Description

Technical Field

[0001] This invention relates to the field of buffer technology, and in particular to a sliding door buffer structure. Background Technology

[0002] Sliding doors are common home furnishing products. When using sliding doors, inertial pushing and impact often occur, causing the sliding door to collide with the frame. This can result in noise, incomplete closing of the sliding door, and damage to the sliding door structure. To avoid excessive noise when the sliding door hits the frame while sliding, and to prevent damage to the door leaf and frame, the following measures are taken.

[0003] Existing solutions typically involve installing a damper on sliding doors. This damping component, in conjunction with a return spring assembly, achieves slow and silent door closure, significantly improving safety and comfort. The core structure of existing dampers mainly consists of a mounting base, a hydraulic damping component, a return spring, and a hook assembly. The mounting base has a groove to guide the hook assembly's sliding motion. The hook assembly has two protrusions that engage with a trigger element. The entire door opening and closing process relies on the coordinated operation of these mechanisms. The specific operating principle is as follows: During closing, the door moves the damper synchronously. When the door closes to the preset buffer stroke, the protrusions of the hook assembly press against the stationary trigger element on the track, fixing the hook assembly relatively in place, and the door, along with the damper... The entire shock absorber continuously slides relative to the hook, thereby compressing the internal damping component. At this time, the damping component generates a constant throttling resistance, which cancels out the sliding inertia of the door leaf, enabling the door leaf to move slowly. At the same time, the return spring pulls the hook to continue moving in the closing direction until the door closes silently. When the door opens, because the trigger and the hook are against each other, the door leaf and the buffer slide in the opposite direction relative to the hook, which then stretches the return spring. Therefore, the user needs a lot of force to overcome the elastic resistance of the return spring. Until the hook is pulled to the sliding bend of the slide groove, when the hook slides to the sliding bend at the end of the slide groove, it flips downward, causing the trigger and the hook to disengage from each other, and the buffer returns to the initial standby state. To ensure that buffers can pull heavy door panels, current buffers can only be paired with high-force springs. The greater the spring force and the stronger the stored tension, the more effectively the buffer can pull the closing force of heavy doors, preventing incomplete buffering. Especially with the widespread use of large-sized, heavy glass doors and solid wood sliding doors, the sliding inertia of the door panels has increased significantly. To ensure the practicality of the buffer, existing buffers can only meet the needs by matching with a return spring with even greater tension. However, this requires users to exert more force to pull the return spring to open the door. Conversely, if a low-force spring is chosen to reduce the force required to open the door and improve the user experience, its stored tension will be greatly reduced, making it difficult to overcome the sliding resistance when closing the door. Therefore, current buffers have a technical pain point: "high tension performance inevitably corresponds to high opening resistance," and the two cannot be reconciled and optimized, creating an irreconcilable technical contradiction. Summary of the Invention

[0004] The present invention provides a sliding door buffer structure to solve the above-mentioned industry pain points.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sliding door buffer structure, comprising an opening reset component and a closing trigger component disposed on a first mounting surface, a buffer base disposed on a second mounting surface, and at least one slider and a linkage hook. The slider is slidably assembled within the buffer base and is connected to a damping component and a return spring. The upper side of the slider is provided with an A hook portion and a B hook portion, which are offset from each other. The A hook portion corresponds to the opening reset component, and the B hook portion corresponds to the closing trigger component, thereby forming a clearance area corresponding to the opening reset component and the closing trigger component. The linkage hook is hinged to the slider and slides synchronously with the slider on the buffer base. The buffer base has a lifting groove for the linkage hook to slide, allowing the linkage hook to be raised or retracted on the buffer base. The raised linkage hook engages with the B hook portion to form a locking structure against the closing trigger component, and the retracted linkage hook releases the locking structure against the closing trigger component.

