Power tool

Abstract

In the electric tool, when the operation part is operated in the first mode, the controller selects one of the at least two main working modes as the current main working mode. At this time, the main light-emitting part is lighted to indicate that the current main working mode is selected. When the operation part is operated in the second mode, the controller selects one of the at least two subdivided working modes as the current subdivided working mode in the current main working mode. At this time, the main light-emitting part remains lighted, and the subdivided light-emitting part is lighted to indicate that the current subdivided working mode is selected. In this way, the multi-mode regulation of the electric tool is more intelligent, and the mode regulation is facilitated. In addition, the control and indication of different types of main working modes and subdivided working modes are integrated on one operation part, which is beneficial to reduce the overall size of the operation panel and reduce the space occupation on the machine body.

Description

Technical Field

[0001] This invention relates to the field of electric equipment technology, and in particular to power tools. Background Technology

[0002] With the rapid development of electric technology, the application of power tools is becoming more and more widespread, and the types of power tools being developed are also increasing. For example, tools such as electric drills and screwdrivers use electric drive to replace manual labor, thereby reducing labor intensity and improving work efficiency.

[0003] Traditional power tools have relatively simple control panel settings, allowing only control within a single mode. For example, operating a trigger switch allows selection of LOW, MID, HIGH, and TEKS modes, sequentially changing the motor speed. Based on this control panel design, existing multi-mode power devices typically increase the number of trigger switches, using different switches to control different modes. However, this design inevitably leads to a larger overall control panel size, increasing space usage. Furthermore, operation requires separate steps, resulting in low levels of automation and inconvenience in controlling the power device's modes.

[0004] In addition, traditional power tools are equipped with lights to illuminate the surrounding environment, increasing brightness in low-light conditions to ensure proper operation. However, current power tools control the light's on / off state via a trigger. Opening the trigger activates the light, and closing it deactivates it. This means that when the light is not needed, such as during daytime outdoor work when ambient light is sufficient, turning it on increases energy consumption and reduces battery life. Similarly, when the power tool is working on highly reflective metal surfaces, the reflected light can interfere with the operator's work. Summary of the Invention

[0005] Therefore, it is necessary to provide a power tool that, under multi-mode control, can balance the space occupied by the control panel and the degree of intelligent control, improve the performance of the power tool, and make the control of the lighting not only dependent on the operation of triggering, but also flexible and convenient to operate.

[0006] This invention provides a power tool having at least two main working modes, wherein each main working mode includes at least two corresponding sub-working modes, and the power tool further includes:

[0007] The motor is configured to generate driving force to operate the power tool.

[0008] A trigger is configured to be pressed to drive the motor;

[0017] At least one of the light-emitting portions can emit light of at least two colors, and the light emitted by the light-emitting portion corresponds one-to-one with the identification portion.

[0018] In one embodiment, the projections of the light-emitting portion and at least one corresponding sub-identifier portion on the operation panel at least partially overlap; or, the light-emitting portion and the corresponding sub-identifier portion are spaced apart.

[0019] In one embodiment, the main body has a first region, a second region, and a third region. The operating part is located in the first region, the main light-emitting part is located in the second region, and the sub-light-emitting parts are all located in the third region. The first region, the second region, and the third region are arranged in a straight line.

[0020] In one embodiment, there are at least two main light-emitting parts and / or at least two sub-light-emitting parts. When there are at least two main light-emitting parts, all the main light-emitting parts are arranged along a first direction. When there are at least two sub-light-emitting parts, all the sub-light-emitting parts are arranged along a second direction, and the first direction intersects with the second direction.

[0021] In one embodiment, the first direction shown is perpendicular to the second direction.

[0022] In one embodiment, the line connecting all the light-emitting portions is located between two adjacent main light-emitting portions.

[0023] In one embodiment, the main body is provided with a contour portion surrounding the operating portion, the contour portion having an upper edge and a lower edge, and the main light-emitting portion and the secondary light-emitting portion being at least partially located between the upper edge and the lower edge.

[0025] In one embodiment, the first mode is configured to connect the operation unit a first predetermined number of times within a set time period, and the second mode is configured to connect the operation unit a second predetermined number of times within the set time period, wherein the first predetermined number of times and the second predetermined number of times are different.

[0026] In one embodiment, the power tool further includes:

[0027] A lighting fixture, the lighting fixture being used to illuminate the exterior of the power tool; and,

[0028] The controller is configured to turn the light on or off according to the operation of the operating unit when the trigger is pressed to a predetermined stroke.

Furthermore, integrating the control and indication of different types of main working modes and sub-modes into a single operating section helps to reduce the overall size of the control panel and its space occupation on the machine body.

[0082] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0083] like Figure 1 and Figure 2 As shown, the power tool 1 of this embodiment is a rechargeable impact drive device. The power tool 1 includes a main body 200, a handle 300, a foot 400, and a battery pack 500. The handle 300 extends downward from the main body 200, and the foot 400 is located below the handle 300. The battery pack 500 is detachably mounted on the lower end of the foot 400, wherein the battery pack 500 contains a built-in battery.

