Description

Technical Field

[0001] This utility model relates to the field of battery tray assembly technology, and in particular to a multi-purpose storage box. Background Technology

[0002] With the rapid development of the automotive industry, energy issues are becoming increasingly urgent, and the environmental problems caused by automobiles are becoming increasingly serious. Developing the new energy vehicle industry is an effective way to alleviate the energy crisis, reduce greenhouse gas emissions, and reduce environmental pollution. At present, new energy vehicles have become an important direction for the transformation of the automotive industry. As the power source of new energy vehicles, the battery is the most important component of the whole vehicle and a landmark component that distinguishes it from other traditional fuel vehicles. Under the premise of ensuring the safety of battery function, the weight reduction of the main structural component tray, which accounts for 20-30% of the weight of the battery system, has become one of the main improvement goals. In the past, new energy vehicles mostly used steel materials to make power battery trays. Now, many companies mainly use aluminum alloy materials. Aluminum alloy has obvious advantages in compression and welding, and using it to produce battery trays can greatly improve the lightweight level of new energy vehicles.

[0003] However, under current technology, most battery pack frames lack cushioning capabilities. During the operation of new energy vehicles, they may encounter impacts and scratches, which can damage the battery pack itself, leading to battery pack failure and unnecessary economic losses. To address this issue, we propose a multi-purpose storage box. Utility Model Content

[0004] The purpose of this invention is to provide a multi-purpose safe deposit box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-purpose safe includes a box body. A set of symmetrical fixing plates is connected to both the left and right sides of the box body. Each set of fixing plates has a guide hole on its side closest to each other. A guide rod is slidably connected inside each set of guide holes. A connecting plate is connected to the upper and lower ends of each guide rod. A tension spring is connected to the side of each set of fixing plates away from each other. The ends of each tension spring away from each other are fixedly connected to the side of each connecting plate closest to each other. A rubber pad is connected to the inner wall of the box body, and the inner wall of the rubber pad has anti-slip grooves.

[0007] In a further embodiment, each of the connecting plates has two symmetrical threaded holes on its opposite side, and each threaded hole is threaded with a fastening bolt.

[0008] In a further embodiment, a sealing cover is connected to the upper surface of the housing by fasteners, and an insulating gasket is connected to the outer surface of the sealing cover.

[0009] In a further embodiment, multiple sets of equidistant ventilation openings are provided on both the front and back of the housing, and a dustproof net is connected to the inner wall of each ventilation opening.

[0010] In a further embodiment, the outer surface of the housing is connected with reinforcing ribs, which are made of plastic steel material.

[0011] In a further embodiment, the inner wall of the housing is connected to a cross-shaped mounting bracket, which is made of insulating material.

[0012] In a further embodiment, the left and right sides of the housing are connected to fixed brackets, and the two fixed brackets are connected to positioning plates on the side that is far apart from each other. The two positioning plates are provided with two symmetrical fixing holes on the side that is far apart from each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device, through the coordinated use of guide holes, guide rods, connecting plates, tension springs, rubber pads, and anti-slip grooves, solves the common problem of insufficient cushioning in battery pack frames. During the operation of new energy vehicles, when the battery pack is impacted, the pack will compress the rubber pads, which in turn compress the inner wall of the anti-slip grooves, increasing the friction between the rubber pads and the battery pack. Simultaneously, the pack will move the fixing plate, which in turn compresses the tension springs. The tension springs contract under pressure, and the contraction force pushes the fixing plate to move, causing the pack to return to its original position. Through the combined use of the rubber pads and tension springs, the pack is cushioned, preventing damage to the battery pack itself when impacted, thus avoiding damage to the battery pack and reducing unnecessary economic losses.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5In this utility model, a multi-purpose storage box includes a box body 1. A set of symmetrical fixing plates 2 are connected to both the left and right sides of the box body 1. Each set of fixing plates 2 has a guide hole 3 on its side closest to each other. A guide rod 4 is slidably connected inside each set of guide holes 3. A connecting plate 6 is connected to the upper and lower ends of each guide rod 4. A tension spring 5 is connected to the side of each set of fixing plates 2 away from each other. The ends of each set of tension springs 5 ​​away from each other are fixedly connected to the side of each set of connecting plates 6 close to each other. A rubber pad 16 is connected to the inner wall of the box body 1. The inner wall of the rubber pad 16 has anti-slip grooves 17. Through the above scheme, the rubber pad 16 and the tension spring 5 work together to cushion the box body 1, preventing damage to the battery pack when the box body 1 is impacted, thereby avoiding damage to the battery pack and reducing unnecessary economic losses.

