Fig. 1 and Fig. 2 respectively show the general structure and assembly relationship of an embodiment of the removable power battery and electric tool according to the present application from the perspective of component parts. 3 and 4 respectively show schematic flowcharts of two embodiments of a method for transmitting data between an electric tool or a removable power battery and a communication terminal according to the present application. The technical solution of the present application will be described in detail below in conjunction with the above drawings.

First, refer to FIG. 1, which shows an embodiment of a removable power battery in a modular form. The removable power battery 100 can be used to provide power to the power tool 200 when it is connected to it. Specifically, the removable power battery 100 includes at least three parts: a battery main body 110, a wireless communication module 120, and a data storage module 140. Among them, the battery body 110 may be a general component for charging and discharging; the wireless communication module 120 is used to provide the possibility of data transmission; and the data storage module 140 stores an identification code for identifying the removable power battery And it can also be used to store the operating data of the removable power battery.

At this point, on the one hand, when the user or manufacturer desires to obtain the operating data of the power battery, it can identify the removable power battery for which the data is expected to be obtained through the identification code; subsequently, in the case of obtaining authorization, or directly omit the authorization After the steps, the user can upload and download the operating data of the removable power battery 100 through the communication terminal via the wireless communication module 120, so as to perform functions such as data storage, backup, analysis, error correction, or application in the communication terminal.

On the other hand, when the removable power battery 100 is connected to the power tool, the wireless communication module 120 can upload and download the power tool 200 between the power tool 200 and the communication terminal when authorization is obtained, or after the authorization step is directly omitted. The operation data of the communication terminal, so as to perform data storage, backup, analysis, error correction or application functions in the communication terminal.

According to the technical solution of the present application, by incorporating a wireless communication module into the removable power battery, on the one hand, it provides a hardware foundation for both the power battery itself and the Internet of Things application of power tools; on the other hand, products that require communication certification are Different electric tools become a single product with removable power batteries, which simplifies the process. In addition, by providing an identification code for the removable power battery or power tool, the upload or download of data can be accurately located to the desired removable power battery or power tool. Moreover, this type of removable power battery has better randomized usability, and it can also collect and integrate relevant data of any battery or any electric tool that uses the battery through the identification code, so as to meet all kinds of data Acquisition and analysis needs.

On the basis of the foregoing embodiments, several modifications can be made to the various parts of the removable power battery or the connection position relationship thereof, in order to obtain other or additional technical effects, which will be exemplified as follows.

For example, as a type of application mode, it can also provide rental services for the removable power battery. At this time, the problem of effectively preventing loss should also be solved. Therefore, a positioning module 130 can be additionally provided for the removable power battery to obtain the current position of the removable power battery 100, and the wireless communication module 120 further uploads the position data to the communication terminal. Thereby, it provides a foundation for preventing loss, or when it is determined to be lost, the corresponding removable power battery can be remotely controlled to power off to avoid illegal use.

For another example, the wireless communication module 120 can also be used to receive a control signal from a communication terminal, and the control signal can be used to activate the operation of the electric tool 200 and/or the removable power battery 100. As an example, when the maintenance party learns that the current machine is in a potentially damaged or abused state through the operating data uploaded to the communication terminal, it can send a control signal in reverse to trigger the start of the tool's warning light, or directly drive the tool to stop.

For another example, the battery body 110 has a standardized interface capable of randomized docking with different electric tools, so that it can be applied to different types of electric tools. This is extremely easy to achieve on a technical level, and even some current electric tools have used removable power batteries 100 with uniform specifications and interfaces. At this time, it is also an electric tool with data transmission function. At this time, only the communication certification for products such as removable power batteries is required, and the certification of various types of power tools is exempted, which greatly reduces product standardization. Complexity. In addition, since they are all standardized interfaces, users can choose whether to use such batteries with wireless communication modules according to their actual needs and cost considerations, which is more applicable. Furthermore, the user can also choose whether to configure an electric tool with an identification code, or still use an old-fashioned electric tool that has been produced or purchased. Due to the standardized interface, the power battery with or without the wireless communication module or the power tool with or without the identification code can be randomly connected, which also provides a stable application transition period between the new and the old products.

