[0024] With the development of technology, power tools are more and more widely used. Usually, power tools require users to operate with both hands. When changing the gear of a power tool, the user needs to hold the power tool with one hand and operate the button of the power tool with the other hand to shift gears.

[0025] However, in the face of some special scenarios, it is necessary to shift gears of the power tool with one hand. For example, when the user uses the power tool for high-altitude operations, for safety reasons, one hand is needed to assist in maintaining body balance, and the other hand is used to operate the power tool for work. Currently, the existing power tools shift gears through buttons and require the user to operate with both hands, which is not convenient for the user to use in scenarios where one-handed operation is required.

[0026] This application provides a control method and a power tool for a power tool, so that the user can hold and shift gears of the power tool with one hand, which is convenient for the user to use the power tool in scenarios where one-handed operation is required, and improves the safety of operating the power tool with one hand.

[0027] Please refer to Figure 1 , Figure 1 which is a schematic block diagram of a power tool provided by an embodiment of this application. Among them, the power tool 100 includes a motion measurement unit 110 and a controller 120, and the motion measurement unit 110 is connected to the controller 120.

[0028] In the embodiment of this application, after the power tool 100 is started, the motion measurement unit 110 is used to measure the motion state of the power tool 100 in a three-dimensional space. Among them, the motion measurement unit 110 includes at least one motion sensor to collect the linear acceleration, angular velocity, motion direction, etc. of the power tool 100 in real time, and generate corresponding motion measurement data and transmit it to the controller 120. Among them, the power tool 100 includes electric scissors, electric wire strippers, electric hole openers and other electric drive tools that can switch working gears.

[0029] In some embodiments, the motion measurement unit 110 may be composed of an accelerometer, a gyroscope and a magnetometer, which is not limited herein.

[0030] The embodiment of this application provides a control method for a power tool. The control method includes: receiving the motion measurement data of the motion measurement unit; judging whether the power tool meets a preset condition according to the motion measurement data; determining that the power tool meets the preset condition, and controlling the power tool to switch to a target working mode.

[0031] Next, in combination with Figure 1 specifically introduce a control method for a power tool provided by an embodiment of this application. Please refer to Figure 2 , which specifically includes the following steps:

[0032] Step S21: Receive the motion measurement data from the motion measurement unit.

[0033] In the embodiment of the present application, after the power tool is started, its controller can receive the motion measurement data transmitted by the motion measurement unit in real time. Among them, the motion measurement data includes the current linear acceleration, angular velocity, and motion direction of the power tool, etc. The controller can obtain the motion posture of the power tool according to the motion measurement data.

[0034] In some embodiments, the motion measurement unit can obtain the motion measurement data of the power tool according to a preset detection period and transmit it to the controller, or the controller samples the motion measurement data according to a preset sampling period to reduce the computational amount of judging the motion state of the power tool based on the motion measurement data in the subsequent process.

[0035] Step S22: Determine whether the power tool is triggered according to the motion measurement data.

[0036] In the embodiment of the present application, after obtaining the motion measurement data, the controller can detect whether the user currently triggers the power tool according to the motion measurement data, that is, this solution regards the operation of triggering the power tool as the gear shifting operation of the power tool, so that the power tool can be held and shifted with one hand; the power tool being triggered includes but is not limited to the power tool being shaken, the power tool vibrating or moving in an irregular manner, the power tool having abnormal movement, etc.

[0037] For example, the controller can extract the linear acceleration in the motion measurement data and determine whether the power tool is triggered by the user according to the linear acceleration. It can be understood that when the power tool is triggered, it has a certain linear acceleration. Therefore, a preset acceleration value can be preset in the controller, and when it is determined that the linear acceleration of the power tool is greater than the preset acceleration value, it is determined that the power tool is triggered.

[0038] Step S23: When it is determined that the power tool is triggered, detect whether the motion measurement data within a preset time meets the first preset condition.

