[0032] See also Figure 1-Figure 3 , a passenger car door structure, comprising:

[0033] A skeleton body 1; and

[0034] A reinforcement frame 2, which is arranged on the surface of the skeleton body 1;

[0035] Based on the above, the reinforcement frame 2 plays a role in strengthening the skeleton body 1 and provides installation space and activity space for the damping mechanism, so that the damping mechanism can work normally.

[0036] like Figure 3 , Figure 7-Figure 8 As shown, the internal parts 3 and the cover plate 4 are arranged inside the reinforcement frame 2 by screws;

[0037] The internal component 3 includes a rectangular component 31, and two opposite sides of the rectangular components 31 are provided with a mounting groove 34, and a permanent magnet tube 5 is arranged inside the mounting groove 34. The opposite sides of the two rectangular components 31 are provided with a hemispherical groove 32, and the inner wall of the hemispherical groove 32 is provided with a semi-annular groove 33;

[0038] The cover plate 4 is a rectangular plate, and the cover plate 4 and the internal component 3 are both set inside the reinforcement frame 2 by screws;

[0039] Based on the above, the setting of the internal part 3, on the one hand, further increases the strength of the reinforcement frame 2, and on the other hand, provides space for the fixation of the permanent magnetic tube 5 and the fixing part 6 and the movement of the metal ball 7, wherein the hemispherical groove 32 and the semi-annular groove 33 play a role in positioning the fixing part 6, and the mounting groove 34 positions the permanent magnetic tube 5, and the cover plate 4 plays a role in preventing the permanent magnetic tube 5 from falling.

[0040] like Figure 4-Figure 6 , Fig. 9 and Fig.10 As shown, the permanent magnetic tube 5 and the fixing member 6 are both provided inside the permanent magnetic tube 5, and the fixing member 6 includes a movable groove 63 and a movable hole 64;

[0041] The fixing member 6 includes a hemispherical block 61, and a movable groove 63 is provided on the opposite side of the two hemispherical blocks 61. The inner diameter of the movable groove 63 is larger than the diameter of the metal ball 7. A positioning ring 62 is provided on the outer surface of the hemispherical block 61. The positioning ring 62 is arranged inside the semi-ring groove 33. The opposite side of the hemispherical block 61 is provided with a movable hole 64, and the movable hole 64 is connected with the movable groove 63.

[0042] Based on the above, the setting of the permanent magnet tube 5 provides a magnetic field. The setting of the fixing part 6, on the one hand, cooperates with the internal part 3 to limit the buffer spring 8 and the top block 9, and on the other hand, allows the metal ball 7 to have space to move. The setting of the positioning ring 62 enables the fixing part 6 to be connected and fixed to the internal part 3 to avoid the movement of the fixing part 6.

[0043] like Figure 4-Figure 6 As shown, the metal ball 7 is disposed inside the movable groove 63;

[0044] The buffer spring 8 and the top block 9 are both arranged inside the movable hole 64, the top block 9 is in contact with the outer surface of the metal ball 7, one end of the top block 9 close to the metal ball 7 is an arc surface, and the buffer spring 8 is arranged between the top block 9 and the internal component 3;

[0045] Based on the function, the metal ball 7, the top block 9 and the buffer spring 8 are all made of non-magnetizable metals (such as aluminum). During the movement of the metal ball 7, on the one hand, it produces damping in the magnetic field to consume energy; on the other hand, after contacting with the top block 9, the buffer spring 8 is compressed for buffering. In the above process, the movement of the metal ball 7 and the top block 9 needs to overcome gravity to do work, thereby further consuming kinetic energy.

[0046] In actual use, by arranging the damping mechanism inside the reinforcement frame 2, the reinforcement frame 2 and the damping mechanism can strengthen the strength of the skeleton body 1, and on the other hand, the damping mechanism moves and does work to buffer and consume the external force.

[0047] When the vehicle door is acted upon by an external force, the external force is transmitted to the reinforcing frame, causing the metal ball 7 to move. During the movement, the metal ball 7 generates damping in the magnetic field to consume energy, and on the other hand, compresses the buffer spring 8 for buffering after contacting the top block 9. In the above process, the movements of the metal ball 7 and the top block 9 need to overcome gravity to do work, thereby further consuming kinetic energy to achieve the effect of weakening the external force acting on the skeleton body 1. Under the premise of not affecting the overall lightweight of the skeleton body 1, the external force can be buffered and consumed, thereby reducing the effect of the external force acting on the vehicle door, and avoiding the situation in which the skeleton body 1 is slightly damaged and the service life is reduced due to external force impact during actual use.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
