Description

Intelligent luggage case

Technical Field

The invention relates to a luggage case, in particular to an intelligent luggage case.

Background

The suitcase includes box, pull rod and gyro wheel. When a user drags or pushes the suitcase to move for a long time through the pull rod, a great deal of physical strength is required to be consumed, so that the physical fatigue of the user is easily caused, and the mood of the user during use is influenced.

The electric luggage case comprises a case body, rollers, a battery, a motor for driving the rollers to rotate, a motor control device connected with a motor signal and a control handle connected with the motor control device signal. Compared with the common luggage case, the electric luggage case has the advantages that a user can ride on the case body, the steering of the electric luggage case is realized by rotating the control handles through both hands, and the forward movement, the backward movement and the acceleration and deceleration of the electric luggage case are realized by pressing corresponding keys. The electric luggage case needs two hands to operate and can not liberate the hands of a user; when a user straddles the box body, if the box body is vertically placed on the ground, the problem of high gravity center position and poor running stability exists; if the box body is placed on the ground, although the gravity center position is reduced, the running stability is improved, the riding posture of a user is influenced necessarily when the gravity center is reduced, and the legs are bent excessively, so that the riding comfort is poor; and the height distance between the box body and the user is increased when the box body is placed on the ground, so that the electric luggage case is inconvenient for the user to move.

The terms "front," "rear," "left," "right," "upper," "lower," and the like refer to an orientation or positional relationship based on that shown in the drawings, for convenience of description and simplicity of description, and do not necessarily indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the invention. The terms "first" and "second" are used merely to simplify the description and distinguish between similar objects, and are not to be construed as precedence relationships between a particular order.

Referring to fig. 1 and 5, the intelligent trunk of the present embodiment includes a case 1, wheels 2 mounted at the bottom of the case 1, and a pull rod 3 mounted on the case 1 for dragging or pushing the intelligent trunk to move. The case 1 includes a first split 11 and a second split 12 located below the first split 11. The tie rod 3 is mounted on the first body 11 and the wheel 2 is mounted on the second body 12. The first split 11 has a first accommodation space to facilitate accommodation of the article. The second body 12 has a second housing space in which the power supply 123 and the self-balancing control system 125 are installed. Of course, in other embodiments, the power supply and the self-balancing control system may also be installed in the first accommodating space. The bottom wall of the first sub-body 11 is opposite to the top wall of the second sub-body 12 and is located above the top wall of the second sub-body 12. The first sub-body 11 is rotatably connected to the second sub-body 12 by means of a vertically arranged steering control mechanism 4.

The intelligent trunk has two state modes, a riding state and a non-riding state. When the intelligent trunk is in a non-riding state, the front wall of the first split body 11 is perpendicular to the advancing direction of the wheels 2 (as shown in fig. 2), and the intelligent trunk can be used as a common trunk at this time, i.e. a user can drag or push the intelligent trunk to move through the pull rod 3. When the intelligent trunk is in a riding state, the front wall of the first split 11 is parallel to the advancing direction of the wheel 2 (as shown in fig. 3 and 4), and the user can ride on the first split 11 perpendicular to the second split 12, and can tread on the foot rest parts 128 at two ends of the top wall of the second split 12. The riding comfort is improved while the running stability is improved. The first split 11 can rotate relative to the second split 12 around the steering control mechanism 4, so that the intelligent trunk can be switched between a non-riding state and a riding state. It should be noted that: in this embodiment, the first split 11 rotates relative to the second split 12, so that not only can the intelligent trunk be converted between the non-riding state and the riding state, but also the intelligent trunk can be turned through twisting of the body of the user (at this time, the turning angle of the first split 11 relative to the second split 12 is smaller).

