[0030] The present application provides a hinge mechanism 100. Figures 1 to 4 , Figure 1 A schematic diagram of the structure of an implementation mode of the refrigeration equipment provided in this application; Figure 2 yes Figure 1 Enlarged view of part A in the middle;

[0031] Figure 3 A schematic structural diagram of another embodiment of the refrigeration equipment provided in this application; Figure 4 yes Figure 3Enlarged view of the middle B part. The hinge mechanism 100 includes a hinge seat 110, a self-locking member 120 and a hinge body 130. The hinge body 130 is connected between the hinge seat 110 and the self-locking member 120. The hinge seat 110 is used to be arranged on one of the device body 150 to be installed and the device door body 160 to be installed, so as to install the hinge body 130 on one of the device body 150 to be installed and the device door body 160 to be installed. The self-locking member 120 is used to be arranged on the other of the device body 150 to be installed and the device door body 160 to be installed, so as to install the hinge body 130 on the other of the device body 150 to be installed and the device door body 160 to be installed. The self-locking member 120 is also used to engage with the hinge seat 110 when the device door body 160 to be installed is in a closed state relative to the device body 150 to be installed, so as to lock the device door body 160 to be installed.

[0032] In some embodiments, the hinge base 110 is used to be set on one of the device body 150 to be installed and the device door 160 to be installed by riveting, bonding, bolting, magnetic adsorption connection or snap connection, but is not limited thereto. The embodiment of the present application takes the hinge base 110 as an example of being set on the device body 150 to be installed and the self-locking member 120 as an example of being set on the device door 160 to be installed.

[0033] The hinge mechanism 100 can be applied to a refrigeration device 1000. The device to be installed can be the refrigeration device 1000. The device body 150 to be installed can be the box 200 of the refrigeration device 1000. The device door 160 to be installed can be the door 300 of the refrigeration device 1000. The refrigeration device can be a refrigerator, for example, the refrigeration device 1000 can be a built-in refrigerator, a cross-door refrigerator or a French refrigerator, but is not limited thereto. In some embodiments, the device to be installed can be a wardrobe, a cabinet, a water dispenser or a microwave oven, but is not limited thereto.

[0034] The hinge body 130 is connected between the hinge seat 110 and the self-locking member 120. The hinge body 130 includes a first connecting rod 131 and a second connecting rod 132. The first connecting rod 131 is rotatably connected to the second connecting rod 132. One end of the first connecting rod 131 away from the second connecting rod 132 is rotatably arranged on the hinge seat 110. One end of the second connecting rod 132 away from the first connecting rod 131 is rotatably arranged on the self-locking member 120.

[0035] It can be understood that the first connecting rod 131 is rotatably connected to the second connecting rod 132, and the first connecting rod 131 is rotatably connected to the hinge seat 110, and the second connecting rod 132 is rotatably connected to the self-locking member 120. When the door body 160 of the equipment to be installed is opened relative to the main body 150 of the equipment to be installed, the first connecting rod 131 and the second connecting rod 132 rotate relative to the main body 150 of the equipment to be installed.

[0036] When it is necessary to open the door 160 of the device to be installed, the door 160 of the device to be installed can be pulled to drive the hinge body 130 to rotate, so that the door 160 of the device to be installed can be opened relative to the device body 150. The hinge mechanism 100 has a simple structure and is easy to operate. In addition, the setting of the self-locking member 120 can also prevent the door 160 of the device to be installed from automatically opening when it is closed relative to the device body 150.

[0037] The self-locking member 120 is used to engage with the hinge seat 110 when the door body 160 of the device to be installed is in a closed state relative to the main body 150 of the device to be installed, so as to lock the door body 160 of the device to be installed and prevent the door body 160 of the device to be installed from automatically opening when it is in a closed state relative to the main body 150 of the device to be installed. When it is necessary to open the door body 160 of the device to be installed relative to the main body 150 of the device to be installed, the door body 160 of the device to be installed is pulled away from the main body 150 of the device to be installed, so that the self-locking member 120 and the hinge seat 110 can be disengaged. In addition, when the door body 160 of the device to be installed is closed to a preset angle relative to the main body 150 of the device to be installed, the self-locking member 120 can provide the door body 160 of the device to be installed with a restoring force that automatically drives the door body 160 of the device to be installed to close relative to the main body 150 of the device to be installed. Under the action of the restoring force, the door body 160 of the device to be installed can be automatically closed relative to the main body 150 of the device to be installed.

