Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, and in particular to a motorcycle stand. Background Technology

[0002] As a core support component when a motorcycle is parked, the stand-up stand plays a crucial role: it not only ensures that the vehicle remains upright and stable when parked, preventing tipping due to uneven road surfaces or a shift in the center of gravity, but also provides a solid support base for vehicle maintenance and repair (such as changing tires, cleaning the chain, changing the oil, etc.), making it a key component for improving the safety and convenience of using a motorcycle.

[0003] In the existing technology, some motorcycles (such as the CFMoto 700MT) are not equipped with a main stand from the factory and rely only on the side stand for support, which has significant shortcomings: First, the parking stability is poor, especially in complex scenarios such as slopes and unpaved roads, the vehicle is prone to tilting or even falling over due to uneven force, increasing the risk of vehicle damage; Second, the lack of fixed support points makes the vehicle shake during routine maintenance and repair, which is inconvenient to operate and poses safety hazards.

[0004] Utility model patent CN208021585U discloses a motorcycle stand. By incorporating a left support plate, a right support plate, and a reinforcing beam, and employing a one-piece molded main load-bearing component and welded auxiliary parts, it improves the overall rigidity and support strength of the stand, thus addressing to some extent the problems of concentrated stress and easy frame damage associated with traditional stand designs. However, this device still has room for improvement: its structural design is not optimized for specific motorcycle models (such as the CFMoto 700MT), requiring additional adjustments to the frame during installation, resulting in insufficient versatility and specialization; furthermore, it fails to consider details such as metal-to-metal contact noise and spring protection, leaving room for improvement in user experience.

[0005] Therefore, developing a dedicated support frame for specific vehicle models (such as the CFMoto 700MT) is a pressing technical problem that needs to be solved. It must have sufficient strength and stability to address the lack of a support frame in the original equipment manufacturer (OEM) model, while also optimizing structural details to avoid problems such as abnormal noise and complex installation in existing technologies.

[0035] Figure 1 This is a schematic diagram of a motorcycle stand according to an embodiment of this application, as shown below. Figure 1 As shown, in this embodiment, the main support includes a main support body 1, a reinforcing rib assembly 2, a footrest 3, a ground support foot 4, a connecting plate 5, a height limiting bracket 6, a shock-absorbing assembly 7, a connecting assembly 8, and an elastic support and limiting assembly 9. The bottom ends of the main support body 1 are fixedly connected to the ground support foot 4. The footrest 3 is fixed to the side of the main support body 1. The connecting plate 5 is fixed to the top of the main support body 1 via the connecting assembly 8. The height limiting bracket 6 is installed and fixed on the connecting plate 5. The shock-absorbing assembly 7 is assembled at the rear end of the height limiting bracket 6. The elastic support and limiting assembly 9 is connected to the main support body 1 and the connecting plate 5.

[0036] Figure 2 This is a partial cross-sectional schematic diagram of a motorcycle stand according to an embodiment of this application, as shown below. Figure 2 As shown, in this embodiment, the main support 1 includes a first support 11, a second support 12, a third support 13, and a fourth support 14. The reinforcing rib assembly 2 includes a first reinforcing rib 21, a second reinforcing rib 22, and a third reinforcing rib 23. The two ends of the first support 11 are fixedly connected to the middle of the second support 12 and the third support 13, respectively. At the lower end of the connection between the first support 11 and the second support 12 and the third support 13, the first reinforcing rib 21 and the second reinforcing rib 22 are fixed, respectively, to enhance the structural strength of the connection and prevent deformation caused by stress concentration.

[0037] One end of the fourth bracket 14 is fixed to the lower end of the second bracket 12, and the other end is fixedly connected to the foot 3. The third reinforcing rib 23 is fixed to the upper end of the connection between the fourth bracket and the second bracket. The lower end of the third bracket 13 is provided with a boss 132, and a pin hole is opened on the boss 132 for connecting the elastic support and the limiting component 9. The bottom ends of the second bracket 12 and the third bracket 13 are fixedly connected to the ground support foot 4, and one end of the ground support foot 4 is bent upward.

[0038] In practical applications, the main body 1 of the support is entirely made of seamless steel pipe with a wall thickness of 2 mm and a No. 20 gauge. Seamless steel pipe with a No. 20 gauge has excellent mechanical properties, and its wall thickness design ensures that the structural strength is sufficient to support the weight of the entire vehicle while controlling the weight of the component, thus achieving a balance between strength and lightweight.

