Detailed Implementation

[0041] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

Figure 2 A schematic diagram of the cover plate assembly provided in an exemplary embodiment of this application from a second perspective. Figure 3 A partial cross-sectional view of a cover plate assembly provided for an exemplary embodiment of this application. Figure 4 An exploded view of a cover plate assembly provided for an exemplary embodiment of this application. Figure 5 A schematic diagram of the structure of a wire harness isolation plate provided in an exemplary embodiment of this application from a first perspective. Figure 6 for Figure 5 An enlarged view of point A in the diagram. (See diagram below.) Figures 1 to 6 As shown, the cover assembly 100 provided in this application embodiment may include a wire harness isolation plate 110 and a top cover assembly 120. The wire harness isolation plate 110 is provided with a mounting track 111. At least one side wall of the mounting track 111 is provided with a first locking hole 112. The top cover assembly 120 is disposed on one side of the wire harness isolation plate 110 and slides in cooperation with the mounting track 111 along a first direction (indicated by arrows C and D). The top cover assembly 120 is provided with a protrusion 121, which engages with the first locking hole 112. In this way, the top cover assembly 120 and the wire harness isolation plate 110 can be relatively fixed.

[0043] It should be understood that when it is necessary to assemble the top cover assembly 120 and the wire harness isolation plate 110, the top cover assembly 120 is slidably engaged with the mounting rail 111, and then the top cover assembly 120 is slid along the first direction, which allows the protrusion 121 to engage with the first locking hole 112, thereby completing the assembly. The entire assembly process only requires sliding the top cover assembly 120; no additional operations are needed. The assembly process is simple and convenient, effectively improving assembly efficiency. Similarly, when it is necessary to disassemble the top cover assembly 120 and the wire harness isolation plate 110, the protrusion 121 is removed from the first locking hole 112, and then the top cover assembly 120 is slid along the first direction, allowing the top cover assembly 120 to disengage from the wire harness isolation plate 110, quickly completing the disassembly and effectively improving disassembly efficiency.

[0044] In one embodiment, a first locking hole 112 is provided on one side wall of the mounting track 111, and a protrusion 121 is provided on one side of the top cover assembly 120, the protrusion 121 engaging with the first locking hole 112; or, the first locking holes 112 are provided on the opposite side walls of the mounting track 111, and the protrusions 121 are provided on the opposite side walls of the top cover assembly 120, the protrusions 121 on both sides engaging with the first locking holes 112 on both sides respectively.

[0045] In one embodiment, there are multiple first card holes 112, and the number of protrusions 121 is the same as the number of first card holes 112, and they correspond one-to-one.

[0046] like Figure 5 As shown, the wire harness isolation plate 110 has mounting rails 111 at both ends along the second direction (indicated by arrows E and F), and the two mounting rails 111 are distributed in parallel; correspondingly, combined with Figure 2 The top cover assembly 120 slides with two mounting rails 111 on opposite sides along the second direction. This makes it less likely for the top cover assembly 120 to shift or tilt during the sliding engagement, thereby improving the smoothness and stability of the assembly process between the top cover assembly 120 and the wire harness isolation plate 110.

[0047] like Figure 5 and Figure 6As shown, the mounting track 111 includes a first end 1111 and a second end 1112 arranged opposite to each other. There are multiple first locking holes 112, some of which are located at the first end 1111 and others at the second end 1112. Correspondingly, the number of second locking holes 1222 is the same as the number of first locking holes 112, and they correspond one-to-one. Similarly, the number of protrusions 121 is the same as the number of first locking holes 112, and they correspond one-to-one. Thus, after the multiple protrusions 121, the multiple first locking holes 112, and the multiple second locking holes 1222 are engaged in a one-to-one correspondence, the opposite ends of the top cover assembly 120 are fixed to the opposite ends of the wire harness isolation plate 110, which improves the assembly stability between the top cover assembly 120 and the wire harness isolation plate 110.

[0048] Figure 7 A schematic diagram of the top cover body provided in an exemplary embodiment of this application from a first perspective. Figure 8 A schematic diagram of the top cover body provided in an exemplary embodiment of this application from a second perspective. Figure 9 for Figure 8 An enlarged view of point B in the middle. (See diagram below.) Figure 4 , Figures 7 to 9 As shown, the top cover assembly 120 may include a top cover body 122, the top cover body 122 is provided with a mounting hole 1221, and at least one side wall of the mounting hole 1221 is provided with a second snap hole 1222.

[0049] In practical applications, the top cover body 122 is slidably connected to the mounting rail 111, and the part with the mounting hole 1221 is slidably engaged with the mounting rail 111. The extension direction of the mounting hole 1221 is parallel to the extension direction of the mounting rail 111. The second locking hole 1222 is correspondingly connected to the first locking hole 112. In this way, the second locking hole 1222 and the first locking hole 112 can be simultaneously engaged by the protrusion 121 to achieve the aforementioned fixing effect.

[0050] Figure 10 This is a schematic diagram of the structure of an elastomer provided for an exemplary embodiment of this application. (In conjunction with...) Figure 4 and Figure 10 The top cover assembly 120 may also include an elastic body 123. The surface of the elastic body 123 is provided with the aforementioned protrusion 121. After the top cover body 122 and the mounting track 111 are assembled, the elastic body 123 can be engaged with the mounting hole 1221.

[0051] Specifically, as the elastic body 123 gradually extends into the mounting hole 1221, the protrusion 121 on the elastic body 123 will be correspondingly engaged in the first locking hole 112 and the second locking hole 1222, thereby fixing the elastic body 123, the top cover body 122 and the wire harness isolation plate 110 relatively.