[0038] For the convenience of description, in the following description, the first position state of the first connecting rod 131 and the second connecting rod 132 is defined as the state of the first connecting rod 131 and the second connecting rod 132 when the door body 160 of the equipment to be installed is in a closed state relative to the main body 150 of the equipment to be installed; the second position state of the first connecting rod 131 and the second connecting rod 132 is defined as the state of the first connecting rod 131 and the second connecting rod 132 when the door body 160 of the equipment to be installed is opened to the maximum extent relative to the main body 150 of the equipment to be installed.

[0039] In some embodiments, the first connecting rod 131 and the second connecting rod 132 can rotate relative to each other to a first position state and a second position state. When the first connecting rod 131 and the second connecting rod 132 rotate relative to each other to the first position state, the door body 160 of the device to be installed is in a closed state relative to the body 150 of the device to be installed, that is, the angle of the door body 160 of the device to be installed relative to the body 150 of the device to be installed is 0°. At this time, the hinge body 130 is in a folded state, and the first connecting rod 131 and the second connecting rod 132 are at least partially stacked. In the process of the first connecting rod 131 and the second connecting rod 132 rotating relative to each other from the first position state to the second position state, the hinge body 130 gradually unfolds, the angle D between the first connecting rod 131 and the second connecting rod 132 gradually increases, and the door body 160 of the device to be installed is opened relative to the body 150 of the device to be installed. When the first connecting rod 131 and the second connecting rod 132 rotate relative to each other to the second position, the angle of the door body 160 of the equipment to be installed relative to the main body 150 of the equipment to be installed reaches the maximum, the door body 160 of the equipment to be installed opens to the maximum angle relative to the main body 150 of the equipment to be installed, the maximum angle is greater than or equal to 180°, and the angle D between the first connecting rod 131 and the second connecting rod 132 reaches the maximum.

[0040] By making the first connecting rod 131 and the second connecting rod 132 rotate relative to each other to the second position, the door 160 of the device to be installed is opened to the maximum angle relative to the device body 150 to avoid the door 160 of the device to be installed occupying the space around the device body 150, thereby improving the user experience.

[0041] Please also read Figure 5 , Figure 5 This is a schematic diagram of a hinge mechanism provided by the present application. It can be understood that Figure 5 1 is a structural diagram of the hinge mechanism 100 when the first link 131 and the second link 132 are relatively rotated to the first position. When the first link 131 and the second link 132 are relatively rotated to the first position, the angle D between the first link 131 and the second link 132 is an acute angle, and the connection between the first link 131 and the second link 132 is spaced from the self-locking member 120 to avoid interference between the hinge body 130 and the self-locking member 120.

[0042] In some embodiments, when the first link 131 and the second link 132 rotate relative to each other to the first position, the angle D between the first link 131 and the second link 132 is 40°-50°. For example, the angle D between the first link 131 and the second link 132 can be 40°, 41.5°, 42°, 42.5°, 42.75°, 43°, 43.6°, 44°, 44.3°, 44.5°, 44.85°, 45°, 45.5°, 45.6°, 45.8°, 46°, 46.3°, 46.39°, 46.4°. , 46.5°, 46.8°, 47°, 47.35°, 47.88°, 48°, 48.5°, 48.9°, 49°, 49.5°, 50°, etc., or a range consisting of any two of the above values, for example, it can be 40°-42°, 42.75°-44°, 44.5°-45.6°, 45.8°-46.39°, 46.4°-48°, 48.5°-50°, etc., according to actual needs, as long as the angle D between the first connecting rod 131 and the second connecting rod 132 is in the range of 40°-50°.

