Description

Technical Field

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

[0002] As travel demands for efficiency over long distances increase, traditional manually pulled electric suitcases are no longer sufficient for the needs of large venues such as airports and exhibition halls. Electric drive technology is being integrated into suitcase design. Electric suitcases primarily achieve autonomous movement through integrated hub motors and removable lithium batteries, fundamentally addressing the pain point of "laborious manual pulling." Maximum speeds are generally controlled at 8-13 km / h to ensure safety, and modular battery designs are adapted to aviation and high-speed rail carrying standards. However, many electric suitcases still retain the traditional telescopic handle at the rear for manual dragging in the event of a power outage. Because the telescopic handle (usually 2-3 sections of aluminum alloy tubing, 18-25mm in diameter) occupies the longitudinal area at the rear of the suitcase when retracted, it creates a "vertical columnar space unsuitable for storage." Taking a common 20-24 inch electric suitcase as an example, the cross-section of this handle's mounting cavity is typically 3-5 cm wide and 4-6 cm deep, extending longitudinally through about half the length of the suitcase. This creates obvious "dead corners" when folding clothes, requiring avoidance of the protrusions and wasting space. Furthermore, the bottom mounting bracket of the handle and the storage slot for the top handle further occupy space at the top and bottom of the suitcase, making it impossible to place large items in these areas; only flexible items like clothing can be used to fill the gaps.

[0003] Existing technologies typically replace the traditional built-in double rods with a wide side pull rod, improving space utilization by about 13%. This frees up approximately 3 liters of neat space, enough to store extra folded clothing and toiletries. Some designs completely eliminate the rear pull rod, such as the electric suitcase disclosed in Chinese patent document CN210581366U. This suitcase includes a rideable body, front and rear wheels mounted on the body, a steering mechanism connected to and controlling the front wheel's steering, a motor connected to and driving the rear wheel, a battery electrically connected to the motor, and a control switch mounted on the steering mechanism to control the circuit between the battery and the motor. While this patent eliminates the rear pull rod, maximizing internal storage space, it results in the suitcase being unable to be pushed or pulled normally when the power is off or the suitcase is idle due to resistance from the drive wheel with the hub motor, significantly reducing its practicality.

[0004] Therefore, it is necessary to provide a front-pull electric suitcase that uses the electric suitcase's built-in steering handle as a pull rod and adds a driven wheel to enable the electric suitcase to be pulled forward even when the power is off, thereby reducing the influence of the drive wheel, increasing the storage cavity capacity, and improving user comfort. Summary of the Invention

[0005] The purpose of this application is to provide a front-pull electric suitcase to solve the technical problem in the prior art where the rear pull rod of the electric suitcase occupies the internal storage cavity, resulting in a large amount of design redundancy and affecting the comfort of use.

[0006] The technical solution adopted by this application to solve its technical problem is: a front-pull electric suitcase, including a suitcase body, a steering handle at the front of the suitcase body, a drive wheel and a driven wheel at the bottom of the suitcase body, the drive wheel being located below the steering handle, auxiliary wheel sets being rotatably provided on both sides of the drive wheel at the bottom of the suitcase body, side covers being provided on both sides of the suitcase body, the auxiliary wheel sets being located below the side covers, an installation cavity being formed inside the housing below the side covers, a portion of the auxiliary wheel set being able to extend into the installation cavity, the auxiliary wheel set including a rotating shaft rotatably mounted on the side cover, a wheel fork at the end of the rotating shaft, an auxiliary wheel rotatably mounted on the wheel fork, a snap-fit ​​part and a locking part being provided on the side cover at the installation cavity, the auxiliary wheel part being snap-fitted into the snap-fit ​​part, and the rotating shaft part being locked into the locking part.

[0007] Furthermore, the rotation axis of the auxiliary wheel set is located above the rotation axis of the drive wheel, and the rotation axis of the auxiliary wheel set is located on the side of the drive wheel's rotation axis facing the direction of the box's movement.

[0008] Furthermore, a receiving groove is provided on the bottom wall of the insert part, the receiving groove penetrates the bottom wall of the insert part, the receiving groove is adapted to the auxiliary wheel, and part of the hub of the auxiliary wheel can be rotatably extended and retracted into the receiving groove; an elastic clip is protruding on the side wall of the insert part, the elastic clip is made of elastic metal material, two elastic clips are provided and symmetrically arranged on the two side walls of the insert part, and the two elastic clips are respectively inserted and connected to the two sides of the hub of the auxiliary wheel.

