Description

Technical Field

[0001] This utility model belongs to the field of elevator-related technology, and in particular relates to an elevator control box and an elevator car. Background Technology

[0002] In the current elevator market, elevator retrofitting services are increasing. Among the various aspects of elevator retrofitting, the modification of the elevator car's human-machine interface (HMI) control module is complex, as older elevator models are inconvenient to replace or upgrade. Specifically, the modification of the HMI control box inside the elevator car typically requires measuring the dimensions of the existing control box and then remanufacturing it based on those measurements.

[0003] Currently, existing elevator control boxes typically include a base box and an operating panel. The base box is generally used to house electrical components. Due to the limitations of the sheet metal material of the base box, the overall thickness and weight of the elevator control box are relatively large. Obviously, the elevator control box with the above structure is not convenient for application in elevator retrofitting. Utility Model Content

[0004] In view of this, it is necessary to provide an elevator control box and elevator car that are thin and lightweight.

[0005] An elevator control box, comprising:

[0006] Back panel, used to fix to the car wall;

[0007] A panel assembly includes a panel, a frame, and a hook. The frame is attached to the panel and connected to the back of the panel, and a cavity for mounting electrical components is formed between the frame and the back of the panel. The hook is mounted on the frame and detachably connected to the back panel for sealing the cavity.

[0008] The panel assembly can be mounted on the back panel via the hook.

[0009] Understandably, when assembling the elevator control box on the car wall, the back panel can be fixed to the car wall first, and then the panel assembly can be installed on the back panel by means of hooks. This can reduce the dimensional control precision during the manufacturing of the elevator control box and facilitate the replacement of the elevator control box during elevator retrofitting. In addition, the elevator control box can use the cavity formed between the frame and the back of the panel to place electrical components, thus realizing the bottomless design of the elevator control box. In this process, by using the frame to be set independently of the panel, the frame can be made of profile, thereby enabling the elevator control box to be lightweight and reduce the overall thickness of the elevator control box.

[0010] In one embodiment, the frame includes a first profile strip, a second profile strip, and a connecting joint, wherein the first profile strip and the second profile strip are connected by the connecting joint;

[0011] The first profile strip is disposed on the length side of the panel, and the second profile strip is disposed on the width side of the panel.

[0012] It is understandable that setting the frame as an assembly structure would facilitate its production.

[0013] In one embodiment, the connector is arc-shaped;

[0014] The connecting joints are connected to the first profile strip and / or the second profile strip respectively by plugging in.

[0015] Understandably, the first profile strip and the second profile strip are connected by a rounded joint, which makes the overall appearance of the frame more ergonomic and improves the overall aesthetics of the elevator control box.

[0016] In one embodiment, the connector is provided with two plug plates, the center lines of the two plug plates being perpendicular to each other;

[0017] One of the plug-in plates is tightly fitted into the first profile strip, and the connecting joint abuts against the first profile strip; the other plug-in plate is tightly fitted into the second profile strip, and the connecting joint abuts against the second profile strip.

[0018] In one embodiment, a first groove is formed on the outer peripheral surface of the first profile strip, and a second groove is formed on the outer peripheral surface of the second profile strip, wherein the second groove communicates with the first groove;

[0019] The elevator control panel also includes an ambient light strip, which is embedded in the first groove and the second groove.

[0020] It is understandable that by embedding ambient light strips in the first groove of the first profile strip and the second groove of the second profile strip, the ambient light strips can be used to create an atmosphere when the elevator control box is in operation, making the elevator control box more stylish and cool, thus meeting the needs of elevator renovation.

[0021] In one embodiment, a plurality of hooks are connected to the first profile strip, and the plurality of hooks are arranged at intervals along the length of the first profile strip.

[0022] Understandably, using multiple hooks along the length of the panel to attach the panel assembly to the back panel improves the assembly stability when installing the panel assembly on the back panel.