[0043] Please continue reading Figure 2 , when the first link 131 and the second link 132 are relatively rotated to the second position, the angle D between the first link 131 and the second link 132 is an obtuse angle. In some embodiments, when the first link 131 and the second link 132 are relatively rotated to the second position, the angle D between the first link 131 and the second link 132 is 95°-105°. For example, the angle D between the first link 131 and the second link 132 can be 95°, 95.5°, 95.8°, 96°, 96.75°, 97°, 97.6°, 97.85°, 98°, 98.53°, 98.8°, 99°, 99.5°, 99.7°, 99.76°, 99.85°, 100°, 100.39°, 100.4°, 100.5°, 100.8°, 101°, 101.35°, 101.88°, 102°, 102.5°, 102.9°, 103°, 103.5°, 103.8°, 104°, 104.5°, 105°, etc., or a range consisting of any two of the above values, for example, it can be 95°-97°, 97.6°-99.7°, 99.76°-100.5°, 101°-103°, 103.5°-105°, etc., according to actual needs, as long as the angle D between the first connecting rod 131 and the second connecting rod 132 is in the range of 95°-105°.

[0044] By making the first connecting rod 131 and the second connecting rod 132 rotate relative to each other to the second position state, the angle D between the first connecting rod 131 and the second connecting rod 132 is in the range of 95°-105°, so that during the process of opening the door body 160 of the equipment to be installed relative to the main body 150 of the equipment to be installed, the door body 160 of the equipment to be installed will not interfere with the main body 150 of the equipment to be installed; if the equipment to be installed is a equipment to be installed embedded in a cabinet, during the process of opening the door body 160 of the equipment to be installed relative to the main body 150 of the equipment to be installed, the door body 160 of the equipment to be installed will not interfere with the cabinet.

[0045] In some embodiments, please refer to Figure 5 The hinge mechanism 100 includes a third rotation axis 141. The first connecting rod 131 and the second connecting rod 132 are rotationally connected via the third rotation axis 141.

[0046] It is understandable that the first connecting rod 131 has a fourth shaft hole (not shown) at one end close to the second connecting rod 132, and the second connecting rod 132 has a fifth shaft hole matched with the fourth shaft hole at one end close to the first connecting rod 131. The fourth shaft hole and the fifth shaft hole are sleeved on the third rotating shaft 141. The first link 131 and the second link 132 are rotatably connected via the third rotating shaft 141, so that during the process of relative rotation of the first link 131 and the second link 132 from the first position state to the second position state, the angle D between the first link 131 and the second link 132 gradually increases, and when the first link 131 and the second link 132 are relatively rotated to the second position state, the angle D between the first link 131 and the second link 132 reaches the maximum; at the same time, during the process of relative rotation of the first link 131 and the second link 132 from the second position state to the first position state, the angle D between the first link 131 and the second link 132 gradually decreases, and when the first link 131 and the second link 132 are relatively rotated to the first position state, the angle D between the first link 131 and the second link 132 is the smallest.

[0047] In some embodiments, please refer to Figure 6 , Figure 6A schematic diagram of the exploded structure of an embodiment of the hinge mechanism provided in the present application. The hinge seat 110 includes a first mounting portion 111 and a second mounting portion 112. The second mounting portion 112 is connected to one side of the first mounting portion 111. Specifically, the second mounting portion 112 is used to connect to the side of the first mounting portion 111 facing the device body 150 to be installed or the device door body 160 to be installed, so as to set the hinge seat 110 on one of the device body 150 to be installed and the device door body 160 to be installed. It can be understood that when the hinge seat 110 is used to be set on the body 150 of the device to be installed, and the self-locking member 120 is used to be set on the door body 160 of the device to be installed, the second mounting portion 112 of the hinge seat 110 is used to connect to the side of the first mounting portion 111 facing the body 150 of the device to be installed; when the hinge seat 110 is used to be set on the door body 160 of the device to be installed, and the self-locking member 120 is used to be set on the body 150 of the device to be installed, the second mounting portion 112 of the hinge seat 110 is used to connect to the side of the first mounting portion 111 facing the door body 160 of the device to be installed. The embodiment of the present application takes the hinge seat 110 used to be set on the body 150 of the device to be installed, and the self-locking member 120 used to be set on the door body 160 of the device to be installed as an example for explanation, and the second mounting portion 112 is used to connect to the side of the first mounting portion 111 facing the body 150 of the device to be installed, so as to set the hinge seat 110 on the body 150 of the device to be installed.

