Description

Technical Field

[0001] This application relates to the field of lever extension control, and in particular to an automatic reset luggage lever. Background Technology

[0002] With the continuous growth of travel demand, luggage has become an indispensable tool in people's daily lives. As a crucial component of luggage, the design of the handle directly impacts the convenience of using the bag. Adjustable, extendable handles make it easy to pull the bag while walking, greatly enhancing the travel experience. In recent years, luggage design has trended towards miniaturization and lightweighting, meeting people's needs for convenient carrying. This trend makes luggage more space-saving during storage and transportation, reducing the burden on people, and thus becoming increasingly popular in the market, especially in line with the trend of modern fast-paced life. It allows people to more easily handle luggage carrying issues whether commuting daily, traveling for business, or vacationing, further promoting the convenience and efficiency of travel. From individual consumers to corporate users, everyone can benefit from this miniaturized and lightweight luggage design, driving the vigorous development of the entire luggage industry. In existing luggage, when it is necessary to reset the handle, the user usually has to first press the unlocking device to release the handle's lock, and then manually push the handle downwards to complete the storage. However, when staff need to carry multiple bags, they have to perform the above operation on each handle individually, requiring two steps each time: pressing to unlock and pressing down, making the entire storage process extremely cumbersome. In transportation hubs such as airports and train stations, staff need to quickly move large quantities of bags to ensure smooth passenger travel; in warehouses, staff need to efficiently organize numerous goods, and the existing handle reset operation consumes a significant amount of time and effort. Moreover, this method is prone to oversights in busy scenarios, affecting the accuracy and smoothness of the overall work. Especially for high-end market consumers, who not only demand small size and basic performance in bags but also require greater convenience, this cumbersome operation can severely impact the progress of transportation and reduce work efficiency, particularly in scenarios with high efficiency requirements. The existing handle reset method clearly cannot meet the expectations of this group for efficient and convenient bag use, limiting the further development of bags in the high-end market. Utility Model Content

[0003] In order to meet the requirements of miniaturization of luggage, improve the efficiency and convenience of pull rod storage, reduce the consumption of time and effort, and enhance the user experience of luggage, this application provides an automatic reset luggage pull rod.

