Description

TECHNICAL FIELD

[0001] The present application relates to the field of luggage, in particular to a luggage. BACKGROUND

[0002] The luggage is a traveling product, which plays a great role in the user's travel. Generally, the luggage has a specific size, so that the luggage can meet the requirements under the corresponding size specification. For example, when taking a plane, the luggage is limited to a box body not greater than 20 inches, so as to ensure that the luggage can be placed in the passenger cabin.

[0003] Usually, the bottom of the luggage is provided with a convex wheel assembly, so as to ensure that the luggage can be pulled and walked without the need of carrying by hand. However, under the fixed volume limitation, the convex wheel assembly reduces the available space inside the luggage. Therefore, how to effectively increase the available space inside the luggage becomes the focus of the luggage design. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a luggage for solving the problem that the convex wheel assembly reduces the available space inside the luggage under the fixed volume limitation.

[0040] Referring to Figures 1 to 4 An embodiment of the present application provides a luggage 100, which comprises a box body 1, the box body 1 comprises a top wall 101, a bottom wall 104, a bevel wall 106 and two side walls 103, the bottom wall 104 is arranged opposite to the top wall 101, the two side walls 103 are arranged on opposite sides of the bottom wall 104 and the top wall 101 respectively, the two side walls 103 are connected with the top wall 101, the two ends of the bottom wall 104 are connected with the two side walls 103 through the bevel wall 106, the bevel wall 106 comprises opposite first and second ends, the first end is connected with the side wall 103, the second end extends away from the top wall 101 and towards one side of the other end side wall 103, and the second end is connected with the bottom wall 104, each bevel wall 106 is connected with at least one wheel assembly 2.

[0041] The first end of the bevel wall 106 is connected with the side wall 103, and the second end is connected with the bottom wall 104, and the second end extends away from the top wall 101 and close to the side wall 103, so that the bevel wall 106 is arranged at an angle with the bottom wall 104 and the corresponding side wall 103, thereby forming a bevel space at the corner where the side wall 103 and the bottom wall 104 are connected. Since the wheel assembly 2 is connected with the bevel wall 106, at least part of the wheel assembly 2 is mounted in the bevel space. Thus, compared with the scheme that the wheel assembly 2 is directly connected with the bottom wall 104, the design can reduce the size of the wheel assembly 2 exposed outside the bottom wall 104, and the bottom wall 104 of the luggage 100 can be lower, so that the height of the box 1 can be higher and the available space in the box 1 can be larger under the fixed volume limit. Therefore, the luggage 100 can effectively increase the available internal space.

[0042] In one embodiment, referring to Figures 1 to 4 , the wheel assembly 2 includes a connecting shaft and a walking wheel 24, one end of the connecting shaft is connected with the bevel wall 106, and the other end is rotatably connected with the walking wheel 24. Thus, the connecting shaft can be accommodated in the bevel space formed by the bevel wall 106, so as to reduce the size of the walking wheel 24 protruding outside the bottom wall 104, thereby making the size of the box 1 larger, which is conducive to increasing the available internal space of the luggage 100. At the same time, since the walking wheel 24 can be reliably connected to the bottom of the box 1 through the connecting shaft, the user can conveniently move the luggage 100 by rolling the walking wheel 24, thereby improving the convenience of using the luggage 100.

[0043] Further, in one embodiment, referring to Figures 1 to 4 , the wheel assembly 2 further includes a support 21, the support 21 is connected with the end of the connecting shaft away from the walking wheel 24, and the support 21 is fixedly connected with the bevel wall 106. Thus, the support 21 can play a role of dispersing local stress and avoiding stress concentration between the connecting shaft and the bevel wall 106. Specifically, the projection of the connecting shaft in the extension direction of the side wall 103 is located in the projection of the support 21 in the extension direction of the side wall 103, that is, the area of the support 21 is larger than the area of the connecting shaft, so that the contact area between the support 21 and the box 1 can be larger than the contact area when the connecting shaft is directly connected with the box 1, and when the walking wheel 24 applies the same force to the connecting shaft, the support 21 can transmit the force to the larger surface of the box 1, so as to achieve the effect of dispersing local stress and avoiding stress concentration, thereby avoiding damage to the box 1 due to stress concentration, and improving the reliability and service life of the luggage 100.

