[0026] 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.
[0027] The following is combined Figures 1-5 Description of a rear frame assembly according to an embodiment of the present invention.
[0028] The rear frame assembly of this utility model embodiment includes a rear frame 1, a rear swingarm 2, and rear footrests 3. The rear swingarm 2 is connected to the rear frame 1, and there are two rear footrests 3, both of which are connected to the rear swingarm 2. At least a portion of each of the two rear footrests 3 protrudes from opposite sides of the rear frame 1 in the left-right direction, and both rear footrests 3 are located below the rear frame 1.
[0029] According to the rear frame assembly of this utility model embodiment, by connecting the rear footrest 3 to the rear horizontal fork 2 and positioning the rear footrest 3 below the rear frame 1, the distance between the rear footrest 3 and the upper surface of the rear seat is longer, allowing passengers to stretch their legs better when sitting on the rear seat, thus improving the riding experience for rear passengers.
[0030] It should be noted that by connecting the rear footrest 3 to the rear swingarm 2 instead of the rear frame 1, the distance between the rear footrest 3 and the upper surface of the rear seat can be made longer without additional adjustments to the size of the rear frame 1, resulting in lower vehicle modification costs.
[0031] In some embodiments, the rear swingarm 2 includes two rear fork plates 21 located below the rear frame 1, the two rear fork plates 21 being spaced apart in the left-right direction. The rear footrests 3 are respectively connected to the opposite sides of the two rear fork plates 21.
[0032] At this time, the two rear fork plates 21 are opposite sides of each other and are planes at an angle to the left and right directions. Compared with the rear footrest 3 being connected to the round tube on the rear frame 1, the connection between the rear footrest 3 and the rear fork plate 21 is easier and the connection between the two is more reliable and stronger.
[0033] For example, such as Figure 1 and Figure 2As shown, the two rear fork plates 21 are arranged in a roughly mirror-symmetrical manner with respect to a reference plane, which is a vertical plane perpendicular to the left and right directions. The opposite sides of the two rear fork plates 21 are vertical planes perpendicular to the left and right directions, and the side of the rear footrest 3 facing the rear fork plate 21 is in contact with this vertical plane.
[0034] In some embodiments, the rear footrest 3 further includes a metal bracket 31 and a non-metallic housing 32. The metal bracket 31 is connected to the rear fork plate 21, and the non-metallic housing 32 is connected to at least one of the metal bracket 31 and the rear fork plate 21. The top surface of the metal bracket 31 abuts against the non-metallic housing 32. On a projection plane perpendicular to the vertical direction, the projected area of the upper surface of the non-metallic housing 32 is greater than the projected area of the metal bracket 31.
[0035] After the metal bracket 31 is connected to the rear fork plate 21, the connection strength between the two is high, and the metal bracket 31 can support a greater weight without deforming relative to the rear fork plate 21. At the same time, by setting a non-metallic shell 32 to be connected to at least one of the metal bracket 31 and the rear fork plate 21, and making the upper surface area of the non-metallic shell 32 larger than the upper surface area of the metal bracket 31, on the one hand, the contact area between the passenger's feet and the rear footrest 3 is increased, making the passenger's feet less likely to be uncomfortable and improving riding comfort; on the other hand, the size of the metal bracket 31 can be made smaller, and the weight and cost of the rear footrest 3 are lower.
[0036] Specifically, the two metal brackets 31 are arranged in a mirror-symmetric manner relative to the reference plane, and the two non-metallic shells 32 are arranged in a mirror-symmetric manner relative to the reference plane. The non-metallic shells 32 can be injection-molded plastic parts with a lower hardness than the metal brackets 31. They at least cover the upper surface of the metal brackets 31, effectively improving the appearance of the rear partition.
[0037] In some embodiments, the rear footrest 3 further includes a first buckle 33 and a second buckle 34. The first buckle 33 is connected to the metal bracket 31 and is spaced apart from the rear fork plate 21 in the left-right direction. The second buckle 34 is connected to the non-metallic housing 32 and is disposed between the first buckle 33 and the rear fork plate 21.
[0038] By setting the second buckle 34 between the first buckle 33 and the rear fork plate 21, the non-metallic housing 32 and the rear fork plate 21 are relatively fixed in the left and right directions. At this time, the pre-positioning of the non-metallic housing 32 relative to the rear fork plate 21 can be effectively achieved, which facilitates the further connection of the non-metallic housing 32 with the rear fork plate 21 or the metal bracket 31.
