[0023] Embodiment

[0024] Please refer to Figures 1-6 , as shown in the figure, there is a lock 2 with a tail lamp 1 and a fixing bracket 3 for fixing the lock 2 on the vehicle frame. This product is mainly used for bicycles. It should be noted that the connection structure between the lock 2 and the tail lamp 1 in this embodiment. The connection structure includes the main body of the lock 2 and the tail lamp 1 detachably connected to the main body of the lock 2. At one end of the tail lamp 1 connected to the lock 2, there is a first insertion end 11 inserted into the lock 2. At least two first convex bumps 12 extend radially from the edge position of the first insertion end 11. Corresponding to this, on the lock 2, there is a first recessed portion 21 for the first insertion end 11 of the tail lamp 1 to be inserted. The inner wall of the first recessed portion 21 is provided with a first lip 22 extending radially inward. On the first lip 22, there are first notches 23 corresponding to the positions and quantities of the first convex bumps 12 of the tail lamp 1. After the first insertion end 11 of the tail lamp 1 is inserted into the first recessed portion 21 of the lock 2, it is rotated so that the first lip 22 of the lock 2 catches the first convex bumps 12 of the tail lamp 1. In this embodiment, the extending length of the first convex bumps 12 should be controlled within the range where the first recessed portion 21 is located.

[0025] A first positioning mechanism for preventing relative rotation between the lock 2 and the tail lamp 1 is provided between the first recessed portion 21 of the lock 2 and the first insertion end 11 of the tail lamp 1. The first positioning mechanism includes a first elastic piece 24 provided on the end face of the first recessed portion 21. A first positioning protrusion 241 is provided on the first elastic piece 24. A first groove 13 for the first positioning protrusion 241 of the first elastic piece 24 to snap into is provided on the end face of the corresponding first insertion end 11. When the tail lamp 1 is installed on the lock 2, the tail lamp 1 is rotated to make the first positioning protrusion 241 on the first elastic piece 24 snap into the first groove 13 of the tail lamp 1 to position the tail lamp 1. A space for the elastic movement of the first elastic piece 24 is provided between the back surface of the first elastic piece 24 where the first positioning protrusion 241 is provided and the adjacent parts. The setting of the positioning mechanism enables the elastic and firm cooperation between the tail lamp 1 and the lock 2, preventing shaking. When jolting, the first elastic piece 24 can play a buffering role, not only will it not fall off, but almost no noise will be generated either.

[0026] The side surface of the first positioning protrusion 241 that contacts the first groove 13 during rotation is a slope surface, or the inner wall of the first groove 13 that contacts the first positioning protrusion 241 during rotation is a slope surface. The design of the slope surface enables the first positioning protrusion 241 and the first groove 13 to be disengaged when either part is rotated with a little force.

[0027] When the tail lamp 1 and the lock 2 are docked, first align the first convex 12 with the first notch 23 and insert them. Then rotate the tail lamp 1 so that the first convex 12 rotates to be blocked by the first lip 22. Then rotate to make the first positioning protrusion 241 of the first elastic piece 24 snap into the first groove 13 of the tail lamp 1, realizing the assembly of the tail lamp 1 and the lock 2. When disassembling, only need to rotate the tail lamp 1 with a little force, so that the inner wall of the slope surface of the first groove 13 of the tail lamp 1 pushes against the first positioning protrusion 241 during rotation. Due to the effect of the slope surface, the first elastic piece 24 is forced to deform. Continuing to rotate can cause the first positioning protrusion 241 and the first groove 13 to be disengaged. Then continue to rotate the tail lamp 1 to make the position of the first convex 12 correspond to the position of the first notch 23. At that time, the tail lamp 1 can be axially pulled out. In this embodiment, the disassembly and assembly of the tail lamp 1 are very convenient and fast.

[0028] The connection structure between the other end of the lock 2 and the fixing bracket 3 in this embodiment is the same as the connection structure between the lock 2 and the tail light 1. Specifically, the fixing bracket 3 is fixed to the vehicle frame. At one end of the fixing bracket 3 connected to the lock 2, there is a second insertion end 31 inserted into the lock 2. At least two second locking protrusions 32 radially extend from the edge position of the second insertion end 31. Corresponding to this, on the lock 2, there is a second recess 25 for the second insertion end 31 of the tail light 1 to be inserted. On the inner wall of the second recess 25, there is a second lip 26 extending radially inward. On the second lip 26, there are second notches 27 corresponding to the positions and quantities of the second locking protrusions 32 of the tail light 1. After the second insertion end 31 of the tail light 1 is inserted into the second recess 25 of the lock 2, it is rotated so that the second lip 26 of the lock 2 catches the second locking protrusion 32 of the tail light 1. A second positioning mechanism for preventing relative rotation between the lock 2 and the tail light 1 is provided between the second recess 25 of the lock 2 and the second insertion end 31 of the tail light 1. The second positioning mechanism includes a second elastic sheet 28 provided on the end face of the second recess 25. The second elastic sheet is fixedly installed on the lock. On the second elastic sheet 28, there is a second positioning protrusion 281. Corresponding to this, on the end face of the second insertion end 31, there is a second groove 33 for the second positioning protrusion 281 of the second elastic sheet 28 to be snapped into. When the tail light 1 is installed on the lock 2, the tail light 1 is rotated so that the second positioning protrusion 281 on the second elastic sheet 28 is snapped into the second groove 33 of the tail light 1 to position the tail light 1. In this embodiment, there are two second locking protrusions and they are symmetrically arranged about the center. There are two second elastic sheets or two second positioning protrusions are arranged on one second elastic sheet, and the two second positioning protrusions are also symmetrically arranged about the center. The center referred to by the above-mentioned central symmetry is the axis line of the lock. In this embodiment, the lock as a whole has a cylindrical structure. There is a space for the elastic movement of the second elastic sheet 28 between the back surface of the second elastic sheet 28 provided with the second positioning protrusion 281 and the adjacent parts. The side surface of the second positioning protrusion 281 in contact with the second groove 33 during rotation is a slope surface, or the inner wall of the second groove 33 in contact with the second positioning protrusion 281 during rotation is a slope surface. The disassembly and assembly method between the lock 2 and the fixing bracket 3 is the same as the disassembly and assembly method between the lock 2 and the tail light 1, and will not be repeated here.
