Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, and in particular to a grid of a lead-acid battery. Background Technology

[0002] Lead-acid batteries are widely used in communications, energy storage, and power fields due to their excellent cost performance.

[0003] For example, the "A Spliced ​​Lead-Acid Battery Grid" published in CN215815946U includes a first spliced ​​battery grid and a second spliced ​​battery grid. A set of first splicing protrusions is symmetrically arranged above one end of the first spliced ​​battery grid, and a first through hole is opened on one side of the outer wall of the first splicing protrusion. A set of second splicing protrusions is symmetrically arranged above one end of the second spliced ​​battery grid, and a first rotating shaft block corresponding to the first through hole is provided on one side of the outer wall of the second splicing protrusion. The first spliced ​​battery grid and the second spliced ​​battery grid are connected by splicing. The structure is simple and easy to install. The grid can be folded after splicing.

[0004] While this patent allows for routine grid assembly, its flawed design in the assembly structure leads to a lack of restraints after assembly, causing the grid panels to easily detach during use and resulting in insufficient stability. Furthermore, when loading lead-acid batteries onto the grid panels, the frame can easily squeeze and deform the batteries, causing damage and compromising their protective capabilities. Therefore, we are introducing a new type of grid for lead-acid batteries. Utility Model Content

[0005] The main objective of this invention is to provide a grid for a lead-acid battery that can effectively solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A grid for a lead-acid battery includes four fixing bolts and eight electrode plates. Two partitions are fixedly connected to the left side of each electrode plate. The eight electrode plates are divided into two groups. Fastening devices are snapped onto the surfaces of the electrode plates in the two groups. A negative terminal is fixedly connected to the upper end of the left electrode plate, and a positive terminal is fixedly connected to the upper end of the right electrode plate. A bearing device is fixedly connected to the outer perimeter of the electrode plates. Connecting devices are fixedly connected to the four corners of the upper end of the bearing device through fixing bolts.

[0008] The fastening device includes a first side plate and a second side plate. The lower ends of the first side plate and the second side plate are fixedly connected to two fixing brackets. The end of the first side plate away from the fixing bracket has a second docking groove. A docking clip is inserted into the second docking groove. The two fixing brackets on the front side and the two fixing brackets on the rear side are fixedly connected to two connecting rods, and the two connecting rods are symmetrically distributed from left to right. The first side plate and the second side plate are located above the electrode plate.

[0009] Preferably, the supporting device includes a battery device, the upper front part and the upper rear part of the battery device are both provided with grooves, the lower wall of each groove is provided with a No. 1 docking groove, and the battery device is located on the outside of the electrode plate.

[0010] Preferably, the connecting device includes a battery cover, with mounting holes at the four corners of the upper end of the battery cover, and four terminal tubes inserted into the middle of the upper end of the battery cover. The outer surfaces of the four terminal tubes are fitted with sealing rings, and the inner walls of the terminal tubes are fixedly connected with anti-slip layers. The battery cover is fixedly installed on the upper end of the battery equipment by fixing bolts.

[0011] Preferably, the fixing bracket is snapped onto the upper end of the fastening device and the electrode plate, and the position and size of the docking clip are adapted to the position and size of the first docking groove.

[0012] Preferably, the four terminal cylinders are distributed laterally at equal intervals, the anti-slip layer covers the entire circumference of the inner wall of the terminal cylinder, and the length of the anti-slip layer is the same as the length of the effective connection portion of the inner wall of the terminal cylinder.

[0013] The above solution allows for the horizontal and equidistant distribution of terminal blocks, facilitating the uniform connection of external wires and ensuring balanced current conduction.

[0014] Preferably, the fixing bolt penetrates vertically through the connecting device and the bearing device, and the connection between the fixing bolt and the connecting device and the bearing device is provided with a threaded hole adapted to the fixing bolt.

[0015] The above solution, which combines vertical through-hole design with threaded holes, ensures a tight connection between the connecting device and the supporting device, thereby enhancing the overall structural strength of the battery.

[0016] Preferably, the groove is arranged along the length of the battery device, and the length of the groove is greater than the length of the plate group. Its width is adapted to the width of the fixing frame. The first docking groove is located at the center of the bottom of the groove, and the depth of the first docking groove matches the length of the docking clip insertion part.

[0017] The above solution ensures that the appropriate groove size allows the fastening device's mounting bracket to be precisely embedded, providing both positioning and support; the precise matching of the No. 1 docking slot and the docking clip ensures a stable connection between the fastening device and the load-bearing device, enhancing the electrode plate's fixing effect.

[0018] Preferably, the separator is arranged in parallel between two adjacent plates, and the height of the separator is the same as the height of the plate, and its length direction is the same as the length direction of the plate. The positive and negative terminals are located at both ends of the plate group, and the line connecting the centers of the positive and negative terminals is parallel to the length direction of the plate.

