[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0029] like Figures 1 to 5 As shown, an embodiment of the present application provides a sliding assembly, including a shell 1, a slider 2 and a driving assembly, a sliding groove 11 is formed on the shell 1, a part of the slider is slidably connected in the sliding groove, and the other part of the slider is arranged outside the sliding groove and has an abutment surface 23 intersecting with the extension direction of the sliding groove, and the driving assembly is transmission-connected to the slider.

[0030] When implementing it specifically, Figures 1 to 3 As shown, the slider 2 has a sliding portion 21 located in the slide slot and a pushing portion 22 protruding from the slide slot 11, and the sliding portion 21 is slidably connected to the slide slot 11. The pushing portion 22 has an abutting surface 23 intersecting with the extension direction of the slide slot 11. The driving component is in transmission connection with the slider 2, and the extension direction of the slide slot 11 is consistent with the translation direction of the storage box. When the driving component drives the slider 2 to move in the slide slot 11, the abutting surface 23 abuts against one side of the storage box, thereby pushing the storage box out of the slide slot.

[0031] The slider 2 may also include a sliding portion 21 slidably connected to the slide groove 11 and a pushing portion 22 (not shown in the figure) extending from one end of the slide groove 11 close to the storage box in the extension direction of the slide groove 11, that is, the pushing portion 22 and the sliding portion 21 are distributed along the extension direction of the slide groove.

[0032] The storage box of the car refrigerator is driven to open by the linear slide module (sliding assembly). The slider of the linear slide module is fixedly connected to the storage box, which means that the linear slide module needs to bear loads in three directions, and has high requirements on the structural strength of the slide rail of the linear slide module. If the slide rail is made of plastic, the service life of the slide rail will be shortened. If the slide rail is made of metal, the metal slide rail is not only easy to exchange heat between the inside and outside of the refrigerator, but also has high cost.

[0033] When the sliding assembly provided by the embodiment of the present application is in use, the chute 11 and the slider 2 of the housing 1 mainly bear the load in the direction of the storage box translation, and do not bear the load in the direction of the gravity of the storage box, nor the load in the third direction. The gravity direction of the storage box and the translation direction of the storage box are both perpendicular to the third direction. This reduces the requirements for the structural strength of the slider 2 and the chute 11 of the housing 1. The housing 1 and the slider 2 are both made of plastic, which reduces the cost. At the same time, it prevents the chute 11 and the slider 2 of the housing 1 from bearing unnecessary loads, thereby increasing the service life of the sliding assembly.

[0034] In a specific implementation, the shell 1 can be embedded in the side wall of the vehicle refrigerator, and the material of the slider 2 can be thermoplastic crystalline polymer POM.

[0035] In some embodiments, Figure 1 As shown, the bottom wall of the slide groove 11 is recessed along the depth direction of the slide groove 11 to form an oil storage groove 12, and the extension direction of the oil storage groove 12 is consistent with the extension direction of the slide groove 11. The oil storage groove 12 is filled with lubricating grease. There can be multiple oil storage grooves 12, and the multiple oil storage grooves 12 are distributed at intervals along the width direction of the slide groove 11. A lubricating oil film is formed on the bottom wall of the slide groove 11, and the sliding part 21 slides more smoothly in the slide groove 11.

[0036] In some further embodiments, Figure 1 As shown, a gap is provided between the side walls of the slide groove 11 on both sides along its width direction and the slider 2, so that the slider 2 will not rotate along its circumferential direction, and friction between the side walls of the slide groove 11 and the slider 2 can be avoided, so that the slider 2 can slide more smoothly in the slide groove 11.

[0037] In some embodiments, Figure 2 and Figure 3As shown, the driving assembly includes a screw rod 31 and a motor 32. A threaded hole is provided on the slider 2. The slider 2 is sleeved on the screw rod 31 through the threaded hole to form a screw nut pair with the screw rod 31. Part of the screw rod 31 is located in the slide groove 11 and extends along the length direction of the slide groove 11. One end of the screw rod 31 is connected to the motor 32.

[0038] For example, a brass sleeve 7 or a bearing is provided on the housing 1 and at one end of the slide slot 11 , and the other end of the screw rod 31 is connected to the housing 1 through the brass sleeve 7 or the bearing.

