Description

Technical Field

[0001] The invention relates to the technical field of motorcycle assembly, in particular to a laser scanning adjustment tool for the distance between a motorcycle fender and a wheel hub. Background Art

[0002] Motorcycle fenders are protective components installed above the wheels. Their main functions include: blocking mud and water splashes to improve riding comfort and safety; protecting mechanical components and reducing the impact and wear of foreign objects such as mud, sand, and gravel on key components such as the wheel hub, brake system, and chain; and optimizing aerodynamics to reduce wind resistance and improve high-speed driving stability.

[0003] The distance between the fender and the wheel hub (usually refers to the vertical distance between the inner edge of the fender and the outside of the tire) directly affects its protective effect and vehicle safety. During factory assembly, the main purpose of adjusting this distance is to be compatible with different tire sizes. For example, when replacing wide tires or high-tread off-road tires in the wheel hub, the distance needs to be readjusted.

[0004] Currently, the most common adjustment method is to manually loosen the bolts, visually observe that the fender moves to the appropriate distance relative to the wheel hub, and then re-tighten the bolts. Although the operation is simple, it cannot achieve millimeter-level fine-tuning, and has the disadvantages of insufficient accuracy and low standardization. Summary of the Invention

[0005] The purpose of the present invention is to provide a laser scanning and adjustment tool for the distance between a motorcycle fender and a wheel hub, which can form a quick-install connection with the front and rear brake discs of the motorcycle by utilizing a quick-clamping assembly, and cooperate with the insertion of the insert frame component into the insert cylinder through the insert column, and the paired side spring columns can form an interlocking effect for the quick-install connection between the quick-clamping assembly and the insert frame component; the setting of the synchronous rotating assembly can make the rotating inner rod slide relative to the rotating rod to adapt to the different clamping positions of the quick-clamping assembly, and utilize the transmission connection formed by the side scanning assembly and the synchronous rotating assembly to quickly and accurately scan and determine the distance between the end positions on both sides of the fender and the outside of the tire.

[0006] The objective of the present invention is achieved through such a technical solution: a laser scanning adjustment tool for the distance between a motorcycle fender and a wheel hub, comprising a quick-clamping assembly, a plug-in frame component, a synchronous rotating assembly, and a side scanning assembly, wherein the quick-clamping assembly comprises a plug-in cylinder, the plug-in frame component comprises a plug-in column, a rotating rod, and a rotating inner rod, the synchronous rotating assembly comprises a supporting rotating rod, and the side scanning assembly comprises a side swing rod;

[0007] The quick-clamp assemblies are arranged in pairs and are both quickly fixedly connected to the edge of the brake disc of the motorcycle. The plug-in cylinder is fixedly arranged in the quick-clamp assemblies. Both ends of each group of plug-in cylinders are slidably connected with paired side elastic columns that elastically press each other. One side of each group of quick-clamp assemblies is connected with a handle for controlling the clamping and loosening of the quick-clamp assemblies. The head end of the rotary rod is slidably connected to the head end of the rotary inner plug-in rod. The rotary inner plug-in rod and the main body of the rotary rod are both screwed with synchronous rotating shafts. The plug-in columns are arranged in pairs. The ends of the rotary rod and the rotary inner plug-in rod are respectively screwed with the ends of different plug-in columns, and the head end of the plug-in column is plugged into the plug-in cylinder;

[0008] One end of each set of synchronous rotating shafts is inserted with a synchronous toothed pulley. One end of the paired supporting rotating rods is screwed to the synchronous rotating shaft, and the other ends are screwed to each other. A follower toothed pulley is also screwed to the place where the supporting rotating rods are screwed to each other. A toothed belt is installed between the synchronous toothed pulley and the follower toothed pulley.

[0009] The other end of each set of synchronous rotating shafts is inserted with a swinging gear. One end of the side swing rod is screwed to the end of the plug-in column, and the other end is slidably connected to the eccentric end of the swinging gear.

