Detailed description of the invention
Embodiment of the present disclosure is set forth at this.It should be understood, however, that disclosed embodiment is only example, and other embodiments can adopt multiple and alternative form.Accompanying drawing is not necessarily drawn in proportion; Can exaggerate or minimize some features to illustrate the details of particular elements.Therefore, concrete structure disclosed herein and functional details should not be construed as restriction, and as just for instructing those skilled in the art how to put into practice representative basis of the present invention in many aspects.As one of ordinary skill in the art will appreciate, to describe with reference to any one accompanying drawing in accompanying drawing and the different characteristic illustrated can with the integrate features shown in one or more other accompanying drawings, to produce the embodiment clearly not illustrating or describe.The combination of the feature illustrated is provided for the representative embodiment of typical apply.Various combination is consistent with the feature of amendment and the instruction of the disclosure, but, also can expect special application or enforcement.
Power actuated vehicle comprises multiple safety facilities (safety features), to help to protect automotive occupant, vehicle itself and object around.Structural safety facilities can be combined to remind and/or alerting driver under specific environment (such as, when vehicle is close to object) with sensing system.An example of sensing system is vehicle auxiliary system for parking, and vehicle auxiliary system for parking can comprise for detected object and the sensor that can give the alarm in response to object detection.Therefore, if (such as) vehicle back to during parking stall near an object, so auxiliary system for parking can alerting driver.
Another example of sensing system is pedestrian protection system, to provide protection for pedestrian and/or to reduce the injury owing to causing pedestrian with vehicle collision and causing.Such sensing system can detect object when colliding and activate vehicle response.Some sensor (such as, crash sensor) also can be determined to the type of the object of vehicle collision and corresponding signal is sent to safety system to activate vehicle response.Install the orientation of these sensors, position and method usually with the vehicle structure feature that adjoins coincide, to provide the performance of expectation.
Such as, crash sensor can be arranged in the region between the backplate of vehicle and the center beam of bumper of vehicle.The bumper/spoiler cover portion of vehicle backplate is an example in the type region.Vehicle backplate generally includes A-surface and B-surface.A-surface and/or outside face are that backplate is towards " outside " and/or the part (surface that pedestrian and other chaufeurs are seen usually) towards " away from vehicle ".B-surface and/or inside face are the part (surface that pedestrian or other chaufeur usually can not see) of backplate towards " inside ".The B-surface of safety lever cover is usually towards center beam of bumper and/or energy absorber.At present for sensor module is fixed and/or is arranged in backplate B-on the surface or the vehicle application of backplate B-near surface use and there is weld bolt be attached to thermoplastic member on it.Thermoplastic member is usually by thermal welding or be welded to B-surface.Then nut is used to be attached on weld bolt by sensor mechanism.But bolt extends less desirable contact hard spot (description as below) towards center beam of bumper.
Referring now to Fig. 1, as known in the art, crash sensor assembly 2 is attached to vehicle bumper cover 4.Sensor module 2 is installed to the B-surface 8 of bumper/spoiler cover 4.Sensor module 2 comprises the plasticity support 10 with bolt 12 and nut 11, so that crash sensor 14 is installed to B-surface 8.Size 18 is the distances being positioned at region 21 between the end 20 of bolt 12 and center beam of bumper 6.End 20 is examples of contact hard spot.Vehicle Safety Standard can provide guidance for the suitable minor increment (referred to here as press-in distance (crushdistance)) between contact hard spot and center beam of bumper or between sensor module and center beam of bumper.Vehicle manufacturer also can have the internal standard about press-in distance.
Such as, sensor module 2 place on bumper/spoiler cover 4 or neighbouring collision can guide bolt 12 and nut 11 to move towards center beam of bumper 6.If the outermost end conflict center beam of bumper 6 of end 20, so sensor 14 can owing to damaging and/or destroying and shut-down operation.At the aspect of performance of sensor, in press-in apart from too small, collision may cause sensor 14 just can not operate before completing its task.On the contrary, larger press-in distance can after an impact for sensor 14 provides the more time to operate.Therefore, can expect to make the element of sensor module in region 21 minimize and/or eliminate, maximize to make press-in distance.Such as, because nut 11 and bolt 12 need mechanically sensor 14 to be fastened to bumper/spoiler cover 4, so the lateral dimension of plasticity support 10 can contribute to forming shorter press-in distance.Other safety requirements (such as, preferably screwing number between bolt 12 and nut 11) also can contribute to forming shorter press-in distance.Elimination plasticity support 10, nut 11 and bolt 12 can produce larger press-in distance and reduce one and contact hard spot in region 21.
