Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts, and in particular to a lifting device for a deflector. Background Technology
[0002] Motorcycle windshields effectively block airflow and protect against debris, creating a comfortable and safe riding environment for riders. Adjustable height windshields have become the mainstream configuration due to their suitability for riders of different heights and various riding scenarios.
[0003] In existing solutions, the windshield lifting device's transmission system utilizes two ropes of significantly different lengths (e.g., a difference of three times or more) to form a closed-loop transmission chain, driving two sliders fixedly connected to the windshield along a guide rail. Because the longer rope has a much higher friction frequency and bending frequency than the shorter rope, its wear and stretching speeds are much faster, quickly disrupting the initial tension balance and length matching of the system. This leads to decreased synchronization accuracy of the two sliders and windshield malfunction. Furthermore, the clearance reserved to ensure smooth sliding of the sliders within the guide rail prevents the windshield and sliders, which are continuously subjected to airflow impacts during riding, from being stably restrained, resulting in windshield vibration and abnormal noises caused by impacts. These windshield malfunctions, vibrations, and abnormal noises from impacts all severely impact the riding experience. Summary of the Invention
[0004] This application provides a lifting device for a deflector, which aims to solve the problems of synchronization failure caused by uneven rope wear and vibration and abnormal noise caused by the gap between the slider and the guide rail in existing lifting devices, so as to improve the user's riding experience.
[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is: This application discloses a lifting device for a flow deflector, comprising: Support base; Two movable components are disposed on the support base. Each movable component includes a guide rail for supporting the movable member of the flow deflector. The two movable components are arranged along a first direction, which is perpendicular to the moving direction of the movable components. The two movable components are a first movable component and a second movable component. The first movable component has a first end and a second end along a second direction, and the second movable component has a third end and a fourth end along the second direction. The first end and the third end are located on the same side, and the second end and the fourth end are located on the same side. The second direction is parallel to the moving direction of the movable components. The guide rail has a strip-shaped through hole and a strip-shaped channel communicating with the strip-shaped through hole; the movable component is movably mounted on the guide rail; the movable component has a component body, a deformable abutment, and a deformable support, at least a portion of the component body is located within the strip-shaped channel, the deformable abutment is located within the strip-shaped channel and at least a portion is connected to the component body, both the deformable abutment and the deformable support are capable of elastic deformation, the deformable support acts on the deformable abutment so that a portion of the surface of the deformable abutment abuts against the guide wall of the strip-shaped channel; A drive assembly includes a drive reel, a first rope, a second rope, and a third rope. The drive reel is rotatably mounted on the support base. The two ends of the first rope are connected to the drive reel and the first end, respectively. The two ends of the second rope are connected to the second end and the third end, respectively. The two ends of the third rope are connected to the fourth end and the drive reel, respectively, so that the first moving member and the second moving member move synchronously.
[0006] This application combines elastic self-compensating guidance with three-rope balanced transmission to achieve smooth, quiet lifting and lowering of the flow deflector, significantly improving motion stability, reliability and user experience.
[0007] Specifically, this application utilizes three ropes to form a closed-loop rope transmission chain, making the lengths of the ropes more similar, making the friction frequency and bending number of each rope more similar, reducing rope wear and stretching speed, extending the service life of the ropes, and enabling the two moving components to maintain synchronous movement for a long time. At the same time, the main body of the component directly abuts against the guide wall of the strip channel to form a basic guide limit. Meanwhile, the deformation support drives the deformation abutment to elastically fit against the guide wall, compensating for the fit gap between the main body of the component and the guide rail, effectively resisting the impact load of the fluid on the flow baffle, avoiding the flow baffle from shaking and abnormal noise caused by shaking and collision, and ensuring that the flow baffle remains stable.
[0008] In some embodiments, the moving component further includes two fixed pulleys, which are respectively disposed on both sides of the guide rail along the second direction. The first rope, the second rope, and the third rope are respectively wrapped around the outside of the corresponding fixed pulleys and connected to the moving component.
[0009] In some embodiments, the drive reel has a first cavity on one side of its axial direction and a second cavity on the other side of its axial direction; the drive reel has a helical groove on its radial circumference; both the first cavity and the second cavity are in communication with the helical groove; the end of the first rope is engaged in the first cavity and wound around the helical groove; the end of the third rope is engaged in the second cavity and wound around the helical groove.
[0010] In some embodiments, the second rope has a flexible section and a tension section, with the tension section connected to both ends of the flexible section. The tension section is used to connect to the moving member, and the tension section is connected to the moving member. The lifting device for the flow deflector includes a sleeve and an intermediate component. The sleeve covers the flexible section, and the intermediate component is connected to both ends of the sleeve. The intermediate component has a threading channel for the second rope to pass through. The outer side of the intermediate component is connected to the support base, and the connection position between at least one of the intermediate components and the support base is adjustable.
