Abstract
Description
Technical Field
[0001] The utility model relates to the field of transportation, in particular to a connecting mechanism for modular frames of small and light vehicles such as bicycles, scooters, tricycles, etc. Background Art
[0002] According to the utility model patent "A modular frame connection mechanism", application number 201520179058.7, the disclosed modular frame connection mechanism includes a sleeve and an independent axle tube. The axle tube will add a lot of extra weight to the vehicle and does not have the function of locking the connection between frame modules. Summary of the invention
[0003] The utility model aims to provide a docking mechanism for a modular frame, through which independent frame modules are connected, so that a user can easily disassemble the frame or replace any frame module. At the same time, the docking mechanism of the modular frame has a simpler structure and lighter weight, and has the function of locking the connection between frame modules.
[0004] The technical solution adopted by the utility model to solve its technical problems is: the docking mechanism of the modular frame comprises at least one sleeve and at least one insert, which are respectively fixed to the docking ends of two frame modules to be connected, the sleeve and the insert are both tubular structures, and the insert can be inserted into the sleeve; an opening is provided on the tube wall of the sleeve, and a screw locking mechanism or a quick-release locking mechanism is installed on the sleeve; a lock core is installed on the sleeve or the insert, and when the lock core is in a locked state, the lock tongue of the lock core interferes with the other end frame module of the docking to prevent the frame module from being maliciously disassembled; at least one hole is respectively provided on the tube wall of the sleeve and the insert, and a bayonet is inserted into the hole on the tube wall of the sleeve or the insert, and when the insert is inserted into the sleeve, the bayonet simultaneously passes through the holes on the tube walls of the sleeve and the insert to play a positioning role.
[0005] The beneficial effects of the utility model are: positioning and connection between frame modules are realized with a relatively simple structure, and the connection can be locked to prevent the frame modules from being maliciously disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0011] The bicycle frame in the embodiment is composed of two independent frame modules. The connecting mechanism of the modular frame is used near the head tube, which includes a sleeve (1) and an insertion tube (2). The sleeve (1) is provided with an opening at the edge and is equipped with a quick-release locking mechanism (3). A lock core (4) is installed on the tube wall of the sleeve (1). A hole is provided on the tube wall of the insertion tube (2). A bayonet (5) is inserted into the hole. The bayonet (5) is connected to the insertion tube (2) through a spring. A cross bar is fixed at the tube mouth of the insertion tube (2). When the insertion tube (2) is inserted into the sleeve (1), the bayonet (5) simultaneously passes through the holes on the sleeve (1) and the tube wall of the insertion tube (2) to play a positioning role. The quick-release locking mechanism (3) is locked to tighten the insertion tube (2). The lock core (4) is locked so that the lock tongue interferes with the cross bar at the tube mouth of the insertion tube (2), thereby preventing the frame module from being maliciously disassembled. Thus, the user can remove the insertion tube (2) from the sleeve (1) by unlocking the lock cylinder (4), loosening the quick-release locking mechanism (3), and pressing the latch (5), thereby being able to remove the frame module, making the vehicle easy to carry, or replacing modules with different functions. The docking mechanism of the modular frame is relatively simple in structure, light in weight, and has the function of locking the connection between frame modules.
