[0073] The elastic member 53 can be made of rubber, plastic, or the like. In this application, the elastic member 53 is taken as an example made of rubber. The first skeleton 51 and the second skeleton 52 can each be formed by injection molding of PA66 (polyamide resin, nylon) material. The second skeleton 52 can be a standard general-purpose part to reduce the manufacturing cost of the ball pin protection device 100. The first skeleton 51, the elastic member 53, and the second skeleton 52 can be bonded together by a rubber vulcanization process. The elastic member 53 is wrapped around the first skeleton 51 and the second skeleton 52. The first skeleton 51 and the second skeleton 52 can each be provided with a flow hole 54 to increase the flow performance of the rubber during the rubber vulcanization process of the first skeleton 51, the elastic member 53, and the second skeleton 52, thereby avoiding the generation of bubbles during the vulcanization process and improving the bonding strength between the first skeleton 51, the elastic member 53, and the second skeleton 52, and further improving the stability and reliability of the first device body 20 and the second device body 30.
[0074] Further, in the first device body 20, the first skeleton 51 can be arranged at the first notch 211 of the first end wall 21, and the first skeleton 51 is adapted in shape and size to the first notch 211. The second skeleton 52 can be arranged at the third notch 231 of the second end wall 23, and the second skeleton 52 is adapted in shape and size to the third notch 231. The positioning boss 41 of the first skeleton 51 and the inner wall of the first notch 211 can each be formed on the first skeleton 51. The two second clamping bosses 42 of the second end wall 23 can each be formed on the second skeleton 52. The top end of the arc-shaped section corresponding to the positioning boss 41 of the first skeleton 51 can be formed with an arc-shaped groove 511 to reduce the opening stiffness of the first skeleton 51, thereby facilitating the installation of the first end wall 21 and further reducing the installation complexity of the ball pin protection device 100.
[0075] In the second device body 30, the first skeleton 51 can be arranged at the second notch 311 of the third end wall 31, the first skeleton 51 is matched with the size and shape of the second notch 311, the second skeleton 52 can be arranged at the fourth notch 331 of the fourth end wall 33, the second skeleton 52 is matched with the size and shape of the fourth notch 331, wherein the first clamping boss 40 of the third end wall 31 and the positioning boss 41 of the inner wall of the second notch 311 can be formed on the first skeleton 51, the two second clamping bosses 42 of the fourth end wall 33 can be formed on the second skeleton 52, and the third end wall 31 can be formed with an avoiding groove 55 for avoiding the stable rod connecting rod 209 of the ball pin 200, and the avoiding groove 55 is communicated with the second notch 311.
[0076] The first skeleton 51 and the second skeleton 52 can be made of PA66 material, which has high strength and rigidity, so that the strength and rigidity of the first clamping boss 40, the second clamping boss 42 and the positioning boss 41 can be improved, and the rigidity of the matching area between the ball pin protection device 100 and the ball pin 200 can be improved, and the firmness of the connection can be improved.
[0077] Further, the elastic member 53 can be formed with a deformation guide structure 50 extending along the circumference of the elastic member 53, which can be configured as a groove or a protrusion. When the ball pin 200 performs a swing movement, it will produce extrusion or stretching to the ball pin protection device 100. When the ball pin 200 swings and extrudes the ball pin protection device 100, the groove of the deformation guide structure 50 can be deformed. When the pin swings and stretches the ball pin protection device 100, the protrusion of the deformation guide structure 50 can be deformed, so that the ball pin protection device 100 can adapt to the swing movement of the ball pin 200, which helps to reduce friction and wear caused by mismatched movement, thereby improving the operation efficiency of the ball pin 200, and the deformation guide structure 50 can also be plastically deformed when the ball pin protection device 100 is installed, facilitating the installation of the ball pin protection device 100.
