Description

Technical Field

[0001] This application relates to the field of electric luggage technology, and in particular to an electric luggage with a retractable foot pedal. Background Technology

[0002] Electric suitcases are a new type of travel equipment that integrates electric drive and intelligent technology. They not only meet the storage needs of ordinary suitcases but also have functions such as riding and automatic following. When riding, users usually straddle the top of the suitcase with their feet on the pedals to ensure stability. Currently, electric suitcase pedals are mainly of three types: fixed, electrically retractable, and manually folding. Fixed pedals are usually fixed on the outside of the suitcase or on both sides of the front wheel and are always exposed when not riding. Their protruding structure is prone to bumping into pedestrians or being hit by external objects, posing both safety hazards and easy damage.

[0003] To address the aforementioned technical problems, Chinese patent document CN212139648U discloses an electric suitcase, comprising a suitcase body with foot pedals on both sides. A hydraulic cylinder is located at the top left side of the foot pedal's inner cavity, and a connecting plate is located at the output end of the hydraulic cylinder. The right side of the connecting plate extends through and to the right side of the foot pedal. A sliding rod is located on the left side of the bottom of the connecting plate. A groove adapted to the sliding rod is formed at the bottom of the foot pedal's inner cavity. A spring is provided at the connection point between the right side of the sliding rod and the foot pedal. Support columns are located on both sides of the bottom of the suitcase body. The suitcase of the above patent allows for adjustment of the foot pedal length during use, making it more comfortable for the user and solving the problem of exposed foot pedals.

[0004] However, the aforementioned patents rely on drive mechanisms such as electric lead screws. When the luggage compartment's battery is low or the motor malfunctions, the threaded connection between the lead screw and the foot pedal can easily become self-locking, preventing the foot pedal from retracting properly and temporarily creating an exposed state similar to a fixed foot pedal, still posing a risk of impact. Furthermore, the electric telescopic structure is complex, requiring a large space inside the compartment to install the lead screw and motor, which can reduce storage space; and the lead screw drive is prone to jamming, resulting in high maintenance costs. Once the drive mechanism is damaged, ordinary users will find it difficult to repair it themselves.

[0005] Therefore, it is necessary for those skilled in the art to provide an electric suitcase with a retractable foot pedal, which can retract the foot pedal, reduce the occupation of the internal cavity of the suitcase, and improve the convenience and stability of use. Summary of the Invention

[0006] The purpose of this application is to provide an electric suitcase with a retractable foot pedal, so as to solve the technical problems of existing electric suitcases where the foot pedal is exposed, posing safety hazards and being easily damaged, while also occupying internal cavities and reducing storage capacity.

[0008] Furthermore, the linkage assembly is provided in two symmetrically arranged, and the linkage assembly includes a gear rotatably disposed inside the fixed base, a first sprocket connected to the gear, a second sprocket connected to the rotating shaft, and a chain connecting the first sprocket and the second sprocket.

[0009] Furthermore, the fixed base has a cylindrical structure with openings on both sides. The motor is fixedly connected to the fixed base and the output shaft of the motor extends into the interior of the fixed base. The output shaft of the motor is fixedly connected to the gear, and the gears in the two linkage components mesh with each other inside the fixed base.

[0010] Furthermore, the motor can be connected to any one of the gears, and the output shaft of the motor, the two gears, and the two first sprockets are all located in the fixed base.

[0011] Furthermore, the support base includes a first connecting part, a second connecting part, a first overlapping part, and a second overlapping part. The rotating shaft is sleeved inside the first connecting part and the second connecting part, and the rotating shaft is rotatably disposed on the first connecting part and the second connecting part. The second sprocket is located between the first connecting part and the second connecting part.

[0012] Furthermore, the rotating shaft is placed above the first overlapping portion and the second overlapping portion.

