Description

Technical Field

[0001] This utility model relates to the field of two-wheeled vehicle technology, and in particular to a two-wheeled vehicle frame and a two-wheeled vehicle. Background Technology

[0002] Two-wheeled vehicles, such as electric bicycles, scooter bikes, or fuel-powered vehicles, typically have a rear swingarm mounting plate welded to the side tube of the frame. The rear swingarm is then fastened to the frame using the mounting plate and bolt assemblies, thus assembling the frame and the rear swingarm.

[0003] However, the torsional stiffness of the rear swingarm mounting plate in the relevant technology is insufficient, and the frame is easily twisted by the rear swingarm, which is not conducive to the normal use of the two-wheeled vehicle. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one embodiment of this utility model proposes a frame for a two-wheeled vehicle, which improves the overall strength and torsional stiffness of the frame and has a simple overall structure.

[0006] Another embodiment of this utility model proposes a two-wheeled vehicle.

[0007] A two-wheeled vehicle frame according to an embodiment of the present invention includes an upper tube, a tail tube, and a mounting bracket. The rear end of the upper tube is connected to the tail tube to form a connection. The mounting bracket is disposed on the side of the tail tube away from the upper tube, and at least a portion of the mounting bracket extends along the extension direction of the tail tube to above the connection.

[0008] According to an embodiment of the present invention, the frame of a two-wheeled vehicle consists of a top tube, a tail tube, and a mounting bracket, which together form a rear swingarm mounting structure on the frame. Since at least a portion of the mounting bracket extends along the extension direction of the tail tube to above the connection point, that is, the extension length of the mounting bracket exceeds the connection area between the top tube and the tail tube, the strength of the connection point can be reinforced, thereby increasing the overall strength of the rear swingarm mounting structure. After the rear swingarm is connected to the mounting bracket, the overall torsional stiffness of the frame is improved. Therefore, compared with related technologies, the present invention improves the overall strength and torsional stiffness of the frame, and the overall structure is simple.

[0009] In some embodiments, the mounting bracket includes a mounting body and an extension, the mounting body being located below the connection, and the extension extending upward from the top of the mounting body along the extension direction of the tail tube and extending above the connection.

[0010] In some embodiments, the mounting bracket includes an outer mounting plate and an inner mounting plate connected together, the outer mounting plate and the inner mounting plate being arranged along the thickness direction of the outer mounting plate, the thickness direction of the outer mounting plate being orthogonal to the vertical direction, and the side of the inner mounting plate opposite to the outer mounting plate being adapted to be connected to the rear horizontal fork of the two-wheeled vehicle.

[0011] In some embodiments, each of the outer mounting plate and the inner mounting plate is connected to the tailpipe on the side opposite to the rear swingarm, and at least a portion of the outer mounting plate and the inner mounting plate extends above the connection point.

[0012] In some embodiments, the inner mounting plate has a cavity on its side facing the outer mounting plate, and the outer mounting plate covers one end of the cavity facing the outer mounting plate.

[0013] In some embodiments, the inner mounting plate is further provided with a countersunk groove on the side facing the outer mounting plate, and the side of the inner mounting plate away from the outer mounting plate includes a mating surface opposite to the bottom surface of the countersunk groove, the mating surface being connected to the rear horizontal fork.

[0014] In some embodiments, the outer mounting plate has mounting holes opposite to the countersunk groove, the mounting holes penetrating the outer mounting plate along its thickness direction, and the edge of the mounting hole away from the countersunk groove has a chamfer.

[0015] In some embodiments, the frame further includes a head tube, a riser tube, and a support tube. The head tube is connected to the riser tube, and the portion of the riser tube facing away from the head tube is connected to the upper tube. The support tube is located on the side of the head tube facing away from the riser tube, and the end of the support tube facing away from the head tube is provided with a connecting plate. The side of the connecting plate facing away from the support tube is adapted to be connected to the front panel of the two-wheeled vehicle.

[0016] In some embodiments, the outer contour of the cross-section of the support tube is one of a circle, a square, and any closed curve.

[0017] In some embodiments, the cross-sectional area of ​​the support tube is smaller than the cross-sectional area of ​​the head tube.

