[0017] Figure 1 A schematic diagram of the structure of a smart suitcase provided by an embodiment of the present invention; Figure 2 A side view of a smart suitcase provided in an embodiment of the present invention.

[0018] See also Figure 1 and Figure 2 The smart suitcase provided by the embodiment of the present invention comprises an upper case 1 and a lower case 2. One side of the upper case 1 is connected to one side of the lower case 2. When buckled, the upper case 1 and the lower case 2 form a closed space to prevent the clothes in the smart suitcase from leaking out. A pull rod 3 is provided along the length direction of the back of the lower case 2. The pull rod 3 is a telescopic rod that can be pulled out or retracted in the back of the lower case 2. An upper handle 4 is provided on the top of the lower case 2. When the user needs to get on a car or walk up stairs, the user can hold the upper handle 4 and lift the smart suitcase to walk.

[0019] In order to improve the usability of the smart suitcase, the smart suitcase is further provided with a side handle 23, which is arranged at the middle of one side of the lower case 2. When the user pulls the side handle 23 to lay the smart suitcase flat, in order to avoid damage to the case, a plurality of pillars 29 are arranged on the side opposite to the side handle 23, so that the side is at a certain distance from the ground to avoid direct contact.

[0020] In order to reduce the burden on users during their journey, the smart suitcase provided in this embodiment can realize automatic travel without the need for users to pull the suitcase. To this end, in this embodiment, a controller 6 is provided in the lower box 2, and the controller 6 interacts with the user's smart terminal; the controller 6 can interact with the smart terminal via Bluetooth or wireless, or install an adapted APP on the smart terminal, bind a WeChat public account, WeChat applets and other control pages to achieve interaction, and the specific implementation method is not specifically limited in this embodiment. A distance sensor 7 is provided on the back of the lower box 2, and the distance sensor 7 is connected to the controller 6. The distance sensor 7 is used to detect the distance between the back of the lower box 2 and the user.

[0021] like Figure 4As shown, when the user wants the smart suitcase to move autonomously, the user sends an instruction to start autonomous movement to the controller 6 through the smart terminal, and the controller 6 controls the distance sensor 7 to perform distance detection to detect the distance between the back of the lower box 2 and the user. Because the user's waist will remain motionless relative to the smart suitcase when moving, therefore, under the premise of requiring the smart suitcase to move autonomously, it is necessary to place the smart terminal near the user's waist, such as in a clothes pocket or a trouser pocket. At this time, the smart terminal will send a signal to facilitate the distance sensor 7 to detect.

[0022] In the initial state, the smart suitcase is located on one side of the user's body, and the line between it and the user's body is approximately perpendicular to the forward direction. Therefore, the distance sensor 7 detects that the distance between it and the smart terminal is a vertical distance, and sends the distance value to the controller 6, which is processed by the data processing module in the controller 6. Figure 5 As shown, during data processing, it is proposed that in a right triangle, the distance value detected by the distance sensor 7 is a right-angled side L1. In order for the smart suitcase to move diagonally in front of the user, the distance that needs to be met is the hypotenuse L0, which is a set value and is pre-stored in the data processing module of the controller 6. According to the Pythagorean theorem, the distance length of the other right-angled side L2 can be determined, and the distance length is the distance that the smart suitcase needs to move forward so that the smart suitcase can move diagonally in front of the user. It can be seen that the smart suitcase provided in this embodiment can solve the problem in the prior art that the smart suitcase is located diagonally behind the user when automatically following, which is inconvenient for the user to take care of and easy to lose.

[0023] like Figure 3 As shown, four universal wheels 24 are evenly distributed at the bottom of the lower box body 2. The universal wheels 24 can rotate 360 ​​degrees along the bottom of the lower box body 2. The universal wheels 24 are connected to the controller 6 through the driving member 10. The driving member 10 can be a motor. The controller 6 generates a control instruction according to the determined driving distance value based on the distance value detected by the distance sensor 7 after a series of data processing, and sends it to the driving member 10 to control the driving member 10 to start, and the driving member 10 drives the universal wheels 24 to move the corresponding distance according to the determined distance value, so that the smart suitcase moves obliquely in front of the user.

