Description

  The present invention relates to an assembly structure in which a device to be mounted on a vehicle and a bracket for holding the device are assembled, and a bracket to which the device can be assembled.

  In recent years, devices such as an object detection sensor for detecting an object such as a preceding vehicle, a pedestrian, or an obstacle existing around the vehicle are mounted on the vehicle for the purpose of improving the safety of the vehicle. Devices such as these object detection sensors are mounted, for example, at the left and right corners of a bumper provided in front of or behind the vehicle.

  However, since the structure of the mounting location such as the inside of the bumper to which these object detection sensors are attached differs for each vehicle model, the object detection sensor manufactured according to the specifications of a predetermined vehicle model is used as it is for other vehicle models. It was difficult to divert. Therefore, the object detection sensor is arranged at a desired position of the vehicle even if it is a car of a different vehicle type by assembling the object detection sensor to the bracket and fixing the bracket to an appropriate position of the vehicle body.

Disclosed is an assembly structure in which a device including a guide protrusion protruding from a device main body and a locking portion provided on the other side of the guide protrusion is mounted on a bracket provided with an insertion hole provided. Has been.

  In the assembly structure disclosed in Patent Document 1, the guide protrusion and the locking portion are inserted into the guide hole and the insertion hole, respectively, and the bracket is slid to the other side with respect to the device. Thus, the guide protrusion is held while being guided by the guide hole, and a locking claw provided in the locking portion is locked to the other end of the guide hole, so that the device and the device It is said that the flange can be fixed.

  However, the assembly structure can fix the flange and the device with a simple configuration, but because the locking portion is locked along the sliding direction of the flange, for example, by vibration of the vehicle body, There is a possibility that the locked state between the locking portion and the guide hole is released, and the device is inadvertently detached from the flange and disposed in a state where it is detached from a predetermined position.

A method of assembling the object detection sensor 2 and the sensor holding unit 3 having such a configuration will be described below with reference to FIGS.
First, the extension part 22 extended from the lower both ends of the object detection sensor 2 is inserted into the insertion port S formed by the convex part 33 and the pivot support part 34 (see FIG. 4), and the extension part 22 is inserted. It accommodates in the pocket 32 (refer FIG. 5).

  Next, the base end side front surface of the extension part 22 inserted into the pocket 32 is brought into contact with the pivot support part 34, and the contact surface between the pivot support part 34 and the extension part 22 is used as a pivot axis. The object detection sensor 2 is pivoted counterclockwise (see FIG. 5). As a result, the device main body 21 rises and is pivoted to a position where the concave portion 25 provided in the extending portion 22 and guided by the pocket 32 is engaged with the convex portion 33 (FIGS. 6A and 6B). )reference).

  Further, the object detection sensor 2 is pivoted so as to go to the assembled state, whereby the concave portion 25 is guided to the convex portion 33 formed in a tapered shape, and the concave portion 25 and the convex portion 33 are fitted to each other. The detection sensor 2 and the sensor holding part 3 can be fixed (see FIG. 6B and FIG. 7). As a result, the device main body 21 is erected along the height direction H, and the device main body 21 is installed in the device installation space I formed in the frame 31 so that the surface 21a is the front surface. (See FIG. 7). The bottom surface of the device main body 21 installed in the device installation space I is arranged on the lower frame 31a.

  Moreover, since the position of the object detection sensor 2 with respect to the sensor holding part 3 is accurately determined by fitting the concave part 25 and the convex part 33, the fixing through-hole 26 provided in the fixing part 23 is provided. The fixing screw receiving portion 35 is disposed at the position of the fixing screw receiving portion 35, and the locking piece 36 sandwiches the fixing portion 23 to be temporarily fixed.

  In this state where the object detection sensor 2 is temporarily fixed to the sensor holding unit 3, the object detection sensor 2 and the sensor holding unit 3 are screwed into the fixing through hole 26 and the fixing screw receiving unit 35. And fix. Thereby, the sensor assembly structure 1 in which the object detection sensor 2 and the sensor holding unit 3 are assembled can be prepared. For example, the sensor assembly structure 1 is fixed to the vehicle body fixing portion and the vehicle body, and the sensor assembly structure 1 is placed in a desired position. Can be arranged.

