DETAILED DESCRIPTION

[0074] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0075] The embodiments of the present application provide a trunk assist device and a vehicle, which are used in the trunk of the vehicle.

[0076] Figure 1 This is a schematic diagram of the structure of an embodiment of the trunk assist device provided in the present application, wherein the sliding assembly and the lifting assembly drive the storage plate to rise and move above the boss. Figure 1 As shown, the trunk assist device 10 includes a guide rail 11, a sliding assembly 12 and a lifting assembly 13. The sliding assembly 12 is slidably installed on the guide rail 11, and the lifting assembly 13 is installed on the sliding assembly 12. The lifting assembly 13 is used to connect with the storage plate 16 to drive the storage plate 16 to rise and fall.

[0077] The trunk assist device 10 of the embodiment of the present application is provided by slidingly installing the sliding assembly 12 on the guide rail 11, and installing the lifting assembly 13 for connecting with the storage plate 16 and driving the storage plate 16 to rise and fall on the sliding assembly 12. When it is necessary to take out the items on the storage plate 16, the storage plate 16 can be driven to rise by the lifting assembly 13, and the storage plate 16 can be driven to move toward the outside of the trunk by moving the sliding assembly 12 along the guide rail 11, so that the use of the storage plate 16 can be more convenient. When it is not necessary to take out the items on the storage plate, the storage plate 16 can be driven to move along the guide rail 11 to the inside of the trunk and lower the height by the lifting assembly 13, so as to reduce the height space occupied by the storage plate 16 in the trunk.

[0078] The trunk assist device 10 may further include a power assembly 14, which may enable the lifting assembly 13 to include at least one lifting mechanism 131, the at least one lifting mechanism 131 being installed on the sliding assembly 12, and the at least one lifting mechanism 131 being used to connect with the storage board 16. Thus, by sliding the lifting assembly 13 relative to the sliding assembly 12, the storage board 16 may be driven to slide in the vehicle. The power assembly 14 is transmission-connected to the at least one lifting mechanism 131, and is used to drive the at least one lifting mechanism 131 to drive the storage board 16 to rise and fall. Thus, when the trunk assist device 10 is installed in the trunk of the vehicle, the trunk assist device 10 may automatically raise and lower the storage board 16 through the power assembly 14, without the need to manually lift the storage board 16, making the lifting and lowering of the storage board 16 easier.

[0079] It should be noted that the number of the lifting mechanisms 131 can be one or more, which can be determined according to the structure of the lifting mechanisms 131 and the storage plate 16. It is sufficient that the lifting assembly 13 can stably drive the storage plate 16 to rise and fall.

[0080] In some embodiments, Figures 1 to 5As shown, the lifting mechanism 131 may include a lifting frame 1311 and a connecting member 1315, the lifting frame 1311 is installed on the sliding assembly 12, the connecting member 1315 is connected to the lifting frame 1311, and the connecting member 1315 is also used to connect to the storage board 16, and the power assembly 14 is connected to the lifting frame 1311 in a transmission connection to drive the lifting frame 1311 to drive the connecting member 1315 to move up and down. When the power assembly 14 drives the lifting frame 1311 to drive the connecting member 1315 to move up and down, the storage board 16 connected to the connecting member 1315 can be moved up and down. Moreover, the lifting frame 1311 is connected to the storage board 16 through the connecting member 1315, which can make the connection between the lifting frame 1311 and the storage board 16 more convenient.

[0081] The lifting frame 1311 may include a sliding member 1312, a first connecting rod 1313 and a second connecting rod 1314. The sliding member 1312 is slidably mounted on the sliding assembly 12. The first connecting rod 1313 and the second connecting rod 1314 are hinged to each other. One end of the first connecting rod 1313 is hinged to the sliding member 1312, one end of the second connecting rod 1314 is hinged to the sliding assembly 12, and the other end of the first connecting rod 1313 and / or the second connecting rod 1314 is hinged to the connecting member 1315. The power assembly 14 is in transmission connection with the sliding member 1312 and is used to drive the sliding member 1312 to slide relative to the sliding assembly 12, so as to drive the first connecting rod 1313 and the second connecting rod 1314 to rotate relative to each other, so as to lift and lower the connecting member 1315.

