[0042] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0043] The embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. The invention will be described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0044] In related technologies, the ejection mechanism typically includes a slider, guide bar, stop block, and coil spring assembly. After the drawer is unlocked, the slider slides along the guide bar under the action of the coil spring assembly, thus ejecting the drawer. However, existing ejection mechanisms are complex in structure and have a large number of parts. To solve the above problems, this utility model embodiment provides a vehicle-mounted refrigerator and vehicle, which are described in detail below.

[0045] Firstly, referring to Figures 1 to 4 The vehicle refrigerator provided in this embodiment of the present invention includes a cabinet 1, a drawer 2 and a fluid support rod. The drawer 2 is movably disposed inside the cabinet 1 and has a first position located inside the cabinet 1 and a second position located at least partially outside the cabinet 1. The fluid support rod is disposed on the cabinet 1 and has a movable first end. When the first end of the fluid support rod moves along a first direction, the first end of the fluid support rod pushes the drawer 2 so that the drawer 2 moves from the first position to the second position.

[0046] Drawer 2 is slidably disposed within the box body 1. Specifically, drawer 2 is slidably disposed within the box body 1 along its length. The length direction of the gas spring 4 is parallel to the length direction of the box body 1, which can be referenced... Figure 1 and Figure 3 The direction indicated by arrow C. In other configurations, drawer 2 can also be installed inside the box 1 by sliding up and down or diagonally. Figure 1 The drawer 2 shown is located inside the box 1, in the first position. Figure 3The drawer 2 shown is located outside the box 1 and is in the second position.

[0047] The vehicle refrigerator also includes a locking assembly 8, which locks the drawer 2 in a first position. After the drawer 2 is released from its locked position, the first end of the fluid support rod moves along a first direction and pushes the drawer 2, causing it to move from the first position to a second position, thereby pushing the drawer 2 out. The first direction is the direction from the first position to the second position, and the direction in which the drawer 2 is pushed out is consistent with the first direction, which can be referenced... Figure 3 , Figure 4 and Figure 9 The direction indicated by the arrow in the middle (D).

[0048] The fluid support rod is either a gas spring 4 or a hydraulic rod. When the fluid support rod is a gas spring 4, the fluid inside the fluid support rod is gas; when the fluid support rod is a hydraulic rod, the fluid inside the fluid support rod is oil or an oil-gas mixture. The number of fluid support rods can be set according to actual needs, for example, one or two. The fluid support rod can be partially or completely located inside the housing 1. The gas spring 4 or hydraulic rod includes a cylinder 41, a piston rod 42, and a piston slidably connected within the cylinder 41, with the piston rod 42 connected to the piston. When the fluid support rod is not subjected to external force, the piston rod 42 is preferably in an extended state. The first end of the fluid support rod can be the end of the piston rod 42 away from the cylinder 41, or the end of the cylinder 41 away from the piston rod 42.

[0049] The fluid support rod also has a fixed second end. The first end of the fluid support rod is the piston rod 42 away from the cylinder 41.

[0050] In the case of one end, as an example, refer to Figures 1 to 4 The first end of the fluid support rod opens to the side of the housing 1.

[0051] In the first example, when the fluid support rod is not subjected to external force, the piston rod 42 is in the extended state. When the drawer 2 is in the first position, the piston rod 42 is in the retracted state. After the lock of the drawer 2 is released, the first end of the fluid support rod moves in the first direction, that is, in the direction away from the second end of the fluid support rod, and the piston rod 42 extends. As another example, the orientation of the first end of the fluid support rod is opposite to that in the example above. When the fluid support rod is not subjected to external force, the piston rod 42 is in the retracted state. When the drawer 2 is in the first position, the piston rod 42 is in the extended state. After the lock of the drawer 2 is released, the first end of the fluid support rod moves in the first direction, that is, in the direction towards the second end of the fluid support rod, and the piston rod 42 retracts.

[0052] In this embodiment of the invention, the drawer 2 can be pushed out using a fluid support rod. Compared to a push-out structure that includes components such as a slider, guide bar, stop block, and coil spring assembly, this design is simpler and has fewer components. Furthermore, during the push-out process, the first end of the fluid support rod moves slowly, providing a damping effect. Additionally, during the push-in process, the fluid support rod also provides closing resistance.

