[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the vehicle itself, where the head of the vehicle represents "front", the tail of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down", the "inside" side refers to the side facing inside the cab, and the "outside" side refers to the side facing outside the cab.

[0046] In addition, the front and rear directions of the vehicle body defined in the embodiments of the present invention refer to the front and rear directions of the forward direction of the vehicle during driving, the left and right directions of the vehicle body defined refer to the left and right directions of the forward direction of the vehicle during driving, and the up and down directions of the vehicle body defined refer to the up and down directions of the forward direction of the vehicle during driving.

[0047] Please also refer to Figure 1 and Figure 2The vehicle sliding door system provided by the present invention will now be described. The vehicle sliding door system comprises a door inner panel 1, a vehicle body pillar 2, a door guard 3, a central hinge structure 4, and a shielding member 5. The vehicle body pillar 2 is located behind the door inner panel 1; the door guard 3 is fixedly connected to the inner side of the door inner panel 1; a first avoidance area 311 is provided on the door guard 3, and a first avoidance hole 312 is formed in the first avoidance area 311; the central hinge structure 4 is located on the inner side of the first avoidance area 311; one end of the central hinge structure 4 passes through the first avoidance hole 312 and is connected to the door inner panel 1; the other end of the central hinge structure 4 is connected to the vehicle body pillar 2; the shielding member 5 is located at the first avoidance hole 312; one end of the shielding member 5 is hinged to the door guard 3, and the other end of the shielding member 5 abuts against the central hinge structure 4.

[0048] The door inner panel 1 is located on the inner side of the door outer panel 6, and a door handle 7 is fixed on the door inner panel 1. A third avoidance hole 316 is provided on the door guard plate 3, and the door handle 7 is embedded in the third avoidance hole 316; in addition to the middle hinge structure 4, the above-mentioned sliding door system also includes a lower hinge structure 8.

[0049] Specifically, a second avoidance area is provided on the door guard plate 3, and a fourth avoidance hole is provided on the second avoidance area. The lower hinge structure 8 is located on the inner side of the second avoidance area. One end of the lower hinge structure 8 passes through the fourth avoidance hole and is fixedly connected to the door inner panel 1. The other end of the lower hinge structure 8 is fixed on the vehicle body pillar 2.

[0050] When the vehicle sliding door system needs to be opened, the middle hinge structure 4 and the lower hinge structure 8 are started at the same time, the middle hinge structure 4 swings around its other end toward the outside of the vehicle body, and the lower hinge structure 8 also swings around its other end toward the outside of the vehicle body, thereby driving the entire door to slide backward and open.

[0051] It should be noted that the first avoidance hole 312 not only avoids one end of the middle hinge structure 4 , but also cannot interfere with the movement of the middle hinge structure 4 .

[0052] When the vehicle door slides backward, the other end of the shielding member 5 is always in contact with the middle hinge structure 4, and moves along with the middle hinge structure 4, so that the shielding member 5 swings around its rotating end. The shielding member 5 cooperates with the middle hinge structure 4 to always cover the first avoidance hole 312.

[0053] Compared with the prior art, the vehicle sliding door system provided by the present invention has a first avoidance area 311 and a first avoidance hole 312 set on the door guard plate 3, which are used to avoid the middle hinge structure 4 and does not hinder the movement of the middle hinge structure 4; in addition, a covering member 5 is provided on the inner side of the first avoidance hole 312. When the middle hinge structure 4 moves, the covering member 5 cooperates with the middle hinge structure 4 to always cover the first avoidance hole 312 and prevent the first avoidance hole 312 from leaking out, thereby not affecting the appearance performance of the door guard plate 3 and enhancing the overall exquisiteness of the door.

[0054] It should be noted that the vehicle sliding door system generally opens from front to back when opened. Based on the opening direction of the vehicle sliding door system, the front end of the central hinge structure 4 passes through the first avoidance hole 312 and connects to the door inner panel 1; the rear end of the central hinge structure 4 connects to the vehicle body pillar 2; the front end of the shielding member 5 is hinged to the door guard plate 3, and the rear end of the shielding member 5 abuts the central hinge structure 4. Therefore, in this embodiment, "one end" refers to the "front end," and the "other end" refers to the "rear end."

