In this embodiment, the locking assembly 5 includes a first locking structure 5a, which includes: a slide rail 51, fixed to the cover 11 of the driving cabin 202 near the mobile device 20; a slider 52, detachably slidably connected to the slide groove 511 of the slide rail 51, the slide groove 511 having a first supporting surface 512 for supporting the slider 52, the slider 52 having a first surface 521 facing the first supporting surface 512, and a second surface 522 opposite to the first surface 521, the first surface 521 is provided with a first receiving portion 523 having a receiving groove 5231, the slider 52 also has a second side surface 524 that passes through the first surface 521, the second surface 522, the first surface 521 and the second surface 522, and a first limiting hole 525 of the first receiving portion 523, the first limiting hole 525 is connected to the receiving groove 5231, the first surface 521 is also provided with a first limiting hole 525 on opposite sides of the first limiting hole 525 The two limiting ribs 526 of the threaded rod 53 are arranged at one end in the receiving groove 5231, and the threaded rod 53 can rotate relative to the slider 52 through the first limiting hole 525 and the gap between the two limiting ribs 526; the first locking member 54a is sleeved on the threaded rod 53; and the handle 55a is threadedly connected to the threaded rod 53; wherein the two limiting ribs 526 cooperate with each other to limit the threaded rod 53, preventing the threaded rod 53 from rotating relative to the limiting ribs 526, so that the handle The hand 55a, the first locking member 54a and the threaded rod 53 are accommodated in the slide groove 511; when the threaded rod 53 is subjected to a torque away from the first support surface 512, the threaded rod 53 can rotate relative to the slider 52, so that the handle 55a, the first locking member 54a and part of the threaded rod 53 are rotated outside the slide groove 511; when the first locking member 54a is arranged outside the slide groove 511, the first locking member 54a can fix the cover plate 11 to the trunk 201 through the handle 55a.

[0129] In this embodiment, the slide rail 51 is fixed to the cover plate, and the slider 52 is detachably slidably connected to the slide groove 511 of the slide rail 51. One end of the threaded rod 53 is disposed in the receiving groove 5231 of the slider 52. The other end of the threaded rod 53 is sleeved with a first locking member 54a and a handle 55a. The handle 55a is threadedly connected to the threaded rod 53. Driven by the handle 55a, the threaded rod 53 and the first locking member 54a can move relative to the slider 52. Driven by the handle 55a, the slider 52 can move relative to the slide rail 51 within the slide groove 511. The handle 55a can rotate circumferentially relative to the threaded rod 53 to move within the threaded area of ​​the threaded rod 53, thereby changing the position of the first locking member 54a. The handle 55a can drive the threaded rod 53 and the first locking member 54a to move and be received in the slide groove 511, thereby achieving the storage of the handle 55a, the threaded rod 53, and the first locking member 54a. The handle 55a can drive the threaded rod 53 and the first locking member 54a to move outside the slide groove 511. In this state, the position of the slider 52 in the slide groove 511 can be adjusted, and the handle 55a can be rotated so that the handle 55a can abut and drive the first locking member 54a to abut against the tail box of the mobile device, thereby fixing the cover to the tail box of the mobile device.

[0130] In this embodiment, the two limiting ribs 526 can cooperate with each other to limit the threaded rod 53. When the handle 55a, the threaded rod 53, and the first locking member 54a are received in the chute 511, the threaded rod 53 is clamped between the two limiting members to prevent the threaded rod 53 from rotating relative to the limiting members. This allows the handle 55a, the first locking member 54a, and the threaded rod 53 to be received in the chute 511 without being dislodged from the chute 511, facilitating the storage of the first locking structure 5a. Specifically, when the two limiting ribs 526 are disposed on the opposing surfaces of the threaded rod 53, frictional resistance between the threaded rod 53 and the opposing surfaces of the two limiting ribs 526 can be used to limit the threaded rod 53, so that the handle 55a, the first locking member 54a, and the threaded rod 53 can be received in the chute 511 without being dislodged from the chute 511. When the threaded rod 53 is subjected to a force directed away from the first support surface 512, and the force is greater than the frictional resistance of the two opposing surfaces of the two limiting ribs 526, the threaded rod 53 can compress the two limiting ribs 526, causing the two limiting ribs 526 to deform in opposite directions, thereby allowing the threaded rod 53 to disengage from the two limiting ribs 526, allowing the handle 55a, the first locking member 54a, and a portion of the threaded rod 53 to rotate out of the sliding groove 511. Specifically, the threaded rod 53 includes a connected horizontal rod 531 and a vertical rod 532. The horizontal rod 531 is disposed in the receiving groove 5231. The vertical rod 532 is threaded. The limiting rib 526 satisfies at least one of the following conditions: in the first condition, a protrusion 5261 is provided on the surface of each limiting rib 526 facing the other limiting rib 526, and the distance between the two protrusions 5261 (please refer to D1 in Figure 8) is smaller than the diameter of the longitudinal rod 532 (please refer to D2 in Figure 7); in the second condition, an avoidance groove 5262 is provided on the surface of each limiting rib 526 facing the other limiting rib 526, and the distance between the bottom walls of the two avoidance grooves 5262 (please refer to D3 in Figure 9) is greater than the diameter between the longitudinal rods 532.

[0131] In this embodiment, the first locking structure 5a secures the cover plate 11 to the trunk 201. Specifically, the first locking member 54a of the first locking structure 5a abuts against and hooks onto the side 2012 of the trunk 201, maintaining the first locking structure 5a and the side 2012 in relative fixation, thereby securing the cover plate 11 to the trunk 201. The side 2012 is mounted on the edge of the trunk 201 and extends into the interior of the trunk 201, forming a hook-shaped structure with an opening facing the bottom wall of the trunk 201, thereby facilitating a secure connection between the side 2012 and the first locking member 54a.

[0132] Optionally, a decorative block 518 is installed at one end of the slide rail 51 for decoration, and a plug 519 is installed at the other end of the slide rail 51 to limit the slide groove 511 and play a role in buffering, waterproofing, etc.

[0133] Please refer to Figures 6-11. Figure 11 is a schematic diagram of the structure of the first locking member in Figure 6. In this embodiment, the first locking member 54a includes a sleeve portion 541a that sleeves onto the threaded rod 53, an extension portion 542a connected to the sleeve portion 541a, and a first locking portion 543a that is bent and connected to the extension portion 542a. The end of the first locking portion 543a facing away from the extension portion 542a is used for clamping and fixing. In the alignment direction of the first locking member 54a and the handle 55a, the length of the first locking portion 543a (see L1 in Figure 11) is less than the length of the sleeve portion 541a (see L2 in Figure 11). The extension portion 542a is inclined compared to the sleeve portion 541a and is inclined in the direction away from the handle 55a, and the end face of the first locking portion 543a away from the handle 55a is farther away from the handle 55a than the end face of the sleeve portion 541a away from the handle 55a, so that the force arm of the first locking portion 543a is shorter when fixing the tail box of the mobile device, which is beneficial to reducing the torque exerted on the first locking portion 543a, so that the first locking portion 543a can withstand a greater extrusion force to improve the fixing strength.

