Fig. 9 is a schematic view of a part of the structure of fig. 6, fig. 10 is a schematic exploded view of the structure of fig. 9, and fig. 11 is a schematic view of the first rail 141 of fig. 10.

Referring to fig. 9 to 11, each of the first rail 141 and the second rail 142 is provided with a rack portion 16 along a length direction thereof, and the rack portion 16 is a part of the first rail 141 and the second rail 142. It should be understood that in fig. 9-11, only schematic diagrams of the mating relationship between the first rail 141 and the first rail 151 are shown, and reference may be made to the mating relationship between the first rail 141 and the first rail 151 for the mating relationship between the second rail 142 and the second rail 152. The following further describes the relationship between the first rail 141 and the first rail 151 as an example:

the rack portion 16 may be integrally formed with the other portion of the first rail 141, or may be provided separately. The length of the rack portion 16 may be equal to the length of the first rail 141 or less than the length of the first rail 141. The first rail 141 has a first side and a second side opposite to each other, the first side of the first rail 141 is fixed to a sidewall of the liner 12, the second side of the first rail 141 is provided with a rack portion 16, and the rack portion 16 may be specifically disposed at a bottom of the first rail 141.

Fig. 12 is an enlarged schematic view of the structure of the area a in fig. 7.

Referring to fig. 7-9-12, the first rail 151 and the second rail 152 are each provided with a rotatable gear 17, and the gear 17 is configured to mesh with the rack portion 16 to roll along the rack portion 16, so that the first rail 151 moves along the length direction of the first rail 141, and the second rail 152 moves along the length direction of the second rail 142.

In fig. 7, the gear 17 is shown disposed on the first slide rail 151, and the manner in which the gear 17 is disposed on the second slide rail 152 may be further described with reference to the description in which the gear 17 is disposed on the first slide rail 151, taking the example in which the gear 17 is disposed on the first slide rail 151 as an example: the gear 17 may be disposed at a rear end of the first rail 151, and the gear 17 does not move relative to the first rail 151 when rotating along its rotation axis, so that the first rail 151 rolls on the rack portion 16 of the first rail 141 through the gear 17, so as to move the first rail 151 in a length direction of the first rail 141. The first rail 151 also has a first side and a second side opposite to each other, the first side of the first rail 151 is opposite to the second side of the first rail 141, and the second side of the second rail 152 is provided with the gear 17. Wherein the bottom of the gear 17 may be raised with respect to the bottom wall of the first rail 151, such that the first rail 141 is supported on the gear 17 portion of the first rail 141 by the gear 17, i.e. the storage drawer 13 is supported on the gear 17 portion of the first rail 141 by the gear 17.

In combination with the above, when the storage drawer 13 is pushed and pulled, the storage drawer 13 slides on the first rail 141 via the first rail 151, and the second rail 152 slides on the second rail 142, thereby realizing the front-back displacement in the storage compartment 121. In addition, under normal conditions, the first slide rail 151 and the second slide rail 152 move synchronously, and at this time, the first slide rail 151 is always parallel to the first guide rail 141, and the second slide rail 152 is always parallel to the second guide rail 142.

Fig. 13 is a schematic diagram illustrating the matching relationship between the first rail 151 and the second rail 152 and the first rail 141 and the second rail 142.

Referring to fig. 13, due to the structural strength or improper pushing and pulling of the user, the first sliding rail 151 and the second sliding rail 152 may not move synchronously, so that the first sliding rail 151 and the second sliding rail 152 may incline during moving. At this time, the ends of the first slide rail 151 and the second slide rail 152 are located one after the other, so that the first slide rail 151 and the second slide rail 152 cannot move normally, and the storage drawer 13 cannot be pushed and pulled normally.

Fig. 14 is an enlarged schematic view of the structure of the region B in fig. 11.

