[0031] like Figure 1-Figure 2 As shown, in one or more embodiments, the mounting housing 10 includes a first housing 11. The first housing 11 can be made of a suitable resin material (such as ABS, PP, etc.) by injection molding. A mounting groove 111 for mounting the display screen 20 is formed on the first housing 11. Figure 1As shown, the mounting groove 111 is a rectangle extending roughly in the left-right direction. Alternatively, the mounting groove 111 may also be a square, a circle or other suitable shapes, as long as it can match the display screen 20. In one or more embodiments, the mounting shell 10 also includes a second shell (not shown in the figure) connected to the first shell 11. The second shell is used to install the first shell 11, and may be, but is not limited to, a door body of a household appliance (not shown in the figure). The second shell may also be formed by injection molding of a suitable resin material (such as ABS, PP, etc.). The fixing method between the first shell 11 and the second shell includes, but is not limited to, screw connection, clamping, etc.

[0032] Continue to see Figure 1 In one or more embodiments, the first housing 11 includes a first vertical wall 11a and a second vertical wall 11b that are arranged opposite to each other. The first vertical wall 11a and the second vertical wall 11b together define a mounting groove 111 for mounting the display screen 20. Alternatively, the mounting groove 111 may also be formed by opening a through hole on the first housing 11. Figure 1 In the orientation shown, the first vertical wall 11a is located on the left side and the second vertical wall 11b is located on the right side. Alternatively, it can also be arranged that the first vertical wall 11a is located on the right side and the second vertical wall 11b is located on the left side. In one or more embodiments, a flange 112 is also formed on the first shell 11. When the display screen 20 is in the initial position, the flange 112 can abut against the display screen 20 to limit the position of the display screen 20. The flange 112 is formed by the peripheral edge of the mounting groove 111 extending toward the center of the mounting groove 111. Specifically, the flange 112 is formed by the edges of the first vertical wall 11a and the second vertical wall 11b close to the outside extending into the mounting groove 111. It should be noted that when the display screen assembly 1 is installed on a household appliance, the outer edges of the first vertical wall 11a and the second vertical wall 11b are flush with other exterior surfaces of the household appliance.

[0033] Continue to see Figure 1 and Figure 2 In one or more embodiments, a stop wall 113 is further formed on one side (i.e., the rear side) of the first shell 11 away from the mounting groove 111. The stop wall 113 extends from the first vertical wall 11a to the second vertical wall 11b. In one or more embodiments, the stop wall 113, the first vertical wall 11a, and the second vertical wall 11b can be integrally formed by injection molding using a suitable resin material (e.g., PE, PVC, etc.) to simplify the manufacturing process. The provision of the stop wall 113 can improve the structural strength of the first shell 11 and can also limit the flipping position of the display screen 20.

[0034] Figure 3 is a structural schematic diagram of an embodiment of a display screen assembly of the present invention in which the display screen is located at an initial position; Figure 4FIG. 2 is a schematic diagram of the structure of an embodiment of the display screen assembly of the present invention in which the display screen is in a flip position. Figure 1-Figure 4 As shown, in one or more embodiments, the display screen 20 is rotatably fixed to the mounting housing 10 and has a relative initial position and a flip position. Figure 3 As shown, when the display screen 20 is in the initial position, it covers the mounting groove 111. At this time, the display screen 20 is in a vertical state and rests on the flange 112, so that the display screen assembly 1 has a complete appearance, improving the integrity and aesthetics of the display screen assembly 1. Figure 4 As shown, when the display screen 20 is in the flip position, the display screen 20 forms a predetermined angle α with the mounting groove 111. That is, the display screen 20 forms a predetermined angle α with the vertical direction. The setting of the flip position can adjust the angle between the user's line of sight and the display screen, which is convenient for the user to operate and view the display screen in a standing position, thereby improving the user's viewing effect of the display screen. In one or more embodiments, the predetermined angle α is 5°-20°. Alternatively, the predetermined angle α can also be set to other suitable angles according to the needs of the user. In one or more embodiments, when the display screen 20 is in the flip position, the display screen 20 is positioned in the first shell 11 and is located between the flange 112 and the stop wall 113, thereby effectively protecting the display screen 20. Alternatively, when the display screen 20 is in the flip position, the display screen 20 can also be positioned outside the first shell 11.

Figure 1 In the orientation shown, the mounting bracket 22 is located below the display panel cover 21, and the rotation axis 221 is formed on the upper side of the mounting bracket 22. Alternatively, the mounting bracket 22 may also be located above the display panel cover 21, and the rotation axis 221 may be formed on the lower side of the mounting bracket 22.