[0134] Optionally, a gap is provided between the two limiting ribs 526 and the second side surface 524, forming a stepped surface at the gap. When the buffer member 56 is engaged with the handle 55a and the first locking member 54a, the bearing portion is engaged with the stepped surface, and the buffer member 56 is used to abut the sleeve portion 541a against the two limiting ribs 526 to limit the sleeve portion 541a between the bearing surface and the slide rail 51.

[0136] In this embodiment, the first limiting rail 515 and the second limiting rail 516 form an anti-drop limit for the slider 52, preventing the slider 52 from falling out of the slide groove 511. After the slider 52 is installed in the slide groove 511, the handle 55b can be used to drive the slider 52 to move within the slide groove 511 relative to the slide rail 51.

[0137] In this embodiment, the second locking structure 5b secures the cover plate 11 to the trunk 201. Specifically, the second locking member 54b of the second locking structure 5b abuts against and hooks onto the side 2012 of the trunk 201, maintaining the second locking structure 5b and the side 2012 in relative fixation, thereby securing the cover plate 11 to the trunk 201. The side 2012 is mounted on the edge of the trunk 201 and extends into the interior of the trunk 201, forming a hook-shaped structure with an opening facing the bottom wall of the trunk 201, thereby facilitating a secure connection between the side 2012 and the second locking member 54b.

Optionally, the connecting body 312 and the first clamping portion 311 are an integral structure or a split structure. This embodiment is only schematically described as an integral structure of the connecting body 312 and the first clamping portion 311. Further optionally, the material of the first connector 31a includes but is not limited to plastic, carbon fiber, aluminum alloy, magnesium alloy, etc.

[0152] The first clamping portion 311 provided in this embodiment is composed of three parts: a first clamping post 3111, a first bent post 3112, and a second bent post 3113. The first clamping post 3111 is straight, and there are two first bent posts 3112 and two second bent posts 3113. The two first bent posts 3112 are bent and connected to opposite sides of the first clamping post 3111, and the second bent post 3113 is bent and connected to the side of each first bent post 3112 facing away from the first clamping post 3111. Optionally, the angle between the first bent post 3112 and the first clamping post 3111 is not less than 90°, and the angle between the first bent post 3112 and the second bent post 3113 is not greater than 90°. The above content can also be understood as the overall shape of the first clamping portion 3111 is not straight, but rather a curved shape that has been bent twice. The bent first clamping portion 311 can firstly increase the clamping size and clamping area of ​​the first clamping portion 311. When the first clamping portion 311 is inserted into the first clamping hole 211 of the first profile 21, the clamping contact surface between the first clamping portion 311 and the first clamping hole 211 is increased, thereby improving the clamping effect. Secondly, because the bending can change the direction of the first clamping portion 311, the clamping direction can be increased, and more degrees of freedom can be limited between the first connecting member 31a and the first profile 21, further improving the clamping effect. In addition, this embodiment also arranges the two second bent columns 3113 close to each other, rather than separating the two second bent columns 3113 from each other, which can reduce the overall size of the first clamping portion 311, thereby reducing the overall size of the first connecting member 31a and the first profile 21, and achieving miniaturization of the first clamping portion 311 and the first profile 21.

[0153] Optionally, the shape and size of the first clamping portion 311 are adapted to match the shape and size of the first clamping hole 211. As can be seen from the above, designing the first clamping portion 311 into a twice-bent shape can improve the clamping effect. This embodiment also allows the shape and size of the first clamping portion 311 to match the shape and size of the first clamping hole 211. In other words, the shape of the first clamping hole 211 is also correspondingly designed to be twice-bent, which can further improve the clamping effect between the first connecting member 31a and the first profile 21. In addition to the shape, the size of the first clamping portion 311 can also be adapted to match the size of the first clamping hole 211, and the size of the first clamping column 3111, the size of the first bent column 3112, and the size of the second bent column 3113 can each be adapted to the hole wall size of the first clamping hole 211, thereby further improving the clamping effect. Optionally, the first clamping column 3111 , the first bending column 3112 , and the second bending column 3113 of the first clamping portion 311 may abut against a hole wall of the first clamping hole 211 .

[0154] Optionally, the connecting body 312 is provided with a fourth through hole 3121, and the fourth through hole 3121 passes through one side of the connecting body 312 where the first clamping portion 311 is provided, and the side of the connecting body 312 opposite to the first clamping portion 311 is provided. The fourth through hole 3121 is used to allow the first fastener to pass through and be fastened to the first fixing member 217 of the first profile 21. The fourth through hole 3121 is provided in the space formed by the first clamping column 3111, the first bending column 3112, and the second bending column 3113.

[0155] Furthermore, after the first fastener is installed in the fourth through hole 3121, a rubber plug is inserted into the fourth through hole 3121. This not only provides a waterproof seal to prevent the first fastener from rusting, but also conceals the first fastener and the fourth through hole 3121 for an aesthetically pleasing appearance. Rubber plugs can also be used in other through holes where fastening structures are required to be inserted to protect the fastening structures and improve the appearance.

[0156] Optionally, the connecting body 312 includes a first side 301 and a second side 302 arranged opposite to each other, and a third side 303 and a fourth side 304 arranged opposite to each other between the first side 301 and the second side 302, the first side 301 is bent and connected to the third side 303, a first clamping portion 311 is provided on the first side 301 and the third side 303, the second side 302 is bent and connected to the fourth side 304, and a fourth through hole 3121 is provided on the second side 302 and the fourth side 304.

[0157] In addition, in this embodiment, fourth through holes 3121 may be respectively defined on the second side 302 and the fourth side 304, and two first fasteners may be used to respectively secure the first connecting member 31a to the two first profiles 21. For example, one first fastener may secure the first profile 21 on the first side 301 to the first connecting member 31a through the fourth through hole 3121 on the second side 302, and another first fastener may secure the first profile 21 on the third side 303 to the first connecting member 31a through the fourth through hole 3121 on the fourth side 304, thereby securing the first connecting member 31a to the plurality of first profiles 21.

[0158] In this embodiment, the first connecting member 31a is used to first fasten a first fastener to a first fixing member 217 of a first profile 21 through a fourth through hole 3121, and the end of a first fastener is arranged in the first avoidance groove 3125; the first connecting member 31a is also used to fasten another first fastener to a first fixing member 217 of another first profile 21 through another fourth through hole 3121, and the end of the other first fastener is arranged in the first avoidance groove 3125.

[0159] Furthermore, in this embodiment, the first avoidance groove 3125 includes a first sub-portion 3125a axially arranged along one fourth through-hole 3121, and a second sub-portion 3125b axially arranged along the other fourth through-hole 3121. The first sub-portion 3125a communicates with the second sub-portion 3125b. The end of one first fastener is disposed within the first sub-portion 3125a, and the end of the other first fastener is disposed within the second sub-portion 3125b. The first avoidance groove 3125 has a curved shape, with the end of one first fastener disposed within the first sub-portion 3125a. This allows the other first fastener to pass through the other fourth through-hole 3121 and enter the second sub-portion 3125b without being affected by the first fastener located within the first sub-portion 3125a, further preventing interference between the two first fasteners.

