Description

Vehicle assembly and automobile

Technical Field

The application relates to the technical field of automobiles, in particular to a vehicle component and an automobile.

Background

In the prior art, two main spraying modes of automobile glass water are adopted, one is sprayed through a water spraying port arranged on a front cabin cover, and the other is sprayed from a nozzle arranged on a wiper blade of a water spraying type windscreen wiper.

The technical principle of the water-spraying type windscreen wiper is as follows: the common wiper blade arranged on the wiper arm is provided with a nozzle which is connected with a water pipe hidden in the wiper arm, and glass water is conveyed to the wiper blade through the water pipe and is sprayed out through the nozzle on the wiper blade. When the water spraying type windscreen wiper works, the water spraying position can synchronously move along with the windscreen wiper blade. Compared with the traditional mode of arranging the water spraying port on the front hatch cover, the water spraying type windscreen wiper can save half of glass water quantity, and can enable a driver to obtain a clearer view.

However, when the water spraying type windscreen wiper is adopted, the water pipe extends out of the windscreen wiper arm and is connected with the water pipe on the ventilation cover plate. Because of the swinging requirement of the wiper arm, the water pipe must leave enough allowance for the rotation of the wiper arm, which leads to redundancy of the water pipe outside the vent flap, and influences the appearance of the vehicle.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings.

In order to facilitate understanding of the vehicle component and the automobile provided by the embodiment of the application, first, an application scenario thereof is described. The vehicle component provided by the embodiment of the application is used for a vehicle, and is particularly used for being matched with a water spraying type windscreen wiper to clean a front windshield. The existing water pipe part which is matched with the water spraying type windscreen wiper and used for conveying the glass cleaning agent is exposed out of the ventilation cover plate so as to leave enough allowance for swinging of the windscreen wiper arm. When the wiper arm is reset, the allowance is bent and exposed above the vent flap, and the appearance of the vehicle is affected. To this end, the present application provides a vehicle assembly for improving the vehicle appearance. The following description is made with reference to the accompanying drawings and specific embodiments thereof.

For the convenience of understanding the movement of the water jet wiper tube, two states of the wiper arm swinging are defined. When the water spraying type windscreen wiper does not work, the windscreen wiper arm stays at the edge below the front windscreen, and the state is called an initial state (also called a reset state); when the water spraying type windscreen wiper works, the windscreen wiper arm can swing back and forth around the rotating shaft, and the state when the windscreen wiper arm swings to the maximum angle is called the farthest state. One duty cycle of the water jet wiper is: the swing is started to the farthest state in the initial state, and then the swing is returned to the initial state.

In addition, upper and lower vent flaps are defined: the upper part of the ventilation cover plate refers to the area of the ventilation cover plate facing one side of the wiper arm; the lower part of the vent flap refers to the area of one side of the vent flap, which is away from the wiper arm.

Referring to fig. 1, fig. 1 is a schematic diagram of a vehicle component according to an embodiment of the present application. The vehicle assembly provided by the embodiment of the application comprises a water-spraying type wiper tube 10 and a vent cover plate 20. The vent flap 20 is provided with a through hole 21 for penetrating the water jet wiper tube 10. The water-jet wiper tube 10 is inserted into the through hole 21 and is slidable in the through hole 21 when assembled. One end of the water spraying type wiper tube 10 extending to the outer side of the ventilation cover plate 20 can be connected with the wiper arm 30; the opposite end is located below vent flap 20 and extends to and connects with the tank storing the glass cleaning solution.

Referring to fig. 1 and fig. 2 together, fig. 2 is an expanded schematic view of a redundant segment of a water jet wiper tube according to an embodiment of the present application. The water-jet wiper tube 10 has a redundant section 11, the redundant section 11 being located below the vent flap 20. The redundant segment 11 is used to provide the margin required for the swinging movement of the wiper arm 30. When the wiper arm 30 is in the initial state, the redundant segment 11 is curved below the vent flap 20, such as the state shown in fig. 1; in the process that the wiper arm 30 swings to the farthest state, the wiper arm 30 pulls a part of the water spraying type wiper tube 10 to penetrate out of the through hole 21, the redundant section 11 is stretched, and the bending curvature of the redundant section 11 is reduced or is in a straight line; when the wiper arm 30 swings to the farthest state, the redundant segment 11 assumes an extended state such as in fig. 2.

