TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a door handle assembly, a door assembly and a refrigeration equipment. BACKGROUND

[0002] At present, in the related art, aluminum alloy is usually selected as the handle of the door body of the refrigerator. However, compared with steel plate, the aluminum alloy has a large thermal expansion coefficient and a small elastic modulus. Under the same load bearing or temperature change condition of the door body, the handle of the door body made of aluminum alloy is more likely to deform, which leads to warping deformation of the handle of the door body and problems such as poor adhesion of the door seal, cold leakage and condensation. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve the technical problem in the related art that the handle of the door body made of aluminum alloy is prone to deformation, which leads to warping deformation of the handle of the door body and problems such as poor adhesion of the door seal, cold leakage and condensation.

[0004] To this end, the present application provides a door handle assembly in the first aspect.

[0005] The second aspect of the present application provides a door assembly.

[0006] The third aspect of the present application provides a refrigeration equipment.

[0007] Therefore, the present application provides a door handle assembly, which comprises a stand column, a support member and a handle.

[0008] The door handle assembly provided by the present application includes a column, a support member and a handle. Among them, the column is in the shape of an elongated strip, that is, the column is in the shape of an elongated strip as a whole, and the column includes a column body, the column body extends along the length direction of the column, and a bending flange is provided on one side of the column body, and a bending groove is formed between the bending flange and the column body. The support member is provided on the column, and one end of the support member is connected to the bending flange, and the other end of the support member is connected to the column body. A cavity structure is enclosed between the support member, the column body and the bending flange. That is, one end of the support member is placed on the bending flange and connected to the bending flange, and the other end of the support member is placed on the column body and connected to the column body. In this way, the support member, the column body and the bending flange can enclose a cavity structure. The cavity structure can be used to improve the deformation resistance of the door handle assembly, reduce the warping deformation of the door handle assembly, and avoid the door seal from not sticking, cold leakage and condensation.

[0009] The handle is provided on the column, and one end of the handle is connected to the column body, while the other end of the handle extends in a direction away from the column body. A gripping groove is formed between the handle and the column to facilitate gripping by the user. The gripping groove and the cavity structure are respectively located on opposite sides of the column body, that is, the gripping groove is provided at one end of the column body plate surface, and the cavity structure is provided at the other end of the column body plate surface, and the gripping groove and the cavity structure are respectively located on opposite sides of the column body plate surface. Since the gripping groove and the cavity structure are respectively located on opposite sides of the column body, structural balance and stability can be achieved, further enhancing the anti-deformation capability of the door handle assembly and reducing warping deformation of the door handle assembly.

[0010] By providing a bent flange on one side of the column body and connecting the bent flange and the column body through a support member, a cavity structure is formed on the column. Due to the provision of the cavity structure, when the door handle assembly is subjected to external force, the frame composed of the column body, the bent flange and the support member can disperse the stress, avoid stress concentration in a certain area, and reduce the risk of deformation of the door handle assembly due to stress concentration. As a connecting component, the support member not only connects and fixes the column body and the bent flange together, but also provides additional support for the door handle assembly. This support can effectively resist deformation when the door handle assembly is squeezed, and at the same time can increase the rigidity of the door handle assembly and improve its anti-deformation ability. In addition, by providing one end of the handle connected to the column body and the other end extending in a direction away from the column body, a gripping groove is formed between the handle and the column for the user to hold. Moreover, the gripping groove and the cavity structure are respectively arranged on two opposite sides of the column body. Since the gripping groove and the cavity structure are respectively located on two opposite sides of the column body, structural balance and stability can be achieved, thereby further enhancing the deformation resistance of the door handle assembly and reducing the warping deformation of the door handle assembly.

[0011] According to the door handle assembly of the technical solution of the present application, the following additional technical features can be provided.

[0012] In some technical solutions, a bending groove is formed between the bending flange and the column body, one end of the support member is connected to the bending flange, and the other end of the support member is connected to the column body, so as to cover the bending groove by the support member to form a cavity structure.