[0160] A first weight-reducing groove 3141 is provided on the first bottom surface 314 of the first connecting member 31b to reduce the weight of the first connecting member 31b. At the same time, this embodiment can also be provided with a plurality of reinforcement groups 315 arranged along the extension direction of the first weight-reducing groove 3141, thereby improving the structural strength of the first connecting member 31b. This embodiment is only schematically illustrated with three reinforcement groups 315. In addition, each reinforcement group 315 includes two first reinforcement members 3151, and each first reinforcement member 3151 simultaneously connects the side walls and bottom walls on opposite sides of the first weight-reducing groove 3141. The two first reinforcement members 3151 are tilted and arranged on the side walls of the first weight-reducing groove 3141, and the two first reinforcement members 3151 are arranged axially symmetrically, which can further improve the structural strength of the first connecting member 31b, so that the first connecting member 31b has a higher structural strength while reducing weight.

[0161] Optionally, the first connector 31b has a fifth side 305 for connecting to the first profile 21 on one side of the cover plate 11, and a sixth side 306 for connecting to the first profile 21 on an adjacent side of the cover plate 11. The first connector 31b has a third fixing hole 316 extending through the outer peripheral side 307 of the first connector 31b and the fifth side 305. The third fixing hole 316 communicates with the first weight-reducing groove 3141 and is closer to the fifth side 305 than to the sixth side 306. The first connector 31b has multiple sides, one of which is the fifth side 305 for connecting to the first profile 21 on one side of the cover plate 11, and the other is the sixth side 306 for connecting to the first profile 21 on the adjacent side of the cover plate 11. Therefore, the fifth side 305 and the sixth side 306 are also adjacent to each other. The exterior surface of the first connector 31b may be referred to as the outer peripheral side 307. The first connecting member 31b is provided with a third fixing hole 316, which extends through the outer circumference 307 and the fifth side 305 of the first connecting member 31b. The third fixing hole 316 communicates with the first weight-reducing groove 3141. Subsequently, a screw is passed through the third fixing hole 316 on the outer circumference 307 of the first connecting member 31b, the first weight-reducing groove 3141, and the third fixing hole 316 on the fifth side 305. Finally, the screw passes through the third fixing hole 316 to securely connect with the first profile 21, thereby securing the first connecting member 31b to the first profile 21. This embodiment allows the third fixing hole 316 to be closer to the fifth side 305, thereby reducing the length of the third fixing hole 316 and making it easier for the screw to subsequently pass through the third fixing hole 316.

[0162] Optionally, the outer side 307 of the first connecting member 31b includes a first outer side surface 3071 that is bent and connected to the sixth side 306, and a second outer side surface 3072 that is bent and connected to the fifth side 305. The second outer side surface 3072 is arcuate. The outer side 307 includes the first outer side surface 3071 and the second outer side surface 3072, which are connected to each other. The first outer side surface 3071 is bent and connected to the sixth side 306, and the second outer side surface 3072 is bent and connected to the fifth side 305. In this embodiment, the second outer side surface 3072 can be arcuate, and the third fixing hole 316 can be provided on the second outer side surface 3072. Since the first connecting member 31b is elongated, providing the third fixing hole 316 on the arcuate second outer side surface 3072 opposite the fifth side 305 can reduce the length of the third fixing hole 316, facilitating screw insertion and tightening.

[0163] In summary, due to the presence of the first outer side surface 3071 and the second outer side surface 3072, the first connecting member 31b is elongated. Therefore, a shorter third fixing hole 316 can be provided, but a longer fourth fixing hole 317 cannot be provided. This not only results in the lack of longer screws, but also makes it difficult to secure the first profile 21. Therefore, in this embodiment, a second avoidance groove 3152 is provided in the first reinforcement member 3151, allowing the screw to pass directly through the sixth side 306 via the second avoidance groove 3152 in the first weight-reducing groove 3141, thereby reducing the difficulty of tightening the screw.

[0164] Please refer to Figure 1, Figure 29-Figure 35, Figure 29 is a structural schematic diagram of the second profile in Figure 2; Figure 30 is a structural schematic diagram of the second profile in Figure 29 from another perspective; Figure 31 is a schematic diagram of the end face of the second profile in Figure 29; Figure 32 is a structural schematic diagram of the second connecting member in Figure 2 connecting the first profile and the second profile; Figure 33 is a structural schematic diagram of the second connecting member in Figure 32; Figure 34 is a structural schematic diagram of the second connecting member in Figure 33 from another perspective; Figure 35 is a schematic diagram of the bottom surface structure of the second connecting member in Figure 32. In this embodiment, the profile assembly 2 further includes: a second profile 22, the second profile 22 having a second through hole 221 and a first mounting groove 212 arranged at intervals, the second profile 22 wraps the edge of the cover plate 11 close to the adjacent other cover plate 11 through the first mounting groove 212, a first partition 222 is provided in the second through hole 221, the first partition 222 divides the second through hole 221 into a second snap-fit ​​hole 2211 and a weight-reducing hole 2212, the first partition 222 is provided with a third locking portion 223 located in the weight-reducing hole 2212; and the connecting assembly 3 further includes In summary: the second connecting member 32, one side of the second connecting member 32 is provided with a second clamping portion 321 and an assembly part 322 arranged at intervals, the second clamping portion 321 is used to be inserted into the second clamping hole 2211, and the assembly part 322 is used to be inserted into the weight reduction hole 2212, the height of the second clamping portion 321 is greater than the height of the assembly part 322, and the other side of the second connecting member 32 is provided with a first clamping portion 311, and the second connecting member 32 is connected to the first profile 21 and the second profile 22 on the same cover plate 11 through the first clamping portion 311, the second clamping portion 321 and the assembly part 322.

[0165] The materials of the second profile 22 include, but are not limited to, carbon fiber, iron alloy, aluminum alloy, magnesium alloy, etc. The end surface of the second profile 22 has two spaced-apart hole structures: a second through-hole 221 and a first mounting slot 212. The two hole structures extend along the length of the second profile 22. The two hole structures are separated by an inner wall. The first mounting slot 212 is a hole structure with side openings, so the periphery of subsequent components can enter the first mounting slot 212 through the opening and be fixed therein. The second through-hole 221 is a closed hole 221 that only passes through the two opposite end surfaces of the second profile 22. The second through-hole 221 is used to mount other components of the second profile 22. For example, a first partition 222 can be provided within the second through-hole 221. The first partition 222 connects the top and bottom walls of the second profile 22, thereby further dividing the second through-hole 221 into two hole structures: a second snap-fit ​​hole 2211 and a weight-reducing hole 2212.

[0166] In addition, a third locking portion 223 may be provided on one side of the first partition 222 near the weight-reducing hole 2212. The third locking portion 223 is located within the weight-reducing hole 2212. The third locking portion 223 may subsequently be locked with the second connector 32 to secure the second connector 32 to the second profile 22. Providing the third locking portion 223 on the first partition 222 not only simplifies the structure and optimizes the design, effectively utilizing the space within the weight-reducing hole 2212, but also improves the structural strength of the second profile 22, prevents cracking of the second profile 22, and increases the service life of the second profile 22.

[0167] Optionally, the third locking portion 223 has a locking hole 2231 extending through a surface of the third locking portion 223 facing away from the first partition 222, exposing the locking hole 2231. The third locking portion 223 is arranged axially symmetrically. The locking holes 2231 may be defined in the third locking portion 223 and extend through opposite end surfaces of the second profile 22. The locking holes 2231 can subsequently be used for locking engagement with the second connector 32.

