Description

Technical Field

[0001] The invention relates to the technical field of battery grid structures, in particular to a grid structure with lockable edges. Background Art

[0002] The grid is the main component of the battery. Its functions in the battery are: 1. Supporting the active material; 2. Evenly distributing the current on the active material to improve the utilization rate of the active material. There are two traditional methods for manufacturing grids: drawing and casting. Casting is to pour the heated and molten lead alloy into the grid mold under the action of gravity, and then cool it to form, and then process it; drawing is to make a specified rectangular hole on a lead strip of a certain width on a punch, and then stretch it to form it.

[0003] The grid manufactured by the above method has a large weight and poor corrosion resistance to sulfuric acid, resulting in a short battery life, and the lead causes serious environmental pollution, so the country will gradually eliminate it. In order to reduce the weight of the grid and reduce lead pollution, a composite mesh battery has been developed, which uses a composite wire made of carbon fiber coaxial composite zinc wire or carbon fiber coaxial composite graphene to weave a mesh as a grid. It is not only light in weight and meets environmental protection requirements, but also extends the service life of the battery. When manufacturing this woven mesh grid, it is generally woven into a relatively wide grid belt, and then cut into a grid belt that meets the width requirements according to requirements, which makes it easy to separate the warp and weft at the edge of the grid belt, reducing the effective area of ​​the grid, thereby affecting the use of the grid. In the prior art, a hot melt wire is woven into the edge of the grid, and the melting and bonding effect of the hot melt wire is used to prevent the separation of the warp and weft at the edge of the grid, thereby achieving the effect of locking the edge. However, since the hot melt wire needs to be heated during hot melting, the edge of the grid is also affected by the heat, causing the middle and edge of the grid to be heated unevenly, which can easily affect the structural stability of the grid. Summary of the invention

[0004] The present invention is intended to provide a lockable edge grid structure to solve the problem in the prior art that the grid is easily subjected to uneven heating during edge locking, resulting in poor edge locking effect.

[0005] The basic scheme of the present invention is: a lockable grid structure, including a grid body, the grid body including warp and weft, the warp and weft are cross-arranged, the edge of the grid body is provided with a clamping strip, the clamping strip is arranged in a direction parallel to the warp, the clamping strip includes a first side plate, a second side plate and a vertical plate, the vertical plate is located on the outside of the grid body, the first side plate and the second side plate are respectively located on both sides of the grid body and are flexibly connected to the vertical plate, the first side plate and the second side plate are flexibly connected at one end away from the vertical plate with a baffle facing the grid body; the end of the weft at the edge of the grid body bypasses the warp at the edge of the grid body and abuts against the baffle.

[0006] Compared with the prior art, the advantages of this solution are: by setting the first side plate and the second side plate, the first side plate and the second side plate restrict the bent end of the weft line, so as to prevent the bent end of the weft line from swinging at will. By setting the baffle plate and the vertical plate, the bent end of the weft line is located between the baffle plate and the vertical plate, and the bent end of the weft line can abut against the baffle plate, thereby preventing the weft line from slipping out of the clamping strip. After the weft line passes around the warp line at the edge of the grid, the bent end of the weft line surrounds the warp line, so that the warp line and the weft line at the edge of the grid will not be separated, and at the same time, with the effect of the clamping strip, the edge of the grid is locked.

[0007] Furthermore, the first side panel, the second side panel and the vertical panel are integrally formed. By integrally forming, the overall shape of the first side panel, the second side panel and the vertical panel is better. Meanwhile, in actual production, since the sizes of the first side panel, the second side panel and the vertical panel are relatively small, it would be inconvenient to operate if they are connected later.

[0008] Furthermore, the baffle is arranged to be inclined toward the inner side of the clamping strip. By arranging the baffle to be inclined, the baffle can play a guiding role when the weft thread is inserted into the clamping strip, thereby facilitating the insertion of the weft thread into the clamping strip and facilitating the operation.

[0009] Furthermore, the baffle is provided with a slot corresponding to the weft line. By providing the slot, the weft line is stuck in the slot, so that the baffle can push the weft line to move when it moves.

[0010] Furthermore, the card slot of the baffle connected to the first side panel stores the original glue in the AB glue component, and the card slot of the baffle connected to the second side panel stores the hardener in the AB glue component. When the weft is inserted into the card slot of the baffle on the first side panel, the original glue in the card slot will be coated on the weft; when the weft is inserted into the card slot of the baffle on the second side panel, the hardener in the card slot will be coated on the weft, so that the original glue and the hardener of the AB glue component are mixed, making the weft sticky, so as to stick the baffles on both sides of the weft, and enhance the connection between the card strip and the weft.

