Description

Technical Field

[0001] The invention relates to the field of refrigerator hinges, and in particular to a refrigerator hinge capable of controlling a door opening angle. Background Art

[0002] As a product of the combination of traditional refrigerators and modern technology, smart refrigerators are gradually showing their unique value in various fields. Smart refrigerators, also known as data cabinets or smart refrigerators, not only have the refrigeration and freezing functions of traditional refrigerators, but can also improve management efficiency and optimize user experience through intelligent means. The opening and closing method of the refrigerator door is also an important part of the smart refrigerator. The refrigerator door with automatic induction opening and closing can bring a better experience to users. Most of the refrigerator doors in the existing technology need to be manually opened and closed by the user, and their intelligence level is not high, and the user experience still needs to be improved. Summary of the invention

[0003] In view of this, the present invention provides a refrigerator hinge capable of controlling the door opening angle in order to solve the above technical problems.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A refrigerator hinge capable of controlling a door opening angle comprises a box connecting member and a door connecting member rotatably connected via a hinge shaft, a linear drive mechanism being fixedly provided on the box connecting member, an output end of the linear drive mechanism being fixedly connected to the door connecting member, and a connection between the output end of the linear drive mechanism and the door connecting member and the hinge shaft being offset, the linear drive mechanism being used to lock the door connecting member and to drive the door connecting member to rotate around the hinge shaft.

[0006] In the above technical solution, through the precise control of the linear drive mechanism, the user can easily set and maintain the opening angle of the freezer door to meet the needs of different usage scenarios. Whether it is a small angle opening for quick access or a large angle opening for full display of internal items, precise adjustment can be achieved. Precise control of the door opening angle helps reduce the loss of cold air inside the freezer, especially when the freezer door is opened frequently. A small angle opening can quickly complete the access action and reduce the entry of hot air from the outside into the freezer, thereby maintaining a stable temperature inside the freezer, improving energy efficiency and extending the shelf life of food.

[0007] In addition, the design of the linear drive mechanism makes the door body more stable during opening and closing, reducing the risk of shaking or sudden closing caused by traditional hinge structures. At the same time, the locking function of the linear drive mechanism can ensure that the refrigerator door remains stable at a specific angle, preventing accidental opening and improving safety.

[0008] Furthermore, the linear drive mechanism is an electric push rod or a cylinder.

[0009] In the above technical solution, both the electric push rod and the air cylinder can efficiently convert the input energy into linear motion, thereby directly driving the door body connector to rotate around the hinge axis. This efficient energy conversion mechanism ensures the quick response and smooth operation of the refrigerator door, reducing energy waste.

[0010] Furthermore, the box body connecting member includes a first connecting plate and two first side panels arranged on opposite sides of the first connecting plate, the first connecting plate and the two first side panels are an integrally bent structure, the linear drive mechanism is fixed on the first connecting plate, and the door body connecting member is located between the two first side panels.

[0011] In the above technical solution, by designing the first connecting plate and the two first side plates as an integrated bending structure, not only the manufacturing process is simplified, but also the overall structural strength and stability of the box body connector are significantly improved. The design of the two first side plates cleverly wraps the linear drive mechanism inside, while providing a stable supporting environment for the door body connector and protecting the linear drive mechanism from external interference and damage.

[0012] Furthermore, a first cover plate is provided on the box connecting member, and the first cover plate is connected to the two first side plates.

[0013] In the above technical solution, after the first cover plate is connected to the two first side plates, a relatively closed space is formed, which effectively prevents dust, water vapor or other impurities from entering the area where the linear drive mechanism is located. It not only protects the linear drive mechanism from erosion by the external environment, but also extends its service life and reduces the risk of failure caused by pollution.

[0014] Furthermore, the door body connecting member includes a second connecting plate, two second side plates arranged on opposite sides of the second connecting plate, and a bottom plate connected between the two second side plates, the bottom plate and the second connecting plate are perpendicular to each other, and the output end of the linear drive mechanism is connected to the bottom plate.

