Description

Technical Field

[0001] This utility model relates to the field of child car safety seats, specifically to a safety seat. Background Technology

[0002] Child car seats provide protection for children's safety while traveling in vehicles. Most car seats on the market are fixed to the car seat, requiring parents to bend over and reach into the car to place their child, which is inconvenient. Some child car seats now offer orientation adjustment to accommodate children of different ages for both forward-facing and rear-facing use. These seats can be rotated to face the door before placing the child, but this still requires the operator to bend over and reach into the car, which is also inconvenient. Utility Model Content

When this safety seat is installed in a car seat, during the process of switching the seat body from the first position to the second position, the seat body can gradually extend outward relative to the base, or the outward extension relative to the base can become increasingly larger, or even partially extend outside the car door. Thus, when placing a child on the seat body or removing a child from the seat body, the user does not need to bend over or reach into the car to operate, making it more convenient to use. The smooth movement trajectory can increase the comfort and stability of the ride. Attached Figure Description

[0100] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0101] The following descriptions of directions such as front, back, left, right, up, and down are all defined with reference to the direction observed by the child in the car seat when the car seat is installed facing forward in the car seat. The purpose is only to clearly illustrate the relative positional relationship of the various components in the car seat.

[0102] Referring to the accompanying drawings, the present invention provides a safety seat comprising a base 1 and a seat body 2. The seat body 2 has a first position and a second position relative to the base 1. The safety seat also includes an actuating structure disposed between the base 1 and the seat body 2, through which the seat body 2 can move relative to the base 1. When the seat body 2 is in the first position, the orientation of the seat body 2 is a first direction. When the seat body 2 moves to the second position via the actuating structure, the axis of the seat body 2 deviates from the axis of the seat body 2 when it is in the first position, and the orientation of the seat body 2 is a second direction different from the first direction.

[0103] Specifically, the seat body 2 includes a supporting body and a supporting member 20, the supporting member 20 being located at the bottom of the supporting body and engaging with the supporting body; a support member 3 is provided on the base 1, such as... Figure 7As shown, the seat body 2 is connected to the base 1 via a carrier 20, specifically to a support 3 on the base 1. The carrier 20 is located between the support 3 and the carrier body. The carrier body can be integrally formed with the carrier 20 or separately formed; the two can be assembled or disassembled. Thus, different carrier bodies can be selected to engage with the carrier 20 and be installed on the base 1 according to usage requirements. Specifically, the carrier body can be... Figure 1 , Figure 2 and Figure 5 The baby carrier 21 shown is suitable for use by younger infants and toddlers, and can also be used for... Figure 3 , Figure 4 and Figure 6 The safety seat 22 shown is designed for use by older children.

[0104] The first direction can be forward or backward, and correspondingly, the second direction is left or right. That is, when the seat body 2 is in the first position, it faces forward or backward, and when the seat body 2 is switched to the second position, it faces left or right.

[0105] Specifically, see Figures 1 to 2 As shown, the main support structure of the seat body 2 is the basket 21. Figure 1 In the state shown, basket 21 is in the first position and facing backward; Figure 2 In the indicated state, basket 21 is in the second position, facing to the right. Figure 2 The axis of the basket 21 is off-center under the current state. Figure 1 In the current state, the axis of the carrier 21 is such that the carrier 21 protrudes further outward in the left and right directions relative to the base 1. Thus, when the car seat is installed in the car seat, when the carrier 21 is switched to the second position, the carrier 21 can be closer to the car door frame, and even part of it can extend outside the door frame. This makes it easier for parents to place the child in the carrier 21 and secure it to the carrier 21.

[0106] Similarly, see Figures 3 to 4 As shown, the main support of the seat body 2 is the safety seat 22, which is suitable for older children. Figure 3 In the indicated state, safety seat 22 is in the first position and facing forward; Figure 4 In the indicated state, safety seat 22 is in the second position, facing to the right. Figure 4 The axis of safety seat 22 deviated in the current state Figure 3 In this state, the axis of the safety seat 22 is such that the safety seat 22 protrudes further outward in the left and right directions relative to the base 1, making it easier for parents to place the child on the safety seat 22 and restrain them on the safety seat 22.

