Description

TECHNICAL FIELD

[0001] The present application relates to the field of manual holding devices, in particular to a wrench. BACKGROUND

[0002] A wrench is a commonly used installation and disassembly tool, which is a hand tool for turning a bolt, screw, nut or other threaded fastener by using the principle of a lever. Among them, the torque wrench is widely used in industry, civil and other occasions requiring torque tightness.

[0003] When workers use it, they will put various hand tools in a tool bag, which are mixed together, and it is difficult to find in an emergency. In addition, due to the applicability of the wrench, workers will also borrow wrenches from each other, so it is more difficult to track the location of the wrench.

[0004] Therefore, a wrench with positioning function appears on the market, which is provided with a positioning chip and a wireless transmission device powered by a wrench battery. The positioning chip is used for positioning, and the wireless transmission device is used to inform the manager of the location of the wrench. However, in actual application, if the wrench battery is overpowered and the battery is zero, or the wrench battery is taken out and cannot power the positioning chip, the positioning function of the wrench cannot be realized, and the manager also cannot locate the position of the wrench. SUMMARY

[0005] In order to continuously and effectively position the wrench, the present application provides a wrench.

[0006] The present application provides a wrench, which adopts the following technical solutions:

[0007] A wrench is provided with a positioning assembly and a power supply control circuit, the power supply control circuit includes a photovoltaic assembly and a communication assembly;

[0008] The photovoltaic assembly is electrically connected with the communication assembly and the positioning assembly respectively, so as to convert solar energy into electric energy and supply power to the communication assembly and the positioning assembly;

[0009] The positioning assembly is electrically connected with the communication assembly, and is used for periodically transmitting the position information of the wrench to the communication assembly;

[0010] The communication assembly is used for wireless connection with an external terminal, so as to transfer the position information to the external terminal.

[0011] In the technical solution, the photovoltaic assembly converts solar energy into electric energy to supply power to the positioning assembly and the communication assembly, so that the positioning assembly and the communication assembly can work normally in an emergency, the operation of the positioning assembly is stable, and the positioning assembly cannot work normally due to insufficient energy of the energy storage element and cannot feed back the position of the wrench to the user. Compared with the prior art in which the energy storage element supplies power to the positioning assembly and the communication assembly, even if the energy storage element itself is insufficient in electric quantity, the positioning assembly and the communication assembly can still work.

[0012] When the user uses the wrench, the user only needs to go to a place with light, so that the positioning assembly and the communication assembly can work normally. The positioning assembly periodically transmits the position information of the wrench to the communication assembly, and the communication assembly transmits the position information to the external terminal, so that the worker managing the wrench can know the position of the corresponding wrench, thereby improving the management of the wrench. Similarly, the user can also know the position of the wrench needed by the user through the external terminal, so that the user can quickly take the wrench.

[0013] Optionally, the wrench is provided with a monitoring assembly, the wrench has a cavity for accommodating an energy storage element, the energy storage element is used to be electrically connected with the monitoring assembly to supply power to the monitoring assembly, and the power supply control circuit further comprises a master control assembly, the master control assembly has a power supply port, an energy storage monitoring port and a signal output port, the power supply port is electrically connected with the photovoltaic assembly and is used to receive electric energy from the photovoltaic assembly, the energy storage monitoring port is used to be electrically connected with the energy storage element to periodically detect the residual electric quantity of the energy storage element, and the signal output port is electrically connected with the communication assembly.

[0014] In the working state, the master control assembly generates an alarm signal when the residual electric quantity is lower than a preset alarm threshold and transmits the alarm signal to the communication assembly, and the communication assembly is further used to transmit the alarm signal to the external terminal.

[0015] In the technical solution, the master control assembly periodically monitors the residual electric quantity of the energy storage element through the energy storage monitoring port, and generates an alarm signal through the communication assembly when the residual electric quantity is lower than a preset alarm threshold, so as to prompt the user to replace the energy storage element or charge the energy storage element in time. Moreover, the master control assembly and the communication circuit are both supplied with power by the photovoltaic assembly, and can still work normally when the energy storage element is insufficient in electric quantity. In the case that the photovoltaic assembly works normally, the master control assembly can monitor the energy storage element with any electric quantity, thereby ensuring the stability of the execution of the scheme.

[0016] Optionally, the monitoring assembly further comprises a torque sensor, and the master control assembly further has a signal input port electrically connected with the torque sensor to receive a torque signal fed back by the torque sensor, and in the working state, the master control assembly transmits the received torque signal to the communication assembly, and the communication assembly is further configured to forward the received torque signal to the external terminal.

[0017] In the technical solution, the torque sensor works under the power supply of the energy storage member, and the torque sensor feeds back a torque signal when a user holds the wrench to turn the target fastener, the monitoring assembly receives the torque signal and transmits the torque signal to the communication assembly for forwarding to the external terminal. Therefore, a workpiece manager using the external terminal can know the actual use of the wrench, and thus supervise whether the user as an operator correctly uses the corresponding wrench.

[0018] Optionally, the power supply control circuit further comprises a charging switch, the charging switch has a first end and a second end, the first end is electrically connected with the energy storage member, and the second end is electrically connected with the photovoltaic assembly, wherein, in the case that the charging switch is turned on, the photovoltaic assembly charges the energy storage member, and in the case that the charging switch is turned off, the photovoltaic assembly stops charging the energy storage member.

[0019] In the technical solution, the two ends of the charging switch are connected with the photovoltaic assembly and the energy storage member respectively, and in actual application, a user can control the on-off of the charging switch according to needs, so that the photovoltaic assembly converts light energy into electric energy and then delivers the electric energy to the energy storage member for charging, so as to realize emergency charging when the energy storage member is insufficient.

[0020] Optionally, the master control assembly further has a charging control port, and the power supply control circuit further comprises a charging switch, the charging switch has a first end, a second end and a third end, the first end is electrically connected with the energy storage member, the second end is electrically connected with the photovoltaic assembly, and the third end is electrically connected with the charging control port.

