Description

[0001] This application claims priority to Chinese Patent Application No. 202410849015.9, filed on June 27, 2024, the entire contents of which are incorporated herein by reference. [Technical Field]

[0002] 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]

[0003] Garden vehicles generally refer to vehicles used for outdoor gardening operations, mainly including vehicles used for garden cutting and maintenance.

[0004] Take lawnmowers as an example: Among garden vehicles, lawnmowers are one of the fastest-growing garden operation vehicles in recent years. They are equipped with a cutting platform for cutting and maintaining grass, as well as other functional mechanisms. When operating, the blades in the cutting platform rotate at high speed to cut the grass. In addition, the vehicle may also move relatively quickly. These actions may cause injury to people nearby. However, existing lawnmowers do not have equipment to inform people nearby, making it impossible for them to quickly know the status of the lawnmower in order to determine whether it is in a working state that is not suitable for approaching.

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

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-functional garden vehicle that enables nearby personnel to quickly know the status of the lawnmower in order to determine whether the lawnmower is in a working state that is not suitable for approach.

[0045] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," and "rear," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. 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.

[0046] 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. The term "fixed connection" in this utility model should also be broadly interpreted as integrally formed, welded, or connected by other fasteners.

[0047] 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.

[0048] 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.

[0049] To achieve the above objectives, embodiments of this specification disclose a multifunctional garden vehicle, including a frame 1, functional mechanisms, and a power system 6. The frame 1 extends along the vehicle's forward direction, and the power system 6 and the functional mechanisms are both connected to the frame 1. The power system 6 is used to supply power to at least one of the functional mechanisms. Furthermore, the power system 6 can also supply power to other electronic components in the garden vehicle, such as a human-machine interface system.

[0050] The aforementioned power system 6 is mounted on the vehicle frame 1 and is partially detachably connected to the vehicle frame 1. The power system 6 includes multiple battery units. The multiple battery units can be at least one of a first-specification battery pack and 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, battery internal resistance, weight, size, energy density, cell type, charge information, and battery health status information.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] In this embodiment, at least two types of functional mechanisms are configured. The functional mechanisms include garden operation components, walking components, and other components used to enable the multi-functional garden vehicle to change its functional state. The garden operation components are used to perform garden maintenance operations, and the walking components are driven to the drive wheels on the left and right sides of the frame 1 to drive the multi-functional garden vehicle.

[0059] Another embodiment of this specification also discloses a multi-functional garden vehicle, which includes a frame, a user platform, a battery pack, functional mechanisms, and a controller system as described above. The user platform is configured on the frame and is used to carry the user. The battery pack is detachably configured on the vehicle and is used to supply power to various components of the vehicle. The functional mechanisms are configured on the frame and are used to perform various specific functions of the vehicle. The controller system is used to control at least one of the functional mechanisms to produce functional state changes.

[0060] In some optional embodiments, the controller system includes a VCU (Vehicle Control Unit), which is a core electronic control unit used to make vehicle control decisions.

[0061] The functional components include at least a walking assembly and a gardening operation component. The walking assembly is connected to the frame and is used to drive the multi-functional garden vehicle. Driving the vehicle is the specific function of the walking assembly, and the forward, backward, and turning movements are the actual effects produced by changes in the functional state of the walking assembly. The gardening operation component is connected to the frame and is used to perform gardening operations, such as a lawn mowing component and a garden trimming component. Mowing lawns and trimming trees are the specific functions of the corresponding gardening operation component, and the starting, stopping, and power changes of the gardening operation component are the changes in its functional state.

[0062] In other optional embodiments, the functional mechanism also includes components capable of changing functional states, such as a display screen, a sound-emitting unit, or a garden work component position adjustment device. For example, the display screen is configured on the vehicle frame and used to display various images or text information to the user; the sound-emitting unit is configured on the vehicle frame and used to emit sounds to remind the user or external personnel; and the garden work component position adjustment device is configured on the vehicle frame and used to adjust the position of the garden work component. More specifically, the garden work component adjustment device includes an electric lifting assembly that operates when the user or controller system issues a garden work component position adjustment signal, changing at least one of the garden work component's height, front-rear position, left-right position, and angle, thereby facilitating the garden vehicle to achieve the expected operating conditions.

[0063] In some optional embodiments, to facilitate user control of the vehicle's movement, the multi-functional garden vehicle further includes an active steering component operatively coupled to the walking component for controlling the vehicle's movement. The active steering component is configured with a recess for accommodating a light strip 7, which, after being positioned within the recess, does not protrude beyond the outer contour of the active steering component. The light strip 7 itself has low structural strength; its placement within the recess reduces direct contact with the outside, lowering the likelihood of damage from impacts.

[0064] In some optional embodiments, the light strip 7 is configured as an electrically emitting component that can transmit signals to a user or people around the vehicle by emitting light.

[0065] In some optional embodiments, the light strip 7 is disposed on the side of the active steering assembly facing the front of the vehicle, that is, the light emitted by the light strip 7 is directed towards the front of the vehicle, which can effectively transmit various signals to the front of the vehicle through light, such as indicating to the outside world whether the vehicle is currently in a high-load working state with a high degree of danger.

[0066] In some more specific embodiments, when the drive wheels in the vehicle's running gear are operating at high speed, the vehicle is traveling at a relatively high speed. At this time, the warning message "Danger, Do Not Approach" can be conveyed to the outside world through the warning color or rapid flashing of the light strip 7. The warning color includes colors that are easy to attract people's attention, such as red and yellow.

