Abstract

PURPOSE:To make operability and heat radiation from heating parts excellent, to make the device compact and to facilitate attaching by forming the PC board of a metal base in a box shape, mounting parts on the inner PC board, exposing the operating part to the outside, and providing an attaching part. CONSTITUTION:A metal base 1a is formed as a case having a U-shaped cross section. A PC board 16 is formed at said base 1a. Wirings 3 are provided on the inner side of the PC board 1b. Parts 2a are directly attached to the PC board 1b and mutually connected. A heating part 2a is fixed to the base 1a through the board 1b so that the heat can be radiated, An exposed part is formed at the outside of the base 1a. Operating parts such as a switch 7 are attached from the outside so that the operating parts can be readily operated. Flanges 4 are formed. The flanges can be readily fixed to a door 6 and the like with screws 5. Since the density of the parts mounted on the base 1a can be made very high, the compact configuration is realized. The side part is closed with a lid. Therefore, intrusion of dust can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for operating automatic doors and the like.

[Prior Art] Control devices for automatic doors, etc. are required to be miniaturized because they are provided with the automatic door, and are housed in a small case and designed so that it can be placed in any part. .

In the case of an automatic door, such a compact control device requires control of a considerable amount of electric power because it includes a control circuit for an electric motor that opens and closes the door, and there is a limit to miniaturization due to heat dissipation.

Furthermore, automatic doors require complex control elements, such as torque control according to the wind pressure generated on the door as the door closes and closes, and a stop function when the door comes into contact with a human body.

For this reason, the control circuit has a large number of circuit elements and includes components that require heat dissipation, resulting in limitations associated with miniaturization.

[Problems to be Solved by the Invention] When miniaturizing a control device, the first problem is heat radiation from heat-generating components, and the second problem is dissipating a large number of components in a limited space. It is to accommodate.

Furthermore, control circuits for automatic doors and the like must be able to be installed in any desired manner and must be sealed to prevent dust from entering from the outside.

The present invention was made in view of these circumstances, and
The purpose is to provide a control device that can be used under conditions such as automatic doors.

[Means for solving the problems] The present invention mounts components on a metal-based PC board, and
The problem is solved by making the metal IX side of the C plate outside, providing an attachment part on this outside, and exposing the operating part on the outside.

[Function] Because the components are mounted on a metal-based PC board, the heat from the heat-generating components is conveniently dissipated.However, since there is no PC board made of insulating plates for other components, the limited space is required. Various parts can be effectively mounted on the PC board, and since the metal base can be used as a case, switches for operation can be mounted directly on the PC board of the metal base and exposed to the outside. This is easy and provides sufficient mechanical strength for storage.

A metal-based PC board can be easily formed into a box-shaped case, and can be configured to prevent dust from entering by closing the opening or attaching a lid. can.

[Embodiment] The present invention will be described based on an embodiment shown in the drawings. Fig. 1 is a vertical cross-sectional view of a main part of a control device of the present invention, and Fig. 2 is a perspective view thereof.

In FIGS. 1 and 2, the control device is a PC consisting of a metal base 1a formed in a case with a cone-shaped cross section.
A Cl2O component 2 is mounted, and wiring 3 is provided inside the PCCl2O to connect the components 2 to each other.

When forming PCCl2O on the metal base 1a, the wiring 3 is provided through an insulating member, and the component 2 is attached directly to the wiring 3.

The component 2 includes a heat generating component 2a, and the heat generating component 2a is fixed to the metal base 1a via an insulating member made of PCCl2O so as to radiate heat.

The metal base 1a is formed with a collar 4 for attachment, and is configured to be fixed to a door 6 or the like with screws 5.

Furthermore, the metal base 1a has an exposed part formed on the outside, and operating parts such as a switch 7 are housed so as to extend into this exposed part, so that they can be operated from the outside. It is configured.

In FIG. 2, the control device is constructed in such a way that a lid 8 is provided so that the open side portion can be closed.

In this rectangular configuration, the control device includes a PC board ib formed inside a metal base 1a formed in a U-shape, and a wiring 3
Attach part 2.2a to and assemble.

Then, parts such as the switch 7 are exposed and attached to the outside by utilizing the mechanical strength of the metal base 1a.

Furthermore, a storage 8 is attached to the open part of the side and the door 6
Fix it with screw 5.

When assembled in this way, the control device can be attached to any part of the door 6, and the density of necessary components such as the parts 2.2a and the switch 7 mounted on the metal base 1a is extremely high, making it compact. will be realized.

In addition, the heat radiation of the heat generating component 2a reaches the door 6 via the metal base la, resulting in a large heat radiation effect, and it is possible to eliminate obstacles to miniaturization.

[Effects of the Invention] According to the present invention, the metal base is formed into a box shape and P is formed inside.
By forming a C board, attaching components to the PC board, improving heat dissipation of heat-generating components, and increasing the mounting density of components, it is possible to achieve miniaturization, and it is easy to install as a control device for automatic doors, etc. It is easy to operate and its effects are extremely large.