[0107] In some embodiments, the seat body 2 also has a third position symmetrically arranged with respect to the second position. The seat body 2 can also be moved to the third position via an actuating mechanism. The orientation of the seat body 2 in the third position is opposite to that in the second position. That is, when the seat body 2 is in the second and third positions, the orientation of the seat body 2 is to the right and to the left, respectively. This allows the user to easily select whether to switch the seat body 2 to the second or third position based on the installation position of the child safety seat in the car seat, thereby facing the corresponding side of the car door.

[0108] In some embodiments, for this safety seat, when the seat body 2 moves from a first position to a second position via the aforementioned actuation mechanism, it forms a smooth first movement trajectory, and the seat body 2 can continuously rotate relative to the base 1 along this first movement trajectory; when the seat body 2 moves from the first position to a third position via the aforementioned actuation mechanism, it forms a smooth second movement trajectory, and the seat body 2 can also continuously rotate relative to the base 1 along this second movement trajectory. The aforementioned first movement trajectory and second movement trajectory are intersecting, and the seat body 2 remains in the same plane when moving along the first movement trajectory and the second movement trajectory. Optionally, the aforementioned first movement trajectory and second movement trajectory are located in the same horizontal plane.

[0109] Figures 7 to 15 In the illustrated embodiment, the actuating structure includes a first shaft 4 and a second shaft 5, which are mounted on the seat body 2, specifically on the support member 20 of the seat body 2. When the seat body 2 moves along the first moving trajectory W1, the first shaft 4 is axially fixed and rotates circumferentially relative to the base 1 or the seat body 2, and the seat body 2 moves along the first moving trajectory W1, such as... Figure 14 As shown; when the seat body 2 moves along the second moving trajectory W2, the second shaft 5 is axially fixed and rotates circumferentially relative to the base 1 or the seat body 2, and the seat body 2 moves along the second moving trajectory W2, as shown. Figure 15 As shown. Specifically, the base 1 has a first central axis M1 extending longitudinally. When the seat body 2 is in the first position, the center lines of the first axis 4 and the second axis 5 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.

[0110] Figures 7 to 15In the illustrated embodiment, the actuating structure further includes two first grooves 31 and 32 respectively disposed opposite to the first shaft 4 and the second shaft 5. The first grooves 31 and 32 are disposed on the base 1 and extend in an arc-shaped intersection, so that the first shaft 4 or the second shaft 5 can drive the seat body 2 to move in the first grooves 31 or 32, and the center of the first grooves 31 and 32 is offset from the aforementioned first central axis M1 of the base 1. Here, the first grooves 31 and 32 are disposed on the support member 3. The first moving trajectory W1 coincides with or partially coincides with the first groove 31, and the starting point and ending point of the first moving trajectory W1 are the two ends of the first groove 31, respectively. The second moving trajectory W2 coincides with or partially coincides with the first groove 32, and the starting point and ending point of the second moving trajectory W2 are the two ends of the first groove 32, respectively. The support member 3 is disc-shaped and can rotate on the base 1 around the center line extending in the vertical direction, so that the support member 3 can rotate 180° or 360° as a whole, so that the seat body 2 can switch between the forward facing direction and the backward facing direction. The center of the first grooves 31 and 32 is also offset from the center of the support member 3.

[0111] like Figure 14 As shown, when the seat body 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 body 2 to move in the first groove 31, so that the entire seat body 2 rotates continuously around the axis of the first shaft 4, thereby reaching the second position; as shown Figure 15 As shown, when the seat body 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 body 2 to move in the second groove 201, so that the seat body 2 rotates continuously around the second shaft 5 to reach the third position.

[0112] See Figure 13 , Figure 14 , Figure 15 As shown, when the seat body 2 is in the first position, it has a first axis extending in the vertical direction, the projection of which in the top view is P1. The first axis intersects perpendicularly with the first central axis M1 of the base 1. The seat body 2 has a second central axis M2 extending longitudinally, which coincides with the first central axis M1 of the base 1. The projection P1 falls on the second central axis M2 of the seat body 2.

