Description

Technical Field

[0001] This utility model relates to the field of furniture, specifically providing a door with damping buffer. Background Technology

[0002] Most room doors are equipped with door catches, which are used to fix the door to the wall by magnetic attraction or other means, keeping the door open.

[0003] Current door catch assembly includes a fixing component and a magnetic component. The magnetic component is fixed to the door body, and the fixing component is fixed to the wall. The magnetic component consists of a base, a magnetic part, and a spring. The spring is located between the magnetic part and the base. When the door body is opened, the magnetic part first impacts the fixing component, and the impact energy is absorbed by the spring and then released. However, if the door opens too quickly, the thrust generated after the energy absorbed by the spring is released will be greater than the magnetic attraction between the magnetic part and the fixing component, causing the door body to bounce off and fail to achieve the purpose of magnetic fixation.

[0004] Therefore, there is an urgent need for a door with damping buffer to solve the problem that existing doors may bounce back after being opened. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that existing doors may bounce back after being opened.

[0006] In a first aspect, this utility model provides a door with damping buffer, including a door body and a magnetic suction assembly. The magnetic suction assembly includes: a fixing structure, including a fixing member, a moving member, and an elastic reset member; the fixing member has a cavity; the moving member is installed in the cavity and can reciprocate along the length direction of the fixing member; the elastic reset member is located in the cavity, one end of the elastic reset member abuts against the fixing member, and the other end abuts against the moving member; the fixing member is fixed to a wall, and a one-way valve and an air hole are provided on the side wall of the fixing member; the one-way valve is configured to allow air to flow out from the cavity; the air hole connects the cavity and the external space of the fixing member, and the diameter of the air hole is smaller than the diameter of the one-way valve; and a magnetic suction structure, fixed to the door body, wherein the magnetic suction structure aligns with the moving member when the door body is opened.

[0007] By adopting the above technical solution, after the magnetic attraction structure comes into contact with the fixed structure, the kinetic energy of the door body during the opening process will drive the moving part to move towards the fixed part, compressing the air in the cavity. The air in the cavity is then quickly discharged through the one-way valve. The elastic reset part is quickly compressed to absorb the kinetic energy of the door body, reducing the impact force of the magnetic attraction structure on the fixed structure. During the release of elastic potential energy, the elastic reset part pushes the moving part away from the fixed part and draws air into the cavity from the outside through the air hole. Since the resistance of air entering the cavity through the air hole is relatively large, it can effectively consume the elastic potential energy of the elastic reset part, reduce the rebound speed of the moving part, and thus reduce the pushing force exerted by the moving part on the magnetic attraction structure. This reduces the possibility of the magnetic attraction structure detaching from the fixed structure, that is, reduces the possibility of the door body rebounding.

[0008] In the specific embodiment of the door with damping buffer described above, the magnetic attraction structure includes a base, an elastic energy-absorbing element, and a magnetic element. The base is fixed to the door body and has a receiving cavity. The magnetic element is located in the receiving cavity, and the elastic energy-absorbing element is located between the magnetic element and the base. The maximum elastic force of the elastic energy-absorbing element is less than the maximum magnetic attraction force between the magnetic element and the moving element.

[0009] By adopting the above technical solution, during the process of the magnetic attraction structure impacting the fixed structure, the elastic energy-absorbing component can also absorb some energy, and the energy absorbed by the elastic energy-absorbing component will be released first, thereby reducing the possibility of the magnetic attraction structure detaching from the fixed structure, that is, reducing the possibility of the door body rebounding.

[0010] In the specific embodiment of the door with damping buffer described above, the maximum energy absorbed by the elastic energy-absorbing member is less than the maximum energy absorbed by the elastic reset member.

[0011] In the specific embodiment of the door with damping and buffering described above, the elastic energy-absorbing element is a rubber buffer or a spring.

[0012] In the specific embodiment of the door with damping buffer described above, the elastic reset element is a spring.

[0013] In the specific embodiment of the door with damping buffer described above, the portion of the moving member away from the fixed member is tapered, and the end of the moving member away from the fixed member is a ball head. The magnetic attraction structure includes a magnetic attraction element, and the surface of the magnetic attraction element away from the door body has a groove, with the ball head engaging with the groove.

[0014] By adopting the above technical solution, the contact area between the magnetic component and the moving component can be increased, thereby increasing the maximum magnetic attraction between the magnetic component and the moving component.

