[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0036] like Figure 1 As shown, an embodiment of the present invention provides an electric individual-assisted transport system, which includes: a waist fixing component 1, a vehicle body 2 and a transport control component, wherein the waist fixing component 1 can be worn on the user's waist, the vehicle body 2 includes a multi-directional connection mechanism 4, an elastic damping mechanism 6, a folding mechanism 7, a lightweight flexible load-bearing vehicle body 9 and a drive assembly 10 arranged in sequence, the vehicle body 2 is connected to the waist fixing component 1 through the multi-directional connection mechanism 4, the folding mechanism 7 is used to realize the folding and unfolding of the vehicle body 2, the drive assembly 10 is arranged at the bottom of the lightweight flexible load-bearing vehicle body 9, and is used to drive the vehicle body 2 to move, the transport control component includes a control signal acquisition unit and a controller 8, the controller 8 is integrated in the folding mechanism 7, and the control signal acquisition unit is used to input a control signal to the controller 8 so that the controller 8 controls the movement of the vehicle body 2.

[0037] Furthermore, the multi-directional connection mechanism 4 is located at the front of the vehicle body 2, specifically, as Figure 2 As shown, the multi-directional connection mechanism 4 includes an embedded end 41 and a universal joint 42. Specifically, the embedded end 41 is located at the front side of the multi-directional connection mechanism 4 and can be inserted into the waist fixing device 1; the universal joint 2 is located at the rear side of the multi-directional connection mechanism 4, connected with the tension and compression sensor 5 and the elastic damping mechanism 6, and is used to adjust the deflection angle and / or travel direction of the vehicle body 2, so as to meet the power transmission, adapt to the steering and the angle change of the vehicle body 2 without affecting the user's actions. It can be seen that during the travel process, the user can use the multi-directional connection mechanism 4 located at the front end of the carrier system to complete the steering, quick detachment and reset of the carrier system.

[0038] Furthermore, the lightweight flexible load-bearing body 9 is connected to the lower end of the folding mechanism 7, specifically, as Figure 2As shown, the lightweight flexible load-bearing vehicle body 9 includes a strap 91 and a flexible support frame 92 for the vehicle body, wherein the flexible support frame 92 for the vehicle body is used to bear the load of the transport system, and the strap 91 is used to fix the load; wherein the strap 901 can be made of nylon, for example, and the flexible support frame 902 for the vehicle body can be made of aluminum alloy, for example. It should be noted that the present invention does not specifically limit the material, shape, etc. of the strap 91 and the flexible support frame 92 for the vehicle body.

[0039] During work, the user wears the waist fixing component 1 and fixes the load to be carried on the lightweight flexible load-bearing vehicle body 9; then, the user operates the folding mechanism 7 to unfold the vehicle body 2, connects the waist fixing component 1 and the vehicle body 2 through the multi-directional connection mechanism 4, and inputs a control signal to the controller 8 integrated in the folding mechanism 7 via the control signal acquisition unit (handheld wireless remote control 3 and / or tension and compression sensor 5), so as to control the movement of the transport system; and then uses the drive assembly to provide electrical energy to drive the transport system; after use, the folding mechanism 7 is operated to fold the vehicle body 2 to save storage space.

[0040] Therefore, compared with the prior art, the multi-directional connection mechanism is connected to the waist fixing component worn on the user's waist, which can free up the user's load-bearing capacity. Most of the load originally on the back is transferred to the carrying system, which significantly improves the user's mobility, frees up the user's hands and back carrying space, and provides additional carrying capacity; the control signal input by the control signal acquisition unit is transmitted to the controller to control the movement of the vehicle body; the driving assembly provides electrical energy to drive the carrying system to move; the lightweight and flexible load-bearing body can enhance the shock absorption and side slope balance capabilities of the carrying system under complex road conditions; the folding mechanism can realize the rapid folding and unfolding of the vehicle body, which is convenient and quick.

[0041] Furthermore, the elastic damping mechanism 6 is located at the front of the vehicle body 2, and is used to realize the connection between the multi-directional connection mechanism 4 and the vehicle body 2, so as to provide elastic buffering between the user and the vehicle body 2, thereby stabilizing the overall traveling state of the transport system. One end of the elastic damping mechanism 6 is connected to the tension and compression sensor 5 and the multi-directional connection mechanism 4, and the other end is installed on the folding mechanism 7. Specifically, Figure 3As shown, the elastic damping mechanism 6 includes a fixed bracket 64 and a first elastic damping rod 61, a second elastic damping rod 62 and a third elastic damping rod 63 arranged on the fixed bracket 64, wherein the first elastic damping rod 61 and the third elastic damping rod 63 are arranged on both sides of the second elastic damping rod 62. Specifically, the first elastic damping rod 61 and the second elastic damping rod 62 include straight rods, and the third elastic damping rod 63 includes an arc-shaped pre-bent rod to absorb the vibration generated by the electric single-soldier power-assisted transport system during the travel process and play a buffering role. During operation, the first elastic damping rod 61, the second elastic damping rod 62 and the third elastic damping rod 63 absorb the stress between the user and the transport system to alleviate the change in the posture of the vehicle body 2, ensure the coordinated stability of the travel posture of the transport system, and prevent the vehicle body 2 from rolling over. In addition, in an emergency, when the user detaches the vehicle body 2 through the waist fixing assembly 1, the first elastic damping rod 61, the second elastic damping rod 62 and the third elastic damping rod 63 can absorb the impact force of the vehicle body 2 when it is unlocked and falls to the ground, so as to protect the structure and components on the vehicle body 2.

