具体实施方式detailed description
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。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。The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application.

申请概述Application overview
为了解决背景技术中存在的底盘固定架承重效果差,行走不平稳的技术问题,可以增大轮体的直径,能够改善底盘在行走过程中不平稳的现象。但是,由于轮体的安装受限于底盘的底部空间的大小,因此,通过增大轮体的直径方式,就受到了限制。In order to solve the technical problems of poor load-bearing effect of the chassis fixing frame and unstable walking in the background technology, the diameter of the wheel body can be increased to improve the unevenness of the chassis during walking. However, since the installation of the wheel body is limited by the size of the bottom space of the chassis, it is limited by increasing the diameter of the wheel body.
针对上述的技术问题,本申请的基本构思是提出一种底盘和机器人。将底盘拆分为两层:第一层用于使得承载力集中于与行走面垂直的垂直方向上;第二层用于保证整体结构更稳定。由于通过多个支撑柱垂直连接于底板上,保证了承载力可集中于垂直方向上,且底板连接多个支撑柱保证了整体结构的稳定性和平稳性。In view of the above technical problems, the basic idea of this application is to propose a chassis and a robot. Split the chassis into two layers: the first layer is used to concentrate the bearing capacity in the vertical direction perpendicular to the walking surface; the second layer is used to ensure the overall structure is more stable. Since the multiple support columns are vertically connected to the base plate, it is ensured that the bearing capacity can be concentrated in the vertical direction, and the base plate is connected with multiple support columns to ensure the stability and stability of the overall structure.
需要说明的是,本申请所提供的底盘可以应用于任何场景下的机器人。具体而言,机械结构的设计目的是要完成具体的工作任务,完成工作任务的方式为通过对应的机械结构或机械结构中的部分或全部组件以完成具体的机械动作或信息传递。It should be noted that the chassis provided in this application can be applied to robots in any scene. Specifically, the design purpose of the mechanical structure is to complete specific work tasks, and the way to complete the work tasks is to complete specific mechanical actions or information transmission through the corresponding mechanical structure or some or all components in the mechanical structure.
在介绍了本申请的基本原理之后,下面将参考附图来具体介绍本申请的各种非限制性实施例。After introducing the basic principles of the application, various non-limiting embodiments of the application will be described in detail below with reference to the accompanying drawings.

图7所示为本申请另外一些实现方式提供的底盘的悬架机构的立体结构示意图。如图7所示,在一种可能的实现方式中,第一弹性件143包括:安装轴1431和扭簧1433,安装轴1431横向安装,且安装轴1431构造为可转动。FIG. 7 is a schematic perspective view of a suspension mechanism of a chassis provided in some other implementation manners of the present application. As shown in FIG. 7 , in a possible implementation manner, the first elastic member 143 includes: an installation shaft 1431 and a torsion spring 1433 , the installation shaft 1431 is installed laterally, and the installation shaft 1431 is configured to be rotatable.
扭簧1433套接于安装轴1431上。其中,压板141连接于安装轴1431上。压板141可呈U形,使得压板141的两侧的板体分别与安装轴1431固定连接,以能够与安装轴1431同步转动。扭簧1433的一端与压板141抵接,扭簧1433的另一端与连杆120抵接,可理解为,扭簧1433的一端与压板141的底板连接,扭簧1433的另一端连接到第一端121,以使得扭簧1433的压紧力可以快速作用于驱动轮130。The torsion spring 1433 is sleeved on the installation shaft 1431 . Wherein, the pressing plate 141 is connected to the installation shaft 1431 . The pressing plate 141 can be U-shaped, so that the plates on both sides of the pressing plate 141 are respectively fixedly connected with the installation shaft 1431 so as to be able to rotate synchronously with the installation shaft 1431 . One end of the torsion spring 1433 abuts against the pressing plate 141, and the other end of the torsion spring 1433 abuts against the connecting rod 120. It can be understood that one end of the torsion spring 1433 is connected to the bottom plate of the pressing plate 141, and the other end of the torsion spring 1433 is connected to the first end 121, so that the compression force of the torsion spring 1433 can quickly act on the driving wheel 130.
