[0024] See Figure 1 、 2Figures 3 and 4 are schematic diagrams of a preferred embodiment of the present invention. The present invention relates to a hinge, particularly for mounting a refrigerator door on a vehicle, comprising: a first hinge seat 1, a second hinge seat 2, a first connecting rod 3, and a second connecting rod 4. The first hinge seat 1 is used to connect to a refrigerator body or cabinet body, and is provided with a first slide groove 11 on the first hinge seat 1; the second hinge seat 2 is used to connect to a refrigerator door or cabinet door, and is provided with a second slide groove 21 on the second hinge seat 2; the first connecting rod 3 is assembled in the first slide groove 11 of the first hinge seat 1 and can slide relative to it. The first connecting rod 3 has a first inner end 31 and a first outer end 32. The first outer end 32 extends from the first hinge seat 1 and bends downward to articulate with the second hinge seat 2, thereby determining the position between the first hinge seat 1 and the second hinge seat 2, and the second hinge seat 2 can rotate relative to each other using the hinge point. The first inner end 31 of the first connecting rod 3 is connected to the first hinge seat 1 through a multi-stage telescopic system, so that the first connecting rod 3 can obtain multiple sliding strokes in the first sliding groove 11, which is used to establish the slightly open state and the fully open state of the box door or cabinet door; in the slightly open state, the first connecting rod 3 moves forward a stroke and pushes the second hinge seat 2 to make a corresponding movement. The fully open state is a further action in the slightly open state, that is, the first connecting rod 3 moves forward another stroke. Similarly, the second hinge seat 2 follows the sliding of the first connecting rod 3 to make a corresponding matching movement. The second connecting rod 4 is assembled in the second sliding groove 21 of the second hinge seat 2 and can slide relatively; the second connecting rod 4 has a second inner end 41 and a second outer end 42, the second outer end 42 extends from the second hinge seat 2 and bends downward to cross the first outer end 32 of the first connecting rod 3, the second outer end 42 and the first outer end 32 are hingedly connected together at the intersection, so that the first connecting rod 3 and the second connecting rod 4 are connected together and can rotate relative to each other; and the protruding end of the second outer end 42 is hingedly connected to the first hinge seat 1, further determining the positional relationship between the first hinge seat 1 and the second hinge seat 2.

[0025] When the first connecting rod 3 pushes the second hinge seat 2, the hinge between the first connecting rod 3 and the second connecting rod 4 is utilized, and the first connecting rod 3 is hinged to the second hinge seat 2, and the second connecting rod 4 is hinged to the first hinge seat 1, so that the second hinge seat 2 performs a corresponding outward movement, that is, drives the box door or cabinet door to open.

[0026] In this embodiment, the multi-stage telescopic system includes an elastic member 51, which enables the slightly open state to be achieved by automatically springing open. In this slightly open state, the relative opening angle of the door or cabinet door is less than or equal to 30°. When the door or cabinet door is closed, the elastic member 51 accumulates force. When the user presses the corresponding button, the door or cabinet door is released. At this time, the elastic member 51 acts to move the first connecting rod 3 forward a stroke and push the second hinge base 2 to move accordingly. The door or cabinet door automatically springs open a small angle, achieving the slightly open function and facilitating subsequent door opening.

[0027] Figure 1 、2 As shown in FIGS. 2 and 3, in this embodiment, the multi-stage telescopic system further includes a first shaft rod 52 and a second shaft rod 53 sleeved inside the first shaft rod 52. The elastic member 51 is a compression spring and is sleeved on the outer periphery of the first shaft rod 52. The first shaft rod 52 is fixed on the first hinge seat 1. By pushing the second shaft rod 53 with the elastic member 51, the second shaft rod 53 extends from the first shaft rod 52 and drives the first connecting rod 3 to slide a corresponding stroke, thereby establishing a slightly open state. The second shaft rod 53 is a damper structure. A piston rod 531 extends from the second shaft rod 53. The outer extending end of the piston rod 531 is connected to the first connecting rod 3. The fully open state of the box door or cabinet door is established by the outer extending stroke of the piston rod 531. In the fully open state, the relative opening angle of the box door or cabinet door is at least 115°, obtaining a larger opening, which is beneficial for taking and placing items. In the slightly open state, the user can further pull the box door or cabinet door to the bottom by hand to achieve the fully open state, so as to take and place items from the box or cabinet. At the same time, during the process of manually pulling to the full open state, by using the function of the damper, a corresponding damping feeling is also obtained, with a slow-down effect, which improves the use experience and safety.

