Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4

[0025] A battery plate fixing mechanism for new energy vehicles, used in lead-acid batteries for automobiles, serves as a core component of the automotive battery system, bearing the crucial responsibility of ensuring stable and reliable battery performance. The mechanism mainly consists of two parts: a positive electrode substrate group 1 and a negative electrode plate group 2. The positive electrode substrate group 1 comprises multiple tightly stacked positive lead plates 11, arranged according to specific process requirements to ensure uniform current distribution and efficient current transmission. The negative electrode plate group 2 also consists of multiple stacked negative lead plates 21, whose materials and specifications are rigorously selected to meet the battery's operating environment and performance requirements. The positive and negative lead plates 11 and 21 are arranged in a staggered, parallel configuration on one side; this unique arrangement not only optimizes the internal electric field distribution of the battery but also improves its energy density and charge / discharge efficiency. On the upper side of both the positive lead plate 11 and the negative lead plate 21, there are cleverly arranged contact pieces 3. These contact pieces 3 serve as key nodes for current transmission, and their material and shape are carefully designed to ensure good conductivity and mechanical strength.

[0026] Between the negative lead plate 21 and the positive lead plate 11, a negative lead guard plate 22 and a positive lead plate separator 12 are arranged. The main function of the negative lead guard plate 22 is to prevent short circuits between the negative lead plates 21, and at the same time, it guides the flow of electrolyte inside the battery. The positive lead plate separator 12 further refines the internal spatial structure of the battery, effectively isolating the positive lead plate 11 and avoiding direct contact between the positive and negative electrodes, thereby ensuring the safe operation of the battery. A positive lead guard plate 13 is provided on the outside of the positive lead plate 11. The positive lead guard plate 13 not only protects the positive lead plate 11, but also enhances the overall structural stability of the battery. The negative lead guard plate 22 is provided with corresponding contacts 3 to the negative lead plate 21. These contacts 3, together with the contacts 3 on the negative lead plate 21, constitute the current transmission network of the negative electrode. Similarly, the positive lead plate separator 12 and the positive lead plate 13 are also provided with contact pieces 3 corresponding to the positive lead plate 11 to ensure stable transmission of positive current.

[0027] The positive electrode lead plate 11, the positive electrode lead plate separator 12, and the positive electrode lead guard plate 13 are fixedly connected to the positive electrode connection terminal 5 through a specific connection method. The positive electrode connection terminal 5 is a key component for connecting the battery to the external circuit, and its structural design directly affects the battery's performance and safety. The positive electrode connection terminal 5 includes a positive terminal body 51, which serves as the main structure of the connection terminal and has good mechanical strength and conductivity. A positive electrode connecting piece 52 is provided on the upper part of the positive terminal body 51. The shape and size of the positive electrode connecting piece 52 are precisely calculated to ensure a reliable connection with external wires. Positive electrode welding pieces 53 are evenly arranged on the lower part of the positive terminal body 51. The number and position of the positive electrode welding pieces 53 correspond one-to-one with the connecting pieces 3 on the positive electrode lead plate 11, the positive electrode lead plate separator 12, and the positive electrode lead guard plate 13, and a firm connection is achieved through a welding process.

[0028] Negative electrode connection terminals 6 are fixedly connected to the tabs 3 on the negative electrode lead plate 21 and negative electrode lead guard plate 22. The structure of the negative electrode connection terminal 6 is similar to that of the positive electrode connection terminal 5, but it is optimized according to the working characteristics of the negative electrode. The negative electrode connection terminal 6 includes a negative electrode body 61, which also has good mechanical and electrical properties. A negative electrode connection post 62 is provided on the upper part of the negative electrode body 61. The design of the negative electrode connection post 62 facilitates connection with external circuits and can withstand certain mechanical stress and current surges. Negative electrode contact welding tabs 63 are evenly arranged on the lower part of the negative electrode body 61. The negative electrode contact welding tabs 63 are tightly connected to the tabs 3 on the negative electrode lead plate 21 and negative electrode lead guard plate 22 through a welding process to ensure stable transmission of negative electrode current.

[0029] The positive electrode lead separator 13 and the negative electrode lead separator 22 are uniformly mesh-like. This mesh structure has many advantages. On the one hand, the mesh structure increases the electrolyte flow area, promotes the uniform distribution of electrolyte inside the battery, and improves the battery's charge and discharge performance. On the other hand, the mesh structure also reduces the weight of the separator, lowering the overall weight of the battery, while ensuring sufficient mechanical strength. The positive electrode lead separator 12 has uniformly arranged holes. The size and distribution of these holes are carefully designed to ensure smooth electrolyte passage while effectively preventing direct contact between the positive and negative electrode lead plates, thus providing good isolation.

[0030] The positive electrode lead plate separator 12, the positive electrode lead guard plate 13, and the negative electrode lead guard plate 22 are all insulating plates. The use of insulating plates is one of the key measures to ensure battery safety. These insulating plates have good insulation properties, effectively preventing short circuits between the positive and negative electrodes and avoiding dangerous situations such as overheating, fire, or even explosion during battery charging and discharging. At the same time, the insulating plates also have a certain degree of corrosion resistance, enabling them to adapt to the complex chemical environment inside the battery and extending its service life.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
