However, the buffering effect of the PU foam material part and the compression effect during pressing are relatively limited, unable to achieve good sealing performance, resulting in poor light shielding and weakened sound insulation effect.

[0003] Therefore, how to improve the sealing performance between the door pocket and the door leaf has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0004] In view of this, the purpose of this application is to provide a sealing component for a door structure to improve the sealing performance between the door pocket and the door leaf.

[0005] Another purpose of this application is to provide a door structure with the above-mentioned sealing component.

[0006] To achieve the above purposes, this application provides the following technical solutions:

[0007] A sealing component for a door structure includes a first sealing member and a second sealing member. Both the first sealing member and the second sealing member are elastic members, where:

[0008] The first sealing member is used to be arranged on the door pocket of the door structure. The first sealing member includes an installation part and a magnetic attraction part arranged at a preset angle. A deformation space for the deformation of the magnetic attraction part is formed between the installation part and the magnetic attraction part;

[0009] The second sealing member is used to be arranged on the door leaf of the door structure, and the second sealing member is magnetically attracted and cooperated with the first sealing member.

[0010] Optionally, in the above-mentioned sealing component, the first sealing member has a chamber formed by enclosing with a PE film, and the chamber is filled with an elastic material.

[0011] Optionally, in the above-mentioned sealing component, the installation part is provided with a connecting member, and the connecting member is used to fix the first sealing member on the door pocket.

[0012] Optionally, in the above-mentioned sealing component, the connecting member is a T-shaped structure, and the connecting member has a fixing part and a first connecting part arranged perpendicular to each other. The fixing part is located in the chamber, and the first connecting part is used to cooperate with a slot on the door pocket.

[0013] Optionally, in the above-mentioned sealing assembly, a first barb for preventing the connecting member from disengaging is provided on the first connecting portion.

[0014] Optionally, in the above-mentioned sealing assembly, the magnetic attraction portion is provided with a first magnetic attraction member, the first magnetic attraction member is located in the chamber, and the first magnetic attraction member is adhered to the PE film through a foamed double-sided adhesive.

[0015] Optionally, in the above-mentioned sealing assembly, the second sealing member includes a bracket and a second magnetic attraction member provided on the bracket, the second magnetic attraction member is magnetically coupled with the first magnetic attraction member, and a second connecting portion for cooperating with a slot on the door leaf is provided on the bracket.

[0016] Optionally, in the above-mentioned sealing assembly, a convex portion for shading is provided at the connection position between the magnetic attraction portion and the installation portion, and the convex portion is connected to the magnetic attraction portion through an arc transition;

[0017] When the second sealing member is attached to the first sealing member, the convex portion is used to abut against the door leaf.

[0018] Optionally, in the above-mentioned sealing assembly, the preset angle is γ, and 45° < γ < 90°.

[0019] A door structure includes a door frame, a door leaf, and the sealing assembly as described in any one of the above.

[0031] The core of the present application lies in providing a sealing component for a door structure to improve the sealing performance between the door frame and the door leaf.

[0032] Another core of the present application lies in providing a door structure having the above-mentioned sealing component.

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0034] The traditional magnetic seal structure of the door pocket directly supports through the hard support part and plays a buffering role through the PU foam material part. However, the buffering effect of the PU foam material part and the compression effect during pressing are relatively limited, unable to achieve good sealing performance, resulting in poor light shielding and weakened sound insulation effect.

[0035] For this reason, as Figure 1 shown, the embodiments of the present application disclose a sealing assembly for a door structure, including a first seal 100 and a second seal 200. By having a preset angle between the mounting portion 101 and the magnetic attraction portion 102 of the first seal 100, a deformation space 103 for the deformation of the magnetic attraction portion 102 is formed between the mounting portion 101 and the magnetic attraction portion 102, making the magnetic attraction portion 102 more easily press and rebound, thereby improving the sealing performance between the door pocket 300 and the door leaf 400.

