Description

Technical Field

[0001] This utility model belongs to the field of electric luggage, and in particular relates to an electric luggage walking assembly. Background Technology

[0002] Electric suitcases are an innovative travel tool that combines traditional suitcases with electric drive technology. They not only have the function of storing luggage, but also realize extended functions such as short-distance transportation and intelligent operation through built-in motors, batteries and control systems, redefining the convenience of modern travel.

[0003] Electric suitcases typically feature a drive assembly consisting of a lever, steering wheels, and drive wheels. The lever has a speed control and a control switch. To use it, you must first turn on the control switch to riding mode, then use the speed control to ride or control the suitcase. When finished riding and switching to push-pull mode, you need to turn off the control switch to disconnect the power to the drive wheels, then retract the lever and pull out the other lever for pushing or pulling. This cumbersome operation of the entire drive assembly results in a relatively poor user experience. Furthermore, the dual-lever operation also takes up interior space. Utility Model Content

[0004] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:

[0005] An electric luggage chassis assembly, comprising:

[0006] Electric wheels and steering wheels are both mounted on the support structure, and the support structure is equipped with a control structure. The control structure is connected to the steering wheel, and a locking structure is independently provided on the outside of the control structure. The control structure and the locking structure are built into the inside of the housing.

[0007] The micro switch corresponds to the locking mechanism and is triggered when the locking mechanism releases the control mechanism.

[0008] When the walking assembly is in use, in riding mode, the steering wheel is controlled by the control structure to control the direction. In push-pull mode, the steering function of the control structure is locked by the locking structure. Each wheel set is installed at the bottom corner (where the structural strength is greatest) on the inner side of the box structure through the support structure. The structure runs stably and the box is not easily deformed.

[0009] In the walking assembly, the support structure includes support frame one and support frame two, which are respectively arranged at the corners of the bottom inner side of the box structure for mounting electric wheels and steering wheels.

[0010] In the walking assembly, a connecting shaft is provided on the steering wheel. The connecting shaft includes a horizontal section, a vertical section, and a connecting section between the two. The horizontal section is offset to one side by 10-60° relative to the vertical section.

[0011] In the walking assembly, a support ring is installed on the vertical section, and a sleeve fitted on the outside of the vertical section and a bearing located between the support frame and the sleeve are provided above the support ring.

[0012] In the walking assembly, the control structure includes a control lever, which is built into the housing structure and exposed at the top with a control handle. The bottom of the control lever is rotatably mounted on a support frame one. A connecting plate one is installed at the bottom of the control lever, a connecting plate two is installed at the top of the vertical section, and a connecting plate three is installed between the connecting plate one and the connecting plate two.

[0013] In the walking assembly, both the horizontal and vertical free sections are provided with external threads, and the connecting plate two is fixed to the top of the vertical section by two sets of nuts.

[0014] In the walking assembly, the locking structure includes a first constraint body and a second constraint body arranged on the outside of the control lever. The first constraint body and the second constraint body are respectively distributed on both sides of the control lever. One end of the first constraint body and the second constraint body are rotatably set, and the other end is independently installed with an elastic element.

[0015] The outer sides of constraint body one and constraint body two are independently equipped with locking bodies, and the position of the locking bodies relative to the control lever is adjustable.

[0016] In the walking assembly, the ends of the first and second constraint bodies that face away from each other and are far from the rotation node are provided with a ramp surface.

[0017] In the walking assembly, a trigger body is provided on the locking body. The trigger body and the micro switch are positioned correspondingly. The micro switch is connected to an independently set power supply and an electric wheel circuit through a circuit.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention ensures forward direction by controlling the steering wheel with a joystick in riding mode. In push-pull mode, a locking mechanism can be used to lock the control structure at an angle, preventing the box structure from tipping over during operation. The locking function and the electric wheel's circuit switch are integrated for convenient operation. Dual-mode operation of the walking assembly can be achieved with a single joystick, significantly improving the user experience and reducing encroachment on the box's interior space. Furthermore, the use of a non-standard connecting shaft allows the steering wheel to be positioned rearward, concealed within the bottom of the box structure, ensuring the support frame is fixed at the inner bottom corner of the box structure (where structural strength is highest).

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1

[0029] like Figures 1 to 4 As shown, an electric luggage chassis assembly includes:

[0030] Electric wheel 10 and steering wheel 20 are both mounted on the support structure, and the support structure is also equipped with a control structure. The control structure is connected to the steering wheel 20. A locking structure is independently provided on the outside of the control structure. The position of the locking structure relative to the control structure is adjustable to adjust the state of the control structure. One state is steering (riding mode), and the other is angle lock state (push-pull mode). The control structure and the locking structure are built into the inside of the housing.

