[0002] See also Figure 7 The existing vehicle refrigerator includes an inner tank and a drawer that is movable in the inner tank. The inner tank and the drawer are both provided with sliding assemblies on the left and right sides. The sliding assembly includes a fixed rail fixed on the inner side of the inner tank and a movable rail on the outer side of the drawer. The movable rail and the fixed rail slide in cooperation so that the drawer is reciprocated and pulled in the inner tank. Since the sliding assembly is arranged between the inner side of the inner tank and the outer side of the drawer, the horizontal size of the refrigerator is large, and the refrigerator occupies a large space. Moreover, when the vehicle is driving on a bumpy road, the sliding assembly is arranged between the inner side of the inner tank and the outer side of the drawer, the bottom of the drawer is suspended, the seismic resistance is poor, and the refrigerator drawer is easy to slide in the inner tank.

[0003] In addition, some existing car refrigerators use a fully automatic door opening method, adding motors and some transmission mechanisms, etc., so it is necessary to consider the installation space, so it is necessary to design a reasonable car refrigerator. Summary of the invention

[0004] The purpose of the present invention is to provide a sliding structure and a new energy vehicle refrigerator. An installation cavity for installing a sliding assembly is formed below the bottom of the drawer and between the upper and lower parts of the bracket. The sliding assembly is installed on the installation cavity with an inclined limiter. The bottom of the refrigerator drawer is no longer suspended in the air. When the vehicle is driving on a bumpy road, the anti-vibration ability is good. The sliding assembly is installed in the installation cavity with an inclined limiter. The refrigerator drawer is stably arranged in the inner tank. When the vehicle is driving on a bumpy road, it is not easy to slide in the inner tank, and the durability is good.

[0005] The object of the present invention is achieved in that: 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 upper and lower parts of the bracket, and the sliding assembly is installed in the installation cavity in an inclined limit manner.

[0006] Inclined limit plates are provided on both sides of the drawer bottom. The inclined limit plates on both sides of the drawer bottom are trumpet-shaped and cover the bracket together with the drawer bottom. An installation cavity is formed between the inclined limit plates on both sides of the drawer bottom and the bracket above and below.

[0007] The inclined limit plates on both sides of the bottom of the drawer are horn-shaped, and the inclined limit of the sliding assembly is installed between the limit plate and the bracket, so that the refrigerator drawer is more stable during the sliding process. 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 tank do not need to be set too large. Therefore, the drawer is not prone to left and right shaking during the sliding process and after the drawer is installed in the inner tank, and the horizontal size of the refrigerator is effectively reduced, saving the horizontal installation space of the refrigerator.

[0008] A connecting plate for increasing the load-bearing strength of the drawer is provided between the limiting plates on both sides of the bottom of the drawer, and the connecting plate is connected to the limiting plates. The connecting plate is beneficial to increasing the load-bearing capacity of the bottom of the drawer and increasing the mechanical strength of the drawer.

[0009] An inclined limiting plate is provided at the bottom of the drawer, and the bracket includes an extension plate, which is arranged to extend obliquely along the outer side of the bracket and forms a support portion for increasing the mechanical strength of the bracket; The limit plate and the extension plate have the same inclination direction, the sliding assembly is inclined and limited between the limit plate and the extension plate, and the upper and lower limits of the sliding assembly are between the limit plate and the extension plate; The sliding assembly is limited up and down by the limit plate and the extension plate, so when the vehicle is driving on a bumpy road, the drawer is not easy to slide longitudinally in the inner tank.

[0010] The bracket is in an M shape, the bracket is in an M shape, the bracket has high mechanical strength, and a sliding assembly is provided between the inclined limit plates on both sides of the bottom of the drawer and the M-shaped bracket to ensure the smooth sliding of the refrigerator drawer.

[0011] An inner liner is provided on the outside of the drawer, and the inner liner covers the drawer and the bracket. The bracket is supported on the bottom wall of the inner cavity of the inner liner. The inner side of the inner liner covers the opening on one side of the installation cavity.

[0012] An assembly cavity for installing a drive belt assembly is also formed between the bottom of the drawer and the bracket. The drive belt assembly includes a drive belt fixedly connected to the drawer. When the drive belt is running, it drives the drawer to move in the direction of the sliding assembly. The space between the bottom of the drawer and the upper and lower parts of the bracket is effectively utilized, and the space is used to install the transmission belt assembly, thereby saving the installation space of the transmission assembly and making the refrigerator drawer structure more compact.

[0013] The transmission belt assembly includes a driving wheel and a driven wheel, the driven wheel is rotatably set on the bracket, the drawer and the bracket are set in the inner cavity, a front and rear position adjustment structure is provided between the bottom wall of the inner cavity of the inner tank and the bracket, the bracket is supported on the bottom wall of the inner cavity of the inner tank, and the front and rear position of the bracket on the bottom wall of the inner cavity is adjusted by the front and rear position adjustment structure to adjust the front and rear spacing between the driven wheel and the driving wheel, thereby adjusting the tightness of the transmission belt.

[0014] The front and rear position adjustment structure eliminates the existing setting method of using a tensioning wheel for the transmission belt, which is simple to adjust and effectively simplifies the transmission belt assembly, further saving installation space. In addition, the refrigerator's fully automatic door opening and closing uses a transmission belt that does not require lubricating oil, avoiding the high viscosity of the lubricating oil in a low temperature environment and avoiding high transmission friction. Therefore, it effectively replaces the existing screw and nut, as well as the gear rack structure that requires lubricating oil transmission.

[0015] A clamping assembly for clamping the transmission belt is provided under the bottom of the drawer. The clamping assembly includes a pressure block and a locking block. The pressure block and the locking block clamp the transmission belt. When the pressure block and the locking block are locked and connected, the clamping assembly and the transmission belt are in a locked and fixed state, and the drawer is fixedly connected to the transmission belt through the clamping assembly.

[0016] The upper and lower intervals between the drawer bottom and the bracket can form a space for the pressing block and the locking block to be locked and fixedly connected (which can be understood as a convenient place for installing screws).

[0017] An engaging anti-skid portion is provided between the clamping assembly and the transmission belt, and the clamping assembly is engaged and connected with the transmission belt through the engaging anti-skid portion, so that when the transmission belt is running, the drawer moves synchronously with the transmission belt.

[0018] The bite anti-skid portion is provided to prevent the drawer from following the movement of the transmission belt when the transmission belt is running.

[0019] The clamping assembly is provided with left and right limit parts. When the clamping assembly clamps the transmission belt, the transmission belt is limited on the clamping assembly through the left and right limit parts. The transmission belt can only run along the left and right limit parts to prevent the drawer and the transmission belt from swinging.

[0020] A new energy vehicle refrigerator comprises a box body and the above-mentioned sliding structure.

[0021] The beneficial effects of the present invention are as follows: An installation cavity for installing the sliding assembly is formed between the bottom of the drawer and the upper and lower parts of the bracket.
