[0037] The present invention provides a hinge mechanism 1 .

[0038] In the embodiment of the present invention, Figures 4 to 10As shown, the hinge mechanism 1 includes a mounting frame 10, a top shaft assembly 20 and a rotating assembly 30; the mounting frame 10 is used to be installed on the cabinet body 2, and the mounting frame 10 forms a mounting cavity 11; the top shaft assembly 20 is arranged in the mounting cavity 11, and the top shaft assembly 20 includes a top shaft 21 and an elastic member 22, one end of the elastic member 22 is connected to the cavity wall of the mounting cavity 11, and the other end is connected to the top shaft 21; the rotating assembly 30 is arranged in the mounting cavity 11, and the rotating assembly 30 includes a rotating shaft 31 and a cam 32, the rotating shaft 31 can be movably connected to the mounting frame 10, and is arranged on one side of the top shaft 21, and the cam 32 is sleeved on the rotating shaft; the rotation of the rotating shaft 31 drives the cam 32 to rotate and resist the top shaft 21, so as to compress the elastic member 22 so that it reacts to fix the cam 32 and the rotating shaft 31.

[0039] The mounting frame 10 is used to be installed on the cabinet 2. The shape of the mounting frame 10 can be a cube, a rectangular parallelepiped, a cylinder, etc. A mounting cavity 11 is formed in the mounting frame 10. The top shaft assembly 20 and the rotating assembly 30 are arranged in the mounting cavity 11. The mounting frame 10 has the function of fixing the position of the top shaft assembly 20 and the rotating assembly 30, and is used to support and maintain the position of the top shaft assembly 20 and the rotating assembly 30, maintaining the stability and safety of the top shaft assembly 20 and the rotating assembly 30 in the working state. The mounting frame 10 is installed at different positions in the cabinet 2, that is, the top shaft assembly 20 and the rotating assembly 30 are installed at different positions in the cabinet 2.

[0040] Further, if Figure 8 As shown, the top shaft assembly 20 includes a top shaft 21 and an elastic member 22. The elastic member 22 can be a spring, an elastic diaphragm, etc. In one embodiment of the present invention, the elastic member 22 is a coil spring. The top shaft 21 is arranged in the installation cavity 11. One end of the elastic member 22 is connected to the cavity wall of the installation cavity 11, and the other end is connected to the top shaft 21. It can be understood that the end of the elastic member 22 is against the side surface of the top shaft 21. When pressure is applied to the top shaft 21 in the direction of the elastic member 22, the elastic member 22 is compressed, and the top shaft 21 is subjected to the reverse elastic force of the elastic member 22, so that the top shaft 21 is subjected to a reaction force opposite to the applied pressure.

[0041] Preferably, the top shaft 21 is arranged along an extension direction perpendicular to the ground, and the extension direction of the elastic member 22 is perpendicular to the extension direction of the top shaft 21. With this arrangement, the two ends of the elastic member 22 can be respectively attached to the cavity wall of the installation cavity 11 and the side surface of the top shaft 21, thereby ensuring that the pressure of the top shaft 21 is fully applied to the elastic member 22, and ensuring the contact position of the top shaft 21 and the elastic member 22, avoiding the positional offset of the elastic member 22 and the top shaft 21 in the mounting frame 10 due to the compression of the elastic member 22, thereby improving the working stability of the top shaft assembly 20.

[0042] Further, if Figure 7As shown, the rotating assembly 30 includes a rotating shaft 31 and a cam 32. The rotating shaft 31 is movably connected to the mounting bracket 10. In one embodiment of the present invention, the rotating shaft 31 is arranged along an extension direction perpendicular to the ground. Such an arrangement, on the one hand, ensures that the rotation center lines of the rotating shaft 31 and the cam 32 are perpendicular to the ground, and on the other hand, ensures that the contact surface 321 is in contact with the top shaft 21, thereby improving the effectiveness and stability of the rotating shaft 31 rotating and contacting the top shaft 21. The hinge mechanism 1 also includes a connecting rod 40, one end of which is connected to the rotating shaft 31 and rotates around the rotating shaft 31 as the center line, and the other end is movably connected to the cabinet door 3 and can rotate with the cabinet door 3. The position of the rotating shaft 31 and the length of the connecting rod 40 are fixed, so that the rotation trajectory of the cabinet door 3 is fixed by the rotating shaft 31.

