Description

Technical Field

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

[0002] Electric suitcases are innovative travel products that combine the functions of traditional suitcases with electric mobility. However, their design is constantly constrained by stringent industry regulations regarding their external dimensions. For example, the International Air Transport Association (IATA) stipulates that the sum of the three sides of carry-on baggage must not exceed 115 centimeters, and railway departments also have clear size restrictions on board luggage. These strict standards significantly limit the expandable space of suitcases. Against this backdrop, maximizing internal storage capacity within limited external dimensions has become a core focus for major suitcase brands to enhance product competitiveness. Industry research and practical verification have shown that optimizing and reducing the size of the suitcase's telescopic structure can effectively free up internal storage space.

[0003] For example, Chinese patent document CN118948023A discloses a folding frame, a suitcase, and a trolley, including a folding frame body. The folding frame body includes a back panel, a connecting beam, and a handrail. One end of the connecting beam is hinged to the side wall of the back panel, and the other end of the connecting beam is horizontally hinged to a wheel frame with electric wheels mounted on it. This patent's folding frame body has two states: folded and unfolded. The folding frame body can be used in conjunction with either the suitcase body or the trolley body. When the folding frame body is folded, the suitcase body or the trolley body can be used as a suitcase or a trolley, respectively. When the folding frame body is unfolded, it can be used as a scooter in conjunction with either the suitcase body or the trolley body. The folding frame body used in the above patent is embedded within the suitcase body, changing the traditional horizontally positioned electric push rod structure and thus increasing the internal storage cavity. However, compared with the cylindrical structure of the electric actuator, the plate-shaped structure of the folding frame generally provides less support. In addition, the electric actuator is located in the middle of the folding frame, resulting in uneven force distribution. When the load is too heavy, the telescopic rod of the electric actuator is prone to deformation, affecting the stability of the support.

[0004] Therefore, it is necessary for those skilled in the art to provide an electric suitcase, optimize the telescopic structure of the suitcase, improve the internal storage space, and ensure the supporting effect of the telescopic structure. Utility Model Content

[0005] The purpose of this application is to provide an electric suitcase to solve the technical problems of small internal storage capacity and uneven force on the electric push rod of electric suitcases with folding racks in the prior art.

[0006] The technical solution adopted by this application to solve its technical problem is: an electric suitcase, including a suitcase body, a steering rod that can be extended and retracted on the suitcase body, and a telescopic part for controlling the extension and retraction of the steering rod relative to the suitcase body. One end of the telescopic part is disposed on the suitcase body, and the other end of the telescopic part is rotatably disposed on the steering rod. The telescopic part includes a push rod motor and a folding plate. One end of the push rod motor is disposed on the top of the suitcase body, and the other end of the push rod motor faces the bottom of the suitcase body. The end of the folding plate away from the push rod motor is rotatably disposed on the steering rod. The end of the folding plate near the push rod motor is rotatably connected to the telescopic rod of the push rod motor. The push rod motor and the folding plate are alternately arranged.

[0007] Furthermore, a connecting block is provided between the folding plate and the push rod motor. The connecting block protrudes towards the push rod motor, one end of the connecting block is fixedly mounted on the folding plate, and the other end of the connecting block is rotatably mounted on the end of the push rod motor.

[0008] Furthermore, the box body is provided with a receiving groove, the telescopic part is located in the receiving groove, and the box body is provided with a partition plate located in the receiving groove.

[0009] Furthermore, the partition plate includes a receiving portion and a sliding portion. The receiving portion is directly opposite the drive wheel on the steering rod, and the sliding portion can accommodate a folding plate. The end of the folding plate is slidably disposed within the sliding portion.

[0010] Furthermore, the end of the folding plate is provided with a roller, and a sliding groove is vertically opened in the receiving part, and the roller is slidably disposed in the sliding groove.

[0011] Furthermore, the steering rod has a protruding mating part, the folding plate is rotatably mounted on the mating part, the folding plate has a groove at one end near the steering rod, the groove has a limiting protrusion on the side near the steering rod, a first limiting block is rotatably mounted in the groove, and a second limiting block is rotatably mounted on the steering rod. The first limiting block and the second limiting block are hinged to each other, and the first limiting block and the second limiting block can abut against the limiting protrusion.

