[0039] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0040] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.
[0041] It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if" as used herein may be interpreted as "at the time of," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the described features, steps, operations, elements, components, items, types, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or" and "and / or" as used herein are to be interpreted as inclusive, meaning any one or any combination. Thus, “A, B, or C” or “A, B, and / or C” means “any of: A; B; C; A and B; A and C; B and C; A, B, and C.” An exception to this definition occurs only when a combination of elements, functions, steps, or operations are inherently mutually exclusive in some manner.
[0042] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows.

Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.
[0043] 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.
[0044] 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.
[0045] Power tools, especially handheld power tools, such as impact wrenches, impact drivers, electric drills, and angle grinders, are commonly used in indoor and outdoor applications such as furniture installation and repair, wall treatment, plumbing and electrical renovation, metal treatment, wood processing, auto repair, or railway maintenance. For example, when assembling furniture, repairing tables and chairs, doors and windows, or performing plumbing and electrical renovations, electric drills are used to drill holes and impact drivers are used to remove and install screws; when performing auto or railway maintenance, impact wrenches are used to remove and install nuts; when performing metal treatment or wood processing, angle grinders are used to polish or cut metal or wood surfaces. When using power tools in these scenarios, additional lighting is required due to factors such as the dark indoor environment or outdoor work at night.
[0046] Power tools in the prior art are usually provided with a lighting lamp to provide illumination for the operator in a work scene requiring illumination, but the lighting lamps of existing power tools usually have only one brightness level.
[0047] Different ambient brightness levels also require different lighting brightness levels. For example, in brighter environments, the lighting brightness can be set lower or even turned off; in darker environments, the lighting brightness needs to be higher. Furthermore, even in the same ambient brightness, metal processing requires a lower lighting brightness than wood processing, as metal surfaces reflect light much more than wood. Clearly, a single lighting level is currently insufficient to meet the needs of diverse environments and working conditions.
[0048] To solve the above problems, in the prior art, an action mode switch is usually set on the power tool to switch the action mode, and a lighting brightness switch button is set to switch between different brightness modes of the lighting lamp, which solves the problem that the brightness of a single lighting lamp of the power tool cannot adapt to the needs of multiple working conditions and multiple environments.
[0049] However, the aforementioned solution requires an additional light brightness switch button, which increases the size of the power tool, hindering its miniaturization and increasing its production cost. Therefore, there is an urgent need to develop a compact, low-cost power tool that allows for easy switching of the light and operating modes.
[0050] Based on this, an embodiment of the present application provides an electric tool, which includes at least two action modes. Referring to Figure 1 and in combination with Figure 2, the electric tool includes a motor 2, which is configured to generate driving force according to the selected action mode. Specifically, the motor 2 is arranged in a housing 1, and the housing 1 includes a body housing 101, a handle housing 102 and a battery pack receiving housing 103. Among them, the motor 2 is arranged in the body housing 101 to provide driving force for the electric tool. In some embodiments, the motor 2 can be a brushed motor, a brushless motor or other types, which is not limited in this application, and will be described below using a three-phase brushless motor as an example.
[0051] In some embodiments, the action modes may include a first speed mode, a second speed mode, a third speed mode, a wood screw mode, or a forward / reverse self-stop mode, wherein the speeds corresponding to the first speed mode, the second speed mode, and the third speed mode increase in sequence. Before the motor 2 is driven, one of at least two action modes may be selected as the operating mode of the power tool. Since the power tool has at least two selectable action modes, the power tool can be used in multiple scenarios.
[0052] Continuing with FIG. 1 and in conjunction with FIG. 3 , the power tool includes at least two lighting modes and a lighting component 6 configured to be activated according to a selected lighting mode. The lighting modes correspond to different brightness states of the lighting component 6 , and the lighting component 6 is configured to be activated according to the selected lighting mode. In this embodiment, the lighting modes may include an on mode, an off mode, and brightness modes other than the on mode and the off mode.
[0053] There may be one or more brightness modes other than the on mode and the off mode. When there is one brightness mode other than the on mode and the off mode, the brightness corresponding to the brightness mode other than the on mode and the off mode is different from the brightness corresponding to the on mode. In this embodiment, the brightness corresponding to the brightness mode other than the on mode and the off mode is lower than the brightness corresponding to the on mode. In an alternative embodiment, the brightness corresponding to the brightness mode other than the on mode and the off mode is higher than the brightness corresponding to the on mode. The specific embodiment is not limited thereto.
[0054] When there are multiple brightness modes other than the on mode and the off mode, the multiple different brightness modes include: a 1-level brightness mode and a 2-level brightness mode, wherein the brightness corresponding to the 1-level brightness mode may be less than the brightness corresponding to the 2-level brightness mode, and the brightness corresponding to the on mode is the highest. In some embodiments, the lighting mode may further include a 3-level brightness mode and a 4-level brightness mode, wherein the brightness corresponding to the 3-level brightness mode is greater than the brightness corresponding to the 2-level brightness mode and less than the brightness corresponding to the 4-level brightness mode, and the brightness corresponding to the on mode is the highest.