[0011] In some embodiments, the support base has two protrusions on the side facing the second rope, and the two protrusions are respectively connected to the two intermediate members.
[0012] In some embodiments, at least one of the intermediate members is threadedly connected to the protrusion.
[0013] In some embodiments, at least one of the intermediate members has an external threaded connection section and an operating force-applying section, wherein the external threaded connection section forms a threaded engagement with the protrusion. The lifting device for the flow deflector also includes a locking member, which is threadedly connected to the external threaded connection section and located between the operating force section and the protrusion to lock the intermediate component.
[0014] In some embodiments, the lifting device for the flow deflector further includes a locking member, which is threadedly connected to the external threaded connection section and located between the operating force section and the protrusion to lock the intermediate member.
[0015] In some embodiments, the bottom of the movable member has a receiving cavity located on the side where the movable member is connected to the first rope or on the side where the movable member is connected to the third rope. A spring is disposed in the receiving cavity, with one axial end of the spring abutting against the wall of the receiving cavity and the other axial end abutting against the head of the first rope or the other axial end abutting against the head of the third rope. The spring is in a pre-compressed state within the receiving cavity.
[0016] In some embodiments, the deformable abutment includes a first cantilever, the deformable support contacting the free end of the first cantilever such that the free end of the first cantilever elastically abuts against the strip channel; The deformable support is located within the strip channel, and the deformable support includes a second cantilever, the free end of which contacts the free end of the first cantilever.
[0017] The beneficial effects of this application are as follows: Compared with existing technologies, this application achieves synchronous movement of two moving components through innovative three-rope linkage, enabling precise adjustment of the pre-installation position of the moving components. This effectively solves the technical pain points of asynchronous movement and offset jamming of moving components that are prone to occur in existing dual-drive or multi-drive transmission structures, and improves the transmission stability and operational reliability of the lifting device used for flow deflectors.
[0018] Specifically, this application connects the two sides of the drive reel axially to a set of opposite ends of the two moving components via a first rope and a third rope, respectively, and the second rope connects to another set of opposite ends of the two moving components, forming a closed-loop rope transmission chain. The rotational power of the drive reel is synchronously transmitted to the two sets of opposite ends of the moving components via the three ropes, and tension or thrust is applied to the moving components from the two sets of opposite ends, constraining the two moving components to move synchronously and in the same direction along the first direction.

[0025] Combination Figures 1 to 8 As shown, this application discloses a lifting device for a flow deflector, comprising: Support base 100; Two movable components 200 are disposed on the support base 100. Each movable component 200 includes a movable member 210 for supporting a flow deflector. The two movable members 210 are arranged along a first direction, which is perpendicular to the direction of movement of the movable members 210. The two movable members 210 are a first movable member 210A and a second movable member 210B. The first movable member 210A has a first end 210A1 and a second end 210A2 along a second direction. The second movable member 210B has a third end 210B1 and a fourth end 210B2 along the second direction. The first end 210A1 and the third end 210B1 are located on the same side, and the second end 210A2 and the fourth end 210B2 are located on the same side. The second direction is parallel to the direction of movement of the movable members 210. A drive assembly 300 includes a drive reel 310, a first rope 320, a second rope 330, and a third rope 340. The drive reel 310 is rotatably mounted on the support base 100. The two ends of the first rope 320 are connected to the drive reel 310 and the first end 210A1, respectively. The two ends of the second rope 330 are connected to the second end 210A2 and the third end 210B1, respectively. The two ends of the third rope 340 are connected to the fourth end 210B2 and the drive reel 310, respectively, so that the first moving member 210A and the second moving member 210B move synchronously.
[0026] This application utilizes three ropes to form a closed-loop rope transmission chain, making the rope lengths more similar and the friction frequency and bending number of each rope more similar. This reduces rope wear and tension, extends rope life, and allows the two moving components 210 to maintain synchronized movement over a long period. Specifically, the drive pulley 310 is connected to the first end 210A1 of the first moving component 210A and the fourth end 210B2 of the second moving component 210B via the first rope 320 and the third rope 340, respectively. The second rope 330 spans the second end 210A2 of the first moving component 210A and the third end 210B1 of the second moving component 210B, forming a closed-loop rope transmission chain. The rotational power of the drive pulley 310 is synchronously transmitted to the two moving components 210 through the three ropes, causing the two moving components 210 to move synchronously in the same direction along the first direction. This avoids the problem of asynchronous movement of the moving components 210 and effectively improves the stability and reliability of the flow deflector movement.
[0027] The lifting device for the deflector in this application can be applied to motorcycles and speedboats for wind and water blocking. The deflector can be a transparent glass plate or an acrylic plate.
