Description

Technical Field

[0001] This utility model relates to the field of elevator control box technology, and in particular to a panel assembly for an elevator control box. Background Technology

[0002] An elevator control box consists of a panel and a base box. The inside of the panel is usually lined with a lining plate. The lining plate serves two purposes: firstly, it provides a stable mounting base for control components such as buttons, displays, and circuit boards, ensuring that they do not loosen or shift under vibration or external impact during elevator operation; secondly, it enhances the rigidity of the box, preventing the control box shell from deforming due to frequent operation or compression, and extending the service life of the overall structure.

[0003] For example, in the elevator control box with patent number CN210710192U, the inner lining is a single piece of board that covers the entire inner wall of the panel. In the prior art, the lining is generally glued to the inner wall of the panel. The glued area is basically the same as the area of ​​the lining to ensure the stability of the lining after glue. However, a large glued area will lead to high glue cost and longer glue time. Utility Model Content

[0004] This utility model provides a panel assembly for an elevator control box, which reduces the adhesive cost of the lining plate on the inner side wall of the main panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An elevator control panel assembly includes a main panel and a backing plate;

[0007] The aforementioned lining plate includes a first plate and a second plate, and both the first plate and the second plate are provided with an adhesive layer between them and the inner sidewall of the main panel.

[0008] The first plate and the second plate are spaced apart and are respectively disposed on the inner sidewalls of the two ends of the main panel distributed along the width direction;

[0009] The adhesive layer includes a first adhesive layer and a plurality of second adhesive layers, both of which are located on the inner sidewall of the main panel. The first adhesive layer is a silicone layer, and the second adhesive layers are a mixture of silicone and AB glue.

[0010] Preferably, the first plate and the second plate respectively form multiple projection areas on the corresponding plate with the multiple second adhesive layers between them and the inner sidewall of the main panel, and the multiple projection areas are evenly distributed along the length direction of the corresponding plate.

[0011] Preferably, on the same plate, the total area of ​​the plurality of the above-mentioned projection areas does not exceed 1 / 10 of the total area of ​​the plate.

[0012] Preferably, the two ends of the main panel distributed along the width direction are respectively provided with a first bending portion and a second bending portion, and both the first plate and the second plate are configured as L-shaped;

[0013] The first horizontal plate in the first plate body is glued to the inner side wall of the main panel near the first bend, and the first vertical plate inside it abuts against the third vertical plate in the first bend that is connected to the main panel.

[0014] The second horizontal plate in the second plate body is glued to the inner side wall of the main panel near the second bend, and the second vertical plate inside it abuts against the fourth vertical plate in the second bend that is connected to the main panel.

[0015] Preferably, both the first plate and the second plate have multiple overflow holes on their horizontal plates.

[0016] Preferably, the second plate is provided with a stud, through which a hinge can be connected.

[0017] Preferably, the first plate and the second plate are provided with spherical grooves on the sidewalls near the main panel, and the opening of the spherical grooves is smaller than the diameter of the spherical grooves.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By dividing the entire liner into a first plate and a second plate, the adhesive area of ​​the liner is reduced, thereby reducing adhesive costs and adhesive time.

[0020] 2. This design divides the adhesive layer between the board body and the main panel into a first adhesive layer and a second adhesive layer. Most of the adhesive area is the first adhesive layer, which is composed of silicone. Compared with using AB glue, this greatly reduces the adhesive cost. Attached Figure Description

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figures 1-7 As shown, this utility model embodiment provides a panel assembly for an elevator control box, including a main panel 1 and a backing plate 2. The backing plate 2 is installed on the inner side wall of the main panel 1. On the one hand, it provides a stable mounting base for control components such as buttons, displays, and circuit boards, ensuring that they will not loosen or shift under vibration or external impact during elevator operation. On the other hand, it enhances the flatness of the entire panel, increases the support rigidity, prevents the control box shell from deforming due to frequent operation or squeezing, and extends the service life of the overall structure.