[0082] Thus, the first link 1313 and the second link 1314 can be connected to form a structurally stable scissor-type lifting frame 1311 structure. When the power component 14 drives the sliding member 1312 to slide relative to the sliding component 12, the first link 1313 and the second link 1314 can rotate relative to each other, so that the other end of the first link 1313 and / or the second link 1314 hinged to the connecting member 1315 rises or falls, thereby driving the connecting member 1315 to rise and fall.

[0083] In some embodiments, the other end of the first connecting rod 1313 can be hinged to the connecting member 1315, and the other end of the second connecting rod 1314 can be hinged between the two ends of the first connecting rod 1313. In this way, the length of the second connecting rod 1314 can be shortened, which is conducive to reducing the cost and weight of the lifting frame 1311. In addition, the risk of interference between the second connecting rod 1314 and other components during the lifting process of the lifting frame 1311 can also be reduced.

[0084] It should be noted that the other end of the second connecting rod 1314 can be hinged to the middle of the first connecting rod 1313, or can be hinged to other positions of the first connecting rod 1313, as long as the part of the first connecting rod 1313 used to hinge with the second connecting rod 1314 is located between the two ends of the first connecting rod 1313.

[0085] Specifically, the sliding direction of the sliding member 1312 relative to the sliding assembly 12 is substantially parallel to the length direction of the vehicle. The length direction of the first connecting rod 1313 and the second connecting rod 1314 is substantially perpendicular to the width direction of the vehicle. The first connecting rod 1313 extends along the width direction of the vehicle relative to the rotation axis of the sliding assembly 12 and the connecting member 1315. The second connecting rod 1314 extends along the width direction of the vehicle relative to the rotation axis of the first connecting rod 1313, the sliding assembly 12 and the connecting member 1315.

[0086] In other embodiments, the other end of the second connecting rod 1314 may be hinged to the connecting member 1315, and the other end of the first connecting rod 1313 may be hinged between the two ends of the second connecting rod 1314. In this way, the length of the first connecting rod 1313 can be shortened, which is beneficial to reducing the cost and weight of the lifting frame 1311. In addition, the risk of interference between the first connecting rod 1313 and other components during the lifting process of the lifting frame 1311 can be reduced.

[0087] It should be noted that the other end of the first connecting rod 1313 can be hinged to the middle of the second connecting rod 1314, or can be hinged to other positions of the second connecting rod 1314, as long as the part of the second connecting rod 1314 used to be hinged to the first connecting rod 1313 is located between the two ends of the second connecting rod 1314.

[0088] In addition, the other ends of the first connecting rod 1313 and the second connecting rod 1314 can be respectively hinged to the two ends of the connecting member 1315 along the length direction of the guide rail 11, and the other ends of the first connecting rod 1313 and / or the second connecting rod 1314 are slidably connected to the connecting member 1315 along the length direction of the guide rail 11. Therefore, when the power assembly 14 drives the sliding member 1312 to slide relative to the sliding assembly 12, the first connecting rod 1313 and the second connecting rod 1314 can be relatively rotated, so that the other ends of the first connecting rod 1313 and the second connecting rod 1314 hinged to the connecting member 1315 rise or fall at the same time, thereby driving the connecting member 1315 to rise and fall. Since the first connecting rod 1313 and the second connecting rod 1314 both support the connecting member 1315, the lifting process of the connecting member 1315 can be made more stable.

[0089] In some embodiments, Figure 5As shown, the lifting mechanism 131 may further include a limiting structure 133, which is used to limit the sliding distance of the sliding member 1312 relative to the sliding assembly 12, so as to limit the height of the lifting frame 1311 driving the connecting member 1315 to rise and fall. It can be understood that by limiting the sliding distance of the sliding member 1312 relative to the sliding assembly 12 by the limiting structure 133, the angle range of relative rotation of the first connecting rod 1313 and the second connecting rod 1314 can be limited, thereby limiting the lifting height of the other end of the first connecting rod 1313 and / or the second connecting rod 1314 connected to the connecting member 1315, thereby limiting the height of the lifting frame 1311 driving the connecting member 1315 to rise and fall.

