Description:
CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application is based on Chinese Patent Application No. 201521132259.8 filed on Dec. 30, 2015, the disclosure of which is incorporated herein by reference in its entirety. 
       TECHNICAL FIELD 
       [0002]    The present application relates to the field of cases and bags, and particularly to a suitcase. 
       BACKGROUND ART 
       [0003]    At present, with the rapid pace of social life and the progress of economy, science, and technology, people travel more frequently. Tourisms, vacation aboard, business trips, friend visiting, off-site learning, home-returning and so on are very common. As more travels are needed, suitcases for storing goods become essential items for people. 
         [0004]    The size of the suitcase becomes increasingly large since a lot of luggage items are needed for traveling. When many items are cased, the internal items need to be compressed and fixed. At present, it is a common practice to additionally provide separating plate(s) inside an internal chamber of the suitcase to divide a storage chamber into a plurality of spaces, which can serve a storing function. 
         [0005]    The inventor has found from researches that in the prior art, the separating plate is fixed at three points, wherein the separating plate is opened up in a direction from a bottom of a case body to a top of the case body, however, such an opening manner makes the separating plate not supported during the opening process, and the separating plate has to be totally flipped out to be in contact with the ground, causing the separating plate to get soiled. Moreover, such an opening manner is not favorable for a user&#39;s operation since the user has to continuously change his/her position with respect to the case body for opening the separating plate and closing the separating plate. 
       Disclosure of the Application 
       [0006]    An object of the present application is to provide a suitcase to improve the storing capacity of a suitcase in the prior art. 
         [0007]    The present application is implemented as follows: 
         [0008]    a suitcase, comprising case bodies and separating plates, 
         [0009]    wherein the case bodies comprise an upper case body and a lower case body which are rotationally connected, the upper case body and the lower case body are capable of forming a storage chamber, the separating plates comprise an upper separating plate and a lower separating plate, the upper separating plate is provided in the upper case body, and the lower separating plate is provided in the lower case body; 
         [0010]    in a state of the case bodies being open, the upper separating plate is capable of rotating toward a direction of the lower case body, and the lower separating plate is capable of rotating toward the upper case body. 
         [0011]    The storage chamber of the case bodies is divided into several spaces by the added upper separating plate and lower separating plate, and the spaces after the division are more compact in volume, facilitating fixing the luggage. The upper case body and the lower case body are opened and closed by rotating, the upper separating plate and the lower separating plate are respectively rotationally connected in the upper case body and the lower case body, and both separating plates are capable of rotating toward the middle, facilitating the support and control, and making it easy for a user to take out luggage from or put the luggage into the storage chamber. 
         [0012]    Further, the separating plate and the case body are connected by a connecting belt set, and there are two connecting belt sets which are respectively connected into the lower case body and the upper case body; 
         [0013]    the case body comprises a first sidewall and a second sidewall which are opposite to each other, a rotation center line between the upper case body and the lower case body is provided on the second sidewall, each of the connecting belt sets comprises a first belt set and a second belt set, the separating plate is detachably connected with the first sidewall through the first belt set, and the separating plate is rotationally connected with the second sidewall through the second belt set; 
         [0014]    a side of the separating plate far away from the second sidewall is a first side edge and a side of the separating plate close to the second sidewall is a second side edge; 
         [0015]    when the first belt set is in a state of being separated from the separating plate, the upper separating plate and the lower separating plate are capable of rotating, and the first side edge of the upper separating plate and the first side edge of the lower separating plate abut against each other during rotation. 
         [0016]    By connecting the separating plate with the connecting belt set, rotation of the separating plate is facilitated. The first belt set and the second belt set connect two sides of the separating plate with the first sidewall and the second sidewall respectively. The second sidewall is the region where rotating axes of the lower case body and the lower case body are located, and the first sidewall is a sidewall on the case body directly facing the second sidewall. The upper separating plate and the lower separating plate both are fixed on the case bodies through the connection with the second sidewall and the first sidewall, facilitating removing or installing the separating plates. The upper separating plate and the lower separating plate both can be disconnected from the first belt set and movably connected with the case bodies through the second belt set. When the upper separating plate and the lower separating plate are disconnected from the first belt set, the first side edges of the upper separating plate and the lower separating plate can rotate, and during the rotating process, the first side edges of the upper separating plate and the lower separating plate abut against each other such that the two separating plates can remain erected, with the second sidewall located between the two separating plates. The storage chamber is completely exposed when the two separating plates are erected, making it convenient for the user to put luggage into the upper case body and the lower case body. By such a connection manner, the user can erect or lay down the separating plate without changing his/her position with respect to the suitcase, facilitating operations. Meanwhile, the separating plates will not be flipped away from the storage chamber or be in contact with the ground. 
