The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

In the various drawings of the present invention, certain dimensions of structures or portions are exaggerated relative to other structures or portions for ease of illustration and, therefore, are used only to illustrate the basic structure of the subject matter of the present invention.

In the description of the embodiments of the present invention, the terms "front", "back", "upper", "lower", "left", "right", etc. indicate orientations or positional relationships, and all refer to the orientation of the door body of the refrigeration equipment and the orientation of the refrigeration equipment relative to a user during normal use.

As shown in fig. 1, the present invention provides a refrigeration unit door body 10, which includes a door shell 11 and a frame assembly 12.

The door shell 11 is a vertically arranged plate body.

The frame assembly 12 is disposed at a side of the door case 11, and may be disposed at a left side of the door case 11 or a right side of the door case 11 according to specific situations. For example, when the refrigeration device door 10 is applied to a double-door refrigerator, the frame assembly 12 of the left refrigeration device door 10 is disposed on the left side of the door shell 11, and the frame assembly 12 of the right refrigeration device door 10 is disposed on the right side of the door shell 11.

As shown in fig. 2 and 3, the frame assembly 12 includes a side frame 121, a decoration 123 and a fixing strip 122. The side frame 121 is a main body of the frame assembly 12, and the side frame 121 is located behind the side edge of the door shell 11. The door body of the side frame 121 is partially covered by the door shell 11, and partially exposed to the door shell 11, and the space between the door shell 11 and the side frame 121 is a foaming space for filling the foaming material into the refrigeration device door body 10. In the present invention, the inner side of the side frame 121 refers to the side facing the foaming space, and the outer side refers to the side facing away from the foaming space.

The decoration 123 is located outside the side frame 121, and the fixing strip 122 is located inside the side frame 121. The decoration 123 plays a role of decoration, improves the appearance effect of the refrigeration equipment door body 10, and can improve the overall strength of the frame assembly 12.

One of the fixing strip 122 and the decoration 123 has a connection structure 124 penetrating the side frame 121, and the other has a fitting structure fitting the connection structure 124, and the connection structure 124 penetrates the side frame 121 and is fitted with the fitting structure to fix the decoration 123 and the fixing strip 122 to the side frame 121 in the lateral direction.

A fixing strip 122 is provided on the inner side of the side frame 121, and the position of the decoration 123 is fixed by a connecting structure 124 and a fitting structure passing through the side frame 121. The invention avoids the assembly of the decoration 123 and the side frame 121 made of metal materials, thereby reducing the difficulty of the assembly of the decoration 123. Since the side frame 121 is not directly assembled with the connection structure 124, the deformation of the side frame 121 due to the extrusion of the connection structure 124 during the assembly process is prevented.

Further, the side frame 121 is made of metal, and the decoration 123 is made of aluminum alloy. The fixing strip 122 is made of plastic, and the fixing strip 122 made of plastic is low in cost and easy to assemble.

In one embodiment of the present invention, the connecting structure 124 is disposed on the fixing strip 122 and the mating structure is disposed on the trim 123.

In order to improve the decoration effect of the decoration 123, the length of the decoration 123 in the longitudinal direction is not less than three-fourths of the side frame 121, and in order to ensure that the decoration 123 with a long length has a good fixing effect, the length of the fixing strip 122 in the longitudinal direction is not less than three-fourths of the side frame 121, and the connecting structures 124 are plural and arranged in the longitudinal direction.

As shown in fig. 4 and 5, preferably, the side frame 121 is provided with an upper positioning hole 1211 and a lower positioning hole 1212 located below the upper positioning hole 1211, and the fixing strip 122 has an upper positioning column 1221 matching with the upper positioning hole 1211 and a lower positioning column 1222 matching with the lower positioning hole 1212. When assembling the side frame 121 and the fixing bar 122, the fixing bar 122 is positioned by engaging the upper positioning posts 1221 with the upper positioning holes 1211 and engaging the lower positioning posts 1222 with the lower positioning holes 1212.

The connecting structure 124 and the mating structure are further described in conjunction with fig. 4, 5, 6, and 7.

The connecting structure 124 has a support 1241 protruding out of the fixing bar 122 and a connecting member 1242 extending upward from the top of the support 1241. The inside cooperation chamber 1231 that has longitudinal extension of ornamental 123, and the cooperation mouth 1232 with cooperation chamber 1231 intercommunication is seted up towards one side of side frame 121 to ornamental 123, and cooperation mouth 1232 constitutes the cooperation structure with cooperation chamber 1231. When the connecting structure 124 and the mating structure are mated, the connecting member 1242 is inserted into the mating cavity 1231, and the top of the supporting member 1241 supports the inner wall of the top of the mating opening 1232.

Preferably, the number and location of the fitting holes 1232 correspond one-to-one to the connecting structures 124. The number of the fitting cavities 1231 is one and all the fitting ports 1232 communicate with the fitting cavities 1231, thereby simplifying the structure.