更为具体地,继续结合图7所示,压板141驱动第一弹性件143压迫连杆120的动力机构可以为调节螺杆160,调节螺杆160与底盘固定架螺纹连接,调节螺杆160构造为旋进以与压板141相互抵接,或旋退以与压板141相互脱离。其中,底盘固定架上设有竖板,竖板上开设有螺纹孔,以穿设调节螺杆160。通过采用调节螺杆160作为动力机构,结构简单,调节方便,调节螺杆160的作用除了可以作为驱动压板141的动力,还可以根据底盘上面不同的负重调节扭簧1433的承受力,起到过坎和凹凸路面平稳过渡作用。More specifically, as shown in FIG. 7 , the power mechanism for the pressing plate 141 to drive the first elastic member 143 to press the connecting rod 120 can be an adjusting screw 160, which is screwed to the chassis fixing frame, and the adjusting screw 160 is configured to screw in to abut against the pressing plate 141 , or rotate back to disengage from the pressing plate 141 . Wherein, the chassis fixing frame is provided with a vertical plate, and the vertical plate is provided with threaded holes for passing the adjusting screw 160 . By adopting the adjustment screw 160 as the power mechanism, the structure is simple and the adjustment is convenient. The function of the adjustment screw 160 can not only be used as the power to drive the pressure plate 141, but also can adjust the bearing force of the torsion spring 1433 according to the different loads on the chassis, so as to play the role of crossing and Smooth transition effect on uneven road surface.
更为具体地,当调节螺杆160向前调节推进使压板141通过安装轴1431沿逆时针旋转时,扭簧1433接触压板141的一端受压后,导致扭簧1433跟连杆120接触的一端向下施压,然后使驱动轮130跟地面增加摩擦力。同时拉簧的下端固定在转动轴323上,牵引件的上端固定在底盘框架上,确保在调节螺杆160向前调节推进使压板141通过安装轴1431沿逆时针旋转时,扭簧1433接触压板141的一端受压后底盘整体过度上仰而后翻。More specifically, when the adjusting screw 160 is adjusted and pushed forward to make the pressure plate 141 rotate counterclockwise through the installation shaft 1431, the end of the torsion spring 1433 contacting the pressure plate 141 is pressed, causing the end of the torsion spring 1433 in contact with the connecting rod 120 to Press down, and then make the driving wheel 130 increase the frictional force with the ground. At the same time, the lower end of the extension spring is fixed on the rotating shaft 323, and the upper end of the traction member is fixed on the chassis frame, so as to ensure that when the adjusting screw 160 is adjusted and pushed forward to make the pressing plate 141 rotate counterclockwise through the mounting shaft 1431, the torsion spring 1433 contacts the pressing plate 141 After one end of the chassis is under pressure, the chassis as a whole is tilted up excessively and then turned over.
由于扭簧1433的特性是线性变形,所以在整体过坎的过程中释放和承压的力都是比较平稳的,再通过拉簧的拉力使底盘在过坎过程中所产生的震动被制约从而减小了缓冲。Since the characteristic of the torsion spring 1433 is linear deformation, the force of releasing and bearing pressure is relatively stable during the overall hurdle-crossing process, and the vibration generated by the chassis during the ridge-passing process is restricted by the tension of the extension spring. Reduced buffering.

示例性复式导向轮Exemplary Duplex Guide Wheels
图10所示为本申请一些实现方式提供的底盘的复式导向轮的立体结构示意图。如图10所示,该复式导向轮110包括:导向轮111和辅助轮113。FIG. 10 is a schematic perspective view of the three-dimensional structure of the multiple guide wheels of the chassis provided in some implementations of the present application. As shown in FIG. 10 , the composite guide wheel 110 includes: a guide wheel 111 and an auxiliary wheel 113 .
具体地,导向轮111构造为与行走面相互接触。具体地,辅助轮113设于导向轮111的一侧,辅助轮113与导向轮111偏心设置,使得辅助轮113在前进方向上凸出于导向轮111,并使得导向轮111与水平面的切线和辅助轮113与水平面的切线之间具有高度差H,且辅助轮113悬空,从而使得复式导向轮110在前进方向上,辅助轮113能够与坎先接触。Specifically, the guide wheels 111 are configured to be in contact with the running surface. Specifically, the auxiliary wheel 113 is arranged on one side of the guide wheel 111, and the auxiliary wheel 113 is eccentrically arranged with the guide wheel 111, so that the auxiliary wheel 113 protrudes from the guide wheel 111 in the forward direction, and the tangent between the guide wheel 111 and the horizontal plane and There is a height difference H between the auxiliary wheel 113 and the tangent of the horizontal plane, and the auxiliary wheel 113 is suspended in the air, so that the auxiliary wheel 113 can contact the ridge first in the forward direction of the compound guide wheel 110 .