In addition, it should be understood that, in this application, the communication terminal that receives operation data from the wireless communication module or sends operation data to the wireless communication module may include a mobile communication terminal, a fixed communication terminal, a gateway, or the cloud. Among them, a mobile communication terminal or a fixed communication terminal may be a communication medium for a user or manufacturer to intervene in an electric tool, and it may be a mobile phone, a tablet computer, a notebook computer, a desktop computer, and the like. The cloud terminal is mainly the terminal for manufacturers to collect and analyze data from multiple electric tools. It should also be known that the wireless communication module 120 may include a Bluetooth module, a LoRa module, an NB-IoT module or an eMTC module, so as to be adapted to short-range wireless communication, long-range wireless communication, or to different regulations of various countries and regions.

In addition, optionally, the removable power battery can be directly used to supply power to the wireless communication module, thereby eliminating the need for a dedicated power supply for the wireless communication module installed in the power tool or other possible locations, further reducing costs And optimize the design. As another type of optional solution, a backup power supply can be additionally configured in the removable power battery to supply power to the wireless communication module, thereby avoiding the battery body of the removable power battery from exhausting the power supply for the power tool and causing no further satisfaction. The situation of IoT data transmission needs.

Referring to Fig. 2 again, the present application also provides an embodiment of an electric tool. It should be understood that the electric tools can be various types of electric tools that have been maturely applied or are being developed in the field, such as electric drills, cutting machines, or electric hammers; as long as they have the possibility of data collection requirements, they can be made. Corresponds to the configuration of the electric tool in this application.

Specifically, the electric tool includes a tool body 210 and a removable power battery 100. Among them, the tool main body 210 has an execution component 211 for executing a corresponding type of work and a control unit 212 for controlling the execution component. The control unit also has a data storage for storing the identification code used to identify the tool body 210 and the operating data of the execution component 211, so as to provide a hardware basis for its data collection and transmission. Since this kind of improvement is mainly concentrated on the control unit of the electric tool, there is almost no need to make changes to the tool body, which has excellent applicability. In addition, the removable power battery 100 has a battery main body 110 for charging and discharging, so as to provide power to the tool main body 210. The power battery can be configured with or without a wireless communication module as required to meet the needs of different users. Similarly, since the battery body does not need to be modified, the compatibility and applicability of the two are extremely strong. This kind of electric tool realizes the data collection and classification of the tool main body, so that the data conforming to the same identification code can be uploaded or downloaded when matched with the aforementioned removable power battery, so as to satisfy the subsequent possible data analysis and application. In addition, taking into account the needs of different user groups, it can also be combined with conventional removable power batteries to reduce the cost of power tools when users do not need the data collection function.

On the basis of the foregoing embodiment, several modifications can be made to the various parts of the electric tool or the connection position relationship thereof in order to obtain other or additional technical effects, which will be exemplified as follows.

For example, for a type of removable power battery used in the aforementioned electric tool, it also includes a wireless communication module 120 to upload and download the operating data of the execution component 211 between the control unit 212 of the tool main body 210 and the communication terminal. . When this type of removable power battery 100 is connected to an electric tool, the wireless communication module 120 can upload and download the operation of the tool body 210 between the tool body 210 and the communication terminal when authorization is obtained, or after the authorization step is directly omitted. Data in order to perform data storage, backup, analysis, error correction, or application functions at the communication terminal. In addition, the removable power battery can supply power to the wireless communication module at the same time, and it also eliminates the additional requirements for a dedicated power supply of the wireless communication module installed in the power tool or other possible locations, further reducing costs and optimizing the design.

