Description

[Technical Field]

[0001] This utility model relates to the field of vehicle engineering technology, and in particular to a multi-functional garden vehicle and a ride-on lawnmower. [Background Technology]

[0002] Garden vehicles generally refer to vehicles used for outdoor gardening operations, mainly including vehicles used for garden cutting and maintenance.

[0003] Take lawnmowers as an example: lawnmowers are one of the fastest-growing garden vehicles in recent years. They are equipped with a cutting platform for cutting and maintaining grass, as well as other functional mechanisms. A significant portion of lawnmowers are controlled by a steering lever, which inevitably needs to be wired to the controller located on the vehicle body via a signal line.

[0004] Since the steering rod transmits the user's driving intentions to the vehicle through its rotation, the steering rod needs to be rotatably connected to the vehicle body. Under this connection method, the signal cable needs to have a length margin at the hinge point between the steering rod and the vehicle body to avoid interference with the vehicle body. However, tests have shown that the length margin of the signal cable in the existing technology is too long. The vibration generated during the operation of the lawnmower will cause the length margin to shake and rub against the vehicle body. After long-term operation, the signal cable will wear out severely or even lose communication.

[0005] All existing garden vehicles suffer from the aforementioned technical problems. Therefore, it is of great importance to propose a multi-functional work vehicle that can solve these problems. [Utility Model Content]

They do not indicate or imply that the device referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0078] Unless otherwise specified, the terms "set", "connected" and "connected" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0079] Compared to traditional fuel-powered garden vehicles, electric garden vehicles offer advantages such as all-weather zero emissions, zero fuel consumption, low noise, and simple maintenance (no gasoline, no engine oil, no air filter, no spark plugs, no fuel storage, etc.). The power system of electric garden vehicles uses electric motors instead of fuel engines, and the electric motors of the drive wheels can be controlled separately to achieve motion control of the whole vehicle, such as straight driving, reversing, turning, and zero steering. This reduces the structural complexity of the whole vehicle and makes the control of the whole vehicle more flexible.

[0080] Rechargeable garden vehicles are complex systems composed of multiple functional components that perform various functions. The most critical component is the combination of various electric motors and other functional parts. Rechargeable garden vehicles require safe, precise, and stable control for each functional component to ensure the vehicle operates efficiently and reliably.

[0081] It is understood that in some alternative embodiments, the cutting platform can be replaced with other components, such as sweeping, snow sweeping, snow shoveling, flushing, bucket, or components for grabbing and transporting goods, thus adapting the lawnmower to corresponding work vehicles, such as sweepers, snow sweepers, snow shovels, flushing machines, loaders, and transport vehicles. Those skilled in the art should be able to adapt various functional components without inventive effort, and all of the above should be included within the scope of protection of this embodiment.

[0082] This embodiment discloses a multifunctional garden vehicle, including a frame 1, functional mechanisms, a power system 6, a controller system, a steering rod, etc.

[0083] The functional components include garden operation parts, walking components, and other parts configured on the frame 1 and used to perform specific functions of the multi-functional garden vehicle; specifically, the garden operation parts are used to perform garden operations, and the walking components are driven to the drive wheels on both sides of the frame 1 to drive the multi-functional garden vehicle to move and steer.

[0084] A power supply system 6 is mounted on the frame 1 and supplies power to functional mechanisms, etc. A vehicle control system is mounted on the frame 1 and controls at least one functional mechanism to produce changes in its functional state. The steering lever rotates in a controlled manner about a first axis 15, which is parallel to the left-right direction of the vehicle; the direction of rotation of the steering lever about the first axis 15 is referenced in the attached diagram. Figure 3 The direction indicated by the curved line with an arrow.

[0085] Furthermore, the power system 6 is detachably connected to the vehicle frame 1. The power system 6 includes multiple battery units. These multiple battery units can be at least one of a first-specification battery pack or a second-specification battery pack. The differences in specifications between the first-specification battery pack and the second-specification battery pack include, but are not limited to, differences in battery pack capacity, voltage, internal resistance, weight, size, energy density, cell type, charge information, and battery health status information.

[0086] In some alternative embodiments, the difference between the first-specification battery pack and the second-specification battery pack lies in their battery pack capacities. The first-specification battery pack has a larger capacity than the second-specification battery pack. The second-specification battery pack is configured to power handheld garden tools. For example, the second-specification battery pack can power garden tools such as lawnmowers, pruning machines, hair dryers, and chainsaws. Furthermore, the second-specification battery pack can also power torque-output tools such as electric drills and hammer drills; sawing tools such as circular saws, jigsaws, and reciprocating saws; or grinding tools such as angle grinders and sanders.

[0087] In some alternative embodiments, the difference between the first-specification battery pack and the second-specification battery pack lies in the type of battery cells used. For example, the first-specification battery pack and the second-specification battery pack can respectively use lithium iron phosphate cells and ternary lithium cells. The multiple battery units in the power system 6 can also be nickel-cadmium battery cells, lead-acid battery cells, graphene cells, etc.

[0088] The power system 6 uses at least one of the first-specification battery pack and the second-specification battery pack. This allows the multi-functional vehicle to be compatible with different specifications of battery packs, meeting the needs of high-power operation while also being compatible with handheld electric garden tools, making the work of garden workers more flexible.

[0089] In one alternative embodiment, the power system 6 further includes a battery compartment, a battery management system, etc., wherein the battery compartment is used to house the battery pack and the battery management system is used to manage the power supply of the battery to various components of the vehicle.

[0090] In one alternative embodiment, the battery compartment and / or battery management system are configured on the vehicle frame, and the battery pack is detachably configured in the battery compartment to enable the battery pack to be removed and replaced, and the removed battery pack can be used for the other electric garden tools mentioned above.

[0091] In one alternative embodiment, the battery compartment is detachably mounted on the vehicle frame, and the battery is housed within the battery compartment, meaning the battery compartment can be completely separated from or attached to the vehicle frame.