[0021] In the working state, when the remaining electric quantity is lower than a preset charging threshold, the master control assembly controls the first end and the second end to be turned on, so that the photovoltaic assembly charges the energy storage member, and when the remaining electric quantity is not lower than the preset charging threshold, the master control assembly controls the first end and the second end to be turned off, so that the photovoltaic assembly stops charging the energy storage member.

[0022] By adopting the technical scheme, the main control assembly controls the first end and the second end of the charging switch to be connected or disconnected according to the residual power of the energy storage device detected by the energy storage monitoring port, so that the charging switch sends a signal to the third end of the charging switch, thereby interrupting the charging of the energy storage device by the photovoltaic assembly when the energy storage device has sufficient energy, avoiding overloading of the energy storage device, and automatically controlling the charging of the energy storage device by the photovoltaic assembly when the energy storage device has insufficient energy, thereby ensuring the energy storage of the energy storage device.

[0023] Optionally, the power supply control circuit further comprises a power supply switch; the power supply switch has a first end and a second end, the first end is electrically connected with the energy storage device, and the second end is electrically connected with the monitoring assembly, wherein, in the case that the power supply switch is connected, the energy storage device supplies power to the monitoring assembly, and in the case that the power supply switch is disconnected, the energy storage device stops supplying power to the monitoring assembly.

[0024] By adopting the technical scheme, the two ends of the power supply switch are connected with the monitoring assembly and the energy storage device respectively, and a user can control whether the energy storage device supplies power to the monitoring assembly by adjusting the connection and disconnection of the power supply switch.

[0025] Optionally, the main control assembly further has a power supply control port, and the power supply control circuit further comprises a power supply switch, the power supply switch has a first end, a second end and a third end, the first end is electrically connected with the energy storage device, the second end is electrically connected with the electronic component, and the third end is electrically connected with the power supply control port.

[0026] In the working state, the main control assembly controls the power supply switch to be connected when the torque signal indicates that the wrench is in the stressed state, so that the energy storage device supplies power to the monitoring assembly, and controls the power supply switch to be disconnected when the time period during which the torque signal indicates that the wrench is in the non-stressed state reaches the preset shutdown trigger time length, so that the energy storage device stops supplying power to the monitoring assembly.

[0027] By adopting the technical scheme, the main control assembly controls the power supply switch to be connected according to the stressed state of the wrench indicated by the torque signal, and the energy storage device supplies power to the monitoring assembly, so as to ensure the normal work of the monitoring assembly. The main control assembly controls the power supply switch to be disconnected according to the time period during which the non-stressed state of the wrench indicated by the torque signal reaches the shutdown trigger time length, and the energy storage device stops supplying power to the monitoring assembly, so as to realize the automatic stop of power supply of the wrench in the non-stressed state after the shutdown trigger time length is reached, that is, the automatic shutdown. According to the time period during which the wrench is in the non-stressed state, the monitoring assembly is automatically shut down, which is obviously more energy-saving for the energy storage device supplying power to the monitoring assembly all the time.

[0028] Optionally, the monitoring assembly further comprises a human-computer interaction assembly, which is electrically connected with the master control assembly; in the working state, the human-computer interaction assembly is configured to display the current working parameter to the user and receive the control instruction from the user, and transmit the control instruction to the master control assembly.

[0029] In the working state, the master control assembly is further configured to perform the corresponding control operation according to the control instruction, and transmit the current working parameter to the communication assembly according to the preset period, so as to trigger the communication assembly to forward the current working parameter to the external terminal.

[0030] Through the above technical solution, the human-computer interaction assembly displays the current working parameter, so that the user can fully understand the working state of the wrench. At the same time, the human-computer interaction assembly can also facilitate the user to input the control instruction to the master control assembly and perform the corresponding operation, realizing the manual control of the wrench. At the same time, the master control assembly receives the control instruction and performs the operation, and also periodically sends the current working parameter to the external terminal, so that the remote workpiece management personnel can understand the operation of the wrench by the user, and more conveniently monitor whether the user uses the wrench in accordance with the regulations.

[0031] Further, the working parameter comprises a torque value indicated by the torque signal, and when the torque signal indicates that the wrench is in a non-stressed state for a preset hibernation trigger duration, the master control assembly interrupts the power supply of the energy storage member to the human-computer interaction assembly.

[0032] Through the above technical solution, the master control assembly controls the power supply of the energy storage member to the human-computer interaction assembly according to the stressed state of the wrench indicated by the torque signal. The master control assembly controls whether the power supply of the energy storage member to the human-computer interaction assembly is interrupted or continued according to whether the duration of the wrench in the non-stressed state reaches the hibernation trigger duration. Compared with the above-mentioned power supply of the energy storage member to the torque sensor and the human-computer interaction assembly throughout the process, the present application realizes the automatic hibernation and automatic shutdown of the wrench, saves the energy of the energy storage member as much as possible, and avoids energy waste.

[0033] Optionally, the power supply control circuit further comprises a preprocessing circuit comprising an amplifier, the preprocessing circuit having a first end and a second end, the first end being configured to be electrically connected with the torque sensor to receive the raw-state torque signal fed back by the torque sensor, and the second end being electrically connected with the signal receiving port of the master control assembly to output the preprocessed torque signal.

[0034] By adopting the technical scheme, the pretreatment circuit amplifies the torsion signal output by the torsion sensor, and then transmits the amplified torsion signal as a pretreated torsion signal to the master control component. Compared with directly transmitting the torsion signal to the master control component, the amplified torsion signal can carry more information, so that the master control component can more accurately and reliably monitor the state of the torsion sensor.

[0035] Optionally, the wrench comprises a connecting portion, a main body portion and a force receiving portion.

[0036] The connecting portion is fixedly connected with one end of the main body portion and is used for being embedded with a target fastener, and the force receiving portion is fixedly connected with the other end of the main body portion and is used for receiving a torsion applied by a user, and the positioning component, the monitoring component and the power supply control circuit are arranged on the main body portion.

[0037] The cavity is located in the force receiving portion or in the main body portion or partially in the force receiving portion and partially in the main body portion.

