[0032] As shown in the figure, the lifting device 3 also includes a set of first installation boxes 33 and a set of second installation boxes 34. The first installation boxes 33 are installed on the inner walls 11 on both sides of the box body 1, and the second installation boxes 34 are installed on the wall panels 21 on both sides of the pull-out basket 2. The first installation boxes 33 and the second installation boxes 34 are connected by the crank arm assembly 31.

[0033] See also Figure 2 and Figure 3 The first installation box 33 includes a shell 331 , a first rotating shaft 332 and a flange 333 .

[0034] Specifically, a first mounting hole 3311 and a group of arc holes 3312 are provided on the shell 331. The first mounting hole 3311 is arranged between the two arc holes 3312 and is arranged concentrically with the arc holes 3312. The flange 333 is arranged on the inner side of the shell 331, and the first rotating shaft 332 passes through the flange 333 and the first mounting hole 3311 in sequence and is rotatably connected.

[0035] See also Figures 4 to 6 The upper curved arm 311 includes a first mounting portion 3111 , a first connecting portion 3112 and a first bending portion 3113 .

[0036] Specifically, the first mounting portion 3111 is arranged on the inner side of the first mounting box 33 and is connected to the first rotating shaft 332; the first connecting portion 3112 is rotatably connected to the second box body 1, and the two ends of the first bending portion 3113 are respectively connected to the first mounting portion 3111 and the first connecting portion 3112.

[0038] It should be noted that a piston hydraulic rod is connected to the top of the first mounting portion 3111, and a hydraulic rod is also connected to the corresponding positioning pin 334 on the other side of the shell 331. The use of the hydraulic rod can buffer the rotation process of the pull-out basket 2, making the entire movement process of the pull-out basket 2 smoother.

[0039] See also Figures 3 to 5 The first mounting box 33 also includes a second rotating shaft 335 that extends through the housing 331 and is rotatably connected thereto. The synchronization rod 32 is rotatably connected to the first mounting box 33 on either side of the housing 1 via the second rotating shaft 335. The use of the synchronization rod 32 ensures that the rotational amplitudes of the crank arm assemblies 31 at both ends of the synchronization rod 32 remain consistent, thereby improving the rotational stability of the lifting device 3.

[0040] Please continue reading Figures 4 to 6 The lower curved arm 312 includes a second mounting portion 3121 , a second connecting portion 3122 and a second bending portion 3123 .

[0041] Specifically, the second mounting portion 3121 is connected to the synchronization rod 32 through a connecting piece, and the second connecting portion 3122 is rotatably connected to the second mounting box 34; both ends of the second bending portion 3123 are respectively connected to the second mounting portion 3121 and the second connecting portion 3122.

[0042] In addition, a piston hydraulic rod is also connected to the second bending portion 3123, and the effect is the same as above, which will not be repeated here.

[0043] See also Figures 5 to 7 The second mounting box 34 includes an inner sealing plate 341 , an outer sealing plate 342 , a side plate 343 , a third rotating shaft 344 , a fourth rotating shaft 345 and a ratchet gear 346 .

[0044] Specifically, the inner sealing plate 341 is fixedly mounted on the wall panel 21 of the pull-out basket 2. The third rotation axis 344 sequentially passes through the first connecting portion 3112, the outer sealing plate 342, and the inner sealing plate 341, forming a rotatable connection. The fourth rotation axis 345 sequentially passes through the outer sealing plate 342, the second connecting portion 3122, and the inner sealing plate 341, forming a rotatable connection. A ratchet gear 346 is disposed between the inner and outer sealing plates 341, 342, with both ends connected to the second connecting portion 3122 via connectors. The ratchet gear 346 and the fourth rotation axis 345 are coaxially arranged. The side plate 343 is fixedly connected to the inner and outer sealing plates 341, 342, and is provided with an opening 3431.

[0047] Furthermore, the locking portion 3472 is provided with a tooth segment 34721, which meshes with the ratchet gear 346. When the pull-out basket 2 is pulled out of the case 1, the rotation of the ratchet gear 346 is not affected by the tooth segment 34721 and can rotate normally. When the pull-out basket 2 is to be placed into the case 1, the tooth segment 34721 firmly locks the ratchet gear 346, preventing it from rotating. At this point, the lever 3471 is moved upward to disengage the tooth segment 34721 and the ratchet gear 346, allowing the pull-out basket 2 to be smoothly placed into the case 1.

[0048] The design of the tooth segment 34721 can effectively prevent the rebound problem caused by the rotation of the pull-out basket 2, effectively ensure the stability of the pull-out basket 2 during the pulling-out process, and greatly improve the customer experience when using the storage box 1000.

[0049] See also Figure 9 In this embodiment, a storage box 1000 at the rear of a motorhome further includes a box cover 4, which is hingedly connected to the box body 1, and a hydraulic rod is connected between the two.

[0050] The working principle of the storage box 1000 at the rear of a motorhome described in this embodiment is as follows: before the pull-out basket 2 is pulled out of the box body 1, the entire storage box 1000 is as follows: Figure 9 As shown. The user opens the storage box 1000 and lifts the lid 4 upwards. At this point, the basket 2 is still contained within the box body 1 and needs to be pulled out of the box body 1. At this point, the ends of the crank arm assembly 31 begin to rotate, and the entire basket 2, assisted by the lifting device 3, is pulled out of the box body 1 along an arc-shaped path. When the basket 2 reaches the predetermined position, the locking mechanism 347 locks the position of the basket 2, making it easier for the user to remove items from or place items in the basket 2. After placing or removing items, the user swings the lever 3471 on the locking mechanism 347 upwards to disengage the teeth segment 34721 on the locking mechanism 347 from the ratchet gear 346. The user then lifts the basket 2 and places it into the box body 1. Finally, the lid 4 is closed, closing the entire storage box 1000.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
