Like this, above-mentioned connecting portion 22a, its coupled condition is weaker than the coupled condition of other connecting portion 22, thereby by elastic body 84, can allow the displacement of door assembly 8, can not suppress door assembly 8 thus and produce low-frequency vibration, the especially vibration of 1 * 1 pattern with respect to inner plate of car door 6.In addition, the whole connecting portions 22 being set up in parallel on the direction of its opposition side from car door door bolt side all can be provided with elastic body 84.

Then, by Fig. 2 and Fig. 9 the structure of car door door bolt portion 16 and the connection structure of door assembly 8, inner plate of car door 6 and car door door bolt portion 16 are described.Fig. 9 is that expression is fastened the cutaway view of the connection structure of bilge construction and door assembly, inner plate of car door and car door latch bracket with a bolt or latch along the car door of IX among Fig. 2-IX line observation.

The automobile door structure of present embodiment, when closed door, the transfer of vibration that car door bolt mechanism 20 is produced is given door assembly 8, utilizes low frequency sound aggrandizement apparatus, and the specific low-frequency vibration in the above-mentioned vibration is increased.Therefore, present embodiment is that when closed door, the vibration that car door bolt mechanism 20 is produced more effectively passes to car door door bolt portion 16 structures of door assembly 8, and the connection structure of door assembly 8, inner plate of car door 6 and car door door bolt portion 16.

At first, as shown in Figure 9, car door latch bracket 18, a plurality of positions shown in the d in Fig. 9 are fixed by welding among the aft end face 6g and rear area 6c of inner plate of car door 6.Here, in position shown in Figure 2, car door bolt mechanism 20 is fixed on this car door latch bracket 18.Car door latch bracket 18, it is positioned at the position of the above and below of above-mentioned car door bolt mechanism 20, and the position of car door bolt mechanism 20 promptly is not set, and is the curved shape that can constitute triangle closed section (shown in the e among Fig. 9) with inner plate of car door 6.

As Fig. 2 and shown in Figure 9, car door latch bracket 18 extends to the position that overlaps with door assembly 8 to the place ahead of car body fore-and-aft direction.6 connecting portion 22b in this car door door bolt portion 16, door assembly 8, inner plate of car door 6 and car door latch bracket 18, can tighten together by bolt 80 and nut 82, make the connection rigidity (door assembly 8 is with respect to the installation rigidity of inner plate of car door 6) of connecting part 22b be higher than the connection rigidity of other connecting portions 22 beyond the connecting portion 22b.As shown in Figure 2, above-mentioned connecting portion 22b, along from car door door bolt portion 16 towards the direction of door assembly 8, promptly with the crossing direction of transfer of vibration direction (being the car body fore-and-aft direction the present embodiment) (along the end edge portion of the car door door bolt side of door assembly 8), extend by 2 row and to be provided with.

And, be provided with connecting portion 22b the zone, be door assembly 8, inner plate of car door 6, and the coincidence zone of car door latch bracket 18, be formed with the reinforcement fin (rib) 86 that extends straight towards the direction of door assembly 8 along from car door door bolt portion 16 with door assembly 8.

Then, by Fig. 2 and Fig. 8 explanation, for the vibration that makes bass is more positively discharged and is arranged on vibration blocking-up additional strengthening on the inner plate of car door 6 from door assembly 8.

In the present embodiment, be arranged on the inner plate of car door 6 with additional strengthening by vibrating blocking-up, the vibration that car door bolt mechanism 20 is produced can more effectively pass to door assembly 8 on the one hand, on the other hand, can make vibration that car door bolt mechanism 20 produced and the vibration that passes to door assembly 8, be difficult to pass to inner plate of car door 6.

Specifically, at first, as shown in Figure 2, on inner plate of car door 6, be formed with the vibration blocking-up rib 90 that is continuous wire extension.As shown in Figure 8, this vibration blocking-up rib 90, the f in Fig. 8, g2 place are bent, and constitute the end difference 92 that rigidity is improved thus.

