Description

Technical Field

[0001] The utility model belongs to the luggage box technology, and in particular relates to an electric luggage box with steering and push-pull functions integrated into the same handle. Background Art

[0002] Electric luggage is an improvement on trolley cases. Trolley cases are equipped with a push-pull rod on the case body for pushing and pulling the suitcase. Electric luggage is based on trolley cases with an electric drive function. During the electric drive process, the steering of the luggage is achieved by turning the steering rod.

[0003] In order to retain the push-pull function, the existing electric suitcase is usually equipped with both a push-pull rod and a steering rod (handle rod), which results in a complex structure, high manufacturing cost, and heavy weight. Under the premise of setting the outer contour, the capacity of the suitcase is reduced.

[0004] In addition, the existing electric suitcases have a push-pull rod and / or a steering rod disposed inside the suitcase, and a power supply compartment is disposed on the suitcase to install a power supply for powering the electric suitcase. This not only occupies the storage space of the suitcase and reduces the capacity of the suitcase, but also causes the storage space of the suitcase to be irregular, thereby reducing the capacity of the suitcase. Utility Model Content

[0005] The technical problem to be solved and the technical task proposed by the utility model are to overcome at least one of the above-mentioned defects caused by the fact that the existing electric suitcases are equipped with both a push-pull rod and a steering rod on the box body, and to provide an electric suitcase with steering and push-pull functions integrated in the same handle.

[0006] To achieve the above-mentioned purpose, the electric luggage case with steering and push-pull functions integrated into the same handle of the utility model comprises:

[0007] Box;

[0008] A driving wheel, which is mounted on the box and drives the box to move by means of electricity provided by a power source;

[0009] A handle, which is mounted on the box body and rotates around its own axis relative to the box body;

[0010] Training wheels, which are steered by the handlebars;

[0011] The locking structure is used to lock the handle bar to prevent the handle bar from rotating relative to the box body or to unlock the handle bar to allow the handle bar to rotate relative to the box body.

[0012] The electric suitcase, when the handlebar is locked by the locking structure to prevent the handlebar from rotating relative to the suitcase body, is placed in a push-pull mode, the suitcase is tilted, the driving wheels leave the ground to reduce resistance, and the handlebar is used as a push-pull rod to push and pull the suitcase to move. Since the handlebar is locked and cannot rotate relative to the suitcase body, the suitcase body is prevented from flipping relative to the handlebar when the tilted suitcase is pushed or pulled by the handlebar.

[0013] The electric luggage case is placed in an electric mode when the handle is unlocked to allow the handle to rotate relative to the case body, and the driving wheel drives the luggage case to move, and the handle is turned to turn the electric luggage case. Moreover, the case body is suitable for riding.

[0014] The electric luggage case has a handle that is locked and unlocked by a locking mechanism, and the steering and push-pull functions of the electric luggage case are integrated into the same handle. Compared with the electric luggage case in the prior art that is equipped with both a push-pull rod and a steering rod on the case body, the structure is simplified, the manufacturing cost is reduced, and the weight is small, making it easy to carry. Under the premise of setting the outer contour, it is conducive to increasing the storage space of the case body.

[0015] In one embodiment, there is one driving wheel and it is arranged at the left and right center position of the bottom of the box body. One driving wheel is conducive to reducing the manufacturing cost and weight of the product.

Accordingly, the handlebar can be flexibly rotated to achieve steering. In particular, the handlebar is placed outside the box body and does not occupy the accommodation space inside the box body, so that the accommodation space inside the box body is basically consistent with the shape and contour of the box body, maintaining regularity and improving the accommodation capacity.

[0019] Preferably, the swivel seat is cylindrical, and bearings are arranged at both ends of the swivel seat for the handlebar to be rotatably assembled on the swivel seat. Accordingly, the ability of the handlebar to withstand external forces is improved. For example, when a person sits on the box body, a large load will be imposed on the swivel seat and the handlebar, and the large load includes the axial force borne by the handlebar and the moment borne by the handlebar to flip toward one side of its own axis. This structure increases the spacing between the bearings at both ends of the swivel seat and the ability of the handlebar to withstand loads.

