Description

儿童安全座椅的旋转机构Child safety seat rotation mechanism

技术领域Technical field

本实用新型涉及一种汽车儿童安全座椅，尤其涉及一种可实现椅身相对椅座在水平方向上360度旋转的儿童安全座椅的旋转机构。The utility model relates to an automobile child safety seat, in particular to a rotation mechanism of a child safety seat which can realize a 360 degree rotation of a seat body relative to a seat in a horizontal direction.

背景技术Background technique

汽车儿童安全座椅，是一种专门为不同年龄段或体型的儿童设计的安全装置，安装在汽车内，能有效提高儿童乘车安全。在汽车发生碰撞或突然减速的情况下，可以减少对儿童的冲击力以及限制儿童的身体移动来减少对他们的危害。常见的汽车儿童安全座椅包The car child safety seat is a safety device specially designed for children of different ages or sizes. It is installed in the car and can effectively improve the safety of children. In the event of a collision or sudden deceleration of the car, the impact on the child can be reduced and the child's body movement can be limited to reduce the harm to them. Common car child safety seat bag

括椅座，椅身及设置于椅身上端的头靠。而目前市面上的大部分汽车儿童安全座椅在汽车The seat is seated, the chair body and the headrest disposed on the end of the chair. Most of the car child safety seats currently on the market are in the car.

上的安装方式为安全带固定方式，如中国专利CN103507677A所公开的安全带固定的汽车安全座椅结构，此安装方式的缺点主要是安装复杂，很多使用者特别是女性使用者不会安装或者是安装不到位，从而一定程度上造成了对儿童的危害的增加。作为改进，也有利用汽车上的ISOFIX接口固定的汽车儿童安全座椅，即在汽车儿童安全座椅上设计增加一组ISOFIX接口和top-tether，以对应连接在汽车上现有的ISOFIX接口，这样更有利于增加座椅装在汽车上的可靠性，而且安装也更简单方便。The installation method is the seat belt fixing method. For example, the seat belt fixed car seat structure disclosed in Chinese Patent CN103507677A, the disadvantage of this installation method is mainly that the installation is complicated, and many users, especially female users, will not install or The installation is not in place, which has caused an increase in the harm to children to some extent. As an improvement, there is also a car child safety seat fixed by the ISOFIX interface on the car, that is, a set of ISOFIX interface and top-tether is designed on the car child safety seat to correspond to the existing ISOFIX interface connected to the car, so that It is more conducive to increasing the reliability of the seat on the car, and the installation is also simpler and more convenient.

为提高儿童安全座椅乘坐的舒适性，有很多安全座椅的椅身可相对椅座进行倾斜角度(俯仰角度)的调节，如授权公告号为CN204605578U的中国实用新型专利《一种汽车儿童安全座椅》就披露这样一种椅身可相对椅座进行倾斜角度调节的安全座椅。In order to improve the comfort of the child safety seat, the seat body of many safety seats can be adjusted with respect to the tilt angle (pitch angle) of the seat, such as the Chinese utility model patent CN204605578U, a car child safety. The Seat discloses a safety seat in which the seat body can be tilted relative to the seat.

随着人们对儿童安全乘车意识的进一步提高，在小孩较小的时候，儿童安全座椅适合反装进而使小孩躺倒，而小孩较大了以后，儿童安全座椅需要正装。所以如果要在正装和反装之间切换的话，一般需要将安全座椅整个拆卸下来重新安装，也非常不便。儿童尤其是婴儿其年龄较小，不能自己解除安全座椅上的安全带，就算能解除，因安全座椅整体高度较高，儿童上下车也很不方便，故一般需要家长辅助，上车时，大人怀抱儿童上车后，大人扭转身躯将儿童置于座椅上，接着进行安全带扣结，下车时，同样大人扭转身躯接触安全带，再将儿童从安全座椅上抱下，因车内空间较小，这种扭动身躯在车内操作并怀抱小孩非常不方便，尤其是儿童体重较重情况下，大人更显疲累。With the further improvement of children's awareness of safe riding, when the child is small, the child safety seat is suitable for reversing and then the child is lying down. After the child is larger, the child safety seat needs formal dressing. Therefore, if you want to switch between dressing and reverse loading, it is generally inconvenient to remove the safety seat and reinstall it. Children, especially babies, are younger and cannot lift the seat belts on the safety seat themselves. Even if they can be lifted, because the overall height of the safety seat is high, it is very inconvenient for children to get on and off. Therefore, parents are generally required to assist. After the adult embraces the child in the car, the adult turns the body to place the child on the seat, and then the seat belt buckles. When the vehicle is disembarked, the same person turns the body to touch the seat belt, and then the child is hung from the safety seat. The space inside the car is small. It is very inconvenient to operate the body and hold the child in the car. Especially when the child is heavier, the adult is more tired.

