[0008] Further, the two sides of the end of the protrusion away from the upper shell are inclined to the middle part of the protrusion.

[0009] Further, the included angle between the inclined surface of the protrusion and the cross section of the protrusion is 58-62 degrees.

[0010] Further, the inclined surfaces on the two sides of the protrusion are chamfered.

[0011] Further, the lower shell is provided with a first hollow groove in communication with the groove, the upper shell is provided with a second hollow groove corresponding to the first hollow groove, the upper shell and the lower shell are spliced to make the first hollow groove and the second hollow groove communicate to form a cavity, and the sealing ring is provided with an extension part matched with the cavity on the two sides.

[0012] The utility model has the advantages that:

[0013] This utility model's sealing ring can cover both sides of the strip-shaped protrusion, using side compression to seal, increasing the sealing contact area and improving the sealing effect.

[0014] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0021] Example 1, as Figures 1-2 As shown, this utility model provides a highly sealed automotive battery protection box, including: an upper shell 1 and a lower shell 2 spliced ​​with the upper shell 1. The upper shell 1 is provided with a strip-shaped protrusion 3 arranged around the upper shell 1. The lower shell 2 is provided with a groove 4 that can accommodate the protrusion 3. The protrusion 3 and the groove 4 cooperate to splice the upper shell 1 and the lower shell 2. A sealing ring 5 that can wrap the cross section of the protrusion 3 is installed in the groove 4.

[0022] In the scheme, when splicing the upper shell 1 and the lower shell 2, the sealing ring 5 is placed in the groove 4, or the sealing ring 5 is wrapped on the protrusion 3, then the protrusion 3 is correspondingly placed in the groove 4, so that the upper shell 1 and the lower shell 2 are spliced into a whole, then the upper shell 1 and the lower shell 2 are fixed through bolts or buckles, at this time the sealing ring 5 can wrap the both sides of the strip-shaped protrusion 3, the side surface is pressed to seal, the sealing contact area is increased, and the sealing effect is improved.

[0023] In an embodiment of the utility model, the both sides of protrusion 3 far away from the end of upper shell 1 are obliquely arranged to the middle part of protrusion 3, wherein the included angle between the inclined surface of protrusion 3 and the cross section of protrusion 3 is 58°-62°.

[0024] In the scheme, the end of protrusion 3 far away from the upper shell 1 is obliquely arranged to form a sharp end, so as to facilitate the installation of protrusion 3 in sealing ring 5.

[0025] In an embodiment of the utility model, the both sides of protrusion 3 are chamfered to reduce the damage to sealing ring 5 caused by the extrusion of protrusion 3 to sealing ring 5.
