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 are further described in detail with reference to the specific embodiments, and fig. 1 and fig. 2 respectively show the explosion schematic diagram and the three-dimensional assembly schematic diagram of the vehicle-mounted camera housing structure with good shielding performance of the present invention, it can be known that the vehicle-mounted camera housing structure mainly comprises a housing body 1, a board end connector 2, an external connector 3, and other parts, wherein, as shown in fig. 3 and fig. 4, the external connector 3 comprises a connection terminal 31, an insulation column 32, and a metal housing 33, and is arranged along the radial direction thereof according to the order. The metal case 33 is inserted and fixed to the case body 1. And the board end connector 2 is arranged in the cavity of the shell body 1 and is plugged with the external connector 3 so as to realize the transmission of video signals. Here, it is to be emphasized that the vehicle-mounted camera outer housing structure is additionally provided with a shielding plate 4 (as shown in fig. 8). The shield plate 4 is disposed in the cavity of the housing body 1. The metal shell 33 passes through the shielding plate 4 and is electrically connected with the shielding plate 4 to conduct current (as shown in fig. 3 and 4). Therefore, the vehicle-mounted camera has good shielding performance, the influence of external electromagnetic interference on a signal transmission process is effectively reduced, the reliability and stability of signal transmission are ensured, and the vehicle-mounted camera has excellent high-frequency performance.

When carrying out actual design to the on-vehicle camera shell body structure that shielding performance is good, can adopt multiple mode in order to realize the electric conduction of metal casing 33 and shield plate 4, for example, comparatively common is: the shield plate 4 and the metal shell 33 may be electrically connected by a wire. However, in the practical application environment, the vehicle-mounted camera inevitably receives the impact force and the vibration force, so that the welded joint of the lead is easily broken due to pulling, and the actual shielding stability and effect of the outer shell structure of the vehicle-mounted camera are affected. In view of this, as a preferable solution, the conductive sponge 5 is packed between the shielding plate 4 and the metal case 33 (as shown in fig. 1, 2, 3, 4, 9). It is known that the conductive sponge 5 is produced by a polymer composite foaming technology, and has the advantages of uniform foaming pore diameter, softness, high elasticity, no desquamation and corrosion resistance. By adopting the technical scheme, on one hand, the shielding plate 4 is electrically connected with the metal shell 33 in a simpler mode, so that the assembly is convenient, and the subsequent replacement and maintenance are convenient; on the other hand, the shield plate 4 and the metal case 33 are electrically connected to each other with good vibration resistance, and stability of signal conduction is ensured.

In order to reduce the assembling difficulty of the vehicle-mounted camera outer shell structure and the mounting difficulty of the conductive sponge 5 and ensure the conductive stability of the shielding plate 4 and the metal shell 33, the structure of the metal shell 33 is further refined and sequentially formed by sequentially connecting the insertion section 331, the connection transition section 332 and the insertion section 333 along the top-down direction. The connecting transition section 332 penetrates the shielding plate 4, and the insertion section 331 and the insertion section 333 are respectively disposed on the upper and lower sides of the shielding plate 4. The housing body 1, the shielding plate 4, the connecting transition section 332 and the inserting section 333 together enclose a cavity. The conductive sponge 5 is filled in the cavity (as shown in fig. 2, 3, 4, 7 and 9).

It should be noted that, in addition to the conductive sponge 5, the conductive body for conducting the shielding plate 4 and the metal shell 33 may also be conductive rubber, carbon graphite tubes, silver nanowire aerogel, or the like according to practical situations.

Further, in view of reducing the molding cost and the difficulty in the subsequent assembly of the shield plate 4, the housing body 1 is preferably a split structure including an upper housing 11 and a lower housing 12 integrally connected. The shield plate 4 is sandwiched between the upper housing 11 and the lower housing 12, so that a secure fixation of its position is achieved (as shown in fig. 1, 2, 3, 4).

As the technical scheme, the vehicle-mounted camera outer shell structure with good shielding performance is further optimized, and an elastic rubber pad 6 is additionally arranged. An elastic rubber pad 6 is elastically sandwiched between the shield plate 4 and the lower case 12 (as shown in fig. 1, 2, 3, 4). Due to the elastic rubber pad 6, on one hand, the shielding plate 4 is always kept in an elastic compression state, and damage to a lower assembly matching surface of the shielding plate due to overlarge pretightening force is avoided; on the other hand, make shell body 1 have better waterproof performance on the whole, prevent that it from entering into the inside of on-vehicle camera by the fit-up gap.

In the case where the waterproof performance is required to be higher, the elastic rubber gasket 6 may be provided on both sides, that is, between the shield plate 4 and the upper case 11 and between the shield plate 4 and the lower case 12.

In the practical application process of the vehicle-mounted camera, part of water or moisture still enters through the gap between the shielding plate 4 and the upper shell 11, and corrodes the conductive foam 5 or other types of conductors, so that the electrical conduction stability of the shielding plate 4 and the metal shell 33 is affected to a certain extent, and in view of this, as a further optimization of the vehicle-mounted camera outer shell structure with good shielding performance, a waterproof sealing ring 7 (as shown in fig. 10) may be further added. The waterproof gasket 7 is disposed around the periphery of the metal shell 33 and is pressed between the upper shell 11 and the shield plate 4 (as shown in fig. 1, 2, 3, 4).

In order to ensure the positioning reliability of the waterproof gasket 7 and prevent the waterproof gasket 7 from being misaligned or twisted during the assembly process, a receiving groove 111 may be extended upward from the top wall of the upper housing 11 to receive the waterproof gasket 7 (as shown in fig. 6).

Finally, it should be noted that it is known to adopt various ways to realize the connection and fixation between the upper shell 11 and the lower shell 12, for example: snap-in or screw-on, but here an easy-to-implement, quick-to-assemble embodiment is recommended, as follows: the upper case 11 and the lower case 12 are fixed by means of coupling bolts 13. Correspondingly, the upper case 11 is provided with a connecting through hole for the connecting bolt 13 to pass through, the lower case 12 is provided with a threaded hole for the connecting bolt 13 to be screwed, and the shielding plate 4 is provided with a through hole for the connecting bolt 13 to pass through (as shown in fig. 2, 3, 5, 6 and 8).

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