         [0017]    Further, the upper separating plate and the lower separating plate both are detachably connected with the second belt set. 
         [0018]    The separating plate and the second belt set also can be detachably connected with each other, making it easy for the user to detach the separating plate to clean the suitcase. 
         [0019]    Further, the detachable connection is in a mode of a Velcro connection or button connection. 
         [0020]    Velcro and buttons are common modes of detachable connection. The Velcro is easily used and can be used repeatedly, facilitating adjusting the connection position; the button, allowing precise location, is simple in use. 
         [0021]    Further, the upper separating plate and the lower separating plate are respectively provided with a loop surface and a hook surface of the Velcro, and when the first side edge of the upper separating plate and the first side edge of the lower separating plate abut against each other, the loop surface and the hook surface are in contact with each other. 
         [0022]    The upper separating plate and the lower separating plate are provided with corresponding Velcro. The two separating plates, when abutting against each other to erect, are fixed through adhesion of the loop surface and the hook surface of the Velcro, making it convenient to enable the two separating plates to maintain the erected state. 
         [0023]    Further, each of the connecting belt sets further comprises a connecting section, the first belt set and the second belt set are both connected or integrally formed with the connecting section, and the connecting section is used for fixing or compressing luggage. 
         [0024]    The connecting section is used for tying the luggage into the suitcase. The luggage is pre-compressed into the storage chamber by the connecting section, and then the luggage is further compressed by the separating plate, preventing small items from moving freely in the storage chamber, at the same time, the utilization ratio of the storage chamber can be improved since the loose and soft luggage is compressed in volume so that the case body is capable of storing more luggage items. 
         [0025]    Further, the connecting section is in a shape of a triangle having two endpoints located on the second sidewall and another endpoint located on the first sidewall. The first belt set and the second belt set are fixed at the endpoints respectively. 
         [0026]    The triangular area formed by the connecting section is capable of reliably limiting the position of the luggage, and all of the three endpoints of the triangle are located on the second sidewall and the first sidewall so that the connecting section requires a relatively short length. 
         [0027]    Further, the connecting belt set is fixed with the case body at three endpoints of the triangle. 
         [0028]    The connecting belt set is fixedly connected with the case body only through regions of the three endpoints, such that luggage can be placed and fixed in intermediate sections of the connecting belt sets. 
         [0029]    Further, the connecting sections of the two connecting belt sets are respectively provided in a gap between the upper separating plate and the upper case body and a gap between the lower separating plate and the lower case body. 
         [0030]    The separating plate and the luggage, located at two sides of the connecting section respectively, do not interfere with each other when putting in the luggage. 
         [0031]    Further, the separating plate is in a quadrilateral shape, and four corners of the separating plate are provided with a notch respectively. 
         [0032]    Four corners of the separating plate are provided with the notch, facilitating providing the separating plates into the upper case body and the lower case body. Because a joint of the sidewalls of the case bodies may be provided with chamfers or rounded angles and an internal space of the case body may be occupied when universal wheels are provided at the bottom of the case body, all of the four corners of the separating plate are provided with the notch making it easy to be adapted to spatial dimensions. 
         [0033]    The beneficial effects of the present application are as follows: a connecting belt set is provided inside the case body and the separating plate is limited by the connecting belt set, making it easy to adjust a position of the separating plate, and it is not needed to remove the separating plate when loading the luggage or taking out the luggage, which is more convenient. The upper case body and the lower case body are opened and closed by rotating, and the upper separating plate and the lower separating plate are respectively connected to the upper case body and the lower case body by the connecting belt sets, making it convenient for the user to take out the luggage from or put the luggage into the storage chamber. Furthermore, the two separating plates, when opened, can be enabled to abut against each other and erect, such that a user can more easily adjust the state of the separating plates.

         [0050]    The case body includes a first sidewall  108  and a second sidewall  109  which are opposite to each other, and a rotation center line between the upper case body  101  and the lower case body  102  is provided on the second sidewall  109 . 
         [0051]    There are two connecting belt sets, and the lower case body  102  and the upper case body  101  are each provided with one set therein. 
         [0052]    Each connecting belt set includes a connecting section  107 , a first belt set  105 , and a second belt set  106 , and the separating plate is connected with the first sidewall  108  through the first belt set  105 , and is connected with the second sidewall  109  through the second belt set  106 . 