[0006] Furthermore, one end of the linkage hook is hinged to the lower part of the B hook of the slider through a hinge hole, and the other end is provided with a C hook and a sliding column. When the linkage hook is in the raised state, the C hook protrudes out of the buffer base, and the protruding C hook cooperates with the B hook to form a hooking structure for the door closing trigger.

[0007] Furthermore, the buffer base has a sliding groove for the slider to slide in, the sliding groove has a sliding bend, and the lifting groove includes a high section in the middle and low sections at both ends, the high section extending through the low sections at both ends; when the slider slides in the sliding groove, the linkage hook slides in the high section of the lifting groove, causing the linkage hook to remain in an elevated state; when the slider is at the end of the sliding groove, the linkage hook is in the low section of the lifting groove, causing the linkage hook to remain in a retracted state.

[0008] Furthermore, the buffer base includes a frame plate, and the slider, linkage hook, damping component and reset spring are all disposed within the frame plate. The slide groove and lifting groove are disposed on the frame plate. The slider is provided with sliding pins at both ends, and the two sliding pins are respectively located below the A hook part and the B hook part. The slider is slidably connected to the slide groove through the two sliding pins. The linkage hook is slidably connected to the lifting groove through a sliding column, causing the linkage hook to move synchronously with the slider and to lift or retract and swing.

[0009] Furthermore, the first mounting surface is provided with a magnetic suction component A, and the end of the buffer base is provided with a magnetic suction component B. When the door is in the closed state, the magnetic suction components A and B attract each other to restrict the movement of the door.

[0010] Furthermore, along the door's closing sliding direction, the door opening reset component is located in front of the door closing trigger component.

[0011] Furthermore, when there are two sliders, the A hook and the door opening reset component are both higher than the B hook. The damping component and the reset spring are driven and connected between the two sliders. The door opening reset component, the door closing trigger component, the A magnetic attraction component, and the B magnetic attraction component are all provided in pairs.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The A hook and B hooks arranged on the slider allow the door closing trigger to pass through the avoidance area via the A hook and push the B hook to slide relative to the opening direction. Simultaneously, the linkage hook on one side of the slider slides synchronously. The lifting linkage hook and the B hook limit the door closing trigger, preventing it from detaching from the slider. When the door is closed, after the slider and linkage hook have completed a one-way stroke, the linkage hook retracts into the buffer base, releasing the limit on the door closing trigger. When the door is opened, the door closing trigger does not participate in the slider's operation. The buffer slides freely in the opening direction, and the door opening reset member, after passing the B hook, abuts against the A hook and pushes the slider relative to the closing direction until it returns to its original position.

