Description

Technical Field

[0001] This invention relates to the field of inverted tricycle technology, and more specifically to inverted tricycles. Background Technology

[0002] An inverted tricycle is a unique vehicle design. It typically has two front wheels and one rear wheel; the two front wheels provide steering, while the rear wheel provides drive. In complex terrain, inverted tricycles offer better stability than two-wheeled vehicles, especially when turning, as their tire grip is stronger, allowing the driver to maintain balance more easily. The inverted tricycle utilizes a front suspension to connect the front wheels to the frame, transmitting forces and torques between the front wheels and the frame, and cushioning impacts from uneven road surfaces.

[0003] The current inverted tricycles have a front suspension that provides independent cushioning for the two front wheels, which allows the front wheels to have better yaw and shock absorption. However, it also gives the front wheels a lot of yaw freedom, making the vehicle prone to swaying when braking. If the ground is uneven or you are turning and braking in a curve, there is a risk of tipping over.

[0004] Meanwhile, the connecting brackets often use a Chinese patent (publication number CN205971626U) that discloses an inverted tricycle headlight bracket device, which has the defect that the cantilever end of the connecting bracket is prone to shaking, which can easily cause damage to the connection between the connecting bracket and the vehicle frame.

[0005] Furthermore, since the front wheel of a three-wheeled motorcycle needs to handle steering, the front fender also needs to steer accordingly. Therefore, the front fender is typically fixed to the steering knuckle, which steers synchronously with the front wheel, via a fender bracket. This allows the front fender to move in sync with the front wheel's steering motion. However, existing front fender brackets are usually linear, extending straight from the steering knuckle to the fender and fixedly connected to it. While the fender bracket can be tilted to avoid the front wheel and meet its support requirements, it encroaches on the installation space between the two front wheels of the three-wheeled motorcycle for components such as the steering mechanism and yaw mechanism. Summary of the Invention

[0006] The purpose of this invention is to provide an inverted tricycle that solves the defects of existing inverted tricycles, such as the vehicle swaying and overturning easily when the front suspension is braked, the cantilever end of the connecting bracket easily shaking and causing damage to the connection between the connecting bracket and the frame, and the defect of the front fender bracket occupying the installation space of the steering mechanism and the yaw mechanism.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an inverted tricycle, comprising: a headlight, a front mudguard, a mounting bracket, a sway mechanism, a locking mechanism, and a steering mechanism;

[0008] The headlight is mounted on a headlight mounting bracket. The headlight mounting bracket includes a bracket body and a mounting ear. One end of the bracket body is located on the front side of the inverted tricycle frame, and the other end extends from the top of the inverted tricycle frame to the rear side of the inverted tricycle frame. The bracket body at the front side of the inverted tricycle frame has a first connecting part for connecting to the front side of the inverted tricycle frame, and the bracket body at the rear side of the inverted tricycle frame has a second connecting part for connecting to the rear side of the inverted tricycle frame. The mounting ear is fixedly connected to the bracket body and is located on the front side of the inverted tricycle frame. The mounting ear has a first mounting hole for connecting the inverted tricycle headlight.

[0009] The front fender is fixed by a front fender bracket; the front fender bracket includes a bracket body, the bracket body having a first connector, a first bent section, a second bent section, a third bent section, a fourth bent section, and a second connector arranged sequentially; the first connector is used to connect with the steering knuckle of the front wheel of the tricycle; the first bent section extends from the end of the first connector near the spoke of the front wheel toward the rim of the front wheel, and the first bent section is clearance-fitted with the spoke of the front wheel; the second bent section extends laterally to the outside of the rim of the front wheel, and the second bent section is clearance-fitted with the rim of the front wheel; the third bent section extends along a plane perpendicular to the axial direction of the front wheel in a direction away from the first connector; the fourth bent section extends along the axial direction of the front wheel toward the outside of the front wheel; the second connector is used to connect with the fender of the front wheel.

The caliper body is fixedly mounted on the mounting bracket by the fixing assembly. The caliper body is an inverted U-shape. The locking baffle is fixedly connected to the inside of the caliper body. The locking pump is fixedly mounted on the caliper body. The locking pump has an output end that can extend toward the locking baffle. Friction plates are fixedly connected to both the locking baffle and the output end of the locking pump. The output end of the locking pump drives the corresponding friction plate to move closer to the other friction plate to clamp the brake pad together.

