基于同一发明构思，本申请还提供一种用电设备。具体地，请参阅图21，其示出了该用电设备1的示意图，该用电设备1包括支架20以及上述任一实施例中的电池，该电池安装于上述支架20。本实施例中，用电设备1包括圆形的清洁机器人，该清洁机器人包括上述支架20与上述的电池；接下来，以该清洁机器人包括上述电池10为例，对该用电设备1的具体结构作出说明；可以理解的是，在本申请的其他实施例中，用电设备1亦可以是电动车、电饭煲等其他用电设备。Based on the same inventive concept, the present application also provides an electrical device. Specifically, please refer to FIG. 21 , which shows a schematic diagram of theelectrical equipment 1 , theelectrical equipment 1 includes abracket 20 and a battery in any of the above-mentioned embodiments, and the battery is installed on the above-mentionedbracket 20 . In this embodiment, theelectrical equipment 1 includes a circular cleaning robot, and the cleaning robot includes the above-mentionedbracket 20 and the above-mentioned battery. Next, taking the cleaning robot including the above-mentionedbattery 10 as an example, the specific The structure is explained; it can be understood that, in other embodiments of the present application, theelectrical equipment 1 may also be other electrical equipment such as an electric vehicle and an electric rice cooker.

用电设备1包括支架20、电池10以及其他的器件，如电机、风机等。其中，支架20整体呈圆柱形，其内部设有容置腔21，用以收容电池10以及上述的电机等器件。容置腔21具体包括一自容置腔21的轴线向外扩张形成的柱形的第一容置空间21a，以及环绕于第一容置空间21a外周的环形的第二容置空间21b，该第二容置空间21b位于第一容置空间21a与容置腔21的内壁之间。Theelectrical device 1 includes abracket 20 , abattery 10 and other devices, such as a motor, a fan, and the like. Thebracket 20 has a cylindrical shape as a whole, and anaccommodating cavity 21 is provided inside thebracket 20 for accommodating thebattery 10 and the above-mentioned devices such as the motor. Theaccommodating cavity 21 specifically includes a cylindrical firstaccommodating space 21a formed by expanding outward from the axis of theaccommodating cavity 21, and an annular secondaccommodating space 21b surrounding the periphery of the firstaccommodating space 21a. The secondaccommodating space 21b is located between the firstaccommodating space 21a and the inner wall of theaccommodating cavity 21 .

容置腔21中除电池10之外的大多数器件布置在上述第一容置空间21a；第二容置空间21b包括用于安置电池10的弯曲形电池仓区域，电池10设于上述电池仓区域。具体地，电池10的收容壳100呈弯曲延伸以形成内凹的一侧与外凸的一侧，该收容壳100内凹的一侧朝向容置腔21的中心设置，该收容壳100外凸的一侧靠近或贴合于容置腔21的内壁设置。Most of the devices in theaccommodating cavity 21 except thebattery 10 are arranged in the above-mentioned firstaccommodating space 21a; the secondaccommodating space 21b includes a curved battery compartment area for accommodating thebattery 10, and thebattery 10 is arranged in the above-mentioned battery compartment area. Specifically, theaccommodating case 100 of thebattery 10 is bent and extended to form a concave side and an outer convex side. The concave side of theaccommodating case 100 is disposed toward the center of theaccommodating cavity 21 , and theaccommodating case 100 is convex. One side of the device is set close to or attached to the inner wall of theaccommodating cavity 21 .

目前市场上的清洁机器人，其容置腔内部包括电池在内的所有器件均集中布置于上述第一容置空间，第二容置空间的设置旨在避免外围器件的轮廓与第一容置空间21a的内壁干涉，但其导致该第二容置空间难以利用，即是使清洁机器人的空间利用率较低，难以实现小型化设计。而本实施例中的电池10能够很好的利用上用电设备1中环形的第二容置空间21b，从而可有效减小第一容置空间21a的体积，进而减小清洁机器人的整体体积，有利于清洁机器人小型化设计的实现。In the cleaning robots currently on the market, all the devices including the battery in the accommodating cavity are centrally arranged in the above-mentioned first accommodating space, and the setting of the second accommodating space aims to avoid the contour of the peripheral devices and the first accommodating space. The inner wall of 21a interferes, but it makes it difficult to use the second accommodating space, that is, the space utilization rate of the cleaning robot is low, and it is difficult to realize a miniaturized design. Thebattery 10 in this embodiment can make good use of the annular secondaccommodating space 21b in the upperelectrical equipment 1, thereby effectively reducing the volume of the firstaccommodating space 21a, thereby reducing the overall volume of the cleaning robot , which is conducive to the realization of the miniaturized design of cleaning robots.

进一步地，为使得电池10的能量尽可能多，应保证电池10体积最大，即是使第一部分110、第二部分120以及第三部分130的体积尽可能大，接下来先以第一部分110体积最大的确定方式为例作出说明，具体如下：Further, in order to make the energy of the battery 10 as much as possible, the volume of the battery 10 should be the largest, that is, the volume of the first part 110 , the second part 120 and the third part 130 should be made as large as possible. The maximum determination method is illustrated as an example, as follows:

第一部分110呈平直延伸，当第二容置空间21b的高度、内径R1以及外径R2都确定时，应确保第一部分110于垂直于容置腔21轴线的截面面积最大。为便于说明，以下将第一部分110在该截面上的宽度定义为宽度T，将第一部分110在该截面上的长度定义为长度L，将第一部分110于垂直于容置腔21轴线的截面面积定位为面积S，则申请人可得到以下公式：The first part 110 extends straight. When the height, inner diameter R1 and outer diameter R2 of the second accommodating space 21b are determined, it should be ensured that the cross-sectional area of the first part 110 perpendicular to the axis of the accommodating cavity 21 is the largest. For the convenience of description, the width of the first part 110 on the cross section is defined as the width T, the length of the first part 110 on the cross section is defined as the length L, and the cross-sectional area of the first part 110 perpendicular to the axis of the accommodating cavity 21 is defined as Positioned as area S, the applicant can get the following formula:

S＝TL； (2)S=TL; (2)

申请人根据上述两公式可确定，当

时，

时，面积S最大。According to the above two formulas, the applicant can determine that when

hour,

, the area S is the largest.

此外，第三部分130与第二部分110体积最大的确定方式大致相同，在此不作赘述。In addition, the method for determining the largest volume of thethird part 130 and thesecond part 110 is substantially the same, and details are not described here.

本申请实施例提供的用电设备1的电池10呈弯曲延伸的形状，故该电池10可以适配用电设备1中弯曲形状的电池仓，用电设备1的空间利用率较高。Thebattery 10 of theelectrical device 1 provided in the embodiment of the present application is in a curved and extended shape, so thebattery 10 can be adapted to the curved battery compartment in theelectrical device 1, and the space utilization rate of theelectrical device 1 is high.
