RU2420645C2 - Method to locate container of accumulators of electrically controlled roller blind - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: method to locate a container of accumulators of electrically controlled roller blind made of a cylindrical tube closed with a plug at one end, and having an output shaft of a reducer at the other end, includes installation of a tube motor inside the body so that the container and the motor make a monoblock with autonomous power supply. The container holds cylindrical accumulators to supply to a tube DC motor, which puts the device in motion.

EFFECT: simplified assembly and service, to exclude electric connections between components when items similar to roller blinds are assembled.

Description

Application area

The invention relates to structural elements of protective devices for closing window, door and similar openings and can be used in electrically controlled roller blinds.

State of the art

The prior art device roller curtains [1]. In this solution, the DC motor is equipped with batteries charged by a solar battery. The engine is controlled using the remote control.

The prior art device roller curtains [2]. In this solution, the rotation to the roller with the roll of the curtain is transmitted from the electric motor, combined with sliding bearings, providing free rotation of the outer tube of the roller blind or other lifting device driven by a DC motor. The closest analogue is electrically operated roller blinds [3] with an internal motor and autonomous power supply from a battery pack located next to the device and connected to it by a power cable. The device is a motor with a sleep mode and a built-in radio receiver, the power of which is provided by an external battery pack consisting of a cylindrical container, inside of which a motor is placed, combined with sliding bearings, providing free rotation of the outer tube of a roller blind or other lifting device driven by an internal motor direct current.

The disadvantage of all known solutions is that the batteries (pencil case with batteries) or the power supply for the roller blind are located outside, it requires free space for installation, as well as additional fastening, which complicates the installation of the product and worsens its appearance. In general, this either increases the dimensions of the product, or requires the installation of a curtain to hide the power supply or batteries somewhere within the window due to the removal of wiring and the installation of additional fasteners. In addition, the consumer must either independently disconnect and disassemble the pencil case to replace the batteries, or use the services of a customer service.

The aim of the invention is the task to develop a universal method of creating a structure that does not contain parts difficult to manufacture, easily adaptable to various types of existing roll and other cassette or open type lifting systems using DC internal motors without making significant changes to the external design of the finished products, which will also simplify and speed up their installation.

The technical result of the invention is to reduce the size, simplify installation and maintenance, the exclusion of electrical connections between components during assembly of products like roller blinds.

The implementation of the invention

The claimed technical result is achieved due to the fact that the method of placing the battery container of an electrically controlled roller blind made of a cylindrical tube closed at one end by a stopper and having an output shaft of the gearbox at the other end, characterized in that the container containing cylindrical batteries inside to power the intra-direct current DC motor that drives the device, it is installed inside the housing of the intra-internal motor so that the container and the motor l make together a monoblock with autonomous power. In a monoblock, an additional controller board with an integrated radio is installed.

The use of cylindrical batteries allows you to fully complete the design of the parts of rotation, simple to manufacture and assemble. The resulting finished assembly with small dimensional changes can be placed inside the tubular profiles of various sizes used in the manufacture of roller blinds or other lifting mechanisms. The method can be implemented as follows. Rechargeable batteries (6) (see Figure 1), a DC motor (2) with a gearbox (3), a controller board with a built-in radio receiver (5) are located in one housing (1), which is a pipe, on one side of which is located the output shaft of the gearbox (4), and on the other hand, the end cap (7) is the cap of the drive housing, combined with a sliding bearing (8), in which an electrical connector (9) is also installed for charging the batteries.

The body (1) is a pipe, the material of which can be either metal or plastic, the length and diameter are determined by the overall dimensions and the number of batteries used (6). In the event that the tube of the housing (1) is made of metal, its inner wall must be isolated from the battery housing. Plain bearings (8) can be made of nylon, polyamide, fluoroplastic or other dielectric materials with similar properties. The plug (7) and all other elements, except the output shaft of the gearbox (4), are rigidly fixed in the pipe of the housing (1) and together with the batteries located inside (6) are a single monoblock stationary part of the structure. Batteries can be connected to each other by soldering, resistance welding or by means of spring-loaded contacts, and the wires from them are brought out and connected to the load (motor) and external connector (9) for connecting the charger. When assembling a roller blind or other lifting mechanism, the described case (1), consisting of parts (2, 3, 5, 6, 7, 8, 9) and which is a complete assembly, is simply installed inside the rotating tube of the roller blind. This operation does not require additional skills from the product collector.

In the assembly, a roller blind (see Figure 2) from one end facing the inside of the product, the pipe (11) is closed by a plug (7), and from the other by an external support (12), which together with the rings (8) form sliding bearings. The roller (10) of the engine is located on the end of the shaft (4) of the gearbox and rotates the tube (11) with a roll of curtains. This design is convenient in that it allows you to position the engine with the drive shaft outward and remove all wiring into the body structure (1).

Claims (2)

1. The method of placing the battery container electrically controlled roller blinds made of a cylindrical tube, closed at one end by a stopper, and at the other end having an output shaft of the gearbox, characterized in that the container containing cylindrical batteries inside, designed to supply an intravenous DC motor, driving the device, set inside the body of the intra-shaft engine so that the container and the engine together form a monoblock with autonomous power. 2. The method of placing the battery container of the electrically controlled roller blind according to claim 1, characterized in that the controller board with an integrated radio is further installed in the monoblock.
