DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0029] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0030] In the description of the embodiments of the present utility model, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0031] Please refer to Figure 1-Figure 3 , Figure 1 This is a structural schematic diagram of an implementation method of the magnetic attraction structure of the door body provided by the utility model. Figure 2 This is a structural schematic diagram of another implementation method of the magnetic attraction structure of the door body provided by the utility model. Figure 3 This is a structural schematic diagram of another implementation method of the magnetic attraction structure of the door body provided by the utility model.

[0032] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a magnetic attraction structure 200 for a door body. It should be known that the door body includes a door panel, which is usually rectangular, although circular or other complex shapes are not excluded. The door panel can be, for example, a wooden door panel, a metal door panel, or a door panel of other composite materials, etc. In other words, the material and structure of the door panel are not limited in the embodiment of the utility model. The magnetic attraction structure 200 can be specifically installed at the outer edge of the door panel so as to be attracted to the door frame.

[0033] Specifically, the magnetic attraction structure 200 includes a base 210 and a magnetic attraction portion 220. The base 210 is made of metal. The base 210 includes an integrated main body 211 and a connecting portion 212. An installation chamber 211a is formed in the main body 211. The magnetic attraction portion 220 is arranged in the installation chamber 211a. The connecting portion 212 is used to connect to the door panel.

[0034] In the above solution, the base 210 of the magnetic structure 200 is made of metal. Compared with the plastic material in the prior art, the metal material is not prone to aging, shrinkage and other problems. When used, especially under long-term conditions, the magnetic structure 200 can be well attached to the door frame and is not prone to gaps due to material deformation. In addition, the metal base 210 can also improve the texture of the magnetic structure 200, which has positive significance for improving product competitiveness and user experience.

[0035] The base 210 of the magnetic structure 200 is an integrally formed one-piece structure, which is provided with an installation chamber 211a, and the magnetic part 220 is inserted in the installation chamber 211a. The overall structural form is relatively simple. After the installation is completed, the magnetic structure 200 can form a complete structure, the magnetic part 200 is located in the base 210, and the magnetic part 220 is basically not exposed, which can largely avoid the situation where the magnetic part 220 is damaged by human or accidental damage, which is conducive to ensuring the long-term effectiveness of the magnetic structure 200; the base 210 located on the outside is a single material, which can avoid the separation phenomenon caused by different weather resistance of multiple materials (for example, in the background technology, the magnet and plastic are co-extruded, which will cause the magnet and plastic to be exposed at the same time, which is easy to cause the separation phenomenon).

[0036] When it is necessary to connect to the door panel, the magnetic structure 200 can be connected to the door panel as a whole through the connecting portion 212, without the need for step-by-step installation as described in the background technology section, and the installation process is relatively simple.

[0037] Here, the embodiment of the utility model does not limit the specific type of metal material used by the substrate 210. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, the substrate 210 can be made of aluminum alloy, which has a relatively low mass density and is conducive to achieving lightweight. The aluminum alloy substrate 210 can be specifically prepared by extrusion or stretching.

[0038] In addition, the embodiment of the utility model does not limit the connection method between the connection part 212 and the door panel. In practical applications, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use. For example, the connection part 212 and the door panel can be connected by interference plug-in, bonding, air nail connection, screw connection, clamping, etc., as long as it can meet the reliability requirements of the connection and other design requirements.

[0039] In some optional implementations, the connecting portion 212 may be an interference fit portion, and a mounting groove portion may be provided on the door panel. The connecting portion 212 is configured to be able to be interference fitted in the mounting groove portion, thereby achieving interference insertion between the magnetic attraction structure 200 and the door panel.

[0040] In this implementation, there is no need to set connecting components such as air nails between the magnetic structure 200 and the door panel, so that the connection structure and connection method between the two can be relatively simple. At the same time, interference fit itself is also a reliable fixed connection method, which basically does not affect the reliability of the connection between the two. More importantly, after the installation is completed, the connection part 212 will be hidden in the installation groove, that is, the connection part 212 will basically not be exposed, which is very beneficial to improving the appearance of the door body, thereby improving the competitiveness of the product and helping to improve the user experience.

[0041] Please continue to refer to Figure 1 The connection part 212 may include a connection plate 212a and a protrusion 212b. The connection plate 212a is a carrier of the protrusion 212b. The protrusion 212b may be formed on the connection plate 212a, and may be located on one or both sides of the normal direction of the connection plate 212a. The connection part 212 may be interference fitted through the protrusion 212b. With such a configuration, it is not necessary to thicken the entire connection part 212, which is conducive to saving materials.

[0042] The protrusion 212 b may be a convex dot-shaped structure, a convex block-shaped structure, a convex plate-shaped structure, or the like.