[0044] Optionally, in one embodiment, referring toFigure 5 The side of the support 21 away from the box 1 comprises a first plane 211 and a first inclined plane 212. The first plane 211 is arranged parallel to the bottom wall 104, and one end of the first inclined plane 212 is connected to one end of the first plane 211, and the other end extends to the side close to the bottom wall 104. The first plane 211 is connected to the end of the connecting shaft away from the walking wheel 24. In this way, the first plane 211 can form a platform on the side of the support 21 facing the connecting shaft, which is beneficial to improving the connection stability between the connecting shaft and the support 21, and facilitating the assembly of the connecting shaft to the support 21. The arrangement of the first inclined plane 212 is beneficial to increasing the contact area between the support 21 and the inclined surface, and can also ensure the gap between the support 21 and the walking wheel 24 by using the first inclined plane 212, so as to avoid collision between the first inclined plane 212 and the walking wheel 24 during walking.

[0045] Optionally, in an embodiment, referring to Figure 6 A positioning groove 106a is formed in the inclined wall 106, the groove bottom of the positioning groove 106a is in a stepped shape, and a stepped boss 25 is protrudingly arranged on the side of the support 21 away from the connecting shaft. The stepped boss 25 is fixedly arranged in the positioning groove 106a, and the stepped boss 25 is in abutting fit with the groove bottom of the positioning groove 106a. In this way, the contact area between the support 21 and the box 1 can be increased by the fit between the stepped boss 25 and the groove bottom of the positioning groove 106a, so as to improve the stability of the luggage box 100. In addition, since the abutting surface of the stepped boss 25 and the groove bottom of the positioning groove 106a is in a stepped shape, the damping effect can be achieved by using the stepped abutting surface.

[0046] Optionally, in an embodiment, referring to Figures 1 to 8 The connecting shaft comprises a first rotating shaft 22 and a second rotating shaft 23, and the walking wheel 24 is rotatably sleeved on the outer periphery of the second rotating shaft 23. One end of the first rotating shaft 22 is connected to the second rotating shaft 23, and the other end of the first rotating shaft 22 is rotatably connected to the support 21. In this way, the walking wheel 24 can constitute a universal wheel, which is beneficial to conveniently rotating the luggage box 100 by 360°, thereby improving the convenience of using the luggage box 100.

[0047] Optionally, referring to Figure 5 The first plane 211 of the support 21 is protrudingly provided with a rotating seat 213, and the rotating seat 213 is rotatably connected to the end of the first rotating shaft 22 away from the second rotating shaft 23. In this way, the connection reliability between the support 21 and the first rotating shaft 22 can be improved by the arrangement of the rotating seat 213.

[0048] In an embodiment, referring to Figure 4In the extending direction of the bottom wall 104, the distance D1 between the bottom wall 104 and the side wall 103 is between 70mm and 120mm; in the extending direction of the side wall 103, the distance D2 between the bottom wall 104 and the side wall 103 is between 20mm and 80mm. In this way, the size of the walking wheel 24 protruding from the bottom wall 104 can be effectively shortened to increase the available space of the box 1, and the walking wheel 24 can be ensured not to collide with the bevel wall 106 to ensure that the walking function of the walking wheel 24 can be realized. Specifically, the specific size of the distance D1 and the distance D2 can be selected according to the size of the walking wheel 24, as long as the walking wheel 24 does not interfere with other structural components when walking, and the size of the walking wheel 24 protruding from the bottom wall 104 can be effectively shortened while ensuring that the bottom wall 104 does not contact the ground when the luggage case 100 is being dragged. For example, when the diameter of the walking wheel 24 is 50mm, the distance D1 can be 89mm, and the distance D2 can be 60mm; or when the diameter of the walking wheel 24 is 60mm, the distance D1 can be 90mm, and the distance D2 can be 60mm; at this time, part of the walking wheel 24 can be effectively accommodated in the bevel space to reduce the size of the walking wheel 24 protruding outward, and the walking wheel 24 and the bevel wall 106 (or the first inclined surface 212 of the support 21) have a suitable distance (for example, when the diameter of the walking wheel 24 is 50mm, the distance can be 8mm; when the diameter of the walking wheel 24 is 60mm, the distance can be 9mm) to avoid collision between the walking wheel 24 and the bevel wall 106, and to avoid the distance being too small and easily jamming the walking wheel 24 due to foreign matter, ensuring the reliability of the luggage case 100.

