[0001] This invention relates to the field of vehicle engineering technology, and in particular to a rideable lawnmower and a multi-functional work vehicle. [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: 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.

[0004] In the field of garden or outdoor work vehicles such as lawnmowers, users need to constantly hold and frequently look at the components that control the vehicle's movement while it is in operation. Users do not have enough time to look at the display screen, which makes it difficult for the display screen to effectively show the user the vehicle's status information.

[0005] Therefore, it is particularly important to propose a multi-functional work vehicle that can solve the above-mentioned technical problems. [Summary of the Invention]

[0103] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," and "rear" that 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, and 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 a limitation of the invention.

[0104] Unless otherwise specified, the terms "set," "connected," and "linked" in this invention 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 invention should also be broadly understood to mean integrally formed, welded, or connected by other fasteners.

[0105] This embodiment discloses a multi-functional work vehicle, as shown in the attached document. Figure 1 The vehicle includes a frame 1, an outdoor work component, and a seat 5. The frame 1 extends along a first direction, which is also the forward direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work. The seat 5 is disposed on the frame 1 and is used to carry the user.

[0106] To enhance the vehicle's aesthetics, it is typically equipped with side panels on the left and / or right and / or rear sides. In one optional embodiment, refer to the attached... Figure 1 The multi-functional work vehicle includes a side cover 2, shown in the figure, located on the right side of the vehicle. The side cover 2 is also equipped with a display screen assembly 3, which can display patterns or character information to the user when powered on. In another optional embodiment, the side cover 2 with the display screen can also be located on the left side of the vehicle. In yet another optional embodiment, side covers 2 are located on both the left and right sides of the vehicle, and display screen assemblies 3 capable of displaying patterns or character information to the user are located on both sides. It should be noted that, to ensure the side cover 2 is relatively stable in the vehicle's position, it is fixed to the frame 1 using bolts or other fasteners.

[0107] In some optional embodiments, the seat 5 includes a cushion and a backrest, the backrest being for the user to lean against when sitting on the cushion. Looking forward from the top center of the backrest, the outer front profile of the vehicle's side, located in front of the display assembly 3, is visible. In this embodiment, the display assembly 3, capable of displaying patterns or character information to the user, is positioned on one side of the vehicle, and the outer front profile on the side of the display assembly is not obstructed by the display assembly 3 and remains visible. This means that the user can determine the vehicle's position relative to objects on the ground by observing the outer front profile, preventing errors in the driving route due to an inability to determine the vehicle's position.

[0108] It should be noted that the top of the backrest of seat 5 is the closest physical position to the user's head in the vehicle. Therefore, looking forward from the center of the top of the backrest is approximately the line of sight of a user sitting in seat 5 looking forward. Therefore, refer to the appendix... Figure 2 The front side outline of the vehicle in front of the display assembly 3 is visible to the user seated in seat 5, meaning the user's line of sight can see the ground through the front side outline of the vehicle. Figure 2 The shaded area mentioned above is the area where the user can see the ground along the front side outline of the vehicle. The aforementioned front side outline of the vehicle is the outer outline looking towards the front of the vehicle from the head of the user who is driving the vehicle.

[0109] When performing outdoor ground work, the work vehicle initially travels in a straight line. Upon reaching the edge of the work area, it reverses its direction and travels in the opposite direction. The outdoor work components slightly overlap with the already worked area to ensure no work is missed. In this embodiment, when the overlapping area is located on the side of the vehicle closer to the display assembly 3, the display assembly 3 may obstruct the edge of the outdoor work components. However, as mentioned above, the outer contour of the wheels in front of the display assembly 3 is visible to the user sitting in seat 5. For the same user, the coverage area of ​​the vehicle's outdoor work components remains constant relative to the user's view of the vehicle's outer contour. Therefore, the user can determine the degree of overlap between the coverage area of ​​the outdoor work components and the already worked area by observing the positional relationship between the boundary of the already worked area and the vehicle's outer contour. In other words, the user determines the degree of overlap between the coverage area of ​​the outdoor work components and the already worked area by observing the position of the boundary of the already worked area relative to the vehicle's outer contour in their field of vision. This avoids missing any work areas after the work is completed.

[0110] In some optional embodiments, the multi-functional work vehicle further includes a passive wheel 8 disposed at the front of the frame 1 on one side of the display assembly 3, see attached figure. Figure 1 The multi-functional work vehicle shown in the figure includes two omnidirectional wheels located at the front of the vehicle. The omnidirectional wheel located on one side of the display assembly 3 is the aforementioned passive wheel 8, which is located on the part of the vehicle closest to the front edge.

[0111] In this embodiment, when looking forward from the top center of the backrest towards the front of the vehicle, the passive wheel 8 is at least partially visible without being obstructed by the display screen assembly 3. That is, at least a portion of the passive wheel 8 can be seen by the user sitting in the seat 5. Therefore, the user can determine the coverage area of ​​the outdoor working component and the degree of overlap with the already worked area by observing the position of the boundary of the worked area relative to the outer contour of the passive wheel 8 in their field of vision. This avoids leaving any unfinished work areas on the ground after the work has been completed.

[0112] In some optional embodiments, when looking forward from the top center of the backrest towards the vehicle, the passive wheel 8 is partially obscured by the display assembly 3 and is therefore invisible. That is, for the user sitting in the seat 5, the position of the boundary of the already worked area relative to the outer contour of the display assembly 3 in their field of vision can be used to determine the coverage area of ​​the outdoor working component and the degree of overlap with the already worked area, thereby avoiding any missed work areas on the ground after the work is completed. During this process, when judging the work area, the user can see the information displayed on the display assembly 3 in their peripheral vision. If the information displayed on the display assembly 3 changes significantly, it will be easily noticed by the user, allowing the user to obtain vehicle status information from the display assembly 3 in a timely manner and reducing the danger caused by not receiving timely warning information from the display assembly 3.

[0113] In other words, when a user looks at the display component 3 to obtain the vehicle status information displayed therein, their peripheral vision can also show the position of the boundary of the already-operated area relative to the outer contour of the display component 3 in their field of vision, thus allowing them to determine the coverage area of ​​the outdoor working component and the degree of overlap with the already-operated area. Alternatively, when a user looks at the display component 3 to obtain the vehicle status information displayed therein, they only need to adjust their gaze to see the position of the boundary of the already-operated area relative to the outer contour of the display component 3 in their field of vision, without having to turn their head. This reduces the time required for changing their gaze, allowing the user to concentrate more on driving the vehicle and improving operational safety.

[0114] In some optional embodiments, reference is made to the appendix. Figure 6 The side cover 2 comprises a lower cover 201, a rising part 202, and an upper cover 203 sequentially from front to rear in the vehicle. The upper cover 203 is higher than the lower cover 201. The display screen assembly 3 is mounted on the lower cover 201. That is, the display screen assembly 3 is located on the front side of the side cover 2, so that it is at a relatively obvious distance from the user in the first direction (the front-rear direction of the vehicle). In this embodiment, increasing the distance in the front-rear direction can reduce the angle between the display screen and the line connecting the user's eyes and the horizontal direction, that is, avoid the user having to look down significantly to see or see the display screen clearly.

[0115] In some optional embodiments, the multi-functional work vehicle further includes drive wheels 7 and an active steering assembly. The drive wheels 7 are disposed on the frame 1 and are driven by a power source disposed on the frame 1 to rotate as drive wheels, thereby propelling the vehicle. The active steering assembly is rotatably connected to the left and / or right side of the frame 1 to create a speed difference between the two drive wheels 7, thereby steering the vehicle; that is, the active steering assembly can be controlled by the user to steer the vehicle. The power source can be an internal combustion engine or an electric motor. Although their working principles differ, both can output torque to the tires to drive the vehicle. Internal combustion engines and electric motors are common existing technologies and will not be elaborated upon here.

[0116] In some optional embodiments, the display assembly 3 includes a display unit 31 and a display housing 32. When powered on, the display unit 31 can display patterns or characters to show vehicle information to the user; the display housing 32 at least partially covers the display unit 31 to secure it.

[0117] In some optional embodiments, at least one of the active steering components extends through the display assembly 3, and the display unit 31 for displaying patterns or character information is located in front of the active steering component.

