Description

一种低风阻喷水无骨雨刮 技术领域
本发明属于无骨雨刮技术领域，尤其涉及一种低风阻喷水无骨雨刮。
背景技术
目前无骨雨刮在车上的应用越来越多，市场占比也逐年增长，无疑成为未来雨刮器的主流发展趋势。传统的汽车喷水方式一般是将喷水组件安装在汽车的通风罩板或引擎盖上，使用者执行了雨刮的相关操作后，玻璃水会从喷水组件中喷出覆盖于汽车玻璃窗，然后雨刮胶条执行刮擦功能。这种喷出口角度和位置固定式的喷水方式无疑会干扰驾驶中的司机的视野，且漫射的清洗液没有合理的喷射到雨刮器的刮擦路径上，玻璃水浪费较大。为了解决这一问题，市场上产生了一种将喷水口设置在雨刮刷头上的喷水雨刮，玻璃水可以按需从喷水口喷向雨刮胶条的刮擦路径上，保证刮擦效果的同时，节约了大量的玻璃水。
但是，发明人认为，在雨刮臂上固定喷水组件，无疑会增加了雨刮臂整体的风阻，使得汽车行驶时的喷水无骨雨刮无法保持稳定，不能确保无骨雨刮的喷水路线，特别是在高速行驶时，高风阻的无骨雨刮还可能产出风噪和抖动，一些喷水无骨雨刷会在雨刮臂下方设置牵拉弹簧保证雨刮胶条与车玻璃之间的贴合力，但是这种设计无疑会加重无骨雨刷胶条的磨损，严重限制了无骨雨刮胶条的使用寿命。为此，设计出一种低风阻喷水无骨雨刮。
需要说明的是，在上述背景技术部分公开的信息仅用于加强理解本公开的背景，并且因此可以包括不构成现有技术的信息。
发明内容
发明人通过研究发现，受喷水无骨雨刮使用环境的影响，在雨刮臂上固定喷水组件，会增加雨刮臂整体的风阻，导致喷水无骨雨刷的无法在高速行驶时状态稳定，不能很好地实现喷水雨刮基本的喷水和刮擦车玻璃功能，高风阻的无骨雨刮还可能存在产出风噪和抖动的技术问题。
鉴于以上技术问题中的至少一项，本公开提供了一种低风阻喷水无骨雨刮，具体技术方案如下：
一种低风阻喷水无骨雨刮，包括雨刮臂和附件，雨刮臂前端为装配部，装配部设有缺口；附件包括支架和盖体，支架上表面中部设有轴架，轴架设有轴体，盖体为下端开口的壳体，壳体内部形成结构室，结构室设有轴孔，轴孔与轴体配用构成转动副，轴体的轴线到支架上表面的距离大于轴孔的轴线到盖体下端面的距离，盖体的一端设有延伸向结构室的装配通道，结构室的内壁设有弹性连接臂，弹性连接臂连接有限位件，限位件伸入装配通道，盖体的外表面设为导流斜面，导流斜面为流线型的曲面结构，导流斜面的高处设有导流脊，在附件的外侧设有喷水组件，喷水组件的高度低于导流脊。
在本公开的一些实施例中，还包括两根平行设置的弹片，两根弹片夹持配合有胶条构成弹片胶条组件，支架连接于弹片长轴线的中部区域，两根弹片的上方套设有护套，弹片胶条组件的两端配设有端盖。
在本公开的一些实施例中，所述护套和端盖的外表面也设为流线型的曲面结构，曲面的高处设有导流脊Ⅱ。
在本公开的一些实施例中，所述弹片端部外侧设有开口槽，端盖的一端为与弹片胶条组件配用的插入端，插入端沿端盖的长中线设有弹片避位盲孔，弹片避位盲孔的下方设有胶条避位开口，弹片避位盲孔两侧相对设有空腔，空腔在靠近插入端的一侧延伸出弹性拨片，弹性拨片的根部靠近端盖外侧，弹性拨片的端部靠近弹片避位盲孔，空腔下方开设有窗口。
在本公开的一些实施例中，所述喷水组件内部设有管路，管路的中部设有储水室，储水室下部设有可拆卸的密封端盖，密封端盖上设有喷水口Ⅰ，储水室的两侧相对设有出水通道，出水通道配设有喷水口Ⅱ，喷水口Ⅱ射流方向与喷水口Ⅰ射流方向的夹角呈锐角。
在本公开的一些实施例中，所述喷水组件配设有罩壳，罩壳设有喷水窗口。
