A circuit board fixing structure (100) includes a base (3) and a circuit board (2). The base has a plurality of elastic claws (32) and the elastic claws vertically extend from the base. Each elastic claw includes a fastening portion (34), which forms a fastening surface (36) facing to a top surface of the base. The circuit board is encircled by the elastic claws and an upper surface of the circuit board confronts the fastening surface of the fastening portion.

An underrun prevention member for a vehicle bumper beam including a substantially vertical outer side wall faced an area outside the vehicle and a horizontal wall provided so as to be extended substantially horizontally from an end of the outer side wall in a top-bottom direction toward an inside of the vehicle, disposed at a front portion or a rear portion of the vehicle so as to be extended substantially horizontally in a vehicle widthwise direction, and integrally fixed to the bumper beam so as to protrude in the top-bottom direction beyond the horizontal wall to prevent an underrun of the bumper beam under an object outside the vehicle or the object outside the vehicle under the bumper beam.

The invention discloses a bracket. The bracket comprises a bracket body, a cover body, an elastic part and a bottom plate, wherein the bracket body is provided with an arch wire groove in a penetrating way; the bottom plate is arranged at the bottom part of the bracket; the cover body is glidingly matched with the top part of the bracket body, and is used for opening or closing the arch wire groove; a slide bulge is arranged on the cover body, and the elastic part is arranged on the bracket body; the slide bulge is in contact with the elastic part, and is used for extruding the elastic part when the cover body is slide; the elastic part is provided with a notch. The bracket has the advantages that by arranging the elastic part with the notch, the larger locking force can be produced on thecover body, the stress is uniform, and the cover body can be tightly fixed; the size of the notch can be adjusted, so that the self-locking force can be adjusted, and the different self-locking forceis set between different brackets at different tooth positions; the elastic part does not extrude the bracket body and the cover body in the deformation process, so that the damage to the elastic part is avoided.

An underrun prevention member for a vehicle bumper beam including a substantially vertical outer side wall faced an area outside the vehicle and a horizontal wall provided so as to be extended substantially horizontally from an end of the outer side wall in a top-bottom direction toward an inside of the vehicle, disposed at a front portion or a rear portion of the vehicle so as to be extended substantially horizontally in a vehicle widthwise direction, and integrally fixed to the bumper beam so as to protrude in the top-bottom direction beyond the horizontal wall to prevent an underrun of the bumper beam under an object outside the vehicle or the object outside the vehicle under the bumper beam, the underrun prevention member includes: a vertical plate portion integrally fixed to the outer side wall so as to be in surface contact with the outer side wall, protruding in the top-bottom direction beyond the horizontal wall by a predetermined protrusion length, and having a predetermined width in the vehicle widthwise direction; a reinforcement plate portion integrally provided to be continuous with a protruded end of the vertical plate portion, extending from the protruded end toward the inside of the vehicle so as to be bent at an angle in the underrun prevention member, and having a length thereof in a vehicle front-rear direction being shorter than a length of the horizontal wall in the vehicle front-rear direction; and paired side plate portions integrally provided to be continuous with both ends of the reinforcement plate portion in the vehicle widthwise direction extending from the both ends of the reinforcement plate portion toward outer sides in the vehicle widthwise direction, inclined so as to gradually approach the horizontal wall respectively, and integrally fixed to the horizontal wall at an outer end portion thereof, respectively.