[0013] The steering mechanism drives the two steering knuckles to deflect synchronously. Further defined, the bracket body includes a first support rod and a second support rod connected at one end. The first and second support rods are formed by bending a single support rod, both bent into an arch shape with an opening facing downwards. One end of each support rod is located at the front of the inverted tricycle frame, and the other end is located at the rear of the inverted tricycle frame. Mounting ears are fixedly connected to the inner sides of the arches of both the first and second support rods. The mounting ears corresponding to the first support rod form reinforcing ribs for strengthening the first support rod; the mounting ears corresponding to the second support rod form reinforcing ribs for strengthening the second support rod. The portions of the first and second support rods located at the rear of the inverted tricycle frame are connected together by a reinforcing rod. A second mounting hole for mounting a turn signal is provided on each mounting ear.

[0014] Further defined, the first cantilever has a positioning protrusion and a first mounting hole, the positioning protrusion being a strip-shaped protrusion; the connecting piece has a second mounting hole and a positioning hole, the positioning protrusion being engaged in the positioning hole; the connecting piece is connected to the first cantilever by a first mounting bolt, the threaded section of the first mounting bolt passing through the second mounting hole and then threadedly connected to the first mounting hole.

[0015] Further defining the steering mechanism, it includes: a steering column, a rocker arm, a connecting assembly, a connecting joint, a first connecting arm, and a second connecting arm; one end of the rocker arm is rotatably connected to the mounting bracket, and the steering column drives the rocker arm to swing about a rotation point centered on a rotation point via the connecting assembly, the rotation point being the rotational connection point between the rocker arm and the mounting bracket; two connecting joints are symmetrically arranged about the rocker arm, and each end of the connecting joint has a first rotating part and a second rotating part, the first rotating part being rotatably connected to the end of the rocker arm away from the mounting bracket, the connecting joint forming a first rotation plane with the rocker arm, and the second rotating part being rotatably connected to a first connecting arm. A connecting arm, wherein the first connecting arm and the corresponding connecting joint form a second rotation plane, the second rotation plane being perpendicular to the first rotation plane, and the end of the first connecting arm away from the connecting joint being connected to a second connecting arm; a steering knuckle is rotatably connected to a steering shaft, the end of the steering shaft being fixedly connected to a steering head, the steering head being rotatably connected to the end of the second connecting arm away from the first connecting arm; the steering head and the second connecting arm form a third rotation plane, the third rotation plane being parallel to the second rotation plane; the rotation plane of the steering shaft is a fourth rotation plane, the fourth rotation plane being parallel to the first rotation plane.

[0016] Further specifying, the connecting assembly includes a steering rocker arm and a steering joint. One end of the steering rocker arm is fixedly connected to the steering column, and the other end of the steering rocker arm is connected to the first end of the steering joint via a first hinge. The second end of the steering joint is connected to the end of the rocker arm away from the mounting bracket via a second hinge. The rocker arm includes an integrally formed first connecting rod, a second connecting rod, a first rotating sleeve, a second rotating sleeve, and a fixed fork. The first rotating sleeve is rotatably connected to the mounting bracket via a connecting shaft. The second rotating sleeve is connected to the outside of the fixed fork and is connected to the steering joint via a second hinge. A first rotating shaft is connected to the inside of the fixed fork, and is rotatably connected to the first rotating part via the first rotating shaft. The two ends of the first connecting rod are respectively connected to the first rotating sleeve and the second rotating sleeve, and the two ends of the second connecting rod are respectively connected to the fixed fork and the second rotating sleeve.

[0017] The first hinge and the second hinge are further defined as ball joint assemblies; the first connecting arm includes a crank arm, the two ends of which have a first connecting fork and a first connecting sleeve respectively, the first connecting fork is rotatably connected to the second rotating part through the second rotating shaft, one end of the second connecting arm passes through the first connecting sleeve, and the second connecting arm is rotatably connected to the first connecting sleeve.

[0018] The present invention is further configured such that the second connecting arm includes an adjusting shaft and a second connecting sleeve; one end of the adjusting shaft passes through the first connecting sleeve and is rotatably connected to the first connecting sleeve; the other end of the adjusting shaft passes through the second connecting sleeve and is threadedly connected to the second connecting sleeve; a second connecting fork is fixedly connected to the end of the second connecting sleeve away from the adjusting shaft, and a third rotating shaft is installed on the inner side of the second connecting fork and is rotatably connected to the steering head.

[0019] The present invention is further configured such that a locking nut is threaded onto the adjusting shaft, and the locking nut abuts against the second connecting sleeve.