[0168] In addition, the threaded hole also penetrates the side surface of the third locking portion 223 away from the first partition portion 222 to expose the locking hole 2231. It can also be understood that the locking hole 2231 is not a hole closed on all sides, but has an open hole structure. The locking hole 2231 penetrates the side surface of the third locking portion 223 away from the first partition portion 222, which can facilitate the subsequent deformation of the third locking portion 223, thereby preventing the third locking portion 223 from breaking or being damaged, and improving the service life of the third locking portion 223.

[0169] Optionally, at least one of the outer third sidewall 226 of the second profile 22 and the bottom wall of the widened groove 2220 has a molding groove 2221. In this embodiment, the molding groove 2221 can be provided on the outer third sidewall 226 of the second profile 22. The molding groove 2221 facilitates drainage and exhaust during the hemming process, allowing water or gas to be quickly discharged from the second profile 22 through the molding groove 2221. In other embodiments, the molding groove 2221 can also be provided on the bottom wall of the widened groove 2220. The molding groove 2221 on the widened bottom wall is primarily used for drainage and exhaust, allowing internal water, gas, etc. to be quickly discharged from the second profile 22 through the molding groove 2221.

[0170] Optionally, the first wall 224 includes a first sub-wall 2241 and a second sub-wall 2242 disposed on opposite sides of the second engaging groove 231. The first sub-wall 2241 corresponds to the second through-hole 221, and the second sub-wall 2242 corresponds to the first mounting groove 212. The distance between the first sub-wall 2241 and the second wall 225 is smaller than the distance between the second sub-wall 2242 and the second wall 225. The first wall 224, i.e., the top wall, may include a first sub-wall 2241 and a second sub-wall 2242 disposed on opposite sides of the second engaging groove 231. The first sub-wall 2241 corresponds to the second through-hole 221, and a portion of the second sub-wall 2242 corresponds to the second through-hole 221, while the remaining portion corresponds to the first mounting groove 212. In this embodiment, the distance between the first sub-wall 2241 and the second wall 225 is smaller than the distance between the second sub-wall 2242 and the second wall 225. The second waterproof structure 42 is not only sealed to the second profile 22, but also to adjacent components of the second profile 22 (e.g., connectors, second profile 22, etc.). Furthermore, the second profile 22 and connectors are also capable of relative rotation. Therefore, by controlling the heights of the first sub-wall 2241 and the second sub-wall 2242, this embodiment eliminates indentations in the second waterproof structure 42, improves the appearance of the seal, and enhances the squeeze-to-position effect.

[0171] The second connector 32 also connects the first and second profiles 21, 22 on adjacent sides of the cover plate 11, ensuring a smooth connection and transition around the perimeter of the cover plate 11. The first and second profiles 21, 22 will later be provided with second snap-fit ​​grooves 231 to accommodate the second snap-fit ​​ribs 422 protruding from the second waterproof structure 42, thereby connecting the first and second profiles 21, 22 to the second waterproof structure 42. The first and second profiles 21, 22 also have assembly holes and lightening holes. The second snap-fit ​​portion 321 can be inserted into the assembly holes, and the assembly part 322 can be inserted into the lightening holes. Since the sealing groove is located within the lightening holes, the height of the lightening holes at that location is reduced. Optionally, the second snap-fit ​​portion 321 and the assembly part 322 are plate-shaped. Optionally, the second snap-fit ​​portion 321 and the assembly part 322 are provided with guide ramps on the sides facing away from the second connector 32 to facilitate the insertion of the second snap-fit ​​portion 321 and the assembly part 322 into the first and second profiles 21, 22.

[0172] This embodiment can make the height of the second clamping portion 321 greater than the height of the assembly part 322. The second clamping portion 321 with a higher height can be used for subsequent insertion into an assembly hole with a higher height, and the assembly part 322 with a lower height can be used for subsequent insertion into a weight-reducing hole with a lower height, that is, the assembly part 322 is located below the second clamping groove 231 in the weight-reducing hole and will not occupy other space in the weight-reducing hole, thereby saving space in the weight-reducing hole, reducing the size of the first profile 21 and the second profile 22, and effectively utilizing space. The first profile 21 and the second profile 22 can be made narrower, so that the second connecting part 32 can be better adapted to the new first profile 21 and the second profile 22, thereby improving the adaptation effect of the second connecting part 32 with the first profile 21 and the second profile 22.

[0173] Optionally, the materials of the first profile 21 and the second profile 22 include but are not limited to plastic, carbon fiber, aluminum alloy, magnesium alloy, etc.

[0174] Optionally, the second connector 32 has a top side and a bottom side. The top side is the side of the second connector 32 facing away from the trunk 201 when the foldable cover 10 is subsequently applied to the second connector 32 and the foldable cover 10 is placed on the trunk 201 and is in the unfolded state. Conversely, the side of the second connector 32 closer to the trunk 201 is the bottom side. In this embodiment, a recessed accommodating groove 323 may be formed on the top side. The accommodating groove 323 may be used to accommodate the second waterproof structure 42 connected to the first and second profiles 21, 22. The second waterproof structure 42 may protrude from the ends of the first and second profiles 21, 22. Therefore, the protruding portion may be disposed in the accommodating groove 323 of the second connector 32, thereby preventing the first and second profiles 21, 22 from protruding from the second connector 32, thereby allowing the first and second profiles 21, 22 to be arranged flush.

[0175] Optionally, a receiving groove 324 communicating with the receiving groove 323 is provided on the sidewall of the receiving groove 323, and the receiving groove 324 is used to accommodate the end of the second waterproof structure 42. The sidewall of the receiving groove 323 may also be provided with a receiving groove 324 communicating with the receiving groove 323, and the end of the second waterproof structure 42 may be inserted into the receiving groove 324, thereby preventing the end of the second waterproof structure 42 from warping or flanging, and also effectively protecting the second waterproof structure 42.

[0176] Optionally, a drainage groove 325 is provided on the side of the second connecting member 32, connecting the receiving groove 324 with the receiving groove 323. A drainage groove 325 can also be provided on the side to connect the receiving groove 324 with the waterproof groove. When water falls on the top surface, the water will flow through the receiving groove 323 and the receiving groove 324 to the drainage groove 325, and then flow through the drainage groove 325 to the cover of the second connecting member 32, effectively diverting the water to the outside of the second connecting member 32.

[0177] Please refer to Figures 36 to 41, Figure 36 is a structural schematic diagram of the third profile in Figure 2; Figure 37 is a structural schematic diagram of the end face of the third profile in Figure 36; Figure 38 is a structural schematic diagram of the third connecting member in Figure 2; Figure 39 is a structural schematic diagram of the third connecting member in Figure 38 from another perspective; Figure 40 is a structural schematic diagram of the bottom surface of the third connecting member in Figure 38; Figure 41 is a local enlarged schematic diagram of point III in Figure 2. In this embodiment, the profile assembly 2 also includes: a third profile 23, the third profile 23 is located between the second profile 22 located at the edge of the cover 11 close to the driving compartment 202 and the second profile 22 located at the edge of the cover 11 located in the middle, one side of the third profile 23 is bent to form a second arc-shaped snap-in groove 231, the second snap-in groove 231 extends along the extension direction of the third profile 23, and the opening width of the second snap-in groove 231 is smaller than the diameter of the second snap-in groove 231; the connecting assembly 3 also includes: a third connecting member 33, the third connecting member 33 has a plug-in surface 331 for plugging into the third profile 23, and the plug-in surface 331 has a supporting portion 3311.