更为具体地,导向轮111构造为与行走面相互接触。复式导向轮110未过坎之前,由于辅助轮113悬空,导向轮111与地面相互接触,由于坎的高度高出地面,且辅助轮在前进方向上凸出导向轮111,因此,在过坎过程中,辅助轮113先与坎相互接触,在摩擦力的作用下,辅助轮113沿着坎爬升,从而带动导向轮111爬上坎,当辅助轮113爬升到高度差H的高度,则导向轮111与坎接触,使得导向轮111再带动辅助轮113继续爬坎,直至越过坎,从而通过两个阶段的过坎方式,复式导向轮110能够爬过坎。其中,辅助轮113可以爬过的坎的高度,与导向轮与水平面的切线和辅助轮与水平面的切线之间所形成的高度差相对应。因此,只要设计合适的高度差,复式导向轮111就可以越过相当高度的坎,然后导向轮111再越过坎,通过将导向轮111的过坎过程拆分为两个阶段来实现,从而提高了复式导向轮110能够越过的坎的高度的范围,也就提高了复式导向轮110的应用范围。More specifically, the guide wheels 111 are configured to be in contact with the running surface. Before the compound guide wheel 110 crosses the ridge, because the auxiliary wheel 113 is in the air, the guide wheel 111 is in contact with the ground. Since the height of the ridge is higher than the ground, and the auxiliary wheel protrudes from the guide wheel 111 in the forward direction, therefore, in the process of crossing the ridge, In the process, the auxiliary wheel 113 first contacts with the ridge, and under the action of friction, the auxiliary wheel 113 climbs along the ridge, thereby driving the guide wheel 111 to climb up the ridge. When the auxiliary wheel 113 climbs to the height of the height difference H, the guide wheel 111 is in contact with the ridge, so that the guide wheel 111 drives the auxiliary wheel 113 to continue climbing the ridge until the ridge is crossed, so that the multiple guide wheels 110 can climb over the ridge through the two-stage way of crossing the ridge. Wherein, the height of the ridge that the auxiliary wheels 113 can climb is corresponding to the height difference formed between the tangent line between the guide wheel and the horizontal plane and the tangent line between the auxiliary wheel and the horizontal plane. Therefore, as long as the suitable height difference is designed, the compound guide wheel 111 can cross over a ridge of considerable height, and then the guide wheel 111 crosses the ridge again, and realizes by splitting the process of crossing the ridge of the guide wheel 111 into two stages, thereby improving the The range of the height of the ridge that the compound guide wheel 110 can cross also increases the application range of the compound guide wheel 110 .
图11所示为图10所示的实现方式提供的复式导向轮的主视结构示意图。如图11所示,辅助轮113与导向轮111在轴向上的投影部分重叠,可以理解为,辅助轮113与导向轮111偏心设置,至少在前进方向上形成有偏心距离,辅助轮113在前进方向上凸出于导向轮111,但是,辅助轮113与导向轮111在前进方向上的偏心 距离小于辅助轮113的半径与导向轮111的半径之和,因此,复合导向轮110在过坎时,辅助轮113先与坎接触爬坡,导向轮111再与坎接触爬坡,从而可以保证复式导向轮110分两个阶段过坎。FIG. 11 is a schematic front view of the structure of the multiple guide wheels provided by the implementation shown in FIG. 10 . As shown in Figure 11, the auxiliary wheel 113 overlaps with the axial projection of the guide wheel 111. It can be understood that the auxiliary wheel 113 is eccentrically arranged with the guide wheel 111, at least forming an eccentric distance in the forward direction. Protrude from the guide wheel 111 in the advancing direction, but the eccentric distance between the auxiliary wheel 113 and the guiding wheel 111 in the advancing direction is less than the sum of the radius of the auxiliary wheel 113 and the radius of the guiding wheel 111. At this time, the auxiliary wheel 113 first contacts with the ridge to climb the slope, and the guide wheel 111 contacts with the ridge to climb the slope, so that the compound guide wheel 110 can be guaranteed to cross the ridge in two stages.
另外,由于复式导向轮110具有至少一个辅助轮113,因此,该复式导向轮110可以实现单边通过障碍物。In addition, since the compound guide wheel 110 has at least one auxiliary wheel 113, the compound guide wheel 110 can pass obstacles on one side.
继续结合如图11所示,在一种可能的实现方式中,辅助轮113与导向轮111之间具有第一偏心距A1和第二偏心距A2,可以理解为,第一偏心距A1为辅助轮113与导向轮111在前进方向上形成的偏心距离。辅助轮113与导向轮111之间具有两个偏心距,即第一偏心距A1为水平方向上的偏心距,第二偏心距A2为高度差方向上的偏心距,也就是垂直偏心距。第一偏心距A1使得辅助轮113在前进方向上凸出于导向轮111,第二偏心距A2使得辅助轮113悬空。从而使得导向轮111既能够满足在一定的直径范围内转动的要求,又能够满足高度差H,使得在行走方向上,辅助轮113能够与坎先接触。Continuing to show in FIG. 11 , in a possible implementation, there is a first eccentricity A1 and a second eccentricity A2 between the auxiliary wheel 113 and the guide wheel 111. It can be understood that the first eccentricity A1 is the auxiliary The eccentric distance formed between the wheel 113 and the guide wheel 111 in the forward direction. There are two eccentricities between the auxiliary wheel 113 and the guide wheel 111, that is, the first eccentricity A1 is the eccentricity in the horizontal direction, and the second eccentricity A2 is the eccentricity in the height difference direction, that is, the vertical eccentricity. The first eccentricity A1 makes the auxiliary wheel 113 protrude from the guide wheel 111 in the forward direction, and the second eccentricity A2 makes the auxiliary wheel 113 suspended. Therefore, the guide wheel 111 can not only meet the requirement of rotating within a certain diameter range, but also meet the height difference H, so that in the walking direction, the auxiliary wheel 113 can contact the ridge first.
