Detailed implementation manners

[0034] The following further describes in detail the specific implementation manners of the present utility model by describing the optimal embodiments with reference to the accompanying drawings.

[0035] A windshield wiper device includes a wiper arm, and a wiper blade 4 is provided on the wiper arm. The windshield wiper device disclosed in the present utility model can quickly blow and clean the snow, dust and ice on the front windshield through the setting of the jet mechanism, and at the same time, cooperate with the heat exchange part to be adjusted according to different working conditions, so as to improve the cleaning efficiency of the wiper for the debris on the front windshield.

[0036] The windshield wiper device disclosed in the present utility model is mainly applicable to the front windshield or the rear windshield of a vehicle.

[0037] Specifically, the windshield wiper device disclosed in the present utility model mainly includes a wiper arm and a wiper blade 4. The wiper arm is used to connect the windshield wiper drive mechanism, that is, the windshield wiper motor. The wiper blade 4 mainly undertakes the subsequent scraping operation. During actual use, the wiper arm swings under the drive of the windshield wiper motor, and then drives the wiper blade 4 to swing reciprocally, so as to realize the actual scraping operation.

[0038] In addition, in the present utility model, a jet mechanism is provided on the wiper blade 4. The setting of the jet mechanism is mainly used to blow air on the corresponding windshield, so as to realize the corresponding impurity removal operation.

[0039] Specifically, in the present utility model, the jetting mechanism includes a nozzle 5 provided on the wiper blade 4; the nozzle 5 is connected to the wiper blade 4. The nozzle 5 can be connected to the side of the wiper blade 4, or an opening can be made on the wiper blade 4, and the nozzle 5 is embedded in the wiper blade 4. The connection method can be snap connection or bolt connection; in the present utility model, the nozzle 5 is connected to a gas supply mechanism; the gas supply mechanism is mainly used to supply gas to the nozzle 5 to facilitate subsequent gas supply operations. Specifically, in the present utility model, the gas supply mechanism includes a gas supply part, and the gas supply part can be structures such as a compressor or a blower. In order to cooperate with the vortex tube 13 for subsequent use, in the present utility model, the gas supply part can use a compressor in cooperation with a gas storage tank; at the same time, the gas supply part is connected to the nozzle 5 through a gas supply pipeline; the gas supply pipeline plays a good connection role, facilitating the separate layout of the nozzle 5 and the gas supply part and facilitating the layout and installation on the whole vehicle during production.

[0040] Furthermore, in the present utility model, the gas supply pipeline 14 is connected to the nozzle 5 through a heat exchange part; the setting of the heat exchange part in the present utility model is mainly to perform heat exchange operations on the gas in the gas supply pipeline 14, by changing the temperature of the gas supplied from the gas supply pipeline 14 to the nozzle 5; ultimately, it is applicable under appropriate working conditions.

[0041] In addition, in the present utility model, the heat exchange part includes a vortex tube 13, and the gas supply pipeline 14 is connected to the air inlet of the vortex tube 13; the hot air outlet end 15 of the vortex tube 13 is connected to the nozzle 5 through a hot air pipeline, and the cold air outlet end 16 of the vortex tube 13 is connected to the nozzle 5 through a cold air pipeline; the air compressor pressurizes and stores air in the gas storage tank. There is an electromagnetic valve on the gas storage tank, and the electromagnetic valve is connected to the air nozzle 5 through the gas supply pipeline 14. The air flow can be controlled through the electromagnetic valve. The air nozzle 5 is fixedly parallel to the wiper blade 4, and the nozzle of the nozzle 5 forms a 45-degree angle with the windshield. To achieve air heating, the gas supply pipeline 14 passes through a heating device. Here, the heater can be an electric heating wire heating device to heat the air, or the vortex tube 13 can be used to achieve heating. The high-speed air flow released from the gas storage tank generates vortices through the vortex tube 13 to separate into two cold and hot air flows. The hot end is connected to the air nozzle 5 through a hot air pipeline to achieve air heating, and the hot air blown onto the windshield can accelerate the melting of ice and snow; the cold end is connected to the nozzle 5 through a cold air pipeline to achieve air cooling, and cold air can be sprayed out in summer to accelerate the cooling of the windshield.