[0043] Furthermore, the cam 32 is sleeved on the rotating shaft 31, and the rotating shaft 31 is arranged on the side of the top shaft 21 away from the elastic member 22. The cam 32 has an arc surface. In one embodiment of the present invention, the curvature of the arc surface is the same as the angle between the cabinet door 3 fully opened and closed on the cabinet body 2, and the radius of the arc surface is greater than the distance between the top shaft 21 and the rotating shaft 31. Therefore, when the cabinet door 3 is rotated, the cabinet door 3 rotates to drive the connecting rod 40 and the rotating shaft 31 to rotate, and then drives the cam 32 to rotate. The outer peripheral surface of the cam 32 located on the arc surface abuts the top shaft 21. Since the radius of the arc surface is greater than the distance between the top shaft 21 and the rotating shaft 31, the top shaft 21 is located on the mounting bracket 1. 0 is movably arranged, and the cam 32 applies pressure to the top shaft 21 in a direction away from the rotating shaft 31, causing the top shaft 21 to move in a direction away from the rotating shaft 31, that is, toward the elastic member 22, thereby compressing the elastic member 22. The elastic member 22 compresses and generates a reaction force on the top shaft 21 and the cam 32. Since the cam 32 is coaxially arranged with the rotating shaft 31, the elastic member 22 generates a reaction force on the rotating shaft 31. The reaction force is then transmitted to the connecting rod 40 and the cabinet door 3, so that the elastic member 22, the top shaft 21, the cam 32, the rotating shaft 31, the connecting rod 40 and the cabinet door 3 are all in a relatively static state, achieving the effect of stabilizing the cabinet door 3 at any angle. It can be understood that when an elastic force greater than that of the elastic member 22 is applied to the cabinet door 3, the cabinet door 3 can rotate. When no force is applied to the cabinet door 3, the cabinet door 3 is in a stable hovering state.

[0044] Furthermore, the cam 32 and the rotating shaft 31 can be an integrally formed structure. The integrally formed cam 32 and the rotating shaft 31 can improve the overall strength of the rotating component 30, improve the rotation accuracy of the rotating component 30, ensure that the rotation angle of the rotating component 30 is the same as the rotation angle of the cabinet door 3, and improve production efficiency.

[0045] Further, if Figure 5As shown, the rotating shaft 31 is a cylinder, and the central cross-sectional shape of the rotating shaft 31 can be an irregular shape such as a square or a rectangle. In one embodiment of the present invention, the central cross-sectional shape of the rotating shaft 31 is a notched circle. Similarly, the connecting shaft of the connecting rod 40 is inserted into the rotating shaft 31, and the cross-sectional shape of the connecting shaft is the same as the central cross-sectional shape of the rotating shaft 31, so that the rotating shaft 31 can rotate synchronously with the connecting rod.

[0046] The technical solution of the present invention is to install the hinge mechanism 1 between the cabinet body 2 and the cabinet door 3, and the hinge mechanism 1 is installed in the cabinet body 2 through the mounting frame 10. The top shaft assembly 20 and the rotating assembly 30 in the mounting frame 10 cooperate with each other, and one end of the connecting rod 40 is connected to the cabinet door 3, and the other end is connected to the rotating assembly 30, thereby connecting the mounting frame 10 and the cabinet door 3. The cabinet door 3 rotates to drive the connecting rod 40 and the rotating assembly 30 to rotate. The rotating assembly 30 includes a rotating shaft 31 and a cam 32. The rotation of the rotating shaft 31 drives the cam 32 to rotate, and the cam 32 can resist the top shaft assembly 20; when When the cabinet door 3 is between the open and closed states, the protruding part of the cam 32 abuts against the top shaft assembly 20 and compresses the elastic member 22, so that the elastic member 22 applies a reaction force to the rotating assembly 30, limiting the rotation of the rotating assembly 30, and thereby limiting the rotation of the connecting rod 40 and the cabinet door 3, thereby suspending the cabinet door 3 at any position and keeping it fixed; the mounting frame 10 is installed on the side wall of the cabinet body 2, and the connecting rod 40 is connected to the middle part of the cabinet door 3, so that the cabinet door 3 is offset toward one side of the cabinet body 2 when it is opened, thereby achieving avoidance of the user when the cabinet door 3 is opened.