[0013] By configuring the door opening reset component and the door closing trigger component to cooperate with the slider of the buffer, and equipped with a damping component and a return spring, the buffer can provide stable damping to the door leaf to counteract the sliding inertia of the door leaf when the sliding door is closed. When the door is opened, the door leaf and the buffer slide together in the opening direction. After sliding a certain distance, the buffer cooperates with the door opening reset component, and uses the energy stored inertia of the door leaf to overcome the elasticity of the return spring to assist the buffer to return to the initial standby state. This reduces the user's pulling force burden when opening the door, effectively ensuring that the high performance of the buffer can counteract the sliding inertia of the door leaf, while allowing the user to open the door easily.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0025] As attached Figure 1-7 As shown in Figures 9 and 1, the present invention provides a sliding door buffer structure, including an opening reset component 2 and a closing trigger component 1 disposed on a first mounting surface, a buffer base 4 disposed on a second mounting surface, and at least one slider 5 and a linkage hook 6; see reference. Figure 1The first mounting surface refers to the mounting surface of the door frame track, and the second mounting surface refers to the mounting surface on the upper side of the door leaf. It can also be installed in reverse, with the buffer installed in the track and the trigger installed on the door leaf. Referring to the structure of existing buffers, the slider 5 is slidably assembled within the buffer base 4 and connected to a damping element 7 and a return spring 8. Both the return spring 8 and the damping element 7 are located within the buffer base 4. The upper side of the slider 5 is provided with an A hook portion 51 and a B hook portion 52. Note that in existing structures, the A hook portion 51 and B hook portion 52 are generally in a center-corresponding state, and they mutually constitute a limiting structure for the trigger to prevent it from detaching. Specifically, the A hook portion 51 and B hook portion 52 are misaligned, with the A hook portion 51 corresponding to the door opening reset element 2. Hook 52 (B) is fitted to the door closing trigger 1, thus forming a clearance area corresponding to the door opening reset 2 and the door closing trigger 1. The linkage hook 6 is hinged to the slider 5 and slides synchronously with the slider 5 on the buffer base 4. The buffer base 4 has a lifting groove 412 for the linkage hook 6 to slide, allowing the linkage hook 6 to be raised or retracted on the buffer base 4. The raised linkage hook 6, in conjunction with hook 52 (B), forms a locking structure against the door closing trigger 1. The retracted linkage hook 6 releases this locking structure. Hook 51 (A) and hook 52 (B) are offset from each other and do not overlap, thus forming a clearance area corresponding to the door closing trigger 1 and the door opening reset 2. Specifically, the door opening reset 2 is located on the projection area corresponding to hook 51 (A); the door closing trigger 1 is located on the projection areas corresponding to hook 52 (B) and hook 61 (C). Furthermore, the door opening reset component 2 and the door closing trigger component 1 also have corresponding avoidance areas for the A hook portion 51 and the B hook portion 52, respectively; that is, the A hook portion 51 will not collide when passing the door closing trigger component 1, and the B hook portion 52 will not collide when passing the door opening reset component 2, or the door opening reset component 2 is higher than the B hook portion 52, so that the B hook portion 52 will not collide when passing the door opening reset component 2. On this basis, in order to prevent the risk of the door closing trigger component 1 and the slider 5 from disengaging, a linkage hook 6 is hinged on one side of the slider 5. The linkage hook 6 is provided with a C hook portion 61. One end of the linkage hook 6 is slidably engaged with the buffer base 4, so that the linkage hook 6 can be raised or retracted. The C hook portion 61 on the linkage hook 6 in the raised state cooperates with the B hook portion 52 to form a hooking and limiting structure for the door closing trigger component 1.

[0026] The principle and effect of the sliding door buffer structure of the present invention are as follows: by setting the A hook part 51 and the B hook part 52 off-center on the slider 5, when the door is in the open state, the slider 5 is tilted in the sliding bend part 4111 at the end of the slide groove 411. It can be compared with the structure of the existing sliding door buffer. In this state, the A hook part 51 and the C hook part 61 are both in the buffer base 4, which is the initial state. When the door closes, the misalignment of hook A 51 creates two clearance areas, allowing the door closing trigger 1 to pass through hook A 51 and hook C 61, and to push hook B 52 to slide relative to the opening direction. This causes slider 5 to flip upward and disengage from the sliding bend 4111 of the slide groove 411. At this time, hook A 51 protrudes from the buffer base 4. As slider 5 slides synchronously, it drives linkage hook 6, causing linkage hook 6 to slide and simultaneously lift out of the buffer base 4. The lifted linkage hook 6 limits the door closing trigger 1 through hook C 61 and hook B 52 to prevent the door closing trigger 1 from disengaging from slider 5. When the door is closed, slider 5 and linkage hook 6 complete a one-way stroke, hook C 61 retracts into the buffer base 4, releasing the limit on the door closing trigger 1 and preventing it from affecting the opening process. When the door is opened, the closing trigger 1 will not cooperate with the slider 5, so the door leaf and the buffer base 4 can be easily pulled in the opening direction. The opening reset component 2 can pass through the avoidance area to the B hook part 52 and push the A hook part 51 to slide relative to the closing direction. At the same time, it drives the linkage hook 6 set on one side of the slider 5 to slide synchronously. The opening reset component 2 pushes the slider 5 to the sliding bend 4111 at the end of the slide groove 411. The slider 5 near the sliding pin 53 below the A hook part 51 flips down and hooks into the sliding bend 4111. At this time, due to the tilt of the slider 5, the opening reset component 2 is disengaged from the A hook part 51. At the same time, the sliding column 62 of the linkage hook 6 slides into the lower section 4122 of the lifting groove 412 and retracts into the buffer base 4. The buffer returns to the initial standby state. By configuring the door opening reset component 2 and the door closing trigger component 1 to cooperate with the slider of the buffer, and equipped with the damping component 7 and the return spring 8, the buffer can provide stable damping to the door leaf to counteract the sliding inertia of the door leaf when the sliding door is closed. When the door is opened, the door leaf and the buffer slide together in the opening direction. After sliding a certain distance, the buffer cooperates with the door opening reset component 2 to overcome the elastic force of the return spring 8 by using the sliding inertia of the door leaf. The buffer returns to the initial standby state with the help of the inertial force of the door leaf, reducing the pulling burden of the user when opening the door. This effectively ensures that the high performance of the buffer can counteract the sliding inertia of the door leaf, while allowing the user to open the door easily.