[0024] When the user is moving, the driving member 10 drives the universal wheel 24 at a constant speed, so that the smart suitcase can always move diagonally in front of the user, thereby making the smart suitcase always within the user's sight, which is convenient for the user to take care of. When the user stops, the distance value detected by the distance sensor 7 gradually increases, such as Figure 6 As shown, when the current distance value L iWhen the upper limit of the stop threshold is exceeded, the controller 6 controls the driving member 10 to stop, so that the universal wheel 24 stops rotating, and then the smart suitcase stops moving. In this embodiment, the upper limit of the stop threshold can be set to 80 cm.

[0025] Since the smart suitcase provided in this embodiment can realize autonomous movement without the need for the user to pull it, although it frees the user's hands and reduces the burden of the user's travel, it is very easy for criminals to rob the smart suitcase because the user and the smart suitcase are in a separated state. Therefore, in order to allow the user to detect the robbery of criminals at the first time, in this embodiment, a speaker 8 is provided at the upper end of the back of the lower box body 2, and the speaker 8 is connected to the controller 6.

[0026] When the distance sensor 7 detects that the distance between the smart suitcase and the user exceeds the upper limit of the safety threshold, the upper limit can be set to 1m, and then an alarm instruction is generated through the controller 6 and sent to the speaker 8, which makes a sound to remind the user.

[0027] If the user hears the alarm but is unable to catch up with the criminals due to special circumstances, at this time, in order to accurately know the current location of the smart suitcase, in this embodiment, a GPS positioning device 27 is provided at the bottom of the lower box body 2, and the GPS positioning device 27 is connected to the controller 6. The GPS positioning device 27 is used to locate the smart suitcase and send it to the smart terminal through the controller 6.

[0028] The GPS positioning device 27 of the smart suitcase locates the current position in real time and sends the position information to the user's smart terminal through the controller 6 at any time. The user can track the smart suitcase according to the position displayed in the smart terminal.

[0029] Since the smart suitcase provided in this embodiment can move autonomously, the smart suitcase may collide with obstacles in front of it during the movement because it cannot predict the obstacles it will hit. In order to avoid this situation, in this embodiment, infrared sensors 28 are respectively provided on the two sides of the lower box body 2. The infrared sensors 28 are connected to the controller 6. The infrared sensors 28 are used to detect the distance between the corresponding sides of the lower box body 2 and the obstacles.

[0030] When a certain infrared sensor 28 detects that the distance between the corresponding side and the obstacle is close, the controller 6 controls the universal wheel 24 to turn left or right through the driving member 10, so that the smart suitcase avoids the obstacle and continues to move forward.

[0031] When the user places the smart suitcase on the right side of the body, the infrared sensor 28 on the side facing forward detects the distance to the obstacle; when the user places the smart suitcase on the left side of the body, the infrared sensor 28 on the other side detects the distance to the obstacle. When traveling in an environment with a lot of people, the outside of the suitcase will contact other people walking. In order to avoid collision with other people, an infrared sensor 28 can be set on the outside of the smart suitcase, that is, the outside of the upper box body 1. When the infrared sensor 28 detects that the distance between other people is close, the controller 6 drives the universal wheel 24 to rotate toward the user through the driving member 10, so that the smart suitcase moves a little distance toward the user to avoid other people walking.

[0032] In order to improve the user's control convenience of the smart suitcase, in this embodiment, an interactive interface 5 is provided on the top of the lower box body 2, and a USB interface 53 and a touch screen 52 for fingerprint recognition are provided on the interactive interface 5. The USB interface 53 is used to charge the user's smart terminal, and the touch screen 52 and the USB interface 53 are respectively connected to the controller 6.

[0033] An inner lock buckle 21 and an outer lock buckle 22 are provided at the closed opening where the upper box body 1 and the lower box body 2 are connected on the other side; the inner lock buckle 21 is connected to the controller 6, and the inner lock buckle 21 is the first lock; the telescopic part of the outer lock buckle 22 is placed in the inner lock buckle 21, and the outer lock buckle 22 is the second lock; the inner lock buckle 21 and the outer lock buckle 22 are double protection locks of the smart suitcase.

[0034] The storage module of the controller 6 pre-stores fingerprints that can control the opening and closing of the inner lock buckle 21. For example, the fingerprint of one specific finger can be used to open the inner lock buckle 21, and the fingerprints of two specific fingers can be used to close the inner lock buckle 21. Therefore, when the user needs to open or close the smart suitcase, the corresponding specific finger is placed on the touch screen 52. After the fingerprint is detected, it is sent to the controller 6. The controller 6 compares the fingerprint with the pre-stored fingerprint. If it matches the opening fingerprint, the inner lock buckle 21 is controlled to be opened; if it matches the closing fingerprint, the inner lock buckle 21 is controlled to be closed.