[0178] In this embodiment, the third profile 23 is made of materials including, but not limited to, aluminum alloy and magnesium alloy. In addition to being connected to the cover plate 11, the third profile 23 also connects to the second waterproof structure 42. The second waterproof structure 42 shields the surface of the third profile 23, preventing water, dust, and other impurities from entering other components or the interior of the trunk 201 through the third profile 23. Therefore, a good sealing connection between the third profile 23 and the cover plate 11 is required. If the cover plate 11 and the third profile 23 become loose or separate, water, dust, and other impurities can enter other components or the interior of the trunk 201 through the third profile 23.

[0179] This embodiment defines a second engaging groove 231 on one side of the third profile 23, and a corresponding mounting portion is provided on the second waterproof structure 42. This mounting portion is positioned within the second engaging groove 231, thereby achieving connection between the second waterproof structure 42 and the third profile 23. The second engaging groove 231 is formed by bending one side of the third profile 23 toward the interior of the third profile 23, rather than simply defining a second engaging groove 231 on one side of the third profile 23. Furthermore, the second engaging groove 231 extends along the extension direction of the third profile 23, ensuring that the second waterproof structure 42 completely covers and shields the third profile 23 along its length during subsequent assembly.

[0180] Furthermore, because the second snap-fitting groove 231 is formed by bending one side of the third profile 23, it has an opening, and the arcuate second snap-fitting groove 231 also has a diameter. This embodiment allows the opening width of the second snap-fitting groove 231 to be smaller than its diameter. Consequently, regardless of the method used to insert the arcuate second snap-fitting groove 231 of the second waterproof structure 42 into the second snap-fitting groove 231, the smaller opening makes it difficult for the second snap-fitting rib 422 to be removed from the second snap-fitting groove 231. This increases the difficulty of removing the second snap-fitting rib 422 from the second snap-fitting groove 231, preventing the second snap-fitting rib 422 from separating from the second snap-fitting groove 231 along the vertical direction, i.e., the arrangement direction of the third profile 23 and the second waterproof structure 42. This improves the tightness of the connection between the third profile 23 and the second waterproof structure 42, and prevents the third profile 23 from separating from the second waterproof structure 42.

[0181] Optionally, one side of the third profile 23 includes a first portion 232 and a second portion 233. The first portion 232 is disposed between the two second engaging grooves 231, and the second portion 233 is disposed on the side of the second engaging groove 231 facing away from the first portion 232, with the first portion 232 protruding from the second portion 233. The third profile 23 may include one first portion 232 and two second portions 233. The first portion 232 may be disposed between the two second engaging grooves 231, one second portion 233 may be disposed on the side of one second engaging groove 231 facing away from the first portion 232, and the other second portion 233 may be disposed on the side of the other second engaging groove 231 facing away from the first portion 232. In other words, one side of the third profile 23 may include, in order, the second portion 233, the second engaging groove 231, the first portion 232, the second engaging groove 231, and the second portion 233. In this embodiment, the first portion 232 can protrude from the second portion 231 , thereby eliminating the dents of the second waterproof structure 42 , increasing extrusion positioning, and improving the appearance and positioning effects of the second waterproof structure 42 .

[0182] In this embodiment, the third connector 33 utilizes the insertion surface 331 to achieve axial connection and sealing of the third profile 23. In this embodiment, abutment 3311 may also be provided on the insertion surface 331. The position of the abutment 3311 is controlled so that the third connector 33, in addition to being inserted into the axial end surface of the third profile 23, can also abut the top surface of the second waterproof structure 42 provided on the third profile 23 using the abutment 3311.

[0183] Optionally, the top surface 3312 of the third connector 33 is disposed on the same side as the top surface 3312 of the third profile 23. The top surface 3312 of the third connector 33 is provided with two spaced-apart receiving grooves 323 and a second partition 3314 disposed between the two receiving grooves 323. The second partition 3314 and the abutting portion 3311 are integrally formed. The receiving grooves 323 are used to accommodate the second waterproof structure 42. The bottom wall of each receiving groove 323 is provided with an arcuate second engaging groove 231. Each second engaging groove 231 is configured to engage with a second engaging rib 422 of a second waterproof structure 42. The two second waterproof structures 42 are disposed on opposite sides of the second partition 3314. In this embodiment, an arcuate second engaging groove 231 may also be provided on the bottom wall of each receiving groove 323. The arcuate second engaging groove 231 engages with the second engaging rib 422 of the second waterproof structure 42, thereby enhancing the connection between the second waterproof structure 42 and the third connector 33.

In this embodiment, the waterproof component 4 includes: a first waterproof structure 41, including a first waterproof part 41a, the first waterproof part 41a includes a first bearing portion 411, a first snap-fitting rib 412, a first water retaining portion 413 and a first sealing portion 414, the first snap-fitting rib 412 is protruded on one side of the first bearing portion 411 and is used to snap into the first snap-fitting groove 218 of the first profile 21 near the driving cabin 202 of the mobile device 20, and the first snap-fitting groove 218 of the first profile 21 near the tail of the trunk 201, the first water retaining portion 413 is protruded on the other side opposite to the first bearing portion 411, and the first sealing portion 414 is protruded on the other side opposite to the first bearing portion 411. One end 4141 is arranged on the other side opposite to the first bearing portion 411, and the first sealing portion 414 is bent in a direction away from the first bearing portion 411 so that the second end 4142 opposite to the first sealing portion 414 is arranged on the side of the first water retaining portion 413 away from the first end 4141. The first sealing portion 414 and the first bearing portion 411 are surrounded to form a sealed space, the first water retaining portion 413 is arranged in the sealed space, and the second end 4142 protrudes from the first bearing portion 411 in the direction in which the first end 4141 points to the first water retaining portion 413, and the second end 4142 of the first sealing portion 414 can rotate relative to the first bearing portion 411.

[0187] In this embodiment, the first waterproof structure 41 includes a first waterproof member 41a, which is used to be installed on the first profile 21 of the edge of the foldable cover 10 close to the tail of the trunk 201 of the mobile device 20, and / or, is used to be installed on the first profile 21 of the edge of the foldable cover 10 close to the side of the trunk 201 of the mobile device 20 close to the driving cabin 202, so as to seal the edges of the foldable cover 10 on opposite sides in the length direction.