[0027] Specifically, the slider 5 has a hinge post 54 located below the hook portion 52 (B). One end of the linkage hook 6 is hinged to the hinge post 54 of the slider 5 through a hinge hole 63. Alternatively, the hinge hole 63 can be set on the slider 5 in the opposite direction, and the hinge post 54 can be set on the linkage hook 6. The other end of the linkage hook 6 has a hook portion 61 (C) and a sliding post 62. When the linkage hook 6 is in the raised state, the hook portion 61 (C) protrudes from the buffer base 4. The protruding hook portion 61 cooperates with the hook portion 52 to form a hooking structure for the door closing trigger 1, preventing the door closing trigger 1 from detaching from the buffer.

[0028] Specifically, the buffer base 4 has a slide groove 411 for sliding the slider 5. The slide groove 411 has a sliding bend 4111. The lifting groove 412 includes a high section 4121 in the middle and low sections 4122 at both ends. The high section 4121 extends through the low sections 4122 at both ends. When the slider 5 slides in the slide groove 411, the sliding post 62 of the linkage hook 6 slides in the high section 4121 of the lifting groove 412, causing the linkage hook 6 to remain in a raised state. When the slider 5 is at the end of the slide groove 411, the sliding post 62 of the linkage hook 6 is in the low section 4122 of the lifting groove 412, causing the linkage hook 6 to remain in a retracted state. The buffer base 4 includes a frame plate 41. The slider 5, linkage hook 6, damping element 7, and reset spring 8 are all disposed within the frame plate 41. The slide groove 411 and lifting groove 412 are disposed on the frame plate 41, with the lifting groove 412 located below the slide groove 411. The slider 5 has sliding pins 53 at both ends, with the two sliding pins 53 located below hook A 51 and hook B 52, respectively. The slider 5 is slidably connected to the slide groove 411 via the two sliding pins 53. The linkage hook 6 is slidably connected to the lifting groove 412 via a sliding column 62, causing the linkage hook 6 to move synchronously with the slider 5 and to lift or retract and swing. The sliding pin 53 protrudes from the front and rear sides of the slider 5 along the thickness direction and is inserted into the sliding groove 411 on the two frame plates 41. The slider 5 slides in the sliding groove 411 through the sliding pin 53. The two sliding pins 53 make the slider 5 stable during the sliding process. The sliding groove 411 is mainly used for the sliding pin 53 of the slider 5 to slide. The sliding bend 4111 at its end is used for the sliding pin 53 at one end of the slider 5 to fall off, so that the slider 5 tilts when it slides to the end of the sliding groove 411, so that the hook part A tilts and retracts into the buffer base 4, thereby realizing the separation of the door opening reset part 2 and the slider 5. When slider 5 slides in groove 411, linkage hook 6 slides in the high guide section, causing linkage hook 6 to remain in an elevated state; when slider 5 is at the end of groove 411, linkage hook 6 is in the low guide section, causing linkage hook 6 to remain in a retracted state; lifting groove 412 is used to cooperate with linkage hook 6 to realize the lifting and retraction of linkage hook 6 on buffer base 4. When slider 5 is stationary at the left end of groove 411, linkage hook 6 is located in the low guide section on the left. At this time, linkage hook 6 is in a retracted state, that is, inside buffer base 4, and will not contact door closing trigger 1. As slider 5 slides to the right end, it drives linkage hook 6, causing linkage hook 6 to be pulled from the low section to the high section. At this time, it is in an elevated state. At the same time, hook C 61 and hook B 52 engage with each other to prevent door closing trigger 1 from falling off slider 5. Finally, slider 5 slides to the right end, and linkage hook 6 slides synchronously to the low section on the right end, that is, returns to the retracted state. (See reference) Figure 9The hinge pin 54 can be mounted on the linkage hook 6 or the slider 5, and a hinge hole 63 is correspondingly provided on the linkage hook 6 or the slider 5. The hinge hole 63 and the hinge pin 54 are used to achieve mutual hinge connection between the two. For further explanation, the overall shape of the lifting groove 412 is shown in the figure. Figure 3 A transition section exists between the low-position guide section and the high-position guide section, with an angle of less than 90° between the transition section and the high-position guide section and the low-position guide section, ensuring smooth sliding of the sliding column 62. The clamping plate is provided with a strip-shaped groove corresponding to the sliding groove 411, for sliding engagement of the sliding pin 53 located below the hook part 52 of B. The sliding pin 53 is used to connect the two frame plates 41 and the clamping plate in series, allowing the sliding pin 53 to slide smoothly.

