[0029] Embodiment

[0030] First of all, in the implementation mode of the present application, the buffer 5 is a hydraulic damper. The hydraulic damper includes a piston rod and a piston. At this time, there is a distance between the bottom of the piston rod and the piston. This distance is the total length of the telescopic adjustment of the first slider 61 and the second slider 62, so as to adjust the size of the distance to achieve the time to trigger the movement of the piston. During the movement of the piston rod, the through hole on the piston allows the liquid to flow between the two sides of the cylinder block, thereby generating a damping effect, so that the closing speed of the door gradually slows down, achieving a soft and silent effect; among them, in the hydraulic system, the piston rod and the piston are generally fixedly connected, and their reset is generally achieved through the change of hydraulic pressure. However, in this implementation mode, the piston is fixedly connected with a spring, and the other end of the spring is fixedly connected with the inner wall of one end of the cylinder block. The piston rod can telescopically move relative to the piston. At this time, the piston can be fixed at a specified position and can also be reset by the elastic force of the spring. At the same time, a stop disk with a through hole is also provided at the end of the piston rod. Then, when the piston rod follows the opening or closing of the door body to stretch and contract, the piston can be stretched by the drive of the piston rod and reset under the pull of the spring, so that the buffering can be realized through the hydraulic oil, the friction between the tail of the piston rod or the piston and the inner wall of the cylinder block, and the stretching ability of the spring. Based on this, the distance between the piston rod and the piston can be adjusted by the piston rod.

[0031] Such as Figures 1 to 3As shown in the figure, a damping concealed hinge with adjustable buffer angle includes a cup seat 1, a rocker arm 2 and a base 3 which are installed in cooperation with each other. A connecting arm 4 is installed on the base 3. A buffer 5 for connecting with the rocker arm 2 is arranged inside the connecting arm 4. A chute 41 is arranged at the top of the connecting arm 4. An adjusting component 6 for connecting the rocker arm 2 and the buffer 5 is installed in the chute 41. The adjusting component 6 includes a first slider 61, a second slider 62 slidably connected with the first slider 61 and a pressing block 63 fixedly installed above the second slider 62. The first slider 61 is embedded and sleeved inside the second slider 62. A plurality of clamping grooves 611 are formed in the first slider 61. A plurality of clamping holes 621 are formed in the second slider 62. A clamping post 631 is arranged at one end of the pressing block 63. The clamping grooves 611, the clamping holes 621 and the clamping post 631 are arranged in the same straight line. The clamping post 631 passes through the clamping hole 621 and extends into or out of the clamping groove 611, so that the first slider 61 and the second slider 62 are limited and fixed or slide relatively.

[0032] Specifically, including but not limited to, the cup seat 1, the rocker arm 2 and the base 3 are common in the market and have been described in detail in the prior art. At the same time, it should be noted that in this embodiment, the buffer 5 and the adjusting component 6 are fixed to the connecting arm 4, that is, they cannot move integrally relative to the connecting arm 4. Compared with the direct fixed connection between the buffer 5 and the rocker arm 2 in the prior art, in this application, by arranging the adjusting component 6 between the buffer 5 and the rocker arm 2, the overall length of the adjusting component 6 can be adjusted to change the piston trigger time, so as to adjust the buffer angle of the door.

[0033] Specifically, including but not limited to, the chute 41 on the connecting arm 4 is a rectangular groove. The opening length of the rectangular groove is greater than the length of the second slider 62, which is convenient for providing the sliding distance of the second slider 62. At the same time, both ends of the second slider 62 are fixed to the side wall of the chute 41, and the two are clamped and fixed to ensure the structural stability.

[0034] Specifically, including but not limited to, the first slider 61 and the second slider 62 can be rectangular plates, the first slider 61 is embedded in the second slider 62, and the card slot 611, the card hole 621 and the card column 631 are all circular structures. The multiple card slots 611 are multiple adjustable gears. Then, when the second slider 62 moves toward the cup holder 1 along the length direction, it is adjusted to the high gear, and vice versa, it is adjusted to the resistance. Of course, the highest gear is when the end of the piston rod is in contact with the piston, and the lowest gear is when the end of the piston rod is farthest from the piston. The farthest distance can be adjusted according to actual application. Design, and the spacing between two adjacent slots, that is, the adjustment length of one gear, can also be set according to actual production; finally, in order to facilitate clear observation and sensing between the adjustments of multiple gears, the number of gears is engraved on the top of the connecting arm 4 along the length direction of the slide groove 41, which is convenient for direct observation during adjustment. At the same time, a plurality of convex strips can be set along the wall of the slide groove 41, and each convex strip corresponds to a slot 611. Correspondingly, a plurality of concave strips are provided on the inner wall surfaces on both sides of the second slider 62. Then, every time a gear is adjusted, a slight sense of jamming can be felt, thereby giving the adjuster a clear sense.

