Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Instrument desk glove box lock mechanism, comprising: lock tongue guide rod 1 and lock tongue connecting rod 2, lock tongue guide rod 1 are parallel with lock tongue connecting rod 2
Arrangement；Interlinked mechanism 3, one end are connected with lock tongue guide rod 1, and the other end is connected with lock tongue connecting rod 2；Unlock piece (is not shown in figure
Show), one end of unlock piece (not shown) is connected with lock tongue guide rod 1, and the other end is arranged in outside glove box, and unlock piece (figure
In do not show) lock tongue guide rod 1 can be driven mobile to 2 body of rod direction of lock tongue connecting rod；Resetting-mechanism 5 passes through two elastic elements
51 be connected respectively with lock tongue guide rod 1, lock tongue connecting rod 2；Wherein interlinked mechanism 3 is driven using gear 30, and the gear 30 includes
Gear 31 and gear soft layer 32, gear soft layer 32 cover 31 surface of gear.
Simultaneously lock tongue guide rod 1 is additionally provided with muting pad 10 with one end end that lock tongue connecting rod 2 is not connected.The gearing
Mechanism 3 includes gear 30 and the interconnecting piece 4 with the cooperation of gear 30, and interconnecting piece 4 is arranged in lock tongue guide rod 1 and lock tongue connects
Bar 2 is held in opposite directions, and the matched rack gear 41 of gear 30 is provided on interconnecting piece 4, and the gear 30 is then by being set in glove box
On the connecting column 42 of plate protrusion.Bearing can be added between connecting column 42 and gear 30.
And it is provided with balance wing 52 on the lock tongue guide rod 1 and lock tongue connecting rod 2, is provided in the balance wing 52 and bullet
Property the connecting hole 53 that connects of element 51, the elastic element 51 is using conventional extension spring.
Unlock piece (not shown) drives lock tongue guide rod 1 mobile to 2 direction of lock tongue connecting rod in use, so that lock
One end that tongue guide rod 1 is connected with interlinked mechanism 3 is also mobile to 2 direction of lock tongue connecting rod, is driven using gear 30 so that lock tongue connecting rod 2
The one end being connected with interlinked mechanism 3 is mobile to 1 direction of lock tongue guide rod, i.e., both lock tongue connecting rod 2 and lock tongue guide rod 1 move toward one another,
The two can be realized to be located remotely from each other with lock one end, to achieve the purpose that unlock.In unlocking process, since gear 30 passes
It is dynamic, so that gear 30 is in rotation process in entire unlocking process, and contacted with rack gear 41, in addition automobile is in driving process
It is middle exist jolt situation so that gear 30 and rack gear 41 will appear abnormal sound during cooperating, to generate fuzz tone, thus I
Gear 30 is provided with gear soft layer 32 by department, and certain squeeze is played by gear soft layer 32 and is buffered, the two matches more
Rationally, the generation of noise is avoided.
In a particular embodiment, the gear 31 is prepared using ABS material, and gear soft layer 32 then uses TPU
Material preparation, is integrally formed, and 31 thickness of gear formed after injection molding is constant using quadric injection mould.The gear soft layer
32 with a thickness of H4, the diameter of 30 maximum of gear is D1, then D1 >=10H4.
Its middle gear 30ABS material selects the odd beauty ABS in Taiwan, and injection temperature is controlled at 205 ± 10 DEG C, and mold temperature exists
73 ± 3 DEG C, injection volume is controlled the 70% of standard injection amount.Quadric injection mould TPU is carried out after gear 31 is molded completion cooling
.Wherein soft layer with a thickness of 1-2mm, 30 maximum gauge of gear is 2cm, the number of teeth 80.
The thickness of the technique and 30 diameter of gear and soft layer that are prepared by control gear 30 is to following example 1-5
It is tested and (does not add muting pad 10).
Above-mentioned conclusion (of pressure testing) can be seen that the antiwear characteristic of TPU increases as its thickness increases, but soft layer thickness
The section 1.2-2mm influences less, to be thought of as reducing noise, then thickness that can be preferably 1.2-2mm sections matches, and optimal selection is
1.5mm, one reason are in manufacturing process can there is a little error, and median is selected finally to prepare actual result still in model
It encloses, secondly reason is that the 1.5mm cost that in contrast the two is molded is relatively low.
In a particular embodiment, the muting pad 10 is prepared using EPDM material, is passed through with 1/ lock tongue connecting rod 2 of lock tongue guide rod
Quadric injection mould links into an integrated entity.
Wherein thickness H1 of the muting pad 10 far from 3 side of interlinked mechanism, the thickness H2 close to 3 side of interlinked mechanism, intermediate thickness
Spend H3, the diameter D2 of muting pad 10, then H2 >=H1 >=H2/2 >=H3, and 2 (H1+H2+H3)≤D2≤5 (H1+H2+H3).It is preferred that
Ground, the diameter of D2 are 15-20mm, then H1 is 1.2-2.4mm, H2 3-4mm, H3 0.7-1.1mm.
The thickness of the technique and 30 diameter of gear and soft layer that are prepared by control gear 30 is to following example 1-5
It is tested and (adds muting pad 10).
Above-mentioned conclusion (of pressure testing) can be seen that H1 increases and lower noise with its thickness, but H2 influences in the section 3.2-3.8mm
Less, be thought of as reducing noise, then can thickness that preferably H2 is 3.2-3.8mm sections match, optimal selection 3.4mm,
One reason is in manufacturing process can there is a little error, and median is selected finally to prepare actual result still in range, secondly
Reason is that the smaller material requested of thickness is fewer, and cost is relatively low.
The unlock piece not shown in figure is a kind of common structure, attached drawing in specific visible patent 201420649908.0
2。
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
