All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0021] As Figures 1-4 shown, in some illustrative embodiments, a vehicle-mounted refrigerator installation device for heavy commercial vehicles is provided, specifically an installation device for an original factory vehicle-mounted refrigerator, including: a refrigerator support mechanism, a refrigerator panel, and a locking mechanism.

[0022] The refrigerator support mechanism is used to load and fix the vehicle-mounted refrigerator body 1 inside the vehicle, and it is composed of a front tray bracket 8 and side tray brackets 3 arranged at both ends of the front tray bracket 8; the front tray bracket 8 provides front support for the refrigerator, and the side tray brackets 3 are used for lateral support of the refrigerator to ensure the stability of the refrigerator during vehicle driving. A refrigerator tray 33 is provided at the bottom of the side tray bracket 3, and the refrigerator tray 33 is a flat plate for directly supporting the bottom of the vehicle-mounted refrigerator body 1.

[0023] Both the refrigerator support plate 33 and the front tray bracket 8 are provided with refrigerator mounting screw holes 38. Correspondingly, the bottom and the front of the in-vehicle refrigerator body 1 are provided with positioning mounting holes, and internal nuts are provided in the holes. The refrigerator support mechanism is connected to the in-vehicle refrigerator body 1 through 12 bolts on the bottom surface and 10 bolts on the front surface. The refrigerator support mechanism can realize the installation and fixation of the in-vehicle refrigerator body 1, ensuring that the refrigerator remains stable during vehicle driving and will not shift or fall off due to the movement of the vehicle. It is both practical and safe, and is suitable for vehicles that need to drive for a long time, such as heavy commercial vehicles.

[0024] The outer side surface of the side tray bracket 3 is provided with a three-stage slide rail 2 connected to the sleeper bracket 11. The lower part of the sleeper bracket 11 is fixed to the cab body through bolts, and the upper part is used to support the sleeper assembly. The sleeper bracket 11 and the side tray bracket 3 are connected through the three-stage slide rail 2. The three-stage slide rail 2 is a sliding track system with three levels or stages. In this embodiment, the guiding part of the three-stage slide rail 2 is arranged on the sleeper bracket 11, and the slider part is arranged on the refrigerator support mechanism. The sleeper bracket 11 is a fixed part, and the in-vehicle refrigerator body 1 and the refrigerator support mechanism are moving parts. With the help of the three-stage slide rail 2, the function of pulling out and pushing back the refrigerator can be realized. The inner side surface of the side tray bracket 3 is provided with a felt 14, and the felt 14 can reduce the noise during driving and at the same time protect the in-vehicle refrigerator body 1 from damage.

[0025] Both the front tray bracket 8 and the side tray bracket 3 are provided with weight reduction holes 83. The design of the weight reduction holes 83 is to reduce the weight of the entire refrigerator support mechanism. By opening holes on the brackets, the amount of material used can be reduced, thereby reducing the weight of the entire structure.

[0026] The refrigerator panel includes: a panel main body 12 and a panel back plate 10. The panel main body 12 is fixed to the front side surface of the panel back plate 10 through screws and buckles; the panel back plate 10 is fixed to the front side surface of the front tray bracket 8 through screws, and the bottom of the panel back plate 10 is connected to the refrigerator compressor 4 through screws. The panel back plate 10 plays an intermediate transition role. Its front is connected to the panel main body 12 through 9 screws and 7 buckles, the back is connected to the front tray bracket 8 through 4 screws, and the bottom of the panel back plate 10 is connected to the refrigerator compressor 4 through 3 screws. A convex shape is made above the panel back plate 10, aiming to leave an operation space for opening the refrigerator flip cover. At the same time, for the processability of convenient sub-packaging, two groups of positioning holes are provided on the panel back plate 10, and correspondingly, two groups of positioning pins are provided on the panel main body 12, which can ensure the accuracy during the assembly of the panel main body 12 and improve the assembly efficiency.

[0027] The locking mechanism is located between the panel main body 12 and the panel back plate 10 to lock the vehicle-mounted refrigerator body 1, that is, to ensure that the vehicle-mounted refrigerator body 1 remains locked in a stationary state and prevent the refrigerator from accidentally opening due to vibration or other reasons during vehicle driving. Specifically, the locking mechanism includes: a panel handle 9, a locking hook 15, a locking rod 7, a handle base 77, a locking rod synchronizer 6, and a locking rod protective sleeve 5.

[0028] The locking hook 15 is arranged on the sleeper bracket 11. The refrigerator assembly is a moving part. To lock the refrigerator, the refrigerator assembly needs to be connected to a fixed part. Therefore, a locking hook 15 is riveted to the lower ends of the left and right sides of the sleeper bracket 11 respectively. The locking of the refrigerator is achieved by the bottom end of the locking rod 7 falling into the groove of the locking hook 15. When the refrigerator assembly is in the locked state, the bottom end of the locking rod 7 is located inside the locking hook 15. At this time, the locking hook 15 cooperates with the locking rod 7 on the refrigerator assembly to lock the refrigerator.

