[0005] This application provides a bottom protection plate and an electrical device to solve the technical problem of friction between the composite layer of the bottom protection plate and the battery pack in related technologies.

[0006] In a first aspect, embodiments of this application provide a bottom protective plate, comprising:

[0007] A base plate, which is used to mount electrical equipment;

[0008] A structural reinforcement frame is disposed on the base plate;

[0009] An elastic filling mechanism is provided on the base plate and fixed to the structural reinforcement frame. The elastic filling mechanism is used to connect to the battery pack of the electrical equipment.

[0010] In some embodiments, the elastic filling mechanism is a foam component used to fill the base plate.

[0011] In some embodiments, the structural reinforcement frame is a metal component.

[0022] This application provides a bottom protection plate and an electrical device. The bottom protection plate provided by this application adopts an elastic filling mechanism. Because the elastic filling mechanism is elastic and is connected to the battery pack, when the bottom plate causes the elastic filling mechanism to bounce, the bottom plate can cause the elastic filling mechanism to elastically abut against the battery pack, thereby preventing the battery pack from being damaged due to continuous friction between the elastic filling mechanism and the battery pack, thus improving the protective effect of the bottom protection plate on the battery pack. Furthermore, by adopting the elastic filling mechanism, the elastic filling mechanism can fix the structural reinforcement frame and the bottom plate, thereby fixing the elastic filling mechanism, the structural reinforcement frame and the bottom plate simultaneously, thereby improving the strength of the bottom protection plate and further improving the protective effect of the bottom protection plate on the battery pack.

[0033] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] The bottom protection plate of the related technology includes a composite layer and a steel plate. The composite layer has two layers, and the steel plate is placed between the two composite layers. The composite layer is a glass fiber reinforced polypropylene composite material.

[0036] However, the composite layer made of glass fiber reinforced polypropylene has high stiffness and strength. When the vehicle is bumpy, the composite layer and the battery pack rub against each other, which can easily damage the battery pack.

[0037] To address the aforementioned technical problems, this application provides a bottom protection plate and an electrical device. By filling the bottom plate with foam, the foam can fix the structural reinforcement frame to the bottom plate, and the foam can be simultaneously fixed with the structural reinforcement frame and the bottom plate. This increases the strength of the metal parts, the bottom plate, and the foam, thereby improving their impact resistance. Because the foam has a certain degree of elasticity and is connected to the battery pack, when the bottom plate causes the elastic filling mechanism to vibrate, the bottom plate can cause the elastic filling mechanism to elastically abut against the battery pack, thus preventing damage to the battery pack due to continuous friction between the elastic filling mechanism and the battery pack. This improves the protective effect of the bottom protection plate on the battery pack. When water enters the bottom plate, a humidity sensor can alert the user when the humidity exceeds a preset humidity level, thus preventing water from entering the bottom plate from affecting the battery pack.

[0038] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0039] Combination Figures 1 to 3 This application provides a bottom protective plate, comprising:

[0040] Base plate 100, base plate 100 is used to install on electrical equipment;

[0041] Structural reinforcement frame 200 is installed on base plate 100;

[0042] The elastic filling mechanism 300 is used to be installed on the base plate 100 and fixed to the structural reinforcement frame 200. The elastic filling mechanism 300 is used to connect to the battery pack of the electrical equipment.

[0043] In this embodiment, the electrical equipment is a car; the thickness of the base plate 100 is 1mm; the base plate 100 is rectangular; in other embodiments, the shape of the base plate 100 can be adapted as needed, for example, the base plate 100 can be set to an ellipse.

[0044] By adopting the above technical solution and the setting of the elastic filling mechanism 300, because the elastic filling mechanism 300 is elastic and connected to the battery pack, when the base plate 100 causes the elastic filling mechanism 300 to bounce, the base plate 100 can cause the elastic filling mechanism 300 to elastically abut against the battery pack, thereby preventing the elastic filling mechanism 300 from continuously rubbing against the battery pack and causing damage to the battery pack, thus improving the protective effect of the bottom guard plate on the battery pack; and by adopting the setting of the elastic filling mechanism 300, the elastic filling mechanism 300 can fix the structural reinforcing frame 200 and the base plate 100, thereby fixing the elastic filling mechanism 300, the structural reinforcing frame 200 and the base plate 100 simultaneously, thereby improving the strength of the bottom guard plate and further improving the protective effect of the bottom guard plate on the battery pack; by adopting the setting of the structural reinforcing frame 200.

