Description

Technical Field

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

[0002] Electric suitcases are smart travel tools that combine traditional luggage storage functions with electric drive technology. They are typically equipped with a removable lithium battery and are controlled via a knob or mobile app for starting, braking, and speed adjustment. The maximum speed is approximately 13 kilometers per hour, and the range is about 8-15 kilometers. Currently, electric suitcases still retain the structural components of traditional suitcases, such as the rear handle and carrying handle. Because of the need to install batteries, a front steering lever, and drive components, the internal storage space of electric suitcases is often limited. Manufacturers usually optimize the internal structure to achieve efficient space utilization. A typical 20-inch model can achieve a storage capacity of 26L, while a 24-inch model can expand to 48L, generally meeting the needs of short or long-distance travel.

[0003] Expanding the internal storage space of electric suitcases has always been a long-term pursuit for manufacturers. Most ordinary electric suitcases have a double-bar telescopic rear handle, installed at the rear or middle of the suitcase, creating two longitudinal protrusions that occupy space. Taking a common 20-24 inch electric suitcase as an example, the cross-section of the mounting cavity for this type of handle is generally 3-5 cm wide and 4-6 cm deep, running longitudinally through about half the length of the suitcase. This creates obvious "dead corners" when storing items inside, requiring avoidance of the protrusions when folding clothes, resulting in wasted space.

[0004] In existing technologies, replacing the traditional built-in double handle with a wide side handle typically improves 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 handle, 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 handle, 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.

[0005] Therefore, it is necessary for those skilled in the art to provide an electric luggage box with a detachable steering handle to maximize the internal storage space while ensuring that it can still be towed in the event of a power outage, thereby improving portability and practicality. Summary of the Invention

[0006] The purpose of this application is to provide an electric luggage box with a detachable steering handle to solve the technical problem in the prior art where the rear pull rod of the electric luggage box occupies the internal storage cavity, affecting the storage capacity and causing inconvenience in operation.

[0007] The technical solution adopted by this application to solve its technical problem is: an electric luggage case with a detachable steering handle, including a case body, a battery, a control component, and a speed control handle. The case body has a storage cavity inside. The front of the case body is provided with a steering handle, and the rear of the case body is provided with a rear plug-in part. The steering handle includes a fixed part fixedly connected to the case body. A telescopic part is detachably provided in the fixed part. The telescopic part can slide from the inside of the fixed part to the outside of the fixed part along the extension direction of the fixed part. One end of the telescopic part is provided with a handle, and the other end of the telescopic part is provided with a locking part. The telescopic part can be locked to both ends of the fixed part. The rear plug-in part is located in the storage cavity of the case body. The rear plug-in part is located on the top surface of the storage cavity and away from the fixed part. One end of the rear plug-in part penetrates the wall of the case body. The telescopic part is detachably connected to the rear plug-in part. The locking part on the telescopic part can be locked to the rear plug-in part. An electrical connection part is provided in the telescopic part near the locking part. The electrical connection part can be electrically connected to the battery, the control component, and the speed control handle.

[0008] Furthermore, the electrical connection includes a handle connector installed in the telescopic part and a power connector installed in the fixed part. The handle connector is electrically connected to the speed control handle on the handle, and the power connector is electrically connected to the control component.

[0009] Furthermore, spring pins are installed in the handle connector and the power connector respectively, and the ends of the two spring pins extend out of the walls of the telescopic part and the fixed part respectively, and the two spring pins can abut against each other.

[0010] Furthermore, a protective sleeve is provided on the outside of the telescopic part, and a conductive element is provided on the wall of the protective sleeve, with two spring pins respectively abutting against both sides of the conductive element.

[0011] Furthermore, a drive wheel and a driven wheel are provided below the housing. The drive wheel is a hub motor and is located below the steering handle. The length of the rear plug-in part is less than the length of the fixed part.

[0012] Furthermore, a ball-head plunger is provided on the wall opposite the electrical connection part of the fixing part, and the ball head of the ball-head plunger can be engaged in the groove of the outer wall of the telescopic part.

[0013] Furthermore, the handle connector is located on the telescopic part near the fixed part at one end, and the power connector is located on the fixed part near the telescopic part at one end.

[0014] Furthermore, the locking part includes a button located inside the handle, a reciprocating block abutting against the button, and a push rod disposed inside the telescopic part and abutting against the reciprocating block; the top of the button passes through the top wall of the handle and extends outward, one end of the reciprocating block is located between the end of the button and the end of the push rod, and the other end of the reciprocating block abuts against a reciprocating spring.

[0015] Furthermore, a limiting seat is provided at the end of the telescopic part away from the handle. A limiting slider and a pushing block are slidably provided in the limiting seat. One end of the pushing block abuts against the end of the pushing rod, and the other end of the pushing block can push against the limiting slider. At the same time, the limiting slider and the pushing block are perpendicular to each other. One end of the limiting slider abuts against a limiting spring, and the other end of the limiting slider can pass through the wall of the telescopic part and extend outward. The end of the limiting slider can be snapped into the fixing part.