[0029] The top end of the locking rod 7 is connected to the panel handle 9. The connection method can be hinged, or a slideway can be provided on the panel handle 9, and the top end of the locking rod 7 is inserted into the slideway so that the panel handle 9 and the locking rod 7 are movably connected, realizing up and down movement without affecting the small-angle deflection of the locking rod 7. The handle base 77 is arranged on the panel back plate 10. The panel handle 9 is connected to the handle base 77 through a pin shaft. Two torsion springs are arranged on the pin shaft. One end of the torsion spring is fixed on the handle base 77, and the other end is in contact with the panel handle 9. The panel handle 9 can rotate around the pin shaft. When the panel handle 9 rotates a specific angle under the action of an external force and the external force is removed, the panel handle 9 can be reset under the action of the torsion spring.

[0030] An L-shaped bracket 34 is arranged at the front end of the side tray bracket 3. A guiding and positioning groove 44 is opened on the L-shaped bracket 34. The locking hook 15 is located outside the L-shaped bracket 34. The bottom end of the locking rod 7 is located in the guiding and positioning groove 44, and the groove depth of the locking hook 15 is less than the groove depth of the guiding and positioning groove 44. The guiding and positioning groove 44 helps the locking rod 7 to be accurately aligned and ensures a smooth locking process. When the panel handle 9 is turned upward around the hinge point, it drives the locking rod 7 to move upward until the bottom end of the locking rod 7 disengages from the locking hook 15.

[0031] When the refrigerator assembly needs to be pulled out, by applying a force to the panel handle 9, the panel handle 9 rotates around the pin shaft, thereby driving the locking rod 7 to move upward. Under the action of the guiding and positioning grooves 44 on both sides, the bottom end of the locking rod 7 is lifted upward. When the lifting stroke is greater than the groove depth of the locking hook 15, the locking rod 7 disengages from the locking hook 15. At this time, by applying a lateral pulling force to the panel handle 9, the vehicle-mounted refrigerator body 1 can be driven to move out along the three-stage slide rail 2 to unlock the refrigerator.

[0032] In addition, in order to ensure that the two bottom ends of the locking lever 7 move upward synchronously, a locking lever synchronizer 6 is welded to its bottom. Since the locking lever 7 has a sliding friction with the guiding positioning groove 44 and the locking hook 15, and the materials of the three are all metals, considering the NVH during driving, a locking lever protective sleeve 5 made of rubber is sleeved at the bottom end of the locking lever 7, which can greatly reduce the movement noise.

[0033] The utility model aims to install a large-capacity refrigerator on the original vehicle. The vehicle-mounted refrigerator is installed in the storage box under the bunk through a refrigerator carrier mechanism and a three-stage slide rail, and can realize the pulling function; at the same time, in order to fix the refrigerator in the non-use state, a locking mechanism is designed to lock the position of the refrigerator. A refrigerator panel is designed, and the locking mechanism and a self-resetting panel handle 9 are integrated on the refrigerator panel, which can realize the unlocking and positioning of the refrigerator sliding along the guide rail, and at the same time ensure the beautiful shape of the cab interior, and has the characteristics of high matching degree with the whole vehicle, large capacity of the carried refrigerator, reasonable space layout, and strong reliability.

[0034] The integrity and reasonable layout of the vehicle-mounted refrigerator assembly make use of the large storage space under the bunk, which can accommodate a large-capacity refrigerator. Moreover, the refrigerator compressor 4 is arranged under the vehicle-mounted refrigerator body 1, without occupying the storage space of the refrigerator, and the refrigerator has a large volume.

[0035] Relying on the three-stage slide rails 2 on both sides of the refrigerator carrier mechanism and the flat cab floor, the vehicle-mounted refrigerator assembly can be pulled out and pushed back, which better solves the problem that the refrigerator cannot be fixed and moved. To ensure the convenience of use, the slide rail stroke is designed to be 490 mm after being checked according to ergonomics. In this state, the refrigerator flip cover can be completely opened.

[0036] Since the self-weight of the refrigerator is large, the support and installation of the refrigerator are important contents of the utility model. By designing a set of refrigerator carrier mechanism, the vehicle-mounted refrigerator body 1 is provided with embedded nuts, and the refrigerator is firmly fixed by bolt connection. The firm fixation reduces the risk of the refrigerator shifting due to vibration or impact, and improves the driving safety.

[0037] The limit of the movement of the locking lever 7 is realized by extending an L-shaped bracket 34 on the side tray bracket 3, and the locking lever synchronizer 6 is added to ensure the synchronous movement of the two bottom ends of the locking lever 7. The locking problem of the refrigerator in the non-use state should be considered during the movement of the refrigerator. The refrigerator can be firmly fixed through a set of synchronous locking mechanisms, effectively preventing the refrigerator from coming out under extreme working conditions such as emergency braking and flipping the cab of the vehicle. When unlocking, it is convenient and labor-saving. At the same time, by using the transition inclination angle on the front of the locking hook 15, the locking lever 7 can move along the inclination angle of the locking hook into the hook groove of the locking hook 15 without operating the panel handle 9, and the refrigerator can be easily locked.

[0038] To ensure the overall beauty of the cab, a panel body 12 is provided to block the refrigerator and the locking mechanism.

[0039] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