[0004] This application provides a luggage handle, including a handle assembly and a limiting assembly. The handle assembly includes a fixed rod fixed to the luggage, a telescopic rod extending within the fixed rod, and a handle. The limiting assembly is used to adjust the connection position between the fixed rod and the telescopic rod. It also includes a reset assembly, which includes a tape reel and a retractable component. The retractable component is disposed on the fixed rod, one end of the tape reel is disposed on the telescopic rod, and the other end is connected to the retractable component. The retractable component is used to automatically rewind the tape reel. By adopting the above technical solution, due to the reset assembly, where the retractable component is disposed on the fixed rod, one end of the tape reel is disposed on the telescopic rod, and the other end is connected to the retractable component, and the retractable component can achieve automatic tape rewinding. When the telescopic rod is pulled out, the tape retracts, and the retractable component stores elastic potential energy; when the handle is no longer needed in a stretched state, the retractable component releases the elastic potential energy, causing the tape to automatically rewind. During the tape rewinding process, the telescopic rod is pulled back into the fixed rod, thus achieving automatic reset of the luggage handle. This design avoids the cumbersome operation of manually pushing down the lever to retract luggage, which is especially beneficial for staff carrying multiple bags or in busy situations. It significantly improves the efficiency and convenience of lever retraction, reducing time and effort spent and minimizing the possibility of oversights due to cumbersome operation. This better meets the expectations of high-end consumers for efficient and convenient luggage use. Preferably, the retraction component includes: a roll shell, a fixed shaft, a winding strap, and a coil spring wound within the roll shell. The fixed shaft passes through the middle of the roll shell and is positioned on the fixed rod. The roll shell can rotate around the fixed shaft. One end of the coil spring is fixed to the fixed shaft, and the other end is fixed to the roll shell. The winding strap is wound around the outer wall of the roll shell, with one end fixed to the roll shell and the other end connected to the telescopic rod. When the telescopic rod is pulled out, the winding strap causes the roll shell to rotate around the fixed shaft, tightening the coil spring. By adopting the above technical solution, when the telescopic rod is pulled out, the tape, connected at one end to the telescopic rod and fixed at the other end to the roll shell, is stretched, causing the roll shell to rotate around the fixed axis. The coil spring, fixed at one end to the fixed axis and at the other end to the roll shell, is tightened by the rotation of the roll shell, storing elastic potential energy. When the telescopic rod needs to be reset, the tightened coil spring releases its elastic potential energy, causing the roll shell to rotate in the opposite direction, thus automatically rewinding the tape. This eliminates the need to manually push the rod down after pressing the unlocking device, as in existing methods. Simply releasing the lock between the telescopic rod and the fixed rod allows the telescopic rod to automatically reset under the action of the coil spring and tape, greatly simplifying the operation of retracting the rod. This is especially beneficial for staff who need to carry multiple bags, such as airport and train station workers and warehouse managers, saving significant time and effort, improving work efficiency, and reducing the possibility of oversights due to cumbersome operations in busy situations. It meets the expectations of high-end consumers for efficient and convenient use of bags and adapts to the trend of modern fast-paced life.Preferably, the roll shell includes a fixed plate and an annular collar, the annular collar being disposed on the fixed plate, a fixed shaft passing through the fixed plate, a coil spring wound around the fixed shaft within the annular collar, and a roll of tape wound around the outer wall of the annular collar. By adopting the above technical solution, since the roll shell includes a fixed plate and an annular collar, with the fixed shaft passing through the fixed plate and the coil spring wound around the fixed shaft within the annular collar, this structure allows the coil spring to stably wind and release energy within the space defined by the annular collar. When the telescopic rod is pulled out, the roll of tape drives the roll shell to rotate around the fixed shaft, thereby tightening the coil spring and storing elastic potential energy. The roll of tape wound around the outer wall of the annular collar ensures the regularity of the roll winding and avoids tangling or disorder during the winding process. When the telescopic rod needs to be reset, the coil spring releases its elastic potential energy, causing the roll shell to rotate in the opposite direction. This automatically rewinds the tape and pulls the telescopic rod back into the fixed rod, simplifying the reset operation of the luggage handle. Users no longer need to manually push the rod downwards until it retracts into the fixed rod, improving ease of use. This is especially suitable for scenarios requiring the rapid handling of large quantities of luggage, such as transportation hubs like airports and train stations, as well as warehouses, saving time and effort and improving work efficiency. Preferably, the fixed rod is provided with a placement slot, in which the roll shell, tape, and coil spring are all accommodated. By adopting the above technical solution, the fixing rod is provided with a placement groove, which accommodates the roll shell, roll tape, and spring, preventing these components from being exposed to the outside and damaged by external factors such as collision, friction, or dust, thus extending their service life. At the same time, this integrated design makes the bag handle structure more compact, reducing the space occupied and facilitating the miniaturization and lightness of bags, making them easier to carry and more in line with current bag design trends. Furthermore, storing all components in the placement groove also makes the bag handle look neater and more aesthetically pleasing. Preferably, the fixing rod is provided with a guide channel, which communicates with the placement groove. The roll tape in the placement groove passes through the guide channel and connects to the telescopic rod. By adopting the above technical solution, because the fixing rod is provided with a guide channel and this guide channel communicates with the placement groove, the roll tape in the placement groove can smoothly pass through the guide channel and connect to the telescopic rod. In this way, during the extension and retraction of the telescopic rod, the roll tape can move orderly along the