[0055] In some embodiments, the shielding member 5 and the door guard plate 3 may be connected by the following Figure 3 and Figure 4 The structure shown, see Figure 3 and Figure 4 The front end of the shielding member 5 is fixed to the door guard plate 3 through a rotating shaft structure 51 , and a torsion reset member 52 is provided on the rotating shaft structure 51 .

[0056] When the vehicle door is opened and the middle hinge structure 4 swings around its rear end toward the outside of the vehicle body, the middle hinge structure 4 will push the shielding member 5 to swing. Since a torsional reset member 52 is provided at the front end of the shielding member 5, the torsional reset member 52 will apply a reverse force to the shielding member 5 so that the rear end of the shielding member 5 is always in contact with the outer surface of the middle hinge structure 4. The shielding member 5 cooperates with the middle hinge structure 4 to always cover the first avoidance hole 312.

[0057] Specifically, the shielding member 5 is a single-plate structure with a first mounting block at its front end. The door guard 3 is provided with second mounting blocks above and below the first mounting block. A pivot structure 51 extends through the two second mounting blocks and the first mounting block. A torsional return member 52 is sleeved on the pivot structure 51, with its ends fixedly connected to the shielding member 5 and the door guard 3, respectively.

[0058] The torsion reset member 52 is a torsion spring or a hinge. The present embodiment does not limit the specific structure of the torsion reset member 52 , as long as the torsion reset member 52 can drive the shielding member 5 to swing back to its original position.

[0059] In some embodiments, the door guard plate 3 may be Figure 3 and Figure 4 The structure shown, see Figure 3 and Figure 4 The door guard panel 3 includes a guard panel body 31 and a decorative panel 32. The guard panel body 31 is provided with a first avoidance area 311; the guard panel body 31 is also provided with a storage area 313; the decorative panel 32 is connected to the inner side of the storage area 313, and together with the storage area 313, it forms a map pocket; the front portion of the decorative panel 32 has an upwardly extending upper connecting portion 321, which is located in front of the first avoidance hole 312. The front end of the shielding member 5 is hinged to the upper connecting portion 321 via a rotating shaft structure 51.

[0060] In addition to the first avoidance area 311, the guard plate body 31 also has a third avoidance hole 316 for avoiding the door handle 7, and a second avoidance area for avoiding the lower hinge structure 8; in the upper and lower directions of the vehicle body, the storage area 313 is located between the first avoidance area 311 and the second avoidance area.

[0061] A map pocket is formed between the storage area 313 on the guard plate body 31 and the decorative plate 32 to store items, thereby improving the convenience of using the car door.

[0062] In addition, the shielding member 5 is fixed with the aid of the decorative panel 32. On the one hand, while satisfying the need for the shielding member 5 to be located inside the first avoidance area 311, the structure of the shielding member 5 can be simplified so that the shielding member 5 can be a simple plate-like structure; on the other hand, since the decorative panel 32 is smaller than the guard plate body 31, it is easier to form a connection structure with the shielding member 5 (i.e., the upper connection portion 321) on the decorative panel 32.

[0063] Specifically, the storage area 313 has an outer concave portion that is recessed toward the outside of the vehicle body and an inner convex portion formed on the front edge, lower edge and rear edge of the outer concave portion; the four edges of the decorative panel 32 are fixedly connected to the inner convex portion, and a map pocket is formed between the decorative panel 32 and the outer concave portion to place items.

[0064] It should be noted that the storage area 313 must be compatible with the structure of the decorative panel 32 , the map pocket formed by the two must have an upward placement opening, and part of the outer edge of the decorative panel 32 must be connected to part of the outer edge of the storage area 313 .

[0065] It should be noted that the decorative panel 32 is an integrally formed structure.

[0066] See also Figure 4 On the basis of the above embodiment, the upper connecting portion 321 includes a shielding portion 322 and a mounting portion 323 connected sequentially from front to back; the front end of the shielding member 5 is fixed to the mounting portion 323 through the rotating shaft structure 51; the shielding portion 322 protrudes outward relative to the mounting portion 323, and the shielding portion 322 is used to shield the rotating shaft structure 51.

