Description

[Technical Field]

[0001] The present invention relates to a sensor mounting member for mounting a sensor on an exterior body of a vehicle. [Background technology]

[0002] Conventionally, automobile bumpers are equipped with sensors that detect the surrounding environment using ultrasonic waves or the like. The sensor is attached to the bumper by passing it through a small hole formed in the bumper from the back side of the bumper. At this time, the sensor is fixed to the back side of the bumper using a mounting member equipped with adhesive tape or the like. For example, the ultrasonic sensor described in Patent Document 1 below (hereinafter referred to as the "Publication 1 Invention") has a mounting base attached to the back side of the bumper with the sensor attached to it. Initially, the sensor protrudes from the mounting base, and when the mounting base is attached to the bumper, the sensor is positioned by passing it through the hole. The sensor that protrudes from the hole is finally pushed into the mounting base until it does not protrude beyond the edge of the hole and is then accommodated therein. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5984081 Summary of the Invention [Problem to be solved by the invention]

[0004] As mentioned above, in the invention of the first prior art document, the mounting base is attached to the bumper, and then the sensor is pushed into the mounting base. Therefore, the force exerted when the sensor is pushed acts in a direction that causes the mounting base to peel off from the bumper. Therefore, there is a possibility that the mounting base may peel off from the bumper together with the sensor and fall off.

[0005] The present invention has been proposed in light of the above circumstances. It is an object of the present invention to provide a sensor mounting member that is easy to position on the exterior body of a vehicle and that prevents the sensor from falling off when mounted. In a broader sense, the present invention aims to promote the advancement of ADAS by appropriately grasping the situation around the vehicle and ensuring safety, which is a universal issue. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the sensor mounting member of the present invention comprises a bracket that is inserted from the inside of the exterior body into a hole formed in the exterior body of a vehicle to mount a sensor, and a holder that holds the sensor and is combined with the bracket and attached to the back surface of the exterior body, and is characterized in that the bracket is inserted into the hole with the bracket previously engaged with the holder, and from a temporary fixed state in which the holder faces the back surface of the exterior body with a gap, the holder approaches the bracket and is attached to the back surface of the exterior body, and the holder engages with the bracket to reach an attached state.

[0007] The sensor mounting member of the present invention is characterized in that the bracket has a claw portion, and the claw portion has a state change control portion that contacts the holder in the temporarily fixed state and prevents the holder from approaching the bracket.

[0008] The sensor mounting member according to the present invention is characterized in that the bracket has a claw portion, and the claw portion has an engaging portion that engages with the holder in the mounted state.

[0009] The sensor mounting member according to the present invention is characterized in that the bracket has a bracket position restricting portion that abuts against the rear surface of the exterior body.

[0010] The sensor mounting member according to the present invention is characterized in that the bracket has a guide portion that guides the holder from the temporarily fixed state to the mounted state.

[0011] The sensor mounting member of the present invention is characterized in that the holder has an opening through which the sensor is passed and an attachment portion that extends from the periphery of the opening toward the opposite side of the opening from the outer casing and has an open tip at the end of the extension, and the sensor is passed through the opening from the tip side of the attachment portion and attached to the attachment portion.

[0012] The sensor mounting member of the present invention is characterized in that the bracket has a ring-shaped bracket main body portion, the claw portion extends from the bracket main body portion on the opposite side of the bracket main body portion from the outer casing, the state change regulating portion is formed at the tip of the claw portion, the engaging portion is formed on the claw portion between the state change regulating portion and the bracket main body portion, the holder has an opening through which the sensor is passed, the regulating portion against which the state change regulating portion abuts is formed on the side of the opening facing the outer casing, and the engaging portion with which the engaging portion engages is formed on the side of the opening opposite the regulating portion. [Effects of the Invention]

[0013] The sensor mounting member according to the present invention includes a bracket that is inserted from the inside of a hole formed in the exterior body of a vehicle to mount a sensor, and a holder that holds the sensor and is attached to the rear surface of the exterior body when combined with the bracket. The bracket is inserted into the hole with the bracket already engaged with the holder, and the holder moves from a temporary attachment state in which the bracket faces the rear surface of the exterior body with a gap between them to an attached state in which the holder approaches the bracket and is attached to the rear surface of the exterior body and engages with the bracket. In other words, in the temporary attachment state, there is a gap between the holder and the rear surface of the exterior body, and the holder is not attached to the rear surface of the exterior body, making it easy to position the bracket relative to the hole. After the bracket is positioned, the holder and the bracket are combined, and the holder is attached to the rear surface of the exterior body at the same time, thereby fixing the position of the holder. The external force required to attach the sensor mounting member to the exterior body acts on the sensor mounting member, and no load is applied to the sensor, preventing the sensor from falling off during installation.

