[0038] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0039] In the various drawings of the present invention, for the sake of convenience, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, only the basic structure of the subject matter of the present invention is illustrated.

[0040] In the description of the specific embodiments of the present invention, the terms "longitudinal," "front," and "rear" and other terms indicating directions or positional relationships refer to the orientation of the door or refrigeration unit relative to the user during normal use. For example, the front side refers to the side of the door or refrigeration unit facing the user, and the rear side refers to the side of the door or refrigeration unit facing away from the user.

[0041] like Figures 1 to 12 As shown, the present invention provides a door body 10 , comprising a door panel 110 , an end cover 120 and an aluminum alloy decorative strip 130 .

[0042] See Figure 1 、 Figure 2 and Figure 3 The door panel 110 is a vertically arranged plate body, which constitutes the main body of the door body 10.

[0043] The length direction of the end cover 120 and the aluminum alloy decorative strip 130 are both left-right directions.

[0044] The end cap 120 is disposed behind the door panel 110 and is in contact with the rear side of the door panel 110. For ease of illustration, the preferred embodiment of the present invention shows the end cap 120 disposed at the bottom of the door panel 110. Obviously, the end cap 120 can also be disposed at the top of the door panel 110.

[0045] Aluminum alloy trim strip 130 is mounted on end cap 120. The strong aluminum alloy trim strip 130 and end cap 120 complement each other, enhancing the strength of the assembly formed by the aluminum alloy trim strip 130 and end cap 120 and preventing deformation. Furthermore, the aluminum alloy trim strip 130 is exposed on the door panel 110 for decorative purposes.

[0046] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The front side of the end cap 120 has a first end surface 121 corresponding to the door panel 110 in the front-to-back direction, and a second end surface 122 corresponding to the aluminum alloy decorative strip 130. The door panel 110 and the aluminum alloy decorative strip 130 are located in front of the first end surface 121 and the second end surface 122, respectively. The first end surface 121 of the end cap 120 is used to connect to the door panel 110. The aluminum alloy decorative strip 130 and the door panel 110 are arranged longitudinally, so that the decorative surface of the aluminum alloy decorative strip 130 and the door panel 110 both face forward, improving the user's visual experience.

[0047] See Figure 2 In one embodiment of the present invention, the door body 10 further includes side frames 140 disposed at both ends of the end cover 120 in the length direction. The inner sides of the side frames 140 are in contact with both ends of the end cover 120 in the length direction.

[0048] The front side of the side frame 140 is bent to form a front bent plate 141. The bent plate of the side frame 140 is connected to the first end face 121 of the end cover 120 by fasteners. The fasteners described in the present invention are parts used for fastening connections, such as screws and bolts. The rear side of the side frame 140 can also be connected to the end cover 120 by fasteners, thereby further improving the stability of the connection between the end cover 120 and the side frame 140. The rear side of the door panel 110 is fitted with the front bent plate 141 of the side frame 140, and the door panel 110 can be connected to the front side of the front bent plate 141 and the first end face 121 of the end cover 120 by gluing or other methods.

[0049] When assembling the door body 10, the end cap 120 and the side frame 140 are connected together, and the door panel 110 is placed in front of the end cap 120 and the side frame 140. Then, the area between the door panel 110, the side frame 140, and the end cap 120 is foamed. After the foaming is completed, the aluminum alloy decorative strip 130 is installed on the end cap 120, completing the assembly of the door body 10.

[0050] The following combination Figures 5 to 10The structure and connection method of the end cover 120 and the aluminum alloy decorative strip 130 are described in detail.

[0051] The first end surface 121 of the end cover 120 is forward of the second end surface 122, and the second end surface 122 of the end cover 120 extends longitudinally in a direction protruding out of the door body 10. To clearly illustrate the position of the second end surface 122, the embodiment of the present invention is illustrated as an example in which the end cover 120 is installed at the bottom end of the door panel 110. In this case, the first end surface 121 is located below the door panel 110, and the second end surface 122 faces forward. The aluminum alloy decorative strip 130 is located below the first end surface 121 and forward of the first end surface 121.

[0052] The end cover 120 protrudes longitudinally from the door body 10 in a region behind the first end surface 121 , thereby forming a horizontal third end surface 123 outside the door body 10 .

