具体实施方式Detailed ways

下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

下面参考附图描述根据本发明实施例的儿童安全座椅100。A child safety seat 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

根据本发明实施例的儿童安全座椅100,如图1所示,包括:座椅本体1、头枕2和底座3。A child safety seat 100 according to an embodiment of the present invention, as shown in FIG. 1 , includes: a seat body 1 , a headrest 2 and a base 3 .

具体地,座椅本体1包括椅座11和椅背12,可以理解的是,儿童安全座椅100使用时,儿童坐在椅座11上且背靠在椅背12上,椅背12具有内侧面S1和外侧面S2,椅背12的被倚靠的表面为椅背12的内侧面S1,椅背12的与内侧面S1相对的表面则为椅背12的外侧面S2。Specifically, the seat body 1 includes a seat 11 and a seat back 12. It can be understood that when the child safety seat 100 is in use, the child sits on the seat 11 and leans against the seat back 12, and the seat back 12 has an inner The side S1 and the outer side S2 , the leaning surface of the seat back 12 is the inner side S1 of the seat back 12 , and the surface of the seat back 12 opposite to the inner side S1 is the outer side S2 of the seat back 12 .

参照图1-图3,头枕2设在椅背12的内侧面S1上,儿童安全座椅100还包括用于调整头枕2在椅背12上高度的高度调整机构4。Referring to FIGS. 1-3 , the headrest 2 is arranged on the inner side S1 of the seat back 12 , and the child safety seat 100 also includes a height adjustment mechanism 4 for adjusting the height of the headrest 2 on the seat back 12 .

具体地,如图3所示,椅背12上设有在厚度方向贯通的导向槽13,椅背12的外侧面S2在导向槽13的水平两侧分别形成滑行面,每个滑行面上设有沿竖向排布的多个卡槽14。Specifically, as shown in FIG. 3 , the seat back 12 is provided with a guide groove 13 penetrating in the thickness direction, and the outer surface S2 of the seat back 12 forms sliding surfaces on both horizontal sides of the guide groove 13, and each sliding surface is provided with There are a plurality of card slots 14 arranged vertically.

如图2-图4所示,高度调整机构4包括:操作部41、固定部42和调节部43,操作部41与头枕2相连,操作部41在朝向椅背12的外侧面S2一侧设有滑槽411,滑槽411的上表面F1和下表面F2在朝向椅背12的外侧面S2的方向上远离彼此延伸。固定部42包括滑板422和导向块421,导向块421设在滑板422的朝向头枕2的一侧且与头枕2相连,导向块421插入至导向槽13内且可沿导向槽13上下滑动,滑板422可沿导向槽13两侧的滑行面滑动。该实施例中滑板422的设置可使固定部42与座椅本体1的椅背12接触面积大、滑行平稳,但是本发明实施例中固定部42的结构可不限于此,在其他实施例中,固定部42也可仅设置有沿导向槽13上下滑动的导向块421,这就相当于固定部42上去掉了滑板422的结构。As shown in FIGS. 2-4 , the height adjustment mechanism 4 includes: an operating part 41 , a fixing part 42 and an adjusting part 43 , the operating part 41 is connected to the headrest 2 , and the operating part 41 is on the side facing the outer surface S2 of the seat back 12 A sliding groove 411 is provided, and the upper surface F1 and the lower surface F2 of the sliding groove 411 extend away from each other in a direction toward the outer surface S2 of the seat back 12 . The fixed part 42 includes a slide plate 422 and a guide block 421. The guide block 421 is arranged on the side of the slide plate 422 facing the headrest 2 and connected with the headrest 2. The guide block 421 is inserted into the guide groove 13 and can slide up and down along the guide groove 13. , the sliding plate 422 can slide along the sliding surfaces on both sides of the guide groove 13 . The arrangement of the sliding plate 422 in this embodiment can make the contact area between the fixing part 42 and the seat back 12 of the seat body 1 large and slide smoothly, but the structure of the fixing part 42 in the embodiment of the present invention is not limited thereto. In other embodiments, The fixed part 42 can also only be provided with a guide block 421 that slides up and down along the guide groove 13 , which is equivalent to a structure in which the sliding plate 422 is removed from the fixed part 42 .

