  As described in Patent Document 1, in the case where an attachment component is fixed to an adherend surface such as a bumper using an adhesive member, in order to maintain the adhesiveness of the adhesive member before the fixing, For reasons such as easy handling, the adhesive member is generally covered with release paper.

  However, in the case of an attachment part for attaching the vehicle part to the vehicle, it is necessary to securely fix the automobile part even if it receives vibrations when the vehicle travels. Therefore, it is necessary to use an adhesive member having a considerably strong adhesive force. As a result, considerable stress acts on the adhesive member when the release paper is peeled from the adhesive member.

  On the other hand, since the fixing portion provided with the adhesive member is required to be flexibly deformed in accordance with the shape of the surface to be bonded such as a bumper, the forming material of the fixing portion is a flexible material that is easily deformable. Used. Therefore, for example, when an operator tries to peel off the release paper from the adhesive member by holding the sensor support part and picking the end of the release paper on the tip side of the fixed part opposite to the support part. The fixing portion is strongly bent in the peeling direction of the release paper. As a result, the fixing part (or support part) is distorted in the bending direction (plastic deformation), and the workability when attaching to the non-adhesive surface is deteriorated, or in some cases, the fixing part (or support part) is damaged. As a result, there may be a problem that sufficient attachment strength cannot be secured.

  The present invention has been made in view of the above-described points, and is an attachment component capable of preventing deformation and damage of the sticking portion when the release paper is peeled from the sticking portion on which the adhesive material is formed. The purpose is to provide.

In order to achieve the above object, the mounting component according to the present invention is for mounting the component on a vehicle,
A holding part (21) for holding parts;
A plurality of affixing parts (26) having an affixing surface (26a) extending from the periphery of the holding part and having an adhesive material formed on the surface thereof, and affixing the affixing surface to the affixed surface of the vehicle to which the parts are to be attached. And comprising
Before the affixing part is affixed to the vehicle, a release paper (30) that covers the formation area of the adhesive material on the affixing surface is affixed to the affixing surface,
A grip part (29) where no adhesive material is formed is provided at the tip of the sticking part far from the holding part so that the sticking part can be held when peeling the release paper.

  Thus, in this invention, the holding part in which the adhesive material is not formed is provided in the front-end | tip of the sticking part. For this reason, the operator can peel the release paper from the adhesive material while gripping the grip portion. As a result, when the release paper is peeled off, it is possible to prevent the sticking portion from being greatly deformed even if stress is applied to the sticking portion. Therefore, deformation and damage of the sticking part can be prevented.

  In the above-described configuration, the release paper can cover all the formation region of the adhesive material on the application surfaces of the plurality of application parts with one sheet, and the gripping part is at least one of the plurality of application parts. It may be provided in one sticking part. Covering all of the adhesive material formation areas on the application surfaces of a plurality of application parts with a single release paper, compared to the case where each adhesive material formation area is covered with an individual release paper. The release paper can be efficiently peeled off. Further, when the release paper is peeled off, a large stress acts in the direction of peeling the release paper at the sticking portion at the start of the peeling. Therefore, since it is sufficient to prevent deformation due to stress acting at the start of peeling, the gripping portion only needs to be provided on at least one pasting portion among the plurality of pasting portions.

  The reference numerals in the parentheses merely show an example of a correspondence relationship with a specific configuration in an embodiment described later in order to facilitate understanding of the present invention, and are intended to limit the scope of the present invention. Not intended.

  Hereinafter, embodiments of a mounting part according to the present invention will be described with reference to the drawings. In the present embodiment, an ultrasonic sensor for detecting obstacles around the vehicle is used as a vehicle component, and a retainer that is a mounting component for mounting the ultrasonic sensor on the back surface of a bumper of the vehicle will be described.

  First, the ultrasonic sensor 1 will be described with reference to FIG. The ultrasonic sensor 1 is, for example, a transmission / reception type that oscillates a piezoelectric ceramic vibrator by a piezoelectric effect to emit ultrasonic waves, and converts ultrasonic vibrations incident on the piezoelectric ceramic vibrator into electric signals. . As shown in FIG. 1, the ultrasonic sensor 1 includes a sensor main body 11, a casing 12, and the like.

