Description

Technical Field

[0001] This application relates to the field of luggage accessories, and in particular to a novel luggage handle structure. Background Technology

[0002] The luggage handle features a multi-section telescopic design to adjust the overall length of the handle, accommodating the needs of users of different heights. It also uses lightweight aluminum material to ensure both durability and portability, and its stable load-bearing capacity helps improve the user's balance and comfort during use.

[0003] Among them, Chinese utility model patent, patent number: CN211703741U, discloses a luggage handle that can be locked and unlocked by pressing. The technical solution includes a fixed rod, a pressing locking device, and a movable rod. The fixed rod has a receiving cavity. The pressing locking device is fixed to the lower end of the receiving cavity and has a clamping groove that can be opened and closed by pressing. The movable rod is movably disposed in the receiving cavity. The lower end of the movable rod is fixed with a ball head that matches the pressing locking device. The ball head has a clamping head that matches the clamping groove. The upper end of the movable rod extends upward beyond the upper end of the fixed rod. By setting a pressing locking device in the fixed rod and a ball head on the movable rod, the clamping head on the ball head and the clamping groove on the pressing locking device cooperate to achieve locking and unlocking. The structure is simple and not easily damaged, and it can quickly switch between fixed and fixed states, making the sliding of the handle smoother and greatly improving the user experience, which is conducive to its widespread application.

[0004] Therefore, conventional suitcases use a combination of unlocking and telescopic mechanisms. When users need to extend or retract the suitcase handle, they must first unlock the telescopic mechanism using the unlocking mechanism. The moment the unlocking mechanism is activated, the telescopic mechanism is subjected to the force applied by the unlocking mechanism, and the unlocking mechanism will extend or retract the telescopic handle in an orderly manner. However, the unlocking mechanism of this type of handle structure has a relatively complex mechanical structure. With the increase of usage time, irreversible mechanical wear is prone to occur between the components, leading to difficulty in unlocking, reduced stability, and room for improvement. Utility Model Content

[0005] To facilitate unlocking of the telescopic mechanism, this application provides a novel luggage handle structure.

[0006] The novel luggage handle structure provided in this application adopts the following technical solution:

[0007] A novel luggage handle structure includes a main frame, a drive unit, a power transmission rod, and an unlocking rod. The drive unit is movably connected to the main frame, and the unlocking rod is slidably disposed within the main frame. The power transmission rod is located between the drive unit and the unlocking rod, with one end of the power transmission rod abutting against the drive unit and the other end abutting against the end face of the unlocking rod. The end of the unlocking rod away from the end abutting against the power transmission rod is used to connect to a telescopic mechanism. When the drive unit is activated, it drives the power transmission rod to rotate along the main frame and drives the unlocking rod to slide along the main frame.

[0008] By adopting the above technical solution, since the driving component is movably connected to the main frame, when the user applies force to the driving component, the driving component will move along the main frame. When the driving component moves, it will drive the power transmission rod that abuts against the driving component to rotate along the main frame. When the power transmission rod rotates along the main frame, it will also drive the unlocking rod to move along the main frame, thereby realizing the action of the telescopic mechanism connected to the unlocking rod, and realizing the purpose of unlocking the telescopic mechanism. The simple mechanical structure plays a positive guiding role in improving the convenience of unlocking the telescopic mechanism.

[0009] Preferably, a limiting groove is provided on the main frame, and the driving component is slidably disposed in the limiting groove. When a force is applied to the driving component, the driving component slides along the limiting groove.

[0010] By adopting the above technical solution, the path of the driving component sliding along the main frame is limited by the limiting groove, which helps to reduce the shaking of the driving component when it moves, and reduces the probability of the driving component getting stuck when it moves along the main frame due to excessive movement of the driving component along the main frame.

[0011] Preferably, the main frame is symmetrically provided with two sets of reset springs along the centerline along the length direction. The fixed ends of the two sets of reset springs abut against the main frame, and the free ends of the two sets of reset springs abut against the two ends of the driving member along the length direction. The two sets of reset springs are used to drive the driving member to reset along the main frame.

[0012] By adopting the above technical solution, the driving component is driven to reset along the main frame by two sets of symmetrically arranged reset springs. The mechanical structure is simple and highly stable, reducing the probability of the driving component failing to reset quickly when it moves, thus affecting the user experience.

[0013] Preferably, the power transmission rod has an integrally formed pivot in the middle section along its length, and the pivot is rotatably connected to the main frame.

[0014] By adopting the above technical solution, the rotational connection between the power transmission rod and the main frame is realized through the integrally molded rotating shaft, which helps to reduce the resistance encountered by the power transmission rod when it moves along the main frame and improves the stability of the power transmission rod when it moves along the main frame.

[0015] Preferably, the main frame has a guide groove, and the unlocking rod slides in conjunction with the guide groove.