[0048] The first mounting portion 111 and the second mounting portion 112 are fixedly connected or integrally formed, wherein the fixed connection method may be riveting, bonding, bolting, magnetic adsorption connection or snap connection, but is not limited thereto; the integral forming method may be injection molding or stamping molding, but is not limited thereto. There is an angle between the first mounting portion 111 and the second mounting portion 112, and the angle between the first mounting portion 111 and the second mounting portion 112 may be a right angle, or close to a right angle. The hinge seat 110 is disposed on the device body 150 to be installed through the second mounting portion 112.

[0049] In some embodiments, the first mounting portion 111 includes a first side 1111 and a second side 1112 that are arranged opposite to each other. When the hinge seat 110 is arranged on the device body 150 to be installed, the first side 1111 is the side of the first mounting portion 111 close to the device body 150 to be installed and connected to the device door 160 to be installed, and the second side 1112 is the side of the first mounting portion 111 away from the device body 150 to be installed and connected to the device door 160 to be installed. The first mounting portion 111 has a first shaft hole 111a, and the first shaft hole 111a is close to the first side 1111 and the second mounting portion 112. The first connecting rod 131 has a second shaft hole 131a that matches the first shaft hole 111a, and the first shaft hole 111a and the second shaft hole 131a are used to match with the first rotating shaft 142 so that the first connecting rod 131 is rotatably arranged on the hinge seat 110.

[0050] Please continue reading Figure 2 and Figure 5 When the first connecting rod 131 and the second connecting rod 132 rotate relative to each other to the first position state, the first connecting rod 131 tilts from the first rotating axis 142 toward the second side 1112; during the process of the first connecting rod 131 and the second connecting rod 132 rotating relative to each other from the first position state to the second position state, the first connecting rod 131 rotates around the first rotating axis 142 in a direction deviating from the second side 1112.

[0051] In some embodiments, please continue to refer to 5 and Figure 6 The first mounting portion 111 includes a locking portion 1113. The locking portion 1113 is located at the second side 1112. The locking portion 1113 is used to engage with the self-locking member 120 to lock the door 160 of the device to be installed when the door 160 of the device to be installed is in a closed state relative to the body 150 of the device to be installed.

[0052] The clamping portion 1113 is formed with a clamping block 1113a and a first clamping groove 1113b which are arranged adjacent to each other. The opening of the first clamping groove 1113b faces away from the first side 1111, and the clamping block 1113a protrudes in a direction away from the first side 1111. The first clamping groove 1113b and the clamping block 1113a are used to engage with the self-locking member 120 to lock the door body 160 of the device to be installed. The inner wall of the first clamping groove 1113b and the surface of the clamping block 1113a are smoothly arranged, thereby reducing the friction between the first clamping groove 1113b and the self-locking member 120 and between the clamping block 1113a and the self-locking member 120, so as to facilitate the cooperation and dissociation of the self-locking member 120 and the clamping portion 1113.

[0053] In some embodiments, please refer to Figure 7 , Figure 7 Schematic diagram of the structure of the self-locking member of the hinge mechanism provided in the present application. The self-locking member 120 includes a supporting portion 121, a transition portion 122 and a locking portion 123 connected in sequence. The locking portion 123 is formed with a second card slot 123a. The opening of the second card slot 123a faces the supporting portion 121. The second card slot 123a is used to buckle with the card block 1113a.

[0054] The support portion 121, transition portion 122 and locking portion 123 of the self-locking member 120 may be an integrally formed structure. The support portion 121 is used to support the door body 160 of the device to be installed and the hinge body 130; the transition portion 122 is used to connect the support portion 121 and the locking portion 123; the locking portion 123 is used to engage with the clamping portion 1113 of the hinge seat 110 to lock the door body 160 of the device to be installed when the door body 160 of the device to be installed is in a closed state relative to the device body 150. When the door body 160 of the device to be installed is in a closed state relative to the device body 150, the clamping block 1113a of the clamping portion 1113 of the hinge seat 110 is clamped in the second clamping groove 123a of the locking portion 123, so that the door body 160 of the device to be installed is locked to the device body 150, so that the door body 160 of the device to be installed will not open automatically when it is in a closed state relative to the device body 150.