[0118] In some optional embodiments, the multi-functional work vehicle includes an active steering component. When the user controls the active steering component to move forward, backward, left, or right, the vehicle moves in the corresponding direction. The corresponding multi-functional work vehicle includes a display screen component 3, through which the active steering component passes. That is, the display screen component 3 is relatively close to the active steering component, so when the user looks at either the display screen component 3 or the active steering component, they can clearly see the other in their peripheral vision. This reduces the amount of head or eye movement required when driving, lowers the difficulty of driving, and indirectly improves the vehicle's driving safety performance.

[0119] In one optional embodiment, the multi-functional work vehicle includes two active steering components, each used to control the rotation of a corresponding drive wheel 7, as shown in the attached figure. Figure 1 Appendix Figure 2 The control lever 4 shown in the figure is the active steering component, and the two control levers 4 are located on the left and right sides of the vehicle, respectively.

[0120] In one more specific embodiment, the multi-functional work vehicle includes two display screen assemblies 3 located on the left and right sides of the vehicle, respectively. Specifically, the two display screen assemblies 3 are located on the side covers 2 on the left and right sides of the vehicle, respectively. The two display screen assemblies 3 are used to display different vehicle information, such as: one display screen assembly 3 displays the vehicle's speed, remaining battery power (or fuel level), tire pressure, and temperature; the other display screen assembly 3 displays information such as the load level of outdoor work components. Two active steering components extend through the display screen assemblies 3 on both sides.

[0121] In some more specific embodiments, reference is made to the appendix. Figure 1 The multi-functional work vehicle includes a display screen assembly 3, with an active steering component extending through the display screen assembly 3. Users can access the information displayed on the display screen assembly 3 simply by looking to one side.

[0122] As described above, the multi-functional work vehicle includes two active steering components, and the active steering components control the speed change of the corresponding drive wheels 7 when moving forward and backward. In a more specific embodiment, refer to the attached... Figure 3 Appendix Figure 4 Appendix Figure 5The display assembly 3 has a steering hole 33 through which the corresponding active steering component passes. The display assembly 3 includes a display section and a connecting section, with the steering hole 33 disposed in the connecting section. The display assembly 3 is close to the corresponding active steering component, making it easier for the user to see the information displayed on the display assembly 3 when looking at the active steering component.

[0123] In one more specific embodiment, the forward movement of the active steering component controls the corresponding drive wheel 7 to rotate forward, and the backward movement of the active steering component controls the corresponding drive wheel 7 to rotate backward. The greater the movement of the active steering component, the faster the corresponding drive wheel 7 rotates. When the rotational speeds of the drive wheels 7 on both sides are unequal, the vehicle will steer. Therefore, the two active steering components control the vehicle's forward and backward movement and turning by their movement.

[0124] In some more specific embodiments, the active steering component can also move in the left and right directions. Specifically, after the right active steering component moves to the right, it can no longer move in the forward and backward directions, and after the left active steering component moves to the left, it can no longer move in the forward and backward directions. Furthermore, the right active steering component moving to the right or the left active steering component moving to the left will cause the vehicle to enter a parking state. The vehicle in the parking state needs to be unlocked before the drive wheels 7 can be controlled to rotate.

[0125] In some more specific embodiments, reference is made to the appendix. Figure 5 Appendix Figure 7 The steering hole 33 shown in the figure has a T-shaped structure, which means that the active steering component does not interfere with the side wall of the steering hole 33 when it moves forward, backward or to the right.

[0126] In some more specific embodiments, reference is made to the appendix. Figure 1 Appendix Figure 6 The upper cover 203 is at least partially located directly above the drive wheel 7, and the upper cover 203 is provided with a storage box 204 for the user to store personal items.

[0127] In some more specific embodiments, reference is made to the appendix. Figure 6 The rising part 202 is provided with a height adjustment groove 205, through which a height adjustment rod 10 is rotatably connected to the frame 1. When the height adjustment rod 10 rotates, it drives the outdoor working component to change its ground clearance. The height adjustment rod 10, the active steering component, and the display screen component 3 are all relatively commonly used components by the user, and their arrangement on the same side of the vehicle makes it easier for the user to operate the vehicle.

[0128] In some more specific embodiments, for precise assembly of the display assembly 3, refer to the attached drawing. Figure 6The lower cover 201 has a mounting surface 206, and the display assembly 3 has a first surface 37 that abuts against the mounting surface 206. That is, the lower cover and the display assembly 3 are in surface contact, and it has a relatively large contact area. When the vehicle is bumpy, the pressure of the display assembly 3 and the lower cover can be relatively dispersed to various parts of the contact surface, avoiding stress concentration and assembly failure.

[0129] In some embodiments, in order to make the connection between the display assembly 3 and the side cover 2 more stable, the display assembly 3 in this disclosure has at least two surfaces that abut against the side cover 2, and in order to make the abutment between the side cover 2 and the display assembly 3 more secure, a reinforcing rib is provided at one of the abutment surfaces of the side cover 2 and the display assembly 3. The reinforcing rib is perpendicular to the abutment surface or maintains a nearly perpendicular positional relationship with the abutment surface to enhance the strength of the abutment and avoid the risk of breakage due to excessive force at the abutment.

[0130] In some more specific embodiments, reference is made to the appendix. Figure 7 Appendix Figure 8 The display assembly 3 has a second surface 38 that is distinct from the first surface 37; see attached figure. Figure 9 The lower cover portion 201 has a limiting hole 207 through which the display assembly 3 passes. The second surface 38 abuts against one side of the inner wall of the limiting hole 207, and a reinforcing rib is provided on the inner wall of the side of the limiting hole 207 that abuts against the second surface 38. The first surface 37 and the second surface 38 are located on opposite sides of the display assembly 3. The first surface 37 shown in the figure is located on the lower side of the display assembly 3, and the second surface 38 is located on the upper side of the display assembly 3. The reinforcing rib at the limiting hole 207 extends at least partially along the extending direction of the inner wall of the limiting hole 207. This is used to improve the strength of the inner wall corresponding to the limiting hole 207 and avoid the risk of breakage due to concentrated stress on the inner wall.

[0131] In some more specific embodiments, reference is made to the appendix. Figure 7 Appendix Figure 8 Appendix Figure 9The side cover 2 has a mounting surface 206 and a limiting hole 207. The display screen assembly 3 has a first surface 37 and a second surface 38. The first surface 37 abuts against the mounting surface 206, and the second surface 38 abuts against one inner wall of the limiting hole 207. The inner wall of the limiting hole 207 abutting against the second surface 38 is provided with reinforcing ribs. In some specific embodiments, the display screen assembly 3 is partially inserted into the limiting hole 207. One inner wall of the limiting hole 207 is coplanar with the mounting surface 206, and the other inner wall of the limiting hole 207 is opposite to the mounting surface 206 and abuts against the display screen assembly 3. The inner wall of the limiting hole 207 opposite to the mounting surface 206 is provided with reinforcing ribs.

[0132] In some optional embodiments, at least two inner walls of the limiting hole 207 abut against the display assembly 3. One inner wall is flush with the aforementioned mounting surface 206, which has a larger area and can withstand a relatively large abutment force. The other inner wall has a smaller area, so a reinforcing rib is provided to improve the strength of the corresponding position and prevent the display assembly 3 from exerting too much pressure on the position during vehicle operation, which would cause damage to the limiting hole 207. In other words, it ensures that the display assembly 3 can be stably and effectively connected to the side cover 2.

[0133] As described above, the reinforcing rib at the limiting hole 207 extends at least partially along the extending direction of the inner wall of the limiting hole 207 (see attached figure). Figure 10 Appendix Figure 11 , attached Figure 10 This is a structural schematic diagram of side cover 2, attached. Figure 11 For the appendix Figure 10 The enlarged view shows that the reinforcing ribs include intersecting longitudinal ribs 209 and transverse ribs 208. Both longitudinal ribs 209 and transverse ribs 208 are thin plate-like structures. Together, they form a grid-like reinforcing rib, which increases the strength of the side wall of the limiting hole 207 and ensures the reliability of the connection between the display assembly 3 and the side cover 2.

[0134] In some optional embodiments, the first surface 37 of the display assembly 3 abuts against the mounting surface 206, and the second surface 38 of the display assembly 3 abuts against the wall of the limiting hole 207 with reinforcing ribs, thereby achieving initial fixation of the display assembly 3.

[0135] In some optional embodiments, one of the mounting surface 206 and the first surface 37 is provided with a protrusion 210, and the other of the mounting surface 206 and the first surface 37 is provided with a recess 39. The protrusion 210 and the recess 39 cooperate to enhance the connection strength between them. Specifically, in some optional embodiments, refer to the attached... Figure 8 Appendix Figure 9The mounting surface 206 is provided with an upward protrusion 210, and the first surface 37 is provided with a recess 39 that mates with the protrusion 210.

