Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 A rear rack extension bracket for a two-wheeled vehicle includes a bracket body detachably connected to the rear rack 2 of the two-wheeled vehicle. Multiple support bars are spaced apart along the front-rear direction on the upper end of the bracket body. Preferably, the support bars in this embodiment are made of CNC aluminum profiles and welded to the bracket body. Alternatively, the support bars can be cast into the bracket body. The rear rack extension bracket 1 works in conjunction with the rear rack 2, extending the effective carrying area of ​​the rear rack 2 rearward. The multiple support bars form a quick-release mechanism, allowing for the use of different accessories, thus increasing the cargo space of the rear rack 2 and enabling it to carry more items.

[0029] Continue reading Figures 1-4 In one embodiment of this utility model, the shelf body is mainly formed by bending and welding multiple aluminum tubes. The shelf body includes a lower shelf 100 and an upper shelf 101 connected to the upper end of the lower shelf 100. A connecting support component is provided between the upper shelf 101 and the lower shelf 100. Both the lower shelf 100 and the upper shelf 101 are tubular frame structures. The lower shelf 100 has a reinforcing tube 1002 that is transversely connected between the left and right side tubes of the lower shelf 100.

[0030] Continue reading Figure 3In one embodiment of this utility model, a first connecting hole 1000 is provided on the left and right sides of the front end of the lower shelf 100, and a second connecting hole 1001 is provided on the left and right sides of the middle part of the lower shelf 100. Both the first connecting hole 1000 and the second connecting hole 1001 are connected to the rear shelf 2 by screws. The screws can be tightened from bottom to top or from top to bottom. It should be noted that the number and position of the connecting holes in this utility model can be adjusted as needed.

[0031] In another embodiment of this utility model, the bracket body can also be installed with the rear shelf 2 by snap-fitting, specifically by using left and right snap-fitting or front and back snap-fitting to snap onto the side of the rear shelf 2.

[0032] Continue reading Figure 4 In one embodiment of this utility model, the upper shelf 101 is positioned further back than the lower shelf 100.

[0033] Continue reading Figures 1-4 In one embodiment of this utility model, a fixing hook 102 is provided at the lower middle part of the lower shelf 100. The fixing hook 102 is located in front of the reinforcing tube 1002 and is used to limit the connection with the crossbar on the rear shelf 2. Specifically, the fixing hook 102 has a U-shaped structure with the hook opening facing backward.

[0034] Continue reading Figure 2 and Figure 4 In one embodiment of this utility model, an anti-slip pad 103 is provided on the hook surface of the fixing hook, and the fixing hook 102 contacts the crossbar of the rear rack 2 through the anti-slip pad 103. The anti-slip pad 103 can be made of materials such as rubber, silicone, or sponge, and is used to increase friction during installation, making it easier to tighten the screws when fixing the rear rack extension bracket 1 to the rear rack 1, preventing slippage, and providing a certain buffer when the vehicle vibrates after tightening. If the screws are slightly loose, vibration reduction can also prevent them from loosening quickly.

[0035] In another embodiment of this utility model, an anti-slip pad 103 can also be provided on the crossbar of the rear shelf 2 corresponding to the fixing hook 102, and the fixing hook 102 contacts the crossbar of the rear shelf 2 through the anti-slip pad 103.

[0036] Continue reading Figures 1-4 In one embodiment of the present invention, the support bar is provided with through holes 107 for installing two-wheeled vehicle accessories in part or all, and the support bar is provided with groove structures for installing two-wheeled vehicle accessories in part or all.

[0037] Furthermore, the support bars are divided into front support bars 104, middle support bars 105, and rear support bars 106, spaced apart as needed. Each of the front support bars 104, middle support bars 105, and rear support bars 106 has a through hole 107 on the left and right sides. Both the front support bars 104 and rear support bars 106 have groove structures. The through holes 107 are preferably screw holes, used to connect other accessories, such as shelves or quick-release devices. The groove structures are used to connect with the quick-release devices. The quick-release device is a plate-like structure and serves as the basic fixing mechanism. Other accessories, such as baskets or seats, can be connected to it. The quick-release device has several mounting holes corresponding to the through holes 107. The through holes and mounting holes are connected by bolts. The front and rear ends of the quick-release device each have protruding structures for positioning. In addition to the protruding structures, the front and rear ends of the quick-release device also have locking tongues.