[0013] In this technical solution, the bending groove formed between the bending flange and the column body facilitates the installation of the support member and helps to form a stable and strong cavity structure. One end of the support member is connected to the bending flange, and the other end is connected to the column body. This connection not only enhances the overall structural strength of the column, but also forms a deformation-resistant cavity structure by covering the bending groove with the support member.

[0014] In some technical solutions, a cross-section perpendicular to the length direction of the column is taken, and in the cross-section, the cross-sectional shape of the cavity structure is trapezoidal or rectangular.

[0015] In this technical solution, by setting the cross-sectional shape of the cavity structure to be trapezoidal or rectangular in the cross-section perpendicular to the length direction of the column, the mechanical properties of the cavity structure are optimized, and the overall performance of the door handle assembly is improved.

[0016] In some technical solutions, the support member is a support plate, and the support plate is provided with openings, the openings are in communication with the cavity of the cavity structure, and the number of openings is multiple, and the multiple openings are uniformly distributed along the length direction of the support plate.

[0017] In this technical solution, the support member is set as a support plate, and openings are provided on the support plate, which are in communication with the cavity of the cavity structure. This allows the foamed thermal insulation material to enter the cavity structure through the openings, ensuring that the foamed thermal insulation material can fully fill the cavity structure, thereby improving the thermal insulation performance and overall performance of the door assembly. The number of openings is multiple, and the multiple openings are uniformly distributed along the length direction of the support plate, which ensures that the foamed thermal insulation material can fully enter the cavity structure through the openings, and ensures that the foamed thermal insulation material can fully fill the cavity structure.

[0018] In some technical solutions, the column further includes a boss, the boss is arranged on one side of the column body close to the cavity structure, and extends along the length direction of the column body.

[0019] In the technical solution, the column further comprises a boss. The boss is arranged on one side of the column body close to the cavity structure and extends along the length direction of the column body. The purpose of arranging the boss is mainly to increase the rigidity and strength of the column. The boss here plays the role of a reinforcing rib. By increasing the boss, the anti-deformation ability of the column when subjected to external force can be effectively improved, thereby ensuring the overall stability and durability of the door handle assembly.

[0020] In some technical solutions, optionally, a cross section is taken along the length direction perpendicular to the column, and in the cross section, the boss protrudes in the thickness direction of the column body, and the cross-sectional shape of the boss is trapezoidal or rectangular.

[0021] In the technical solution, the design of the boss enhances the rigidity and strength of the column. The boss protrudes in the thickness direction of the column body, forming a reinforcing rib structure. This design enables the column to better disperse stress when subjected to external force, thereby improving the anti-deformation ability.

[0022] In some technical solutions, optionally, the door handle assembly further comprises a mounting member arranged on the column body for mounting and fixing the door handle assembly.

[0023] In the technical solution, the door handle assembly further comprises a mounting member. The mounting member is arranged on the column body for mounting and fixing the door handle assembly. Through the mounting member, the door handle assembly can be firmly fixed to the door body of the refrigerator and other refrigeration equipment, ensuring its stability and durability during use.

[0024] In some technical solutions, optionally, the mounting member comprises a connecting portion and a fixing portion connected to each other, the connecting portion is connected to the column body, and the fixing portion extends away from the holding groove. In a cross section perpendicular to the length direction of the column, the cross-sectional shape of the mounting member is Y-shaped.

[0025] In the technical solution, the mounting member comprises a connecting portion and a fixing portion connected to each other. The connecting portion is connected to the column body, and the fixing portion extends away from the holding groove. This facilitates the installation of the door handle assembly to the door assembly. The Y-shaped cross section of the mounting member not only provides strong structural support but also improves the convenience of installation and fixation. The Y-shaped cross section forms a natural transition between the connecting portion and the fixing portion. This design not only enhances the rigidity and strength of the mounting member but also improves its stability when subjected to force.

