This can severely damage the lights, affecting their normal use and lifespan. Specifically, when the light makes contact with an obstacle during descent, the motor continues to run, causing the light to press down further. This exerts a significant impact on both the obstacle and the light itself, potentially loosening or damaging internal components, thus affecting the light's normal operation and increasing maintenance costs.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0029] like Figure 1 As shown, an anti-collision sensing device 10 according to an embodiment of this disclosure includes a rotating structure 100, a base structure 200, a transmission sensing structure 300, and a suspension rope 400, which can be referred to in conjunction with the above. Figure 2 and Figure 3 The base structure 200 includes a limiting base 210, a first support base 220, and a second support base 230. The first support base 220 and the second support base 230 are respectively disposed on both sides of the limiting base 210. The transmission sensing structure 300 includes an elastic support component 310 and a switch sensing component 320. The first support base 220 has a first receiving cavity 2201, and the second support base 230 has a second receiving cavity 2301. The switch sensing component 320 is disposed in the first receiving cavity 2201, and the elastic support component 310 is disposed in the second receiving cavity 2301.
[0030] The limiting base 210 has a first rotating through hole 2101 and a second rotating through hole 2102 symmetrically arranged on its two side walls. The rotating structure 100 passes through the first rotating through hole 2101 and the second rotating through hole 2102. The rotating structure 100 is rotatably connected to the elastic support component 310 and the switch sensing component 320 respectively. The suspension rope 400 is wrapped around the rotating structure 100 so that the rotating structure 100 is pressed against the elastic support component 310 and the switch sensing component 320.
[0031] In this embodiment, one end of the suspension rope 400 is connected to the winding device of the lifting lamp, and the other end is connected to the lamp body. The suspension rope 400 is wound around the rotating structure 100. Due to gravity, during the descent of the lifting lamp, the suspension rope 400 drives the rotating structure 100 to rotate. At this time, there is pressure between the suspension rope 400 and the rotating structure 100 due to contact. Simultaneously, since the rotating structure 100 is rotatably connected to the elastic support component 310 and the switch sensing component 320, the rotating structure 100 maintains a force balance under the action of the elastic force of the elastic support component 310 and the supporting force of the switch sensing component 320. Furthermore, during the process of the suspension rope 400 driving the rotating structure 100 to rotate, if the lamp body is obstructed or touches an obstacle, the direction or magnitude of the tension in the suspension rope 400 changes, resulting in a pressure imbalance between the suspension rope 400 and the rotating structure 100. At this time, the elastic element in the elastic support component 310 will release elastic potential energy, pushing the rotating structure 100 to move upward, causing the rotating structure 100 and the switch sensing component 320 to lose their mutual balance force, the stroke of the induction switch in the switch sensing component 320 changes, and then outputs a sensing signal to the main control component of the lifting light to control the lifting light to stop continuing to descend, so as to achieve the effect of anti-collision.
[0032] On the other hand, when the lifting light is in a stationary state, if the light body is subjected to an upward force, the force state of the suspension rope 400 will change, resulting in a pressure imbalance between the suspension rope 400 and the rotating structure 100. Similarly, the stroke of the induction switch in the switch induction component 320 will change, so as to output an induction signal to the main control component of the lifting light, thereby controlling the lifting light to move upward, and thus enabling the lifting light to achieve the effect of retracting the light body by touch.
[0033] The aforementioned anti-collision sensing device 10 utilizes the force change between the suspension rope 400 and the rotating structure 100 as a trigger signal. The elastic support component 310 releases potential energy to drive the switch sensing component 320 to output a sensing signal to the main control component of the lifting lamp, thereby controlling the lamp body. Specifically, if the lamp body is obstructed during descent, the switch sensing component 320 will output a signal to the main control component of the lifting lamp to stop its descent. When the lamp body is stationary, if it is subjected to an upward force, the main control component of the lifting lamp will control the lamp to rise, thus improving the functionality and reliability of the anti-collision sensing device 10.
