Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

A vent trim 1, a wiper assembly, and a vehicle according to an embodiment of the present utility model are described below with reference to fig. 1 to 4.

As shown in fig. 1 to 3, a ventilation plaque 1 according to an embodiment of the present utility model includes: a trim body 11 and a shutter assembly 12. The plaque body 11 is provided with a mounting hole 111, the shielding component 12 covers the mounting hole 111, the shielding component 12 is provided with a through hole 1221, the projection of the through hole 1221 on the plaque body 11 is positioned in the mounting hole 111, the through hole 1221 is suitable for penetrating the wiper shaft 21, the shielding component 12 is movably connected to the inner side of the mounting hole 111, and the position of the through hole 1221 can be adjusted along the radial direction of the mounting hole 111. In other words, at least a portion of the shielding assembly 12 is adjustable in radial position along the mounting bore 111 to vary the position of the through bore 1221.

According to the ventilation decorative board 1 of the embodiment of the utility model, when the through hole 1221 is not concentric with the wiper shaft, the through hole 1221 can be adjusted to a proper position along the radial direction of the mounting hole 111, so that the problem that the part below the ventilation decorative board 1 is exposed due to the fact that a larger hole is formed in the ventilation decorative board 1 is avoided, and the shielding effect of the ventilation decorative board 1 is improved. Therefore, the ventilation plaque 1 of the embodiment of the utility model does not interfere with the wiper shaft 21, and the shielding effect is good.

It will be appreciated that the wiper 2 includes a driving member (not shown), a wiper shaft 21 and a wiper lever 22, and that the driving member drives the wiper shaft 21 to rotate, thereby swinging the wiper lever 22. In the related art, as shown in fig. 4, in order to avoid the abnormal noise generated between the wiper 2 and the ventilation ornamental plate 1 during the working process, the clearance between the ventilation ornamental plate 1 and the wiper shaft 21 is generally more than 6mm, so that the shielding effect of the ventilation ornamental plate 1 is poor, the internal structure is visible, and the appearance perception is poor. On the other hand, tolerance stack-up causes misalignment of the wiper shaft 21 and the mounting hole 111 on the vent trim 1 due to poor assembly accuracy of the wiper 2, and poor appearance perception.

The ventilation plaque 1 of the embodiment of the utility model can adjust the position between the through hole 1221 and the wiper shaft 21 by changing the relative position of the shielding component 12 and the mounting hole 111, so that the problem of exposing parts below the mounting hole 111 can be reduced, and the problem of interference between the through hole 1221 and the wiper shaft 21 can be avoided, so that the ventilation plaque 1 has better use effect.

Wherein, the position of at least part of the shielding component 12 relative to the mounting hole 111 can be adjustable, and the position of the whole shielding component 12 relative to the mounting hole 111 can be adjustable, so that the through hole 1221 on the shielding component 12 can synchronously move. It is also possible that the position of the screen assembly 12 relative to the mounting hole 111 is adjustable only at the position of the through hole 1221 so that the through hole 1221 is concentric with the wiper shaft 21.

In some embodiments, as shown in fig. 1 and 2, the shielding assembly 12 includes a shielding ring 121 and a collar 122, an outer ring of the shielding ring 121 is connected with the plaque body 11, the collar 122 is mounted on an inner ring of the shielding ring 121, a through hole 1221 is formed in the collar 122, and the collar 122 can be adjusted in position along a radial direction of the mounting hole 111. It will be appreciated that the shroud ring 121 is fixed relative to the fascia body 11, and the collar 122 is movable relative to the shroud ring 121, so that when the through hole 1221 in the collar 122 is not concentric with the assembled wiper shaft 21, the relative position of the collar 122 can be adjusted, thereby facilitating the installation and adjustment of the shroud assembly 12, and facilitating the manufacturing process.

Alternatively, as shown in fig. 1 and 2, the outer circumference of the shielding ring 121 is connected to the inner circumference of the mounting hole 111, and the shielding ring 121 is injection-molded with the trim body 11 as one piece. It will be appreciated that the outer peripheral edge of the shield ring 121 is connected to the inner peripheral edge of the mounting hole 111. The shielding ring 121 is integrally formed with the trim body 11. For example, the shielding ring 121 and the decoration plate body 11 can be integrally connected in a double-shot molding manner, so that the connection strength of the shielding ring 121 and the decoration plate body 11 can be improved, and the service life of the ventilation decoration plate 1 can be prolonged.