[0039] For example, such as Figure 2 and Figure 5As shown, the first buckle 33 is an L-shaped plate, which is welded to the front side of the metal bracket 31. The second buckle 34 is integrally injection molded with the non-metallic shell 32. During the specific assembly, the non-metallic shell 32 is first moved in the left and right direction and abuts against the rear fork plate 21. Then it is moved backward until the second buckle 34 is engaged between the first buckle 33 and the rear fork plate 21. At this time, the positioning of the non-metallic shell 32 on the rear fork plate 21 is completed, which facilitates the further connection of the non-metallic shell 32 to the rear fork plate 21.
[0040] In some embodiments, the rear fork plate 21 is provided with a first mounting hole 211, and the non-metallic housing 32 is provided with a second mounting hole 321. The non-metallic housing 32 and the rear fork plate 21 are connected by a first fastener passing through the first mounting hole 211 and the second mounting hole 321.
[0041] The non-metallic shell 32 is connected to the rear fork plate 21 by the first fastener, which effectively improves the connection strength between the non-metallic shell 32 and the rear fork plate 21. When the passenger presses on the non-metallic shell 32, the metal bracket 31 and the rear fork plate 21 work together to support the non-metallic shell 32. The rear footrest 3 is more firmly installed on the rear fork plate 21 and has stronger support.
[0042] For example, such as Figure 1 and Figure 5 As shown, both the first mounting hole 211 and the second mounting hole 321 are smooth holes. The first fastener includes a bolt and a nut. The bolt passes through the second mounting hole 321 and the first mounting hole 211 and is threadedly connected to the nut. The nut can be a welded nut welded to the inside of the rear fork plate 21. There are two first mounting holes 211, which are spaced apart in the front-rear direction and are located below the metal bracket 31. The inner surface of the non-metallic housing 32 is provided with a support post extending in the left-right direction. The end face of the support post facing the rear fork plate 21 has a second mounting hole 321. After the non-metallic housing 32 is connected to the rear fork plate 21, the support post abuts against the rear fork plate 21.
[0043] In some embodiments, the non-metallic housing 32 has a countersunk hole 322 communicating with the second mounting hole 321 on the side opposite to the metal bracket 31, and the head of the first fastener is located in the countersunk hole 322.
[0044] By concealing the bolt head within the countersunk hole 322, the rear foot 3 has a more aesthetically pleasing appearance, and the bolt is less likely to loosen or fall off due to external impacts. The connection strength and reliability between the rear foot 3 and the rear fork plate 21 are also higher.
[0045] For example, such as Figure 3 and Figure 4 As shown, there are two countersunk holes 322, which are spaced apart along the front-to-back direction.
[0046] In some embodiments, the upper surface of the non-metallic housing 32 is provided with a plurality of anti-slip ridges 323 or a plurality of anti-slip dots.
[0047] This effectively increases the friction between the non-metallic shell 32 and the passenger's feet, making it less likely for the rear passenger's feet to slip when they act on the non-metallic shell 32, thus improving the safety of the rear passenger.
[0048] like Figures 3-4 As shown, the upper surface of the non-metallic shell 32 is provided with multiple anti-slip protrusions. The multiple anti-slip protrusions extend in the same direction, and the extension direction of the multiple anti-slip protrusions is at an angle to the left and right directions.
[0049] In some embodiments, the non-metallic housing 32 and the metal support 31 abut against and surround to form a receiving cavity, with the metal support 31 located within the receiving cavity.
[0050] In other words, the non-metallic shell 32 separates the metal bracket 31 from the outside world, which not only improves the aesthetics of the rear foot 3, but also effectively reduces the chance of the metal bracket 31 being corroded by external rainwater, thus extending the service life of the rear foot 3.
[0051] In some embodiments, the metal bracket 31 is welded to the rear fork plate 21, or the metal bracket 31 is connected to the rear fork plate 21 by a second fastener.
[0052] The metal bracket 31 can be welded to the rear fork plate 21 to ensure reliable installation of the metal bracket 31 on the rear fork plate 21 and to prevent the rear foot 3 from falling off. The metal bracket 31 can also be detachably connected to the rear fork plate 21 by a second fastener, which makes it easy to install and remove the rear foot 3 from the rear fork plate 21.
[0053] like Figure 1 and Figure 2 As shown, the metal bracket 31 and the rear fork plate 21 are in contact with each other on their opposite sides and are welded together.
