Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, and particularly relates to a hinge mechanism and a refrigeration equipment. Background Art
[0002] Refrigeration equipment such as refrigerators needs to connect the box body and the door body through hinges to realize the opening and closing actions of the door body.
[0003] In the related art, for some refrigerator hinges with complex structures and high appearance requirements, the sheet metal stamping process cannot be used, and usually the die casting process is adopted for production.
[0004] However, inside the die-cast hinge, especially at the corners, defects such as air holes and inclusions are likely to occur. This defect reduces the mechanical properties of the hinge, especially the impact strength, resulting in the die-cast hinge being prone to deformation and fracture during transportation and use. Therefore, the die-cast hinge has technical defects such as poor mechanical strength and high failure rate. Summary of the Utility Model
[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.
[0006] Therefore, a first aspect of the utility model provides a hinge mechanism.
[0007] A second aspect of the utility model provides a refrigeration equipment.
[0008] In view of this, a first aspect of the utility model provides a hinge mechanism, which includes: a body, the body includes a base, a support portion and a hinge shaft, the support portion is arranged on the base, and the hinge shaft is arranged on the support portion; an embedded member, embedded in the body, and the embedded member is at least located in the intersection area of the base and the support portion.
[0009] In this technical solution, a hinge mechanism is defined, which can be applied to refrigeration equipment such as refrigerators and freezers. The box body and the door body in the refrigeration equipment are hinged together through the hinge mechanism, and the user can open or close the box body by rotating the door body.
[0010] The hinge mechanism includes a body, and the body forms the outer surface of the hinge. Specifically, the body includes a base, a support portion and a hinge shaft. There are screw holes on the base, and the base is connected to the door body or the box body on the refrigeration equipment through screws. The support portion is arranged on the base, and the hinge shaft is arranged on the support portion. The support portion can provide positioning and support for the hinge shaft, and the support portion can form a rotating swing arm between the base and the hinge shaft.
[0011] Among them, the base and the support part on the body are integrally formed by die-casting process. During the cooling process of the die-cast base and support part, thermal stress is likely to be generated, making it difficult to control the dimensional accuracy of the base and support part. In particular, the perpendicularity of the base and support part cannot be guaranteed. Moreover, defects such as pores and inclusions are likely to appear in the die-cast base and support part, and this defect is likely to cause the intersection area of the base and support part to be unable to bear the rated torque, increasing the probability of bending or even breaking at the intersection area of the base and support part.
[0012] In response to this, the present application pre-buries an embedded component inside the base and the support part. Specifically, the embedded component is first placed in the mold, and the embedded component is at least placed in the intersection area of the base and the support part. According to requirements, the embedded component can also extend to other areas. Then, casting material is injected into the mold to integrally form the base and the support part on the outside of the embedded component, so that the embedded component can be smoothly embedded into the intersection area of the body and the support part.
[0013] By pre-burying the embedded component in the body and the support part, the fluidity of the metal casting material can be effectively improved during the die-casting process, reducing the probability of defects such as pores and inclusions in the base and the support part, thereby effectively enhancing the mechanical strength of the base and the support part. Moreover, the embedded component pre-buried in the intersection area of the base and the support part can replace the body and the support part to resist part of the torque, thereby enhancing the structural strength of the base and the support part.
[0014] It can be seen that on the one hand, the embedded component can ensure the perpendicularity and dimensional accuracy between the base and the support part, reducing the subsequent compensation processing cost. On the other hand, the embedded component can also reduce the probability of problems such as bending or even breaking of the support part during use through strength reinforcement, so as to improve the mechanical strength of the hinge mechanism and reduce the failure rate. On the other hand, the embedded component can also improve the bearing capacity of the hinge mechanism, enabling the hinge mechanism to be applicable to heavy door bodies and broadening the application range of the hinge mechanism. Thus, the technical problems existing in the foregoing related technologies are solved, and further, the technical effects of improving the structural strength and dimensional accuracy of the hinge mechanism, reducing the failure rate of the hinge mechanism, and improving the yield rate of the hinge mechanism are achieved.