[0020] The present invention is further configured such that a hexagonal head is fixedly connected to the adjusting shaft, and the hexagonal head is located between the anti-reverse nut and the first connecting sleeve.

[0021] In summary, this solution offers at least the following benefits: When braking, steering, or experiencing road bumps, the locking mechanism limits the swing speed of the first cantilever, thereby limiting the sway of the yaw mechanism, stabilizing the vehicle body, and preventing the inverted tricycle from tipping over. Furthermore, when the inverted tricycle is parked, the locking mechanism limits the swing of the first cantilever, thus limiting the sway of the yaw mechanism and preventing the inverted tricycle from tipping over to the side. Because the locking mechanism controls the swing of the first cantilever by having a locking pump move one friction pad close to another to clamp the brake pad, the brake pad receives continuous and stable resistance. This allows the locking mechanism to stably limit the swing of the first cantilever, ensuring the stability of the inverted tricycle during riding and preventing tipping. Simultaneously, the headlight bracket device using this solution is securely connected, avoiding the defect of the cantilever end of the connecting bracket being prone to wobbling. It also solves the problem of the front fender bracket encroaching on the installation space of the steering mechanism, yaw mechanism, and other components between the two front wheels of the inverted tricycle.

[0040] like Figure 1-18 As shown, the inverted tricycle includes: a headlight, a front fender, a mounting bracket, and a yaw locking mechanism, wherein the yaw locking mechanism includes a yaw mechanism, a locking mechanism, and a steering mechanism;

[0041] Among them, such as Figures 1-3As shown, the headlight is mounted on a headlight mounting bracket; the headlight mounting bracket includes a bracket body A1 and mounting ears A4. The left end of the bracket body A1 is located on the front side of the inverted tricycle frame. The right end of the bracket body A1 crosses over the top of the inverted tricycle frame and extends to the rear side of the inverted tricycle frame. Specifically, the top of the inverted tricycle frame refers to the portion of the top of the inverted tricycle frame covered by the front panel A8 below the handlebars. The bracket body A1 is an arched shape with its opening facing downwards. The shape of this arch conforms to the shape of the inverted tricycle body shell to reduce the space occupied by the mounting bracket body A1. The end of the bracket body A1 located on the front side of the inverted tricycle frame has a first connecting part A2 for connecting to the front side of the inverted tricycle frame, and the end of the bracket body A1 located on the rear side of the inverted tricycle frame has a second connecting part A3 for connecting to the rear side of the inverted tricycle frame. Because the middle part of the bracket body A1 spans the top of the inverted tricycle frame, and the first connecting part A2 and the second connecting part A3 are respectively connected to the front and rear sides of the inverted tricycle frame, the first connecting part A2 and the second connecting part A3 can share the impact force generated by the back-and-forth swaying of the bracket body A1 during the deceleration or acceleration of the inverted tricycle, and can work together to prevent the bracket body A1 from swaying back and forth, thereby enhancing the stability of the bracket body A1. The mounting ear A4 is fixedly connected to the bracket body A1. The mounting ear A4 is located on the front side of the inverted tricycle frame, and the mounting ear A4 has a first mounting hole A5 for connecting the inverted tricycle headlight A9. The headlight is connected to the mounting ear A4 through the first mounting hole A5, facilitating the illumination of the front by the inverted tricycle headlight A9 at night. The bracket body A1 includes a first support rod A101 and a second support rod A102 connected at the left end. The first support rod A101 and the second support rod A102... Made from a single bent support rod, the projections of the first support rod A101 and the second support rod A102 on the horizontal plane are U-shaped. Both the first support rod A101 and the second support rod A102 are bent into downward-opening arches, and their shapes fit snugly against the outer shell of the inverted tricycle. The left ends of both the first support rod A101 and the second support rod A102 are located on the front side of the inverted tricycle frame, and the right ends are located on the rear side of the inverted tricycle frame. The first support rod A101 and the second support rod A102 are spaced apart, with the distance between them sufficient to accommodate the inverted tricycle's headlight A9. Because the first support rod A101 and the second support rod A102 are made from a single bent support rod, the number of welding points is reduced, resulting in good overall integrity of the bracket body A1 and reducing the difficulty of processing.The first connecting part A2 is located on the part where the first support rod A101 and the second support rod A102 connect. The second connecting part A3 is located on the rear side of the inverted tricycle frame where the first support rod A101 and the second support rod A102 are located. The first connecting part A2 is a connecting hole, which facilitates bolt connection with the frame of the inverted tricycle. The inner sides of the first support rod A101 and the second support rod A102 are both fixedly connected to mounting ears A4. Both ends of the first mounting ear A4 are fixedly connected to the inner side of the first support rod A101. The area enclosed between the first mounting ear A4 and the first support rod A101 is triangular, thus forming a... The first support rod A101 has reinforcing ribs; both ends of the second mounting ear A4 are fixedly connected to the inner side of the second support rod A102. The area enclosed between the second mounting ear A4 and the second support rod A102 is triangular, thus forming reinforcing ribs for the second support rod A102, thereby enhancing the stability of the first and second support rods A101 and A102. The portions of the first and second support rods A101 and A102 located at the rear of the inverted tricycle frame are connected by a reinforcing rod A7. One end of the reinforcing rod A7 is fixedly connected to the first support rod A101, and the other end is fixedly connected to the second support rod A102. This makes the fixation between the first and second support rods A101 and A102 more stable, enhancing the stability of the bracket body A1. The mounting ear A4 has a second mounting hole A6 for mounting the turn signal, located above the first mounting hole A5. The second mounting hole A6 facilitates the installation of the turn signal and makes the structure between the headlight and the turn signal compact.