[0018] In some embodiments, the frame further includes a support frame and a steering lock zipper. The support frame is disposed at the end of the tail tube opposite to the upper tube. The support frame includes a mounting portion and a tail portion connected to each other in a front-rear direction. The support frame has a through notch in a vertical direction, which extends from back to front and at least partially extends to the mounting portion. The steering lock zipper engages with the notch and abuts against the top surface of the mounting portion. The tail portion is used to limit the steering lock zipper in the extending direction of the notch.

[0019] In some embodiments, the top surface of the tail extends in an upward direction and slopes backward.

[0020] In some embodiments, on the projection planes formed in the vertical and horizontal directions, the top projection of the tail portion and the top projection of the mounting portion form an angle α, where α is 20°-30°.

[0021] A two-wheeled vehicle according to an embodiment of the present invention includes a rear swingarm and a frame, wherein the frame is the frame described in any of the above embodiments, and the mounting bracket of the frame is connected to the rear swingarm.

[0022] According to the embodiments of the present invention, the mounting bracket in the frame for connecting with the rear swingarm is designed to extend beyond the connection area of ​​the top tube and the tail tube, so that the overall strength of the rear swingarm mounting structure in the frame is high and the torsional stiffness can be improved. Therefore, compared with related technologies, the two-wheeled vehicle using this frame can ensure performance and reliability.

[0042] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] like Figure 1 and Figure 2 As shown, a two-wheeled vehicle frame 100 according to an embodiment of the present invention includes an upper tube 1, a tail tube 2, and a mounting bracket 3. The rear end of the upper tube 1 is connected to the tail tube 2 to form a connection 21. The mounting bracket 3 is located on the side of the tail tube 2 away from the upper tube 1, and at least a portion of the mounting bracket 3 extends along the extending direction of the tail tube 2 to above the connection 21. The mounting bracket 3 is adapted to be connected to the rear swingarm 200 of the two-wheeled vehicle.

[0044] According to an embodiment of the present invention, the frame 100 of a two-wheeled vehicle consists of an upper tube 1, a tail tube 2, and a mounting bracket 3, which together form a rear swingarm 200 mounting structure on the frame 100. Since at least a portion of the mounting bracket 3 extends along the extension direction of the tail tube 2 to above the connection 21, that is, the extension length of the mounting bracket 3 exceeds the connection area between the upper tube 1 and the tail tube 2, it can strengthen the connection 21, thereby increasing the overall strength of the rear swingarm 200 mounting structure. After the rear swingarm 200 is connected to the mounting bracket 3, the overall torsional stiffness of the frame 100 is improved. Therefore, compared with related technologies, the present invention improves the overall strength and torsional stiffness of the frame 100, and the overall structure is simple.

[0045] Specifically, the rear end of the upper tube 1 can be welded to the tail tube 2, and the mounting bracket 3 can be welded to the tail tube 2. This allows the portion of the mounting bracket 3 extending above the connection 21 to effectively reinforce the strength of the weld between the upper tube 1 and the tail tube 2, thereby enhancing the strength of the rear horizontal fork 200 mounting structure. The tail tube 2 can extend from bottom to top and be arranged at a rearward inclination. The mounting bracket 3 can be formed with a connecting ear 31, which can contact and connect with the outer peripheral surface of the tail tube 2. In other words, the connecting ear 31 covers the outer peripheral surface of the tail tube 2 and can be welded to the outer peripheral surface of the tail tube 2, further ensuring the reliability of the connection between the mounting bracket 3 and the tail tube 2 and increasing the structural strength between them.

[0046] Additionally, the frame 100 may include a lower side tube 4, which is spaced apart from the upper side tube 1 in the vertical direction, and the rear end of the lower side tube 4 is connected to the tail tube 2. For example, the lower side tube 4 may be integrally formed with the tail tube 2. The first end (i.e., the top end) of the mounting bracket 3 extends above the connection 21, and the second end (i.e., the bottom end) of the mounting bracket 3 may extend to the front side of the area where the lower side tube 4 and the tail tube 2 are connected, so as to further increase the overall strength of the rear swingarm 200 mounting structure and improve the torsional stiffness of the frame 100.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting bracket 3 includes a mounting body 321 and an extension 322. The mounting body 321 is located below the connection 21, and the extension 322 extends upward from the top of the mounting body 321 along the extension direction of the tail tube 2 and extends above the connection 21. The design of the extension 322 can strengthen the strength of the connection 21, increase the overall length of the mounting bracket 3, and the connection between the extension 322 and the tail tube 2 also increases the connection area to a certain extent, thus enhancing the overall strength of the rear swingarm 200 mounting structure.

