[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 3 and Figure 4As shown, in the present embodiment, a temperature monitoring device for charging a lithium battery comprises a battery housing 1, characterized in that: a mounting hole 2 is provided on one side of the battery housing 1, a monitor body 3 is placed inside the mounting hole 2, a same mounting assembly 4 is installed between the monitor body 3 and the mounting hole 2, the mounting assembly 4 comprises two mounting grooves 401 provided on both sides of the outer wall at one end of the monitor body 3, a movable rod 402 is slidably inserted into the inner wall of the side where the two mounting grooves 401 are close to each other, a limit card 403 is fixedly connected to the ends of the two movable rods 402 that are away from each other, and a spring 404 is sleeved on the two movable rods 402, and the two ends of the two springs 404 are respectively fixedly connected to the inner wall of the mounting groove 401 with one of the limit cards 403.

[0024] A limiting hole 405 is formed on the inner walls on both sides of the mounting hole 2 , and the two limiting clips 403 can enter the two limiting holes 405 respectively, and the length of the limiting hole 405 is greater than the length of the limiting clip 403 .

[0025] By pressing the two limit cards 403 at the same time, the spring 1 404 inside the installation slot 401 is squeezed and shortened, and the limit card 403 will also slide toward the inside of the installation slot 401 along with the movable rod 402. Then, the top end of the monitor body 3 is squeezed into the installation hole 2, and then the operation is repeated to make the monitor body 3 completely embedded in the installation hole 2. Finally, the restriction of the limit card 403 is released, and the compressed spring 1 404 will also restore its length. The two limit cards 403 will be pushed by the spring 1 404 to enter the two limit holes 405 respectively, and the position of the monitor body 3 will also be restricted.

[0026] like Figure 1 and Figure 3 As shown, an anti-vibration component 5 is installed on the top and bottom outer walls of the monitor body 3 , and the two anti-vibration components 5 are both located in the mounting hole 2 .

[0027] The anti-seismic component 5 includes two damping rods 501 fixedly installed on both sides of the top outer wall of the monitor body 3. The top outer walls of the two damping rods 501 are fixedly connected to the same connecting plate 502. A spring 2 503 is sleeved on the outside of the two damping rods 501.

[0028] When the battery is vibrated, the monitor body 3 will also move synchronously accordingly. The spring 2 503 between the monitor body 3 and the mounting hole 2 can reduce the amplitude of the vibration, and the damping rod 501 between the spring 2 503 can prevent the spring 2 503 from rebounding too violently. The vibration will also be gradually weakened, which can prevent the monitor body 3 from being damaged due to excessive vibration.

[0029] like Figure 3As shown, the outer walls of the ends of the two connecting plates 502 that are away from each other are both provided with anti-slip pads, which can increase the static friction between the connecting plates 502 and the mounting holes 2, and are beneficial to increasing the stability of the device.

[0030] like Figure 3 and Figure 4 As shown, the ends of the two limit cards 403 that are away from each other are both provided with rounded corners, so that the installation process of the monitor body 3 is easier to align and has a higher fault tolerance rate.

[0031] The utility model provides a temperature monitoring device for lithium battery charging, and the specific working principle is as follows:

[0032] When the device is working, the two limit cards 403 are pressed at the same time, and the spring 1 404 inside the mounting groove 401 is squeezed and shortened. The limit card 403 will also slide into the mounting groove 401 with the movable rod 402, and then the top end of the monitor body 3 is squeezed into the mounting hole 2, and then the operation is repeated to make the monitor body 3 completely embedded in the mounting hole 2, and finally the restriction of the limit card 403 is released, and the compressed spring 1 404 will also restore its length, and the two limit cards 403 will be pushed by the spring 1 404 to enter the two limit holes 405 respectively. At this time, the position of the monitor body 3 will also be restricted, and the battery is transported. When the battery is shaken, the monitor body 3 will also move synchronously accordingly, and the spring 2 503 between the monitor body 3 and the mounting hole 2 can reduce the amplitude of the vibration, and the damping rod 501 between the spring 2 503 can prevent the spring 2 503 from rebounding too violently, and the vibration will gradually be weakened, which can prevent the vibration from being too violent and causing damage to the monitor body 3.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