[0053] The end cap 120 has a receiving groove 124 that corresponds longitudinally to the aluminum alloy trim 130 and is located behind the first end surface 121. The opening of the receiving groove 124 faces the aluminum alloy trim 130. The side of the aluminum alloy trim 130 facing the receiving groove 124 has an embedded structure 131 that extends into the receiving groove 124. The embedded structure 131 cooperates with the receiving groove 124 to limit the aluminum alloy trim 130 in the front-to-back direction and along the length of the aluminum alloy trim 130. The cooperation between the embedded structure 131 and the receiving groove 124 ensures that the end cap 120 and the aluminum alloy trim 130 are seamless when assembled, thereby improving the visual effect of the door body.

[0054] In order to further fix the aluminum alloy trim 130 relative to the end cover 120, a snap-fit portion 125 is provided on the inner wall of the receiving groove 124, and the embedded structure 131 has a snap-fitting portion 1311 adapted to the snap-fitting portion 125. The snap-fitting portion 125 cooperates with the snap-fitting portion 1311 to limit the aluminum alloy trim 130 in the longitudinal direction.

[0055] Specifically, the snap-fit portion 1311 protrudes in the front-to-back direction toward the snap-fit portion 125. The snap-fit portion 125 includes an elastic arm 1251 whose first end is connected to the wall of the receiving slot 124, a first abutting portion 1252 connected to the second end of the elastic arm 1251 and abutting the snap-fit portion 1311 on the side facing the aluminum alloy trim 130, and a second abutting portion 1253 abutting the snap-fit portion 1311 on the end away from the embedded structure 131. The first abutting portion 1252 is used to restrict the embedded structure 131 from longitudinally moving away from the receiving slot 124. The second abutting portion 1253 pushes the snap-fit portion 1311, causing the side of the embedded structure 131 facing away from the snap-fit portion 125 in the front-to-back direction to abut against the wall of the receiving slot 124, thereby achieving a tighter fit between the embedded structure 131 and the receiving slot 124.

[0056] The process of assembling the aluminum alloy trim 130 and the end cover 120 is as follows: move the aluminum alloy trim 130 longitudinally so that the embedded structure 131 extends into the receiving groove 124. During the movement of the aluminum alloy trim 130, the snap-fitting portion 1311 acts on the elastic arm 1251 and the first supporting portion 1252 to deform the elastic arm 1251 until the snap-fitting portion 1311 passes over the elastic arm 1251. At this time, the first supporting portion 1252 and the second supporting portion 1253 abut against the snap-fitting portion 1311, completing the assembly of the aluminum alloy trim 130 and the end cover 120.

[0057] Furthermore, there are a plurality of snap-fit portions 125 , and the plurality of snap-fit portions 125 are evenly distributed along the length direction of the end cover 120 , so as to improve the reliability of the connection between the aluminum alloy decorative strip 130 and the end cover 120 .

[0058] See Figure 7 、 Figure 8 and Figure 9 One of the end cap 120 and the aluminum alloy decorative strip 130 has a slider 126, and the other has a slide groove 132. Both the slider 126 and the slide groove 132 extend longitudinally and fit in the slide groove 132. The end cap 120 and the aluminum alloy decorative strip 130 are assembled longitudinally by the slider 126 and the slide groove 132. The slider 126 and the slide groove 132 can play a role in positioning and guiding when assembling the end cap 120 and the aluminum alloy decorative strip 130.

[0059] The embodiment of the present invention is illustrated by exemplifying a slide groove 132 disposed on an aluminum alloy trim strip 130 and a slider 126 disposed on an end cap 120. Specifically, a forwardly recessed groove is provided on the rear side of the aluminum alloy trim strip 130 to form the slide groove 132. The slide groove 132 extends to the side of the aluminum alloy trim strip 130 facing the receiving slot 124, forming an opening. A protrusion is provided on the front side of the end cap 120 to form the slider 126. The slider 126 extends to the third end face 123 of the end cap 120. When assembling the aluminum alloy trim strip 130 and the end cap 120, the aluminum alloy trim strip 130 and the end cap 120 are moved toward each other longitudinally, so that the slider 126 passes through the opening of the slide groove 132 at one end of the third end face 123. The aluminum alloy trim strip 130 and the end cap 120 are then moved toward each other until the slide groove 132 and the slider 126 are fully engaged.

[0060] Furthermore, the slider 126 and the slide groove 132 are respectively provided at the left or right end of the end cap 120 and the decorative strip 130. Due to the long lengths of the end cap 120 and the decorative strip 130, tolerances exist during production, resulting in a length mismatch between the end cap 120 and the decorative strip 130. Placing the slider 126 and the slide groove 132 at the end ensures that the end cap 120 and the decorative strip 130 are aligned at the end, thus preventing a step from forming at the end of the door body 10 due to the length mismatch between the end cap 120 and the decorative strip 130.

