Splitable vehicle system

Abstract

This application relates to a detachable vehicle system, including a driver's vehicle and a cabin. The driver's vehicle has a support frame at its rear, which includes a telescopic component that extends and retracts relative to the driver's vehicle. The cabin can be connected to or separated from the driver's vehicle, and its bottom has multiple outriggers. When the cabin is connected to the driver's vehicle, the telescopic component extends relative to the driver's vehicle and supports the cabin, allowing the cabin to move with the driver's vehicle while it is in motion. When the cabin is separated from the driver's vehicle, the telescopic component retracts relative to the driver's vehicle, and the cabin stands upright on the ground via the multiple outriggers. This allows the driver's vehicle and the living cabin to form a rigid connection during long-distance travel, and can be quickly disassembled into two independent structures at the tourist destination, greatly improving the flexibility and convenience of the vehicle. It not only shortens the vehicle's length to meet the living needs of the vehicle but also avoids the inconvenience of traditional towed vehicles.

Description

Technical Field

[0001] This application relates to the field of automotive manufacturing technology, and in particular to a detachable vehicle system. Background Technology

[0002] With the development of society, tourism has gradually become one of the main ways for people to relax and have fun. In order to meet the needs of both travel and rest during long-distance travel, RV products have emerged. Specifically, an RV is a means of transportation with living furniture and other items installed on the vehicle body, which can be used for both travel and rest.

[0003] Currently, RV products are divided into three categories. The first is the self-propelled RV, which is easy to operate but relatively large in size, making it less flexible for urban travel. The second is the towable RV, which consists of a tow truck and a trailer. Although they can be separated, the separation is very inconvenient and not conducive to maintenance. Moreover, this type of RV is larger in overall size and requires a higher level of driving skill. The third is the trailer RV, which mainly uses the cargo bed of pickup trucks or other freight vehicles to build the living compartment. The living compartment of this type of RV cannot be separated independently. During long-distance travel, there may be situations where the vehicle is used to transport goods. If the living compartment cannot be separated, it will be very inconvenient to transport goods while the vehicle is carrying the living compartment. Summary of the Invention

[0004] Therefore, it is necessary to address the aforementioned shortcomings of existing RV products by providing a detachable vehicle system that can function as an RV for people to live and rest, or as a regular vehicle after being detached.

[0005] According to one aspect of this application, a detachable vehicle system is provided, comprising:

[0006] The driver's vehicle has a support frame at the rear, and the support frame has a telescopic component that can extend and retract relative to the driver's vehicle;

[0007] The cabin is capable of being connected to the driver's vehicle or detached from the driver's vehicle, and the bottom of the cabin is provided with multiple outriggers;

[0008] When the cabin is connected to the driver vehicle, the telescopic assembly unfolds relative to the driver vehicle and carries the cabin, so that the cabin can move together with the driver vehicle when the driver vehicle is in motion.

[0009] When the cabin separates from the driver's vehicle, the telescopic assembly retracts relative to the driver's vehicle, and the cabin stands upright on the ground via the multiple outriggers.

[0010] In one embodiment, the rear of the driver's vehicle is provided with a storage slot, and when the telescopic component retracts relative to the driver's vehicle, the support frame is entirely housed in the storage slot.

[0011] In one embodiment, the telescopic assembly includes two telescopic arms, which are spaced apart and symmetrically arranged in a horizontal direction. Each telescopic arm includes a first arm body and a second arm body that are rotatably connected to each other. One end of the first arm body is rotatably connected to the rear of the vehicle, and the other end is connected to one end of the second arm body.

[0012] One end of the first arm can be controllably rotated relative to the vehicle about an axis extending in the height direction, and drives the other end to rotate relative to the second arm about another axis extending in the height direction, so that the first arm and the second arm are in a folded state or an extended state relative to each other.

[0013] In one embodiment, the support frame further includes a balance bar rotatably connected to the end of the second arm away from the first arm; when the telescopic arm extends, the balance bar moves away from the driver's vehicle; when the telescopic arm retracts, the balance bar moves closer to the driver's vehicle.

