车轮 技术领域
本申请涉及车辆技术领域，具体而言，涉及一种车轮的结构改进。本申请要求于2019年7月23日提交至中国国家知识产权局、申请号为201910667209.6、发明名称为“车轮”的专利申请的优先权。
背景技术
现有技术中通常采用例如气体保护焊和埋弧焊的传统的焊接方式固定轮辋和轮辐，传统的焊接方式的热影响区域范围大，会造成车轮本身的强度降低，导致车轮的结构稳定性差，并且传统的焊接方式制造形成的车轮上的焊道结构的结构不合理，由于焊道结构的高度过大，会影响到轮胎的安装，造成漏气现象，易发生安全事故；现有技术中，一般会采用增加一道车加工的工序，车掉焊道结构的过高部分，这样增加了车轮制造工艺的烦琐性，此外，在对车轮进行径向载荷试验时，焊道结构的端部容易出现裂纹，进而说明现有的焊接方式加工制造的车轮的结构不稳定，无法满足车轮具有较长寿命的使用要求。
发明内容
本申请的主要目的在于提供一种车轮，以解决现有技术中的通过传统的焊接方式对轮辋和轮辐焊接时形成的焊道结构不合理，从而导致车轮的结构稳定性差，无法满足轮辋和轮辐的焊接强度要求，而导致两者的连接稳定性差，影响车轮的使用安全性以及使用寿命的问题。
为了实现上述目的，本申请提供了一种车轮，包括：轮辋，轮辋的轴向一端的表面形成第一连接表面；轮辐，轮辐的轴向一端的表面的部分形成第二连接表面，轮辐通过第二连接表面与第一连接表面激光焊接，且在第一连接表面和第二连接表面的接触位置处形成有用于固定连接轮辋和轮辐的焊道结构，焊道结构由轮辋的部分和轮辐的部分熔融后连接形成。
进一步地，轮辋包括相连接的轮辋本体和折弯翻边，其中，折弯翻边的朝向轮辐一侧的端面形成第一连接表面，第一连接表面与第二连接表面面面贴合，且焊道结构位于第一连接表面和第二连接表面所覆盖的区域内。
进一步地，轮辋包括相连接的轮辋本体和折弯翻边，其中，折弯翻边的朝向轮辐一侧的端面形成第一连接表面，第一连接表面与第二连接表面面面贴合，且焊道结构的在轮辋的径向方向上的宽度大于或等于第一连接表面在轮辋的径向方向上的宽度。
进一步地，折弯翻边为一个，折弯翻边绕轮辋本体的周向连续延伸，第二连接表面呈与折弯翻边适配的环形。
进一步地，轮辐的一部分朝向轮辋凸出设置，以形成环形凸起，折弯翻边与环形凸起适配性贴合。
进一步地，折弯翻边为多个，多个折弯翻边绕轮辋本体的周向间隔设置，第二连接表面包括绕轮辐的周向间隔设置的多段子连接表面，多个折弯翻边与多段子连接表面一一对应配合。
进一步地，轮辐的一部分朝向轮辋凸出设置，以形成多个凸起结构，多个折弯翻边与多个凸起结构一一对应地适配性贴合。
进一步地，焊道结构的延伸路径与折弯翻边的周向延伸路径相同，且焊道结构的长度与折弯翻边的长度相等。
进一步地，折弯翻边垂直于轮辋本体。
进一步地，第一连接表面和第二连接表面均为平面。
应用本申请的技术方案，将轮辋通过激光焊接的方式与轮辐固定连接，激光焊接的热影响区域较小，且轮辋的第一连接表面和轮辐的第二连接表面之间的配合确保了轮辋和轮辐具有足够的接触面积，从而激光焊接后有利于提高轮辋和轮辐的焊接处的连接强度，进而有利于提升车轮的结构强度，确保了车轮具有很好的使用安全性和较长的寿命；此外，在轮辋和轮辐的焊接处形成的焊道结构由轮辋的部分和轮辐的部分共同形成，这种焊道结构不仅微小而且稳固，这是因为激光焊接高效精密，且对两者的破坏小，而且轮辐的部分和轮辋的部分熔融后连接形成的焊道结构的整体结构规整，焊道结构的强度大幅提升，使得车轮受外力冲击时不易断裂，大大地提升了轮辋和轮辐的连接稳定性。
