Description

Technical Field

[0001] This utility model relates to bicycle support components, and more particularly to a bicycle support stand. Background Technology

[0002] 1. Chinese Patent Publication No. CN206766192U discloses a multi-functional bicycle parking support stand, which includes an upper support frame, a middle support frame, and a lower support stand connected together; the upper support frame and the middle support frame are connected by a rotator, and the middle support frame and the lower support stand are connected by a bidirectional ratchet-controlled rotator, wherein the bidirectional ratchet-controlled rotator is composed of a ratchet in the center of the housing and an operating valve that are movably connected by a spring.

[0003] The aforementioned multi-functional bicycle parking support stand is made of metal, making it relatively heavy and somewhat complex in structure.

[0004] 2. Most bicycle kickstands are now of fixed length. However, bicycles of the same size may have tires of different diameters. Fixed-length kickstands are not long enough for large-diameter tires. After installation, the bicycle will tilt too much when parked, making it easy for the bicycle to tip over.

[0005] 3. If the entire support leg of a bicycle kickstand is made of carbon fiber, and the adjusting screw is too stiff, the carbon fiber itself is brittle. When directly screwing the carbon fiber support leg to the adjusting screw, the support leg is easily damaged, making it impossible to tighten properly. Even if temporarily tightened, after a period of use, the carbon fiber support leg will wear down from the adjusting screw and become untight. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a bicycle support frame with a reasonable structural design. It uses a lightweight support rod made of carbon fiber material, and a metal top component is fixedly connected to the top of the carbon fiber support rod, thereby ensuring the installation firmness and stability of the carbon fiber support rod. Different height and low position holes are opened on the side wall of the bottom section of the hinge seat to adjust the extension and retraction of the carbon fiber support rod and the metal top component.

[0007] The solution to the above technical problem is as follows: A bicycle support stand includes a mounting base, a hinged base, a support leg, and an adjusting screw. The bottom section of the mounting base is hinged to the hinged base, and the support leg is a carbon fiber support leg. The bottom section of the hinged base has a height adjustment through hole for the leg, and the side wall of the bottom section of the hinged base has at least two height adjustment holes that connect to the height adjustment through hole. A metal top component is fixedly connected to the top of the carbon fiber support leg, and the side wall of the metal top component has a screw hole. The top section of the carbon fiber support leg and the metal top component are inserted into the height adjustment through hole and fit perfectly. The carbon fiber support leg and the metal top component are telescopically adjusted in height through the height adjustment through hole. After the screw hole is aligned with the corresponding height adjustment hole, the adjusting screw is inserted through the corresponding height adjustment hole and the screw hole to fix the height of the carbon fiber support leg.

[0008] The carbon fiber support rod has a core hole in the middle of its top end. The metal top component is integrally formed and includes an upper metal section and a lower metal section. The upper metal section is larger than the lower metal section, and the circumferential shape of the upper metal section is consistent with the circumferential shape of the carbon fiber support rod. The lower metal section is inserted into the core hole for fixed connection, and the side wall of the upper metal section has screw holes.

[0009] The carbon fiber support leg is circular; the core hole is circular; the metal top component is circular; there is a metal ring step between the upper and lower sections of the metal component; the diameter of the upper section of the metal component is the same as the diameter of the carbon fiber support leg; the top section of the carbon fiber support leg is pressed against the metal ring step for fixation.

[0010] The metal top component is made of aluminum alloy or titanium alloy; the bottom of the carbon fiber support rod is fixed with a foot pad.

[0011] The hinge seat includes an upper connector, a long tube column, an angle limiting component, and a pressure spring. The upper connector and the long tube column are integrally formed. The upper connector has a fork opening in the axial direction. The left and right sides of the fork opening are front connecting lugs and rear connecting lugs. The front connecting lugs and the rear connecting lugs have corresponding left and right lug holes. The fork opening is U-shaped. A stop component is fixed inside the middle section of the long tube column. The pressure spring is inserted into the tube hole at the bottom of the fork opening. The angle limiting component is T-shaped. The lower vertical section of the angle limiting component is inserted into the middle of the pressure spring. The mounting base includes an upper section plate and a lower section plate, with a bend between them. The lower section plate has bolt holes. The bottom edge of the lower section plate has an integrally formed bottom straight edge, and one side has an integrally formed right straight edge. A lower right arc edge is integrally formed between the bottom straight edge and the right straight edge. A lower left limiting angle is integrally formed at the left end of the bottom straight edge, and a upper right limiting angle is integrally formed at the upper right corner of the right straight edge. A pressure spring is inserted from the fork into the upper section of the long pipe column and presses against the stop. The lower section plate is inserted into the fork, and the angle limiting member... The top horizontal piece is inserted into the bottom straight edge of the lower section plate. The left and right support ears and bolt holes are connected to the bolt assembly. The angle limiting piece is elastically pressed against the lower section plate by a pressure spring. The hinge seat can rotate up and down relative to the mounting seat on the right side. When the left corner of the angle limiting piece presses against the lower left limit angle, the hinge seat rotates down and stops rotating, and is fixed by elastic pressing with a pressure spring. When the right corner of the angle limiting piece presses against the upper right limit angle, the hinge seat rotates up and down to the right and stops rotating, and is fixed by elastic pressing with a pressure spring.

