Description

Technical Field

[0001] This utility model belongs to the field of electric luggage, specifically an electric luggage body frame structure used to enhance the structural strength of the luggage body. Background Technology

[0002] Electric suitcases are innovative travel tools that combine traditional suitcases with electric drive technology. They not only store luggage but also, through built-in motors, batteries, and control systems, offer extended functions such as short-distance commuting and intelligent operation, redefining the convenience of modern travel. The suitcase body, as the main component, is used to hold items and temporarily carry passengers; therefore, it needs to possess a certain level of compressive strength and durability. Most existing electric suitcases use injection-molded parts. Due to the less than ideal structural strength and durability of injection-molded parts, they are prone to deformation under pressure after carrying passengers, which can lead to structural deformation over time. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the issue that existing box structures, which are mostly injection-molded parts, are prone to deformation and have poor durability under pressure.

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

[0005] An electric suitcase frame structure includes:

[0006] Skeleton body, the skeleton body is a frame structure connected end to end;

[0007] The reinforcing plate is installed across the head and tail joints of the frame body and is used to install the corresponding wheel assemblies.

[0008] In the skeleton structure, the skeleton body is a circular, square, elliptical or polygonal structure.

[0009] In the frame structure, the bottom of the frame body is provided with a first recess and a second recess, which are used to install the steering wheel and the power wheel, respectively.

[0010] In the frame structure, the reinforcing plate includes reinforcing member one and reinforcing member two. Reinforcing member one and reinforcing member two are each provided in two sets. Reinforcing member one is provided with a flap at its top, and a mounting plate is installed on the top of the flap. The mounting plate is provided with a connecting hole one for installing the steering wheel and a connecting hole two for installing the control lever. Reinforcing member two is used to install the drive wheel.

[0011] In the skeleton structure, a plurality of ribs are provided on the inner wall of the skeleton along the width direction, including rib one located in the middle and rib two located on both sides of rib one;

[0012] The frame body has a notch, which corresponds to the position of the reinforcing member. A reinforcing member is installed inside the notch, and a constraint strip is provided on the reinforcing member for connecting with the reinforcing member.

[0013] In the frame structure, the reinforcement part is provided with an assembly port for installing the control lever;

[0014] The bottom of the reinforcement component is equipped with constraint component one and constraint component two, which are located on both sides of the control lever. One end of constraint component one and constraint component two are rotatably mounted on the reinforcement component, and the other end is connected to the reinforcement component through a spring component. The reinforcement component is provided with a position-adjustable locking component, and the locking component is provided with a locking strip for using to bring the free ends of constraint component one and constraint component two inward toward the control lever.

[0015] In the skeleton structure, the skeleton body has a plurality of circumferentially arranged concave and convex ribs distributed along the width direction.

[0016] In the skeleton structure, the skeleton body has connecting strips on both sides in the width direction, and several anchors are distributed circumferentially on the connecting strips.

[0017] In the skeleton structure, the exposed length of the rib located at the notch is 5-10 mm.

[0018] In the skeleton structure, the constraint strip is a U-shaped structure and is connected to the corresponding rib strip by anchor bolts.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model adopts a frame body with profiles connected end to end to form a regular structure. The end joints are set at the bottom of the box body, which does not affect the aesthetics of the structure. Reinforcing plates are used for cross-fixing to ensure the structural strength of the entire frame structure. The box body is not easy to deform and is used to enhance the overall structural strength. It can meet the carrying capacity of 220kg and has excellent durability.

[0021] Because the enclosure needs to accommodate components such as control levers, drive wheels, and steering wheels, corresponding holes need to be made in the frame structure. Since these holes affect the overall compressive strength of the frame structure, ribs are added to the inner wall of the frame to increase its compressive strength. A recessed area is provided at the bottom of the frame for mounting the corresponding wheel assemblies. However, this recessed area affects the structural strength of the bottom of the frame. A reinforcing plate is used to address this insufficient structural strength. Simultaneously, the reinforcing plate also serves as the mounting point for the wheel assemblies and control levers, allowing the wheel assemblies, originally mounted directly on the enclosure structure, to be moved to the internal reinforcing structure, resulting in improved mechanical performance.

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

[0034] Example 1

[0035] like Figures 1 to 3 As shown, an electric suitcase frame structure includes:

[0036] The skeleton body 10 has multiple parallel ribs on its inner wall, with a rib width of 5-10mm and a thickness of 1-3mm.

[0037] The reinforcing plate 20 has two sets installed at both ends of the bottom inner side of the frame body 10.

[0038] The skeleton 10 is a profile with its ends connected in a regular structure. The regular structure is circular, square or elliptical, preferably square, and the end-to-end connection is located at the position of the reinforcing plate 20.

[0039] The frame 10 is connected end to end (welded). Traditional box bodies mostly use spot welding at the ends, but the durability and compressive strength are not ideal. Therefore, a reinforcing plate 20 is used at the bottom corner to strengthen it, and the reinforcement can ensure the stability of the structure.