[0039] Considering the limited space in the car refrigerator, the motor 32 is located outside the car refrigerator, and the motor 32 and the screw rod 31 are both made of metal. The screw rod 31 is located inside the car refrigerator. The low temperature environment inside the car refrigerator and the high temperature environment outside the car refrigerator can easily exchange heat through the screw rod 31 and the motor 32, resulting in "cold leakage" of the car refrigerator.

[0040] Therefore, in some embodiments, the drive assembly further includes a coupling sleeve 4, such as Figure 3 As shown, the coupling sleeve 4 is inserted into the side wall of the vehicle refrigerator, the output shaft of the motor 32 is connected to the screw rod 31 through the coupling sleeve 4, the thermal conductivity of the coupling sleeve 4 is less than the thermal conductivity of the screw rod 31 and the motor 32, and the coupling sleeve 4 is made of plastic. In specific implementation, the material of the coupling sleeve 4 can be a composite material of PA6 and GF. Two blind holes extending along the axial direction of the screw rod 31 are formed on the coupling sleeve 4, and the two blind holes are not connected. The output shaft of the motor 32 is inserted in one blind hole, and the end of the screw rod 31 is inserted in the other blind hole. In other words, the coupling sleeve 4 with low thermal conductivity has a partition effect on the heat conduction of the motor 32 and the screw rod 31, and the heat exchange between the low temperature environment inside the vehicle refrigerator and the high temperature environment outside the vehicle refrigerator is effectively reduced, thereby improving the effective utilization of energy.

[0041] The embodiment of the present application further provides a storage box, which includes the above-mentioned sliding assembly, and an abutment portion (not shown in the figure) is formed on one side of the lower part of the storage box, and the abutment portion is used to abut against the abutment surface 23.

[0042] An embodiment of the present application also provides a vehicle refrigerator, which includes the above-mentioned storage box.

[0043] In some embodiments, Figures 3 to 5As shown, a part of the driving assembly is located outside the vehicle refrigerator, and another part of the driving assembly penetrates from the mounting hole on the vehicle refrigerator to the inside of the vehicle refrigerator. The part of the driving assembly located outside the vehicle refrigerator is covered with a mounting shell 33, and the mounting shell 33 is connected to the outer wall of the vehicle refrigerator. For example, the outer peripheral surface of the mounting shell 33 is formed with a connecting portion 51 along the radial extension of the screw rod 31, and the connecting portion 51 is connected to the outer wall of the vehicle refrigerator by a fastener. A connecting sleeve 5 is formed at a position corresponding to the mounting hole of the mounting shell 33, and the connecting sleeve 5 extends into the mounting hole. The connecting sleeve 5 is sleeved on the periphery of the coupling sleeve 4. The mounting shell 33 may include a first mounting shell and a second mounting shell connected to the connecting sleeve 5, and the first mounting shell and the second mounting shell are detachably connected to facilitate installation.

[0044] In some embodiments, Figure 3 As shown, the mounting hole is a conical hole, and a conical sealing sleeve 6 is provided between the mounting hole and the connecting sleeve 5, and the conical sealing sleeve 6 is sealed and connected to the mounting hole and the connecting sleeve 5 respectively. This prevents the gas or water vapor inside and outside the vehicle refrigerator from communicating through the mounting hole. The conical sealing sleeve 6 can be a sealing sleeve made of rubber material, which can absorb motor vibration. The sealing sleeve made of rubber material has a better effect in preventing heat exchange between the inside and outside of the refrigerator.

[0045] In specific implementation, the diameter of the mounting hole gradually decreases along the thickness direction of the side wall of the vehicle refrigerator from the outside to the inside. Firstly, other layered structures that cooperate with refrigeration are formed on the inner wall of the vehicle refrigerator, and it is not convenient to open a large opening on the inner wall. Secondly, when the connecting sleeve 5 and the conical sealing sleeve 6 are installed in the mounting hole, the connecting sleeve 5 and the conical sealing sleeve 6 are inserted into the mounting hole from the outside of the vehicle refrigerator. The mounting hole is arranged from large to small, which makes it easier to insert the connecting sleeve 5 and the conical sealing sleeve 6 into the mounting hole.

[0046] An embodiment of the present application also provides a vehicle, which includes the above-mentioned vehicle refrigerator.
