[0031] The utility model provides a door body structure.

[0032] In the embodiment of the present utility model, the door structure is as follows Figures 1 to 5As shown, it includes a door frame 100, a door body 200 and a first damping member 300. The door frame 100 has an installation position 110, and the door body 200 is arranged at the installation position 110. The door body 200 is rotatably connected to the door frame 100 to have a rotation axis 210. The rotation axis 210 passes through the first damping member 300. The first damping member 300 and the door body 200 are interference fit in the extension direction of the rotation axis 210, that is, the first damping member 300 is squeezed in the extension direction of the rotation axis 210. The first damping member 300 has a friction force on the rotating door body 200, so that the door body 200 has a damping feeling during the rotation process, so as to slow down the rotation speed of the door body 200 relative to the door frame 100. Therefore, when the door body 200 rotates to the extreme opening and closing position, the impact force that stops the door body 200 from rotating is smaller, so that the door body 200 structure can have a longer service life. And because the first damping member 300 is relatively fixed to the door frame 100, that is, the first damping member 300 will not move relative to the door frame 100, it can be inferred that the first damping member 300 is squeezed by the door body 200 at the rotation axis 210, so that no matter to which angle the door body 200 rotates relative to the door frame 100, the door body 200 will be subject to the friction force provided by the first damping member 300, that is, the door body 200 will have a damping feeling during the process of rotating to any angle, and because the first damping member 300 is only arranged at the rotation axis 210, the volume of the first damping member 300 is relatively small, and less material is required to produce the first damping member 300, which helps to reduce production costs.

[0033] Optionally, in the extension direction of the rotation axis 210, the first damping member 300 is disposed between the door frame 100 and the door body 200, and the first damping member 300 is also interference-fitted with the door frame 100 in the extension direction of the rotation axis 210. That is, the first damping member 300 is squeezed by the door frame 100 and the door body 200, and deforms along the extension direction of the rotation axis 210, and provides friction to the door body 200. In other embodiments, the door body 200 and other structures may co-extrude the first damping member 300.

[0034] Optionally, there are multiple mounting positions 110, and there are multiple door bodies 200. One door body 200 is rotatably connected to one mounting position 110, and multiple mounting positions 110 are arranged in sequence in the extension direction of the rotation axis 210. That is, multiple door bodies 200 rotate around the same rotation axis 210. The door body 200 structure also includes a first rotating shaft 500 having a rotation axis 210, and a first rotating shaft 500 is correspondingly penetrated between two adjacent door bodies 200. This design can reduce the amount of rotating shafts used, and helps to simplify the installation structure of the door frame 100 and the door body 200, so that the door body 200 and the door frame 100 are easy to assemble. In other embodiments, multiple mounting positions 110 can also be arranged in other directions. In another embodiment, it can also be that a first rotating shaft 500 is only penetrated by a door body 200 and a door frame 100.

[0035] Optionally, the door body 200 structure further includes a second damping member 400 for the first rotating shaft 500 to pass through, the first damping member 300 and the second damping member 400 are respectively arranged on opposite sides of the door body 200 in the extension direction of the rotation axis 210, a plurality of first damping members 300 are provided, a plurality of second damping members 400 are provided, and one door body 200 corresponds to one second damping member 400 in the extension direction of the rotation axis 210. That is, one first rotating shaft 500 can pass through two second damping members 400, and the second damping member 400 is pressed by the door body 200 on the first rotating shaft 500, and provides friction force for the door body 200, so that when the door body 200 rotates around the first rotating shaft 500, the second damping member 400 cooperates with the first damping member 300, and the damping feeling of the door body 200 is enhanced. In other embodiments, the second damping member 400 may also be not provided.

[0036] Optionally, the door body 200 structure further includes a second rotating shaft 600 having a rotation axis 210, the second rotating shaft 600 is provided on the door body 200 and is located on a side opposite to the first rotating shaft 500, and the second rotating shaft 600 passes through the first damping member 300. That is, the first rotating shaft 500 and the second rotating shaft 600 jointly connect the door body 200 to the door frame 100, and the first damping member 300 is squeezed by the door frame 100 and the door body 200 on the second rotating shaft 600. In other embodiments, the first rotating shaft 500 and the second rotating shaft 600 may also be of the same structure, that is, one rotating shaft passes through opposite sides of the door body 200.

