[0033] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] Reference below Figures 1-10 A ball joint device 100 according to an embodiment of the first aspect of the present invention is described.

[0035] like Figures 1-6 As shown, the ball joint connection device 100 according to the first embodiment of the present invention includes: an assembly part 10 , a target part 20 and a ball joint connection part 30 .

[0036] Specifically, the ball connector 30 includes a ball pin 31 and a ball seat 32. The ball pin 31 is a rotating body. One end of the ball pin 31 in the axial direction is connected to the assembly part 10. The other end of the ball pin 31 is provided with a ball head 311. The ball seat 32 is connected to the target part 20. A mounting groove 321 is formed on the ball seat 32. The ball pin 31 is rotatably arranged in the mounting groove 321 around the axis. The ball pin 31 and the inner wall of the mounting groove 321 cooperate with the axial upper limit of the ball pin 31. The assembly part 10 can move relative to the target part 20 in the first direction and the second direction. The first direction (for example Figure 5 ), the left and right direction shown in ), the second direction (e.g. Figure 5 ) and the axial direction of the ball stud 31 (e.g. Figure 5 The up and down directions shown in ) intersect each other.

[0037] The target part 20 is provided on the vehicle body, and the assembly part 10 is a component on the vehicle connected to the vehicle body. For example, the assembly part 10 can be an electrical appliance on the vehicle, an ornament on the vehicle, or other functional components on the vehicle.

[0038] During the vehicle design process, the target part 20 is set at a specified position on the vehicle body according to design requirements, and the orientations of the first direction and the second direction, as well as the axial orientation of the ball stud 31, are adjusted according to the required movement direction of the assembly part 10. In this way, after the assembly part 10 is connected to the target part 20 through the ball stud connector 30, a multi-degree-of-freedom connection of the assembly part 10 on the vehicle can be achieved.

[0039] It is understandable to those skilled in the art that the ball head connection structure is relatively simple. By designing the structure of the ball head connection device 100, the assembly part 10 is connected to the target part 20 with multiple degrees of freedom, and then the target part 20 is connected to the vehicle body. During the vehicle design process, changes to the vehicle body structure can be reduced, thereby reducing the difficulty of vehicle design.

[0040] According to the ball joint connection device 100 of the first embodiment of the present invention, the target part 20 is set at a specified position of the vehicle body, which can realize multi-degree-of-freedom connection of the assembly on the vehicle body, thereby reducing the design difficulty of the vehicle.

[0041] In some embodiments of the present invention, Figure 4 、 Figure 7 、 Figure 8 and Figure 9 As shown, a first limiting groove 3111 is formed on the ball head 311, and the first limiting groove 3111 extends around the axis of the ball head pin 31. A limiting protrusion 322 is formed on the inner wall of the mounting groove 321, and the limiting protrusion 322 extends along the first direction and is engaged in the first limiting groove 3111.

[0042] In this way, when the ball head 311 is displaced from the mounting groove 321, the inner wall of the first limiting groove 3111 can press against the limiting protrusion 322, thereby preventing the ball head 311 from escaping from the mounting groove 321. In this way, the ball head 311 and the inner wall of the mounting groove 321 can be limitedly matched in the axial direction of the ball pin 31.

[0043] During the movement of the ball head 311 in the installation groove 321, the limiting protrusion 322 and the first limiting groove 3111 cooperate to guide and limit the ball head 311, so that the ball head 311 moves along the first direction in the installation groove 321, thereby realizing the constraint of the displacement direction of the assembly part 10 relative to the target part 20 in the first direction.

[0044] In some embodiments of the present invention, Figure 8 and Figure 9 As shown, the outer peripheral wall of the ball head 311 is recessed inwardly to form a first limiting groove 3111. In this way, the structure of the ball head 311 is relatively simple, which can further reduce the design difficulty and production difficulty of the vehicle.

[0045] In some embodiments of the present invention, Figure 2-Figure 7 As shown, the target part 20 includes: a mounting plate 21, a mounting hole 211 is formed on the mounting plate 21 and passes through the mounting plate 21 along the thickness direction, the ball head seat 32 is movably arranged in the mounting hole 211 along the second direction, and the ball head seat 32 and the mounting plate 21 are matched at the axial upper limit position of the ball head pin 31.

[0046] In this way, the assembly part 10 can be moved in the second direction relative to the target part 20, and the structure of the mounting plate 21 is relatively simple. During the vehicle design process, it is less difficult to arrange the mounting plate 21 on the vehicle body, which can further reduce the difficulty of vehicle design.

[0047] In some embodiments of the present invention, Figure 2、 Figure 7 and Figure 10 As shown, a second limiting groove 323 extending along the second direction is formed on at least one side of the ball head seat 32 in the first direction, and the edge of at least one side of the mounting hole 211 in the first direction is formed as a limiting edge 2111, which extends along the second direction and is engaged in the second limiting groove 323.

