Description

  The present invention relates to a retainer for mounting a sensor used when a sensor such as an ultrasonic sensor is mounted inside a part constituting a body surface such as a bumper so as to be exposed to the outside from a hole of a part constituting the body surface such as a bumper. .

  Conventionally, a retainer used when a sensor (for example, an ultrasonic sensor or the like) is attached to the inside of a part constituting a body surface such as a bumper is used to follow various curvatures of a part constituting a body surface such as a bumper. A technique is disclosed (for example, Patent Document 1).

  In Patent Document 1, a sticking portion that extends from the retainer main body that holds the sensor and is fixed to the inner side surface of the bumper is branched at the tip portion, or a groove that intersects the sticking portion within the inner side surface of the bumper is formed. It is easy to bend by providing. Therefore, the followability of the retainer (sticking portion) to the inner surface of the bumper is improved, and the retainer can be prevented from being peeled off or displaced due to poor followability.

JP2013-221880A

  By the way, the affixing part of the retainer is in a state without bending before being fixed to the inner side surface of the bumper or the like, and is bent and pressed by being pressed against the inner side surface of the bumper or the like with a jig. And fixed by an adhesive member (double-sided tape or the like). Therefore, when the retainer is fixed to the inner surface of a bumper or the like having a certain degree of curvature (when the affixing portion is pressed), the tip side of the affixing portion first comes into contact with the inner surface of the bumper or the like, and the affixing is performed according to the deflection of the affixing portion The base end side (retainer main body side) of the portion also comes into contact. That is, the attaching portion of the retainer starts to be fixed (adhered) from the distal end side, and then the proximal end side is also fixed (adhered) in accordance with the bending due to the pressing.

  However, even if the followability of the retainer (sticking part) is improved as in Patent Document 1, in the configuration in which the fixing (adhesion) from the tip side of the sticking part to the inner surface of the bumper or the like is started, Among them, there is a possibility that the mounting strength at the base end side portion becomes weak. That is, when fixing (adhering) the affixing portion, in order to adhere the proximal end portion of the affixing portion to the inner surface of the bumper or the like, the affixing portion needs to be bent along the curvature of the bumper or the like. Yes, there is a possibility that the pressure for bonding the proximal end portion is insufficient due to the influence of the repulsive force or the like when the sticking portion is bent. In addition to adhesive members (such as double-sided tape) provided at the affixing part, when applying adhesive to the inner surface of a bumper, etc., press the affixing part against the inner surface of the bumper, etc. Even if it tries to spread, there is a possibility that it will not spread to the portion on the proximal end side of the sticking part due to insufficient press. Therefore, for example, when a force is applied to the sensor through a hole such as a bumper, the sensor may be peeled off together with the retainer, or the position of the sensor with respect to the bumper may change.

In order to solve the above problem, in one embodiment, the sensor mounting retainer is:

Represents. Further, the bumper 30 may be a front bumper of the vehicle or a rear bumper.

  The sensor 10 is, for example, an ultrasonic sensor, which emits an ultrasonic wave by vibrating a piezoelectric element such as PZT (lead zirconate titanate) by a piezoelectric effect, and an ultrasonic wave (reflected wave) incident on the piezoelectric element. It converts the vibration caused by the noise into an electrical signal and detects obstacles around the vehicle. The sensor 10 includes a sensor main body 11, a housing part 12, a connection terminal part 13, a mounting part 14, and the like.

  The sensor body 11 includes an ultrasonic microphone formed of a piezoelectric element, an aluminum case, and the like, and has a substantially cylindrical shape. The sensor 10 exposes the lower end surface of the sensor main body 11 in the drawing from the hole 31 of the bumper 30 to the outside of the bumper 30, transmits ultrasonic waves from the lower end surface, and receives reflected waves, thereby It is configured to be able to detect obstacles.

  The casing 12 has a size that includes the sensor main body 11 when viewed from the central axis direction of the cylindrical shape of the sensor main body 11, detects a reflected wave (ultrasonic wave) received from a booster circuit that drives a piezoelectric element. It contains a receiving circuit, a filler for protecting the circuit and the like for waterproofing.

  The connection terminal portion 13 is a connector for electrically connecting to an external device.

