Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] As mentioned in the background section, power tools in related technologies often fail to clearly display their working status. The inventors have discovered that as power tools become smaller and lighter, it becomes increasingly difficult for users to obtain information about their operation.

[0044] For the purposes described above, in one aspect, one or more embodiments and combinations thereof of this specification provide a power tool 100. As an example, the power tool 100 may include an electric wrench, an electric angle grinder, an electric drill, or an electric cutter, etc.

[0045] Please see Figures 1 to 3 The power tool 100 includes a main housing 1, a motor 2, a transmission mechanism 3, a main handle 4, a secondary handle 5, and an output shaft 9. The main housing 1 extends in a front-to-back direction, and the motor 2 and the transmission mechanism 3 are located within the main housing 1. As an example, the transmission mechanism 3 includes an impact mechanism. The motor 2, the transmission mechanism 3, and the output shaft 9 are distributed sequentially from back to front. The front of the main housing 1 is used to connect the tool head.

[0046] The motor 2 is used to output rotational driving force, and the transmission mechanism 3 is used to transmit the output torque of the motor 2 to the output shaft 9. Then, the tool head (such as a drill bit) is driven to rotate through the output shaft 9 to perform the operation.

[0047] The main handle 4 is connected to the lower part of the main body housing 1 and extends in the vertical direction. As an example, the vertical direction is perpendicular to the front-back direction.

[0048] The auxiliary handle 5 is located in front of the main handle 4. For example, the auxiliary handle 5 can be located directly in front of the main handle 4, making the overall structure of the power tool 100 more symmetrical and aesthetically pleasing. Furthermore, both the main handle 4 and the auxiliary handle 5 have symmetrical structures, which helps to improve the appearance.

[0049] The top of the secondary handle 5 is connected to the main body housing 1, and the bottom of the secondary handle 5 is connected to the main handle 4. The secondary handle 5 and the main handle 4 cooperate to allow the user to hold it with both hands.

[0050] A trigger 40 is provided on the side of the main handle 4 facing the secondary handle 5. The trigger 40 can be used to start the power tool 100. As an example, under normal circumstances, the user usually uses his right hand to hold the main handle 4 for operation. Furthermore, when moving the power tool 100, the user usually uses his left hand to hold the secondary handle 5, thereby avoiding accidental activation of the trigger 40.

[0051] The secondary handle 5 includes a gripping part 51 and a mounting part 52 that are sequentially distributed and connected to each other in the vertical direction.

[0052] The grip portion 51 is used for user gripping. As an example, under normal circumstances, the user typically uses their right hand to grip the main handle 4 and their left hand to grip the grip portion 51, thereby maintaining the stability of the power tool 100. Furthermore, the dimension of the grip portion 51 in the left-right direction is between 4.0cm and 6.0cm, and / or the dimension of the grip portion 51 in the vertical direction is between 5.0cm and 8.0cm, thus facilitating user operation. The left-right direction is perpendicular to the vertical direction, and the vertical direction is perpendicular to the front-back direction. The above data are for illustrative purposes only; in actual embodiments, the dimensions of the grip portion 51 in the left-right direction and the vertical direction are not limited to the above data.

[0053] The mounting part 52 is used to connect the grip part 51 and the main handle 4. Specifically, the mounting part 52 is located below the grip part 51, the top of the grip part 51 is connected to the main body housing 1, and the bottom of the mounting part 52 is connected to the main handle 4. In this way, when the user holds the grip part 51, the user's hand can be supported on the bottom of the main body housing 1, making it easy to hold.

[0054] As an example, the dimension of the gripping part 51 in the left-right direction is smaller than the dimension of the mounting part 52 in the left-right direction. Figure 3 As shown, the mounting portion 52 has a first narrowing section 521, the dimension of which gradually decreases in the left-right direction toward the grip portion 51. One end of the first narrowing section 521 near the main body housing 1 is connected to the grip portion 51. For example, the angle between the connection point of the first narrowing section 521 and the grip portion 51 is α, and 15°≤α≤45°. The above data is for illustrative purposes only; in actual embodiments, the angle between the connection point of the first narrowing section 521 and the grip portion 51 is not limited to the above data.

[0055] In this example, the angle between the connection point of the first narrowing segment 521 and the gripping part 51 is defined as α, which is greater than or equal to 15° and less than or equal to 45°. This ensures that the size difference between the gripping part 51 and the mounting part 52 in the left-right direction is large, thereby reducing the size of the gripping part 51 in the left-right direction, so that the gripping part 51 can be made smaller for easier gripping.

[0056] The thickness of the grip portion 51 in the front-to-back direction can be less than the thickness of the mounting portion 52 in the front-to-back direction, further reducing the thickness of the grip portion 51 and making it easier for the user to hold. It should be understood that the thickness of the grip portion 51 in the front-to-back direction refers to the distance between the front and rear surfaces of the grip portion 51, and the thickness of the mounting portion 52 in the front-to-back direction refers to the distance between the front and rear surfaces of the mounting portion 52.

[0057] The power tool 100 may further include a removable battery housing 7 for housing a battery pack 81. The battery housing 7 is located below the main handle 4 and the auxiliary handle 5. Further, as... Figure 1 and Figure 2 As shown, a circuit board housing 41 is formed at the bottom of the main handle 4. The circuit board housing 41 is connected to the battery housing 7 and is used to house the battery circuit board 82.

[0058] The power tool 100 may also include a display screen 6. The display screen 6 is mounted on the side of the mounting part 52 facing the main handle 4. The display screen 6 is used to display the current usage information of the power tool 100 to the user, such as the remaining battery power, the operating temperature of the motor 2, the current gear, and the connection status with external devices (e.g., WiFi, Bluetooth connection, etc.).

[0059] The display screen 6 can be located close to the battery housing 7, and is powered by the battery pack 81. This allows for a smaller distance between the display screen 6 and the battery pack 81, as well as between the battery circuit board 82 and the display screen 6, facilitating their electrical connection. Simultaneously, the bottom of the mounting part 52 is connected to the front side of the circuit board housing 41, making it easy for the wiring harness of the display screen 6 to pass through the connection between the mounting part 52 and the circuit board housing 41 and then electrically connect to the battery circuit board 82, simplifying the wiring harness connection process.

