Description

Technical Field

[0001] The utility model relates to a multifunctional electric pull rod structure. Background Art

[0002] With the increasing application of modern electric equipment in various fields, electric pull rods, as a common power transmission device, have been widely used in various devices, especially in transportation vehicles such as electric luggage, electric scooters, and electric carts. The main function of electric pull rods is to provide convenient telescopic adjustment and traction capabilities through power drive to adapt to different usage needs and scenarios. However, the existing electric pull rod structure has multiple technical defects in its design and use, affecting its performance stability and applicability.

[0003] First, the connection of the electric pull rod structure is not stable, especially the connection between the power rod and the driven component. In traditional designs, the connection between the power rod and the driven component usually relies on a simple plug-in or slot-type method, lacking sufficient fastening measures. During long-term use, vibration, load changes, or external forces can easily cause the connection to loosen or fall off, affecting the service life and safety of the equipment.

[0004] Secondly, existing electric pull rods are complex to assemble, and some designs lack sufficient simplicity and precision in their connection methods. The installation process often requires the coordination of multiple components, and disassembly and adjustment are inconvenient, resulting in low production efficiency and increased difficulty in maintenance and repair. This inconvenient assembly method not only increases manufacturing and maintenance costs but also negatively impacts the user experience.

[0005] Furthermore, existing electric pull rods often lack effective power transmission efficiency and power system stability. The connection between the power wheel and the battery box is often not tightly designed, or the power supply is insufficient. This results in the system being unable to continuously provide sufficient driving force during operation. This is especially prone to power shortages and transmission problems under high loads or frequent use.

[0006] In terms of structural adjustability, existing electric trolley designs use a relatively simple telescopic connection between the vehicle body and front rods, failing to fully consider the flexibility required for diverse applications and user needs. This limits the product's adaptability, making it incapable of handling more complex usage scenarios and hindering its versatility. Utility Model Content

[0036] Example 1

[0037] See Figure 1-3 As shown, a multifunctional electric pull rod structure includes a power rod body 1 and a driven component 2 arranged behind the power rod body 1. The power rod body 1 includes:

[0038] A headstock 11, on which a battery box 12 is mounted;

[0039] A body rod 13 is telescopically connected to the front seat 11, and a front rod 14 is provided on the body rod 13 and is telescopically connected to the body rod 13. The front rod 14 is a telescopic rod and is provided with an electronic display 141, a front headlight 142 and a control button 143 for controlling forward and reverse movement;

[0040] The bottom of the headstock 11 is provided with a power wheel 15 driven by a power source provided by a battery box 12;

[0041] The headstock 11 is provided with an installation position 16, and a fixing hole 17 is screwed into the installation position 16;

[0042] The driven component 2 is provided with a mounting clamp, which forms a clamp with the power rod body 1 and abuts against the mounting clamp position 16;

[0043] The mounting clamp is provided with a connection hole 22 that matches the fixing hole 17;

[0044] The headstock 11 further includes screws that can sequentially penetrate the connecting hole 22 and the fixing hole 17 .

[0045] This design uses a telescopic connection between the headstock 11, the body rod 13, and the headstock 14 to adjust the length of the pull rod according to usage requirements. The body rod 13 is a telescopic rod. This structure makes the electric pull rod highly adaptable in different application scenarios, able to meet the needs of different lengths and heights, and improves the versatility of the product. A power wheel body 15 is set at the bottom of the headstock 11, and the battery box 12 provides a power source. This design gives the pull rod a driving force and can automatically move forward or adjust its position. This electric drive method reduces manpower consumption and makes operation easier, making it suitable for scenarios that require long-term work or towing.

[0046] The design of the mounting bracket 16 on the headstock 11, the fitting of the mounting clamp and the fixing holes 17, provides a stable fixing mechanism. The combination of the clamp and the bracket forms a tight clamping structure, ensuring the firmness and stability of the tie rod structure, preventing loosening or falling off during use and increasing the safety of the equipment. The design of the connecting holes 22 and screws that cooperate with the mounting clamp and the fixing holes 17 facilitates the installation and removal of the tie rod structure. The screw connection simplifies and expedited the assembly and disassembly process, reducing the workload during maintenance and component replacement, and improving the maintainability of the equipment.

[0047] The battery box 12 is integrated into the headrest 11 to centrally manage the power source, avoiding the bulkiness and inconvenience of external batteries. Through reasonable layout, the design of the battery box 12 helps to improve the endurance of the device, while reducing dependence on external power sources, enhancing the independence and convenience of the device. The battery box can be charged with a dedicated charger or a mobile phone charger interface, which is more convenient. The versatility of the electric pull rod structure, especially the retractable and drivable design, enables it to play a role in multiple scenarios, such as traction, towing, and auxiliary transportation. It can be applied to different industries, such as logistics and transportation, trailer systems, garden management, construction, etc., and has broad application prospects.