[0049] In one embodiment, the surface of the bottom wall 104 away from the top wall 101 is a lower bottom surface, in the extending direction of the side wall 103, the top end of the walking wheel 24 close to the top wall 101 is higher than the lower bottom surface, and the ratio of the distance D3 between the top end of the walking wheel 24 close to the top wall 101 and the lower bottom surface to the diameter of the walking wheel 24 is less than or equal to 5:12. In this way, the upper end of the walking wheel is higher than the bottom wall, so that part of the walking wheel rises into the bevel space of the bevel wall, which not only effectively shortens the size of the walking wheel 24 protruding from the bottom wall 104 to increase the available space of the box 1, but also ensures that the bottom wall 104 and the ground maintain a certain distance when the luggage case 100 is being dragged by limiting the size of the walking wheel 24 protruding outward from the bottom wall, thereby avoiding friction between the bottom wall 104 and the ground. For example, when the diameter of the walking wheel 24 is 60mm, the size of the walking wheel 24 protruding outward from the bottom wall 104 is 35mm.

[0050] In one embodiment, referring to Figure 1 , Figure 2 , Figure 7 and Figure 8The box 1 comprises a front wall 102 and a rear wall 105, the front wall 102 and the rear wall 105 are respectively connected to two sides of two side walls 103, and are connected with a top wall 101, a bottom wall 104 and a bevel wall 106; the bottom wall 104 comprises a first bottom wall 114 and a second bottom wall 124, the top wall 101 comprises a first top wall 111 and a second top wall 121, the two side walls 103 each comprise a first side wall 113 and a second side wall 123, the bevel wall 106 comprises a first bevel wall 116 and a second bevel wall 126, the front wall 102, the first bottom wall 114, the first top wall 111, the first bevel wall 116 and the two first side walls 113 together form a first shell 11, the rear wall 105, the second bottom wall 124, the second top wall 121, the second bevel wall 126 and the two second side walls 123 together form a second shell 12, the first shell 11 is openably and closably connected with the second shell 12 through an opening and closing assembly 14 to jointly form a containing cavity 1a; the number of the wheel assemblies 2 is four, wherein two wheel assemblies 2 are respectively connected to the two first bevel walls 116, and the other two wheel assemblies 2 are respectively connected to the two second bevel walls 116. In this way, the box 1 is divided into the first shell 11 and the second shell 12, the containing cavity 1a is divided into a first inner cavity formed by the first shell 11 and a second inner cavity formed by the second shell 12, and since the first shell 11 and the second shell 12 can be openably and closably connected, the user can reasonably plan the space of the first inner cavity and the second inner cavity to facilitate the induction and arrangement of articles and improve the user's experience during use. In addition, since the first shell 11 and the second shell 12 are connected with the two wheel assemblies 2, when the luggage 100 stands, the four wheel assemblies 2 can jointly support the box 1 to avoid the luggage 100 from falling due to imbalance.

[0051] Illustratively, in an embodiment, the opening and closing assembly 14 can comprise a zipper, the first shell 11 and the second shell 12 are openably and closably connected through the zipper, in this way, the zipper can conveniently open and close the box 1 to improve the convenience of the luggage 100 during use; in other embodiments, the opening and closing assembly 14 can also comprise a first lock and a second lock which is locked with the first lock, the first lock is arranged on the first shell 11, and the second lock is arranged on the second shell 12, in this way, when the first lock and the second lock are locked, the first shell 11 and the second shell 12 can be locked to prevent the articles in the containing cavity 1a from being scattered, and when the first lock and the second lock are separated, the box 1 can be conveniently opened to facilitate the loading of articles into the containing cavity 1a or the taking of articles in the containing cavity 1a.