[0038] In the above scheme, in actual use, the connecting portion is embedded with the target fastener, then the user holds the force receiving portion of the wrench to apply the torsion, the monitoring component arranged on the main body portion senses the force receiving condition of the wrench to generate a torsion signal, and the monitoring component transmits the torsion signal to the power supply control circuit, so that the power supply control circuit adjusts the power supply state of the energy storage component to the monitoring component according to the force receiving condition of the wrench indicated by the torsion signal. In addition, the master control component in the power supply control circuit also monitors the residual power of the energy storage component to timely inform the external terminal in communication connection with the master control component through the communication circuit, so as to prompt the energy storage component to be insufficient in power supply, and facilitate the user to replace the energy storage component or charge the energy storage component in time.

[0039] In summary, the present application has at least one of the following beneficial technical effects:

[0040] 1. The positioning component and the communication component are independently powered by the photovoltaic component, so that even if the energy storage component has zero power or is removed, the positioning component and the communication component can still work and transfer the position information of the wrench to the external terminal through the communication component, thereby facilitating the workpiece management personnel or the user to find the position of the wrench.

[0041] 2. The master control component and the communication component are powered by the photovoltaic component, so that the master control component and the communication component can still work when the energy storage component has insufficient power or zero power, and the master control component can still monitor the residual power of the energy storage component and transfer the alarm signal representing that the residual power is lower than the preset alarm threshold to the external terminal through the communication component.

[0042] 3. In normal operation, the main control component can receive the torque signal fed back by the torque sensor in the monitoring component, and adjust the power supply state of the energy storage component to the monitoring component according to the force condition of the wrench indicated by the torque signal, so as to realize the switching of the working state of the wrench, i.e., the working state, the sleep state and the shutdown state; specifically, when the time indicated by the torque signal that the wrench is in the non-force state reaches the sleep trigger duration, the sleep state is switched, and the power supply of the energy storage component to the human-computer interaction component is interrupted, when the time indicated by the torque signal that the wrench is in the non-force state reaches the shutdown trigger duration, the shutdown state is switched, and the power supply of the energy storage component to the monitoring component including the human-computer interaction component and the torque sensor is interrupted, and when the torque signal indicates that the wrench is in the force state, the energy storage component supplies power to the monitoring component.

[0043] The working state switching of the wrench can reduce the irrelevant energy consumption of the energy storage component as much as possible. When the wrench is in the non-force state, i.e., the wrench is not currently used, the wrench enters the sleep state after the idle sleep trigger duration, and the power supply to the human-computer interaction component is interrupted. However, when the wrench is used again in the sleep state, the power supply to the human-computer interaction component is restored, and the use of the overall function of the wrench is not affected. When the wrench is idle for the shutdown trigger duration, the wrench enters the shutdown state, the power supply to the human-computer interaction component and the torque sensor is interrupted, and the automatic shutdown is realized, thereby saving the electric energy of the energy storage component.

[0044] 4. In normal operation, the main control component can receive the torque information sent by the torque sensor, and then send the received torque information to the communication circuit for forwarding to the external terminal in communication connection with the communication circuit, so as to realize the monitoring of the working state of the wrench by the user.

[0057] First Embodiment:

[0058] As shown in the drawings, the first embodiment of the present application discloses a wrench 100, which is provided with a positioning assembly 20 and a power supply control circuit 10, the power supply control circuit 10 comprising a photovoltaic assembly 11 and a communication assembly 13; Figure 1

[0059] ​The photovoltaic assembly 11 is electrically connected with the communication assembly 13 and the positioning assembly 20 respectively to convert solar energy into electric energy and supply power to the communication assembly 13 and the positioning assembly 20.

[0060] The positioning assembly 20 is electrically connected with the communication assembly 13 to periodically transmit the position information of the wrench 100 to the communication assembly 13.

[0061] The communication assembly 13 is configured to be wirelessly connected with an external terminal 200 to transfer the position information to the external terminal 200.

[0062] In the technical scheme, the photovoltaic assembly 11 converts solar energy into electric energy to supply power to the positioning assembly 20 and the communication assembly 13, so that the positioning assembly 20 and the communication assembly 13 can normally work in an emergency, and the operation of the positioning assembly 20 is stable.

[0063] When the user uses the wrench, the user only needs to go to a place with light, so that the positioning assembly 20 and the communication assembly 13 can normally work, and then the positioning assembly 20 periodically transmits the position information of the wrench to the communication assembly 13 to be transferred to the external terminal 200, so that a worker managing the wrench can know the position of the wrench, and the management of the wrench is strengthened. Similarly, the user can also know the position of the wrench needed by the user through the external terminal, so that the user can more quickly take the wrench.

[0064] In some examples, as shown in Figure 1 The wrench is provided with a monitoring assembly 30, the wrench has a cavity for accommodating an energy storage piece 40, the energy storage piece 40 is electrically connected with the monitoring assembly 30 to supply power to the monitoring assembly 30, and the power supply control circuit 10 further includes a master control assembly 12, the master control assembly 12 has a power supply port, an energy storage monitoring port and a signal output port, the power supply port is electrically connected with the photovoltaic assembly 11 to receive electric energy from the photovoltaic assembly 11, the energy storage monitoring port is electrically connected with the energy storage piece 40 to periodically detect the remaining electric quantity of the energy storage piece 40, and the signal output port is electrically connected with the communication assembly 13.

[0065] In the working state, the master control assembly 12 generates an alarm signal when the remaining electric quantity is lower than a preset alarm threshold and transmits the alarm signal to the communication assembly 13, and the communication assembly is further configured to transfer the alarm signal to the external terminal 200.

[0066] In the example, the master component 12 periodically monitors the remaining power of the energy storage 40 through the energy storage monitoring port, and when the remaining power is lower than the preset warning threshold, the communication component 13 is used to send a warning to prompt the user that the energy storage 40 is running out of power, so that the user can replace the energy storage 40 or charge the energy storage 40 in time. Moreover, the master component 12 and the communication circuit are both powered by the photovoltaic component 11, and can still work normally when the energy storage 40 is running out of power. In the case that the photovoltaic component 11 works normally, the master component 12 can monitor the energy storage 40 with any power, ensuring the stability of the scheme execution.

