Description

Technical Field

[0001] The present invention relates to the technical field related to door stopper damping, and particularly to a door stopper damping mechanism and a door stopper system. Background Art

[0002] With the continuous development of modern architecture and home design, as an important device for fixing the door body, the functional and reliability requirements of door stoppers are increasing day by day. A door stopper usually consists of a door stopper base (fixed to the ground or wall) and a door stopper post (fixed to the door body), and the two cooperate to achieve the locking and positioning of the door body after it is opened, so as to prevent the door body from accidentally closing due to wind force or external collision. However, the existing door stopper technologies generally have structural defects or performance deficiencies in actual applications, and it is difficult to meet the comprehensive requirements of users for smooth operation, durability, and cost control.

[0003] Currently, the mainstream types of door stoppers on the market include column type, suction plate type, vertical and horizontal type, and electromagnetic and electric type, but all have significant limitations: the electromagnetic and electric door stopper has high manufacturing costs and complex installation and maintenance; the column type door stopper has a large impact force at the moment of suction, which is easy to cause the door body to collide violently with the door frame, and long-term use may cause the door body to deform. Summary of the Invention

[0004] In order to overcome at least one of the above-mentioned defects of the existing technology, the present invention provides a door stopper damping mechanism and a door stopper system, which can solve problems such as high cost, weak anti-impact ability, and serious shaking of the door body.

[0005] The technical solution adopted by the present invention to solve its problems is as follows:

[0006] A door stopper damping mechanism includes: a housing for assembling to the back side of the door body, a guiding mechanism is provided on the housing, assuming that the side where the housing is assembled to the door body is the back of the housing, the guiding mechanism has a first end close to the back and a second end far from the back; a damper assembled in the housing; a contact member that slides along the guiding mechanism and at least partially extends out of the housing to form a clamping groove for abutting against a clamping column in the stopper. When the contact member moves towards the clamping column, the clamping groove abuts against the clamping column, so that the contact member slides along the second end of the guiding mechanism towards the first end, thereby triggering the damper.

[0007] By adopting the above solution, by introducing a damper, a progressive buffer is provided when the door body is opened to reduce the impact force. Specifically, the movement trajectory of the contact member is restricted by the guiding mechanism to ensure that the damping force direction is consistent with the movement direction of the contact member, thereby improving the suction efficiency. The damper will provide a smooth resistance to reduce the instantaneous impact force; at the same time, the damper cooperating with the guiding mechanism can improve the sliding stability and reduce the shaking of the door body.

[0008] Furthermore, the shell also includes a movable block, which is vertically slidably arranged in the shell and is located between the damper and the abutment, and the damper is vertically arranged above the movable block; the movable block is provided with a slide groove, and the slide groove gradually tilts downward from the direction away from the back to the direction close to the back; the abutment is provided with a first slider slidably arranged in the slide groove, so that when the abutment gradually moves to the side close to the back, it can slide and descend along the slide groove, and at the same time drive the movable block to move upward.

[0009] By adopting the above solution, when the movable block moves upward, the inclined surface of the slide groove cooperates with the first slider to enable the abutment to simultaneously achieve a composite movement of descending and lateral displacement during the sliding process. This motion trajectory enables the abutment to form a smooth involute path when it is separated from the clamping column, avoiding the vertical rigid separation of the traditional door stopper, reducing friction loss between components, and extending the service life.

[0010] Furthermore, the guide mechanism includes a first guide section and a second guide section in sequence from the direction close to the back to the direction far from the back, the first guide section is a horizontal groove, and the second guide section is an inclined groove.

[0011] By adopting the above solution, the effect of switching between the two states of the abutment member can be achieved. The design of the second section makes the direction of damping force application form an optimal angle with the inertia direction of the door body and significantly improves the energy absorption efficiency.

[0012] Furthermore, a second slider and a third slider are also provided on the abutment member, the second slider and the third slider are arranged at an interval, and the second slider and the third slider both slide along the guide mechanism.