[0016] The beneficial effects of this application are as follows: This application removes the traditional rear pull rod of a suitcase to increase the volume of the storage cavity, maximizing storage space. Simultaneously, it reduces the volume of the rear pull-out part and places it on the suitcase body, ensuring that users can pull the electric suitcase at any time, improving portability and practicality. This application designs the telescopic part of the steering handle to be detachable. When the telescopic part is installed on the fixed part, the electric suitcase can be driven; when the telescopic part is installed on the rear pull-out part, the electric suitcase can be dragged in the power-off state. This greatly improves the practicality and convenience of the electric suitcase, while also increasing the internal storage volume and ensuring optimal performance. Attached Figure Description

Detailed Implementation

[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 1-3 This application provides an electric luggage case with a detachable steering handle, including a case body 10, a storage cavity 11 formed inside the case body 10, a steering handle 20 at the front of the case body 10, a rear insertion part 30 at the rear of the case body 10, a drive wheel 12 and a driven wheel 13 at the bottom of the case body 10, the drive wheel 12 is a hub motor, and the drive wheel 12 is located below the steering handle 20.

[0032] 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.

[0033] Further, please refer to Figures 4-7The steering handle 20 includes a fixing part 22 fixedly connected to the housing 10. The fixing part 22 has a hollow tubular structure. A telescopic part 21 is pluggably disposed inside the fixing part 22. The telescopic part 21 can slide from the inside of the fixing part 22 to the outside along the extension direction of the fixing part 22. One end of the telescopic part 21 is provided with a handle 23, and the other end is provided with a locking part 24. The locking part 24 is used to lock the telescopic part 21 to both ends of the fixing part 22. Thus, in use, the telescopic part 21 is pulled out partially from the fixing part 22 and locked in place by the locking part 24. After use, the telescopic part 21 is inserted into the fixing part 22 and locked in place again by the locking part 24 to complete the storage. At the same time, the telescopic part 21 can be separated from the fixing part 22.

[0034] An electrical connection part 25 is provided inside the telescopic part 21 near the snap-fit ​​part 24. The electrical connection part 25 can be electrically connected to the battery, control components, and speed control handle. Thus, when the telescopic part 21 slides to a fixed position inside the fixed part 22, the electrical connection is completed, and the control of the electric luggage box is realized.

[0035] In this embodiment, the steering handle 20 is located in the storage cavity 11 inside the housing 10, and the housing 10 has a groove (not shown in the figure) to accommodate the handle 23, thereby making the appearance of the housing 10 of this application more regular.

[0036] In other embodiments, the steering handle 20 is located outside the housing 10, thereby reducing its occupation of the storage cavity 11 and maximizing the storage space.

[0037] Please see Figure 11 , Figure 12 In this embodiment, the rear insertion / removable portion 30 is located within the storage cavity 11 of the housing 10. The rear insertion / removable portion 30 is disposed on the top surface of the storage cavity 11 and away from the fixing portion 22, with one end penetrating through the wall of the housing 10. The telescopic portion 21 is pluggably connected to the rear insertion / removable portion 30, and the locking portion 24 can lock the telescopic portion 21 into the rear insertion / removable portion 30. The length of the rear insertion / removable portion 30 is less than the length of the fixing portion 22.

[0038] This application removes the traditional rear pull rod of a suitcase to increase the volume of the storage cavity 11, maximizing the storage space. At the same time, it reduces the volume of the rear plug-in part 30 and places it on the suitcase body 10, ensuring that the user can pull the electric suitcase at any time, improving portability and practicality.

[0039] In other embodiments, the rear plug-in portion 30 is located at the top of the housing 10, and the rear plug-in portion 30 is connected to the telescopic portion 21 by a connector, the connector including but not limited to plug-in buckles.

[0040] Further, please refer to Figures 8-9 The locking part 24 includes a button 241 located inside the handle 23, a reciprocating block 242 abutting against the button 241, and a push rod 244 disposed inside the telescopic part 21 and abutting against the reciprocating block 242; the top of the button 241 passes through the top wall of the handle 23 and extends outward, one end of the reciprocating block 242 is located between the end of the button 241 and the end of the push rod 244, and the other end of the reciprocating block 242 abuts against a reciprocating spring 243.

[0041] The telescopic part 21 has a limiting seat 245 at the end away from the handle 23. A limiting slider 246 and a pushing block 248 are slidably disposed within the limiting seat 245. One end of the pushing block 248 abuts against the end of the pushing rod 244, and the other end of the pushing block 248 can push against the limiting slider 246. Simultaneously, the limiting slider 246 and the pushing block 248 are perpendicular to each other. One end of the limiting slider 246 abuts against a limiting spring 247, and the other end of the limiting slider 246 can pass through the wall of the telescopic part 21 and extend outward. The end of the limiting slider 246 can be snapped into the fixing part 22.