[0045] Combination Figures 1 to 3 The elastic filling mechanism 300 is a foam component, which is used to fill the base plate 100.

[0046] In this embodiment, the thickness of the foam is 0.8 mm; the foam is made of polyurethane, polyethylene and polypropylene or ethylene-vinyl acetate copolymer; by using polyurethane foam material, it has excellent elasticity and wear resistance; by using a mixed foam material of polyethylene and polypropylene, it has good cushioning and heat insulation properties, and has high elasticity, which can absorb impact and return to its original state; by using ethylene-vinyl acetate copolymer, it has a certain degree of elasticity.

[0047] In this application, when the foamed component is filled onto the base plate 100, the structural reinforcement frame 200 can be embedded within the foamed component, thereby indirectly improving the strength of the foamed component and the base plate 100, and further enhancing the protective effect of the bottom guard plate on the battery pack. By employing the foamed component, it possesses excellent impact absorption performance, capable of absorbing and dispersing impact forces when the vehicle encounters bumps or collisions, reducing direct impact on the battery pack. Foamed components are typically lighter than traditional rigid materials, which helps reduce the overall weight of the vehicle and improve energy efficiency, especially important for increasing driving range in electric vehicles. Foamed components have good thermal insulation properties, protecting the battery pack from external temperature changes, maintaining the battery's optimal operating temperature, and extending battery life. Foamed components can reduce noise transmission, lowering vehicle operating noise and improving ride comfort. Foamed components are generally resistant to various chemicals, protecting the battery pack from corrosive substances. Compared to traditional rigid protective materials, foamed components are generally less expensive, helping to reduce the overall vehicle production cost.

[0048] Combination Figures 1 to 3 The structural reinforcement frame 200 is made of metal.

[0049] In this embodiment, the thickness of the metal part is 1 mm; the metal part is a galvanized steel frame; in other embodiments, the metal part can also be made of stainless steel, etc.

[0050] In this application, the metal components significantly improve the overall rigidity and strength of the base plate 100, enabling it to withstand greater impact and pressure, thus protecting the battery pack from damage. The metal components disperse impact forces over a wider area, reducing localized stress concentration and thereby lowering the risk of damage to the battery pack. The addition of metal components can extend the service life of the base plate 100, as metal is generally more resistant to wear and corrosion than plastics or other materials. Metal components have good thermal conductivity, which helps dissipate heat from the battery pack, especially under high loads, helping to maintain the battery's optimal operating temperature. Metal components are generally resistant to a variety of chemicals, protecting the battery pack from corrosive substances.

[0051] Combination Figures 1 to 3 The structural reinforcement frame 200 includes a frame 210 and a reinforcement component 220. The frame 210 is mounted on the base plate 100, and the reinforcement component 220 is mounted inside the frame 210.

[0052] In this embodiment, the frame 210 is rectangular, and the area of ​​the rectangular frame 210 is smaller than the area of ​​the base plate 100. The position of the rectangular frame 210 on the base plate 100 can be adjusted as needed, for example, the frame 210 can be positioned opposite the frame of the battery pack. In other embodiments, the shape of the frame 210 can be adjusted as needed, for example, the frame 210 can be set as a triangle.

[0053] In this application, the rectangular frame 210 provides a robust foundation, enhancing the overall stability of the base plate 100 and effectively resisting torsion and bending. The reinforcing component 220, disposed within the frame 210, helps to distribute the impact force more evenly, reducing localized stress concentration and protecting the battery pack from damage. The combination of the frame 210 and the reinforcing component 220 further improves the strength of the base plate 100, thereby extending its service life.

[0054] Combination Figures 1 to 3 The reinforcing component 220 includes rods 221 and reinforcing members 223. Multiple rods 221 are provided, and the multiple rods 221 are arranged horizontally and vertically in the frame 210 to form multiple installation spaces 222 in the frame 210. The reinforcing members 223 are provided in the installation spaces 222.

[0055] In this embodiment, the rod 221 includes three first reinforcing rods and two second reinforcing rods; the three first reinforcing rods are evenly spaced along the length of the frame 210, the second reinforcing rods are perpendicular to the first reinforcing rods, and the two second reinforcing rods are evenly spaced along the width of the frame 210; the multiple rods 221 are arranged on the same plane, and the multiple rods 221 and the frame 210 are also arranged on the same plane; the rods 221 can be welded to the frame 210 or integrally formed with the frame 210; the three first reinforcing rods and the two second reinforcing rods together with the frame 210 form twelve installation spaces 222, and each installation space 222 is rectangular.

