[0002] Existing rideable suitcases usually include a suitcase body, a riding rear wheel at the bottom of the suitcase body, a riding front fork and a riding front wheel below the riding front fork. The riding front fork is retracted horizontally forward and backward relative to the suitcase body through a horizontally retractable telescopic sleeve and an electric push rod driving the telescopic sleeve to retract, so that the suitcase is in a riding state or a non-riding state.

[0003] The user controls the electric push rod to extend the riding front fork to put the suitcase in a riding state. In the riding state, the user rides on the suitcase body to drive the suitcase and controls the riding direction through the handlebar on the riding front fork.

[0004] However, the problem with the suitcase of this structural form is that when the user controls the electric push rod to retract the riding front fork to put the suitcase in a non-riding state, because the riding front wheel and the riding rear wheel on the suitcase body are fixed-direction directional wheels, they cannot automatically turn in the towing direction of the user like the universal wheels at the bottom of an ordinary suitcase. It is difficult for the user to turn when towing, which is not conducive to towing the suitcase in a non-riding state. Summary of the invention

DETAILED DESCRIPTION

[0054] Example 1: Figures 1 to 25 As shown, a foldable rideable suitcase comprises a case body 1, rollers at the bottom of the case body 1 for supporting the case body 1 to roll, a riding front fork 2 located in front of the case body 1, and a riding front wheel 3 below the riding front fork 2. A swing arm mechanism for rotating and folding toward the bottom of the case body 1 is installed on the case body 1, and the riding front fork 2 is installed on the swing arm mechanism. The riding front fork 2 is rotated and folded to the bottom of the case body 1 by the swing arm mechanism. The riding front fork 2 is provided with a rotating folding mechanism for folding the upper section of the riding front fork 2 protruding from the bottom of the case body 1 to the bottom of the case body 1 by rotating and folding.

[0055] The swing arm mechanism includes a swing arm 6 and a rotating shaft 7. The rotating shaft 7 is installed on the box body 1. The rear end of the swing arm 6 is rotatably connected to the box body 1 through the rotating shaft 7, and the front end of the swing arm 6 is connected to the riding front fork 2. The swing arm mechanism uses the motor 8 as power to perform electric rotation and folding. The rotating shaft 7 and the swing arm 6 are in a driving connection relationship. The motor 8 drives the swing arm 6 to rotate by driving the rotating shaft 7 to rotate. The rotating shaft 7 is connected to the swing arm 6 through a connecting block 16 that is inclined relative to the swing arm 6, driving the swing arm 6 to rotate. When the swing arm 6 rotates to open, the swing arm 6 is located above the rotating shaft 7.

[0056] In addition, when the swing arm mechanism is rotated to open, the swing arm 6 is parallel to the ground, and the riding front fork 2 is perpendicular to the ground. When the swing arm mechanism is rotated to fold, the swing arm 6 rotates 180 degrees to the bottom of the box body 1.

[0057] The rotating folding mechanism includes a folding hinge 9 and a folding lock mechanism 10. The folding hinge 9 is located at the rear side of the folding part of the riding front fork 2, and is used to allow the riding front fork 2 to be rotated and folded around the hinge axis of the folding hinge 9. The folding lock mechanism 10 is located at the front side of the folding part of the riding front fork 2, and is used to connect the upper and lower sides of the folding part, and unlock the connection relationship when folding is required. In this embodiment, the folding part of the riding front fork 2 is located at the connection point between the riding front fork 2 and the swing arm 6, and the two ends of the folding hinge 9 are respectively fixed to the upper section of the riding front fork 2 and the swing arm 6 by screws.

