Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery fixing device technology, and in particular to a battery fixing reinforcement structure based on adhesive. Background Technology
[0002] In battery module assembly technology, especially for cylindrical batteries, how to securely and stably fix a large number of individual batteries in designated positions is the foundation for ensuring the mechanical strength, electrical safety and service life of the module. Traditional fixing methods often use plastic brackets to rigidly limit the position through slots, or use adhesives to directly fill the gap between the battery and the battery compartment.
[0003] However, these traditional methods have obvious limitations. Rigid slots may damage the battery casing due to stress concentration when subjected to severe vibration or impact, or even cause internal short circuits. Ordinary potting or filling adhesives, although they have a decent fixing effect, tightly wrap the battery, which seriously hinders the heat dissipation during operation, causing the module temperature to rise and affecting battery performance and safety, thus creating a contradiction between "fixing" and "heat dissipation". In addition, the coordination between the assembly process and electrical connections is often overlooked, resulting in a cumbersome assembly process and low efficiency.
[0004] Therefore, a battery fixing and reinforcement structure based on adhesive is proposed to address the above problems. Utility Model Content
[0005] This invention provides a battery fixing and reinforcement structure based on adhesive, which not only provides a strong bond far exceeding that of traditional slots through large-area flexible contact, but also effectively absorbs vibration and impact; at the same time, it successfully solves the contradiction between fixing and heat dissipation, achieving efficient thermal management while ensuring the strongest fixing force; the entire structure highly integrates mechanical fixing, electrical connection and heat dissipation, which can simultaneously trigger the push rod to complete the airbag expansion and fixing and connect the two electrical circuits of the battery, greatly simplifying the assembly process and significantly improving production efficiency and module integration.
[0006] This utility model provides a battery fixing and reinforcing structure based on adhesive, including: a mounting frame and fixing components, wherein a top frame is movably connected to the top of the mounting frame; the fixing components are disposed inside the mounting frame, and the number of fixing components is set to multiple, wherein the fixing components include fixing cylinders, the fixing cylinders are installed at the bottom of the mounting frame, and the fixing cylinders contain batteries.
[0007] In the adhesive-based battery fixing and reinforcing structure of this utility model, the bottom end of the top frame is fixedly connected to a plurality of uniformly distributed limiting rings that match the fixing cylinder, and the bottom end of the limiting rings is fixedly connected to a plurality of uniformly distributed top rods.
[0008] In the adhesive-based battery fixing and reinforcing structure of this utility model, the fixing cylinder is provided with a plurality of evenly distributed sealing grooves, the sealing grooves and the top rod are arranged on the same straight line, and the sealing grooves and the top rod are slidably connected.
[0009] In the adhesive-based battery fixing and reinforcing structure of this utility model, a sealing block is slidably connected to the inner wall of the sealing groove, and an extrusion strip is fixedly connected to the inner wall of the sealing groove, with one end of the extrusion strip fixedly connected to the sealing block.
[0010] In the adhesive-based battery fixing and reinforcing structure of this utility model, the fixing cylinder has a plurality of evenly distributed flow holes that communicate with the sealing groove, and a wave-shaped heat-conducting airbag is installed inside the fixing cylinder.
[0011] In the adhesive-based battery fixing and reinforcing structure of one embodiment of this utility model, the inner end of the annular heat-conducting airbag is provided with a plurality of uniformly distributed adhesive strips, and the adhesive strips are connected to the inner wall of the fixing cylinder.
[0012] In an embodiment of the present invention, the adhesive-based battery fixing reinforcement structure has a flow hole located between a pair of adhesive strips.
[0013] The technical solution provided in this application embodiment can include the following beneficial effects: Utilizing air pressure to drive the flexible expansion of the ring-shaped heat-conducting airbag and working synergistically with the pre-coated adhesive, the battery achieves excellent fixation and buffering with a combination of rigidity and flexibility. Its wave-like shape not only provides a strong bond far exceeding that of traditional slots through large-area flexible contact, but also effectively absorbs vibration and impact. At the same time, the longitudinal heat dissipation channels naturally formed between the contact areas by this wave structure successfully solve the contradiction between fixation and heat dissipation, achieving efficient thermal management while ensuring the strongest fixation force. In addition, the entire structure highly integrates mechanical fixation, electrical connection, and heat dissipation. With only a single action of pressing down the top frame, the top rod can be triggered simultaneously to complete the airbag expansion and fixation and connect the electrical circuits of the two battery poles, greatly simplifying the assembly process and significantly improving production efficiency and module integration.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0020] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0021] like Figures 1 to 5As shown, this application provides a battery fixing reinforcement structure based on adhesive, including: a mounting frame 1 and a fixing component 2. The top of the mounting frame 1 is movably connected to a top frame 11. The fixing component 2 is disposed inside the mounting frame 1, and the number of fixing components 2 is set to multiple. The fixing component 2 includes a fixing cylinder 21, which is installed at the bottom of the mounting frame 1, and a battery 12 is disposed inside the fixing cylinder 21.
