Description

Technical Field

[0001] This utility model relates to the field of child car safety seats, and more particularly 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 and moved a certain distance before placing the child. However, this rotation causes a slight offset between the seat and the base, requiring sufficient space for rotation and offering limited stability, impacting the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a safety seat that reduces the space occupied by the safety seat in the car, makes it easier for users to put children in and take them out of the safety seat, and makes it easier for users to take care of children in the car.

[0004] To achieve this objective, the present invention adopts the following technical solution: the safety seat includes:

[0005] Base;

[0006] A support member is disposed on the base and located above the base;

[0007] The seat body has a first position and a second position relative to the base;

[0008] An actuating structure is disposed between the seat body and the support member. The actuating structure includes a first shaft and a second shaft disposed on one of the seat body and the support member, and a first guide structure and a second guide structure disposed on the other of the seat body and the support member. The first shaft is slidably disposed within the first guide structure, and the second shaft is slidably disposed within the second guide structure.

[0009] When the seat body rotates from the first position to the second position, the first axis slides along the first guide structure, the second axis slides along the second guide structure, and in the second position, the central axis of the seat body is offset in the left-right direction from the central axis of the seat body when it is in the first position.

[0010] Furthermore, in the first position, along the front-rear direction, the second shaft is located relatively close to the rear side of the seat body; the second shaft is also located relatively close to the rear side of the support member;

[0011] When moving to the second position, the second axis moves relative to the rear side of the support member, while the first axis moves relative to the left and right direction.

[0012] Furthermore, in the second position, the second axis is positioned close to the center of the support member in the front-rear direction.

[0013] Furthermore, in the first position, the first shaft is positioned relative to the center of the support member in the front-rear direction;

[0014] In the second position, the first shaft is positioned close to the left-right edge of the support.

[0015] Furthermore, in the first position, the first shaft and the second shaft are arranged in the front-rear direction, with the second shaft located behind the first shaft; the first shaft is opposite to the center position of the support member in the front-rear direction, and the second shaft is opposite to the center position of the support member in the front-rear direction.

[0016] Furthermore, both the first shaft and the second shaft are disposed on the seat body, and both the first guide structure and the second guide structure are disposed on the support member;

[0017] The second guide structure extends in the front-to-back direction and has a front end and a rear end that are positioned opposite each other in the front-to-back direction; the first guide structure has a left end and a right end that are positioned opposite each other in the left-to-right direction and are located opposite each other on both sides of the support member;

[0018] In the first position, the first shaft is located at the center of the first guide structure in the left-right direction.

[0019] Furthermore, when the first position changes to the second position, the first axis moves toward the left end;

[0020] The position of the first axis in the second position is opposite to its position in the first position in the left-right direction.

[0021] Alternatively, the first shaft in the second position is closer to the rear side of the base than it was in the first position; in the second position, the distance between the first shaft and the rear side of the base is less than the distance between the second shaft and the rear side of the base.

[0022] Furthermore, the first guide structure extends in the left-right direction;

[0023] Alternatively, the first guide structure is curved as a whole. From the center of the first guide structure to the left end, the first guide structure includes a first arc segment and a second arc segment arranged in sequence. The first arc segment is circular, and the radius of the circle containing the first arc segment is equal to the distance between the first axis and the second axis, so that when in the first arc segment, the first axis rotates around the second axis as the center.

[0024] Furthermore, the curvature of the second arc segment is less than that of the first arc segment, and the radius of curvature of the second arc segment is greater than the distance between the first axis and the second axis, so that when moving along the second arc segment, the first axis slides within the first guide structure and the second axis slides within the second guide structure.

[0025] Furthermore, the seat body also has a third position, the second position and the third position are symmetrically arranged, and the seat body rotates relative to the base between the first position and the third position via the actuation structure; when the seat body is in the third position, the central axis of the seat body is offset in the left and right direction from the central axis of the seat body when it is in the first position;

[0026] When the first position changes to the second position, the first shaft moves toward the left end; when the first position changes to the third position, the first shaft moves toward the right end; the orientation of the seat body when it is in the second position is opposite to the orientation of the seat body when it is in the third position.

