车门铰链机构作为车辆的车门与车身之间的连接件，在车门开关运动中起到关键的作用，从而影响人们对车辆的使用舒适性，使用舒适性可指车门的开度能否满足使用者需求、车门开关时是否存在不顺畅、安全性低等。
目前驾驶室的车门可为旋转门、蝴蝶门等，主要采用单转轴铰链机构，且单转轴固定在车身范围内，导致车门开启角度有限，车门的最大开启角度不会超过90°，无法满足客户大角度开启需求，从而影响司机上下车，也极易发生司机与车门发生碰撞而受伤等情况，也容易限制售后维修空间。
以旋转门为例，本申请提出一种车门联动铰链机构，用于连接车辆的车身和车门。
参照图1至6，在本申请实施例中，该车门联动铰链机构包括车门安装座10、车身安装座20以及弯臂50；车门安装座10固设于车门；车身安装座20固设于车身；弯臂50具有第一端51和第二端52，第一端51与车门安装座10可转动连接，第二端52与车身安装座20可转动连接。如此能够以第一端51与车门安装座10的旋转点、第二端52与车身安装座20的旋转点运动，而使得车门能够具有较大的开门角度，开度能达到160°，从而满足客户大角度开启需求，提升客户的使用舒适性的使用安全性。
弯臂50可为铸造件，能够提高了车门联动铰链机构的整体强度和刚度，从而提升车门开启的使用舒适性；弯臂50作为弯曲的连接件，且第一端51能够与车门安装座10转动连接、第二端52能够与车身安装座20转动连接，便于在满足大角度开启的同时，车门关闭时，车门联动铰链机构整体结构紧凑，体积小，能够缩小装配空间。
通过第一端51与车门安装座10可转动连接，第二端52与车身安装座20可转动连接来实现车门大角度开启，可以理解的，通过第一端51先与车门安装座10转动连接，实现车门的小角度开启，再通过第二端52与车身安装座20转动连接，实现车门的大角度开启；或者，通过第二端52先与车身安装座20转动连接，实现车门的小角度开启，再通过第一端51与车门安装座10转动连接，实现车门的大角度开启；亦或者，第一端51与车门安装座10转动连接，同时，通过第二端52与车身安装座20转动连接，实现车门的大角度开启，满足客户的不同开度需求，还能够防止车门开度有限而导致客户和车门发生碰撞等情况发生。
本申请技术方案中，通过采用弯臂50与车门安装座10、车身安装座20的可转动连接，使得车门的开启通过设置两个旋转点而具有较大的开门角度，开度能达到160°，从而满足客户大角度开启需求，提升客户的使用舒适性和使用安全性。其中，弯臂50作为弯曲的连接件，并具有第一端51和第二端52，第一端51能够与车门安装座10转动连接、第二端52能够与车身安装座20转动连接，便于在满足大角度开启的同时，车门关闭时，车门联动铰链机构整体结构紧凑，体积小，从而缩小装配空间。
在一实施例中，车门打开时，弯臂50先后具有第一端51与车门安装座10相对转动、第二端52与车身安装座20相对静止的第一运动状态，以及第一端51与车门安装座10相对静止、第二端52与车身安装座20相对转动的第二运动状态。可以理解的，车门开启时，施加力于车门，使得车门先通过车门安装座10与弯臂50的第一端51转动连接，此时，弯臂50的第二端52与车身安装座20相对静止，即第二端52与车身安装座20成为一整体，而通过车身安装座20与车身的固定连接，使第二端52与车身相对静止，车门开启角度的范围可为0°至80°，客户可根据需求进行小角度的切换。
当客户有大角度开启需求时，继续施加力于车门，使得车门通过车门安装座10与弯臂50的第一端51相对静止而成为一整体，再次施加力于车门，此时，弯臂50的第二端52能够与车身安装座20相对转动，进而加大车门的开启角度，车门开启角度的范围可为80°至160°，满足客户大角度开启需求。
进一步地，在一实施例中，车门联动铰链机构还包括第一限位结构30，第一限位结构30设于弯臂50，车门安装座10设有与第一端51转动连接的第一转轴11，第一转轴11设有第一止位结构；于第一运动状态，第一限位结构30与第一止位结构相错开，以使第一端51相对第一转轴11转动，于第二运动状态，第一限位结构30与第一止位结构相配合，以使第一端51与第一转轴11相对静止。如此设置，能够避免第一端51和车门安装座10的转动出现卡滞，第二端52和车身安装座20的转动出现卡滞，提升车门开启的顺畅性。
