Technical Field

[0001] This application relates to the field of battery protection technology, and in particular to a protective plate assembly, a protective device, and an electrical device. Background Technology

[0002] The power battery packs of new energy vehicles are generally located at the bottom of the vehicle. When the vehicle is driving on poor road conditions or when there are foreign objects on the road, the bottom of the battery pack is prone to scratches. At the same time, the bottom of the battery pack is exposed to the outside for a long time and is susceptible to damage from corrosive environments such as acids and alkalis. All of these factors may affect the protective performance of the bottom of the battery pack.

[0003] Existing designs typically involve installing an integrated underbody protection plate at the bottom of the vehicle to protect the battery pack. However, when the underbody protection plate is damaged, the entire integrated underbody protection plate needs to be disassembled and replaced, which is a rather cumbersome process.

[0034] The accompanying drawings have illustrated 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 specific embodiments. Detailed Implementation

[0035] 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.

[0036] The power battery packs of new energy vehicles are generally located at the bottom of the vehicle. When the vehicle is driving on poor road conditions or when there are foreign objects on the road, the bottom of the battery pack is prone to scratches. At the same time, the bottom of the battery pack is exposed to the outside for a long time and is susceptible to damage from corrosive environments such as acids and alkalis. All of these factors may affect the protective performance of the bottom of the battery pack.

[0037] Existing designs typically involve installing an integrated underbody protection plate at the bottom of the vehicle to protect the battery pack. However, when the underbody protection plate is damaged, the entire integrated underbody protection plate needs to be disassembled and replaced, which is a rather cumbersome process.

[0038] The protective panel assembly, protective device, and electrical equipment provided in this application only require targeted disassembly of the damaged and deformed panels and splicing parts to replace the damaged and deformed panels, thereby allowing the protective panel assembly to continue to be used without disassembling other undamaged and deformed panels, making it more convenient to use.

[0039] 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.

[0040] Firstly, such as Figures 1-5 As shown in the embodiment of this application, a protective plate assembly is provided, including multiple panels 100. The multiple panels 100 are arranged sequentially along their extension direction. The multiple panels 100 arranged sequentially can form a protective area. One side of the protective area is used to accommodate the object to be protected, so that the multiple panels 100 can jointly protect the object to be protected on one side. This ensures that the impact force from the outside towards the object to be protected can only act on the multiple panels 100 and will not be transmitted to the object to be protected itself, thereby effectively protecting the object to be protected.

[0041] Furthermore, the protective panel assembly in this embodiment also includes a splicing member 200. When the number of panels 100 is two, such as... Figure 1 As shown, the number of splicing components 200 is one. When the number of assembly panels 100 is greater than two, as shown... Figure 4 and Figure 5As shown, there are multiple splice pieces 200.

[0042] In this embodiment of the protective panel assembly, during assembly, a splicing member 200 is provided between two adjacent panel 100s, thereby enabling the two adjacent panel 100s to be spliced ​​and connected through the splicing member 200, and allowing multiple panel 100s to be sequentially spliced ​​to form a protective area. More specifically, a splicing groove 300 is provided on the splicing member 200. When the splicing member 200 is placed between two adjacent panel 100s, the sides of the two adjacent panel 100s near the splicing member 200 can be embedded in the splicing groove 300, thereby realizing the connection between the splicing member 200 and the two adjacent panel 100s. Since the sides of the panel 100 are embedded in the splicing groove 300, the connection between the panel 100 and the splicing member 200 is detachable, and the splicing connection between two adjacent panel 100s is also detachable.

[0043] It is worth mentioning that when an external impact force is directed towards the component to be protected, due to the design of the protective plate assembly in this embodiment, the impact force will only act on the protective plate assembly and not on the component to be protected. Therefore, it can better protect the component to be protected. Furthermore, when the external impact force acts on the protective plate assembly, it will specifically act on at least one panel 100. When the impact force is large enough, it will cause at least one panel 100 to deform. In this embodiment, the protective plate assembly only needs to be selectively disassembled from the corresponding damaged and deformed panel 100 and splice 200 to replace the damaged and deformed panel 100, so that the protective plate assembly can continue to be used without disassembling other undamaged and deformed panels 100, making it more convenient to use. For example, when there are three panels 100, the three panels 100 are arranged in sequence along their extension direction and are spliced ​​together by two splicing parts 200. When the panel 100 in the middle position is damaged or deformed, it is only necessary to disassemble and replace the panel 100 in the middle position, without having to disassemble and replace all three panels 100.