[0056] In this application, by employing multiple rods 221 and arranging them horizontally and vertically within the frame 210, the rods 221 can provide support around the frame 210, thereby further improving the strength of the frame 210 and indirectly improving the strength of the base plate 100, thus enhancing the impact resistance of the base plate 100. Furthermore, by employing reinforcing members 223, the reinforcing members 223 can support the multiple rods 221 within multiple installation spaces 222, further improving the strength of the frame 210 and indirectly enhancing the strength of the base plate 100, thus further enhancing the impact resistance of the base plate 100.

[0057] Combination Figures 1 to 3 The reinforcing member 223 includes at least two intersecting portions 2231.

[0058] In this embodiment, each installation space 222 is provided with two intersecting parts 2231. The two intersecting parts 2231 are respectively arranged along the diagonal of the rectangular installation space 222. The intersecting parts 2231 can be welded to the rod body 221 or integrally arranged with the rod body 221. The intersecting parts 2231 and the rod body 221 are arranged on the same plane.

[0059] In this application, by employing two intersecting cross portions 2231, the cross portions 2231 can support the rods 221 arranged in different directions, thereby further improving the strength of the entire structural reinforcement frame 200, thereby further improving the strength of the base plate 100, and thus improving the impact resistance of the base plate 100.

[0060] Combination Figures 1 to 3 The bottom guard plate also includes a positioning mechanism 400, which is set on the bottom plate 100 and is used to position the structural reinforcement frame 200 on the bottom plate 100.

[0061] In this application, by employing a positioning mechanism 400, the structural reinforcement frame 200 can be positioned on the base plate 100 before the foam is filled. This prevents the structural reinforcement frame 200 from shifting on the base plate 100 during foam filling, thus preventing the structural reinforcement frame 200 from being in an offset position and failing to support the base plate 100. This indirectly improves the strength of the base plate 100 and enhances its protection of the battery. Furthermore, by employing the positioning mechanism 400, installers can directly install the structural reinforcement frame 200 without having to measure its position again on the base plate 100, thereby improving the ease of installation.

[0062] Combination Figures 1 to 3 The positioning mechanism 400 includes at least one latch for engaging or disengaging with the structural reinforcement frame 200 to fix or detach the structural reinforcement frame 200 from the base plate 100.

[0063] In this embodiment, eight buckles are provided, with two buckles on each side of the rectangular frame 210; the buckles have snap-fit ​​grooves for snapping into or out of the frame 210, so that the structural reinforcement frame 200 is fixed or detached from the base plate 100.

[0064] In this application, by adopting a snap-on design, when the structural reinforcement frame 200 needs to be positioned, it can be simply engaged with the snap-on mechanism, making installation convenient and simple, and further improving the ease of installation of the structural reinforcement frame 200. When the structural reinforcement frame 200 needs to be removed, it can be easily disengaged from the snap-on mechanism by applying force, making disassembly convenient and simple, and further improving the ease of disassembly of the structural reinforcement frame 200.

[0065] Combination Figures 1 to 3 The bottom plate also includes a detection mechanism 500, which is installed on the bottom plate 100. The detection mechanism 500 is used to detect the humidity of the bottom plate 100 and to alert the user through electrical equipment when the humidity is greater than the preset humidity.

[0066] In this embodiment, the detection mechanism 500 can alert the user through the vehicle's interactive system, such as the vehicle's infotainment display or dashboard, when the humidity is greater than a preset humidity.

[0067] In this application, by employing a detection agency 500, humidity changes can be detected in a timely manner, and the user will be alerted when water enters the underbody 100 or the humidity is too high. This helps the user take timely measures to avoid potential damage. By monitoring humidity, corrosion and short-circuit risks caused by moisture to the battery pack can be prevented, extending battery life. Moisture may cause short circuits in the battery pack, increasing the risk of fire. Humidity monitoring helps improve vehicle safety. Users do not need to manually check the humidity status of the underbody; the system will automatically remind them, improving ease of use. Humidity monitoring is particularly important for vehicles used in humid environments or rainy areas, helping the vehicle adapt to different environmental conditions. By preventing various problems caused by excessive humidity, the overall lifespan of the vehicle can be extended. The system can remind users to perform regular maintenance based on humidity data, such as cleaning the underbody.