[0052] It should be noted that during the assembly process of the elastomer 123 into the mounting hole 1221, it is compressed by the inner wall of the mounting hole 1221. When the protrusion 121 is aligned with the first locking hole 112 and the second locking hole 1222, the protrusion 121 can automatically lock into the first locking hole 112 and the second locking hole 1222 with the help of the restoring force of the elastomer 123. The assembly process is convenient and quick, thereby effectively improving the overall assembly efficiency.

[0053] In one embodiment, the number of the first card hole 112, the second card hole 1222, and the protrusion 121 are the same, and they correspond one-to-one.

[0054] In one embodiment, the elastomer 123 is a spring sheet structure, which is lightweight and facilitates rapid assembly.

[0055] like Figure 10 As shown, the elastomer 123 has a U-shaped structure and includes a connecting end 1231 and an opening end 1232 that are disposed opposite to each other. At least one end of the mounting hole 1221 (which may be one end of the mounting hole 1221 or both opposite ends of the mounting hole 1221) is provided with a mounting port 1223.

[0056] In the actual process of assembling the elastomer 123 into the mounting hole 1221, the connecting end 1231 first slides into the mounting hole 1221 through the mounting opening 1223. After the elastomer 123 is fully inserted into the mounting hole 1221, the open end 1232 of the elastomer 123 mates with the mounting opening 1223, and the outer wall of the open end 1232 abuts against the inner wall of the mounting opening 1223. In this way, it can effectively prevent the elastomer 123 from detaching from the mounting hole 1221 through the mounting opening 1223 without the action of external force after assembly, thereby improving the assembly reliability of the elastomer 123 and ensuring that the elastomer 123 can continuously fix the top cover body 122 and the wire harness isolation plate 110.

[0057] It should be noted that in the initial state where the elastomer 123 has not entered the mounting hole 1221, the opening size of the opening end 1232 is larger than the opening size of the mounting port 1223. In this way, when the open end 1232 mates with the mounting port 1223, the open end 1232 is in a compressed state. Under the action of the restoring force of the open end 1232, the outer wall of the open end 1232 can apply pressure to the inner wall of the mounting port 1223, making the open end 1232 and the mounting port 1223 fit more tightly. On the one hand, the tight fit between the open end 1232 and the mounting port 1223 can help the elastomer 123 maintain a relatively fixed state in the mounting hole 1221, avoiding the elastomer 123 from shaking in the mounting hole 1221, and improving the assembly stability of the elastomer 123 in the mounting hole 1221. On the other hand, the tight fit between the open end 1232 and the mounting port 1223 can make it less likely for the open end 1232 to slide relative to the mounting port 1223 after it is assembled into the mounting port 1223, thereby further preventing the elastomer 123 from detaching from the mounting port 1223 from the mounting hole 1221.

[0058] It is worth noting that, compared to the scheme where the connecting end 1231 is inserted first to mate with the mounting port 1223, the embodiment in this application where the connecting end 1231 is inserted first to mate with the mounting port 1223 also facilitates the subsequent rapid disassembly of the elastomer 123. Specifically, when it is necessary to remove the elastomer 123 from the mounting hole 1221, the opening end 1232 is pressed (to compress and reduce the opening size of the opening end 1232), creating a gap between the outer wall of the opening end 1232 and the inner wall of the mounting port 1223. Then, the elastomer 123 can be removed from the mounting hole 1221 by pulling the opening end 1232, making the disassembly process convenient and quick. In addition, pressing the opening end 1232 can also help some of the protrusions 121 disengage from the first locking hole 112 and the second locking hole 1222, thereby facilitating the subsequent removal of the elastomer 123 from the mounting hole 1221 and further improving the disassembly efficiency.

[0059] like Figure 10 As shown, the outer surface of the protrusion 121 is an arc-shaped surface. In this way, the arc-shaped surface can play a guiding role in the process of the protrusion 121 being inserted into the first locking hole 112 and the second locking hole 1222, which facilitates the rapid insertion of the protrusion 121 and effectively improves the assembly efficiency.

[0060] Figure 11 This is a schematic diagram of the structure of a wire harness isolation plate provided as an exemplary embodiment of this application, viewed from a second perspective. Figure 11 As shown, one side wall of the mounting track 111 is provided with a guide groove 113, which extends along a first direction (the direction indicated by arrows C and D).

[0061] Combination Figures 7 to 9 The top cover body 122 may include a cover plate 1224 and a guide body 1225. A guide sidewall 1226 protrudes from the edge of the cover plate 1224. The guide body 1225 is connected to the guide sidewall 1226 and slides with the mounting track 111. The guide sidewall 1226 slides with the guide groove 113. It should be understood that the mating structure of the guide sidewall 1226 and the guide groove 113 can guide and limit the sliding of the guide body 1225 in the mounting track 111, preventing the guide body 1225 from deviating from the mounting track 111 during sliding.

[0062] It should be noted that the aforementioned mounting hole 1221 is disposed in the guide body 1225 along the first direction. After the guide body 1225 and the mounting track 111 are slidably assembled, the second locking hole 1222 on the side wall of the mounting hole 1221 can communicate with the corresponding first locking hole 112 without the need for additional alignment steps, which effectively improves the overall assembly efficiency.

[0063] like Figure 6 and Figure 11 As shown, the guide groove 113 and the first locking hole 112 are respectively located on opposite sides of the mounting track 111. In this way, during the manufacturing process of the guide groove 113, there will be no interference between the guide groove 113 and the first locking hole 112, which facilitates the manufacturing process.

[0064] The battery provided in this application embodiment may include a battery cell and the cover plate assembly 100 described in the foregoing embodiment, and the wire harness isolation plate 110 is connected to the top of the battery cell.

[0065] It should be understood that the battery has all the functions of the cover assembly 100, and the beneficial effects of the battery can be referred to the beneficial effects of the aforementioned cover assembly 100.