[0090] like Figure 5 As shown, the sliding assembly 12 includes a hinged portion 1211, and the hinged portion 1211 is hinged to one end of the second connecting rod 1314, so that one end of the second connecting rod 1314 is hinged to the sliding assembly 12. The limiting structure 133 can include a first limiting member 1331, which is arranged between the sliding member 1312 and the hinged portion 1211, and the first limiting member 1331 is used to abut against the sliding member 1312.

[0091] It can be understood that when the power assembly 14 drives the sliding member 1312 to slide in the direction close to the hinge part 1211, the sliding member 1312 can drive the first connecting rod 1313 to rotate relative to the second connecting rod 1314, so that the angle formed by the first connecting rod 1313 and the second connecting rod 1314 is reduced, and the height of the other end of the first connecting rod 1313 and the second connecting rod 1314 is increased, thereby increasing the height of the connecting member 1315 connected to the first connecting rod 1313 and / or the second connecting rod 1314 to increase the height of the storage plate 16.

[0092] When the first limit member 1331 disposed between the sliding member 1312 and the hinged portion 1211 abuts against the sliding member 1312, it can prevent the sliding member 1312 from continuing to drive the first connecting rod 1313 to rotate relative to the second connecting rod 1314, thereby limiting the connecting member 1315 from continuing to rise, thereby limiting the height to which the lifting frame 1311 drives the connecting member 1315 to rise.

[0093] In addition, the limiting structure 133 may also include a second limiting member 1332, which is located on the side of the sliding assembly 12 away from the hinge part 1211, and the sliding member 1312 is located between the first limiting member 1331 and the second limiting member 1332. The second limiting member 1332 is used to abut against the sliding member 1312 to limit the sliding member 1312 from sliding between the first limiting member 1331 and the second limiting member 1332.

[0094] It can be understood that when the power assembly 14 drives the sliding member 1312 to slide in a direction away from the hinge portion 1211, the sliding member 1312 can drive the first connecting rod 1313 to rotate relative to the second connecting rod 1314, so that the angle formed by the first connecting rod 1313 and the second connecting rod 1314 increases, and the height of the other end of the first connecting rod 1313 and the second connecting rod 1314 decreases, thereby causing the height of the connecting member 1315 connected to the first connecting rod 1313 and / or the second connecting rod 1314 to decrease, thereby lowering the height of the storage plate 16.

[0095] When the second limit member 1332 located on the side of the sliding assembly 12 away from the hinge part 1211 abuts against the sliding member 1312, it can prevent the sliding member 1312 from continuing to drive the first connecting rod 1313 to rotate relative to the second connecting rod 1314, thereby limiting the connection member 1315 from continuing to descend, thereby limiting the height to which the lifting frame 1311 drives the connection member 1315 to descend.

[0096] In some embodiments, the lifting assembly 13 may include a plurality of lifting mechanisms 131, which are respectively mounted on the sliding assembly 12, and the power assembly 14 is connected to the plurality of lifting mechanisms 131 in a transmission manner and is used to drive the plurality of lifting mechanisms 131 to synchronously lift the storage plate 16. Thus, the lifting assembly 13 can more stably drive the storage plate 16 to lift.

[0097] The lifting assembly 13 may further include a synchronous member 132, which is connected to at least two lifting mechanisms 131 and is used to synchronously drive the storage plate 16 to rise and fall. Thus, the synchronous member 132 can synchronize the rise and fall of at least two lifting mechanisms 131, which is conducive to making the rise and fall of the storage plate 16 more stable.

[0098] In some embodiments, the synchronous member 132 can also be used to drive the sliding assembly 12 to slide along the guide rail 11 through the lifting mechanism 131. Thus, the power assembly 14 can not only drive the lifting mechanism 131 to lift the storage plate 16, but also can make the sliding assembly 12 slide along the slide rail 162 through the synchronous member 132 to drive the storage plate 16 to move.

[0099] The power assembly 14 can apply a driving force along the length direction of the guide rail 11 to the lifting mechanism 131 through the synchronous member 132, so as to drive the lifting mechanism 131 to lift the storage plate 16, and drive the sliding assembly 12 to slide along the guide rail 11 through the lifting mechanism 131. Therefore, the driving method of the power assembly 14 is relatively simple, which is conducive to simplifying the structure of the lifting assembly 13.

