Utility Model Content

[0004] In view of this, an object of the present invention is to provide a sealing structure for a double-door vehicle-mounted refrigerator door with excellent sealing performance.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A sealing structure for a double-door vehicle refrigerator door comprises a box body with an opening at the top, a box cover hingedly connected to the left and right sides of the upper end of the box body, and the two box covers seal the opening at the top of the box body when they are in a closed state. A sealing ring is provided at the upper end of the box body and surrounds the opening. The two box covers both press the sealing ring when they are in a closed state, and a sealing structure is provided between the two box covers to seal the gap therebetween.

[0020] The technical solution of the present invention will be described clearly and completely below with reference to 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 various components under a certain specific 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 for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0022] 1 to 5 , the present invention proposes a sealing structure for a double-door vehicle-mounted refrigerator door, comprising a box body 1 with an opening at the top, and a box cover 2 hingedly connected to the left and right sides of the upper end of the box body 1. The two box covers 2 seal the opening at the top of the box body 1 when they are in a closed state. The invention is characterized in that a sealing ring 3 surrounding the opening is provided at the upper end of the box body 1, and the two box covers 2 both press the sealing ring 3 when they are in a closed state, and a sealed structure capable of sealing the gap between the two box covers 2 is provided between the two box covers 2.

[0023] Specifically, the upper end surface of the box body 1 is provided with a sealing groove 11 surrounding the opening, and the sealing ring 3 is installed in the sealing groove 11 .

[0024] With this design, only the position on the sealing ring 3 corresponding to the gap between the two box covers 2 is not pressed by the box covers 2. Compared with the method of installing the sealing ring 3 on the box covers 2, the area that is not directly pressed is smaller, and the sealing performance and thermal insulation performance are better.

[0025] Example 1

[0026] Figures 1 to 4 disclose embodiment 1 of the present invention. In this embodiment, both cover plates 2 are provided with ridges 201 capable of pressing the sealing ring 3. The ridges 201 are used to press the sealing ring 3, thereby improving the sealing performance.

[0027] 2 and 5 , 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. A limiting boss 33 capable of abutting against the free end of the arc-shaped extension edge 32 is provided on the substrate 31. 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 constitute a C-shaped or G-shaped structure. The ridge 201 on the box cover 2 is pressed tightly against the top of the arc-shaped extension edge 32. The sealing ring 3 adopts such a structure that when the arcuate extension edge 32 is compressed, it bends downward, and the limiting surface 321 on one side of the arcuate extension edge 32 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 arcuate extension edge 32 contacts the protrusion 201; 2. The limiting surface 321 contacts the inner wall of the sealing groove 11; and 3. The base material 31 contacts the bottom surface of the sealing groove 11. This ensures a good seal. The opening between the free end of the arcuate extension edge 32 and the limiting boss 33 allows the arcuate extension edge 32 to deform. Even if the height position error of the protrusion 201 is large in some places, a good seal can still be formed.

[0028] In this embodiment, the two tank covers 2 are a left tank cover 21 and a right tank cover 22. The sealed structure includes a stop beam 4 provided on the right tank cover 22. The stop beam 4 extends leftward to below the left tank cover 21 to close the gap between the left and right tank covers 21, 22. The sealed structure also includes a first sealing strip 51 provided on the lower surface of the left tank cover 21 and compressed by the stop beam 4. A second sealing groove is provided on the lower surface of the left tank cover 21, parallel to the gap between the two tank covers 2. The first sealing strip 51 is mounted in the second sealing groove.

[0029] A second sealing strip 52 compressed by the stop beam 4 is provided between the stop beam 4 and the lower surface of the right box cover 22. A third sealing groove parallel to the gap between the two box covers 2 is provided on the lower surface of the right box cover 22, and the second sealing strip 52 is installed in the third sealing groove.

[0030] The guard beam 4 can be fixed or reversible. When configured as a reversible beam, a position-limiting structure is required on the box body 1. When the right box lid 22 is open, the reversible beam is approximately perpendicular to the right box lid 22. When the right box lid 22 is closed, the position-limiting structure causes the reversible beam to flip to a position approximately parallel to the right box lid 22, as shown in Figure 1. The design of the guard beam 4 closes the gap between the two box lids 2, improving thermal insulation.

[0031] In this embodiment, the first sealing strip 51 and the second sealing strip 52 can be configured to have the same cross-section as the sealing ring 3 described above. Such a design provides better sealing performance.

[0032] Example 2

[0033] FIG5 shows Example 2 of the present invention. This example has a similar structure to Example 1, with the only difference being that the sealing structure between the two box covers 2 is different from that in Example 1 in specific form.

[0034] In this embodiment, the sealed structure includes a fourth sealing groove 205 arranged on the side where the two box covers 2 face each other, and a hollow third sealing strip 6 is respectively provided in the two fourth sealing grooves 205. The cross-sections of the two third sealing strips 6 are both semicircular. When the two box covers 2 are in the closed state, the arc-shaped tops of the two third sealing strips 6 abut against each other to form a seal.

[0035] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by 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.
