Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and specifically provides a windshield wiper for a vehicle and a vehicle. Background Art

[0002] With the development of society, cars have become an essential means of transportation in people's daily lives. In common traffic accidents, when a car collides with a pedestrian outside the car, the car's front windshield wiper shaft often causes harm to the pedestrian during the collision.

[0003] Traditional wipers usually have a fracture inducing structure between the bushing seat sleeve and the body mounting part. When the car collides with a pedestrian outside the car, the material failure is used to break the wiper shaft, so that the wiper shaft is disconnected from the body mounting part to reduce the damage to the pedestrian. The traditional solution has the following defects: 1. It relies too much on the stability of the material, which may cause the wiper shaft to break under bumpy road conditions or fail to break after a pedestrian collision; 2. Due to the error of a single component, the research and development cycle of the fracture inducing structure is long and the cost is high in the actual manufacturing process; 3. The method of using fracture force failure to reduce pedestrian damage has limitations. Before the fracture inducing structure breaks, the wiper shaft will still generate a large reaction force on the pedestrian, and the degree of reduction in pedestrian damage is limited; 4. After the fracture inducing structure breaks, the wiper will fail and the entire wiper needs to be replaced, resulting in high maintenance costs.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0035] First refer to Figure 1 and Figure 2 , the windshield wiper of the vehicle of the utility model is described. Among them, Figure 1 It is a structural diagram of the wiper of the utility model; Figure 2 It is a structural diagram of the bushing seat of the utility model.

[0036] In order to solve the problem that the wiper shaft is easy to cause harm to pedestrians and the maintenance cost is high in the event of a collision, the wiper of the vehicle of the utility model includes at least one group of wiper mechanisms; wherein the wiper mechanism includes a wiper shaft 5 and a bushing seat 1, the bushing seat 1 includes a sleeve 13 and a mounting arm, the wiper shaft 5 is rotatably arranged in the sleeve 13, the mounting arm includes a first mounting arm 11 and a second mounting arm 12, the first mounting arm 11 is arranged on the sleeve 13 and is arranged on the vehicle body through the sleeve 13, and the second mounting arm 12 is arranged on the vehicle body; a magnetic attraction component 2 is provided between the first mounting arm 11 and the second mounting arm 12, and the two are connected or disconnected through the magnetic attraction component 2.

[0037] The utility model sets a magnetic component 2 between the first mounting arm 11 and the second mounting arm 12, and connects or disconnects the first mounting arm 11 and the second mounting arm 12 through the attraction or repulsion of the magnetic component 2, so that the wiper shaft 5 can be disconnected from the second mounting arm 12. Through the above arrangement, when a pedestrian hits the wiper shaft 5, the wiper shaft 5 can be deflected and moved with the connection between the first mounting arm 11 and the vehicle body as a fulcrum, ensuring the safety of the pedestrian and avoiding the damage caused by the inability of the wiper shaft 5 to be disconnected from the second mounting arm 12. In addition, the mounting arm is set in the form of the first mounting arm 11 and the second mounting arm 12 connected by the magnetic component 2, so that after the magnetic component 2 is disconnected, the overall structure of the wiper is not affected, avoiding damage to the wiper; it also cleverly utilizes the characteristics of the magnetic component 2, simplifies the installation and disassembly process of the wiper shaft 5, reduces the maintenance cost, and further enhances the practicality and safety of the wiper.

[0038] See below for further reference Figure 1 and Figure 2 , a preferred embodiment of the wiper of the utility model is introduced. Those skilled in the art will understand that the embodiments described below are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. On the premise that the wiper includes at least one set of wiper mechanisms, and the wiper mechanism includes at least a wiper shaft 5 and a bushing seat 1, those skilled in the art can adjust the following settings so that the present application can be applied to more specific application scenarios.

[0039] See also Figure 1 The wiper of the utility model comprises a wiper mechanism, a driving mechanism 4 and a crank 6, wherein the driving mechanism 4 is arranged on the vehicle body (not shown in the figure), the number of the wiper mechanisms is 2, and the two wiper mechanisms are respectively arranged on opposite sides of the driving mechanism 4 (such as Figure 2 The first end of the crank 6 is arranged at the output end of the driving mechanism 4, so that the driving mechanism 4 can drive the crank 6 to rotate. Each wiper mechanism includes a wiper shaft 5, a bushing seat 1 and a transmission assembly 3. The bushing seat 1 is arranged on the vehicle body, the wiper shaft 5 is rotatably arranged on the bushing seat 1, the first end of the transmission assembly 3 is connected to the wiper shaft 5, and the second end thereof is rotatably connected to the second end of the crank 6; when the driving mechanism 4 drives the crank 6 to rotate, the crank 6 can drive the transmission assembly 3 to move, thereby driving the wiper shaft 5 to rotate.