[0136] To secure the display assembly 3 to the side cover 2, locking devices are used to limit their position. In some optional embodiments, refer to the attached diagram. Figure 4 The protrusion 210 and the recess 39 are both permeated by a vertically extending locking bolt 310. It should be noted that the locking bolt 310 can be any type of bolt capable of locking, and does not refer to a specific bolt model. Since the protrusion 210 and the recess 39 are partial structures protruding from a plane, their sidewalls are perpendicular to the corresponding surface. This results in the structural strength of the protrusion 210 and the recess 39 being greater than that of other locations on the corresponding surface. In other words, a reinforcing rib effect is created at the connection between the protrusion 210, the recess 39, and the corresponding surface, allowing the first surface 37 or the mounting surface 206 to withstand a larger tightening force of the locking bolt 310 without damage. (See attached diagram.) Figure 4 Appendix Figure 8 The figure shows that the protrusion 210 and the recess 39 are jointly equipped with two locking bolts 310. Because the protrusion 210 and the recess 39 can withstand greater forces, the display assembly 3 and the side cover 2 do not need to be equipped with a relatively evenly distributed number of bolts, thus reducing assembly difficulty. It should be further noted that the protrusion 210 and the recess 39 can withstand greater fastening forces by enhancing the strength of their corresponding positions, thereby reducing the number of fastening bolts. However, a significant increase in the number of locking bolts 310 due to other assembly requirements should not be construed as exceeding the scope of protection of this embodiment.

[0137] In some optional embodiments, the mounting surface 206 has an upwardly projecting protrusion 210, and correspondingly, the first surface 37 has a recess 39 that mates with the protrusion 210. (See attached figure) Figure 11 To further increase the strength of the protrusion 210, a reinforcing rib, designated as protrusion rib 211, is provided on the lower wall of the protrusion 210. Correspondingly, to increase the strength of the recess 39, refer to the attached drawing. Figure 13 The figure shows a schematic diagram of the structure of the second shell 322. A reinforcing rib is also provided on the upper wall of the recess 39, which is marked as recess rib 311.

[0138] In some optional embodiments, reference is made to the appendix. Figure 12 The display assembly 3 includes a display unit 31 and a display housing 32 that covers at least a portion of the display unit 31. The display housing 32 includes a first housing 321 and a second housing 322, with the first housing 321 located above the second housing 322. (See attached diagram.) Figure 4The locking bolt 310 passes through the first housing 321, the second housing 322, and the side cover 2 from top to bottom and connects to the frame 1. The hole in the first housing 321 through which the locking bolt 310 passes is configured as a stepped hole, and the stepped hole extends downward to form a support tube 312 that abuts against the side cover 2. (See attached diagram) Figure 14 The figure shows a schematic diagram of the structure of the first housing 321 and the display unit 31. The fastening bolts directly limit the distance between the frame 1 and the first housing 321, thereby fastening the display assembly 3 to the side cover 2.

[0139] Reference Appendix Figure 15 Appendix Figure 16 Appendix Figure 17 , attached Figure 15 This is a side view of the first housing 321 and the display unit 31, with appended... Figure 16 For the appendix Figure 15 A cross-sectional diagram showing the viewpoint is attached. Figure 17 For the appendix Figure 16 The enlarged view shows that the support tube 312 extends downward through the second housing 322 and directly abuts against the side cover 2, which can prevent the locking bolt 310 from being rotated too much during assembly, causing deformation of the first housing 321 and reducing its strength. In addition, the support tube 312 is formed by extending downward through a stepped hole. Water above the first housing 321 may flow downward through the stepped hole. Its configuration of penetrating through the second housing 322 prevents water above from flowing into the display housing 32 through the stepped hole, reducing the possibility of water entering the display housing 32.

[0140] In some optional embodiments, to further increase the strength of the first housing 321 at the fastening bolts, reference is made to the appendix. Figure 14 Appendix Figure 17 The lower wall of the first housing 321 is provided with reinforcing ribs connected to the support tube 312. The reinforcing ribs at the support tube 312 include annular ribs 313 and radial ribs 314. The support tube 312 is located within the annular space of the annular ribs 313, and the radial ribs 314 connect the support tube 312 and the annular ribs 313 radially. When the stepped hole is compressed and deformed downward by the fastening bolts, the support tube 312 tends to deform. However, the radial ribs 314 and the annular ribs 313 exert a tensile force on the support tube 312, thereby reducing the deformation of the support tube 312 and increasing its strength, which in turn increases the strength of the first housing 321 at the fastening bolts.

[0141] As described above, the support tube 312 abuts against the upper wall of the side cover 2, that is, the support tube 312 abuts against the upper wall of the protrusion 210. In some optional embodiments, refer to the attached drawing. Figure 17The upper wall of the second housing 322 is provided with a protruding ring 315 that abuts against the annular rib 313. That is, the protruding ring 315 located in the second housing 322 generates abutting force against the annular rib 313 located in the first housing 321. When the locking bolt 310 acts on the support tube 312 and generates stress on the annular rib 313, the abutting force between the protruding ring 315 and the annular rib 313 can reduce the deformation of the annular rib 313, that is, further improve the strength of the first housing 321 at the fastening bolt.

[0142] In some optional embodiments, the upper wall of the convex ring 315 is higher than the lower end of the support tube 312. As mentioned above, water above the first housing 321 may flow downwards along the stepped hole. The fact that the upper wall of the convex ring 315 is higher than the lower end of the support tube 312 indicates a height difference between them. Rainwater can only enter the display housing 32 through the convex ring 315 if water accumulates in the protrusion 210 and the water level is higher than the convex ring 315. However, the gap between the support tube 312 and the fastening bolt is significantly small and a large amount of water will not flow in a short time. That is, rainwater will not enter the display housing 32 through the convex ring 315, thus reducing the overall possibility of water entering the display housing 32.

[0143] In some optional embodiments, reference is made to the appendix. Figure 7 The display screen assembly 3 is also equipped with a switch assembly, specifically a switch assembly located at the connection point of the display screen assembly 3. This switch assembly includes a vehicle switch 34 and / or a work component control switch 35. The vehicle switch 34 controls whether the multi-functional work vehicle is powered on. When the user starts driving the vehicle, they should operate the vehicle switch 34 to power on the vehicle, and then control the vehicle's operation through components such as the active steering assembly. The work component control switch 35 controls the activation or deactivation of the outdoor work component when the vehicle is powered on. After the vehicle has reached the work area, the outdoor work component can be activated or deactivated via the work component control switch 35 to enable work in the designated work area.

[0144] Reference Appendix Figure 6 The mounting surface 206 of the side cover 2 has a wire hole 212. The display screen assembly is equipped with a switch assembly for controlling the vehicle status. The switch assembly is connected to a wire that extends downward and passes through the wire hole 212. The wire passes downward through the wire hole 212 to the side cover 2 and is connected to the vehicle controller along the frame 1.

[0145] The switch assembly is located on the side of the steering hole 33 closer to the vehicle interior. As mentioned earlier, an active steering assembly is disposed within the steering hole 33. Since the active steering assembly is a component with a significantly higher frequency of operation than the switch assembly, its gripping portion is significantly higher than the side cover 2 to prevent accidental activation of the switch assembly when operating the active steering assembly. Furthermore, because the active steering assembly is significantly higher than the side cover 2, in some optional embodiments, the switch assembly is located on the side of the steering hole 33 closer to the vehicle interior in the left-right direction of the vehicle.

[0146] In other words, in the embodiment where the display assembly 3 is located on the right side of the vehicle, the switch assembly is located on the left side of the steering hole 33. In the embodiment where the display assembly 3 is located on the left side of the vehicle, the switch assembly is located on the right side of the steering hole 33.

[0147] In some optional embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 The active steering component is a lever 4 that passes through the steering hole 33 of the display panel and bends toward the center of the vehicle. It may also deflect outwards. In this embodiment, the switch component is positioned on the left side of the steering hole 33 to avoid interference with the switch component when the lever 4 deflects outwards.

[0148] In some optional embodiments, in order to facilitate user interaction with the vehicle's control system through the display component 3, the display unit 31 of the display component 3 is configured with buttons for user operation. The user can adjust the content displayed on the display unit 31 or send commands to the vehicle through the buttons.