[0092] In one specific alternative embodiment, the vehicle frame is equipped with a power supply interface, the battery compartment is attached to the vehicle and electrically connected to the power supply interface, and the entire battery compartment is detachable, allowing the user to replace the entire battery pack in the fastest possible time. In other words, when it is necessary to replenish the vehicle's power by replacing the battery pack, replacing the entire battery compartment is more efficient.

[0093] In this embodiment, at least two functional mechanisms are configured. These mechanisms include garden operation components and a walking assembly, which enable the multi-functional garden vehicle to change its functional state. The garden operation components are used for garden maintenance work, and the walking assembly is driven by the drive wheels on both sides of the frame 1 to propel the multi-functional garden vehicle. Both the garden operation components and the walking assembly have at least two switchable functional states. Specifically, the functional states of the garden operation components include different garden operation power or garden operation actions. Furthermore, the garden operation components have an adjustable-speed operating motor, with different speeds in different functional states. The functional states of the walking assembly include different walking speeds and walking directions. Switching between these different functional states constitutes the aforementioned functional state change. The walking assembly has an adjustable-speed walking motor, with different speeds in different functional states.

[0094] The aforementioned multi-functional garden vehicle also includes an active steering component, which is operatively coupled to the vehicle's running gear to create a speed difference between the left and right drive wheels, thereby causing the vehicle to rotate. In other words, the active steering component can actively create a speed difference between the left and right drive wheels when manually controlled, rather than requiring external force to steer the vehicle and then creating a speed difference in the drive wheels.

[0095] The aforementioned garden vehicles also include a controller system that can control functional mechanisms and generate changes in functional states.

[0096] Please see Figure 1 The active steering component in this embodiment also includes a control handle 4 for the user to hold and operate. The control handle 4 is equipped with a control board and at least two control elements coupled to the control board. A single control element can be used to control one of the functional mechanisms and cause it to produce a functional state change. The signals generated by the operation of at least two control elements are transmitted to the controller system, so that the controller system controls the functional mechanism to produce a functional state change.

[0097] Please see Figure 1 In this embodiment, the gardening operation component is a cutter 8 connected to the frame 1. The cutter 8 includes a rotating blade that produces a mowing effect on the grass. In other embodiments, the gardening operation component may also be a component with gardening operation functions such as snow sweeping, snow blowing, snow shoveling, flushing, and bucketing, or a component that can assist in construction during gardening operations, such as grabbing and transporting goods. Those skilled in the art should be able to adapt the operation component in this embodiment to various functional components without creative effort, and all of the above should be included within the protection scope of this embodiment.

[0098] As described above, when the gardening operation component is the mower 8, the multi-functional garden vehicle is a lawnmower, and the operating motor in the mower is configured as a mowing motor. Furthermore, if the gardening operation component is a snow sweeping component, then the multi-functional garden vehicle is a snow sweeper. That is, the gardening operation component, as the main functional component of the multi-functional garden vehicle, can be changed according to the user's selection. Simultaneously, in some embodiments, the aforementioned gardening operation component can also be a component that the user can replace according to actual needs. For example, removing the mower 8 used for mowing and replacing it with a sweeping disc used for sweeping would change the lawnmower into a sweeper. In summary, replacing the gardening operation component with any functional component according to user needs should not be construed as exceeding the protection scope of this embodiment.

[0099] The cutting platform 8 in this embodiment includes a mowing motor for driving the cutter blade to rotate. The required speed of the cutter blade varies depending on different working conditions and mowing needs. Therefore, the mowing motor is configured with multiple target speeds. The user controls the control unit to send a control signal to the control board to configure the speed of the mowing motor to one of the target speeds. For example, when the grass to be cut is dense or the user wants to complete the effective cut in a shorter time, the cutting platform 8 can be adjusted by increasing the cutter blade speed. Specifically, this involves increasing the target speed of the mowing motor. In this case, the control unit of the mowing motor adjusts the motor's duty cycle, causing the speed of the mowing motor to increase and approach the target speed until the actual speed of the mowing motor equals the target 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 rather wants to conserve energy, the target speed of the mowing motor should be reduced. In this case, the control unit of the mowing motor adjusts the motor's duty cycle, causing the speed of the mowing motor to decrease and approach the target speed until the actual speed of the mowing motor equals the target speed.

[0100] The multiple target speeds of the mowing motor increase or decrease sequentially. The control unit is configured to adjust the motor speed to the corresponding target speed based on the number of times the user operates the control unit. In this embodiment, the mowing motor includes three target speeds: 2800 RPM (Revolutions Per Minute), 3000 RPM, and 3200 RPM. The cutter diameter is 21 inches. The linear velocity (i.e., blade tip velocity) at the cutter tip when driven to rotate at these three target speeds is different, each adapting to different mowing needs. The control unit, which is directly controlled by the user, can be configured to have one or two trigger states.

[0101] In some optional embodiments, the control element has only one trigger state, and the mowing motor should be cyclically configured among multiple target speeds based on the number of times the control element is triggered to the trigger state. For example, in this embodiment, the above three target speeds are configured, which are defined as high, medium, and low, respectively. Assuming that the initial state of the mowing motor is the low target speed, when the control element is controlled to the trigger state once or twice, the speed of the mowing motor is configured to the medium and high target speeds in sequence. From the third time the trigger state is reached, it will cycle into the above target speeds. For example, when the trigger state is reached for the third time, it will enter the low target speed again, and when the trigger state is reached for the fourth time, it will enter the medium target speed, and so on. Furthermore, there are other implementation methods for the above cyclic configuration, such as a low, high, medium, low cyclic mode.

[0102] In addition, in other embodiments, the lawnmower motor may also include four or more target speeds. Those skilled in the art should be able to configure it in the above order without creative effort, and all such configurations should be included within the scope of protection of this embodiment.