[0034] like Figure 2 and Figure 3As shown, in one embodiment, the switch sensing component 320 includes a contact sensing switch 321 and a first rotating boss 322. The contact sensing switch 321 is connected to the first rotating boss 322. The elastic support component 310 includes an elastic sensing element 311 and a second rotating boss 312. The elastic sensing element 311 is connected to the second rotating boss 312. The rotating structure 100 is rotatably connected to the first rotating boss 322 and the second rotating boss 312, respectively. In this embodiment, the rotatable connection design between the rotating structure 100 and the first rotating boss 322 and the second rotating boss 312 not only enhances the stability of the overall structure of the device, but also ensures that the rotating structure 100 can rotate flexibly when subjected to force, thereby more accurately transmitting the changes in the force state between the suspension rope 400 and the rotating structure 100. When the lifting light is obstructed from descending or is stationary, it is subjected to an upward force. The rotating structure 100 can respond quickly and convert the force change into an effective action on the contact induction switch 321 and the elastic sensing element 311 through the first rotating boss 322 and the second rotating boss 312, thereby triggering the sensing signal and realizing precise control of the lifting light. This significantly improves the sensitivity and reliability of the anti-collision sensing device 10.
[0035] like Figure 2 and Figure 4 As shown, in one embodiment, the first rotating boss 322 has a third receiving cavity 3201, and the second rotating boss 312 has a fourth receiving cavity 3101. A portion of the contact sensor switch 321 is housed in the third receiving cavity 3201, and another portion is disposed in the first receiving cavity 2201. A portion of the elastic sensing element 311 is housed in the fourth receiving cavity 3101, and another portion is housed in the second receiving cavity 2301. In this embodiment, the contact sensor switch 321, by being partially housed in the third receiving cavity 3201, achieves a stable connection with the first rotating boss 322. Simultaneously, the portion of the contact sensor switch 321 within the first receiving cavity 2201 can more directly sense the force changes transmitted from the rotating structure 100, ensuring timely and accurate output of the sensing signal. The partial housing of the elastic sensing element 311 in the fourth receiving cavity 3101 and the second receiving cavity 2301 enhances the stability of the elastic sensing element 311 and provides it with sufficient elastic deformation space. When the pressure between the suspension rope 400 and the rotating structure 100 is unbalanced, the elastic sensing element 311 can quickly release elastic potential energy, pushing the rotating structure 100 to move upward, thereby triggering the contact induction switch 321 to output a sensing signal, thereby improving the response speed and sensitivity of the anti-collision sensing device 10, ensuring that the lifting light can react quickly when it is obstructed in its descent or when it is stationary and subjected to an upward force, achieving precise control, and further improving the functionality and reliability of the device.
[0036] like Figure 3As shown, in one embodiment, the first rotating boss 322 is further provided with a first concave through groove 3202, and the second rotating boss 312 is further provided with a second concave through groove 3102. The rotating structure 100 is rotatably connected to the first concave through groove 3202 and the second concave through groove 3102 respectively. In this embodiment, the first concave through groove 3202 and the second concave through groove 3102 provide a precise rotation track for the rotating structure 100, enabling the rotating structure 100 to rotate smoothly along a predetermined path when subjected to force, effectively reducing errors and malfunctions caused by rotational deviation, and making the interaction between the rotating structure 100, the contact sensor switch 321, and the elastic sensor 311 more accurate. When the pressure between the suspension rope 400 and the rotating structure 100 changes, the rotating structure 100 can remain rotating within the first concave through groove 3202 and the second concave through groove 3102, accurately transmitting the force change to the contact sensor switch 321 and the elastic sensor 311, thereby quickly triggering the output of the sensing signal.