[0048] An embodiment of the present application provides a door handle assembly 100, comprising: a column 110, the column 110 being in an elongated strip shape, the column 110 including a column body 112, the column body 112 extending along the length direction of the column 110, and a bent flange 114 being provided on one side of the column body 112; a support member 120, the support member 120 being provided on the column 110, and one end of the support member 120 being connected to the bent flange 114, and the other end of the support member 120 being connected to the column body 112; 2 connection, the support member 120, the column body 112 and the bent flange 114 enclose a cavity structure 130; a handle 140 is provided on the column 110, and one end of the handle 140 is connected to the column body 112, and the other end of the handle 140 extends in a direction away from the column body 112, and a gripping groove 150 is formed between the handle 140 and the column 110; wherein the gripping groove 150 and the cavity structure 130 are respectively located on opposite sides of the column body 112.

[0049] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, the door handle assembly 100 includes a column 110, a support member 120 and a handle 140. The column 110 is in a long strip shape, that is, the column 110 is in a long strip shape as a whole, and the column 110 includes a column body 112, and the column body 112 extends along the length direction of the column 110, as shown in FIG. Figure 1As shown, the length direction of the column 110 is L, that is, the column body 112 extends along the length direction L of the column 110. One side of the column body 112 is provided with a bent flange 114, and a bent groove 116 is formed between the bent flange 114 and the column body 112. The support 120 is arranged on the column 110, and one end of the support 120 is connected with the bent flange 114, and the other end of the support 120 is connected with the column body 112, and a cavity structure 130 is enclosed among the support 120, the column body 112 and the bent flange 114. That is, one end of the support 120 is arranged on the bent flange 114 and connected with the bent flange 114, and the other end of the support 120 is arranged on the column body 112 and connected with the column body 112, so that the support 120, the column body 112 and the bent flange 114 can enclose a cavity structure 130, which can improve the anti-deformation ability of the door handle assembly 100, reduce the warping deformation of the door handle assembly 100, and avoid the problems of poor sealing, leakage and condensation.

[0050] Specifically, as shown, Figure 2 The handle 140 is arranged on the column 110, and one end of the handle 140 is connected with the column body 112, and the other end of the handle 140 extends away from the column body 112, and a holding groove 150 is formed between the handle 140 and the column 110 to facilitate the user to hold. The holding groove 150 and the cavity structure 130 are respectively located on opposite sides of the column body 112, that is, the holding groove 150 is arranged at one end of the plate surface of the column body 112, the cavity structure 130 is arranged at the other end of the plate surface of the column body 112, and the holding groove 150 and the cavity structure 130 are respectively located on the two sides of the plate surface of the column body 112 which are away from each other. Since the holding groove 150 and the cavity structure 130 are respectively located on opposite sides of the column body 112, the structure is balanced and stable, and the anti-deformation ability of the door handle assembly 100 is further improved, and the warping deformation of the door handle assembly 100 is reduced.

[0051] By arranging the bent flange 114 on one side of the column body 112 and connecting the bent flange 114 and the column body 112 through the support 120, a cavity structure 130 is formed on the column 110. Due to the arrangement of the cavity structure 130, when the door handle assembly 100 is subjected to external force, the frame composed of the column body 112, the bent flange 114 and the support 120 can disperse stress and avoid stress concentration in a certain area, thereby reducing the risk of deformation of the door handle assembly 100 due to stress concentration. The support 120 serves as a connecting component that not only connects and fixes the column body 112 and the bent flange 114 together, but also provides additional support for the door handle assembly 100. This support can effectively resist deformation when the door handle assembly 100 is subjected to pressure, and can also improve the rigidity and anti-deformation ability of the door handle assembly 100. In addition, by arranging the handle 140 with one end connected to the column body 112 and the other end extending away from the column body 112, a holding groove 150 is formed between the handle 140 and the column 110 to facilitate user holding. The holding groove 150 and the cavity structure 130 are arranged on opposite sides of the column body 112, respectively. Since the holding groove 150 and the cavity structure 130 are located on opposite sides of the column body 112, respectively, the structure is balanced and stable, which further enhances the anti-deformation ability of the door handle assembly 100 and reduces the warping deformation of the door handle assembly 100.