调节部43可移动地设在固定部42上,调节部43包括:卡杆431、凸柱432和弹性件433,卡杆431卡合在导向槽13两侧的卡槽14内,凸柱432穿过导向槽13插入至滑槽411内,弹性件433用于常驱动凸柱432朝向头枕2移动。这里,“常”指的是常态,“常驱动”表示弹性件433对凸柱432具有一个经常朝向某个方向推动的趋势。The adjustment part 43 is movably arranged on the fixed part 42. The adjustment part 43 includes: a clamping rod 431, a convex post 432 and an elastic member 433. Inserted into the slide groove 411 through the guide groove 13 , the elastic member 433 is used to constantly drive the protrusion 432 to move toward the headrest 2 . Here, "normal" refers to a normal state, and "constant driving" means that the elastic member 433 has a tendency to push the protruding post 432 in a certain direction.

具体而言,高度调整机构4中操作部41与固定部42均与头枕2相连,其中的操作部41甚至可一体形成在头枕2上,当将头枕2、操作部41和固定部42中的一个上下拉动时,其余两个可随之上下滑动。Specifically, the operating part 41 and the fixing part 42 of the height adjustment mechanism 4 are connected to the headrest 2, and the operating part 41 can even be integrally formed on the headrest 2. When the headrest 2, the operating part 41 and the fixing part When one of the 42 is pulled up and down, the other two can slide up and down thereupon.

这里,由于固定部42包括滑板422和导向块421,导向块421与头枕2相连,滑板422沿导向槽13两侧的滑行面滑动,从而导向块421连接在头枕2和滑板422之间,头枕2和滑板422夹设在椅背12的两侧。由于固定部42中导向块421配合在椅背12上的导向槽13内,因此当头枕2高度调整时,头枕2、操作部41及固定部42均沿导向槽13的延伸方向滑动。Here, since the fixed part 42 includes a slide plate 422 and a guide block 421, the guide block 421 is connected with the headrest 2, and the slide plate 422 slides along the sliding surfaces on both sides of the guide groove 13, so that the guide block 421 is connected between the headrest 2 and the slide plate 422 , the headrest 2 and the slide plate 422 are clamped on both sides of the seat back 12 . Since the guide block 421 in the fixing part 42 fits in the guide groove 13 on the seat back 12, when the height of the headrest 2 is adjusted, the headrest 2, the operating part 41 and the fixing part 42 all slide along the extending direction of the guide groove 13.

由于调节部43中,卡杆431卡合在导向槽13两侧的卡槽14内,凸柱432穿过导向槽13插入至滑槽411内,弹性件433用于常驱动凸柱432朝向头枕2移动,因此高度调整机构4具有两种状态,一种为高度稳定状态,另一种为高度调节状态。Because in the adjustment part 43, the clamping rod 431 is engaged in the clamping groove 14 on both sides of the guide groove 13, the protruding post 432 is inserted into the sliding groove 411 through the guiding groove 13, and the elastic member 433 is used to constantly drive the protruding post 432 toward the head. The pillow 2 moves, so the height adjustment mechanism 4 has two states, one is a height stable state, and the other is a height adjustment state.

在头枕2高度稳定状态下,弹性件433将凸柱432紧紧地扣在滑槽411内,凸柱432被压紧(或拉紧)在滑槽411内后,卡杆431的两端可分别紧紧地卡合在导向槽13两侧的卡槽14内,从而头枕2不能上下滑动。When the height of the headrest 2 is stable, the elastic member 433 tightly buckles the protruding column 432 in the chute 411, and after the protruding column 432 is compressed (or tensioned) in the chute 411, the two ends of the locking rod 431 They can be tightly engaged in the card slots 14 on both sides of the guide slot 13, so that the headrest 2 cannot slide up and down.

