Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a lithium battery with a protective shell. Background Art

[0002] Lithium batteries are primary batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They are different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The disadvantage of existing lithium batteries is that they are prone to expansion, damage, and even explosion. There are many reasons for lithium battery explosions.

[0003] According to a publicly disclosed lithium battery casing with a protective structure (Announcement No.: CN112838311A), the connection between the two sets of protective shells in the above application is installed by bolts. During the installation process, it is necessary to manually keep the two sets of protective shells aligned. The long-term manual alignment operation is very likely to cause displacement due to hand shaking. The offset protective shell will affect the subsequent installation process. To address this problem, we have proposed a lithium battery with a protective shell. Utility Model Content

DETAILED DESCRIPTION

[0020] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a lithium battery with a protective shell, comprising a lithium battery body 1, a lower protective shell 2 and an upper protective shell 5, the surface of the lower protective shell 2 is provided with a heat dissipation hole 3, the surface of the lower protective shell 2 is provided with a through hole 4, the surface of the upper protective shell 5 is fixedly installed with a connecting block 6, and a control component 7 for preliminary positioning is provided in the connecting block 6.

[0021] The control component 7 includes: a positioning block 71, a rotating rod 72 is fixedly installed on the surface of the positioning block 71, the rotating rod 72 passes through the connecting block 6 and is rotatably connected to the connecting block 6, an annular groove 73 is provided on the surface of the rotating rod 72, and the sliding rod 74 is slidably connected to the surface of the annular groove 73, and a support rod 75 is fixedly installed on the surface of the sliding rod 74. When the support rod 75 fixed on the surface of the slide plate 761 drives the sliding rod 74 to slide in the annular groove 73 provided on the surface of the rotating rod 72, when the sliding rod 74 moves, the rotating rod 72 can be subjected to force to drive the positioning block 71 to rotate. The rotated positioning block 71 can form an interlaced shape with the through hole 4, thereby completing the preliminary positioning between the upper protective shell 5 and the lower protective shell 2 to facilitate subsequent connection.

[0022] The control assembly 7 also includes a rotating member 76, which includes a slide 761. The surface of the slide 761 is fixedly connected to the surface of the support rod 75. The slide 761 passes through a circular ring 762 and is slidably connected to the circular ring 762. The circular ring 762 is fixedly mounted on the inner wall of the connecting block 6. When the slide 761 moves, the slide rod 74 can move synchronously. A protrusion 763 is fixedly mounted on the surface of the slide 761. The protrusion 763 passes through a circular disk 765 and is slidably connected to the circular disk 765. The circular disk 765 is rotatably connected to the surface of the circular ring 762. The surface of the circular disk 765 has an arc hole 764. The inner wall of the arc hole 764 is in contact with the surface of the protrusion 763. When the circular disk 765 rotates, the arc hole 764 can contact the protrusion 763, and the slide 761 fixed to the surface of the protrusion 763 can slide longitudinally. A support block 766 is fixedly mounted on the surface of the disk 765. The support block 766 is penetrated by a clamping rod 767 and is slidably connected to the clamping rod 767. The surface of the clamping rod 767 is fixedly connected to one end of a spring 768, the other end of which is fixedly mounted on the surface of the support block 766. A support block 769 is fixedly mounted on the surface of the clamping rod 767. The clamping rod 767 can move longitudinally within the support block 766 supported by the spring 768. A snap ring 7610 is fixedly mounted on the surface of the connecting block 6. The inner wall of the snap ring 7610 is rotatably connected to the disk 765, allowing the disk 765 to perform circular motion within the snap ring 7610. A circular groove 7611 is formed on the surface of the snap ring 7610, and a clamping groove 7612 is formed on the surface of the snap ring 7610. The provision of the clamping groove 7612 restricts the rotation of the clamping rod 767 and the disk 765.

[0023] In the present invention, when the lithium battery body 1 needs to be protected during use, the lithium battery body 1 is placed in the lower protective shell 2, and then the upper protective shell 5 is fitted with the lower protective shell 2. After fitting, the support block 769 is used to pull the card rod 767 to slide in the support block 766 under the support of the spring 768. When the card rod 767 is removed from the card slot 7612, the pulling force is maintained, and the support block 766 is used to drive the disk 765 to rotate. When the disk 765 rotates, the arc hole 764 opened on the surface of the disk 765 contacts the surface of the protrusion 763. The protrusion 763 is forced to drive the slide plate 761 to slide in the ring 762. The slide plate 76 When the slider 761 moves, the support rod 75 fixed on the surface of the sliding plate 761 drives the sliding rod 74 to slide in the annular groove 73 provided on the surface of the rotating rod 72. When the sliding rod 74 moves, the rotating rod 72 can be forced to drive the positioning block 71 to rotate. The rotated positioning block 71 can form a staggered shape with the through hole 4, thereby completing the preliminary positioning between the upper protective shell 5 and the lower protective shell 2 for subsequent connection. After the preliminary connection, the operator can connect and fix the upper protective shell 5 and the lower protective shell 2 with bolts, and the heat dissipation holes 3 provided on the surface of the lower protective shell 2 can facilitate the lithium battery body 1 to discharge the heat generated by the lithium battery body 1 during use.

[0024] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