[0103] In some alternative embodiments, the control unit includes two trigger states, such as a first trigger state and a second trigger state. The target speed of the mower motor should change differently depending on whether the control unit is in the two trigger states. For example, if the mower motor has three target speeds, defined as high, medium, and low, assuming the initial state of the mower motor is configured as a low target speed, when the control unit is in the first trigger state for the first and second times, the target speed of the mower motor is configured as medium and high target speeds, respectively. Conversely, if the initial state of the mower motor is configured as a high target speed, when the control unit is in the second trigger state for the first and second times, the target speed of the mower motor is configured as medium and low target speeds, respectively.

[0104] In summary, the target speed of the lawnmower motor can be switched in multiple sequences, and the switching sequence of the target speed differs depending on the trigger state of the control unit. Furthermore, the control unit can include even more trigger states, and the target speed of the lawnmower motor switches in different sequences under each trigger state.

[0105] It should be noted that in some embodiments, to reduce drastic changes in cutter speed due to user error, a target speed cyclical change of "high, medium, low, high" or "low, medium, high, low" control mode is generally not set. This is because such cyclical target speed control modes would cause excessively large changes in cutter speed within a short period of time; for example, rapidly increasing from the lowest speed to the highest speed or decreasing from the highest speed to the lowest speed. Especially when increasing directly from the lowest target speed to the highest speed, there is a high probability of experiencing significantly increased noise and vibration, resulting in an unpleasant user experience.

[0106] Therefore, the control unit is generally set to two trigger states, and the lawnmower motor is configured with multiple target speeds. When the control unit is in one of the trigger states, the lawnmower motor changes speed from the current speed to the highest speed by one gear until the lawnmower motor is configured to the highest speed gear. Conversely, when the control unit is in the other trigger state, the lawnmower motor changes speed from the current speed to the lowest speed by one gear until the lawnmower motor is configured to the lowest speed gear. In this embodiment, the user can configure the lawnmower motor to any target speed by controlling the control unit, and since there is no significant difference in the target speed before and after each speed target switch, there will be no problem of reduced user experience due to sudden speed changes.

[0107] In another optional embodiment, the control element is configured to include more than two trigger states, such as three trigger states. In this case, each trigger state should be associated with a target speed. That is, when the user sets the control element to one of the trigger states, the mowing motor changes towards a specific target speed; when the user sets the control element to another trigger state, the mowing motor changes towards another specific target speed. For example, in this embodiment, three trigger states are set, corresponding to high, medium, and low target speeds respectively. When the user configures the trigger element to a certain trigger state, the mowing motor is adjusted towards the corresponding target speed.

[0108] In a particular optional embodiment, the mowing motor is also equipped with an adaptive target speed. This adaptive target speed is not a constant value. Under this adaptive target speed, the garden vehicle enters a mower speed adaptive state, where the real-time speed of the mower changes with the density of the grass at the work location: when the grass is dense, the speed of the mower increases; when the grass is sparse, the speed of the mower decreases. This allows the mower to complete the mowing more economically, thus optimizing the relationship between the power of the mower and the density of the grass to be mowed, and balancing the relationship between the power consumption of the mower and the mowing efficiency.

[0109] In another alternative embodiment, the user-controlled actuator causes the mowing motor to switch between an adaptive target speed and other target speeds with constant speeds.

[0110] In another alternative embodiment, the travel assembly includes a travel motor for driving the drive wheels to rotate. The travel motor is configured with multiple speed ranges. The user controls the control unit to cause the control board to send a control signal to configure the speed range of the travel motor to one of the speed ranges. The multiple speed ranges of the travel motor have different maximum speeds. For example, the speed range of the travel motor can be configured as fast, medium, and slow speed ranges, with the maximum speed of the three speed ranges decreasing sequentially, and the minimum speed of the three speed ranges being zero. That is, when the travel motor is in various speed ranges, the lawnmower can start from a stationary state and travel to the maximum value of the current speed range.

[0111] In a specific implementation state, the lawnmower is operating at 50% of its maximum speed within the current speed range. When the user adjusts the lawnmower's speed range, the actual speed should also change. Specifically, when the lawnmower is adjusted from the slow speed range to the medium speed range, the speed should be adjusted from 50% of the maximum speed in the slow speed range to 50% of the maximum speed in the medium speed range. In summary, the multiple speed ranges configured for the drive motor in this embodiment are designed to make it easier and faster for users to set the lawnmower to their desired speed.

[0112] In particular, in one alternative embodiment, reference is made to the appendix. Figure 1 The active steering component is configured as a steering rod, which is pivoted on the frame 1 and the deflection angle of the steering rod is positively correlated with the speed of the drive motor. The steering rod can deflect forward or backward on the frame 1 about a first axis, and the steering rod has a first forward position deflected to the foremost position, a first backward position deflected to the rearmost position, and a middle position; the first axis is parallel to the left and right direction of the vehicle.

[0113] When the steering lever is in the center position, the drive motor does not rotate the drive wheels, and the vehicle is stationary. When the steering lever is in the first forward position, the real-time speed of the drive motor is equal to its maximum speed within the current speed range. When the steering lever is between the center and the first forward position, the real-time speed of the drive motor is less than the maximum speed within the current speed range, and the real-time speed of the drive motor increases as the steering lever continues to deflect towards the first forward position.

[0114] Furthermore, in an optional embodiment, the maximum speed of the multiple speed ranges of the drive motor increases sequentially, and the control unit is configured to sequentially configure the rotational speed range of the drive motor to the corresponding speed range according to the number of times the user operates it. That is, the multiple speed ranges of the aforementioned drive motor are set sequentially, and when the control unit is operated by the user, the speed range of the drive motor changes sequentially between the various rotational speed ranges.

[0115] As mentioned earlier, the control components used to control the speed range of the drive motor may have several trigger states.

