Detailed Implementation

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0030] Please see Figure 1This application provides a hinge device 100 and a thermally insulated storage device 1000 equipped with the hinge device 100. In this embodiment, the thermally insulated storage device 1000 is a device capable of maintaining the internal storage space 921 within a certain temperature range. The thermally insulated storage device 1000 is generally shaped like a storage cabinet or storage box. In this embodiment, the thermally insulated storage device 1000 can be an ice maker, which may include components such as a compressor, evaporator, and condenser. The condenser can lower the temperature of the liquid and form ice. In other embodiments, the thermally insulated storage device 1000 can be a refrigerator, which may include components such as a compressor, evaporator, and condenser. The condenser works in conjunction with the storage space 921 to provide cooling to the storage space 921, enabling the thermally insulated storage device 1000 to have the function of refrigerating food, medicine, etc. In other embodiments, the heat-insulating storage device 1000 can also be an oven, which may include structures such as heating elements. The heating elements cooperate with the storage space 921 to provide heat to the storage space 921 to dry or bake food. In still other embodiments, the heat-insulating storage device 1000 may also include electrical appliances such as steam ovens, dishwashers, and sterilizers. Different types of heat-insulating storage devices 1000 are equipped with different functional components to give the heat-insulating storage device 1000 specific functions.

[0031] In this embodiment, the insulated storage device 1000 is mounted on a horizontal application surface. In other embodiments, it can be installed on a building facade. The overall structure of the insulated storage device 1000 is roughly cabinet-shaped. Specifically, the insulated storage device 1000 in this application includes a cabinet body 900 and a cabinet door 800. The cabinet body 900 defines the storage space 921 mentioned above, and the storage space 921 has a large opening 9211 for users to retrieve and place food. In this embodiment, the cabinet door 800 is rotatably connected to the cabinet body 900, for example, through a pivot or hinge. In this embodiment, the cabinet door 800 rotates about a horizontal axis. In some other embodiments, the cabinet door 800 can rotate relative to the cabinet body 900 about a vertical axis. The cabinet door 800 is used to cover the storage space 921. When the cabinet door 800 is closed to the cabinet body 900, the cabinet door 800 covers the opening 9211 on the cabinet body 900 to cover the storage space 921. In this embodiment, the insulated storage device 1000 may also include a sealing element (not shown in the figure). The sealing element is connected to the cabinet door 800 and has a ring-shaped structure. When the cabinet door 800 is closed to the cabinet body 900, the cabinet door 800 and the cabinet body 900 together clamp the sealing element. The sealing element is arranged around the periphery of the opening 9211 to improve the sealing performance of the storage space 921.

[0032] Please see Figure 1 and Figure 2In this embodiment, the insulated storage device 1000 further includes a hinge device 100, which is connected between the cabinet door 800 and the cabinet body 900. The hinge device 100 can improve the stability of the connection between the cabinet door 800 and the cabinet body 900. In this embodiment, the insulated storage device 1000 is equipped with at least two hinge devices 100 for each cabinet door 800. The cabinet door 800 has two ends on the rotation axis of the cabinet door 800, and the two hinge devices 100 are respectively connected to the two ends of the cabinet door 800 to improve the connection stability between the cabinet door 800 and the cabinet body 900. In this embodiment, the cabinet body 900 includes an insulated inner liner 920 and a shell 910. The shell 910 is the external structure and main structure of the insulated storage device 1000. The shell 910 is a cavity structure, and the insulated inner liner 920 is installed inside the shell 910. The insulated inner liner 920 is provided with the storage space 921 mentioned above. In this embodiment, the cabinet door 800 is rotatably connected to the housing 910. When the cabinet door 800 is closed, it covers the insulated inner liner 920. In this embodiment, an accommodating space (not shown in the figure) is provided between the housing 910 and the insulated inner liner 920. This reduces direct contact between the housing 910 and the insulated inner liner 920, preventing damage to the structure of the insulated inner liner 920 from large impact forces when the housing 910 is subjected to collisions. In this embodiment, the hinge device 100 is disposed within the accommodating space. The hinge device 100 can be connected to the insulated inner liner 920 or to the housing 910. When the cabinet 900 and the cabinet door 800 are closed, the hinge device 100 is hidden inside the cabinet 900, protecting the hinge device 100 and preventing it from colliding or abutting with other structures. This results in a clean and aesthetically pleasing appearance for the insulated storage device 1000. In this embodiment, the insulated storage device 1000 further includes an insulating filler (not shown in the figure), which is disposed within the accommodating space. The insulating filler can be foam or expanded foam to provide an additional layer of insulation for the storage space 921. In this embodiment, the insulating filler can provide installation and movement space for the hinge device 100 to avoid collision or contact between the hinge device 100 and the insulating filler.