[0020] Preferably, the box body has a rigid wall, and the swivel seat is fixed to the outer wall of the rigid wall, thereby increasing the strength of the box body and the carrying capacity of the entire luggage case.

Accordingly, the handle bar can be locked or unlocked only by plugging and unplugging, which is convenient for locking or unlocking the handle bar.

[0022] Preferably, the lower end of the swivel seat is provided with a pedal that can be flipped between a pedal position and a folded position, and a latch is provided on the pedal; when the pedal is flipped to the pedal position, it deviates from the swivel seat and the latch is withdrawn from the first pin hole and the second pin hole; when the pedal is flipped to the folded position, it is close to the swivel seat and the latch is inserted into the first pin hole and the second pin hole. The pedal is used for electrically driving the luggage case to move, so that a person riding on the case can place his feet on the pedal, and it is convenient for the rider to apply force to the pedal with his feet to cause the handle to rotate to realize the steering of the luggage case. The latch is provided on the pedal, which takes into account the push-pull mode and the electric mode of the luggage case. When pushing and pulling the luggage case, there is no need to step on the pedal and flip the pedal to the folded position. When riding the luggage case, it is necessary to step on the pedal and flip the pedal to the pedal position. In addition, the pedal can be flipped by kicking, which is easy to operate.

[0023] Preferably, the latch is telescopically arranged on the pedal, the latch is extended out of the pedal by the elastic force of the elastic element, and when the foot steps on the pedal, the latch is stepped on to overcome the elastic force of the elastic element so that the latch is retracted into the pedal. Accordingly, when riding the suitcase, the foot is placed on the pedal without being hindered by the latch.

[0024] Preferably, the handle or / and the box body are provided with a power interface, and the power supply is separately configured from the box body and selectively connected to a power interface via a power cord to supply power to the driving wheel.

[0049] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] The terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a method or product comprising a series of technical features is not necessarily limited to those technical features clearly listed, but may also include other technical features that are not clearly listed and can be included in the method or product.

[0051] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Among them, "upper" and "lower", "left" and "right", "front" and "back" are opposite directions.

[0052] In the description of the present utility model, it is necessary to understand that the technical features defined by the terms "first", "second" and the like with sequential concepts are only for the purpose of clearly describing the defined technical features so that the defined technical features can be clearly distinguished from other technical features, but do not represent such naming in actual implementation, and therefore cannot be understood as a limitation of the present utility model.

[0053] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0054] like Figure 1-10 , Fig.12 As shown, the electric luggage case is intended to integrate the steering and pushing and pulling functions into the same handle, so that the luggage case can be steered by rotating the handle when electrically driven, and can be pushed and pulled by pushing and pulling the handle. To this end, the electric luggage case includes a case body 100, a driving wheel 200, a handle 300, an auxiliary wheel 400, and a locking structure.

[0055] like Figure 5 As shown, the box body 100 includes a frame 110 in the middle of the left and right parts and a first side cover 120 and a second side cover 130 mounted on the left and right sides of the frame. In order to facilitate the storage and access of luggage, at least one side cover can be opened. As shown in the figure, the left edge of the frame 110 is fastened to the sub-frame 140 by rivets, and the first side cover 120 cooperates with the sub-frame 140 by means of a lock or a zipper to open or close the box body. The second side cover 130 is directly fixed to the right edge of the frame 110 by rivets. Figure 5 The box structure shown is only an example, and the present invention does not limit the specific structure of the box. In order to increase the strength of the box, especially to provide a riding position for a person, the frame 110 is made of aluminum or aluminum alloy into a ring shape.

[0056] The driving wheel 200 is mounted on the bottom rear end of the box frame 110 and drives the box to move by the power provided by the power supply. The power provided by the power supply refers to the mechanical energy converted from electrical energy, such as the torque generated by the motor. In the illustrated structure, the driving wheel uses a wheel with a hub motor structure, that is, the axle of the driving wheel is fixed to the frame, and the tire part of the driving wheel rotates on the ground under the direct drive of the hub motor to provide power for the movement of the suitcase. The utility model does not limit the specific structure of the driving wheel. In other embodiments, the driving wheel can also use wheels with other structures, such as a motor driving the wheel through a transmission mechanism.