[0116] In one optional embodiment, the control element for controlling the speed range of the drive motor has a trigger state. At this time, the drive motor should be cyclically configured in multiple speed ranges according to the number of times the control element is triggered to the trigger state. For example, this embodiment is configured with the above three speed ranges, which are defined as fast, medium and slow respectively.

[0117] In one optional embodiment, the speed range of the above-mentioned cyclic configuration is in the order of slow, medium, fast, slow; for example: assuming the initial state of the drive motor is a slow target speed, when the control unit is controlled to the trigger state once or twice, the speed of the mowing motor is configured to medium and fast target speeds in sequence; from the third time the trigger state is reached, it will cycle into the above-mentioned speed range, that is, when the trigger state is reached for the third time, the mowing motor is reconfigured to a slow target speed, when the trigger state is reached for the fourth time, the mowing motor is reconfigured to a medium target speed, and so on; furthermore, there are other implementation methods for the above-mentioned cyclic configuration, such as a fast, medium, slow, fast cycle, etc.

[0118] In another optional embodiment, the control element for controlling the speed range of the drive motor has two trigger states. When the control element is in the first trigger state, the drive motor changes between three speed ranges: fast, medium, and slow in a certain order. When the control element is in the second trigger state, the drive motor changes between three speed ranges: fast, medium, and slow in another order.

[0119] More specifically: When the control unit is in the first trigger state, the drive motor changes its speed range in the order of fast, medium and slow. For example, when the drive motor is currently in the fast speed range and the control unit is in the first trigger state, the drive motor changes to the medium speed range. When the control unit is in the first trigger state again, the drive motor changes to the slow speed range.

[0120] When the control unit is in the second trigger state, the drive motor changes its speed range in the order of slow, medium, and fast. For example, if the drive motor is currently in the slow speed range and the control unit is in the second trigger state, the drive motor changes to the medium speed range. When the control unit is in the second trigger state again, the drive motor changes to the fast speed range.

[0121] Additionally, referring to the aforementioned configuration where the target speed of the lawnmower motor is not cyclical, the drive motor can also have a similar configuration, meaning its speed range is not cyclical. This is also to avoid drastic changes in driving speed that could reduce the driving experience. For example, when the control is in the first trigger state, the drive motor sequentially changes its speed range in the order of fast, medium, and slow. When the drive motor is in the fast speed range, if the control is in the first trigger state again, the speed range of the drive motor will not change. Conversely, when the drive motor is in the slow speed range, if the control is in the second trigger state again, the speed range of the drive motor will also not change.

[0122] In another optional embodiment, the control unit can also be configured to include more than two trigger states, such as three trigger states. In this case, each trigger state should be associated with a speed range. That is, when the user sets the control unit to one of the trigger states, the drive motor changes to a specific speed range; when the user sets the control unit to another trigger state, the drive motor changes to another specific speed range. For example, in this embodiment, three trigger states are set, corresponding to fast, medium, and slow target speeds, respectively. When the user configures the trigger unit to a certain trigger state, the drive motor is adjusted to the corresponding target speed.

[0123] In other embodiments, the drive motor may be configured to include four or more speed ranges. Those skilled in the art should be able to configure it in the above order without creative effort, and all such configurations should be included within the protection scope of this embodiment.

[0124] Reference Appendix Figure 1 Appendix Figure 2 The steering levers include a first steering lever 2 and a second steering lever 3, the drive motor includes a first drive motor and a second drive motor, and the drive wheels include a first drive wheel and a second drive wheel. The user adjusts the deflection angle of the first steering lever 2 to adjust the rotational speed of the first drive wheel driven by the first drive motor, and the user adjusts the deflection angle of the second steering lever 3 to adjust the rotational speed of the second drive wheel driven by the second drive motor. When there is a difference in the deflection angles of the two steering levers, the drive motors will drive the drive wheels at different speeds, resulting in a speed difference between the two drive wheels, thus causing the garden vehicle to steer.

[0125] In another alternative embodiment, the function of one or more of the controls can be defined by the user. For example, if one or more controls are currently used to adjust the speed range of the drive motor, the aforementioned one or more controls can be configured to adjust the target speed of the lawnmower motor by using another control on the control handle 4 or a button in another location on the vehicle. Alternatively, the aforementioned controls can also be configured to adjust angle deviation thresholds, signal strength thresholds, or preset field strength thresholds, etc.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] The aforementioned display-enabled devices can be configured as a lamp board or light strip 7 with a number of LEDs (see attached diagram). Figure 2 Alternatively, a display screen; furthermore, the light panel or light 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.

[0130] 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.

[0131] In another optional embodiment, the display area can also be used to change its display effect according to the functional state of the cutting table 8. The cutting table 8 includes three speed ranges: high, medium, and low. The display area displays different patterns or text when the cutter is in different speed ranges. As mentioned above, when the cutter switches between high and low speeds, the display area should switch its display state.

[0132] In another optional embodiment, the display area is set as a light strip 7 configured on the steering stalk. When the rotational speed of the drive wheel or the cutter changes, the color of the light strip 7 also changes. For example, at a lower speed, the light strip 7 displays a relatively soothing color such as green, while when the drive wheel or the cutting table 8 is at a high speed, the light strip 7 displays a relatively more eye-catching color such as red, thereby reminding the user and people around the vehicle to keep a certain distance from the vehicle.

[0133] In another alternative embodiment, the above-mentioned light strip 7 can also produce a flashing technical effect. For example, when the rotational speed of the drive wheel or the cutter is relatively low, the flashing frequency of the light strip 7 changes. For example, at a relatively low rotational speed, the light strip 7 flashes at a relatively low frequency, while when the drive wheel or the cutter bar 8 is at a high rotational speed or high load, the light strip 7 flashes at a relatively high frequency, thereby reminding the user and the people around the vehicle to keep a certain distance from the vehicle.