[0035] Specifically, including but not limited to, the pressing block 63 can be a common switch structure on the market, and can lift the other end by pressing one end, thereby driving the card column 631 to rise and fall, so that the card column 631 passes through the card hole 621, and when the card column 631 extends into the card slot 611, the second slider 62 cannot move relative to the first slider 61 and is fixed to each other. When the card column 631 extends out of the card slot 611, the second slider 62 can move relative to the first slider 61, and the overall length of the adjustment component 6 can be changed. The structure is simple, easy to produce, and can be widely promoted on the market.

[0036] Through the above scheme, the present application changes the extension length of the piston rod at the front end of the buffer 5, thereby changing the actual distance between the rocker arm 2 and the buffer 5, thereby adjusting the actual buffering angle of the buffer 5 triggered when the rocker arm 2 rotates, and can meet the needs of more customers or markets.

[0037] As an improved specific implementation, a boss 622 is provided above the second sliding block 62 , a receiving groove 623 is defined in the boss 622 , and the pressing block 63 is received in the receiving groove 623 .

[0038] Specifically, including but not limited to, the boss 622 is arranged along the outer wall of the pressing block 63, and there is a gap between the boss 622 and the pressing block 63 to prevent friction between the pressing block 63 and the boss 622, which may impede the pressing and resetting of the pressing block 63, extend the service life of the pressing block 63. The receiving groove 623 should be slightly larger than the pressing block 63 to facilitate the pressing block 63 to be received and fixed in the receiving groove 623. At the same time, the depth of the receiving groove 623 can be set according to actual needs to prevent the pressing block 63 from disengaging from the receiving groove 623. The side of the boss 622 can further limit the pressing block 63.

[0039] Through the above solution, the cooperation of the boss 622 and the receiving groove 623 can limit and place the pressing block 63, and can also provide the moving range at both ends of the pressing block 63.

[0040] As a specific implementation of the improvement, a first fixing groove 632 is opened at the bottom of one end of the pressing block 63. The first fixing groove 632 corresponds to the card slot 611. The top end of the card post 631 is embedded in the first fixing groove 632, and the bottom end of the card post 631 is embedded in the card slot 611.

[0041] Specifically, including but not limited to, the first fixing groove 632 is opened at the end of the pressing block 63 away from the buffer 5. The first fixing groove 632 is set as a circular groove corresponding to the card post 631. At this time, the top end of the card post 631 is embedded and fixed in the first fixing groove 632. The bottom end of the card post 631 can pass through the card hole 621 of the second slider 62 and then extend into the card slot 611. In this embodiment, the card post 631 and the pressing block 63 are set as a split structure, and the card post 631 can be fixed by screws or other means. Of course, the card post 631 and the pressing block 63 can also be set as an integral structure, which is convenient for the installation and production of the pressing block 63. It should be noted that the front end of the pressing block 63 can abut against the inner wall of the second slider 62 after the rising distance of the card post 631 extends, further limiting the pressing block 63.

[0042] Through the above solution, the first fixing groove 632 can limit and fix the card post 631, so that when the front end of the pressing block 63 rises or falls, it can drive the card post 631, realizing the linkage of the pressing block 63 and the card post 631, and improving the rationality and practicality of the structure.

[0043] As a specific implementation of the improvement, a second fixing groove 633 is opened at the bottom of the other end of the pressing block 63. An elastic member 634 is fixedly installed in the second fixing groove 633. One end of the elastic member 634 is fixedly connected to the pressing block 63, and the other end of the elastic member 634 is fixedly connected to the second slider 62.

[0044] Specifically, including but not limited to, the second fixing groove 633 is opened at one end of the pressing block 63 close to the buffer 5. The second fixing groove 633 and the elastic member 634 are respectively arranged as a circular groove and a circular spring correspondingly. At this time, the top end of the elastic member 634 is embedded in the second fixing groove 633 and fixedly connected, and the bottom end of the elastic member 634 is fixedly connected to the upper surface of the second slider 62. It should be noted that when the elastic member 634 is in a normal state, the rear end of the pressing block 63 protrudes, and the front end of the pressing block 63 is in a downward pressure state, so that the rear end of the pressing block 63 is reset under the elastic force of the elastic member 634 after being pressed. In this embodiment, the elastic member 634, the pressing block 63 and the second slider 62 are set as a split structure. Of course, the elastic member 634 can also be set as an integral structure with the pressing block 63 or the second slider 62, which is convenient for the quick installation of the pressing block 63. It should be noted that the rear end of the pressing block 63 can be in contact with the inner wall of the second slider 62 under the elastic force of the elastic member 634 in the normal state, further limiting the pressing block 63.