[0055] In some embodiments, the locking portion 123 includes a bending section 1231 and a locking section 1232. The bending section 1231 and the locking section 1232 form a second slot 123a. The notch of the second slot 123a is located between the bending section 1231 and the locking section 1232. The bending section 1231 includes a first section 1231a and a second section 1231b. The first section 1231a is connected to the transition section 122 and extends in a direction away from the transition section 122. The second section 1231b is connected to one end of the first section 1231a away from the transition section 122, and the second section 1231b is an arc section protruding in a direction away from the support portion 121. The locking section 1232 is connected to one end of the second section 1231b away from the first section 1231a, and is inclined in a direction toward the transition section 122. The locking section 1232 is used to be clamped in the first slot 1113b. When the door body 160 of the device to be installed is in a closed state relative to the main body 150 of the device to be installed, the locking section 1232 of the locking portion 123 of the self-locking member 120 is clamped in the first clamping groove 1113b of the clamping portion 1113 of the hinge seat 110, so that the door body 160 of the device to be installed is locked to the main body 150 of the device to be installed, so that the door body 160 of the device to be installed will not open automatically when it is in a closed state relative to the main body 150 of the device to be installed.

[0056] By forming a first slot 1113b and a block 1113a in the locking portion 1113 of the hinge seat 110, and forming a second slot 123a and a locking section 1232 in the locking portion 123 of the self-locking component 120, when the door body 160 of the device to be installed is in a closed state relative to the main body 150 of the device to be installed, that is, when the first connecting rod 131 and the second connecting rod 132 are relatively rotated to the first position state, the locking section 1232 is engaged with the first slot 1113b, and the second slot 123a is engaged with the block 1113a, so that the door body 160 of the device to be installed is locked to the main body 150 of the device to be installed. At the same time, the connection between the first connecting rod 131 and the second connecting rod 132 is spaced apart from the locking section 1232, so that the hinge body 130 will not interfere with the self-locking component 120. When the door body 160 of the device to be installed needs to be opened relative to the main body 150 of the device to be installed, the door body 160 of the device to be installed is pulled away from the main body 150 of the device to be installed, so that the second card slot 123a can be disengaged from the card block 1113a, and the locking section 1232 can be disengaged from the first card slot 1113b, thereby disengaging the self-locking member 120 from the hinge seat 110.

[0057] In some embodiments, the support portion 121 is provided with a fixing column 1211. The fixing column 1211 has a through hole 1211a. The self-locking member 120 is used to cooperate with the through hole 1211a through a fixing member to be set on the other of the device body 150 to be installed and the device door 160 to be installed.

[0058] It should be noted that when the hinge seat 110 is used to be set on the main body 150 of the equipment to be installed, and the self-locking part 120 is used to be set on the door body 160 of the equipment to be installed, the self-locking part 120 is used to cooperate with the through hole 1211a through a fixing component to be set on the door body 160 of the equipment to be installed; when the hinge seat 110 is used to be set on the door body 160 of the equipment to be installed, and the self-locking part 120 is used to be set on the main body 150 of the equipment to be installed, the self-locking part 120 is used to cooperate with the through hole 1211a through a fixing component to be set on the main body 150 of the equipment to be installed. The embodiment of the present application takes the self-locking part 120 being used to cooperate with the through hole 1211a through a fixing component to be set on the door body 160 of the equipment to be installed as an example.

[0059] The fixing column 1211 is fixedly connected or integrally formed with the support portion 121. It is understandable that when the fixing column 1211 is integrally formed with the support portion 121, it means that the fixing column 1211 and the support portion 121 are a whole; when the fixing column 1211 is fixedly connected to the support portion 121, it means that the fixing column 1211 and the support portion 121 are two separate components. The fixing component can be inserted into the through hole 1211a and the door body 160 of the device to be installed from the side of the self-locking member 120 away from the door body 160 of the device to be installed, so that the self-locking member 120 is fixed to the door body 160 of the device to be installed. In some embodiments, the fixing component can be a bolt, a screw, a stud or a rivet, but is not limited thereto.

