Description

Technical Field

[0001] The present invention belongs to the technical field of lawn mowers, and in particular relates to a lawn mower equipped with a modular intelligent vehicle. Background Art

[0002] Lawn mowers are machines used in fields such as courtyards, gardens, and agriculture to trim or remove grass or dead wood on the ground according to actual needs. With the rapid development of municipal gardens, photovoltaic power stations, and orchards in my country, the demand for mowing is growing. Due to the vast territory and different planting habits in different places, high requirements are placed on the flexibility, high reliability, and applicability of the machine.

[0003] Most of the existing garden machinery is of step-by-step or riding type, with a bulky structure, inflexible steering, and requires an experienced driver to operate. It is expensive and inconvenient to operate; the handheld type is noisy and labor-intensive, which is harmful to the operator; the garden mostly uses a crawler chassis + disc knife type, which has the problem of unclean grass cutting under the chassis, and one machine is only suitable for one cutting width. Different widths require the whole machine to be switched and the cutting width is limited by the maximum disc diameter, which is inefficient and has poor adaptability to different planting habits; most agricultural machinery uses the structure of a field return machine and hammer cutting, which has high power consumption, a bulky vehicle, poor passability, a high center of gravity, and is easy to overturn when climbing slopes and obstacles, and there are major safety hazards in complex road conditions.

[0004] For example, the Chinese utility model patent with application number 202120719909.8 discloses a lawn mower, including: a main body; a mowing module, the mowing module is detachably connected to the main body as a whole, and is electrically connected to the main body. In this solution, the mowing module adopts a modular design, which facilitates the replacement, maintenance and disassembly of the mowing module, and improves the efficiency of replacement and maintenance.

[0005] For another example, the Chinese invention patent with application number 202610137987.7 discloses a riding lawn mower, comprising a lawn mower frame for carrying passengers and a cutting unit connected to the frame, wherein the cutting unit has at least one rotatably mounted blade. Each interchangeable power unit support assembly supports an engine or battery unit connected to a generator, so that the power unit can be replaced.

[0060] See also Figure 19-Figure 23 The present invention provides an independent quick-detachable cutting platform for a lawn mower, such as Fig.19 , including a cutting panel 1, a connecting bracket 4 and a height adjustment module 7, the cutting panel 1 is respectively provided with a cutting disc 6 and a second control module 108 for controlling the operation of the cutting disc.

[0061] Among them, the cutting panel serves as the main frame of the cutting platform and is used to carry other components. One end of the connecting bracket is connected to the upper surface of the cutting panel through a bolt assembly, and the other end is connected to the connecting assembly of the lawn mower through a locking pin. The cutting disc is assembled on the cutting panel. During implementation, different numbers of cutting discs can be arranged at different positions according to the width and use conditions of the cutting panel, so as to realize the function of chopping stems within the width. One end of the height adjustment bracket is hinged to the cutting panel through a rotating sleeve, and the other end is connected to the cutting panel through a quick latch. Different heights of the cutting panel above the ground can be achieved through different pin positions thereon.

The above components work together to achieve high-quality and silent mowing on the cutting platform, and replacement and maintenance are convenient and quick, and the expansibility and adaptability are strong.

[0062] Specifically, Fig.21 , the first end of the connecting bracket 4 is fixedly connected to the upper surface of the cutting panel 1, and the second end of the connecting bracket 4 is detachably connected to the connecting component of the lawn mower, wherein the connecting component is respectively provided with a first mounting hole 213 and a second mounting hole 214, and the second end of the connecting bracket 4 is provided with a third mounting hole 41 cooperating with the first mounting hole 213, and at least two fourth mounting holes 42 of different heights cooperating with the second mounting hole 214;

[0063] When the first fixing member 51 is passed through the first mounting hole 213 and the third mounting hole 41, or the second fixing member 52 is passed through the second mounting hole 214 and one of the fourth mounting holes 42, the connecting bracket 4 can rotate relative to the connecting component; when the first fixing member 51 is passed through the first mounting hole 213 and the third mounting hole 41, and the second fixing member 52 is passed through the second mounting hole 214 and the fourth mounting hole 42, the first fixing member 51 cooperates with the second fixing member 52 to fix the connecting bracket and the connecting component.