guide channel, avoiding tangling or deviation of the roll tape during movement. Furthermore, the guide channel provides a clear path for the movement of the tape, ensuring the stability and reliability of the connection between the tape and the telescopic rod. This, in turn, ensures that the reset component can function more effectively, realizing the automatic reset function of the luggage handle and improving the convenience of luggage use. Preferably, the inner wall of the guide channel of the fixing rod extends with two abutment portions, forming a limiting channel between the two abutment portions. The tape passes through the limiting channel, and the two abutment portions abut against both sides of the tape respectively, thereby limiting the winding speed of the tape.By adopting the above technical solution, two abutment parts are extended into the inner wall of the guide channel of the fixed rod, forming a limiting channel between the two abutment parts. When the tape passes through the limiting channel, the two abutment parts abut against both sides of the tape respectively. Thus, when the shrinking component drives the tape to automatically rewind, friction is generated between the abutment parts and the tape. As the tape continues to contact the abutment parts during the rewinding process, the friction continuously acts on the tape, effectively limiting the rewinding speed. This avoids the tape from tangling and knotting due to excessive rewinding speed, and also reduces the possibility of the tape colliding and being damaged by other components during high-speed rewinding, ensuring the stability and reliability of the tape rewinding process, thereby improving the service life and performance of the entire luggage handle reset function. Preferably, the guide channel has an arc-shaped transition surface near the entrance of the placement slot, and the tape enters the guide channel along the arc-shaped transition surface. By adopting the above technical solution, the arc-shaped transition surface at the entrance of the guide channel near the placement slot allows the tape to enter the guide channel more smoothly, reducing friction and resistance when the tape enters the guide channel, ensuring the smoothness of the tape winding process, avoiding tape jamming and friction damage, thereby improving the reliability and stability of the automatic reset function of the luggage handle. Preferably, the limiting component includes a pressing member and a movable limiting member, the pressing member and the movable limiting member are connected, the pressing member is disposed on the handle, and the movable limiting member is disposed on the telescopic rod. Pressing the pressing member releases the limiting fixation between the telescopic rod and the fixed rod. By adopting the above technical solution, since the pressing member is disposed on the handle and the movable limiting member is disposed on the telescopic rod and the two are connected, when the user holds the handle and presses the pressing member, the force can be directly transmitted to the movable limiting member. In this way, the movable limiting component can release the limiting fixation between the telescopic rod and the fixed rod. Users no longer need to bend over to find the unlocking point; they can easily complete the unlocking operation while holding the handle, making operation more convenient and effortless. This effectively improves the efficiency of adjusting the luggage handle, especially in scenarios involving rapid movement or frequent adjustments to the handle length, greatly enhancing the user experience. Preferably, the fixed rod has two vertically arranged limiting holes, and the movable limiting component has a protrusion that can extend and retract within either of the limiting holes to restrict relative movement between the fixed rod and the telescopic rod.By adopting the above technical solution, the fixed rod is vertically equipped with two limiting holes, and the movable limiting component is equipped with a protrusion. When the telescopic rod is stretched or retracted to a suitable position, the protrusion can extend and engage with the corresponding limiting hole. Utilizing the blocking effect of the limiting hole on the protrusion, the relative movement between the fixed rod and the telescopic rod can be effectively restricted, allowing the telescopic rod to be stably maintained in that position. This prevents unnecessary extension or retraction of the rod due to accidental shaking or force during use, improving the stability and reliability of the luggage handle. At the same time, when it is necessary to adjust the position of the telescopic rod, simply retract the protrusion to disengage it from the limiting hole, and the telescopic rod can be moved within the fixed rod. The operation is convenient and quick, improving the user's convenience in adjusting the length of the handle. Preferably, the pressing component includes a pressing part, a crossbeam portion disposed within the handle, and a spring. The pressing part and the crossbeam portion are integrally formed. The handle has an opening, the pressing part passes through the opening and protrudes from the handle surface, the crossbeam portion has two through holes on both sides of the pressing part, and the handle has two cylinders corresponding to the through holes, each cylinder passing through one of the through holes. The two ends of the spring are respectively connected to the pressing part and the handle, and the crossbeam portion is connected to the movable limiting component. By adopting the above technical solution, the pressing part and the crossbeam portion are integrally formed, and the pressing part passes through the handle opening and protrudes from the handle surface. This design facilitates user operation by pressing. The crossbeam portion has two through holes on both sides of the pressing part, and the handle has two corresponding cylinders passing through the through holes, which guides and stabilizes the movement of the crossbeam portion, making the pressing action smoother and more accurate. The spring is connected to the pressing part and the handle at both ends. When the pressing part is pressed, the spring is compressed, generating elastic force. After the pressing part is released, the elastic force of the spring causes the pressing part to automatically return to its initial position. At the same time, the crossbeam is connected to the movable limiter. When the pressing part is pressed, the crossbeam drives the movable limiter to move, thereby releasing the limiting fixation between the telescopic rod and the fixed rod. After the pressing part is released, the pressing part and the crossbeam return to their original positions under the action of the spring, and the movable limiter can also limit and fix the telescopic rod and the fixed rod again, realizing convenient and reliable limiting operation and improving the flexibility and stability of the extension and fixation of the luggage handle during use.

