[0002] Battery fixtures are a complex and important field. Small battery systems integrate multiple battery cells in a sturdy plastic frame, and achieve smooth energy flow through the lead-out of positive and negative electrodes. It is particularly worth mentioning that advanced laser welding technology is used between the aluminum bar or copper busbar and the battery cell to ensure that the connection point is firm and gapless, which not only improves the stability of the overall structure, but also ensures the efficiency and safety of current transmission. In current production, welding small batteries faces challenges, mainly due to the lack of suitable tooling and fixtures. This makes it difficult to accurately align the battery cell and the battery aluminum bar due to dimensional tolerances during welding, and frequent manual intervention and adjustment are required, which not only reduces the quality of battery assembly, but also seriously restricts production efficiency. In addition, the lack of downward pressure during welding causes the aluminum bar to shift in position and the penetration depth to be insufficient, which has a significant impact on the welding quality.

[0020] The technical solution of the present invention is further described below in detail through specific embodiments and in combination with the accompanying drawings. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figures 1 to 5, a battery clamp includes a base 2, which has an I-shaped structure as a whole. The edge of the base 2 is provided with a stepped structure, which makes the base 2 not easy to tip over. Two side panels 3 are distributed on both sides of the base 2, and the side panels 3 are connected to the base 2 for fixing with the top cover 7. The top of the side panels 3 is connected to the top cover 7. In order to make it possible to tighten, a tightening knob 6 for tightening is provided above the top cover 7. The tightening knob 6 is provided with a concave and convex shape around it, so that when tightening, the friction is greater, thereby providing better fine control. A lower positioning plate 9 is also provided on the base 2, and the lower positioning plate 9 is stuck in the base 2. An upper positioning plate 4 is also fixed to the lower side of the top cover 7, and the top cover 7 is fixed to the upper positioning plate 4 by a tightening member 10. The shape of the entire base is designed to be I-shaped to enhance its stability and load-bearing capacity.

[0022] It should be noted that in the design of this battery clamp, a plurality of top cover openings 8 are distributed on the top cover 7. A pressing member 10 is provided below the top cover opening 8. The pressing member 10 directly contacts the top of the upper positioning plate 4, playing a role of leveraging. The pressing member 10 can be selected from some elastic objects, such as springs. The compression will make the force distribution more uniform during compression, and the use of springs also forms an effective air circulation channel inside the clamp. This design helps to discharge the heat during battery welding in a timely manner, thereby keeping the battery within a suitable temperature range.

[0023] It should be noted that side connecting posts 11 are installed above side panels 3. These posts 11 connect and secure side panels 4 to top cover 7. Passing through top cover fixing holes 5 in top cover 7, they provide a more secure connection between the two panels, enhancing the rigidity and durability of the entire fixture. The use of these posts in conjunction with top cover fixing holes 5 also makes assembly and disassembly of the fixture more convenient and quick.

[0024] It should be noted that the clamping knob 6 can be screwed into the side connecting column 11, and the top cover 7 can be tightened by rotating. This clamping mechanism is not only simple and easy to use, but also can provide a uniform and stable clamping force to ensure that the battery is firmly fixed in the fixture to prevent displacement or falling off during operation. The design of the clamping knob 6 can prevent the battery from causing short circuits or other safety hazards due to looseness during welding or other operations. The combination of the top cover opening 8, the side connecting column 11 and the clamping knob 6 makes the entire fixture more structurally stable. Base fixing holes 1 are also provided around the base 2. These fixing holes can be used to fix the battery clamp on a workbench or other appropriate location for easy operation and use.

[0025] It should also be noted that the base 2 of this embodiment is made of brown flame-retardant material through CNC machining. Four base fixing holes 1 are provided around the base 2 for fixing, and the middle area is hollowed out to reduce weight and facilitate handling. In addition, there is a side panel 3 extending vertically upward on each side of the base 2. The top cover 7 is made of the same material as the base 2 and is also a CNC-machined overall rectangular structure. On one side, the approximate contour of the battery welding surface 5 is milled to secure the battery, and holes are opened according to the location of the welding points to install the clamping member 10.

