Abstract
The utility model discloses a vehicle and a windscreen wiper thereof. The windscreen wiper comprises a wiper arm, a slide rail and a cam. The wiper arm is arranged on the cam through the slide rail, a spring is connected to the wiper arm, a spring groove used for containing the spring is formed in the slide rail, and the slide rail drives the wiper arm to slide in the cam under the driving of external force. Compared with a traditional windscreen wiper, the length of the wiper arm at the initial position is reduced, the wiper arm can be hidden in a rear edge of a cover conveniently, and therefore appearance beautification is realized. In the running process, the wiper arm can realize stretching and contracting automatically and the wiping and brushing area can be effectively increased.
Description
Technical field
The utility model belongs to vehicle technology field, particularly relates to a kind of vehicle and wiper thereof.
Background technology
Windscreen wiper, as the important functional component of vehicle, plays outstanding effect to the driving safety of vehicle.In design process, the longer the better for the scraping arm of windscreen wiper, to realize large as far as possible wiping area.Situation about being placed in inside rear-view mirror seat for rain sensor is all the more so, laws and regulations requirement due to front windshield glass transparent region, the position of inside rear-view mirror is generally higher, and wiper arm is scraped the normal work that rain sensor just can make rain sensor that must scrape, so windscreen wiper more needs there is certain length.But be subject to the restriction in moulding and space, the wiper arm that meets length requirement mostly cannot be hidden in completely after car bonnet along under, had a strong impact on the attractive in appearance of moulding.
Traditional windscreen wiper adopts the wiper arm of fixed length, and for meeting functional requirement, scraping arm design is longer, be not easy to arrange and car load attractive in appearance.
Utility model content
In order to solve the length of the windscreen wiper on existing vehicle, cannot adjust, can not meet multi-functional demand.
In order to solve the problems of the technologies described above, the utility model provides a kind of wiper, comprise: wiper arm, slide rail and cam, described wiper arm is arranged on cam by described slide rail, on described wiper arm, be connected with spring, described slide rail is provided with for placing the spring groove of described spring, and described slide rail drives described wiper arm to slide in cam under external force drives.
Preferably, the first end of described spring is connected on wiper arm by the first spring perch, is provided with the second spring perch in described spring groove, and the second end of described spring is connected with the second spring perch contact.
Preferably, described slide rail is provided with the connecting bore for being connected with axle drive shaft.
Preferably, described slide rail is provided with the chute for sliding for wiper arm.
The utility model also provides a kind of vehicle, comprises described wiper.
The scalable wiper that the utility model is set forth, the principle of work of employing cam pair and sliding pair, in the process of wiper arm rotation, scrapes arm lengths by automatic adjustment.Under same initial position length, this wiper arm is compared with traditional wiper arm, and the wiping area of motion process is larger, and the windscreen wiper length under each movement position is determined to have better design flexibility by cam face, can meet more functions expanding demand.Specifically there is following effect:
(1) can significantly increase the wiping area of windscreen wiper, improve the safety of travelling;
(2) under initial position, scraping arm shrinks, and length is shorter, can be hidden in after cover along under, outward appearance is more attractive in appearance;
(3) arm lengths of scraping under each movement position is determined to have better design flexibility by cam face.

Fig. 1 is the overall schematic of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of the utility model slide rail;
Fig. 3 is Fig. 2 partial enlarged drawing;
The lateral plan of Fig. 4 Fig. 3;
Fig. 5 is the schematic diagram of the utility model the first state;
Fig. 6 is the schematic diagram of the utility model the second state.
In figure: 1 wiper arm, 2 slide rails, 3 cams, 4 hinges, 5 springs, 6 first spring perches, 7 chutes, 8 second spring perches, 9 spring grooves, 10 connecting bores.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, overall schematic for a kind of embodiment of the utility model, this wiper comprises wiper arm 1, slide rail 2 and cam 3, described wiper arm 1 is arranged on cam 3 by slide rail 2, between described wiper arm 1 and slide rail, by spring, be connected, the first end of described wiper arm 1 contacts with the surface of cam; Described slide rail drives described wiper arm to slide in cam under external force drives, and makes the differing heights position of the second end of wiper arm 1 in Windshield.
Compare traditional wiper, reduced the length of initial position wiper arm, be convenient to wiper arm be hidden in after cover along in, realize beautifying of outward appearance.In motion process, wiper arm can be realized flexible automatically, can effectively increase wiping area.Wiper arm length under each movement position is determined by cam face, for design provides alerting ability.
As in Figure 2-4, this slide rail 2 is provided with for placing spring groove 9 and the chute 7 of spring, wiper arm 1 is arranged on cam 3 through chute 7, spring 5 is placed in spring groove 9, and be connected with wiper arm 1, this wiper arm 1 produces returning place force, compresses with cam 3, makes wiper arm 1 have the propulsive effort of return.On slide rail 2, be also provided with connecting bore 10, this connecting bore 10 is connected with axle drive shaft, under the drive of axle drive shaft, moves.The connecting bore 10 of this embodiment is splined hole, to be connected with the axle drive shaft of wiper, under the driving of axle drive shaft, moves, and consults Fig. 4.On this slide rail, be also provided with hinge 4, one end of chute 7 is connected with wiper arm 1 by hinge 4.
The first end of this spring 5 is connected on wiper arm 1 by the first spring perch 6, is provided with the second spring perch 8 in spring groove 9, and the second end of spring 5 is connected with the second spring perch contact.
As Fig. 5, when the first state, the first end of wiper arm 1 is in extreme lower position on cam, and now wiper arm is shortest length.As shown in Figure 6, when the second state, when the first end of wiper arm 1 is in cam higher position, now wiper arm length increases.
Principle of work of the present utility model is: at wiper arm, drive in stroke, windscreen wiper axle drive shaft drives sliding track mechanism 2 to rotate by splined hole, wiper arm 1 rounded back end and cam 3 produce relative motion, 3 pairs of wiper arms of cam, 1 rounded back end produces propelling thrust, make to skid off in the chute 7 of wiper arm 1 from slide rail 2, wiper arm 1 extends.In windscreen wiper axle drive shaft recovery stroke, rely on the restoring force of pull back spring 5, wiper arm 1 rounded back end is contacted with cam 3, and do return motion along cam rail, wiper arm 1 shortens.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