[0067] In some more specific embodiments, when the vehicle's gardening components are operating, or even under heavy load, the area around the vehicle is in a relatively dangerous state, and a danger signal should be transmitted to the outside world. Taking a zero-steering lawnmower or other lawnmowers as an example, the gardening component of the lawnmower is the cutter head 8, which is equipped with high-speed rotating blades. When the high-speed rotating blades are operating, they may throw out grass clippings and small stones, which may cause injury to people who approach. Therefore, the light strip 7 can also convey the message "Danger, Do Not Approach" to the outside world through warning colors or rapid flashing.

[0068] As mentioned above, the light strip 7 located in front of the vehicle can display the approximate working status of the vehicle to the front of the vehicle, improving the safety of the vehicle during operation.

[0069] In some optional embodiments, reference is made to the appendix. Figure 1 , Figure 2 The multi-functional garden vehicle active steering assembly includes two steering rods located on the left and right sides of the vehicle, respectively, as shown in the attached diagram. Figure 1 The figure shows the first steering lever 2 and the second steering lever 3, with appended details. Figure 1 Appendix Figure 2 The two steering rods are in different positions. Figure 1 The steering rod in the middle is relative to the attached Figure 2 The steering lever rotates inward, allowing it to rotate forward and backward. The vehicle's running gear includes drive wheels located on both sides of the vehicle. The user controls the corresponding drive wheels via two steering levers. The two drive wheels rotate at different speeds when the deflection of the two steering levers is different, thus achieving vehicle steering.

[0070] In some optional embodiments, the light strips 7 on the two steering stalks are at least partially located on both sides of the user platform, that is, there is a clear gap between the light strips 7 on the two steering stalks, so that the general outline of the vehicle can be judged by the outside world through the light strips 7. Especially in environments where it is difficult to observe the garden vehicle, such as in poor light or heavy fog, the presence of the light strips 7 can greatly improve the overall safety of the vehicle.

[0071] In some optional embodiments, the active steering assembly is configured as a steering rod that is at least partially curved, the steering rod comprising at least two straight rod sections angled to each other and a curved rod section located between the two straight rod sections. (See attached figure) Figure 3 Appendix Figure 4 The diagram shows a single steering rod with two curved sections, meaning a single steering rod has three straight sections. (See attached image.) Figure 4In the figure, P1 and P3 are two straight sections, and P2, located between P1 and P3, is one of the curved sections. The figure also shows another curved section that is different from P2 but is not marked. The part of this other curved section away from P1 is the third straight section that is not marked.

[0072] In some optional embodiments, the light strip 7 includes at least two straight light sections arranged at an angle to each other and a curved light section located between the two straight light sections. That is, the outline of the light strip 7 is roughly similar to the outline of the turn signal stalk, making it easy for external observers to determine the outline of the turn signal stalk through the light strip 7. (Refer again to the appendix...) Figure 4 The light strip 7 corresponding to positions P1 and P3 in the diagram is the straight section of the light, and the light strip 7 corresponding to position P2 in the diagram is the curved section of the light; similarly, the attached... Figure 4 The light strip 7 shown also has three straight light sections and two curved light sections.

[0073] In some optional embodiments, the steering stalk is at least partially composed of a front stalk portion and a rear stalk portion, which are connected by a threaded fastener, and the light strip 7 and the fastener do not coincide in the orthographic projection in the vehicle's longitudinal direction. (See attached diagram.) Figure 3 The figure shows bolt holes 75 used to configure the fastener.

[0074] In some optional embodiments, one straight segment of the steering rod extends along a first straight line, the orthographic projection of the straight segment in the vehicle's longitudinal direction being symmetrical with respect to a second straight line, the second straight line being parallel to the first straight line. (See attached figure.) Figure 4 Taking the straight line segment indicated by marker P1 as an example: Straight line Q is the aforementioned second straight line. Straight line Q is located in the middle of the straight line segment, and the orthographic projection of the light strip 7 in the vehicle's longitudinal direction does not intersect the second straight line. That is, the portion of the light strip 7 corresponding to this straight line segment is located on one side of the second straight line. The orthographic projection of the fasteners that fix the front and rear poles in the vehicle's longitudinal direction intersects the second straight line.

[0075] In some optional embodiments, the light strip 7 and the second straight line are approximately coincident in the orthographic projection of the vehicle in the longitudinal direction. That is, when viewed from the front of the vehicle towards the steering stalk, the light strip 7 is approximately centered in the middle of the steering stalk, and threaded fasteners are located on both sides of the steering stalk.

[0076] In some optional embodiments, the steering stalk includes a front stalk portion and a rear stalk portion as described above, the front stalk portion facing forward of the vehicle and having the aforementioned notch 702 for the light strip 7 to pass through.

[0077] In some optional embodiments, reference is made to the appendix. Figure 8The figure shows a partial cross-sectional view of the steering rod (light strip 7 is not shown). The steering rod is also provided with a support member 701 for supporting the front and rear rod sections. The fasteners that fit into the bolt holes 75 further fix the front and rear rod sections to the support rod. In this embodiment, the support member 701 is a rod-shaped or tubular structure made of metal, forming the general shape of the steering rod.

[0078] In some optional embodiments, a limiting member is provided inside the front pole, and the light strip 7 is restrained in the recess at least by the limiting member to prevent the position of the light strip 7 from changing.

[0079] In some more specific embodiments, reference is made to the appendix. Figure 8 The front pole is provided with at least a first limiting member 703 and a second limiting member 704 located on both sides of the recess, for fixing the light strip on both sides.

[0080] In some more specific embodiments, reference is made to the appendix. Figure 8 The light strip, which is set in the recessed area, is simultaneously abutted by the first limiting member 703, the second limiting member 704, and the supporting member 701, thus completing the complete fixation of the light strip.

[0081] In some optional embodiments, the light strip 7 includes an FPCB (Flexible Printed Circuit Board), which is a circuit board made of a flexible substrate and features bendability, lightweight, and small size, making it easy to install on partially curved turn bars.