[0042] In use, pressing down on the button 241 causes the reciprocating block 242 and the push rod 244 to press down simultaneously, compressing the reciprocating spring 243. At this time, the end of the push rod 244 presses down on the push block 248, and the push block 248 pushes the limiting slider 246 to retract into the telescopic part 21, allowing the telescopic part 21 to slide freely within the fixed part 22 or disengage from the fixed part 22. When the user releases the button 241, the reciprocating block 242 pushes the button 241 back to its original position under the action of the reciprocating spring 243, and the push rod 244 loses pressure. At this time, the end of the limiting slider 246 passes through the wall of the telescopic part 21 and extends outward under the action of the limiting spring 247. The push block 248 simultaneously pushes the push rod 244 back to its original position. When the end of the limiting slider 246 is engaged in the fixed part 22, the telescopic part 21 and the fixed part 22 are fixed together.

[0043] Understandably, the pushing structure between the locking part 24 and the limiting slider 246 inside can be found in a telescopic rod disclosed in Chinese Patent CN110169634A, and the specific structure will not be described in detail here.

[0044] In this embodiment, the fixing part 22 and the rear insertion part 30 are provided with limiting holes (not shown in the figure). The limiting slider 246 can be inserted and detached into the limiting hole, thereby realizing the insertion and detachment of the telescopic part 21 to the front or rear end of the box body 10, so that the steering handle 20 can temporarily act as a pull rod. While ensuring the increase in the volume of the internal storage cavity 11, it also ensures the convenience and practicality of dragging the electric luggage box when the power is off.

[0045] Further, please refer to Figure 10The electrical connection part 25 includes a handle connector 251 installed in the telescopic part 21 and a power connector 252 installed in the fixed part 22. The handle connector 251 is electrically connected to the speed control handle (not shown in the figure) on the handle 23, and the power connector 252 is electrically connected to the control component. Spring pins 253 are respectively installed in the handle connector 251 and the power connector 252. The ends of the two spring pins 253 extend out of the walls of the telescopic part 21 and the fixed part 22, respectively, and the two spring pins 253 can abut against each other to achieve electrical connection.

[0046] The telescopic part 21 is covered with a protective sleeve 254 made of nylon. The self-lubricating effect of the nylon ensures that the telescopic part 21 can slide stably within the fixed part 22. The protective sleeve 254 has a conductive element 255 on its wall. The conductive element 255 is made of elastic metal material. Two spring pins 253 can respectively abut against the two sides of the conductive element 255. The spring pins 253 are commonly available conductive spring pins.

[0047] A ball-head plunger 256 is provided on the wall opposite the electrical connection part 25 of the fixing part 22. The ball head of the ball-head plunger 256 can be engaged in the groove on the outer wall of the telescopic part 21. The ball-head plunger 256 is a common spring plunger used to ensure the accuracy and stability of the connection between the two spring pins 253. In use, the telescopic part 21 is inserted into the fixing part 22, and the ball head of the ball-head plunger 256 is compressed and retracts inward. At the same time, the conductive end of the spring pin 253 also retracts inward under pressure. When the telescopic part 21 moves to the predetermined position, the ball head of the ball-head plunger 256 pops out and abuts against the outer wall of the telescopic part 21 to achieve positioning. The conductive end of the spring pin 253 also pops out and abuts against the conductive part 255. The two spring pins 253 abut against each other to ensure the stability of the conductivity and improve the performance of this application.

[0048] In this embodiment, the handle connector 251 is located on the telescopic part 21 near the fixed part 22, and the power connector 252 is located on the fixed part 22 near the telescopic part 21. Thus, when the telescopic part 21 extends out of the fixed part 22, the power connector 25 is energized to control the electric luggage. When the telescopic part 21 retracts into the fixed part 22, the handle connector 251 and the power connector 252 in the power connector 25 separate, the power to the drive assembly is disconnected, and the electric luggage cannot be moved, thus achieving power-off placement.

[0049] This application removes the traditional rear pull rod of a suitcase to increase the volume of the storage cavity 11, maximizing storage space. Simultaneously, it reduces the size of the rear plug-in part 30 and places it on the suitcase body 10, ensuring that the user can pull the electric suitcase at any time, improving portability and practicality. This application designs the telescopic part 21 of the steering handle 20 as detachable. When the telescopic part 21 is installed on the fixed part 22, the electric suitcase can be driven; when the telescopic part 21 is installed on the rear plug-in part 30, the electric suitcase can be dragged in the power-off state. This greatly improves the practicality and convenience of the electric suitcase, while also increasing the internal storage volume and ensuring optimal performance.

[0050] 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.