[0060] In addition, a surrounding light-shielding film or the like can be provided on the surface of the display screen 6, thereby increasing the display effect of the power tool 100.

[0061] The power tool 100 also includes control keys 10. The control keys 10 may also be press keys, touch keys, or levers, etc.

[0062] Users can adjust the functions of the power tool 100 by operating the control key 10. Specifically, the control key 10 is used to control the motor 2 and the lighting accessory. As an example, the lighting accessory can be located on the front side of the auxiliary handle 5. Multiple light bulbs can be installed in the lighting accessory.

[0063] For details, please refer to Figure 4The power tool 100 may include a control device, and the control keys 10 (e.g., first button 110 and second button 120), the lighting accessory, the display screen 6, and the motor 2 can all be connected to the control device. For example, when the control key 10 is triggered, the control device receives a corresponding signal and controls one or more of the display screen driver module, the motor driver module, and the lighting accessory to react accordingly. Specifically, in response to the triggering of the first button 110 and the second button 120, the display screen driver module drives the display screen 6 to display corresponding icons and / or values, and the motor driver module starts the motor 2 by driving a three-phase inverter, so that the motor 2 has a corresponding operating current or speed, etc.

[0064] In one possible example, please see Figure 3 The control key 10 may include a first button 110 and a second button 120. The first button 110 and the second button 120 can be used together to control the power tool 100, or the first button 110 and the second button 120 can be used individually to control the power tool 100.

[0065] Of course, the control key 10 may also include more control keys. For example, a third control key, a fourth control key, etc.

[0066] For further details, please refer to Figure 3 The first button 110 and the second button 120 can be located on the side of the display screen 6 near the bottom of the secondary handle 5, so that when the user operates the first button 110 and the second button 120, he / she can quickly observe the operation result on the display screen 6.

[0067] In one embodiment, see Figure 5 In Figure (A), the display screen 6 has a second narrowing segment 61 and a main display segment 62. The second narrowing segment 61 corresponds to the position of the first narrowing segment 521, and the second narrowing segment 61 gradually narrows along the contour of the first narrowing segment 521.

[0068] The main display section 62 is connected to the side of the second narrowing section 61 near the bottom of the auxiliary handle 5, and the size of the main display section 62 in the left-right direction is not less than the maximum size of the first narrowing section 521 in the left-right direction.

[0069] In one possible example, the main display segment 62 has the same dimensions in the left-right direction. As an example, the main display segment 62 can be rectangular, and the second narrowing segment 61 can be a trapezoid. Furthermore, the base of the trapezoid can be the same length as the rectangle.

[0070] In another possible example, the size of the main display segment 62 in the left-right direction can vary. As an example, the size of the main display segment 62 in the left-right direction can gradually increase in the direction close to the battery housing 7. For example, the main display segment 62 can extend to the side wall of the mounting portion 52, or even extend to the side of the mounting portion 52 opposite to the main handle 4.

[0071] In yet another possible example, please refer to Figure 5 In Figure (B), the sides of the second narrowing segment 61 and / or the main display segment 62 may be curved or approximately arc-shaped, thereby allowing the display screen 6 to have different shapes to adapt to different models of the power tool 100.

[0072] In addition, please refer to other embodiments. Figure 5 As shown in Figure (C), the shape of the display screen 6 may also include an octagon, etc. It can be understood that, in addition to the second narrowing segment 61 and the main display segment 62, the shape of the display screen 6 provided in this embodiment may also include a centrally symmetrical shape or an axisymmetric shape, etc.

[0073] In one embodiment, the area of ​​the display screen 6 may be no less than 20 cm². 2 For example, the display screen 6 can have the same area as the side of the mounting part 52 facing the main handle 4, thereby maximizing the display area of ​​the display screen 6 and facilitating the user's observation of the displayed content. Therefore, the area of ​​the display screen 6 can be no less than 20 cm². 2 For example, the area of ​​the display screen 6 can be 2178.7 mm². 2 .

[0074] Furthermore, the area of ​​the display screen 6 may not exceed 65 cm². 2 For example, the area of ​​the display screen 6 can be 6155.63 mm². 2On the one hand, the inventors believe that the second narrowing segment 61 and the first narrowing segment 521 can have the same dimensions in the left-right direction, and their dimensions can be related to the average length of the thumb (for example, the left-right dimension of the grip portion 51 is between 4.0cm and 6.0cm), thus ensuring that the width of the grip portion 51 is not too large, which is beneficial for the user to grasp the grip portion 51. On the other hand, the inventors believe that in the vertical direction, the height of the grip portion 51 can be related to the average width of the palm (for example, the vertical dimension of the grip portion 51 is between 5.0cm and 8.0cm), thus ensuring that the user can grasp the grip portion 51. At the same time, in order to prevent the palm from obstructing the display screen 6 and to maintain the stability of the power tool 100, it is necessary to limit the height of the display screen 6 in the vertical direction, that is, the height of the display screen 6 in the vertical direction should not be too high. Therefore, the area of ​​the display screen 6 can be no greater than 65cm². 2 .

[0075] In this embodiment, firstly, the display screen 6 is formed on the secondary handle 5, and the display screen 6 has a second narrowing section 61 and a main display section 62, so that the display screen 6 has a large display area (for example, the area of ​​the display screen 6 can be not less than 20cm²). 2 This design facilitates user observation of the content displayed on the display screen 6. Furthermore, the contour of the second narrowing segment 61 of the display screen 6 matches the contour of the first narrowing segment 521 of the mounting portion 52, allowing the display screen 6 to fully utilize the installation space of the mounting portion 52 and extending the vertical dimension of the display screen 6, providing the visual impression of a large display screen. Moreover, the display screen 6 places different icons and values ​​in different areas, thereby allowing more important values ​​(e.g., torque values) to have a larger display area, making these important values ​​more intuitively displayed.

