As shown in fig. 1 to 5, a first aspect of the present invention provides a door assembly, which includes a door frame 100, a door body 102, and a limiting mechanism 104; the door body 102 is hinged to the door frame 100 and is suitable for being switched between an opening position and a closing position; the limiting mechanism 104 comprises a flexible limiting member 106 and a limiting groove 108 which are suitable for clamping fit, one of the flexible limiting member 106 and the limiting groove 108 is arranged on the door frame 100, and the other is arranged on the door body 102; in the closed position, the flexible limiting member 106 is engaged with the limiting groove 108, and in the open position, the flexible limiting member 106 is separated from the limiting groove 108.
According to the utility model discloses the door subassembly that the embodiment of first aspect provided, set up flexible locating part 106 through one in door frame 100 and the door body 102, another in door frame 100 and the door body 102 sets up spacing groove 108, when making the door body 102 be in closed position, flexible locating part 106 can cooperate with spacing groove 108 mutual joint, and then can undertake the partial atress of the door body 102 and door frame 100 articulated position department, the life of the door body 102 and door frame 100 articulated position department has been prolonged, the condition of the unable closing of the door body 102 of having avoided leading to because door body 102 warp takes place. Meanwhile, by using the flexible limiting piece 106, the impact force between the door body 102 and the door frame 100 when the door body 102 is switched from the opening position to the closing position can be reduced, so that the impact deformation of the door body 102 and the door frame 100 is avoided, and the noise generated by the impact between the door body 102 and the door frame 100 when the door body 102 is closed can be reduced.
Referring to fig. 1 to 5, in the embodiment of the present invention, the door frame 100 is used for installing a door body 102, and correspondingly, the door frame 100 includes a first upright 110, a second upright 112 and a pair of cross beams, which are oppositely disposed, so that the pair of cross beams, the first upright 110 and the second upright 112 are sequentially spliced to form the door frame 100. The door frame 100 may be made of an aluminum alloy material, so that the door frame 100 may have a certain structural strength, and the weight of the door frame 100 may be reduced.
The door 102 is hinged to the door frame 100, and in order to ensure the hinge stability of the door 102 and the door frame 100, two sets of hinges may be disposed between the door frame 100 and the door 102 to achieve the above purpose. As described above, the door body 102 may be hinged to the first pillar 110, and the door body 102 may be switched between the open position and the closed position with respect to the door frame 100.
The limiting mechanism 104 is used for limiting the movement of the door body 102, and it can be understood that when the door body 102 is at the closing position, the limiting mechanism 104 limits the movement of the door body 102, so that the door body 102 can be centered with the door frame 100, and the accuracy of the movement of the door body 102 to the closing position is ensured. On the other hand, the limiting mechanism 104 can bear part of the stress at the hinge position of the door body 102 and the door frame 100 when the door body 102 is at the closing position, and it can be understood that when the door body 102 is at the closing position, the bearing between the door body 102 and the door frame 100 can be realized through the hinge and the limiting mechanism 104, so that the stress between the door body 102 and the door frame 100 can be reduced, and the service life of the hinge between the door body 102 and the door frame 100 is ensured. By such an arrangement, the occurrence of situations such as the door 102 being not closed in place due to the deformation of the hinge can be reduced.
In the embodiment of the present invention, the limiting mechanism 104 includes a flexible limiting part 106 and a limiting groove 108 which are engaged with each other, and when the door 102 is in the closed position, the flexible limiting part 106 can be engaged with the limiting groove 108, thereby achieving the above-mentioned purpose. Meanwhile, through the arrangement of the flexible limiting piece 106, the impact of the door body 102 on the door frame 100 caused by the switching process from the opening position to the closing position can be reduced, the impact force of the door body 102 on the door frame 100 can be further reduced, the structural stability of the door body 102 and the door frame 100 is further ensured, the possibility of deformation of the door body 102 and the door frame 100 is reduced, and the noise generated by collision between the door body 102 and the door frame 100 when the door body 102 is closed can also be reduced. The flexible stopper 106 mentioned here can be made of a material having a certain deformation ability, such as rubber.
In the embodiment of the present invention, the flexible limiting member 106 may be disposed on one of the door frame 100 and the door body 102, and the limiting groove 108 may be disposed on the other of the door frame 100 and the door body 102. For example, the flexible retaining member 106 may be disposed on the door frame 100, and the retaining groove 108 may be disposed on the door body 102. Alternatively, the flexible limiting member 106 may be disposed on the door body 102, and the limiting groove 108 may be disposed on the door frame 100.
The above arrangement is exemplified by the flexible retaining member 106 and the retaining groove 108 being one.