[0149] In some optional embodiments, water should not enter the display unit 31, while physical buttons are prone to gaps in the display unit 31. Therefore, a waterproof component is required at the button to prevent water from seeping into the display unit 31 through the gaps in the physical button. (See attached figure.) Figure 19 The button on the display unit 31 in the figure is labeled "Key Body 3111".

[0150] In some optional embodiments, reference is made to the appendix. Figure 18 The figure shows a schematic diagram of the first housing 321. The first housing 321 is provided with a keyhole 3211 for a button to pass through. A flexible sealing element 3112 is provided at the keyhole 3211. The first housing 321 and the display unit 31 together compress the sealing element 3112 to form a sealed space that encloses the button, preventing external water from entering the display unit 31 through gaps. This ensures that the display assembly can maintain normal operation in rainy environments, and the vehicle can be equipped with the display assembly of this embodiment and operate normally in rainy environments.

[0151] To reduce weight and save material costs, the first housing 321 is generally made of plastic and is fixed to the display unit 31 by bolts. In some embodiments, to enhance the interaction between the user and the vehicle via buttons, two or more buttons are generally configured, each with a keyhole 3211 and a seal 3112. For a smaller display unit 31, the bolts at the edges can still effectively maintain the sealing effect of the seal 3112. However, for a larger display unit 31, the plastic first housing 321 may not maintain sufficient rigidity at its center, resulting in a slightly weaker compression force between it and the seal 3112, which may not effectively achieve the sealing effect.

[0152] Therefore, in some optional embodiments, reference is made to the appendix. Figure 18 The display unit 31 is provided with at least two buttons at intervals. The first housing 321 is provided with at least two keyholes 3211. A bolt is provided between at least two of the keyholes 3211 of the first housing 321. The bolt here mainly serves a sealing effect. To distinguish it from bolts in other positions, the bolt here is referred to as "sealing bolt 3113". This name is only based on the function of the bolt and does not necessarily refer to a specific type of bolt. That is, in this embodiment, any bolt that can effectively fasten the first housing 321 and the display unit 31 and compress the sealing element 3112 can be used.

[0153] The sealing bolt 3113 connects the first housing 321 and the display unit 31, and compresses the sealing member 3112. The sealing bolt 3113, together with the bolt that mates with the first housing 321 at the edge of the display unit 31, works together to achieve a sealing effect at the sealing member 3112. Specifically, the presence of the sealing bolt 3113 increases the rigidity of the first housing 321 at the sealing member 3112, thereby enabling the first housing 321 to make a tight contact with the display housing 32, thus ensuring an effective seal between the sealing member 3112 and the display housing 32, creating an effective sealing space and achieving a waterproof effect.

[0154] In some optional embodiments, reference is made to the appendix. Figure 18The first housing 321 in the figure is linearly arranged with five keyholes 3211 and four sealing holes 3212. A sealing bolt 3113 passes through the sealing holes 3212 and is threaded to the display unit 31. Two of the sealing holes 3212 are located between two of the keyholes 3211. Specifically, the five keyholes 3211 and four sealing holes 3212 are arranged linearly in the following order: first sealing hole 3212, first keyhole 3211, second keyhole 3211, second sealing hole 3212, third keyhole 3211, third sealing hole 3212, fourth keyhole 3211, fifth keyhole 3211, and fourth sealing hole 3212. In other embodiments, the number of keyholes 3211 can be freely adjusted according to the required number of buttons. However, in order for the seal 3112 to effectively seal the button, at least one sealing hole 3212 must be located between the two keyholes 3211. This ensures that after the large-area first housing 321 and the display unit 31 are fitted together, the seal 3112 at the keyhole 3211 can effectively seal the button.

[0155] In another optional embodiment, the first housing 321 does not have the aforementioned sealing hole 3212. Instead, a through hole is provided in the display unit 31, and an internal thread is provided in the first housing 321. The sealing bolt 3113 passes through the through hole of the display unit 31 and is threaded to the internal thread of the first housing 321, thereby compressing the sealing element 3112 to achieve a sealing effect. In this embodiment, the sealing bolt 3113 is not directly exposed to the outside, which not only makes the outer shell of the first housing 321 look simpler, but also avoids the sealing bolt 3113 from contacting rainwater and causing corrosion.

[0156] In some optional embodiments, reference is made to the appendix. Figure 7 Appendix Figure 20 The display unit 31 further includes an inclined screen, and the display housing 32 is provided with a screen hole for exposing the screen. In some embodiments, the lower edge 3213 of the connection between the display unit 31 and the screen hole is difficult to keep completely sealed, meaning that water seepage may occur at this connection. Therefore, a guide groove 3114 is provided on the lower side of the outer wall of the screen in the display unit 31. Rainwater flows into the display housing 32 through the gap between the screen hole and the display unit 31, and then flows to the bottom of the second housing 322 through the guide groove 3114. (See attached diagram) Figure 13 The bottom of the second housing 322 is provided with a drain hole 3221 so that water inside the second housing 322 can flow out. As shown in the figure, there are two drain holes 3221, which can ensure smooth drainage when one of the drain holes 3221 is blocked.

[0157] In some optional embodiments, the display unit 31 is configured with a touch screen that can be operated by the user, so the screen hole should be a through hole instead of a transparent glass layer that would affect touch operation.

[0158] In some optional embodiments, reference is made to the appendix. Figure 14 The display unit 31 has a signal line hole 36 on the side away from the first housing 321. A wire (not shown) for connecting the screen and the ride-on lawnmower passes through the signal line hole 36. The signal line hole 36 is coated with sealant (not shown).

[0159] In some optional embodiments, the multi-functional work vehicle further includes passive wheels 8 and a seat 5; wherein the passive wheels 8 are disposed at the front of the frame 1 on one side of the display assembly 3; for carrying the user; the passive wheels 8 are at least partially visible to the driver seated in the seat 5 without being obstructed by the display assembly 3. (See attached diagram) Figure 1 Appendix Figure 2 The multi-functional work vehicle shown in the figure includes two omnidirectional wheels, one of which is located at the front of the display assembly 3, which is the aforementioned passive wheel 8.

[0160] The passive wheel 8 is visible to the user without being obstructed by the display screen, allowing the user to judge the edge of the work area by the passive wheel 8 while driving and working, thus preventing omissions. Specifically, in some optional embodiments, the aforementioned outdoor working component is a cutting table 6 with a blade, and the multi-functional working vehicle is a lawnmower. When driving the lawnmower to mow the grass, the user needs to drive in a zigzag pattern, and during straight-line driving, generally control the current mowing area to have a small overlap with the already mowed area to avoid missing grass. Therefore, the user needs to know at all times whether the current mowing range meets expectations. In this embodiment, the passive wheel 8 is partially unobstructed and visible, and the user's line of sight when looking at the passive wheel 8 is at a similar height to the line of sight when looking at the display screen component 3. Therefore, the user can quickly switch between looking at the passive wheel 8 and looking at the display screen component 3; and when looking at the outline of the passive wheel 8, its outline can be compared with the already mowed area on the ground, allowing the user to know the relative positional relationship between the current mowing area and the already mowed area based on experience. If the current mowing area does not overlap with the already mowed area or the overlap is too large, the vehicle's orientation should be adjusted using the active steering component until there is a small overlap between the current mowing area and the already mowed area.

[0161] In other words, the display component 3 does not obstruct or completely obstruct the user's view of the passive wheel 8, allowing the user to judge whether the vehicle's position and angle are appropriate by the positional relationship between the passive wheel 8 and the mowed area. When looking at the passive wheel 8, the user can also clearly see the changes in the content of the display component 3 in their peripheral vision. If there are alarms or other information reminders on the display component 3, the user will be informed more promptly.

[0162] In some optional embodiments, in order for the user to clearly see the information of the display unit 31, the orientation of the display unit 31 needs to be relatively close to pointing towards the user's head. For ease of description and understanding, it is defined as follows: the first plane is parallel to the ground; the front-rear direction of the vehicle is the first direction; the second plane passes through the first direction and is perpendicular to the first plane.