Defining the state of the water spray type wiper tube 10 and the redundant segment 11 as a bending state when the wiper arm 30 is in an initial state; the state in which the water jet wiper tube 10 and the redundant segment 11 are present when the wiper arm 30 is in the farthest state is an extended state.

In order to allow the water jet wiper tube 10 extending above the vent flap to retract from an extended condition to a bent condition during the swinging of the wiper arm 30 from the most distal condition to the initial condition, the vehicle assembly provided herein further comprises a spring means 40. The spring means 40 is connected to the water jet wiper tube 10 to provide the pulling force required for the redundant section of the water jet wiper tube 10 to change from an extended state to a bent state. When the spring device 40 is specifically provided, the connection position of the spring device 40 and the water jet wiper tube 10 may be located on the side of the redundant segment 11 close to the through hole 21, and used to pull the redundant segment 11 of the water jet wiper tube 10 to a bent state.

Referring to fig. 1 and 2 together, when the wiper arm 30 is in the initial state as in fig. 1, the redundant segment 11 of the water jet wiper tube 10 is positioned below the vent flap 20 and assumes a bent state. When the water jet wiper starts to operate, the wiper arm 30 swings from an initial state. The wiper arm 30 drives the water-jet wiper tube 10 to slide out from the through hole 21. The portion of the water jet wiper tube 10 located below the vent flap 20 is pulled above the vent flap 20. The curvature exhibited by the redundant segment 11 is gradually stretched. During bending of the redundant segment 11, the spring means 40 connected to the redundant segment 11 are also stretched. When the wiper arm 30 swings to the furthest state as shown in fig. 2, the spring means 40 is stretched to the maximum deformation state in the working cycle, at the same time as the redundant segment 11 is unfolded. Of course, the redundant segment 11 may be fully or partially deployed, simply by providing a sufficient length of the water jet wiper tube 10 for swinging the wiper arm 30 to its furthest position.

After that, the wiper arm 30 starts to swing from the farthest state to the initial state. The length of the water jet wiper tube 10 required between the wiper arm 30 and the through hole 21 gradually decreases during the return of the wiper arm 30 to the initial state. During the swinging of the wiper arm 30 to the initial state, the partially exposed water jet wiper tube 10 is gradually pulled back under the vent flap 20 by the spring means 40. When the wiper arm 30 returns to the original state, the redundant segment 11 of the water jet wiper tube 10 assumes a bent state under the vent flap 20 under the pull of the spring device 40. Since the redundant section 11 of the water spray type wiper tube 10 is bent under the vent flap 20, the portion of the water spray type wiper tube 10 located above the vent flap 20 is not redundant, improving the appearance of the vehicle.

As can be seen from the above description, the redundant segment 11 can secure the maximum length of the water jet type wiper tube 10 required for the swing of the wiper arm 30 during the swing of the wiper arm. By pulling the water jet wiper 10 to slide in the through hole 21 by the spring means 40, it can be ensured that the remaining amount of the water jet wiper 10 is hidden under the vent flap 20. By hiding the allowance of the water spray wiper tube 10, the upper region of the vehicle vent flap 20 is more neat and the vehicle appearance is improved.

Referring to fig. 1, an end of the water spray type wiper tube 10 exposed through the through hole 21 is a connection end connected to the wiper arm 30. When the wiper arm 30 is in the initial state as shown in fig. 1, the vertical projection of the connection end on the plane of the through hole 21 coincides at least partially with the through hole 21. At least partial overlap is referred to as: the vertical projection of the connection end on the plane of the through hole 21 may be completely coincident with the through hole 21, or may be partially coincident with the through hole. The purpose of this is to keep the upper region of the vent flap 20 clean by shielding the through hole 21 as much as possible with the wiper arm 30.

Of course, the position of the through hole 21 in fig. 1 is only an alternative of the embodiment of the present application, and the through hole 21 may be opened on the vent flap 20, near the rotation shaft 50, or at other positions on the side of the wiper arm 30.

Referring to fig. 2, the spring device 40 includes a fixed end 41 and a movable end 42. The fixed end 41 is fixed to the vent flap 20, in particular to the side of the vent flap 20 facing away from the wiper arm 30. In the embodiment of the present application, the spring device 40 is directly fixed on the vent flap 20, and no additional supporting member is required to be separately arranged, so that the whole structure is relatively simple.

