Background

With the increasing of the quantity of automobiles in China, automobile tools are also abundant, and especially some emergency sheltering tools, such as a starting power supply, an inflating pump, a jack and the like, become necessary tools for the traveling of the vehicles. The traditional electric tool can work only by plugging in electricity when in use, and the use environment is limited and is extremely inconvenient to bind. Various vehicles, devices, or electronic equipment are typically configured with their own power source to provide power to the various components within. For example, an automotive battery is a device used to power various electronic devices on an automobile. With the development of battery material technology, the capacity of the battery has been greatly improved, and the application range of the battery has been extended from some low-power electronic type electric devices to some high-power type electric devices, such as electric tools and the like.

Further, referring to fig. 6 and 7, the power supply device 32 will be described in detail below. The power supply device 32 includes a power supply output interface 321. When the power supply device 32 is connected to the electric power tool 10, the power supply input interface 125 is electrically connected to the power supply output interface 321, and the power supply device 32 supplies power to the electric power tool 10 through the power supply output interface 321. Thus, the power supply device 32 can supply driving power for the rotation of the operating head 123. Moreover, when the power device 32 is no longer connected to the power tool 10, the power device 32 can be used as a mobile power source to charge an external device through the power output interface 321, or the power output interface of the power device 32 can be connected to a battery through a battery clamp to output current to assist the battery in starting the vehicle.

In this embodiment, the power input interfaces 125 correspond to the power output interfaces 321 one by one, and both of them are one. It is understood that the power input interfaces 125 and the power output interfaces 321 may not correspond to each other, that is, the number of the power input interfaces 125 is greater than or less than the number of the power output interfaces 321. It should be understood that the number of the power input interfaces 125 and the power output interfaces 321 is not limited in the present application, and may be one or more.

The power output interface 321 includes a first power output interface 3211, a second power output interface 3212, and a second communication port 3213, where the first power output interface 3211 is used to connect the first power input interface 1251, the second power output interface 3212 is used to connect the second power input interface 1253, and the second communication port 3213 is used to connect the first communication port 1255.

When the power output interface 321 of the power supply device 32 is connected to the power input interface 125 of the electric power tool 10, the first power output interface 3211 is connected to the first power input interface 1251, the second power output interface 3212 is connected to the second power input interface 1253, and the second communication port 3213 is connected to the first communication port 1255. The connection of the first power output interface 3211 to the first power input interface 1251 and the connection of the second power output interface 3212 to the second power input interface 1253 form a power path between the electric power tool 10 and the power supply device 32, and the power supply device 32 supplies power to the electric power tool 10 through the power path. The connection between the second communication port 3213 and the first communication port 1255 forms a signal path between the power tool 10 and the power supply device 32, and the power supply device 32 outputs various signals to the power tool 10 through the signal path. The signal may be, but is not limited to, a temperature signal, a cell over-temperature signal, or a low-voltage energy protection signal. Taking the temperature signal as an example for explanation, when the temperature of the power supply device 32 when supplying power to the electric tool 10 is too high, so that the power supply device 32 is at risk of being burnt, the temperature signal controls the power supply device 32 to stop supplying power to the electric tool 10 until the temperature of the power supply device 32 is reduced to meet the requirement, so that the power supply device 32 can be prevented from being burnt when supplying power to the electric tool 10, and the service life of the power supply device 32 is greatly prolonged. Of course, the power tool 10 may also be provided with a heat dissipation fan (not shown), and when the temperature of the power device 32 supplying power to the power tool 10 is too high, so that the power device 32 may be at risk of burning, the temperature signal controls the heat dissipation fan to start to dissipate heat of the power device 32.

The port types of the second communication port 3213 and the first communication port 1255 are not specifically limited in this application.

It is understood that the first power output interface 3211 and the first power input interface 1251 are corresponding positive interfaces, and the second power output interface 3212 and the second power input interface 1253 are corresponding negative interfaces.