[0163] For safety and comfort, the seat 5 includes a seat cushion and a backrest. The line connecting the top center of the seat 5 and the center of the display unit 31 is a first straight line. The angle between the projection of this first straight line onto the first plane and the first direction is less than or equal to 40°. (Refer to the attached diagram.) Figure 21 In the diagram, line a is the projection of the first line onto the first plane, and line b is parallel to the first direction, meaning the angle α between lines a and b is ≤ 40°; the angle between the projection of the first line onto the second plane and the first direction is less than or equal to 50°. (See attached diagram.) Figure 22 In the figure, line c is the projection of the first line onto the second plane, and line d is parallel to the first direction. Then the angle β between line c and line d is ≤ 50°.

[0164] The component of the entire vehicle closest to the user's head is the backrest of seat 5. Therefore, the line connecting the top center of seat 5 and the center of display unit 31 is relatively close to the user's line of sight. When the user is driving normally, their line of sight is mostly looking straight ahead in the first direction. Therefore, the angle between the projection of the first straight line in the first plane and the first direction, and the angle between the projection of the first straight line in the second plane and the first direction, can be used to describe the angle of deflection of the user's line of sight when they need to look at the display screen. Angles less than or equal to 40° and less than or equal to 50° indicate that the user needs to tilt their line of sight to see the display screen clearly.

[0165] In some optional embodiments, the angle between the projection of the first straight line onto the first plane and the first direction is greater than or equal to 20° and less than or equal to 40°. Furthermore, in some optional embodiments, the angle between the projection of the first straight line onto the second plane and the first direction is greater than 30° and less than or equal to 50°. This means the display screen is clearly located diagonally below the seat 5, preventing the display unit 31 from obstructing the view in front of the vehicle and affecting outdoor operations.

[0166] In some optional embodiments, a second straight line is defined as a straight line passing through the center of the display unit 31 and perpendicular to the plane of the display unit 31.

[0167] In some optional embodiments, the angle between the projection of the second straight line onto the first plane and the first direction is greater than or equal to 5° and less than or equal to 25°. (See attached diagram.) Figure 23 The figure shows a top view of the side cover 2. Line e is the projection of the second line in the first plane. Line f is parallel to the first line. The angle δ between line e and line f in the figure ranges from 25° to 5°. That is, the display unit 31 is tilted to the side of the seat 5 to a certain extent from the perspective of the top view.

[0168] The angle between the projection of the second straight line onto the second plane and the first direction is greater than or equal to 40° and less than or equal to 65°. (See attached document) Figure 24 The figure shows a side view of the side cover 2 part. The straight line g is the projection of the second straight line in the second plane. The straight line h is parallel to the first straight line. The angle ε between the straight line g and the straight line h in the figure ranges from 65°≥ε≥40°, which means that the display unit 31 is tilted upward to a certain extent in the side view.

[0169] The angles δ and ε mentioned above represent the orientation of the display unit 31, specifically the orientation of the screen portion on the display unit 31. This primarily affects whether it faces the user's face or the degree to which its orientation deviates from the user's face. In some optional embodiments, the angle between the projection of the second straight line onto the first plane and the first direction is greater than or equal to 10° and less than or equal to 20°, i.e., 20° ≥ δ ≥ 10°. Furthermore, in some optional embodiments, the angle between the projection of the second straight line onto the second plane and the first direction is greater than or equal to 50° and less than or equal to 60°, 60° ≥ ε ≥ 50°. Within this angle range, the user sitting in the seat 5 can see the information displayed by the display unit 31 relatively clearly.

[0170] In some optional embodiments, on the side of the display unit 31 near the seat 5, the position of the second straight line is higher than the position of the first straight line, that is, the display unit 31 is tilted towards the top or diagonally above the seat 5. Since the first and second straight lines have an intersection point located on the display unit 31, the first and second straight lines are coplanar and have an angle between them, which is greater than or equal to 15° and less than or equal to 50°. Because when sitting on the seat 5, the user's head is higher than the top of the seat 5, the tilt of the display unit 31 towards the top or diagonally above the seat 5 is closer to the user's eyes, making it easier for the user to clearly see the information on the display unit 31.

[0171] In some optional embodiments, the angle between the first straight line and the second straight line is greater than or equal to 20° and less than or equal to 30°. When the user sits in the seat 5, the user's eyes are within this angle range, allowing the user to see the information of the display unit 31 more clearly.

[0172] In some optional embodiments, the maximum viewing angle of the display unit 31 is 40° to 70°. That is, the content displayed by the display unit 31 can be effectively seen by any line of sight whose angle with the normal to the plane of the display unit 31 is less than the above-mentioned maximum viewing angle range.

[0173] In some optional embodiments, the distance between the top center of the seat 5 and the center of the display unit 31 in the first direction is 450mm to 750mm, that is, attached Figure 21 The value of X is 450mm to 750mm; in another more specific embodiment, the distance between the top center of the seat 5 and the center of the display unit 31 in the first direction is 550mm to 650mm. This range is consistent with the arm length of a normal adult, and the user can touch the display unit 31 by extending their arm or leaning forward slightly. That is, the above-mentioned distance range is significantly more ergonomic.

[0174] In some optional embodiments, this specification also discloses a multi-functional work vehicle, which includes a frame 1, a user platform, an outdoor work component, drive wheels 7, side covers 2, a display screen assembly 3, and an active steering assembly as described above. The frame 1 extends along a first direction, which is the longitudinal direction of the vehicle. The user platform is disposed on the frame 1 and is used to carry a user. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work. The drive wheels 7 are disposed on the left and right sides of the frame 1 and are used to drive the vehicle. The side covers 2 are disposed on the frame 1 and are located on the left and / or right side of the vehicle. The display screen assembly 3 is disposed in front of the side of the seat 5 and is used to display patterns or character information to the user. The active steering assembly is operably disposed on the frame 1 and is used to control the rotational speed of the drive wheels 7 on at least one side of the vehicle.

[0175] In some optional embodiments, the orthographic projections of the active steering component, display component 3, side cover 2, and frame 1 onto the ground at least partially overlap. That is, the horizontal spacing between the active steering component, display component 3, and side cover 2 is small. When the user looks at the active steering component, the content of the display screen can be seen in their peripheral vision, meaning the user can obtain vehicle status information promptly through the display unit 31 while operating the vehicle, thereby improving vehicle safety.

[0176] In some optional embodiments, the display assembly 3 is further configured with a switch assembly, that is, a switch assembly is configured at the connection part of the display assembly 3. The switch assembly includes a vehicle switch 34 and / or a work component control switch 35. The vehicle switch 34 is used to control whether the multi-functional work vehicle is in a powered-on state. When the user starts driving the vehicle, he should operate the vehicle switch 34 to power on the vehicle, and then control the vehicle to work through components such as the active steering component. The work component control switch 35 is used to control the start or stop of the outdoor work component when the vehicle is powered on. After the vehicle has traveled to the work site, the outdoor work component is controlled to start or stop through the work component control switch 35 to realize the work in the work area.

[0177] In some optional embodiments, the display assembly 3 includes a display element unit 31 and a display element housing 32 that at least partially encloses the display element. The active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 are located on the side closer to the rear of the vehicle relative to the display element unit 31. That is, the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 are located on the side closer to the user relative to the display element unit 31, thereby facilitating manual operation by the user. Because the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 are close to the display element unit 31, when the user is looking at and operating the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35, they can observe the content displayed on the display element unit 31 in their peripheral vision. In other words, the user can obtain vehicle status information in a timely manner through the display element unit 31 while operating the device, thereby improving vehicle safety.

[0178] In some optional embodiments, reference is made to the appendix. Figure 25The display unit 31 includes at least one button for user operation. At least one of these buttons is spaced 20mm to 100mm from the vehicle switch 34 or the operating component control switch 35 in a first direction, i.e., the range of Y in the figures is 20mm to 100mm. As described above, the close proximity of the display unit 31 to the vehicle switch 34 or the operating component control switch 35 facilitates the user's access to vehicle status information. However, when the user operates the vehicle switch 34 or the operating component control switch 35, the display unit 31 should not interfere with the user's hand; that is, the display unit 31 should not obstruct the user's hand from operating the vehicle switch 34 or the operating component control switch 35. The aforementioned distance of less than or equal to 100mm along the first direction satisfies the user's hand movement space. In some embodiments, the button of the display unit 31 and the vehicle switch 34 or the operating component control switch 35 are misaligned in the left-right direction of the vehicle. Therefore, appropriately shortening the distance between the button and the vehicle switch 34 or the operating component control switch 35 in the first direction will not cause interference. However, for ease of arrangement, the button still needs to be configured to have a distance of 20mm between it and the vehicle switch 34 or the working component control switch 35 in the first direction; in summary, at least one of the buttons is 20mm to 100mm apart from the vehicle switch 34 or the working component control switch 35 in the first direction.