[0010] The use process of the technical solution of the present invention is as follows:

[0011] The quick-clamp assembly forms a quick-release and quick-install connection with the edges of the front and rear brake discs of the motorcycle. The connection position of the quick-clamp assembly and the brake disc is determined according to the two ends of the fender. Visually install the two sets of quick-clamp assemblies on one side of the end position of the fender;

[0012] When the quick-clamp assembly is installed in the brake disc, the insert member is in a state of being separated from the quick-clamp assembly, which facilitates adjustment of the installation position of the quick-clamp assembly, and when the handle is not buckled into place, the quick-clamp assembly forms a preliminary clamping action with the edge of the brake disc;

[0013] After the quick-clamp assembly and the brake disc are installed, the sliding connection position of the rotary inner plug rod and the rotary rod is adjusted according to the distance between the two sets of plug-in cylinders, so that the head ends of the two sets of plug-in columns at different positions can be inserted into different plug-in cylinders respectively;

[0014] When the internal rod of the rotary joint is adjusted and moved relative to the rotary joint rod, the toothed belt installed between the synchronous toothed belt wheel and the follower toothed belt wheel will be in a tensioned state at all times, so that the two sets of synchronous toothed belt wheels can always maintain an effective transmission connection;

[0015] And when the handle is not buckled into place, the handle itself will not interfere with the insertion of the plug post into the plug barrel;

[0016] When the operating handle is buckled into place, the quick clamping assembly can clamp the brake disc into place. After the handle and the quick clamping assembly are buckled into place and the head end of the plug-in column is inserted into the plug-in tube and into place, the outer side elastic columns of the paired sliding side elastic columns just form an elastic snap connection with the main body of the handle, and the inner side elastic columns form an elastic snap connection with the head end of the plug-in column. The handle and the plug-in column will form a two-way squeezing on the paired side elastic columns, thereby forming an interlocking effect.

[0017] A laser scanning device for measuring the distance between the fender and the wheel hub (outside the tire) is connected to one end of the side sway bar. After the quick-clamp assembly and the insert frame are in place, rotating either set of swing gears, the transmission connection formed by the synchronous toothed pulley, the follower toothed pulley and the toothed belt, and the sliding connection formed by the eccentric end of the swing gear and the side sway bar, can drive the two sets of side sway bars to swing back and forth within a certain range.

[0018] While the two sets of side sway arms swing back and forth, the distance between the two ends of the fender and the wheel hub can be scanned and measured in real time with high precision, making it easy to accurately adjust the fender to different distances from the wheel hub.

[0019] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0020] (1) The present invention is based on the quick-install structure formed by the quick-clamp assembly itself. By rotating the handle, the quick-clamp assembly can realize the action of clamping and loosening the front and rear brake discs of the motorcycle; and in the process of rotating the handle to engage the quick-clamp assembly, the handle itself can be elastically engaged with the outer side spring column. After the head end of the plug-in column and the plug-in tube are plugged into place, the elastic engagement formed by the plug-in column on the inner side spring column can form an extrusion on both sides of the paired slidingly distributed side spring columns; that is, the elastic engagement formed by the handle and the outer side spring columns can not only improve the safety of the handle engagement and the locking of the quick-clamp assembly and the brake disc, but also improve the safety of the elastic engagement with the plug-in column by squeezing the side spring columns; at the same time, the squeezing formed by the plug-in column on the inner side spring column can also improve the safety effect of the elastic engagement between the side spring column and the handle that is engaged in place, thereby achieving the effect of safety interlocking;

[0021] (2) In order to adapt to the different quick-clamping assemblies being clamped to different positions of the brake disc, the present invention sets the rotating inner rod and the rotating rod to a sliding connection state, and a transmission mechanism consisting of a synchronous toothed pulley, a follower toothed pulley and a toothed belt, and a rotating structure consisting of a supporting rotating rod are set between the synchronous rotating shafts that are rotated in the rotating inner rod and the rotating rod. When the rotating inner rod is adjusted to a sliding position relative to the rotating rod, the rotating structure consisting of the supporting rotating rod can keep the toothed belt in a state of being tensioned at all times, thereby forming an installation position in which the quick-clamping assembly matches the insert frame component. When the rotating inner rod is sliding relative to the rotating rod, the two sets of swinging large gears can form an effective transmission connection at all times. Rotating one set of the swinging large gears can drive the two sets of side swing arms to swing back and forth within a certain range, which can not only improve the convenience and safety of the tool installation, but also improve the position accuracy of the fender relative to the wheel hub in combination with the use of a laser scanning device.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] like Figures 1-15 As shown, a laser scanning adjustment tool for the distance between a motorcycle fender and a wheel hub is provided. The quick-clamping components 1 are arranged in pairs and are both quickly fixed to the edge of the motorcycle's brake disc. The plug-in cylinder 109 is fixed in the quick-clamping component 1. Both ends of each group of plug-in cylinders 109 are slidably connected with paired side elastic columns 112 that elastically press each other. One side of each group of quick-clamping components 1 is connected to a handle 108 for controlling the clamping and loosening of the quick-clamping component 1. The head end of the rotary rod 204 is slidably connected to the head end of the rotary inner plug rod 205. The rotary inner plug rod 205 and the main body of the rotary rod 204 are both rotary A synchronous rotating shaft 207 is connected, and the plug-in columns 201 are arranged in pairs. The ends of the rotating rod 204 and the rotating inner plug rod 205 are respectively screwed to the ends of different plug-in columns 201. The head end of the plug-in column 201 is plugged into the plug-in tube 109. After the head end of the plug-in column 201 is inserted into the plug-in tube 109, the plug-in column 201 plugged in and the handle 108 snapped into place can be elastically engaged with the paired sliding side spring columns 112. The elastic engagement of the side spring columns 112 with the handle 108 and the elastic engagement with the plug-in column 201 can form an interlocking effect.

