They do not indicate or imply that the device referred to must have a specific direction or be constructed or operated in a specific direction. Therefore, they should not be construed as limiting the utility model.

[0073] Unless otherwise specified, the terms "disposed," "connected," and "connected" in this utility model should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can be directly connected or indirectly connected through an intermediary. "Fixed connection" in this utility model should also be broadly understood to mean integral molding, welding, or connection via other fasteners.

[0074] This embodiment discloses a multifunctional working vehicle. Figure 1 , including a frame 1, outdoor work components, and a seat 5; the frame 1 extends along a first direction, which is also the forward direction of the vehicle; the outdoor work components are arranged on the frame 1 and are used to perform outdoor work; the seat 5 is arranged on the frame 1 and is used to carry users.

[0075] In order to make the vehicle appearance more beautiful, it is generally also provided with a cover on the left side and / or right side and / or rear side of the vehicle. Figure 1 The multi-functional work vehicle includes a side cover 2. The side cover 2 shown in the figure is 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 text information to the user when powered on. In another optional embodiment, the side cover 2 equipped with a display screen can also be located on the left side of the vehicle. In another optional embodiment, side covers 2 are installed on both the left and right sides of the vehicle, and both sides are equipped with a display screen assembly 3 that can display patterns or text information to the user. It should be noted that to ensure a relatively stable position of the side cover 2 in the vehicle, it is fixed to the vehicle frame 1 using fasteners such as bolts.

[0076] In some optional embodiments, the seat 5 includes a seat cushion and a backrest, and the backrest is used for the user to lean on when sitting on the seat cushion. Looking toward the front of the vehicle along the top center of the backrest, the side front outer contour of the vehicle located in front of the display screen assembly 3 is visible. In this embodiment, the display screen assembly 3 capable of displaying pattern or character information to the user is configured on one side of the vehicle, and the side front outer contour on the side of the display screen is not blocked by the display screen assembly 3 and is in a visible state. In other words, it will not affect the user's ability to determine the positional relationship between the vehicle and ground objects by observing the side front outer contour of the vehicle, and there will be no situation where the driving route is incorrect due to the inability to determine the vehicle's positional relationship.

[0077] It should be noted that the top of the backrest of the seat 5 is the physical position closest to the user's head on the vehicle, so looking towards the front of the vehicle along the center of the top of the backrest is approximately the line of sight of the user sitting in the seat 5 looking towards the front of the vehicle. Figure 2 The front outer contour of the vehicle in front of the display assembly 3 is visible to the user sitting in the seat 5, that is, the user's line of sight can see the ground through the front outer contour of the vehicle. Figure 2 The shaded portion is the ground area visible to the user along the side front outer contour of the vehicle. The aforementioned side front outer contour of the vehicle is: the outer contour of the front of the vehicle viewed from the head of the user driving the vehicle.

[0078] When performing outdoor work on the ground, the work vehicle will first travel in a straight line. When it reaches the edge of the work area, it will turn around and travel in the opposite direction of the original direction. The outdoor work components will overlap slightly with the worked area to ensure that no work area is missed. In this embodiment, when the overlapping area is located on the side of the vehicle close to the display screen assembly 3, the display screen assembly 3 may block the edge of the outdoor work components. However, as mentioned above, the front outer contour of the wheel in front of the display screen assembly 3 is visible to the user sitting in the seat 5. For the same user, the coverage of the vehicle's outdoor work components relative to the user's view of the vehicle's outer contour remains unchanged. Therefore, the user can determine the degree of overlap between the coverage of the outdoor work components and the worked area by observing the positional relationship between the boundary of the worked area and the outer contour of the vehicle. In other words, the user determines the degree of overlap between the coverage of the outdoor work components and the worked area by the position of the boundary of the worked area relative to the outer contour of the vehicle in the field of view. This avoids missing areas to be worked on the ground after the work.

[0079] In some optional embodiments, the multifunctional working vehicle further includes a passive wheel 8 disposed at the front of the frame 1 on one side of the display screen assembly 3, as shown in FIG. Figure 1The multifunctional working vehicle shown in the figure includes two universal wheels located in the front of the vehicle, wherein the universal wheel located on the side of the display screen assembly 3 is the aforementioned passive wheel 8, and the passive wheel 8 is located at the component closest to the front edge of the vehicle.

