[0109] The third pin 470 passes through the L-shaped component 430, the fifth bushing 703, the first movable bracket 700, the fifth bushing 703, and the L-shaped component 430 from top to bottom.
[0110] In an exemplary implementation, such as Figure 10A and Figure 10B As shown, the first end of the support bracket 800 is mounted to the end of the first movable bracket 700 away from the strip hole 702 via the fourth pin 801, and the support bracket 800 can rotate relative to the first movable bracket 700 around the fourth pin 801.
[0111] In an exemplary implementation, such as Figure 10A and Figure 10BAs shown, the end of the first movable support 700 away from the strip hole 702 has a third mounting hole 805. The sliding door guide rail device for vehicles of this invention further includes a sixth bushing 802 fitted onto the fourth pin 801. The sixth bushing 802 includes a sixth bushing body 803 and a sixth bushing extension 804. The sixth bushing body 803 is located between the first movable support 700 and the support bracket 800 to reduce the friction between the first movable support 700 and the support bracket 800.
[0112] The sixth bushing extension 804 is located between the inner surface of the third mounting hole 805 of the first movable bracket 700 and the outer surface of the fourth pin 801 to reduce the friction between the first movable bracket 700 and the fourth pin 801.
[0113] The fourth pin 801 passes through the bearing bracket 800, the sixth bushing 802 and the first movable bracket 700 from top to bottom.
[0114] This utility model embodiment also provides a vehicle equipped with the aforementioned sliding door guide rail device for vehicles. Other components and functions of the vehicle according to this utility model embodiment are known to those skilled in the art and will not be described in detail to reduce redundancy.
[0115] The operation of the sliding door guide rail device for vehicles according to the present invention will be described below with reference to the accompanying drawings.
[0116] like Figure 11A As shown, when the sliding door 902 is in the closed state, the pusher 501 is not in contact with the first arm 410 of the rotating assembly 400, and the first gear 500 engages with the front end of the first rack portion 201 of the fixed bracket 200. The second gear 600 engages with the first gear 500 and also engages with the second rack portion 701 of the first movable bracket 700. The third pin 470 contacts the rear end of the slot 702 of the first movable bracket 700.
[0117] The opening process of sliding door 902 consists of three stages:
[0118] First stage: Under the traction of the open cable 331, the connecting bracket 320 of the moving component 300 moves backward, thereby driving the rotating component 400 and the first gear 500 to move backward, and driving the second moving bracket 310 to slide backward along the track 100.
[0119] Since the first gear 500 engages with the first rack portion 201 of the fixed bracket 200, the first gear 500 will rotate around the first pin 450 along the first rotation direction. Figure 11A Rotate clockwise.
[0120] The pusher 501 will follow the first gear 500 along the first rotation direction ( Figure 11A Rotate clockwise until the pusher 501 contacts the first arm 410 of the rotating assembly 400 (see [reference]). Figure 11B In the first stage, the second gear 600 will rotate around the second pin 460 in the second direction of rotation. Figure 11A The first movable bracket 700 rotates counterclockwise (in the same direction). Due to the engagement of the second gear 600 and the second rack portion 701, the first movable bracket 700 is driven to move backward relative to the rotating assembly 400 until the third pin 470 contacts the front end of the slot 702 in the first movable bracket 700. Through dimensional design, when the pusher 501 contacts the first arm 410 of the rotating assembly 400, the third pin 470 is precisely in contact with the front end of the slot 702 in the first movable bracket 700. At this point, the first stage ends.
[0121] In the first stage, the first movable support 700 pulls the supporting support 800 backward, which in turn pulls the sliding door 902 backward a short distance. The supporting support 800 does not rotate around the fourth pin 801 in the first stage.
[0122] The first stage causes the sliding door 902 to slide backward a short distance, which can prevent the sliding door 902 from interfering with the front door at the B-pillar position.
[0123] Second stage: After the pusher 501 contacts the first arm 410 of the rotating assembly 400, the first gear 500 continues to rotate along the first rotation direction. The pusher 501 will push the rotating assembly 400 to rotate around the first pin 450 along the first rotation direction, thereby causing the first movable bracket 700 to rotate around the first pin 450 along the first rotation direction. That is, the rotating assembly 400 and the first movable bracket 700 swing outward. This process will drive the bearing bracket 800 to rotate around the fourth pin 801 along the first direction (i.e., from...). Figures 11B to 11C This causes the sliding door 902 to swing outwards.
[0124] When the support bracket 800 rotates along the first rotation direction to its maximum distance from the track 100, the first gear 500 is no longer engaged with the first rack portion 201 of the fixed bracket 200, that is, the first gear 500 disengages from the first rack portion 201 (see...). Figure 11C At this point, the second phase ends.
[0125] Third stage: The moving component 300, rotating component 400, and first gear 500 continue to move backward until the moving component 300 reaches the rear end of the track 100. Since the first gear 500 has disengaged from the first rack portion 201, it will no longer rotate around the first pin 450, thus preventing the rotating component 400 from rotating around the first pin 450. This keeps the first moving bracket 700 and the supporting bracket 800 in place. Figure 11D The state that is, the state with the greatest distance from orbit 100.
[0126] When the moving component 300 moves to the rear end of the track 100, the sliding door 902 is fully opened.
[0127] The closing process of the sliding door 902 is as follows: Under the traction of the closing cable 332, the connecting bracket 320 of the moving component 300 moves forward. The rest of the process is the reverse of the opening process described above, and will not be described in detail here.
[0128] exist Figure 11A In one implementation scheme, when the sliding door 902 is closed, the second gear 600 directly engages with the first gear 500. Alternatively, a third gear 903 can be added between the second gear 600 and the first gear 500 for engagement. Figure 12 As shown, the first arm 410 has a fourth mounting portion 404 located between the first mounting portion 401 and the second mounting portion 402, and the third gear 903 is rotatably mounted to the fourth mounting portion 404. The third gear 903 engages with the second gear 600 and also engages with the first gear 500; that is, the second gear 600 indirectly engages with the first gear 500. When the sliding door 902 is in the closed state, the first movable bracket 700 is located outside the second gear 600. Figure 12 In the middle, when the first gear 500 is along the first rotation direction (i.e., Figure 12 When the third gear 903 rotates clockwise, it rotates along the second rotation direction (i.e., Figure 12 The first gear rotates counterclockwise, thereby driving the second gear 600 to rotate along the first rotation direction.
[0129] Figure 12 The proposed implementation increases the length of the first arm 410, thereby increasing the opening width in the width direction. Additionally, Figure 12 The implementation scheme can place the first movable support 700 on the outside of the rotating component 400, making the placement of the first movable support 700 more flexible.
[0130] like Figure 13A and Figure 13B As shown, in order to ensure that the front door 906 can open normally in the event of a side collision, a no-jam structure 907 is generally used. However, if the sliding rear door 905 is rotated directly, the rear door 905 and the front door 906 may interfere with each other at the B-pillar. Therefore, the process in the first stage described above can avoid interference between the rear door 905 and the front door 906.
[0131] When opening the car door, rotate the support bracket 800 to the outermost position to avoid the side panel and side panel trim.