[0048] Specifically, in conjunction with the above structure, the end of the extension 322 away from the mounting body 321 can extend to the top of the connection 21, and the end of the mounting body 321 away from the extension 322 can extend to the front side of the area where the lower tube 4 and the tail tube 2 are connected.

[0049] like Figure 2 As shown, in some embodiments, the mounting bracket 3 includes an outer mounting plate 32 and an inner mounting plate 33 connected together. The outer mounting plate 32 and the inner mounting plate 33 are arranged along the thickness direction of the outer mounting plate 32, which is orthogonal to the vertical direction. The side of the inner mounting plate 33 facing away from the outer mounting plate 32 is adapted to be connected to the rear horizontal fork 200 of the two-wheeled vehicle.

[0050] Understandably, the double-layer structure formed by the outer mounting plate 32 and the inner mounting plate 33 can further increase the overall structural strength of the mounting bracket 3, which is beneficial to improving the overall torsional stiffness of the frame 100.

[0051] Specifically, the outer mounting plate 32 and the inner mounting plate 33 can be welded together to further enhance the overall structural strength of the mounting bracket 3. Both the outer mounting plate 32 and the inner mounting plate 33 can be sheet metal parts.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, each of the outer mounting plate 32 and the inner mounting plate 33 is connected to the tailpipe 2 on the side opposite to the rear swingarm 200, and at least a portion of the outer mounting plate 32 and the inner mounting plate 33 extends above the connection 21.

[0053] It is understandable that since both the outer mounting plate 32 and the inner mounting plate 33 are connected to the tailpipe 2, the overall connection area between the mounting bracket 3 and the tailpipe 2 is increased. Furthermore, at least a portion of the outer mounting plate 32 and the inner mounting plate 33 extends above the connection point 21, which can strengthen the connection point 21 and increase the overall length of the outer mounting plate 32 or the inner mounting plate 33 to increase the connection area with the tailpipe 2. Therefore, the aforementioned structural design can effectively improve the overall strength and torsional stiffness of the frame 100.

[0054] Specifically, at least a portion of the outer mounting plate 32 extends above the connection 21, in other words, the outer mounting plate 32 has an extension 322; or, at least a portion of the inner mounting plate 33 extends above the connection 21, in other words, the inner mounting plate 33 has an extension 322; or, at least a portion of each of the outer mounting plate 32 and the inner mounting plate 33 extends above the connection 21, in which case each of the outer mounting plate 32 and the inner mounting plate 33 may include a mounting body 321 and an extension 322.

[0055] Furthermore, based on the above structure, it can be seen that each of the outer mounting plate 32 and the inner mounting plate 33 can have a connecting ear 31 formed on the side away from the rear horizontal fork 200. There can be multiple connecting ears 31, which are arranged at intervals along the extension direction of the outer mounting plate 32 or the extension direction of the inner mounting plate 33. The extension direction of the outer mounting plate 32 and the extension direction of the inner mounting plate 33 can be consistent with the extension direction of the tailpipe 2. The specific number and spacing of the connecting ears 31 can be designed according to the length of the outer mounting plate 32 or the length of the inner mounting plate 33 to ensure the reliability of the connection between each of the outer mounting plate 32 and the inner mounting plate 33 and the tailpipe 2. This will not be elaborated on in detail here.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the inner mounting plate 33 has a cavity on the side facing the outer mounting plate 32, and the outer mounting plate 32 covers one end of the cavity facing the outer mounting plate 32 to define a cavity between the two.

[0057] Understandably, the structural design that forms a cavity sandwich between the inner mounting plate 33 and the outer mounting plate 32 can further enhance the torsional stiffness of the frame 100 and reduce the impact of the rear swingarm 200's operation on the frame 100.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the inner mounting plate 33 is further provided with a countersunk groove 331 on the side facing the outer mounting plate 32, and the side of the inner mounting plate 33 away from the outer mounting plate 32 includes a mating surface 332 opposite to the bottom surface of the countersunk groove 331, and the mating surface 332 is connected to the rear horizontal fork 200.

