DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The present invention provides an electric luggage case, such as Figures 1 to 3 As shown, it includes a case body 1, a drive assembly 10, and a handle assembly. By cleverly designing the installation positions of the components, the added drive assembly 10 and handle assembly will not occupy too much storage space of the case body 1, thereby ensuring the main storage function of the suitcase. At the same time, the retracted storage of the drive assembly 10 and the handle assembly is more adapted to the structure of the case body 1, will not cause storage obstacles, and can also protect the drive assembly 10, thereby extending the service life of the electric suitcase and making it more practical.

[0031] The box body 1 has a slot 11 formed on the outer side thereof, a through slot 12 penetrating into the box body 1 is formed at the lower part of the slot 11, and an opening door 13 of the box body 1 is arranged on the other side thereof to avoid the slot 11; the driving assembly 10 comprises a wheel set 101 installed at the bottom, a transverse telescopic rod 102 arranged above the wheel set 101 and extending out of the through slot 12, a driving member for driving the transverse telescopic rod 102 to extend and retract, a first control member 103 electrically connected to the driving member, and a power supply 104 electrically connected to the first control member 103; the first control member 103 and the power supply 104 are connected to each other. The driving member is installed in the box body 1 on the opposite side of the slot 11; the handle assembly includes a vertical telescopic rod 2 connected to one side of the horizontal telescopic rod 102 and connected to the wheel set 101, and a foldable handle member 3 installed on the top of the vertical telescopic rod 2; a second control member (not shown in the figure) electrically connected to the power supply 104 is installed in the handle member 3, and the second control member is used to regulate the movement of the electric suitcase; wherein, when the horizontal telescopic rod 102 is retracted, the vertical telescopic rod 2 is driven to be stored back in the slot 11, and the two sides of the handle member 3 are folded and vertically stored in the slot 11.

[0032] The transverse telescopic rod 102 is telescoped inside and outside the case 1 with the help of the through slot 12. When the suitcase is electrically driven to move, the transverse telescopic rod 102 extends out of the through slot 12, so that a certain distance is maintained between the vertical telescopic rod 2 and the case 1, so that the movement of the wheel set 101 is not hindered and the movement is smoother; at the same time, the upper surface of the suitcase can also serve as a seat, and the user can sit on the upper surface of the suitcase and move forward with the suitcase, making travel easier.

[0033] Although some electric luggage cases can also realize the function of carrying people, their structural design is unreasonable. The driving assembly 10 is often installed in a certain area at the bottom of the box 1. After the user has stored the luggage, the force on the entire luggage case is often unbalanced. The wheel set 101 is also simply composed of 2 to 3 wheels. When the user sits on the box 1, it is very easy to overturn or fall during the movement. Many such incidents have occurred, which is very dangerous. In the electric luggage case of the present invention, the first control member 103 and the power supply 104 in the driving assembly 10 are installed in the outer notch 11, and the driving member is installed in the box 1 on the opposite side of the notch 11, that is, the first control member 103 and the power supply 104 are respectively installed with the driving member at the two side ends of the box 1, forming a triangular structure, and the load-bearing capacity of the bottom is greatly enhanced. Even if the weight of the objects stored in the box 1 is not evenly distributed, there is no risk of overturning after the user sits on the box 1, and the safety is high.

[0034] In some embodiments, the first control member 103 and the power source 104 are respectively installed on both sides of the slot 11, the horizontal telescopic rod 102 is clamped between the first control member 103 and the power source 104 when extended, the vertical telescopic rod 2 is clamped between the first control member 103 and the power source 104 after retracting, and the handle member 3 is respectively located above the first control member 103 and the power source 104 after folding. The components are compactly arranged in structure, and the slot 11 has a high utilization rate, which can reduce the occupation of the storage space of the box body 1 to a greater extent, and ensure the storage utilization rate of the box body 1.

[0035] The state of the electric luggage case of the present invention when stored: the vertical telescopic rod 2 is retracted into the notch 11 and clamped between the first control member 103 and the power source 104. After the handle member 3 is folded, the two sides of the handle member 3 are vertically located above the first control member 103 and the power source 104. It can be seen that the components basically do not exceed the design of the case 1. Compared with some electric luggage cases with strange shapes, the electric luggage case of the present invention can maintain a shape similar to that of a non-electric luggage case, and the overall structure is square and easier to place when stored.

