Description

Technical Field

[0001] This invention relates to the field of luggage technology, and more specifically to an electric luggage. Background Technology

[0002] Electric suitcases, as innovative products that integrate smart technology with daily travel, are gradually playing an increasingly important role in modern society. Their core components include a high-strength suitcase structure, a motor drive system, an intelligent control module, and a power supply device. The suitcase body is mostly made of durable materials such as ABS, PC, or aluminum-magnesium alloy, ensuring not only structural strength but also lightweight design, making them widely applicable to daily travel needs such as business trips, leisure travel, short commutes, and campus transportation.

[0003] The battery powers the built-in motor and drive wheels of the suitcase, as well as the smart control module, playing a crucial role in electric suitcases. To optimize the overall center of gravity distribution, improve stability during dragging, riding, or turning, and reduce the risk of tipping over, the battery of electric suitcases is usually located at the bottom of the suitcase. The bottom space is relatively concentrated and does not affect the internal storage, allowing for a larger capacity battery module to meet the needs of long range and high power output. At the same time, it reduces the risk of accidental operation when users handle the battery. Bottom mounting is currently the mainstream choice for battery placement in electric suitcases.

[0004] However, the battery is located at the bottom of the casing, close to the ground, making it more susceptible to direct impacts from ground vibrations and shocks during long-term use. This is especially true when traversing rough roads, climbing stairs, or cycling, where frequent vibrations are transmitted to the battery itself, potentially causing structural loosening, casing damage, and affecting the stability of the internal cells. Secondly, the relatively enclosed space at the bottom with limited ventilation can prevent the heat generated by the battery during operation from being dissipated effectively and promptly. This heat buildup can lead to risks such as battery bulging and thermal runaway, seriously affecting battery safety and lifespan. Therefore, there is room for improvement. Summary of the Invention

[0005] The purpose of this invention is to provide an electric suitcase to solve the technical problems of existing electric suitcases where batteries are prone to bulging and deformation due to heat accumulation, and where vibrations generated during suitcase dragging can accelerate battery loosening and deformation, affecting battery life and safety.

[0006] To achieve this objective, the present invention adopts the following technical solution: An electric suitcase includes a suitcase body, a battery box, and a battery body. The suitcase body has a recessed mounting position, and the battery box is detachably installed in the mounting position. The battery box contains a battery compartment, and the battery body is placed inside the battery compartment. A shock-absorbing component is provided between the battery compartment and the battery box. A heat dissipation component is provided at the movable end of the shock-absorbing component. When the suitcase body vibrates, the shock-absorbing component drives the heat dissipation component to dissipate heat from the battery compartment.

[0007] Optionally, the heat dissipation assembly includes a cooling chamber, a pressing plate, a liquid guide pipe, and a heat exchange chamber. The heat exchange chamber is disposed on the side wall of the battery compartment, and the cooling chamber is disposed inside the battery box and contains coolant. The liquid guide pipe is used to connect the cooling chamber and the heat exchange chamber. The pressing plate is connected to the shock absorption assembly and is slidably installed at the end of the cooling chamber away from the liquid guide pipe, for pushing the coolant from the cooling chamber to the heat exchange chamber.

[0008] Optionally, the shock absorption assembly includes a shock absorption rod, a push plate, a connecting rod, a limiting rod, and an elastic element. One end of the shock absorption rod is rotatably mounted on the bottom of the battery compartment, and the other end is rotatably connected to the push plate. The limiting rod is fixed inside the battery box, and the push plate slides on the limiting rod. Both ends of the elastic element abut against the push plate and the cooling cavity, respectively. The connecting rod is inserted into the elastic element and is used to connect the push plate and the extrusion plate. The connecting rod and the limiting rod are slidably engaged.

[0009] Optionally, the heat dissipation component further includes a fan, which is disposed at the bottom of the battery compartment for dissipating heat from the battery body, and the bottom of the battery compartment is provided with a through hole.

