工程车辆通常对其驾驶室的视野及内部活动空间有较高要求。以平地机为例，平地机是一种用于平整路面的工程车辆，在工作过程中，位于驾驶室内的操作者需要一边控制铲刀作业装置作业，一边仔细观察作业后的路面状况，因此，驾驶室视野(包括铲刀作业装置视野、前方行进视野以及后方视野等)和驾驶室内操作者头部活动空间，已成为影响平地机的作业效率及作业安全性的重要因素。
然而，现有的驾驶室，通常为六立柱结构，且驾驶室内部的上下尺寸基本一致，存在立柱和底板遮挡驾驶室视野以及内部操作者头部活动空间不足等问题，导致作业效率较低，作业安全性较差。

图1-9示出了本公开一实施例驾驶室和驾驶室框架的结构示意图。
参照图1-9，本公开所提供的驾驶室框架10，包括支撑骨架1，支撑骨架1包括底架11、顶架12和支撑于底架11和顶架12之间的四立柱结构13，四立柱结构13包括两个前立柱131和两个后立柱132，且驾驶室框架10的内部尺寸沿由下至上的方向变大。
在本公开中，驾驶室框架10被设置为上大下小的四立柱框架结构，一方面，由于相对于上下尺寸一致的现有框架结构，可以在减小底板尺寸的前提下，不影响，甚至增大驾驶室内的上部空间，因此，不仅可以减少底板前部对铲刀作业装置的遮挡，还可以为操作者提供充足的头部活动空间，另一方面，由于相对于现有的六立柱框架结构，立柱数量减少，立柱布置位置更加灵活，因此，也有利于减少立柱对驾驶室视野的遮挡。
可见，本公开可以减少底板和立柱对视野的遮挡，并为操作者头部提供充足的活动空间，从而有效扩大驾驶室视野，并改善驾驶舒适性，使得平地机等工程车辆能够更高效并更安全地作业。
除了包括支撑骨架1，本公开的驾驶室框架10可以还包括外包于支撑骨架1的外蒙皮2。外蒙皮2可以增加驾驶室框架10的美观性。
作为使驾驶室框架10的内部尺寸沿由下至上的方向逐渐变大的一种实施方式， 在本公开中，外蒙皮2的外包于顶架12的顶蒙皮部21，可以设置为具有大于底架11尺寸的尺寸。其中，既可以顶蒙皮部21和顶架12的尺寸均大于底架11的尺寸，也可以顶蒙皮部21的尺寸大于底架11的尺寸，而顶架12的尺寸仍大致等于底架11的尺寸。可见，基于该实施方式，即使不改变顶架12的现有结构，即，即使顶架12和底架11的尺寸仍基本一致，也仍然能够使得驾驶室框架10具有上大下小的内部空间，因此，有利于简化改进成本，降低改进难度。
而作为使驾驶室框架10的内部尺寸沿由下至上的方向逐渐变大的另一种实施方式，在本公开中，外蒙皮2的外包于支撑骨架1后部的后蒙皮部22，可以设置为至少下部沿着由下至上的方向向后倾斜，换句话说，至少下部沿着由上至下的方向向前倾斜。其中，后蒙皮部22可以整体均沿着由下至上的方向向后倾斜，或者，也可以仅下部沿着由下至上的方向向后倾斜，而上部则仍保持大致竖直。在这种情况下，支撑骨架1本身也仍然可以保持上下尺寸一致的现有结构形式，而利用由下至上向后倾斜的后蒙皮部22来逐步增大驾驶室框架10由下至上的内部空间，同样有利于简化改进成本，降低改进难度。同时，由于后蒙皮部22的下部不再竖直，而是由上至下逐渐向前倾斜，形成对驾驶室后方机罩的避让，因此，还可以减少驾驶室100与机罩的干涉，从而更便于整机结构的布置。
可见，通过改进外蒙皮2的结构，来使现驾驶室框架10具有上大下小的内部空间，有利于减少对支撑骨架1现有结构的改变，节约改进成本，降低改进难度。
现有六立柱结构的驾驶室框架，其前立柱通常设置在六边形底架的前部顶点上，前立柱位置靠前，并且两个前立柱间的距离较小，对铲刀作业装置及操作者正前方行进视野的遮挡均较多，影响作业效率和作业及行进安全性。为了进一步解决该技术问题，在本公开中，前立柱131可以不再设置于底架11的前端部，而是设置于底架11的前后两端之间，且进一步地可以设置于六边形底架11的中部顶点处，这样前立柱131的位置较为靠后，且两个前立柱131之间的间距较大，可以减少前立柱131对驾驶室正前方视野的遮挡，且可以进一步减少前立柱131对铲刀作业装置等作业装置的遮挡，从而能够更有效地扩大作业装置视野及正前方行进视野，进而提高工程车辆的作业效率，改善作业及行驶安全性。
