Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0039] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.
[0040] The inventors discovered through research that in the manufacturing of refrigeration equipment, the doors and cabinets of refrigeration equipment are typically connected by hinges, with the door rotating around the hinge when opened. For large-capacity refrigeration equipment with a volume of 500 liters or more, the length and width of the corresponding doors and cabinets are also relatively large, resulting in significant torque at the connection between the door and the hinge when opening. In this case, a hinge reinforcement plate is usually installed on the inner side of the door to enhance the connection between the hinge and the door. However, the reliability of the current hinge reinforcement plate 1 is insufficient. Specifically, the current hinge reinforcement plate typically adopts a "U"-shaped structure, connecting to the inner door foam layer via flanges on both sides. Due to material cost constraints, the length of the flanges is no more than 20 millimeters, resulting in a small contact area with the door foam layer and affecting the connection strength. Therefore, after repeated opening and closing of the door, the hinge reinforcement plate 1 may separate from the door foam layer, leading to problems such as door dents or flange cracks, affecting the quality of the refrigeration equipment.
[0041] In order to solve the aforementioned technical problems, the inventors have innovatively designed the following technical solutions, and the specific implementation scheme of this application will be described in detail below with reference to the accompanying drawings.
[0042] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a hinge reinforcement plate 1 provided in this embodiment. Figure 2 This is a front view of a hinge reinforcement plate 1 provided in this embodiment. The hinge reinforcement plate 1 includes a hinge body, which includes a first hinge body 100, a second hinge body 110, a third hinge body 120, a fourth hinge body 130, and a fifth hinge body 140 connected to each other. One end of the first hinge body 100 is connected to the second hinge body 110, and the other end is connected to the third hinge body 120. The second hinge body 110 and the third hinge body 120 extend in the same direction, and the second hinge body 110 and the third hinge body 120 extend in the same direction on the first hinge body 100.
[0043] The end of the third hinge body 120 away from the first hinge body 100 is connected to the fourth hinge body 130. The fourth hinge body 130 extends in the same direction as the first hinge body 100. The end of the fourth hinge body 130 away from the third hinge body 120 is connected to the fifth hinge body 140. The fifth hinge body 140 extends in the same direction as the third hinge body 120. The fifth hinge body 140 extends on the fourth hinge body 130 in a direction away from the third hinge body 120.
[0044] In this embodiment, the second hinge body 110 is used to fix the inner side of the first door sidewall 200. The second hinge body 110 and the third hinge body 120 extend in the same direction relative to the first hinge body 100, realizing the first flange of the hinge reinforcement plate 1. The first hinge body 100, the third hinge body 120, and the fourth hinge body 130 form a "step-like" shape. The fifth hinge body 140 extends on the fourth hinge body 130 in a direction away from the third hinge body 120. That is, the fifth hinge body 140 and the third hinge body 120 extend in opposite directions on the fourth hinge body 130, realizing the second flange of the hinge reinforcement plate 1. Thus, by flanging twice consecutively, the contact area between the hinge reinforcement plate 1 and the door foam layer 201 inside the refrigeration equipment 2 is effectively increased, improving the reliability of the connection between the hinge reinforcement plate 1 and the door foam layer 201.
[0045] The first hinge body 100 includes a first material passage hole 101 penetrating through the first hinge body 100, and the fourth hinge body 130 includes a second material passage hole 131 penetrating through the fourth hinge body 130. In this embodiment, during the manufacturing process of the refrigeration device 2, after the hinge reinforcing plate 1 is fixed to the inner side of the first door sidewall 200, foaming material is injected into the door body of the refrigeration device 2. The foaming material can flow through the first material passage hole 101 and the second material passage hole 131 to the side of the first hinge body 100 away from the second hinge body 110 and the side of the fourth hinge body 130 away from the first hinge body 100. That is, the foaming material can flow through the first material passage hole 101 and the second material passage hole 131 to the portion between the hinge reinforcing plate 1 and the second door sidewall 202 of the door body, and after the foaming material solidifies, it forms the door body foam layer 201. At this point, the door foam layer 201 completely wraps around the hinge reinforcement plate 1, significantly enhancing the reliability of the connection between the hinge reinforcement plate 1 and the door foam layer 201.
