Description

Technical Field

[0001] The present invention relates to the technical field of telescopic equipment, and in particular to a vector thrust assisted telescopic device. Background Art

[0002] Frequent cleaning is required for commercial buildings, high-end residential lobby facade glass, columns, basement facades, urban street-facing commercial buildings, villas, exterior windows of low-rise residential buildings, facades of public facilities such as airports, railway stations, and stadiums, canopies and billboards of gas stations, facades of industrial plants, industrial facilities including large liquid and gas storage tanks, large outdoor chemical equipment, and ship facades.

[0003] These work locations are typically less than 20 meters high, making conventional masts insufficient. Using a Spider-Man sling for cleaning is inefficient and costly. Using mechanical lifting devices like ladders, combined with manual labor, is expensive and burdensome, as is transporting the heavy equipment between different work locations. Both of these solutions are costly, making cleaning in these locations difficult to implement.

[0004] In addition, urban municipal facilities, such as lamp poles, lighting fixtures, road signs, tunnel walls and ceilings, subway station facades and underground station walls and ceilings; in agricultural and municipal greening applications, high-altitude branch pruning and fruit picking; in photovoltaic power generation, the cleaning of large-scale photovoltaic panels also requires low-cost long-range cleaning solutions.

[0005] At present, for all the above-mentioned application scenarios, there is only one way, both domestically and internationally, to achieve lifting or extending the pole on the ground by connecting an extension pole. This simple method of connecting and extending the working pole faces the basic mechanical model in which the center of gravity of the pole is far away from the operator, and the outer end of the pole forms a very large torque relative to the operator's end. As a result, even if the outer end has only a small weight or a small external operating force, after being amplified by the torque of the long pole, the torque at the operator's end far exceeds the limit of the operator's physical strength. In layman's terms, the long pole cannot be lifted and cannot be used. In fact, the actual operating distance of the pole is usually within 7 meters. If it is too long, the outer end of the pole will cause serious deformation or even breakage, and effective operation will be impossible. Therefore, this length is far from meeting the needs of the above-mentioned operating scenarios. Summary of the Invention

After the spiral blade rotates at high speed, it can provide an upward thrust for the vector thrust unit, and the thrust can at least overcome part of the weight of the vector thrust unit and the rod unit.

[0018] On the basis of the above technical solution, in order to improve the operating efficiency and stability of the vector thrust unit, the crossbeam and the rod unit are arranged perpendicularly.

[0019] On the basis of the above technical solution, in order to improve the safety of the product and avoid unnecessary additional contact when the spiral blade rotates at high speed, a protective frame is provided on the periphery of the spiral blade of the driving member, and the protective frame is connected and fixed to the crossbeam.

[0022] On the basis of the above technical solution, in order to prevent the crossbeam from excessively rotating and causing interference between structures, the pivot unit is further provided with a limiting structure for limiting the rotation stroke of the rotating shaft.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0040] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Example 1:

[0044] See also Figure 1 This embodiment discloses a vector thrust assisted reaching device, which includes a rod unit 100, an operating unit 600, a vector thrust unit 200, a pivot unit 300 and a control unit 400.

[0045] Specifically, the rod unit 100 is composed of a carbon fiber tube with a length of 10 meters. One end of the rod unit 100 is used for the user to grasp and operate, and the other end is used to connect the operating unit 600 to operate the operating area. In this embodiment, the operating unit 600 uses a detachable brush for cleaning scenes such as building exterior walls.

[0046] The vector thrust unit 200 is movably connected to the rod unit 100 and is provided with two thrust drive mechanisms of controllable size. The thrust generated by the thrust drive mechanisms can overcome the weight of the vector thrust unit 200 itself and part of the weight of the rod unit 100.

[0047] Specific, combined Figure 2 As shown, the vector thrust unit 200 includes two thrust drive mechanisms arranged in a group, each of which includes a crossbeam 201 and a drive member. The crossbeam 201 is used to connect the two spaced apart drive members, acting as a connecting load. The drive member is an electric propeller with the propeller blades facing downward. After high-speed rotation, the propeller provides an upward thrust to the vector thrust unit 200, which can overcome at least part of the weight of the vector thrust unit 200 and the rod unit 100.

