[0023] In a possible implementation, the control unit is further configured to control the lighting component to turn off when the duration that the trigger switch is in the first preset travel interval reaches a first preset duration.

[0024] In a possible implementation, the control unit is further configured to control the lighting component to turn off when the electric tool does not receive any operation and the motor stops working for a first preset time.

[0040] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0041] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0042] See Figures 1 to 3, is an electric tool provided by an embodiment of the present application, which includes at least two lighting modes and at least two action modes, and the electric tool also includes: a motor 1, configured to generate a driving force according to the selected action mode; a trigger switch 2, configured to be operated to drive the motor 1; a lighting component 3, configured to be activated according to the selected lighting mode; a forward and reverse switching lever 4, configured to be operable to be in a first position or a second position; a mode switching part 5 and a control part 6, the control part 6 is electrically connected to the mode switching part 5, the motor 1 and the lighting component 3, and the control part 6 is configured to: when the forward and reverse switching lever 4 is in the first position, respond to the user's first operation on the mode switching part 5 to select one of the lighting modes; when the forward and reverse switching lever 4 is in the second position, respond to the user's second operation on the mode switching part 5 to select one of the action modes.

[0043] It should be noted that the power tool also includes a housing, a spindle arranged inside the housing, the end of which is used to install the tool head, a battery pack arranged in the housing for providing power supply, and a gear transmission and impact mechanism 8 driven by the motor 1. The gear transmission and impact mechanism 8 can use the driving force of the motor 1 to form an impact on the spindle along the axial direction of the spindle, so that the spindle can drive the tool head to reciprocate.

[0044] In addition, the electric tool further comprises an electronic switch 9 , which comprises a switch accommodating box. The switch accommodating box contains an electronic switch for motor driving and an electronic switch for forward and reverse driving.

[0045] When the motor 1 is required to drive the impact mechanism 8, the trigger switch 2 is pressed, triggering the electronic switch in the electronic switch 9 for driving the motor 10, causing the control unit 6 to perform the corresponding operation. When the forward / reverse switching lever 4 is operated, the forward / reverse switching lever 4 triggers the electronic switch for forward / reverse driving. When the forward / reverse switching lever 4 is not in the neutral position, the electronic switch for forward / reverse driving transmits a corresponding forward or reverse signal to the control unit 6. When the forward / reverse switching lever 4 is not in the neutral position and the trigger switch 2 is pressed, the trigger switch 2 acts on the electronic switch for driving the motor 10. The electronic switch for driving the motor 10 transmits a signal to the control unit 6. The control unit 6 controls the forward or reverse rotation of the motor 10 based on the received motor drive signal and the forward or reverse signal, and adjusts the rotation speed of the motor 10 according to the amount of operation of the trigger switch 2. When the forward / reverse switching lever 4 is in the neutral position, the trigger switch 2 cannot be pressed or can only be pressed a small distance to power the control unit 6 or turn on the lighting component 3. In addition, in this embodiment, the trigger switch 2 (also called a trigger) can be set on the front side of the upper end of the handle of the power tool to facilitate the user to perform pressing operations, etc. when holding the handle.

[0046] Among them, the lighting mode may include an on mode, an off mode and a plurality of different brightness modes other than the on mode and the off mode. In one embodiment, the lighting mode may include: a 1-speed brightness mode, a 2-speed brightness mode, and an off mode, wherein the brightness corresponding to the 1-speed brightness mode may be less than the brightness corresponding to the 2-speed brightness mode. In another embodiment, the lighting mode may also include a 3-speed brightness mode, a 4-speed brightness mode, etc., wherein the brightness corresponding to the 3-speed brightness mode is greater than the brightness corresponding to the 2-speed brightness mode and less than the brightness corresponding to the 4-speed brightness mode. The action mode may include a first speed mode, a second speed mode, a third speed mode, a wood screw mode or a forward and reverse self-stop mode, etc., and the speeds corresponding to the first speed mode, the second speed mode and the third speed mode increase in sequence. Here, the brightness mode and the action mode do not only include the above-mentioned modes, but may also include other modes, which are not specifically limited here.

