In the guide rail of the sliding plug door in the related art, due to the fact that the roller and the guide rail are difficult to mount, mounting errors are possible, the guide rail wheel needs to be mounted on the guide rail firstly, then the guide roller and the guide swing arm are mounted on the door frame, at the moment, a large number of parts are difficult to adjust to proper positions, and operation is complex in the adjusting process, and mounting is difficult.

In the bearing rail 141 according to the embodiment of the present invention, the guide roller 1434 is allowed to be adapted to enter and exit the bearing guide groove 1411 through the roller mounting opening 1412 by providing the roller mounting opening 1412 on the sidewall of the bearing guide groove 1411, and the blocking plate 142 is detachably provided at the roller mounting opening 1412 to be adapted to open or close the roller mounting opening 1412. Thus, in the assembling process of the sliding plug door 1, the guide roller 1434 can pass through the roller assembling opening 1412 to enter the bearing guide groove 1411, and then the roller assembling opening 1412 is closed by the baffle 142, so that the guide roller 1434 can smoothly enter the bearing guide groove 1411 to facilitate the installation of the guide roller 1434, when the guide roller 1434 is disassembled, the roller assembling opening 1412 can be disassembled firstly, and then the guide roller 1434 is led out from the roller assembling opening 1412, thereby facilitating the disassembly of the guide roller 1434 and the bearing rail 141.

In some embodiments of the present invention, the barrier 142 may further include a mounting part 1421 and a blocking part 1424, the mounting part 1421 is detachably mounted on the body 1411, and the blocking part 1424 is provided on the mounting part 1421 and is filled in the roller mounting opening 1412. Thus, the flapper 142 can be detachably mounted to the body 1411 by the mounting portion 1421, and when the flapper 142 is mounted to the body 1411, the blocking portion 1424 faces the roller mounting opening 1412 and can fill the roller mounting opening 1412. As shown in fig. 12, there may be two mounting portions 1421, and the two mounting portions 1421 are respectively disposed at both ends of the baffle 142. The blocking portion 1424 is provided between two mounting portions 1421, and the two mounting portions 1421 are respectively fitted to portions of the load rail 141 on both sides in the longitudinal direction of the roller mounting opening 1412. So that the coupling strength of the baffle 142 and the body 1411 can be enhanced.

Alternatively, the surface of the blocking portion 1424 facing the interior of the load-bearing channel 1411 can be flush with the interior walls of the load-bearing channel 1411. Therefore, when the guide roller 1434 rotates in the bearing guide groove 1411 and moves along the length direction of the bearing groove, the guide roller 1434 can be ensured to be in close contact with the inner side wall of the bearing guide groove 1411, and smooth movement of the guide roller 1434 in the bearing guide groove 1411 is facilitated.

Alternatively, the length of the mounting part 1421 may be greater than the length of the roller mounting opening 1412, and the width of the mounting part 1421 is greater than the height of the roller mounting opening 1412. It can be appreciated that, when the barrier 142 is mounted at the roller mounting opening 1412, the length direction of the mounting part 1421 is identical to the length direction of the roller mounting opening 1412, and the width of the mounting part 1421 is matched with the height of the roller mounting opening 1412, so that the roller mounting opening 1412 is completely closed by the mounting part 1421, and the connection of the mounting part 1421 with the body 1411 is also facilitated.

Further, the length of the blocking part 1424 may be smaller than the length of the mounting part 1421 and adapted to the length of the roller mounting opening 1412, the width of the blocking part 1424 is smaller than the width of the mounting part 1421 and adapted to the width of the roller mounting opening 1412, and the depth of the roller mounting opening 1412 is adapted to the thickness of the blocking part 1424. This ensures that the blocking portion 1424 can be filled in the roller mounting opening 1412, and at the same time, the surface of the blocking portion 1424 facing the inside of the load-bearing channel 1411 can be flush with the inner wall of the load-bearing channel 1411, and the gap between the surface of the blocking portion 1424 facing the inside of the load-bearing channel 1411 and the two planes of the inner wall of the load-bearing channel 1411 can be small, so that the guide roller 1434 has almost no noise at the critical point of the two planes when the surface of the blocking portion 1424 facing the inside of the load-bearing channel 1411 rolls with the inner wall of the load-bearing channel 1411.