[0014] In the sensor mounting member according to the present invention, the bracket has a claw portion, and the claw portion has a state change restricting portion that abuts against the holder in a temporarily fastened state to restrict the holder from approaching the bracket. In the temporarily fastened state, the holder abuts against the state change restricting portion, so that the holder is retained in a position spaced apart from the rear surface of the exterior body relative to the bracket inserted into the hole, allowing the bracket to be positioned before the holder adheres to the rear surface of the exterior body. This makes it easy to position the bracket relative to the hole.

[0015] In the sensor mounting member according to the present invention, the bracket has a claw portion, and the claw portion has an engaging portion that engages with the holder in the mounted state. In the mounted state, the holder is attached to the rear surface of the exterior body, and the claw portion engages with the engaging portion, thereby engaging the holder with the bracket, so that the bracket is fixed in the position where it was temporarily positioned. Therefore, the bracket and the sensor will not fall off when the sensor is mounted.

[0016] In the sensor mounting member according to the present invention, the bracket has a bracket position restricting portion that abuts against the rear surface of the exterior body. That is, in the temporarily fastened state, the bracket position restricting portion abuts against the rear surface of the exterior body, making it easy to position the bracket relative to the hole.

[0017] In the sensor mounting member according to the present invention, the bracket has a guide portion that guides the holder from the temporary fastening state to the mounted state. Because the holder is guided by the guide portion, the bracket does not come off the holder in the temporary fastening state or the mounted state. Furthermore, because the holder moves while being guided by the guide portion, the holder is reliably guided until it engages with the bracket, and the holder does not slip off the back surface of the exterior body when attached.

[0018] In the sensor mounting member according to the present invention, the holder has an opening through which the sensor passes and an attachment portion that extends from the periphery of the opening toward the opposite side of the exterior body relative to the opening and has an open tip, and the sensor is passed through the opening from the tip side of the attachment portion and attached to the attachment portion. In addition to a configuration in which the sensor is attached to the holder in advance and the sensor mounting member is attached to the exterior body, another configuration is also realized in which the sensor is attached to the holder from the end of the attachment portion after the sensor mounting member is attached to the exterior body. This allows the sensor attachment procedure to be selected according to the situation, simplifying the work.

[0019] In the sensor mounting member according to the present invention, the bracket has an annular bracket main body, a claw portion extends from the bracket main body on a side opposite the exterior body relative to the bracket main body, a state-change restricting portion is formed at the tip of the claw portion, an engaging portion is formed in the claw portion between the state-change restricting portion and the bracket main body, the holder has an opening through which the sensor is passed, a restricting receiving portion with which the state-change restricting portion abuts is formed on the side of the opening facing the exterior body, and an engaging receiving portion with which the engaging portion engages is formed on the side of the opening opposite the restricting receiving portion. The state-change restricting portion of the bracket abuts on the restricting receiving portion of the holder, thereby maintaining a provisionally fastened state, and the engaging portion of the bracket engaging with the engaging receiving portion of the holder, thereby ensuring a robust mounting state.

DETAILED DESCRIPTION OF THE INVENTION

[0021] A sensor-mounting member according to an embodiment of the present invention will now be described with reference to the drawings. Figures 1 and 2 show the sensor-mounting member 1 according to this embodiment in use, attached to a bumper 2 as the exterior body of a vehicle. Figure 1 shows the sensor-mounting member 1 in use as viewed from the outside of the bumper 2, and Figure 2 shows the sensor-mounting member 1 in use as viewed from the inside of the bumper 2. Figures 3 and 4 show the sensor-mounting member 1 disassembled. Vehicles for which the present invention can be used include, for example, automobiles, trains, ships, and aircraft. In this embodiment, the vehicle is an automobile.