[0023] In one embodiment, the elevator control box further includes a maintenance bracket and a maintenance panel, the maintenance bracket being embedded in the panel and covered by the maintenance panel;

[0024] The inspection panel is rotatably connected to the panel and detachably connected to the back panel.

[0025] Understandably, by utilizing the connection between the inspection panel and the panel and back panel, the panel assembly suspended on the back panel can be limited, preventing the panel assembly from detaching from the back panel due to external force, and further improving the assembly stability of the panel assembly on the back panel.

[0026] In one embodiment, a bracket is attached to one end face of the access panel facing the back plate;

[0027] The bracket is provided with a connector, which is connected to the back plate by means of a thread.

[0028] It is understandable that by using the threaded connection between the connector and the back plate, the maintenance panel can be detachably connected to the back plate, thereby reducing the space required in the thickness direction of the elevator control box when the maintenance panel and the back plate are assembled and connected, so as to meet the usage requirements of reducing the overall thickness of the elevator control box.

[0029] In one embodiment, the inspection panel has a through hole through which an external tool can pass and act on the connector.

[0030] Understandably, the through holes on the access panel allow external tools to be inserted through the holes and screwed onto the connectors to control the connection between the access panel and the back panel. This maintains the aesthetic appearance of the access panel and also facilitates the operation of opening or closing the access panel by the staff.

[0031] In addition, this application also provides an elevator car, including a car wall and the elevator control box described above;

[0032] The back panel is fixedly installed on the car wall.

[0033] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0034] The elevator control box and elevator claimed in this application are designed to be lightweight. When the elevator control box is assembled on the car wall, the back panel can be fixed to the car wall first, and then the panel assembly can be installed on the back panel by means of hooks. This can reduce the dimensional control precision during the manufacture of the elevator control box and facilitate the replacement of the elevator control box during elevator retrofitting. In addition, the elevator control box can use the cavity formed by the frame to place electrical components, so that the elevator control box can be designed without a bottom box. In this process, the frame is set independently of the panel, so the frame can be made of profile, thereby reducing the overall thickness of the elevator control box while making it lightweight.

Detailed Implementation

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.

[0046] Unless otherwise defined, 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 invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] like Figure 1 , Figure 3 and Figure 5As shown, an embodiment of this application provides an elevator control panel 100, including a back plate 10 and a panel assembly 20. The back plate 10 is fixed to the car wall (not shown). The panel assembly 20 includes a panel 21, a frame 22, and a hook 23. The frame 22 is attached to the panel 21 and connected to the back of the panel 21, and a cavity 101 for mounting electrical components is formed between the frame 22 and the back of the panel 21. The hook 23 is mounted on the frame 22 and detachably connected to the back plate 10 for sealing the cavity 101. The panel assembly 20 can be mounted on the back plate 10 via the hook 23. Here, the frame 22 can be made of aluminum alloy profile, and the frame 22 can be fixed to the back plate 10 by welding or threading.

[0048] As can be seen from the above, when the elevator control box 100 is assembled on the car wall, the back plate 10 can be fixed to the car wall first, and then the panel assembly 20 can be installed on the back plate 10 by means of the hook 23 in a hanging manner. This can reduce the dimensional control precision when manufacturing the elevator control box 100 and facilitate the replacement of the elevator control box 100 in elevator renovation. In addition, the elevator control box 100 can use the cavity 101 formed by the frame 22 and the back of the panel 21 to place electrical components, so that the elevator control box 100 can be designed without a bottom box. In this process, the frame 22 is set independently of the panel 21, so that the frame 22 can be made of profile, thereby enabling the elevator control box 100 to be lightweight and reduce the overall thickness of the elevator control box 100.