The arrangement of the spring device 40 provided in the embodiment of the present application is not limited to one way illustrated in fig. 2, but may be arranged in other ways. As in the alternative embodiment, a bracket may be provided on the vent flap 20 for securing the securing end 41, and the securing end 41 may be secured to other components of the vent flap 20 below that which are secured relative to the through-hole 21. The member fixed relative to the through hole 21 means a member having a fixed position relative to the through hole 21. Of course, the fixing means of the fixing end 41 may be an adhesive, a rivet, a screw fastener (bolt or screw) connection, or the like.

The movable end 42 is connected to the water jet wiper tube 10. Specifically, when the movable end 42 is connected to the water jet wiper tube 10, the connection position thereof is located on the side of the redundant segment 11 near the through hole 21. When the spring means 40 pulls the redundant segment 11 back to the bent state, the redundant segment 11 is located at the side of the movable end 42 facing away from the through hole 21.

In the embodiment of the present application, the movable end 42 may be directly fixed to the water-spraying wiper tube 10; it is also possible to provide a support on the water jet wiper tube 10, to which the movable end 42 of the spring means 40 is fixed.

It should be understood that, no matter what fixing manner is used for the fixing end 41 and the movable end 42, the positions of the fixing end 41 and the through hole 21 need to be relatively determined; the relative positioning of the movable end 42 on the water jet wiper tube 10 satisfies the need for the spring means 40 to pull the redundant segment 11 from the extended condition to the bent condition.

The spring means 40 may be a coil spring, a tension spring or other tension providing spring, which may be used in the embodiments of the present application.

The number of the spring devices can be different, such as 1, 2, 3, 4, etc. As an example, referring to fig. 1 and 3 together, fig. 3 is a bottom view of the underside of the vent flap, below the vent flap 20, two spring devices 40 are provided. The two spring 40 arrangements are symmetrically arranged on both sides of the water jet wiper 10. During the return of the redundant segment 11 of the water jet wiper tube 10 from the extended state to the bent state, the two spring devices 40 pull the redundant segment 11 on both sides of the water jet wiper tube 10 in a balanced manner and bend the redundant segment 11.

In the present embodiment, the two spring devices 40 are identical in structure. This is to prevent the redundant segment 11 from being bent due to uneven stress as much as possible because the two spring devices 40 provide approximately uniform tensile forces on both sides of the water spray wiper tube 10 during the return of the redundant segment 11 to the initial state.

Of course, the number of the spring devices 40 may be 1, 3, 4 or other numbers, and when the number of the spring devices 40 exceeds 1, the structures of the spring devices 40 may be all the same, or may not be the same. If one is a coil spring and the other is a tension spring; or both may be coil springs. In this embodiment, two or more spring devices 40 are required to provide the same or similar amount of tension.

As an alternative, the 2 spring means 40 are coil springs. Of course, the spring device 40 may be a tension spring or other springs capable of providing tension, may be a combination of a spring capable of providing tension and a section of connecting material for transmitting tension, or may be a spring material such as rubber directly instead of the spring. The elastic force of the spring device 40 may be provided by an elastic structure such as a coil spring or a tension spring, or may be provided by an elastic material such as rubber.

As an alternative, as shown in fig. 1, the vehicle assembly provided in the embodiment of the present application further includes a water pipe fixture 23 located below the vent flap 20. Specifically, the water pipe fixing device 23 is provided on the vent flap 20 at a side away from the through hole 21.

The water spray type wiper tube 10 is fixed by the water tube fixing device 23, and movement of a portion of the water spray type wiper tube 10 between the water tube fixing device 23 and the water tank storing the glass cleaning liquid is restricted. When the wiper arm 30 is in the initial state, the redundant segment 11 is restrained between the spring device 40 and the water tube fixture 23. In this way, the risk of interference of the redundant segment 11 with other components can be avoided as much as possible.

The water pipe fixing device 23 is directly fixed on the ventilation cover plate 20, and a supporting piece is not required to be arranged separately, so that the whole structure is relatively simple. It should be understood that, in the embodiment of the present application, the water pipe fixing device 23 may be fixed at other positions relatively fixed to the through hole 21; the fixing means may be bonding, riveting, welding, threaded fastener (bolt or screw) connection, etc.