[0080] In this embodiment, when looking toward the front of the vehicle from the center of the top of the backrest, at least a portion of the passive wheel 8 is not blocked by the display screen assembly 3 and is visible. In other words, at least a portion of the passive wheel 8 is visible to the user sitting in the seat 5. The user can then determine the degree of overlap between the coverage of the outdoor working components and the worked area by the position of the boundary of the worked area relative to the outer contour of the passive wheel 8 in the field of view. This avoids missing areas to be worked on the ground after the work.

[0081] In some optional embodiments, when looking toward the front of the vehicle along the top center of the backrest, a portion of the passive wheel 8 is blocked by the display screen assembly 3 and is not visible. That is, for a user sitting in the seat 5, the coverage of the outdoor working components and the degree of overlap with the worked area can be judged by the position of the boundary of the worked area relative to the outer contour of the display screen assembly 3 in the field of view, thereby avoiding the omission of the area to be worked on the ground after the work. In this process, when the user is judging the scope of the working area, the user can see the information displayed by the display screen assembly 3 with his peripheral vision. If the information displayed by the display screen assembly 3 changes significantly, it will be easily noticed by the user, thereby facilitating the user to obtain the vehicle status information from the display screen assembly 3 in a timely manner, reducing the danger caused by the failure to obtain the warning information of the display screen assembly 3 in a timely manner.

[0082] In other words, when the user looks at the display screen assembly 3 to obtain the vehicle status information displayed on the display screen assembly 3, the user can also see the position of the boundary of the operated area relative to the outer contour of the display screen assembly 3 in the field of view through the peripheral vision of the user's eye, thereby judging the degree of overlap between the coverage of the outdoor working components and the operated area. Alternatively, when the user looks at the display screen assembly 3 to obtain the vehicle status information displayed on the display screen assembly 3, the user only needs to adjust their gaze to see the position of the boundary of the operated area relative to the outer contour of the display screen assembly 3 in the field of view without having to turn their head. This reduces the time required to switch sight lines, allowing the user to focus more on driving the vehicle and improving operational safety.

[0083] In some optional embodiments, refer to the attached Figure 6The side cover 2 comprises, in order from the front to the rear of the vehicle, a lower cover portion 201, a rising portion 202, and an upper cover portion 203. The upper cover portion 203 is higher than the lower cover portion 201, and the display assembly 3 is mounted on the lower cover portion 201. Specifically, the display assembly 3 is located on the front side of the side cover 2, so that it is significantly distanced from the user in the first direction (the front-to-back direction of the vehicle). In this embodiment, increasing the distance in the front-to-back direction can reduce the angle between the display assembly and the user's eye level relative to the horizontal direction, thereby preventing the user from having to significantly lower their head to see or clearly understand the display.

[0084] In some optional embodiments, the multifunctional working vehicle further includes a driving wheel 7 and an active steering assembly. The driving wheel 7 is arranged on the frame 1, and is driven by a power source arranged on the frame 1 to rotate as an active wheel, thereby driving the vehicle to travel; the active steering assembly is operably rotatably connected to the left and / or right side of the frame 1, and is used to generate a speed difference between the driving wheels 7 on both sides to cause the vehicle to turn; that is, the active steering assembly can be controlled by the user to control the steering of the vehicle. The above-mentioned power source can be an internal combustion engine or an electric motor. Although there are differences in their working principles, both can output torque to the tires to drive the vehicle to travel, and power sources such as internal combustion engines and electric motors are common existing technologies and will not be described in detail here.

[0085] In some optional embodiments, the display screen assembly 3 includes a display unit 31 and a display housing 32. The display unit 31 can display images or text when powered on to present vehicle information to the user; the display housing 32 at least partially covers the display unit 31 to secure the display unit 31.

[0086] In some optional embodiments, at least one of the active steering components passes through the display screen component 3, and the display unit 31 of the display screen component 3 for displaying pattern or character information is located in front of the active steering component.

