Description

Technical Field

[0001] This utility model relates to the field of sodium-ion battery technology, and in particular to a small and lightweight sodium-ion battery start-up structure. Background Technology

[0002] With the continuous development of technology, sodium-ion batteries have gradually attracted attention in the fields of energy storage and power due to their advantages such as low cost and abundant resources. In the actual use of sodium-ion batteries, the performance of the starting structure is crucial to the overall performance of the battery.

[0003] However, traditional battery starting structures have some shortcomings. The positive and negative electrode connection methods are relatively complex, resulting in low energy transfer efficiency during the starting process. In addition, the connection structure is not stable enough. When subjected to vibration or external impact, the connection is prone to loosening, which affects the normal starting and safe use of the battery.

[0004] Therefore, we provide a small, lightweight sodium-ion battery startup structure. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a small, lightweight sodium-ion battery starting structure. The structure is relatively simple and can precisely move one end of the positive and negative terminals toward the center, making the connection between the integrated connector and the positive and negative terminals tighter, effectively reducing contact resistance and improving energy transfer efficiency.

[0006] In view of this, the present invention provides a small and lightweight sodium-ion battery starting structure, including a sodium-ion battery body, the sodium-ion battery body mainly including a battery shell, a sealing cover and a starting mechanism.

[0007] The starting mechanism includes an L-shaped plate mounted on a sealing cover, a control guide post on the L-shaped plate, the control guide post being connected to a transmission U-shaped frame below, and the lower end of the transmission U-shaped frame extending through the sealing cover into the inner cavity of the battery casing.

[0008] The starting mechanism also includes two sets of wedge guide blocks installed in the inner cavity. The two sets of wedge guide blocks are adapted to the transmission U-shaped frame and are provided with corresponding inclined grooves. The corresponding ends of the two sets of wedge guide blocks are respectively connected to the anode conductive column and the cathode conductive column. The wiring between the anode conductive column and the cathode conductive column is provided with an integrated main connecting piece. The integrated main connecting piece can be connected to external equipment.

[0009] Preferably, the inner cavity of the battery casing is provided with a transverse guide cavity, and the wedge guide blocks at the left and right ends are adapted to be installed in the transverse guide cavity and are connected through the guide post.

[0010] Preferably, the transverse guide cavity in the battery housing is further provided with a reset spring on both sides, one end of the reset spring being connected to the transverse guide cavity side wall and the other end being connected to the wedge guide block.

[0011] Preferably, the sidewalls of the anode conductive column and the cathode conductive column are also provided with welding connection plates.

[0012] Preferably, the anode conductive post and the cathode conductive post are provided with insertion posts at their insertion ports, and the two ends of the integrated main connecting piece are also adapted to be provided with insertion cavities.

[0013] Preferably, the sealing cover has positioning plates extending from both sides, and the sealing cover is detachably installed on the battery casing by the cooperation of the positioning plates at both ends.

[0014] Preferably, sealing rings are provided at the two through cavities above the sealing cover.

[0015] A spring-loaded spring is connected between the L-shaped plate and the transmission U-shaped frame. The upper end of the control guide post is rotatably provided with a cross-shaped pressure head. The cross-shaped pressure head drives the control guide post to move downward into the cross-shaped limiting groove of the L-shaped plate. The cross-shaped pressure head can be rotated 90° and locked in the cross-shaped limiting groove.

[0016] Compared with the prior art, this utility model provides a small and lightweight sodium-ion battery starting structure, which has the following beneficial effects:

[0017] 1. This utility model features a relatively simple starting mechanism design. By cooperating with the inclined groove of the wedge guide block and the transmission U-shaped frame, it can accurately push the anode conductive post and the cathode conductive post closer together, so that the integrated main connecting piece is tightly connected to the two poles, shortening the current transmission path, reducing resistance, greatly improving energy transmission efficiency, and providing a guarantee for efficient battery starting.

[0018] 2. This utility model allows the cross-shaped pressure head at the upper end of the guide post to rotate and press down, entering the cross-shaped limiting groove of the L-shaped plate and then rotating to lock. It is easy to operate and can firmly maintain the current position of the starting mechanism, avoiding accidental contact that could cause connection interruption.

[0019] 3. This utility model uses a pre-reserved welding point connection plate on the side wall of the anode conductive column and the cathode conductive column. When it is necessary to replace the electrode or make special circuit connections, it can be easily completed by welding point operation, which reduces the complexity of disassembling the overall structure.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1: A small, lightweight sodium-ion battery start-up structure, such as... Figures 1-4 As shown, it includes a sodium-ion battery body, which mainly includes a battery casing 1, a sealing cover 2, and a starting mechanism 3.

[0029] The starting mechanism 3 includes an L-shaped plate 31 installed on the sealing cover plate 2. The L-shaped plate 31 is provided with a control guide post 32. The control guide post 32 is connected to the transmission U-shaped frame 33 below. The lower end of the transmission U-shaped frame 33 extends through the sealing cover plate 2 to the inner cavity 11 of the battery casing 1.

[0030] The starting mechanism 3 also includes two sets of wedge guide blocks 34 installed in the inner cavity 11. The two sets of wedge guide blocks 34 are adapted to the transmission U-shaped frame 33 and are provided with corresponding inclined grooves. The corresponding ends of the two sets of wedge guide blocks 34 are respectively connected to the anode conductive post 37 and the cathode conductive post 371. The wiring between the anode conductive post 37 and the cathode conductive post 371 is provided with an integrated main connecting piece 38, which can be used to connect to external equipment.

