The rearview mirror based on the current vehicle generally does not have a windscreen wiper, and mainly adopts manual cleaning of the rearview mirror to achieve the purpose of clearly checking the driving direction of the rear vehicle during driving so as to ensure the driving safety. However, the manual cleaning method is not suitable for rainy days; the existing part of vehicles dry rainwater on the rearview mirror in rainy days by arranging a heating system, but watermarks can be generated to influence the definition of the mirror surface, and potential safety hazards are caused; and for the structure that adopts the motor to drive the wiper, although can clear away the rainwater in rainy day, overall structure needs design waterproof construction to prevent the rainwater to get into the motor to improve the cost of rear-view mirror greatly. The invention provides a rearview mirror windscreen wiper and a vehicle, wherein the elastic part is formed by shape memory alloy, so that a scraping plate of the windscreen wiper is driven to deform and swing, a motor is not required to be installed, a high-cost waterproof structure is not required to be designed, rainwater can be fully cleaned in rainy days, and meanwhile, the manufacturing cost is low.
The following describes the rear view mirror wiper and the vehicle disclosed in the present invention in more detail with reference to the embodiments shown in the drawings.
The rearview mirror wiper disclosed by the invention is shown in figures 1 to 7 and comprises a rearview mirror shell, a rearview mirror 1 and a wiper; when the rearview mirror is installed, the rearview mirror 1 is installed in the rearview mirror shell by adopting the mirror frame 2 shown in figure 1, and the rearview mirror 1 divides the rearview mirror shell into an inner side and an outer side.
In a specific structure, the windscreen wiper comprises a scraping plate 3, a driving device 4 and a first elastic part 5, wherein the driving device 4 is arranged on the inner side of a rearview mirror shell, the scraping plate 3 and the first elastic part 5 are arranged on the outer side of the rearview mirror shell, and the scraping plate 3 is attached to the mirror surface of a rearview mirror 1. When the rearview mirror is assembled, the first elastic part 5 is connected and arranged on the scraping plate 3, and the deformation of the first elastic part enables the scraping plate 3 to have at least a straight state and a bent state on the rearview mirror; the driving device 4 is connected with the end part of the scraper 3 and is used for driving the scraper 3 to swing back and forth around the end part connected with the driving device 4 on the rear view mirror surface; when the scraper 3 swings at the rear-view mirror surface, the scraping cleaning of rainwater on the rear-view mirror surface is realized. In addition, in order to avoid the wiper from occupying the view range of the rear view mirror surface when not in operation and ensure driving safety, as shown in fig. 5, an accommodating groove 6 is arranged on the outer side of the rearview mirror shell adjacent to the vehicle body direction, and when the scraper 3 is in a bent state, the driving device 4 drives the scraper 3 to be accommodated in the accommodating groove 6; simultaneously, as shown in the attached drawing, the scraper 3 and the accommodating groove 6 are designed in the embodiment to be matched in size, so that the whole rearview mirror is attractive.
As shown in connection with fig. 2 to 5, the scraper 3 comprises a first link 3.1 and a second link 3.2 connected at their ends; the connection mode is as follows: one end of the first connecting rod 3.1 is connected with the driving device 4, the other end of the first connecting rod is provided with a first U-shaped groove, the end part of the second connecting rod 3.2 is provided with a second U-shaped groove, and two side walls of the second U-shaped groove are adaptive and hinged to two side walls of the first U-shaped groove. In order to realize that the scraper 3 is driven to change between a straight state and a bending state through the deformation of the first elastic part 5, an installation cavity is formed between the first U-shaped groove and the second U-shaped groove when the first connecting rod 3.1 and the second connecting rod 3.2 are hinged, and the first elastic part 5 is arranged in the first installation cavity. In the embodiment, the first elastic part 5 is a first spring made of a shape memory alloy material, two ends of the first spring are respectively connected to the first U-shaped groove and the second U-shaped groove, and the first spring has a degree of freedom of moving and stretching under a power-on condition. In the figure, a pair of through holes are respectively formed at the bottoms of the hinged positions of the side walls of the first U-shaped groove and the second U-shaped groove, and two ends of the first spring are fixedly connected with the through holes at the bottoms of the side walls of the first U-shaped groove and the second U-shaped groove respectively; of course, both ends of the first spring can be directly and fixedly connected with the bottom surfaces of the first U-shaped groove and the second U-shaped groove respectively.
When first spring takes place deformation, drive first connecting rod 3.1 and second connecting rod 3.2 and alternate the state in articulated position, include: when the first spring extends, the first connecting rod 3.1 and the second connecting rod 3.2 are horizontally connected, and the scraper 3 is in a flat state; when the first spring contracts, the first connecting rod 3.1 and the second connecting rod 3.2 are vertically connected, and the scraper 3 is in a bending state.
For convenient processing, the lens frame 2 is provided with a notch from the middle part of the bottom surface of the rearview mirror shell to the middle part of the side surface close to the vehicle body, and the notch forms an accommodating groove 6; one end of the first connecting rod 3.1 of the scraper 3 is movably connected with the end part of the lens frame 2, which is positioned on the bottom surface of the rearview mirror shell, and then is connected with the driving device 4, so that when the scraper 3 is accommodated in the accommodating groove 6, the hinged part of the first connecting rod 3.1 and the second connecting rod 3.2 is positioned at the intersection of the bottom surface of the rearview mirror shell and the side surface of the rearview mirror shell, which is close to the vehicle body. Furthermore, when the scraper 3 is in a straight state and works on the rear-view mirror surface, the scraper 3 swings around the circumference of the joint of the bottom and the lens frame 2, and the end part of the scraper, which is far away from the driving device 4, is adjacent to the arc-shaped edge of the lens frame 2, so that the mirror surface range in the swinging range is eliminated; meanwhile, the first spring can be controlled to keep the contraction state to control the scraper 3 to swing, and mirror surface dead angles which cannot be cleared by the scraper 3 in a straight state can be cleared.
In conjunction with the exemplary diagrams shown in fig. 3 and 4, the driving device 4 disclosed in the present application does not use an electric element such as a motor or a cylinder, which requires a waterproof structure, but uses the characteristics of the shape memory alloy to make an elastic portion to drive when the electric element is powered on. Specifically, the driving device 4 is arranged on the inner bottom surface of the rearview mirror shell and comprises a second elastic part and a swinging piece 4.3; the second elastic part comprises a second spring 4.1 and a third spring 4.2, the second spring 4.1 and the third spring 4.2 are arranged on the bottom surface of the inner side of the rearview mirror shell at intervals, and the second spring 4.1 and the third spring 4.2 are both made of shape memory alloy materials; the swinging piece 4.3 is vertically arranged between the second spring 4.1 and the third spring 4.2, the uniform end of the second spring 4.1 and the uniform end of the third spring 4.2 are connected with the bottom surface of the inner side of the rearview mirror shell, and the other end of the second spring 4.1 and the other end of the third spring are connected with the top of the swinging piece 4.3.
