Description

Technical Field

[0001] This utility model relates to the field of child car safety seat technology, and in particular 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.

[0003] Therefore, there is an urgent need for a child safety seat to solve the above-mentioned technical problems. Utility Model Content

[0004] Based on the above, the purpose of this utility model is to provide a safety seat that eliminates the need for the operator to bend over and extend their body into the car, making it convenient to put the child in or take them out.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A safety seat includes a base frame, a rotating frame, and a rotation offset mechanism. The rotating frame has a seat mounting structure and is rotatably connected to the base frame via a rotating shaft. The rotation offset mechanism includes a swing member and a sliding groove. One end of the swing member is rotatably connected to the base frame, and the other end is rotatably connected to the rotating frame. The rotating shaft and the sliding groove are slidably engaged. The rotating shaft is located on one of the base frame and the rotating frame, and the sliding groove is located on the other. The position where the swing member is rotatably connected to the base frame is offset from the position of the rotating shaft, so that when the rotating frame rotates relative to the base frame, the rotating shaft can slide along the sliding groove under the action of the swing member.

[0007] In some possible implementations, the rotating frame is movable in a first position and a second position. When the rotating frame is in the first position, the orientation of the rotating frame is a first direction. When the rotating frame moves to the second position via the rotation offset mechanism, the central axis of the rotating frame deviates from the central axis of the rotating frame when it is in the first position, and the orientation of the rotating frame is a second direction different from the first direction, wherein the first direction is perpendicular to the second direction.

[0008] In some possible implementations, the rotating shaft is disposed on the rotating frame, the sliding groove is disposed on the base frame, and the swing member is rotatably connected to the rotating frame via a first shaft;

[0009] When the rotating frame rotates from the first position to the second position, the line connecting the first shaft and the rotating shaft is adjusted from extending in the front-back direction to extending in the left-right direction.

[0010] In some possible implementations, the other end of the swing member is pivotally connected to the base frame via a second shaft, and when the rotating frame is in the first position, the distance between the second shaft and the first shaft is approximately equal to the distance between the second shaft and the rotating shaft.

[0011] In some possible implementations, when the rotating frame is in the first position, the first shaft is located directly behind the rotating frame and is positioned relative to the rotating frame near the edge.

[0012] In some possible implementations, the first direction is forward or backward, and the second direction is left or right; the slide extends along the left-right direction and is disposed on the base frame.

[0013] In some possible implementations, the base frame is also provided with a clearance groove to allow the end of the swing member that is rotatably connected to the rotating frame to pass.

[0014] In some possible implementations, the rotation offset mechanism further includes a slider that is slidably disposed within the groove, and the rotating frame is rotatably connected to the slider via the rotation shaft.

[0015] In some possible implementations, the safety seat also has a travel limiting structure for limiting the rotation angle of the rotating frame; the travel limiting structure includes a first abutment portion disposed on the slider and a second abutment portion disposed on the rotating frame, wherein when the rotating frame moves to a second position, the second abutment portion abuts against the first abutment portion to limit further relative rotation between the rotating frame and the slider.

[0016] In some possible implementations, the slider is provided with an arc-shaped groove, the first abutting part is provided on the inner wall of the arc-shaped groove, and the second abutting part includes a guide post provided on the rotating frame. When the rotating frame rotates between the first position and the second position, the guide post slides along the arc-shaped groove.

[0017] In some possible implementations, the oscillating element includes a rocker arm, a linkage mechanism, or a connecting piece.

[0018] In some possible implementations, the rotating frame also has a third position symmetrically arranged with respect to the second position, wherein the orientation of the rotating frame when it is in the second position is opposite to the orientation of the rotating frame when it is in the third position.

[0019] In some possible implementations, the base frame includes a base and a support member, the support member being rotatably disposed within the base; the rotating frame is rotatably connected to the support member via the rotating shaft; one end of the swing member is rotatably connected to the support member, and the other end is rotatably connected to the rotating frame.