In the present embodiment, the end surface of the coupling end 320 is provided with a first groove 3201 and a second groove 3202, the first groove 3201 and the second groove 3202 are spaced apart, the first groove 3201 and the second groove 3202 have different shapes and/or the first groove 3201 and the second groove 3202 have different inner diameters; the first power output interface 3211 is disposed in the first groove 3201, the second power output interface 3212 and the second communication port 3213 are disposed in the second groove 3202, the second power output interface 3212 and the second communication port 3213 are disposed at an interval in the second groove 3202, and the second communication port 3213 is disposed between the first power output interface 3211 and the second power output interface 3212. The design of the first groove 3201 and the second groove 3202 prevents the first power output interface 3211 from mistakenly touching the second power input interface 1253 and/or the second power output interface 3212 from mistakenly touching the first power input interface 1251 when the first power output interface 3211 is connected to the first power input interface 1251 and the second power output interface 3212 is connected to the second power input interface 1253, thereby preventing the power supply device 32 from stopping supplying power to the electric tool 10 due to a short circuit and preventing the power supply device 32 from being burnt due to a short circuit, and prolonging the service life of the power supply device 32. Moreover, the second power output interface 3212 and the second communication port 3213 are disposed at an interval in the second groove 3202, and have different shapes and/or different inner diameters, so as to play a foolproof role, thereby preventing the first power input interface 1251 of the electric power tool 10 from being connected to the second power output interface 3212 of the power source device 32, and preventing the second power input interface 1253 of the electric power tool 10 from being connected to the first power output interface 3211 of the power source device 32, and improving the safety of the electric power tool 10 during use. It is understood that the second communication port 3213 may be disposed in the first groove 3201, and the second communication port 3213 is spaced apart from the first power output interface 3211 in the first groove 3201.

In the present embodiment, the charging interface 327 includes a Type-C interface, so that the power supply device 32 can be charged not only through the charging interface 327, but also as a mobile charger to charge a load device such as a mobile phone by outputting a voltage through the charging interface 327. It is to be understood that the interface Type of the charging interface 327 is not specifically limited in this application, and the charging interface 327 may further include a USB interface such as a Type-a interface or another Type of interface such as a DC interface.

In the present embodiment, charging interface 327 is provided on an end surface of coupling end 320. It is understood that charging interface 327 may be disposed on an end surface of body end 325 facing away from coupling end 320 or elsewhere, and the application is not limited thereto.

As shown in fig. 6 and 7, the power supply device 32 is further provided with a power amount display button 328 and at least one display lamp 329 provided on the peripheral surface of the body end 325. The power display button 328 may be connected to a display lamp 329, and the display lamp 329 is used to display the remaining amount of the power supply device 32. When the power supply device 32 is sufficiently stored, the user presses the electric quantity display button 328, and the display lamp 329 emits light; when the power supply device 32 is short of stock, the user presses the power display button 328, and the display lamp 329 does not emit light. Thus, the user can judge whether the storage amount of the power supply device 32 is sufficient by observing whether the display lamp 329 emits light, and the method is intuitive, convenient and easy to observe. Alternatively, the power display button 328 and the display lamp 329 may be connected to a controller, and the controller controls the lighting state of the display lamp 329 based on the power in the power supply device 32 in response to a pressing signal of the power display button 328.

In the present embodiment, the number of the display lamps 329 is four. Four display lamps 329 are provided on the peripheral wall of the body end 325 to be exposed to the outside. When the user presses the power display button 328, the user can determine the remaining amount of the power supply device 32 by the number of lights emitted from the display lamp 329. Specifically, when the number of the lights emitted from the display lamp 329 is zero, it represents that the power supply device 32 is in short stock and cannot supply power to the electric tool 10 or other load devices; when the number of the lights emitted by the indicator light 329 is gradually increased from zero to four, the inventory of the power supply equipment 32 is gradually increased; when the number of the display lamps 329 lighted is four, it represents that the stock of the power supply device 32 tends to be saturated. It is to be understood that the number of the display lamps 329 is not particularly limited in the present application, and the number of the display lamps 329 may be one or more than one.
