It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] Example 1

[0041] like Figure 1 As shown, the present invention provides a display screen fixing structure for a home appliance door, comprising a bracket body 210 fixed to one side of a foam door assembly 100, the bracket body 210 is a frame structure, and a display screen 220 of the display screen assembly 200 is fixed in the bracket body 210 frame; wherein,

[0042] like Figure 2 , Figure 4 , Figure 5 As shown, the outer walls of the two opposite sides of the bracket body 210 are respectively provided with a snap-in structure 214, which is snap-fitted with the door panel body 120 of the foam door body assembly 100 to fix the bracket body 210 with the display screen 220 installed on the foam door body assembly 100.

[0043] In one embodiment, the bracket body 210 is provided with an abutting portion to abut against the upper end cover body 110 and / or the lower end cover body 130 of the foam door body assembly 100. Specifically, the other two opposite sides of the bracket body 210 are respectively provided with a third abutting portion 215 and a fourth abutting portion 216 to abut against the upper end cover body 110 and the lower end cover body 130 of the foam door body assembly 100, respectively, and the upper end cover body 110 and the lower end cover body 130 are respectively pressed against the top and bottom ends of the bracket body 210 to stabilize the installation of the bracket body 210.

[0044] like Figure 1 , Figure 3 As shown, in one embodiment, the clamping structure 214 includes a clamping portion 2141; the clamping portion 2141 extends into a cavity formed by a first position-limiting portion 1221 with a bent structure provided on the door panel body 120 and a thin plate surface of the door panel body 120, so as to abut against an inner wall of the first position-limiting portion 1221. The bending directions of the first position-limiting portions 1221 located on both sides of the bracket body 210 are opposite to each other, so as to limit the lateral movement of the bracket body 210 and the movement in a direction away from the door panel body 120.

[0045] In one embodiment, the snap-in structure 214 also includes a second limiting portion 2142. The second limiting portion 2142 abuts against the outer wall of the first limiting portion 1221 to limit the snap-in portion 2141 from being separated from the first limiting portion 1221, thereby achieving snap-in engagement. In one embodiment, the number of snap-in structures 214 on the outer walls of the two opposite sides of the bracket body 210 is multiple, and the lengths of the multiple snap-in structures 214 located on the same side wall of the bracket body 210 may be the same or different. Further, after the multiple snap-in portions 2141 are respectively extended into the cavities formed by the corresponding first limiting portions 1221 and the thin plate surface of the door panel body 120, the corresponding second limiting portions 2142 just abut against the outer wall of the corresponding first limiting portion 1221, so that the multiple first limiting portions 1221 on the door panel body 120 simultaneously apply a force toward the second limiting portion 2142 to the bracket body 210, thereby achieving a stable snap-in engagement.

[0046] The snap-in portion 2141 gradually narrows and thins in a direction away from the second limiting portion 2142 , so that the snap-in portion 2141 can smoothly extend into the cavity formed by the first limiting portion 1221 and the thin plate surface of the door panel body 120 , so as to quickly achieve snap-in.

[0047] Furthermore, an assembly gap is provided between the outer wall of the snap-in portion 2141 of the bracket body 210 and the inner wall corresponding to the first limiting portion 1221, so that the snap-in portion 2141 can smoothly extend into the cavity formed by the first limiting portion 1221 and the thin plate surface of the door panel body 120. The snap-in structure 214 can move slightly left and right in the cavity formed by the corresponding first limiting portion 1221 and the thin plate surface of the door panel body 120, which facilitates the snap-in and does not affect the effect of the first limiting portion 1221 on limiting the lateral movement of the bracket body 210 and the movement in the direction away from the door panel body 120.

[0048] In one embodiment, if Figure 2 As shown, the bracket body 210 and the upper end cover body 110 and the lower end cover body 130 are all in contact with the positioning protrusions through the positioning grooves for pressing. The positioning protrusions extend into the positioning grooves and are positioned by the positioning grooves to limit the longitudinal movement of the bracket body 210.

[0049] Furthermore, the positioning protrusion gradually narrows along its extension direction. In one embodiment, the cross-sections of the positioning groove and the positioning protrusion are both triangular, and the triangular corner of the positioning protrusion first extends into the positioning groove until the outer contour of the part where the positioning protrusion extends into the positioning groove is closely attached to the inner contour of the positioning groove; since the triangular corner of the positioning protrusion is small in size, it can be quickly inserted into the positioning groove, and finally positioning pre-installation is achieved.

[0050] The inner contour of the positioning groove wraps the outer contour of the positioning protrusion extending into the positioning groove, so that after the positioning protrusion extends into the positioning groove, it is firmly fixed and will not shake left and right, so that the bracket body 210 cannot move laterally.