[0042] Meanwhile, control valves are respectively provided on the hot air pipeline and the cold air pipeline in the present utility model; generally, a three-way valve is selected for control. During actual connection, the gas storage tank is connected to the air inlet of the vortex tube 13 through a pipeline. A first three-way valve 17 is connected to the hot end air outlet of the vortex tube 13, and a second three-way valve 18 is connected to the cold end air outlet of the vortex tube 13. The first three-way valve 17 and the second three-way valve 18 are connected to the air nozzle 5 through air pipes. When hot air needs to be sprayed, the hot end air outlet is communicated with the nozzle through the first three-way valve 17, and at the same time, the cold end interface is closed and not communicated with the air nozzle 5 through the second three-way valve 18. At this time, the nozzle 5 sprays hot air. On the contrary, by adjusting the first three-way valve 17 and the second three-way valve 18, the air nozzle 5 can spray cold air. In summer, cold air can be sprayed to accelerate the cooling of the windshield, and at the same time, it can assist in blowing away the sand and stones on the windshield to prevent the glass from being scratched.

[0043] Further, in the present utility model, the scraping arm includes a first scraping arm 1 and a second scraping arm 3, and the first scraping arm 1 is rotatably connected to the second scraping arm 3; here, the rotational connection can be achieved through a rotating part, and the rotating part can be a rotating pin shaft. For example, a rotating pin shaft is provided at one end of the second scraping arm 3 close to the first scraping arm 1, and a rotating pin hole for inserting the rotating pin shaft is provided on the first scraping arm 1; such a setting enables the second scraping arm 3 to rotate relative to the first scraping arm 1; when in subsequent use, under the action of the swing adjustment mechanism, the second scraping arm 3 can rotate relative to the first scraping arm 1, and gradually approach the windshield side, realizing layer-by-layer impurity removal; in addition, a swing adjustment mechanism is provided between the first scraping arm 1 and the second scraping arm 3 in the present utility model; the swing adjustment mechanism is mainly used to enable the second scraping arm 3 to rotate relative to the first scraping arm 1, and essentially, the second scraping arm 3 can approach or move away from the corresponding windshield as needed.

[0044] There are multiple implementation manners, and the following will be explained with three embodiments.

[0045] The first embodiment:

[0046] In the present utility model, the swing adjustment mechanism includes a fixed seat 10 provided on the first scraping arm 1, and a pulling wire harness is provided on the fixed seat 10; one end of the pulling wire harness is connected to the second scraping arm 3, and the other end passes through the fixed seat 10; the pulling wire harness is connected to a pulling component for controlling the swing of the second scraping arm 3; the fixed seat 10 is fixed on the first scraping arm 1, mainly playing a role of guiding and limiting the movement of the pulling wire harness. The fixed seat 10 is provided with a through hole for the corresponding wire harness to pass through; and the pulling wire harness is connected to the second scraping arm 3. Under the action of the pulling component, the pulling wire harness drives the second scraping arm 3 to swing relative to the first scraping arm 1, thereby realizing the change of the relative interval between the second scraping arm 3 and the windshield.

[0047] Here, the pulling component can be a winch-like mechanism. By retracting or extending the upper wire harness 8 or the lower wire harness 9, the corresponding pulling operation can be achieved.

[0048] Meanwhile, in order to facilitate the rotation of the second wiper arm 3 in two directions, in the present utility model, the pulling wire harness includes an upper wire harness 8 and a lower wire harness 9; the upper wire harness 8 and the lower wire harness 9 are distributed on opposite sides of the second wiper arm 3; one end of the upper wire harness 8 and the lower wire harness 9 is connected to the second wiper arm 3 respectively, and the other end is threaded through a fixed seat 10 on the first wiper arm 1; based on such a setting, during actual use, by pulling the upper wire harness 8, the second wiper arm 3 can move towards the side away from the windshield, and by pulling the lower wire harness 9, the second wiper arm 3 can move towards the side close to the windshield. Based on such a design, it is convenient to change the position of the second wiper arm 3, and finally the purpose of gradually moving the wiper blade 4 towards the windshield can be achieved.