[0026] The specific working steps of this embodiment are as follows: First, place the base 2 on the laser welding table. The base 2 is designed to sit securely on the table. Its I-shaped structure and stepped edges provide additional stability, preventing the battery from moving or vibrating during the welding process. The bottom of the base 2 includes a non-slip pad or fixing clip to further ensure its stability on the table. Next, precisely position the battery within the lower positioning plate 9 above the base 2. The positioning holes 92 on the lower positioning plate 9 are designed to match the battery's dimensions, ensuring accurate placement in the intended location. After the battery is positioned, align the battery's welding points with the bolt holes on the base 2, and then place the upper positioning plate 4 and top cover 7. The reinforced edge grooves 42 and reinforcement bars 41 on the upper positioning plate 4 help ensure stability during the clamping process. Furthermore, the positioning holes in the upper positioning plate 4 should align with those in the lower positioning plate 9 to precisely secure the battery. The final step is to install and rotate the clamping knob 6. The clamping knob 6, through its internal nut, engages with the bolts on the base 2, providing downward pressure on the top cover 7. This clamping mechanism ensures that the top cover 7 firmly presses the battery against the battery, preventing it from shifting during welding. The clamping member 10, typically an elastic member such as a spring, is located below the top cover 7. It evenly transfers the pressure of the top cover 7 to the battery, ensuring uniform pressure at the welding point, thereby achieving a high-quality weld.

[0027] Example 2: Reference Figures 1 to 5The main structure of this embodiment is similar to that of embodiment 1. On the basis of embodiment 1, some improvements and restrictions are made to the interior of the upper positioning plate 4 and the lower positioning plate 9. This embodiment is described in detail below. The design of the battery clamp of this embodiment includes the following main parts: base 2, side plate 3, top cover 7, clamping knob 6, lower positioning plate 9, upper positioning plate 4, clamping member 10, top cover opening 8, side connecting column 11 and base fixing hole 1. The base 2 is made of brown flame retardant material, and the stepped design of the base edge prevents it from tipping over during operation. The side plates 3 are fixed to both sides of the base and connected to the top cover 7 through the side connecting column 11. There are multiple top cover openings 8 on the top cover 7. These openings allow hot air to be discharged during operation, keeping the battery working at a suitable temperature and making it safer during welding. The clamping member 10 is located below the top cover opening 8 and directly contacts the upper positioning plate 4, playing a role of leveraging. The clamping member 10 can be an elastic object, such as a spring, to achieve uniform force and promote air circulation.

[0028] It should be noted that the clamping knob 6 is designed with a concave and convex surface to increase the friction when tightening and achieve fine control. It can be screwed into the side connecting column 11 and tighten the top cover 7 through the rotation action to ensure that the battery is firmly fixed and prevent displacement or falling off during operation, thereby improving the safety of operation. The side connecting column 11 passes through the top cover fixing hole 5 on the top cover 7, making the connection between the side panel 3 and the top cover 7 more stable. The base 2 is surrounded by base fixing holes 1, which can be used to fix the clamp on a workbench or other appropriate positions. The middle area of ​​the base 2 is hollowed out to reduce weight and facilitate carrying. The side panel 3 extends vertically upward from the base 2. The material of the top cover 7 is consistent with that of the base 2. It is also an overall rectangular structure processed by CNC. One side is milled according to the contour of the battery welding surface to fix the battery, and holes are opened according to the position of the welding point to install the clamp 10.