[0064] In some embodiments, a length-adjustable connection chain 43 is provided on the connection bracket, one end of the connection chain 43 is fixed to the connection bracket 4, and the other end is detachably connected to an elastic member (preferably a spring) of the connection assembly.

[0065] In some embodiments, two connecting brackets are provided, and the two connecting brackets are connected and fixed on the cutting panel via an intermediate bracket 44 .

[0066] like Fig. 22, the height adjustment module includes a height adjustment bracket 72, a limited height wheel 71 is provided on the first side of the height adjustment bracket 72, the second side of the height adjustment bracket 72 is rotatably connected to the cutting panel, at least two fifth mounting holes of different heights are provided between the first side and the second side of the height adjustment bracket 72, and the cutting panel is provided with a sixth mounting hole matching the fifth mounting hole; or at least two sixth mounting holes of different heights are provided on the cutting panel, and the height adjustment bracket is provided with a fifth mounting hole matching the sixth mounting hole;

[0067] When the third fixing member passes through the fifth mounting hole and the sixth mounting hole, the cutting panel is fixed to the height adjustment bracket.

[0068] In some embodiments, a height adjustment pad 73 is provided between the height limiting wheel and the height adjustment bracket.

[0069] In some embodiments, a collision prevention plate 75 is disposed at the front end of the height adjustment bracket.

[0070] like Fig.23 The cutting disc includes a disc body, and a bent disc 61 and a blade 62 are rotatably arranged at the bottom of the disc body from top to bottom in sequence. A driving device 63 (preferably a motor) is arranged on the disc body for driving the bent disc 61 and the blade 62 to rotate; an installation space is arranged inside the cutting panel, and a grass baffle 107 cooperating with the cutting disc is installed in the installation space, and the grass baffle 107 cooperates with the inner wall of the cutting panel 1 to form a grass guide channel, and one side of the cutting end of the blade 62 is rolled up toward the bent disc 61 to form a corner portion, and the acute angle between the bent disc 61 and the plane where the blade 62 is located is 55°-80°.

[0071] In some embodiments, a first through hole is provided on the bending cutter disc, and a second through hole matching the first through hole is provided on the blade. The bending cutter disc and the blade are connected by a bolt 64 (preferably a through bolt), and the bolt 64 shrinks twice from the head to the end direction toward the central axis of the bolt to form a first step and a second step respectively; when the bolt 64 is passed through the second through hole and the first through hole in sequence, the blade and the bending cutter disc are respectively located on the first step and the second step, so that when the resistance applied to the blade is less than or equal to the first force, the blade and the bending cutter disc rotate synchronously, and when the resistance applied to the blade is greater than the first force, the blade can rotate relative to the bending cutter disc.

[0072] In some embodiments, Fig. 20, wear-resistant plates 101 are provided on both sides of the cutting panel, front and rear protection baffles 103 and 106 are provided at the front and rear ends of the cutting panel, respectively, and support wheels 102 are provided at the rear end of the cutting panel, and the rear protection baffles 106 cover the support wheels 102; front mounting seats 105 and rear mounting seats 106 are provided on the upper surface of the cutting panel, respectively, the sixth mounting hole is provided on the front mounting seat, and the second side of the height adjustment bracket is rotatably provided on the rear mounting seat through a rotating sleeve. By providing different protective devices at different positions of the cutting panel, a safety protection function can be achieved, and the overall strength of the cutting platform can be increased.

[0073] For example, Fig.23 The cutting disc specifically includes a driving motor, a bending disc 61, a blade 62, a disc fixing anti-loosening spacer 66, a bolt 64 and an anti-loosening nut sleeve 65. Among them, the driving motor is installed on the cutting panel through a motor mounting seat, which directly provides rotational power for the disc, has good balance, low noise, and is easy to install and maintain. The motor mounting seat plays an installation positioning and protection role for the motor; and the output shaft of the driving motor includes (can be sleeved) a larger mounting boss to ensure that it has a larger joint surface with the bending disc, and high-speed rotation is more stable; the bending disc is at a bending angle and cooperates with the grass collecting plate to complete grass collection and guiding. The blade 62 is a high-strength alloy steel with a coating to increase the cutting performance and cutting life. The bending disc structure makes it possible to achieve excellent grass chopping and grass removal effects while ensuring neat stubble; with the help of the boss and section structure of the bolt 64, the blade 62 can cut a larger When the blade 62 cuts a harder object, the blade 62 can rotate around the bolt 64 between the second step and the head of the bolt 64; at the same time, the anti-loosening nut sleeve 65 and the anti-loosening spacer sleeve have the function of preventing the blade 62 and the bent disc from loosening; and the cutting disc blade 62 can be set to a style with an upward bending angle according to the stubble requirements, with the help of the wind cavity formed therein, so as to achieve better stubble uniformity, grass chopping and grass collecting effects.