[0044] In some embodiments, the assembly panel 100 includes a first side, a second side, a third side, and a fourth side. The first side and the second side are positioned opposite each other along a first direction, and the third side and the fourth side are positioned opposite each other along a second direction. The first direction and the second direction are both parallel to the extension direction of the assembly panel 100, and the first direction and the second direction are kept intersecting each other.

[0045] Since the assembly plates 100 in this embodiment are all quadrilaterals, the two ends of the first side of the assembly plate 100 are connected to the third side and the fourth side respectively, and the two ends of the second side of the assembly plate 100 are connected to the third side and the fourth side respectively.

[0046] It should be noted that the first side and the second side are opposite each other in the first direction. That is, the first side and the second side can be parallel to each other or they can intersect each other. Similarly, the third side and the fourth side are opposite each other in the second direction. That is, the third side and the fourth side can be parallel to each other or they can intersect each other. No particular limitation is made in this regard.

[0047] In some embodiments, combined with Figure 1 As shown, the multiple panels 100 include a first panel 110 and a second panel 120, wherein the first panel 110 and the second panel 120 are adjacent to each other, and a splicing member 200 is provided between the first panel 110 and the second panel 120, so that the first panel 110 and the second panel 120 are spliced ​​and connected by the splicing member 200.

[0048] Furthermore, in this embodiment of the application, the first side 101a of the first group of plates 110 faces the second group of plates 120, while the second side 102b of the second group of plates 120 faces the first group of plates 110. Therefore, the splicing member 200 is located between the first side 101a of the first group of plates 110 and the second side 102b of the second group of plates 120.

[0049] It is understood that the first side 101a and the second side 102a of the first group of plates 110 are opposite to each other and along the first direction, while the first side 101b and the second side 102b of the second group of plates 120 are opposite to each other and along the first direction. The splicing component 200 has a first splicing groove 310 and a second splicing groove 320 formed on opposite sides along the first direction, wherein the first side 101a of the first group of plates 110 is embedded in the first splicing groove 310, and the second side 102b of the second group of plates 120 is embedded in the second splicing groove 320, thereby enabling the splicing connection of the splicing component 200 to the first group of plates 110 and the second group of plates 120 to be better realized.

[0050] When the first side 101a of the first panel 110 is removed from the first splicing groove 310, the first panel 110 can be disassembled from the splicing component 200, thereby disassembling the first panel 110 from the second panel 120. Similarly, when the second side 102b of the second panel 120 is removed from the second splicing groove 320, the second panel 120 can be disassembled from the splicing component 200, thereby disassembling the second panel 120 from the first panel 110. When the first panel 110 or the second panel 120 is damaged or deformed, only the corresponding first panel 110 or second panel 120 needs to be disassembled and replaced, without having to disassemble both the first panel 110 and the second panel 120 from the splicing component 200.

[0051] In some embodiments, combined with Figure 2 and Figure 3 As shown, the splicing component 200 includes a plate 210, which is specifically located at the splicing point of the first group of plates 110 and the second group of plates 120, and the plate 210 is located on the same side surface of the first group of plates 110 and the second group of plates 120; a protrusion 220 is also provided on one side of the plate 210, and the protrusion 220 is located between the first side edge 101a of the first group of plates 110 and the second side edge 102b of the second group of plates 120.

[0052] Furthermore, in the first direction, the protrusion 220 is located at the middle position of the plate 210, and the protrusion 220 near the side wall of the first group of plates 110 forms a first splicing groove 310 with the side wall of the plate 210, and the protrusion 220 near the side wall of the second group of plates 120 forms a second splicing groove 320 with the side wall of the plate 210. That is, the two sides of the protrusion 220 can respectively form the first splicing groove 310 and the second splicing groove 320 with the surface of the plate 210.

[0053] When splicing the first group of plates 110 and the second group of plates 120, the splicing component 200 is placed between the first group of plates 110 and the second group of plates 120, and the first side 101a of the first group of plates 110 is embedded in the first splicing groove 310, and the second side 102b of the second group of plates 120 is embedded in the second splicing groove 320, thereby better realizing the splicing connection between the first group of plates 110 and the second group of plates 120.

