Description

Technical Field

[0001] The present application relates to the field of vehicle frames, and in particular to a high-strength shock-absorbing vehicle frame and a manufacturing method thereof. Background Art

[0002] The frame, as the backbone of the entire bicycle, greatly determines and influences the correctness and comfort of riding posture. Frame components are the basic structural element of a bicycle, serving as its backbone and main body. All other components are directly or indirectly mounted to the frame. Frame materials have evolved from chromium-molybdenum steel to aluminum alloys, and then to composite materials such as carbon fiber. Other materials include scandium alloys, magnesium alloys, and titanium alloys. The industry continues to develop new material formulations, enhance pipe and structural design capabilities, and innovate processing technologies, all in the name of making frames lighter, stronger, more comfortable, and more streamlined and aesthetically pleasing.

[0003] Mountain bikes are generally equipped with shock absorbers. In order to facilitate shock absorption and the installation of shock absorbers, the bicycle frame is divided into a front frame and a rear frame. The bottoms of the front frame and the rear frame are hinged to each other, and the tops of the front frame and the rear frame are connected by shock absorbers. When the mountain bike encounters uneven road sections, relative movement can be generated between the front frame and the rear frame, and shock absorption and buffering are performed through the shock absorbers.

[0004] With respect to the above-mentioned related technologies, the inventors believe that since the rider's weight is largely placed on the shock absorber, the strength of the connection between the shock absorber and the frame is particularly important, especially the connection between the shock absorber and the front frame. This causes a large load to be placed on the connection between the front frame and the shock absorber, making the connection between the front frame and the shock absorber prone to deformation. Summary of the Invention

[0005] In order to improve the strength of the connection between the shock absorber and the front frame, the present application provides a high-strength shock-absorbing frame and a manufacturing method thereof.

[0006] In a first aspect, the present application provides a high-strength shock-absorbing frame, which adopts the following technical solutions:

[0007] A high-strength shock-absorbing frame comprises a front frame and a rear frame hinged to each other at the bottom, wherein the middle portion of the front frame and the top portion of the rear frame are hinged via a shock absorber, wherein the front frame comprises a down tube, an arched connecting frame arranged at the top portion of the down tube, a seat tube arranged at the top portion of the arched connecting frame, and a head tube arranged at the top portion of the down tube, wherein the rear frame comprises a middle connecting frame hinged to the down tube, and an upper fork and a lower fork respectively arranged at the upper and lower ends of the middle connecting frame, wherein the shock absorber is hinged between the middle connecting frame and the arched connecting frame, wherein the arched connecting frame is hinged to the down tube. The frame includes an arc-shaped frame and flat plates arranged at both ends of the arc-shaped frame. The upper end of the shock absorber is provided with an upper hinge part hinged to the two flat plates. The inner side of the flat plate near the upper hinge part is provided with a reinforcing rib extending to the arc-shaped frame. Several groups of arched reinforcing ribs are provided between the two reinforcing ribs. The two adjacent groups of arched reinforcing ribs are connected by two cross-arranged oblique ribs. A support rod is provided on the side of the arched reinforcing rib close to the upper hinge part, and the end of the support rod is provided with a arc-shaped plate cooperating with the upper hinge part.

[0008] By adopting the above technical solution, when the shock absorber is operating, the front and rear frames rotate relative to each other, providing space for shock absorption and buffering. The reinforcing ribs enhance the strength of the flat panel and connect the flat panel to the curved frame, improving the connection strength between the flat panel and the curved frame, allowing the load to be transferred to the curved frame through the reinforcing ribs. The force applied by the shock absorber to the flat panel is partially transferred to the reinforcing ribs at both ends via the arched reinforcing ribs. Furthermore, the load of the arched reinforcing ribs can be transferred to another set of arched reinforcing ribs via two intersecting diagonal ribs, further enhancing the strength of the arched connecting frame.

[0009] Optionally, the arched reinforcement rib includes a plurality of arched strips arranged between two planar plates and a sealing strip connecting the openings of the plurality of arched strips, both ends of the sealing strip are connected to the reinforcement rib, and the oblique rib is arranged between two adjacent sealing strips.

