[0025] As Figure 7 shown, it is a device usage state diagram, the hand brake 10 is a device with a rotatable operation disc, by rotating the operation disc, the opening or closing of the brake function can be realized, for example, the hand brake of the train: used for preventing the train from sliding when stopping. Traditionally, it is a hand wheel that needs to be rotated manually, and the brake force is transmitted to the wheels of the train through chain and gear mechanism.
[0026] Or the hand brake 10 is a part of a mechanical system, which contains a working component that can be adjusted manually, such as adjusting tension, position, etc. Or it is a kind of manual valve, which can be opened or closed by rotating the hand wheel or operating rod, so as to allow or prevent the medium from passing through the pipeline.
[0027] In some industrial machinery and equipment, the hand brake can refer to any device that needs to be manually operated to brake or lock the moving parts. For example, hand brakes may be used on some machine tools, elevators or other equipment that need to control the movement or stop accurately.
[0028] As Figure 1 and Figure 2As shown, a portable hand brake motor electric tool power-assisted device includes a movable rod 2, a positioning locking part 4, and a motor 6. The end of the movable rod 2 is fixedly connected with a counteracting clamp jaw 1, which is used to clamp the hand brake motor.
[0029] The fixed-length hand tool appears to be not flexible enough to adapt to various complex working environments. In order to face diversified application scenarios and space limitations, the movable rod 2 is slidably connected with an adjusting rod 3. This allows users to adjust the overall length of the device according to actual needs. Through the sliding connection, the position of the movable rod 2 relative to the adjusting rod 3 can be easily changed, thereby adapting to different working environments or operation requirements.
[0030] The positioning locking part 4 is arranged on the movable rod 2 and is used to lock the movable rod 2 and the adjusting rod 3. In cooperation with the positioning locking part 4, the movable rod 2 and the adjusting rod 3 can be firmly locked after being adjusted to the required length, ensuring that accidental sliding or loosening does not occur during operation, thereby enhancing the safety and stability of use.
[0031] The output end of the motor 6 is connected with a rotary ratchet 9 through a speed reducer 8, and a large-capacity lithium battery 5 is connected to the motor 6. The speed reducer 8 can increase the torque output of the motor. This means that even if the power of the motor itself is limited, through the amplification effect of the reduction ratio, enough power can be provided to drive the rotary ratchet 9, thereby more effectively operating the hand brake motor. Through the reduction, the smoothness and control accuracy of the rotation of the rotary ratchet 9 are also improved, making the operation more delicate.
[0032] The large-capacity lithium battery 5 provides a durable power source for the motor, ensuring long-term work requirements. This is particularly important for outdoor or places far from power sources, reducing the need for frequent battery replacement or charging due to insufficient power.
[0033] A forward-reverse dial switch 7 and a start-stop switch 61 are arranged on the motor 6. The forward-reverse dial switch 7 allows users to easily switch the rotation direction of the motor. This is very useful for hand brake motors 10 that need to be operated in different directions, without the need to manually adjust the direction of the tool, just dial the switch. The start-stop switch 61 provides a simple and direct method to start and stop the operation of the motor, so that users can accurately control the start and end of the work process, improving the convenience and flexibility of operation.
[0034] The movable rod 2 is sleeved on the adjusting rod 3, and the adjusting rod 3 is provided with holes 31. The number of the holes 31 is at least two, and they are arranged along the length direction of the adjusting rod 3. By arranging multiple holes 31 on the adjusting rod 3, the user can adjust the relative position between the movable rod 2 and the adjusting rod 3 according to actual needs, thereby changing the effective length of the entire assisting device. This allows the device to adapt to different operating requirements of height or distance. When the positioning locking piece 4 is inserted into the selected hole 31, it can ensure that the movable rod 2 and the adjusting rod 3 do not slide unnecessarily, ensuring the safety and stability of use.
[0035] As shown in Figure 3 , the holes 31 are continuous with each other, which allows the relative position between the movable rod 2 and the adjusting rod 3 to be adjusted more finely and continuously. Due to the continuity between the holes, the user can more easily find a suitable hole to meet the length requirement without having to compromise on a few fixed positions. This design greatly improves the flexibility of the device, making it suitable for more different application scenarios.
[0036] The holes 31 have regular shapes such as circular, elliptical or polygonal, and are preferably circular.
[0037] As shown in Figure 4 and Figure 6 , the movable rod 2 is provided with a mounting hole 21, and the positioning locking piece 4 is arranged in the mounting hole 21. The positioning locking piece 4 includes a positioning sleeve 41 and a plug 42. The positioning sleeve 41 is fixedly connected to the movable rod 2, and the plug 42 is in sliding connection with the positioning sleeve 41. The plug 42 is provided with a handle 43.
[0038] As shown in Figure 5 , the design of the positioning locking piece 4 ensures the firm connection between the movable rod 2 and the adjusting rod 3. When the plug 42 is inserted into the positioning sleeve 41 and then into the hole 31 on the adjusting rod 3, it can prevent the movable rod 2 and the adjusting rod 3 from sliding relative to each other, ensuring stability during operation. Since the plug 42 is in sliding connection with the positioning sleeve 41, the user can easily pull out or insert the plug to adjust the position of the adjusting rod 3. The presence of the handle 43 further simplifies this operation.
