In some embodiments, as shown in connection with fig. 1-10, a door body structure 100 is provided, comprising: a door shell 110, a foaming layer 120 and an absorbing deformation 130. The foaming layer 120 is filled in the door case 110. The absorbing deformation 130 is disposed on the foaming layer 120. The absorbing deformation 130 includes a housing 132 and a plurality of separating ribs 142, the housing 132 includes a cavity 152, the plurality of separating ribs 142 are disposed in the cavity 152, and the plurality of separating ribs 142 divide the cavity 152 into a plurality of spaces 154.

The door body structure 100 provided by the present disclosure includes a door shell 110, a foaming layer 120, and an absorbing deformation 130. Foaming is performed in the door case 110 to form the foaming layer 120. The deformation amount of the foaming layer 120 is absorbed by disposing the absorbing deformation member 130 in the foaming layer 120, so as to reduce the deformation amount of the door body. Specifically, the absorptive deformation 130 includes a housing 132 and a plurality of dividing ribs 142. The plurality of dividing ribs 142 are disposed in the cavity 152 of the housing 132 and divide the cavity 152 into a plurality of independent small spaces 154.

The door body structure 100 of the present disclosure is provided with the absorbing deformation member 130 in the foaming layer 120, and the absorbing deformation member 130 is internally provided with the partition rib 142 and the plurality of independent small spaces 154 formed by the partition rib 142. Under the condition of external pressure, the separation ribs 142 and the independent small spaces 154 can deform, so that the deformation of the foaming layer 120 is absorbed, the overall deformation of the door body is reduced, and the strength of the door body is improved. In addition, the plurality of independent small spaces 154 can reduce heat convection of air, and meanwhile, the heat conductivity coefficient of the air is lower than that of the foaming layer, so that the heat preservation effect of the refrigeration equipment 200 can be improved.

Compared with the prior art in which the reinforcing iron is installed in the foaming layer 120, the door body provided by the present disclosure does not increase the weight of the door body by arranging the absorbing deformation member 130 in the foaming layer 120, and further does not need to redesign the matching members such as the door seal and the hinge, and further does not increase the design cost.

Compared with the scheme that the reinforcing ribs are arranged on the door lining in the related art, the door body provided by the present disclosure is capable of absorbing the deformation of the foaming layer 120 through volume change by arranging the absorbing deformation piece 130 in the foaming layer 120, thereby achieving the effect of reducing the deformation of the door body, being not influenced by the temperature difference between the inside and the outside, and improving the application adaptability of the door body.

Optionally, the plurality of separation ribs 142 includes a plurality of first ribs and a plurality of second ribs. The plurality of first ribs are disposed in the cavity 152 at an inclination with respect to a sidewall of the cavity 152. The plurality of second ribs are disposed in the cavity 152 at an inclination with respect to a sidewall of the cavity 152. Wherein the first plurality of ribs and the second plurality of ribs are disposed crosswise to divide the cavity 152 into a plurality of spaces 154.

In this embodiment, the plurality of first ribs and the plurality of second ribs are disposed in the cavity 152 in a crossing manner to divide the plurality of cavities 152 into a plurality of spaces 154. In addition, the plurality of first ribs and the plurality of second ribs are disposed in the cavity 152 in an inclined manner, and when the housing 132 receives pressure, the inclined first ribs and second ribs are more likely to deform, thereby promoting the absorption of the deformation amount of the foam layer 120. The divided spaces 154 are combined, so that the absorption of the deformation amount of the foam layer 120 can be improved.

Alternatively, as shown in conjunction with fig. 5 and 9, the partition rib 142 includes: a first connector 144 and a second connector 146. One end of the first connecting body 144 is connected to one side wall of the housing. One end of the second connecting body 146 is connected to the other end of the first connecting body 144, and the other end of the second connecting body 146 is connected to the other side wall of the housing. Wherein an included angle α is formed between the first connector 144 and the second connector 146.