[0179] In some optional embodiments, the user-supporting seat 5 includes a seat cushion and a backrest. The distance between at least one of the buttons and the top center of the backrest in a first direction is 420mm to 720mm. In another more specific embodiment, the distance between the top center of the seat 5 and at least one of the buttons in the first direction is 550mm to 650mm. This range corresponds to the arm length of a normal adult, allowing the user to operate the buttons by extending their arm or leaning slightly forward. In other words, the aforementioned distance range is significantly more ergonomic.

[0180] In some optional embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 The multi-functional work vehicle includes only one display screen assembly 3, with an active steering component running through it. Users can access the information displayed on the display screen assembly 3 simply by looking to one side.

[0181] As described above, the multi-functional work vehicle includes two active steering components, and the active steering components control the speed change of the corresponding drive wheels 7 when moving forward and backward. In a more specific embodiment, the display screen assembly 3 has a steering hole 33 through which the corresponding active steering component passes. The display screen assembly 3 includes a display part and a connecting part, and the steering hole 33 is disposed in the connecting part. The display screen assembly 3 is close to the corresponding active steering component, making it easier for the user to see the information displayed on the display screen assembly 3 when looking at the active steering component.

[0182] In one more specific embodiment, the forward movement of the active steering component controls the corresponding drive wheel 7 to rotate forward, and the backward movement of the active steering component controls the corresponding drive wheel 7 to rotate backward. The greater the movement of the active steering component, the faster the corresponding drive wheel 7 rotates. When the rotational speeds of the drive wheels 7 on both sides are unequal, the vehicle will steer. Therefore, the two active steering components control the vehicle's forward and backward movement and turning by their movement.

[0183] In some more specific embodiments, the active steering component can also move in the left-right direction, specifically, see attached... Figure 5 Appendix Figure 7 After the right-side active steering component moves to the right, it is limited by the steering hole 33 and cannot move forward or backward. After the left-side active steering component moves to the left, it cannot move forward or backward. Furthermore, the right-side active steering component moving to the right or the left-side active steering component moving to the left will cause the vehicle to enter the parking state. The vehicle in the parking state needs to be unlocked before the drive wheels 7 can be controlled to rotate.

[0184] In some optional embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 The display screen assembly 3 is located on the right side of the vehicle. The corresponding steering hole 33 is configured as a T-shaped hole (T-shaped horizontal) that can move to the right when the active steering assembly moves to the middle position in the forward and backward direction. That is, the active steering assembly does not interfere with the side wall of the steering hole 33 when it moves forward and backward or to the right.

[0185] In some more specific embodiments, when the active steering component moves to the right to put the vehicle into a parking state for a user on the user platform, the display unit 31 is visible without being obstructed by the active steering component. In the parking state, the wheels do not rotate, meaning the wheels are in a safe state. The display unit 31 should be freely controllable by the user in this state; therefore, the active steering component should not obstruct the display unit 31.

[0186] In some optional embodiments, when the active steering component moves to the left, allowing it to move back and forth along the steering hole 33, the display unit 31 is partially obscured by the active steering component and is not fully visible. This is because when the active steering component is in a non-parked state, allowing the vehicle to move back and forth along the steering hole 33, the vehicle may be moving and poses a certain danger. In this situation, the display unit 31 should only serve as a display component. Users should not remove their hands from the active steering component to touch the display unit 31; therefore, the active steering component is designed to obstruct the display unit 31. Even if the user releases their hand from the active steering component, it will inevitably be blocked by the active steering component, making it difficult to touch the display unit 31. In other words, the user is forced to operate the active steering component to the right to put the vehicle into a parking state; only when the vehicle is relatively safe can the user easily touch the display unit 31.

[0187] In some more specific embodiments, the display assembly 3 does not protrude significantly upwards from the highest point of the side cover 2. That is, the height of the display assembly 3 is approximately equal to or lower than that of the corresponding side cover 2. As mentioned above, the display unit 31 of the display assembly 3 protrudes forward from the side cover 2. The purpose of controlling the display assembly 3 not to protrude significantly upwards in this embodiment is to reduce the probability of it colliding with external objects. When an external object may collide laterally with the vehicle in this embodiment, the side cover 2 is more likely to bear the impact force, thus preventing damage to the display assembly 3 and avoiding greater economic losses due to damage to this relatively fragile component.

[0188] In some optional embodiments, reference is made to the appendix. Figure 1 Appendix Figure 6 The side cover 2 is equipped with a height adjustment groove 205, through which a height adjustment rod 10 is rotatably connected to the frame 1. When the height adjustment rod 10 rotates, it drives the change in the ground clearance of the outdoor working component to adapt to the actual needs of different users for outdoor operations. The height adjustment rod 10 is located on the side closer to the rear of the vehicle relative to the display screen assembly 3. Because the outdoor working component may be heavy, the height adjustment rod 10 being further back, i.e. closer to the user, makes it easier for the user to apply force to adjust the height of the outdoor working component.

[0189] In some optional embodiments, reference is made to the appendix. Figure 4 The vehicle frame 1 includes a main frame and a bridging component 101 fixed to the main frame. The bridging component 101 is a metal connector used to assist in the installation of the side cover 2, the display housing 32, etc., and can be regarded as part of the vehicle frame 1. Further, in this embodiment, the display housing 32, the side cover 2, and the bridging component 101 are all provided with steering holes 33 for the active steering assembly to pass through.

[0190] In some optional embodiments, the multi-functional work vehicle further includes a vehicle controller (not shown) for controlling the vehicle's operating status. The vehicle switch 34 and / or the work component control switch 35 are connected to the vehicle controller via wires. The side cover 2 has wire holes through which the vehicle switch 34 and / or the work component control switch 35 or the wires pass. (Refer to the attached drawing.) Figure 6 .

[0191] In some optional embodiments, reference is made to the appendix. Figure 7 The display housing 32 includes a connecting portion for configuring the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35, and a display portion extending in a direction different from the connecting portion; the display unit 31 is disposed on the display portion. The display portion is angled to the connecting portion so that the display unit 31 faces the user's head, thereby facilitating viewing by the user.

[0197] In some optional embodiments, the display unit 31 includes a user-operable button, allowing the user to interact with the display unit 31 via the button. The display housing 32 includes a first housing 321 and a second housing 322. The first housing 321 has at least two keyholes 3211 spaced apart for the button to pass through. A flexible sealing element 3112 is disposed at each keyhole 3211. A sealing hole 3212 is disposed between at least two of the keyholes 3211 of the first housing 321. The sealing hole 3212 is provided with a bolt for fastening the first housing 321 and the display unit 31 and pressing the sealing element 3112.

[0198] In another optional embodiment, this specification also discloses a multi-functional work vehicle, including a frame 1, a seat 5, an outdoor work component, a side cover 2, a display screen assembly 3, and a power system. The frame 1 extends along a first direction, which is the vehicle's longitudinal direction. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work. The side cover 2 is disposed on the left and / or right side of the frame 1. The display screen assembly 3 is disposed on the side cover 2 and is used to display patterns or character information to the user.

The display housing 32 at least covers a portion of the display unit 31 to provide protection and positioning for the display unit 31. The power system supplies power to the cutting table 6 and the display screen assembly 3.

[0199] In some optional embodiments, the display unit 31 includes a user-operable button, allowing the user to interact with the display unit 31 via the button. The display housing 32 includes a first housing 321 and a second housing 322. The first housing 321 has at least two keyholes 3211 spaced apart for the button to pass through. A flexible sealing element 3112 is disposed at each keyhole 3211. A sealing hole 3212 is disposed between at least two of the keyholes 3211 of the first housing 321. The sealing hole 3212 is provided with a bolt for fastening the first housing 321 and the display unit 31 and pressing the sealing element 3112.

[0200] In another optional embodiment, this specification also discloses a multi-functional work vehicle, which includes a frame 1, an outdoor work component, a side cover 2, and a display screen assembly 3 as described above. The frame 1 extends along a first direction, which is the front-to-back direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work. The side cover 2 is disposed on the left and / or right side of the frame 1. The display screen assembly 3 is disposed on the side cover 2 and is used to display pattern or character information to the user.

