The refrigerator drawer is stably arranged in the inner container. When the vehicle is driving on a bumpy road section, it is not easy to slide in the inner container, and the durability is good.

[0005] The purpose of the utility model is realized as follows:

[0006] A sliding structure includes a sliding assembly arranged between a drawer and a bracket. The bracket is arranged below the bottom of the drawer, and an installation cavity for installing the sliding assembly is formed between the bottom of the drawer and the bracket up and down. The sliding assembly is installed on the installation cavity in an inclined limiting manner.

[0007] Inclined limiting plates are arranged on both sides of the bottom of the drawer. The inclined limiting plates on both sides of the bottom of the drawer are in a horn shape and jointly cover the bracket with the bottom of the drawer. An installation cavity is formed between the inclined limiting plates on both sides of the bottom of the drawer and the bracket up and down.

[0008] The limiting plates inclined on both sides at the bottom of the drawer are trumpet-shaped. The sliding assembly is installed in a tilted and limited manner between the limiting plates and the bracket, making the refrigerator drawer slide more smoothly. Since the sliding assembly is arranged between the bracket and the bottom of the drawer, the left and right gaps between the drawer and the inner liner do not need to be set too large. Therefore, during the sliding process of the drawer and after the drawer is installed in the inner liner, the drawer is not prone to left and right shaking, and the horizontal size of the refrigerator is effectively reduced, saving the installation space in the horizontal direction of the refrigerator.

[0009] A connecting plate for increasing the load-bearing strength of the drawer is provided between the limiting plates on both sides at the bottom of the drawer, and the connecting plate is connected to the limiting plate. The connecting plate is beneficial to increasing the bottom load-bearing capacity of the drawer and enhancing the mechanical strength of the drawer.

[0010] The bottom of the drawer is provided with inclined limiting plates, and the bracket includes an extension plate which extends in an inclined manner along the outside of the bracket and forms a supporting part for increasing the mechanical strength of the bracket;

[0011] The limiting plates and the extension plate have the same inclined direction, and the sliding assembly is installed in a tilted and limited manner between the limiting plates and the extension plate, and the sliding assembly is limited up and down between the limiting plates and the extension plate;

[0012] The sliding assembly is limited up and down by the limiting plates and the extension plate. When the vehicle is driving on a bumpy road section, the drawer is not prone to longitudinally slide in the inner liner.

[0013] The bracket is in an M shape. The bracket is in an M shape with high mechanical strength. A sliding assembly is provided between the inclined limiting plates on both sides at the bottom of the drawer and the M-shaped bracket to ensure the smooth sliding of the refrigerator drawer.

[0018] The front and rear position adjustment structure cancels the existing setting method of using a tension pulley for the drive belt, with simple adjustment, effectively simplifies the drive belt assembly, further saves the installation space. In addition, the full-automatic opening and closing door of the refrigerator uses a drive belt, which does not require lubricating oil, avoiding the large viscosity of the lubricating oil in a low-temperature environment and large transmission friction. Therefore, it effectively replaces the existing screw and nut, as well as the structure of the gear rack that requires lubricating oil for transmission.

[0019] A clamping assembly for clamping the drive belt is provided below the bottom of the drawer. The clamping assembly includes a pressing block and a locking block. The pressing block and the locking block clamp the drive belt. When the pressing block and the locking block are locked and connected, the clamping assembly and the drive belt are in a locked and fixed state, and the drawer is fixedly connected to the drive belt through the clamping assembly.

[0020] A space (which can be understood as a place convenient for installing screws) for the locking and fixed connection of the pressing block and the locking block can be formed by the upper and lower spacing of the bottom of the drawer and the bracket.

[0021] An engaging and anti-slip portion is provided between the clamping assembly and the drive belt. The clamping assembly is engaged and connected to the drive belt through the engaging and anti-slip portion, so that when the drive belt runs, the drawer moves synchronously with the drive belt.

[0022] By providing the engaging and anti-slip portion, it is prevented that the drawer cannot move with the drive belt when the drive belt runs.

[0023] Left and right limiting portions are provided on the clamping assembly. When the clamping assembly clamps the drive belt, the drive belt is limited on the clamping assembly through the left and right limiting portions.