另外，现有技术中，驾驶室的前玻璃通常为非落地的，可视面积较小，这也限制了驾驶室的视野。因此，为了避免该问题，本公开的驾驶室框架10，其位于两个前立柱131前方的前玻璃安装部14可以在高度方向上由顶架12延伸至底架11。由于在这 种情况下，驾驶室100可以具有落地的前玻璃，可视面积较大，因此，可以进一步扩大驾驶室的视野。
其中，既可以将驾驶室框架10的位于两个前立柱131前方的空间的部分设置为前玻璃安装部14，也可以将驾驶室框架10的位于两个前立柱131前方的空间整体设置为前玻璃安装部14，后者前玻璃的面积更大，视野更宽，且可以使得前玻璃不仅包括正前玻璃，还同时包括左前玻璃和右前玻璃，便于驾驶人员从前、左和右等不同角度进行观察。
并且，在本公开中，前玻璃安装部14可以进一步设置为沿着由下至上的方向逐渐向外倾斜，这样可以使得驾驶室内的上部尺寸更加大于下部尺寸，方便操作者头部更加灵活地活动，同时，也使得前玻璃对位于驾驶室前方的铲刀等作业装置形成避让，方便铲刀等作业装置和驾驶室的布置。
下面结合图1-9所示的实施例来对本公开予以进一步地说明。该实施例以平地机的驾驶室为例。
如图1-5所示，在该实施例中，驾驶室100包括驾驶室框架10、前玻璃3、门4、后玻璃5、外饰结构和内饰结构7等，其中，前玻璃3、门4和后玻璃5分别设置在驾驶室框架10的前玻璃安装部14、门安装部15和后玻璃安装部上；外饰结构设置在驾驶室框架10的外部，包括后视镜、报警灯、顶棚62、以及具有雨刷61的雨刷结构等；内饰结构7则设置在驾驶室框架10的内部。
如图5-9所示，在该实施例中，驾驶室框架10包括支撑骨架1和外蒙皮2，外蒙皮2包裹于支撑骨架1外部，与支撑骨架1一起限定形成驾驶室框架10的内部空间。
由图7和图8可知，该实施例的支撑骨架1包括底架11、顶架12和四立柱结构13，底架11和顶架12上下间隔地相对设置，四立柱结构13则支撑于底架11和顶架12之间，并包括两个前立柱131和两个后立柱132。
其中，底架11和顶架12均呈六边形，该六边形包括前后依次相连的梯形和矩形，且位于前部的梯形沿着由后至前的方向逐渐收窄，即，梯形的短边位于长边的前方。并且，底架11和顶架12的梯形的短边大致平行；顶架12和底架11的后边缘大致平齐。基于此，底架11和顶架12均具有两个前部顶点、两个中部顶点和两个后部顶点，且两个前部顶点间的间距较窄，两个中部顶点间的间距和两个后部顶点间的间距大致相等并均较宽。
如图8所示，在该实施例中，底架11呈中部镂空结构，即，底架11的中部并未 设置底板，底板位于整机机架上。驾驶室100安装后，底板嵌合于底架11的镂空部分中。
顶架12包括沿前后方向依次布置并彼此连接的第一顶架121和第二顶架122，第一顶架121呈梯形，第二顶架122呈矩形。且如图8所示，第二顶架122与两个后立柱132连接(例如焊接)为一体，形成后部两立柱防翻滚结构，用于防翻滚和防落物。第二顶架122的各边所对应的柱体较第一顶架121的各边所对应的柱体粗壮。
结合图7和图8可知，在该实施例中，两个前立柱131位于底架11的两个中部顶点上，两个后立柱132位于底架11的两个后部顶点上。
两个前立柱131被设置在底架11的两个中部顶点上，相对于设置在底架11的两个前部顶点上的情况，两个前立柱131的位置靠后，且两个前立柱131间的间距变大，因此，可以有效减少两个前立柱131对铲刀作业装置视野和前方行进视野的遮挡，并且，还有利于增大固定于前立柱131前方的前玻璃3的面积(这一点将在下方结合前玻璃安装部14及前玻璃3的设置予以进一步说明)，这也可以进一步改善驾驶室100的视野。
可见，该实施例两个前立柱131的设置位置，能够有效改善驾驶室视野。