In some examples of the present invention, as shown in fig. 12, both ends of the mounting part 1421 may be respectively provided with mounting tongues 1422, and the mounting tongues 1422 are detachably mounted on the body 1411 by a threaded fastener. Thereby securing the fixing strength of the mounting part 1421 to the body 1411. It is understood that the threaded fastener may be a screw, a bolt, or the like, and the present invention is not particularly limited thereto, and the mounting tongue 1422 may be detachably fixed to the body 1411 by the threaded fastener. In order to enhance the structural strength of the mounting portion 1421, as shown in fig. 15 and 16, a surface of the mounting tongue 1422 facing away from the body 1411 may be provided with a rib 1423, so as to enhance the structural strength of the baffle 142 and also enhance the fixing strength between the mounting portion 1421 and the body 1411.

In some examples of the invention, the roller mounting port 1412 may be disposed adjacent an end of the body 1411. Thereby reducing the noise of the roller when rotating in the load rail 141. For example, the roller fitting opening 1421 may be disposed at an end where the guide roller 1434 is located when the door 13 is closed, and since the door closing speed is reduced when the door 13 is about to be closed, the roller fitting opening 1412 is disposed adjacent to an end of the body 1411 so as to reduce the rolling noise of the guide roller 1434 at a position where the surface of the blocking portion 1424 facing the inside of the load-bearing guide groove 1411 is spaced from the inner wall of the load-bearing guide groove 1411.

In some embodiments of the invention, the body 1411 can have a horizontal rim 1413 that extends horizontally toward the exterior of the load bearing channel 1411, and the load bearing roller 1433 can fit over a lower surface of the horizontal rim 1413. In other words, the horizontal edge 1413 of the body 1411 abuts against the bearing roller 1433 and is carried by the bearing roller 1433, and the bearing roller 1433 rolls along the horizontal edge 1411 along the length direction of the body 1413.

In some embodiments of the present invention, one end of the body 1411 is provided with a first stopping plate 1414 for stopping the guiding roller 1434 from coming out of the bearing guide 1411 from one end of the body 1411, and the other end of the body 1411 is provided with a second stopping plate 1415 for stopping the guiding roller 1434 from coming out of the bearing guide 1411 from the other end of the body 1411. Therefore, the two ends of the bearing guide groove 1411 can be respectively blocked by the first stopping sheet 1414 and the second stopping sheet 1415, and when the guide roller 1434 rolls in the bearing guide groove 1411, the guide roller 1434 can be prevented from being separated from the two ends of the bearing guide groove 1411 by the first stopping sheet 1414 and the second stopping sheet 1415.

Optionally, a certain gap may be provided between the guide roller 1452 and the guide rollers 1452 on both sides, so that when the door 13 is moved in a turning direction between the inner and outer directions and the left and right directions, the gap may be suitable for adaptive adjustment when the door 13 is moved in a turning direction, so that the door 13 moves more smoothly and stably.

As shown in fig. 11, a first blocking portion 1443 is provided at one end of the horizontal portion 1441 or one end of the vertical portion 1442 for blocking the guide roller 1452 from being separated from the vertical portion 1442 from one end of the vertical portion 1442, and a second blocking portion 1444 is provided at the other end of the horizontal portion 1441 or the other end of the vertical portion 1442 for blocking the guide roller 1452 from being separated from the vertical portion 1442 from the other end of the vertical portion 1442. Thus, the roller is prevented from being separated from both ends of the guide rail 144 by the first and

second stoppers

The upper end of the first fitting portion 152 can be positioned adjacent to the second fitting portion 153, so as to make the structure of the first section bar 15 more compact and also suitable for cooperating with the body 1411 of the load-bearing rail 141.

Alternatively, several profile ribs 1522 can be provided on the surface of the first mounting portion 152 facing away from the first horizontal mounting surface 1521. Thereby, the structural strength of the first fitting portion 152 can be reinforced, and thus, the structural strength of the first profile 15 can be improved.

Optionally, an upper hollow cavity 1523 may be formed between the first assembling portion 152 and the first arc portion 151, so that the structure of the first profile 15 may be simplified, the material cost of the first profile 15 may be reduced, and the weight of the driving mechanism 20 may also be reduced. As shown in fig. 17 and 18, a hollow-out space 1533 is also formed between the second fitting portion 153 and the first arc portion 151. Thereby, the material cost of the first section bar 15 can be further reduced, and the load bearing of the driving mechanism 20 can be reduced

In some embodiments of the present invention, the upper portion of the door body 13 is further provided with a second profile 16, the second profile 16 is configured with a downward horizontal mounting surface 1621, and the guide rail 144 is mounted on the horizontal mounting surface 1621. Therefore, the guide rail 144 can be installed on the door body 13 through the matching installation of the second section bar 16 and the guide rail 144, the installation of the guide rail 144 is facilitated, the assembling strength of the guide rail 144 and the door body 13 can be improved, and meanwhile, the second section bar 16 also has a certain guiding function, so that a constructor can clearly determine the installation position of the guide rail 144.