[0013] By adopting the above solution, the second slider and the third slider realize two stable abutment points, which can maintain the stable abutment effect of the abutment member on the guide mechanism.

[0014] Further, when the abutment member is located at the first end of the guide mechanism, the connecting line of the second slider and the third slider is parallel to the first guide section, and when the abutment member slides from the first end to the second end of the guide mechanism, at least one of the second slider and the third slider slides from the first guide section to the second guide section.

[0015] By adopting the above solution, the second slider and the third slider are spaced apart to form a double-pivot guide structure, and the three-point positioning control is realized in cooperation with the segmented guide mechanism. During the whole cycle of the door opening / closing, the second slider and the third slider always maintain two contact points engaged with the guide mechanism, effectively suppressing the deflection and shaking of the abutment during the movement, and ensuring accurate alignment at the moment of damping triggering.

[0016] Further, the clamping groove is a U-shaped groove. When the abutting member slides back and forth between the first end and the second end, the clamping posts respectively abut against both sides of the U-shaped groove.

[0017] By adopting the above solution, the abutting linkage effect is improved, and at the same time, enough clearance is reserved, which is beneficial to the smooth clamping of the clamping groove.

[0018] Further, a reset member is further included. When the abutting member is between the first end and the second end, the reset member provides a reset force for the abutting member to slide towards the first end.

[0019] By adopting the above solution, when the door body is opened with a small force, the abutting member first contacts the clamping post. Since the opening force of the door is not large, the abutting member may not be able to directly overcome the damping force of the damper to achieve locking. Therefore, the reset member plays a role and can pull the abutting member to continue sliding, thereby compressing the damper so that the abutting member remains stable within the second end.

[0020] Further, a fitting is also provided between the housing and the door body. The fitting includes: a first fitting plate for fixing to the door body; a second adjusting plate, one side of which is clamped to the first fitting plate and the other side is clamped to the housing; and a fastener for fixedly assembling the first fitting plate, the second adjusting plate and the housing.

[0021] By adopting the above solution, the assembly stability between the housing and the door body can be improved.

[0022] Further, the fitting further includes an adjusting member arranged in parallel with the fastener. The first fitting plate is provided with an abutting portion corresponding to the adjusting member, and the adjusting member is used to adjust the relative height between the housing and the first fitting plate.

[0023] By adopting the above solution, the vertical height of the door stopper damping mechanism can be finely adjusted by rotating the adjusting member, and different working conditions such as door body sinking or ground unevenness can be adapted without disassembly and reinstallation. The adjustment process does not require professional tools, significantly improving the construction efficiency.

[0024] A door stopper system includes a door body, a stopper and a door stopper damping mechanism assembled to the back side of the door body. The stopper is assembled on the wall or the ground at the rear side of the door body, and a rotatably connected clamping post is arranged on the stopper for abutting against the abutting member to trigger damping when the door body is opened.

[0025] By adopting the above solution, good shock absorption and damping effects can be provided for the opening of the door body.

[0026] In summary, a door stopper damping mechanism and a door stopper system provided by the present invention have the following technical effects:

[0027] 1. By introducing a damper, the door body can be gradually buffered during the opening process, effectively reducing the instantaneous impact force between the door body and the door frame. This not only protects the door body from deformation caused by violent collisions but also improves the comfort and safety of use;

[0028] 2. The coordinated use of the damper and the guiding mechanism ensures the stability and accuracy of the abutting member during movement. The guiding mechanism restricts the movement trajectory of the abutting member, making the direction of the damping force consistent with the movement direction of the abutting member, thereby improving the suction efficiency and reducing the shaking phenomenon of the door body during use;

[0029] 3. Since the damper provides smooth resistance, reducing the impact and wear during the opening and closing of the door body, the service life of the door stopper system can be extended. In addition, the design of the damper also helps to reduce the noise and vibration that may occur due to long-term use;

[0030] 4. It also has lower manufacturing costs and maintenance costs, reducing the overall usage cost for users. Description of the Drawings

[0040] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples.

