Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a handle for a trolley case. Background Technology

[0002] The handle of a rolling suitcase, also known as a carrying handle or grip, is an important component of the suitcase, making it easier for users to pull or lift the suitcase. There are several types, including fixed handles, detachable handles, double-bar handles, side handles, and trapezoidal handles. Fixed handles are the most common; they consist of a single, non-detachable retractable metal bar. They are characterized by their simple structure, durability, and long service life.

[0003] Existing technology (Chinese Patent No.: CN104643494A) discloses a rolling suitcase that can simultaneously provide lighting and charging functions during normal use. Even when the power bank is detached from the handle, the suitcase can still be pulled. When the power bank is depleted, it can be recharged and reattached to the handle. Switching the lighting on and off is simple, requiring only a light rotation of the knob, with the handle height precisely at the desired illumination level. Furthermore, the lighting can be adjusted up, down, left, and right as the suitcase is pulled. While its functions are comprehensive, it relies on household electricity to charge its energy storage device, which can lead to power outages in emergencies, causing significant inconvenience to the user. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a suitcase handle that can drive a belt to generate electricity by pulling the handle up and down, thereby charging the energy storage device so that the suitcase or the user's external power device can be used.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A handle for a rolling suitcase, fixedly installed on one side of the suitcase body, includes a mounting box. The mounting box is hollow inside. An energy storage device capable of discharging electricity is fixedly installed at the bottom of the inner cavity of the mounting box. The energy storage device is electrically connected to a belt. The belt is fitted with and drives two power generation components. The two power generation components are fixedly installed on one side wall of the inner cavity of the mounting box. A fixing beam is fixedly connected to the bottom of the belt. Connecting rods are fixedly connected to both ends of the fixing beam. The top of each connecting rod passes through the top surface of the mounting box and is fixedly connected to a handle. A damping component is provided between the two connecting rods and is fixedly connected to one side wall of the inner cavity of the mounting box. One end of the damping component extends out of the mounting box.

[0007] Preferably, the power generation component includes a fixing block, which is fixedly connected to one side wall of the inner cavity of the mounting box. A generator is fixedly connected to one end of the fixing block. The generator is driven by a pulley, which is driven by the belt. The generator is electrically connected to the energy storage device. Two generators are respectively disposed on both sides of the damping component and the fixing beam.

[0008] Preferably, the damping assembly includes a mounting block with a groove on its top surface. Two square rods are slidably connected within the groove, facing each other and detachably connected. Threaded grooves are formed on the facing sides of the two square rods, and each threaded groove is fitted with and screwed onto a frustum-shaped threaded cone. A stud is fixedly connected to one end of each threaded cone, penetrating the sidewall of the groove and screwed onto the mounting block. An extension rod is fixedly connected to one end of the stud, penetrating the sidewall of the mounting box. One end of each square rod abuts against the outer surface of the connecting rod.

[0009] Preferably, the slide is open, and the top of the slide makes sliding contact with two connecting posts. A spring is fixedly connected between the two connecting posts, and the bottom surfaces of the two connecting posts are respectively fixedly connected to the top surfaces of the two square rods.

[0010] Preferably, a rubber pad to increase friction is provided between the two square rods and the connecting rod. One end of the rubber pad is fixedly connected to one end of the square rod, and the other end of the rubber pad is adapted to the outer side of the connecting rod and can be detachably connected.

[0011] Preferably, a mounting groove is provided on one side of the housing, and the mounting groove is adapted to and fixedly connected to the mounting box.

[0012] Compared with the prior art, the present invention has the following advantages and technical effects:

[0013] This invention utilizes a handle fixedly installed on one side of the suitcase to pull out the mounting box, enabling the suitcase to move. Simultaneously, when the handle is pulled out of the mounting box, the generator assembly provides damping to the handle, and the damping assembly further limits its position, facilitating its positioning and fixation at any location after being pulled out of the mounting box. In the retracted state, the damping assembly is not connected to the handle, allowing the handle to drive the belt and charge the energy storage device. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, power supply, and gas supply for driving and / or control. Unless otherwise stated, they are assumed to be used and equipped with existing technology and no special explanation is required.

[0022] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Depend on Figure 1-4 The handle shown is fixedly installed on one side of the suitcase body and includes a mounting box 1. The interior of the mounting box 1 is hollow. An energy storage device 2 capable of discharging electricity is fixedly installed at the bottom of the inner cavity of the mounting box 1. The energy storage device 2 is electrically connected to a belt 3. The belt 3 is fitted with and drives two power generation components. The two power generation components are fixedly installed on one side wall of the inner cavity of the mounting box 1. A pull rod is fixedly connected to the bottom of the belt 3. The pull rod includes a fixed beam 4. The two ends of the fixed beam 4 are respectively fixedly connected to connecting rods 5. The top of the connecting rod 5 passes through the top surface of the mounting box 1 and is fixedly connected to a handle 6. A damping component is provided between the two connecting rods 5. The damping component is fixedly connected to one side wall of the inner cavity of the mounting box 1. One end of the damping component extends out of the mounting box 1.

