Abstract

The utility model relates to a detachable helmet wiper, which comprises a driving mechanism (1) and a wiper, wherein a skin suction cup (11) which is adsorbed on the top portion of a helmet is arranged on the bottom surface of an outer shell of the driving mechanism, a helical gear (13) is arranged on a motor shaft which is arranged in the outer shell of the driving mechanism, the helical gear (13) is meshed with a step-by-step variable gear (14), and which is movably connected with an internal rocker (2) through a connecting rod (15). The wiper comprises an external rocker (5) and a wiper bar (7) which is movably connected with the external rocker, the end of the wiper bar is connected with a screen wiper (9) through a fixed frame, the external rocker (5) is connected with the internal rocker (2) of the driving mechanism through a detachable arm (3), the internal rocker is driven by a motor driving variable gear to do a left and right reciprocating motion, thereby the screen wiper back and forth brushes rain on a veil of the helmet. The utility model has small volume, beautiful shape, convenient operation, excellent rain brushing effects.

Description

Dismountable type helmet wiper

Technical field

The utility model relates to a kind of wiper, particularly is exclusively used in the helmet wiper of removing faceplate rainwater and fog winter.

Background technology

In a single day the Motor-cyclist meets rain, mist, snow weather in winter, rainwater, fog that the most worried is exactly keeps out the wind on the face shield block sight line, the dimness of vision easily, and influence is normally travelled, and also easily causes traffic accident.It's raining and blowing hard especially if lift the face shield that keeps out the wind, and raindrop is beaten on the face not only painful but also cold, equally also feels bad.Existing helmet windshield wiper complex structure, driving mechanism generally is positioned over the inner chamber at helmet top, has taken the helmet inner chamber confined space undoubtedly, and to the helmet manufacturing makes troubles, increase manufacturing cost, even reduce the safety coefficient of the helmet, the helmet that has come into the market also inconvenience is transformed; Rain brush is an arc overall structure, keeps out the wind the face shield applying not exclusively closely with the helmet, blows the rain poor effect.

Summary of the invention

The purpose of this utility model is in order to address the above problem, and provide that a kind of volume is little, good looking appearance, easy to use, to blow rain effective, directly is adsorbed on the helmet, need not to change the dismountable type helmet wiper of helmet structure.

The technical scheme that the utility model is taked: a kind of dismountable type helmet wiper comprises driving mechanism and wiper, driving mechanism is installed on the helmet, wiper connects driving mechanism and cooperates with faceplate, wiper comprises an external rocking arm and the rain scraping rod that flexibly connects with external rocking arm, the terminal rain brush that flexibly connects of rain scraping rod, described driving mechanism comprises on the interior motor shaft of shell installs helical gear, helical gear and step-by-step variable gear engagement, change-speed gearing flexibly connects built-in rocking arm through connecting rod, described built-in rocking arm is connected with the external rocking arm of wiper through shirking support arm, and driving mechanism shell bottom surface is provided with the suction leather cup and is adsorbed in helmet top.

Rain brush is installed on the fixed mount that flexibly connects with rain scraping rod, and rain brush is a rain brush or many rain brush groups that link, and the rain brush center, two ends of rain brush group is connected on the fixed mount, and the rain brush back side in stage casing is provided with the tensioner spring that embeds in the fixed mount; Be connected extension spring between external rocking arm and the rain scraping rod; Shirk support arm and be provided with the telescopic adjustment hole.

The advantage of this dismountable type helmet wiper is: the wiper electrical machinery of active force is owing to adopt helical gear to make the horizontal placement of motor energy, greatly reduce the overall height of drive mechanism housing, dwindle volume, adopted helical gear can reach the purpose of disposable significantly reduction of speed; All adopt gear drive, non-slip, working stability; At external rocking arm and rain scraping rod moving fulcrum place the moderate extension spring of pulling force is housed, makes rain brush be close to windshield all the time; Rain brush adopts segment design, and it changes and change along with the faceplate arc, is applicable to that the rain brush of the requirement, particularly stage casing of the different cambered surfaces of faceplate is furnished with the tensioner spring, makes rain brush more can good coincideing be arranged with face shield, reaches the best rain purpose of blowing; The support arm that shirks that is connected with external rocking arm is provided with a plurality of telescopic adjustment hole, desired span when rain is blowed in convenient adjusting; Adopt strong rubber to inhale leather cup on driving mechanism and hold helmet top, one inhales and can use, and has both shirked conveniently, need not to change helmet structure again, its volume is little, and shell can be different shape, pattern color according to moulding, the colour planning of the helmet, makes the helmet more attractive in appearance.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model driving mechanism internal structure schematic diagram.

Among Fig. 1, Fig. 2, driving mechanism 1, built-in rocking arm 2 shirks support arm 3, telescopic adjustment hole 4, external Rocker arm 5, extension spring 6, rain scraping rod 7, fixed mount 8, rain brush 9, tensioner spring 10 is inhaled leather cup 11, motor 12, helical gear 13, change-speed gearing 14, connecting rod 15.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in detail.

A kind of dismountable type helmet wiper as shown in Figure 1, comprise driving mechanism and wiper, driving mechanism 1 shell bottom surface is provided with suction leather cup 11 and is adsorbed in helmet top, wiper comprises an external Rocker arm 5 and the rain scraping rod 7 that flexibly connects with external rocking arm, the rain scraping rod 7 terminal fixed mounts 8 that flexibly connect, connect segmented rain brush 9 on the fixed mount, the rain brush back side in stage casing is provided with the tensioner spring 10 that embeds in the fixed mount, be connected extension spring 6 between external Rocker arm 5 one end and the rain scraping rod 7, make its rain brush along with its surface is close in the variation of face shield all the time, the other end is connected with the built-in rocking arm 2 of driving mechanism through shirking support arm 3, shirk support arm 3 and be provided with telescopic adjustment hole 4, can wiper conveniently is connected with driving mechanism or shirk by shirking support arm, the also conveniently adjusted desired span of wiper when blowing rain.

Among Fig. 2, helical gear 13 is installed on the motor shaft in driving mechanism 1 shell, helical gear drives multi-stage gear 14 and carries out reduction of speed three times, make gear have desirable power to drive built-in rocking arm 2 left and right reciprocating motions by moving fulcrum, thereby make rain brush 9 on faceplate, blow rain back and forth through connecting rod 15.