[0188] In this embodiment, the first waterproof member 41a includes a first bearing portion 411, a first snap-fitting rib 412, a first water retaining portion 413, and a first sealing portion 414. The first snap-fitting rib 412 is used to snap the first bearing portion 411 into the first snap-fitting groove 218 of the first profile 21. The first end 4141 of the first sealing portion 414 is connected to the first bearing portion 411, and the first sealing portion 414 is bent in a direction away from the first bearing portion 411 so that the second end 4142 is located on a side of the first water retaining portion 413 away from the first end 4141. The first sealing portion 414 and the first bearing portion 411 enclose a sealed space. The second end 4142 can rotate relative to the first bearing portion 411 to open or close the sealed space. Because the second end 4142 protrudes from the first bearing portion 411 in the direction from the first end 4141 to the first water retaining portion 413, so that when the second end 4142 is protruding from the edge of the first profile 21 in the direction from the first end 4141 to the first water retaining portion 413, when the first sealing portion 414 abuts against the first bearing portion 411 near the second end 4142, the second end 4142 closes to seal the sealed space, thereby better preventing external water from flowing into the trunk 201 of the mobile device 20 through the edge of the first profile 21. Even if some water seeps into the space between the first profile 21 and the first sealing portion 414, the seeped water will flow into the sealed space and be blocked by the first water retaining portion 413, preventing the water from flowing into the trunk 201 of the mobile device 20, thereby achieving a multi-stage waterproof effect. Furthermore, since the second end 4142 can rotate relative to the first bearing portion 411, when water in the sealed space needs to be drained, the sealed space can be opened from the second end 4142 to actively drain the water, thereby facilitating drying and cleaning.

[0189] Optionally, one side of the first bearing portion 411 is configured to abut the first sidewall 219a of the first profile 21, and the second end 4142 of the first sealing portion 414 is configured to shield the first sidewall 219a. In the direction from the first end 4141 toward the first water retaining portion 413, the second end 4142 protrudes from the first sidewall 219a. Alternatively, the second end 4142 of the first sealing portion 414 partially shields the cover plate 11 disposed on the first profile 21.

[0190] Optionally, the first snap-fitting rib 412 includes a first main body 4121 and a snap-fitting block 4122. One end of the first main body 4121 is connected to the first supporting portion 411, and the snap-fitting block 4122 is connected to the other end of the first main body 4121. In a direction perpendicular to the extension direction of the first snap-fitting rib 412, the width of the snap-fitting block 4122 on the side closer to the first main body 4121 is greater than the width of the snap-fitting block 4122 on the side farther from the first main body 4121. This allows the snap-fitting block to better snap into the first snap-fitting groove 218 of the first profile 21, thereby improving the stability of the connection between the first supporting portion 411 and the first profile 21 and enhancing the waterproofing effect.

[0191] Optionally, the first waterproof structure 41 includes two first waterproof members 41a, which are disposed opposite each other. One sealing member is snapped into the first snap-fit ​​groove 218 of the first profile 21 near the tailgate 2011 of the trunk 201, and its second end 4142 abuts against the first sidewall 219a of the first profile 21 when pressed by the tailgate 2011 of the trunk 201. The other sealing member is snapped into the first snap-fit ​​groove 218 of the first profile 21 near the driver's compartment 202 of the mobile device 20, and its first end 4141 abuts against the inner wall of the trunk 201 near the driver's compartment 202.

[0192] The two first waterproof members 41a being disposed facing each other means that the second ends 4142 of the two first waterproof members 41a are oriented in the same direction. Specifically, one first waterproof member 41a is mounted on the first profile 21 of the cover plate 11 near the tailgate 2011 of the mobile device 20. The side of the first bearing portion 411 near the second end 4142 abuts the first sidewall 219a of the first profile 21, and the second end 4142 protrudes from the first sidewall 219a. The portion of the first sealing portion 414 near the second end 4142 is squeezed by the tailgate 2011 of the mobile device 20, causing the second end 4142 to close, sealing the structure and achieving a waterproof effect. Another first waterproof component 41a is installed on the first profile 21 of the cover 11 near the driving cabin 202 of the mobile device 20, and the side of the first bearing portion 411 near the first end 4141 abuts against the first side wall 219a of the first profile 21, and the second end 4142 protrudes from the other end of the first profile 21 opposite to the first side wall 219a and is placed on the cover 11 to cover part of the cover 11. The part of the first sealing portion 414 near the first end 4141 abuts against the inner wall of the trunk 201 of the mobile device 20 near the driving cabin 202 to squeeze the part of the first sealing portion 414 near the first end 4141, and the extrusion force is transmitted from the part of the first sealing portion 414 near the first end 4141 to the second end 4142, so that the sealed space is closed, thereby achieving a waterproof effect.

[0193] In this embodiment, the first waterproof structure 41 also includes a second waterproof member 41b, which includes a second load-bearing portion 415 and two ridges 416 spaced apart on one side of the second load-bearing portion 415. The side of the second load-bearing portion 415 facing away from the ridges 416 is used to connect to the first profile 21, and the two ridges 416 are used to press fit to the trunk 201. The extension direction of the second waterproof member 41b intersects with the extension direction of the first waterproof member 41a. The ridges 416 are elastic and have inclined surfaces 4161 facing the other ridge 416. The two inclined surfaces 4161 are inclined in opposite directions, so that the ridges 416 bend and deform in a direction away from the other ridge 416 under the action of external forces.

[0194] In this embodiment, the surface of the second bearing portion 415 facing away from the protrusion 416 is used to be fixed to the first profile 21 by bonding, and the first profile 21 connected to the second waterproof member 41b and the first profile 21 connected to the first waterproof member 41a are located on adjacent sides of the cover 11, so that the extension direction of the second waterproof member 41b intersects with the extension direction of the second waterproof member 41b. Specifically, the second waterproof member 41b is used to be installed on the first profile 21 on the side of the foldable cover 10.

[0195] The ridge 416 is elastic, and the ridge 416 has an inclined surface 4161 facing the other ridge 416, and the two inclined surfaces 4161 are inclined in opposite directions, so that when the foldable cover 10 is installed on the trunk 201, the ridge 416 is pressed to the trunk 201 under the action of the gravity of the foldable cover 10 and the first profile 21, so that the ridge 416 is bent and deformed in the direction away from the other ridge 416, thereby sealing the space between the two ridges 416, thereby improving the fit between the second waterproof component 41b and the trunk 201, thereby improving the waterproof effect.

[0196] Optionally, the first waterproof structure 41 includes a first buffer block 417 connecting the first waterproof member 41 a and the second waterproof member 41 b , and a second buffer block 418 provided at an end of the second waterproof member 41 b away from the first buffer block 417 .

[0197] Please refer to Figures 29, 36, 50-54, Figure 50 is a schematic structural diagram of the second waterproof structure in Figure 2; Figure 51 is a schematic structural diagram of the end face of the second waterproof structure in Figure 50; Figure 52 is a schematic structural diagram of the second waterproof structure in Figure 50 being clamped to the second clamping groove; Figure 53 is a partial enlarged schematic diagram of point V in Figure 51; Figure 54 is a partial enlarged schematic diagram of point VI in Figure 51. In this embodiment, a second clamping groove 231 is provided on the top surface of the second profile 22; the waterproof assembly 4 includes: a plurality of second waterproof structures 42, the waterproof structure 42 includes a sealing plate 421 and two second clamping ribs 422 provided on one side of the sealing plate 421, one second clamping rib 422 in some of the second waterproof structures 42 is clamped into one second clamping groove 231, and the other second clamping rib 422 is clamped into another second clamping groove 231 set at an interval, so as to shield the two second profiles 22 connected in rotation. The gap between them, or the gap between the second profile 22 and the third profile 23 that are connected to each other for blocking rotation, wherein, along the extension direction of the second clamping rib 422, the second clamping rib 422 has a first fixing hole 4221; the supporting portion 3311 is supported to the top surface of the sealing plate 421, and the second connecting member 32 and the third connecting member 33 are both provided with a locking hole 326 connected to the first fixing hole 4221, and the locking hole 326 and the first fixing hole 4221 are used to insert the fixing member 423 to fix the second waterproof structure 42.

