[DETAILED DESCRIPTION]

[0193] The terms used in the present application are merely for the purpose of describing specific embodiments and are not intended to limit the present application. For example, the words "upper", "lower", "front", "back", and the like indicating spatial or positional relationships are based on the orientation or position relationship shown in the drawings, merely for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0194] Unless otherwise specified, the terms "provided", "connected" and "connected" in the present application should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. The "fixed connection" in the present application should also be broadly understood as integrally formed or welded or connected through other fasteners.

[0195] The charging type garden vehicle has the advantages of all-weather zero emission, zero oil consumption, low noise and simple maintenance (no gasoline, no oil, no air filter, no spark plug, no fuel storage, etc.) compared with the traditional fuel type garden vehicle. The power system of the charging type garden vehicle uses an electric motor instead of a fuel engine, and the electric motors of the driving wheels can be controlled respectively to realize straight driving, reverse driving, turning and zero steering of the whole vehicle, reduce the structural complexity of the whole vehicle, and make the control of the whole vehicle more flexible.

[0196] The charging garden vehicle is a complex device system composed of multiple functional components to realize various functions, and the most critical mechanism is the combination of various electric motors and other functional components used. In the charging garden vehicle, each functional component needs to be provided with safe, accurate and stable control to ensure efficient and reliable operation of the whole vehicle.

[0197] Specifically, in some related technical solutions, a corresponding controller is independently provided for each functional component, and the multiple controllers are integrally connected. This way requires setting enough wire harnesses and terminals, especially at the position directly controlled by the user. The complex wire harness not only leads to greater difficulty in wiring during production, but also increases the difficulty of later maintenance. In addition, during long-term use, more wire harnesses also significantly increase the risk of line aging.

[0198] Therefore, the multifunctional garden vehicle disclosed in the embodiment integrates the signals at the user control position, greatly reduces the required wire harnesses and terminals, reduces production costs, and improves product safety and stability.

[0199] Based on the above purpose, the embodiment of the present specification discloses a multifunctional garden vehicle, comprising a vehicle frame 1, a functional mechanism, and a power supply system 6; the vehicle frame 1 extends in the forward direction of the vehicle, and the power supply system 6 and the functional mechanism are connected to the vehicle frame 1; the power supply system 6 is at least used to supply power to one of the functional mechanisms. In addition, the power supply system 6 can also supply power to other electronic components in the garden vehicle, such as a human-computer interaction system, etc.

[0200] The above-mentioned power supply system 6 is arranged on the vehicle frame 1, and part of it is detachably connected to the vehicle frame 1. The power supply system 6 comprises a plurality of battery units. The plurality of battery units can select at least one of a first specification battery pack and a second specification battery pack. The specification difference between the first specification battery pack and the second specification battery pack includes but is not limited to the difference in battery pack capacity, voltage, battery internal resistance, weight, size, energy density, battery cell type, charge information, battery health state information, etc.

[0201] In some optional embodiments, the difference between the first specification battery pack and the second specification battery pack is that the battery pack capacity is different. The capacity of the first specification battery pack is greater than that of the second specification battery pack. The second specification battery pack is configured to provide power for handheld garden tools. For example, the second specification battery pack can provide power for garden tools such as grass trimmers, pruning machines, blowers, chain saws, etc. In addition, the second specification battery pack can also provide power for torque output tools such as electric drills and electric hammers; for sawing tools such as electric circular saws, curved saws, and reciprocating saws; or for grinding tools such as angle grinders and sanders.

[0202] In some optional embodiments, the first specification battery pack and the second specification battery pack differ in that they use different types of battery cells. For example, the first specification battery pack and the second specification battery pack can use lithium iron phosphate battery cells and ternary lithium battery cells, respectively. The battery cells in the power supply system 6 can also use nickel-chromium battery cells, lead-acid battery cells, graphene battery cells, etc.

[0203] The battery cells in the power supply system 6 use at least one of the first specification battery pack and the second specification battery pack. This allows the multifunctional vehicle to be compatible with battery packs of different specifications, meeting the demand for high-power work while also being able to adapt to handheld electric garden tools, making the work of garden workers more flexible.

[0204] In one optional embodiment, the power supply system 6 further includes a battery compartment and a battery management system. The battery compartment is used to accommodate the battery pack, and the battery management system is used to manage the power supply of the vehicle components by the battery.

[0205] In one optional embodiment, the battery compartment and / or the battery management system are configured on the vehicle frame, and the battery pack is detachably configured in the battery compartment, so as to realize the detachable replacement of the battery pack, and the detached battery pack can be used in other electric garden tools.

[0206] In one optional embodiment, the battery compartment is detachably configured on the vehicle frame, and the battery pack is accommodated in the battery compartment, i.e., the battery compartment can be separated from or combined with the vehicle frame as a whole.

[0207] In one specific optional embodiment, a power supply interface is configured on the vehicle frame, the battery compartment is hung on the vehicle and electrically connected with the power supply interface, and the battery compartment as a whole can be detached, so that the user can replace all the battery packs at the fastest speed, i.e., when it is necessary to supplement the power of the vehicle by replacing the battery pack, the overall replacement of the battery compartment has higher efficiency.

[0208] The functional mechanisms in the embodiment include garden work components and walking assemblies for changing the functional state of the multifunctional garden vehicle. The garden work components are used for garden maintenance work, and the walking assemblies are drivingly connected to the driving wheels on the left and right sides of the vehicle frame 1 to drive the multifunctional garden vehicle to travel.

[0209] The multifunctional garden vehicle further includes a positive steering assembly that is operatively coupled to the walking assembly of the multifunctional garden vehicle to cause the driving wheels on the left and right sides to have a speed difference and make the garden vehicle rotate. That is, the positive steering assembly can actively cause the driving wheels on the left and right sides to have a speed difference when controlled by a person, rather than causing the driving wheels to have a speed difference when the vehicle is driven by an external force.

[0210] The garden vehicle further comprises a controller system capable of controlling the functional mechanism and causing the functional state change.

[0211] The active steering assembly in the embodiment further comprises a control handle 4 held and operated by the user, the control handle 4 is provided with a control panel and at least two operation controls coupled to the control panel, a single operation control can be used to control one of the functional mechanisms and cause the functional state change, the signals generated by the at least two operation controls are transmitted to the controller system after being integrated by the control panel, so that the controller system controls the functional mechanism to cause the functional state change.

[0212] The operation control generates a control instruction when operated by the user, the instruction is information for causing one of the functional mechanisms to cause the functional state change; and different operation controls should be able to issue different instructions. In the embodiment, the control panel can respond to the instructions of the at least two operation controls, and send a signal to the controller system after integrating the instructions of the two operation controls.

[0213] It is further explained that the at least two operation controls issue mutually independent signals, and the control panel combines the mutually independent signals into a composite signal that can be transmitted on the same channel and sends it to the control panel. Common methods include frequency division multiplexing, code division multiplexing, time division multiplexing, etc.

[0214] Since the integrated signal can be transmitted on the same channel, the wire harness for transmitting the signal can be greatly reduced, solving the technical problem caused by the large number of wire harnesses and terminal posts. It is further explained that the more operation controls of the control handle 4 or the more types of signals that the operation controls can send, the more wire harnesses that can be reduced, and the more obvious the technical effect.

[0215] Please refer to FIG. 1, the garden operation component in the embodiment is a mowing deck 8 connected to the vehicle frame 1, the mowing deck 8 comprises a rotary cutter for mowing grass. In other embodiments, the garden operation component can also be selected to have a component with the functions of snow sweeping, snow blowing, snow shoveling, flushing, and shovel, or a component for grabbing and carrying goods to assist construction during garden operation. Those skilled in the art should be able to adaptively replace the operation assembly in the embodiment with various functional components without creative labor, and all of the above should be included in the protection scope of the embodiment.

[0216] As mentioned above, when the garden working component is the mowing deck 8, the multifunctional garden vehicle is a mower; further, when the garden working component is a snow sweeping component, the multifunctional garden vehicle is a snow sweeper; that is, the garden working component as the main functional component of the multifunctional garden vehicle can be changed according to the selection of the user; meanwhile, in some embodiments, the garden working component can also be a component replaced by the user according to the actual needs, for example, the mowing deck 8 used for mowing is disassembled and replaced by a sweeping disc used for sweeping, so as to change the mower into a sweeper; in summary: the garden working component is replaced by any functional component according to the user's needs, which should not be understood as breaking the protection scope of the embodiment.

[0217] Again, referring to Fig. 1, the active steering assembly in the embodiment is configured as a steering lever pivotally connected to the frame 1, when steering, the user controls the vehicle driving and steering by rotating the steering lever. In other embodiments, the active steering assembly can also be configured as a steering wheel component, the control handle 4 is a partial structure of the steering wheel convenient for holding, and the vehicle is steered according to the rotation amount of the steering wheel component controlled by the user.

[0218] Referring to Figs. 4, 5 and 7, the control board of the embodiment is configured with a microprocessor, which sends a signal to change the current of the functional mechanism when the control handle is controlled by the user, so as to change the functional state of the functional mechanism.

[0219] Specifically, referring to Fig. 4, which is an exploded schematic view of the first control handle 414, the first control handle 414 includes a first control assembly 4121 and a first control board 4122; referring to Fig. 5, which is an exploded schematic view of the second control handle 42, the second control handle 42 includes a second control assembly 4221 and a second control board 4222; the first control board 4122 and the second control board 4222 are both provided with a microprocessor; referring to Fig. 7, which is a structural schematic view of the second control board 4222, the second control board 4222 includes a second control board body 4222 and a second microprocessor 42222 arranged on the second control board body 4222.

[0220] The cutting platform 8 in the embodiment includes a mowing motor for driving the cutting knife to rotate. In different working conditions and mowing requirements, the required rotating speed of the cutting knife is different. Therefore, the mowing motor is configured with multiple target rotating speeds. The user controls the control handle to make the control panel send a control signal to configure the rotating speed of the mowing motor as one of the target rotating speeds. For example, when the grass to be cut is relatively dense or the user wants to complete the effective cutting in a shorter time, the cutting platform 8 can be adjusted by increasing the rotating speed of the cutting knife. Specifically, the target rotating speed of the mowing motor is increased. At this time, the control unit of the mowing motor adjusts the duty cycle of the motor, so that the rotating speed of the mowing motor increases and approaches the target rotating speed, until the actual rotating speed of the mowing motor is equal to the target rotating speed. Conversely, if the grass to be cut is relatively sparse, or the user is not in a hurry to complete the mowing quickly but is more energy-saving, the target rotating speed of the mowing motor should be reduced. At this time, the control unit of the mowing motor adjusts the duty cycle of the motor, so that the rotating speed of the mowing motor decreases and approaches the target rotating speed, until the actual rotating speed of the mowing motor is equal to the target rotating speed.

[0221] The multiple target rotating speeds of the mowing motor are sequentially increased or decreased. The control handle is configured to configure the rotating speed of the mowing motor as the corresponding target rotating speed according to the number of user manipulations. In the embodiment, the mowing motor includes the following three target rotating speeds: 2800 RPM (Revolutions Per Minute), 3000 RPM, and 3200 RPM. The cutting knife has a diameter of 21 inches. The linear speed (i.e., the tip speed) of the end of the cutting knife driven to rotate at the above three target rotating speeds is different, which is suitable for mowing requirements in different situations. The control handle directly controlled by the user can be configured to have one or two trigger states.

[0222] In some optional embodiments, the control handle only includes one trigger state. The mowing motor should be configured in a plurality of target rotating speeds in a cycle according to the number of times the control handle is triggered to the trigger state. For example, the embodiment is configured with the above three target rotating speeds, which are defined as high, medium, and low. Assuming that the initial state of the mowing motor is the low target rotating speed, when the control handle is manipulated to the trigger state once or twice, the rotating speed of the mowing motor is configured as the medium and high target rotating speeds in turn. The third time the trigger state is reached will enter the above target rotating speeds in a cycle, such as entering the low target rotating speed again when the third time the trigger state is reached, entering the medium target rotating speed when the fourth time the trigger state is reached, and so on. Further, the above cycle configuration has other implementation manners, such as a cycle manner of low, high, medium, and low.

[0223] In addition, in other embodiments, the mowing motor can also include four or more target rotating speeds. Those skilled in the art should be able to configure them in the above order without creative labor, which should be included in the protection scope of the embodiment.

[0224] In some alternative embodiments, the control member comprises two trigger states, such as a first trigger state and a second trigger state, and the target speed of the mower motor should be changed differently when the control member is in the two trigger states. For example, the mower motor has three target speeds, which are defined as high, medium and low. Assuming that the initial state of the mower motor is configured as the low target speed, when the control member is in the first trigger state for the first time and the second time, the target speed of the mower motor is configured as the medium target speed and the high target speed, respectively. When the initial state of the mower motor is configured as the high target speed, when the control member is in the second trigger state for the first time and the second time, the target speed of the mower motor is configured as the medium target speed and the low target speed, respectively.

[0225] In summary, the target speed of the mower motor can be switched in multiple sequences, and the switching sequence of the target speed of the mower motor is different when the control member is in different trigger states. Further, the control member can comprise more trigger states, and the target speed of the mower motor is switched in different sequences in different trigger states.

[0226] It is particularly noted that in some embodiments, in order to reduce the situation that the operation of the user causes the speed of the cutter to change drastically, the control mode in which the target speed is cyclically changed as “high, medium, low, high” or “low, medium, high, low” is generally not set, because the control mode of the above-mentioned cyclically changed target speed will cause the speed of the cutter to change too much in a short time. For example, the speed of the cutter is increased from the lowest speed to the highest speed or decreased from the highest speed to the lowest speed in a short time. Especially when the speed of the cutter is directly increased from the lowest target speed to the highest target speed, there is a high probability that the noise and vibration will be obviously increased, and the user will have an uncomfortable experience.

[0227] Therefore, the operation member is generally provided with two trigger states, and the mower motor is configured with multiple target speeds. When the operation member is in one of the trigger states, the mower motor is changed by one speed gear from the current speed to the highest speed, until the mower motor is configured as the highest speed gear. Conversely, when the operation member is in the other trigger state, the mower motor is changed by one speed gear from the current speed to the lowest speed, until the mower motor is configured as the lowest speed gear. In this embodiment, the user can configure the mower motor to any target speed by operating the control member, and there is no large difference between the target speeds before and after the target speed is switched each time, that is, there is no problem of reducing the user experience caused by the sudden change of the speed.

[0228] In another optional embodiment, the control handle is configured to include more than two trigger states, such as three trigger states, and so on, and each trigger state should be associated with a target rotating speed, i.e. when the user places the control handle in one of the trigger states, the mower motor changes to a specific target rotating speed; when the user places the control handle in another trigger state, the mower motor changes to another specific target rotating speed. In this embodiment, three trigger states are provided, corresponding to high, medium and low target rotating speeds respectively, and when the user places the trigger member in a certain trigger state, the mower motor is adjusted to the corresponding target rotating speed.

[0229] In particular, in another optional embodiment, the mower motor is also configured with an adaptive target rotating speed, which is not a constant rotating speed value, and at the adaptive target rotating speed, the garden vehicle enters the mower blade rotating speed adaptive state, and the real-time rotating speed of the mower blade changes with the density of the grass at the working position: when the grass is dense, the rotating speed of the mower blade increases; when the grass is sparse, the rotating speed of the mower blade decreases; so that the mower blade can complete the mowing more economically, i.e. the relationship between the power of the mower blade and the density of the grass to be mowed is optimized, and the relationship between the power consumption of the mower blade and the mowing efficiency is balanced.

[0230] In another optional embodiment, the user controls the control handle to switch the mower motor between the adaptive target rotating speed and other target rotating speeds with constant rotating speeds.

[0231] In this another optional embodiment, the driving assembly includes a driving motor for driving the driving wheels to rotate, and the driving motor is configured with multiple speed ranges, and the user controls the control handle to make the control board send a control signal to configure the rotating speed range of the driving motor to one of the speed ranges, and the multiple speed ranges of the driving motor have different maximum speeds; for example, the rotating speed range of the driving motor is configured to three speed ranges: fast, medium and slow, and the maximum rotating speeds of the three speed ranges decrease in turn, and the minimum rotating speeds of the three speed ranges are all zero, i.e. when the driving motor is in various speed ranges, the mower can start from a stationary state to the maximum value of the current speed range.

[0232] In a specific implementation state, the mower is at 50% of the maximum driving speed of the current speed range, and when the user adjusts the speed range of the mower, the actual driving speed of the mower should also change, specifically: when the mower is adjusted from the slow speed range to the medium speed range, it should be adjusted from 50% of the maximum driving speed of the slow speed range to 50% of the maximum driving speed of the medium speed range. In summary, the driving motor of this embodiment is configured with multiple speed ranges to facilitate the user to set the mower to the required speed more conveniently and quickly.