[0041] For the convenience of understanding the embodiments of the present invention, the following will take specific embodiments as examples and make further explanatory descriptions in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0042] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] Embodiment 1 of the present invention refers to Figures 1-8As shown, a door suction damping mechanism is disclosed, including a shell 1, an abutment 2 and a damper 4. The shell 1 is hollow inside to form a cavity 14 for accommodating the abutment 2 and the damper 4. Optionally, in order to facilitate the installation of the abutment 2 and the damper 4 in the cavity 14, a detachable cover 15 may be provided on one side or both sides of the shell 1. Specifically, the shell 1 is used to be assembled to the back side of the door body, and the side of the shell 1 assembled to the door body is set as the back of the shell 1. A guide mechanism 11 is provided on the shell 1, and the guide mechanism 11 has a first end 12 close to the back and a second end 13 away from the back. The damper 4 is assembled in the cavity 14 of the shell 1, and the abutment 2 slides along the guide mechanism 11, and at least partially extends out of the shell 1 to form a locking groove 21 for abutting with the locking column 81 in the stopper 8. When the abutment 2 moves toward the locking column 81, the locking groove 21 abuts with the locking column 81, so that the abutment 2 slides along the second end 13 of the guide mechanism 11 to the first end 12, thereby triggering the damper 4. The movement trajectory of the abutment 2 is constrained by the guide mechanism 11 to ensure that the direction of the damping force is consistent with the movement direction of the abutment 2, thereby improving the suction efficiency. The damper 4 will provide smooth resistance and reduce instantaneous impact force; at the same time, the damper 4 cooperates with the guide mechanism 11 to improve the sliding stability and reduce the shaking of the door body.

[0045] In some embodiments, a reset member 5 is also installed in the cavity 14, one end of the reset member 5 is connected to the housing 1, and the other end is transmission-connected to the abutment member 2. Preferably, the reset direction of the reset member 5 is parallel to the damping direction of the damper 4. In this embodiment 1, the damper 4 is vertically arranged longitudinally, and the reset member 5 is also vertically arranged longitudinally. When the abutment member 2 is between the first end 12 and the second end 13, the reset member 5 can provide the abutment member 2 with a reset force to slide toward the first end 12. Therefore, when the door opening force is insufficient and the abutment member 2 can only be abutted to a position away from the first end 12, the reset member 5 can provide the abutment member 2 with a continuous forward force, thereby achieving a fully open and close effect on the door body.

[0046] In Embodiment 1, in order to improve the sliding stability of the abutting member 2, a movable block 3 is further provided in the housing 1. The movable block 3 is vertically slidably arranged in the housing 1 and is located between the damper 4 and the abutting member 2, that is, the movable block 3 can move longitudinally in the cavity 14. The top end of the movable block 3 has an assembly platform 33. The damper 4 and the reset member 5 are both arranged above the assembly platform 33 of the movable block 3. Specifically, the damper 4 is vertically arranged, and a fixing frame or a clamping frame is arranged beside the damper 4. The reset member 5 is a tension spring or a spring, one end of which is connected to the top of the cavity 14 of the housing 1, and the other end is clamped to the assembly platform 33. The guiding mechanism 11 is arranged in the housing 1, specifically at a position slightly below the inner side of the cover body 15. The guiding mechanism 11 sequentially includes a first guiding section 111 and a second guiding section 112 from the direction close to the back to the direction away from the back. The first guiding section 111 is a horizontal groove, and the second guiding section 112 is an inclined groove, and the inclined direction of the inclined groove is inclined obliquely upward from the first guiding section 111. The upper half of the abutting member 2 is a sliding part, and the sliding part slides in the guiding mechanism 11. The lower half of the abutting member 2 extends outward from the bottom of the cavity 14 to form a clamping groove 21 for adapting to the clamping post 81.

