Description

Technical Field

[0001] This invention relates to the technical field of hardware accessories, and in particular to a hinge with controllable cushioning. Background Technology

[0002] Hinges are accessories mounted on devices such as doors, windows, and cabinets that require relative rotation. They typically consist of two or more moving parts. Hinges allow the moving parts of an object to rotate relative to a fixed part. Cup hinges are a type of hinge, usually installed on cabinets to allow the cabinet door to rotate relative to the cabinet body. Cup hinges include a cup head and an arm; the cup head is hinged to the arm and can rotate relative to it. Cup hinges usually have a damping component. When the cup head rotates relative to the arm, the damping component acts as a buffer, reducing the impact force when the door closes towards the cabinet body, thus providing damping and cushioning for the rotation between the door and the cabinet body. In practical use, the buffer component can buffer the movement of the cup head and the arm body in each relative rotation. However, the user cannot set whether to use the buffer function, resulting in poor customization of the hinge's buffer function. Consequently, the user cannot turn off the buffer function to increase the relative rotation speed between the cup head and the hinge, causing the opening and closing speed of the door panel and cabinet to remain unchanged. This is especially true for door panels and cabinets with multiple sets of hinges, where the buffer function of multiple sets of hinges collectively results in a slow opening and closing speed. The user cannot turn off the buffer function of one or more sets of hinges to increase the opening and closing speed of the door panel and cabinet. Therefore, this invention provides a hinge with controllable buffering. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a hinge with controllable buffering.

[0004] To achieve the above objectives, this invention discloses a controllable buffer hinge, comprising a cup head, an arm body, a buffer member, a sliding member, and a blocking member. The cup head is hinged to the arm body, the buffer member is mounted on the cup head, the sliding member is slidably connected to the cup head, and the sliding member abuts against the telescopic portion of the buffer member. The blocking member is mounted on the cup head and slidably disposed on one side of the sliding member. When the blocking member is in a first position, during the rotation of the arm body and the cup head relative to each other towards the closing direction, the sliding member moves to drive the telescopic portion of the buffer member, and the buffer member applies a buffering force to achieve the buffering effect of the hinge. When the blocking member is slidably adjusted to a second position, the blocking member always abuts against the sliding member, and the blocking member locks the position of the sliding member to disable the buffering effect of the buffer member.

[0005] A further embodiment is that the blocking member and the sliding member abut against the front end of the sliding member.

[0006] A further embodiment is that the front side of the slider is provided with a clearance groove, which extends from front to back. The blocking member is adjusted to align with the clearance groove to activate the buffering function of the buffer member.

[0007] A further embodiment includes a cam and an elastic element. The cam is rotatably connected to the cup head, one end of the elastic element abuts against the cup head, and the other end of the elastic element and the cam abut against both sides of the blocking element, so as to drive the blocking element to move between abutting against the front end of the sliding element and disengaging from the front end of the sliding element.

[0008] A further embodiment is that the blocking member has a seat and an arm, the arm extends upward from the top surface of the seat, and a stop head protrudes from the side of the arm facing the slider, the stop head abutting against the front end of the slider or disengaging from the front end of the slider.

[0009] A further embodiment is that the stop abuts against the front end of the slider or is fitted into the relief groove.

[0010] A further embodiment is that the elastic element is a compression spring, and the blocking element is further provided with a stop portion. The stop portion is connected to the bottom surface of the blocking element, and a sleeve strip is provided on the side of the stop portion facing the elastic element. The elastic element abuts against the stop portion, and the sleeve strip is located inside the elastic element.

[0011] A further embodiment is that when the blocking member is in the first position, the stop head corresponds to and can be fitted into the clearance groove; when the blocking member is in the second position, the stop head is offset from the clearance groove and abuts against the front end of the blocking member.

[0012] A further embodiment is that the seat portion has a first receiving groove, the extension direction of the first receiving groove is the same as that of the elastic member, the side portion of the elastic member is received in the first receiving groove, and the fitting strip extends to the bottom side of the first receiving groove.

[0013] A further embodiment is that a second receiving groove is provided on the bottom surface of the cup with the cup head facing downwards, the first receiving groove and the second receiving groove are corresponding to each other and extend in the same direction, and the elastic element is installed between the first receiving groove and the second receiving groove.

[0014] A further embodiment is that the cup head is provided with a limiting hook, which is located on the top side of the seat to restrict the movement of the blocking member toward the top side.