[0005] In summary, this application includes at least one of the following beneficial technical effects:

[0006] 1. When the telescopic rod is pulled out, the tape roll drives the housing to rotate around the fixed axis, tightening the coil spring and storing elastic potential energy. Then, when the rod needs to be retracted, the retraction mechanism automatically winds up the tape roll, releasing the elastic potential energy of the coil spring and causing the housing to rotate, thus automatically winding up the tape roll and pulling the telescopic rod back into the fixed rod. This achieves automatic retraction of the rod, eliminating the need to manually push the rod downwards, simplifying the rod retraction process.

[0007] 2. Because the pull rod can automatically retract, when carrying multiple bags, staff no longer need to go through the two steps of unlocking and pressing down on each pull rod individually, as in the past. This avoids repetitive and tedious operations, greatly saves time and effort in retracting the pull rod, and significantly improves work efficiency.

[0008] 3. In busy environments such as airports and train stations, the automatic retractable handle reduces manual operation, lowers the possibility of oversights, and improves overall accuracy and smoothness. For high-end consumers, this convenient operation meets their high demands for convenient luggage functionality and fulfills their expectations for efficient luggage use. Attached Figure Description

[0014] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0015] This application provides an embodiment of an automatic reset luggage handle, referring to... Figure 1 and Figure 2 The luggage handle includes a handle assembly 1, a limiting assembly 2, and a reset assembly 3. The limiting assembly 2 and the reset assembly 3 are both installed on the handle assembly 1. The handle assembly 1, the limiting assembly 2, and the reset assembly 3 work together to enable the luggage handle to achieve the functions of stretching, fixing, and automatic reset, which solves the problem of cumbersome reset operation of existing luggage handles and improves the convenience of use and work efficiency.

[0016] In this embodiment, the pull rod assembly 1 includes two fixed rods 11, two telescopic rods 12, and a handle 13. The two fixed rods 11 are symmetrically fixed inside the bag and cannot move. The two telescopic rods 12 slide and extend within the two fixed rods 11. The fixed rods 11 are hollow tubular structures, facilitating the telescopic rods 12 to extend and retract within them. The two telescopic rods 12 are connected by the handle 13, which is located at the end of each telescopic rod 12 furthest from the fixed rods 11, i.e., at the top of the two telescopic rods 12, allowing the user to easily pull the bag. The outer diameter of the telescopic rod 12 is slightly smaller than the inner diameter of the fixed rod 11, with a certain gap between them to ensure that the telescopic rod 12 can slide smoothly within the fixed rod 11. For example, the fixed rods 11 and the telescopic rods 12 can be made of aluminum alloy, a material that is lightweight and high-strength. Specifically, this embodiment has two limiting components 2, used to adjust the connection position between the fixed rods 11 and the telescopic rods 12, which include a pressing component 21 and a movable limiting component 22. The pressing component 21 includes a pressing part 211, a crossbeam part 212, and a spring 213. After the pressing component 21 is assembled, at least a portion of the pressing part 211 is located on the outer surface of the handle 13, while the crossbeam part 212 and the spring 213 are located inside the handle 13. The pressing part 211 and the crossbeam part 212 are integrally formed, forming an inverted "T" shape. Specifically, the upper surface of the handle 13 is provided with an opening, and the pressing part 211 passes through the opening and protrudes from the upper surface of the handle 13, making it convenient for the user to press. The crossbeam part 212 is provided with two through holes on both sides of the pressing part 211. The handle 13 is provided with two cylinders corresponding to the positions of the through holes. The cylinders pass through the through holes to allow the crossbeam part 212 to move up and down inside the handle 13. The two ends of the spring 213 are respectively connected to the pressing part 211 and the handle 13. The two sides of the crossbeam part 212 are respectively connected to two movable limiting members 22 for simultaneously adjusting the connection position between the two telescopic rods 12 and the two fixed rods 11. When the user presses the pressing part 211, the crossbeam 212 moves downward against the elastic force of the spring 213, thereby driving the movable limiting member 22 to move. When the pressing part 211 is released, the spring 213 returns to its original state, causing the pressing part 211 and the crossbeam 212 to return to their initial positions. Specifically, in this embodiment, the two movable limiting members 22 are provided with protrusions 221, and the fixing rod 11 has two vertically arranged limiting holes. The protrusions 221 can extend and retract into either limiting hole to restrict the relative movement of the fixing rod 11 and the telescopic rod 12. When the protrusions 221 are inserted into the limiting holes, the telescopic rod 12 is fixed in its current position; when the pressing part 21 is pressed, causing the movable limiting member 22 to move, the protrusions 221 retract inward from the limiting holes, allowing the telescopic rod 12 to extend and retract freely within the fixing rod 11. The movable limiting member 22 in this embodiment is commonly used in existing bags and will not be described in detail here. (Refer to...) Figure 3Specifically, in this embodiment, the two reset components 3 are respectively disposed on the pull rod components 1 on both sides of the handle 13, and both adopt a double-roll structure system, including a roll 31 and a shrinking component 32. The shrinking component 32 includes a roll shell 321, a fixed shaft 322, and a coil spring 323 wound inside the roll shell 321. The fixed shaft 322 passes through the roll shell 321 so that the roll shell 321 can rotate around the shaft. The two ends of the roll shell 321 are respectively disposed on the fixed shaft 322 and the roll shell 321. The two ends of the roll 31 are respectively connected to the roll shell 321 and the telescopic rod 12 so that the telescopic rod 12 can move with the roll 31. The coil spring 323 is wound inside the roll shell 321. Specifically, in this embodiment, the roll shell 321 is composed of a rigid fixed plate and an integrally formed annular winding cavity. The annular winding cavity protrudes along the axial direction of the fixed plate to form an annular guide rail. The central shaft passes through the central hole of the fixed plate and forms a rigid connection with the fixed rod 11. The coil spring 323 adopts a constant torque planar spiral structure. Its inner end is fixed to the axial positioning groove of the central shaft by a positioning pin, and its outer end is connected to the inner wall fixing ring of the annular winding cavity by a snap-fit ​​structure. The coil spring 323 is tightened to form an energy storage pre-tightening structure.

