[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a firmly connected automobile swing arm, comprising a swing arm 1, a connecting rod 9 is fixedly connected to the right side of the swing arm 1, a fixing plate 8 is fixedly connected to the upper and lower ends of the connecting rod 9, a bolt 6 is threadedly connected to the top of the fixing plate 8, a movable plate 7 is rotatably connected to the end of the bolt 6, a cone head 12 is fixedly connected to the front and rear sides of the bottom of the movable plate 7, a limiting mechanism 2 is installed on the left side of the swing arm 1; a connecting clamp 4 is installed on the right side of the outer wall of the swing arm 1; a through hole 5 is opened on the left side of the connecting clamp 4, and a groove 13 is opened on the front and rear ends of the right side of the outer wall of the swing arm 1; a balloon 14 is installed on the inner side of the groove 13; a slider 11 is fixedly connected to the left side of the movable plate 7, a slide groove 10 is opened on the right side of the connecting rod 9, and the slider 11 is slidably connected to the slide groove 10; an opening 3 is opened on the outer wall of the swing arm 1;

[0038] Specifically, insert the right side of the swing arm 1 into the connecting clip 4 on the component; this is the first step to ensure that the swing arm 1 is stably connected to the component; next, align the through hole 5 with the slot 13, which is the second step to prepare for the subsequent limiting work; the precise alignment of the through hole 5 and the slot 13 helps to ensure the stability of the connection; the third step is to rotate the two bolts 6 to drive the movable plate 7 to descend; during the descent of the movable plate 7, the slider 11 will slide in the slide groove 10; the key to this step is that the descent of the movable plate 7 must drive the sliding of the slider 11 to achieve the limiting work when the movable plate 7 moves; while the limiting work is in progress, the moving trajectory of the movable plate 7 is also carefully planned; the fourth step is to descend the movable plate 7, and the cone head 12 is synchronously descended; in this way, the cone head 12 can pass through the through hole 5 and the slot 1 in turn. 3; In the fifth step, when the cone head 12 is inserted into the slot 13, the balloon 14 will be punctured; at the moment when the balloon 14 ruptures, the high-strength adhesive leaks out of the balloon 14; finally, the high-strength adhesive adheres and fixes the movable plate 7, the connecting clip 4 and the swing arm 1; through the clamping force and bonding force of the movable plate 7, the connection stability of the swing arm 1 and the external parts is enhanced in many aspects; this connection method avoids the loosening that may occur when fixing with screws, thereby improving the reliability of the entire connection system; this design achieves a stable connection between the swing arm 1 and the external parts through precise component alignment, reasonable limit work, carefully planned movement trajectory and the use of high-strength adhesive; this connection method not only simplifies the installation process, but also improves the reliability of the connection and avoids the loosening problem that may occur when fixing with screws.

[0039] Reference Figure 1 and Figure 3The limiting mechanism 2 includes a connecting shaft 202, which is rotatably connected to the left end of the swing arm 1, and the upper and lower ends of the left side of the swing arm 1 are fixedly connected to the inclined plate 201, the left side of the inclined plate 201 is fixedly connected to a spring 205, the left end of the spring 205 is fixedly connected to a force plate 203, and the middle part of the left side of the inclined plate 201 is fixedly connected to a blocking column 204;

[0040] Specifically, when the component flips excessively, the first thing it encounters is the force plate 203; the function of the force plate 203 is to prevent the component from continuing to flip and causing damage during the flipping process; when the external component collides with the force plate 203, the spring 205 will also play a role, driving the force plate 203 to retract; this design allows the impact force on the component to be reduced and the risk of damage to be reduced through the buffering effect of the spring 205 during the flipping process of the component; however, if the component continues to flip after the collision, the blocking column 204 will play a role; the blocking column 204 is located on both sides of the force plate 203, and when the component flips to a certain extent, the blocking column 204 will contact the component to block and limit it; in this way, the excessive flipping of the component can be effectively prevented, and the risk of component damage caused by excessive torque is further reduced; through this design, when the mechanical equipment encounters the situation of excessive flipping of the component, measures can be taken in time to limit it, thereby ensuring the safe operation of the equipment; in actual application, this design not only improves the stability and reliability of the equipment, but also greatly reduces the maintenance cost caused by component damage.

[0041] Reference Figure 2 , the two movable plates 7 are symmetrically designed;

[0042] Specifically, the symmetrically designed movable plate 7 increases the accuracy of fixation.

[0043] Working principle: When the automobile swing arm is connected to other parts, the right side of the swing arm 1 is inserted into the connecting clip 4 on the parts, and the through hole 5 is aligned with the slot 13. The two bolts 6 are rotated to drive the movable plate 7 to descend. During the descent of the movable plate 7, the slider 11 is driven to slide in the slide groove 10, which is used for the limit work when the movable plate 7 moves. At the same time, the moving trajectory of the movable plate 7 is planned. The cone head 12 is synchronously lowered by the descent of the movable plate 7, so that the cone head 12 passes through the through hole 5 and the slot 13 in turn, and the cone head 12 is inserted into the slot 13 to puncture the balloon 14. When the balloon 14 is broken, the high-strength adhesive leaks out of the balloon 14, The movable plate 7, the connecting clip 4 and the swing arm 1 are glued and fixed. The clamping force and the adhesive force of the movable plate 7 increase the stability of the swing arm 1 when connected to the external components in many aspects, avoid loosening when fixed with screws, and meet the needs of use. After the connecting shaft 202 of the swing arm 1 is connected to the components, if the components are overturned, the external components will collide with the force plate 203, and the spring 205 will drive the force plate 203 to retract. If it continues to flip, the force plate 203 will be blocked and limited by the blocking column 204, which reduces the risk of component damage caused by excessive torque and brings convenience to use.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