[0015] In addition, the above hinge mechanism provided by the present utility model may further have the following additional technical features:
[0016] In some technical solutions of the present utility model, optionally, the embedded component includes: a first insert, the first insert includes a first section and a second section, the first section is disposed inside the base, and the second section is connected to the first section, and a part of the second section is located inside the support part.
[0017] In this technical solution, the embedded component at least includes a first insert. The position where the first insert is located is divided into a first section and a second section. The first section is arranged inside the base, and the shape of the first section is adapted to the shape of the base to enhance the strength reinforcement effect of the first section on the base. The second section is arranged inside the support portion, and the first end of the second section is connected to the first section. Similarly, the shape of the second section is adapted to the shape of the support portion to enhance the strength reinforcement effect of the second section on the support portion.
[0018] Specifically, the connection portion between the first section and the second section corresponds to the intersection area of the base and the support portion. During the die-casting process, the metal casting material is effectively filled into the intersection area of the base and the support portion under the guiding action of the first section and the second section, so as to reduce the possibility of defects such as air holes and inclusions in the intersection area of the base and the support portion, and at the same time improve the perpendicularity of the base and the support portion. Moreover, the connected first section and second section can replace the base and the support portion inside the base and the support portion to resist part of the stress, thereby improving the structural strength of the base and the support portion.
[0019] In some technical solutions of the present utility model, optionally, the thickness of the first section is greater than or equal to 2 mm and less than or equal to 5 mm; the thickness of the second section is greater than or equal to 2 mm and less than or equal to 5 mm.
[0020] In this technical solution, the first section is in a plate shape, and the thickness of the first section needs to be greater than or equal to 2 mm and less than or equal to 5 mm. By limiting the thickness of the first section to be greater than or equal to 2 mm, it can be ensured that the first section can provide effective reinforcement for the base, thereby improving the load-bearing capacity of the base and reducing the probability of irreversible deformation of the base. By limiting the thickness of the first section to be less than or equal to 5 mm, the volume of the embedded component can be reduced on the basis of meeting the structural reinforcement requirements. On the one hand, the production cost is reduced, and on the other hand, it provides convenient conditions for the miniaturization design and lightweight design of the hinge mechanism.
[0021] The second section is in a plate shape, and the thickness of the second section needs to be greater than or equal to 2 mm and less than or equal to 5 mm. By limiting the thickness of the second section to be greater than or equal to 2 mm, it can be ensured that the second section can provide effective reinforcement for the support portion, thereby improving the load-bearing capacity of the support portion and reducing the probability of irreversible deformation of the support portion. By limiting the thickness of the second section to be less than or equal to 5 mm, the volume of the embedded component can be reduced on the basis of meeting the structural reinforcement requirements. On the one hand, the production cost is reduced, and on the other hand, it provides convenient conditions for the miniaturization design and lightweight design of the hinge mechanism.
[0022] In some technical solutions of the present utility model, optionally, the first insert is an L-shaped steel, or the first insert is a T-shaped steel.
[0023] In this technical solution, the first insert is obtained by cutting an L-shaped steel. Among the two perpendicular parts of the L-shaped steel, one part is embedded in the base, and the other part is embedded in the support part. The two perpendicular parts of the L-shaped steel have strong bending and torsion resistance capabilities, so as to replace the base and the support part to resist part of the bending and torsion moments, reduce the probability of irreversible deformation of the support part and the base, and thus achieve the technical effects of improving the structural strength of the hinge mechanism and reducing the failure rate of the hinge mechanism.
[0024] Similarly, the first insert can also be obtained by cutting a T-shaped steel. Among the two perpendicular parts of the T-shaped steel, one part is embedded in the base, and the other part is embedded in the support part. The two perpendicular parts of the T-shaped steel have strong bending and torsion resistance capabilities, so as to replace the base and the support part to resist part of the bending and torsion moments, reduce the probability of irreversible deformation of the support part and the base, and thus achieve the technical effects of improving the structural strength of the hinge mechanism and reducing the failure rate of the hinge mechanism. Among them, compared with the L-shaped steel, the T-shaped steel has a stronger structural reinforcement effect on the base, and the L-shaped steel or the T-shaped steel can be selected as the embedded component according to the weight requirement and the base strength requirement.