[0048] The driven assembly 2 is a pedal assembly, which includes a first connecting clamp 21 fixed with a screw to the headstock 11, an intermediate pedal 23 rotatably connected to the first connecting clamp 21, and a rear wheel pedal 24 rotatably connected to the intermediate pedal 23; a connecting piece 231 is provided at the front of the intermediate pedal 23, a kickstand 232 is provided on one side of the intermediate pedal 23, and a connecting clamp 233 is provided at the rear of the intermediate pedal 23.

[0049] The first connecting clamp 21 is fixed to the headstock 11 by screws, ensuring that the pedal assembly is stable and reliable during use, avoiding loosening or falling off, and improving the stability and safety of the overall structure; the rotating connection design between the intermediate pedal 23 and the first connecting clamp 21 allows the pedal to flexibly adjust the angle according to usage requirements, adapt to different operating methods and user comfort, and enhance the ergonomic design.

[0050] The kickstand 232 provided on one side of the middle pedal 23 can provide additional support for the user, improve comfort and stability, especially when continuous standing or pedaling is required during use, reducing the burden on the feet; through the design of the connecting piece 231 and the card position, the installation and disassembly of the pedal assembly becomes easier, which is convenient for users to adjust or replace the pedals as needed, thereby improving the maintainability of the equipment; the rotational connection between the rear wheel pedal 24 and the middle pedal 23 provides better operational flexibility and comfort, allowing users to adjust the position of the pedals as needed, further improving the overall use experience.

[0051] The first connecting clamp 21 is provided with a connecting groove 211 for the connecting piece 231 to be inserted and rotated, and the first rotating hole position that passes through the connecting groove 211 is provided at the positions corresponding to the connecting groove 211 on both sides of the first connecting clamp 21, and the connecting piece 231 is provided with a second rotating hole position that matches the first rotating hole position, and a rotating shaft is inserted into the first rotating hole position and the second rotating hole position; the connecting clamp position 233 includes a slide groove and a third rotating hole position arranged on one side of the slide groove, and the rear wheel pedal 24 is provided with a rotating clamp 241 that is clamped into the first slide groove, and the rotating clamp 241 is provided with a fourth rotating hole position that matches the third rotating hole position, and a rotating shaft is inserted into the third rotating hole position and the fourth rotating hole position.

[0052] The rotational connection between the connecting slot 211 and the connecting piece 231 on the first connecting clamp 21, combined with the design of the rotating shaft, allows for smoother rotation of the pedal assembly with a certain degree of freedom. This structure ensures smooth pedal rotation during use, enhancing operational flexibility and comfort. The first and second rotation holes mate well with each other, and the insertion of the rotating shaft effectively secures the rotational connection between the intermediate pedal 23 and the first connecting clamp 21, making the rotation between the two more stable and less prone to loosening, extending service life and improving safety.

[0053] The design of the sliding groove provided on the connecting latch 233 and the third rotation hole ensures a more secure installation of the rear wheel pedal 24. The rotating clamp 241 cooperates well with the sliding groove, effectively connecting the rear wheel pedal 24 to other components, allowing it to form a rotational clearance after rotation, preventing rotational obstruction. The design of the rotating clamp 241, in conjunction with the third and fourth rotation holes, simplifies the installation and removal of the rear wheel pedal 24. The coordination between the rotating clamp 241, the sliding groove, and the rotation shaft also makes the pedal adjustment process faster, without the need for complex tools or operation.

[0054] Inserting the rotating shaft between the first rotating hole position, the second rotating hole position, the third rotating hole position and the fourth rotating hole position reduces wear caused by direct contact and enhances the wear resistance of the component, especially in an environment of frequent use, which can effectively reduce the loss of components and extend their service life.

[0055] Example 2

[0056] See Figure 4-5 As shown, a multifunctional electric pull rod structure includes a power rod body 1 and a driven component 2 arranged behind the power rod body 1. The power rod body 1 includes:

[0057] A headstock 11, on which a battery box 12 is mounted;

[0058] A body rod 13 is telescopically connected to the front seat 11, and a front rod 14 is provided on the body rod 13 and is telescopically connected to the body rod 13. The front rod 14 is a telescopic rod and is provided with an electronic display 141, a front headlight 142 and a control button 143 for controlling forward and reverse movement;

[0059] The bottom of the headstock 11 is provided with a power wheel 15 driven by a power source provided by a battery box 12;

[0060] The headstock 11 is provided with an installation position 16, and a fixing hole 17 is screwed into the installation position 16;

[0061] The driven component 2 is provided with a mounting clamp, which forms a clamp with the power rod body 1 and abuts against the mounting clamp position 16;

[0062] The mounting clamp is provided with a connection hole 22 that matches the fixing hole 17;

[0063] The headstock 11 further includes screws that can sequentially penetrate the connecting hole 22 and the fixing hole 17 .