[0082] In some optional embodiments, the light strip 7 disposed on the active steering assembly has at least a partial dimension greater than 5 mm and less than 15 mm in the vehicle's longitudinal direction. (See attached figure.) Figure 6 The figure shows one cross-sectional view of the light strip 7. X1, as indicated in the figure, represents the thickness of the light strip 7 on the side facing outwards from the active steering assembly. X2, as indicated in the figure, represents the thickness of the light strip 7 on the side facing inwards from the active steering assembly. Y, as indicated in the figure, represents the width of the light strip along the vehicle's longitudinal direction. The light strip 7 is disposed within the active steering assembly, and the aforementioned 5mm ≤ Y ≤ 15mm.

[0083] In some optional embodiments, reference is made to the appendix. Figure 6 The figure shows one cross-sectional view of the light strip 7, which includes a light-shielding layer 71 and a light-transmitting portion 72 penetrating a portion of the light-shielding layer 71, the light-transmitting portion 72 facing forward of the vehicle. As described above, the light strip 7 also includes an FPCB board 73 and LED chips 74 disposed on the FPCB board 73, the light emitted by the LED chips 74 passing through the light-transmitting portion 72 and projecting outward. Figure 7As shown in the figure, X1 is the size of the portion of the light-transmitting part 72 that penetrates the light-shielding layer 71, and X2 is the external size of the light-shielding layer 71. In this embodiment, X1 is smaller than X2, and X1 is slightly smaller than the width of the recess so that the light-transmitting part 72 can pass through the recess and emit light to the outside of the turn rod. X2 is larger than the width of the recess so as to prevent the light strip 7 from falling off from the recess.

[0084] In some optional embodiments, the flexible printed circuit board has a plurality of light-emitting units arranged along its length, and the density of light-emitting units in at least a portion of the flexible printed circuit board of the light strip 7 is 100 to 150 units per meter, with each light-emitting unit being individually controllable. The higher density of light-emitting units allows the light strip 7 to achieve more diverse lighting effects over a shorter length.

[0085] In some more specific embodiments, the light-emitting unit is selected from LED beads.

[0086] In some optional embodiments, the distance between the light strip 7 and the end of the steering stalk is greater than 50mm and less than or equal to 300mm, where the end of the steering stalk is the end of the steering stalk furthest from the frame 1. As mentioned above, the steering stalk serves to allow the user to control the vehicle's movement, and the user needs to hold the end of the steering stalk or a position close to the end. At least a portion of the distance between the light strip 7 and the end of the steering stalk constitutes the position for the user to hold the stalk. (See attached diagram.) Figure 5 In the diagram, Z represents the distance between light strip 7 and the end of the turn signal stalk, which is 50mm ≤ Z ≤ 300mm. Furthermore, in... Figure 5 In the embodiment shown, a control handle 4 is provided at the end of the steering lever. The control handle is provided with an operation switch that controls at least the light strip 7. The area between the light strip 7 and the control handle is the position for the user to hold, that is, the position indicated by the mark W in the figure is the position for the user to hold. The light strip 7 is not provided in this part to avoid the light strip 7 affecting the user's grip.

[0087] In another optional embodiment, the distance between the light strip 7 and the end of the turn signal stalk is greater than 100mm and less than or equal to 300mm.

[0088] In one optional embodiment, the multi-functional garden vehicle includes a controller system for controlling at least one functional mechanism to produce functional state changes; the active steering assembly is equipped with a control board connected to the controller system, and the control board is electrically connected to the light strip 7. The controller system determines the vehicle's state by acquiring the working states of the walking assembly and garden operation components, and then sends a control signal to the control board. Based on the received control signal, the control board controls the light strip 7 to emit light of a predetermined color and / or flash at a predetermined frequency.

[0089] In one of the more specific embodiments, the active steering component includes an operating switch coupled to the control board and used to control the light strip 7, the operating switch being used at least to control the on / off of the light strip 7 and / or the switching of the operating mode of the light strip 7.

[0090] In one of the more specific embodiments, the active steering component includes at least two operating switches coupled to the control board, at least one of which is used to control the opening and closing of the light strip 7 and / or the switching of the working mode of the light strip 7, and at least one of the operating switches controls a functional mechanism and causes it to produce a functional state change.

[0091] In some optional embodiments, the light strip 7 includes light-emitting units capable of emitting red, green, and blue light individually, that is, the light strip 7 includes RGB light-emitting units, which can use the combination of the three primary colors to achieve specific hues and brightness, thereby realizing the display of various lighting effects.

[0092] In some optional embodiments, reference is made to the appendix. Figure 6 At least two reinforcing terminals 76 are provided in the recess for accommodating the light strip 7, and the reinforcing terminals 76 are connected to both sides of the recess of the active steering assembly. The recess of the steering rod extends through the aforementioned front rod portion, and the light strip 7 extends outward from the inside of the steering rod during installation, so that the light-emitting surface of the light strip 7 extends to the outside of the steering rod through the recess. The aforementioned recess forms a narrow gap in the steering rod, and the connection of the reinforcing terminals 76 to both sides of the recess can increase the strength of the corresponding position of the steering rod, avoiding the technical problem of steering rod breakage during long-term use.

[0093] In some optional embodiments, the spacing between two adjacent reinforcing terminals 76 is less than or equal to 100mm, which can effectively increase the strength of the steering rod. In some optional embodiments, the spacing between two adjacent reinforcing terminals 76 is greater than or equal to 30mm, because the reinforcing terminals 76 will block the light from the light strip 7, and setting the reinforcing terminals 76 too densely will affect the actual visual effect of the light strip 7.