[0052] Specifically, at present, the surface of the aluminum alloy can be treated in various ways in the related art, such as anodic oxidation, electrophoretic coating, sandblasting, spraying, etc., which can enhance the surface hardness, wear resistance and aesthetics. In view of the aesthetic requirements, aluminum alloy is usually used as the door handle of the refrigerator. However, compared with steel plate, the aluminum alloy has a large thermal expansion coefficient and a small elastic modulus. Under the same door load or temperature change condition, the door handle of the aluminum alloy is more prone to deformation, which leads to warping deformation of the door handle and causes problems such as poor adhesion of the door seal, cold leakage and condensation.

[0053] To solve this problem, the present application provides a door handle assembly for a refrigerator, which comprises a column and a handle, wherein the column comprises a column body and a bent flange arranged on one side of the column body, and the handle is arranged on the other side of the column body. Figures 1 to 3As shown, by providing a bent flange 114 on one side of the column body 112 and connecting the bent flange 114 to the column body 112 using a support member 120, a cavity structure 130 is formed on the column 110. Cavity structure 130 can enhance the bending stiffness of the door handle assembly 100 by increasing the material thickness and the moment of inertia of the cross section. In mechanics, the moment of inertia of the cross section is an important indicator for measuring the bending resistance of a structure. By forming cavity structure 130, the moment of inertia of the cross section of the column 110 is significantly increased, thereby improving its ability to resist bending deformation. Furthermore, cavity structure 130 also has a certain degree of thermal stability. Due to the large thermal expansion coefficient of aluminum alloy, temperature changes can easily cause material deformation. The presence of cavity structure 130 can absorb and alleviate this thermal expansion effect to a certain extent, allowing the door handle assembly 100 to maintain a more stable shape and performance during temperature changes.

[0054] This not only optimizes the structure of the door handle assembly 100 but also significantly improves its deformation resistance. The presence of the cavity structure 130 allows the column 110 to effectively disperse stress when subjected to external forces through the framework formed by the column body 112, the bent flange 114, and the support member 120, thereby avoiding stress concentration and reducing the risk of deformation of the door handle assembly 100 due to stress concentration.

[0055] Specifically, if Figure 2 As shown, the support member 120 serves as a connecting component, connecting and securing the column body 112 and the bent flange 114 while also providing additional support for the door handle assembly 100. This support structure effectively resists deformation when the door handle assembly 100 is squeezed or subjected to temperature changes, maintaining the rigidity and stability of the door handle assembly 100. Furthermore, by providing a handle 140 with one end connected to the column body 112 and the other end extending away from the column body 112, a gripping groove 150 is formed between the handle 140 and the column 110. This not only facilitates the user's grip but also further enhances the structural stability of the door handle assembly 100.

[0056] Because the gripping groove 150 and the cavity structure 130 are located on opposite sides of the column body 112, this arrangement achieves structural balance and stability, further enhancing the deformation resistance of the door handle assembly 100. Even in harsh operating environments, such as large temperature fluctuations or when the door is under heavy load, the door handle assembly 100 can maintain its good shape and performance, avoiding problems such as non-stick door seals, cold air leakage, and condensation caused by deformation. This effectively solves the problem of aluminum alloy door handles on side-by-side refrigerators in the related art that are prone to deformation when the door is loaded or the temperature fluctuates.

[0057] In some embodiments, optionally, as Figure 1 andFigure 2 As shown, a bending groove 116 is formed between the bending flange 114 and the column body 112, one end of the support member 120 is connected with the bending flange 114, and the other end of the support member 120 is connected with the column body 112, so as to cover the bending groove 116 by the support member 120 to form a cavity structure 130.

