[0030] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The embodiment of the present application provides an opening and closing assembly 10 for a storage device. Please refer to Figures 1 to 3 , Figure 1 This is a structural diagram of an embodiment of the opening and closing assembly of the present application; Figure 2 yes Figure 1 A schematic cross-sectional view of the opening and closing member of the opening and closing assembly when the opening and closing member is in a closed position; Figure 3 yes Figure 1 A schematic diagram of the structure of the elastic member of the opening and closing assembly is shown. The opening and closing assembly 10 includes an opening and closing member 110, a fixing member 120, and an elastic member 130. The opening and closing member 110 is rotatably connected to the fixing member 120, and the opening and closing member 110 can rotate between a closed position for closing the storage device and an open position for opening the storage device. The opening and closing member 110 has a first connecting portion 1111, and the elastic member 130 has a first end 131 and a second end 132. The first end 131 is connected to the fixing member 120, and the second end 132 is connected to the first connecting portion 1111. The first connecting portion 1111 can move relative to the first end 131 under the elastic force of the elastic member 130 to rotate the opening and closing member 110 toward the closed position or the open position.

[0032] Optionally, the opening and closing assembly 10 further includes a rotating shaft 140, and the opening and closing member 110 is rotatably connected to the fixing member 120 via the rotating shaft 140. The first connecting portion 1111 of the opening and closing member 110 is located on a side of the rotating shaft 140 close to the first end 131. The opening and closing member 110 can be rotated to a balanced position. When the second end 132 is located on the connecting line 30 between the rotating shaft 140 and the first end 131, and the second end 132 is located between the rotating shaft 140 and the first end 131, the opening and closing member 110 is in the balanced position, and the elastic When the second end 132 is on one side of the connection line 30, the first connection portion 1111 can be moved away from the first end 131 under the elastic force of the elastic member 130, so that the opening and closing member 110 can rotate from the equilibrium position to the closed position. When the second end 132 is on the other side of the connection line 30, the first connection portion 1111 can be moved away from the first end 131 under the elastic force of the elastic member 130, so that the opening and closing member 110 can rotate from the equilibrium position to the open position. The elastic force provided by the elastic member 130 can assist in opening and closing the storage device, making the storage device more convenient to operate.

[0033] Furthermore, the elastic member 130 may be a torsion spring, which has stable elasticity and is not easily deformed or relaxed. The elastic member 130 may be made of a metal alloy with elastic deformation capability, such as stainless steel, titanium alloy, or aluminum alloy. In other embodiments, the elastic member 130 may also be made of plastic with elastic deformation capability.

[0034] Alternatively, in some other embodiments, the elastic member 130 may be a spring, the first end 131 of the elastic member 130 being connected to the fixing member 120, the second end 132 being connected to the first connecting portion 1111, the first connecting portion 1111 of the opening and closing member 110 being located on the side of the rotating shaft 140 away from the first end 131, and when the second end 132 is located on the extension line of the line 30 connecting the rotating shaft 140 and the first end 131, and the rotating shaft 140 is located between the second end 132 and the first end 131, the opening and closing member 110 is in a balanced position, and the elastic member 130 is in a balanced position. It is in the state of maximum elastic deformation, at which time the elastic member 130 is in a stretched state; when the second end 132 is located on one side of the extension line of the connecting line 30, the first connecting portion 1111 can be close to the first end 131 under the elastic force of the elastic member 130, so that the opening and closing member 110 rotates from the equilibrium position toward the closed position; when the second end 132 is located on the other side of the extension line of the connecting line 30, the first connecting portion 1111 can be close to the first end 131 under the elastic force of the elastic member 130, so that the opening and closing member 110 rotates from the equilibrium position toward the open position.

