Description

Technical Field

[0001] This invention relates to the field of transportation vehicle technology, and more particularly to an electrically assisted modular carrying vehicle. Background Technology

[0002] Currently, troops generally use trailers to transport supplies during field marches, training exercises, or rescue operations. However, these vehicles are limited by terrain, making travel particularly difficult on unpaved, narrow mountainous areas and rugged, ravine-ridden roads. While portable vehicles worn around the waist are used, their large weight and size make them inconvenient to carry. Furthermore, the wheel hub motors, controlled by handles, do not match the walking speed and pace, resulting in poor coordination and a high risk of back injuries. The lack of manually controlled, real-time intelligent inflatable airbags hinders rapid movement during deep-water swimming, failing to meet the demands of quick action. Finally, the absence of modular load-bearing modules for quick assembly and disassembly prevents the completion of diverse missions. Summary of the Invention

[0003] This invention discloses an electrically assisted modular carrying vehicle, which aims to solve the technical problems existing in the prior art.

[0004] The present invention adopts the following technical solution:

[0005] An electrically assisted modular carrying vehicle is mounted on a walker's waist strap, comprising a connector unit for attaching and detecting waist tension, a connecting tube unit, a control compartment unit for folding the vehicle for portability, a support tube unit, a modular power supply component for carrying items, and a wiring unit for electrical connection, connected in sequence; wherein, the modular power supply component includes at least one carrying module containing a multi-module outdoor power supply and a hub motor, and the wiring unit includes a remote control handle and a connected controller, the controller being controlled and connected to the hub motor.

[0006] In some embodiments, both the connecting tube unit and the supporting tube unit include a plurality of lightweight connecting tubes and are equipped with inflatable airbags, which are connected to a remote control handle provided in the circuit unit.

[0007] In some embodiments, the upper end of the connecting tube unit is fixedly connected to the joint unit equipped with a tension sensor, and the lower end is fixedly connected to the control chamber unit.

[0008] The support tube unit is provided with a telescopic connecting tube, which is provided with an inner connecting tube and an outer connecting tube that can slide relative to each other, as well as a support tube that passes through them. The two ends of the soft inflatable airbag are respectively fixedly connected to the control chamber unit and the modular power supply component, so that the support tube unit can extend and retract within a preset range.

[0009] In some embodiments, the control compartment unit includes a control compartment housing, a controller installed inside the control compartment housing, a connecting plate installed on the outside of the control compartment housing and fixedly connected to the connecting pipe unit, a cylindrical tube fixedly installed at the bottom of the control compartment housing and fixedly connected to the support pipe unit, and an angle adjuster installed on the side of the control compartment housing for realizing vehicle folding; wherein...

[0010] The angle adjuster includes a fixing unit and an adjusting unit capable of generating relative rotation or locking action. The fixing unit is fixedly connected to the control compartment housing, and the adjusting unit is fixedly connected to the connecting plate. It includes an adjusting handle. Rotating the adjusting handle unlocks the fixing unit and the adjusting unit. Rotating the connecting tube unit makes the whole machine reach a preset folded state. Releasing the adjusting handle locks the fixing unit and the adjusting unit, and the whole machine is in a folded and stable state.

[0011] In some embodiments, the connector unit includes a quick-release connector connected to the waist strap, a tension sensor for detecting the waist tension value, a universal joint for rotatable connection, and an elbow joint fixed to the connecting pipe unit, wherein the elbow joint has a curvature in a preset direction.

[0012] In some embodiments, the modular power supply component includes a support module, a flexible photovoltaic panel mounted on the support module, and a hub motor mounted at the bottom of the support module;

[0013] The load-bearing module includes an outdoor power supply with an external waterproof layer, a battery compartment covered by the outdoor power supply, and an electric air pump connected to the outdoor power supply. The electric air pump is also connected to the inflatable airbag and the controller. The battery compartment is equipped with a connecting device for fixing the load-bearing items and a quick-assembly and disassembly unit.

[0014] In some embodiments, the system further includes an overlapping module that is integrally connected to the carrier module via the quick-assembly unit. The overlapping module includes a combat-oriented carrier module, which includes a combat-oriented module, a stabilizing bracket mounted on the upper part of the combat-oriented module, and an outdoor power supply, a carrier compartment covered by the outdoor power supply, a control system for communicating with the outside world, and a hub motor mounted on the bottom of the carrier compartment.

[0015] In some embodiments, the battery compartment and the side wall of the support tube unit are respectively equipped with torsional elastic shafts at both ends. The torsional elastic shafts are connected to the hub motor through connecting rods, thereby reducing the vibration of the carrying vehicle.

