[0003] Currently, there are three main installation methods for the plastic insert of the aluminium alloy automobile wheel: the first method is to install the plastic insert by self-tapping screw structure. The biggest disadvantage of this method is that the plastic insert can only be disassembled and installed from the back of the aluminium alloy wheel after the wheel is removed from the vehicle. After disassembly by self-tapping screw, the fastening torque will be attenuated, and the plastic insert will be scrapped due to the risk of thread slipping during repeated disassembly. The second method is to install the plastic insert by embedding copper sleeve structure. The biggest disadvantage of this method is that the plastic insert can only be disassembled and installed from the back of the aluminium alloy wheel after the wheel is removed from the vehicle. The bolt and the embedded copper sleeve need to be completely aligned to be screwed in, which takes a long time to install. The third method is to install the plastic insert by buckle structure. The biggest disadvantage of this method is that the insert needs to be pried from the edge by external force during disassembly, which can easily damage the insert during the disassembly process. Moreover, the part in contact between the buckle and the aluminium alloy wheel is prone to wear, and gaps may occur between the insert and the aluminium alloy wheel after long-term use, resulting in abnormal noise or even falling off.

[0027] As shown in Figures 1-3 A wheel insert connecting mechanism is provided with a mounting cylinder 1, an insert stop 11 is arranged on the outer side of the end of the mounting cylinder 1, a middle rod 2 is movably arranged inside the mounting cylinder 1, a resilient reset member 3 is arranged between the mounting cylinder 1 and the middle rod 2, a limiting ring 21 is arranged at the bottom of the middle rod 2, a locking hole 12 is arranged on the mounting cylinder 1, a locking ball 13 is arranged in the locking hole 12, and a movable slot 22 is arranged on the middle rod 2, which is arranged one-to-one corresponding to the locking hole 12.

[0028] Specifically, the mounting cylinder 1 is in the form of an open-topped tubular structure, the middle rod 2 is movably arranged inside the mounting cylinder 1, the limiting ring 21 is arranged at the bottom of the middle rod 2 to limit the movement range of the middle rod 2, and the insert stop 11 is arranged on the outer side of the end of the mounting cylinder 1 to block the wheel insert 100 during installation and prevent it from falling. In use, the mounting cylinder 1 is inserted through the reserved hole or mounting position on the wheel insert 100, the insert stop 11 is tightly attached to one side of the wheel insert 100, serving as positioning and supporting, and the connecting mechanism is fixed to the wheel 200 together with the wheel insert 100. When it is necessary to lock the connecting mechanism to the aluminum alloy wheel 200, the middle rod 2 is first pushed by an external force, and the middle rod 2 moves in the axial direction of the mounting cylinder 1 under the action of the external force. With the movement of the middle rod 2, the locking hole 12 overlaps the movable slot 22, the locking ball 13 is located in the movable slot 22, and at the same time, the mounting cylinder 1 is installed in the mounting hole of the wheel 200. As shown in Figure 2As shown, at this time, the middle rod 2 is stopped from being pushed, and under the elastic force of the elastic reset member 3, the middle rod 2 returns to the initial position, the locking hole 12 is misaligned with the movable slot 22, and the locking ball 13 is extruded by the middle rod 2 and further enters the locking hole 12. Since the locking ball 13 is subjected to a certain pressure, it is tightly clamped at the opening of the locking hole 12 and partially protrudes to the outside of the mounting cylinder 1, and the locking ball 13 remains in the protruding state, so that the connecting mechanism can be firmly locked on the aluminum alloy wheel 200 and prevented from falling off or moving. When it is necessary to unlock and disassemble the connecting mechanism, the middle rod 2 is pushed again, and with the movement of the middle rod 2, the positional relationship between the locking hole 12 and the movable slot 22 changes again. As shown, Figure 3 When they are aligned, the locking ball 13 comes out of the locking hole 12 and falls into the movable slot 22, and the connecting mechanism is in an unlocked state. At this time, the connecting mechanism can be easily disassembled from the wheel 200. By arranging the locking hole 12, the locking ball 13, and the movable slot 22 on the middle rod 2, a simple locking and unlocking mechanism is realized. That is, when the locking ball 13 is extruded by the middle rod 2 and protrudes to the outside of the mounting cylinder 1, the connecting mechanism can be firmly locked on the aluminum alloy wheel, and when it is necessary to unlock, the movable slot 22 is aligned with the locking hole 12 by pressing the middle rod 2, and the locking ball 13 can easily enter the movable slot 22 to achieve unlocking. By arranging the elastic reset member 3, a stable reset force is provided, so that when the connecting mechanism is inserted into the wheel 200, it always remains in a locked state, which helps to improve the reliability of the connecting mechanism. By simply pressing the middle rod 2, the locking and unlocking can be converted, so that the user can easily use the connecting mechanism without the need for complex tools or steps, and the operation is simple and convenient for installation and disassembly.

When the pressing block 23 contacts the pressing block stop 16, the movable slot 22 is aligned with the locking slot 11.

[0032] Specifically, the additional pressing block 23 enables the user to more intuitively feel the moving position of the middle rod 2 when operating the connecting mechanism. When the pressing block 23 contacts the pressing block stop 16, the user can confirm through touch that the middle rod 2 has moved to a specific position. When the pressing block 23 contacts the pressing block stop 16, the movable slot 22 is automatically aligned with the locking hole 12, making the locking and unlocking process simpler and more intuitive.

[0033] As shown in Figure 1 , 2 , a snap spring slot 14 is provided on the outer wall of the mounting cylinder 1, and a snap spring 15 is arranged in the snap spring slot 14.