[0057] In the illustrated structure, there are two driving wheels 200 and they are coaxially arranged symmetrically with respect to the box 100 to stably support the box. In other embodiments, there may be only one driving wheel and it may be arranged at the left and right center position of the bottom of the box to reduce the manufacturing cost and weight of the product.

[0058] The handlebar 300 is assembled on the box 100 and rotates around its own axis relative to the box. In order to facilitate the steering, the handlebar 300 includes a vertical rod and two symmetrical grips 330 fixed to the upper end of the vertical rod, and the two grips are suitable for holding by hand when riding on the box.

[0059] There are two auxiliary wheels 400, which are fixedly mounted on the horizontal axis 401 at the lower end of the vertical rod and are spaced and coaxially arranged. Therefore, turning the handle 300 can turn the two auxiliary wheels 400. In the present invention, the auxiliary wheels do not provide power, so they can rotate more flexibly, which makes it easier to push and pull the suitcase when the suitcase is tilted and the driving wheels leave the ground.

[0060] The locking structure is used to lock the handle bar 300 to prevent the handle bar from rotating relative to the box body, or to unlock the handle bar to allow the handle bar to rotate relative to the box body.

[0061] The electric luggage case is placed in a push-pull mode when the handle is locked by the locking structure to prevent the handle from rotating relative to the case body. Fig.12 As shown, the luggage case is tilted relative to the ground 800, the auxiliary wheels are in contact with the ground 800, the driving wheels are off the ground 800, and the handle 300 is used as a push-pull rod to easily push and pull the luggage case. Since the handle is locked and cannot rotate relative to the case body, the case body is prevented from flipping relative to the handle when the tilted luggage case is pushed or pulled by the handle. In addition, since two spaced auxiliary wheels are provided, the entire luggage case can be stably supported when the tilted luggage case is pushed or pulled, and the luggage case is prevented from tipping over, so that the electric luggage case can be pushed or pulled like a trolley case.

[0062] In other embodiments, in order to prevent the suitcase from tipping over, there is one auxiliary wheel corresponding to the left and right center parts of the suitcase. In this case, the auxiliary wheel has a larger width, that is, the auxiliary wheel has a larger axial specification, which can also achieve the effect of the two auxiliary wheels arranged at intervals as shown in the figure.

[0063] The electric luggage case is placed in an electric mode when the handle is unlocked by the locking structure to allow the handle to rotate relative to the case body. At this time, the driving wheels and the auxiliary wheels are Figure 2 As shown, the luggage case is in contact with the ground 800, and the driving wheel drives the luggage case to move, and the electric luggage case is turned by turning the handle. Moreover, the case body is suitable for riding.

[0064] The electric luggage case has a handle that is locked and unlocked by a locking mechanism, and the steering and push-pull functions of the electric luggage case are integrated into the same handle. Compared with the electric luggage case in the prior art that is equipped with both a push-pull rod and a steering rod on the case body, the structure is simplified, the manufacturing cost is reduced, and the weight is small, making it easy to carry. Under the premise of setting the outer contour, it is conducive to increasing the storage space of the case body.

[0065] As shown in the figure, the driving wheel 200 of the electric suitcase is located at the rear of the bottom side of the suitcase, and the auxiliary wheel 400 is located at the front of the bottom side of the suitcase. When the suitcase is electrically driven forward according to usage habits, if the brakes are applied to stop the suitcase from moving forward, it is helpful to keep the suitcase stable and prevent it from tipping forward, which is safer for riding on the suitcase and avoids falling.

[0066] Furthermore, a cylindrical rotating seat 600 is fixed to the outer wall of the box 100, a first bearing 710 is arranged at the lower end of the rotating seat 600, and a second bearing 720 is arranged at the upper end of the rotating seat. The handlebar 300 is supported axially and radially by the first bearing and the second bearing and is rotatably assembled with the rotating seat. Accordingly, it is beneficial for the handlebar to rotate flexibly to achieve steering. In particular, the handlebar 300 is placed outside the box 100 and does not occupy the accommodation space in the box, so that the accommodation space in the box is basically consistent with the shape and contour of the box, keeps it regular, and improves the accommodation capacity. In addition, the handlebar is supported by the first bearing and the second bearing, thereby improving the ability to withstand external forces. For example, when a person sits on the box, a large load will be imposed on the rotating seat and the handlebar, and the large load includes the axial force borne by the handlebar and the torque borne by the handlebar to flip to one side of its own axis. The positional relationship between the cylindrical rotating seat and the first bearing and the second bearing increases the spacing between the bearings at both ends of the rotating seat and the ability of the handlebar to withstand loads.

