[0042] Example 1

[0043] likeFigure 1 , Figure 2 As shown in Figure 2 , the present invention provides a display fixing structure for a household appliance door body, including a bracket body 210 fixed to one side of a foamed door body assembly 100. The bracket body 210 includes a fixed bracket 212 and an extended bracket. Among them,

[0044] The fixed bracket 212 is a frame structure, and the display screen 220 of the display screen assembly 200 is fixed within the frame of the fixed bracket 212;

[0045] The fixed bracket 212 is connected to at least one extended bracket to form an installation structure that matches the foamed door body assembly 100. Change the number of extended brackets and / or change the size of one or several extended brackets to change the size of the bracket body 210.

[0046] It should be understood that the installation structure of the foamed door body assembly 100 described above includes changing the size of the bracket body 210 to form different installation structures for cooperating with the foamed door body assembly 100.

[0047] In one embodiment, the fixed bracket 212 and the extended bracket are spliced with each other, which is easy to disassemble.

[0048] In one embodiment, the fixed bracket 212 and the extended bracket are seamlessly connected, and the fixed bracket 212 and the extended bracket are closely abutted against each other, and it is not easy to shake. In order to avoid the existence of a gap between the fixed bracket 212 and the extended bracket, which affects the subsequent bonding of the glass panel 230 of the display screen assembly 200.

[0049] The splicing methods include horizontal splicing, vertical splicing or a combination of both. Several extended brackets are the same or different from each other; that is, the structures between several extended brackets can be the same or different, and the sizes can be the same or different, depending on production requirements.

[0050] In one embodiment, several extended brackets are connected to form a whole and then connected to the fixed bracket 212.

[0051] In one embodiment, a plurality of extension brackets and a fixed bracket 212 are longitudinally spliced in sequence. By changing the size of any one or several of the remaining extension brackets and / or changing the number of extension brackets, the longitudinal size of the bracket body 210 formed by longitudinally splicing the plurality of brackets in sequence can be changed. Similarly, the transverse size of the bracket body 210 formed by transversely splicing a plurality of extension brackets and a fixed bracket 212 in sequence can be changed. In one embodiment, the transverse sequential splicing connection and the longitudinal sequential splicing connection are combined to form the bracket body 210. By changing the size of any one or several extension brackets and / or changing the number of extension brackets, the longitudinal size and / or transverse size of the bracket body 210 can be changed. That is, during actual production, when the size of the display screen 220 remains unchanged, the size of the fixed bracket 212 remains unchanged and there is no need for re-production; if it is necessary to meet the requirements of household appliance door bodies with different sizes, the size of any one or several extension brackets and / or the number of extension brackets can be changed. Moreover, the splicing connection is easy to disassemble. The extension bracket has a simple structure, a short production process, and a low replacement cost, which is convenient for adjusting the size of the bracket body 210.

[0052] As Figure 6 shown, the fixed bracket 212 and the plurality of extension brackets are in the same plane as the outer contour of the glass panel 230 of the display screen assembly 200 facing towards; as Figure 3 shown, the fixed bracket 212 and the plurality of extension brackets are in the same plane as the outer contour of the glass panel 230 of the display screen assembly 200 facing away from. That is, the front and back surfaces of the bracket body 210 are flat, which is beneficial to the engagement between the bracket body 210 and the door panel body 120 of the foam door body assembly 100 and the bonding between the glass panel 230 and the bracket body 210. In one embodiment, the outer surface contour of one side of the bracket 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 body assembly 100 to stably fix the glass panel 230.

[0053] In one embodiment, the fixed bracket 212 and the extension bracket are connected by a buckle. The buckle is engaged with a slot, and the fixed bracket and the extension bracket or between the plurality of extension brackets are detachable.

[0054] In one embodiment, the fixed bracket 212 and the extension bracket are connected by a fastener. The fixed bracket and the extension bracket or between the plurality of extension brackets are fixedly connected, and the connection is stable. Further, the fastener is a screw.

