Description

一种出风口 技术领域
本发明涉及车辆内饰件领域，更具体地涉及一种出风口。
背景技术
为了调节车内环境温度，车辆仪表板或者副仪表板上通常布置有空调出风口。随着内饰造型的简洁化，对出风口外观开口的细长化要求逐渐流行。
常规出风口通过前后两排叶片对出风的上下与左右方向分别控制，然而，当出风开口细长化后，使用水平叶片进行上下导风时，由于叶片厚度的影响，出风有效面积会大大减小，并且其导向性也会受到影响。
发明内容
为了解决现有技术中细长化出风口的叶片布置空间受限以及有效出风面积和导向性范围受到影响的问题，本发明提供一种出风口。
本发明提供的出风口在满足内饰造型简洁化要求的同时，采用移动导风块代替叶片，来进行上下导风，增大了有效出风面积。进一步地，本发明在控制左右导风的叶片上设置肋片，保证了良好的导向性。

具体实施方式
以下结合附图和实施例对本发明做进一步描述，应该理解，以下实施例仅用以说明而并非限制本发明。
1.实施例一
根据本发明的出风口，如图1-2所示。出风口1包括上壳体21、下壳体22、导风块3以及导风叶片组4。上壳体21与下壳体22合并之后，两侧留有细长的长方形缺口，一侧为进风侧23，另一侧为出风侧24。导风块3及导风叶片组4装配于壳体内部，且导风块3将壳体空腔分割为上下两部分。如图3A-3C和8A-8C所示，导风块3上下移动时，壳体空腔上下两部分的比例能够发生变化，从而调节出风口1上下方向的吹风。
如图5A所示，导风块3具有沿导风叶片轮廓延伸的井部31，导风叶片组4贯穿于井部31内部并且可以在井部31内左右转动以调节出风口1左右方向的吹风，如图4A-4B所示。井部31开口的侧部包括多个连续的曲面32，由于井部的设置是为了避让叶片的运动包络面，因而曲面32的形状与叶片运动包络面的形状基本一致。曲面的数量与导风叶片的数量一致，且单个曲面的两端对应单个导风叶片的极限转动位置。
如图6和图7所示，导风叶片组4中的叶片设有多个不同高度的肋片41，肋片41用于填补导风叶片之间及导风叶片组4与导风块3之间的缝隙，使壳体内部的气道更平顺。肋片41的外轮廓与导风块同侧外表面的外轮廓一致，且相邻叶片上的肋片交错排布，处于同一高度的肋片为一组。当导风块3处于不同高度时，至少有一组肋片与导风块3的井部31开口外围的上表面或下表面基本对齐。
导风叶片上还设有沿竖直方向延伸的叶片转轴42以及叶片连杆转轴44，其中，单个叶片可绕叶片转轴42转动，多个叶片则通过与叶片连杆转轴44连接的叶片连杆43组成导风叶片组4。
当出风口1正向吹风时，如图8B所示，导风块3位于壳体的中部，壳体空腔被导风块3分割为上下均等的两部分。气流5从壳体进风侧23进入壳 体后，被导风块3上下均等地分开，经过导风块3及导风叶片组4后在壳体出风侧24汇合，由于上下侧的气流量相等，气流5沿着水平方向在壳体出风侧24吹出。其中，肋片41填补了导风块3中部的缺口，使壳体内部的气道平滑。
当出风口1向上吹风时，如图8A所示，导风块3位于壳体上部，下壳体22的内壁与导风块3一同形成了在壳体出风侧24处向上的出口，气流5位于导风块3的下部，并沿着向上的方向从壳体出风侧24吹出。当导风块3与上壳体21内壁贴紧时，壳体空腔的上部被完全封闭，向上吹风角度达到极限值，有效增大了出风面积。
当出风口1向下吹风时，其原理与向上吹风相同。如图8C所示，导风块3位于壳体下部，上壳体21的内壁与导风块3一同形成了在壳体出风侧24处向下的出口，气流5位于导风块3的上部，并沿着向下的方向从壳体出风侧24吹出。当导风块3与下壳体22内壁贴紧时，壳体空腔的下部被完全封闭，向下吹风角度达到极限值，有效增大了出风面积。
当出风口1左右吹风时，如图9A-9C所示，所述导风叶片组4左右转动，气流5经过壳体与导风块3的间隙被导风叶片导向发生左右偏转，从而在壳体出风侧24吹出左右导向的气流。
导风叶片组4沿叶片转轴42的左右转动与导风块3的上下运动互不干涉，分别对气流的左右和上下进行导向。当出风口1向上吹风且向右吹风时，如图10所示，导风块3位于壳体的上部，导风叶片组4向右倾斜，使气流5以叶片的倾斜角度向右上方向导向。肋片41减少了导风块井部31暴露于气道中的缺口，使壳体内部的气道更平顺，使导风叶片组4有效导向并降低气流噪音。
2.实施例二
如图11-12所示，本发明所述的出风口6包括上壳体71、下壳体72、导风块8以及导风叶片组9。导风叶片组9具有沿水平方向延伸的叶片转轴93，叶片转轴93延伸至上壳体71以及下壳体72的两侧。将叶片转轴93布置在壳体侧面，便于在壳体侧面布置电机(图未示)，从而减少出风口高度方向占的空间。上壳体71与下壳体72合并之后，两侧留有细长的长方形缺口，一侧为进风侧73，另一侧为出风侧74。
对比于实施例一，如图15-17所示，本实施例的导风叶片组9为两个导 风叶片串91和92，叶片串上包括多个相对于转轴93倾斜布置的叶片。如图14A-14B所示，导风叶片串91和92绕叶片转轴93转动以调节出风口左右方向的吹风。在本实施例中，导风块8具有沿纵向延伸的井部81，且导风块8的两侧设有U形槽82和方槽83，叶片转轴93安装于U形槽82中。另外，两个导风叶片串91和92之间设有隔板10，隔板10上设有隔板凸块101，该隔板凸块101容置于方槽83中，使得导风块8能够相对于导风叶片串91和92上下移动，如图13A-13C和14C和14D所示，可以调节出风口上下方向的吹风。
如图18A-18C和19A-19C所示，随着叶片串91和92绕转轴93转动，当叶片的延伸方向相对于与转轴93垂直的方向向右偏时，出风口的吹风方向为向右；当叶片的延伸方向相对于与转轴93垂直的方向向左偏时，出风口的吹风方向为向左；当叶片的延伸方向平行于与转轴93垂直的方向时，出风口的吹风方向为向中间。
导风叶片串91和92绕叶片转轴93的转动与导风块8的上下运动互不干涉，分别对气流的左右和上下进行导向。当出风口1向上吹风且向右吹风时，如图20所示，导风块8位于壳体的上部，导风叶片串91和92向右倾斜，使气流5以叶片的倾斜角度向右上方向导向。
以上所述的，仅为本发明的较佳实施例，并非用以限定本发明的范围，本发明的上述实施例还可以做出各种变化。即凡是依据本发明申请的权利要求书及说明书内容所作的简单、等效变化与修饰，皆落入本发明专利的权利要求保护范围。本发明未详尽描述的均为常规技术内容。