[0134] In another alternative embodiment, the above-mentioned light strip 7 can also achieve different patterns by the opening and closing of internal partial lamp beads, such as displaying Chinese characters, English characters, punctuation marks, etc.; for example, at a relatively low rotational speed, the light strip 7 displays characters such as "safe" or "安全" through the local opening and closing of the lamp beads at various places inside; at a relatively high rotational speed, 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 through the opening and closing of the lamp beads inside the light strip 7 for easier observation.

[0135] In another alternative embodiment, several of the color, flashing frequency, and display character change can be selected for the above-mentioned light strip 7 simultaneously, which should not be understood as breaking through the protection scope of this embodiment.

[0136] In another alternative embodiment, at least two functional mechanisms further include a power display module, and the power display module displays different patterns or texts according to the remaining power of the power supply system 6. Further, the above-mentioned power display module is a power display area 415 configured at the control handle 4. Since the control handle 4 is located at the end of the steering rod and the user standing or sitting on the vehicle faces the control handle 4, the power display area 415 is also configured at the position of the control handle 4 facing the user's face, so that the user can relatively easily obtain the remaining power information of the vehicle.

[0137] Further, referring to Appendix Figure 1 、Appendix Figure 3 、Appendix Figure 10 , the power display area 415 is composed of several power display units configured in the control handle 4.

[0138] In one of the alternative embodiments, the number of power display units is one, and different remaining powers are indicated by different colors displayed by the power display unit. For example, when the power supply system 6 is at a high power, it is displayed as green, at a medium power, it is displayed as yellow, and at a low power, it is displayed as red.

[0139] In another optional embodiment, the power display area 415 can be configured to emit both red and green light. When the power system 6 is fully charged, red light is not displayed, and green light is displayed at maximum brightness. When the power system 6 is nearly depleted, green light is not displayed, and 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 of the power system 6 is consumed, the brightness of the green light gradually decreases, while the brightness of the red light gradually increases. In this embodiment, when the power system 6 has 50% remaining power, both the green and red lights in the power display area 415 are at medium brightness. At this time, the two colors of light overlap, allowing the user to see yellow light, which conforms to the conventional practice of using color to display power. Furthermore, the colors displayed in the power display area 415 exhibit a gradient effect.

[0140] Furthermore, please refer to the appendix again. Figure 10 The figure shows that the power display area 415 includes multiple power display units (a single rectangle in the power display area 415 in the figure is a single power display unit). In this embodiment, each power display unit can be lit up individually. At this time, the number of lit power display units can be used to represent the amount of remaining power. As shown in the figure, there are four power display units, that is, a single power display unit represents 25% of the power. That is, when the first, second, third and fourth power display units are lit up, it represents that the remaining power of the power system 6 is 25%, 50%, 75% and 100%, respectively.

[0141] In other embodiments, to alleviate users' battery anxiety, the number of lit battery display units and the remaining battery level can be redefined. For example: when the battery level is above 50%, all four battery display units are lit; when the battery level is above 25% and below 50%, three battery display units are lit; when the battery level is above 10% and below 25%, two battery display units are lit; when the battery level is above 5% and below 10%, only one battery display unit is lit; and when the battery level is below 5%, no battery display unit is lit.

[0142] In other embodiments, the battery level can be displayed in different ways depending on the user habits of the region.

[0143] In other embodiments, the power display area can be configured as a screen, displaying power information in various forms such as numerical percentage, battery icon color changes, and battery icon fill areas. (See attached document.) Figure 11 The image shows the battery display area with a battery icon and battery percentage.

[0144] In another optional embodiment, the control element is configured as a control switch, which includes at least two states, one of which is equivalent to the aforementioned trigger state. For example, if the control switch is a push-button switch, its initial state is a non-trigger state, and its pressed state is a trigger state.

[0145] In another optional embodiment, the control switch can also be selected from various forms such as a slide switch, rocker switch, rotary switch, button switch, toggle switch, and touch screen switch. The control switch can have multiple trigger states, such as a rotary switch with four states, one of which is a non-trigger state, and the other three are trigger states, each corresponding to a different functional state of the mechanism. When the rotary switch is used to control the target speed of the lawnmower motor, and in this embodiment, the multi-functional garden vehicle is equipped with three target speeds, the three trigger states each correspond to one of the target speeds. This rotary switch, as a control switch, makes it easier for the user to adjust the speed. The user can also quickly determine the current target speed of the multi-functional vehicle by observing the state of the rotary switch. The implementation methods of the slide switch and rocker switch are similar to those of the rotary switch and will not be described in detail.

[0146] It should be noted that when the above-mentioned control switches are selected in various forms such as slide switches, rocker switches, and rotary switches, they all include at least one trigger state. When the above-mentioned switches only include one trigger state, the specific operation method is as described above and will not be repeated.

[0147] Reference Appendix Figure 11 In another optional embodiment, the control handle 4 is equipped with a touch screen, which can be operated by the user. The control element is the control area on the touch screen. When the control area is touched by the user, it controls any functional mechanism to produce a functional state change through the control panel. As a part of the touch screen, the function of the control area can be defined by the user. For example, if the function of a certain control area is originally defined as controlling the target speed change of the lawnmower motor, the user can redefine the control area to control the speed range change of the drive motor. In summary, the touch screen configured on the control handle 4 can be configured with at least one control area, which can be defined to control any functional mechanism to produce a functional state change; and when the user needs to control another functional mechanism, the control area can be redefined so that the control area can produce a control effect on the other functional mechanism.

[0148] In one alternative embodiment, reference is made to the appendix. Figure 11The diagram shows a touchscreen located on the control handle 4 of the first turn lever 3. The display screen is divided into upper and lower areas; the upper area is the display area, and the lower area is the control area. As shown, the left side of the display area shows the current remaining power of the power system 6; the right side shows the status of the lights. Flashing left and right arrows indicate that the corresponding lights are flashing, indicating turn signal activation. The high beam or low beam icons are lit when the corresponding status is active.