[0031] In use, the cross-shaped pressure head 321 at the upper end of the control guide post 32 is pressed down. The cross-shaped pressure head 321 drives the control guide post 32 to move downward. The control guide post 32 pushes the transmission U-shaped frame 33 connected to it to move downward synchronously. The lower end of the transmission U-shaped frame 33 enters the inner cavity 11 of the battery casing 1 along the through channel of the sealing cover plate 2. Since the transmission U-shaped frame 33 and the inclined groove of the wedge guide block 34 are mutually adapted, the downward movement of the transmission U-shaped frame 33 causes the wedge guide block 34 to move towards the middle along the guide post 35 in the transverse guide cavity. The movement of the wedge guide block 34 drives the anode conductive post 37 and the cathode conductive post 371 connected to it to move closer to the middle. The insertion post 373 at the end of the anode conductive post 37 and the cathode conductive post 371 are respectively inserted into the insertion cavity at both ends of the integrated main connecting piece 38, completing the connection between the battery internal circuit and the integrated main connecting piece 38. At this time, the battery internal circuit is conductive and can supply power to external devices through the integrated main connecting piece 38 cable to realize battery startup.

[0032] like Figures 1-4 As shown, a transverse guide cavity is provided in the inner cavity 11 of the battery housing 1. The left and right wedge guide blocks 34 are adapted to be installed in the transverse guide cavity and are connected through the guide post 35. In use, the transverse guide cavity and the guide post 35 can provide a precise moving track for the wedge guide blocks 34, ensuring that they can only move along a specific transverse direction, avoiding deviation or shaking during transmission, and ensuring the accuracy of the movement of the anode conductive post 37 and the cathode conductive post 371.

[0033] like Figures 1-4 As shown, the transverse guide cavity in the battery housing 1 is also provided with a return spring 36 on both sides. One end of the return spring 36 is connected to the side wall of the transverse guide cavity, and the other end is connected to the wedge guide block 34. When the battery is started, the control guide post 32 drives the transmission U-shaped frame 33 to move down. The transmission U-shaped frame 33 pushes the wedge guide block 34 to move towards the middle in the transverse guide cavity through the inclined groove, thereby connecting the anode conductive post 37 and the cathode conductive post 371 with the integrated main connecting piece 38 to complete the circuit conduction. When it is necessary to stop the battery power supply, the downward locking of the control guide post 32 is released, and the elastic potential energy stored in the return spring 36 due to the previous compression will be released, pushing the wedge guide block 34 to move to both sides and return to the initial position.

[0034] like Figures 1-4As shown, the sidewalls of the anode conductive post 37 and the cathode conductive post 371 are also provided with solder joint connection plates 372. The reserved solder joint connection plates 372 provide additional connection points for the anode conductive post 37 and the cathode conductive post 371. By welding, other components that require electrical connection can be reliably connected to the anode conductive post 37 and the cathode conductive post 371, increasing the flexibility and stability of the battery connection with the external circuit.

[0035] like Figures 1-4 As shown, the anode conductive post 37 and the cathode conductive post 371 are provided with plug posts 373 at the plug-in port, and the two ends of the integrated total connecting piece 38 are also adapted to have plug-in cavities. The plug-in connection method can ensure the stability of the connection and effectively prevent the connection from becoming loose due to factors such as vibration and shaking during battery use, thereby ensuring the stability and reliability of battery performance.

[0036] like Figures 1-4 As shown, the sealing cover 2 has positioning plates 21 extending from both sides. The sealing cover 2 is detachably installed on the battery casing 1 through the cooperation of the positioning plates 21 at both ends. The two through cavities above the sealing cover 2 are provided with sealing rings 22, which can prevent external moisture, dust and other impurities from entering the battery through the through cavity openings, and avoid these impurities from causing corrosion, short circuits and other adverse effects on the electrodes, electrolyte and other components inside the battery.

[0037] Example 2: A small, lightweight sodium-ion battery start-up structure, such as Figures 1-4 As shown, a spring-loaded spring 322 is connected between the L-shaped plate 31 and the transmission U-shaped frame 33. The upper end of the control guide post 32 is rotatably provided with a cross-shaped pressure head 321. The cross-shaped pressure head 321 is covered with a rubber sleeve. The cross-shaped pressure head 321 drives the control guide post 32 to move downward into the cross-shaped limiting groove 311 of the L-shaped plate 31. The cross-shaped pressure head 321 can be rotated 90° and locked in the cross-shaped limiting groove 311.

[0038] When the battery needs to be started, the operator applies downward pressure to the cross-shaped indenter 321. Under this pressure, the cross-shaped indenter 321 moves the control guide post 32 downward until the anode conductive post 37 and the cathode conductive post 371 are inserted into the integrated main connecting piece 38. At this point, the cross-shaped indenter 321 reaches the position of the cross-shaped limiting groove 311 of the L-shaped plate 31 and enters it. Then, the operator rotates the cross-shaped indenter 321 90°. The shape of the cross-shaped indenter 321 is adapted to the cross-shaped limiting groove 311, and after rotation, it can be firmly locked in the cross-shaped limiting groove 311. Within 11, the control guide post 32 and the transmission U-shaped frame 33 connected to it are fixed in the current position, maintaining the connection between the anode conductive post 37, the cathode conductive post 371 and the integrated main connecting piece 38, ensuring that the battery continuously supplies power to external devices. At the same time, the battery may be subjected to vibration or shaking in the actual use environment. The rubber sleeve wrapped on the cross head 321 can buffer the impact of external vibration on the cross head 321, reduce the risk of accidental rotation or displacement of the cross head 321 due to vibration, and ensure the stable operation of the starting mechanism 3.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