[0028] Combination Figure 1 , Figure 2 , Figure 3 as well as Figure 6 As shown, in some embodiments, the moving component 200 includes a guide rail 220, two pulley frames 240, and two fixed pulleys 230. The guide rail 220 is fixedly mounted on the support base 100 and extends along a second direction. The moving component 210 is movably mounted on the guide rail 220. The two pulley frames 240 are respectively fixedly mounted on opposite sides of the guide rail 220 along the second direction. The two fixed pulleys 230 are rotatably connected to the two pulley frames 240 in a one-to-one correspondence. The fixed pulley 230 acts as a fulcrum, guiding the first, second, and third ropes 340 and changing the tangential direction of the ropes. This allows the ropes to adjust their entry and exit directions to a suitable angle after passing through the fixed pulley 230, for example, adjusting them to be parallel to the guide rail 220. This reduces or avoids lateral force components caused by the tilting of the tension or thrust direction, effectively improving force transmission efficiency.
[0029] Furthermore, the first rope 320 rubs against the fixed pulley 230 and the drive reel 310, the second rope 330 rubs against the two fixed pulleys 230, and the third rope 340 rubs against the fixed pulley 230 and the drive reel 310. All three ropes rub against two parts, and the friction frequencies are close or the same.
[0030] Furthermore, the insertion part 241 is inserted into the guide rail 220, the pulley mounting part 242 abuts against the outer end face of the guide rail 220 along the second direction, and the fixed pulley 230 is mounted on the pulley mounting part 242.
[0031] The insertion part 241 of the pulley frame 240 is inserted into the guide rail 220, which allows for quick positioning of the pulley frame 240 in the first direction during installation; the pulley mounting part 242 of the pulley frame 240 abuts against the end face of the guide rail 220, which allows for quick positioning of the pulley frame 240 in the second direction during installation. This structure naturally forms a double limit along the first and second directions during installation, eliminating the need for repeated manual adjustments to the fixed position of the pulley frame 240, thus improving installation efficiency.
[0032] Furthermore, when the moving member 210 moves to its limit position, the moving member 210 abuts against the insertion part 241.
[0033] The insertion part 241 of the pulley frame 240 is configured as a limit stop for the movement of the moving member 210 along the second direction, based on the insertion and positioning with the guide rail 220. When the moving member 210 moves to the preset limit position along the extension direction of the guide rail 220 (i.e. the second direction), the end face of the moving member 210 and the limiting end face of the insertion part 241 form a rigid abutment fit, eliminating the need for additional limiting blocks and simplifying the overall structure of the moving component 200.
[0034] Furthermore, the movable member 210 has a release groove 215 and a thickened portion 216 on at least one side along the second direction. The release groove 215 is used for demolding the top block of the mold, and the thickened portion 216 is located outside the release groove 215.
[0035] The movable component 210 of this application is a metal casting or injection molded part. The design of the ejection groove 215 facilitates the ejection of the movable component 210 by the mold's top block. However, the design of the ejection groove 215 will reduce the local wall thickness near the ejection groove 215 accordingly. When the top block detaches from the ejection groove 215, if the material structure near the ejection groove 215 is thin, it will cause the ejection groove 215 and the structure near the ejection groove 215 to deform and break, resulting in a defective product. Therefore, a thickened part 216 is added to the outside of the ejection groove 215 to increase the wall thickness near the outside of the ejection groove 215. This can compensate for the weakened local strength due to the groove, prevent deformation under stress, and effectively improve the finished product qualification rate and structural reliability of the movable component 210.
[0036] Furthermore, the insertion portion 241 includes a first abutting portion 2411 and a second abutting portion 2412, with a recessed portion 2413 between the first abutting portion 2411 and the second abutting portion 2412. The first abutting portion 2411 and the second abutting portion are used to abut against the moving member 210; the thickened portion 216 can extend into the recessed portion 2413.
[0037] The first abutting part 2411 and the second abutting part 2412 abut against the limiting end faces on both sides of the thickened part 216, respectively, which can simultaneously constrain the extreme position of the moving member 210 on both sides, and prevent the moving member 210 from being deflected by one side when abutting. The cooperation between the thickened part 216 and the recessed part 2413 can achieve spatial avoidance of the thickened part 216 while limiting abutting, avoiding collision between the thickened part 216 and the insertion part 241, and avoiding the thickened part 216 bearing the impact independently. In this way, the main impact load is more evenly distributed to the limiting end faces and abutting parts on both sides. The impact force is distributed to two contact areas, avoiding a single point bearing all the impact, significantly reducing local stress, and improving the stability of the limiting action and the service life of the structure.
[0038] Combination Figure 1 , Figure 2 as well as Figure 6 As shown, at least one side of the pulley mounting portion 242 has staggered ribs 243. The staggered ribs 243 can improve the bending and torsional stiffness of the pulley mounting portion 242, distribute the radial load transmitted when the fixed pulley 230 rotates, and prevent the pulley mounting portion 242 from bending and deforming due to long-term stress.