[0047] It should be noted that the first position includes the neutral position, and the second position includes the forward gear or the reverse gear. The setting of the neutral position and the forward gear or the reverse gear of the forward and reverse switching lever 4 can be referred to the prior art and will not be repeated here.

[0048] Here, as Figure 4 As shown, when the forward and reverse switching lever 4 is in the first position, the mode switching unit 5 responds to the user's first operation to select one of the at least two lighting modes. Figure 5 As shown, when the forward / reverse switching lever 4 is in the second position, the mode switching unit 5 responds to the second operation of the user to select one of the at least two operation modes.

[0049] In this embodiment, the first operation and / or the second operation performed on the mode switching unit 5 are the same. Here, the first operation and / or the second operation can specifically be a single press (i.e., a single click), a double press, a press for a set duration, etc. When the user inputs the first operation and / or the second operation to the mode switching unit 5, the control unit 6 can select the lighting mode or the action mode based on the change in the signal sent by the mode switching unit 5.

[0050] In this embodiment, when the above-mentioned mode is selected, the power tool is in standby mode, that is, the motor 1 is not driven at this time. This is to avoid sudden changes in the drive of the motor 1 when the mode is selected when the motor 1 is driven, avoid accidents, and improve the safety of operating the power tool.

[0051] In summary, in the electric tool provided by the above embodiment, when it is necessary to switch the lighting mode, it is only necessary to operate the forward and reverse switch lever 4 to the first position and perform the first operation on the mode switching part to select the desired lighting mode; and when it is necessary to switch the action mode, it is only necessary to operate the forward and reverse switch lever 4 to the second position and perform the second operation on the mode switching part 5 to select the desired action mode. That is, it is only necessary to operate the forward and reverse switch lever 4 to different positions to trigger the switching of the lighting mode and the action mode. There is no need to set a switching button separately for switching the lighting mode and the action mode, which can save space, reduce the volume and cost of the electric tool, and at the same time improve the convenience of mode switching.

[0052] In one embodiment, the electric tool further includes an operation panel 7 electrically connected to the control unit 6 . The operation panel 7 includes a main body 70 , and the mode switching unit 5 is disposed on the main body 70 .

[0053] like Figure 1 and Figure 3 As shown, the operation panel 7 can be provided on the sole of the power tool, and the operation panel 7 includes a main body 70, and the mode switching part 5 is provided on the main body 70, so that the user can perform the first operation or the second operation on the mode switching part 5 on the operation panel 7. By arranging the mode switching part 5 on the operation panel 7, it is convenient for the user to operate the mode switching part 5, and the space required is saved by the integrated arrangement. In an optional embodiment, the mode switching part 5 may not be provided on the operation panel 7, but may be provided directly on the power tool, for example, it may be provided on the handle below the trigger switch 2, and the operator can use one hand to simultaneously operate the mode switching part 5, the trigger switch 2 and the forward and reverse switching lever 4 in the area. In this way, the operator can use one hand to operate the power tool, which is more convenient to operate.

[0054] In one embodiment, the operation panel 7 further includes at least two light-emitting portions 71 provided on the main body 70 and used to indicate the lighting mode and / or the action mode; the control portion 6 is configured to indicate the selected lighting mode and / or action mode by lighting up the light-emitting portions 71 .

[0055] Specifically, the control unit 6 determines the selected lighting mode and / or action mode based on the position of the forward / reverse switching lever 4 and the first operation or the second operation obtained, and indicates the selected lighting mode and / or action mode by lighting the corresponding light-emitting portion 71. For example, when the forward / reverse switching lever 4 is in the first position, if the control unit 6 determines that the currently selected lighting mode is the 1st brightness mode based on the first operation input by the user to the mode switching unit 5, the light-emitting portion 71 corresponding to the 1st brightness mode will be illuminated; if the control unit 6 determines that the currently selected lighting mode is changed to the 2nd brightness mode based on the first operation input by the user to the mode switching unit 5, the light-emitting portion 71 corresponding to the 2nd brightness mode will be illuminated, and so on. For another example, when the forward / reverse switching lever 4 is in the second position, if the control unit 6 determines that the currently selected action mode is the wood screw mode based on the second operation input by the user to the mode switching unit 5, the light-emitting unit 71 corresponding to the wood screw mode is turned on; if the control unit 6 determines that the currently selected action mode is changed to the first speed mode based on the second operation continued to be input by the user to the mode switching unit 5, the light-emitting unit 71 corresponding to the first speed mode is turned on, and so on.