[0020] The beneficial effects of this utility model are as follows:

[0021] The safety seat provided by this utility model features a rotation offset mechanism that allows the rotating frame to shift to one side while rotating relative to the base frame. This causes the supporting body on the rotating frame to extend outward a certain distance relative to the base frame, making it easier for users to lift or remove children from the supporting body without bending over or reaching into the car. The rotation offset mechanism includes a swinging component and a sliding groove. The swinging component causes the rotating frame to shift laterally, resulting in a simple structure and reliable operation. The sliding groove guides the lateral shift of the rotating frame, ensuring stable movement of the rotating frame relative to the base frame and improving passenger comfort.

[0037] 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.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0041] Example 1

[0042] like Figures 1-10As shown, this embodiment provides a child safety seat, including a base frame 1, a rotating frame 2, and a rotation offset mechanism. The base frame 1 is configured to be mounted on a vehicle seat. The rotating frame 2 is rotatably connected to the base frame 1 via a rotating shaft 3; a seat mounting structure 21 is provided on the rotating frame 2 for mounting the support body. In this embodiment, the support body can specifically be a seat 100, suitable for older children, or a carrier 200, suitable for younger infants. The rotation offset mechanism includes a swing member 4 and a slide groove 5. One end of the swing member 4 is rotatably connected to the base frame 1, and the other end is rotatably connected to the rotating frame 2; the rotating shaft 3 and the slide groove 5 are slidably engaged. In this embodiment, the rotating shaft 3 can be located on the rotating frame 2, and the slide groove 5 can be located on the base frame 1; or the rotating shaft 3 can be located on the base frame 1, and the slide groove 5 can be located on the rotating frame 2, as long as the rotating shaft 3 can slide along the slide groove 5, thereby allowing the rotating frame 2 to move laterally relative to the base frame 1. In this embodiment, the position where the swing member 4 is rotatably connected to the base frame 1 should be offset from the position of the rotating shaft 3. That is, the position where the swing member 4 is rotatably connected to the base frame 1 cannot be located at the rotation center of the rotating frame 2. This is to avoid the swing member 4 and the rotating frame 2 rotating around the same center when the rotating frame 2 is rotated, thus preventing the lateral sliding of the rotating shaft 3. Therefore, in this embodiment, the position where the swing member 4 is rotatably connected to the base frame 1 is offset from the position of the rotating shaft 3, allowing the rotating frame 2 to rotate relative to the base frame 1, and the rotating shaft 3 to slide along the slide groove 5 through the action of the swing member 4.

[0043] The safety seat provided in this embodiment features a rotation offset mechanism. This mechanism allows the rotating frame 2 to shift to one side while rotating relative to the base frame 1. This causes the supporting structure on the rotating frame 2 to extend outwards relative to the base frame 1 by a certain distance, making it easier for users to lift or remove children from the supporting structure without bending over or reaching into the car. The rotation offset mechanism includes a swing element 4 and a sliding groove 5. The swing element 4 causes the rotating frame 2 to shift laterally, resulting in a simple structure and reliable operation. The sliding groove 5, in sliding engagement with the rotating shaft 3, guides the lateral shift of the rotating frame 2, ensuring the stability of the rotating frame 2's movement relative to the base frame 1 and improving the comfort of the passenger.