[0068] Combination Figures 1 to 3 The testing unit 500 includes at least one humidity sensor.

[0069] In this embodiment, four humidity sensors are provided. The four humidity sensors are set on the base plate 100 and distributed along the circumference of the structural reinforcement frame 200. The humidity sensors can be capacitive humidity sensors, resistive humidity sensors, or thermal humidity sensors, etc.

[0070] In this application, the humidity sensor can continuously monitor humidity changes in real time, providing instant data. Furthermore, the humidity sensor can automatically detect humidity without manual intervention, reducing labor costs. The humidity sensor provides high-precision measurement results, ensuring data accuracy. The humidity sensor has high reliability and can operate stably under various environmental conditions.

[0071] Combination Figures 1 to 3 A flange 110 is provided along the circumference of the base plate 100, and the structural reinforcement frame 200 and the elastic filling mechanism 300 are both located inside the flange 110.

[0072] In this embodiment, the flange 110 is provided along the axial edge of the rectangular base plate 100, the flange 110 is perpendicular to the base plate 100, and the flange 110 is provided with a plurality of bolt holes, so as to facilitate fixing the flange 110 to the car through the bolt holes.

[0073] In this application, by adopting the flange 110, the flange 110 can block external water ingress, preventing water from flowing onto the base plate 100 and affecting the battery pack when the vehicle is in motion, thereby further improving battery safety and extending battery life.

[0074] Combination Figures 1 to 3 The base plate is made of fiberglass.

[0075] In this embodiment, fiberglass, also known as glass fiber reinforced plastic, is a composite material mainly made of the following two materials:

[0076] Glass fiber: This is an inorganic non-metallic material made of glass, possessing properties such as high strength, high modulus, and corrosion resistance. Glass fiber can be made into different forms, such as continuous fibers, chopped fibers, and woven fabrics, to meet various application requirements.

[0077] Resin matrix: Commonly used resin matrices include unsaturated polyester resin (UPR), epoxy resin (EP), and phenolic resin (PF). The main function of the resin matrix is ​​to bond the glass fibers together to form a strong structure and provide protection.

[0078] In this application, fiberglass reinforced plastic (FRP) possesses good strength and rigidity, providing robust protection for the vehicle's battery pack or chassis. FRP exhibits excellent resistance to various chemicals, including acids, alkalis, and salts, making it suitable for use in diverse environmental conditions. Compared to metals, FRP has a lower density, contributing to vehicle weight reduction and improved performance. FRP has good wear resistance, making it suitable for withstanding impacts from stones and obstacles on the undercarriage. FRP is an excellent electrical insulator, helping to protect the battery pack from electrical interference. FRP can withstand certain temperature variations and is not easily deformed or damaged by temperature fluctuations. FRP is rust-resistant, reducing maintenance costs due to corrosion. FRP has good impact resistance, absorbing and dispersing impact forces upon impact, protecting the vehicle chassis. FRP can absorb some noise and vibration, improving ride comfort.

[0079] This application also provides an electrical device, characterized in that it includes a body and a bottom protective plate of any of the above embodiments disposed on the body.

[0080] The specific structure of the bottom protective plate has been described in detail in the above embodiments, and will not be repeated here.

[0081] In this embodiment, the electrical device is a car; in other embodiments, the electrical device can be other electrical devices that require battery protection.

[0082] The electrical equipment provided in this application embodiment, by setting a bottom protective plate, fills the bottom plate 100 with foam, so that the foam can fix the structural reinforcement frame 200 to the bottom plate 100, and the foam can be fixed simultaneously with the structural reinforcement frame 200 and the bottom plate 100. This improves the strength of the metal parts of the bottom plate 100 and the foam, thereby improving the impact resistance of the foam and the bottom plate 100. Because the foam has a certain elasticity and is connected to the battery pack, when the bottom plate 100 drives the elastic filling mechanism 300 to bounce, the bottom plate 100 can drive the elastic filling mechanism 300 to elastically abut against the battery pack, thereby preventing the elastic filling mechanism 300 from continuously rubbing against the battery pack and causing damage to the battery pack, thus improving the protective effect of the bottom protective plate on the battery pack. When water enters the bottom plate 100, the humidity sensor can alert the user when the humidity is higher than the preset humidity, thereby preventing water from entering the bottom plate 100 from affecting the battery pack.

[0083] It should be noted that other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. The present invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is limited only by the appended claims.