[0074] In some embodiments, two semicircular blade disc slots are provided on the output shaft of the driving motor. Correspondingly, the part of the bent blade disc 61 that is combined with the motor output shaft is provided with a protrusion that matches the blade disc slot. The two are engaged and fixed, which can effectively prevent the bent blade disc 61 from loosening during high-speed rotation, thereby increasing safety and reliability.

[0075] In some embodiments, a protective edge is also provided on the driving motor to prevent the high-speed rotating motor shaft from getting entangled with grass during operation.

[0076] See also Fig.21 The connecting bracket includes a left welded bracket and a right welded bracket (that is, the two connecting brackets mentioned above) on the driving body, one end of which is fixed to the cutting panel 1 by a bolt assembly through a connecting mechanism mounting pad, and the other end is connected to the left welded bracket and the right welded bracket on the driving body through a quick latch. The left welded bracket and the right welded bracket are symmetrically arranged, and the left welded bracket and the right welded bracket are combined and fixed to the intermediate bracket 44 on the cutting panel by the intermediate bracket mounting seat 45, and a connecting chain with one end connected to the connecting bracket (including the left welded bracket and the right welded bracket) through a bolt assembly and the other end connected to the spring. The connecting chain 43 has multiple levels and can be adjusted according to the different weights of the cutting platform supported by the connecting bracket and the working state, thereby adjusting the spring force of the spring, changing the load-bearing fulcrum of the cutting platform for the modular intelligent vehicle, and adjusting the overall balance and center of gravity distribution to achieve higher maneuverability and flexibility. The quick locking pins are symmetrically used in four pieces here. For the left side, the first fixing piece 51 is connected to the third mounting hole on the front side of the left welding bracket and the first mounting hole on the front side of the connecting component, and the second fixing piece 52 is connected to one of the fourth mounting holes on the rear side of the right welding bracket and the second mounting hole on the rear side of the connecting component. At the same time, the rear hole of the connecting component is hinged to the trolley body.

[0077] The locking pin front hole group (including the first mounting hole and the third mounting hole) and the locking pin rear hole group (including the second mounting hole and the fourth mounting hole) constitute a height adjustment system. The specific implementation method is that when the first fixing member is inserted into the locking pin front hole group and the second fixing member is inserted into different hole positions of the locking pin rear hole group, the connecting bracket drives the cutting panel 1 and then drives the cutting disc blade to produce different relative heights relative to the trolley chassis connected to the connecting assembly. At the same time, when one of the fixing members (such as the second fixing member) is pulled out of the corresponding hole group (such as the locking pin rear hole group), the cutting panel and all the components it carries can be turned around the fixing member in another hole group (such as the locking pin front hole group). Thereby, maintenance, transfer and transportation are more flexible and convenient. In this process, the spring always has spring tension and is transmitted to the cutting panel along with the left welding bracket and the right welding bracket. The cutting panel expands and contracts with different forces, thereby realizing that the cutting panel 1 floats relative to the trolley in a small range.

[0078] like Fig. 22 and Fig.19The height adjustment module includes a height adjustment bracket 72 (hereinafter referred to as the bracket), an anti-collision plate 75, a height-limiting wheel 71 (also referred to as a height-limiting universal wheel), an adjustment pad 73, and a third fixing member 76 (preferably a quick latch). One end of the bracket is hinged to the height adjustment front mounting of the cutting panel through a rotating sleeve assembly, and can rotate around the rotating sleeve assembly. The other end is fixed to the pin hole group of the rear mounting seat through a quick latch. Since the support wheel installed on it is always grounded, when the quick latch passes through the bracket and is inserted into different holes on the front mounting seat, the cutting panel can have different relative heights relative to the height-limiting universal wheel, thereby allowing the blade to obtain different heights above the ground. At the same time, different heights above the ground can be further obtained by increasing or decreasing the adjustment pad installed between the height-limiting universal wheel and the bracket. In addition, the wear-resistant anti-collision plate installed in front of the bracket can effectively alleviate the impact and wear of the front crop on the bracket and the overall cutting platform during the operation of the cutting platform, thereby improving the service life.