[0233] In particular, in one optional embodiment, referring to FIG. 1, FIG. 2 and FIG. 3, the active steering assembly is configured as a steering lever, the steering lever is pivoted on the frame 1 and the deflection angle of the steering lever is positively correlated with the rotation speed of the traveling motor, the steering lever can be deflected forward or backward on the frame 1 about a first axis, and the steering lever has a first forward position deflected to the most forward position, a first backward position deflected to the most backward position, and an intermediate position; the first axis is parallel to the left-right direction of the vehicle.

[0234] When the steering lever is in the intermediate position, the traveling motor does not drive the driving wheel to rotate, at this time the vehicle is in a stationary state. When the steering lever is in the first forward position, the real-time rotation speed of the traveling motor is equal to the maximum rotation speed of the current speed range. When the steering lever is between the intermediate position and the first forward position, the real-time rotation speed of the traveling motor is less than the maximum rotation speed of the current speed range, and when the steering lever continues to deflect towards the first forward position, the real-time rotation speed of the traveling motor increases.

[0235] Further, in one optional embodiment, the maximum speeds of the multiple speed ranges of the traveling motor are sequentially increased, and the control means is configured to sequentially configure the rotation speed range of the traveling motor as the corresponding speed range according to the number of times of user control. That is, the multiple speed ranges of the traveling motor are sequentially set, and when the control means is controlled by the user, the speed range of the traveling motor is sequentially transformed between each rotation speed range.

[0236] As mentioned above, the control means for controlling the speed range of the traveling motor can have several trigger states.

[0237] In one optional embodiment, the control means for controlling the speed range of the traveling motor has one trigger state, at this time the traveling motor should be configured in the multiple speed ranges according to the number of times the control means is triggered to the trigger state, for example: this embodiment configures the above-mentioned three speed ranges, which are defined as fast, medium and slow respectively;

[0238] In one optional embodiment, the order of the above-mentioned cyclically configured speed ranges is slow, medium, fast, slow; for example: assuming that the initial state of the traveling motor is the slow target rotation speed, when the control means is controlled to the trigger state once or twice, the rotation speed of the traveling motor is configured to the medium target rotation speed and the fast target rotation speed respectively; the third time reaching the trigger state will cyclically enter the above-mentioned speed range, that is, the third time reaching the trigger state will reconfigure the traveling motor to the slow target rotation speed, the fourth time reaching the trigger state will reconfigure the traveling motor to the medium target rotation speed, and so on; further, the above-mentioned cyclically configured speed ranges have other implementation manners: such as the cyclically configured speed ranges in the order of fast, medium, slow, fast, etc.

[0239] In another alternative embodiment, the control for operating the speed range of the traveling motor has two trigger states, when the control is in the first trigger state, the traveling motor changes among the fast, medium and slow speed ranges in a sequence; when the control is in the second trigger state, the traveling motor changes among the fast, medium and slow speed ranges in another sequence.

[0240] More specifically, when the control is in the first trigger state, the traveling motor changes among the fast, medium and slow speed ranges in the sequence of fast, medium and slow; for example, when the traveling motor is currently in the fast speed range and the control is in the first trigger state, the traveling motor changes to the medium speed range, and when the control is in the first trigger state again, the traveling motor changes to the slow speed range.

[0241] When the control is in the second trigger state, the traveling motor changes among the fast, medium and slow speed ranges in the sequence of slow, medium and fast; for example, when the traveling motor is currently in the slow speed range and the control is in the second trigger state, the traveling motor changes to the medium speed range, and when the control is in the second trigger state again, the traveling motor changes to the fast speed range.

[0242] It is additionally noted that, referring to the aforementioned configuration of the mowing motor target speed not to cycle, the traveling motor can also have a similar configuration, i.e., the speed range of the traveling motor is not set to cycle, which is also to avoid the drastic change of the traveling speed and reduce the driving experience; for example, when the control is in the first trigger state, the traveling motor changes among the fast, medium and slow speed ranges in the sequence of fast, medium and slow, and when the control is in the first trigger state again when the traveling motor is in the fast speed range, the speed range of the traveling motor does not change; conversely, when the control is in the second trigger state when the traveling motor is in the slow speed range, the speed range of the traveling motor also does not change.

[0243] In another alternative embodiment, the control can also be configured to include more than two trigger states, such as three trigger states, and the like, at which time each trigger state should be associated with a speed range, i.e., when the user places the control in one of the trigger states, the traveling motor changes to a specific speed range; when the user places the control in another trigger state, the traveling motor changes to another specific speed range. For example, in this embodiment, three trigger states are provided, corresponding to the fast, medium and slow target speeds, and when the user places the trigger in a trigger state, the traveling motor is adjusted to the corresponding target speed.

[0244] In other embodiments, the traveling motor can also be configured to include four or more speed ranges, and those skilled in the art should be able to configure the above sequence without creative labor, which should be included in the protection scope of the present embodiment.

[0245] Referring to FIG. 1, FIG. 2, FIG. 3, the steering rod comprises a first steering rod 2 and a second steering rod 3, the driving motor comprises a first driving motor and a second driving motor, and the driving wheel comprises a first driving wheel and a second driving wheel; the user adjusts the deflection angle of the first steering rod 2 to adjust the rotating speed of the first driving motor driving the first driving wheel to rotate, and adjusts the deflection angle of the second steering rod 3 to adjust the rotating speed of the second driving motor driving the second driving wheel to rotate. When there is a difference between the deflection angles of the two steering rods, the driving motor drives the driving wheel at different rotating speeds, so that the two driving wheels have a rotating speed difference, and the garden vehicle turns.

[0246] In some embodiments of the present application, the multifunctional garden vehicle further comprises an alignment detection module for judging whether the deflection angles of the first steering rod 2 and the second steering rod 3 are consistent, and the alignment detection module is coupled to the controller system; when the alignment detection module judges that the deflection angles of the two steering rods are consistent, the controller system controls the two driving wheels to rotate at the same rotating speed.

[0247] The alignment detection module can realize the corresponding effect by using indirect detection and direct detection:

[0248] In one of the optional embodiments, the indirect detection is to separately detect the deflection angles of the first steering rod 2 and the second steering rod 3 relative to the vehicle frame 1, and compare the two deflection angles to judge whether the two steering rods are aligned; in this embodiment, a detection component for detecting the deflection angle of any steering rod relative to the vehicle frame 1 should be configured.

[0249] In one of the optional embodiments, a deflection identifier is configured at the connection between the steering rod and the vehicle frame 1; specifically, the deflection identifier is an angle sensor for measuring the deflection angle of the steering rod relative to the vehicle; after the deflection angles of the two steering rods are measured, they can be compared; if the deflection angles of the two steering rods are consistent, it is considered that the user has the intention to make the vehicle travel straight, and at this time the controller system controls the two driving wheels to rotate at the same rotating speed, that is, the vehicle enters the straight travel state.

[0250] Due to the existence of assembly error and measurement error of the angle sensor, the angle sensor cannot extremely accurately detect the deflection angles of the two steering rods relative to the vehicle frame 1; at the same time, the manual operation of the user is also difficult to make the two steering rods keep very accurate consistent deflection angles, so a deviation threshold for judging whether the user has the intention to travel straight is set.

[0251] In an alternative embodiment, the alignment detection module measures the deflection angles of the two steering levers by means of an angle sensor, calculates the difference between the deflection angles of the two steering levers and compares the difference with the angle deviation threshold value, and if the difference is less than the angle deviation threshold value, it is determined that the user has the intention to make the vehicle travel straight, i.e., the angle deviation of the two steering levers is consistent and the two driving wheels are controlled to rotate at the same speed.

[0252] Further, in another embodiment, the control key is configured to control the control panel to send a control signal and change the value of the angle deviation threshold value, i.e., in this embodiment, the angle deviation threshold value is not a fixed value but can be selected from a plurality of values under the control of the user; for example, three angle deviation threshold values are configured in the alignment detection module: a large angle deviation threshold value, a medium angle deviation threshold value, and a small angle deviation threshold value. The control key is used to select or switch between the three angle deviation threshold values, and the switching method and order can be configured by referring to the aforementioned method and order for switching the driving speed range or the target rotating speed range of the cutter, which will not be described here.

[0253] When the control key is controlled to select the large angle deviation threshold value, i.e., when there is a slightly larger deflection angle deviation between the two steering levers, it can still be determined that the user has the intention to travel straight; conversely, when the control key is controlled to select the small angle deviation threshold value, i.e., when there is a smaller deflection angle deviation between the two steering levers, it can be determined that the user has the intention to travel straight; correspondingly, the medium angle deviation threshold value is a compromise technical solution.

[0254] Further, the control key is configured to change the angle deviation threshold value in a group of predetermined values under the control of the user, and in this embodiment, the control key is configured to switch between the plurality of angle deviation threshold values in a cycle.

[0255] In another alternative embodiment, the alignment detection module uses a direct detection method to achieve the corresponding effect, i.e., directly detecting whether the relative angles of the two steering levers are consistent, specifically: the alignment detection module includes a signal transmitting part and a signal receiving part configured on the two control handles 4, and the signal receiving part receives the signal transmitted by the signal transmitting part when the two steering levers are aligned and controls the two driving wheels to rotate at the same speed. That is, the signal transmitting part is configured on one of the control handles 4, and the signal receiving part is configured on the other control handle 4, and when the deflection angles of the two steering levers are consistent, the signal receiving part can receive the signal transmitted by the signal transmitting part.

[0256] Referring to FIG. 10, a position relationship diagram of the signal transmitter and the signal receiver in an embodiment is shown. A1 and C1 positions represent that the signal transmitter and the signal receiver do not correspond, i.e., the deflection angles of the two steering levers are inconsistent. B1 position represents that the signal transmitter and the signal receiver correspond, i.e., the deflection angles of the two steering levers are consistent.

[0257] In some optional embodiments, the alignment detection module described above can be selected from an infrared sensor module, a laser sensor module, an image recognition module, a Hall sensor module, or an ultrasonic sensor module.

[0258] In an optional embodiment, the signal transmitter and the signal receiver in the infrared sensor module are respectively selected from an infrared signal transmitter and an infrared signal receiver. When the deflection angles of the two steering levers are consistent, the light emitted by the infrared signal transmitter can be received by the infrared signal receiver. At this time, it is determined that the user has the intention to make the vehicle travel straight, and the controller system sends a signal to the two drive wheels to run at the same speed.

[0259] In an optional embodiment, the signal transmitter and the signal receiver in the laser sensor module are respectively selected from a laser signal transmitter and a laser signal receiver. When the deflection angles of the two steering levers are consistent, the light emitted by the laser signal transmitter can be received by the laser signal receiver. At this time, it is determined that the user has the intention to make the vehicle travel straight, and the controller system sends a signal to the two drive wheels to run at the same speed.

[0260] In an optional embodiment, the signal transmitter and the signal receiver in the image recognition module are respectively selected from a specific image and a photographing element. The specific image in this embodiment can emit light or reflect external light to the photographing element. When the deflection angles of the two steering levers are consistent, the light emitted (or reflected) by the specific image can be received by the photographing element. At this time, it is determined that the user has the intention to make the vehicle travel straight, and the controller system sends a signal to the two drive wheels to run at the same speed.

[0261] In an optional embodiment, the signal transmitter and the signal receiver in the Hall sensor module are respectively selected from a magnetic element and a Hall sensing element. When the deflection angles of the two steering levers are consistent, the magnetic induction lines of the magnetic element can be received by the Hall sensing element. At this time, it is determined that the user has the intention to make the vehicle travel straight, and the controller system sends a signal to the two drive wheels to run at the same speed.

[0262] In an optional embodiment, the signal transmitter and the signal receiver in the ultrasonic sensor module are respectively an ultrasonic transmitter and an ultrasonic receiver. When the deflection angles of the two steering levers are consistent, the light emitted by the ultrasonic transmitter can be received by the infrared signal receiver, at which time it is determined that the user has the intention to make the vehicle travel straight, and the controller system sends a signal to the two drive wheels to run at the same speed.

[0263] The above-mentioned various signal transmitters and signal receivers can effectively determine whether the deflection angles of the two steering levers are consistent, thereby sending a signal to the two drive wheels to run at the same speed.

[0264] In the above-mentioned embodiments, the signal transmitter and the signal receiver are respectively located in the two control handles 4, specifically, the infrared signal transmitter is located in one of the control handles 4, and the infrared signal receiver is located in the other control handle 4. The signal emitted by the signal transmitter can be directly received by the signal receiver when the deflection angles of the two steering levers are consistent.

[0265] In another optional embodiment, the alignment detection module further comprises a reflector for reflecting the signal emitted by the signal transmitter. In this embodiment, the signal transmitter and the signal reflector can be arranged in the same control handle 4, and the reflector is arranged in the other control handle 4. When the deflection angles of the two steering levers are consistent, the reflector reflects the signal emitted by the signal transmitter and received by the signal receiver, thereby effectively determining whether the deflection angles of the two steering levers are consistent, and sending a signal to the two drive wheels to run at the same speed.

[0266] In one optional embodiment, as shown in FIG. 11, the semicircles of the signal transmitter and the signal receiver represent the local areas for transmitting and receiving signals. The positions A2 and C2 represent that the deflection angles of the two steering levers are inconsistent, and the position B2 represents that the deflection angles of the two steering levers are consistent. When the reflector is at the position B2 relative to the signal transmitter, the reflector can effectively reflect the signal emitted by the signal transmitter to the signal receiver, so that the signal receiver can receive the signal and determine that the deflection angles of the two steering levers are consistent, thereby sending a signal to the two drive wheels to run at the same speed.

[0267] When the alignment detection module uses an infrared sensor module, the reflector is an infrared reflector.

[0268] When the alignment detection module uses a laser sensor module, the reflector is a laser reflector.

[0269] When the alignment detection module uses an image recognition module, the reflector is a mirror.

[0270] In one of the optional embodiments, the alignment detector comprises the signal emitter and the signal receiver as described above. When the deflection angles of the two steering rods are similar but not equal, the signal receiver can receive the signal emitted by the signal emitter; when the deflection angles of the two steering rods are completely equal, the signal receiver can receive a stronger signal emitted by the signal emitter. The alignment detection module in this embodiment is provided with a preset signal strength threshold for judging whether the user has the straight driving intention.

[0271] In one of the optional embodiments, referring to FIG. 12, the signal emitter and the signal receiver in this embodiment are respectively located on the two steering rods. D1, E1 and F1 in the figure respectively represent three relative position relationships of the two steering rods. D1 and F1 represent that the deflection angles of the two steering rods are similar but not equal, and E1 represents that the deflection angles of the two steering rods are equal. The horizontal arrowed lines in the figure represent the signals emitted by the signal emitter. The solid lines represent the signals that can be received by the signal receiver, and the dashed lines represent the signals that cannot be received by the signal receiver.

[0272] The number of the solid lines represents the strength of the signals that can be received by the signal receiver. Obviously, the strength of the signals that can be received by the signal receiver is positively correlated with the alignment degree of the two steering rods, that is, the more similar the deflection angles of the two steering rods are, the stronger the signals that can be received by the signal receiver are.

[0273] In another optional embodiment, referring to FIG. 13, the signal emitter and the signal receiver in this embodiment are respectively located on the same steering rod, and the other steering rod is provided with a reflector. G, H and I in the figure respectively represent three relative position relationships of the two steering rods. G and I represent that the deflection angles of the two steering rods are similar but not equal, and H represents that the deflection angles of the two steering rods are equal. The arrowed solid lines in the figure represent the signals that can be received by the signal receiver, and the arrowed dashed lines represent the signals that cannot be received by the signal receiver.

[0274] When the reflector is in the H position relative to the signal emitter, the reflector can reflect all the signals emitted by the signal emitter to the signal receiver. When the reflector is in the G or I position relative to the signal emitter, the reflector can only reflect part of the signals emitted by the signal emitter to the signal receiver.

[0275] That is, when the deflection angles of the two steering rods are completely consistent, the reflector can reflect the most signals to the signal receiver, so that the signal receiver receives the strongest signal. The more similar the deflection angles of the two steering rods are, the more signals the reflector can reflect to the signal receiver, and the stronger the signals that can be received by the signal receiver are.

[0276] As mentioned above, the preset signal strength threshold is configured in the embodiment, when the received signal strength is greater than the threshold, that is, the deflection angles of the two steering levers are similar, and it is determined that the user has the intention to make the garden vehicle travel straight, and the two drive wheels are controlled to run at the same speed; otherwise, it is determined that the user does not have the intention to travel straight, and the two drive wheels travel according to the corresponding speed of the actual deflection angle of the corresponding steering lever.

[0277] Further, the alignment detection module selects the embodiments of infrared sensors, laser sensors, and image recognition sensors, which are all applicable to the configuration of the preset signal strength threshold. Because infrared light, laser, and image can be configured to have a width of light signal, the technical effect of being able to accept different signal values can be achieved.