[0058] like Fig.14 As shown, the folding lock mechanism 10 includes a handle 10-1, a lock hook 10-2 and a lock slot 10-3. The handle 10-1 and the lock slot 10-3 are respectively located at the upper and lower sides of the folding part of the riding front fork 2. The end of the handle 10-1 is hingedly connected to the riding front fork 2, the lock slot 10-3 is fixedly connected to the riding front fork 2, the lock hook 10-2 is hingedly connected to the handle 10-1, and the hinge point of the lock hook 10-2 and the handle 10-1 is located between the handle 10-1 and the riding front fork 2. Above the hinge point of the riding front fork 2, when the folding lock mechanism 10 is in a locked state, the lock hook 10-2 hooks the notch of the lock slot 10-3, connecting the upper and lower sides of the folding part, and the handle 10-1 is attached to the riding front fork 2 under the action of the spring. When the handle 10-1 is pushed outward by overcoming the elastic force of the spring, the handle 10-1 drives the lock hook 10-2 to move downward, so that the lock hook 10-2 is disengaged from the notch of the lock slot 10-3, and the folding lock mechanism 10 is unlocked.

[0059] The rollers at the bottom of the box 1 include more than one universal wheel 5, which is used to facilitate the box 1 to turn in the direction of the user's pushing when the riding front fork 2 is retracted. The universal wheel 5 is retracted and extended by a retracting device. Figure 1 As shown, in this embodiment, specifically, the rollers at the bottom of the box body 1 include two directional riding rear wheels 4 and two universal wheels 5, the two riding rear wheels 4 are arranged in the same row in the left-right direction, and the two universal wheels 5 are arranged in the same row in the left-right direction, and when the riding front fork 2 is rotated and opened, the universal wheel 5 is located between the riding rear wheel 4 and the riding front wheel 3.

[0060] The retracting device of the universal wheel 5 is linked with the riding front fork 2 or the swing arm mechanism of the riding front fork 2, and is used to retract the universal wheel 5 through the retracting device when the riding front fork 2 is rotated to open, and to release the universal wheel 5 through the retracting device when the riding front fork 2 is rotated to retract.

[0061] The linkage device is a pull wire 11.

[0062] The pull wire 11 is connected to the swing arm 6 at the pull wire lead-out section on the side of the riding front fork 2, and the connection point between the pull wire 11 and the swing arm 6 is set above or below the rotating shaft 7. When the swing arm 6 is rotated to be retracted and rotated to be opened, the connection point between the pull wire 11 and the swing arm 6 produces a height difference change, and the swing arm 6 drives the pull wire 11 through the height difference change, and the pull wire lead-out section of the pull wire 11 on the side of the universal wheel 5 drives the retracting and extending device of the universal wheel 5 to retract and extend the universal wheel 5.

[0063] The retracting and extending device of the universal wheel 5 is a linear telescopic mechanism. The retracting and extending device lowers the universal wheel 5 under the action of the pull wire 11 , and resets and retracts the universal wheel 5 under the action of the reset spring 14 .

[0064] like Figures 15 to 18 As shown, the retracting and extending device of the universal wheel 5 specifically includes a retracting and extending guide tube 12, a guide rod 13 and a reset spring 14. The guide rod 13 is inserted into the retracting and extending guide tube 12 for extension and retraction. The reset spring 14 drives the guide rod 13 to reset and retract the universal wheel 5. The pull wire 11 is connected to the guide rod 13, driving the guide rod 13 to overcome the elastic force of the reset spring 14 to release the universal wheel 5.

[0065] The reset spring 14 and the guide rod 13 are arranged side by side in the tube cavity of the retractable guide tube 12. There is also a top plate 15 in the tube cavity of the retractable guide tube 12. The top plate 15 is located above the reset spring 14 and the guide rod 13. The guide rod 13 is fixed to the top plate 15, specifically by welding. The two ends of the reset spring 14 act on the top plate 15 and the bottom of the inner cavity of the retractable guide tube 12 respectively. The pull wire 11 passes through the reset spring 14 from bottom to top and is connected to the top plate 15.

[0066] The bottom of the retractable guide tube 12 has a universal wheel fixing seat 5-1, and the retractable device is fixed to the bottom of the box body 1 through the universal wheel fixing seat 5-1. The top of the retractable guide tube 12 is closed by an end cover 17 to prevent lubricating oil from spilling. Specifically, the end cover 17 is connected to the retractable guide tube 12 by screws.