[0053] In some embodiments, the fluid support rod is a gas spring 4 or a hydraulic rod, the gas spring 4 or hydraulic rod includes a cylinder 41 and a piston rod 42, the first end of the gas spring 4 or hydraulic rod is the end of the piston rod 42 away from the cylinder 41; when the drawer 2 is in the first position, the piston rod 42 is in the retracted state; when the drawer 2 is in the second position, the piston rod 42 is in the extended state.

[0054] The gas spring 4 can be a free-type gas spring, a common support gas spring, a self-locking gas spring, etc. When the fluid support rod is a gas spring 4, the cylinder 41 is filled with an inert gas at a certain pressure, which can be nitrogen. The gas pressure on both sides of the piston in the gas spring 4 is equal, but the force-bearing areas on both sides of the piston are different. After the drawer 2 is released from its locking position, the gas spring 4 uses the pressure difference on both sides of the piston to move the first end of the gas spring 4 until the piston rod 42 extends out of the cylinder 41 to the maximum designed extension length of the piston rod 42, at which point the piston rod 42 stops moving.

[0055] Specifically, the hydraulic rod is a non-powered hydraulic rod. When the fluid support rod is a hydraulic rod, the working medium inside the cylinder 41 is oil or an oil-gas mixture. As an example, when the hydraulic rod is not subjected to external force, the piston rod 42 is in the extended state. The piston divides the chamber inside the cylinder 41 into a rodless chamber and a rod chamber. During the process of pushing the drawer 2 in, an external force acts on the piston rod 42, causing the piston rod 42 to move from the extended state to the retracted state. The oil in the rodless chamber flows into the rod chamber, and the gas or spring in the rodless chamber is compressed. After the position of the drawer 2 is released, the gas in the rodless chamber expands or the spring returns to its original length, and the piston rod 42 moves from the retracted state to the extended state, causing the oil in the rod chamber to flow back to the rodless chamber.

[0056] The fluid support rod is preferably a gas spring 4. Compared to a hydraulic rod, the gas spring 4 is smaller in size and occupies less space, allowing it to be arranged inside the cabinet 1. In related technologies, the ejection mechanism also includes a silicone oil damping structure. The guide strip is coated with grease. The silicone oil in the silicone oil damping structure and the grease coated on the guide strip have high viscosity at low temperatures and low viscosity at high temperatures. This results in the slider being pulled out by the coil spring assembly at a slow speed in the refrigerator's cooling state and at a fast speed at high temperatures. Consequently, the drawer closing feels heavier at low temperatures and lighter at high temperatures. In this embodiment, the gas spring 4 mainly uses gas as its working medium. The gas pressure changes little at high and low temperatures. Therefore, the thrust change of the gas spring 4 at high and low temperatures is less than the thrust change of the ejection structure including the silicone oil damping structure at high and low temperatures, which can reduce the difference in the ejection speed or the push-in feel of the drawer 2 at high and low temperatures.

[0057] The second end of the gas spring 4 or hydraulic rod is fixed at the end of the cylinder 41 away from the piston rod 42. When the drawer 2 is locked in the first position, the drawer 2 presses against the piston rod 42, and the drawer 2 applies a horizontal external force to the piston rod 42 to keep the piston rod 42 in the retracted state. After the drawer 2 is released from its locked position, the first end of the gas spring 4 or hydraulic rod moves away from the second end of the gas spring 4 or hydraulic rod and pushes the drawer 2, causing the drawer 2 to move from the first position to the second position, thereby pushing the drawer 2 out.

[0058] When drawer 2 is at least partially outside the box 1, the user can push drawer 2 toward the box 1 to push drawer 2 into the box 1. During the process of pushing drawer 2 in, piston rod 42 moves toward cylinder 41 under the force applied by the user until drawer 2 is in the first position, at which point piston rod 42 is pushed back to the retracted state.

[0059] When the piston rod 42 is in the retracted state, the length of the piston rod 42 extending out of the cylinder body 41 is less than half of the maximum designed extension length of the piston rod 42. Preferably, the length of the piston rod 42 extending out of the cylinder body 41 is the minimum designed extension length of the piston rod 42. The length of the piston rod 42 extending out of the cylinder body 41 is also the distance between the end face of the cylinder body 41 near the piston rod 42 and the end face of the piston rod 42 away from the cylinder body 41 along the length direction of the gas spring 4.