[0009] Furthermore, the auxiliary wheel includes a hub, a tire, and a bearing, and the thickness of the hub is less than the thickness of the tire; the elastic clip is C-shaped, one end of the elastic clip is fixedly connected to the side wall of the insert, and the other end has a gap with the insert, and the protruding side of the elastic clip can abut against the side of the hub of the auxiliary wheel.

[0010] Furthermore, a through groove is provided on the bottom wall of the locking part, the through groove is adapted to the rotating shaft, one end of the rotating shaft can be rotatably extended and retracted into the through groove, and a locking member is provided in the locking part, the locking member can be engaged and connected to the rotating shaft.

[0011] Furthermore, the locking member includes two hooks rotatably disposed on the bottom wall of the locking part. The hooks are provided and symmetrically arranged. A rotating shaft is provided in the middle of the hook. A hook body is formed on one side of the rotating shaft and a reset part is formed on the other side of the hook. The hook body is L-shaped and its end extends to the top of the through groove. The end of the hook body can abut against the side wall of the rotating shaft. A first spring is provided on the two hooks between the reset parts. The two ends of the first spring are respectively connected to the two hooks.

[0012] Furthermore, each of the two hooks is provided with a reset pressure block above the reset part. The surfaces of the two reset pressure blocks facing the hooks are inclined surfaces, which can abut against the outer side of the hooks and push against the reset part. A second spring is provided between the reset pressure block and the locking part. One end of the second spring is connected to the bottom of the reset pressure block, and the other end of the second spring is connected to the bottom wall of the locking part.

[0013] Furthermore, a mounting shaft is detachably connected to the wheel fork, and the auxiliary wheel is rotatably mounted on the mounting shaft.

[0014] Furthermore, a first fastener is threaded to the end of the mounting shaft located outside the wheel fork. The first fastener can abut against the side wall of the wheel fork. A second fastener is threaded to the other end of the mounting shaft. The second fastener passes through the wall of the wheel fork and is coaxially connected to the mounting shaft.

[0015] The beneficial effects of this application are as follows: An auxiliary wheel assembly is added below the steering handle of the suitcase, utilizing the steering handle itself as a pull rod. This allows the suitcase to be pulled forward even when the power is off, while avoiding the influence of the drive wheel, ensuring comfort and stability. The auxiliary wheel assembly has a retracted state and an open / closed state, which are independent of each other. This ensures that the auxiliary wheel assembly cannot detach from the side cover in the retracted state, and in the open / closed state, it stably supports the suitcase and facilitates dragging, further improving stability. Simultaneously, because the electric suitcase can be pulled forward, this application eliminates the need for a rear pull rod, increasing internal storage space, allowing for more luggage to be carried, and improving ease of use.

[0030] 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.

[0031] Please see Figures 1-3This application provides a front-pull electric suitcase, including a suitcase body 10. The suitcase body 10 has a square shell structure. A steering handle 11 is provided at the front of the suitcase body 10. A drive wheel 12 and a driven wheel 13 are provided below the suitcase body 10. The drive wheel 12 is located below the steering handle 11 and at one end of the suitcase body 10. The driven wheel 13 is located away from the drive wheel 12 and at the other end of the suitcase body 10. At the same time, auxiliary wheel sets 20 are rotatably provided on both sides of the drive wheel 12 below the suitcase body 10. The auxiliary wheel sets 20 can support the suitcase body 10 and drive the suitcase body 10 to move under the action of external force. The rotatable auxiliary wheel sets 20 have a retracted state (see...). Figure 2 ) and open / closed state (see Figure 3 When riding, the auxiliary wheel set 20 is in a retracted state. When the power is off and the vehicle is manually pulled (drag state), the auxiliary wheel set 20 is in an open or closed state and is used to support the box body 10, making it easy to manually drag the box body 10.

[0032] Furthermore, the housing 10 includes an annular frame 14 with a ring structure, and side covers 15 are provided on the open surfaces on both sides of the annular frame 14. The auxiliary wheel set 20 is disposed below the side cover 15. The side cover 15 has a shell structure, and an installation cavity 16 is formed inside the shell below the side cover 15. Part of the auxiliary wheel set 20 can extend into the installation cavity 16.

[0033] In this embodiment, the annular frame 14 is made of aluminum alloy to ensure support, and the side cover 15 is made of plastic to reduce weight and facilitate the installation of the auxiliary wheel set 20.

[0034] Understandably, the electric suitcase also contains a battery, control components, speed control handle, and other equipment. For details on the specific structure, please refer to the electric suitcase disclosed in Chinese Patent CN109793327A, which will not be elaborated here.