[0025] On the other hand, selecting the L-shaped steel and the T-shaped steel belongs to standard parts that can be directly purchased. Obtaining the first insert by cutting the L-shaped steel or the T-shaped steel can also eliminate the machining process of the first insert, thereby reducing the process complexity and production cost of the hinge mechanism.
[0026] In some technical solutions of the present utility model, optionally, the embedded component is of an integral structure; the base and the support part are of an integral structure, and the base and the support part jointly wrap the embedded component.
[0027] In this technical solution, the embedded component is of an integral structure, and the base and the support part on the body are integrally formed on the outside of the embedded component by die-casting process. Specifically, first place the embedded component in the mold, and the embedded component is at least placed in the intersection area of the base and the support part. According to requirements, the embedded component can also extend to other areas. Then inject the casting material into the mold to integrally form the base and the support part on the outside of the embedded component, so that the embedded component can be smoothly embedded into the intersection area of the body and the support part.
[0028] Preparing the base and the support part by die-casting forming process can reduce the process complexity of the hinge mechanism, is beneficial to improving the production efficiency of the hinge mechanism, and is beneficial to reducing the production cost of the hinge mechanism.
[0029] Moreover, by pre-embedding the embedded component in the body and the support part, the fluidity of the metal casting material can be effectively improved during the die-casting forming process, and the probability of pores and inclusion defects in the base and the support part can be reduced, thereby effectively enhancing the mechanical strength of the base and the support part. And the embedded component embedded in the intersection area of the base and the support part can replace the body and the support part to resist part of the moment, thereby enhancing the structural strength of the base and the support part.
[0030] In some technical solutions of the present utility model, optionally, the minimum distance between the embedded component and the outer surface of the body is in the range of: greater than or equal to 2 mm and less than or equal to 5 mm.
[0031] In this technical solution, the minimum distance between the embedded component and the outer surface of the main body is the spacing between the embedded component and the outer surface of the main body, and the spacing needs to be greater than or equal to 2 mm and less than or equal to 5 mm.
[0032] By limiting the distance between the embedded component and the outer surface of the main body to be greater than or equal to 2 mm and less than or equal to 5 mm, on the one hand, it is possible to avoid the cost and weight of the hinge mechanism being increased by an embedded component that is too large. On the other hand, it is possible to ensure the structural strength of the part of the main body outside the embedded component, and to avoid the part of the main body that is too thin being damaged by external forces.
[0033] In some technical solutions of the present utility model, optionally, the embedded component further includes: a second insert, and the second insert is embedded in the hinge shaft.
[0034] In this technical solution, the embedded component also includes a second insert, which is arranged in the hinge shaft, and the hinge shaft is sleeved on the outside of the second insert, or the hinge shaft is integrally formed with the support part and the base on the outside of the second insert. The dimensional accuracy of the hinge shaft directly affects the switching reliability of the door body. By pre-embedding the second insert inside the hinge shaft, the dimensional error of the hinge shaft can also be reduced, thereby improving the reliability and yield rate of the hinge mechanism. On the other hand, the second insert arranged inside the hinge shaft can share part of the bending torque for the hinge shaft, thereby improving the mechanical strength of the hinge mechanism and reducing the possibility of bending or even breaking of the hinge shaft.
[0035] In some technical solutions of the present invention, optionally, the second section is connected to the second insert.
[0036] In this technical solution, the first end of the second section is connected to the first section, and the second end of the second section is connected to the second insert. By connecting the first insert and the second insert together, an integrated internal skeleton can be formed inside the main body to reinforce the base, the support part and the hinge shaft, thereby enhancing the structural strength of the embedded component, allowing the embedded component to share more bending and torsional moments for the main body, thereby further enhancing the mechanical strength of the main body and reducing the probability of irreversible deformation of the main body.
[0037] In some technical solutions of the present utility model, optionally, the hardness of the embedded component is greater than the hardness of the base and the support portion.
[0038] In this technical solution, the hardness of the material of the embedded component is greater than the hardness of the material of the base and the hardness of the material of the support part. By arranging an embedded component with greater hardness inside the body, the embedded component can share more bending and torsional moments for the body, thereby further improving the mechanical strength of the hinge mechanism, reducing the probability of irreversible deformation of the hinge mechanism, further reducing the failure rate of the hinge mechanism, and broadening the applicable range of the hinge mechanism.