[0010] By adopting the above technical solution, part of the force applied by the shock absorber to the flat plate can be transmitted to the sealing strip through the curved plate and the support rod. The sealing strip can not only transmit part of the load to the reinforcing ribs at both ends, but also to several arched strips above, thereby dispersing the load through the arched structure of the arched strip.

[0011] Optionally, a plurality of inverted arch frames are provided at both ends of the arc frame, a shock-absorbing plate is provided between the inverted arch frame and the arch bar, and both ends of the shock-absorbing plate are connected to the reinforcing ribs.

[0012] By adopting the above technical solution, the inverted arch frame can improve the connection stability between the curved frame and the flat panel, so that the load can be evenly distributed on each inverted arch frame, and the shock-absorbing plate can buffer and reduce the shock of the inverted arch frame and the arch bar.

[0013] Optionally, an airbag is provided in the gap between the inverted arch frame and the shock-absorbing plate, and an airbag is provided in the gap between the arch bar and the shock-absorbing plate.

[0014] By adopting the above technical solution, the gap between the inverted arch frame and the shock-absorbing plate can be filled, and the inverted arch frame and the arch bar can be further buffered and shock-absorbing.

[0015] Optionally, the upper hinge includes a connecting column arranged at the upper end of the shock absorber, an internal threaded barrel arranged at both ends of the connecting column, and a screw threadedly connected to the internal threaded barrel, the flat plate is located between the screw and the connecting column, and the arc plate cooperates with the connecting column.

[0016] By adopting the above technical solution, when the shock absorber is working, the internal threaded cylinder can generate relative rotation with the flat plate, thereby providing space for shock absorption and buffering.

[0017] Optionally, reinforcement flanges are provided at positions corresponding to the connecting columns on both inner and outer sides of the flat plate, the heads of the screws contact the inner walls of the reinforcement flanges, and the outer sides of the connecting columns contact the inner walls of the reinforcement flanges.

[0018] By adopting the above technical solution, the load of the connecting column can be transferred to the flat plate through the reinforced flange, thereby further improving the strength of the flat plate.

[0019] Optionally, a plurality of notches are formed at the end of the reinforcement flange, and rubber connecting blocks are provided in the notches.

[0020] By adopting the above technical solution, when the load borne by the reinforcement flange is too large, the reinforcement flange can produce a certain deformation, thereby reducing the phenomenon of the reinforcement flange being damaged due to rigidity.

[0021] Optionally, the end of the planar plate close to the shock absorber is arc-shaped, and the end of the planar plate close to the shock absorber is provided with an arc-shaped rib.

[0022] By adopting the above technical solution, the load can be distributed to the upper tube and the lower tube more smoothly. The provision of the arc-shaped ribs can reinforce the ends of the flat plate and improve the overall strength of the flat plate.

[0023] Optionally, both ends of the reinforcing rib are provided with a plane rib connected to the plane plate, and one end of the plane rib away from the reinforcing rib is connected to the arc rib.

[0024] By adopting the above technical solution, the plane ribs can transfer the load borne by the reinforcing ribs to the arc-shaped ribs, thereby improving the overall strength of the plane plate.

[0025] In a second aspect, the present application provides a method for manufacturing a high-strength shock-absorbing frame, which adopts the following technical solution and includes the following steps:

[0026] S1: Using the lower tube as a reference, calibrate the opening of the two plane plates;

[0027] S2: Taking the lower tube as the reference, check the opening degree of the two flat plates;

[0028] S3: Using the center connecting frame as a reference, adjust the upper forks and lower forks at different positions of the rear frame so that the midpoint between the two upper forks and the midpoint between the two lower forks are at the centerline of the rear frame;

[0029] S4: Based on the middle connecting frame, check the opening degree of the upper fork and the lower fork;

[0030] S5: Check the inner diameter of the head tube and the inner diameter of the seat tube;

[0031] S6: Flatness inspection of the lower fork disc brake surface.