[0016] In some embodiments, the circuit unit further includes a tension sensor installed within the connector unit and power lines and motor control lines for transmission connections between the components; wherein...

[0017] The remote control handle is equipped with a power switch for controlling the hub motor and the electric air pump, and a drive button for controlling the direction and speed of the hub motor. The remote control handle is connected to the controller via a power cord. The controller is connected to the hub motor via a motor control line and to the electric air pump via a power cord. When the controller receives a signal from the remote control handle, it transmits the processed signal command to the hub motor to control the hub motor to move forward or backward at a specified speed, or transmits the command to the electric air pump to perform an inflation action.

[0018] The tension sensor is communicatively connected to the controller, so that when the tension sensor transmits the detected waist tension value of the walker to the controller in the form of an electrical signal, the controller controls the assist value of the hub motor according to a preset threshold.

[0019] The circuit unit is equipped with a waterproof layer.

[0020] In some embodiments, when the pedestrian's walking speed is greater than the vehicle's travel speed, the tension sensor displays positive pressure, and the controller controls the hub motor to provide a preset assist matching the positive pressure; when walking is stopped in an emergency, the tension sensor displays reverse pressure, and the controller controls the hub motor to brake and lock.

[0021] Beneficial effects:

[0022] This invention discloses an electrically assisted modular carrying vehicle, which has the following advantages compared with the prior art:

[0023] An electrically assisted modular carrying vehicle effectively reduces the overall weight by including several lightweight connecting tubes in both the connecting tube unit and the support tube unit. The adjustable angle mechanism and retractable support tube unit allow for simple and quick folding of the entire vehicle centered on the control compartment housing via rotating the adjustable handle and gripping the folding handle. The vehicle is compact and easy to carry. A tension sensor in the connector unit detects the lumbar tension of the walker. This sensor transmits the detected tension value as an electrical signal to the controller. The controller then fine-tunes the assist value of the hub motor based on a preset threshold, ensuring the assist provided by the hub motor is appropriate for walking speed and pace. The matching mechanism effectively avoids injury to the walker's lower back. The remote control handle has a power switch that controls the hub motor and electric air pump, as well as a drive key that controls the hub motor's direction and speed. When the controller receives a control signal from the remote control handle, it controls the hub motor's forward or backward movement and speed, and controls the electric air pump to inflate the airbag in real time. By setting up an outdoor power supply and wiring unit for the airbag and an external waterproof layer, the technical problem of slow movement in deep water swimming is completely solved. By setting up a modular load-bearing module that can be quickly disassembled and assembled, the problem of not being able to meet the requirements of carrying items and performing diversified tasks is completely solved.

[0046] like Figures 1-10 As shown, this invention discloses a technical solution for an electrically assisted modular carrying vehicle:

[0047] An electrically assisted modular carrying vehicle is mounted on a walker's waist harness via a quick-release connector 11. It includes a connector unit 1 for attaching to and detecting the tension on the waist via a tension sensor 75, a connecting tube unit 2, a control compartment unit 3 for folding the vehicle for portability, a support tube unit 4, a modular power supply component 5 for carrying items, and a wiring unit 7 for electrical connection. The modular power supply component 5 includes at least one carrying module containing a multi-module outdoor power supply 522 and a hub motor 51. The wiring unit 7 includes a remote control handle 71 and a connected controller 74, which is controlled and connected to the hub motor 51 and an electric air pump 59.

[0048] The first embodiment provided by the present invention, such as Figures 1-9 As shown:

[0049] An electrically assisted modular carrying vehicle is installed on a walker's waist strap and includes a connector unit 1, a connecting tube unit 2, a control compartment unit 3, a support tube unit 4, a modular power supply component 5, and a wiring unit 7 for electrical connection, which are connected in sequence.

[0050] In this example, the connector unit 1 includes a quick-release connector 11, a cylindrical nut 12, a universal joint 13, a sleeve 14, an elbow 15, and a tension sensor 75 for detecting the tension on the waist is installed inside.

[0051] The elbow joint 15 is made of polyurethane. The elbow joint 15 is inserted into the sleeve 14, and the lower end of the universal joint 13 is inserted into the sleeve 14 to connect with the elbow joint 15. The screw holes on the sleeve 14 are aligned with the screw holes on the universal joint 13 and the elbow joint 15. After passing the mounting screws through, a nut (not shown in the figure) is used for tightening. The cylindrical nut 12 is inserted into the upper part of the universal joint hole 131 and welded or fixed with glue. The tension sensor 75 is screwed into the cylindrical nut 12, and the quick-release joint 11 is inserted into the tension sensor 75 and fixed with a nut inside the quick-release joint 11. The other end of the quick-release joint 11 is attached to the walker's waist strap. The elbow joint 15 is fixed to the connecting pipe unit 2. The elbow joint 15 has an upward curvature, providing a gap between the person and the vehicle for easy walking. The universal joint 13 allows the quick-release joint 11 to rotate freely relative to the vehicle being pulled below. See [reference needed]. Figure 1 , Figure 2 .