In this embodiment, the number of wheels 2 is two, and the two wheels 2 are power wheels controlled to rotate by a motor. The motor is a hub motor which is mounted inside the wheel 2. Of course, in other embodiments, the power wheel can also be driven to rotate by a gear motor, and the gear motor is installed outside the wheel. The two power wheels are respectively arranged on the left side and the right side of the second split body 12 through wheel shafts. Grooves for accommodating the power wheels are concavely formed in the two sides of the bottom of the second split body 12, so that the side edges of the two power wheels are flush with the left and right side walls of the box body 1, and the attractiveness of the intelligent trunk is improved. The in-wheel motor signal for each power wheel is connected to a self-balancing control system 125. The steering control mechanism 4 is also signally connected to a self-balancing control system 125. The power source 123 may provide power to the two powered wheels, the self-balancing control system 125, and the steering control mechanism 4. The self-balancing control system 125 includes a gyroscope to detect the operational pose of the intelligent trunk. In the moving process of the intelligent trunk in the riding state, the self-balancing control system 125 can calculate proper instructions according to the running gesture information of the trunk body 1 detected by the gyroscope after analysis and processing, and transmit the instructions to the two hub motors, so as to control the two power wheels to rotate to realize the balance state of the intelligent trunk moving back and forth. The user twists the first split 11 through the body, and the steering control mechanism 4 is used for detecting the angle rotation information of the first split 11 relative to the second split 12, transmitting the angle rotation information to the self-balancing control system 125, analyzing and processing the angle rotation information, calculating a proper instruction, transmitting the instruction to the two hub motors, and enabling the two power wheels to form differential rotation to realize the steering of the intelligent trunk.

Of course, in other embodiments, the intelligent luggage case can also be provided with only one wheel hub motor wheel, and the intelligent luggage case can move back and forth and steer in a similar operation mode of a single wheel balance car.

Of course, in other embodiments, the technical structure of the case 1 may be applied to an electric luggage case without a self-balancing function. The technical structure of the box body 1 mainly refers to a box body which is provided with a first split body 11 and a second split body 12 which can rotate relatively, and the first split body 11 and the second split body 12 are vertically arranged. The first split 11 and the second split 12 can be connected through a limiting rotating shaft. The user realizes forward and backward movement and steering by operating the operation controller. Of course, the technical structure of the case 1 can also be applied to a general trunk. The user can ride on the first split 11 and support the first split on the ground through two feet, and the two feet and the ground form friction to push the common trunk to move. It should be noted that: when the technical structure of the case 1 is applied to an electric luggage case or a general luggage case having no self-balancing function, the number of the wheels 2 mounted on the second body 12 is not limited, and the number of the wheels 2 may be one or more.

Compared with the prior art, the technical structure of the case 1 of the present invention is a case 1 with a unitary structure, when the front wall of the case 1 (the front wall of the first and second split bodies 11 and 12) is perpendicular to the advancing direction of the wheel 2, the user can rotate the first split body 11 relative to the second split body 12, so that the front wall of the first split body 11 is parallel to the advancing direction of the wheel 2. The intelligent suitcase is beneficial to improving the running stability of the intelligent suitcase when a user straddles the suitcase body 1. The user can also effect movement of the intelligent trunk through the pull rod 3 when the intelligent trunk is switched to the non-riding state. The invention provides a fresh luggage case using structure. In addition, compared with the embodiment of the prior art that the user straddles the box body placed on the ground, the user can straddle the box body placed on the ground, so that riding comfort is improved, sight line height is increased, and bending degree of legs is reduced; it is also convenient for the user to pull the pull rod 3 mounted on the case 1.

In this embodiment, as shown in fig. 4, the front part of the first split body 11 is opened with an opening for taking out an article, and the opening is fitted with a box cover 14 through a zipper 13. The cover 14 is hinged to the front wall of the first segment 11 by a hinge. After the cover 14 is opened, the opening of the cover faces upward of the case 1. A connecting net bag (not shown) is arranged between the box cover 14 and the opening, and can limit the rotation angle of the box cover 14 relative to the opening of the opening and can prevent the articles placed in the first accommodating space from sliding outside the box body 1. The pull rod 3 is telescopically mounted on the rear wall of the first split 11.