[0061] The rear side of the aluminum alloy decorative strip 130 has a cover plate 133 protruding backwards, and the cover plate 133 is in contact with the outer side of the end cover 120 in the longitudinal direction, that is, the third end surface 123 of the end cover 120 .

[0062] The third end surface 123 of the end cap 120 is provided with a groove for accommodating the cover plate 133. The cover plate 133 can support the end cap 120 when the end cap 120 is subjected to force, preventing the end cap 120 from deforming. In addition, the provision of the groove can align the third end surface 123 of the end cap 120 with the side of the cover plate 133 facing away from the end cap 120 in the longitudinal direction, thereby improving the visual effect.

[0063] The cover plate 133 has a longitudinally protruding insertion strip 1331 on one side facing the end cap 120. The end cap 120 is provided with a slot 127 that matches the insertion strip 1331. The insertion strip 1331 is inserted into the slot 127 to position the cover plate 133 during the assembly of the end cap 120 and the aluminum alloy trim strip 130.

[0064] In order to improve the reliability of the connection between the cover plate 133 and the end cover 120, the cover plate 133 is connected to the end cover 120 through a fastener.

[0065] The structure connecting the aluminum alloy decorative strip 130 to the end cap 120 in the present invention comprises a cover plate 133 and an embedded structure 131. The front side of the aluminum alloy decorative strip 130 is not provided with a structure for connecting to the end cap 120, thereby providing a better decorative effect. The door body 10 of the present invention ensures a stable and reliable connection between the end cap 120 and the aluminum alloy decorative strip 130 while enhancing the visual effect.

[0066] In one embodiment of the present invention, a handle 134 is installed on the rear side of the aluminum alloy decorative strip 130 . The end cover 120 is provided with a handle receiving groove 128 for receiving the handle 134 . The handle receiving groove 128 is located behind the receiving groove 124 .

[0067] A handle mounting window 1332 is longitudinally provided in the cover plate 133. Handle 134 passes through handle mounting window 1332, and the side of handle 134 longitudinally distal from end cap 120 is flush with the side of cover plate 133 longitudinally distal from end cap 120. Handle 134 is connected to end cap 120 along one side of its length via fasteners. Because handle 134 and aluminum alloy trim 130 are mounted together, the connection between end cap 120 and handle 134 reinforces both ends.

[0068] The handle 134 has an L-shaped connector 1341 on the other side along its length. One side of the L-shaped connector 1341 is connected to the rear side of the aluminum alloy trim 130 by fasteners, and the other side is connected to the side of the cover plate 133 toward the end cover 120 body in the longitudinal direction by fasteners, thereby ensuring that the connection between the handle 134 and the cover plate 133 and the aluminum alloy trim 130 is firm and reliable.

[0069] The rear side of the handle 134 is provided with a handle insert 1342 protruding toward the end cover 120, and the end cover 120 is provided with a groove in the handle receiving groove 128 that matches the handle insert 1342. By providing the handle insert 1342, the handle 134 can be prevented from falling off when the handle 134 is pulled forward.

[0070] Furthermore, handle mounting window 1332 extends to the rear side of the cover plate, forming an opening. Aluminum alloy trim 130 has a fixing slot 135 on the rear side, and handle 134 has a fixing block on the front side that mates with the fixing slot. To assemble the handle, insert the handle through the rear opening of the handle mounting window until the fixing block engages with the fixing slot, then tighten the fasteners, making the assembly process simple and convenient.

[0071] The assembly process of the end cap 120 and the aluminum alloy decorative strip 130 is as follows: the aluminum alloy decorative strip 130 is placed on the side of the end cap 120 facing away from the door body 10 in the longitudinal direction. Then, the aluminum alloy decorative strip 130 is moved so that the embedded structure 131 is inserted into the receiving groove 124 and the snap-fit portion 125 is engaged with the snap-fit portion 1311. The insert 1331 of the cover plate 133 is inserted into the slot 127 of the end cap 120, and the handle 134 is inserted into the handle receiving groove 128. Finally, the fasteners connecting the handle 134 to the end cap 120 and the fasteners connecting the cover plate 133 to the end cap 120 are tightened to complete the assembly.

[0072] See Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 In one embodiment of the present invention, the door body 10 further includes a light emitting device 150 located behind the door panel 110 . The light emitting device 150 is received in the receiving groove 124 .