[0027] Alternatively, when the first position changes to the second position, the first axis moves toward the right end; when the first position changes to the third position, the first axis moves toward the left end.

[0028] In the first position, the second shaft is located at the rear end; in the second position, the second shaft slides along the second guide structure to the front end.

[0029] In the first position, the first shaft is located at the center of the first guide structure in the left-right direction, and the left end and the right end are symmetrically arranged with respect to the center of the first guide structure. In the second position, the first shaft slides along the first guide structure to the left end or the right end.

[0030] The seat body also has a third position, in which the first shaft moves to the right end when the first shaft moves to the left end in the second position;

[0031] When the first axis moves to the right end in the second position, it moves to the left end in the third position.

[0032] Furthermore, the support member is rotatably mounted on the base;

[0033] A first base plate is fixedly provided on the support member, and a second base plate is fixedly provided on the base. The first base plate and the second base plate are rotatably connected, and the first base plate can rotate 360° around the circumference relative to the second base plate.

[0034] The first base plate is provided with a rotating shaft. One end of the rotating shaft is connected to the first base plate, and the other end of the rotating shaft passes through the second base plate. A limiting ring is fitted on the other end of the rotating shaft, and the limiting ring contacts the second base plate. The rotating shaft can rotate relative to the second base plate.

[0035] The beneficial effects of this utility model are:

[0036] The safety seat provided by this utility model has the following characteristics: When the seat body moves from the first position to the second position, the central axis of the seat body in the second position is offset in the first direction from the central axis of the seat body in the first position. The seat body can extend outward relative to the base. 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. When the seat body is in the second position, the central axis of the seat body does not deviate from the central axis of the seat body in the first position in the second direction. The seat body does not have a certain amount of offset in the front-back direction relative to the base when in the second position. It does not require the user to provide enough space for the installation of the safety seat in order to achieve the rotation of the seat body. Attached Figure Description

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0058] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0060] In the description of this embodiment, the terms "upper," "lower," "right," "front," and "rear," etc., referring to directions or positional relationships, are 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. Their purpose is solely to clearly illustrate the relative positional relationships of the components within the car seat, and not to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.

[0061] like Figures 1 to 4 As shown, this embodiment provides a child safety seat for installation in a car seat for infants and toddlers. The safety seat includes a base 1, a support member 3, a seat body 2, and an actuating structure. The support member 3 is disposed on the base 1 and located above the base. The seat body 2 has a first position and a second position relative to the base 1. An actuating structure is provided between the seat body 2 and the support member 3, and the actuating structure is used to rotate the seat body 2 relative to the base 1 between the first position and the second position.

[0062] When the seat body 2 rotates from the first position to the second position, the central axis of the seat body 2 is offset from the central axis a when the seat body 2 is in the first position in the first direction. 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 body 2 is offset from the central axis of the seat body 2 in the left and right direction in the first position, thereby realizing that the seat body 2 can move along the left and right sides during the rotation, thereby better realizing the use of the safety seat and making it convenient for children to sit in the safety seat and be taken out.

[0063] The seat body 2 has a seating space. When the seat body 2 is in the first position, the seating space is positioned facing forward or backward. When the seat body 2 is in the second position, the seating space faces to the left or right.

[0064] The seat body 2 includes a support member 20 and a support main body. The support member 20 is connected to the support member 3, and the support main body is connected to the support member 20. The support main body and the support member 20 can be integrally set or separately set. If the support main body and the support member 20 are separately set, they can be assembled or disassembled, and different support main bodies can be selected according to usage needs. In this embodiment, the first shaft 41 and the second shaft 51 are both set on the support member 20 and located at the bottom of the support member 20. It can be understood that when the first shaft 41 and the second shaft 51 are set on the support member 3, the first guide structure 42 and the second guide structure 52 are set on the support member 20 and located at the bottom of the support member 20.

[0065] In a specific embodiment, both the first guide structure 42 and the second guide structure 52 can be grooves disposed on the support member 20. The first guide structure 42 is a first groove, and the second guide structure 52 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 edge of the second groove. This structural arrangement can prevent mutual interference when the first shaft 41 and the second shaft 51 slide within their respective guide structures.

