Although this patented technology can better connect the ball shell and the ball pin, so that the ball pin can rotate freely in the ball shell, the ball shell still shakes after installation, so that the ball shell and the ball pin cannot be well connected, resulting in the ball pin being stuck when rotating, and friction is prone to occur, resulting in serious wear inside the components, fast replacement time, and short service life. Therefore, those skilled in the art provide a ball shell for an automobile to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a ball shell for a car, aiming to improve the problem in the prior art that the ball shell still shakes after installation, causing the ball pin to get stuck when rotating, and easily causing friction, resulting in serious internal wear of the components, fast replacement time and short service life.

[0007] Through the above technical solution, the ball pin and the ball head can be stably connected for use, thereby preventing the ball bowl and the spring from being damaged by impact or excessive screwing.

[0008] Furthermore, the elastic component includes a spring, which is arranged around the inner wall of the ball bowl cavity, and one end of the spring is fixedly connected to a marble.

[0009] Through the above technical solution, the friction area of ​​the ball head is reduced.

[0010] Furthermore, through holes are provided around the inner wall of the ball bowl cavity, and the other end of the spring is fixedly connected to the inner wall of the through hole.

[0011] Through the above technical solution, the spring is fixed to ensure that the rebound force can be generated.

[0012] Furthermore, the marble is slidably connected inside the through hole.

[0013] Through the above technical solution, the ball head and the marble are against each other, so that the movement of the marble generates a rebound force on the spring compression rebound force, so that the marble is always against the ball head.

[0014] Furthermore, the diameter of the ball bowl cavity is smaller than the diameter of the cover cavity.

[0015] The technical solution can prevent the ball bowl and the spring from being damaged by impact or excessive screwing.

[0016] Furthermore, a step is formed between the ball bowl cavity and the cover cavity.

[0017] The technical solution can prevent the ball bowl and the spring from being damaged by impact or excessive screwing.

[0018] Furthermore, an outer convex ring is fixedly connected to the outer lower side of the spherical shell body.

[0019] Through the above technical solution, the spherical shell is divided into two parts and the strength of the spherical shell is improved.

[0020] Furthermore, the upper diameter of the shrinkage hole is smaller than the diameter of the ball bowl cavity, and the upper diameter of the shrinkage hole is the same as the bottom diameter of the shallow conical hole.

[0021] Through the above technical solution, the ball pin and the ball head can be stably connected and used.

[0022] The utility model has the following beneficial effects:

[0023] In the utility model, by using the coordinated use of structures such as the shallow tapered hole, the shrinkage hole, the ball bowl cavity, the through hole, the spring, the marble, the cover cavity and the like, it is possible to avoid the shaking of the ball shell, which would result in the ball shell and the ball pin being poorly connected and the ball pin being stuck when rotating, thereby increasing the service life of the ball shell and reducing safety hazards.

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.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a ball shell of a car, including a ball shell body 1, a shallow conical hole 3 is arranged on the inner upper side of the ball shell body 1, a shrinkage hole 4 is arranged at the bottom of the shallow conical hole 3, a ball bowl cavity 5 is arranged at the bottom of the shrinkage hole 4, a sealing cavity 6 is arranged at the bottom of the ball bowl cavity 5, and elastic components uniformly distributed are arranged around the inner wall of the ball bowl cavity 5; the elastic component includes a spring 9, the spring 9 is arranged around the inner wall of the ball bowl cavity 5, and one end of the spring 9 is fixedly connected to a marble 7; through holes 8 are opened around the inner wall of the ball bowl cavity 5, and the other end of the spring 9 is fixedly connected to the inner wall of the through hole 8.

[0031] The shallow tapered hole 3, the shrinkage hole 4 and the sealing cavity 6 allow the ball pin and the ball head to be more stably connected for use, and effectively prevent the ball bowl and the spring 9 from being damaged by impact or excessive screwing. The rebound force of the spring 9 causes the marble 7 to offset the ball head, reducing the contact area and reducing the friction.

[0032] Reference Figure 1 , Figure 2 and Figure 3 , the marble 7 is slidably connected to the inside of the through hole 8; the diameter of the ball bowl cavity 5 is smaller than the diameter of the cover cavity 6, and a step is formed between the ball bowl cavity 5 and the cover cavity 6; an outer convex ring 2 is fixedly connected to the outer lower side of the spherical shell body 1, the upper diameter of the shrinkage hole 4 is smaller than the diameter of the ball bowl cavity 5, and the upper diameter of the shrinkage hole 4 is the same as the bottom diameter of the shallow conical hole 3.

[0033] The spring 9 allows the marble 7 to be against the ball head; the diameter of the ball bowl cavity 5 is smaller than the diameter of the cover cavity 6 to form a step, preventing the ball bowl and the spring 9 from being damaged by impact or excessive screwing; the spherical shell body 1 is divided into two parts when passing through the outer convex ring 2, and the strength is improved; the cooperation of the shrinkage hole 4 and the shallow tapered hole 3 makes it convenient for the ball pin and the ball head to be stably connected for use.

[0034] Working principle: through the shallow tapered hole 3 and the shrinkage hole 4, the spring 9 and the marble 7 are arranged in the through hole 8 on the inner wall of the ball bowl cavity 5, so as to ensure a better connection between the ball head and the ball pin in the ball bowl cavity 5 and avoid shaking. The spring 9 and the marble 7 are arranged so that the marble 7 and the ball head are abutted against each other, so that a small part of the ball head is in contact with the marble 7, thereby reducing the friction. A step is formed between the ball bowl cavity 5 and the cover cavity 6, so that the ball bowl and the spring 9 are effectively prevented from being damaged by impact or excessive screwing, thereby avoiding the shaking of the ball shell, resulting in the ball shell and the ball pin not being well connected, causing the ball pin to get stuck when rotating, and prolonging the service life of the ball shell and reducing safety hazards.
