The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A wiper blade 100 according to an embodiment of the present invention will be described in detail with reference to fig. 1.

As shown in fig. 1, a wiper blade 100 according to an embodiment of the present invention may generally include: at least one wiper assembly 10, a drive mechanism 20 and an intermediate transmission member 30.

Specifically, as shown in fig. 1, the wiper assembly 10 has a rotary shaft 11 and a wiper blade 12 coupled to one end of the rotary shaft 11, the other end of the rotary shaft 11 is provided with a driving gear 13, a driving mechanism 20 includes a driving motor 21 and a driving gear 22 coupled to a driving shaft of the driving motor 21, and an intermediate transmission member 30 is adapted to be engaged with the driving gear 13 and the driving gear 22.

The wiper assembly 10 includes at least one, for example, the wiper assembly 10 includes one, and correspondingly, a transmission gear 13 is connected to the other end of the rotating shaft 11 of the wiper assembly 10. The wiper assembly 10 may further include two wiper assemblies, and a transmission gear 13 is correspondingly connected to the other end of the rotary shaft 11 of each wiper assembly 10. Of course, the wiper assembly 10 may also include three or more, the number of which is not exhaustive and applicant does not enumerate one by one.

In the above structure, the driving mechanism 20 drives the intermediate transmission member 30 engaged with the driving mechanism 20 to operate, and the intermediate transmission member 30 moves to drive the wiper assembly 10 engaged with the intermediate transmission member 30 to operate, so that the wiper blade 12 can play a role of wiping rain, and the rain on the windshield can be cleaned in time to avoid blocking the sight of the driver.

Specifically, when the driving motor 21 operates, the driving shaft rotates to drive the driving gear 22 connected to the driving shaft to rotate, because the intermediate transmission member 30 is meshed with the driving gear and connected, under the driving of the driving gear 22, the intermediate transmission member 30 rotates, because the intermediate transmission member 30 is meshed with the transmission gear 13 and connected, under the driving of the intermediate transmission member 30, the transmission gear 13 rotates, the transmission gear 13 is fixedly connected with the other end of the rotating shaft 11 of the wiper assembly 10, the rotating shaft 11 rotates under the driving of the transmission gear 13 to drive the wiper blade 12 connected to one end of the rotating shaft 11 to rotate, and therefore the wiper 100 can play a role in wiping rain, and clear sight of a driver is ensured.

It can be understood that the gear transmission has the advantage of stable transmission ratio, the moving speed of the wiper blade 12 is only related to the running speed of the driving motor 21 and has positive correlation, there are no singularities and transient speeds, the abnormal noise generated by the transmission mechanism due to the speed jump is reduced, and the abnormal noise generated by the suddenly accelerated friction between the wiper blade 12 and the windshield during the speed jump is reduced. Because the wiper 100 of the present application has the characteristic of stable transmission, that is, the running speed of the wiper 100 is uniform, the abrasion between the wiper blade 12 and the windshield can be reduced, and the service lives of the wiper blade 12 and the windshield are prolonged.

Therefore, according to the utility model discloses wiper 100 through using intermediate transfer spare 30 to mesh drive gear 13 and driving gear 22 respectively and connect, can guarantee that wiper 100's operation is stable, reduces the abnormal sound and improves wiper blade 12 and windshield's life.

Due to the advantage of stable transmission ratio of gear transmission, the driving motor 21 can be combined with the arrangement size and the reasonable matching speed of the wiper blade 12 to ensure that the wiper blade 12 runs at a constant speed when being wiped and reduce abnormal sound generated between the wiper blade 12 and the windshield and friction between the wiper blade 12 and the windshield when being wiped. Wherein the rotational speed of the wiper blade 12 is based on the realization that rain on the windshield will not affect the driver during rain.

In order to achieve the above object, since the rainfall amount is different in rainy days, the rotation speed of the driving motor 21 may be adjusted according to the rainfall amount. When the amount of rainfall is large, the rotation speed of the drive motor 21 is high, and when the amount of rainfall is small, the rotation speed of the drive motor 21 is low, in other words, the rotation speed of the drive motor 21 when the amount of rainfall is large is larger than the rotation speed of the drive motor 21 when the amount of rainfall is small, and the rotation speed of the drive motor 21 is positively correlated with the amount of rainfall. Therefore, the rainwater on the windshield can not influence the realization of a driver, and the energy is saved.

In some embodiments, the intermediate drive 30 is at least one of a belt, a chain, a gear, a worm gear, and a worm. For example, the intermediate transmission member 30 is a belt, and the inner side of the belt is provided with teeth suitable for being meshed with the driving gear 22 and the transmission gear 13; or, the intermediate transmission member 30 is a chain, a plurality of slots are arranged on the chain at intervals, and the teeth of the driving gear 22 and the transmission gear 13 are suitable for being inserted into the slots of the chain; alternatively, the intermediate transmission member 30 is a gear adapted to be engaged with the driving gear 22 and the transmission gear 13; or, the intermediate transmission member 30 is a worm wheel or a worm screw, the worm wheel or the worm screw has the advantages of stable transmission, large transmission ratio and low noise, and the worm wheel or the worm screw is respectively meshed with the driving gear 22 and the transmission gear 13.

Of course, the intermediate transmission member 30 according to the embodiment of the present invention is not limited to the above-mentioned cases, as long as the intermediate transmission member 30, the transmission gear 13 and the driving gear 22 are engaged with each other.