[0014] In one embodiment, the outrigger includes multiple push rods nested end to end, wherein the push rod at the head end is connected to the bottom of the cabin, and the push rod at the tail end is used to support the ground. The multiple push rods can be controlled to move together toward the cabin to retract into the cabin, or can be controlled to move together toward the cabin to protrude from the cabin.

[0015] When multiple push rods are exposed outside the cabin, and the push rod at the tail end is supported on the ground, the multiple push rods can move together to extend and retract the outriggers, thereby driving the cabin to rise and fall.

[0016] In one embodiment, the cabin includes multiple sub-cabins nested sequentially and controllably retractable to give the cabin a single compartment or expandable to give the cabin multiple compartments.

[0017] In one embodiment, the telescopic arm has a positioning hole, the bottom of the cabin has a corresponding positioning post, and the end of the positioning post has a barb.

[0018] When the cabin is connected to the driving vehicle, the positioning post is inserted into the corresponding positioning hole, and the barb is hooked onto the telescopic arm.

[0019] In one embodiment, the positioning post includes a plurality of sub-positioning posts spaced apart along a circumferential direction. Each positioning post has a snap-fit ​​portion on its outer circumferential surface. The barbs are provided in a plurality of corresponding forms. Each barb is formed by folding outward along the radial direction of the positioning post from the end of a corresponding sub-positioning post. The barb and a corresponding snap-fit ​​portion form a slot. The plurality of sub-positioning posts can be controllably moved away from each other so that the inner circumferential edge of the positioning hole is confined in the slot, or they can be moved closer to each other so that the positioning post can be withdrawn from the positioning hole.

[0020] In one embodiment, the vehicle system further includes a signal transmitter, a signal receiver, and a control module. The signal transmitter is located on the cabin, the signal receiver and the control module are located on the driver's vehicle, and the signal receiver is communicatively connected to the control module.

[0021] The signal transmitter is used to transmit a position signal that represents the location of the cabin, and the signal receiver is used to receive the position signal and send the position signal to the control module. The control module can send control commands based on the position signal to control the vehicle to reverse towards the cabin and fit against the cabin.

[0022] In one embodiment, the vehicle system further includes a locking assembly comprising a first locking member and a second locking member, the first locking member being fixedly disposed on one of the driver's vehicle and the cabin, and the second locking member being fixedly disposed on the other of the driver's vehicle and the cabin, the first locking member being locked to the second locking member when the driver's vehicle is connected to the cabin.

[0023] The aforementioned detachable vehicle system comprises a driver's vehicle and a cabin. On one hand, a support frame at the rear of the driver's vehicle, equipped with a telescopic component that extends and retracts relative to the driver's vehicle, allows the cabin to be supported when extended relative to the driver's vehicle. This creates a rigid connection between the cabin and the driver's vehicle, enabling the cabin to move along with the driver's vehicle while in motion. This not only meets the user's accommodation needs during travel but also shortens the vehicle's overall length and overcomes the maneuverability difficulties of traditional towed vehicles, significantly improving driving flexibility. On the other hand, multiple outriggers at the bottom of the cabin allow for rapid separation of the cabin from the driver's vehicle when the telescopic arm retracts relative to the driver's vehicle. The cabin then stands upright on the ground via these outriggers, allowing the driver's vehicle to operate independently as a regular vehicle, making urban travel more convenient and flexible.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] This application provides a detachable vehicle system that can be used as a whole to meet people's needs for long-distance travel, residence and cargo transportation, or it can be separated into two parts: one part can be used as a regular vehicle to drive on urban roads, and the other part can be used as an independent tourist camp for people to live and rest or as an independent cargo storage base for storing goods.

[0043] The following description uses a motorhome as an example of a detachable vehicle system to illustrate the structure of the detachable vehicle system in this application. It is understood that in other embodiments, the visual inspection device of this application is not limited to motorhomes, but may also be a truck, etc., and is not limited thereto.

