Description

  The present invention relates to a mounting structure of a side collision detection sensor, and in particular, a sealed space is formed by an outer panel of a vehicle side door and a resin resin panel provided closer to the passenger compartment than the outer panel. The present invention relates to a mounting structure for a side collision detection sensor that detects a side collision (including a collision from an oblique direction with respect to a longitudinal direction of a vehicle) by detecting a pressure in the space.

  Conventionally, a vehicle is provided with an occupant protection device such as a seat built-in airbag or a curtain airbag. When another vehicle collides with a side door, the collision is detected and the occupant protection device is activated. It is like that. As an example of such an occupant protection device, Japanese Patent Application Laid-Open No. H10-228561 discloses an air pressure that detects the pressure in the internal space formed between the outer panel and the inner panel of the side door in order to detect a collision with the side door. A sensor provided with a sensor (side collision detection sensor) is known. In this apparatus, when another vehicle or the like collides with the side door, the air pressure in the internal space rises. Therefore, the air pressure sensor detects the pressure fluctuation of the air pressure in the internal space and determines the collision.

JP-A-8-324379

In such an inner space of the side door, a regulator and a motor for driving the window glass protruding and protruding from between the outer panel and the inner panel in the vertical direction, a speaker, and the like are housed. These components are arranged on a panel separate from the inner panel, and the air pressure sensor described above needs to be attached to this panel. An opening to which the panel is attached is formed in the inner panel, and the panel is fixed so as to close the opening.
By the way, when such a panel is made of resin, the rigidity is lower than that of a metal inner panel. Therefore, when attaching the above components, it is necessary to ensure attachment strength. In particular, since the pressure sensor used for detecting the side collision of the vehicle and operating the occupant protection device must operate reliably at the time of the collision, it is very important to secure the mounting strength.

  The objective of this invention is providing the attachment structure of the side collision attachment sensor which can ensure the attachment intensity | strength when attaching a side collision detection sensor to a resin panel.

  In order to achieve the above object, the present invention provides a sealed space formed by an outer panel of a vehicle side door and a resin resin panel provided closer to the vehicle compartment than the outer panel. A mounting structure of a side collision detection sensor that detects a side collision by detecting pressure, and the resin panel so that the pressure detection part of the side collision detection sensor mounted on the surface of the resin panel on the vehicle interior side communicates with the sealed space An opening formed on the vehicle exterior side, a flange formed so as to protrude outwardly from at least the upper periphery of the opening on the outer surface of the resin panel, and a vehicle compartment side of the resin panel on which the flange is formed And a fixing portion for fixing the side collision detection sensor formed on the surface.

  In this invention comprised in this way, a side collision detection sensor is attached to the resin panel by being fixed to the surface by the side of the resin panel of a resin panel. Through the opening formed in the resin panel, the pressure detection part of the side collision detection sensor communicates with the sealed space formed by the outer panel and the resin panel, and the side collision detection sensor can detect the pressure in the sealed space. Become. At this time, since the collar portion is formed so as to protrude outwardly from at least the upper periphery of the opening on the outer surface of the resin panel, water or the like entering from the gap between the outer panel and the resin panel Intrusion into the pressure detection part of the side collision sensor is prevented.

  According to the mounting structure of the side collision detection sensor according to the present invention, the flange portion is provided so as to protrude outward from at least the upper part of the opening on the vehicle outer surface of the resin panel. Water can be prevented from entering the pressure detection part of the sensor. Therefore, failure of the side collision detection sensor can be prevented and detection performance can be maintained. Moreover, since it forms so that it may protrude in the vehicle outward direction from the at least upper part periphery of the opening part of the vehicle outer surface of a resin panel, the resin panel around an opening part can be reinforced with a collar part. Therefore, the structure for attaching the side collision detection sensor to the resin panel becomes stronger. Since the rigidity of the resin panel around the opening is increased by the flange, it is difficult to form a gap between the resin panel and the side collision detection sensor, so that the sealing performance of the side collision detection sensor is improved. Furthermore, since the fixing portion is provided on the resin panel, the side collision detection sensor can be reliably fixed to the resin panel. At this time, since the fixing portion protrudes from the resin panel side, there is no need to form the fixing portion on the side collision detection sensor side, and a hole or the like for receiving the fixing portion from the side collision detection sensor side is formed in the resin panel. Since it is not necessary, the waterproofness of the mounting structure of the side collision detection sensor can be secured satisfactorily.

