Detailed Description

Referring to fig. 1-5, the present invention relates to a vehicle-mounted host with excellent sealing performance, which comprises a host casing 1 with an opening, a host sealing ring 2 arranged at the edge of the opening in a sealing manner, a host sealing cover 3 covering the host sealing ring 2 and hermetically fitting with the host casing 1, and a main board embedded in the host casing 1; and the surface of the host machine sealing cover 3 is provided with a plurality of data connecting interfaces 4 connected with the mainboard; the bottom edge of the host sealing cover 3 is provided with a plurality of arch bridge-shaped baffles 31 extending into the host shell 1, and the arch bridge-shaped baffles 31 are tightly attached to the inner side wall of the host sealing ring 2.

Because the conventional vehicle-mounted host is not provided with a further sealing structure, when the host sealing cover 3 covers the opening of the host shell 1, the host sealing ring 2 of the conventional vehicle-mounted host deforms when stressed, so that the host sealing ring 2 may not be completely sealed in the opening of the host shell 1; in the application, when the main machine sealing ring 2 is stressed, even if the main machine sealing ring 2 deforms, the arch bridge-shaped baffle 31 is arranged, so that the main machine sealing ring 2 can be prevented from being separated from the opening of the main machine shell 1; even more serious deformation (break away from host computer casing 1's opening and remove toward host computer casing 1 simultaneously) takes place for host computer sealing washer 2 simultaneously, the arch bridge form baffle 31 that this application extended to in the host computer casing 1 still can paste tightly with the host computer sealing washer 2 of deformation, can guarantee furthest's leakproofness.

Referring to fig. 1 to 5, further, in order to ensure stable connection of the main housing 1, the main sealing ring 2, and the main sealing cover 3, a plurality of first screw holes 11 are uniformly disposed at an opening edge of the main housing 1, a plurality of second screw holes 21 aligned with the first screw holes 11 are disposed on a surface of the main sealing ring 2, a plurality of third screw holes 33 aligned with the second screw holes 21 are disposed on a surface of the main sealing cover 3, and axes of the first screw holes 11, the second screw holes 21, and the third screw holes 33 aligned with each other are the same.

Referring to fig. 2, further, since the main sealing ring 2 is generally stressed and deformed more severely between the two second screw holes 21 after screwing, the arch bridge-shaped baffle 31 is located between the two third screw holes 33 in this embodiment to address this phenomenon.

Referring to fig. 5, further, in order to avoid the displacement between the main body seal ring 2 and the main body seal cover 3, in the present application, the main body seal ring 2 includes a ring of seal ring seat 211 corresponding to the opening profile of the main body housing 1, and a snap seal ring 212 integrally formed on the seal ring seat 211, wherein the width of the snap seal ring 212 is smaller than the width of the seal ring seat 211; the bottom of the main machine sealing cover 3 is provided with a circle of clamping grooves 32 for assembling clamping sealing rings 212, namely the clamping sealing rings 212 are assembled in the clamping grooves 32.

Referring to fig. 5, in order to further increase the matching degree and the sealing performance between the main body sealing ring 2 and the main body sealing cover 3, a sealing protrusion 321 extending along the slot 32 is disposed in the slot 32.

Referring to fig. 3, in order to increase the sealing performance between the main seal ring 2 and the main housing 1 and prevent the main seal ring 2 and the main housing 1 from shifting, a circle of inner engaging protrusions 111 and outer engaging protrusions 112 located outside the inner engaging protrusions 111 are disposed on the surface of the opening of the main housing 1, wherein an engaging groove is formed between the inner engaging protrusions 111 and the outer engaging protrusions 112.

Referring to fig. 5, further, in order to facilitate the installation of the main board of the vehicle-mounted host, in the present embodiment, a main board fixing block 34 extending into the host casing 1 is disposed at the bottom of the host sealing cover 3, and a fixing post 341 is disposed at the end of the main board fixing block 34 close to the host casing 1. Generally, fixing holes are formed in two sides of the main board, and the corresponding fixing columns 341 are inserted into the fixing holes of the main board to realize the assembly between the main machine sealing cover 3 and the main board.

Referring to fig. 3, in order to fix the main board, a main board slot 12 for fixing the main board is disposed on both inner sidewalls and a bottom of the main housing 1. The mainboard setting is in the inside of host computer casing 1 promptly, and the mainboard can block to be established in mainboard draw-in groove 12, has guaranteed promptly at the vehicle at the stroke in-process, and the mainboard can not rock the condition of aversion, because the fixed column 341 of the sealed lid 3 of host computer is pegged graft in the fixed orifices of mainboard, when needs maintenance promptly, only need with the sealed lid 3 of host computer directly take out can.

The above embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by the technical solution of the present invention by those skilled in the art are all within the scope of the present invention as defined by the claims.