[0081] Walking drive module 31, such as Figure 8 , comprising a driving body 311, a connecting assembly for connecting a functional module is disposed at a first end of the driving body 311, at least one guide rail 312 and a foot support assembly 313 for supporting the driving body are disposed at a second end of the driving body 311, and a driving deceleration system 314 for driving the driving body to walk is also disposed on the driving body;

[0082] Power module 32, such as Fig. 9 , comprising a walking frame 321 and an energy pack 322 arranged on the walking frame, the first end of the power module is provided with at least one pulley 323 capable of sliding on the guide rail; Fig.10 , walking wheels 326 are provided on both sides of the walking frame 321, and the walking wheels cooperate with the driving wheels on the driving body to realize the walking and transfer of the trolley;

[0083] A first quick-release assembly for connecting the travel drive module and the power module, such as Fig.11 , the first quick-release assembly includes a locking member 331 and a locking pin 332, and correspondingly, the second end of the driving body is provided with at least one first through hole and at least one first pin hole, and the first end of the walking frame is provided with at least one second through hole matched with the first through hole, and at least one second pin hole matched with the first pin hole;

[0084] When the pulley is slid along the guide rail to the first position, the first through hole corresponds to the second through hole, the first pin hole corresponds to the second pin hole, the locking pin is passed through the first pin hole and the second pin hole in sequence, and the locking piece is passed through the first through hole and the second through hole in sequence, so that the travel drive module and the power module are quickly connected.

[0085] Specifically, the driving and deceleration systems are two independent motor deceleration driving systems, which can realize differential in-situ steering and can turn on the parking judgment after the whole vehicle is powered off, so as to prevent slipping on sloped roads; the front ends of the walking driving module 31 and the power module 32 are quickly combined into a main vehicle body through the first quick-release assembly. A connecting assembly is arranged in front of the walking driving module, which can quickly mount a mowing platform, a transport cart, a spraying platform, a micro-tillage platform, etc. to realize different operations, and according to the operation requirements, the mounting module can float with the terrain during the working process, quickly flip during maintenance, and lift and fold during transportation. In addition, the power module in the present application is connected to the walking driving module in a quick-release manner, which can easily and quickly replace the power source that matches the power required by the working platform, see Figure 24-26 , gives examples of three different power sources, including pure electric small energy battery, large energy battery and hybrid extended range battery, to adapt to different working platforms. During the transfer process, the walking frame can protect the power source to prevent the power source from being bumped during the transfer process, and the wheels on the driving frame make the transfer process more labor-saving.

[0086] In some embodiments, the first end of the driving body is also provided with a universal interface that cooperates with the functional module. When the modular intelligent car is connected to the functional module through a connecting bracket and a connecting component, the functional module can be connected to the universal interface. After the two are connected, the universal interface is blocked by the functional module, which is more beautiful as a whole. In summary, the modular intelligent car with this interface can quickly match various functional modules. It should be noted that the "universal" here is not the so-called "universal" in the industry or in international standards, but the "universal" that can adapt to different functional modules (including various functional modules independently developed) to transmit power or communicate for them, or communicate while transmitting power.

[0087] In some embodiments, the first quick-release assembly also includes at least one lock, and the lock includes a first buckle arranged at the second end of the driving body, and a second buckle arranged on the walking frame; when the pulley slides to the first position along the guide rail, the first buckle is pressed, and the first buckle is buckled with the second buckle, so that the walking drive module and the power module are quickly connected.