[0012] The hinge seat can be rotated up and down on the right side relative to the mounting seat at an angle within 100 degrees.

[0013] The hinge seat is made of aluminum alloy or titanium alloy; the mounting seat is made of aluminum alloy or titanium alloy; the angle limiting component is made of aluminum alloy or titanium alloy.

[0014] The upper section plate and / or the lower section plate are provided with through holes.

[0015] The bending angle between the upper and lower sections is between 100 and 135 degrees.

[0016] The middle section of the long tubular column is fixed with a stop.

[0017] The advantages of this bicycle support stand are as follows: 1. The product uses lightweight carbon fiber support legs, reducing the overall weight of the bicycle support stand. A metal top component is fixedly connected to the top of the carbon fiber support leg. The metal top component and adjusting screw are easily tightened without being damaged, and the tightening force is better, ensuring a secure and stable installation of the carbon fiber support leg. Different height adjustment holes are provided on the side wall of the bottom section of the hinge seat to adjust the extension and retraction of the carbon fiber support leg and metal top component, adapting to different diameter tires of the same size bicycle, so that the bicycle tilts to the left at a moderate angle after parking, resulting in a more stable stop. 2. The metal top component, mounting base, and hinge seat are made of aluminum alloy or titanium alloy, further reducing weight. 3. The specific hinged joint structure between the mounting base and the hinge seat enables stable switching between the bicycle's active and stationary states. Attached Figure Description

Detailed Implementation

[0032] like Figures 1-13The bicycle kickstand includes a mounting base 1, a hinged base 2, a support leg 3, and an adjusting screw 4. The adjusting screw 4 is made of metal. The mounting base 1 is fixedly installed on the bottom of the left middle section of the bicycle frame or the left rear section of the bicycle frame via a screw assembly. The bottom section of the mounting base 1 is hinged to the hinged base 2 to facilitate parking and fixing the bicycle or flipping the hinged base 2 and support leg 3 open for riding. The support leg 3 is a carbon fiber support leg 3, which is lighter and reduces the weight of the bicycle kickstand. The bottom section of the hinged base 2 has an axially oriented footrest hole 2A for adjusting the height of the leg. The side wall of the bottom section of the hinged base 2 has at least two height adjustment holes 2B that connect the height adjustment of the leg. The rod insertion hole 2A and the height adjustment hole 2B generally have three positions to better adapt to the actual needs of users and correct for size errors of different brands of bicycles. The distance between the height adjustment holes 2B is 1 cm to 2 cm, preferably 1.5 cm. The top of the carbon fiber support rod 3 is fixedly connected to a metal top component 5. The side wall of the metal top component 5 has a screw hole 51. The tightness between the metal top component 5 and the adjusting screw 4 is not easily worn or stripped, and can be adjusted by tightening multiple times. The top section of the carbon fiber support rod 3 and the metal top component 5 are inserted into the height adjustment rod insertion hole 2A of the rod and fit perfectly without being too loose. The carbon fiber support rod 3 and the metal top component 5 extend and retract in the height adjustment rod insertion hole 2A of the rod. For low adjustment, after aligning screw hole 51 with the corresponding high / low gear hole 2B, use adjusting screw 4 to fix the height of carbon fiber support leg 3 by passing it through the corresponding high / low gear hole 2B and screw hole 51; for example 1: after aligning screw hole 51 with the corresponding first-gear high / low gear hole 2B, use adjusting screw 4 to fix the height of carbon fiber support leg 3 by passing it through the corresponding first-gear high / low gear hole 2B and screw hole 51; for example 2: after aligning screw hole 51 with the corresponding second-gear high / low gear hole 2B, use adjusting screw 4 to fix the height of carbon fiber support leg 3 by passing it through the corresponding second-gear high / low gear hole 2B and screw hole 51; this product uses a lighter carbon fiber support leg 3 to reduce the weight of the bicycle support leg; because The adjusting screw 4 is hard, while the carbon fiber is not as hard and is relatively brittle. When the carbon fiber support leg 3 is directly screwed to the adjusting screw 4 for adjustment, the carbon fiber support leg 3 is easily damaged by the adjusting screw 4 and cannot be tightened properly. Even if it is temporarily tightened, the carbon fiber support leg 3 will be worn down by the adjusting screw 4 after a period of use and cannot be tightened again. Therefore, a metal top part 5 is fixedly connected to the top of the carbon fiber support leg 3. The metal top part 5 has the same or nearly the same hardness as the adjusting screw 4. The metal top part 5 and the adjusting screw 4 are not easily damaged by repeated adjustments and have better tightening force. When tightened properly, it will not be loose, thus ensuring the installation firmness and stability of the carbon fiber support leg 3.For bicycles of the same size, some tires have smaller diameters than others. Using a uniform bicycle kickstand of the same length is suitable for smaller diameter tires, but for larger diameter tires, the kickstand becomes too short, making the bicycle lean too far to the left when parked and prone to tipping over. Therefore, different height-adjustable holes 2B are created on the side wall of the bottom section of the hinge 2 to allow for the extension and retraction adjustment of the carbon fiber support leg 3 and the metal top component 5. This accommodates tires of different diameters on bicycles of the same size, ensuring a moderate leftward tilt and greater stability when parked. Alternatively, the height-adjustable holes 2B are plugged with rubber to prevent mud and sand from entering and for aesthetic purposes.