[0094] In another optional embodiment, the recess of the active steering component for configuring the light strip 7 is provided with a transparent lamp cover (not shown) to make the outer contour of the portion of the active steering component for configuring the light strip 7 smooth, and the transparency of the lamp cover does not obstruct the light emitted by the light strip 7. It should be noted that in this embodiment, although the transparent lamp cover ensures that there is no exposed recessed portion on the outer contour of the active steering component at the light strip 7, a recess for accommodating the light strip 7 still exists below the lamp cover, and the sidewalls of the recess are made of the same material as at least other parts of the active steering component. That is, this embodiment should not be construed as exceeding the scope of protection regarding the "recess" in the claims.

[0095] This specification also provides another optional embodiment, which discloses a ride-on lawnmower, including a frame 1, a seat 5, a battery pack, and a functional mechanism. The seat 5 is configured with the frame 1 and provides seating for a user. The battery pack is detachably connected to the lawnmower and supplies power to the ride-on lawnmower. The functional mechanism is configured with the frame 1 and performs specific functions of the ride-on lawnmower; the functional mechanism includes a walking assembly connected to the frame 1 for driving the ride-on lawnmower and a cutter head 8 connected to the frame 1 for performing mowing operations.

[0096] The ride-on lawnmower also includes the active steering assembly described above, which is operatively coupled to the walking assembly for controlling the movement of the multi-functional garden vehicle. The active steering assembly is configured with a recess for accommodating the light strip 7, which, after being positioned in the recess, does not protrude beyond the outer contour of the active steering assembly. This reduces the contact between the light strip 7 located within the recess and the outside environment, lowering the possibility of damage from impacts.

[0097] Reference Appendix Figure 1 In another part of the embodiments of this specification, a multi-functional garden vehicle is also disclosed. The garden vehicle includes a frame 1, functional mechanisms, a power system 6, and a controller system. The functional mechanisms are configured on the frame 1 and are used to perform various specific functions of the vehicle. The power system 6 is configured on the vehicle and is used to supply power to the functional mechanisms and other components of the vehicle. The controller system is used to control at least one of the functional mechanisms to produce functional state changes.

[0098] In some optional embodiments, the multi-functional garden vehicle also includes a user platform configured on the chassis 1 for carrying the user.

[0099] In some optional embodiments, the controller system includes a VCU (Vehicle Control Unit), which is a core electronic control unit used to make vehicle control decisions.

[0100] In some optional embodiments, to facilitate user control of the vehicle's movement, the multi-functional garden vehicle also includes an active steering component operatively coupled to the walking component for controlling the movement of the multi-functional garden vehicle.

[0101] In some optional embodiments, the active steering component is configured with a light strip 7 facing forward of the vehicle for displaying vehicle status information by being at least partially illuminated. In some optional embodiments, the light strip 7 is configured as an electrically emitting component that can transmit signals to a user or persons around the vehicle by emitting light.

[0102] In some optional embodiments, the aforementioned functional mechanism includes at least a walking component and a gardening operation component. The walking component is connected to the frame 1 and is used to drive the multi-functional gardening vehicle. Driving the vehicle is the specific function of the walking component, and the forward, backward, and turning movements of the vehicle are the actual effects of changes in the functional state of the walking component. The gardening operation component is connected to the frame 1 and is used to perform gardening operations, such as a lawn mowing component and a garden trimming component. Mowing lawns and trimming trees are the specific functions of the corresponding gardening operation component, and the starting, stopping, and power changes of the gardening operation component are the changes in the functional state of the gardening operation component.

[0103] In other optional embodiments, the functional mechanism also includes components capable of changing functional states, such as a display screen, a sound-emitting unit, or a garden work component position adjustment device. For example, the display screen is configured on the frame 1 and used to display various images or text information to the user; the sound-emitting unit is configured on the frame 1 and used to emit sounds to remind the user or external personnel; and the garden work component position adjustment device is configured on the frame 1 and used to adjust the position of the garden work component. More specifically, the garden work component adjustment device includes an electric lifting assembly that operates when the user or controller system issues a garden work component position adjustment signal, changing at least one of the garden work component's height, front-rear position, left-right position, and angle, thereby facilitating the garden vehicle to achieve the expected operating conditions.

[0104] In some optional embodiments, as described above, the light strip 7 is disposed on the side of the active steering assembly facing the front of the vehicle, that is, the light emitted by the light strip 7 faces the front of the vehicle, which can effectively transmit various signals to the front of the vehicle through light, such as indicating to the outside world whether the vehicle is currently in a high-load working state with a high degree of danger.

[0105] In some more specific embodiments, when the drive wheels in the vehicle's running gear are operating at high speed, the vehicle is traveling at a relatively high speed. At this time, the warning message "Danger, Do Not Approach" can be conveyed to the outside world through the warning color or rapid flashing of the light strip 7. The warning color includes colors that are easy to attract people's attention, such as red and yellow.

[0106] In some more specific embodiments, when the vehicle's gardening components are operating, or even under heavy load, the area around the vehicle is in a relatively dangerous state, and a danger signal should be transmitted to the outside world. Taking a zero-steering lawnmower or other lawnmowers as an example, the gardening component of the lawnmower is the cutter head 8, which is equipped with high-speed rotating blades. When the high-speed rotating blades are operating, they may throw out grass clippings and small stones, which may cause injury to people who approach. Therefore, the light strip 7 can also convey the message "Danger, Do Not Approach" to the outside world through warning colors or rapid flashing.

[0107] The active steering assembly is configured with a recess for accommodating the light strip 7, which is positioned in the recess and does not protrude from the outer contour of the active steering assembly. The light strip 7 itself has low structural strength, and its placement in the recess reduces its direct contact with the outside, thereby reducing the possibility of damage to the light strip 7 from impacts.

[0108] In one more specific embodiment, the active steering component includes a control board coupled to the controller system and the light strip 7. The control board receives control signals from the controller system, processes them, and sends them to the light strip 7, causing the light strip 7 to emit light in a predetermined manner.