[0046] Further, please see Figure 2 In this embodiment, the extension direction of the first hinge body 100 is the first direction A1, and the extension direction of the fourth hinge body 130 is also the first direction A1. The extension direction of the second hinge body 110, the third hinge body 120, and the fifth hinge body 140 is also the second direction A2. The first direction A1 and the second direction A2 are perpendicular to each other. During the manufacturing process of the refrigeration device 2, the extension direction of the first door sidewall 200 is the second direction A2, and the extension direction of the second hinge body 110 is also set to the second direction A2. In this way, it can be ensured that the second hinge body 110 is completely fitted with the inner side of the first door sidewall 200, which facilitates the connection between the hinge reinforcing plate 1 and the first door sidewall 200.
[0047] In this embodiment, since the first direction A1 and the second direction A2 are perpendicular to each other, this design divides the hinge reinforcement plate 1 into 5 mutually perpendicular hinge bodies, so that the entire hinge reinforcement plate 1 forms a regular and stable three-dimensional structure, which is beneficial to improving its mechanical properties, ensuring that it can withstand the corresponding force in all directions, and enhancing its structural strength when connected with the door foam layer 201, reducing problems such as deformation caused by external impact or long-term use.
[0048] Furthermore, please see again Figure 2 In the second direction A2, the second hinge body 110 has a first dimension H1, the third hinge body 120 has a second dimension H2, and the fifth hinge body 140 has a third dimension H3. The first dimension H1 is greater than the second dimension H2, the first dimension H1 is greater than the third dimension H3, and the first dimension H1 is greater than or equal to the sum of the first dimension H1 and the second dimension H2. In this embodiment, during the manufacturing process of the refrigeration device 2, since the second hinge body 110 of the hinge reinforcing plate 1 is directly fixed to the inner side of the first door side wall 200, and the first door side wall 200 is opened and closed with the box body through the hinge 210, it is necessary to ensure that the hinge reinforcing plate 1 has greater strength near the opening and closing area to prevent shaking during opening and closing. Thus, by making the first dimension H1 of the second hinge body 110 larger than the second dimension H2 and the third dimension H3, and larger than the sum of the second dimension H2 and the third dimension H3, on the one hand, the contact area between the second hinge body 110 and the door foam layer 201 is maximized, achieving an effective and firm connection with the door foam layer 201; on the other hand, it prevents the sum of the dimensions of the third hinge body 120 and the fifth hinge body 140 from exceeding the maximum width of the first door sidewall 200.
[0049] In this embodiment, the size of the second dimension H2 ranges from 12 mm to 20 mm. For example, the size of the second dimension H2 can be 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm, etc. The size of the third dimension H3 ranges from 12 mm to 20 mm. For example, the size of the third dimension H3 can be 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm, etc.
[0050] It is worth noting that the specific sizes of the second size H2 and the third size H3 are not specifically limited here, and can be selected from the above size range according to actual needs.
[0051] Furthermore, please see again Figure 2In the first direction A1, the size of the first hinge body 100 is the fourth dimension H4, and the size of the fourth hinge body 130 is the fifth dimension H5, where the fifth dimension H5 is larger than the fourth dimension H4. In this embodiment, by making the size of the fourth hinge body 130 larger than the size of the first hinge body 100, during the manufacturing process of the refrigeration device 2, the thickness of the door foam layer 201 on the side of the fourth hinge body 130 away from the second hinge body 110 is greater than the thickness of the door foam layer 201 on the side of the first hinge body 100 away from the second hinge body 110. This design can further improve the tightness and reliability of the connection between the hinge reinforcing plate 1 and the foam layer.
[0052] In this embodiment, the size of the fourth dimension H4 ranges from 30 mm to 40 mm. For example, the size of the fourth dimension H4 can be 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, or 40 mm. The size of the fifth dimension H5 ranges from 35 mm to 40 mm. For example, the size of the fifth dimension H5 can be 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, or 40 mm.
[0053] It is worth noting that the specific sizes of the fourth size H4 and the fifth size H5 are not specifically limited here, and can be selected from the above size range according to actual needs.