[0042] Furthermore, the material used by the first elastic damping rod 61, the second elastic damping rod 62 and the third elastic damping rod 63 includes polyurethane, which is light in weight and has a tough structure. It should be noted that the first elastic damping rod 61, the second elastic damping rod 62 and the third elastic damping rod 63 of the present invention can also be made of other polymer materials, such as polyethylene.

[0043] Furthermore, if Figure 1 As shown, the drive assembly 10 includes a power battery pack 11 and two drive wheels 12. The power battery pack 11 is arranged at the bottom of the lightweight flexible load-bearing body 9, and the two drive wheels 12 are respectively arranged on both sides of the bottom of the lightweight flexible load-bearing body 9 to support and drive the transport system. The electric single-soldier power-assisted transport system of the present invention is powered by the power battery pack 11 installed at the bottom of the vehicle body 2 to supply energy to the drive wheels 12 distributed on both sides of the vehicle body 2 to drive the movement of the vehicle body 2.

[0044] Furthermore, if Figure 4As shown, each of the driving wheels 12 includes a hub motor 121, an all-terrain tire 122 and an axle shock absorber assembly 123, wherein the hub motor 121 is integrated in the hub of the all-terrain tire 122, and the axle shock absorber assembly 123 is arranged on the inner side of the bottom of the vehicle body 2 and connected to the lightweight flexible load-bearing vehicle body 9, specifically, connected to the vehicle body flexible support frame 92 of the lightweight flexible load-bearing vehicle body 9, for absorbing the vibration generated by the electric single-soldier power-assisted transport system during travel, thereby providing a buffering and protective effect on the transport system. The axle shock absorber assembly 123 is an independent suspension system, and the all-terrain tires 122 and shock-absorbing springs on both sides of the suspension can move up and down independently. The present invention has the characteristics of low noise and low thermal characteristics by adopting an independent suspension shock-absorbing drive assembly 10, and can provide high torque output in all speed modes, which meets the requirements of military equipment for static operation and concealment.

[0045] According to the foregoing description, the electric single-soldier power-assisted transport system of the present invention can achieve the effect of shock absorption and stabilization through the universal joint 42, the elastic damping mechanism 6, the vehicle body flexible support frame 92, the all-terrain tire 122 and the wheel axle shock absorber assembly 123. Specifically, by absorbing and buffering the vibration and deformation generated by the transport system during use, the user and the transport system are stabilized in their travel state, and two-way protection between the user and the vehicle body 2 is achieved. Furthermore, the present invention strengthens the shock absorption and buffering and side slope balancing capabilities of the transport system under complex road conditions through the first elastic damping rod 61, the second elastic damping rod 62 and the third elastic damping rod 6 located in the middle of the vehicle body flexible support frame 92 and the wheel axle shock absorber assembly 123 at the bottom of the vehicle body and serving as an independent suspension shock absorber, ensuring stable driving and no rollover during travel on rugged terrain, while minimizing the impact of the carried load on the user's travel movements.

[0046] The control signal acquisition unit includes a handheld wireless remote controller 3 and / or a tension-compression sensor 5, wherein the tension-compression sensor 5 is arranged between the multi-directional connection mechanism 4 and the elastic damping mechanism 6. In one implementation of the present invention, the control signal acquisition unit only includes the handheld wireless remote controller 3; in another implementation of the present invention, the control signal acquisition unit only includes the tension-compression sensor 5; in yet another implementation of the present invention, the control signal acquisition unit includes both the handheld wireless remote controller 3 and the tension-compression sensor 5, and the present invention does not specifically limit this.

[0047] After the electric single-soldier power-assisted transport system of the present invention is turned on and initialized for self-check, it enters the main cycle operation process, and the controller 8 continuously monitors the position of the switch of the handheld wireless remote controller 3, the working state of the charging system, the battery power, the battery temperature and the short circuit. When the pre-set shutdown conditions appear, including the switch is in the shutdown position, the charging system is in the working state, the battery power is too low, the battery temperature is too high, the system has a short circuit, etc., the system will automatically enter the shutdown program to minimize the system operation risk and protect the user and the transport system. At the same time, the controller 8 will control the output of the hub motor 121 in real time according to the control signal input by the user through the handheld wireless remote controller 3 or the tension and compression sensor 5.

