Description

用于清洁设备的边刷组件及清洁设备Side brush assembly for cleaning equipment and cleaning equipment 技术领域technical field
本申请涉及清洁设备领域，特别涉及边刷组件及清洁设备。The present application relates to the field of cleaning equipment, in particular to a side brush assembly and cleaning equipment.
背景技术Background technique
现有的洗地车、扫地车、扫地机器人等清洁设备逐渐代替了人力，边刷是这些清洁设备中的常用部件。边刷一般可旋转地安装于上述清洁设备的底部，并且因与地面接触而长时间地保持摩擦。边刷非常容易磨损，需要定期更换。因此，边刷拆卸和安装的便利性直接影响清洁设备的维护效率和操作者的使用体验。Existing cleaning equipment such as floor washing vehicles, floor sweeping vehicles, and floor sweeping robots have gradually replaced manpower, and side brushes are common components in these cleaning equipment. The side brushes are generally rotatably mounted on the bottom of the above-mentioned cleaning equipment, and maintain friction for a long time due to contact with the ground. The side brushes are very prone to wear and need to be replaced periodically. Therefore, the convenience of removing and installing the side brush directly affects the maintenance efficiency of the cleaning equipment and the user experience of the operator.
较为常见地，上述清洁设备的底部设置有支架或底座，电机被固定在支架或底座上，边刷先与转接件通过螺钉固定连接后，再凭借转接件设置于电机的输出轴上，从而以电机的输出轴带动边刷旋转。虽然这种以螺钉固定连接的方式比较牢固，但是每次拆卸和安装边刷均需要借助工具(例如，拆卸螺钉一侧需要利用螺丝刀，拆卸螺母一侧需要利用扳手)，因此导致缺少工具时操作者没有办法更换边刷，即使有工具更换效率也较低。More commonly, the bottom of the above-mentioned cleaning equipment is provided with a bracket or a base, and the motor is fixed on the bracket or base. After the side brush is fixedly connected with the adapter by screws, it is then set on the output shaft of the motor by means of the adapter. Thus, the output shaft of the motor drives the side brush to rotate. Although this method of screw-fixed connection is relatively strong, tools are required for each removal and installation of the side brush (for example, a screwdriver is required to remove the screw side, and a wrench is required to remove the nut side), so it is necessary to operate without tools Or there is no way to replace the side brush, even if there are tools, the replacement efficiency is also low.

As shown in FIG. 5 a , when there are two manipulating portions 33 a (recessed portions), they are distributed at intervals of 180° in the circumferential direction. As shown in FIG. 5 b , when there are five manipulating portions 33 a (recessed portions), they are distributed at intervals of 72° in the circumferential direction. As shown in FIG. 5c, when there are six manipulating portions 33a (recessed portions), they are distributed at intervals of 60° in the circumferential direction.
优选地，操纵部33a(凹陷部)的数量为偶数，例如二、四、六个。更优选地，操纵部33a(凹陷部)具有六个，即整个锁止件33如图5c所示的那样呈六角星形。这样，无论以两指或三指旋拧锁止件33都会比较方便、舒适。Preferably, the number of manipulation portions 33a (recessed portions) is an even number, such as two, four, or six. More preferably, there are six manipulating portions 33 a (recessed portions), that is, the entire locking member 33 is in the shape of a hexagonal star as shown in FIG. 5 c . In this way, it will be more convenient and comfortable to twist the locking member 33 with two fingers or three fingers.
本领域技术人员应当能够理解，通常人的手腕的转动角度受限，并且人在以手指旋拧物体的过程中需要对物体施力，这就导致人在将物体旋转很小的角度(一般不超过60°)后要重新为手指寻找施力点。考虑到这样的因素，操纵部33a(凹陷部)的数量被设计为4～6个，比较有利于人的手指快速地寻找下一个施力点。另外，考虑到人以两根手指旋转物体时，施力点通常位于相对侧，以三根手指旋转物体时，施力点通常呈三角关系，因此选择六个操纵部33a(凹陷部)是更为便利的。Those skilled in the art should be able to understand that usually the rotation angle of a person's wrist is limited, and the person needs to apply force to the object during the process of twisting the object with fingers, which causes the person to rotate the object at a small angle (generally not After exceeding 60°), it is necessary to find the force point for the finger again. Considering such factors, the number of manipulating parts 33a (recessed parts) is designed to be 4-6, which is more conducive to people's fingers to quickly find the next force application point. In addition, considering that when a person rotates an object with two fingers, the force application point is usually located on the opposite side, and when the object is rotated with three fingers, the force application point is usually in a triangular relationship, so it is more convenient to choose six manipulation parts 33a (depressed parts) .
进一步地，参照图3a～3b和图4所示，限位部31b为沿转接件31的径向形成的凸台。凸台朝向螺纹部31a一侧上设置有定位柱31c。边刷32具有能够套设在螺纹部31a上的安装孔32a以及与所述定位柱31c匹配的定位孔32b，当边刷32被固定在转接件31上时，定位柱31c与定位孔32b相结合，限制边刷32相对于转接件31旋转。Further, referring to FIGS. 3 a - 3 b and FIG. 4 , the limiting portion 31 b is a boss formed along the radial direction of the adapter piece 31 . A positioning column 31c is provided on the side of the boss facing the threaded portion 31a. The side brush 32 has a mounting hole 32a that can be sleeved on the threaded portion 31a and a positioning hole 32b that matches the positioning post 31c. When the side brush 32 is fixed on the adapter 31, the positioning post 31c and the positioning hole 32b In combination, the rotation of the side brush 32 relative to the adapter 31 is restricted.