[0044] See Figures 1 to 3 , Figures 1 to 3A schematic diagram of a detachable vehicle system 10 according to an embodiment of this application is shown. The detachable vehicle system 10 (hereinafter referred to as vehicle system 10) provided in this embodiment includes a driver's vehicle 100, a cabin 200, and a support frame 300. The support frame 300 is located at the rear of the driver's vehicle 100, and the cabin 200 can be connected to or separated from the driver's vehicle 100 via the support frame 300. The driver's vehicle 100 can be a common small vehicle, such as a sedan or van. The cabin 200 has a compartment for people to live and rest or for storing goods, and the bottom of the cabin 200 is provided with multiple support legs 400. When the cabin 200 is connected to the driver's vehicle 100, the support frame 300 carries the cabin 200, and the cabin 200 can move together with the driver's vehicle 100 when it is in motion, so that the cabin 200 and the driver's vehicle 100 are as... Figure 1 As shown, they are rigidly connected as a single unit, thus meeting the needs of people for long-distance travel, living, and cargo transport; when the cabin 200 is separated from the driving vehicle 100, as... Figure 2 and Figure 3 As shown, the vehicle 100 can drive independently, and the cabin 200 is supported by multiple outriggers 400, allowing the cabin 200 to serve as an independent tourist camp for people to live, rest, or store goods.

[0045] Specifically, in combination Figures 2 to 4 As shown, in one embodiment, the support frame 300 has a telescopic assembly 310 that can extend and retract relative to the driver's vehicle 100. In one embodiment, the telescopic assembly 310 includes two telescopic arms 311, which are horizontally spaced and symmetrically arranged. Each telescopic arm 311 includes a first arm body 3111 and a second arm body 3112 rotatably connected to each other. One end of the first arm body 3111 is rotatably connected to the rear of the driver's vehicle 100, and the other end is connected to one end of the second arm body 3112. One end of the first arm body 3111 can rotate relative to the driver's vehicle 100 about an axis extending in the height direction, and drive the other end to rotate relative to the second arm body 3112 about another axis extending in the height direction, so that the first arm body 3111 and the second arm body 3112 are in a folded or extended state relative to each other. Figure 5 As shown, when the first arm 3111 and the second arm 3112 are folded together, the first arm 3111 fits against the second arm 3112, and the two are approximately overlapping; Figure 6As shown, when the first arm 3111 and the second arm 3112 are in an extended state, their ends are approximately in a straight line or connected in a straight line. Furthermore, when the telescopic assembly 310 extends or retracts relative to the driving vehicle 100, the rotation direction of the first arm 3111 and the second arm 3112 in one telescopic arm 311 is opposite to the rotation direction of the first arm 3111 and the second arm 3112 in the other telescopic arm 311.

[0046] Thus, when the cabin 200 is connected to the driver's vehicle 100, the telescopic component 310 can unfold relative to the driver's vehicle 100 and support the cabin 200, thereby forming a rigid connection between the cabin 200 and the driver's vehicle 100. The cabin 200 can move together with the driver's vehicle 100 while it is in motion, which not only meets the user's accommodation needs during travel, but also shortens the length of the vehicle and overcomes the disadvantages of difficult handling of traditional towed vehicles, greatly improving the vehicle's driving flexibility. When the cabin 200 is separated from the driver's vehicle 100, the telescopic component 310 retracts relative to the driver's vehicle 100, making the driver's vehicle 100 look no different from an ordinary car, thus occupying less space.

[0047] For a better option, please continue reading. Figures 2 to 4 The driving vehicle 100 is equipped with two built-in motors (not shown in the figure). Each built-in motor is connected to the first arm body 3111 of a corresponding telescopic arm 311, so that each telescopic arm 311 can be automatically extended and retracted by the motor.

[0048] More preferably, based on the above embodiment, the support frame 300 further includes a balance bar 320, which is rotatably connected to the end of the second arm 3112 of the two telescopic arms 311 away from the first arm 3111. When the telescopic arms 311 extend, the balance bar 320 moves away from the driver vehicle 100; when the telescopic arms 311 retract, the balance bar 320 moves towards the driver vehicle 100. Thus, by providing the balance bar 320, the synchronicity of the movement of the two telescopic arms 311 can be better ensured, thereby enabling the cabin 200 to maintain better balance when supported on the telescopic assembly 310.

