The drawer-type vehicle-mounted refrigerator is usually arranged in an armrest box between the main driver's seat and the co-driver's seat of the vehicle, and the drawer of the drawer-type vehicle-mounted refrigerator can be pulled out from the box body of the refrigerator for passengers to take and place articles. The above-mentioned drawer-type vehicle-mounted refrigerator has the following disadvantages: passengers located on both sides of the vehicle-mounted refrigerator far away from the vehicle-mounted refrigerator are inconvenient to operate when taking articles from the drawer. In order to further improve the comfort of passengers, the above-mentioned problem needs to be solved. CONTENT OF THE UTILITY MODEL

[0003] The embodiments of the present application provide a drawer and an assembly, and the embodiments of the present application also provide a vehicle-mounted refrigerator and a transport vehicle.

[0004] In a first aspect, the embodiments of the present application provide a drawer device, which is applied to a storage device having a cabinet, the cabinet is provided with a receiving cavity, and the drawer device comprises a drawer, a bottom plate, a rotating connection mechanism and a guide rail. The bottom plate is arranged at the bottom of the drawer. The rotating connection mechanism is connected between the drawer and the bottom plate, so that the drawer can rotate relative to the bottom plate about a specified axis. The guide rail is arranged on the bottom plate and is used to connect the cabinet, so that the bottom plate and the drawer are movably connected with the cabinet. The guide rail has an extension direction, and the bottom plate and the drawer can move relative to the cabinet based on the guide rail to enter or move out of the receiving cavity along the extension direction. The specified axis intersects with the extension direction.

[0005] Optionally, in some embodiments, the drawer device further comprises a rotating positioning mechanism, the rotating positioning mechanism comprises a positioning piece and a fixing assembly, the positioning piece is arranged on the drawer, the fixing assembly is arranged on the bottom plate, and the positioning piece movably engages with the fixing assembly. When the positioning piece engages with the fixing assembly, the fixing assembly limits the rotational freedom of the drawer through the positioning piece.

[0006] Optionally, in some embodiments, the positioning piece comprises a plurality of positioning portions, and the plurality of positioning portions are distributed along the rotating path of the drawer. The fixing assembly comprises a matching piece, and the matching piece movably engages with any one of the positioning portions. When the matching piece engages with the positioning portion, the matching piece limits the rotational freedom of the drawer through the positioning piece.

[0007] Optionally, in some embodiments, the fixing component further includes a fixing seat and an elastic member. The fixing seat is fixedly disposed on the base plate, the mating member is movably disposed on the fixing seat, and the elastic member is disposed between the mating member and the fixing seat. The positioning part is provided with a retaining groove, and the elastic member elastically abuts against the mating member so that the mating member and the retaining groove can be movably nested and mated.

[0008] Optionally, in some embodiments, the positioning member further includes two limit limiting parts, which are located at both ends of the rotation path of the drawer, and the limit limiting parts are used to contact the fixing component to limit the extreme positions of the drawer rotation.

[0009] Optionally, in some embodiments, a support is provided on the side of the drawer facing the bottom plate, and the support contacts the bottom plate.

[0010] Optionally, in some embodiments, the support includes a rib extending along an arc, the center of which coincides with a designated axis.

[0011] Optionally, in some embodiments, the rotating connection mechanism includes a bearing connected between the base plate and the drawer, with the central axis of the bearing coinciding with a designated axis.

[0012] Secondly, this application also provides a vehicle refrigerator, which includes a cabinet and the above-mentioned drawer device. The cabinet is provided with an installation cavity, and the drawer is movably disposed in the installation cavity. The guide rail of the drawer device is connected to the cabinet so that the bottom plate and the drawer can enter or exit the installation cavity along the extension direction of the guide rail.

[0013] Thirdly, this application also provides a transport vehicle, which includes a body and the aforementioned vehicle-mounted refrigerator. The body is provided with a driver's cabin, and the vehicle-mounted refrigerator is installed inside the driver's cabin.