[0047] In one embodiment of the present invention, Figure 7 As shown, the surface where the cam 32 contacts the top shaft 21 is defined as a contact surface 321 . The contact surface 321 includes a circular curved surface 321 a and inclined surfaces 321 b on both sides of the circular curved surface 321 a . The curvature of the inclined surface 321 b is greater than that of the circular curved surface 321 a .

[0048] The curvature of the circular curved surface 321a corresponds to the rotation angle of the cabinet door 3 between fully open and fully closed, and the curvature of the inclined surface 321b corresponds to the rotation angle of the cabinet door 3 when opening and closing. The curvature of the inclined surface 321b is greater than the curvature of the circular curved surface 321a, so the radius of the cam 32 decreases from the connection between the circular curved surface 321a and the inclined surface 321b to the side of the inclined surface 321b away from the circular curved surface 321a. It can be understood that when the circular curved surface 321a of the cam 32 rotates toward the top shaft 21, the diameter of the circular curved surface 321a is greater than the distance between the top shaft 21 and the rotating shaft 31, and the cam 32 squeezes the top shaft 21 and the elastic member 22. The elastic member 22 generates a reaction force, which makes the elastic member 22, the top shaft 21, the cam 32, the rotating shaft 31, the connecting rod 40 and the cabinet door 3 all relatively stationary, thereby achieving the effect of stabilizing the cabinet door 3 at any angle. When the cam 32 rotates until the inclined surface 321b faces the top shaft 21, the diameter of the inclined surface 321b is smaller than the distance between the top shaft 21 and the rotating shaft 31. The cam 32 is unable to squeeze the top shaft 21 and the elastic member 22, and the cam 32 and the rotating shaft 31 are not subjected to the elastic force of the elastic member 22. Furthermore, when the cabinet door 3 is about to be fully opened or fully closed, the surface of the top shaft 21 that abuts the cam 32 shifts from the circumferential curved surface 321a to the inclined surface 321b. Due to the reduced diameter of the inclined surface 321b, the abutting force of the cam 32 decreases, and the restoring force of the elastic member 22 increases, thereby forcing the top shaft 21 to move toward the rotating shaft 31, thereby causing the cabinet door 3 to move toward the fully opened or fully closed state. This facilitates the advancement of the cabinet door 3 when it is nearing the fully opened or fully closed state, ensuring a tight fit between the cabinet door 3 and the cabinet body 2 in both the closed and open states.

[0049] In one embodiment of the present invention, Figure 8 、 Figure 10 As shown, the top shaft assembly 20 also includes a mounting seat 23, which includes a mounting portion 231 and a connecting portion 233 connected to each other. The connecting portion 233 can be movably connected to the cavity wall of the mounting cavity 11, and the top shaft 21 is inserted into the mounting portion 231. The elastic member 22 is sleeved on the connecting portion 233 and abuts against the surface of the mounting portion 231. The mounting seat 23, the top shaft 21 and the elastic member 22 move synchronously.