[0010] Optionally, a trigger cavity is provided on the side of the cooling cavity near the push plate, and a conductive ring is provided on the outer peripheral wall of the push plate. The push plate is slidably installed in the trigger cavity, and the conductive ring is electrically connected to the trigger cavity.

[0011] Optionally, the electric luggage case further includes a cushioning assembly, which includes a cushioning element and a cushioning plate. The cushioning element is disposed on the inner wall of the battery compartment along a first direction, and the cushioning plate is disposed at the free end of the cushioning element. The cushioning plate abuts against the outer wall of the battery body.

[0012] Optionally, the sidewall of the battery body is provided with a first slide rail along the second direction, and the buffer plate is slidably installed in the first slide rail.

[0013] Optionally, the electric luggage case also includes a lifting assembly, which includes a lifting rod and a base. The bottom of the battery compartment is provided with a guide hole, the lifting rod is slidably installed in the guide hole, the base is disposed on the bottom surface of the battery box, the base and the lifting rod are vertically opposite each other, and the top of the lifting rod abuts against the battery body.

[0014] Optionally, a second slide rail is provided at the bottom of the battery body, the second slide rail is arranged along the first direction, and the top of the top rod slides within the second slide rail.

[0015] Optionally, a rolling element is installed on the side of the buffer plate near the battery body, and the rolling element is slidably installed in the first slide rail.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention effectively absorbs vibrations and impacts during the operation of the luggage by arranging shock-absorbing components between the battery compartment and the battery box. Especially when dragging, riding, or traversing bumpy roads, it significantly reduces the direct impact of vibration on the battery, thereby preventing the battery from becoming loose, bulging, or structurally damaged due to uneven stress. At the same time, the heat dissipation component is located at the movable end of the shock-absorbing component, allowing it to operate synchronously during vibration. This enhances the heat exchange efficiency inside and outside the battery compartment, achieving dynamic heat dissipation of the battery compartment, preventing bulging and deformation caused by heat accumulation, extending the battery's lifespan, and improving battery safety.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 This is a schematic diagram of the overall structure of the electric luggage box provided in an embodiment of the present invention; Figure 2 A partial cross-sectional view of an electric luggage box provided in an embodiment of the present invention; Figure 3 for Figure 2 Enlarged view of point A in the middle; Figure 4 for Figure 2 Enlarged view of point B in the middle; Figure 5 for Figure 2 A magnified view of point C in the middle.

[0025] The electric suitcase provided in this embodiment is applicable to scenarios such as business trips, leisure travel, short commutes, and campus transportation. In this embodiment, the battery box structure of the electric suitcase is improved, which reduces battery deformation caused by heat accumulation or external impact, extends battery life, and improves battery safety.

[0026] Please see Figures 1-5 The electric suitcase provided in this embodiment includes a suitcase body 10, a battery box 30, and a battery body 40. The suitcase body 10 has a recessed mounting position 20, and the battery box 30 is detached and installed in the mounting position 20. A battery compartment 50 is provided inside the battery box 30, and the battery body 40 is disposed inside the battery compartment 50. A shock-absorbing component 60 is provided between the battery compartment 50 and the battery box 30. A heat dissipation component 70 is provided at the movable end of the shock-absorbing component 60. When the suitcase body 10 vibrates, the shock-absorbing component 60 drives the heat dissipation component 70 to dissipate heat from the battery compartment 50.

[0027] Specifically, the box body 10 is the main structure of the suitcase, used to carry luggage and provide a mounting base for various functional modules. The box body 10 has a recessed mounting position 20, which is a pre-designed receiving structure. Its shape and size can be designed according to the outline of the battery box 30, enabling stable positioning and embedding of the battery box 30. The battery box 30 is detachably installed in the mounting position 20 via mechanical connectors (such as clips, grooves, screws, etc.), allowing users to quickly remove the battery module for charging, replacement, or maintenance without tools, improving the ease of use and maintenance efficiency of the electric suitcase. The battery box 30 contains a battery compartment 50, a structural space specifically for housing the battery body 40. Its shape and size can be adjusted according to the type of battery used (e.g., lithium-ion battery, lithium iron phosphate battery, etc.). The battery body 40 is typically a power battery module with multiple battery cells, used to provide power to the drive wheels, motor, control module, and other intelligent functional components of the electric suitcase.