[0047] The working principle of the present invention is as follows. When the door body is opened, the housing 1 on the back side of the door is driven to approach the stopper 8 behind the door synchronously. Under normal circumstances, when the engaging post 81 is not contacted, the sliding portion of the abutting member 2 is located within the second guiding section 112, that is, at the second end 13 of the guiding mechanism 11. Therefore, the lower half of the abutting member 2 extends obliquely towards the engaging post 81, and the restoring member 5 is stretched. Since the abutting member 2 is located at the top of the second guiding section 112 and cannot move upward, the abutting member 2 is relatively stable within the second guiding section 112 and can maintain the abutting member 2 in a stable extended state. When the abutting member 2 contacts the engaging post 81, the door body continues to move forward due to inertia and the assistance of the restoring member 5, so that the engaging post 81 pushes the lower half of the abutting member 2 to move along the second guiding section 112 towards the first guiding section 111. During this process, the movable member moves upward under the pulling force of the restoring member 5, and starts to trigger damping to achieve a deceleration effect after moving a certain range until the abutting member 2 is completely perpendicular to the first guiding section 111. At this time, the restoring force of the restoring member 5 also acts on the movable block 3, and the abutting member 2 below the movable block 3 stably abuts within the first guiding section 111, so that the engaging post 81 and the engaging slot 21 are stably engaged, making the whole in a stable state. When the user closes the door manually, the door body moves away from the engaging post 81, so that the upper half of the abutting member 2 moves along the first guiding section 111 towards the second guiding section 112. When it completely moves between the second guiding sections 112, the abutting member 2 is again stably abutted against the second guiding section 112 and remains relatively stable. At the same time, the engaging slot 21 of the abutting member 2 extends outwards, so that the engaging post 81 in the stopper 8 disengages from the engaging slot 21, completing the door closing action.

[0048] According to the above solution, the damping force of the damper 4 is changed from being in the same direction as the inertia of the door body in the past to being perpendicular to the inertia direction of the door body, that is, the damping force of the damper 4 is perpendicular to the inertia direction of the door body, which can greatly reduce the lateral space reserved between the back side of the door body and the wall or the ground. Thus, while normally achieving the effect of switching between the two states of the abutting member 2, the design of the second guiding section 112 and the inclined surface 321 of the movable block 3 makes the direction of the damping force form an optimal angle with the inertia direction of the door body and significantly improves the energy absorption efficiency.

[0049] In a simple solution, the movable member can be omitted, so that the damper 4 and the restoring member 5 act directly on the abutting member 2. The abutting member 2 moves along the guiding mechanism 11 and also extends out of the housing 1 under the restoring force of the restoring member 5. When acting on the engaging post 81, it compresses the restoring member 5 and triggers the damping effect of the damper 4 to achieve deceleration. The specific structure of the abutting member 2 in this solution is not specifically limited as long as it can complete the above functions. And it is optimal that the damping force of the damper 4 is perpendicular to the inertia direction of the door body.

[0050] In some embodiments, in order to further improve the smoothness and stability of the change of the abutment 2 between the two states, a slide groove 31 is provided on the movable block 3. Preferably, the slide groove 31 is provided on the side of the movable block 3 parallel to the cover body 15, and the slide groove 31 gradually tilts downward from the direction away from the back to the direction close to the back; the abutment 2 is provided with a first slider 24 slidably arranged in the slide groove 31, so that the abutment 2 can slide down along the slide groove 31 when gradually displacing to the side close to the back, and at the same time drive the movable block 3 to move up, so that the abutment 2 realizes a composite movement of descent and lateral displacement. This motion trajectory enables the abutment 2 to form a smooth involute path when it is separated from the clamping column 81, avoiding the vertical rigid separation of the traditional door stopper, reducing the friction loss between components, and extending the service life.

[0051] It should be noted that the first sliding block 24 is preferably a columnar structure, so that the first sliding block 24 can rotate while sliding in the sliding groove 31 .