当向上拉动头枕2(或者操作部41)时,操作部41会相对调节部43的凸柱432向上移动,使得调节部43的凸柱432止抵在滑槽411的下表面F2上。在操作部41向上移动的过程中,凸柱432克服了弹性件433的弹性力而被滑槽411的下表面F2向外顶出。在凸柱432向外顶出的同时,调节部43的卡杆431也随之向卡槽14外顶出。没有卡杆431的卡止作用后,固定部42可随头枕2沿滑行面向上滑动。直到停止向上拉动头枕2(或者操作部41)后,凸柱432再次被弹性件433压紧(或拉紧)在滑槽411内,卡杆431的两端也分别紧紧地卡合在卡槽14内,从而头枕2不能再向上调节。When the headrest 2 (or the operation part 41 ) is pulled upward, the operation part 41 will move upward relative to the protrusion 432 of the adjustment part 43 , so that the protrusion 432 of the adjustment part 43 stops against the lower surface F2 of the slide groove 411 . During the upward movement of the operation part 41 , the protrusion 432 overcomes the elastic force of the elastic member 433 and is pushed outward by the lower surface F2 of the slide groove 411 . When the protrusion 432 is pushed out, the locking rod 431 of the adjustment part 43 is also pushed out of the locking slot 14 . Without the locking effect of the locking rod 431 , the fixing part 42 can slide upward along the sliding surface along with the headrest 2 . After stopping to pull the headrest 2 (or the operating part 41) upwards, the boss 432 is compressed (or tensioned) in the slide groove 411 by the elastic member 433 again, and the two ends of the locking rod 431 are also tightly engaged in the sliding groove 411. In the card slot 14, the headrest 2 can no longer be adjusted upwards.

同样,当向下按动头枕2(或者操作部41)时,操作部41会相对调节部43的凸柱432向下移动,使得调节部43的凸柱432止抵在滑槽411的上表面F1上。在操作部41向下移动的过程中,凸柱432克服了弹性件433的弹性力而被滑槽411的上表面F1向外顶出。在凸柱432向外顶出的同时,调节部43的卡杆431也随之向卡槽14外顶出,固定部42可随头枕2沿滑行面向下滑动。直到停止向下按动头枕2(或者操作部41)后,凸柱432再次被弹性件433压紧(或拉紧)在滑槽411内,卡杆431的两端也分别紧紧地卡合在卡槽14内,从而头枕2不能再向下调节。Similarly, when the headrest 2 (or the operating part 41 ) is pushed down, the operating part 41 will move downwards relative to the protrusion 432 of the adjustment part 43 , so that the protrusion 432 of the adjustment part 43 stops against the top of the slide groove 411 on the surface F1. During the downward movement of the operating part 41 , the protrusion 432 overcomes the elastic force of the elastic member 433 and is pushed outward by the upper surface F1 of the slide groove 411 . When the protrusion 432 is pushed out, the locking rod 431 of the adjustment part 43 is also pushed out of the locking groove 14 , and the fixing part 42 can slide down along the sliding surface along with the headrest 2 . After the headrest 2 (or the operating part 41 ) is stopped, the boss 432 is compressed (or tensioned) in the chute 411 by the elastic member 433 again, and the two ends of the clamping rod 431 are also tightly clamped respectively. Closed in the card slot 14, so that the headrest 2 can no longer be adjusted downwards.

在一些实施例中,如图2和图3所示,操作部41固定连接在头枕2的背面,操作部41形成为长条直板状,操作部41的顶端设有拉手412,滑槽411形成在操作部41的底端。这样当调整头枕2高度时,可直接上下拉动拉手412,操作更加容易。In some embodiments, as shown in Fig. 2 and Fig. 3, the operating part 41 is fixedly connected to the back of the headrest 2, and the operating part 41 is formed in the shape of a long straight plate. Formed at the bottom end of the operation portion 41 . In this way, when the height of the headrest 2 is adjusted, the handle 412 can be directly pulled up and down, making the operation easier.

具体地,如图3所示,当椅背12上设有多个导向槽13时,操作部41可对应每个导向槽13设置滑槽411,同时调节部43可对应多个滑槽411设置多个凸柱432和多个弹性件433。这样可保证在调整头枕2高度时,头枕2在水平方向上受力均匀,运动平稳。Specifically, as shown in Figure 3, when the seat back 12 is provided with a plurality of guide grooves 13, the operating part 41 can be provided with a slide groove 411 corresponding to each guide groove 13, and the adjustment part 43 can be provided corresponding to a plurality of slide grooves 411. A plurality of protrusions 432 and a plurality of elastic members 433 . This can ensure that when the height of the headrest 2 is adjusted, the headrest 2 is evenly stressed in the horizontal direction and moves smoothly.

在图4所示的实施例中,操作部41底部可设有两个滑槽411,具体地,操作部41底部形成有方形块,方形块的左右两侧面上形成有滑槽411,左侧的滑槽411在左侧是敞开的,右侧的滑槽411在右侧是敞开的。In the embodiment shown in Fig. 4, two sliding grooves 411 may be provided at the bottom of the operating part 41. Specifically, a square block is formed at the bottom of the operating part 41, and sliding grooves 411 are formed on the left and right sides of the square block. The chute 411 on the left side is open, and the chute 411 on the right side is open on the right side.