[0033] This application does not limit the application device to which the hinge device 100 is applied. The application device includes at least two structures, and the hinge device 100 is used to connect the two structures to improve the stability of the connection between them. The two structures include a first structure and a second structure, and the second structure is capable of flipping relative to the first structure. In this embodiment, the second structure can be flipped using the hinge device 100 or other accessories (such as hinges). In this embodiment, the hinge device 100 is applied to an insulated storage device 1000. The cabinet 900 of the insulated storage device 1000 corresponds to the first structure, and the cabinet door 800 corresponds to the second structure. In the following text, the cabinet 900 and the first structure can be interchanged, and the cabinet door 800 and the second structure can be interchanged.

[0034] Please see Figure 3 In this embodiment, the hinge device 100 includes a limiting member 10, a rotating shaft 30, and a connecting member 20. The limiting member 10 is installed on a first structure (e.g., the cabinet 900 mentioned above), the rotating shaft 30 is installed on a second structure (e.g., the cabinet door 800 mentioned above), and the connecting member 20 connects the limiting member 10 and the rotating shaft 30. Specifically, in the insulated storage device 1000 of this embodiment, the limiting member 10 is installed on the cabinet 900, the rotating shaft 30 is installed on the cabinet door 800, and the connecting member 20 connects the limiting member 10 and the rotating shaft 30 to connect the cabinet door 800 and the cabinet 900. In this embodiment, one end of the connecting member 20 is connected to the rotating shaft 30, and the connecting member 20 is rotatably connected to the cabinet door 800 through the rotating shaft 30. The limiting member 10 is provided with a limiting groove 14. The other end of the connecting member 20 is movably engaged with the limiting member 10. The other end of the connecting member 20 can move relative to the limiting member 10 along the extending direction of the limiting groove 14, so that the connecting member 20 is in a movable state, allowing the cabinet door 800 to still have the ability to flip relative to the cabinet body 900. In actual application scenarios, when the cabinet door 800 is flipped relative to the cabinet body 900, the cabinet door 800 can drive the connecting member 20 (the other end) to move under the guidance of the limiting groove 14.

[0035] In this embodiment, there is friction between the main body structure of the limiting groove 14 (i.e., the limiting member 10) and the connecting member 20. This friction restricts the opening or closing of the cabinet door 800, preventing excessive movement of the cabinet door 800 relative to the cabinet body 900 and preventing the cabinet door 800 from easily shaking. In this embodiment, the extension length of the limiting groove 14 is limited, and the limiting member 10 can limit the opening degree of the cabinet door 800 relative to the cabinet body 900, preventing the cabinet door 800 from opening too wide and preventing deformation of the cabinet door 800 and the cabinet body 900. In this embodiment, the surface of the cabinet 900 facing the cabinet door 800 is approximately flat, and the surface of the cabinet door 800 facing the storage space 921 is also approximately flat. The angle between the surface of the cabinet 900 facing the cabinet door 800 and the surface of the cabinet door 800 facing the storage space 921 is defined as the opening angle. The opening angle is at its maximum when the cabinet door 800 is fully open. The maximum value of the opening angle can be set to be greater than or equal to 75° or less than or equal to 85°, for example, 75°, 78°, 80°, 83°, 85°, etc.

[0036] Please see Figure 3 and Figure 4 In this embodiment, the limiting groove 14 includes a first guide section 141 and a second guide section 142, with the extension directions of the first guide section 141 and the second guide section 142 being different. In practical applications, the extension directions of the first guide section 141 and the second guide section 142 are different, so that the frictional force between the connector 20 and the limiting member 10 when the first guide section 141 moves is significantly different from the frictional force between the connector 20 and the limiting member 10 when the second guide section 142 moves. When the hinge device 100 is applied to the insulated storage equipment 1000, the external force applied by the user to the cabinet door 800 when the connector 20 moves in the first guide section 141 is significantly different from the external force applied by the user to the cabinet door 800 when the connector 20 moves in the second guide section 142. In this embodiment, when the connector 20 is engaged with the first guide section 141, the opening angle range of the cabinet door 800 relative to the cabinet body 900 can be set to [0°, 45°], and when the connector 20 is engaged with the second guide section 142, the opening angle range of the cabinet door 800 relative to the cabinet body 900 can be set to (45°, 85°). In actual application scenarios, the external force applied by the user when the connector 20 is engaged with the first guide section 141 is significantly different from the external force applied by the user when the connector 20 is engaged with the second guide section 142. This changes the user's feel when opening the door, prompting the user that the cabinet door 800 has entered the next stage of opening. The user can understand the degree of opening of the cabinet door 800 by perceiving the ease or difficulty of opening the cabinet door 800, which helps remind the user to control the force.