[0058] Specifically, as shown in Figure 2 By setting the bending groove 116 between the bending flange 114 and the column body 112, the bending groove 116 between the bending flange 114 and the column body 112 provides convenience for the installation of the support member 120, and helps to form a stable and strong cavity structure 130. One end of the support member 120 is connected with the bending flange 114, and the other end is connected with the column body 112. This connection not only enhances the overall structural strength of the column 110, but also forms a deformation-resistant cavity structure 130 by covering the bending groove 116 with the support member 120.

[0059] Specifically, the design of the bending groove 116 enables the support member 120 to be more closely fitted with the column body 112 and the bending flange 114, thereby enhancing the overall rigidity and stability of the door handle assembly 100. As a connecting and supporting component, the support member 120 not only firmly connects the column body 112 and the bending flange 114 together, but also provides an additional support point for the door handle assembly 100. When the door handle assembly 100 is subjected to external force, the support member 120 can effectively disperse stress and avoid deformation caused by stress concentration.

[0060] In addition, the combined design of the bending groove 116 and the support member 120 also has certain thermal stability. Since the thermal expansion coefficient of aluminum alloy material is relatively large, temperature changes can easily cause material deformation. The combination of the bending groove 116 and the support member 120 can to some extent absorb and alleviate this thermal expansion effect, so that the door handle assembly 100 can maintain a more stable shape and performance when the temperature changes.

[0061] In some embodiments, as shown in Figure 2 As shown, in a cross section perpendicular to the length direction of the column 110, the cross-sectional shape of the cavity structure 130 is trapezoidal or rectangular.

[0062] Specifically, as shown in Figure 2 By setting the cross-sectional shape of the cavity structure 130 to be trapezoidal or rectangular in a cross section perpendicular to the length direction of the column 110, this design not only optimizes the mechanical properties of the cavity structure 130, but also improves the overall performance of the door handle assembly 100.

[0063] Specifically, in mechanics, the cross-sectional moment of inertia is an important indicator of the bending resistance of a structure. By forming a cavity structure 130 on the column 110, the cross-sectional moment of inertia of the column 110 is significantly increased, thereby improving the ability to resist bending deformation, and the trapezoidal or rectangular cross-sectional shape allows the cavity structure 130 to better disperse stress when subjected to external forces. Compared with circular or irregular shapes, trapezoidal or rectangular cross-sectional shapes have a larger cross-sectional moment of inertia, which means they can resist bending deformation more effectively. Therefore, when the door handle assembly 100 is subjected to external forces, such as impact forces when the user opens or closes the door or thermal stress caused by temperature changes inside the refrigerator, the trapezoidal or rectangular cavity structure 130 can better maintain its shape and stability.

[0064] In addition, the trapezoidal or rectangular cross-sectional shape also helps improve the manufacturing efficiency and cost-effectiveness of the door handle assembly 100. This regular geometric shape makes mold design and manufacturing simpler, thereby reducing production costs. At the same time, the regular cross-sectional shape also makes the assembly and debugging process of the door handle assembly 100 smoother, improving production efficiency.

[0065] In some embodiments, optionally, as shown in Figure 1 and Figure 2 The support 120 is a support plate 122, and the support plate 122 is provided with an opening 124 that is in communication with the cavity of the cavity structure 130, wherein the number of openings 124 is multiple, and the multiple openings 124 are uniformly distributed along the length direction of the support plate 122.

[0066] Specifically, as shown in Figure 1 and Figure 2 By setting the support 120 as a support plate 122 and providing the support plate 122 with openings 124 that are in communication with the cavity of the cavity structure 130, the foamed insulation material can enter the cavity structure 130 through the openings 124, ensuring that the foamed insulation material can fully fill the cavity structure 130, thereby improving the insulation performance and overall performance of the door assembly 200. The number of openings 124 is multiple, and the multiple openings 124 are uniformly distributed along the length direction of the support plate 122, which can ensure that the foamed insulation material can fully enter the cavity structure 130 through the openings 124, ensuring that the foamed insulation material can fully fill the cavity structure 130.