[0060] In some embodiments, when the piston rod 42 is in the retracted state, the length of the piston rod 42 extending out of the cylinder 41 is the minimum designed extension length of the piston rod 42; and / or, when the piston rod 42 is in the extended state, the length of the piston rod 42 extending out of the cylinder 41 is the maximum designed extension length of the piston rod 42.

[0061] in, Figure 6 The length of the piston rod 42 extending out of the cylinder body 41 in the gas spring 4 or hydraulic rod shown is the minimum designed extension length of the piston rod 42. The minimum designed extension length of the piston rod 42 can be referred to... Figure 6 Lmin is shown in the figure. Figure 5 The length of the piston rod 42 extending out of the cylinder body 41 in the gas spring 4 or hydraulic rod shown is the maximum designed extension length of the piston rod 42. The maximum designed extension length of the piston rod 42 can be referred to... Figure 5 Lmax is shown in the figure. The maximum designed extension length of the piston rod 42 is also the distance between the end face of the cylinder body 41 near the piston rod 42 and the end face of the piston rod 42 away from the cylinder body 41 when the gas spring 4 or hydraulic rod is in the free state.

[0062] It should be noted that the gas spring 4 or hydraulic rod is a standard part. The maximum design extension length of the piston rod 42 can be measured when the gas spring 4 or hydraulic rod is in a free state. The parameters of the gas spring 4 or hydraulic rod include the stroke of the gas spring 4, which is the difference between the maximum design extension length and the minimum design extension length of the piston rod 42. Once the specifications of the gas spring 4 or hydraulic rod are determined, the minimum design extension length of the piston rod 42 can be calculated based on the maximum design extension length and the stroke of the gas spring 4.

[0063] In this embodiment, when drawer 2 is in the first position, the length of piston rod 42 extending out of cylinder 41 is the minimum designed extension length of piston rod 42. During the process of drawer 2 being pushed out, piston rod 42 moves away from cylinder 41 until the length of piston rod 42 extending out of cylinder 41 reaches the maximum designed extension length of piston rod 42, at which point piston rod 42 stops moving. Throughout the process, the pushing distance of drawer 2, which is also the stroke of gas spring 4 or hydraulic rod, can make the most of gas spring 4 or hydraulic rod.

[0064] In some embodiments, drawer 2 includes a first protrusion 21. When the first end of the gas spring 4 or hydraulic rod moves away from the second end of the gas spring 4 or hydraulic rod, the first end of the gas spring 4 or hydraulic rod pushes the first protrusion 21. The first protrusion 21 is located at one end of drawer 2 near the door panel 3 of the vehicle refrigerator. Drawer 2 includes a bottom plate 23, and the first protrusion 21 protrudes downward from the bottom plate 23. In this embodiment, the piston rod 42 directly pushes the first protrusion 21 in drawer 2, and the thrust can be precisely applied to the force-bearing point of drawer 2, simplifying the force transmission path and eliminating the need for a complex force transmission mechanism.

[0065] In some embodiments, a buffer pad 5 is provided on the first protrusion 21; when the drawer 2 is in the first position, the buffer pad 5 abuts against the first end of the gas spring 4 or the hydraulic rod.

[0066] The buffer pad 5 can be made of rubber. Along the length of the box 1, the projected area of ​​the buffer pad 5 on the first protrusion 21 is larger than the projected area of ​​the first end of the gas spring 4 or hydraulic rod on the first protrusion 21. The shape of the buffer pad 5 can be circular, square, etc. Since the buffer pad 5 is not connected to the first end of the gas spring 4 or hydraulic rod, after the drawer 2 is pushed out by the gas spring 4 or hydraulic rod, the user can continue to pull the drawer 2 open according to actual needs. In this embodiment, by setting the buffer pad 5, on the one hand, it can avoid the noise caused by the first protrusion 21 directly hitting the first end of the gas spring 4 or hydraulic rod when the drawer 2 is pushed into the box 1; on the other hand, it can prevent the first end of the gas spring 4 or hydraulic rod or the first protrusion 21 from deforming.

[0067] In some embodiments, the cabinet 1 has a side opening 11, and a cylinder 41 is located at one end of the cabinet 1 near the side opening 11. The side opening 11 is located on one side of the cabinet 1 along its length. The cylinder 41 is preferably disposed inside the cabinet 1. The vehicle refrigerator also includes a door panel 3 connected to the drawer 2. When the drawer 2 is in a first position, the door panel 3 closes the side opening 11. The door panel 3 is detachably connected to the drawer 2.