[0052] In this example, the connecting tube unit 2 includes a connecting tube unit 2, an internal connecting tube 21, a connecting joint 22, a connecting tube 23, and an upper inflatable airbag 24.

[0053] The upper ends of three polyurethane connecting pipes 23 are respectively inserted into connecting joints 22 with three through holes arranged in an equilateral triangle. The inner connecting pipe 21 is inserted into the connecting pipes 23 on both sides. After aligning the threaded holes, screws (not shown in the figure) are used to fix them in place. The elbow joint 15 is inserted into the middle connecting pipe 23. After aligning the threaded holes, screws are used to fix it in place. The upper inflatable airbag 24 is fixed to the connecting pipe 23 with fasteners, laid flat, so as to provide maximum buoyancy when the vehicle enters the water. The lower ends of the three connecting pipes 23 are respectively fixed to the control chamber unit 3. See [reference needed]. Figure 1 , Figure 3 .

[0054] In this example, the control compartment unit 3 includes a control compartment housing 37, a control compartment cover 38, an angle adjuster 35 installed on the left side wall of the control compartment housing 37 for folding the vehicle, and a rotating shaft 372 installed on the right side wall of the control compartment housing 37. The rotating shaft 372 is movably connected to the central hole 332 of the right side connecting plate 33 installed on the right side of the control compartment housing 37. The upper connecting hole 331 of the right side connecting plate 33 is firmly connected to the connecting hole on the right wall of the connecting plate 32 located on the upper part of the control compartment housing 37 by fasteners. A cylindrical tube 31 connected to the connecting tube unit 2 is fixedly mounted on the connecting plate 32, and a folding handle 311 is fixedly connected between the cylindrical tubes 31 on the connecting plate 32, which serves to stabilize the connecting tube unit 2 and to hold it when folding. A controller 74 is installed inside the control compartment housing 37 and the cylindrical tube 31 fixedly connected to the support tube unit 4 is installed at the bottom of the control compartment housing 37.

[0055] The structure of the angle adjuster 35: The rotating spring 352 is placed in the center of the base plate 351. Three sliders 353 are respectively placed in the three slots 3511 of the base plate 351, with their bottom surfaces aligned with the outer surface of the rotating spring 352. The outer teeth 3531 of the sliders 353 on the outside of the sliders 353 match and mesh with the inner teeth 3551 of the cover plate 355 on the inner sidewall. The upper end of the sliders 353 is provided with a protrusion 3532. A limiting plate 354 is installed between the sliders 353 and the cover plate 355. The limiting plate 354 is provided with three... The elongated slide 3541 has a protruding post 3532 inserted into it. The bottom surface of the cover plate 355 is flush with the base plate 351. The outer cover 356 is placed over the cover plate 355 to cover the entire part. The adjusting handle 357 is inserted into the center hole of the angle adjuster 35. The square post is inserted into the square holes of the cover plate 355, the limiting plate 354, and the rotating spring 352 in sequence. The cylindrical section at the end is inserted into the cylindrical center hole of the base plate 351 to form a whole. At this time, the angle adjuster 35 is in a stable locked state.

[0056] The angle adjuster 35 is placed into the housing mounting hole 371 on the left side wall of the control compartment housing 37. It includes a fixing unit and an adjustment unit. The fixing unit includes a base plate 351. The base plate 351 is welded to the angle adjuster connecting plate 36 placed in the installation space 39 and then fixed to the control compartment housing 37 with screws (not shown in the figure), and is fixedly connected to the control compartment housing 37 as a whole. The adjustment unit includes a rotating spring 352, a slider 353, a limiting plate 354, a cover plate 355 and an adjustment handle 357. The cover plate 355 is fixedly connected to the through hole on the left side wall of the connecting plate 32 through the screw hole on the left connecting plate 34 and screws (not shown in the figure).

[0057] Insert the six protruding positioning protrusions 3552 on the surface of the angle adjuster 35 cover plate 355 into the corresponding positioning holes of the left connecting plate 34, and fully weld the joint between the positioning holes and the positioning protrusions 3552; rotatably connect the central hole 332 of the right connecting plate 33 to the right side wall of the control compartment housing 37 through the rotating shaft 372; cover the control compartment cover plate 38 on the control compartment housing 37 and fix it with screws; place the connecting plate 32 between the left connecting plate 34 and the right connecting plate 33; align the threaded holes on both sides of the connecting plate 32 with the threaded holes on the upper end of the left connecting plate 34 and the right connecting plate 33 respectively, and fix them with screws; the rear wall of the connecting plate 32 is attached to the rear wall of the control compartment housing 37.