[0113] When the seat body 2 is in the second or third position, the second central axis M2 of the seat body 2 rotates by a certain angle, specifically, it rotates to be perpendicular to the first central axis M1 of the base 1. The seat body 2 has a second axis extending in the vertical direction, the projection of which in the top view is P2. Along the second direction, the distance between the first axis and the second axis, that is, the distance between P1 and P2, is L > 0, for example, 50mm. <L<250mm。

[0114] In other embodiments, the first shaft 4 and the second shaft 5 may be disposed on the base 1, and the two first grooves 31 and 32 may be disposed on the seat body 2.

[0115] See Figures 16 to 23 Another embodiment of the safety seat is provided. In this embodiment, the actuating structure further includes two second grooves 201 respectively disposed opposite to the first shaft 4 and the second shaft 5. The first shaft 4 and the second shaft 5 are axially telescopically disposed on one of the seat body 2 and the base 1, and the second grooves 201 are disposed on the other of the base 1 and the seat body 2, so that the first shaft 4 and the second shaft 5 can be inserted into or disengaged from the second 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 body 2 or the base 1, or to shorten their length along their own axis to achieve axial extension and contraction relative to the seat body 2 or the base 1. Here, the first shaft 4 and the second shaft 5 are disposed on the support member 20 of the base 1; the two second grooves 201 are disposed on the seat body 2, specifically on the support member 20 of the seat body 2. During the process of the seat body 2 changing from the first position to the second position, such as Figure 17 As shown, the second shaft 5 disengages from the second groove 201, causing the seat body 2 to rotate relative to the base 1 around the first shaft 4, thereby reaching the second position along the first moving trajectory; during the process of the seat body 2 changing from the first position to the third position, as... Figure 18 As shown, the first axis 4 disengages from the second groove 201, causing the seat body 2 to rotate relative to the base 1 around the second axis 5, thereby reaching the third position along the second movement trajectory.

[0116] In some embodiments, a first guide trajectory is formed when the seat body 2 moves from the first position to the second position, and a second guide trajectory is formed when the seat body 2 moves from the first position to the third position. Since the third position is symmetrically arranged with respect to the second position, the first guide trajectory and the second guide trajectory are symmetrically arranged to ensure that the seat body 2 can move smoothly and stably to the second position or the third position. Optionally, the first guide trajectory and the second guide trajectory are symmetrically arranged with respect to the first central axis M1 of the base 1, so that the external position states of the seat body 2 in the second and third positions are symmetrical with respect to the first central axis M1 of the base 1.

[0117] Based on the aforementioned first moving trajectory W1 and second moving trajectory W2, in order to enable the seat body 2 to move smoothly between the first position and the second position or between the first position and the third position, both the first guide trajectory and the second guide trajectory are smooth arcs, and the first guide trajectory and the second guide trajectory are intersected. 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 grooves 31 to form the first moving trajectory, the trajectory of the second shaft 5 sliding in the other first groove 32 is the first guide trajectory; when the second shaft 5 slides in the other first groove 32 to form the second moving trajectory, the trajectory of the first shaft 4 sliding in one of the first grooves 31 is the second guide trajectory. The cooperation between the first shaft 4 and the first groove 32 and the cooperation between the second shaft 5 and the first groove 32 each have two functions, simplifying the connection structure between the seat body 2 and the base 1.

[0118] The safety seat also includes a locking structure 6 and an unlocking structure 7. The locking structure 6 is located on one of the seat body 2 and the base 1 and is used to selectively lock the first axis 4 and / or the second axis 5. The unlocking structure 7 is connected to the locking structure 6 and is used to release the locking structure 6.

[0119] See Figures 7 to 15 In the embodiment shown, 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 disposed on the base 1; the unlocking structure 7 includes an unlocking member that is connected to the locking member by a traction member, and when the unlocking member is unlocked, the locking member is rotated relative to the base 1 by the traction member to unlock.

[0120] The safety seat also includes a limiting structure disposed between the locking member and the traction member. This limiting structure includes a connecting portion and a protrusion. The connecting portion connects the locking member and the traction member, and a fifth groove is provided on the connecting portion. The protrusion is slidably disposed in the fifth groove. When the unlocking member is unlocked, it slides relative to the protrusion via the traction member, thereby limiting the movement distance of the locking member and defining its rotation trajectory when the locking member rotates relative to the base 1. A resilient member for resetting may be provided between the base 1 and the unlocking structure 7.