[0025] Each connecting plate 6 has two symmetrical threaded holes 7 on its opposite side. Each threaded hole 7 is threaded with a fastening bolt 8, which can be used to install and fix the position of the buffer assembly, thereby ensuring the safety of the box 1 during vehicle operation and improving the practicality of the device. The upper surface of the box 1 is connected to a sealing cover plate 9 by fasteners. An insulating gasket is connected to the outer surface of the sealing cover plate 9. The insulating gasket improves the insulation performance of the upper surface of the box 1, avoids electrical contact between the battery pack inside the box 1 and the external environment, and further enhances the safety of the battery tray assembly. The sealing cover 9 is tightly connected to the housing 1 by fasteners, which effectively prevents dust, moisture and other impurities from entering the housing 1, protects the operating environment of the battery pack and extends the service life of the battery pack. Multiple sets of equidistant ventilation openings 10 are opened on the front and back of the housing 1. Each ventilation opening 10 is connected to a dustproof net on its inner wall. Through the multiple sets of equidistant ventilation openings 10, the heat inside the housing 1 can be effectively discharged to ensure the normal operation of the battery. The dustproof net can prevent dust and other debris from entering the housing 1 and damaging the battery.

[0026] The outer surface of the housing 1 is connected to reinforcing ribs 11, which are made of plastic steel. The use of plastic steel in the reinforcing ribs 11 not only improves the overall strength of the housing 1, but also reduces the weight of the battery tray assembly, making it easier to handle and install. The inner wall of the housing 1 is connected to a cross mounting bracket 12, which is made of insulating material. This effectively prevents the current generated by the battery during charging and discharging from damaging the housing 1, thus improving the safety of the battery tray assembly. The left and right sides of the housing 1 are connected to fixed brackets 13. The side of the two fixed brackets 13 that is far apart from each other is connected to a positioning plate 14. The side of the two positioning plates 14 that is far apart from each other has two symmetrical fixing holes 15. The fixed brackets 13 and the positioning plates 14 are designed to facilitate the fixing of the battery tray assembly to the body of the new energy vehicle. The fixing holes 15 can be used with bolts and other fasteners to achieve a stable installation of the battery tray assembly.

[0027] The working principle of this utility model is as follows:

[0028] When installing the battery, it is first placed on the rubber pad 16 inside the housing 1. The anti-slip groove 17 increases the friction between the battery and the rubber pad 16, preventing the battery from shaking or shifting during transportation. Then, the fastening bolt 8 is passed through the threaded hole 7 to further secure the housing 1, ensuring the stability and safety of the battery. During the operation of the new energy vehicle, when the housing 1 is impacted, the housing 1 will compress the rubber pad 16, and the rubber pad 16 will compress the inner wall of the anti-slip groove 17, increasing the friction between the rubber pad 16 and the battery pack. At the same time, the housing 1 will move the fixing plate 2, and the moving fixing plate 2 will compress the tension spring 5. The tension spring 5 will contract under force, and the contraction force of the tension spring 5 will push the fixing plate 2 to move. The fixing plate 2 will then move the housing 1 back to its original position. Through the combined use of the rubber pad 16 and the tension spring 5, the housing 1 is cushioned, preventing damage to the battery pack itself when the housing 1 is impacted, ensuring the normal operation of the battery pack inside the housing 1, and effectively improving the safety and reliability of the new energy vehicle.
