410 moves toward the left end portion 421; a variety of safety seats can be provided according to the arrangement of the first guide structure 42;

[0299] The first type of safety seat, as shown in Figure 66, the position of the first movable axis 410 in the second position is opposite to the position in the first position in the left-right direction; when the first movable axis 410 slides along the first guide structure 42, the starting position of the first movable axis 410 is arranged along the left-right direction and is located on a straight line extending along the left-right direction.

[0300] The first guide structure 42 may be a linear groove and extend in the left-right direction. The extended shape of the first guide structure 42 may also be a curve or a broken line as a whole.

[0301] In the second safety seat, also known as the eleventh embodiment, as shown in FIG69 , when transitioning from the first position to the second position, the first movable axis 410 moves toward the left end portion 421. The first movable axis 410 in the second position is closer to the rear side of the base 1 than in the first position. In the second position, the distance between the first movable axis 410 and the rear side of the base 1 is less than the distance between the second movable axis 510 and the rear side of the base 1.

[0302] The above structure requires that in the first position, the distance between the first movable axis 410 and the rear side of the base 1 is L1. In the second position, the distance between the first movable axis 410 and the rear side of the base 1 is L2. L2 is greater than L1. That is, when moving toward the second position, the first movable axis 410 moves rearward a certain distance compared to the first position. Furthermore, the first movable axis 410 moves rearward beyond the position of the second movable axis 510 in the second position. This structural arrangement causes the line connecting the first movable axis 410 and the second movable axis 510 to be tilted rearward relative to the left-right direction in the second position. This allows the passenger space to be positioned relatively more rearward when the seat 2 is rotated to the left, making it more convenient for seat 2 to be used. Existing motorcycle doors often open sideways, and after opening, the door body does not open perpendicularly to the forward direction of the vehicle body, but rather toward the rear of the vehicle body. The above structure of the safety seat can better match the opening angle of the vehicle door, thereby providing a better user experience after the safety seat is installed.

[0303] For the above-mentioned second type of safety seat, that is, embodiment eleven, as shown in Figures 69-70, the first guide structure 42 is curved as a whole. From the center of the first guide structure 42 to the left end 421, the first guide structure 42 includes a first arc segment 4201 and a second arc segment 4202 arranged in sequence; the first arc segment 4201 is an arc as a whole, and the radius of the circle where the first arc segment 4201 is located is equal to the distance between the first movable axis 410 and the second movable axis 510, so that when in the first arc segment 4201, the first movable axis 410 rotates with the second movable axis 510 as the center.

[0304] Therefore, the curvature of the second arc segment 4202 is smaller than the curvature of the first arc segment 4201, and the curvature radius of the second arc segment 4202 is greater than the distance between the first movable axis 410 and the second movable axis 42, so that when moving along the second arc segment 4202, the first movable axis 410 slides in the first guide structure 42, and the second movable axis 510 slides in the second guide structure 520.

[0305] It is understandable that, in other embodiments, a third arc segment and a fourth arc segment may be further provided between the second arc segment 4202 and the left end portion 421 .

[0306] Of course, the first arc segment 4201 and the second arc segment 4202 may be replaced by straight lines, so that the entire extended shape of the first guide structure 42 is formed by multiple broken lines.

[0307] In this embodiment, the difference in curvature between the first arc segment 4201 and the second arc segment 4202 is small, so that the entire first guide structure 42 is arc-shaped as a whole, and the first guide structure 42 is arched in the direction away from the second guide structure 510. At the same time, the first guide structure 42 is arched toward the rear side of the base.

[0308] In this embodiment, during the initial rotation, the seat 2 will first rotate around the second movable axis 510. At this time, the second movable axis 510 is located near the rear end 522. At this time, the first movable axis 410 slides in the first arc segment 4201. After the first movable axis 410 slides to the second arc segment 4202, the second movable axis 510 slides along the second guide structure 520 toward the front end 521. When the second movable axis 510 slides, it pushes the seat 2 to slide to the left or right. The above-mentioned structural setting can make the seat 2 have a larger deflection amount when deflecting, and the use process will be smoother.

