Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] This utility model relates to an assisted pull-along suitcase, such as Figures 1-4 As shown, the device includes a housing 100, a power-assisted drive unit 101 installed inside the housing 100 and extending to the outside, and a walking wheel 102 installed at the bottom of the housing 100 and the power-assisted drive unit 101. An extension component 200 is connected to the side surface of the housing 100, and a fixing component 300 is provided between the extension component 200 and the housing 100. A support component 400 for supporting the extension component 200 is installed on the inner wall of the housing 100.
[0028] The extension assembly 200 includes a hinge 201 connected to the side surface of the housing 100 and an extension plate 202 connected to the side surface of the hinge 201 and fitted into the inner wall of the side surface of the housing 100. When the extension plate 202 is pulled, it rotates around the central axis of the hinge 201. After the extension plate 202 rotates 90°, the area of the top of the housing 100 can be increased.
[0029] Furthermore, the fixing component 300 includes a slot 301 formed at the end of the extension plate 202 and a rubber strip 302 connected to the side surface of the housing 100. When the bottom of the extension plate 202 drives the slot 301 to engage with the surface of the rubber strip 302, the position of the extension plate 202 can be fixed by the engagement of the rubber strip 302 with the slot 301.
[0030] Furthermore, the support assembly 400 includes a bearing seat 401 mounted on the side surface of the housing 100, a rotating shaft 402 extending through and connected inside the bearing seat 401, a first extension arm 403 connected to the side surface of the rotating shaft 402, a first upright 404 connected to the other end of the first extension arm 403, a bearing ring 405 sleeved in the middle of the first upright 404, a first screw 406 connected to the top of the first upright 404, a first threaded sleeve 407 sleeved on and adapted to the surface of the first screw 406, a second extension arm 408 connected to the surface of the bearing ring 405, a second column 409 connected to the other end of the second extension arm 408, a second screw 411 connected to the top of the second column 409, and a second threaded sleeve 410 sleeved on and adapted to the surface of the second screw 411.
[0031] Furthermore, the support assembly 400 also includes a third screw 412 connected to the inner surface of the extension plate 202 and having the same dimensions as the first screw 406, and a fourth screw 413 connected to the inner surface of the extension plate 202 and having the same dimensions as the third screw 412.
[0032] Furthermore, after the rotating shaft 402 drives the first screw 406 to rotate 90° away from the housing 100 via the first extension arm 403 and the first upright 404, the central axis of the first screw 406 and the third screw 412 are in the same position. After the second extension arm 408 drives the second screw 411 to rotate 90° away from the housing 100 via the second upright 409, the central axis of the second screw 411 and the fourth screw 413 are in the same position.
[0033] In use, firstly, pull the extension plate 202 to rotate around the central axis of the hinge 201. Then, pull the first extension arm 403 to drive the rotating shaft 402 to rotate inside the bearing seat 401. At the same time, the first extension arm 403 drives the first screw 406 to rotate 90° away from the housing 100 through the first upright 404. At this time, the first threaded sleeve 407 can be rotated. When the first threaded sleeve 407 rotates, it moves upward on the surface of the first screw 406 through the threaded connection. When the first threaded sleeve 407 moves to the bottom of the third screw 412, it can move upward on the surface of the third screw 412 as it continues to rotate. When the first threaded sleeve 407 is fitted at the connection between the first screw 406 and the third screw 412, the first upright 404 can be connected.
[0034] Next, pulling the second column 409 causes the second extension arm 408 to rotate 90° away from the housing 100 around the central axis of the bearing ring 405. At this time, the second threaded sleeve 410 can be rotated. While rotating on the surface of the second screw 411, the second threaded sleeve 410 can move upward. When the second threaded sleeve 410 moves upward to the bottom of the fourth screw 413, continuing to rotate the second threaded sleeve 410 can move upward on the surface of the fourth screw 413. When the second threaded sleeve 410 is fitted at the connection between the second screw 411 and the fourth screw 413, the second column 409 can be docked. Thus, the extension plate 202 can be supported by the support assembly 400. The extension plate 202 can increase the area of the top of the trolley case.
[0035] Example 2
[0036] like Figure 1 , Figures 5-7 The second embodiment of the present invention is shown, which differs from the first embodiment in that: a suspension component 500 is provided on the side of the housing 100 away from the extension component 200, and the suspension component 500 is connected to the housing 100 through a rotating component 600.
[0037] The suspension assembly 500 includes a hanging rod 501 located on one side of the case 100 and a hook 502 attached to the surface of the hanging rod 501. After the suspension assembly 500 is rotated 90°, the hook 502 on the surface of the hanging rod 501 can be used to hang shopping bags, so that items needed during the trip can be hung on the outside of the case 100 for easy access without opening the case 100.
[0038] Furthermore, the rotating assembly 600 includes a horizontal shaft 601 connected to both sides of the housing 100, a limiting half-ring 602 connected to the surfaces of the two horizontal shafts 601 respectively, a limiting ring 603 connected to the surfaces of the horizontal shafts 601 respectively, a rotating sleeve 604 sleeved on the surfaces of the horizontal shafts 601 and located between the limiting half-rings 602 and the limiting half-rings 602, and a spring strip 605 connected to the side surface of the rotating sleeve 604 and connected to the housing 100.
[0039] Furthermore, the protrusion of the rotating sleeve 604 is located on the upper part of the limiting semi-ring 602, and the maximum rotation angle of the rotating sleeve 604 on the horizontal axis 601 is 90°.
[0040] In use, pulling the hanging rod 501 will cause the rotating sleeve 604 to rotate on the surface of the horizontal shaft 601. When the rotating sleeve 604 rotates 90°, its protrusion moves to the other side of the limiting half ring 602. At this time, the rotating sleeve 604 stops rotating. At the same time, the rotation of the rotating sleeve 604 pulls the spring strip 605 to deform. At this time, the item can be hung on the surface of the hook 502. When the item is no longer needed, the hanging rod 501 can be released. At this time, the spring strip 605 will recover its deformation through its own elasticity and drive the rotating sleeve 604 to reset. The reset of the rotating sleeve 604 can drive the hanging rod 501 to reset.
[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
