DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0032] The utility model relates to a backplane lifting structure, which includes a base plate 100, a storage module 200 and a locking mechanism 300.

[0033] As Figure 1 , Figure 2 and Figure 3 shown, the base plate 100 can be set as a flat plate structure and is placed vertically. The storage module 200 is installed on the base plate 100 and can be lifted relative to the base plate 100. The storage module 200 can be structures such as a frame body, a plate body, a box body, etc. The storage module 200 and the base plate 100 can be slidably connected through a guiding structure such as a track. The locking mechanism 300 is installed on the base plate 100. The locking mechanism 300 can be set to one or two, etc. The locking mechanism 300 is located on the rising path of the storage module 200. When the storage module 200 rises to a certain position, the locking mechanism 300 can lock and fix the storage module 200 at the current height. Specifically, the locking mechanism 300 includes a locking member 310, an elastic member 320 and a limiting member 330. Both the locking member 310 and the limiting member 330 can rotate relative to the base plate 100. When the locking member 310 rotates, it has a first position and a second position. When the limiting member 330 rotates, it has a third position and a fourth position. As Figure 4 shown, in the illustrated direction, when the locking member 310 rotates counterclockwise, it rotates from the second position to the first position. As Figure 5 shown, when the locking member 310 rotates clockwise, it rotates from the first position to the second position. When the locking member 310 rotates to the first position, it is used to lock the storage module 200 at the current height position. After the locking member 310 disengages from the first position, the locking of the storage module 200 is released, and other positions deviating from the first position are all second positions. The elastic member 320 can be selected from elastic components such as a spring and a torsion spring. The elastic member 320 exerts an elastic acting force on the locking member 310, and this elastic acting force drives the locking member 310 to rotate to the first position. When the limiting member 330 rotates clockwise, it rotates from the fourth position to the third position, and when the limiting member 330 rotates counterclockwise, it rotates from the third position to the fourth position. When the base plate 100 rotates from the second position to the first position, it can abut against the limiting member 330 and drive the limiting member 330 to rotate from the fourth position to the third position. When the limiting member 330 rotates to the third position, the limiting member 330 can position the locking member 310 at the first position.

[0034] Under normal conditions, as Figure 4 shown, the locking member 310 is kept at the first position under the elastic acting force of the elastic member 320. The storage module 200 rises on the base, as Figure 5As shown in the figure, during the ascending process, the storage module 200 can push the locking member 310 to rotate from the first position to the second position. After the storage module 200 continues to ascend and passes over the locking member 310, the locking member 310 resets to the first position under the elastic force of the elastic member 320. The locking member 310 is clamped on the storage module 200 to lock the storage module 200 at the current height position. The locking member 310 also serves as the support for the storage module 200 at the current height, which is equivalent to the storage module 200 hanging on the locking member 310. The locking member 310 pushes the limiting member 330 to rotate and be positioned at the third position. The limiting member 330 at the third position can limit the locking member 310 from continuing to rotate counterclockwise at the first position, that is, the specific position of the first position of the locking member 310 is defined by the limiting member 330. When it is necessary to pull the storage module 200 downward for use, only a certain downward pulling force needs to be applied to the storage module 200 by hand. The pulling force overcomes the torsion formed by the elastic member 320 on the locking member 310, and the storage module 200 pushes the locking member 310 from the first position to the second position. The locking member 310 disengages from the clamping of the storage module 200, and at this time, the storage module 200 can be pulled downward. At this time, the limiting member 330 can rotate freely between the third position and the fourth position. After the storage module 200 completely disengages from the locking member 310, the locking member 310 resets to the first position under the elastic force of the elastic member 320, and then drives the limiting member 330 to reset to the third position. At this time, the limiting member 330 positions the locking member 310 at the first position, which is convenient for the storage module 200 to be re-aligned with the locking member 310 when ascending. The use of the storage module 200 only requires directly dragging it, and neither locking nor pulling requires direct operation of the locking mechanism 300 by hand, with a simple structure and convenient use.

[0035] The present utility model also relates to a cabinet that applies this backplane lifting structure. The base plate 100 can be used as one of the side plates or cabinet doors of the cabinet and other components. The cabinet can be, but is not limited to, a kitchen cabinet, a mirror cabinet, a bathroom cabinet, etc. The storage module 200 can be used to place various items such as towels and clothes. During use, only the storage module 200 needs to be pulled downward to be used. After the storage module 200 is lifted upward and fixed by the locking mechanism 300, the storage module 200 can be hidden in the cabinet, which is very convenient to use.

