Description

A telescopic car and its usage method Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a telescopic vehicle and its method of use. Background Technology

[0002] With the continuous development of technology and the improvement of people's living standards, more and more people own cars, bringing them a more comfortable and convenient life experience. However, the increasing number of cars has also put great pressure on traffic, especially urban traffic. The longer a car is, the more interior space it has, providing a better experience for passengers; however, a longer car requires more space when parking, making parking difficult. A narrower car is better for navigating narrow roads, but an excessively narrow width is detrimental to driving stability and interior space. If cars were extendable, their length and width could be adjusted to suit different driving environments, improving comfort and usability.

[0003] Chinese patent CN112776889A discloses a folding and telescopic car that allows for adjustments to vehicle length and seating capacity through folding technology. However, while this folding solution enables adjustment of vehicle length, it also reduces the car's rigidity and impact resistance, thereby lowering its safety.

[0004] Chinese patent CN103612672A discloses a retractable car that achieves lateral retraction of the vehicle body through a special side-opening structure, i.e., vehicle width adjustment. However, the car structure of this solution differs significantly from existing car structures, requiring substantial modifications to existing structures for implementation, resulting in high costs and low commercial value. Furthermore, this solution also reduces the car's rigidity and impact resistance, thereby lowering its safety.

[0005] It is evident that existing technologies can only adjust the length or width of a car individually, and cannot adjust both the length and width simultaneously. Furthermore, while existing technologies can adjust the length or width of a car, they also reduce the car's rigidity and impact resistance, thereby reducing its safety and creating potential safety hazards.

[0006] Therefore, there is an urgent need for a telescopic car and its usage method that can adjust the length and width of the car without reducing its rigidity and impact resistance, thereby improving the car's efficiency, enhancing the user experience, and ensuring the car's safety.

[0007] Summary of the Invention

[0008] The main objective of this invention is to provide a telescopic car and its usage method, which enables the adjustment of the car's length and width without reducing the car's rigidity and impact resistance, thereby improving the car's usage efficiency, enhancing the user experience, and ensuring the car's safety.

[0009] To achieve the above objectives, the present invention provides a telescopic vehicle, which includes a telescopic cargo box, a fluid storage device, and a refueling device.

[0010] The telescopic carriage includes: a first carriage body, a second carriage body, and a telescopic section.

The telescopic section includes one or more sealing telescopic plates. Each sealing telescopic plate includes: a shell, an inner core, a driving device, and a sealing device. The shell accommodates the inner core, which is located inside the shell and can be driven to extend or retract from the shell by the driving device. The driving device drives the inner core to extend or retract from the shell. The sealing device contacts both the shell and the inner core to prevent fluid leakage between them.

[0011] The fluid storage device is used to store shear-thickening materials;

[0012] The filling device is connected to the fluid storage device and the carriage telescopic part, respectively, and is used to fill the shear thickening material in the fluid storage device into the cavity between the shell and the inner core when the inner core extends out of the shell, and to draw the shear thickening material from the sealed cavity back into the fluid storage device when the inner core retracts into the shell.

[0013] As described above, the telescopic vehicle includes a telescopic housing and a supporting anti-collision component. Both the telescopic housing and the supporting anti-collision component are telescopic. The telescopic housing is used to maintain the flatness of the inner and outer surfaces of the vehicle body.

The telescopic cargo box is mounted on the telescopic chassis. The cargo box telescopic section is located above the telescopic section. The telescopic section includes a sealing telescopic beam and a sealing telescopic plate. The sealing telescopic beam includes a shell, a beam core, a drive device, and a sealing device.

The drive device is used to drive the beam core to extend or retract from the shell. The sealing device connects the shell and the beam core respectively to prevent fluid leakage between the shell and the beam core.

[0015] As described above, the telescopic vehicle also includes windows. The windows located in the telescopic section of the vehicle are double-layered. When the telescopic section of the vehicle retracts, the double-layered windows overlap each other. When the telescopic section of the vehicle extends, the window area increases, the double-layered windows separate in opposite directions, and the overlapping area of ​​the double-layered windows decreases.

[0016] The telescopic vehicle described above further includes a temperature control device for the telescopic component, used to regulate and control the temperature of the shear-thickening material injected into the telescopic component.

[0017] In the telescopic vehicle described above, the shear-thickening material stored in the fluid storage device consists of a dispersed phase and a dispersion medium, wherein the dispersed phase is solid particles and the dispersion medium is a low molecular weight liquid.

