The instrument front frame is installed on the circuit board through the light guide support, and the contact switch is welded on a switch contact of the circuit board. One end of the button is inserted into the light guide support and is opposite to the contact switch. The light guide support comprises a protection ring sleeved outside the contact switch, and the protection ring and the supporting part of the light guide support are integrally connected through ribs. The part, of the button, inserted into the instrument front frame is provided with a flange stretching out in the radial direction, one end of the cylindrical pressure spring playing a role in button reset is pressed under the flange, and the other end of the cylindrical pressure spring presses on the ribs. According to the utility model, each part of the elastic press button structure is uniformly forced, and is not liable to damage and fail, and the service life of the button is substantially prolonged. The elastic press button structure is simple and stable, and is advantaged by comfortable feel.
Description
Technical field
The utility model belongs to automobile instrument field, relates to a kind of elastic button structure.
Background technology
Instrument button is indispensable part in instrument, is mainly used in regulating data, switching Presentation Function state on LCD screen, adjusts setting and the mileage mode-conversion of time, thereby has guaranteed the normal demonstration of instrument various functions.
But, in the process that traditional automobile combination meter button uses in reality, there will be many problems.Changing along with the prolongation of service time by bonding force of button, push-button reset is not thorough, and even instrument button lost efficacy.As shown in Figure 2, main cause is that conventional button structure increases spiral engraved structure 9 on light guide support, thereby has increased the elasticity at this place; Button is placed on light guide support, by button, spiral engraved structure 9 is exerted pressure, and make spiral engraved structure 9 produce deformation, thereby produce stroke, although this is simple in structure, Shortcomings part.
This engraved structure is carried out to force analysis known, the stressed rear generation deformation of light guide support.And for working of plastics, uneven due to part stress, at deformation quantity larger part, be prone to cracking, therefore button lost efficacy.The problem occurring for fear of conventional instrument press-button structure need to be carried out Improvement and perfection on the basis of former instrument button.
Utility model content
The utility model provides a kind of elastic button structure, and object is to avoid the elastic component playing reset role because unbalance stress damages, and extended the useful life of button.
To achieve these goals, the technical scheme that the utility model is taked is:
Described elastic button structure, button before comprising circuit board, the front frame of instrument and being arranged on described instrument on frame, the part that described button stretches in the front frame of described instrument is provided with radially-protruding flange, described flange below is provided with spring cupport structure, described spring cupport structure is fixedly connected with frame before described instrument, and described flange is connected with described spring cupport structure by the cylinder stage clip playing reset role.
Before described instrument, frame is arranged on described circuit board by light guide support, and the through-hole wall of described light guide support is provided with at least three ribs that stretch out inwardly, and the external part of described rib is all connected on a guard ring, and described spring cupport structure is described rib.
The switch contact of described circuit board is positioned at described guard ring, and the height of described guard ring is greater than described rib, and one end that described cylinder stage clip is pressed on described rib is enclosed within outside described guard ring.
The diameter of described flange is greater than the diameter of key hole on the front frame of described instrument.
When described elastic button structure is in the normal state, described cylinder stage clip is in pressured state.
The shape size of described flange and the through hole of described light guide support are suitable.
On the switch contact of described circuit board, be welded with contact-making switch.
Adopt technique scheme, press-button structure each several part is stressed evenly, and not fragile inefficacy has extended useful life of button greatly.Press-button structure simple and stable, comfortable feel.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of elastic button structure of the utility model;
Fig. 2 is the structural representation of conventional button structure in background technology.
Being labeled as in figure:
1, frame before instrument; 2, flange; 3, cylinder stage clip; 4, rib; 5, contact-making switch; 6, guard ring; 7, button; 8, light guide support; 9, spiral engraved structure.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
As shown in Figure 1, the utility model provides a kind of elastic button structure, the spiral engraved structure 9 that uses cylinder stage clip 3 to substitute in background technology, and concrete structure comprises the front frame 1 of instrument, cylinder stage clip 3, contact-making switch 5, light guide support 8, button 7 and circuit board.Before instrument, frame 1 is arranged on circuit board by light guide support 8, is welded with contact-making switch 5 on the switch contact of circuit board.Button 7 is cylindrical, is arranged on the front frame 1 of instrument, and insert in light guide supports 8 button 7 one end, facing to the mini button on contact-making switch 5.
In the through hole of light guide support 8, be connected with rib 4 and guard ring 6.Contact-making switch 5 is positioned at guard ring 6 centers, and guard ring 6 is connected as a single entity by rib 4 with the through-hole wall of light guide support 8.Button 7 inserts the part in frame 1 before instrument and is provided with radially-protruding flange 2, and the diameter of flange 2 is greater than before instrument the diameter of key hole on frame 1, therefore button 7 can be stuck in before instrument in frame 1 to the bayonet arrangement that only button 7 departs from of also can separately setting up defences.On the other hand, play cylinder stage clip 3 one end of button 7 reset responses below flange 2, the other end is pressed in above rib 4.The height of guard ring 6 is greater than the height of rib 4, and the bottom of cylinder stage clip 3 is enclosed within outside guard ring 6, prevents that it from moving, protective circuit plate.Button 7 is connected with rib 4 by cylinder stage clip 3, and each rib 4, at sustained height, makes cylinder stage clip 3 each several parts stressed evenly, and flange 2 and rib 4 are also all stressed even on the contact-making surface with cylinder stage clip 3, thereby avoid unbalance stress to cause button to damage.
The through hole of the shape size of flange 2 and light guide support 8 is suitable, and this can prevent that button 7 from rocking.Under this elastic button structure place normality, the distance between flange 2 and rib 4 is still less than the drift of cylinder stage clip 3, and cylinder stage clip 3 is all the time in pressured state.This makes button 7 under normal conditions, does not also have axial becoming flexible.Make user's feel better, also more reliable and more stable.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection range of the present utility model.