Referring to fig. 1 and 5, the second sub-body 12 includes a housing body 121 that is opened upward, and a closing lid 122 that covers the housing body 121. The closure 122 is a top wall of the second body 12. The second body 12 after the cover is closed forms a second accommodation space. The second accommodating space is provided with an accommodating groove 124 for installing the power supply 123, and the power supply 123 is fixedly installed in the accommodating groove 124. The self-balancing control system 125 is also fixedly installed in the second accommodating space by screws. The rear wall of the second body 12 is provided with a charging socket 126 for charging the power supply 123 and a switch button 127 for starting the intelligent balance car. Of course, in other embodiments, the switch button 127 may also be mounted on the first split 11 of the case 1.

The closure body 122 has a pedal portion 128 (shown in fig. 4) at both ends. Both foot steps 128 are provided with anti-slip patterns (not shown) for reducing the sliding movement of the user's feet relative to the closure body 122. The first split 11 covers the foot pedal 128 when the intelligent luggage case is in the non-riding state. When the intelligent trunk is in a riding state, a user can ride on the first split body 11 perpendicular to the second split body 12, and can tread on the pedal parts 128 at two ends of the closed cover 122. What should be stated here is: the riding state can be that the user sits and rides on the first split body 11, the two legs of the user are separately positioned at two sides of the first split body 11, and the user treads or does not tread on the pedal part 128 of the second split body 12; the riding state may be that the user is riding on the second split body 12 while standing with his/her legs on both sides of the first split body 11, and the user steps on the pedal portion 128 of the second split body 12. When a user sits on the first split body 11 in a riding state, the trunk part of the user twists the body to drive the buttocks to twist the first split body 11 to rotate relative to the second split body 12, so that the steering of the intelligent trunk is realized; when the user is in a riding state to stand and ride on the second split body 12, the user steps on the two pedal parts 128 correspondingly by two feet, and the legs of the user twisting the body clamp the first split body 11 to rotate relative to the second split body 12 through the two legs, so that the steering of the intelligent trunk is realized.

Referring to fig. 5 to 7, the closed cover 122 is provided with a through hole for receiving the steering control mechanism 4, and the steering control mechanism 4 is vertically disposed. The steering control mechanism 4 is mounted in the second housing space and extends in the direction of the first split body 11. The steering control mechanism 4 includes a stator 5 fixed to the second split member 12, a steering control torsion bar 6 mounted to the stator 5 so as to be rotatable with respect to the stator 5, and a state switching rotator 7 fixed to the first split member 11. The stator 5 is provided with a sensor 55 for detecting the rotation angle of the steering control torsion bar 6 relative to the stator 5, the sensor 55 is in signal connection with a self-balancing control system 125, and the self-balancing control system 125 drives two power wheels to rotate in a differential mode after calculation according to the angle rotation information, so that the intelligent suitcase is steered. The upper end of the steering control torsion bar 6 of the steering control mechanism 4 penetrates through a through hole formed in the closure cover 122, and is axially sleeved on the state transition rotary member 7. The state switching rotator 7 is rotatably connected to the steering control torsion bar 6, and the rotation angle between the state switching rotator 7 and the steering control torsion bar 6 is 90 degrees. The first split 11 rotates relative to the second split 12 around the axis of the state transition rotary member 7 and the steering control torsion bar 6, so that the intelligent trunk can be transitioned between the riding state and the non-riding state. The limiting piece is arranged between the state conversion rotating piece 7 and the steering control torsion rod 6, and can limit the rotating angle of the state conversion rotating piece 7 relative to the steering control torsion rod 6, so that the intelligent trunk keeps a riding state or a non-riding state, and meanwhile, the state conversion rotating piece 7 and the steering control torsion rod 6 can also keep a relatively fixed state. The user can adjust the position of locating part for the conversion of intelligent suitcase under two kinds of states. In addition, when the intelligent trunk is in a riding state, a user twists the body to enable the first split body 11 to rotate relative to the second split body 12 (the relative rotation angle is smaller at the moment), the state conversion rotating piece 7 fixedly connected to the first split body 11 drives the steering control torsion rod 6 to rotate, the steering control torsion rod 6 rotates relative to the stator 5 fixedly connected to the second split body 12, and the intelligent trunk is steered through angle rotation information detected by the sensor 55 and control of the self-balancing control system 125. The stator 5 is further provided with a steering reset member 54, and after the torsion of the user twisting the first split body by the body is eliminated, the steering reset member 54 resets the first split body 11 to an initial position in a riding state relative to the second split body 12. Of course, in other embodiments, the stator 5 may be configured to return the first split body 11 to the initial position in the riding state with respect to the second split body 12 by merely twisting the body in the opposite direction by the user without installing the steering return member 54.