[0033] Preferably, the carbon fiber support rod 3 has a core hole 31 at the top center, and the metal top component 5 is integrally formed. The metal top component 5 includes an upper metal section 5A and a lower metal section 5B. The upper metal section 5A is larger than the lower metal section 5B, and the circumferential shape of the upper metal section 5A is consistent with the circumferential shape of the carbon fiber support rod 3. The lower metal section 5B is inserted into the core hole 31 for fixed connection and anti-detachment. They are reinforced with adhesive to prevent detachment. The side wall of the upper metal section 5A has a screw hole 51. The above structure further refines the connection structure between the carbon fiber support rod 3 and the metal top component 5. This structure makes the connection between the metal top component 5 and the carbon fiber support rod 3 more stable and avoids stress concentration that could cause the carbon fiber layer to peel or crack. At the same time, the outer diameter of the upper metal section 5A matches that of the carbon fiber support rod 3, maintaining the consistency of the overall shape and size, and preventing loose insertion into the rod height adjustment hole 2A.

[0034] The carbon fiber support rod 3 is circular; the rod core hole 31 is circular; the metal top component 5 is circular, and there is a metal surrounding step 5C between the upper section 5A and the lower section 5B of the metal component. The diameter of the upper section 5A of the metal component is the same as the diameter of the carbon fiber support rod 3. The top section of the carbon fiber support rod 3 is pressed against the metal surrounding step 5C for fixation, further improving the tightness and stability of the connection. The above design has a simple shape.

[0035] The metal top component 5 is made of aluminum alloy or titanium alloy, which further reduces weight.

[0036] Preferably, the hinge seat 2 includes an upper connector 21, a long tube column 22, an angle limiting member 23, and a pressure spring 24. The upper connector 21 and the long tube column 22 are integrally formed. The size of the upper connector 21 is larger than that of the long tube column 22 to increase the area. The upper connector 21 has an axially formed fork 25. The left and right sides of the fork 25 are front connecting lugs 26 and rear connecting lugs 27. The front connecting lugs 26 and rear connecting lugs 27 have corresponding left lug holes 261 and right lug holes 271. The right support ear hole 271 is flat, the fork 25 is U-shaped, and a stop 28 is fixed inside the middle section of the long tube column 22. The stop 28 is used to press the pressure spring 24. The pressure spring 24 is made of steel. The pressure spring 24 is inserted into the tube hole at the bottom of the fork 25 and presses against the stop 28 for fixation. The angle limiting member 23 is T-shaped. The lower vertical section of the angle limiting member 23 is inserted into the middle of the pressure spring 24 for positioning and fixation. The left and right corners of the T-shaped angle limiting member 23 are slightly raised. The mounting base 1 is integrally formed, resulting in high production efficiency. The mounting base 1 includes an upper section plate 11 and a lower section plate 12. The upper section plate 11 and the lower section plate 12 are bent together. The lower section plate 12 has bolt holes 121. The bottom edge of the lower section plate 12 has an integrally formed bottom straight edge 122, and one side has an integrally formed right straight edge 123. A right lower arc-shaped edge 124 is integrally formed between the bottom straight edge 122 and the right straight edge 123. The right lower arc-shaped edge 124 smoothly transitions with the angle limiting member 23 during the flipping process. The left end of the bottom straight edge 122 has an integrally formed left lower limiting angle 125, and the upper right corner of the right straight edge 123 has an integrally formed right upper limiting angle 126. A pressure spring 24 is inserted from the fork 25 into the upper section hole of the long pipe column 22 and presses against the stop member 28. The lower section plate 12 is inserted into the fork 25. The angle limiting member 23 fits perfectly. The top horizontal piece of the angle limiting member 23 is inserted into the bottom straight edge 122 of the lower section plate 12. The left support ear hole 261, the right support ear hole 271, and the bolt hole 121 are connected to the bolt assembly 29, so that the mounting seat 1 is movably hinged to the fork 25. The angle limiting member 23 is elastically pressed against the lower section plate 12 by the pressure spring 24. The hinge seat 2 can rotate and move up and down relative to the mounting seat 1 on the right side. The carbon fiber support rod 3 rotates and moves with the hinge seat 2. When the left corner of the angle limiting member 23 presses against the lower left limiting angle 125, the hinge seat 2 rotates and moves down and stops, and is elastically pressed and fixed by the pressure spring 24. When the right corner of the angle limiting member 23 presses against the upper right limiting angle 126, the hinge seat 2 rotates and moves up and down to the right and stops, and is elastically pressed and fixed by the pressure spring 24.

