By applying the technical solution of the present embodiment, by disposing the mounting portion 30 of the sealing structure in the mounting groove 11 of the first mounting member 10, at least two sealing protrusions 41 of the sealing portion 40 of the sealing structure are respectively abutted against the second mounting member 20. Because the sealing lug 41 is hollow structure, and sealing lug 41 is made by elastic material, when first installation component 10 and second installation component 20 are assembled, can extrude two at least sealing lugs 41 respectively like this to make two at least sealing lugs 41 all take place elastic deformation, and then make two at least sealing lugs 41 fill the clearance department between first installation component 10 and second installation component 20, in order to realize sealing the clearance between first installation component 10 and the second installation component 20, and then in order to solve the battery compartment among the prior art because of the leakproofness is not good leads to the problem in the liquid leakage.

Alternatively, the sealing section of the sealing portion 40 gradually decreases along the extending direction of the mounting portion 30 to the sealing portion 40; in this way, when the mounting portion 30 is disposed in the mounting groove 11 of the first mounting member 10, the cross section of the sealing portion 40 gradually decreases along the extending direction of the sealing portion 40 in the mounting portion 30 when the first mounting member 10 and the second mounting member 20 are assembled, so that the sealing portion 40 is elastically deformed when the second mounting member 20 presses the sealing portion 40 toward the first mounting member 10, thereby sealing the gap between the first mounting member 10 and the second mounting member 20.

Alternatively, the cross-sectional area of the hollow section of the sealing portion 40 gradually decreases along the extending direction of the mounting portion 30 to the sealing portion 40. In the above arrangement, when the first mounting member 10 and the second mounting member 20 are assembled, the second mounting member 20 presses the sealing portion 40 in the direction toward the first mounting member 10, and since the cross-sectional area of the hollow section of the sealing portion 40 gradually decreases in the extending direction from the mounting portion 30 to the sealing portion 40, the protrusions of the at least two sealing protrusions 41 of the sealing portion 40 are respectively abutted against at least part of the second mounting member 20, and thus the at least two sealing protrusions 41 of the sealing portion 40 are elastically deformed adaptively, and the hollow areas of the respective sealing protrusions 41 are pressed and blocked.

As shown in fig. 3 and 4, the hollow shape of the sealing part 40 is adapted to the outer shape of the sealing part 40; the seal portion 40 has a first seal side wall 42 and a second seal side wall 43 along the extending direction of the mounting portion 30 to the seal portion 40; wherein, along the extending direction from the mounting portion 30 to the sealing portion 40, the wall thickness of the first sealing sidewall 42 gradually increases; and/or the wall thickness of the second sealing sidewall 43 gradually increases along the extending direction of the mounting portion 30 to the sealing portion 40. In the above arrangement, the bottom ends of the at least two sealing protrusions 41 of the sealing portion 40 are respectively abutted against the edges of the opening of the mounting groove 11 of the first mounting member 10, the first sealing sidewall 42 and/or the second sealing sidewall 43 of the at least two sealing protrusions 41 are respectively connected with the bottom ends, and the wall thickness of the first sealing sidewall 42 and/or the second sealing sidewall 43 gradually increases along the extending direction from the mounting portion 30 to the sealing portion 40 and is respectively abutted against the second mounting member 20, that is, the wall thickness value of the abutting part of the protrusion of the sealing protrusion 41 and at least part of the second mounting member 20 is the largest, so that when the first mounting member 10 and the second mounting member 20 are assembled, the smaller wall thickness part of the first sealing sidewall 42 and the second sealing sidewall 43 is easier to elastically deform than other parts, so that the sealing portion 40 is adaptively deformed, and the gap between the first mounting member 10 and the second mounting member 20 is sealed, so as to prevent the leakage and outflow of the liquid from the battery compartment housing.

Further, at least two sealing projections 41 are connected, and a side wall of one of the at least two sealing projections 41 is connected with a side wall of the other of the at least two sealing projections 41 and encloses a sealing space 44; wherein, along the extending direction from the mounting portion 30 to the sealing portion 40, the sealing cross-sectional area of the sealing space 44 gradually increases; and/or the mounting portion 30 is connected to the junction of at least two sealing bumps 41. In the above arrangement, since the side wall of one of the at least two sealing projections 41 of the sealing portion 40 is connected with the side wall of the other of the at least two sealing projections 41 and encloses the sealing space 44, the liquid is prevented from flowing into the sealing space 44 from the abutment of the protrusions of the at least two sealing projections 41 with at least part of the second mounting member 20.

Specifically, one of the at least two sealing projections 41 is located at one side of the mounting groove 11, and the other of the at least two sealing projections 41 is located at the other side of the mounting groove 11; the bottom end of the sealing projection 41 is provided with a first sealing projection 45, the first sealing projection 45 projects from the bottom of the sealing projection 41, and the first sealing projection 45 is used for being attached to the notch edge of the mounting groove 11 of the first mounting component 10.

