Description

This invention relates to a throttle grip device in which the vehicle's power source is controlled based on the rotational operation of the throttle grip. In recent motorcycles, throttle grip devices have become widespread that detect the rotation angle of the throttle grip using a throttle opening sensor such as a potentiometer, and send the detected value as an electrical signal to the electronic control unit installed in the motorcycle. Based on this detection signal, the electronic control unit performs predetermined calculations, and the motorcycle's drive source (e.g., engine ignition timing, intake valve or throttle valve opening/closing) is controlled based on the calculation results. A conventional throttle grip device is, for example, the one disclosed in Patent Document 1. In this conventional throttle grip device, the throttle grip and the interlocking member are connected by engaging an engaging portion formed on the throttle grip with an engaged portion formed on the interlocking member. Engine control is performed by detecting the rotation angle of the throttle grip using a sensor that detects the rotation angle of the interlocking member.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. As shown in Figures 1 and 2, the throttle grip device according to this embodiment detects the rotation angle of the throttle grip G attached to the handlebar H of a motorcycle and transmits the detection signal to an electronic control unit such as an ECU mounted on the motorcycle to control the drive source (engine). As shown in Figures 3 to 10, it is configured to include a throttle grip G, a case 1, an interlocking member 2, a first biasing means 3, a second biasing means 4, a rotating member 5, a magnetic sensor 9 (rotation angle detection means), and a resistance force applying means 7. Case 1 is installed inside a switch case S (see Figures 1 and 2) attached to the tip end of the handlebar H of a motorcycle (vehicle) (the base end of the throttle grip G). It houses various components constituting the throttle grip device and rotatably holds the interlocking member 2 and the rotating member 5, etc. As shown in Figure 13, Case 1 consists of a molded part with a first housing section 1a for rotatably housing the interlocking member 2, a second housing section 1b for rotatably housing the rotating member 5, a third housing section 1c for housing the resistance force applying means 7, a stopper section 1d to which the protruding portion 6b of the biasing force selection means 6 can abut, and a locking section 1e for locking one end of the first biasing means 3. Reference numeral 11 indicates a plate-shaped lid member for closing the opening side of Case 1. The throttle grip G extends from the switch case S and is designed to be rotated by the driver while being held. As shown in Figures 1 and 2, it is capable of forward rotation (a) in a predetermined direction around its axis from its initial position, and reverse rotation (b) in the opposite direction. An engaging portion Ga (see Figure 6), which has a protruding shape, is formed at the base end of the throttle grip G. This engaging portion Ga engages with the engaged portion 2a (see Figures 5, 7, 11, etc.) of the interlocking member 2, thereby connecting the throttle grip G and the interlocking member 2. The interlocking member 2 has a concave-shaped engaged portion 2a that can engage with the engaging portion Ga formed on the throttle grip G, and can rotate in conjunction with the forward rotation a and reverse rotation b of the throttle grip G. Specifically, as shown in Figure 11, the interlocking member 2 according to this embodiment consists of an annular member having an engaged portion 2a, a pair of housing portions 2b, a flange 2c, and a gear 2d.
