The related art sealing strip is only suitable for the sliding door of the driving mechanism installed above the door hole. When the driving mechanism is installed in the lower body, the length of the door body is lengthened, the height of the door sill is constant, and the sealing form of the related art can not meet the sealing inside the body. The requirement is that there will be a certain gap between the door body and the door sill, and the sealing effect is poor.

In some embodiments of the present invention, as shown in FIGS. 19-21, the door body 13 may be provided with a sill sealing strip 122 on the surface facing the sill 12, and the sill sealing strip 122 is in the inner and outer directions when the door body 13 closes the door opening 111. The upper door is pressed against the threshold 12 by the door body 13. Specifically, the sill sealing strip 122 may have a certain elasticity. When the door body 13 closes the door opening 111, the sill sealing strip 122 is pressed in the inner and outer directions and pressed between the door body 13 and the sill 12 to seal the door body 13. And the threshold 12. Therefore, the gap between the door body 13 and the door sill 12 can be sealed to prevent air leakage in the vehicle body, and the sealing member can also have a certain buffering effect to reduce the impact force between the door body 13 and the sill 12 when the door sill 12 is closed. .

In some embodiments of the present invention, the sill 12 may be configured with a vertical sealing surface 1211 facing the door body 13. Alternatively, the sill 12 may be provided with a downwardly extending rim 121, and the vertical sealing surface 1211 is formed. On the rim 121.

When the door body 13 closes the door opening 111, the sill sealing strip 122 is pressed against the vertical sealing surface 1211 by the door body 13 in the inner and outer directions. When the door body 13 opens the door opening 111, the door body 13 is disengaged from the sill 12. Specifically, when the door body 13 closes the door opening 111, the door body 13 moves toward the rocker 12 in the inner and outer directions, and the weather strip 122 receives pressure from the door body 13 and the rocker 12, thereby pressing the rocker weather strip 122 against the vertical sealing surface. In order to achieve the purpose of sealing on the 1211, the sill sealing strip 122 can also increase the contact area between the sill sealing strip 122 and the vertical sealing surface 1211 by closely fitting with the vertical sealing surface 1211 to further improve the sealing effect.

In order to further ensure the sealing effect of the sill sealing strip 122 and the vertical sealing surface 1211, the interference amount of the sill sealing strip 122 and the vertical sealing surface 1211 in the inner and outer directions when the door body 13 closes the door opening 111 for the sill sealing strip 122 Can be 1-5mm. That is, when the door body 13 closes the door opening 111, the amount of compression of the sill sealing strip 122 in the inner and outer directions may be 1-5 mm, so that the sill sealing strip 122 can be firmly pressed against the vertical sealing surface 1211, thereby The sealing effect between the door sill 12 and the door body 13 is ensured. Alternatively, the amount of interference between the sill seal 122 and the vertical sealing surface 1211 in the inner and outer directions may be 2-4 mm. In a specific example of the present invention, the amount of interference between the sill seal 122 and the vertical sealing surface 1211 in the inner and outer directions may be 3 mm, thereby satisfying the sealing requirements of the low speed vehicle.

In some embodiments of the invention, the door body 13 may be provided with a sealing profile 136 on which the sill sealing strip 122 is mounted. Thereby, the sill sealing strip 122 is mounted on the door body 13. As shown in FIG. 20, the sealing profile 136 is mounted in the door body 13, and a portion of the sill sealing strip 122 extends into the entry body 13 to cooperate with the sealing profile 136, thereby not only ensuring the overall aesthetics of the door body 13, but also in the door body 13 When the door opening 111 is closed, it is also possible to prevent the sealing profile 136 from being tightly sealed from the rocker 12 when the door body 13 closes the door opening 111 due to the sealing profile 136.

Optionally, the sealing profile 136 can be provided with a card slot 1361. The sill sealing strip 122 is provided with a card head 1221. The card head 1221 is card-bonded and bonded in the card slot 1361. By the engagement of the chuck head 1221 with the card slot 1361, it is possible to prevent the slamming of the sill seal 122 from rubbing against the sill. Alternatively, as shown in FIG. 20, the chuck head 1221 can be interference fit in the card slot 1361, so that not only the sealing of the sealing profile 136 but also the mounting and dismounting of the chucking head 1221 and the sealing profile 136 can be facilitated.