[0309] The seat further has a third position, the second position being symmetrically arranged with respect to the third position, and the seat 2 is rotated relative to the base 1 between the first position and the third position via the actuating structure; when the seat 2 is in the third position, the central axis of the seat 2 is offset in the left-right direction from the central axis of the seat 2 when it is in the first position;

[0310] When the first position changes to the second position, the first movable axis 410 moves toward the left end 421; when the first position changes to the third position, the first movable axis 410 moves toward the right end 422; the orientation of the seat 2 when it is in the second position is opposite to the orientation of the seat 2 when it is in the third position.

[0311] In other embodiments, the following design may be performed: when the first position changes to the second position, the first movable shaft 410 moves toward the right end portion 422; when the first position changes to the third position, the first movable shaft 410 moves toward the left end portion 421;

[0312] In the first position, the second movable shaft 510 is located at the rear end portion 522; in the second position, the second movable shaft 510 slides along the second guide structure 520 to the front end portion 521;

[0313] In the first position, the first movable shaft 410 is located at the center of the first guide structure 42 in the left-right direction, and the left end portion 421 and the right end portion 422 are symmetrically arranged relative to the center of the first guide structure 42. In the second position, the first movable shaft 410 slides along the first guide structure 42 to the left end portion 421 or the right end portion 422.

[0314] The seat also has a third position. When the first movable shaft 410 moves to the left end 421 in the second position, in the third position, the first movable shaft 410 moves to the right end 422.

[0315] When the first movable shaft 410 moves to the right end portion 422 at the second position, the first movable shaft 410 moves to the left end portion 421 at the third position.

[0316] When the seat 2 moves from the first position to the second position, the first movable shaft 410 slides in the first guide structure 42 toward the left end 421, and the seat 2 rotates from the forward position to the left position. The second movable shaft 510 moves along the second guide structure 520 from the rear end 522 toward the front end 521.

[0317] When the seat 2 moves from the first position to the third position, the first movable shaft 410 slides in the first guide structure 42 toward the right end 422, and the seat 2 rotates from the forward position to the right position. The second movable shaft 510 moves along the second guide structure 520 from the rear end 422 toward the front end 421.

[0318] In the second type of safety seat mentioned above, the seat 2 is installed facing forward when in use. For another type of seat 2 that is installed facing backward when in use, that is, Example 12, as shown in Figure 71, its first guide structure 42 is also curved as a whole, and the second guide structure 520 is straight as a whole. The front end of the second guide structure 520 is relatively arranged at a position close to the front side of the base 1. The second guide structure 520 is arc-shaped as a whole and arches in the direction away from the first guide structure 42. In this method, its movement process is similar to that of the safety seat of the second method. The only difference between the two is the offset during rotation caused by the different installation and use methods of the seats, which will not be elaborated here.

[0319] When the seat 2 is placed in the first position, the axis lines of the first movable axis 410 and the second movable axis 510 are perpendicular to and intersect with the longitudinal axis M3 of the base 1 , that is, the first movable axis 410 and the second movable axis 510 are collinearly arranged.

[0320] In a specific embodiment, as shown in Figures 64, 65, and 66, the first guide structure 42 and the second guide structure 520 are both linear grooves. The first guide structure 42 extends along the first direction, and the second guide structure 520 extends along the second direction. The second guide structure 520 is disposed on one side of the first guide structure 42. The first movable shaft 410 slides in the first guide structure 42, and the second movable shaft 510 slides in the second guide structure 520.

[0321] While the seat is rotated from the first position to the second position or the third position, the seat 2 can extend outward relative to the base 1 at the second position or the third position, making it convenient for the user to place the child on the seat 2 or remove the child from the seat 2 without the user having to bend over or stretch the body into the car.