  Note that the sensor 10 is connected to, for example, an ECU (Electric Control Unit) that controls the sensor 10 via a connection line (such as a direct line or a communication line) connected to the connection terminal unit 13 and is received by the ECU. An electrical signal corresponding to the reflected wave may be transmitted. Then, the ECU may calculate the time from transmission of the ultrasonic wave to reception based on the received electrical signal, and may calculate the distance from the sensor 10 to the obstacle around the vehicle based on the calculated time. Further, the ECU may determine the possibility of collision with the obstacle based on the calculated distance to the obstacle. When it is determined that the possibility of collision is high, an intervention braking request (instruction for generating braking force by intervention), torque limitation, and the brake ECU that controls the braking device of the vehicle and the engine ECU that controls the engine, respectively. A request (instruction to reduce the engine output) may be output. As described above, the sensor 10 may be applied to driving assistance for avoiding a collision with an obstacle around the vehicle.

  The attachment portion 14 is provided to fix the sensor 10 to the retainer 1 and has two attachment portions 14a and 14b. The attachment portions 14a and 14b are provided so as to face each other with the sensor main body 11 and the housing portion 12 interposed therebetween. Further, the attachment portion 14 includes an insertion portion 15, an attachment hole 16, and the like.

  The insertion portion 15 includes two insertion portions 15a and 15b corresponding to the two attachment portions 14a and 14b, respectively, and is configured such that wall portions 6a and 6b of the retainer 1 described later can be inserted.

  The mounting hole 16 includes two mounting holes 16a and 16b corresponding to the two mounting portions 14a and 14b, respectively. With the sensor 10 mounted on the retainer 1, the mounting holes 16 of the retainer 1 have a wall portion 6a and 6b. Engage with the engaging protrusions 6Ca and 6Cb provided on each.

  In the perspective views of FIGS. 1 and 2, the mounting hole 16 b is not shown and is not shown.

  The retainer 1 is formed of a resin material (for example, polybutyne terephthalate or the like), and includes a retainer main body 2, a pasting portion 3, a hold portion 4, and the like.

  The retainer body 2 includes a bottom portion 5, a wall portion 6, and the like, and has a function of holding the sensor 10. Specifically, each of two opposing wall portions 6 (6a, 6b) erected corresponding to two opposing sides of the substantially square bottom portion 5 serving as a base is attached to the mounting portions 14a, 14b ( The sensor 10 is attached to the retainer body by being inserted into the insertion portions 15a and 15b). Thereby, positioning of the sensor 10 in the direction where wall part 6a, 6b opposes can be performed.

  Further, the walls 6a and 6b are formed with recesses 6A (6Aa and 6Ab), 6B (6Ba and 6Bb), engaging protrusions 6C (6Ca and 6Cb), and the like, thereby fixing the position of the sensor 10. .

  The concave portions 6Aa and 6Ab are provided on the outer surfaces of the wall portions 6a and 6b, respectively, and have a function of guiding convex portions (not shown) provided on the inner surfaces of the insertion portions 15a and 15b when the sensor 10 is attached to the retainer 1. . Moreover, it has the function to position the sensor 10 in the said direction by restrict | limiting the movement of the sensor 10 to the direction along two sides of the bottom part 5 corresponding to standing wall part 6a, 6b.

  The recesses 6Ba and 6Bb are provided on the inner surfaces of the walls 6a and 6b, respectively, and correspond to the projections (not shown) provided on the inner surfaces of the insertion portions 15a and 15b when the sensor 10 is attached to the retainer (recesses 6Aa and 6Ab). Different from the convex portion to be guided). Moreover, it has the function to position the sensor 10 in the said direction by restrict | limiting the movement of the sensor 10 to the direction along two sides of the bottom part 5 corresponding to standing wall part 6a, 6b.

  The engagement protrusions 6Ca and 6Cb engage with the mounting holes 16a and 16b of the sensor 10 when a predetermined amount of the wall portions 6a and 6b of the retainer 1 is inserted into the insertion portions 15a and 15b of the sensor 10, respectively. Thereby, the positioning of the sensor 10 in the reference axis CL direction is performed, and the sensor 10 is attached (fixed) to the retainer 1.

  Since the wall portions 6a and 6b are liable to tilt in the direction in which they approach each other due to the shrinkage in the cooling process at the time of molding the retainer 1, the positioning of the sensor 10 by the concave portions 6A, the concave portions 6B, the engaging projections 6C, etc. It may be performed at a portion close to the base of the portions 6a and 6b.

