Description

Technical Field

[0001] The utility model relates to a universal grafting structure for a reverse tricycle. Background Art

[0002] The reverse tricycle is a tricycle with two front wheels and one rear wheel. It has the advantages of anti-skid, stability and good safety, and is deeply loved by consumers.

[0003] The structure of existing reverse tricycles on the market typically consists of a main frame, a yaw structure mounted on the main frame, two front wheels positioned in the yaw structure, and a rear wheel mounted at the rear end of the main frame. Compared to traditional two-wheeled vehicles, reverse tricycles are more complex and expensive to manufacture. However, they offer improved stability, safety, and a better driving experience. Therefore, how to combine the advantages of reverse tricycles with traditional two-wheeled vehicles while reducing the purchase cost for users has become a pressing technical challenge in the industry. Summary of the Invention

[0004] The utility model aims to solve the existing technical problem by providing a universal grafting structure for a reverse tricycle, which can design the yaw structure of the reverse tricycle into an integral component so that it can be grafted onto any traditional two-wheeled vehicle on the market.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] The utility model discloses a universal grafting structure for reverse tricycles, comprising a yaw structure as an assembly component, wherein the yaw structure is provided with a grafting assembly, and the yaw structure is connected to the main frame of a traditional two-wheeled vehicle through the grafting assembly; the grafting assembly comprises a grafting plate and a plurality of grafting columns, wherein the plurality of grafting columns are fixed on the yaw structure, and the plurality of grafting columns have different lengths, so that the end-to-end connecting lines between the ends of the plurality of grafting columns and the grafting plate form a regular / irregular shape, one side of the grafting plate is fixed to the connecting ends of the plurality of grafting columns, and the other side connected to the grafting columns can be fixed to the main frame.

[0007] The grafting structure of the present invention connects the main frame of a traditional two-wheeled vehicle with the yaw structure through a grafting plate and a plurality of grafting columns. It is only necessary to dismantle the front wheel assembly of the traditional two-wheeled vehicle as a whole, and fix the other side of the grafting plate to the main frame by welding / bolting or other fixing methods, and then fix one side of the grafting plate to the plurality of grafting columns by bolts. Since the lengths of the plurality of grafting columns are different, their connection ends form a regular / irregular shape, which makes the connection strength between the grafting plate and the grafting columns greater and the stability better.

[0008] The yaw structure includes a main beam frame, an upper rocker arm assembly and a lower rocker arm assembly pivotally hingedly arranged on the main beam frame, and the plurality of grafting columns are fixed on the main beam frame.

[0009] There are three grafting columns, namely an upper grafting column, a middle grafting column, and a lower grafting column, which are fixed on the main beam frame at the upper, middle, and lower positions. The length of the middle grafting column is greater than that of the upper grafting column and the lower grafting column, so that the head and tail connecting lines between the connecting ends of the upper grafting column, the middle grafting column, and the lower grafting column form a triangle.

[0010] The connection line of the connection end is three grafting columns of a triangular structure, which makes the connection of the grafting plate relative to the grafting columns more firm and stable, not easy to deform, and highly safe.

[0011] The lower grafting column is arranged on the yaw main beam at the bottom of the main beam frame, and the grafting plate connects the upper grafting column, the middle grafting column and the lower grafting column, thereby making the connection between the yaw main beam and the main beam frame more firm.

[0012] The grafting plate includes a left connecting plate, a right connecting plate and a support plate connected to the upper half of the left connecting plate and the right connecting plate. A spacing space is formed between the left connecting plate and the right connecting plate, and a plurality of connecting pins are provided between the left connecting plate and the right connecting plate; the main frame matches the lower half of the spacing space formed between the left connecting plate and the right connecting plate.

[0013] The grafting plate formed by the combination of the left connecting plate, the right connecting plate and the support plate has a low manufacturing cost and improves its overall strength through a number of connecting pins, meeting the manufacturing requirements of existing vehicles and ensuring safety; the left connecting plate and the right connecting plate with a spacing space can accommodate the main frame, thereby making the welding area between the main frame and the left connecting plate and the right connecting plate larger and the connection more secure.

[0014] The left connecting plate and the right connecting plate are provided with neck grooves at positions on the lower end surfaces of the matching support plates, and the free end of the main frame is located at the neck groove position.

[0015] The design of the neck groove allows for welding space between the free end of the main frame and the lower end surface of the support plate, thereby increasing the connection strength.