[0049] It should be noted that since the panel assembly 20 in the elevator control box 100 is suspended and mounted on the back plate 10 fixed to the car wall, the size of the panel assembly 20 does not need to be strictly matched with the size of the part on the car wall used to assemble the elevator control box. This reduces the dimensional control precision required when manufacturing the elevator control box 100. On the other hand, the overall external shape of the panel assembly 20 can be adapted to meet different requirements of the elevator control box during elevator retrofitting.

[0050] like Figure 2 As shown, in one embodiment, a hanging groove 11 is provided on the back plate 10, and the hanging groove 11 is correspondingly provided with a hook 23, and the hook 23 can be hung on the back plate 10 through the hanging groove 11. Here, the hanging groove 11 includes an insertion part 111 and a limiting part 112 that are interconnected. The hanging plate 231 on the hook 23 can be inserted through the insertion part 111, and then the hanging plate 231 is driven by the panel 21 to be snapped into the limiting part 112, thereby realizing the vertical suspension of the hook 23 on the hanging groove 11 of the back plate 10.

[0051] like Figure 1 , Figures 3 to 6As shown, in one embodiment, the frame 22 includes a first profile strip 221, a second profile strip 222, and a connecting joint 223. The first profile strip 221 and the second profile strip 222 are connected by the connecting joint 223. The first profile strip 221 is disposed on the length side of the panel 21, and the second profile strip 222 is disposed on the width side of the panel 21. That is, the frame 22 in this embodiment is configured as an assembly structure, which facilitates the production of the frame 22. Here, one first profile strip 221 is installed on each of the two length sides of the panel 21, and one second profile strip 222 is installed on each of the two width sides of the panel 21. Correspondingly, the number of connecting joints 223 in the frame 22 is four. It can be understood that in other embodiments, the length side of the panel 21 is assembled from multiple first profile strips, and the width side of the panel 21 is assembled from multiple second profile strips; this will not be elaborated upon here.

[0052] like Figures 3 to 5 As shown, in one embodiment, the connecting joint 223 is arc-shaped; the connecting joint 223 is connected to the first profile strip 221 and / or the second profile strip 222 respectively by a plug-in engagement. That is, in this embodiment, the first profile strip 221 and the second profile strip 222 on the frame 22 are transitioned by an arc through the connecting joint 223, which makes the overall appearance of the frame 22 more ergonomic and improves the overall aesthetics of the elevator control box 100. Here, the connecting joint 223 is plugged into the first profile strip 221 and the second profile strip 222 respectively. It can be understood that in other embodiments, the connecting joint 223 may also be in the shape of a slanted plate, which will not be elaborated here.

[0053] like Figure 4As shown, in this embodiment, the connecting joint 223 is provided with two plug-in plates 2231, which are perpendicular to each other. Specifically, the center lines of the two plug-in plates 2231 intersect and are perpendicular. One plug-in plate 2231 is tightly fitted into the first profile strip 221, and the connecting joint 223 abuts against the first profile strip 221. The other plug-in plate 2231 is tightly fitted into the second profile strip 222, and the connecting joint 223 abuts against the second profile strip 222. This achieves the splicing of the first profile strip 221, the connecting joint 223, and the second profile strip 222. Here, the connecting joint 223 is configured with an internal hollow structure, and arc-shaped horizontal ribs 2233 and longitudinal ribs 2234 are provided in the hollow cavity 2232 of the connecting joint 223 to improve the overall structural strength of the connecting joint 223. Here, both the first profile strip 221 and the second profile strip 222 are hollow structures with hollow cavities. The inner walls on both sides of the hollow cavity are respectively extended with ribs, and the ribs and the bottom surface of the hollow cavity form a slot. The two slot plates 2231 are respectively engaged with the slots of the first profile strip 221 and the second profile strip 222.

