[0041] 此外， 术语"第一"、 "第二 "仅用于描述目的， 而不能理解为指示或暗示相对重 要性或者隐含指明所指示的技术特征的数量。 由此， 限定有 "第一"、 "第二 "的特 征可以明示或者隐含地包括一个或者更多个该特征。 在本发明的描述中， "多个" 的含义是两个或两个以上， 除非另有明确具体的限定。
[0042] 在本发明中， 除非另有明确的规定和限定， 术语"安装"、 "相连"、 "连接"、 "固 定"等术语应做广义理解， 例如， 可以是固定连接， 也可以是可拆卸连接， 或成 一体； 可以是机械连接， 也可以是电连接； 可以是直接相连， 也可以通过中间 媒介间接相连， 可以是两个元件内部的连通或两个元件的相互作用关系。 对于 本领域的普通技术人员而言， 可以根据具体情况理解上述术语在本发明中的具 体含义。
[0043] 如图 1至图 6所示， 本发明实施例提供的一种汽车头灯驱动装置， 包括外壳 10、 PCB组件 20、 输入线 30和输出线 40， 所述 PCB组件 20设于所述外壳 10内， 所述输 入线 30和所述输出线 40均与所述 PCB组件 20电性连接并伸出至所述外壳 10外， 所 述外壳 10包括外侧板 11、 内侧板 12以及连接于所述外侧板 11宽度方向两端与所 述内侧板 12宽度方向两端之间的左侧板 13和右侧板 14， 所述外侧板 11、 所述内 侧板 12、 所述左侧板 13和所述右侧板 14共同围合形成供所述 PCB组件 20安装的安 装腔 15, 所述内侧板 12朝向所述安装腔 15凹设形成内弧形安装面 16和 /或所述外 侧板 11朝反向所述安装腔 15凸设形成外弧形安装面 17。 [0044] 具体地， 本发明实施例的汽车头灯驱动装置， 通过内侧板 12朝向安装腔 15凹设 形的内弧形安装面 16和 /或外侧板 11朝反向安装腔 15凸设形成外弧形安装面 17， 使得外弧形安装面 17与内弧形安装面 16的弧度朝向一致， 形成双弧度外形设计 , 那么将其安装于灯具内时， 如图 6所示， 外壳 10的内侧板 12和外侧板 11不会在 A处受到灯具壳体的干涉， 外壳 10可以顺利装入灯具壳体内的环形夹缝中， 实现 无损安装， 更加贴切实际安装需求， 更加灵活， 节省安装时间； 同吋， 内弧形 安装面 16和外弧形安装面 17的设计也分别使得内侧板 12和外侧板 11具有更大的 面积， 内侧板 12和外侧板 11与空气的接触面积更大， 使外壳 10在工作过程中产 生的热量更加快速地散失， 降低外壳 10在工作过程中的温度， 进而使得整个汽 车头灯驱动装置的使用寿命更长。
[0045] 更具体地， 本发明实施例提供的汽车头灯驱动装置， 主要应用在圆形汽车头灯 上， 当然， 还可以应用在船、 摩托等机动车以及其他场所的圆形灯具上。
[0046] 如图 4至图 5所示， 本实施例中， 所述内弧形安装面 16的弧度沿所述内侧板 12的 宽度方向布置。 具体地， 如此设计使得整个外壳 10在竖向放置吋， 内侧板 12的 内弧形安装面 16与灯具壳体内的夹缝的弧度适配， 那么可以以竖向方向将整个 汽车头灯驱动装置插入灯具壳体内的夹缝中， 如此， 更加容易对汽车头灯驱动 装置进行安装， 减少对汽车头灯驱动装置的安装吋间， 提升对汽车头灯驱动装 置的安装效率。
[0047] 如图 4至图 5所示， 本实施例中， 所述外弧形安装面 17的弧度沿所述外侧板 11的 宽度方向布置。 同理， 如此设计使得整个外壳 10在竖向放置时， 外侧板 11的外 弧形安装面 17与灯具壳体内的夹缝的弧度适配， 那么可以以竖向方向将整个汽 车头灯驱动装置插入灯具壳体内的夹缝中， 如此， 更加容易对汽车头灯驱动装 置进行安装， 减少对汽车头灯驱动装置的安装时间， 提升对汽车头灯驱动装置 的安装效率。
[0048] 即上述对内弧形安装面 16和外弧形安装面 17结构的限定可以进一步使得汽车头 灯驱动装置的安装更加简易， 实用性强。