[0058] Three cylindrical tubes 31 are installed on the upper surface of the connecting plate 32, each containing an inner connecting tube 21. Three cylindrical tubes 31 are also installed on the lower surface of the control chamber housing 37, each containing an inner connecting tube 21. The lower ends of the three connecting tubes 23 are inserted into the upper connecting tubes 21 and fixedly connected by fasteners. The three cylindrical tubes 31 with inner connecting tubes 21 installed on the lower surface are fixedly connected to the support tube unit 4 by fasteners. The control chamber housing 37 has through holes (not shown in the figure) for wiring. (See attached diagram.) Figure 1 , Figure 4 , Figure 7 .

[0059] In this example, when the vehicle is folded, the adjusting handle 357 is moved, causing the limiting plate 354 to rotate. The limiting plate 354 moves the protrusion 3532 through the slide groove 3541, thereby causing the slider 353 to move and retract along the slot 3511 on the base plate 351. At this time, the outer teeth 3531 of the slider 353 on the outside separate from the inner teeth 3551 of the cover plate 355 on the inside, allowing the cover plate 355 to rotate freely. Then, by holding the folding handle 311 and rotating it, the vehicle can be folded. The entire machine is now folded with the control compartment housing 37 as the center. When folded to the correct position, the adjusting handle 357 is released. At this time, the rotational expansion of the rotating spring 352 pushes the slider 353 outward along the slot 3511 of the base plate 351, causing the outer teeth 3531 of the slider 353 to re-engage with the inner teeth 3551 of the cover plate 355. At this time, the positions of the cover plate 355 and the base plate 351 are relatively fixed and cannot rotate freely, thus ensuring that the folded vehicle is in a stable state. See [link / reference]. Figure 4 , Figure 7 .

[0060] In this example, the support tube unit 4 is made of polyurethane material and includes a telescopic connecting tube 41 and a lower inflatable airbag 42. The telescopic connecting tube 41 has an inner connecting tube 411 and an outer connecting tube 413 that can slide relative to each other, and a support tube 412 passing through them. The support tube 412 is inserted into the inner polyurethane tube 411, and the inner polyurethane tube 411 and the support tube 412 are inserted together into the outer polyurethane tube 413. The outer polyurethane tube 413 and the support tube 412 are fixed together in the cylindrical tube 31 at the top of the battery compartment 521 with screws. The inner polyurethane tube 411 is fixed in the cylindrical tube 31 installed at the bottom of the control compartment housing 37 with screws. The upper end of the soft lower inflatable airbag 42 is fixedly connected to the control compartment unit, and the lower end is fixedly connected to the battery compartment 521, so that the support tube unit 4 can extend and retract within a preset range. When the whole machine is folded, the length can be shortened. See Figure 1 , Figure 5 , Figure 6 .

[0061] In this example, the modular power supply component 5 includes a first support module 52, a modular flexible photovoltaic panel 57 mounted on the first support module 52, and a hub motor 51 mounted on the bottom of the first support module 52.

[0062] Place the torsion rubber shaft 56 into the square tube at the rear of the battery compartment 521. Slide the square tube sleeve 54 onto the torsion rubber shaft 56 and insert it into the square tube at the rear of the battery compartment, with its surface flush with both ends of the square tube at the rear of the battery compartment 521. Secure it with screws. Connect the connecting rod 53 to the torsion rubber shaft 56 with a flat key (not shown in the figure) and then lock the flat key to the connecting rod 53 with a nut. Insert the hub motor 51 into the lower end hole of the connecting rod 53. On the other side of the connecting rod 53, put the connecting pad 55 onto the shaft of the hub motor 51 and then lock it with a nut. This completes the installation of the hub motor 51. The torsion rubber shaft 56 reduces the vibration of the carrying vehicle. The two parts of the latch 524 are fixed to the battery compartment 521 and the battery cover 523 respectively with screws. The multi-module outdoor power supply 522 is placed in the battery compartment 521. At the same time, an electric air pump 59 is also installed in the battery compartment 521. The electric air pump 59 is connected to the upper inflatable airbag 24 and the lower inflatable airbag 42 through an air tube. The electric air pump 59 is connected to the multi-module outdoor power supply 522 for power supply and is connected to the controller 74. The controller 74 is then connected to the remote control handle 71. The rotating shaft 571 is inserted into the through hole in the battery compartment 521. Rotary springs 572 are installed on both ends of the rotating shaft 571. The flexible photovoltaic panel 57 is installed on the rotating springs 572. After the battery cover 523 is closed, the latch 524 is fastened. The latch 524 has two separate parts, which can realize quick installation and removal with other modules.