[0048] Specifically, in one implementation of the present invention, the controller 8 adopts a wireless remote control mode, the handheld wireless remote controller 3 is electrically connected to the controller 8, and is used to allow the user to input a remote control signal, and send the remote control signal to the controller 8 via wireless communication. The controller 8 is used to continuously receive the remote control signal, and convert the remote control signal into a preset corresponding motor output setting parameter, and compare it with the actual output parameter of the hub motor 121, and adjust the operating state of the hub motor 121 according to the comparison result, so that the actual output of the hub motor 121 is consistent with the remote control signal input by the user, and the output control of the hub motor 121 is realized. The user can control the forward movement, braking, acceleration uphill, steep slope descent, etc. of the electric single-soldier power-assisted transport system through the handheld wireless remote controller 3. The control signal is transmitted to the controller 8 located in the middle of the transport system via the handheld wireless remote controller 3, and then the power battery pack 11 built into the bottom of the frame provides power to the hub motors 121 on both sides of the 92-body flexible support frame to drive the transport system to move.

[0049] In another implementation of the present invention, the controller 8 adopts an automatic following mode, and the tension and compression sensor 5 is electrically connected to the controller 8. Figure 2 and Figure 3 As shown, the tension and compression sensor 5 is connected to the universal joint 42 in the multi-directional connection mechanism 4, and is used to transmit the tension and compression deformation caused by the traction force caused by the change of the relative motion state between the user and the vehicle body 2 to the controller 8 in the form of a tension and compression sensing electrical signal. The controller 8 is used to continuously receive the tension and compression sensing electrical signal, and compare the tension and compression sensing electrical signal with a preset tension and compression sensing electrical signal value range. When the actual tension and compression sensing electrical signal exceeds the preset electrical signal value range, the operating state of the hub motor 121 is adjusted according to the actual tension and compression sensing electrical signal, so that the tension and compression sensing electrical signal returns to the preset tension and compression sensing electrical signal value range, even if the traveling state of the transport system meets the needs of the user, thereby realizing output control of the hub motor 121.

[0050] Specifically, in the automatic following mode, the output signal of the tension and compression sensor 5 is set to x, and the control program of the controller 8 is provided with three ranges of x: x<a, a≤x≤b, b<x; among them, when a≤x≤b, the traveling states of the vehicle and the person are basically the same, the deformation of the tension and compression sensor 5 is very small and can be ignored, and there is no need to adjust the working state of the drive assembly 10; when x<a, the tension and compression sensor 5 generates a signal due to the inconsistency between the traveling states of the person and the vehicle, and the user's traveling speed is slower than the carrying system. A certain amount of compression will cause the output signal x to decrease, so the working state of the driving assembly 10 needs to be adjusted to slow down the transport system and restore it to a state consistent with the vehicle, that is, to a≤x≤b; similarly, when b<x, the tension-compression sensor 5 will produce a certain amount of stretching due to the inconsistency between the vehicle and the human, and the user's travel speed is faster than the transport system, and the output signal x becomes larger, so the working state of the driving assembly 10 needs to be adjusted to accelerate the transport system to keep it consistent with the user's travel speed, that is, to restore it to a≤x≤b.

[0051] It can be seen that during the process of traveling, the electric single-soldier power-assisted transport system of the present invention has two control modes: wireless remote control type and automatic following type. Among them, in the wireless remote control mode, the user adjusts the running state of the hub motor 121 through the speed control knob on the handheld wireless remote controller 3, thereby realizing the control of the travel state of the transport system. Therefore, the user can adjust the travel state of the transport system in real time through the handheld wireless remote controller 3 according to his own needs; in the automatic following mode, the controller 8 senses and measures the position change, relative distance and speed difference between the user and the transport system in real time through the tension and compression sensor 5 located at the front end of the system, thereby adjusting the output of the hub motor 121 to keep the travel speed of the transport system consistent with that of the user. Therefore, the user does not need to control the transport system. The controller 8 will monitor the user's movement state in real time according to the tension and compression sensor 5, and adjust the output of the hub motor 121 accordingly, thereby realizing intelligent following and liberating the user's hands. Furthermore, during the uphill process, the user can adjust the operating state of the carrying system to increase the output power and torque of the hub motor 121 to help accelerate the uphill journey; during the downhill process, the user can adjust the operating state of the carrying system to limit the output power and torque of the hub motor 121 to ensure that the carrying system always moves at the same speed as the user, thereby minimizing the impact and risk of the carried weight on the user's moving movements when going downhill.

[0052] After the electric individual-assisted transport system of the present invention enters the shutdown procedure, the transport system will terminate the output of the motor and the battery in turn, and shut down the transport system after a second confirmation.

[0053] The electric individual-assisted transport system provided in the embodiment of the present invention is connected to a waist fixing assembly worn on the user's waist through a multi-directional connection mechanism, which can liberate the user's load-bearing capacity. Most of the load originally on the back is transferred to the transport system, which significantly improves the user's mobility, liberates the user's hands and back carrying space, and provides additional carrying capacity; the control signal input by the control signal acquisition unit is transmitted to the controller to control the movement of the vehicle body; the electric energy provided by the drive assembly can drive the transport system to move; the lightweight and flexible load-bearing vehicle body can enhance the shock absorption and side slope balance capabilities of the transport system under complex road conditions; the folding mechanism can realize the rapid folding and unfolding of the vehicle body, which is convenient and quick.