In this embodiment, one end of the state transition rotation member 7 is fixedly connected to the first split body 11. The bottom wall of the first split body 11 is concavely provided with a mounting groove 15 of the mounting state switching rotation member 7. The mounting groove 15 is provided with respect to a through hole formed in the second casing 12 closing cover 122. The top end of the state transition rotation member 7 is welded with a reinforcing fixing plate 71, and the size of the reinforcing fixing plate 71 is larger than the cross-sectional size of the state transition rotation member 7. The reinforcing fixing plate 71 is fixedly attached to the bottom wall of the first split body 11 concavely provided with the mounting groove 15 by screws. The mounting fastness of the state transition rotation member 7 with respect to the first split body 11 is further improved. The other end of the state conversion rotating piece 7 is sleeved on the steering control torsion rod 6 and limits the relative rotation angle through a limiting piece.

The limiting piece is fixedly connected to the state transition rotating piece 7. The steering control torsion bar 6 is fitted around the outer periphery of the state switching rotator 7. The outer circumferential surface of the steering control torsion bar 6 is provided with a limit chute 61 for limiting the rotation angle of the state transition rotation member 7. The limiting piece can rotate relative to the steering control torsion bar 6 along with the state conversion rotating piece 7 and can slide in the limiting sliding groove 61; the limiter can also move up and down axially with respect to the steering control torsion bar 6 following the state transition rotator 7. The limiting chute 61 comprises a first angle limiting part and a second angle limiting part which are respectively positioned at two end parts of the limiting chute 61. When the limiting piece rotates along with the state conversion rotating piece 7 and is limited at the first angle limiting part, the intelligent trunk is in a non-riding state; when the limiting piece rotates in the reverse direction along with the state conversion rotating piece 7 and is limited at the second angle limiting part, the intelligent trunk is in a riding state.

Referring to fig. 6 and 7, in the present embodiment, the state transition rotary member 7 is a hollow rod. The limiting member is a pin 72, and the pin 72 penetrates through the state transition rotating member 7 and both ends of the pin protrude from the outer peripheral surface of the state transition rotating member 7. The outer peripheral surface of the steering control torsion bar 6 is provided with two limit sliding grooves 61, and the two limit sliding grooves 61 are oppositely arranged and respectively correspond to two ends of the pin shaft 72. The protruding portions at both ends of the pin 72 are slidably connected to the two limit grooves 61, respectively. When the two protruding portions slide relative to the two limit sliding grooves 61, the sliding directions of the two protruding portions are consistent, and the functions are consistent. The two limit grooves 61 can increase the angular limit stability of the state transition rotation member 7 relative to the steering control torsion bar 6 compared to one limit groove 61. An elastic member 8 in a compressed state is provided between the state switching rotation member 7 and the steering control torsion bar 6, and the elastic member 8 is accommodated in a hollow portion of the state switching rotation member 7. The elastic member 8 is a spring or rubber. One end of the elastic member 8 is held against the pin 72, and the other end of the elastic member 8 is held against the stopper 62 provided inside the steering control torsion bar 6.