[0066] The supporting body can be Figure 1 and Figure 2 The car seat 21 shown is designed for use with older children. Figure 1 The image shows the safety seat 21 in the first position, facing forward. Figure 2 The image shows the car seat 21 in the second position, facing rearward. The carrier can also be an infant carrier for use with younger infants and toddlers.

[0067] like Figure 4 and Figure 5As shown, the seat body 2 also has a third position symmetrical to the second position. The seat body 2 rotates relative to the base 1 between the first position and the third position via an actuating structure. The orientation of the seat body 2 when it is in the second position is opposite to the orientation of the seat body 2 when it is in the third position. For example, if the orientation of the bearing space of the seat body 2 when it is in the second position is to the left, then the orientation of the bearing space of the seat body 2 when it is in the third position is to the right; if the orientation of the bearing space of the seat body 2 when it is in the second position is to the right, then the orientation of the bearing space of the seat body 2 when it is in the third position is to the left.

[0068] When the seat body 2 is in the third position, its central axis a is offset in the first direction from the central axis a when it is in the first position, but does not offset in the second direction. In the third position, the seat body 2 can extend outward relative to the base 1, eliminating the need for the user to bend over or reach into the car when placing or removing a child from it, making it more convenient. Furthermore, the seat body 2 does not shift in the fore-and-aft direction relative to the base 1 in the third position, eliminating the need for the user to provide sufficient space for the installation of the child safety seat to allow for rotation of the seat body 2.

[0069] By setting the second and third positions, the installation position of the child safety seat is not limited. That is, the child safety seat can be installed near the left or right door, and the seat body 2 can extend outward relative to the base 1, which improves the flexibility of the use of the child safety seat.

[0070] Reference Figure 4 , Figure 5 and Figure 6 As shown, the actuation structure includes a first shaft 41 and a second shaft 51 disposed on one of the seat body 2 and the support member 3. The actuation structure also includes a first guide structure 42 and a second guide structure 52 disposed on the other of the seat body 2 and the support member 3. The first shaft 41 is slidably disposed in the first guide structure 42, and the second shaft 51 is slidably disposed in the second guide structure 52.

[0071] When the seat body 2 rotates from the first position to the second position, the first shaft 41 slides along the first guide structure 42, the second shaft 51 slides along the second guide structure 52, and in the second position, the central axis of the seat body 2 is offset in the left and right direction from the central axis of the seat body 2 when it is in the first position.

[0072] Both the first guide structure 42 and the second guide structure 52 are grooves, one of which is a sliding groove and the other is a guide groove. Through the sliding of the two grooves and the two shafts, the seat body 2 can slide synchronously during rotation, so that the seat body 2 can be offset from the base 1, making it easier to use the seat body 2.

[0073] In this embodiment, the first shaft 41 and the second shaft 51 are axially fixed to the seat body 2 and can rotate circumferentially relative to the seat body 2 or the base 1. The first shaft 41 can be rotatably mounted on the seat body 2 or fixed to the seat body 2. The first shaft 41 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 shaft 41 can rotate circumferentially within the first guide structure 42. The second shaft 51 has the same structure as the first shaft 41, and will not be described in further detail here.

[0074] In this embodiment, in the first position, the second shaft 51 is located relatively close to the rear side of the support member 3 in the front-back direction.

[0075] The second shaft 51 can be fixed to the seat body 2 or to the base 1. In this embodiment, the second shaft 51 is fixed to the seat body 2 as an example.

[0076] By positioning the second shaft 51 relatively close to the rear side of the seat body 2, the seat body 2 can swing around the second shaft 51 during rotation, thus causing the entire seat body 2 to shift laterally more during rotation. It can be understood that the closer the second shaft 51 is to the center of the seat body 2, the less the seat body 2 will deflect outwards during rotation. When the second shaft 51 is located at the center of the seat body 2, the seat body 2 can only rotate circumferentially and will not experience lateral shift.

[0077] Understandably, after the seat body 2 is installed and fixed on the support 3, the second shaft 51 is also located relatively close to the rear side of the support 3. It should be noted that "close to the rear side of the seat body 2" here is compared to "close to the front side of the seat body 2". The seat body 2 is generally located in the area between the center of the seat body 2 and the rear side of the seat body.