Then, as shown in Figure 2, this end difference 92, be included in face except a side that is provided with car door door bolt portion 16, front region 6b, upper area 6d beyond the promptly regional in the wings 6c, and lower zone 6e in, be the 2nd vibration blocking-up portion 92b of continuous extension to form among the 1st vibration blocking-up 92a of portion that surrounds door assembly 8 and the regional in the wings 6c.The 2nd vibration blocking-up 92b of portion, above and below in car door door bolt portion 16, extend continuously from the 1st vibration blocking-up 92a of portion respectively, and extend to boundary line with the aft end face 6g of inner plate of car door 6, thereby the upper area 6d of inner plate of car door 6 and lower zone 6e are cut apart in car door door bolt portion 16.In addition, the aft end face 6g of inner plate of car door 6 also can form the end difference that extends continuously from the 2nd vibration blocking-up 92b of portion.

Then, as shown in Figure 8, this end difference 92 has the height more outstanding with respect to door assembly 8.By said structure, vibration is more effectively blocked, the sound of car that door assembly 8 discharges can not escaped to the four sides simultaneously, thereby can further improve sound emittance.In addition, as shown in figure 10, also can constitute this vibration blocking-up rib 90 by reinforced rib portion 94.This reinforced rib portion 94 also can be identical with above-mentioned end difference 92, and its rigidity can be increased to can block vibration, can have the height more outstanding with respect to door assembly 8 in addition.

The main action effect of embodiment of the present invention then is described.

The automobile door structure of present embodiment, by low frequency sound aggrandizement apparatus, make in the vibration that passes to car door bolt mechanism 20 door assembly 8, that when closed door, produced, can make the occupant obtain the vibrational energy of the specific low frequency of thick and heavy sensation, be transformed to the sound emittance through increasing, therefore the bass that door assembly 8 is discharged is increased.

By this bass, can make the occupant in the car feel that the sound of closed door is very thick and heavy through discharging to the passenger compartment side in the bass that increases.And, being discharged into the bass of passenger compartment side, its HFS can be decayed at door trim plate 10 places, thereby can make the passenger more positively obtain thick and heavy sensation.

Through being released to the bass in the car outside in the bass that increases, be released to the space between door skin 2 (outdoor) and inner plate of car door 6 and the door assembly 8 (chamber interior), and pass door skin 2 and be released to outside the car.Therefore, the outer occupant of car can feel that the sound of closed door is very thick and heavy.And, passing the sound of the closed door of door skin 2, its radio-frequency component is attenuated, thereby is in the outer occupant of car and can more positively obtains thick and heavy sensation.

Then specify the action effect of present embodiment.

At first, present embodiment, by formed the 1st to the 4th additional strengthening (rib) on the door assembly 8 rigidity of door assembly 8 is adjusted, thereby can be by 200Hz or following low frequency, the vibration that makes door assembly 8 produce 1 * 1 pattern increases the bass that discharges from door assembly 8 with this.

At first, the 1st additional strengthening, for the approximate centre position with door assembly 8 is the center, ring-type rib in the form of a ring, promptly the ring-type heavy section 50, by this ring-type heavy section 50, the middle section of door assembly 8 strengthened in the form of a ring.Therefore, be easy to generate the vibration of 1 * 1 pattern.Specifically, can utilize this ring-type heavy section 50, can be at the vibrative belly in the approximate centre position of door assembly 8.In addition, this ring-type heavy section 50, can the concentric circles state be provided with a plurality of, thereby the vibration that can more positively produce 1 * 1 pattern.In addition, high-frequency vibration also is difficult to produce.

Then, the 2nd additional strengthening, it is the linearity fin 56 that extends to opposite body hinge 14 1 sides from car door door bolt portion 16 1 sides of door assembly 8 through the approximate centre position of door assembly 8, utilize this linearity fin 56, the rigidity of a tunable integer door assembly 8 on the car body fore-and-aft direction reaches even.Therefore, can prevent in the door assembly 8, the vibrative node in roughly whole zone except circumference, thus the vibration of 1 * 1 pattern is easy to generate.In addition, this vibration can make roughly whole door assembly 8 have the vibration belly of level and smooth vibration distribution (distribution of amplitudes).Thus, by level and smooth vibration distribution, can more positively improve the sound radiation efficiency of bass.

Especially, linearity fin 56, the transmission of vibration direction that is produced along car door bolt mechanism 20, promptly extend to the direction of opposite body hinge 14 1 sides through the approximate centre position of door assembly 8 from car door door bolt portion 16 1 sides, thereby the vibration that can produce 1 * 1 pattern effectively.