[0054] In some embodiments, when the first side 101a of the first panel 110 is embedded in the first splicing groove 310, a sealing element is provided between the first side 101a of the first panel 110 and the first splicing groove 310. The sealing element can specifically be a rubber element, so that the first side 101a of the first panel 110 and the first splicing groove 310 can form a sealing effect, thereby enabling the protective panel assembly in this embodiment to also have the effect of waterproofing and dustproofing. Similarly, when the second side 102b of the second panel 120 is embedded in the second splicing groove 320, a sealing element is also provided between the second side 102b of the second panel 120 and the second splicing groove 320. The sealing element can specifically be a rubber element, so that the second side 102b of the second panel 120 and the second splicing groove 320 can form a sealing effect, thereby improving the waterproofing and dustproofing effect of the protective panel assembly in this embodiment.

[0055] In some embodiments, combined with Figure 2 and Figure 3 As shown, a connecting part 221 is provided on the protrusion 220. The protrusion 220 can be connected to the first external component through the connecting part 221, so that the first set of plates 110 and the second set of plates 120 can also be connected to the first external component, thereby playing a certain protective role.

[0056] It is understood that in the embodiments of this application, both the plate 210 and the protrusion 220 disposed on the plate 210 are strip-shaped. When the splicing member 200 is disposed between the first group of plates 110 and the second group of plates 120, the length dimension of the plate 210 and the protrusion 220 matches the length dimension of the first side 101a of the first group of plates 110, and the length dimension of the plate 210 and the protrusion 220 matches the length dimension of the second side 102b of the second group of plates 120.

[0057] Furthermore, the protrusion 220 is provided with multiple connecting portions 221, and the multiple connecting portions 221 are arranged sequentially at intervals along the length direction of the protrusion 220. Through the mutual cooperation of the multiple connecting portions 221, the stability of the connection between the protrusion 220 and the first external component can be better improved. That is, the stability of the connection between the first set of plates 110 and the second set of plates 120 and the first external component through the splicing member 200 can be improved, thereby effectively playing a protective role.

[0058] It is worth mentioning that, in this embodiment of the application, the connecting part 221 is disposed on the side wall of the protrusion 220 away from the plate 210. Since the first side 101a of the first group plate 110 is embedded in the first splicing groove 310 and the second side 102b of the second group plate 120 is embedded in the second splicing groove 320, when the splicing member 200 is connected to the first external component through the connecting part 221, the first splicing groove 310 can press the first side 101a of the first group plate 110 onto the first external component, and the second splicing groove 320 can press the second side 102b of the second group plate 120 onto the first external component, thereby better realizing the installation of the first group plate 110 and the second group plate 120 on the first external component, and thus playing a better protective role.

[0059] In some embodiments, the connecting portion 221 provided on the protrusion 220 is a connecting hole, and the connecting hole penetrates the plate 210 and the protrusion 220, that is, the connecting hole is provided through the splicing member 200.

[0060] In this embodiment of the application, when connecting the splicing component 200 to the first external component, a threaded hole is provided on the first external component. During installation, the protrusion 220 on the splicing component 200 faces the first external component, and the connecting hole on the splicing component 200 is aligned with the threaded hole on the first external component. The connection between the splicing component 200 and the first external component is achieved by passing a bolt through the connecting hole and threading it into the threaded hole. Understandably, after the bolt passes through the connecting hole and is threaded into the threaded hole, the splicing component 200 is not yet fully fixedly connected to the first external component. At this time, the first side 101a of the first group plate 110 is inserted into the first splicing groove 310, and the second side 102b of the second group plate 120 is inserted into the second splicing groove 320. Then, the bolt is tightened into the threaded hole, so that the splicing component 200 is fixedly connected to the first external component. During this process, the first splicing groove 310 presses the first side 101a of the first group plate 110 against the first external component, and at the same time, the second splicing groove 320 presses the second side 102b of the second group plate 120 against the first external component. On the one hand, the splicing connection between the first group plate 110 and the second group plate 120 is realized through the splicing component 200, and on the other hand, the installation of the spliced ​​first group plate 110 and the second group plate 120 on the first external component is realized, thereby achieving a better protective effect.

