[0009] Furthermore, the handle passes through the U-shaped plate, and the U-shaped plate has a guide groove that mates with the handle.

[0010] Furthermore, the handle is provided with a limiting groove that mates with the U-shaped plate.

[0011] Furthermore, the base plate also includes straight plates that are connected to the two base rods respectively, and the U-shaped plate is connected to the two straight plates respectively.

[0018] Furthermore, the top wall of the first fixing rod and the bottom wall of the second fixing rod are respectively provided with fixing grooves that cooperate with the traction rod.

[0019] Another objective of this invention is to provide a bicycle bracket that includes the aforementioned handle concealed folding mechanism.

[0020] In summary, this utility model has the following beneficial effects: 1. The inner receiving cavity is formed on the inner side of the folding base frame. The handle is arranged in the inner receiving cavity, so that the handle is recessed at the far end of the folding base frame, realizing the hidden arrangement of the handle, reducing the risk of the handle failing after being hit, and also preventing the handle from being accidentally operated and thus unlocking, thereby improving safety. 2.

The guide groove and the limiting groove work together to achieve multiple limiting, which not only limits the direction of movement of the handle, but also prevents the handle from falling off; 5. The detachable connection between the handle and the lever, and the detachable connection between the pull plate and the locking plate, are mainly to facilitate the installation of the locking mechanism onto the folding base frame, and of course, to facilitate the disassembly and maintenance of the locking mechanism. 6. The use of protective tubes serves two purposes: firstly, the extension tube guides and limits the pull rod, and secondly, it protects the locking spring, preventing debris from getting stuck inside and affecting its contraction. It also prevents the locking spring from coming into contact with rainwater, thus extending its service life. 7. The bottom rod is a hollow square tube with a liner embedded in the guide slot that contacts the locking plate. This prevents the locking plate from being worn into grooves, which would affect its movement and thus extend the stability and service life of the folding mechanism. 8. After disengaging the locking plate from the first locking slot, rotate the folding frame downwards until the locking plate contacts the stop surface. At this point, the folding frame is in a downward swing state relative to the fixed bracket. This facilitates the installation and removal of the bicycle and prevents the far end of the folding frame from contacting the ground, thus providing protection. The downward swing state is a temporary state, so using the stop surface not only simplifies the structure of the fixed bracket and facilitates processing, but also allows the folding frame to be automatically locked to the unfolded state simply by rotating it upwards, making operation convenient and optimizing the user experience.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example 1:

[0026] Reference Figure 1 and Figure 2In this embodiment, the far end of the folding base frame 2 is provided with an inner receiving cavity 24 for hiding the handle 31. The inner receiving cavity 24 is formed inside the folding base frame 2. The handle 31 is arranged in the inner receiving cavity 24, so that the handle 31 is recessed at the far end of the folding base frame 2, thereby hiding the handle 31, reducing the risk of the handle 31 failing after being hit, and also preventing the handle 31 from being accidentally unlocked. Since the handle 31 can move relative to the folding base frame 2, the handle 31 is hidden at least in the locked state. Preferably, in this embodiment, the handle 31 is hidden in both the locked and unlocked states.

[0027] Reference Figure 1 and Figure 2 Preferably, the far end of the folding base frame 2 is provided with an opening communicating with the inner receiving cavity 24, so as to facilitate operation; the inner receiving cavity 24 needs to include at least one opening for a hand to reach in and grasp the handle 31; the position and number of openings can be adjusted as needed and are not limited here.

[0028] Reference Figure 1 and Figure 2 Specifically, in this embodiment, the folding base frame 2 includes two spaced-apart base rods 21, a plurality of bases 22 fixedly mounted on the two base rods 21, and a base plate 23 disposed between the distal ends of the two base rods 21; wherein, the proximal end of the base rod 21 is rotatably connected to the fixed bracket 1; in this embodiment, the inner receiving cavity 24 is located between the two base rods 21, and the inner receiving cavity 24 is a multi-faceted open chamber; in other optional embodiments, if the folding base frame is a single base rod, the inner receiving cavity is formed inside the base rod; if the folding base frame includes three or more base rods, the inner receiving cavity may be formed between two adjacent base rods.

