[0045] The battery compartment skin is a protective structure covering the outside of the frame of the battery compartment. The battery compartment skin is used to block dust, moisture and the like from entering the inside of the battery compartment, and to protect the power battery and related electronic elements from pollution and corrosion. In addition, the battery compartment skin can also provide certain buffering and protection for the battery compartment, reduce the damage of external impact to the power battery, and prolong the service life of the power battery.

[0046] At present, the battery compartment skin is mainly made of steel plate, so it has very high structural strength. However, the density of the steel plate is large, which leads to the weight of the battery compartment skin being heavy, which is not conducive to the lightweight of the vehicle.

[0047] In order to solve the above technical problems, the present application provides a battery compartment skin assembly, a battery compartment and a vehicle. The battery compartment skin assembly, the battery compartment and the vehicle provided by the embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0048] Referring to Figure 1 , the present application provides a vehicle comprising a battery compartment 1. The vehicle of the present application includes but is not limited to a pure electric vehicle, a plug-in hybrid electric vehicle, an electric motorcycle, an electric bicycle and the like. The battery compartment 1 is a special component for storing power batteries. Referring to Figure 1The battery compartment 1 comprises a frame (not shown in the figure) and a battery compartment skin assembly 10, which is wrapped outside the frame. The battery compartment 1 can fix the power battery at a specific position of the vehicle, prevent the power battery from displacement due to bumping, sudden braking and the like during the driving of the vehicle, and avoid damage caused by the collision between the battery and other parts of the vehicle.

[0049] Referring to Figure 1 and Figure 2 The battery compartment skin assembly 10 comprises a skin body 100 and a fixing frame 200. The skin body 100 is a light plate. The fixing frame 200 is located at one side of the skin body 100 and is arranged at the edge of the skin body 100.

[0050] In use, the battery compartment skin assembly 10 can firmly fix the skin body 100 on the frame of the battery compartment 1 through the fixing frame 200. The fixing frame 200 can be made of a steel plate or a light plate. It can be understood that, since the main part of the skin body 100 is a light plate, the weight of the battery compartment skin assembly 10 can be effectively reduced even if a small part of the fixing frame 200 is still made of a steel plate. When the fixing frame 200 is also made of a light plate, the weight of the battery compartment skin assembly 10 can be further reduced.

[0051] In the scheme provided in the embodiments of the present application, the battery compartment skin assembly 10 with the light plate skin body 100 can be firmly fixed on the outside of the frame of the battery compartment 1 through the fixing frame 200. Since the overall weight of the skin body 100 and the fixing frame 200 is significantly reduced compared with the weight of the skin made of a steel plate in the prior art, the problem that the weight of the battery compartment skin is heavy and is not conducive to the lightweight of the vehicle can be solved by the present application.

[0052] Referring to Figure 1 and Figure 2 In some embodiments, the skin body 100 can be a polygon. The fixing frame 200 comprises a plurality of edge frames connected end to end, and the plurality of edge frames correspond one by one to a plurality of edges of the skin body 100.

[0053] As shown in Figure 2 , the skin body 100 can be a quadrilateral, and in addition, can be a triangle, a pentagon, a hexagon and the like. The outer contour shape of the fixing frame 200 is adapted to the shape of the skin body 100. For example, when the skin body 100 is a quadrilateral, the fixing frame 200 can comprise four edge frames connected end to end, and the edge frames are arranged at the edges of the quadrilateral.

[0054] In addition to the function of fixing the skin body 100 on the frame of the battery compartment 1, the fixing frame 200 can also have the function of pressing the skin body 100 to avoid deformation and wrinkles of the skin after being fixed.

[0055] It should be noted that the skin body 100 provided in this application can be a single-layer plate or a composite plate. The following is in conjunction with... Figures 2 to 4 The specific structure of the skin body 100 will be described in detail.

[0056] like Figure 2 and Figure 3 As shown, when the skin body 100 is a single-layer plate, the skin body 100 can be made of plastic plate, aluminum plate, etc.

[0057] Compared to ordinary carbon structural steel plates (such as Q235, Q345, etc.), it has a weight of approximately 7.85 g / cm³. 3 The density of plastic sheets is relatively low, typically ranging from 0.9 to 2.2 g / cm³. 3 For example, the density of polyethylene plastic sheets is only about 0.95 g / cm³. 3 Therefore, the weight of the plastic sheet skin body 100 can be significantly reduced. Furthermore, the plastic sheet has excellent chemical stability, resisting corrosion from various chemicals. Even in humid environments, the plastic sheet skin body 100 is not prone to rust. In humid environments, compared to steel sheet skin, the plastic sheet skin body 100 has a longer service life.

[0058] Aluminum sheets are typically made of aluminum alloys. There are many types of aluminum alloys, and the density of aluminum sheets varies slightly depending on the alloy. However, compared to steel sheets, aluminum alloys have a lower density, generally ranging from 2.58 to 2.9 g / cm³. 3 The thickness of aluminum plates is generally above 2mm, with common thicknesses including 3mm, 5mm, and 10mm. Designers can choose the appropriate thickness based on factors such as cost and strength. Aluminum plates possess high mechanical strength, good corrosion resistance, and excellent electrical and thermal conductivity. Therefore, the skin body 100 made of aluminum plates has sufficient strength and stability to resist erosion from natural factors such as wind and rain, exhibiting high durability. Furthermore, aluminum plates have excellent thermal conductivity, enabling rapid heat dissipation from the battery compartment 1. In addition, aluminum plates have high hardness, allowing the skin body 100 made of aluminum plates to better resist damage from external forces during use. Even under slight impacts or friction, the skin body 100 made of aluminum plates is not prone to significant damage, maintaining its appearance integrity. Aluminum plates are generally superior to plastic plates in terms of mechanical strength and durability, but their density and cost are higher than those of plastic plates. Designers can choose between aluminum plates or plastic plates for the skin body 100 based on actual needs.