[0029] It should be noted that in the battery clamp of this embodiment, the upper positioning plate 4 is provided with reinforcing side grooves 42 on its sides, which is a notable feature of the upper positioning plate 4's design. These side grooves are recessed and integrated into the structure of the upper positioning plate 4, enhancing the plate's overall rigidity and making it less susceptible to deformation when subjected to pressure. The design of the reinforcing side grooves 42 enhances the structural strength of the upper positioning plate 4 and can disperse and transmit various forces acting on the plate during operation. During use of the battery clamp, the upper positioning plate 4 is required to withstand pressure from the clamping member 10. The reinforcing side grooves 42 can effectively disperse this pressure over a wider area, reducing local stress concentration and thereby extending the service life of the upper positioning plate 4. The upper positioning plate 4 takes into account its positioning accuracy in the clamp. The presence of the reinforcing side grooves 42 provides the upper positioning plate 4 with additional support points, ensuring that the upper positioning plate 4 is accurately placed on the top cover 7. During long-term use, the upper positioning plate 4 is inevitably subjected to repeated loads and pressure.

[0030] It should be noted that reinforcing strips 41 are installed above the upper positioning plate 4. These strips extend across the entire surface of the upper positioning plate 4, providing additional support and stability to the clamp's structure. The design of the reinforcing strips 41, combined with the structural frame in which the batteries are placed, creates a frame-like shape, significantly enhancing the clamp's overall strength. Specifically, these reinforcing strips 41 are formed into four L-shaped shapes, forming a sturdy support network. The L-shaped structure distributes the compressive force applied to the batteries. Each L-shaped reinforcing strip intersects the upper positioning plate 4 at a specific angle, forming a stable support point that securely holds the batteries in the clamp and prevents any displacement or slippage during operation. This design is crucial for maintaining battery stability during welding and other operations, effectively preventing accidental disengagement due to vibration or external impact. The presence of the reinforcing strips 41 also prevents misalignment of the clamping member 10 when applying pressure. This is because the framework structure of these reinforcing strips provides clear guidance and support for the clamping member, ensuring it remains in the correct position when pressing against the upper positioning plate 4. This design not only enhances the functionality of the fixture but also extends its service life to a certain extent, enabling it to maintain efficient and stable performance in various working environments. The reinforcing strip 41 of the upper positioning plate 4 enhances the stability and durability of the fixture through its structural design and also optimizes the battery's fixation effect.

[0031] It should be noted that during the clamping operation, the ingenious design of the clamping member 10 is that it can be tightly combined with the reinforcing strip 41 on the upper positioning plate 4. This design allows the clamping member 10 to be embedded in the frame formed by the reinforcing strip 41, thereby significantly improving the structural strength of the entire battery clamp. During the battery welding process, even when faced with the challenges of high temperature and high pressure, this structure can ensure that the battery is safely and firmly fixed in place. The frame formed by the reinforcing strip 41 provides evenly distributed pressure points, avoiding battery displacement or damage due to excessive local pressure, and reducing short circuits or other safety risks that may occur during the welding process.

[0032] It should also be noted that the design of the lower positioning plate 9 also reflects the importance attached to structural strength and stability. The multiple reinforcing grooves 91 distributed on the plate not only increase the strength of the lower positioning plate 9, but also help maintain the stability of its position during the welding process. The design of these grooves takes into account the heat and vibration that may be generated during welding, ensuring that the lower positioning plate 9 will not be displaced due to these factors, thereby ensuring the continuity and quality of the welding process. The positioning holes 92 on the lower positioning plate 9 are another important feature of the fixture design. These positioning holes match the size of the battery, allowing the fixture to adapt to batteries of different sizes. In actual operation, the positioning holes 92 in the upper positioning plate 4 and the lower positioning plate 9 can be adjusted according to the specific size of the battery. This flexibility ensures that the battery can be accurately positioned and firmly fixed in place. Regardless of how the size of the battery changes, the design of the upper positioning plate 4 and the lower positioning plate 9 also takes into account the ease of operation. The adjustment of the positioning holes 92 and the installation design of the clamping member 10 are simple.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