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the specific implementation methods of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0038] The first embodiment of the present invention is illustrated in Figure 1. Figure 1 is a schematic diagram of a telescopic vehicle according to the first embodiment of the present invention. As shown in the figure, the telescopic vehicle of the present invention includes: a telescopic cargo box 10, a fluid storage device, and a refueling device.

[0039] The telescopic carriage 10 includes a first carriage body 101, a second carriage body 102, and a carriage telescopic section 103. The carriage telescopic section 103 is located between the first carriage body 101 and the second carriage body 102, and is connected to both the first carriage body 101 and the second carriage body 102. The carriage telescopic section 103 is used to change the length or width of the telescopic carriage 10. In this invention, the first carriage body 101, the second carriage body 102, and the carriage telescopic section 103 located between the first carriage body 101 and the second carriage body 102 together constitute the telescopic carriage 10 of the telescopic vehicle of this invention. The first carriage body 101 and the second carriage body 102 can be arranged horizontally or vertically. When the first carriage body 101 and the second carriage body 102 are arranged side-by-side, they can be referred to as the left and right sides of the carriage; when they are arranged front-to-back, they can be referred to as the front and rear sides of the carriage. In this invention, the telescopic carriage 10 may include one or more telescopic sections 103. When multiple telescopic sections are included, the number of carriage bodies can also be increased. For example, if the telescopic carriage includes two telescopic sections, then the telescopic carriage may include a first carriage body, a second carriage body, and a third carriage body. One telescopic section is located between the first and second carriage bodies and is connected to both the first and second carriage bodies respectively, and another telescopic section is located between the second and third carriage bodies and is connected to both the second and third carriage bodies respectively.

[0040] In this invention, the telescopic carriage 103 is telescopic, thus changing the length or width of the telescopic carriage 10. When the first carriage body 101 and the second carriage body 102 are arranged side-by-side, the telescopic carriage 103 is located between them. When the telescopic carriage 103 extends, the width of the telescopic carriage 10 increases; when it retracts, it decreases. When the first carriage body 101 and the second carriage body 102 are arranged front-to-back, the telescopic carriage 103 is also located between them. When it extends, the length of the telescopic carriage 10 increases; when it retracts, it decreases.

[0041] Figure 2 is a schematic diagram of the cross-section of the carriage telescopic part of the present invention. As shown in the figure, the carriage telescopic part 103 includes one or more sealing telescopic plates 104. Since the carriage has six sides, including the front, rear, left, right, top, and bottom sides. When the first carriage body 101 and the second carriage body 102 are arranged in a front-to-back manner, the carriage telescopic part 103 is located between the first carriage body 101 and the second carriage body 102, and is connected to the first carriage body 101 and the second carriage body 102 respectively. It can be seen that the carriage telescopic part 103 is composed of four sealing telescopic plates 104, and its cross-section is "U"-shaped. The four sealing telescopic plates 104 are located on the four sides of the carriage: left, right, top, and bottom. When the sealing telescopic plates 104 of the carriage telescopic part 103 extend simultaneously, the length of the carriage increases. Similarly, when the first carriage body 101 and the second carriage body 102 are arranged side by side, the carriage telescopic part 103 is located between the first carriage body 101 and the second carriage body 102, and is connected to the first carriage body 101 and the second carriage body 102 respectively. At this time, the four sealing telescopic plates 104 of the carriage telescopic part 103 are located on the front, rear, top and bottom four sides of the carriage respectively. When the sealing telescopic plates 104 of the carriage telescopic part 103 extend at the same time, the width of the carriage becomes wider.

[0042] The sealing telescopic plate 104 includes a housing 110, an inner core 111, a driving device, and a sealing device. The housing 110 accommodates the inner core 111, which is located inside the housing 110 and can be driven to extend or retract from the housing 110 by the driving device. The sealing device contacts both the housing 110 and the inner core 111 to prevent fluid leakage between them. In this invention, the driving device can be an electric motor or other suitable driving device. The sealing device can be a sealing ring, sealing strip, sealing ring, etc. In this invention, the inner core 111 is driven to extend out of the housing 110 by the driving device; it can extend completely or partially, and it can also retract completely or partially when retracted.

[0043] In the telescopic vehicle of the present invention, when the inner core 111 of the sealing telescopic plate 104 is located inside the housing 110, the sealing telescopic plate 104 has excellent rigidity and impact resistance because the inner core is solid. When the inner core 111 is driven out of the housing 110 by the driving device, the telescopic vehicle is in an extended state, and a sealed cavity is formed inside the housing 110 of the sealing telescopic plate 104. At this time, the rigidity and impact resistance of the sealing telescopic plate 104 decrease significantly, resulting in a decrease in vehicle safety. To avoid the decrease in rigidity and impact resistance of the sealing telescopic plate 104 when the inner core 111 extends, a shear-thickening material can be injected into the cavity inside the sealing telescopic plate 104 to improve its rigidity and impact resistance. In the telescopic vehicle of the present invention, the injection of shear-thickening material into the cavity inside the sealing telescopic plate 104 is achieved through a fluid storage device and a filling device.

