As shown in fig. 7, an operation window 201f is further opened on the outer side surface of the support pillar 201, and in fig. 6, the operation window 201f is covered by an openable cover plate 201 d. The component mechanism provided in the internal cavity may be a part of an opening/closing mechanism of a vehicle door, for example.

As shown in fig. 8, the door opening and closing mechanism 50 includes an upper transmission mechanism 501, a middle transmission mechanism 503 and a lower transmission mechanism 502, the upper transmission mechanism 501 and the lower transmission mechanism 502 correspond to the top and the bottom of the door respectively, two ends of the upper transmission mechanism 501 and the lower transmission mechanism 502 are connected to two ends of the middle transmission mechanism 503 respectively, the middle transmission mechanism 503 extends from top to bottom, the middle transmission mechanism 503 includes an operating handle 503a located in the middle approximately, and the rotating operating handle 503a can drive the upper transmission mechanism 501 and the lower transmission mechanism 502 to rotate, so as to push the door to move inward and outward.

The middle transmission mechanism 503 may be disposed in an inner cavity of the supporting upright 201, and the operation window 201f corresponds to the position of the operation handle 503a, so as to facilitate the operation of opening the cover plate 201d to rotate the operation handle 503 a. The middle transmission mechanism 503 of the door opening and closing mechanism adjacent to the support portion 20 can be directly installed in the inner cavity of the support portion 20, thereby saving space and protecting the middle transmission mechanism. As shown in fig. 6, the outer side surface of the support top portion 202 of the support portion 20 is provided with a communication port 202a communicating each portion, the upper transmission mechanism 501 can be connected with the middle transmission mechanism 503 through the communication port 202a, and the lower transmission mechanism 502 can be connected with the middle transmission mechanism 503 from the bottom according to the position of the bottom of the middle transmission mechanism 503.

As shown in fig. 6, the door-shaped supporting portion 20 may be an arch structure, and the vertex angles at both ends of the arch structure may not be a standard arc shape, in this embodiment, the supporting top 202 includes the transition section located at both sides of the horizontal section and located at the middle of the horizontal section, the transition section is used for being connected with the supporting upright 201, the transition section is the vertex angle portion of the arch supporting portion 20, the transition section includes two slope sections which are different and are connected in sequence, and the processing is facilitated by such a configuration. The arched support part 20 makes full use of the limit of the vehicle body to improve the loading space in the vehicle, the horizontal section of the support top part 202 of the support part 20 is approximately equal to the width of the roof 10 of the vehicle body, and the transition section is matched with the inner side surface of the upper end of the vehicle door.

The support portion 20 specifically includes a trough-shaped body with the notch facing inward, the trough-shaped body being a metal member, such as a steel structure 201 c. The groove-shaped main body can be of an integrated structure or a split structure, for example, the groove-shaped main body can comprise a whole block of arched side plate, a whole block of arched front end plate and a whole block of arched rear end plate, and then the three are spliced and welded together to form a groove-shaped cross section.

At this time, the support portion 20 further includes a non-metal plate 201e and a metal plate, the metal plate may be a steel plate, the non-metal plate 201e may be made of, for example, a thermoplastic glass fiber reinforced material, the non-metal plate 201e covers the notch portion of the trough-shaped main body located at the arched top corner, and the metal plate covers the rest of the notch portion, thereby forming the support portion 20 of the box-shaped structure. As shown in fig. 6, through test and simulation analysis, the vertex angle position bearing requirement is smaller, the strength requirement can be met by arranging the non-metal plate 201e, and the purpose of reducing weight can be achieved, on the other hand, the non-metal plate 201e and the groove-shaped main body do not need to be welded and fixed, and can be fastened through a fastener, so that the non-metal plate 201e and the groove-shaped main body can be conveniently detached and opened, and the internal mechanism can be overhauled, replaced and the like, for example, the middle transmission mechanism 503 of the vehicle door opening and closing mechanism, wherein the fastener can be a rivet, and certainly can also be other connecting pieces, such as a pin, a bolt and the like. Other positions of the supporting portion 20 require a stronger bearing capacity, so a metal plate is added to improve the local strength. The lower part of the supporting upright 201 belongs to a position with concentrated stress, especially the position connected with the underframe 30, and a thicker metal plate can be sealed to purposely improve the local strength.

With continued reference to fig. 9, fig. 9 is an enlarged view of the portion C in fig. 6.

As shown in fig. 6 and 9, two sets of sealing structures are disposed on the outer side surface of the supporting portion 20, and the two sets of sealing structures are distributed on the front and rear sides of the outer side surface of the supporting portion 20 along the front and rear directions, so as to be in sealing fit with the front side door and the rear side door adjacent to the supporting portion 20, respectively, and ensure the sealing performance when the doors are closed. As shown in fig. 9, the sealing structure specifically includes a sealing strip 201b and a steel structure 201c, the steel structure 201c is a steel edge protruding from the outer surface of the support portion 20, and can be welded on the outer surface of the support portion 20, the sealing strip 201b and the steel structure 201c are from top to bottom, extend from the top of the transition section to the bottom of the support pillar 201, and are matched with the vehicle door from top to bottom, so as to ensure the sealing effect.

In addition, the weather strip 201b and the steel structure 201c are arranged in order in the door opening direction with reference to the door opening direction of the corresponding door, that is, the steel structure 201c is closer to the opening position of the corresponding door. The sealing performance of door can be improved to sealing strip 201b, guarantees the leakproofness when the door is closed, and the steel construction 201c that sets up can play the sealed effect of second way, can prevent that water etc. from keeping on permeating from sealing strip 201b to the inside. The outer side surface area of the support portion 20 is limited, and the steel structure 201c does not occupy too much area, so that the second sealing is possible, and the sealing reliability of the sealing structure of the support portion 20 is enhanced.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