[0061] When the first panel 110 or the second panel 120 is damaged or deformed due to external impact, for example, when the first panel 110 is damaged and deformed, the bolts on the splicing piece 200 can be adjusted to loosen the position between the splicing piece 200 and the first external component. This allows the first side 101a of the first panel 110 to be moved out of the first splicing groove 310, so that the first panel 110 can be disassembled and replaced in a targeted manner without replacing the second panel 120, making the operation more convenient.

[0062] It is understandable that the connecting hole provided on the protrusion 220 can be a threaded hole or a non-threaded hole, as long as it can enable the connection and installation between the splice 200 and the first external component, and there is no special limitation on this.

[0063] In some embodiments, combined with Figure 3As shown, along the thickness direction of the splicing member 200, the thickness of the first side 101a of the first group of plates 110 is not less than the depth of the first splicing groove 310. That is, the thickness of the first side 101a of the first group of plates 110 is equal to or greater than the depth of the first splicing groove 310, so that when the first side 101a of the first group of plates 110 extends into the first splicing groove 310, in the thickness direction of the splicing member 200, the first side 101a of the first group of plates 110 away from the side wall of the plate 210 can be aligned with the protrusion 220. The first splicing groove 310 is flush with the side wall of the plate 210, or the first side 101a of the first set of plates 110 is away from the side wall of the plate 210 and can protrude from the protrusion 220 away from the side wall of the plate 210. Therefore, when the splicing piece 200 is fixedly connected to the first external component through the connecting part 221, the first splicing groove 310 can better press the first side 101a of the first set of plates 110 onto the first external component, so that the first set of plates 110 can be stably connected to the first external component, thereby improving the protective effect of the first set of plates 110.

[0064] Furthermore, along the thickness direction of the splicing member 200, the thickness of the second side 102b of the second group plate 120 is not less than the depth of the second splicing groove 320. That is, the thickness of the second side 102b of the second group plate 120 is equal to or greater than the depth of the second splicing groove 320, so that when the second side 102b of the second group plate 120 extends into the second splicing groove 320, in the thickness direction of the splicing member 200, the second side 102b of the second group plate 120 away from the side wall of the plate 210 can interact with the protrusion 220. The second side 102b of the second panel 120 is flush with the side wall of the panel 210, or the second side 102b of the second panel 120 protrudes from the side wall of the protrusion 220 away from the side wall of the panel 210. Thus, when the splicing piece 200 is fixedly connected to the first external component through the connecting part 221, the second splicing groove 320 can better press the second side 102b of the second panel 120 onto the first external component, so that the second panel 120 can be stably connected to the first external component, thereby improving the protective effect of the second panel 120.

[0065] It is worth mentioning that, since the thickness of the first side 101a of the first group plate 110 is not less than the depth of the first splicing groove 310, and the thickness of the second side 102b of the second group plate 120 is not less than the depth of the second splicing groove 320, the relative position stability of the first group plate 110 and the second group plate 120 with the first external component can be better improved on the one hand, and the splicing connection stability between the first group plate 110 and the second group plate 120 can also be improved on the other hand, so that the protective plate assembly of the present application embodiment has a better protective effect.

[0066] In some embodiments, since the protective panel assembly is composed of multiple panels 100 connected by splicing members 200, and each panel 100 in the protective panel assembly can be disassembled and replaced individually, the thickness of the multiple panels 100 in the protective panel assembly can be varied. That is, the thickness of each panel 100 can be different, partially the same, or all the same. For example, the thickness of the first panel 110 and the second panel 120 can be the same or different.

[0067] It is worth mentioning that, since the multiple panels 100 in the protective plate assembly of this application embodiment can be individually disassembled and replaced, the thickness of the multiple panels 100 can be varied. Specifically, different thicknesses of the panels 100 can be designed according to the component to be protected. For example, the thickness of the panel 100 corresponding to the more vulnerable or easily damaged location of the component to be protected can be designed to be thicker, thereby enabling the panel 100 to withstand greater impact forces and effectively protect the component to be protected.

[0068] Secondly, combining Figures 3-5 As shown, this application embodiment also provides a protective device including the aforementioned protective plate assembly, thus possessing the corresponding technical effects and advantages described above. The protective device further includes a frame 400, which has an overall annular structure, allowing the protective plate assembly to be installed within the frame 400.