[0278] Referring to FIG. 14, the technical solution of the alignment detector selects Hall sensing elements and magnetic elements. In the embodiment, the Hall sensing elements and the magnetic elements are arranged at the ends of the first steering lever 2 and the second steering lever 3, that is, the Hall sensing elements and the magnetic elements are respectively installed at the control handles 4 of the two steering levers. When the first steering lever 2 and the second steering lever 3 are aligned, the Hall sensing elements and the magnetic elements are opposite.

[0279] Again referring to FIG. 14, it is a schematic diagram of different spatial position relationships of the Hall sensing elements and the magnetic elements. The semicircles of the magnetic elements and the Hall sensing elements in the figure respectively represent the local areas of the transmitted and received magnetic induction lines. The curved lines with arrows in the figure represent the magnetic induction lines, and the density of the magnetic induction lines represents the magnetic field strength at the corresponding position. It is additionally explained that: the above-mentioned magnetic induction lines are only imaginary curves for describing the magnetic field strength, and do not indicate that they are real curves existing in the magnetic field, and should not be understood as a reason for limiting the protection scope of the embodiment.

[0280] As shown in FIG. 14: when the Hall sensing elements and the magnetic elements are in the spatial position relationship K, they are in the opposite relationship, at this time, the deflection angles of the first steering lever 2 and the second steering lever 3 are consistent, and the magnetic field strength detected by the Hall sensing elements is the largest. When the Hall sensing elements and the magnetic elements are in other spatial position relationships, such as the spatial position relationship J and the spatial position relationship L, the magnetic field strength detected by the Hall sensing elements decreases; that is, the more similar the deflection angles of the two steering levers are, the greater the magnetic field strength is; on the contrary, the greater the difference between the deflection angles of the two steering levers is, the smaller the magnetic field strength is, or even the magnetic field strength cannot be detected.

[0281] As mentioned above, the alignment detection module is configured with Hall effect elements and magnetic elements. The alignment detection module is configured with a preset field strength threshold. When the magnetic field strength detected by the Hall effect elements is greater than the preset field strength threshold, it is determined that the deflection angles of the two steering levers are consistent, i.e., the user has the intention to make the vehicle travel straight, and the two drive wheels are controlled to rotate at the same speed. Conversely, when the magnetic field strength detected by the Hall effect elements is less than the preset field strength threshold, it is determined that the deflection angles of the two steering levers are inconsistent, i.e., the user has the intention to make the vehicle turn, and the two drive wheels are controlled to rotate at speeds corresponding to the actual deflection angles of the corresponding steering levers to achieve the action of turning the vehicle.

[0282] Further, in another embodiment, the control is configured to change the value of the preset field strength threshold by the user. In this embodiment, the preset field strength threshold is not a fixed value, but can be selected from a plurality of values by the user. For example, three preset field strength thresholds are configured in the alignment detection module: a large preset field strength threshold, a medium preset field strength threshold, and a small preset field strength threshold. The control is used to select or switch between the three preset field strength thresholds. The switching method and order can be configured according to the driving speed range or the target speed of the cutting blade, which will not be described here.

[0283] When the control selects the large preset field strength threshold, it is still determined that the user has the intention to travel straight even if there is a slight deflection angle deviation between the two steering levers. Conversely, when the control selects the small preset field strength threshold, it is determined that the user has the intention to travel straight only if there is a small deflection angle deviation between the two steering levers. Correspondingly, the medium preset field strength threshold is a compromise technical solution.

[0284] In another optional embodiment, the function of one or more controls can be defined by the user, such as the one or more controls used to adjust the driving motor speed range. Another control on the control handle 4 or a button on the vehicle can be used to configure the one or more controls to adjust the target speed of the cutting motor. On the other hand, the control can be configured to adjust the angle deviation threshold, the signal strength threshold, or the preset field strength threshold.

[0285] In another optional embodiment, at least two functional mechanisms also include lighting fixtures located at the front or rear of the multi-functional garden vehicle. The user controls the control unit to send a control signal to the control panel, changing the operating current of the lighting fixtures, thereby altering the brightness or direction of illumination; or the user controls the switching of the lighting fixtures on and off via the control unit. Furthermore, the front lighting fixtures can be configured with high beam and low beam switching functions. Although garden vehicles are primarily used for working in the nearby garden, they inevitably require some distance lighting; the operating current of the lighting fixtures also changes when switching between high and low beams.

[0286] In another optional embodiment, the control unit is used to adjust the brightness of the lighting lamp. For example, the controller system has multiple brightness control levels for the lighting lamp. When the control unit is operated, it switches between the multiple brightness control levels to achieve the purpose of brightness change. In this embodiment, a single lighting lamp has at least 3 brightness control levels. For example, three brightness levels are configured: 300LM (lumen), 500LM, and 800LM, which can meet the daily use needs.

[0287] In another optional embodiment, the at least two functional mechanisms further include a display area disposed on the steering rod, the display area being used to display a predetermined pattern or text according to the state change of any other functional mechanism; the display area can be configured as a device with display function located at any position on the multi-functional garden vehicle, the aforementioned position including the outer body covering, frame 1, outer contour of the steering rod, step, tires and other parts that can be observed by the user or the outside world.

[0288] The aforementioned display-enabled device can be configured as a lamp board, lamp strip 7, or display screen with a number of LEDs; furthermore, the lamp board or lamp strip 7 can generate functional state changes through color changes or LED flashing, and different frequencies of LED flashing are also considered as functional state changes; the display screen can generate functional state changes through changes in the content it displays.

[0289] In one optional embodiment, the display area is used to change its display effect according to the functional state changes of the walking component. Since the drive wheel has three speed ranges: high, medium, and low, the display area displays different patterns or text when the drive wheel is in different speed ranges. As mentioned above, when the drive wheel switches between high and low speeds, the display area should switch its display state synchronously.

[0290] In another alternative embodiment, the display area can also be used to change its display effect according to the change of the functional state of the cutter bar 8. The cutter bar 8 includes three speed ranges: high, medium, and low. The display area displays different patterns or texts when the cutter is in different speed ranges. As mentioned above, when the cutter switches between high speed and low speed, the display area should switch its display state.

[0291] In another alternative embodiment, the display area is set as the light strip 7 configured on the steering rod. When the speed of the drive wheel or the cutter changes, the color of the light strip 7 also changes. For example, when the speed is relatively low, the light strip 7 displays a relatively soothing color such as green, and when the drive wheel or the cutter bar 8 is at a high speed, the light strip 7 displays a relatively more eye-catching color such as red, so as to remind the user and the people around the vehicle to keep a certain distance from the vehicle.

[0292] In another alternative embodiment, the above-mentioned light strip 7 can also produce a flashing technical effect. For example, when the speed of the drive wheel or the cutter is relatively low, the flashing frequency of the light strip 7 changes. For example, when the speed is relatively low, the light strip 7 flashes at a relatively low frequency, and when the drive wheel or the cutter bar 8 is at a high speed or high load, the light strip 7 flashes at a relatively high frequency, so as to remind the user and the people around the vehicle to keep a certain distance from the vehicle.

[0293] In another alternative embodiment, the above-mentioned light strip 7 can also achieve different patterns by turning on and off local lamp beads inside, such as displaying Chinese characters, English characters, punctuation marks, etc.; for example, when the speed is relatively low, the light strip 7 displays characters such as "safe" or "安全" through the local on and off of lamp beads everywhere inside; when the speed is relatively high, the light strip 7 displays characters such as "危险" or "警告" or "dangerous" or "warning" or "!" that are easily understood as warning meanings. Further, the above characters can also be moved on the light strip 7 by turning on and off the lamp beads inside the light strip 7 for easier observation.

[0294] In another alternative embodiment, several of the color, flashing frequency, and display character change of the above-mentioned light strip 7 can be selected simultaneously, which should not be understood as exceeding the protection scope of this embodiment.

[0295] It should be specifically explained that: when the load of the cutter bar 8 is relatively high, it is generally manifested as the cutter rotating at a high speed, and there may be stones and other sundries on the ground. The high-speed rotating cutter is likely to击飞 stones and cause damage to the surrounding area; the walking components with high load are generally manifested as the lawn mower driving at a high speed; therefore, when the load is relatively high as above, it may cause injury to the people at a relatively close distance. It is particularly necessary for this embodiment to produce a warning effect on the people around through the display component.

[0296] In another optional embodiment, as shown in FIG. 2, the above-mentioned light strip 7 is arranged on the surface of the steering rod and faces the front of the multifunctional garden vehicle. The steering rod includes a first steering rod 2 and a second steering rod 3 respectively located on the left and right sides, and the positions of the two steering rods are relatively close to the outer dimension contour of the garden vehicle. When the garden vehicle of the embodiment travels in an environment with poor night lighting, the light strip 7 can not only inform the outside personnel of the general working condition of the garden vehicle, but also show the general contour of the garden vehicle.

[0297] In another optional embodiment, the display area can also be configured as a screen such as an LED screen, an LCD screen, etc. arranged at various positions of the vehicle, for realizing any function of the above-mentioned light strip 7.

[0298] As mentioned above, when the control is manipulated by the user, the display area changes the display content from the state change according to one kind of function mechanism to the state change according to another function mechanism. That is, the control can change the mapping relationship between the display area and other function components: the display area in a certain state is used to show the high and low speed degree of the cutter, and when the control is manipulated, the mapping relationship is changed to make the display area used to display the fast and slow degree of the running speed.

[0299] In another optional embodiment, the at least two kinds of function mechanisms further include an electric quantity display module which displays different patterns or characters according to the remaining electric quantity of the power supply system 6. Further, the above-mentioned electric quantity display module is an electric quantity display area 415 arranged at the control handle 4. Since the control handle 4 is located at the end of the steering rod, the face of the user standing or sitting on the vehicle faces the control handle 4, and the electric quantity display area 415 is also arranged at the position of the control handle 4 facing the face of the user, so that the user can relatively easily obtain the remaining electric quantity information of the vehicle.

[0300] Further, referring to FIGS. 1, 3, 4 and 8, the electric quantity display area 415 is composed of a plurality of electric quantity display units arranged in the control handle 4.

[0301] In one optional embodiment, the number of electric quantity display units is one, and different remaining electric quantities are shown by different colors displayed by the electric quantity display unit, such as green when the power supply system 6 is in a high electric quantity, yellow when the power supply system 6 is in a medium electric quantity, and red when the power supply system 6 is in a low electric quantity.

[0302] In another alternative embodiment, the power level display area 415 can also be configured to emit red light and green light; when the power system 6 is in full power state, no red light is displayed and the green light is displayed at maximum brightness; when the power level of the power system 6 is almost depleted, no green light is displayed and the red light is displayed at maximum brightness; when the power system 6 is in other states, both colors of light are emitted together and as the power level of the power system 6 is consumed, the brightness of the green light gradually decreases but the brightness of the red light gradually increases; in this embodiment, when the power system 6 is in a state of 50% remaining power, the green light and the red light of the power level display area 415 are both displayed at medium brightness, at which time the two colors of light superimpose on each other so that the user can see yellow light, which conforms to the display effect of displaying power level by color in conventional habits, and the color displayed by the power level display area 415 presents a gradient effect.

[0303] Further, referring again to FIG. 8, the power level display area 415 includes a plurality of power level display units (a single rectangle in the power level display area 415 in the figure is a single power level display unit), and in this embodiment, each power level display unit can be individually illuminated, at which time the number of illuminated power level display units can represent the amount of remaining power, for example, four power level display units are included in the figure, i.e., a single power level display unit represents 25% power, i.e., when one, two, three, or four power level display units are illuminated, the remaining power of the power system 6 is 25%, 50%, 75%, or 100%, respectively.

[0304] In other embodiments, in order to alleviate the power anxiety of the user, the number of illuminated power level display units and the remaining power can also be redefined, for example: when the power is higher than 50%, four power level display units are illuminated; when the power is higher than 25% and less than 50%, three power level display units are illuminated; when the power is higher than 10% and less than 25%, two power level display units are illuminated; when the power is higher than 5% and less than 10%, only one power level display unit is illuminated; and when the power is less than 5%, no power level display unit is illuminated.

[0305] In other embodiments, the power level can also be displayed in different defined ways according to the habits of users in the region.

[0306] In other embodiments, the power level display area 415 can also be configured as a screen, on which the power level information is displayed in various forms such as numerical percentage, color change of battery pattern, and filling area of battery pattern.

[0307] In another alternative embodiment, the multifunctional garden vehicle further comprises an accessory part, which can be a vehicle-mounted fan, a grass collecting fan, a chain saw, a hedge trimmer, etc., and the accessory part is powered by the power supply system 6 of the garden vehicle. The control handle 4 is controlled by the user to change the on-off state of the current of the power supply system 6 to the accessory part; wherein some accessory parts are fixedly assembled at a certain position of the garden vehicle, such as the grass collecting fan arranged near the grass collecting box, and the grass collecting fan generates wind power to transport the cut grass at the cutting platform 8 to the grass collecting box and collect it. Other accessories are placed in the storage box (or tool box) of the multifunctional garden vehicle when not in use, and taken out for use when needed.

[0308] In another alternative embodiment, referring to FIG. 1, a discharge port is arranged on the multifunctional garden vehicle, and the accessory part is electrically connected to the discharge port in a plug-in manner, and the power supply system 6 of the garden vehicle can supply power to the accessory part through the discharge port. In order to facilitate user control, the control handle 4 is controlled by the user to change the on-off state of the current of the power supply system 6 to the accessory part, that is, the vehicle-mounted fan and other accessories can only receive power and start working or start charging the accessory part when the control handle 4 is in the on state.

[0309] Further, in this embodiment, the discharge port arranged on the garden vehicle can be arranged at any position of the vehicle body; FIG. 1 shows that the discharge port is arranged at the power supply system 6, which is only one of the embodiments and should not be understood as a limitation of the protection scope of this embodiment.

[0310] In one of the alternative embodiments, the garden vehicle is further provided with a charging port 9 for charging the power supply system 6, and the discharge port and the charging port 9 share the same interface.

[0311] In another alternative embodiment, the control handle is configured as a control switch, and the control switch comprises at least two states, one of which is equivalent to the aforementioned trigger state, for example, the control switch is a press switch, and its initial state is a non-trigger state, and its pressed state is a trigger state.

[0312] The control panel controls any functional mechanism to produce a functional state change through the controller system when the control switch is in one of the states; for example, when the control handle is used to control the target speed of the grass cutting motor, when the control switch is pressed and is in the trigger state, the target speed of the grass cutting motor is changed.

[0313] In another optional embodiment, the above-mentioned control switch can also be selected as a sliding switch, a rocker switch, a knob switch, etc. The above-mentioned control switch can have multiple trigger states, such as a knob switch with four states, one of which is a non-trigger state, and the other three are trigger states corresponding to different functional states of the functional mechanism. When the above-mentioned knob switch is used to control the target speed of the mowing motor, and the multifunctional garden vehicle in this embodiment has three target speeds, the three trigger states correspond to one of the target speeds respectively. The knob switch as a control switch in this embodiment can be more convenient for users to control. Users can also quickly know the current target speed of the multifunctional vehicle by observing the state of the knob switch. The implementation of the above-mentioned sliding switch and rocker switch is similar to that of the knob switch, and is not described in detail.

[0314] It is particularly pointed out that the above-mentioned control switch is selected as a sliding switch, a rocker switch, a knob switch, etc. All of them at least include one trigger state. When the above-mentioned switch only includes one trigger state, the specific control mode is referred to the above, and is not described in detail.

[0315] In another optional embodiment, a single control handle 4 is configured with two control components: a first control component and a second control component, which are both coupled to the control board, and the control board is coupled to two functional mechanisms: a cutting table 8 and a walking assembly. When the first control component is controlled by the user, the target speed of the cutter in the cutting table 8 is switched. When the second control component is controlled by the user, the speed range of the driving wheel in the walking assembly is switched. In other embodiments, the above-mentioned two functional mechanisms can be any of the previously described functional mechanisms.

[0316] In another optional embodiment, a single control handle 4 is configured with two control components: a third control component and a fourth control component, which are both coupled to the control board, and the control board is coupled to the cutting table 8. When the third control component and the fourth control component are controlled by the user, the cutter in the cutting table 8 is switched to different target speeds. Specifically, when the third control component is controlled by the user, the target speed of the cutter increases; when the fourth control component is controlled by the user, the target speed of the cutter decreases. In other embodiments, the above-mentioned functional structure can be any of the previously described functional mechanisms.

[0317] In another optional embodiment, a single control handle 4 includes one control component, and the control handle 4 of the first steering rod 2 and the second steering rod 3 is respectively configured with a fifth control component and a sixth control component. In this embodiment, the fifth control component and the sixth control component can be used together to control the different functional state changes of one functional mechanism, or respectively control the functional state changes of two functional mechanisms.