In addition, linearity fin 56, integrally formed with ring-type heavy section 50 (the 1st additional strengthening), thereby be formed with the zone of a plurality of ring-type heavy sections 50, can be used as the belly of one vibration, and vibrate easily, in addition, can prevent that the boundary portion that is positioned at outermost ring-type heavy section 50d and its Outboard Sections from bending taking place and vibrative node.Therefore, the vibration of 1 * 1 pattern is more positively produced.And high-frequency vibration also is difficult to produce.

Then, the 3rd additional strengthening, be in the outer regions scope of door assembly 8, on the direction at the approximate centre position of door assembly 8, a plurality of radial fin 60 with radial extension, by above-mentioned radial fin 60, can adjust the distribution of the belly of vibration, the amplitude from the outer regions of door assembly 8 to the approximate centre position is increased gradually.Here,, be easy to generate the node of vibration, and outer regions becomes the marginal portion of distribution of the belly of vibration with the circumference of inner plate of car door 6 bonded assembly door assemblies 8.Therefore, by in the outer regions of above-mentioned door assembly 8, formation is towards the approximate centre position of door assembly 8 fin 60 radially, can prevent from bending to take place and vibrative node in above-mentioned outer regions, thereby the vibration of 1 * 1 pattern can roughly produced with level and smooth vibration distribution in the whole door assembly.So, can more positively improve the sound radiation efficiency of bass.And high-frequency vibration also is difficult to produce.

And a plurality of radial fins 60 with the interval of adjacent separately radial fin 60, for irregular, thereby can prevent to be set up in parallel and the generation of the specific high-frequency vibration that forms with fixed interval.Especially can prevent hundreds of Hz (for example 300Hz) in the generation of vibration of time pattern.

And the width of a plurality of radial fins 60 and/or height are adjusted into respectively, make the stiffness distribution of outer regions of door assembly 8 roughly even.In addition, its width and/or height can be adjusted to, and make the quality of unit area of outer regions of door assembly 8 roughly even.Thereby, can make the vibration distribution of 1 * 1 pattern that door assembly 8 produced comparatively level and smooth.Thereby can improve the sound radiation efficiency of bass.And, even form fitfull between a plurality of radial fin 60 at interval, the vibration of 1 * 1 pattern is positively produced.

And, in the outer regions, be provided with a side and the formed radial fin 60 of opposition side (being provided with a side of body hinge 14) thereof of car door door bolt portion 16, be longer than the formed radial fin 60 of other sides in the outer regions.Thereby, in the door assembly 8, be provided with a side and the opposition side (being provided with a side of body hinge 14) thereof of car door door bolt portion 16, can prevent the generation of torsion oscillations.Therefore, can from car door door bolt portion 16 1 sides on the direction of opposite body hinge 14 1 sides, the vibration that produced of transfer car door bolt mechanism 20 effectively, thereby the vibration that produces 1 * 1 pattern effectively.And, because door assembly 8 is longer on the car body fore-and-aft direction, thereby can have long length by making the fin 60 that on the car body fore-and-aft direction, is provided with radially, make roughly whole door assembly 8 more positively produce the vibration of 1 * 1 pattern.

Especially, as mentioned above, be provided with the coupled condition of the door assembly 8 of side of car door door bolt portion 16 and opposition side (being provided with a side of body hinge 14) thereof with respect to inner plate of car door 6, coupled condition than other parts is more firm, what make near the connecting portion 22 radial fin 60 simultaneously has long length improving rigidity, thereby can make the rigidity of whole door assembly 8 reach balance.So, can produce the vibration of 1 * 1 level and smooth pattern of vibration distribution from the side that is provided with car door door bolt portion 16 of door assembly 8 to its opposition side.

On the other hand, in the upper end side of door assembly and lower end side along connecting portion 22a place that the car body fore-and-aft direction is set up in parallel, adopt the more weak connection that allows displacement, it is shorter to be positioned near the radial fin 60 of these connecting portions 22a simultaneously, so near the rigidity of the part the above-mentioned connecting portion 22a can not improve a lot, thereby can not suppress the vibration of 1 * 1 pattern that door assembly 8 produced.

