Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a handle structure for easy assembly and an electric luggage. Background Technology

[0002] Suitcases are popular due to their large capacity, portability, and high security. They are typically used for carrying clothing, personal care items, and souvenirs when traveling or on business trips. However, suitcases are large and heavy, and the physical exertion of traveling is already considerable. Pulling a heavy suitcase adds to the burden of travel. To address this issue, electric suitcases have emerged on the market. Electric suitcases can be ridden, adding convenience and fun to travel.

[0003] Existing electric luggage cases generally include a case body, front and rear wheels mounted on the case body, a steering mechanism connected to the front wheels and controlling their steering, a motor connected to the rear wheels and driving their rotation, 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. The steering mechanism includes a steering rod and a steering handle fixedly mounted on the upper end of the steering rod. The control switch is mounted on the steering handle of the steering mechanism. The connection method between the steering handle and the steering rod is not disclosed; the conventional fixing method is welding.

[0004] However, welding has two disadvantages: First, welding is relatively complicated, and the skill level of welding technicians varies, which may result in the scrapping of some materials and reduce production efficiency. Second, welding the steering handle and steering rod makes it inconvenient to install the control switch. For example, in order to make the wiring connection between the control switch and the motor and battery more aesthetically pleasing, the wiring is usually passed through the inside of the steering handle. If the steering handle and steering rod are welded, the control switch can only be installed on the steering handle. An opening needs to be made at the steering handle, and then the wiring needs to be connected to the motor and battery inside the housing in sequence through the steering handle and steering rod. However, since the steering handle and steering rod cannot be disassembled, the wiring installation is more difficult. Utility Model Content

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0029] This embodiment mainly describes the handle structure for easy assembly, as follows:

[0030] like Figures 1 to 8As shown, the conveniently assembled handle structure includes a steering assembly 2 for controlling the steering of the suitcase body 1. The steering assembly 2 includes a steering riser 21 and a steering cross tube 22. The lower end of the steering riser 21 extends into the suitcase body 1 and is rotatably connected to the suitcase body 1. This connection method allows the steering riser 21 to flexibly control the steering of the suitcase while ensuring the stability of the suitcase during movement. An instrument housing 3 is provided at the upper end of the steering riser 21. The instrument housing 3 includes a housing base 31 and a side cover 32. The housing base 31 has a downward-opening mounting cavity 318, the opening of which matches the outer contour of the steering riser 21. The upper end of the steering riser 21 extends into the mounting cavity 318 from its opening, allowing the housing base 31 to be stably fitted onto the upper end of the steering riser 21. A first mounting groove 311 for mounting the steering cross tube 22 is provided on the side of the housing base 31 near the housing cover. The first mounting groove 311 communicates with the mounting cavity 318. The side wall of the steering cross tube 22 extends into the first mounting groove 311 and abuts against the steering riser 21. The steering cross tube 22 is fixed to the steering riser 21 by fasteners 4. The side cover 32 is located on the side of the steering cross tube 22 away from the housing base 31. When the side cover 32 is placed on the housing base 31, the housing base 31 and the side cover 32 cooperate to enclose the steering cross tube 22. The split design of the housing 31 and side cover 32 allows the steering cross tube 22 to be first fixed to the steering riser 21 with fasteners 4, and then closed by the side cover 32. This not only achieves a stable connection between the steering cross tube 22 and the steering riser 21, but also facilitates the installation and disassembly of the steering cross tube 22, improving the convenience and efficiency of assembly. This detachable connection method avoids the processing difficulties and material waste caused by traditional welding methods, and also facilitates subsequent maintenance and replacement; at the same time, the enclosed structure hides the internal wiring, improving aesthetics. Furthermore, after the steering cross tube 22 is fixed to the steering riser 21, it forms a "T"-shaped structure. The split design of the instrument housing 3 allows the instrument housing 3 to be fixed to the steering cross tube 22 and the steering riser 21 without screws.

[0031] Specifically, the side cover 32 has a second mounting groove 321 corresponding to the first mounting groove 311 on the side near the housing 31. When the side cover 32 is placed on the housing 31, the first mounting groove 311 and the second mounting groove 321 together form a limiting channel that fits the outer contour of the steering cross tube 22. The double-groove enclosure structure precisely limits the position of the steering cross tube 22, preventing the cross tube from loosening due to force displacement during riding, improving steering stability, and enhancing the stability and reliability of the handlebar structure. At the same time, the fitting design of the limiting channel allows the steering cross tube 22 to fit more tightly against the steering riser tube 21, ensuring the precision and smoothness of steering operation.