In the present invention, preferably, the fixing portion is formed so as to extend from the region between the collar portion and the opening to the vehicle compartment side on the surface of the resin panel on the vehicle compartment side.
In the present invention configured as described above, the fixing portion extends from the region between the flange portion and the opening portion on the surface of the resin panel on the passenger compartment side where the rigidity is reinforced by the flange portion to the passenger compartment side. Thus, the rigidity of the base end of the fixed portion can be further strengthened.

In the present invention, preferably, the fixed portion is a claw portion extending toward the vehicle compartment side along the side collision detection sensor, and a front end of the claw portion on the vehicle compartment side is engaged with a vehicle compartment side portion of the side collision detection sensor. Thus, the side collision detection sensor is formed to be fixed.
In the present invention configured as described above, since the fixing portion is the claw portion, the side collision detection sensor can be fixed by engaging the claw portion with the compartment side portion of the side collision detection sensor. Therefore, for example, since it is not necessary to form the insertion part, the engaging part, or the like into which the claw part is inserted in the side collision detection sensor, the structure of the side collision detection sensor can be simplified.

In the present invention, preferably, the side collision detection sensor is formed with a protrusion having a screw fixing hole extending along a surface of the resin panel on the vehicle interior side, and is formed at a position of the resin panel corresponding to the screw fixing hole. A boss hole protrusion that protrudes to the outside of the vehicle is formed, and a boss hole is formed in the boss hole protrusion from the surface of the resin panel on the passenger compartment side, and a bolt is inserted into the boss hole through the screw fixing hole. The boss hole protrusion is formed so as to be connected to the flange.
In the present invention configured as described above, the side collision sensor has a protrusion having a screw fixing hole and the resin panel has a boss hole. Therefore, in addition to fixing by the fixing portion, side collision detection is performed. The sensor can be fixed to the resin panel with a bolt. Therefore, the structure for attaching the bump detection sensor to the resin panel is further strengthened by the bolt inserted through the side impact screw fixing hole and inserted into the boss hole. Further, since the boss hole is formed in the boss hole protrusion, the rigidity around the boss hole can be increased, and the fixing force of the side collision detection sensor by the bolt can be further increased. Furthermore, since the protrusion part for boss holes is connected with the collar part, the rigidity improvement of the resin panel can be further promoted by the collar part and the protrusion part for the boss hole.

And a wire 45 connected to the upper end portion of the movable member 42 and having the other end inserted into the guide rail 41 from the lower end side and connected to the lower end portion of the movable member 42. .
When the motor 43 is actuated, the movable member 42 moves up and down along the guide rail 41 via the pulley 44 and the wire 45, so that the window glass 14 moves up and down.
Below the sealed space 12, an impact bar 15 that receives the impact force of the collision from the side of the vehicle body extends in the vehicle front-rear direction, and is fixed to the outer surface of the inner panel 6 at both ends thereof.

  As shown in FIG. 1, the vehicle 1 is provided with an airbag device (curtain airbag device) 50 having an airbag that can be deployed along the inner surface of the window glass 14.

  Next, the side collision detection sensor mounting structure according to the present embodiment will be described with reference to FIGS. FIG. 3 is a partial perspective view of a resin panel showing a mounting structure of a side collision detection sensor according to an embodiment of the present invention as viewed from the outside of the vehicle, and FIG. 4 is a mounting structure of a side collision detection sensor according to an embodiment of the present invention. FIG. 5 is a partial side view of the resin panel showing the mounting structure of the side collision detection sensor according to one embodiment of the present invention as seen from the vehicle exterior side. 6 is a partial side view of a resin panel showing a mounting structure of a side collision detection sensor according to an embodiment of the present invention as seen from the vehicle compartment side, and FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. FIG. 8 is a sectional view taken along line VIII-VIII in FIG.

The side collision detection sensor 60 is formed in a substantially rectangular parallelepiped shape, and is arranged so that the longitudinal direction is along the vertical direction of the resin panel 8. The side collision detection sensor 60 is, for example, a semiconductor pressure sensor, and includes a pressure detection unit in which a part of an elastic body made of single crystal silicon is formed in a thin plate shape and diffusion piezoresistors are arranged at four locations on the surface thereof. It is housed and configured in a container. In addition, as a side collision detection sensor, not only the thing of the above structures but the arbitrary detection system and a shape are employable.
A pressure introducing portion 62 for introducing air pressure to the pressure detecting portion is formed on one side surface of the side collision detection sensor 60, and this side surface is arranged facing the surface of the resin panel 8 on the vehicle compartment side. A connection part 64 for connecting the pressure detection part to the control unit 51 is attached to the lower surface of the side collision detection sensor 60.