[0028] The shock-absorbing component 60 effectively buffers vibrations and impacts when the battery compartment 10 is dragged, ridden, goes up and down stairs, or traverses uneven surfaces, preventing external forces from directly acting on the battery body 40 and preventing the battery from loosening, cracking its outer casing, or suffering internal structural damage due to concentrated mechanical stress. Simultaneously, during the buffering action, the shock-absorbing component 60 triggers the heat dissipation component 70 located at its telescopic end to accelerate the heat exchange rate between the battery compartment 50 and the external air. Through the coordinated action of the heat dissipation component 70 and the shock-absorbing component 60, under high load and external impact, the impact of external impact and heat accumulation on the battery body 40 can be simultaneously suppressed. This significantly reduces safety hazards such as bulging, thermal expansion, and structural deformation caused by heat accumulation and vibration stress, effectively extending the service life of the battery body 40 and improving the safety and reliability of the electric luggage during high-intensity or long-term use.

[0029] Furthermore, the heat dissipation assembly 70 includes a cooling chamber 710, a pressing plate 720, a liquid guide pipe 730, and a heat exchange chamber 740. The heat exchange chamber 740 is disposed on the side wall of the battery compartment 50, the cooling chamber 710 is disposed inside the battery box 30, and coolant 760 is disposed inside it. The liquid guide pipe 730 is used to connect the cooling chamber 710 and the heat exchange chamber 740. The pressing plate 720 is connected to the shock absorption assembly 60 and is slidably installed at the end of the cooling chamber 710 away from the liquid guide pipe 730, and is used to push the coolant 760 from the cooling chamber 710 to the heat exchange chamber 740. Specifically, the cooling chamber 710 is located inside the battery compartment 30 and is used to store the coolant 760. The coolant 760 can be a liquid medium with high heat capacity and thermal conductivity, such as water-based coolant, low-temperature heat transfer oil, or fluorinated liquid. A compression plate 720 is slidably installed at the end of the cooling chamber 710 away from the liquid guide pipe 730. The compression plate 720 is connected to the shock absorption assembly 60 and generates a compression effect in the cooling chamber 710 through the reciprocating motion during vibration. The heat exchange chamber 740 is located in the side wall area of ​​the battery compartment 50. It can be provided with corrugated channels, turbulence structures, or porous inner walls to increase the contact area between the coolant 760 and the outer wall of the battery compartment 50 and enhance the heat exchange efficiency. The liquid guide pipe 730 connects the cooling chamber 710 and the heat exchange chamber 740 to form a controllable liquid flow path, realizing bidirectional flow of the coolant 760 between the two chambers. The liquid guide pipe 730 is a flexible hose.

[0030] During the operation of the luggage compartment, when encountering bumpy roads, steps, or turns, the shock-absorbing component 60 is activated to absorb vibrations. The shock-absorbing component 60 deforms, causing the extrusion plate 720 to slide within the cooling chamber 710. This drives the coolant 760 from the cooling chamber 710 into the heat exchange chamber 740 along the liquid guide pipe 730. Alternatively, when the shock-absorbing component 60 rebounds, it draws the coolant 760 back from the heat exchange chamber 740 into the cooling chamber 710. During the reciprocating flow between the two chambers, the coolant 760 repeatedly contacts the side wall of the battery compartment 50, achieving heat conduction between the surface of the battery compartment 50 and the coolant 760, thereby increasing the heat dissipation rate of the battery body 40 during operation. Utilizing the vibration process to drive the circulation of the coolant 760 has the advantages of high energy efficiency and simple structure. Through the coordinated work of the shock-absorbing and heat dissipation components 70, the battery is protected from mechanical impact while dynamically promoting the outward conduction of battery heat, avoiding heat accumulation caused by prolonged vibration and high power output, and effectively preventing battery bulging, deformation, or even thermal runaway.