[0029] The closing trigger 1 works in conjunction with the slider 5, utilizing the damping element 7 and the return spring 8 connected to the slider 5 to provide buffering and pulling force to the door leaf when closing. The opening reset element 2 works in conjunction with the slider 5 to help the slider 5 return to its initial state, preparing for the next closing. Specifically, along the closing sliding direction of the door leaf, the opening reset element 2 is located in front of the closing trigger 1, that is, the opening reset element 2 is closer to the center of the track than the closing trigger 1. This allows the door leaf and the buffer to slide together for a certain distance before engaging with the opening reset element 2. The sliding inertia of the door leaf overcomes the elastic force of the return spring 8, and the inertial force of the door leaf assists the buffer to return to its initial standby state, reducing the burden on the user when opening the door.

[0030] To further prevent the door from rebounding after closing, the first mounting surface is provided with an A magnetic attractor 3, and the end of the buffer base 4 is provided with a B magnetic attractor 42. When the door is closed, the A magnetic attractor 3 and the B magnetic attractor 42 attract each other to restrict the movement of the door. Specifically, the end of the buffer base 43 is provided with a B magnetic attractor 42, and the first mounting surface is provided with an A magnetic attractor 3. The A magnetic attractor 3 and the B magnetic attractor 42 correspond to each other and attract each other. In conjunction with the use of the buffer, when the door is closed, the door is locked in the closed position by the mutual attraction between the B magnetic attractor 42 and the A magnetic attractor 3, which can further prevent the door from rebounding after closing. Both the A magnetic attractor 3 and the B magnetic attractor 42 can be implemented using existing magnets.

[0031] Specifically, when the slider 5 is in a sliding state, the A hook portion 51 and the B hook portion 52 on the upper side of the slider 5 are misaligned. The A hook portion 51 is correspondingly engaged with the door opening reset component 2, and the B hook portion 52 is correspondingly engaged with the door closing trigger component 1, thereby forming a clearance area corresponding to the door opening reset component 2 and the door closing trigger component 1. This allows the door closing trigger component 1 to pass through the clearance area of ​​the A hook portion 51 and enter between the C hook portion 61 and the B hook portion 52. One end of the door closing trigger component 1 abuts against the B hook portion 52, and the C hook portion 61 of the linkage hook 6 abuts against the other end of the door closing trigger component 1, forming a hooking and limiting structure for the door closing trigger component 1, thereby locking the door closing trigger component 1 onto the slider 5.