在本公开的一些实施例中，所述出水通道的端部设有球形空腔，球形空腔内配设有球头，球头与球形空腔构成球面副，球头设有通孔，通孔与出水通道水路接通。
在本公开的一些实施例中，所述球头具有类球缺体结构，通孔设于类球缺体结构的端面处，通孔的出水端设有线形喷口，线形喷口最窄处的尺寸不大于通孔最宽处的尺寸。
在本公开的一些实施例中，所述球头在类球缺体结构的端面处设有蓄水腔， 通孔设于蓄水腔的中部。
在本公开的一些实施例中，所述蓄水腔为通槽，通槽的槽高不小于球头的半径。
相比较现有技术而言，本发明具有以下有益效果：
1.本低风阻喷水无骨雨刮通过在附件的外侧连接有喷水组件，喷水组件的高度低于导流脊Ⅰ，使得装配喷水组件后的附件因为导流脊Ⅰ的存在风阻大大降低，降低了整个雨刮系统在车辆高速行驶时的运行负载，减少了无骨雨刮的风噪和抖动；
2.本低风阻喷水无骨雨刮通过导流斜面和导流脊Ⅰ的设置，胶条和车玻璃之间的压力可以由车前方的风压提供，车速越快则压力越大，有效降低了车辆较慢或停止时，雨刮臂对胶条的压迫，延长了胶条的使用寿命，同时，因为压力较小，胶条在刮刷换向时，噪音较小，提升了驾驶员的驾驶体验；
3.本低风阻喷水无骨雨刮通过导流斜面和导流脊Ⅰ的设置，不再需要在雨刮臂的下面设置牵拉弹簧保证胶条和车玻璃之间的压力，节约了弹簧等生产材料，相关的设计成本，降低了制造成本；
4.本低风阻喷水无骨雨刮通过限位件和缺口的配用设置，仅需使用者拨开弹性连接臂即可实现附件和雨刮臂之间的连接解除，操作方便，不需要使用者学习雨刮器相关的复杂的装配知识即可自主装配，降低了对使用者的要求，节约了使用者的成本。

具体实施方式：
为了更好地了解本发明的目的、结构及功能，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。
本文中为部件所编序号本身，仅用于区分所表述的对象，不具有任何顺序或技术含义。而本公开中所说“连接”，如无特殊具体说明，均包括直接和间接的“连接”。在本申请的描述中，需要理解的是，方位术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简要描述，而不是指示或暗示所指的装置或单元必须具有特定的方位、以特定的方位构成和操作，因此不能理解为对本申请的限制。
如附图部分的图1至图10所示，设计出一种低风阻喷水无骨雨刮，包括雨刮臂1和附件2，雨刮臂1的前端为和附件2组装用的装配部，装配部设有缺口11；附件2包括支架21和盖体22，支架21上表面中部设有轴架211，轴架211设有轴体2111，盖体22为下端开口的壳体，壳体内部形成结构室，结构室设有轴孔221，轴孔221与轴体2111配用构成转动副，轴体2111的轴线到支架21上表面的距离大于轴孔221的轴线到盖体22下端面的距离，盖体22的一端设有延伸向结构室的装配通道222，结构室的内壁设有弹性连接臂223，弹性连接臂223连接有限位件2231，限位件2231伸入装配通道222，使用时，仅需使用者拨开弹性连接臂223即可实现附件2和雨刮臂1之间的连接解除，操作方便，不需要使用者学习雨刮器相关的复杂的装配知识即可自主装配，降低了对使用者的要求，节约了使用者的成本；盖体22的外表面设为导流斜面224，导流斜面224 