  Further, an insertion hole 7 is provided in the bottom portion 5 of the retainer body 2, and the tip portion (lower end portion in the drawing) of the sensor body 11 is inserted into the insertion hole 7 in a state where the sensor 10 is attached to the retainer 1. It is arranged so as to protrude below the bottom 5. Thereby, from the viewpoint of appearance when the sensor 10 (the front end portion of the sensor main body 11) is viewed from the outside of the bumper 30, the sensor 10 is configured so that the front end surface of the sensor main body 11 is substantially flush with the surface of the bumper 30. Can be arranged.

  The affixing part 3 includes affixing parts 3a and 3b extending substantially on the same plane as the bottom part 5 from the two opposite sides of the bottom part 5 where the wall parts 6a and 6b are not provided. Has a shape. Adhesive members 9 (for example, double-sided tape or the like), which will be described later, are attached to the lower surfaces of the pasting portions 3a and 3b, and are pasted (attached) to the inner side surface of the bumper 30.

  Moreover, the sticking parts 3a and 3b are each provided with a groove-like stress relaxation part 8 on the upper surface. The stress relaxation part 8 includes stress relaxation parts 8a and 8b corresponding to the sticking parts 3a and 3b. The stress relaxation parts 8a and 8b are attached to, for example, the inner side surface of the bumper 30 where the sticking parts 3a and 3b have a certain degree of curvature. When it is done, the followability to the bumper 30 is improved by making it easy to bend. In addition, the function of the retainer main body 2 that positions the sensor 10 is not impaired by suppressing the deformation of the wall 6 (6a, 6b) of the retainer main body 2 due to the influence of the bending of the attaching portions 3a and 3b. Can be.

  The holding part 4 is provided at the tip of the sticking part 3, and, as will be described later, in the step of attaching the retainer 1 to the bumper 30, the hold part 4 comes into contact with the inner surface of the bumper 30 before the tip of the sticking part 3. It has the function to make the sticking part 3 act the support force of the direction away from the inner surface. The hold unit 4 includes hold units 4a and 4b corresponding to the pasting units 3a and 3b, respectively. The hold part 4a includes two hold parts 4a1, 4a2 provided near both ends of one side of the tip part of the sticking part 3a. The hold parts 4a1, 4a2 extend from the sticking part 3a by a predetermined amount in the extending direction. Then, it has a substantially L shape bent downward. Similarly, the hold part 4b includes two hold parts 4b1 and 4b2 provided near both ends of one side of the tip part of the sticking part 3b. The hold parts 4b1 and 4b2 extend from the sticking part 3b by a predetermined amount in the extending direction. It has a substantially L-shape bent downward at the protruding portion. That is, the L-shaped tips (lower ends) of the holding portions 4a and 4b are located further below the lower surfaces of the pasting portions 3a and 3b to which the adhesive members 9a and 9b are attached.

  Next, the process of attaching the retainer 1 according to this embodiment to the bumper 30 will be described.

  FIG. 3 is a diagram illustrating a process of attaching the retainer 1 according to the present embodiment to the bumper 30. Specifically, the side view is viewed from a direction orthogonal to the extending direction of the attaching portions 3a and 3b of the retainer 1. It is sectional drawing. FIG. 3A shows a state before the retainer 1 contacts the inner side surface of the bumper 30, and FIG. 3B shows a state after the retainer 1 contacts the inner side surface of the bumper 30.

  In addition, the adhesion member 9 (9a, 9b) is attached to the lower surface of the sticking parts 3a, 3b. Further, an adhesive is additionally applied to the position where the adhesive portions 3a and 3b on the inner surface of the bumper 30 are fixed, and the entire lower surfaces of the adhesive portions 3a and 3b are pressed by pressing on the upper surfaces of the adhesive portions 3a and 3b described later. To be spread.

  As shown in FIG. 3A, the step of attaching the retainer 1 to the bumper 30 is performed with the positioning jig 40 attached to the retainer 1 instead of the sensor 10.

  As with the sensor 10, the positioning jig 40 is attached to the retainer 1 so that its tip end is positioned below the lower surfaces of the pasting portions 3a and 3b. The positioning jig 40 has a substantially cylindrical shape whose outer diameter is slightly larger than the hole 31 of the bumper 30, and at least its distal end portion has a tapered shape (tapered shape). It is formed smaller than the inner diameter of the hole 31 of the bumper 30. That is, the positioning jig 40 comes into contact with the inner peripheral surface of the hole 31 when a predetermined amount of the positioning jig 40 is inserted in the direction of the center axis (reference axis CL) of the hole 31 of the bumper 30. Then, the central axis of the positioning jig 40 that substitutes the central axis of the sensor main body 11 and the central axis of the hole 31 of the bumper 30 are in agreement.

