A connection assembly 100 according to a first aspect of the invention, as shown in fig. 5 to 9, comprises:
a dimming plane 110 and a dimming support 120, wherein the dimming plane 110 and the dimming support 120 are pivotally connected therebetween, and one of the dimming plane 110 and the dimming support 120 is detachably connected to the other by deformation.
The matching mode can simplify the connection structure between the dimming aircraft 110 and the dimming support 120, save a large amount of installation space, reduce the use of standard parts, save cost, have strong reliability and are not easy to fall off.
In an example of the present invention, a pivot shaft 111 is disposed on one of the dimming aircraft 110 and the dimming support 120, a pivot hole 121 which is cooperatively connected with the pivot shaft 111 is disposed on the other of the dimming aircraft and the dimming support, and the pivot shaft 111 is cooperatively connected with the pivot hole 121 through deformation;
for example, a pivot shaft 111 is disposed on the dimming aircraft 110, and a pivot hole 121 which is engaged with the pivot shaft 111 is disposed on the dimming bracket 120;
for another example, the light control bracket 120 is provided with a pivot shaft 111, and the light control aircraft 110 is provided with a pivot hole 121 which is engaged with the pivot shaft 111;
the dimming support 120 is hooped in the pivot shaft 111 of the dimming aircraft 110 through a pivot hole 121, so that structures such as a ball screw and a ball nut in the conventional scheme are omitted, and structures such as a ball nut matching structure and a small ear of a dimming large support in the conventional scheme are omitted;
behind the dimmed aircraft 110, and also on the same principle as in the conventional solution, the dimmed aircraft is propelled through the dimmed screw, the dimmed gear. In view of the structure of the connection between the dimming aircraft 110 and the dimming support 120, the dimming aircraft 110 can not only push the dimming support 120 to rotate, but also the dimming support 120 is hooped inside the pivot 111 and is not easy to fall off, so that a small ear of the dimming support 120 is omitted.
As shown in fig. 6, the connection structure at the position Q of the dimming support 120 and the dimming aircraft 110 requires only about 10mm in lateral space, so that much space is saved with respect to the conventional scheme at the position Q' in fig. 1, and therefore, the dimming structure can be smoothly arranged even if the space is not sufficient;
the connection mode of the dimming aircraft 110 and the dimming bracket 120 can be simplified through the matching mode of the pivot shaft 111 and the pivot hole 121, so that the connection space is greatly saved, and the installation is convenient and the reliability is high.
In one example of the present invention, the pivot shaft 111 includes:
the hinge comprises a hinge body 1111 and an elastic layer 1112 coated on the outer contour of the hinge body 1111, wherein when the pivot hole 121 is matched with the pivot shaft 111, the elastic layer 1112 is extruded by the pivot hole 121 to be deformed;
that is to say, the pivot shaft 111 is matched with the pivot hole 121 through the deformation of the pivot shaft 111, and then the matching connection between the pivot shaft 111 and the pivot hole 121 is realized, so that the rotation connection between the pivot shaft 111 and the pivot hole 121 can be realized, and the falling-off between the pivot shaft 111 and the pivot hole can be avoided.
In one example of the present invention, the inner diameter of the pivot hole 121 gradually increases from the side close to the pivot shaft 111 to the side away from the pivot shaft 111, and the inner diameter of the pivot hole 121 close to one end of the pivot shaft 111 is smaller than the outer diameter of the pivot shaft 111;
the amount of deformation of the pivot shaft 111 due to extrusion is large at the initial stage of the fitting of the pivot shaft 111 and the pivot hole 121, and the amount of deformation of the pivot shaft 111 gradually decreases with the advancement of the pivot shaft 111; certainly, after the assembly of the pivot shaft 111 and the pivot hole 121 is completed, the deformation amount between the pivot shaft 111 and the pivot hole 121 may be zero, and a clearance fit is formed between the pivot shaft 111 and the pivot hole 121, that is, after the fit is completed, the outer diameter of the elastic layer 1112 on the pivot shaft 111 is larger than the inner diameter of the pivot hole 121 close to one end of the pivot shaft 111, in short, under the case of the clearance fit embodiment, the maximum outer diameter of the elastic layer 1112 is larger than the inner diameter of the pivot hole 111 close to the one end of the pivot shaft 111 and smaller than the size of the end far away from the pivot shaft 111, so that the pivot shaft 111 may be limited on the pivot hole 121, the pivot shaft 111 and the pivot hole 121 are prevented from falling off, the reliability of connection between the pivot shaft 111 and the pivot hole 121 is improved, and the whole mechanism can be prevented from falling off the lamp body.
In one example of the present invention, the elastic layer 1112 is a rubber;
for example, the elastic layer 1112 can be connected to the spindle body 1111 by injection molding, which avoids the trouble of assembly and has high reliability.
It is understood that the elastic layer 1112 may cover the entire spindle body 1111, or may be disposed at intervals along the length direction of the spindle body 1111.
Preferably, the outer contour of the elastic layer 1112 is configured to have an outer diameter near the middle portion larger than that at the two ends, so that the fit with the pivot hole 121 can be better achieved, and the reliability of the connection between the two can be further improved.
In an example of the present invention, a recess 112 with an open end is opened on the dimming aircraft 110 or the dimming bracket 120 configured with a pivot axis 111, the pivot axis 111 is configured in the recess 112, when the dimming aircraft 110 and the dimming bracket 120 are both configured, the dimming aircraft 110 or the dimming bracket 120 configured with a pivot hole 121 is at least partially located in the recess 112;
therefore, the space occupied by the connection between the dimming aircraft 110 and the dimming support 120 can be reduced, the overall connection thickness is greatly reduced, and the connection compactness between the dimming aircraft and the dimming support is improved.
In one example of the present invention, the open end 113 of the slot 112 has a span L that is greater than the width of the dimmed aircraft 110 or the dimmed cradle 120 that mates with the slot 112, such that the dimmed aircraft 110 or the dimmed cradle 120 can rotate within the slot 112;
this may facilitate rotation of the dimming mount 120 within the recess 112 of the dimming aircraft 110, increasing flexibility in connection of both the dimming mount 120 and the dimming aircraft 110.
In one example of the present invention, the length of the pivot shaft 111 is less than the depth of the pivot hole 121; this allows the pivot shaft 111 to be located in the pivot hole 121, preventing the pivot shaft 111 from protruding out of the pivot hole 121, and saving space for the connection between the dimming plane 110 and the dimming stand 120.
According to the second aspect of the present invention, the light adjusting mechanism includes the connecting assembly 100, and the connecting assembly 100 can save a large amount of installation space, reduce the use of standard components, save cost, facilitate installation, have high reliability, and prevent the light adjusting mechanism from falling off.
According to the third aspect of the invention, the vehicle lamp comprises the dimming mechanism, and the dimming mechanism can save a large amount of installation space, reduce the use of standard parts, save cost, is convenient to install, has strong reliability and is not easy to fall off.
The exemplary embodiments of the connection assembly 100, the dimming mechanism and the vehicle lamp proposed by the present invention have been described in detail with reference to the preferred embodiments, however, it will be understood by those skilled in the art that various modifications and changes can be made to the above specific embodiments and various combinations of the technical features and structures proposed by the present invention can be made without departing from the concept of the present invention, and the scope of the present invention is determined by the appended claims.