[0044] In this embodiment, the rotating frame 2 can move between a first position and a second position. When the rotating frame 2 is in the first position, its orientation is in the first direction. When the rotating frame 2 moves to the second position via the rotation offset mechanism, its central axis deviates from the central axis when it is in the first position, and its orientation is in the second direction, different from the first direction. Specifically, the first position is where the child normally sits in the car, while the second position is where the parent lifts or removes the child from the carrier after the rotating frame 2 extends to one side. In this embodiment, the first direction is perpendicular to the second direction. This arrangement allows the rotating frame 2 to extend to one side of the vehicle body during a 90-degree rotation, making it more convenient for the user to operate and ensuring that the extended carrier body faces the outside of the vehicle body. Furthermore, the first direction is forward or rearward, allowing the child to face forward or backward when sitting in the car seat, improving comfort and making it easier for parents to care for the child. The second direction is left or right, opposite the left or right door of the car. This allows the supporting body of the rotating frame 2 to be closer to the car door frame when it extends outward, and even partially extend beyond the door frame, making it easier for parents to place and secure the child to the supporting body. For example, during a 90-degree rotation to the left or right, the center of the rotating frame 2 shifts 170mm to the left or right, meaning the center of the supporting body shifts 170mm to the left or right, making it easier for users to lift the child into or out of the car seat. Correspondingly, the slide 5 in this embodiment extends in the left-right direction to allow the rotating frame 2 to smoothly shift to the left or right during rotation. For example, the slide 5 is located on the upper part of the base frame 1, and the rotating shaft 3 is located at the center of the rotating frame 2.

[0045] Furthermore, the rotating frame 2 also has a third position symmetrically arranged with respect to the second position, the orientation of the rotating frame 2 in the second position being opposite to that in the third position. Specifically, the second position can be a position where the rotating frame 2 extends to the left, and the third position can be a position where the rotating frame 2 extends to the right; when the rotating frame 2 is in the second position, the front of the supporting body faces the left side of the vehicle, and when the rotating frame 2 is in the third position, the front of the supporting body faces the right side of the vehicle. This arrangement allows the rotating frame 2 to shift to either the left or the right, allowing users to easily select and switch it to the second or third position depending on the installation position of the child safety seat in the car seat, while the supporting body faces the corresponding side door.

[0046] In this embodiment, the swing element 4 can be a swing rod, a linkage mechanism, or a connecting piece, as long as its two ends are rotatably connected to the base frame 1 and the rotating frame 2 respectively, and it can swing with the rotation of the rotating frame 2. For example, in this embodiment, the swing element 4 is a swing rod, which has a simple structure and is easy to install. Further, one end of the swing rod is pivotally connected to the rotating frame 2 via a first shaft 41, and the other end of the swing rod is pivotally connected to the base frame 1 via a second shaft 42. When the rotating frame 2 is in the first position, the line connecting the first shaft 41 and the rotating shaft 3 extends in the front-rear direction; when the rotating frame 2 is in the second position, the line connecting the first shaft 41 and the rotating shaft 3 extends in the left-right direction. This arrangement ensures that when the rotating frame 2 switches to the first or second position, the line connecting the first shaft 41 and the rotating shaft 3 is parallel to the longitudinal centerline of the rotating frame 2, resulting in a stable structure and reliable operation. Specifically, when the rotating frame 2 is in the first position, the first shaft 41 is located directly behind the rotating frame 2 and is positioned relatively close to the edge of the rotating frame 2. This makes it easier for the swing arm to move the rotating frame 2, resulting in smoother operation. Furthermore, when the rotating frame 2 is in the first position, the distance between the second shaft 42 and the first shaft 41 is approximately equal to the distance between the second shaft 42 and the rotating shaft 3. This ensures that the rotating frame 2 does not shift to one side during a 90-degree rotation, while also improving structural stability. Optionally, the base frame 1 is also provided with a clearance groove 121. During the rotation of the swing arm around the second shaft 42, the first shaft 41 can slide along the clearance groove 121. This reasonable structure ensures smooth rotation of the swing arm. Specifically, the clearance groove 121 is arc-shaped, with a radius equal to the length of the swing arm.