  The sensor body 11 is formed in a stepped cylindrical shape having a tip 11a (lower end) having a minimum diameter. A microphone incorporating a piezoelectric ceramic vibrator is incorporated in the distal end portion 11 a of the sensor body 11.

  The casing 12 is connected to the sensor body 11 and is formed to have a size that includes the sensor body 11 in plan view. The casing unit 12 emits ultrasonic waves from the microphone, or when the ultrasonic waves are incident on the microphones, processes the electrical signals generated by the ultrasonic waves to detect reception of the ultrasonic waves. The control board which performs is accommodated. A connection terminal portion 13 to which one end of a cable for connection to an external device (not shown) is connected is provided on one side surface 12a of the housing portion 12. An ultrasonic transmission / reception result is transmitted from the ultrasonic sensor 1 to the external device via the cable.

  Moreover, the arm part 14 extended toward the downward direction is provided in the side surfaces 12b and 12c of the housing | casing part 12 adjacent to the side surface 12a in which the connection terminal part 13 was provided, respectively. The arm portion 14 is formed with an engagement through hole 14a. When the ultrasonic sensor 1 is attached to the retainer 2, the engagement through hole 14 a engages with the tapered protrusion 22 of the retainer 2 and prevents the ultrasonic sensor 1 from falling off the retainer 2. The retainer 2 may be provided with an engagement through hole, and the ultrasonic sensor 1 may be provided with a tapered protrusion that engages with the engagement through hole.

  Further, a groove is formed in the arm portion 14 so as to be fitted to the protrusion 23 protruding from the upper end surface of the retainer 2. When the tapered protrusion 22 of the retainer 2 is engaged with the engagement through hole 14a of the arm portion 14, at the same time, the protrusion 23 is fitted into the groove inside the arm portion 14, so that the ultrasonic sensor 1 is Rotation around the central axis can be prevented.

  When the ultrasonic sensor 1 is attached to the retainer 2, the upper end surface of the retainer main body 21 of the retainer 2 comes into contact with the lower end surface of the housing portion 12, and the housing portion 12 of the ultrasonic sensor 1 is moved. To support.

  Next, the retainer 2 will be described in detail with reference to FIGS. 2 is a plan view of the retainer 2, FIG. 3 is a side view of the retainer 2 as seen from the direction of arrow A in FIG. 2, FIG. 4 is a side view of the retainer 2 as seen from the direction of arrow B in FIG. FIG. Here, in FIG. 2 to FIG. 4, the retainer 2 in a state where the release paper 30 is attached is shown. On the other hand, in FIG. 5, the release paper 30 is not shown in order to show the state of the lower surface of the retainer 2.

  The retainer 2 is formed of a resin material such as polybutylene terephthalate (PBT) or polycarbonate-polybutylene terephthalate (PCPBT) from the viewpoint of obtaining necessary dimensional accuracy and strength and having flexibility. Is done. The retainer 2 has a cylindrical retainer body 21 that supports and fixes the ultrasonic sensor 1 with a tapered protrusion 22 and a protrusion 23 and an upper end surface thereof, while the sensor body 11 is inserted. At the lower end of the retainer main body 21, a ring-shaped base portion 24 having a larger diameter than the retainer main body 21 is provided.

  And the some sticking part 26 is connected to the side surface of the base 24 via the some connection part 25 (In the example shown in FIG. 1, the number of the sticking parts 26 is eight). The connecting portion 25 is narrower than the lateral width of the sticking portion 26 so that the sticking portion 26 easily deforms following the shape of the bumper 3. And the connection part 25 is continued to the sticking part 26 in the center position of the lateral width of the sticking part 26.