[0088] Exemplarily, the first quick-release assembly includes a quick lock, a quick-release pin (i.e., a locking pin), a lifting ring stop bolt (i.e., a locking member), a guide pulley, and a universal ball. The above components cooperate with each other to quickly disassemble the travel drive module and the power module. Further, when the power module needs to be disassembled, please refer to Fig.10 and Fig.11 First, unlock the lock, then unscrew the eyebolts on the left and right sides from the threaded holes of the walking frame, unscrew the other eye stop bolt from the pin holes on the guide rails on both sides, and pull out the quick-release pin from the pin hole of the drive body to release the connection. The guide pulley on the power module automatically slides out along the guide rail and is separated from the drive body with the help of the universal ball rolling. During the separation and disengagement process, the quick lock bolted to the walking frame is disengaged from the connecting pipe on the frame by its own elastic force, and the entire power pack assembly is transported by the traction handle.

[0089] Further, if Fig.13 and Fig.14 The quick lock includes a handle, a front fixed seat 3341, a pin that hinges the handle to the front fixed seat 3341, a pull rod fixed to the handle, and a rear fixed seat 3342. The front fixed seat 3341 is fixed to the driving body 311, and the rear fixed seat 3342 is fixed to the walking frame 321. When disassembling, the handle is rotated outward 90° around its pin to drive and release the pull rod to escape from the lock hook of the rear fixed seat 3342. When clamping, the operation is reversed. After the operating handle hooks the pull rod to the lock hook of the rear fixed seat 3342, the handle is turned forward to buckle. If necessary, a pin can be used to penetrate the handle and the front fixed seat 3341 to lock the handle.

[0090] In some embodiments, the connecting assembly includes a floating arm and an elastic member, the two ends of the elastic member are respectively connected to the driving body and the functional module, the first end of the floating arm is rotatably connected to the driving body, and the second end of the floating arm is detachably fixed to the functional module.

[0091] In other embodiments, the connecting assembly includes a floating arm, a retractable push rod and a push rod support arm, the first end of the floating arm and the second end of the push rod support arm are respectively rotatably arranged on the driving body, the first end of the push rod support arm is rotatably connected to the second end of the push rod, the first end of the push rod is fixed to the driving body, and a limiting portion for limiting the floating arm is provided on the push rod support arm, and the limiting portion is located below the floating arm; when the push rod contracts, the push rod drives the push rod support arm to rotate around the driving body in a first direction, and the limiting portion abuts against the floating arm, so that the push rod support arm can drive the floating arm to rise; when the push rod is extended, the push rod drives the push rod support arm to rotate around the driving body in a second direction, and the floating arm descends synchronously with the limiting portion; wherein, the first direction and the second direction are opposite. The connection assembly also includes an elastic member, both ends of which are respectively connected to the driving body and the functional module, the first end of the floating arm is rotatably connected to the driving body, and the second end of the floating arm is detachably fixed to the functional module.

[0092] In some embodiments, two floating arms are provided, and the two floating arms are connected by a support rod. Correspondingly, two elastic members, two push rods and two push rod support arms are provided; the two floating arms are respectively connected to the two ends of the support rod through joint bearings; the two push rod support arms are connected by a connecting arm, a support rod is fixed on the connecting arm, and the other end of the support rod is rotatably connected to the driving body.

