All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In one embodiment of the present application, as shown in fig. 1, 2, 3, 6, 7, and 9, an elevator call box includes a bottom case 1 capable of being embedded in a wall body, and a panel 2 fitted to the bottom case 1, an edge of the panel 2 extends out of an outer periphery of the bottom case to form an abutting portion 21, a gasket 22 for abutting against the wall surface is stacked on a side of the abutting portion 21 facing the bottom case, and an outer edge of the gasket 22 is inwardly caulked with respect to an outer edge of the panel 2.

The thickness of the panel 2 is less than 2mm, the gasket 22 is made of elastic material and surrounds the bottom box 1 for a circle, and the thickness of the gasket 22 is 0.5mm-3 mm.

As shown in fig. 8, in a conventional elevator call box, an installation room 31 communicating with a hoistway is provided in a wall 3. The bottom box 1 of the elevator calling box is fixed in the installation chamber 31, and the panel 2 is positioned outside the installation chamber 31 and needs to be attached to the surface of the wall 3. However, in actual use, a clearance hole is opened on the panel 2 to satisfy installation of human-computer interaction elements (such as a display, an upper button, a lower button, a fire switch, a key switch, etc.). The more interaction elements and the more avoidance holes the panel 2 is assembled at a certain thickness, the longer the panel 2 has to be designed, so that the strength of the panel 2 becomes lower. 2 both ends of panel are fixed, and the centre is not atress, and when laminating with wall body 3, the middle part takes place to arch easily, just has gap 4 between this arch position and the wall body 3, under extreme condition, when pressing the button, panel 2 can rock, and the light in the end box can shine the outside through the gap, influences the outward appearance of product.

The deformation of the central part of the panel 2 is not easy to be perceived, and the influence on the whole appearance of the elevator calling box is small. In contrast, the deformation of the edge of the panel 2 directly causes the generation of the gap 4 and the light leakage at the periphery of the elevator calling box, and the appearance of the elevator calling box is seriously affected. In the embodiment, the gasket 22 is adopted for reinforcing the edge part of the panel 2, so that the deformation of the edge of the panel 2 is reduced, and the appearance of an elevator calling box is ensured.

By reinforcing only the edges of the panel 2, the overall thickness of the panel 2 does not have to be increased, allowing the thickness of the panel to be maintained at 2mm, thereby saving material costs.

The spacer 22 is designed to be annular, and the central hole can be penetrated by the interactive element, so as to avoid changing the original circuit structure in the bottom case 1.

The gasket 22 may be fixed to the panel 2 in advance or the gasket 22 may be selected on site according to the installation environment of the wall, and the gasket 22 is attached to the wall surface by the clamping force of the panel 2.

In an embodiment the faceplate is directed towards the back box in a first direction, the faceplate 2 obscuring the gasket 22 from view in the first direction. The first direction is substantially perpendicular to the wall surface and is also the primary direction in which elevator passengers view the elevator call box. By shielding the gasket 22 from the panel in the first direction, the gasket 22 can be allowed to have a greater thickness, which both increases the strength of the periphery of the panel 2 and ensures the overall appearance of the elevator call box.

In one embodiment, the face material 2 is stainless steel and the gasket 22 is foam, rubber or plastic. The foam, the rubber and the plastic are soft materials, and deformation matched with the shape of the gap is easy to occur. For example, the gasket may be a sponge.

To facilitate field installation, in one embodiment, the gasket is adhesively secured to the panel. The gasket 22 is bonded to the panel 2 in advance, so that the influence on the appearance of the elevator calling box is small, the positioning link of the gasket 22 on site is omitted, and the operation is convenient. For example, the gasket may be double-sided tape, pre-bonded to the panel, and further bonded to the wall during field installation.

In practical application, it is found that when the thickness of the panel 2 exceeds 2mm, the arched size of the panel 2 is small, and at the moment, the gap caused by the uneven wall body only needs to be considered, and the gap can be filled through the gasket. When the thickness of the panel 2 is less than 2mm, the influence of the arching of the panel 2 is large. In order to further reduce the deformation of the panel 2, in one embodiment, as shown in fig. 10, the panel 2 is provided with a reinforcing plate 5 on the side facing the back box 1, and the gasket 22 is fixed against the reinforcing plate 5. The shape of the reinforcing plate 5 is consistent with that of the panel 2, and the reinforcing plate 5 is equivalent to increase the total thickness of the panel, so that the panel 2 is not easy to deform. The reinforcing plate 5 may be made of a material cheaper than the face plate 2 to reduce cost.

In one embodiment, the reinforcing plate is made of plastic or metal. For example, the reinforcing plate 5 is a plastic plate, and the reinforcing plate 5 may be fixed to the face plate 2 in advance by bonding or heat pressing, thereby increasing strength and reducing cost.

The panel 2 is made of a single-layer stainless steel plate, which can play a role in beauty and corrosion prevention, and the material requirement of the reinforcing plate 5 can be properly reduced, for example, a galvanized plate is adopted. The panel 2, the reinforcing plate 5 and the gasket 22 are mutually superposed, so that the strength and the aesthetic property can be considered.

Specifically, in one embodiment, the gasket is adhesively secured or in contact engagement with the panel.