Then, the 4th additional strengthening 70, be to the opening that the formed hole of door assembly 8 portion 44,46,48, recess 40 are strengthened strengthen fin 72, hole portion strengthens fin 74 and recess is strengthened fin 76, by above-mentioned each fin, can make from hole portion, recess to the part around it and obtain uniform rigidity.So, can prevent hole portion 44,46,48, recess 40 vibrative nodes, or prevent to bend in the boundary portion of above-mentioned hole portion, recess and its peripheral part.That is, hole portion 44,46,48, recess 40 and peripheral part thereof form (homophase) vibration of one easily, thereby door assembly is easy to generate the vibration of 1 * 1 pattern, and the vibration distribution of belly that should vibration is very level and smooth.Therefore, the sound radiation efficiency of the vibration of particular low frequency is increased.And, also can prevent the generation of high-frequency vibration.

And, the height that hole portion strengthens fin 74 and recess reinforcement fin 76 is, the part more little with the intersection point distance apart of hole portion or recess (44,40) and vibration neutral surface c is high highly more, the height that opening is strengthened fin 72 is that the big more part of aperture area is high highly more, thereby the poor rigidity of hole portion 44,46,48, recess 40 and its peripheral part is less, thereby make stiffness distribution even.

Then, the automobile door structure of present embodiment can constitute low frequency sound aggrandizement apparatus with respect to loud speaker with the mounting structure of hole portion 46 by loud speaker, makes roughly whole door assembly 8 positively produce the vibration of 1 * 1 mode of vibration.

Specifically, loud speaker is with hole portion 46, and with respect on the orthogonal thereto direction of the direction at the approximate centre position of door assembly 8, position roughly arranged side by side is provided with the installation portion 46c of loud speaker 34.When if door assembly 8 produces the vibration of 1 * 1 pattern, distribution of amplitudes increases gradually for the amplitude from the outer regions of door assembly 8 to the substantial middle zone.In contrast, rigidity is upward existed with certain length at radial direction (direction from outer regions to middle section) by the part of bigger raising, and then this part just can suppress the vibration generation of 1 * 1 pattern.

Present embodiment, with respect to the position that on the orthogonal thereto direction (circumferencial direction) of the direction at door assembly 8 approximate centre positions, roughly is set up in parallel loud speaker is being installed, thereby can improve the rigidity of door assembly 8 in a circumferential direction, on radial direction, then avoid improving the rigidity of door assembly 8.So door assembly is easy to generate the vibration of 1 * 1 pattern, and can make the vibration distribution (distribution of amplitudes) of the belly of this vibration very level and smooth.And, loud speaker is reduced with the poor rigidity of its peripheral part with hole portion 46, thereby make stiffness distribution even.Therefore, can as mentioned above sound radiation efficiency be increased.

Then, the automobile door structure of present embodiment can be by the low frequency sound aggrandizement apparatus that mounting structure constituted of window regulator 24 with respect to door assembly 8, makes roughly whole door assembly 8 positively produce the vibration of 1 * 1 mode of vibration.

At first, the part of rail portion 28 and carriage 30a surround this operation around with hole portion 44 with hole portion 44 in operation, and the leading section of the upper end of rail portion 28 and carriage 30a is installed on the door assembly 8 near with hole portion 44 in operation respectively.So, can make the uneven part of rigidity in the door assembly 8 according to installation site and the rail portion 28 of window regulator 24 and the shape of carriage 30a of window regulator 24, i.e. operation is even with the stiffness distribution of its peripheral part with hole portion 44.Therefore, can increase sound radiation efficiency as mentioned above.

And the carriage 30b of window regulator 24 extends to the approximate centre position of door assembly 8, and its leading section is installed in the approximate centre position of door assembly 8.So the weight of window regulator 24 can be born by the approximate centre position of door assembly 8 largely, therefore, can more positively produce with above-mentioned central part is the vibration of 1 * 1 pattern of the belly of vibration.In addition, the amplitude of above-mentioned vibration is increased.

And carriage 30b can be installed on the ring-type heavy section 50a.This ring-type heavy section 50a is exactly the part that rigidity is improved originally, even thereby by carriage 30b window regulator 24 is installed, also can not suppress the generation of vibration of 1 * 1 pattern.In addition, when carriage 30b is installed on the linearity fin 56, also can produce same action effect.In addition, when being installed in other car door functional components on the door assembly,, also can produce same action effect as long as be installed on the ribs such as heavy section 50, fin, reinforced rib.