[0039] Furthermore, the pulley mounting portion 242 is provided with a weight-reducing groove 244. The weight-reducing groove 244 can effectively reduce the amount of material used in the pulley mounting portion 242, reduce the overall weight of the pulley frame 240, thereby reducing the load on the guide rail 220 and the support base 100, and optimizing the overall weight distribution of the lifting device used for the flow deflector.
[0040] Combination Figure 1 and Figure 2 As shown, in some embodiments, the second rope 330 has a flexible section 331 and a tensioning section 332. The two ends of the flexible section 331 are connected to the tensioning section 332, which is used to connect to the moving member 210. The adjustment structure includes a sleeve 410 and an intermediate member 420. The sleeve 410 covers the flexible section 331, and the two ends of the sleeve 410 are respectively connected to the intermediate member 420. The intermediate member 420 has a threading channel for the second rope 330 to pass through. The outer side of the intermediate member 420 is connected to the support base 100, and the connection position between at least one intermediate member 420 and the support base 100 is adjustable. The intermediate member 420 serves as the connection medium between the sleeve 410 and the support base 100. When adjusting the position of the sleeve 410, only the position-adjustable intermediate member 420 needs to be operated to drive the sleeve 410, the flexible section 331, and the tensioning section 332 to move, ultimately adjusting the moving member 210 to the pre-installation position.
[0041] Specifically, by adjusting the position of the sleeve 410, the degree of bending constraint of the sleeve 410 on the flexible section 331 can be adjusted, which can indirectly drive the moving component 210 connected to the tensioning section 332 to move, thereby achieving the purpose of adjusting the position of the moving component 210, and finally aligning the two moving components 210 along the first direction.
[0042] In some embodiments, the support base 100 has two protrusions 110 on the side facing the second rope 330, and the two protrusions 110 are respectively connected to two intermediate members 420. The protrusions 110 provide a stable mounting reference for the intermediate members 420, and the protrusions 110 can lift the connection point of the intermediate members 420 from the main structural surface of the support base 100, effectively reducing the scraping, friction or interference between the second rope 330 and the main structural surface of the support base 100, effectively extending the service life of the second rope 330, and reducing noise caused by friction.
[0043] Optionally, depending on actual needs, the intermediate component 420 and the protrusion 110 can be connected by snap-fit, threaded connection, or other methods.
[0044] The protrusion 110 can be a lug, boss, column or other protruding structure that protrudes from the support base 100, and is not specifically limited here.
[0045] In some embodiments, at least one intermediate member 420 is threadedly connected to the protrusion 110; by rotating the intermediate member 420, it moves along the thread axis of the protrusion 110, thereby changing the connection position of one end of the sleeve 410, thereby adjusting the position of the moving member 210.
[0046] Specifically, at least one of the intermediate components 420 has an external threaded connection section 421 and an operating force-applying section 422, wherein the external threaded connection section 421 is threadedly engaged with the protrusion 110. The operating force-applying section 422 is used by installers and maintenance personnel to apply force and rotate the component using tools (such as wrenches, sockets, etc.).
[0047] Optionally, the operating force-applying section 422 can be any of the following structures: hexagonal head, internal hexagonal hole, slotted slot, Phillips head, or external square head. In this embodiment, the operating force-applying section 422 is a hexagonal head structure.
[0048] The adjustment structure also includes a locking member 430, which is threadedly connected to the external threaded connection section 421 and located between the operating force application section 422 and the protrusion 110 to lock the intermediate member 420. When the intermediate member 420 is threadedly engaged with the protrusion 110 and adjusted to the desired position, tightening the locking member 430 presses it against the end face of the protrusion 110, thereby firmly locking the position of the intermediate member 420 and effectively preventing accidental rotation of the intermediate member 420.
[0049] Optionally, the locking element 430 is a hexagonal nut. Installers and maintenance personnel can use a wrench to apply force to rotate the hexagonal nut to tighten or loosen it.
[0050] In other embodiments, the protrusion 110 is provided with an adjusting elongated hole extending along a first direction. An intermediate member 420 passes through the adjusting elongated hole and has a threaded channel through which a second rope 330 passes. The outer surface of the intermediate member 420 is only provided with an externally threaded connecting section 421. Two locking nuts are threadedly connected to the intermediate member 420, and the two locking nuts are respectively located on both sides of the intermediate member 420 along its length direction to fix the intermediate member 420. Adjusting the position of the intermediate member 420 within the adjusting elongated hole can also achieve the purpose of adjusting the position of the flexible section 331.