[0063] A rope 58 is also installed outside the battery compartment 521 to tie the load placed on the upper surface of the battery compartment 521. The multi-module outdoor power supply 522 is equipped with a waterproof layer (not shown in the figure). Three cylindrical tubes 31 are also fixedly installed on the square tube at the rear of the battery compartment 521. The internal connecting tubes 21 are installed inside and fixedly installed with the support tube 412 and the external connecting tube 413 to complete the assembly of the modular power supply component 5.

[0064] In this example, the wiring unit 7 includes a remote control handle 71, a tension sensor 75 installed in the connector unit 1, a controller 74 installed in the control compartment unit 3, a power cord 72 for transmission connection, and a motor control cord 73 connected to the hub motor 51; wherein, the wiring unit 7 is provided with a waterproof layer (not shown in the figure).

[0065] One end of the power cord 72 is connected from the controller 74, pulled out through the side of the cover plate 38, passes through the reserved hole under the control compartment housing 37, enters the middle of the telescopic connecting tube 41, passes through the reserved mounting hole of the battery compartment 521, and is connected to the multi-module outdoor power supply 522 for power supply in the battery compartment 521. The other end of the power cord 72 is connected from the controller 74 and connected to the remote control handle 71.

[0066] The motor control line 73, which is connected from the controller 74, passes through the reserved wire groove under the multi-module outdoor power supply 522, and connects to the hub motor 51 through the reserved mounting hole on the bottom plate of the supporting battery compartment 521 to complete the installation of the control line.

[0067] The remote control handle 71 is equipped with a power switch 711, a forward button 712, and a reverse button 713. The single-point power switch 711 can turn the power of the hub motor 51 on or off. Pressing the forward button 712 will control the hub motor 51 to move forward, and pressing the reverse button 713 will control the hub motor 51 to move backward. Both the forward button 712 and the reverse button 713 have speed settings. Pressing and holding the power switch 711 will inflate the upper inflatable airbag 24 and the lower inflatable airbag 42.

[0068] Overall control line flow: The remote control handle 71 sends a control signal, which is transmitted to the controller 74 via the power line 72. After the controller 74 processes the signal, it transmits the signal to the left and right hub motors 51 via the motor control line 73, respectively, to provide speed signals to the hub motors 51. The hub motors 51 rotate according to the command. At the same time, the hub motors 51 draw power from the multi-module outdoor power supply 522 via the power line 72.

[0069] When the power switch 711 is pressed and held, the remote control 71 sends an inflation signal, which is transmitted to the controller 74 via the power cord 72. The controller 74 processes the signal and then transmits it to the electric air pump 59 via the power cord 72. The electric air pump 59 inflates the upper inflatable airbag 24 and the lower inflatable airbag 42 through the air tube to meet the needs of deep-water swimming.

[0070] The tension sensor 75 is communicatively connected to the controller 74. When the tension sensor 75 transmits the detected waist tension value of the walker to the controller 74 in the form of an electrical signal, the controller 74 controls the assist value of the hub motor 51 according to a preset threshold. During the same gear driving process, it provides assist fine adjustment to match the stride frequency of the person's two feet when walking. The hub motor 51 is equipped with a braking system and locking function (not shown in the figure), which greatly shortens the braking distance when an emergency stop is required and reduces the impact of the vehicle on the human waist.

[0071] In this example, when the walker's walking speed exceeds the vehicle's speed, positive pressure is applied to the tension sensor 75. The controller 74, based on the signal output by the tension sensor 75, controls the hub motor 51 to provide a speed adjustment of 0-0.5 km / h. When an emergency occurs and walking stops, reverse pressure is applied to the tension sensor 75. When the reverse pressure exceeds 100N, the controller 74 detects the signal and sends a command to the hub motor 51 to brake and lock. After the vehicle is locked by the reverse pressure of the tension sensor 75, it moves forward directly. When the positive pressure on the tension sensor 75 reaches 100N while moving forward, the controller 74 detects the signal, and the hub motor 51 returns to the gear and speed before the emergency stop. The controller controls the hub motor 51 to provide a preset assist matching the positive pressure. When an emergency stop occurs, the tension sensor 75 displays reverse pressure, and the controller 74 controls the hub motor 51 to brake and lock. See [link to relevant documentation]. Figure 1 , Figure 8 , Figure 9 .

[0072] It should be noted that the preset values ​​can be adjusted according to usage, and the hub motor can be matched to different needs for off-road and urban driving.