[0043] One end of each set of synchronous rotating shafts 207 is inserted with a synchronous toothed pulley 401, one end of the paired supporting rotating rods 402 is screwed to the synchronous rotating shaft 207, and the other ends are screwed to each other. A follower toothed pulley 404 is also screwed to the mutually screwed connection of the supporting rotating rods 402. A toothed belt 405 is sleeved and installed between the synchronous toothed pulley 401 and the follower toothed pulley 404, so that when the inserted rod 205 slides within a certain range relative to the screwed rod 204 in the screw connection, as the two sets of synchronous toothed pulleys 401 are displaced, the two sets of synchronous toothed pulleys 401 can still form an effective transmission connection through the follower toothed pulley 404;

[0044] The other end of each set of synchronous rotating shafts 207 is inserted with a swing gear 502. One end of the side swing rod 501 is screwed to the end of the plug-in column 201, and the other end is slidably connected to the eccentric end of the swing gear 502.

[0045] Here's how it works:

[0046] A brake disc is provided on one side of the front and rear wheels of the motorcycle. Since the brake disc is a standard-sized cylindrical structure, the tool can form a quick-release and quick-install connection with the edge of the brake disc through the quick-clamp assembly 1;

[0047] The connection position of the quick clamp assembly 1 and the brake disc is determined according to the two ends of the fender. Visually install the two sets of quick clamp assemblies 1 on one side of the end position of the fender;

[0048] When the quick-clip assembly 1 is installed in the brake disc, the insert member 2 is in a state of being separated from the quick-clip assembly 1, so that the installation position of the quick-clip assembly 1 can be adjusted conveniently. When the handle 108 is not locked in place, the quick-clip assembly 1 forms a preliminary clamping action with the edge of the brake disc.

[0049] After the quick-clamp assembly 1 and the brake disc are installed, the sliding position of the inner screw rod 205 and the screw rod 204 is adjusted according to the distance between the two sets of plug-in tubes 109, so that the head ends of the two sets of plug-in columns 201 at different positions can be inserted into different plug-in tubes 109 respectively;

[0050] Furthermore, since the support rotary rod 402 is screwed between the two sets of synchronous rotary shafts 207 and the support rotary rods 402 are screwed to each other, when the screw-in rod 205 is adjusted and moved relative to the screw-in rod 204, the toothed belt 405 sleeved between the synchronous toothed belt pulley 401 and the follower toothed belt pulley 404 is always in a tensioned state, so that the two sets of synchronous toothed belt pulleys 401 can always maintain an effective transmission connection;

[0051] Furthermore, when the handle 108 is not locked in place, the handle 108 itself will not interfere with the insertion of the plug-in column 201 into the plug-in cylinder 109;

[0052] The operating handle 108 is buckled into place, which can form the quick clamping assembly 1 to clamp the brake disc into place. After the handle 108 and the quick clamping assembly 1 are buckled into place and the head end of the plug-in column 201 is inserted into the plug-in tube 109 and into place, the outer side elastic columns 112 are elastically connected with the main body of the handle 108, and the inner side elastic columns 112 are elastically connected with the head end of the plug-in column 201. The handle 108 and the plug-in column 201 will form a two-way squeezing on the paired side elastic columns 112, thereby forming an interlocking effect.

[0053] A laser scanning device for measuring the distance between the fender and the wheel hub (outside the tire) is connected to one end of the side swing link 501. After the quick-clamp assembly 1 and the insert frame component 2 are installed in place, any one of the swing gears 502 is rotated. The transmission connection formed by the synchronous toothed pulley 401, the follower toothed pulley 404 and the toothed belt 405, and the sliding connection formed by the eccentric end of the swing gear 502 and the side swing link 501 can drive the two sets of side swing links 501 to swing back and forth within a certain range.

[0054] Since a laser scanning device is installed at one end of each set of side sway bars 501, and the laser scanning devices are respectively aligned with the ends of the fenders, the distances between the ends of the fenders and the wheel hubs can be scanned and measured in real time with high precision while the two sets of side sway bars 501 are swinging back and forth, making it easy to precisely adjust the fenders to different distances from the wheel hubs and then lock the fenders.