[0011] Furthermore, the cross section of the vertical plate is in an arc shape, so that the bent portion of the ends of the weft lines can abut against the vertical plate, thereby increasing the contact area. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The embodiment is basically as shown in the attached Figure 1 , Figure 2 and Figure 3 As shown: a lockable grid structure includes a grid body, the grid body includes a warp 2 and a weft 3, and the warp 2 and the weft 3 are cross-woven. A clip 1 is provided at the edge of the grid body, and the clip 1 is arranged in a direction parallel to the warp 2. The clip 1 includes a first side plate 5, a second side plate 6 and a vertical plate 4, the first side plate 5 and the second side plate 6 are integrally formed with the vertical plate 4, and a notch is provided on the inner side of the intersection of the first side plate 5 and the vertical plate 4. The notch is provided so that the intersection of the first side plate 5 and the vertical plate 4 forms stress concentration due to the reduction of the cross-sectional area, which facilitates the deformation of the first side plate 5 when swinging; a notch is also provided at the intersection of the second side plate 6 and the vertical plate 4; the cross section of the vertical plate 4 is in an arc shape, the vertical plate 4 is located on the outside of the grid body, the first side plate 5 is located on the upper side of the grid body, and the second side plate 6 is located on the lower side of the grid body, so that the first side plate 5, the second side plate 6 and the vertical plate 4 surround the edge of the grid body on three sides. A first baffle 7 is provided at one end of the first side plate 5 away from the vertical plate 4, and the upper end of the first baffle 7 is flexibly connected to the first side plate 5. The lower end of the first baffle 7 is arranged in the direction of the vertical plate 4, and a first card slot 71 opposite to the weft line 3 is provided at the lower part of the first baffle 7, and the first card slot 71 stores the original glue in the AB glue component. A second baffle 8 is provided at one end of the second side plate 6 away from the vertical plate 4, and the lower end of the second baffle 8 is flexibly connected to the second side plate 6. The upper end of the second baffle 8 is arranged in the direction of the vertical plate 4, and a second card slot 81 opposite to the weft line 3 is provided at the upper part of the second baffle 8, and the hardener in the AB glue component is stored in the second card slot 81. The first baffle 7 and the second baffle 8 are bonded to the weft line 3 by AB glue, and the end of the weft line 3 bends upward around the warp line 2 at the edge of the grid and extends laterally to abut against the first baffle 7.

[0019] The specific implementation process is as follows: Before using the card strip 1, Figure 4As shown, the distance from the right end of the first side plate 5 to the grid body is greater than the distance from the left end of the first side plate 5 to the grid body, the distance from the right end of the second side plate 6 to the grid body is greater than the distance from the left end of the second side plate 6 to the grid body, the first baffle plate 7 is in a state of being inclined at the lower end toward the vertical plate 4, the second baffle plate 8 is in a state of being inclined at the upper end toward the vertical plate 4, the first card groove 71 stores the original glue in the AB glue component, and the second card groove 81 stores the hardener in the AB glue component; the end of the weft line 3 is in a bent state and the bent position is against the vertical plate 4. When locking the grid body, the first side plate 5 and the second side plate 6 are brought closer to each other by applying pressure, and the first side plate 5 swings around the intersection with the vertical plate 4. When the first side plate 5 swings, the first baffle plate 7 moves toward the weft line 3, so that the weft line 3 is clamped into the first clamping groove 71; at the same time, when the second side plate 6 swings, it also drives the second baffle plate 8 to move toward the weft line 3, so that the weft line 3 is clamped into the second clamping groove 81. Therefore, the weft line 3 moves toward the vertical plate 4 under the clamping action of the first clamping groove 71 and the second clamping groove 81. Therefore, the weft line 3 is guided by the vertical plate 4. A certain deformation causes the end of the weft line 3 to extend toward the first baffle plate 7, so that the end of the weft line 3 is abutted against the first baffle plate 7; as the first baffle plate 7 and the second baffle plate 8 continue to move, the first baffle plate 7 and the second baffle plate 8 are deformed after abutting against each other, so that more parts of the weft line 3 are stuck in the first slot 71 and the second slot 81, so that the glue in the first slot 71 and the hardener in the second slot 81 are both coated on the weft line 3, so that the glue and the hardener are mixed, and finally the first baffle plate 7 and the second baffle 8 are bonded to the weft line 3, completing the locking operation of the grid body.
