Automobile child safety seats play an important role in reducing child casualties in collision accidents.
ISOFIX为现有常用的儿童安全座椅固定方式，通过ISOFIX可快速的安装及拆卸儿童座椅，且可靠性高。因市面上车型繁多，ISOFIX需做到长度可调才能尽可能适配更多车型，因此ISOFIX一般会置于一套滑轨机构中。而滑轨的存在导致结构悬臂增长，所以对整套机构强度提出更高要求，其次，考虑到安全性，两侧的ISOFIX之间的间距应当达到规范要求，导致座椅底座尺寸较宽，不利于轻量化生产需求。ISOFIX is a commonly used method for fixing child safety seats. Through ISOFIX, child seats can be quickly installed and removed with high reliability. Due to the large number of models on the market, ISOFIX needs to be adjustable in length to fit as many models as possible, so ISOFIX is generally placed in a set of slide rail mechanisms. The presence of the slide rails results in the growth of the structural cantilever, so higher requirements are placed on the strength of the entire mechanism. Secondly, considering the safety, the spacing between the ISOFIX on both sides should meet the specification requirements, resulting in a wider seat base size, which is not conducive to Lightweight production needs.

底座骨架11具有一底板111和设于底板111两侧的二侧板112，在本实施例中，为节省材料，底板111前后宽度尺寸较小，仅仅位于座椅前部位置，而不是整面布置。两侧的二侧板112则通长设置，长度匹配于整个儿童安全座椅底座的长度，二侧板112的前部焊接或一体成型于底板111的左右两侧，构成了本发明实施例中的底座骨架11。The base frame 11 has a bottom plate 111 and two side plates 112 provided on both sides of the bottom plate 111. In this embodiment, in order to save material, the width of the front and back of the bottom plate 111 is small, and it is only located at the front of the seat instead of the entire surface Layout. The two side plates 112 on both sides are set long, and the length matches the length of the entire child safety seat base. The front of the two side plates 112 is welded or integrally formed on the left and right sides of the bottom plate 111, which constitutes an embodiment of the present invention的 基基 11。 The base skeleton 11.
两侧的侧板112上分别设有一滑轨10，滑轨10为长条形滑轨，沿着侧板112的长度方向设置。并且，滑轨10贯穿所在侧板112的两侧而在侧板112上构成开孔构造。为加强开孔后的侧板112的强度，在每一滑轨10的四周设置了滑轨加强板100，滑轨加强板100亦采用高强钢或其他高强材料制成，滑轨加强板100采用焊接或螺栓连接于侧板112的内侧并与侧板112紧密贴合，优选地，滑轨加强板100采用形状和尺寸匹配于侧板112中开设滑轨10的侧板区段，即本实施例中侧板112的后半段区段，且滑轨加强板100上设有形状和尺寸匹配于滑轨10的开孔，避免滑轨加强板100遮盖滑轨10。A slide rail 10 is respectively provided on the side plates 112 on both sides, and the slide rail 10 is a long slide rail and is arranged along the length direction of the side plate 112. In addition, the slide rail 10 penetrates both sides of the side plate 112 to form an opening structure in the side plate 112. In order to enhance the strength of the side plate 112 after the opening, a slide rail reinforcement plate 100 is provided around each slide rail 10. The slide rail reinforcement plate 100 is also made of high-strength steel or other high-strength materials. It is welded or bolted to the inner side of the side plate 112 and closely adheres to the side plate 112. Preferably, the slide rail reinforcement plate 100 adopts a shape and size matching the side plate section in which the slide rail 10 is opened in the side plate 112, which is In the example, the rear half section of the side plate 112 is provided with an opening that matches the shape and size of the slide rail 10 to prevent the slide rail reinforcement plate 100 from covering the slide rail 10.
另外，还可以采用在底座骨架11的两侧板112之间加设横梁113来提高底座骨架11的整体强度，克服因侧板开设滑轨后导致结构悬臂增长而有损儿童安全座椅底座整体强度的弊端，优选地，横梁113连接在两侧侧板112的后端之间。In addition, cross beams 113 can be added between the two side plates 112 of the base frame 11 to improve the overall strength of the base frame 11 to overcome the structural cantilever growth caused by the side plates opening the slide rails and damaging the overall base of the child safety seat The disadvantage of strength is that the beam 113 is preferably connected between the rear ends of the side plates 112 on both sides.
ISOFIX支架12位于底座骨架11的两侧侧板112之间，如图3所示，ISOFIX支架12由一主体板件121和设于该主体板件121的两侧的二连接板件122构成，其中，主体板件121的形状呈飞机尾翼的形状，两侧较宽、中部较窄，二连接板122焊接或一体成型于主体板件121的两侧，连接板件122与主体板件121之间呈90度夹角连接，连接板件122向下翻折，连接板件122用于连接滑动连接件13，ISOFIX支架12两侧的二连接板122上均连接有滑动连接件13。滑动连接件13滑设于对应侧的底座骨架11上的滑轨10中，并 且，滑动连接件13的外侧头部伸出至滑轨10所在侧板112的外侧，即滑动连接件13的外侧头部露出于滑轨10。The ISOFIX bracket 12 is located between the side plates 112 on both sides of the base frame 11. As shown in FIG. 3, the ISOFIX bracket 12 is composed of a main body plate 121 and two connecting plates 122 provided on both sides of the main body plate 121. Among them, the shape of the main body plate 121 is the shape of an aircraft tail, the sides are wider and the middle is narrower, the two connecting plates 122 are welded or integrally formed on both sides of the main body plate 121, the connecting plate 122 and the main body plate 121 The connection is made at an angle of 90 degrees. The connection plate 122 is folded downward. The connection plate 122 is used to connect the sliding connection 13. The two connection plates 122 on both sides of the ISOFIX bracket 12 are connected to the sliding connection 13. The sliding connector 13 is slidably disposed in the sliding rail 10 on the base frame 11 on the corresponding side, and the outer head of the sliding connector 13 extends to the outside of the side plate 112 where the sliding rail 10 is located, that is, the outer side of the sliding connector 13 The head is exposed to the slide rail 10.