[0032] Specifically, a slot 312 is provided on the contact surface between the housing 31 and the side cover 32, and an insertion block 322 is provided on the side cover 32 to extend into the slot 312. The slot 312 and the insertion block 322 are interference-fitted. Through the interference fit between the slot 312 and the insertion block 322, the initial positioning and fixing between the housing 31 and the side cover 32 can be achieved, allowing the side cover 32 to be quickly and accurately aligned with the housing 31 during installation, thus improving assembly efficiency. This structure not only enhances the connection strength between the housing 31 and the side cover 32, but also provides stable support for subsequent fastening operations, further improving the overall stability of the handle structure.

[0033] Specifically, the housing 31 is provided with at least two first connecting posts 313, each with a first threaded hole 314 extending along its length. The side cover 32 is provided with second connecting posts 323 corresponding to the first connecting posts 313, each with a connecting hole 325 extending outward from the side cover 32. When the side cover 32 is placed on the housing 31, a screw passes through the connecting hole 325 and engages with the first threaded hole 314 to secure the side cover 32 to the housing 31. This threaded connection further ensures a secure connection between the housing 31 and the side cover 32, making the entire handle structure more stable and reliable, capable of withstanding greater tensile and torsional forces, and extending the product's service life. Simultaneously, the threaded connection facilitates disassembly and maintenance, improving the product's maintainability.

[0034] In the above-mentioned methods, the side cover 32 and the housing 31 can be connected by an interference fit between the insertion block 322 on the side cover 32 and the slot 312 on the housing 31, or by the first connecting post 313 and the second connecting post 323, with a screw passing through the connecting hole 325 and threaded into the first threaded hole 314 to fix the side cover 32 and the housing 31. In addition to the two methods mentioned above, this invention also has a third method for fixing the side cover 32 and the housing 31: first, pre-fixing is achieved by the interference fit between the insertion block 322 on the side cover 32 and the slot 312 on the housing 31; then, a screw passes through the connecting hole 325 and extends into the first threaded hole 314 to fix the side cover 32 onto the housing 31. This third method not only simplifies and facilitates the installation of the housing 31 and the side cover 32, but also enhances the structural stability of the housing 31 and the side cover 32, enabling a detachable connection of the instrument housing 3, which is convenient for installation and subsequent maintenance.

[0035] Specifically, the housing 31 has an upward-opening mounting chamber 315 for mounting instrument components (such as speedometers, battery level indicators, etc.). The bottom of the mounting chamber 315 has a mounting port 316. When the housing 31 is fitted onto the steering riser 21, the mounting port 316 communicates with the interior of the steering riser 21, and the upper end of the steering riser 21 abuts against the lower surface of the mounting chamber 315. A detachable top cover 33 is provided at the opening of the mounting chamber 315 to close the opening. The design of the mounting chamber 315 provides an independent mounting space for the instrument components, facilitating their installation and maintenance. Simultaneously, the detachable top cover 33 makes instrument component replacement more convenient, improving the product's maintainability. By mounting the instrument components inside the housing 31, not only are they protected from external damage, but the handle structure is also made neater and more aesthetically pleasing, enhancing the overall appearance of the product. The mounting port 316 allows wiring to be routed inside the steering riser 21, preventing exposed wiring.

[0036] Specifically, elastic hooks 317 are provided on both sides of the opening of the mounting chamber 315, and hook grooves 331 are provided on the inner wall of the top cover 33 to mate with the elastic hooks 317. The top cover 33 is fixed to the housing 31 by the hook grooves 331 and the elastic hooks 317. This way of engaging the elastic hooks 317 and the hook grooves 331 makes the installation and removal of the top cover 33 more convenient. The top cover 33 can be fixed or separated from the housing 31 simply by pressing or prying it, which further improves the assembly efficiency and maintainability of the product. At the same time, the design of the elastic hooks 317 can effectively prevent the top cover 33 from loosening or falling off during use, ensuring the stable installation of the instrument components.