[0040] Of course, the utility model is not necessarily provided with the crank 6 and the transmission assembly 3, and those skilled in the art can select them according to the needs. When the crank 6 and the transmission assembly 3 are not provided, two driving mechanisms 4 can be provided, and the two wiper shafts 5 are respectively provided at the output ends of the two driving mechanisms 4, and the two driving mechanisms 4 each drive one wiper shaft 5 to rotate.

[0041] like Figure 1 and Figure 2 As shown, the bushing seat 1 includes a first mounting arm 11 and a second mounting arm 12. One end of the first mounting arm 11 is arranged on the driving mechanism 4, and the other end is provided with a first magnetic member 2. The second mounting arm 12 has a first mounting position 121, and the first mounting position 121 can be connected to the vehicle body, so that the second mounting arm 12 is arranged on the vehicle body; the wiper shaft 5 is rotatably arranged on the first mounting arm 11. The first mounting arm 11 is provided with a first magnetic member 2, and the second mounting arm 12 is provided with a second magnetic member 3. The first magnetic member 2 and the second magnetic member 3 are both electromagnets. By changing the current direction of the first magnetic member 2 and the second magnetic member 3, the magnetic poles of the first magnetic member 2 and the second magnetic member 3 can be changed, thereby changing the state of attraction or repulsion between the first magnetic member 2 and the second magnetic member 3, so that the first mounting arm 11 and the second mounting arm 12 are connected or disconnected, so that the wiper shaft 5 can be disconnected from the second mounting arm 12.

[0042] Specifically, when there is a risk of pedestrian collision, the current directions in the first magnetic member 2 and the second magnetic member 3 on both sides are controlled respectively so that the first magnetic member 2 and the second magnetic member 3 repel each other, and the first mounting arms 11 on both sides can be disconnected from the second mounting arms 12, so that the wiper shafts 5 on both sides can be disconnected from the second mounting arms 12. Through the above arrangement, when a pedestrian hits the wiper shaft 5, the two wiper shafts 5 can be deflected and moved with the connection between the first mounting arm 11 and the vehicle body as a fulcrum, which not only ensures the safety of the pedestrians, but also avoids the damage caused by the inability of the wiper shaft 5 to be disconnected from the connection with the second mounting arm 12. In addition, after the risk is eliminated, the current directions in the first magnetic member 2 and the second magnetic member 3 on both sides are controlled respectively so that the first magnetic member 2 and the second magnetic member 3 attract each other, and the first mounting arms 11 on both sides can be reconnected with the second mounting arms 12, so that the wiper returns to normal. Through the above arrangement, the wiper can restore to a normal state through the magnetic properties of the first magnetic component 2 and the second magnetic component 3 without replacing other parts, thereby reducing maintenance costs and further enhancing the practicality and safety of the wiper.

[0043] It should be noted that the utility model does not limit the types of the first magnetic component 2 and the second magnetic component 3, and those skilled in the art can flexibly adjust and set them according to actual needs. For example, the first magnetic component 2 is an electromagnet and the second magnetic component 3 is a permanent magnet. At this time, by changing the current direction of the first magnetic component 2, the magnetic pole of the first magnetic component 2 can be changed, thereby changing the state of attraction or repulsion between the first magnetic component 2 and the second magnetic component 3, so that the first mounting arm 11 and the second mounting arm 12 are connected or disconnected. For another example, the first magnetic component 2 is a permanent magnet and the second magnetic component 3 is an electromagnet. At this time, by changing the current direction of the second magnetic component 3, the magnetic pole of the second magnetic component 3 can be changed, thereby changing the state of attraction or repulsion between the first magnetic component 2 and the second magnetic component 3, so that the first mounting arm 11 and the second mounting arm 12 are connected or disconnected.

[0044] It should also be noted that the present invention does not limit the shapes of the first magnetic member 2 and the second magnetic member 3, and those skilled in the art can flexibly adjust and set them according to actual needs. For example, the first magnetic member 2 is a square magnet, a cylindrical magnet, or a circular magnet, etc.; and / or, the second magnetic member 3 is a square magnet, a cylindrical magnet, or a circular magnet, etc.

[0045] Continue to refer to Figure 1 and Figure 2 A sleeve 13 is provided on the first mounting arm 11 , a portion of the wiper shaft 5 is disposed in the sleeve 13 , and the other portion extends out of the sleeve 13 and is connected to the first end of the transmission assembly 3 , so that the transmission assembly 3 can drive the wiper shaft 5 to rotate in the sleeve 13 .