[0078] When moving to the second position, the second shaft 51 moves relative to the rear side away from the support member 3, and the first shaft 41 moves relative to the left and right direction.

[0079] When the seat body 2 moves to the second position, the position of the second shaft 51 is close to the center of the support member 3 in the front-rear direction.

[0080] As the seat body 2 rotates and moves, the second shaft 51 moves along the second guide structure 52 and relatively forward. The second shaft 51 moves to a position close to the center of the seat body 2, thereby providing better support stability for the seat body 2 as it slides laterally. This structural arrangement ensures that when the seat body 2 deflects around the second shaft 51, the second shaft 51 moves towards the center of the seat body 2, preventing the seat body 2 from moving to the edge area of ​​the support member 3 after rotation, thus avoiding a decrease in stability.

[0081] It is understandable that in order to move the second shaft 51 to a position close to the center of the support member 3 in the front-back direction, one end of the second guide structure 52 will extend to a position close to the center of the support member 3 in the front-back direction.

[0082] It should be noted that the specific shape of the extended second guide structure 52 is not further limited. The second guide structure 52 can be extended as a whole, and its shape can be straight or curved. Of course, in other embodiments, the extended shape of the second guide structure 52 can also be set as a broken line. The curved second guide structure can be a single arc or formed by multiple arcs.

[0083] In the first position, the first shaft 41 is positioned relative to the center of the support member 3 in the front-rear direction;

[0084] In the second position, the first shaft 41 is positioned close to the edge of the support 3 in the left-right direction.

[0085] In the first position, positioning the first shaft 41 at the center of the support member 3 in the front-rear direction allows sufficient space for the seat body 2 to slide along the support member 3. The area at the center of the support member 3 in the front-rear direction has a wider dimension in the left-right direction, thus providing ample space for the relative sliding of the seat body 2 on the support member 3. Similarly, in the second position, designing the first shaft 41 to be located relative to the edge of the support member 3 in the left-right direction also provides as much space as possible for the movement of the seat body 2.

[0086] When the seat body 2 is in the second position, the central axis a of the seat body 2 does not deviate from the central axis a of the seat body 2 in the first position in the front-back direction. That is, in the second position, the central axis of the seat body 2 is opposite to the central axis of the seat body 2 in the first position in the left-right direction. The seat body 2 does not have a certain amount of offset relative to the base 1 in the front-back direction in the second position. This structural design does not require the user to provide sufficient space for the installation of the child safety seat in order to allow the seat body 2 to rotate.

[0087] In the first position, the first shaft 41 and the second shaft 51 are arranged in the front-back direction, the first shaft 41 and the second shaft 51 are opposite each other in the front-back direction, and the second shaft 51 is located behind the first shaft 41.

[0088] The first shaft 41 is opposite to the center position of the support member 3 in the front-rear direction, and the second shaft 51 is opposite to the center position of the support member 3 in the front-rear direction. The fact that the first shaft 41 and the second shaft 51 are opposite to the center position of the support member 3 in the front-rear direction allows the seat body 2 to rotate symmetrically to the left and right, thereby making it easier to install and use the child safety seat in the vehicle.

[0089] Of course, in other embodiments, the first axis 41 and the second axis 51 can also be offset from the center position of the support member 3 in the front-back direction. This structure can also enable the seat body 2 to rotate in two directions, but different offset effects will be produced when rotating to the left and right, resulting in a poor user experience.

[0090] In this embodiment, the seat body 2 can rotate from a first position to a second or third position. The seat body 2 will not move axially along the first shaft 41 or the second shaft 51, ensuring the stability of the seat body 2's rotation. Furthermore, the seat body 2 and the support member 3 are connected via the first shaft 41 and the second shaft 51, resulting in a simple connection structure. The direct fit between the shaft grooves facilitates installation and reduces the number of parts used, thus saving costs.

