[0002] The automobile ball head assembly is a key component in various types of automobile parts. The existing automobile ball head assembly usually includes a ball head pin, a ball head seat, a dust cover, an upper ball bowl, a lower ball bowl and a gasket. The ball head pin includes a rod and a ball. The upper ball bowl and the lower ball bowl are both installed in the inner cavity of the ball head seat. The dust cover is connected to the top of the ball head seat, and the gasket is connected to the bottom of the ball head seat.

[0003] The existing ball head assembly places the ball head pin in the ball bowl so that the ball head pin can rotate freely in the ball bowl. During the long-term operation of the ball head pin, the ball head pin or the ball seat will wear out, resulting in a gap between the ball head pin and the ball seat. The existence of the gap causes abnormal noise. The abnormal noise of the ball head assembly will reduce the handling of the car, and the tires are prone to running off the track and eating out. In severe cases, the tires will be severely worn and their service life will be shortened. Grease needs to be applied to the ball head assembly, and the grease needs to be replenished after the ball head assembly is disassembled. Impurities are easily mixed into the ball seat during the replenishment process.

[0004] For example, the automobile ball head assembly with application number 201620453847.X includes a ball seat, a sphere and a pin body connected to the sphere. The ball seat is provided with a flange seat, the flange seat and the pin body are covered with dust covers, a slot is provided at the bottom of the flange seat, and a sealing plate is installed in the slot, which improves the heat dissipation performance, service life and structural strength.

[0005] The above patent has a ball seat installed in the flange seat, and a ball is installed in the ball seat. The ball and the ball seat will wear due to frequent activities, resulting in a gap between the ball and the ball seat. At the same time, the existence of the sealing plate requires the removal of the sealing plate before the ball pin can be replenished with grease, which makes it easy for foreign matter to mix into the ball seat, accelerating the wear of the ball pin and the ball seat.