[0121] Specifically, in this 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 mounted on the base 1 about the first rotating shaft 63, and the second locking member 62 is rotatably mounted on the base 1 about the second rotating shaft 65. The unlocking structure 7 includes two unlocking members, namely a first unlocking button 73 and a second unlocking button 74. One end of the first spring 67 and the second spring 68 are connected to the base 1, and the other end is connected to the first unlocking button 73 and the second unlocking button 74 respectively through the linkage structure of the unlocking structure 7. The first unlocking button 73 is connected to the second locking member 62 through the first traction member 71, which can drive the second locking member 62 to rotate relative to the base 1 to unlock. The second unlocking button 74 is connected to the first locking member 61 through the second traction member 72, which can drive the first locking member 61 to rotate relative to the base 1 to unlock.

[0122] More specifically, see Figure 12 As shown, the first locking member 61 includes a first locking part 611 and a first connecting part 612. The first locking part 611 can be the free end of the first locking member 61. The first locking part 611 is used to hook the first shaft 4 and fix it relative to the base 1. The first connecting part 612 is used to connect with the second traction member 72. The first locking part 611 and the first connecting part 612 are located on opposite sides of the first rotating shaft 63. The first connecting part 612 is also provided with a fifth groove, specifically a first guide groove 613. The first guide groove 613 is an arc-shaped groove with the axis of rotation of the first rotating shaft 63 as the center of rotation. The base 1 is also provided with a first protrusion, specifically a first guide post 64. The first guide post 64 can be slidably inserted into 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.

[0123] Similarly, the second locking member 62 includes a first locking part 621 and a second connecting part 622. The first locking part 621 can be the free end of the first locking part 621. The second locking part 621 is used to hook the second shaft 5 and fix it relative to the base 1. The second connecting part 622 is used to connect with the first traction member 71. The second locking part 621 and the second connecting part 622 are located on opposite sides of the second rotating shaft 65. The second connecting part 622 is also provided with a second guide groove 623. The second guide groove 623 is an arc-shaped groove with the axis of rotation of the second rotating shaft 65 as the center of rotation. The base 1 is also provided with a second guide post 66. The second guide post 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.

[0124] When the first unlock button 73 is operated, the second traction member 72 pulls the second connecting part 622, causing the second locking member 62 to rotate around the second pivot 65 in a third direction (clockwise in this embodiment). The second spring 68 is stretched, and the second locking part 621 moves away from the second axis 5 to release the hook on the second axis 5. Then, the seat body 2 is driven to rotate, and the second axis 5 can move in the first groove 32, causing the seat body 2 to rotate around the first axis 4 and move relative to the base 1 along the first moving trajectory, thereby causing the seat body 2 to switch from the first position to the second position. During this process, the second locking member 62 switches from the state of locking the second axis 5 to the state of releasing the second axis 5. When the seat body 2 is switched from the second position to the first position, the second traction member 72 pulls the second connecting part 622, causing the second locking member 62 to rotate around the second pivot 65 in the opposite direction. The second spring 68 is reset, and the first locking part 621 hooks the second shaft 5. During this process, the second locking member 62 switches from the state of releasing the second shaft 5 to the state of locking the second shaft 5. The first locking member 61 always locks the first shaft 4 or releases the first shaft 4.

[0125] When the second unlock button 74 is operated, the first traction member 71 pulls the first connecting part 612, causing the first locking member 61 to rotate around the first rotating shaft 63. The first spring 67 is stretched, and the first locking part 611 moves away from the first shaft 4, releasing the hook lock on the first shaft 4. Subsequently, it drives the seat body 2 to rotate, allowing the first shaft 4 to move in the first groove 31. This causes the seat body 2 to rotate around the second shaft 5 and move relative to the base 1 along the second movement trajectory, thereby switching the seat body 2 from the first position to the third position. During this process, the first locking member 61 switches from a state of locking the first shaft 4 to a state of releasing the first shaft 4. When the seat body 2 switches from the second position to the first position, the first traction member 71 pulls the first connecting part 612, causing the first locking member 61 to rotate around the first rotating shaft 63 in the opposite direction. The first spring 67 returns to its original position, and the first locking part 621 hooks onto the second shaft 5. During this process, the first locking member 61 switches from a state of releasing the first shaft 4 to a state of locking the first shaft 4. The second locking member 62 always locks or releases the second shaft 5.