[0049] Furthermore, in each telescopic arm 311, one end of the first arm body 3111 is connected to a built-in motor inside the driver vehicle 100 via a first connecting shaft 330, the other end of the first arm body 3111 is rotatably connected to one end of the second arm body 3112 via a second connecting shaft 340, and the other end of the second arm body 3112 away from the first arm body 3111 is rotatably connected to the balance bar 320 via a third connecting shaft 350. The first connecting shaft 330, the second connecting shaft 340 and the third connecting shaft 350 are all arranged along the height direction and are parallel to each other.

[0050] For details, please continue reading Figure 6 To ensure the load-bearing capacity of the telescopic boom 311, both the first boom body 3111 and the second boom body 3112 are preferably integral die-cast aluminum alloy parts. In one embodiment, the first boom body 3111 is a straight boom, with a spline hole 3111a cast at one end and a semi-circular structure at the other end, and a first through hole 3111b penetrating through the first boom body 3111. The side wall at this end is also provided with a U-shaped groove connecting the first through hole 3111b, so that the first through hole 3111b is divided into two spaced upper and lower sections by the U-shaped groove, wherein the upper section of the first through hole 3111b is provided with a recessed step. The second arm 3112 is a straight arm symmetrical at both ends, with a straight section in the middle and semi-circular structures at both ends, each slightly thinner than the straight section. Each semi-circular structure has a second through hole 3112a penetrating the second arm 3112. One semi-circular structure is inserted into a U-shaped groove at one end of the first arm 3111, and the second through hole 3112a is coaxial with the first through hole 3111b. The other semi-circular structure is used to connect to the balance bar 320. The balance bar 320 is preferably a one-piece die-cast aluminum alloy part, and a threaded hole coaxial with another second through hole 3112a is provided at the connection point with the second arm 3112.

[0051] Furthermore, the upper end of the first connecting shaft 330 is a steel shaft that matches the built-in motor and is connected to the built-in motor. The lower end has a spline structure and is fixedly connected to the spline hole 3111a opened at one end of the first arm body 3111. Preferably, in order to further prevent loosening between the first connecting shaft 330 and the first arm body 3111, the splined end of the first connecting shaft 330 is also engaged with the first arm body 3111 by a cotter pin, thereby forming a rigid connection between the first connecting shaft 330 and the first arm body 3111. The second connecting shaft 340 is simultaneously inserted into the first through hole 3111b of the first arm body 3111 and a second through hole 3112a of the second arm body 3112. The second connecting shaft 340 is rigidly fitted with the first through hole 3111b and is interference-fitted with the second through hole 3112a. One end of the second connecting shaft 340 is assembled with a lock nut, so that the second connecting shaft 340 rotatably connects the first arm body 3111 and the second arm body 3112 together. One end of the second connecting shaft 340 abuts against the recessed step, so that the second connecting shaft 340 does not protrude from the upper surface of the first arm body 3111. Similarly, the third connecting shaft 350 is simultaneously inserted into another second through hole 3112a of the second arm body 3112 and the threaded hole of the balance bar 320. The threaded end of the third connecting shaft 350 is threadedly engaged with the threaded hole of the balance bar 320, so that the third connecting shaft 350 is rigidly engaged with the balance bar 320 and clearance engaged with the second arm body 3112. At the same time, the second through hole 3112a of the second arm body 3112 connected to the balance bar 320 is also provided with a recessed step, so that the third connecting shaft 350 does not protrude from the upper surface of the second arm body 3112.

[0052] Preferably, the spline hole 3111a and the first through hole 3111b of the first arm body 3111, and the second through hole 3112a of the second arm body 3112 are all coated with anti-loosening adhesive to further prevent loosening of the rigidly connected parts of the first connecting shaft 330 and the first arm body 3111, the second connecting shaft 340 and the second arm body 3112, and the third connecting shaft 350 and the balance bar 320. More preferably, nylon sleeves are embedded in the first through hole 3111b at the connecting end of the first arm body 3111 and the second through hole 3112a at the connecting end of the second arm body 3112 and the first arm body 3111, so that the first arm body 3111 rotates more smoothly relative to the second arm body 3112 via the second connecting shaft 340.