When assembling the frame assembly 12, the fixing bars 122 are first placed on the inner side of the side frame 121, and the connecting structures 124 are then passed through the side frame 121. Then, the decoration 123 is placed at a position where the connecting piece 1242 corresponds to the matching opening 1232, then the decoration 123 and the side frame 121 are relatively moved transversely until the connecting piece 1242 passes through the matching opening 1232, and finally the decoration 123 is moved downwards, so that the connecting piece 1242 is assembled with the matching cavity 1231, and the assembly of the decoration 123 is completed. The operation of assembling the frame component 12 is simple and convenient, and the reliability of the assembled frame component 12 is high, and the decorating part 123 is not easy to fall off from the side frame 121.

Preferably, the connecting member 1242 has a guiding structure with an inner wall of the fitting cavity 1231, the guiding structure includes a guiding strip 12311 and a guiding groove 12421 fitted with the guiding strip 12311, and both the guiding strip 12311 and the guiding groove 12421 extend in a longitudinal direction. During the process of assembling the frame assembly 12, the guide grooves 12421 are engaged with the guide bars 12311 to position and guide the longitudinal movement of the fixing bars 122 and the side frames 121 opposite to the decorative pieces 123, so as to ensure that the connecting members 1242 are accurately engaged with the engagement cavities 1231. Specifically, the guide grooves 12421 are provided on the connection members 1242, and the guide strips 12311 are provided on the inner wall of the fitting cavity 1231.

In one embodiment of the present invention, the side frame 121 is provided with a window 1213 through which the connection structure 124 passes. The mating opening 1232 and the window 1213 each have a length in the longitudinal direction that is greater than the length of the connecting structure 124 in the longitudinal direction, thereby facilitating passage of the connecting structure 124 through the window 1213 and the mating opening 1232. Also, since the side frames 121, the fixing strips 122, and the decoration 123 are long in the longitudinal direction, and precision control is difficult, if there is a certain deviation in the position of the connecting structure 124 with respect to the windows 1213 and the coupling ports 1232, the large windows 1213 and the coupling ports 1232 can ensure that the connecting structure 124 can pass through the windows 1213 and the coupling ports 1232.

The side frame 121 has a side plate 1215 positioned at a side of the door case 11 and a front plate 1214 connected to a front side of the side plate 1215 and positioned at a rear of the door case 11, and a window 1213 is provided in the front plate 1214. The fixing strip 122 has a first abutting surface 1223 abutting against the inner side of the side plate 1215 and a second abutting surface 1224 abutting against the inner side of the front plate 1214, when the connecting structure 124 is assembled with the assembling structure, the first abutting surface 1223 of the fixing strip 122 abuts against the inner side of the side plate 1215, and the second abutting surface 1224 abuts against the inner side of the front plate 1214, so that the stability of the fixing strip 122 is improved.

Further, the first abutting surface 1223 and the second abutting surface 1224 each have an inward recessed overflow preventing groove 1225. When the refrigeration device door body 10 performs foaming operation, the overflow-preventing groove 1225 can accommodate the foaming material overflowing from between the fixing strip 122 and the side frame 121, so that the foaming material is prevented from overflowing from a gap between the fixing strip 122 and the side frame 121, and the foaming material is effectively prevented from overflowing from the window 1213 to the surface of the refrigeration device door body 10.

As shown in fig. 1, in an embodiment of the present invention, the refrigeration appliance door body 10 further includes a decoration strip assembly 13 disposed at the bottom of the door shell 11. The inner side of the molding member 13 constitutes a bottom wall of the foaming space.

As shown in fig. 8, the molding assembly 13 includes an end cap 131 and a lower molding 132, and the end cap 131 is mounted on the bottom of the lower molding 132. The side frame 121 is located at a side of the end cap 131, a front bending plate 1216 bent toward a side surface of the end cap 131 is provided at a front side of the side frame 121, a bottom bending plate 1217 extending in a left-right direction is provided at a bottom portion thereof, the end cap 131 is provided with a receiving groove 1311 receiving at least a part of the front bending plate 1216 and the bottom bending plate 1217, and a wall of the receiving groove 1311 is provided with a latch 1312 connected to the front bending plate 1216.

When the frame assembly 12 and the molding assembly 13 are assembled, the front bending plate 1216 and the bottom bending plate 1217 of the side frame 121 are inserted into the receiving slot 1311 for positioning, and the positions of the frame assembly 12 and the molding assembly 13 are fixed to each other by the fastener 1312, so that the assembling process is simple and convenient.

The trim 123 has a seal 1233 that closes the space between the front flap 1216 and the side of the end cap 131. The sealing portion 1233 can prevent the foaming material from overflowing from the side surfaces of the front bending plate 1216 and the end cap 131 to the surface of the refrigeration appliance door body 10 when the refrigeration appliance door body 10 is foamed.

Referring to fig. 4, the bottom of the fixing bar 122 has a support plate 1226 extending laterally and supported on the end cap 131. The end cap 131 improves the stability of the fixing bar 122 by supporting the supporting plate 1226. The side frame 121 has a first receiving portion 1218 supported on the supporting plate 1226, the garnish 123 has a second receiving portion 1234 supported on the supporting plate 1226, and a fastener 125 for connecting the supporting plate 1226 and the garnish 123 is fixed to the supporting plate 1226.