[0059] Specifically, the countersunk groove 331 can protrude towards the rear horizontal fork 200, that is, a portion of the side of the inner mounting plate 33 facing away from the outer mounting plate 32 protrudes towards the rear horizontal fork 200, so as to facilitate the connection between the rear horizontal fork 200 and the countersunk groove 331 and improve the structural strength at the connection position between the inner mounting plate 33 and the rear horizontal fork 200. The mating surface 332 can be a plane so that the mating surface 332 contacts the surface of the rear horizontal fork 200, reducing the difficulty of mating and production, and making the overall structure simple and easy to assemble and disassemble.

[0060] like Figure 4 As shown, the frame 100 may also include a fastener 5. The inner mounting plate 33 has a through hole 333 extending through it along its thickness direction. One end of the fastener 5 passes through the through hole 333 and connects to the rear swingarm 200, thereby achieving a secure connection between the inner mounting plate 33 and the rear swingarm 200. The fastener 5 may be a bolt, screw, or stud, or other component capable of achieving a fastening function. The through hole 333 is located on the bottom surface of the countersunk groove 331, allowing the fastener 5 to be recessed for installation.

[0061] Understandably, the countersunk groove 331 can hide the fastener 5 used to secure the rear swingarm 200 in the mounting bracket 3, thereby reducing the corrosion of the fastener 5 by the external environment, ensuring its service life, and improving the aesthetics of the frame 100.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments, the outer mounting plate 32 is provided with a mounting hole 323 opposite to the countersunk groove 331. The mounting hole 323 penetrates the outer mounting plate 32 along the thickness direction of the outer mounting plate 32, and the edge of the mounting hole 323 away from the countersunk groove 331 has a chamfer 3231.

[0063] Understandably, the mounting holes 323 on the outer mounting plate 32 allow workers to manually pass the fasteners 5 through the through holes 333 and pre-tighten them in the rear swingarm 200 when assembling the rear swingarm 200 on the frame 100, thus achieving pre-assembly between the rear swingarm 200 and the mounting bracket 3. At the same time, because the edge of the mounting hole 323 has a chamfer 3231, the area at the end of the mounting hole 323 can be further increased to widen the operating space, which is beneficial for workers to manually tighten the fasteners 5 and can also effectively avoid the problem that the burrs on the edge of the mounting hole 323 can easily scratch the workers' hands.

[0064] Specifically, the chamfer 3231 can be either a rounded corner or a beveled corner, preferably a rounded corner, which means that the mounting hole 323 is recessed inward. The recess can enhance the strength of the sheet metal part, thus strengthening the strength of the outer mounting plate 32 itself.

[0065] like Figure 1 As shown, in some embodiments, the frame 100 further includes a head tube 6, a riser tube 7, and a support tube 8. The head tube 6 is connected to the riser tube 7, and the portion of the riser tube 7 facing away from the head tube 6 is connected to the upper tube 1 and the lower tube 4. The support tube 8 is located on the side of the head tube 6 facing away from the riser tube 7, and the end of the support tube 8 facing away from the head tube 6 is provided with a connecting plate 81. The side of the connecting plate 81 facing away from the support tube 8 is adapted to be connected to the front panel of the two-wheeled vehicle.

[0066] It is understandable that the cantilever structure for supporting the front panel is formed by the combination of the support tube 8 and the connecting plate 81. Compared with the sheet metal cantilever structure in related technologies, the cantilever of this utility model is stronger and can provide sufficient strength to support the front panel. It also makes the space between the front panel and the windshield (that is, the head space of the frame 100) larger, which can facilitate the routing of cables and oil pipes.

[0067] Specifically, the front tube 6 can be welded to the top of the riser tube 7. The riser tube 7 can be welded to the upper tube 1 and the lower tube 4. The support tube 8 can be located in front of the front tube 6. The support tube 8 can extend from bottom to top and be inclined towards the front panel, that is, the support tube 8 can be inclined upwards towards the front panel. The support tube 8 can be a welded tube, and the cantilever strength of the welded tube is higher than that of the sheet metal part. The support tube 8 can be welded to the connecting plate 81 to ensure the structural strength of the cantilever structure. The connecting plate 81 can be a sheet metal part. The connecting plate 81 can be perpendicularly connected to the support tube 8. The front panel of the two-wheeled vehicle is not limited to being fixed to the connecting plate 81 by screws or the like.