[0014] The drawer device provided in this application embodiment, due to its configuration of a drawer, a base plate, a rotating connecting mechanism, and guide rails, allows the drawer and base plate to be simultaneously moved out of the cabinet's receiving cavity along the guide rails during use. Then, the rotating connecting mechanism causes the drawer to rotate relative to the base plate around a designated axis, enabling the drawer to rotate to different positions to facilitate users located at different points on the drawer device to retrieve items from inside. Specifically, in the case of a car refrigerator using the aforementioned drawer device, after the drawer is completely removed from the refrigerator's mounting cavity, the drawer can rotate relative to the base plate around a designated axis via the rotating connecting mechanism, facilitating passengers on either side of the car refrigerator to retrieve items from the drawer. In summary, the aforementioned drawer device offers the beneficial effects of allowing the drawer to rotate after being pulled out, making it convenient for users to retrieve items from inside the drawer.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0025] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or state relationship based on the orientation or state relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0026] Furthermore, in addition to indicating location or state relationships, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0027] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] Furthermore, unless otherwise explicitly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0030] Please see Figure 1 This application provides a drawer device 100, which is applied to a storage device with a cabinet body, the cabinet body having a receiving cavity. The drawer device 100 includes a drawer 10, a base plate 11, and a rotating connection mechanism 12 (see...). Figure 3 ) and guide rail 13. Specifically, the storage device can be any device with storage function, such as a table, cabinet, or car refrigerator 200. In this embodiment, the storage device is the car refrigerator 200 (see Figure 2 and Figure 3 The specific structure of the drawer device 100 will be explained using an example. The vehicle refrigerator 200 includes a cabinet 20 and the aforementioned drawer device 100. The cabinet 20 has a mounting cavity 201. The cabinet of the storage device is the cabinet 20 of the vehicle refrigerator 200, and the receiving cavity of the cabinet is the mounting cavity 201 of the cabinet 20. The drawer 10 of the drawer device 100 is movably disposed within the mounting cavity 201. The guide rail 13 of the drawer device 100 is connected to the cabinet 20, so that the bottom plate 11 and the drawer 10 can enter or exit the mounting cavity 201 along the extension direction X of the guide rail 13. It should be noted that the extension direction X of the guide rail 13 is approximately the same as the length direction of the guide rail 13. The movement of the bottom plate 11 and the drawer 10 along the extension direction X of the guide rail 13 can be understood as the movement of the bottom plate 11 and the drawer 10 along the length direction of the guide rail 13.

[0031] The following is a detailed description of the various components of the drawer assembly 100.

[0032] Please see Figure 1 , Figure 2 and Figure 3Drawer 10 is the main structure of drawer assembly 100 for accommodating items, and its shape is generally cubic. A base plate 11 is disposed at the bottom of drawer 10. The base plate 11 is generally flat and is used to connect drawer 10 to guide rail 13. A rotating connection mechanism 12 is connected between drawer 10 and base plate 11, allowing drawer 10 to rotate relative to base plate 11 about a designated axis O. Guide rail 13 is disposed on base plate 11 and is used to connect to cabinet (i.e., the cabinet 20 of vehicle refrigerator 200), allowing base plate 11 and drawer 10 to be movably connected to cabinet. Guide rail 13 has an extending direction X, and base plate 11 and drawer 10 can move relative to cabinet based on guide rail 13 to enter or exit the receiving cavity (i.e., the mounting cavity 201 of vehicle refrigerator 200) along the extending direction X. Designated axis O (reference) Figure 4 As a specific example, in this embodiment, the plane containing the base plate 11 is substantially parallel to or coincides with the extension direction X, and the designated axis O can be perpendicular to the base plate 11. Therefore, the designated axis O is substantially perpendicular to the extension direction X, and the drawer 10 can rotate around the designated axis O on the surface of the base plate 11. In other embodiments, the designated axis O may also intersect the extension direction X but not be perpendicular to it.

