The sealing strip of the related art is only suitable for the plug door with the driving mechanism installed above the door opening. When the driving mechanism is installed on the lower body, the length of the door body will be lengthened and the height of the threshold will remain unchanged. At the same time, there will be a certain gap between the door body and the threshold, and the sealing effect will be poor.

In some embodiments of the present utility model, as shown in Fig. 19-21, a threshold sealing strip 122 may be provided on the surface of the door body 13 facing the threshold 12, and the threshold sealing strip 122 is inside and outside when the door body 13 closes the door opening 111. Direction is compressed on the threshold 12 by the door body 13 . Specifically, the threshold sealing strip 122 may have a certain degree of elasticity. When the door body 13 closes the door opening 111, the threshold sealing strip 122 is squeezed in the inner and outer directions and pressed between the door body 13 and the threshold 12 to seal the door body 13. and threshold 12. Thereby, the sealing of the gap between the door body 13 and the threshold 12 can be realized to prevent air leakage in the car body, and the seal can also have a certain buffering effect to reduce the impact force between the door body 13 and the threshold 12 when closing the threshold 12 .

In some embodiments of the present utility model, the threshold 12 can be configured with a vertical sealing surface 1211 facing the door body 13. Optionally, the threshold 12 can be provided with a retaining edge 121 extending downward, and the vertical sealing surface 1211 formed on the blocking edge 121 . When the door body 13 closes the door opening 111 , the threshold sealing strip 122 abuts against the blocking edge 121 and cooperates with the vertical sealing surface 1211 to seal.

When the door body 13 closes the door opening 111, the threshold sealing strip 122 is pressed against the vertical sealing surface 1211 by the door body 13 in the internal and external direction, and when the door body 13 opens the door opening 111, the door body 13 is separated from the threshold 12.

That is to say, when the door body 13 closes the door opening 111, the compression amount of the door sill sealing strip 122 in the inner and outer direction can be 1-5mm, so that the door sill sealing strip 122 can be firmly pressed on the vertical sealing surface 1211, so that The sealing effect between the threshold 12 and the door body 13 is guaranteed. Optionally, the amount of interference between the rocker sealing strip 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 door sill sealing strip 122 and the vertical sealing surface 1211 in the inner and outer directions can be 3mm, so as to meet the sealing requirements of low-speed vehicles.

In some embodiments of the present utility model, a sealing profile 136 may be provided on the door body 13 , and the threshold sealing strip 122 is installed on the sealing profile 136 . Thus, it is beneficial for the door sill sealing strip 122 to be installed on the door body 13 . As shown in Figure 20, the sealing profile 136 is installed in the door body 13, and the part of the threshold sealing strip 122 extends into the door body 13 to cooperate with the sealing profile 136, so that not only the overall aesthetics of the door body 13 can be guaranteed, but also the door body 13 When the door opening 111 is closed, it can also prevent the sealing profile 136 and the threshold 12 from not being tightly sealed when the door body 13 closes the door opening 111 due to the sealing profile 136 .

Optionally, a slot 1361 may be provided on the sealing profile 136 , and a clip 1221 may be provided on the door sill sealing strip 122 , and the clip 1221 is clipped and bonded in the slot 1361 . Through the cooperation of the clamping head 1221 and the clamping groove 1361 , it is possible to prevent the door sill sealing strip 122 from moving when it rubs against the door sill 12 . Optionally, as shown in FIG. 20 , the chuck 1221 can be interference-fitted in the groove 1361 , so as not only to realize the sealing of the sealing profile 136 , but also to facilitate the installation and disassembly of the chuck 1221 and the sealing profile 136 .

As shown in Figure 19 and Figure 20, the sealing profile 136 is installed in the door body 13, and the door sill sealing strip 122 includes a clip 1221 and a sealing part 1222, wherein, one end of the clip 1221 is suitable for engaging in the slot 1361, and the sealing The part 1222 is connected to the other end of the clamping head 1221 , and the door sill sealing strip 122 is installed in cooperation with the clamping groove 1361 through the clamping head 1221 , and is pressed against the vertical sealing surface 1211 through the sealing part 1222 . In the example shown in Figure 21. The cross-section of the sealing portion 1222 in the internal and external direction is formed into a ring, so as not only to meet the sealing requirements, but also to avoid rigid collision between the door body 13 and the threshold 12 during installation or movement.

In some specific examples of the present utility model, the surface of the door sill weather strip 122 facing the door sill 12 can be configured in a serrated shape, thus, when the door sill weather strip 122 is pressed against the vertical sealing surface 1211, the door sill seal can be reduced. The strip 122 squeezes the contact area with the vertical sealing surface 1211, thereby reducing 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 motion track contains a section of curve, that is, when switching between the inner and outer directions and the left and right directions, the door body 13 When it is about to close in place, it will move along this curve, so the threshold sealing strip 122 on the door body 13 will have a certain sliding friction with the threshold 12 . The larger the interference amount and the contact area, the greater the friction force, and the greater the force required to close the door. The serrated sealing strip can effectively reduce the contact area and friction force.