In this embodiment, the spacer 142 includes a first connector 144 and a second connector 146 that are connected. One end of the first connector 144 and the second connector 146, which are far away from each other, are respectively connected with the inner side walls of the cavities 152 on both sides. And, an included angle is formed between the first connector 144 and the second connector 146. In this way, when the casing 132 is pressed, the first connector 144 and the second connector 146 are pressed, so that deformation is easy to occur, and further the deformation of the foaming layer 120 can be absorbed, and the deformation of the whole size of the foaming layer 120 is reduced, so that the problems of weight increase and thermal insulation performance reduction of the foaming layer 120 can not be caused on the premise of solving the deformation of the foaming door body and the box body.

Optionally, the first connector 144 and the second connector 146 are of a unitary structure.

In this embodiment, the separation rib 142 of the integral structure increases strength and improves stability during use.

Optionally, the value range α of the included angle is: alpha is less than 180 DEG and 15 deg.

In this embodiment, the deformation range of the absorbing deformation member 130 can be further increased by reasonably setting the value of the included angle, so as to increase the absorption of the deformation amount of the foaming layer 120. Specifically, the included angle includes: 45 °, 60 °, 90 °, 120 ° or 135 °.

Alternatively, as shown in connection with fig. 7 to 9, the housing 132 includes a first plate body 133 and a second plate body 134 disposed opposite to each other, and a first end plate 135 and a second end plate 136 disposed opposite to each other, and a first connection plate 137 and a second connection plate 138 disposed opposite to each other. The first and second end plates 135 and 136 are located at both sides of the first and second plate bodies 133 and 134, respectively. The first connection plate 137 and the second connection plate 138 are located at the other two sides of the first plate 133 and the second plate 134, respectively. The first and second plates 133, 134, the first and second end plates 135, 136, and the first and second connection plates 137, 138 are connected to define a cavity 152.

Wherein the first connection plate 137 and the second connection plate 138 are disposed toward the long side of the door body for contact with one side or both sides of the door case 110. The first end plate 135 and the second end plate 136 face the outer surface of the door body and the inner surface of the door body, respectively. The first end plate 135 includes a plurality of grooves for fitting with a door liner on the inner surface of the door body. The first plate 133 and the second plate 134 are disposed toward the wide sides of the door body, respectively.

Alternatively, both ends of the separation rib 142 are connected to the first plate body 133 and the second plate body 134, respectively. The first plate 133 and the second plate 134 face the wide sides of the door, respectively. That is, the first plate 133 and the second plate 134 are disposed at intervals along the length direction of the door. In this way, when the first plate 133 and the second plate 134 are subjected to pressure, the partition rib 142 deforms along the length direction of the door, and the partition rib 142 generates a compressive deformation amount along the length direction of the door, so that the absorption of the deformation amount of the foam layer 120 can be improved, the deformation amount of the overall size of the foam layer 120 can be reduced, and the door strength can be improved.

Alternatively, as shown in connection with fig. 5 and 9, the opening of the included angle α is directed towards the first end plate 135 or towards the second end plate 136.

In this embodiment, the absorptive deformation 130 is positioned in the door shell 110 in combination to direct the opening of the included angle α toward the first end plate 135 or toward the second end plate 136. In this way, the contact area between the first plate 133 and the second plate 134 of the absorbing deformation member 130 and the foam layer 120 is maximized, and thus the compression force is maximized, and the separation rib 142 is inclined with respect to the first plate 133 and the second plate 134 by opening the included angle toward the first end plate 135 or the second end plate 136. In this way, when the absorbing deformation member 130 receives an external force, the partition rib 142 can be deformed more easily, and further, the absorbing of the deformation amount of the foaming layer 120 can be improved, and the overall deformation amount of the door body can be reduced.

Alternatively, as shown in connection with fig. 5 and 9, a plurality of separation ribs 142 are spaced apart within the cavity 152 in the direction from the first end plate 135 to the second end plate 136.

In this embodiment, in combination with the arrangement of the absorbing deformation 130 in the door shell 110, the plurality of separating ribs 142 are spaced apart in the thickness direction of the door body in the cavity 152 to separate the cavity 152 into a plurality of independent small spaces 154 in the thickness direction of the door body. Along the thickness direction of the door body, the plurality of independent small spaces 154 can play a role in absorbing deformation. And, a plurality of independent little spaces 154 can reduce the heat convection, can prevent the heat conduction in the door body thickness direction, and then promote the heat preservation effect of the door body.

Alternatively, as shown in conjunction with fig. 5 and 9, the cross-sectional shape of the spacer 142 includes a V-shape.