进一步地,如图3所示,头枕2在朝向椅背12的一侧设有固定槽21,操作部41设在固定槽21内。这样头枕2滑动时,操作部41不会产生干涉妨碍。Further, as shown in FIG. 3 , the headrest 2 is provided with a fixing groove 21 on the side facing the seat back 12 , and the operating part 41 is arranged in the fixing groove 21 . In this way, when the headrest 2 slides, the operation part 41 does not interfere.

具体地,如图2和图3所示,高度调整机构4还包括滑盖44,滑盖44盖合在固定槽21上,滑盖44位于操作部41和椅背12之间。由图3可以看出,滑盖44的朝向椅背12的表面是平滑面,滑盖44的设置可减小头枕2调整时操作部41与椅背12之间的摩擦力,使头枕2的高度调整更加省力。Specifically, as shown in FIG. 2 and FIG. 3 , the height adjustment mechanism 4 further includes a sliding cover 44 that covers the fixing groove 21 and is located between the operating portion 41 and the seat back 12 . As can be seen from Fig. 3, the surface of the slide cover 44 facing the seat back 12 is a smooth surface, and the setting of the slide cover 44 can reduce the friction between the operation part 41 and the seat back 12 when the headrest 2 is adjusted, so that the headrest 2 The height adjustment is more labor-saving.

在一些实施例中,如图2-图4所示,调节部43包括:卡杆431、凸柱432、弹性件433和滚轮434。凸柱432可为一个或者多个,每个凸柱432上配置有弹性件433和滚轮434。In some embodiments, as shown in FIGS. 2-4 , the adjusting part 43 includes: a locking rod 431 , a boss 432 , an elastic member 433 and a roller 434 . There can be one or more protrusions 432 , and each protrusion 432 is provided with an elastic member 433 and a roller 434 .

其中,卡杆431可为长直的圆杆,而座椅本体1上所有卡槽14的竖向截面均为半圆形,有利地,卡杆431的半径与卡槽14的竖向截面的半径大体相等,这样卡杆431滑入或者滑出卡槽14时均较平缓,可避免卡杆431卡死的现象。Wherein, the clamping rod 431 can be a long straight round rod, and the vertical sections of all the clamping grooves 14 on the seat body 1 are semicircular. The radii are substantially equal, so that when the clamping rod 431 slides into or slides out of the clamping slot 14, it is relatively gentle, which can avoid the phenomenon that the clamping rod 431 is stuck.

具体地,如图4所示,凸柱432的远离头枕2的一端形成轴套435,轴套435可拆卸地外套在卡杆431上,这样可方便调节部43的装配。Specifically, as shown in FIG. 4 , an end of the boss 432 away from the headrest 2 forms a bushing 435 , and the bushing 435 is detachably covered on the clamping rod 431 , which facilitates the assembly of the adjusting part 43 .

更具体地,如图4所示,凸柱432的另一端设有滚轮434,即滚轮434设在凸柱432的伸入至滑槽411的端部,这样当上下调节头枕2时,滚轮434可沿滑槽411的下表面F2或者上表面F1滑动,滚轮434的设置可将凸柱432与滑槽411表面之间的滑动摩擦转化为滚动摩擦,从而可使头枕2的高度调节更加顺畅省力。More specifically, as shown in FIG. 4 , the other end of the boss 432 is provided with a roller 434 , that is, the roller 434 is located at the end of the boss 432 extending into the chute 411 , so that when the headrest 2 is adjusted up and down, the roller 434 434 can slide along the lower surface F2 or the upper surface F1 of the chute 411, and the setting of the roller 434 can convert the sliding friction between the boss 432 and the surface of the chute 411 into rolling friction, so that the height adjustment of the headrest 2 can be more easily adjusted. Smooth and effortless.