In this embodiment, the first angle limiting portion is a first limiting groove 63 disposed at one end of the limiting chute 61 and extending upward. The second angle limiting part comprises a second limiting groove 64 which is arranged at the other end of the limiting chute 61 and extends downwards, and a third limiting groove 65 which is arranged at the other end of the limiting chute 61 and extends upwards. The third limiting groove 65 is disposed above the second limiting groove 64. The intelligent luggage case supports the acting force of the pin shaft 72 upwards through the elastic piece 8, so that the user sits on the first split body 11 to enable the gravity of the first split body 11 to downwards displace, and the acting force of the user pressing the first split body 11 downwards through the hand is matched, so that the pin shaft 72 is limited in the first limiting groove 63, the second limiting groove 64 or the third limiting groove 65. Wherein, when the pin shaft 72 is limited to the first limiting groove 63, the intelligent trunk is in a non-riding state; when the pin shaft 72 is limited to the second limiting groove 64, the intelligent trunk is in a riding state that a user sits and straddles on the first split body 11; when the pin shaft 72 is limited to the third limiting groove 65, the intelligent trunk is in a riding state that the user straddles the second split body 12 in a standing manner. It should be noted that: the riding state that the user sits and straddles on the first split 11 requires the user to sit on the first split 11, when the buttocks of the user are separated from the first split 11, the acting force of limiting the pin shaft 72 on the second limiting groove 64 is lost, at this time, the pin shaft 72 is limited in the third limiting groove 65 due to the rebound force of the elastic piece, and the riding state that the intelligent trunk sits and straddles on the first split 11 by the user is converted into the riding state that the user stands and straddles on the second split 12 by the user. When the user sits on the first split 11 again, the pin shaft 72 can be limited in the second limiting groove 64 again, and the corresponding riding state of the intelligent trunk where the user sits on the second split 12 is converted into the riding state where the user sits on the first split 11. The conversion is convenient and quick, and the riding pleasure is also increased.

Of course, when the intelligent trunk is converted from the non-riding state to the riding state, or when the intelligent trunk is converted from the riding state to the non-riding state, the conversion operation can be realized only after the user needs to separate from the intelligent trunk, so that the riding state defaults to the riding state that the user stands on the second split body 12. When the user switches between the two states, the intelligent trunk is in the power supply 123 off state, and only when the user sits on the first split 11 or stands on the second split 12, the intelligent trunk is opened through the switch key 127.

In this embodiment, the principle of the mutual conversion between the riding state and the non-riding state of the intelligent trunk is as follows:

1. The intelligent luggage case is converted from a non-riding state to a riding state: the intelligent trunk can be understood as a general trunk in a non-riding state (the front wall of the first split 11 is perpendicular to the advancing direction of the wheels 2). Firstly, a user presses the first split body 11 downwards through hand force, and the pin shaft 72 moves downwards axially relative to the steering control torsion rod 6 along with the state conversion rotating piece 7, so that the pin shaft 72 is separated from the first limit groove 63; secondly, the user rotates the first split 11 relative to the second split 12, and the pin shaft 72 rotates relative to the steering control torsion bar 6 along with the state transition rotating piece 7 and slides to a position corresponding to the second limit groove 64 along the limit sliding groove 61; then, the user stops the hand force to press the first split body 11 downwards, at this time, the elastic piece upwards supports the force of the pin shaft 72, the pin shaft 72 moves upwards axially along with the state conversion rotating piece 7 relative to the steering control torsion bar 6, so that the pin shaft 72 is limited in the third limiting groove 65, and at this time, the intelligent trunk is in a riding state that the user straddles the second split body 12 in a standing manner (the front wall of the first split body 11 is parallel to the advancing direction of the wheel 2); of course, when the user sits on the first split body 11, the body generates downward gravity, so that the pin shaft 72 is limited to the second limiting groove 64 by the third limiting groove 65, and the intelligent trunk is in a riding state that the user sits on the first split body 11. The user can move and steer the intelligent trunk forward or backward by tilting the body forward or backward and by twisting the body to turn the first split 11 in conjunction with the self-balancing control system 125.

