Detailed description of the invention is by quoting the instance interpretation of accompanying drawing embodiments of the invention and advantage and feature.
Detailed description of the invention
Refer now to Fig. 1, Reference numeral 10 denoted overall vehicle latche assembly.Vehicle latche assembly 10 is often designed to the vehicle (not shown) of the car door with band door handle.Vehicle latche assembly 10 can be arranged on driver-side door, passenger-side door and rear row's passenger doors place.In addition, vehicle latche assembly 10 can be arranged on other position of vehicle, such as, car door opening on B post, or can be combined with the back door of vehicle such as lifting door, boot or tailstock door.
Vehicle latche assembly 10 comprises and is positioned at frame plate 14 housing 12 below, and frame plate 14 can help protection vehicle latche assembly 10 from damage and dirt and chip.Housing 12 such as utilizes multiple machanical fastener or welding to be installed in car door place.Rotatable pallet (not shown) keeps lance releasedly, to be maintained in its closed position by car door (or lifting door, boot, tailstock door etc.).This pallet is maintained in fastening position by ratchet 16, and this ratchet is operationally attached to eccentric part 18.Eccentric part 18 is as crank axle running, and it is operationally attached to interior bar 20, and this interior bar allows user's rotating eccentricity part 18, thus handles ratchet 16 to depart from pallet.This operation makes lance discharge from pallet and facilitate car door opening.
Eccentric part 18 extends to the second end 25 from first end 22 vertically.First end 22 is operationally attached to interior bar 20 and next-door neighbour's backboard 24, and backboard 24 forms the structural border of vehicle latche assembly 10 in conjunction with frame plate 14.Second end 25 is close to frame plate 14 and arranges.As mentioned above, eccentric part 18 is rotatable to operate together with ratchet 16 during car door switching motion.Eccentric part 18 is kept by least one capacity eccentric bearing 26.
In order to reduce or eliminate eccentric part 18 and the end-play at least between another above-mentioned parts, at least one securing member at least local is arranged around the part of eccentric part 18.The metal covering that particularly at least one securing member described is disposed in each parts is easy in the region contacted with each other.This securing member is optional from many securing members, such as packing ring 11 (Fig. 4) or one or more lining, will hereafter encyclopaedize this.
In a first embodiment, the first lining 28 is fixedly attached to eccentric part 18 and is arranged between the external surface 30 of eccentric part 18 and frame plate 14.Being fixedly connected with between the first lining 28 and eccentric part 18 realizes by many means for attachment expected.In one embodiment, the first lining 28 is riveted to eccentric part 18.First lining 28 substantially reduces the potential vertical motion of eccentric part 18, because the first lining 28 is fixed between eccentric part 18 and frame plate 14.
Comprise the second lining 32 in another embodiment.Second lining 32 is fixedly attached to backboard 24 and is arranged between the external surface 30 of eccentric part 18 and backboard 24.Can be realized by many modes as being fixedly connected with between the first lining 28, second lining 32 and backboard 24, such as, rivet.Second lining 32 makes eccentric part 18 and backboard 24 separate, the noise produced with the Contact of backboard 24 with the external surface 30 reduced or eliminate eccentric part.
First lining 28 and the second lining 32 all provide the interface between the face of parts separately, as mentioned above, to form damping to the energy transmitted through the first lining 28 and the second lining 32.Many known bush structures can be adopted.In one embodiment, the first lining 28 and/or the second lining 32 are the annular canister be made up of the flexible material be arranged in metal shell or outer tube.First and second linings 28,32 can be formed by many energy damping materials expected.Exemplary materials comprises such as rubber, synthetic rubber or polyurethane.Above-mentioned list is illustrative, instead of limit.As mentioned above, object surface is separated by the first and second linings 28,32, and allows certain amount of movement simultaneously.This mobile allowable offset part 18 moves freely, and reduces simultaneously or eliminate the propagation of the noise and vibration be associated with the Contact of each parts of vehicle latche assembly 10.
Referring now to Fig. 2 and Fig. 3, show the vehicle latche assembly 10 according to the second embodiment.Second embodiment of vehicle latche assembly 10 is similar on 26S Proteasome Structure and Function to the first embodiment in many aspects, thus adopts similar Reference numeral, there is omitted herein the description to the corresponding of component and repetition.
Eccentric part 18 comprises and in axial direction runs through from first end 22 to the second end 25 perforate 40 wherein extended.The through hole of this perforate 40 normally constant diameter, but perforate 40 can be formed as slit or other shape.Pin 42 to be arranged in perforate 40 and to comprise head 44 and main part 46.Main part 46 is arranged in perforate 40, and the diameter of head 44 is greater than the diameter of perforate 40, to guarantee on the position that head 44 is positioned at outside perforate 40.Head 44 can be such as tack, maybe can comprise bulbous construction.No matter what kind of precise geometry head 44 has, pin 42 all (at interior rod end 22 place) is riveted to eccentric part 18.The first lining 28 as detailed above can be comprised.Except above-mentioned benefit, the first lining 28 is also for head 44 provides ledge surface to form the riveted joint with eccentric part 18.The overall axial arrangement of vehicle latche assembly 10 that such embodiment is compact, because this reducing the possibility of the parts Contact undesirably had.
As shown in Figure 4 also with reference to figure 1-3, additionally provide the method 100 manufacturing vehicle latche assembly.Vehicle latche assembly 10 described above, and concrete structure member need not be further described again.Method 100 comprises the perforate 40 of 102 formation through eccentric part 18, and 104 make housing 12, frame plate 14, backboard 24 and eccentric part 18 operationally directly or indirectly be coupled to each other.106 main part 46 perforates 40 through eccentric part 18 of arranging pins 42, rivet 108 to eccentric part 18 to reduce frame plate 14, backboard 24 and eccentric part 18 moving axially relative to each other by pin 42.
Above-mentioned several embodiment maintains the operability of car door, associated noise is reduced to minimum simultaneously.This noise reduction is attractive to customer and allows car door continuous print the best to open and close operation.
Although the present invention has only been described in detail for the embodiment of limited quantity, easy understand the present invention embodiment disclosed in these should be not limited to.On the contrary, the present invention can revise to combine do not describe before this any amount of modification, amendment, replacement or equality unit, as long as their spirit and scope according to the invention.In addition, although described various embodiment of the present invention, can understand, many aspects of the present invention only can comprise the part in described embodiment.Therefore, the present invention should not be regarded as being confined to foregoing description, but is only limited by the scope of appended claims.
