Abstract

PURPOSE: An installation structure of a parking assist sensor is provided to prevent damage of the sensor unit by separating the sensor unit from a bumper cover in the event of a collision. CONSTITUTION: An installation structure of a parking assist sensor comprises a plate-shaped bracket(120) and a sensor unit(130). The bracket is fixed to a bumper back beam(110) installed on the rear of a vehicle. The sensor unit is supported on the upper side of the bracket and fixed to a bumper cover(100) by a fastening member.

Description

Installing structure of a detection sensor

The present invention relates to an installation structure of the parking assistance sensor, and more particularly, to an installation structure of the parking assistance sensor that can prevent damage of the parking assistance sensor in a crash event.

The parking assist sensor provided in the vehicle generates a warning sound when an obstacle is detected within a predetermined distance around the vehicle, so that parking can be performed safely during parking.

In addition to the parking assist sensor, a surveillance camera is provided at the rear to help the driver conveniently park the vehicle while checking backward obstacles at the time of reverse parking.

Such a conventional parking assist sensor or rear surveillance camera is fixed to the rear bumper cover.

Hereinafter, the installation structure of the conventional parking assist sensor will be described.

1 is a view showing the rear of a vehicle equipped with a conventional parking assist sensor, Figure 2 is a cross-sectional view of the line A-A of FIG.

1 and 2, the parking assist sensor 20 is provided in the rear bumper cover 10 provided at the rear of the vehicle. Specifically, a sensor fastening hole is formed in the rear bumper cover 10, and the elastic body 21 is fitted into the hole and the parking assist sensor is supported by the elastic body to be fixed.

In addition to such a shape, a rib is formed to protrude inside the rear bumper cover, and after the assembly of a separate bracket in which the parking assist sensor is fixed to the protruding rib, the rib is fused to fix the parking assist sensor.

As described above, the conventional parking assist sensor is firmly fixed to the rear bumper cover, and thus the operation is performed. Therefore, the impact acting on the bumper cover in the event of a collision is transmitted to the parking assist sensor so that the parking assist sensor is easily damaged, thereby reducing the overall repair cost of the vehicle. There is an increasing problem.

The present invention is to solve the above problems, to provide an installation structure of the parking assist sensor that can minimize the occurrence of damage to the parking assist sensor provided on the bumper side in the event of a crash.

The installation structure of the parking assist sensor of the present invention includes a plate-shaped bracket fixed to a bumper back beam installed at the rear of the vehicle; It is supported by the upper end of the bracket may be provided by the sensor unit which is integrally fixed by the bumper cover and the fixing member.

The installation structure of the parking assist sensor of the present invention comprises a plate-shaped bracket provided in the bumper back beam, and a sensor portion supported on the upper end of the bracket and fixed integrally with the bumper cover. The sensor unit, which is supported on and fixed to the bumper cover, is separated from the bumper cover, thereby preventing direct shock from being transmitted to the sensor unit, thereby preventing damage to the sensor unit.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The installation structure of the parking assist sensor according to the present invention includes a plate-shaped bracket 120 fixed to the bumper back beam 110 installed at the rear of the vehicle; It is characterized by consisting of a sensor unit 130 that is supported on the bracket 120, the bumper cover 100 and the fixing member integrally fixed.

Referring to Figure 3, the bumper back beam 110 of the vehicle body is provided with a plate-shaped bracket 120, the lower end of the bracket 120 is firmly fixed to the bumper back beam 110, such as bolts or welding, the sensor unit 130 on the top ) Is provided. The plate-shaped bracket 120 serves as a leaf spring and elastically supports the sensor unit 130 fixed to the top.

The bracket 120 may have an appropriately bent shape according to the distance between the bumper back beam and the bumper cover so that the upper end may be positioned adjacent to the bumper cover 100.

The sensor unit 130 is provided with a fixing plate 131 to be fixedly supported on the upper end of the bracket 120, the fixing plate 131 is formed with a plurality of holes (131a) formed in the horizontal direction.

In the present invention, the fixing member is broken when the impact of a predetermined size or more on the bumper side is released while the assembly state of the bracket 120, the fixing plate 130, and the bumper cover 100 is released.

As a specific example, as shown in Figure 4, preferably the fixing rib 101 is formed as a fixing member protruding into the bumper cover 100, the fixing rib 101 is for fixing the bracket 120 and It is assembled through the hole 131a of the plate 131. A fixing plate on which the front end portion 101a of the fixing rib 101 penetrating the bracket 120 and the fixing plate 131 is fused to fix the bumper cover 100, the bracket 120, and the sensor unit 130. 131 is integrally fixed.

The fixing rib 101 has a positional relationship substantially perpendicular to the bumper cover 100. Therefore, when the external force acts in the vertical direction between the bracket 120 and the bumper cover 100, the fixing rib 101 is The cutting state of the bracket 120, the fixing plate 130 and the bumper cover 100 is released while being cut.

In addition, the bracket 120 is preferably formed with a blade 121 at one end of the hole through which the fixing rib 101 passes.

The blade 121 of the bracket 120 positioned in contact with the fixing rib 101 is formed on the blade 121 of the bracket 120 when the bumper cover 100 is deformed and the bumper back beam 110 is deformed. Fixing rib 101 is cut by the sensor 130 is separated from the bumper cover 100 to prevent damage due to the impact on the sensor 130.

Looking at the operation example by the installation structure of the parking assist sensor of the present invention configured as described above are as follows.

Referring to FIG. 5, when a collision accident occurs on the rear bumper side, the bumper back beam 110 is pushed to the rear end, and the bracket 120 fixed to the bumper back beam 110 moves to the bottom thereof. ) Is cut so that the fixing plate 131 of the sensor unit 130, which has been fixed to the bumper cover 100 by the fixing rib 101, is separated and the sensor unit 130 is damaged from the impact at the time of the collision. Can be prevented.

The above embodiment is an example for explaining the technical idea of the present invention in detail, and the scope of the present invention is not limited to the above drawings and embodiments.