2. The intelligent luggage case is converted into a non-riding state from the riding state: in the riding state (the front wall of the first split 11 is parallel to the advancing direction of the wheel 2), the pin 72 is limited in the third limiting groove 65 due to the fact that the user is separated from the intelligent trunk. Firstly, a user presses the first split body 11 downwards through hand force, and the pin shaft 72 moves downwards axially relative to the steering control torsion bar 6 along with the state conversion rotating piece 7, so that the pin shaft 72 is separated from the third limit groove 65; secondly, the user reversely rotates the first split body 11 relative to the second split body 12, the pin shaft 72 rotates relative to the steering control torsion bar 6 along with the state conversion rotating piece 7, and slides to a position corresponding to the first limit groove 63 along the limit sliding groove 61; then, the user stops the hand force to press the first split body 11 downwards, and at this time, the pin shaft 72 moves axially upwards relative to the steering control torsion bar 6 along with the state conversion rotating member 7 by the force of the elastic member to push up the pin shaft 72, so that the pin shaft 72 is limited in the first limiting groove 63, and at this time, the intelligent trunk is in a non-riding state (the front wall of the first split body 11 is perpendicular to the advancing direction of the wheel 2). The user can drag or push the intelligent luggage case to move through the pull rod 3.

In this embodiment, a gap is left between the first split 11 and the second split 12, so that when the user presses the first split 11 downward by hand force, the gap length between the first split 11 and the second split 12 is greater than the spacing height between the first spacing groove 63 and the second spacing groove 64.

Of course, in other embodiments, the first and second angle limiting portions at two ends of the limiting chute 61 may also be a clamping block or a positioning pin for limiting the displacement of the limiting member.

Referring to fig. 7, the stator 5 includes a housing 51, a fixed seat body 52 mounted on an upper portion of the housing 51, a rotating seat body 53 mounted on a lower portion of the housing 51 and fixedly coupled to the steering control torsion bar 6, and a steering restoring member 54 mounted between the fixed seat body 52 and the rotating seat body 53. The housing 51 is fixedly connected to the bottom wall of the second split body 12 by screws. The upper end surface of the housing 51 is provided with a through hole through which the steering control torsion bar 6 is received. The lower end of the steering control torsion bar 6 extends through a through hole formed in the housing 51, extends downward to the lower portion of the housing 51, and is fixedly connected to the rotary housing 53, so that the rotary housing 53 is rotatably connected to the housing 51 by rotation of the state switching rotary member 7. The steering reset piece 54 is sleeved on the periphery of the steering control torsion bar 6 and is positioned between the fixed seat body 52 and the rotating seat body 53. The upper end of the steering reset piece 54 is connected with a fixed seat body 52, and the fixed seat body 52 is fixedly connected to the upper part of the shell 51; the lower end of the steering reset piece 54 is connected with a rotating seat body 53, and the rotating seat body 53 is rotatably connected with the lower part of the shell 51 through a bearing.

Under riding state, the intelligent trunk can make the state conversion rotating piece 7 drive the steering control torsion rod 6 to rotate relative to the stator 5 by the user sitting on the first split 11 to twist the body or standing on the second split 12 to twist the first split 11 through legs of the body. A sensor 55 for detecting rotation of the steering control torsion bar 6 relative to the stator 5 is mounted on the inner wall of the housing 51. The sensor 55 is an angular displacement sensor, a photoelectric sensor or a hall sensor. In this embodiment, the sensor 55 is a hall sensor. The rotary base 53 is provided with a magnet to be detected by a hall sensor. The hall sensor detects the amount of change in the magnetic field of the magnet when the rotating base 53 rotates together. The hall sensor is signally connected to the self-balancing control system 125. The self-balancing control system 125 calculates according to the angle rotation information to drive the two power wheels to rotate in a differential mode, and therefore intelligent suitcase steering is achieved. After the intelligent trunk is turned, the intelligent trunk can be reset to the initial position in the riding state through the turning reset piece 54.