[0044] In this invention, the inner core 111 can also be hollow, with its interior being a cavity. It may already be filled with a shear-thickening material, which is used to achieve rigidity and impact resistance during retraction. Alternatively, it may not have been filled with shear-thickening material. When the inner core 111 extends, in addition to the cavity within the inner core 111 itself, a sealed cavity is also formed between the shell 110 and the inner core 111. The volume of the cavity inside the sealing telescopic plate 104 increases, requiring the injection of more shear-thickening material to enhance the rigidity and impact resistance of the sealing telescopic plate.

[0045] A fluid storage device is used to store shear-thickening materials. In this invention, the fluid storage device can be a storage box, storage silo, storage tank, etc., and can be located inside or outside the vehicle compartment. The fluid storage device stores shear-thickening materials.

[0046] The filling device is connected to the fluid storage device and the telescopic section 103 of the carriage, respectively. It is used to fill the cavity between the housing and the inner core with shear-thickening material from the fluid storage device when the inner core 111 extends out of the housing 110, and to draw the shear-thickening material back from the sealed cavity into the fluid storage device when the inner core retracts into the housing. In this invention, the shear-thickening material can be a liquid material. In this case, the filling device can be a liquid pump. The fluid storage device has an outlet, and the sealing telescopic plate 104 has a liquid inlet, which can be located at the housing 110. The filling device is connected to the outlet of the fluid storage device and the liquid inlet of the sealing telescopic plate 104. When it is necessary to inject shear-thickening material into the cavity inside the sealing telescopic plate 104, the filling device obtains the shear-thickening material from the fluid storage device and injects it into the cavity inside the sealing telescopic plate 104, filling the cavity with shear-thickening material, thereby improving the rigidity and impact resistance of the sealing telescopic plate. When the carriage telescopic section retracts, the shear-thickening material needs to be drawn from the carriage telescopic section back to the fluid storage device through the injection device.

[0047] In this invention, the driving device can also inject shear-thickening material from the fluid storage device into the cavity formed by the telescopic component. For example, the outlet of the fluid storage device is connected to the liquid inlet of the sealing telescopic plate 104. When the driving device drives the inner core 111 of the sealing telescopic plate 104 to extend out of the housing 110, a sealed cavity is formed inside the housing 110 of the sealing telescopic plate 104. The pressure inside the sealed cavity is less than the pressure inside the fluid storage device, so the shear-thickening material is drawn into the sealed cavity.

[0048] In this invention, the dispensing device can also function to drive the telescopic component to extend or retract. For example, the dispensing device obtains shear-thickening material from the fluid storage device and injects it into the interior of the sealing telescopic plate 104 through the liquid injection port of the sealing telescopic plate 104. The injected shear-thickening material expands the sealing telescopic plate 104, causing the inner core 111 to extend out of the housing 110. A sealed cavity is formed inside the sealing telescopic plate 104, which is filled with shear-thickening material.

[0049] Shear-thickening materials are a novel type of smart material that are strain rate-dependent. Shear thickening refers to the increase in fluid viscosity as the shear rate applied to the fluid increases. Based on their morphology, shear-thickening materials can be classified into shear-thickening liquids, shear-thickening gels, and shear-thickening composites; based on their composition, they can be classified into polymer solution systems and nanoparticle / polymer / solution suspension systems. Shear-thickening materials exhibit shear thickening phenomena. In their natural state, they possess good flexibility, but under high strain rate impact loads, due to the compression and shear-induced thickening effect, their viscosity and modulus increase rapidly, thus exhibiting high stiffness. After the external force is removed, the system returns to its original state.

[0050] In this invention, the shear-thickening material stored in the fluid storage device consists of a dispersed phase and a dispersion medium. The dispersed phase is solid particles, including at least one of silica, calcium carbonate, and polymethyl methacrylate. The dispersion medium is a low molecular weight liquid, including at least one of polyethylene glycol, ethylene glycol, and ionic liquid. The shear-thickening material may also include high-strength fibers, such as Kevlar fibers. By adding high-strength fibers to the shear-thickening material, the rigidity and impact resistance of the shear-thickening material can be further improved.

