[0040] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0041] In the following description, the directions such as "front", "back", "left", "right", "up", and "down" are all based on Figure 1 , the left side direction in the figure is "front", the right side direction is "back", the upper side direction is "up", the lower side direction is "down", and the directions perpendicular to the paper plane in the figure are "left" and "right". The definitions of the above directions are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the utility model.
[0042] like Figure 1 to Figure 22 As shown, the seat mechanism of the present invention comprises a support seat 1 and a seat body 2. The seat body 2 is rotatably arranged on the support seat 1 around a rotating shaft extending in the up-down direction.
[0043] like Figure 1 As shown, the seat body 2 includes a seat portion 21 for supporting the child's buttocks and a backrest 22 for supporting the child's back, and the lower portion of the backrest 22 is connected to one end of the seat portion 21. The seat portion 21 is rotatably connected to the support seat 1 through a rotating shaft.
[0044] The seat mechanism has a first position and a second position. In this embodiment, when the seat mechanism is in the first position, the seat portion 21 is located in front of the backrest portion 22, and when a child sits in the seat body 2, the child's face faces forward. Figure 1 and Fig.10 When the seat mechanism is in the second position, the seat portion 21 is located behind the backrest portion 22, and when a child sits in the seat body 2, the child's face faces backward. The seat body 2 rotates relative to the support seat 1 around the rotation axis, so that the seat mechanism can be switched between the first position and the second position.
[0045] In other embodiments, the child's face may also be facing left or right when the seat mechanism is in the first position or the second position.
[0046] The seat mechanism further includes a locking mechanism, and when the seat mechanism is in the first position or the second position, the locking mechanism is in a locked state, thereby locking the relative position of the seat body 2 and the support seat 1 through the locking mechanism, so that the seat body 2 cannot rotate relative to the support seat 1. When the locking mechanism is in an unlocked state, the seat body 2 can rotate relative to the support seat 1, so that the seat mechanism is switched between the first position and the second position.
[0047] The seat mechanism further includes a limiting assembly, which includes a first limiting member 3 and a second limiting member 4. The first limiting member 3 is fixedly arranged on one of the support seat 1 and the seat body 2, and the second limiting member 4 is fixedly arranged on the other of the support seat 1 and the seat body 2. In this embodiment, the first limiting member 3 is arranged at the bottom of the seat body 2, and the second limiting member 4 is arranged on the support seat 1. Figure 2 to Figure 5 shown.
[0048] When the seat mechanism deviates from the first position and the second position, the first limiting member 3 and the second limiting member 4 are disengaged.
[0049] When the seat mechanism switches to the first position or the second position, when the seat body 2 rotates relative to the support seat 1 to make the first limit member 3 cooperate with the second limit member 4, it means that the seat body 2 is rotated into place and the seat mechanism is in the first position or the second position.
[0050] When the seat mechanism is in the first position and the second position, due to the cooperation of the first limiter 3 and the second limiter 4, the seat body 2 shakes less relative to the support seat 1, so that the seat mechanism is more comfortable and safer when used.
[0051] Specifically, Figure 2 and Figure 3 As shown, the first stopper 3 is a convex portion provided on the seat portion 21. Figure 4 and Figure 5 As shown, the second stopper 4 is arranged on an end surface of the support seat 1 facing the seat body 2, and a concave portion 41 matching with the convex portion is arranged on the second stopper 4. In this embodiment, the concave portion 41 extends from the top of the second stopper 4 to the bottom of the second stopper 4.
[0052] like Figure 4 and Figure 5 As shown, the recess 41 has two first side walls 411 arranged opposite to each other, and the two first side walls 411 are respectively located in different rotation directions of the seat body 2 relative to the support seat 1, and at least one first side wall 411 is an inclined surface, which extends obliquely from the bottom of the recess 41 to the top of the recess 41 and toward the outer side of the recess 41. The inclined surface can be a straight surface, an arc surface, or a combination of a straight surface and an arc surface.
[0053] like Figure 4 and Figure 5 As shown, the second position-limiting member 4 has two second side walls 42 arranged opposite to each other, the recess 41 is located between the two second side walls 42, the two second side walls 42 are respectively located in different rotation directions of the seat body 2 relative to the support seat 1, and at least one second side wall 42 is an inclined surface, which extends from the bottom of the second position-limiting member 4 to the top of the second position-limiting member 4 and in a direction close to the recess 41. The inclined surface can also be a straight surface, an arc surface, or a combination of a straight surface and an arc surface. Among them, the first position-limiting member 3 and the seat portion 21 can be arranged as one body or as two bodies. Similarly, the second position-limiting member 4 and the support seat 1 can be arranged as one body or as two bodies.
[0054] In other embodiments, the second limiting member 4 may not have the second side wall 42 , and the first side wall 411 extends obliquely downward from the surface of the supporting seat 1 to form the recess 41 .