[0076] In one embodiment, such as Figure 1 and Figure 2 As shown, the mounting portion 52 is inclined towards the front of the power tool 100 in an upward direction, so that the display screen 6 is inclined in the same or similar direction. That is, at this time, the distance between the second narrowing section 61 and the main handle 4 is greater than the distance between the main display section 62 and the main handle 4.

[0077] The inventors discovered that when a user uses the power tool 100, the power tool 100 is often below eye level. Therefore, in this embodiment, by tilting the display screen 6, it is easier for the user to easily view the display screen 6 while operating the power tool 100.

[0078] In one embodiment, the display screen 6 includes a display panel, a cover plate, and a light strip.

[0079] The cover plate covers the display panel and is located on the side of the display panel closer to the main handle 4. As an example, the cover plate can be made of glass, plastic, or other materials.

[0080] The light strip can be located between the cover plate and the display panel, and surrounds the display panel. When the power tool 100 is started, the light strip lights up, thereby increasing the brightness of the display screen 6 and making it easier for users to observe the information displayed on the display screen 6 in low-light environments.

[0081] Furthermore, when the power tool 100 is powered on, the light strip can be illuminated in a ring. Correspondingly, when the power tool 100 is powered off, the light strip can be extinguished in a ring.

[0082] In one embodiment, the display screen 6 may further include a display circuit board. The display circuit board may be housed within the mounting portion 52. The display panel is mounted on the display circuit board and electrically connected to it. It is understood that the display panel is used to display information, and the display circuit board may be provided with circuitry for controlling the display panel to display the corresponding information.

[0083] Furthermore, the area of ​​the display circuit board is not less than 35 cm². 2 And / or, the area of ​​the display panel is not less than 20 cm². 2 And / or, the area of ​​the cover plate is not less than 40 cm². 2 For example, the area of ​​the display circuit board can be 3263.7 mm². 2 The area of ​​the cover plate can be 3866.9 mm². 2 The above data are for illustrative purposes only. In actual embodiments, the area of ​​the display circuit board, the area of ​​the cover plate, and the area of ​​the display panel are not limited to the above data.

[0084] The shapes of the display circuit board, the display panel, and the cover plate can match the shape of the display screen 6. For example, the shapes of the display circuit board, the display panel, and the cover plate can all be narrower at the top and wider at the bottom.

[0085] In one embodiment, see Figures 5 to 7 The display screen 6 is configured to display a variety of icons and numerical values. For example, the display screen 6 can display at least three different icons, or it can display at least three numerical values.

[0086] In one possible example, please see Figure 6The icon may include a gear icon 63 for displaying the current gear position of the power tool 100 in normal mode, and / or the icon may include a smart icon 64 for displaying whether the power tool 100 is in smart mode (in smart mode, the motor 2 stops working when the power tool 100 reaches a preset condition), and / or the icon may include a connection icon 65 (e.g., WiFi or Bluetooth) for displaying whether the power tool 100 is in connection mode (in connection mode, the power tool 100 is connected to an external device), and / or the icon may include a high temperature icon for displaying whether the power tool 100 is overheating, and / or the icon may include a warning icon for displaying whether the power tool 100 is in an error mode, etc.

[0087] In another possible example, see Figure 6 The values ​​may include a torque value 66 for real-time display of the torque parameters of the power tool 100, and / or, a custom value 67 for the power tool 100 to customize preset parameters, and / or, a count value 68 for displaying the counting result of the power tool 100, and / or, a temperature value for displaying the current temperature of the power tool 100, and / or, a code value for displaying the error code of the power tool 100, and / or, a power value for displaying the current battery level of the power tool 100, etc.

[0088] The icons and values ​​are illustrated below. It should be understood that the following is merely illustrative and does not limit the scope of this specification.

[0089] The gear icon 63 can be used to display the current gear of the power tool 100. For example, please refer to... Figures 9 to 11 The gear position icon 63 can be in the form of L (Light), M (Middle), H (High), etc. It can be understood that the L, M, H, etc. forms displayed by the gear position icon 63 correspond to the working state of the motor 2.

[0090] The smart icon 64 can be used to indicate whether the power tool 100 is in smart mode. For example, when the smart icon 64 is lit, it indicates that the power tool 100 is in smart mode. When the smart icon 64 is off, it indicates that the power tool 100 is not in smart mode.

[0091] Furthermore, when the power tool 100 is an electric wrench, in the intelligent mode, the electric wrench automatically stops working when it detects that a bolt is tightened. Alternatively, the electric wrench automatically stops working when it detects that a bolt is loose. Of course, whether the bolt is tightened (forward rotation) or loosened (reverse rotation) can be determined by the torque value or the current value. As an example, in the L gear of the intelligent mode, forward rotation stops after an impact is detected, and reverse rotation stops after unloading is detected. In the M gear of the intelligent mode, forward rotation stops 0.5 seconds after an impact is detected, and reverse rotation stops 0.2 seconds after unloading is detected. In the H gear of the intelligent mode, forward rotation stops 1 second after an impact is detected, and reverse rotation reduces the speed to 210 RPM and maintains rotation after unloading is detected.

[0092] The connection icon 65 can be used to indicate whether the power tool 100 is connected to an external device. For example, when the connection icon 65 is lit, it indicates that the power tool 100 is connected to an external device. When the connection icon 65 is off, it indicates that the power tool 100 is disconnected from the external device. External devices may include, but are not limited to, smartphones, smartwatches, tablets, desktop computers, wearable devices, and IoT devices. For example, when the connection icon 65 is lit, the user can set the parameters of the power tool 100 on the external device (e.g., a mobile phone), or the user can view information about the power tool 100 on the external device (e.g., a mobile phone).

[0093] The torque value 66 can be used to display the current torque of the power tool 100 in real time. As an example, the torque value 66 may include four digits. Furthermore, the torque value 66 may also include torque units (Nm).

[0094] The custom value 67 can be used to display the result of the power tool 100 custom setting of preset parameters (e.g., torque). For example, when the torque required by the user differs significantly from the preset gear (e.g., L, M, H), the user can set it manually. In this case, the set value can be displayed through the custom value 67.