[0073] See Figure 5 and Figure 6 The light-emitting device 150 includes a light-transmitting portion 153, a light guide bar 151, and a light source 152 disposed within the light guide bar 151. The light guide bar 151 is located on the side of the light-transmitting portion 153 facing away from the light-transmitting region 1241. The length of the light guide bar 151 is oriented in the left-right direction. A mounting groove 1511 is disposed within the light guide portion, and the light source 152 is fixedly mounted within the mounting groove 1511. The light-transmitting portion 153 is connected to the side of the light guide bar 151 that faces the aluminum alloy trim strip 130.

[0074] A light-transmitting area 1241 is formed between the rear side of the door panel 110 and the front side of the aluminum alloy decorative strip 130 . The light-transmitting portion 153 corresponds to the light-transmitting area 1241 so that the light of the light-emitting device 150 is irradiated to the front side of the aluminum alloy decorative strip 130 .

[0075] Specifically, the side of the aluminum alloy trim 130 facing the receiving groove 124 is basically flush with the opening of the receiving groove 124, and the opening part of the receiving groove 124 is longitudinally corresponding to the side of the aluminum alloy trim 130 facing the receiving groove 124, and partially protrudes forward from the aluminum alloy trim 130 to form a light-transmitting area 1241 located between the door panel 110 and the aluminum alloy trim 130.

[0076] By setting the light-transmitting area 1241, the light from the light-emitting device 150 is concentrated on the front side of the aluminum alloy decorative strip 130, and the light will not be irradiated to other areas, so that the user's visual experience is better. In addition, the light is irradiated on the surface of the aluminum alloy decorative strip 130 to remind the user of the position of the door body 10, rather than the light directly hitting the user's eyes, which reduces the irritation of the light and further enhances the user's visual effect. In addition, the light from the light-emitting device 150 is irradiated on the aluminum alloy decorative strip, which has a better visual effect than the plastic decorative strip, and the surface of the aluminum alloy can reflect light, which can better remind the user of the position of the door body 10 than the plastic decorative strip.

[0077] The light emitted by the light source 152 is transmitted to the light-transmitting portion 153 through the light guide bar 151 , so the light is soft and does not irritate the user's eyes, thereby improving the user's visual experience.

[0078] Furthermore, one embodiment of the present invention also provides another way for the light emitted by the light source 152 to be transmitted to the light-transmitting portion 153. A gap is provided between the front side of the light guide bar 151 and the front wall of the receiving groove 124, the front side surface of the light-transmitting portion 153 is provided as an inclined surface, and the side of the front side surface of the light-transmitting portion 153 close to the light guide bar 151 is provided at the rear of the side facing away from the light guide bar 151, and a gap is provided between the side of the front side surface of the light-transmitting portion 153 close to the light guide bar 151 and the front wall of the receiving groove 124. The light emitted by the light source 152 is transmitted to the gap between the light guide bar 151 and the front wall of the receiving groove 124, and then transmitted from the gap between the light-transmitting portion 153 and the front wall of the receiving groove 124 to the inclined surface of the light-transmitting portion 153. The light passes through the light-transmitting portion 153 and finally irradiates the front side surface of the aluminum alloy decorative strip 130.

[0079] The light source 152 has a plurality of lamp beads arranged at intervals. The above-mentioned light transmission method first irradiates the light of the lamp beads to the interval between the light guide bar 151 and the front wall of the receiving groove 124, and then guides the light at the interval between the light guide bar 151 and the front wall of the receiving groove 124 out through the light-transmitting portion 153. The light guide bar 151 directly transmits the light of the lamp beads to the light-transmitting portion 153 and the decorative strip 130, avoiding the uneven light emitted by the lamp beads arranged at intervals to form alternating bright and dark areas on the decorative strip 130, thereby improving the visual effect.

[0080] Furthermore, the light-transmitting portion 153 protrudes forward from the aluminum alloy trim 130. The front side of the aluminum alloy trim 130 is configured as an inclined surface, and the side of the front side of the aluminum alloy trim 130 away from the light-emitting device 150 is located in front of the light-transmitting portion 153. By adopting this technical solution, the light emitted by the light-emitting device 150 is ensured to be completely illuminated by the front side of the aluminum alloy trim 130, and not to be emitted to other areas, thereby improving light utilization. In addition, the inclined surface of the aluminum alloy trim 130 can adjust the angle of light reflection, allowing users to better observe the position of the aluminum alloy trim 130 and better remind users of the position of the door body 10.

[0081] And if the door body 10 is applied to a refrigeration device with two door bodies 10, the light emitted by the light-emitting device 150 of one door body 10 will not shine on the decorative strips of the adjacent door body 10, avoiding the problem of light being reflected by the decorative strips of the adjacent door body 10 and causing poor visual experience for users.