[0031] Furthermore, the shock absorption assembly 60 includes a shock absorption rod 610, a push plate 620, a connecting rod 630, a limiting rod 640, and an elastic element 650. One end of the shock absorption rod 610 is rotatably mounted on the bottom of the battery compartment 50, and the other end is rotatably connected to the push plate 620. The limiting rod 640 is fixed inside the battery box 30, and the push plate 620 slides on the limiting rod 640. Both ends of the elastic element 650 abut against the push plate 620 and the cooling cavity 710, respectively. The connecting rod 630 is inserted into the elastic element 650 and is used to connect the push plate 620 and the extrusion plate 720. The connecting rod 630 and the limiting rod 640 are in sliding engagement. Specifically, when the housing 10 is subjected to external impact or vibration, such as colliding with steps or crossing potholes during towing, the vibration is transmitted along the battery compartment 50 to the shock absorber 610, causing the shock absorber 610 to swing up and down at the fulcrum, thereby applying a pushing force to the push plate 620. Since the push plate 620 is slidably mounted on the limiting rod 640, which is fixed inside the battery box 30, the push plate 620 slides along the limiting rod 640 under the drive of the shock absorber 610, compressing the elastic member 650 located on one side of it. The connecting rod 630 is inserted inside the elastic member 650, with one end connected to the push plate 620 and the other end connected to the extrusion plate 720 located in the cooling cavity 710. The connecting rod 630 and the limiting rod 640 are in sliding engagement. When the push plate 620 moves, it drives the extrusion plate 720 to slide within the cooling cavity 710, thereby realizing the sliding of the extrusion plate 720 within the cooling cavity 710. Since one end of the elastic element 650 abuts against the outer wall of the cooling cavity 710, when all the mechanical energy of the push plate 620 is converted into the elastic potential energy of the elastic element 650, the push plate 620 rebounds under the action of the elastic element 650, and the push plate 620 slides along the limiting rod 640. At the same time, the push plate 620 drives the extrusion plate 720 to slide in the opposite direction within the cooling cavity 710, thereby realizing the reciprocating motion of the extrusion plate 720 within the cooling cavity 710, thereby realizing the flow of coolant 760 between the cooling cavity 710 and the heat exchange cavity 740, and accelerating the heat dissipation speed of the battery compartment 50.

[0032] When external vibrations or impacts occur, the vibrations in the battery compartment 50 are transmitted to the push plate 620 under the action of the shock-absorbing rod 610. The push plate 620 compresses the elastic element 650 along the limiting rod 640 and rebounds under the action of the elastic element 650, thus achieving the buffering and shock absorption effect on the battery compartment 50. At the same time, the reciprocating motion of the push plate 620 drives the extrusion plate 720 to reciprocate within the cooling chamber 710, causing the coolant 760 to flow within the heat exchange chamber 740, realizing the active delivery of coolant 760 and heat removal, thereby improving the heat dissipation efficiency of the battery compartment 50. The elastic element 650 can be in the form of a compression spring, a rubber body, or a corrugated elastic element.