[0047] Optionally, the rotation offset mechanism further includes a slider 6, which is slidably disposed within the groove 5. The rotating frame 2 is rotatably connected to the slider 6 via a rotating shaft 3. By providing the slider 6, the connection between the rotating frame 2 and the base frame 1 is made more reliable, and the stability of the rotation and sliding of the rotating frame 2 is improved. Specifically, in this embodiment, the slider 6 is "H"-shaped, with its two sides slidably engaged with the groove 5, and a shaft hole 62 provided in the middle for connecting with the rotating shaft 3 on the rotating frame 2. Further, the safety seat also has a travel limiting structure for limiting the rotation angle of the rotating frame 2. This travel limiting structure includes a first abutment portion disposed on the slider 6 and a second abutment portion disposed on the rotating frame 2. When the rotating frame 2 moves to the second position, the second abutment portion abuts against the first abutment portion, thereby limiting the rotating frame 2 from continuing to rotate in the same direction. The above arrangement avoids further rotation of the rotating frame 2 after it rotates to the second position, allowing the rotating frame 2 to face the left or right side of the vehicle body at this time, making it convenient to lift children into and out of the safety seat, and improving the stability of the rotating frame 2 at this position. Optionally, in this embodiment, the sliding member 6 is provided with an arc-shaped groove 61. The first abutment portion is provided on the inner walls of both ends of the arc-shaped groove 61, and the second abutment portion includes a guide post 22 provided on the rotating frame 2. When the rotating frame 2 rotates between the first position and the second position, the guide post 22 slides along the arc-shaped groove 61. When the guide post 22 moves to the position abutting both ends of the arc-shaped groove 61, the rotating frame 2 can no longer rotate. Specifically, the arc-shaped groove 61 is arc-shaped, with the shaft hole 62 as the center and the distance between the rotating shaft 3 and the guide post 22 as the radius. This enables the rotating frame 2 to rotate smoothly relative to the sliding member 6, as well as to limit the rotation of the rotating frame 2.

[0048] Optionally, the base frame 1 in this embodiment includes a base 11 and a support member 12 disposed on the base 11. The base 11 is used for installation and fixation with the vehicle seat, and the support member 12 is used for connection with the rotating frame 2. Specifically, the rotating frame 2 is rotatably connected to the support member 12 via a rotating shaft 3. A sliding groove 5 is disposed on the upper part of the support member 12, and the rotating shaft 3 is slidably connected within the sliding groove 5. One end of the swing member 4 is rotatably connected to the support member 12, and the other end is rotatably connected to the rotating frame 2. Further, the support member 12 in this embodiment is disc-shaped and rotatably disposed within the base 11. The support member 12 can rotate 180° or 360° within the base 11 around a center line extending in the vertical direction, so that the load-bearing body can switch between a forward-facing orientation and a backward-facing orientation, and the placement angle of the load-bearing body can be flexibly adjusted. In addition, the safety seat can also be provided with a locking structure, which can lock the support member 12 after it has rotated to the desired angle.

[0049] Example 2

[0050] like Figures 1-2 ,and Figures 11-13As shown, this embodiment provides another type of child safety seat, which has a structure that is basically the same as that in Embodiment 1, except that:

[0051] The safety seat in this embodiment does not have a sliding member 6, a clearance groove 121, or a travel limit structure.

[0052] In this embodiment, one end of the rotating shaft 3 is mounted on the rotating frame 2, and the other end is rotatably mounted in the slide groove 5 and can slide along the slide groove 5. This arrangement simplifies the structure of the safety seat, makes installation easier, and helps reduce manufacturing costs. Of course, to improve the smoothness of the movement of the rotating shaft 3 in the slide groove 5, a slider can also be provided in the slide groove 5, with the lower end of the rotating shaft 3 rotatably connected to the slider, and the slider slidably connected to the slide groove 5.

[0053] This embodiment also enables the rotating frame 2 to shift to one side while rotating, thereby extending outward relative to the base frame 1. When placing a child on the supporting body, the user does not need to bend over or stick their body into the car to operate it, making it convenient to use and reducing bumps and collisions.

[0054] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
