Abstract
The utility model provides a simple structure is light, two wipers of single motor subtend that work efficiency is high. Its structure includes first windscreen wiper arm assembly and second windscreen wiper arm assembly, and the fulcrum of first windscreen wiper arm assembly and second windscreen wiper arm assembly is connected through reverse drive mechanism, and the opposite side of the fulcrum of first windscreen wiper arm assembly passes through the transmission shaft and links to each other with the motor, is equipped with the stopper that is used for preventing first windscreen wiper arm and the coincidence of second windscreen wiper arm on the movement track coincidence line of first windscreen wiper arm assembly and second windscreen wiper arm assembly. The utility model discloses because the fulcrum that has adopted simple reverse drive mechanism to connect two windscreen wiper assemblies adopts single motor to drive, compare with prior art, work efficiency is high, and has reduced a great part and connected the metal pole, and the total is simpler light, can effectively avoid and reduce the linkage fault that probably appears.
Description
Technical field
The utility model relates to wiper technical field, is specifically related to the two wiper of a kind of single motor subtend.
Background technology
Current existing windscreen wiper system is all need left and right wiper arm arranged apart.Wiper arm bindiny mechanism will be caused so comparatively complicated, and connecting bridge Metallic rod part, also can have a certain impact to tare.And windscreen wiper has wiper lap in the same way, some is idle work to cause wiping effect.
Summary of the invention
The purpose of this utility model is that proposition is a kind of simple and light, the two wiper of single motor subtend that work efficiency is high.
According to the two wiper of single motor subtend that the utility model provides, comprise the first wiper arm assembly and the second wiper arm assembly, described first wiper arm assembly is connected by reverse transmission device with the fulcrum of the second wiper arm assembly, the opposite side of the fulcrum of described first wiper arm assembly is connected with motor by transmission shaft, and the path of motion coincidence line of described first wiper arm assembly and the second wiper arm assembly is provided with the limiting device for preventing the first wiper arm and the second wiper arm from overlapping.
The two wiper of single motor subtend of the present utility model, the fulcrum of two windscreen wiper assembly is connected owing to have employed simple reverse transmission device, single motor is adopted to drive, compared with prior art, work efficiency is high, and decreasing considerable part connection metal bar, total is more simply light, effectively can avoid and reduce the connection fault that may occur.
As preferred embodiment, described reverse transmission device comprises the Connection Block of hollow connection pipe, reverse gear and bearing shape, the fulcrum of described first wiper arm assembly is connected on the tube wall of described hollow connection pipe one end, described reverse gear is arranged on the tube wall of the other end of hollow connection pipe, described Connection Block is connected with described hollow connection pipe by reverse gear, described transmission shaft drives with hollow connection pipe and is connected, and the fulcrum of described second wiper arm assembly is connected on described Connection Block.The counter motion of the first wiper arm assembly fulcrum and the second wiper arm assembly fulcrum can be realized by reverse gear, realize the subtend scraping work of two windscreen wiper.
Further, described limiting device is the limiting section being separately positioned on described Connection Block perisporium and described hollow connection tube wall, the limiting section of described Connection Block perisporium and described hollow connection tube wall vertically relative extend spacing.Spacing mutually by the limiting section more near pivot point, the moment produced when can reduce spacing, reduces the impact damage to wiper arm assembly.
Further, described limiting device is elastic material, clashes into the energy of limiting section with wiper arm assembly during buffer limit, reduces the impact damage to wiper arm assembly further.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the axial sectional structure schematic diagram of Fig. 1.
Fig. 3 is principle of work schematic diagram of the present utility model.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As Fig. 1,2,3, the two wiper of this single motor subtend, comprise the first wiper arm assembly 1 and the second wiper arm assembly 2, the fulcrum 11 of the first wiper arm assembly 1 is connected by reverse transmission device with the fulcrum 21 of the second wiper arm assembly 2, the opposite side of the fulcrum 11 of the first wiper arm assembly 1 is connected with motor by transmission shaft 3, and the path of motion coincidence line of the first wiper arm assembly 1 and the second wiper arm assembly 2 is provided with the limiting device 4 for preventing the first wiper arm and the second wiper arm from overlapping.As preferred embodiment, reverse transmission device comprises the Connection Block 7 of hollow connection pipe 5, reverse gear 6 and bearing shape, the fulcrum 11 of the first wiper arm assembly is connected on the tube wall of hollow connection pipe 5 one end, reverse gear 6 is arranged on the tube wall of the other end of hollow connection pipe 5, Connection Block 7 is connected with hollow connection pipe 5 by reverse gear 6, transmission shaft 3 drives with hollow connection pipe 5 and is connected, and the fulcrum 21 of the second wiper arm assembly is connected on Connection Block 7.The counter motion of the first wiper arm assembly fulcrum 1 and the second wiper arm assembly fulcrum 2 can be realized by reverse gear 6, realize the subtend scraping work of two windscreen wiper.The limiting section 51 that limiting device 4 is the limiting section 71 and hollow connection pipe 5 tube wall that are separately positioned on Connection Block 7 perisporium, the limiting section 71 of Connection Block 7 perisporium is spacing with the limiting section 51 relative extension vertically of hollow connection pipe 5 tube wall.By more near the limiting section 71 of pivot point and limiting section 51 spacing mutually, the moment produced when can reduce spacing, reduces the impact damage to wiper arm assembly.Limiting device 4 namely limiting section 71 and limiting section 51 is elastic material.