[0054] like Figure 1 , Figure 3 and Figure 5 As shown, in one embodiment, a plurality of hooks 23 are connected to the first profile strip 221, and the hooks 23 are arranged sequentially at intervals along the length direction of the first profile strip 221. This allows the panel assembly 20 to be hooked onto the back plate 10 using the plurality of hooks 23 on the length side of the panel 21, thereby improving the assembly stability of the panel assembly 20 when installed on the back plate 10. Here, the number of hooks 23 on each first profile strip 221 is two, three, or even more, and the hooks 23 on two first profile strips 221 are arranged symmetrically in the width direction of the panel 21. Each hook 23 can be fixed to the first profile strip 221 by bolts 201 welded to it, which pass through the hook 23 and are screwed to the first profile strip 221 between the bolt and the nut 202. It is understood that in other embodiments, the hooks 23 can also be fixed to the first profile strip 221 by welding or bonding, which will not be elaborated here.

[0055] like Figure 7 As shown, in one embodiment, the hook 23 further includes an L-shaped plate 232, one side of which is attached to the first profile strip 221 and fixed with bolts 201 and nuts 202; wherein, the hook 23 has a mounting plate 231 on the other side of the L-shaped plate 232, which can be connected to the L-shaped plate 232 as a whole.

[0056] like Figure 5As shown, in one embodiment, the elevator control box 100 further includes a maintenance bracket 30 and a maintenance panel 40. The maintenance bracket 30 is embedded in the panel 21 and covered by the maintenance panel 40. The maintenance panel 40 is rotatably connected to the panel 21 and detachably connected to the back plate 10. This allows the operator to first disconnect the maintenance panel 40 from the back plate 10, and then perform maintenance on the corresponding electrical components on the maintenance bracket 30 by flipping the maintenance panel 40. This facilitates subsequent maintenance operations on the elevator control box 100. During this process, the connection between the maintenance panel 40, the panel 21, and the back plate 10 can be used to limit the panel assembly 20 suspended on the back plate 10, preventing the panel assembly 20 from detaching from the back plate 10 due to external force, thus further improving the assembly stability of the panel assembly 20 on the back plate 10.

[0057] like Figure 5 As shown, in one embodiment, a bracket 41 is connected to one end face of the inspection panel 40 facing the back plate 10; a connector 42 passes through the bracket 41 and is threadedly connected to the back plate 10. That is, the inspection panel 40 can be detachably connected to the back plate 10 via the threaded connection between the connector 42 and the back plate 10. This reduces the space required in the thickness direction of the elevator control box 100 when assembling the inspection panel 40 and the back plate 10, thus meeting the requirement of reducing the overall thickness of the elevator control box 100. Here, the bracket 41 is U-shaped, and it can be fixed to the inspection panel 40 by welding or screwing.

[0058] like Figure 5 As shown, in this embodiment, the connector 42 is configured as a bolt or screw.

[0059] like Figure 3 As shown, in this embodiment, the inspection panel 40 is provided with a through hole 401, which allows an external tool to pass through and act on the connector 42. That is, the through hole 401 is aligned with the connector 42 in the thickness direction of the elevator control box 100. This maintains the aesthetic appearance of the inspection panel 40 and facilitates the operation of opening or closing the inspection panel 40 on the panel 21 by the staff.

[0060] like Figure 5 , Figure 6As shown, in one embodiment, the elevator control box also includes an ambient light strip 200, which is embedded within the frame 22. When the elevator control box is in operation, the ambient light strip 200 illuminates the elevator control box within the elevator car, creating a more stylish and sophisticated atmosphere to meet the needs of elevator retrofitting. Here, the ambient light strip 200 is embedded within a first groove 2211 on the outer periphery of the first profile strip 221 and a second groove 2221 on the outer periphery of the second profile strip 222. Specifically, the ambient light strip 200 can be an RGB light strip, allowing it to produce different colors of light when in operation. It should be noted that the ambient light strip 200 illuminates when a button in the elevator control box is pressed, which will not be elaborated upon here.

[0061] In addition, this application also provides an elevator car, including a car wall and the elevator control box 100 described above; the back plate 10 is fixed to the car wall.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