[0033] The drawer device 100 provided in this application embodiment includes a drawer 10, a base plate 11, a rotating connecting mechanism 12, and a guide rail 13. During use, the drawer 10 and the base plate 11 can be simultaneously moved out of the cabinet's receiving cavity (i.e., the mounting cavity 201 of the cabinet 20) along the guide rail 13. Then, the rotating connecting mechanism 12 causes the drawer 10 to rotate relative to the base plate 11 around a designated axis O, allowing the drawer 10 to rotate to different positions to facilitate users located at different positions within the drawer device 100 to retrieve items from the drawer 10. Specifically, in the use of the vehicle refrigerator 200 equipped with the above-mentioned drawer device 100, after the drawer 10 has been completely removed from the mounting cavity 201 of the vehicle refrigerator 200's cabinet 20, the drawer 10 can rotate relative to the base plate 11 around a designated axis via the rotating connecting mechanism 12, facilitating passengers located on both sides of the vehicle refrigerator 200 to retrieve items from the drawer 10. In summary, the drawer device 100 described above has the beneficial effect of allowing the drawer 10 to rotate after being pulled out, making it convenient for users to take out items from the drawer 10.

[0034] Please see Figure 4 , Figure 5 and Figure 6In some embodiments, the drawer device 100 further includes a rotation positioning mechanism 14, which is disposed between the drawer 10 and the base plate 11. The rotation positioning mechanism 14 is used to achieve rotational positioning of the drawer 10 to restrict the rotational freedom of the drawer 10. Specifically, the rotation positioning mechanism 14 includes a positioning element 141 and a fixing component 142. The positioning element 141 is disposed on the drawer 10, and the fixing component 142 is disposed on the base plate 11. The positioning element 141 is movably engaged with the fixing component 142 to achieve rotational positioning of the drawer 10. It should be noted that "the positioning element 141 is movably engaged with the fixing component 142" means that the positioning element 141 has a state of engagement with the fixing component 142 and a state of non-engagement with the fixing component 142 during the rotation of the drawer 10. When the positioning element 141 and the fixing component 142 are engaged, the fixing component 142 restricts the rotational freedom of the drawer 10 through the positioning element 141, that is, the fixing component 142 restricts the free rotation of the drawer 10 through the positioning component.

[0035] With the above configuration, during the rotation of the positioning component 141 driven by the drawer 10, when the positioning component 141 and the fixing component 142 are in a locked engagement, the positioning component 141 is locked by the fixing component 142 and cannot rotate freely. Therefore, the drawer 10 cannot rotate freely either. At this time, the position of the drawer 10 remains basically stable, making it convenient for users to reliably take items out of the drawer 10 or put items into the drawer 10. When the positioning component 141 and the fixing component 142 are not in a locked engagement, the positioning component 141 can rotate freely with the drawer 10 relative to the fixing component 142. Users can rotate the drawer 10 to different angles as needed, so that people at different positions outside the drawer 10 can take items out of the drawer 10 or put items into the drawer 10.

[0036] Please see Figure 4 , Figure 5 and Figure 6In some embodiments, the positioning member 141 includes a plurality of positioning portions 1411, which are the main components of the positioning member 141 that achieve engaging engagement with the fixing component 142. In this embodiment, the plurality of positioning portions 1411 are distributed at intervals along the rotation path of the drawer 10, and the positioning portions 1411 can be of any shape, such as a block structure or a rod structure. The fixing component 142 includes a mating member 1421, which is movably engaged with any one of the positioning portions 1411. The mating member 1421 can be of any shape, such as a block structure or a rod structure. It should be noted that "the mating member 1421 is movably engaged with any one of the positioning portions 1411" means that during the rotation of the positioning member 141 with the drawer 10, there is a state in which any one of the positioning portions 1411 is engaged with the mating member 1421, and there is also a state in which all the positioning portions 1411 are not engaged with the mating member 1421. When the mating part 1421 is engaged with (any one) the positioning part 1411, the mating part 1421 restricts the rotational freedom of the drawer 10 through the positioning part 141.

[0037] With the above configuration, during the rotation of the drawer 10 and the positioning member 141, when any one of the positioning parts 1411 and the mating part 1421 is in a locked engagement, the positioning member 141 is held by the fixing component 142 and cannot rotate freely. Therefore, the drawer 10 cannot rotate freely either. At this time, the position of the drawer 10 remains basically stable, making it convenient for the user to reliably take out items from the drawer 10 or put items into the drawer 10. When all the positioning parts 1411 and the mating part 1421 are not in a locked engagement, the positioning member 141 can rotate freely with the drawer 10 relative to the fixing component 142. The user can rotate the drawer 10 to different angles as needed, so that people at different positions outside the drawer 10 can take out items from the drawer 10 or put items into the drawer 10.