[0095] The count value 68 can be used to display the number of bolts tightened / loosened by the power tool 100 (e.g., an electric wrench), or it can be used to display the working time of the power tool 100. Of course, when the power tool 100 is an electric wrench, the count value 68 can be used in both forward and reverse rotation.

[0096] It is understood that the icons and values ​​of the power tool 100 provided in this specification are not limited to the examples above.

[0097] Furthermore, the icons and values ​​provided in this specification can have various lighting modes. For example, the icons and values ​​can remain constantly lit, or they can blink, or they can light up dynamically (e.g., lighting up clockwise), etc.

[0098] Similarly, the icons and values ​​provided in this specification can have various off states. The off states of the icons and values ​​are similar to the on states of the icons and values, and will not be described in detail here.

[0099] Please see Figure 7 In (A), the display screen 6 has an upper display area 603 and a lower display area 604 distributed in the vertical direction. The upper display area 603 is located within the second narrowing segment 61, and the lower display area 604 may be at least partially located within the main display segment 62. The size of the upper display area 603 in the horizontal direction is smaller than the size of the lower display area 604 in the horizontal direction, so that the content displayed on the display screen 6 is distributed to match the shape of the display screen. As an example, the upper display area is used to display at least some icons, and the lower display area is used to display at least some numerical values. It can be understood that the icons are located within the second narrowing segment 61, and the numerical values ​​are at least partially located within the main display segment 62.

[0100] For details, please refer to Figure 5 The gear position icon 63, the smart icon 64, the connection icon 65, and the custom value 67 can all be located within the upper display area 603. Correspondingly, the torque value 66 and the count value 68 can be partially located within the upper display area 603 and partially within the lower display area 604. As an example, the display area of ​​the gear position icon 63, the smart icon 64, the connection icon 65, and the custom value 67 can be relatively small, while the display area of ​​the torque value 66 and the count value 68 can be relatively large.

[0101] The inventors discovered that users can quickly obtain relevant information about the power tool 100 by observing the lit or unlit states of the gear position icon 63, the smart icon 64, and the connection icon 65. The torque value 66 is displayed in multi-digit form, which means that the time it takes for the user to know the torque value 66 is longer than the time it takes for the gear position icon 63, the smart icon 64, and the connection icon 65 to be lit or unlit. Therefore, by enlarging the size of the torque value 66, users can quickly and clearly obtain real-time torque information.

[0102] Furthermore, the gear position icon 63 and the torque value 66 can be arranged sequentially in the vertical direction. The current gear position and real-time torque value of the power tool 100 are important information. Therefore, displaying the gear position icon 63 and the torque value 66 sequentially makes it easier for users to quickly obtain gear and torque information.

[0103] In another possible case, please see Figure 7 In section (B), in the direction from left to right, the display screen 6 has a first display area 601 and a second display area 602 that are continuously arranged. The first display area 601 is configured to display at least the gear icon 63 and the torque value 66 of the power tool 100, and the second display area 602 is configured to display at least the count value 68 of the power tool 100.

[0104] Of course, the first display area 601 can also be configured to display the smart icon 64, and the second display area 602 can be configured to display the custom value 67. The connection icon 65 can be located in either the first display area 601 or the second display area 602. Specifically, the smart icon 64 can be located on the side of the first display area 601 closer to the second display area 602.

[0105] The inventors discovered that, under normal circumstances, users typically hold the main handle 4 with their right hand, and when using the power tool 100, it often tilts to the left front to achieve balance. Therefore, by placing the gear icon 63 and the torque value 66 in the first display area 601, users can quickly obtain important information. Simultaneously, by placing the count value 68 and the custom value 67, etc., in the second display area 602, the displayed content of the screen 6 can be more evenly distributed, allowing users to more clearly observe each icon or value.

[0106] Furthermore, in the direction from right to left, the display screen 6 also has a first display area 601 and a second display area 602 that are continuously arranged, thus adapting to users whose left hand is dominant.

[0107] Furthermore, the dimension of the mounting portion 52 in the left-right direction is larger than the dimension of the main handle 4 in the left-right direction. Specifically, the orthographic projection of the main handle 4 in the front-back direction partially overlaps with the orthographic projection of the display screen 6 in the front-back direction. Moreover, the display screen 6 also has a shielding area and an exposed area, with the exposed area located on both sides of the shielding area. At this time, in the positive direction of the front-back direction, the orthographic projection of the main handle 4 overlaps with the orthographic projection of the shielding area, and the first display area 601 at least partially overlaps with the exposed area.

[0108] In this configuration, the user can observe the first display area 601 from directly behind the power tool 100; that is, the user can observe at least a portion of the gear indicator 63 and the torque value 66 from directly behind the power tool 100. By placing the gear indicator 63 and the torque value 66 in the exposed area on the left side, the area where the user's view is obstructed by the main handle 4 when viewing the display screen 6 is reduced.

[0109] Simultaneously, the first button 110 in the control keys can be placed near the first display area, and in response to the triggering of the first button 110, the current operating parameters displayed in the first display area 601 of the display screen 6 change. This allows the user to quickly obtain the parameters or parameter values ​​of the current operating parameters of the power tool 100 from the first display area 601 when pressing the first button 110, thereby improving the efficiency of using the power tool 100. As an example, the operating parameters may include, but are not limited to, duty cycle, current, etc.

[0110] Specifically, in the forward direction, the orthographic projection of the first button 110 does not completely overlap with the orthographic projection of the main handle 4. This allows the user to obtain the current operating parameters of the electrician tool 100 from the first display area 601 when operating the first button 110 from multiple angles. For example, when the user presses the first button 110 from an oblique angle (e.g., 45°), the area of ​​the main handle 4 obstructing the first display area 601 is small.

[0111] In one embodiment, see Figure 8 The power tool 100 has multiple working positions (e.g., L, M, H), and correspondingly, the position icon 63 has multiple forms. By setting the arrangement and on / off state of the display tubes of the display screen 6, a single position icon 63 can be displayed in multiple forms.