[0126] exist Figures 16 to 23 In the embodiment shown, the locking structure 6 is configured in the same way as... Figures 7 to 15 The embodiments shown are different. 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, so that the first shaft 4 and the second shaft 5 extend axially toward the bearing member 20, and the first shaft 4 and the second shaft 5 are inserted into the corresponding second groove 201.

[0127] A mating structure is provided between the first locking member 61 and the first shaft 4, so that after the first locking member 61 is driven to rotate, it can drive the first shaft 4 away from the bearing member 20 and retract. This mating structure can be a wedge-shaped surface structure provided between the two, such as... Figure 22 As shown, the first shaft 4 has 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 part 61b, which can be the free end of the first locking member 61 or part of the closed loop of the first locking member 61 and corresponds to the starting end of the second inclined surface 61a (e.g., Figure 22 (As shown). 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, making the horizontal height of the first inclined surface 41 relative to the second inclined surface 61a higher, and the first shaft 4 is inserted into the corresponding second groove 201. When the first locking member 61 rotates around 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 part 61b moves towards the first shaft 4, thereby disengaging the first shaft 4 from the corresponding second groove 201 and unlocking it. Similarly, the second locking member 62 and the second shaft 5 are also provided with a mating structure, so that after the second locking member 62 is driven to rotate, it can drive the second shaft 5 away from the support member 20 to slide or shorten, thereby disengaging the second shaft 5 from the corresponding second groove 201 and unlocking it.

[0128] Thus, when the first unlock button 73 is operated to unlock, the second traction member 72 pulls the second locking member 62 to rotate around the second axis 5. The second locking member 62 rotates in a fourth direction opposite to the third direction (counterclockwise in this embodiment). The second inclined surface 61a pushes the first inclined surface 41 to move downward. Then, the second axis 5 slides or extends downward along the axial direction. The free end of the second locking member 62 moves towards the second axis 5, thereby disengaging the second axis 5 from the second groove 201 on the support member 20 and unlocking it. Subsequently, it drives the seat body 2 to rotate. The seat body 2 rotates around the first axis 4 and moves relative to the base 1 along the first moving trajectory, thereby switching the seat body 2 from the first position to the second position.

[0129] When the second unlock button 74 is operated to unlock, the first traction member 71 pulls the first locking member 61 to rotate around the first axis 4, the second inclined surface 61a pushes the first inclined surface 41 to move downward, and then the first axis 4 slides or extends downward along the axis, causing the free end of the first locking member 61 to move towards the first axis 4, so that the first axis 4 disengages from the second groove 201 on the support member 20 to achieve unlocking. Subsequently, the seat body 2 is driven to rotate, and the seat body 2 rotates around the second axis 5 and moves relative to the base 1 along the second movement trajectory, so that the seat body 2 switches from the first position to the third position.

[0130] In other embodiments, Figure 24 and Figure 25 FIG. Figure 25 is a schematic view of the seat body 2 in the first position. Figure 26 and Figure 27 FIG. Figure 27 is a schematic view of the seat body 2 in the second or third position. As shown in Figures 24 to 27 FIG. Figures 24 to 27 , the first movement trajectory and the second movement trajectory are not cross - set, and the seat body 2 is always located in the same plane when moving along the first movement trajectory and along the second movement trajectory. As an optional way, the above - mentioned first movement trajectory and the second movement trajectory are located in the same horizontal plane.

[0131] The base 1 has a base axis a, the seat body 2 has a second central axis M2 extending along the longitudinal direction of the seat body 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 body 2 is in the first position, the axis b coincides with the base axis a. When the seat body 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 L>0, for example, 50mm < L < 250mm. When the seat body 2 is in the second or third position, the seat body 2 does not generate displacement in the front - rear direction and extends a distance of L in the left or right direction. When the user places the child on the seat body 2 or takes the child off the seat body 2, there is no need to bend down or stretch the body into the car for operation, which is more convenient to use.