[0109] In one of the more specific embodiments, the active steering component includes an operating switch coupled to the control board and used to control the light strip 7, the operating switch being used at least to control the on / off of the light strip 7 and / or the switching of the operating mode of the light strip 7.

[0110] In one of the more specific embodiments, the active steering component includes at least two operating switches coupled to the control board, at least one of which is used to control the opening and closing of the light strip 7 and / or the switching of the working mode of the light strip 7, and at least one of the operating switches controls a functional mechanism and causes it to produce a functional state change.

[0111] In one of the more specific embodiments, the active steering component is configured as a steering rod that rotates in a controlled manner about a first axis between a first forward position, a mid-position, and a first reverse position, the first axis being parallel to the left-right direction of the vehicle.

[0112] In one more specific embodiment, the multi-functional garden vehicle includes two steering rods, and the vehicle's running gear includes drive wheels located on both sides of the vehicle. The user controls the corresponding drive wheels through the two steering rods. The two drive wheels rotate at different speeds when the deflection of the two steering rods is different, thereby achieving vehicle steering.

[0113] In some optional embodiments, the multi-functional garden vehicle includes a user platform for carrying users. The light strips 7 on the two steering stalks are at least partially located on both sides of the user platform, meaning there is a clear gap between the light strips 7 on the two steering stalks. This allows the approximate outline of the vehicle to be determined by the light strips 7, especially in environments where it is difficult to observe the garden vehicle, such as in low light or heavy fog. The presence of the light strips 7 can significantly improve the overall safety of the vehicle.

[0114] In some optional embodiments, the active steering component includes a grip portion for the user to hold, which does not overlap with the light strip 7 in the left-right direction of the vehicle. That is, the light strip 7 is not located in the main grip position on the active steering component, to avoid the light strip 7 affecting the user's grip comfort. In this embodiment, the grip portion only refers to the main grip position on the active steering component and does not mean that the non-grip portion of the active steering component cannot be gripped by the user.

[0115] In some optional embodiments, the active steering assembly is configured as a steering rod as described above, with one end of the steering rod connected to the frame 1, and the end of the steering rod away from the frame 1 defined as the steering rod end. The grip portion, which is mainly for the user to hold, is close to the steering rod end, and the steering rod ends of the two steering rods are close to each other, making it convenient for the user to hold them with both hands.

[0116] In some optional embodiments, the distance between the light strip 7 and the end of the steering stalk is greater than 50mm and less than or equal to 300mm, where the end of the steering stalk is the end of the steering stalk furthest from the vehicle frame 1. As mentioned earlier, the steering stalk serves to allow the user to control the vehicle's movement, and the user needs to hold the end of the steering stalk; the distance between the light strip 7 and the end of the steering stalk is the position for the user to hold it. (See attached diagram.) Figure 5 The W marked in the figure is the position for the user to hold. The light strip 7 is not installed in this part to avoid affecting the user's grip.

[0117] In another optional embodiment, the distance between the light strip 7 and the end of the turn signal stalk is greater than 100mm and less than or equal to 300mm.

[0118] In some optional embodiments, the light strip 7 includes an FPCB (Flexible Printed Circuit Board), which is a circuit board made of a flexible substrate and features bendability, lightweight, and small size, making it easy to install on partially curved turn bars.

[0119] In some optional embodiments, the flexible printed circuit board has a plurality of light-emitting units arranged along its length, and the density of light-emitting units in at least a portion of the flexible printed circuit board of the light strip 7 is 100 to 150 units per meter, with each light-emitting unit being individually controllable. The higher density of light-emitting units allows the light strip 7 to achieve more diverse lighting effects over a shorter length.

[0120] In some more specific embodiments, the light-emitting unit uses an RGB light source.

[0121] In one more specific embodiment, the RGB light source includes LED beads 74 and a color control module. The color control module controls the LED beads 74 to display the corresponding color according to the color control data sent by the control board. That is, the color control module of each RGB light source controls the color of the LED beads 74 according to the control signal sent by the control board, and each RGB light source can emit different light according to the control signal. When each of the RGB light sources of the light strip 7 needs to display different colors, the color control module in each RGB light source operates according to the different contents of the control signal.

[0122] Reference Appendix Figure 9 The figure shows that both steering rods are equipped with control boards and light strips 7. The RGB light sources in the light strips 7 are connected in series, and the color control modules of adjacent RGB light sources are connected in signal.

[0123] In one more specific embodiment, the RGB light source density of at least a portion of the flexible printed circuit board of the light strip 7 is 100-150 LEDs per meter. Its relatively high RGB light source density allows it to display richer lighting effects, especially when displaying flowing light effects, where the higher density of RGB light sources can display the lighting effect with smoother color changes.

[0124] In some optional embodiments, the light strip 7 disposed on the active steering assembly has at least a partial dimension greater than 5 mm and less than 15 mm in the vehicle's longitudinal direction. (See attached figure.) Figure 7 The figure shows a cross-sectional view of the light strip 7. X1 represents the thickness of the light strip 7 facing outwards from the active steering assembly, X2 represents the thickness of the light strip 7 facing inwards from the active steering assembly, and Y represents the width along the vehicle's longitudinal direction. The light strip 7 is disposed within the active steering assembly, and the thickness is 5mm ≤ Y ≤ 15mm.