  As shown in FIGS. 3 and 5, the pressure introducing portion 62 is an opening formed inside a substantially trapezoidal outer edge 62 </ b> A protruding from the side surface of the side collision detection sensor 60. In the resin panel 8, an opening 19 having substantially the same shape as the outer edge 62 </ b> A is formed at a position corresponding to the pressure introducing portion 62. The outer edge 62A passes through the opening 19 and protrudes to the opposite side, whereby the pressure introducing part 62 opens into the sealed space 12, and the pressure detecting part and the sealed space 12 are separated by the opening 19 and the pressure introducing part 62. Communicated. A seal member 65 is provided on the outer side of the outer edge 62 </ b> A of the pressure introducing portion 62, and this seal member 65 is disposed between the resin panel 8 and the side collision detection sensor 60. The seal member 65 seals a space between the surface of the resin panel 8 on the vehicle compartment side and the surface of the side collision detection sensor 60, and prevents water from entering the pressure detection unit from the surface of the resin panel 8 on the vehicle compartment side. it can.

  On the surface of the resin panel 8 on the vehicle outer side (sealed space 12 side), a flange 20 for preventing water from above from entering the pressure introducing portion 62 is formed above the pressure introducing portion 62. The flange portion 20 is formed in a substantially semicircular shape so as to protrude upward, and covers the upper periphery (approximately upper half) of the opening surface of the pressure introducing portion 62. In addition, the flange portion 20 protrudes at a substantially right angle with respect to the surface of the resin panel 8 and is formed in a substantially L-shaped cross section together with the surface of the resin panel 8. As shown in FIG. 7, the protruding dimension L <b> 1 of the flange part 20 is larger than the dimension L <b> 2 at which the outer edge 62 </ b> A protrudes from the outer surface of the resin panel 8.

  Cylindrical boss hole protrusions 22 are formed at both ends of the flange 20, and both ends of the flange 20 are connected to the boss hole protrusions 22, respectively. The central axis of the boss hole protrusion 22 is disposed substantially perpendicular to the plane of the resin panel 8. A boss hole 24 for attaching the side collision detection sensor 60 is formed at a position corresponding to the boss hole protrusion 22 on the surface of the resin panel 8 on the passenger compartment side. These boss holes 24 are formed to the inside of the boss hole protrusions 22 toward the inside of the boss hole protrusions 22, and screws are formed on the inner surfaces. The central axis of the boss hole 24 coincides with the central axis of the boss hole protrusion 22. Here, the boss hole 24 does not penetrate the boss hole protrusion 22 and does not open into the sealed space 12. Accordingly, it is possible to prevent water from entering the side collision detection sensor 60 side from the sealed space 12 through the boss hole 24.

  In the side collision detection sensor 60, protrusions 63 are formed on both side surfaces adjacent to the side surface on which the pressure introducing portion 62 is provided. These protrusions 63 extend in a substantially horizontal direction along the surface of the resin panel 8 on the passenger compartment side, and have screw fixing holes 66 on the front end side. These screw fixing holes 66 are arranged at positions corresponding to the boss hole protrusions 22 of the flange 20, that is, positions corresponding to the boss holes 24. The side collision detection sensor 60 is fixed to the resin panel 8 by inserting the bolts 28 into the boss holes 24 and screwing them through the screw fixing holes 66.

A claw portion 26 as a fixing portion for fixing the side collision detection sensor 60 to the resin panel 8 is formed integrally with the resin panel 8 on the surface of the resin panel 8 on the passenger compartment side. A plurality (four in this embodiment) of claw portions 26 are provided so as to protrude from the surface of the resin panel 8 on the passenger compartment side. Two of these claw portions 26 are arranged on both sides of the side collision detection sensor 60 and above the projection 63, and the other two are arranged on both sides of the side collision detection sensor 60 and below the projection 63. The The distance between the two sets of claws 26 facing in the lateral direction of the resin panel 8 is set to be approximately the same as the lateral dimension of the side collision detection sensor 60.
The tip of the claw portion 26 protrudes inward toward the side collision detection sensor 60. The front ends of these claw portions 26 are engaged with the rear surface (outer surface) of the side collision detection sensor 60 which is a compartment side, thereby pressing the side collision detection sensor 60 against the resin panel 8 side. A certain amount of crushing is used to ensure good water resistance.

  When attaching the side collision detection sensor 60 to the resin panel 8, the pressure introduction part 62 is inserted in accordance with the position of the opening 19. Since the claw portion 26 is made of resin and has flexibility, when the side collision detection sensor 60 enters between the opposing claw portions 26, the claw portion 26 is removed while being in contact with the side surface of the side collision detection sensor 60. Bend in the direction. When the side collision detection sensor 60 is further pressed against the resin panel 8, when the tip of the claw portion 26 moves to the vehicle compartment side with respect to the side collision detection sensor 60, the claw portion 26 returns inward, and the rear surface of the side collision detection sensor 60. And the side collision detection sensor 60 is held. Thereafter, the side collision detection sensor 60 is fixed to the resin panel 8 by inserting the bolts 28 from the screw fixing holes 66 of the protrusions 63 and screwing them into the boss holes 24.