As shown in fig. 3, the mounting portion 30 is provided with a second sealing protrusion 31, the second sealing protrusion 31 protrudes outside the mounting portion 30, and the second sealing protrusion 31 is used for attaching to the groove wall of the mounting groove 11. In the above arrangement, the second seal projection 31 is brought into contact with the groove wall of the mounting groove 11, so that the mounting portion 30 receives a force from the extending direction of the seal portion 40 to the mounting portion 30 when the first mounting member 10 and the second mounting member 20 are assembled, and the mounting portion 30 is elastically deformed.

Further, at least two second sealing protrusions 31 are arranged on one side of the mounting portion 30 away from the sealing portion 40, and the at least two second sealing protrusions 31 are arranged at intervals; wherein at least two second sealing protrusions 31 are attached to the bottom wall of the mounting groove 11.

In the present embodiment, there are two second sealing protrusions 31, and the two second sealing protrusions 31 are respectively disposed on the outer side of the mounting portion 30 at intervals and respectively abut against the groove walls of the mounting groove 11.

It should be noted that the number of the second sealing protrusions 31 in the present embodiment is not limited to this, and may be selected according to the use requirement and the actual working condition, and alternatively, the second sealing protrusions 31 may be one, two, three, four, or more.

Alternatively, the wall thickness between two adjacent second sealing protrusions 31 is smaller than the wall thickness at the second sealing protrusions 31.

As shown in fig. 3 and 4, the mounting portion 30 is made of an elastic material, and the mounting portion 30 is of a hollow structure; the hollow section of the mounting portion 30 is gradually increased and then gradually decreased in the extending direction of the mounting portion 30 to the sealing portion 40. In the above arrangement, since the mounting portion 30 is made of an elastic material and has a hollow structure, the mounting portion 30 is elastically deformed and is fitted to the groove wall of the mounting groove 11 when sealing the gap between the first mounting member 10 and the second mounting member 20.

Specifically, the mounting groove 11 may be a wedge-shaped groove.

Alternatively, the wall thickness at the end portions of the mounting portion 30 is larger than the wall thickness at the middle portion of the mounting portion 30 in the extending direction of the mounting portion 30 to the sealing portion 40. Thus, since the wall thickness at the end portion of the mounting portion 30 is greater than the wall thickness at the middle portion of the mounting portion 30, that is, the portion at the middle portion of the mounting portion 30 is more easily elastically deformed than the portion at the end portion, so that when the first mounting member 10 is assembled with the second mounting member 20, after the portions at the end portion and the middle portion of the mounting portion 30 are pressed, the portion at the end portion is elastically deformed to be fitted with the groove wall of the mounting groove 11, and the portion at the middle portion is more elastically deformed to be fitted with the groove side wall of the mounting groove 11.

Specifically, the mounting portion 30 has a symmetrical structure, and the sealing portion 40 includes two sealing protrusions 41, and the two sealing protrusions 41 are symmetrically disposed along the symmetry axis of the mounting portion 30. Above-mentioned setting, seal structure is annular structure, and because installation department 30 is symmetrical structure, two sealing lug 41 set up along the symmetry axis symmetry of installation department 30 respectively to make when extrusion seal structure seals, seal structure can steadily take place adaptive elastic deformation, and then realize sealing the clearance between first installation component 10 and the second installation component 20.

In particular, the above arrangement enables a butterfly-shaped sealing structure to be formed. The highest point of the protrusion of the sealing protrusion 41 is offset from the highest point of the protrusion of the first sealing protrusion 45. With such a structural arrangement, it is possible to avoid the situation in which the highest point of the protrusion of the seal projection 41 and the highest point of the protrusion of the first seal projection 45 are on the same straight line, and thus the stress is large.

In the present embodiment, the value of the wall thickness at the convex portion of the seal bump 41 is 2cm to 5cm; the distance between the mounting part 30 and the sealing part 40 is 18.3cm to 22.3cm; the furthest distance between the two ends of the mounting part 30 takes a value of 8cm to 12cm; the furthest distance between the two sealing projections 41 takes a value of 23cm to 27cm; the distance between the part of the mounting portion 30 between the two second sealing protrusions 31 and the wall of the mounting groove 11 is 0.5cm to 1.5cm.

By applying the technical scheme of the utility model, the battery compartment comprises a compartment body 1 and a compartment door 2, wherein the compartment body 1 comprises one of a first mounting part 10 and a second mounting part 20; the door 2 comprises the other of the first mounting member 10 and the second mounting member 20; at least part of the above-mentioned sealing structure is located between the hatch 1 and the hatch 2. In this way, the gap between the first mounting member 10 and the second mounting member 20 is sealed by the sealing structure to avoid leakage of the liquid from the battery compartment.