[0036] Next, the sealing assembly for a door structure disclosed in the embodiments of the present application will be specifically explained and described in conjunction with Figures 1 to 4 this.

[0037] Among them, as Figures 1 to 3As shown in the figure, the first seal 100 can be made of an elastic member. The first seal 100 includes a mounting portion 101 and a magnetic attraction portion 102, and the mounting portion 101 and the magnetic attraction portion 102 are arranged at a preset angle to form a deformation space 103 between the mounting portion 101 and the magnetic attraction portion 102, so that the magnetic attraction portion 102 is more likely to rebound after being pressed and deformed in the deformation space 103, thereby being able to better fit with the second seal 200 to ensure the sealing performance. At the same time, the plasticity and fault tolerance of the first seal 100 are better, and it can play a better role in covering the deformation of the door leaf 400. When installing the sealing assembly, the first seal 100 is installed on the door frame 300 through the mounting portion 101, and at the same time, the second seal 200 is installed on the door leaf 400. When the door leaf 400 is closed, the second seal 200 on the door leaf 400 is magnetically attracted and fitted with the magnetic attraction portion 102 of the first seal 100 on the door frame 300. At this time, the magnetic attraction portion 102 can undergo a large amount of pressing deformation in the deformation space 103 formed between the mounting portion 101 and the magnetic attraction portion 102, so as to play a better buffering role for the impact of the door leaf 400 and reduce the impact noise. Since the first seal 100 is an elastic member, the magnetic attraction portion 102 rebounds under the action of the elastic force and closely fits with the second seal 200, thereby improving the sealing performance between the door frame 300 and the door leaf 400.

[0038] In some embodiments, the first seal 100 can adopt a V-shaped structure surrounded by a PE film 104 to improve the scratch and wear resistance of the first seal 100, and the first seal 100 is a hollow structure with a chamber. In order to make the first seal 100 have better resilience, an elastic material 105 can be filled in the chamber of the first seal 100. The elastic material 105 can adopt a PU foam material, so that the first seal 100 has the properties of being soft, having a low compression set rate, and good resilience performance. Thus, it is further ensured that the magnetic attraction portion 102 can quickly rebound after undergoing a large amount of pressing deformation in the deformation space 103 formed between the mounting portion 101 and the magnetic attraction portion 102, ensuring that the magnetic attraction portion 102 of the first seal 100 can quickly fit with the second seal 200, ensuring the sealing performance between the door frame 300 and the door leaf 400, and at the same time improving the buffering force of the first seal 100, which can effectively reduce the noise generated by the impact. As Figure 2 and Figure 3 shown, for the convenience of understanding, the preset angle between the mounting portion 101 and the magnetic attraction portion 102 is defined as γ, and 45° < γ < 90°. By adopting a V-notch greater than 45°, it can play a better role in covering the deformed door leaf 400.

[0039] As Figure 2 and Figure 3As shown, a connecting member 106 is provided on the installation part 101, and the first seal 100 can be fixed to the door frame 300 through the connecting member 106. The connecting member 106 can be made of metal parts such as buckles and bolts.

[0040] In some embodiments, the connecting member 106 can be made of PP material (thermoplastic synthetic resin), so that while the connecting member 106 has toughness, it can also have good resilience and is not easily detached. At the same time, as Figure 2 and Figure 3 shown, the connecting member 106 can adopt a T-shaped structure, and the connecting member 106 has a fixing part 1061 and a first connecting part 1062 that are perpendicularly arranged. The fixing part 1061 is connected to the first seal 100 and is located in the cavity of the first seal 100. In addition, a slot matching with the first connecting part 1062 is provided on the door frame 300. During installation, only by inserting the first connecting part 1062 of the connecting member 106 into the slot on the door frame 300 can the installation between the first seal 100 and the door frame 300 be realized. In order to prevent the first seal 100 from being disengaged from the slot on the door frame 300, a first barb 1063 is provided on the first connecting part 1062, and a plurality of first barbs 1063 can be arranged at intervals along the insertion direction of the first connecting part 1062, so that each first barb 1063 can limit the outward movement of the first seal 100 from the slot on the door frame 300, thereby ensuring the reliability of the connection of the first seal 100.