[0039] In the embodiment of the present application, after the controller determines that the power tool is triggered, it further detects whether the motion measurement data within the preset time meets the first preset condition, that is, further determines whether the user needs to perform a gear shifting operation according to the first preset condition to avoid mis-shifting operations of the power tool.

[0040] In some embodiments, the above-mentioned first preset condition may be, for example, that the user holds the power tool and moves along a preset trajectory. For example, the movement trajectory may be a circular operation. The controller may determine that the user needs to shift gears after determining that the user holds the power tool and makes a circular motion within a preset time according to the motion measurement data. Alternatively, the first preset condition may also be a preset posture, which is not limited here.

[0041] Step S24: When it is determined that the motion measurement data within a preset time satisfies the first preset condition, control the power tool to switch to the target gear.

[0042] In the embodiments of the present application, after the controller determines that the motion measurement data within the preset time after being triggered satisfies the first preset condition, it controls the power tool to switch to the target gear. If the motion measurement data does not satisfy the first preset condition within the preset time, no gear shifting operation is performed to avoid accidental gear shifting of the power tool.

[0043] It can be understood that in the embodiments of the present application, by setting a motion measurement unit in the power tool, the motion measurement data of the power tool is obtained through the motion measurement unit. When it is detected that the user triggers the power tool according to the motion measurement data and the motion measurement data satisfies the first preset condition within a preset time, the power tool is controlled to switch to the target gear, so that the power tool can be held by the user with one hand and gear shifting operations can be performed, facilitating the use of the power tool by the user in scenarios where one-handed operation is required and improving the safety of one-handed operation of the power tool.

[0044] In some embodiments, the above-mentioned first preset condition includes that the power tool is triggered a first preset number of times. That is, after detecting the trigger, when the controller detects that the power tool is triggered a first preset number of times within a preset time, it controls the power tool to shift gears. For example, the first preset number of times may be 3 times, which is not limited here. The controlling the power tool to switch to the target gear in the above step S24 includes: controlling the power tool to switch to the next gear.

[0045] In some embodiments, the above-mentioned first preset condition includes that the number of times the power tool is triggered is within a preset number range. For example, the preset number range may be 3 to 5 times. The controlling the power tool to switch to the target gear in the above step S24 includes: controlling the power tool to switch to the next gear.

[0046] It can be understood that when the power tool includes a first gear, a second gear, and a third gear, it can be cycled to the next gear in the order of the gears, that is, the first gear switches to the second gear, the second gear switches to the third gear, and the third gear switches to the first gear.

[0047] Please refer to Figure 3 , Figure 3Schematic flowchart of the second control method for the power tool provided by the embodiment of the present application, which specifically includes the following steps:

[0048] Step S31: Receive the motion measurement data from the motion measurement unit.

[0049] Step S32: Determine whether the power tool is triggered according to the motion measurement data.

[0050] In the embodiment of the present application, steps S31 - S32 are the same as steps S21 - S22 above, and will not be elaborated here.

[0051] Step S33: When it is determined that the power tool is triggered, detect whether the number of times the power tool is triggered within the preset time is greater than or equal to the second preset number of times.

[0052] Step S34: When it is determined that the number of times the power tool is triggered within the preset time is greater than or equal to the second preset number of times and less than the third preset number of times, control the power tool to switch to the first gear.

[0053] Step S35: When it is determined that the number of times the power tool is triggered within the preset time is greater than the third preset number of times, control the power tool to switch to the second gear.

[0054] In the embodiment of the present application, the controller can also be pre - set with multiple number intervals, and each number interval corresponds to a gear. After the controller detects that the number of triggers falls into one of the number intervals according to the motion measurement data, it can control the power tool to switch to the gear corresponding to the number interval, so as to achieve the effect of quickly and accurately switching to the gear required by the user and improve the user experience.

[0055] Among them, the above - mentioned second preset number of times can be 3 times, and the third preset number of times can be 5 times, which is not limited. Moreover, the user can also set the above - mentioned second preset number of times and the third preset number of times to adjust to a comfortable number of times.

