Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and more specifically, to a fireproof and heat-insulating layer fixing structure for a new energy battery box that is easy to replace. Background Technology

[0002] In the field of new energy vehicles, the battery box is a key component of the battery system, and its fireproof and heat insulation performance is directly related to the safe operation of the battery and the reliability of the whole vehicle.

[0003] Based on the above, the inventors have discovered that traditional fireproof and heat-insulating layers for battery boxes are typically installed using adhesive or bolts. When these layers age or become damaged due to long-term use and require replacement, the disassembly process is cumbersome, consuming significant manpower and time, and potentially damaging the box or other components. Furthermore, adhesive bonding is prone to delamination at high temperatures, causing the fireproof and heat-insulating layer to loosen and affecting its insulation performance. Bolt fixing, on the other hand, requires specialized tools, making maintenance and replacement extremely inconvenient and reducing efficiency. Therefore, in view of this, the inventors have researched and improved upon existing structures to provide a more easily replaceable fireproof and heat-insulating layer fixing structure for new energy battery boxes, aiming to achieve greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a fireproof and heat-insulating layer fixing structure for new energy battery boxes that is easy to replace. Through innovative mechanical structure design, it can achieve rapid disassembly and assembly and stable fixing of the fireproof and heat-insulating layer, thereby improving the maintenance efficiency and safety performance of the battery box and effectively solving the problems of inconvenient replacement, time-consuming disassembly, easily damaged parts, and insufficient fixing reliability in the traditional fireproof and heat-insulating layer installation method for new energy battery boxes.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0006] A fireproof and heat-insulating layer fixing structure for a new energy battery box that is easy to replace includes a box body. U-shaped positioning plates are fixedly connected to the inner walls of both sides of the box body. Multiple locking teeth are fixedly connected to the inner walls of both sides of the U-shaped positioning plates. Two fireproof and heat-insulating plates are provided inside the box body. Mounting seats are fixedly connected to both sides of the fireproof and heat-insulating plates. Two spring-loaded latches are installed on the top of the mounting seats. The spring-loaded latches are engaged with the inner side walls of the U-shaped positioning plates. The spring-loaded latch includes two bearing seats fixed to the top of the mounting base, a rotating shaft rotatably connected between the two bearing seats, a buckle plate fixedly connected to the outer periphery of the rotating shaft, and a torque spring sleeved on the outer periphery of the rotating shaft. The two ends of the torque spring are fixedly connected to the bearing seats and the buckle plate, respectively.

[0007] Furthermore, each of the two buckle plates has a protrusion fixedly connected to the side that is far apart from each other, and the protrusion is engaged between two adjacent locking teeth.

[0008] Furthermore, two limiting plates are fixedly connected to the inner walls of both ends of the box body, and limiting blocks are fixedly connected to both ends of the fireproof and heat-insulating plate, with the limiting blocks slidably connected to the corresponding limiting plates.

[0009] Furthermore, a lid is fixedly connected to the top of the box.

[0010] Furthermore, multiple positioning posts are fixedly connected to the two fireproof and heat-insulating panels on the sides that are far apart from each other, and the multiple positioning posts are distributed at the four corners of the fireproof and heat-insulating panels.

[0011] Furthermore, the bottom end of the positioning post on the lower fireproof and heat-insulating plate abuts against the inner wall of the box, and the top end of the positioning post on the upper fireproof and heat-insulating plate abuts against the bottom of the box cover.

[0012] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: This solution, through the combined design of a U-shaped positioning plate and a spring-loaded locking buckle, achieves quick and easy fastening between the fireproof insulation board and the enclosure. During installation, simply align the mounting seats on both sides of the fireproof insulation board with the U-shaped positioning plate, and the torque spring will drive the buckle plate to automatically engage with the locking teeth, eliminating the need for additional tools and greatly simplifying the installation process. During disassembly, pressing the buckle plate compresses the torque spring, causing the protrusion to disengage from the locking teeth, allowing the fireproof insulation board to be pulled out directly for replacement. The entire process is convenient and effectively reduces the working time of maintenance personnel, significantly improving the replacement efficiency of the fireproof insulation layer.