[0015] A further embodiment includes an adjusting screw that extends from the outside of the cup head to the inside of the cup head and is connected to the cam to drive the cam to rotate.

[0016] A further embodiment is that the bottom surface of the cup head is provided with a rotation limiting block to limit the rotation angle of the cam. The rotation limiting block is located on the outside of the cam, and the cam has a blocking surface that abuts against the rotation limiting block.

[0017] A further embodiment is that the side of the seat facing the cam is an arc surface, and the arc surface is adapted to the arc-shaped side of the cam.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: When the arm and cup head rotate relative to each other in the closed state, the damping component slides and applies a buffering force to the arm and cup head. By adjusting the position of the blocking component, when the arm and cup head rotate relative to each other in the closed state, the sliding component will not slide along with it, thereby limiting the movement of the extension and retraction part of the damping component. By limiting the movement of the extension and retraction part of the buffer component, the opening and closing of the buffering effect of the hinge is controlled. Specifically, by limiting the sliding of the sliding component connected to the extension and retraction part of the buffer component and transmitting the buffering force, the opening and closing of the buffering effect is realized. This allows the user to set whether to use the buffering effect of the hinge, and also improves the customization of the buffering effect of the hinge. By closing the buffering effect, the relative rotation speed between the cup head and the hinge is increased, thereby increasing the opening and closing speed of the door panel and the cabinet. Especially when multiple sets of hinges are installed in the same set of door panels and cabinets, the buffering effect of multiple sets of hinges works together to buffer the opening and closing of the door panel and the cabinet. The user can increase the opening and closing speed of the door panel and the cabinet by closing the buffering effect of one or more sets of hinges. By setting a cam and an elastic element, the elastic element being a compression spring, rotating the cam causes the blocking element to engage with the relief groove to activate the buffering effect. When the buffering effect needs to be deactivated, the cam is rotated again, and the elastic element applies a force to the blocking element, driving the blocking element to move so that the blocking element abuts against the outside of the sliding element to deactivate the buffering effect. Through the above settings, the blocking element is driven to move between aligning with the relief groove and deviating from the relief groove to switch the activation and deactivation of the buffering effect. After driving the blocking element, the elastic element allows the blocking element to reset. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the following will be combined with... Figure 1-9 The state shown is described in terms of orientation and structure.

[0022] Example 1: Refer to Figure 1-9As shown, a controllable buffer hinge includes a cup head 11, an arm 15, a buffer 16, a slider 17, a stopper 23, and an outer cover 31. The cup head 11 is mounted on the movable part of the cabinet, and the arm 15 is mounted on the fixed part of the cabinet. The cup head 11 and the arm 15 are hinged, allowing the movable part of the cabinet to rotate around the fixed part. The buffer 16 is mounted on the cup head 11, and the buffer 16 provides a buffering effect when the movable part of the cabinet rotates around the fixed part towards the closed state. The slider 17 abuts against the telescopic part of the buffer 16, and the slider 17 moves with the buffer... The telescopic part of component 16 slides synchronously, the blocking part 23 can detach from or abut against one side of the sliding part 17, the outer cover 31 is installed on the outside of the cup head 11, and the buffer part 16, the sliding part 17, and the blocking part 23 are installed between the cup head 11 and the outer cover 31. The arm body 15 rotates relative to the cup head 11 toward the closing direction, so as to drive the sliding part 17 to abut against the telescopic part of the buffer part 16. The buffer part 16 applies a buffering force, and the rotation direction of the buffering force is opposite to the rotation direction of the arm body 15 and the cup head 11, so as to achieve a buffering effect when the cup head 11 and the arm body 15 rotate toward the closed state.

[0023] Because the buffer 16 applies a buffering force through the slider 17 when the cup head 11 and arm body 15 rotate toward the closed state, the slider 17 will slide whenever the cup head 11 and arm body 15 rotate relative to each other. When the cup head 11 and arm body 15 are in the closed state, the buffer 16 is compressed, and the slider 17 slides to position a, i.e. Figure 7 The slider 17 is positioned at position a. When the cup head 11 and arm body 15 are in the open state, the buffer 16 extends, and the slider 17 slides to position b, i.e. Figure 3 , 4 The slider 17 shown is in position b. When the user wants to disable the buffering effect, the position of the blocking member 23 is adjusted so that the blocking member 23 is in the second position, i.e. Figure 7 The blocking member 23 is located in the second position, abutting against the sliding member 17, thus blocking the sliding member 17 at position a. The sliding member 17 no longer slides with the rotation of the cup head 11 and the arm body 15, and the telescopic part of the buffer member 16 no longer moves. That is, the sliding member 17 is blocked at position a, thereby closing the buffering effect between the arm body 15 and the cup head 11. Specifically, the blocking member 23 overcomes the buffering force of the buffer member 16 through the sliding member 17, thus keeping the sliding member 17 stationary. When the user wants to activate the buffering effect, the blocking member 23 is adjusted to the first position, such as... Figure 3 , 4 The blocking element 23 shown is in the first position, that is, the buffering function is in the open state.