[0037] Continue to see Figure 1-Figure 4 In one or more embodiments, a reinforcing rib 222 is further formed on the mounting bracket 22. The reinforcing rib 222 extends along the length direction of the mounting bracket 22. The provision of the reinforcing rib 222 can improve the structural strength of the mounting bracket 22 and can also improve the stability of the rotation of the display screen 20. In one or more embodiments, the reinforcing rib 222 has a substantially T-shaped vertical cross-section. The T-shaped provision can shield the wire harness connected to the display screen 20, etc., and improve the neatness and aesthetics of the structure. In one or more embodiments, a plurality of mutually spaced upper grooves 2221 are formed on one side (i.e., the upper side) of the reinforcing rib 222 close to the rotation axis 221. The provision of the upper groove 2221 can avoid the rotation lug 212 of the display panel 10. In one or more embodiments, a plurality of mutually spaced lower grooves 2222 are formed on one side (i.e., the lower side) of the reinforcing rib 222 away from the rotation axis 221. The provision of the lower groove 2222 can allow a wire harness tie (not shown in the figure) to pass through it to fix and limit the wire harness.

[0038] In one or more embodiments, the drive device 30 is fixed on the mounting housing 10. Specifically, the drive device 30 can be fixed on the second housing. Alternatively, the drive device 30 can also be arranged at other suitable positions of the mounting housing 10.

Figure 5As shown, in one or more embodiments, the driving device 30 includes a driving motor 31 and a motor mounting seat 32. The driving motor 31 can be but is not limited to a servo motor, a stepping motor, etc. The driving motor 31 has a driving shaft 311 that is roughly parallel to the rotating shaft 221. The driving shaft 311 is connected to the connecting rod structure 40 and is used to drive the connecting rod mechanism 40 to rotate. The motor mounting seat 32 is fixed to the mounting shell 20. A accommodating cavity 321 for placing the driving motor 31 is formed in the motor mounting seat 32. A limiting protrusion 322 is also formed on the motor mounting seat 32. The limiting protrusion 322 has a roughly arc shape. The limiting protrusion 322 is formed on one side of the driving shaft 311 of the driving motor 31. The limiting protrusion 322 can match the first limiting wall 4131 and the second limiting wall 4132 in the connecting rod mechanism 40 to limit the position of the display screen 20. As shown Figure 2 As shown, in one or more embodiments, wire clamping grooves 323 are formed on both sides of the accommodating cavity 321 of the motor mounting seat 32. The arrangement of the wire clamping grooves 323 can conveniently fix the wire harness connected to the driving motor 31.

A fixing protrusion 412 inserted into the fixing hole 421 of the second link 42 is formed on the second end 41b. The fixing protrusion 412 is formed by extending from the first end 41a in a direction away from the first link 41. In one or more embodiments, the fixing protrusion 412 and the sleeve 411 are respectively located on the left and right sides of the first connecting rod 41. Alternatively, the fixing protrusion 412 can also be arranged in the same direction as the sleeve 411, that is, both are arranged on the left or right side of the first connecting rod 41, as long as they can be rotatably connected to the second connecting rod 42.

[0040] Continue to see Figure 1-Figure 6In one or more embodiments, a limiting groove 413 is formed on the first connecting rod 41. The limiting protrusion 322 can be inserted into the limiting groove 413 and has a relative first locking position and a second locking position. In one or more embodiments, a first limiting wall 4131 and a second limiting wall 4132 spaced apart from each other along its circumference are formed on the sleeve 411. The first limiting wall 4131 and the second limiting wall 4132 together define the limiting groove 413. The first limiting wall 4131 and the second limiting wall 4132 extend from the sleeve 411 in a direction away from the central axis, respectively. Based on Figure 6 In the orientation shown, the first limiting wall 4131 is located on the left side, and the second limiting wall 4132 is located on the right side. Alternatively, it can also be arranged that the first limiting wall 4131 is located on the right side, and the second limiting wall 4132 is located on the left side. Figure 3 As shown, when the limiting protrusion 322 is in the first locking position, the first limiting wall 4131 abuts against the limiting protrusion 322, and the display screen 20 is in the initial position. Figure 4 As shown, when the limiting protrusion 322 is in the second locking position, the second limiting wall 4132 abuts against the limiting protrusion 322, and the display screen 20 is in the flipped position.

[0041] like Figure 1-Figure 6 As shown, in one or more embodiments, the second connecting rod 42 is connected to the display screen 20. A fixing hole 421 is formed at one end of the second connecting rod 42 connected to the first connecting rod 41. The fixing hole 421 is a through hole formed on the second connecting rod 42. Alternatively, the fixing hole 421 can also be set as a groove, etc., as long as it can accommodate the fixing protrusion 412 to rotate therein. In one or more embodiments, a connecting plate 422 is formed on one end of the second connecting rod 42 spaced from the fixing hole 421. The connecting plate 422 is a substantially rectangular flat plate extending in the same direction as the display screen 20.