  Like the sensor 10, the positioning jig 40 has a mounting structure in which the wall portions 6a and 6b of the retainer 1 can be inserted, and moves upward (away from the retainer 1 along the central axis of the insertion hole 7 of the retainer 1). Movement in the direction) is possible. Therefore, with the positioning jig 40 attached to the retainer 1, the tip of the positioning jig 40 is brought into contact with the inner peripheral surface of the hole 31 of the bumper 30, and the retainer 1 is further moved downward in that state. The retainer 1 can be positioned by sticking to the inner surface of the bumper 30.

  3B shows a state in which the retainer 1 is further moved downward in a state where the tip end portion of the positioning jig 40 is in contact with the inner peripheral surface of the hole 31 of the bumper 30, and the retainer 1 is moved to the inner surface of the bumper 30. The contact state is shown. Here, in order to affix the affixing parts 3a and 3b to the inner surface of the bumper 30, the pressing jig 50 presses the affixing parts 3a and 3b from the upper surface side.

  The pressing jig 50 is formed so that the outer end thereof is positioned on the inner side of the tips of the attaching portions 3a and 3b when the attaching portions 3a and 3b are pressed from the upper surface side. Thereby, when it presses from the upper surface side of sticking part 3a, 3b so that it may mention later, the hold part 4 can be plastically deformed from the root.

  Since the retainer 1 has L-shaped holding portions 4a and 4b at the tip portions of the sticking portions 3a and 3b, as shown in FIG. 3B, the retainer 1 is more than the lower surface (adhesive member 9) of the sticking portions 3a and 3b. First, the hold portions 4 a and 4 b come into contact with the inner surface of the bumper 30.

  Thereafter, the pressing portions 50 a and 3 b are bent by the pressing by the pressing jig 50, and the portion closer to the retainer main body 2 (the base end side) approaches the inner side surface of the bumper 30. On the other hand, the tip portions of the sticking portions 3a and 3b can hardly approach the inner surface of the bumper 30 due to the action of the holding portions 4a and 4b. For this reason, of the adhesive members 9 a and 9 b attached to the lower surfaces of the pasting portions 3 a and 3 b, the portion closer to the retainer body 2 (the base end side) comes into contact with the inner surface of the bumper 30 first.

  Thereafter, when the pressing to the sticking portions 3a and 3b by the pressing jig 50 is further advanced, the non-pressed hold portions 4a and 4b are at the root, that is, in the vicinity of the connection portion between the hold portions 4a and 4b and the sticking portions 3a and 3b. Causes plastic deformation. Thereby, among the adhesive members 9a and 9b attached to the lower surfaces of the pasting portions 3a and 3b, the tip side portion also contacts the inner side surface of the bumper 30. In addition, it is possible to eliminate the reaction force for peeling the retainer 1 by the holding portions 4a and 4b after the retainer 1 is attached to the inner side surface of the bumper 30.

  The strength of the holding portions 4a and 4b is such that the portion of the adhesive members 9a and 9b closer to the retainer body 2 comes into contact with the inner surface of the bumper 30 when the pressing jig 50 presses the pasting portions 3a and 3b. It may be appropriately designed so as to be plastically deformed at a predetermined timing after the sticking is started.

  Thus, the retainer 1 according to the present embodiment is attached to a predetermined position on the inner surface of the bumper 30.

  Next, the operation of the retainer 1 according to the present embodiment will be described by comparison with a retainer 1c according to a comparative example as a conventional technique.

  The retainer 1c according to the comparative example is the same as the retainer 1 except that the hold unit 4 is not provided. In the following description regarding the retainer 1c, the same portions as the retainer 1 will be described using the same reference numerals.

  FIG. 4 is a diagram for explaining a process of attaching the retainer 1c according to the comparative example to the bumper 30. Specifically, as in FIG. 3, from the direction orthogonal to the extending direction of the attaching portions 3a and 3b of the retainer 1c. FIG. 4A shows a state before the retainer 1c contacts the inner surface of the bumper 30, and FIG. 4B shows a state after the retainer 1c contacts the bumper 30. FIG.

  As in the case of the retainer 1 (FIG. 3), the adhesive member 9 (9a, 9b) is attached to the lower surfaces of the pasting portions 3a, 3b. In addition, an adhesive is additionally applied to the position where the affixing portions 3a and 3b on the inner side surface of the bumper 30 are fixed. Can be spread.