更进一步地，所述凸台为环状的法兰面。所述定位柱31c至少具有两个且均匀地分布在所述法兰面上。边刷32上的定位孔32b的数量与所述定位柱31c的数量相应。Furthermore, the boss is an annular flange surface. There are at least two positioning posts 31c and they are evenly distributed on the flange surface. The number of positioning holes 32b on the side brush 32 corresponds to the number of the positioning posts 31c.
本领域技术人员应当能够理解，限位部31b可以是像图3a中所示那样由转接件31的径向形成凸台，限位部31b并非一定是环状的法兰面，限位部31b也可以是对称地或者非对称地形成于转接件31上的非连续的凸起，只要使凸台可以成为限位部31b以限制边刷32的运动即可。限位部31b也可以是像图3b中所示那样，是由于连接部31d和螺纹部31a的直径不同而形成台阶。换句话说，螺纹部31a的直径小于连接部31d的直径，以使螺纹部31a与连接部31d之间形成台阶状的限位部31b。Those skilled in the art should be able to understand that the limiting portion 31b can be a boss formed by the radial direction of the adapter 31 as shown in FIG. 31b may also be a discontinuous protrusion formed symmetrically or asymmetrically on the adapter 31 , as long as the protrusion can be used as a limiting portion 31b to limit the movement of the side brush 32 . The limiting portion 31b may also be a step as shown in FIG. 3b , because the diameters of the connecting portion 31d and the threaded portion 31a are different. In other words, the diameter of the threaded portion 31a is smaller than the diameter of the connecting portion 31d, so that a stepped limiting portion 31b is formed between the threaded portion 31a and the connecting portion 31d.
另外，本领域技术人员应当能够理解，虽然图3b中没有示出定位柱31c，但是根据需要也可以添加定位柱31c，从而防止边刷32相对于转接件31旋转。In addition, those skilled in the art should be able to understand that although the positioning post 31c is not shown in FIG. 3b , the positioning post 31c can also be added as required, so as to prevent the side brush 32 from rotating relative to the adapter 31 .
在实际使用中，边刷组件30安装在清洁设备底部，当边刷32磨损严重需要更换时，维护人员可以利用操纵部33a(凹陷部)轻松地转动锁止件 33，从而拆卸旧的边刷32。在更换新的边刷32时，需要将定位孔32b与定位柱31c对齐地将边刷32套设于螺纹部31a上，最后以锁止件33将更换后新的边刷32固定于转接件31上。由此，可以不使用专门的工具，直接以手动旋拧的方式实现边刷32的拆卸和更换，该边刷组件30维护简单、方便、高效。In actual use, the side brush assembly 30 is installed at the bottom of the cleaning equipment. When the side brush 32 is seriously worn and needs to be replaced, the maintenance personnel can use the manipulation part 33a (depressed part) to easily turn the locking part 33 to remove the old side brush 32. When replacing a new side brush 32, it is necessary to align the positioning hole 32b with the positioning post 31c to sleeve the side brush 32 on the threaded part 31a, and finally use the locking member 33 to fix the new side brush 32 on the adapter. Item 31 on. Therefore, the side brush 32 can be disassembled and replaced directly by manual screwing without using special tools, and the maintenance of the side brush assembly 30 is simple, convenient and efficient.
进一步地，继续参照图3a～3b，转接件31具有轴向的贯通的中心孔31e，转接件31能够经由中心孔31e与电机20的输出轴固定连接。Further, referring to FIGS. 3 a to 3 b , the adapter 31 has an axial through center hole 31 e, and the adapter 31 can be fixedly connected to the output shaft of the motor 20 through the center hole 31 e.
在一种实施方式中，转接件31采用挠性材料制成，转接件31可以经由中心孔31e与电机20的输出轴过盈配合。In one embodiment, the adapter 31 is made of flexible material, and the adapter 31 can be interference fit with the output shaft of the motor 20 through the central hole 31e.
在另一种实施方式中，转接件31上形成有与轴向的中心孔31e连通的径向的紧固孔31f，紧固件(图未示)能够设置于紧固孔31f内的，当紧固件穿过紧固孔31f抵触于所述电机20的输出轴上时，电机20的输出轴被固定在中心孔31e内。In another embodiment, the adapter 31 is formed with a radial fastening hole 31f communicating with the axial central hole 31e, and a fastener (not shown) can be arranged in the fastening hole 31f, When the fastener passes through the fastening hole 31f and interferes with the output shaft of the motor 20, the output shaft of the motor 20 is fixed in the central hole 31e.
本领域技术人员应当能够理解，转接件31上的中心孔31e也可以是非贯通的，只要其能够容纳电机20的输出轴即可。紧固件可以采用螺钉或者销钉等。Those skilled in the art should be able to understand that the central hole 31 e on the adapter 31 may also be non-through, as long as it can accommodate the output shaft of the motor 20 . Fasteners can be screws or pins.