[0038] In some embodiments, the positioning member 141 further includes a body portion 1414 connected to the positioning part 1411 (see Figure 6The main body 1414 is the main structure of the positioning member 141. The main body 1414 is connected to the side wall of the drawer 10 facing the bottom plate 11. As a specific example, in this embodiment, the main body 1414 is approximately semi-circular, and the main body 1414 and the drawer 10 are connected by a locking block, with the designated axis O passing through the center of the main body 1414. The positioning part 1411 is a protrusion provided on the side of the main body 1414 away from the center of the main body 1414. There are three positioning parts 1411, which are located at both ends and the middle position of the main body 1414, respectively. When the drawer 10 enters or exits the cabinet (i.e., the cabinet 20 of the vehicle refrigerator 200) along the extension direction X, the middle positioning part 1411 engages with the fixing component 142 to ensure that the drawer 10 can move stably along the extension direction X. In other embodiments, the body part 1414 can also be any shape such as a ring or a disc. The body part 1414 and the drawer 10 can also be connected by fasteners such as screws / bolts. The positioning parts 1411 can also be provided in any number of times, such as two, four, or five. The specific positions of the multiple positioning parts 1411 can also be set according to the usage requirements. In this embodiment, there are no limitations on the specific shape of the body part 1414, the specific connection method between the body part 1414 and the drawer 10, the number of positioning parts 1411, and their setting positions.

[0039] Please see Figure 4 , Figure 5 and Figure 6In some embodiments, the fixing assembly 142 further includes a fixing seat 1422 and an elastic member 1423. The fixing seat 1422 is the main component for connecting and installing the fixing assembly 142 to the base plate 11, and the elastic member 1423 is an elastic member used to engage the mating part 1421 with the positioning part 1411. The fixing seat 1422 is fixedly disposed on the base plate 11, the mating part 1421 is movably disposed on the fixing seat 1422, that is, the mating part 1421 can move relative to the fixing seat 1422, and the elastic member 1423 is disposed between the mating part 1421 and the fixing seat 1422. As a specific example, in this embodiment, the fixing seat 1422 is generally rectangular, and the elastic member 1423 is a spring. In other embodiments, the fixing seat 1422 can also be any shape such as a cube or cylinder, and the elastic member 1423 can also be any elastic component such as a spring sheet or an elastic rubber component. The positioning part 1411 is provided with a retaining groove 1412, and the elastic member 1423 elastically abuts against the mating member 1421 so that the mating member 1421 and the retaining groove 1412 can be movably nested together. It should be noted that the above-mentioned "matting member 1421 and retaining groove 1412 can be movably nested together" means that under the elastic abutment of the elastic member 1423, the mating member 1421 can abut against the inner wall of the retaining groove 1412. At this time, the mating member 1421 and the positioning part 1411 are in a locked state, and the mating member 1421 will restrict the rotational freedom of the drawer 10. When an external force causes the mating member 1421 to overcome the elastic force of the elastic member 1423 and move out of the retaining groove 1412, the mating member 1421 and the positioning part 1411 are in a non-locked state. At this time, the mating member 1421 loses its positioning function for the drawer 10, and the drawer 10 can rotate freely to meet the user's usage needs.

[0040] With the above settings, during the rotation of drawer 10, when drawer 10 rotates to the position where the mating part 1421 engages with the retaining groove 1412 of any positioning part 1411, the rotational freedom of drawer 10 is restricted by the mating part 1421, and drawer 10 is in a relatively stable state and cannot rotate freely. At this time, the position of drawer 10 remains basically stable, making it convenient for users to reliably take items out of drawer 10 or put items into drawer 10. Only when the mating part 1421 overcomes the elastic force of elastic member 1423 under the action of external force and moves out of retaining groove 1412, the mating part 1421 loses its retaining effect on positioning part 1411, and drawer 10 can rotate freely again to meet the user's needs.

