DETAILED DESCRIPTION

[0022] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0023] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0024] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0025] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0026] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of the specific value, the tolerance caused by manufacturing, assembly, and use associated with the specific value, etc. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular) may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0028] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0029] In this application, the terms "controller," "processor," "central processing unit," "CPU," and "MCU" are used interchangeably. Where a unit "controller," "processor," "central processing unit," "CPU," or "MCU" is used to perform a particular function, unless otherwise specified, the function may be performed by a single unit or multiple units.

[0030] In this application, the terms "device", "module" or "unit" can be implemented in the form of hardware or software to achieve specific functions.

[0031] In this application, the terms "calculate", "judge", "control", "determine", "identify", etc. refer to the operations and processes of a computer system or similar electronic computing device (e.g., controller, processor, etc.).

[0032] The present application discloses a power tool anti-theft system, wherein the power tool can be a handheld power tool, such as a drill, pruner, or sander. Alternatively, the power tool can be a benchtop tool, such as a table saw or miter saw. Alternatively, the power tool can be a push power tool, such as a push lawn mower or a push snow blower. Alternatively, the power tool can be a ride-on power tool, such as a ride-on lawn mower, a ride-on vehicle, or an all-terrain vehicle. Alternatively, the power tool can be a robotic tool, such as a robotic lawn mower or a robotic snow blower. In some embodiments, the power tool can be an electric drill, an electric light, or an electric vehicle. In some embodiments, the power tool can be a gardening tool, such as a pruner, a blower, a lawn mower, or a chainsaw. Alternatively, the power tool can be a decorating tool, such as a screwdriver, a nail gun, a circular saw, or a sander. In some embodiments, the power tool can be a vegetation care tool, such as a lawn mower, a lawn mower, a pruner, or a chainsaw. Alternatively, the power tool can be a cleaning tool, such as a blower, a snow blower, or a washer. Alternatively, the power tool may be a drilling tool, such as a drill, screwdriver, wrench, or electric hammer.

Alternatively, the power tool may be a bench tool, such as a table saw, miter saw, metal cutter, or router. Alternatively, the power tool may be a grinding tool, such as an angle grinder or sander. Alternatively, the power tool may be another tool, such as a lamp or fan.

[0033] See also Figure 1a and Figure 1b As shown, the power tool anti-theft system includes: a power tool body 100 and an enabling device 200. In this embodiment, the enabling device 200 can be coupled to the power tool body 100. The so-called coupling can be understood as being close enough to perform wireless communication, or being able to perform wired communication after being connected. In one embodiment, the enabling device 200 and the power tool body 100 are pluggable and connected, and the enabling device 200 is used to send activation information when the enabling device 200 and the power tool body 100 are in a connected state; the power tool body 100 includes at least: a controller 110, an activation component 120 and a warning component 130; the controller 110 is used to read the activation information to adjust the activation state of the activation component 120, and to control the warning component 130 to send or stop sending warning information according to the activation state.

[0034] In the present application, the power tool body 100 is configured with a working component. Different power tool types have different corresponding working components. For example, the working component may include, but is not limited to: a motor, a power transmission component (e.g., a gearbox, a drive wheel light), or a light-emitting component such as a lamp bead, a light strip, or a laser component.

[0035] In some embodiments, the warning component 130 includes at least one of the following: a buzzer, an indicator light, or a display device. In the present application, the controller 110 is configured to control the working component to operate in an abnormal operating mode when the activation component 120 is in an inactive state. In one embodiment, while controlling the working component to operate in the abnormal operating mode, the controller 110 can also control the warning component 130 to issue a warning message to alert the user that the power tool, while capable of starting or operating, is not yet activated. For example, the controller 110 can control the buzzer to emit a regular or irregular alarm sound, and / or control the indicator light to illuminate regularly or irregularly, and / or control the display device to display a warning message using text or images. In one embodiment, when the activation component 120 is in an active state, the controller 110 can control the working component to operate in a normal operating mode and control the warning component 130 to stop issuing the warning message. In this embodiment, the operating parameters of the working component in the abnormal operating mode differ from those in the normal operating mode. For example, the speed, torque, or operating power of the motor in the abnormal operating mode is lower than that in the abnormal operating mode. In some cases, the speed of the motor in the abnormal operating mode may be zero, or the motor may be powered on but not yet started to run in the inactive state.

