Furthermore, it should be understood that although the terms first, second, etc. may be used herein to describe various elements or structures, these described objects should not be limited by the aforementioned terms. The above terms are only used to distinguish these description objects from each other. For example, the first optical glue may be called the second optical glue, and similarly, the second optical glue may also be called the first optical glue, which does not deviate from the protection scope of this application.

As shown in Figures 1 to 3, the embodiments provided by the present invention disclose a refrigerator. The refrigerator includes a cabinet (not shown) and a refrigerator door 10 for opening or closing the cabinet. The cabinet defines storage. Compartments, the number and structure of storage compartments can be configured according to different needs. The storage compartment usually includes a refrigerator compartment and a freezer compartment. Generally, the refrigerator door 10 is provided with a storage area (not shown) for storing articles, so as to improve the convenience for the user to take the articles.

The refrigerator door 10 includes a main body 12 and a display assembly 14 provided on the main body 12. The display assembly 14 includes a transparent cover plate 16, a display device with a display screen 18, and a touch film provided between the transparent cover plate 16 and the display screen 18. twenty two. Further, the transparent cover plate 16 extends along a curve, and the extension path of the touch film 22 is parallel to the extension path of the transparent cover plate 16.

In the preferred embodiment, since the transparent cover 16 extends along a curve, the extension path of the touch film 22 is parallel to the extension path of the transparent cover 16, so that the distance between any position of the transparent cover 16 and the touch film 22 is Equally, no matter where the transparent cover 16 is touched, the display device can be operated well, which greatly improves the sensitivity and reliability of touch.

Specifically, in this embodiment, the transparent cover 16 and the touch film 22 both extend along an arc, and the transparent cover 16 and the touch film 22 are concentric, and the arc center and the display screen 18 are located on the same side of the transparent cover 16. This ensures that the vertical distance from any position of the transparent cover 16 to the corresponding position of the touch film 22 is equal, and the sensitivity and reliability of the touch are ensured. Of course, the transparent cover 16 and the touch film 22 are not only arranged to extend along an arc, but also can be arranged to extend along other parallel curves, as long as the vertical distance from any position of the transparent cover 16 to the corresponding position of the touch film 22 is equal. can. Furthermore, light is transmitted between the transparent cover 16 and the touch film 22, and light is also transmitted between the touch film 22 and the display screen 18.

Generally, the display device also includes various electrical modules 28 connected to the display screen. In this preferred embodiment, the display screen 18 is set as a flat screen, and a plane passing through the arc center line of the transparent cover 16 and bisecting the touch film 22 is defined as the first plane, and the display screen 18 is perpendicular to the first plane. In addition, the two ends of the transparent cover 16 protrude from the two ends of the display screen 18. Of course, the display screen 18 can also be set as a curved screen. Specifically, the curved screen is concentric with the transparent cover 16, and the curvature of the curved screen is smaller than that of the transparent cover 16, ensuring that both ends of the transparent cover 16 protrude from the curved screen. The ends.

In this preferred embodiment, the transparent cover plate 16 is glass, and the thickness of the transparent cover plate 16 is 3.2 mm. Of course, the transparent cover 16 can also be made of other transparent materials except glass, and the thickness of the transparent cover 16 can also be set to other thickness values.

The transparent cover 16 has an inner surface 24 closer to the touch film 22 and an outer surface 26 opposite to the inner surface 24. The inner surface 24 and the outer surface 26 are concentric arc surfaces. In this preferred embodiment, the radius of the arc of the inner surface 24 is 5080 mm. Of course, the arc radius of the inner surface 24 can also be set to other values. Preferably, it is set to a radius value that is convenient for bending and forming. The arc of the transparent cover 16 is set to be greater than 2 degrees and less than 3 degrees. Specifically, the arc of the transparent cover 16 is set to 2.53 degrees.

The transparent cover 16 and the touch film 22 are bonded by a first optical glue 28, and the touch film 22 and the display screen 18 are bonded by a second optical glue 30. In actual manufacturing, special equipment can be used to affix the touch film 22 to the transparent cover 16 according to the extended arc of the transparent cover 16 through the first optical glue 28 to ensure that the thickness of the first optical glue 28 is consistent, thereby ensuring The extension path of the touch film 22 is parallel to the extension path of the transparent cover 16. Then, the display screen 18 is bonded to the touch film 22 through the second optical glue 30. The first optical glue 28 ensures the light transmission between the transparent cover 16 and the touch film 22, the second optical glue 30 ensures the light transmission between the touch film 22 and the display screen 18, and the first optical glue 28 and the second optical glue 28 The optical glue 30 makes the fixing between the transparent cover 16, the touch film 22 and the display 18 more firm and reliable.

Further, between the transparent cover plate 16 and the touch film 22 and adjacent to the outer periphery of the touch film 22, there is a first reinforcing glue 32 that is opaque, and the first reinforcing glue 32 surrounds the first optical glue 28. In this way, light is shielded and reinforced between the transparent cover 16 and the touch film 22, which makes the touch more sensitive and the structure stronger.

A second reinforcing glue 34 that does not transmit light is provided between the touch film 22 and the display screen 18 and adjacent to the outer periphery of the touch film 22. The second reinforcing glue 34 surrounds the second optical glue 30. The second reinforcing glue 34 shields and strengthens the space between the touch film 22 and the display screen 18, which further makes the touch more sensitive and the structure stronger.

The display assembly 14 also includes a mounting bracket 36 for mounting the display assembly 14 on the main body 12 of the refrigerator door 10, the mounting bracket 36 is fixedly connected to the display device, and the mounting bracket 36 is also fixed to the transparent through tape or other reinforcing glue. On the cover plate 16, the attachment between the mounting bracket 36 and the transparent cover plate 16 is more firm and reliable. Further, the mounting bracket 36 is locked to the foamed main body 12 through a screw structure. Of course, other connection structures can also be adopted between the mounting bracket 36 and the main body 12.

It should be understood that although this specification is described in accordance with the implementation manners, not each implementation manner only includes an independent technical solution. This narration in the specification is only for clarity, and those skilled in the art should regard the specification as a whole. The technical solutions in the embodiments can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

The series of detailed descriptions listed above are only specific descriptions of feasible implementations of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementations or implementations made without departing from the technical spirit of the present invention All changes shall be included in the protection scope of the present invention.