[0048] That is to say, a second limiting groove 323 may be formed on one side of the ball head seat 32 in the first direction, and one side edge of the mounting hole 211 in the first direction may be formed as a limiting edge 2111; or a second limiting groove 323 may be formed on both sides of the ball head seat 32 in the first direction, and both side edges of the mounting hole 211 in the first direction may be formed as limiting edges 2111.

[0049] In this way, when the ball head seat 32 is displaced from the mounting hole 211, the inner wall of the second limiting groove 323 can press against the limiting edge 2111, thereby preventing the ball head seat 32 from escaping from the mounting hole 211, thereby realizing the axial limiting cooperation between the ball head seat 32 and the mounting plate 21 on the ball head pin 31.

[0050] When the ball head seat 32 moves in the mounting hole 211, the second limiting groove 323 and the limiting edge 2111 cooperate to limit and guide the ball head seat 32, so that the ball head seat 32 moves along the second direction, thereby realizing the constraint of the displacement direction of the assembly part 10 relative to the target part 20 in the second direction.

[0051] In some embodiments of the present invention, Figure 2 、 Figure 7 、 Figure 8 and Figure 10 As shown, the ball head seat 32 is provided with a limiting flange 324 and a limiting protrusion 325 on at least one side in the first direction. The limiting flange 324 and the limiting protrusion 325 are arranged at intervals in the axial direction of the ball head pin 31. The limiting flange 324 and the limiting protrusion 325 cooperate to define a second limiting groove 323.

[0052] That is, the ball head seat 32 may be provided with a limiting flange 324 and a limiting protrusion 325 on one side in the first direction, or the ball head seat 32 may be provided with a limiting flange 324 and a limiting protrusion 325 on both sides in the first direction.

[0053] Therefore, during the vehicle design process, by adjusting the size, shape or spacing parameters of the limiting flange 324 and the limiting protrusion 325, the ball head seat 32 can be adapted to more models of target parts 20, which can further reduce the difficulty of vehicle design.

[0054] In some embodiments of the present invention, Figure 2、 Figure 8 and Figure 10 As shown, the limiting protrusion 325 is provided on the side of the mounting plate 21 away from the assembly part 10 . In the direction of the assembly part 10 toward the target part 20 , the side surface of the limiting protrusion 325 away from the mounting plate 21 extends obliquely toward the axis direction of the ball stud 31 .

[0055] During the assembly process, when the ball head 311 is inserted into the mounting groove 321, the side surface of the limiting protrusion 325 away from the mounting plate 21 first contacts the limiting protrusion 322 of the mounting groove 321. As the ball head 311 gradually extends in, the degree of contact between the side surface of the limiting protrusion 325 away from the mounting plate 21 and the limiting protrusion 322 gradually increases. When the limiting protrusion 322 enters the first limiting groove 3111, the ball head 311 is assembled on the ball head seat 32.

[0056] The contact degree between the limiting protrusion 322 and the surface of the limiting block 325 away from the mounting plate 21 gradually increases, which can reduce the difficulty of installing the ball head 311 into the mounting groove 321 .

[0057] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the limiting flange 324 is connected to the edge of the mounting groove 321 and is arranged around the mounting groove 321. This, on the one hand, can increase the contact area between the limiting flange 324 and the mounting plate 21, improving the stability and reliability of the ball seat 32 on the mounting plate 21. On the other hand, it can reduce the space occupied by the ball seat 32 on the mounting side of the ball stud 31. During the vehicle design process, the mounting side of the assembly part 10 can have more space, thereby further reducing the design difficulty of the vehicle.

[0058] In some embodiments of the present invention, Figure 5-Figure 7 As shown, a limiting rib 22 is further provided on the mounting plate 21, and the limiting rib 22 extends along the second direction. The limiting flange 324 is arranged side by side with the limiting rib 22, and the side edge of the limiting flange 324 close to the limiting rib 22 extends along the second direction.

[0059] Therefore, on the one hand, the limiting rib 22 can guide and limit the limiting flange 324 in the second direction, thereby further constraining the displacement direction of the assembly part 10 relative to the target part 20 in the second direction. On the other hand, when the ball pin 31 drives the ball head seat 32 to rotate, the limiting rib 22 can resist the limiting flange 324, thereby preventing the ball head seat 32 from rotating in the mounting hole 211, thereby improving the stability of the assembly part 10 installed on the target part 20.

[0060] Preferably, the limiting flange 324 is arranged around the installation groove 321 , and there are two limiting ribs 22 , which are respectively arranged on both sides of the ball head seat 32 in the second direction.

[0061] In some embodiments of the present invention, the ball pin 31 is threadedly connected or die-cast to the assembly part 10, and a positioning flange 312 is provided on the outer peripheral wall of the ball pin 31. The positioning flange 312 is provided between the ball head 311 and the assembly part 10. The positioning flange 312 can position the assembly part 10 on the ball pin 31 and prevent the assembly part 10 from being over-assembled.