[0042] like Figures 4-6As shown, the front fender is fixed by a front fender bracket; the front fender bracket includes a bracket body, which has a first connector B1, a first bent section B2, a second bent section B3, a third bent section B4, a fourth bent section B5, and a second connector B6 arranged sequentially from bottom to top. The first connector B1 is used to connect with the steering knuckle B7 of the front wheel of the tricycle; the first bent section B2 extends from the end of the first connector B1 near the spoke of the front wheel toward the rim of the front wheel, and the first bent section B2 is clearance-fitted with the spoke of the front wheel. The second bent section B3 extends laterally to the outside of the rim of the front wheel, and the second bent section B3 is clearance-fitted with the inside of the rim of the front wheel. The third bent section B4 extends along a plane perpendicular to the axial direction of the front wheel in a direction away from the first connector B1. The fourth bent section B5 extends along the axial direction of the front wheel toward the outside of the front wheel, and the second connector B6 is used to connect with the front wheel fender B14. The fourth bending section B5 is located inside the mudguard B14. The fourth bending section B5 is arched to facilitate a fit with the wheel surface of the front wheel and the shape of the mudguard B14. The bracket body includes a first support rod B8 and a second support rod B9. Both the first support rod B8 and the second support rod B9 have a first connector B1, a first bending section B2, a second bending section B3, a third bending section B4, a fourth bending section B5, and a second connector B6. The first support rod B8 and the second support rod B9 are both welded to their corresponding first connectors B1 and B6. The first support rod B8 and the second support rod B9 are connected by a reinforcing rod B10. Both ends of the reinforcing rod B10 are fixedly connected to the first support rod B8 and the second support rod B9, respectively, and the fixed connection between the reinforcing rod B10 and the first support rod B8 and the second support rod B9 is by welding. A first connecting piece B1, connected to a first support rod B8, is fixedly connected to a third support rod B11. The third support rod B11 has a first bent section B2, a second bent section B3, a third bent section B4, and a fourth bent section B5. The fourth bent section of the third support rod B11 is fixedly connected to a second connecting piece B6, which is connected to the first support rod B8. The fixed connection between the third support rod B11 and the second connecting piece B6 is by welding. The first connecting piece B1 is a connecting lug plate with a through hole B13. The through hole B13 allows the threaded section of the bolt connecting to the steering knuckle B7 of the front wheel to pass through. The connecting lug plate is fixed to the steering knuckle B7 by the bolt. Two first connectors B1 are provided at intervals corresponding to the first support rod B8. The two first connectors B1 sandwich the lower ends of the first support rod B8 and the third support rod B11 in the middle. The two first connectors B1 are welded to the lower ends of the first support rod B8 and the third support rod B11 respectively, so that the connection between the first support rod B8 and the third support rod B11 and the corresponding first connectors B1 is more stable.The second connector B6 is a connecting post, with a threaded hole B12 at the center of the connecting post. The mudguard B14 is connected to the connecting post by bolts. Two second connectors B6 are provided at intervals along the width direction of the mudguard B14 on the fourth bending section B5.