[0045] Through the above scheme, the second fixing groove 633 can limit and fix the elastic member 634, so that the rear end of the pressing block 63 is reset after being pressed, realizing that the rear end of the pressing block 63 rises to drive the front end to press down, or the rear end presses down to drive the front end to rise, improving the rationality and practicality of the structure.

[0046] As a specific improvement embodiment, a connecting column 635 for fixedly connecting with the second slider 62 is arranged at the center of the pressing block 63, and both ends of the connecting column 635 are inserted into the inner wall of the boss 622.

[0047] Specifically, including but not limited to, a through hole for the connecting column 635 to pass through is opened at the center of the pressing block 63. The connecting column 635 is arranged at the center of the side wall surface of the pressing block 63. Thus, after passing through the whole pressing block 63, it is inserted into the inside of the boss 622 of the second slider 62, and the diameter of the connecting column 635 is smaller than the diameter of the through hole of the pressing block 63, facilitating the pressing block 63 to rotate relative to the connecting column 635.

[0048] Through the above scheme, both ends of the connecting column 635 are inserted into the inner wall of the boss 622 after passing through the pressing block 63, which can limit and fix the pressing block 63 and realize the fixed connection between the second slider 62 and the pressing block 63.

[0049] As a specific improvement embodiment, the pressing block 63 is further provided with a recess 636, and the recess 636 is arranged below the connecting column 635. A convex bump 624 is arranged in the receiving groove 623, and the convex bump 624 is arranged below the corresponding recess 636. The recess 636 corresponds to the convex bump 624, and the pressing block 63 is placed above the convex bump 624, so that the pressing block 63 rotates along the connecting column 635 to form a seesaw structure.

[0050] Specifically, including but not limited to, both the convex hull 624 and the recess 636 are arc-shaped structures. The convex hull 624 protrudes upward from the upper surface of the second slider 62, and the convex hull 624 is disposed at the center of the receiving groove 623. The recess 636 is recessed inward from the lower surface of the pressing block 63, and the recess 636 is disposed at the center of the pressing block 63. The convex hull 624 and the recess 636 correspond to each other. Thus, when the pressing block 63 is received in the receiving groove 623, the convex hull 624 and the recess 636 fit together. The pressing block 63 is placed above the convex hull 624, and the pressing block 63 can rotate along the connecting column 635 and cooperate with the convex hull 624 to form a seesaw structure, so that the pressing block 63 can be higher than the second slider 62. In this embodiment, the arc-shaped matching structure of the convex hull 624 and the recess 636 can of course also be set according to actual applications.

[0051] Through the above solution, the setting of the convex hull 624 and the recess 636 can form a seesaw structure for the pressing block 63, which is convenient for the flexible adjustment and positioning of the pressing block 63.

[0052] As a specific embodiment of the improvement, a plurality of convex marks 637 are provided on the upper surfaces of both ends of the pressing block 63.

[0053] Specifically, including but not limited to, the convex marks 637 are rectangular bars and there are 6 of them, and the 6 convex marks 637 are disposed on the upper surface of the pressing block 63 corresponding to the elastic member 634. The convex marks 637 can increase friction and prevent slipping when the pressing block 63 is pushed forward after being pressed downward. Of course, the number, position and structure of the convex marks 637 can also be set according to actual requirements.

[0054] As a specific embodiment of the improvement, a fixing column 612 is provided at the front end of the first slider 61, and the fixing column 612 is fixedly connected to the rocker arm 2.

[0055] Specifically, including but not limited to, the fixing column 612 is a circular column, the fixing column 612 and the first slider 61 are of an integral structure, and a through hole can be provided in the fixing column 612 to facilitate the connection with the rocker arm 2.

[0056] As a specific embodiment of the improvement, a fixing rod 625 is provided at the rear end of the second slider 62, and the fixing rod 625 is fixedly connected to the buffer 5.

[0057] Specifically, including but not limited to, two parallel vertical rods are further provided at the rear end of the second slider 62. Both ends of the fixing rod 625 are fixed between the two vertical rods. A through hole is provided at the front end of the piston rod of the buffer 5, and the fixing rod 625 passes through the through hole so that the buffer 5 and the fixing rod 625 are fixedly connected. Thus, the second slider 62 and the piston rod of the buffer 5 are linked. When the second slider 62 moves in an embedded manner, the piston rod can be driven to extend. At the same time, the buffer 5 is also fixedly installed inside the connecting arm 4.

[0058] Finally, it should be noted that the above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. Any technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