[0055] In this embodiment, the lighting component 6 is arranged at the front of the body shell 101 and is arranged around the output shaft 5. The lighting component 6 includes a light board 601, at least two lighting lamps 602, a lampshade 603 and a rubber cover 604. In this embodiment, the light board 601 is a ring-shaped PCB board, and the lighting lamps 602 are installed around the light board 601. In some embodiments, the light board 601 is a PCB board assembly composed of a plurality of short PCB boards, wherein a lighting lamp 602 is provided on each PCB board, and adjacent PCB boards are connected by wires. In some embodiments, the lampshade 603 is made of transparent material, and the lighting lamp 602 is installed in the lampshade 603. The light emitted by the lighting lamp 602 shines through the lampshade 603 and illuminates the front of the power tool. In some embodiments, the light board 601 is installed on the body shell 101, rather than in the lampshade 602, and the specific details are not limited.
[0056] In some embodiments, the rubber cover 604 is provided radially outward of the lampshade 603. The rubber cover 604 is made of elastic material to act as a buffer to prevent damage to the lighting lamp 602. In some embodiments, the rubber cover 604 also has a light shielding function to prevent light emitted by the lighting lamp 602 from escaping radially outward from the output shaft 5.
[0057] In some embodiments, the lighting component 6 may also be disposed near the intersection of the handle housing 102 and the body housing 101. In some embodiments, the lighting component 6 may also be disposed on the battery pack receiving housing 103. The specific arrangement and structure of the lighting component 6 are not specifically limited herein.
[0058] In some embodiments, the lighting component 6 may also include only a lighting lamp 602, which can be installed at any position of the shell 1 and can be installed on the shell 1 in any way, such as directly snapping onto the mounting mechanism on the shell 1. There is no specific limitation and it is subject to actual needs.
[0059] Continuing with Figures 1 and 2 , the power tool further includes a trigger switch 7, which is operated to drive the motor 2. When the operator operates the trigger switch 7, the power tool generates a motor drive signal and drives the motor 2 to rotate based on the motor drive signal. The trigger switch 7 can include a trigger, a switch button, or a push-to-twist switch.
[0060] In some embodiments, when the trigger switch 7 is a trigger, the trigger switch 7 is mounted on the handle housing 102 and is located below the body housing 101. The operator can hold the handle housing 102 and pull the trigger with the index finger to drive the motor 2 to rotate.
[0061] In some embodiments, when the trigger switch 7 is a switch button, the switch button can be set at any position of the body shell 101, the handle shell 102 or the battery pack receiving shell 103, and the operator can drive the motor 2 to rotate by pressing the switch button.
[0062] In some embodiments, when the trigger switch 7 is a push button switch, the push button switch can be set at any position of the body shell 101, the handle shell 102 or the battery pack receiving shell 103. The push button switch can include at least two positions of "on" and "off". The operator can drive the motor 2 to rotate by pushing the push button switch from the "off" position to the "on" position.
[0063] Continuing with Figures 1 and 2 , the power tool includes a forward / reverse switching lever 8 . Specifically, the forward / reverse switching lever 8 is operable by the operator to switch the motor 2 in forward / reverse direction. The forward / reverse switching lever 8 is mounted on the handle housing 102 and positioned above the trigger switch 7 . In some embodiments, the forward / reverse switching lever 8 and the trigger switch 7 are located within the operator's one-handed reach, facilitating single-handed operation.
[0064] The forward / reverse switching lever 8 is configured to be operable in a first position or a second position. As shown in FIG4 , the first position includes a neutral position. When the forward / reverse switching lever 8 is in the neutral position, the trigger switch 7 cannot be operated to drive the motor 2. As shown in FIG5 , the second position includes a forward gear position or a reverse gear position. When the forward / reverse switching lever 8 is in the forward gear position, the motor 2 is driven to rotate forward; when the forward / reverse switching lever 8 is in the reverse gear position, the motor 2 is driven to rotate reverse. Regarding the neutral position of the forward / reverse switching lever 8 and the setting of the forward gear position or the reverse gear position, reference can be made to the prior art and will not be repeated here.
[0065] In some embodiments, as shown in FIG2 , the power tool includes an electronic switch module 9, which includes a switch housing box and at least one electronic switch housed in the switch housing box. The electronic switch includes a first electronic switch for driving the motor 2 and a second electronic switch for switching the motor's forward and reverse rotation. Specifically, the operator operates the trigger switch 7 to trigger the first electronic switch to generate a motor drive signal, and the power tool drives the motor 2 to rotate based on the motor drive signal. Alternatively, the operator operates the forward and reverse switching lever 8 to trigger the second electronic switch to generate a forward rotation signal or a reverse rotation signal, and the power tool controls the forward or reverse rotation of the motor 2 based on the forward rotation signal or the reverse rotation signal.