[0201] In some optional embodiments, reference is made to the appendix. Figure 3 The display housing 32 of the multi-functional work vehicle includes a nearly horizontal connection portion to the side cover 2 and a display portion extending in a different direction from the connection portion. The display screen assembly 3 includes a display unit 31 disposed on the display portion for displaying patterns or character information. That is, the display screen assembly 3 includes two portions extending in different directions, and the connection portion contacts the side cover 2 while remaining approximately horizontal. The display portion is tilted to face the user's face, avoiding the need for the user to significantly turn their head downwards to see the information on the display unit 31.

[0202] It should be noted that the aforementioned "nearly horizontal" of the connecting part should be understood as having a small angle with the horizontal direction. If the angle with the horizontal direction is within ±15°, it should be understood as being nearly horizontal. This is because within this angle range, it is not obvious to the naked eye that it is not horizontal.

[0203] In some optional embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 The multi-functional work vehicle also includes a user platform for carrying users. The normal of the plane on which the display unit 31 displays the pattern points directly above the user platform. The user is carried on the user platform, that is, the user's head is approximately directly above the user platform. The plane on which the display unit 31 displays the pattern is also the surface on which the screen of the display unit 31 is located. Therefore, the vertical line of the surface on which the screen of the display unit 31 is located points directly above the user platform, making it easy for the user to clearly see the information displayed by the display unit 31.

[0204] In another optional embodiment, refer to the appendix. Figure 1 Appendix Figure 2 The paper also discloses a multi-functional work vehicle, which includes a frame 1, an outdoor work component, a side cover 2, and a display screen assembly 3. The frame 1 extends along a first direction, which is the front-to-back direction of the vehicle. The outdoor work component is disposed on the frame 1 and is used to perform outdoor work. The side cover 2 is disposed on the frame 1 and is located on the left and / or right side of the vehicle. The display screen assembly 3 is disposed on the side cover 2 and is used to display pattern or character information to the user.

[0205] In some optional embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2The display assembly 3 includes a nearly horizontal connecting portion to the side cover 2 and a display portion extending in a direction different from the connecting portion. The display assembly 3 includes a display unit 31 disposed on the display portion for displaying patterns or character information. Specifically, the side cover 2 includes a nearly horizontal mounting surface 206, and the display assembly 3 includes a first surface 37 for mating with the mounting surface 206. The purpose of the nearly horizontal nature of the first surface 37 and the mounting surface 206 is that during the assembly process, when the display assembly 3 is placed on the mounting surface 206, the display assembly will not slide or shift due to its weight, thus facilitating assembly.

[0206] In this embodiment, the extension direction of the display unit differs from that of the connecting part. This is because the display unit is primarily used to display patterns or character information to the user via the display unit 31. As mentioned earlier, if the connecting part extends horizontally, its plane faces directly upwards. If the user looks at the connecting part, they need to tilt their head down so that their line of sight is vertically downwards to clearly see the characters on the surface of the connecting part. The extension direction of the display unit differs from that of the connecting part, meaning the display unit 31 is tilted relative to the horizontal plane. This allows the user to see the content displayed by the display unit 31 without having to tilt their head down significantly.

[0207] In some optional embodiments, the multi-functional work vehicle includes a user platform for carrying a user, and the normal to the plane displaying the pattern on the display unit 31 points directly above the user platform. When the user is carried on the user platform, the user's head is naturally positioned directly above the user platform. In this embodiment, the normal to the plane displaying the pattern on the display unit 31 is controlled to point directly above the user platform, that is, almost directly above the user's head, thereby facilitating the user's viewing of the patterns or character information displayed by the display unit 31. In some optional embodiments, the component of the display unit 31 used to display the pattern is a screen, and the plane displaying the pattern is the screen surface.

[0208] In some optional embodiments, the connection portion is equipped with a switch assembly, which includes a vehicle switch 34 and / or a work component control switch 35. The vehicle switch 34 controls whether the multi-functional work vehicle is powered on; the work component control switch 35 controls the start or stop of the outdoor work component when the vehicle is powered on. That is, both the switch assembly and the display unit 31 are located at the display screen assembly 3, allowing the user to conveniently operate the switch assembly while looking at the display unit 31. In other words, when the user operates the switch assembly to control the vehicle's status, they can conveniently look at the information displayed on the display unit 31 to confirm whether the vehicle status meets the user's expectations.

[0209] In some optional embodiments, the multi-functional work vehicle further includes drive wheels 7 and an active steering device; wherein the drive wheels 7 are disposed on the left and right sides of the frame 1 and are used to drive the vehicle; the active steering device is rotatably connected to the left and / or right sides of the frame 1 and is used to generate a speed difference between the drive wheels 7 on both sides to steer the vehicle.

[0210] In some optional embodiments, at least one of the active steering components passes through the connecting portion, and the display unit 31 is located in front of the active steering component, which can prevent the display unit 31 from affecting the operation of the active steering component.

[0211] In one of the optional embodiments, the display housing 32 has a steering hole 33 through which an active steering component passes. When the active steering component moves forward or backward within the steering hole 33 under the control of the user, it controls the rotational speed of at least one drive wheel 7. The steering hole 33 is configured as a T-shaped hole that can move to the left or right when the active steering component moves to the middle position in the front-back direction. That is, the active steering component does not interfere with the side wall of the steering hole 33 when it moves forward or backward or to the right.

[0212] In some more specific embodiments, when the active steering component moves to the right to put the vehicle into a parking state for a user on the user platform, the display unit 31 is visible without being obstructed by the active steering component. In the parking state, the wheels do not rotate, meaning the wheels are in a safe state. The display unit 31 should be freely controllable by the user in this state; therefore, the active steering component should not obstruct the display unit 31.

[0213] In some optional embodiments, the display unit 31 includes a touchscreen that can be touched by a user, allowing the user to input signals to the display unit 31 via touch in order to control the state of the vehicle.

[0214] In some optional embodiments, when the active steering component moves to the left, allowing it to move back and forth along the steering hole 33, the display unit 31 is partially obscured by the active steering component and is not fully visible. This is because when the active steering component is in a non-parked state, allowing the vehicle to move back and forth along the steering hole 33, the vehicle may be moving and poses a certain danger. In this situation, the display unit 31 should only serve as a display component. Users should not remove their hands from the active steering component to touch the display unit 31; therefore, the active steering component is designed to obstruct the display unit 31. Even if the user releases their hand from the active steering component, it will inevitably be blocked by the active steering component, making it difficult to touch the display unit 31. In other words, the user is forced to operate the active steering component to the right to put the vehicle into a parking state; only when the vehicle is relatively safe can the user easily touch the display unit 31.

[0215] In another optional embodiment, a ride-on lawnmower is also disclosed, comprising a frame 1, an outdoor working component, side covers 2, and a display assembly 3 as described above; wherein the frame 1 extends generally along a first direction, and the outdoor working component is configured as a cutter head 6 mounted to the frame 1 for performing mowing operations. The side covers 2 are disposed on the frame 1 and are located on the left and / or right side of the vehicle. The display assembly 3 is disposed on the side covers 2 and is used to display graphic or character information to a user. The display assembly 3 includes a connection portion that is nearly horizontally connected to the side covers 2 and a display portion that extends in a direction different from the connection portion. The display assembly 3 includes a display unit 31 disposed on the display portion for displaying graphic or character information.

[0216] In another optional embodiment, a ride-on lawnmower is also disclosed, comprising a frame 1, an outdoor working component, side covers 2, a power system, and a display assembly 3 as described above; wherein the frame 1 extends generally along a first direction, and the outdoor working component is configured as a cutter head 6 mounted to the frame 1 for performing mowing operations. The side covers 2 are disposed on the frame 1 and are located on the left and / or right side of the vehicle. The display assembly 3 is disposed on the side covers 2 and is used to display graphic or character information to a user. The power system supplies power to the outdoor working component and the display assembly 3. The display assembly 3 includes a connection portion that is nearly horizontally connected to the side covers 2 and a display portion that extends in a direction different from the connection portion; the display assembly 3 includes display unit 31 disposed on the display portion for displaying graphic or character information.

