Description

汽车座椅及包含其的汽车
本申请要求申请日为2019/8/23的中国专利申请2019107825031的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及汽车技术领域，具体涉及一种汽车座椅及包含其的汽车。
背景技术
目前的座椅功能，一般包含椅座的高度和椅背角度调节，且独立操作。椅座调节的目的是匹配不同分位的驾驶员保证驾驶时候的视野要求，椅背调节的目的是为了提高驾乘的舒适性。但是在现有的汽车座椅中，其原理简图如图1所示，椅背2的旋转中心C设在椅座1的上方。导致的问题是椅背2后向调节过程中椅背2的下端部和椅座1形成一个台阶差，且椅背2向后调节的角度越大，台阶差越大。如图2所示，椅背2向后调节时，椅背2下端部的前凸点A与椅座1形成台阶差S，乘客躯干3在后向转动的过程中后背会被前凸点A顶压，使得无法贴合椅背2，影响乘坐的舒适性。
现有技术中，为了提高在椅背调节后乘坐的舒适性，避免或者降低该台阶差，通过在椅背下端部的前凸点A的区域使用更柔软的发泡，或者造型上采用更大的圆角。或者增加一个新的机构来保证椅座和椅背一起转动，如中国发明专利申请“CN109050355A”通过在常规座椅的滑轨下端增加额外一个机构，用于驱动椅座角度，或者如另一个中国发明专利申请“CN107072396A”采用多连杆的方式。虽然以上几种方式都可以提高座椅的舒适性，但是它们不是增加包覆材料就是增加额外的机构，不仅没有降低椅背与椅座之间形成的台阶差，而且增加了座椅的生产成本。

具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在以下的实施例范围之中。
实施例1
如图3-6所示，本发明的一种汽车座椅，该汽车座椅包括椅座1和椅背2以及椅背调节机构，椅背调节机构包括旋转部，旋转部设在椅背2的下端；旋转部用于绕椅座1的后端部转动，以使椅背2与椅座1之间的角度发生改变，且旋转部的旋转中心位于椅座1的上端面的下方。
如图9所示，本发明通过将椅背2的旋转中心设在椅背2的下端，且位于椅座1的上端面的下方，可以使椅背2在旋转时，椅背2的下端部与椅座1的上端面形成很小的台阶差，甚至不会有台阶差。这样就可以保证椅背2的下端部基本不会抵压乘员的后背，提高了乘员后背与椅背2的贴合性，保证了乘坐的舒适性。
该汽车座椅还包括椅座调节机构，椅座调节机构用于调节椅座1以实现椅座1在高度方向上的升降调节。在本实施例中，通过设置椅座调节机构，可以调整座椅的高度，满足不同身高乘员的需求，进一步提高乘坐的舒适性。
在本实施例中，椅背调节机构与椅座调节机构在调节时相互独立。这样可以根据乘员要求进行调节，也可以避免其中一个损坏，另一个无法调节的 情况发生。
在本实施例中，旋转部上安装设有第一调角器7，第一调角器7的固定部安装在椅座1上，第一调角器7的转动部安装在旋转部上。通过在椅背2的旋转部上安装调角器，可以方便、定量对椅背2进行调节。
椅座1包括两个对称设置的侧壁板101，两个侧壁板101的后端均设有第一通孔102，椅背2包括两个对称设置的背壁板201，每个背壁板201的下端固定有连接板5，连接板5上设有第二通孔501；第一调角器7的固定部和第一调角器7的转动部分别安装在第一通孔102和第二通孔501上。在本实施例中，椅座1的旋转部相当于设置在连接板5的第二通孔501处，由于旋转部与第一调角器7的转动部固定连接，通过驱动第一调角器7转动，实现椅背2绕椅座1旋转。
椅座1和椅背2均是通过骨架结构装配而成，通过简单的侧壁板101和背壁板201实现座椅的装配，不仅降低了座椅的重量，而且还降低了生产成本。
两个侧壁板101之间设有第一连杆11，第一连杆11的两端分别与两个第一调角器7的转动部固定连接。在本实施例中，在两个侧壁板101上均设有一个第一调角器7，第一连杆11的两端分别与两个第一调角器7的转动部固定。这样就可以通过第一连杆11将两个侧壁板101连接，可以在驱动其中一个侧壁板101上的调角器工作时，带动另一侧的调角器工作，不用两侧同时驱动。同时，可以在侧壁板101的前端设有第二连杆12，第二连杆12可以使两个侧壁板101在移动时保持稳定。