[0032] By adopting the above technical solution, the front frame and the rear frame are separately inspected and calibrated to improve the consistency after assembly. Because the front frame and the rear frame are die-cast separately, it can be ensured that the center line of the front frame and the center line of the rear frame are in a straight line. The spacing between the upper forks and the lower forks is inspected and the opening degree is corrected, so that subsequent assembly does not need to be one-to-one.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. Part of the force exerted by the shock absorber on the flat plate can be transferred to the reinforcement ribs at both ends through the arched reinforcement ribs. In addition, the load of the arched reinforcement ribs can be transferred to another set of arched reinforcement ribs through two cross-arranged oblique ribs, thereby further improving the strength of the arched connecting frame.

[0035] 2. The inverted arch frame can improve the connection stability between the curved frame and the flat panel, so that the load can be evenly distributed on each inverted arch frame. The shock-absorbing plate can buffer and reduce the shock of the inverted arch frame and the arch strip;

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-4 This application is described in further detail.

[0043] The embodiment of the present application discloses a high-strength shock-absorbing frame. Figure 1 The high-strength shock-absorbing frame includes a front frame and a rear frame. The bottom end of the front frame is hinged to the front bottom end of the rear frame. A shock absorber 1 is installed between the front frame and the rear frame. The two ends of the shock absorber 1 are respectively hinged to the middle of the front frame and the top of the rear frame.

[0044] The front frame includes a down tube 2, an arched connecting frame 3, a seat tube 4, and a head tube 5. The arched connecting frame 3 is integrally formed at the top of the middle portion of the down tube 2. The seat tube 4 is integrally formed at the top of the arched connecting frame 3. A top tube 6 is integrally formed at the front end of the seat tube 4. The head tube 5 is integrally formed at the front ends of the down tube 2 and top tube 6. In this embodiment, the front frame is made of magnesium alloy.

[0045] The rear frame includes a center link 7, an upper fork 8, and a lower fork 9. The bottom end of the center link 7 is hinged to the bottom end of the down tube 2. The shock absorber 1 is hinged between the top of the center link 7 and the middle of the arched connecting frame 3. The upper fork 8 is integrally formed at the rear end of the top of the center link 7. Two upper forks 8 are provided, and the two upper forks 8 are arranged on the left and right. The lower forks 9 are integrally formed at the rear end of the bottom end of the center link 7. Two lower forks 9 are also arranged on the left and right. The upper forks 8 and lower forks 9 on the same side are connected to each other at a position away from the center link 7, forming a disc brake frame 10. It should be noted that the side of the two disc brake frames 10 that are close to each other is the disc brake surface. In this embodiment, the rear frame is made of magnesium alloy.

[0046] Reference Figure 2The arched connecting frame 3 includes an integrally formed arc frame 11 and a flat panel 12. The arc frame 11 and the flat panel 12 are integrally formed between the upper tube 6 and the lower tube 2. A triangle is formed between the arc frame 11, the upper tube 6, and the lower tube 2, which can increase the overall stability of the front frame. The cross-section of the arc frame 11 is C-shaped, and two flat panels 12 are provided. The two flat panels 12 are respectively located at the two end positions of the arc frame 11. It should be noted that an upper hinge is installed at the upper end of the shock absorber 1, and the upper hinge is hinged to the two flat panels 12. When the bicycle encounters an uneven road section, relative movement can occur between the front frame and the rear frame, and shock absorption and buffering are provided by the shock absorber 1.

[0047] Reference Figure 3 In this embodiment, the upper hinge includes a connecting post 13, an internally threaded barrel 14, and a screw 15. The connecting post 13 is fixed to the upper end of the shock absorber 1 and positioned between the two flat plates 12. The internally threaded barrel 14 is fixedly connected to opposite ends of the connecting post 13. The outer diameter of the internally threaded barrel 14 is smaller than that of the connecting post 13. The flat plates 12 have through-holes for the internally threaded barrel 14 to pass through. The internally threaded barrel 14 passes through and extends outside the flat plates 12, allowing relative movement between the internally threaded barrel 14 and the flat plates 12. The screw 15 is threadedly connected to the internally threaded barrel 14, and the flat plates 12 are positioned between the screw 15 and the connecting post 13. When the shock absorber 1 is operating, the internally threaded barrel 14 can rotate relative to the flat plates 12, thereby providing space for shock absorption and buffering.