[0035] Optionally, see Figure 4 , Figure 4 yes Figure 1Schematic diagram of the structure of the connecting member of the opening and closing assembly. The opening and closing member 110 includes a first cover plate 112 and a connecting member 111. The first connecting portion 1111 is provided at one end of the connecting member 111 near the fixing member 120. The connecting member 111 also includes a second connecting portion 1112 and a third connecting portion 1113. The third connecting portion 1113 is fixedly connected to the first cover plate 112. The second connecting portion 1112 is located between the first connecting portion 1111 and the third connecting portion 1113. The second connecting portion 1112 is rotatably connected to the fixing member 120.

[0036] Furthermore, the first cover plate 112 and the connector 111 may be separate structures, the first cover plate 112 may be made of plastic, the connector 111 may be made of a metal alloy, and the third connection portion 1113 of the connector 111 may be fixed to the first cover plate 112 by screws. In other embodiments, the first cover plate 112 and the connector 111 may be an integral structure, the first cover plate 112 and the connector 111 may be made of a metal alloy or plastic, and the first cover plate 112 and the connector 111 may be integrally injection molded.

[0037] Optionally, the fixing member 120 includes a second cover plate 121 and a shell 122, the second cover plate 121 is covered on the shell 122, a cavity 1201 is formed between the second cover plate 121 and the shell 122, the elastic member 130 is installed in the cavity 1201, and a fixing bracket 1214 is provided on the side of the second cover plate 121 facing the shell 122, and the first end 131 is connected to the fixing bracket 1214.

[0038] Furthermore, the opening and closing assembly 10 further includes a rotating shaft 140 , and the second connecting portion 1112 is rotatably connected to the fixing member 120 via the rotating shaft 140 .

[0039] Further, please also refer to Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic cross-sectional view of the opening and closing component when the opening and closing member is in a balanced position; Figure 6 yes Figure 1The schematic cross-sectional structure of the opening and closing member of the opening and closing assembly is shown in the open position. When the opening and closing member 110 is in the equilibrium position, the first connecting portion 1111 is located on the line 30 connecting the rotating shaft 140 and the first end 131, and the elastic member 130 is in a state of maximum elastic deformation. At this time, the opening and closing member 110 is subjected to balanced forces, that is, the opening and closing member 110 can remain stationary in the equilibrium position. When the opening and closing member 110 rotates from the equilibrium position toward the closed position or the open position, the elastic deformation of the elastic member 130 decreases. Specifically, when the opening and closing member 110 is in the equilibrium position, the connection between the second end 132 of the elastic member 130 and the first connecting portion 1111 is located on the line 30 connecting the axis of the rotating shaft 140 and the center of the first end 131. The connecting line 30 remains unchanged during the rotation of the opening and closing member 110. When the opening and closing member 110 is in the closed position, the second end 132 is located above the connecting line 30 and on the side of the axis of the rotating shaft 140 close to the fixed bracket 1214. Under the elastic force of the elastic member 130, the second end 132 exerts an upward pressing force on the first connecting portion 1111, causing the first cover plate 112 to be pressed downward. When the opening and closing member 110 rotates to the equilibrium position, the force exerted by the elastic member 130 on the opening and closing member 110 is in a critical state of equilibrium. When the first cover plate 112 is further rotated upward so that the installation axis of the second end 132 exceeds the connecting line 30, the direction of the force exerted by the elastic member 130 immediately changes. Under the action of the elastic force, the first cover plate 112 continues to open to the maximum opening angle and remains in this position, making it convenient for the operator to take items from the storage device. When the first cover 112 needs to be closed, the first cover 112 only needs to be flipped downward. When the installation axis of the second end 132 exceeds the connecting line 30, that is, above the connecting line 30, the first cover 112 can automatically close and press the upper end surface of the storage element 20 of the storage device.