[0073] The second embodiment provided by the present invention, such as Figures 2-10 As shown:

[0075] In this example, the connector unit 1 includes a quick-release connector 11, a cylindrical nut 12, a universal joint 13, a sleeve 14, an elbow 15, and a tension sensor 75 for detecting the tension on the waist is installed inside.

[0076] The elbow joint 15 is made of polyurethane. The elbow joint 15 is inserted into the sleeve 14, and the lower end of the universal joint 13 is inserted into the sleeve 14 to connect with the elbow joint 15. The screw holes on the sleeve 14 are aligned with the screw holes on the universal joint 13 and the elbow joint 15. After passing the mounting screws through, a nut (not shown in the figure) is used for tightening.

The lower ends of the three connecting pipes 23 are respectively fixed to the control chamber unit 3. See [reference needed]. Figure 10 , Figure 3 .

[0079] In this example, the control compartment unit 3 includes a control compartment housing 37, a control compartment cover 38, an angle adjuster 35 installed on the left side wall of the control compartment housing 37 for folding the vehicle, and a rotating shaft 372 installed on the right side wall of the control compartment housing 37. The rotating shaft 372 is movably connected to the central hole 332 of the right side connecting plate 33 installed on the right side of the control compartment housing 37. The upper connecting hole 331 of the right side connecting plate 33 is firmly connected to the connecting hole on the right wall of the connecting plate 32 located on the upper part of the control compartment housing 37 by fasteners. A cylindrical tube 31 connected to the connecting tube unit 2 is fixedly mounted on the connecting plate 32, and a folding handle 311 is fixedly connected between the cylindrical tubes 31 on the connecting plate 32, which serves to stabilize the connecting tube unit 2 and to hold it when folding. A controller 74 is installed inside the control compartment housing 37 and the cylindrical tube 31 fixedly connected to the support tube unit 4 is installed at the bottom of the control compartment housing 37.

Three sliders 353 are respectively placed in the three slots 3511 of the base plate 351, with their bottom surfaces aligned with the outer surface of the rotating spring 352. The outer teeth 3531 of the sliders 353 match and contact the inner teeth 3551 of the cover plate 355 on its inner sidewall. The sliders 353 are provided with protrusions 3532. A limiting plate 354 is installed between the sliders 353 and the cover plate 355. The limiting plate 354 is provided with three elongated... The slide groove 3541 and the protrusion 3532 are inserted into the slide groove 3541. Under the action of force, they can move within the elongated slide groove 3541. The bottom surface of the cover plate 355 is flush with the base plate 351. The outer cover 356 is put on the cover plate 355 to cover the entire part. The adjusting handle 357 is inserted into the center hole of the angle adjuster 35. The square column is inserted into the square holes of the cover plate 355, the limiting plate 354, and the rotating spring 352 in sequence. The cylindrical section at the end is inserted into the cylindrical center hole of the base plate 351 to form a whole.

[0081] The angle adjuster 35 is placed into the housing mounting hole 371 on the left side wall of the control compartment housing 37. It includes a fixing unit and an adjustment unit. The fixing unit includes a base plate 351. The base plate 351 is welded to the angle adjuster connecting plate 36 placed in the installation space 39 and then fixed to the control compartment housing 37 with screws (not shown in the figure), and is fixedly connected to the control compartment housing as a whole. The adjustment unit includes a rotating spring 352, a slider 353, a limiting plate 354, a cover plate 355 and an adjustment handle 357. The cover plate 355 is fixedly connected to the through hole on the left side wall of the connecting plate 32 through the screw hole on the left connecting plate 34 with screws (not shown in the figure).

[0082] Insert the six protruding positioning protrusions 3552 on the surface of the angle adjuster 35 cover plate 355 into the corresponding positioning holes of the left connecting plate 34, and fully weld the joint between the positioning holes and the positioning protrusions 3552; connect the right connecting plate 33 to the right side of the control compartment housing 37 with screws, cover the control compartment cover plate 38 on the control compartment housing 37 and fix it with screws, place the connecting plate 32 between the left connecting plate 34 and the right connecting plate 33, align the threaded holes on both sides of the connecting plate 32 with the threaded holes on the upper end of the left connecting plate 34 and the right connecting plate 33 respectively, and fix them with screws, so that the rear wall of the connecting plate 32 is attached to the rear wall of the control compartment housing 37.

[0083] Three cylindrical tubes 31 are installed on the upper surface of the connecting plate 32, each containing an inner connecting tube 21. Three cylindrical tubes 31 are also installed on the lower surface of the control chamber housing 37, each containing an inner connecting tube 21. The lower ends of the three connecting tubes 23 are inserted into the upper connecting tubes 21 and fixedly connected by fasteners. The three cylindrical tubes 31 with inner connecting tubes 21 installed on the lower surface are fixedly connected to the support tube unit 4 by fasteners. The control chamber housing 37 has through holes (not shown in the figure) for wiring. (See attached diagram.) Figure 4 , Figure 7 , Figure 10 .