[0036] In some embodiments, the abnormal operating mode may also include the warning component operating in the warning state, and the operating parameters of the motor are less than the operating parameters in the normal operating mode. That is, although the motor can be started or powered on, it cannot work normally and the user needs to perform activation operations.

[0037] In some embodiments, the abnormal operating mode may also include the warning component operating in a warning state, and the operating parameters of the motor are the operating parameters under the normal operating mode. That is to say, although the motor can work normally, the warning component is also warning the user that the current tool has not been activated and needs to be activated.

[0038] Or in some embodiments, the abnormal working mode may include the warning component working in a warning state, the working parameters of the motor are the working parameters in the normal working mode, and the warning state at least warns the maximum working time of the current motor under the normal working parameters. After the working time of the power tool reaches the maximum time, it can stop working and stop warning. For example, when the tool is not activated, the user is prompted to allow the tool to work normally for up to 10 minutes, and the warning component is continuously or periodically used to warn the user that the power tool needs to be activated during the operation of the tool. In other embodiments, the working method under the abnormal working mode may also include any other work that can be distinguished from the normal working mode, which will not be listed here one by one.

[0039] In some embodiments, some working components can also be reused as warning components. For example, a motor can be controlled to emit a special warning sound, or a power indicator light, a lighting lamp, or a display screen showing the working status of the power tool can be controlled to emit a special warning message. It is understood that reusing working components as warning components can avoid adding new components, which helps to save the production cost of the power tool.

[0040] In some embodiments, the enabling device 200 can be integrated into the adapter of the power tool and connect to the battery pack mounting portion of the power tool body 100. When the enabling device 200 and the power tool body 100 are connected, the enabling device 200 sends an activation message to the power tool body 100.

[0041] In other embodiments, the enabling device 200 may be configured as a standalone plug-in.

[0042] In the present application, the activation information of the enabling device 200 may be a character string carrying identity information, encryption information, etc. The activation information may be scanned by the merchant or stored in the enabling device 200 when the power tool is sold.

[0043] In some embodiments, the activation component 120 is in a permanently activated state after being activated. Specifically, when the user first purchases the power tool, the enabling device 200 is connected to obtain activation information. The activation component 120 is activated after receiving the activation information. Each subsequent use does not require reconnection to the enabling device 200. The controller 110 only needs to detect whether the activation component 120 is in an activated state. If the activation component 120 is in an inactivated state, the controller 110 controls the warning component 130 to issue a warning message. At this time, the power tool is not disabled. If the activation component 120 is in an activated state, the controller 110 controls the warning component 130 to stop issuing warning messages and can start normal operation control of the working component. By configuring the activation component and the warning component, a warning message is issued without disabling the power tool when the unlocking information is not received, thereby solving the problem that the existing power tool cannot work without being unlocked, and improving the user experience while achieving safety supervision of the power tool.

[0044] In some embodiments, the controller 110 is configured to control the working components to operate in the same operating mode, such as outputting the same power or speed, when the activation component 120 is in an inactive state or an active state. The power tool of the present application can also operate normally when it is inactive, which is conducive to improving the user experience.

[0045] In other embodiments, the controller 110 is configured to control the working component to operate in a low-power or low-speed mode when the activation component 120 is in an inactive state, and to control the working component to operate in a high-power or high-speed mode when the activation component 120 is in an active state. The power tool of the present application operates in different modes in an inactive state or an active state, ensuring that the power tool can operate normally even when not activated, while improving the compatibility of the power tool in different scenarios and enhancing the user experience.

[0046] In some embodiments, see Figure 2 As shown, the power tool body 100 also includes: a motor 140; an activation component 120 including a photosensor 121; and a controller 110 for changing the position of the motor 140 based on the activation information to turn the photosensor 121 on or off. The photosensor 121 is used to drive the warning component 130 to issue or stop issuing warning information. For example, taking the case where the warning component 130 issues a warning message when the photosensor 121 is on, when the activation component 120 does not receive the activation information, the controller 110 does not control the movement of the motor 140, the photosensor 121 is on, and the warning component 130 is driven to issue a warning message; when the activation component 120 receives the activation information, the controller 110 controls the motor 140 to move to a position that blocks the photosensor 121, the photosensor 121 is turned off, and the warning component 130 is driven to stop issuing a warning message.

