AI Technical Summary
Existing child seat saddles are too thick when folded, making storage and transportation inconvenient. This is mainly because the locking mechanism slides and unlocks in the left and right directions, resulting in excessive thickness at the rotating connection between the seat plate and the base.
The unlocking component of the locking device slides in the front-to-back direction. The rotation of the backrest drives the locking block to disengage from the locking groove, thereby unlocking the seat plate from the base and reducing the thickness of the rotating connection.
This design makes the child seat more compact when folded, facilitating transportation and storage.

Technical Field
[0001] This utility model relates to the field of children's products, specifically to a child seat and carrier. Background Technology
[0002] Existing child seat technology includes a base, a seat plate rotatably connected to the base, and a locking element for locking the two together. The locking element is often designed to slide and unlock in the left and right direction, which results in an excessively thick connection between the base and the seat plate. This increases the thickness of the child seat when folded, making it inconvenient for storage and transportation. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a child seat.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A child seat includes a seat plate, a base, a locking device, and an unlocking component. The seat plate and the base are rotatably connected about an axis extending in a left-right direction. The locking device is used to lock the relative rotation of the seat plate and the base. The locking device includes a sliding groove, a locking block slidably disposed in the sliding groove in a front-back direction, and a locking groove. The sliding groove is provided on one of the seat plate and the base, and the locking groove is provided on the other of the seat plate and the base. The locking device has a locked state and an unlocked state. When in the locked state, the locking block is inserted into the locking groove, and the seat plate and the base are relatively fixed. When in the unlocked state, the locking block is separated from the locking groove, and the seat plate can rotate relative to the base about the axis. When switching from the locked state to the unlocked state, the unlocking component drives the locking block to slide in a front-back direction and disengage from the locking groove.
[0006] In one embodiment, the child's left and right sides also include backrests, which are rotatably connected to the seat plate around the axis. The unlocking device is disposed on the backrest. When the backrest rotates and moves closer to the seat plate around the axis, the locking device switches from the locked state to the unlocked state.
[0007] In one embodiment, when the backrest rotates a preset angle along the axis, the unlocking member abuts against the locking block, driving the locking block to move in the direction of disengaging from the locking groove;
[0008] And / or, when the backrest is close to the seat, the locking block is completely disengaged from the locking groove, and the locking device is in the unlocked state.
[0009] In one embodiment, the locking groove is disposed on the base plate, and the sliding groove is disposed on the base. When the lock state is switched to the unlock state, the lock block slides from front to back.
[0010] In one embodiment, an elastic element is further provided between the sliding groove and the locking block, the elastic element being used to provide the elastic force required to make the locking block slide toward the locking groove.
[0011] In one embodiment, the stroller further includes a front armrest, which is rotatably connected to the seat about the axis.
[0012] In one embodiment, the lock block is provided with a clearance groove, and a mating part that cooperates with the unlocking member is provided in the clearance groove. When the lock state is changed to the unlock state, the unlocking member always rotates around the axis in the clearance groove and abuts against the mating part after rotating by a preset angle.
[0013] In one embodiment, the axis passes through the unlocking member and the clearance groove.
[0014] Another objective of this invention is to provide a vehicle.
[0015] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0016] A vehicle includes a child seat and a base frame as described above, wherein the base is detachably or fixedly connected to the base frame.

Figure 1 As shown in the figure, the left direction is "front", the right direction is "back", the upper direction is "up", the lower direction is "down", and the direction perpendicular to the viewpoint is "left" and "right". The above definitions of directions are only for the convenience of describing this utility model and simplifying the description, and are not intended 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.
[0032] See Figure 1-9 As shown, the present invention relates to a stroller, which includes a child seat and a base frame 1. The stroller has the following features: Figure 1 The unfolded state shown and as Figure 9 The folded state is shown. The base frame 1 includes a front support and a rear support rotatably connected to the front support, a push rod rotatably connected to the front support and / or the rear support, and a connecting seat disposed on at least one of the front support, the rear support, and the push rod. When the trolley is used as a single-person trolley, for example, a connecting seat can be provided at the upper end of the front support or the rear support to secure the seat; when the trolley is used as a two-person trolley, for example, a connecting seat can be provided on both the front support and the push rod.
[0033] In other embodiments, the vehicle may be a trailer, a high chair, or other similar structure, and the type of chassis will vary accordingly. The child seat can be connected to the chassis via a fixed connection, a rotating connection, or a detachable connection.
