Problems solved by technology

As a result, the assembly structure of metal decorative parts is complicated, the assembly work increases, and parts for forming a holding structure for drop resistance are required, resulting in an increase in the number of parts and cost
In addition, in the structure of the portable wireless key, the number of switches (operating parts) differs for each vehicle, so the appearance design of each switch is required, and even if the number of switches is the same, there are differences in function configuration, so changing the switch becomes difficult. very huge
Furthermore, in order to cope with such a switch change, for example, as shown in Patent Document 1, a case member is produced for each switch, but there is a problem that the initial cost becomes high.

Embodiment Construction

[0032] The portable wireless key of this embodiment is applied to, for example, an electronic key system represented by keyless entry of a vehicle, a smart entry system, and a smart start system, and at least has a wireless communication function for wireless communication with the vehicle side, and at least utilizes the The control related to the locking / unlocking of the door lock of the vehicle is implemented by wireless communication. In such an electronic key system, the vehicle side wirelessly outputs polling radio waves within a predetermined key search area, and completes the search for portable wireless keys existing in the key search area based on the wireless reception of its response signal, and compares the data from the key search area. The ID code wirelessly received by the portable wireless key implements predetermined vehicle control based on the comparison result.

[0033] The portable wireless key of this embodiment is configured as a smart key in a so-called...

Abstract

In this portable wireless key, a decorative fitting (123) provided to the tip end of a pair of side edges (121) of a metal decorative member (120) are locked by a decorative locking section (15) at the wireless key main body (3) side, and a decorative engagement section provided to the joining sides (122) of the metal decorative member (120) is locked by a decorative locking section (17) at the wireless key main body (3) side. Also, a switch operation cover (130) is attached to an assembly of the wireless key main body (3) and the metal decorative member (120). As a result, it is possible to improve anti-dropping properties without an increase in cost, the number of components, or the work of assembling the metal decorative member (120), and it is possible to easily respond to switch variations without an increase in initial cost.

Description

technical field [0001] This application is based on Japanese Application No. 2013-225036 filed on October 30, 2013, and the content of the description is incorporated herein. [0002] The present disclosure relates to a portable wireless key that performs at least control related to locking / unlocking a door lock of a vehicle by wireless communication with a vehicle. Background technique [0003] In recent years, electronic key systems such as smart entry systems have provided portable wireless keys that perform wireless communication for performing control related to locking / unlocking doors of vehicles. Such a portable wireless key is held by a person like a mobile phone and needs to be resistant to falling. In recent years, due to improvement in design (decorativeness), there has been an increase in the number of products using zinc die-cast parts for portable wireless keys as metal decorative parts. In this case, the weight increases compared with conventional resins, an...
