Problems solved by technology

[0006] However, in the structure disclosed in the above-mentioned patent document 1, there is the following technical problem: when the holding part of the ultrasonic sensor module is arranged on the back of the bumper of the vehicle, it is necessary to align the holding part with the hole of the bumper (need to use alignment tool) so that the assembly part of the ultrasonic sensor module accommodated in the holding part can be inserted into the hole of the bumper, so it cannot be easily installed

Embodiment approach 1

[0026] Figure 1 ~ Figure 3 Methods (1) to (3) of attaching an ultrasonic sensor module to a bumper using the attaching device according to Embodiment 1 are shown. The mounting device of the present invention has: an ultrasonic sensor module 1 ; an anti-interference elastic body 2 ; and a fixing ring plate composed of a fixing part 3 , a holding part 4 and an engaging part 5 . Figure 4 It is a front view showing the mounting device in the state where the fixing part 3 is assembled in the ultrasonic sensor module 1, Figure 5 It is a front view showing the attachment device in the state where the fixing part 3 and the holding part 4 are assembled in the ultrasonic sensor module 1 .

[0027] The ultrasonic sensor module 1 is formed to be inserted into the mounting hole 7 of the bumper 6 toward the mounting portion 8 assembled to the bumper 6 of the vehicle and engaged with the mounting hole 7 , and a diameter-ratio mounting hole is formed at the base of the mounting portion 8 ...

Embodiment approach 2

[0052] In Embodiment 2, a fitted engaging portion 5 is used instead of the sliding engaging portion 5 in Embodiment 1. As shown in FIG. Figure 7 An example of the fitting engagement part 5 comprised by the engagement claw 5e and the engagement hole 5f is shown. The figure is equivalent to Figure 5 Cross-sectional view taken at the position of line C-C' shown. The holding part 4 and the fixing part 3 are connected together by elastically deforming the engaging claw 5 e as an elastic member formed in the holding part 4 and engaging with the engaging hole 5 f formed in the fixing part 3 . Since the sliding claw 5e fits into the engaging hole 5f, the connection between the holding portion 4 and the fixing portion 3 is not easily detached even if vibration of the vehicle is received. When disconnecting, the engaging claw 5e is lifted from the engaging hole 5f.

[0053] In addition, in Figure 7 In the above, the engaging claw 5e is formed on the side of the holding part 4, an...

Embodiment approach 3

[0056] In the third embodiment, the fixing part 3 in the first embodiment is divided into a plurality of Figure 8 Plates 3-1 to 3-4 are shown. The engaging parts 5 may be of the sliding type in Embodiment 1, or may be of the embedded type in Embodiment 2, and are provided on the plates 3-1 to 3-4, respectively. By using the individual plates 3-1 to 3-4, the fixing portion can easily conform to the shape of the bumper 6, so that adhesive fixing to the curved bumper 6 can be easily performed.

[0057] In addition, when the fixing parts are the plates 3-1 to 3-4, the mounting methods (1) to (3) of Embodiment 1 can also be applied. In particular, in the mounting method (1), since the plates 3-1 to 3-4 are connected to the holding portion 4 with the engaging portion 5 as a fixed ring plate and then assembled to the ultrasonic sensor module 1, it is different from the mounting method (2). ), (3) compared to improve the operability.

[0058] As described above, according to Embod...

Abstract

An ultrasonic sensor module 1 is inserted into an attaching hole 7 provided in a bumper 6 of a vehicle to be thereby temporarily positioned therein, then a fixing ring plate, which is formed by fitting a holding section 4 in a hole 3a of a fixing section 3 and further connecting the holding section and the fixing section to each other with a fitting section 5, is mounted to the ultrasonic sensor module 1 from the back of the bumper 6, and the fixing section 3 is fixed to the back of the bumper 6 through an adhesive member 11 while pressing a flange 9 of the ultrasonic sensor module 1 with the holding section 4.

Description

technical field [0001] The present invention relates to a mounting device and a mounting method for mounting an ultrasonic sensor module on, for example, a bumper of a vehicle. Background technique [0002] Conventionally, as such a mounting device and mounting method, as disclosed in Patent Document 1, the holding part of the ultrasonic sensor module is provided on the back of the bumper of the vehicle, and the ultrasonic sensor module is accommodated in the holding part from the back of the bumper. And the surface of the assembly part of the ultrasonic sensor module protruding from the end surface of the holding part is arranged to be coplanar with the surface of the bumper. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent No. 4056568 Contents of the invention [0006] However, in the structure disclosed in the above-mentioned patent document 1, there is the following technical problem: when the holding part of the ul...