[0056] Among them, all the light-emitting parts 71 are arranged in a row, that is, all the light-emitting parts 71 are arranged in a straight line as a whole, which simplifies the design of the operation panel 7, makes the structure more compact and orderly, and further reduces the occupied space.

[0057] In this embodiment, the light-emitting unit 71 indicating the lighting mode and the action mode is shared, which makes the operation panel 7 more compact and reduces costs. To further enhance the compactness of the operation panel 7, in an optional embodiment, the light-emitting units 71 indicating the lighting mode and the action mode can be separate. That is, each lighting mode corresponds to a light-emitting unit 71, and each action mode also corresponds to another light-emitting unit 71. The number of light-emitting units 71 and the corresponding relationship between the modes are not specifically limited here and are subject to actual needs.

[0058] In one embodiment, the operation panel 7 further includes at least two identification portions 72 for identifying the lighting mode and / or the action mode; the identification portions 72 are disposed on the main body 70 and are disposed in one-to-one correspondence with the light-emitting portions 71 .

[0059] It can be understood that in order to facilitate the user to promptly and accurately know the lighting mode and / or action mode currently switched to, an identification portion 72 can be provided on the main body 70 of the operation panel 7 for each light-emitting portion 71, such as Figure 3 The numbers "1", "2", "3" and wood screw mode identifiers shown in the figure make the mode selection of the power tool clearer and help improve the user experience of the product.

[0060] In one embodiment, the operation panel 7 further includes a label 73 disposed on the main body 70 for identifying the function of the mode switching unit 5 . The label 73 at least covers a portion of the mode switching unit 5 .

[0061] like Figure 3 As shown, the character "MODE" and a light indicator can be used as label 73. In this embodiment, the provision of function label 73 facilitates the user's operation of the power tool to switch modes, thereby enhancing the user experience of the product. Furthermore, because label 73 at least partially covers the mode switching portion 5, the compactness of the operation panel is increased.

[0062] In one embodiment, the control unit 6 is further configured to control the lighting component 3 to operate according to the selected lighting mode, so that the user can perceive the selected lighting mode according to the brightness of the lighting component 3 when it is operating.

[0063] When the user switches lighting modes, the control unit 6 can control the lighting component 3 to operate in accordance with the selected lighting mode after the user performs a first operation on the mode switching unit to select a lighting mode. To facilitate user selection of the desired lighting mode, the control unit 6 can control the lighting component 3 to operate in accordance with the selected lighting mode. This allows the user to perceive the selected lighting mode based on the brightness of the lighting component 3 when operating. Furthermore, if the user performs a second first operation on the mode switching unit to change the selected lighting mode, the control unit 6 can control the lighting component 3 to operate in accordance with the currently selected lighting mode. This improves the lighting mode switching experience and enhances the user experience of the product.

[0064] In one embodiment, the control unit 6 is further configured to: when the trigger switch 2 is operated to the first preset travel range, control the lighting component 3 to operate according to the selected lighting mode; and when the trigger switch continues to be operated to the second preset travel range, control the motor 1 to generate driving force according to the selected action mode.

[0065] It should be noted that the power tool also includes an electronic switch electrically connected to the trigger switch 2. When the trigger switch 2 is pressed, the electronic switch will be triggered, and when the electronic switch is triggered, it will send an electronic signal to the control unit 6. The control unit 6 will control the lighting component 3 or the motor 1 to work accordingly.

[0066] Among them, when the forward and reverse switching lever 4 is in the neutral position, the user can only power on the control unit 6 by pressing the trigger switch 2. When the forward and reverse switching lever 4 is not in the neutral position, when the user presses the trigger switch 2 and operates the trigger switch 2 to the first preset travel range, the control unit 6 will be powered on first, and then the control unit 6 will control the lighting component 3 to work according to the selected lighting mode or according to the lighting mode memorized at the last power outage. Then, if the user presses the trigger switch 2 to the second preset travel range again, the control unit 6 will control the motor 1 to work according to the selected action mode. Here, the first preset travel range and the second preset travel range can be set separately according to actual needs. For example, the first preset travel range can be set to 1mm~1.4mm, etc., and the second preset travel range can be set to 1.4mm~2.0mm, etc.