[0059] See Figure 4When the skin body 100 adopts a composite plate, the skin body 100 can include a metal layer 110, a first plastic layer 120 and a second plastic layer 130, and the first plastic layer 120 and the second plastic layer 130 are fixedly arranged on both sides of the metal layer 110. That is, the metal layer 110 is sandwiched between the first plastic layer 120 and the second plastic layer 130.

[0060] The metal layer 110 as a base layer can provide stable support for the first plastic layer 120 and the second plastic layer 130, and ensure the structural stability of the skin body 100. The first plastic layer 120 and the second plastic layer 130 can be arranged on both sides of the metal layer 110 by means of compounding, adhesive bonding and the like.

[0061] The skin body 100 composed of the metal layer 110, the first plastic layer 120 and the second plastic layer 130 adopted by the embodiment has greater overall strength and rigidity than the skin body 100 composed of a single plastic plate, and can withstand greater pressure and impact, thus having a longer service life.

[0062] In some embodiments, the metal layer 110 can be a steel wire mesh or an aluminum sheet. The steel wire mesh is woven from high-strength steel wire and has high strength and durability, thus effectively improving the structural strength of the skin body 100. The thickness of the aluminum sheet is about 0.2-2 mm, which can effectively prevent dust and water vapor from entering the battery compartment 1.

[0063] Considering that plastic is easily corroded in harsh environments and is easily damaged under external forces such as impact and extrusion, in some embodiments, the surfaces of the first plastic layer 120 and the second plastic layer 130 are sequentially provided with a conductive layer and a color layer from inside to outside.

[0064] The conductive layer can be formed on the surface of the first plastic layer 120 by coating, chemical deposition and the like, and then a color layer can be electroplated on the surface of the conductive layer.

[0065] Since plastic itself is not conductive, it cannot be directly electroplated on the surface of the plastic, therefore, the present application first sets a conductive layer on the surface of the first plastic layer 120 and the second plastic layer 130, and the conductive layer can make the current pass through, thereby completing the electroplating process.

[0066] The color layer is a metal film with a specific color formed on the surface of the plastic through an electroplating process. The color of the metal film varies with the addition of pigments or metal ions in the electroplating solution, and the color of the metal film can be black, silver, gold, or colored with various color effects. The color layer not only effectively prevents the first plastic layer 120 and the second plastic layer 130 from being corroded, protects the metal layer 110 inside, enables the skin body 100 to be used stably in a humid, acidic, or alkaline environment for a long time, but also to some extent, can block the influence of sunlight and temperature changes on the first plastic layer 120 and the second plastic layer 130, improve the weather resistance, and maintain the appearance and performance of the skin body 100.

[0067] It should be noted that during the production process of the plastic, pinholes, bubble holes, and other holes will appear on the surface. The conductive layer can be firmly attached to the surface of the first plastic layer 120 and the second plastic layer 130 through the holes, and the conductive layer can increase the adhesion of the color layer, thereby effectively improving the durability of the skin body 100.

[0068] The embodiments of the present application can effectively improve the strength and durability of the skin body 100 by setting the conductive layer and the color layer, and further improve the service life of the battery compartment skin assembly 10.

[0069] Referring to Figure 3 In some embodiments, the battery compartment skin assembly 10 can further include an adhesive 300 arranged on the other side of the skin body 100 corresponding to the fixed frame 200.

[0070] The adhesive 300 can be a glue layer coated on the other side edge of the skin body 100, or a double-sided adhesive tape pasted on the other side edge of the skin body 100. The shape of the adhesive 300 can be flexibly set according to the shape of the skin body 100. For example, when the skin body 100 is a quadrilateral, the adhesive 300 can be arranged around the four edges of the skin body 100.

[0071] The embodiments of the present application set the adhesive 300 on one side of the skin body 100, which can make the edge of the other side of the skin body 100 tightly fit the frame of the battery compartment 1, further enhancing the sealing performance of the battery compartment skin assembly 10.

[0072] Referring to Figure 1 , Figure 2 and Figure 3 In some embodiments, the edge of the battery compartment skin assembly 10 is provided with a mounting hole 11 penetrating the skin body 100 and the fixed frame 200; the battery compartment 1 can further include a fastener 20, the fastener 20 is arranged in the mounting hole 11 to fix the battery compartment skin assembly 10 to the frame. The fastener 20 can be a screw, a bolt, a rivet, or the like.

[0073] It can be understood that when one side of the skin body 100 is provided with the adhesive member 300 using double-sided tape, the mounting hole 11 also penetrates the adhesive member 300. In this case, when the battery compartment skin assembly 10 is installed, the skin body 100 can be first adhered to the frame of the battery compartment 1 through the adhesive member 300, and then the battery compartment skin assembly 10 is firmly fixed to the frame of the battery compartment 1 through the fastener 20 penetrating the mounting hole 11.

[0074] The scheme provided by the embodiments of the present application can firmly fix the battery compartment skin assembly 10 to the frame of the battery compartment 1 through the fastener 20 penetrating the mounting hole 11.

[0075] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the description of the present application.