[0318] In another optional embodiment, the single control handle 4 includes two or more control handles, and in this embodiment, the control handles at the control handle 4 are collectively coupled to the control board, and the control handles are controlled by the user to generate circuit on-off signals, and the microprocessor arranged on the control board processes the circuit on-off signals generated by the control handles into digital signals or analog signals, and sends them to the controller system uniformly. In comparison with the mode without the control board and the microprocessor, the microprocessor and the controller system in this embodiment can realize communication through the SPI communication, I2C communication, SSI communication, UART serial communication, RS-232 communication, RS-485 communication, CAN communication, LIN communication, infrared communication or Bluetooth communication, etc. Through the above communication modes, the signal transmission efficiency can be effectively improved. If each control handle is individually communicated with the controller system, each control handle needs to be arranged with a signal line 13 connected to the controller system, which not only makes the wiring complicated, but also increases the material cost of the line.

[0319] Further, the single control handle 4 in this embodiment includes two or more control handles, and in this embodiment, the control handles at the control handle 4 are collectively coupled to the microprocessor of the control board, and the microprocessor is connected to the controller system through the wire harness; referring to FIG. 9, the controller system includes the vehicle controller, the cutter controller, the traveling motor controller, the lighting lamp controller, the light strip controller and the power display controller.

[0320] The cutter controller directly controls the speed or torque of the mowing motor, the traveling motor controller directly controls the speed or torque of the traveling motor, the lighting lamp controller directly controls the on-off or brightness of the front or rear lighting lamp, the light strip controller directly controls the on-off of the light strip 7 or the display content of the light strip 7 or the flicker frequency of the light strip 7, etc., and the power display controller directly controls the function switching and on-off of the power display module.

[0321] The above vehicle controller, cutter controller, traveling motor controller, lighting lamp controller, light strip controller and power display controller are coupled to each other, and the above microprocessor is coupled to the vehicle controller through the wire harness.

[0322] In an optional embodiment, as shown in FIG. 8, in this embodiment, the first control handle 414 of the first steering rod 2 includes four positions where the control handles can be arranged, but only three control handles are arranged as described above, and the fourth position of the control handle is configured as the shape of the control handle, and the power display area 415 is arranged at the fourth position of the control handle.

[0332] The power display area 415 is configured to display the remaining power of the power supply system 6. The power display area 415 is arranged on one side of the first control handle 414 close to the free end thereof and above the straight alignment control 416, so as not to block the user's thumb when the user controls other positions on the first control handle 414, that is, the user can effectively obtain the remaining power information of the power supply system 6 at any time.

[0333] The straight alignment control 416 is arranged on one side of the first control handle 414 close to the free end thereof and below the power display area 415, so as to be more convenient for the user to control.

[0337] In another optional embodiment, the control handle 4 is provided with a touch screen 44. The screen of the touch screen 44 can be controlled by the user's touch. The control area on the touch screen 44 is used to control any functional mechanism to change the functional state. The control area is a part of the touch screen 44, and the function thereof can be defined by the user, for example, the original function of a control area is to control the target speed change of the mowing motor, and the user can redefine the control area to control the speed range change of the travel motor. In summary, the touch screen 44 arranged on the control handle 4 can be provided with at least one control area, which can be defined to control any functional mechanism to change the functional state. When the user needs to control another functional mechanism, the control area can be redefined to control the other functional mechanism.

[0339] In one of the optional embodiments, referring to FIG. 16, the touch screen 44 is arranged at the second control handle 42. The display screen is divided into an upper area and a lower area, wherein the upper area is configured as a display area and the lower area is configured as a control area. As shown in the figure, the left side of the display area is used to display the rotating speed of the cutter in the cutting platform 8, and the right side is used to display the driving speed of the vehicle, wherein the unit of the rotating speed is kilo revolutions per minute and the unit of the driving speed is kilometer per hour.

[0340] Referring to FIG. 15 and FIG. 16, the control area includes a setting control with an "M" mark and arrow control, and the setting control and the arrow control cooperate with each other to change the display content of the display area or to realize the operation of the aforementioned control to adjust the function state change of the function mechanism.

[0341] Further, the setting control is used to select the specific function of the arrow control from a plurality of preset optional functions; for example, the preset optional functions of the setting control of the first control handle 41 include: controlling the high beam and low beam mode of the headlamp, or controlling one side of the lamp strip 7 to flash to present the technical effect of the turn signal lamp, or turning on or off one of the function switches, etc.

[0342] The setting control of the second control handle 42 is used to change the specific function of the adjusting button, so that the arrow control selects from a plurality of preset optional functions, and the preset optional functions include: controlling the target rotating speed of the mowing motor, or controlling the rotating speed range of the driving motor, or adjusting the angle deviation threshold value, or adjusting the preset field intensity threshold value, or adjusting the preset signal intensity threshold value, etc.

[0343] Further, in the embodiments of the control handle 4 with the touch screen 44, the control area and the display area can also be configured in other various embodiments, such as displaying a scroll wheel-shaped pattern in the control area, and the user can realize the adjustment of any function mechanism by sliding the touch screen 44 at the scroll wheel-shaped pattern, etc. Those skilled in the art can configure the control area and the display area in other embodiments without creative labor, and all of them should be included in the protection scope of the present application.

[0344] In the embodiment of the control handle 4 configured with the touch screen 44, the touch screen 44 should be coupled with the control board, and the display area and the control area of the touch screen 44 are directly controlled by the microprocessor on the control board. The microprocessor is connected with the vehicle controller of the controller system, so that the vehicle controller can control the various functional mechanisms of the garden vehicle.

[0345] The edge of the touch screen 44 should be waterproofed by means of edge sealing or the like, so as to avoid damage to the touch screen 44 and the control board due to water.

[0346] Those skilled in the art should understand that the touch screen 44 for changing the functional state of the functional mechanism can also be configured at other parts of the vehicle, such as a position closer to the user.

[0347] In another optional embodiment, referring to FIG. 17 and FIG. 18, a thin film switch 43 can also be configured on the surface of the control handle 4. The thin film switch 43 includes a deformation layer 432 and a circuit layer 431. The circuit layer 431 is printed with a circuit, and the deformation layer 432 is configured to be partially protruded and not in direct contact with the circuit layer 431. The protruded deformation layer 432 is provided with a conductive block 433. The partially protruded deformation layer 432 is deformed under pressure to make the conductive block 433 in contact with the circuit layer 431.

[0348] The circuit printed on the circuit layer 431 is electrically disconnected at the position corresponding to the conductive block 433. When the deformation layer 432 is pressed to make the conductive block 433 in contact with the circuit layer 431, the circuit at the corresponding position is turned on. The working principle of the thin film switch 43 is that the deformation layer 432 is pressed to change the circuit layer 431 from the disconnected state to the turned-on state. That is, the working principle of a single control element in the thin film switch 43 in this embodiment.

[0349] Referring again to FIG. 17, the thin film switch 43 at the control handle 4 of the first steering rod 2 and the second steering rod 3 is configured with five control elements, which are used to control the functional state change of the functional mechanisms of the garden vehicle. Specifically, each control element of the thin film switch 43 can be freely defined as the function of any of the aforementioned control elements, so as to change the functional state of the functional mechanisms.

[0350] The circuit layer 431 should be connected with the control board of the control handle 4 through a wire harness, and connected with the vehicle controller of the controller system through the microprocessor of the control board, so that the vehicle controller can control the various functional mechanisms of the garden vehicle.

[0351] In another alternative embodiment, referring to FIG. 4 and FIG. 5, the control handle 4 comprises a box-shaped structure configured with a control panel and control knobs, the box-shaped structure is provided with a through hole, the control panel and the control knobs are sequentially abutted to the side wall of the box-shaped structure from inside to outside, the control knobs at the matching position of the through hole are made of flexible material to realize sealing at the through hole; the user controls the control knobs at the through hole to make the control panel control the at least one functional mechanism to produce a functional state change. In this embodiment, the box-shaped structure is made of hard material, and the through hole is provided to enable the user to control the control knobs through the through hole.

[0352] Further, referring again to FIG. 4 and FIG. 5, the box-shaped structure in the figure is provided with four through holes for facilitating the user to control the control knobs, and the four control knobs controlled by the user are configured as an integrated control assembly, which can reduce the risk of water leakage at the through hole and the like. Specifically, the first control handle 414 is provided with four control knobs, and the four control knobs are configured as a first control assembly 4121 in an integrated structure. The second control handle 42 is provided with four control knobs, and the four control knobs are configured as a second control assembly 4221 in an integrated structure.

[0353] Further, in another embodiment, taking the second control handle 42 as an example: referring again to FIG. 5, FIG. 6 and FIG. 7, the second control assembly 4221 comprises a second functional control knob 42214 integrated in a second control panel 4222 and a second sealing control part abutting to the through hole, and the second control panel 4222 and the second sealing control part are sequentially abutted to the side wall of the box-shaped structure from inside to outside; and the second sealing control part is made of flexible material, which not only produces the sealing effect as described above, but also can be deformed to transmit the control force to the second functional control part when controlled by the user, thereby realizing the control of the functional mechanism to produce a functional state change. The first control handle 414 can use the same technical means to realize, which will not be described herein.

[0354] Further, referring to FIG. 6, in one of the alternative embodiments, as described above, the second control handle 42 is provided with four control knobs, each of which can be individually controlled by the user, and the four control knobs are configured as a second control assembly 4221 in an integrated structure. Correspondingly, the second sealing control part comprises a second sealing control panel body 42211 and a second sealing control knob 42212; the second sealing control part in the figure comprises four second sealing control knobs 42212. Further, the second sealing control knob 42212 is integrated on the second sealing control panel body 42211, and a second separation groove 42215 is provided between each second sealing control knob 42212, that is, the second separation groove 42215 is provided on the second sealing control panel body 42211.

[0355] Further, referring to FIG. 6, FIG. 19, FIG. 20, the second sealing control plate body 42211 is provided with a plurality of second partition grooves 42215, and the plurality of second partition grooves 42215 are in communication with each other.

[0356] In the figure, the second partition grooves 42215 reduce the thickness of the second sealing control plate body 42211 between two second sealing control areas, and when one of the second sealing control areas is pressed by the user, the second sealing control area deforms and moves downward, which produces a pulling effect on the surrounding position. As described above, the thickness of the second sealing control plate body 42211 at the partition groove is significantly reduced, so that when the second partition groove 42215 is pulled, a larger deformation amount is easily generated, and the thickness of the second sealing control area is larger, which is not easy to generate a larger deformation amount.

[0357] In summary, when one of the sealing control areas is pressed and moves downward, a pulling force is generated on the adjacent position of the sealing control plate body, which causes a larger deformation amount at the partition groove, thereby avoiding the adjacent first sealing control area from being significantly deformed. That is, when one of the sealing control areas is pressed, the adjacent sealing control area is also pressed. Further, the pressure required for pressing a single sealing control area is also reduced.

[0358] Further, as shown in FIG. 6, the second sealing control plate body 42211 is provided with a second control plate hole 42213 for mounting the second sealing control plate body 42211 to the corresponding control handle 4; as shown in FIG. 7, the second control plate 4222 is provided with a second control plate hole 4223 for mounting the second control plate 4222 to the corresponding control handle 4.

[0359] When assembling the second control handle 42, the second sealing control plate body 42211 and the second control plate 4222 are abutted to the through hole of the shell of the control handle 4, and a bolt is sequentially threaded through the second control plate hole 4223 and the second control plate hole 42213 and connected with the bolt hole at the shell, thereby realizing the mounting of the control plate and the control handle, and realizing the sealing of the through hole.

[0360] Again referring to FIG. 6, in an optional embodiment, each second partition groove 42215 is connected with each other and extends to the edge of the second sealing control plate body 42211, and each second partition groove 42215 is provided with a second control plate hole 4223 near the edge of the sealing plate body, and a bolt is threaded through the control plate hole 4223 at the partition groove and produces a pressing effect, thereby avoiding the external water vapor from entering the inner wall of the control handle 4 through the edge of the partition groove, and realizing an effective sealing effect.

[0361] In another optional embodiment, the first control handle 414 is also provided with the above-mentioned sealing control structure and functional control structure, which is not described herein.

[0362] In summary, in this embodiment, the control panel and microprocessor arranged in the control handle 4 process the signals of the control elements, and communicate with the controller system, avoiding arranging many signal lines connecting the control elements and the controller system, simplifying the wiring difficulty, reducing the material cost, and facilitating the reduction of the size of the control handle 4 and the steering rod.

[0363] For the same purpose, in another aspect, the embodiments of the present specification also provide a riding mower, which comprises a vehicle frame 1, a mowing deck 8, a walking assembly, a seat 5, a power supply system 6; the seat 5 is arranged on the vehicle frame 1 and is used for a user to sit on, and the steering rod and the control handle 4 are arranged in front of the seat 5, so that the user can hold the steering rod relatively easily when sitting on the seat 5 and raising the arms forward with the arms naturally stretched out.

[0364] For the same purpose, in another aspect, the embodiments of the present specification also provide a standing mower, which comprises a vehicle frame 1, a mowing deck 8, a walking assembly, a standing platform, a power supply system 6; the standing platform is arranged on the vehicle frame 1 and is used for a user to stand on, and the steering rod and the control handle 4 are arranged in front of the standing platform, so that the user can hold the steering rod relatively easily when standing on the standing platform and raising the arms forward.

[0365] For the same purpose, in another aspect, the embodiments of the present specification also provide a multifunctional work vehicle, which comprises at least a vehicle frame, at least two functional mechanisms, a power supply system, a controller system, and an active steering assembly.

[0366] The functional mechanisms are used to perform specific functions of the multifunctional work vehicle, the power supply system 6 is used to supply power to the functional mechanisms, the controller system is used to control at least one functional mechanism to generate a functional state change, and the active steering assembly is operatively coupled to the walking assembly of the multifunctional work vehicle and is used to generate a speed difference between the driving wheels on both sides to make the multifunctional work vehicle turn.

[0367] The active steering assembly comprises a control handle held and operated by a user, and the control handle is arranged with a control panel and at least two control elements coupled to the control panel; the signals generated by the operation of the at least two control elements are transmitted to the controller system after being integrated by the control panel, so that the controller system controls the functional mechanisms to generate a functional state change.

[0368] The at least two functional mechanisms comprise an outdoor work component connected to the vehicle frame and a walking assembly, the outdoor work component is used for outdoor work, and the walking assembly is drivingly connected to the driving wheels on both sides of the vehicle frame and is used to drive the multifunctional work vehicle to travel.

[0369] It can be understood that in some optional embodiments, the outdoor working components of the multifunctional working vehicle described above can also be replaced by other components, such as sweeping, snow sweeping, snow shoveling, flushing, bucket, or components for grabbing and carrying goods, so that the lawn mower is adaptively changed into a corresponding tool vehicle, such as a sweeper, a snow sweeper, a snow shoveling machine, a flushing machine, a forklift, a carrier, etc. Those skilled in the art should be able to adaptively replace various functional components without creative labor, and the above should be included in the protection scope of the present embodiment.

[0370] In one of the optional embodiments, the battery compartment is detachably arranged on the vehicle frame, and the battery pack is contained in the battery compartment, that is, the battery compartment can be separated or combined with the vehicle frame as a whole.

[0371] In one of the specific optional embodiments, the vehicle frame is provided with a power supply interface, the battery compartment is hung on the vehicle and electrically connected with the power supply interface, and the battery compartment as a whole can be detached, so that the user can complete the replacement of all battery packs at the fastest speed, that is, when it is necessary to supplement the power of the vehicle by replacing the battery pack, the whole battery compartment has higher efficiency.

[0372] The multifunctional garden vehicle described above further comprises a positive steering assembly operatively coupled to the walking assembly of the multifunctional garden vehicle for causing the driving wheels on the left and right sides to produce a speed difference to make the garden vehicle rotate. That is, the positive steering assembly can actively cause the driving wheels on the left and right sides to produce a speed difference when controlled by a person, rather than causing the driving wheels to produce a speed difference when the vehicle is driven by an external force.

[0373] The garden vehicle described above further comprises a controller system capable of controlling the functional mechanisms and causing the functional state changes.

[0374] The positive steering assembly in the present embodiment further comprises a control handle 4 for a user to hold and operate, and the control handle 4 is provided with a control board and at least two operation controls coupled to the control board. A single operation control can be used to control one of the functional mechanisms and cause the functional state change, and the signals generated by the at least two operation controls are transmitted to the controller system after being integrated by the control board, so that the controller system controls the functional mechanisms to produce the functional state changes.

[0375] The operation controls generate control instructions when operated by the user, and the instructions are information for causing one of the functional mechanisms to produce a functional state change; and different operation controls should be able to issue different instructions. In the present embodiment, the control board can respond to the instructions of the at least two operation controls, integrate the instructions of the two operation controls, and then send signals to the controller system.

