The designed support strength is limited and cannot be increased once determined. When loaded between components exceeding the limit, breakage is likely to occur, thus exhibiting certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a high-life automotive suspension arm to solve the problem that the support strength of the existing suspension arm design is limited and cannot be increased once determined.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-life automotive suspension arm includes a swing arm body. A stabilizing ball joint and a vertical bushing are sequentially mounted at the top two ends of the swing arm body. A horizontal bushing is mounted at the bottom end of the swing arm body. A ball joint mounting plate is provided between the stabilizing ball joint and the swing arm body to support the stabilizing ball joint. The vertical bushing has a first mounting hole, and the horizontal bushing has a second mounting hole. Grooves are formed on both bent sides of the swing arm body. Adjustment components are provided in both grooves, and a reinforcing metal liner for strengthening the swing arm body is provided between the two adjustment components.

[0007] Preferably, the adjusting component includes a rotating column, which is rotatably installed in its corresponding groove. A through-plate slit is provided through the rotating column for the insertion of a reinforcing metal liner. Multiple locking blocks are evenly installed on the end face of the rotating column. Locking components that match the multiple locking blocks on the rotating column are installed on the main body of the swing arm.

[0008] Preferably, the locking component includes a support frame fixed to the main body of the swing arm, a vertical column inserted into and slidably connected to the support frame, a pressure plate fixedly installed at one end of the vertical column near the rotating column, and a chuck installed at one end of the pressure plate near the rotating column.

[0009] Preferably, a sleeve frame is fixedly sleeved at the end of the vertical column away from the pressure plate, and a metal cable can be connected to the end of the vertical column away from the pressure plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 As shown, this utility model provides a high-life automotive suspension arm, including a swing arm body 1. A stabilizing ball head 4 and a vertical bushing 2 are sequentially installed at the top two ends of the swing arm body 1. A horizontal bushing 3 is installed at the bottom end of the swing arm body 1. A ball head mounting plate 41 is provided between the stabilizing ball head 4 and the swing arm body 1 to support the stabilizing ball head 4. The vertical bushing 2 has a first mounting hole 21, and the horizontal bushing 3 has a second mounting hole 31. Grooves 11 are provided on both bent sides of the swing arm body 1, and adjusting components 6 are provided in both grooves 11. A reinforcing metal liner 5 for strengthening the swing arm body 1 is provided between the two adjusting components 6. By providing two grooves 11 for installing the two adjusting components 6 on the two bent sides of the swing arm body 1, and by adding a reinforcing metal liner 5 between the two adjusting components 6 to provide reinforcement and support, the compressive strength of the swing arm body 1 can be improved. This can minimize the risk of breakage of the swing arm body 1 when it is loaded with components exceeding its design limits.

[0025] Specifically, the adjustment component 6 includes a rotating column 61, which is rotatably installed in its corresponding groove 11. A through-slit 611 is provided through the rotating column 61, with a thickness of 5-10 mm, to facilitate the insertion and installation of the reinforcing metal liner 5. The reinforcing metal liner 5 can be made of stainless steel. The through-slit 611 allows the reinforcing metal liner 5 to be inserted. Multiple locking blocks 613 are evenly installed on the end face of the rotating column 61. Locking and limiting parts 63 that match the multiple locking blocks 613 on the rotating column 61 are installed on the swing arm body 1. The bending degree of the reinforcing metal liner 5 between the two adjustment components 6 is adjustable, which can adapt to the addition and installation of reinforcing metal liners 5 on various swing arm bodies 1. The practicality and adaptability of the reinforcing metal liner 5 and the adjustment component 6 are greatly improved, making it suitable for assembly on various swing arm bodies 1.

[0026] In a further embodiment, refer to Figure 3 and Figure 4 As shown, the locking member 63 includes a support frame 631 fixed on the swing arm body 1. A vertical column 632 is inserted into and slidably connected to the support frame 631. A pressure plate 635 is fixedly installed at one end of the vertical column 632 near the rotating column 61. A chuck 636 is installed at one end of the pressure plate 635 near the rotating column 61. A sleeve frame 633 is fixedly sleeved at the end of the vertical column 632 away from the pressure plate 635. A metal cable can be connected to the end of the vertical column 632 away from the pressure plate 635. The metal cable facilitates the lifting of the vertical column 632, the pressure plate 635, and the chuck 636. A compression spring 634 is sleeved on the vertical column 632. One end of the compression spring 634 is fixedly connected to the side wall of the support frame 631, and the other end of the compression spring 634 is fixedly connected to the end face of the pressure plate 635.

[0027] The chuck 636 has multiple slots evenly distributed around one end of the rotating column 61, which are matched one-to-one with the slot blocks 613. This allows the rotating column 61 to be locked again by lowering the chuck 636 after it has rotated.

[0028] In this embodiment, when the rotating column 61 is engaged with the locking member 63, the rotating column 61 is locked. Only when the pressure plate 635 and the chuck 636 are lifted, and the locking block 613 at the end of the rotating column 61 is no longer restricted, can the rotating column 61 be rotated in the groove 11. The two rotating columns 61 can rotate after being unlocked at the same time, which makes it convenient for the reinforcing metal liner 5 to be bent to a suitable curvature, and to cooperate with the swing arm body 1 for auxiliary support. The curvature of the reinforcing metal liner 5 after bending is flexible and adjustable, which is highly practical and can adapt to the addition and installation of reinforcing metal liner 5 on various swing arm bodies 1. It is suitable for assembly on various swing arm bodies 1.

[0029] In a further embodiment, refer to Figure 4As shown, the side of the rotating column 61 is provided with a threaded hole 612 that communicates with the through-plate slit 611, and a fastening bolt 62 is detachably threadedly connected in the threaded hole 612.

[0030] In this embodiment, after the reinforcing metal liner 5 is initially positioned by passing through the two through-slits 611 of the two rotating columns 61, the two locking members 63 are pulled up. At this time, the two rotating columns 61 can move and press against the middle of the reinforcing metal liner 5 to cause the reinforcing metal liner 5 to deform to a suitable degree of curvature. Then, the two locking members 63 are lowered to lock the two rotating columns 61. After that, the two fastening bolts 62 are tightened. Thus, the reinforcing metal liner 5 after bending is completely positioned, and the reinforcing metal liner 5 can be fully engaged in supporting the swing arm body 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
