Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0024] The inventors of this solution discovered that in existing technologies, the operating handles of lifting mechanisms are mostly external buttons or joysticks, resulting in limited functionality and a single mode. Furthermore, the weighing structure and control panel of traditional lifting devices are placed separately. The various functions of the control handle are not well integrated; for example, the weighing unit, hanging unit, connecting unit, control unit, and operating unit are all placed independently, occupying a significant amount of space. The operating units are mostly joysticks or buttons, offering limited human-machine interaction and low operational precision. Currently, there are no products on the market that fully integrate these functions. Moreover, there are no safety warning measures for the connecting and hanging structure. This embodiment provides the following solution:

[0025] like Figs. 1 to 4 As shown, this embodiment provides a control handle, including a handle body 1, with a grip 2 connected to the handle body 1. The handle body 1 is provided with a rotatable electric slip ring 3, a cable interface 4, and a first force detection device 5. The cable interface 4 corresponds to the output cable at one end of the electric slip ring 3, and the grip 2 is provided with a movable push block 6 corresponding to the first force detection device 5.

[0026] It should be noted that the cable in cable interface 4 is connected to the output cable at one end of the slip ring 3, and the external cable only needs to be connected to cable interface 4. When the hand grips handle 2, it needs to be rotated according to the needs of the scenario. The slip ring 3 allows the handle 2 to rotate freely while maintaining the connection between the cable and the internal signal line, improving the adaptability of the entire handle in different scenarios. The first force detection device 5 can be a pressure sensor. When the operator grips handle 2 with their palm, when the thumb pushes the push block 6, the push block 6 generates a pressure signal to the first force detection device 5, which can then send a control signal. For example, this control signal can be a lifting control signal, controlling the lifting mechanism to perform lifting operations, thus making the operation more stable and precise. This method allows for manual one-handed operation, with the palm gripping for stability, greatly improving operational accuracy and stability.

[0027] In some embodiments, the handle body 1 includes a handle housing 11, a rotating housing 12, an upper end cover 13, and a lower end cover 14. One end of the rotating housing 12 is connected to an electric slip ring 3, and the other end of the rotating housing 12 is connected to the upper end cover 13. A cable interface 4 is disposed on one side of the rotating housing 12. A first force detection device 5 is mounted inside the lower end cover 14. A push block 6 is bolted to the first force detection device 5. The lower end cover 14 is connected to the bottom of the handle housing 11. The grip 2 passes through the push block 6, the lower end cover 14, and the first force detection device 5 and is connected to the bottom of the handle housing 11.

[0028] It should be noted that a control box is located inside the handle housing 11. The control box is sealed with a rubber ring to prevent dust and other liquids from entering its cavity. Various signal wires are housed within the control box. The handle housing 11 is made of metal. The outer ring of the first force detection device 5 is pressed firmly against the bottom of the handle housing 11, while the inner ring makes only a loose contact. Wiring runs from an opening in the handle housing 11 to the control circuit board 8 inside the handle housing 11. When the thumb pushes the push block 6, the push block 6 presses the first force detection device 5 against the bottom of the handle housing 11, generating a pressure signal, which then sends a control signal.

[0029] In some embodiments, a cable clamp 133 is provided on one side of the upper cover 13 for fixing signal lines and power lines hanging from the lifting mechanism or the outside.

[0030] In some embodiments, the upper cover 13 is provided with a spring-back connecting block 131, and a position detection device 132 is provided below the upper cover 13, with the detection end of the position detection device 132 contacting the connecting block 131.

[0031] It should be noted that a spring 134 is fitted onto the connecting block 131. One end of the spring 134 is connected to the upper end cover 13, and the other end is connected to the bottom of the connecting block 131. A retaining ring 135 is installed above the connecting block 131 to prevent the connecting block 131 from excessively springing down due to the force of the spring 134. Specifically, the position detection device 132 can be a limit switch. The connecting block 131 serves as a lifting point for the wire rope, i.e., the connecting block 131 is connected to the wire rope of the winch, and at this time, the connecting block 131 is under load. When the load is lost, the position of the connecting block 131 relative to the position detection device 132 changes under the drive of the spring 134. After detecting the abnormality, the position detection device 132 sends a stop signal to the winch.