[0084] The main body 200 includes a main body shell 210 assembled from a first half-shell 211 and a second half-shell 212. A motor 220 is housed at the rear of the main body shell 210, and a sleeve 600 protrudes from the front end of the main body shell 210. The rotational drive of the motor 220 is reduced in speed by a gearbox and then transmitted to the sleeve 600. Based on this rotational drive force, an impact mechanism applies intermittent impacts to the sleeve 600 in its rotational direction. The impact mechanism includes a spindle, a hammer, and an anvil. The spindle rotates via the gearbox, the hammer rotates with the spindle and is axially movable, and the anvil is located in front of the hammer. A tool head (e.g., a drill bit, screwdriver bit, etc.) is mounted at the front end of the anvil via the sleeve 600.

[0085] Specifically, the spindle rotates along with the motor 220. The spindle rotation drives the hammer and anvil to rotate, which in turn causes the sleeve 600 to rotate, thereby rotating the tool head. Furthermore, the hammer can apply intermittent impacts to the anvil, thus providing a greater force to the tool head for tightening or loosening operations. For a detailed description of the main body structure, please refer to patent application number CN201210537261.8; further details will not be elaborated here.

[0086] Continue to participate Figure 1 and combined Figure 2 As shown, a trigger 310 is provided on the upper front side of the handle 300, which can be operated (pressed) when the user of the power tool 1 is holding the handle 300.

[0087] The trigger 310 is configured to be pressed to control the drive of the motor 220. A controller 700 is housed within the foot portion 400. This controller 700 receives power from the battery pack 500 to supply power to the motor 220, causing the motor 220 to operate and rotate according to the amount of operation of the trigger 310. In an optional embodiment, the controller 700 may also be housed within the handle portion 300.

[0088] In addition, an operation panel 100 electrically connected to the controller 700 is provided on the foot portion 400. A light 800 is provided in front of the operation panel 100 to illuminate the exterior of the power tool 1. The operation panel 100 includes an operation section 120 and multiple light-emitting sections. The operation section 120 controls the switching of the power tool 1's operating modes and selects one mode at a time. The light-emitting sections indicate the selected operating mode; specifically, illuminating at least one of the light-emitting sections indicates that the operating mode selected by operating the operation section 120 has been chosen. In this embodiment, the operation section 120 and the multiple light-emitting sections are located on the upper surface of the operation panel 100 exposed above the foot portion 400, i.e., the operation section 120 and the light-emitting sections are located on the same surface of the power tool 1 exposed to the outside. This allows for a compact structure, saves space, and facilitates operation and visibility. In addition, in optional embodiments, the operation part 120 and the light-emitting part may not be provided on the same operation panel 100. For example, they may be provided separately on the power tool 1, so that the operation part 120 and the light-emitting part are provided on the same surface of the power tool 1 that is exposed to the outside.

[0089] In this embodiment, the working modes include a main working mode and sub-modes. The main working mode can be, but is not limited to, a speed mode, a function mode, or a scenario mode. In speed mode, the power tool can output different speeds. In function or scenario mode, the power tool can perform operations corresponding to specific application scenarios to meet the needs of different working conditions. Meanwhile, sub-modes should be understood as the specific range of parameter adjustment for the power tool under different main working modes. For example, in speed mode, sub-modes can be 1st, 2nd, 3rd, 4th speed, etc.; or low speed, medium speed, high speed, etc. In function or scenario mode, sub-modes can be wood mode, automatic stop mode, thin iron mode, and thick iron mode, etc.

[0090] In optional embodiments, the operating modes may not include the aforementioned main operating mode and sub-operating modes, but only include: a first speed mode, a second speed mode, a third speed mode, and an automatic stop mode. The speeds corresponding to the first speed mode, second speed mode, and third speed mode increase sequentially. Furthermore, the automatic stop mode is a mode in which the motor 220 stops after detecting an impact and then detecting that the current is less than a preset threshold. Of course, the operating modes are not limited to the above-mentioned modes; other operating modes may also be included, without specific limitations here.

[0091] Continue to participate Figure 2 and combined Figure 1 To illustrate the control system for controlling the motor 220 and the lighting lamp 800 in this embodiment, the control system includes: a battery pack 500, a controller 700 electrically connected to the battery pack 500, and an operation panel 100. The controller 700 includes a motor control unit 710, a control circuit 720, a trigger detection unit 730, and a power supply circuit 740.

[0092] In this embodiment, the motor 220 is a brushless motor and is electrically connected to the battery pack 500 via a motor control unit 710. The motor control unit 710 consists of a full-bridge circuit composed of six switching elements, such as six MOSFETs. The control circuit 720 controls the rotation of the motor 220 by outputting drive signals to each switching element of the full-bridge circuit to turn these switching elements on or off.