In connection with fig. 14, the rack portion 16 of the first rail 141 is provided with a first reset section 18 without teeth, the first reset section 18 being connected to other sections of the rack portion 16 provided with teeth, the gear 17 being movable from other sections of the rack portion 16 to the first reset section 18 and from the first reset section 18 to other sections. The top surface of the first reset segment 18 may be provided as a planar surface, and the top surface of the first reset segment 18 is lower than the other segments of the rack portion 16, which may be flush with the bottoms of the teeth of the other segments.

In some application scenarios, referring to fig. 13, the first slide rail 151 and the second slide rail 152 do not move synchronously, so that the gear 17 at the rear end of the first slide rail 151 is further behind the gear 17 at the rear end of the second slide rail 152, and both the first slide rail 151 and the second slide rail 152 are inclined horizontally (of course, the first slide rail 151 may not be inclined horizontally, but only the second slide rail 152 is inclined), and at this time, the drawing of the first slide rail 151 and the second slide rail 152 is not smooth. However, due to the arrangement of the first reset section 18, the gear 17 of the first slide rail 151 enters the first reset section 18, and although the second slide rail 152 is inclined horizontally with respect to the second guide rail 142, the gear 17 of the second slide rail 152 can continue rolling, so that the second slide rail 152 is parallel to the second guide rail 142, and further, the closing of the storage drawer 13 is facilitated or the first slide rail 151 and the second slide rail 152 move synchronously again, so as to facilitate pushing and pulling.

It should be appreciated that when the gear 17 of the first sled 151 does not enter the first reset segment 18, the entry of the gear 17 of the second sled 152 is inconvenient for the horizontal movement of the first sled 151 due to the gear 17 of the first sled 151 engaging the rack portion 16 of the first track 141. However, according to the arrangement of the first reset segment 18 of the present utility model, after the gear 17 of the first slide rail 151 enters the first reset segment 18, since the gear 17 of the first slide rail 141 is not meshed with the rack portion 16, the first slide rail 151 can move in the horizontal direction easily, so that the gear 17 of the second slide rail 152 can roll easily, and the second slide rail 152 can move continuously so as to be parallel between the second slide rail 152 and the second slide rail 142.

In combination with the above, by the arrangement of the first reset section 18, when the second sliding rail 152 is inclined horizontally relative to the second guiding rail 142, the second sliding rail 152 can be parallel to the second guiding rail 142 again, so that the first sliding rail 151 and the second sliding rail 152 can move synchronously again, or the door body 131 of the storage drawer 13 can be closed conveniently.

Referring to fig. 9-12, in combination with the above-described embodiment related to the first slide rail 151 and the first guide rail 141, the gear 17 is disposed at the rear end of the first slide rail 151, the first reset section 18 is disposed at the rear end of the first guide rail 141, and when the storage drawer 13 seals the storage compartment 121, the gear 17 of the first slide rail 151 is located at the first reset section 18 at the rear end of the first guide rail 141.

By this arrangement, when the first sliding rail 151 is moved to a position where it cannot be moved further, if the second sliding rail 152 is not parallel, the second sliding rail 152 can be finally parallel to the second sliding rail 142 by the arrangement of the first reset section 18, and at this time, the second sliding rail 152 will also be moved to a position where it cannot be moved further. At this time, the door body 131 of the storage drawer 13 can be tightly attached to the liner 12, thereby achieving a good sealing effect.

In the drawings, it is shown that only one first reset segment 18 is provided on the rack portion 16 of the first rail 141, and the first reset segment 18 is provided at the rear end of the first rail 141. In other embodiments, the rack portion 16 of the first rail 141 is provided with a plurality of first reset sections 18, the plurality of first reset sections 18 being spaced apart along the length of the first rail 141.