[0067] In addition, the control unit 6 may be powered on when the battery pack is plugged into the power tool, but if the power tool does not work within a predetermined time, the control unit 6 is powered off. When the power tool is subsequently operated, the trigger switch 2 is pulled to power it on.

[0068] In one embodiment, the control unit 6 is further configured to control the lighting component 3 to continue operating in the selected lighting mode when the trigger switch 2 continues to be pressed to the second preset travel interval.

[0069] It can be understood that when the trigger switch 2 continues to be pressed to the second preset stroke interval, the control unit 6 will control the motor 1 to generate driving force according to the selected action mode, indicating that the power tool starts working at this time. In order to increase the ambient brightness in a relatively dark working environment to ensure that the operation using the power tool can be carried out normally, the control unit 6 can control the lighting component 3 to continue to work according to the selected lighting mode, thereby irradiating the outside of the power tool with light of a brightness that meets user requirements.

[0070] In one embodiment, the control unit 6 is further configured to: when the trigger switch 2 continues to be pressed to the second preset travel interval, respond to the user's third operation on the mode switching unit to select a lighting mode, and control the lighting component 3 to operate according to the selected lighting mode.

[0071] It can be understood that when the trigger switch 2 is pressed to the second preset stroke interval, the power tool starts working at this time. However, since the lighting mode previously selected by the user may not meet the needs of the current working environment, for example, the brightness corresponding to the previously selected lighting mode is too bright or too dark, the user may continue to switch the lighting mode based on demand. Therefore, after obtaining the user's third operation on the mode switching part 5 to select a lighting mode, the control unit 6 will control the lighting component 3 to work according to the selected lighting mode to achieve the switching of the lighting mode. It should be noted that the third operation can be the same as the first operation and / or the second operation, or it can be different from the first operation and / or the second operation. In this way, the required lighting mode can be selected based on demand when the power tool is working, which is convenient to operate and helps to improve the user experience of the product.

[0072] In one embodiment, the control unit 6 is further configured to control the lighting component 3 to turn off when the time duration that the trigger switch 2 is in the first preset travel interval reaches the first preset time duration.

[0073] Here, since the user may accidentally press the trigger switch 2 and the trigger switch 2 is pressed to the first preset travel range, the control unit 6 will control the lighting component 3 to operate according to the selected lighting mode. If the user does not discover or turn it off in time, the lighting component 3 may remain on for a long time and deplete the battery pack. Therefore, to avoid this situation, the control unit 6 will determine that the operation is caused by the user's accidental operation when the trigger switch 2 is in the first preset travel range for a period of time that reaches the first preset time, and will control the lighting component 3 to turn off. In this way, the battery pack can be effectively prevented from being depleted and the battery pack power can be conserved.

[0074] In one embodiment, the control unit 6 is further configured to control the lighting component 3 to turn off when the power tool does not receive any operation and the motor 1 stops working for a first preset time period.

[0075] Among them, when the power tool does not receive any operation and the motor 1 stops working for a first preset time, it means that the power tool has not been working for a long time. In order to avoid the battery pack being exhausted due to the lighting component 3 being kept on, the lighting component 3 can be controlled to turn off.

[0076] In one embodiment, the control unit 6 is further configured to control the lighting component 3 to always remain in the off state when the lighting mode is selected as the off mode.

[0077] Among them, when the user selects the lighting mode to be the off mode through the mode switching unit 5, it means that the user does not want or need the lighting component 3 to provide lighting, and the control unit 6 can control the lighting component 3 to always remain in the off state to meet the user's needs while saving power.

[0078] Based on the same inventive concept as the above-mentioned embodiments, the above-mentioned embodiments are described in detail below through a specific example. In this embodiment, the trigger switch is a switch trigger, the mode switching part is a mode switching button, the light-emitting part is an indicator light, the control part includes an MCU, and the lighting component includes a lighting lamp.