[0051] Combination Figure 1 and Figure 2 As shown, in some embodiments, a receiving cavity 214 is provided on the side of the moving member 210 connected to the first rope 320 and the third rope 340. A spring member 250 is provided in the receiving cavity 214. One axial end of the spring member 250 abuts against the wall of the receiving cavity 214, and the other axial end abuts against the head of the first rope 320 or the third rope 340. The spring member 250 is in a pre-compressed state in the receiving cavity 214. In this application, when the two moving components 210 are in their limit states, if the state of the first rope 320 is opposite to that of the third rope 340, for example, when the two components are in their descending limit state, the drive reel 310 winds the first rope 320, tightening it, and the drive reel 310 loosens the third rope 340, making it slack. The spring 250 exerts opposing forces on the first rope 320 and the third rope 340. For example, when the drive reel 310 exerts an upward tension force on the first rope 320, the spring 250 exerts a downward tension force on the first rope 320; when the drive reel 310 exerts a downward loosening force on the third rope 340, the spring 250 exerts an upward pushing force on the third rope 340. Therefore, the spring 250 ensures that the first rope 320 and the third rope 340 are in a good tension state when they are in their ascending or descending limit states, effectively guaranteeing the stability of the lifting device used for the flow deflector.
[0052] Optionally, the spring element 250 is a compression spring.
[0053] Combination Figure 1 , Figure 2 , Figure 7 as well as Figure 8 As shown, in some embodiments, the drive reel 310 has a first cavity 311A on one axial side and a second cavity 311B on the other axial side. The drive reel 310 has a spiral groove 312 on its radial circumferential side. The first cavity 311A and the second cavity 311B are both connected to the spiral groove 312. The ends of the first rope 320 and the third rope 340 are independently secured in the first cavity 311A and the second cavity 311B on opposite sides of the drive reel 310, and are wound in an orderly manner along the spiral groove 312 on the circumference of the reel. Compared with the existing screw-pressing fixing structure, installation can be completed simply by placing the ends of the ropes into the corresponding cavities, making the assembly and disassembly operations simple and efficient; the two ropes can be synchronously wound and unwound by rotating a single drive reel 310, resulting in good consistency in displacement during winding and unwinding.
[0054] Furthermore, the drive roller 310 also includes a first blocking portion 317A, which at least partially blocks the first cavity 311A.
[0055] The first shielding part 317A forms a physical limit on the end of the first rope 320 that is locked in the first cavity 311A from the outside, effectively preventing the first rope 320 from accidentally coming out of the first cavity 311A during vibration, impact or repeated winding and unwinding, thereby improving the working stability of the entire transmission system.
[0056] Furthermore, the drive roller 310 also includes a second blocking portion 317B, which at least partially blocks the second cavity 311B.
[0057] The second shielding part 317B physically limits the end of the third rope 340, which is locked in the second cavity 311B, from the outside, effectively preventing the third rope 340 from accidentally disengaging from the second cavity 311B during vibration, impact, or repeated winding and unwinding, thereby improving the working stability of the entire transmission system.
[0058] In other embodiments, the ends of the first rope 320 and the third rope 340 can be connected to the first cavity 311A and the second cavity 311B by a snap-fit structure. Similarly, the end of the first rope 320 can be snapped into the first cavity 311A and the end of the third rope 340 can be snapped into the third cavity.
[0059] Furthermore, the drive roller 310 has a first arc-shaped transition groove 313A, one end of which is connected in communication with the first cavity 311A, and the other end is connected in communication with the spiral groove 312.
[0060] The first arc-shaped transition groove 313A can eliminate the sharp corner structure at the junction of the first concave cavity 311A and the spiral groove 312, avoid stress concentration caused by excessive bending angle during the retraction and retraction of the first rope 320, effectively alleviate fatigue damage caused by bending of the first rope 320, thereby reducing the wear rate of the first rope 320 and extending the service life of the first rope 320.
[0061] Furthermore, the drive roller 310 has a second arc-shaped transition groove 313B, one end of which is connected in communication with the second cavity 311B, and the other end is connected in communication with the spiral groove 312.
[0062] The second arc-shaped transition groove 313B can eliminate the sharp corner structure at the junction of the second concave cavity 311B and the spiral groove 312, and avoid stress concentration caused by excessive bending angle during the retraction and retraction of the third rope 340. This effectively alleviates fatigue damage caused by bending of the third rope 340, thereby reducing the wear rate of the third rope 340 and extending its service life.
[0063] Furthermore, both the first rope 320 and the third rope 340 have a rope body and a locking portion fixed to one end of the rope body. The locking portion is located in the first cavity 311A or the second cavity 311B. The locking portion abuts against the drive reel 310. A portion of the rope body is located in the first arc-shaped transition groove 313A or the second arc-shaped transition groove 313B.
[0064] The locking part and the cavity (first cavity 311A, second cavity 311B) abutting and mating structure do not require additional fasteners (such as bolts, expansion sleeves, etc.). During assembly, the locking part only needs to be inserted into the corresponding cavity to complete the positioning and fixation. The disassembly and assembly operations are simple and efficient. The rope body is guided by the arc-shaped transition groove, so that the reversing process of the rope (first rope 320, third rope 340) from the cavity into the spiral groove 312 forms a smooth transition trajectory, so that the rope is more evenly stressed, alleviates fatigue damage caused by long-term repeated bending, and extends the service life of the rope.