[0039] Specifically, the material of the embedded component is carbon steel, and the materials of the base and the support part include tin alloy and aluminum alloy.
[0040] The second aspect of the present utility model provides a refrigeration device, which includes: a hinge mechanism as described in any one of the above technical solutions; a box body, which is connected to one of the base and the hinge shaft; a door body, which is connected to the other of the base and the hinge shaft.

Therefore, this refrigeration device has the advantages of the hinge mechanism as described in any one of the above technical solutions, and can achieve the technical effects that the hinge mechanism as described in any one of the above technical solutions can achieve. To avoid repetition, it will not be elaborated here.
[0042] On this basis, the refrigeration device further includes a box body and a door body. The inside of the box body is used to store materials that need to be refrigerated. The box body includes an opening. The door body is hinged to the box body through the hinge mechanism. After assembly, the door body can rotate relative to the box body, so as to open and close the box body through the rotating door body.

[0053] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0054] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.
[0055] Next, refer to Figures 1 to 6 to describe a hinge mechanism and a refrigeration device according to some embodiments of the present invention.
[0056] As Figure 1 、 Figure 2 and Figure 4 shown, an embodiment of the present invention provides a hinge mechanism 100. The hinge mechanism 100 includes: a body 110, the body 110 includes a base 112, a support portion 114 and a hinge shaft 116, the support portion 114 is disposed on the base 112, and the hinge shaft 116 is disposed on the support portion 114; an embedded component 120, embedded in the body 110, and the embedded component 120 is at least located in the intersection area of the base 112 and the support portion 114.
[0057] In this technical solution, a hinge mechanism 100 is defined. The hinge mechanism 100 can be applied to refrigeration devices such as refrigerators and freezers. The box body and the door body in the refrigeration device are hinged together through the hinge mechanism 100, and the user can open or close the box body by rotating the door body.
[0058] The hinge mechanism 100 includes a body 110 which forms the outer surface of the hinge. Specifically, the body 110 includes a base 112, a support portion 114, and a hinge shaft 116. A screw hole is provided on the base 112, and the base 112 is connected to the door body or the box body of the refrigeration device by screws. The support portion 114 is provided on the base 112, and the hinge shaft 116 is provided on the support portion 114. The support portion 114 can provide positioning and support for the hinge shaft 116, and the support portion 114 can form a rotating swing arm between the base 112 and the hinge shaft 116.
[0059] Among them, the base 112 and the support portion 114 on the body 110 are integrally formed by die-casting. During the cooling process of the die-cast base 112 and support portion 114, thermal stress is likely to be generated, making it difficult to control the dimensional accuracy of the base 112 and the support portion 114. In particular, the perpendicularity of the base 112 and the support portion 114 cannot be guaranteed. Moreover, defects such as pores and inclusions are likely to appear in the die-cast base 112 and support portion 114. This defect easily causes the intersection area of the base 112 and the support portion 114 to be unable to withstand the rated torque, increasing the probability of bending or even breaking of the base 112 and the support portion 114 at the intersection area.
[0060] In response to this, an embedded component 120 is pre-embedded in the base 112 and the support portion 114 of this application. Specifically, the embedded component 120 is first placed in the mold, and the embedded component 120 is at least placed in the intersection area of the base 112 and the support portion 114. According to requirements, the embedded component 120 can also extend to other areas. Then, casting material is injected into the mold to integrally form the base 112 and the support portion 114 on the outside of the embedded component 120, so that the embedded component 120 can be smoothly embedded into the intersection area of the body 110 and the support portion 114.
[0061] By pre-embedding the embedded component 120 in the body 110 and the support portion 114, the fluidity of the metal casting material can be effectively improved during the die-casting process, reducing the probability of defects such as pores and inclusions in the base 112 and the support portion 114, thereby effectively enhancing the mechanical strength of the base 112 and the support portion 114. Moreover, the embedded component 120 pre-embedded in the intersection area of the base 112 and the support portion 114 can replace the body 110 and the support portion 114 to resist part of the torque, thereby enhancing the structural strength of the base 112 and the support portion 114.