[0066] Specifically, when the motor 2 is required to operate, the forward / reverse switching lever 8 is first operated to a non-neutral position, for example, when the forward / reverse switching lever 8 is in the forward gear, triggering the second electronic switch to generate a forward signal. When the forward / reverse switching lever 8 is in the reverse gear, the second electronic switch generates a reverse signal. The trigger switch 7 is then operated to trigger the first electronic switch to generate a motor drive signal. The power tool controls the forward or reverse rotation of the motor 2 based on the motor drive signal and the forward or reverse signal.
[0067] As shown in FIG1 , the power tool provided herein includes a mode switching unit 10 . The mode switching unit 10 is configured to generate a mode switching signal in response to an operator's operation. The mode switching unit 10 is operable by the operator, and the mode switching signal is an electrical signal used to instruct the power tool. The power tool switches between operating modes and / or lighting modes in response to the mode switching signal generated by the mode switching unit 10.
[0068] In some embodiments, the mode switching unit 10 may be disposed on the housing 1 of the power tool, such as the body shell 101 of the housing 1, to facilitate user operation.
[0069] In some embodiments, the mode switching unit 10 includes at least one of a button, a dial, and a knob.
[0070] When the mode switching unit 10 is a button, the mode switching can be achieved through a single button operation mode or a combination of multiple button operation modes, and the button operation modes may include single button operation, multiple button operation, short press, long press, etc. For example, the user can press the button once to switch the mode, or press the button for more than 5 seconds to switch the mode.
[0071] When the mode switching portion 10 is a dial knob, the mode switching can be achieved through a single dial knob operation mode or a combination of multiple dial knob operation modes, and the dial knob operation modes include at least single dialing, unidirectional dialing, multiple dialing, multi-directional dialing, etc. For example, the dial knob has positions A, B, and C. If the current power tool dial knob is in position B, the mode can be switched by dialing it once toward position A, or by dialing it once toward position A and then back to position B to switch the mode.
[0072] When the mode switching part 10 is a knob, the knob can be provided with a plurality of rotation gears, each rotation gear corresponding to a braking mode of the power tool, and the braking mode can be switched by rotating the knob to the rotation gear corresponding to the desired braking mode.
[0073] Switching the mode of the power tool by using buttons, dials, knobs, etc. is convenient for users to operate and can improve the convenience of switching the braking mode. The following describes the implementation of this embodiment using the mode switching part 10 as a button.
[0074] Continuing to refer to FIG. 2 , the electric tool includes a control unit 11 , which is housed in a battery pack receiving housing 103 . In some embodiments, the control unit 11 is housed in a handle housing 102 .
[0075] The control unit 11 is electrically connected to the motor 2, the electronic switch 9, and the lighting unit 6. Specifically, the control unit 11 includes a control board, a microprocessor (MCU) integrated on the control board, a motor drive circuit, capacitors, and other components. The motor drive circuit is composed of multiple power switching elements (typically MOSFETs or IGBTs). By turning the power switching elements on and off to switch the direction and magnitude of the current, the motor controls the speed and torque of the three-phase motor.
[0076] The control unit 11 controls the motor 2 to rotate forward or reverse according to the received motor driving signal and the forward or reverse signal, and adjusts the rotation speed of the motor 2 according to the operation amount of the trigger switch 7.
[0077] In this embodiment, when the forward / reverse switching lever 8 is in the first position, the control unit 11 responds to the user's first operation on the mode switching unit 10 to select a lighting mode; when the forward / reverse switching lever 8 is in the second position, the control unit 11 responds to the user's second operation on the mode switching unit 10 to select an action mode.
[0078] It should be noted that, as shown in FIG4 , when the forward / reverse switching lever 8 is in the first position, the mode switching unit 10 responds to a first user operation to select a lighting mode from at least two lighting modes. As shown in FIG5 , when the forward / reverse switching lever 8 is in the second position, the mode switching unit 10 responds to a second user operation to select an action mode from at least two action modes.
[0079] In some embodiments, the first operation and / or the second operation performed on the mode switching unit 10 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 10, the control unit 11 can select the lighting mode or the action mode based on the change in the signal sent by the mode switching unit 10.
[0080] In this embodiment, when the above-mentioned mode is selected, the power tool is in standby mode, that is, the motor 2 is not driven at this time. This is to avoid sudden changes in the drive of the motor 2 when the mode is selected when the motor 2 is driven, avoid accidents, and improve the safety of operating the power tool.
[0081] In some embodiments, the control unit 11 controls the lighting component 6 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 6 when it is operating.