[0065] Furthermore, the drive reel 310 has a first take-out groove 318A, which is connected in communication with the first cavity 311A.
[0066] The first extraction groove 318A is located on the side of the first cavity 311A away from the spiral groove 312. The width of the first extraction groove 318A is smaller than the width of the first cavity 311A and smaller than the width of the locking part.
[0067] Furthermore, the drive reel 310 has a second take-out groove 318B, which is connected in communication with the second cavity 311B.
[0068] The second extraction groove 318B is located on the side of the second cavity 311B away from the spiral groove 312. The width of the second extraction groove 318B is smaller than the width of the second cavity 311B and smaller than the width of the locking part.
[0069] Although the width of the rope's locking part is smaller than the width of the first cavity 311A and the second cavity 311B, it occupies most of the space in the first cavity 311A and the second cavity 311B, leaving very little space for tools to reach into the first cavity 311A and the second cavity 311B to move the rope. Therefore, the setting of the extraction slots (first extraction slot 318A and second extraction slot 318B) provides a tool operation channel for the disassembly of the first rope 320 and the third rope 340. Maintenance personnel do not need to disassemble the entire drive reel 310; they only need to insert the tool laterally into the corresponding cavity through the extraction slot to accurately push the rope's locking part and push it obliquely upwards towards the extraction slot, so that the locking part can be smoothly disengaged from the cavity. Then, maintenance personnel can directly pull out the rope by grasping the locking part of the rope to complete the disassembly.
[0070] Because the width of the extraction slot is smaller than the width of the locking part, the locking part is always confined inside the cavity under the tension of the rope during normal winding and unwinding, and cannot be released through the extraction slot.
[0071] Furthermore, the end face of the drive reel 310 is provided with a plurality of circumferentially distributed recesses 319. The recesses 319 are used to store lubricating grease. Under the operation of the drive reel 310, the centrifugal force and the increase in temperature will cause the grease stored in the recesses 319 to slowly precipitate out and flow to the spiral groove 312 to lubricate the first rope 320 and the third rope 340, reduce rope wear and corrosion, and effectively extend the service life of the lifting device used for the flow deflector.
[0072] Furthermore, the first cavity 311A and the second cavity 311B are axially opposite and connected, forming a through groove. Machining a single through groove is simpler than machining two independent cavities that require precise alignment. The through groove structure allows for direct forming through a single continuous machining operation (such as drilling, boring, broaching, or wire cutting), which reduces the multiple clamping, tool setting, and tool changing steps required for machining independent double cavities, significantly shortening the machining cycle time of a single part and significantly improving production efficiency.
[0073] Furthermore, the drive reel 310 is fitted with a gear, and the drive assembly 300 also includes a drive motor 350, which is driven by the gear, and the gear is driven by the drive reel 310. By utilizing the axial width of the drive reel 310 to embed the gear, the axial space occupied is reduced, making it easier to adapt to the installation requirements of miniaturized and integrated equipment.
[0074] Furthermore, the drive reel 310 has a spline groove 314 adapted to the gear, and a guide portion 315 is connected to the outer side of the spline groove 314. By providing the spline groove 314 adapted to the gear, a multi-tooth meshing connection is formed between the drive reel 310 and the gear, effectively ensuring the torque transmission capability; the guide portion 315 allows the gear to be easily installed into the spline groove 314, facilitating assembly.
[0075] Furthermore, the guide portion 315 has guide grooves 3151 corresponding one-to-one with the spline grooves 314. Each guide groove 3151 has a first inclined surface 316A, a second inclined surface 316B, and an arc-shaped connecting surface 316C located between the first inclined surface 316A and the second inclined surface 316B. The guide grooves 3151 are arranged with a lower inner surface and a higher outer surface. This structure allows the gear spline teeth to be guided first by the arc-shaped connecting surface 316C when inserted into the spline groove 314, then transition to the first inclined surface 316A and the second inclined surface 316B, and finally to the accurate meshing position. This provides a guiding path from wide to narrow and from shallow to deep, reducing assembly difficulty.
[0076] Combination Figures 3 to 6 As shown, in some embodiments, the guide rail 220 has a strip-shaped through hole 221 and a strip-shaped channel 222 communicating with the strip-shaped through hole 221; The movable component 210 is movably mounted on the guide rail 220; the movable component 210 has a component body 211, a deformable abutment 212, and a deformable support 213. At least a portion of the component body 211 is located within the strip channel 222. The deformable abutment 212 is located within the strip channel 222 and is at least partially connected to the component body 211. Both the deformable abutment 212 and the deformable support 213 are capable of elastic deformation. The deformable support 213 acts on the deformable abutment 212 so that a portion of the surface of the deformable abutment 212 abuts against the guide wall of the strip channel 222.