Compared with using a telescopic motor to directly control the extension and retraction of the foot pedal, this application adopts a rotation control method, which greatly reduces the drive stroke and achieves synchronous rotation. At the same time, the structure of this application occupies less volume in the internal storage cavity of the box, with most of the structure integrated in the base. Furthermore, the chain-based drive component structure is more stable and reliable, with a longer service life and higher fault tolerance. Attached Figure Description

Detailed Implementation

[0024] The present application will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0025] Please see Figure 1 , Figure 2 This application provides an electric suitcase with a retractable foot pedal. The electric suitcase 10 has a base 20 at its bottom, which is located in a storage cavity (not shown in the figure) inside the electric suitcase 10. The electric suitcase 10 also has placement slots 12 on both sides. The foot pedal 21 is rotatably provided on the base 20. The foot pedal 21 is symmetrically arranged in the placement slots 12 on both sides of the electric suitcase 10, and the foot pedal 21 is rotatably arranged in the placement slots 12.

[0026] In this embodiment, the electric luggage compartment 10 has outer covers 11 on both sides, and the mounting groove 12 is located on the outer cover 11. The outer cover 11 is made of plastic, and the mounting groove 12 is integrally formed with the outer cover 11, improving the ease of processing. The foot pedal 21 extends from the internal storage cavity of the electric luggage compartment 10 to the outside of the electric luggage compartment 10. The outer contour of the foot pedal 21 matches the mounting groove 12, and the foot pedal 21 can be folded into the mounting groove 12. In this way, the foot pedal 21 can be retracted when not in use to prevent damage and improve service life.

[0027] The base 20 is provided with a drive assembly 30, which is used to drive the foot pedal 21 to rotate synchronously at the mounting slot 12.

[0028] Further, please refer to Figures 2-6The drive assembly 30 includes a fixed base 31 fixedly connected to the base 20, a motor 32 mounted on the fixed base 31, and two support bases 33 on both sides of the fixed base 31 located on the base 20. Two support bases 33 are provided, and a rotating shaft 34 is rotatably mounted on each support base 33. The foot pedal 21 is sleeved on the rotating shaft 34. Two linkage components 35 are also provided on both sides of the fixed base 31 and are meshed with each other within the fixed base 31. One linkage component 35 is fixedly connected to the output shaft of the motor 32, and the other end of the linkage component 35 is sleeved on the rotating shaft 34 to drive the rotating shaft 34 to rotate.

[0029] In use, the motor 32 drives one of the linkage components 35 to rotate, which in turn drives the other linkage component 35 to rotate. The rotating shaft 34 connected to the two linkage components 35 rotates synchronously, which in turn drives the two foot pedals 21 to rotate synchronously.

[0030] Specifically, the fixed base 31 has a cylindrical structure with openings on both sides, and the motor 32 is fixedly connected to the fixed base 31 by fasteners such as bolts or screws, and the output shaft of the motor 32 extends into the interior of the fixed base 31.

[0031] Two linkage components 35 are provided and symmetrically arranged. Each linkage component 35 includes a gear 351 rotatably disposed inside the fixed base 31, a first sprocket 352 connected to the gear 351, a second sprocket 353 connected to the rotating shaft 34, and a chain 354 connecting the first sprocket 352 and the second sprocket 353. The output shaft of the motor 32 is fixedly connected to the gear 351, thereby providing power to the gear 351. At the same time, the gears 351 in the two linkage components 35 mesh with each other to achieve synchronous rotation.

[0032] When in use, the starter motor 32 drives the gear 351 to rotate, and the other gear 351 rotates synchronously. At the same time, the first sprocket 352 rotates synchronously and drives the chain 354 and the second sprocket 353 to rotate. The shaft 34 follows the second sprocket 353 to rotate, thereby driving the foot pedal 21 to rotate, thus realizing the synchronous rotation of the two foot pedals 21 on both sides of the electric luggage box 10.

[0033] In this embodiment, since the gears 351 in the two linkage components 35 are directly meshed, when one gear 351 rotates clockwise, the other gear 351 rotates counterclockwise, thereby causing the two foot pedals 21 to rotate synchronously, and at the same time, the rotation directions are exactly opposite, so as to realize the simultaneous contraction and extension of the foot pedals 21.

