Description

Automobile swing arm structure Technical Field The utility model relates to the technical field of automobile swing arms, in particular to an automobile swing arm structure. Background The swing arm is a connecting mechanism of the frame and wheels, plays a role in guiding and supporting the suspension, can effectively improve the stability of the steering wheel of the automobile, and enables a driver to easily grasp the running direction of the automobile. In the prior art, the swing arm adopts a structure of two bushings, a swing arm body and a ball head, and the ball head is usually connected with the swing arm body in a fixing mode of bolts and nuts, for example, chinese patent publication No. CN219687002U discloses an automobile power-assisted swing arm, wherein the ball head assembly is connected with the swing arm body through the fixing bolts and the fixing nuts, and is fixed through the matching of the bolts and the nuts, vibration generated during long-term running of an automobile is generated, the fixing mode of the fixing bolts and the fixing nuts is easy to loosen, and potential safety hazards are easy to cause. Disclosure of utility model Based on this, the object of the present utility model is to provide an automobile swing arm structure. The utility model provides a technical scheme that an automobile swing arm structure comprises a swing arm mounting plate, a mounting hole formed in the middle of the swing arm mounting plate, and a ball head assembly arranged in the mounting hole; The ball head assembly comprises a ball head seat, a ball head rod movably connected in the ball head seat, a baffle plate arranged on the outer wall of the lower part of the ball head seat, a mounting groove arranged on the outer wall of the upper part of the ball head seat, a clamp spring arranged at the mounting groove, a ball head seat penetrating through the mounting hole and limiting the ball head seat in the mounting hole through the clamp spring and the baffle plate, and a plurality of limiting units detachably connected on the ball head seat, wherein each limiting unit comprises a limiting block and a connecting piece detachably connected with the ball head seat, and the limiting block abuts against the upper surface of the clamp spring. Further, the connecting piece comprises a bolt and a threaded hole formed in the ball seat, the limiting block is arranged on the outer wall of the bolt, and the bolt is screwed into the threaded hole. Further, a limiting ring is arranged on the swing arm mounting plate, and when the clamping spring is in contact with the swing arm mounting plate, the clamping spring is located on the inner side of the limiting ring. Further, the installation hole of swing arm mounting panel department is provided with the arch, the outer wall of bulb seat is provided with the installation department, works as the bulb seat penetrates the installation hole, the installation department outer wall with protruding inner wall interference fit. Furthermore, the top surface of the installation part is inclined from inside to outside to form an inclined surface. Further, notches are formed in two sides of the opening of the ball seat. Further, a dust cover is sleeved between the opening of the ball head seat and the outer wall of the ball head rod. Further, the swing arm mounting plate comprises a lower plate and an upper plate welded with the lower plate, and the mounting holes comprise an upper mounting hole and a lower mounting hole which are respectively formed in the upper plate and the lower plate. The ball head assembly has the beneficial effects that the clamping spring can be prevented from deforming in the axial direction by the limiting block, so that the clamping spring is not easy to separate from the mounting groove, the ball head assembly is not easy to separate from the swing arm mounting plate, and the safety is improved; the ball head assembly is convenient to replace and maintain by means of the limiting ring, radial deformation of the clamping spring can be limited, and therefore the clamping spring is further prevented from being separated from the mounting groove, and accordingly the ball head assembly is separated from the swing arm mounting plate, and safety is improved.
