Description

  The present invention relates to an ignition key fixing jig and an ignition key fixing jig attaching / detaching structure provided in a drive robot applied to, for example, a chassis dynamometer.

  As a device for testing the power performance of various vehicles such as passenger cars and trucks, a chassis dynamometer capable of simulating the driving state of the test target vehicle is applied indoors and the like, and the test target vehicle is operated. It is known to use a drive robot for this purpose. As an example of this drive robot, there is one that turns on / off a vehicle to be tested with an ignition key and includes an ignition key actuator that is driven by a motor or the like.

  Here, as a fixing jig (so-called key cup or chucking) for holding the ignition key, for example, the ignition key is held so as to be covered with a bottomed cylindrical member, or held so as to be sandwiched (for example, 2 (For example, Patent Documents 1, 2, 3, and 4).

  FIG. 9 is a schematic diagram for explaining an example of an ignition key fixing jig in a general drive robot. Reference numeral 101 in FIG. 9 denotes an ignition key that can be inserted into and removed from the key hole 103 formed in the ignition box 102 of the vehicle to be tested. Reference numeral 104 denotes an actuator 104 that is operated by a drive source 105 such as a motor. The ignition key 101 is provided with a bottomed cylindrical fixing jig 106 that is detachably held. For example, a universal joint 105 b for connecting to the output shaft 105 a of the drive source 105 is provided at the end of the drive source 105. By operating this actuator 104 and inserting the ignition key 101 into the key hole 103 and turning it, the vehicle to be tested can be turned on / off.

  The ignition key 101 is mounted by inserting at least a part thereof (the grip portion 101a in FIG. 9) into the side wall of the fixing jig 106, and is held by the frictional force of the contact between the inserted portion and the inner surface of the side wall. However, it is required to prevent the ignition key 101 from dropping during the test. As this drop-off preventing means, for example, a means for fixing the grip portion 101a or the like by a biasing means (spring or the like) or a fastening means (screw or the like) is known.

  In recent years, various types of ignition key mechanisms have been developed along with the technical progress of vehicles. Conventionally, for example, as shown in FIG. 9, a mechanism for simply turning the vehicle on / off by simply inserting the ignition key 101 into the key hole 103 has been mainstream, but the ignition key and vehicle (ignition box, etc.) A wireless communication mechanism capable of wireless communication (transmission and reception of electronic data, etc.) has been developed, such as a function that can prevent car theft (so-called immobilizer, etc.) However, many of them having a function that can be locked are beginning to be applied.

  In the case of a general wireless communication mechanism, a device required for wireless communication using an ignition key is built in a grip portion or the like of the ignition key. Further, instead of being inserted into the key hole 103 as shown in FIG. 9, the vehicle is turned on / off via a separately provided switch (button type or the like) in a state where the ignition key is simply arranged in the vicinity of the ignition box, for example. Some of them can be turned off.