[0050] The top shaft 21 is inserted into the mounting portion 231. In this embodiment, the mounting portion 231 is provided with a mounting groove, which is formed with upper and lower opposite groove walls. The upper and lower groove walls are each provided with a through hole. The two ends of the top shaft 21 are respectively inserted into the through holes, so that the top shaft 21 is fixed in the mounting portion 231. The side of the mounting portion 231 facing away from the top shaft 21 is connected to the connecting portion 233. The shape of the connecting portion 233 can be cylindrical, rectangular, cube, etc. In this embodiment, the shape of the connecting portion 233 is cylindrical. Since the elastic member 22 is a coil spring, the cylindrical connecting portion 233 matches the shape of the coil spring, which facilitates elastic sleeve installation outside the connecting portion 233. With this arrangement, the top shaft 21 and the elastic member 22 are both connected to the mounting seat 23, and the three form a whole, which ensures the tightness of the connection between the top shaft 21 and the elastic member 22, so that the mounting seat 23, the top shaft 21 and the elastic member 22 move synchronously, ensuring the movement effect of the top shaft assembly 20, that is, the cam 32 supports the top shaft 21, and the top shaft 21 and the mounting seat 23 move synchronously, thereby compressing the elastic member 22, realizing the synchronous movement of the three, and improving the stability and working efficiency of the top shaft assembly 20.

[0051] In one embodiment of the present invention, Figure 6 、 Figure 8 、 Figure 9 As shown, movable holes 141 are formed on two opposite sides of the mounting frame 10 . The movable holes 141 extend along the extending direction of the elastic member 22 . Both ends of the top shaft 21 can be movably inserted into the movable holes 141 .

[0052] In one embodiment of the present invention, the movable hole 141 can be a strip-shaped hole extending along the extension direction of the elastic member 22, that is, along the direction of the top shaft 21 approaching or moving away from the rotating shaft 31. The movable holes 141 on opposite sides of the mounting frame 10 are aligned. Furthermore, the width of the strip-shaped hole is the same as the diameter of the top shaft 21. The ends of the top shaft 21 are movably inserted into the movable hole 141, that is, the ends of the top shaft 21 can only move along the extension direction of the strip-shaped hole. The provision of the movable hole 141, on the one hand, limits the movement trajectory of the top shaft 21, ensuring that the top shaft 21 moves toward the elastic member 22 after being pressed by the cam 32 and moves toward the rotating shaft 31 after being released from the pressure, thereby ensuring the effectiveness of the rotating shaft 31. On the other hand, it limits the compression distance of the elastic member 22. By adjusting the size of the movable hole 141, the movement distance of the top shaft 21 can be changed, thereby changing the range of motion of the top shaft 21, preventing excessive compression and protecting the stability of the hinge mechanism 1.

[0053] In one embodiment of the present invention, Figures 6 to 10 As shown, the hinge mechanism 1 further includes a buffer member 50 , which is disposed in the mounting cavity 11 . One end of the buffer member 50 is connected to the cavity wall of the mounting cavity 11 , and the other end abuts against the surface of the mounting portion 231 facing the rotating assembly 30 .

[0054] When the cam 32 contacts the top shaft 21, the cam 32 and the top shaft 21 move from the circumferential surface 321a to the inclined surface 321b. As the diameter of the inclined surface 321b decreases, the elastic member 22 recovers quickly, which will cause the door 3 to close faster. The buffer member 50 is arranged in the accommodating cavity, and one end is abutted against the mounting seat 23, so as to avoid the elastic member 22 from quickly recovering and rebounding the mounting seat 23 due to excessive changes in the inclined surface 321b of the cam 32. The reaction force of the oil cylinder is used to limit the rapid rebound of the mounting seat 23, so that the mounting seat 23 and the top shaft 21 move toward the rotating shaft 31 smoothly. When the top shaft 21 is located on the inclined surface 321b of the cam 32, the rebound force is reduced, so that the advancement process of the door 3 is smooth when it is close to being fully opened or fully closed, thereby improving safety.

[0055] In one embodiment of the present invention, Figures 8 to 10 As shown, the hinge mechanism 1 also includes an adjusting component 60, which is arranged in the installation cavity 11. The adjusting component 60 includes a fixed plate 61, a movable plate 62 and a connecting member 63. The fixed plate 61 is fixedly connected to the cavity wall of the installation cavity 11, and the connecting member 63 can be movably passed through the fixed plate 61. The movable plate 62 is sleeved on the connecting member 63 and is supported on the end of the elastic member 22 away from the installation portion 231. The connecting portion 233 is passed through the movable plate 62.