[0039] According to the optional example, in this embodiment, the reinforcing rib assembly 2 adopts a hollow structure design, which reduces the amount of material used without reducing the strength, and further achieves the weight reduction goal.

[0040] Figure 3 This is a schematic diagram of the structure of the left connecting plate of a motorcycle stand according to an embodiment of this application, as shown below. Figure 3As shown, in this embodiment, the lower end of the left connecting plate 51 is provided with a first groove 511 that matches the left connecting point 121. The groove structure enables precise positioning with the main body 1 of the large support, ensuring structural consistency after assembly. The left connecting plate 51 is also provided with fastening holes for connection with the vehicle body bracket.

[0041] Figure 4 This is a first partial schematic diagram of a motorcycle stand according to an embodiment of this application, as shown below. Figure 4 As shown, in this embodiment, the lower end of the left connecting plate 51 is fixedly connected to the left connecting point 121 by a fastener 83. An aluminum sleeve 81 is sleeved on the outer periphery of the fastener 83. Grooves are symmetrically opened on the outer periphery of the aluminum sleeve 81, and nitrile O-rings 82 are assembled in the grooves.

[0042] Figure 5 This is a second partial schematic diagram of a motorcycle stand according to an embodiment of this application, as shown below. Figure 5 , Figure 2 As shown, in this embodiment, the shock absorption component includes a shock absorption pad 71 and a nut 72. The height limiting bracket 6 is fixedly connected to the left side of the left connecting plate 51 through the first fastening hole 512 and the second fastening hole 513 using fasteners. A nut 72 with a shock absorption pad 71 is installed in the through hole behind it.

[0043] In practical applications, the height limiting bracket 6 is processed using laser cutting integrated molding technology, and the fasteners connected to the left connecting plate 51 are made of high-grade carbon steel screws to ensure that the height limiting bracket will not loosen due to stress or environmental corrosion during long-term use, accurately limiting the maximum support height of the large support and avoiding vehicle body tilting or structural damage caused by excessive support.

[0044] Figure 6 This is a schematic diagram of the structure of the right connecting plate of a motorcycle stand according to an embodiment of this application, as shown below. Figure 6 As shown, in this embodiment, the lower end of the right connecting plate 52 is provided with a second groove 521 that matches the right connecting point, and the groove enables precise assembly with the main body 1 of the large support; the right connecting plate 52 is also provided with a pin hole 522 and a hole 523.

[0045] Figure 7 This is a third partial schematic diagram of a motorcycle stand according to an embodiment of this application, as shown below. Figure 7 As shown, in this embodiment, the lower end of the right connecting plate 52 is fixedly connected to the right connecting point 131 by fastener 83. An aluminum sleeve 81 is also sleeved on the outer periphery of the fastener 83. A nitrile O-ring 82 is assembled in the groove on the outer periphery of the aluminum sleeve 81, which can realize flexible connection and avoid metal contact noise. The elastic support and limiting component 9 is connected to the right outer side of the right connecting plate 52 through the pin hole 522 to ensure the effective transmission of elastic force.

[0046] In practical applications, the connecting plate 5 is made of 45# steel casting. 45# steel has high strength and hardness, and the casting process can achieve one-piece molding of complex structures, ensuring that the connecting plate will not deform or break during the process of bearing the weight of the vehicle body and transmitting forces.

[0047] According to the optional example, in this embodiment, the aluminum sleeve 81 can avoid direct metal contact between the fastener and the connecting plate and the main support body, reducing wear; the nitrile O-ring 82 has good elasticity and wear resistance, which can buffer the vibration of the connection part, eliminate the abnormal noise generated by metal friction, and at the same time enhance the sealing of the connection, prevent dust and moisture from entering the connection part and causing corrosion, and improve the service life of the component.

[0048] Figure 8 This is a fourth partial schematic diagram of a motorcycle stand according to an embodiment of this application, as shown below. Figure 8 As shown, in this embodiment, the upper and lower ends of the spring 91 of the elastic support and limiting component 9 are respectively connected to and installed in the through holes of the first fixing plate 92 and the second fixing plate 93. The first fixing plate 92 is installed in the pin hole 522 of the right connecting plate 52 by a pin 94, and the second fixing plate 93 is fixed to the boss 132 by a pin.