[0055] The seat body 2 can also be slidably arranged relative to the support seat 1 along the axial direction of the rotating shaft, so that the first stopper 3 can enter or disengage from the second stopper 4. In other embodiments, the seat body 2 is only rotatably arranged along the rotating shaft relative to the support seat 1, and at least one of the first stopper 3 and the second stopper 4 is elastic, and the first stopper 3 and the second stopper 4 are matched or disengaged by extrusion deformation.
[0056] At least two groups of limit assemblies are provided, and at least two groups of limit assemblies are evenly spaced along the circumferential direction of the rotation of the seat body 2. In this way, when the seat mechanism is in the first position or the second position, the seat body 2 is not easy to tilt, so that the stability of the seat mechanism is better when used.
[0057] Preferably, when the seat mechanism is in the first position or the second position, the limiting components are symmetrically arranged at the front and rear of the seat mechanism. Of course, the limiting components can also be symmetrically arranged at the left and right of the seat mechanism. Alternatively, a group of limiting components are respectively arranged at the front, rear, left and right of the seat mechanism, the limiting components at the front and rear are symmetrically arranged, the limiting components at the left and right are symmetrically arranged, and the distances between the limiting components at the front and rear and the axis center line of the rotating shaft are different from the distances between the limiting components at the left and right and the axis center line of the rotating shaft. This arrangement makes the shaking of the seat body 2 relative to the support seat 1 smaller, and makes the stability of the seat mechanism better in use. Moreover, when the seat mechanism changes direction, the rotation of the seat body 2 is smoother, and there will be no jamming when rotating about 90 degrees.
[0058] When the seat mechanism is in the first position or the second position, the first stopper 3 cooperates with the second stopper 4, the convex portion is located in the concave portion 41, and the convex portion 41 abuts against the bottom of the concave portion 41, as shown in FIG. Figure 6 , Figure 7 and Fig. 9 shown.
[0059] The process of the seat mechanism switching between the first position and the second position is as follows:
[0060] After the locking mechanism is unlocked, force is applied to the seat body 2 to make it rotate relative to the support base 1 around the rotation axis.
[0061] When the seat body 2 rotates, the convex portion abuts against the first side wall 411 and gradually moves from the bottom to the top of the concave portion 41 along the first side wall 411. During this process, the seat body 2 slides upward relative to the support seat 1 along the axis of the rotating shaft until the convex portion moves to the top of the concave portion 41. Figure 12 to Figure 14 shown.
[0062] When the seat body 2 continues to rotate in the current direction until the convex portion corresponds to the position of the second side wall 42, as the seat body 2 rotates, the seat body 2 slides downward relative to the support seat 1 under the action of its own gravity, so that the convex portion abuts against the second side wall 42. Figure 16 to Figure 18 As shown, the seat body 2 is gradually moved from the top to the bottom of the second stopper 4 along the second side wall 42 until the first stopper 3 is rotated away from the second stopper 4. Figure 20 to Figure 22 shown.
[0063] When the seat body 2 continues to rotate relative to the support seat 1 until the first limit member 3 approaches the second limit member 4 again, the protrusion abuts against the second side wall 42 and gradually moves from the bottom to the top of the second limit member 4 along the second side wall 42. During this process, the seat body 2 slides upward relative to the support seat 1 until the protrusion moves to the top of the second limit member 4, that is, the top of the recess 41.
[0064] The seat body 2 continues to rotate in the current direction, and the convex part moves to the position of the concave part 41, and the convex part abuts against the first side wall 411, and gradually moves from the top to the bottom of the concave part 41 along the first side wall 411. In this process, the seat body 2 slides downward relative to the support seat 1 until the convex part moves to abut against the bottom of the concave part 41. At this time, it is prompted that the seat mechanism has been reversed.
[0065] Preferably, the height of the convex portion is greater than the depth of the concave portion 41. In this way, when the seat mechanism is in the first position and the second position and the convex portion is located in the concave portion 41, the convex portion and the bottom of the concave portion 41 are arranged against each other, and there is a gap between the top of the concave portion 41 and the seat portion 21. This makes it possible for the seat mechanism to change direction without friction due to the lack of contact between the top of the concave portion 41 and the seat portion 21, so that the force required to be applied to the seat body 2 is small, making the reversal operation of the seat mechanism less labor-saving.
[0066] Preferably, both first side walls 411 are inclined surfaces, and both second side walls 42 are also inclined surfaces. Thus, when the seat mechanism is reversed, the seat body 2 can rotate clockwise or counterclockwise relative to the support seat 1, making the reverse operation of the seat mechanism convenient.
[0067] The seat mechanism can be applied to a vehicle.
[0068] The carrier may be a child stroller, which includes a stroller frame, on which the support seat 1 is arranged. When the child stroller is in use, when the seat mechanism is in the first position, the child's back faces the adult pushing the child stroller. When the seat mechanism is in the second position, the child's face faces the adult pushing the child stroller.
[0069] The carrier may also be a child safety seat. When the seat mechanism is in the first position, the child's face faces the front of the car, and the child safety seat is used for older children. When the seat mechanism is in the second position, the child's face faces the rear of the car, and the child safety seat is used for younger infants.
[0070] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