[0034] In this embodiment, the motor 32 can be connected to any one of the gears 351, increasing the installation range and ensuring operational stability. Meanwhile, the output shaft of the motor 32, the two gears 351, and the two first sprockets 352 are all located within the fixed base 31, thus preventing lubricating oil from splashing out during rotation and reducing maintenance costs.

[0035] Please see Figure 6 The support base 33 includes a first connecting part 331, a second connecting part 332, a first overlapping part 333, and a second overlapping part 334. The rotating shaft 34 is sleeved in the first connecting part 331 and the second connecting part 332. The rotating shaft 34 is rotatably mounted on the first connecting part 331 and the second connecting part 332 using bearings (not shown in the figure). The second sprocket 353 is located between the first connecting part 331 and the second connecting part 332 to ensure rotational stability. At the same time, the rotating shaft 34 is limited by a clamp (not shown in the figure), so that the rotating shaft 34 is axially limited between the first connecting part 331 and the second connecting part 332 to prevent the rotating shaft 34 from moving axially during use, further improving the stability of use and facilitating disassembly and maintenance.

[0036] The rotating shaft 34 is placed above the first overlapping part 333 and the second overlapping part 334. The upper surface of the first overlapping part 333 has a groove (not shown in the figure). The groove matches the diameter of the rotating shaft 34. The rotating shaft 34 overlaps in the groove on the first overlapping part 333, thereby facilitating installation and disassembly.

[0037] A gap is left between the rotating shaft 34 and the second overlapping part 334. Part of the outer cover 11 is located within the gap. The foot pedal 21 is located above the second overlapping part 334 and can press against the upper surface of the second overlapping part 334. The rotating shaft 34 is a double-plane cylindrical rotating shaft, that is, the side of the rotating shaft 34 forms two opposing planes, thereby improving the convenience of installation and reducing rotational resistance. At the same time, the foot pedal 21 has a mounting part 22 that matches the outer contour of the rotating shaft 34. The foot pedal 21 is sleeved on the rotating shaft 34 through the mounting part 22 and fixedly connected to the rotating shaft 34 by fasteners such as bolts or screws.

[0038] The foot pedal 21 has a horizontal state (foot pedal 21 extended) and a vertical state (foot pedal 21 retracted). When the foot pedal 21 is in the horizontal state, the bottom surface of the foot pedal 21 presses against a portion of the outer cover 11, and the portion of the outer cover 11 further presses against the upper surface of the second overlapping part 334. In this way, the second overlapping part 334 is used to support and limit the foot pedal 21, ensuring the stability of the structure when the user steps on it. When the foot pedal 21 is in the vertical state, the mounting part 22 is located in the groove (not shown in the figure) on the upper surface of the second overlapping part 334, thereby realizing the storage of the foot pedal 21 after rotation and preventing interference.

[0039] In use, the second sprocket 353 drives the rotating shaft 34 to rotate, and the foot pedal 21 rotates accordingly, thereby switching the foot pedal 21 between horizontal and vertical states, thus realizing the retraction and extension of the foot pedal 21. The rotating shaft 34, which is in the shape of a double-plane cylinder, improves the stability and accuracy of rotation, reduces the driving stroke, and greatly improves the release speed of the foot pedal 21.

[0040] This application fixes the foot pedal 21 to the rotating shaft 34. By controlling the rotation of the rotating shaft 34, the horizontal and vertical states of the foot pedal 21 can be switched, that is, the extension and retraction of the foot pedal 21 can be controlled, preventing the foot pedal 21 from being exposed when not in use and improving its service life. Compared with using a telescopic motor to directly control the extension and retraction of the foot pedal 21, this application adopts a rotation control method, which greatly reduces the drive stroke and achieves synchronous rotation. At the same time, the structure of this application occupies less volume in the internal storage cavity of the box, with most of the structure integrated in the base 20. Furthermore, the drive assembly 30, mainly based on the chain, is more stable and reliable, with a longer service life and higher fault tolerance.

[0041] It is understood that this application has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, based on the teachings of this application, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this application. Therefore, this application is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this application.