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please see Figures 1-4 A fireproof and heat-insulating layer fixing structure for a new energy battery box that is easy to replace includes a box body 1. U-shaped positioning plates 2 are fixedly connected to the inner walls on both sides of the box body 1. Multiple locking teeth 3 are fixedly connected to the inner walls on both sides of the U-shaped positioning plates 2. Two fireproof and heat-insulating plates 4 are provided inside the box body 1. Mounting seats 5 are fixedly connected to both sides of the fireproof and heat-insulating plates 4. Two spring-loaded latches 6 are installed on the top of the mounting seats 5. The spring-loaded latches 6 are engaged with the inner side wall of the U-shaped positioning plates 2. The spring-loaded latch 6 includes two bearing seats 601 fixed to the top of the mounting base 5. A rotating shaft 602 is rotatably connected between the two bearing seats 601. A buckle plate 603 is fixedly connected to the outer periphery of the rotating shaft 602. A torque spring 604 is sleeved on the outer periphery of the rotating shaft 602. The two ends of the torque spring 604 are fixedly connected to the bearing seat 601 and the buckle plate 603 respectively.

[0017] See Figure 4 Both buckle plates 603 have protrusions fixedly connected to the sides of the two buckle plates that are far apart from each other, and the protrusions are engaged between two adjacent locking teeth 3. In use, the multiple distribution design of locking teeth 3 and spring-loaded buckles 6 ensures the stability of the fireproof and heat-insulating board 4 in the box 1, avoiding the problem of traditional glue sticking easily falling off and loosening in high temperature environment.

[0018] See Figure 1Two limiting plates 7 are fixedly connected to the inner walls of both ends of the housing 1, and two limiting blocks 8 are fixedly connected to both ends of the fireproof and heat-insulating plate 4. The limiting blocks 8 are slidably connected to the corresponding limiting plates 7. During use, the sliding cooperation between the limiting plates 7 and the limiting blocks 8 further guides and limits the installation position of the fireproof and heat-insulating plate 4, preventing it from shifting in a vibration environment such as vehicle driving, and ensuring the stability of the fireproof and heat-insulating effect.

[0019] See Figure 1 The top of the box 1 is fixedly connected to the box cover 9.

[0020] See Figure 1 Each of the two fireproof and heat-insulating boards 4 has multiple positioning posts 10 fixedly connected to the side of each other that is far apart, and the multiple positioning posts 10 are distributed at the four corners of the fireproof and heat-insulating board 4.

[0021] See Figure 3 The bottom end of the positioning post 10 on the lower fireproof and heat-insulating plate 4 abuts against the inner wall of the bottom of the box 1, and the top end of the positioning post 10 on the upper fireproof and heat-insulating plate 4 abuts against the bottom of the box cover 9. In use, the positioning post 10 can effectively fix the fireproof and heat-insulating plate 4 in the longitudinal position inside the box 1, so that the lower fireproof and heat-insulating plate 4 abuts against the inner wall of the bottom of the box 1 through the positioning post 10, and the upper fireproof and heat-insulating plate 4 abuts against the bottom of the box cover 9 through the positioning post 10, forming a rigid support in the vertical direction. This prevents the fireproof and heat-insulating plate 4 from deforming due to compression or vibration during use, thereby extending the service life of the fireproof and heat-insulating layer and improving the overall safety protection performance of the battery box 1.

[0022] When in use: First, remove the cover 9 from the top of the box body 1. Then, press the buckle plate 603 on the mounting base 5 on both sides of the fireproof and heat insulation board 4 to be replaced. After the buckle plate 603 is under force, it rotates around the rotating shaft 602 and compresses the torque spring 604, so that the protrusion on the outer side of the buckle plate 603 disengages from the locking teeth 3 on the inner side wall of the U-shaped positioning plate 2. At this time, the fireproof and heat insulation board 4 can be pulled out along the length direction of the limiting plate 7. When installing a new fireproof and heat-insulating board 4, first align the limiting blocks 8 at both ends with the corresponding limiting plates 7 and insert them. Push the fireproof and heat-insulating board 4 so that the mounting base 5 enters the U-shaped positioning plate 2. During the process, the inner wall of the U-shaped positioning plate 2 presses against the buckle plate 603, causing the rotating shaft 602 to rotate and the torque spring 604 to store energy. When the fireproof and heat-insulating board 4 moves to the preset position, the buckle plate 603 rebounds under the reset force of the torque spring 604, and the protrusion is engaged between two adjacent locking teeth 3 to complete the initial fixation. Finally, cover the box 9 so that the positioning post 10 of the upper fireproof and heat-insulating board 4 abuts against the bottom of the box 9, and the positioning post 10 of the lower fireproof and heat-insulating board 4 abuts against the bottom inner wall of the box 1, so as to achieve a stable installation of the fireproof and heat-insulating board 4 in all directions inside the box 1. The entire replacement process requires no special tools and can be completed by a single person in a short time, which greatly reduces maintenance costs. At the same time, the rigid connection of the mechanical structure ensures the reliability of the fireproof and heat insulation layer under various working conditions, effectively guaranteeing the fireproof and heat insulation effect of the battery box 1.