[0100] Specifically, the sliding assembly 12 includes at least two sliders 121 slidably mounted on the guide rail 11, and the at least two sliders 121 are sequentially distributed along the length direction of the guide rail 11, and each slider 121 is respectively provided with a corresponding lifting mechanism 131. Thus, the at least two lifting mechanisms 131 can support the storage plate 16, and the lifting of the storage plate 16 can be more stable.

[0101] The trunk assist device 10 includes at least two guide rails 11 which are arranged in parallel. Each guide rail 11 is respectively provided with a sliding component 12 and a lifting component 13 to further improve the stability of the trunk assist device 10 in driving the storage plate 16 to rise and fall and slide.

[0102] It should be noted that the number of guide rails 11 included in the trunk assist device 10 may be 2, 3, 4 or more. For example, the trunk assist device 10 may include 3 guide rails 11, and the 3 guide rails 11 are respectively provided with sliding components 12 and lifting components 13, wherein two lifting components 13 can drive the storage plate 16 to rise and fall under the drive of the power component 14, and the other lifting component 13 can be passively lifted and lowered during the lifting process of the storage plate 16. Thus, the storage plate 16 can be supported by the 3 lifting components 13, and more medium-sized storage plates 16 can be adapted, and the 3 lifting components 13 can form a three-point support structure for the storage plate 16, and the support for the storage plate 16 is more stable.

[0103] Of course, the trunk assist device 10 may also include four guide rails 11 or more guide rails 11 , which may be determined according to the size of the storage plate 16 .

[0104] In some embodiments, Figures 1 to 3 , Figure 6 As shown, the trunk assist device 10 may include a transmission structure 15, and the power assembly 14 transmits power to the synchronous member 132 through the transmission structure 15, so as to drive the lifting frame 1311 to drive the connecting member 1315 to rise and fall through the synchronous member 132. Therefore, the trunk assist device 10 can automatically drive the storage plate 16 to rise and fall and move through the power assembly 14, making the lifting and moving of the storage plate 16 easier and more labor-saving.

[0105] Among them, Figure 4 , Figure 6As shown, the transmission structure 15 may include a transmission belt 151, the transmission belt 151 includes a driving section 1511 and a return section 1513 arranged in parallel, one end of the driving section 1511 and the return section 1513 are respectively connected to the power assembly 14, the other ends of the driving section 1511 and the return section 1513 are connected to each other, and the driving section 1511 is connected to the synchronous member 132. The power assembly 14 is used to move the driving section 1511 and the return section 1513 in opposite directions to drive the synchronous member 132, so that the synchronous member 132 drives the lifting frame 1311 to drive the connecting member 1315 to rise and fall.

[0106] The driving section 1511 and the return section 1513 of the transmission belt 151 are moved in opposite directions through the power assembly 14, which can drive the synchronous member 132 to move back and forth, that is, the synchronous member 132 drives the lifting frame 1311 to drive the connecting member 1315 to rise or fall. The structure is relatively simple and the control is relatively convenient.

[0107] In some embodiments, the transmission structure 15 may further include a driving portion 1512 protruding from the outer periphery of the driving section 1511, and the synchronous member 132 may be provided with a connecting groove 1321, and the driving portion 1512 may be inserted into the connecting groove 1321, so that the driving section 1511 is connected to the synchronous member 132. Thus, the connection and separation of the synchronous member 132 and the connecting section may be more convenient, and the driving section 1511 may stably drive the synchronous member 132 to reciprocate.

[0108] Specifically, the synchronizer 132 extends along the length direction of the guide rail 11. Both ends of the synchronizer 132 are connected to the sliding members 1312 of the two lifting mechanisms 131. The connecting groove 1321 is opened between the two ends of the synchronizer 132. The synchronizer 132 is a plate-like structure. The connecting groove 1321 penetrates the synchronizer 132 along the thickness direction of the synchronizer 132.