[0082] When the user switches lighting modes, the control unit 11 can control the lighting component 6 to operate in accordance with the selected lighting mode after the user performs a first operation on the mode switching unit 10 to select a lighting mode. To facilitate user selection of the desired lighting mode, the control unit 11 can control the lighting component 6 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 6 when operating. Furthermore, if the user performs a first operation on the mode switching unit 10 again to change the selected lighting mode, the control unit 11 can control the lighting component 6 to operate in accordance with the currently selected lighting mode. This improves the user experience when switching lighting modes and contributes to an enhanced user experience.
[0083] Specifically, when the forward and reverse switching lever 8 is in the neutral position, the operator operates the mode switching part 10 to select the off mode, and the lighting component 6 remains closed; when the 1st level brightness mode, the 2nd level brightness mode or the on mode is selected, the lighting component 6 is turned on with the brightness of the lighting lamp corresponding to each level, so that the operator can clearly and intuitively perceive the selected lighting mode.
[0084] In some embodiments, the control unit 11 controls the lighting component 6 to operate in the selected lighting mode for a preset time and then extinguish. This prevents the power tool from being idle for an extended period of time after the lighting mode is selected, which could result in reduced battery life. The preset time is 10 seconds. Furthermore, if the trigger switch 7 is operated to activate the motor 2 within the preset time after the lighting mode is selected, the control unit 11 controls the lighting component 6 to continue operating at the brightness corresponding to the currently selected lighting mode.
[0085] In some embodiments, the control unit 11 controls the lighting unit 6 to operate and maintain the selected lighting mode. Since the lighting unit 6 remains in operation after the lighting mode is selected, the operator can first use the lighting unit 6 to illuminate the work environment, install the work head, and align the workpiece with the work head, and then operate the trigger switch 7 to drive the motor. This avoids the need to operate the trigger switch 7 to turn the lighting unit 6 back on after it turns off, saving time and improving the working experience.
[0086] In one embodiment, when the trigger switch 7 is operated to a first preset travel range, the control unit 11 controls the lighting component 6 to operate in the selected lighting mode. When the trigger switch 7 is further operated to a second preset travel range, the control unit 11 controls the motor 2 to generate driving force in the selected operation mode. Thus, when the operator does not need to operate the motor 2 but only requires illumination, they can operate the trigger switch 7 to and maintain it in the first preset travel range, at which point the power tool functions solely as a lighting tool. To operate the motor 2, the operator can continue to operate the trigger switch 7 until it is in the second preset travel range.
[0087] When the forward / reverse switching lever 8 is in the neutral position, the user pressing the trigger switch 7 only powers up the control unit 11. However, when the forward / reverse switching lever 8 is not in the neutral position, pressing the trigger switch 7 and operating it to the first preset travel range will first power up the control unit 11. The control unit 11 then controls the lighting component 6 to operate in the selected lighting mode or the lighting mode memorized from the last power outage. This avoids repeated lighting mode selection during power tool use, making operation more convenient and saving time.
[0088] Then, if the user presses the trigger switch 7 to the second preset stroke range, the control unit 11 will control the motor 2 to operate according to the selected operation mode. Here, the first preset stroke range and the second preset stroke range can be set according to actual needs. For example, the first preset stroke range can be set to 1mm to 1.4mm, and the second preset stroke range can be set to 1.4mm to 2.0mm.
[0089] In some embodiments, when the battery pack is plugged into the power tool, the control unit 11 is powered on simultaneously. If the power tool does not operate within a predetermined time, the control unit is powered off. When the power tool is subsequently operated, the trigger switch 7 is pulled to power it on again.
[0090] In some embodiments, when the trigger switch 7 continues to be pressed to the second preset stroke interval, the control unit 11 controls the lighting component 6 to continue to operate according to the selected lighting mode.
[0091] It can be understood that when the trigger switch 7 continues to be pressed to the second preset stroke interval, the control unit 11 will control the motor 2 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 11 can control the lighting component 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.
[0092] In some embodiments, when the trigger switch 7 continues to be pressed to the second preset stroke interval, the control unit 11 responds to the user's third operation on the mode switching unit 10 to select a lighting mode and controls the lighting component 6 to operate according to the selected lighting mode.
[0093] It is understood that when the trigger switch 7 is pressed to the second preset travel range, the power tool begins operation. However, because 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 dim, the user may continue to switch lighting modes based on their needs. Therefore, after receiving the user's third operation on the mode switching unit 10 to select a lighting mode, the control unit 11 controls the lighting component 6 to operate according to the selected lighting mode to achieve the switching of the lighting modes.
[0094] It should be noted that the third operation may be the same as or different from the first operation and / or the second operation. In this way, the desired lighting mode can be selected based on needs when the power tool is working, which is convenient and helps to improve the user experience of the product.
[0095] In some embodiments, when the time duration during which the trigger switch 7 is within the first preset travel interval reaches the first preset time duration, the control unit 11 controls the lighting component 6 to turn off.