[0016] By adopting the above technical solution, since the unlocking rod is connected to the telescopic mechanism, the limiting and guiding effect of the guide groove improves the stability of the unlocking rod sliding along the main frame, so that the unlocking rod can slide smoothly along the main frame.

[0017] Preferably, a limiting cover is provided on the guide groove, and a buckle is provided on both sides of the limiting cover along the width direction. The limiting cover is engaged with the guide groove by the buckle.

[0018] By adopting the above technical solution, the unlocking rod located in the guide groove is protected by the limiting cover, which reduces the probability that the unlocking rod will fall off the guide groove due to excessive force when it slides along the guide groove. The limiting cover is fastened to the guide groove by a buckle, which improves the convenience of installing the limiting cover in the guide groove. The mechanical structure is simple and has high stability.

[0019] Preferably, a soft pad is provided on the main frame located on one side of the limiting groove.

[0020] By adopting the above technical solution, the soft padding improves the user's comfort when holding the main frame and enhances the user experience.

[0021] Preferably, a wear-resistant part is provided on the end face of the drive component that abuts against the power transmission rod, and the wear-resistant part is a wear-resistant part made of Teflon.

[0022] By adopting the above technical solution, when the user presses the drive component and moves along the main frame, the power transmission rod will be in a state of mutual friction with the drive component. The wear-resistant part helps to reduce the resistance between the drive component and the power transmission rod, and reduces the probability of the drive component and / or the power transmission rod wearing out too quickly due to excessive friction.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Because the driving component is movably connected to the main frame, when the user applies force to the driving component, the driving component will move along the main frame. When the driving component moves, it will drive the power transmission rod that abuts against the driving component to rotate along the main frame. When the power transmission rod rotates along the main frame, it will also drive the unlocking rod to move along the main frame, thereby realizing the action of the telescopic mechanism connected to the unlocking rod, and realizing the purpose of unlocking the telescopic mechanism. The simple mechanical structure plays a positive guiding role in improving the convenience of unlocking the telescopic mechanism.

[0025] 2. Two sets of symmetrically arranged reset springs drive the driving component to reset along the main frame.

[0026] The mechanical structure is simple and highly stable, reducing the probability of situations where the driving component cannot quickly reset when it moves, thus affecting the user experience.

[0027] 3. Limiting the sliding path of the drive component along the main frame using the limiting groove helps reduce the impact on the drive component.

[0028] The shaking during operation reduces the probability of the drive component getting stuck when moving along the main frame due to excessive movement along the main frame. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses a novel luggage handle structure. (Refer to...) Figures 1-3A novel luggage handle structure includes a main frame 1, a drive unit 2, a power transmission rod 3, and an unlocking rod 4. The drive unit 2 is movably connected to the main frame 1. The unlocking rod 4 is slidably disposed within the main frame 1. The power transmission rod 3 is located between the start button and the unlocking rod 4, with one end of the power transmission rod 3 abutting against the drive unit 2 and the other end of the power transmission rod 3 abutting against the end face of the unlocking rod 4. The end of the unlocking rod 4 away from the end abutting against the power transmission rod 3 is used to connect to a telescopic mechanism. When the drive unit 2 is activated, the drive unit 2 drives the power transmission rod 3 to rotate along the main frame 1 and drives the unlocking rod 4 to slide along the main frame 1.

[0035] It should be noted that there are two sets of power transmission rods 3. The two sets of power transmission rods 3 have the same components and forming method, and the two sets of power transmission rods 3 are symmetrically arranged on the main frame 1 located on both sides of the drive component 2 about the drive component 2. The following description will take one set of power transmission rods 3 for detailed explanation.

[0036] Specifically, the main frame 1 includes a main frame 11, a bottom cover 12, and a cover plate 13. The outer contour of the main frame 11 is U-shaped. The bottom cover 12 covers the main frame 11, thereby forming a cavity between the main frame 11 and the bottom cover 12 for accommodating the drive component 2, the power transmission rod 3, and the unlocking rod 4. When the drive component 2, the power transmission rod 3, and the unlocking rod 4 are located in the cavity, they can be covered by the cover plate 13, making the installation method simple.

[0037] Furthermore, a limiting groove 5 is formed on the main frame 1, and the driving component 2 is slidably disposed within the limiting groove 5. When a force is applied to the driving component 2, the driving component 2 slides along the limiting groove 5. The limiting groove 5 is located on the bottom cover 12, formed by extending through the bottom cover 12 along its thickness direction, and is located at the midpoint of the bottom cover 12 along its length direction. The contour of the limiting groove 5 matches the outer contour of the driving component 2, and the tolerance dimensions of the limiting groove 5 and the driving component 2 are in a clearance fit, thereby allowing the driving component 2 to slide smoothly along the limiting groove 5.