[0037] like Figure 2 and Figure 5 As shown, in one embodiment, the base structure 200 further includes a limiting post 240. One end of the limiting post 240 is connected to the second support base 230, and the limiting post 240 is fixed within the second receiving cavity 2301. The other end of the limiting post 240 is housed within the elastic sensing element 311. In this embodiment, the limiting post 240 provides effective support and positioning for the elastic sensing element 311. When the elastic sensing element 311 undergoes elastic deformation due to force changes between the suspension rope 400 and the rotating structure 100, the limiting post 240 can limit excessive deformation of the elastic sensing element 311, preventing damage due to excessive compression or stretching, thereby extending the service life of the elastic sensing element 311. Simultaneously, the fixing effect of the limiting post 240 also ensures the stable position of the elastic sensing element 311 within the second receiving cavity 2301, avoiding inaccurate sensing signals caused by the offset or shaking of the elastic sensing element 311.
[0038] like Figure 2 and Figure 3As shown, in one embodiment, the limiting base 210 has a transmission receiving groove 2103, and the rotating structure 100 includes a suspension drive wheel 110 and a winding drive shaft 120. The suspension drive wheel 110 has a transmission through hole 1101 and is disposed in the transmission receiving groove 2103. The winding drive shaft 120 passes through the first rotation through hole 2101, the transmission through hole 1101 and the second rotation through hole 2102 respectively. In this embodiment, the sidewall of the transmission receiving groove 2103 effectively limits the suspension drive wheel 110, preventing it from shifting or shaking during rotation. The winding drive shaft 120 passes through the first rotation through hole 2101, the transmission through hole 1101, and the second rotation through hole 2102, respectively, so that the winding drive shaft 120 forms a tight connection with the limiting base 210 and the suspension drive wheel 110, ensuring the smoothness of the winding drive shaft 120 during rotation and reducing wear and malfunctions caused by poor rotation.
[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the limiting base 210 also has a circular through hole 2104 for the suspension wire, and the suspension wire drive wheel 110 has an annular groove 1102. The suspension rope 400 is wound in the annular groove 1102, with one end of the suspension rope 400 passing through the circular through hole 2104 and the other end used to connect to the winding device of the lifting lamp. In this embodiment, the suspension rope 400 passes through the circular through hole 2104 and is wound in the annular groove 1102 of the suspension wire drive wheel 110, so that the suspension rope 400 can stably transmit power during the lifting of the lamp. When the winding device retracts or releases the suspension rope 400, the suspension rope 400 can be wound or released in an orderly manner along the annular groove 1102, ensuring that the lifting lamp can be lifted and lowered according to the predetermined speed and direction, thus achieving precise control of the lifting lamp. During the descent of the lifting lamp, if the lamp body is obstructed or touches an obstacle, the pressure between the suspension rope 400 and the suspension wire drive wheel 110 will change. Since one end of the suspension rope 400 is fixed to the winding device, and the other end is connected to the lamp body and wound around the suspension drive wheel 110, this change in force can be quickly transmitted through the suspension rope 400 to the suspension drive wheel 110 and the winding drive shaft 120, thereby triggering the action of the elastic support component 310 and the switch sensing component 320, stopping the lamp from descending and achieving the anti-collision function. Similarly, when the lamp is in a stationary state, if the lamp body is subjected to an upward force, the force state of the suspension rope 400 changes, which can also quickly trigger the sensing signal to control the lamp to move upward, achieving the lamp body retraction effect.
[0040] like Figure 3 and Figure 5As shown, in one embodiment, the winding drive shaft 120 has a first annular boss 121 and a second annular boss 122. The first annular boss 121 is disposed on the outer side of the elastic support assembly 310, and the second annular boss 122 is disposed on the outer side of the switch sensing assembly 320. In this embodiment, the first annular boss 121 is located on the outer side of the elastic support assembly 310, effectively preventing axial movement of the winding drive shaft 120 under the action of the elastic support assembly 310, and ensuring a tight fit between the elastic support assembly 310 and the winding drive shaft 120. Similarly, the second annular boss 122 is located on the outer side of the switch sensing assembly 320, limiting the axial displacement of the winding drive shaft 120 under the action of the elastic support assembly 310, and ensuring that the switch sensing assembly 320 can accurately sense the rotational state of the winding drive shaft 120. During the descent or ascent of the lifting light, the force change between the suspension rope 400 and the suspension drive wheel 110 is rapidly transmitted to the winding drive shaft 120. This allows the first annular boss 121 and the second annular boss 122 to more accurately transmit force changes to the elastic support component 310 and the switch sensing component 320.