[0019] The above solution achieves a dimensional match between the separator and the electrode, effectively isolating adjacent electrode plates to prevent short circuits while ensuring the normal passage of electrolyte ions.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this utility model, through the unique design of the fastening device, the upper end of the electrode plate is clamped by the fixing bracket at the lower end of the first side plate and the second side plate, and the overall stability is enhanced by the connecting rod. The fastening device is also precisely connected to the first docking slot of the battery equipment in the carrier device through the docking clip, which ensures that the electrode plate remains stable during charging and discharging and avoids displacement. This greatly improves the stability and reliability of the grid structure and effectively prevents the battery performance from deteriorating or malfunctioning due to structural loosening.

[0022] In this utility model, through reasonable component layout and structural design, the battery equipment of the supporting device provides suitable supporting space for the plates, separators and fastening devices. The size design of the groove can ensure that the fixing frame is stably embedded without squeezing the plates and internal batteries. At the same time, the battery cover of the connecting device is firmly connected to the battery equipment through the fixing bolt, sealing and protecting the internal components. The sealing ring outside the terminal tube effectively isolates the external environment and prevents external factors from damaging the battery. This comprehensively enhances the protective performance of the lead-acid battery and avoids damage to the battery due to external factors. Attached Figure Description

[0032] Please see Figure 1-5 This utility model provides a technical solution:

[0033] A grid of a lead-acid battery includes fixing bolts 1 and plates 4. There are four fixing bolts 1 and eight plates 4. Two partitions 5 are fixedly connected to the left side of each plate 4. The eight plates 4 are divided into two groups. Fastening devices 7 are snapped onto the surface of the plates 4 in the two groups. A negative terminal post 8 is fixedly connected to the upper end of the left plate 4 and a positive terminal post 6 is fixedly connected to the upper end of the right plate 4. A bearing device 2 is fixedly connected to the outer perimeter of the plates 4. Connecting devices 3 are fixedly connected to the four corners of the upper end of the bearing device 2 through fixing bolts 1.

[0034] The fixing bolt 1 penetrates vertically through the connecting device 3 and the bearing device 2, and the connection between the fixing bolt 1 and the connecting device 3 and the bearing device 2 is provided with a threaded hole that is compatible with the fixing bolt 1.

[0035] The separator 5 is arranged in parallel between two adjacent plates 4, and the height of the separator 5 is the same as the height of the plate 4. Its length direction is the same as the length direction of the plate 4. The positive electrode post 6 and the negative electrode post 8 are located at the two ends of the plate 4 group, and the line connecting the centers of the positive electrode post 6 and the negative electrode post 8 is parallel to the length direction of the plate 4.

[0036] In this embodiment, the fastening device 7 includes a first side plate 71 and a second side plate 75. Two fixing brackets 74 are fixedly connected to the lower ends of both the first side plate 71 and the second side plate 75. A second docking groove 72 is formed at the end of the first side plate 71 away from the fixing brackets 74. A docking clip 73 is inserted into each of the second docking grooves 72. Two connecting rods 76 are fixedly connected to the two front fixing brackets 74 and the two rear fixing brackets 74, and the two connecting rods 76 are symmetrically distributed. The first side plate 71 and the second side plate 75 are located above the electrode plate 4. The supporting device 2 includes a battery device 21. The upper front and upper rear parts of the device have grooves 22, and the lower wall of each groove 22 has a first docking groove 23. The battery device 21 is located on the outside of the electrode plate 4. The fixing bracket 74 is snapped into the fastening device 7 and the upper end of the electrode plate 4. The position and size of the docking clip 73 are adapted to the position and size of the first docking groove 23. The groove 22 is set along the length of the battery device 21, and the length of the groove 22 is greater than the length of the electrode plate 4 group. Its width is adapted to the width of the fixing bracket 74. The first docking groove 23 is located at the center of the bottom of the groove 22, and the depth of the first docking groove 23 matches the length of the insertion part of the docking clip 73.

[0037] Through the above scheme: the fixing bracket 74 at the lower end of the first side plate 71 and the second side plate 75 in the fastening device 7 is snapped onto the upper end of the electrode plate 4 to achieve initial fixation of the electrode plate 4. The connecting rod 76 connects the front and rear fixing brackets 74 to enhance overall stability. The second docking groove 72 of the first side plate 71 cooperates with the docking clip 73. The docking clip 73 is then inserted into the first docking groove 23 at the bottom of the groove 22 of the battery device 21 in the carrier device 2, so that the fastening device 7 and the carrier device 2 are firmly connected, further fixing the electrode plate 4. At the same time, the length of the groove 22 is greater than that of the electrode plate 4 group and the width is adapted to the fixing bracket 74, which facilitates embedding and fixing. The precise size matching ensures the accuracy of installation. This design makes the electrode plate 4 stable during charging and discharging, avoiding displacement that affects the electrochemical reaction. The stable connection method enhances the structural strength of the battery and reduces the loosening of components caused by factors such as vibration.

