Abstract
The utility model discloses an installation structure of a collapse type knob. The installation structure of the collapse type knob comprises a control panel, a knob, and a circuit board. Arc wiring ducts and ribs between the arc wiring ducts are provided on the circuit board. A cavity into which the knob is sunk when the ribs are fractured on the condition that a pressure is greater than or equal to a predetermined pressure is arranged at the position under the circuit board. A soft cushion ring which is torn up when the knob is collapsed is provided between the control panel and the circuit board. An inner side of the soft cushion ring is connected to a bottom portion of the knob. An outer side of the soft cushion ring is clamped and connected between the control panel and the circuit board. The arrangement of the soft cushion ring slows down the collapsing speed of the knob, generates an energy-absorbing effect, reduces the impact force of the human body on the knob and the control panel, and prevents people from being hurt by the hard collision. The soft cushion ring is fixed between the control panel and the circuit though the clamping method, the traditional screw connection method is changed, the cost is saved, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially relates to a kind of crumple formula knob mounting structure with collision energy-absorbing effect.
Background technology
The members such as knob, button and switch of locational each protrusion of Auto Instrument desk damage human body when collision happens easily.According to GB standard GB 11552-2009, crew module's internal structure (except the inside rear-view mirror), controls, top cover or removable top cover, backrest and seat rear part are all stipulated aspect the ridge.Wherein, When these members protrusion panel board surface height surpass 9.5mm, be not more than the flush end pressure head of 50mm with a diameter, apply the longitudinal horizontal force forward of 378N above that; Should be able to withdraw panel board surface or come off of these members, the height after the withdrawal should be below 9.5mm.In order to reach this standard, some auto vendors directly make the height of panel board upper knob and are lower than 9.5mm, the convenience when this has influenced driver and conductor's action button.
Chinese patent Granted publication number: CN201984989U; At on 09 21st, 2011 Granted publication day; Disclose a kind of crumple formula control handle mounting structure, comprised circuit board and be fixed in the knob on the circuit board, circuit board offers a plurality of arc grooves at the knob lower position; Arc groove surrounds circle; Utilize the circuit board rib to link to each other between the arc groove, the circuit board below is provided with over against knob and can holds the cavity of knob, and the circuit board rib can under more than or equal to the predetermined pressure situation, rupture so that knob portion or all sink down in the cavity.This structure is satisfying under the prerequisite of laws and regulations requirement; Improved the comfort level of controlling of knob; Weak point is that when collision happens, this crumple formula control handle reaches under the predetermined pressure situation in the impact of vertical equity forward that receives, and the moment crumple can take place; The crumple process lacks energy-absorbing function to reduce impact; So human body is when to the impulsive force of knob during greater than predetermined pressure, human body still can continue with crumple after knob and panel board control panel generation hard collision, human body is caused very big injury.
Summary of the invention
The utility model is in order to overcome the deficiency that crumple formula control handle mounting structure of the prior art lacks energy-absorbing function, a kind of crumple formula knob mounting structure with collision energy-absorbing effect to be provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of crumple formula knob mounting structure; Comprise control panel, stretch out control panel knob, be positioned at the circuit board of the connection knob of control panel below; Circuit board is provided with at arc groove below the knob and the rib between the arc groove; Circuit board below has the rib cavity in afterwards knob is lowered into that under more than or equal to the predetermined pressure situation, rupture; Be provided with the software packing ring of when the knob crumple, tearing between said control panel and the circuit board, the inboard of software packing ring connects the knob bottom, and the outside clamping connection of software packing ring is between control panel and circuit board.During the knob crumple, the inboard of software packing ring is downward with knob, and the outside of software packing ring is sandwiched in can be not downward with knob between control panel and the circuit board, and the software packing ring can be torn with the knob crumple.Crumple takes place when receiving the longitudinal horizontal force forward of 378N according to the knob of rules and regulations, the rib fracture on this moment circuit board, the knob height descends; Because the setting of software packing ring; The decline process because of the resistance that receives the software packing ring and tear process slowly, produce energy-absorbing function, impact power partial offset; Reduce knob and the panel board control panel impulsive force of human body after, prevent the injury that hard collision causes human body crumple.
As preferably, said software packing ring is provided with several reference columns that is used for software packing ring location that stretches to control panel, and control panel is provided with the location notch corresponding with reference column.Through reference column and location notch the software packing ring is located, change traditional screw connecting mode, practice thrift cost, improve dismounting efficient.
