Problems solved by technology

However, there are still shortcomings in this linear motor design, that is: the driving body of the curtain needs to use alternating current, so it is necessary to use brushes or trailing cables to solve the power supply problem, and the above-mentioned design is especially not suitable for only direct current. Powered Car Curtains
Checking the patent applications in my country from April 1, 1985 to January 10, 2004, there is no open design of electric curtains that do not require cables for the curtain drive body itself and use linear motors at the same time.

Embodiment 1

[0017] Embodiment 1: This embodiment is an example of applying the present invention to a horizontally driven curtain.

[0018] figure 1 It is the appearance and partial section view of the curtain in this example.

[0019] Figure 4 It is a cross-sectional schematic diagram of a curtain moving iron type DC linear motor using a rod stator and a tubular mover in this example.

[0020] Figure 5 It is a schematic diagram of the structure of the mover pulling ear of the circular tubular curtain linear motor in this example. What this picture shows is the curtain drive puller with closed tubular structure composed of three tile-shaped magnets, and its magnetization method is radial magnetization.

[0021] The opening or closing of the curtain is accomplished by the two opposite movements of the linear motor mover, which must be realized by a circuit that can reverse the current direction of the linear motor winding. image 3 Shown relay type curtain opening and closing direct...

Embodiment 2

[0024] Embodiment two: the present embodiment is an example of the present invention being used for the design of automobile rear curtain, figure 2 is its schematic diagram. The difference between this example and the previous example is that the one adopts two sets of identical (rod-shaped stator, tubular mover) moving iron type DC linear motors simultaneously, and the 2nd, uses the same curtain DC linear motor controller (20), Even the same curtain opening and closing direction control circuit (24) and the same curtain linear motor drive execution circuit (25) can be used to simultaneously control the two sets of linear motors. The third is to take into account the characteristics of the rear window of the car and adopt the up and down drive type. When the curtain is closed, the driving lugs on both sides simultaneously and synchronously upwardly drive the curtain, and the curtain is pulled out from the curtain winder (10). When the curtain is opened, the driving lugs on ...

Embodiment 3

[0025] Embodiment three: Image 6It is a cross-sectional schematic diagram of a moving iron type DC linear motor for curtains with another structure. The cross-section of the driving lug (1) of the linear motor is "U" shape, with a winding stator inside and a permanent magnet mover (2) outside. Its winding is also wound by a number of segmented windings (4). There is a mover (2) composed of two permanent magnets in the driving ear (1) of the curtain. The surface of the magnet close to the winding stator (6) is also a magnetic pole. The permanent magnet mover (2) in the driving lug (1) can perform the movement of opening and closing the curtain along the long axis direction of the winding stator. The control principle and control mode of the linear motor in this example are completely the same as in the first embodiment. In this example, the auxiliary stator (7) shaped like an outer cover is made of ferromagnetic material, and it is fixedly installed near the outside of the ...

Abstract

The electrically driven curtain with linear DC motor for indoor and automobile use has driver of moving iron type linear DC motor and has no power source in the mover, no brush and no moving cable. The linear DC motor mover track may be used also as the curtain track. The electrically driven curtain has low power consumption, low noise and beautiful appearance. Adopting DC motor makes the electrically driven curtain suitable for automobile use. One simple voltage reducing rectifier may be added for convenient use conveniently with AC power supply in hospital and household.

Description

technical field [0001] The invention relates to the field of electric curtains, in particular to the field of electric curtains using a DC linear motor as a power source. Background technique [0002] Electric curtains are increasingly widely used in all kinds of cars, as well as homes, offices, buildings, halls, halls, and places. Generally all adopt to install a rotating motor, allow motor to drive gear or pulley, then drive the method and technology of curtain stay cord. This method not only affects the appearance, but also has the problem of motor noise and unreliability. There are also patent applications for electric curtains without drawstrings, such as patents No. 93208319.6 and 94106858.7, and patents for electric curtains specially designed for automobiles, such as patents No. 01217842. The patent application for 01125886.1 related to electric curtains for automobiles. But they all still contain rotating electric machines and mechanisms. Some electric curtain d...