[0056] The fixed plate 61 is fixed to the mounting frame 10, and the connecting member 63 is provided through both the fixed plate 61 and the movable plate 62. The connecting member 63 can be a bolt, a screw, etc. In one embodiment of the present invention, the connecting member 63 is a bolt. The movable plate 62 is located on the side of the fixed plate 61 close to the mounting seat 23. The position of the movable plate 62 on the bolt 63 is fixed. By rotating the bolt 63, the position of the movable plate 62 relative to the fixed plate 61 can be changed to move closer to or away from the fixed plate 61. Since the connecting portion 233 of the mounting seat 23 is provided through the movable plate 62, the elastic member 22 is sleeved on the movable plate 62, that is, one end of the elastic member 22 abuts the mounting portion 231 of the mounting seat 23, and the other end abuts the movable plate 62. When the mounting seat 23 is not squeezed, it is in a fixed state, the position of the mounting seat 23 is fixed, and the position of the movable plate 62 is changed by adjusting the bolt 63. When the movable plate 62 is away from the fixed plate 61, the compression elastic member 22 abuts one end of the movable plate 62. When the movable plate 62 is close to the fixed plate 61, the compression elastic member 22 abuts one end of the movable plate 62. By adjusting the movable plate 62, the compression elastic member 22 is adjusted. Because the forces at both ends of the elastic member 22 are synchronous and opposite, the elastic force of the other end of the elastic member 22 is changed, thereby changing the elastic force of the elastic member 22 on the mounting seat 23 and the top shaft 21. At this time, the top shaft 21 is not squeezed by the rotating shaft 31. By changing the compression amount of the elastic member 22, the pre-pressure of the top shaft 21 toward one side of the rotating shaft 31 can be adjusted, the reaction force after the rotating shaft 31 and the top shaft 21 are pressed can be adjusted, and the hovering force on the cabinet door 3 can be adjusted to achieve the hovering force adjustment under different environmental conditions.

[0057] In one embodiment of the present invention, Figures 4 to 10 As shown, the mounting frame 10 includes a base 12, an inner shell 13 and an outer shell 14. The base 12 and the inner shell 13 are detachably connected. The base 12 is used to be connected to the cabinet 2. The outer shell 14 is sleeved on the outer surface of the inner shell 13. The outer shell 14 and the base 12 enclose a mounting cavity 11.

[0058] The base 12 is detachably connected to the inner shell 13, and the detachable connection method can be a snap connection 131 connection, a threaded connection, etc. The outer shell 14 is sleeved on the outer surface of the inner shell 13, that is, the outer shell 14 and the inner shell 13 can be regarded as an integrated structure. The inner shell 13 can be used to be detachably connected to the base 12 to achieve modular installation of the base 12 and the inner shell 13. The top shaft assembly 20 and the rotating assembly 30 are both installed in the outer shell 14. During installation, it is only necessary to first install the base 12 on the cabinet 2, and then install the inner shell 13 and the outer shell 14 on the base 12 to complete the installation of the mounting frame 10. Furthermore, the connection method between the base 12 and the cabinet 2 can be a threaded connection, bonding, welding, etc. Such a setting can achieve modular installation of the mounting frame 10, facilitate the installation of the mounting frame 10, achieve quick installation and disassembly, and improve the installation efficiency of the mounting frame 10.

[0059] In one embodiment of the present invention, Figures 8 to 10 As shown, the mounting bracket 10 further includes a snap-fastener 15 , one end of which is fixed to the inner shell 13 , and the other end of which is movably snap-fastened to the base 12 .

[0060] The snap-fastener 15 comprises a snap and a torsion spring. It will be appreciated that the torsion spring's rotational center is fixed to the inner housing 13, and one end of the snap-fastener 15 is connected to the torsion spring, allowing the other end of the snap-fastener 15 to rotate along the end connected to the torsion spring. This allows the snap-fastener 15 to be compressed by the elastic force of the torsion spring. When the base 12 and the inner housing 13 are assembled, the snap-fastener 15 is pulled away from the end of the torsion spring to clamp it onto the base 12. The snap-fastener 15 is then released to clamp it onto the base 12, completing the connection between the base 12 and the inner housing 13.