[0037] In summary, this embodiment provides a hinge device 100, which is applied to an application device including a first structure and a second structure. The hinge device 100 connects the first structure and the second structure, and the second structure is capable of flipping relative to the first structure. The hinge device 100 includes a limiting member 10, a connecting member 20, and a rotating shaft 30. The limiting member 10 is mounted on the first structure, and the rotating shaft 30 is mounted on the second structure. The limiting member 10 is provided with a limiting groove 14. One end of the connecting member 20 is connected to the rotating shaft 30 to be rotatably connected to the second structure, and the other end is movably engaged with the limiting groove 14 of the limiting member 10. When the second structure is flipped relative to the first structure, the second structure can drive the connecting member 20 to slide under the guidance of the limiting groove 14.

[0038] In this embodiment, the limiting groove 14 includes a first guide segment 141 and a second guide segment 142 with different extending directions. The external force applied by the user to make the connector 20 cooperate with the first guide segment 141 is different from the external force applied to make the connector 20 cooperate with the second guide segment 142. This causes the external force applied by the user to push or pull the second structure relative to the first structure to have a certain degree of jump, so that there are two kinds of feel. The change of feel can indicate to the user that the degree of change of the posture of the first structure relative to the first structure has entered different stages, and can also remind the user to pay attention to the force applied and avoid improper force application.

[0039] In this embodiment, the second guide segment 142 is closer to the cabinet door 800 than the first guide segment 141. The straight line extending in the direction of the first guide segment 141 is approximately perpendicular to the surface of the cabinet body 900 facing the cabinet door 800. The second guide segment 142 extends in the direction towards the connection between the cabinet door 800 and the cabinet body 900. With this configuration, the movement path of the connector 20 is relatively simple, which can avoid the connector 20 from jamming or getting stuck with the limiting member 10, and the movement space required for the connector 20 is also smaller. In other embodiments, the extension directions of the first guide segment 141 and the second guide segment 142 can be set in other forms, and this embodiment does not impose specific limitations. In other embodiments, the cabinet door 800 can be opened to a greater extent, for example, the maximum opening angle can reach 140°, 145°, etc. In such embodiments, the limiting groove 14 can include multiple guide segments with different extension directions and connected in sequence. The limiting groove 14 can also include multiple first guide segments 141 or multiple second guide segments 142. The multiple first guide segments 141, multiple second guide segments 142 and other guide segments with extension directions can be arbitrarily combined and connected.

[0040] Please see Figure 5In this embodiment, the limiting groove 14 is a through groove, passing through both opposite sides of the limiting member 10. The hinge device 100 in this embodiment also includes a clamping assembly 40, which is connected to the connecting member 20. The clamping assembly 40 is movably inserted through the limiting groove 14 and connects the limiting member 10 and the connecting member 20. In this embodiment, the connecting member 20 is movably connected to the limiting member 10 via the clamping assembly 40, enabling a movable fit between the connecting member 20 and the limiting groove 14. The clamping assembly 40 passing through the limiting member 10 ensures a relatively stable connection between the connecting member 20 and the limiting member 10, preventing loss of fit between them. In other embodiments, the limiting groove 14 can be a groove with a bottom wall, and the clamping assembly 40 is embedded in the limiting groove 14. In other embodiments, the limiting groove 14 can also be a guide rail groove, with the structure of the clamping assembly 40 or the connecting member 20 specifically configured to correspond to the guide rail groove.