In this embodiment, the cavity 152 is partitioned into a plurality of separate small spaces 154 by using V-shaped partition ribs 142. The V-shaped spacer 142 is more easily deformed when subjected to an external force, so that the absorption of the deformation of the foaming layer 120 can be improved, and the overall deformation of the door body can be reduced.

Alternatively, the cross-sectional shape of the separation rib 142 includes a W shape.

In this embodiment, the cavity 152 is partitioned into a plurality of separate small spaces 154 by using the W-shaped partition rib 142. The W-shaped spacer 142 is more easily deformed when subjected to an external force, and thus can improve the absorption of the deformation of the foaming layer 120 and reduce the overall deformation of the door body.

Alternatively, the cross-sectional shape of the separation rib 142 includes an X-shape.

In this embodiment, the interior of the cavity 152 is partitioned into a plurality of separate small spaces 154 by the use of the X-shaped partition ribs 142. The X-shaped spacer 142 is more easily deformed when subjected to an external force, and thus can improve the absorption of the deformation of the foaming layer 120 and reduce the overall deformation of the door body.

In some embodiments, as shown in connection with fig. 1, 2, 3 and 6, the number of absorptive deformations 130 is multiple. The plurality of absorbing deformation members 130 are spaced apart in the foaming layer 120 along the length direction of the door body.

In this embodiment, a plurality of absorbing deformation members 130 are disposed along the length direction of the door body, and the absorbing deformation members 130 are spaced apart in the foaming layer 120. In this way, the deformation amount of the foaming layer 120 can be uniformly absorbed by the plurality of absorbing deformation members 130, and thus the stability of the overall structure of the door body can be improved.

Compared with the related art, the door body deformation prevention scheme by providing the reinforcing iron has the advantage that the deformation amount of the door body is smaller only for the area near the reinforcing iron, so that the deformation amount of the rest part is still larger. The door body that this disclosure provided through set up a plurality of absorption deformation piece 130 along the length direction interval of the door body, separates a plurality of regions with the door body, and every region all is provided with absorption deformation piece 130, and every region can reduce the deflection under the effect of absorption deformation piece 130, and then reduces the holistic deflection of the door body to promote the holistic stability of the door body.

Optionally, the number of the plurality of absorbing deformation members 130 is proportional to the length of the door body, that is, in the case that the length of the door body is larger, the number of the absorbing deformation members 130 can be increased to reduce the deformation of the door body, so as to effectively improve the strength of the door body.

In some embodiments, as shown in connection with fig. 1, 2, 3 and 6, the number of absorptive deformations 130 is multiple. The length of the absorbing deformation 130 is less than 2/3 of the width of the door body in the width direction of the door body. The plurality of absorbing deformation members 130 are alternately distributed in the foaming layer 120 along the length direction of the door body.

In this embodiment, the extension direction of the absorbing deformation 130 in the width direction of the door body is the length direction, the length of the absorbing deformation 130 is L, and the width of the door body is W, l.ltoreq.2/3×w. In this way, the deformation of the door body can be absorbed through the absorbing deformation piece 130, and meanwhile, the situation that the absorbing deformation piece 130 is too long and the strength of the door body is affected is avoided.

Further, as shown in fig. 1, 2, 3 and 6, two adjacent absorbing deformation members 130 are staggered along the length direction of the door body, so as to improve the strength of the door body. Meanwhile, by arranging the plurality of absorbing deformation members 130 distributed in a staggered manner, the contact area between the absorbing deformation members 130 and the foaming layer 120 can be increased, and the absorbing effect on the deformation amount of the foaming layer 120 can be improved. Moreover, the strength of the foaming layer 120 can be improved through staggered arrangement through two adjacent staggered distribution, and the overall strength of the door body can be improved.