Alternatively, the first profile 15 and the second profile may be integrally formed. The mounting steps of the first profile 15 and the second profile 16 can thus be simplified, facilitating the mounting of the first profile 15 and the second profile 16.

The sealing strip of the related art is only suitable for the sliding plug door with the driving mechanism arranged above the door opening, when the driving mechanism is arranged on the lower vehicle body, the length of the door body is lengthened, the height of the threshold is unchanged, the sealing form of the related art cannot meet the requirement of sealing in the upper vehicle body, meanwhile, a certain gap can exist between the door body and the threshold, and the sealing effect is poor.

In some embodiments of the present invention, as shown in fig. 19 to 21, a surface of the door body 13 facing the rocker 12 may be provided with a rocker seal 122, and the rocker seal 122 is pressed against the rocker 12 by the door body 13 in the inward and outward directions when the door body 13 closes the door opening 111. Specifically, threshold weather strip 122 may have a certain elasticity, and when door body 13 closes door opening 111, threshold weather strip 122 is pressed and compressed in the inward and outward direction between door body 13 and threshold 12 to seal door body 13 and threshold 12. Therefore, the gap between the door body 13 and the threshold 12 can be sealed, air leakage in the vehicle body is prevented, and meanwhile, the sealing piece also has a certain buffering effect so as to reduce impact force between the door body 13 and the threshold 12 when the door body 13 closes the threshold 12.

In some embodiments of the present invention, the threshold 12 may be configured with a vertical sealing surface 1211 facing the door body 13, and optionally, the threshold 12 may be provided with a downwardly extending blocking edge 121, and the vertical sealing surface 1211 is formed on the blocking edge 121. When the door 13 closes the door opening 111, the threshold sealing strip 122 abuts against the stop edge 121 and is sealed by the vertical sealing surface 1211.

When the door 13 closes the door opening 111, the threshold weather strip 122 is pressed against the vertical sealing surface 1211 by the door 13 in the inward and outward directions, and when the door 13 opens the door opening 111, the door 13 is separated from the threshold 12. Specifically, when the door body 13 closes the door opening 111, the door body 13 moves toward the door sill 12 in the inward and outward directions, and the sealing strip 122 is pressed by the door body 13 and the door sill 12, so that the door sill sealing strip 122 is pressed against the vertical sealing surface 1211 to achieve the sealing purpose, and meanwhile, the contact area between the door sill sealing strip 122 and the vertical sealing surface 1211 can be increased by the door sill sealing strip 122 being tightly matched with the vertical sealing surface 1211, so as to further improve the sealing effect.

In order to further ensure the sealing effect of threshold weather strip 122 and vertical sealing surface 1211, for threshold weather strip 122, when door 13 closes door opening 111, the interference amount between threshold weather strip 122 and vertical sealing surface 1211 in the inward and outward directions may be 1-5 mm. That is, when the door 13 closes the door opening 111, the compression amount of the threshold weather strip 122 in the inward and outward direction may be 1 to 5mm, so that the threshold weather strip 122 can be firmly pressed against the vertical sealing surface 1211, and the sealing effect between the threshold 12 and the door 13 can be ensured. Alternatively, the amount of interference of threshold seal 122 with vertical seal surface 1211 in the inward and outward direction may be 2-4 mm. In one specific example of the present invention, the amount of interference of the threshold weather strip 122 with the vertical sealing surface 1211 in the inward and outward direction may be 3mm, so that the sealing requirement of the low-speed vehicle can be satisfied.

In some embodiments of the present invention, door 13 may be provided with a seal profile 136, and threshold seal 122 is mounted on seal profile 136. Thereby facilitating the installation of threshold seal 122 on door body 13. As shown in fig. 20, the sealing profile 136 is installed in the door body 13, and a portion of the threshold sealing strip 122 extends into the door body 13 to be matched with the sealing profile 136, so that not only can the overall aesthetic degree of the door body 13 be ensured, but also when the door body 13 closes the door opening 111, the sealing profile 136 can be prevented from being loosely sealed with the threshold 12 when the door body 13 closes the door opening 111 due to the sealing profile 136.