[0067] Specifically, the design of the openings 124 aims to close the cavity structure while ensuring that the foamed thermal insulation material can flow smoothly into the cavity structure 130, thereby avoiding affecting the thermal insulation performance of the door body and reducing the risk of condensation. The plurality of openings 124 on the support plate 122 not only provide a channel for the flow of foamed thermal insulation material, but also ensure the uniformity of filling inside the cavity structure 130 through its uniform distribution design. In the manufacturing process of the refrigerator and other refrigeration equipment 300, the door body assembly 200 usually needs to be foamed to improve its thermal insulation performance. If the support plate 122 is not provided with openings 124, the foamed thermal insulation material will not be able to flow into the cavity structure 130, resulting in a decrease in the thermal insulation performance of the door body assembly 200 and an increase in the risk of condensation. By providing a plurality of uniformly distributed openings 124, it can be ensured that the foamed thermal insulation material can fully fill the cavity structure 130, thereby improving the thermal insulation performance and overall performance of the door body assembly 200.

[0068] In addition, the shape of the openings 124 can be set as a rectangle, a square, or a circle, etc. The rectangular or square opening 124 structure has rounded corners, which can effectively reduce stress concentration and improve the strength of the support plate 122. When subjected to external force, the rounded corner design can make the stress more evenly distributed on the support plate 122, avoiding material deformation or damage caused by stress concentration.

[0069] In some embodiments, optionally, as shown in Figure 1 and Figure 2 The post 110 further includes a boss 118, which is arranged on one side of the post body 112 close to the cavity structure 130 and extends along the length direction of the post body 112.

[0070] Specifically, as shown in Figure 1 and Figure 2 The post 110 further includes a boss 118. The boss 118 is arranged on one side of the post body 112 close to the cavity structure 130 and extends along the length direction of the post body 112. The purpose of arranging the boss 118 is mainly to increase the rigidity and strength of the post 110, and the boss 118 here plays the role of a reinforcing rib. By increasing the boss 118, the anti-deformation ability of the post 110 when subjected to external force can be effectively improved, thereby ensuring the overall stability and durability of the door handle assembly 100.

[0071] Specifically, the design of the boss 118 strengthens the column body 112 structurally. Since the boss 118 extends along the length direction of the column body 112 and forms an integral whole with the column body 112, the cross-sectional moment of inertia and torsional stiffness of the column 110 are increased. When subjected to external forces, such as impact forces when a user opens or closes the door or thermal stress caused by temperature changes inside the refrigerator, the boss 118 can effectively disperse stress and avoid deformation problems caused by stress concentration.

[0072] In addition, the design of the boss 118 also helps to improve the manufacturing precision and assembly efficiency of the door handle assembly 100. During the manufacturing process, the boss 118 can serve as a positioning reference to help accurately control the relative positions between the components of the door handle assembly 100. During the assembly process, the boss 118 can serve as an assembly guide to enable the components to be more smoothly assembled together, improving assembly efficiency and product quality.

[0073] In some embodiments, optionally, as shown in Figure 2 the cross section perpendicular to the length direction of the column 110, the boss 118 protrudes in the thickness direction of the column body 112, and the cross-sectional shape of the boss 118 is trapezoidal or rectangular.

[0074] Specifically, as shown in Figure 2 the design of the boss 118 enhances the stiffness and strength of the column 110, and the boss 118 protrudes in the thickness direction of the column body 112, forming a structure of a reinforcing rib, as shown in Figure 2 the thickness direction of the column body 112 is D, that is, the boss 118 protrudes in the thickness direction D of the column body 112, and this design enables the column 110 to better disperse stress when subjected to external forces, thereby improving the deformation resistance.