  Each sticking portion 26 has a sticking surface 26 a to be attached to the bumper 3 on the bottom surface. A plurality of grooves 26b are formed on the upper surface opposite to the affixing surface 26a. As shown in FIG. 2, two groove portions 26 b are formed in the lateral width direction in the pasting portion 26 excluding the pair of pasting portions 26 from which the connecting portion 25 extends from directly below the tapered protrusion 22. Further, in the pair of pasting portions 26 in which the connecting portion 25 extends from directly below the taper-shaped protrusion 22, with respect to two sides extending in parallel with the substantially trapezoidal pasting portion 26 near the center in the lateral width direction of the pasting portion 26. One groove portion 26b1 is formed in the orthogonal direction, and two groove portions 26b2 extending in the lateral width direction are formed on both sides of the one groove portion 26b1.

  The site | part in which groove part 26b, 26b1, 26b2 was formed is thin compared with the other site | part of the sticking part 26 in which groove part 26b, 26b1, 26b2 is not formed. For this reason, the sticking part 26 is easy to bend in the front and back direction of the drawing paper with the groove parts 26b, 26b1, 26b2 as the bending center. Thereby, the followable | trackability to the shape of the bumper 3 of the sticking part 26 can be improved. The formation positions of the groove portions 26b, 26b1, 26b2 are not limited to the example shown in FIG. 2, and any position can be adopted as long as the followability of the sticking portion 26 to the shape of the bumper 3 can be improved.

  As shown in FIG. 5, each of the pasting surfaces 26 a of the plurality of pasting portions 26 has a substantially trapezoidal shape. Thereby, the clearance gap between the adjacent sticking parts 26 can be made small, and it becomes easy to ensure the area of the sticking surface 26a enough.

  Double-sided tape 27 is affixed to each of the plurality of affixing surfaces 26a. As shown in FIG. 5, the double-sided tape 27 has a trapezoidal shape similar to the shape of each pasting surface 26a. For this reason, the double-sided tape 27 can be provided so as to cover the most area of each sticking surface 26a, and a sufficient sticking area can be obtained. In addition, the double-sided tape 27 has a sufficiently strong adhesive strength so that the double-sided tape 27 does not fall off the bumper 3 even when it receives vibrations when the vehicle travels.

  Then, the retainer 2 is fixed to the inner side surface 3 a of the bumper 3 by pasting the double-sided tape 27 on the pasting surface 26 a of the plurality of pasting portions 26 to a predetermined position on the inner side surface (back side) 3 a of the bumper 3. At this time, since the sticking portion 26 has sufficient flexibility, even if the inner side surface 3a of the bumper 3 is formed in a curved shape, it can be deformed so as to follow the shape.

  The bumper 3 is formed with a bumper hole 3b that penetrates the bumper 3 and into which the tip end portion 11a of the sensor body 11 is inserted. The retainer 2 is fixed to the inner surface 3a of the bumper 3 so that the retainer main body 21 surrounds the bumper hole 3b. Thereby, when the ultrasonic sensor 1 is fixed to the retainer 2, the tip end portion 11 a of the sensor main body 11 is exposed to the surface side of the bumper 3.

  Here, in the case where the double-sided tape 27 is applied to the plurality of application surfaces 26a and the application part 26 is applied to the inner surface 3a of the bumper 3, the adhesiveness of the double-sided tape 27 is not deteriorated until immediately before the application, The double-sided tape 27 is covered with the release paper 30 for reasons such as making the retainer 2 easy to handle.

  As shown in FIGS. 2 to 4, the release paper 30 can cover all the formation area of the double-sided tape 27 on the application surfaces 26 a of the application parts 26 with one sheet. When all the formation area of the double-sided tape 27 on the application surface 26a of the plurality of application parts 26 is covered with a single release paper 30, the formation area of each double-sided tape 27 is covered with individual release paper. Compared to the above, the peeling operation of the release paper 30 can be performed efficiently.

  Furthermore, when the release paper 30 covers the entire area where the double-sided tape 27 is formed on the application surfaces 26a of the plurality of application parts 26 with one sheet, the peripheral edge of the release paper 30 is more than the tip of the application part 26. Has a size that protrudes outward. Thereby, when an operator performs the operation | work which peels the release paper 30, it becomes easy to pick the peripheral part of the release paper 30, and workability | operativity can be improved.