[0041] like Figure 4 As shown, in one embodiment, the anti-collision sensing device 10 further includes a positioning structure 500, which includes a pulley assembly 510 and a pulley base 520. The pulley assembly 510 is rotatably connected to the pulley base 520 and is used to slide the suspension rope 400. In this embodiment, during the lifting and lowering of the light, the suspension rope 400, guided by the pulley assembly 510, can more smoothly change its transmission direction, avoiding friction and entanglement between the suspension rope 400 and other components, reducing wear on the suspension rope 400, and improving the transmission efficiency of the suspension rope 400. The rotatable connection between the pulley assembly 510 and the pulley base 520 makes the entire device more stable during operation. When the suspension rope 400 slides on the pulley assembly 510, the pulley assembly 510 can rotate flexibly with the movement of the suspension rope 400, reducing the swaying and impact caused by changes in the tension of the suspension rope 400, enhancing the overall structural stability of the device, and reducing the risk of failure caused by vibration or swaying.
[0042] This application also provides an electric lifting light, including an anti-collision sensing device 10 according to any embodiment. In this embodiment, one end of the suspension rope 400 is connected to the winding device of the lifting light, and the other end is connected to the lamp body of the lifting light. The suspension rope 400 is wound around the rotating structure 100. Due to gravity, during the descent of the lifting light, the suspension rope 400 drives the rotating structure 100 to rotate. At this time, there is pressure between the suspension rope 400 and the rotating structure 100 due to contact. At the same time, since the rotating structure 100 is rotatably connected to the elastic support component 310 and the switch sensing component 320 respectively, the rotating structure 100 maintains a force balance under the action of the elastic force of the elastic support component 310 and the supporting force of the switch sensing component 320. Further, during the process of the suspension rope 400 driving the rotating structure 100 to rotate, if the lamp body of the lifting light is blocked or touches an obstacle, the direction or magnitude of the tension at the other end of the suspension rope 400 changes, resulting in a pressure imbalance between the suspension rope 400 and the rotating structure 100. At this time, the elastic element in the elastic support component 310 will release its elastic potential energy, pushing the rotating structure 100 upward. This causes the rotating structure 100 and the switch sensing component 320 to lose their mutual balance force, and the stroke of the inductive switch in the switch sensing component 320 changes. Consequently, it outputs a sensing signal to the main control component of the lifting lamp to control the lifting lamp to stop descending, achieving an anti-collision effect. On the other hand, when the lifting lamp is in a stationary state, if the lamp body is subjected to an upward force, the force state of the suspension rope 400 will change, causing an imbalance in pressure between the suspension rope 400 and the rotating structure 100. Similarly, the stroke of the inductive switch in the switch sensing component 320 changes, outputting a sensing signal to the main control component of the lifting lamp, thereby controlling the lifting lamp to move upward. This allows the lifting lamp to retract by touch.
[0043] Compared with the prior art, this disclosure has at least the following advantages:
[0044] The aforementioned anti-collision sensing device 10 utilizes the force change between the suspension rope 400 and the rotating structure 100 as a trigger signal. The elastic support component 310 releases potential energy to drive the switch sensing component 320 to output a sensing signal to the main control component of the lifting lamp, thereby controlling the lamp body. Specifically, if the lamp body is obstructed during descent, the switch sensing component 320 will output a signal to the main control component of the lifting lamp to stop its descent. When the lamp body is stationary, if it is subjected to an upward force, the main control component of the lifting lamp will control the lamp to rise, thus improving the functionality and reliability of the anti-collision sensing device 10.
[0045] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