[0079] In this embodiment, the power tool has multiple action modes and multiple lighting modes, such as Figure 1 and Figure 3 As shown, this embodiment of the power tool features a forward / reverse switching lever 4 below the body, and an operating panel 7 located on the sole. The operating panel 7 includes a mode switching button 5 and four indicator lights. The four indicator lights sequentially indicate 1st speed, 2nd speed, 3rd speed, and wood screw mode. Furthermore, a button label 73 is located above the mode switching button 5 and has the words "MODE" and "Light" printed on it in sequence along the width of the operating panel.

[0080] First, pull the trigger to power on the MCU (also called pre-lighting; the battery pack supplies power to the MCU. When the trigger travel reaches the 1mm to 1.4mm range, the MCU powers on). The light illuminates at its brightest setting, and the operating mode is the one memorized from the last power outage. For example, if the operating mode was wood screw mode when the power was turned off, the indicator light indicating wood screw mode will illuminate upon powering on, indicating that the current operating mode is wood screw mode. Pulling the trigger will then activate the power tool in wood screw mode.

[0081] To switch the brightness of the light, operate the forward / reverse switch lever to the neutral position and then press the mode switch button to switch the lighting mode. To switch the motion mode, operate the forward / reverse switch lever to the forward or reverse position and then press the mode switch button to switch the motion mode.

[0082] When the lighting mode and action mode are selected, operate the switch trigger and make the switch trigger form the pre-lighting stroke, the lighting lamp will light up according to the selected lighting mode, and continue to pull the switch trigger to make the MCU control the motor to drive in the selected action mode.

[0083] Among them, the action mode may include: 3-speed mode + wood screw mode. Of course, in an optional embodiment, it can also be a 3-speed mode + forward and reverse self-stop mode, etc. The type of action mode is not specifically limited here. The lighting mode may include: brightest, bright, and off. Optionally, the lighting mode may also include four modes: brightest, bright, dark, and off, and may not include multiple different brightness modes of off. When the lighting mode is selected as the off mode, pulling the switch trigger will not turn on the light. In addition, in this embodiment, the operation mode switching button may include: single pressing, double-clicking, pressing for a predetermined time, etc. of the mode switching button. When the mode switching button is pressed once, when the MCU receives two change signals of "0-1" and "1-0" from the operation mode switching button, it indicates that the operation signal for the mode switching button has been received.

[0084] In this embodiment, the lighting mode may not be indicated by the indicator light on the operation panel, and the operator may perceive the selected lighting mode based on the brightness of the lighting lamp. In an optional embodiment, the indicator light of the action mode may be reused as the indicator light of the lighting mode.

[0085] Furthermore, in this embodiment, if no operation is performed on the power tool (including fully releasing the switch trigger, not switching modes, etc.), and the motor stops operating for more than 15 seconds, the light will be turned off. If the switch trigger remains within the pre-light range, the light will be turned off 10 minutes after being on.

[0086] The control process of the power tool in this embodiment is described below based on different scenarios.

[0087] Scenario 1: If the mode switch button is not operated to illuminate the light, pulling the switch trigger only powers on and starts the motor, and the light does not illuminate when power is on. Only after power is on and the motor is not operating, and the forward / reverse selector lever is switched to neutral, can the mode switch button be operated to turn the light on and change the light brightness. Subsequently, operating the switch trigger to drive the motor will cause the light to remain on. The light will be turned off after 15 seconds of no operation and the motor has stopped. Furthermore, if the switch trigger remains in pre-light mode for more than 10 minutes after the light is on, the light will be turned off.

[0088] Figure 6 A schematic diagram of a process of controlling a power tool according to an embodiment of the present invention, combined with Figure 6 As shown, the control method of the electric tool of this embodiment includes the following steps:

[0089] Step S10: Check whether the signal from the forward / reverse switching lever 4 is a neutral position signal. If so, proceed to step S20; otherwise, proceed to step S40. In this embodiment, since the trigger switch 2 cannot be pressed to the stroke that activates the motor 1 when the forward / reverse switching lever 4 is in the neutral position, the motor 1 cannot be activated. When the power is on and the motor 1 is not activated, the power tool is in a standby state.

[0090] Here, after being powered on, the MCU can detect in real time whether the signal of the forward / reverse switching lever is a neutral position signal, that is, whether the gear position of the forward / reverse switching lever is in the neutral position. If so, step S20 is executed, otherwise step S40 is executed.