[0149] In one alternative embodiment, reference is made to the appendix. Figure 12 The diagram shows a touchscreen located at the control handle 4 on the second steering lever 4. The display screen is divided into upper and lower areas; the upper area is the display area, and the lower area is the control area. As shown, the left side of the display area shows the rotational speed of the cutter in the header 8 in thousands of revolutions per minute, while the right side shows the vehicle's speed in kilometers per hour.

[0150] Reference Appendix Figure 11 Appendix Figure 12 The control area in the figure includes setting controls marked with "M" and arrow controls. The setting controls and arrow controls work together to change the content displayed in the display area, or to enable the aforementioned controls to adjust the functional state of the functional mechanism.

[0151] Furthermore, the control element is set to perform specific functions of the arrow control element, allowing the arrow control element to select from multiple preset selectable functions; for example, the preset selectable functions of the control element set by the first control handle include: controlling the headlight to switch between high beam and low beam modes, or controlling one of the light strips 7 to flash to present the technical effect of a turn signal, or turning one of the function switches on and off, etc.

[0152] The setting control element of the second control handle is used to change the specific function of the adjustment button, so that the arrow control element can select from multiple preset selectable functions. The preset selectable functions include: controlling the target speed of the lawnmower motor, or controlling the speed range or angle deviation threshold of the travel motor, or adjusting the preset field strength threshold, or adjusting the preset signal strength threshold, etc.

[0153] Furthermore, in the embodiment where the control handle 4 is equipped with a touch screen, the control area and display area can also be configured in various other ways, such as displaying a scroll wheel-like graphic in the control area, allowing the user to adjust any functional mechanism by sliding the touch screen on the scroll wheel-like graphic. Those skilled in the art can configure the control area and display area in other ways without inventive effort, and all such modifications should be included within the scope of protection of this application.

[0154] In this embodiment, the steering lever is equipped with a control element coupled to the controller system. The control element is used to control at least one functional mechanism to produce a functional state change when operated by the user. In this embodiment, the control element is wired to the controller system via signal line 13.

[0155] The signal line 13 is connected to the controller system in sequence via the control element, the steering rod, and the frame 1. Since there is relative movement between the steering rod and the frame 1, the signal line 13 can be physically divided into a frame 1 line portion fixed to the frame 1, a steering rod line portion fixed to the steering rod, and a free line portion located between the frame 1 line portion and the steering rod line portion.

[0156] Reference Appendix Figure 1 Appendix Figure 2 The garden vehicle in this embodiment includes a first steering rod 2 and a second steering rod 3, which are respectively arranged on the left and right sides of the vehicle to control the operation of the walking components on the corresponding sides. A control handle 4 is provided on the steering rod, which can control some functions of the garden vehicle. A light strip is also provided on the steering rod, which can be lit to display certain information.

[0157] In one alternative embodiment, the garden vehicle includes a light fixture located on the front or rear side of the vehicle, the light fixture being operable to change its brightness or direction of illumination.

[0158] Reference Appendix Figure 1 In one alternative embodiment, the garden vehicle is also equipped with a charging port 9 for charging the power system 6.

[0159] Reference Appendix Figure 3 The control element is located on the side of the steering rod away from the frame 1. A swing arm 11 is fixedly connected to the lower part of the steering rod, and the swing arm 11 is rotatably connected to the frame 1 to allow the steering rod to rotate relative to the frame 1. The steering rod is a tubular structure, and the wiring harness leading from the control element extends through the interior of the steering rod to the swing arm 11, and is arranged along the outer wall of the swing arm 11. (See attached diagram) Figure 3 Appendix Figure 4 The figure shows a schematic diagram of the structure of the first steering rod 2 and the corresponding swing arm 11. A pressure plate 12 is disposed outside the swing arm 11, and a wire groove for accommodating the wire harness is disposed at the connection between the swing arm 11 and the pressure plate 12.

[0160] Specifically, see the attached document. Figure 3 The lower end of the first steering rod 2 is fixed with a connecting plate 10, and the upper end of the swing arm 11 is fixed with the connecting plate 10.

[0161] In one alternative embodiment, reference is made to the appendix. Figure 6The groove is formed on the side wall of the pressure plate 12 near the swing arm 11. It is easy to manufacture as long as a continuous groove is machined on the pressure plate 12. In other embodiments, the groove can also be formed on the swing arm 11.

[0162] Reference Appendix Figure 4 Appendix Figure 5 The vehicle frame 1 is fixedly equipped with a mounting plate 14, which is provided with a retaining member for fixing a portion of the signal line 13. As mentioned above, a portion of the signal line 13 is fixed to the swing arm 11 by the wire groove and the pressure plate 12, and the swing arm 11 and the steering rod maintain a relatively fixed positional relationship; another portion of the signal line 13 is fixed to the mounting plate 14 by the retaining member, and the mounting plate 14 and the vehicle frame 1 maintain a relatively fixed positional relationship. The signal line 13 is thus divided into a frame 1 line portion fixed to the vehicle frame 1, a steering rod line portion fixed to the steering rod, and a free line portion located between the frame 1 line portion and the steering rod line portion. The aforementioned retaining member position is the boundary position between the free line portion and the frame 1 line portion.

[0163] Reference Appendix Figure 4 Appendix Figure 5 The mounting plate 14 has a wire hole 141 through which the signal wire 13 passes. A retainer fixes the signal wire 13 to the wire hole 141. That is, the signal wire 13 on one side of the wire hole 141 is a free wire portion, and the other side of the wire hole 141 is the frame wire portion. Furthermore, the mounting plate 14 also has a mounting hole 142 near the wire hole 141. The retainer is a cable tie (not shown) that passes through the mounting hole 142 and the wire hole 141 and binds the signal wire 13.