[0109] In some embodiments, Figure 7 As shown, the driving section 1511 can be extended along the guide rail 11, and the driving section 1511 can be slidably installed on the guide rail 11 along the length direction of the guide rail 11. Therefore, during the movement of the driving section 1511, the synchronous member 132 can be stably driven to move along the length direction of the guide rail 11, so that the synchronous member 132 can stably drive the lifting mechanism 131 to drive the storage plate 16 to move up and down.

[0110] The guide rail 11 may include a mounting portion 110 extending along the length thereof, the mounting portion 110 is provided with a mounting groove 1101 extending along the length of the guide rail 11, the driving section 1511 is slidably mounted in the mounting groove 1101, and at least a portion of the driving portion 1512 extends out of the notch of the mounting groove 1101. Thus, the installation of the driving section 1511 can be made more stable, and the portion of the driving portion 1512 extending out of the notch of the mounting groove 1101 can be conveniently connected to the synchronizer 132.

[0111] In addition, a mounting hole 1102 extending along the length direction of the guide rail 11 may be provided, and the return section 1513 may be slidably mounted in the mounting hole 1102 along the length direction of the guide rail 11. Thus, the installation of the return section 1513 may be more stable.

[0112] In some embodiments, the power assembly 14 may include a driving motor 141 and a pulley 142, and the driving motor 141 is connected to the pulley 142 to drive the pulley 142 to rotate. One end of the driving section 1511 and the return section 1513 are connected to each other and sleeved on the pulley 142, so that the driving section 1511 and the return section 1513 are respectively connected to the power assembly 14. Therefore, the driving motor 141 can drive the driving section 1511 and the return section 1513 of the transmission belt 151 to move in opposite directions by driving the pulley 142 to rotate forward and reverse, and the structure and control method are relatively simple.

[0113] like Figure 5 and Figure 7 As shown, one of the guide rail 11 and the sliding assembly 12 is provided with a sliding portion 1212 , and the other of the guide rail 11 and the sliding assembly 12 is provided with a sliding groove 111 , and the sliding portion 1212 is slidably installed in the sliding groove 111 , so that the sliding assembly 12 is slidably installed on the guide rail 11 .

[0114] In some embodiments, a limiting portion 1213 may be provided on the side of the sliding portion 1212 and the sliding groove 111, and an anti-slip groove 1111 may be provided on the side of the sliding portion 1212 and the sliding groove 111. The limiting portion 1213 is slidably installed in the anti-slip groove 1111 to limit the sliding portion 1212 from slipping out of the sliding groove 111, thereby making the sliding connection between the sliding assembly 12 and the guide rail 11 more stable.

[0115] It should be noted that a limit portion 1213 may be provided on the side of the slide groove 111, and an anti-slip groove 1111 may be provided on the side of the sliding portion 1212. Alternatively, an anti-slip groove 1111 may be provided on the side of the slide groove 111, and a limit portion 1213 may be provided on the side of the sliding portion 1212.

[0116] Specifically, two opposite sides of the slide groove 111 are respectively provided with anti-slip grooves 1111. The anti-slip grooves 1111 extend along the length direction of the guide rail 11. The two sides of the slider 121 of the sliding assembly 12 are respectively provided with limiting parts 1213, and the two limiting parts 1213 of the slider 121 are slidably installed in the two anti-slip grooves 1111 of the slide groove 111 in a one-to-one correspondence. Among them, the total width of the limiting parts 1213 of the sliding assembly 12 is smaller than the width of the opening of the slide groove 111, so that after the limiting parts 1213 abut against the inner side of the anti-slip groove 1111 in the slide groove 111, the limiting parts 1213 can be limited in the slide groove 111 to prevent the limiting parts 1213 from slipping out of the opening of the slide groove 111.

[0117] In some embodiments, Figure 1 and Figure 2 As shown, the trunk assist device 10 further includes a bottom plate 17, one side of which is provided with a boss 171 and a receiving groove 172, the guide rail 11, the boss 171 and the receiving groove 172 are located on the same side of the bottom plate 17, and the boss 171 and the receiving groove 172 are distributed along the length direction of the guide rail 11. When the lifting assembly 13 drives the storage plate 16 to descend to the limit position, at least a portion of the storage plate 16 is received in the receiving groove 172. Thus, the height of the storage plate 16 can be reduced as much as possible, and the height difference between the storage plate 16 and the boss 171 can be reduced.