[0022] As shown in Figures 1 and 2, a circular hole 3 for mounting a sensor (not shown) is formed in the bumper 2, and the sensor mounting member 1 is used to mount the sensor on the bumper 2. The sensor is, for example, an ultrasonic sensor such as a sonar. A sonar generates and transmits ultrasonic waves using a piezoelectric element such as a ceramic or single crystal, and receives the waves reflected by objects around the bumper to detect the presence or absence of the object and the distance from the vehicle to the object.

[0023] In the following, the direction in which the sensor mounting member 1 is attached to the bumper 2, from the inside to the outside of the bumper 2, is referred to as the forward direction (Front), the direction from the outside to the inside of the bumper 2 is referred to as the rearward direction (Back), and the directions perpendicular to the front-to-rear direction are referred to as the upper, lower, left and right directions, respectively (Up, Down, Left, Right).

[0024] The front end of the sensor mounting member 1 is inserted into the hole 3 from the inside of the bumper 2 and is positioned on the edge of the hole 3 in a position that does not protrude forward from the hole 3. The sensor is attached to the sensor mounting member 1 in a position that does not protrude from the front end of the sensor mounting member 1, and therefore does not protrude from the hole 3 either. Therefore, the sensor mounting member 1 and the sensor are positioned flush with the outer surface of the bumper 2 or in a position slightly recessed from the outer surface of the bumper 2.

[0025] 1 to 4, the sensor mounting member 1 has a bracket 4 and a holder 15. The bracket 4 is inserted into the hole 3 of the bumper 2, and the holder 15 holds the sensor and is attached to the rear surface of the bumper 2 together with the bracket 4.

[0026] The bracket 4 and the holder 15 will be described below with reference to the drawings. Figures 5 to 12 show the appearance and cross section of the bracket 4, and Figures 13 to 22 show the appearance and cross section of the holder 15.

[0027] 3 to 14, the bracket 4 has a circular bracket main body 5, four claws 6 extending rearward from the bracket main body 5 on the opposite side of the bracket main body 5 from the bumper 2, and a pair of guides 10 extending rearward from the bracket main body 5. The guides 10 are longer than the claws 6. The claws 6 and the guides 10 are located at different positions on the periphery of the bracket main body 5.

[0028] The claw portions 6 are arranged at appropriate intervals on all four sides along the periphery of the bracket main body 5. The claw portions 6 extend linearly rearward from the edge of the bracket main body 5. A state change restricting portion 8 is formed at the tip of the claw portion 6, and an engaging portion 9 is formed between the state change restricting portion 8 and the bracket main body 5 of the claw portion 6. Specifically, a protruding portion 7 that protrudes outward is formed at the tip of the claw portion 6. The protruding portion 7 on the tip side of the claw portion 6 is the state change restricting portion 8, and the opposing side of the protruding portion 7 from the state change restricting portion 8 is the engaging portion 9. The state change restricting portion 8 is an inclined surface that gradually protrudes outward from the tip of the claw portion 6 toward the bracket main body 5. The engaging portion 9 is a step formed by the protruding portion 7.

[0029] The guide portions 10 are arranged at intervals of approximately 180° along the periphery of the bracket main body 5. The guide portions 10 are approximately L-shaped portions formed on the outer surface of the bracket main body 5. Specifically, the guide portion 10 has a guide base 11 that protrudes outward from the bracket main body 5, and a guide rail portion 12 that extends rearward from the tip of the guide base 11. A bracket position restricting portion 13 is formed on the guide base 11. Specifically, the bracket position restricting portion 13 is a flat surface formed on the front end of the guide base 11. A guide slit 14 is formed in the guide rail portion 12. The guide slit 14 is a linear gap that is formed over the entire length of the guide rail portion 12 and is closed at the guide base 11 and the tip.

[0030] 13 to 20, the holder 15 has an opening 16 through which the sensor passes, an attachment portion 17 extending rearward from the periphery of the opening 16 on the opposite side of the opening 16 from the bumper 2, a pair of base portions 18 extending left and right from the periphery of the opening 16, and a pair of guide receiving portions 19 formed between the opening 16 and the base portions 18. The inside of the opening 16 is hollow, and a circular insertion hole 20 is formed therein.