[0198] In this embodiment, the second waterproof structure 42 is respectively connected to the two second snap-fit ​​grooves 231 arranged at intervals between each other through two snap-fit ​​ribs 422, so that the sealing plate 421 can block the gap between the two spaced cover plates 11. Specifically, the two snap-fit ​​ribs 422 of the second waterproof structure 42 are spaced apart on the same surface of the sealing plate 421, wherein one snap-fit ​​rib 422 is connected to one second snap-fit ​​groove 231, and the other snap-fit ​​rib 422 is connected to another second snap-fit ​​groove 231 arranged at an adjacent interval, so that the sealing plate 421 can block the gap between the two spaced cover plates 11, thereby achieving a waterproof effect. In addition, during the relative rotation of the two adjacent cover plates 11, the sealing plate 421 can bend and deform to follow the rotation of the two adjacent cover plates 11, and the two snap-fit ​​ribs 422 always remain connected to the second snap-fit ​​grooves 231, so that the sealing plate 421 can always block the gap between the two adjacent cover plates 11, thereby improving the waterproof effect of the second waterproof structure 42.

[0199] Furthermore, the snap-fitting rib 422 has a first fixing hole 4221, which is used to insert a fixing part 423 to improve the connection stability between the snap-fitting rib 422 and the second snap-fitting groove 231, thereby improving the connection stability between the second waterproof structure 42 and the two adjacent second profiles 22 or the adjacent second profiles 22 and the third profile 23, thereby further improving the waterproof effect of the second waterproof structure 42.

[0200] Furthermore, the clamping rib 422 can be pressed into the second clamping groove 231 in a direction perpendicular to the extension of the clamping rib 422, and the fixing member 423 can be inserted into the first fixing hole 4221 in the direction of the extension of the clamping rib 422 to secure the second waterproof structure 42. In other words, the clamping rib 422 can be clamped into the second clamping groove 231 by pressing the sealing plate 421. After the clamping rib 422 is clamped into the second clamping groove 231, the surface of the sealing plate 421 facing the second profile 22 or the third profile 23 can be attached to the second profile 22 or the third profile 23. Furthermore, the second profile 22 and the third profile 23 are provided with a locking hole 326 that communicates with the first fixing hole 4221. The fixing member 423 can be inserted into the first fixing hole 4221 through the locking hole 326 to further secure the second waterproof structure 42 to the second profile 22 or the third profile 23, thereby improving waterproof stability.

[0201] Optionally, a convex rib 424 is provided on the inner wall of the first fixing hole 4221 . At least one of the convex rib 424 and the clamping rib 422 is elastic. The convex rib 424 is used to clamp the fixing piece 423 .

[0202] Optionally, the clamping rib 422 is elastic and has a groove 4222 formed therein. The opening of the groove 4222 is configured to expand after the fixing member 423 is inserted into the first fixing hole 4221. In this embodiment, after the fixing member 423 is inserted into the first fixing hole 4221, the clamping rib 422 expands and deforms under the pressure of the fixing member 423. The provision of the groove 4222 reduces the deformation resistance of the clamping rib 422, thereby reducing the resistance to the insertion of the fixing member 423 into the first fixing hole 4221.

[0203] Optionally, at least a portion of the fitting portion 425 gradually becomes smaller in a direction away from the sealing plate 421, so that after the snap-in rib 422 is snapped into the second snap-in groove 231, the fitting portion 425 is deformed toward the second profile 22 or the third profile 23, thereby making the fitting portion 425 fit more closely with the second profile 22 or the third profile 23, thereby improving the waterproof effect of the second waterproof structure 42 at the second profile 22 or the third profile 23.

[0204] Furthermore, the thickness of the fitting portion 425 is less than the thickness of the sealing plate 421. The fitting portion 425 has an upper surface 4251, a lower surface 4252 disposed opposite to the upper surface 4251, and a first side surface 4253 connecting the upper surface 4251 and the lower surface 4252. The upper surface 4251 and the lower surface 4252 are inclined toward the clamping rib 422 relative to the sealing plate 421. The first side surface 4253 is inclined toward the sealing plate 421 relative to the lower surface 4252. The thickness of the fitting portion 425 is less than that of the sealing plate 421. This facilitates deformation of the fitting portion 425 away from the second profile 22 or the third profile 23 after the clamping rib 422 is clamped to the second clamping groove 231, thereby improving the fit between the fitting portion 425 and the second profile 22 or the third profile 23. The upper surface 4251 and the lower surface 4252 are inclined toward the clamping rib 422 compared to the sealing plate 421, and the first side surface 4253 is inclined toward the sealing plate 421 compared to the lower surface 4252, further improving the deformation size of the fitting portion 425 fitting to the second profile 22 or the third profile 23 after the clamping rib 422 is clamped to the second clamping groove 231, thereby further improving the fit between the fitting portion 425 and the second profile 22 or the third profile 23 to achieve better waterproof effect.

[0205] Please refer to Figure 5, Figure 55-Figure 62, Figure 55 is a schematic diagram of the foldable cover in Figure 5 from another perspective; Figure 56 is a partial enlarged schematic diagram of point VII in Figure 5; Figure 57 is a partial enlarged schematic diagram of point VIII in Figure 55; Figure 58 is a structural schematic diagram of the rotating structure in Figure 2; Figure 59 is a structural schematic diagram of the rotating structure in Figure 5; Figure 60 is a structural schematic diagram of the rotating structure in Figure 58 after being cut along line BB; Figure 61 is a structural schematic diagram of the rotating seat in Figure 58; Figure 62 is a structural schematic diagram of the rotating structure in Figure 58 from another perspective. In this embodiment, the foldable cover 10 also includes a rotating mechanism 6, which includes two rotating components 60 connected in rotation. The rotating component 60 includes: at least two rotating arms 61, the rotating arm 61 having a third end 611 and a fourth end 612 arranged opposite to each other; a rotating seat 62, having a first surface 621 and a second surface 622 arranged opposite to each other, and a third surface 623 connecting the first surface 621 and the second surface 622. The first surface 621 of one rotating component 60 is arranged toward the other rotating component 60. The rotating seat 62 is provided with at least two second limiting holes 624 that pass through the first surface 621, the second surface 622 and the third surface 623. Each second limiting hole 624 is used to accommodate the third end 611 of a rotating arm 61, and the second surface 622 is provided with a second limiting hole 624. A connected sliding groove 625; a first rotating shaft 63, passing through the third end 611 and slidingly installed in the sliding groove 625; and a second rotating shaft 64, the second rotating shaft 64 in one rotating component 60 is rotatably connected to the rotating seat 62 and passes through the fourth end 612 in another rotating component 60, so as to rotatably connect the rotating arm 61 in the other rotating component 60 to the rotating seat 62 in one rotating component 60; wherein, the rotating mechanism 6 arranged between the cover plate 11 near the rear of the trunk 201 and the cover plate 11 located in the middle is respectively connected to the two second profiles 22 through two rotating seats 62; the rotating mechanism 6 arranged between the cover plate 11 near the cab 202 and the cover plate 11 located in the middle is respectively connected to the second profile 22 and the third profile 23 through two rotating seats 62.