[0067] Specifically, the photovoltaic component 11 is built-in with photovoltaic cells and conversion circuits. The photovoltaic component 11 absorbs solar energy on the surface, converts the absorbed solar energy into electric energy through the conversion circuit, and then delivers the electric energy to the photovoltaic cells. The photovoltaic cells are electrically connected with the master component 12 and the communication component 13 to supply power to the master component 12 and the communication component 13.

[0068] Specifically, the communication component 13 uses at least one of a data line, a Bluetooth module, and a WiFi communication module to establish a communication connection with the external terminal 200, so as to send the received information to the external terminal 200 through the communication connection, and realize remote reminding, warning, monitoring and other functions. The communication connection established by the data line can also be replaced by other wired communication methods. The Bluetooth communication connection established by the Bluetooth module and the wireless network communication connection established by the WiFi communication module can also be replaced by other wireless network communication methods.

[0069] Specifically, the energy storage 40 can use ordinary disposable batteries or rechargeable batteries, and is designed to supply power to the monitoring component 30. When the energy storage 40 uses disposable batteries, the user can replace the disposable batteries in time to ensure the normal use of the monitoring component 30 in the subsequent period when the user knows the warning signal representing the low power sent by the communication component 13 through the external terminal 200. When the energy storage 40 uses rechargeable batteries, the user can replace the rechargeable batteries or use the reserved charging interface of the rechargeable batteries to connect to the external power supply for charging when the user knows the warning signal representing the low power sent by the communication component 13 through the external terminal 200.

[0070] In some examples, the monitoring assembly 30 further comprises a torque sensor 31, and the main control assembly 12 further has a signal input port electrically connected with the torque sensor 31 to receive a torque signal fed back by the torque sensor 31, and in the working state, the main control assembly 12 transmits the received torque signal to the communication assembly 13, and the communication assembly 13 is further configured to forward the received torque signal to the external terminal 200.

[0071] In actual application, the torque sensor 31 works under the power supply of the energy storage 40, and when the user holds the wrench 100 to twist the target fastener, the torque sensor 31 feeds back a torque signal, which is received by the monitoring assembly 30 and transmitted to the communication assembly 13 for forwarding to the external terminal 200 by the communication assembly 13. Thus, the workpiece manager using the external terminal 200 can know the actual use of the wrench 100, so as to supervise whether the user as an operator correctly uses the corresponding wrench 100.

[0072] In some examples, as shown in Figure 2 The power supply control circuit 10 further comprises a charging switch 14, which has a first end and a second end, the first end is electrically connected with the energy storage 40, and the second end is electrically connected with the photovoltaic assembly 11. When the charging switch 14 is on, the photovoltaic assembly 11 charges the energy storage 40, and when the charging switch is off, the photovoltaic assembly 11 stops charging the energy storage 40.

[0073] In the present example, the energy storage is a charging battery by default. The two ends of the charging switch 14 are connected with the photovoltaic assembly 11 and the energy storage 40 respectively, and the user can control the on-off of the charging switch 14 according to the needs, so as to realize that the photovoltaic assembly 11 converts light energy into electrical energy and then delivers it to the energy storage 40 for charging, so as to realize emergency charging when the energy storage 40 is insufficient, and to ensure the normal operation of the energy storage 40. When the external power supply is not convenient for charging the energy storage 40 with insufficient power, the user can close the charging switch 14 to charge the energy storage 40 by the photovoltaic assembly 11, as an emergency charging measure for the energy storage 40.

[0074] Further, the main control assembly 12 further has a charging control port. The power supply control circuit 10 further comprises a charging switch 14, which has a first end, a second end and a third end, the first end is electrically connected with the energy storage 40, the second end is electrically connected with the photovoltaic assembly 12, and the third end is electrically connected with the charging control port of the main control assembly 12.

[0075] The master control component 12 controls the first end and the second end of the charging switch 14 to be connected when the remaining power is lower than the preset charging threshold, so as to realize charging of the energy storage component 40 by the photovoltaic component 11; and the master control component 12 controls the first end and the second end of the charging switch 14 to be disconnected when the remaining power is not lower than the preset charging threshold, so as to realize stopping charging of the energy storage component 40 by the photovoltaic component 11.

[0076] The master control component 12 controls the connection between the first end connected with the photovoltaic component 11 and the second end connected with the energy storage component 40 of the charging switch 14 according to the remaining power of the energy storage component 40 detected by the energy storage monitoring port. The charging of the energy storage component 40 by the photovoltaic component 11 is interrupted when the energy storage component 40 has sufficient energy, so as to avoid overloading of the energy storage component 40; and the charging of the energy storage component 40 by the photovoltaic component 11 is automatically controlled by the master control component 12 when the energy storage component 40 has insufficient energy, so as to ensure the energy storage of the energy storage component 40.

[0077] In some examples, the power supply control circuit 10 further comprises a power supply switch 15; the power supply switch 15 has a first end and a second end, the first end is connected with the energy storage component 40, and the second end is connected with the monitoring component 30. When the power supply switch 15 is connected, the energy storage component 40 supplies power to the monitoring component 30; and when the power supply switch 15 is disconnected, the energy storage component 40 stops supplying power to the monitoring component 30.

[0078] In this example, the two ends of the power supply switch 15 are connected with the monitoring component 30 and the energy storage component 40 respectively, and a user can control whether the energy storage component 40 supplies power to the monitoring component 30 by adjusting the connection of the power supply switch 15.

[0079] Further, the master control component 12 further has a power supply control port; the power supply control circuit 10 further comprises a power supply switch 15; the power supply switch 15 has a first end, a second end and a third end, the first end is connected with the energy storage component 40, the second end is connected with the monitoring component 30, and the third end is connected with the power supply control port of the master control component 12.

[0080] In the working state, when the torque signal indicates that the wrench 100 is in the stressed state, the master control component 12 controls the power supply switch 15 to be connected (i.e., the electrical connection between the first end and the second end is conducted), so as to make the energy storage component 40 supply power to the monitoring component 30; and when the torque signal indicates that the wrench 100 is in the non-stressed state and the shutdown trigger time length T 关 is reached, the master control component 12 controls the power supply switch 15 to be disconnected (i.e., the electrical connection between the first end and the second end is disconnected), so as to ensure that the energy storage component 40 stops supplying power to the monitoring component 30.