为流线型的曲面结构，导流斜面224的高处设有导流脊Ⅰ2241，在附件2的外侧设有喷水组件3，喷水组件3的高度低于导流脊Ⅰ2241，使得装配喷水组件3后的附件2因为导流脊Ⅰ2241的存在风阻大大降低，降低了整个雨刮系统在车辆高速行驶时的运行负载，减少了无骨雨刮的风噪和抖动，胶条42和车玻璃之间的压力可以由车前方的风压提供，车速越快则压力越大，有效降低了车辆较慢或停止时，雨刮臂1对胶条42的压迫，延长了胶条42的使用寿命，同时，因为压力较小，胶条42在刮刷换向换面时，噪音较小，提升了驾驶员的驾驶体验，同时，不再需要在雨刮臂1的下面设置牵拉弹簧保证胶条42和车玻璃之间的压力，节约了弹簧等生产材料，相关的设计成本，降低了制造成本。
以上实施方式中，列举出5种实施例实现上述技术方案：
实施例1
本实施例是公开一种低风阻喷水无骨雨刮，包括雨刮臂1和附件2，附件2为塑料件，雨刮臂1的前端为和附件2组装用的装配部，装配部设有缺口11；附件2包括支架21和盖体22，支架21上表面中部设有轴架211，轴架211设有轴体2111，盖体22为下端开口的壳体，壳体内部形成结构室，结构室的内壁设有加强筋，结构室设有轴孔221，轴孔221与轴体2111配用构成转动副，支架21的上表面设有限位支撑柱，用以限位转动副的转动幅度，轴体2111的轴线到支架21上表面的距离大于轴孔221的轴线到盖体22下端面的距离，盖体22的一端设有延伸向结构室的装配通道222，装配通道222用以和装配部配用，结构室的内壁设有弹性连接臂223，弹性连接臂223本实施例中可以是和盖体22一体成型的塑料材质，弹性连接臂223连接有限位件2231，限位件2231从侧面伸入装配通道222，使用时，仅需使用者拨开弹性连接臂223，轴向移动附件2，即可实现附件2和雨刮臂1之间的连接解除或装配，操作方便，不需要使用者学习雨刮器相关的复杂的装配知识即可自主装配，降低了对使用者的要求，节约了使用者的成本；盖体22的外表面设为导流斜面224，导流斜面224为流线型的曲面结构，导流斜面224的高处设有导流脊Ⅰ2241，在附件2的外侧一体注塑有喷水组件3，喷水组件3的高度低于导流脊Ⅰ2241，使得装配喷水组件3后的附件2因为导流脊Ⅰ2241的存在风阻大大降低，降低了整个雨刮系统在车辆高速行驶时的运行负载，减少了无骨雨刮的风噪和抖动，胶条42和车玻璃之间的压力可以由车前方的风压提供，车速越快则压力越大，有效降低了车辆较慢或停止时， 雨刮臂1对胶条42的压迫，延长了胶条42的使用寿命，同时，因为压力较小，胶条42在刮刷换向换面时，噪音较小，提升了驾驶员的驾驶体验，同时，不再需要在雨刮臂1的下面设置牵拉弹簧保证胶条42和车玻璃之间的压力，节约了弹簧等生产材料，相关的设计成本，降低了制造成本。
其中，还包括两根平行设置的弹片41，两根弹片41夹持配合有胶条42构成弹片胶条组件4，弹片41与胶条42接触但不固定，支架21连接于弹片41长轴线的中部区域，两根弹片41的上方套设有护套5，弹片胶条组件4的两端配设有端盖6，端盖6套设在弹片胶条组件4上。
实施例2
如图1至图6所示，本实施例是公开一种低风阻喷水无骨雨刮，本实施例与实施例1的区别是，在附件2的外侧连接有喷水组件3，附件2和喷水组件3配设有卡配装置，卡配装置可以是卡槽或弹性卡扣等，所述护套5和端盖6的外表面也设为流线型的曲面结构，曲面的高处设有导流脊Ⅱ51，导流脊Ⅱ51和导流脊Ⅰ2241搭配，可以进一步降低雨刮整体的风阻；所述喷水组件3配设有罩壳34，罩壳34设有喷水窗口341，玻璃清洗液由喷水组件3从喷水窗口341穿过喷向车玻璃，罩壳34的设置可以使喷水组件3的外表面更具有整体性，降低气流干扰，降低风阻。