[0093] The power supply circuit section 740 steps down the DC voltage from the battery pack 500 to generate a suitable control voltage, which is then applied to the control circuit 720 to supply power to the various circuits within the controller 700. The various circuits within the controller 700 operate powered by the control voltage from the power supply circuit section 740. Furthermore, in this embodiment, the trigger detection section 730 is used to detect the operating state of the trigger 310.

[0094] Further, continue to participate Figure 2 As shown, in this embodiment, the control circuit 720 includes a CPU 721, a ROM 722, a RAM 723, and a flash memory 724. The flash memory 724 and RAM 723 are used to store temporary programs; these programs are not saved when the power tool 1 is powered off. The ROM 722 stores fixed programs, which are saved when the power tool 1 is powered off. In this embodiment, programs such as the working mode are stored in the ROM 722, while programs such as temporary parameter modifications are stored in the flash memory 724 or RAM 723. The CPU 721 is used to retrieve programs from the ROM 722, RAM 723, and flash memory 724 to drive the motor 220, or to control the lighting lamp 800 to turn on or off, based on operations from the operation panel 100 and the trigger 310.

[0095] Continue to participate Figure 2 and combined Figure 3 As shown, in this embodiment, the working mode includes a main working mode and multiple sub-working modes as an example for explanation. In this embodiment, the operation panel 100 includes a main body 110 and an operation part 120, at least one main light-emitting part 130, and at least one sub-light-emitting part 150 disposed on the main body 110. In this embodiment, there is only one operation part 120. In addition, the main body 110 is divided into a first region 111, a second region 112, and a third region 113. The operation part 120 is located in the first region 111, the main light-emitting part 130 is located in the second region 112, and the sub-light-emitting parts 150 are all located in the third region 113. The first region 111, the second region 112, and the third region 113 are arranged in a straight line. That is, the main body 110 is planned into three regions, and the operation part 120 is included in the first region 111; the indication part of the main working mode is included in the second region 112; and the indication part of the sub-working modes is included in the third region 113. This unified division of different functions ensures that the operation panel's control and indication are more intuitive and effective.

[0096] It should be noted that when the first region 111, the second region 112, and the third region 113 are arranged in a straight line on the main body 110, they are not limited to a specific order. For example, the first region 111 can be located between the second region 112 and the third region 113; or, as... Figure 4 As shown, the third region 113 is located between the first region 111 and the second region 112.

[0097] In other embodiments, please refer to Figure 5The first region 111, the second region 112, and the third region 113 are arranged in a triangular pattern. Of course, in other embodiments, the main body 110 may not be divided into regions, that is, the sub-identifiers 160 may be intertwined with the main identifiers 140, for example, the sub-identifiers 160 may be arranged in a circular pattern around the corresponding main identifiers 140.

[0098] Further participation Figure 3 As shown, in this embodiment, the controller 700 is configured to: operate in a first manner according to the operation unit 120, select a main operating mode from at least two main operating modes, and indicate that the selected main operating mode has been selected by illuminating at least one of the main light-emitting units 130. Operate in a second manner according to the operation unit 120, select a sub-operating mode from at least two sub-operating modes, in which case the main light-emitting unit 130 remains illuminated, and indicate that the selected sub-operating mode has been selected by illuminating at least one sub-light-emitting unit 150. Furthermore, in this embodiment, when switching and selecting the above operating modes, the power tool 1 is in standby mode, that is, the motor 220 is not driven at this time. This avoids sudden changes in the drive of the motor 220 due to switching and selecting the operating mode while the motor 220 is driven, thus preventing accidents and improving the safety of operating the power tool 1. Furthermore, when the subdivision mode is selected, the trigger 310 is triggered. After the trigger detection unit 730 detects the trigger signal of the trigger 310, it transmits the trigger signal to the CPU 721. The CPU 721 controls the motor 220 to drive the motor 220 according to the control program corresponding to the selected subdivision mode. That is, at this time, the power tool 1 starts to work and the power tool 1 enters the driving state.

[0099] The aforementioned power tool 1 has an operation section 120, a main light-emitting section 130, and a sub-light-emitting section 150 on its operation panel 100. When the operation section 120 is operated in a first manner, the controller selects one of at least two main working modes as the current main working mode. At this time, the main light-emitting section 130 is illuminated to indicate that the current main working mode has been selected. When the operation section 120 is operated in a second manner, the controller selects one of at least two sub-working modes as the current sub-working mode within the current main working mode. At this time, the main light-emitting section 130 remains illuminated, and the sub-light-emitting section 150 is illuminated to indicate that the current sub-working mode has been selected. Therefore, the operation panel 100 of this application, using only the operation section 120, can realize the switching of the power tool between different types of main working modes and can switch between corresponding types of sub-working modes within the selected main working mode; simultaneously, the main light-emitting section 130 and the sub-light-emitting section 150 effectively indicate the current main working mode and sub-working mode, making the multi-mode control of the power tool more intelligent and convenient for mode control. Furthermore, integrating the control of different main working modes and sub-modes onto a single operating unit 120 helps reduce the overall size of the operating panel 100 and its space occupation on the machine body. This design allows the operating panel 100 to balance space occupation and intelligent control under multi-mode control, thereby improving the performance of the power tool.