[0037] Optionally, the door body 200 is provided with an avoidance cavity 220, the avoidance cavity 220 is provided with a first cavity wall 230, the first rotating shaft 500 is penetrated through the first cavity walls 230 of two adjacent door bodies 200, and the two ends of the first rotating shaft 500 extend into the corresponding avoidance cavity 220 respectively, and the second damping member 400 includes a damping member body 410 penetrated through the first cavity wall 230, and a first abutting portion 420 provided at one end of the damping member body 410, and a first abutting portion 420 provided at the other end of the damping member body. The first abutment portion 420 and the second abutment portion 430 limit a limiting ring groove 440 for the first cavity wall 230 to be inserted into. The second abutment portion 430 is arranged between the door body 200 and the door frame 100. The first abutment portion 420 is interference-fitted with the first cavity wall 230 in the extending direction of the rotation axis 210, and the second abutment portion 430 is interference-fitted with the first cavity wall 230 and the door frame 100 in the extending direction of the rotation axis 210. That is, the first abutment portion 420 and the second abutment portion 430 cooperate with each other, so that during the rotation of the door body 200, both sides of the first cavity wall 230 are evenly subjected to friction, and in long-term use, the first abutment portion 420 and the second abutment portion 430 can evenly share the wear and tear, so that the service life of the second damping member 400 is extended. In other embodiments, the second damping member 400 can also include one of the first abutment portion 420 and the second abutment portion 430.

[0038] Optionally, a limiting portion 510 is provided at one end of the first rotating shaft 500, which is opposite to the first abutting portion 420 in the direction of the rotating axis 210, and an elastic clamping member 520 is clamped at the other end, and the clamping member is arranged opposite to the second abutting portion 430. Since the first abutting portion 420 will be squeezed to generate friction force on the door body 200, the limiting portion 510 and the elastic clamping member are respectively provided at both ends of the first rotating shaft 500 to respectively abut against the first abutting portions 420 of the two second damping members 400 on the first rotating shaft 500. At the same time, the first abutting portion 420 can also prevent the limiting portion 510 or the elastic clamping member 520 from rubbing against the door body 200, so as to prevent noise from being generated during the rotation of the door body 200. The first rotating shaft 500 and the limiting portion 510 are integrally formed. During the installation process, after the end of the first rotating shaft 500 without the limiting portion 510 passes through a second damping member 400, a first cavity wall 230, the door frame 100, another first cavity wall 230 and another second damping member 400 in sequence, the elastic clamping member 520 is clamped with the end of the first rotating shaft 500 without the limiting portion 510. In other embodiments, both ends of the first rotating shaft 500 may have the elastic clamping member 520, that is, both ends of the first rotating shaft 500 press the second damping member 400 through the elastic clamping member 520.

[0039] Optionally, the first abutting portion 420 and the second abutting portion 430 are arranged to be gradually contracted in the direction away from each other. This makes the contact area between the limiting portion 510, the elastic clamping member 520 and the door frame 100 and the second damping member 400 limited, and makes the first abutting portion 420 and the second abutting portion 430, when squeezed, have fewer structures that are squeezed out and can hinder the rotation of the door body 200, that is, this design makes the second damping member 400 not affect the rotation of the door body 200 when squeezed. In other embodiments, the first abutting portion 420 and the second abutting portion 430 may not have a structure that is gradually contracted in the direction away from each other.

[0040] Optionally, the first damper 300 and the second damper 400 have a compression amount in the extension direction of the rotation axis 210, and the value range of the compression amount is within 0.3mm to 1mm. The first damper 300 and the second damper 400 both have a compression state and a natural state. The natural state is a state in which the first damper 300 or the second damper 400 is not squeezed by the door body 200, that is, a state in which the first damper 300 and the second damper 400 are not installed on the door body 200 and the door frame 100. The compression state is a state in which the first damper 300 or the second damper 400 is squeezed by the door body 200 and deformed, that is, a state after the first damper 300 or the second damper 400 is installed on the door body 200 and the door frame 100. In the process of the first damper 300 and the second damper 400 changing from the natural state to the compressed state, the first damper 300 and the second damper 400 will be deformed along the extension direction of the rotation axis 210, that is, the first damper 300 and the second damper 400 will be compressed in the extension direction of the rotation axis 210, and the compression amount is in the range of 0.3mm to 1mm. Within this range, the pressure of the door body 200 on the first damper 300 and the second damper 400 is appropriate, so that the first damper 300 and the second damper 400 have a large friction force on the door body 200 as a damping feeling when the door body 200 rotates, and the door body 200 will not generate excessive pressure on the first damper 300 and the second damper 400, so that the first damper 300 and the second damper 400 have excessive friction on the door body 200, thereby hindering the rotation of the door body 200.

[0041] Optionally, the first damper 300 and the second damper 400 are made of silicone. Silicone has a certain elasticity, so that after the door body 200 and the first damper 300 and the second damper 400 are squeezed, even if the first damper 300 and the second damper 400 are worn during long-term use, the elasticity of silicone can make the first damper 300 and the second damper 400 abut against the door body 200, and the friction coefficient of silicone is large, so it can still provide sufficient friction to the door body 200 when the contact area is small. In other embodiments, the first damper 300 and the second damper 400 can also be made of damping metal.

[0042] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