[0043] Working Principle: Because the bracket body has a first bent section B2, a second bent section B3, a third bent section B4, and a fourth bent section B5, the bracket body is partially housed inside the front wheel rim, thus reducing the installation space occupied by the bracket body and increasing the installation space for other components between the two front wheels. The mudguard B14 is supported by a first support rod B8 and a second support rod B9, making the connection between the mudguard B14 and the front wheel steering knuckle B7 more stable. The first support rod B8 and the second support rod B9 are connected by a reinforcing rod B10, further enhancing the stability between them. The stability between the first connecting piece B1 and the second connecting piece B6 corresponding to the first support rod B8 is further enhanced by the third support rod B11, strengthening the support capacity for the mudguard B14. Because the fourth bending section B5 is located inside the mudguard B14, it provides better support for the mudguard B14, preventing it from moving closer to the front wheel surface if the connection between the mudguard B14 and the second connecting member B6 becomes loose, thus reducing safety risks. Since the second connecting member B6 is a connecting post with a threaded hole B12, the mudguard B14 is connected to the connecting post via bolts, facilitating its installation.

[0044] like Figures 7-18 As shown, the inverted tricycle also includes a mounting frame 1, a swaying mechanism 2, a locking mechanism 3, and a steering mechanism 4. The mounting frame 1 is plate-shaped and has a first clearance hole 5, a second clearance hole 6, and a third clearance hole 7. The first clearance hole 5 is located near the upper end of the mounting frame 1, and the second clearance hole 6 is located near the lower end of the mounting frame 1. The mounting frame 1 is fixedly installed on the frame of the inverted tricycle.

[0045] The yaw mechanism 2 includes a shock absorber 201, two first cantilever arms 202, two second cantilever arms 204, and two steering knuckles 205. Steering connectors 206 are pivotally connected to both the top and bottom ends of each steering knuckle 205, which is used to connect the front wheels of the inverted tricycle. The two first cantilever arms 202 and two second cantilever arms 204 are symmetrically arranged on the left and right sides of the mounting frame 1. The first ends of the two first cantilever arms 202 are pivotally connected to the upper section of the mounting frame 1, and the second ends are pivotally connected to the two steering connectors 206 located at the top of the steering knuckles 205, respectively. The first ends of the two second cantilever arms 204 are pivotally connected to the lower section of the mounting frame 1, and the second ends are pivotally connected to the two steering connectors 206 located at the bottom of the steering knuckles 205, respectively. Specifically, a first fixed shaft 209 is fixedly installed in the first clearance hole 5 on the mounting frame 1, and a second fixed shaft 210 is fixedly installed in the second clearance hole 6. The first ends of both first cantilever arms 202 are rotatably connected to the first fixed shaft 209, and the first ends of both second cantilever arms 204 are rotatably connected to the second fixed shaft 210. Each of the two second cantilever arms 204 is fixedly mounted with a shock-absorbing connector 208. The two ends of a shock absorber 201 are respectively connected to the two shock-absorbing connectors 208, and the shock absorber 201 is located within the third clearance hole 7. The connection between the shock absorber 201 and the shock-absorbing connector 208 is a hinged connection, and the shock absorber 201 is existing technology. The locking mechanism 3 includes a swing plate 301, a locking clamp body 303, a locking stop plate 304, a locking pump 306, and a fixing assembly 305. The swing plate 301 includes an integrally formed brake plate 3011 and a connecting plate 3012, with the connection point between the brake plate 3011 and the connecting plate 3012 located in the middle of the connecting plate 3012. The connecting piece 3012 is fixedly mounted on the first cantilever 202 located on the left side. The brake pad 3011 is arc-shaped, with the center of the arc of the brake pad 3011 located at the center of the swing of the first cantilever 202 around the mounting bracket 1, so that the first cantilever 202 and the brake pad 3011 swing around the same center. The caliper body 303 is fixedly mounted on the mounting bracket 1 by the fixing assembly 305. The caliper body 303 is an inverted U-shape, and the locking stop 304 is fixedly connected to the inside of the caliper body 303. The locking pump 306 is fixedly mounted on the caliper body 303 and has an output end that can extend toward the locking stop 304. Friction pieces 307 are fixedly connected to both the locking stop 304 and the output end of the locking pump 306. The output end of the locking pump 306 drives the corresponding friction piece 307 to move closer to the other friction piece 307 to jointly clamp the brake pad 3011. The locking pump 306 employs an electric or hydraulic push rod, as is available in the prior art, to enable the two friction pads 307 to output a stable clamping force on the brake pad 3011, thereby facilitating the control of the swing pad 301's swing and consequently the swing of the first connecting arm 407. The steering mechanism 4 drives the two steering knuckles 205 to deflect synchronously.