[0055] As Figure 1 、 Figure 2As shown, the fixed bracket and the extension bracket or several extension brackets that are spliced and connected are fixedly connected through the connection structure 218 to form a stable bracket body 210, which is convenient for the subsequent installation of the household appliance door body. In an embodiment, the connection structure 218 includes a first connection portion 2181 and a second connection portion 2182 that are mutually engaged. The first connection portion 2181 and the second connection portion 2182 are respectively arranged on opposite outer walls of two brackets that are spliced and connected. The first connection portion 2181 is a positioning protrusion, and the second connection portion 2182 is a positioning groove that restricts the movement of the first connection portion 2181 in at least four directions. The cross-sections of the first connection portion 2181 and the second connection portion 2182 are both trapezoidal. The first connection portion 2181 and the second connection portion 2182 are respectively provided with through holes. The second connection portion 2182 in the form of a positioning groove is provided with a side wall along the extension direction of the extension bracket to form a side wall structure for the through hole. Further, the extended side wall is flush with one surface of the extension bracket. The first connection portion 2181 and the second connection portion 2182 are fixedly connected by screws in the direction facing or facing away from the glass panel 230. The first connection portion 2181 and the second connection portion 2182 play the roles of positioning and fixing at the same time, and do not affect the flatness of one side of the bracket body 210 facing or facing away from the glass panel 230. Further, the first connection portion 2181 in the form of a positioning protrusion gradually expands along its extension direction, and the second connection portion 2182 in the form of a positioning groove is an opening on the side away from or close to the door panel body. The first connection portion 2181 is placed into the second connection portion 2182 in the form of a positioning groove from the opening of the second connection portion 2182. The first connection portion 2181 is not easily separated from the second connection portion 2182, which is convenient for subsequent fixing by screws. In an embodiment,

[0056] Further, the fixed bracket 212 and the connected extension bracket are abutted through the positioning groove and the positioning protrusion. In an embodiment, as Figure 1 、 Figure 3 shown, the fixed bracket 212 and the connected extension bracket are first pre-assembled and limited by abutment to reduce the assembly difficulty. Further, they are abutted through the positioning groove and the positioning protrusion. The positioning protrusion gradually narrows along its extension direction. In an embodiment, the cross-section of the positioning groove and the cross-section of the positioning protrusion are both triangular. The triangular tip of the positioning protrusion first extends into the positioning groove until the outer contour of the part of the positioning protrusion extending into the positioning groove is in close contact with the inner contour of the positioning groove. Since the triangular tip of the positioning protrusion has a small volume, it can be quickly extended into the positioning groove, and finally the positioning pre-assembly is realized. 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. In an embodiment, as Figure 1As shown, the bracket body 210 includes three brackets that are longitudinally spliced and connected in sequence. That is, the number of extended brackets is two, including the first extended bracket 211 and the second extended bracket 213. That is, the bracket body 210 includes the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213 that are longitudinally spliced and connected in sequence. The display screen 220 is fixed within the fixed bracket 212 having a frame structure. Increase or decrease the first extended bracket 211 and / or the second extended bracket 213; or change the dimensions of the first extended bracket 211 and / or the second extended bracket 213 to change the longitudinal dimension of the bracket body 210. Further, the producer can set several conventional dimensions of the bracket body 210. That is, the bracket body 210 includes the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213 that are spliced and connected in sequence; or the bracket body 210 includes the first extended bracket 211 and the fixed bracket 212 that are spliced and connected in sequence; or the bracket body 210 includes the fixed bracket 212 and the second extended bracket 213 that are spliced and connected in sequence; or the bracket body 210 includes the fixed bracket 212. By increasing or decreasing the first extended bracket 211 and / or the second extended bracket 213, quickly expand the dimension of the bracket body 210 according to production requirements. Further, the first extended bracket 211 and the second extended bracket 213 may be the same or different.

