[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0022] Reference Figures 1 to 6 A vehicle refrigerator with a flip beam 4 structure includes a box body 1 with an opening at the top, a first box cover 22 is hingedly connected to the right side of the upper end of the box body 1, a second box cover 21 is hingedly connected to the left side of the upper end of the box body 1, and a top plate 105 is fixed to the upper end of the box body 1. The left part of the first box cover 22, that is, the free end of the first box cover 22 is rotatably provided with a flip beam 4, the first box cover 22 is provided with an elastic member 7 capable of driving the flip beam 4 to flip to a retracted state when it is opened, and a push piece connected to the flip beam 4 is movably provided on the first box cover 22, the lower end of the push piece protrudes from the lower surface of the first box cover 22, when the first box cover 22 is rotated downward to close, the top plate 105 presses the lower end of the push piece to make the push piece move relative to the first box cover 22, and then drives the flip beam 4 to flip to an unfolded state, at which time the flip beam 4 is roughly parallel to the bottom surface of the first box cover 22. When the second box cover 21 and the first box cover 22 are both in the closed state, the left part of the flip beam 4 in the unfolded state extends below the second box cover 21 to block the gap between the second box cover 21 and the first box cover 22. The design of the flip beam 4 can close the gap between the two boxes when the second box cover 21 and the first box cover 22 are both closed, thereby improving the sealing and heat preservation. When the first box cover 22 is closed, the flip beam 4 can automatically rotate to the unfolded state, and when the first box cover 22 is opened, the flip beam 4 can automatically rotate to the retracted state, which is very convenient to use.

[0023] Example 1

[0024] Figures 1 to 4 Embodiment 1 of the utility model is shown. In this embodiment, the pushing member includes a rack 131 which is movably installed on the first box cover 22 up and down. A gear 132 meshing with the rack 131 is provided on the flip beam 4. The elastic member 7 is connected between the first box cover 22 and the rack 131. The elastic member 7 can be a compression spring, a torsion spring, a tension spring, an elastic rope or the like, among which a compression spring is the best.

[0025] When the first box cover 22 is rotated downward to close, the top plate 105 presses the rack 131 to make the rack 131 move upward relative to the first box cover 22 and cause the elastic member 7 to produce elastic deformation. In the process of the rack 131 moving upward relative to the first box cover 22, the gear 132 is driven to rotate, thereby driving the flip beam 4 to flip to the unfolded state. At this time, the flip beam 4 is roughly parallel to the lower surfaces of the first box cover 22 and the second box cover 21, and the wider side surface of the flip beam 4 is in contact with the lower surfaces of the first box cover 22 and the second box cover 21; when the first box cover 22 is rotated upward to open, the elastic member 7 elastically recovers and drives the rack 131 to move downward relative to the first box cover 22, thereby driving the gear 132 and the flip beam 4 to rotate, so that the flip beam 4 automatically turns to the retracted state.

[0026] In order to guide the rack 131 , a vertical hole 225 for guiding the rack 131 is provided on the first box cover 22 , and the lower end of the rack 131 protrudes from the lower end of the vertical hole 225 .

[0027] There are two solutions for the flip beam 4. First, the flip beam 4 includes a rigid shaft core 41 and a soft sealing block 42 sleeved on the shaft core 41, and the gear 132 is installed at the end of the shaft core 41 through a key. Figure 1 In the unfolded state shown, the lower surface of the second box cover 21 and the lower surface of the first box cover 22 respectively abut against the upper surface of the soft sealing block 42 to achieve sealing. Second, the entire flip beam 4 is a rigid body, and sealing strips that can abut against the flip beam 4 are correspondingly provided on the lower surfaces of the first box cover 22 and the second box cover 21 to further improve the sealing and heat preservation properties.

[0028] In this embodiment, the above-mentioned rack 131 can also be set to an arc shape, and accordingly, the vertical hole 225 is also set to a corresponding arc hole. When the top plate presses the rack 131, the rack 131 moves along the arc hole, thereby driving the gear 132 and the flip beam 4 to rotate.

[0029] Example 2

[0030] Figures 5 and 6 Embodiment 2 of the utility model is shown. In this embodiment, the push member includes a push rod 5 which is movably installed on the first box cover 22 up and down. The push rod 5 is provided with an elongated hole 51 arranged along its length direction. A crank 43 is fixedly provided on the flip beam 4. One end of the crank 43 is inserted into the elongated hole 51. The elastic member 7 is connected between the first box cover 22 and the push rod 5. The elastic member 7 is connected between the first box cover 22 and the rack 131. The elastic member 7 can be a compression spring, a torsion spring, a tension spring, an elastic rope or the like, among which a compression spring is the best.

[0031] When the first box cover 22 is rotated downward to close, the top plate 105 presses the push rod 5, causing the push rod 5 to move upward relative to the first box cover 22 and causing the elastic member 7 to produce elastic deformation. During the upward movement of the push rod relative to the first box cover 22, the push crank 43 is pushed to rotate so that the flip beam 4 is flipped to the expanded state; when the first box cover 22 is rotated upward to open, the elastic member 7 elastically recovers and drives the push rod 5 to move downward relative to the first box cover 22. At this time, the crank 43 of the flip beam 4 rotates under the push of the other end of the long hole 51, so that the flip beam 4 is automatically flipped to the retracted state.

[0032] In order to guide the rack 131 , a vertical hole 225 for guiding the push rod 5 is provided on the first box cover 22 , and the lower end of the push rod 5 protrudes from the lower end of the vertical hole 225 .

[0033] In this embodiment, the turnover beam 4 includes a rigid shaft core 41 and a soft sealing block 42 sleeved on the shaft core 41 , and a crank 43 is fixed to the end of the shaft core 41 .

[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