[0012] Furthermore, both the first limiting block and the second limiting block are L-shaped, and the limiting protrusion is located between the first limiting block and the second limiting block. In the riding state, one end of the first limiting block and the second limiting block are hinged to each other and set horizontally. The first limiting block and the second limiting block abut against the upper surface of the limiting protrusion. In the retracted state, there is a gap between the first limiting block and the second limiting block and the upper surface of the limiting protrusion.

[0013] Furthermore, a support portion is provided on the mating part of the steering rod facing the direction of the folding plate. The support portion is located below the folding plate and extends to the limiting protrusion. The support portion can abut against the lower plane of the folding plate.

[0014] The beneficial effects of this application are as follows: This application uses a vertically positioned push rod motor to control the folding plate to switch between a vertical and horizontal state, thereby enabling the electric luggage case to switch between a retracted state and a riding state. The vertically positioned push rod motor effectively ensures the stability of use. Most of the force exerted by the folding plate on the push rod motor is distributed along the axial direction of the motor, effectively reducing the radial force on the motor, preventing bending, and improving the uniformity of force distribution. Simultaneously, the vertically positioned push rod motor reduces the space occupied by the internal storage cavity of the case, improving space utilization. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1 , Figure 6 This application provides an electric suitcase, including a suitcase body 10, a steering rod 30 that can be extended and retracted on the suitcase body 10, and a telescopic part 20 for controlling the extension and retraction of the steering rod 30 relative to the suitcase body 10.

[0030] When in use, the electric luggage compartment is in the retracted state (see...). Figure 1 The telescopic part 20 is controlled by a switch or mobile app, causing the steering rod 30 to extend forward relative to the box body 10, thereby putting the electric luggage box into a riding state (see...). Figure 6 ).

[0031] Further, please see Figures 2-5 , Figure 7 , Figure 8 The box body 10 is provided with a receiving groove 11. In the retracted state, the telescopic part 20 is located in the receiving groove 11. The box body 10 is provided with a partition plate 12 located in the receiving groove 11. One end of the telescopic part 20 is provided on the box body 10, and the other end of the telescopic part 20 is rotatably provided on the steering rod 30.

[0032] Specifically, the telescopic part 20 includes a push rod motor 21 and a folding plate 22. One end of the push rod motor 21 is located at the top of the housing 10, and the other end of the push rod motor 21 faces the bottom of the housing 10. The end of the folding plate 22 away from the push rod motor 21 is rotatably mounted on the steering rod 30, and the end of the folding plate 22 near the push rod motor 21 is rotatably connected to the telescopic rod of the push rod motor 21. The end of the folding plate 22 near the push rod motor 21 is slidably mounted inside the housing 10 under the drive of the push rod motor 21.

[0033] The push rod motor 21 and the folding plate 22 are staggered, and a connecting block 23 is provided between the folding plate 22 and the push rod motor 21. The connecting block 23 protrudes towards the push rod motor 21 and is rotatably connected to one end of the push rod motor 21. Thus, when the push rod motor 21 is working, its telescopic rod pushes against the connecting block 23. Because the connecting block 23 protrudes from the folding plate 22, the telescopic rod of the push rod motor 21 applies a pushing force to one side of the folding plate 22. The end of the folding plate 22 away from the push rod motor 21 can slide back and forth within the housing 10 under the drive of the push rod motor 21, thereby enabling the switching of the folding plate 22 between a vertical and horizontal state, that is, switching between the retracted state and the riding state of the electric luggage box.

[0034] In this embodiment, the connecting block 23 is L-shaped. One end of the connecting block 23 is fixedly mounted on the folding plate 22, and the other end of the connecting block 23 is rotatably mounted on the end of the push rod motor 21. In the retracted state (see attached diagram), Figure 3 The L-shaped connecting block 23 ensures that the force applied by the telescopic rod of the push rod motor 21 acts perpendicularly on the connecting block 23. The thrust generated by the connecting block 23 after being subjected to force acts on one side of the folding plate 22, thus achieving the pushing of the folding plate 22 and ensuring maximum efficiency in force transmission, improving the performance of the push rod motor 21. (In riding mode (participating...)) Figure 11 The folding plate 22 and the push rod motor 21 are still connected by an L-shaped connecting block 23. This L-shaped connecting block 23 creates a gap between the circumferential side of the push rod motor 21's telescopic rod and the end face of the folding plate 22. In use, when the upper surface of the folding plate 22 is bearing load or when the folding plate 22 is compressed, the force on the folding plate 22 cannot directly act on the circumferential surface of the push rod motor 21, thus reducing the radial force impact on the push rod motor 21. When the folding plate 22 is under load, the pressure is first transmitted to the connecting block 23, and then transmitted and concentrated to the end of the push rod motor 21. The pressure from the folding plate 22 on the push rod motor 21 is distributed along the axial direction of the push rod motor 21, ensuring uniform force distribution and operational stability, preventing excessive bending of the push rod motor 21's telescopic rod, and ensuring its service life.