[0062] It can be seen that on the one hand, the embedded component 120 can ensure the perpendicularity and dimensional accuracy between the base 112 and the support portion 114, reducing the subsequent compensation machining cost. On the other hand, the embedded component 120 can also reduce the probability of problems such as bending or even fracture of the support portion 114 during use through strength reinforcement, so as to improve the mechanical strength of the hinge mechanism 100 and reduce the failure rate. On the other hand, the embedded component 120 can also improve the load-bearing capacity of the hinge mechanism 100, enabling the hinge mechanism 100 to be applicable to door bodies with large weights and broadening the application range of the hinge mechanism 100. Thereby solving the technical problems existing in the foregoing related technologies, and further achieving the technical effects of improving the structural strength and dimensional accuracy of the hinge mechanism 100, reducing the failure rate of the hinge mechanism 100, and improving the yield rate of the hinge mechanism 100.
[0063] As Figure 2 and Figure 4 shown, in some technical solutions of the present utility model, optionally, the embedded component 120 includes: a first insert 122, the first insert 122 includes a first section 1222 and a second section 1224, the first section 1222 is disposed in the base 112, the second section 1224 is connected to the first section 1222, and a part of the second section 1224 is located in the support portion 114.
[0064] In this technical solution, the embedded component 120 at least includes the first insert 122. The position of the first insert 122 is divided into a first section 1222 and a second section 1224. Among them, the first section 1222 is disposed in the base 112, and the shape of the first section 1222 is adapted to the shape of the base 112 to enhance the strength reinforcement effect of the first section 1222 on the base 112. The second section 1224 is disposed in the support portion 114, and the first end of the second section 1224 is connected to the first section 1222. Similarly, the shape of the second section 1224 is adapted to the shape of the support portion 114 to enhance the strength reinforcement effect of the second section 1224 on the support portion 114.
[0065] Specifically, the connection portion between the first section 1222 and the second section 1224 corresponds to the intersection area of the base 112 and the support portion 114. During the die-casting process, the metal casting material is effectively filled into the intersection area of the base 112 and the support portion 114 under the guiding action of the first section 1222 and the second section 1224, so as to reduce the possibility of defects such as pores and inclusions in the intersection area of the base 112 and the support portion 114, and at the same time improve the perpendicularity of the base 112 and the support portion 114. Moreover, the connected first section 1222 and second section 1224 can resist part of the stress inside the base 112 and the support portion 114 instead of the base 112 and the support portion 114, thereby improving the structural strength of the base 112 and the support portion 114.
[0066] AsFigure 4 As shown, in some technical solutions of the present utility model, optionally, the thickness of the first section 1222 ( Figure 4 shown as D1 in) is greater than or equal to 2 mm and less than or equal to 5 mm; the thickness of the second section 1224 ( Figure 4 shown as D2 in) is greater than or equal to 2 mm and less than or equal to 5 mm.
[0067] In this technical solution, the first section 1222 is in a plate shape, and the thickness of the first section 1222 needs to be greater than or equal to 2 mm and less than or equal to 5 mm. By limiting the thickness of the first section 1222 to be greater than or equal to 2 mm, it can be ensured that the first section 1222 can provide effective reinforcement for the base 112, thereby improving the load-bearing capacity of the base 112 and reducing the probability of irreversible deformation of the base 112. By limiting the thickness of the first section 1222 to be less than or equal to 5 mm, on the one hand, the volume of the embedded component 120 can be reduced on the basis of meeting the structural reinforcement requirements, on the one hand, reducing the production cost, and on the other hand, providing convenient conditions for the miniaturization design and lightweight design of the hinge mechanism 100.
[0068] The second section 1224 is in a plate shape, and the thickness of the second section 1224 needs to be greater than or equal to 2 mm and less than or equal to 5 mm. By limiting the thickness of the second section 1224 to be greater than or equal to 2 mm, it can be ensured that the second section 1224 can provide effective reinforcement for the support part 114, thereby improving the load-bearing capacity of the support part 114 and reducing the probability of irreversible deformation of the support part 114. By limiting the thickness of the second section 1224 to be less than or equal to 5 mm, on the one hand, the volume of the embedded component 120 can be reduced on the basis of meeting the structural reinforcement requirements, on the one hand, reducing the production cost, and on the other hand, providing convenient conditions for the miniaturization design and lightweight design of the hinge mechanism 100.