[0040] Furthermore, when the opening and closing member 110 is in the equilibrium position, the direction of the elastic force exerted by the elastic member 130 on the first connecting portion 1111 is directed toward the rotating shaft 140, and at this point, the deformation of the elastic member 130 is at its maximum. When the first cover plate 112 is pressed downward under the action of an external force, causing the opening and closing member 110 to rotate toward the closed position, the first connecting portion 1111 approaches the second cover plate 121. The elastic force exerted by the elastic member 130 on the first connecting portion 1111 is directed toward the side of the rotating shaft 140 closer to the second cover plate 121. Under the action of the elastic force, the first connecting portion 1111 will continue to rotate toward the second cover plate 121, moving the first connecting portion 1111 away from the first end 131, and the elastic deformation of the elastic member 130 will decrease until the opening and closing member 110 remains in the closed position. When the opening and closing member 110 located in the equilibrium position is lifted up to rotate the opening and closing member 110 toward the open position, the first connecting portion 1111 rotates in the direction away from the second cover plate 121, and the elastic force of the elastic member 130 on the first connecting portion 1111 is directed to the side of the rotating shaft 140 away from the second cover plate 121. Under the action of the elastic force, the first connecting portion 1111 will continue to rotate away from the second cover plate 121, so that the first connecting portion 1111 is away from the first end 131, and the elastic deformation of the elastic member 130 is reduced until the opening and closing member 110 remains in the open position.

[0041] Optionally, please also refer to Figures 7 to 9 , Figure 7 yes Figure 1 A schematic structural diagram of the second cover plate of the opening and closing assembly shown; Figure 8 yes Figure 1 A partial structural diagram of the opening and closing assembly shown; Figure 9 yes Figure 1 The second cover plate 121 is provided with a shaft groove 12101 at one end close to the first cover plate 112, and the shaft 140 is clamped in the shaft groove 12101. Figure 4 As shown, the second connecting portion 1112 includes a stop plate 11121 and connecting brackets 11122 located on either side of the stop plate 11121. The connecting brackets 11122 are provided with a rotational axis hole 11102. A rotational axis 140 is inserted through the rotational axis hole 11102, and the opening and closing member 110 is rotatably connected to the fixing member 120 via the rotational axis 140. Specifically, the rotational axis groove 12101 is provided within the cavity 1201, achieving a hidden design for the rotational axis 140, thereby eliminating the visible protrusion structure on the exterior surface of the second cover plate 121.

[0042] Further, see Figure 10 , Figure 10 yes Figure 2An enlarged schematic diagram of a portion of the structure of the opening and closing assembly is shown. The rotating shaft 140 can be snapped into the rotating shaft groove 12101. The cross-section of the rotating shaft groove 12101 can be circular with a notch. The length of the notch is less than the diameter of the rotating shaft 140, and the arc length of the notch is less than half the circumference. The rotating shaft groove 12101 can limit the displacement of the rotating shaft 140, preventing it from disengaging from the rotating shaft groove 12101 during rotation. At the same time, no additional fixing device is required to secure the rotating shaft 140, simplifying the fixing structure of the rotating shaft 140. Specifically, a guide surface 12103 is provided at the notch 12102 of the rotating shaft groove 12101. The guide surface 12103 is in the form of an inclined plane, and the rotating shaft 140 can be snapped into the rotating shaft groove 12101 along the guide surface 12103.

[0043] Furthermore, the rotating shaft 140 can first pass through the rotating shaft hole 11102 and then be snapped into the rotating shaft groove 12101 to achieve rapid assembly of the connecting member 111 and play a role in pre-positioning.

[0044] Furthermore, a connecting hole 11103 is formed on the first connecting portion 1111, and the second end 132 of the elastic member 130 can pass through the connecting hole 11103. Specifically, the second end 132 can rotate relative to the first connecting portion 1111 in the connecting hole 11103.

[0045] Furthermore, the first end 131 of the elastic member 130 can be formed into a ring shape, and a boss 12141 is provided at the end of the fixing bracket 1214 away from the top surface of the second cover plate 121, and the first end 131 can be sleeved on the boss 12141. Specifically, the first end 131 can be limited by a bolt so that the first end 131 can rotate around the boss 12141 but cannot be separated from the boss 12141. This ensures that the elastic force exerted by the elastic member 130 on the first connecting portion 1111 is kept in the direction from the first end 131 to the second end 132. When the opening and closing member 110 deviates from the equilibrium position, the first connecting portion 1111 can be moved away from the first end 131 under the elastic force of the elastic member 130, thereby allowing the opening and closing member 110 to rotate from the equilibrium position toward the open position or the closed position.