弯臂50的第一端51开设有套设第一转轴11的第一连接通孔，第一限位结构30可设于第一连接通孔与第一转轴11之间，例如，沿第一连接通孔的孔壁设置能够固定第一限位结构30的安装位，通过直接作用于铰接处而可靠限制第一端51的旋转运动。
车门安装座10和第一转轴11可通过铆接、嵌接等不可拆卸的连接方式进行固定，能够提高第一端51与车门安装座10连接的可靠性，也可通过螺接、榫卯等可拆卸的连接方式进行固定，方便维护而保证机构的使用可靠性。
第一转轴11与车门安装座10的固定连接，可以限制第一转轴11与车门安装座10之间的轴向相对位移和相对旋转，进而保证于第一运动状态时，第一限位结构30始终与第一止位结构相错开，此时第一端51能够相对第一转轴11转动，于第二运动状态，第一限位结构30始终与第一止位结构相配合，此时第一端51能够与第一转轴11相对静止。从而保证弯臂50的运动可靠性，提升车门开启的顺畅性。
具体地，在一实施例中，第一限位结构30包括第一限位件31和第一弹性件32，第一弹性件32用以使第一限位件31具有靠近第一转轴11的趋势；以使第一限位件31能够与第一转轴11抵接配合，实现车门的可靠开启。第一限位件31可为限位块、限位球状体等，第一弹性件32可为伸缩弹簧、弹性垫等，通过在弯臂50上开设能够容置第一限位件31和第一弹性件32的安装槽，方便第一限位件31和第一弹性件32起到限制第一转轴11与第一端51相对转动的作用。
其中，第一转轴11的周面包括相连接的第一弧面段111和第一平面段112，第一止位结构配置为第一平面段112，第一限位件31的靠近第一转轴11的端面配置为第一限位平面311；于第一运动状态，第一限位平面311与第一弧面段111抵接，于第二运动状态，第一限位平面311与第一平面段112抵接。可以理解的，于第一运动状态，第一限位件31在第一弹性件32的作用下，通过第一限位平面311始终与第一弧面段111滚动抵接，有利于弯臂50与第一转轴11的平稳转动，便于车门平稳开启。
第一弧面段111和第一平面段112相连，即第一弧面段111靠近第一限位平面311的距离小于第一平面段112靠近第一限位平面311的距离，以由第一运动状态切换至第二运动状态时，第一限位平面311在第一弹性件32的作用下，靠近第一平面段112，并由与第一弧面段111的滚动抵接切换至与第一平面段112的平面配合，第一限位平面311始终与第一平面段112的平面配合，确保在第二运动状态时第一转轴11始终与第一端51相对静止而成为一整体，为第二端52与车身安装座20的相对转动做准备。
具体地，沿垂直于第一转轴11的轴线方向凹设有第一避让槽，第一避让槽的槽底壁可为所述第一平面段112。
进一步地，在一实施例中，车门联动铰链机构还包括第二限位结构40，第二限位结构40设于弯臂50，车身安装座20设有与第二端52转动连接的第二转轴21，第二转轴21设有第二止位结构；于第一运动状态，第二限位结构40与第二止位结构相配合，以使第二端52与第二转轴21相对静止，于第二运动状态，第二限位结构40与第二止位结构相错开，以使第二端52相对第二转轴21转动。如此设置，能够避免第一端51和车门安装座10的转动出现卡滞，第二端52和车身安装座20的转动出现卡滞，提升车门开启的顺畅性。
弯臂50的第二端52开设有套设第二转轴21的第二连接通孔，第二限位结构40可设于第二连接通孔与第二转轴21之间，例如，沿第二连接通孔的孔壁设置能够固定第二限位结构40的安装位，通过直接作用于铰接处而可靠限制第二端52的旋转运动。
车身安装座20和第二转轴21可通过铆接、嵌接等不可拆卸的连接方式进行固定，能够提高第二端52与车身安装座20连接的可靠性，也可通过螺接、榫卯等可拆卸的连接方式进行固定，方便维护而保证机构的使用可靠性。