[0055] After the fender position is adjusted, the handle 108 is rotated to initially loosen the quick clamp assembly 1 from the brake disc, and the handle 108 is separated from the side spring column 112. The side spring column 112 on the outside pops out, and the extrusion force received by the side spring column 112 on the inside is reduced, making it convenient to pull the plug-in column 201 out of the plug-in tube 109. Then, the handle 108 is continued to be rotated to completely loosen the quick clamp assembly 1 from the brake disc, and the quick clamp assembly 1 is removed to complete the adjustment of the fender position.

[0056] The specific structure of the quick clamp assembly 1 is as follows Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, one end of the pressing sleeve 102 is screwed to one end of the fixed sleeve 101, and a clamping block 103 is fixed at the opposite position of the other end of the fixed sleeve 101 and the pressing sleeve 102. The clamping block 103 is made of nylon and can clamp the edge of the brake disc without damage.

[0057] The other end of the fixed sleeve 101 is screwed with a connecting rod 104, and the other end of the connecting rod 104 passes through the main body of the pressing sleeve 102 and is screwed to one end of the handle 108; the lower end of the main body of the connecting rod 104 is sleeved with a fixed sleeve 105, and the main body of the connecting rod 104 is also sleeved with a locking compression spring 106. One end of the locking compression spring 106 is clamped with the clamping sleeve 105, and the other end is clamped with the pressing sleeve 102, so that the pressing sleeve 102 can be elastically unscrewed relative to the fixed sleeve 101;

[0058] A pressing guide block 107 is also slidably connected to the main body of the locking compression spring 106, and the pressing guide block 107 is pressed against the outer side of the pressing sleeve 102 and slides tangentially with the eccentric structure at one end of the handle 108. By rotating the handle 108, the eccentric structure of the handle 108 and the pressing guide block 107 can be driven to form a sliding tangential action, so that the fixed sleeve 101 and the pressing sleeve 102 can be clamped and released through the clamping block 103.

[0059] The plug-in tube 109 is fixedly installed in the main body of the pressing sleeve 102, and a clearance hole facing the plug-in tube 109 is opened in the main body of the handle 108. Both sides of the clearance hole of the handle 108 are provided with spherical side slots 110;

[0060] Both ends of the plug-in cylinder 109 are fixedly connected to the elastic column slide 111, and the paired side elastic columns 112 are respectively slidably connected in different elastic column slides 111. The connecting compression spring 113 is connected between the paired side elastic columns 112, and the side elastic columns 112 can slide in the elastic column slide 111 without being separated from the elastic column slide 111.

[0061] The specific structure of the plug-in component 2 and the synchronous rotating component 4 is as follows Figure 7 、 Figure 8 and Figure 11 As shown, the rotary sleeve 202 is fixedly connected to the end of the plug-in column 201, and the ends of the rotary rod 204 and the rotary inner plug rod 205 are respectively screwed to different rotary sleeves 202;

[0062] An inner rotating seat 203 is fixed to the inner end of each set of plug-in columns 201, and one end of the side swing rod 501 is screwed to the inner rotating seat 203;

[0063] A synchronous rotary seat 206 is fixedly installed in the main body of the rotary rod 204 and the rotary inner insert rod 205. The synchronous rotary shaft 207 is screwed to the synchronous rotary seat 206. Side grooves 208 are opened on both sides of the head end of the rotary rod 204.

[0064] The follower shaft 403 is fixedly connected to the other end of one set of support rotating rods 402, the other set of support rotating rods 402 is screwed to the follower shaft 403, and the follower gear pulley 404 is also screwed to the follower shaft 403;

[0065] The plug-in positioning hole 209 and the plug-in slot 210 are correspondingly opened on both sides of the head end of the plug-in column 201. The outer end of the side elastic column 112 is a ball head structure. The plug-in positioning hole 209 and the spherical side card slot 110 are matched with the ball head structure size of the outer end of the side elastic column 112, so that the side elastic column 112 can easily form an elastic connection with the plug-in positioning hole 209 and the spherical side card slot 110 and disengage after a certain force is applied. The purpose of opening the plug-in slot 210 is to improve the smoothness of the disengagement of the side elastic column 112 from the plug-in positioning hole 209.