[0067] A folding positioning mechanism is provided between the upper section of the riding front fork 2 and the swing arm 6 to position the folded state of the upper section of the riding front fork 2 after the riding front fork 2 is folded.

[0068] like Figures 9 to 13As shown, the folding positioning mechanism between the upper section of the riding front fork 2 and the swing arm 6 is specifically a positioning lock mechanism installed on the upper section of the riding front fork 2 and the swing arm 6, respectively. The positioning lock mechanism includes a lock head 18 and a lock head locking mechanism, which are installed on the upper section of the riding front fork 2 and the swing arm 6, respectively. The lock head locking mechanism is located inside the swing arm 6, and the swing arm 6 has a lock head insertion port 20. The lock head locking mechanism includes a lock tongue 19-1 and an unlocking rod 19-2. The lock tongue 19-1 is pushed out by a spring to lock the lock head 18 inserted into the swing arm 6. One end of the unlocking rod 19-2 extends out of the swing arm 6, and the other end forms an oblique wedge mechanism with the lock tongue 19-1. The lock tongue 19-1 is retracted by pressing the unlocking rod 19-2, and the lock tongue 19-1 is released from locking the lock head 18. The lock head locking mechanism is installed inside the swing arm 6 through the cover plate 19-3 on the swing arm 6.

[0069] The riding front fork 2 is the steering mechanism of the suitcase when riding. The upper part of the riding front fork 2 has two foldable handlebars 21. The handlebars 21 on the left and right sides are rotatably and foldably connected to the riding front fork 2 through a rotating joint. The rotating axis of the rotating joint is a handle pin 22. A locking sleeve 23 is sleeved on the handlebar 21. The locking sleeves 23 on the left and right sides are movably sleeved on the rotating joint of the handlebar 21 to lock the handlebar 21 so that the handlebars 21 on the left and right sides cannot rotate around the rotating joint. The handlebar 21 is unlocked by moving the locking sleeve 23 away from the rotating joint. The head of the locking sleeve 23 has a magnet 24, and the fixed side of the rotating joint also has a magnet 24 or ferromagnetic material, and the locking sleeve 23 is positioned by magnetism.

[0070] More specifically in this embodiment:

[0071] The motor 8 outputs driving force through the gear box 8 - 1 .

[0072] The rear end of the swing arm 6 is a reinforcement block 25 for stabilizing the swing arm.

[0073] The cable 11 is guided by a cable sleeve 11-1 sleeved on the outside thereof. One end of the cable sleeve 11-1 is fixed on the universal wheel fixing seat 5-1, and the other end of the cable sleeve 11-1 is fixed on the box body 1 through a cable sleeve fixing plate 11-2. The cable sleeve fixing plate 11-2 is located below the rotating shaft 7. A bearing is installed in the cable sleeve fixing plate 11-2, so that the cable sleeve 11-1 can rotate within a certain degree when subjected to force. The end of the cable sleeve 11-1 is a cable outlet 27. The cable lead-out section led out from the end of the cable sleeve 11-1 on one side of the riding front fork 2 is fixed to the reinforcing block 25 through the cable fixing piece 11-3 at the end of the cable, so as to realize the connection between the cable 11 and the swing arm 6.

[0074] In this embodiment, the connection point of the pull wire 11 and the swing arm 6 is located below the rotating shaft 7, and the pull wire outlet 27 on the swing arm 6 side of the pull wire 11 is located below the rotating shaft 7. When the swing arm 6 is rotated and retracted, the connection point of the pull wire 11 and the swing arm 6 produces a height difference change, moving from below the rotating shaft 7 to above the rotating shaft 7, tightening the pull wire 11, and the pull wire 11 links the retracting device of the universal wheel 5 to release the universal wheel 5.

[0075] The upper section of the riding front fork 2 is rotated and folded to be aligned with the swing arm 6 up and down.