Optionally, the sawtooth texture may extend in left and right directions. That is, the sawtooth texture can extend along the length of the door sill 12 , so as to realize multiple seals of the door sill weather strip 122 , so as to further improve the sealing effect of the door sill weather strip 122 .

In some specific examples of the present invention, as shown in FIG. 20 , the upper edge of the door sill sealing strip 122 is higher than the door sill 12 . Thereby, thereby can avoid the collision between the door body 13 and the threshold 12 due to false collision during installation, prevent the paint surface of the door body 13 from being damaged, and ensure the integrity of the paint surface of the door head. Optionally, the height of the upper edge of the door sill sealing strip 122 may be slightly greater than the height of the door sill 12 .

In some specific embodiments of the present invention, an external emergency unlocking device 185 can be set on the edge of the door body 13 . When the door body 13 closes the door opening 111, the external emergency unlocking device 185 is squeezed between the door frame 11 and the door body 13 to seal the gap between the door frame 11 and the door body 13 and improve the sealing effect inside the door body.

In the plug door of the related art, when the door body is about to be closed, a vertical upward movement will occur, so that the support wheel and the spacer will interfere, and a vertical downward force will be applied to limit its vertical movement. sports. When the door body is about to be opened, the door body moves downward for a small distance, so that the supporting wheels are separated from the pads.

And for the sliding door that does not move vertically, it is impossible to change the distance between the support wheel and the pad by changing the height of the door body itself. If the distance between the support wheel and the spacer is adjusted to an interference value during assembly, the door panel will not be closed due to resistance. If the distance between the support wheel and the pad is adjusted to the gap value, after the door is closed, there is still no contact between the support wheel and the pad, and it is impossible to apply force to the door panel. Therefore, the above-mentioned techniques cannot play a corresponding role in this case.

In some embodiments of the present utility model, as shown in FIG. 1 and FIG. 4 , the plug door 1 can also include a door body pressing mechanism 17, which is installed on the door frame 11 and connected with the door body 13 The upper part is connected, and the door body 13 is pressed down on the door frame 11 by the door body pressing mechanism 17 when the door opening 111 is closed. Thus, the door body 13 can be closed normally, 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 compress the door body 13 without the need for the door body 13 to move upwards. Thereby, the tight fit between the door body 13 and the door frame 11 can be ensured to ensure the sealing performance of the door body 13 , and the stability of the door body 13 can also be ensured, so as to improve the comprehensive performance of the sliding door 1 .

The pressing inclined surface 1714 faces upward and is inclined relative to the horizontal direction. The pressing roller assembly 172 is installed on the door frame 11. When the door body 13 closes the door opening 111 The pressing force of the middle pressing roller assembly 172 on the pressing slope 1714 increases gradually. Thus, the pressing roller assembly 172 is pressed against the pressing inclined surface 1714. When the door body 13 closes the door opening 111, the pressing roller assembly 172 has a downward pressure on the pressing inclined surface 1714, and the door body 13 passes through the pressing support. The component 171 has been subjected to the extrusion force from the pressing roller component 172 and the supporting force of the drive mechanism 20, thereby limiting the movement of the door body 13 in the vertical direction, realizing the stability and sealing of the door body 13, and following The door body 13 closes the door opening 111, and the pressing force of the pressing roller assembly 172 on the pressing slope 1714 gradually increases to further strengthen the stability of the door body 13, making the door body 13 more stable.

Specifically, in the process of closing the door opening 111 by the door body 13, along the moving direction of the pressing roller assembly 172, the thickness of the pressing pad 1713 gradually increases, that is, the pressing inclined surface 1714 is in the moving direction of the pressing roller assembly 172. The top gradually extends upwards, so that when the door body 13 closes the door opening 111, the distance between the pressing roller assembly 172 and the pressing inclined surface 1714 gradually decreases, and the distance between the pressing pad 1713 and the pressing roller assembly 172 The extrusion force gradually increases, and the door body 13 is pressed downward by the pressing roller assembly 172, so that the door body 13 can be stabilized. Further, the lower surface of the pressing pad 1713 is arranged horizontally, thereby facilitating the matching of the pressing pad 1713 with the lower wall of the pressing slot 1712 .

In some examples of the present invention, the countersunk screw is disposed adjacent to the highest point of the pressing slope 1714 . The door body 13 is compressed on the pressing inclined surface 1714, and when the door body 13 moves to the highest point of the pressing inclined surface 1714, the pressing force between the pressing roller assembly 172 and the pressing spacer 1713 is the largest, and the countersunk screw When it is close to the highest point of the pressing inclined surface 1714, the fixed connection between the pressing cushion block 1713 and the pressing support 1711 can be further strengthened to improve the stability.