  In the present embodiment, in a state where the side collision detection sensor 60 is attached to the resin panel 8, the inner surface (opposing surface) of the claw portion 26 facing in the lateral direction contacts the side surface of the side collision detection sensor 60. Or with a slight spacing. Therefore, the claw portion 26 functions as a left / right direction restricting portion that restricts the side collision detection sensor 60 from moving in the left / right (lateral) direction. In the present embodiment, the lower surface of the upper claw portion 26 is in contact with the upper surface of the protrusion 63 or is disposed with a slight interval. The upper surface of the lower claw portion 26 is disposed in contact with the lower surface of the protrusion 63 or with a slight interval. Therefore, the claw portion 26 functions as a vertical direction restricting portion that restricts the side collision detection sensor 60 from moving in the vertical direction. Furthermore, the lower two of these claw portions 26 function as support portions that support the protrusion 63 from below even if the bolt 28 of the protrusion 63 is removed.

  Here, as shown in FIGS. 5 and 6, the upper two base ends of the claw portions 26 are regions between the flange portion 20 and the opening portion 62 (opening portion 19), that is, the flange portion 20 and And located in a substantially semicircular region surrounded by a virtual line connecting the lower ends of the boss hole protrusions 22 on both sides. The lower two of the claw portions 26 are not located in the region between the flange portion 20 and the opening portion 62, but are disposed in the vicinity of the boss hole protruding portion 22, and two in the lateral direction. It arrange | positions rather than the protrusion part 22 for boss holes.

  In the vehicle 1 having such a configuration, when another vehicle or the like collides sideways with the side door 2 and the outer panel 4 is deformed to be recessed toward the passenger compartment, the air pressure in the sealed space 12 of the side door 2 fluctuates. . The control unit 51 monitors the pressure change of the air pressure in the sealed space 12 detected by the side collision detection sensor 60, and determines that a side collision has occurred when the pressure change becomes a predetermined value or more. The control unit 51 outputs an operation signal to the operation mechanism of the airbag device 50, and the airbag device 50 is activated and deployed along the inner surface of the window glass 14.

According to the present embodiment configured as described above, the following excellent effects can be obtained.
Since the opening portion 19 is formed in the resin panel 8, the pressure detection portion and the sealed space 12 are connected to the opening portion 19 and the opening portion 62 while the side collision detection sensor 60 is disposed on the surface of the resin panel 8 on the vehicle interior side. Can communicate with each other. Here, in the present embodiment, for example, when the window glass 14 is lowered to the lowest position, water may enter the sealed space 12 from between the outer panel 4 and the inner panel 6. In the side collision detection sensor mounting structure of the present embodiment, the side collision detection sensor 60 can be attached to the surface of the resin panel 8 on the passenger compartment side, so that the waterproofness of the side collision detection sensor 60 can be improved.

Since the flange 20 is formed around the upper portion of the opening 19 and the opening 62 of the resin panel 8, water that may enter the sealed space 12 can be removed by the flange 20. Thereby, it is possible to reliably prevent water from entering from the pressure introducing portion 62 and to prevent a failure of the side collision detection sensor 60.
Moreover, in the part in which the collar part 20 was formed, the plate | board thickness of the resin panel 8 increases only by the protrusion dimension L1 of the collar part 20. As shown in FIG. Therefore, the rigidity of the resin panel 8 in the peripheral portion of the flange portion 20 can be increased. Here, since the flange portion 20 is formed so as to cover the upper periphery of the pressure introducing portion 62, the rigidity of the resin panel 8 around the pressure introducing portion 62 can be increased by the flange portion 20. The attachment strength of the collision detection sensor 60 can be increased. Moreover, since the rigidity of the resin panel 8 in the vicinity of the opening 19 can be increased, the resin panel 8 is difficult to bend, so that the sealing property between the resin panel 8 and the side collision detection sensor 60 can be more reliably ensured.