[0100] It should also be noted that in this embodiment, the operation unit 120 is a single operation button. The first mode and the second mode of the operation unit 120 are different operation methods, allowing the operator to clearly distinguish between the control of the main working mode and the sub-mode. These "different operation methods" can be the same action, but maintained for different durations or with different frequencies, such as: both being press-to-activate, but with long presses, short presses, double presses, single presses, etc.; or they can be different actions, for example: the operation unit 120 includes a button and a rotating adjustment ring fitted around the button, where switching the main working mode is triggered by rotating the adjustment ring, and switching the sub-mode is triggered by activating the button, etc.

[0101] When the power tool 1 selects a mode in either the first or second mode, a priority can be set between the first and second modes. That is, if the power tool is operated in the second mode before the first mode is used, the power tool will not respond, and the light-emitting part 150 will remain off. Only when the first mode is used first, and then the second mode is used, will the light-emitting part 150 be illuminated accordingly.

[0102] If the second method is used, and then the first method is used again, the lighting status of the sub-light-emitting unit 150 will have at least two possibilities: 1. If the first method is used again to operate the operation unit 120, the sub-light-emitting unit 150 will be reset, meaning it will be completely off; 2. If the first method is used again to operate the operation unit 120, the lighting status of the sub-light-emitting unit 150 will remain consistent with the lighting status before the first method was triggered, i.e., it has a memory function. It should be noted that the second method operation does not affect the lighting status of the main light-emitting unit 130; that is, the main light-emitting unit 130 remains lit.

[0103] In this embodiment, the first configuration is to keep the operation unit 120 on for a first preset time, and the second configuration is to keep the operation unit 120 on for a second preset time, the second preset time being different from the first preset time. In this embodiment, the operation unit 120 is an operation button, and the operation unit 120 is activated by pressing it. Furthermore, the difference between the second and first preset times can be understood as either the second preset time being shorter than the first preset time, or the second preset time being longer than the first preset time. Thus, by varying the activation time of the operation unit 120, the controller receives corresponding control signals, causing the power tool to switch to the corresponding main working mode and sub-mode.

[0104] Furthermore, in this embodiment, the second preset time is less than the first preset time; that is, the first method can be understood as a long press, and the second method can be understood as a short press. The first preset time is greater than 500ms, and the second preset time is less than 500ms.

[0105] In one embodiment, a first configuration involves activating the operation unit 120 a first predetermined number of times within a set time period, and a second configuration involves activating the operation unit 120 a second predetermined number of times within a set time period, wherein the first predetermined number of times and the second predetermined number of times are different. The difference between the second predetermined number of times and the first predetermined number of times can be understood as either the second predetermined number of times being less than the first predetermined number of times, or the second predetermined number of times being more than the first predetermined number of times. Thus, by varying the number of activations of the operation unit 120, the controller receives corresponding control signals, causing the power tool to switch to the corresponding main working mode and sub-working mode.

[0106] Furthermore, the first predetermined number of times is greater than the second predetermined number of times. Specifically, in some embodiments, the first method is double-clicking, and the second method is single-clicking. The first and second methods of operation of the operation unit 120 are not specifically limited here, but are subject to actual conditions.

[0107] Furthermore, continue to participate Figure 3As shown, the operation panel 100 also includes at least two main indicator sections 140 for indicating the main working mode and at least two sub-indicator sections 160 for indicating sub-modes. Each main indicator section 140 corresponds to a main working mode, and each sub-indicator section 160 corresponds to a sub-mode. Therefore, when the operation unit 120 is operated in the first mode, the main indicator section 130 switches between the main indicator sections 140 to indicate the type of the currently selected main working mode. When the operation unit 120 is operated in the second mode, the main indicator section 130 specifies that one of the main indicator sections 140 remains unchanged, i.e., the main working mode remains unchanged. Simultaneously, with the operation in the second mode, the sub-indicator sections 150 switch between the sub-indicator sections 160 to indicate that the power tool is in a sub-mode within the selected main working mode. This makes the mode selection of the power tool clearer and improves the user experience.

[0108] In one embodiment, please continue to refer to Figure 3 As shown, there are at least two main light-emitting parts 130 and / or at least two sub-light-emitting parts 150. When there are at least two main light-emitting parts 130, all main light-emitting parts 130 are arranged along a first direction X. When there are at least two sub-light-emitting parts 150, all sub-light-emitting parts 150 are arranged along a second direction Y, and the first direction X and the second direction Y intersect. Therefore, the arrangement of the main light-emitting parts 130 and the sub-light-emitting parts 150 is intersecting, which improves compactness and allows operators to quickly and accurately distinguish between the main light-emitting parts 130 and the sub-light-emitting parts 150, thus improving the user experience of the product.

[0109] Optionally, the intersection angle between the first direction X and the second direction Y can be set to an acute angle, a right angle, or an obtuse angle. Specifically, the first direction X is perpendicular to the second direction Y, which not only makes it easy to distinguish between the main light-emitting part 130 and the sub-light-emitting part 150, but also ensures that the surface of the operation panel 100 is neatly arranged, which is beneficial to improving the appearance.