[0035] In use, the push rod motor 21 is activated, the connecting block 23 is subjected to pressure and pushes against the folding plate 22, the folding plate 22 moves from a vertical state to a horizontal state, thus pushing against the steering rod 30, thereby switching the electric luggage box from the retracted state to the riding state. Activating the push rod motor 21 again, the connecting block 23 is subjected to tension and pulls the folding plate 22, the folding plate 22 moves from a horizontal state to a vertical state, thus retracting the steering rod 30, and switching the electric luggage box from the riding state to the retracted state.

[0036] When the electric luggage box described in this application switches between riding mode and retracted mode, the telescopic rod of the push rod motor 21 moves up and down to bear gravity. One end of the folding plate 22 rotates around the end of the telescopic rod of the push rod motor 21, while the other end of the folding plate 22 is rotatably mounted on the steering rod 30. This allows one end of the folding plate 22 to move up and down, and the other end to move back and forth, achieving a quick and stable switch between usage modes. The telescopic part 20 of this application mainly consists of only a push rod motor 21 and a folding plate 22. Compared with the complex telescopic structures in the prior art, this application only uses the simple structure of stretching and pushing the folding plate 22 to control the extension and retraction of the steering rod 30, greatly reducing the occupation of the internal storage cavity of the box body 10 and reducing the overall weight of the electric luggage box. At the same time, the simplified telescopic part 20 greatly facilitates daily cleaning and maintenance, and has broad application prospects.

[0037] This application uses a vertically positioned push rod motor 21 to control the folding plate 22 to switch between a vertical and a horizontal state, thereby enabling the electric luggage case to switch between a retracted state and a riding state. The vertically positioned push rod motor 21 effectively ensures the stability of use. Most of the force exerted by the folding plate 22 on the push rod motor 21 is distributed along the axial direction of the push rod motor 21, effectively reducing the radial force on the push rod motor 21 and preventing it from bending. At the same time, the vertically positioned push rod motor 21 reduces the occupation of the internal storage cavity of the case 10, further increasing the storage space.

[0038] Understandably, one end of the push rod motor 21 described in this application is located at the top of the housing 10, and the other end of the push rod motor 21 faces the bottom of the housing 10. When the push rod motor 21 is vertically installed inside the housing 10, the volume of the telescopic part 20 is minimized, which can reduce the occupation of the internal storage space of the housing 10 to the greatest extent. When the push rod motor 21 is inclined inside the housing 10, the telescopic rod of the push rod motor 21 can better push against the folding plate 22, improving the stability of the push.

[0039] In this embodiment, the push rod motor 21 is rotatably connected to the top of the housing 10. When the push rod motor 21 pushes against the folding plate 22, the connecting block 23 has a certain range of rotation. By offsetting the push rod motor 21 at a small angle, the radial thrust applied by the connecting block 23 to the push rod motor 21 is buffered to ensure stability in use.

[0040] In other embodiments, the push rod motor 21 is fixedly connected to the top of the housing 10, and the connecting block 23 is deformable. When the push rod motor 21 pushes against the folding plate 22, the connecting block 23 undergoes slight deformation to prevent the connecting block 23 from pushing against the push rod motor 21 radially, and to prevent the extension rod of the push rod motor 21 from being subjected to force in the circumferential direction, thus ensuring stability in use.

[0041] Please see Figures 8-11 The partition plate 12 includes a receiving portion 121 and a sliding portion 122. The receiving portion 121 is directly opposite to the drive wheel on the steering rod 30 and is used to receive the drive wheel. The sliding portion 122 can receive the folding plate 22, and the end of the folding plate 22 is slidably disposed in the sliding portion 122.