[0322] Further optionally, the second guide structure 520 is perpendicular to the first guide structure 42 and is disposed at the rear end of the seat 2 or the support member 3, with the first guide structure 42 being symmetrically disposed relative to the second guide structure 520. When the seat 2 is in the first position, the second movable shaft 510 is disposed at the end of the second guide structure 520 facing away from the first guide structure 42. The groove wall of the second guide structure 520 limits the position of the second movable shaft 510. The first movable shaft 410 is disposed in the middle of the first guide structure 42. The groove wall of the first guide structure 42 limits the position of the first movable shaft 410 in the first direction, ensuring that the seat 2 in the first position does not move in the second direction. During the rotation of the seat 2 from the first position to the second position, the first movable shaft 410 slides within the first guide structure 42 positioned on one side of the second guide structure 42. During the rotation of the seat 2 from the first position to the second position, the second movable shaft 510 slides within the first guide structure 42 positioned on the other side of the second guide structure 520. Therefore, the first guide structure 42 is symmetrically arranged relative to the second guide structure 520, ensuring that the first and second movable trajectories are identical, i.e., the two rotational positions of the seat 2 are symmetrical. When the seat 2 rotates to the second or third position, the end sidewalls of the first guide structure 42 limit the first movable shaft 410, i.e., limit the position at which the seat 2 extends outward relative to the base 1.

[0323] In some other feasible solutions, the second guide structure 520 is perpendicular to the first guide structure 42 , and the second guide structure 520 is arranged at the front end of the seat 2 or the support member 3 , and the first guide structure 42 is symmetrically arranged relative to the second guide structure 520 .

[0324] In a specific embodiment, when the seat 2 rotates from the first position to the second position, it forms a first movement trajectory, and the seat 2 can rotate continuously relative to the base 1 along the first movement trajectory. When the seat 2 rotates from the first position to the third position, it forms a second movement trajectory. Both the first movement trajectory and the second movement trajectory are curved, and the seat 2 can rotate continuously relative to the base 1 along the second movement trajectory. Further, optionally, the second movement trajectory does not intersect with the first movement trajectory, and the seat 2 always remains in the same plane when moving along the first movement trajectory and the second movement trajectory. This prevents the seat 2 from fluctuating perpendicular to the horizontal plane during rotation, thereby ensuring the stability of the seat 2's rotation. Furthermore, the second movement trajectory does not intersect with the first movement trajectory. During rotation to the second position, the seat 2 does not move within the second movement trajectory and can only rotate to the second position. During rotation to the third position, the seat 2 does not move within the first movement trajectory and can only rotate to the third position. This improves the controllability of the seat 2's rotation position and prevents the seat 2 from wobbling between the first and second movement trajectories during rotation.

[0325] When the seat 2 moves along the first moving trajectory or the second moving trajectory, the first moving shaft 410 and the second moving shaft 510 are respectively axially fixed and rotate circumferentially relative to the seat 2 or the base 1. The seat 2 can rotate from the first position to the second position or the third position. The seat 2 will not move in the axial direction of the first moving shaft 410 or the second moving shaft 510, ensuring the stability of the rotation of the seat 2. The seat 2 and the support 3 are connected by the first moving shaft 410 and the second moving shaft 510, and the connection structure is simple.

[0326] In this embodiment, the support member 3 can enable the seat 2 to rotate 360° around the circumference to any position relative to the base 1, so as to facilitate adjustment of the child's position in the car and make it easier for the user to take care of the child in the car.

[0327] The setting of the support member 3 enables the seat 2 to rotate 360° around the circumference to any position relative to the base 1. In some embodiments, as shown in Figures 70 and 71, a first base plate 70 is fixedly provided on the support member 3, and a second base plate 80 is provided on the base 1. The first base plate 70 is rotatably connected to the second base plate 80, and the first base plate 70 can rotate 360° around the circumference to any position relative to the second base plate 80.

[0328] Optionally, a rotating shaft is provided on the first base plate 70, one end of the rotating shaft being connected to the first base plate 70, the other end of the rotating shaft passing through the second base plate 80, and the other end of the rotating shaft being sleeved with a retaining ring 60. The retaining ring 60 contacts the second base plate 80, allowing the rotating shaft to rotate relative to the second base plate 80. Optionally, the retaining ring 60 is rotationally connected to the second base plate 80, while the rotating shaft is fixedly connected to the retaining ring 60. The provision of the retaining ring 60 can reduce wear on the rotating shaft. Alternatively, the retaining ring 60 is fixedly connected to the second base plate 80, while the rotating shaft is rotationally connected to the retaining ring 60. The provision of the retaining ring 60 can reduce wear on the second base plate 80.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
