Abstract
Provided is an interface fixing member structure for an automobile navigator. At least one fixing member capable of fixing an interface to a substrate is disposed. At least one elastic clamping member is disposed on the fixing member and along a contact surface of the fixing member and the interface. According to the interface fixing member structure for an automobile navigator, the elastic clamping member, namely a deformable bump elastic structure, is applied to the interface fixing member. Interface fabrication tolerance is absorbed by the deformation of the elastic clamping member. Thus, the interface is completely pressed and interface protrusions caused by wave-soldering of the substrate are prevented. In addition, the elastic clamping member can be produced as a detachable structure and is simple in structure and easy to achieve serialized and standardized production. The elastic clamping member can be used as an industrial standard member so as to further improve the quality of the automobile navigator and has good practical value.

Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Traditional substrate interface or do not have panel beating to push down, that panel beating is directly pushed down multiple interfaces, like this in the time that substrate is crossed this procedure of wave-soldering, because the crest scouring force of tin stove acts on the stitch of interface, and cause interface to float, thereby affect the fastness of interface and the centering with bonnet, and then affect the lifting of quality and the quality of whole automobile navigation instrument.The utility model improves for this situation docking port anchor structure just, in interface mount structure, set up deformability salient point elastic construction, utilize the distortion of this elastic construction to absorb interface manufacturing tolerance, interface is killed completely, and be unlikely to occur that interface floats when substrate is crossed wave-soldering.
embodiment 1
Concrete, a kind of interface mount structure of automobile navigation instrument, referring to Fig. 1-Fig. 5, is at least provided with one interface 10 is placed in to the claw 30 on substrate 20, and along being at least provided with a flexible clamp piece 40 on the contact-making surface of itself and interface 10.This flexible clamp piece 40 can carry out self-control according to the tolerance of interface.
In the present embodiment, described flexible clamp piece 40 is made into integration with interface mount structure.Meanwhile, described flexible clamp piece 40 is provided with salient point 41.In this scheme, this flexible clamp piece is that to be fixed at interface mount structural.
embodiment 2
In the present embodiment, in order to simplify, technique is convenient makes, and described flexible clamp piece 40 is demountable structure.Referring to Fig. 6-Fig. 9, for attractive in appearance, and do not affect miscellaneous part, described flexible clamp piece 40 has a U-shaped structure 42, U-shaped structure 42 forms fixed-wing 43 to both sides horizontal-extending, the bottom of this U-shaped structure 42 is provided with contact flat spring 44, and fixed-wing 43 is for being fixed on interface mount structure by this flexible clamp piece 40.Corresponding, on the contact-making surface of interface mount structure and interface 10, the place of the fixed-wing 43 of corresponding flexible clamp piece 40 is provided with draw-in groove 50, and fixed-wing 43 and this draw-in groove 50 of described flexible clamp piece 40 forms the clamp structure of upper and lower holding.
In addition, for convenience of making, in the present embodiment, the bottom of described U-shaped structure 42 is a plane.Meanwhile, absorb the tolerance that interface 10 is manufactured in order further to ensure by the distortion of flexible clamp piece, described contact flat spring 44 is provided with salient point 441.
The utility model, on the basis of present interface mount, has increased deformability salient point elastic construction, utilizes the distortion of this elastic construction to absorb interface manufacturing tolerance, interface is killed completely, and be unlikely to occur that interface floats when substrate is crossed wave-soldering.
Of the present utility model to realize principle process as follows: in the time that interface mount is pushed down interface, under perfect condition, the salient point of flexible clamp piece and interface have the magnitude of interference of 0.8mm.In the time that interface mount is pushed down interface, if interface height dimension tolerance is accomplished lower limit-0.4 o'clock, salient point is just pushed down completely, and contact flat spring there will not be distortion; In the time that interface height dimension tolerance is 0, thus contact flat spring up perk 0.4mm push down interface; In the time that interface height dimension tolerance is accomplished the upper limit+0.4, thus contact flat spring up perk 0.8mm push down interface.Therefore, interface mount can realize self-control according to the tolerance of interface.
In concrete manufacturing process, A, the B size of the length width of flexible clamp piece are determined as follows: for ensureing sheet metal component mouldability reliability and economy, suggestion B is of a size of 2.5-3.5 times of thickness of slab, and A is of a size of 5-7 times of thickness of slab, and thickness of slab is 0.8-1.0mm.Material suggestion is used the sub-plumbous galvanized steel plain sheet of SECC electrolysis, and the actual trade mark can be selected according to conductivity and solderability.
In addition, the quantity of flexible clamp piece select and structural strengthening scheme as follows: because contact flat spring can produce flexural deformation in the time pushing down interface, at this moment whole interface mount intensity determines whether the tightening force of interface mount claw can pass on each contact flat spring, and whether the holding capacity of claw is enough.Therefore it is as follows that contact flat spring quantity, interface mount length and claw structure adopt recommendation:
| Interface mount length L (mm) | Contact flat spring quantity (individual) | Claw structure quantity (individual) |
| 60≤L＜80 | ≤3 | 2 |
| 80≤L＜100 | ≤3 | 2 |
| 100≤L＜120 | ≤4 | 3 |
| 120≤L＜140 | ≤5 | 4 |
| 140≤L＜150 | ≤6 | 4 |
Note: when interface mount length L size exceedes 150mm, the whole intensity of interface mount a little less than, and manufacturing tolerance be difficult to ensure, do not advise use.
In actual fabrication process, the flexible clamp piece relative dimensions relational expression of interface mount structure is as follows:
WL^2=(768nEBt^2)/(15A^3?)
Referring to Figure 10, in relational expression:
1. .W is interface mount width, the m of unit;
2. .L is interface mount length, the m of unit;
3. the quantity that .n is flexible clamp piece;
The modulus of elasticity of the material that 4. .E is interface mount, units MPa;
5. .B is flexible clamp piece width, the m of unit;
6. the thickness that .t is interface mount, unit is m;
7. .A is flexible clamp piece jib-length, and unit is m.
In above relational expression, selecting of each variable can adopt the 2nd, 3 recommended amounts, also can select according to actual design condition.In concrete manufacturing process, can adjust by adjusting size A, B the deformation force of this structure.
In addition, for detachable flexible clamp piece, for highly differing larger interface, and product for producing in enormous quantities, can, by adjusting differing heights H seriation, standardized production, form industry standard part.The principle of work and power of detachable flexible clamp piece is to be fixed by the draw-in groove shown in flexible clamp piece and Fig. 7 of Fig. 6, realizes interface and compresses and fix.Building block principle as shown in Figure 8, fixes cooperation by two salient points of interface mount and two waist holes of detachable flexible clamp piece, after assembling as shown in Figure 9.From economic considerations, suggestion realizes industry standardization and produces this constructional device.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection range of the present utility model.