[0082] In one embodiment of the present invention, the light emitting device 150 is installed on the front side of the embedded structure 131 .

[0083] Specifically, the embedded structure 131 has a groove 1312 with an open front. The light-emitting device 150 matches and is embedded in the groove 1312. The structure from the groove wall of the groove 1312 on the side away from the aluminum alloy trim 130 to the outer wall of the embedded structure 131 on the side away from the aluminum alloy trim 130 forms a snap-fit portion 1311. To prevent the light-emitting device 150 from obstructing the engagement of the snap-fit portion 1311 with the snap-fit portion 125, the snap-fit portion 1311 protrudes from the light-emitting device 150 in the front-to-back direction. The portion of the snap-fit portion 1311 protruding from the light-emitting device 150 is used to engage with the snap-fit portion 125.

[0084] The lighting device 150 is connected to the wall of the groove 1312 via a snap-fit structure. Specifically, the snap-fit structure includes a limit buckle 154 extending rearward from the rear side of the light-transmitting portion 153 and a retaining protrusion 1313 protruding longitudinally from the inner wall of the groove 1312. The limit buckle 154 retains the rear side of the retaining protrusion 1313 to limit the lighting device 150 in the front-to-back direction.

[0085] To facilitate the engagement of the retaining buckle 154 with the retaining protrusion 1313, a gap is provided longitudinally between the retaining buckle 154 and the light guide bar 151. The retaining buckle 154 includes an elastic portion 1541 and a retaining portion 1542 extending from the end of the elastic portion 1541 away from the light-transmitting portion 153 toward the retaining protrusion 1313. The gap between the retaining buckle 154 and the light guide bar 151 provides space for the elastic portion 1541 to deform.

[0086] The assembly process of the light-emitting device 150 and the embedded structure 131 is as follows: the light-emitting device 150 is moved backward so that it fits into the groove 1312 of the embedded structure 131. During the movement of the light-emitting device 150, the retaining portion 1542 is lifted by the retaining protrusion 1313, and the elastic portion 1541 is deformed until the retaining portion 1542 passes over the retaining protrusion 1313, so that the front side of the retaining portion 1542 of the limiting buckle 154 mates with the rear side of the retaining protrusion 1313, completing the assembly of the light-emitting device 150 and the embedded structure 131.

[0087] In one embodiment of the present invention, the groove 1312 extends to both ends of the embedded structure 131 in the length direction to form openings. The openings at both ends of the groove 1312 facilitate the passage of the wiring harness of the light source 152 device.

[0088] like Figure 7 As shown, in order to prevent the light emitting device 150 from sliding off the openings at both ends of the groove 1312, the door body 10 further includes fixing members 160 installed on both sides of the length direction of the embedded structure 131. The fixing members 160 limit the light emitting device 150 in the length direction by abutting against both ends of the length direction of the light emitting device 150.

[0089] like Figure 11 and Figure 12 As shown, the fixing member 160 has a threading hole 161 that exposes both ends of the light emitting device 150 in the length direction. The wire harness of the light source 152 device passes through the openings at both ends of the groove 1312 and then comes out from the threading hole 161 of the fixing member 160.

[0090] The fixing piece 160 is connected to the rear side of the embedded structure 131 and the side facing away from the aluminum alloy trim 130 in the longitudinal direction by a snap. In order to guide the fixing piece 160 when installing the fixing piece 160 and improve the reliability of the connection between the fixing piece 160 and the embedded structure 131, the fixing piece 160 has a sleeve portion 162 that is sleeved on both ends of the embedded structure 131 in the longitudinal direction.

[0091] The fixing member 160 also includes a support portion 163 that abuts the side of the aluminum alloy trim 130 that is longitudinally closer to the light-emitting device 150. The aluminum alloy trim 130 supports the support portion 163, thereby enhancing the stability of the fixing member 160. The fixing member 160 also includes a stopper 164 that abuts the front side of the light-emitting device 150 to limit its forward movement. This stopper 164 further prevents the light-emitting device 150 from escaping the groove 1312 of the embedded structure 131.

[0092] like Figure 13 As shown, the present invention further provides a refrigeration device, comprising a cabinet 20 and the aforementioned door 10. The door 10 is mounted on the cabinet 20 to open or close the cabinet 20.

[0093] The refrigeration equipment described in the present invention is equipment for refrigerating or freezing items, such as a refrigerator, a wine cabinet or a beverage cabinet.

[0094] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