[0049] Second Embodiment:

[0050] In the present utility model, the swing adjustment mechanism includes a telescopic rod 12. One end of the telescopic rod 12 is hinged to the first wiper arm 1, and the other end is connected to the second wiper arm 3 through a support rod 11. The telescopic rod 12 is hinged to the support rod 11; based on such a setting, through the action of the telescopic rod 12; the telescopic movement of the telescopic rod 12 makes the side where the telescopic rod 12 is located equivalent to extending or shrinking; thus, the shape of the quadrilateral formed by the telescopic rod 12, the first wiper arm 1, the second wiper arm 3, and the support rod 11 is changed. By defining the relative arrangement position of the support rod 11 and the second wiper arm 3, the swing operation of the second wiper arm 3 can be achieved.

[0051] Based on the above design, when the telescopic rod 12 is activated, the relative position between the second wiper arm 3 and the windshield can be changed as needed, and finally the purpose of gradually moving the wiper blade 4 towards the windshield can be achieved.

[0052] Third Embodiment:

[0053] In the present utility model, the first wiper arm 1 is connected to the second wiper arm 3 through a rotating part; the rotating part includes a reduction motor 7; the reduction motor 7 can be connected to the rotating pin shaft of the rotating part; the rotating pin shaft is fixedly connected to the second wiper arm 3, and the reduction motor 7 drives the rotating pin shaft to rotate, thereby realizing the rotation operation of the second wiper arm 3.

[0054] Based on the above design, when the reduction motor 7 is activated, the relative position between the second wiper arm 3 and the windshield can be changed as needed, and finally the purpose of gradually moving the wiper blade 4 towards the windshield can be achieved.

[0055] In summary, it can be found that the swing adjustment mechanism disclosed in the present utility model has multiple implementation schemes. Therefore, theoretically, as long as the adjustment drive implementation scheme that can realize the gradual movement of the second wiper arm 3 towards the windshield is feasible.

[0056] Furthermore, in the present utility model, a tension spring 2 is provided between the first wiper arm 1 and the second wiper arm 3; the setting of the tension spring 2 has a reset function. Generally, the tension spring 2 is arranged on the side of the first wiper arm 1 and the second wiper arm 3 close to the windshield. Such a setting makes the second wiper arm 3 have a relative closing difference with the first wiper arm 1. Such a setting can provide a pre-pressure for the second wiper arm 3, so that the second wiper arm 3 presses on the windshield, facilitating subsequent use; and ensuring the friction between the wiper blade 4 and the windshield.

[0057] Furthermore, in the present utility model, an identification lamp group is provided on the wiper blade 4; the identification lamp group includes an indicator lamp 6 arranged on the wiper blade 4; the indicator lamp 6 plays a very good warning and identification role. During subsequent use, after the wiper is lifted, the lamp beads are higher than the car hood surface, which can avoid being covered by snow. When pressing the vehicle unlock key, the lamp beads flash, which can quickly find one's own vehicle on a snowy day.

[0058] A vehicle includes the above-mentioned wiper device; after parking on a snowy day, it can be sensed by a sensor or manually clicked on a button. At this time, the corresponding motor drives the wiper arm to lift, and at this time, the wiper blade 4 is separated from the windshield. When it is necessary to scrape the snow and ice on the windshield, the corresponding motor drives the wiper arm to gradually approach the windshield while making a scraping movement, scraping the snow on the windshield surface layer by layer. At the same time, the nozzle 5 blows heated air to the windshield surface to assist in removing the snow and ice on the windshield. At the same time, lamp beads are installed at the top of the wiper blade 4. After the wiper is lifted, the lamp beads are higher than the car hood surface, which can avoid being covered by snow. When pressing the vehicle unlock key, the lamp beads flash, which can quickly find one's own vehicle on a snowy day.

[0059] One can quickly find one's own vehicle in the snow, and at the same time, one can sit in the car and remove the snow and ice on the windshield with one key, improving the vehicle use experience. Specific embodiments:

[0061] The windshield wiper device pressurizes air through an air compressor and stores it in an air storage tank. An electromagnetic valve is provided on the air storage tank. The electromagnetic valve is connected to an air nozzle 5 through an air pipe. The ejection of the air flow can be controlled through the electromagnetic valve. The air nozzle 5 is fixedly arranged in parallel on the wiper blade 4. The nozzle of the nozzle 5 forms a 45-degree angle with the windshield. To achieve air heating, the air pipe passes through a heating device. Here, the heater can be an electric heating wire heating device to heat the air, or a vortex tube 13 can be used to achieve heating. The high-speed air flow released from the air storage tank generates vortices through the vortex tube 13 to separate into two cold and hot air flows. The hot end is connected to the air nozzle 5 to achieve air heating. The hot air blown onto the windshield can accelerate the melting of ice and snow. The optimized air storage tank is connected to the air inlet of the vortex tube 13. A first three-way valve 17 is connected to the hot end air outlet of the vortex tube 13, and a second three-way valve 18 is connected to the cold end air outlet of the vortex tube 13. The first three-way valve 17 and the second three-way valve 18 are connected to the air nozzle 5 through an air pipe. When hot air needs to be ejected, the hot end air outlet is communicated with the nozzle through the first three-way valve 17, and at the same time, the cold end interface is closed and not communicated with the air nozzle 5 through the second three-way valve 18. At this time, the nozzle 5 ejects hot air. On the contrary, by adjusting the first three-way valve 17 and the second three-way valve 18, the air nozzle 5 can eject cold air. In summer, cold air can be ejected to accelerate the cooling of the windshield, and at the same time, it can assist in blowing away the sand and gravel on the windshield to prevent the glass from being scratched.

[0062] To achieve the automatic lifting of the wiper arm, there are the following three solutions;

[0063] Solution 1: One end of the second wiper arm 3 is rotatably connected to the first wiper arm 1. The other end of the second wiper arm 3 is connected with a wiper blade 4. An upper wire harness 8 is fixed above the second wiper arm 3, and a lower wire harness 9 is fixed below the second wiper arm 3. The outer sleeve of the wire harness is fixed on the fixed seat 10 of the first wiper arm 1. By pulling the upper wire harness 8 and releasing the lower wire harness 9, the lifting of the second wiper arm 3 can be controlled, and the wiper blade 4 leaves the windshield. On the contrary, the lowering of the second wiper arm 3 can be controlled to make the wiper blade 4 closely adhere to the windshield. The air nozzle 5 is fixedly arranged in parallel on the wiper blade 4. An indicator light 6 is arranged at the end of the wiper blade 4. The indicator light 6 is a three-color LED lamp and is connected to the controller through a circuit. When the vehicle unlock button is pressed, the controller controls the three-color LED lamp to flash to play a prompting role.

[0064] The wire harness here can adopt a wire harness structure similar to that of a brake wire.

[0065] Solution 2: One end of the second wiper arm 3 is rotatably connected to the first wiper arm 1, and a wiper blade 4 is connected to the other end of the second wiper arm 3. A support rod 11 is provided on the second wiper arm 3. One end of the electric telescopic rod 12 is rotatably connected to the first wiper arm 1, and the other end is rotatably connected to the second wiper arm 3. The lifting and lowering of the second wiper arm 3 can be controlled by the electric telescopic rod 12. Optimally, a tension spring 2 is arranged between the second wiper arm 3 and the first wiper arm 1. After the wiper blade 4 is in close contact with the windshield, the tension of the tension spring 2 keeps the wiper blade 4 in close contact with the windshield, ensuring the scraping effect.

[0066] Solution 3: A reduction motor 7 is arranged between the second wiper arm 3 and the first wiper arm 1, and a wiper blade 4 is connected to the other end of the second wiper arm 3. The lifting and lowering of the second wiper arm 3 can be controlled by the rotation of the reduction motor 7. Optimally, a tension spring 2 is arranged between the second wiper arm 3 and the first wiper arm 1. After the wiper blade 4 is in close contact with the windshield, the reduction motor 7 stops working, and the tension of the tension spring 2 keeps the wiper blade 4 in close contact with the windshield, ensuring the scraping effect.

[0067] During overall implementation:

[0068] Lift the wiper arm after parking. When it is necessary to scrape the snow and ice on the windshield, the motor drives the wiper arm to gradually approach the windshield while making a scraping movement, scraping the snow on the windshield surface layer by layer. At the same time, the air tank in the vehicle blows the heated air to the windshield surface through the air pipe to assist in removing the snow and ice on the windshield. At the same time, a lamp bead is installed at the top of the wiper blade 4. After the wiper is lifted, the lamp bead is higher than the car hood surface, which can avoid being covered by snow. When the vehicle unlock button is pressed, the lamp bead flashes, which can quickly find your own vehicle on a snowy day.

[0069] Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