[0164] Furthermore, as mentioned above, the steering rod rotates around the first axis 15 between the first forward position, the intermediate position, and the first reverse position. That is, the rotating rod section of the signal line 13 rotates with the steering rod around the first axis 15 and generates relative motion with respect to the line section of the frame 1. The free line section located in the intermediate position is used to keep the steering rod connected to the signal of the controller system during the rotation of the steering rod around the first axis 15.

[0165] Specifically, when the steering lever is in the center position, the vehicle's drive wheels do not rotate, and the vehicle is stationary. When the steering lever is in the first forward position, the real-time rotational speed of the drive wheels approaches the maximum rotational speed. When the steering lever is between the center position and the first forward position, the real-time rotational speed of the drive wheels is less than the maximum rotational speed, and the real-time rotational speed of the drive wheels increases as the steering lever continues to deflect towards the first forward position.

[0166] In one optional embodiment, the distance between the free line portion and the first axis 15 is at least partially less than 100mm. The relatively small distance reduces the amount of movement of the free line portion when the steering rod rotates around the first axis 15. That is, the free line portion only needs to retain a small length margin to meet the rotation of the steering rod around the first axis 15. The problem of the free line portion being straightened or even restricting the rotation of the steering rod when the steering rod rotates around the first axis 15 to a certain position will not occur.

[0167] In another optional embodiment, the distance between the junction of the free line portion and the frame line portion and the first axis 15 is less than 100mm, that is, the distance between the aforementioned retaining member and the first axis 15 is less than 100mm.

[0168] In another optional embodiment, the distance between the junction of the free line portion and the frame line portion and the first axis 15 is less than 50mm, that is, the distance between the retainer and the first axis 15 is less than 50mm. As shown in the figure, a shaft for rotating the steering rod around the first axis 15 is arranged at the first axis 15. The retainer maintains a certain distance from this shaft to avoid interference between the signal line 13 and the shaft. Therefore, configuring the distance between the retainer and the first axis 15 to be less than 50mm can better achieve the above-mentioned technical effect.

[0169] Reference Appendix Figure 8 In the figure, d1 is the distance between the retainer and the first axis 15. With d1 = 50mm and the maximum angle of the steering rod deviating from the middle position in the front-rear direction being 20°, the minimum reserved length for the free line part to move around the first axis 15 is the first reserved length. The first reserved length is the arc length with a radius of 50mm and a central angle of 20°. The calculated first reserved length is 17.5mm.

[0170] Comprehensive Reference Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 , attached Figure 5 The circular diagram inside the center hole 141 shows the cross-section of the signal line 13 at that location. Figure 6 The circle on one side of the location indicated by reference numeral 13 in the attached diagram also represents the cross-section of signal line 13 at that location. Figure 5 Appendix Figure 7 In the figure, reference numeral 15 indicates the first axis 15, and the distance between the above-mentioned cross-section and the first axis 15 is the distance between the above-mentioned free line portion and the first axis 15.

[0171] Reference Appendix Figure 3 In one optional embodiment, the steering lever also rotates about a second axis 16 in the left-right direction of the vehicle, the second axis 16 being parallel to the vehicle's direction of travel. The direction of rotation of the steering lever about the second axis 16 is referenced in the appendix. Figure 4The direction indicated by the curved arrow. Specifically, the steering lever is configured such that when it moves around the second axis 16 to the outside of the vehicle, the vehicle is in a parked state, and the steering lever cannot rotate around the first axis 15. When the steering lever moves around the second axis 16 to the inside of the vehicle, the vehicle is in a drivable state, and the steering lever can rotate around the first axis 15.

[0172] In one optional embodiment, the distance between the free line portion and the second axis 16 is at least partially less than 100 mm. This relatively small distance reduces the amount of movement of the free line portion of the signal line 13 as the steering rod rotates around the second axis 16. In other words, the free line portion only needs to retain a small length allowance to satisfy the steering rod's rotation around the second axis 16; thus, the problem of the free line portion being straightened or even restricting the steering rod's rotation when it rotates to a certain position around the second axis 16 is avoided.

[0173] In another optional embodiment, the distance between the junction of the free line portion and the rotating rod portion and the second axis 16 is less than 100mm. That is, the minimum distance between the aforementioned pressure plate 12 and the second axis 16 is less than 100mm.

[0174] In another alternative embodiment, refer to the appendix Figure 6 The distance between the junction of the free line portion and the rotating rod portion and the second axis 16 is less than 50mm, that is, the distance between the aforementioned pressure plate 12 and the second axis 16 is less than 50mm. Figure 3 As shown, a shaft for rotating the steering rod around the second axis 16 is provided at the second axis 16. The retaining member maintains a certain distance from the shaft to avoid interference between the signal line 13 and the shaft. Therefore, the distance between the retaining member and the second axis 16 is configured to be less than 50mm to better achieve the above-mentioned technical effect.

[0175] Reference Appendix Figure 7 In the figure, d2 is the distance between the pressure plate 12 and the second axis 16. With d2 = 50mm and the maximum angle of the steering rod deviating from the middle position in the front-rear direction being 35°, the minimum reserved length for the free line part to move around the second axis 16 is the second reserved length. The second reserved length is the arc length with a radius of 50mm and a central angle of 35°. The calculated second reserved length is 27.9mm.

[0176] Furthermore, in one alternative embodiment, the steering rod can only deflect outward around the second axis 16 when it moves to the middle position around the first axis 15. The signal line 13 is in the initial state when the steering rod is in the middle position. Therefore, it is not necessary to reserve both the first and second reserved lengths at the same time. That is, only the second reserved length needs to be reserved to satisfy the normal deflection of the steering rod under the above conditions.