[0125] In some optional embodiments, reference is made to the appendix. Figure 7 The figure shows a cross-sectional schematic diagram of the light strip 7, which includes a light-shielding layer 71 and a light-transmitting portion 72 penetrating a portion of the light-shielding layer 71, the light-transmitting portion 72 facing forward of the vehicle. As mentioned above, the light strip 7 also includes an FPCB board 73 and LED beads 74 disposed on the FPCB board 73, the light emitted by the LED beads 74 passing through the light-transmitting portion 72 and projecting outward. Figure 7As shown in the figure, X1 is the size of the portion of the light-transmitting part 72 that penetrates the light-shielding layer 71, and X2 is the external size of the light-shielding layer 71. In this embodiment, X1 is smaller than X2, and X1 is slightly smaller than the width of the recess so that the light-transmitting part 72 can pass through the recess and emit light to the outside of the turn rod. X2 is larger than the width of the recess so as to prevent the light strip 7 from falling off from the recess.

[0126] In one optional embodiment, the RGB light source includes three color channels representing red, green, and blue, respectively. Each color channel corresponds to 8 bits of binary data representing color intensity. Red, green, and blue are the three primary colors of light, and they can display more colors through different proportions. When the RGB light source emits red, green, and blue light of equal intensity simultaneously, it displays white light. The binary data of each color channel is the color signal received by the color control module. Eight bits of binary data can represent 256 color intensities, meaning a single color channel can support 256 color intensity variations. For a single RGB light source, this translates to over ten million color variations, satisfying all color representation needs.

[0127] The control board sends at least 24N bits of binary data to the light strip 7 in a single transmission. Each RGB light source extracts 24 bits of this data and sends the remaining data to the next RGB light source, where N is the number of RGB light sources. Each 8-bit binary code in the above binary data represents one of the colors red, green, and blue. When the control board sends a light control signal to the light strip 7, the RGB light sources extract and save the received control signal data, and then send the remaining control signal data to the next RGB light source connected in series, until all control signal data is extracted and saved by the corresponding RGB light source. This allows for the control of multiple RGB light sources via a single bus.

[0128] As mentioned above, the lighting control signal data sent by the control board to the light strip 7 includes at least 24N bits of binary data, the purpose of which is to ensure that each RGB light source can receive the corresponding control signal.

[0129] In some optional embodiments, the control board has a built-in control mode for controlling the light strip 7, in which the light strip 7 operates in a breathing mode and / or a flowing mode.

[0130] In breathing mode, the brightness of at least a portion of the RGB light source of the light strip 7 changes periodically;

[0131] In the flowing mode, the RGB light source of the light strip 7 changes color sequentially in a preset order.

[0132] In one of the more specific embodiments, the breathing mode and the flowing mode are not implemented simultaneously. That is, during certain time periods, the RGB light sources of the light strip 7 only produce periodic brightness changes while the color of a single RGB light source remains unchanged. During other time periods, the RGB light sources of the light strip 7 only produce color changes while the brightness of a single RGB light source remains unchanged.

[0133] In another, more specific embodiment, the breathing mode and the flowing mode are implemented simultaneously. That is, during certain periods of time, the RGB light source of the light strip 7 not only produces periodic changes in brightness, but the color of each individual RGB light source also changes.

[0134] It is important to note that the brightness change of the RGB light source in breathing mode only represents the observed brightness change, and does not refer to the color change of a single red, green, or blue light within the RGB light source. This is because one way for an RGB light source to produce brightness changes is by synchronizing the brightness of the three colors of light. For example, a signal (255, 255, 255) represents standard pure white light, while a signal (200, 200, 200) represents slightly lower intensity white light. As mentioned above, the red, green, and blue light emitted by a single LED 74 in the RGB light source all change, but the actual displayed light is a slightly lower intensity white. Therefore, it should be understood as the aforementioned brightness change.

[0135] In some optional embodiments, the brightness change curve of the light strip 7 in breathing mode is a stepped waveform or a smooth sine wave. A stepped waveform represents intermittent, visually noticeable abrupt changes in the brightness of at least some of the RGB light sources in the light strip 7. A smooth sine wave, on the other hand, indicates that the brightness of at least some of the RGB light sources changes slowly, with a slower rate of change and less abruptness.

[0136] In one of the optional embodiments, when the operating parameters of the multi-functional garden vehicle reach an operating threshold, the controller system is configured to control the light strip 7 to operate at a warning breathing frequency. The aforementioned operating parameters reaching the operating threshold indicates that the vehicle's operating state has reached a predetermined condition, at which point a warning signal should be sent to the outside world via the light strip 7.

[0137] In one of the optional embodiments, the controller system is configured to control the light strip 7 to operate at an alarm breathing frequency, including: the controller system sending an alarm command to a control board; and in response to the control board receiving the alarm command, the control board controlling at least a portion of the RGB light sources of the light strip 7 to operate at a breathing frequency of 1 to 5 times per second. That is, at least a portion of the RGB light sources flash 1 to 5 times per second, a frequency that can effectively achieve an alarm effect.

[0138] In one of the more specific embodiments, when the light strip 7 operates at an alarm breathing frequency, at least a portion of the RGB light source of the light strip 7 emits red light.

[0139] In some optional embodiments, the operating condition threshold includes any one of the following: driving speed threshold, power supply threshold, load power threshold, vehicle body angle threshold, and vehicle body slip threshold:

[0140] The operating parameters corresponding to the driving speed threshold are the driving speed parameters of the multi-functional garden vehicle. When the vehicle speed is high, the vehicle's danger factor should be considered high. At this time, the above-mentioned warning breathing frequency should be used to issue a danger warning to the outside world to prevent outside users from approaching the vehicle because they do not recognize the danger.

[0141] The operating parameters corresponding to the power threshold are the input or output power parameters of the power system 6. When the input or output power of the power supply is too high, a danger warning should also be issued to the outside world. Specifically, during charging, if the input power of the power supply is too high, it may indicate that the vehicle's power management module or charger is damaged. A danger signal should be displayed to external users through a warning breathing frequency to remind them to intervene in time to avoid danger. During discharging, if the output power of the power supply is too high, it indicates that the vehicle may be operating under high load. If external personnel approach, they may be injured. A danger signal should be displayed to external personnel through a warning breathing frequency to remind them not to approach to avoid danger.