[0084] In this example, when folding the vehicle, first remove the connecting screws between the right side connecting plate 33 and the right side of the control compartment housing 37, then turn the adjusting handle 357 to rotate the limiting plate 354. The limiting plate 354 moves the protrusion 3532 through the slide groove 3541, thereby causing the slider 353 to move and retract along the slot 3511 on the base plate 351. At this time, the outer teeth 3531 of the slider 353 on the outside separate from the inner teeth 3551 of the cover plate 355 on the inside, allowing the cover plate 355 to rotate freely. Then, using... By rotating the folding handle 311, the entire machine folds around the control compartment housing 37. When folded to the desired position, the adjusting handle 357 is released. At this time, the rotational expansion of the spring 352 pushes the slider 353 outward along the slot 3511 of the base plate 351, causing the outer teeth 3531 of the slider 353 to re-engage with the inner teeth 3551 of the cover plate 355. At this point, the cover plate 355 and the base plate 351 are relatively fixed and cannot rotate freely, ensuring the folded vehicle is in a stable state. (See also...) Figure 4 , Figure 7 .

[0085] In this example, the support tube unit 4 is made of polyurethane material and includes a telescopic connecting tube 41 and a lower inflatable airbag 42. The telescopic connecting tube 41 has an inner connecting tube 411 and an outer connecting tube 413 that can slide relative to each other, and a support tube 412 passing through them. The support tube 412 is inserted into the inner polyurethane tube 411, and the inner polyurethane tube 411 and the support tube 412 are inserted together into the outer polyurethane tube 413. The outer polyurethane tube 413 and the support tube 412 are fixed together in the cylindrical tube 31 at the top of the battery compartment 521 with screws. The inner polyurethane tube 411 is fixed in the cylindrical tube 31 installed at the bottom of the control compartment housing 37 with screws. The upper end of the soft lower inflatable airbag 42 is fixedly connected to the control compartment unit, and the lower end is fixedly connected to the battery compartment 521, so that the support tube unit 4 can extend and retract within a preset range. When the whole machine is folded, the length can be shortened. See Figure 10 , Figure 5 , Figure 6 .

[0086] In this example, the modular power supply component 5 includes a first support module 52, a modular flexible photovoltaic panel 57 mounted on the first support module 52, a hub motor 51 mounted on the bottom of the first support module 52, and a second support module 6 that is quickly connected to the first support module 52.

[0087] Place the torsion rubber shaft 56 into the square tube at the rear of the battery compartment 521. Slide the square tube sleeve 54 onto the torsion rubber shaft 56 and insert it into the square tube at the rear of the battery compartment, with its surface flush with both ends of the square tube at the rear of the battery compartment 521. Secure it with screws. Connect the connecting rod 53 to the torsion rubber shaft 56 with a flat key (not shown in the figure) and then lock the flat key to the connecting rod 53 with a nut. Insert the hub motor 51 into the lower end hole of the connecting rod 53. On the other side of the connecting rod 53, put the connecting pad 55 onto the shaft of the hub motor 51 and then lock it with a nut. This completes the installation of the hub motor 51. The torsion rubber shaft 56 reduces the vibration of the carrying vehicle. Secure the two parts of the buckle 524 to the battery compartment 521 and battery cover 523 respectively with screws. Place the multi-module outdoor power supply 522 inside the battery compartment 521. An electric air pump 59 is also installed inside the battery compartment 521.

Insert the rotating shaft 571 into the through hole inside the battery compartment 521. Two sections of section 71 are equipped with rotating springs 572. Flexible photovoltaic panels 57 are installed on rotating springs 572. After the battery cover 523 is closed, the buckle 524 is fastened. Ropes 58 are also installed outside the battery compartment 521 to tie the load placed on the upper surface of the battery compartment 521. The multi-module outdoor power supply 522 is equipped with a waterproof layer (not shown in the figure). Three cylindrical tubes 31 are also fixedly installed on the square tube at the rear of the battery compartment 521. The internal connecting tubes 21 are installed inside and fixedly installed with the support tube 412 and the external connecting tube 413 to complete the assembly of the modular power supply component 5.