[0091] Step S20 , detecting whether an operation signal of the mode switching button is received, if so, executing step S30 , otherwise returning to executing step S10 .

[0092] The operation signal may be a single-click operation signal, a double-click operation signal, etc., which is not specifically limited here.

[0093] Step S30: Switch the lighting mode and drive the lighting lamp to operate according to the selected lighting mode. In this embodiment, driving the lighting lamp to operate according to the selected lighting mode may include: operating the mode switch button to switch the lighting mode while driving the lighting lamp to operate according to the selected lighting mode. Alternatively, after operating the mode switch button to switch the lighting mode, the forward and reverse switching lever 4 is operated to a non-neutral position and then the trigger switch 2 is pulled to control the lighting lamp to operate according to the selected lighting mode. In an optional embodiment, the trigger switch 2 can also be pulled when the forward and reverse switching lever 4 is operated to the neutral position to control the lighting lamp to operate according to the selected lighting mode. Of course, in this case, the trigger switch 2 can only be pulled a small stroke and cannot be pulled to produce a stroke that causes the motor 1 to operate.

[0094] Here, since there may be only one or more operation signals received from the mode switching button, the lighting mode may be switched according to the number of operation signals received from the mode switching button.

[0095] Step S40: Check whether the device is in standby mode. If yes, go to step S50; otherwise, go back to step S10.

[0096] Here, when the MCU detects that the gear position of the forward / reverse switching lever 4 is not in the neutral position, it can detect whether the signal of the forward / reverse switching lever 4 is a non-neutral position signal. In addition, in this embodiment, detecting whether the motor is in the standby state, that is, detecting whether the motor 1 is operating, can generally be detected by detecting whether the motor is reversing, whether the current or voltage flowing through the motor exceeds a threshold, etc.

[0097] Step S50 , detecting whether an operation signal of the mode switching button is received, if so, executing step S60 , otherwise returning to executing step S10 .

[0098] Step S60: switch the action mode.

[0099] Here, since there may be only one or more operation signals received from the mode switching button, the action mode may be switched according to the number of operation signals received from the mode switching button.

[0100] Scenario 2: When the motor is in operation, that is, when the pressing stroke of the switch trigger exceeds the predetermined stroke, the operating mode switch button can turn the light on or off and switch the brightness of the light.

[0101] Figure 7 A schematic diagram of a process of controlling a power tool according to an embodiment of the present invention, combined with Figure 7 , to illustrate another control method of the electric tool in this embodiment, which includes the following steps:

[0102] Step S100: Detect whether the trigger switch 2 is pressed to a predetermined stroke. If so, proceed to step S200; otherwise, proceed to step S400. In this embodiment, the predetermined stroke is set to the stroke at which the motor starts to operate. In this step, detecting whether the trigger switch 2 is pressed to the predetermined stroke indicates that the MCU has driven the motor 1 to start operating, i.e., it is in a non-standby state.

[0103] Step S200 , detecting whether an operation signal of a mode switching button is received, if so, executing step S300 , otherwise returning to executing step S100 .

[0104] Step S300: switch the lighting mode and drive the lighting lamp to work according to the selected lighting mode.

[0105] Here, the lighting mode is switched directly according to the operation signal of the mode switching button, and the lighting lamp is driven to work according to the selected lighting mode without combining with the operation of other components such as the trigger switch.

[0106] Step S400: Check whether it is in standby state. If so, execute step S500; otherwise, return to execute step S100.

[0107] Step S500 , detecting whether an operation signal of a mode switching button is received, if so, executing step S600 , otherwise returning to executing step S100 .

[0108] Step S600: The lighting is turned off and the operation mode is switched.

[0109] In summary, in the power tool provided by this embodiment, when the forward / reverse switching lever is in the neutral position, the button can be operated to switch the lighting mode, and then the trigger switch can be operated to drive the light in the selected lighting mode. When the motor is in operation and the forward / reverse switching lever is not in the neutral position, the button can be operated to switch the lighting mode and drive the light in the selected lighting mode. This can reduce the size and cost of the power tool, improve accessibility to the sole of the power tool, and enhance the convenience of mode switching.
