Description

Electric tool and electric tool system

Technical Field

The application belongs to the field of electric tools, and particularly relates to an electric tool and an electric tool system.

Background

Along with the continuous increase of the automobile possession in China, automobile tools are also continuously enriched, and particularly, some emergency shelter tools, such as a starting power supply, an inflating pump, a jack and the like, become necessary tools for vehicle travel. The traditional electric tool can work only by plugging in electricity when in use, and the use environment is limited and the constraint is extremely inconvenient. Existing vehicles, devices, or electronic equipment are typically configured with a self-powered power source to power various components within. For example, an automobile battery is a device for supplying power to various electronic devices on an automobile. With the development of battery material technology, the capacity of batteries has been greatly improved, and the application range of batteries has been extended from some low-power electronic electric devices to some high-power electric devices, such as electric tools.

However, the battery performance of the existing electric tool is relatively single, i.e. the electric tool can only be used for supplying power to the electric tool, and when the electric tool is in an idle state (the electric tool does not need to work), the battery of the electric tool is in the idle state, so that the utilization rate of the battery of the electric tool is relatively low. If the battery is not used for a long time, the capacity and the service life of the battery are reduced, and the performance of the battery is further affected.

On the other hand, the wireless electric tool matched with the battery can only be used as an electric tool, and the function is quite single. And the cordless power tool needs to carry a battery in order to realize the power, so that the cordless power tool is quite heavy. The excessive weight and the relatively single function reduce the power of the user to purchase and carry the cordless power tool.

The embodiment of the application provides an electric tool, which comprises a shell and an operation assembly, wherein the shell is provided with a containing cavity and a combination part adjacent to the containing cavity, and the operation assembly is arranged in the containing cavity; the combination part is used for being connected with the combination end of power supply equipment with an automobile starting function, so that the operation assembly is electrically connected with the combination end of the power supply equipment to obtain electric energy from the power supply equipment.

The embodiment of the application also provides an electric tool system which comprises the electric tool and a power supply device with an automobile starting function, wherein the power supply device comprises a combination end, and a combination part of the electric tool is combined with the combination end of the power supply device.

According to the electric tool and the electric tool system provided by the embodiment of the application, the power supply equipment with the automobile starting function is adopted to supply power for the electric tool, so that a special power supply is not required to be arranged for the electric tool, the production cost is reduced, and the portability of the electric tool is also improved.

Thus, the controller 121 controls the driving member 122 to drive the operation head 123 to rotate, so as to realize the function of the electric tool.

Alternatively, in other embodiments, the operating head 123 may be coupled to the driving member 122 outside the receiving cavity 110.

Optionally, in one embodiment, the operating assembly 12 further includes a circuit board 124. The circuit board 124 is also disposed within the receiving cavity 110 and is located on a side of the driver 122 adjacent the power device 32.

It will be appreciated that the connection between the power input interface 125 and the controller 121 may be a direct connection or an indirect connection. When the power input interface 125 is indirectly connected to the controller 121, a control switch or the like may be further connected between the power input interface 125 and the controller 121, which is not limited herein.

Further, in one embodiment, the controller 121 receives a communication signal through the first communication port 1255 and controls the operating state of the power tool 10 in response to the communication signal.

For example, the controller 121 obtains a specific parameter value of the power supply device 32 through the first communication port 1255, and the controller 121 determines whether to operate according to the parameter value. Or the controller 121 obtains the state of the power supply device 32 through the first communication port 1255, controls the operation if it is normal, and controls the non-operation if it is abnormal.

Specifically, taking the temperature signal as an example, when the power tool 10 is powered at too high a temperature and there is a risk of being burned out, the controller 121 sends a control signal to the power device 32 through the first communication port 1255 to control the power device 32 to stop powering the power tool 10 until the temperature of the power tool 10 is reduced to meet the requirement, so that the power tool 10 is prevented from being burned out during charging, and the service life of the power tool 10 is greatly prolonged. Of course, a heat dissipation fan may also be disposed in the electric tool 10, and when the temperature of the electric tool 10 is too high and the electric tool 10 is at risk of burning out when the power supply device 32 supplies power to the electric tool 10, the temperature signal controls the heat dissipation fan to start so as to dissipate heat of the electric tool 10.

In the following, a voltage signal is taken as an example, when the voltage or current is too high when the electric tool 10 is powered, the controller 121 sends a control signal to the power supply device 32 through the first communication port 1255 to control the power supply device 32 to stop powering the electric tool 10 and send out an alarm, so as to avoid the influence of overvoltage or overcurrent on the electric tool 10.