[0069] As Figure 3 and Figure 5 shown, in some technical solutions of the present utility model, optionally, the first insert 122 is an L-shaped steel, or the first insert 122 is a T-shaped steel.
[0070] In this technical solution, the first insert 122 is obtained by cutting an L-shaped steel. Among the two perpendicular parts of the L-shaped steel, one part is embedded in the base 112, and the other part is embedded in the support part 114. The two perpendicular parts in the L-shaped steel have strong bending and torsion resistance capabilities, so as to replace the base 112 and the support part 114 to resist part of the bending and torsion moments, and the probability of irreversible deformation of the support part 114 and the base 112, thereby achieving the technical effects of improving the structural strength of the hinge mechanism 100 and reducing the failure rate of the hinge mechanism 100.
[0071] Similarly, the first insert 122 can also be obtained by cutting a T-shaped steel. Among the two perpendicular parts of the T-shaped steel, one part is embedded in the base 112, and the other part is embedded in the support portion 114. The two perpendicular parts of the T-shaped steel have strong bending and torsion resistance, so as to replace the base 112 and the support portion 114 to resist part of the bending and torsion moments, and reduce the probability of irreversible deformation of the support portion 114 and the base 112, thereby achieving the technical effects of improving the structural strength of the hinge mechanism 100 and reducing the failure rate of the hinge mechanism 100. Among them, compared with the L-shaped steel, the T-shaped steel has a stronger structural reinforcement effect on the base 112, and the L-shaped steel or the T-shaped steel can be selected as the embedded component 120 according to the weight requirement and the strength requirement of the base 112.
[0072] On the other hand, selecting the L-shaped steel and the T-shaped steel are standard parts that can be directly purchased. Obtaining the first insert 122 by cutting the L-shaped steel or the T-shaped steel can also eliminate the machining process of the first insert 122, thereby reducing the process complexity and production cost of the hinge mechanism 100.
[0073] Such as Figure 2 、 Figure 4 and Figure 6 shown, in some technical solutions of the present utility model, optionally, the embedded component 120 is an integral structure; the base 112 and the support portion 114 are an integral structure, and the base 112 and the support portion 114 jointly wrap the embedded component 120.
[0074] In this technical solution, the embedded component 120 is an integral structure, and the base 112 and the support portion 114 on the body 110 are integrally formed on the outside of the embedded component 120 by die-casting process. Specifically, first place the embedded component 120 in the mold, and the embedded component 120 is at least placed in the intersection area of the base 112 and the support portion 114. According to the requirement, the embedded component 120 can also extend to other areas. Then inject the casting material into the mold to integrally form the base 112 and the support portion 114 on the outside of the embedded component 120, so that the embedded component 120 can be smoothly embedded into the intersection area of the body 110 and the support portion 114.
[0075] Preparing the base 112 and the support portion 114 by die-casting forming process can reduce the process complexity of the hinge mechanism 100, is beneficial to improving the production efficiency of the hinge mechanism 100, and is beneficial to reducing the production cost of the hinge mechanism 100.
[0076] Moreover, by pre-embedding the embedded component 120 in the body 110 and the support portion 114, the fluidity of the metal casting material can be effectively improved during the die-casting process, and the probability of gas holes and inclusion defects in the base 112 and the support portion 114 can be reduced, thereby effectively enhancing the mechanical strength of the base 112 and the support portion 114. In addition, the embedded component 120 embedded in the intersection area of the base 112 and the support portion 114 can resist part of the moment instead of the body 110 and the support portion 114, thereby enhancing the structural strength of the base 112 and the support portion 114.
[0077] As Figure 4 shown, in some technical solutions of the present invention, optionally, the minimum distance ( Figure 4 shown as D3 in
[0078] ) between the embedded component 120 and the outer surface of the body 110 ranges from greater than or equal to 2 mm to less than or equal to 5 mm.
