Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description of the present invention and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The contents of the present invention will be further described in detail with reference to the following embodiments, and fig. 1 and fig. 2 show an exploded view and a three-dimensional assembly view of a first embodiment of the on-board lens for automatically deicing, defrosting and defogging according to the present invention, respectively, and it can be seen that the on-board lens mainly comprises a lens barrel 1, an imaging component 2, a first electric heating component 3, and a pressing ring 4 sleeved on the periphery of the lens barrel 1. Wherein, an accommodating chamber 11 is provided in the lens barrel 1. The imaging assembly 2 is arranged in the accommodating cavity 11 and is pressed and fixed by the pressing ring 4. The imaging assembly 2 comprises a first lens 21, a second lens 22 and a spacer ring 23 arranged in sequence from outside to inside. It is important to note that the first electric heating element 3 comprises a first electric heating element 31 and a first wire 32. The first wire 32 provides electric support for the first electric heating element 31, and it passes through the lens barrel 1 to realize electric connection with the first electric heating element 31. The first electric heating element 31 is arranged around the periphery of the imaging area of the second lens 22, and is sandwiched between the first lens 21 and the second lens 22 (as shown in fig. 3 and 4). Thus, the temperature of the imaging assembly 2 is effectively increased, the tendency of condensation of water vapor in the imaging area on the imaging assembly is reduced, and in addition, the first electric heating element 31 of the first electric heating assembly 3 is arranged in the non-imaging area, so that the influence of the first electric heating element 31 itself and the condensed ice, frost and water mist on the light transmittance of the imaging assembly is avoided, and the imaging quality is ensured.

The second wire 52 provides electric support for the second electric heating element 51, and it also passes through the lens barrel 1 to realize electric connection with the second electric heating element 51. The second electric heating element 51 is arranged around the periphery of the imaging area of the first lens 21 and clamped between the first lens 21 and the pressing ring 4, so that the temperature rise speed of the imaging assembly 2 is further improved, the moisture is prevented from condensing on the outer side surface of the first lens 21, and the imaging quality is ensured.

However, it should be emphasized that when the pressing ring 4 and the lens barrel 1 are screwed together by the screw pair, the second electric heating element 51 is inevitably rotated by the action of the circumferential moment, so that it is easily separated from the second wire 52, and the power supply is interrupted, and therefore, the above embodiment is only applicable to a scene where the pressing ring 4 and the lens barrel 1 are fastened and fixed.

As can be seen from fig. 5, the lens barrel 1 has a through hole 12 formed therein along the longitudinal direction thereof for passing the first lead wire 32 and the second lead wire 52 therethrough. And the through hole 12 is communicated with the containing cavity 11. Therefore, the lens barrel 1 is reasonable in design structure, injection molding of the lens barrel is facilitated, and molding quality is ensured; in addition, routing of the first and

second conductors

32, 52 during assembly is also facilitated.

Here, it should be noted that each of the first electric heating element 31 and the second electric heating element 51 may preferably be any one of a resistance heating ring, an electric heating sheet, and an electric heating film.

Fig. 6 shows a schematic structural diagram of a third embodiment of the on-vehicle lens for automatically deicing, defrosting and demisting, which is different from the second embodiment in that: 1) the buffer ring 6 is additionally arranged in the accommodating cavity 11 and is pressed against the bottom wall of the second lens 22, so that the second lens 22 has certain elastic pretightening force, and therefore, on one hand, the second lens 22 is prevented from being broken under the action of excessive pretightening force; on the other hand, the probability of the phenomenon that the second lens 22 is not pressed due to the assembly problem is reduced to a certain extent, and the requirement on the axial matching size of the pressing ring 4 and the lens barrel 1 is reduced. 2) The sealing ring 7 is additionally arranged and attached to the pressing ring 4 and is just opposite to the annular pressing area corresponding to the first lens 21, so that the self sealing performance of the vehicle-mounted lens is further improved, and water vapor is prevented from entering the imaging assembly 2.