[0015] In the specific embodiment of the door with damping and buffering described above, the surface of the ball head is covered with buffer rubber.

[0016] By adopting the above technical solution, the cushioning rubber can reduce the noise generated by the collision between the ball head and the magnetic component.

[0017] In the specific embodiment of the door with damping and buffering described above, the buffer rubber is sleeved on the surface of the ball head.

[0018] By adopting the above technical solution, the cushioning rubber can be easily replaced after it is damaged.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a door with damping buffer, including a door body and a magnetic suction assembly. The magnetic suction assembly includes: a fixing structure, including a fixing member, a moving member, and an elastic reset member. The fixing member has a cavity, the moving member is installed in the cavity and can reciprocate along the length of the fixing member, and the elastic reset member is located in the cavity, with one end abutting against the fixing member and the other end abutting against the moving member; the fixing member is fixed to the wall, and the side wall of the fixing member is provided with a one-way valve and an air hole. The one-way valve is configured to allow air to flow out from the cavity, and the air hole connects the cavity and the external space of the fixing member. The diameter of the air hole is smaller than the diameter of the one-way valve; the magnetic suction structure is fixed to the door body, and the magnetic suction structure aligns with the moving member after the door body is opened. After the magnetic attraction structure comes into contact with the fixed structure, the kinetic energy of the door body during the opening process will drive the moving part to move towards the fixed part, compressing the air in the cavity. The air in the cavity will then be quickly discharged through the one-way valve. The elastic reset part is quickly compressed to absorb the kinetic energy of the door body, reducing the impact force of the magnetic attraction structure on the fixed structure. During the release of elastic potential energy, the elastic reset part pushes the moving part away from the fixed part and draws air from the outside into the cavity through the air hole. Since the resistance of air entering the cavity through the air hole is relatively large, it can effectively consume the elastic potential energy of the elastic reset part, reduce the rebound speed of the moving part, and thus reduce the pushing force exerted by the moving part on the magnetic attraction structure. This reduces the possibility of the magnetic attraction structure detaching from the fixed structure, that is, reduces the possibility of the door body rebounding. Attached Figure Description

[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1 As shown, this utility model provides a door with damping buffer, including a door body 1 and a magnetic suction assembly. The magnetic suction assembly includes a fixing structure 2 and a magnetic suction structure 3. The magnetic suction structure 3 is fixed to one side of the door body 1 near the bottom, and the fixing structure 2 is fixed to the wall. When the door body 1 is opened and close to the wall, the magnetic suction structure 3 contacts the fixing structure 2, and the magnetic attraction between the magnetic suction structure 3 and the fixing structure 2 fixes the door body 1 to the wall, thus keeping the door body 1 in the open state. The fixing structure 2 is equipped with a damping buffer structure to dissipate the absorbed rebound energy, reduce the rebound speed of the door body 1, and reduce the possibility of the door body 1 rebounding.

[0030] Specifically, such as Figure 2As shown, the fixing structure 2 includes a fixing member 21, a moving member 22, and an elastic reset member 23. The fixing member 21 has a cavity 211. The moving member 22 is installed in the cavity 211 and can reciprocate along the length of the fixing member 21. The elastic reset member 23 is located inside the cavity 211, with one end abutting against the fixing member 21 and the other end abutting against the moving member 22. The fixing member 21 is fixed to the wall. After the door body 1 is opened, the magnetic suction structure 3 aligns with the moving member 22. The side wall of the fixing member 21 is provided with a one-way valve 212 and an air hole 213. The one-way valve 212 is configured to allow air to flow out of the cavity 211. The air hole 213 connects the cavity and the external space of the fixing member 21. The diameter of the air hole 213 is smaller than the diameter of the one-way valve 212.

[0031] During the opening process of the door body 1, the magnetic attraction structure 3 impacts the moving part 22, causing the moving part 22 to move towards the fixed part 21. The moving part 22 compresses the air in the cavity 211, causing the air in the cavity 211 to be quickly discharged through the one-way valve 212. The elastic reset part 23 is quickly compressed to absorb the kinetic energy of the door body 1, reducing the impact force of the magnetic attraction structure 3 on the fixed structure 2. During the release of elastic potential energy, the elastic reset part 23 pushes the moving part 22 away from the fixed part 21, and draws air from the outside into the cavity 211 through the air hole 213. Since the resistance of air entering the cavity 211 through the air hole 213 is relatively large, it can effectively consume the elastic potential energy of the elastic reset part 23, reduce the rebound speed of the moving part 22, and thus reduce the pushing force exerted on the magnetic attraction structure 3 by the moving part 22. Once this pushing force is lower than the magnetic attraction force between the magnetic attraction structure 3 and the moving part 22, the magnetic attraction structure 3 will not detach from the moving part 22, thus reducing the possibility of the door body 1 rebounding.

