Description

Technical Field

[0001] The utility model belongs to the technical field of fault induction, in particular to a lithium battery fault induction indicator. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. During the production process of lithium batteries, the sensor indicator is connected to the internal circuit, and the sensor indicator mainly provides timely alarms for internal faults. Most of the current sensor indicators are integrated with lithium batteries, and their indicator lights are exposed. However, most of the indicators do not have a protective structure. When lithium batteries are transported, the sensor indicator is easily squeezed and damaged, resulting in the sensor indicator being unable to be used normally. Utility Model Content

[0003] In order to overcome the above defects, the utility model provides a lithium battery fault sensing indicator, which solves the problem that most indicators do not have a protective structure, and the sensing indicator is easily squeezed and damaged during the transportation of the lithium battery, resulting in the sensing indicator being unable to be used normally.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lithium battery fault sensing indicator, comprising a battery body, a rotating rod connected to the side of the battery body, a transparent protective plate overlapped on the side of the battery body, a sensor connected to the inside of the battery body, two connecting plates connected to the outside of the transparent protective plate, two mounting columns connected to the side of the battery body, a groove is provided in the connecting plate, a guide groove is provided in the connecting plate, an L-shaped plate is slidably connected in the guide groove, a threaded rod is rotatably connected in the guide groove, and the L-shaped plate is threadedly connected to the outside of the threaded rod.

[0005] As a further solution of the utility model: the installation column is clamped in the groove, and the L-shaped plate is clamped in the installation column.

[0006] As a further solution of the utility model: a convex groove is provided on the transparent protective plate, and a convex block is slidably connected in the convex groove.

[0007] As a further solution of the utility model: a sleeve plate is connected to the convex block, the rotating rod is rotatably connected inside the sleeve plate, and a push plate is connected outside the sleeve plate.

[0008] As a further solution of the utility model: a guide rod is connected inside the convex groove, and the convex block is slidably connected outside the guide rod.

[0009] As a further solution of the utility model: the guide rod is outer-mounted with a spring, and the convex block is connected in the convex groove through the spring.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The lithium battery fault sensing indicator is provided with a transparent protective plate, a connecting plate, a mounting column, a guide groove, an L-shaped plate and a threaded rod. When a rotational force is applied to the transparent protective plate, the plate will rotate around the rotating rod, and the mounting column on the side of the battery body will be interlaced with the groove. When the transparent protective plate is fitted with the battery body, the threaded rod is driven to rotate, and the L-shaped plate will slide on the surface of the threaded rod and then be snapped with the mounting column. The sensing indicator cooperates with the mounting column, the L-shaped plate and the threaded rod, so that the transparent protective plate and the battery body can achieve a quick positioning function, and the transparent protective plate can play a certain protective role on the sensor after being fixed, thereby avoiding the phenomenon that the sensor is squeezed and damaged during the transportation of the lithium battery, thereby ensuring the normal use of the sensing indicator.

[0012] 2. The lithium battery fault sensing indicator is provided with a convex block, a guide rod and a spring. When a thrust is applied to the sleeve plate, the convex block under the sleeve plate will slide in the convex groove, and the convex block will drive the spring to deform when sliding. When the sleeve plate loses resistance, it will be restored by the spring, so that the sleeve plate and the rotating rod can be quickly assembled, which is convenient for the subsequent replacement or maintenance of the transparent protective plate.

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-3As shown, the utility model provides a technical solution: a lithium battery fault sensing indicator, comprising a battery body 1, a rotating rod 2 is connected to the side of the battery body 1, a transparent protective plate 4 is overlapped on the side of the battery body 1, a sensor 3 is connected inside the battery body 1, two connecting plates 5 are connected outside the transparent protective plate 4, two mounting columns 6 are connected to the side of the battery body 1, and a groove 7 is opened in the connecting plate 5;

[0019] The mounting post 6 is clamped in the groove 7, and the L-shaped plate 11 is clamped in the mounting post 6. By providing the groove 7, when the transparent protective plate 4 is rotated and fitted with the battery body 1, the mounting post 6 on the surface of the battery body 1 will be inserted into the groove 7, so that the groove 7 plays a certain auxiliary role for the mounting post 6, avoiding collision between the mounting post 6 and the connecting plate 5;

[0020] A guide groove 10 is provided in the connecting plate 5, an L-shaped plate 11 is slidably connected in the guide groove 10, a threaded rod 12 is rotatably connected in the guide groove 10, the L-shaped plate 11 is threadedly connected to the outside of the threaded rod 12, a convex groove 13 is provided on the transparent protective plate 4, a convex block 14 is slidably connected in the convex groove 13, by providing the convex block 14, when a thrust is applied to the sleeve plate 8, the convex block 14 under the sleeve plate 8 will slide in the convex groove 13, so that the convex groove 13 plays a certain guiding role in the movement of the sleeve plate 8;

[0021] The convex block 14 is connected with a sleeve plate 8, the rotating rod 2 is rotatably connected in the sleeve plate 8, the sleeve plate 8 is externally connected with a push plate 9, and the convex groove 13 is connected with a guide rod 15. By setting a threaded rod 12, when a rotational force is applied to the threaded rod 12, the L-shaped plate 11 will move on the surface of the threaded rod 12, so that the L-shaped plate 11 can be clamped with the mounting column 6 after movement, and the threaded rod 12 can adjust the moving distance of the L-shaped plate 11;

[0022] The convex block 14 is slidably connected to the outside of the guide rod 15, and a spring 16 is connected to the outer outer surface of the guide rod 15. The convex block 14 is connected to the convex groove 13 through the spring 16. By setting the spring 16, when the convex block 14 moves, the spring 16 will be driven to deform, so that the spring 16 plays a certain supporting role for the convex block 14. When the convex block 14 loses resistance, it will be reset by the spring 16.

[0023] The working principle of the utility model is:

[0024] When the induction indicator is connected to the battery body 1, the push plate 9 applies a thrust to the sleeve plate 8, and the convex block 14 below the sleeve plate 8 slides in the convex groove 13. When the convex block 14 moves on the surface of the guide rod 15, the spring 16 is deformed. After the transparent protective plate 4 is placed under the battery body 1, the push plate 9 is released. When the sleeve plate 8 loses resistance, it is reset by the spring 16. After the reset, the sleeve plate 8 is clamped with the rotating rod 2.

[0025] When a rotational force is applied to the transparent protective plate 4, the transparent protective plate 4 will rotate around the rotating rod 2. When the transparent protective plate 4 rotates, the connecting plate 5 on the surface will fit with the battery body 1, and the mounting column 6 on the side of the battery body 1 will be inserted into the groove 7. When the transparent protective plate 4 fits with the battery body 1, it will drive the threaded rod 12 to rotate, and the L-shaped plate 11 will slide on the surface of the threaded rod 12. After sliding, the L-shaped plate 11 can be clamped with the mounting column 6, so that the transparent protective plate 4 and the battery body 1 can be fixed.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
