no. 1 Embodiment approach

[0034] Below, refer to Figure 1 to Figure 5 A description will be given of a first embodiment in which the vehicle exterior is embodied as a logo attached to the front of the vehicle.

[0035] In addition, regarding the following description, the forward direction of a vehicle is set to the front, and the backward direction is set to the back, and demonstrates it. In addition, the up-down direction indicates the up-down direction of the vehicle, and the left-right direction is the vehicle width direction, and is set to match the left-right direction when the vehicle is moving forward. In addition, in each drawing, in order to make each part of a car logo recognizable, the scale of each part is appropriately changed and shown.

[0036] like image 3 As shown, a millimeter-wave radar device 13 for monitoring the front is disposed at the center portion in the vehicle width direction of the front portion of the vehicle 10 and behind the front grille 11 . The millimeter wave ra...

no. 2 Embodiment approach

[0081] Below, refer to Image 6 and Figure 7 A description will be given of a second embodiment in which a vehicle exterior is embodied as a vehicle logo.

[0082] The structure of the water stop part 71 of 2nd Embodiment differs from 1st Embodiment. The water stopper 71 is constituted by a cover made of a hard resin material. In the second embodiment, the water stopper 71 is formed of AES resin similarly to the base body portion 23 .

[0083] The water stop portion 71 is disposed with the gap G1 interposed between the connector pins 32 and the joint portions 56 a and 56 b and the terminal portions 57 a and 57 b of the joint portion 58 . The water stop portion 71 is a peripheral edge portion 72 of the window portion 30 located on the front side (outer peripheral side) of the joint portion, and is welded to a portion surrounding the joint portion. For example, welding is performed by a welding method such as ultrasonic welding, laser welding, and hot plate welding.

Abstract

The invention relates to an exterior decoration for a vehicle, which can well maintain the connection state of a heater wire relative to a connector pin even if the surrounding temperature changes repeatedly. A vehicle logo (15) as an exterior decoration for a vehicle is provided with a decoration main body (21), a heating sheet (51), and a connector pin (32). The decorative main body part is provided with a base material (22) and a transparent resin layer (35), and the heating sheet is provided with a heating main body part (52) and an extending part (53). A portion of the protruding portion of the heater wire (57) is joined to the connector pin (32) inside the outer peripheral portion (22a) of the base material by a joining portion (58). In the outer peripheral portion, a window portion (30) for joining the heater wire (57) and the connector pin through a joining portion (58) is formed in a state in which the joining portion is exposed to the outside of the outer peripheral portion. The window portion is provided with a water stop portion (71) that restricts the entry of water into the joining portion. The water stop portion is formed by filling the window portion with a potting material.

Description

technical field [0001] The present invention relates to vehicle exterior ornaments for decorating vehicles such as vehicle emblems, decorative parts, signs, and the like. Background technique [0002] In a vehicle incorporating a millimeter wave radar device, millimeter waves are transmitted from the device toward the outside of the vehicle. The millimeter wave reflected by contact with an object outside the vehicle including a preceding vehicle, a pedestrian, etc. is received by the above-described millimeter wave radar device. The recognition of the above-mentioned object, the detection of the distance between the vehicle and the object, the relative speed, etc. are performed using the transmitted and received millimeter waves. [0003] In the above-mentioned vehicle, vehicle exterior decorations such as a car logo are arranged in front of the millimeter wave radar device in the transmission direction of the millimeter wave. The vehicle exterior has a decorative body por...