[0376] Further, the at least two control handles emit independent signals, and the control panel combines the independent signals into a composite signal capable of being transmitted on the same channel and sends the composite signal to the control panel. Common methods include frequency division multiplexing, code division multiplexing, time division multiplexing, etc.

[0377] Since the integrated signal can be transmitted on the same channel, the wire harness for transmitting the signal can be greatly reduced, solving the technical problem caused by the large number of wire harnesses and terminal posts. Further, the more control handles of the control handle 4 or the more types of signals that the control handles can send, the more wire harnesses that can be reduced, and the more obvious the technical effect.

[0378] The present specification also provides another alternative embodiment, which discloses a multifunctional garden vehicle including a vehicle frame 1, a function mechanism, a power supply system 6, a controller system, a steering lever, etc.

[0379] The function mechanism includes garden operation components, walking assemblies, and other components configured on the vehicle frame 1 and used to perform specific functions of the multifunctional garden vehicle. Specifically, the garden operation components are used for garden operation, and the walking assemblies are drivingly connected to the driving wheels on both sides of the vehicle frame 1 to drive the multifunctional garden vehicle to travel and turn.

[0380] The power supply system 6 is configured on the vehicle frame 1 and is used to supply power to the function mechanism, etc. The whole vehicle control system is configured on the vehicle frame 1 and is used to control at least one function mechanism to change the function state. The steering lever is controlled to rotate around a first axis 15 parallel to the left-right direction of the vehicle.

[0386] In one of the optional embodiments, referring to FIG. 25, the wire slot is arranged on the side wall of the pressing plate 12 close to the steering rod, and only a continuous slot needs to be processed on the pressing plate 12, so the manufacturing is more convenient. In other embodiments, the wire slot can also be arranged on the steering rod.

[0387] Referring to FIG. 22 and FIG. 23, the frame 1 is fixedly provided with a mounting plate 14, and the mounting plate 14 is provided with a retaining member for fixing part of the signal line 13. As described above, part of the signal line 13 is fixed to the steering rod by the wire slot and the pressing plate 12, and the steering rod and the steering rod maintain a relatively fixed positional relationship; the other part of the signal line 13 is fixed to the mounting plate 14 by the retaining member, and the mounting plate 14 and the frame 1 maintain a relatively fixed positional relationship. The signal line 13 is thus divided into a frame line part fixed to the frame 1, a steering rod line part fixed to the steering rod, and a free line part between the frame line part and the steering rod line part. The aforementioned retaining member position is the demarcation position of the free line part and the frame line part.

That is, part of the signal line 13 on one side of the wire hole 143 is the free line part, and the other side of the wire hole 143 is the frame line part. Further, the mounting plate 14 is also provided with a mounting hole 144 close to the wire hole 143, and the retaining member is a strap (not shown) that penetrates the mounting hole 144 and the wire hole 143 and binds the signal line 13.

[0389] Further, as described above, the steering rod rotates around the first axis 15 between the first forward position, the intermediate position, and the first backward position, that is, the steering rod line part of the signal line 13 rotates with the steering rod around the first axis 15 and produces relative movement with the frame line part; the free line part in the intermediate position is used to always connect the signal of the steering rod and the controller system during the rotation of the steering rod around the first axis 15.

[0390] In one of the optional embodiments, the free wire portion is at least partially spaced apart from the first axis 15 by a distance less than 100 mm. The relatively small distance makes the steering rod reduce the amount of movement of the free wire portion when the signal wire 13 is rotated with the steering rod during rotation of the steering rod about the first axis 15, i.e. the free wire portion only needs to reserve a relatively small length allowance to meet the rotation of the steering rod about the first axis 15, and the problem that the free wire portion is straightened or the steering rod is restricted from rotating when the steering rod is rotated to a certain position about the first axis 15 does not occur.

[0391] In another optional embodiment, the free wire portion is combined with the frame wire portion at a position spaced apart from the first axis 15 by a distance less than 100 mm, i.e. the distance between the retaining member and the first axis 15 is less than 100 mm.

[0392] In another optional embodiment, the free wire portion is combined with the frame wire portion at a position spaced apart from the first axis 15 by a distance less than 50 mm, i.e. the distance between the retaining member and the first axis 15 is less than 50 mm. As shown in the figure, the first axis 15 is provided with a shaft for rotating the steering rod about the first axis 15, and the retaining member is spaced apart from the shaft to avoid interference between the signal wire 13 and the shaft, and therefore the distance between the retaining member and the first axis 15 is configured to be less than 50 mm to better achieve the above technical effect.

[0393] Referring to FIG. 25, d1 in the figure is the distance between the retaining member and the first axis 15. When d1 = 50 mm, the maximum angle of the steering rod deviating from the middle position in the front-rear direction is 20°, and the free wire portion is at least reserved a first reserved length for movement about the first axis 15. The first reserved length is the arc length of a circle with a radius of 50 mm and a central angle of 20°, and the calculated first reserved length is 17.5 mm.

[0394] Referring to FIGS. 23 and 25, the circle in the hole 143 in FIG. 23 is a cross section of the signal wire 13 at the position, and in FIGS. 23 and 25, the reference numeral 15 indicates the first axis 15. The distance between the above cross section and the first axis 15 is the distance between the free wire portion and the first axis 15.

[0395] Referring to FIG. 21, in one of the optional embodiments, the steering rod also rotates about a second axis 16 in the left-right direction of the vehicle, and the second axis 16 is parallel to the forward direction of the vehicle. The direction in which the steering rod rotates about the second axis 16 is indicated by the arrowed arc in FIG. 22. Specifically, the steering rod is configured such that when it moves to the outside of the vehicle about the second axis 16, the vehicle is in a parking state, and the steering rod cannot rotate about the first axis 15 at this time. When the steering rod moves to the inside of the vehicle about the second axis 16, the vehicle is in a drivable state, and the steering rod can rotate about the first axis 15 at this time.

[0396] In one of the optional embodiments, the free wire portion is at least partially spaced apart from the second axis 16 by a distance less than 100 mm. The relatively small distance allows the steering rod to rotate around the second axis 16, and reduces the movement of the free wire portion of the signal wire 13 when the steering rod rotates, i.e. the free wire portion only needs to reserve a relatively small length to meet the rotation of the steering rod around the second axis 16, and the problem of the free wire portion being straightened or even limiting the rotation of the steering rod when the steering rod rotates to a certain position around the second axis 16 does not occur.

[0397] In another optional embodiment, the joint of the free wire portion and the rod wire portion is spaced apart from the second axis 16 by a distance less than 100 mm, i.e. the minimum distance between the pressing plate 12 and the second axis 16 is less than 100 mm.

[0398] In another optional embodiment, referring to FIG. 25, the joint of the free wire portion and the rod wire portion is spaced apart from the second axis 16 by a distance less than 50 mm, i.e. the distance between the pressing plate 12 and the second axis 16 is less than 50 mm. As shown in FIG. 21, the second axis 16 is provided with a shaft for rotating the steering rod around the second axis 16, and the holder is spaced apart from the shaft to avoid interference between the signal wire 13 and the shaft, so the distance between the holder and the second axis 16 is configured to solve the problem of being less than 50 mm to better achieve the above technical effects.

[0399] Referring to FIG. 25, d2 in the figure is the distance between the pressing plate 12 and the second axis 16. When d2=50 mm, the maximum angle of the steering rod deviating from the middle position in the front-rear direction is 35°, and the length of the free wire portion moving around the second axis 16 is at least a second reserved length. The second reserved length is the arc length of a circle with a radius of 50 mm and a central angle of 35°, and the calculated second reserved length is 27.9 mm.

[0400] Further, in one of the optional embodiments, the steering rod can only deflect outwardly around the second axis 16 when the steering rod moves to the middle position around the first axis 15, and the signal wire 13 is in an initial state when the steering rod is in the middle position, so it is not necessary to reserve both the first reserved length and the second reserved length, i.e. only the second reserved length needs to be reserved to meet the normal deflection of the steering rod under the above conditions.

[0401] When the reserved length of the signal wire 13 is selected to be greater than 27.9 mm, such as 28.5 mm, the shaking of the signal wire 13 during vehicle operation is relatively limited, and even if there is a small amount of friction with the vehicle frame 1, the friction position is easy to control, and at this time only protective measures such as a protective sleeve need to be added at the corresponding position, and the overall friction amount is relatively controllable and will not cause serious wear or even communication breakage due to shaking of the signal wire 13.

[0402] Further, in another alternative embodiment, the above-mentioned d1 and d2 can be further reduced, so that the length of the required reserve is further shortened, and the amount of jitter generated by the signal line 13 during vehicle operation is smaller, and the problem of signal line 13 jitter wear caused by the length of the reserve can be avoided.

[0403] In another alternative embodiment, referring to FIG. 27, the free line portion of the signal line 13 is wound into a spiral line portion 17. The spiral structure of the spiral line portion 17 makes it elastic, and when it is stretched, it can significantly elongate to ensure that the free line portion has a significant length allowance; when it is not stretched, it can be shortened to occupy less space and reduce the probability of interference with other parts of the vehicle.

[0404] In the embodiment in which the free line portion is wound into a spiral line portion 17, the distance between the free line portion and the first axis 15 is the shortest distance between the two.

[0405] In summary: in the embodiment in which the control member transmits signals to the controller system through the signal line 13, the arrangement of the signal line 13 is disclosed in the present specification to avoid interference between the signal line 13 and the frame 1 and other components caused by the movement of the steering lever. Specifically, by limiting the position of the free line portion relative to the rotation axis of the steering lever, the movement of the free line portion during rotation of the steering lever is smaller, thereby avoiding the free line portion of the signal line 13 from generating large movements or even interfering with the frame 1 and other components during rotation of the steering lever. Further, it also avoids the occurrence of problems such as severe wear of the signal line 13 during long-term use of the garden vehicle.

[0406] In another alternative embodiment, referring to FIG. 1, the garden vehicle disclosed in the present embodiment further comprises a seat 5 for carrying a user. When driving the garden vehicle, the user sits on the seat 5 and holds the steering lever to drive the vehicle. During driving, the control member on the steering lever is controlled according to the needs, thereby changing the functional state of the certain functional mechanism.

[0407] Further explanation: in the above-mentioned embodiment in which the signal line 13 is connected to the controller system, the controller system for realizing the functional state change of the control function mechanism is a prior art, which can transmit signals in a conventional communication mode, and thus no further explanation is given here.

[0408] Further, referring to Fig. 1, the garden working component in the above embodiment is shown in the driving of the mowing deck 8, and the multifunctional garden vehicle in the embodiment is a mower. In addition, if the garden working component is a snow sweeping component, the multifunctional garden vehicle is a snow sweeper. That is, the garden working component as the main functional component of the multifunctional garden vehicle can be changed according to the selection of the user. Meanwhile, in some embodiments, the garden working component can also be a component replaced by the user according to the actual needs, such as the mowing deck 8 used for mowing is disassembled and replaced by a sweeping disc used for sweeping, so as to change the mower into a sweeper. In summary: the garden working component is replaced by any functional component according to the user's needs, which should not be understood as breaking the protection scope of the embodiment.

[0409] For the same purpose, in another aspect, the embodiment of the present specification also provides a riding mower, which comprises a vehicle frame 1, a mowing deck 8, a walking assembly, a seat 5, a power supply system 6; the seat 5 is arranged on the vehicle frame 1 and used for the user to sit, a steering lever and a control handle 4 are arranged in front of the seat 5, and the steering lever can rotate around a first axis 15 parallel to the left-right direction of the vehicle. When the user sits on the seat 5 and raises the arm forward, the arm can be naturally stretched, and the steering lever can be held relatively easily.

[0410] For the same purpose, in another aspect, the embodiment of the present specification also provides a standing mower, which comprises a vehicle frame, a mowing deck, a walking assembly, a standing platform, a power supply system 6; the standing platform is arranged on the vehicle frame and used for the user to stand, a steering lever and a control handle 4 are arranged in front of the standing platform, and the steering lever can rotate around a first axis 15 parallel to the left-right direction of the vehicle. When the user stands on the standing platform and raises the arm forward, the arm can be naturally stretched, and the steering lever can be held relatively easily.

[0411] For the same purpose, in another aspect, the embodiment of the present specification also provides a multifunctional working vehicle, which comprises a vehicle frame 1, a functional mechanism, a controller system, a steering lever, etc. The steering lever can rotate around a first axis 15 parallel to the left-right direction of the vehicle. When the user holds and deflects the steering lever, the vehicle driving or steering can be controlled.

[0412] In the above-mentioned embodiments of the riding mower, the standing mower and the multifunctional working vehicle, the aforementioned steering lever and the signal line are included, the signal line comprises a vehicle frame line part fixed on the vehicle frame, a steering lever line part fixed on the steering lever, and a free line part between the vehicle frame line part and the steering lever line part; and the free line part is at least partially spaced apart from the first axis by less than 100 mm, so as to achieve the simple arrangement of the signal line and avoid the interference between the signal line and the vehicle frame and other components during the rotation of the steering lever.

[0413] In summary: in some embodiments of the present application, by limiting the distance between the free wire portion of the signal line 13 and the rotation shaft of the steering rod, the required length of the free wire portion is reduced, thereby avoiding the relative limited shaking of the vehicle during operation, even if there is a small amount of friction between the vehicle frame 1 and the steering rod, the friction position is easy to control, and at this time only the protective measures such as the protective sleeve need to be added at the corresponding position, and the overall friction amount is relatively controllable and will not cause the situation of serious wear and even communication breakage due to the shaking of the signal line 13.

[0414] The present application also provides another optional embodiment, which discloses a multifunctional garden vehicle, comprising: a vehicle frame 1, a function mechanism, a power supply system 6;

[0415] The function mechanism is used to perform a specific function of the multifunctional garden vehicle; the power supply system 6 is arranged on the vehicle frame 1 and is used to supply power to the function mechanism; and the whole vehicle control system is arranged on the vehicle frame 1 and is used to control at least one function mechanism to change the function state. The steering rod is controlled to rotate around the first axis 15, which is parallel to the left-right direction of the vehicle.

[0416] The function mechanism at least includes a garden operation component and a walking assembly, the garden operation component is connected to the vehicle frame 1 and is used to perform garden operation; and the walking assembly is arranged on the vehicle frame 1, the walking assembly is drivingly connected to the driving wheels on both sides of the vehicle frame 1, and is used to drive the multifunctional garden vehicle to travel.

[0417] The multifunctional garden vehicle further comprises an active steering assembly, which is operatively coupled to the walking assembly of the multifunctional garden vehicle, and is used to generate a speed difference between the driving wheels on both sides to realize the turning of the garden vehicle.

[0418] In addition, referring to FIG. 28, the active steering assembly is provided with a tool-free display screen. That is, the user can manually disassemble the display screen without the aid of tools. The disassembled display screen can be freely disposed by the user, giving the user higher control freedom of the garden vehicle.

[0419] In one optional embodiment, the display screen is a touch screen 44 that can be controlled by the user's touch, and the touch screen 44 changes the function state of the function mechanism when controlled by the user. For example, by controlling the touch screen 44, the working mode of the garden operation component is changed.

[0420] In one of the optional embodiments, referring to FIG. 1, FIG. 2, and FIG. 3, the active steering assembly is configured as a steering lever, which is pivoted to the vehicle frame 1 and the deflection angle of the steering lever is positively correlated with the rotation speed of the driving motor. The steering lever can be deflected forward or backward around a first axis 15 on the vehicle frame 1, and the steering lever has a first forward position deflected to the most forward position, a first backward position deflected to the most backward position, and an intermediate position. The first axis 15 is parallel to the left-right direction of the vehicle.

[0421] Specifically, when the steering lever is in the intermediate position, the driving motor does not drive the driving wheel to rotate, and at this time the vehicle is in a stationary state. When the steering lever is in the first forward position, the real-time rotation speed of the driving motor is equal to the maximum rotation speed of the current speed range. When the steering lever is between the intermediate position and the first forward position, the real-time rotation speed of the driving motor is less than the maximum rotation speed of the current speed range, and when the steering lever continues to be deflected to the first forward position, the real-time rotation speed of the driving motor increases.

[0422] Referring to FIG. 1, the steering lever includes a control handle 4 for a user to hold, and the display screen is arranged on the side of the control handle 4 where the user's thumb is located when holding the control handle 4. Thus, the user can easily control the display screen by the thumb, and the position close to the thumb is also relatively closer to the front of the user, so that the user does not need to significantly change the direction of his / her line of sight when observing the display screen, thereby reducing the user's work burden caused by observing and operating the display screen.