[0066] The specific structure of the lateral scanning component 5 is as follows Figure 12 、 Figure 13 and Figure 15 As shown, the eccentric column 503 is fixed to one side of the swing gear 502, and the swing gear 502 is slidably connected to the other end of the side swing link 501 through the eccentric column 503;

[0067] The outer side surfaces of each set of side swing arms 501 are fixedly connected to a pair of frame connection columns 504. One end of the scanning connection frame 505 is provided with a pair of sockets 506, and the other end is equipped with a laser scanning probe 509. The position of the laser scanning probe 509 at the other end of the scanning connection frame 505 can be adjusted both laterally and rotationally. After adjustment, the position of the laser scanning probe 509 is locked with the scanning connection frame 505, which is convenient for adapting to different on-site operating environments.

[0068] A fixing bolt seat 507 is fixedly mounted in the main body of one end of the scanning connection frame 505 opposite to the insertion hole 506, and each set of fixing bolt seats 507 is threadedly connected with a fixing bolt 508;

[0069] After the quick-clamp assembly 1 and the insert frame member 2 are installed, the scanning connection frame 505 can be inserted into the frame connection column 504 through the socket 506 at one end with the tightening bolt 508 loosened. The scanning connection frame 505 is then firmly connected to the frame connection column 504 by tightening the tightening bolt 508.

[0070] The two sets of laser scanning probes 509 are both connected to an external handheld detection device, and can feed back the scanned data information to the handheld detection device in real time.

[0071] Preferably, the eccentric locking assembly 3 can improve the safety and stability of the sliding adjustment of the rotating rod 204 and the rotating inner rod 205 to any position. Figure 9 and Figure 10As shown, both outer sides of the head end of the screw rod 204 are fixedly connected with fixed racks 301, one end of the L-shaped connecting block 302 is fixedly connected to the outer side of the head end of the screw inner plug rod 205, and the side groove 208 can eliminate the interference with the L-shaped connecting block 302 and the interference with the synchronous rotating shaft 207 screwed into the main body of the screw inner plug rod 205; the locking tooth body 303 and the elastic sliding block 304 are both slidably connected to the groove body opened in the L-shaped connecting block 302, and the top spring 308 is fixedly connected to the head end of the L-shaped connecting block 302. 05 is fixedly connected between the locking tooth body 303 and the elastic sliding block 304; a fixed nut 308 is fixedly installed in the outer end body of the L-shaped connecting block 302, and the head end of the adjusting bolt 306 passes through the body of the L-shaped connecting block 302 and is threadedly connected to the fixed nut 308; a hexagonal sliding column 309 is fixedly connected to the body of the adjusting bolt 306, and an eccentric wheel 307 is slidably connected to the hexagonal sliding column 309, and the eccentric wheel 307 is slidably connected to the groove opened in the L-shaped connecting block 302 The outer surface of the eccentric wheel 307 slides tangentially with the side surface of the elastic sliding block 304 by screwing the adjusting bolt 306, driving the sliding tangential cooperation formed by the eccentric wheel 307 at different positions and the side surface of the elastic sliding block 304, and adjusting the tightness of the locking tooth body 303 connected between the elastic sliding block 304 and the locking tooth body 303, so that when the inner rod 205 is adjusted relative to the screw rod 204, the eccentric wheel 307 is rotated to the top spring 305 In the released position, the locking tooth body 303 can form an elastic locking operation with the fixed rack 301 without affecting the adjustment of the rotating inner rod 205 relative to the rotating rod 204. After the adjustment operation of the rotating inner rod 205 relative to the rotating rod 204 is completed, the eccentric wheel 307 is rotated to the position where the top spring 305 is pressed, and the locking tooth body 303 is clamped with the fixed rack 301, which can ensure the safety and reliability of the rotating inner rod 205 after the sliding position adjustment relative to the rotating rod 204 is completed.

[0072] Preferably, a safety rotating member 6 is installed between the adjusting bolt 306 and the L-shaped connecting block 302, which can improve the convenience and safety of rotating the swinging gear 502. Figure 12 and Figure 14306 , and the eccentric wheel 307 is rotated to the limit position of the top spring 305. The rotation of the bolt 306 can just drive the side connecting seat 601 to move to the manual gear 602 and engage with the swinging gear 502 rotated in the rotating inner rod 205. By utilizing the different transmission ratios formed by the manual gear 602 and the swinging gear 502, the swinging gear 502 can be operated with less force and save effort, thereby forming a stable and slow reciprocating swinging movement of the side swing arm 501 and the laser scanning probe 509 fixed to the side swing arm 501 through the scanning connecting frame 505. The scanning action of the laser scanning probe 509 at the gap position between the end position of the fender and the outside of the tire is utilized to realize high-precision real-time measurement and scanning of the distance between the fender and the outside of the tire during the position adjustment of the fender and the outside of the tire.