[0110] In one embodiment, the line connecting all the light-emitting sections 150 is located between two adjacent main light-emitting sections 130. Please continue reading. Figure 3 As shown, all the light-emitting parts 150 are connected to form an arrangement line 151. At this time, the extension line of the arrangement line 151 is located between two adjacent main light-emitting parts 130. This helps to limit the distribution range of all the light-emitting parts 150 to between two adjacent main light-emitting parts 130, making the structure on the operation panel 100 more compact and facilitating the miniaturization of the operation panel 100.

[0111] In one embodiment, the main light-emitting part 130 and the secondary light-emitting parts 150 are arranged in a row. That is, all the light-emitting parts are arranged in a straight line, which helps to simplify the design of the operation panel 100 and makes the structure more compact and orderly.

[0112] It should be noted that when the main light-emitting part 130 and the sub-light-emitting parts 150 are arranged in a row, the main light-emitting part 130 can be placed at the outermost end of the row. For example, the main light-emitting part 130 can be placed at the beginning or end of all the sub-light-emitting parts 150. When arranging them, try not to mix the main light-emitting part 130 with the sub-light-emitting parts 150, as this can easily cause operational confusion.

[0113] Further, continue to participate Figure 3 As shown, in one embodiment, the main body 110 is provided with a contour portion 170. The contour portion 170 is disposed around the operation portion 120, and the height of the contour portion 170 protruding from the main body 110 is approximately equal to that of the operation portion 120. The contour portion 170 makes the operation panel 100 aesthetically pleasing and can protect the operation portion 120. The contour portion 170 has an upper edge 171 and a lower edge 172. The main light-emitting portion 130 and the sub-light-emitting portion 150 are at least partially located between the upper edge 171 and the lower edge 172, that is, defining the distribution range of the main light-emitting portion 130 and the sub-light-emitting portion 150, avoiding a dispersed arrangement that would reduce the space utilization on the operation panel 100.

[0114] It should be noted that the upper edge line 171 and the lower edge line 172 should be understood as: in a preset direction (such as the first direction X, etc.), the two tangent lines passing through the two edge points on the outermost edge of the contour part 170 are the upper edge line 171 and the lower edge line 172.

[0115] It should be noted that the number of main light-emitting units 130 can be one or more. Please refer to [reference needed]. Figures 3 to 7 As shown, there are multiple main light-emitting units 130, each corresponding to a main indicator unit 140. When the operation unit 120 is operated in the first mode, one of the main light-emitting units 130 lights up, indicating that the main operating mode corresponding to the main indicator unit 140 has been selected. This one-to-one correspondence between the main light-emitting units 130 and the main indicator units 140 makes multi-mode adjustment of power tools more convenient and easier for operators to use.

[0116] In addition, in this embodiment, please refer to Figures 3-5 as well as Figure 7 As shown, the projections of the main indicator 140 and the corresponding main light-emitting part 130 on the operation panel 100 overlap at least partially, that is, the main indicator 140 covers the corresponding main light-emitting part 130. This not only makes it easier for the operator to intuitively judge the mode type of the power tool, but also makes the structure of the operation panel 100 more compact, which is conducive to the miniaturization design of the operation panel 100.

[0117] Furthermore, in an optional embodiment, the main identifier 140 is located on any circumferential side of the corresponding main light-emitting portion 130. Here, "any circumferential side" should be understood as a side surrounding the main light-emitting portion 130, such as the upper, lower, left, or right side of the main light-emitting portion 130. Additionally, when there are multiple main light-emitting portions 130, they can be arranged horizontally or vertically; they can also be arranged in a matrix to improve the compactness of the operation panel 100 structure. For example, as... Figure 6 As shown, the two main light-emitting parts 130 are located between the two main marking parts 140 and are arranged vertically.

[0118] Please refer to Figures 8 to 10 As shown, when there is only one main light-emitting part 130, all main indicator parts 140 are switched by the same main light-emitting part 130. In this case, in order to facilitate the differentiation of indicators, the main light-emitting part 130 can be designed as a multi-color indicator light, or it can be designed as an indicator light with constant light and flashing functions; or it can directly display the corresponding indicator pattern (for example, the main light-emitting part 130 integrates multiple LED beads, which can display the corresponding pattern through different arrangements and combinations).

[0119] For details, please continue to refer to [the website / information]. Figures 8 to 10 As shown, at least one main light-emitting unit 130 can emit light of at least two colors. The light emitted by the main light-emitting unit 130 corresponds one-to-one with the main indicator unit 140. That is, the main light-emitting unit 130 is a multi-color lamp. The different colors of light emitted by the main light-emitting unit 130 are used to indicate the main indicator unit 140, thereby instructing the power tool to switch to the corresponding main working mode. In this way, it is beneficial to reduce the number of main light-emitting units 130 and reduce power consumption.

