[0029] See also Figure 1 to Figure 2 , an assembly structure of a freezer blister door body, comprising a door body 1, and a fixing assembly 2, wherein the door body 1 comprises a shell 101 and a sealing member 103, the fixing assembly 2 comprises an upper frame bar 201, a side frame bar 203 and a first fixing member 202, the fixing assembly 2 is arranged in the shell 101, the sealing member 103 is fixedly connected to the fixing assembly 2, the upper frame bar 201 and the side frame bar 203 are connected by the first fixing member 202, and the fixing assembly 2 is fixedly connected to the side frame bar 203 by the first fixing member 202. Figure 3 The upper end of the shell 101, the outer wall of the first fixing member 202 and the outer wall of the upper frame bar 201 are all arc-shaped convex surfaces, the top of the arc-shaped convex surface is tangent to the vertical direction, and the bottom of the arc-shaped convex surface is tangent to the horizontal direction. The arc-shaped convex surfaces of the first fixing member 202 and the upper frame bar 201 respectively leave gaps with the arc-shaped convex surfaces of the shell 101, and the outer walls of the upper edges of the first fixing member 202 and the upper frame bar 201 are respectively interference fit with the inner walls of the shell 101.

[0030] The present application adopts a design in which the top end of the arc-shaped convex surface is tangent to the vertical direction and the bottom end of the arc-shaped convex surface is tangent to the horizontal direction. Therefore, even if the shell 101 is too small to fit the fixing component 2 due to insufficient precision of the blister process, the shell 101 can be fastened to the fixing component 2 by using the outer wall of the first fixing member 202 and the upper frame bar 201 respectively having an interference fit with the inner wall of the shell 101. At the same time, a design in which gaps are left between the arc-shaped convex surface of the first fixing member 202 and the upper frame bar 201 and the arc-shaped convex surface of the shell 101, respectively, leaves a margin for the curvature of the arc-shaped convex surface of the shell 101, thereby preventing the curvature of the arc-shaped convex surface of the shell 101 from being too small due to insufficient precision of the blister process and affecting the installation of the freezer door, thereby reducing the precision requirements of the blister process.

[0031] like Figures 4 to 5 As shown, the first fixing member 202 includes an L-shaped portion 2022 and an arc-shaped portion 2021, the fixing assembly 2 also includes a lower frame bar 205 and a second fixing member 204, the outer sides of the L-shaped portion 2022 are respectively provided with a first mounting member 2121 and a second mounting member 2221, the first mounting member 2121 includes a first bending portion 2122 and a second bending portion 2123, the overlapping portion of the first bending portion 2122 and the second bending portion 2123 forms a first right-angle support plate 2124, the upper frame bar 201 is provided with a second right-angle support plate 2011, the two sides of the second right-angle support plate 2011 are respectively perpendicular to the horizontal direction and the vertical direction, after assembly, the first right-angle support plate 2124 and the second right-angle support plate 2011 are fitted together;

[0032] See also Figure 6 The second mounting member 2221 is provided with a partition 2222, and a support plate 2031 is provided in the side frame bar 203, and the support plate 2031 is perpendicular to the vertical direction. After assembly, the partition 2222 is fitted with the support plate 2031, and the support plate 2031 and the second right-angle support plate 2011 are respectively conducive to improving the structural stability of the side frame bar 203 and the upper frame bar 201, and preventing the side frame bar 203 and the upper frame bar 201 from being deformed when impacted. During installation, the first right-angle support plate 2124 and the second right-angle support plate 2011 are fitted together, which increases the adaptability of the first fixing member 202 and the upper frame bar 201, and the partition 2222 and the support plate 2031 are fitted together, which increases the adaptability of the first fixing member 202 and the side frame bar 203. Finally, refer to Figure 1 The second fixing member 204 is arranged on the lower side of the outer shell 101, and the lower frame bar 205 and the side frame bar 203 are connected through the second fixing member 204. The outer walls of the outer edges of the side frame bar 203 and the second fixing member 204 are respectively interference fit with the inner wall of the outer shell 101.