[0043] In the implementation of the accompanying drawings, Figure 1-Figure 3 As shown, the protrusion 212b can be a convex plate-shaped structure, which can extend in the same direction as the main body 211, and the protrusion 212b can gradually tilt toward the main body 211 from the direction away from the connecting plate 212a; Figure 1-Figure 3 The orientation and position relationship in the figure is used as a reference, that is, the protrusion 212b gradually tilts leftward from bottom to top. In this way, when the connecting part 212 is inserted into the installation groove of the door panel, the inclined protrusion 212b can also have a certain guiding effect, which is more conducive to the insertion of the connecting part 212 into the installation groove; and after the insertion is completed, the inclined protrusion 212b can also play a certain non-returning role, and can also prevent the connecting part 212 from escaping from the installation groove to a certain extent, which can ensure the reliable connection between the connecting part 212 and the door panel to a greater extent.

[0044] exist Figure 1 and Figure 2 In the embodiment, the number of the protrusions 212b may be two, and the two protrusions 212b may be arranged on the connecting plate 212a at intervals. Figure 3 In the embodiment, the number of the protrusion 212b may be only one, and the protrusion 212b may be provided at an end of the connecting plate 212a relatively far from the main body 211. In addition, the number of the protrusion 212b may also be greater, which is not limited here.

[0045] It should be understood that the above-mentioned method of providing the protrusion 212b on the connecting plate 212a and realizing the interference fit through the protrusion 212b is only an exemplary description of the embodiment of the utility model, and cannot be used as a limitation on the implementation scope of the magnetic attraction structure 200 provided by the utility model. Under the condition of satisfying the function, the connecting part 212 can also be set to other structural forms. For example, the connecting part 212 can also include only the connecting plate 212a. In this case, the thickness of the connecting plate 212a can be increased so as to directly perform the interference fit through the connecting plate 212a.

[0046] In some optional implementations, the inner wall surface of the main body 211 may be further provided with a limiter 211b, and the limiter 211b is configured to limit the magnetic attraction portion 220. In this way, the installation reliability of the magnetic attraction portion 220 in the installation chamber 211a can be improved, and the shaking of the magnetic attraction portion 220 in the installation chamber 211a and the noise generated thereby can be reduced.

[0047] The main body 211 may include a sealing plate 211 c . Specifically, the main body 211 may be attached to the door frame through the sealing plate 211 c to achieve sealed contact between the door body and the door frame.

[0048] The installation chamber 211a may include a first sub-chamber 211a-1 and a second sub-chamber 211a-2, and the first sub-chamber 211a-1 and the second sub-chamber 211a-2 are arranged in sequence in a direction away from the sealing plate 211c, and the first sub-chamber 211a-1 is closer to the sealing plate 211c than the second sub-chamber 211a-2. The magnetic attraction portion 220 may be installed in the first sub-chamber 211a-1 and may fit with the sealing plate 211c. The stopper 211b may be located in the second sub-chamber 211a-2 and may abut against the magnetic attraction portion 220, so as to better ensure the reliable fit between the magnetic attraction portion 220 and the sealing plate 211c.

[0049] In this implementation, the installation chamber 211a is larger than the magnetic part 220, and the magnetic part 220 can only occupy part of the space in the installation chamber 211a. When the magnetic part 220 is inserted and assembled in the installation chamber 211a, the contact area between the magnetic part 220 and the inner wall surface of the main body 211 is relatively small, which can reduce the friction force of the magnetic part 220 when assembled in the main body 211, and can reduce the difficulty of assembling the magnetic part 220 in the installation chamber 211a. In addition to being used to set the limiter 211b, the rest of the second sub-chamber 211a-2 can be left empty to serve as an energy-absorbing gap, which can effectively absorb the collision energy between the door body and the door frame during the closing process, thereby protecting the magnetic structure 200 and reducing the possibility of collision damage. In addition, for some doors with a high degree of automation, such as doors equipped with smart locks, the space in the second sub-chamber 211a-2 can also be used for wiring. On the one hand, the space in the second sub-chamber 211a-2 can be utilized, and on the other hand, cables such as transmission lines and signal lines can be hidden, which can reduce the impact of the external environment on these cables.

[0050] It should be understood that the sizes of the magnetic attraction portion 220 and the installation chamber 211a may also be substantially the same, for example Figure 2 and Figure 3 As shown, at this time, the magnetic attraction portion 220 can basically completely fill the installation chamber 211a. The size of the magnetic attraction portion 220 is relatively large, which can provide a relatively larger magnetic attraction force, which is of positive significance for ensuring the reliability of the door body closing.