Optionally, a clamping groove 1361 may be provided on the seal profile 136, a clamping head 1221 is provided on the threshold seal strip 122, and the clamping head 1221 is clamped and bonded in the clamping groove 1361. Through the cooperation of chuck 1221 and slot 1361, the play of threshold seal 122 when rubbing against threshold 12 is avoided. Alternatively, as shown in fig. 20, the chuck 1221 may be in an interference fit in the slot 1361, so that not only the seal of the seal profile 136 can be achieved, but also the installation and the removal of the chuck 1221 and the seal profile 136 are facilitated.

As shown in fig. 19 and 20, the sealing profile 136 is mounted in the door body 13, and the threshold sealing strip 122 includes a clip 1221 and a sealing portion 1222, wherein one end of the clip 1221 is adapted to be clipped into the slot 1361, the sealing portion 1222 is connected to the other end of the clip 1221, and the threshold sealing strip 122 is mounted by the clip 1221 in cooperation with the slot 1361 and pressed against the vertical sealing surface 1211 by the sealing portion 1222. In the example shown in fig. 21. The cross section of the sealing portion 1222 in the inward and outward direction is formed in a ring shape, so that not only the sealing requirement can be satisfied, but also the rigid collision between the door body 13 and the threshold 12 during the installation or movement process can be avoided.

In some specific examples of the present invention, the surface of threshold seal 122 facing threshold 12 may be configured to be serrated, whereby when threshold seal 122 is pressed against vertical sealing surface 1211, the contact area of threshold seal 122 with vertical sealing surface 1211 in a squeezing manner is reduced, thereby reducing friction. Specifically, due to the characteristics of the sliding plug door 1, when the door body 13 closes and opens the door opening 111, the motion trajectory of the door body 13 includes a section of curve, that is, when the door body 13 moves in a switching manner between the inside and outside directions and the left and right directions, and the door body 13 moves along the section of curve immediately before being closed, so that the threshold sealing strip 122 on the door body 13 generates a certain sliding friction with the threshold 12. The larger the interference amount and the contact area, the larger the friction force is, the larger the force is needed for closing the door, and the serrated sealing strip can effectively reduce the contact area and the friction force.

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

In some specific examples of the invention, as shown in fig. 20, the upper edge of threshold seal 122 is higher than threshold 12. Therefore, collision caused by error collision between the door body 13 and the doorsill 12 in the installation process can be avoided, the paint surface of the door body 13 is prevented from being damaged, and the completeness of the paint surface of the door head is guaranteed. Alternatively, the height of the upper edge of threshold seal 122 may be slightly greater than the height of threshold 12.

In some embodiments of the present invention, a door frame sealing ring may be sleeved on the edge of the door 13. When the door 13 closes the door opening 111, the door frame sealing ring is squeezed between the door frame 11 and the door 13 to seal the gap between the door frame 11 and the door 13, so that the sealing effect inside the refrigerator body is improved.

According to the sliding plug door in the related art, the door body can move vertically upwards when being closed, so that the supporting wheels and the cushion blocks are interfered, a vertical downward force is applied, and the vertical movement of the sliding plug door is limited. When the door body is about to be opened, the door body can move downwards for a small distance, so that the supporting wheels are separated from the cushion blocks.

For the sliding plug door which does not move in the vertical direction, the distance between the supporting wheel and the cushion block cannot be changed through the change of the height of the door body. If the distance between the support wheel and the cushion block is adjusted to an interference value during assembly, the door panel cannot be closed due to resistance. If the distance between the supporting wheel and the cushion block is adjusted to be a clearance value, the supporting wheel and the cushion block are still not in contact after the door is closed, and force cannot be applied to the door panel. Therefore, the above-described technique cannot function correspondingly in this case.

In some embodiments of the present invention, as shown in fig. 1 and 4, the sliding plug door 1 may further include a door pressing mechanism 17, the door pressing mechanism 17 is installed on the door frame 11 and connected to an upper portion of the door 13, and the door 13 is pressed downward on the door frame 11 by the door pressing mechanism 17 when the door 13 closes the door opening 111. Therefore, 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 is matched with the door body 13 to press the door body 13 without the need of upward movement of the door body 13, so that the tightness of the door body 13 can be ensured by the close matching of the door body 13 and the door frame 11, the stability of the door body 13 can be ensured, and the comprehensive performance of the sliding plug door 1 can be improved.

Reference is now made to a description of the door pressing mechanism 17 according to an embodiment of the present invention.