[0120] To facilitate operators in quickly identifying the main working mode of the power tool, the main marking section 140 can be painted with a color consistent with the light emitted by the main light-emitting section 130. For example, the main light-emitting section 130 can emit green and red light, and one of the two main marking sections 140 can be painted green and the other red. Furthermore, the main marking section 140 can be formed on the main body 110 through spraying, engraving, laser engraving, or other methods; and to facilitate identification of the operating section 120, the word "SET" or similar can be marked on the operating section 120.

[0121] In one embodiment, the reference Figures 3 to 6As shown, each light-emitting unit 150 can indicate at least two sub-modes belonging to different main working modes. Each light-emitting unit 150 emits light of the same color for indication, and each sub-mode corresponds to a sub-identifier unit 160. For example, in this embodiment, the speed modes include speed level 1, speed level 2, speed level 3, and speed level 4, and the scene modes include wood mode, thin iron mode, thick iron mode, and automatic stop mode. The four sub-identifier units 160 in the first row are labeled with the numbers 1, 2, 3, and 4 respectively to identify the four speed levels. The four sub-identifier units 160 in the second row are labeled with wood, thin iron, thick iron, and automatic stop respectively to identify the four scene modes. The four light-emitting units 150 are arranged in a row between the two rows of sub-identifier units 160, and sequentially indicate wood mode and speed level 1 mode, thin iron mode and speed level 2 mode, thick iron mode and speed level 3 mode, and automatic stop mode and speed level 4 mode respectively. In this embodiment, taking the operation unit 120 selecting speed level 1 mode and wood mode as an example, when speed level 1 mode is selected, the operation unit 120 is operated in a first manner to select the speed mode in the main working mode. At this time, the main light-emitting part 130 indicating the speed mode is lit. Then, the operation unit 120 is operated in a second manner to select speed level 1. At this time, the main light-emitting part 130 indicating the speed mode remains lit, and the leftmost sub-light-emitting part 150 indicating speed level 1 is lit. When wood mode is selected, the operation unit 120 is operated in a first manner to select the scene mode in the main working mode. At this time, the main light-emitting part 130 indicating the scene mode is lit. Then, the operation unit 120 is operated in a second manner to select wood mode. At this time, the main light-emitting part 130 indicating the scene mode remains lit, and the leftmost sub-light-emitting part 150 indicating wood mode is lit.

[0122] In an optional embodiment, at least one light-emitting part 150 can emit light of at least two colors. The light emitted by the light-emitting part 150 corresponds one-to-one with the sub-marking part 160. That is, the light-emitting part 150 is a multi-color lamp. The different light colors emitted by the light-emitting part 150 correspond to the sub-marking part 160 to indicate the power tool to switch to the corresponding sub-division working mode. This helps to reduce the number of light-emitting parts 150 and reduce power consumption.

[0123] The light-emitting part 150 can also be provided as a single unit, for example... Figure 7 and Figure 10As shown, the sub-light-emitting section 150 is a multi-color lamp, and the sub-mode is indicated entirely by the color of the light emitted by the sub-light-emitting section 150. This saves space. Similarly, to facilitate the operator's quick identification of the main working mode of the power tool, the sub-marker section 160 can be painted with a color consistent with the light emitted by the sub-marker section 160. For example, the sub-light-emitting section 150 can emit green and red light, and one of the two sub-marker sections 160 can be painted green and the other red, etc.

[0124] In addition, participants Figure 9 As shown, in an optional embodiment, the number of light-emitting parts 150 can also be the same as the number of marking parts 160, that is, the light-emitting parts 150 and the marking parts 160 correspond one-to-one, so that one-to-one indication can be performed, the visual effect is better, and the indication is more accurate.

[0125] It should be noted that the number of sub-light-emitting parts 150 and the number of main light-emitting parts 130 can be freely combined to form different operation panel 100 structures. When there is one main light-emitting part 130, there can be one or more sub-light-emitting parts 150. When there are multiple main light-emitting parts 130, there can be one or more sub-light-emitting parts 150. Specifically, when there are multiple main light-emitting parts 130, the operation unit 120 can be operated repeatedly in a first manner, lighting up back and forth among the main light-emitting parts 130 in a certain order; similarly, when there are multiple sub-light-emitting parts 150, the operation unit 120 can be operated repeatedly in a second manner, lighting up back and forth among the sub-light-emitting parts 150 in a certain order.

[0126] In one embodiment, such as Figure 9 As shown, the projections of the sub-marker 160 and the corresponding sub-light-emitting part 150 on the operation panel 100 at least partially overlap, so that the structure of the operation panel 100 remains compact. Furthermore, by arranging the sub-light-emitting part 150 and the sub-marker 160 appropriately, the operator can more intuitively determine the indicated mode type.

[0127] Alternatively, in an alternative embodiment, please refer to Figure 8 As shown, the light-emitting portion 150 and its corresponding marking portion 160 are spaced apart, meaning there is a gap between the light-emitting portion 150 and its corresponding marking portion 160, and they do not overlap. Specifically, the marking portion 160 can be located above, below, to the left, or to the right of the light-emitting portion 150, etc.