[0053] Furthermore, see Figure 5 The length of the first arm 3111 is slightly longer than the length of the second arm 3112, so that when the first arm 3111 and the second arm 3112 are in a folded state, the first arm 3111 can fit more snugly against the second arm 3112. As an improvement to the above embodiment, such as... Figure 2 and Figure 3 As shown, the rear of the driver vehicle 100 is provided with a storage slot 101. When the telescopic component 310 retracts relative to the driver vehicle 100, the support frame 300 is completely housed in the storage slot 101. That is, the first arm 3111, the second arm 3112 and the balance bar 320 are all housed in the storage slot 101, thereby making the telescopic component 310 occupy less space when retracted.

[0054] It is understood that the telescopic component 310 is not limited to the structure of two symmetrically arranged telescopic arms 311 described in the above embodiments. It can also be a multiple telescopic arms 311 arranged at intervals, a telescopic structure with multiple telescopic arms 311 cross-connected, or a telescopic platform, etc., which are not limited here.

[0055] In addition, in order to ensure that the cabin 200 is firmly fixed on the support frame 300 when the cabin 200 is connected to the driver vehicle 100 (i.e., when the support frame 300 is supporting the cabin 200), the first arm 3111 or the second arm 3112 is also provided with positioning holes 3113. Correspondingly, there is a positioning post 500 at the bottom of the cabin 200. The end of the positioning post 500 is provided with a barb 520. When the cabin 200 is connected to the driver vehicle 100, the positioning post 500 is inserted into the corresponding positioning hole 3113, and the barb 520 is hooked on the telescopic arm 311, so that the cabin 200 can be firmly supported on the support frame 300, thereby preventing the cabin 200 from causing serious bumps when moving together with the driver vehicle 100 in motion.

[0056] In one specific implementation, such as Figure 7 and Figure 8 As shown, the positioning post 500 includes sub-positioning posts 510 spaced apart along a circumferential direction. Each positioning post 500 has a snap-fit ​​portion 511 on its outer circumferential surface. Multiple barbs 520 are correspondingly provided. Each barb 520 is formed by folding outwards radially from the end of a corresponding sub-positioning post 510, and a slot 501 is formed between the barb 520 and a corresponding snap-fit ​​portion 511. Multiple sub-positioning posts 510 can be controllably positioned along a circumferential direction under the control of a drive source such as a motor. Figure 8 The arrows shown are pointing away from each other, so that the outer diameter of the positioning post 500 is increased to be equal to the diameter of the positioning hole 3113, thereby causing the inner periphery of the positioning hole 3113 to abut against the outer diameter of the positioning post 500 and be confined in the slot 501, or as... Figure 7 The two parts are brought closer together so that the outer diameter of the positioning pin 500 is smaller than the diameter of the positioning hole 3113, so that it can be withdrawn from the positioning hole 3113.

[0057] Thus, through the design of the above structure, the positioning column 500 can automatically open or retract to change its outer diameter, realizing the rapid and automatic connection and separation of the driver's vehicle 100 and the living quarters. This allows the driver's vehicle and the living quarters to form a rigid connection during long-distance travel, and can be quickly disassembled into two independent structures, the driver's vehicle 100 and the cabin 200, at the tourist destination, greatly improving the vehicle's flexibility and convenience.

[0058] In one embodiment, the cabin 200 is constructed from an aluminum alloy frame and is a multi-section electrically retractable structure. Specifically, the cabin 200 includes multiple sub-cabins 200, which are nested sequentially and can be controllably retracted to form a single compartment, i.e., retracted into a short cabin 200 with the same cross-section as the vehicle 100. Alternatively, it can be controllably expanded to form multiple compartments, thus allowing the cabin 200 to accommodate two or more people when expanded, while the innermost compartment 200 can also be used as a storage compartment when the vehicle is in motion.