[0091] The second guide structure 52 extends in the front-back direction and has a front end 521 and a rear end 522 that are opposite to each other in the front-back direction; the first guide structure 42 has a left end 421 and a right end 422 that are opposite to each other, the left end 421 and the right end 422 being opposite to each other in the left-right direction and located opposite to each other on both sides of the support member 3.

[0092] In the first position, the first shaft 41 is located at the center of the first guide structure 42 in the left-right direction.

[0093] The first shaft 41 is located at the center 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 opposite each other in the left-right direction, so that when the first position is changed to the second position, the first shaft 41 is symmetrical whether it moves to the left end 421 or to the right end 422.

[0094] When the first position changes to the second position, the first shaft 41 moves toward the left end 421; various safety seats can be provided depending on the arrangement of the first guide structure 42.

[0095] The first type of car seat, such as Figure 7As shown, the position of the first shaft 41 in the second position is opposite to its position in the first position in the left-right direction; when the first shaft 41 slides along the first guide structure 42, the starting position of the first shaft 41 is arranged in the left-right direction and is located on a straight line extending in the left-right direction.

[0096] The first guide structure 42 can be a straight groove that extends in the left and right direction. The extended shape of the first guide structure 42 can also be a curve or a broken line.

[0097] The second type of car seat, such as Figure 10 As shown, when transitioning from the first position to the second position, the first shaft 41 moves toward the left end 421; the position of the first shaft 41 in the second position is closer to the rear side of the base 1 than its position in the first position. In the second position, the distance between the first shaft 41 and the rear side of the base 1 is less than the distance between the second shaft 51 and the rear side of the base 1.

[0098] The aforementioned structure requires that in the first position, the distance between the first axle 41 and the rear side of the base 1 is L1, and in the second position, the distance between the first axle 41 and the rear side of the base 1 is L2, where L2 is greater than L1. This means that when moving to the second position, the first axle 41 moves rearward a certain distance compared to the first position. Furthermore, the first axle 41 moves rearward beyond the position of the second axle 51 in the second position. This structural arrangement causes the line connecting the first axle 41 and the second axle 51 in the second position to tilt rearward relative to the left-right direction, making the seating space more rearward when the seat body 2 rotates to the left, thus facilitating the use of the seat body 2. Currently, most locomotive doors open to the side, and the door does not open perpendicular to the forward direction of the vehicle body, but rather towards the rear of the vehicle body. The aforementioned structure of the safety seat better matches the opening angle of the door, resulting in a better experience after the safety seat is installed and secured.

[0099] For the second type of child safety seat, such as Figure 10-11 As shown, 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 circular, and the radius of the circle in which the first arc segment 4201 is located is equal to the distance between the first axis 41 and the second axis 51, so that when the first arc segment 4201 is in place, the first axis 41 rotates around the second axis 51 as the center.

[0100] Therefore, the curvature of the second arc segment 4202 is less than the curvature of the first arc segment 4201, and the radius of curvature of the second arc segment 4202 is greater than the distance between the first axis 41 and the second axis 42, so that when moving along the second arc segment 4202, the first axis 41 slides within the first guide structure 42, and the second axis 51 slides within the second guide structure 52.

[0101] It is understood that in other embodiments, a third arc segment and a fourth arc segment may also be provided between the second arc segment 4202 and the left end 421.

[0102] Of course, the first arc segment 4201 and the second arc segment 4202 can also be replaced with straight lines, so that the overall extended shape of the first guide structure 42 is formed by multiple broken lines.

[0103] In this embodiment, the curvature changes of the first arc segment 4201 and the second arc segment 4202 are relatively small, so that the entire first guide structure 42 is arc-shaped, and the first guide structure 42 arches in the direction away from the second guide structure 51, while the first guide structure 42 arches in the direction towards the rear side of the base.

[0104] In this embodiment, during the initial rotation, the seat body 2 will first rotate around the second axis 51 as the center. At this time, the second axis 51 is located near the rear end 522. At this time, the first axis 41 slides within the first arc segment 4201. When the first axis 41 slides to the second arc segment 4202, the second axis 51 slides along the second guide structure 52 towards the front end 521. When the second axis 51 slides, it pushes the seat body 2 to deflect to the left or right. The above structure can make the seat body 2 have a larger deflection amount when it deflects, and the use process will be smoother.