[0057] In an embodiment, as Figures 1 to 3 shown, the first extended bracket 211 is provided with a fifth abutting portion 2111 on the outer wall facing the fixed bracket 212, and the second extended bracket 213 is provided with an eighth abutting portion 2131 on the outer wall facing the fixed bracket 212. The two outer walls of the fixed bracket 212 are provided with a sixth abutting portion 2121 and a seventh abutting portion 2122 that respectively abut against the fifth abutting portion 2111 and the eighth abutting portion 2131. Further, the fifth abutting portion 2111 and the eighth abutting portion 2131 are positioning protrusions, which are triangular; the sixth abutting portion 2121 and the seventh abutting portion 2122 are positioning grooves respectively matching the fifth abutting portion 2111 and the eighth abutting portion 2131, which are triangular.

[0058] Further, the top end and / or the bottom end 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 to 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 foamed door body assembly 100 and stabilize the splicing connection between several brackets. As shown in the figure, the mounting portion 217 is arranged at the bottom end of the bracket body 210 to be fixedly connected to the lower end cover body 130.

[0059] In an embodiment, as Figure 4 、 Figure 5As shown, the bracket body 210 abuts against the upper end cover body 110 and the lower end cover body 130. Further, it abuts against the positioning groove through the positioning protrusion. The positioning protrusion extends into the positioning groove and is positioned by the positioning groove to achieve the splicing connection between adjacent brackets, or to achieve the positioning connection of the upper end cover body 110 and the lower end cover body 130 to the top and bottom ends of the bracket body 210 respectively.

[0060] As Figures 4 to 6 shown, the positioning protrusion gradually narrows along its extending direction. In one embodiment, the cross-section of the positioning groove and the cross-section of the positioning protrusion are both triangular. The triangular tip of the positioning protrusion first extends into the positioning groove until the outer contour of the part of the positioning protrusion extending into the positioning groove closely adheres to the inner contour of the positioning groove; since the triangular tip of the positioning protrusion has a small volume, it can quickly extend into the positioning groove and finally achieve positioning pre-installation.

[0061] 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.

[0062] As Figure 6As shown, in one embodiment, the upper end 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 a third abutting portion 215 at the top end of the bracket body 210; the lower end cover body 130 is provided with a second abutting portion 1311 for abutting against a 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. Insert the first abutting portion 1125 of the upper end cover body 110 into the third abutting portion 215 at the top end of the bracket body 210, and wrap the second abutting portion 1311 of the lower end cover body 130 around the fourth abutting portion 216 at the bottom end of the bracket body 210 to perform pre-positioning of the top and bottom ends of the bracket body 210 and restrict the longitudinal movement of the bracket body 210. In addition, due to the cooperation of the positioning groove and the positioning protrusion, the lateral movement of the bracket body 210 is further restricted. The mounting portion 217 protrudes from the lower end of the bracket body 210, and the mounting portion 217 extends into a groove at the corresponding mounting position of the lower end cover body 130. Screws are sequentially passed through the mounting holes in the groove at the mounting position of the lower end cover body 130 and the mounting holes on the mounting portion 217 to fixedly connect the bracket body 210 and the lower end cover body 130 to restrict 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. The bracket body 210 is engaged with a first limiting portion 1221 provided correspondingly on the door panel body 120 from the side where the top end 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 end of the bracket body 210, and the first cover body 111 and the second cover body 112 are fixedly connected by screws to restrict the upward longitudinal movement of the bracket body 210.

[0063] In one embodiment, two opposite sides of the bracket body 210 are engaged with a first limiting portion 1221 protruding from one surface of the door panel body 120 of the foam door assembly 100.

