[0021] Please refer to Figures 1 to 3 , the structure of the invisible door provided by the utility model will be described. The invisible door structure comprises a door pocket 20 for covering the door opening 10 and a door frame 40 for covering the edge of the door panel 30; the door pocket 20 has a stepped wall surface 200 that conforms to the inner wall of the door opening 10, the stepped wall surface 200 has a bent inner corner 201 and a bent outer corner 202 formed by continuous bending, the bent inner corner 201 is provided with a sealing strip 50, and the bent outer corner 202 is provided with a magnetic strip 60; the door frame 40 has a first matching surface 41 and a second matching surface 42, and the inside of the door frame 40 is provided with a magnetic tab 70 corresponding to the position of the first matching surface 41; wherein the first matching surface 41 is used to press against the magnetic strip 60 when the door panel 30 is closed and to adsorb the magnetic strip 60 through the magnetic tab 70, and the second matching surface 42 is used to press against the sealing strip 50 when the door panel 30 is closed.
[0022] It should be noted that, considering the characteristics of the invisible door, the door pocket 20 in the embodiment can adopt the same material and texture as the indoor wall decorative plate. Since the invisible door needs to be embeddedly installed to avoid external convexity, the inner wall of the door opening 10 should be provided with a notch for the door plate 30 to be embedded. Thus, the part where the door pocket 20 and the inner wall of the door opening 10 conform to each other is formed as the stepped wall surface 200. It should be explained here that the stepped wall surface 200 has a common corner wall based on the continuous bending of the bending inner corner 201 and the bending outer corner 202, that is, one corner wall of the bending inner corner 201 is also a corner wall of the bending outer corner 202, and the sealing strip 50 and the magnetic strip 60 are respectively attached to the two corner walls of the bending outer corner 202, while the sealing strip 50 is located at the bending inner corner 201. Therefore, the sealing strip 50 is connected to the common corner wall of the bending inner corner 201 and the bending outer corner 202, and the magnetic strip 60 is attached to the other corner wall of the bending outer corner 202. Based on the structure of the door pocket 20, the structure of the door frame 40 should match it, that is, the first matching surface 41 and the second matching surface 42 are actually also formed in a stepped shape matching the continuous bending part of the stepped wall surface 200.
[0023] The invisible door structure provided in the embodiment, compared with the prior art, when the door plate 30 is closed, the door frame 40 cooperates with the bending inner corner 201 and the bending outer corner 202 formed by the continuous bending of the stepped wall surface 200. The magnetic strip 60 on the bending outer corner 202 cooperates with the first matching surface 41 to enable the magnetic sheet 70 inside the door frame 40 to be attracted to the magnetic strip 60, thereby improving the stability of the closed door plate 30. At the same time, the second matching surface 42 can press the sealing strip 50 on the bending inner corner 201. Not only can the sealing strip 50 provide a buffering effect to avoid the closed door plate 30 from making a collision sound and improve the quietness, but also can improve the sealing performance after the door plate 30 is closed.
[0024] In some embodiments, referring to Figure 2 and Figure 3 , the first matching surface 41 is an inclined surface inclined relative to the door plate 30, the second matching surface 42 is parallel to the door plate 30, the second matching surface 42 and the first matching surface 41 are connected through the third matching surface 43, and the third matching surface 43 is perpendicular to the door plate 30 and used to press the sealing strip 50 when the door plate 30 is closed.
[0025] The first matching surface 41 is a slope surface, which can increase the contact area with the magnetic strip 60, thereby improving the adsorption stability and tightness of the magnetic sheet 70 and the magnetic strip 60. In addition, the slope surface can have a certain dislocation freedom between the magnetic strip 60 and the door plate 30 when the door plate 30 is closed, thereby avoiding the influence of the support of the magnetic strip 60 on the first matching surface 41 on the compression tightness of the sealing strip 50 by the second matching surface 42 when the door plate 30 is closed, thereby ensuring the sealing effect. On this basis, the third matching surface 43 between the first matching surface 41 and the second matching surface 42 can also abut against the side wall of the sealing strip 50 towards the inside of the hole to form a seal, thereby further improving the sealing effect.
[0026] It should be noted that, as shown in Figure 3 , the door frame 40 has a cavity 44, and the two adjacent cavity walls of the cavity 44 form the first matching surface 41 and the third matching surface 43, respectively. The magnetic sheet 70 is arranged in the cavity 44 and is attached to the first matching surface 41. The door frame 40 can be a pultruded aluminum profile, and the cavity walls of the cavity 44 on one side of the door frame 40 form the first matching surface 41 and the third matching surface 43, and the magnetic sheet 70 can be hidden in the cavity 44, thereby improving the installation stability of the magnetic sheet 70 and avoiding the exposure of the magnetic sheet 70 to affect the appearance and texture of the door plate 30 after opening.