[0036] Among them, the locking member 310 and the limiting member 330 can be directly installed on the base. In some specific embodiments of the present utility model, such as Figure 3 , Figure 4 and Figure 5As shown, the locking mechanism 300 further includes a housing 340. The housing 340 can be fixedly installed on the substrate 100 by means such as screws, snap connections, or gluing. Both the locking member 310 and the limiting member 330 can be rotatably installed on the housing 340 through a rotating shaft. The rotating shafts of the locking member 310 and the limiting member 330 can be arranged parallel to each other. The elastic member 320 can also be installed in the housing 340, and the housing 340 is used as a support to apply an elastic acting force to the locking member 310. The housing 340 facilitates the fixed installation of the locking mechanism 300 at different positions on the substrate 100 for use in cooperation with the storage module 200.

[0037] Among them, as Figure 4 and Figure 5 shown, a limiting groove 341 is provided on the housing 340. The limiting groove 341 can be opened at the bottom of the housing 340. One end of the limiting member 330 passes through the limiting groove 341, and the end of the limiting member 330 can extend out of the housing 340 through the limiting groove 341. When the limiting member 330 rotates, one end of the limiting member 330 slides along the limiting groove 341, and the limiting groove 341 can limit the yaw of the limiting member 330 in the axial direction of the rotating shaft during rotation. When the limiting member 330 rotates to the third position, the limiting member 330 abuts against one end of the limiting groove 341, thereby positioning the third position of the limiting member 330.

[0038] Furthermore, the limiting member 330 can be in a block shape, a plate shape, etc. In this embodiment, the limiting member 330 is in a rod shape. As Figure 4 and Figure 5 shown, the limiting member 330 includes a first rod section 331, a second rod section 332, and a third rod section 333. The first rod section 331 can be a straight rod or a bent rod, etc. The second rod section 332 and the third rod section 333 extend from both ends of the first rod section 331 in the same direction. The first rod section 331, the second rod section 332, and the third rod section 333 are distributed in a U shape. The second rod section 332 and the third rod section 333 are straight rods. The length of the second rod section 332 is greater than the length of the third rod section 333. The first rod section 331 and the housing 340 can be rotatably connected through a rotating shaft. The end of the second rod section 332 passes through the limiting groove 341, and the end of the third rod section 333 faces the locking member 310. When the locking member 310 rotates to the first position, the end of the third rod section 333 abuts against the locking member 310.

[0039] In some specific embodiments of the present invention, as Figure 3 and Figure 4As shown, the locking member 310 is a rod structure. The locking member 310 can be set to an L-shaped bend. One end of the locking member 310 is provided with a hook portion 311. The hook portion 311 can be in the shape of an inverted hook of a right triangle. The other end of the locking member 310 is a limiting end 312. The hook portion 311 is used for clamping with the storage module 200. The limiting end 312 is located between one end of the elastic member 320 and the limiting member 330. The lower end of the elastic member 320 abuts against the housing 340. The elastic member 320 applies an upward elastic force to the limiting end 312 with the housing 340 as a support. One end of the limiting member 330 is located below the limiting end 312, and the limiting end 312 and the end of the limiting member 330 can abut against each other.

[0040] In some specific embodiments of the present utility model, such as Figure 1 and Figure 2 As shown, the locking mechanism 300 is located above the storage module 200. A clamping position 210 is provided at the top of the storage module 200. The clamping position 210 can be in the shape of a concave bayonet inside the top of the storage module 200. The hook portion 311 of the locking member 310 extends downward, and the hook portion 311 can extend into the storage module 200, and the hook portion 311 cooperates with the clamping position 210 for clamping.

[0041] In some embodiments of the present utility model, such as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, a sunken cavity 110 is formed on the substrate 100. The sunken cavity 110 is formed by sinking along the thickness direction of the substrate 100 from a large plane side of the substrate 100. Slide grooves 120 are provided on the left and right sides of the sunken cavity 110. The slide grooves 120 extend vertically downward, and the bottom ends of the slide grooves 120 penetrate downward to the bottom of the substrate 100. Slide rails 230 are provided on both sides of the storage module 200. During installation, the storage module 200 is inserted upward into the sunken cavity 110 from the bottom of the substrate 100, and the upper ends of the slide rails 230 slide upward into the slide grooves 120 from the lower ends of the slide grooves 120. Through the cooperation of the slide grooves 120 and the slide rails 230, the storage module 200 is lifted and lowered in the sunken cavity 110. After the entire slide rail 230 enters the slide groove 120, a plug 400 is installed at the lower end of the slide groove 120. The plug 400 is used to limit the downward travel position of the slide rail 230, which is equivalent to limiting the downward sliding travel of the storage module 200, and preventing the storage module 200 from completely disengaging from the substrate 100 during use. Among them, the storage module 200 is a plate-like structure, and a hanging rod 220 is provided at the bottom of the storage module 200. The hanging rod 220 can extend horizontally and can be used to hang items such as towels and clothes. When the storage module 200 descends to the lowest position, the hanging rod 220 can be moved out below the sunken cavity 110 for convenient use.
