Description

Technical Field

[0001] This utility model relates to a front-drive sliding plate structure for an electric pull rod. Background Technology

[0002] With the diversification and convenience of people's travel methods, electric suitcases have gradually become popular products in the market. Electric suitcases are usually equipped with an electric lever system for automatically adjusting the extension and retraction of the front end. Most existing electric suitcases use an electric push-rod design, where the front end is pushed out or retracted. However, after long-term use, the electric push-rod may malfunction, causing the front end to fail to extend or retract properly, which can seriously affect the user experience and even damage the product. In addition, the design of an electric push-rod often requires additional mechanical structures and weight, making the overall weight and size of the suitcase relatively bulky, affecting the product's convenience and portability.

[0003] To address the shortcomings of existing electric linkages, the market has begun exploring alternative methods to adjust the front end's extension / retraction function. A common solution is to use an electrically driven front wheel to achieve this. Specifically, the motor on the front wheel drives the vehicle forward or backward, thus propelling the front end's extension / retraction. This design improves the efficiency of front end extension / retraction while also reducing the risk of mechanical failure and weight issues associated with traditional pushrod designs.

[0004] However, some existing front-drive wheel systems still require additional electric push rods or complex mechanical structures, especially when the front end may not be able to precisely control the extension range, or when manual adjustment is not possible in the event of battery problems. Therefore, simplifying the design and improving the user experience while ensuring the product is lightweight and reliable has become the goal of the continuous development of electric luggage technology. Utility Model Content

[0005] The purpose of this utility model is to provide a front drive sliding plate structure with an electric pull rod that achieves a more efficient and convenient front extension function by eliminating the traditional push rod design, adopting a lower guide rail telescopic device and a limiting device, and combining the electric adjustment of the front drive wheel.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A front-drive sliding plate structure with an electric pull rod includes:

[0008] A pair of guide rails, which are located at the bottom of the electric luggage compartment, are used to support the extension and retraction adjustment of the front of the vehicle;

[0009] A telescopic device is installed on the guide rail and connected to the front of the electric luggage compartment. The telescopic device can be manually adjusted to extend or retract the front of the vehicle.

[0010] Limiting devices are installed at both ends of the guide rail to limit the maximum extension and retraction position of the front end during the extension and retraction process;

[0011] The front drive wheel is installed at the front of the electric luggage compartment. The front drive wheel is connected to the front of the vehicle and can be driven by a motor to rotate back and forth.

[0012] A drive unit, connected to the front drive wheels, is used to drive the front drive wheels forward to push the front of the vehicle out when the front of the vehicle needs to be extended, or to reverse and retract the front of the vehicle when the front of the vehicle needs to be retracted.

[0013] A foot pedal, installed at the rear of the electric luggage compartment, is used to restrict the electric luggage compartment during the extension and retraction of the front of the vehicle.

[0014] Preferably, the telescopic device includes multiple sliders that slide along a guide rail, allowing the front of the vehicle to extend or retract forward and backward through manual adjustment.

[0015] Preferably, the limiting device includes a limiting groove, which engages with the guide rail via a buckle to limit the maximum extension position of the vehicle front during the extension and retraction process.

[0016] Preferably, the drive motor of the front drive wheel is connected to the front of the vehicle via a drive shaft, and the rotation of the drive shaft can drive the extension and retraction of the front of the vehicle.

[0017] Preferably, the front drive wheel includes at least one drive wheel, which is controlled by a motor to rotate in the forward or reverse direction, thereby adjusting the extension and retraction of the front of the vehicle.

[0018] Preferably, the electric luggage compartment also includes a control system, which controls the motor drive device according to user input instructions to enable precise extension and retraction of the front of the vehicle.

[0019] Preferably, the drive device for the front drive wheels includes an electric motor, a reduction gear, and a control module. The control module is used to control the starting and reversing of the electric motor and drive the front wheels to extend and retract the front of the vehicle.

[0020] Preferably, the foot pedal device includes a rotating hinge and a return spring disposed within the rotating hinge, and the end of the foot pedal device is curved.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This solution eliminates the traditional electric push-rod system, employing a combination of front drive wheels and a lower guide rail telescopic device, significantly simplifying the structure of the electric luggage compartment. Eliminating the complex components required by the push-rod system reduces the failure rate and maintenance difficulty, thereby improving product reliability and stability. The electric adjustment of the front drive wheels makes the extension and retraction of the front end smoother. When the front end needs to extend, the front drive wheels are driven forward by the motor, quickly and effectively pushing the front end out; when the front end needs to retract, the motor reverses to retract it, simplifying the mechanical operation of traditional push-rod systems.

[0023] Limiting devices are installed at both ends of the guide rail to ensure the maximum extension and retraction position of the locomotive head during the extension and retraction process, preventing the locomotive head from exceeding the preset position due to operational errors or system failures, thereby effectively avoiding damage and unnecessary mechanical burden.

[0024] The telescopic mechanism allows for manual adjustment of the front end, enabling manual adjustment even without power. Furthermore, the electrically adjustable drive system makes the front end extension and retraction more efficient and convenient. Users can choose between manual or electric operation, providing greater flexibility. This solution, through optimized structural design, reduces unnecessary mechanical parts and weight, while improving product stability, convenience, and lifespan, significantly enhancing the market competitiveness of the electric luggage. With consumers increasingly demanding efficient, convenient, and reliable electric luggage, adopting this technology will help companies stand out in the fierce market competition.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example

[0031] See Figure 1-3 As shown, a front-drive sliding plate structure with an electric pull rod includes:

[0032] A pair of guide rails 1, which are set at the bottom of the electric luggage compartment to support the extension and retraction adjustment of the front of the vehicle;

[0033] Telescopic device 2 is installed on the guide rail 1 and connected to the front of the electric luggage compartment. The telescopic device 2 can be manually adjusted to extend and retract the front of the vehicle.