[0049] 如图 4至图 5所示， 本实施例中， 所述外侧板 11朝反向所述安装腔 15凸设有多个 间隔并排的外侧散热齿 111， 各所述外侧散热齿 111的端面形成所述外弧形安装 面 17。 具体地， 外侧散热齿 111的设计增加了整个外壳 10的表面积， 使得外壳 10 与外界空气的接触面积进一步增加， 且多个外侧散热齿 111间隔并排设置可以使 得空气的对流速度更快， 加速将外壳 10上的热量散发到空气中， 同时也避免各 外侧散热齿 111之间相互叠加。 同时， 并排的多个外侧散热齿 111的外端面形成 外弧形安装面 17， 使得多个外侧散热齿 111的设置不会影响整个汽车头灯驱动装 置的安装。
[0050] 如图 4至图 5所示， 本实施例中， 各所述外侧散热齿 111的高度由所述外侧板 11 宽度方向的中部向所述外侧板 11宽度方向的两侧逐渐递减形成所述外弧形安装 面 17。 具体地， 也就是说， 位于外侧板 11宽度方向中部的外侧散热齿 111的高度 最高， 位置越靠近外侧板 11宽度方向的两侧的外侧散热齿 111的高度逐渐降低 , 这样即可使得多个外侧散热齿 111的外端面形成沿外侧板 11的宽度方向布置的外 弧形安装面 17, 结构设计非常巧妙， 既可以确保整个外壳 10的有效散热面积增 加， 同时也使得外壳 10的外形与灯具壳体内的夹缝形状适配， 确保安装的便利 性。
[0051] 如图 4至图 5所示， 本实施例中， 所述左侧板 13朝反向所述安装腔 15凸设有多个 间隔并排的左侧散热齿 131。 具体地， 多个左侧散热齿 131的设置在左侧板 13方 向增加了与空气接触的散热面积， 那么在外壳 10的左侧可以进一步加强对外壳 1 0热量的散失， 从而进一步提升外壳 10的散热效果。 需要说明的是， 该左侧散热 齿 131的作用与外侧散热齿 111的作用一样。
[0052] 如图 4至图 5所示， 本实施例中， 所述右侧板 14朝反向所述安装腔 15凸设有多个 间隔并排的右侧散热齿 141。 具体地， 多个右侧散热齿 141的设置在右侧板 14方 向增加了与空气接触的散热面积， 那么在外壳 10的右侧可以进一步加强对外壳 1 0热量的散失， 从而进一步提升外壳 10的散热效果。 需要说明的是， 该右侧散热 齿 141的作用与左侧散热齿 131和外侧散热齿 1 U的作用一样， 并与左侧散热齿 13 1和外侧散热齿 111结合为外壳 10全方位散热。
[0053] 本实施例中， 所述外侧板 11、 所述内侧板 12、 所述左侧板 13和所述右侧板 14采 用型材铝一体成型而制。 具体地， 釆用型材铝制作具有外侧板 11、 内侧板 12、 左侧板 13和右侧板 14的外壳 10可以使得外壳 10的整体尺寸更小， 并且还能够提 升外壳 10的导热效率。
[0054] 如图 1至图 3所示， 本实施例中， 所述汽车头灯驱动装置还包括分别用于封住所 述安装腔 15的前端和后端的前端盖 50和后端盖 60 , 所述前端盖 50设于所述外壳 1 0的前端并与所述外壳 10可拆卸连接， 所述后端盖 60设于所述外壳 10的后端并与 所述外壳 10可拆卸连接。 具体地， 前端盖 50和后端盖 60的设置封住了安装腔 15 的敞幵口， 这样可以设于安装腔 15内的 PCB组件 20起到保护的作用， 即防止外物 进入到安装腔 15内或者工作人员触碰到 PCB组件 20从而对 PCB组件 20造成破坏或 者影响 PCB组件 20的工作。 而将前端盖 50和后端盖 60与外壳 10的可拆卸连接可以 确保方便对前端盖 50和后端盖 60进行拆卸， 那么即可方便对设于安装腔 15内的 P CB组件 20进行维护或者更换。
[0055] 如图 1至图 5所示， 本实施例中， 所述左侧板 13的前端和所述右侧板 14的前端均 设有前安装孔 18 , 所述前端盖 50设有与所述前安装孔 18位置对应的前过孔 51并 通过前紧固件 80穿设所述前过孔 51与所述前安装孔 18锁紧连接。 具体地， 通过 前紧固件 80即可将前端盖 50锁紧在左侧板 13和右侧板 14上， 这样由于该前端盖 5 0同吋与左侧板 13和右侧板 14锁紧连接， 前端盖 50的两侧锁紧更加平衡， 那么使 得前端盖 50安装后的稳定性和可靠性更佳， 无需担心汽车头灯驱动装置在使用 吋该前端盖 50会脱落， 实用性强。