[0029] Reference Figure 1 and Figure 2 In this embodiment, the folding chassis 2 includes two base rods 21, which can effectively improve the structural strength of the folding chassis 2, thus making it suitable for vehicles with larger weights. In this embodiment, two bases 22 are provided on the base rods 21, which can support two vehicles at the same time. Moreover, the cooperation between the double base rods and the double bases can further improve the structural strength and stability of the folding chassis 2. In this embodiment, the base plate 23 is arranged at the far end of the base rods 21, which can improve the structural strength and stability of the folding chassis 2 on the one hand, and on the other hand, it is used to support the locking mechanism 3.

[0030] Reference Figure 1 and Figure 2In this embodiment, the base plate 23 includes two straight plates 231 and a U-shaped plate 232 connected between the two straight plates 231; the two straight plates 231 are respectively connected to the far ends of the two base rods 21, and the U-shaped plate 232 is located between the two base rods 21; in this embodiment, the inner receiving cavity 24 is located between the two base rods 21, and more specifically, it is located inside the U-shaped plate 232; that is, the U-shaped plate 232 serves as the sidewall of the inner receiving cavity 24, and the inner receiving cavity 24 includes a far end opening and is vertically continuous.

[0031] Reference Figure 1 and Figure 2 In this embodiment, the structure of the base plate 23 not only forms an inner cavity 24 to realize the hidden arrangement of the handle 31, but also supports the locking mechanism 3 and is convenient to connect with the base rod 21. At the same time, the structure is simple and easy to process. In other optional embodiments, the structure of the base plate 23 can also be adjusted as needed, and there are no restrictions here.

[0032] Reference Figures 1 to 6 In this embodiment, the handle 31 moves in a straight line relative to the U-shaped plate 232 to perform the unlocking action. In this embodiment, the U-shaped plate 232 includes two side plates and one end plate. Preferably, both ends of the handle 31 pass through the two side plates of the U-shaped plate 232, and guide grooves 233 that cooperate with the handle 31 are respectively provided on the side plates of the U-shaped plate 232; that is, the handle 31 moves along the guide grooves 233. Preferably, the handle 31 is provided with limiting grooves 311 that cooperate with the side plates of the U-shaped plate 232; that is, the limiting grooves 311 are shaped as follows: A shaft segment with a smaller outer diameter is embedded in the guide groove 233, while the side plate of the U-shaped plate 232 is embedded in the limiting groove 311. The guide groove 233 and the limiting groove 311 cooperate to achieve multiple limiting, which not only limits the movement direction of the handle 31, but also prevents the handle 31 from falling off. Preferably, the end of the guide groove 233 away from the straight plate 231 is provided with an enlarged hole for the handle 31 to pass through, so as to facilitate the installation of the handle 31. After the handle 31 is installed in place, the movement stroke is within the length range of the guide groove 233, so it will not fall off from the enlarged hole.

[0033] Reference Figures 1 to 6In this embodiment, the locking mechanism 3 also includes a pull rod 32, a pull plate 33, a locking spring 35, a limiting plate 36, a protective tube 37, a locking pin 38, and a washer 39. One end of the pull rod 32 is detachably connected to the handle 31, and the other end is fixedly connected to the pull plate 33 by welding. The handle 31 is provided with a bolt that connects to the pull rod 32, so as to achieve a detachable connection. Two sets of bolt and nut assemblies are provided between the pull plate 33 and the locking plate 34, so as to achieve a detachable connection. The detachable connection between the handle 31 and the pull rod 32, and the detachable connection between the pull plate 33 and the locking plate 34, are mainly to facilitate the installation of the locking mechanism 3 onto the folding base frame 2, and of course, to facilitate the disassembly and maintenance of the locking mechanism 3.

[0034] Reference Figures 1 to 6 One end of the protective tube 37 is provided with an extension tube 371 with a smaller outer diameter. The extension tube 371 passes through the end plate of the U-shaped plate 232, and the protective tube 37 is fixedly connected to the U-shaped plate 232. The pull rod 32 passes through the protective tube 37 and the extension tube 371. The pull rod 32 and the extension tube 371 are in clearance fit, and the extension tube 371 plays a guiding and limiting role for the pull rod 32.