[0059] Furthermore, such as Figure 9 As shown, the outrigger 400 located at the bottom of the cabin 200 is an electrically telescopic outrigger 400 structure, which includes multiple push rods 410 nested end to end. Specifically, it can be a multi-section pen-type continuously variable electric push rod. The push rod 410 located at the front end is connected to the bottom of the cabin 200. Specifically, it can be fixed to the four corners inside the cabin 200 through a connecting flange. The push rod 410 located at the rear end is used to support the ground. Specifically, a support seat can be set at the end of the push rod 410 located at the rear end. Multiple push rods 410 can be controlled to move together toward the cabin 200 to retract and hide inside the cabin 200, or can be controlled to move together toward the cabin 200 to be exposed inside the cabin 200. When multiple push rods 410 are exposed inside the cabin 200 and the push rod 410 at the tail end is supported on the ground, the driver can control the multiple push rods 410 to move together to extend and retract the outriggers 400, thereby raising and lowering the cabin 200, so that the cabin 200 can be stopped at any raising or lowering position.

[0060] Thus, when it is necessary to connect the cabin 200 to the driver vehicle 100, the outriggers 400 can be retracted to lower the cabin 200 to a position where the bottom of the cabin 200 is level with the height of the support frame 300, so that the support frame 300 can support the cabin 200; when it is necessary to detach the cabin 200 from the driver vehicle 100, the outriggers 400 can be extended to raise the cabin 200 to a certain height, so that the telescopic arm 311 of the support frame 300 can retract freely.

[0061] To further improve the reliability of the connection between the driver's vehicle 100 and the cabin 200, the vehicle system 10 also includes a locking assembly 600. The number of locking assemblies 600 can be multiple, for example, such as... Figure 10 As shown, three locking components 600 are respectively provided on both sides of the vehicle system 10. Each locking component 600 includes a first locking member 610 and a second locking member 620. The first locking member 610 is fixedly installed on one of the driver vehicle 100 and the cabin 200, and the second locking member 620 is fixedly installed on the other of the driver vehicle 100 and the cabin 200. The first locking member 610 is locked to the second locking member 620 when the driver vehicle 100 is connected to the cabin 200. This further improves the reliability of the connection between the driver vehicle 100 and the cabin 200, which is already connected to the driver vehicle 100 by the support frame 300, by connecting them through the locking components 600.

[0062] In some embodiments, the locking assembly 600 can be a latch lock structure, wherein the first locking member 610 is a latch, and the second locking member 620 is a hook. The latch is fixedly disposed on both sides of the cabin 200 at the end near the driver's vehicle 100, and the hook is fixedly disposed on both sides of the driver's vehicle 100 at the rear end, and the hook can be engaged with the latch. In other embodiments, the locking assembly 600 can also be a structure such as an extended caliper to replace the latch lock, and the specific design is not limited.

[0063] To further improve the accuracy of the connection between the driver vehicle 100 and the cabin 200, enabling the driver vehicle 100 to be connected to the cabin 200 in one go, in a preferred embodiment, please refer to [the following text is missing]. Figure 2 and Figure 3 The vehicle system 10 also includes a signal transmitter 700, a signal receiver 800, and a control module (not shown). The signal transmitter 700 is mounted on the cabin 200, and the signal receiver 800 and control module are mounted on the driver's vehicle 100. The signal receiver 800 is communicatively connected to the control module. The signal transmitter 700 transmits a position signal representing the location of the cabin 200. The signal receiver 800 receives the position signal and sends it to the control module. For example, the signal receiver 800 can be a sensor, as long as it can receive signals. The control module can automatically control the driver's vehicle 100 to reverse towards the cabin 200 based on the position signal, until the rear of the driver's vehicle 100 is close to the cabin 200. Preferably, a proximity switch can be installed on the driver's vehicle 100 or the cabin 200, and touching the proximity switch can be used to determine that the vehicle is in reverse and control the driver's vehicle 100 to stop.

[0064] In addition, a physical power supply interface for the driver vehicle 100 is provided at the end of the cabin 200 that is used to connect with the driver vehicle 100, which can provide power to components that require electricity, such as the rear taillights and the electric telescopic outriggers 400 on the cabin 200.

[0065] The following combination Figures 1 to 10This application describes the workflow of connecting the driver vehicle 100 to the cabin 200 in the vehicle system 10 provided by this application, as well as the workflow of separating the driver vehicle 100 from the cabin 200.

