Problems solved by technology

[0003] As electric tools are getting smarter and more widely used, with the development of the sharing economy, electric tools are provided to end users in the form of leasing. At this time, high-end electric tools have to switch between different control strategies, which requires Update the control program of the existing electric tool. At present, when updating the program of the electric tool, because there is no I / O communication interface reserved on the electric tool, the electric tool must be disassembled, and then the control chip must be taken out. It is very troublesome to connect the I / O communication interface of the control chip to the programmer to burn and update the program, and then install the electric tool, and disassembling and assembling the tool consumes a lot of time

Abstract

The invention relates to a device and a method for updating the control program of a portable electric tool. The device comprises a programmer, a USB interface used for connecting a PC terminal and the programmer, a program output terminal electrically connected with the programmer, a program updating control button used for sending a programming instruction to the programmer and a program checking code reading button used for sending a checking instruction to the programmer, wherein the program output terminal is used for being connected with a battery pack temperature detection terminal in abattery clamp of an electric tool. According to the device, the program output terminal, the program updating control button and the program checking code reading button which are in butt joint withthe battery pack temperature detection terminal are arranged on the programmer to realize the program updating of an electric tool control chip by the updating device through the battery pack temperature detection terminal, so that the control program of the electric tool can be updated without disassembling the electric tool, the program updating difficulty of the electric tool is effectively reduced, and the program updating time of the electric tool is shortened.

Description

Technical field: [0001] The invention relates to a portable electric tool control program updating device and updating method. Background technique: [0002] Portable electric tools refer to electric tools powered by mobile power sources, such as rechargeable electric drills, rechargeable electric hammers, etc. These portable electric tools have detachable battery packs, which can be removed for charging when the battery pack is about to run out. After charging the bag, install it on the power tool again for use. The structure connected to the battery pack on the electric tool is a battery clip. There are three contacts on the battery clip, which are respectively connected to the positive pole, negative pole and thermistor on the battery pack. The thermistor is connected to the positive pole or negative pole, and the thermal sensor The contact piece of the resistor (battery pack temperature detection terminal) is electrically connected to the control chip in the electric to...