[0015] In the above technical solution, by combining the second connecting plate, the two second side plates and the bottom plate into an integral structure, the door connecting member can have higher structural stability and bearing capacity when bearing the weight of the refrigerator door and various forces during the opening and closing process. In addition, the connection relationship between the various components is clear, which helps to ensure the accurate installation between the door connecting member and the box connecting member.

[0016] Furthermore, the second connecting plate, the bottom plate and the two second side plates are an integrally formed structure.

[0017] In the above technical solution, the one-piece structure eliminates the seams and connection points between the components, making the entire door body connector a solid whole, thereby improving its strength. At the same time, it simplifies the manufacturing process, reduces the steps of separate manufacturing and assembly, not only reduces production costs, but also improves production efficiency.

[0018] Furthermore, the two second side panels are located between the two first side panels and are respectively close to the two first side panels.

[0019] In the above technical solution, the positional relationship between the two first side panels and the two second side panels makes the entire hinge structure more compact in the lateral direction, which can effectively improve the stability of the door body connecting member when it rotates relative to the box body connecting member.

[0020] Furthermore, a second cover plate is provided on the door body connecting member, and the second cover plate is connected to the two second side plates.

[0021] In the above technical solution, the second cover plate provides an additional dustproof and protective barrier for key components inside the door body connector, such as the linear drive mechanism, which helps prevent dust, water vapor or other impurities from entering the interior, reduces the risk of failure due to contamination, and extends the service life of the components.

[0022] Furthermore, the box body connecting member is provided with a plurality of first mounting holes, and the door body connecting member is provided with a plurality of second mounting holes.

[0023] In the above technical solution, the design of the first mounting hole facilitates fixing the box connector on the refrigerator box, and the design of the second mounting hole facilitates fixing the door connector on the refrigerator door. At the same time, it allows the installer to select the most suitable installation position and angle according to the specific size, structure and installation environment of the refrigerator, thereby ensuring the stability and reliability of the hinge connection.

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0029] Please refer to Figure 1-Figure 3 , a preferred embodiment of the present invention is as follows.

[0030] A refrigerator hinge capable of controlling a door opening angle comprises a box connector 1 and a door connector 2 which are rotatably connected via a hinge shaft 3, a linear drive mechanism 4 being fixedly provided on the box connector 1, an output end of the linear drive mechanism 4 being fixedly connected to the door connector 2, and a connection between the output end of the linear drive mechanism 4 and the door connector 2 is offset from the hinge shaft 3, the linear drive mechanism 4 being used to lock the door connector 2 and to drive the door connector 2 to rotate around the hinge shaft 3.

[0031] In this embodiment, through the precise control of the linear drive mechanism 4, the user can easily set and maintain the opening angle of the refrigerator door to meet the needs of different usage scenarios. Whether it is a small angle opening for quick access or a large angle opening for full display of internal items, precise adjustment can be achieved. Precise control of the door opening angle helps to reduce the loss of cold air inside the refrigerator, especially when the refrigerator door is opened frequently, a small angle opening can quickly complete the action of taking things, reduce the outside hot air from entering the refrigerator, thereby maintaining a stable temperature inside the refrigerator, improving energy efficiency and extending the shelf life of food.

[0032] In addition, the design of the linear drive mechanism 4 makes the door body more stable during opening and closing, reducing the risk of shaking or sudden closing caused by the traditional hinge structure. At the same time, the locking function of the linear drive mechanism 4 can ensure that the refrigerator door remains stable at a specific angle, preventing accidental opening and improving safety in use.

[0033] Specifically, the linear drive mechanism 4 of this embodiment is an electric push rod or a pneumatic cylinder. The electric push rod and the pneumatic cylinder as the linear drive mechanism 4 provide different power source options. The electric push rod is driven by electricity and is suitable for environments with stable power supply. It has the advantages of fast response, precise control, and low noise. The pneumatic cylinder uses compressed air or hydraulic pressure as a power source, which is particularly suitable for occasions that require explosion-proof, waterproof or difficult to obtain electricity. It has the characteristics of simple structure and strong durability.

[0034] Both the electric push rod and the air cylinder can efficiently convert the input energy into linear motion, thereby directly driving the door body connector 2 to rotate around the hinge axis 3. This efficient energy conversion mechanism ensures the quick response and smooth operation of the refrigerator door, reducing energy waste.