ISOFIX连接件14用于连接汽车座椅上的ISOFIX接口，从而将儿童安全座椅固定连接在汽车座椅上。二ISOFIX连接件14一一对应地位于两侧侧板112的外侧，且ISOFIX连接件14连接于所在侧侧板112处的滑动连接件13的外露的头部。随滑动连接件13于滑轨10中的滑动，ISOFIX连接件14可同步沿着滑轨10滑动，实现伸缩。The ISOFIX connector 14 is used to connect the ISOFIX interface on the car seat, so that the child safety seat is fixedly connected to the car seat. The two ISOFIX connectors 14 are located on the outside of the side plates 112 on both sides, and the ISOFIX connectors 14 are connected to the exposed heads of the sliding connectors 13 at the side plates 112. As the sliding connecting member 13 slides in the sliding rail 10, the ISOFIX connecting member 14 can simultaneously slide along the sliding rail 10 to achieve telescoping.
优选地，在ISOFIX连接件的末端设置一加强连接件141，加强连接件141可采用高强钢或其他高强材料制成，加强连接件141与ISOFIX连接件14通过螺栓或焊接连接成一体，令加强连接件作为ISOFIX连接件的一部分，加强连接件141连接于滑动连接件，ISOFIX连接件通过该加强连接件141连接于滑动连接件。Preferably, a reinforced connecting piece 141 is provided at the end of the ISOFIX connecting piece.

The ISOFIX connecting piece is connected to the sliding connecting piece through the reinforcing connecting piece 141.
较佳地，ISOFIX支架12的每一侧上的滑动连接件13的数量不少于两个，通过设置多个滑动连接件13共同滑设于滑轨中，可以提高滑动时的平稳性，另外，当发生碰撞事故时，座椅整体的大部分受力将作用在ISOFIX连接件上，其中有一大部分分力为使座椅旋转/翻转的力，而座椅一旦翻转程度较大，那么儿童乘员的头部易与车内座椅等发生碰撞，对儿童造成伤害，所以，ISOFIX连接件与儿童安全座椅底座之间应尽量保证无翻转。因此，在本发明实施例中采用增加滑动连接件的做法，保证ISOFIX连接件和ISOFIX支架相对于滑轨的滑动是平稳的，同时，整套ISOFIX结构(包含ISOFIX连接件和ISOFIX支架)能承受较大的翻转力，保护儿童乘员的安全。除了本实施例中所使用的上述增加滑动连接件13的方式之外，还可以采用截面为矩形或圆角矩形等与滑轨间有多个接触点甚至接触面的异形螺栓或受力件作为滑动连接件，从而达到增加滑动连接件与滑轨之间的接触，将原本单个滑动连接件与滑轨之间仅两点接触的形式转变为具有多个接触点设置接触面的形式，从而提高整套ISOFIX结构与滑轨之间的支点个数或面积，提升整套ISOFIX结构的滑动平稳性和抗翻转能力。Preferably, the number of the sliding connectors 13 on each side of the ISOFIX bracket 12 is not less than two. By providing a plurality of sliding connectors 13 to slide together in the sliding rail, the stability during sliding can be improved, in addition In the event of a collision, most of the force of the seat will act on the ISOFIX connector. A large part of the component force is the force to rotate / turn the seat. Once the seat is turned over, the child The head of the occupant is likely to collide with the seats in the car and cause injury to children. Therefore, there should be no flipping between the ISOFIX connector and the base of the child safety seat. Therefore, in the embodiment of the present invention, the method of adding a sliding connector is adopted to ensure that the sliding of the ISOFIX connector and the ISOFIX bracket relative to the slide rail is stable, and at the same time, the entire ISOFIX structure (including the ISOFIX connector and the ISOFIX bracket) can withstand relatively The large turning force protects the safety of the child occupants. In addition to the above-mentioned way of adding the sliding connector 13 used in this embodiment, a special-shaped bolt or a stress member having a rectangular cross section or a rounded rectangle with multiple contact points or even contact surfaces with the slide rail can also be used Sliding connector, so as to increase the contact between the sliding connector and the slide rail, transforming the original two-point contact between the single sliding connector and the slide rail into a form with multiple contact points to set the contact surface, thereby improving The number or area of fulcrums between the entire ISOFIX structure and the slide rails improves the sliding stability and anti-overturning ability of the entire ISOFIX structure.
较佳地，在滑动连接件13的外侧套设有减震垫圈130，减震垫圈130可采用塑料垫圈，套设在滑动连接件中位于滑轨中的光杆部分，塑料垫圈与滑轨接触，可起到增加润滑及减小噪音的功能。Preferably, a shock-absorbing washer 130 is sleeved on the outer side of the sliding connector 13.
