[0003] 驻车空调是指卡车等重型车辆在停驶状态下使用的空调， 与原车空调系统彼此独立。 驻车空调通常采用电驱动， 能耗低， 制冷 成本低， 且更环保， 已逐渐成为了卡车市场的刚需产品。 现有的驻车 空调系统包括内机和外机， 内机安装在驾驶室的室内顶棚或后壁上， 外机安装在室外顶棚上， 为了保证外机的安装稳定性， 外机的出风口 通常朝向上方， 罩设在风扇上方的外机风罩通常设置为直壁结构。 由 于空调外机常年暴露在室外， 在行车或驻车过程中， 高处掉落的树枝、 树叶、 碎石等杂物会经由风罩的出风口进入空调内部， 影响风扇正常 运转， 缩短空调使用寿命， 甚至破坏电路， 造成安全隐患。
[0004] 相应地， 本领域需要一种新的驻车空调用外机风罩来解决 上述问题。 发明内容

[0030] 基于背景技术指出的现有驻车空调外机易被异物侵入的问 题， 本发明提供了一种驻车空调用外机风罩及驻车空调， 旨在阻挡异物 落入外机内部， 避免异物对外机风扇等部件造成损坏， 同时提高风扇的 出风效果。
[0031] 参照图 1-图 3， 图 1为本发明的驻车空调用外机风罩的俯 视示意图， 其中示出了防护主体的一种实施方式； 图 2 为本发明的驻 车空调用外机风罩的仰视示意图； 图 3 为本发明的驻车空调用外机风 罩的等轴测视图。
[0032] 如图 1-图 3中所示，本实施例中的驻车空调用外机风罩包括 风罩主体 1， 风罩主体 1连接到外机的壳体上。 风罩主体 1上形成有出风 口 4， 方便实现风扇排风。 参照图 3， 风罩主体 1的中部向上延伸形成筒 状围壁 2, 出风口 4形成在筒状围壁 2的顶端。出风口 4处设置有格栅 3 , 格栅 3 在不妨碍出风的同时， 能够防止风罩外体积较大的杂物进入风罩 中。格栅 3的上方设置有防护构件 5 , 防护构件 5设置成其沿垂直方向的 投影至少能够覆盖格栅 3。 具体地， 在使用状态下， 为保证外机的安装稳 定性， 外机风罩的出风口 4通常竖直向上安装， 防护构件 5设置成沿垂 直方向的投影至少能够覆盖格栅 3 , 这样在行车过程中， 当位于风罩上方 的树叶、 树枝等坠物落向外机时， 首先会被防护构件 5 阻挡， 从而无法 通过格栅 3处的出风口 4落入风罩内部， 避免了杂物对内部风扇等部件 的正常运转造成阻碍， 从而延长外机的使用寿命。
[0033] 本发明提供的驻车空调用外机风罩，通过将风罩主体 1的中 部向上延伸形成筒状围壁 2, 将外机风扇设置在筒状围壁 2内， 能够有效 引导风扇出风，提高外机出风效率；再者，通过在出风口 4处设置格栅 3 , 在格栅 3上方设置防护构件 5， 防护构件 5与格栅 3之间形成一定间距， 并且防护构件 5沿垂直方向的投影可以覆盖格栅 3 , 当树枝、 树叶、 石子 等杂物向格栅 3掉落时， 会被防护构件 5阻挡， 从而无法进入风机， 这 样， 防护构件 5 的设置在不影响风扇出风的情况下， 有效防止了异物的 入侵， 避免了对外机内部结构造成损害。
[0034] 参照图 3， 本实施例中的外机风罩的风罩主体 1为方形， 风 罩主体 1 的边沿向下折弯形成罩壳结构， 风罩主体 1上设置有能够与外 机壳体连接的连接结构， 如设置有紧固件安装孔、 卡钩等结构。 风罩主 体 1设置有台阶状空腔， 以容置内部的部件， 使风罩结构更紧凑。
[0035] 在一些优选的实施例中， 防护构件 5包括防护主体 50和支 撑主体 51， 支撑主体 51夹设到格栅 3与防护主体 50之间， 以使防护主 体 50能够罩设在格栅 3上方。 防护主体 50主要起到阻挡坠物的作用， 因此防护主体 50至少应该具有致密表面。 优选地， 防护主体 50为平板 状， 其形状可以为任意形状， 只要保证其沿垂直方向的投影至少能够覆 盖格栅 3即可， 例如可以采用方形板、 圆板、 多边形板等结构。
[0036] 进一步地， 防护主体 50为圆形平板状。 圆形平板状的防护 主体 50可以设置成与筒状围壁 2适配的结构， 既能有效阻挡异物， 还可 以保证外机风罩整体的美观性。 更进一步地， 该圆形平板状的防护主体 50 的中部还可以设置通孔并因此形成圆环形平板状结构。 具体地， 参照 图 1所示， 本实施例中的防护构件 5采用 4块扇形平板拼接形成防护主 体 50， 由于筒状围壁 2用于容置风扇， 风扇转动过程中， 转轴部位是不 出风的， 因此在设计格栅 3时， 可以在格栅 3中部设置中部挡板 33用于 保护风扇的转轴部位， 此时可以在形成防护主体 50的圆形平板中间设置 通孔， 通孔的直径可以略小于中部挡板 33 的直径， 或者与中部挡板 33 的直径适配， 这样既能起到阻挡杂物的作用， 还可以节省制作防护主体 50的材料， 减轻风罩的重量。 当防护主体 50采用板状结构时， 既能有效 阻挡坠物， 还能起到挡雨的效果， 在防止杂物侵入的同时， 降低雨水对 外机内部部件的侵害。