[0041] In some embodiments, the fixing base 1422 is provided with a limiting groove 1424, the mating member 1421 is movably inserted into the limiting groove 1424, one end of the elastic member 1423 is connected to the mating member 1421, and the other end is connected to the inner wall of the limiting groove 1424. At any given time, at least a portion of the mating member 1421 is always located within the limiting groove 1424 and in contact with the inner wall of the limiting groove 1424, and at least a portion of the mating member 1421 is also located outside the limiting groove 1424. With the above configuration, when the mating part 1421 and the positioning part 1411 are in a locked engagement state, at least a portion of the structure of the part of the mating part 1421 outside the limiting groove 1424 is inserted into the locking groove 1412. At this time, when the drawer 10 is subjected to force and has a tendency to continue rotating, the positioning part 1411 and the mating part 1421 are locked together, and the mating part 1421 and the limiting groove 1424 are locked together, thus restricting the rotational freedom of the drawer 10, so as to achieve the positioning effect of the drawer 10.

[0042] In some embodiments, the inner sidewall of the retaining groove 1412 has a first guide surface 1415 and a second guide surface 1416. The side of the first guide surface 1415 near the body portion 1414 coincides with the side of the second guide surface 1416 near the body portion 1414, and the side of the first guide surface 1415 away from the body portion 1414 is separated from the side of the second guide surface 1416 away from the body portion 1414, so that the retaining groove 1412 is generally a triangular groove. The end of the mating member 1421 away from the elastic member 1423 is provided with a retaining block 1425 adapted to the retaining groove 1412. The retaining block 1425 has a first mating surface 1426 and a second mating surface 1427. The side of the first mating surface 1426 away from the elastic member 1423 coincides with the side of the second mating surface 1427 away from the elastic member 1423, and the side of the first mating surface 1426 near the elastic member 1423 is separated from the side of the second mating surface 1427 near the elastic member 1423, so that the retaining block 1425 is approximately a triangular protrusion. When the mating member 1421 and the retaining groove 1412 are in a retaining engagement state, the retaining block 1425 is inserted into the retaining groove 1412, the first mating surface 1426 is in contact with the first guide surface 1415, and the second mating surface 1427 is in contact with the second guide surface 1416.

[0043] With the above configuration, when the mating part 1421 and the retaining groove 1412 are in a retaining engagement state, when the drawer 10 is subjected to a sufficiently large external force along its own rotation path, the retaining block 1425 can slide out of the retaining groove 1412 along the first guide surface 1415 or the second guide surface 1416, so that the mating part 1421 loses its retaining and positioning effect on the positioning part 1411, thereby restoring the drawer 10 to a state where it can rotate freely, making it convenient for the user to operate.

[0044] Please see Figure 4 ,Figure 5 and Figure 6 In some embodiments, the positioning member 141 further includes two limit limiting portions 1413, which are located at both ends of the rotation path of the drawer 10. The limit limiting portions 1413 are used to contact the fixing component 142 to limit the extreme positions of the drawer 10's rotation. As a specific example, in this embodiment, the limit limiting portion 1413 is a block-shaped structure provided at the end of the body portion 1414, and the limit limiting portion 1413 is specifically connected to the positioning portion 1411 provided at the end of the body portion 1414. The limit limiting portion 1413 protrudes in a direction away from the body portion 1414 relative to the positioning portion 1411. In this embodiment, the two limit limiting portions 1413 limit the rotation range of the drawer 10 to 180°. Taking the middle position (i.e., the positioning portion 1411 located in the middle) as the initial position, the drawer 10 can rotate 90° clockwise or 90° counterclockwise. In other embodiments, the limit limiting part 1413 may also be directly disposed on the side of the main body part 1414 away from the center of the main body part 1414. The two limit limiting parts 1413 may also be disposed at any position outside the end of the main body part 1414, as long as all the positioning parts 1411 are located between the two limit limiting parts 1413. In this embodiment, the specific installation position of the limit limiting part 1413 is not limited.

[0045] With the above settings, during the rotation of the drawer 10, after the limit limiting part 1413 comes into contact with the mating part 1421, the limit limiting part 1413 will lock with the mating part 1421 to prevent the drawer 10 from continuing to rotate. Therefore, the two limit limiting parts 1413 can limit the two extreme positions of the drawer 10 rotation, thereby limiting the rotation range or rotation angle of the drawer 10.

