Description

  The present invention relates to a mobile unit mounting apparatus.

  Conventionally, various electric components such as a radio receiver, a television receiver, a navigation device, and a DVD (Digital Versatile Disk) player are mounted on a moving body such as a vehicle. Such an electrical component includes a device having a mechanical structure in order to function as an apparatus, and a printed circuit assembly (hereinafter also referred to as “PCA”) for controlling the device. Here, the PCA includes a printed wiring board on which a predetermined conductor pattern is formed, and circuit components mounted on the printed wiring board (hereinafter also referred to as “PWB”).

  Such electrical components generally have a metal casing (see Patent Document 1). In particular, for electrical components having a mechanism for rotationally driving a storage medium such as a hard disk device or a DVD drive device, a metal member such as a steel plate is used as a material for the housing in order to take measures against vibrations generated during movement of the moving body. Is adopted.

The following configuration (hereinafter referred to as “conventional example”) is generally employed when a metal casing is used that has a mechanism for rotationally driving such a storage medium. That is, a device 910 having a mechanism for rotationally driving a storage medium such as an optical disk drive is made of a metal bracket member 920 via a metal bracket member 920 as in the electrical component 900 generally shown in FIGS. Fixed to the housing 940. And this housing | casing 940 is fixed to metal vehicle brackets (601,606).
Japanese Utility Model Publication No. 5-56651

  In the case of having the fixing structure as in the above-described conventional example, vibration generated when the vehicle travels is transmitted from the vehicle bracket to the device having a mechanism for rotating the storage medium through the housing. Here, in the conventional example, since the strength of the casing can be ensured by adopting a metal casing as the casing, it is possible to suppress the occurrence of resonance in the device due to the vibration generated when the vehicle travels. Can do.

  However, if the material of the housing 940 is made of resin in the conventional example for weight reduction, since the resin is inferior in strength to metal, resonance in the device 910 is likely to occur due to vibration that occurs during vehicle travel. . For this reason, if the material of the housing 940 in the conventional example is simply made of resin having low mechanical strength, there is a concern that the occurrence of a situation in which data cannot be continuously read when data recorded on the recording medium is read. Is done. The occurrence of such a situation leads to the occurrence of sound skipping and video skipping during audio / video playback.

  In addition, when a metal casing is employed as in the conventional example, the ground pattern formed on the PCA PWB and the casing are electrically connected by a metal member, thereby stabilizing the ground pattern. Potential level. This is because the metal housing is electrically connected to a large metal member called a chassis of the moving body by being a good conductor and being connected to a metal fixing member prepared for the moving body. It is to be done.

  However, if the housing is made of resin for weight reduction, even if a conductive resin is used, the conductive resin is inferior in conductivity compared to metal, so it is formed on the PWB like the metal housing. The potential level of the ground pattern cannot be stabilized. Therefore, if the housing is simply changed from metal to resin for weight reduction, there is a concern that the stability of the operation of the mobile unit mounting apparatus is deteriorated.

  The same situation as the situation related to the stability of the potential level of the ground pattern is also assumed for heat dissipation of a high heat-generating component such as a power transistor. In other words, as in the conventional example, when a metal casing is used, efficient heat dissipation can be achieved by connecting the heat-dissipating part of a high heat-generating component such as a heat-dissipating fin to the metal casing via a metal member. It is possible to effectively prevent an excessive temperature rise of the high heat-generating component.

  However, if the case is made of resin for weight reduction, even if a conductive resin is adopted, the conductive resin is inferior in thermal conductivity compared to metal, so to the same extent as the metal case, It is impossible to suppress the temperature rise of high heat-generating parts. Therefore, if the housing is simply changed from metal to resin for weight reduction, there is a concern that the stability of the operation of the mobile unit mounting apparatus is deteriorated.

  For this reason, there is a need for a technique that can reduce the weight of the mobile body mounting device while eliminating the above-described concerns. Meeting this requirement is one of the problems to be solved by the present invention.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a movable body mounting apparatus that can reduce the weight while ensuring operational stability.

  The invention according to claim 1 is a device having a mechanical structure; a printed circuit assembly in which circuit components for controlling the device are disposed on a printed wiring board; and a movable body connected to the device A metal bracket member connected to a metal fixing member prepared in the above and electrically conducting with a ground pattern formed on the printed wiring board; and a resin bracket housing the device and the printed circuit assembly A moving body mounting device comprising: a housing member;