[0031] The mounting portion 17 has a pair of sensor holding pieces 21 to which a sensor is attached, and the tip end of the mounting portion 17 is open between the sensor holding pieces 21. Therefore, the insertion hole portion 20 is open from front to back.

[0032] The base portion 18 is thin and generally rectangular. An adhesive sheet (not shown) is attached to the front surface of the base portion 18. The left and right base portions 18 are each divided into an upper and lower portion. Specifically, the upper first base portion 22 extends laterally from an upper portion around the periphery of the opening 16, and the lower second base portion 23 extends laterally from a lower portion around the periphery of the opening 16. A gap is formed between the first base portion 22 and the second base portion 23, and a base gap 24 is formed between each portion 22, 23.

[0033] As shown in FIG. 21 , the guide receiving portion 19 is formed on the left and right sides of the periphery of the opening 16 at the boundary between the opening 16 and the base portion 18. The guide receiving portion 19 has a guide groove portion 25 formed on the outer peripheral edge of the opening 16, a guide auxiliary portion 26 extending rearward from the guide groove portion 25, a guide protrusion 27 formed in part of the guide auxiliary portion 26, and a guide hole portion 28 formed between the guide groove portion 25 and the base portion 18. The guide groove portion 25 is formed between a pair of groove-forming protrusions 29 protruding from the outer surface of the opening 16. The guide auxiliary portion 26 has a linear rod shape. The guide protrusion 27 is located in the front portion of the guide auxiliary portion 26, midway between the groove-forming protrusions 29, and protrudes outward. The guide hole portion 28 is connected to the base gap 24.

[0034] 22, a restriction receiving portion 30 is formed on the front edge of the opening 16, which is the side facing the bumper 2, and an engagement receiving portion 31 is formed on the rear side, which is the opposite side of the restriction receiving portion 30. The restriction receiving portion 30 and the engagement receiving portion 31 are connected in the front-to-rear direction. The restriction receiving portion 30 is a groove formed on the inner peripheral edge of the opening 16, and the engagement receiving portion 31 is a hole that communicates with the outer surface of the opening 16.

[0035] The bracket 4 and holder 15 are configured as described above. Next, the operation of the sensor mounting member 1 will be explained with reference to the drawings, along with its functions and effects. Figures 23 to 28 show the sensor mounting member 1 attached to the bumper 2. Figures 23 to 25 show the sensor mounting member 1 in a temporarily attached state, and Figures 26 to 28 show the sensor mounting member 1 in an attached state.

[0036] 23 to 25, in the temporarily fastened state, the bracket 4 of the sensor mounting member 1 is already fastened to the holder. Also, in the temporarily fastened state, the bracket is inserted into the hole 3 of the bumper 2, and the base portion 18 of the holder faces the back surface of the bumper 2 with a gap therebetween.

[0037] Before the sensor mounting member 1 is attached to the bumper 2, the bracket 4 is first attached to the holder 15 from the front of the holder 15. Specifically, the guide portion 10 of the bracket 4 is attached to the guide receiving portion 19 of the holder 15 (see FIGS. 3 and 4 ). The guide rail portion 12 of the guide portion 10 is inserted into the guide hole portion 28 of the guide receiving portion 19 while being guided by the guide groove portion 25. As the guide rail portion 12 continues to be inserted, the guide rail portion 12 climbs over the guide protrusion 27 of the guide receiving portion 19. At the same time, the guide protrusion 27 passes through the guide slit 14 of the guide rail portion 12. In this manner, with the guide portion 10 and the guide receiving portion 19 engaged, the bracket 4 and the holder 15 can move relatively forward and backward. At this time, the guide rail portion 12, sandwiched between the guide groove portion 25, moves along the guide auxiliary portion 26 of the guide receiving portion 19, allowing the bracket 4 and the holder 15 to move linearly and stably.

[0038] In the temporarily fastened state, when the bracket 4 and the holder 15 are at their farthest apart, the claw portion 6 of the bracket 4 abuts against the opening 16 of the holder 15. Specifically, the state change restricting portion 8 of the claw portion 6 abuts against the restriction receiving portion 30 of the opening 16. This restricts the holder 15 from approaching the bracket 4, and the temporarily fastened state is maintained.