[0038] Specifically, a vertically extending front support bar positioning groove 1040 is provided on the rear side of the front support bar 104. The front support bar positioning groove 1040 is a rectangular groove (or other shapes as needed). A front support bar retaining groove 1041 is provided at the bottom of the front support bar 104. The front support bar retaining groove 1041 is also a rectangular groove (or other shapes as needed). The front support bar retaining groove 1041 is located in front of the front support bar positioning groove 1040, and its length in the left-right direction is less than the length in the left-right direction of the front support bar positioning groove 1040. The front support bar retaining groove 1041 communicates with the front support bar positioning groove 1040. The front support bar positioning groove 1040 limits the quick-release device in the front-back and left-right directions on the horizontal plane. The front support bar retaining groove 1041 is used to fix the locking tongue at the front end of the quick-release device, and limits the quick-release device in the vertical and left-right directions. The front side of the rear support bar 106 is provided with a vertically extending rear support bar positioning groove 1060, which is rectangular (or can be other shapes as needed). The rear bottom of the rear support bar 106 is provided with a rear support bar locking tongue groove 1061, which is also rectangular (or other shapes as needed). It has two openings, located at the rear and bottom of the locking tongue groove 1061, respectively. The length of the locking tongue groove 1061 in the left-right direction is less than the length of the positioning groove 1060 in the left-right direction. The positioning groove 1060 limits the forward, backward, left, and right directions of the quick-release device in the horizontal plane. The locking tongue groove 1061 is used to fix the locking tongue at the rear end of the quick-release device, limiting the vertical and horizontal directions of the quick-release device.

[0039] It should be noted that the shape, size, and position of the groove structure on the front support bar 104 and the rear support bar 106 can be adjusted according to the corresponding structure of the quick-release device.

[0040] The intermediate support bar 105 is an optional accessory; in other embodiments, the intermediate support bar 105 may not be provided.

[0041] Please see Figures 5-7 This utility model also provides a shelving device, including a rear shelf 2, with a rear shelf extension bracket 1 as described above disposed at the rear end of the rear shelf 2. The rear shelf extension bracket 1 is disposed in the middle or rear side of the rear shelf 2, and a portion of the rear shelf extension bracket 1 can extend to the outside of the rear shelf 2. It should be noted that the length of this rear shelf 2 is longer than that of the rear shelves of the prior art, and it can accommodate up to two sets of quick-release devices.

[0042] Normally, the rear rack extension bracket 1 is installed at the rear of the rear rack 2. In some scenarios where it is necessary to increase the load height (such as when the bottom of the pannier is low and may rub against the ground when turning), the rear rack extension bracket 1 can increase the initial load height of the items. In this case, the rear rack extension bracket 1 is not limited to being placed at the rear of the rear rack 2.

[0043] like Figure 7 As shown, in one embodiment of this utility model, the rear shelf extension bracket 1 is installed on the rear shelf 2 in an inclined state with the front lower and the rear higher.

[0044] It should be noted that the rear rack extension bracket 1 of this utility model can be used for carrying goods. In some countries and regions where this utility model is exported, due to legal and social customs, two child seats can be installed on the rear rack 2. However, in the conventional way, the front child seat is relatively close to the bicycle seat, and the rider may hit the foot pedal of the child seat with their heel while riding, causing a safety hazard. Therefore, it is necessary to move the installation position of the child seat back. At this time, the remaining space on the rear rack 2 cannot be used to install a second child seat or other items. Therefore, the rear rack extension bracket 1 provided by this utility model can expand the carrying range of the rear rack 2, thereby installing a second set of child seats or other storage space. Furthermore, when two sets of child seats are installed, the rear child seat is positioned higher, which facilitates forward visibility and reduces the danger caused by children sticking their heads out to the side out of curiosity.

[0045] Meanwhile, to better accommodate the installation of other accessories at the rear when a child seat is installed in front, the upper shelf 101 and the lower shelf 100 of this utility model are staggered, with the upper shelf 101 positioned further back than the lower shelf 100. This is because if the upper shelf 101 and the lower shelf 100 are on the same vertical plane, the front seat will be difficult to install due to the mounting mechanism at the bottom rear of the seat, and the seat itself also has a certain backward tilt angle, which may cause inconvenience to children using the rear seat. Therefore, by setting the upper shelf 101 to be staggered relative to the lower shelf 100, this problem can be avoided.

[0046] The rear rack 2 of this utility model adopts a rearward tilting structure, and the overall shape of the rear rack extension bracket 1 is the same, making it easy to process. The grooves and screw holes are consistent, and the screws are interchangeable. Furthermore, because the center of gravity of the rear seat does not extend too far backward, even when the front is unloaded, tests have shown that placing a 75kg counterweight on the rear rack extension bracket 1, which is installed at the rear end of the rear rack 2 and extends outward, will not cause the vehicle to tilt, thus ensuring safety during driving.

[0047] This utility model also provides a two-wheeled vehicle, which includes the rack device described above.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
