The available space for installation in a vehicle is limited, and in the limited space, the hardware layout requires a sufficiently large circuit board area, while the peripheral space is limited. The existing practice generally includes two types, one of which is: the thickness of the cover body is increased at the butt joint part of the upper and lower shells or the upper and lower cover bodies, so that the contact surface is increased, the groove is correspondingly arranged on the contact surface to position the sealing ring, and the sealing ring is prevented from deviating; the other one is as follows: as shown in fig. 1, a groove is directly formed on a contact surface of a butt joint of a lower cover body 02, and a sealing ring 03 is arranged between the upper cover body 01 and the lower cover body 02, but due to limited installation space, the thicknesses of the upper cover body 01 and the lower cover body 02 are always on the millimeter level, the size of the groove is smaller, the groove on the upper cover body 01 is difficult to form, especially for die castings, the difficulty of die opening is increased due to the fact that a die of the groove part needs to be made of thin ribs, the thin ribs are prone to edge breakage, the service life of the die is affected due to the fact that the groove cannot be formed, and therefore the requirement of high yield of production and processing is difficult to meet due to the fact.

This application provides a shell butt-joint structural based on this basis, includes: an upper cover body 100, a lower cover body 200 and a seal ring 300; the upper cover body 100 and the lower cover body 200 are butted to form an inner cavity 110 for accommodating the circuit board 400 in a surrounding manner, a first notch 120 with an opening facing the inner cavity 110 is formed on an end surface 130 of the butting end of the upper cover body, and the sealing ring 300 is partially positioned in the first notch 120, so that when the upper cover body 100 and the lower cover body 200 are butted and pressed against the sealing ring 300, the sealing ring 300 is butted against the circuit board 400.

Illustratively, as shown in fig. 2 and 3, the housing docking structure includes a sealing ring 300, an upper cover 100 and a lower cover 200, and the sealing ring 300 is located between the upper cover 100 and the lower cover 200 in order to facilitate sealing at the docking position between the upper cover 100 and the lower cover 200. The upper cover body 100 and the lower cover body 200 can form a cylindrical structure after being butted, a hollow inner cavity 110 is correspondingly formed by enclosing in the cylindrical structure, and parts related to the camera and needing to be sealed, such as a circuit board 400 and the like, can be correspondingly placed in the inner cavity 110.

The sealing part is located between the end face 130 of the butt joint end of the upper cover body and the butt joint end of the lower cover body 200, the limiting part is located in the first notch 120 formed at the butt joint end of the upper cover body 100, and the two parts are connected with each other, so that when the upper cover body 100 is in butt joint with the lower cover body 200, the limiting part can be limited through the first notch 120, and then the limiting part is also limited, the sealing ring 300 is positioned, and the deviation of the sealing ring in the direction away from the inner cavity 110 is avoided. Meanwhile, the position of the circuit board 400 arranged in the inner cavity 110 can be just located at the position of the sealing ring 300 or the butt joint, the circuit board 400 can be matched with the shape of the cross street surface of the inner cavity 110, and thus, in the butt joint and compression process of the upper cover body 100 and the lower cover body 200, the sealing ring 300 located between the upper cover body 100 and the lower cover body 200 can be gradually extruded, so that the deformable sealing ring 300 can be completely and tightly filled in a gap between the upper cover body 100 and the lower cover body 200, and meanwhile, the deformed sealing ring 300 can be abutted against the circuit board 400 in the inner cavity 110, and therefore, the sealing ring 300 can be limited along the direction close to the inner cavity 110, and the deviation of the sealing ring 300 to the direction close to the.