实施例3
如图7所示，本实施例是公开一种低风阻喷水无骨雨刮，本实施例与实施例1的区别是，所述弹片41端部外侧设有开口槽411，端盖6的一端为与弹片胶条组件4配用的插入端，插入端沿端盖6的长中线设有弹片避位盲孔，弹片避位盲孔的下方设有胶条避位开口，弹片避位盲孔两侧相对设有空腔61，空腔61在靠近插入端的一侧延伸出弹性拨片62，弹性拨片62的根部靠近端盖6外侧，弹性拨片62的端部靠近弹片避位盲孔，弹片胶条组件4由插入端穿入后，开口槽411与弹性拨片62的端部形成接触限位，空腔61下方开设有窗口，需要更换胶条时，只需要由窗口伸入，拨开弹性拨片62，使得开口槽411与弹性拨片62的端部脱离接触，即可取下端盖6，更换胶条，将端盖6与弹片胶条组件4重新装配，操作简单，步骤直观清晰。
实施例4
如图8所示，本实施例是公开一种低风阻喷水无骨雨刮，本实施例与实施例 1的区别是，所述喷水组件3内部设有管路31，管路31可以根据喷水组件3的位置设置为盲管或通管，用软管将管路31与雨刮系统的供水部配用，在雨刮臂下选按需选用适当的位置，将各喷水组件3用软管接通，端部的喷水组件3的管路31为盲管，其他的可以是通管，管路31的中部设有储水室32，储水室32下部设有可拆卸的密封端盖321，密封端盖321可以用来清洗储水室32或在储水室32内按需装配单向阀，密封端盖321上设有喷水口Ⅰ3211，储水室32的两侧相对设有出水通道33，出水通道33配设有喷水口Ⅱ331，喷水口Ⅱ331射流方向与喷水口Ⅰ3211射流方向的夹角呈锐角，即可不需要将喷水组件3安装在高的位置就可以向三个方向为车玻璃喷水，进一步降低了风阻。
实施例5
如图9至图10所示，本实施例是公开一种低风阻喷水无骨雨刮，本实施例与实施例1的区别是，所述出水通道33的端部设有球形空腔，球形空腔内配设有球头35，球头35与球形空腔构成球面副，球头35设有通孔351，通孔351与出水通道33水路接通；所述球头35具有类球缺体结构，类球缺体结构可以是标准的球缺结构，也可以是端面为斜面或曲面的近似球缺结构，球缺结构的设置可以使球头35的端部与球形空腔之间形成一个腔室，避免球头35转动时，通孔351的孔口与球形腔室的内壁接触，通孔351被堵死，无法喷水，通孔351设于类球缺体结构的端面处，通孔351的出水端设有线形喷口352，线形喷口352可以配设有喷口壁，可以有效防止球头35过分转动，线形喷口352最窄处的尺寸不大于通孔351最宽处的尺寸，使得玻璃水从通孔351内喷出时，会与线形喷口352的口壁碰撞产生干涉，避免线性喷口因为开口过大失效；所述球头35在类球缺体结构的端面处设有蓄水腔353，通孔351设于蓄水腔353的中部；所述蓄水腔353为通槽，通槽的槽高不小于球头35的半径，进一步避免球头35转动时，通孔351的孔口与球形腔室的内壁接触，通孔351被堵死，无法喷水。
可以理解，本发明是通过一些实施例进行描述的，本领域技术人员知悉的，在不脱离本发明的精神和范围的情况下，可以对这些特征和实施例进行各种改变或等效替换。另外，在本发明的教导下，可以对这些特征和实施例进行修改以适应具体的情况及材料而不会脱离本发明的精神和范围。因此，本发明不受此处所公开的具体实施例的限制，所有落入本申请的权利要求范围内的实施例都属于本发明所保护的范围内。