[0048] Furthermore, the crossbeam 201 is fixedly connected to the rod unit 100 and is in transmission connection with the pivot unit 300 so as to be able to pivot. Its pivoting movement enables the driving member to swing on the axial plane of the rod unit 100, that is, its pivoting movement enables the driving member to swing longitudinally (in the pitch angle direction of the rod unit 100).

[0049] In this embodiment, Figure 2 As shown, the drive components consist of propeller motors 202, propeller blades 203, a protective frame 205, and propeller ESCs 206. The two propeller motors 202 are secured to the left and right ends of the crossbeam 201 via first fixings 204, which are locking kits. The two propeller ESCs 206 are secured to the crossbeam 201 near the first fixings 204 and connected to the power cables of the propeller motors 202 to control their drive speed.

[0050] Two centrally symmetrical propeller blades 203 are provided at the output end of each propeller motor 202. The propeller motor 202 can drive the propeller blades 203 to rotate in a directional high-speed manner, so that the propeller blades 203 generate downward blowing during the rotation process to form a reverse upward thrust. This thrust is the vector thrust (support force) used to overcome the weight of the vector thrust unit 200 itself and part of the weight of the rod unit 100.

[0051] Furthermore, to enhance product safety and prevent unnecessary contact with the propeller blades during high-speed rotation, a protective frame 205 is provided around the periphery of the propeller blades 203. The protective frame 205 is connected and secured to the end of the crossbeam 201 via a support rod 207 and a second fixing member 209. The support rod 207 ensures that the structure of the protective frame 205 remains stationary. To ensure that the vector thrust unit 200 can be placed stably when idle, a support structure is provided at the bottom of the protective frame 205. Specifically, the support structure comprises a support column 208 disposed at the bottom of the support column 207. The support column 208 is vertically disposed. When idle or after the vector thrust unit 200 is disassembled, the bottom end of the support column 208 can be used to abut against the ground for support, thereby ensuring that the entire vector thrust unit 200 can be placed stably on the ground.

[0052] In order to improve the operating efficiency and stability of the vector thrust unit 200, the beam 201 is arranged vertically to the rod unit 100, that is, the beam 201 is in a horizontal state after assembly, and together with the rod unit 100 forms an operating plane, and the two driving members are symmetrically arranged at the left and right ends of the beam 201. The beam 201 can connect the two driving members to form a whole, and the horizontal layout extension of the beam 201 can extend the operating areas of the two driving members outward and separate them, thereby improving the balance and controllability of the operating plane.

[0053] In order to reduce the weight burden, the crossbeam 201 and the protective frame 205 both adopt a hollow tube structure.

[0054] The pivot unit 300 is disposed between the vector thrust unit 200 and the rod unit 100 , so that the vector thrust unit 200 can change its assembly angle relative to the rod unit 100 .

[0055] like Figure 3 As shown, to increase the precision and controllability of the vector thrust output direction, the pivot unit 300 includes a rotating shaft 303, which is fixedly connected to the rod unit 100 via a third fixing member 301. One axial end of the rotating shaft 303 is drivingly connected to a pivot drive member. In this embodiment, the pivot drive member is a pivot motor 304, which can directly drive the rotating shaft 303 to rotate. One radial end of the rotating shaft 303 is connected to the crossbeam 201 via a fourth fixing member 302. After assembly, the crossbeam 201 is perpendicular to the rod unit 100. The pivot motor 304 can drive the rotating shaft 303 to rotate the crossbeam 201 in a transverse plane, causing the vector thrust direction to swing in the pitch angle direction of the rod unit 100.

[0056] Furthermore, in order to prevent the crossbeam 201 from excessively rotating and causing interference between structures, the pivot unit is also provided with a limiting structure for limiting the rotational travel of the rotating shaft 303. In this embodiment, the limiting structure is specifically a limiting claw 306 arranged on the radial side of the third fixing member 301.