[0056] 如图 1至图 5所示， 本实施例中， 所述左侧板 13的后端和所述右侧板 14的后端均 设有后安装孔 19， 所述后端盖 60设有与所述后安装孔 19位置对应的后过孔 61并 通过后紧固件 90穿设所述后过孔 61与所述后安装孔 19锁紧连接。 具体地， 通过 后紧固件 90即可将后端盖 60锁紧在左侧板 13和右侧板 14上， 这样由于该后端盖 6 0同吋与左侧板 13和右侧板 14锁紧连接， 后端盖 60的两侧锁紧更加平衡， 那么使 得后端盖 60安装后的稳定性和可靠性更佳， 无需担心汽车头灯驱动装置在使用 吋该后端盖 60会脱落， 实用性强。
[0057] 进一步地， 前紧固件 80和后紧固件 90均可以釆用螺栓、 螺丝或者螺钉等。
[0058] 如图 1至图 3所示， 本实施例中， 所述前端盖 50的中部设有过线槽 52， 所述输入 线 30和所述输出线 40均穿过所述过线槽 52伸出至所述外壳 10外的同一侧。 具体 地， 将输入线 30和输出线 40设置在同一侧可以减小外壳 10的整体尺寸， 而且在 安装时， 不会外壳 10背向设置输入线 30和输出线 40的一端安装不会受到输入线 3 0或者输出线 40的干涉， 更加符合实际需求。
[0059] 如图 1至图 3所示， 本实施例中， 所述过线槽 52上嵌装有线档 70， 所述输入线 30 和所述输出线 40均穿设固定于所述线档 70上。 具体地， 线档 70的设置可以起到 在输入线 30和输出线 40穿入线槽的位置处固定输入线 30和输出线 40的作用， 这 样在使用过程中， 即使多次扭动或者缠绕输入线 30和输出线 40， 也无需担心输 入线 30和输出线 40穿入线槽的位置处出现断裂， 确保使用过程中输入线 30和输 出线 40不会轻易被损坏。
[0060] 如图 3所示， 本实施例中， 所述 PCB组件 20包括 PCB板 21和设于所述 PCB板 21上 的多个电子元件 22。 具体地， 电子元件 22作为工作部件， 而 PCB板 21则作为各电 子元件 22的电气连接的提供者， 那么 PCB板 21和各电子元件 22在工作过程中产生 的热量散发到安装腔 15内接触外壳 10的外侧板 11、 内侧板 12、 左侧板 13和右侧 板 14, 并经外侧板 11、 内侧板 12、 左侧板 13和右侧板 14以及设置在外侧板 11上 的外侧散热齿 111、 设置在左侧板 13的左侧散热齿 131和设置在右侧板 14的右侧 散热齿 141散失。
[0061] 如图 1至图 2和图 4至图 5所示， 本实施例中， 所述内侧板 12上设有用于与外界部 件固定连接的紧固孔 122。 具体地， 紧固孔 122优先设定两个， 且在内侧板 12的 内侧板 12的宽度方向的两侧， 这样即可通过其他辅助连接件与紧固孔 122锁紧连 接， 从而实现将外壳 10组装在外界部件上。
[0062] 如图 2和图 5所示， 本实施例中， 所述内侧板 12的外表面设有多个间隔并排的间 隔条 121。 具体地， 间隔条 121的设置使得内侧板 12与灯具壳体接触吋， 在内侧 板 12与灯具壳体之间形成间隔条 121高度的间距， 该间距可以空气流通， 同样可 以提升外壳 10的散热效率。
[0063] 综上所述可知本发明乃具有以上所述的优良特性， 得以令其在使用上， 增进以 往技术中所未有的效能而具有实用性， 成为一极具实用价值的产品。
[0064] 以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的 思想和原则之内所作的任何修改、 等同替换或改进等， 均应包含在本发明的保 护范围之内。