[0035] In this embodiment, the box body connector 1 includes a first connecting plate 11 and two first side plates 12 arranged on opposite sides of the first connecting plate 11. The first connecting plate 11 and the two first side plates 12 are an integrally bent structure. The linear drive mechanism 4 is fixed on the first connecting plate 11, and the door body connector 2 is located between the two first side plates 12. The box body connector 1 is an overall "U"-shaped structure.

[0036] By designing the first connecting plate 11 and the two first side plates 12 as an integral bending structure, not only the manufacturing process is simplified, but also the overall structural strength and stability of the box connector 1 are significantly improved. The design of the two first side plates 12 cleverly wraps the linear drive mechanism 4, while providing a stable supporting environment for the door connector 2 and protecting the linear drive mechanism 4 from external interference and damage.

[0037] The box connector 1 of this embodiment is also provided with a first cover plate 5, which is connected to the two first side plates 12, and the first cover plate 5 is a detachable structure. After the first cover plate 5 is connected to the two first side plates 12, a relatively closed space is formed, which effectively prevents dust, water vapor or other impurities from entering the area where the linear drive mechanism 4 is located, not only protecting the linear drive mechanism 4 from erosion by the external environment, but also extending its service life and reducing the risk of failure caused by pollution.

[0038] In this embodiment, the door body connecting member 2 includes a second connecting plate 21, two second side plates 22 arranged on opposite sides of the second connecting plate 21, and a bottom plate 23 connected between the two second side plates 22, the bottom plate 23 and the second connecting plate 21 are perpendicular to each other, and the output end of the linear drive mechanism 4 is connected to the bottom plate 23. Among them, the second connecting plate 21, the bottom plate 23 and the two second side plates 22 are an integrally formed structure.

[0039] By combining the second connecting plate 21, the two second side plates 22 and the bottom plate 23 into an integral structure, the door body connector 2 can have higher structural stability and bearing capacity when bearing the weight of the refrigerator door and various forces during the opening and closing process. In addition, the connection relationship between the various components is clear, which helps to ensure the precise installation between the door body connector 2 and the box body connector 1. In addition, the one-piece molding structure eliminates the seams and connection points between the components, making the entire door body connector 2 a solid whole, thereby improving its strength. At the same time, it also simplifies the manufacturing process and reduces the steps of separate manufacturing and assembly, which not only reduces production costs but also improves production efficiency.

[0040] In this embodiment, the two second side panels 22 are located between the two first side panels 12 and are respectively close to the two first side panels 12. The hinge shaft 3 is used to connect the two first side panels 12 and the two second side panels 22. The output end of the linear drive mechanism 4 is fixed on the bottom plate 23 and has a certain offset distance with the hinge shaft 3, so that the door body connecting member 2 can be rotated around the hinge shaft 3 while pushing the bottom plate 23. In addition, the positional relationship between the two first side panels 12 and the two second side panels 22 makes the entire hinge structure more compact in the lateral direction, which can effectively improve the stability of the door body connecting member 2 when it rotates relative to the box body connecting member 1.

[0041] In this embodiment, the door body connector 2 is further provided with a second cover plate 6, which is connected to the two second side plates 22, and is a detachable structure. The second cover plate 6 provides an additional dustproof and protective barrier for key components inside the door body connector 2, such as the linear drive mechanism 4, which helps prevent dust, water vapor or other impurities from entering the interior, reduces the risk of failure due to contamination, and prolongs the service life of the components.

[0042] In this embodiment, a plurality of first mounting holes 111 are provided on the box body connector 1, and a plurality of second mounting holes 211 are provided on the door body connector 2. The first mounting holes 111 are located on the first connecting plate 11, and the second mounting holes 211 are located on the second connecting plate 21. The design of the first mounting holes 111 facilitates fixing the box body connector 1 on the refrigerator box body, and the design of the second mounting holes 211 facilitates fixing the door body connector 2 on the refrigerator door body, and allows the installer to select the most suitable installation position and angle according to the specific size, structure and installation environment of the refrigerator, thereby ensuring the stability and reliability of the hinge connection.