[0038] Therefore, limiting the path of the drive component 2 along the main frame 1 by limiting the groove 5 helps to reduce the shaking of the drive component 2 when it moves, and reduces the probability of the drive component 2 getting stuck when it moves along the main frame 1 due to excessive movement of the drive component 2 along the main frame 1.

[0039] On the other hand, a wear-resistant part 101 is provided on the end face of the drive component 2 that abuts against the power transmission rod 3. The wear-resistant part 101 is made of Teflon. When the user presses the drive component 2 and moves it along the main frame 1, the power transmission rod 3 will be in a state of mutual friction with the drive component 2. The wear-resistant part 101 helps to reduce the resistance between the drive component 2 and the power transmission rod 3, and reduces the probability of the drive component 2 and / or the power transmission rod 3 wearing out too quickly due to excessive friction.

[0040] Correspondingly, the main frame 1 is symmetrically equipped with two sets of return springs 6 along its length, with the centerline as the axis of symmetry. The fixed ends of the two sets of return springs 6 abut against the main frame 1, and the free ends of the two sets of return springs 6 abut against the two ends of the driving component 2 along its length. The two sets of return springs 6 are used to drive the driving component 2 to reset along the main frame 1. The fixed ends of the two sets of return springs 6 are fixed to the surface of the main frame 11 facing the bottom cover 12 to reduce the probability of the two sets of return springs 6 becoming loose or falling off along the main frame 11. The mechanical structure is simple and highly stable, reducing the probability of the driving component 2 failing to reset quickly when it moves, thus affecting the user experience.

[0041] Reference Figure 2 and Figure 3 The power transmission rod 3 has an integrally formed rotating shaft 7 in the middle section along its length, and the rotating shaft 7 is rotatably connected to the main frame 1.

[0042] Specifically, the rotating shaft 7 is formed by extending outwards and in the opposite direction from both sides of the power transmission rod 3 along the thickness direction, without the need for additional assembly of the rotating shaft 7 and the power transmission rod 3, thereby improving the stability of the cooperation between the rotating shaft 7 and the power transmission rod 3.

[0043] The rotational connection between the power transmission rod 3 and the main frame 1 is achieved by the integrally molded rotating shaft 7, which helps to reduce the resistance that the power transmission rod 3 bears when it moves along the main frame 11 and improves the stability of the power transmission rod 3 when it moves along the main frame 11.

[0044] Reference Figure 2 and Figure 3 The main frame 1 has a guide groove 8, and the unlocking rod 4 slides and engages with the guide groove 8.

[0045] The guide groove 8 is located on the inner wall of the main frame 11 facing the bottom cover 12. The width of the guide groove 8 and the width tolerance of the unlocking rod 4 are in a transition fit. Since the unlocking rod 4 is connected to the telescopic mechanism, the limiting and guiding effect of the guide groove 8 improves the stability of the unlocking rod 4 sliding along the main frame 1, so that the unlocking rod 4 can slide smoothly along the main frame 1.

[0046] Meanwhile, a limiting cover 9 is provided on the guide groove 8. Each side of the limiting cover 9 along its width direction has a buckle 91, which engages with the guide groove 8. The buckles 91 and the limiting cover 9 are integrally formed to improve the stability of their engagement. Additionally, each side of the guide groove 8 along its width direction has a locking groove 102, which engages with the buckles 91, thus ensuring the limiting cover 9 is stably fixed to the guide groove 8.

[0047] Therefore, the limiting cover 9 protects the unlocking rod 4 located in the guide groove 8, reducing the probability that the unlocking rod 4 will fall off the guide groove 8 due to excessive force when sliding along the guide groove 8. The limiting cover 9 is fastened to the guide groove 8 by the buckle 91, which improves the convenience of installing the limiting cover 9 in the guide groove 8. The mechanical structure is simple and has high stability.

[0048] In addition, a soft pad 10 is provided on the main frame 1 located on one side of the limiting groove 5; wherein, the soft pad 10 is located on the outside of the bottom cover 12, and the soft pad 10 can be a plastic soft pad 10. In this embodiment, preferably, the soft pad 10 is made of silicone material to improve the user's grip experience.

[0049] The implementation principle of a novel luggage handle structure in this application embodiment is as follows: Since the driving component 2 is movably connected to the main frame 1, when the user applies force to the driving component 2, the driving component 2 will move along the main frame 1. When the driving component 2 moves, it will drive the power transmission rod 3, which abuts against the driving component 2, to rotate along the main frame 1. When the power transmission rod 3 rotates along the main frame 1, it will also drive the unlocking rod 4 to move along the main frame 1, thereby realizing the action of the telescopic mechanism connected to the unlocking rod 4, and achieving the purpose of unlocking the telescopic mechanism. The simple mechanical structure plays a positive guiding role in improving the convenience of unlocking the telescopic mechanism.

[0050] 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.