And window regulator 24 can be installed in the approximate centre position of door assembly 8 by carriage 30b, can be installed near the position of door assembly 8 with respect to the installation portion of inner plate of car door 6 by carriage 30a.This door assembly 8 is with respect near the position of the installation portion of inner plate of car door 6, is the less part of amplitude in the vibration that produced of door assembly 8, thereby can not suppress the vibration of 1 * 1 pattern that door assembly 8 produced.Therefore, can be at the approximate centre position of door assembly 8, with than the vibrative belly of large amplitude, and can not suppress this vibration, thereby be produced with level and smooth vibration distribution (distribution of amplitudes) in the vibration of whole door assembly 8,1 * 1 pattern.Therefore, can as mentioned above sound radiation efficiency be increased.

Then, door assembly 8 is to adopt resin material, thereby its formability is higher.So, as the 1st to the 4th additional strengthening 50,56,60,70 of low frequency sound aggrandizement apparatus; Loud speaker is with respect to the mounting structure of loud speaker with hole portion 46; And window regulator 24 can be easily positioned on this resin door assembly 8 with respect to the mounting structure of door assembly 8.Therefore, can low frequency sound aggrandizement apparatus be set with low cost.And, need not to increase weight or reduce weight, low frequency sound aggrandizement apparatus can be set.In addition, can not reduce when making and the transaction capabilities when installing yet.In addition, can be by only adjusting the simple structure of rigidity, increase the bass that makes the occupant obtain thick and heavy sensation.

Illustrate that then in the automobile door structure of present embodiment, door assembly 8 is with respect to the action effect of the mounting structure of inner plate of car door 6.

In the present embodiment, at the connecting portion 22a that is set up in parallel towards the direction of its opposition side from car door door bolt portion 16 1 sides, its coupled condition is weaker than other connecting portion 22, can allow door assembly 8 to produce displacements.So, can not suppress the vibration of 1 * 1 pattern of the door assembly 8 that increased by low frequency sound aggrandizement apparatus.

Especially above-mentioned connecting portion 22a, be arranged near the roughly middle position of car door door bolt portion 16 1 sides towards the direction of its opposition side, near this centre position is from car door door bolt portion 16 1 sides bigger position of amplitude towards the belly of the vibration of 1 * 1 pattern that the direction of opposite body hinge 14 1 sides distributes, thereby can not suppress the vibration of this 1 * 1 pattern.

And connecting portion 22a can pass through elastic body 84, utilizes bolt 80 and nut 82 that door assembly 8 is connected on the inner plate of car door 6, thereby the displacement that can allow door assembly 8 to produce with respect to inner plate of car door 6 effectively.

The action effect of the connection structure of the structure of car door door bolt portion 16 and door assembly 8, inner plate of car door 6 and car door door bolt portion 16 then is described in the automobile door structure of present embodiment.

In the present embodiment because door assembly 8, inner plate of car door 6, and car door latch bracket 18 secured together, thereby the vibration that car door bolt mechanism 20 is produced can pass to door assembly 8 effectively.Here, the vibration that passes to door assembly 8 is big more, and the low-frequency vibration that is increased by low frequency sound aggrandizement apparatus is also big more.So, can increase the bass that makes the occupant obtain thick and heavy sensation effectively.

Especially the installation rigidity of above-mentioned connecting portion 22b secured together is higher than other connecting portion 22, thereby can more effectively transmits above-mentioned vibration.In addition, the connection that tightens together can be undertaken by a plurality of bolts 80, above-mentioned bolt 80 can along from car door door bolt portion 16 towards the direction of door assembly 8, promptly along the direction that intersects with the transfer of vibration direction, be provided with by 2 row, thereby transmitting vibrations more effectively.

In addition, constitute the closed section of triangle between car door latch bracket 18 and the inner plate of car door 6, thereby the vibration that car door bolt mechanism 20 is produced can pass to door assembly 8 effectively.Here, as shown in Figure 9, when closed door, the car door door bolt (not shown) and the breech lock butt of car door bolt mechanism, inner plate of car door 6, being subjected to part shown in the h among Fig. 9 is fulcrum, direction shown in the i in Fig. 9 (with the direction of car body above-below direction as central axis) produces crooked bending force.That is, if do not constitute the closed section of triangle, inner plate of car door 6, by the effect of above-mentioned bending force, and can follow that end face 6g thereafter is approaching mutually with rear area 6c, the flexural deformation that separates and produce vibration.