[0068] like Figure 1As shown, in some embodiments, the outer contour of the cross-section of the support tube 8 is one of a circle, a square, and an arbitrary closed curve. Preferably, the outer contour of the cross-section of the support tube 8 is a regular closed curve, such as a circle or a square, so that when the throttle lock 92 rotates during cable routing and oil pipe routing, the cable harness and oil pipe will slide against the smooth outer surface of the support tube 8, thereby protecting the oil pipe and cable harness in the head space of the frame 100 from wear.

[0069] like Figure 1 As shown, in some embodiments, the cross-sectional area of ​​the support tube 8 is smaller than that of the head tube 6, so as to further reduce the space occupied by the cantilever structure at the head of the frame 100 while ensuring the support strength of the cantilever structure.

[0070] like Figures 1 to 3 As shown, in some embodiments, the frame 100 further includes a support frame 91 and a steering wheel lock 92. The support frame 91 is located at the end of the tail tube 2 away from the upper tube 1. The support frame 91 includes a mounting portion 911 and a tail portion 912 connected to each other in the front-rear direction. The support frame 91 has a notch 913 that extends through in the vertical direction. The notch 913 extends from back to front and at least partially extends to the mounting portion 911. The steering wheel lock 92 is fitted into the notch 913 and abuts against the top surface of the mounting portion 911. The tail portion 912 is used to limit the steering wheel lock 92 in the extending direction of the notch 913.

[0071] It is understandable that during the pre-assembly of the vehicle, the steering lock 92 needs to be assembled onto the frame 100 first, and then other components are assembled. The steering lock 92 is relatively rigid and is prone to falling off when it slides into the notch 913. However, the tail 912 can constrain and limit the steering lock 92 to prevent it from slipping off, thus improving production efficiency.

[0072] Specifically, the support frame 91 can be installed on the top of the tail tube 2 and is located outside the tail tube 2. The tail portion 912 is located behind the mounting portion 911.

[0073] like Figure 3 As shown, in some embodiments, the top surface of the tail 912 extends from bottom to top and tilts backward; in other words, the top surface of the tail 912 is upturned, so as to effectively reduce the risk of the faucet lock 92 falling off when the faucet lock zipper 92 is pre-assembled onto the support frame 91.

[0074] Specifically, the tail section 912 can be tilted upward relative to the mounting section 911 to further simplify the structure of the support frame 91 and reduce production difficulty.

[0075] like Figure 3As shown, in some embodiments, on the projection plane formed in the vertical and horizontal directions, the top projection of the tail 912 and the top projection of the mounting part 911 form an angle α, and α is 20°-30°. For example, α can be 20°, 22°, 24°, 26°, 28°, 30°, etc., but is not limited to the listed values. Other unlisted values ​​within this range are also applicable.

[0076] Understandably, by adopting the above parameter design, the top surface of the tail 912 relative to the mounting part 911 can be raised to a certain extent, so as to form a constraint limit on the faucet lock 92 on the support frame 91.

[0077] It should be noted that the "projection plane" is a plane that is parallel to both the vertical and horizontal directions.

[0078] like Figure 4 and Figure 5 As shown, a two-wheeled vehicle 10 according to an embodiment of the present invention includes a rear horizontal fork 200 and a frame 100. The frame 100 is the frame 100 of any of the above embodiments. The mounting bracket 3 of the frame 100 is connected to the rear horizontal fork 200.

[0079] According to the embodiment of the present invention, the mounting bracket 3 in the frame 100 for connecting with the rear swingarm 200 is designed to extend beyond the connection area of ​​the upper tube 1 and the tail tube 2, so that the overall strength of the mounting structure of the rear swingarm 200 in the frame 100 is high and the torsional stiffness can be improved. Therefore, compared with related technologies, the two-wheeled vehicle 10 using this frame 100 can ensure performance and reliability.

[0080] Specifically, the mounting bracket 3 is pivotally connected to the rear swingarm 200 so that the rear swingarm 200 can move accordingly when the vehicle body is shock-absorbing and extending (that is, when the rear wheel is shock-absorbing relative to the frame 100). At this time, the rear swingarm 200 rotates relative to the mounting bracket 3. The mounting bracket 3 in this utility model, together with the upper tube 1 and the tail tube 2, forms the rear swingarm 200 mounting structure, which improves the overall strength. Therefore, it can reduce the impact of the rear swingarm 200's movement on the frame 100 and strengthen the torsional stiffness of the frame 100.

[0081] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