[0075] Specifically, the cross-sectional shape of the boss 118 is trapezoidal or rectangular, and since the trapezoidal or rectangular cross-sectional shape has a large cross-sectional moment of inertia, it can more effectively resist bending deformation. When the column 110 is subjected to external forces, such as impact forces when a user opens or closes the door or thermal stress caused by temperature changes inside the refrigerator, the trapezoidal or rectangular boss 118 can better maintain its shape and stability.

[0076] Moreover, the trapezoidal or rectangular cross-sectional shape also helps to improve manufacturing efficiency and reduce costs. This regular geometric shape makes mold design and manufacturing simpler, thereby reducing production costs. In addition, the design of the boss 118 can also be adjusted according to specific application requirements. For example, when higher stiffness is required, the height or width of the boss 118 can be increased.

[0077] In some embodiments, optionally, as shown in Figure 1 andFigure 3 As shown, the door handle assembly 100 further comprises a mounting member 160 arranged on the column body 112 for mounting and fixing the door handle assembly 100.

[0078] Specifically, as shown in Figure 1 and Figure 3 , the door handle assembly 100 further comprises a mounting member 160. The mounting member 160 is arranged on the column body 112 for mounting and fixing the door handle assembly 100. Through the mounting member 160, the door handle assembly 100 can be firmly fixed on the door of the refrigerator or other refrigeration equipment 300, ensuring its stability and durability during use.

[0079] Specifically, the mounting member 160 is usually designed to match the shape and size of the column body 112 to ensure a tight fit between them. During installation, the mounting member 160 can be connected to the column body 112 in an integrated or welded manner, and then connected to the door assembly 200 through bolts, nuts or other fasteners, thereby achieving the fixation of the door handle assembly 100. In addition, the mounting member 160 can also be designed to have elastic or adjustable structure to adapt to the needs of different door thickness and installation accuracy.

[0080] In some embodiments, optionally, as shown in Figure 2 and Figure 3 , the mounting member 160 comprises a connecting portion 162 and a fixing portion 164, the connecting portion 162 is connected to the column body 112, and the fixing portion 164 extends away from the holding groove 150. In the cross section perpendicular to the length direction of the column 110, the cross-sectional shape of the mounting member 160 is Y-shaped.

[0081] Specifically, as shown in Figure 3 , the mounting member 160 comprises a connecting portion 162 and a fixing portion 164. The connecting portion 162 is connected to the column body 112, and the fixing portion 164 extends away from the holding groove 150. This facilitates the installation of the door handle assembly 100 on the door assembly 200. The Y-shaped cross section of the mounting member 160 not only provides strong structural support, but also improves the convenience of installation and fixation. The Y-shaped cross section makes the mounting member 160 form a natural transition between the connecting portion 162 and the fixing portion 164. This design not only enhances the rigidity and strength of the mounting member 160, but also improves its stability when under stress.

[0082] Specifically, the connecting portion 162 of the mounting piece 160 is designed to match the shape and size of the connecting portion 162 of the column body 112, to ensure a close fit therebetween. The fixing portion 164 extends away from the holding groove 150, to be connected to the door body of the refrigerator or other refrigeration equipment 300. The Y-shaped cross-section forms a triangular support structure between the connecting portion 162 and the fixing portion 164 of the mounting piece 160, which can effectively disperse stress and avoid deformation or damage caused by stress concentration when the door handle assembly 100 is subjected to external force, such as impact force when the user opens or closes the door.

[0083] In some embodiments, as shown in Figure 1 , the door handle assembly 100 is an aluminum alloy integrally formed structure.

[0084] Specifically, as shown in Figure 1 , by providing the door handle assembly 100 as an aluminum alloy integrally formed structure, the required cross-sectional shape can be obtained, ensuring the integrally formed and precise geometry of the door handle assembly 100. The door handle assembly 100 with an aluminum alloy integrally formed structure and an extrusion molding process has excellent mechanical properties, precise geometry, and good surface quality, while improving manufacturing efficiency and reducing production costs.