[0076] The riding front wheel 3 is a power source during riding and is driven by a hub motor in the riding front wheel 3 .

[0077] The swing arm 6 is a flat square tube and can be used as a pedal for the rider to place his feet when riding.

[0078] The riding rear wheel 4 is fixed on the box body 1 through the riding rear wheel fixing seat 4-1. The universal wheel fixing seat 5-1 plays the role of the retracting and releasing device supporting the universal wheel 5.

[0079] The rotating shaft 7 is installed on the housing 1 through a fixed bearing seat 7-1 fixed on the housing 1, and a bearing is installed in the fixed bearing seat 7-1.

[0080] The upper section of the riding front fork 2 is a telescopic two-section sleeve structure, which is locked and unlocked by a hoop 26. The handlebars 21 on the left and right sides are installed on the extended handlebar tube, and the handlebar tube can be unlocked by loosening the hoop 26 to adjust the extended length of the handlebar tube.

[0081] The top of the box body 1 can be used as a seat cushion for a user to ride on the box body 1.

[0082] The bottom of the box body 1 is provided with a folding receiving groove, and the riding front fork 2, the riding front wheel 3 on the riding front fork 2 and the swing arm 6 are rotated and folded into the folding receiving groove of the box body 1.

[0083] The working process and principle of this embodiment are as follows:

[0084] 1. Change from riding state to non-riding state:

[0085] 1.1. After loosening the clamp 26, retract the handlebar to the lowest height and then tighten the clamp 26.

[0086] 1.2, as follows Figure 1-5 As shown, the folding handlebar 21:

[0087] By overcoming the magnetic positioning and pushing the locking sleeves 23 on the left and right sides outward, the locking sleeves 23 are separated from the rotating joints of the handlebars 21, the handlebars 21 on the left and right sides are unlocked, and the handlebars 21 on the left and right sides are rotated inwards by 90 degrees to complete the folding of the handlebars 21. Similarly, the reverse operation is the unfolding operation of the handlebars 21.

[0088] 1.3. Folding the upper section of the riding front fork 2: Overcoming the elastic force of the spring, the handle 10-1 is pushed outward, and the handle 10-1 drives the lock hook 10-2 to move downward through the hinge shaft, so that the lock hook 10-2 is disengaged from the notch of the lock slot member 10-3. At this time, the riding front fork 2 is in a foldable state. The upper section of the riding front fork 2 is folded in one direction through the folding hinge 9 to be parallel to the swing arm 6.

[0089] When the upper section of the riding front fork 2 is folded to be parallel to the swing arm 6, the lock 18 on the riding front fork 2 is inserted into the swing arm 6 through the lock insertion port 20 on the swing arm 6, and the extended lock tongue 19-1 of the lock locking mechanism locks the lock 18, connecting the upper section of the riding front fork 2 and the swing arm 6 together, thereby achieving the folding positioning between the upper section of the riding front fork 2 and the swing arm 6.

[0090] 1.4. Rotate and fold the front riding wheel 3 into the box:

[0091] With the riding rear wheel 4 as a fulcrum, the riding front wheel 3 is tilted, and then the motor 8 is started, and the motor 8 is reversed. The gear box 8-1 connected to the motor 8 drives the rotating shaft 7 fixed to the gear box 8-1 to rotate. Because the connecting block 16, the rotating shaft 7 and the swing arm 6 are integrated, and the motor 8 and the gear box 8-1 are fixed inside the box body 1, when the rotating shaft 7 rotates, the swing arm 6 is driven to rotate at the same time, and the motor 8 drives the swing arm 6 to rotate 180 degrees in the opposite direction, and the riding front fork 2 is retracted to the bottom of the box body 1.

[0092] When the motor 8 drives the swing arm 6 to rotate and retract the riding front fork 2, the connection point between the cable 11 and the swing arm 6 moves from below the rotating shaft 7 to above the rotating shaft 7, the cable 11 is tightened, and the power is transmitted to the retracting and releasing device of the universal wheel 5.