[0035] Since the inner lock 21 is an automatic lock, in order to prevent the upper case 1 and the lower case 2 from being separated immediately and causing the items in the case to scatter when the inner lock 21 is opened when the smart suitcase is in an upright state, in this embodiment, an outer lock 22 is provided as the final unlocking protection. The outer lock 22 and the inner lock 21 are mechanically connected, which can be a snap connection. When the inner lock 21 is opened, the user can manually pull the outer lock 22 out of the inner lock 21 to achieve full opening of the lock, thereby improving the user experience.

[0036] When the lock needs to be closed, the outer lock buckle 22 is first inserted into the inner lock buckle 21, and then two specific fingers are used to input fingerprints in the touch screen 52 to control the closing of the inner lock buckle 21 through the controller 6, and finally the lock is completely closed.

[0037] When using a smart suitcase to take an airplane, there are requirements for the weight of the suitcase. Overweight suitcases need to be checked in. In order to avoid wasting the user's time in determining the weight of the smart suitcase at the airport, in this embodiment, a weight sensor 26 is provided at the bottom of the lower case 2, and a display screen 51 is also provided on the interactive interface 5; the output end of the weight sensor 26 is connected to the input end of the controller 6, and the output end of the controller 6 is connected to the display screen 51; the weight sensor 26 is used to detect the weight of the smart suitcase, and the display screen 51 is used to display the weight value.

[0038] When users use smart suitcases to carry items, they can view the weight of the current items in real time, so that users can increase or decrease the weight of the items. If the size meets the requirements, it can meet the checked weight or boarding weight, which is convenient for users to use.

[0039] During a long journey, if items are left in a suitcase for a long time, they may become damp or have an odor. To avoid this, in this embodiment, a thermostat 9 is provided in the lower box 2. The thermostat 9 is connected to the controller 6. The thermostat 9 is used to maintain a constant temperature and dry the enclosed space formed by the upper box 1 and the lower box 2.

[0040] The opening and closing of the thermostat 9 can be controlled by the user's smart terminal. When the thermostat needs to be turned on, the smart terminal sends an opening signal to the controller 6, and then the controller 6 controls the thermostat 9 to turn on to dry the items in the suitcase to prevent the items from having odors due to moisture.

[0041] In this embodiment, the operation of the controller 6 and each sensor and the function of charging the smart terminal are powered by a battery 25, which is arranged at the bottom of the lower box 2, and is respectively connected to the controller 6, each sensor and the USB interface 53.

[0042] In order to store more electric energy in the battery 25 at all times to support the normal operation of the smart suitcase, a solar panel is provided on the outer surface of the upper case 1, and the solar panel is connected to the battery 25. The solar panel absorbs light energy and converts it into electric energy and stores it in the battery 25, so as to meet the demand of powering various components of the smart suitcase for a long time.

[0043] It can be seen from the above technical solution that the embodiment of the present invention provides a smart suitcase, including an upper case 1 and a lower case 2, wherein a controller 6 for interacting with a smart terminal is provided in the lower case 2, and a distance sensor 7 is provided on the back of the lower case 2, and the distance sensor 7 is used to detect the distance between the back of the lower case 2 and the user. The controller 6 determines the driving distance value according to the distance value detected by the distance sensor 7, and drives the universal wheel 24 to move the corresponding distance according to the distance value through the driving member 10, so that the smart suitcase moves obliquely in front of the user. When the distance sensor 7 detects that the distance between the smart suitcase and the user exceeds the upper limit of the safety threshold, the speaker 8 emits a sound to remind the user. In addition, a touch screen 52 for fingerprint recognition is provided on the top of the lower box body 2, and an inner lock buckle 21 and an outer lock buckle 22 are provided at the closed opening on the other side of the upper box body 1 and the lower box body 2; the inner lock buckle 21 is connected to the controller 6, and the telescopic part of the outer lock buckle 22 is placed in the inner lock buckle 21; the fingerprint status recognized by the touch screen 52 controls the opening and closing of the inner lock buckle 21 through the controller 6, and the inner lock buckle 21 and the outer lock buckle 22 are double protection locks of the smart suitcase, which improves the safety of use.