  Since the claw portion 26 is formed on the resin panel 8, the side collision detection sensor 60 can be reliably fixed to the resin panel 8. Further, since the claw portion 26 is formed so as to protrude from the surface of the resin panel 8, it is not necessary to provide a protrusion or the like protruding from the side collision detection sensor 60 side on the side collision detection sensor 60 side. For example, in the case where a protrusion protruding from the side collision detection sensor 60 is provided, it is necessary to provide a hole through which the protrusion penetrates the resin panel 8. However, in such a configuration, water from the sealed space 12 passes through the hole. In order to prevent this, a new seal structure is required. Therefore, the structure which formed the nail | claw part 26 in the resin panel 8 side like this embodiment can prevent the penetration | invasion of water, the failure of the side collision detection sensor 60, and can improve waterproofness.

  Since the claw portion 26 is formed, the side collision detection sensor 60 can be fixed by engaging the claw portion 26 with the back surface of the side collision detection sensor 60. Therefore, it is possible to fix the side collision detection sensor 60 which is generalized with a simple structure. Further, since the claw portion 26 has flexibility, the claw portion 26 is engaged with the surface of the side collision detection sensor 60 on the vehicle compartment side simply by pushing the side collision detection sensor 60 toward the claw portion 26. It is possible to perform installation work. Furthermore, since the claw portion 26 engages with the surface of the side collision detection sensor 60 on the passenger compartment side, it is necessary to form an engagement portion for engaging the claw portion 26 on the outer surface of the side collision detection sensor 60. Therefore, the outer shape of the side collision detection sensor 60 can be simplified.

  Since the two base ends of the claw portions 26 are located in the region between the flange portion 20 and the opening 62, these claw portions 26 are arranged in a portion having higher rigidity of the resin panel 8. can do. Therefore, the attachment structure of the side collision detection sensor 60 to the resin panel 8 can be further strengthened. Therefore, the attachment structure of the side collision detection sensor 60 can be strengthened, and problems such as excessive vibration or falling of the side collision detection sensor 60 due to vibration during traveling of the vehicle can be prevented.

  Since the bolt 28 is screwed into the boss hole 24 through the screw fixing hole 66 of the projection 63, the side collision detection sensor 60 can be fixed by the bolt 28 in addition to fixing by the claw portion 26. The attachment structure of the side collision detection sensor 60 can be further strengthened. Here, since the fixing structure of the protrusion 63 is screwed by the bolt 28, the screw engagement between the resin boss hole 24 and the bolt 28 may be loosened by vibration or the like as the vehicle 1 travels. However, in this embodiment, since the claw part 26 fixes the side collision detection sensor 60 to the resin panel 8, the side collision detection sensor 60 can be prevented from falling.

  Boss hole protrusions 22 are formed at both ends of the flange 20, and the boss holes 24 are formed in the boss hole protrusions 22 from the surface on the vehicle compartment side. It can be formed longer than the thickness. Thereby, the bolt 28 can be firmly fixed by the boss hole 24, and the side collision detection sensor 60 can be more reliably fixed. Since the boss hole projection 22 is connected to the flange 20, the resin panel 8 around the flange 20 can be more reliably reinforced. Moreover, since the boss hole 24 is formed in the protrusion part 22 for boss holes, the rigidity of the resin panel 8 around the boss hole 24 can be increased. Therefore, the attachment structure by the protrusion 63 of the side collision detection sensor 60 can be further strengthened.

  The present invention is not limited to the above-described embodiment. For example, in the present invention, the side collision detection sensor is held by the fixing portion, so that the protrusion and screw fixing of the side collision detection sensor as in the above-described embodiment are performed. The service hole is not necessarily provided. In addition, the fixing portion may not be configured with a claw portion such as a configuration having an insertion portion that is inserted into the side collision detection sensor.

  In the above-described embodiment, the mounting position of the fixing portion is such that a part (upper two) of the plurality (four) of the base ends are located in a region between the flange portion and the opening portion. It was set, but it is not limited to this. For example, the base ends of all the fixing portions may be located inside a region surrounded by the collar portion. In short, the base ends of at least one fixing portion are located in the region between the collar portion and the opening portion. If you do. For example, if the rigidity of the resin panel is sufficiently ensured, all of the base ends of the fixing portions may be located outside the region between the flange portion and the opening portion.

The shape of the collar portion is not limited to a substantially semicircular shape, and can be arbitrarily set as long as it is a shape that can prevent water from above from entering the pressure introducing portion, such as a substantially rectangular shape or a substantially triangular shape. Further, the flange portion is not limited to the configuration in which the boss hole protrusions are connected to both ends thereof, and the boss hole protrusions may not be connected to the flange portion, for example.
The method of detecting a collision by the side collision detection sensor is not limited to a method of determining a collision when the pressure fluctuation exceeds a predetermined value. For example, a collision is detected when the detected absolute value of the pressure exceeds a predetermined value. A method of determining may be used.