[0142] The operating parameters corresponding to the aforementioned load power threshold are the load power parameters of the garden operation components. As mentioned above, when the load power is too high, it may also be in a dangerous state, requiring warnings and reminders. Furthermore, if the load on a local structure of the vehicle is too high, it may also be in a dangerous state, such as the walking mechanism or garden operation components. Taking a zero-steering lawnmower or other lawnmowers as an example, the garden operation component of the lawnmower is the cutter head 8, which is equipped with a high-speed rotating blade. During operation, the high-speed rotating blade may throw out grass clippings and small stones, which could injure people who approach. Therefore, the light strip 7 can also convey the message "Danger, Do Not Approach" to the outside world through warning colors or rapid flashing.

[0143] The operating parameters corresponding to the vehicle body angle threshold are the tilt angle parameters of the garden operation vehicle relative to the horizontal plane; when the vehicle is driving or operating on a slope, if the slope angle is large, the vehicle may overturn or other dangerous situations, so the above-mentioned danger signals should also be displayed.

[0144] The operating parameter corresponding to the vehicle body slip threshold is the difference between the actual displacement of the landscaping vehicle and the expected displacement of the vehicle. The vehicle is equipped with components such as an IMU or positioning system that can sense the actual displacement and acceleration signals of the vehicle. If the actual movement of the vehicle does not match the expected movement, wheel slippage and other loss of control phenomena are likely to occur. In this case, the aforementioned danger warning signal should also be displayed.

[0145] In some optional embodiments, when the light strip 7 is in flowing mode, the time interval between the color changes of two adjacent RGB light sources is 0.05 to 0.5 seconds. It should be noted that: in this embodiment, the flowing mode may not only be a flowing effect produced by actual color changes, but also a flowing effect caused by the synchronous changes of the three colors of light in the RGB light source, resulting in a flowing effect of brightness changes.

[0146] In some optional embodiments, when the light strip 7 is in flowing mode, at least one of the RGB light sources changes color after a first time interval, and at least one of the RGB light sources has the same color as one of the adjacent RGB light sources before the first time interval. This creates the visual effect of one of the RGB light sources moving, producing a flowing visual effect.

[0147] As described above, the RGB light sources of LED strip 7 are controlled by the control board of the active steering component, which sends out N 24-bit binary data. Each RGB light source displays a different color according to the order of the binary data signals sent by the control board. The flowing light effect is achieved by the control board changing the order of the N 24-bit binary data, causing at least one RGB light source to emit light in the color of the adjacent RGB light source in the previous time period.

[0148] In some optional embodiments, when the light strip 7 is in flowing mode:

[0149] At least two adjacent RGB light sources among five consecutive RGB light sources must satisfy |ΔR|≤10;

[0150] At least two adjacent RGB light sources in a series of five consecutive RGB light sources must satisfy 10 ≤ |ΔG| ≤ 20;

[0151] At least two adjacent RGB light sources in any three consecutive RGB light sources must satisfy |ΔB|≤5;

[0152] In some optional embodiments, when the light strip 7 is in flowing mode, at least 50% of the RGB values ​​of two adjacent RGB light sources satisfy: |ΔR|+|ΔG|+|ΔB|≤30.

[0153] In some optional embodiments, when the light strip 7 is in flowing mode, at least 70% of the RGB values ​​of two adjacent RGB light sources satisfy: |ΔR|+|ΔG|+|ΔB|≤30.

[0154] Where |ΔR| is the absolute value of the difference between the RGB values ​​of the red color channel of two adjacent RGB light sources;

[0155] Where |ΔG| is the absolute value of the difference between the RGB values ​​of the green channel of two adjacent RGB light sources;

[0156] Where |ΔB| is the absolute value of the difference between the RGB values ​​of the blue color channel of two adjacent RGB light sources.

[0157] The RGB values ​​of the red, green, and blue color channels mentioned above are the decimal data of the corresponding color channels of the RGB light source. For example, the binary data executed by one of the RGB light sources is (11111111, 00000000, 00000000), and its corresponding RGB value is (255, 0, 0), corresponding to the color red. The RGB values ​​of the red, green, and blue color channels are 255, 0, and 0, respectively.

[0158] For example, when a light strip 7 containing 40 RGB light sources performs a flowing light effect, it receives a set of control signals as follows:

[0159] {0,226,216},{2,216,218},{3,203,222},{5,190,226},{7,174,230},{8,158,235},{11,141,240},{15,125,244},{18,109,248},{23,95,251},

[0160] {29,83,254},{37,74,255},{46,65,255},{52,75,255},{60,55,255},{65,45,255},{73,46,255},{80,46,255},{89,38,255},{130,30,255}

[0161] {118,26,255},{130,26,255},{142,26,255},{148,26,255},{152,26,255},{151,30,254},{143,42,251},{132,60,247},{117,80,244},{100,104,239},

[0162] {81,127,234},{81,127,234},{61,151,229},{61,151,229},{43,175,225},{25,196,222},{11,213,218},{11,213,218},{1,227,216},{1,227,216}

[0163] Then the first two RGB light sources have |ΔR| = 2, |ΔG| = 2, and |ΔB| = 2.

[0164] Among the first 5 RGB light sources, the |ΔR| of any two adjacent RGB light sources are 2, 1, 2, and 2, respectively.

[0165] The |ΔG| values ​​for any two adjacent RGB light sources among the first five RGB light sources are 10, 13, 13, and 13, respectively.

[0166] Among the first three RGB light sources, the |ΔB| of any two adjacent RGB light sources is 2 and 4, respectively.