第二转轴21与车身安装座20的固定连接，可以限制第二转轴21与车身安装座20之间的轴向相对位移和相对旋转，进而保证于第一运动状态时，第二限位结构40始终与第二止位结构相配合，此时第二端52能够与第二转轴21相对静止，于第二运动状态，第二限位结构40始终与第二止位结构相错开，此时第二端52能够相对第二转轴21转动。从而保证弯臂50的运动可靠性，提升车门开启的顺畅性。
具体地，在一实施例中，第二限位结构40包括第二限位件41和第二弹性件42，第二弹性件42用以使第二限位件41具有靠近第二转轴21的趋势；以使第二限位件41能够与第二转轴21抵接配合，实现车门的可靠开启。第二限位件41可为限位块、限位球状体等，第二弹性件42可为伸缩弹簧、弹性垫等，通过在弯臂50上开设能够容置第二限位件41和第二弹性件42的安装槽，方便第二限位件41和第二弹性件42起到限制第二转轴21与第二端52相对转动的作用。
其中，第二转轴21的周面包括相连接的第二弧面段211和第二平面段212，第二止位结构配置为第二平面段212，第二限位件41的靠近第二转轴21的端面配置为第二限位平面411；于第一运动状态，第二限位平面411与第二平面段212抵接，于第二运动状态，第二限位平面411与第二弧面段211抵接。可以理解的，于第一运动状态，第二限位件41在第二弹性件42的作用下，通过第二限位平面411始终与第二平面段212的平面配合，确保在第一运动状态时第二转轴21始终与第二端52相对静止而成为一整体，避免影响第一端51与车门安装座10的相对转动，使车门能够进行小角度开启。
第二弧面段211和第二平面段212相连，即第二弧面段211靠近第二限位平面411的距离小于第二平面段212靠近第二限位平面411的距离，以由第一运动状态切换至第二运动状态时，第二限位平面411在第二弹性件42的作用下，远离第二平面段212，并由与第二平面段212的平面配合切换至与第二弧面段211的滚动抵接，通过第二限位平面411始终与第二弧面段211滚动抵接，有利于弯臂50与第二转轴21的平稳转动，便于车门的大角度开启。
具体地，沿垂直于第二转轴21的轴线方向凹设有第二避让槽，第二避让槽的槽底壁可为所述第二平面段212。
更进一步地，如图1、图3、图4和图6所示，在一实施例中，第一弹性件32和第二弹性件42为同一弹性件，弯臂50内设有沿弯臂50长度方向延伸的安装腔53，第一限位件31和第二限位件41设于安装腔53内，且相面对的两表面通过同一弹性件相连接。如此能够使第一限位件31和第二限位件41产生联动，进而有效保障第一端51和第二端52转动的先后顺序，同时能够提升车门开启的顺畅性。此外，还能够减少零部件数量。
具体地，弯臂50包括上底板、下底板和连接于上底板和下底板之间的两侧板，上底板、下底板和两侧板共同围合形成两端开口的用以收容第一限位结构30和第二限位结构40的安装腔53，其中，第一弹性件32和第二弹性件42为同一弹性件，例如，采用限位弹簧，此时限位弹簧沿弯臂50的弯曲方向弯曲设置，且一端连接第一限位件31，另一端连接第二限位件41，进而当于第一运动状态时，限位弹簧同时施加力至第一限位件31和第二限位件41，以使第一限位件31与第一转轴11的第一弧面段111滚动抵接配合，第二限位件41与第二转轴21的第二平面段212平面抵接配合，当第一限位件31由与第一弧面段111滚动抵接切换至与第一转轴11的第一平面段112平面抵接配合时，由于第一限位件31与第一平面段112之间的距离变大，在限位弹簧的作用下，第一限位件31朝向第一平面段112运动，且通过第一限位平面311与第一平面段112抵接，此时，第一端51与第一转轴11相对静止，第二限位件41在限位弹簧的反向作用下，作用于第二平面段212的力变小，通过持续施加力至车门，第二限位件41能够由与第二平面段212平面抵接切换至与第二弧面段211滚动抵接，从而实现车门的顺畅开启，并且满足客户的大角度开启需求。