[0068] In some embodiments, the cylinder 41 is disposed in the housing 1 and located below the bottom plate 23 in the drawer 2. Preferably, the cylinder 41 is disposed inside the housing 1. In this embodiment, the arrangement of the cylinder 41 makes full use of the space below the bottom plate 23 inside the housing 1, avoiding the additional occupation of space outside the housing 1. In other embodiments, the cylinder 41 may also be located on one side of the drawer 2 along its width.

[0069] In some embodiments, refer to Figure 7 The housing 1 includes a base 6 and a housing body. The base 6 is located at the bottom of the housing body, and the cylinder 41 is detachably connected to the base 6. The base 6 is detachably connected to the inner bottom wall of the housing body. The base 6 can be fastened to the housing 1 via a first threaded component, such as a screw or bolt. In this embodiment, the cylinder 41 is detachably connected to the base 6, facilitating the maintenance and replacement of the gas spring 4.

[0070] In some embodiments, refer to Figure 2 , Figures 5 to 7 The cylinder body 41 is connected to a connector 43 at the end away from the piston rod 42. The connector 43 is connected to the first mounting hole 61 in the base 6 through a threaded fastener 9. A limit hole 62 is provided on the base 6, and the limit hole 62 is engaged with the outer surface of the cylinder body 41.

[0071] The connector 43 has a second mounting hole, which is a smooth hole, while the first mounting hole 61 is a threaded hole. A threaded fastener 9 passes through the second mounting hole and is threadedly connected to the first mounting hole 61. The threaded fastener 9 can be a screw, bolt, etc. Along the length of the housing 1, a limiting through hole 62 is located between the first mounting hole 61 and the side opening 11. The limiting through hole 62 specifically has a clearance fit with the outer surface of the cylinder 41. The axial direction of the limiting through hole 62 is parallel to the axial direction of the cylinder 41.

[0072] Reference Figure 7 The installation process of the gas spring 4 or hydraulic rod is as follows: The gas spring 4 or hydraulic rod is pushed into the limiting through hole 62 horizontally until the connector 43 is pushed into the first mounting hole 61, at which point the pushing stops. Then, the gas spring 4 or hydraulic rod is fastened to the base 6 using threaded fasteners 9. In this embodiment, the gas spring 4 or hydraulic rod is fastened to the base 6 using threaded fasteners 9, and the limiting through hole 62 engages with the outer surface of the cylinder body 41 to limit the cylinder body 41 radially, thereby improving the stability of the gas spring 4 or hydraulic rod.

[0073] In some embodiments, the stroke of piston rod 42 is between 40mm and 70mm; and / or, the stroke of piston rod 42 is less than or equal to the stroke of drawer 2. The stroke of piston rod 42 refers to the distance the piston rod 42 moves from fully retracted to fully extended. The stroke of piston rod 42 can be 40mm, 45mm, 50mm, 55mm, 60mm, 70mm, etc. The stroke of piston rod 42 is preferably 55mm. The stroke of drawer 2 refers to the distance the drawer 2 moves from its first position to being fully extended.

[0074] In this embodiment, when the stroke of the piston rod 42 is within the aforementioned range, it can push the drawer 2 out a sufficient distance, thereby leaving enough space between the door panel 3 and the cabinet 1. This allows the user to reach out and grasp the edge of the door panel 3 and pull the drawer 2 outward. Simultaneously, the gas spring 4 or hydraulic rod will not be excessively large along its length, thus reducing the space occupied by the gas spring 4 or hydraulic rod. Furthermore, when the stroke of the piston rod 42 is less than the stroke of the drawer 2, during the process of pushing the drawer 2 back, it is only necessary to overcome the closing resistance provided by the gas spring 4 or hydraulic rod within a portion of the drawer 2's stroke, which improves the user experience.

[0075] In some embodiments, refer to Figure 7 and Figure 8 The vehicle refrigerator also includes a sliding assembly 7, which includes a first sliding member and a second sliding member. The first sliding member is slidably connected to the second sliding member, the first sliding member is fastened to the drawer 2, and the second sliding member is fastened to the base 6.