         [0053]    The first belt set  105  and the second belt set  106  connect two sides of the separating plate with the first sidewall  108  and the second sidewall  109  respectively. The second sidewall  109  is region where rotating axis of the lower case body  101  and the lower case body  102  is located, and the first sidewall  108  is a sidewall on the case body directly facing the second sidewall  109 . The upper separating plate  103  and the lower separating plate  104  both are fixed on the case bodies through connection with the second sidewall  109  and the first sidewall  108 , facilitating removing or installing the separating plates. 
         [0054]    Each connecting belt set further includes a connecting section  107 , both the first belt set  105  and the second belt set  106  are connected or integrally formed with the connecting section  107 . The connecting belt  107  is used for fixing or compressing luggage. 
         [0055]    The connecting section  107  is used for tying the luggage into the suitcase. The luggage is pre-compressed into the storage chamber by the connecting section  107 , and then the luggage is further compressed by the separating plate, preventing small items from moving freely in the storage chamber, at the same time, the utilization ratio of the storage chamber can be improved since loose and soft luggage is compressed in volume so that the case body is capable of storing more luggage items. 
         [0056]    The connecting section  107  is in a shape of a triangle, the triangle has two endpoints located on the second sidewall  109  and another endpoint located on the first sidewall  108 , and the first belt set  105  and the second belt set  106  are fixed at the endpoints respectively. The connecting belt set is fixed with the case body at the three endpoints of the triangle.

         [0067]    The upper separating plate  103  and the lower separating plate  104  both can be disconnected from the first belt sets  105  and movable connected with the case bodies through the second belt sets  106 . When the upper separating plate  103  and the lower separating plate  104  are disconnected from the first belt sets  105 , the first side edges  111  of the upper separating plate  103  and the lower separating plate  104  can rotate, and during the rotating process, the first side edges  111  of the upper separating plate  103  and the lower separating plate  104  abut against each other such that the two separating plates can remain erected, with the second sidewall  109  located between the two separating plates. The storage chamber is completely exposed when the two separating plates are erected, making it convenient for the user to put luggage into the upper case body  101  and the lower case body  102 . By such a connection manner, the user can erect or lay down the separating plate  104  without changing his/her position with respect to the suitcase, facilitating operations. Meanwhile, the separating plates will not be flipped away from the storage chamber or be in contact with the ground. 
         [0068]    The upper separating plate  103  and the lower separating plate  104  are provided with a loop surface and a hook surface of the Velcro  113  respectively. When the first side edge  111  of the upper separating plate  103  and the first side edge  111  of the lower separating plate  104  abut against each other, the loop surface and the hook surface are in contact with each other. 
         [0069]    The upper separating plate  103  and the lower separating plate  104  are provided with corresponding Velcro  113 . The two separating plates, when abutting against each other to erect, are fixed through adhesion of the loop surface and the hook surface of the Velcro  113 , making it convenient to enable the two separating plates to maintain the erected state. 
         [0070]    In the present embodiment, the separating plate is in a quadrilateral shape, and four corners of the separating plate are provided with a notch  112  respectively, facilitating providing the separating plates into the upper case body  101  and the lower case body  102 . 
         [0071]    Because a joint of the sidewalls of the case bodies may be provided with chamfers or rounded angles and an internal space of the case body may be occupied when universal wheels are provided at the bottom of the case body, all of the four corners of the separating plate are provided with the notch  112 , making it easy to be adapted to spatial dimensions. 
         [0072]    The beneficial effects of the present application are as follows: a connecting belt set is provided inside the case body and the separating plate is limited by the connecting belt set, such that it facilitates adjusting a position of the separating plate, and it is not needed to remove the separating plate  104  when packaging the luggage or taking out the luggage, which is more convenient. The upper case body  101  and the lower case body  102  are opened and closed by rotating, and the upper separating plate  103  and the lower separating plate  104  are respectively connected in the upper case body  101  and the lower case body  102  by the connecting belt sets, making it convenient for the user to take out the luggage from or put the luggage into the storage chamber. Furthermore, two separating plates, when opened, can be enabled to abut against each other and erect, such that a user can more easily adjust the state of the separating plate. 
       Embodiment II 
       [0073]    Embodiment II of the present application provides a suitcase. Embodiment II differs from Embodiment 1 in that a first belt set and a second belt set in Embodiment II are connected with a separating plate by a button  114 .