[0060] A fixing column 1211 is formed on the side of the support portion 121 facing the door body 160 of the device to be installed, and the fixing column 1211 has a through hole 1211a. The self-locking component 120 cooperates with the through hole 1211a through a fixing component to be arranged on the door body 160 of the device to be installed, so that when the self-locking component 120 is fixed to the door body 160 of the device to be installed, the fixing column 1211 is located between the self-locking component 120 and the door body 160 of the device to be installed, and there is a gap between the self-locking component 120 and the door body 160 of the device to be installed, so that the hinge body 130 can rotate between the first position and the second position without interfering with the self-locking component 120 and the door body 160 of the device to be installed.

[0061] In some embodiments, please refer to Figure 6 The second connecting rod 132 has an escape opening 132a. The escape opening 132a is used to escape the fixed column 1211 when the door body 160 of the device to be installed is closed relative to the body 150 of the device to be installed. The escape opening 132a can play an evasive role for the fixed column 1211. When the door body 160 of the device to be installed is in a closed state relative to the body 150 of the device to be installed, that is, when the first connecting rod 131 and the second connecting rod 132 are relatively rotated to the first position state, the fixed column 1211 is accommodated in the escape opening 132a.

[0062] By forming an avoidance opening 132a in the second connecting rod 132, when the first connecting rod 131 and the second connecting rod 132 rotate relative to each other to the first position, the fixed column 1211 can be received in the avoidance opening 132a, thereby preventing the fixed column 1211 from blocking the relative rotation of the first connecting rod 131 and the second connecting rod 132, thereby allowing the door body 160 of the equipment to be installed to be successfully closed relative to the main body 150 of the equipment to be installed.

[0063] In some embodiments, the support portion 121 is provided with a second rotation shaft 1212. The second rotation shaft 1212 is located on a side of the fixed column 1211 away from the locking portion 123. The second rotation shaft 1212 is fixedly connected or integrally formed with the support portion 121. It can be understood that when the second rotation shaft 1212 is integrally formed with the support portion 121, it means that the second rotation shaft 1212 and the support portion 121 are a whole; when the second rotation shaft 1212 is fixedly connected to the support portion 121, it means that the second rotation shaft 1212 and the support portion 121 are two separate components.

[0064] The second connecting rod 132 has a third shaft hole 132b matched with the second rotating shaft 1212. The third shaft hole 132b is sleeved on the second rotating shaft 1212. The second connecting rod 132 can be rotatably disposed on the second rotating shaft 1212 through the third shaft hole 132b.

[0065] In some embodiments, the second rotating shaft 1212 is provided with a sleeve (not shown). The third shaft hole 132b of the second connecting rod 132 is sleeved in the sleeve. The second rotating shaft 1212 and the sleeve can rotate relative to each other to realize the pivoting function of the hinge body 130, and the second connecting rod 132 can be relatively fixed to the sleeve; or the second connecting rod 132 is rotatably arranged in the sleeve through the third shaft hole 132b to realize the pivoting function of the hinge body 130, and the sleeve can be relatively fixed to the second rotating shaft 1212. The provision of the sleeve can prevent the second rotating shaft 1212 from directly contacting the second connecting rod 132, reduce the wear of the second rotating shaft 1212 during the rotation of the hinge body 130, and thus ensure the service life of the second rotating shaft 1212 and the hinge body 130.

[0066] In the embodiment of the present application, the first connecting rod 131 is rotatably disposed on the hinge seat 110 via the first rotating shaft 142, the first connecting rod 131 and the second connecting rod 132 are rotatably connected via the third rotating shaft 141, and the second connecting rod 132 is rotatably disposed on the self-locking member 120 via the second rotating shaft 1212. In the process of opening or closing the door body 160 of the device to be installed relative to the body 150 of the device to be installed, the first connecting rod 131 and the second connecting rod 132 can relatively rotate to the first position state and the second position state via the third rotating shaft 141, the first rotating shaft 142 and the second rotating shaft 1212.