[0079] In this technical solution, the minimum distance between the embedded component 120 and the outer surface of the body 110 is the spacing between the embedded component 120 and the outer surface of the body 110, and this spacing needs to be greater than or equal to 2 mm and less than or equal to 5 mm. By defining that the spacing between the embedded component 120 and the outer surface of the body 110 is greater than or equal to 2 mm and less than or equal to 5 mm, on the one hand, it can avoid the embedded component 120 with too large volume from increasing the cost and weight of the hinge mechanism 100, and on the other hand, it can ensure the structural strength of the part of the body 110 outside the embedded component 120 and avoid the part of the body 110 with too thin thickness from being damaged by external forces.
[0080] As Figure 6 shown, in some technical solutions of the present invention, optionally, the embedded component 120 further includes: a second insert 124, and the second insert 124 is embedded in the hinge shaft 116.
[0081] In this technical solution, the embedded component 120 further includes a second insert 124. The second insert 124 is arranged inside the hinge shaft 116, the hinge shaft 116 is sleeved outside the second insert 124, or the hinge shaft 116 is integrally formed with the support portion 114 and the base 112 outside the second insert 124. The dimensional accuracy of the hinge shaft 116 directly affects the switching reliability of the door body. By pre-embedding the second insert 124 inside the hinge shaft 116, the dimensional error of the hinge shaft 116 can also be reduced, thereby improving the reliability and yield rate of the hinge mechanism 100. On the other hand, the second insert 124 arranged inside the hinge shaft 116 can share part of the bending moment for the hinge shaft 116, thereby enhancing the mechanical strength of the hinge mechanism 100 and reducing the possibility of the hinge shaft 116 being bent or even broken.
[0082] As Figure 6As shown, in some technical solutions of the present utility model, optionally, the second section 1224 is connected to the second insert 124.
[0083] In this technical solution, the first end of the second section 1224 is connected to the first section 1222, and the second end of the second section 1224 is connected to the second insert 124. By connecting the first insert 122 and the second insert 124 together, an integral internal skeleton capable of strengthening the base 112, the support portion 114, and the hinge shaft 116 can be formed inside the body 110, thereby enhancing the structural strength of the embedded component 120, enabling the embedded component 120 to share more bending and torsional moments for the body 110, further enhancing the mechanical strength of the body 110, and reducing the probability of irreversible deformation of the body 110.
[0084] In some technical solutions of the present utility model, optionally, the hardness of the embedded component 120 is greater than the hardness of the base 112 and the support portion 114.
[0085] In this technical solution, the hardness of the material of the embedded component 120 is greater than the hardness of the material of the base 112 and the hardness of the material of the support portion 114. By providing a harder embedded component 120 inside the body 110, the embedded component 120 can share more bending and torsional moments for the body 110, thereby further enhancing the mechanical strength of the hinge mechanism 100, reducing the probability of irreversible deformation of the hinge mechanism 100, further reducing the failure rate of the hinge mechanism 100, and broadening the applicable range of the hinge mechanism 100.
[0086] Specifically, the material of the embedded component 120 is carbon steel, and the materials of the base 112 and the support portion 114 include tin alloy and aluminum alloy.
[0087] The second aspect of the present utility model provides a refrigeration device, which includes: the hinge mechanism 100 in any of the above technical solutions; a box body, the box body is connected to one of the base 112 and the hinge shaft 116; a door body, the door body is connected to the other of the base 112 and the hinge shaft 116.
[0088] This technical solution defines a refrigeration device provided with the hinge mechanism 100 in any of the above technical solutions. Therefore, this refrigeration device has the advantages of the hinge mechanism 100 in any of the above technical solutions and can achieve the technical effects that the hinge mechanism 100 in any of the above technical solutions can achieve. To avoid repetition, it will not be elaborated here.
[0089] On this basis, the refrigeration device further includes a box body and a door body. The inside of the box body is used to store materials that need to be refrigerated. The box body includes an opening. The door body is hinged to the box body through the hinge mechanism 100. After assembly, the door body can rotate relative to the box body, thereby opening and closing the box body by rotating the door body.