[0036] In addition, the electric luggage case of the present invention can also be used as a conventional non-electric luggage case. The vertical telescopic rod 2 is retracted into the slot 11 and clamped between the first control member 103 and the power source 104, but the two sides of the handle member 3 are still laterally exposed outside the case 1. The user can pull the handle member 3 to manually push the luggage case, which is consistent with the use state of a conventional non-electric luggage case. Compared with some electric luggage cases that require additional pull rods, the electric luggage case of the present invention has a reasonable weight distribution, and the handle assembly has sufficient load-bearing capacity to be manually pushed and pulled, thereby ensuring that the handle assembly can achieve this function, and has greater versatility.

[0037] The extension process when used as an electric suitcase is as follows: the driving member is activated by the button of the first control member 103, and the driving member drives the horizontal telescopic rod 102 to extend along the through slot 12, and extends the vertical telescopic rod 2 and the handle member 3 together. After reaching the specified extension position, the two sides of the handle member 3 are unfolded to be placed horizontally, and the vertical telescopic rod 2 can also be adjusted in height according to usage requirements, thereby completing the pre-working mode of the electric suitcase, and then the user can realize the movement control of the suitcase by operating the second control member of the handle member 3. The movement control may include forward, backward and other operations. These operating functions can be referred to conventional electric suitcases and will not be repeated here.

[0038] In some embodiments, Figure 2As shown, first slide grooves are arranged on both sides of the transverse telescopic rod 102, and bars 121 matching the first slide grooves are arranged at the through groove 12 corresponding to the first slide grooves. The cooperation between the first slide grooves and the bars 121 can make the extension and retraction movement of the transverse telescopic rod 102 smoother.

[0039] In some embodiments, the shortest height of the handle assembly is 0.8 to 1 of the height of the box body 1. The shortest height of the handle assembly here refers to the sum of the shortest height of the vertical telescopic rod 2 and the height of the handle member 3. Controlling the shortest height of the handle assembly can ensure that the handle assembly is completely stored back in the slot 11. In addition, the top of the first control member 103 is also controlled to be flush with the top of the power source 104. Setting the two flush makes it easier to leave enough space for the handle 32 to be folded and recovered.

[0040] The length of the vertical telescopic rod 2 can be freely adjusted. Preferably, the vertical telescopic rod 2 can be composed of 2 to 3 pull rods, which can better meet the different usage requirements of users.

[0041] In some embodiments, a baffle (not shown) is provided on the front side of the vertical telescopic rod 2, and the baffle blocks the front side of the slot 11 after the vertical telescopic rod 2 is retracted between the first control member 103 and the power source 104. By adding the baffle, when the vertical telescopic rod 2 is retracted into the slot 11, the baffle can block the opening 41 of the slot 11, which is more helpful to protect the drive assembly 10 on the one hand, and more square and beautiful in overall appearance on the other hand.

[0042] In some embodiments, Figures 4 to 6 As shown, the handle member 3 includes a mounting portion 31 fixedly connected to the vertical telescopic rod 2, and handles 32 are arranged on both sides of the mounting portion 31. The handles 32 on both sides are vertically stored in the slot 11 after being folded and are respectively located above the first control member 103 and the power supply 104; slots 4 are provided on both sides of the mounting portion 31, and connecting portions 5 plugged into the slots 4 are fixedly provided on the handles 32, the connecting portions 5 are connected to the slots 4, and an opening 41 is provided at the lower end of the slots 4, and a fixing structure 6 is provided between the mounting portion 31 and the handles 32.

[0043] By opening an opening 41 at the lower end of the slot 4, the two handles 32 can be folded vertically downward and can be stored in the slot of the suitcase together with the mounting frame, which will not occupy too much space in the suitcase and is convenient to fold and store. At the same time, the position of the handles 32 is fixed by the fixing structure 6 to prevent them from loosening and folding during riding and causing safety accidents.

[0044] Furthermore, the fixing structure 6 includes a positioning sleeve 61 slidably disposed on the handle 32, and the positioning sleeve 61 is plugged into the mounting portion 31; when the positioning sleeve 61 fixes the handle 32, the positioning sleeve 61 is simultaneously covered on the outside of the mounting portion 31 and the handle 32, so that the angle of the handle 32 cannot be changed, thereby achieving fixation of the handle 32.