[0081] In the scheme, the master control assembly 12 controls the power supply switch 15 to be turned on according to the torque signal indicating the force state of the wrench, so that the energy storage member 40 supplies power to the monitoring assembly 30 to ensure the normal work of the monitoring assembly 30; the master control assembly 12 controls the power supply switch 15 to be turned off according to the torque signal indicating that the time length of the non-force state of the wrench 100 reaches the shutdown trigger time length T 关 , the energy storage member 40 stops supplying power to the monitoring assembly 30 to realize automatic stop of power supply of the wrench 100 after the non-force state reaches the shutdown trigger time length T 关 , that is, the electronic components automatically shut down. According to the time length of the non-force state of the wrench 100, the electronic components are automatically shut down, which is more energy-saving for the energy storage member 40 compared with the energy storage member 40 supplying power to the monitoring assembly 30 all the time.

[0082] Further, as shown in Figure 2 , the electronic components further include a human-computer interaction assembly 32, the human-computer interaction assembly 32 is electrically connected with the master control assembly 12, in the working state, the human-computer interaction assembly 32 is used for displaying the current working parameter to the user and receiving the control instruction from the user, and transmitting the control instruction to the master control assembly 12;

[0083] In the working state, the master control assembly 12 is further used for executing the corresponding control operation according to the control instruction and transmitting the current working parameter to the communication assembly 13 according to the preset period, so as to trigger the communication assembly 13 to transfer the current working parameter to the external terminal 200.

[0084] The human-computer interaction assembly 32 is arranged to display the current working parameter, so that the user can fully understand the working state of the wrench 100, and at the same time, the human-computer interaction assembly 32 can also facilitate the user to input the control instruction to the master control assembly 12 and execute the corresponding operation, realizing the manual control of the wrench 100. At the same time, the master control assembly 12 receives the control instruction and executes, and at the same time, the current working parameter is periodically transmitted to the external terminal 200, so that the remote workpiece management personnel can understand the operation of the wrench 100 of the current user, and more conveniently monitor whether the user uses the wrench 100 in accordance with the regulations.

[0085] Further, the working parameter includes the torque value indicated by the torque signal, and when the time indicated by the torque signal that the wrench 100 is in the non-force state reaches the preset sleep trigger time length, the master control assembly 12 interrupts the power supply of the energy storage member 40 to the human-computer interaction assembly 32.

[0086] Specifically, the signal receiving port of the master control assembly 12 is electrically connected with the torque sensor 31 to receive the torque signal; the master control assembly 12 further has a power supply control port; the power supply control circuit 10 further comprises a power supply switch 15; the power supply switch 15 has a first end, a second end, a third end and a fourth end, the first end is electrically connected with the energy storage member 40, the second end is electrically connected with the torque sensor 31, the third end is electrically connected with the power supply control port of the master control assembly 12, and the fourth end is electrically connected with the human-computer interaction assembly 32.

[0087] In the working state, when the torque signal indicates that the wrench 100 is in the force state, the master control assembly 12 controls the power supply switch 15 to conduct between the first end and the second end to realize the power supply of the energy storage member 40 to the torque sensor 31, and controls the power supply switch to conduct between the first end and the fourth end to realize the power supply of the energy storage member 40 to the human-computer interaction assembly 32.

[0088] When the torque signal indicates that the wrench 100 is in the non-force state and the time reaches the shutdown trigger duration T 关 , the master control assembly 12 controls the power supply switch 15 to disconnect the electrical connection between the first end and the second end, and controls the power supply switch to disconnect the electrical connection between the first end and the fourth end, so as to ensure that the energy storage member 40 interrupts the power supply to the torque sensor 31 and the human-computer interaction assembly 32.

[0089] When the torque signal indicates that the wrench 100 is in the non-force state and the time reaches the hibernation trigger duration T 休 , the master control assembly 12 controls the power supply switch 15 to disconnect the electrical connection between the first end and the fourth end, so as to ensure that the energy storage member 40 interrupts the power supply to the human-computer interaction assembly 32, and the hibernation trigger duration T 休 is less than the shutdown trigger duration T 关 .

[0090] In this example, the master control assembly 12 controls the power supply switch 15 to be turned on according to the force state of the wrench 100 indicated by the torque signal, and the energy storage member 40 supplies power to the monitoring assembly 30 comprising the torque sensor 31 and the human-computer interaction assembly 32, so as to ensure the normal work of the monitoring assembly 30. The master control assembly 12 controls the power supply of the energy storage member 40 to the monitoring assembly 30 comprising the torque sensor 31 and the human-computer interaction assembly 32 according to the duration of the wrench 100 in the non-force state indicated by the torque signal, and the specific implementation is that when the torque signal indicates that the wrench 100 is in the non-force state and the time reaches the hibernation trigger duration T 休When the time reaches the shutdown trigger time length Toff, the wrench 100 enters the shutdown state, and the torque sensor 31 and the human-computer interaction assembly 32 both stop working. Compared with the traditional energy storage component 40 supplying power to the torque sensor 31 and the human-computer interaction assembly 32 throughout the process, the wrench 100 of the present case realizes automatic hibernation and automatic shutdown, saves the energy of the energy storage component 40 as much as possible, and avoids energy waste.

[0091] In some examples, as shown in FIG. 1, the third end of the charging switch 14 is electrically connected with the charging control port of the master control assembly 12, and the third end of the power supply switch 15 is electrically connected with the power supply control port of the master control assembly 12. Figure 2 As shown in FIG. 1, the third end of the charging switch 14 is electrically connected with the charging control port of the master control assembly 12, and the third end of the power supply switch 15 is electrically connected with the power supply control port of the master control assembly 12.

[0092] In the present example, the user remotely controls the on-off of the charging switch through the communication assembly 13 and the master control assembly 12, realizing remote control of charging and discharging of the energy storage component 40. Specifically, the control instruction includes one of a charging instruction, a charging interruption instruction, a working instruction, a shutdown instruction, and a hibernation instruction.