On the other hand, because inner plate of car door 6 and car door latch bracket 18 constitute the closed section of triangle, thereby inner plate of car door 6 is difficult to distortion.So the vibrational energy that car door door bolt portion 16 is produced can not become the energy that makes inner plate of car door 6 distortion, its major part can be used as the vibrational energy that door assembly 8 is vibrated laterally, and passes to door assembly 8 effectively.So, can be as mentioned above, the vibration that on the car body fore-and-aft direction (from the direction of car door door bolt portion 16 1 sides) of door assembly 8, positively produces 1 * 1 pattern of belly with 1 bigger vibration towards its opposition side.

In addition, zone secured together in the door assembly 8, can be formed with along car door door bolt portion 16 towards the side of door assembly 8 upwardly extending reinforcement fin 86, thereby car door can be fastened with a bolt or latch the vibrational energy that portion 16 produced and pass to door assembly 8 effectively.

Then illustrate in the automobile door structure of present embodiment, in order more positively to discharge the bass vibration and to be arranged on the action effect of the vibration blocking-up of inner plate of car door 6 with rib 90 from door assembly 8.

In the present embodiment, other regional 6b, 6d, the 6e except the rear area 6c that is fixed with car door door bolt portion 16 1 sides of inner plate of car door 6, be formed with the vibration blocking-up rib 90 (the 1st vibration blocking-up 92a of portion) that surrounds door assembly 8, thereby the vibration that passes to door assembly 8 can further not pass to each regional 6b, 6d, 6e, therefore can prevent the sound radiation that inner plate of car door 6 produces high frequency audios.That is, inner plate of car door 6 adopts steel plate materials, and each regional 6b, 6d, 6e area are less relatively, and its profile, especially peristome 6a are very complicated, thereby be easy to produce high frequency audio, but the vibration that comes from door assembly 8 transmission is less, thereby can prevent the generation of above-mentioned high frequency audio.

And, the 2nd vibration blocking-up 92b of portion, extend continuously from the 1st vibration blocking-up 92a of portion respectively the above and below in car door door bolt portion 16, and the vibration that car door bolt mechanism 20 is produced is difficult to pass to the upper area 6d and the lower zone 6e of inner plate of car door 6.So, can prevent the upper area 6d and the lower zone 6e of inner plate of car door 6, and with above-mentioned zone 6d, 6e bonded assembly front region 6b, the sound radiation that produces high frequency audio.

In addition, the vibration blocking-up is continuous wire with rib 90 extends, thereby can more positively obtain the action effect of above-mentioned vibration blocking-up with rib 90.

On the other hand, rear area 6c forms the vibration blocking-up rib 90 that surrounds door assembly 8, thereby the vibration that car door bolt mechanism 20 is produced can be passed to door assembly 8 effectively.

And vibration blocking-up has the higher end difference of rigidity 92 with rib 90, thereby can block effectively from door assembly 8 and pass to the vibration of inner plate of car door 6 or be directly passed to the vibration of inner plate of car door 6 from car door bolt mechanism 20.And, can strengthen with 90 pairs of inner plate of car door 6 of rib by vibration blocking-up, thereby inner plate of car door 6 is difficult to produce and vibrates, thereby can suppress the generation of high frequency audio.

In addition, this end difference 92, more outstanding with respect to door assembly 8, thereby end difference 92, be periphery with respect to door assembly 8 relative wall on interior side direction.So,, can not escape, thereby can not reduce the sound emittance that discharges from door assembly 8 from the gap between door assembly 8 and the inner plate of car door 6 from the bass that door assembly 8 is discharged.Especially in the present embodiment, along the peripheral part of door assembly 8 from being provided with a plurality of connecting portions 22, and in connecting portion 22a permission generation displacement, thereby when door assembly 8 produces vibration, be easy to generate the gap between door assembly 8 and the inner plate of car door 6, thereby can more effectively realize above-mentioned effect.In addition, constitute same vibration blocking-up with rib 90, also can obtain same action effect at reinforced rib portion 94 places.

In addition, present embodiment only illustrated that automobile door structure of the present invention is applied to the situation of driver door, but automobile door structure of the present invention also can be applicable to tail gate, slip car door etc.