[0167] As mentioned above, at least the data of |ΔR|, |ΔG|, and |ΔB| of adjacent RGB light sources are relatively small, meaning that the color difference between two adjacent RGB light sources is small. This prevents abrupt color changes when implementing flowing light effects, resulting in smoother flowing light effects.

[0168] The calculation results of |ΔR|+|ΔG|+|ΔB| for two adjacent RGB light sources in the above 40 sets of data include 39 data points, as shown in the table below:

[0169] 14 18 19 22 22 25 24 23 22 21 18 18 16 28 15 9 7 17 49 16 12 12 6 4 6 23 33 38 46 47 0 49 0 46 42 35 0 26 0 /

[0170] Of these, 30 had values ​​less than 30, accounting for approximately 77%.

[0171] That is, when the light strip 7 in this embodiment executes the flowing mode, 77% of the RGB values ​​of two adjacent RGB light sources satisfy: |ΔR|+|ΔG|+|ΔB|≤30.

[0172] In another optional embodiment, when the light strip 7 is in flowing mode, at least 70% of the RGB values ​​of two adjacent RGB light sources satisfy: |ΔR|+|ΔG|+|ΔB|≤30.

[0173] In another optional embodiment, when the light strip 7 is in flowing mode, at least 60% of the RGB values ​​of two adjacent RGB light sources satisfy: |ΔR|+|ΔG|+|ΔB|≤30.

[0174] In another optional embodiment, when the light strip 7 is in flowing mode, at least 50% of the RGB values ​​of two adjacent RGB light sources satisfy: |ΔR|+|ΔG|+|ΔB|≤30.

[0175] In other words, the above 40 binary data are ordered by the control board and sent to the light strip 7 again to realize the flowing light effect of the light strip 7. Moreover, the |ΔR|+|ΔG|+|ΔB| of each two adjacent RGB light sources is small, and at least half of them are less than 30. It can be effectively assumed that the color difference between two adjacent RGB light sources is small, and there will be no color abrupt effect in the visual effect. That is, the visual effect of the flowing light effect is smoother.

[0176] In some optional embodiments, in response to the active steering component being manually controlled by the user to turn the vehicle to the left, at least a portion of the RGB light sources of at least one of the light strips 7 are illuminated sequentially from right to left. That is, when the vehicle has a steering intention, the corresponding side of the light strip 7 displays a flowing light effect. For example, when the vehicle turns left, the left light strip 7 displays a flowing light effect. More specifically, the left light strip 7 displays a visual effect of light flowing to the left.

[0177] In some optional embodiments, in response to the active steering component being manually controlled by the user to turn the vehicle to the right, at least a portion of the RGB light sources of at least one of the light strips 7 are illuminated sequentially from left to right. That is, when the vehicle turns right, the right light strip 7 displays a flowing light effect. More specifically, the right light strip 7 displays a visual effect of light flowing to the right.

[0178] This specification also provides another optional embodiment, which discloses a ride-on lawnmower, including a frame 1, a user platform, functional mechanisms, a power system 6, and a controller system. The user platform is configured as a seat 5 connected to the frame 1 and for the user to sit on. The power system includes a battery pack detachably connected to the lawnmower for supplying power to the ride-on lawnmower. The functional mechanisms are configured on the frame 1 and for performing specific functions of the ride-on lawnmower; the functional mechanisms include a walking assembly connected to the frame 1 for driving the ride-on lawnmower and a cutter head 8 connected to the frame 1 for performing mowing operations.

[0179] The ride-on lawnmower also includes a steering rod as described above and a light strip 7; the steering rod is operatively coupled to the walking assembly for controlling the movement of the multi-functional garden vehicle; the light strip 7 is disposed on the steering rod and faces forward of the ride-on lawnmower for displaying status information of the ride-on lawnmower by being at least partially illuminated. In some optional embodiments, the light strip 7 is configured as an electrically emitting component that can transmit signals to the user or people around the vehicle by emitting light.

[0180] In some optional embodiments, the aforementioned functional mechanism includes at least a walking component and a gardening operation component. The walking component is connected to the frame 1 and is used to drive the multi-functional gardening vehicle. Driving the vehicle is the specific function of the walking component, and the forward, backward, and turning movements of the vehicle are the actual effects of changes in the functional state of the walking component. The gardening operation component is connected to the frame 1 and is used to perform gardening operations, such as a lawn mowing component and a garden trimming component. Mowing lawns and trimming trees are the specific functions of the corresponding gardening operation component, and the starting, stopping, and power changes of the gardening operation component are the changes in the functional state of the gardening operation component.

[0181] In other optional embodiments, the functional mechanism also includes components capable of changing functional states, such as a display screen, a sound-emitting unit, or a garden work component position adjustment device. For example, the display screen is configured on the frame 1 and used to display various images or text information to the user; the sound-emitting unit is configured on the frame 1 and used to emit sounds to remind the user or external personnel; and the garden work component position adjustment device is configured on the frame 1 and used to adjust the position of the garden work component. More specifically, the garden work component adjustment device includes an electric lifting assembly that operates when the user or controller system issues a garden work component position adjustment signal, changing at least one of the garden work component's height, front-rear position, left-right position, and angle, thereby facilitating the garden vehicle to achieve the expected operating conditions.

[0182] In some optional embodiments, as described above, the light strip 7 is disposed on the side of the active steering assembly facing the front of the vehicle, that is, the light emitted by the light strip 7 faces the front of the vehicle, which can effectively transmit various signals to the front of the vehicle through light, such as indicating to the outside world whether the vehicle is currently in a high-load working state with a high degree of danger.

[0183] 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 provided on the frame 1. The user platform is used to carry the operator of the multi-functional vehicle and may include at least one of a seat 5 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 seat 5 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.