[0093] If the control instruction received by the master control assembly 12 through the communication assembly 13 is the charging instruction, the master control assembly 12 controls the charging switch 14 to be conductive through the charging control port, realizing charging of the energy storage component 40 by the photovoltaic assembly 11. If the control instruction received by the master control assembly 12 through the communication assembly 13 is the charging interruption instruction, the master control assembly 12 controls the charging switch 14 to be disconnected through the charging control port, and the photovoltaic assembly 11 interrupts charging of the energy storage component 40.

[0094] If the control instruction received by the master control assembly 12 through the communication assembly 13 is the working instruction, the master control assembly 12 controls the power supply switch 15 to be conductive through the power supply control port, and the energy storage component 40 supplies power to the monitoring assembly 30, so that the monitoring assembly 30 resumes / retains the normal working state. If the control instruction received by the master control assembly 12 through the communication assembly 13 is the shutdown instruction, the master control assembly 12 controls the power supply switch 15 to be completely disconnected through the power supply control port, and the energy storage component 40 interrupts power supply to the monitoring assembly 30, so that the torque sensor 31 and the human-computer interaction assembly 32 in the monitoring assembly 30 both stop working.

[0095] If the control command received by the main control component 12 through the communication component 13 is a sleep command, the main control component 12 controls the power supply switch 15 through the power supply control port to disconnect from the human-machine interface component 32, while maintaining the connection with the torque sensor 31. This causes the human-machine interface component 32 in the electronic components to stop working, while the torque sensor 31 continues to work.

[0096] Furthermore, the human-computer interaction component 32 includes a button component and a display screen. The display screen is connected to the main control component 12 and is used to display the current working parameters to the user and receive control commands from the user; the button component is used to receive the user's control commands and transmit the control commands to the main control component 12, so that the main control component 12 can perform corresponding operations according to the control commands, and transmit the current working parameters to the communication component 13 according to a preset period, so as to trigger the communication component 13 to send the current working parameters to the external terminal 200.

[0097] Specifically, the user inputs operation commands via a button component, which outputs these commands to the main control component 12. The main control component 12 then controls the on / off states of the charging switch 14 and the power supply switch 15 based on the received commands. Control commands include one of the following: charging command, charging interruption command, working command, power-off command, and sleep command. If the main control component 12 receives a charging command, it controls the charging switch 14 to turn on, allowing the photovoltaic module 11 to charge the energy storage device 40. If the main control component 12 receives a charging interruption command, it controls the charging switch 14 to turn off, stopping the photovoltaic module 11 from charging the energy storage device 40. If the main control component 12 receives a working command, it controls the power supply switch 15 to turn on, allowing the energy storage device 40 to supply power to the torque sensor 31 and the human-machine interface component 32 in the monitoring component 30. All components remain operational. If the main control component 12 receives a shutdown command, the power supply switch 15 is completely disconnected, and the energy storage component 40 stops supplying power to the torque sensor 31 and the human-machine interface component 32 in the monitoring component 30. Both the torque sensor 31 and the human-machine interface component 32 are then shut down. If the main control component receives a hibernation command, the power supply switch 15 is kept electrically connected to the torque sensor 31, while the power supply switch 15 is disconnected from the human-machine interface component. The energy storage component 40 supplies power only to the torque sensor 31, and the human-machine interface component 32 is shut down.

[0098] In some examples, such as Figure 3 As shown, the power supply control circuit 10 also includes a preprocessing circuit 16 containing an amplifier. The preprocessing circuit 16 has a first terminal and a second terminal. The first terminal is used to be electrically connected to the torque sensor 31 to receive the raw torque signal fed back by the torque sensor 31. The second terminal is electrically connected to the signal receiving port of the main control component 12 to output the preprocessed torque signal.

[0099] The preprocessing circuit amplifies the raw torque signal output by the torque sensor 31, and then transmits the preprocessed torque signal to the main control component. The preprocessed torque signal can carry more information, making the monitoring signal more accurate and reliable for monitoring the status of electronic components.

[0100] Second embodiment:

[0101] A second embodiment of the present invention provides a wrench, such as Figure 4 As shown, this embodiment is a specific example of the module diagram of the first embodiment. The specific details of the implementation of the first embodiment are still valid in this embodiment, and will not be repeated here.

[0102] like Figure 4 As shown, the photovoltaic module uses a photovoltaic panel, the positioning module uses a positioning chip, the main control module uses a main control chip, the communication module includes a communication unit, the preprocessing circuit includes an amplifier and an A / D converter, the human-machine interaction module includes a display screen, and the torque sensor is composed of R1, R2, R3 and R4.

[0103] During use, the photovoltaic panel supplies power to the positioning chip and communication unit, enabling them to operate regardless of the battery's charge level. The positioning chip periodically detects the position information of the wrench and transmits it to the communication unit, which then relays this position information to an external terminal. This ensures stable operation of the positioning chip and communication unit, allowing them to consistently measure the remaining battery charge.

[0104] In one example, the photovoltaic module uses a photovoltaic panel, the positioning module uses a positioning chip, and the main control module uses a main control chip (such as a microprocessor MCU). The photovoltaic panel is directly electrically connected to the positioning chip, the main control chip, and the communication component, providing continuous power to the operation of the positioning chip, the communication component, and the main control chip. At the same time, the photovoltaic panel also supplies power to the rechargeable battery, which is an energy storage device, through the charging switch D1 to charge the rechargeable battery.

[0105] In one example, the two ends of the charging switch D1 are electrically connected to the photovoltaic panel and the rechargeable battery, respectively. Users can manually control whether the photovoltaic panel charges the rechargeable battery by opening and closing the charging switch D1.

[0106] As an alternative example, such as Figure 5As shown, the charging switch D1 can also have three terminals, the first terminal is electrically connected with the photovoltaic panel, the second terminal is electrically connected with the charging battery, and the third terminal is electrically connected with the master control chip. The master control chip controls whether the first terminal and the second terminal of the charging switch D1 are conductive or not through the third terminal of the charging switch D1 according to the instructions received by the master control chip. Specifically, when the instruction received by the master control chip is a charging instruction, the first terminal and the second terminal of the charging switch D1 are controlled to be conductive through the third terminal of the charging switch D1, so that the photovoltaic panel charges the charging battery.