[0112] Specifically, the gear indicator 63 includes a basic display tube group 631 and an extended display tube group 632. It can be understood that both the basic display tube group 631 and the extended display tube group 632 can be digital tubes. The extended display tube group 632 is used in conjunction with the basic display tube group 631 to display multiple light-emitting combinations, which correspond to the working gear position.

[0113] The basic display tube assembly 631 may include a plurality of first display tubes 6311 extending along a first direction (e.g., the X-axis direction, or the horizontal direction, or the left-right direction), and a plurality of second display tubes 6312 extending along a second direction (e.g., the Y-axis direction, or the vertical direction, or the up-down direction). The first direction is perpendicular to the second direction.

[0114] The plurality of first display tubes 6311 and the plurality of second display tubes 6312 enclose a continuously arranged first region (e.g., Figure 8 Region A in the middle) and Region B (e.g., Figure 8 (Region B in the text). It can be understood that there are no other first display tubes 6311 and second display tubes 6312 in either the first or second region.

[0115] The extended display tube assembly 632 may include at least one third display tube 6321 extending along a third direction and at least one fourth display tube 6322 extending along a fourth direction. The third display tube 6321 and the fourth display tube 6322 are located within one of the first region or the second region. As an example, the third display tube 6321 and the fourth display tube 6322 may be located in the upper region of both the first and second regions. The third direction is inclined relative to both the first and second directions, the fourth direction is inclined relative to both the first and second directions, and the third direction is mirror-image (symmetrical) to the fourth direction.

[0116] The first display tube 6311, the second display tube 6312, the third display tube 6321 and the fourth display tube 6322 can be selectively activated to form multiple light-emitting combinations, and the light-emitting combinations correspond to the working positions.

[0117] In one possible example, selectively activating multiple first display tubes 6311 and multiple second display tubes 6312 can display the letter L ( ). Figure 9 (as shown) and H ( Figure 10 (As shown).

[0118] In another possible example, the plurality of first display tubes 6311 include a designated display tube shared by the first region and the second region. One end of the third display tube 6321 is close to the fourth display tube 6322 and also close to the designated display tube, while one end of the fourth display tube 6322 is close to the third display tube 6321 and also close to the designated display tube. In this case, the first display tubes 6311, the second display tube 6312, the third display tube 6321, and the fourth display tube 6322 can be selectively activated to form the letter M (…). Figure 11 (As shown).

[0119] At this time, the lengths of the third display tube 6321 and the fourth display tube 6322 are less than the length of the first display tube 6311, and / or, the lengths of the third display tube 6321 and the fourth display tube 6322 are less than the length of the second display tube 6312. And / or, the included angle formed by the third display tube 6321 and the fourth display tube 6322 is an acute angle, thereby allowing the letter M to be displayed more clearly.

[0120] In another possible example, the plurality of first display tubes 6311 include a designated display tube shared by the first region and the second region. One end of the third display tube 6321 is close to the fourth display tube 6322 while being away from the designated display tube, and one end of the fourth display tube 6322 is close to the third display tube 6321 while being away from the designated display tube. In this case, the first display tubes 6311, the second display tube 6312, the third display tube 6321, and the fourth display tube 6322 can be selectively activated to form the letter A.

[0121] In this embodiment, multiple different gear position icons 63 can be formed by turning multiple display tubes on or off. Specifically, in this embodiment, by setting a basic display tube group 631 and an extended display tube group 632, at least the letters L, M, and H can be displayed within the display range of the same gear position icon 63, thereby reducing the area of ​​the gear position icon 63.

[0122] In one embodiment, see Figure 12 The first display tube 6311 includes a first tube (e.g., Figure 12 Pipe A in the middle), the second pipe (for example, Figure 12 (e.g., tube B in the middle), the third tube (e.g., Figure 12 (C tube in the middle) and the fourth tube (e.g., Figure 12 (D-tube in the example). The first tube and the second tube are arranged consecutively, the third tube and the fourth tube are arranged consecutively, the first tube and the third tube are arranged opposite each other, the second tube and the fourth tube are arranged opposite each other, the first tube and the second tube are turned on or off based on the same control signal, and the third tube and the fourth tube are turned on or off based on the same control signal.

[0123] Furthermore, the second display tube 6312 includes a fifth tube arranged in parallel (e.g., Figure 12 (e.g., tube E) and tube six (e.g., Figure 12 The fifth and sixth transistors are turned on or off based on different control signals (F transistor in the transistor).

[0124] In this embodiment, the control logic is simplified by setting the first and second transistors to be lit or turned off based on the same control signal, and the third and fourth transistors to be lit or turned off based on the same control signal.

[0125] In this embodiment, the basic display tube group 631 and the extended display tube group 632 can also display other letters, numbers, or patterns. The following exemplifies the arrangement of the basic display tube group 631 and the extended display tube group 632 in this embodiment. It should be understood that the form of the gear icon 63 described below does not indicate the scope of protection of this embodiment.

[0126] In a first possible embodiment, one of the first region and the second region has an opening. As an example, the upper one of the first region and the second region has an opening.

[0127] The inventors discovered that in conventional gear positions (L, M, H), the top area of ​​either the first or second region is not required. Therefore, a display tube can be omitted in this location.

[0128] In a second possible embodiment, the third display tube 6321 and the fourth display tube 6322 are located within the region having the opening. As an example, the uppermost of the first region and the second region has an opening, in which case the letter M can be better displayed within the region of the uppermost of the third display tube 6321 and the fourth display tube 6322.

[0129] In a third possible embodiment, the third display tube 6321 and the fourth display tube 6322 may be located in an area without openings. For example, if the upper part of the first and second areas has an opening, then the lower part of the third display tube 6321 and the fourth display tube 6322 may form the letter V.

[0130] In a fourth possible example, both the first and second regions are closed areas. In this case, the letter O or the number 8, etc., can be displayed.

[0131] In the fifth possible example, please see Figure 12 The extended display tube group 632 further includes a fifth display tube 6323, which is located beside the first region or the second region. As an example, the fifth display tube 6323 can be circular.