在一些具体实施例中,如图4和图2所示,导向块421上设有贯通的导向孔423,凸柱432可伸缩地设在导向孔423内。这样可限制调节部43在固定部42上的活动范围,保证头枕2在上下活动时,调节部43的凸柱432沿导向孔423的延伸方向伸缩,从而可提高头枕2调节的结构可靠性。In some specific embodiments, as shown in FIG. 4 and FIG. 2 , the guide block 421 is provided with a through guide hole 423 , and the protrusion 432 is telescopically arranged in the guide hole 423 . This can limit the range of motion of the adjusting part 43 on the fixing part 42, and ensure that when the headrest 2 moves up and down, the protruding post 432 of the adjusting part 43 expands and contracts along the extension direction of the guide hole 423, thereby improving the structural reliability of the adjustment of the headrest 2. sex.

具体地,弹性件433为弹簧,弹簧设在导向孔423内且外套在凸柱432上,弹簧的一端抵接在导向块421上且另一端抵接在凸柱432上。用弹簧外套在凸柱432上且用弹簧来驱动凸柱432活动,一方面可保证弹性件433不从凸柱432上脱落,另一方面也是可保证弹性件433的弹性力大而稳定,从而保证调节部43的结构可靠性高。Specifically, the elastic member 433 is a spring. The spring is disposed in the guide hole 423 and covers the boss 432 . One end of the spring abuts on the guide block 421 and the other end of the spring abuts on the boss 432 . Cover the boss 432 with a spring and use the spring to drive the boss 432 to move. On the one hand, it can ensure that the elastic member 433 does not fall off from the boss 432. On the other hand, it can also ensure that the elastic force of the elastic member 433 is large and stable, so that It is ensured that the structural reliability of the adjusting part 43 is high.

更具体地,如图4和图3所示,固定部42上每个导向块421的上端均超出滑板422的上端,导向块421在上端远离头枕2的一侧形成缺口424,调节部43的卡杆431卡在该缺口424内,缺口424的竖向截面为圆弧形。轴套435的竖向截面为圆环形,轴套435位于缺口424内,无论凸柱432被弹性件433松开还是拉紧,轴套435均能稳固地位于缺口424内而不致歪斜卡死。More specifically, as shown in FIG. 4 and FIG. 3 , the upper end of each guide block 421 on the fixed part 42 exceeds the upper end of the slide plate 422 , and the guide block 421 forms a gap 424 on the side away from the headrest 2 at the upper end, and the adjustment part 43 The clamping rod 431 is clamped in the notch 424, and the vertical section of the notch 424 is arc-shaped. The vertical section of the shaft sleeve 435 is circular, and the shaft sleeve 435 is located in the notch 424. Regardless of whether the boss 432 is loosened or tightened by the elastic member 433, the shaft sleeve 435 can be firmly located in the notch 424 without being skewed and stuck. .

如图4所示,导向块421在对应缺口424处设置有导向孔423,导向孔423在朝向头枕2的方向贯通导向块421。导向孔423包括大孔段和小孔段(图未示出),导向孔423中远离头枕2的部分为小孔段,导向孔423中邻近头枕2的部分为大孔段,大孔段与小孔段之间限定出台阶。弹簧设在大孔段内,弹簧的一端止抵在上述台阶上,弹簧的另一端止抵在凸柱432的设置滚轮434的端头上。As shown in FIG. 4 , the guide block 421 is provided with a guide hole 423 at a place corresponding to the notch 424 , and the guide hole 423 penetrates the guide block 421 in a direction toward the headrest 2 . The guide hole 423 includes a large hole section and a small hole section (not shown in the figure). The part of the guide hole 423 away from the headrest 2 is a small hole section, and the part adjacent to the headrest 2 in the guide hole 423 is a large hole section. A step is defined between the segment and the aperture segment. The spring is arranged in the large hole section, one end of the spring stops against the above-mentioned step, and the other end of the spring stops against the end of the setting roller 434 of the boss 432 .

在一些实施例中,如图6和图7所示,儿童安全座椅100的底座3上设有圆形的转孔30,儿童安全座椅100还包括座椅调节机构5,座椅调节机构5包括转盘51,转盘51可转动地设在转孔30内,座椅本体1设在转盘51上,且座椅本体1与底座3之间的转动部件仅包括所述转盘51。In some embodiments, as shown in FIGS. 6 and 7 , the base 3 of the child safety seat 100 is provided with a circular turning hole 30 , and the child safety seat 100 also includes a seat adjustment mechanism 5 . 5 includes a turntable 51, which is rotatably arranged in the turn hole 30, the seat body 1 is arranged on the turntable 51, and the rotating part between the seat body 1 and the base 3 only includes the turntable 51.