[0037] When the hinge seat 2 flips and moves relative to the mounting seat 1 from the upper right to the lower left, the carbon fiber support leg 3 flips and moves with the hinge seat 2. When the left corner of the angle limiting member 23 presses against the lower left limiting angle 125, the downward flipping and moving of the hinge seat 2 is stopped and it is elastically pressed and fixed by the pressure spring 24 to prevent the hinge seat 2 and the carbon fiber support leg 3 from moving naturally. The hinge seat 2 and the carbon fiber support leg 3 are in a vertical state, which is the bicycle support leg supporting the bicycle in a stationary state. When the hinge seat 2 flips and moves relative to the mounting seat 1 from the lower left to the upper right, the carbon fiber support leg 3 flips and moves with the hinge seat 2. When the right corner of the angle limiting member 23 presses against the upper right limit angle 126, the flipping and moving of the hinge seat 2 to the upper right is stopped and it is elastically pressed and fixed by the pressure spring 24 to prevent the hinge seat 2 and the carbon fiber support leg 3 from moving naturally and falling down. The hinge seat 2 and the carbon fiber support leg 3 are in a horizontally straight state, which means that the bicycle support leg is not supporting the bicycle and the bicycle can be ridden. The above describes the specific structure of mounting base 1 and hinge base 2, which enables stable switching of the support frame between the bicycle's use state and the stationary state. The structure is compact and the operation is smooth. The angle limiting component 23 always maintains tight elastic compression contact with the limiting angle under the elastic preload of the pressure spring 24, ensuring the positioning reliability of the two limiting angles and preventing the hinge base 2 and carbon fiber support rod 3 from moving naturally. The left and right slightly upturned corner design of the T-shaped angle limiting component 23 allows for better insertion and pressing fit between the two limiting angles.

[0038] The hinge seat 2 can be moved and rotated relative to the mounting seat 1 at an angle within 100 degrees, generally 0 degrees to 90 degrees, and a suitable rotation angle can be designed.

[0039] The hinge seat 2 is made of aluminum alloy or titanium alloy to further reduce weight; the mounting seat 1 is made of aluminum alloy or titanium alloy to further reduce weight; the angle limiting member 23 is made of aluminum alloy or titanium alloy to further reduce weight.

[0040] The upper plate 11 and / or the lower plate 12 are provided with through holes 1A to reduce material and further reduce weight.

[0041] The bending angle between the upper plate 11 and the lower plate 12 is between 100 degrees and 135 degrees, generally between 115 degrees and 125 degrees, and a suitable angle is designed.

[0042] The middle section of the long tube column 22 is fixed with a stop 28, which improves stability and makes it easier to design, install, and fix. The stop 28 is made of screws or rivets.

[0043] The bottom of the carbon fiber support leg 3 is fixed with a foot pad 6A. The foot pad is made of aluminum or anti-slip rubber and has a cut surface. The foot pad comes into contact with the ground and rubs against it, which effectively prevents natural slippage and improves the stability of the vehicle when parked. It can reliably support parking under different ground conditions, while avoiding direct wear on the bottom of the carbon fiber support leg 3 and extending its service life.