[0076] The number of sliding components 7 can be set according to actual needs, for example, one or two. Preferably, there are two sliding components 7, distributed on both sides of the base 6 along its width. The first sliding component can be fastened to the drawer 2 via a second threaded component, and the second sliding component can be fastened to the base 6 via a third threaded component. The second and third threaded components can be screws, bolts, etc.

[0077] One of the first sliding member 31 and the second sliding member 32 is provided with a slide rail, and the other is provided with a guide groove. The slide rail is slidably fitted into the guide groove. For example, the first sliding member 31 is provided with a slide rail, and the second sliding member 32 is provided with a guide groove. The lower end of the slide rail is embedded in the guide groove and can slide along the length of the guide groove. In this embodiment, the sliding component 7 improves the smoothness and stability when the drawer 2 slides out or is pushed into the cabinet 1. The contact area between the first sliding member and the second sliding member is coated with lubricating oil.

[0078] In some embodiments, refer to Figure 9 The vehicle refrigerator also includes a locking assembly 8, which includes a locking tongue 81 and a drive mechanism. The locking tongue 81 is located inside the cabinet 1 and can swing between a locked position and an unlocked position relative to the cabinet 1. The drive mechanism is used to drive the locking tongue 81 to swing. In the locked position, the locking tongue 81 abuts against the second protrusion 22 in the drawer 2 to lock the position of the drawer 2 in a first position. In the unlocked position, the locking tongue 81 avoids the second protrusion 22 in the drawer 2 to release the lock on the position of the drawer 2.

[0079] When drawer 2 is locked in the first position, piston rod 42 is in the retracted state. After the lock on drawer 2 is released, the first end of gas spring 4 or hydraulic rod moves away from the second end of gas spring 4 or hydraulic rod and pushes drawer 2, causing drawer 2 to move from the first position to the second position, thereby pushing drawer 2 out. Therefore, after the lock on drawer 2 is released, drawer 2 can be pushed out by gas spring 4 or hydraulic rod.

[0080] The second protrusion 22 protrudes downward from the base plate 23. The second protrusion 22 and the first protrusion 21 are located at opposite ends of the drawer 2 along its length, and the length of the drawer 2 is parallel to the length of the cabinet 1. The lock assembly 8 also includes a mounting shaft 84, through which the latch 81 is rotatably connected to the base 6. The drive mechanism includes a drive element 82 and a push rod 83. The drive element 82 is connected to the push rod 83, and the drive element 82 is used to drive the push rod 83 to perform linear reciprocating motion along the length of the cabinet 1. The drive element 82 can be a linear motor.

[0081] The latch 81 has a first end 811 and a second end 812, and a mounting shaft 84 is located between the first end 811 and the second end 812 of the latch 81. In the locked position, the second end 812 of the latch 81 abuts against the second protrusion 22 in the drawer 2, and the first end 811 of the latch 81 contacts the push rod 83. In the released position, the second end 812 of the latch 81 avoids the second protrusion 22 in the drawer 2.

[0082] Figure 9 When the latch 81 is in the locked position, it abuts against the second protrusion 22 in the drawer 2 to lock the position of the drawer 2. When the drawer 2 is released from the lock, the drive unit 82 drives the push rod 83 to move toward the latch 81. During the movement of the push rod 83 toward the latch 81, the push rod 83 pushes the first end 811 of the latch 81, causing the latch 81 to rotate counterclockwise. After the latch 81 rotates counterclockwise by a certain angle, the second end 812 of the latch 81 avoids the second protrusion 22 in the drawer 2.

[0083] The lock assembly 8 also includes a reset member, which is used to swing the latch 81 from the released position to the locked position. The reset member can be a torsion spring, which can be mounted on the mounting shaft 84. After the second end 812 of the latch 81 avoids the second protrusion 22 in the drawer 2, the drive member 82 drives the push rod 83 to move away from the latch 81. After the push rod 83 moves away from the latch 81, the latch 81 swings from the released position to the locked position under the action of the reset member. When the user needs to close the drawer 2, he / she manually pushes the drawer 2 into the box 1. During the process of pushing the drawer 2 in, the second protrusion 22 will contact the top of the latch 81 and push the latch 81 to swing so that the drawer 2 can be pushed in smoothly. After the drawer 2 is fully pushed into the box 1, the latch 81 resets and abuts against the second protrusion 22 in the drawer 2 again to lock the position of the drawer 2.