可以理解的是,现有的儿童安全座椅上如果座椅本体能够相对底座转动,座椅本体与底座之间通过设置的是转轴。而转轴较细,转轴的截面面积通常不足座椅本体的椅座面积的十分之一,较细的转轴承受的转矩、弯矩过大,转轴易折或者变形,导致座椅本体容易卡死而无法转动。It can be understood that, in the existing child safety seat, if the seat body can rotate relative to the base, a rotating shaft is provided between the seat body and the base. The rotating shaft is thinner, and the cross-sectional area of the rotating shaft is usually less than one-tenth of the seat area of the seat body. The torque and bending moment of the thinner rotating shaft are too large, and the rotating shaft is easy to break or deform, causing the seat body to be easily stuck. Dead and unable to turn.

也有的儿童安全座椅上不仅设置了转轴,转轴上方还设置转盘,该座椅转动时以转轴作为主要转动支撑部件,而以转盘作为辅助支撑部件,这就导致座椅结构复杂、成本较高。Some child safety seats are not only equipped with a rotating shaft, but also a turntable is arranged above the rotating shaft. When the seat is turned, the rotating shaft is used as the main rotating support part, and the turntable is used as the auxiliary supporting part, which leads to a complicated seat structure and high cost. .

而本发明实施例中,通过在座椅本体1和底座3之间设置转盘51,转盘51的截面面积大于等于椅座11面积的十分之一,转盘51面积大、承重能力强,转盘51不易损坏也不易歪斜、卡死,转动平稳、可靠性高。而且由于转盘51的截面面积较大,加工精度要求较低,从而可降低加工成本。In the embodiment of the present invention, by setting the turntable 51 between the seat body 1 and the base 3, the cross-sectional area of the turntable 51 is greater than or equal to one-tenth of the area of the seat 11, and the turntable 51 has a large area and a strong load-bearing capacity. It is not easy to be damaged or skewed or stuck, and it rotates smoothly and has high reliability. Moreover, since the cross-sectional area of the turntable 51 is relatively large, the machining precision is relatively low, thereby reducing the machining cost.

在本发明的一些具体示例中,转盘51的截面面积约为椅座11在水平面上的投影面积的1/5~1/3,优选地,转盘51的截面面积为椅座11在水平面上的投影面积的1/4。这里,转盘51的截面面积指的是转盘51在垂直于其转动轴线的截面上的面积。In some specific examples of the present invention, the cross-sectional area of the turntable 51 is about 1/5 to 1/3 of the projected area of the seat 11 on the horizontal plane. Preferably, the cross-sectional area of the turntable 51 is about 1/4 of the projected area. Here, the cross-sectional area of the turntable 51 refers to the area of the turntable 51 on a cross section perpendicular to its rotation axis.

在一些实施例中,如图8所示,底座3包括:上底壳31和下底壳32,下底壳32盖合在上底壳31的底部,上底壳31与下底壳32之间限定出安装空间。这种空壳结构可降低底座3重量及材料加工成本。In some embodiments, as shown in FIG. 8 , the base 3 includes: an upper bottom case 31 and a lower bottom case 32 , the lower bottom case 32 covers the bottom of the upper bottom case 31 , and the upper bottom case 31 and the lower bottom case 32 The space is limited for installation. This hollow shell structure can reduce the weight of the base 3 and the cost of material processing.

具体地,如图8所示,转孔30设在上底壳31上,转盘51的底端伸入到安装空间内,且转盘51的部分底端支撑在下底壳32上。Specifically, as shown in FIG. 8 , the rotating hole 30 is provided on the upper bottom case 31 , the bottom end of the turntable 51 protrudes into the installation space, and part of the bottom end of the turntable 51 is supported on the lower bottom case 32 .

需要说明的是,现有技术中当座椅本体通过转轴连接在底座上时,转轴与底座的连接处接触应力较大,需要在底座上设置特殊的轴座,或者转轴与底座之间连接轴承。但是轴承的设置增加了零件数量,且底座在轴承安装处结构复杂,成本增加。It should be noted that, in the prior art, when the seat body is connected to the base through a rotating shaft, the contact stress at the joint between the rotating shaft and the base is relatively large, and it is necessary to install a special shaft seat on the base, or to connect the bearing between the rotating shaft and the base. . However, the arrangement of the bearing increases the number of parts, and the structure of the base at the place where the bearing is installed is complicated, and the cost increases.