[0093] For example, Figure 16-Figure 18The floating assembly includes a floating arm 21, a floating spring (elastic member 24), a push rod 22, a push rod support arm 23, a support rod 233, a connecting arm 232, a base 25, and a joint bearing 212. The base 25 is symmetrically arranged with two holes at the front and rear ends thereof being bolted to the driving body, and the middle hole is used to hinge the floating arm 21 and the push rod support arm 23. The floating arms 21 are symmetrically arranged with two holes, connected together by a connecting arm 232, and joint bearings 212 are installed on both sides of the connecting arm 232 to realize the up and down micro-movement of the left and right floating arms. One end of the floating arm 21 is hinged to the middle hole of the base 25, and the other end is connected to the mounting platform (such as a cutting platform) through the front pin hole (i.e., the first mounting hole) and the waist hole (i.e., the second mounting hole). When the mounting platform rises and falls with the terrain, the floating arm 21 is driven to rotate around its hinge point to realize the floating of the mounting platform. One end of the floating spring is hinged to the driving body, and the other end is hung on the connecting chain (also called chain) of the mounting platform, which plays an auxiliary supporting role for the floating arm. The length of the chain hanging point can be adjusted according to the weight of the front mounting platform to achieve the auxiliary effect of different forces. The push rods 22 are also arranged symmetrically, one end is pinned to the driving body, and the other end is pinned to the push rod support arm 23. A part of the push rod support arm 23 spans the left and right floating arms and is arranged below the left and right floating arms. The push rod support arm is provided with two limiting parts 231 (also called grooves) for limiting the left and right floating arms above it. One end of the push rod support arm 23 is pinned on the push rod 22, and the other end is hinged to the middle hole of the base. During the extension and retraction process of the push rod 22, the push rod support arm 23 is driven to rotate. A limit groove 234 is also provided on it, which is used to limit the left and right swing amplitude of the connecting arm 232. The push rod support arm 23 can rotate around the middle hole of the floating arm seat under the push of the push rod 22. When it rotates to a certain angle, it drives the left and right floating arms above it to rise and fall, and then drives the overall lifting and falling of the mounting platform. The push rod support arm is also provided with a mounting seat hole for hinged support rod 233. The other end of the support rod 233 is hinged on the driving body, which assists and protects the push rod. The above structures cooperate with each other to complete the tool-free disassembly, passive floating, active lifting and folding of the mounting platform. It is convenient, fast, safe and efficient, and has high flexibility, applicability and machine utilization.

[0094] In some embodiments, the foot support assembly includes a support body, a first end of the support body is rotatably disposed on the second end of the driving body, and a reset member (preferably a torsion spring) is provided at the first end of the support body; when the power module is installed to the second end of the walking driving module, the support body rotates along a first direction under the push of the power module, and when the pulley slides to the first position, the support body is parallel to the ground; when the power module is separated from the walking driving module, the support body is reset under the action of the reset member, so that the second end of the support body is against the ground.

[0095] For example, Fig.15 The foot support assembly includes a support body 3131, a reset torsion spring (reset member 3132), and a locking pin assembly. The locking pin assembly pins the reset torsion spring and the support body 3131 to the driving body, and the reset torsion spring is placed between the baffle of the driving body and the upper folding surface 3133 of the support body 3131. When the power module and the travel drive module are separated, the support body 3131 rotates downward around the locking pin assembly under the action of the reset torsion spring until it touches the ground, thereby supporting the travel drive module. When the power module is reinstalled, as the power module slides in, its front and rear cross braces will hit the upper folding surface 3133 of the support body 3131, causing it to rotate upward around the locking pin assembly. When the power module is installed in place, the support body 3131 is retracted to a state parallel to the ground. This part supports and retracts when the travel drive module and the power module are quickly disassembled and reassembled, making the device more stable, simple in structure, and convenient to operate.

[0096] In some embodiments, a handle is further provided at the first end of the power module.

[0097] For example, see Fig.12 The handle is connected to the front of the walking frame through a pin assembly and can be stretched and rotated around the waist hole of the locking pin assembly. Specifically, the handle includes a primary handle 3241 and a secondary handle 3242. The secondary handle 3242 can rotate around the rod of the primary handle 3241 to extend the length of the handle for easy operation.

[0098] In some embodiments, Fig. 9 , the power module is also provided with a first control module 325, illustratively, the first control module 325 comprises a main control, an emergency stop and switch assembly box, a rear junction box, a front junction box, a travel drive controller, a camera assembly, a lighting assembly, and a corresponding connection harness. All control and junction box packages are integrated into the corresponding assembly, and the protection level of the whole vehicle reaches IP67, which can meet various complex and harsh working conditions. The junction box is provided with multiple quick-plug waterproof expansion connectors, which are convenient for quick replacement and expansion of functions. The design is simple, maintenance and operation are convenient, the reliability is high, and the expandability is strong. In other embodiments, the main controller, the emergency stop and switch assembly box, and the rear junction box are assembled on the power module, and the front junction box, the travel drive controller box, the camera assembly, and the lighting assembly are assembled on the travel drive module. When disassembling, just unplug the positive power connector, the negative power connector and the communication connector on the front junction box. The travel drive controller can detect the travel load in real time through the control strategy, adaptively control the power output, and save energy and high efficiency. The camera assembly can detect the working condition of the vehicle in real time under remote control or automatic navigation mode, and transmit the images back to assist the operator or the center in making decisions.