[0057] A posture sensor 305 is installed on one side of the third fixing frame to accurately and in real time detect the working status of the vector thrust unit 200, such as real-time monitoring of the lateral rotation, pitch, and heading angle parameters of the crossbeam 201. The posture sensor 305 is connected to the control unit 400.

[0058] The control unit 400 includes a communication module, a power module, and a data processing module. The communication module is used to receive remote control signals and provide operational status feedback. The power module, specifically a dry cell or liquid battery, provides power. The data processing module receives and processes sensor signals and remote control signals, generates corresponding operational instructions, and feeds them back to the corresponding components. These modules are integrated into a housing and fixedly mounted on the rod unit 100. These modules are all conventional, and their specific structures and the operating principles underlying their operation are not further described here.

[0059] In this embodiment, in order to prevent the cables from becoming messy, fixing clips are provided along the distribution paths of the cables on the rod unit 100 .

[0060] In order to facilitate operation and flexibly control the components of the equipment, the device also includes a remote control unit 500, which is arranged at the end of the rod unit 100 away from the operating unit 600. The remote control unit 500 is used for the user to operate and control the driving components. The remote control unit 500 includes a display screen and buttons for human-computer interaction.

[0061] The driving components located on both sides of the crossbeam 201 are respectively a first propeller a1 and a second propeller a2.

[0062] Combine Figure 4 During operation, the first propeller a1 generates a downward wind force F1, and the reaction force of F1 is an upward F1'. The second propeller a2 generates a downward wind force F2, and the reaction force of F2 is an upward F2'. When F1 and F2 are symmetrical in direction and of equal magnitude, the resultant force of F1 and F2 is a vertically downward Ftotal. Therefore, the vector thrust unit 200 receives a vertically upward reaction force Ftotal' in the opposite direction to Ftotal. In this state, only a longitudinally upward auxiliary thrust is generated. This auxiliary thrust can help the vector thrust unit 200 and the rod unit 100 provide longitudinal support to maintain longitudinal posture stability or actively perform longitudinal (pitch angle direction of the rod unit 100) movement, thereby realizing movement control of the rod unit 100 in the pitch angle.

[0063] Combine Figure 5 During operation, when the wind force F2 generated by the second propeller a2 is greater than the wind force F1 generated by the first propeller a1, that is, the reaction force F2' of F2 is greater than the reaction force F1' of F1, the resultant force of F1 and F2 is Fcombined, which is offset to one side in the horizontal direction (the direction of Fcombined in the figure is toward the lower right). Therefore, the vector thrust unit 200 obtains a reaction force Fcombined' that is opposite to the direction of Fcombined and tilted upward (the direction of Fcombined' in the figure is toward the upper left). In this state, not only a longitudinal upward auxiliary thrust is generated, but also a horizontal deflection force is generated due to the restriction of the connection point between the beam 201 and the rod unit 11 (in this embodiment, the connection point is located in the middle of the beam 201). Combined with Figure 6 As shown, the reaction force F2' generated by the second propeller a2 is decomposed into F2'x and F2'y in the horizontal and vertical directions, respectively. The reaction force F1' generated by the first propeller a1 is decomposed into F1'x and F1'y in the horizontal and vertical directions, respectively. In this state, F2'x is greater than F1'x, and the difference between the two constitutes the aforementioned horizontal deflection force. Therefore, the reaction force F2' corresponding to F2' not only helps the rod unit 100 achieve lifting / lowering control capabilities, but also enables the rod unit 100 to achieve rod pointing control capabilities, that is, it can simultaneously control the pitch angle and yaw angle of the rod unit 100. In practice, this structure coordinates the driving force of the first and second propellers a1 and a2, and the active control of the pivot unit 300, to actively control the simultaneous pitch and yaw angles of the rod unit 100. Furthermore, through the operator's control, the roll angle (the axial rotational direction of the rod unit 100) can be easily controlled. This ensures that when the rod unit 100 is extended and raised, the working plane is able to withstand crosswinds and will not be overturned by crosswinds, thus ensuring the safety of the lifting operation.