[0118] Among them, when the lifting assembly 13 drives the storage plate 16 to drop to the extreme position, the upper surface of the storage plate 16 can be flush with the upper surface of the boss 171, so as to further reduce the height difference between the storage plate 16 and the boss 171, so that the height space of the trunk occupied by the storage plate 16 is smaller, and the trunk assist device 10 is more beautiful.

[0119] In some embodiments, at least one crush groove may be provided on the side of the guide rail 11 away from the storage plate 16. Thus, when the vehicle is hit, if the guide rail 11 is subjected to a large impact force, the guide rail 11 will bend or even break at the crush groove to reduce the risk of the guide rail 11 intruding into the vehicle and causing casualties. Among them, the guide rail 11 may be provided with a plurality of crush grooves, and the plurality of crush grooves may be spaced apart along the length direction of the guide rail 11. Thus, when the guide rail 11 is subjected to a large impact force, the guide rail 11 may be bent into multiple sections at the plurality of crush grooves, which is conducive to further reducing the risk of the guide rail 11 intruding into the vehicle.

[0120] The trunk assist device 10 further includes a bottom plate 17. When the guide rail 11 is installed on the vehicle, the guide rail 11 is suitable for extending along the length direction of the vehicle. One end of the guide rail 11 close to the inner side of the trunk of the vehicle is fixedly connected to the bottom plate 17, and one end of the guide rail 11 away from the inner side of the trunk is clamped with the bottom plate 17. Thus, after the guide rail 11 is subjected to a large impact force, the end of the guide rail 11 away from the inner side of the trunk of the vehicle is easily separated from the bottom plate 17 and bent at the collapse groove of the guide rail 11. The end of the guide rail 11 close to the inner side of the trunk of the vehicle is fixed relative to the bottom plate 17 and is not easy to invade the interior of the vehicle.

[0121] Specifically, the crush groove is formed at the bottom of the guide rail 11. The length direction of the guide rail 11 is parallel to the length direction of the vehicle, and the crush groove penetrates the guide rail 11 along the width direction of the vehicle.

[0122] In some embodiments, the trunk assist device 10 further includes a blocking structure, which is used to abut against the sliding assembly 12 to limit the sliding distance of the sliding assembly 12 along the guide rail 11. Thus, the sliding distance of the sliding assembly 12 along the guide rail 11 can be limited by the blocking structure to prevent the sliding distance of the sliding assembly 12 along the guide rail 11 from being too large, thereby causing the sliding assembly 12 to fall off the guide rail 11.

[0123] In some embodiments, the trunk assist device 10 may further include a retractable fixed column 18 and a blocking belt 19. The retractable fixed column 18 is disposed above the storage board 16 and is detachably connected to the storage board 16. There are multiple retractable fixed columns 18. The blocking belt 19 is connected to the retractable fixed column 18. Thus, the blocking belt 19 can be used to limit the position of the items on the storage board 16. Moreover, by adjusting the height of the retractable fixed column 18, the height of the blocking belt 19 can be adjusted so that the blocking belt 19 can limit the position of items of different heights.

[0124] The trunk assist device 10 may further include a slide rail 162. The slide rails 162 are arranged in parallel with the guide rail 11 at both ends of the storage board 16. The slide rails 162 extend along the length direction of the guide rail 11, and at least one movable retractable fixing column 18 is arranged on each slide rail 162. Thus, the position of the retractable fixing column 18 along the length direction of the guide rail 11 can be adjusted according to the position of the items on the storage board 16, so that the blocking belt 19 can be more stably abutted against the items on the storage board 16, so as to improve the limiting effect of the blocking belt 19 on the items on the storage board 16.

[0125] The trunk assist device 10 may further include a locking block 181, which is disposed at the lower end of the retractable fixing column 18. The locking block 181 is movably disposed on the slide rail 162 along the length direction of the guide rail 11, and the locking block 181 is used to fix the retractable fixing column 18 on the slide rail 162. Thus, the retractable fixing column 18 and the slide rail 162 can be locked by the locking block 181, so that the position of the blocking belt 19 remains stable, and the limiting effect on the items on the storage plate 16 is better.