[0042] Specifically, please refer to Figure 3 , Figure 11 , Figure 12 The folding plate 22 is equipped with rollers 24 at both ends, and a sliding groove 123 is vertically formed in the receiving part 121. The rollers 24 are slidably disposed in the sliding groove 123. In use, the two ends of the folding plate 22 slide along the extension direction of the sliding groove 123 using the rollers 24, thereby controlling the switching between the vertical and horizontal states of the folding plate 22. At the same time, the rollers 24 disposed in the sliding groove 123 can restrict the movement path of the folding plate 22, so that when the push rod motor 21 pushes and pulls the folding plate 22, it only needs to drive it to move up and down without deviation, preventing radial force on the push rod motor 21, preventing bending, and improving the stability of use.

[0043] In this embodiment, the partition plate 12 is also provided with an avoidance groove (not shown in the figure) to accommodate the extension and retraction of the push rod motor 21, further reducing the volume of the extension part 20 and increasing the size of the storage cavity inside the box 10.

[0044] In this embodiment, the steering rod 30 is provided with a mating part 31. The folding plate 22 is rotatably mounted on the mating part 31 using connectors such as pins and shafts. The folding plate 22 is provided with a groove 26 at one end near the steering rod 30. The groove 26 is provided with a limiting protrusion 28 on the side near the steering rod 30. A first limiting block 25 is rotatably provided in the groove 26. A second limiting block 27 is rotatably provided on the steering rod 30. The first limiting block 25 and the second limiting block 27 are hinged to each other. The first limiting block 25 and the second limiting block 27 can abut against the limiting protrusion 28.

[0045] Furthermore, both the first limiting block 25 and the second limiting block 27 are L-shaped, and the limiting protrusion 28 is located between the first limiting block 25 and the second limiting block 27. In the riding state, one end of the first limiting block 25 and the second limiting block 27 are hinged together and horizontally positioned, while the first limiting block 25 and the second limiting block 27 abut against the upper surface of the limiting protrusion 28 (see...). Figure 12Thus, when the folding plate 22 rotates to the predetermined position relative to the mating part 31, the first limiting block 25 and the second limiting block 27 simultaneously abut against the upper surface of the limiting protrusion 28, preventing the folding plate 22 from rotating further and thus limiting the rotation of the folding plate 22, ensuring the stability of the folding plate 22 in the riding state. When the electric luggage box retracts from the riding state to the retracted state, the folding plate 22 rotates in the opposite direction. At this time, the first limiting block 25 and the second limiting block 27 rotate relative to each other and reset (see...). Figure 3 The first limiting block 25 and the second limiting block 27 leave a gap between the upper surface of the limiting protrusion 28, thereby completing the rotation and retraction of the folding plate 22, which facilitates the rotation and unfolding of the folding plate 22 next time, thus ensuring the stability of use.

[0046] Furthermore, a support portion 32 protrudes from the mating portion 31 on the steering rod 30 toward the folding plate 22. The support portion 32 is located below the folding plate 22 and extends to the limiting protrusion 28. The support portion 32 can abut against the lower plane of the folding plate 22. In the riding state, the lower plane of the folding plate 22 abuts against the upper plane of the support portion 32, thereby supporting the folding plate 22. The first limiting block 25 and the second limiting block 27 located above the folding plate 22 provide flipping limits, and the support portion 32 located below the folding plate 22 provides support limits, thus ensuring the stability and safety of the folding plate 22 in the riding state.

[0047] The specific operation method of this application is as follows: When the push rod motor 21 is started, the connecting block 23 is subjected to pressure and pushes against the folding plate 22. The folding plate 22 moves from a vertical state to a horizontal state, thereby pushing against the steering rod 30 and switching the electric luggage box from the retracted state to the riding state. When the push rod motor 21 is started again, the connecting block 23 is subjected to tension and pulls the folding plate 22. The folding plate 22 moves from a horizontal state to a vertical state, thereby retracting the steering rod 30 and switching the electric luggage box from the riding state to the retracted state.

[0048] This application uses a vertically positioned push rod motor 21 to control the folding plate 22 to switch between a vertical and a horizontal state, thereby enabling the electric luggage case to switch between a retracted state and a riding state. The vertically positioned push rod motor 21 effectively ensures stability during use. Most of the force exerted by the folding plate 22 on the push rod motor 21 is distributed along the axial direction of the push rod motor 21, effectively reducing radial force on the push rod motor 21, preventing bending, and improving the uniformity of force distribution. Simultaneously, the vertically positioned push rod motor 21 reduces the space occupied by the internal storage cavity of the case 10, improving space utilization.

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.