[0064] Further, combined Figure 7 When the pivoting unit 300 actively adjusts the angle of the crossbeam 201, the crossbeam 201 drives the entire vector thrust unit 200 to swing longitudinally. This swinging change affects the direction of the wind force Fwind generated by the propeller, thereby actively adjusting the direction of the resulting Fthrust. This structure allows the rod unit 100 to be raised and lowered according to the operator's intention, and also provides additional operating force at the far end of the rod unit 100.

[0065] Therefore, by synchronously adjusting the speed of the two propellers, adjusting the speed difference of the two propellers, and actively adjusting the angle of the beam 201 and the vector thrust unit 200 using the pivot unit 300, thrust changes with different effects can be obtained, and the operation control can be performed independently or collaboratively to obtain different expected effects.

[0066] like Figure 8 As shown, through experimental tests, the angle between the two blade rotation planes of the first propeller a1 and the second propeller a2 is preferably 120 degrees to 170 degrees.

[0067] In the specific implementation process, if the vector thrust is output in the radial direction of the rod (such as Figure 4 As shown), if it is perpendicular to the ground, it can share the weight of the pole with the operator and independently bear the weight of the working unit 600. According to the control instructions of the operator, the radial thrust can be increased or decreased to lift or lower the pole. The vector thrust carries part or most of the weight of the pole, which not only eliminates the torque amplification effect caused by the center of gravity of the pole being far away from the operator, but also allows the operator to easily lift a pole extended to 20 or 30 meters off the ground. At the same time, it keeps outputting during the operation to load the weight of the pole, greatly reducing the labor intensity of the operator.

[0068] The vector thrust is located in the radial output plane of the shaft. When it rotates around the radial axis of the shaft, it forms an angle with the direction of gravity, generating a horizontal component perpendicular to the direction of gravity. When this component is directed toward the working surface, it can achieve the desired working force during outreach operations, such as downward pressure against the wall. When this component is directed toward the left and right sides, it can be used to resist lateral winds, keeping the working plane stable.

[0069] The vector thrust unit 200 cooperates with the extension operation of the rod unit 100 to solve the problem that the traditional rod cannot be lifted or exerted after being extended, making it possible to cover low-altitude operations at low cost.

[0070] Example 2:

[0071] Based on Example 1, when the length of the rod unit 100 exceeds 15 meters, a single vector thrust unit 200 may not be able to match the weight support of the rod. Figure 9 As shown, two sets of vector thrust units 200 are provided for adaptation to meet the operational requirements.

[0072] In other embodiments, the driving member may also be an electric ducted fan.

[0073] In other embodiments, the working unit 600 may be a tool structure such as a saw, electric scissors, an electric saw blade, a wiper, etc.

[0074] In other embodiments, in order to flexibly adapt to the height requirements in different working scenarios, the rod unit 100 has a rod structure with adjustable length. Specifically, the rod unit 100 can adopt a structure with multiple rods plugged into each other or a telescopic rod structure.

[0075] In other embodiments, a camera module may be further provided on the operation unit 600 for real-time observation or video recording of the specific scene in the operation area.

[0076] In other embodiments, the remote control unit 500 may also adopt a detachable structure, which can be removed from the rod unit 100 and then fixed on the operator's arm using a wearable structure. An intelligent sensing system can even be set up to identify the operator's operating intentions, such as lifting, lowering, rotation direction, etc. The operator can also manually control the output of operating instructions through a physical crank handle, and the remote control device transmits the control instructions to the target drive component wirelessly or via a signal line for operation.

[0077] In other embodiments, the power supply can be connected to an external mains power supply using cables and transformer elements to provide basic energy security for long-term operations.

[0078] In other embodiments, the third fixing member 301 may also adopt a hinged structure, so that the crossbeam 201 can rotate relative to the rod unit 100, and the rotation direction is located in the radial plane of the rod unit 100. A rotation drive structure compatible with the third fixing member 301 can also be added for active rotation control.

[0079] In other embodiments, the propeller may also be connected to the crossbeam 201 using a universal connection structure and a wind direction control system, so that the controllability of the rod unit 100 is more diversified and high-precision.

[0080] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
