[0037] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0038] Please see Figure 1 The bicycle 1000 of this utility model includes a bicycle rack assembly 100 and a frame 200. The frame 200 includes a frame 210 and a head tube 220 mounted in the head tube 211 of the frame 210. Optionally, in... Figure 1In the middle, the upright 221 of the front end 220 is inserted vertically into the head tube 211 of the frame 210, as shown in the figure. Figure 1 As shown.

[0039] Combined Figures 2 to 7 The bicycle rack assembly 100 includes a connector 10 and a bicycle rack 20. The connector 10 is used to detachably connect the bicycle rack 20 to the bicycle frame 200. The connector 10 includes a base 11 for assembly with the bicycle frame 200. Optionally, it is... Figure 1 In this example, the seat 11 is mounted on the head tube 211, which provides stability to the seat 11. Obviously, depending on actual needs, the seat 11 can also be mounted on the upright 221 of the front of the vehicle 220; therefore, it is not considered... Figure 1 The image shown is for illustrative purposes only. The seat 11 is equipped with a sliding sleeve structure 12 along which the bicycle rack 20 is inserted or removed, and an elastic arm 13. The first end 131 of the elastic arm 13 is connected to the seat 11, which provides stability. The second end 132 of the elastic arm 13 is suspended. The elastic arm 13 has a locking part 14 for locking the bicycle rack 20 inserted into the sliding sleeve structure 12. The bicycle rack 20 is equipped with a matching structure 21 for engaging with the sliding sleeve structure 12 and a locking part 22 for engaging with the locking part 14. The cooperation of the matching structure 21 and the sliding sleeve structure 12 allows the bicycle rack 20 to... Figure 6 The bicycle rack 20 can be inserted downwards into the seat 11 or removed upwards from the seat 11. Furthermore, the locking part 14, when inserted into the seat 11, locks the bicycle rack 20 in place, ensuring the stability between the bicycle rack 20 and the seat 11. Additionally, the locking part 14 can be released by the elastic deformation of the elastic arm 13, facilitating the disassembly of the bicycle rack 20. More specifically, as follows:

[0040] like Figure 8 and Figure 11 As shown, as an example, the base 11 has a first end face 111 and a second end face 112 arranged opposite to each other, and surrounding side faces 113 located between the first end face 111 and the second end face 112. Furthermore, in Figure 10 In this design, the sliding sleeve structure 12 protrudes laterally from the side surface 113 of the seat 11 to increase the support dimension of the sliding sleeve structure 12 on the bicycle rack 20, effectively improving the load-bearing capacity of the seat 11 on the bicycle rack 20. Furthermore, in... Figure 9 and Figure 10In this example, the sliding structure 12, with its two sides 121 spaced upwards on either side of the seat 11, is arranged with a gradually increasing inclination along the insertion direction of the bicycle rack 20 (see arrow A). This design facilitates the insertion of the bicycle rack 20 into the seat 11 along the sliding structure 12 and also allows the sliding structure 12 to bear the load of the bicycle rack 20, thereby increasing the load-bearing capacity of the seat 11 on the bicycle rack 20. Figure 5 In this example, the locking part 14 is an inclined protrusion that protrudes from the first end face 111 of the seat 11 along the insertion direction of the bicycle rack 20. This design makes it easier for the bicycle rack 20 to push the locking part 14 during insertion along the sliding sleeve structure 12, causing the elastic arm 13 to elastically deform and reach the position where the locking part 14 locks with the locking part 22. This allows the locking part 14 to automatically lock with the locking part 22 under the restoring force of the elastic arm 13, further improving the ease of assembly of the bicycle rack 20. It should be noted that when the locking part 12 is an inclined protrusion, the corresponding locking part 22 is a slotted structure; furthermore, the matching structure 21 is a fitting cavity with the opening 211 facing downwards, as shown in the diagram. Figure 7 As shown.

[0041] Combination Figure 5 and Figure 11 As an example, the seat 11 also has a clearance cavity 114, with the openings 1141 of the clearance cavity 114 located on the four sides 113 and the first end face 112 of the seat 11. The elastic arm 13 is partially located in the clearance cavity 114, and the second end 132 of the elastic arm 13 extends out of the seat 11 from the opening 1141 on the four sides 113 of the seat 11. For example, in… Figure 5 In the middle, the second end 132 of the elastic arm 13 extends from below into the seat 11, but not... Figure 5 As shown, the locking part 14 protrudes from the cavity 1141 on the first end face 111 of the seat body 11, as shown in the figure. Figure 5 As shown; this design makes the arrangement between the elastic arm 13 and the seat 11 more compact. Furthermore, in Figure 8 , Figure 9 and Figure 11 As an example, the base 11 also has perforated grooves 115 that are spaced apart from each other and penetrate the first end face 111 of the base 11. The perforated grooves 115 are also arranged around and spaced apart from the cavity 1141 on the first end face 111 of the base 11. Furthermore, in... Figure 5 , Figure 6 and Figure 10As an example, the base 11 also has mounting holes 116 arranged through the first end face 111 and the second end face 112 in opposite directions (see the direction indicated by arrow C or the opposite direction) for fasteners to fix the base 11 to the vehicle body 200. The number of mounting holes 116 can be [number missing]. Figure 5 , Figure 6 and Figure 10 As shown in the three examples, it is clear that the number of mounting holes 116 may also be two or four. Thus, by means of the corresponding number of fasteners (such as, but not limited to, high-strength screws) and the cooperation of mounting holes 116, the seat 11 is rigidly connected to the vehicle body 200 (such as head tube 211), thereby ensuring reliable load-bearing and no swaying during riding.

