[0034] The ball socket 100 of the strut assembly of this utility model embodiment is described below with reference to the accompanying drawings.

[0035] Reference Figure 1 , Figure 2 According to an embodiment of the present utility model, a ball joint 100 of a strut assembly is provided, the ball joint 100 having a ball head mounting hole 10 and a shoulder portion 20, the ball head mounting hole 10 being used to mount the ball head 300 of the strut assembly 1000, and the shoulder portion 20 being disposed outside the ball head mounting hole 10.

[0036] The inner wall of the ball head mounting hole 10 is provided with an oil storage and drainage groove 11. The width of the oil storage and drainage groove 11 gradually increases in the direction toward the shoulder 20, so as to guide the lubricating medium to the shoulder 20.

[0037] The ball head piece 300 is matched with the ball socket piece 100, so that the ball head piece 300 has more degrees of freedom, so that the support rod assembly 1000 is applied to a movable device such as an automobile electric tail door, and use is facilitated. For example, one end of the ball head piece 300 is connected to a tail door, and the ball socket piece 100 is installed on a vehicle body. When the tail door is turned to be opened, the ball socket piece 100 is matched with the ball head piece 300, so that the tail door has a certain degree of freedom, and the opening of the tail door is realized.

[0038] The ball head piece 300 is partially located in the ball socket piece 100. The ball socket piece 100 is provided with a ball head mounting hole 10. The ball head piece 300 is in sliding fit with the inner wall of the ball head mounting hole 10, so that the ball head piece 300 is turned. During the turning of the ball head piece 300, part of the ball socket piece 100 hinders the turning of the ball head piece 300. The part of the ball socket piece 100 that hinders the turning of the ball head piece 300 is a shoulder portion 20.

[0039] In the related art, the support rod assembly is widely applied to a structure of an automobile engine cover, a trunk door and household equipment that need to support an opening part. The support rod assembly mainly includes a ball head piece and a ball socket piece. The ball head piece can be inserted into the ball socket piece and relatively turned, so that a multi-angle and flexible support function is realized. In order to reduce the friction resistance between the ball head piece and the ball socket piece, prolong the service life and reduce the movement noise, lubricating oil is usually coated at the contact position of the ball head piece and the ball socket piece.

[0040] However, in actual application, the ball head piece and the ball socket piece are frequently relatively turned or swung. With the increase of use time, the originally coated oil is gradually squeezed out or volatilized, so that the lubricating effect is weakened. Once the lubrication is insufficient, dry friction will occur between the ball head piece and the ball socket piece. Not only the movement resistance of the assembly is increased, but also abnormal sound is easily accompanied, the use experience is affected, and even the part wear is aggravated and the service life of the support rod assembly is shortened.

[0041] Therefore, how to stably maintain the lubricating state between the ball head and the ball socket for a long time without relying on frequent maintenance, and prevent dry friction and abnormal sound caused by oil consumption, has become a key problem that needs to be solved in the current technical field.

[0042] In the embodiment of the utility model, the oil storage drainage groove 11 is arranged on the inner wall of the ball head mounting hole 10, the lubricating medium is stored by using the oil storage drainage groove 11, the lubricating time is prolonged, the dry friction condition is improved, the probability of abnormal sound is reduced under the same working time, the present situation of frequent maintenance is improved, the lubricating state between the ball head piece 300 and the ball socket piece 100 is stably maintained for a long time, and the service life of the support rod assembly 1000 is prolonged.

[0043] It should be noted that in the related art, the shoulder portion collides with the ball head member, dry friction occurs, the ball head member is worn, and corrosion risk exists. In the embodiment of the utility model, the width of the oil storage and drainage groove 11 gradually increases, the lubricating medium is guided to the shoulder portion 20, the lubricating medium on the shoulder portion 20 improves the problem of dry friction, and the corrosion risk is reduced.

[0044] Specifically, the lubricating medium can be grease, lubricating oil or other.

[0045] Specifically, the oil storage and drainage groove 11 is configured as a fan shape. In the initial state when the ball head member 300 and the ball socket member 100 are assembled, the lubricating medium is located in the ball head mounting hole 10. When the ball head member 300 is inserted into the ball head mounting hole 10, the lubricating medium overflows outward from the gap between the ball head member 300 and the ball socket member 100. The fan-shaped oil storage and drainage groove 11 plays a drainage effect and guides part of the lubricating medium to overflow onto the shoulder portion 20.

[0046] According to the ball socket member 100 of the utility model embodiment, the oil storage and drainage groove 11 is arranged on the inner wall of the ball head mounting hole 10.

The oil storage and drainage groove 11 on the inner wall of the ball head mounting hole 10 only occupies part of the area, and stores an appropriate amount of lubricating medium.

[0049] In the related art, the area of the oil storage and drainage groove is greater than 0.4 times the area of the inner wall of the ball head mounting hole, which reduces the strength of the ball socket member. Alternatively, the area of the oil storage and drainage groove is less than 0.2 times the area of the inner wall of the ball head mounting hole, which results in a small amount of lubricating medium stored in the oil storage and drainage groove, a short lubricating state maintenance time between the ball head member and the ball socket member, and abnormal sound.

[0050] In the above scheme, by setting 0.2≤S1 / S2≤0.4, the oil storage and drainage groove 11 occupies an appropriate amount of the inner wall of the ball head mounting hole 10, the storage amount of the lubricating medium is controlled, and the overall strength of the ball socket member 100 is controlled.

[0055] In the related art, the depth of the oil storage drainage groove is greater than 0.22mm, which reduces the strength of the ball and socket part, or the depth of the oil storage drainage groove is less than 0.18mm, which reduces the storage amount of the lubricating medium in the oil storage drainage groove, the lubrication state between the ball part and the socket part is maintained for a short time, and an abnormal sound is generated.

[0056] In the above scheme, by setting the depth of the oil storage drainage groove 11 in the range of 0.18mm to 0.22mm, the size of the oil storage drainage groove 11 is controlled, the storage amount of the lubricating medium is controlled, and the overall strength of the ball and socket part 100 is controlled. While ensuring the overall strength, the storage amount is increased.

The number of the oil storage drainage groove 11 is set in the range of 2 to 4 in the embodiment of the utility model, the problem of the lubrication dead angle is improved while ensuring the strength of the ball and socket part 100, and the overall effect is improved.

[0061] Specifically, the oil storage guide grooves 11 are two, and the two oil storage guide grooves 11 are symmetrically arranged about the central axis of the ball head mounting hole 10; or the oil storage guide grooves 11 are three, and the three oil storage guide grooves 11 are arranged in a ring; or the oil storage guide grooves 11 are four.