[0048] To improve the overall stability of the flat plate 12, the end of the flat plate 12 near the shock absorber 1 is configured to be curved, and a curved rib 16 is integrally formed at the end of the flat plate 12 near the shock absorber 1. The thickness of the curved rib 16 is slightly greater than the thickness of the flat plate 12. The curved end of the flat plate 12 can smoothly distribute the load to the upper tube 6 and the down tube 2. The provision of the curved rib 16 can also reinforce the end of the flat plate 12 and improve the overall strength of the flat plate 12.

[0049] Furthermore, both ends of the reinforcing rib 18 are integrally formed with a planar rib 17, and the ends of the two planar ribs 17 away from the reinforcing rib 18 are respectively fixed to the upper and lower ends of the arc-shaped rib 16. In addition, the planar rib 17 and the flat panel 12 are integrally formed, and the planar rib 17 can transfer the load borne by the reinforcing rib 18 to the arc-shaped rib 16, thereby improving the overall strength of the flat panel 12.

[0050] Reference Figure 3 and Figure 4Preferably, to improve the overall stability of the planar panels 12, reinforcing ribs 18 are integrally formed on the adjacent sides of the two planar panels 12. The ends of the reinforcing ribs 18 extend to the arcuate frame 11 and a position near the connecting column 13, respectively. Two sets of arched reinforcing ribs 19 are installed between the two reinforcing ribs 18. The arched reinforcing ribs 19 include arched strips 20 and sealing strips 21. Several arched strips 20 are provided, and the ends of two adjacent arched strips 20 are connected to each other. The sealing strips 21 are fixed between the two reinforcing ribs 18 and are fixed to the ends of the arched strips 20, so that the sealing strips 21 can connect the openings of the arched strips 20. The thickness of the sealing strip 21 is greater than that of the arched strips 20. Two oblique ribs 22 are fixed between two adjacent sealing strips 21. The two oblique ribs 22 are arranged in a cross pattern, and both ends of the oblique ribs 22 are connected to the reinforcing ribs 18.

[0051] Two support rods 23 are fixed to the end of the sealing strip 21 closer to the upper hinge away from the arch strip 20 . An arc plate 24 is fixed to the end of the support rod 23 away from the sealing strip 21 , and the arc plate 24 cooperates with the outer side of the connecting column 13 .

[0052] The reinforcing ribs 18 not only enhance the strength of the flat panel 12 but also connect the flat panel 12 to the curved frame 11, improving the connection strength between the two, allowing the load to be transferred to the curved frame 11 via the reinforcing ribs 18. Furthermore, a portion of the force applied by the connecting column 13 to the flat panel 12 is transferred to the sealing strip 21 via the curved plate 24 and support rod 23. The sealing strip 21 transfers a portion of the load not only to the reinforcing ribs 18 at both ends but also to the several arched strips 20 above, distributing the load through the arched structure of the arched strips 20. Furthermore, the load of the sealing strip 21 is transferred to another set of arched reinforcing ribs 19 via two intersecting oblique ribs 22, further enhancing the strength of the arched connecting frame 3.