[0047] In other embodiments, see Figure 3 As shown, the activation component 120 includes a fuse 122 and a blown branch 123. The controller 110 is used to control the blown branch 123 to be turned on or off based on the activation information, so that the fuse 122 is blown when the blown branch 123 is turned on. The fuse 122 is used to drive the warning component 130 to issue or stop issuing a warning message. For example, taking the warning component 130 issuing a warning message when the fuse 122 is not blown as an example, when the activation component 120 does not receive the activation information, the controller 110 controls the blown branch 123 to be turned off, the fuse 122 is not blown, and the warning component 130 is driven to issue a warning message; when the activation component 120 receives the activation information, the controller 110 controls the blown branch 123 to be turned on, the fuse 122 is blown, and the warning component 130 is driven to stop issuing a warning message.

[0048] In some embodiments, see Figure 4As shown, the enabling device 200 includes a memory 201, which is used to store at least activation information. In this embodiment, the memory 201 may be an EPROM memory. After the user purchases the power tool, the merchant uses a software program and / or hardware device (such as an operating member) to store the activation information in the memory 201 in the enabling device 200. When the enabling device 200 is connected to the power tool body 100, the enabling device 200 can send the activation information to the controller 110 of the power tool body 100. After receiving the activation information, the controller 110 changes the state of the activation component 120. In this application, the activation component 120 is in a permanently activated state after being activated.

[0049] In other embodiments, see Figure 5 As shown, the enabling device 200 also includes a communication unit 202, which is communicatively connected to an external terminal device. The communication unit 202 is configured to receive activation information from the terminal device and transmit the activation information to the controller 110. The controller 110 is configured to activate the activation component 120 based on the activation information. In this application, the communication unit 202 can utilize any of the following communication methods: radio frequency identification (RFID) or Bluetooth communication. For example, assuming that the communication unit 202 is equipped with an RFID chip, after a user purchases a power tool, the merchant uses a machine to scan the enabling device 200, transmitting activation information to the RFID chip in the enabling device 200. When the enabling device 200 is connected to the power tool body 100, the activation information can be transmitted to the controller 110 of the power tool body 100. Upon receiving the activation information, the controller 110 changes the state of the activation component 120. In this application, the activation component 120 is permanently activated after being activated. In one embodiment, the communication unit 202 may be provided in the power tool, or the communication unit 202 may be integrated into the controller 110 .

[0050] The present application discloses an electric tool that, after a user purchases the tool, loads a working program based on user operation. When the working program is not loaded, the electric tool does not work, thereby achieving anti-theft protection. Specifically, the electric tool can be a powered tool or a non-powered tool having a motor.

[0051] See also Figure 6As shown, the power tool 600 of the present application includes: a tool body 601; a working component 602 disposed on the tool body 601; a controller 110 configured to at least execute a working program to control the operation of the working component 602; the controller 110 includes: a communication device 111 configured to download the working program from an external network upon detecting unlocking information (e.g., an unlocking code containing identity information, encryption information, etc.); and a second memory 112 configured to store the working program. In this application, the working component 602 varies depending on the type of power tool 600. Typically, the working component 602 may include, but is not limited to, a motor, a power transmission component (e.g., a gearbox, a drive wheel light), or a light-emitting component such as a lamp bead, a light strip, or a laser element.

[0052] In the present application, the tool body 601 includes a shell and structural parts for supporting all functional modules of the power tool 600 .

[0053] In some embodiments, the second memory 112 may be an EPROM memory.

[0054] In some embodiments, the communication device 111 is configured to use wireless communication to obtain unlocking information sent by an external terminal. In this application, the external terminal may be a smart mobile terminal such as a laptop, smartphone, or wearable device. The wireless communication method includes any of the following: radio frequency identification (RFID) or Bluetooth communication. Specifically, after a user purchases the power tool 600, a set of unlocking information (e.g., a set of unlocking codes) is obtained. The user or merchant launches a specific application based on the external terminal and enters the obtained unlocking information. The controller 110 receives the unlocking information via the communication device 111 and, after detecting the unlocking information, downloads and stores the operating program from the external network. In this embodiment, the user can activate communication by operating an operating element on the power tool, such as a communication key. Once communication is activated, communication pairing with the external device can be performed. After successful pairing, the user can obtain the unlocking information entered through the external device and download the operating program from the external network after unlocking.