[0054] On direction A1, please refer again. Figure 2 The distance between the second hinge body 110 and the third hinge body 120 is a sixth dimension H6, which ranges from 65 mm to 75 mm. For example, the sixth dimension H6 can be 65 mm, 66 mm, 67 mm, 68 mm, 69 mm, 70 mm, 71 mm, 72 mm, 73 mm, 74 mm, and 75 mm. In this embodiment, the distance between the second hinge body 110 and the third hinge body 120 is limited to the sixth dimension H6, ensuring a stable connection of the hinge reinforcement plate 1 at the first door sidewall 200 while not exceeding the maximum width of the second door sidewall 202.
[0055] It is worth noting that the specific size of the sixth dimension H6 is not specifically limited here, and can be selected from the above size range according to actual needs.
[0056] Further, please see Figure 1, the second hinge body 110 includes fixing through holes 111 penetrating the second hinge body 110. The number of the fixing through holes 111 is multiple, and the multiple fixing through holes 111 are evenly arranged on the second hinge body 110. In this embodiment, the hinge reinforcing plate 1 is fixed to the side wall 200 of the first door body through the fixing through holes 111. When the number of the fixing through holes 111 is 4, the arrangement of the 4 fixing through holes 111 on the second hinge body 110 is as shown in Figure 1 shown.
[0057] In the embodiment, the diameter of the fixing through holes 111 is 5 mm to 10 mm. Exemplarily, the diameter of the fixing through holes 111 is 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.
[0058] It should be noted that the diameter of the fixing through holes 111 is not specifically limited herein and can be selected from the above size range according to actual needs.
[0059] Furthermore, please refer to Figure 1 and Figure 3 See Figure 3 which is a top view of a hinge reinforcing plate 1 provided in this embodiment. The shape of the fixing through holes 111 includes a circle, and the shapes of the first material passing through holes 101 and the second material passing through holes 131 include oblong shapes. In this embodiment, during the manufacturing process of the refrigeration device 2, the oblong material passing through holes can improve the flow filling rate of the foaming material.
[0060] It should be noted that the shapes of the fixing through holes 111 and the material passing through holes include but are not limited to the above shapes and can be selected according to actual situations.
[0061] Furthermore, please refer to Figure 3 see that the extending directions of the first material passing through holes 101 and the second material passing through holes 131 are the same, and the extending direction of the first material passing through holes 101 is the same as the extending direction of the first hinge body 100. The number of the first material passing through holes 101 is multiple, and the multiple first material passing through holes 101 are arranged on the first hinge body 100 at equal intervals.
[0062] In this embodiment, when there are 2 first material passing through holes 101, the 2 first material passing through holes 101 are arranged on the first hinge body 100 at equal intervals. At this time, the first material passing through holes 101 and the second material passing through holes 131 form a "pin" shape. During the manufacturing process of the refrigeration device 2, it can facilitate the foaming material to flow to and fill the part between the hinge reinforcing plate 1 and the second side wall 202 of the door body, and realize the stable connection between the hinge reinforcing plate 1 and the foaming layer 201 of the door body.
[0063] Furthermore, the first hinge body 100, the second hinge body 110, the third hinge body 120, the fourth hinge body 130, and the fifth hinge body 140 are integrally formed. In this embodiment, the hinge reinforcing plate 1 can be a single unit, and the connecting edge of two adjacent hinge bodies can be arc-shaped.
[0064] Based on the same inventive concept, this application also provides a refrigeration device 2, please refer to... Figure 4 , Figure 4 This is a schematic diagram of a refrigeration device 2 provided in this embodiment. The refrigeration device 2 includes a door, a housing (not shown in the figure), a hinge 210, and the aforementioned hinge reinforcement plate 1. The door includes a first door sidewall 200 and a door foam layer 201 located inside the door body. The hinge reinforcement plate 1 is embedded in the door foam layer 201, and the first hinge body 100 of the hinge reinforcement plate 1 is fixed to the inner side of the first door sidewall 200. The housing includes a housing sidewall (not shown in the figure). One end of the hinge 210 is connected to the housing sidewall, and the other end is connected to the hinge reinforcement plate 1 through the first door sidewall 200. The door can move relative to the housing through the hinge 210.