[0064] As Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, at least one engaging structure 214 is respectively provided on two opposite sides of the bracket body 210 to be engaged with the first limiting portion 1221 on the door panel body 120. Further, at least one engaging structure 214 is respectively provided on two opposite sides of the fixing bracket 212 to stably position the fixing bracket 212 on the door panel body 120 so that it is not easily separated from the door panel body 120, thereby protecting the display screen 220. Further, at least one engaging structure 214 is respectively provided on two opposite sides of the fixing bracket 212 and a plurality of extension brackets to stably position the bracket body 210 on the door panel body 120.

[0065] The snap - fit structure 214 includes a snap - in part 2141 and a second limiting part 2142; the snap - in part 2141 extends into the cavity formed by the first limiting part 1221 with a bent structure and the thin plate surface of the door panel body 120. The bending directions of the first limiting parts 1221 on both sides of the bracket body 210 are opposite to limit the lateral movement of the bracket body 210 and the movement in the direction away from the door panel body 120; the second limiting part 2142 abuts against the outer wall of the first limiting part 1221 to limit the snap - in part 2141 from detaching from the first limiting part 1221, achieving snap - fit. In an embodiment, the number of snap - fit structures 214 on the outer walls of two opposite sides of the bracket body 210 is several, and the structures or sizes of several snap - fit structures 214 on the same side wall of the bracket body 210 can be the same or different from each other.

[0066] As Figures 1 to 3 shown, in an embodiment, the bracket body 210 includes a first extended bracket 211, a fixed bracket 212, and a second extended bracket 213 that are longitudinally spliced and connected in sequence; the number of snap - fit structures 214 is six, and one snap - fit structure 214 is provided on each of the two sides of the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213. The structures and sizes of the first snap - fit structure 2143, the second snap - fit structure 2144, and the third snap - fit structure 2145 on the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213 are slightly different, but the snap - fit effects of the first snap - fit structure 2143, the second snap - fit structure 2144, and the third snap - fit structure 2145 on the corresponding first limiting parts 1221 are the same.

[0067] Further, after several snap - in parts 2141 respectively extend into the cavities formed by the corresponding first limiting parts 1221 and the thin plate surface of the door panel body 120, the corresponding second limiting parts 2142 just abut against the outer walls of the corresponding first limiting parts 1221, so that several first limiting parts 1221 on the door panel body 120 simultaneously exert a force on the bracket body 210 towards the second limiting part 2142, achieving a stable snap - fit.

[0068] The snap - in part 2141 has a gradually narrowing and thinning structure in the direction away from the second limiting part 2142, so that the snap - in part 2141 can smoothly extend into the cavity formed by the first limiting part 1221 and the thin plate surface of the door panel body 120, facilitating quick snap - fit.

[0069] Furthermore, there is an assembly gap between the outer wall of the clamping portion 2141 of the bracket body 210 and the inner wall corresponding to the first limiting portion 1221, so that the clamping portion 2141 can smoothly extend into the cavity formed between the first limiting portion 1221 and the thin plate surface of the door panel body 120. The clamping structure 214 can move slightly left and right in the cavity formed between the corresponding first limiting portion 1221 and the thin plate surface of the door panel body 120, which is convenient for clamping and does not affect the function of the first limiting portion 1221 to restrict the lateral movement of the bracket body 210 and the movement in the direction away from the door panel body 120.

[0070] As Figure 1 , Figure 2 , Figure 6 shown, at least two opposite inner walls of the frame of the fixed bracket 212 are convexly provided with abutting portions 2123 for abutting against the back surface of the display screen 220, and the thickness of the abutting portion 2123 is less than the thickness of the frame of the fixed bracket 212. The outer contour of the abutting portion 2123 and the outer contour of the display screen 220 are both located within the corresponding bracket frame. In an embodiment, the cross-section of the display screen 220 and the inner contour of the bracket frame for fixing the display screen are both rectangular; one end of each of the two inner walls of the frame of the fixed bracket 212 is provided with an abutting portion 2123, and an abutting portion 2123 is respectively provided near the corners of the other two inner walls of the frame of the fixed bracket 212.