不仅如此，激光焊接能够用于对高强度的材料进行焊接，且激光焊接具有焊接时间短和焊接能耗低的特性，从而有利于提升车轮的生产效率和有利于降低车轮的生产成本，此外，激光焊接的烟尘较小，从而为操作者提供更好的工作环境和保护环境。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了解决现有技术中的通过传统的焊接方式对轮辋和轮辐焊接时形成的焊道结构不合理，从而导致车轮的结构稳定性差，无法满足轮辋和轮辐的焊接强度要求，而导致两者的连接稳定性差，影响车轮的使用安全性以及使用寿命的问题，本申请提供了一种车轮。
实施例一
如图1至4所示，车轮包括轮辋10和轮辐20，轮辋10的轴向一端的表面形成第一连接表面11，轮辐20的轴向一端的表面的部分形成第二连接表面21，轮辐20通过第二连接表面21与第一连接表面11激光焊接，且在第一连接表面11和第二连接表面21的接触位置处形成有用于固定连接轮辋10和轮辐20的焊道结构100，焊道结构100由轮辋10的部分和轮辐20的部分熔融后连接形成。
将轮辋10通过激光焊接的方式与轮辐20固定连接，激光焊接的热影响区域较小，且轮辋10的第一连接表面11和轮辐20的第二连接表面21之间的配合确保了轮辋10和轮辐20具有足够的接触面积，从而激光焊接后有利于提高轮辋10和轮辐20的焊接处的连接强度，进而有利于提升车轮的结构强度，确保了车轮具有很好的使用安全性和较长的寿命；此外，在轮辋10和轮辐20的焊接处形成的焊道结构100由轮辋10的部分和轮辐20的部分共同形成，这种焊道结构100不仅微小而且稳固，这是因为激光焊接高效精密，且对两者的破坏小，而且轮辐20的部分和轮辋10的部分熔融后连接形成的焊道结构100的整体结构规整，焊道结构100的强度大幅提升，使得车轮受外力冲击时不易断裂，大大地提升了轮辋10和轮辐20的连接稳定性。
不仅如此，激光焊接能够用于对高强度的材料进行焊接，且激光焊接具有焊接时间短和焊接能耗低的特性，从而有利于提升车轮的生产效率和有利于降低车轮的生产成本，此外，激光焊接的烟尘较小，从而为操作者提供更好的工作环境和保护环境。
需要说明的是，本申请提供的车轮的轮辋10和轮辐20的装配位置关系，能够极大地提升车轮的外观美感，即作为全表面车轮，轮辐20的面积会大于轮辋10所围成的区域的面积，以实现轮辐20覆盖轮辋10的效果，当用户从轮辐20的一侧沿轴向纵观整个车轮时，不会看到轮辋10，因此，同样提升了使用本申请提供的车轮的车辆的美观性。
如图2和图4所示，轮辋10包括相连接的轮辋本体12和折弯翻边13，其中，折弯翻边13的朝向轮辐20一侧的端面形成第一连接表面11，第一连接表面11与第二连接表面21面面贴合，且焊道结构100位于第一连接表面11和第二连接表面21所覆盖的区域内。这种位置的焊道结构100不仅能够确保轮辋10和轮辐20具有足够的连接强度，以使后期车轮能够承受足够大的冲击载荷，确保车轮的正常使用，提升了车轮的实用性，而且从车轮的外观上，轮辋10和轮辐20的连接处不存在明显的异性结构，因此，大大地提升了车轮的外观美感，确保了批量生产的车轮的外观规整性，提升用户的使用满意度。此外，第一连接表面11与第二连接表面21面面贴合则能够保证轮辋10和轮辐20充分接触，保证两者之间具有足够的接触面积，车轮受到冲击时，防止轮辋10和轮辐20的接触面上出现应力集中而导致车轮损坏，进一步提升了车轮的使用稳定性。