[0046] Optionally, a stopper 1211 is provided on the side of the shaft groove 12101 facing away from the fixing bracket 1214 , and a groove 11101 is formed on the connecting member 111 , which is used to avoid the stopper 1211 when the connecting member 111 rotates relative to the second cover plate 121 .

[0047] Optionally, a stop plate 11121 is located at the bottom of the groove 11101. When the stop plate 11121 abuts against the abutting portion 1211 under the elastic force of the elastic member 130, the opening and closing member 110 is located in the open position and remains in the open position under the elastic force. A stop portion 11111 is provided on the side of the first connecting portion 1111 facing away from the stop plate 11121. When the stop portion 11111 abuts against the second cover plate 121 under the elastic force of the elastic member 130, the opening and closing member 110 is located in the closed position and remains in the closed position under the elastic force.

[0048] Furthermore, if Figure 5 As shown, a ridge 1121 is provided on one end of the first cover plate 112 facing the second cover plate 121. When the opening and closing member 110 is in the closed position, the ridge 1121 can contact the stop portion 1211, so that the top surfaces of the first cover plate 112 and the second cover plate 121 form a closed surface. Specifically, the cross-sectional shape of the ridge 1121 can be triangular, and the side of the ridge 1121 facing the stop portion 1211 can be an inclined surface to avoid the stop portion 1211 and prevent the ridge 1121 from abutting the stop portion 1211 during the rotation of the opening and closing member 110.

[0049] Furthermore, protrusions 1216 are provided on both sides of the end of the second cover plate 121 facing the first cover plate 112. The cross-sectional shape of the protrusions 1216 can be triangular. The side of the protrusions 1216 facing away from the fixing bracket 1214 can be an inclined surface. When the opening and closing member 110 is in the closed position, the protrusions 1216 and the inclined surface of the protrusion 1121 come into contact and fit together, forming a closed surface between the side surfaces of the first cover plate 112 and the second cover plate 121, thereby enhancing the aesthetic appearance of the opening and closing assembly 10.

[0050] Optionally, the number of connectors 111 may be one or more, and the number of housings 122 may be consistent with the number of connectors 111. Furthermore, the number of connectors 111 may be two, with the two connectors 111 respectively installed on both sides of the second cover 121. In other embodiments, the number of connectors 111 may also be 3, 4, 6, 8, etc., which will not be described in detail here.

[0051] Furthermore, the number of elastic members 130 can be twice the number of connecting members 111. Each connecting member 111 is provided with two connecting brackets 11122, and the connecting brackets 11122 are respectively connected to the elastic members 130. In other embodiments, the number of elastic members 130 can also be the same as the number of connecting members 111.

[0052] Optionally, a plurality of studs 1213 are provided on the surface of the second cover plate 121 facing the elastic member 130 , and a connecting piece 1221 is provided on the shell 122 . The connecting piece 1221 has screw mounting holes, and the connecting piece 1221 and the studs 1213 can be locked with screws.

[0053] Furthermore, a stud 1213 is provided on the second cover plate 121 near the shaft slot 12101. The housing 122 is fastened to the stud 1213 via screws. The sidewalls of the housing 122 press against the shaft slot 12101 to limit the displacement of the shaft 140 within the shaft slot 12101. The housing 122 can simultaneously retain the shaft 140 while being fixedly connected to the second cover plate 121. Specifically, while the connecting piece 1221 is locked to the stud 1213, the connecting piece 1221 at least partially covers the shaft slot 12101, thereby retaining the shaft 140 and preventing it from disengaging from the shaft slot 12101.