In one embodiment, as shown in fig. 1, the wiper assembly 10 includes two sets of spaced apart drive gears 22, the intermediate transmission member 30 is a belt, and the inner race of the belt is provided with teeth adapted to engage with the drive gears 22 and the transmission gear 13. Through setting up windscreen wiper subassembly 10 to setting up to two sets of in actuating mechanism 20 both sides, windscreen wiper blade 12 scrapes the rainwater of brushing the windshield that is located actuating mechanism 20 both sides respectively, can scrape the windshield of brushing a large area simultaneously, guarantees that the rainwater on the windshield can in time effectually be clear away, also is favorable to reducing the size of windscreen wiper blade 12, avoids the too big and influence driver's sight of size of windscreen wiper blade 12. Wherein, through setting up intermediate transfer member 30 to the belt, because the belt is stable sharp drive, compare in many connecting rods transmission structure, do not need too big layout space, also set up intermediate transfer member 30 to the belt, its occupation space is certain, need not additionally set up and dodge the space and keep away the position in order to keep away the movement track of intermediate transfer member 30 in the operation process, reduced the occupation space of wiper 100, can leave more design space on the vehicle.

In some embodiments, as shown in FIG. 1, the drive gear 22 and the two transfer gears 13 are triangularly disposed. In other words, the axes of the driving gear 22 and the two transmission gears 13 are not on the same straight line, so that the belt tensioning device can play a role in tensioning the belt, and can effectively avoid the situation that the belt slips or even falls off from the driving gear 22 and the transmission gears 13. Specifically, the driving gear 22 is located between the two transmission gears 13, wherein the axis of the driving gear 22 is located above the line connecting the axes of the two transmission gears 13, and the condition that the tooth diameter of the driving gear 22 is larger than the tooth diameter of the transmission gear 13 is small, and the lower side of the driving gear 22 is spaced from the inner side surface of the belt to avoid interference.

Of course, under the condition that the driving gear 22 and the two transmission gears 13 are distributed in a triangular shape, one or more tension pulleys can be arranged to further tension the belt, so that the stable operation of the belt can be further ensured. The number of the tensioning wheels can be one, two, three or more, and the arrangement positions of the tensioning wheels are arranged according to the tight edges and the loose edges, which is not described in detail by the applicant.

In some embodiments, as shown in fig. 1, a telescopic connecting rod 40 is provided between the two rotating shafts 11. Through setting up flexible connecting rod 40, can adjust the rate of tension of belt through adjusting the interval between two rotation axes 11 to guarantee the operating stability of belt, still made things convenient for the assembly of belt. For example, at the initial interval, the belt is loosely assembled with the transmission gear 13 and the driving gear 22, and after the preassembly is completed, the telescopic connecting rod 40 is extended to increase the interval between the two rotating shafts 11, so that the belt can be tensioned, and the problems of belt breakage, tooth abrasion of the transmission gear 13 and the driving gear 22 and the like caused by violent assembly are avoided. After the assembly is completed, if the belt is loosely assembled due to abrasion after long-time operation, the belt can be tensioned by further extending the telescopic connecting rod 40, and the distance between the two rotating shafts 11 can be reduced by contracting the telescopic connecting rod 40, so that the belt can be conveniently disassembled, and some problems caused by violent disassembly can be avoided.

In the above-mentioned embodiment, the implementation of the telescopic connecting rod 40 is various, and it is not specifically limited here, for example, the telescopic connecting rod 40 can be realized by a slider-crank mechanism, and can also be realized by a hydraulic rod, no matter which implementation is specific, the scheme of adjusting the interval between two transmission gears 13 by the telescopic mode should fall into the protection scope of the present invention.

The mounting lug 50 is used for connecting with a vehicle body of a vehicle, the rotating shaft 11 can be relatively fixedly mounted on the vehicle by the mounting lug 50, and the rotating shaft 11 is prevented from being displaced relative to the vehicle, wherein the rotating shaft 11 passes through a connecting hole on the mounting lug 50, and a gap is formed between the rotating shaft 11 and the connecting hole, so that the rotating shaft 11 cannot be greatly interfered with the mounting lug 50 when rotating, and the rotating of the rotating shaft 11 is not influenced. That is, the mounting lugs 50 can fix the rotating shaft 11 on the one hand and can reduce the influence of the mounting lugs 50 on the rotation of the rotating shaft 11 on the other hand.

Of course, it can be understood that, during a long period of rotation, since friction inevitably occurs between the rotary shaft 11 and the coupling hole, when the abrasion is large, the fixation and rotation of the rotary shaft 11 are affected. In order to reduce the influence of friction, it is preferable to provide a bearing between the rotary shaft 11 and the mounting lug 50, by which the above-mentioned problems due to friction can be effectively avoided. Of course, the bearing is not the only option, and a liquid or powder such as a lubricating oil for reducing friction may be provided between the rotary shaft 11 and the mounting lug 50.

Thus, when the sizes of the vehicle models are different, the wiper 100 can adapt to the vehicle models with different sizes by changing the fixed position of the installation lug 50 and by the telescopic adjustment of the telescopic connecting rod 40, and the universality is high.

In some embodiments, as shown in FIG. 1, the diameter of one end of the rotating shaft 11 is smaller than the diameter of the other end of the rotating shaft 11. Thus, the wiper blade 12 can be advantageously miniaturized, and the material loss of the rotary shaft 11 can be reduced.

As shown in fig. 1, a mounting structure 60 is further included, and the driving mechanism 20 is locked to the mounting structure 60. By providing the mounting structure 60, the mounting structure 60 is fixedly connected to the vehicle body, and the driving mechanism 20 is locked to the mounting structure 60, the driving structure can be relatively fixedly disposed in the vehicle, so that the whole system of the wiper 100 is stable.

The driving mechanism 20 may be wrapped in the mounting structure 60, the driving mechanism 20 may be welded to the mounting structure 60, the driving mechanism 20 may be screwed to the mounting structure 60, or the driving mechanism 20 may be snapped, joggled, or riveted to the mounting structure 60.