[0046] By adopting the above technical solution, during use, the steering mechanism 4 drives the two steering knuckles 205 to deflect synchronously, thereby driving the two front wheels to deflect, facilitating turning. When braking, steering, or on bumpy roads, the locking mechanism 3 limits the swing speed of the first cantilever 202, thereby limiting the sway of the sway mechanism 2, thus stabilizing the vehicle and preventing the inverted tricycle from tipping over. Furthermore, when the inverted tricycle is parked, the locking mechanism 3 can limit the swing of the first cantilever 202, thereby limiting the sway of the sway mechanism 2, thus preventing the inverted tricycle from tipping over to the side when parked. Since the locking mechanism 3 controls the swing of the first cantilever 202 by the locking pump 306 driving one friction plate 307 to approach another friction plate 307 to clamp the brake pad 3011, the brake pad 3011 receives continuous and stable resistance. This allows the locking mechanism 3 to stably limit the swing of the first cantilever 202, thus ensuring the stability of the inverted tricycle during riding and preventing tipping over.

[0047] To facilitate the installation of the locking clamp body 303 onto the mounting bracket 1, based on the above technical solution, the fixing assembly 305 further includes a fixing connecting plate 3051, two fixing support plates 3052, two first fixing bolts 3054, two second fixing bolts 3055, and two third fixing bolts 3056. The fixing support plate 3052 has two first threaded holes and is integrally formed with a fixing ear plate 3053. The fixing ear plate 3053 has a first through hole for the first fixing bolts 3054 to pass through. The mounting bracket 1 has a second through hole for the first fixing bolts 3054 to pass through. Both fixing ear plates 3053 are fixed to the mounting bracket 1 by a first fixing bolt 3054. The threaded section of the first fixing bolt 3054 passes through the first through hole and the corresponding second through hole, and cooperates with a nut to fix the fixing ear plate 3053 to the mounting bracket 1. The fixed connecting plate 3051 has two second threaded holes and two third through holes. The threaded section of the second fixing bolt 3055 passes through the third through hole and is threadedly connected to the first threaded hole. The clamp body 303 has a fourth through hole for the third fixing bolt 3056 to pass through. The threaded section of the third fixing bolt 3056 passes through the fourth through hole and is threadedly connected to the corresponding second threaded hole, thereby fixing the clamp body 303 and the fixed connecting plate 3051 together.

[0048] To enhance the stability of the connection between the first cantilever 202 and the connecting piece 3012, based on the above technical solution, the first cantilever 202 further includes a positioning protrusion 203 and a first mounting hole, the positioning protrusion 203 being a strip-shaped protrusion; the connecting piece 3012 has a second mounting hole 3013 and a positioning hole 3014, the positioning protrusion 203 being engaged within the positioning hole 3014. Preferably, three second mounting holes 3013 are spaced apart, located sequentially at the left end, middle, and right end of the connecting piece 3012, and three first mounting holes are correspondingly provided for the second mounting holes 3013. The connecting piece 3012 is connected to the first cantilever 202 via a first mounting bolt 302, the threaded section of the first mounting bolt 302 passing through the second mounting hole 3013 and then threadedly connected to the first mounting hole. Since the connecting piece 3012 is connected to the first cantilever 202 by three first mounting bolts 302, and the positioning protrusion 203 cooperates with the positioning hole 3014, the connecting piece 3012's ability to resist deformation along the swing direction of the first cantilever 202 is enhanced, thereby enhancing the stability of the connection between the first cantilever 202 and the connecting piece 3012.