[0105] The seat body also has a third position, the second position and the third position are symmetrically arranged, the seat body 2 rotates relative to the base 1 between the first position and the third position via the actuation structure; when the seat body 2 is in the third position, the central axis of the seat body 2 is offset in the left and right direction from the central axis of the seat body 2 when it is in the first position;

[0106] When the first position changes to the second position, the first shaft 41 moves toward the left end 421; when the first position changes to the third position, the first shaft 41 moves toward the right end 422; the orientation of the seat body 2 when it is in the second position is opposite to the orientation of the seat body 2 when it is in the third position.

[0107] In other embodiments, the following design may also be implemented: when the first position changes to the second position, the first shaft 41 moves toward the right end 422; when the first position changes to the third position, the first shaft 41 moves toward the left end 421.

[0108] In the first position, the second shaft 51 is located at the rear end 522; in the second position, the second shaft 51 slides along the second guide structure 52 to the front end 521.

[0109] In the first position, the first shaft 41 is located at the center of the first guide structure 42 in the left-right direction, and the left end 421 and the right end 422 are symmetrically arranged with respect to the center of the first guide structure 42. In the second position, the first shaft 41 slides along the first guide structure 42 to the left end 421 or the right end 422.

[0110] The seat body also has a third position, in which the first shaft 41 moves to the left end 421 when it is in the second position, and in the third position, the first shaft 41 moves to the right end 422.

[0111] When the first shaft 41 moves to the right end 422 in the second position, it moves to the left end 421 in the third position.

[0112] When the seat body 2 changes from the first position to the second position, the first shaft 41 slides in the first guide structure 42 toward the left end 421, and the seat body 2 rotates from a forward-facing position to a left-facing position. The second shaft 51 moves along the second guide structure 52 from the rear end 522 toward the front end 521.

[0113] When the seat body 2 changes from the first position to the third position, the first shaft 41 slides towards the right end 422 within the first guide structure 42, and the seat body 2 rotates from a forward-facing orientation to a right-facing orientation. The second shaft 51 moves along the second guide structure 52 from the rear end 422 towards the front end 421.

[0114] In the second type of child safety seat described above, the seat body 2 is installed facing forward during use. For the other type of seat body 2, which is installed facing backward during use, such as... Figure 12 As shown, its first guide structure 42 is also curved as a whole, and the second guide structure 52 is straight as a whole. The front end of the second guide structure 52 is positioned relatively close to the front side of the base 1. The second guide structure 52 is arc-shaped and arches in the direction away from the first guide structure 42. In this method, its movement process is similar to that of the second type of safety seat. The only difference between the two is that the seat installation and use methods are different, resulting in different offsets during rotation. This will not be elaborated in detail here.

[0115] When the seat body 2 is in the first position, the center lines of the first shaft 41 and the second shaft 51 are perpendicular to and intersect with the longitudinal axis M1 of the base 1, that is, the first shaft 41 and the second shaft 51 are collinear.

[0116] In a specific embodiment, such as Figure 5 , Figure 6 and Figure 7 As shown, both the first guide structure 42 and the second guide structure 52 are straight grooves. The first guide structure 42 extends along a first direction, and the second guide structure 52 extends along a second direction. The second guide structure 52 is disposed on one side of the first guide structure 42. The first shaft 41 slides within the first guide structure 42, and the second shaft 51 slides within the second guide structure 52.

[0117] While the seat body 2 rotates from the first position to the second or third position, the seat body 2 can extend outward relative to the base 1 at the second or third position, making it convenient for the user to place the child on the seat body 2 or remove the child from the seat body 2, without the user having to bend over or reach into the car.