[0028] Figure 1 、 2 As shown in FIGS. 2 and 3, in this embodiment, the first shaft rod 52 is a tubular structure. A guiding long hole 521 is provided on the side wall of the first shaft rod 52, and the length direction of the guiding long hole 521 is the same as the sliding direction of the first connecting rod 3. A first clamping pin 532 is provided at one end of the second shaft rod 53, and an outwardly convex ring platform 533 is provided at the other end of the second shaft rod 53. After the corresponding end of the second shaft rod 53 is sleeved into the first shaft rod 52, the first clamping pin 532 is clamped into the guiding long hole 521 to establish an anti-disconnection connection. And by using the limitation and positioning of the first clamping pin 532 and the guiding long hole 521, the smoothness of the telescoping of the second shaft rod 53 is increased. In this embodiment, the first clamping pins 532 are arranged in a left-right comparison in the telescoping direction of the second shaft rod 53, improving the telescoping structure. The ring platform 533 presses the corresponding end of the elastic member 51, and the ring platform 533 is clamped in the first sliding groove 11 and can slide relatively. Further, an outwardly convex clamping foot 534 is provided on the ring platform 533. The clamping feet 534 are distributed on the left and right sides and the lower side in the moving direction of the ring platform. A first limiting groove 111 is provided on the corresponding inner side wall of the first sliding groove 11. The clamping feet 534 are clamped into the first limiting groove 111. The first limiting groove 111 guides the sliding of the clamping feet 534 and provides sliding limitation. This structure increases the assembly structure and improves the smoothness and accuracy of the telescoping of the second shaft rod 53.

[0029] When the box door or cabinet door is closed, the second hinge seat 2 drives the first connecting rod 3 to slide inward, and drives the second shaft rod 53 to retract into the first shaft rod 52. The ring platform 533 presses the elastic member 51, so that the elastic member 51 stores energy for the next slightly open operation.

[0030] Figure 1 、2 As shown in FIGS. 1 and 3, in this embodiment, the first hinge seat 1 includes a first U-shaped seat 12 and an end cover 13 for blocking one end of the first U-shaped seat. The first chute 11 is a U-shaped groove inside the first U-shaped seat. Second limiting grooves 112 are further provided on the left and right inner side walls of the first chute 11. The first connecting rod 3 is assembled into the first chute 11 and is snapped into the second limiting grooves 112 through second clamping pins 311 preset at the first inner end 31 of the first connecting rod 3, so as to guide the sliding and limit of the first connecting rod 3 and prevent excessive extension. In this embodiment, the second clamping pins 311 are integrally made with the connecting pins that connect the first inner end 31 of the first connecting rod 3 and the piston rod 531, simultaneously realizing the articulated connection between the first inner end 31 and the piston rod 531 and the outwardly protruding structural clamping pins, which is convenient for manufacturing and assembly. The multi-stage telescopic system of this embodiment is positioned on the end cover 13, that is, the corresponding end of the first shaft rod 52 is fixed on the end cover 13, and both ends of the elastic member 51 respectively support the end cover 13 and the ring platform 533; the end cover 13 is connected to the first U-shaped seat by a combined method of snap connection and screw locking, with a simple structure, which is convenient for manufacturing and assembly.

[0031] The second hinge seat 2 of this embodiment is constructed by a second U-shaped seat. The second chute 21 penetrates through the front and rear ends of the second hinge seat 2. The second chute 21 is a U-shaped groove inside the second U-shaped seat. Third limiting grooves 211 are further provided on the left and right inner side walls of the second chute 21. The second connecting rod 4 is assembled into the second chute 21 and is snapped into the third limiting grooves 211 through third clamping pins 411 preset at the second inner end 41 of the second connecting rod 4. This structure also realizes the relatively stable sliding and effective limiting between the second connecting rod 4 and the second hinge seat 2, ensuring the requirements of opening and closing.

[0032] Figure 1 、 2 As shown in FIGS. 1 and 3, in this embodiment, the first outer end 32 of the first connecting rod 3 has spaced-apart supporting feet 321 arranged in parallel. The supporting feet 321 are lowered and embedded into the groove positions reserved in the second hinge seat 2 and are connected through a first pin shaft 61 penetrating through, so that the first outer end 32 is hinged to the second hinge seat 2 together. The second outer end 42 of the second connecting rod 4 passes between the two supporting feet 321 of the first outer end 32 and is arranged in a crossed manner. At the crossing of the second outer end 42 and the first outer end 32, a second pin shaft 62 penetrates through for connection, so that the second outer end 42 is hinged to the first outer end 32 together; the extended end of the second outer end 42 is embedded into the groove positions reserved in the first hinge seat 1 and is connected through a third pin shaft 63 penetrating through, so that the second outer end 42 is also hinged to the first hinge seat 1 together. This structure is compact and reasonable, convenient for manufacturing and assembly, and obtains a tightly connected relationship with each other, and has relatively flexible and stable relative movement, good mechanical structure, better bearing capacity, and long service life. The first outer end 32 and the second outer end 42 are bent correspondingly to meet the tight closing and large-angle opening of the box door or cabinet door, improving the use experience.

[0033] The first connecting rod of the utility model can obtain multiple sliding strokes in the first chute, thereby establishing the slightly open state and the fully open state of the box door or cabinet door. In the slightly open state, the box door or cabinet door is automatically opened at a small angle, so that the user can further pull the box door or cabinet door to the bottom by hand to achieve the fully open state, so as to take and place items in or out of the box body or cabinet body. At the same time, a corresponding damping feeling is obtained during the process of manually pulling to the full open state, with a slow-down effect, enhancing the use experience and safety. The structure is compact and reasonable, especially for the installation of the box door of a vehicle-mounted refrigerator, improving the practicability of the vehicle-mounted refrigerator.