[0040] Example 2

[0041] To facilitate the installation of steering wheels and drive wheels, such as Figures 1 to 3 As shown, a recessed portion 11 and a recessed portion 12 are provided at the bottom of the frame body 10. The recessed portion 11 and the recessed portion 12 are used to install the steering wheel 30 and the power wheel 40, respectively.

[0042] like Figures 1 to 3 , Figure 6 , Figure 8 , Figure 9 As shown, the reinforcing plate 20 includes a first reinforcing member 21 and a second reinforcing member 22. Both the first reinforcing member 21 and the second reinforcing member 22 are provided in two sets. The top of the first reinforcing member 21 is provided with a flap 23. The top of the flap 23 is provided with a mounting plate 24. The mounting plate 24 is provided with a first connecting hole 26 for mounting the steering wheel 30 and a second connecting hole 25 for mounting the control lever 50. The second reinforcing member 22 is used to mount the power wheel 40.

[0043] In this embodiment, the first reinforcing member 21 and the second reinforcing member 22, along with the ribs, are fixed to the two corners at the bottom of the frame 10 with anchors to enhance the structural strength of the bottom. At the same time, a mounting plate 24 is fixed on the first reinforcing member 21 to install the control lever 50 and the steering wheel 30. The control lever 50 and the steering wheel 30 are connected by a connecting rod, so that the control lever 50 controls the angle of the steering wheel 30 to control the direction of travel of the box. By using the reinforcing member to install the corresponding wheel assembly, the wheel assembly that was originally directly installed on the frame 10 is switched to be installed on the reinforcing member, so that the deformation of the frame 10 is effectively controlled and the stress on the box is optimized.

[0044] Example 3

[0045] Because the bottom of the enclosure needs to be fitted with corresponding wheel assemblies and a control lever 50 for enclosure control, the ribbed design was structurally optimized, such as... Figures 1 to 3 As shown, the ribs include a first rib 13 located in the middle and second ribs 14 located on both sides of the first rib 13. The first rib 13 ensures the structural strength of the bottom of the skeleton 10 and is used to fix it to the reinforcing plate with anchors. The second rib 14 is used to reinforce the top of the skeleton 10. Since the top of the reinforcing member 21 needs to be opened to install the control lever 50, the first rib 13 cannot guarantee the overall load-bearing strength. Therefore, the second rib 14 is added on both sides. The second rib 14 includes two ribs with a spacing controlled within the range of 10-15mm.

[0046] The frame body 10 has a notch 15, which corresponds to the position of the reinforcing member 21. A reinforcing member 16 is installed inside the notch 15, and a constraint strip 17 is provided on the reinforcing member 16 for connecting with the rib 13. The exposed length of the rib 13 located at the notch 15 is 5-10mm. The constraint strip 17 has a U-shaped structure and is connected to the corresponding rib 13 by anchor bolts. By connecting the constraint strip 17 and the rib 13 by anchor bolts, the reinforcing member 16 and the rib 13 are connected as a whole structure, ensuring the structural strength at this position. In this embodiment, the portion of the rib 13 located at the notch 15 is cut off, with only 5-10mm exposed, ensuring the overall structural strength after connection.

[0047] Example 4

[0048] In the skeleton structure, such as Figure 4 , 5 As shown in Figures 8, 9, and 10, specifically: the reinforcement member 16 is provided with an assembly port, which is used to install the control lever 50;

[0049] The bottom of the reinforcement member 16 is equipped with a first constraint member 161 and a second constraint member 162. The first constraint member 161 and the second constraint member 162 are located on both sides of the control lever 50. One end of the first constraint member 161 and the second constraint member 162 are rotatably mounted on the reinforcement member 16, and the other end is connected to the reinforcement member 16 through a spring member 163. The reinforcement member 16 is provided with a position-adjustable locking member 164. The locking member 164 is provided with a locking strip 165 for using to bring the free ends of the first constraint member 161 and the second constraint member 162 inward to constrain the control lever 50. The outer side of the control lever 50 is fitted with an outer sleeve. The outer sleeve and the control lever 50 can only move axially. The outer sleeve is provided with a limit bolt (located below the constraint member) to prevent the outer sleeve from coming off.

[0050] Since this embodiment uses a single control lever 50 to control direction, it can operate stably in both riding and non-riding modes, avoiding the risk of tipping over in non-riding mode. Therefore, a structure for releasing or restraining the control lever 50 is provided on the back of the reinforcement member 16 (i.e., the inner side of the housing). By adjusting the locking member 164 to the left, the control lever 50 can be clamped and restrained; by adjusting the locking member 164 to the right, the restraint member can release the control lever 50 under the action of the elastic member 163. The locking member 164 is provided with a control end protruding from the waist-shaped through groove on the reinforcement member 16, used to control the relative position of the locking member 164 relative to the control lever 50.

[0051] To further improve the structural strength of the skeleton 10, the skeleton 10 is provided with a plurality of circumferentially arranged concave and convex ribs along the width direction.

[0052] To facilitate the installation of corresponding side covers on both sides of the frame body 10, such as Figure 2 As shown, a storage cavity is formed inside the skeleton body 10. Connecting strips 18 are provided on both sides of the skeleton body 10 in the width direction, and several anchors are distributed circumferentially on the connecting strips 18.

[0053] 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.