[0118] Optionally, the second guide structure 52 is perpendicular to the first guide structure 42, and the second guide structure 52 is disposed at the rear end of the seat body 2 or the support member 3, with the first guide structure 42 symmetrically arranged relative to the second guide structure 52. When the seat body 2 is in the first position, the second shaft 51 is located at the end of the second guide structure 52 away from the first guide structure 42, and the groove wall of the second guide structure 52 limits the position of the second shaft 51. The first shaft 41 is located in the middle position of the first guide structure 42, and the groove wall of the first guide structure 42 limits the first shaft 41 in the first direction, ensuring that the seat body 2 in the first position will not be displaced in the second direction. During the rotation of the seat body 2 from the first position to the second position, the first shaft 41 slides within the first guide structure 42 located on one side of the second guide structure 42. During the rotation of the seat body 2 from the first position to the second position, the second shaft 51 slides within the first guide structure 42 located on the other side of the second guide structure 52. Therefore, the first guide structure 42 is symmetrically arranged with respect to the second guide structure 52, ensuring that the first movement trajectory and the second movement trajectory are the same, that is, the two rotational positions of the seat body 2 are symmetrical. When the seat body 2 rotates to the second position or the third position, the end sidewall of the first guide structure 42 acts as a limit for the first shaft 41, that is, it limits the position in which the seat body 2 extends outward relative to the base 1.

[0119] In some other feasible solutions, the second guide structure 52 is perpendicular to the first guide structure 42, and the second guide structure 52 is disposed at the front end of the seat body 2 or the support member 3, and the first guide structure 42 is symmetrically disposed with respect to the second guide structure 52.

[0120] In a specific embodiment, when the seat body 2 rotates from the first position to the second position, it forms a first moving trajectory, and the seat body 2 can rotate continuously relative to the base 1 along the first moving trajectory. When the seat body 2 rotates from the first position to the third position, it forms a second moving trajectory. Both the first and second moving trajectories are curves, and the seat body 2 can rotate continuously relative to the base 1 along the second moving trajectory. Further optionally, the second moving trajectory does not intersect with the first moving trajectory, and the seat body 2 remains in the same plane when moving along both the first and second moving trajectories. The seat body 2 will not fluctuate in a direction perpendicular to the horizontal plane during rotation, ensuring the stability of the seat body 2's rotation. Furthermore, since the second and first moving trajectories do not intersect, during rotation to the second position, the seat body 2 will not move within the second moving trajectory; the seat body 2 can only rotate to the second position. Similarly, during rotation to the third position, the seat body 2 will not move within the first moving trajectory; the seat body 2 can only rotate to the third position. This improves the controllability of the seat body 2's rotation position and prevents the seat body 2 from swaying between the first and second moving trajectories during rotation.

[0121] When the seat body 2 moves along the first or second movement trajectory, the first shaft 41 and the second shaft 51 are axially fixed and rotate circumferentially relative to the seat body 2 or the base 1, respectively. The seat body 2 can rotate from the first position to the second or third position. The seat body 2 will not move along the axial direction of the first shaft 41 or the second shaft 51, ensuring the stability of the rotation of the seat body 2. The seat body 2 and the support 3 are connected through the first shaft 41 and the second shaft 51, and the connection structure is simple.

[0122] In this embodiment, the support member 3 allows the seat body 2 to rotate 360° around the base 1 to any position, so as to facilitate the 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.

[0123] The support member 3 allows the seat body 2 to rotate 360° circumferentially relative to the base 1 to any position. In some embodiments, such as... Figure 8 and Figure 9 As shown, a first base plate 7 is fixedly provided on the support member 3, and a second base plate 8 is provided on the base 1. The first base plate 7 and the second base plate 8 are rotatably connected, and the first base plate 7 can rotate 360° around the second base plate 8 to any position.

[0124] Optionally, a rotating shaft is provided on the first base plate 7. One end of the rotating shaft is connected to the first base plate 7, and the other end of the rotating shaft passes through the second base plate 8. A limiting ring 6 is fitted onto the other end of the rotating shaft, and the limiting ring 6 contacts the second base plate 8, allowing the rotating shaft to rotate relative to the second base plate 8. Optionally, the limiting ring 6 is rotatably connected to the second base plate 8, and the rotating shaft is fixedly connected to the limiting ring 6. The limiting ring 6 reduces wear on the rotating shaft. Alternatively, the limiting ring 6 is fixedly connected to the second base plate 8, and the rotating shaft is rotatably connected to the limiting ring 6. The limiting ring 6 also reduces wear on the second base plate 8.

[0125] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