[0077] This application establishes a basic guide limit by having the main body 211 of the component directly abut against the guide wall of the strip channel 222. At the same time, the deformable support 213 drives the deformable abutment 212 to elastically fit against the guide wall, compensating for the fit gap between the main body 211 of the component and the guide rail 220. This effectively resists the impact load of the fluid on the deflector, avoids the deflector from shaking and abnormal noise caused by shaking and collision, and ensures that the deflector remains stable, thus improving the riding experience.
[0078] Furthermore, the deformable abutment 212 includes a first cantilever 2121, and the deformable support 213 contacts the free end of the first cantilever 2121, causing the free end of the first cantilever 2121 to elastically abut against the strip channel 222. The deformable support 213 provides a deformable elastic force to the free end of the first cantilever 2121, driving the free end of the first cantilever 2121 to elastically deform towards the guide wall, so that the free end of the first cantilever 2121 maintains elastic contact with the strip channel 222.
[0079] The first cantilever 2121 has an abutment portion 2122 and a support portion 2123. The abutment portion 2122 is the free end of the first cantilever 2121, and the support portion 2123 is the connecting end of the first cantilever 2121.
[0080] The support portion 2123 is connected to the main body 211 of the component, and the abutment portion 2122 is connected to the support portion 2123. The deformable support body 213 drives the abutment portion 2122 to deform towards the guide wall surface, so that the abutment portion 2122 remains abutting against the guide wall surface of the strip channel 222. The support portion 2123 serves as the connection between the deformable abutment portion 212 and the main body 211 of the component. Under the drive of the deformable support body 213, the abutment portion 2122 maintains stable contact with the guide wall surface. The abutment portion 2122 and the guide avoid elastic contact, compensating for the fit gap between the main body 211 of the component and the guide rail 220, and preventing the flow deflector from shaking during lifting and use, and preventing abnormal noise caused by shaking and collision.
[0081] Furthermore, the first cantilever 2121 is configured as a T-shaped cantilever, that is, it has free ends connected to both sides of the connecting end, which can realize that the double-sided abutment 2122 can simultaneously and elastically fit with the guide wall surface, avoiding the force offset problem caused by single-sided abutment, making the moving component 210 more evenly stressed, further preventing the flow deflector from shaking, swaying, or jamming, and effectively improving the stability of the flow deflector operation.
[0082] Furthermore, the deformable support 213 is located within the strip channel 222. The deformable support 213 includes a second cantilever 2131, the free end of which contacts the free end of the first cantilever 2121. The free end of the second cantilever 2131 provides a deformation elastic force to the free end of the first cantilever 2121, driving the free end of the first cantilever 2121 to elastically deform towards the guide wall, so that the free end of the first cantilever 2121 maintains elastic contact with the guide wall.
[0083] The second cantilever 2131 has a fixed part 2132 and an elastic deformation part 2133. The fixed part 2132 is the connecting end of the second cantilever 2131, and the elastic deformation part 2133 is the elastic deformation part of the second cantilever 2131.
[0084] The fixing part 2132 is connected to the supporting part 2123. The elastic deformation part 2133 is located on the side of the abutment part 2122 away from the guide wall and exerts a deformation force on the abutment part 2122 towards the guide wall, so that the abutment part 2122 remains abutted against the guide wall. The fixing part 2132 and the supporting part 2123 are firmly connected, responsible for connection and positioning, and provide a reliable installation and force support foundation for the elastic deformation part 2133. The elastic deformation part 2133, relying on its own elastic deformation capability, is responsible for providing deformation force to the abutment part 2122, so that the abutment part 2122 remains abutted against the guide wall.
[0085] Furthermore, the main body 211 of the component has a locking step portion 2111; in the assembled state, the free end of the second cantilever 2131 abuts against the locking step portion 2111 to form a limiting fit.
[0086] During assembly, after the fixing part 2132 is connected to the support part 2123, the free end of the second cantilever 2131 is pushed until it abuts against the locking step part 2111, thereby limiting the maximum deformation of the free end of the second cantilever 2131. The limitation of the maximum deformation directly corresponds to the initial preload threshold of the elastic deformation part 2133, ensuring that the preload output of each set of deformation supports 213 maintains a uniform standard, avoiding excessive friction and wear between the abutment part 2122 and the guide wall due to excessive preload, or failure of clearance compensation and vibration of the flow deflector due to insufficient preload; it can improve the performance consistency of the product during mass production and reduce the difficulty of quality control. The elastic deformation part 2133 has a locking section 2134, which is used to abut against the locking step part 2111.
[0087] Furthermore, the connecting end of the second cantilever 2131 is U-shaped to form a mounting groove 2137, and the connecting end of the first cantilever 2121 is at least partially located within the mounting groove 2137 to mount the second cantilever 2131 onto the first cantilever 2121. The upper side of the connecting end of the first cantilever 2121 supports and positions the mounting groove 2137, thereby defining the position of the second cantilever 2131.