Further, referring to fig. 6 and 7, the power supply device 32 will be described in detail below. The power supply device 32 comprises a power supply output interface 321. When the power supply device 32 is connected to the power tool 10, the power input interface 125 is electrically connected to the power output interface 321, and the power supply device 32 supplies power to the power tool 10 through the power output interface 321. Thus, the power supply device 32 can supply driving energy for the rotation of the operation head 123. And when the power supply device 32 is not connected with the electric tool 10 any more, the power supply device 32 can serve as a mobile power supply to charge the external device through the power supply output interface 321, or the power supply output interface of the power supply device 32 can also be connected with the storage battery through the battery clamp to output current to assist the storage battery in starting the automobile.

In this embodiment, the power input interfaces 125 and the power output interfaces 321 are in one-to-one correspondence, and the number of the two interfaces is one. It will be appreciated that the power input interfaces 125 and the power output interfaces 321 may not be in one-to-one correspondence, i.e., the number of power input interfaces 125 is greater than or less than the number of power output interfaces 321. It should be understood that the present application is not limited to the number of the power input interfaces 125 and the power output interfaces 321, and may be one or more.

Optionally, the power input interface 125 and the power output interface 321 may be selected from various interfaces such as CP 3500. The application is not limited to the type of power input interface 125 and power output interface 321.

Alternatively, the power input interface 125 of the power tool 10 may be the same type of interface as the input interface of the battery clamp, so that the power device 32 may power the power tool 10 or assist in vehicle start-up through the same power output interface 321.

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 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 power tool 10 and the power device 32, through which the power device 32 supplies power to the power tool 10. The connection of 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, through which the power supply device 32 outputs various signals to the power tool 10. The signal may be, but is not limited to, a temperature signal, a cell over temperature signal, or a low voltage energy protection signal, etc. Taking the temperature signal as an example for illustration, when the power supply device 32 supplies power to the electric tool 10 at too high a temperature so that the power supply device 32 has a burnout risk, 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 burnout when supplying power to the electric tool 10, and the service life of the power supply device 32 is greatly prolonged. Of course, a cooling fan (not shown) may be disposed in the electric tool 10, and the temperature signal controls the cooling fan to start to cool the power supply device 32 when the power supply device 32 supplies power to the electric tool 10 at too high a temperature so that the power supply device 32 is at risk of burning.

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

It will be appreciated 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 this 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 shapes of the first groove 3201 and the second groove 3202 are different, and/or the inner diameters of the first groove 3201 and the second groove 3202 are different; 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 intervals 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 with the first power input interface 1251 and the second power output interface 3212 is connected with the second power input interface 1253, so that the power supply of the power supply device 32 to the power tool 10 is prevented from being stopped due to short circuit, the power supply device 32 is prevented from being burnt due to short circuit, and the service life of the power supply device 32 is prolonged. In addition, the second power output interface 3212 and the second communication port 3213 are arranged in the second groove 3202 at intervals, and have different shapes and/or different inner diameters, so that the fool-proofing function can be achieved, the situation that the first power input interface 1251 of the electric tool 10 is connected with the second power output interface 3212 of the power supply device 32 and the second power input interface 1253 of the electric tool 10 is connected with the first power output interface 3211 of the power supply device 32 is avoided, and the safety of the electric tool 10 in use is improved. It is understood that the second communication port 3213 may be disposed in the first recess 3201, and the second communication port 3213 and the first power output port 3211 are disposed at a distance in the first recess 3201.

In the present embodiment, the charging interface 327 is provided on an end surface of the coupling end 320. It will be appreciated that the charging interface 327 may also be provided on the end surface of the body end 325 facing away from the coupling end 320 or at other locations, as the application is not limited in this regard.

As shown in fig. 6 and 7, the power supply device 32 is optionally further provided with an electricity quantity display key 328 and at least one display lamp 329 provided on the peripheral surface of the main body end 325.

Thus, the user can judge whether the stock of the power supply device 32 is sufficient by observing whether the display lamp 329 emits light or not, and the display lamp is intuitive and convenient and easy to observe. Or the power display button 328 and the display lamp 329 may be connected to a controller that controls the light emitting state of the display lamp 329 based on the condition of the power in the power supply apparatus 32 in response to a pressing signal of the power display button 328.

In the present embodiment, the number of display lamps 329 is four. Four display lamps 329 are provided on the peripheral wall of the body end 325 to be exposed. When the user presses the power display button 328, the user can determine the stock of the power supply device 32 by the number of lights emitted from the display lamp 329.
