[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In the embodiment, Figures 1 - 5 there is provided a simple structure of a sealed projection welding nut, optionally but not limited to including: a bearing body 1;

[0029] A connecting ring 2 is provided on the outer side of the bearing body 1;

[0030] An installation groove 4 is opened on the upper surface of the bearing body 1;

[0031] An internal thread 5 is opened on the inner side of the installation groove 4;

[0032] A protection component 6 is rotatably provided in the installation groove 4 for protecting the internal thread 5.

[0033] In this embodiment, a simple structure of a sealed projection welding nut of the present invention is provided. By welding the connecting ring 2 to the battery box cover sheet metal weldment, and then through the internal thread 5 opened in the installation groove 4, the battery box cover sheet metal weldment can be installed by bolts. Moreover, since the internal thread 5 is opened in the installation groove 4 opened on the bearing body 1, the bearing body 1 can bear a large torque, making the installation of the battery box cover sheet metal weldment more stable. Then, through the protection component 6, it can be ensured that when welding the connecting ring 2, welding spatter is prevented from splashing into the installation groove 4 and damaging the internal thread 5, resulting in the inability to screw the bolt into the installation groove 4. And the bolt is screwed into the installation groove 4 to cooperate with the internal thread 5, so that after the sealed projection welding nut is welded to the battery box cover sheet metal weldment, the sealing performance of the battery box cover sheet metal weldment can be guaranteed.

[0034] Furthermore, the upper surface of the connecting ring 2 is flush with the upper surface of the bearing body 1, which can ensure that when welding the connecting ring 2, the upper surfaces of the connecting ring 2 and the bearing body 1 and the surface of the battery box cover sheet metal weldment can better contact, thus improving the use stability of the connecting ring 2 and the bearing body 1.

[0035] Further, as Figure 2 shown, the welding rib 3 is provided between the upper surfaces of the connecting ring 2 and the bearing body 1.

[0036] Furthermore, the welding rib 3 is an annular welding rib, and the cross-section of the welding rib 3 is conical; at the same time, the size of the welding rib 3 can be adjusted accordingly according to the requirements of the welded parts, the material thickness and the process parameters of the welding equipment.

[0037] In this embodiment, multiple preferred embodiments of the welding rib 3 are given. Through the welding rib 3, the connecting ring 2 is welded to the sheet metal weldment of the battery box cover, and through the annular welding rib 3, after welding the connecting ring 2, it can be ensured that the connecting ring 2 can be melted and integrated with the sheet metal weldment of the battery box cover to meet the requirements of torque and sealing.

[0038] Further, as Figure 4 shown, the protection component 6 in the preferred embodiment of the present utility model includes a protection block 61 rotatably provided inside the installation groove 4; an external thread 62 provided on the outer side of the protection block 61; and a rotating block 63 provided on the outer side of the protection block 61.

[0039] Furthermore, the external thread 62 provided on the outer side of the protection block 61 is adapted to the internal thread 5 provided in the installation groove 4.

[0040] Furthermore, the outer sides of both the protection block 61 and the rotating block 63 are coated with anti-spatter agent, so as to avoid welding spatter adhering to the outer sides of the protection block 61 and the rotating block 63, resulting in the inability to remove the protection block 61 from the installation groove 4.

[0041] In this embodiment, multiple preferred embodiments of the protection component 6 are given. By rotating the rotating block 63, the protection block 61 is screwed into the installation groove 4, and the external thread 62 on the outer side of the rotating block 63 is threadedly connected to the internal thread 5 provided in the installation groove 4, so that when the connecting ring 2 is welded, the protection block 61 will not slide out of the installation groove 4, so that the protection block 61 can block the welding spatter and avoid the welding spatter from splashing into the installation groove 4 and causing damage to the internal thread 5 provided in the installation groove 4. In addition, the outer sides of both the protection block 61 and the rotating block 63 are coated with anti-spatter agent, so as to avoid welding spatter adhering to the outer sides of the protection block 61 and the rotating block 63, resulting in the inability to remove the protection block 61 from the installation groove 4.