[0032] For example, the inner side of the fixing member 21 has a guide groove 214 extending along the length of the fixing member 21, and the outer periphery of the moving member 22 has a protruding guide block 221. The guide block 221 cooperates with the guide groove 214 and can slide along the guide groove 214. A stop cap 24 is provided at the end of the fixing member 21 facing the moving member 22. The stop cap 24 is threaded onto the fixing member 21. The moving member 22 passes through the stop cap 24 to block the guide block 221 of the moving member 22 and prevent the moving member 22 from detaching from the fixing member 21.

[0033] As a preferred method, such as Figure 1As shown, the magnetic attraction structure 3 includes a base 31, an elastic energy-absorbing element 32, and a magnetic element 33. The base 31 is fixed to the door body 1 and has a receiving cavity 311. The magnetic element 33 is located inside the receiving cavity 311, and the elastic energy-absorbing element 32 is located between the magnetic element and the base 31. The maximum elastic force of the elastic energy-absorbing element 32 is less than the maximum magnetic attraction force between the magnetic element 33 and the moving element 22. During the process of the magnetic attraction structure 3 impacting the fixed structure 2, the elastic energy-absorbing element 32 can also absorb some energy, and the energy absorbed by the elastic energy-absorbing element 32 will be released first, thereby reducing the possibility of the magnetic attraction structure 3 detaching from the fixed structure 2, that is, reducing the possibility of the door body 1 rebounding.

[0034] In addition, the maximum energy absorbed by the elastic energy-absorbing component 32 is less than the maximum energy absorbed by the elastic reset component 23. In other words, the kinetic energy of the door body 1 is mainly absorbed by the elastic reset component 23, while the elastic energy-absorbing component 32 only plays the role of assisting in energy absorption and early release, thereby increasing the maximum energy absorbed by the magnetic attraction component.

[0035] In a specific example of this utility model, the elastic energy-absorbing component 32 is a rubber buffer or a spring, and the elastic reset component 23 is a spring.

[0036] In a specific example of this utility model, such as Figure 2 As shown, the portion of the movable member 22 away from the fixed member 21 is tapered, and the end of the movable member 22 away from the fixed member 21 is a ball head. The surface of the magnetic member away from the door body 1 has a groove, and the ball head mates with the groove. This increases the contact area between the magnetic member and the movable member 22, thereby increasing the maximum magnetic attraction between them.

[0037] For example, the surface of the ball head is covered with cushioning rubber, which reduces the noise generated by the collision between the ball head and the magnetic component. The cushioning rubber can be fitted onto the surface of the ball head for easy replacement if it is damaged.

[0038] In summary, the working process of the damping and buffering door provided by this utility model is as follows:

[0039] During the opening process of the door body 1, the magnetic attraction structure 3 impacts the moving part 22, causing the moving part 22 to move towards the fixed part 21. The moving part 22 compresses the air in the cavity 211, causing the air in the cavity 211 to be quickly discharged through the one-way valve 212. The elastic reset part 23 is quickly compressed to absorb the kinetic energy of the door body 1, reducing the impact force of the magnetic attraction structure 3 on the fixed structure 2. During the release of elastic potential energy, the elastic reset part 23 pushes the moving part 22 away from the fixed part 21, and draws air from the outside into the cavity 211 through the air hole 213. Since the resistance of air entering the cavity 211 through the air hole 213 is relatively large, it can effectively consume the elastic potential energy of the elastic reset part 23, reduce the rebound speed of the moving part 22, and thus reduce the pushing force exerted on the magnetic attraction structure 3 by the moving part 22. Once this pushing force is lower than the magnetic attraction force between the magnetic attraction structure 3 and the moving part 22, the magnetic attraction structure 3 will not detach from the moving part 22, thus reducing the possibility of the door body 1 rebounding.

[0040] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