而本发明实施例中,由于转盘51截面面积较大,转盘51与底座3连接处挤压应力较小,因此转盘51可以直接置于底座3上,不仅节省了零件数量,而且也简化了座椅结构,这也是本发明实施例的儿童安全座椅100的一大优势。However, in the embodiment of the present invention, since the cross-sectional area of the turntable 51 is relatively large, the extruding stress at the joint between the turntable 51 and the base 3 is relatively small, so the turntable 51 can be directly placed on the base 3, which not only saves the number of parts, but also simplifies the seat. This is also a major advantage of the child safety seat 100 in the embodiment of the present invention.

具体地,如图8所示,底座3还包括悬板34,悬板34设在安装空间内,悬板34与上底壳31之间限定出悬挂空间,转盘51的部分边缘夹设在悬挂空间内。这样相当于转盘51由下底壳32提供部分支撑力,还由上底壳31提供另一部分支撑力,转盘51上支撑力分散后,有利于提高整体支撑的平稳性。Specifically, as shown in Figure 8, the base 3 also includes a suspension plate 34, which is arranged in the installation space, and a suspension space is defined between the suspension plate 34 and the upper bottom case 31, and part of the edge of the turntable 51 is sandwiched between the suspension inside the space. This means that the lower bottom shell 32 provides part of the supporting force for the turntable 51, and the other part of the supporting force is provided by the upper bottom shell 31. After the support force on the turntable 51 is dispersed, it is beneficial to improve the stability of the overall support.

在一些实施例中,如图8所示,转盘51上设有挡块511,挡块511设在安装空间内且止挡在上底壳31上。In some embodiments, as shown in FIG. 8 , a stopper 511 is provided on the turntable 51 , and the stopper 511 is arranged in the installation space and stops on the upper bottom shell 31 .

具体地,转盘51的外周缘上设有环形的挡块511,转盘51从上底壳31的下方伸入到转孔30内,然后转盘51通过挡块511卡止在上底壳31上,避免转盘51整个从上底壳31上脱出。Specifically, an annular stopper 511 is provided on the outer periphery of the turntable 51, and the turntable 51 extends into the turn hole 30 from below the upper bottom case 31, and then the turntable 51 is locked on the upper bottom case 31 by the stopper 511, Prevent the turntable 51 from coming out of the upper bottom case 31 entirely.

一些实施例中,如图7所示,底座3上设有多个环绕转盘51设置的第一档位孔36。In some embodiments, as shown in FIG. 7 , the base 3 is provided with a plurality of first gear holes 36 arranged around the turntable 51 .

如图6所示,座椅调节机构5还包括:拉板52和档位保持弹性件53,拉板52设在座椅本体1和转盘51之间,如图9和图6所示,拉板52具有连接端P1和拉动端P2,连接端P1与座椅本体1相连,拉动端P2上设有卡栓521,拉动端P2可在座椅本体1和转盘51之间上下活动,当拉动端P2向下活动时可带动卡栓521插入第一档位孔36,当拉动端P2向上活动时可带动卡栓521拔出。档位保持弹性件53设在座椅本体1和拉动端P2之间,以常驱动拉动端P2向下活动。这里,“常”指的是常态,“常驱动”表示档位保持弹性件53对拉板52具有一个经常朝向某个方向推动的趋势。As shown in Figure 6, the seat adjustment mechanism 5 also includes: a pull plate 52 and a gear holding elastic member 53, the pull plate 52 is arranged between the seat body 1 and the turntable 51, as shown in Figure 9 and Figure 6, pull The plate 52 has a connecting end P1 and a pulling end P2, the connecting end P1 is connected with the seat body 1, the pulling end P2 is provided with a latch 521, the pulling end P2 can move up and down between the seat body 1 and the turntable 51, when pulling When the end P2 moves downward, it can drive the latch 521 to be inserted into the first gear hole 36 , and when the pulling end P2 moves upward, it can drive the latch 521 to be pulled out. The gear holding elastic member 53 is arranged between the seat body 1 and the pulling end P2 to normally drive the pulling end P2 to move downward. Here, "normal" refers to the normal state, and "normal driving" means that the gear holding elastic member 53 has a tendency to push the pulling plate 52 towards a certain direction.