[0052] Further, in an embodiment, referring to Figure 1 , Figure 2 , Figure 7 and Figure 8The box 1 comprises a folding part 13, one end of the folding part 13 is connected with the first shell 11, and the other end is connected with the second shell 12 through the opening and closing assembly 14 in an openable and closable manner to jointly form the accommodating cavity 1a. The folding part 13 has a folded state and an unfolded state. In the folded state, the folding part 13 is accommodated between the first shell 11 and the second shell 12. In the unfolded state, the distance between the first shell 11 and the second shell 12 can be increased to increase the accommodating cavity 1a. In this way, the luggage 100 can simultaneously meet the normal use and the storage saving requirement through the unfolding and folding of the folding part 13. Specifically, when the folding part 13 is in the unfolded state, the folding part 13 can be unfolded to jointly enclose the surface of the box 1 with the first shell 11 and the second shell 12, thereby increasing the distance between the first shell 11 and the second shell 12, increasing the volume of the accommodating cavity 1a, realizing the expansion of the accommodating cavity 1a, and facilitating the placement of more articles. At this time, the luggage 100 is in a normal use state. When the folding part 13 is in the folded state, the folding part 13 is accommodated between the first shell 11 and the second shell 12, so the surface of the box 1 is jointly enclosed by the first shell 11 and the second shell 12 at this time. The distance between the first shell 11 and the second shell 12 is reduced, which reduces the volume of the box 1. At this time, the luggage 100 is in a storage state of saving storage space. Since the opening and closing assembly 14 is arranged between the folding part 13 and the second shell 12, the box 1 can open or close the accommodating cavity 1a through the opening and closing assembly 14 regardless of whether the folding part 13 is in the folded state or the unfolded state, so that the box 1 can form a complete whole structure.

[0053] In addition, referring to Figure 2 and Figure 8Since the first end of the bevel wall 106 is connected with the side wall 103, and the other end extends to the side away from the top wall 101 and close to the other side wall 103 and is connected with the bottom wall 104, the included angle between the bevel wall 106 and the bottom wall 104 and the included angle between the bevel wall 106 and the side wall 103 are both greater than 90°, which makes the zipper can be directly sewn on the bottom wall 104, the bevel wall 106 and the side wall 103 when the opening and closing assembly 14 is the zipper, and the problem of not easy to adjust the needle direction during the sewing process due to the too small included angle. Therefore, the first bevel wall 116 can extend from the connection with the front wall 102 to the opening edge of the first shell 11, and the second bevel wall 126 can extend from the connection with the rear wall 105 to the opening edge of the second shell 12, that is, the bevel space at the bottom of the first shell 11 penetrates from the side of the first shell 11 away from the second shell 12 to the opening edge of the first shell 11, and the bevel space at the bottom of the second shell 12 penetrates from the side of the second shell 12 away from the first shell 11 to the opening edge of the second shell 12. Therefore, compared with the scheme of opening a groove for accommodating the wheel assembly 2 on the bottom wall 104, this design does not need to set a transition wall between the groove edge and the shell edge to ensure that the corner between the side wall 103 and the bottom wall 104 is large enough, so that the size of the first side wall 113 of the first shell 11 and the size of the second side wall 123 of the second shell 12 can be smaller, thereby making the whole luggage 100 can be thinner when in the storage state, and the occupied storage space can be smaller.

[0054] Illustratively, the folding part 13 can be a flexible piece, for example, a cloth piece, so that the luggage 100 can change its size by pushing and pulling the folding part 13.