[0088] The second carrier module 6, serving as a basic combat carrier module that can be quickly connected to the first carrier module 52, includes a stabilizing bracket 61, a stabilizing gimbal bracket 62, and a combat module 63. The stabilizing bracket 61 and the stabilizing gimbal bracket 62 are used to fix and install high-precision camera equipment for reconnaissance, and can also be used to install weapons such as firearms to directly execute combat commands. The combat module 63 includes a carrier compartment 632 and a multi-module outdoor power supply 522 installed inside the carrier compartment 632, as well as a control system 631 for communication with the outside world. The side wall of the carrier compartment 632 is equipped with a buckle 524 that matches the battery compartment 521. The buckle 524 has two separate parts, which can realize the quick installation and removal of the two connected modules. A hub motor 51 is installed at the bottom. The stabilizing bracket 61 and the stabilizing gimbal bracket 62 are installed on the outer surface of the carrier compartment 632 with fasteners.

[0089] In this example, the wiring unit 7 includes a remote control handle 71, a tension sensor 75 installed in the connector unit 1, a controller 74 installed in the control compartment unit 3, a power cord 72 for transmission connection, and a motor control cord 73 connected to the hub motor 51; wherein, the wiring unit 7 is provided with a waterproof layer (not shown in the figure).

[0090] One end of the power cord 72 is connected from the controller 74, pulled out through the side of the cover plate 38, passes through the reserved hole under the control compartment housing 37, enters the middle of the telescopic connecting tube 41, passes through the reserved mounting hole of the battery compartment 521, and is connected to the multi-module outdoor power supply 522 for power supply in the battery compartment 521. The other end of the power cord 72 is connected from the controller 74 and connected to the remote control handle 71.

[0091] The motor control line 73, which is connected from the controller 74, passes through the reserved wire groove under the multi-module outdoor power supply 522, and connects to the hub motor 51 through the reserved mounting hole on the bottom plate of the supporting battery compartment 521 to complete the installation of the control line.

[0092] The remote control handle 71 is equipped with a power switch 711, a forward button 712, and a reverse button 713. The single-point power switch 711 can turn the power of the hub motor 51 on or off. Pressing the forward button 712 will control the hub motor 51 to move forward, and pressing the reverse button 713 will control the hub motor 51 to move backward. Both the forward button 712 and the reverse button 713 have speed settings. Pressing and holding the power switch 711 will inflate the upper inflatable airbag 24 and the lower inflatable airbag 42.

[0093] Overall control line flow: The remote control handle 71 sends a control signal, which is transmitted to the controller 74 via the power line 72. After the controller 74 processes the signal, it transmits the signal to the left and right hub motors 51 via the motor control line 73, respectively, to provide speed signals to the hub motors 51. The hub motors 51 rotate according to the command. At the same time, the hub motors 51 draw power from the multi-module outdoor power supply 522 via the power line 72.

[0094] When the power switch 711 is pressed and held, the remote control 71 sends an inflation signal, which is transmitted to the controller 74 via the power cord 72. The controller 74 processes the signal and then transmits it to the electric air pump 59 via the power cord 72. The electric air pump 59 inflates the upper inflatable airbag 24 and the lower inflatable airbag 42 through the air tube to meet the needs of deep-water swimming.

[0095] The tension sensor 75 is communicatively connected to the controller 74. When the tension sensor 75 transmits the detected waist tension value of the walker to the controller 74 in the form of an electrical signal, the controller 74 controls the assist value of the hub motor 51 according to a preset threshold. During the same gear driving process, it provides assist fine adjustment to match the stride frequency of the person's two feet when walking. The hub motor 51 is equipped with a braking system and locking function (not shown in the figure), which greatly shortens the braking distance when an emergency stop is required and reduces the impact of the vehicle on the human waist.

[0096] In this example, when the walker's walking speed exceeds the vehicle's speed, positive pressure is applied to the tension sensor 75. The controller 74, based on the signal output from the tension sensor 75, controls the hub motor 51 to provide a speed adjustment of 0-0.5 km / h. When an emergency occurs and walking stops, reverse pressure is applied to the tension sensor 75. When the reverse pressure exceeds 100N, the controller 74 detects the signal and sends a command to the hub motor 51 to brake and lock. After the vehicle is locked by the reverse pressure of the tension sensor 75, it moves forward directly. When the positive pressure on the tension sensor 75 reaches 100N while moving forward, the controller 74 detects the signal, and the hub motor 51 returns to the gear and speed before the emergency stop. The controller controls the hub motor 51 to provide a preset assist matching the positive pressure. When walking stops in an emergency, the tension sensor 75 displays reverse pressure, and the controller 74 controls the hub motor 51 to brake and lock. (See figure). Figure 8 , Figure 9 , Figure 10 .

[0097] It should be noted that the preset values ​​can be adjusted according to usage, and the hub motor can be matched to different needs for off-road and urban driving.

[0098] It should be noted that the number of carrier modules can be set as needed, and they can be connected together to realize carrier and corresponding operation functions.