[0069] Furthermore, in this embodiment, the frame 400 is disposed on at least one side of the object to be protected, that is, a protective plate assembly is disposed on at least one side of the object to be protected, so that the protective plate assembly can protect the object to be protected on at least one side of the object to be protected.

[0070] Furthermore, threaded holes are provided on the frame 400, and multiple threaded holes are arranged at intervals along the circumferential direction of the frame 400. Fixing holes are provided on the side of the assembly plate 100 that is not connected to the splicing component 200, and multiple fixing holes are arranged at intervals along the side of the assembly plate 100. For example, the first side 101a of the first assembly plate 110 is connected to the splicing component 200, while the second side 102a, third side 103a, and fourth side 104a of the first assembly plate 110 are not connected to the splicing component 200. Therefore, fixing holes are provided on the second side 102a, third side 103a, and fourth side 104a of the first assembly plate 110. First fixing holes 111 are provided on the 03a and the fourth side 104a. For example, the second side 102b of the second group plate 120 is connected to the splicing component 200, while the first side 101b, the third side 103b and the fourth side 104b of the second group plate 120 are not connected to the splicing component 200. Therefore, second fixing holes 121 are provided on the first side 101b, the third side 103b and the fourth side 104b of the second group plate 120.

[0071] For example, after the first set of plates 110 and the second set of plates 120 are spliced ​​together, the protective plate assembly is placed in the frame 400. Then, bolts are passed through the first fixing hole 111 and threaded into the threaded hole on the frame 400, thereby fixing the first set of plates 110 to the frame 400. Similarly, bolts are passed through the second fixing hole 121 and threaded into the threaded hole on the frame 400, thereby fixing the second set of plates 120 to the frame 400. This achieves a better overall fixation of the protective plate assembly to the frame 400. It is understood that by fixing the protective plate assembly to the frame 400, the frame 400 can support the protective plate assembly, improving both the installation stability and strength of the protective plate assembly, resulting in better protection.

[0072] In some embodiments, a sealing element is further provided between the protective plate assembly and the frame 400. The sealing element can be a rubber element. Specifically, the rubber element can be provided on the frame 400 or on the protective plate assembly, so that when the protective plate assembly and the frame 400 are fixedly installed, the protective plate assembly and the frame 400 can clamp the sealing element, thereby enabling the sealing element to seal the gap between the protective plate assembly and the frame 400. This allows the protective device in the embodiments of this application to play a waterproof and dustproof role, resulting in better protection.

[0073] Furthermore, when the seal is installed on the frame 400, the seal can extend along the circumferential direction of the frame 400 and form a ring. When the first side 101a of the first plate 110 is connected to the splice 200, and the second side 102a, third side 103a, and fourth side 104a of the first plate 110 are not connected to the splice 200, when the guard plate assembly is installed on the frame 400, the second side 102a, third side 103a, and fourth side 104a of the first plate 110 are fixedly connected to the frame 400. During this process, the second side 102a, third side 103a, and fourth side 104a of the first plate 110 are pressed onto the frame 400 by squeezing the seal, so that while the fixed connection between the first plate 110 and the frame 400 is achieved, the seal between the first plate 110 and the frame 400 is also achieved. When the seal is installed on the first plate 110, the second side 102a, the third side 103a and the fourth side 104a of the first plate 110 are pressed onto the frame 400 by the extrusion seal, which will not be described in detail here.

[0074] In some embodiments, combined with Figures 3-5As shown, a crossbeam 410 is provided inside the frame 400. The frame 400 and / or the crossbeam 410 serve as the first external component for connection with the splicing component 200. When there are two assembly panels 100, there is one crossbeam 410. When there are more than two assembly panels 100, there are multiple crossbeams 410. The two ends of the crossbeam 410 along its length are fixedly connected to the circumferential inner sidewall of the frame 400. Preferably, the frame 400 and the crossbeam 410 are an integral structure. At least one crossbeam 410 can divide the interior of the frame 400 into multiple installation areas, wherein each installation area is used to install one assembly panel 100.