  The sensor assembly structure 1 having such a configuration includes an object detection sensor 2 to be mounted on a vehicle and a sensor holding unit 3 that holds the object detection sensor 2 and can be attached to a vehicle body. Is provided in the sensor holding part 3 so as to support the pivoting so that the sensor holding part 3 is in an assembled state with respect to the sensor holding part 3, and an extension part for fixing the object detection sensor 2 and the sensor holding part 3 to each other. 22 is provided with the pivot support portion 34 provided on the bracket-side fixing portion 32a, the object detection sensor 2 and the sensor holding portion 3 can be easily and easily fixed with a simple configuration.

  More specifically, the sensor assembly structure 1 is configured such that the object detection sensor 2 supported by the pivot support portion 34 is pivoted toward the assembled state, so that the recess 25 provided in the extension portion 22 is provided. And the object detection sensor 2 and the sensor holding | maintenance part 3 can be fixed by the pivot support part 34 which protruded from the bracket side fixing | fixed part 32a. That is, the object detection sensor 2 and the sensor holding unit 3 can be assembled with a simple configuration and easy operation of pivoting the object detection sensor 2.

Further, the bracket-side fixing portion 32a is provided with a convex portion 33 that protrudes toward the object detection sensor 2 in the assembled state, and the extending portion 22 is provided with a concave portion 25 that can be fitted to the convex portion 33. Since the protruding direction of the convex portion 33 and the extending portion 22 provided with the concave portion 25 intersect each other in the assembled state, the convex portion 33 and the concave portion 25 are pivoted by pivoting the object detection sensor 2. It is fixed by fitting with pressure. Therefore, the object detection sensor 2 and the sensor holding part 3 can be fixed easily and firmly.
Moreover, since it is the structure which fits the recessed part 25 and the pivot support part 34, positioning of the object detection sensor 2 with respect to the sensor holding | maintenance part 3 can be made easy by pivot operation.

  Furthermore, the convex portion 33 and the pivot support portion 34 are arranged in an opposing direction, and the surface 21a, the extension portion 22 and the bracket side fixing portion 32a which are the surfaces of the object detection sensor 2 are pivot support portions. The arrangement position of the apparatus main body 21 with respect to the sensor holding part 3 can be adjusted by being arranged on the opposite side via 34.

  Specifically, since the convex portion 33 and the pivot support portion 34 face each other, more specifically, the pivot support portion 34 is provided on the front side (+ D side) of the surface 21a, and the convex portion 33 is on the back side. Since it is provided on the (−D side), the surface 21a of the object detection sensor 2 in the assembled state is disposed on the pivot support portion 34 side (+ D side). In this case, it is possible to adjust the position of the surface of the object detection sensor 2 with respect to the sensor holding unit 3 by adjusting the length of the pivot support part 34 along the protruding direction (depth direction D) of the convex part 33. it can.

  More specifically, if the length of the pivot support part 34 is increased, the surface 21a which is the surface of the device main body 21 is also disposed rearward (−D direction side). When the distance is shortened, the surface 21a is disposed forward (+ D direction side). That is, the object detection sensor 2 can be arranged at a position corresponding to the characteristics of the object detection sensor 2 by adjusting the length of the pivot support portion 34.

  For example, in an ultrasonic sensor using ultrasonic waves such as the object detection sensor 2, the object detection sensor 2 can be arranged at a position that takes into account the wavelength characteristics of the ultrasonic waves without providing a separate member. In this way, the position of the object detection sensor 2 relative to the sensor holding unit 3 can be adjusted with a simple configuration, and an unnecessary position adjustment mechanism can be prevented from being provided.

  Further, the distance g between the distal end of the pivot support part 34 and the bracket side fixing part 32a is configured to have the same length as the plate thickness t of the extension part 22, so that the object detection sensor 2 and the sensor holding part 3 are configured. In the assembled state, the extension portion 22 can be sandwiched and fixed between the bracket side fixing portion 32a and the pivot support portion 34 (see FIG. 6B).

  Furthermore, in the pivoting state in which the object detection sensor 2 pivots toward the assembled state with the sensor holding unit 3, the pocket 32 that surrounds the extending part 22 and the bracket side fixing part 32 a is provided. Since the pocket 32 can prevent the extension part 22 and the bracket side fixing part 32a from interfering with other parts in the assembled state, an external force acts on the extension part 22 and the bracket side fixing part 32a, It is possible to prevent the extension portion 22 and the bracket side fixing portion 32a from being released.

  Further, even if the extension portion 22 and the bracket-side fixing portion 32a are fixed, the pocket 32 can receive and hold the extension portion 22 and the bracket-side fixing portion 32a. It is possible to prevent the detection sensor 2 from falling.

