[0034] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Reference Figures 1 to 12 The utility model proposes a double-door refrigerator cover structure of a vehicle-mounted refrigerator, comprising a box body 1 with an opening at the top, a left box cover 21 hingedly connected to the left side of the upper end of the box body 1, and a right box cover 22 hingedly connected to the right side of the upper end of the box body 1, characterized in that a flip beam 4 is movably provided on the left part of the right box cover 22, and an elastic member 7 is provided on the right box cover 22 which can drive the flip beam 4 to flip to a retracted state when the right box cover 22 is opened, a limiting structure is provided on the box body 1, and a transmission member connected to the flip beam 4 is provided on the right box cover 22. When the right box cover 22 is closed, the limiting structure presses the transmission member to drive the flip beam 4 to flip to an unfolded state. When the left box cover 21 and the right box cover 22 are both in a closed state, the left part of the flip beam 4 extends below the left box cover 21 to block the gap between the left box cover 21 and the right box cover 22.

[0036] Example 1

[0037] Figures 1 to 6 The embodiment 1 of the utility model is shown. In this embodiment, the transmission member includes a connecting rod 42 fixed to the flip beam 4, and the limiting structure includes a limiting rod 6 arranged on the box body 1. When the right box cover 22 is closed, the limiting rod 6 presses the connecting rod 42 to flip the flip beam 4 to the unfolded state. The flip beam 4 is a rigid body, and a first sealing strip 51 is arranged between the bottom surface of the left box cover 21 and the flip beam 4, and a second sealing strip 52 is arranged between the bottom surface of the right box cover 22 and the flip beam 4.

[0038] When the right box cover 22 is opened, under the elastic force of the elastic member 7, the flip beam 4 flips to the stowed state. Figure 1 As shown, the flip beam 4 is substantially perpendicular to the bottom surface of the right box cover 22; when the right box cover 22 is closed, the flip beam 4 can be driven to flip to the unfolded state under the action of the limit rod 6. Figure 2 , Figure 4 As shown, the flip beam 4 is substantially parallel to the bottom surface of the right box cover 22. The design of the flip beam 4 can close the gap between the two box covers and improve the heat preservation.

[0039] The elastic member 7 is preferably a torsion spring. In addition, an elastic device such as a tension spring or an elastic rope may also be used.

[0040] The flip beam 4 is a rotating member, specifically, a main shaft 41 hinged to the right box cover 22 is fixed at one end of the flip beam 4, and a connecting rod 42 is fixed on the main shaft 41. The flip beam 4 adopts such an installation structure, which is simple, practical and low in cost.

[0041] In a further improvement of the utility model, the limit rod 6 is detachably mounted on the box body 1. After the vehicle refrigerator is used for a period of time, the limit rod 6 and the connecting rod 42 will be subject to certain wear, which may cause the flip beam 4 to be unable to press the first sealing strip 51 and the second sealing strip 52, thereby reducing the sealing and heat preservation performance. The limit rod 6 is detachable and can be replaced regularly to maintain excellent sealing and heat preservation performance at the flip beam 4.

[0042] Reference Figure 1 and Figure 2 The upper end of the box body 1 is provided with a sealing groove 11 surrounding the opening, and the sealing groove 11 is installed with a sealing ring 3. The left box cover 21 and the right box cover 22 are both provided with convex strips 201 corresponding to the sealing ring 3. When the left box cover 21 and the right box cover 22 are both in the closed state, all the convex strips 201 press the sealing ring 3. With such a design, only the position on the sealing ring 3 corresponding to the gap between the two box covers is not pressed by the box covers. Compared with the method of installing the sealing ring 3 on the box cover, the area that is not directly pressed is smaller, and the sealing performance and heat preservation performance are better.

[0043] Furthermore, the sealing ring 3 includes a substrate 31 located at the bottom of the sealing groove 11, and an arc-shaped extension edge 32 integrally connected to one side of the upper surface of the substrate 31, a limiting surface 321 is provided on the outer surface of the arc-shaped extension edge 32, which is in contact with the inner wall of the sealing groove 11, and a limiting boss 33 is provided on the substrate 31, which can abut against the free end of the arc-shaped extension edge 32, and an opening is left between the free end of the arc-shaped extension edge 32 and the limiting boss 33. The arc-shaped extension edge 32, the substrate 31, and the limiting boss 33 together form a C-shaped or G-shaped structure, the box cover is pressed against the top of the arc-shaped extension edge 32, and the convex strip 201 on the box cover is pressed against the top of the arc-shaped extension edge 32. The sealing ring 3 adopts such a structure that when the arc-shaped extension edge 32 is compressed, the arc-shaped extension edge 32 will bend downward, and at the same time, the limiting surface 321 on one side thereof presses against the inner wall of the sealing groove 11. The three contact points on the sealing ring 3 are: 1. The upper surface of the arc-shaped extension edge 32 contacts the convex strip 201; 2. The limiting surface 321 contacts the inner wall of the sealing groove 11; 3. The base material 31 contacts the bottom surface of the sealing groove 11. Therefore, a good seal can be formed. The opening between the free end of the arc-shaped extension edge 32 and the limiting boss 33 allows the arc-shaped extension edge 32 to have a certain deformation space. Even if the height position error of the convex strip 201 at some positions is large, a good seal can be formed.