继续结合图11所示,在一种可能的实现方式中,第一偏心距A1为水平偏心距,其中,在确定高度差辅助轮113的底部水平切线与辅助轮113的外径相切,形成水平切线点C,辅助轮113的水平切线点C位于导向轮111的外径上,以获得第一偏心距A1,为最优的第一偏心距,使得复式导向轮110在过坎的过程中更平稳。Continuing to show in FIG. 11 , in a possible implementation manner, the first eccentricity A1 is a horizontal eccentricity, wherein the horizontal tangent at the bottom of the auxiliary wheel 113 at the determined height difference is tangent to the outer diameter of the auxiliary wheel 113, forming The horizontal tangent point C, the horizontal tangent point C of the auxiliary wheel 113 is located on the outer diameter of the guide wheel 111, so as to obtain the first eccentricity A1, which is the optimal first eccentricity, so that the compound guide wheel 110 is in the process of crossing the ridge more stable.
更为具体地,以三寸导向轮为例,也就是,导向轮111的半径为75毫米,辅助轮113半径为80毫米。高度差H为6.5毫米至13毫米,最优可以选取9.5毫米至10毫米,提高了复式导向轮110能够过坎的高度。第一偏心距A1为20毫米至26毫米,可以优选为23毫米,在同类3寸导向轮中是比较小的,这样的偏心距可以更好的完成小半径的转向。其中,导向轮111可以为万向轮。More specifically, taking a three-inch guide wheel as an example, that is, the radius of the guide wheel 111 is 75 mm, and the radius of the auxiliary wheel 113 is 80 mm. The height difference H is 6.5 mm to 13 mm, and optimally 9.5 mm to 10 mm, which improves the height at which the compound guide wheels 110 can cross the ridge. The first eccentricity A1 is 20 mm to 26 mm, preferably 23 mm, which is relatively small among similar 3-inch guide wheels, and such an eccentricity can better complete small-radius steering. Wherein, the guide wheel 111 may be a universal wheel.
继续结合图11所示,在一种可能的实现方式中,高度差H为导向轮111的半径的1/2至1/8,可以理解为,高度差H可以为导向轮半径的1/2、导向轮半径的1/5、导向轮半径的1/8。Continuing to show in Figure 11, in a possible implementation, the height difference H is 1/2 to 1/8 of the radius of the guide wheel 111, it can be understood that the height difference H can be 1/2 of the radius of the guide wheel , 1/5 of the radius of the guide wheel, and 1/8 of the radius of the guide wheel.
继续结合图10所示,在一种可能的实现方式中,辅助轮113设置为两个,两个辅助轮113分别设于导向轮111的相对两侧,两个辅助轮113同轴设置。其中,辅助轮113转动连接于轮轴117上,且两个辅助轮113分别设于导向轮111的相对两侧,使得复式导向轮110的在行走过程中更稳平稳,且具有一定的承重能力。Continuing to show in FIG. 10 , in a possible implementation manner, there are two auxiliary wheels 113 , the two auxiliary wheels 113 are respectively arranged on opposite sides of the guide wheel 111 , and the two auxiliary wheels 113 are arranged coaxially. Wherein, the auxiliary wheel 113 is rotatably connected to the wheel shaft 117, and the two auxiliary wheels 113 are respectively arranged on opposite sides of the guide wheel 111, so that the compound guide wheel 110 is more stable during walking and has a certain load-bearing capacity.

As shown in Figure 13, the side plate 1153 has a curved portion, so that the cross-section of the side plate 1153 becomes a U-shape with an outwardly protruding structure, and the protruding portion of the curved portion faces the auxiliary wheel 113, so that it is placed in the accommodating space The wheel body of the guide wheel 111 will not interfere with the side plate 1153, and the structural strength of the side plate 1153 can be improved. The wheel body of the guiding wheel 111 is located in the accommodating space, and the auxiliary wheel 113 is located outside the accommodating space, so that mutual interference between the guiding wheel 111 and the auxiliary wheel 113 can be avoided.