[0049] Based on the above technical solution, the steering mechanism 4 further includes: a steering column 401, a swing arm 402, a connecting assembly 403, a connecting joint 404, a first connecting arm 407, and a second connecting arm 408. The rear end of the swing arm 402 is rotatably connected to the mounting bracket 1. The steering column 401 drives the swing arm 402 to swing around a pivot point via the connecting assembly 403. The pivot point is the rotatable connection point between the swing arm 402 and the mounting bracket 1. Two connecting joints 404 are symmetrically arranged around the swing arm 402, and the two connecting joints 404 are arranged symmetrically to the left and right. The two ends of the connecting joint 404 are respectively provided with a first rotating part 405 and a second rotating part 406. The first rotating part 405 is rotatably connected to the front end of the swing arm 402. The connecting joint 404 and the swing arm 402 form a first rotating plane, which is a vertical plane. The second rotating part 406 is rotatably connected to the first connecting arm 407. The first connecting arm 407 and the corresponding connecting joint 404 form a second rotating plane, which is perpendicular to the first rotating plane. The first connecting arm 407 is connected to a second connecting arm 408 at the end furthest from the connecting joint 404. A steering knuckle 205 is rotatably connected to a steering shaft 207, and a steering head 409 is connected to the front end of the steering shaft 207. The steering head 409 is fixedly connected to the shaft of the steering knuckle 205. The steering head 409 is rotatably connected to the end of the second connecting arm 408 furthest from the first connecting arm 407. The steering head 409 and the second connecting arm 408 form a third rotation plane, which is parallel to the second rotation plane. The rotation plane of the steering shaft 207 is a fourth rotation plane, which is parallel to the first rotation plane.

[0050] By adopting the above technical solution, when adjusting the steering of the front wheel, the steering column 401 is rotated. The steering column 401 drives the swing arm 402 to swing around the rotation point through the connecting component 403. The end of the swing arm 402 away from the mounting bracket 1 drives the connecting joint 404 to swing. When the connecting joint 404 swings, it pulls the first connecting arm 407, the first connecting arm 407 pulls the second connecting arm 408, the second connecting arm 408 pulls the steering head 409, the steering head 409 pulls the steering shaft 207, and the steering shaft 207 pulls the connecting piece, causing the connecting piece to deflect, thereby driving the front wheel of the three-wheeled motorcycle to deflect. Since the connecting joint 404, the first connecting arm 407, the second connecting arm 408, and the steering knuckle 205 are all symmetrically provided in two sets, the two front wheels of the three-wheeled motorcycle can deflect synchronously.

[0051] Based on the above technical solution, the connecting component 403 further includes a steering rocker arm 4031 and a steering joint 4032. One end of the steering rocker arm 4031 is fixedly connected to the steering column 401, and the other end of the steering rocker arm 4031 is connected to the first end of the steering joint 4032 through a first hinge 4033. The second end of the steering joint 4032 is connected to the end of the swing arm 402 away from the mounting bracket 1 through a second hinge 4034.

[0052] By adopting the above technical solution, since the steering rocker arm 4031 is connected to the steering joint 4032 via the first hinge 4033, and the steering joint 4032 is connected to the swing arm 402 via the second hinge 4034, when the steering column 401 is rotated, the steering rocker arm 4031 pulls the steering joint 4032, and the steering joint 4032 pulls the swing arm 402, thereby causing the swing arm 402 to swing. Because a steering joint 4032 is added between the steering rocker arm 4031 and the swing arm 402, the mounting position of the steering column on the frame can be appropriately adjusted, which is beneficial for the steering column 401 and the swing arm 402 to avoid the internal structure of the frame, making the frame structure more flexible. To allow for adjustments to the mounting position of the steering column 401 in more directions, preferably, both the first hinge 4033 and the second hinge 4034 adopt ball joint assemblies from the prior art.

[0053] Based on the above technical solution, the swing arm 402 further includes an integrally formed first connecting rod 4021, a second connecting rod 4022, a first rotating sleeve 4023, a second rotating sleeve 4024, and a fixed fork 4025. The first rotating sleeve 4023 is rotatably connected to the mounting frame 1 via a connecting shaft 4026, which is vertically oriented and connected to the mounting frame 1. To reduce wear between the connecting shaft 4026 and the first rotating sleeve 4023, preferably, a first bearing 4028 is installed inside the first rotating sleeve 4023, and the connecting shaft 4026 is installed inside the first bearing 4028. The second rotating sleeve 4024 is connected to the outside of the fixed fork 4025 and is located in the upper middle part of the fixed fork 4025. The second rotating sleeve 4024 is connected to the steering joint 4032 via the second hinge 4034; the inner side of the fixed fork 4025 is connected to the first rotating shaft 4027, which is rotatably connected to the first rotating part 405; the two ends of the first connecting rod 4021 are respectively connected to the first rotating sleeve 4023 and the second rotating sleeve 4024, and the two ends of the second connecting rod 4022 are respectively connected to the fixed fork 4025 and the second rotating sleeve 4024; the front ends of the first connecting rod 4021 and the second connecting rod 4022 are close to each other, and the rear ends of the first connecting rod 4021 and the second connecting rod 4022 are far apart, thereby providing support for the second rotating sleeve 4024 and the fixed fork 4025. By adopting the above technical solution, the swing arm 402 is integrally formed from the first connecting rod 4021, the second connecting rod 4022, the first rotating sleeve 4023, the second rotating sleeve 4024 and the fixed fork 4025, resulting in high strength and structural stability of the swing arm 402. All connecting joints 404 are connected to the inside of the fixed fork 4025, which helps to prevent the connecting joints 404 from separating from the swing arm 402 and enhances the connection stability between the connecting joints 404 and the swing arm 402.