[0035] In the prior art, the backing plate 2 is a single piece of board with multiple cutouts. Circuit components are installed in the corresponding cutouts. The backing plate 2, excluding the cutouts, is laid on the inner wall of the main panel 1, occupying most of its area. It is then glued to the inner wall of the main panel 1. While this ensures the supporting strength of the main panel 1, it requires a large amount of glue, leading to a long connection time. Furthermore, the glue used is typically AB glue, resulting in high cost. Therefore, in this embodiment, the backing plate 2 is composed of a first plate body 21 and a second plate body 22. Specifically, the first plate body 21 and the second plate body 22 are spaced apart, and both the first plate body 21 and the second plate body 22 are connected to the inner wall of the main panel 1 by an adhesive layer 3. Both are mounted to the inner wall of the main panel 1 through the adhesive layer 3. Because the total area of ​​the first plate body 21 and the second plate body 22 is smaller than the area of ​​the inner wall of the main panel 1, the total area of ​​the two adhesive layers 3 is also smaller than the area of ​​the inner wall of the main panel 1, thus reducing costs. The area of ​​the adhesive layer 3 is reduced, thus lowering the adhesive cost. It also reduces the time required to install the backing plate 2 on the inner wall of the main panel 1, accelerating the assembly speed. Simultaneously, the first plate 21 and the second plate 22 are respectively disposed on the inner walls of the two ends of the main panel 1 along its width direction. Both the first plate 21 and the second plate 22 are disposed along the length direction of the main panel 1 and are of equal length, ensuring that the first plate 21 and the second plate 22 cover the entire inner wall of both ends of the panel along its length direction. This guarantees the support strength of the two ends of the main panel 1 after bending and also fulfills the function of the mounting base. Specifically, the adhesive layer 3 includes a first adhesive layer 31 and multiple second adhesive layers 32, both located on the inner wall of the main panel 1 and on the same horizontal plane. The first adhesive layer 31 is a silicone layer, and the second adhesive layer 32 is a mixture of silicone and AB glue. Since the main component of the silicone layer is silicone, which is much cheaper than AB glue, the cost of using the adhesive is directly reduced. Specifically, in actual use, the AB adhesive used is model CL-3230, and the silicone adhesive is model G-533L. The AB adhesive is more expensive than the silicone adhesive. The mixing ratio of AB adhesive and silicone adhesive in the second adhesive layer 32 is 1:9.

[0036] Specifically, because multiple second adhesive layers 32 are provided and contain AB glue, in order to make the connection between the first plate 21 and the inner wall of the main panel 1 more stable, multiple second adhesive layers 32 containing AB glue between the first plate 21 and the inner wall of the main panel 1 have corresponding projection areas 4 on the first plate 21. The multiple projection areas 4 are evenly distributed along the length direction of the first plate 21, and are adhered by the second adhesive layers 32 at intervals, which can make the adhesion of the first plate 21 more stable. Of course, apart from the projection area 4, the remaining areas on the first plate 21 can be the projection areas of the first adhesive layers 31 on the first plate 21. The ideal situation is that all the remaining areas are the projection areas of the first adhesive layers 31. The first adhesive layer 32, containing AB glue, forms multiple projection areas 4 on the second plate 22 between the second plate 22 and the inner wall of the main panel 1. These projection areas 4 are evenly distributed along the length of the second plate 22, and are adhered to by the second adhesive layer 32 at intervals, making the adhesion of the second plate 22 more stable. Of course, excluding the projection areas 4, all other areas on the second plate 22 can be projection areas of the first adhesive layer 31. Ideally, all other areas should be projection areas of the first adhesive layer 31, making the connection between the second plate 22 and the inner wall of the panel more stable. Specifically, in this embodiment, there can be three second adhesive layers 32, each with a first projection on the first plate 21. These three first projections are respectively located at the upper, middle, and lower parts of the first plate 21 along its length, and are glued and fixed in three parts. The remaining areas are all glued and fixed by the first adhesive layer 31.

