By means of the footboard with the structure, a four-connecting-rod mechanism is formed by arranging the footboard seat, the main footboard, the auxiliary footboard and the footboard cover which are connected end to end in the pivoted mode, the restoring speed of the unfolded main footboard is controlled through the slow restoring mechanism, and the unfolding angle of the main footboard is limited by the limiting mechanism, so that the slow and automatic folding purpose is achieved, the folding and unfolding processes are smooth without noise, and high user-friendliness is achieved.
Description
Technical field
The present invention relates to a kind of can the pedal that folds of automatic slowly.
Background technology
In sleeping car railway carriage or compartment, passenger generally needs to climb up upper berth and middle berth by pedal, pedal is generally arranged on the sidewall of passage, existing pedal generally needs manually to launch and fold, but passenger generally can forget and folded by pedal after entering bed, make pedal active channel space, phenomenon of easily colliding with, there is potential safety hazard, the experience sense reducing passenger is subject to; For this reason, also have the pedal of energy automatic retracting on the market, but the pedal of existing energy automatic retracting is generally folded by a spring, it folds, and speed, noise are comparatively large, expansion is inconvenient, and passenger's experience is poor.Based on above reason, the invention provides a kind of can the pedal that folds of automatic slowly.
Summary of the invention
In order to solve the problem, the invention provides a kind of can the pedal that folds of automatic slowly.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of can the pedal that folds of automatic slowly, comprise pedal base, main pedal, secondary pedal, pedal cover and return mechanism at a slow speed, the head and the tail pivot joint successively of described pedal base, main pedal, secondary pedal, pedal cover, return mechanism one end and pedal base pivot joint at a slow speed, the other end and secondary pedal pivot joint, main pedal, secondary pedal, pedal cover can relatively launch and fold by pedal base; Also comprise one for limiting the stop gear of pedal base, main pedal, secondary pedal, pedal cover expanded angle.
Described return mechanism is at a slow speed set to can rapid desufflation and the damping air spring that launches at a slow speed.
Described pedal base, main pedal, secondary pedal and damping air spring form a four-bar linkage, when the relative pedal base of main pedal, secondary pedal, pedal cover launches, damping air spring is compressed gradually, when damping air spring is compressed to end position, move in the direction that this four-bar linkage can not launch along main pedal, secondary pedal, the relative pedal base of pedal cover again, four-bar linkage now forms stop gear.
Described stop gear comprises the stay bearing plate being arranged on pedal base one end, and stay bearing plate is positioned in the path of motion of pedal cover.
Pivot points and the pedal cover of described damping air spring and pedal base overlap with the pivot points of pedal base.
It is vertical with pedal base after described main pedal launches.
Described pedal covers in one end and is provided with groove for holding secondary pedal.
Described secondary pedal upper surface is provided with the curved surface of an inner concave shape, and this curved surface is provided with anti-slip veins.
Described pedal base is provided with the containing cavity for holding main pedal.
The invention has the beneficial effects as follows: adopt the present invention of said structure by arranging the head and the tail pedal base of pivot joint, main pedal, secondary pedal, pedal cover form a four-bar linkage, and by return mechanism at a slow speed control main pedal launch after the speed of return, the angle of main pedal expansion is limited by stop gear, reach the object of slow automatic retracting, process of taking down the exhibits smooth noiselessness, very hommization.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the generalized section that the present invention folds;
Fig. 2 is expansion schematic diagram of the present invention;
Fig. 3 is expansion generalized section of the present invention.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 3, the present invention be a kind of can the pedal that folds of automatic slowly, comprise pedal base 1, main pedal 2, secondary pedal 3, pedal cover 4 and return mechanism at a slow speed, the head and the tail pivot joint successively of pedal base 1, main pedal 2, secondary pedal 3, pedal cover 4, return mechanism one end and pedal base 1 pivot joint at a slow speed, the other end and secondary pedal 3 pivot joint, main pedal 2, secondary pedal 3, pedal cover 4 can relatively launch and fold by pedal base 1, vertical with pedal base 1 after main pedal 2 launches, pedal base 1 is arranged on the sidewall of couchette; Secondary pedal 3 upper surface is provided with the curved surface 6 of an inner concave shape, and this curved surface 6 is provided with anti-slip veins, and secondary pedal 3 after deployment curved surface 6 and main pedal 2 upper surface seamlessly transits, and secondary pedal 3 keeps state upward at whole expansion process middle surface 6; Also comprise one for limiting the stop gear of pedal base 1, main pedal 2, secondary pedal 3, pedal cover 4 expanded angle.Adopt the present invention of said structure by arranging the head and the tail pedal base 1 of pivot joint, main pedal 2, secondary pedal 3, pedal cover 4 form a four-bar linkage, and control by return mechanism at a slow speed the speed that main pedal 2 launches rear return, the angle of main pedal 2 expansion is limited by stop gear, reach the object of slow automatic retracting, process of taking down the exhibits smooth noiselessness, very hommization.
Wherein, at a slow speed return mechanism can be set to can rapid desufflation and the damping air spring 5 that launches at a slow speed; Damping air spring 5 is provided with a class check valve in inside, to realize rapid desufflation and to launch at a slow speed.
As shown in the figure, pedal base 1, main pedal 2, secondary pedal 3 and damping air spring 5 form a four-bar linkage, when the relative pedal base 1 of main pedal 2, secondary pedal 3, pedal cover 4 launches, damping air spring 5 is compressed gradually, when damping air spring 5 is compressed to end position, this four-bar linkage can not move along main pedal 2, secondary pedal 3, pedal cover 4 direction that pedal base 1 launches relatively again, and four-bar linkage now forms stop gear.Utilize damping air spring 5 to coordinate with main pedal 2, secondary pedal 3, pedal cover 4 and form stop gear, and can carry out supporting role when passenger tramples main pedal 2 to main pedal 2, structure is ingenious simple, compact.
The embodiment of certain stop gear does not limit to said structure, and such as stop gear also can adopt following embodiment, comprises the stay bearing plate being arranged on pedal base 1 one end, and stay bearing plate is positioned in the path of motion of pedal cover 4.Directly carry out support limit to the pedal cover 4 after expansion by stay bearing plate, structure is simple.
As shown in the figure, the pivot points of damping air spring 5 and pedal base 1 and pedal cover 4 overlap with the pivot points of pedal base 1.The moment that setting like this can make damping air spring 5 act on when return on secondary pedal 3 is larger, makes return more smooth and easy; This structure can make result of the present invention more compact simultaneously, and profile is more small and exquisite.
As shown in the figure, pedal cover 4 is provided with the groove 7 for holding secondary pedal 3 in one end; Pedal base 1 is provided with the containing cavity 7 for holding main pedal 2; Setting like this can reduce volume shared by the present invention, release sleeping carriage channel space.
Above-described embodiment is preferred version of the present invention, and the present invention also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the scope set by the application's claim.