Referring to fig. 1, the water pipe fixing device 23 is a circular ring-shaped water pipe buckle. Of course, the water pipe fixing device 23 may be another device capable of fixing the water jet wiper pipe 10, such as a pipe clip or a pipe clip.

As an alternative, the water spray wiper tube 10 is a tube made of wear-resistant nylon. During operation of the water jet type wiper, the water jet type wiper tube 10 needs to repeatedly pass through the through hole 21. The water spray type wiper tube 10 made of the common material can increase the resistance of the water spray type wiper tube 10 passing through the through hole 21 after being worn, and the water spray type wiper tube 10 made of the common material is difficult to maintain longer service life under the working condition of repeated passing. By using the water spray type wiper tube 10 made of wear-resistant nylon, the abrasion of the water spray type wiper tube 10 in the process of passing through the through hole 21 of the water spray type wiper tube 10 can be reduced, the smoothness of assembly operation is improved, and the service life of the water spray type wiper tube 10 is prolonged.

The wear-resistant nylon is a nylon modified plastic prepared by taking nylon resin as a base material and adding various antifriction materials for mixing. The common antifriction materials include graphite, molybdenum disulfide, polytetrafluoroethylene powder, silicon oil and the like, and the dosage is generally 3-15%.

As an alternative, as shown in fig. 1, the vehicle component provided in the embodiment of the present application further includes a bushing 22 disposed on the through hole 21, and the water spray wiper tube 10 is disposed through the bushing 22 and is slidable in the bushing 22. The bush 22 is engaged with the through hole 21. Of course, the bushing 22 and the through hole 21 may be fixed by adhesion or the like.

The through hole 21 is an opening in the vent flap 20. If the wear of the through hole 21 affects the movement of the water jet wiper 10, it is complicated to re-open the hole or replace the vent flap. The bush 22 is provided at the through hole 21 so that the water jet wiper tube 10 passes through the bush 22. If the bushing 22 wears, only a new bushing needs to be replaced, facilitating later maintenance.

Moreover, the height of the bushing 22 is less affected by the thickness of the vent flap 20. The two end faces of the bushing 22 can be provided with smoother transition areas, and wear of the water jet wiper tube 10 can be reduced to some extent. In the embodiment of the present application, the bushing 22 may be hollow cylindrical, hollow elliptic cylindrical, or the like.

As an alternative, the liner 22 is made of Polyoxymethylene (POM) material. Polyoxymethylene is a common nonmetallic material and is widely used in the automotive field. The density of the polyformaldehyde is far lower than that of metals such as iron, aluminum and the like, and the polyformaldehyde has hardness, strength and rigidity similar to those of metals, has good fatigue resistance, is rich in elasticity and has good chemical resistance.

The surface of the liner 22 has a Polytetrafluoroethylene (PTFE) coating. The polytetrafluoroethylene can resist acid, alkali and various organic solvents, has good thermal stability and extremely low friction coefficient. By using such a coating, friction between the inner wall of the bushing 22 and the water jet wiper tube 10 can be reduced, wear resistance of the bushing 22 can be improved, smoothness of assembly operation can be improved, and wear of the bushing 22 and the water jet wiper tube 10 can be reduced.

Embodiments of the present application also provide an automobile comprising a body, and a vehicle assembly as described above disposed on the body. In the technical scheme, the method comprises the following steps: the redundant section 11 can ensure the maximum length of the water spraying type wiper tube 10 required by swinging; the water spraying type wiper tube 10 is pulled to slide in the through hole 21 by the spring device 40, so that the allowance of the water spraying type wiper tube 10 can be ensured to be hidden below the ventilation cover plate 20; by hiding the allowance of the water spray wiper tube 10, the area above the vent flap 20 of the vehicle is more neat, improving the appearance of the vehicle.

The present disclosure is intended to embrace all such alternatives, modifications and variances which fall within the broad scope of the appended claims. Any omissions, modifications, equivalents, improvements, and the like, which are within the spirit and principles of the one or more embodiments of the disclosure, are therefore intended to be within the scope of the disclosure.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes or substitutions are intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