For another example, the removable power battery 100 may further include a data storage module 140 that stores an identification code for identifying the removable power battery and is used to store operating data of the removable power battery 100. At this time, the wireless communication module 120 can also upload and download the operation data of the removable power battery 100 between the removable power battery 100 and the communication terminal. As a type of application mode of the foregoing embodiment, a rental service can also be provided for the removable power battery. At this time, the problem of effectively preventing loss should also be solved. For example, a positioning module 130 may be additionally provided for the removable power battery to obtain the current position of the removable power battery 100, and further the wireless communication module 120 uploads the position data of the removable power battery 100 to the communication terminal. This provides a basis for finding loss prevention, or when it is determined to be lost, the corresponding removable power battery is remotely controlled through the communication terminal to perform a forced power-off operation, thereby preventing the battery from being illegally used. For another example, the wireless communication module 120 can also be used to receive a control signal from a communication terminal, and the control signal can be used to activate the operation of the electric tool 200 and/or the removable power battery 100. As an example, when the maintenance party learns that the current machine is in a potentially damaged or abused state through the operating data uploaded to the communication terminal, it can send a control signal in reverse to trigger the start of the tool's warning light, or directly drive the tool to stop.

Similarly, it should be understood that the communication terminal and the applicable wireless communication module described here that communicate data with the wireless communication module are also applicable to the detailed explanations made in the foregoing.

In addition, in order to provide users with better services, the operating data collected and stored by the data memory collected by the control unit can be further clarified, which can be used to indicate the status data, usage data, and GPS positioning data of the power battery or electric tool , Remote control data, etc., but not limited to this. For example, it may include: the first type of operating data that feeds back the operating parameters of the execution component 211; and/or the second type of operating data that feeds back the user's operating habits, both of which are only classified for the foregoing purpose, and the data itself There may be a certain degree of overlap, which does not affect its application.

Specifically, the first type of operation data may include normal operation parameters of the execution component 211 and abnormal operation parameters of the execution component 211, so as to feed back the normal and abnormal operation status of the execution component 211. Wherein, as an example, the normal operating parameters of the execution component 211 may include: the execution component 211 running time and current or power or temperature statistical data, the control unit 212 running time, the execution component 211 switching frequency or times, the execution component 211 mode switching frequency or One or more of the number of times, the statistical data of the temperature of the battery body 110 or the temperature curve, in order to understand the use status of the executive components, and then determine whether maintenance needs to be done and what kind of maintenance needs to be done. On this basis, it can also be A maintenance reminder is issued to the user, so that the execution component 211 can work in a good state throughout its life cycle.

Several examples will be listed below to describe the possible applications of the above operating parameters. For example, in the initial stage of designing a power tool, the service life of its various parts and the overall tool should usually be considered. In terms of current, in the past, it may be necessary to design tools that can work normally within the current range of 0 to B for ten years as expected. After obtaining the current, duration, power, and temperature parameters of the actuator 211 of the electric tool under normal operation in batches, the design expectation value can be reduced to the current range from A to B, so as not to damage the performance of the tool. , Can optimize its service life, but also reduce its design requirements. For another example, by collecting and studying the switching frequency or frequency of the execution component 211, the mode switching frequency or frequency of the execution component 211, etc., the work efficiency of the worker operating the current tool can be effectively learned, and then the operational proficiency or operating attitude can be understood. For another example, for power batteries that are usually composed of lithium batteries, temperature has a greater impact on their working performance. At this time, by collecting and researching the temperature of the normal working environment of the corresponding power battery (which affects the battery's own temperature), it is possible to consider whether it is necessary to additionally configure a cooling module for the power battery in this area, so as to take into account the consideration of cost and efficiency.

As another example, the abnormal operation parameters of the execution component 211 may include one or more of the number of times the execution component 211 reports errors, the execution component 211 error record, the execution component 211 power-off record, and the execution component 211 power degradation record, so as to track the execution. The reason for the abnormality of the component is then determined whether maintenance, replacement or scrapping is required. On this basis, corresponding reminders can also be issued to the user, so that the execution component 211 can work in a good state throughout its life cycle.