[0033] Furthermore, the heat dissipation assembly 70 also includes a fan 750, which is located at the bottom of the battery compartment 50 and is used to dissipate heat from the battery body 40. The bottom of the battery box 30 is provided with a through hole 301. Specifically, the fan 750 is installed at the bottom of the battery compartment 50. Structurally, it can be an ultra-thin DC axial fan 750, a brushless turbine fan, etc., and its size can be matched and selected according to the cross-sectional size of the battery compartment 50. The fan 750 is used to deliver cold air to the surface of the battery body 40 or extract hot air, forming an airflow path to create convective heat transfer within the battery compartment 50. To ensure smooth airflow when the fan 750 is running, a through hole 301 is provided at the bottom of the battery box 30. This through hole 301 is a ventilation opening that penetrates the bottom wall of the battery box 30. Its structure can be a single round hole, a multi-hole array, or a grid-shaped channel to enhance the flow of air between the outside air and the inside of the battery compartment 50. When the battery temperature reaches a set threshold, the fan 750 can be activated by the control circuit to carry heat away from the battery body 40 through forced air convection, effectively reducing the core temperature of the battery.

[0034] Furthermore, a trigger cavity 80 is provided on the side of the cooling cavity 710 near the push plate 620, and a conductive ring 621 is provided on the outer peripheral wall of the push plate 620. The push plate 620 is slidably installed in the trigger cavity 80, and the conductive ring 621 is electrically connected to the trigger cavity 80. Specifically, the trigger cavity 80 is a structural groove or independent cavity formed on one side of the cooling cavity 710, used to accommodate the push plate 620 entering under the drive of the shock absorber 610 and triggering subsequent control actions; a conductive ring 621 is provided on the outer peripheral wall of the push plate 620. The conductive ring 621 can be set as a conductive material ring by electroplating, coating or other methods, and it forms an electrical contact relationship with the conductive contacts or sensing electrodes of the trigger cavity 80; when the external vibration causes the shock absorber 610 to be squeezed, it pushes the push plate 620 to slide along the limiting rod 640 and enter the trigger cavity 80. The conductive ring 621 makes contact with the electrodes of the trigger cavity 80, thus forming a closed circuit of electrical signal; this electrical signal is used to start the fan 750, so that the fan 750 can run automatically in an environment with a certain amplitude of vibration, avoiding the malfunction caused by sensor response lag or external interference in the traditional temperature control system; at the same time, it can prioritize starting the fan 750 to complete preheating and heat dissipation before the battery starts to generate heat or enters a high-load working state, improving the immediacy and effectiveness of heat dissipation. The connection between the conductive ring 621 and the trigger cavity 80 can be a sliding contact, a spring electrode, or a capacitive sensing structure. The specific form can be flexibly selected according to the actual circuit design, which is a conventional design capability of those skilled in the art, so it will not be described in detail here.

[0035] Furthermore, the electric luggage case also includes a buffer assembly 90, which includes a buffer element 910 and a buffer plate 920. The buffer element 910 is disposed on the inner wall of the battery compartment 50 along a first direction, and the buffer plate 920 is disposed at the free end of the buffer element 910, abutting against the outer wall of the battery body 40. Specifically, the buffer assembly 90 includes a buffer element 910 and a buffer plate 920. The buffer element 910 is fixedly disposed on the inner wall of the battery compartment 50 along the first direction (i.e., the width or length direction of the battery). Its structure can be made of flexible materials such as elastic rubber strips, polyurethane pads, and silicone elastic blocks, which have good deformation recovery ability and impact absorption performance. The buffer plate 920 is disposed at the free end of the buffer element 910 and directly abuts against the outer wall of the battery body 40, serving as a load-bearing contact surface. Structurally, it can be a plastic plate, a foam covering, or a buffer body with microstructures. The specific form can be flexibly set according to the shape of the battery and the size of the compartment. This is a conventional technical means in the field and will not be described in detail.

[0036] The buffer 910 and the buffer plate 920 together form a flexible isolation structure. When the battery shifts or swings in the horizontal direction (such as left and right shaking or front and back impact), the buffer plate 920 first contacts the outer wall of the battery and deforms. By compressing the buffer 910, the kinetic energy is absorbed, which significantly reduces the direct rigid collision between the battery and the battery compartment 50 and reduces the risk of damage to the cell packaging, solder joints or structural components caused by high-frequency impact.