[0027] In order to improve the connection stability and disassembly convenience of the magnetic sheet 70 in the cavity 44, as shown in Figure 2 and Figure 3 , the two opposite cavity walls of the cavity 44 are respectively provided with a clamping rib 45, and the clamping rib 45 and the first matching surface 41 form a clamping groove 46 suitable for the magnetic sheet 70 to be inserted. The magnetic sheet 70 can be directly inserted into the clamping groove 46 inside the cavity 44 from one end of the door frame 40, and the two clamping ribs 45 and the first matching surface 41 cooperate to constrain the two side edges of the magnetic sheet 70, which is not only convenient to disassemble, but also simple in structure.
[0028] As a specific embodiment of the sealing strip 50, please refer to Figure 2 and Figure 3 , the sealing strip 50 comprises a main body part 51 and a first plug-in part 52; the two adjacent side walls of the main body part 51 are respectively attached to the two corner walls of the bent inner corner 201, and the first plug-in part 52 is integrally formed on the main body part 51; wherein one of the corner walls of the bent inner corner 201 is provided with a first insertion groove 203, and the first plug-in part 52 is fixedly plugged into the first insertion groove 203.
[0029] The sealing strip 50 can be a rubber strip with equal cross-section extension. The abutment of the body part 51 with the two corner walls of the bent inner corner 201 can ensure the stability of the connection. When the door panel 30 is closed, the two corner walls of the bent inner corner 201 can provide support force to the body part 51, so that the second and third matching surfaces 42 and 43 can press the two adjacent wall surfaces of the body part 51 respectively, thereby improving the sealing effect and ensuring the quietness based on the flexible buffering. The first insertion part 52 can be a sheet structure with barb structure on both sides. When installed, the first insertion part 52 can be slid into the end of the first insertion slot 203. This not only facilitates assembly, but also improves the stability of the connection by using the pressing action of the barb structure on the slot wall of the first insertion slot 203.
[0030] In some possible implementation manners, please refer to Figure 3 The side middle part of the body part 51 has a buffer groove. The body part 51 forms a first sealing edge 511 and a second sealing edge 512 on the two sides of the buffer groove. The middle part of the first sealing edge 511 is provided with the first insertion part 52. The second sealing edge 512 is used to abut against the second matching surface 42. The side wall of the body part 51 away from the slot opening of the buffer groove is used to abut against the third matching surface 43.
[0031] The buffer groove can improve the buffering effect of the body part 51 on the second matching surface 42 when the door panel 30 is closed, thereby ensuring the quietness when closing the door. In addition, the buffer groove can also improve the tightness between the body part 51 and the second matching surface 42, thereby improving the sealing effect when the door panel 30 is closed. In addition, after the door panel 30 is closed, the third matching surface 43 presses against the side wall of the body part 51 away from the slot opening of the buffer groove, thereby increasing the sealing contact area between the door frame 40 and the sealing strip 50, and further ensuring the sealing effect.
[0032] It should be understood that, in the embodiment, as shown in Figure 2 The door stop 80 is arranged near the bent outer corner 202. The side wall of the door stop 80 facing the bent outer corner 202 is connected with the magnetic strip 60. The door stop 80 can block the position of the door panel 30 when the door panel 30 is closed, thereby avoiding over-closing of the door panel 30. In addition, the magnetic strip 60 is arranged on the door stop 80, thereby avoiding direct collision between the edge of the door panel 30 and the door stop 80, and affecting the quietness.
[0033] As a specific embodiment of the magnetic strip 60, please refer to Figure 2 and Figure 3 The magnetic strip 60 includes a flexible buffer body 61 and a magnetic plate 62 embedded in the flexible buffer body 61. The flexible buffer body 61 has an adsorption surface 611 for abutting against the first matching surface 41. The magnetic plate 62 is parallel to the adsorption surface 611 and can adsorb the magnetic piece 70 when the door panel 30 is closed.
[0034] The flexible buffer body 61 can be a flexible rubber body, capable of buffering and contact sealing the first fitting surface 41. The magnetic plate 62 is embedded in the flexible buffer body 61 along the extension direction of the flexible buffer body 61. The magnetic plate 62 is used to adsorb the magnetic attraction piece 70, thereby improving the stability of the door plate 30 in the closed state. In addition, the magnetic plate 62 can also serve as a support framework of the flexible buffer body 61, thereby ensuring the supportability of the flexible buffer body 61.
[0035] Figure 3 An optional installation mode of the magnetic attraction strip 60 is shown in FIG. 8. The side wall of the door stopper 80 is provided with a second insertion slot 81, and the flexible buffer body 61 is integrally formed with a second insertion part 63. The second insertion part 63 is inserted into the second insertion slot 81. The second insertion part 63 can also be a sheet type with barbs on both sides. When installed, the second insertion part 63 is inserted into the end of the second insertion slot 81. The installation is convenient, and the connection is stable and reliable.
[0036] In some embodiments, referring to FIGS. 9 and 10, the door frame 40 is provided with a buckle edge 47 on both sides for buckling the edge of the door plate 30. Figure 1 Figure 2 The buckle edge 47 can be used to decorate the edge of the door plate 30, thereby improving the texture of the edge of the door plate 30 and the connection stability between the door frame 40 and the door plate 30.
[0037] The above description is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