[0024] With the above settings, users can customize whether to use the hinge's buffering effect, thus increasing the customization of the hinge's buffering effect. By turning off the buffering effect, the relative rotation speed between the door cup and the hinge can be increased, thereby increasing the opening and closing speed of the door panel and the cabinet. This is especially true for door panels and cabinets with multiple sets of hinges installed in the same group, where the buffering effect of multiple sets of hinges works together to buffer the opening and closing of the door panel and the cabinet. Users can increase the opening and closing speed of the door panel and the cabinet by turning off the buffering effect of one or more sets of hinges.

[0025] The specific connection relationship between the slider 17 and the buffer 16 of the present invention can be referred to the patent document with publication number CN120575748A. The difference between the present invention and the patent document is that the spring in the above patent document is replaced with the buffer 16.

[0026] The slider 17 is slidably connected to the outside of the cup head 11. Specifically, the slider 17 is installed on the outside of the bottom surface of the cup-shaped part of the cup head 11. The buffer 16 and the blocking part 23 are installed on the cup head 11. When the cup head 11 and the arm body 15 rotate relative to each other, the telescopic part of the buffer 16 installed on the cup head 11 transmits the buffering force to the slider 17. The slider 17 slides on the outside of the cup head 11 and abuts against the arm body 15. The buffering force is then transmitted to the arm body 15 through the slider 17, thereby realizing the transmission of the buffering force.

[0027] The blocking member 23 abuts against the front end of the sliding member 17. When the cup head 11 and the arm body 15 are in the closed state, the sliding member 17 slides to position a. By blocking the sliding member 17 at position a, when the cup head 11 and the arm body 15 are rotated to the open state, the blocking member 23 will not move to position b. Thus, when the cup head 11 and the arm body 15 are rotated to the closed state, the sliding member 17 will no longer abut against the arm body 15, and the buffer member 16 will no longer produce a buffering effect.

[0028] When the buffering function is turned off, the blocking member 23 is not engaged with the relief groove 18, but is located and abuts against the front end of the sliding member 17, thereby restricting the sliding of the sliding member 17. The relief groove 18 is provided on the front side of the sliding member 17, and the relief groove 18 extends from front to back. When the buffering function needs to be turned on, the blocking member 23 is adjusted so that the blocking member 23 is partially engaged with the relief groove 18. The blocking member 23 is aligned with the relief groove 18, and the relief groove 18 provides clearance for the sliding of the sliding member 17, so that the sliding member 17 can slide between position a and position b to turn on the buffering function of the buffer member 16.

[0029] The invention also includes a cam 19 and an elastic element 21. The cam 19 is rotatably connected to the cup head 11. One end of the elastic element 21 abuts against the cup head 11, and the other end of the elastic element 21 abuts against both sides of the blocking element 23, respectively. The cam 19 abuts against the blocking element 23 and drives the blocking element 23 to slide. Rotating the cam 19 causes the blocking element 23 to engage in the relief groove 18 to activate the buffering effect. When it is necessary to deactivate the buffering effect, the cam 19 is rotated again, and at the same time, the elastic element 21 applies a force to the blocking element 23, driving the blocking element 23 to move, so that the blocking element 23 abuts against the outside of the sliding element 17 to deactivate the buffering effect. Through the above settings, the blocking element 23 is driven to move between the aligned relief groove 18 and the deviated relief groove 18 to switch the activation and deactivation of the buffering effect.

[0030] The blocking member 23 is provided with a seat 24 and an arm 26. The arm 26 extends upward from the top surface of the seat 24. The arm 26 has a stop head 27 protruding from the side of the sliding member 17. The stop head 27 abuts against the sliding member 17 or is fitted into the relief groove 18. The elastic member 21 and the cam 19 drive the arm 26 to slide by driving the seat 24. The arm 26 drives the stop head 27 to slide, thereby abutting against the sliding member 17 or fitting into the relief groove 18.