[0032] In some embodiments, the rotating housing 12 includes a bearing retainer 121, a first bearing 122, a bearing washer 123, a second bearing 124, and a rotating sleeve 125. The first bearing 122, bearing washer 123, and second bearing 124 are sequentially stacked at the bottom of the rotating housing 12. The rotating sleeve 125 is fitted onto the first bearing 122, bearing washer 123, and second bearing 124, and connected to the handle housing 11. The bearing retainer 121 is connected to the inner wall of the rotating housing 12, and one end of the bearing retainer 121 abuts against the first bearing 122. An electric slip ring 3 is connected to the bearing retainer 121, and the output cable at the other end of the electric slip ring 3 passes through the rotating sleeve 125 to the inside of the handle housing 11.

[0033] It should be noted that both ends of the bearing fixing member 121 are connected to the inner wall of the rotating housing 12 via the first set screw 1211. The rotating sleeve 125 does not contact the bearing fixing member 121 and extends into the handle housing 11, thereby allowing the cable of the electric slip ring 3 to pass more stably into the handle housing 11. Due to the action of the first bearing 122 and the second bearing 124, the rotating housing 12 is rotatable relative to the handle housing 11.

[0034] In some embodiments, the rotating sleeve 125 is connected to a second force detection device 1251, and the detection end of the second force detection device 1251 contacts the inner wall of the handle housing 11.

[0035] It should be noted that the second force detection device 1251 uses a load cell. When an object is hung under the handle 2, the handle housing 11 is pressed down by the weight of the object, which causes the electrical signal generated by the detection end of the load cell to change and output the weight signal of the object.

[0036] In some embodiments, the handle 2 has an axial structure, and the upper and lower ends of the push block 6 are respectively provided with a first sliding sleeve 61 and a second sliding sleeve 62. The first sliding sleeve 61 and the second sliding sleeve 62 are slidably connected to the handle 2, thereby making the push block slide more smoothly on the handle, improving the accuracy of movement, and further improving the control accuracy.

[0037] In some embodiments, the handle 2 is connected to a grip sleeve 21, which is fixed to the handle 2 by a second set screw 213. The grip sleeve 21 is located below the push block 6. The grip sleeve 21 has protrusions 211 at both ends and annular grooves 212 in the middle portion, thereby increasing friction, preventing slippage during use, limiting the operator's grip position, and preventing accidental contact with the push block 6.

[0038] In some embodiments, one side of the handle housing 11 is provided with a display screen 111 and a plurality of control buttons 112, and the other side of the handle housing is provided with at least one external interface 113.

[0039] It should be noted that the display screen 111 is used to display relevant operating parameters, and the control buttons 112 are used to input operating parameters, such as ascent speed and maximum load capacity. The external interface 113 can be an aviation plug interface for expanding functions, such as extending control buttons and additional sensor control. Additionally, an extra knob opening is provided on the back as an expansion hole for non-electrically controlled interfaces.

[0040] In some embodiments, the end of the handle 2 is provided with an external thread 22, which can be used to attach a hook or other tools, increasing expandability.

[0041] In summary, the embodiments of this utility model provide a control handle that maintains the connection between the cable and the signal line while allowing the handle to rotate without restriction via an electric slip ring, achieves weighing function through a weighing sensor inside the handle, and outputs lifting signals through a pressure sensor and a push block, thereby greatly improving the adaptability and operational accuracy of the handle.

[0042] The above description is merely a specific embodiment of this application, and the scope of protection of this application is not limited thereto. Those skilled in the art can make changes or substitutions within the technical scope disclosed in this application, and all such changes or substitutions should be within the scope of protection of this application.

[0043] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are meant to be within the scope of this invention and form different embodiments.

[0044] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