[0132] Furthermore, the length of the fifth display tube 6323 is less than the lengths of the third display tube 6321 and the fourth display tube 6322. In this case, the fifth display tube 6323 can be located in the lower right corner of the gear indicator 63. As an example, when the fifth display tube 6323 is lit, the power tool 100 can rotate forward; when the fifth display tube 6323 is off, the power tool 100 can rotate in reverse.

[0133] In one embodiment, see Figure 13 The control key 10 may include a first button 110 and a second button 120. The user can then operate the power tool 100 by pressing the first button 110 and the second button 120. Specifically, the control device is configured to perform the following steps:

[0134] Step S10: In response to the first preset condition triggering of the first button 110, switch the operating parameters of the power tool 100.

[0135] The preset condition may include the duration of button press, or the preset condition may include the pressure applied to the button. In step S10, as an example, the first preset condition of the first button 110 may be that the first button 110 is pressed for a first duration (e.g., 3 seconds).

[0136] Please see Figure 14 When the control device receives a signal that the first preset condition of the first button 110 has been triggered, it can switch the display of the power tool 100's operating mode on the display screen 6. For example, the operating mode may include a normal mode, a smart mode, a connection mode, and a custom mode.

[0137] Specifically, the gear icon 63, smart icon 64, and custom value 67 on the display screen 6 can switch between flashing and being lit.

[0138] Step S20: In response to the triggering of the second preset condition of the second button 120, switch the working state of the power tool accessory.

[0139] In step S20, the second preset condition of the second button 120 can be the second pressing duration of the second button 120 (e.g., 3s).

[0140] The accessories for the power tool 100 may include, but are not limited to, lighting accessories. Please refer to [link / reference]. Figure 16When the control device receives a second preset condition trigger from the second button 120, it can either turn the lighting accessory on or off. Furthermore, the lighting accessory can be timed after being turned on. For example, the lighting accessory can automatically turn off after 15 seconds to avoid wasting power. Alternatively, while the lighting accessory is on, it can be turned off when the control device receives a second preset condition trigger from the second button 120. Conversely, while the lighting accessory is off, it can be turned on when the control device receives a second preset condition trigger from the second button 120.

[0141] Step S30: In response to the third preset condition of the first button 110 and the fourth preset condition of the second button 120, adjust the operating parameters of the power tool 100.

[0142] In step S30, as an example, the third preset condition of the first button 110 can be that the first button 110 is pressed for a third pressing duration (e.g., 1 second). The fourth preset condition of the second button 120 can be that the second button 120 is pressed for a fourth pressing duration (e.g., 1 second).

[0143] For example, when the power tool 100 is in the custom mode, the operating parameters (impact duration or maximum torque value, etc.) of the power tool 100 can be increased or decreased by briefly pressing the first button 110 or the second button 120.

[0144] For example, please see Figure 15 The control device is also configured to perform the following steps:

[0145] Step S51: In response to the triggering of the third preset condition of the first button 110, reduce the operating parameters of the power tool 100.

[0146] Step S52: In response to the triggering of the fourth preset condition of the second button 120, increase the working parameters of the power tool 100.

[0147] As an example, when the operating parameter is the impact duration, a short press of the first button 110 reduces the impact duration by one second. A short press of the second button 120 increases the impact duration by one second. At this time, the display screen 6 can display the user's operation result in real time, thus confirming that the impact duration setting is complete.

[0148] In this embodiment, the first button 110 and the second button 120 can cooperate with each other to control the power tool 100, and the first button 110 and the second button 120 can also control the power tool 100 independently, thereby achieving flexible control of the power tool 100. At the same time, the number of control keys 10 is also small, so as to simplify the circuit, reduce costs, and make operation easier.

[0149] In one possible example, please see Figure 17 The control device is also configured to perform the following steps:

[0150] Step S40: In the normal mode, in response to the triggering of the third preset condition of the first button 110, the working gear of the power tool 100 in the normal mode is switched.

[0151] Step S41: In the intelligent mode, in response to the triggering of the third preset condition of the first button 110, the working gear of the power tool 100 in the intelligent mode is switched.

[0152] As an example, the third preset condition for the first button 110 can be that the first button 110 is pressed for 1 second.

[0153] In the normal mode, multiple working positions can be preset. For example, the normal mode can be set with three positions: L, M, and H, with the working time or maximum torque value increasing sequentially.

[0154] As mentioned above, in the intelligent mode, the motor 2 stops working when the power tool 100 meets a preset condition. When the power tool 100 is an electric wrench, the preset condition can be that the electric wrench automatically stops working when it detects that the bolt is tightened. Alternatively, the electric wrench automatically stops working when it detects that the bolt is loose.

[0155] When the normal mode or intelligent mode is selected, the power tool 100 can be switched between three gears (L, M, and H) by briefly pressing the first button 110. For example, at this time, the gear icon 63 on the display screen 6 can switch between the letters L, M, and H. Furthermore, at this time, the letters L, M, and H can be formed by selectively activating the first display tube 6311, the second display tube 6312, the third display tube 6321, and the fourth display tube 6322.

[0156] In another possible example, see Figure 18 The control device is also configured to perform the following steps:

[0157] Step S50: In response to the fifth preset condition triggering of the first button 110, control the power tool 100 to enter the counting mode.

[0158] In step S50, as an example, the fifth preset condition trigger of the first button 110 can be the fifth pressing duration of the first button 110 (e.g., 13s).

[0159] When the power tool 100 is in counting mode, the count value 68 may flash.

[0160] Step S52: In response to the second preset condition triggering of the second button 120, the count is reset to zero.

[0161] In step S52, as an example, the second preset condition trigger of the second button 120 can be that the second button 120 is pressed for 1 second.

[0162] When the count value 68 is cleared, the displayed value of the technical value is zero.

[0163] As mentioned above, the count value 68 can be used to represent the number of bolts tightened / loosened by the power tool 100 (e.g., an electric wrench). Specifically, the counting mode can include a forward counting mode and a reverse counting mode. Accordingly, the count value 68 can also include a forward counting value and a reverse counting value. The forward counting value and the reverse counting value can be arranged vertically.