[0206] In this embodiment, the first rotating shaft 63 passes through the third end 611 and is slidably installed in the sliding groove 625, so that one rotating component 60 can drive the first rotating shaft 63 to move relative to the rotating seat 62 in the sliding groove 625 through the rotating arm 61 to rotate relative to another rotating component 60. Since the first rotating shaft 63 can move in the sliding groove 625, the rotational freedom of one rotating component 60 relative to another rotating component 60 is improved when the length of the rotating arm 61 is constant, which is beneficial to improving the structural compactness of the rotating mechanism 6, thereby improving the structural strength of the rotating mechanism 6 and reducing the size of the rotating mechanism 6.

[0207] Furthermore, the second rotation shaft 64 of one rotational assembly 60 is rotationally connected to the rotation base 62 and passes through the fourth end 612 of the other rotational assembly 60, thereby rotationally connecting the rotation arm 61 of the other rotational assembly 60 to the rotation base 62 of the one rotational assembly 60. That is, the rotation arms 61 of the two rotational assemblies 60 are mutually overlapped to the other rotation base 62 and rotationally connected to the other rotation base 62 via the other rotation shaft 64. During the rotation of one rotational assembly 60 relative to the other rotational assembly 60, the one rotational assembly 60 can rotate relative to the other rotational assembly 60 using the third end 611 and the fourth end 612 of the other rotational assembly 60 as rotation fulcrums, thereby improving the stability of the two rotational assemblies 60 during relative rotation.

[0208] In this embodiment, when two adjacent cover plates 11 are rotatably connected via the second profile 22, one rotating assembly 60 in the rotating mechanism 6 is mounted on one second profile 22, and the other rotating assembly 60 is mounted on the other adjacent second profile 22, so that the two adjacent cover plates 11 can be rotated by the rotating mechanism 6, thereby achieving one cover plate 11 rotating and folding onto the other cover plate 11 to reveal an opening. When a third profile 23 is provided between two adjacent second profiles 22, each second profile 22 and third profile 23 are connected via the rotating mechanism 6, so that one cover plate 11 can rotate relative to the third profile 23 and drive the third profile 23 to rotate relative to the other cover plate 11, so that one cover plate 11 can drive the third profile 23 to overlap the other cover plate 11. Since the third profile 23 can provide a gap between the two adjacent cover plates 11 after being stacked to accommodate the third cover plate 11, the foldable cover plate 10 can achieve secondary folding.

[0209] Please refer to Figures 1 and 63-69. Figure 63 is a perspective exploded view of the cover assembly in Figure 2; Figure 64 is a cross-sectional view of the cover assembly in Figure 2; Figure 65 is a structural schematic diagram of the support layer in Figure 63; Figure 66 is a partial top view of Figure 65; Figure 67 is a cross-sectional view of another embodiment of the cover assembly in Figure 2; Figure 68 is a cross-sectional view of another embodiment of the cover assembly in Figure 2; and Figure 69 is a structural schematic diagram of another embodiment of the foldable cover in Figure 2 from another perspective. In this embodiment, the cover assembly 1 further includes: a photovoltaic panel 12 having a light-absorbing surface 121 and a backlight surface 122 disposed opposite to each other; and an adhesive layer 13 bonded to the backlight surface 122; the cover 11 is bonded to the side of the adhesive layer 13 facing away from the photovoltaic panel 12. The cover 11 includes a support layer 111 and a reinforcement layer 112. The reinforcement layer 112 is disposed on at least one side of the support layer 111. The support layer 111 includes a plastic support layer 111 or an aluminum support layer 111.

[0210] The cover assembly 1 primarily includes a photovoltaic panel 12, an adhesive layer 13, and a cover 11. The adhesive layer 13 is bonded between the photovoltaic panel 12 and the cover 11. Optionally, the adhesive layer 13 includes, but is not limited to, polyethylene terephthalate (PET) glue, epoxy resin glue, ketoprofen (KPF) liposome gel, and the like. Furthermore, KPF glue can be used to further improve the surface flatness of the adhesive layer 13, thereby better bonding to the cover 11 and enhancing bonding performance.

[0211] The cover plate 11 is mainly used to support the photovoltaic panel 12, and plays a role in supporting and fixing the photovoltaic panel 12. The photovoltaic panel 12 can also be called a solar panel, which is mainly used to absorb natural light, non-natural light and other light and convert light energy into electrical energy to power other electrical equipment. Therefore, the photovoltaic panel 12 has a light-absorbing surface 121 that absorbs light, and a backlight surface 122 opposite to the light-absorbing surface 121. The above content can also be understood as one side of the adhesive layer 13 is on the backlight surface 122, and the other side is bonded to the cover plate 11. Compared with the traditional cover plate 11, the present embodiment integrates the photovoltaic panel 12 on the cover plate 11. While achieving the purpose of covering the opening of the trunk 201, the photovoltaic panel 12 in the cover plate assembly 1 can also be used to convert light energy into electrical energy, thereby providing electrical energy for electrical equipment.

[0212] The cover plate 11 mainly includes a support layer 111 and a reinforcement layer 112, wherein the support layer 111 is mainly used to support the photovoltaic panel 12. The material of the support layer 111 is mainly plastic or aluminum, and the aluminum material can be aluminum or aluminum alloy. Optionally, the material of the plastic includes but is not limited to polyethylene (PP). The use of a plastic support layer 111 or an aluminum support layer 111 in this application can reduce the weight of the cover plate 11 under the same size and volume, achieve lightweight products, reduce production and manufacturing, installation and transportation costs, and have good heat insulation effect without absorbing heat. In addition, the support layer 111 made of polypropylene has corrosion resistance and a long service life, and can be recycled and reused without causing pollution to the environment.

[0213] In addition, the reinforcing layer 112 plays a reinforcing role. The reinforcing layer 112 cooperates with the supporting layer to improve the structural strength of the cover plate 11 , thereby well supporting the cover plate 11 .

[0214] Alternatively, the material of the reinforcement layer 112 includes, but is not limited to, fiberglass reinforced plastic (FRP). FRP is a plastic reinforced with glass fiber in an unsaturated polyester, epoxy resin, and phenolic resin matrix. Reinforced plastics using glass fiber or its products as reinforcement are called fiberglass reinforced plastics, or FRP. The FRP reinforcement layer 112, when combined with the photovoltaic panel 12, offers strong impact and compression resistance, as well as excellent thermal insulation properties.

[0215] The support layer 111 is not a solid layer, but rather a structure composed of multiple interconnected and spliced ​​annular support portions 1111. Each annular support portion 1111 has a third through hole 1112 extending from the light-absorbing surface 121 to the backlight surface 122. In this case, the support layer 111 can also be referred to as a PP honeycomb core. This shows that the use of annular support portions 1111, in addition to supporting the photovoltaic panel 12, can further reduce the weight of the support layer 111 and the cover plate 11.