[0035] Reference Figures 1 to 6 The protective tube 37 and the handle 31 are located on both sides of the U-shaped plate 232, while the limiting plate 36, the locking spring 35, and the washer 39 are all sleeved on the pull rod 32 and located inside the protective tube 37. A locking pin 38 passes through the limiting plate 36 and the pull rod 32 to achieve a fixed connection, that is, the axial position of the limiting plate 36 relative to the pull rod 32 is fixed. The limiting plate 36 and the washer 39 are located at both ends of the locking spring 35, and the washer 39 contacts the inner end face of the protective tube 37. The elastic force of the locking spring 35 is transmitted to the pull rod 32 through the limiting plate 36 and the locking pin 38, so that the locking plate 34 has a tendency to move into the locking groove, thereby realizing automatic locking and maintaining the locked state. In the locked state, the limiting plate 36 is located inside the protective tube 37. When unlocking, the limiting plate 36 moves inside the protective tube 37, and the movement stroke of the limiting plate 36 is all inside the protective tube 37.

[0036] Reference Figures 1 to 6 The protective tube 37 is used to guide and limit the pull rod 32 through the extension tube 371, and to protect the locking spring 35, preventing debris from getting stuck in the locking spring 35 and affecting its contraction. It also prevents the locking spring 35 from contacting rainwater, thus extending its service life.

[0037] Reference Figures 1 to 6Specifically, the bottom rod 21 is provided with a guide groove 211 that cooperates with the locking plate 34. Preferably, a liner 212 that contacts the locking plate 34 is provided in the guide groove 211. In this embodiment, the guide groove 211 is through-hole, which facilitates the arrangement of the liner 212. The liner 212 is U-shaped, and the two ends of the locking plate 34 are respectively embedded in the two liner 212. In this embodiment, the bottom rod 21 is a hollow square tube. The liner 212 that contacts the locking plate 34 is embedded in the guide groove 211, which can prevent the locking plate 34 from being worn into grooves and affecting its movement, thereby extending the stability and service life of the folding mechanism.

[0038] Reference Figures 1 to 3 In this embodiment, the multiple locking slots include a first locking slot 111 corresponding to the unfolded state and a second locking slot 112 corresponding to the folded state. When the locking plate 34 is embedded in the first locking slot 111, the folding base frame 2 is in an unfolded state relative to the fixed bracket 1, which is used to support the bicycle. When the locking plate 34 is embedded in the second locking slot 112, the folding base frame 2 is in a folded state relative to the fixed bracket 1, which is used to reduce the volume of the folding mechanism.

[0039] Reference Figures 1 to 3 Preferably, in this embodiment, the fixed bracket 1 is also provided with a stop surface 113 that cooperates with the locking plate 34. The stop surface 113 and the second locking groove 112 are respectively located on both sides of the first locking groove 111. Specifically, the second locking groove 112 is located on the upper side of the first locking groove 111, while the stop surface 113 is located on the lower side of the first locking groove 111. After the locking plate 34 is disengaged from the first locking groove 111, the folding base frame 2 is rotated downward until the locking plate 34 contacts the stop surface 113. At this time, the folding base frame 2 is in a downward swing state relative to the fixed bracket 1. This facilitates the installation and disassembly of the bicycle and avoids the far end of the folding base frame 2 from contacting the ground, thus providing protection.

[0040] Reference Figures 1 to 3 The lowered state is a temporary state. Therefore, the use of the stop surface 113 not only simplifies the structure of the fixed bracket 1 and facilitates processing, but also allows the folding base frame 2 to be automatically locked to the unfolded state by simply rotating it upwards, which is convenient for operation and optimizes the user experience.

[0041] Reference Figure 1 and Figure 2In this embodiment, the fixed bracket 1 includes two fixed plates 11, a first fixed rod 12 and a second fixed rod 13 disposed between the two fixed plates 11, and a traction rod 14 connected to the two first fixed rods 12 and the second fixed rod 13 respectively; wherein, the traction rod 14 is used to connect to a car to realize the vehicle-mounted function; preferably, in this embodiment, the first fixed rod 12 and the second fixed rod 13 are staggered relative to the traction rod 14 in the length direction and the height direction respectively, which can effectively improve the structural strength and stability of the fixed bracket 1, thereby enabling it to bear a large weight of bicycle; specifically, the top wall of the first fixed rod 12 and the bottom wall of the second fixed rod 13 are respectively provided with a first fixed slot 121 and a second fixed slot 131 that cooperate with the traction rod 14, thereby further improving the structural strength and stability; in this embodiment, the two bottom rods 21 are rotatably connected to the two fixed plates 11 respectively, and the first locking groove 111, the second locking groove 112 and the stop surface 113 are all disposed on the fixed plate 11.