[0132] The actuating structure includes a first shaft 4 and a second shaft 5 provided on one of the seat body 2 and the base 1, and the other of the seat body 2 and the base 1 is provided with a third groove 43 and a fourth groove 44 corresponding to the first shaft 4 and the second shaft 5. Both the third groove 43 and the fourth groove 44 are linear grooves. When the seat body 2 moves along the first movement trajectory, the seat body 2 is axially fixed and rotates relative to the base 1, the first shaft 4 slides into the third groove 43, and the second shaft 5 slides out of the fourth groove 44, forming the first movement trajectory, without affecting the rotation of the seat body 2 relative to the base 1, so that the seat body 2 can move from the first position to the second position. When the seat body 2 moves along the second movement trajectory, the seat body 2 is axially fixed and rotates relative to the base 1, the second shaft 5 slides into the fourth groove 44, and the first shaft 4 slides out of the third groove 43, forming the second movement trajectory, without affecting the rotation of the seat body 2 relative to the base 1, so that the seat body 2 can move from the first position to the third position. Optionally, the third groove 43 and the fourth groove 44 are provided on the seat body 2, and the first shaft 4 and the second shaft 5 are provided on the base 1. The seat body 2 is rotatably connected to the base 1, and the first shaft 4 and the second shaft 5 can rotate along their own axes respectively, ensuring that the seat body 2 can rotate smoothly.

[0133] As shown in Figure 28 and Figure 29As shown, one end of the third groove 43 passes through the edge of the seat body 2 or the base 1, allowing the first shaft 4 to slide out of the third groove 43. One end of the fourth groove 44 passes through the edge of the seat body 2 or the base 1, allowing the second shaft 5 to slide out of the fourth groove 44. The fit is simple. When the seat body 2 is in the first position, the third groove 43 and the fourth groove 44 are symmetrically arranged with respect to the first central axis M1 of the base 1. The third groove 43 and the fourth groove 44 are located at the rear end of the seat body 2 or the base 1, and the third groove 43 and the fourth groove 44 are inclined from the edge of the seat body 2 or the base 1 toward the first central axis M1 of the base 1. In some other embodiments, the third groove 43 and the fourth groove 44 may also be located at the front end of the seat body 2 or the base 1, symmetrically arranged with the third groove 43 and the fourth groove 44 located at the rear end.

[0134] Figure 30 and Figure 31 This is a diagram showing the intermediate position of the seat body 2 as it rotates from the first position to the second or third position. (See diagram below.) Figures 29 to 31 As shown, one of the seat body 2 and the base 1 is provided with a sliding shaft 54, and the other of the seat body 2 and the base 1 is provided with a sliding groove 55. The sliding shaft 54 ​​is slidably disposed within the sliding groove 55. When the seat body 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 body 2. When the seat body 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 body 2, preventing the seat body 2 from rotating excessively. Optionally, the sliding groove 55 is a semi-circular groove. When the seat body 2 is placed in the first position, the sliding groove 55 is symmetrically arranged with respect to the first central axis M1 of the base 1, and the sliding shaft 54 ​​is placed in the middle of the sliding groove 55. When the seat body 2 is placed in the second position, the sliding shaft 54 ​​is placed at one end of the sliding groove 55. When the seat body 2 is placed in the third position, the sliding shaft 54 ​​is placed at the other end of the sliding groove 55. When the seat body 2 is placed in the second or third position, the sliding groove 55 limits the seat body 2 to only rotate 90°, which can meet the user's needs and facilitate the user to remove and place the child from the safety seat.

[0135] When the seat body 2 moves from the first position to the second position, a first guide trajectory is formed; when the seat body 2 moves from the first position to the third position, a second guide trajectory is formed. The first and second guide trajectories are symmetrically arranged. Because the third position is symmetrically arranged with respect to the second position, the symmetrical arrangement of the first and second guide trajectories ensures that the seat body 2 can move smoothly and stably to the second or third position. Optionally, the first and second guide trajectories are symmetrically arranged relative to the first central axis M1 of the base 1, so that the external position states of the seat body 2 in the second and third positions are symmetrical with respect to the first central axis M1 of the base 1.