[0046] like Figure 1 As shown, the transmission assembly 3 includes a first connecting rod 31 and a second connecting rod 32. The first end of the first connecting rod 31 is connected to the wiper shaft 5, the first end of the second connecting rod 32 is rotatably connected to the crank 6, and the second end of the first connecting rod 31 is rotatably connected to the second end of the second connecting rod 32. At this time, the crank 6 can form a crank-connecting rod mechanism together with the second connecting rod 32 and the first connecting rod 31. Under the action of the driving mechanism 4, the crank 6 can rotate around the output end of the driving mechanism 4 and drive the second connecting rod 32 and the first connecting rod 31 to move, thereby driving the wiper shaft 5 to rotate.

[0047] like Figure 1 As shown, the driving mechanism 4 includes a motor bracket 42 and a driving motor 41 arranged on the motor bracket 42. The motor bracket 42 has a second mounting position 421 and is arranged on the vehicle body through the second mounting position 421; the first end of the crank 6 is arranged at the output end of the driving motor 41, and the driving motor 41 can drive the crank 6 to rotate.

[0048] like Figure 1As shown, the wiper also includes a support rod 7, the middle part of the support rod 7 is arranged on the motor bracket 42, and the two ends of the support rod 7 are respectively arranged on the two first mounting arms 11, so that the two wiper mechanisms and the driving mechanism 4 are integrated into a whole, and the two first mounting arms 11 can be arranged on the vehicle body through the support rod 7. When the wiper is assembled on the vehicle body, the wiper can be taken and placed as a whole by just taking the support rod 7, which is convenient for the assembly of the wiper and has the advantage of improving the stability of the wiper.

[0049] It should be noted that the connection form between the support rod 7 and the first mounting arm 11 is not fixed in the present invention, and those skilled in the art can flexibly adjust it according to the actual product situation. For example, the support rod 7 is a tubular structure, and the sleeve 13 of the first mounting arm 11 is provided with a connecting piece 14, and the connecting piece 14 is inserted into the support rod 7, so that the support rod 7 is set on the first mounting arm 11; for another example, the support rod 7 is set on the first mounting arm 11 by welding.

[0050] In addition, it should be noted that the number of support rods 7 provided in the present invention is not fixed, and those skilled in the art can flexibly adjust it according to the actual product conditions. For example, two support rods can be provided, and the first ends of the two support rods are both provided on the motor bracket 42, and the second ends are respectively provided on the two first mounting arms 11.

[0051] It is worth mentioning that the wiper also includes a wiper arm (not shown in the figure), one end of which is arranged on the wiper shaft 5 and is in contact with the windshield. When the drive motor 41 drives the wiper shaft 5 to rotate, the wiper arm can rotate with the wiper shaft 5 as a fulcrum, so that the wiper arm can remove water on the windshield.

[0052] It should be noted that the number of wiper mechanisms provided in the present invention is not fixed, and those skilled in the art can flexibly adjust it according to needs. For example, one set of wiper mechanisms can also be provided, and in this case, the wiper includes the set of wiper mechanisms, the drive mechanism 4 and the crank 6, wherein the wiper mechanism, the drive mechanism 4 and the crank 6 have all the technical effects of the above preferred embodiments, which will not be repeated here.

[0053] The working process of the wiper of the utility model when a collision occurs is described below.

[0054] During the driving process of the vehicle, when it is detected that the distance between a pedestrian and the vehicle is too close, there may be a risk of pedestrian collision. In this case, the direction of the current in the first magnetic component 2 and the second magnetic component 3 is controlled to disconnect the first mounting arm 11 from the second mounting arm 12, thereby disconnecting the wiper shaft 5 from the second mounting arm 12. After the risk is eliminated, the direction of the current in the first magnetic component 2 and the second magnetic component 3 is controlled to connect the first mounting arm 11 to the second mounting arm 12, thereby restoring the wiper to a normal state. Specifically, if no pedestrian collision occurs, the direction of the current in the first magnetic component 2 and the second magnetic component 3 is controlled to connect the first mounting arm 11 to the second mounting arm 12, thereby restoring the wiper to a normal state; if a collision has occurred, the user is required to manually power on and control the direction of the current in the first magnetic component 2 and the second magnetic component 3 to connect the first mounting arm 11 to the second mounting arm 12, thereby restoring the wiper to a normal state.

[0055] In addition, the utility model also provides a vehicle, which includes a wiper of any of the above-mentioned embodiments and has all the technical effects of the above-mentioned embodiments, which will not be repeated here.

[0056] Finally, it is worth mentioning that the windshield wiper technology adopted by the utility model can be applied not only to cars, but also to off-road vehicles, trucks or vans, etc. This adjustment of the application object does not deviate from the principle and scope of the utility model. Among them, the vehicle can be an electric car, a hybrid car, a gasoline car and other vehicles, which are not listed here one by one.

[0057] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