[0017] In this embodiment, the two winding tapes 31 are made of high-strength polyester fiber substrate. One end is fixed to the outer edge of the annular guide rail of the casing 321 by riveting, forming a multi-layered spiral winding along the guide rail surface. When the telescopic rod 12 moves axially, the winding tape 31 drives the casing 321 to rotate around the central axis through a friction transmission mechanism. At this time, the coil spring 323 generates controllable deformation to store energy. This design achieves energy conversion through a dual-winding cooperative working mechanism: the coil spring 323 accumulates elastic potential energy during winding, and the winding tape 31 transmits driving force during unwinding, forming a composite reset system with bidirectional damping characteristics. When the external force is removed, the coil spring 323 releases its stored energy to drive the casing 321 to rotate in the opposite direction, causing the winding tape 31 to automatically retract into the annular guide rail of the casing 321, realizing the automatic reset function of the actuator. (Refer to...) Figure 4 Specifically, in this embodiment, both fixing rods 11 are provided with placement grooves 111, housing the roll shell 321, the roll 31, and the coil spring 323, which are symmetrically arranged on both sides of the handle 13. The placement grooves 111 accommodate the roll shell 321, the roll 31, and the coil spring 323, thus protecting these components from external factors and making the entire structure more compact. The fixing rods 11 are also provided with guide channels 112, which communicate with the placement grooves 111, allowing the roll 31 in the placement grooves 111 to pass through the guide channels 112 and connect to the telescopic rod 12. Furthermore, the guide channel 112 has an arc-shaped transition surface near the entrance of the placement grooves 111. The roll 31 conforms to the arc-shaped transition surface when entering the guide channel 112, reducing the frictional resistance of the roll 31 when entering the guide channel 112 and making the movement of the roll 31 smoother. (Refer to...) Figure 4Specifically, the inner walls of the guide channels 112 of the two fixing rods 11 each extend with two abutment portions 113. A limiting channel is formed between the two abutment portions 113, allowing the winding tape 31 to pass through. After entering the guide channel 112, the winding tape 31 passes through the limiting channel, and the two abutment portions 113 abut against both sides of the winding tape 31 respectively. This generates friction between the abutment portions 113 and the winding tape 31 during winding, limiting the winding speed of the winding tape 31. In this way, impact and damage caused by excessively fast winding of the winding tape 31 can be avoided. To protect the structure of the roll shell 321, the winding tape 31, and the coil spring 323, sleeves are also provided at the lower ends of the two fixing rods 11 to protect the roll shell 321, the winding tape 31, and the coil spring 323, preventing collisions. The implementation principle of this embodiment is as follows: the automatic reset luggage pull rod achieves the automatic reset function of the pull rod through the coordinated work of the pull rod assembly 1, the limiting assembly 2, and the reset assembly 3. In use, the user holds handle 13 and pulls the telescopic rod 12 upwards. The telescopic rod 12 extends upwards within the fixed rod 11, while the winding belt 31 drives the winding shell 321 to rotate around the fixed shaft 322, tightening the coil spring 323. When the telescopic rod 12 extends to the appropriate position, the protrusion 221 of the movable limiting member 22 inserts into the limiting hole of the fixed rod 11, fixing the telescopic rod 12 in place. When it is necessary to reset the rod, the user presses the pressing member 21 on handle 13, causing the protrusion 221 of the movable limiting member 22 to retract from the limiting hole, releasing the limitation between the telescopic rod 12 and the fixed rod 11. At this time, the tightened coil spring 323 releases its elastic potential energy, causing the winding shell 321 to rotate in the opposite direction, thereby automatically winding the winding belt 31 and pulling the telescopic rod 12 back into the fixed rod 11, achieving automatic reset of the rod. This design simplifies the storage operation of the handle, eliminating the need for users to manually push the handle down, greatly improving storage efficiency. It is especially suitable for scenarios where multiple bags need to be carried, meeting the needs of high-end market consumers for efficient and convenient use of bags.

[0018] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