[0039] When the temporarily fixed sensor mounting member 1 is inserted into the hole 3 of the bumper 2, the bracket main body 5 is positioned at the center of the hole 3, and the slight gap between the bracket main body 5 and the inner peripheral surface of the hole 3 is aligned evenly around the circumference. Note that a jig (not shown) can also be used to position the bracket main body 5 relative to the hole 3.

[0040] When the sensor mounting member 1 in the temporarily fastened state is inserted into the hole 3 of the bumper 2, the guide portion 10 of the bracket 4 abuts against the back surface of the bumper 2. Specifically, the bracket position restricting portion 13 of the guide portion 10 abuts against the back surface of the bumper 2. Therefore, the bracket 4 does not overhang excessively from the bumper 2, making it easy to position the bracket 4 relative to the hole 3. Furthermore, in the temporarily fastened state, there is a gap between the base portion 18 of the holder 15 and the back surface of the bumper 2, and the holder 15 is not attached to the back surface of the bumper 2, so it is possible to position the bracket 4 before the holder 15 is attached to the back surface of the bumper 2. Therefore, it is easy to position the bracket 4 relative to the hole 3.

[0041] When the holder 15 is pushed forward in the temporarily fastened state, the sensor mounting member 1 changes to the mounted state. From the temporarily fastened state to the mounted state, the guide portion 10 of the bracket 4 is guided by the guide receiving portion 19 of the holder 15, so the bracket 4 will not come off the holder 15 in either the temporarily fastened state or the mounted state. Furthermore, the external force required to mount the sensor mounting member 1 to the bumper 2 acts on the sensor mounting member 1, and no load is placed on the sensor, so the sensor will not fall off when mounted.

[0042] 26 to 28, in the mounted state, the sensor mounting member 1 is in a state in which the holder 15 approaches the bracket 4 and is engaged with the bracket 4. Also, in the mounted state, the base portion 18 is attached to the back surface of the bumper 2 via an adhesive sheet. That is, after the bracket 4 is positioned, the holder 15 and the bracket 4 are combined and at the same time the holder 15 is attached to the back surface of the bumper 2, thereby fixing the position of the holder 15. Because the bracket 4 is already fixed in the position where it has been positioned, the bracket 4 and the sensor will not fall off when the sensor is mounted.

[0043] In the attached state, the claw portion 6 of the bracket 4 climbs over the opening 16 of the holder 15 and engages with the opening 16. Specifically, the engagement portion 9 of the claw portion 6 engages with the engagement receiving portion 31 of the opening 16. Therefore, the attached state is robust.

[0044] The timing at which the sensor is attached to the sensor mounting member 1 is arbitrary. Therefore, in addition to a mode in which the sensor is attached to the holder 15 beforehand and then the sensor mounting member 1 is attached to the bumper 2, there is also a mode in which the sensor is attached to the bumper 2, and then the sensor is passed through the opening 16 from the end of the attachment portion 17 (rear in FIG. 2) and attached to the holder 15. Therefore, the procedure for attaching the sensor can be selected according to the situation, making the work easy.

[0045] In other embodiments of the present invention, the state change restricting portion and the engaging portion are formed separately on the bracket, and therefore, this embodiment has, for example, a claw portion that is formed with only the state change restricting portion and no engaging portion, or a claw portion that is formed with only the engaging portion and no state change restricting portion. Another embodiment has a state change restricting portion but does not have an engaging portion. Another embodiment has an engaging portion and does not have a state change restricting portion. In other embodiments, the number of claws and the number of guides of the bracket are arbitrary. Thus, the number of claws is 2, 3, 5 or more. The number of guides is 3 or more. In another embodiment, the bracket position restricting portion of the bracket is formed separately from the guide portion. In another embodiment, the bracket does not have a bracket position restriction portion. In another embodiment, the bracket does not have a guide portion and the holder does not have a guide receiving portion. In another embodiment, the tip of the mounting portion is closed instead of open. In this case, the sensor mounting member is attached to the bumper with the sensor already attached to the holder.

[0046] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various design modifications can be made to the present invention without departing from the scope of the claims.