[0128] The following describes the control of turning the lighting lamp 800 on and off in this embodiment.

[0129] Continue to participate Figure 1 and Figure 2As shown, in this embodiment, when the trigger 310 is pressed to a predetermined stroke, the lighting lamp 800 can be turned on or off according to the operation of the operation unit 120. The predetermined stroke includes the stroke from when the trigger 310 is pressed to put the controller 700 into working state, i.e., powering on the power tool 1, until the trigger 310 is pressed all the way down and can no longer be moved.

[0130] It should be noted that in this embodiment, the power tool includes a standby state and a driving state. The trigger has a first predetermined stroke and a second predetermined stroke, wherein the second predetermined stroke is greater than the first predetermined stroke.

[0131] In this embodiment, the controller 700 is configured to power on the power tool 1 when the trigger 310 is pressed to at least a first predetermined stroke, at which point the controller 700 enters the working state. Powering on the power tool 1 means that the battery pack 500 supplies power to the power tool 1. Furthermore, in this embodiment, if the power tool 1 is not operated for a certain period of time after being powered on, the power tool 1 will be powered off. Operation of the power tool 1 includes pressing the trigger 310, operating the operating unit 120, etc. Powering off the power tool 1 means that the power supply from the battery pack 500 to the power tool 1 is cut off, at which point the controller 700 exits the working state. If the power tool 1 needs to be used again after being powered off, the trigger 310 must be pressed again to at least the first predetermined stroke to power on the power tool 1 again and to bring the controller 700 back into the working state.

[0132] After the controller 700 enters the working state, if the trigger is pressed to the second predetermined stroke, the power tool will enter the driving state. If the second predetermined stroke is not reached, the power tool will remain in standby mode. If the trigger 310 is released after the controller 700 enters the working state or the power tool enters the driving state, and the power tool does not lose power within a predetermined time after the trigger 310 is released, the controller 700 will remain in the working state, and the power tool will remain in standby mode. In other words, when the controller 700 enters the working state but the power tool 1 is not in the driving state, the power tool 1 is in standby mode. When the trigger 310 is released for a predetermined time, the power tool 1 loses power, and the controller 700 exits the working state.

[0133] When the trigger 310 is pressed to the second predetermined stroke, the controller 700 controls the power tool 1 to enter the drive state. This drive state refers to the state in which the motor 220 is driven. The drive state may include the state in which the working head is installed and the power tool is used to tighten or loosen bolts / screws, or it may include the state in which the working head is not installed and the tool is running idle.

[0134] In one embodiment, the controller is configured to turn the light on or off in response to an operation of the operating unit when the trigger is pressed to at least a first predetermined stroke. In another embodiment, the controller is configured to turn the light on or off in response to an operation of the operating unit when the trigger is pressed to at least a second predetermined stroke. That is, the operation of the operating unit 120 to turn the light 800 on or off is performed when the power tool 1 is in a driven state.

[0135] The first and second pre-booked itineraries can be fixed values ​​or ranges, depending on the actual situation.

[0136] Of course, in an optional embodiment, the power tool can be powered on and enter the drive state simultaneously.

[0137] In this embodiment, since the motor 220 is in a drive preparation or driven state when the trigger 310 is pressed to a predetermined stroke, the lighting lamp 800 can be turned on or off by operating the operation unit 120 or the lighting control unit 180. This allows for accurate adjustment of ambient brightness according to the actual working environment of the power tool 1, thereby improving the user experience.

[0138] Specifically, in this embodiment, the power tool 1 has a memory function. If the light 800 was on when the power tool 1 was last used, then when the power tool 1 is used this time, pressing the trigger 310 will turn on the light 800 when the power tool 1 is powered on. If the ambient light is too bright or the object being operated on is a highly reflective metal plate, the operating unit 120 can be operated to turn off the light 800, thus avoiding power loss and interference from reflected light. Conversely, if the light 800 was off when the power tool 1 was last used, pressing the trigger 310 will turn on the light 800 when the power tool 1 is powered on. If the ambient light is too dim to work, the operating unit 120 can be operated to turn on the light 800.

[0139] In this embodiment, the operation configuration of the operation unit 120 is to turn on the operation unit 120, and the controller 700 is configured to control the lighting lamp 800 to turn on or off after receiving the signal that the operation unit 120 is turned on.

[0140] In another embodiment, the operation configuration of the operation unit 120 is to turn on the operation unit 120 and hold it for a third preset time, and then turn off the operation unit 120. The controller 700 is configured to control the lighting lamp 800 to turn on or off after receiving the signal that the operation unit 120 is turned on or off.

[0141] In one embodiment, the operation unit 120 is configured to be turned on N times within a set time period, and the controller 700 is configured to control the lighting lamp 800 to turn on or off after receiving the signal that the operation unit 120 has been turned on N times within the set time period, wherein N is a positive integer greater than or equal to 2.