[0016] The left connecting plate and the right connecting plate are symmetrically arranged, and the ends thereof butting against the grafting columns are in regular / irregular shapes.

[0017] The regular / irregular shaped front ends of the left and right connecting plates not only reduce material usage and lower costs, but also avoid the related structures of the main beam frame.

[0018] There is at least one connecting pin at the position of the left connecting plate and the right connecting plate between the two adjacent grafting columns.

[0019] The design of the connection pins and bolt intervals further improves the connection strength between the grafting plate and the grafting column.

[0020] In summary, the beneficial effects of the present invention are:

[0021] Compared with the prior art, the universal grafting structure of the reverse tricycle of the utility model realizes the purpose of splicing the yaw structure with the main frame of the traditional two-wheeled vehicle at any time, thereby making the traditional two-wheeled vehicle become a reverse tricycle at a relatively low cost.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0028] See also Figures 1 to 5 The utility model provides a universal grafting structure for reverse tricycles, including a yaw structure as an assembly component, the yaw structure includes a main beam frame 1, an upper rocker arm assembly and a lower rocker arm assembly pivotally hingedly arranged on the main beam frame 1, the upper rocker arm assembly includes a left upper rocker arm 2 and a right upper rocker arm 3, the lower rocker arm assembly includes a left lower rocker arm 4 and a right lower rocker arm 5, the inner ends of the left upper rocker arm 2 and the right upper rocker arm 3 are hinged to the upper part of the main beam frame 1 through a pivot shaft 6, the left lower rocker arm 4 is hinged to the upper part of the main beam frame 1, and the left lower rocker arm 4 is hinged to the upper part of the main beam frame 1 through a pivot shaft 6. The inner ends of the rocker arm 4 and the right lower rocker arm 5 are hinged to the lower part of the main beam frame 1 through a pivot shaft 6, and a shock absorbing mechanism 7 is provided between the left upper rocker arm 2 and the right upper rocker arm 3 / between the left lower rocker arm 4 and the right lower rocker arm 5; the outer ends of the left upper rocker arm 2 and the left lower rocker arm 4 are respectively hinged to the left steering knuckle 27, and the outer ends of the right upper rocker arm 3 and the right lower rocker arm 5 are respectively hinged to the right steering knuckle 28. The left steering knuckle 27 is provided with a left front wheel 29, and the right steering knuckle 28 is provided with a right front wheel 30.

[0029] The main beam frame 1 is provided with a grafting assembly 8, and the grafting assembly 8 includes a grafting plate 9 and a plurality of grafting columns 10. The plurality of grafting columns 10 are fixed on the main beam frame 1. The two can be fixed together by bolts, or the two can be formed as one piece. One side of the grafting plate 9 is fixed to the connecting end of the plurality of grafting columns 10, and the other side connected to the grafting columns 10 can be fixed to the main frame 12 (this main frame is the main frame of a traditional two-wheeled vehicle). Through the grafting assembly 8, the yaw structure is connected to the main frame 12 of the traditional two-wheeled vehicle.

[0030] The structure of the grafting column 10 includes a base 13 and a connector 14 arranged at the outer end of the base 13. The connector 14 has a mounting hole 15. The grafting plate 9 is matched with the connector 14, and a through hole 16 is provided at the position corresponding to the mounting hole 15 on the grafting plate 9. A bolt 17 passes through the through hole 16 and the mounting hole 15, and a nut 18 is screwed on the other end of the bolt 17, thereby fixing the grafting plate 9 and the grafting column 10 together.

[0031] In order to improve the connection strength between the grafting column 10 and the grafting plate 9, we design the lengths of several grafting columns 10 to be inconsistent, so that the end-to-end connection lines between the ends of the grafting columns 10 connected to the grafting plate 9 form a regular / irregular shape. Specifically, the grafting column 10 has three, namely the upper grafting column 31, the middle grafting column 32, and the lower grafting column 33, and they are fixed on the main beam frame 1 at the top, middle, and bottom. The length of the middle grafting column 32 is greater than the length of the upper grafting column 31 and the lower grafting column 33, so that the end-to-end connection lines between the connection ends of the upper grafting column 31, the middle grafting column 32, and the lower grafting column 33 form a triangle. Of course, the lengths of the upper grafting column 31 and the lower grafting column 33 can be the same or different.