[0044] The lower surface of the left box cover 21 is provided with a second sealing groove parallel to the flip beam 4, and the first sealing strip 51 is installed in the second sealing groove. The lower surface of the right box cover 22 is provided with a third sealing groove parallel to the flip beam 4, and the first sealing strip 51 is installed in the third sealing groove. In order to further improve the sealing performance, the cross-sectional shapes of the first sealing strip 51 and the second sealing strip 52 are the same as the cross-sectional shape of the sealing ring 3.

[0045] Reference Figure 5 In this embodiment, the limiting rod 6 can be installed in the following manner. A vertical plate 12 is provided on the box body 1, and the limiting rod 6 is screwed to the vertical plate 12. A conical surface 61 is provided on the outer surface of the limiting rod 6. When the right box cover 22 is closed, the connecting rod 42 abuts against the conical surface 61, and the conical surface 61 of the limiting rod 6 moves axially when the limiting rod 6 is screwed. A first screw 62 is fixed on the limiting rod 6, and a nut or threaded tube 81 meshing with the first screw 62 is fixed on the vertical plate 12. In this solution, when the limiting rod 6 or the connecting rod 42 is worn, it can be adjusted by screwing the limiting rod 6 to change the axial position of the contact between the limiting rod 6 and the connecting rod 42, increase the outer diameter at the contact position, and enable the flip beam 4 to rotate into place when the box cover is closed, thereby maintaining excellent sealing and thermal insulation.

[0046] Example 2

[0047] Figure 7The schematic diagram of the position adjustment method of the limit rod of Example 2 of the utility model is shown. In this example, a vertical plate 12 is provided on the box body 1, and the limit rod 6 is screwed with the vertical plate 12. A conical surface 61 is provided on the outer surface of the limit rod 6. When the right box cover 22 is closed, the connecting rod 42 abuts against the conical surface 61, and the conical surface 61 of the limit rod 6 moves axially when the limit rod 6 is screwed. A second screw 82 is fixed on the vertical plate 12, and a screw hole 63 engaged with the second screw 82 is provided on the limit rod 6. In this scheme, when the limit rod 6 or the connecting rod 42 is worn, it can be adjusted by screwing the limit rod 6, changing the axial position of the contact between the limit rod 6 and the connecting rod 42, increasing the outer diameter at the contact position, so that the flip beam 4 can be rotated into place when the box cover is closed, and maintaining excellent sealing and heat preservation.

[0048] Example 3

[0049] Figure 8 The schematic diagram of the position adjustment method of the limiting rod of the third embodiment of the utility model is shown. In this example, the box body 1 is provided with a vertical plate 12, and the third screw 83 is fixed on the vertical plate 12. The limiting rod 6 is cylindrical, and the limiting rod 6 is provided with an eccentric screw hole 64 parallel to its axis, and the eccentric screw hole 64 is engaged with the third screw 83. In this scheme, when the limiting rod 6 or the connecting rod 42 is worn, it can be adjusted by screwing the limiting rod 6 to change the circumferential position of the contact between the limiting rod 6 and the connecting rod 42, increase the distance between the contact position and the axis of the third screw 83, so that the flip beam 4 can be rotated into place when the box cover is closed, and maintain excellent sealing and heat preservation.

[0050] In addition, in Example 3, the limiting rod 6 can also be deformed as follows, such as designing its cross section to be cam-shaped, or fixing the third screw 83 on the limiting rod 6, and providing a nut or threaded tube 81 on the box body 1 that engages with the third screw 83.

The elastic member 7 is a compression spring provided between the right box cover 22 and the upper end of the rack 131.

[0054] When the right box cover 22 is closed, the limiting table 105 presses the rack 131 to make the rack 131 move upward relative to the right box cover 22 and make the elastic member 7 produce elastic deformation. When the rack 131 moves upward relative to the right box cover 22, it drives the flip beam 4 to flip to the unfolded state; when the right box cover 22 is opened, the elastic member 7 gradually recovers elastically and drives the rack 131 to move downward relative to the right box cover 22. When the rack 131 moves downward relative to the right box cover 22, it drives the flip beam 4 to flip to the retracted state. Specifically, a vertical hole 225 for guiding the rack 131 is provided on the right box cover 22, and the lower end of the rack 131 extends from the lower end of the vertical hole 225.

[0055] Difference 2: In this embodiment, the flip beam 4 includes a rigid shaft core 41 and a soft sealing block 43 sleeved on the shaft core 41, and the gear 132 is mounted on the free end of the shaft core 41 through a key.