[0067] like Figure 7-8 As shown, in order to adjust the length of the handlebar 300, the vertical rod includes a first rod 310 and a second rod 320. The first rod 310 is rotatably assembled on the swivel seat 600 through the first bearing and the second bearing, and the second rod 320 is inserted into the first rod 310. The length of the entire vertical rod is adjusted by the second rod 320 being telescopic relative to the first rod 310. The first rod and the second rod are locked together by a clamp 360 to fix the length of the vertical rod. The grip 330 is fixed to the upper end of the second rod 320.

[0068] like Figure 7-8 As shown, for ease of assembly, the first rod 310 is tubular and is inserted into the swivel seat 600. The first bearing 710 is mounted on the first rod 310 and axially positioned on the first rod, and the lower end of the swivel seat 600 is seated on the first bearing 710. The second bearing 720 is seated on the upper end of the swivel seat 600 and is mounted on the first rod 310. A nut 730 is threadedly connected to the first rod 310, and the second bearing 720 is pressed against the upper end of the swivel seat 600 by the nut 730. Accordingly, the first bearing 710 prevents the first rod 310 from moving upward relative to the swivel seat 600, and the second bearing 720 prevents the first rod 310 from moving downward relative to the swivel seat. The first rod 310 can flexibly rotate around its own axis relative to the swivel seat 600 but cannot move along its own axis, thereby ensuring the rotational assembly relationship between the first rod 310 and the swivel seat 600.

[0069] The upper end of the first rod 310 is covered with an adapter sleeve 340, and the adapter sleeve 340 has an open gap 341 along its length. The lower end of the adapter sleeve 340 is fastened to the upper end of the first rod 310 by a fastening sleeve 350. The upper end of the adapter sleeve 340 is covered with a clamp 360. The second rod 320 is inserted in the adapter sleeve 340 and the first rod 310 and can be extended relative to the first rod. In order to eliminate the shaking of the second rod 320 relative to the first rod 310 and to facilitate the flexible extension of the second rod 320 relative to the first rod, a bushing 370 is provided between the adapter sleeve 340 and the second rod 320. Generally, the first rod 310 and the second rod 320 are aluminum alloy tubes, and the bushing 370 is a plastic part. The bushing 370 also has an open gap 371 , and accordingly, when the clamp 360 is tightened, the adapter sleeve 340 and the bushing 370 each deform through their own open gaps to clamp the second rod 320 , and the second rod is connected to the first rod as a whole through the adapter sleeve.

[0070] In order to prevent the second rod 320 from rotating relative to the first rod 310, the hoop 360 is fixedly connected to the adapter sleeve 340 by means of a screw 380, a guide block 361 is provided on the hoop 360, and a guide groove 321 is provided on the second rod 320 along its length direction, and the guide block 361 is located in the guide groove 321 to guide the extension of the second rod and prevent the second rod from rotating relative to the first rod. In addition, a blocking portion 322 is provided at the lower end of the guide groove 321, and the blocking portion 322 blocks the guide block 361 to limit the second rod, so that the second rod cannot be withdrawn from the first rod.

[0071] The aforementioned structure of adjusting the length of the vertical rod by telescoping the second rod relative to the first rod is only illustrative, and in other embodiments, other structural forms may be used to achieve length adjustment. Or there is only one first rod, which is equivalent to the first rod and the second rod being made as one body.

[0072] As mentioned above, the box body 100 has a frame 110, and the frame 100 forms a rigid wall 111. The swivel seat 600 is fixed to the outer wall of the rigid wall 111. Accordingly, the strength of the box body and the carrying capacity of the entire suitcase are increased. In order to increase the assembly strength of the swivel seat and the rigid wall, the swivel seat 600 has a clamping portion 601, and the clamping portion 601 is close to the outer wall of the rigid wall 111. A clamping member 603 is arranged close to the inner wall of the rigid wall 111, and the clamping portion 601 and the clamping member 603 are fastened together by fasteners such as rivets or screws to clamp the rigid wall 111 between the clamping portion and the clamping member. Accordingly, the assembly of the swivel seat is achieved on a larger area of ​​the rigid wall, and the assembly strength is ensured.