[0075] Furthermore, during the installation of the guard plate assembly onto the frame 400, for example, the splicing pieces 200 are first installed one-to-one on the crossbeam 410. Specifically, the protrusion 220 of the splicing piece 200 faces the crossbeam 410, and a threaded hole 411 is provided on the side wall of the crossbeam 410 facing the protrusion 220. The connecting part 221 on the protrusion 220 is aligned with the threaded hole 411 on the crossbeam 410, and then a bolt is passed through the connecting part 221 and threaded into the threaded hole 411 of the crossbeam 410, thereby realizing the connection between the splicing piece 200 and the crossbeam 410. After that, the first side 101a of the first set of plates 110 is inserted into the first splicing groove 310. The second side 102b of the second group plate 120 is inserted into the second splicing groove 320, and the bolts are further screwed in, so that the first splicing groove 310 presses the first side 101a of the first group plate 110 onto the crossbeam 410, and the second splicing groove 320 presses the second side 102b of the second group plate 120 onto the crossbeam 410. Then, the other sides of the first group plate 110 that are not connected to the splicing component 200 are fixedly connected to the frame 400 by bolts, and the other sides of the second group plate 120 that are not connected to the splicing component 200 are fixedly connected to the frame 400 by bolts, thereby realizing the overall installation and fixation of the guard plate assembly on the frame 400.

[0076] Understandably, when the first panel 110 is damaged or deformed, it is only necessary to disassemble and replace the first panel 110 with the frame 400 and the splicing piece 200, without having to disassemble and replace the second panel 120 with the frame 400 and the splicing piece 200, making the operation more convenient.

[0077] In some embodiments, combined with Figure 3As shown, a first support portion 412 and a second support portion 413 are also provided on the end of the crossbeam 410 near the splicing member 200. The first support portion 412 and the second support portion 413 are respectively located on both sides of the width direction of the crossbeam 410, so that when the first splicing groove 310 presses the first side edge 101a of the first group plate 110 onto the crossbeam 410, the first support portion 412 can be located on the side wall of the first group plate 110 away from the plate member 210, and the first support portion 412 can abut against the first group plate 110, thereby enabling the first support portion 412 to provide a certain support for the first side edge 101a of the first group plate 110, which can better improve the position of the first side edge 101a of the first group plate 110. This not only improves the stability of the second plate group 110 but also enhances its strength, resulting in better protection. Similarly, when the second splicing groove 320 presses the second side 102b of the second plate group 120 onto the crossbeam 410, the second support part 413 can be positioned on the side wall of the second plate group 120 away from the plate 210, and the second support part 413 can abut against the second plate group 120. This allows the second support part 413 to provide some support for the second side 102b of the second plate group 120, thereby improving the positional stability of the second side 102b of the second plate group 120 and enhancing its strength, resulting in better protection.

[0078] In some embodiments, combined with Figure 4 and Figure 5 As shown, a connecting lug 420 is also provided on the circumferential outer wall of the frame 400. Specifically, there are multiple connecting lugs 420, and the multiple connecting lugs 420 are arranged sequentially at intervals along the circumferential direction of the frame 400. A mounting hole 421 is provided on the connecting lug 420. The mounting hole 421 can be a threaded hole or a non-threaded hole.

[0079] It is understood that the protective device in this embodiment can be fixedly connected to the second external component through the mounting hole 421 on the connecting ear 420, thereby making the relative position of the protective device and the protected part more stable, thus improving the protective effect on the protected part.

[0080] Thirdly, this application embodiment also provides an electrical device including the aforementioned protective device, thus possessing the corresponding technical effects and advantages. The protective device further includes a battery pack, which is the component to be protected in this application embodiment. The protective device in this application embodiment is disposed on at least one side of the battery pack, thus effectively protecting the battery pack.

[0081] Furthermore, the electrical device in this application embodiment can be any device containing a battery pack. For example, the electrical device can be an electric vehicle. In this application embodiment, the second external component is a car. The battery pack is installed at the bottom of the electric vehicle, and a protective device of this application embodiment is provided on the side of the battery pack near the ground. Specifically, the protective device is fixedly connected to the electric vehicle through the connecting ear 420 on the frame 400. Therefore, the protective device can protect the battery pack of the electric vehicle. When the bottom of the electric vehicle is scratched or impacted, due to the isolation of the battery pack by the protective device, the scratch and impact will only act on the protective device and not on the battery pack, thereby effectively protecting the battery pack.

[0082] It is worth mentioning that when the protective device is scratched or impacted, such as when the first panel 110 is damaged or deformed, only the first panel 110 can be removed from the frame 400 and the splicing piece 200 and replaced, without having to remove the second panel 120. Therefore, the operation is more convenient and faster.