[0164] At this point, after step S50, the following may be included:

[0165] Step S51: In response to the third preset condition triggering of the first button 110, switch between the forward counting mode and the reverse counting mode.

[0166] In step S51, the third preset condition for the first button 110 can be that the first button 110 is pressed for 1 second. When switching between the forward counting mode and the reverse counting mode, the forward counting value 68 and the reverse counting value 68 can flash alternately.

[0167] In one embodiment, see Figure 19 The control device is configured as follows:

[0168] Step 61: In response to the detection point of the first button 110 and / or the detection point of the second button 120 being at the first level, start timing.

[0169] In step 61, the first button 110 and the second button 120 can be electrically connected to corresponding detection points. When the first button 110 and / or the second button 120 is pressed, the corresponding detection point can receive the first voltage level. As an example, the first voltage level can be a high voltage level.

[0170] For example, when the first button 110 and / or the second button 120 is pressed, the circuit of the corresponding detection point can be turned on. Furthermore, this circuit can be connected to the input terminal (Vcc), at which point the corresponding detection point can have a high level. This embodiment does not limit the specific form of the circuit.

[0171] Step 62: Based on the duration of the first level, determine whether the preset condition trigger of the first button 110 and / or the second button 120 is triggered.

[0172] In step 62, when the first button 110 and / or the second button 120 is pressed, the corresponding detection point can receive the first level. Correspondingly, when the first button 110 and / or the second button 120 is released, the detection point changes from the first level to the second level. As an example, the second level can be a low level.

[0173] At this time, by obtaining the duration for which the detection point remains at the first level, it can be determined whether the preset conditions of the first button 110 and / or the second button 120 are triggered, thereby determining the user's intention.

[0174] Furthermore, prior to step 61, the following may be included:

[0175] Step 60: Poll to obtain the level of the detection point of the first button 110 and / or the detection point of the second button 120.

[0176] In step 60, as an example, the level of the detection point of the first button 110 and / or the detection point of the second button 120 can be polled every 5ms.

[0177] By polling to obtain the level of the detection point of the first button 110 and / or the detection point of the second button 120, the user's operation can be responded to quickly.

[0178] Based on the description of the method steps performed by the control device of the power tool 100 described above, this disclosure also provides a control device for the power tool 100. The device may include a system (including a distributed system), software (application), module, component, computer equipment, client, etc., using the methods described in the embodiments of this specification, combined with necessary hardware implementation. Based on the same innovative concept, since the implementation schemes and methods for solving the problem by the device are similar, the implementation of the specific device in the embodiments of this specification can be referred to the implementation of the foregoing method, and repeated details will not be elaborated further. The control device of the power tool 100 may include multiple "units" or "modules" to achieve a combination of software and / or hardware to realize a predetermined function. Although the embodiments described in this specification are implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0179] In one embodiment, the control device includes a receiving mode, a processing module, and an execution module. As an example, the receiving mode is used to receive preset conditions from the first button 110 and the second button 120. The processing module is used to determine an execution task based on the preset conditions. For example, the execution task may include resetting the counter, starting the lighting, switching working modes, etc. The execution module is used to send task information. As an example, the execution module may send start information to the lighting accessory, etc.

[0180] In one embodiment, the power tool 100 can display parameter values ​​(e.g., torque, pressure, speed, etc.) in real time. In this case, this embodiment provides a method for calculating the parameter values ​​of the power tool 100. The parameter value calculation method of the power tool 100 can also be executed by the control device. As an example, the power tool 100 includes an impact mechanism. The impact mechanism can generate intermittent rotational impact force on the output shaft of the power tool through motor output. For example, the power tool 100 may include an electric wrench. See also... Figures 20 to 22 The method for calculating the parameter values ​​of the power tool 100 may include the following steps:

[0181] Step S200: Obtain the usage time of the impact mechanism.

[0182] In step S200, the usage time of the impact mechanism can be the operating time of the motor 2. As an example, the usage time can be 1.0s, 5.3s, 8.7s, 10.4s, etc.

[0183] It is understood that when the power tool 100 is an electric wrench, the usage time in this embodiment does not refer to the total working time of the power tool 100, but rather to the working time of the motor 2 in that particular instance.

[0184] Furthermore, step S200 may include:

[0185] Step S210: Obtain the usage time of the impact mechanism at a second preset time interval.

[0186] In step S210, as an example, the second preset duration can be 100ms. At this time, the usage duration of the impact mechanism can be obtained by polling at shorter intervals, thereby achieving the purpose of calculating the parameter values ​​of the power tool 100 in real time.

[0187] Step S300: Based on the usage duration, determine the target time interval corresponding to the usage duration.

[0188] In step S300, multiple time intervals can be preset, and then the time interval into which the usage duration falls can be determined, which can be determined as the target time interval.

[0189] For example, please refer to Figure 20 and Figure 21 The time interval can be [0, 8000ms] and [8000ms, ∞]. When the usage duration is less than 8000ms, the target time interval can be [0, 8000ms]. When the usage duration is greater than or equal to 8000ms, the target time interval can be [8000ms, ∞]. The above data is for illustrative purposes only; in actual embodiments, the time interval is not limited to the above data.

[0190] Step S400: Obtain the time-parameter value function for the target time interval.

[0191] In step S400, each time interval can have a preset time-parameter value function. The time-parameter value function can be a time-torque function, etc. For example, the time-torque function for the interval [0, 8000ms] can be:

[0192] N = 231.6 * t + 356.61, t < 8000 ms

[0193] The time-torque function for the interval [8000ms, ∞] can be:

[0194] N = 20.945 * t + 1741.6, t >= 8000 ms

[0195] Where N can represent the torque value, and t can represent the usage duration. The above data is for illustrative purposes only; in actual embodiments, the time-parameter value function is not limited to the above data.

[0196] Step S500: Determine the parameter values ​​of the power tool 100 based on the usage duration and the time-parameter value function.

[0197] In step S500, the usage duration can be substituted into the time-parameter value function to calculate or find the parameter values ​​of the power tool 100 (e.g., torque value, pressure value, speed value, etc.).