如何设计出一款方便大人在车外便可将儿童置于安全座椅上的儿童安全座椅是本领域技术人员需要考虑的技术问题。How to design a child safety seat that allows a child to be placed on a safety seat outside the vehicle is a technical problem to be considered by those skilled in the art.

In the state, the adjustment handle forces the lock lever to be in the upper portion of the inclined hole, that is, the lock lever has a tendency to always snap into the lock tooth. The structure is also convenient for adjusting the tilt angle of the chair body. When adjusting, the handle is pulled outward, forcing the lock lever to move downward relative to the inclined hole. When the lock lever is located at the lower part of the inclined hole, the lock lever is disengaged from the lock tooth to release the limit of the seat body. The chair body can be pushed back and forth, and the chair body swings back and forth in a certain arc. When the adjustment is in place, the handle is relaxed, and the handle is moved forward by the tension spring, forcing the lock lever to move up relative to the inclined hole, when the lock lever is located at the upper part of the inclined hole The locking rod is snapped into the locking tooth, and the seat body is positioned relative to the seat by the action of the fixing rod and the locking rod.

为使椅身相对椅座在前后方向上的移动更为平稳，上述第一锁板的上部开有沿其长度方向延伸设置的弧形槽，所述第二锁板的上部开有第二定位孔，有导向杆其两端穿过第二定位孔后***弧形槽内，导向杆能沿弧形槽滑移。In order to make the movement of the seat body relative to the seat in the front-rear direction more stable, the upper portion of the first lock plate is provided with an arcuate groove extending along the longitudinal direction thereof, and the upper portion of the second lock plate is provided with the second position. The hole has a guiding rod which is inserted into the arc groove through the second positioning hole, and the guiding rod can slide along the arc groove.

本旋转机构的工作原理及过程如下：The working principle and process of this rotating mechanism are as follows:

换位调节过程：只需外拉滑板把手5，带动卡块51脱离卡槽32，便可转动椅身2，然后放松滑动把手5，当椅身2转动到下个角度位置时，滑动把手5在弹簧52压力作用下带动卡块51内移，***卡槽32内，实现对转盘3的周向定位，转盘3及椅身2就不能相对椅座1进行360度旋转了。The transposition adjustment process: only the outer slider handle 5 is pulled out, and the card block 51 is disengaged from the card slot 32, the chair body 2 can be rotated, and then the sliding handle 5 is released. When the chair body 2 is rotated to the next angular position, the sliding handle 5 is swung. Under the action of the spring 52, the slider 51 is moved inwardly and inserted into the card slot 32 to realize the circumferential positioning of the turntable 3. The turntable 3 and the body 2 cannot be rotated 360 degrees with respect to the seat 1.

倾斜角度调节过程：调节时将调节拉手8外拉，迫使锁定杆9b相对斜孔83下移，当锁定杆9b位于斜孔83下部时，锁定杆9b脱离锁齿72解除对椅身2的限位，便可前后推拉椅身2，椅身2以一定弧度相对椅座1前后摆动，当调节到位后，放松调节拉手8，调节拉手8在拉簧84作用下前移，迫使锁定杆9b相对斜孔83上移，当锁定杆9b位于斜孔83上部时，锁定杆9b卡入锁齿72，通过固定杆9a和锁定杆9b的作用，将椅身2相对椅座1定位。Tilt angle adjustment process: when adjusting, the adjustment handle 8 is pulled out, forcing the lock lever 9b to move downward relative to the inclined hole 83. When the lock lever 9b is located at the lower part of the inclined hole 83, the lock lever 9b is disengaged from the lock tooth 72 to release the limit of the seat body 2. The seat body 2 can be pushed and pulled back and forth, and the chair body 2 swings back and forth with respect to the seat 1 with a certain curvature. When the adjustment is in place, the adjustment handle 8 is relaxed, and the adjustment handle 8 is moved forward by the tension spring 84, forcing the lock lever 9b to be opposite. The inclined hole 83 is moved upward, and when the lock lever 9b is located at the upper portion of the inclined hole 83, the lock lever 9b is engaged with the lock tooth 72, and the seat body 2 is positioned relative to the seat 1 by the action of the fixed lever 9a and the lock lever 9b.