For example, two first reset sections 18 are provided on the rack portion 16 of the first rail 141, and the two first reset sections 18 are provided at the middle and rear ends of the first rail 141, respectively, that is, one first reset section 18 is provided at the middle of the first rail 141 in fig. 10. At this time, if the second rail 142 is inclined when the storage drawer 13 is pushed or pulled for a part of the distance, the second rail 152 can be reset to be parallel by the first reset section 18 in the middle, and the storage drawer 13 can be pushed or pulled again smoothly. When the first sliding rail 151 moves to a position where the second sliding rail 152 cannot be pushed further, if the second sliding rail 152 is inclined, the second sliding rail 152 can be reset to be parallel by the first reset section 18 at the rear end, so that the closing seal of the door body 131 is facilitated. Of course, the number of reset sections and the set positions in another embodiment are not limited to the set manner in the above example.

It should be understood that the reset area in the middle is mainly used for enabling the first sliding rail 151 and the second sliding rail 152 to move synchronously again, and the first sliding rail 151 and the second sliding rail 152 at the rear end are used for correcting the deviation of the guiding rail so that the door body 131 can be closed smoothly.

In the above embodiments, the first reset area is set by the first rail 141, and in other embodiments, the second rail 142 is provided with a second reset section (not shown) without teeth, the gear 17 of the second rail 152 enters the second reset section, and when the first rail 151 is inclined horizontally with respect to the first rail 141, the gear 17 of the first rail 151 can roll continuously so that the first rail 151 is parallel to the first rail 141.

Specifically, the setting of the second reset section may refer to the setting of the first reset section 18, and will not be described again. By providing the second reset section on the second rail 142, the first rail 151 can be corrected when the first rail 151 is tilted with respect to the first rail 141. It should be appreciated that by providing the first reset segment 18 on the first rail 141 and the second reset segment on the second rail 142, the storage drawer 13 can achieve a better deviation correcting effect no matter being inclined towards that direction, and further the storage drawer 13 can move smoothly and can seal the storage compartment 121 well.

When the second reset sections are disposed on the second guide rail 142, the first reset section 18 of one first guide rail 141 and the second reset section of one second guide rail 142 form a pair of reset sections, and the first reset section 18 and the second reset section of the pair of reset sections are equal in length and are opposite to each other. For example, two first reset sections 18 are provided on the first rail 141, respectively at the middle and rear ends; two second reset sections are provided on the second rail 142, at the middle and rear ends, respectively. The first reset section 18 of the first guide rail 141 located at the middle and the second reset section of the second guide rail 142 located at the middle are equal in length and are opposite to each other, and the first reset section 18 of the first guide rail 141 located at the rear end and the second reset section of the second guide rail 142 located at the rear end are equal in length and are opposite to each other. Through the arrangement mode, on one hand, a better deviation rectifying effect is achieved, and on the other hand, the influence of the reset section on the moving stability of the storage drawer 13 can be reduced.

In some embodiments, referring to fig. 14, the rack portion 16 further includes an engagement section 1411 and a transition section 1412, the transition section 1412 being connected to the engagement section 1411 and the first reset section 18, respectively, the height of the teeth of the transition section 1412 being lower than the height of the teeth of the engagement section 1411 and higher than the height of the first reset section 18, and the gear 17 entering the first reset section 18 or the engagement section 1411 from the transition section 1412.

It will be appreciated that both the engagement section 1411 and the transition section 1412 are provided with teeth so that the gear 17 can engage both the engagement section 1411 and the transition section 1412, while the gear 17 is located in the first reset section 18, the gear 17 is not engaged and can slide over the first reset section 18. By providing the transition section 1412, the transition section has a low tooth height, and thus, the transition section can play a role in preventing the storage drawer 13 from being largely shaken when moving.

With continued reference to fig. 14, the transition section 1412 is provided with a plurality of teeth, the heights of which decrease in sequence in a direction approaching the transition section 1412. In fig. 14, it is shown that the transition section 1412 is provided with a first tooth 1412a and a second tooth 1412b arranged adjacently, the first tooth 1412a being lower in height than the teeth of the engagement section 1411, the second tooth 1412b being lower in height than the first tooth 1412a, but the second tooth 1412b being higher than the first reset section 18.