[0037] Furthermore, a first slide rail 401 is provided on the side wall of the battery body 40 along the second direction, and a buffer plate 920 is slidably installed in the first slide rail 401. Specifically, when the battery body 40 vibrates or shakes due to an external impact, it may produce vertical and horizontal displacements within the battery compartment 50. When the battery body 40 produces vertical displacement, the buffer plate 920 slides along the first slide rail 401, which can limit the swing of the battery body 40 in the front-back direction, effectively buffering the battery body 40 and preventing the battery from shaking significantly in the front-back direction. At the same time, since the buffer plate 920 is slidably installed in the first track, when the battery body 40 moves a large range in the vertical direction, the buffer plate 920 and the first slide rail 401 limit the large vertical displacement of the battery body 40 within the battery compartment 50.

[0038] Furthermore, the electric luggage compartment also includes a lifting assembly 100, which includes a lifting rod 110 and a base 120. A guide hole 130 is provided at the bottom of the battery compartment 50. The lifting rod 110 is slidably installed within the guide hole 130. The base 120 is located on the bottom surface of the battery box 30, with the base 120 and the lifting rod 110 vertically facing each other. The top of the lifting rod 110 abuts against the battery body 40. Specifically, when the luggage compartment encounters a strong vertical impact while riding, crossing steps, or being dragged, the battery compartment 50 experiences vertical displacement and vibration. During this process, the base 120 contacts the lifting rod 110 and generates a reverse thrust, thereby pushing the lifting rod 110 upwards, which in turn lifts the battery body 40 that is abutting against its top. This causes the battery body 40 to shake to a certain extent and passively move away from the bottom hard contact area of ​​the battery compartment 50. Meanwhile, during the shaking of the battery body 40, the buffer component 90 set on the inner wall of the battery compartment 50 provides multi-directional flexible support to the side wall of the battery, thereby effectively reducing the frequency and impact intensity of rigid collisions between the battery body 40 and the battery compartment 50; without affecting the normal installation state of the battery body 40, it dynamically responds to external vibration loads, forming additional buffer stroke and structural elastic redundancy, thereby improving the impact resistance and stability of the entire battery system in the vertical direction, and further ensuring the integrity and safety of the cells, circuit modules and shell structure during high-intensity use.

[0039] Furthermore, a second slide rail 402 is provided at the bottom of the battery body 40, and the second slide rail 402 is arranged along the first direction. The top of the top rod 110 slides within the second slide rail 402. Specifically, when the suitcase experiences irregular impacts or complex vibrations during use, while the top rod 110 is pushed by the base 120 and generates a vertical lifting effect, its top can slide within the second slide rail 402 below the battery body 40 to a limited extent, thereby absorbing part of the kinetic energy in the front-back direction. This further restricts the front-back displacement of the battery body 40 within the battery compartment 50, effectively preventing structural damage caused by rigid impact of the battery against the inner wall of the battery compartment 50 or excessive deformation.

[0040] Furthermore, a rolling element 930 is installed on the side of the buffer plate 920 near the battery body 40, and the rolling element 930 is slidably installed within the first slide rail 401. Specifically, the rolling element 930 is provided on the side of the buffer plate 920 near the battery body 40 and is slidably installed within the first slide rail 401. When the battery body 40 vibrates or is impacted by external force during the operation of the luggage compartment, the rolling element 930 can roll quickly within the slide rail, reducing the friction between the buffer plate 920 and the slide rail. When the battery is subjected to an instantaneous impact force, the lifting component 100 causes the battery body 40 to be lifted rapidly, quickly transforming the rigid collision with the battery body 40 into a flexible buffer, avoiding a direct and rigid collision between the battery and the side wall of the battery compartment 50, and transforming the impact that might have caused damage to the battery casing or deformation of the internal structure into a flexible displacement during the rolling buffer process, thus protecting the battery body 40.

[0041] In summary, the electric luggage case provided in this embodiment reduces battery deformation caused by heat buildup or external impact, extends battery life, and improves battery safety.

[0042] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
