DETAILED DESCRIPTION

[0045] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0046] like Figures 1 to 12As shown, a trunk quick-release structure includes a box assembly 2, the lower end of the box assembly 2 is connected to a buckle bottom plate 6, in this embodiment, the buckle bottom plate 6 is connected to the box body 201 by welding, and the buckle bottom plate 6 is detachably connected to the frame connecting plate 7; the frame connecting plate 7 is fixedly connected to the tail frame of the motorcycle, and the buckle bottom plate 6 is fixedly connected to the box assembly 2, so when using it, it is only necessary to slide the buckle bottom plate 6 and the frame connecting plate 7 together, one end of the box assembly 2 is connected to the first lock body 5, and one end of the frame connecting plate 7 is connected to the first lock buckle 4, and the first lock body 5 and the first lock buckle 4 can be locked. When disassembling, it is only necessary to unlock the first lock body 5 and the first lock buckle 4, so that the box assembly 2 can be directly slid off the motorcycle, and the disassembled trunk is a whole, and there is no risk of parts loss. Compared with the traditional method of connecting the trunk to the motorcycle tail rack with bolts or connecting with multiple parts, the trunk quick-disassembly structure of the utility model is more flexible and quick in disassembly and assembly of the trunk.

[0047] A pulley 701 is provided on the upper surface of the frame connecting plate 7, and the diameter of the middle part of the pulley 701 is smaller than the diameter of the two ends of the pulley; the buckled bottom plate 6 is provided with a first plate position 601 and a second plate position 602, and the first plate position 601 and the second plate position 602 are on different horizontal planes, and the first plate position 601 is in contact with the bottom of the box assembly 2; the buckled bottom plate 6 is also provided with a third plate body 603, and the third plate body 603 is in contact with both sides of the lower end of the box assembly 2. The buckled bottom plate 6 is also provided with a pulley insertion hole 604, which spans the first plate position 601 and the second plate position 602. The pulley insertion hole 604 includes a first hole position 6041 and a second hole position 6042 that are in communication. The inner diameter of the first hole position 6041 is larger than the diameters at both ends of the pulley 701, and the inner diameter of the second hole position 6042 is smaller than the diameters at both ends of the pulley 701 but larger than the diameter of the middle part of the pulley 701; the second hole position 6042 is located at the second plate position 602; when the frame connecting plate 7 is connected to the buckled bottom plate 6, the first hole position 6041 is buckled in from the upper end of the pulley 701, and then the box assembly 2 and the buckled bottom plate 6 are pulled, so that the second hole position 6042 is sleeved with the middle part of the pulley 701; therefore, the second hole position 6042 makes it impossible for the pulley 701 to move up and down and left and right. The trunk can no longer move in the forward and backward directions relative to the motorcycle tail rack, and the first lock body 5 is locked with the first lock buckle 4, so that the trunk can no longer move in the forward and backward directions relative to the motorcycle tail rack. Therefore, the up, down, left, right, front and back directions of the trunk are all fixed, so that the trunk can be firmly fixed on the motorcycle tail rack. The bottom of the second plate position 602 box assembly 2 forms a pulley connection space. After the pulley 701 and the buckled bottom plate 6 are slid together, one end of the pulley 701 is in the pulley connection space. Because of the existence of the pulley connection space, one end of the pulley 701 will not support the bottom of the box body 201, so that the bottom of the box body 201 can fit with the first plate body 601, so that after the buckled bottom plate 6 is connected to the frame connecting plate 7, it will not affect the connection between the buckled bottom plate 6 and the box body 201, thereby ensuring that the trunk can be firmly connected to the motorcycle tail rack.

[0048] A bottom plate contact pad 702 is also provided on the frame connecting plate 7. The bottom plate contact pad 702 and the pulley 701 are located on the same side. When the buckled bottom plate 6 is connected to the frame connecting plate 7, the bottom plate contact pad 702 presses against the side of the second plate position 602 close to the frame connecting plate 7. The bottom plate contact pad 702 is made of rubber material, which increases the friction between the buckled bottom plate 6 and the frame connecting plate 7. When the trunk is loaded with heavy objects, the trunk of the motorcycle may shake up and down during driving. At this time, the bottom plate contact pad 702 can also play a buffering role for the box assembly 2 in the up and down directions.

[0049] The bottom plate contact pad 702 prevents the buckled bottom plate 6 and the frame connecting plate 7 from directly contacting and rubbing against each other, thereby reducing the noise generated by the friction between the buckled bottom plate 6 and the frame connecting plate 7 during riding. In addition, since the bottom plate contact pad 702 props up the buckled bottom plate 6, the pulley 701 only plays a positioning role during this period and does not need to be responsible for propping up the trunk, so that the force applied to the pulley 701 is small, thereby reducing the burden on the pulley 701.

[0050] The first lock body 5 includes a lock body base 501, which is rotatably connected to a locking cover 505, which is rotatably connected to a zipper cover 506, and the zipper cover 506 is provided with a buckle hole 5061; the first lock buckle 4 includes a locking rod 401, and when the first lock body 5 is locked with the first lock buckle 4, the buckle hole 5061 is buckled with the locking rod 401, and when the first lock body 5 is unlocked with the first lock buckle 4, the zipper cover 506 moves obliquely upward toward the first lock buckle 4, and the buckle hole 5061 is away from the locking rod 401. The lock body base 501 is provided with locking plates 5011 on both sides, and the locking plates 5011 are provided with connected sliding lock tracks 50111 and sliding lock grooves 50112.

When the zipper cover 506 is pressed down, the locking cover 505 is also pressed down. When the locking cover 505 is pressed down, the locking tongue 5033 slides into the locking groove 50511 along the sliding rail 50512, and the locking tongue 5033 pulls the locking cover 505 so that the locking cover 505 no longer tilts up, and the zipper cover 506 connected to the locking cover 505 no longer tilts up, and the locking cover 505 and the zipper cover 506 are both parallel to the lock body base 501.

[0051] When unlocking, press the sliding limit plate 5032 toward the lock body base 501, then the spring 504 is pressed down, and the lock tongue 5033 moves in the direction away from the locking hole 5051, and the lock tongue 5033 slides out of the locking groove 50511. At this time, the locking cover 505 is no longer fixed in the up and down directions.