Referring now to Fig. 2, as known in the art, sensor module 50 is attached to vehicle backplate 51.Similar with sensor module 2, sensor module 50 is mechanically attached to support 52 by bolt 54, nut 55 and lining 56.Support 52 be attached to backplate B-surface 57 and bolt 54 extend towards center beam of bumper (not shown).The same with sensor module 2, the combination (such as, support 52, bolt 54 and nut 55) of support, screw bolt and nut can cause shorter and more undesirable press-in distance.
Except press-in distance except, when crash sensor be positioned at vehicle (such as, the front bumper cover of vehicle or rear bumper cover (depending on the travel direction of vehicle)) place, edge or neighbouring time, can improve and/or improve collide time detecting pedestrian ability.Usually, the edge of vehicle comprises backplate, and this backplate is by can be that material that is thin and that comprise aesthetic design factor is made.The use of the fastener that aesthetic design factor may limit and/or hinder the use of the traditional fastener needing to run through font lower shroud or the part corresponding with attachment position on A-surface can be made to be out of shape.Above-mentioned design constraint, performance requriements and aesthetic factors propose lot of challenges for B-surface sensor (such as, pedestrian protecting sensor) being installed to desired vehicle bumper cover and/or backplate.
Fig. 3 show be arranged on power actuated vehicle bumper/spoiler cover or backplate on exemplary sensor assembly 60.Sensor module 60 can comprise sensor 62, sensor housing 64 and plane lug (planar tab) 66.The example of sensor 62 includes but not limited to acceleration pick-up and/or pressure sensor.Lug 66 can be embedded in sensor module 62 and can be bonded to the backplate B-surface 68 of backplate bumper/spoiler cover 70.Two examples of adhesive method can comprise ultrasonic welding and adhesive agent bonding.The thickness of lug 66 can preferably between one millimeter to three millimeters, so that carry out the ultrasonic welding expected.Use the ultrasonic welding with the lug 66 of more than three millimeters thickness may cause the A-of bumper/spoiler cover 70 surface 72 depression or other distortion occur.Use its undercapacity of ultrasonic welding possibility with the lug 66 of less than one millimeter thickness so that sensor module 60 is fixed to B-surface 68.Lug 66 can be (being not limited thereto) plasticity zone or the material identical with the material for corresponding bumper/spoiler cover.Distance between B-surface 68 and sensor module 60 can be less than or equal to the thickness of the lug 66 of expectation.In addition and/or optionally, lug 66 can be the extendible portion of sensor housing 64.
Therefore, as compared to the sensor module in Fig. 1 with Fig. 2, sensor module 60 can not use machanical fastener (such as, bolt) when is arranged on B-surface 68 substantially, thus the front and back that sensor module 60 is taken are space-minimized and produce larger press-in distance (as shown by the dimension 75).This structure for sensor module 60 also can make the quantity of the vehicle assembly in region 78 and/or element minimize.Although the preferred length of size 75 can be more than or equal to 70 millimeters, the length of size 75 can according to the variation in thickness of the thickness of sensor module 60 and lug 66.Each extra measuring unit increasing press-in distance (being size 75 in this example) all can provide extra pedestrains safety benefit.More space between the exemplary collision point at center beam of bumper 76 and bumper/spoiler cover 70 place can (such as but not limited to): (i) after an impact for Vehicle security system provides the more time, to receive, to process and in response to the detection signal carrying out sensor 60; (ii) provide larger cavity and/or space (such as, region 78), using as contributing to after an impact reducing crusherbull zone district to the injury of pedestrian.
In circuit (line) and/or sub-assembly environment, sensor module 60 also can provide the advantage about operation assembling.The example of current support installing method can comprise occlusion, bond and be welded to vehicle backplate.Some sensors (such as, parking aiding sensors) may need a hole or multiple hole in backplate, with attached sensors support before backplate is painted or after japanning.Other sensors (such as, those sensors in pedestrian's sensing system) may not need the hole through backplate, but may comprise for other steps multiple of assembling and adhere to.Sensor module is installed to the quantity of the control step that vehicle bumper cover comprises by minimizing and reduces costs by sensor module 60.