另外，如图7和图8所示，在该实施例中，前立柱131比后立柱132细。这样，一方面，前立柱131较细，可以进一步减少前立柱131对驾驶室视野的遮挡；另一方面，后立柱132较粗，能够增强驾驶室框架10的结构稳定性，更好地与第二顶架122一起起到防翻滚和防落物的作用。可见，该设置可以在保证驾驶室结构稳定性的基础上，起到优化驾驶室视野的作用。
结合图1-7可知，在该实施例中，驾驶室框架100的位于前立柱131前方并位于顶架121(具体为第一顶架121)和底架11之间的空间整体被设置为前玻璃安装部14。这使得前玻璃安装部14不仅包括正前玻璃安装部141，还同时包括左前玻璃安装部142和右前玻璃安装部143，其中，正前玻璃安装部141位于底架11的两个前部顶点之间，左前玻璃安装部142和右前玻璃安装部143分别位于正前玻璃安装部141的左右两侧，并均位于对应侧的前立柱131和底架11的前部顶点之间，并且，正前玻璃安装部141、左前玻璃安装部142和右前玻璃安装部143均在高度方向上由顶架12延伸至底架11。这也就使得前玻璃3不仅包括安装于正前玻璃安装部141上的正前玻璃31，还包括安装于左前玻璃安装部142上的左前玻璃32和安装于右前玻璃安装部143的右前玻璃33，且正前玻璃31、左前玻璃32和右前玻璃33均为落地玻璃。
将前玻璃3设置为同时包括正前玻璃31和位于正前玻璃31左右两侧的左前玻璃32和右前玻璃33，相对于前玻璃3只包括正前玻璃31的情况，可以在左右方向上有效增大前玻璃3的面积，使得驾驶员不仅能从正前方观察驾驶室外部情况，还能从左前方和右前方观察驾驶室外部情况，方便驾驶员根据不同工况实施多角度的观察，获得更加清晰准确的观察结果。
并且，将前玻璃3整体设置为落地玻璃，又使得前玻璃3的面积沿高度方向进一步增大，方便驾驶员更充分地观察铲刀作业装置及周边环境，更安全地驾驶及作业。
可见，该实施例前玻璃安装部14的设置方式，使得驾驶室100具有更大面积的前玻璃3，铲刀作业装置视野和前方行进视野等驾驶室视野更加开阔，驾驶及作业的效率和安全性更高。
并且，由图3可知，在该实施例中，顶架12的梯形短边短于底架11的梯形短边，这使得，沿着由下至上的方向，正前玻璃安装部141的宽度逐渐减小，左前玻璃安装部142和右前玻璃安装部143的宽度逐渐增大，也即使得，正前玻璃31的宽度逐渐减小，左前玻璃32和右前玻璃33的宽度逐渐增大。该设置中三块前玻璃沿上下方向的宽窄变化趋势，更符合驾驶员对正前方、左前方和右前方三个不同视角的观察需求，相对于由下至上正前玻璃变宽和左前玻璃及右前玻璃变窄的设置方式，可以在相同玻璃面积的情况下获得更多有用的观察视野和头部活动空间。
图1-5示出的前玻璃3采用三块平面玻璃，更容易适应正前玻璃安装部141、左前玻璃安装部142和右前玻璃安装部142之间呈角度的位置关系，加工简单，成本较低，但在本公开的其他实施例中，前玻璃3也可以采用曲面(例如弧面)玻璃，此时可以采用一整块玻璃来替代图示实施例的三块玻璃。
如图5和图6，在该实施例中，驾驶室框架10的门安装部15包括左门安装部和右门安装部，左门安装部位于同处于左侧的前立柱131和后立柱132之间，右门安装部位于同处于右侧的前立柱131和后立柱132之间；相应地，驾驶室100包括两个门4，一个门4安装于左门安装部，用作左门，另一个门4安装于右门安装部，用作右门。其中，左门铰接于左前立柱上，右门铰接于右前立柱上，使得如图1所示，左门和右门均向前开启。
通过在左侧两侧均设置安装门4的门安装部，使得该实施例的驾驶室100可以满足左右都能上下车的需求，从而相对于只有一侧设门的情况，驾驶员上下车更加方便灵活，尤其当其中一侧因存在障碍或危险而无法打开车门时，驾驶员可以选择从另一 侧下车，适应工况更多，使用安全性也更高。
而与门向后开的情况相比，该实施例将门设置为向前开的，还可以防止门4开启时与机罩发生干涉，开关门也更加方便自如。
并且，门4上部设有推拉窗，可以方便通风换气，改善驾驶室内部的空气质量，同时，也可以进一步方便驾驶员，尤其在上下车时，观察外部情况。