[0056] In some embodiments, the motion measurement data includes the motion direction, acceleration, angular velocity, and motion time. Please refer to Figure 4 , Figure 4 Schematic flowchart of a method for determining whether a power tool is triggered provided by the embodiment of the present application, which specifically includes the following steps:

[0057] Step S41: Obtain the motion force of the power tool according to the acceleration, angular velocity, and motion time.

[0058] Step S42: When it is determined that the motion direction is within the preset range and the motion force is greater than or equal to the preset value, determine that the power tool is triggered.

[0059] It can be understood that after receiving the motion measurement data, the controller can obtain the motion force of the power tool by using the acceleration, angular velocity, and motion time in the motion measurement data, and more accurately identify the triggering operation of the user on the power tool according to the motion force and motion direction. Among them, the greater the acceleration, the greater the motion force; the greater the angular velocity, the greater the motion force; and the shorter the motion time, the greater the motion force.

[0060] In the embodiment of the present application, after determining that the power tool is triggered, the corresponding motion direction can also be recorded as direction adjustment data. After the power tool successfully switches to the target gear, the preset range is adjusted according to the direction adjustment data. That is, the controller of the power tool can also execute a learning algorithm to automatically optimize the above-mentioned preset range to adapt to the influence brought by the aging of the power tool and the influence brought by the change of the use environment, so that the preset range for judging the motion direction always remains effective.

[0061] Moreover, after determining that the power tool is triggered, the corresponding acceleration, angular velocity, and / or motion time can also be recorded as force adjustment data. After the power tool successfully switches to the target gear, the preset value is adjusted according to the force adjustment data. That is, the controller of the power tool can also execute a learning algorithm to automatically optimize the above-mentioned preset value, so that the preset value for judging the motion force always remains effective.

[0062] Please refer to Figure 5 , Figure 5 which is a schematic flowchart of the control method for the third power tool provided by the embodiment of the present application, specifically including the following steps:

[0063] Step S51: Receive the motion measurement data of the motion measurement unit.

[0064] Step S52: Determine whether the power tool is triggered according to the motion measurement data.

[0065] Step S53: When it is determined that the power tool is triggered, detect whether the motion measurement data within the preset time meets the first preset condition.

[0066] Step S54: When it is determined that the motion measurement data within the preset time meets the first preset condition, control the power tool to switch to the target gear.

[0067] In the embodiment of the present application, the above steps S51 to S54 are the same as the above steps S21 to S24, and will not be elaborated here.

[0068] Step S55: When it is determined according to the motion measurement data that the trigger angle of the power tool exceeds the preset angle value, control the power tool to stop.

[0069] In an embodiment of the present application, the controller can also monitor the trigger angle of the power tool according to the motion measurement data. When it is determined that the trigger angle of the power tool exceeds a preset angle value, it is determined that the power tool has fallen or been thrown off, and then the power tool is controlled to stop.

[0070] In some embodiments, the motion measurement data includes the first-axis acceleration, the second-axis acceleration, and the third-axis acceleration. Please refer to Figure 6 , the above step S55 may specifically include the following steps:

[0071] Step S551: Calculate the comprehensive three-axis acceleration according to the first-axis acceleration, the second-axis acceleration, and the third-axis acceleration.

[0072] In an embodiment of the present application, the above first-axis acceleration may be the horizontal-axis acceleration of the horizontal plane, the second-axis acceleration may be the vertical-axis acceleration of the horizontal plane, and the third-axis acceleration may be the vertical acceleration.

[0073] Step S552: Record the number of times that the comprehensive three-axis acceleration continuously exceeds a preset acceleration value.

[0074] Step S553: When it is determined that the number of times reaches a fourth preset number of times, control the power tool to stop.

[0075] In an embodiment of the present application, when the controller determines that the comprehensive three-axis acceleration exceeds the preset acceleration value, it can determine that the power tool has been triggered. When the preset acceleration value is continuously exceeded up to the fourth preset number of times, it can be determined that the power tool has been thrown off or fallen.