  However, as described above, the plurality of connecting portions 25 and the pasting portions 26 are formed so as to be easily deformable so as to follow the shape of the inner side surface 3 a of the bumper 3. Therefore, for example, when the operator holds the retainer main body 21 and grips the end of the release paper 30 protruding from the front end side of the sticking portion 26 and tries to peel the release paper 30 from the double-sided tape 27, The affixing portion 26 receives a strong force in the peeling direction of the release paper 30. As a result, the connecting portion 25 and the sticking portion 26 are distorted in the bending direction, and workability when attaching to the non-adhesive surface is deteriorated. There is a risk that inadequate attachment strength cannot be secured.

  Therefore, in the present embodiment, as shown in each drawing, in one affixing part 26 among the affixing parts 26, a grip part 28 on which the double-sided tape 27 is not formed is provided at the tip of the affixing part 26. That is, the grip portion 28 is provided continuously to the tip of the sticking portion 26 and has a sufficient area for the operator to grip. Accordingly, when the operator performs the peeling operation of the release paper 30, even if a force for bending the application portion 26 is applied by the release paper 30, the operator holds the holding portion 28, thereby the application portion 26. Can be prevented from being greatly deformed. Therefore, the deformation | transformation and damage of the sticking part 26 and the connection part 25 can be prevented.

  Further, the grip portion 28 is provided to be bent with respect to the pasting surface 26 a of the pasting portion 26 so as to be separated from the release paper 30. As a result, a sufficient gap is opened between the grip portion 28 and the release paper 30, so that an operator can easily grip the end portion of the release paper 30 or grip the grip portion 28. it can. As a result, the operator can efficiently perform the peeling operation of the release paper 30.

  In the present embodiment, as described above, the release paper 30 that can cover all the formation area of the double-sided tape 27 on the application surfaces 26a of the application parts 26 with one sheet is used. In this case, at the initial stage when the release paper 30 is peeled off, the largest stress acts in the direction of peeling the release paper at the sticking portion 26. Therefore, if the deformation due to the stress acting at the start of peeling is prevented, it is sufficient to prevent the deformation and damage of the connecting portion 25 and the pasting portion 26. Therefore, the grip portion 28 is one of the plural pasting portions 26. It is only necessary to provide at the sticking part 26.

  In this embodiment, as shown in FIG. 2 and FIG. 5, in addition to the pasting portion 26 provided with the gripping portion 28, the remaining three pasting portions 26 positioned at the four corners of the release paper 30 are also pasting portions 26. A substantially triangular extension 29 is provided on the distal end side. As shown in FIG. 5, the double-sided tape 27 is not formed on the lower surface of the extension portion 29. The main role of the extension part 29 is to give the retainer 2 the appearance-like characteristics. That is, since the shape of the bumper 3 varies depending on the type of vehicle, the shape of the sticking portion 26 and the formation position of the groove portion 26b may be varied in accordance with the shape of the bumper 3. In such a case, an appearance feature is provided so that it can be determined at a glance which type of vehicle retainer 2 is used. Therefore, a certain retainer 2 may not have the extension part 29 at all, may have only one extension part 29, or may have two extension parts 29 or three extension parts 29. . Further, as a feature on the appearance, a through hole 29a formed in the extension portion 29 can be used.

  However, since the double-sided tape 27 is not formed on the lower surface of the extension portion 29 described above, the extension portion 29 can be used as a gripping portion for holding the sticking portion 26 when the release paper 30 is peeled off.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. Is.

  For example, in the above-described embodiment, the example in which the width of the connecting portion 25 is narrower than the lateral width of the pasting portion 26 has been described. However, the width of the connecting portion 25 may be the same as the lateral width of the attaching portion 26 on the connecting portion 25 side. Further, the two sides of the trapezoidal sticking portion 26 narrowed in a square shape may be extended to the base portion 24 as they are.

  In the embodiment described above, eight pasting portions 26 are provided, but the number of pasting portions 26 is not limited to eight. Moreover, the shape of the sticking part 26 is good also as shapes other than trapezoid shape.

  In the embodiment described above, the retainer 2 for attaching the ultrasonic sensor 1 to the bumper 3 of the vehicle has been described. However, the present invention is used to fix other vehicle parts to other parts of the vehicle. May be.