[0032] When the door is opened, the door opening reset component 2 can pass through the area of ​​the B hook part 52 and push the A hook part 51 to slide relative to the closing direction. At the same time, it drives the linkage hook 6 set on one side of the slider 5 to slide synchronously. The door opening reset component 2 pushes the slider 5 to the sliding bend 4111 at the end of the slide groove 411, and the sliding pin 53 near the A hook part 51 of the slider 5 flips down and hooks into the sliding bend 4111. At this time, the door opening reset component 2 is disengaged from the A hook due to the tilt of the slider 5.

[0033] In embodiment two, if the only purpose is to provide a buffering effect for the door leaf when closing, the slider 5 can be configured as a single slider. A corresponding groove 411 is provided on the front section of the frame plate 41. The front end of the groove 411 has a sliding bend 4111. The slider 5 slides within the groove 411 and is connected to the damping member 7 and the return spring 8. The other end of the damping member 7 and the return spring 8 is connected to the buffer base 4 and is located away from the front end of the groove 411. That is, one end of the damping member 7 and the return spring 8 is limited to the rear end of the buffer base 4, and the slider 5 is slidably mounted on the front end of the buffer base 4. Further explanation: This structure can be used for both unidirectional and bidirectional buffering.

[0034] In embodiment three, to achieve a buffering function for both the opening and closing states of the door, two sliders 5 are provided. When there are two sliders 5, the A hook portion 51 can be set higher than the B hook portion 52, and the door opening reset component 2 can be set higher than the B hook portion 52, so that the door opening reset component 2 will not contact the B hook portion 52 when passing through it, ensuring that the door opening reset component 2 and the B hook portion 52 do not affect each other. The damping component 7 and the reset spring 8 are driven and coordinated between the two sliders 5. The door opening reset component 2 and the door closing trigger component 1 are both... The system is configured with two components: a door-closing trigger 1 and a door-opening reset 2, located on the left side of the first mounting surface (track), and a door-closing trigger 1 and a door-opening reset 2, located on the right side of the first mounting surface. The buffering mechanism operates on the same principle as the door-closing mechanism when the door is open. Two sliders 5 are provided, located at both ends inside the buffer base 4 and connected to the damping element 7 and the reset spring 8. One slider 5 is connected to the fixed end of the damping element 7, and the other slider 5 is connected to the movable end of the damping element 7. The reset spring 8 is connected to both sliders 5. In the initial state, the two sliders 5 are located at both ends of the buffer base 4 and within the sliding bend 4111 of the slide groove 411. Based on this, two sliding grooves 411 are symmetrically provided at both ends of the frame plate 41. The ends of the two sliding grooves 411 that are far apart from each other are provided with downwardly bent sliding parts 4111, and are correspondingly equipped with two linkage hooks 6 and lifting grooves 412. The lifting grooves 412 are set on the same end and side of the frame plate 41 corresponding to the linkage hooks 6. One linkage hook 6 is set on the front side of one of its sliders 5, and the frame plate 41 is provided with a lifting groove 412 on the same side of the slider 5. The other linkage hook 6 is set on the rear side of the other slider 5. At the same time, the two ends of the first mounting surface are also symmetrically provided with door opening reset parts 2, door closing trigger parts 1 and A magnetic suction parts 3, and both ends of the buffer base 4 are provided with B magnetic suction parts 42, which are used to cooperate with A magnetic suction parts 3 respectively. The two door opening reset parts 2 are located in the middle.

[0035] The above embodiments are preferred embodiments of the present invention. Any structures similar to those of the present invention and equivalent changes thereof should fall within the protection scope of the present invention.