The sensor module 60 be bonded on B-surface 68 also can affect the performance of pedestrian protection system.Such as, sensor 62 expect function identifiable design and/or determine collide time object type.The feature (such as but not limited to density and weight) of object can change the effect that can affect collision be (such as between dissimilar object, with vehicle compared with the collision of pedestrian, vehicle can have different collision effects from the collision of tree for vehicle).There is the type of object when can identify and/or determine to collide and the security feature activating the sensing system of response based on such confirmation result can contribute to the injury that reduces vehicle and/or object.The security feature of sensing system can be determined when colliding: the density of object whether lower than predetermined threshold, thus activates vehicle response, to reduce the power of vehicle collision object.
Such as, if the collision of vehicle to pedestrian occurs in bumper/spoiler cover 70 place of vehicle, and security of system feature receives the detection signal of sensor 62, wherein, the density of this detection signal instruction pedestrian is below or above predetermined threshold, and so security feature can indicate the car bonnet of opening vehicle or energy absorbing engine cover panel can be indicated to launch to reduce the size of the power being delivered to pedestrian from vehicle.This effect is similar to crusherbull zone district and can comes together with larger press-in distance to improve effect.Therefore, sensor 62 and/or sensor module 60 are arranged on impact zone place potential on vehicle or near be favourable, with collide time promote detect.
Fig. 4 A to Fig. 7 shows the exemplary sensor assembly 100 be positioned on bumper/spoiler cover 102 for power actuated vehicle.Sensor module 100 can comprise sensor 103 and have the support 104 of housing 105 and pedestal 106.The example of sensor 103 can comprise acceleration pick-up as above or parking aiding sensors.In some applications, pressure sensor can be another example of sensor 103.Plane lug (not shown) can be embedded in pedestal 106 and can be bonded to the backplate B-surface 108 of bumper/spoiler cover 102.Two examples of adhesive method can comprise ultrasonic welding and adhesives.Plane lug preferably can have the thickness between one millimeter to three millimeters, so that carry out the ultrasonic welding expected.The ultrasonic welding with the plane lug of more than three millimeters thickness may cause the A-of bumper/spoiler cover 102 surface 107 depression or other distortion occur.There is its undercapacity of ultrasonic welding possibility of the plane lug of less than one millimeter thickness so that sensor module 100 is fixed to B-surface 108.Plane lug can be but be not limited to plasticity zone or the material identical with the material for bumper/spoiler cover 102.Distance between B-surface 108 and sensor module 100 can be less than or equal to the thickness of the plane lug of expectation.In addition and/or optionally, plane lug can be the extendible portion of pedestal 106.
Fig. 4 A to Fig. 4 C shows the support 104 being in primary importance 118.Sensor 103 before showing installation.Sensor 103 can comprise two extensions, 110, two locking lugs 112 and sensor connector 114.Support 104 can comprise one or more groove 119, to hold corresponding locking lug 112.Sensor housing 105 can comprise two sheets (segment) 115, and each all has hole 116, to hold extension 110 and to be conducive to sensor 103 to be attached to housing 105.Lockable mechanism can comprise pin 113, and pin 113 has spring, with towards pedestal 106 bias voltage housing 105.As described further below, when sensor 103 is installed to housing 105, described bias voltage can provide the controlled of housing 105 and/or optionally rotate.Housing also can comprise plural 115.
Such as, referring now to Fig. 4 E, three sheets 115 can reduce the quantity that sensor 103 is installed to the selection that housing 105 can obtain by user.Three sheets 115 only can provide a kind of selection sensor 103 being installed to housing 105, and the chance that therefore user makes a mistake in installation/assembly manipulation is less.Further, three sheets 115 are used to prevent off-square from installing completely.Extra sheet 115 also can increase the structure integrity of sensor module 100.
Referring now to Fig. 5 A, two sheets 115 and hole 116 can be constructed to when sensor connector 114 towards wall 117 sensor 103 is attached to housing 105.Wall 117 can have curved profile and can arrange near sensor connector 114, carries out interactive access (mating access) to prevent another adaptor union (such as, wire harness connector) to sensor connector 14.If comparatively paid close attention to, sensor 103 is correctly installed to housing 105, so expects to prevent interactive access.Such as, the surrounding environment of sensor module 100 may be like this: the off-square of sensor 103 is installed and interfered with the assigned address for another assembly.Or off-square installs the operation may disturbed in the assembling preset subsequently.The sensor 103 illustrated in fig. 5 is installed to housing 105 and is positioned at primary importance 118.Although shown primary importance 118 is positioned at vertical orientation, also multiple orientation can be obtained.
