Referring to fig. 1, fig. 1 is a schematic view of a door mounting structure 100 according to an exemplary embodiment of the present application.

The present application provides a door body mounting structure 100, including a mounting base 10, a door body 20, and a damping assembly 30. The door 20 is movably mounted to the mounting base 10 so as to be openable and closable with respect to the mounting base 10. The door 20 may be movable relative to the mounting base 10 in a manner that includes, but is not limited to, sliding and rotating. The damper assembly 30 is used to apply a damping force to the door body 20 in an open state, so that the door body 20 is maintained in an open position. Therefore, after the door 20 is opened, the damping assembly 30 can provide resistance to the door 20, so that the door 20 is prevented from being opened further, and the door 20 is prevented from being closed by itself without being held by hand.

The specific embodiment of the damping assembly 30 is not limited. In one embodiment, a friction member may be provided between the door 20 and the mounting base 10 to be relatively rubbed, and after the door 20 is opened, friction of the friction member is damped to maintain the door 20 in the opened position.

Referring to fig. 2, fig. 2 is an enlarged view of a portion a in fig. 1.

In one embodiment, the damper assembly 30 includes a damper 31 and a mating member 32, and the damper 31 includes a housing and a damper body (not shown) having a predetermined viscosity enclosed in the housing. The mating member 32 includes an outer end 320 disposed on the outside of the housing and an inner end (not shown) disposed within the damping body, the adhesive force applied to the inner end by the damping body acting on the opened door body 20 through the outer end 320 to maintain the door body 20 in the opened position. In this embodiment, the viscosity of the damper body is used to provide resistance to the door body 20, so that the hard impact applied to the door body 20 by the outer end 320 can be alleviated, and the service life of the damper assembly 30 is long. The damping body comprises but is not limited to silicone oil, castor oil and mechanical oil, and the viscosity of the damping body can be customized according to actual requirements. In a practical application scenario, the damper 31 is fixed to the mounting base 10, and the outer end 320 of the fitting member 32 is used for positioning and fitting the door body 20 when the door body 20 is opened, so that the door body 20 is kept in the open position.

In one embodiment, the mating element 32 may remain relatively fixed with the damper 31. That is, the inner end of the engaging member 32 is immovable in the damper, for example, the inner end of the engaging member 32 is adhered by the damper, the outer end 320 is a free end, and the outer end 320 is adapted to be in positioning engagement with the opened door 20, so that the door 20 can be held at a certain opened position.

In this embodiment, the door 20 may be held in a plurality of open positions. Specifically, the matching piece 32 and the damper 31 may move relatively, and the door body 20 may be opened to drive the matching piece 32 to follow up, where the adhesion force of the damping body acting on the inner end is smaller than the force transferred to the damping body when the door body 20 is driven to open by an external force, and is greater than the force transferred to the damping body by the door body 20 when the external force is removed. That is, when the door body 20 is opened by an external force, the external driving force can overcome the adhesion force of the damping body to the inner end, so that the inner end can move inside the damping body following the door body 20. When the external force is removed, the adhesion force of the damping body to the inner end forms resistance to the movement of the inner end, and is transmitted to the door body 20, so that the door body 20 is kept at the front opening position. By the arrangement, the door body 20 can hover through the adhesion force of the damping body at a plurality of opening positions, so that the door body 20 can hover more flexibly and the positions are more diversified. For example, the door 20 may hover at an arbitrary angle after being opened, but is not limited thereto.

In an actual application scenario, the damper 31 may be mounted to the mounting base 10, and the outer end 320 is mounted to the door 20. Alternatively, the damper 31 may be mounted to the door body 20, and the corresponding outer end 320 mounted to the mounting base 10.

Referring to fig. 3-5, fig. 3 is a schematic diagram of the transmission assembly 40. Fig. 4 is a schematic view of the damper 31 mounted to the mounting base 10. Fig. 5 is a schematic view of a partial structure of the door body 20.

In one embodiment, the door mounting structure 100 further includes a transmission assembly 40, and the damper 31 is mounted to the mounting base 10 and is fixed relative to the mounting base 10. The engaging member 32 is movable with respect to the damper 31, and an external force for opening the door body 20 is transmitted to the engaging member 32 through the transmission assembly 40. By arranging the transmission assembly 40 in this way, the physical connection between the door body 20 and the mating member 32 is realized, and the reliable transmission of power between the door body 20 and the mating member 32 is realized.

The specific embodiment of the transmission assembly 40 is not limited, and the transmission assembly 40 may be different according to the movable connection manner of the door body 20 and the mounting base body 10. The door body 20 is slidably or rotatably connected to the mounting base 10.

In the embodiment shown in fig. 3, the door body 20 is rotatably mounted on the mounting base 10, the mating member 32 is rotatable relative to the damper 31, the transmission assembly 40 includes a driving member 41 and a driven member 42 that are rotatable, and the driving member 41 is disposed on the door body 20 and can rotate coaxially with the door body 20. Specifically, the door body 20 includes a rotating shaft 21, the installation base 10 is provided with a rotating shaft hole 11, and the rotating shaft 21 is rotatably disposed in the rotating shaft hole 11. The rotating shaft 21 is connected to the axis of the driving member 41 and is fixed relative to the rotating shaft 21. The mating member 32 is connected to the axis of the driven member 42, that is, the outer end 320 of the mating member 32 is connected to the axis of the driven member 42, and the driving member 41 is in driving connection with the driven member 42, so that power transmission is realized. In this embodiment, the door body 20 is rotatably connected to the mounting base 10, so that the door body 20 can be opened and closed more conveniently. Moreover, the driving member 41 and the driven member 42 are both rotating members, which is beneficial to saving the movable space and improving the structural compactness.