[0034] The child seat includes a backrest 2, a seat 3, a base 4, a locking device, an unlocking device 5, a front armrest 6, and a footrest 7. The backrest 2 provides support for the child's back, the seat 3 provides support for the child's buttocks and legs, the front armrest 6 surrounds the front of the child for support and to prevent the child from falling out of the child seat, and the footrest 7 provides support for the child's feet and legs. The base 4 is detachably or fixedly connected to the frame 1. In this embodiment, for easy removal of the child seat, the base 4 is detachably connected to the frame 1; specifically, the base 4 is detachably connected to the connecting seat. The lower ends of the backrest 2, the rear ends of the seat 3, the base 4, and the lower ends of the front armrest 6 are rotatably connected about an axis extending in the left-right direction. The locking device is used to lock the relative rotation of the seat 3 and the base 4, and the footrest 7 is rotatably connected to the front end of the seat 3.
[0035] The locking device includes a sliding groove 81, a locking block 82 that is slidably disposed in the sliding groove 81 in the front-back direction, a locking groove 83, and an elastic element (not shown in the figure). The sliding groove 81 is provided on one of the base plate 3 and the base 4, and the locking groove 83 is provided on the other of the base plate 3 and the base 4. The elastic element is disposed between the sliding groove 81 and the locking block 82, and is used to provide the elastic force required to make the locking block 82 slide toward the locking groove 83. In this embodiment, the locking groove 83 is disposed on the base plate 3, and the sliding groove 81 is disposed on the base 4.
[0036] The locking device has a locked state and an unlocked state, such as Figure 3-4 As shown, when in the locked state, the locking block 82 is inserted into the locking groove 83, and the seat plate 3 and the base 4 are relatively fixed. At this time, the child seat can be used by a child. Figure 7-9 As shown, when in the unlocked state, the locking block 82 separates from the locking groove 83, and the seat plate 3 can rotate relative to the base around its axis. At this time, the seat plate 3 of the child seat can move closer to the base 4, thereby converting the child seat into a folded state. Figure 5-6As shown, when transitioning from the locked state to the unlocked state, the unlocking component 5 drives the locking block 82 to slide in the front-to-back direction and disengage from the locking groove 83. Specifically, in this embodiment, the unlocking component 5 is disposed on the backrest 2, and the locking block 82 has a clearance groove 821. The clearance groove 821 is eccentrically positioned relative to the axis, and the axis passes through the unlocking component 5 and the clearance groove 821. A mating part 822 that cooperates with the unlocking component 5 is provided in the clearance groove 821. When transitioning from the locked state to the unlocked state, the backrest 2 rotates relative to the seat plate 3 around the axis, specifically counterclockwise. The unlocking component 5 always rotates around the axis within the clearance groove 821. After the backrest 2 rotates a certain angle, the unlocking component 5 abuts against the mating part 822, driving the locking block 82 to slide from front to back, causing the unlocking component 5 to disengage from the locking groove 83.
[0037] Therefore, when it is necessary to fold the stroller of this utility model, the backrest 2 is rotated closer to the seat plate 3, and rotated to the position as described above. Figure 5-6 In the state shown, the unlocking element 5 contacts and engages with the mating part 822, driving the locking block 82 to slide from front to back within the sliding groove 81. The elastic element is compressed and deformed, ultimately as shown... Figure 7-8 As shown, the locking block 82 completely disengages from the locking groove 83, and the seat plate 3 and the base 4 are relatively unlocked. When the backrest 2 rotates to contact the seat plate 3, the backrest 2 pushes the seat plate 3 to rotate relative to the base frame and move closer together, ultimately achieving the desired effect. Figure 9 In the folded state shown, when the stroller is unfolded, the backrest 2 rotates clockwise around the axis relative to the seat 3. When the unlocking element 5 no longer abuts against the locking block 82, the locking block 82 enters the locking groove 83 under the action of the elastic force of the elastic element, thus completing the locking of the backrest 2 and the seat 3.
[0038] The stroller of this utility model uses the action of the backrest 2 rotating and moving closer to the seat plate 3 to unlock the locking device, so that the seat plate 3 and the base 4 can rotate relative to each other. After unlocking, the backrest 2 can move the seat plate 3 further closer to the base 4, making it easier to fold the child seat and fold it more compactly.
[0039] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