[0041] Please see Figure 3 and Figure 6 In this embodiment, the clamping assembly 40 passes through the limiting member 10, so at least a portion of the structure of the clamping assembly 40 is located on the side of the limiting member 10 away from the connector 20. To accommodate this portion of the structure, the heat-insulating inner liner 920 in this embodiment is provided with a mounting groove 922. The limiting member 10 is connected to the heat-insulating inner liner 920, and the limiting groove 14 communicates with the mounting groove 922. A portion of the structure of the clamping assembly 40 is accommodated within the mounting groove 922. In this embodiment, the mounting groove 922 has a mounting step 923 at its opening. The mounting step 923 is recessed relative to the surface of the heat-insulating inner liner 920. The limiting member 10 is embedded in the mounting groove 922 and abuts against the mounting step 923. In this embodiment, the sidewall of the mounting groove 922 has a certain limiting effect on the limiting member 10, facilitating the installation of the limiting member 10 into the mounting groove 922.

[0042] Please see Figure 5 and Figure 7 In this embodiment, the clamping assembly 40 includes a through-hole member 41 and an anti-detachment member 42. The through-hole member 41 passes through the connector 20 and the limiting groove 14 respectively. In this embodiment, the through-hole member 41 passes through the connector 20 first, and then through the limiting groove 14. The anti-detachment member 42 is located on the side of the limiting member 10 opposite to the connector 20, and is connected to the through-hole member 41 to prevent the through-hole member 41 from detaching from the limiting groove 14. In other embodiments, the through-hole member 41 passes through the limiting groove 14 first, and then through the connector 20. The anti-detachment member 42 is located on the side of the connector 20 opposite to the limiting member 10 and is connected to the through-hole member 41. In this embodiment, the anti-detachment component 42 can be a pin or nut, etc. The size of the anti-detachment component 42 is larger than the width of the limiting groove 14. The anti-detachment component 42 cannot move from one side of the limiting component 10 to the other side of the limiting component 10 via the limiting groove 14, so that the insert 41 remains inserted in the limiting groove 14.

[0043] In this embodiment, the through-feed member 41 includes an abutment portion 411 and a pin 412 connected to each other. The pin 412 passes through the connector 20 and the limiting groove 14 in sequence. The anti-detachment member 42 is connected to the pin 412. The anti-detachment member 42 and the abutment portion 411 are located at both ends of the pin 412, and the anti-detachment member 42 and the abutment portion 411 are located on both sides of the limiting member 10. The connector 20 is located between the limiting member 10 and the abutment portion 411. In this embodiment, the connector 20 is provided with a through hole for the pin 412 to pass through. The size of the abutment portion 411 is larger than the size of the through hole on the connector 20, so that the through-feed member 41 and the connector 20 are stably connected, and the connector 20 and the limiting member 10 maintain a movable fit relationship. In practical applications, there is friction between the through-piece 41 and the inner wall of the limiting groove 14, and there is a certain amount of friction between the connector 20 and the limiting piece 10, so as to increase the difficulty of opening the cabinet door 800 and avoid excessive mobility of the cabinet door 800.

[0044] In this embodiment, the clamping assembly 40 further includes an elastic element 43, which elastically abuts against the limiting member 10 and the anti-detachment member 42, such that one side of the connecting member 20 abuts against the limiting member 10 and the other side abuts against the abutting portion 411, with the limiting member 10 and the abutting portion 411 jointly clamping the connecting portion. In this embodiment, the elastic element 43 increases the friction between the connecting member 20 and the limiting member 10, effectively increasing the difficulty of opening the cabinet door 800 to create a damping sensation. In this embodiment, the elastic element 43 may include an elastic washer, which is sleeved on the through member 41, with both ends of the elastic washer abutting against the anti-detachment member 42 and the limiting member 10, respectively. In other embodiments, the elastic element 43 may include a metal spring, a spring, or an elastic sleeve, etc. In this embodiment, the clamping assembly 40 further includes a gasket 44, which is circumferentially disposed around the through member 41. The gasket 44 is located between the elastic member 43 and the limiting member 10. In this embodiment, one end of the elastic member 43 abuts against the anti-detachment member 42, and the other end abuts against the gasket 44 so that the gasket 44 abuts against the limiting member 10. The size of the gasket 44 is larger than the width of the limiting groove 14, and the gasket 44 can span across both sides of the limiting groove 14 in the extending direction to prevent the end of the elastic member 43 from being embedded in the limiting groove 14, so that the connecting member 20 can slide smoothly under the guidance of the limiting groove 14. In this embodiment, the contact area between the gasket 44 and the limiting member 10 is large, and the friction is also large, further increasing the resistance.

