Description

电动扳手及电动扳手***Electric wrench and electric wrench system 技术领域technical field
本申请属于电动工具领域，尤其涉及一种电动扳手及电动扳手***。The application belongs to the field of electric tools, and in particular relates to an electric wrench and an electric wrench system.
背景技术Background technique
随着我国的汽车拥有量的不断增加，汽车工具也不断丰富，尤其是一些紧急庇护工具，如启动电源、打气泵、千斤顶等，成为车辆出行的必备工具。传统的电动扳手在使用时需插电才能工作，使用环境受限和有束缚极其不方便。现有的各种交通工具、装置或者电子设备一般会配置有自带电源以给内部的各种组件提供电能。例如，汽车电瓶是用于给汽车上的各种电子设备供电的装置。随着电池材料技术的发展，电池的容量已被大幅度提升，其应用范围已经从一些小功率的电子类电气装置延伸到一些大功率的动力类电气装置，如电动扳手等。With the continuous increase of the number of cars in our country, car tools are also constantly enriched, especially some emergency protection tools, such as starting power, air pumps, jacks, etc., have become necessary tools for vehicle travel. The traditional electric wrench needs to be plugged in to work, and the use environment is limited and bound, which is extremely inconvenient. Existing vehicles, devices or electronic equipment are generally equipped with their own power supply to provide power to various internal components. For example, a car battery is the device used to power various electronic devices in a car. With the development of battery material technology, the capacity of batteries has been greatly improved, and its application range has been extended from some low-power electronic electrical devices to some high-power power electrical devices, such as electric wrenches.
然而，现有的电动扳手的电池性能较为单一，即只能用于为电动扳手供电，当电动扳手处于闲置状态(电动扳手不需要工作)时，电池则处于闲置状态，使得电动扳手电池的利用率较低。而电池若长期不使用将会导致电池容量及使用寿命下降，进而影响电池的性能。However, the battery performance of the existing electric wrench is relatively single, that is, it can only be used to supply power to the electric wrench. The rate is lower. If the battery is not used for a long time, the capacity and service life of the battery will decrease, which will affect the performance of the battery.
另一方面，与电池配合使用的无线电动扳手往往只能作为电动扳手使用，功能十分单一。而且无线电动扳手为了实现电动，需要携带电池，致使其十分笨重。过重的重量和较为单一的功能，降低了用户购买及携带无线电动扳手的动力。On the other hand, the wireless electric wrench used in conjunction with the battery can only be used as an electric wrench, and its function is very single. Moreover, in order to realize electric movement, the wireless electric wrench needs to carry batteries, which makes it very heavy. Excessive weight and relatively single function reduce the motivation of users to purchase and carry wireless electric wrench.