[0142] The specific configuration of the operation unit 120 is not limited here, but is intended to make it convenient and simple for users to use the power tool 1 when performing operations.

[0143] Next, participants Figure 11 As shown, this embodiment illustrates the control system's control of the lighting lamp 800 and the switching of its operating modes.

[0144] First, in step S10, it is determined whether the trigger 310 has been pressed to a predetermined stroke. In this step, the CPU 721 detects the pressing signal of the trigger 310. Furthermore, in the following method, all determination steps are performed by the controller 700, specifically by the CPU 721 within the controller 700.

[0145] When it is determined that the trigger 310 has been pressed to a predetermined stroke, the process proceeds to step S20. In step S20, it is determined whether the operation unit 120 is activated, and if it is determined that the operation unit 120 is activated, the process proceeds to step S30. Furthermore, if it is determined in step S20 that the operation unit is not activated, the process returns to S10, and the determination of whether the trigger 310 has been pressed to a predetermined stroke is repeated.

[0146] In step S30, it is determined whether the lighting lamp 800 is on. If it is determined that the lighting lamp 800 is on, the process proceeds to step S40, where the controller 700 turns off the lighting lamp 800. Then, the process returns to step S10, and the above steps are repeated from step S10. If it is determined in step S30 that the lighting lamp 800 is not on, the process proceeds to step S50, where the controller 700 turns on the lighting lamp 800. Then, the process returns to step S10, and the above steps are repeated from step S10.

[0147] Continue to participate Figure 11As shown, if in step S10 it is determined that the trigger 310 has not been pressed to the predetermined stroke, the process proceeds to step S60 to determine whether the power tool 1 is in standby mode. If the power tool 1 is in standby mode, the process proceeds to step S70. In step S70, it is determined whether the operation unit 120 is turned on. If the operation unit 120 is turned on, the process proceeds to step S80. In step S80, the working mode is switched according to the way the operation unit 120 is turned on as described above, and the lighting 800 is turned off regardless of whether the lighting 800 is on or off, in order to avoid excessive energy consumption. Then, the process returns to step S10 and continues to repeat the above steps from step S10. Furthermore, if in step S60 it is determined that the power tool 1 is not in standby mode, and in step S70 it is determined that the operation unit 120 is not turned on, the process returns to step S10 and continues the above steps.

[0148] In the above embodiments, the same operation unit 120 is used to switch the working mode in standby mode and to control the lighting to turn on or off when the trigger 310 is pressed to a predetermined stroke. In optional embodiments, the switching of the lighting 800 on and off can also be controlled without the operation unit 120.

[0149] like Figure 12 As shown, the operation panel 100 also includes a lighting control unit 180. The lighting control unit 180 can be operated independently to turn the lights on and off when the trigger 310 is pressed to a predetermined stroke. The operation unit 120 can be used to switch operating modes in standby mode. Furthermore, when the trigger 310 is pressed to a predetermined stroke, the operation can also be performed as described above. Figure 11 The operation and control method shown performs the operation of turning the lighting lamp 800 on or off. The operation and control method in this embodiment is largely the same as in the above embodiments, with the difference being: "In step S20, is it determined whether the lighting control unit 180 is on?" and in step S70, is it determined whether the lighting control unit 180 is on? If the determination is yes, then proceed to step S80, in which the lighting lamp 800 is turned off. Furthermore, in step S70, it can also be determined whether the operation unit 120 is on. If it is on, then the operation mode is switched. If not, return to step S10 and repeat the above steps. In addition, in this embodiment, the method of operating the lighting control unit 180 is the same as the operation described above, and will not be repeated here.

[0150] In addition, further participation Figure 12As shown, in this embodiment, the operation panel 100 further includes a fourth region 114, the operation unit 120 is located in the first region 111, the lighting control unit 180 is located in the fourth region 114, and the first region 111, the second region 112, the third region 113 and the fourth region 114 are arranged in a straight line along the Y direction. The operation unit 120 and the lighting control unit 180 are located on both sides of the main light-emitting unit 130 and the secondary light-emitting unit 150.

[0151] In one embodiment, the power tool also includes a fault state. A fault state refers to a state where the power tool 1 malfunctions and cannot operate. In this embodiment, when the trigger 310 is pressed to a predetermined stroke and the indicator light 800 flashes, it indicates that the power tool 1 is in a fault state. In this embodiment, the fault state may include faults such as the motor 220 failing to rotate, overcurrent, overvoltage, or low voltage in the battery pack 500. Furthermore, the controller 700 can detect and indicate the fault state in the power tool 1's driving state. For example, if the controller 700 detects a fault such as the motor 220 failing to rotate, overcurrent, or overvoltage in the power tool 1's driving state, it can indicate the fault by flashing the indicator light 800. The controller 700 can also detect and indicate the fault state in the power tool 1's standby state. For example, if the controller detects a fault such as low voltage in the battery pack 500, it can indicate the fault by flashing the indicator light 800.

In the description of this invention, "at least two" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0155] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0156] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0157] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