In addition, the second type of operating data includes: the operating data of the user directly operating the execution component 211 and the operating data of the user transmitted to the control unit 212 of the tool main body 210 through the wireless communication module 120, so that it can directly capture the user's information on the tool. Long-term usage habits and record them, or you can set them yourself based on the needs of users. More specifically, the operation data of the user directly operating the execution component 211 may include: the application frequency or number of times or duration of each mode of the execution component 211, the number of rebound shutdowns and the number of drop shutdowns, and the application of the removable power battery 100 with the wireless communication module 120 One or more of frequency or type statistics.

Several examples will be listed below to describe the possible applications of the above operating parameters. For example, in order to prevent the execution component 211 from touching the hard objects (such as steel bars, etc.) in the building wall and causing a rebound and accidentally injure workers, the power tool is usually equipped with a rebound shutdown function. And by studying the number of triggers of the function, the worker's proficiency in this type of operation or the normal use of the tool can also be learned. Similarly, the research on the number of triggers of the drop stop function can also be used to learn the worker's proficiency in this type of operation or the normal use of the tool.

As another example, the operation data transmitted by the user to the control unit 212 of the tool main body 210 through the wireless communication module 120 may also include: the user’s interaction data, the user’s customization or preference setting record, and the user’s operation parameter setting record. one or more. Therefore, when a customer randomly obtains a new electric tool and any power battery, such configuration information can be automatically loaded to the new electric tool via the communication terminal, so as to conform to its application habits and improve its operating convenience. For example, if the customer usually expects that after operating the executive parts of the power tool and stopping, the delay of the lighting lamp is increased to keep the effect for 10 seconds (assuming it is usually 1 second), then when they use a new tool, they can get used to the configuration Will be automatically loaded into the new electric tool, which is more in line with its operating habits.

Continuing to refer to FIG. 3, an embodiment of a data transmission method is also provided here, which can be applied to any embodiment or combination of the aforementioned electric tool 200, so as to better perform the removable power between the electric tool and the communication terminal. The operation data transfer of the wireless communication module on the battery.

Subsequently, S120 is executed, and the tool main body 210 verifies the power battery, and after the verification is passed, the wireless communication module 120 of the removable power battery 100 is opened to the operation data transmission authority. Next, execute S130, and the wireless communication module 120 uploads and downloads the operation data of the execution component 211 between the control unit 212 of the tool main body 210 and the communication terminal in a controlled manner, wherein the operation data stored in the communication terminal uses the corresponding tool main body 210 Identification code identification. According to the data transmission method of the present application, on the one hand, the security of data transmission is ensured, and on the other hand, the transmitted data is classified by identification code, so that each tool body has its own set of corresponding operation data records, thereby The data history of all aspects can be consulted or analyzed to assist in making other judgments.

Of course, as another example, the wireless communication module 120 can also be used to receive a control signal from a communication terminal, and the control signal can be used to activate the operation of the electric tool 200 and/or the removable power battery 100. As an example, when the maintenance party learns that the current machine is in a potentially damaged or abused state through the operating data uploaded to the communication terminal, it can send a control signal in reverse to trigger the start of the tool's warning light, or directly drive the tool to stop.

Turning to FIG. 4, another embodiment of the data transmission method is also provided here, which can be applied to any embodiment or combination of the aforementioned removable power battery 100, so as to better perform the removable power battery power and communication Operational data transfer between terminals.

Subsequently, execute S220 to upload and download the operating data of the removable power battery 100 through the communication terminal via the wireless communication module 120, wherein the operating data stored in the communication terminal is identified by the identification code corresponding to the removable power battery 100. According to the data transmission method of this application, on the one hand, the security of data transmission is ensured; on the other hand, the transmitted data is classified by the identification code, so that each removable power battery has its own set of operation data records. , So you can consult or analyze its various aspects of data history to assist in making other judgments.