[0055] Further, in one embodiment, referring to Figure 9The box 1 further comprises a folding plate 17 movably arranged in the accommodating cavity 1a, one end of the folding plate 17 is rotatably connected with the first shell 11, and the other end is a free end, the folding plate 17 is provided with a first locking member 171, the folding part 13 is provided with a second locking member 131, and the folding plate 17 has a supporting position and a storage position. In the supporting position, the free end extends towards the side close to the second shell 12, the first locking member 171 and the second locking member 131 are locked and matched, so that the folding plate 17 can support the folding part 13 and the folding part 13 is maintained in the unfolded state; in the storage position, the first locking member 171 and the second locking member 131 are unlocked, the folding plate 17 is stored in the first shell 11, and the folding part 13 is folded to the folded state. In this way, when the folding plate 17 is in the supporting position, the folding plate 17 can maintain the folding part 13 in the unfolded state away from the first shell 11 under the action of the first locking member 171 and the second locking member 131, so that the folding part 13 can effectively increase the volume of the accommodating cavity 1a, and the luggage box 100 can be stably maintained in the state of normal use with a larger volume, so as to better meet the use requirements of the user. At the same time, the folding plate 17 can also support the folding part 13 on the inner side of the folding part 13, so that the folding part 13 can resist a certain external impact force. When the locking between the first locking member 171 and the second locking member 131 is released, the interaction between the folding plate 17 and the folding part 13 will be invalid, which makes the folding plate 17 rotate to the storage position in the first shell 11, and the folding part 13 can be folded and stored in the first shell 11, so as to reduce the distance between the first shell 11 and the second shell 12, and save the required storage space of the luggage box 100.

[0056] Illustratively, one of the first locking member 171 and the second locking member 131 is an elastic rope, and the other is a positioning hook; or one of the first locking member 171 and the second locking member 131 is a lock hook, and the other is a lock catch matched with the lock hook; or one of the first locking member 171 and the second locking member 131 is a magnetic attraction member, and the other is a suction member magnetically attracted to the magnetic attraction member.

[0057] Optionally, in one embodiment, referring to Figure 9, a first frame 132 is arranged between the folding part 13 and the first shell 11, one end of the folding plate 17 is rotatably connected with the first frame 132, a second frame 133 is arranged on the side of the folding part 13 away from the first shell 11, the second locking member 131 is arranged on the second frame 133, and the second frame 133 is openably and closably connected with the second shell 12 through the opening and closing assembly 14. In this way, when the folding plate 17 rotates relative to the first frame 132 and the first locking member 171 is locked with the second locking member 131, the folding plate 17 can be linked with the folding part 13 to make the folding part 13 open and maintain in the unfolded state. In addition, since the folding part 13 is a flexible part that can be folded, the folding part 13 is connected with the opening and closing assembly 14 and the first shell 11 through the frame, which is conducive to increasing the connection reliability.

[0058] Optionally, in an embodiment, referring to Figure 1 and Figure 7 , the outer side of the first shell 11 is provided with a first fixing member 11a, and the second shell 12 is provided with a second fixing member 12a that is detachably connected with the first fixing member 11a, and the first fixing member 11a and the second fixing member 12a are used to lock the first shell 11 and the second shell 12 in the folded state. In this way, when the folding part 13 is in the folded state, the folding part 13 can be maintained in the folded state through the locking of the first fixing member 11a and the second fixing member 12a, and the box body 1 can be maintained in the storage state with a smaller volume, so that the luggage 100 occupies a smaller space.

[0059] Illustratively, one of the first fixing member 11a and the second fixing member 12a can be an elastic rope, and the other can be a positioning hook; or one of the first fixing member 11a and the second fixing member 12a is a lock hook, and the other is a lock buckle, and the lock hook and the lock buckle are engaged and matched.

[0060] Optionally, in an embodiment, referring to Figure 7 and Figure 9 , the box body 1 is provided with a handle 15, and the handle 15 is arranged on the outer side of the first shell 11 or the folding part 13. In this way, when the luggage 100 is used, the user can conveniently lift the box body 1 through the handle 15, which is conducive to improving the portability of the luggage 100.

[0061] Illustratively, when the handle 15 is arranged on the first shell 11, the handle 15 can be arranged on the top wall 101 or the side wall 103; and when the handle 15 is arranged on the folding part 13, the handle 15 can be a flexible part, so that in the folded state, the handle 15 can be easily stored in the first shell 11, and the handle 15 will not have a rigid abutment with the first shell 11, which is conducive to improving the reliability of the first shell 11.

[0062] Optionally, in an embodiment, referring to Figure 1 ,Figure 3 、 Figure 7 and Figure 9 The first shell 11 is further provided with a pull rod slot, and the luggage 100 further comprises a pull rod 16 which is telescopically arranged in the pull rod slot.