Alternatively, as shown in fig. 1, 2, 3 and 6, the plurality of absorbing deformation members 130 are arranged in two rows in the width direction of the door body. The plurality of absorbing deformation members 130 of the first row are spaced apart along the length direction of the door body. The plurality of absorbing deformation members 130 of the second row are spaced apart along the length direction of the door body. Along the length direction of the door body, the absorbing deformation pieces 130 of the first row and the absorbing deformation pieces 130 of the second row are distributed in a staggered manner. In this way, on the one hand, by providing a plurality of absorptive deformation members 130 in a row, the contact area between the absorptive deformation members 130 and the foam layer 120 can be increased, and the deformation amount can be reduced. Meanwhile, the plurality of absorbing deformation pieces 130 are distributed in two rows in a staggered manner, so that the plurality of absorbing deformation pieces 130 are uniformly distributed, and the absorbing deformation balance is improved. Moreover, by the staggered distribution, the overlong absorbing deformation pieces 130 can be avoided, and the overall strength of the door body is further improved.

Alternatively, as shown in connection with fig. 1, 2, 3 and 6, a plurality of absorptive deformation members 130 positioned in a first row have one end in contact with the door shell 110 of the first long side 112 of the door body and the other end extending toward the second long side 114 of the door body. One end of the plurality of absorbing deformation members 130 located in the second row contacts the door shell 110 of the second long side 114 of the door body, and the other end extends toward the first long side 112. Between two adjacent absorbing deformation members 130 in the same row, one absorbing deformation member 130 is provided in the corresponding other row. Like this, through the crisscross setting of the absorption deformation piece 130 of two lines, and the absorption deformation piece 130 extends along the width direction of the door body, and then can follow the length direction and the width direction of the door body and realize the absorption to the deflection, and promote absorptive equilibrium, reduce the whole deflection of the door body, and then promote the bulk strength of the door body.

Optionally, the plurality of absorbing deformation members 130 of the first and second rows are projected along the length direction of the door body, and the projection of the absorbing deformation member 130 of the first row is overlapped with the projection of the absorbing deformation member 130 of the second row. In this way, the contact area between the absorbing deformation member 130 and the foaming layer 120 can be increased, so as to increase the absorbing deformation, further reduce the deformation of the local area of the foaming layer 120, and increase the strength of the door body.

Alternatively, the length of the absorptive deformation 130 in the first row is equal to the length of the absorptive deformation 130 in the second row. Thus, the device is convenient to install and improves the production efficiency.

Alternatively, the length of the absorptive deformation 130 in the first row is not equal to the length of the absorptive deformation 130 in the second row. Specifically, the absorbing deformation members 130 with different lengths can be arranged in different areas of the door body according to the structural characteristics of the door body so as to meet the structural characteristics of the area and the service field Jing Xuqiu, thereby improving the strength of the door body and prolonging the service life of the door body.

Alternatively, the lengths of the plurality of absorptive deformations 130 located in the same row are the same. Thus, in the installation process, the installation process can be simplified, and the installation efficiency is improved.

Alternatively, the lengths of the plurality of absorptive deformations 130 located in the same row are not the same. Like this, can set up the length of the absorption deformation piece 130 of corresponding region according to the structural feature and the frequency of use of the door body of door body same side region, and then can promote the intensity and the increase of service life of door body.

Optionally, the plurality of absorbing deformation members 130 are uniformly distributed along the length direction of the door body, so as to promote the uniform absorption of the deformation amount of the foaming layer 120.

Optionally, the door body is divided into three regions, and along the length direction of the door body, the three regions are a first side region, a middle region and a second side region in sequence. The distribution density of the absorbing deformation 130 is different in the three areas, and the distribution density of the absorbing deformation 130 is proportional to the deformation. The larger the deformation amount of the foaming layer 120, the larger the distribution density of the absorbing deformation 130. It should be noted that the distribution density is not infinite, and the size of the distribution density is relatively three areas to promote the uniformity of the absorption and the strength of the door body.

Alternatively, the distribution density of the absorbing deformation 130 in the middle region is greater than the distribution density of the absorbing deformation 130 in the first side region and the second side region, respectively. Considering that the middle area of the door body corresponds to the inside of the box body, the temperature inside the box body is lower than that of the two sides, so that the corresponding temperature difference between the inside and the outside is larger, and the box body is easy to deform. Therefore, since the plurality of absorptive deformation members 130 provided in the middle region have a higher density than the two sides, the absorptive deformation amount can be increased, the overall deformation amount of the door body can be reduced, and the door body strength can be improved.

It should be noted that the distribution form of the plurality of absorbing deformation members 130 is not limited to two rows, and may be specifically set according to the size of the door body, which is not described herein.