[0033] The working principles of the side frame strips and the second fixing member are similar to those of the upper frame strips and the first fixing member, and their specific working principles will not be elaborated in this application.

[0034] Optionally, the first fixing member 202, the side frame bar 203 and the second fixing member 204 are respectively set to two, the two first fixing members 202 are respectively set at the two ends of the upper side of the inner wall of the outer shell 101, the two side frame bars 203 are respectively set on both sides of the inner wall of the outer shell 101, and the two second fixing members 204 are respectively set at the two ends of the lower side of the inner wall of the outer shell 101, and the first fixing member 202 and the second fixing member 204 are connected through the side frame bar 203.

[0035] like Figure 1 and Figure 3 As shown, the door body 1 also includes a sealing member 103, which is arranged in a rectangular shape. The outer wall of the sealing member 103 is provided with a triangular convex surface, and the top of the triangular convex surface is provided with two fixing plates 1032 inclined toward the outer wall of the sealing member 103, and the two fixing plates 1032 are inclined upward and downward respectively. The second mounting member 2221 is provided with a groove 2223 on one side close to the sealing member 103, and the openings at both ends of the groove 2223 are provided with protrusions, and the top of the protrusion is provided with protrusions from close to the groove to close to the sealing member. The seal has two gradually descending and gradually rising inclined surfaces 2231. After assembly, the two sides of the triangular convex surface are respectively fitted with the two raised inclined surfaces 2231, and the two fixing plates 1032 are respectively snapped on the two sides of the two protrusions facing the groove 2223. The seal 103 can not only prevent the items in the freezer from being contaminated by the outside and keep the freezer clean and hygienic, but also the fixing plate 1032 can be made to cooperate with the inclined surface 2231 by pressing the seal 103, which facilitates the installation of the seal 103.

[0036] like Figure 1 As shown, the door body 1 includes a screen assembly 105, the side and top of the screen assembly 105 are fixedly connected to the side frame bar 203 and the top frame bar 201 respectively, and the screen assembly is used to display the temperature and operating status of the screen.

[0037] Among them, it needs to be further explained that the door body 1 includes a first inner glass 106 and a second inner glass 107, and the side and bottom edges of the first inner glass 106 and the second inner glass 107 are respectively fixedly connected to the side frame bar 203 and the bottom frame bar 205, and the upper edges of the first inner glass 106 and the second inner glass 107 are fixedly connected to the lower edge of the screen assembly 105, and a cavity is provided between the first inner glass 106 and the second inner glass 107. By adopting the design of double-layer inner glass, it can effectively isolate the external air and keep the temperature inside the refrigerator stable.

[0038] It should be further explained that the door body 1 includes an outer glass 104, and the outer glass 104 is arranged between the screen assembly 105 and the outer shell 101. The outer glass 104 can not only improve the overall aesthetics of the refrigerator, but also prevent the screen assembly 105 from being damaged.

[0039] Among them, it needs to be further explained that the door body includes a limit plate 102, and the limit plate 102 is fixedly installed at the bottom of the shell 101. When the freezer is opened, the limit plate 102 will be driven to rotate. If the opening angle of the freezer is too large, the limit plate 102 will be stuck by the cabinet body to prevent the freezer door from being opened excessively, thereby improving the sealing performance of the freezer and extending the service life of the freezer.

[0040] It should be further explained that the housing 101 is formed by vacuum forming, and the upper frame strip 201 is formed by extrusion forming. Vacuum forming and extrusion forming processes are more cost-effective than traditional injection molding processes.

[0041] It should be further explained that the first fixing member 202 is injection molded, and the injection molding process can ensure the precision requirements of the first mounting component 2121 and the second mounting component 2222 on the first fixing member 202 .