As shown in FIG. 19 and FIG. 20, the sealing profile 136 is mounted in the door body 13. The sill sealing strip 122 includes a chuck head 1221 and a sealing portion 1222, wherein one end of the chuck head 1221 is adapted to be engaged in the card slot 1361, and sealed. The portion 1222 is connected to the other end of the chuck 1221, and the sill sealing strip 122 is fitted to the card slot 1361 by the chuck 1221 and pressed against the vertical sealing surface 1211 by the sealing portion 1222. In the example shown in FIG. The cross section of the sealing portion 1222 in the inner and outer directions is formed in a ring shape, so that not only the sealing requirement but also the rigidity collision between the door body 13 and the rocker 12 during installation or movement can be avoided.

In some specific examples of the invention, the surface of the sill seal 122 facing the sill 12 may be configured in a zigzag shape whereby the sill seal 122 is pressed against the vertical sealing surface 1211, thereby reducing the sill seal The contact area of the 122 squeeze type with the vertical sealing surface 1211, thereby reducing the friction. Specifically, due to the self-characteristics of the plug door 1, when the door body 13 closes and opens the door opening 111, its movement track contains a curve, that is, when switching between the inner and outer directions and the left and right direction, the door body 13 is The movement along this curve is about to close when it is in place, so the sill seal 122 on the door 13 will have some sliding friction with the sill 12. The larger the amount of interference and the contact area, the greater the friction, and the greater the force required to close the door. The serrated seal can effectively reduce the contact area and reduce the friction.

Alternatively, the serrated zigzag texture may extend in the left and right direction. That is, the serrated zigzag texture can extend along the length of the sill 12, so that multiple sealing of the sill seal 122 can be achieved to further improve the sealing effect of the sill seal 122.

In some specific examples of the invention, as shown in FIG. 20, the upper edge of the sill seal 122 is higher than the sill 12. Thereby, it is possible to avoid a bump between the door body 13 and the rocker 12 due to an accidental collision during the installation process, thereby preventing the paint surface of the door body 13 from being damaged, and ensuring the integrity of the paint surface of the door head. Alternatively, the upper edge height of the sill seal 122 may be slightly greater than the height of the sill 12.

In some embodiments of the invention, the door body 13 may be provided with a door frame seal on the rim. When the door body 13 closes the door opening 111, the door frame sealing ring is pressed between the door frame 11 and the door body 13 to seal the gap between the door frame 11 and the door body 13, thereby improving the sealing effect inside the body.

In the related art sliding door, when the door body is about to be closed, a vertical upward movement occurs, causing the support wheel and the spacer to interfere, thereby applying a vertical downward force to limit the vertical direction thereof. motion. When the door is about to open, the door will move downward a small distance, so that the support wheel is separated from the block.

For a sliding door that does not move in the vertical direction, the distance between the support wheel and the spacer cannot be changed by the change in the height of the door itself. If the distance between the support wheel and the block is adjusted to an interference value during assembly, the door panel may not be closed due to resistance. If the distance between the support wheel and the spacer is adjusted to the gap value, after the door is closed, the support wheel and the spacer are still not in contact with each other, and the door panel cannot be applied with force. Therefore, the above technique does not play a corresponding role in this case.

In some embodiments of the present invention, as shown in FIGS. 1 and 4, the plug door 1 may further include a door body pressing mechanism 17 mounted on the door frame 11 and with the upper portion of the door body 13. When connected, the door body 13 is pressed down to the door frame 11 by the door body pressing mechanism 17 when the door opening 111 is closed. Thereby, the door body 13 can be normally closed, and when the door body 13 is about to close the door opening 111, the door body pressing mechanism 17 cooperates with the door body 13 to press the door body 13 without the door body 13 moving upward. Therefore, the tight fit of the door body 13 and the door frame 11 can be ensured to ensure the sealing property of the door body 13, and the stability of the door body 13 can be ensured to improve the overall performance of the sliding door 1.

A door body pressing mechanism 17 according to a specific embodiment of the present invention will now be described with reference to the following.
