[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following is combined with Figures 1-5 This invention describes a car control arm with a quick-change ball joint.

[0026] In one embodiment, a quick-change ball joint automotive control arm includes a control arm body 100 and a docking ring 200 mounted on its outer side, with a ball joint body 300 installed inside the docking ring 200; it also includes a disassembly and assembly mechanism 400, a set of disassembly and assembly mechanisms 400, which are disposed inside the docking ring 200 and used to quickly disassemble and assemble the docking ring 200 and the ball joint body 300; wherein, the disassembly and assembly mechanism 400 includes an arc-shaped retaining strip 410 and an arc-shaped insert 420, the arc-shaped retaining strip 410 is disposed inside the docking ring 200 and engages with the inside of the ball joint body 300, the arc-shaped insert 420 is installed on the outer side of the ball joint body 300, a set of docking blocks 210 is disposed inside the docking ring 200, and one end of the arc-shaped insert 420 passes through and extends to the outer side of the docking block 210.

[0027] like Figure 5 As shown, the disassembly and assembly mechanism 400 also includes a vertical rod 430, which can be inserted into the interior of the ball head body 300, and a rubber ball is installed at the end of the vertical rod 430.

[0028] In this embodiment, when installing the ball head body 300, the ball head body 300 is inserted into the docking ring 200. At this time, the arc-shaped retaining strip 410 is on the outside of the ball head body 300. Then, the user rotates the ball head body 300 so that the arc-shaped insert 420 is inserted into the docking block 210. At the same time, the arc-shaped retaining strip 410 is inserted into the inside of the ball head body 300, completing the horizontal and vertical limiting of the ball head body 300, achieving a quick effect. Then, the vertical rod 430 is inserted into the inside of the ball head body 300, and anti-slip treatment is carried out with a rubber ball to reduce the separation of the vertical rod 430 from the ball head body 300, and the horizontal limiting is performed again to complete the reinforcement treatment.

[0029] When disassembling the ball head body 300, separate the arc-shaped retaining strip 410 from the ball head body 300, then rotate the ball head body 300 in the opposite direction to separate the arc-shaped insert 420 from the mating block 210, and then pull out the ball head body 300.

[0030] It should be noted that the diameter of the rubber ball is larger than the diameter of the vertical rod 430, and the ball head body 300 has an insertion hole inside that matches the vertical rod 430;

[0031] The arc-shaped retaining strip 410, the arc-shaped insert strip 420, and the mating block 210 are all made of steel.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, one side of the arc-shaped card strip 410 is chamfered, and a set of card slots 310 that mate with the arc-shaped card strip 410 are provided on the outer side of the ball head body 300.

[0033] By adopting a chamfered design, during the pressing down of the ball head body 300, the outer edge of the ball head body 300 can abut against the arc surface of the arc-shaped retaining strip 410, causing the arc-shaped retaining strip 410 to move against the contact, eliminating the need for manual driving and improving installation efficiency. When paired with the slot 310 and the arc-shaped retaining strip 410, the connection effect is guaranteed.

[0034] like Figure 5 As shown, a C-shaped rod 411 is provided on the outer side of the arc-shaped clip 410. The middle part of the C-shaped rod 411 is slidably connected to the inside of the docking ring 200. A spring 412 is sleeved on the outer side of the C-shaped rod 411. One end of the spring 412 is installed inside the docking ring 200, and the other end of the spring 412 is fixedly connected to the outer side of the C-shaped rod 411.

[0035] With the spring 412 in place, after the arc-shaped locking strip 410 is abutted, the spring 412 is in a stretched state. Then, when the arc-shaped locking strip 410 is aligned with the slot 310, the deformation force of the spring 412 will push the arc-shaped locking strip 410 to reset, thereby completing the quick docking between the arc-shaped locking strip 410 and the slot 310.

[0036] like Figure 4 and Figure 5 As shown, a support plate is installed at one end of the C-shaped rod 411, and the support plate is slidably sleeved onto the outside of the vertical rod 430.

[0037] The support plate is used to support the vertical rod 430 and limit its movement direction, while the C-shaped rod 411 is also limited to reduce the possibility of accidental movement of the C-shaped rod 411.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, a removable cover plate 220 is provided on the outer side of the docking ring 200.

[0039] A cover plate 220 is used to shield and protect the C-shaped rod 411 and the vertical rod 430, reducing the occurrence of external dust and mud intrusion.

[0040] like Figure 3 and Figure 4 As shown, an annular groove is provided on the outer side of the ball head body 300, and the arc-shaped insert 420 and the docking block 210 are located between the annular groove and the docking ring 200.

[0041] The use of an annular groove provides space for the docking operation of the arc-shaped insert 420 and the docking block 210, ensuring smooth docking of the arc-shaped insert 420 and the docking block 210 without affecting the docking stability between the ball head body 300 and the docking ring 200.

[0042] like Figure 2 As shown, a baffle is provided on the outer side of the ball head body 300, and the baffle contacts the outer side of the docking ring 200.

[0043] During the installation of the ball head body 300, when the ball head body 300 is inserted into the docking ring 200, the baffle plate abuts against the outside of the docking ring 200, indicating that it is in place. This restricts the ball head body 300 from continuing to descend, facilitating the smooth subsequent docking operations of the arc-shaped retaining strip 410 and the arc-shaped insert strip 420.

[0044] Working principle: When installing the ball head body 300, press the ball head body 300 into the docking ring 200 until the baffle contacts the outside of the docking ring 200. At this time, the arc-shaped insert 420 and the docking block 210 are on the same horizontal plane. During this process, the ball head body 300 will move outward against the arc-shaped retaining strip 410. At this time, the arc-shaped retaining strip 410 and the slot 310 are misaligned. Then the user can rotate the ball head body 300 until the sound of the arc-shaped retaining strip 410 entering the slot 310 is heard. At the same time, the arc-shaped insert 420 will complete the docking with the docking block 210. Then the user can push the vertical rod 430 into the ball head body 300.

[0045] When disassembling the ball head body 300, the user can open the cover plate 220 and then pull the vertical rod 430 out along the inside of the ball head body 300. Next, push the C-shaped rod 411 away from the axis of the docking ring 200 to separate the arc-shaped retaining strip 410 from the retaining groove 310. Then, reverse the ball head body 300 to separate the arc-shaped insert 420 from the docking block 210. Finally, pull out the ball head body 300 without the need for external tools.

[0046] The ball head body 300 can be replaced separately to reduce maintenance costs.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