[0096] Here, since the user may accidentally press the trigger switch 7 and the trigger switch 7 is pressed to the first preset travel range, the control unit 11 will control the lighting component 6 to operate according to the selected lighting mode. If the user does not discover or turn it off in time, the lighting component 6 may remain on for a long time and deplete the battery pack. Therefore, to avoid this situation, the control unit 11 will determine that the operation is caused by the user's accidental operation when the trigger switch 7 has been in the first preset travel range for a period of time that reaches the first preset time, and will control the lighting component 6 to turn off. In this way, the battery pack can be effectively prevented from being depleted and the battery pack power can be conserved.
[0097] In some embodiments, when the electric tool does not receive any operation and the motor 2 stops working for a first preset time period, the control unit 11 controls the lighting component 6 to turn off.
[0098] Among them, when the power tool does not receive any operation and the motor 2 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 6 being kept on, the lighting component 6 can be controlled to turn off.
[0099] In some embodiments, when the lighting mode is selected as the off mode, the control unit 11 controls the lighting component 6 to always remain in the off state.
[0100] Among them, when the user selects the lighting mode to be the off mode through the mode switching unit 10, it means that the user does not want or need the lighting component 6 to provide lighting, and the control unit 11 can control the lighting component 6 to always remain in the off state to meet the user's needs while saving power.
[0101] In summary, in the power tool provided in this embodiment, when it is necessary to switch the lighting mode, it is only necessary to operate the forward and reverse switch lever 8 to the first position, and perform the first operation on the mode switching part 10 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 8 to the second position, and perform the second operation on the mode switching part 10 to select the desired action mode. That is, it is only necessary to operate the forward and reverse switch lever 8 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 power tool, and at the same time improve the convenience of switching the lighting mode and the action mode.
[0102] Furthermore, in this embodiment, the power tool is powered by a battery pack. When the power tool is powered by a battery pack, the battery pack can be fixedly mounted inside or outside the power tool, or it can be removably mounted to the power tool. For example, as shown in FIG1 , the battery pack can be removably mounted to a battery pack receiving housing 103 to achieve mechanical and electrical connection with the power tool. In some embodiments, the power tool can also be powered by an AC power source.
[0103] The battery pack 101 can be of different specifications, such as 12V, 16V, 18V, 20V, 56V, 60V, and 80V, and can have different capacities, such as 2Ah, 4Ah, 5Ah, 6Ah, 8Ah, 11Ah, and 20Ah. The number of battery packs 101 can be one, two, or more. That is, the installation method and location of the battery pack, as well as the type, specifications, capacity, and quantity of the battery pack can be determined based on the requirements of different power tools, and this application does not impose any restrictions on this.
[0104] In some embodiments, as shown in FIG3 , the power tool further includes a gear transmission mechanism 3 , which is connected to the motor 2 and is configured to receive and convert torque from the motor 2 . The gear transmission mechanism 3 includes a sun gear 301 , a planetary carrier, a planetary gear set, and an inner ring gear 303 . The planetary gear set comprises a plurality of planetary gears 302 , which are supported on the planetary carrier and meshed between the sun gear 301 and the inner ring gear 303 . The motor 2 drives the sun gear 301 to rotate, thereby driving the planetary gears 302 to rotate. The inner ring gear 303 has internal teeth that mesh with the planetary gears 302 . The inner ring gear 303 is fixed to the body housing 101 and cannot rotate relative to the body housing 101 .
[0105] In some embodiments, the power tool further includes an impact mechanism 4 and an output shaft 5. The impact mechanism 4 is connected to the gear transmission mechanism 3 and is driven by the gear transmission mechanism 3 to drive the output shaft 5 to rotate. The output shaft 5 is at least partially disposed within the body housing 101, and the end portion is used to mount a tool head. The motor 2 drives the gear transmission mechanism 3 to drive the impact mechanism 4 to rotate the output shaft 5 and apply radial impact to the output shaft 5 when the load is large. The impact mechanism 4 may include a conventional hammer mechanism using a spring, or may include an oil pressure impact unit, and the specific details are not limited thereto. In addition, the working head may include a bit for removing screws, or may include a socket assembly for removing nuts.
[0106] In addition, to facilitate operation and compact integration, as shown in Figures 1 and 3, in some embodiments, the power tool also includes an operation panel 12, which is electrically connected to the control unit 11. The operation panel 12 includes a main body 121, and the mode switching unit 10 is arranged on the main body 121.
[0107] Specifically, the operation panel 12 is provided on the battery pack receiving shell 103, and the operation panel 12 includes a main body 121. The mode switching part 10 is provided on the main body 121, so that the user can perform the first operation or the second operation on the mode switching part 10 on the operation panel 12. By arranging the mode switching part 10 on the operation panel 12, it is convenient for the user to operate the mode switching part 10, and the required space is saved through the integrated arrangement. In some embodiments, the mode switching part 10 may not be provided on the operation panel 12, but may be provided directly on the power tool, for example, it may be provided on the handle shell 102 below or above the trigger switch 7, and the operator can use one hand to simultaneously operate the mode switching part 10, the trigger switch 7 and the forward and reverse switching lever 8 in the area. In this way, the operator can operate the power tool with one hand, which is more convenient.