[0107] In one example, the master control assembly includes a master control chip, which can be implemented by a microprocessor. The first port of the microprocessor is electrically connected with the photovoltaic panel as a power supply port. The second port of the microprocessor is electrically connected with the charging battery as an energy storage monitoring port, which is used to periodically detect the remaining power of the charging battery. The third port of the microprocessor is used to receive the torque signal transmitted by the torque sensor as a signal receiving port. The fourth port of the microprocessor is electrically connected with the communication assembly as a communication port. The fifth port of the microprocessor is electrically connected with the third terminal of the charging switch D1 as a charging control port. The seventh port of the microprocessor is electrically connected with the power supply switch (including D2 and D3) as a power supply control port.

[0108] In one example, the communication assembly includes a communication chip, which can be implemented by a Bluetooth communication chip, a wifi communication chip, a USB communication port for information transmission through USB protocol, a zigbee chip in a wireless self-organizing network, or the like. The communication chip can be implemented by one type of communication chip, or multiple types of communication chips can be used to form the communication assembly as an important component of the communication circuit. The first port of the communication chip is used to communicate with the external terminal 200 as a transceiver port, which is used to transmit the positioning information from the positioning chip, the remaining power of the charging battery from the master control chip, and the torque information from the torque sensor forwarded by the master control chip. The second port of the communication chip is connected with the master control chip as another transceiver port, which is used to forward the control instruction from the external terminal 200 to the master control chip. The third port of the communication chip is electrically connected with the positioning chip as a receiving port, which is used to receive the position information transmitted by the positioning chip.

[0109] In one example, the energy storage member is implemented by a charging battery. In addition, the energy storage member can also be other types of recyclable batteries or disposable batteries, such as dry batteries.

[0110] In one example, the positioning circuit adopts a positioning chip, which is a chip for satellite positioning by using Beidou. After locking the position information of the wrench, the positioning chip sends the position information to the communication unit, which forwards the position information to an external terminal in communication connection therewith. Through the external terminal, the user can know the current position of the corresponding wrench.

[0111] In one example, the torque sensor is composed of R1, R2, R3 and R4. The pre-processing circuit is located between the sensor and the master control chip, and includes an amplifier and an A / D conversion chip. Two input ends of the amplifier are connected to the positive and negative poles of the torque sensor, respectively. The output end of the amplifier is connected to the input end of the A / D conversion chip, and the output end of the A / D conversion chip is connected to the input end of the master control chip.

[0112] In one example, the power supply switch is composed of D2 and D3. D2 is a power supply master switch, and D3 is a power supply sub-switch. D2 has three terminals. The first terminal of D2 is connected to the charging battery, the second terminal of D2 is connected to the sensor, and the third terminal of D2 is a control terminal connected to the power supply control terminal of the master control chip. D3 has three terminals. The first terminal of D3 is connected to the display screen, the second terminal of D3 is connected to the second terminal of D2, and the third terminal of D3 is a control terminal connected to the power supply control terminal of the master control chip.

[0113] In order to ensure that the control of D2 and D3 does not interfere with each other, when the master control chip controls the power supply switch through the power supply control terminal, two types of electrical signals can be set for control. For example, D2 will only be turned on under high-frequency pulse, and D3 will only be turned on under low-frequency pulse. Alternatively, the master control chip can set two power supply control terminals, one of which is connected to D2 and the other of which is connected to D3, to achieve separate control of the switches D2 and D3. In addition, the power supply switch can also be set as other various switch circuits.

[0114] In one example, the human-computer interaction assembly includes a display screen. The charging battery is directly connected to the display screen and the torque sensor, respectively, to directly supply power to the display screen and the torque sensor. The display end of the display screen is connected to the master control chip to display the torque information from the torque sensor, the control instructions from the communication unit, and the remaining capacity of the monitored charging battery sent by the master control chip.

[0115] In another example, the power supply switch is composed of D2. D2 has two terminals. The first terminal of D2 is connected to the charging battery, and the second terminal of D2 is connected to the display screen and the torque sensor, respectively. Alternatively, the power supply switch D2 can also have three terminals. The first terminal of D2 is connected to the charging battery, the second terminal of D2 is connected to the display screen and the sensor, respectively, and the third terminal of D2 is connected to the power supply control terminal of the master control chip.

[0116] Third embodiment:

[0117] The third embodiment of the present invention provides a wrench, such as Figures 6-9 As shown, the device includes a connecting portion 101, a main body portion 102, and a force-receiving portion 103. The left end of the connecting portion 101 is used to engage with a target fastener, and the right end of the connecting portion 101 is connected to the left end of the main body portion 102. The right end of the main body portion 102 is connected to the left end of the force-receiving portion 103, which is used to receive torque applied by the user. The positioning component 20 and the power supply control circuit 10 are both disposed on the main body portion 102. The cavity containing the energy storage component 40 is located within the force-receiving portion 103, or within the main body portion 102, or partially within the force-receiving portion 103 and partially within the main body portion 102.

[0118] Specifically, fasteners are typically parts that require a wrench to tighten, such as hexagonal nuts. In use, the user partially mounts the wrench's connecting part 101 around the fastener, allowing the fastener to engage with the connecting part. The user then applies external force by holding the force-bearing part 103, thereby rotating the wrench around the connecting part 101 using a lever principle. This results in a more secure connection between the fastener and the workpiece to be tightened. For example, the workpiece to be tightened is a screw, the fastener is a hexagonal nut that threads with the screw, and the connecting part 101 uses a ratchet tenon.

[0119] In some examples, the connection between the connecting part 101 and the main body 102 is a fixed connection to ensure the stability of the connection between the connecting part 101 and the main body 102, and to ensure that the wrench can better withstand external forces.

[0120] In other examples, the connection between the connecting part 101 and the main body 102 can also be a detachable connection, allowing one main body 102 to be connected to connecting parts 101 of various specifications during use. In practical applications, the user can select the appropriate connecting part 101 based on the target fastener and then connect it to the main body 102. This design broadens the application range of the connecting part 101 for fasteners, enabling it to serve various types and specifications of fasteners.