[0041] As Figure 2 and Figure 3 shown, the magnetic attraction part 102 is provided with a first magnetic attraction member 107, and the first magnetic attraction member 107 is located in the cavity. At the same time, the first magnetic attraction member 107 and the PE film 104 can be bonded through a foamed double-sided tape 108, so as to reduce the impact force of magnetic attraction when the door leaf 400 is closed, reduce the impact noise, and improve the service life of the sealing assembly. The second seal 200 can be made of a metal part, so that the first magnetic attraction member 107 can be magnetically matched with the second seal 200, thereby ensuring the sealing performance between the door leaf 400 and the door frame 300.

[0042] In some embodiments, as Figure 4As shown, the second seal 200 includes a bracket 201 and a second magnetic member 202 disposed on the bracket 201. The second magnetic member 202 is magnetically engaged with the first magnetic member 107. A second connecting portion 2011 is provided on the bracket 201, and a slot cooperating with the second connecting portion 2011 is provided on the door leaf 400. During installation, the second seal 200 can be installed on the door leaf 400 by simply inserting the second connecting portion 2011 into the slot on the door leaf 400. To prevent the second seal 200 from disengaging from the slot on the door leaf 400, second barbs 2012 can also be provided on the second connecting portion 2011, and a plurality of second barbs 2012 can be spaced along the insertion direction of the second connecting portion 2011, so that each second barb 2012 can limit the second seal 200 from moving outwards from the slot on the door leaf 400, thereby ensuring the reliability of the connection of the second seal 200. Among them, the first magnetic member 107 and the second magnetic member 202 can use enhanced magnets, such as neodymium iron boron magnets or samarium cobalt magnets, to ensure the stability and magnetic strength of the magnetic attraction between the first magnetic member 107 and the second magnetic member 202, thereby further ensuring the sealing performance.

[0043] To avoid light leakage after the door leaf 400 is closed, a light-shielding angle is provided on the sealing assembly. When the door leaf 400 is closed, the light-shielding angle can play a role in blocking light and covering the deformation of the door leaf 400 to a certain extent.

[0044] In some embodiments, as Figure 2 and Figure 3 shown, the light-shielding angle can be provided on the first seal 100, and the light-shielding angle is a raised portion 1021 provided at the connection position between the magnetic attraction portion 102 and the installation portion 101. When the door leaf 400 is closed, at this time the second seal 200 is attached to the first seal 100, and at the same time the raised portion 1021 abuts against the door leaf 400 and is pressed, so as to ensure the sealing performance between the door leaf 400 and the door frame 300, effectively preventing the occurrence of light leakage, and when the door leaf 400 is deformed, it can play a certain covering role, improving the aesthetics of the door leaf 400. Among them, the raised portion 1021 and the magnetic attraction portion 102 can be connected by an arc transition with a radius of 1.5 cm, thereby improving the error tolerance of the first seal 100.

[0045] It should be noted that the size of the raised portion 1021 can also be reduced according to the actual situation, as Figure 3 shown. Specifically, the position, shape and size of the raised portion 1021 can be selected according to the actual situation, and are not limited herein.

[0046] An embodiment of the present application also discloses a door structure, which includes a door frame 300, a door leaf 400, and a sealing assembly. Among them, the first seal 100 of the sealing assembly is arranged on the door frame 300, and the second seal 200 of the sealing assembly is arranged on the door leaf 400, so that when the door leaf 400 is closed, the second seal 200 is magnetically attracted and matched with the first seal 100 to ensure the sealing performance between the door leaf 400 and the door frame 300. The sealing assembly can adopt the sealing assembly for the door structure disclosed in the above embodiment, and thus has all the technical effects of the above sealing assembly, which will not be elaborated herein again.