[0061] Furthermore, when the base 12 is combined with the inner shell 13, a snap 131 is provided on the inner shell 13 relative to the other side where the spring fastener 15 is provided, and the snap 131 is arranged in the direction of one side of the spring fastener 15. When the base 12 and the inner shell 13 are installed, the snap 131 is first engaged with the edge of the side of the base 12 away from the connection with the spring fastener 15, and then the spring fastener 15 is clamped on the base 12, so that the inner shell 13 is clamped and fixed to the opposite sides of the base 12 respectively, completing the combination of the base 12 and the inner shell 13, and ensuring the stability of the combination of the base 12 and the inner shell 13.

[0062] In one embodiment of the present invention, Figures 8 to 10 As shown, the mounting bracket 10 further includes a first adjusting member 16 , which is disposed through the base 12 . The first adjusting member 16 is rotated to allow the mounting bracket 10 to reciprocate in the height direction of the cabinet 2 .

[0063] And / or, the mounting bracket 10 further includes a second adjusting member 17 , which is disposed through the outer shell 14 and the inner shell 13 , and the second adjusting member 17 is rotated to allow the mounting bracket 10 to reciprocate in the width direction of the cabinet 2 .

[0064] The base 12 includes a first bottom plate 121 and a second bottom plate 123. The cabinet body 2 is connected to the first bottom plate 121, and the inner shell 13 is connected to the second bottom plate 123. The first bottom plate 121 and the second bottom plate 123 are connected by a first adjustment member 16. The second bottom plate 123 has a first adjustment hole. The first adjustment member 16 is inserted into the first bottom plate 121 and can move within the first adjustment hole. The first adjustment hole extends in the vertical direction. In this embodiment, the first adjustment hole is a bar-shaped hole, and the first adjustment member 16 is an eccentric rivet. When the first adjustment member 16 is rotated within the first adjustment hole, it can control the second bottom plate 123 to reciprocate in the vertical direction. Because the inner shell 13 is connected to the second bottom plate 123, and the outer shell 14 is also connected to the second bottom plate 123, the mounting bracket 10 can reciprocate in the vertical direction via the first adjustment member 16.

[0065] The inner shell 13 and the outer shell 14 are connected by a second adjustment member 17. The inner shell 13 has a second adjustment hole. The second adjustment member 17 is inserted through the outer shell 14 and is movable within the second adjustment hole. The second adjustment hole extends horizontally. In this embodiment, the second adjustment hole is a strip-shaped hole, and the second adjustment member 17 is an eccentric rivet. When the second adjustment member 17 rotates within the second adjustment hole, it can control the reciprocating horizontal movement of the inner shell 13, thereby allowing the mounting bracket 10 to reciprocate horizontally via the second adjustment member 17.

[0066] It can be understood that during the installation process, the first adjusting member 16 can be used to fine-tune the mounting frame 10 as a whole up and down, thereby fine-tuning the cabinet door 3 up and down, and adjusting the gap between the cabinet door 3 and the top of the cabinet body 2 to prevent the installation from causing the gap to be too large or the gap to be uneven, resulting in an unsightly appearance. The second adjusting member 17 can be used to fine-tune the mounting frame 10 as a whole left and right, thereby fine-tuning the cabinet door 3 left and right, thereby achieving fine-tuning of the mounting base 23 as a whole along the depth direction of the cabinet body 2, so that after the cabinet door 3 is installed on the cabinet body 2, the surface is flat, preventing the cabinet door 3 from being uneven in the depth direction with the cabinet body 2 when closed, resulting in a reduction in aesthetics.

[0067] Furthermore, the number of first adjustment members 16 and second adjustment members 17 can be multiple, and similarly, the number of first adjustment holes and second adjustment holes can also be multiple, with one first adjustment member 16 correspondingly connected to one first adjustment hole, and one second adjustment member 17 correspondingly connected to one second adjustment hole. Furthermore, the multiple adjustment members are spaced apart to ensure integrated adjustment of the base 12 and inner shell 13, ensuring synchronized movement of each position.