[0038] In this embodiment, the connecting device 3 includes a battery cover 31. Mounting holes 32 are provided at the four corners of the upper end of the battery cover 31. Four terminal cylinders 34 are inserted and installed in the middle of the upper end of the battery cover 31. Sealing rings 33 are fitted onto the outer surfaces of the four terminal cylinders 34. Anti-slip layers 35 are fixedly connected to the inner walls of the terminal cylinders 34. The battery cover 31 is fixedly installed on the upper end of the battery device 21 by fixing bolts 1. The four terminal cylinders 34 are distributed laterally at equal intervals. The anti-slip layer 35 covers the entire circumference of the inner wall of the terminal cylinder 34, and the length of the anti-slip layer 35 is the same as the effective connection length of the inner wall of the terminal cylinder 34.

[0039] Through the above scheme: the battery cover 31 is fixedly connected to the battery device 21 by four fixing bolts 1 passing through the mounting holes 32 at the four corners of its upper end, enclosing the electrode plates 4, fastening devices 7 and other components inside the battery device 21, which plays a protective and fixing role. Four horizontally equidistant terminal tubes 34 are inserted and installed in the middle of the battery cover 31 to provide an interface for the battery to connect with the external circuit. The anti-slip layer 35 on its inner wall covers the entire circumference and is of appropriate length, increasing the friction with the external wires, ensuring the wire connection is firm, and ensuring stable current conduction. The sealing ring 33, which is sleeved on the outer surface of the terminal tube 34, surrounds the battery and is precisely positioned at the top and bottom, effectively isolating external air, moisture and impurities, preventing electrolyte leakage, and avoiding interference from the external environment to the internal electrochemical reaction of the battery.

[0040] It should be noted that this utility model relates to a grid for a lead-acid battery. During use, the electrode plates 4, as the core component, carry the active material and are the site of electrochemical reactions. The eight electrode plates 4 are divided into two groups. During charging and discharging, the active material on the electrode plates 4 undergoes an oxidation-reduction reaction with the electrolyte, realizing the mutual conversion of chemical energy and electrical energy. The positive terminal 6 and negative terminal 8 are respectively fixedly connected to the upper ends of the two groups of electrode plates 4, providing external electrical connection ports for the battery. In the circuit, current flows into or out of the electrode plates 4 through the positive terminal 6 and negative terminal 8, completing the transmission of electrical energy. The separator 5 is fixedly connected to the left side of the electrode plates 4, parallel to the two adjacent electrode plates 4, with its height consistent with the height of the electrode plates 4 and its length... With the same direction, the partition 5 prevents adjacent plates 4 from directly contacting and causing a short circuit, while allowing ions in the electrolyte to pass through, ensuring the normal progress of the electrochemical reaction. The first side plate 71 and the second side plate 75 of the fastening device 7 are located above the plates 4 and are snapped onto the upper end of the plates 4 by the fixing bracket 74, serving to fix and support the plates 4. The two connecting rods 76 connect the front and rear fixing brackets 74, enhancing the stability of the fastening device 7 and ensuring that the plates 4 will not shift during charging and discharging. The docking clip 73 is inserted into the second docking groove 72 of the first side plate 71, and its position and dimensions are aligned with the first docking groove 2 on the lower wall of the groove 22 of the battery device 21 in the bearing device 2. The three-phase compatibility ensures a stable connection between the fastening device 7 and the supporting device 2, further guaranteeing the fixation effect of the electrode plate 4. The battery device 21 of the supporting device 2 is located around the outer perimeter of the electrode plate 4, providing support space for the electrode plate 4, the separator 5, and the fastening device 7. The groove 22 is set along the length of the battery device 21, and its length is greater than the length of the electrode plate 4 group. Its width is adapted to the fixing frame 74, making it easy for the fixing frame 74 to be embedded in it. The first docking groove 23 is located at the center of the bottom of the groove 22, and its depth matches the length of the insertion part of the docking clip 73, achieving precise docking with the fastening device 7. The battery cover 31 of the connecting device 3 is fixedly installed on the upper end of the battery device 21 by four fixing bolts 1. The fixing bolts 1 are vertically... The connection is made through the battery cover 31 and the battery device 21, and the threaded hole at the connection point ensures the connection is firm. The four terminal tubes 34 on the battery cover 31 are distributed horizontally at equal intervals for connecting external wires to realize the connection between the battery and the external circuit. The sealing ring 33 surrounds the outer surface of the terminal tube 34, with the lower end abutting against the upper surface of the battery cover 31 and the upper end extending to the bottom of the terminal tube 34 port, effectively preventing electrolyte leakage and external impurities from entering the battery. The anti-slip layer 35 of the inner wall of the terminal tube 34 covers the entire circumference and has the same length as the effective connection part of the inner wall, which increases the friction between the wire and the terminal tube 34, ensuring a firm wire connection and ensuring the stability of current conduction.