[0035] Please see Figures 3-6 The auxiliary wheel assembly 20 includes a rotating shaft 21 rotatably mounted on the side cover 15, with a wheel fork 22 at the end of the rotating shaft 21, and an auxiliary wheel 23 rotatably mounted on the wheel fork 22. The side cover 15 has a locking part 17 and a locking part 18 located in the mounting cavity 16. The auxiliary wheel 23 can be locked into the locking part 17, and the rotating shaft 21 can be locked into the locking part 18.

[0036] In the retracted state, the auxiliary wheel 23 is engaged within the engaging portion 17, while the rotating shaft 21 disengages from the locking portion 18 and is positioned below it. In the open / closed state, the rotating shaft 21 is locked within the locking portion 18, and the auxiliary wheel 23 disengages from the engaging portion 17. This ensures that the auxiliary wheel assembly 20 cannot detach from the side cover 15 in the retracted state, and provides stable support for the housing 10 and facilitates dragging in the open / closed state, thereby improving operational stability.

[0037] Specifically, please refer to Figure 6 , Figure 7 , Figure 11 The locking part 17 has a square shell structure. A receiving groove 171 is provided on the bottom wall of the locking part 17. The receiving groove 171 penetrates the bottom wall of the locking part 17 and is adapted to the auxiliary wheel 23. Part of the hub of the auxiliary wheel 23 can be rotatably extended and retracted into the receiving groove 171. An elastic locking element 172 is protruding on the side wall of the locking part 17. The elastic locking element 172 is made of an elastic metal material, such as spring steel. Two elastic locking elements 172 are provided and symmetrically arranged on the two side walls of the locking part 17. The two elastic locking elements 172 are respectively locked and connected to both sides of the hub of the auxiliary wheel 23 to realize the locking connection of the auxiliary wheel 23, so that the auxiliary wheel assembly 20 can be stably locked and connected in the side cover 15 in the retracted state to prevent it from falling out.

[0038] In this embodiment, the auxiliary wheel 23 is a common rubber auxiliary wheel on the market, including a hub, a tire and a bearing. The thickness of the hub is less than the thickness of the tire. The elastic clip 172 is C-shaped. One end of the elastic clip 172 is fixedly connected to the side wall of the clip portion 17, and the other end has a gap with the clip portion 17. The protruding side of the elastic clip 172 can abut against the side of the hub of the auxiliary wheel 23.

[0039] Thus, a variable gap is formed between the two elastic clips 172 made of elastic material. When the side of the auxiliary wheel 23 abuts against the elastic clip 172 and moves, the elastic clip 172 is subjected to pressure and deforms. The shortest distance between the two elastic clips 172 changes with the side profile of the auxiliary wheel 23, and the clamping force on the auxiliary wheel 23 also changes. This results in greater resistance to the entry and exit of the auxiliary wheel 23 within the locking part 17, preventing the auxiliary wheel assembly 20 from automatically detaching from the side cover 15. During the opening and closing process, it can be manually removed from the locking part 17 to ensure stable operation.

[0040] In other embodiments, the elastic clip 172 is a magnet, which magnetically attaches the auxiliary wheel 23 into the clipping part 17.

[0041] Please see Figures 6 to 11 The bottom wall of the locking part 18 is provided with a through groove 181, which is adapted to the rotating shaft 21. One end of the rotating shaft 21 can be rotatably extended and retracted into the through groove 181. The locking part 18 is provided with a locking member 19, which can be engaged with the rotating shaft 21 to lock the rotating shaft 21 in the locking part 18, thereby ensuring the stability of the auxiliary wheel assembly 20 in the open and closed state.

[0042] Specifically, the locking member 19 includes two hooks 191 rotatably disposed on the bottom wall of the locking part 18. Each hook 191 has a pivot in the middle. A hook body 1911 is formed on one side of the pivot, and a reset part 1912 is formed on the other side. The hook body 1911 is L-shaped and its end extends above the through groove 181. The end of the hook body 1911 can abut against the side wall of the pivot 21. The two hooks 191 have a reset part 1912 on the other side. A first spring 193 is provided between the two parts 2. The two ends of the first spring 193 are connected to two hooks 191 respectively. Thus, when the two reset parts 1912 approach each other, the hooks 1911 move away from each other, compressing the first spring 193 and allowing the rotating shaft 21 to slide between the two hooks 1911. When the first spring 193 returns to its original position, the two reset parts 1912 move away from each other, and the hooks 1911 approach each other, locking the rotating shaft 21 between the two hooks 1911. This completes the locking connection of the rotating shaft 21.