[0198] Furthermore, the time-parameter value function can be a linear function, thereby improving the calculation speed of the parameter values ​​of the power tool 100. Of course, the time-parameter value function can also be a quadratic function, power function, exponential function, or logarithmic function, etc., to obtain more accurate calculation results. It is understood that the type of the time-parameter value function does not limit the scope of protection of this specification.

[0199] In this embodiment, by presetting multiple time intervals, and each time interval having a corresponding time-parameter value function, the parameter values ​​of the power tool 100 can be quickly calculated using the time-parameter value function. These parameter values ​​can then be displayed in real-time on the display screen 6 for easy user observation. Furthermore, this embodiment improves the calculation accuracy of each time-parameter value function by setting a corresponding time-parameter value function for each time interval.

[0200] In one possible example, please see Figure 22 Step S400 includes:

[0201] Step S410: Obtain the working gear of the power tool 100 in the current working mode.

[0202] In step S410, the power tool 100 may have multiple gear positions. For example, the power tool 100 may have a normal mode and a smart mode. Each mode may have three gear positions: L, M, and H. At this time, the operating gear position of the power tool 100 in the current operating mode can be determined by the control device.

[0203] Step S420: Obtain the time-parameter value function of the target time interval of the working gear.

[0204] In step S420, the working gears in different working modes have different time intervals, and each time interval has a different time-parameter value function. Therefore, the corresponding time-parameter value function can be determined based on the working gear in the current working mode.

[0205] In another possible example, before step S200, the following is included:

[0206] Step S100: Obtain the current value of the impact mechanism.

[0207] In step S100, a current sampling module can be installed between the motor 2 and the control device. This current sampling module can be used to collect the current value at the motor 2. For example, the current sampling module can be equipped with a sampling resistor, etc.

[0208] Step S110: When the current value of the impact mechanism is not less than the preset current value, start timing.

[0209] In step S110, after the power tool 100 is powered on, a small current is generated inside it. However, at this time, the motor 2 of the impact mechanism is not working properly. Therefore, a preset current value can be set, which represents the average current value or minimum current value of the motor 2 under normal working conditions. As an example, the preset current value can be 3A, 5A, 10A, etc.

[0210] When the current value of the impact mechanism is greater than or equal to the preset current value, it indicates that the motor 2 is indeed working normally. Therefore, when the current value of the impact mechanism is detected to be greater than or equal to the preset current value, a timer can be started. The usage time can then be obtained.

[0211] In another possible example, after step S200, the following is included:

[0212] Step S600: When the usage time is greater than or equal to the first preset time, the parameter value of the power tool 100 is determined to be a fixed value.

[0213] In step S600, as an example, when the usage time is greater than or equal to a first preset time, it can be considered that the power tool 100 has reached its usage limit, and the parameter values ​​of the power tool 100 have reached the limit that the structure can bear. Therefore, it is not necessary to calculate the parameter values ​​of the power tool 100 thereafter; preset fixed values ​​can be used. The fixed value can be the maximum value of the parameters that the power tool 100 can bear during the test.

[0214] As an example, the first preset duration can be 15s, 20s, 30s, etc. If the power tool 100 is an electric wrench, the fixed value can be 1500 N.m, 2000 N.m, 3000 N.m, etc. The above values ​​are for illustrative purposes only; in actual embodiments, the first preset duration and the fixed value are not limited to these values.

[0215] As mentioned above, the power tool 100 includes the display screen 6. Therefore, in one embodiment, after step S500, the following may be included:

[0216] Step S700: Control the display screen 6 to display the parameter values ​​of the power tool 100.

[0217] In step S700, as an example, the display circuit board of the display screen 6 is provided with a display screen 6 driving module, which is connected to the control device. After the control device obtains the parameter values ​​of the power tool 100, the parameter values ​​can be displayed on the display screen 6 through the display screen 6 driving module. As an example, the parameter value can be displayed at the torque value 66 on the display screen 6.

[0218] Furthermore, step S700 includes:

[0219] Step S710: When the usage time is within the first time interval, refresh the parameter values ​​of the power tool 100 displayed on the display screen 6 at first time intervals.

[0220] Step S720: When the usage duration is within the second time interval, refresh the parameter values ​​of the power tool 100 displayed on the display screen 6 at second time intervals, where the first time interval is shorter than the second time interval and the first time interval is shorter than the second time interval.

[0221] The inventors discovered that the parameter values ​​of the power tool 100 change drastically during the first time interval, while the parameter values ​​change gradually during the second time interval. Therefore, in steps S710 to S720, the display screen 6 can be set to have different refresh intervals according to different usage durations, thereby avoiding power waste.

[0222] As an example, the first time interval can be [0, 8000ms], and the second time interval can be [8000ms, ∞]. The first time interval can be 20ms, 50ms, etc. The second time interval can be 70ms, 100ms, etc. The above values ​​are for illustrative purposes only and do not limit the scope of protection of this embodiment.

[0223] In one embodiment, step S500 includes:

[0224] Step S510: Based on the time-parameter value function, determine the target data table, which includes the parameter values ​​of the power tool 100 corresponding to each usage duration under the time-parameter value function.

[0225] In step S510, each of the time-parameter value functions has a corresponding data table. For example, the data table stores the parameter values ​​of the power tool 100 for each usage duration. It can be understood that the parameter values ​​of the power tool 100 can be pre-calculated.

[0226] Step S520: Based on the usage duration, look up the parameter value of the power tool 100 in the target data table.

[0227] In step S520, the parameter values ​​of the power tool 100 corresponding to the usage duration can be found in the target data table.

[0228] In this embodiment, by pre-storing multiple usage durations and corresponding parameter values ​​of the power tool 100, the required parameter values ​​of the power tool 100 can be quickly found.

[0229] It is understood that this specification provides two different methods for determining the parameter values ​​of the power tool 100. The power tool 100 provided in this specification can either calculate the parameter values ​​of the power tool 100 in real time or look up the parameter values ​​of the power tool 100 in a pre-stored data table, thereby meeting the needs of different scenarios.