  As shown in FIG. 4A, the step of attaching the retainer 1c to the bumper 30 is performed by attaching the positioning jig 40 to the retainer 1 instead of the sensor 10 as in the case of the retainer 1 (FIG. 3A). Done in state. Since the operation of the positioning jig 40 is the same, the description thereof is omitted.

  FIG. 4B shows a state in which the retainer 1 c is further moved downward with the tip of the positioning jig 40 in contact with the inner peripheral surface of the hole 31 of the bumper 30, so that the retainer 1 c is moved to the inner surface of the bumper 30. The contact state is shown. Here, in order to affix the affixing parts 3a and 3b to the inner surface of the bumper 30, the pressing jig 50 presses the affixing parts 3a and 3b from the upper surface side.

  Since the bumper 30 has a certain degree of curvature, as shown in FIG. 4 (b), the retainer 1 is located on the tip side of the adhesive members 9 a and 9 b attached to the lower surfaces of the pasting portions 3 a and 3 b. The contact is started, and sticking is started.

  Thereafter, the pressing portions 50 a and 3 b are bent by the pressing by the pressing jig 50, and the portion closer to the retainer main body 2 (the base end side) approaches the inner side surface of the bumper 30. Of the adhesive members 9 a and 9 b attached to the lower surfaces of the pasting portions 3 a and 3 b, the portion closer to the retainer body 2 (the base end side) also contacts the inner side surface of the bumper 30.

  That is, in the process of attaching the retainer 1c according to the comparative example to the bumper 30, the application is started from the tip side portions of the application portions 3a and 3b, and close to the retainer body 2 according to the bending of the application portions 3a and 3b due to the pressing. The side (base end side) part is also affixed. For this reason, in the pasting portions 3a and 3b, there is a possibility that the pressing on the portion closer to the retainer main body 2 (the base end side) is insufficient than the portion on the distal end side. In addition, there is a possibility that the adhesive applied to the inner side surface of the bumper 30 is not sufficiently spread on the portion of the lower surface of the sticking portions 3a and 3b on the retainer body 2 side. As a result, the attachment strength of the portion close to the retainer main body 2 (base end side) of the lower surfaces of the pasting portions 3a and 3b becomes insufficient, or the portion close to the retainer main body 2 (base end side) There is a possibility of floating from the inner surface of the bumper 30.

  As described above, if the portion of the lower surface of the attaching portions 3a and 3b on the side close to the retainer main body 2 (base end side) is insufficiently attached, force is applied to the sensor 10 from the outside of the bumper 30 through the hole 31. In such a case, the sensor 10 may be peeled off together with the retainer 1, or the position of the sensor 10 may be shifted from a predetermined position.

  On the other hand, in the step of attaching the retainer 1 according to the present embodiment to the bumper 30, as described above, the pasting is started from the portion of the pasting portions 3a and 3b closer to the retainer main body 2 and the plastic deformation of the holding portion 4 is performed. Later, the tip side part is attached. Therefore, there is no shortage of pressing to the portion (base end side) close to the retainer main body 2 in the pasting portions 3a and 3b, and the adhesive applied to the inner surface of the bumper 30 also reaches the lower surface of the portion. It is pushed out. In addition, after the plastic deformation of the holding part 4, the distal end side of the sticking parts 3a and 3b can also be sufficiently pressed. As a result, it is possible to sufficiently secure the attachment strength of the whole sticking parts 3a and 3b. .

  Therefore, by using the retainer 1 according to this embodiment, when a force is applied to the sensor 10 from the outside of the bumper 30 through the hole 31, the sensor 10 is peeled off together with the retainer 1, or the sensor 10 is displaced from a predetermined position. Can be difficult. That is, the retainer 1 according to the present embodiment can further improve the attachment strength when fixed to the bumper 30 having a certain degree of curvature.

  As mentioned above, although the form for implementing this invention was explained in full detail, this invention is not limited to this specific embodiment, In the range of the summary of this invention described in the claim, various Can be modified or changed.

  For example, in the above-described embodiment, the retainer 1 is provided for attaching the sensor 10 to the bumper 30, but may be provided for attaching the sensor 10 to a portion constituting another body surface such as a grill portion. . That is, the retainer 1 according to the present embodiment is configured so that the sensor 10 is exposed to the body surface side through a hole formed in the portion constituting the body surface of the vehicle. It may be attached inside.