[0108] In some embodiments, the operation panel 12 further includes at least two light emitting units 122 disposed on the main body 121 and configured to indicate a lighting mode and / or an operation mode. The control unit 10 illuminates the light emitting units 122 to indicate a selected lighting mode and / or operation mode.
[0109] Specifically, the control unit 11 determines the selected lighting mode and / or action mode according to the position of the forward / reverse switching lever 8 and the acquired first operation or second operation, and indicates the selected lighting mode and / or action mode by lighting the corresponding light-emitting unit 122 .
[0110] The light-emitting portion 122 may include an indicator light. As shown in FIG6 , this embodiment is described by taking an example in which the electric tool includes four action modes, four lighting modes, and four light-emitting portions 122 are provided on the operation panel 12 .
[0111] The four motion modes include a first speed mode, a second speed mode, a third speed mode, and a wood screw mode, with the speeds corresponding to the first, second, and third speed modes increasing in sequence. The lighting modes include an on mode, an off mode, and a first and second brightness modes in addition to the on and off modes. The brightness corresponding to the first, second, and on modes increases in sequence.
[0112] When the forward / reverse switching lever 8 is in the first position, if the control unit 11 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 10, the light-emitting unit 122 corresponding to the 1st brightness mode is illuminated; if the control unit 11 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 10, the light-emitting unit 122 corresponding to the 2nd brightness mode is illuminated, and so on. For another example, when the forward / reverse switching lever 8 is in the second position, if the control unit 11 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 10, the light-emitting unit 122 corresponding to the wood screw mode is illuminated; if the control unit 11 determines that the currently selected action mode is changed to the first speed mode based on the second operation input by the user to the mode switching unit 10, the light-emitting unit 122 corresponding to the first speed mode is illuminated, and so on.
[0113] All of the light-emitting units 122 are arranged in a row, that is, all of the light-emitting units 122 are arranged in a straight line. This simplifies the design of the operation panel 12, making the structure more compact and orderly, and further reducing the occupied space. In this embodiment, the light-emitting units 122 for indicating the lighting mode and the operation mode are shared, which can make the operation panel 12 more compact and reduce costs.
[0114] In some embodiments, the light-emitting units 122 for indicating the lighting mode and the action mode may not be shared. Specifically, each lighting mode corresponds to a light-emitting unit 122, and each action mode also corresponds to a separate light-emitting unit 122. The number and correspondence of the light-emitting units 122 and modes are not specifically limited herein and will be determined based on actual needs. In this embodiment, the light-emitting units 122 emit light of the same color to indicate the selected lighting mode and / or action mode.
[0115] In some embodiments, the light-emitting portion 122 may also emit different colors of light to indicate the selected action mode and / or lighting mode. For example, when the light-emitting portion 122 includes two light-emitting portions that simultaneously indicate the lighting mode and the action mode, one light-emitting portion 122 is used to indicate the action mode, and the other light-emitting portion 122 is used to indicate the lighting mode. Each light-emitting portion may indicate the selected action mode or lighting mode by emitting different colors of light.
[0116] In some embodiments, the light emitting unit 122 may be a single unit, and different colors of light may be emitted by the light emitting unit 122 to indicate the lighting mode and / or the action mode. Different tones may be used to distinguish between the lighting mode and the action mode. For example, warm tones such as yellow, red, and orange may be used to indicate different lighting modes, while cool tones such as green and blue may be used to indicate different action modes. This is not a limitation.
[0117] In some embodiments, the light-emitting portion 122 provided on the operation panel 12 is used only to indicate that an action mode has been selected, while the lighting component 6 is used to indicate that a lighting mode has been selected. The effect and detailed description of using the lighting component 6 to indicate the selection of a lighting mode are provided in conjunction with the above description and are not further elaborated here. The following example illustrates a situation in which the light-emitting portion 122 provided on the operation panel 12 is used only to indicate that an action mode has been selected, while the lighting component 6 is used to indicate the selection of a lighting mode.
[0118] 6 , this embodiment is described by taking an example in which the electric tool includes four action modes, three lighting modes, and four light-emitting portions 122 are provided on the operation panel 12 .
[0119] The four motion modes include a first speed mode, a second speed mode, a third speed mode, and a wood screw mode, with the speeds corresponding to the first, second, and third speed modes increasing in sequence. The lighting modes include an off mode, a dim mode, and a brightest mode. The off mode turns off the lighting component 6, and the dim mode's brightness is lower than the brightest mode's brightness.