[0051] The rigidity and impact resistance of shear-thickening materials vary depending on the ambient temperature. Therefore, the telescopic vehicle of the present invention also includes a temperature control device for telescopic components, used to regulate and control the temperature of the shear-thickening material injected into the telescopic components. The temperature control device can be an air conditioner, capable of regulating the temperature inside the housing 110, thereby regulating the temperature of the shear-thickening material filling the cavity of the sealing telescopic plate 104, resulting in better impact resistance from the shear-thickening material.

[0052] In this invention, in order to inject or withdraw shear-thickening material into the telescopic part of the carriage more quickly, the temperature of the shear-thickening material can be adjusted by the temperature control device of the telescopic part before injection or withdrawal to increase the fluidity of the shear-thickening material, and then the shear-thickening material can be injected or withdrawn, which can increase the speed of injection or withdrawal of the shear-thickening material.

[0053] The telescopic vehicle of the present invention may have a telescopic compartment consisting of one or more sealing telescopic plates, or it may include a telescopic compartment shell and a supporting anti-collision component. Both the telescopic compartment shell and the supporting anti-collision component are telescopic. The telescopic compartment shell is used to maintain the flatness of the inner and outer surfaces of the compartment, and to provide windproofing, heat insulation, and shielding, making the inner and outer surfaces of the telescopic compartment, the first compartment body, and the second compartment body appear flat and continuous. The supporting anti-collision component is located inside the telescopic compartment shell and provides rigid support. The supporting anti-collision component includes at least one of the following: a sealing telescopic plate, a sealing telescopic column, a sealing telescopic strip, a sealing telescopic tube, and a sealing telescopic spiral column. The sealing telescopic plate, sealing telescopic column, sealing telescopic strip, and sealing telescopic tube are all sealing and telescopic. The sealing telescopic plate, as previously described in detail, is a plate-shaped, sealing, and telescopic component. The sealing telescopic column, sealing telescopic strip, and sealing telescopic tube are similar columnar, strip-shaped, and tubular sealing and telescopic components, and like the sealing telescopic plate, they also include a shell, an inner core, a driving device, and a sealing device. The shell houses the inner core, which is located inside the shell and can be driven to extend or retract from the shell by the driving device. The sealing device contacts both the shell and the inner core to prevent fluid leakage between them. When the inner core extends out of the shell, a sealed cavity is formed between the shell and the inner core, into which a shear-thickening material can be injected to enhance the rigidity and impact resistance of the supporting anti-collision component.

[0054] In this invention, the supporting and anti-collision components of the telescopic section of the carriage include sealing telescopic plates, sealing telescopic columns, sealing telescopic strips, sealing telescopic tubes, sealing telescopic spiral columns, etc. When they function as supporting and anti-collision components, a shear-thickening material needs to be added; if they do not function as anti-collision components, the shear-thickening material may not be added. Alternatively, if one or more sides of the telescopic section of the carriage do not function as supporting and anti-collision components, the supporting and anti-collision components may not be included.

[0055] The telescopic cargo box of the telescopic vehicle is mounted on the chassis. In this embodiment, the chassis of the telescopic vehicle is non-retractable. Therefore, when the length or width of the telescopic cargo box changes, the dimensions and wheelbase of the vehicle chassis do not change, so the relative position of the telescopic cargo box and the chassis changes. Figure 3 is a schematic diagram of the telescopic cargo box extension. As shown in Figure 3, for example, when the first cargo box body 101 and the second cargo box body 102 are arranged in a front-to-back configuration, the telescopic cargo box extension 103 is also located between the first cargo box body 101 and the second cargo box body 102. When the telescopic cargo box extension 103 extends, the length of the telescopic cargo box 10 increases, and the second cargo box body 102 moves backward on the chassis. Therefore, the telescopic cargo box 10 and the chassis can be connected in a movable manner, such as by a sliding rail connection or other suitable means. When the telescopic cargo box extension 103 extends or retracts, the telescopic cargo box changes its relative position with the chassis by moving on the sliding rail. The slide rail can be set on the upper surface of the chassis or on the lower surface of the telescopic carriage 10; the present invention makes no limitation thereto.

[0056] In this invention, the telescopic carriage section can also be used to change the height of the telescopic carriage. The first carriage body 101 and the second carriage body 102 can be arranged vertically. The telescopic carriage section 103 is located between the first carriage body 101 and the second carriage body 102, and is connected to both the first carriage body 101 and the second carriage body 102 to change the height of the telescopic carriage.