[0052] In the present embodiment 1, the abutment member 2 is further provided with a second slider 25 and a third slider 26, the second slider 25 and the third slider 26 are arranged at intervals, and both the second slider 25 and the third slider 26 slide along the guide mechanism 11. When the abutment member 2 is located at the first end 12 of the guide mechanism 11, the line connecting the second slider 25 and the third slider 26 is parallel to the first guide segment 111, and when the abutment member 2 slides from the first end 12 to the second end 13 of the guide mechanism 11, the line connecting the second slider 25 and the third slider 26 is parallel to the second guide segment 112, or at least one of the second slider 25 and the third slider 26 is located at the second guide segment 112, that is, both the second slider 25 and the third slider 26 can slide onto the second guide segment 112, or the second slider 25 can slide onto the second guide segment 112, and the third slider 26 can slide to the intersection between the first guide segment 111 and the second guide segment 112. The second slider 25 and the third slider 26 are arranged at intervals to form a double-pivot guide structure, and cooperate with the segmented guide mechanism 11 to achieve three-point positioning control. In the entire cycle of the door opening / closing, the second slider 25 and the third slider 26 always maintain two contact points with the guide mechanism 11, effectively suppressing the deflection and shaking of the abutment member 2 during movement, and ensuring accurate alignment at the damping triggering moment.

[0053] It should be noted that the second slider 25 is preferably columnar, so that the second slider 25 can rotate while sliding on the guiding mechanism 11, which is beneficial to the switching between the first guiding section 111 and the second guiding section 112. The third slider 26 is selected to have a block structure with a flat bottom surface and a curved surface on the side away from the second slider 25. The design of the curved surface is similar to the columnar structure, which is beneficial to the switching between the first guiding section 111 and the second guiding section 112. The flat bottom surface is parallel to the connection line between the second slider 25 and the third slider 26, increasing the contact area with the first guiding section 111 or the second guiding section 112, thereby improving the abutting stability between the abutting member 2 and the guiding mechanism 11 in the two states.

[0054] In some embodiments, to prevent the abutting member 2 from being forced by an external object to be between the abutting plane 322 and the first guiding section 111 when the door body is in the closed state, resulting in the engaging groove 21 of the abutting member 2 not being able to face the engaging post 81, thus preventing the connection between the two and affecting the deceleration function during subsequent door opening. Specifically, the engaging groove 21 is designed at the center of the part of the abutting member 2 extending outside the housing 1. The engaging groove 21 is a U-shaped groove. When the abutting member 2 slides back and forth between the first end 12 and the second end 13, the engaging post 81 abuts against both sides of the U-shaped groove respectively. Specifically, the inward concavity of the engaging groove 21 forms two engaging arms 23 on both sides for engaging with the engaging post 81 behind the door body, enabling stable engagement with the engaging post 81. A guiding surface 22 is provided on the outer side of the engaging arm 23 away from the back of the engaging groove 21. The guiding surface 22 is used to provide a guiding force for the displacement of the engaging post 81 into the engaging groove 21, so that the guiding surface 22 can provide a guiding force for the engaging post 81. Even if the abutting member 2 fails to return to its normal position abnormally, the abutting member 2 can still be driven upward by the guiding surface 22, enabling the engaging post 81 to smoothly enter the engaging groove 21 to achieve the engaging effect. When the abutting member 2 slides from the first end 12 to the second end 13, the engaging post 81 abuts against the engaging arm 23 away from the back. When the abutting member 2 slides from the second end 13 to the first end 12, the engaging post 81 abuts against the engaging arm 23 close to the back, improving the abutting linkage effect and leaving enough clearance at the same time, which is beneficial to the smooth engagement of the engaging groove.