[0217] In another optional embodiment, a multi-functional work vehicle is also disclosed. The multi-functional work vehicle includes a frame 1, an outdoor work component, side covers 2, and a display screen assembly 3. The frame 1 extends along a first direction, which is the vehicle's longitudinal direction. The outdoor work component is disposed on the frame 1 and used to perform outdoor work. The side covers 2 are disposed on the frame 1 and located on the left and / or right side of the vehicle. The display screen assembly 3 is disposed on the side covers 2 and used to display patterns or character information to the user. The display screen assembly 3 includes components with an area of ​​not less than 80 cm². 2 The screen's relatively large size allows it to present more information to the user. Furthermore, the larger screen allows for larger icons and font sizes, making it easier for users to distinguish the information and improving usability. In addition, because the larger screen can display more information, users can obtain more information within a single interface, enabling them to make optimal decisions about outdoor operations. For example, users can simultaneously obtain information such as remaining battery range, remaining work area, time, or weather conditions for the next few hours, allowing them to decide whether to continue working.

[0218] In some optional embodiments, the screen area S of the display assembly 3 is greater than or equal to 100 cm². 2 In another optional embodiment, the screen area S of the display assembly 3 is greater than or equal to 120 cm². 2 As mentioned earlier, a larger screen can display more information; therefore, within the limits of space, a larger screen is more conducive to displaying information to the user. In some optional embodiments, the diagonal size of the display assembly 3 is greater than or equal to 6 inches. Further, in some optional embodiments, the screen size is 6.75 inches with an aspect ratio of 16:9, then the screen area is approximately 126 cm². 2 This better meets user needs. In another optional embodiment, the screen size is 8 or 10 inches with an aspect ratio of 16:9, wherein the 8-inch screen has an area of ​​approximately 176 cm². 2 The area of ​​a 10-inch screen is approximately 276 cm². 2 In other embodiments, the screen aspect ratio may be selected as 4:3 or 16:10, etc., which should not be construed as exceeding the protection scope of this embodiment, and will not be elaborated here.

[0219] In some optional embodiments, the display assembly 3 has a screen dot-per-inch (DPI) greater than or equal to 120, which refers to the number of sampled, displayable, or output dots per inch of length. In this embodiment, the screen outputs 120 × 120 = 14,400 pixels per square inch. Therefore, the higher the DPI, the clearer the displayed content. The display assembly 3 in this embodiment, with a DPI greater than or equal to 120, can meet the needs of most users.

[0220] In some optional embodiments, the multi-functional work vehicle further includes a seat 5, drive wheels 7, and an active steering device, wherein the seat 5 is disposed on the frame 1 and is used to carry a user; the drive wheels 7 are disposed on the left and right sides of the frame 1 and are used to drive the vehicle; the active steering device is rotatably connected to the left and / or right sides of the frame 1 and is used to generate a speed difference between the drive wheels 7 on both sides to steer the vehicle.

[0221] In some optional embodiments, the display assembly 3 includes a display unit 31 that displays patterns or character information when powered on, and a display housing 32 that covers at least a portion of the display unit 31. At least one of the active steering components passes through the display housing 32, and the display unit 31 is located in front of the active steering component, which can prevent the display unit 31 from affecting the operation of the active steering component.

[0222] In one of the optional embodiments, the display housing 32 has a steering hole 33 through which an active steering component passes. When the active steering component moves forward or backward within the steering hole 33 under the control of the user, it controls the rotational speed of at least one drive wheel 7. The steering hole 33 is configured as a T-shaped hole that can move to the left or right when the active steering component moves to the middle position in the front-back direction. That is, the active steering component does not interfere with the side wall of the steering hole 33 when it moves forward or backward or to the right.

[0223] In some optional embodiments, reference is made to the appendix. Figure 21 The distance X between the top center of the seat 5 and the center of the display unit 31 in the first direction is greater than or equal to 45cm and less than or equal to 75cm. In another more specific embodiment, the distance between the top center of the seat 5 and the center of the display unit 31 in the first direction is 55cm to 65cm. This range corresponds to the arm length of a normal adult, allowing the user to touch the display unit 31 by extending their arm or leaning slightly forward. In other words, the aforementioned distance range is significantly more ergonomic.

[0224] In some optional embodiments, the area S (cm²) of the screen 2The ratio of the distance to X (cm) is greater than or equal to 1.5 (cm) and less than or equal to 3 (cm). As mentioned earlier, if the screen area is 120cm²... 2 If the distance is 45cm, the corresponding ratio is 2.67; if the screen area is 100cm² 2 If the distance is 50cm, then the corresponding ratio is 2; if the screen area is 80cm² 2 If the distance is 50m, the corresponding ratio is 1.6. The above represent relatively comfortable viewing distances and screen sizes for users, without the screen being too large and obstructing their view.

[0225] In another alternative embodiment, this specification also discloses a ride-on lawnmower comprising a frame 1, an outdoor working component, side covers 2, and a display assembly 3 as described above; wherein the frame 1 extends generally along a first direction, and the outdoor working component is configured as a cutter head 6 mounted to the frame 1 for performing lawnmowing operations.

The display assembly 3 is disposed on the side covers 2 and is used to display graphic or character information to the user. The display assembly 3 includes an area S of not less than 80 cm². 2 The screen.

[0226] In another alternative embodiment, this specification also discloses a ride-on lawnmower comprising a frame 1, an outdoor working component, side covers 2, a power system, and a display assembly 3 as described above; wherein the frame 1 extends generally along a first direction, and the outdoor working component is configured as a cutter head 6 mounted to the frame 1 for performing lawnmowing operations. The side covers 2 are disposed on the frame 1 and are located on the left and / or right side of the vehicle. The display assembly 3 is disposed on the side covers 2 and is used to display graphic or character information to the user. The power system supplies power to the outdoor working component and the display assembly 3. The display assembly 3 includes a component with an area S not less than 80 cm². 2 The screen.

[0227] Furthermore, at least a portion of the aforementioned power system is detachably connected to the vehicle frame 1. The power system includes multiple battery units detachable from the vehicle frame 1. 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.

[0228] 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.

[0229] 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 can also be nickel-cadmium battery cells, lead-acid battery cells, graphene cells, etc.

[0230] The power system 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 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.

[0231] In one alternative embodiment, the power system further includes a battery compartment 9, a battery management system, etc., wherein the battery compartment 9 is used to house the battery pack, and the battery management system is used to manage the power supply of the battery pack to various components of the vehicle.

[0232] In one alternative embodiment, the battery compartment 9 and / or battery management system are configured on the frame 1, and the battery pack is detachably configured in the battery compartment 9 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; and the design of the detachable battery pack means that when the vehicle's power is low or depleted, there is no need to wait for a long charging time, and the vehicle can be quickly restored to a working state simply by replacing the battery pack.

[0233] In one alternative embodiment, the battery compartment 9 is detachably configured on the frame 1, and the battery is housed within the battery compartment 9, meaning that the battery compartment 9 can be completely separated from or combined with the frame 1.

[0234] In some optional embodiments, the outdoor working component is implemented as a cutting table 6, and the multi-functional working vehicle in this embodiment is a lawnmower; furthermore, if the outdoor working component is a snow sweeping component, then the multi-functional working vehicle is a snow sweeper; that is, the outdoor working component, as the main functional component of the multi-functional working vehicle, can be changed according to the user's selection; at the same time, in some embodiments, the above-mentioned outdoor working component can also be a component that the user can replace according to actual needs, such as removing the cutting table 6 used for mowing and replacing it with a sweeping disc used for sweeping, thus changing the lawnmower into a sweeper. In summary, replacing the outdoor working component with any functional component according to user needs should not be construed as exceeding the protection scope of this embodiment.

[0235] As mentioned earlier, a work vehicle equipped with a power system is a charging work vehicle. Compared with traditional fuel-powered work vehicles, charging work vehicles have the advantages of 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 the charging work vehicle uses an electric motor instead of a fuel engine, and the electric motors of the drive wheels 7 can be controlled separately to realize the vehicle's straight-line, reverse, turning, zero-steering and other motion control, which reduces the structural complexity of the vehicle and makes the control of the vehicle more flexible.

[0236] Similarly, garden vehicles equipped with a power supply system are called rechargeable garden vehicles, and they also have the aforementioned beneficial effects.

[0237] Referring to the accompanying drawings, the work vehicle shown is equipped with a steering lever. The user controls the vehicle by manipulating the steering lever to change the rotation speed of the drive wheel 7. In other embodiments, the steering lever can be changed to a steering wheel-type structure. That is, the method of vehicle steering should not be construed as breaking the protection scope of this embodiment.

[0238] 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.

[0239] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0240] This invention is not limited to the specific embodiments described above. Those skilled in the art will readily understand that many alternative solutions for the lawnmower and control handle of this invention can be found without departing from the principles and scope of the invention. The scope of protection of this invention is defined by the claims.