[0045] The two sides of the mounting portion 31 are fixedly provided with limiting portions 62, the positioning sleeve 61 is plugged into the limiting portions 62, and there are two limiting portions 62, which are symmetrically arranged along the central axis of the slot 4. A path for the connecting portion 5 to slide is formed between the limiting portions 62, and the path is perpendicular to the ground, so that the two handles 32 can be folded vertically downward.

[0046] In addition, the handle 32 is provided with a reset structure 7 that cooperates with the positioning sleeve 61, the second control member is installed on the outside of the reset structure 7, a second slide groove is opened in the handle 32, and a guide groove 71 that cooperates with the second slide groove is opened on the handle 32. The inner wall of the positioning sleeve 61 is fixedly provided with a guide portion 72 that cooperates with the guide groove 71; a part of the guide portion 72 is inserted into the interior of the slide groove along the guide groove 71 to limit the moving trajectory of the positioning sleeve 61 and prevent it from falling off the handle 32.

[0047] The guide portion 72 is fixedly provided with a sliding portion 73 matched with the second slide groove, and a tension spring 74 is provided between the sliding portion 73 and the second slide groove. The tension spring 74 is provided to drive the guide portion 72 and the positioning sleeve 61 to move, so that the positioning sleeve 61 is in close contact with the limiting portion 62 to prevent loosening, thereby preventing the handlebar 32 from folding during riding.

[0048] More specifically, a positioning glass bead 8 is fixedly provided on the handle 32, and a guide groove 9 matching the positioning glass bead 8 is opened on the positioning sleeve 61. When the positioning sleeve 61 is plugged into the limiting portion 62, the positioning glass bead 8 contacts the positioning sleeve 61 to prevent the positioning sleeve 61 from moving and separating from the limiting portion 62. The positioning sleeve 61 can be moved and the handle 32 can be folded by pressing the positioning glass bead 8. When the positioning sleeve 61 needs to be plugged into the limiting portion 62, the positioning glass bead 8 contacts the guide groove 9 and is pressed, so that the movement of the positioning sleeve 61 will not be hindered.

[0049] The working mode of the handle assembly of the present invention is as follows: when working, the two handles 32 can be folded vertically downward by opening the opening 41 at the lower end of the slot 4, and the positioning sleeve 61 is moved to be plugged into the limiting portion 62. During this process, the positioning glass bead 8 is pressed in contact with the guide groove 9, so that the movement of the positioning sleeve 61 is not hindered. When the positioning sleeve 61 is plugged into place, the positioning glass bead 8 is in contact with the positioning sleeve 61 to prevent the positioning sleeve 61 from moving and separating from the limiting portion 62.

[0050] When folding the handle 32, the positioning glass bead 8 is pressed to move the positioning sleeve 61 to fold the handle 32. During the process, the tension spring 74 is stretched and elastically deformed, and the handle 32 is rotated and folded to a right angle with the mounting portion 31. Under the action of the tension spring 74, the positioning sleeve 61 and the mounting portion 31 abut against each other to limit the position of the handle 32, thereby preventing the angle from changing and facilitating the connection of the handle 32 frame to the box body 1.

[0051] In some embodiments, the wheel set 101 structure includes a balancing wheel set 1011 installed at the bottom of the box body 1, an auxiliary wheel set 1013 installed at the lower end of the vertical telescopic rod 2, and a power wheel 1012 installed between the balancing wheel set 1011 and the auxiliary wheel set 1013, and the balancing wheel set 1011 and the auxiliary wheel set 1013 are kept level with the bottom edge of the power wheel 1012 through the adjustment member 1014. Among them, the power wheel 1012 is used to provide power for the movement of the entire box body 1, and the power wheel 1012, two balancing wheels, and two auxiliary wheel sets 1013 form five wheels, which are evenly distributed at the bottom of the box body 1. With the first control member 103, the power source 104, and the drive member structure distribution, the bottom balance of the electric luggage case is better, and users have better stability when sitting on the box and exercising.

[0052] Furthermore, the auxiliary wheel set 1013 is installed on the lower end of the vertical telescopic rod 2 through an adjusting member 1014 , and when the vertical telescopic rod 2 is stored back into the notch 11 , the adjusting member 1014 is located at the bottom of the box 1 .