在本实施例中，如图5-6所示，椅座1调节机构包括两个第一支架3、两个第二支架4、第二调角器8，两个第一支架3对应设在椅座1的前端部的两侧，两个第二支架4对应设在椅座1的后端部的两侧；其中，第一支架3铰接在椅座1的前端部，第二支架4的上端部绕椅背2的旋转中心自由转动，第一支架3和第二支架4的下端分别铰接在座椅安装座6上；第二调角 器8用于调节第一支架3或第二支架4与椅座1的角度，以实现椅座1在高度方向上的升降调节。
第二支架4的上端设有容置孔401，第一调角器7的固定部穿过容置孔401且与容置孔401相对自由转动；第二支架4上设有齿形部402，第二调角器8的固定部安装在椅座1上，第二调角器8的转动部上设有与齿形部402的齿啮合的齿轮801，齿轮801通过第二驱动机构10驱动第二支架4转动以实现椅座1在高度方向上的升降调节。其中，为了方便第二支架4转动顺畅，容置孔401为圆形通孔，在圆形通孔内还设有衬套15，第一调角器7的固定部穿设并固定在衬套15内，衬套15与容置孔401相对自由转动。
椅座1调节机构通过采用两个第一支架3、两个第二支架4、椅座1、座椅安装座6共同组成两组四连杆机构，两组四连杆机构通过第二调角器8进行调节，通过改变椅座1与第一支架3或第二支架4之间的角度来实现椅座1在高度方向上的升降调节。通过第二调角器8改变第二支架4与椅座1的角度，可以在第二支架4上设有一个齿形部402，通过第二调角器8上的齿轮801的转动来实现第二支架4的转动，同时为了使椅座1一起转动，在第二支架4上设有与第一调角器7的固定部相对自由转动的容置孔401，使得第二支架4在转动过程中带动椅座1一起转动，实现第二支架4与椅座1之间的夹角的改变调节椅座1的高度。
在本实施例中，座椅安装座6上设有第一铰接座13和第二铰接座14，第一支架3和第二支架4的下端分别铰接在第一铰接座13和第二铰接座14上。
这样是为了方便第一支架3和第二支架4下端部的铰接，通过在座椅安装座6上设置铰接座。
在本实施例中，第一调角器7和第二调角器8分别设有第一驱动机构9和第二驱动机构10，用于驱动第一调角器7的转动部转动。第一驱动机构9和第二驱动机构10都可以为手动调节机构或自动调节机构，也可以在椅座 1两侧分别安装手动调节机构和自动调节机构，根据需求进行选择。
本发明还公开了一种汽车，该汽车包含有如上的汽车座椅。
实施例2
本实施例与实施例1相比，主要不同之处在于椅座1调节机构结构的不同。如图7-8所示，椅座1调节机构包括两个第一支架3、两个第二支架4、第二调角器8，两个第一支架3对应设在椅座1的前端部的两侧，两个第二支架4对应设在椅座1的后端部的两侧；其中，第一支架3铰接在椅座1的前端部，第二支架4的上端部绕椅背2的旋转中心自由转动，第一支架3和第二支架4的下端分别铰接在座椅安装座6上；第二调角器8用于调节第一支架3或第二支架4与椅座1的角度，以实现椅座1在高度方向上的升降调节。第二支架4的上端设有容置孔401，第一调角器7的固定部穿过容置孔401且与容置孔401相对自由转动；椅座1调节机构还包括齿条板16，齿条板16的两端分别铰接在第一支架3的上端铰接点和第二支架4的下端铰接点上；第二调角器8的转动部上设有与齿条板16的齿啮合的齿轮801，齿轮801通过驱动机构驱动齿条板16转动以实现椅座1在高度方向上的升降调节。其中，为了方便第二支架4转动顺畅，容置孔401为圆形通孔，在圆形通孔内还设有衬套15，第一调角器7的固定部穿设并固定在衬套15内，衬套15与容置孔401相对自由转动。第二调角器8在安装时，安装在侧壁板101的外侧，齿轮801穿过侧壁板101上的第三通孔103与齿形部402的齿啮合，侧壁板101另一侧设有限制齿轮801转轴的限位件17。
在本实施例中，主要是通过第二调角器8改变第一支架3与椅座1的角度来调节座椅高度，通过增加一个齿条板16，通过第二调角器8上的齿轮801的转动来实现齿条板16的上端部旋转，同时带动第一支架3的转动，在第二支架4上设有与第一调角器7的固定部相对自由转动的容置孔401，使得第一支架3在转动过程中带动椅座1一起转动，实现第一支架3与椅座1之间的夹角的改变调节座椅的高度。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