[0037] Preferably, on the same board, the total area of ​​multiple projection areas 4 does not exceed 1 / 10 of the total area of ​​the board. That is, in the same adhesive layer 3, the total horizontal area of ​​the second adhesive layer 32 does not exceed the total horizontal area of ​​the adhesive layer 3, avoiding the situation where the area of ​​the second adhesive layer 32 is too large, thus increasing the adhesive cost. Here, the horizontal plane refers to the plane where the inner sidewall of the panel is located, and the adhesive layer 3 is glued to the inner sidewall of the main panel 1, and its surface is parallel to the inner sidewall of the main panel 1. The aforementioned horizontal area of ​​the second adhesive layer 32 refers to the surface area of ​​the second adhesive layer 32, and the horizontal area of ​​the adhesive layer 3 refers to the total surface area of ​​the adhesive layer 3. Moreover, it is known that the specific area of ​​the second adhesive layer 32 is specifically set by the processing personnel, but as long as the total area does not exceed 1 / 10 of the total area of ​​the adhesive layer 3, it can control costs and ensure connection strength.

[0038] Specifically, in the prior art, the two ends of the main panel 1 along the width direction are respectively provided with a first bending portion 5 and a second bending portion 6. In this embodiment, the first plate 21 and the second plate 22 are both set as L-shaped. Specifically, the first plate 21 includes a first horizontal plate 211 and a first vertical plate 212, the second plate 22 includes a second horizontal plate 221 and a second vertical plate 222, the first bending portion 5 has a third vertical plate 51, the third vertical plate 51 is connected to the main panel 1, and the second bending portion 6 has a fourth vertical plate 61, the fourth vertical plate 61 is connected to the main panel 1. The connection is such that when the first plate 21 is glued, the first horizontal plate 211 inside the first plate 21 is glued to the inner side wall of the panel near the first bend 5, and the first vertical plate 212 inside it abuts against the third vertical plate 51 inside the first bend 5, thereby strengthening the connection strength of the first bend 5. Similarly, the second horizontal plate 221 inside the second plate 22 is glued to the inner side wall of the main panel 1 near the first bend 5, and the second vertical plate 222 inside it abuts against the fourth vertical plate 61 inside the first bend 5, thereby strengthening the connection strength of the second bend 6.

[0039] Preferably, in order to make the first plate 21 and the second plate 22 more easily pressed onto the adhesive layer 3 during the adhesive bonding process, multiple overflow holes 7 are provided on the first horizontal plate 211 of the first plate 21 and the second horizontal plate 221 of the second plate 22. When the plate is pressed onto the adhesive layer 3, the adhesive in the adhesive layer 3 can be discharged from the overflow holes 7 instead of being discharged entirely from the edge of the horizontal plate, which can greatly reduce the resistance when the adhesive escapes and save effort in pressing. Specifically, multiple overflow holes 7 are provided along the length direction of the horizontal plate and are evenly distributed.

[0040] Specifically, studs 223 are riveted onto the second plate 22, and hinges 11 can be connected by bolts. The bottom shell 9 and the main panel 1 inside the entire elevator control box are rotatably connected. The relative rotation between the bottom shell 9 and the main panel 1 is achieved by setting hinges 11. An L-shaped connecting plate 10 is set on the bottom side wall of the bottom shell 9. The horizontal plate inside the L-shaped connecting plate 10 is fixed to the inner side wall of the bottom shell 9, and the vertical plate inside it is connected to one end of the hinge 11. The other end of the hinge 11 is fixed to the first plate 21 by studs 223, thus fixing the hinge 11. This allows the hinge 11 to be connected to the second plate 22, rather than fixed to the inner side wall of the main panel 1, thereby ensuring the support strength of the main panel 1.

[0041] Specifically, to further enhance the connection strength between the first plate 21 and the second plate 22 and the main panel 1, spherical grooves 8 are provided on the side walls of the first plate 21 and the second plate 22 near the main panel 1, and the opening of the spherical groove 8 is smaller than the diameter of the spherical groove 8. Thus, during the adhesive bonding process, when the first plate 21 and the second plate 22 are pressed to the corresponding adhesive layer 3, the adhesive will enter the spherical groove 8. After the adhesive is completely solidified, spherical adhesive columns will be formed in the spherical groove 8. Since the opening of the spherical groove 8 is smaller than the diameter of the spherical groove 8, the spherical groove 8 will limit the spherical adhesive columns, so that the spherical adhesive columns will not detach from the spherical groove 8. This further ensures that the first plate 21 and the second plate 22 are tightly attached to the adhesive layer 3 and tightly connected, thus ensuring the connection stability between the plate and the adhesive layer 3.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
