Technical Field

[0001] This utility model relates to a portable road vehicle support frame. Background Technology

[0002] Traditional road bikes, in pursuit of ultimate lightweight and aerodynamic performance, generally eliminate kickstand mounting holes and kickstands. While achieving a slim, rigid frame, this sacrifices parking convenience. In recent years, road bikes have rapidly expanded from racing tracks to urban commuting and recreational cycling, leading to a surge in parking demands. Bikes without kickstands can only be leaned against walls or placed on their sides on hard surfaces like shopping districts and subway entrances, easily scratching the frame, drivetrain, and wheelset, and obstructing traffic, becoming a new pain point for urban cycling.

[0003] Parking road bikes has always been a challenge. Besides leaning against walls or lying on their sides, bike stands can be used for support. However, existing bike stands are not portable and have limited functionality. Therefore, there is an urgent need for a lighter, faster, and more versatile portable road bike stand.

[0010] Furthermore, the integrated support-container frame and the fixed base are provided with a snap-fit ​​connection structure, with the connection direction perpendicular to the seat tube axis of the frame, in order to reduce the risk of loosening caused by riding vibration.

[0011] Furthermore, the snap-fit ​​connection structure consists of a fixed base slot on the fixed base and a support frame slot on the integrated support-container frame. The two slots have complementary shapes and can be quickly inserted and removed.

[0012] Furthermore, in the first working position, the upper part of the integrated support-container frame is provided with a foot pedal support opening for fitting with the central axis of the road vehicle's foot pedal to form a temporary parking fulcrum.

[0013] Furthermore, in the second working position, the upper part of the integrated support-container frame is provided with a water cup fixing wing and a base, which together define the container holding space for placing water cups.

[0014] Furthermore, the container's accommodating space sidewalls and bottom surfaces are provided with polygonal and triangular perforated structures to reduce weight and improve clamping stability.

[0015] Furthermore, the integrated support-container frame is a single-unit structure, with the upper part integrating the container holding space and the lower part integrating the support contact part.

[0016] Furthermore, the mounting base is provided with mounting holes for bolt connection with the seat tube of a road vehicle, enabling quick assembly and disassembly.

[0017] Furthermore, the fixed base and the integrated support-container frame adopt a slanted groove friction-assisted buckle to improve the connection reliability.

[0018] Furthermore, the material of the integrated support-container frame is engineering plastic or fiber-reinforced composite material, which balances lightweight and structural strength.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0026] like Figure 1 and Figure 4 As shown, the integrated support-container frame 2 is a single structure, which is equipped with a foot support port 201, a support frame slot 202, a water cup fixing wing 203 and a base 204. The material of the integrated support-container frame 2 is engineering plastic or fiber reinforced composite material, which takes into account both lightweight and structural strength.

[0027] In one embodiment, when the support frame is in the second working position, the support-container integrated frame 2 is fixed to the vehicle frame and away from the ground. The cup fixing wing 203 and the base 204 together define the container holding space for placing the cup 3. The container holding space has perforations distributed on the side wall and bottom surface to reduce weight and improve clamping stability.

[0028] Furthermore, the integrated support-container frame is constructed using FAD 3D printing technology, layer by layer, depositing and melting ABS filaments to form a single piece with a wall thickness of 1.2 mm. Key load-bearing areas are equipped with local reinforcing ribs with a thickness of 2 mm, and the weight of a single piece is controlled at 34 g. The upper water cup holding area is triangularly hollowed out, and the side walls and bottom surface are evenly distributed with polygonal hollow holes, which takes into account both weight reduction and drainage. The upper support area is equipped with a semi-circular foot pedal support opening, with a contact length of ≥12 mm with the pedal axle and a contact surface radius of 9 mm, which is compatible with most standard road bike pedals. The entire bike can stand stably on hard surfaces such as asphalt, ceramic tiles, and wooden boards without slipping in wind level 4.

[0029] like Figure 2 and Figure 3 As shown, the mounting base 1 is detachably mounted on the road bike frame. It has a mounting hole 101 and a mounting base slot 102. The mounting hole 101 is used to bolt to the road bike seat tube 4 to achieve quick assembly and disassembly.

[0030] A snap-fit ​​connection structure is provided between the integrated support-container frame 2 and the fixed base 1, with the connection direction perpendicular to the seat tube axis of the frame to reduce the risk of loosening caused by riding vibrations. This snap-fit ​​connection structure consists of a fixed base slot 102 and a support frame slot 202. The fixed base slot 102 has a trapezoidal structure, and the two slots have complementary shapes and can be quickly inserted and removed. Furthermore, both the fixed base 1 and the integrated support-container frame 2 use angled groove friction-assisted snap-fit, improving connection reliability.

[0031] Furthermore, the front of the mounting base has a pre-drilled M5 through hole. After inserting the standard road bike seatpost bolt, tightening it with a torque of 2 N·m completes the rigid connection with the frame. The back is designed with a 0.2 mm deep positioning platform, which can embed 3M VHB double-sided adhesive pads to assist in positioning and absorb micro-vibrations, preventing bolt loosening. The mounting base has symmetrical trapezoidal cross-section slots on both sides, with a micro-arc radius of 0.5 mm at the bottom and a depth of 10 mm. The inlet is flared to guide the quick insertion of the integrated frame.

[0032] Furthermore, the buckle engagement direction is perpendicular to the seat post axis, and the trapezoidal inclined surface generates an insertion force of 20-25 N and a pull-out force of 60-70 N, with almost zero vibration shear force in the riding direction; the buckle contact surface can also be equipped with a 0.2 mm high micro-convex rib and a 0.5 mm thick TPU damping pad to eliminate high-frequency resonance noise.

[0033] In one embodiment, such as Figure 5 As shown, when the support frame is in the first working position, the lower part of the integrated support-container frame 2 forms ground contact with the vehicle frame to stably support the vehicle in a parked state; the foot pedal support opening 201 provided on the upper part of the integrated support-container frame 2 is used to fit with the central axis of the road vehicle foot pedal to form a temporary fulcrum.

[0034] This utility model is not limited to the specific embodiments described above. Those skilled in the art to which this utility model pertains may make various modifications, additions, or similar substitutions to the described specific embodiments, provided that such modifications or additions do not depart from the spirit of this utility model or exceed the scope defined by the appended claims, all of which are within the protection scope claimed by this utility model.