[0120] When the forward / reverse switching lever 8 is in the first position, if the control unit 11 determines that the currently selected lighting mode is the dark mode based on the first operation input by the user to the mode switching unit 10, the lighting component 6 operates at the brightness of the lighting lamp corresponding to the dark mode to indicate that the dark mode is selected; if the control unit 11 determines that the currently selected lighting mode is changed to the brightest mode based on the first operation input by the user to the mode switching unit 10, the lighting component 6 operates at the brightness of the lighting lamp corresponding to the brightest mode to indicate that the brightest mode is selected, and so on. For another example, when the forward / reverse switching lever 8 is in the second position, if the control unit 11 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 10, the light-emitting unit 122 corresponding to the wood screw mode is illuminated; if the control unit 11 determines that the currently selected action mode is changed to the first speed mode based on the second operation input by the user to the mode switching unit 10, the light-emitting unit 122 corresponding to the first speed mode is illuminated, and so on.
[0121] In some embodiments, the operation panel 12 further includes at least two identification portions 123 for identifying a lighting mode and / or an action mode; the identification portions 123 are disposed on the main body 121 and are disposed in a one-to-one correspondence with the light-emitting portions 122 .
[0122] It is understood that in order to facilitate the user to promptly and accurately know the currently switched lighting mode and / or action mode, a marking portion 123 may be provided on the main body 121 of the operation panel 12 corresponding to each light emitting portion 122 .
[0123] As shown in FIG6 , in this embodiment, the power tool's operating modes are identified by the numbers "1," "2," and "3" shown on the identification portion 123, as well as a wood screw mode identifier. This makes the power tool's mode selection clearer, thereby enhancing the user experience. Furthermore, in some embodiments, the numbers "1," "2," and "3," as well as the wood screw mode identifier shown in FIG6 , can also be used to sequentially identify the off mode, brightness level 1 mode, brightness level 2 mode, and the on mode.
[0124] In some embodiments, the operation panel 12 further includes a label 124 disposed on the main body 121 for identifying the function of the mode switching unit 10 . The label 124 at least covers a portion of the mode switching unit 10 .
[0125] As shown in Figure 6 , the character "MODE" and a light indicator can be used as label 124. In this embodiment, the provision of function label 124 facilitates the user's operation of the power tool to switch modes, thereby enhancing the user experience. Furthermore, because label 124 at least partially covers the mode switching portion 10, the compactness of the operating panel is increased.
[0126] 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 trigger is a switch trigger, the mode switching part 10 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.
[0127] In this embodiment, the power tool has multiple action modes and multiple lighting modes, wherein the multiple action modes include 1st speed, 2nd speed, 3rd speed and wood screw mode, and the multiple lighting modes include off mode, dark mode and brightest mode.
[0128] Referring to Figure 2 in conjunction with Figures 3 and 6 , this embodiment of the power tool features a forward / reverse switching lever 8 below the main body housing 101. The battery pack receiving housing 103 houses an operating panel 12, which includes a mode switch button and four indicator lights. The four indicator lights sequentially indicate speed 1, speed 2, speed 3, and the wood screw mode. Furthermore, a button label 124 is located above the mode switch button and features the words "MODE" and "Light" along the width of the operating panel.
[0129] First, pull the switch trigger to power on the MCU (also called pre-lighting; the battery pack supplies power to the MCU. When the switch trigger travels within the 1mm to 1.4mm range, the MCU powers on). At this point, the lighting lamp 603 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 after power is turned on, indicating that the current operating mode is wood screw mode. At this point, pulling the switch trigger will trigger the power tool to operate in wood screw mode.
[0130] If it is necessary to switch the brightness of the lighting lamp 603, the forward and reverse switching lever 8 is operated to the neutral position, and the mode switching button is operated to switch the lighting mode. If it is necessary to switch the action mode, the forward and reverse switching lever 8 is operated to the forward or reverse gear position, and the mode switching button is operated to switch the action mode.
[0131] When the lighting mode and action mode are selected, operate the switch trigger and make the switch trigger stroke reach the pre-lighting stroke, the lighting lamp 603 will light up according to the selected lighting mode, and continue to pull the switch trigger to make the MCU control the motor 2 to drive in the selected action mode.
[0132] Among them, the action mode may include: 3-speed mode + wood screw mode. Of course, in some embodiments, it can also be 3-speed mode + forward and reverse self-stop mode, etc. The type of action mode is not specifically limited here. In some embodiments, the lighting mode may also include four modes: brightest, bright, dark, and off, and may also 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 the mode switching button for a predetermined time, etc. 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 is received.
[0133] In this embodiment, the lighting mode may not be indicated by an indicator light on the operation panel, and the operator may perceive the selected lighting mode based on the brightness of the lighting lamp 602. In some embodiments, the indicator light for the action mode may be reused as the indicator light for the lighting mode.
[0134] Furthermore, in this embodiment, if no operation is performed on the power tool (including completely releasing the switch trigger, not switching modes, etc.), and the motor 2 stops operating for more than 15 seconds, the light 602 will be turned off. If the switch trigger travel remains within the pre-lighting range, the light 602 will be turned off after 10 minutes of being on.