[0065] In this embodiment, the hinge reinforcement plate 1 is embedded in the door body foam layer 201. On one hand, during the manufacturing process of the refrigeration equipment 2, when foaming material is injected into the door body of the refrigeration equipment 2, the foaming material can flow through the first material passage hole 101 and the second material passage hole 131 to the portion between the hinge reinforcement plate 1 and the second door body sidewall 202. After the foaming material solidifies, it forms the door body foam layer 201. Thus, the door body foam layer 201 of the refrigeration equipment 2 can completely enclose the hinge reinforcement plate 1, significantly enhancing the reliability of the connection between the hinge reinforcement plate 1 and the door body foam layer 201.
[0066] On the other hand, the hinge reinforcement plate 1, through its design of two consecutive flanges (i.e., the third hinge body 120 and the fifth hinge body 140), effectively increases the contact area between the hinge reinforcement plate 1 and the foam layer inside the door of the refrigeration equipment 2, further enhancing the reliability of the connection between the hinge reinforcement plate 1 and the door foam layer 201. Therefore, the connection between the hinge reinforcement plate 1 and the door foam layer 201 in this embodiment is reliable, reducing the likelihood of separation between the hinge reinforcement plate 1 and the door foam layer 201 when the door of the refrigeration equipment 2 is opened and closed multiple times via the hinge 210. This reduces problems such as door dents or flange bursts, improving the quality of the refrigeration equipment 2.
[0067] Furthermore, in the extending direction of the second hinge body 110 of the hinge reinforcement plate 1, the size of the first door sidewall 200 is larger than the size of the second hinge body 110. The door also includes a second door sidewall 202, and a portion of the door foam layer 201 is located between the first hinge body 100 and the second door sidewall 202 of the hinge reinforcement plate 1, and between the fourth hinge body 130 of the hinge reinforcement plate 1 and the second door sidewall 202, wherein the first door sidewall 200 and the second door sidewall 202 are perpendicular to each other. In this embodiment, there is a gap between the second hinge body 110 and the second door sidewall 202 to ensure that a portion of the door foam layer 201 can fill the space between the first hinge body 100 and the second door sidewall 202, and to ensure that the door foam layer 201 can completely cover the hinge reinforcement plate 1.
[0068] It is worth noting that in this embodiment, the door body includes a first door body side wall 200 and a second door body side wall 202 that are arranged opposite to each other. The first door body side wall 200 and the second door body side wall 202 are connected and perpendicular to each other. The width of the first door body side wall 200 is much smaller than the width of the second door body side wall 202. The first door body side wall 200 is usually used to connect with the box body.
[0069] The refrigeration device 2 also includes a fixing component. The hinge 210 has a first through hole on the side near the first door side wall 200. The first door side wall 200 has a second through hole that penetrates the first door side wall 200 and corresponds to the first through hole. The second through hole is also corresponding to the fixing through hole 111 of the hinge reinforcing plate 1. The hinge 210 is connected to the door and the hinge reinforcing plate 1 through the cooperation of the fixing component with the first through hole, the second through hole and the fixing through hole 111.
[0070] It is worth noting that the fasteners can be bolts or screws. The specific type of fastener is not limited here and can be selected according to the actual situation.
[0071] In summary, this application provides a hinge reinforcement plate and a refrigeration device. The hinge reinforcement plate includes a hinge body, which comprises a first hinge body, a second hinge body, a third hinge body, a fourth hinge body, and a fifth hinge body. One end of the first hinge body is connected to the second hinge body, and the other end is connected to the third hinge body. The second and third hinge bodies extend in the same direction and on the first hinge body. The end of the third hinge body away from the first hinge body is connected to the fourth hinge body, which extends in the same direction as the first hinge body. The end of the fourth hinge body away from the third hinge body is connected to the fifth hinge body, which extends in the same direction as the third hinge body and on the fourth hinge body in a direction away from the third hinge body. The first hinge body includes a first through-hole penetrating the first hinge body, and the fourth hinge body includes a second through-hole penetrating the fourth hinge body. Thus, the aforementioned hinge reinforcement plate increases the contact area with the door foam layer inside the refrigeration equipment, effectively enhancing the connection between the hinge reinforcement plate and the door foam layer, thereby ensuring the reliability of the connection between the hinge reinforcement plate and the door foam layer.
[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
