Abstract
The utility model relates to a silica gel button anti-shedding mechanism for an automobile air conditioner control panel and belongs to the technical field of the automobile air conditioner control panel. The silica gel button anti-shedding mechanism comprises a PCB (printed circuit board) and silica gel buttons arranged on the PCB, wherein a bottom surface of the silica gel buttons is provided with positioning columns, central portions of the positioning columns are inverted boss structures, the PCB is limited and fixed through upper ends of the inverted boss structures after the positioning columns penetrate through positioning holes on the PCB. The silica gel button anti-shedding mechanism for the automobile air conditioner control panel has properties of simple structure and reasonable design, the positioning columns having the inverted boss structures are arranged on the silica gel buttons, so the silica gel buttons are buckled on the PCB board, and thereby shedding of the silica gel buttons is avoided, and secondary assembly is reduced.
Description
Technical field
The utility model belongs to the automobile air conditioner control panel technical field, is specifically related to a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel.
Background technology
Air-Conditioning Control Panel is that the user controls the panel that air conditioner steering mechanism is realized the various functions of air-conditioning indirectly.Function selecting key, temperature key, tune wind key, rear window defrosting key etc. are arranged on automobile air conditioner control panel, by these buttons, with contacting of pcb board, realize various functions.And between pcb board and silica gel button, anti-shedding mechanism is not set in prior art, and therefore, after silica gel push-button and pcb board assembling, in assembling, transportation, easily come off, cause the secondary assembling, affect production efficiency.
The utility model content
The problem existed for prior art, the purpose of this utility model is that design provides a kind of technical scheme of the anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel.
Described a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel, comprise pcb board and be arranged on the silica gel push-button on pcb board, it is characterized in that described silica gel push-button bottom surface is provided with reference column, in the middle part of described reference column, for falling boss structure, described reference column is fixed pcb board is spacing by the described upper end of falling the boss structure after passing the location hole on pcb board.
Described a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel, is characterized in that the described diameter of falling the boss structure is greater than the diameter of reference column top and bottom.
Described a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel, the difference that it is characterized in that described reference column upper end diameter and lower end diameter is 0.3～0.4mm.
Described a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel, is characterized in that described boss structure and reference column upper end are by the arc surface transition arranged.
Above-mentioned a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel, simple in structure, reasonable in design, reference column with boss structure is set on silica gel push-button, make the silica gel push-button left-hand thread on pcb board, thereby avoid silica gel push-button to come off, reduce the secondary assembling.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is silica gel push-button in the utility model.
In figure: the 1-PCB plate; The 2-silica gel push-button; The 3-reference column; 301-falls boss structure; The 302-arc surface.
Embodiment
Further illustrate the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel comprises pcb board 1 and is arranged on the silica gel push-button 2 on pcb board 1.Wherein silica gel push-button 2 bottom surfaces are provided with reference column 3.Reference column 3 middle parts are for falling boss structure 301, and boss structure 301 diameters that fall are greater than the diameter of reference column 3 top and bottom, fall boss structure 301 and reference column 3 upper ends by arc surface 302 transition that arrange.When pcb board 1 and silica gel push-button 2 cooperation, pass through boss structure 301 upper ends after the location hole that reference column 3 passes on pcb board 1 pcb board 1 left-hand thread is realized the spacing of pcb board 1 fixed.For the ease of die sinking, the difference of reference column 3 upper end diameter and lower end diameter is designed to 0.3～0.4mm.
Above-mentioned a kind of anti-shedding mechanism of the silica gel push-button for automobile air conditioner control panel, simple in structure, reasonable in design, reference column 3 with boss structure 301 is set on silica gel push-button 2, make silica gel push-button 2 left-hand threads on pcb board 1, thereby avoid silica gel push-button to come off, reduce the secondary assembling.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