[0126] In some embodiments, the lifting assembly 13 can be detachably connected to the storage board 16. Thus, the storage board 16 can be removed from the lifting assembly 13 and used alone. Moreover, when the storage board 16 is damaged, the storage board 16 can be easily removed from the lifting assembly 13 for repair or replacement.

[0127] The lifting assembly 13 may include a connector 1315, and the storage board 16 may include a connecting block 161. One of the connecting block 161 and the connecting member 1315 may be provided with a plug-in slot 1611. The other of the connecting member 1315 and the connecting member 1315 may be provided with a plug-in portion 1316. The plug-in portion 1316 may be inserted into the plug-in slot 1611 to plug the connecting block 161 with the connecting member 1315, so that the lifting assembly 13 and the storage board 16 may be detachably connected. In this way, the connection and separation of the lifting assembly 13 and the storage board 16 may be more convenient.

[0128] It should be noted that the plugging slot 1611 can be provided in the connection block 161, so that the connection member 1315 includes the plugging portion 1316. Alternatively, the connection block 161 can include the plugging portion 1316, and the plugging slot 1611 can be provided in the connection member 1315.

[0129] In some embodiments, a limiting groove 1614 can be opened on the side of one of the plug-in slot 1611 and the plug-in portion 1316, and a positioning protrusion 1317 can be provided on the other of the plug-in slot 1611 and the plug-in portion 1316. The positioning protrusion 1317 is inserted into the limiting groove 1614 to limit the plug-in portion 1316 from falling out of the plug-in slot 1611.

[0130] Therefore, when the plug-in portion 1316 is inserted into the plug-in slot 1611 to plug the connecting block 161 with the connecting member 1315, the positioning protrusion 1317 can be inserted into the limiting slot 1614 to limit the plug-in portion 1316 from escaping from the plug-in slot 1611, thereby making the plug-in between the connecting block 161 and the connecting member 1315 more stable.

[0131] Specifically, a limiting groove 1614 may be provided on the inner side of the plug-in groove 1611 , and a positioning protrusion 1317 may be provided on the outer side of the plug-in portion 1316 . The positioning protrusion 1317 is inserted into the limiting groove 1614 to limit the plug-in portion 1316 from falling out of the plug-in groove 1611 .

[0132] The positioning protrusion 1317 can be made elastic. Therefore, when the plug-in portion 1316 is inserted into the plug-in slot 1611, the positioning protrusion 1317 can be squeezed and deformed, so that the positioning protrusion 1317 enters the plug-in slot 1611, and after the positioning protrusion 1317 moves to a position corresponding to the limiting slot 1614, the positioning protrusion 1317 can return to the initial state and be inserted into the limiting slot 1614. When it is necessary to separate the connecting block 161 and the connecting member 1315, a large pulling force can be applied to make the plug-in portion 1316 withdraw from the plug-in slot 1611, and at this time, the positioning protrusion 1317 will be squeezed and deformed and withdraw from the limiting slot 1614.

[0133] Specifically, the plug-in slot 1611 includes a first sub-slot 1612 and a second sub-slot 1613, and the second sub-slot 1613 extends from the inner side of the first sub-slot 1612 to the outer side of the connecting block 161. The inner side of the first sub-slot 1612 and the inner side of the second sub-slot 1613 are respectively provided with a limiting slot 1614. Thus, the limiting slot 1614 located on the inner side of the first sub-slot 1612 and the inner side of the second sub-slot 1613 can cooperate with the corresponding positioning protrusion 1317 to more effectively limit the plug-in portion 1316 from being disengaged from the plug-in slot 1611.

[0134] In addition, the insertion slot 1611 can be extended along the length direction of the guide rail 11, and one end of the insertion slot 1611 along the length direction of the guide rail 11 has an insertion port for inserting the insertion portion 1316. Thus, by moving the storage plate 16 relative to the connecting member 1315 along the length direction of the guide rail, the insertion portion 1316 can be inserted into the insertion slot 1611, which is very convenient to operate.