[0066] When the driver vehicle 100 needs to connect with the cabin 200, firstly, the telescopic component 310 of the support frame 300 is in a retracted state and housed in the storage slot 101 at the rear of the driver vehicle 100; the cabin 200 is also in a retracted state, and the electrically operated lifting outriggers 400 below the cabin 200 are in a raised state, standing the cabin 200 upright on the ground. Then, the driver controls the outriggers 400 via remote control to raise the cabin 200 to its highest point, at which point the bottom of the cabin 200 is higher than the upper surface of the support frame 300; simultaneously, the signal transmitter 700 installed at the front of the cabin 200 starts working, emitting a position signal of the cabin 200's location. Furthermore, the driver issues a movement command to the vehicle 100 via the control keys on the controller or instrument panel. At this time, the signal receiver 800 on the vehicle 100 activates, receives the position signal, and sends it to the control module. The control module then controls the vehicle 100 to automatically adjust its position and activate the reversing function, moving the vehicle to the corresponding position in front of the cabin 200, with the rear of the vehicle 100 close to the front face of the cabin 200. Further, the driver issues an extension command to the telescopic assembly 310 of the support frame 300 via the remote control. At this time, two built-in motors inside the vehicle 100 rotate synchronously in opposite directions, driving the first arm 3111 of the two telescopic arms 311 to rotate synchronously in opposite directions, which in turn drives the second arm 3112 and the stabilizer bar 320 to move accordingly, ultimately extending to the desired design position. At this time, the support frame 300 extends to be directly below the cabin 200.

[0067] Subsequently, the driver uses a remote control to control the outriggers 400 to lower the cabin 200. The cabin 200 slowly descends until it is flush with the upper surface of the support frame 300. During descent, the driver continuously adjusts the relative position of the cabin 200 and the support frame 300 to ensure that the positioning pin 500 at the bottom of the cabin 200 accurately inserts into the positioning hole 3113 on the telescopic arm 311. The barb 520 at the bottom of the positioning pin 500 hooks onto the telescopic arm 311, thus forming a rigid connection between the cabin 200 and the support frame 300. Simultaneously, the outriggers 400 at the bottom of the cabin 200 retract and conceal themselves inside the cabin 200. Furthermore, the driver manually connects the first locking member 610 and the second locking member 620 of the locking assembly 600 to further improve the reliability of the connection between the cabin 200 and the vehicle 100. Finally, the driver connects the power supply to the power socket on the cabin 200 through the small window at the rear of the vehicle 100, thus completing the connection process between the vehicle 100 and the cabin 200.

[0068] When the vehicle 100 needs to separate from the cabin 200, the driver first manually releases the first locking member 610 and the second locking member 620 of the locking assembly 600. Then, the driver issues an unlocking command via remote control, retracting the barb 520 at the bottom of the positioning post 500, allowing the positioning post 500 to exit from the positioning hole 3113 and unlocking the cabin 200 from the support frame 300. Next, the outriggers 400 are controlled to lift the cabin 200, completely separating it from the support frame 300.

[0069] Furthermore, the driver issues a retraction command to the telescopic component 310 of the support frame 300 via remote control. At this time, the two built-in motors located inside the driver vehicle 100 reverse synchronously in opposite directions, and drive the first arm 3111 of the two telescopic arms 311 to reverse synchronously in opposite directions, thereby driving the second arm 3112 and the balance bar 320 to move accordingly, and finally causing the support frame 300 to retract into the storage slot 101 at the rear of the driver vehicle 100, thus completing the separation process between the driver vehicle 100 and the cabin 200.

[0070] Therefore, the aforementioned detachable vehicle system 10 has a simple structure and excellent maneuverability. It allows for rapid and automatic separation of the driver's vehicle 100 and the living cabin, enabling them to form a rigid connection during long-distance travel and quickly disassemble into two independent structures at the tourist destination. This greatly improves the flexibility and convenience of the driver's vehicle 100. It not only shortens the vehicle's length to meet the accommodation needs of the vehicle but also avoids the inconveniences of traditional towed vehicles.

[0071] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