[0037] Specifically, the side cover 32 has a limiting flange 324 on its surface near the housing 31, and the limiting flange 324 has a "7"-shaped cross-section. When the side cover 32 is placed on the housing 31, the limiting flange 324 hooks onto the inner wall of the mounting chamber 315 near the side cover 32. This design of the limiting flange 324 can effectively prevent the side cover 32 from loosening or falling off during use, further enhancing the connection stability between the side cover 32 and the housing 31, and ensuring the overall performance of the handle structure. At the same time, the "7"-shaped structure of the limiting flange 324 can better adapt to the shape of the inner wall of the mounting chamber 315, providing a more reliable limiting effect.

[0038] Specifically, the fastener 4 consists of a bolt 41 and a limiting block 42 that mates with the bolt 41. The limiting block 42 has a second threaded hole 421 that mates with the bolt 41. Both the steering cross tube 22 and the steering riser tube 21 have corresponding fixing holes 5, and both the steering cross tube 22 and the steering riser tube 21 have at least two fixing holes 5. The number of second threaded holes 421 on the limiting block 42 is equal to the number of fixing holes 5 on the steering cross tube 22 or the steering riser tube 21. Preferably, there are two fixing holes 5 on the steering cross tube 22 and the steering riser tube 21, and the limiting block 42 also has two second threaded holes 421. The distance between the two second threaded holes 421 is equal to the distance between the two fixing holes 5 on the steering riser tube 21. The limiting block 42 can be welded inside the steering riser tube 21 or it can be an independent unit. When the limiting block 42 is welded inside the steering riser 21, the second threaded hole 421 on the steering riser 21 corresponds one-to-one with the fixing hole 5 on the riser. Simply insert the steering cross tube 22 into the first mounting groove 311 so that the fixing hole 5 of the steering cross tube 22 is aligned with the fixing hole 5 of the steering riser 21. Then, pass the bolt 41 through the steering cross tube 22, the steering riser 21 and the second threaded hole 421 in sequence and thread it to the limiting block 42 to fix the steering cross tube 22 on the steering riser 21. When the limiting block 42 is an independent unit, the steering cross tube 22 is inserted into the first mounting groove 311, aligning the fixing hole 5 of the steering cross tube 22 with the fixing hole 5 of the steering riser tube 21. The limiting block 42 is then inserted into the steering riser tube 21 through the mounting port 316 from the opening of the mounting chamber 315, aligning the fixing hole 5 of the steering riser tube 21 with the second threaded hole 421. Finally, the steering cross tube 22 is fixed to the steering riser tube 21 by threading the bolt 41 through the steering cross tube 22, the steering riser tube 21, and the second threaded hole 421. This method of fastening with bolts 41 and limiting blocks 42 securely fixes the steering cross tube 22 to the steering riser tube 21, preventing it from loosening or falling off during use and ensuring the stability and reliability of the handle structure. Simultaneously, the cooperation between bolts 41 and limiting blocks 42 facilitates the installation and removal of the steering cross tube 22, improving the maintainability of the product. This fastener 4 design effectively avoids the processing difficulties and material waste associated with traditional welding methods, while also facilitating subsequent maintenance and replacement. The aforementioned middle limit block 42 can be replaced with a nut, with one nut corresponding to one bolt 41.

[0039] Installation process:

[0040] Align the mounting cavity 318 of the housing 31 with the upper end of the steering riser 21 and slide it downwards until the top of the steering riser 21 abuts against the lower surface of the mounting chamber 315; embed the side wall of the steering cross tube 22 into the first mounting groove 311 of the housing 31, so that it corresponds with the fixing hole 5 of the steering cross tube 22 and the fixing hole 5 of the steering riser 21, and fix the steering cross tube 22 onto the steering riser 21 by the cooperation of the bolt 41 and the limiting block 42; align the insertion block 322 of the side cover 32 with the slot 312 of the housing 31, apply pressure to make the two interference fit pre-fixed, so that the steering cross tube 22 is wrapped in the limiting channel formed by the second mounting groove 321 and the first mounting groove 311; use a screw to pass through the connecting hole 325 of the second connecting post 323 of the side cover 32, and screw it into the first threaded hole 314 of the first connecting post 313 of the housing 31 to lock the side cover 32 onto the housing 31.