[0051] Furthermore, if Figure 2 , Figure 3 As shown, the top and / or bottom of the bracket body 210 is provided with a mounting portion 217, and the mounting portion 217 is provided with a mounting hole to be fixedly connected with the upper end cover body 110 and / or the lower end cover body 130 by screws, so as to further fix the bracket body 210 on the foam door body assembly 100. As shown in the figure, the mounting portion 217 is arranged at the bottom end of the bracket body 210 to be fixedly connected with the lower end cover body 130.

[0052] like Figure 4As shown, in one embodiment, the upper cover body 110 includes a first cover body 111 and a second cover body 112, the second cover body 112 covers the first cover body 111, and the second cover body 112 is provided with a first abutting portion 1125 for abutting against the third abutting portion 215 at the top end of the bracket body 210; the lower cover body 130 is provided with a second abutting portion 1311 abutting against the fourth abutting portion 216 at the bottom end of the bracket body 210. The second abutting portion 1311 and the third abutting portion 215 are positioning grooves, and the first abutting portion 1125 and the fourth abutting portion 216 are positioning protrusions. The first abutment portion 1125 of the upper end cover body 110 is extended into the third abutment portion 215 at the top of the bracket body 210, and the second abutment portion 1311 of the lower end cover body 130 is wrapped around the fourth abutment portion 216 at the bottom of the bracket body 210, and the top and bottom ends of the bracket body 210 are positioned and pre-installed to limit the longitudinal movement of the bracket body 210. In addition, due to the cooperation between the positioning groove and the positioning protrusion, the lateral movement of the bracket body 210 is further limited. The mounting portion 217 is convexly arranged at the lower end of the bracket body 210, and the mounting portion 217 is extended into the groove of the corresponding mounting position of the lower end cover body 130. The nuts or screws are sequentially passed through the mounting holes in the groove of the mounting position of the lower end cover body 130 and the mounting holes on the mounting portion 217 to fix the bracket body 210 and the lower end cover body 130 to limit the downward longitudinal movement of the bracket body 210. The first cover body 111 of the upper end cover body 110 is fixedly connected to the door panel body 120, and the bracket body 210 is engaged with the first limiting portion 1221 corresponding to the door panel body 120 from the side where the top of the door panel body 120 is located. The first abutting portion 1125 of the second cover body 112 abuts against the third abutting portion 215 at the top of the bracket body 210, and the first cover body 111 and the second cover body 112 are fixedly connected by nuts or screws to limit the upward longitudinal movement of the bracket body 210.

[0053] like Figure 1 As shown, at least two opposite inner walls of the frame of the bracket body 210 are convexly provided with a fifth abutting portion 2123 for abutting against the back of the display screen 220, and the thickness of the fifth abutting portion 2123 is less than the thickness of the frame of the bracket body 210. The outer contour of the fifth abutting portion 2123 and the outer contour of the display screen 220 are both located in the frame of the bracket body 210. In one embodiment, the cross section of the display screen 220 and the inner contour of the frame of the bracket body 210 are both rectangular; a fifth abutting portion 2123 is respectively provided at both ends of an inner wall of the bracket body 210, and a fifth abutting portion 2123 is respectively provided near the corners of the frame of the other two inner walls of the bracket body 210, and the four fifth abutting portions 2123 are respectively abutted against the four corners of an outer surface of the display screen 220 to firmly abut the display screen 220.

[0054] like Figure 1As shown, an outer surface contour of the support body 210 facing the glass panel 230 of the display screen assembly 200 is located in the same plane, so that the glass panel 230 of the display screen assembly 200 can be smoothly attached to the outer wall of the support body 210. In one embodiment, an outer surface contour of the support body 210 facing the glass panel 230 of the display screen assembly 200 is flush with the outer contours of the first side trim 150 and the second side trim 160 of the foam door assembly 100, so as to stably fix the glass panel 230.

[0055] like Figure 3 As shown, the outer surface of the bracket body 210 facing the glass panel 230 protrudes from or is flush with the outer surface of the first limiting portion 1221 of the door panel body 120 facing the glass panel 230, so as to prevent the outer surface of the first limiting portion 1221 facing the glass panel 230 from protruding from the outer surface of the bracket body 210 facing the glass panel 230, thereby affecting the fit between the glass panel 230 bonded to the outside of the bracket body 210 and the frame of the foam door body assembly 100 when the display screen assembly 200 is clamped on one side of the foam door body assembly 100.

[0056] like Figure 1 , Figure 2 As shown, the bracket body 210 is provided with a clearance portion 219 on both sides for allowing the clamping structure 214 to be clamped with the first limiting portion 1221. During assembly, the clearance portions 219 on both sides of the bracket body 210 are aligned with the first limiting portion 1221 at the corresponding position on the door panel body 120, and the bracket body 210 moves down for clamping, so that the bracket body 210 and the door panel body 120 are clamped.