[0121] In some examples, such as Figure 6 As shown, the main body 102 includes an extension 1021 and a carrier 1022. The left end of the extension 1021 is used to connect with the connecting part 101, and the right end of the extension 1021 is fixedly connected to the carrier 1022.

[0122] like Figure 7As shown, the left end top of the extension piece 1021 is provided with a cavity, the top of the cavity is paved with a strain gauge 311, and a torsion sensing body 312 is arranged in the cavity, and the strain gauge 311 and the torsion sensing body 312 jointly constitute a torsion sensor 31. In actual application, the strain gauge 311 senses the feedback stress generated by the user's force, transmits the feedback stress as torsion information to a main control chip in the power supply control circuit as a main control component, and then the main control chip displays the feedback stress on the display screen 221 of the man-machine interaction circuit 22 or sends the feedback stress to the externally connected terminal 200 through the communication component to inform the workpiece manager / user of the use status of the wrench, so as to remotely monitor the working state of the workpiece.

[0123] As shown in the figure, Figure 8 As shown, the carrier piece 1022 is provided with a content cavity, and a main control circuit board is arranged in the content cavity, and a power supply control circuit and a positioning component are arranged in the main control circuit board, and the charging switch, the main control component, the communication component and the power supply switch are all arranged on the main control circuit board and are all located in the content cavity.

[0124] In some examples, the monitoring assembly 30 includes a man-machine interaction assembly 32 and a torsion sensor 31, the torsion sensor 31 is installed in the cavity of the left end of the extension piece 1021 of the main body part 102 (the end connected with the connecting part 101), and the man-machine interaction assembly 32 is installed in the right end of the carrier piece 1022 of the main body part 102 (the end connected with the force receiving part 103).

[0125] The man-machine interaction assembly 32 includes a display screen 321 and a button 322, the display screen 321 and the button 322 are both arranged above the main control circuit board of the content cavity in the carrier piece 1022, the display screen 321 is arranged on the left side of the button 322, the power supply end of the display screen 321 is extended by a power transmission line, the power supply end is used for electrically connecting with the energy storage piece 40 to be powered by the energy storage piece 40, and the display screen 321 is electrically connected with a main control chip (MCU) to display feedback information from the torsion sensor 31, control instructions from the communication unit and the remaining capacity of the monitored energy storage piece 40.

[0126] The power supply end of the button 322 is extended by a power transmission line and is electrically connected with the energy storage piece 40 to be powered by the energy storage piece 40, the output end of the button 322 is connected with the input end of the main control chip, and the button 322 inputs control instructions to the main control chip when the energy storage piece 40 normally supplies power, so that the main control chip performs corresponding operations according to the control instructions. In some examples, the control instructions can also be received by the communication unit and forwarded to the main control chip by the externally connected terminal.

[0127] The specific button 322 includes five buttons: "P", "Up", "Down", "On", and "Menu". Specifically: The "P" button sends a first signal to the main control chip. Upon receiving the first signal, the main control chip switches the torque signal to torque units and sends it to the display screen 321 for display. The "Menu" button sends a second signal to the main control chip. Upon receiving the second signal, the main control chip controls the display screen to enter the menu interface. If the display screen is already in the menu interface, the settings are confirmed and saved. The "Up" button sends a third signal, and the "Down" button sends a fourth signal. Upon receiving either the third or fourth signal, the main control chip controls the display screen to switch options within the menu interface. If the display screen is in the parameter adjustment interface, the parameters are adjusted; if the display screen is in the preset interface, the preset data group is switched. The "On" button controls the power switch. Specifically, the "On" button sends a power-on signal to the main control chip. Upon receiving the power-on signal, the main control chip controls all power switches to close, and the rechargeable battery powers the torque sensor 31 and the display screen 321 in the human-machine interface component.

[0128] It is worth noting that the display screen 321 in the human-computer interaction component 32 must be turned on when the power switch is closed (the wrench is in the working state), while the button 322 is always electrically connected to the rechargeable battery (the wrench is in the working state, sleep state, and power-off state).

[0129] In some examples, the cavity for supporting the energy storage component 40 can be located in the force-bearing part 103 (not shown in the figure) or in the main body (e.g. Figure 9 As shown), it can also be located partly within the main body and partly within the load-bearing part (such as...). Figure 8 (As shown). The energy storage device 40 can be set in various ways and is not limited to a fixed position. The energy storage device 40 can also be set in a certain moving mechanism to provide power to the monitoring components (including torque sensors and human-machine interaction components) only when in use.

[0130] Specifically, such as Figure 8 As shown, part of the cavity for storing the energy storage component 40 is located in the force-bearing part, and the other part is located in the carrier component. If the energy storage component 40 is replaceable, in order to facilitate the storage and retrieval of the energy storage component, this invention preferably provides a cover that can cover the cavity at the part where the main body and the force-bearing part are connected. The cover can be in the form of a flip cover, a detachable form, a sliding form, etc., to cover the cavity and thus form a closed or semi-closed space with the cavity.

[0131] If the energy storage component 40 is non-replaceable, a rechargeable battery is preferred. A charging port or charging cable can be provided at the tail of the force-bearing part 103 to be electrically connected to the rechargeable battery to provide conventional power. The charging port can also be set as a wireless charging receiver so that users can charge the rechargeable battery wirelessly.

[0132] The energy storage component 40 uses a battery or a rechargeable battery and is disposed in a cavity within the force-receiving part 103. If the energy storage component 40 is replaceable, the cavity of the force-receiving part 103 is connected to the outside, and the surface of the force-receiving part 103 is provided with a cover that can close the cavity. If the energy storage component 40 is non-replaceable, a rechargeable battery is preferred. A charging port or charging cable can be provided at the tail of the force-receiving part 103 to electrically connect to the rechargeable battery and provide conventional power to it. The charging port can also be configured as a wireless charging receiver, allowing users to charge the rechargeable battery wirelessly.

[0133] Another specific example, such as Figure 9 As shown, the carrier 1021 is also provided with a cavity for placing the energy storage component 40. The cavity is in communication with the inner cavity, and the energy storage component in the cavity is electrically connected to the display screen and buttons on the inner cavity.

[0134] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