[0136] Both the first and second guide trajectories are straight lines, and the first guide trajectory connects with the second guide trajectory. The first and second guide trajectories are independent motion trajectories; that is, the first guide trajectory does not intersect with the first moving trajectory, and the second guide trajectory does not intersect with the second moving trajectory. Optionally, one of the seat body 2 and the base 1 is provided with a guide slider 53 and is rotatably connected to the guide slider 53, while the other is provided with a guide groove 52. When the seat body 2 moves along the first moving trajectory, the guide slider 53 slides within the guide groove 52 to form the first guide trajectory, and the seat body 2 rotates circumferentially relative to the base 1. When the seat body 2 moves along the second moving trajectory, the guide slider 53 slides within the guide groove 52 to form the second guide trajectory, and the seat body 2 rotates circumferentially relative to the base 1. The guide groove 52 extends in the left and right direction and is symmetrically arranged with respect to the first central axis M1 of the base 1. When the seat body 2 is placed in the first position, the guide slider 53 is placed in the middle position of the guide groove 52. When the seat body 2 moves from the first position to the second position, the guide slider 53 slides towards one end of the guide groove 52. When the seat body 2 moves from the first position to the third position, the guide slider 53 slides towards the other end of the guide groove 52.

[0137] Optionally, the seat body 2 is provided with a guide slider 53, and the base 1 is provided with a guide groove 52. The seat body 2 and the guide slider 53 are rotatably connected. The base 1 is provided with a support member 3, and the guide groove 52 is disposed on the support member 3. The guide slider 53 has an I-shaped structure, with both ends of the guide slider 53 slidably connected to the guide groove 52, and the middle part of the guide slider 53 rotatably connected to the seat body 2.

[0138] The support member 3 is disc-shaped and can rotate on the base 1 around the base axis a extending in the vertical direction, so that the support member 3 can rotate 180° or 360° as a whole, so that the seat body 2 can switch between the forward facing direction and the backward facing direction. The center of the third groove 43 and the fourth groove 44 is also offset from the center of the support member 3.

[0139] Figure 32 This is a diagram showing the seat body 2 in the first position. Figure 33 This is a diagram showing the process of the seat body 2 moving from the first position to the second position. Figure 34 This is a diagram showing the seat body 2 in the second position. Figure 35 This is a diagram showing the process of the seat body 2 moving from the first position to the third position. Figure 36 This is a diagram showing the seat body 2 in the third position. Other embodiments, such as... Figures 32 to 36As shown, the first movement trajectory and the second movement trajectory are arranged without intersection, and the seat body 2 always lies in the same plane when moving along the first movement trajectory and along the second movement trajectory. As an optional way, the first movement trajectory and the second movement trajectory are in the same horizontal plane.

[0140] Combined with Figure 36 and Figure 37 As shown, the base 1 has a base axis a, the seat body 2 has a second central axis M2 extending along the longitudinal direction of the seat body 2 and an axis b perpendicular to and intersecting the second central axis M2, and the axis b is parallel to the base axis a. When the seat body 2 is in the first position, the axis b coincides with the base axis a. When the seat body 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, 50mm < L < 250mm. When the seat body 2 is placed in the second position or the third position, the seat body 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 body 2 or takes the child off the seat body 2, there is no need to bend down or stretch the body into the vehicle for operation, which is more convenient to use.

[0141] The actuating structure includes a first shaft 4 and a second shaft 5 provided on one of the seat body 2 and the base 1. When the seat body 2 moves along the first movement trajectory, the axial direction of the first shaft 4 is fixed and it rotates circumferentially relative to the seat body 2 or the base 1, and the seat body 2 moves along the first movement trajectory. When the seat body 2 moves along the second movement trajectory, the axial direction of the second shaft 5 is fixed and it rotates circumferentially relative to the seat body 2 or the base 1, and the seat body 2 moves along the second movement trajectory. The first shaft 4 and the second shaft 5 are provided on the seat body 2, and are specifically provided on the carrier 20 of the seat body 2. The base 1 has a first central axis M1 extending longitudinally. When the seat body 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.