[0067] In this embodiment, the upper connecting portion 321 is divided into a shielding portion 322 and a mounting portion 323. The shielding portion 322 protrudes outward relative to the mounting portion 323, and the inner surface of the shielding portion 322 is roughly flush with the inner surface of the shielding member 5 and the inner surface of the decorative panel 32. On the one hand, the mounting portion 323 is recessed outward to facilitate the assembly of the rotating shaft structure 51. On the other hand, the shielding portion 322 also serves to shield the rotating shaft structure 51, thereby improving the overall aesthetic performance of the door guard plate 3.

[0068] In some embodiments, the guard plate body 31 may also be Figure 3 The structure shown, see Figure 3 A supporting boss 314 protruding inward is provided on the guard plate body 31 above the first avoidance hole 312 , the shielding member 5 is located directly below the supporting boss 314 , and the inner surface of the shielding member 5 is flush with the inner surface of the supporting boss 314 .

[0069] Preferably, the supporting boss 314 is located between the first avoidance hole 312 and the third avoidance hole 316. The supporting boss 314 between the third avoidance hole 316 and the first avoidance hole 312 is used to isolate the third avoidance hole 316 from the first avoidance hole 312, increase the visual height of the shielding member 5, and enhance the aesthetic performance of the door guard plate 3; on the other hand, the supporting boss 314 also serves as a handhold. When the passenger pulls the door handle 7, the hand can be placed on the upper supporting surface 315 to support the hand, thereby saving effort.

[0070] Specifically, the upper supporting surface 315 is parallel to the front-rear direction of the vehicle body, or the upper supporting surface 315 is inclined downward from front to rear relative to the front-rear direction of the vehicle body.

[0071] In some embodiments, the above-mentioned hinge structure 4 can be adopted as follows Figure 5 and Figure 6 The structure shown, see Figure 5 and Figure 6 The center hinge structure 4 includes a door armrest 41 and a center hinge body 42. The door armrest 41 is located inside the first avoidance area 311. The center hinge body 42 is fixedly mounted inside the door armrest 41. The front end of the center hinge body 42 extends out of the door armrest 41, passes through the first avoidance hole 312, and is connected to the door inner panel 1. The rear end of the center hinge body 42 is connected to the vehicle body pillar 2.

[0072] Specifically, the front end of the middle hinge body 42 is fixedly connected to the door inner panel 1 via a front fixing structure 44 , and the rear end of the middle hinge body 42 is fixedly connected to the vehicle body pillar 2 via a rear fixing structure 43 .

[0073] The middle hinge body 42 is arranged inside the door armrest 41, and the front end of the middle hinge body 42 extends out of the door armrest 41 and is fixedly connected to the door inner panel 1, and the rear end also extends out of the door armrest 41 and is fixedly connected to the vehicle body pillar 2. On the one hand, the door armrest 41 can be limited and fixed with the help of the middle hinge body 42, and there is no need to add an additional mounting structure to the door armrest 41, which improves the self-strength of the door armrest 41, and there is no need to avoid the door armrest 41 on the door guard plate 3, which improves the self-strength of the door armrest 41; on the other hand, the middle hinge body 42 can also be hidden inside the door armrest 41. The middle hinge body 42 is both hidden and does not require additional space, thereby improving the comfort performance of the entire vehicle.

[0074] See also Figure 5 Based on the above embodiment, the inner outer surface of the door armrest 41 is a curved surface 413. In the front-to-rear direction of the vehicle body, the middle part of the curved surface 413 protrudes toward the inside of the vehicle body relative to the front and rear ends; the rear end of the shielding member 5 is in rolling contact with the curved surface 413.

[0075] Since the inner outer surface of the door armrest 41 is a curved surface 413 , when the middle hinge structure 4 swings, the curved surface 413 can more easily push the shielding member 5 to swing around the hinge end, making the shielding member 5 swing more naturally.

[0076] In addition, the rear end of the shielding member 5 is in rolling contact with the curved surface 413 , which can reduce friction therebetween and further reduce abnormal noise.

[0077] Preferably, based on the above embodiment, the door armrest 41 can be Figure 6 The structure shown, see Figure 6 The door armrest 41 includes a base 411 and a cover 412. The central hinge body 42 is fixedly mounted within the base 411. The base 411 extends through both ends along its length, allowing both ends of the central hinge body 42 to extend out of the door armrest 41. The base 411 also has an upward-facing placement opening. The cover 412 is mounted over the base 411 to seal it.