[0177] When the reserved length of signal line 13 is selected to be greater than 27.9mm, such as 28.5mm, the vibration generated during vehicle operation is relatively limited. Even if there is a small amount of friction with the frame 1, the friction position is easy to control. At this time, it is only necessary to add protective measures such as protective sleeves at the corresponding positions. The overall amount of friction is relatively controllable and there will be no serious wear or even communication interruption caused by the vibration of signal line 13.

[0178] Furthermore, in another alternative embodiment, d1 and d2 can be further reduced, thereby further shortening the required reserved length. In this case, the signal line 13 will generate less vibration during vehicle operation, and the problem of vibration and wear caused by the reserved length of the signal line 13 can be better avoided.

[0179] In another alternative embodiment, refer to the appendix Figure 9 The free wire portion of the aforementioned signal line 13 is wound into a spiral portion 17. The spiral structure of the spiral portion 17 makes it elastic. When it is stretched, it can be significantly elongated to ensure that the free wire portion has a significant length margin. When it is not stretched, it can be shortened to occupy less space and reduce the probability of it interfering with other parts of the vehicle.

[0180] In the embodiment where the free line portion is wound into a spiral shape, the distance between the free line portion and the first axis 15 is the shortest distance between them.

[0181] In summary, regarding the arrangement of the signal line 13, this specification discloses an implementation method to prevent interference between the signal line 13 and components such as the vehicle frame 1 due to steering lever movement. Specifically, by limiting the position of the free line portion relative to the steering lever's pivot point, the amount of movement of the free line portion during steering lever rotation is reduced, thereby preventing excessive movement of the free line portion of the signal line 13 during steering lever rotation and even interference with components such as the vehicle frame 1. Furthermore, this also avoids malfunctions such as severe wear of the signal line 13 during long-term use of the garden vehicle.

[0182] In another alternative embodiment, refer to the appendix Figure 1 The garden vehicle disclosed in this embodiment also includes a seat 5 for carrying the user. When driving the garden vehicle, the user sits on the seat 5 and holds the steering lever to drive the vehicle. During the driving process, the user can operate the control components on the steering lever as needed, thereby changing a certain functional mechanism to produce a change in functional state.

[0183] It should be further noted that in the above embodiment where the controller system is connected via signal line 13, the controller system used to control the functional mechanism to change its functional state is existing technology, and it can be transmitted via wired signal using conventional communication methods, which will not be elaborated here.

[0184] Further, see attached document. Figure 1 In the above embodiments, the gardening operation component is illustrated by the movement of the mower 8, and the multi-functional garden vehicle in this embodiment is a lawnmower. Furthermore, if the gardening operation component is a snow sweeping component, then the multi-functional garden vehicle is a snow sweeper. That is, the gardening operation component, as the main functional component of the multi-functional garden vehicle, can be changed according to the user's selection. Additionally, in some embodiments, the above-mentioned gardening operation component can also be a component that the user can replace according to actual needs. For example, removing the mower 8 used for mowing and replacing it with a sweeping disc for sweeping transforms the lawnmower into a sweeper. In summary, replacing the gardening operation component with any functional component according to user needs should not be construed as exceeding the protection scope of this embodiment.

[0185] For the same purpose, in another aspect, embodiments of this specification also provide a rideable lawnmower, which includes a frame 1, a cutter head 8, a walking assembly, a seat 5, and a power system 6; the seat 5 is disposed on the frame 1 and is used for a user to sit on, a steering lever and a handle are disposed in front of the seat 5, and the steering lever can rotate about a first axis 15 parallel to the left and right direction of the vehicle, so that when the user sits on the seat 5 and raises his arm forward with his arm naturally extended, he can relatively easily hold the steering lever.

[0186] For the same purpose, in another aspect, embodiments of this specification also provide a standing lawnmower, which includes a frame 1, a cutter head 8, a walking assembly, a standing platform, and a power system 6; the standing platform is disposed on the frame 1 and is used for a user to sit on, a steering rod and a handle are disposed in front of the standing platform, and the steering rod is rotatable about a first axis 15 parallel to the left and right direction of the vehicle, so that the user can relatively easily grasp the steering rod when standing on the standing platform and raising his arm forward.

[0187] For the same purpose, in another aspect, embodiments of this specification also provide a multi-functional work vehicle, which includes a frame 1, functional mechanisms, a controller system, a steering rod, etc.; the steering rod is rotatable about a first axis 15 parallel to the left and right direction of the vehicle, and when the user holds and deflects the steering rod, the user can control the vehicle to drive or steer.

[0188] In the above embodiments of the riding lawnmower, standing lawnmower, and multi-functional work vehicle, the aforementioned steering rod and signal line are all included. The signal line includes a frame line portion fixed to the frame, a swivel line portion fixed to the steering rod, and a free line portion located between the frame line portion and the swivel line portion. The distance between the free line portion and the first axis is at least partially less than 100mm, so as to avoid the signal line from being too easy to arrange and to avoid the signal line from easily interfering with the frame and other components during the rotation of the steering rod.

[0189] Furthermore, the frame 1 described in this specification extends at least partially in a direction parallel to the front-rear direction, and a user platform may be mounted on the frame. The user platform is used to accommodate the operator of the multi-functional vehicle and may include at least one of a seat or a standing platform. Figure 1 The example shown only illustrates the scenario where the user platform is configured as seat 5. Seat 5 or the standing platform is used for work involving sitting or standing. That is, the multi-functional vehicle can provide either a riding or standing work mode. Furthermore, the structures of the seat and the standing platform can be flexibly switched, meaning the working mode of the multi-functional vehicle can be flexibly switched between riding and standing work modes according to the actual needs of the user.

[0190] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0191] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0192] This utility model is not limited to the specific embodiments described above. Those skilled in the art will readily understand that many alternative solutions exist for the lawnmower and control handle of this utility model without departing from the principles and scope of this utility model. The scope of protection of this utility model is defined by the claims.