[0037] 本领域技术人员可以理解的是，虽然本实施例中的防护主体 50 的结构是以多个扇形平板拼接形成的环形板状结构为例进行描述的， 但这并不是限制性的， 可以理解的是， 分成的扇形平板的数量是可依据 需要进行选择的， 平板结构可以为一体结构， 或者通过两个、 三个、 四 个甚至更多的扇形平板拼接形成。
[0038] 替代性地， 防护主体 50可以采用非常致密的网状结构， 例 如采用非常致密的钢丝网， 钢丝网能够有效阻挡比网孔大的坠物， 如树 叶、 树枝、 碎石等物， 起到较好的防护效果。
[0039] 替代性地， 防护主体 50可以设置为锥状结构， ， 这样既能 够阻挡杂物， 还可以对雨水形成导流作用， 使得落下的雨水可以依靠重 力作用排向筒状围壁 2的外侧， 增强风罩的防护作用。
[0040] 参照图 1-图 3所示， 本发明中的格栅 3由主支撑辐板 30、 辅助支撑辐板 31和栅板 32组成， 主支撑辐板 30的结构强度较辅助支撑 辐板 31的结构强度高， 用于形成格栅 3的主要框架， 以及用于支撑中部 挡板 33。 主支撑辐板 30沿筒状围壁 2的径向辐射， 均匀地排布在出风口 4处， 主支撑辐板 30之间均匀地布置一条或多条辅助支撑辐板 31， 沿筒 状围壁 2的周向上均匀排布有栅板 32,栅板 32沿筒状围壁 2的周向延伸。 栅板 32与主支撑辐板 30和辅助支撑辐板 31连接， 并共同构造出较为致 密的格栅 3。 优选地， 栅板 32倾斜设置， 以其中一个栅板 32为例， 其所 在的曲面形成为正锥面或倒锥面， 当然还可以以其他方式倾斜设置， 以 使相邻的栅板 32在水平面上的投影彼此重叠， 这样能进一步减小杂物落 入的几率。
[0041 ] 可以理解的是，以上格栅 3的结构仅为本发明的格栅 3的一 种实施方式， 本领域技术人员可以对格栅 3中主支撑辐板 30、 辅助支撑 辐板 31和栅板 32的结构作出适应性调整， 例如辅助支撑辐板 31可以与 径向偏移一定角度， 表面可以为平面或者为弧面； 栅板 32可以绕中轴线 螺旋设置， 可以连续设置， 也可以设置为分段结构； 在辅助支撑辐板 31 的强度足够大的情况下， 可以取消主支撑辐板 30等等， 以上已表述或未 表述的格栅 3结构， 均应在本发明的保护范围之内。
[0042] 支撑主体 51用于将防护主体 50支撑在格栅 3上方，以使格 栅 3与防护主体 50之间形成一定的间距， 使得防护主体 50既不妨碍出
风口 4出风， 还能在格栅 3上方形成一定范围的遮蔽。 支撑主体 51的设 置方式有多种。 参照图 3所示， 本实施例中， 支撑主体 51夹设到格栅 3 与防护主体 50之间。 具体地， 支撑主体 51形成为立板结构， 该立板结 构的下部连接到主支撑辐板 30上， 上部连接到平板状的防护主体 50上， 以使防护主体 50能够悬置在格栅 3上方， 对出风口 4形成遮蔽。 进一步 地， 该立板结构与防护主体 50可以通过可拆卸连接的方式连接， 也可以 制成为一体结构。 以可拆卸方式连接时， 可以方便地对防护主体 50进行 拆解和替换。 立板结构的下部可以与格栅 3 以可拆卸的方式连接， 也可 以制成为一体结构。
[0043] 替代性地， 还可以将支撑主体 51连接到筒状围壁 2与防护 主体 50之间。 具体地， 支撑主体 51形成为立柱结构或具有弧形表面的 板结构， 弧形表面与筒状围壁 2 的外周面适配。 以立柱结构为例， 该立 柱结构的下部连接到筒状围壁 2 的外侧面上， 例如通过焊接、 粘接等方 式连接； 立柱结构的上部连接到平板状的防护主体 50的下表面上， 形成 悬臂连接状， 此时需要保证立柱的强度足够大， 以使防护主体 50能够稳 定悬置在格栅 3上方， 对出风口 4形成遮蔽。 进一步地， 该立柱结构与 防护主体 50可以通过可拆卸连接的方式连接， 也可以制成为一体结构。 以可拆卸方式连接时， 可以方便地对防护主体 50进行拆解和替换。 立柱 结构的下部可以与格栅 3以可拆卸的方式连接， 也可以制成为一体结构。
[0044] 本发明的另一个实施例中， 提供了一种驻车空调， 该驻车空 调包括外机和内机。 外机包括外机风罩、 壳体， 在壳体内设置有风扇、 压缩机、 换热器等部件。 其中外机风罩为前述的外机风罩。 可以理解的 是， 由于该驻车空调配置有前述的外机风罩， 因此具备前述的外机风罩 的所有技术效果， 在此不再赘述。
[0045] 至此， 已经结合附图所示的优选实施方式描述了本发明的 技术方案， 但是， 本领域技术人员容易理解的是， 本发明的保护范围 显然不局限于这些具体实施方式。 在不偏离本发明的原理的前提下， 本领域技术人员可以对相关技术特征作出等同的更改或替换， 这些更 改或替换之后的技术方案都将落入本发明的保护范围之内。