[0423] Referring to FIG. 28 and FIG. 30, the first signal connection port 4501 is arranged at the position of the control handle 4 matched with the display screen; correspondingly, referring to FIG. 29, the second signal connection port 4502 is arranged at the display screen, and the two ports are matched with each other to realize the communication between the display screen and the garden vehicle. As shown in the figure, the second signal connection port 4502 shown in the figure is a male head of Type-C, and the first signal connection port 4501 is a female head of Type-C. When the display screen is assembled to the control handle 4, the first signal connection port 4501 is matched inside the second signal connection port 4502 to realize the communication between the two. At the same time, since the power consumption of the display screen is small, the vehicle can also supply power to the display screen through the Type-C port.

[0424] In addition, in another optional embodiment, a female head of Type-C is arranged at the display screen, and a male head of Type-C is arranged at the control handle 4, so as to ensure that the outer surface of the side of the display screen is not obviously convex, and the display screen can be stably placed on a plane when it is detached.

[0425] In another optional embodiment, the multifunctional garden vehicle further comprises a wireless signal module connected to the display screen through a wireless signal, and the display screen is connected to the function mechanism through the wireless signal module. Specifically, the wireless signal module can be implemented as one or more of infrared communication, wireless local area network (Wi-Fi), near field communication (NFC), radio frequency identification (RFID), Bluetooth, etc., for the display screen to communicate with each function mechanism of the vehicle.

[0426] Further, the first signal connection port 4501 and the second signal connection port 4502 can also be other commonly used USB interfaces, etc., and those skilled in the art can replace the Type-C interface of the control handle 4 and the display screen with various signal connection ports without creative labor, which should all be included in the protection scope of the present embodiment.

[0427] Referring to FIG. 1, the garden operation component in the present embodiment is a mowing deck 8 connected to the vehicle frame 1, and the mowing deck 8 comprises a rotary cutter for mowing grass. In other embodiments, the garden operation component can also be a component with snow sweeping, snow blowing, snow shoveling, flushing, and shovel functions, or a component for grabbing and carrying goods to assist construction during garden operation. Those skilled in the art can replace the operation assembly in the present embodiment with various functional components without creative labor, which should all be included in the protection scope of the present embodiment.

[0428] As described above, when the garden operation component is the mowing deck 8, the multifunctional garden vehicle is a mower; further, when the garden operation component is a snow sweeping component, the multifunctional garden vehicle is a snow sweeper; that is, the garden operation component as the main functional component of the multifunctional garden vehicle can be changed according to the user's selection; at the same time, in some embodiments, the above-mentioned garden operation component can also be a component replaced by the user according to actual needs, such as removing the mowing deck 8 for mowing and replacing it with a sweeping disc for sweeping, which changes the mower into a sweeper; in summary: the garden operation component is replaced by any functional component according to user needs, which should not be understood as beyond the protection scope of the present embodiment.

[0429] In an optional embodiment, referring to FIG. 28 and FIG. 30, the control handle 4 is provided with a mounting groove 4503 for accommodating the display screen, and the display screen assembled in the mounting groove 4503 not only has a limiting effect, but also effectively reduces or eliminates the display screen protruding from the surface of the control handle 4, reducing the force of the external device or the user touching the side of the display screen to make the display screen outwardly separate from the control handle 4;

[0430] In an alternative embodiment, referring to FIG. 28 and FIG. 29, a clamping groove 4504 is formed in the mounting groove 4503, the display screen is provided with a clamping block 4505 which cooperates with the clamping groove 4504, and the control handle 4 is provided with an unlocking member which is operated by the user to release the cooperation between the clamping block 4505 and the clamping groove 4504.

[0431] When the clamping block 4505 cooperates with the clamping groove 4504, the clamping groove 4504 limits the clamping block 4505 to prevent the display screen from being separated from the mounting groove 4503, thereby reliably assembling the display screen on the control handle 4.

[0432] In an alternative embodiment, referring to FIG. 31 and FIG. 32, a locking block 4506 is arranged in the clamping groove 4504, and the locking block 4506 abuts against the clamping block 4505 when the clamping block 4505 cooperates with the clamping groove 4504 to prevent the display screen from being separated from the mounting groove 4503. That is, the locking block 4506 is a component for limiting the clamping block 4505. Specifically, the clamping block 4505 has an abutting surface which is perpendicular to the extending direction of the clamping groove 4504, and when the clamping block 4505 is inserted into the clamping groove 4504, the abutting surface of the clamping block 4505 abuts against the locking block 4506 to prevent the clamping block 4505 from being separated from the clamping groove 4504 along the extending direction of the clamping groove 4504.

[0433] Further, the clamping block 4505 has a certain elasticity, and the elastic force enables the clamping block 4505 to move towards the locking block 4506, thereby keeping the abutting surface of the clamping block 4505 abutting against the locking block 4506.

[0434] In an alternative embodiment, referring to FIG. 32, a partial cross-sectional view of the control handle 4 is shown, and the specific structure of the unlocking member is shown. As shown in the figure, the unlocking member includes a top rod 4507 and a reset member 4508. The top rod 4507 is movably connected to the control handle 4, and is used to separate the locking block 4506 from the clamping block 4505 when the top rod 4507 is operated by the user. Specifically, the top rod 4507 moves downward and presses the clamping block 4505 when the top rod 4507 is operated by the user, until the clamping block 4505 is separated from the locking block 4506. At this time, the locking block 4506 loses the locking effect on the clamping block 4505, and the display screen can be removed from the control handle 4.

[0435] Further, referring to FIG. 32, the locking block 4506 is provided with an unlocking hole 45061 through which the top rod 4507 penetrates. When the unlocking member is not operated by the user, the end of one side of the top rod 4507 is located in the unlocking hole 45061. When the unlocking member is operated by the user, the top rod 4507 moves along the through hole and presses the clamping block 4505. The unlocking hole 45061 can guide the top rod 4507 to avoid the situation that the top rod 4507 cannot effectively abut against the clamping block 4505 when the unlocking member is operated by the user.

[0436] The reset member 4508 is connected to the jacking rod 4507, and is used to automatically reset the jacking rod 4507 to the initial state. As described above, when the unlocking member is not manipulated by the user, the end of the jacking rod 4507 on one side is located in the through hole and does not produce a pressing effect on the clamping block 4505. In this embodiment, the reset member 4508 with elasticity is configured, which is deformed and pushes the jacking rod 4507 to move when it is pressed, and is reset under the action of its own elasticity when it is not pressed. Further, the reset member 4508 should be made of a material with good elasticity, such as plastic or metal sheet.

[0437] Further, referring again to FIG. 32, the unlocking member in this embodiment further includes a protective layer 4509 and a pad 4510. The protective layer 4509 is configured on the outer wall of the control handle 4, and is used to prevent external water vapor from entering the inside of the control handle 4 through this place. The pad 4510 is configured between the protective layer 4509 and the reset member 4508, and is used to transmit the manipulation of the user on the protective layer 4509 to the reset member 4508, so as to realize effective manipulation of the reset member 4508.

[0438] In another optional embodiment, the control handle 4 is provided with a mounting groove 4503 for accommodating the display screen, and the mounting groove 4503 is provided with an elastic member 4511. The elastic member 4511 generates an elastic force on the display screen when the display screen is arranged in the mounting groove 4503, and the elastic force is a pushing force for moving the display screen outward. The pushing force can keep the abutting surface of the clamping block 4505 in abutment with the locking block 4506. At the same time, the presence of the elastic member 4511 can also avoid the display screen from shaking in the mounting groove 4503, that is, it can avoid the case that the display screen is frequently shaken in the mounting groove 4503 to hit the inner wall of the mounting groove 4503 and is damaged.

[0439] In another optional embodiment, referring to FIG. 30, the side of the display screen is provided with a belt 4512 for assembling the display screen to the control handle 4. When the display screen is arranged in the mounting groove 4503 of the control handle 4, the belt 4512 can form an annular structure wrapping the control handle 4, and the size of the annular structure can be manually manipulated by the user. When the user manually manipulates the belt 4512 to increase the size of the annular structure, the display screen can be smoothly taken off from the control handle 4. Conversely, the user places the display screen at the corresponding position of the control handle 4 and reduces the size of the annular structure of the belt 4512, so as to fix the display screen to the control handle 4.

[0440] In one of the optional embodiments, the band 4512 is composed of two half bands 4513, which are fixed to the side walls of the display screen respectively, and the free ends of the two half bands 4513 are provided with connecting members which can be buckled to each other. When the display screen needs to be assembled to the control handle 4, only the position of the display screen needs to be adjusted and the connecting members need to be buckled. Conversely, when the display screen needs to be disassembled, only the buckling state of the connecting members needs to be released.

[0441] In another optional embodiment, the band 4512 can also be an elastic rope which is elongated when pulled. The installation of the display screen to the control handle 4 is realized by the elastic force of the elastic rope.

[0442] In another optional embodiment, the display screen can also be matched to the control handle 4 by other tool-free disassembly manners. Those skilled in the art should be able to adapt various tool-free disassembly components without creative labor, which should all be included in the protection scope of the present embodiment.

[0443] In another optional embodiment, referring to FIG. 48 and FIG. 49, the active steering assembly is configured as a steering wheel component, the control handle 4 is a partial structure of the steering wheel which is convenient to hold, and the vehicle is turned according to the rotation amount of the steering wheel component controlled by the user. In the present embodiment, the display screen is configured to be tool-free disassembled at a position near the middle part of the steering wheel, so as to be convenient for observation and thumb control.

[0444] In another optional embodiment, after the display screen is disassembled from the vehicle, it can be carried to any position and the function setting of the display screen can be performed at any time. The set function is stored in the display screen, and when the vehicle needs to work, the display screen is reassembled to the vehicle, the garden vehicle reads the set function and works according to the pre-set function, solving the technical problem in the prior art that the setting can only be performed at the mower.

[0445] In one of the optional embodiments, the display screen can be used not only to display various state information of the vehicle, but also to control the function of the vehicle through the input mode configured on the display screen. The signal connection with the vehicle is not limited to wired connection, but also can be wireless connection through local area network such as Bluetooth or satellite communication. Therefore, the tool-free disassembly manner can make it more convenient for the user to control the vehicle.

[0446] In one of the optional embodiments, after the user disassembles the display screen, it is configured on the wrist of the user through a wrist strap or other connecting member, which can be used as a watch. At the same time, it is connected to the vehicle through wireless signal and can also control the function mechanism of the vehicle in real time.

[0447] In another optional embodiment, the user connects the detached display screen to an external electronic device, which can be a mobile phone, a tablet computer, a notebook computer, etc. The above-mentioned electronic device is connected to the vehicle through the display screen to realize operations such as vehicle maintenance, control, software upgrade, etc.

[0448] In another optional embodiment, the above-mentioned display screen that can be detached can be used as a portable smart device or a part of a smart device.

[0449] Specifically, in one of the optional embodiments, the display screen can be used as a smart watch, which is assembled to the active steering assembly through the watchband of the smart watch, and can be directly worn on the wrist of the user after being detached to be used as a smart watch.

[0450] Specifically, in another optional embodiment, the display screen is used as the watch dial of a smart watch, which is assembled to the active steering assembly through the above-mentioned clamping groove, clamping block or other clamping components in the prior art, and can be assembled to the watchband on the wrist of the user after being detached from the active steering assembly to be used as a smart watch.

[0451] Specifically, in another optional embodiment, the display screen is implemented as a handheld smart device such as a mobile phone, which is assembled to the active steering assembly of the vehicle to be used as a display screen when the user drives the multifunctional garden vehicle, and is detached to be used as a mobile phone for daily use when the user does not drive the vehicle.

[0452] Specifically, in one of the optional embodiments, the display screen is implemented as a handheld smart device such as a mobile phone, and the multifunctional garden vehicle connects the mobile phone through a support and uses the mobile phone as a display screen. In this embodiment, since the user has a personal mobile phone, the manufacturer of the vehicle does not need to equip the vehicle with a corresponding display screen, thereby reducing the production cost of the vehicle. Alternatively, the display screen is equipped with the vehicle, and the display screen is used as a mobile phone for the user when the vehicle is not driven. In addition, different display screens can be configured according to different needs of the user, such as different screen sizes, different screen materials, different SOC (system on chip) of the display screen, etc., thereby giving the user diversified choices for the vehicle.

[0453] In one of the optional embodiments, the multifunctional garden vehicle and / or the display screen include an authorization code for mutual pairing, which is used as the basis for pairing the multifunctional garden vehicle and the display screen. When the vehicle and the display screen are paired through the authorization code, the display screen can control the functional mechanism of the vehicle.

[0454] In another optional embodiment, the tool-free detachable display screen is configured with an authorization code that can be paired with the vehicle, and the display screen can only control the functions of the vehicle when and only when the pairing is completed, so as to avoid the interference of signals from other devices on the vehicle or the display screen, and to avoid the manipulation of the vehicle by irrelevant personnel through other devices from the outside.

[0480] Referring to FIG. 33, in an alternative embodiment, the functional mechanism includes a lighting lamp arranged on the front side or the rear side of the multifunctional garden vehicle, and correspondingly, one of the sub-controllers is a lighting lamp controller used to control the operation of the lighting lamp.

[0481] Referring to FIG. 1, in an alternative embodiment, the active steering assembly is arranged as a steering lever pivotally connected to the vehicle frame 1, and when the multifunctional garden vehicle is being controlled, the user controls the vehicle to move and steer by rotating the steering lever. In other embodiments, the active steering assembly can also be arranged as a steering wheel component, and in this case, the input unit is arranged on the steering wheel close to the user's hand holding position, and the vehicle steers according to the rotation amount of the steering wheel component controlled by the user.

[0482] In one of the alternative embodiments, referring to FIG. 1 and FIG. 33, the steering lever is arranged to be controllably rotated about a first axis 15 between a first forward position, a middle position and a first reverse position, and the first axis 15 is parallel to the left-right direction of the vehicle. The steering lever is provided with a deflection identifier arranged to identify the deflection position of the steering wheel, and the deflection identifier is connected to the walking controller.

[0483] When the steering lever is in the middle position, the walking controller controls the driving motor to not drive the driving wheel to rotate, and in this case, the vehicle is in a stationary state. When the steering lever is in the first forward position, the walking controller controls the real-time rotation speed of the driving motor to be equal to the maximum rotation speed of the current speed range.

[0484] In one of the alternative embodiments, referring to FIG. 2 and FIG. 33, the functional mechanism further includes a light strip 7 arranged on the surface of the steering lever and facing the front of the multifunctional garden vehicle; correspondingly, one of the sub-controllers is a light strip controller used to control the operation of the light strip 7.

[0485] The input unit in the embodiment is arranged on the active steering assembly, and the active steering assembly is operated by the user to drive the driving wheel, that is, the active steering assembly is closer to the user's hand, and it is more convenient for the user to operate the input unit. Since the input unit is close to the user's hand, the user's hand does not need to leave the active steering assembly during the process of inputting the to-be-verified information to the vehicle through the input unit, so the vehicle can be operated through the active steering assembly at any time, and the safety risk caused by leaving the active steering assembly is avoided.

[0486] Further, since the active steering assembly selects the steering rod or the steering wheel, both of which are located at the front of the vehicle, the user does not need to bend over or turn his head when looking at the input unit, and the visual range is not significantly different from the driving state of the whole vehicle, and even the user can observe the situation around the vehicle through the side light. Therefore, the situation around the vehicle can be observed in time, and the safety risk is further reduced.

[0487] As described above, with reference to FIG. 34, the unlocker in the embodiment further includes an unlocking detection unit. After the to-be-verified information input by the user through the input unit is verified by the unlocking detection unit, an unlocking signal is sent to the whole vehicle controller or the corresponding sub-controller of the controller system. The unlocking signal is used to trigger the controller system to set the multifunctional garden vehicle to an unlocked state. In the unlocked state, at least one functional mechanism can be activated.

[0488] In one of the optional embodiments, the unlocking detection unit and the input unit are arranged on the active steering assembly together. After the to-be-verified information is input by the user through the input unit, the information is sent to the unlocking detection unit. That is, the unlocking detection unit is directly connected with the input unit. In other optional embodiments, the unlocking detection unit is arranged at other positions of the vehicle, and does not affect the actual operation scheme of the unlocker. In other optional embodiments, the unlocking detection unit is not directly connected with the input unit. The signal of the input unit is sent to the unlocking detection unit through the controller system or other components after being transferred or preprocessed, but the unlocking detection unit is still responsible for the verification of the to-be-verified information, and does not affect the actual operation scheme of the unlocker.

[0489] The at least one functional mechanism that can be activated means that in one of the unlocked states, one or more functions can be activated.

[0490] In one of the optional unlocked states, the functional mechanism that can be activated only includes the walking assembly. In this state, the garden operation part of the multifunctional garden vehicle cannot be activated, that is, the garden operation part cannot effectively perform the garden operation, but the walking assembly can be controlled to drive the vehicle. When the multifunctional garden vehicle is in the scene of transfer, the garden operation part is in the state of being unable to be activated, and obviously, the safety is higher. Even if the user misoperates the control knob of the garden operation part, the garden operation part will not work, so that the safety performance of the vehicle is improved.