[0043] In this embodiment, two latches 191 are respectively provided with reset blocks 192 above the reset part 1912. The surfaces of the two reset blocks 192 facing the latches 191 are inclined surfaces, which can abut against the outer surface of the latches 191. The reset blocks 192 can push against the reset part 1912. A second spring 194 is provided between the reset blocks 192 and the locking part 18. One end of the second spring 194 is connected to the lower part of the reset blocks 192, and the other end of the second spring 194 is connected to the bottom wall of the locking part 18.

[0044] Thus, when the two reset blocks 192 move downwards, the second spring 194 is compressed, and at the same time, the inclined surface of the reset block 192 pushes against the outer side of the hook 191, causing the two reset parts 1912 to move closer together, thereby compressing the first spring 193. At this time, the hooks 1911 move away from each other, and the rotating shaft 21 can slide between the two hooks 1911. When the reset block 192 is released, the second spring 194 resets, and the reset part 1912 loses pressure, causing the first spring 193 to also reset. The two reset parts 1912 move away from each other, and the hooks 1911 move closer together. At this time, the rotating shaft 21 is locked and secured between the two hooks 1911. The locking connection of the rotating shaft 21 is completed.

[0045] In this embodiment, buttons 195 are connected to the two reset blocks 192. The buttons 195 pass through the housing of the locking part 18 and extend outward for easy operation and control.

[0046] In other embodiments, the locking member 19 is a pin, and the rotating shaft 21 has a socket adapted to the pin. When the rotating shaft 21 rotates to a fixed position, the pin is pushed to engage with the rotating shaft 21, thereby locking the rotating shaft 21 into the locking part 18. This ensures the stability of the auxiliary wheel assembly 20 in the open and closed states.

[0047] Please see Figure 6 , Figure 11 The wheel fork 22 is detachably connected to a mounting shaft 24. The auxiliary wheel 23 is rotatably mounted on the mounting shaft 24 using bearings. One end of the mounting shaft 24 has an external thread and extends outward through the wall of the wheel fork 22. The other end of the mounting shaft 24 has an internal thread and abuts against the side wall of the wheel fork 22. A first fastener 25 is threadedly connected to the end of the mounting shaft 24 located outside the wheel fork 22. The first fastener 25 abuts against the side wall of the wheel fork 22. A second fastener 26 is threadedly connected to the other end of the mounting shaft 24. The second fastener 26 passes through the wall of the wheel fork 22 and is coaxially connected to the mounting shaft 24.

[0048] This application shortens the length of the mounting shaft 24 by using internal and external thread design, while ensuring connection strength, thereby reducing the thickness of the auxiliary wheel assembly 20, so that the auxiliary wheel assembly 20 can be closer to the wall of the side cover 15, and reducing the overall width of the box 10.

[0049] Please see Figure 12 , Figure 13 The drive wheel 12 is equipped with a hub motor. The rotation axis of the auxiliary wheel set 20 is located above the rotation axis of the drive wheel 12, and the rotation axis of the auxiliary wheel set 20 is located on the side of the rotation axis of the drive wheel 12 facing the forward direction of the housing 10.

[0050] When riding, the box 10 is placed horizontally, and the auxiliary wheels 23 are retracted into the locking part 17; when towing, the box 10 is tilted, and the auxiliary wheels 23 partially protrude from the outer contour of the drive wheel 12. This ensures that when the box 10 is tilted (i.e., when the box 10 is manually pulled forward), the auxiliary wheels 23 in the auxiliary wheel set 20 can contact the ground, and the drive wheel 12 is suspended in the air, thereby reducing the impact on the drive wheel 12 and improving the stability of use.

[0051] In this embodiment, when the rotation plane of the auxiliary wheel set 20 is parallel to the rotation plane of the drive wheel 12, the auxiliary wheel 23 and the drive wheel 12 jointly contact the ground, thereby ensuring that even if the auxiliary wheel set 20 comes out of the locking part 17 during riding, it will not affect normal riding.

[0052] This application adds an auxiliary wheel set 20 below the steering handle 11 of the suitcase body 10. Utilizing the steering handle 11 of the electric suitcase as a pull rod, it enables forward pulling of the electric suitcase even when the power is off, while avoiding the influence of the drive wheel 12, ensuring comfort and stability during use. The auxiliary wheel set 20 has a retracted state and an open / closed state, which are independent of each other. This ensures that the auxiliary wheel set 20 cannot detach from the side cover 15 in the retracted state, and in the open / closed state, it stably supports the suitcase body 10 and facilitates dragging, further improving stability. Simultaneously, because the electric suitcase can be pulled forward, this application eliminates the need for a rear pull rod, increasing internal storage space, allowing for more luggage to be carried, and improving ease of use.

[0053] 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.