[0055] In some embodiments, see Figure 7As shown, the power tool 600 also includes an operating element 603; the operating element 603 is capable of responding to at least a first operating mode and generating operating instructions for controlling the operation of the operating component. The operating element 603 is also capable of responding to a second operating mode and generating unlocking information. The operating instructions and unlocking information may be stored in the second memory 112. In the present application, the operating element 603 may be one or more mechanical or touch-sensitive buttons, such as a speed control button or a power button on the power tool 600, which are originally adapted to control the normal operation of the power tool 600. The first and second operating modes can be distinguished by trigger duration, trigger count, etc. For example, the first operating mode may be a single trigger, while the second operating mode may be multiple triggers or a long press. For example, after purchasing the power tool 600, a user obtains an unlock code (e.g., 10110), where 1 indicates a button is pressed, 0 indicates a button is not pressed, and each button press is separated by a specific time interval. During initial startup, the user enters an unlock code based on the second operating mode. Operating element 603 generates unlock information in response to the second operating mode. Controller 110 receives this unlock information via communication device 111 and, upon detecting the unlock information, downloads and stores the operating program from the external network. After unlocking the power tool 600, the user can operate operating element 603 in the first operating mode to control normal operation of the power tool 600, including controlling the motor's rotation, stopping it, or changing its rotational state. By reusing operating elements, users can enter unlock codes and operating instructions using different operating rules, eliminating the need for a new password input interface or plug-in.

[0056] In some embodiments, see Figure 8 As shown, the power tool 600 further includes an activation component 120 and an alarm component 130. The activation component 120 is configured to control the alarm component 130 to issue an alarm message when the unlock message is not received, and to control the alarm component 130 to stop issuing the alarm message when the unlock message is received. In this application, the alarm component 130 includes at least one of the following: a buzzer, an indicator light, or a display device. By configuring the activation component 120 and the alarm component 130, a power tool safety alarm is implemented, enhancing the user experience.

[0057] This application also discloses another electric tool, which is unlocked based on user operation after the user purchases the tool, and the electric tool can work normally after unlocking. Figure 9 As shown, the electric tool 600 of the present application includes: a tool body 601; a working component 602, which is arranged on the tool body 601; an operating member 603, which is configured to at least respond to a first operating mode to generate a working instruction to control the operation of the working component 602; a controller 110, which is at least connected to the working component 602; the operating member 603 can respond to a second operating mode and generate unlocking information; the controller 110 is configured to respond to the unlocking information to control the operation of the working component 602.

[0058] In this embodiment, the operating element 603 is multiplexed to be able to respond to at least two operating modes, responding to the first operating mode to generate a working instruction to control the operation of the working component, and responding to the second operating mode and generating unlocking information.

[0059] In the present application, the operating element 603 may be one or more mechanical buttons or touch buttons. The first operating mode and the second operating mode may be distinguished by trigger duration, trigger number, etc. For example, the first operating mode may be a single trigger, and the second operating mode may be multiple triggers or a long press. For example, after the user purchases the power tool 600, a set of unlock codes (for example, 10110) is obtained, where 1 indicates that the button is pressed, 0 indicates that the button is not pressed, and each button press is separated by a specific time. At the first startup, it is used to input the unlock code based on the second operating mode. The operating element 603 generates unlock information in response to the second operating mode. The controller 110 receives the set of unlock information through the communication device 111. After detecting the unlock information, it downloads and stores the work program from the external network. By reusing the operating element, the user can input the unlock code and work instructions through different operating rules without the need for a new password input interface or plug-in.

[0060] In some embodiments, see Figure 10 As shown, the power tool 600 of the present application further includes an activation component 120 and an alarm component 130. The activation component 120 is configured to control the alarm component 130 to issue an alarm message when the unlock message is not received, and to control the alarm component 130 to stop issuing the alarm message when the unlock message is received. In the present application, the alarm component 130 includes at least one of the following: a buzzer, an indicator light, or a display device. By configuring the activation component 120 and the alarm component 130, a power tool safety alarm is implemented, enhancing the user experience.

[0061] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of this application.