Alternatively, the length L of the absorbing deformation 130 satisfies: l is more than or equal to 1/3 XW and less than or equal to 2/3 XW. The length L of the absorbing deformation member 130 is reasonably set, so that the balance of deformation absorption of the foaming layer 120 can be improved, and the strength of the door body is improved.

Specifically, the specific value of the length L of the absorbing deformation 130 includes 1/3 XW, 1/2 XW, or 2/3 XW.

In some embodiments, the number of the absorbing deformation members 130 is plural, and the absorbing deformation members 130 are distributed in the foaming layer 120 at intervals along the length direction of the door body. The length of the absorbing deformation 130 is greater than or equal to 2/3 of the width of the door body and less than or equal to the width of the door body in the width direction of the door body. The door body further comprises a reinforcing iron arranged on the foaming layer 120 and one or more sides of the foaming layer 120.

In this embodiment, the extending direction of the absorbing deformation 130 along the width direction of the door body is the length direction, the length of the absorbing deformation 130 is L, and the width of the door body is W, and then the length of the absorbing deformation 130 and the width W of the door body satisfy: w is more than 2/3×W and less than or equal to L. Further, reinforcing iron is provided on one or more sides of the foaming layer 120. By setting the length of the absorbing deformation 130 to be greater than 2/3×w and less than or equal to W, the contact area of the absorbing deformation 130 and the foaming layer 120 is increased, thereby increasing the area of absorbing deformation and reducing the deformation amount of the foaming layer 120. Meanwhile, considering that the length of the absorbing deformation 130 provided in the foaming layer 120 is equal to or close to the width of the door body, it has an effect on the strength of the door body, and further, the strength of the door body is improved by providing reinforcing iron at one or more sides of the foaming layer 120. Thus, by adopting the door body provided by the disclosure, the deformation of the door body is reduced, and the strength of the door body is improved.

Meanwhile, the anti-condensation effect can be achieved.

Optionally, the insulating layer comprises a layer of PVC (Polyvinyl chloride polyvinylchloride).

In this embodiment, by providing a PVC layer between the foaming layer 120 and the absorbing deformation 130, soft contact between the foaming layer 120 and the absorbing deformation 130 is achieved, and gas can be prevented from flowing between the absorbing deformation 130 and the foaming layer 120, and thus heat transfer can be reduced, and thus the temperature difference between the inside and the outside of the door body can be reduced, to reduce the deformation amount. Meanwhile, the anti-condensation effect can be achieved.

Optionally, the insulating layer comprises a sealant layer.

In this embodiment, by filling the sealant layer between the foaming layer 120 and the absorbing deformation 130, the flow of gas between the absorbing deformation 130 and the foaming layer 120 can be prevented, and thus the heat transfer can be reduced, and thus the temperature difference between the inside and the outside of the door body can be reduced, to reduce the deformation amount. Meanwhile, the anti-condensation effect can be achieved.

Optionally, the spaces 154 of the absorbing deformation member 130 are filled with a heat-conducting medium, and the heat-conducting medium is a heat-conducting medium with a low heat conductivity coefficient, so as to reduce heat convection of air, reduce temperature difference between the inside and outside of the door body, and reduce deformation. Meanwhile, the condensation risk can be reduced by reducing the temperature difference between the inside and the outside of the door body.

Optionally, the heat conducting medium comprises: hollow glass microspheres.

The hollow glass microspheres have smaller particle size and certain fluidity, and the hollow glass microspheres have lower heat conduction efficiency due to the specificity of the hollow structure in the hollow glass microspheres, and the air flow in the absorbing deformation piece 130 cannot flow to form convection due to the small gap between the hollow glass microspheres, so that a good heat insulation effect can be achieved.

The door provided by the present disclosure reduces the heat conduction system by adopting the absorbing deformation 130 filled with hollow glass microspheres, and reduces the heat convection inside the absorbing deformation 130. Further, since the hollow glass microspheres have fluidity, under the condition that the absorbing deformation member 130 receives external pressure, the hollow glass microspheres can be rapidly filled to absorb the change of the size of the space 154 caused by the deformation of the deformation member 130, thereby improving the absorption of the deformation of the foaming layer 120, further reducing the overall deformation of the door body, and improving the heat preservation effect of the foaming layer 120.