In some embodiments, as shown in fig. 1 and 2, the outer peripheral wall of the collar 122 is provided with an annular clamping groove 1222, the axis of the annular clamping groove 1222 is arranged coaxially with the axis of the collar 122, the inner ring of the shielding ring 121 extends into the annular clamping groove 1222, and the distance that the inner ring of the shielding ring 121 extends into the annular clamping groove 1222 is adjustable. It will be appreciated that collar 122 is arranged to snap-fit with the inner race of shroud ring 121, thereby facilitating installation and removal of collar 122. In addition, since the distance that the inner ring of the shielding ring 121 extends into the annular clamping groove 1222 is adjustable, when the through hole 1221 on the collar 122 is not concentric with the assembled wiper shaft 21, the distance that the inner ring of the shielding ring 121 extends into the annular clamping groove 1222 can be adjusted, so that the position adjustment of the collar 122 is more convenient.

Optionally, as shown in fig. 2, a minimum overlapping distance H between the inner ring of the shielding ring 121 and the annular clamping groove 1222 is greater than or equal to 0.8mm and less than or equal to 1.0mm. For example, the assembly tolerance of the wiper shaft 21 is ±2.1mm, and when the wiper shaft 21 deviates by 2.1mm, the overlap amount of the collar 122 and the inner ring of the shielding ring 121 is 0.9mm, so that the inner ring edge of the shielding ring 121 can be ensured not to be exposed, and the reliability of the connection of the collar 122 and the shielding ring 121 is improved.

In some embodiments, as shown in fig. 1 and 2, the shielding ring 121 is an elastic member, and the shielding ring 121 can be elastically deformed to change the position of the collar 122. It can be appreciated that, because the shielding ring 121 has elasticity, when the wiper shaft 21 is not concentric with the mounting hole 111 of the trim body 11, the wiper shaft 21 drives the shielding ring 121 to deviate through the collar 122, so that one side of the shielding ring 121 is compressed, and the other side is stretched, thereby absorbing the assembly tolerance of the wiper shaft 21 and improving the mounting effect of the ventilation trim 1 and the wiper shaft 21.

Alternatively, as shown in fig. 1 and 2, the shielding ring 121 is wavy in the radial direction of the through hole 1221, in other words, the shielding ring 121 is wavy in the outer circumferential profile of the cross section parallel to the axial direction of the through hole 1221. It will be appreciated that the shielding ring 121 is generally W-shaped in cross-section parallel to the axial direction of the through bore 1221, thereby facilitating deformation of the shielding ring 121 and providing a good tolerance absorbing effect. For example, the shielding ring 121 is made of soft rubber, so that the shielding ring 121 is convenient to elastically deform, and the processing and manufacturing are simple and the cost is low.

A wiper assembly according to another embodiment of the present utility model includes a vent trim 1 and a wiper 2, the wiper 2 including a driving member (not shown), a wiper shaft 21, and a wiper lever 22. The ventilation plaque 1 is the ventilation plaque 1 of the utility model, the driving piece is connected with the wiper rod 22 through the wiper shaft 21, and the wiper shaft 21 is arranged through the through hole 1221.

According to the wiper assembly of the embodiment of the utility model, when the through hole 1221 is not concentric with the wiper shaft, the through hole 1221 can be adjusted to a proper position along the radial direction of the mounting hole 111, so that the problem that the part below the ventilation decorative plate 1 is exposed due to the fact that a larger hole is formed in the ventilation decorative plate 1 is avoided, and the shielding effect of the ventilation decorative plate 1 is improved. Therefore, the wiper assembly of the embodiment of the utility model does not interfere with the wiper shaft 21, and has a good shielding effect.

In some embodiments, the wiper shaft 21 is in clearance fit with the through hole 1221, and a clearance between an outer wall of the wiper shaft 21 and an inner wall of the through hole 1221 is 0.4mm or more and 0.6mm or less. For example, the gap between the outer wall of the wiper shaft 21 and the inner wall of the through hole 1221 may be 0.4mm, 0.5mm, or 0.6mm. In the embodiment of the present utility model, the gap between the outer wall of the wiper shaft 21 and the inner wall of the through hole 1221 is 0.5mm, so that it is possible to ensure that the inner structure of the wiper 2 is not exposed and interference is not caused to the wiper shaft 21.

A vehicle according to another embodiment of the utility model includes a wiper assembly of the utility model.

According to the vehicle of another embodiment of the present utility model, when the through hole 1221 is not concentric with the wiper shaft, the through hole 1221 can be adjusted to a proper position along the radial direction of the mounting hole 111, so that the problem of exposing the parts below the ventilation decorative board 1 caused by forming a larger hole in the ventilation decorative board 1 is avoided, and the shielding effect of the ventilation decorative board 1 is improved. Therefore, the wiper assembly of the embodiment of the utility model does not interfere with the wiper shaft 21, and has a good shielding effect.