[0064] The driven component 2 is a trunk body 27 component, which includes a second connecting clamp 25 fixed with the headstock 11 by screws, a telescopic plate portion 26 fixedly connected to the second connecting clamp 25, a trunk body 27 connected to the telescopic plate portion 26, and a trunk rear wheel 28 arranged below the trunk body 27.

[0065] The second connecting clamp 25 is fixed to the vehicle headrest 11 with screws, ensuring that the luggage body 27 assembly is secure and stable during use, preventing it from loosening or falling off, thereby enhancing the safety and reliability of the entire luggage body 27. The fixed connection between the telescopic plate 26 and the second connecting clamp 25 allows the luggage body 27 assembly to be adjusted in length or height as needed. This telescopic design provides greater adaptability, for example, by adjusting the position of the luggage body 27 according to different loads, making it easier for users to operate.

[0066] The design of the connection between the retractable plate 26 and the luggage body 27 allows for greater flexibility in the volume and load capacity of the luggage body 27. The length of the retractable plate can be adjusted to optimize space usage and facilitate carrying more items, depending on usage needs. The rear wheels located underneath the luggage body 27 ensure greater stability when pushing and pulling, allowing users to easily maneuver the luggage body 27, especially during long-distance transport or on uneven surfaces, ensuring good stability.

[0067] The design of the entire luggage case body 27 assembly makes it easier to connect and disassemble the luggage case body 27. The fixed connection between the telescopic plate 26 and the luggage case body 27 also makes it convenient for users to adjust and install according to actual needs, thereby enhancing the convenience and user experience of the product. The connection design between the telescopic plate 26 and the luggage case body 27 can effectively share the load, reduce uneven force, and help extend the service life, especially in an environment of frequent movement and use, which can greatly improve the durability of the luggage case body 27.

[0068] Footrests 251 are provided on both sides of the second connecting clamp 25, and a curved plate body 252 is provided between the second connecting clamp 25 and the telescopic plate portion 26. One end of the curved plate body 252 is integrally formed with the second connecting clamp 25, and the other end is integrally formed with the telescopic plate portion 26. There is a horizontal position difference between the second connecting clamp 25 and the telescopic plate portion 26; the bottom of the suitcase body 27 is provided with an accommodating space for accommodating the retractable plate portion 26, and the front of the accommodating space is also provided with a curved groove portion for accommodating the retraction of the curved plate body 252.

[0069] The second connecting clamp 25 is provided with footrests 251 on both sides, which users can use to place their feet while riding, providing greater operational stability. The curved plate 252 is integrally formed with the second connecting clamp 25 at one end and with the telescopic plate 26 at the other end. This design provides a more flexible connection method, allowing the telescopic plate 26 to connect smoothly with the second connecting clamp 25 and maintain a horizontal position difference. Through this structure, the telescopic plate can be adjusted more smoothly, avoiding the inconvenience caused by uneven extension and retraction. The horizontal position difference design between the second connecting clamp 25 and the telescopic plate 26 enables the telescopic plate to maintain relatively smooth and stable movement during extension and retraction, avoiding unnecessary twisting or shaking.

[0070] The bottom of the luggage case body 27 features a dedicated space for retracting the retractable panel 26. This effectively stores the retractable panel 26, preventing it from being exposed, and enhancing the overall compactness and aesthetics of the luggage case body 27. This design enhances the appearance of the luggage case body 27 and eliminates the need for additional space when not in use. A curved groove is provided at the front of this space to accommodate the retracted curved panel 252. This design allows the curved panel 252 to be more compactly stored within the luggage case body 27 when retracted, preventing potential exposure or clutter. It also protects the curved panel 252 from damage or wear due to excessive exposure.

[0071] It should be noted that in the present solution, the retractable plate 26 is retracted by a motor, and the motor is arranged inside the suitcase. It can be started by pressing a button on the suitcase or by remote control via a mobile phone, thereby achieving automatic retraction and extension without manual retraction.

[0072] The curved plate 252 not only connects the telescopic plate 26 and the second connecting clamp 25 but also improves the overall stability of the luggage case body 27 through load sharing through a rational structure. This reduces excessive wear during use and extends the service life of the luggage case body 27. The horizontal difference between the telescopic plate 26 and the second connecting clamp 25 helps balance the forces acting on the various components, reducing damage or loosening due to mechanical imbalance, thereby improving overall stability and durability.

[0073] The design of the accommodating space and the curved groove effectively prevents the retractable plate portion 26 and the curved plate body 252 from being squeezed or damaged when retracted. This carefully designed storage method not only enhances the protection function of the luggage case body 27, but also ensures that the retractable plate and the curved plate body 252 are in good condition during long-term use.

[0074] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