[0491] In one of the optional unlocking states, the activated function mechanism only includes the lighting lamp, and the garden operation part and the walking assembly of the multifunctional garden vehicle in this state cannot be activated, that is, the vehicle cannot drive and garden work, but the lighting lamp can be controlled to start to realize lighting. When the multifunctional garden vehicle is in a scene such as waiting for work arrangement in an environment with poor external lighting conditions, the multifunctional garden vehicle cannot drive and cannot start the garden operation part, that is, the most possible function of the multifunctional garden vehicle that causes a safety threat to the outside world is in a closed state, which is obviously more secure. Even if the user accidentally touches the walking assembly or the control of the garden operation part, the multifunctional garden vehicle will not drive and the garden operation part will not work, thereby improving the safety performance of the vehicle.

[0492] In one of the optional unlocking states, the activated function mechanism only includes the garden operation mechanism; the garden operation mechanism in this embodiment is the header 8, and the walking assembly and the lighting lamp of the multifunctional garden vehicle in this state cannot be activated, that is, the vehicle cannot drive and illuminate. When the multifunctional garden vehicle is in a state of repairing the header 8, the user needs to test the working condition of the header 8, and the state of the vehicle that cannot drive can ensure that the walking assembly of the vehicle does not run, even if the user accidentally touches the control of the driving assembly during the repair process, the garden vehicle will not drive and cause danger, thereby improving the safety performance of the vehicle.

[0493] In another optional unlocking state, the activated function mechanism includes the garden operation assembly and the lighting lamp; the garden operation mechanism in this embodiment is the header 8, and the walking assembly of the multifunctional garden vehicle in this state cannot be activated, that is, the vehicle cannot drive, but the lighting lamp can be started. When the multifunctional vehicle is repairing the header 8 in an environment with poor lighting, the lighting lamp can assist in lighting, thereby improving the lighting conditions of the environment and facilitating the user to repair the header 8.

[0494] In another optional unlocking state, the activated function mechanism only includes the lamp strip 7, that is, the lamp strip 7 of the vehicle can be started to display information to the outside world, but other function assemblies cannot be started. When the garden vehicle is in a fault state, the user should place the garden vehicle in this unlocking state, and the garden vehicle in this state only transmits warning or other information to the outside world through the lamp strip 7, but other function devices cannot be started to avoid aggravating the fault. The lamp strip 7 transmits warning information to the outside world, so that the user can more safely troubleshoot the vehicle.

[0495] In another optional embodiment, the multifunctional garden vehicle is in normal condition, and the vehicle can perform normal garden work. At this time, the garden vehicle is unlocked to enter a state in which all function mechanisms can be activated, and the user can drive the garden vehicle to start normal work.

[0496] In another optional embodiment, one or more function mechanisms of the multifunctional garden vehicle have slight faults, but the faults do not directly affect the work of the vehicle. For example, there is a difference in brightness between the left and right side lighting lamps, or the power display unit displays abnormally. The above slight faults do not directly affect the garden work, so in this embodiment, there is a corresponding unlocking state. In the unlocking state, the function mechanism with a slight fault is not activated, that is, all function mechanisms except the slight fault are activated to temporarily allow the user to continue work, and then the slight fault is repaired after the work is completed. The situation that the garden vehicle cannot work when it has a slight fault is avoided.

[0497] Further, in some embodiments, the multifunctional garden vehicle can activate one or more function mechanisms by setting different unlocking states. Various scenes can be better met.

[0498] In addition to the above application scenarios, the unlocking state in which at least one function mechanism is activated is also applied to temporarily open part of the authority to other users. Specifically, in one optional embodiment, when the vehicle is in a state of being handed over to external personnel, the external personnel is opened a to-be-verified information. When the to-be-verified information is verified by the unlocking detection unit, only the walking assembly of the garden vehicle is activated, and the external personnel can drive the garden vehicle to realize vehicle transfer, but cannot use the garden work parts and other function mechanisms.

[0499] Referring to FIG. 1 and FIG. 33, in one optional embodiment, the multifunctional garden vehicle is a mower, the walking assembly thereof includes a left drive wheel and a right drive wheel, and the work mechanism thereof includes a cutting deck 8 provided with a left cutter and a right cutter.

The lighting lamp controller is used to control the on-off, brightness, etc. of the lighting lamp. The light strip controller is used to control the on-off, brightness, display content, etc. of the light strip 7.

[0501] The multifunctional garden vehicle includes a power supply device, which includes a battery and a battery management system. As an example, the battery can be a lithium ion battery, a lead-acid battery, a nickel-hydrogen battery, or other types of power battery. The battery management system is used to manage the power supply of the multifunctional garden vehicle to each controller and functional mechanism.

[0502] The vehicle controller is communicatively connected to the walking controller, the cutter controller, the battery management system, etc. In some embodiments, the communication connection can be implemented as a controller area network bus (CAN) connection. The vehicle controller, the left walking controller, the right walking controller, the left cutter controller, the right cutter controller, the lighting lamp controller, and the light strip controller each have a unique address in the controller area network bus network, and they communicate messages according to their respective addresses.

[0503] The multifunctional working vehicle also includes a positive steering assembly configured as a steering lever. As an example, the steering lever includes a first steering lever 2 (left steering lever) and a second steering lever 3 (right steering lever). The left steering lever is configured with a left control handle 4, and the right steering lever is configured with a right control handle 4.

[0504] The left steering lever also includes a left deflection identifier for identifying the deflection angle of the left steering lever relative to the vehicle frame 1, and the right steering lever also includes a right deflection identifier for identifying the deflection angle of the right steering lever relative to the vehicle frame 1. The left deflection identifier is connected to the left walking controller for accepting user operation to output a control signal for the left drive wheel to the left walking controller. The right deflection identifier is connected to the right walking controller for accepting user operation to output a control signal for the right drive wheel to the right walking controller.

[0505] Thus, the left and right steering levers can be used to control the left and right drive wheels, so that the garden vehicle can move in a desired manner. Specifically, when the deflection identifier identifies that the steering lever is in the first forward position, the corresponding drive wheel moves forward at the maximum speed; when the deflection identifier identifies that the steering lever is in the middle position, the corresponding drive wheel does not rotate; and when the deflection identifier identifies that the steering lever is in the second reverse position, the corresponding drive wheel moves backward at the maximum speed. The maximum speed of the forward movement is not necessarily equal to the maximum speed of the backward movement.

[0506] Further, referring to FIG. 34, a functional block diagram of an unlocking scheme of the garden vehicle according to an embodiment of the present disclosure is shown. The garden vehicle comprises a controller system and an unlocker. The unlocker comprises an input unit and an unlock detection unit.

The display screen is used to prompt the user that the current state is the iris recognition state. In addition, the display screen can also display the unlocking state and other information.

[0530] In one of the specific optional embodiments, the input unit is configured as an image acquisition device arranged on the control handle 4 and capable of performing palm vein recognition. The user places the finger or palm on the recognition position of the image acquisition device, and effective recognition is performed, so that the required to-be-verified information is input to the input device.

[0531] Referring to FIG. 46, the input unit in this embodiment is configured as a fingerprint sensor. The data verification module is configured as a fingerprint verification module. The storage module is used to store the preset to-be-verified fingerprints and the correspondence between the to-be-verified fingerprints and the unlocking states. The data management module is configured as a fingerprint management module for managing the preset to-be-verified fingerprints in the storage module, such as adding, deleting, and managing the correspondence between each preset to-be-verified fingerprint and the unlocking state.

[0532] In one of the specific optional embodiments, the input unit is configured as an image acquisition device arranged on the control handle 4. The user can show other preset pictures or characters to the image acquisition device, so as to input the required to-be-verified information to the input device. The preset pictures or characters include two-dimensional code information and the like. When the user temporarily authorizes a person to have an unlocking state, the temporary authorization can be realized by providing the corresponding two-dimensional code information.

[0533] In one of the specific optional embodiments, the input unit is configured as a two-dimensional code recognition unit arranged on the control handle 4. The two-dimensional code recognition unit can recognize two-dimensional codes, bar codes, and other graphics that store information through specific coding methods. The user can show the two-dimensional codes, bar codes, and other graphics to the image acquisition device, so as to input the required to-be-verified information to the input device.

[0534] In another optional embodiment, referring to FIG. 41, the input unit is configured as a voice acquisition device arranged on the control handle 4. The voice acquisition device can acquire the voiceprint or other preset voice information of the user. The dotted circle with the control handle 4 as the center in the figure represents the effective recognition range of the voice acquisition device. As shown in the figure, when the user is riding the garden vehicle, the head of the user should fall within the effective recognition range, so as to input the voice information to the input unit.

[0535] Referring to FIG. 47, the input unit in this embodiment is configured as a voiceprint sensor. The data verification module is configured as a voiceprint verification module, the storage module is used to store preset voiceprints to be verified, and the correspondence between the voiceprints to be verified and the unlocking states. The data management module is configured as a voiceprint management module for managing the preset voiceprints to be verified in the storage module, such as adding, deleting, and corresponding relationship between each preset voiceprint to be verified and the unlocking state.

[0536] Further, it should be understood that the voice information collected by the voice collection device can not only be processed to obtain voiceprint information, but also be processed to obtain sentence information, which can contain instructions for enabling the garden vehicle to enter a specified unlocking state, for controlling the garden vehicle to enter the unlocking state desired by the user.

[0537] In another optional embodiment, the input unit is configured as a fingerprint collection device arranged on the control handle 4, which can collect the fingerprint of the user to realize input of the to-be-verified information to the input unit.

[0538] In another optional embodiment, the input unit is configured as a palmprint collection device arranged on the control handle 4, which can collect the fingerprint of the user to realize input of the to-be-verified information to the input unit. Further, the palmprint collection device for identifying the palmprint of the user can be arranged on the gripping portion of the control handle 4 for the user to hold. When the user holds the gripping portion, the palmprint collection device can directly obtain the palmprint information.

[0539] Referring to FIG. 1, the garden vehicle in this embodiment includes a seat 5 for the user to sit on, which is arranged on the vehicle frame 1. The input unit is arranged on the control handle 4, and the input unit is inclined upward and points to the upper side of the seat 5 when the steering rod is located at the intermediate position. Further, since the control handle 4 is closer to the face of the user when sitting on the seat 5, the head of the user does not need to be additionally moved or twisted when the face information of the user has been collected and the unlocking state information has been displayed to the user through the display screen on the handle. In addition, when the hand of the user needs to be involved in unlocking, the feature that it is closer to the front of the user is also more convenient for the user to operate.

[0540] Further, the steering rod includes a gripping portion for the user to hold, and the input unit is arranged on the side where the thumb is located when the user holds the corresponding gripping portion. That is, when the user normally controls the garden vehicle, the hand of the user should be kept in the state of holding the control handle 4. In this state, the thumb easily operates the input unit, and the operation is more convenient. After unlocking, the user can directly control the vehicle through the handle without moving the hand. The risk situation caused by the hand not holding the control handle 4 during unlocking can be effectively avoided.

[0541] In some embodiments, the input unit uses the above-mentioned biometric information as the to-be-verified information. In the technical solution in which the user's face, iris, and voiceprint information is collected as the to-be-verified information, the hand can be kept in a normal operating state, and there is no difference from normal driving, thereby having high safety performance.

[0542] In some embodiments, the input unit uses the information of the finger / palm print, finger / palm vein, and the like of the hand as the to-be-verified information, and the user almost does not need to look at the input unit and can keep observing the surroundings of the vehicle, which is the same as normal driving and has high safety performance.

[0543] In some embodiments, the user inputs a password, fingerprint, or finger vein of the thumb as the to-be-verified information. In this process, the user always holds the control handle, and the steering component is mainly controlled by the palm holding the control handle. Therefore, the action of moving the thumb to input the to-be-verified information does not affect the safety performance of driving, and the safety performance of driving is relatively improved.

[0544] The control handle 4 is located on the side of the steering rod away from the vehicle. Referring to FIG. 1 and FIG. 37, the input unit is arranged on the control handle 4, and the input unit is inclined toward the upper rear of the vehicle. Specifically, when the input unit is located at the middle position of the steering rod, the input unit is inclined toward the upper rear of the vehicle, and the angle between the input unit and the horizontal plane is 30°-60°. Referring to FIG. 42, the straight line b is located on the horizontal plane of the input unit, the straight line d is the vertical line of the input unit, the dashed line a is the direction of the input unit, and the angle α is the angle between the dashed line a and the straight line b, that is, the above-mentioned angle is 30°-60°.

[0545] When a normal adult sits on the seat 5, the eyes are within the above-mentioned angle range, so that the input unit can better collect the face information of the user. In addition, the control handle 4 rotates with the steering rod around the first axis 15 in the front-rear direction. In the above-mentioned angle range, the display screen of the control handle 4 is in a state that is easily observed by the user in each position.

[0546] Further, in an optional embodiment, the angle α between the direction of the input unit and the horizontal plane is 40°-50° when the steering rod is located at the middle position. It is calculated that the eyes of most users of the garden vehicle are located within the above-mentioned angle range of the input unit when the users sit on the seat 5. A small number of users with a large height difference can adjust their eyes to the above-mentioned position by the seat lifting device, so as to obtain a better use experience.

[0547] In the above-mentioned position relationship, the input unit of the vehicle can better adapt to almost all users of different sizes and meet the needs of almost all users of different sizes to quickly input the to-be-verified information to the input unit.

[0548] In one of the optional embodiments, a display screen is arranged at the control handle 4. In addition to the input unit, the display screen can also display other information to the user, such as indicating that the garden vehicle is currently in an unlocked state or a certain unlocked state, or reminding the user that the current password input is incorrect, or other vehicle status information such as battery power.

[0549] In one of the optional embodiments, referring to FIG. 42, the multifunctional garden vehicle includes a seat 5 for carrying a user, and the seat 5 includes a seat cushion and a seat back. The vertical line e in the figure is the vertical line of the seat back, and the horizontal line c is the horizontal line of the seat cushion.

[0550] The distance between the input unit and the seat back in the front-rear direction of the vehicle is 400mm-800mm, i.e., the distance between the straight line d and the straight line e in FIG. 42 is 400mm-800mm; and the distance between the input unit and the seat cushion in the up-down direction is 300mm-700mm, i.e., the distance between the straight line b and the straight line c in FIG. 42 is 300mm-700mm. Under the above positional relationship, the user sitting on the seat 5 can input various to-be-verified information to the input unit relatively more comfortably.

[0551] In one of the optional embodiments, the steering rod includes a left steering rod and a right steering rod respectively controlled by two hands of the user, and the left steering rod and the right steering rod are respectively used to control the rotation of the corresponding side drive wheel; the left steering rod and the right steering rod are both arranged with an input unit, and when the input units of the left steering rod and the right steering rod are both input with to-be-verified information that can be verified by the unlocking detection unit, at least one of the function assemblies can be activated and drive the drive wheel to rotate.

[0552] Specifically, when the input units of the left steering rod and the right steering rod are both input with to-be-verified information that can be verified by the unlocking detection unit, the walking assembly is in an activated state. In other words, when only one of the steering rods is input with to-be-verified information that can be verified by the unlocking detection unit, the garden vehicle cannot enter the unlocked state in which the walking assembly can be activated. Thus, the user is identified: only when both hands of the user can control the steering rod, the vehicle can start and run, avoiding the safety risk caused by single-handed operation of the user. That is, the use safety of the product is improved.

[0553] In another optional embodiment, referring to FIG. 43, the input unit can also include a wireless connection to a wireless receiver for enabling the user to traverse various terrains and perform work. In this embodiment, when the user is away from the vehicle and needs to temporarily authorize personnel near the vehicle, the user can send the to-be-verified information to the cloud through a mobile phone, computer, or other device, and the to-be-verified information is sent to the input unit by the cloud, so that the vehicle enters the corresponding unlocked state, thereby realizing temporary authorization of personnel near the vehicle. This scenario applies when the owner of the garden vehicle is away from home and needs to control or unlock the garden vehicle due to special circumstances.

[0554] In another optional embodiment, referring to FIG. 34, the unlocking detection unit of this embodiment is not directly coupled to the controller system, but is directly coupled to the battery management system for directly managing the power supply of the functional mechanism. For example, in the unlocked state where only the walking assembly can be activated, the battery management system disconnects the power supply of the garden working components and other functional mechanisms.

[0555] Further, in another optional embodiment, the battery management system can also serve as a port for transmitting signals. The signal of the unlocking detection unit is sent to the vehicle controller in the controller system through the battery management system, and the vehicle controller generates a control signal to the sub-controller. All of the above should be included in the protection scope of the present application.