[0042] In order to make the seat 11 fit more tightly with the head tube 211 of the vehicle body 200, Figure 4 As an example, the second end face 112 of the seat 11 has an arcuate surface 1121 for engaging with the vehicle body 200. To facilitate the passage of fasteners through the mounting holes 116, [the following is omitted]. Figure 11 In this example, the first end 131 of the elastic arm 13 is detachably connected to the base 11, for example, by using fasteners 18 to assemble the first end 131 of the elastic arm 13 to the base 11. Obviously, depending on actual needs, other detachable assembly methods between the first end 131 of the elastic arm 13 and the base 11 are also well-known in the art, and will not be elaborated here. To facilitate the operator's unlocking and releasing operation of the locking part 14, in... Figures 2 to 12 In this example, the second end 132 of the elastic arm 13 is provided with a traction rope 15. The traction rope 15 pulls the elastic arm 13 to make elastic deformation, thereby releasing the locking part 14; specifically, in conjunction with Figures 2 to 12 As an example, the second end 132 of the elastic arm 13 has a through hole 133, the traction rope 15 is an open loop with both ends 15a, and each end 15a of the traction rope 15 has a mounting hole 151. A shaft 16 with a limiting head 161 passes through the through hole 133 and the mounting hole 151 of at least one end 15a of the traction rope 15. A screw 17 is threadedly connected to the shaft 16 so that the second end 132 of the elastic arm 13 and the two ends 15a of the traction rope 15 are limited between the limiting head 161 and the screw 17. See the diagram. Figure 9 and Figure 10 As shown, this facilitates the assembly of the traction rope 15 with the second end 132 of the elastic arm 13, and also allows the traction rope 15 to rotate relative to the second end 132 while pulling the elastic arm 13, thus reducing operating effort. It should be noted that when the traction rope 15 is mounted on the second end 132 of the elastic arm 13, the traction rope 15 can wrap around the crossbeam 212 extending in the front-rear direction of the frame 210, as shown in the diagram. Figure 1 As shown.

[0043] like Figures 1 to 7 As shown, as an example, the bicycle rack 20 includes a support bracket 20a and a side support bracket 20b fixedly connected to the support bracket 20a. Optionally, in Figure 1 In this configuration, the angle between the side support bracket 20b and the support bracket 20a is greater than or equal to 80 degrees and less than 90 degrees, so that the bicycle rack 20 is approximately "L" shaped. At this time, the matching structure 21 is located on the side support bracket 20a with the cavity opening 211 facing downwards in the mounting cavity, and the locking part 22 is located on the cavity wall 212 of the mounting cavity (see...). Figure 7 On the bicycle rack 20, which is roughly "L" shaped, together with the tow rope 15, the bicycle rack assembly 100 looks like a pig's nose.

[0044] In summary, by pulling the traction rope 15, the elastic arm 13 can be retracted, causing the locking part 14 on the elastic arm 13 to disengage from the bicycle rack 20, achieving one-handed, quick disassembly without the need for tools, thus achieving the purpose of one-click quick disassembly. When installing the bicycle rack 20, simply slide the bicycle rack 20 along the sliding sleeve structure 12; the locking part 14 on the elastic arm 13 automatically locks due to the rebound force of the elastic arm 13, accompanied by a "click" sound, preventing the bicycle rack 200 from loosening. The installation process is quick, achieving the purpose of automatic locking installation. Furthermore, the connecting seat 10 can be made of plastic, allowing for customized molding to match specific bicycle models.

[0045] Compared with the prior art, the bicycle rack 20 can be quickly installed on or removed from the seat 11 by means of the sliding sleeve structure 12 provided on the seat 11; by means of the elastic arm 13 with the first end 131 connected to the seat 11 and the second end 132 suspended, and the locking part 14 provided on the elastic arm 13, the elastic arm 13 is elastically deformed during the installation of the bicycle rack 20 into the seat 11 and comes to the position locked by the locking part 14, ensuring the stability of the bicycle rack 20 installed on the seat 11. In addition, the operator can unlock the locking part 14 by operating the elastic arm 13 with one hand; therefore, no tools are required for installation and removal, thus realizing the quick installation and removal of the bicycle rack 20 from the bicycle frame 200 of the bicycle 1000.

[0046] It should be noted that the bicycle rack component 100 is applicable to the following scenarios: (1) the bicycle rack 20 needs to be frequently disassembled due to reasons such as, but not limited to, entering and exiting elevators, storing vehicles, etc.; (2) quickly switching between cargo-carrying and lightweight states during cycling trips; (3) making cycling more free and cargo-carrying easier.