[0031] The micro switch corresponds to the locking mechanism and is triggered when the locking mechanism releases the control mechanism.

[0032] By adjusting the position of the locking mechanism, a micro switch is triggered, which in turn provides power to the electric wheel 10 and releases the control mechanism to switch to steering mode (riding mode).

[0033] Because the box structure 50 needs to have a certain load-bearing strength, it is prone to structural deformation during load-bearing periods, such as... Figure 2 , 3 As shown, the support structure includes a first support frame 30 and a second support frame 40. The first support frame 30 and the second support frame 40 are respectively located at the corners of the bottom inner side of the box structure 50, for mounting the electric wheel 10 and the steering wheel 20. The positions of the first support frame 30 and the second support frame 40 are where the structural strength of the entire box structure 50 is greatest, ensuring structural strength. Simultaneously, the support frames enhance the structural strength of the box structure 50 at the bottom corners.

[0034] In order to conceal the steering wheel 20 within the bottom of the housing structure 50, such as Figure 4 , 5 As shown, the steering wheel 20 is provided with a connecting shaft 21, which includes a horizontal section 211, a vertical section 212, and a connecting section 213 connecting the two. The horizontal section 211 is offset to one side by 10-60° relative to the vertical section 212, preferably 15°, 20°, 25°, or 30°. By using the connecting section 213 to position the steering wheel 20 at the rear, its support frame 30 can be ensured to be installed at the bottom corner of the housing structure 50. By using the built-in installation of the steering wheel and electric wheel, the area between the two can also be efficiently utilized to install the electric telescopic pedal, control module, and external power supply, etc.

[0035] To enable the upper box structure 50 to enter the interior and connect with the support frame 30, and to ensure that the irregularly shaped connecting shaft 11 can rotate and change direction without hindrance, such as Figure 5As shown, a support ring 214 is installed on the vertical section 212. Above the support ring 214, a sleeve is fitted on the outside of the vertical section 212 and a bearing 215 is located between the support frame 30 and the sleeve, thereby completing the rotation operation with the vertical section 212 as the center. The sleeve is inserted and fixed on the box structure 50, and the vertical section 212 can rotate inside it, thus completing its rotation operation.

[0036] Example 2

[0037] In the aforementioned walking assembly, such as Figure 4 , 5 As shown in Figure 6, the control structure includes a control lever 60, which is built into the housing structure 50 and has its top exposed and equipped with a control handle. The bottom of the control lever 60 is rotatably mounted on the support frame 30. A connecting plate 61 is installed at the bottom of the control lever 60, and a connecting plate 62 is installed at the top of the vertical section 212. A connecting plate 63 is installed between the connecting plate 61 and the connecting plate 62.

[0038] The free sections of the horizontal section 211 and the vertical section 212 are both provided with external threads, and the connecting plate 62 is fixed to the top of the vertical section 212 by two sets of nuts.

[0039] like Figure 6 As shown, the locking structure includes a first constraint body 64 and a second constraint body 65 arranged on the outside of the control lever 60. The first constraint body 64 and the second constraint body 65 are respectively distributed on both sides of the control lever 60. One end of the first constraint body 64 and the second constraint body 65 is rotatably set, and the other end is independently installed with an elastic element 66.

[0040] A locking body 67 is independently installed on the outer side of constraint body 1 64 and constraint body 2 65. The position of the locking body 67 relative to the control lever 60 is adjustable. Both the locking body 67 and the constraint body are mounted on a fixed box, which is mounted on the top of the housing structure 50 and located on the top of the support frame 1 30.

[0041] The ends of the first constraint body 64 and the second constraint body 65 that face away from each other and are far from the rotation node are provided with a sloping surface.

[0042] The locking body 67 is provided with a trigger body 68, and the trigger body 68 and the micro switch 69 are positioned correspondingly. The micro switch 69 is connected to an independently set power supply and the electric wheel 10 circuit through a circuit.

[0043] Adjusting the locking body 67 away from the control lever 60 causes the two locking bars on the locking body 67 to move to the ramp position. The restraint body extends outward under the action of the elastic element 66, releasing the restraint of the control lever 60. At this time, the trigger body 68 activates the micro switch 69 to adjust it to riding mode. The steering action can be adjusted through the control lever 60. The control handle integrates a speed lever and a brake lever. Adjusting the locking body 67 closer to the control lever 60 causes the two locking bars on the locking body 67 to move from the ramp position to the flat position. The restraint bodies move closer to each other and stretch and deform the elastic element 66, releasing the restraint on the control lever 60. At this time, the power to the electric wheel 10 is disconnected, and it is in push-pull mode.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