[0046] Please see Figure 5 In some implementations, a support member 101 is provided on the side of drawer 10 facing the base plate 11, and the support member 101 contacts the base plate 11. With the above arrangement, during the rotation of drawer 10, the support member 101 can abut against the surface of the base plate 11 facing drawer 10 to support drawer 10, which can make the rotation of drawer 10 more stable and reliable, and improve the stability of drawer 10 rotation.

[0047] In some embodiments, the support member 101 includes a raised rib extending along an arc, the center of which coincides with a designated axis O. With this arrangement, the extending direction of the support member 101 is almost the same as the rotation direction of the drawer 10, thus reducing the frictional resistance from the base plate 11 experienced by the support member 101 during drawer 10 rotation, thereby reducing the obstructive effect of the support member 101 on drawer 10 rotation and improving the smoothness of drawer 10 rotation.

[0048] In some embodiments, multiple support members 101 are provided, and the multiple support members 101 are arranged concentrically at intervals. With the above arrangement, the support effect of the support members 101 on the drawer 10 can be further improved, thereby further improving the stability and reliability of the rotation of the drawer 10.

[0049] In some embodiments, a plurality of support members 111 are provided on the side of the base plate 11 facing the drawer 10. The support members 111 contact the drawer 10 and include a rib extending along an arc, the center of which coincides with a designated axis O. The plurality of support members 111 are concentrically spaced. With the above arrangement, during the rotation of the drawer 10, the support members 111 can abut against the surface of the drawer 10 facing the base plate 11 to support the drawer 10, making the rotation of the drawer 10 more stable and reliable, improving the stability of the drawer 10 rotation, and reducing the frictional resistance from the drawer 10 to the support members 111 during the rotation of the drawer 10, thereby reducing the obstructive effect of the support members 111 on the rotation of the drawer 10 and improving the smoothness of the rotation of the drawer 10.

[0050] Please see Figure 3 and Figure 4 In some embodiments, the rotating connection mechanism 12 includes a bearing 121 connected between the base plate 11 and the drawer 10, with the central axis of the bearing 121 coinciding with a designated axis O. Specifically, the outer ring of the bearing 121 is fixedly connected to the base plate 11, and the inner ring of the bearing 121 is fixedly connected to the side wall of the drawer 10 facing the base plate 11. Through this arrangement, the bearing 121 achieves a rotating connection between the drawer 10 and the base plate 11, and the base plate 11 can drive the drawer 10 to slide along the guide rail 13. In other embodiments, the rotating connection mechanism 12 can also be any type of rotating component, such as a rotating shaft or coupling, connected between the base plate 11 and the drawer 10 to achieve a rotating connection between the drawer 10 and the base plate 11.

[0051] Please see Figure 7 This application also provides a transport vehicle 300, which refers to a tool used for transporting passengers and goods, such as a vehicle, a manned aircraft, or a ship. In this application, the transport vehicle 300 can be a vehicle, which refers to a means of transportation driven or towed by a power device for carrying people or transporting goods, including but not limited to cars, suburban utility vehicles (SUVs), multi-purpose vehicles (MPVs), buses, trucks, etc. In the following description, the transport vehicle 300 is used as an example.

[0052] In this embodiment, the transport vehicle 300 includes a body 30 and the aforementioned vehicle-mounted refrigerator 200. Specifically, when the transport vehicle 300 is a vehicle, the body 30 can be a vehicle body, which serves to fix and house the vehicle-mounted refrigerator 200. The body 30 may include a driver's cab 301 for the driver to sit in, allowing the driver to control the transport vehicle 300 through a control system (e.g., center console, drive system, braking system, etc.) located within the driver's cab 301. The vehicle-mounted refrigerator 200 is located within the driver's cab 301 to facilitate easy access for the driver or passengers to items placed inside.

[0053] Please see Figure 2 , Figure 3 and Figure 7 With the above-mentioned arrangement, when passengers or drivers in the transport vehicle 300 take out items from the vehicle refrigerator 200, they can first pull the drawer 10 out of the receiving cavity, and then rotate the drawer 10 to the appropriate position as needed. Therefore, the transport vehicle 300 has the beneficial effect of facilitating the retrieval of items from the vehicle refrigerator 200 by the personnel in the cabin.