参照图1至6，在一实施例中，第二端52沿其垂直方向的两相对侧均设有限位台阶54，车身安装座20包括平行设置的两限位板22和连接两限位板22的连接板23，两限位板22和连接板23围合成侧向开口的收容腔24，限位板22可与限位台阶54相互卡接。如此设置，当车门进行关闭时，通过限位台阶54和限位部的卡接配合，限制弯臂50相对于车身安装座20的旋转范围，同时，部分弯臂50能够经由开口伸入收容腔24内，使得车门联动铰链机构整体结构更为紧凑，减少装配空间。
在一实施例中，第一端51沿其垂直方向的两相对侧均设有避让台阶56，避让台阶56用以限制弯臂50相对于车门安装座10的旋转范围；此外，还能够使车门联动铰链机构整体结构更为紧凑，减少装配空间。
参照图1和图4，在一实施例中，车门联动铰链机构还包括连接部60，连接部60一端与弯臂50固定连接，另一端通过电动限位器与车门固定连接。如此设置，能够采用电动方式使车门小角度开启，并满足车门悬停要求，进而增强使用舒适性和使用便利性。因此车门联动铰链机构可应用于手动门和电动门，满足客户的配置需求，使客户具有较好的使用体验感。
具体地，采用电动限位器为弯臂50的转动提供驱动力，即通过给予电动限位器开关门动作信号，进而推动车门通过第一转轴11绕第一端51旋转，实现车门的开启和关闭。其中，电动限位器内设有阻尼结构，便于车门平稳悬停至某一开度，防止因车门自身重量、停放位置等因素而相对车身自运动。当然于其他实施例中，电动限位器可替换为电动撑杆。
连接部60连接于弯臂50的下底板，且与弯臂50为一体结构，即下底板和连接部60可采用一体成型的工艺制造，或者通过焊接等方式进行固定。
于第一运动状态，弯臂50的第二端52与车身相对静止，此时，电动限位器通过连接部60一端固定在弯臂50，另一端可推动车门相对于弯臂50的第一端51转动；于第二运动状态，弯臂50的第一端51与车门相对静止，且电动限位器也与车门限度静止，此时，持续施加力至车门，可以通过车门安装座10、电动限位器和第一端51的相对固定而整体绕车身转动，有利于提升车门转动的可靠性。
由于在第二运动状态时，车门、车门安装座10、车门限位器和第一端51相对静止而成为一整体，因而在第二端52与车身安装座20相对转动的过程中，电动限位器无法起到阻尼作用，参照图4和图6，在一实施例中，第二端52与车身安装座20之间设有阻尼结构，以限制弯臂50与车身安装座20之间自发生相对运动，如此设置，有利于弯臂50在第二运动状态时，通过阻尼结构，使得车门能够平稳悬停至某一开度，防止因车门自身重量、停放位置等因素而相对车身自运动。
具体地，在一实施例中，第二端52远离第一端51的端部设有阻尼齿55，车身安装座20设有与阻尼齿55相匹配的凹槽结构25，如此能够通过增大摩擦阻力，在车门转动至一定开度时，通过第二端52上的阻尼齿55与车身安装座20上的凹槽结构25充分啮合，使得车门平稳悬停，从而提升车门的开关的使用可靠性和使用安全性。
本申请还提出一种车辆，该车辆包括车门联动铰链机构，该车门联动铰链机构的具体结构参照上述实施例，由于本车辆采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，车辆包括车身和车门，车门联动铰链机构连接于车身和车门之间，以实现车门的开启和关闭。
车门联动铰链机构内通过设置第一转轴11与弯臂50的第一端51转动连接，第二转轴21与弯臂50的第二端52转动连接，使得弯臂50具有第一运动状态和第二运动状态，进而使得车门的开度能够达到160°，满足客户的大角度开启需求，进而使得车门联动铰链机构能够应用于不同车型，例如家用、商用、露营等各种模式的车辆，开发成本低，应用广泛。
进一步地，通过设置电动限位器与弯臂50上的连接部60相连，使得车门能够采用电动模式进行车门的开启，满足客户的配置需求以及使客户具有较好的使用体验感；同时，于第一运动状态时，为车门的悬停提供支持力，提升车门开启的可靠性。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