[0034] Limiting devices 3 are installed at both ends of the guide rail 1 to limit the maximum extension and retraction position of the front end during the extension and retraction process;

[0035] The front drive wheel 4 is installed at the front of the electric luggage compartment. The front drive wheel 4 is connected to the front of the vehicle and can be driven by a motor to rotate back and forth.

[0036] Drive unit 5, connected to front drive wheel 4, is used to drive front drive wheel 4 to rotate forward to push the front of the vehicle out when the front of the vehicle needs to be extended, or to reverse to retract the front of the vehicle when the front of the vehicle needs to be retracted.

[0037] Foot pedal 6, installed at the rear of the electric luggage compartment, is used to restrict the electric luggage compartment during the extension and retraction of the front of the vehicle.

[0038] This design simplifies the mechanical structure of the electric luggage by combining the front drive wheel 4 and the telescopic device 2, eliminating the need for a complex push-rod system. This not only reduces the overall weight but also makes the structure more compact and stable, reducing the possibility of malfunctions and improving the reliability of the luggage.

[0039] By combining the motor-driven front drive wheel 4 with the telescopic device 2, users can more conveniently adjust the extension and retraction of the front of the vehicle. This combination of electric control and manual adjustment provides flexibility, allowing users to manually adjust the front of the vehicle when needed, or to adjust it automatically via electric drive, thus enhancing the user experience.

[0040] The design incorporates a limiting device 3 to ensure that the front of the vehicle does not exceed the predetermined position during extension and retraction, thus preventing damage and unnecessary wear. Furthermore, the limiting device 3 ensures the safety of the luggage compartment; even in abnormal situations during use, the front of the vehicle can automatically return to a safe retracted position, preventing uncontrolled extension and retraction.

[0041] The telescopic device 2 includes multiple sliders that slide along the guide rail 1 and allow the front of the vehicle to extend and retract forward and backward by manual adjustment. The limiting device 3 includes a limiting groove that engages with the guide rail 1 via a buckle to limit the maximum extension and retraction position of the front of the vehicle during the extension and retraction process.

[0042] The drive motor of the front drive wheel 4 is connected to the front of the vehicle through a transmission shaft. The rotation of the transmission shaft can drive the extension and retraction of the front of the vehicle. The front drive wheel 4 includes at least one power wheel. The power wheel is controlled by a motor to rotate forward or backward, thereby adjusting the extension and retraction of the front of the vehicle.

[0043] Connecting the motor of the front drive wheel 4 to the front of the vehicle via a driveshaft allows for more efficient power transmission from the motor to the front. The motor controls the forward and reverse rotation of the drive wheel, enabling precise adjustment of the front's extension and retraction, ensuring operational accuracy and flexibility, and enhancing the user experience.

[0044] By employing the coordinated operation of the drive wheels and the electric motor, more efficient energy utilization can be achieved. The forward and reverse rotation control of the electric motor means that the extension and retraction of the vehicle's front end does not rely on excessive mechanical components, reducing mechanical friction and energy waste, thereby improving the overall energy efficiency of the system and extending battery life.

[0045] This solution automatically adjusts the extension and retraction of the vehicle's front end via a motor-driven power wheel, simplifying the manual adjustment process. Users can easily extend and retract the front end with simple controls, greatly improving operational convenience. Furthermore, the precise control of the motor ensures a smoother and more accurate extension and retraction process, reducing uncertainties and errors associated with manual operation and enhancing the system's intelligence.

[0046] The electric luggage compartment also includes a control system, which controls the motor drive device 5 according to user input instructions to enable precise extension and retraction of the front of the vehicle; the drive device 5 of the front drive wheel 4 includes a motor, a reduction gear and a control module, which controls the starting and reversing of the motor to drive the front wheel to extend and retract the front of the vehicle.

[0047] The control system adjusts the electric motor drive unit 5 according to user input commands, enabling precise extension and retraction of the vehicle's front end. Users can flexibly control the extension and retraction range and speed of the front end according to different needs, providing a more customized experience. The control system makes operation more precise, ensuring a smoother and more accurate extension and retraction process for the front end.

[0048] This design combines an electric motor with a reduction gear, effectively regulating the extension and retraction speed of the vehicle's front end and power output. The electric motor provides the necessary power, while the reduction gear ensures smoother power output, avoiding vibrations or instability caused by excessively rapid power transmission, thereby improving the overall system's stability and comfort.

[0049] The control module can automatically adjust the starting and reversing of the electric motor to ensure that the rotation direction of the front drive wheels 4 matches the extension and retraction requirements of the front of the vehicle. This intelligent and automated control method makes it more convenient for users, eliminating the need for manual intervention in complex mechanical operations, greatly improving the user experience of the electric luggage compartment and reducing the risk of human error.

[0050] The foot pedal device 6 includes a rotating hinge 61 and a return spring disposed within the rotating hinge 61. The end of the foot pedal device 6 is curved.

[0051] The rotating hinge 61 design allows the foot pedal to rotate flexibly, enabling adjustment of the foot pedal angle as needed. This hinge rotation enhances the adaptability of the foot pedal, allowing users to easily adjust its position to suit different usage requirements, making operation more comfortable and convenient.

[0052] A return spring located within the rotating hinge 61 ensures that the foot pedal automatically returns to its initial position after use. This reset function prevents the foot pedal from being accidentally placed in an unsuitable position, improves ease of use, ensures the foot pedal is always in the correct position, and reduces damage or malfunction caused by improper placement over a long period.

[0053] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