[0051] The limiter 211b is Figure 1-Figure 3 In the figure, the convex blocks are relatively small in size, so that the space occupied by the installation chamber 211a can be reduced. In addition, the stopper 211b can also be set to other structural forms, such as a plate-like structure, which can be set between the first sub-chamber 211a-1 and the second sub-chamber 211a-2, and can also achieve isolation between the first sub-chamber 211a-1 and the second sub-chamber 211a-2.

[0052] At least a portion of the surface of the sealing plate 211c facing away from the installation chamber 211a can be used to fit with the door frame, and this surface for fitting with the door frame can be called a sealing surface 211c-2.

[0053] The sealing surface 211c-2 can be a complete surface.

[0054] Or, if Figure 1-Figure 3As shown, the sealing plate 211c may also be provided with a separation groove 211c-1, which may separate the sealing surface 211c-2 into a plurality of sealing facets 211c-2a. The sealing plate 211c may specifically be in contact with the door frame through each sealing facet 211c-2a. By adopting this implementation method, the area of ​​each sealing surface 211c-2a is relatively small. During the specific manufacturing, the flatness of each sealing surface 211c-2a is relatively easy to ensure, which can reduce the difficulty of processing the sealing plate 211c; and, dividing the sealing surface 211c-2 into multiple sealing surface 211c-2a is equivalent to dividing a seal between the sealing part 211c and the door frame into multiple seals, which is also of positive significance for ensuring the sealing reliability of the contact between the sealing plate 211c and the door frame; in addition, the above-mentioned separation groove 211c-1 can also play a certain decorative role, which can enhance the aesthetics and texture of the magnetic suction structure 200 provided by the utility model, and is conducive to enhancing product competitiveness and user experience.

[0055] The number of the dividing grooves 211c-1 is not limited here, and can be determined according to actual usage requirements.

[0056] Still Figure 1-Figure 3 As shown, the main body 211 may include a first plate 211d and a second plate 211e in addition to the sealing plate 211c. The sealing plate 211c, the first plate 211d and the second plate 211e may be connected to each other to form a main body 211 in a substantially triangular prism shape. During specific installation, the first plate 211d and the second plate 211e may be connected to the door panel.

[0057] In some optional implementations, the main body 211 may also be integrally formed with two shielding parts. For ease of description, in the embodiment of the utility model, the two shielding parts may be respectively referred to as a first shielding part 213 and a second shielding part 214. The first shielding part 213 and the second shielding part 214 may extend in the same direction as the main body 211. During specific installation, the first shielding part 213 and the second shielding part 214 may both be used to shield the joint between the main body 211 and the door panel to prevent external water vapor, impurities, etc. from entering the joint, thereby achieving a better moisture-proof and anti-fouling effect.

[0058] When the magnetic structure 200 provided in the embodiment of the utility model is connected to the door panel, each connection point can also be filled with a colloid so as to glue the magnetic structure 200 and the door panel, thereby ensuring the reliability requirements of the connection to a greater extent. For example, for the aforementioned connecting portion 212, in addition to being connected to the door panel by means of interference fit, glue can also be applied on the connecting portion 212 to better fix it by means of gluing. For another example, for the aforementioned first plate 211d, second plate 211e, first masking portion 213 and second masking portion 214, gluing can be further adopted to improve the reliability of the connection.

[0059] Please refer to Figure 4 and Figure 5 , Figure 4 This is a partial structural diagram of the door body provided by the utility model. Figure 5 for Figure 4 Schematic diagram of the structure of the middle door panel.

[0060] The embodiment of the utility model further provides a door body, including a door panel 100 and a magnetic attraction structure 200. The magnetic attraction structure 200 is the magnetic attraction structure 200 involved in the aforementioned implementations, and the magnetic attraction structure 200 can be connected to the door panel 100 through a connecting portion 212 to achieve a fixed connection between the magnetic attraction structure 200 and the door panel 100, and the specific fixed connection method includes but is not limited to interference fit, bonding, air nail connection, screw connection, clamping, etc.

[0061] In a specific example, Figure 4 and Figure 5 As shown, the door panel 100 has a normal panel surface 130 and a lateral panel surface 140. The outer edge of the door panel 100 may be provided with a notch portion 110, which may be located at a corner where the normal panel surface 130 and the lateral panel surface 140 meet. The notch portion 110 may include a first mounting surface 111 and a second mounting surface 112. The door panel 100 may also be provided with a mounting groove portion 120, which may be connected to the notch portion 110.

[0062] During specific installation, the main body 211 can be located in the notch portion 110, the connecting portion 212 can be interference fitted in the mounting groove portion 120, the first plate 211d can be connected to the first mounting surface 111, the second plate 211e can be connected to the second mounting surface 112, the first covering portion 213 can be connected to the normal plate surface 130, and the second covering portion 214 can be connected to the side plate surface 140.

[0063] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