[0031] When the blocking member 23 is in the first position, the stop head 27 corresponds to and can be fitted into the clearance groove 18, and the buffering effect is in the open state; when the blocking member 23 is in the second position, the stop head 27 is offset from the clearance groove 18 and abuts against the front end of the blocking member 23, and the buffering effect is in the closed state.

[0032] The elastic element 21 is a compression spring, and the blocking element 23 is also provided with an arc-shaped abutment 28. The abutment 28 is connected to the bottom surface of the seat 24. The abutment 28 has a sleeve 29 protruding from the side of the elastic element 21. The elastic element 21 abuts against the abutment 28 and the sleeve 29 is located inside the elastic element 21.

[0033] The seat 24 has a first receiving groove 25. The extension direction of the first receiving groove 25 is the same as that of the elastic member 21. The side of the elastic member 21 is accommodated in the first receiving groove 25, and the sleeve strip 29 extends to the bottom side of the first receiving groove 25.

[0034] The bottom surface of the cup head 11 is provided with a second receiving groove 12. The first receiving groove 25 corresponds to the second receiving groove 12 and extends in the same direction. The elastic member 21 is installed between the first receiving groove 25 and the second receiving groove 12. One end of the elastic member 21 facing the abutment 28 abuts against the abutment 28, and the elastic member 21 is sleeved on the outside of the fitting strip 29, thereby realizing the installation of the elastic member 21.

[0035] The cup head 11 is provided with a limiting hook 13, which is located on the top side of the seat 24. Specifically, the limiting hook 13 extends from the side wall of the cup head 11 to the top side of the seat 24 to restrict the movement of the blocking member 23 toward the top side. The cam 19 and the elastic member 21 drive the seat 24 to slide between the limiting hook 13 and the second receiving groove 12.

[0036] The invention also includes an adjusting screw 22, which extends from the outside of the cup head 11 to the inside of the cup head 11 and is connected to the cam 19 to drive the cam 19 to rotate. The user can adjust the rotation of the cam 19 by rotating the adjusting screw 22 to achieve the switching of the buffer function on and off.

[0037] The cam 19 has a blocking surface 20, and the bottom surface of the cup head 11 has a protruding limit block 14 to limit the rotation angle of the cam 19. The limit block 14 is located on the outside of the cam 19. The cam 19 has a blocking surface 20, which abuts against the limit block 14 to limit the rotation angle of the cam 19. When the user rotates the cam 19, the elastic element 21 drives the seat 24 to slide. When the blocking surface 20 of the cam 19 abuts against the limit block 14, the stop head 27 abuts against the front end of the sliding element 17 to close the buffering effect. When the user rotates the cam 19, the seat 24 slides to squeeze the elastic element 21. When the blocking surface 20 of the cam 19 moves away from the limit block 14, and the rotation of the cam 19 is resisted, the stop head 27 aligns with the relief groove 18 to open the buffering effect.

[0038] The side of the seat 24 facing the cam 19 is an arc surface 30, which is adapted to the arc-shaped side of the cam 19 to improve the smoothness of the cam 19 when rotating.

[0039] Example 2: The difference between this example and Example 1 is that this example uses a different method to abut against the sliding member 17, thereby blocking the sliding member 17 at position a, thus achieving the closing of the buffering effect, as shown below. Figure 10 , 11 In this embodiment, the blocking member 23 is replaced by the push-pull member 32, that is, the push-pull member 32 replaces the function of the blocking member 23. The rear end of the sliding member 17 is provided with a wing 33, and the outer cover 31 has an opening. The push-pull member 32 passes through the opening and can slide in the opening. The front end of the push-pull member 32 can abut against the wing 33 or disengage from the wing 33. When the front end of the push-pull member 32 abuts against the wing 33, the buffering function of the hinge is in the closed state. When the front end of the push-pull member 32 disengages from the wing 33, the buffering function of the hinge is in the open state. Before installing the hinge onto the furniture, the user can pre-operate the push-pull member 32 in the closed state according to the hinge assembly scenario, that is, pre-operate the push-pull member 32 in the state where the sliding member 17 is in position a, to select whether the hinge buffering function is closed, and then install the hinge onto the furniture to realize the closing and opening of the hinge buffering function.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They cannot be used to limit the scope of protection of the present invention. All modifications made according to the spirit of the main technical solution of the present invention should be covered within the scope of protection of the present invention.