[0045] Please see Figure 4In this embodiment, the limiting member 10 includes a first guide portion 11 and a second guide portion 12, with the first guide portion 11 connected to the second guide portion 12. In this embodiment, the second guide portion 12 is closer to the cabinet door 800 than the first guide portion 11. A first guide segment 141 is disposed on the first guide portion 11, and a second guide segment 142 is disposed on the second guide portion 12. In this embodiment, the first guide portion 11 extends along a first straight line A, and the second guide portion 12 extends along a second straight line B, with the first straight line A intersecting the second straight line B. In this embodiment, the direction defined by the first straight line A is approximately the same as the extension direction of the first guide segment 141, and the direction defined by the second straight line B is approximately the same as the extension direction of the second guide segment 142. In this embodiment, the included angle between the first straight line A and the second straight line B is greater than 0° or less than or equal to 30°, for example, it can be 5°, 10°, 15°, 23°, 30°, etc.

[0046] In this embodiment, the connector 20 and the limiting member 10 are two independent structures, and the connector 20 and the limiting member 10 slide relative to each other through a clearance fit. In this embodiment, the limiting member 10 also includes a tight-fitting part 13, which is connected between the first guide part 11 and the second guide part 12. In this embodiment, the size of the fit clearance between the connector 20 and the tight-fitting part 13 is smaller than the size of the fit clearance between the connector 20 and the first guide part 11, and the size of the fit clearance between the connector 20 and the tight-fitting part 13 is smaller than the size of the fit clearance between the connector 20 and the second guide part 12. In actual application scenarios, the connector 20 and the gasket 44 jointly clamp the limiting member 10 under the elastic action of the elastic member 43. The connector 20 and the limiting member 10 can slide relative to each other and generate friction, and the gasket 44 and the limiting member 10 can slide relative to each other and generate friction. The external force applied by the user can cause the connector 20 to slide if it can overcome multiple friction forces. During the process of the connector 20 switching from the first guide section 141 to the second guide section 142, the connector 20 needs to pass over the fastening part 13. The fit gap between the connector 20 and the fastening part 13 is small. During the process of passing over the fastening part 13, the fastening part 13 compresses the elastic element 43 through the gasket 44, causing the elastic element 43 to contract. The elastic element 43 provides a greater elastic force to the gasket 44 to increase the friction between the gasket 44 and the limiting member 10, and the friction between the connector 20 and the limiting member 10. Therefore, during the process of the connector 20 passing over the fastening part 13, the user needs to apply a greater force to the cabinet door 800. When the user realizes that more force needs to be applied, they can further realize that the connector is about to enter the second guide section 142 from the first guide section 141, and the opening degree of the cabinet door 800 is about to enter the next stage.

[0047] Please see Figure 8In this embodiment, the first guide portion 11, the second guide portion 12, and the fastening portion 13 are a single integrated structure connected in sequence. For example, a stamping process is used to make the surfaces of the first guide portion 11 and the second guide portion 12 lie on the same plane, so that the fastening portion 13 protrudes relative to the first guide portion 11 in a direction perpendicular to the plane of the limiting member 10, thereby causing the limiting member 10 to partially protrude. In other embodiments, the first guide portion 11 and the second guide portion 12 are directly connected, and the fastening portion 13 may include a protrusion structure disposed on the first guide portion 11 and the second guide portion 12.

[0048] This embodiment provides a hinge device 100, which is applied to an application device including a first structure and a second structure. The hinge device 100 connects the first structure and the second structure, and the second structure is capable of flipping relative to the first structure. The hinge device 100 includes a limiting member 10, a connecting member 20, and a rotating shaft 30. The limiting member 10 is mounted on the first structure, and the rotating shaft 30 is mounted on the second structure. The limiting member 10 has a limiting groove 14. One end of the connecting member 20 is connected to the rotating shaft 30 to be rotatably connected to the second structure, and the other end is movably engaged with the limiting groove 14 of the limiting member 10. When the second structure is flipped relative to the first structure, the second structure can drive the connecting member 20 to slide under the guidance of the limiting groove 14.

[0049] In this embodiment, the limiting groove 14 includes a first guide segment 141 and a second guide segment 142 with different extending directions. The external force applied by the user to make the connector 20 cooperate with the first guide segment 141 is different from the external force applied to make the connector 20 cooperate with the second guide segment 142. This causes the external force applied by the user to push or pull the second structure relative to the first structure to have a certain degree of jump, so that there are two kinds of feel. The change of feel can indicate to the user that the degree of change of the posture of the first structure relative to the first structure has entered different stages, and can also remind the user to pay attention to the force applied and avoid improper force application.