[0057] The second embodiment of the present invention is illustrated in Figure 4. Figure 4 is a schematic diagram of the telescopic chassis of the telescopic vehicle according to the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the chassis of the telescopic vehicle in this embodiment is also telescopic. As shown in the figure, the telescopic vehicle also includes a telescopic chassis, which includes: a first chassis body 201, a second chassis body 202, and a chassis telescopic part 203. The chassis telescopic part 203 is located between the first chassis body 201 and the second chassis body 202, and is connected to the first chassis body 201 and the second chassis body 202 respectively, for changing the length or width of the telescopic chassis. The first chassis body 201 and the second chassis body 202 are arranged horizontally or vertically. The telescopic cargo box 10 is installed on the telescopic chassis, and the cargo box telescopic part 103 is located above the chassis telescopic part 203. When the cargo box telescopic part 103 extends or retracts, the chassis telescopic part 203 also extends or retracts accordingly, so that the relative position between the telescopic cargo box 10 and the telescopic chassis does not change.

[0058] In this embodiment, the chassis of the telescopic vehicle is also telescopic. Therefore, when the length or width of the telescopic cargo box changes, the telescopic chassis extension part 203 of the telescopic vehicle will change accordingly, so the relative position of the telescopic cargo box and the chassis will not change. At this time, the telescopic cargo box 10 and the telescopic chassis can be connected by a fixed method, such as screw connection, laser welding, riveting, etc., or other suitable methods. Figure 5 is a schematic diagram of the telescopic vehicle when extended according to the second embodiment of the present invention. As shown in Figure 5, when the cargo box extension part extends, the chassis extension part also extends accordingly, and the vehicle wheelbase increases.

[0059] Since a car chassis includes not only a plate chassis but also a frame, the telescopic chassis extension part of the telescopic car of the present invention includes a sealing telescopic beam in addition to a sealing telescopic plate. The telescopic chassis part may include a sealing telescopic beam 205 and a sealing telescopic plate 104. The sealing telescopic beam includes: a shell, a beam core, a drive device, and a sealing device. The shell is used to accommodate the beam core, which is located inside the shell and can be driven to extend out of the shell by the drive device. The drive device is used to drive the beam core to extend or retract from the shell. The sealing device connects the shell and the beam core respectively to prevent fluid leakage between the shell and the beam core. The sealing telescopic beam 205 operates on a similar principle to the sealing telescopic plate 104; both form a sealed cavity when the shell and core extend, allowing the injection of a shear-thickening material to enhance the rigidity and impact resistance of the sealing telescopic beam or plate, enabling the car to achieve both telescopic flexibility and rigidity and impact resistance. The shell and core of the sealing telescopic plate 104 are plate-shaped, while the shell and core of the sealing telescopic beam 205 are beam-shaped.

[0060] In the telescopic automobile of the present invention, the telescopic section 103 of the telescopic carriage 10 can be positioned between the two side windows of the carriage when adjusting the length of the telescopic carriage 10. In this case, the extension or retraction of the section 103 will not affect the size or glass of the side windows. When the first carriage body 101 and the second carriage body 102 are arranged horizontally, the section 103 is located between the first carriage body 101 and the second carriage body 102. In this case, the section 103 serves as part of the window frame, and its extension or retraction will change the size of the front and rear windows of the automobile.

[0061] Therefore, the telescopic automobile of the present invention, the telescopic carriage 10 also includes windows. When the carriage telescopic part 103 is part of the window frame, the window glass located in the window frame of the carriage telescopic part 103 is double-layered, as shown in Figures 6 and 7. The shaded areas of the windows in the figures represent the overlapping parts of the double-layered window glass. When the carriage telescopic part 103 retracts, the double-layered window glass overlaps each other; at this time, the double-layered window glass can completely overlap or partially overlap. When the carriage telescopic part 103 extends, the window area increases, the double-layered window glass separates in opposite directions, and the overlapping area of ​​the double-layered window glass decreases. At this time, the double-layered window glass can still partially overlap, or the double-layered glass can be fully extended without overlapping, and the double-layered window glass together completely covers the entire window, preventing the window from leaking air.

[0062] At this time, the window glass can be installed on the window frame by means of a sliding rail. Therefore, the outer shell 110 of the carriage telescopic part 103 also includes a sliding rail, and its inner core 111 should also have a sliding rail after it extends out. Moreover, the sliding rail should be continuous with the sliding rail on the outer shell 110 at its extended position, so that the window glass of the window frame where the carriage telescopic part 103 is located can slide continuously when it extends or retracts.

[0063] The telescopic vehicle of this invention can have a telescopic cargo box that is either a passenger car or a freight car. The telescopic component can be used to change the length, width, and height of the passenger car or the freight car, or it can be used to change the size of liquid or gas tanks in the freight car; this invention is not limited to these uses.