[0053] Preferably, a plurality of inverted arched frames 25 are fixed at both ends of the arcuate frame 11. The openings of the inverted arched frames 25 face away from the openings of the arched bars 20. The number of inverted arched frames 25 is equal to the number of arched bars 20 in a set of arched reinforcing ribs 19. A space is reserved between the inverted arched frames 25 and the arched bars 20, within which a shock-absorbing plate 26 is fixed. Both ends of the shock-absorbing plate 26 are secured to the reinforcing ribs 18. In this embodiment, the shock-absorbing plate 26 is made of rubber and has certain shock-absorbing properties. In addition, an airbag 27 is fixed in the gap between the inverted arched frames 25 and the shock-absorbing plate 26, and an airbag 27 is also fixed in the gap between the arched bars 20 and the shock-absorbing plate 26. It should be noted that the plurality of inverted arch frames 25 improve the connection stability between the curved frame 11 and the flat panel 12, allowing the load to be evenly distributed across each inverted arch frame 25. The shock-absorbing plates 26 provide cushioning and vibration reduction for the inverted arch frames 25 and the arch bars 20, while also allowing for slight movement between the inverted arch frames 25 and the arch bars 20. The airbags 27, filled with gas, can fill the gaps between the inverted arch frames 25 and the shock-absorbing plates 26, as well as the gaps between the arch bars 20 and the shock-absorbing plates 26, further cushioning and reducing vibration for the inverted arch frames 25 and the arch bars 20.

[0054] Furthermore, reinforcing flanges 28 are integrally formed on both the inner and outer sides of the planar panel 12 at locations corresponding to the connecting posts 13. The inner sides of the reinforcing flanges 28 mate with the heads of the screws 15, while the outer sides of the connecting posts 13 mate with the inner walls of the reinforcing flanges 28. The provision of the reinforcing flanges 28 serves to limit the position of the connecting posts 13 and the screws 15, reducing their misalignment. Furthermore, the load of the connecting posts 13 is transferred to the planar panel 12 via the reinforcing flanges 28, further enhancing the strength of the planar panel 12.

[0055] Preferably, the end of the reinforcing flange 28 away from the flat plate 12 is provided with a plurality of notches 29. The notches 29 extend through both the inner and outer sides of the reinforcing flange 28. Rubber connectors 30 are glued into the notches 29. Furthermore, the outer sides of the rubber connectors 30 are concavely curved. In this embodiment, the rubber connectors 30 are made of a rubber material and have a certain degree of elasticity.

[0056] It should be noted that the setting of the notch 29 enables the reinforcement flange 28 to have the ability to produce deformation. When the load borne by the reinforcement flange 28 is too large, the reinforcement flange 28 can produce a certain deformation, reducing the phenomenon of the reinforcement flange 28 being damaged due to rigidity. The setting of the rubber connecting block 30 can elastically connect the notch 29, further improving the strength of the reinforcement flange 28.

[0057] The present application also discloses a method for manufacturing a high-strength shock-absorbing frame, which comprises the following steps:

[0058] S1: Using the lower tube 2 as a reference, calibrate the opening of the two flat panels 12;

[0059] S2: Taking the lower tube 2 as a reference, the opening degree of the two flat plates 12 is inspected;

[0060] S3: Using the middle connecting frame 7 as a reference, aligning the upper forks 8 and lower forks 9 at different positions of the rear frame so that the midpoint between the two upper forks 8 and the midpoint between the two lower forks 9 are located at the centerline of the rear frame;

[0061] S4: Taking the middle connecting frame 7 as a reference, the opening degree of the upper fork 8 and the lower fork 9 is inspected;

[0062] S5: Inspect the inner diameter of the head tube 5 and the inner diameter of the seat tube 4;

[0063] S6: Flatness inspection of the lower fork 9 disc brake surface.

[0064] The implementation principle of the manufacturing method of a high-strength shock-absorbing frame in the embodiment of the present application is as follows: the front frame and the rear frame are separately inspected and calibrated to improve the consistency after assembly. Because the front frame and the rear frame are separately die-cast, this ensures that the center line of the front frame and the center line of the rear frame are in a straight line. The spacing between the upper forks 8 and the lower forks 9 is inspected and the opening degree is corrected. Subsequent assembly does not need to be one-to-one, and can be distributed separately to the partners, who can directly assemble them. It should be noted that if the front frame and the rear frame are assembled and calibrated as a whole in the factory, when the rear frame is replaced, the rear frame may not match the front frame (not in a straight line). If these two processes of calibration and inspection are not performed, the entire frame must be assembled and calibrated in the factory, and then the front frame and the rear frame must be labeled separately before being sent to the partners. The partners then disassemble the front frame and the rear frame and spray-paint them separately, which makes the process cumbersome.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