To ensure the appearance of the elevator call box, in one embodiment, the outer edges of the panel, the stiffener and the spacer are successively converged as shown in fig. 4. For example, the edges of the stiffener plate converge inwardly 0.5-3mm relative to the edges of the panel, and the edges of the shim converge inwardly 0.5-3mm relative to the edges of the stiffener plate.

In one embodiment, the panel 2 is made of stainless steel, the signal processing board is installed in the bottom box, the button, the display, the fire switch and the key switch are installed on the panel, and the reinforcing plate 5 is made of 1mm-3mm galvanized plate.

The panel is provided with a plurality of pairs of first clamping pieces on one side facing the bottom box, a plurality of pairs of second clamping pieces correspondingly clasped with the pairs of first clamping pieces are arranged in the bottom box, and the clasped parts of the first clamping pieces and the second clamping pieces are provided with guide inclined planes to drive the panel and the wall body to clamp the gasket. When the panel is installed, the first clip 23 and the second clip 24 are folded to generate a pulling force F (as shown by the arrow in fig. 9) for driving the panel 2 to move toward the wall 3. The pulling force F tends to flatten the arching of the panel 2 on the one hand and clamps the gasket 22 between the panel 2 and the wall 3 on the other hand. After installation, the gasket 22 deforms by itself to conform to the shape of the gap between the abutment 21 and the wall 3, thereby preventing light leakage. In the present embodiment, the spacer 22 may be fixed to the back surface of the panel 2 in advance, or may be separate from the panel 2.

During installation, the bottom box is fixed on the wall body 3, and then the panel 2 and the bottom box 1 are buckled, so that the installation is convenient. When the two clamping pieces are buckled, the first clamping piece and the second clamping piece are mutually embraced, the second clamping piece generates a pulling force F towards the wall body 3 to the first clamping piece, the wall body 3 generates a supporting force (not shown) to the attaching part 21 at the edge of the panel 2, the two clamping pieces are mutually balanced and clamp the gasket 22 to fill the gap 4, and light leakage is prevented.

Specifically, the first clamping piece and the second clamping piece are contacted with each other through the guide inclined plane, and the acting force between the first clamping piece and the second clamping piece inclines relative to the wall body due to the fact that the acting force is perpendicular to the guide inclined plane, so that a pulling component perpendicular to the wall body and a limiting component parallel to the wall body are obtained. Through setting up first clamping piece in pairs, set up the second clamping piece in pairs, can make the spacing component that acts on same pair of first clamping piece balance each other and offset to form total pulling force F.

In order to facilitate the installation of the clips in pairs, in one embodiment, as shown in fig. 4, 5 and 6, the clips (including the first clip 23 and the second clip 24) of the same pair form an integral structure through a connecting portion 25, the panel 2 and the bottom case 1 are fixed with a butt-welding screw 26, and the connecting portion 25 of each pair of clips is inserted and fixed with the corresponding butt-welding screw 26 and locked by a nut matched with the butt-welding screw.

Specifically, the part including the two first clamping pieces 23 and the connecting portion 25 is an upper clamp, the part including the two second clamping pieces 24 and the connecting portion 25 is a lower clamp, and each connecting portion 25 is provided with a pair of mounting holes. The back of the panel 2 is welded with butt-welding screws 26 in pairs, two mounting holes of the upper clamp are sleeved outside the two butt-welding screws 26 of the panel 2, and the upper clamp is fixed on the back of the panel 2 through nuts. The butt-welding screws 26 are welded on the bottom box 1 in pairs, two mounting holes of the lower clamp are sleeved outside the two butt-welding screws 26 of the bottom box 1, and the lower clamp is fixed with the bottom box 1 through nuts. When the bottom box 1 and the panel 2 are buckled, the bottom box 1 generates a pulling force F towards the wall body to the upper clamp and the panel 2 through the lower clamp.

To reduce the extension length of the first clip 23, in one embodiment, as shown in fig. 7, the second clips 24 are distributed inside the peripheral wall of the bottom case 1 and extend toward the central region of the bottom case. The bottom case 1 is a case body with an opening on one side and comprises a bottom wall and a peripheral wall. When the bottom box 1 is deep, the second clamping piece 24 is arranged on the peripheral wall, so that the second clamping piece 24 is closer to the panel 2, and the first clamping piece 23 does not need to extend too long towards the inside of the wall 3.

Specifically, in an embodiment, as shown in fig. 7 (the first clip piece and the second clip piece are not deformed), at least one of the first clip piece and the second clip piece 24 that are folded together is made of an elastic material, the first clip piece 23 is provided with an expanding section 231 that is away from each other, one side of the two expanding sections opposite to each other is provided with a guiding inclined surface 232 of the first clip piece, the second clip piece 24 is provided with a limiting section 241 that is attached to the outer side of the two expanding sections, and one side of the two limiting sections opposite to each other is provided with a guiding inclined surface 242 of the second clip piece.

For example, the first clamping piece 23 is made of elastic material, and when the two expanding sections 231 of the first clamping piece 23 are fastened, they approach each other through elastic deformation. After the fastening, the second clip piece 24 exerts a pressing force N (as shown by the arrow in fig. 7) perpendicular to the guiding slope 232 of the first clip piece, and the same pair of pressing forces N results in a pulling force F.

The application provides an elevator calling box, when guaranteeing product outward appearance and intensity, the cost is reduced and the wall laminating better.