[0078] Among them, the base 411 is fixedly connected to the middle hinge body 42 through several groups of positioning structures 45, and the base 411 is connected to the cover plate 412 through several groups of locking structures 46. The positioning structure 45 can realize the alignment of the base 411 and the middle hinge body 42, and the locking structure 46 can realize the detachable connection between the cover plate 412 and the base 411, thereby eliminating the need to install the door armrest 41, avoiding the impact of the excessive width of the door armrest 41 on the interior space of the vehicle, and ensuring the assembly efficiency of the vehicle interior panels.

[0079] Preferably, the locking structure 46 can be a bolt (the bolt cooperates with the cover plate 412 opened on the cover plate 412 to achieve locking), and the positioning structure 45 can be a positioning column (the positioning column cooperates with the positioning hole opened on the middle hinge body 42 to achieve positioning).

[0080] In addition, the upper side of the cover plate 412 is connected to a skin-friendly surface sheet 414 . The skin-friendly surface sheet 414 has skin-friendly properties and is usually made of leather in actual production to improve the comfort of people in the car when placing their arms.

[0081] In some embodiments, a reserved groove is provided on the upper surface of the cover plate 412, and the opening area of ​​the reserved groove is smaller than the surface area of ​​the skin-friendly surface sheet 414; and when the skin-friendly surface sheet 414 and the cover plate 412 are connected, the cover plate 412 can cover the reserved groove, thereby avoiding contact between the arm and the opening edge of the reserved groove, and further avoiding the discomfort caused by the contact.

[0082] It should be noted that, during actual preparation, the reserved groove may be filled with foam material to further improve the comfort of the lower area of ​​the skin-friendly surface sheet 414 when used to rest the arms.

[0083] In some embodiments, the vehicle body pillar 2 may also be Figure 2 and Figure 7 The structure shown, see Figure 2 and Figure 7 A second avoidance hole 21 is provided on the vehicle body pillar 2 , and a rear fixing structure 43 is provided in the second avoidance hole 21 ; the rear end of the middle hinge body 42 extends out of the door armrest 41 and is connected to the rear fixing structure 43 .

[0084] The second avoidance hole 21 is used to avoid the rear end of the middle hinge body 42 so that the rear end of the middle hinge body 42 is connected to the rear fixing structure 43 , and the rear fixing structure 43 is hidden outside the vehicle body pillar 2 .

[0085] Preferably, see Figure 2 and Figure 7 A forward-extending blocking boss 22 is provided on the vehicle body pillar 2 above the second avoidance hole 21, and the rear end of the middle hinge body 42 is located directly below the blocking boss 22; the upper half of the rear end surface of the door armrest 41 abuts against the outer surface of the blocking boss 22, and the lower half of the rear end surface of the door armrest 41 matches the inner hole wall of the second avoidance hole 21; the rear end of the door armrest 41 is used to block the second avoidance hole 21.

[0086] A forward-extending shielding boss 22 is provided above the second avoidance hole 21 , which serves as the upper edge of the second avoidance hole 21 and can overlap with the rear end of the door armrest 41 , thereby reducing the abrupt feeling of the rear end of the door armrest 41 connecting with the second avoidance hole 21 , thereby improving the aesthetic performance of the vehicle body pillar 2 .

[0087] Based on the same inventive concept, an embodiment of the present application further provides a vehicle, comprising the above-mentioned vehicle sliding door system.

[0088] The vehicle provided by the present invention adopts the above-mentioned vehicle sliding door system, and a first avoidance area 311 and a first avoidance hole 312 are set on the door guard plate 3 to avoid the middle hinge structure 4 without hindering the movement of the middle hinge structure 4; in addition, a covering member 5 is provided on the inner side of the first avoidance hole 312, and the front end of the covering member 5 is hinged to the door guard plate 3, and the rear end of the covering member 5 is in contact with the middle hinge structure 4. When the middle hinge structure 4 moves, the rear end of the covering member 5 follows the movement of the middle hinge structure 4, so that the covering member 5 itself swings around its front end. The covering member 5 cooperates with the middle hinge structure 4 to always cover the first avoidance hole 312 and prevent the first avoidance hole 312 from leaking out, thereby not affecting the appearance performance of the door guard plate 3 and enhancing the overall exquisiteness of the door.

[0089] 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