[0039] Alternatively, the positioning locking piece 4 uses a bolt tightening method to lock the movable rod 2 and the adjusting rod 3. The bolt tightening method can provide strong clamping force to ensure that the movable rod 2 and the adjusting rod 3 do not slide relative to each other. This firm connection is particularly important for situations that require the application of a large torque or operation in an unstable environment.
[0040] The device is externally provided with a shell, and the material of the shell is magnesium-aluminum alloy such as M2M or titanium alloy. Magnesium-aluminum alloy is a very light metal material, which can significantly reduce the overall weight of the device. This is particularly important for tools that need to be held or carried for a long time, which can reduce the fatigue of the user. Titanium alloy not only has extremely light weight, but also has excellent strength, and its strength-to-weight ratio is much higher than that of most other metal materials, which is very suitable for high-end and high-performance handheld tools.
[0041] The shell is provided with an OLED display screen 62, a back strap 63 and a foldable handle 64. The OLED display screen 62 can display working state information such as the current motor working mode, the remaining power and the like, and can also set tool parameters, torque, angle, speed, communication mode and the like on the screen. The OLED display screen 62 is a color digital display screen, which can display torque in real time under low temperature conditions, so that the user can know the state of the device at any time, and ensure the accuracy and safety of the operation. The design of the back strap 63 makes the device easier to carry, especially in the case of long-time movement or frequent change of working place, which greatly improves the portability of the device. When not in use, the foldable handle 64 can be folded up, reducing the overall volume of the device, and facilitating storage and transportation.
[0042] The device is also provided with a control system, which can realize real-time torque storage function and torque adjustment setting, and can also support Bluetooth and wifi connection, provide an installable system, realize data recording tracking and downloading.
[0043] The above-mentioned installation system can be an Android / iPhone system, or a dedicated APP to receive data.
[0044] The device parameters are as follows: output torque: 300N.M (maximum output torque); rated voltage: ≤36V; output speed: 18-30r / min (no-load speed); battery capacity: 8000mAh; charging time: about 200min; number of uses: more than 150 times per single charging; torque accuracy: tightening accuracy level ±4%, repeat accuracy ±2%.
[0045] The communication mode can adopt serial communication interface (Serial Communication Interface, SCI), Bluetooth, wifi and the like to realize bit-by-bit sending and receiving of data. The above-mentioned communication mode is known to those skilled in the art, and therefore will not be described again.
[0046] The following are the steps of the working process of the portable hand brake motor electric tool assisting device:
[0047] Preparation: Ensure that all components are in good condition, including the motor 6, the battery 5 and the mechanical connection parts. Check whether the large-capacity lithium battery 5 is fully charged, and confirm that all switches are in the off state.
[0048] Adjust the length of the movable rod: first, clamp the reaction jaw 1 on the hand brake 10, and adjust the distance between the movable rod 2 and the adjusting rod 3 according to the actual work needs. By sliding the movable rod 2 to the appropriate position, the rotating ratchet 9 can be accurately clamped into the operation disc of the hand brake 10. When the appropriate length is found, use the positioning locking part 4 to fix the movable rod 2 and the adjusting rod 3. The specific operation is: insert the latch 42 into the corresponding hole 31. Or, if the bolt tightening method is used, directly tighten the bolt to achieve locking.
[0049] Operation stage: after confirming that the rotating ratchet 9 has been correctly clamped into the operation disc of the hand brake 10, operate the start-stop switch 61 to start the motor 6. At this time, the motor starts to work and drives the rotating ratchet 9 to rotate through the speed reducer 8, thereby driving the hand brake 10 to rotate. If the hand brake 10 needs to rotate in the opposite direction, the forward-reverse switch 7 can be operated to change the rotation direction of the motor 6. In this way, clockwise or counterclockwise switching can be easily realized to meet different operation needs. During the entire operation process, the user can monitor the state information of the device in real time through the OLED display screen 62, such as the working mode of the motor and the remaining power. This helps to timely adjust the operation strategy and ensure the smooth progress of the work.
[0050] End stage: after completing the required hand brake operation, press the start-stop switch 61 again to stop the work of the motor 6. Ensure that all switches are closed, operate the positioning locking part 4 to make the movable rod 2 and the adjusting rod 3 no longer locked, and carefully remove the reaction jaw 1 and the rotating ratchet 9 from the hand brake 10. Finally, fold the handle 64 and store the entire device properly in the designated location for next use.
[0051] Preferably, the motor 6 is a low-temperature motor that can work in an extremely cold low-temperature environment of-40°, increasing the service life and improving the use efficiency. The battery cell and the entire device can also withstand a working environment of-40°. The low-temperature motor, battery cell, and low-temperature material of the shell are components known to those skilled in the art, so they will not be described again.
[0052] It should be noted that the hand brake, the reaction jaw 1, the large-capacity lithium battery 5, the motor 6, the speed reducer 8, the OLED display screen, the back strap, the foldable handle, and the control system in the embodiment are all general standard parts or components known to those skilled in the art, and their structures and principles can be known by those skilled in the art through technical manuals or through conventional experimental methods.