[0049] According to an optional example, in this embodiment, the setting of hole 523 provides convenient operating space for the installation of spring 91, making it easy to hook the spring onto the pin 94 of the bracket using a tool.

[0050] The center points of the first fixing plate 92 and the second fixing plate 93 correspond to the pins 94 of the main support bracket and the side plate bracket, respectively, to ensure that the force direction of the spring 91 after installation is consistent with the movement trajectory of the main support, so as to realize linear force transmission and avoid structural damage or operation jamming caused by force deviation.

[0051] In practical applications, a protective cover can be added to the outside of the spring 91. The protective cover is made of wear-resistant material, which can effectively prevent the spring from direct contact with cycling boots and other parts during riding, prevent the spring from scratching the cycling boots or clothing, and reduce the friction between the spring and external debris, thus extending the service life of the spring.

[0052] It should be noted that the overall structure of the left connecting plate 51 and the right connecting plate 52 is exactly the same, with differences only in functional adaptation details. Both have grooves at their lower ends that adapt to the connection points of the main support frame (the left connecting plate 51 has the first groove 511, and the right connecting plate 52 has the second groove 521), and their connection method with the main support frame is the same, both being fixed by high-strength carbon steel fasteners. The difference lies in that the left connecting plate 51 is equipped with a height limiting bracket 6 on its left side, while the right connecting plate 52 is connected to the elastic support and limiting component 9.

[0053] Figure 9This is a fifth partial schematic diagram of a motorcycle stand according to an embodiment of this application, as shown below. Figure 9 As shown in this embodiment, the first reinforcing rib 21 is designed with a side support limiting point 211. The side support limiting point 211 can limit the rotation angle of the side support, ensuring that the side support can stably support the vehicle body when it is deployed and will not interfere with other components when it is retracted.

[0054] In practical applications, the surfaces of exposed components such as the main support body 1 and connecting plate 5 are all treated with automotive-grade powder coating, which effectively resists rainwater, dust and ultraviolet radiation from the external environment, and prevents the components from rusting or peeling off.

[0055] The application principle of the large support in this embodiment of the utility model is as follows:

[0056] First, fix the connecting plate 5. Secure the left connecting plate 51 and the right connecting plate 52 to the outer side of the original motorcycle bracket plate using high-strength fasteners. Next, assemble the main support body 1 and the connecting plate 5. Insert the aluminum sleeve 81 with the nitrile O-ring 82 into the left connection point 121 and the right connection point 131 of the main support body 1, respectively. Use fasteners 83 to pass through the connection points between the connecting plate 5 and the main support body 1 to complete the fixation. Finally, install the elastic support and limiting assembly 9. Hang one end of the spring 91 on the through hole of the first fixing plate 92 and the other end on the through hole of the second fixing plate 93. Use a tool to pass through the hole 523, stretch the spring 91, and hang the first fixing plate 92 on the corresponding pin 94. The second fixing plate 93 is fixed to the boss 132 of the main support body 1 by the pin.

[0057] When parking support is needed after installation, the user stands to the side of the motorcycle, pressing down on foot pedal 3. The pedaling force is transmitted to the main support body 1 through the fourth bracket 14, causing the main support body 1 to rotate clockwise around the connection points of the left connecting plate 51, the right connecting plate 52, and the main support body 1. As the main support body 1 rotates, the ground support feet 4 at the bottom of the second bracket 12 and the third bracket 13 gradually contact the ground, while the spring 91 of the elastic component is stretched, storing elastic potential energy. When the main support body 1 rotates to an angle where the motorcycle is upright, the height limiting bracket 6 contacts the preset limiting surface of the motorcycle, limiting the main support body 1 from continuing to rotate and preventing over-support; the shock-absorbing pad 71 buffers the impact force during this process, ensuring stable support.

[0058] When the stand needs to be folded up in preparation for riding, the user lifts the rear of the motorcycle upwards or lightly presses the upper end of the foot pedal 3 in the opposite direction, causing the stand body 1 to rotate counterclockwise around the connection point. At this time, the stretched spring 91 releases its elastic potential energy, helping to reduce the force required for operation. During the folding process, the side stand limit point 211 on the first reinforcing rib 21 restricts the rotation of the side stand, preventing the side stand from colliding with the stand body 1; the nitrile O-ring 82 of the connecting component 8 can buffer vibration, making the folding action smoother, and finally the stand body 1 fits snugly under the motorcycle, without affecting riding.

[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