[0073] In the illustrated structure, the locking structure includes a latch 501, a first pin hole 602 provided on a rotating seat 600, and a second pin hole 311 provided on a first rod 310 of the handle. When the latch is withdrawn from the first pin hole and the second pin hole, the handle is allowed to rotate relative to the box body, and when the latch is inserted into the first pin hole and the second pin hole, the handle is prevented from rotating relative to the box body. Accordingly, the handle can be locked or unlocked only by plugging and unplugging, which is convenient for locking or unlocking the handle.

[0074] In particular, the lower end of the swivel 600 is provided with a Figure 1 , Figure 3 , Figure 5-6 The footrest positions shown are similar to Figure 9-10 The pedal 610 is flipped between the folded positions shown, and the latch 501 is arranged on the pedal 610. When the pedal is flipped to the pedal position, it deviates from the swivel seat and the latch is withdrawn from the first pin hole and the second pin hole. When the pedal is flipped to the folded position, it is close to the swivel seat and the latch is inserted into the first pin hole and the second pin hole. The pedal is used for electrically driving the luggage case to move, so that the person riding on the case can put his feet on the pedal, and it is convenient for the rider to apply force to the pedal with his feet to cause the handle to rotate to realize the turning of the luggage case. The latch is arranged on the pedal, which takes into account the push-pull mode and the electric mode of the luggage case. When pushing and pulling the luggage case, there is no need to step on the pedal and flip the pedal to the folded position. When riding the luggage case, it is necessary to step on the pedal and flip the pedal to the pedal position. In addition, the pedal can be flipped by kicking, which is easy to operate.

[0075] Furthermore, the latch 501 is telescopically arranged on the pedal 610, and the latch 501 extends out of the pedal 610 by the elastic force of the elastic element 502. When the foot steps on the pedal, stepping on the latch overcomes the elastic force of the elastic element 502 and retracts the latch 501 into the pedal 610. Accordingly, when riding the suitcase, the foot is placed on the pedal without being hindered by the latch.

[0076] And, if Fig.11As shown, the pedal 610 is assembled on the swivel seat 600 through a pin shaft to achieve flipping, and a positioning pit 604 and a positioning ball 611 are separately provided on the pedal 610 and the swivel seat 600. The rear side of the positioning ball 611 supports a spring 612. When the pedal is in the pedal position and the retracted position, the positioning ball 611 is located in the corresponding positioning pit 604 due to the elastic force of the support spring 612 to position the pedal in the pedal position or the retracted position.

[0077] In other embodiments, it is permitted to not configure the footrest, in which case the latch can be configured separately and attached to the luggage case. Alternatively, in other embodiments, the locking structure is not the matching relationship between the latch and the first pin hole and the second pin hole, but can be other structures that can replace the latch and the first pin hole and the second pin hole to lock the handle to prevent the handle from rotating relative to the box body or unlock the handle to allow the handle to rotate relative to the box body.

[0078] In the illustrated structure, a power interface 331 is provided on the handle 330 of the handlebar 300, and the box body is provided with exposed and built-in power interfaces not shown in the figure. The power supply is separately configured with the box body and is plugged into one of the power interfaces via a power cord to power the drive wheel. When the power supply is plugged into the power interface on the handlebar or the exposed power interface on the box body to power the drive wheel, it is preferred to carry the power supply with you, such as in a backpack or a shoulder bag, which is conducive to separating the power supply from the suitcase when dragging the suitcase or placing the suitcase in a vehicle. Preferably, a power bank that is suitable for taking a vehicle and carrying with you is used as a power source, which can power the electric suitcase and charge mobile devices such as mobile phones and tablet computers. In addition, by configuring the power supply in this way, it is not necessary to set a power supply compartment on the box body, so that the storage space in the box body is basically consistent with the shape and contour of the box body, keeping it regular and improving the storage capacity.
