Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a novel integrated machine room-less control cabinet. Background Art

[0002] With the continuous advancement of elevator technology, elevator functions are becoming increasingly diverse, and their intelligence levels are constantly improving. At the same time, people are placing higher demands on elevator equipment for ease of installation, ease of commissioning, and space conservation. Against this backdrop, the miniaturization of elevator components has become a key development trend, allowing them to be completely housed within the hoistway, eliminating the traditional machine room design. Consequently, the machine-room-less elevator emerged and has gradually gained widespread market acceptance.

[0003] In the design of machine-room-less elevators, the elevator control cabinet, as the core component of the elevator control system, has a significant impact on the overall performance and operating efficiency of the elevator. Currently, there are two main layout options for machine-room-less elevator control cabinets: the conventional split-type design and the integrated design outside the hall.

[0004] Conventional split design places the main control part in the cabinet inside the shaft, and in order to meet the elevator standards and maintenance requirements, an inspection cabinet will be added outside the hall (refer to the attached figure in the manual). Figure 1 ). However, this design method has many shortcomings. First, from a cost perspective, the need to configure some functional components, such as emergency stop switches, air switches, power indicator lights, etc., in both the control cabinet in the shaft and the maintenance cabinet outside the hall leads to increased device costs. At the same time, the cables that need to be connected between the two cabinets also increase the cable cost. In addition, the maintenance cabinet and the control cabinet require independent design of two sets of cabinet structures and mounting brackets, which further increases the cost of the cabinet structure. Secondly, from the perspective of installation, debugging, and maintenance convenience, the installation of the control cabinet requires on-site hoisting. During debugging, it is necessary to first enter the car top for inspection and run it to the appropriate position. Small parts can easily fall into the shaft during maintenance and installation, which brings inconvenience to related work.

[0005] The off-hall integrated design integrates the control cabinet and inspection cabinet into a single unit, both installed outside the hall. However, this design approach presents some challenges. Due to the numerous components within the control cabinet, the cabinet is bulky, limiting its application scenarios. For example, the cabinet may be thicker than the wall, with the back protruding from the hoistway wall, hindering the opening and closing of elevator doors and making it impossible to install. The cabinet may be too tall, making inspection and maintenance inconvenient. It may also be too wide, lacking sufficient wall space outside the hall door for installation. Furthermore, since the control cabinet is located outside the hall, users have higher requirements for noise and security features, but the currently common off-hall integrated control cabinets still fall short in these areas. Utility Model Content

[0006] The purpose of this utility model is to propose a new integrated machine room-less control cabinet to solve the technical defects of the current layout of machine room-less elevator control cabinets in terms of cost, installation convenience, application scenarios and user performance requirements.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A new type of integrated machine room-less control cabinet includes a cabinet body with an installation space and a cabinet door that is hinged and opened and closed on the opening side of the cabinet body. A baffle mechanism is fixed around the opening side of the cabinet body, and the baffle in the baffle mechanism extends forward toward the opening direction. When the cabinet door is in a closed state, the cabinet door is surrounded by the baffle mechanism; the cabinet body installation space is arranged from bottom to top with a wiring area, a main control frequency conversion module, a maintenance module, a power supply module, and a function expansion module.

[0009] Furthermore, the baffle mechanism includes a left baffle, a right baffle, a lower baffle and an upper baffle fixed around the opening side of the cabinet body. The left baffle, the right baffle, the lower baffle and the upper baffle are arranged to form an extended space for accommodating the cabinet door. When the cabinet body is installed buried in the wall, the baffle mechanism prevents the cement from affecting the cabinet door when the wall is backfilled.

[0010] Furthermore, a waterproof groove is formed extending around the opening side of the cabinet body, and the waterproof groove is a U-shaped structure. When the cabinet door is closed, the inner side of the cabinet door is against the waterproof groove, and the upper side wall of the cabinet door is inserted between the baffle and the waterproof groove to form a waterproof structure.