当然在本申请的一个未图示的可选实施例中，轮辋10包括相连接的轮辋本体12和折弯翻边13，其中，折弯翻边13的朝向轮辐20一侧的端面形成第一连接表面11，第一连接表面11与第二连接表面21面面贴合，且焊道结构100的在轮辋10的径向方向上的宽度大于或等于第一连接表面11在轮辋10的径向方向上的宽度。这种形式和位置的焊道结构100则使得轮辋10和轮辐20的接触面的区域被充分的激光焊接，使得焊道结构100占有更大的区域而极大地提升了轮辋10和轮辐20的连接稳定性，使得车轮能够作为一个规整的整体应对各种强度的载荷冲击时，轮辋10和轮辐20始终不会在焊道结构100的位置处发生断裂现象。
在本申请提供的可选实施例中，折弯翻边13为一个，折弯翻边13绕轮辋本体12的周向连续延伸，第二连接表面21呈与折弯翻边13适配的环形。这种结构形式的轮辋10能够确保与轮辐20之间具有足够的接触面积，确保轮辋10在周向的各个位置处均能受到轮辐的支撑，提升了车轮结构的整体稳固性。
当然，在本申请的一个未图示的可选实施例中，在确保轮辋10和轮辐20具有足够连接强度的前提下，尽可能减少轮辋10的加工制造耗材，以起到减少车轮的加工制造成本以及减轻车轮的整体重量的目的，折弯翻边13为多个，多个折弯翻边13绕轮辋本体12的周向间隔设置，第二连接表面21包括绕轮辐20的周向间隔设置的多段子连接表面，多个折弯翻边13与多段子连接表面一一对应配合。
可选地，折弯翻边13垂直于轮辋本体12。这种结构形式的轮辋10不仅便于加工制造，而且有利于增加轮辐20的第二连接表面21与轮辋10的第一连接表面11之间的贴合效果。
同样考虑到轮辋10和轮辐20的面面贴合效果，同时又便于轮辋10和轮辐20的加工制造，优选地，第一连接表面11和第二连接表面21均为平面。
可选地，焊道结构100的延伸路径与折弯翻边13的周向延伸路径相同，且焊道结构100的长度与折弯翻边13的长度相等。这样，进一步提升了轮辋10和轮辐20之间的焊接稳定性。
实施例二
如图5至图8所示，该实施例与实施例一的区别在于，轮辐20的一部分朝向轮辋10凸出设置，以形成环形凸起22，折弯翻边13与环形凸起22适配性贴合。这样，即确保了轮辋10和轮辐20之间面面贴合的可靠性，同时环形凸起22与折弯翻边13还能够起到对轮辋10和轮辐20装配时的防呆安装作用，有效地确保了轮辋10和轮辐20的轴心线共线而确保车轮成为一个回转体。
更重要的是，轮辐20的一部分朝向轮辋10凸出设置，能够有效地增大轮辐20和轮辋10之间相对的端面在连接接触位置处的间隙，这样便为对两者的激光焊接作业提供了足够的操作空间，确保了操作人员对两者稳定、可靠地激光焊接。
当然，在本申请的一个未图示的可选实施例中，同样在确保轮辋10和轮辐20面面贴合连接稳定的同时，也能够起到对轮辋10和轮辐20装配时的防呆安装作用，还能够提成车轮的外观艺术设计感，轮辐20的一部分朝向轮辋10凸出设置，以形成多个凸起结构，多个折弯翻边13与多个凸起结构一一对应地适配性贴合。