[0022] The lower end of the battery 12, that is, the end that is inserted into the bottom of the fixing cylinder 21, is provided with positive and negative electrode terminals. Correspondingly, a system connection contact point is installed at the bottom of the mounting frame 1, that is, at the bottom of each fixing cylinder 21. When the battery 12 is placed into the fixing cylinder 21, its lower electrode terminals will reliably contact the system connection contact point at the bottom of the mounting frame 1, thereby completing the electrical connection between the battery and the entire power system and establishing the main power transmission path.
[0023] To ensure stability at the top and provide possible auxiliary connections, the top frame 11 also participates in the electrical connection. Auxiliary elastic contacts can be provided inside the limiting ring 22 or at a corresponding position on the bottom of the top frame 11. When the top frame 11 is closed onto the mounting frame 1, these auxiliary elastic contacts gently and stably press against the corresponding electrode on the top of the battery 12, typically the other polarity or a measurement terminal. This design not only assists in fixation and current conduction but also allows for more precise monitoring of the voltage or temperature at the top of each battery 12.
[0024] The two sets of connections, "bottom system contact point of mounting frame 1 - lower electrode of battery 12" and "auxiliary elastic contact point of top frame 11 - upper electrode of battery 12," together form a complete, stable, and reliable electrical circuit. This design ensures that current can flow smoothly into and out of the battery, while mechanical fixing and electrical connection are completed simultaneously in a simple closing action, greatly improving the module's integration and assembly efficiency.
[0025] In an optional embodiment, the bottom end of the top frame 11 is fixedly connected to a plurality of evenly distributed limiting rings 22 that match the fixed cylinder 21. The bottom end of the limiting rings 22 is fixedly connected to a plurality of evenly distributed top rods 23. The fixed cylinder 21 is provided with a plurality of evenly distributed sealing grooves 24. The sealing grooves 24 and the top rods 23 are arranged on the same straight line and are slidably connected to the top rods 23. A sealing block is slidably connected to the inner wall of the sealing groove 24, and an extrusion strip is fixedly connected to the inner wall of the sealing groove 24. One end of the extrusion strip is fixedly connected to the sealing block.
[0026] The fixed cylinder 21 has multiple evenly distributed flow holes that communicate with the sealing groove 24, and a wave-shaped heat-conducting air bag 25 is installed inside the fixed cylinder 21. Multiple evenly distributed adhesive strips are provided at the inner end of the wave-shaped heat-conducting air bag 25. The adhesive strips are connected to the inner wall of the fixed cylinder 21, and the flow holes are located between a pair of adhesive strips.
[0027] For example, the adhesive-based battery fixing and reinforcement structure mainly consists of a mounting frame 1, a top frame 11, and multiple fixing components 2. The fixing components 2 are key to the function, and their core component is a fixing cylinder 21 installed at the bottom of the mounting frame 1, in which the battery 12 is placed.
[0028] Before installation, adhesive must be applied to the surface of the annular heat-conducting airbag 25 inside the fixing cylinder 21. When the top frame 11 is closed onto the mounting frame 1, the limiting ring 22 at the bottom of the top frame 11 will fit over the top of the battery 12. At the same time, multiple push rods 23 at the bottom of the limiting ring 22 will be precisely inserted into the corresponding sealing grooves 24 on the fixing cylinder 21. The downward movement of the push rods 23 will compress the sealing block in the sealing groove 24. Since the sealing groove is a closed space, the air inside is compressed, and the air pressure increases accordingly. This high-pressure airflow is then introduced into the annular heat-conducting airbag 25 through the flow holes opened on the wall of the fixing cylinder 21.
[0029] The influx of high-pressure gas causes the soft, wave-shaped heat-conducting airbag 25 to expand in a controlled, localized manner. The airbag bulges outward in its pre-designed wave shape, tightly abutting against the outer wall of the battery 12. Because the surface of the airbag is pre-coated with adhesive, a strong chemical bond is formed between the battery 12 and the airbag.
[0030] The flexible contact of the wave-shaped thermally conductive airbag 25 provides excellent cushioning and shock absorption for the battery, avoiding damage that may be caused by rigid fixation.
[0031] Secondly, the wavy contact surface forms a huge effective contact area after bonding, making the fixation extremely firm and reliable. Finally, the airbag and the battery surface are not completely attached. Its wavy structure makes the contact area and non-contact area the same. The areas not covered by the airbag naturally form longitudinal heat dissipation channels around the battery, where air can circulate freely, thereby efficiently removing the heat generated by the battery during operation, perfectly solving the contradiction that often exists between fixation and heat dissipation.
[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.