[0088] Furthermore, the free end of the second cantilever 2131 has a connected ascending section 2135 and descending section 2136. The ascending section 2135 and the descending section 2136 have an elastic restoring force toward the free end of the first cantilever 2121, so that the free end of the second cantilever 2131 remains stably abutted against the locking step portion 2111.
[0089] The free end of the second cantilever 2131, namely the elastic deformation part 2133, undergoes elastic bending deformation as a whole, forming an ascending section 2135 and a descending section 2136; after assembly, the maximum deformation of the elastic deformation part 2133 is directly limited.
[0090] Furthermore, the deformable support 213 is an integral connection structure, that is, each part of the deformable support 213 (such as the fixed part 2132 and the elastic deformation part 2133) is made into an integral part that cannot be disassembled through a one-time molding process (such as injection molding, metal stamping and bending, precision casting, etc.). The connection between each part is reliable and has high stability, eliminating the assembly gap and connection loosening risk of the split design, and adapting to the long-term dynamic use requirements.
[0091] Furthermore, the main body 211 of the component and the deformable abutment 212 are integrally connected structures. That is, the main body 211 of the component and the deformable abutment 212 are made into an integral part that cannot be disassembled through a one-time molding process (such as injection molding, metal stamping and bending, precision casting, etc.). The connection between each part is reliable and has high stability, eliminating the assembly gap and connection loosening risk of the split design, and adapting to the needs of long-term use.
[0092] Furthermore, the main body 211 of the component has a support block 2112 and a sliding block 2113. The support block 2112 protrudes outward from the strip-shaped through hole 221. Two sliding blocks 2113 are arranged on one side of the support block 2112 parallel to the guide rail 220, and two sliding blocks 2113 are arranged on the other side parallel to the guide rail 220. The sliding blocks 2113 abut against the guide wall of the strip-shaped channel 222. The deformable abutment 212 is located between the two sliding blocks 2113. The support block 2112, as the main load-bearing structure, is used to support the flow-blocking component. The outward protrusion of the strip-shaped through hole 221 by the support block 2112 is to raise the connection position with the flow-blocking component and prevent the flow-blocking component from contacting the guide rail 220. The sliding blocks 2113 mainly undertake the guiding and sliding functions. The deformable abutment 212 is located between the two sliding blocks 2113, which can form a relatively symmetrical elastic abutment layout, ensuring that the moving component 210 is subjected to balanced force, avoiding unilateral force deviation, further enhancing the guiding and limiting effect, and effectively suppressing the vibration of the baffle under the impact of airflow.
[0093] Furthermore, the sliding block 2113 has a sliding portion 2114 protruding perpendicular to the length direction of the guide rail 220, and the sliding portion 2114 abuts against the guide wall of the strip channel 222. Compared to the entire side of the sliding block 2113 being in contact with the wall of the guide rail 220, the protruding sliding portion 2114 effectively reduces the actual contact area between the sliding block 2113 and the guide wall on the lateral side, thus helping to reduce sliding resistance.
[0094] In some embodiments, the movable component 210 and the flow deflector are engaged in a plug-in positioning fit. The plug-in positioning fit provides a clear assembly reference for the movable component 210 and the flow deflector. During assembly, positioning can be completed simply by aligning and inserting the corresponding plug-in structure, without the need for additional measurement and adjustment processes. This significantly shortens assembly time, reduces human error, and adapts to the needs of large-scale mass production.
[0095] For example, the movable component 210 has a protruding post on the side facing the flow deflector, and the flow deflector has a concave hole 319 that matches the protruding post, so that the movable component 210 and the flow deflector can be inserted and engaged to complete the positioning.
[0096] For example, the movable component 210 has a slot on the side facing the flow deflector, and the flow deflector has a hook that engages with the slot, so that the movable component 210 and the flow deflector can be inserted and engaged to complete the positioning.
[0097] Furthermore, the main body 211 of the component has a threaded hole 2115; the flow-blocking component has a through hole that mates with and is aligned with the threaded hole 2115; the lifting device for the flow-blocking component also includes a fastener, which passes through the through hole and is threadedly connected to the threaded hole 2115 to fix the flow-blocking component. The movable component 210 and the flow-blocking component are fixed by a threaded fastening connection. During assembly, a fastener (such as a screw or bolt) is passed through the through hole of the flow-blocking component, screwed into the threaded hole 2115 of the main body 211 of the component and tightened, thereby firmly connecting the main body 211 of the component and the flow-blocking component together.
[0098] Furthermore, the main body 211 is made of non-metallic material. In order to enhance the reliability of the threaded connection, the threaded hole 2115 in the main body 211 is not formed by tapping directly on its base material (such as plastic), but is achieved by embedding an independent metal nut. The nut is pre-embedded in the main body 211, and its internal thread constitutes the threaded hole 2115 for connection.
[0099] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