[0024] Furthermore, the energy storage device 2 can store the electricity generated by the pull rod pulling the belt 3 and thus driving the power generation component, and provide power for the additional electrical components of the suitcase. This is existing technology and will not be described in detail here.

[0025] The scheme is further optimized. The power generation component includes a fixed block 7, which is fixedly connected to one side wall of the inner cavity of the mounting box 1. A generator 8 is fixedly connected to one end of the fixed block 7. The generator 8 is driven by a pulley 9, which is driven by a belt 3. The generator 8 is electrically connected to the energy storage device 2. The two generators 8 are respectively set on both sides of the damping component and the fixed beam 4. The generators 8 are set far apart from each other, which can increase the vertical movement distance of the belt 3, thereby increasing the power generation stroke of the pull rod driving the belt 3 and improving the power generation efficiency of the generator 8.

[0026] Further optimization of the design includes a mounting block 10. A groove 11 is formed on the top surface of the mounting block 10. Two square rods 12 are slidably connected within the groove 11. The two square rods 12 are positioned opposite each other and are detachably connected. The inner cavity of the groove 11 slides against the four contact surfaces of the square rods 12, facilitating the movement of the square rods 12 along the direction of the groove 11, thereby enabling contact with the connecting rod 5. Threaded grooves 13 are formed on the opposite sides of the two square rods 12. Two frustum-shaped threaded cones 14 are fitted and screwed onto the two threaded grooves 13. Rotation of the threaded cones 14 drives the two threaded grooves 13 to move away from each other, thus achieving contact between the square rods 12 and the connecting rod 5. A stud 15 is fixedly connected to one end of the threaded cone 14. The stud 15 penetrates the sidewall of the groove 11 and is screwed onto the mounting block 10. The stud 15 ensures that the axes of the threaded grooves 13 and the threaded cone 14 coincide, preventing the threaded cone 14 from deviating and detaching from the threaded groove 13, which could lead to failure of the damping assembly. An extension rod 16 is fixedly connected to one end of the stud 15. The extension rod 16 passes through the side wall of the mounting box 1, facilitating the user's operation of the threaded taper 14. One end of each of the two square rods 12 abuts against the outer side of the connecting rod 5.

[0027] The scheme is further optimized by opening the slide 11. The top of the slide 11 slides in contact with two connecting posts 17. A spring 18 is fixedly connected between the two connecting posts 17. The bottom surfaces of the two connecting posts 17 are fixedly connected to the top surfaces of the two square rods 12 respectively. The two square rods 12 are indirectly pulled and set to abut against each other through the spring 18, which allows the damping component to flexibly adjust the pull rod according to the actual use.

[0028] In a further optimized design, rubber pads 19 are installed between the two square rods 12 and the connecting rod 5 to increase friction. One end of the rubber pad 19 is fixedly connected to one end of the square rod 12, and the other end of the rubber pad 19 is adapted to the outer side of the connecting rod 5 and can be detachably connected. The rubber pad 19 increases the friction between the connecting rod 5 and the square rod 12, so that when the rubber pad 19 and the connecting rod 5 are in contact, the pull rod cannot be pulled arbitrarily in the mounting box 1, which facilitates the use of the trolley case.

[0029] The design was further optimized by providing an installation groove on one side of the housing, which is compatible with and fixedly connected to the installation box 1.

[0030] The working process of this embodiment is as follows:

[0031] When the rubber pad 19 disengages from the connecting rod 5, the pull rod can be freely pulled within the mounting box 1, facilitating the user's movement of the trolley case. When the user needs to fix the trolley case for support while pulling it, they can manually turn the extension rod 16, causing the stud 15 and threaded taper 14 to rotate, which in turn drives the threaded groove 13 and square rod 12 to move away from each other. Finally, the rubber pad 19 comes into contact with the connecting rod 5, providing frictional restraint to the pull rod and stabilizing its extended state.

[0032] This invention includes an energy storage device 2, which can supply power to external electrical devices (such as mobile phones, tablets, flashlights, etc.), thus improving the practicality of this invention. When the energy storage device 2 is low on power, the user can pull the handle 6 to move the lever up and down, which in turn drives the belt 3 to continuously drive the power generation component to generate electricity, thereby charging the energy storage device 2. This can solve the user's emergency power needs under certain circumstances, increasing the scalability of this invention.

[0033] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