[0054] Based on the above technical solution, the first connecting arm 407 further includes a crank arm 4071, with a first connecting fork 4072 and a first connecting sleeve 4073 at each end. The crank arm 4071 can be arc-shaped, L-shaped, or other shapes, ensuring that the two ends of the first connecting arm 407 can form a stable connection with the corresponding steering joint 4032 and the second connecting arm 408. The first connecting fork 4072 is rotatably connected to the second rotating part 406 via a second rotating shaft 4076. To reduce wear, preferably, a second bearing 410 is installed inside both the first rotating part 405 and the second rotating part 406. The first rotating part 405 is connected to the first rotating shaft 4027 via a corresponding second bearing 410, and the second rotating part 406 is connected to the second rotating shaft 4076 via a corresponding second bearing 410. One end of the second connecting arm 408 passes through the first connecting sleeve 4073, and the second connecting arm 408 is rotatably connected to the first connecting sleeve 4073. To reduce wear, preferably, a third bearing 4074 is installed inside the first connecting sleeve 4073, and the first connecting sleeve 4073 is connected to the second connecting arm 408 through the third bearing 4074. To enhance the stability of the connection, multiple third bearings 4074 can be installed at intervals inside the first connecting sleeve 4073, and adjacent third bearings 4074 are positioned at intervals by spacer sleeves 4075. Since the second rotating part 406 is rotatably connected to the inner side of the first connecting fork 4072 through the second rotating shaft 4076, the connecting joint 404 is not easily disengaged from the first connecting fork 4072, thereby enhancing the stability between the connecting joint 404 and the first connecting arm 407.

[0055] Based on the above technical solution, the second connecting arm 408 further includes an adjusting shaft 4081 and a second connecting sleeve 4082. One end of the adjusting shaft 4081 passes through the first connecting sleeve 4073, and the adjusting shaft 4081 is rotatably connected to the first connecting sleeve 4073. Specifically, one end of the adjusting shaft 4081 is installed in a third bearing 4074, and is rotatably connected to the first connecting sleeve 4073 through the third bearing 4074. The other end of the adjusting shaft 4081 passes through the second connecting sleeve 4082, and the adjusting shaft 4081 is threadedly connected to the second connecting sleeve 4082. A second connecting fork 4083 is fixedly connected to the end of the second connecting sleeve 4082 away from the adjusting shaft 4081. A third rotating shaft 4084 is installed inside the second connecting fork 4083, and the third rotating shaft 4084 is rotatably connected to the steering head 409. This is to prevent the adjusting shaft 4081 from rotating relative to the second connecting sleeve 4082, which could cause the adjusting shaft 4081 to detach from the second connecting sleeve 4082. Preferably, a locking nut 4085 is threaded onto the adjusting shaft 4081, which abuts against the second connecting sleeve 4082.

[0056] By adopting the above technical solution, since the second connecting sleeve 4082 and the adjusting shaft 4081 are threadedly connected, the length of the second connecting arm 408 can be adjusted by rotating the adjusting shaft 4081, thereby compensating for part machining errors, assembly errors, and adjusting the toe-in. The rotatable connection between the first connecting sleeve 4073 and the adjusting shaft 4081 facilitates shaft rotation and allows relative rotation between the front wheel and the first connecting arm 407 during steering, making the front wheel steering more flexible and preventing jamming.

[0057] To facilitate turning the adjusting shaft 4081 when adjusting the length of the second connecting arm 408, preferably, a hexagonal head 4086 is fixedly connected to the adjusting shaft 4081, with the hexagonal head 4086 located between the lock nut 4085 and the first connecting sleeve 4073. When adjusting the length of the second connecting arm 408, the hexagonal head 4086 is turned using a wrench or other tool, thereby turning the adjusting shaft 4081, providing a stable point of force for the wrench and facilitating the adjustment of the length of the second connecting arm 408.