[0556] In another optional embodiment, the garden vehicle is provided with the above-mentioned display screen. When the garden vehicle is not in any of the unlocked states and is controlled, the display screen displays the interface shown in FIG. 64, which displays a lock floating window 446 to inform the user that the current state is locked and the vehicle cannot be controlled until it is unlocked.

[0557] In another optional embodiment, when the garden vehicle is in one of the unlocked states, the user's control cannot activate the functional assembly at this time. The display screen displays the interface shown in FIG. 64, which displays a lock floating window 446 to inform the user that the current control of the functional mechanism is in a locked state, and the corresponding functional mechanism cannot be controlled until it is unlocked.

[0558] In another optional embodiment, when the garden vehicle is not in any of the unlocked states, the input unit of the unlocking device is always in a working state, i.e., the user can input to-be-verified information to the input unit at any time without additional operation, which can make the garden vehicle enter the corresponding unlocked state, thereby quickly starting and using the garden vehicle, especially through the unlocking mode of finger / palm print, password, etc.

[0559] In another optional embodiment, when the garden vehicle is not in any of the unlocking states, the input unit of the unlocker is in a default silent state and does not actively collect information, so as to avoid collecting the private information of the user, especially the image acquisition device, the voiceprint sensor and the like as the unlocking mode of the input unit; the garden vehicle of these embodiments is provided with a switch for energizing the unlocker, and the power supply system 6 supplies power to the unlocker when the switch is triggered, at which time the input unit starts to work, and the user can input the to-be-verified information to the input unit. In this implementation, the user information is not collected at any time, thereby effectively protecting the privacy of the user.

[0560] In another optional embodiment, referring to FIG. 48, FIG. 49 and FIG. 50, the active steering assembly of the garden vehicle is configured as a steering wheel structure, the steering wheel includes a control handle 4 held by the user and having a ring structure, and the control handle 4 is provided with a control member for controlling at least one functional mechanism to generate a functional state change, and when the user normally holds the control handle 4 of the steering wheel, the control member is close to the thumb of the user.

The functional mechanism can be any one or more of the garden work components, walking assemblies, display areas, and other components in the above-mentioned embodiments.

[0580] The garden vehicle of the present embodiment also comprises a display screen, which is configured as a touch screen 44 that can be controlled by human touch. The touch screen 4 displays a first interface 441 after being powered on, and the first interface 441 has a plurality of first function selection areas.

[0581] In one of the optional embodiments, the controller system stores therein function configuration parameters corresponding to the first function selection area, and the controller system controls the function mechanism to generate a function state change according to the corresponding function configuration parameters when the first function selection area is operated by the user.

[0582] In one of the optional embodiments, the touch screen 44 displays a second interface when one of the first function selection areas is operated by the first operation; the second interface includes a function configuration area, and the controller system stores therein function configuration parameters corresponding to the function configuration area, and the controller system controls the function mechanism to generate a function state change according to the corresponding function configuration parameters when the parameter configuration area is operated by the user.

[0583] In one of the optional embodiments, the touch screen 44 displays a floating window on the second interface when the parameter configuration area is operated by the first operation; the floating window includes a to-be-selected configuration parameter; the first operation is a point-press operation; in response to the to-be-selected configuration parameter being operated by the first operation, the parameter configuration area of the second interface is changed to the to-be-selected configuration parameter operated by the first operation; the controller system stores therein function configuration parameters corresponding to the to-be-selected configuration parameter, and the controller system controls the function mechanism to generate a function state change according to the corresponding function configuration parameters when the parameter configuration area of the second interface is changed to the to-be-selected configuration parameter operated by the first operation.

[0584] In one of the optional embodiments, the touch screen 44 enters a third interface when the parameter configuration area is operated by the first operation; the third interface includes a plurality of to-be-selected configuration parameters; the first operation is a point-press operation; the touch screen 44 enters the second interface when one of the to-be-selected configuration parameters is operated by the first operation, and the parameter configuration area of the second interface is changed to the to-be-selected configuration parameter operated by the first operation.

[0585] In one of the optional embodiments, referring to FIG. 53, the first interface 441 shown in the figure includes a plurality of first function selection areas: a date function area 44101, a Bluetooth function area 44102, a light function area 44103, a parking function area 44104, a straight-line calibration function area 44105, a cutter function area 44106, a fast travel function area 44107, a travel speed setting area, and a slow travel function area 44109, which are respectively used to generate different control effects under the control of the user.

[0586] Specifically, in one of the optional embodiments, one of the first function selection areas is the cutter function area 44106, and referring to FIG. 54, FIG. 55, and FIG. 56, the second interface entered by the cutter function area 44106 when operated by the first operation is a cutter configuration interface 442, and the cutter configuration interface 442 includes a cutter function configuration parameter area that can be used to generate a function state change of the cutter.

[0587] In one of the optional embodiments, referring to FIG. 54, the cutter parameter configuration area includes a target rotating speed selection area, the target rotating speed selection area includes a plurality of candidate target rotating speeds, and the rotating speed of the cutter is configured to the target rotating speed selected by the user in response to the first operation of the user.

[0588] In one of the optional embodiments, the target rotating speed selection area includes at least two of high, medium, low, and adaptive target rotating speeds.

[0589] Specifically, in one of the optional embodiments, the target rotating speed selection area includes three candidate target rotating speeds, i.e., high, medium, and low target rotating speeds, respectively; if the high target rotating speed is selected by the user in response to the first operation of the user, the cutter is configured to the high target rotating speed; if the medium target rotating speed is selected by the user in response to the first operation of the user, the cutter is configured to the medium target rotating speed; and if the low target rotating speed is selected by the user in response to the first operation of the user, the cutter is configured to the low target rotating speed. More specifically, the controller system is configured with cutter configuration parameters corresponding to each candidate target rotating speed, and when one of the target rotating speeds is selected by the user in response to the first operation of the user, the controller system controls the cutter to operate with the corresponding cutter configuration parameters, thereby enabling the cutter to enter the corresponding target rotating speed state.

[0590] In another optional embodiment, referring to FIG. 54, the target rotating speed selection area of the cutter configuration interface 442 further includes an adaptive rotating speed, i.e., “AUTO” shown in the figure, and in response to the adaptive rotating speed being selected by the user in response to the first operation of the user, the garden vehicle enters a cutter rotating speed adaptive state, and the real-time rotating speed of the cutter changes with the density of the grass at the working position: when the grass is dense, the rotating speed of the cutter increases; and when the grass is sparse, the rotating speed of the cutter decreases.

[0591] Specifically, when the vehicle is in the cutter rotating speed adaptive state, if the controller system determines that the current grass becomes denser, the rotating speed of the cutter is controlled to increase; otherwise, if the controller system determines that the current grass becomes sparser, the rotating speed of the cutter is controlled to decrease. When the garden vehicle of the present embodiment works in an area where the density of the grass varies to a certain extent, the garden vehicle enters the cutter rotating speed adaptive state through the cutter configuration interface 442. In this state, the rotating speed of the cutter changes with the density of the grass, which not only avoids the situation that the grass cannot be effectively cut when the grass becomes denser, but also avoids the situation that the rotating speed of the cutter is relatively fast when the grass is sparse, thereby causing energy waste. That is, the garden vehicle in this state can effectively balance the cutting effect and energy saving.

[0592] In one of the optional embodiments, referring to FIG. 54, the cutter parameter configuration area includes a rotating direction selection area, the rotating direction selection area includes a rotating direction consistent area and a rotating direction inconsistent area.

[0593] In one of the optional embodiments, in response to the rotation-consistent area being operated by the user, each of the cutting knives of the cutting table 8 rotates in the same direction. Further, the rotation-consistent area includes a rotation-consistent switching area, and the user can realize the adjustment of the rotation direction of the cutting knives by operating the rotation-consistent switching area. That is, the rotation direction of each of the cutting knives is changed simultaneously, for example, each of the cutting knives is configured to rotate clockwise (forward direction) or counterclockwise (reverse direction).

[0594] In response to the rotation-inconsistent area being operated by the user, each of the cutting knives of the cutting table 8 does not rotate in the same direction. Further, the rotation-inconsistent area includes a rotation-inconsistent switching area, and the user can realize the adjustment of the rotation direction of the cutting knives by operating the rotation-inconsistent switching area. That is, the rotation direction of each of the cutting knives is changed respectively, for example, two of the cutting knives are configured to rotate clockwise (forward direction) and counterclockwise (reverse direction) respectively, or two of the cutting knives are configured to rotate counterclockwise (reverse direction) and clockwise (forward direction) respectively.

[0595] Referring to FIG. 54, a schematic diagram of the cutting knife configuration interface 442 configured with two cutting knives is shown. In this embodiment, the rotation-consistent area is “double-knife consistent” shown in the diagram, and the rotation-inconsistent area is “double-knife inconsistent” shown in the diagram. In addition, in other embodiments, the garden vehicle can also be configured with three or more cutting knives, and the cutting knife configuration interface 442 can be adjusted accordingly.

[0596] Referring to FIG. 57, a schematic diagram of the cutting knife configuration interface 442 in one state is shown. In this embodiment, the cutting knife configuration interface 442 includes a one-way selection area in which the rotation-consistent area is operated by the user and a one-way floating window 4422 is displayed. The one-way floating window 4422 is overlaid on the cutting knife configuration interface 442, and the one-way floating window 4422 includes a forward direction selection area and a reverse direction selection area. That is, the one-way floating window is displayed when the “double-knife consistent” area shown in the diagram is operated by the user (the shaded state of the “double-knife consistent” area in the diagram indicates that it is selected by the user), or the one-way floating window is displayed when the “forward direction” area shown in FIG. 55 is operated by the user.

[0597] When the rotation-consistent area is operated by the user, the forward direction selection area and the reverse direction selection area of the one-way floating window 4422 can be operated by the user. In response to the forward direction selection area being operated by the user, each of the cutting knives of the cutting table 8 rotates in the forward direction. In response to the reverse direction selection area being operated by the user, each of the cutting knives of the cutting table 8 rotates in the reverse direction.

[0598] In one of the optional embodiments, the cutter configuration interface 442 comprises a bidirectional selection area where the user's first operation is inconsistent with the display of a bidirectional floating window, the bidirectional floating window is overlaid on the cutter configuration interface 442, and the bidirectional floating window comprises a first turning selection area and a second turning selection area; the first turning area and the second turning area correspond to different turning configurations of each cutter, respectively; in response to the first turning area or the second turning area being operated by the user, each cutter of the cutter table 8 rotates in the corresponding turning direction.

[0599] Specifically, in one of the optional embodiments, the garden vehicle is configured with two cutters, and the bidirectional floating window comprises two options: the first turning selection area is an option for controlling the two cutters to rotate in the forward and reverse directions, respectively; and the second turning selection area is an option for controlling the two cutters to rotate in the reverse and forward directions, respectively.

The user platform is used to carry the operator of the multi-functional vehicle, and can include at least one of a seat or a standing platform. In FIG. 1, the user platform is configured as a seat 5 by way of example. The seat 5 or the standing platform is used for the operator to sit or stand. That is, the multi-functional vehicle can provide a riding working mode or a standing working mode. Further, the structure of the seat and the standing platform can be switched flexibly, that is, the working mode of the multi-functional vehicle can be switched flexibly between the riding working mode and the standing working mode according to the actual needs of the operator.

[0662] Referring to FIG. 66, a mower disclosed in the present specification includes a vehicle frame 1, a cutting deck 8 arranged on the lower side of the vehicle frame 1, a power mechanism, a power supply system 6, and a control handle 4. The power supply system 6 includes a battery pack.

[0663] The cutting deck is connected to the vehicle frame 1, and includes a cutting knife that rotates to cut grass. The power mechanism is connected to the vehicle frame 1, and is drivingly connected to the first driving wheel and the second driving wheel. The battery pack is connected to the vehicle frame 1, and is used to supply power to the cutting deck and the power mechanism.

[0664] Referring to FIG. 66, the mower is provided with a first steering rod 2 and a second steering rod 3 on the left and right sides thereof, respectively. The first steering rod 2 is operatively coupled to the first driving wheel of the mower, and is used to rotate the first driving wheel. The second steering rod 3 is operatively coupled to the second driving wheel of the mower, and is used to rotate the second driving wheel.

[0665] The power mechanism of the present embodiment includes a first power mechanism connected to the first driving wheel and a second power mechanism connected to the second driving wheel. Therefore, the control mode of the driving wheels is as follows: when the operator needs to start rotating the first driving wheel or adjust the rotating speed of the first driving wheel, the operator should send a corresponding signal to the power mechanism through the first control handle. When the operator needs to start rotating the second driving wheel or adjust the rotating speed of the second driving wheel, the operator should send a corresponding signal to the power mechanism through the second control handle.

[0666] Referring to FIG. 67 and FIG. 68, the first steering rod 2 and the second steering rod 3 each include a control handle 4 for a user to hold, the control handle 4 has a non-circular cross-sectional outer profile when viewed in an axial direction thereof, and the cross-sectional outer profile is composed of arc lines and straight lines connected head to tail to form a closed shape; the arc lines and straight lines of the cross-sectional outer profile correspond to curved surface regions and planar regions of an outer wall of the handle, respectively; from an anatomical perspective, the metacarpal bones of a human hand are significantly longer than the proximal phalanges and the distal phalanges, and this structure enables the palm to stably grasp under the action of muscles, but the relatively long metacarpal bones make it impossible for the hand to fully conform when grasping a cylindrical structure, which can cause local stress to be relatively concentrated, and for a person who maintains this holding posture for a long time, hand fatigue is quite likely to occur.

[0667] The length of the cross section in a first direction (the direction of the horizontal dashed line in FIG. 67) is f, and the length of the cross section in a second direction (the direction of the vertical dashed line in FIG. 67) that is different from the first direction is g, and 3≥f / g>1. In this embodiment, the first direction is perpendicular to the second direction. That is, the length of the cross section of the control handle 4 in one direction is greater than the length in the other direction, and when a user normally holds the control handle 4, referring to FIG. 69, the palm extends in the first direction; the fingers other than the thumb bend and are locally parallel to the second direction, at which time the fingers and the palm together wrap around the control handle 4 to achieve holding of the control handle 4. Based on the above size conditions of the control handle 4, the hand of the user can produce better conformance when holding the handle, and the action of the user holding the handle is closer to the natural relaxed state of the palm, so the user can hold the control handle 4 more comfortably, and the comfort of the user is improved.

[0668] Further, referring again to FIG. 67 and FIG. 68, the cross-sectional outer profile is composed of two semicircles and two straight line segments, the diameter of the semicircles is g, and the sum of the diameter of the semicircles and the length of one straight line segment is f. In this embodiment, f=40 mm and g=32 mm. In other embodiments, f=36 mm and g=27 mm, or f=45 mm and g=36 mm can be selected. As can be seen from the drawings, the cross-sectional outer profile of the control handle 4 is a waist-shaped structure with two semicircles on the sides and a flat middle portion. It is particularly noted that the sizes of the palms of different users differ, but the sizes of the palms of users in a similar geographic location are generally the same, so the average palm size of users in a region should be targeted for adaptation, and for regions with an average larger palm, the values of f and g should be larger, and vice versa, but overall the condition 3≥f / g>1 should be met, which can effectively improve the holding comfort of the user.

[0669] Referring to FIG. 69, a state diagram of a user's hand holding the control handle 4 is shown. As previously described, in this state, the palm of the user's hand is positioned against the aforementioned planar region 404, and the fingers are bent to wrap around the curved region 405. The palm of the human hand corresponds to the metacarpal, and in the extension direction of the palm, bending cannot occur, i.e., the palm is relatively flat. The flat palm abutting against the planar region 404 can make the hand and the handle fit more closely, and the relative position of the hand and the handle is less in the air, and the comfort of holding is correspondingly higher, effectively relieving hand fatigue caused by long-time holding of the handle.

[0670] Referring to FIG. 70, another state diagram of a user's hand holding the control handle 4 is shown. As can be seen from the diagram, the proximal phalanx of the user's hand is positioned against the aforementioned planar region 404, and the middle phalanx, the distal phalanx, and the metacarpal are wrapped around the curved region 405 before and after the planar region 404. The proximal phalanx is the part of the human finger closest to the metacarpal, and its length is greater than that of the middle phalanx and the distal phalanx. The proximal phalanx of the hand is also relatively flat. The flat proximal phalanx abutting against the planar region 404 can also make the hand and the handle fit more closely. The middle phalanx and the metacarpal are bent on both sides of the proximal phalanx and abut against the handle, so that the relative position of the hand and the handle is less in the air, and the comfort of holding is correspondingly higher.

[0671] It should be noted that FIG. 69 and FIG. 70 correspond to the hand holding the handle in different postures, and the two holding postures also correspond to the common holding habits of most users. In the two postures, the hand is fitted to the planar region 404 by the metacarpal and the proximal phalanx, respectively.