[0055] In some embodiments, in order to improve the connection convenience and stability between the housing 1 and the door body, a fitting 7 is provided between the housing 1 and the door body. The fitting 7 includes a first fitting plate 71, a second adjusting plate 72, and a fastener 73. The first fitting plate 71 is used to be fixed to the door body. One side of the second adjusting plate 72 is snap-connected to the first fitting plate 71, and the other side is snap-connected to the housing 1. The fastener 73 is used to fixedly assemble the first fitting plate 71, the second adjusting plate 72, and the housing 1. Specifically, in this Embodiment 1, screw holes are provided on the first fitting plate 71, and the first fitting plate 71 can be fixed to the door body by screws. A first flange 711 is provided on the side of the first fitting plate 71 away from the back. A first card slot 721 for snap-connecting with the first flange 711 is provided on the side of the second adjusting plate 72 facing the first fitting plate 71. A second flange 17 also extends outward from the edge of the side of the housing 1 facing the door body. A second card slot 722 is provided on the side of the second adjusting plate 72 facing the housing 1, and the second card slot 722 is snap-connected to the second flange 17. A locking hole 18 for installing the fastener 73 is provided near the second adjusting plate 72 at the top of the housing 1. The locking hole 18 is inclined in the direction of the door body. An avoidance hole 723 for avoiding the fixing member is provided on the second adjusting plate 72. The fastener is preferably a screw rod. When the screw rod rotates into the locking hole 18, the housing 1 and the first fitting plate 71 can be moved away from each other, thereby increasing the snap-fitting friction force between the two and the second adjusting plate 72, and further improving the assembly stability between the housing 1 and the door body.

[0056] Under normal circumstances, the snap post 81 behind the door body and the housing 1 on the back side of the door body need to be assembled accurately to achieve alignment. However, installation errors often occur during the assembly process, resulting in the inability to fit or misalignment between the two. The solution is often to reinstall, which will greatly increase the installation difficulty and installation time. For this reason, in some embodiments, the fitting 7 further includes an adjusting member 6. The adjusting member 6 is arranged in parallel with the fastener 73. The first fitting plate 71 is provided with an abutting portion 712 corresponding to the adjusting member 6. The adjusting member 6 is used to adjust the relative height between the housing 1 and the first fitting plate 71. Preferably, the adjusting member 6 is also a screw rod. After the adjusting member 6 is installed, its end will abut against the abutting portion 712 of the first fitting plate 71. When the adjusting member 6 is further rotated, the thread of the adjusting member 6 will drive the housing 1 to move upward or downward, thereby achieving a fine-tuning effect and greatly improving the installation simplicity. It enables the vertical height of the door suction damping mechanism to be finely adjusted by rotating the adjusting member 6, and can adapt to different working conditions such as door body sinking or ground unevenness without disassembly and reinstallation. The adjustment process does not require professional tools, significantly improving the construction efficiency.

[0057] In some embodiments, in order to prevent dust from accumulating in the locking hole 18 and the hole position 19 of the mounting fixture, a top cover 16 is further provided on the top of the housing 1. The top cover 16 is used to cover the locking hole 18 and the hole position 19 of the mounting fixture, and at the same time can also cover the top of the fitting 7, improving the overall aesthetics.

[0058] The present invention also relates to a door stopper system, including a door body, a stopper 8, and a door stopper damping mechanism assembled to the back side of the door body. The stopper 8 is assembled on the wall or the ground at the rear side of the door body. A rotatably connected clamping post 81 is provided on the stopper, which is used to be clamped against the abutting member 2 when the door body is opened to trigger damping, and can provide good shock absorption and damping effects for the opening of the door body.

[0059] In summary, a door stopper damping mechanism and a door stopper system provided by the present invention have the following technical effects:

[0060] 1. By introducing the damper 4, the door body can be gradually buffered during the opening process, effectively reducing the instantaneous impact force between the door body and the door frame. This not only protects the door body from deformation that may be caused by severe collision, but also improves the comfort and safety of use;

[0061] 2. The cooperation of the damper 4 and the guiding mechanism 11 ensures the stability and accuracy of the abutting member 2 during movement. The guiding mechanism 11 restricts the movement trajectory of the abutting member 2, making the direction of the damping force consistent with the movement direction of the abutting member 2, thereby improving the suction efficiency and reducing the shaking phenomenon of the door body during use;