[0135] The control process of the power tool in this embodiment is described below based on different scenarios.
[0136] Scenario 1: When the motor 2 is not in operation, the mode switch button is operated to turn the light on or off and switch the brightness of the light. FIG7 is a process diagram of the control method of the power tool provided by an embodiment of the present invention. As shown in FIG7, the control method of the power tool of this embodiment includes the following steps:
[0137] Step S10, detect whether the signal of the forward / reverse switching lever 8 is a neutral position signal, if so, execute step S20, otherwise execute step S40. In this embodiment, since the trigger switch 7 cannot be pressed to the stroke that drives the motor 2 when the forward / reverse switching lever 8 is in the neutral position, the motor 2 cannot be driven, and when the power tool is powered on and the motor 2 is not driven, the power tool is in a standby state. In this embodiment, when the forward / reverse switching lever 8 is in the forward position or the reverse position, the operator presses the trigger switch 7 to power on the power tool. In some embodiments, the trigger switch 7 can also be pressed a small stroke to power on when the forward / reverse switching lever 8 is in the neutral position, and the motor 2 cannot be driven when the trigger switch 7 is pressed within this small stroke.
[0138] It is understandable that after power-on, the MCU can detect in real time whether the signal of the forward / reverse switching lever 8 is a neutral position signal, that is, whether the gear position of the forward / reverse switching lever 8 is in the neutral position. If so, step S20 is executed, otherwise step S40 is executed.
[0139] 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 .
[0140] The operation signal may be a single-click operation signal, a double-click operation signal, etc., which is not specifically limited here.
[0141] Step S30: Switch the lighting mode and operate the lamp in the selected lighting mode. In this embodiment, operating the lamp in the selected lighting mode may include operating the mode switch button to switch the lighting mode simultaneously with the selected lighting mode. Alternatively, after operating the mode switch button to switch the lighting mode, the forward / reverse switching lever 8 is moved to a non-neutral position and then the trigger switch 7 is pulled to control the lamp in the selected lighting mode. In an alternative embodiment, the trigger switch 7 may be pulled to control the lamp in the selected lighting mode when the forward / reverse switching lever 8 is moved to the neutral position. However, in this case, the trigger switch 7 can only be pulled a small distance and cannot be pulled to activate the motor 2. Furthermore, when the lamp is on, the lamp remains on while the switch trigger is operated to activate the motor 2. If no operation is performed and the motor 2 stops for more than 15 seconds, the lamp is turned off. Furthermore, if the switch trigger remains in the pre-lighting mode for more than 10 minutes after the lamp 602 is on, the lamp is turned off.
[0142] It is understandable that, 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.
[0143] Step S40: Check whether the device is in standby mode. If yes, go to step S50; otherwise, go back to step S10.
[0144] It is understood that when the MCU detects that the gear position of the forward / reverse switching lever 8 is not in the neutral position, it can detect whether the signal of the forward / reverse switching lever 8 is a non-neutral position signal. In addition, in this embodiment, detecting whether the motor 2 is in the standby state, that is, detecting whether the motor 2 is operating, can generally be detected by detecting whether the motor 2 is reversing, and whether the current or voltage flowing through the motor 2 exceeds a threshold.
[0145] 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 .
[0146] Step S60: switch the action mode.
[0147] It is understandable that, 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.
[0148] Scenario 2: When the motor 2 is in the working state, that is, after the pressing stroke of the switch trigger exceeds the predetermined stroke, the mode switching button is operated to turn the light on or off and switch the brightness of the light.
[0149] FIG8 is a process diagram of a method for controlling an electric tool according to an embodiment of the present invention. FIG8 is combined with FIG8 to illustrate another method for controlling an electric tool according to this embodiment, which includes the following steps:
[0150] Step S100: Detect whether the trigger switch 7 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 2 starts to operate. In this step, detecting whether the trigger switch 7 is pressed to the predetermined stroke indicates that the MCU has driven the motor 2 to start operating, i.e., it is in a non-standby state.
[0151] 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 .
[0152] Step S300: switch the lighting mode and drive the lighting lamp 602 to work according to the selected lighting mode.
[0153] It is understandable that 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 7.
[0154] Step S400: Check whether it is in standby state. If so, execute step S500; otherwise, return to execute step S100.
[0155] 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 .
[0156] Step S600: The lighting is turned off and the operation mode is switched.
[0157] In summary, in the power tool provided by this embodiment, when the motor is not operating and the forward / reverse switching lever is in the neutral position, the button can be operated to switch the lighting mode, and then the trigger can be operated to drive the light in the selected lighting mode. When the motor is operating 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 reduces the size and cost of the power tool, improves accessibility to the sole of the power tool, and enhances the convenience of mode switching.
