DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment 1

[0034] In order to address the shortcomings of the existing technology, such as Figure 1-8As shown, the utility model provides a lithium battery device with a charging protection structure, including a lithium battery body 1, a charging port 2 and a charging plug 3, wherein the charging port 2 is provided with a fixing frame 21 and an upper fixing plate 22 and a lower fixing plate 23 for fixing the charging plug 3, wherein the upper fixing plate 22 and the lower fixing plate 23 are both provided with a connecting rod 24, wherein the connecting rod 24 is provided with an adjusting groove 1 241 and an adjusting groove 242 for controlling the opening and closing of the charging port 2, wherein both ends of the fixing frame 21 are provided with through grooves 211, wherein the through grooves 211 are used to install the connecting rod 24, wherein the through grooves 211 are provided with two groups of fixing grooves 212 along the inner side wall, wherein a clamping member 213 for limiting the position of the connecting rod 24 is provided in the fixing groove 212, wherein the clamping member 213 is composed of a ball, a base and a spring 2133, wherein the clamping member 213 is elastically connected to the inner wall of the fixing frame 21 through the spring 2133;

[0035] The upper fixing plate 22 and the lower fixing plate 23 are both provided with an arc groove for accommodating the wire body of the charging plug 3, and the arc groove forms a circular notch when the upper fixing plate 22 and the lower fixing plate 23 are closed. The engaging member 213 cooperates with the limiting adjustment groove 1 241 and the adjusting groove 242 provided on the connecting rod 24, so as to limit the extension and retraction of the connecting rod 24 in the through groove 211.

[0036] In summary, the basic working principle of the utility model is as follows: when the lithium battery needs to be charged, the upper fixing plate 22 is first slid upward. When the upper fixing plate 22 slides upward, the spring 2133 provided on the engaging piece 213 is forced to retract, so that the ball in the engaging piece 213 is disengaged from the notch of the adjusting groove 242. When the upper fixing plate 22 slides upward, when the adjusting groove 1 241 provided on the connecting rod 24 reaches the position of the engaging piece 213, the spring in the engaging piece 213 rebounds to make the ball embed in the adjusting groove 1 241, and limit the upper fixing plate 22, thereby achieving the effect of opening the upper fixing plate 22; then the lower fixing plate 23 is slid downward. When the lower fixing plate 23 slides downward, the spring 2133 provided on the engaging piece 213 is forced to retract, so that the ball in the engaging piece 213 is disengaged from the notch of the adjusting groove 1 241. When the lower fixing plate 23 slides downward, the adjusting groove 1 241 provided on the connecting rod 24 When the second groove 242 reaches the position of the engaging member 213, the spring rebound in the engaging member 213 causes the ball to be embedded in the second adjusting groove 242, and limits the lower fixing plate 23, thereby achieving the effect of opening the lower fixing plate 23. When the upper fixing plate 22 and the lower fixing plate 23 are both in the open state, the charging plug 3 is inserted into the charging port 2, and then the upper fixing plate 22 is slid downward, and then the lower fixing plate 23 is slid upward, so that the upper fixing plate 22 and the lower fixing plate 23 are closed, thereby fixing the charging plug 3 and preventing the charging plug from loosening due to touch during the charging process and stopping charging; when the upper fixing plate 22 and the lower fixing plate 23 are closed, the circular notch formed by the arc grooves opened on the upper fixing plate 22 and the lower fixing plate 23 is used to place the wire body of the charging plug 3, so that the charging plug 3 and the charging port 2 are in a relatively closed space, effectively preventing the safety hazards caused by water droplets splashing into the charging port.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