另外，如图1和图6所示，在该实施例中，驾驶室框架10的内部尺寸由下至上逐渐增大，使得驾驶室100的内部空间整体上呈上大下小的倒塔形结构，这样不仅可以减少驾驶室底板对铲刀作业装置的遮挡，还可以增加驾驶员上半身的活动空间，方便驾驶员活动头部或者向外探身，改善驾驶舒适性。
其中，为了使驾驶室框架10的内部尺寸由下至上逐渐增大，该实施例对支撑骨架1和外蒙皮2均做了一些改进。
一方面，如图1和图4所示，在该实施例中，前玻璃安装部14并非竖直设置的，而是与竖直方向存在夹角。具体地，该实施例的前玻璃安装部14沿着由下至上的方向逐渐向外倾斜，即，安装于前玻璃安装部14的前玻璃3也沿着由下至上的方向逐渐向外倾斜。其中，前玻璃安装部14沿着由下至上的方向逐渐向外倾斜，可以通过使顶架12的前边缘较底架11的前边缘靠前来实现。基于此，驾驶室100内部空间的前部由下至上逐渐变大。
另一方面，在该实施例中，如图6和图9所示，外蒙皮2的顶蒙皮部21的后边缘较顶架12的后边缘靠后，且外蒙皮2的后蒙皮部22的上部竖直而下部沿着由下至上的方向向后倾斜。其中，不同于顶架12采用六边形形状，该实施例的顶蒙皮部21采用八边形形状，该八边形包括位于前部由后向前收窄的梯形、位于中部的矩形和位于后部由前向后收窄的梯形。
由于顶架12的后边缘与底架11的后边缘沿前后方向大致平齐，因此，顶蒙皮部21的后边缘较顶架12的后边缘靠后，也就使得顶蒙皮部21的后边缘较底架11的后边缘靠后，从而使得外蒙皮2不再贴合于支撑骨架1上，而是后部向后凸出于支撑骨架1的后部，即，后蒙皮部22与后立柱132之间沿前后方向存在空隙，这样相对于后蒙皮部22贴合于后立柱132上的情况，可以增大驾驶室框架10的内部空间，使驾驶室100内部更加宽敞，方便内部结构部件的布置，也方便驾驶员活动。
而进一步地，后蒙皮部22的上部竖直而下部沿着由下至上的方向向后倾斜，则使得驾驶室100内部空间的后部也是上大下小的。
可见，基于对支撑骨架1和外蒙皮2所做的上述改进，从向前和向后两个方向上，均由下至上加大驾驶室框架100的内部空间，使得驾驶室100可以同时具有较小的下部尺寸和较大的上部尺寸，一方面能够减少底板对视野的遮挡，另一方面还能够为操作者头部提供充足的活动空间，满足在不同工况下驾驶员探头观察外部情况或舒展头部的需求，实现更舒适的操作过程。同时，后蒙皮部22的下部沿着由下至上的方向向后倾斜，还可以形成对驾驶室后方机罩的避让，减少驾驶室100与机罩的干涉。
并且，如图2所示，该实施例的后蒙皮部22(具体为后蒙皮部22的竖直设置的上部部分)上设有后玻璃安装部，后玻璃5安装于后玻璃安装部上。由于后蒙皮部22向后凸出于支撑骨架1的后部，因此，安装于后蒙皮部22上的后玻璃5也向后凸出于支撑骨架1的后部，这可以进一步增大驾驶室100的后部视野，方便驾驶员观察驾驶室100的后部情况。
而如图4所示，在该实施例中，门4的靠近后蒙皮部22的一侧的下部与后蒙皮部22的下部大致平行，也由下至上逐渐向后倾斜，这使得整体结构较为美观。
另外，如图1-5所示，在该实施例中，雨刷结构包括6个雨刷，其中5个雨刷61设置在前玻璃3上，其余1个雨刷61设置在后玻璃5上，且其中，左前玻璃32和右前玻璃33上均设有2个雨刷61，且位于左前玻璃32和右前玻璃33上的两个雨刷61沿上下方向布置，一个位于上部，另一个位于中部。基于该设置，即使在雨天，也能为驾驶员提供良好的视野条件，提高雨天行驶及作业的安全性。
综合上述对图1-9所示实施例的描述可知，该实施例的驾驶室100，铲刀作业装置视野和前方行进视野等驾驶室视野均较为开阔，且内部空间布局合理，操作者头部活动空间充裕，操作舒适性较高，有利于提高平地机的作业效率及作业安全性。
以上所述仅为本公开的示例性实施例，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