[0011] Furthermore, the wiring area is located at the bottom of the cabinet, and the wiring terminals, filter modules and battery drive boards are arranged in a front-to-back double-layer layout in the wiring area. Wire entry holes are symmetrically arranged on both sides of the back panel of the wiring area, and a lead-acid battery is arranged between the two wire entry holes.

[0012] Furthermore, the main control frequency conversion module is located in the middle of the cabinet, and the main control frequency conversion module includes a main control board and a frequency converter arranged in a front-to-back double layer, and a main control board plug-in area is provided on the main control board.

[0013] Furthermore, the maintenance module, power supply module, and function expansion module are located on the top of the cabinet, and a contactor module is also included. The maintenance module, function expansion module, power supply module, and contactor module are arranged in a front-to-back double-layer layout.

[0014] Furthermore, the contactor module includes a contactor and a noise reduction box for accommodating and installing the contactor, and sound insulation cotton is arranged around the noise reduction box.

[0015] Furthermore, the cabinet is provided with mounting brackets around it, so that the cabinet is suitable for both wall and well installation. Mounting holes are reserved at the bottom of the cabinet, so that the cabinet is suitable for floor installation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model proposes a new integrated design of a machine room-less control cabinet. By integrating the main control circuit and the off-hall maintenance module, and adopting a compact double-layer layout and miniaturized design, it achieves effective cost reduction, significantly improves the convenience and safety of installation, maintenance and repair, and comprehensively enhances practicality, providing a highly reliable, efficient and economical solution for occasions such as elevator control.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0029] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0031] like Figure 1-8 As shown, a new type of integrated machine room-less control cabinet includes a cabinet body 10 with an installation space, and a cabinet door 11 that is hinged and opened and closed on the opening side of the cabinet body 10. A baffle mechanism is fixed around the opening side of the cabinet body 10, and the baffle in the baffle mechanism extends forward toward the opening direction. When the cabinet door 11 is in a closed state, the cabinet door 11 is surrounded by the baffle mechanism; the wiring area 104, the main control frequency conversion module 106, the maintenance module 107, the power supply module 108, and the function expansion module 101 are arranged from bottom to top in the installation space of the cabinet body 10.

[0032] It is worth mentioning that the cabinet door 11 is provided with a door lock 12 , and a nameplate 111 and an intercom 112 are provided on the inner side.

[0033] Specifically, as shown in the figure, the baffle mechanism includes a left baffle 13, a right baffle 16, a lower baffle 15 and an upper baffle 17 which are fixed around the opening side of the cabinet body 10. The left baffle 13, the right baffle 16, the lower baffle 15 and the upper baffle 17 are arranged to form an extended space for accommodating the cabinet door 11. In order to realize the wall-embedded installation of the cabinet body, the upper and lower baffles and the left and right baffles designed around the cabinet body can effectively prevent the cement from affecting the cabinet door when the wall is backfilled. The baffles around the cabinet body are all designed with a flat structure, which can effectively reduce the width of the cabinet body without affecting the opening of the cabinet door, thereby reducing the size of the installation hole on the hall door wall, making the product more beautiful.

[0034] Specifically, as shown in the figure, a waterproof groove 100 extends around the opening of the cabinet body 10. The waterproof groove 100 has a U-shaped structure. When the cabinet door 11 is closed, the inner side of the cabinet door 11 abuts against the waterproof groove 100, and the upper side wall of the cabinet door 11 is inserted between the baffle and the waterproof groove 100, forming a waterproof structure. The front of the waterproof groove can achieve an IP54 protection level, effectively preventing moisture from penetrating through the cabinet opening and protecting the electronic components inside the cabinet from moisture.

[0035] Specifically, as shown in the figure, the wiring area 104 is located at the bottom of the cabinet. The wiring area 104 is arranged in a double-layer layout with wiring terminals 1041, filter modules 1042, and battery drive boards. Wire entry holes 103 are symmetrically arranged on both sides of the back panel of the wiring area 104, and a lead-acid battery 102 is arranged between the two wire entry holes 103. The two wire entry holes 103 are used to classify strong and weak electricity, effectively reducing signal interference. The lead-acid battery 102 is convenient for regular replacement, and placing it at the bottom can effectively prevent the impact of battery leakage. Above the wire entry holes 103 is the wiring area, which is convenient for on-site wiring nearby.