[0032] The connection line of the connection end is three grafting columns 10 of a triangular structure, so that the connection between the grafting plate 9 and the grafting columns 10 is more firm and stable, not easy to deform, and has high safety.

[0033] The lower grafting column 33 is arranged on the yaw main beam 19 at the bottom of the main beam frame 1, and the grafting plate 9 connects the upper grafting column 31, the middle grafting column 32, and the lower grafting column 33, thereby making the connection between the yaw main beam 19 and the main beam frame 1 more secure.

[0034] The grafting plate 9 includes a left connecting plate 20, a right connecting plate 21 and a support plate 22 connected to the upper half of the left connecting plate 20 and the right connecting plate 21. A spacing space 23 is formed between the left connecting plate 20 and the right connecting plate 21, and a plurality of connecting pins 24 are provided between the left connecting plate 20 and the right connecting plate 21; the main frame 12 matches the lower half of the spacing space 23 formed between the left connecting plate 20 and the right connecting plate 21.

[0035] Connecting pins 24 are positioned on the left and right connecting plates 20 and 21 between two adjacent grafting posts 10, at the corners between the support plate 22 and the left and right connecting plates 20 and 21, and in the lower half of the space 23 between the left and right connecting plates 20 and 21. This arrangement further enhances the connection strength between the grafting plate 9 and the grafting post 10.

[0036] The left connecting plate 20 and the right connecting plate 21 are symmetrically arranged on both sides, and the ends of the left connecting plate 20 and the right connecting plate 21 that are connected to the grafting column 10 are regular / irregular in shape.

[0037] In general, the grafting plate formed by the combination of the left connecting plate 20, the right connecting plate 21, and the support plate 22 has a low manufacturing cost, and its overall strength is improved by a number of connecting pins 24, which meets the manufacturing requirements of existing vehicles and meets the safety requirements; the left connecting plate 20 and the right connecting plate 21 with the spacing space 23 can accommodate the main frame 12, so that the welding area between the main frame 12 and the left connecting plate 20 and the right connecting plate 21 becomes larger and the connection is more secure; the front ends of the left connecting plate 20 and the right connecting plate 21 with regular / irregular shapes can not only reduce material consumption and reduce costs, but also avoid the related structures of the main beam frame 1.

[0038] In order to provide a welding space between the free end of the main frame 12 and the lower end surface of the support plate 22 and improve the connection strength, a neck groove 25 is provided on the left connecting plate 20 and the right connecting plate 21 at a position matching the lower end surface of the support plate 22, and the free end of the main frame 12 is located in the neck groove 25 position.

[0039] The following is an explanation of the installation process of the universal grafting structure for reverse tricycles of the present invention:

[0040] The first step is to remove the front wheel assembly of a regular two-wheeled vehicle;

[0041] In the second step, the grafting plate 9 is welded to the front end of the main frame 12 of the ordinary two-wheeled vehicle. At this time, the free end 26 of the main frame 12 is against the lower end of the support plate 22 of the grafting plate 9. By welding between the main frame 12 and the left connecting plate 20, the right connecting plate 21, the neck groove 25, and the lower end of the support plate 22, the grafting plate 9 is fixed to the main frame 12.

[0042] The third step is to match the front part of the grafting plate 9 with the through hole 16 with the grafting column 10, that is: several grafting columns 10 are inserted into the interval space 23 of the grafting plate 9, and the mounting holes 15 on the grafting columns 10 are aligned with the corresponding through holes 16. Finally, the bolts 17 are passed through the through holes 16 and the mounting holes 15, and the threaded section of the bolts 17 is extended to the outside of the grafting plate 9, and the nuts 18 are screwed on to complete the connection between the grafting plate 9 and the grafting columns 10.

[0043] The modified vehicle is transformed from a traditional two-wheeled vehicle into a reverse three-wheeled vehicle, including the main frame (on a traditional two-wheeled vehicle) and the yaw structure.

[0044] To sum up, the grafting structure of the present invention connects the main frame 12 of the traditional two-wheeled vehicle with the yaw structure through the grafting plate 9 and a number of grafting columns 10. It is only necessary to remove the front wheel assembly of the traditional two-wheeled vehicle as a whole and fix the other side of the grafting plate to the main frame 12 by welding / bolts (generally welding) or other fixing methods, thereby converting the traditional two-wheeled vehicle into a reverse three-wheeled vehicle.
