[0033] Such as Figures 1 - 5As shown, in this embodiment, a silent hinge includes a hinge assembly, a rotating shaft 3, a shaft sleeve 4, and a buffer pad 5. Among them, the hinge assembly includes a first connecting member 1 and a second connecting member 2. Both the first connecting member 1 and the second connecting member 2 are provided with through holes, and the rotating shaft 3 sequentially passes through the through holes of the first connecting member 1 and the second connecting member 2. The shaft sleeve 4 is sleeved on the rotating shaft 3, and the outer circumference of the shaft sleeve 4 can abut against the hole wall of the through hole. There are two buffer pads 5, and the two buffer pads 5 respectively cover the first connecting member 1 and the second connecting member 2. Specifically, the first connecting member 1 and the second connecting member 2 are used to connect structures that need to rotate, such as between the bed board and the bed frame, between the headboard and the bed body, etc., and the first connecting member 1 and the second connecting member 2 rotate relative to each other through the rotating shaft 3. Among them, the rotating shaft 3 is rotatably arranged in the through holes of the first connecting member 1 and the second connecting member 2. The shaft sleeve 4 is made of plastic material. The inner ring of the shaft sleeve 4 is connected to the outer peripheral surface of the rotating shaft 3, and the outer ring of the shaft sleeve 4 is connected to the hole wall of the through hole, that is, the shaft sleeve 4 is clamped between the rotating shaft 3 and the hole wall of the through hole along the circumferential direction of the rotating shaft 3. The shaft sleeve 4 is used to buffer the connection between the hinge assembly and the rotating shaft 3 and can reduce the noise during the movement of the hinge. At the same time, the end faces of both the first connecting member 1 and the second connecting member 2 are covered with buffer pads 5. The buffer pads 5 are made of rubber material. The buffer pads 5 can reduce the impact force during the rotation of the hinge assembly and further reduce the noise during the movement of the hinge, thereby improving the sleep comfort level.
[0034] Further, continuing to refer to Figures 1 - 5 , a buffer member 6 is provided on the outer circumference of the shaft sleeve 4, and the buffer member 6 abuts against the hole wall of the through hole. Specifically, the first connecting member 1 and the second connecting member 2 rotate relative to each other through the rotating shaft 3. The shaft sleeve 4 is clamped between the rotating shaft 3 and the hole wall of the through hole along the circumferential direction of the rotating shaft 3. The buffer member 6 provided on the outer circumference of the shaft sleeve 4 can abut against the hole wall of the through hole, that is, the buffer member 6 is clamped between the shaft sleeve 4 and the hole wall of the through hole, and is used to buffer the connection between the shaft sleeve 4 and the hinge assembly, thereby reducing the noise during the movement of the hinge and improving the sleep comfort level. Optionally, a buffer member 6 is provided on the inner circumference of the shaft sleeve 4, and the buffer member 6 abuts against the outer peripheral surface of the rotating shaft 3. There are multiple buffer members 6. The rotating shaft 3 sequentially passes through the through holes of the first connecting member 1 and the second connecting member 2. The shaft sleeve 4 is sleeved on the rotating shaft 3, and the buffer member 6 provided on the inner circumference of the shaft sleeve 4 can abut against the outer periphery of the rotating shaft 3, that is, the buffer member 6 is clamped between the shaft sleeve 4 and the rotating shaft 3, and is used to buffer the connection between the shaft sleeve 4 and the rotating shaft 3, thereby reducing the noise during the movement of the hinge.
[0035] Further, referring to Figure 3 , the buffer member 6 has a block structure, and multiple buffer members 6 are arranged in an array along the circumferential direction of the shaft sleeve 4. Specifically, there are multiple buffer members 6. There is a gap between the multiple buffer members 6 with a block structure arranged on the outer circumference or inner circumference of the shaft sleeve 4. This gap can reduce the impact force during rotation, thereby reducing the noise during the movement of the hinge.
[0036] Further, referring to Figure 4 , the buffer member 6 is in a ring structure, and a plurality of buffer members 6 are arranged at intervals along the axial direction of the bushing 4. Specifically, there is an interval between the plurality of buffer members 6 in a ring structure arranged on the outer periphery or inner periphery of the bushing 4, and this interval can reduce the impact force during rotation, thereby reducing the noise during the movement of the hinge.
[0037] Further, referring to Figure 5 , the buffer member 6 is in a strip structure, and a plurality of buffer members 6 are arranged at intervals along the circumferential direction of the bushing 4. The two ends of the buffer member 6 are respectively connected to the head and the tail of the bushing 4. Specifically, there is an interval between the plurality of buffer members 6 in a strip structure arranged on the outer periphery or inner periphery of the bushing 4, and this interval can reduce the impact force during rotation, thereby reducing the noise during the movement of the hinge.
[0038] Further, referring to Figure 2 , a plurality of bushings 4 are arranged at intervals along the length direction of the rotating shaft 3. Specifically, in this embodiment, the number of bushings 4 is four, which are divided into two groups in pairs, and the two groups of bushings 4 are symmetrically arranged. The rotating shaft 3 passes through the two groups of bushings 4 in sequence, that is, the four bushings 4 are all clamped between the rotating shaft 3 and the hole wall of the through hole along the circumferential direction of the rotating shaft 3, used for buffering the connection between the hinge assembly and the rotating shaft 3, and can further reduce the noise during the movement of the hinge. A limiting member 7 is provided at the head of the bushing 4, and the limiting member 7 is used to abut against the opening of the through hole. The limiting members 7 corresponding to each group of bushings 4 can abut against the two ends of the through hole, so that the two groups of bushings 4 can respectively abut against the through holes of the first connecting member 1 and the second connecting member 2 through the corresponding limiting members 7, so that relative displacement and loosening are not likely to occur between the first connecting member 1 and the second connecting member, and the connection is stable.
[0039] Further, referring to Figures 1 - 2 , the buffer pad 5 includes a buffer pad body 51 and a protrusion 52. The protrusion 52 is provided at the edge of the buffer pad body 51, and the buffer pad body 51 is attached to the end face of the hinge assembly, and the protrusion 52 abuts against the outer edge of the hinge assembly. Specifically, the protrusion 52 is in a U-shaped structure, and along the outer edge direction of the buffer pad body 51, the protrusion 52 is fixedly connected to one end of the buffer pad body 51 away from the through hole. The protrusions 52 of the two buffer pads 5 respectively wrap the outer edges of the first connecting member 1 and the second connecting member 2, and the corresponding two buffer pad bodies 51 are respectively attached to the end faces of the first connecting member 1 and the second connecting member 2, which can reduce the impact force during the rotation of the hinge assembly, further reduce the noise during the movement of the hinge, and thus improve the sleep comfort.