[0036] Specifically, as shown in the figure, the main control frequency conversion module 106 is located in the middle of the cabinet. It includes a main control board and a frequency converter arranged in a double-layer configuration, with a main control board plug-in area 105 provided on the main control board. This module adopts a stacked structure design while also taking into account a thin design, resulting in a cabinet thickness of less than 190mm, which meets most wall installation requirements. The main control board contains the main control circuitry and signal plug-in modules, effectively reducing internal cabinet wiring and facilitating on-site plug-in. Compared to previous cabinets, this significantly reduces the cabinet's overall dimensions, facilitates integrated cabinet design, and meets wall-mounted requirements.

[0037] Specifically, as shown in the figure, the maintenance module 107, power module 108, and function expansion module 101 are located at the top of the cabinet, along with a contactor module 109. These modules are arranged in a front-to-back double-layer arrangement. These modules are located at the top of the inverter, and their wiring is pre-wired at the factory. Field wiring is primarily connected below the mainboard connector. This ensures that the components at the top of the cabinet remain relatively neat and clean during actual use, making them convenient for on-site use.

[0038] Specifically, as shown in the figure, the contactor module 109 includes a contactor 1091 and a noise reduction box 1092 for accommodating and installing the contactor 1091. The noise reduction box 1092 is surrounded by sound insulation cotton, which can effectively reduce the noise outside the hall when the control cabinet is running.

[0039] Specifically, as shown in the figure, the cabinet 10 is provided with mounting brackets 14 around it, so that the cabinet can be adapted for wall and well installation. The cabinet 10 has mounting holes reserved at the bottom, so that the cabinet can be adapted for floor installation, such as in an equipment room environment.

[0040] This innovative machine room-less control cabinet features an integrated design, integrating the main control circuits and off-site maintenance modules. This innovative design significantly reduces costs. By avoiding the duplication of functional components, such as emergency stop switches, air switches, and power indicator lights, in the control cabinet and off-site maintenance cabinet, material and manufacturing costs are reduced. Furthermore, because the main control circuits and maintenance modules are housed within the same cabinet, the length of interconnecting cables is significantly shortened, further saving material costs. Furthermore, the integrated design of the maintenance cabinet and control cabinet reduces the number of cabinets and corresponding installation accessories, thereby reducing overall installation costs.

[0041] The integrated design of this new machine room-less control cabinet not only improves cost-effectiveness but also facilitates and enhances safety during installation, maintenance, and inspection. The cabinet can be mounted directly on the wall, eliminating the need to access the car ceiling for commissioning, simplifying operations and improving safety. Maintenance and inspection work can also be performed outside the hall, eliminating the complexity and potential risks of operating within the hoistway. This design allows maintenance personnel to perform their work more conveniently and safely, reducing operational complexity and safety risks.

[0042] The layout of the machine room-less control cabinet of this utility model is compact and reasonable, and it adopts a miniaturized design, which enhances its practicality. The miniaturization of the cabinet components and the double-layer staggered layout make the overall thickness of the cabinet less than 190mm and the total height less than 1300mm, which meets most wall installation requirements. The ultra-thin baffle design effectively reduces the width of the cabinet without affecting the cabinet door opening, reduces the hall door wall opening, and improves the aesthetics and installation flexibility. In addition, the front of the cabinet has achieved an IP54 protection level, ensuring its reliability and durability in various environments. At the same time, the cabinet design is flexible and diverse, suitable for various scenarios such as wall installation, hanging inside the shaft, and floor installation. The internal components are reasonably arranged, the battery is easy to disassemble and install and has a leak-proof design, the on-site operation area is located at the top of the cabinet, the wiring is neat and clean, and the contactor module uses a noise reduction box to effectively reduce the noise outside the hall during the operation of the control cabinet, thereby improving the overall user experience.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0044] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