  Furthermore, since the extension part 22 can guide along the pocket 32 when the extension part 22 pivots on the surrounding body, the recess part 25 can be reliably guided and fitted to the protrusion part 33. Thereby, the object detection sensor 2 and the sensor holding | maintenance part 3 can be fixed reliably.

  Further, with respect to the pivot support portion 34, the fixing portion 23 and the fixing screw receiving portion 35 are provided on the side opposite to the side where the extending portion 22 and the bracket side fixing portion 32a are disposed (+ H direction side). That is, the extension 22 and the bracket side fixing part 32a are arranged on one side with respect to the pivot support part 34, and the fixing part 23 and the fixing screw receiving part 35 are arranged on the other side. Both one side (lower side) and the other side (upper side) with respect to the moving support part 34 can be fixed, and the object detection sensor 2 and the sensor holding part 3 can be fixed more firmly.

  Furthermore, as shown in FIG. 7, when the fixing portion 23 and the fixing screw receiving portion 35 are fixed by screwing a screw or the like to the pivot direction side of the object detection sensor 2 that pivots toward the assembled state, Specifically, the concave portion disposed on the opposite side via the pivot support portion 34 by screwing the fixing portion 23 and the fixing screw receiving portion 35 with screws or the like and fixing them to the pivot direction side. A force acts on 25 and the concave portion 25 and the convex portion 33 can be more firmly fixed.

  Two extending portions 22 and bracket-side fixing portions 32a are provided at both ends in the width direction on the lower end side, and the fixing portion 23 and the fixing screw receiving portion 35 are provided with two extending portions 22 and the bracket-side fixing portion 32a. Since the object detection sensor 2 and the sensor holding unit 3 can be fixed at three points, the rotation of the two axes can be prevented, and the object detection sensor 2 The sensor holding unit 3 can be stably fixed and can be prevented from being displaced.

  In addition, in the assembled state, the locking piece 36 for temporarily fixing the object detection sensor 2 and the sensor holding portion 3 by pivoting is provided, so that the fixing portion 23 is sandwiched in the width direction and temporarily fixed. it can. Thereby, since the fixing part 23 and the fixing screw receiving part 35 can be temporarily fixed at the position where the object detection sensor 2 and the sensor holding part 3 are accurately positioned, the fixing part 23 and the fixing screw receiving part 35 can be easily fixed.

Although the temporary fixing portion corresponds to the locking piece 36, the present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

  For example, in the present embodiment, the pivot fixing portion corresponds to the extending portion 22 and the bracket side fixing portion 32a, but the fixing portion 23 is a protrusion and the fixing screw receiving portion 35 is a recess. These convex portions and concave portions may be fixed by pivoting the object detection sensor 2.

  As described above, the pivot fixing portion may be disposed at a position where the fixing portion 23 is disposed, or the locking piece 36 corresponding to the temporary fixing portion may correspond to the pivot fixing portion. In these cases, the extension portion 22 and the bracket side fixing portion 32a may not be provided.

  In other words, in the present embodiment, as a means for fixing the object detection sensor 2 and the sensor holding unit 3, the convex portion 33 and the concave portion 25, and the fixing portion 23 and the fixing screw receiving portion 35 are fixed at two locations. However, the object detection sensor 2 and the sensor holding unit 3 may be fixed by using one of them as a pivot fixing unit.

  In the present embodiment, the extending portion 22 is pivotally supported by the pivot support portion 34, but the pivot support portion 34 may pivotally support the device main body 21. In this case, the pivot fixing portion may be provided in the device main body 21 supported by the pivot support portion 34. However, the object detection sensor 2 is pivoted using the pivot support portion 34 supporting the device main body 21 as a pivot axis. If it can be fixed by moving, it may be provided in another place. That is, the position pivotally supported by the pivot support part 34 does not necessarily have to be a part of the extension part 22 and may be an end part of the apparatus main body.

  Furthermore, in the present embodiment, the pivot support portion 34 has a flat plate shape, but the shape is not limited as long as a part of the object detection sensor 2 can be pivotably supported. A through hole capable of locking the pivot support portion 34 formed in a claw shape may be provided in the protruding portion 22.

  In this case, the object detection sensor 2 can be easily pivoted with respect to the sensor holding unit 3 and the pivot support position can be easily fixed at a predetermined location, so that the protrusion 33 and the recess 25 can be more securely fitted. While being easily performed, the object detection sensor 2 and the sensor holding part 3 can be locked by the pivot support part 34 even if the fitting part is damaged.