[0142] The actuation structure also includes two first grooves 31 and 32 respectively disposed opposite to the first shaft 4 and the second shaft 5. The first grooves 31 and 32 are disposed on the other of the seat body 2 and the base 1 and extend in an arc shape. The two first grooves 31 and 32 are not intersecting, so that the first shaft 4 or the second shaft 5 can drive the seat body 2 to move in the first grooves 31 and 32. The center of the first grooves 31 and 32 is offset from the first central axis M1 of the base 1. Here, the base 1 is provided with a support member 3, and the first grooves 31 and 32 are disposed on the support member 3. The first moving trajectory coincides with or partially coincides with the first groove 31, and the starting point and ending point of the first moving trajectory are the two ends of the first groove 31, respectively. The second moving trajectory coincides with or partially coincides with the first groove 32, and the starting point and ending point of the second moving trajectory are the two ends of the first groove 32, respectively. The support member 3 is disc-shaped and can rotate on the base 1 around the base axis a extending in the vertical direction, so that the support member 3 can rotate 180° or 360° as a whole, so that the seat body 2 can switch between the forward facing direction and the backward facing direction. The center of the first groove 31 and 32 is also offset from the center of the support member 3.

[0143] In other embodiments, the first shaft 4 and the second shaft 5 may be disposed on the base 1, and the two first grooves 31 and 32 may be disposed on the seat body 2.

[0144] The seat body 2 and the base 1 are each provided with a first clearance groove 45 and a second clearance groove 46. When the seat body 2 moves along a first moving trajectory, the second clearance groove 46 is used to avoid it; when the seat body 2 moves along a second moving trajectory, the first clearance groove 45 is used to avoid it. Specifically, the first clearance groove 45 is used to avoid the second shaft 5, and the second clearance groove 46 is used to avoid the first shaft 4. Furthermore, the shape of the first clearance groove 45 is set according to the second moving trajectory, and the shape of the second clearance groove 46 is set according to the first moving trajectory.

[0145] One end of the first clearance groove 45 connects to the first moving trajectory, that is, the first clearance groove 45 communicates with the first groove 31 forming the first moving trajectory. One end of the second clearance groove 46 connects to the second moving trajectory, that is, the second clearance groove 46 communicates with the first groove 32 forming the second moving trajectory. The first clearance groove 45 and the second clearance groove 46 are intersecting. The other end of the second clearance groove 46 is used to limit the rotation angle of the seat body 2 when it moves from the first position to the second position, and the other end of the first clearance groove 45 is used to limit the rotation angle of the seat body 2 when it moves from the first position to the third position. The seat body 2 rotates 90° when it moves from the first position to the second position or the third position.

[0146] like Figures 36 to 39As shown, when the seat body 2 moves from the first position to the second position, a first guide trajectory is formed; when the seat body 2 moves from the first position to the third position, a second guide trajectory is formed. The first and second guide trajectories are symmetrically arranged. Because the third position is symmetrically arranged with respect to the second position, the symmetrical arrangement of the first and second guide trajectories ensures that the seat body 2 can move smoothly and stably to the second or third position. Optionally, the first and second guide trajectories are symmetrically arranged with respect to the first central axis of the base 1, so that the positional states of the seat body 2 in the second and third positions are symmetrical with respect to the first central axis of the base 1.

[0147] Both the first and second guide trajectories are straight lines, and the first guide trajectory connects with the second guide trajectory. The first and second guide trajectories are independent motion trajectories; that is, the first guide trajectory does not intersect with the first moving trajectory, and the second guide trajectory does not intersect with the second moving trajectory. Optionally, a guide shaft 51 is provided on either the seat body 2 or the base 1. When the seat body 2 moves along the first moving trajectory, the axial direction of the guide shaft 51 is fixed, and it rotates circumferentially relative to the seat body 2 or the base 1 to form the first guide trajectory. When the seat body 2 moves along the second moving trajectory, the axial direction of the guide shaft 51 is fixed, and it rotates circumferentially relative to the seat body 2 or the base 1 to form the second guide trajectory.

[0148] The seat body 2 and the base 1 are provided with a first guide groove and a second guide groove, which communicate with each other to form a guide groove 52. The guide shaft 51 can slide within the first guide groove and the second guide groove.