[0087] In some optional embodiments, the multifunctional work vehicle includes an active steering assembly. When a user manipulates the active steering assembly to move forward, backward, left, or right, the vehicle is controlled to move in the corresponding direction. The corresponding multifunctional work vehicle includes a display screen assembly 3. The active steering assembly extends through the display screen assembly 3. That is, the display screen assembly 3 is relatively close to the active steering assembly. When a user looks at either the display screen assembly 3 or the active steering assembly, the user can clearly see the other in their peripheral vision. This reduces the amount of head or eye movement when the user drives the vehicle, reduces the difficulty of driving operations, and indirectly improves the driving safety performance of the vehicle.

[0088] In some optional embodiments, the multifunctional working vehicle includes two active steering assemblies, and the two active steering assemblies are respectively used to control the rotation of the driving wheels 7 on the corresponding sides. Figure 1 , attached Figure 2 The joystick 4 shown in the figure is the active steering component, and the two joysticks 4 are respectively located on the left and right sides of the vehicle.

[0089] In some more specific embodiments, the multifunctional work vehicle includes two display screen assemblies 3 located on the left and right sides of the vehicle, i.e., the two display screen assemblies 3 are located on the left and right side covers 2 of the vehicle, respectively. The two display screen assemblies 3 are respectively used to display different vehicle information, such as: one display screen assembly 3 is used to display information such as the vehicle's speed, remaining battery (or fuel level), tire pressure, and temperature; the other display screen assembly 3 is used to display information such as the load level of outdoor work components. Two active steering assemblies extend through the display screen assemblies 3 on each side.

[0090] In some of the more specific embodiments, refer to the attached Figure 1 The multifunctional working vehicle includes a display screen assembly 3, wherein an active steering assembly passes through the display screen assembly 3. The user only needs to look to one side to obtain the information displayed by the display screen assembly 3.

[0091] As described above, the multifunctional working vehicle includes two active steering components, and the active steering components control the corresponding driving wheel 7 speed changes when moving forward and backward. Figure 3 , Attachment Figure 4 , Attachment Figure 5 The display screen assembly 3 is provided with a steering hole 33 for the corresponding active steering assembly to pass through. The display screen assembly 3 includes a display portion and a connection portion, with the steering hole 33 disposed in the connection portion. The display screen assembly 3 is relatively close to the corresponding active steering assembly, allowing the user to more easily see the information displayed on the display screen assembly 3 when looking at the active steering assembly.

[0092] In some more specific embodiments, forward movement of the active steering assembly controls the forward rotation of the corresponding drive wheel 7, while backward movement of the active steering assembly controls the backward rotation of the corresponding drive wheel 7. The greater the movement of the active steering assembly, the faster the speed of the corresponding drive wheel 7. When the speeds of the drive wheels 7 on both sides are unequal, the vehicle will turn. Thus, the two active steering assemblies control the forward and backward travel and turning of the vehicle through their respective movement amounts.

[0093] In some of the more specific embodiments, the active steering assembly can also move in the left and right directions. Specifically, after the right active steering assembly moves to the right, it can no longer move in the forward and backward directions, and after the left active steering assembly moves to the left, it can no longer move in the forward and backward directions; and the right active steering assembly moving to the right or the left active steering assembly moving to the left will cause the vehicle to enter a parking state. A vehicle entering the parking state needs to be unlocked before the drive wheel 7 can be controlled to rotate.

[0094] In some of the more specific embodiments, refer to the attached Figure 5 , Attachment Figure 7 The steering hole 33 shown in the figure is a T-shaped structure, that is, the active steering component does not interfere with the side wall of the steering hole 33 when moving forward, backward or rightward.

[0095] In some of the more specific embodiments, refer to the attached Figure 1 , Attachment Figure 6 The upper covering portion 203 is at least partially located directly above the driving wheel 7 , and the upper covering portion 203 is provided with a storage box 204 for users to store their belongings.

[0096] In some of the more specific embodiments, refer to the attached Figure 6 The rising portion 202 is provided with a height adjustment slot 205, through which a height adjustment lever 10 is operatively connected to the vehicle frame 1. Rotation of the height adjustment lever 10 drives the ground clearance of the outdoor operating components. The height adjustment lever 10, active steering assembly, and display assembly 3 are all relatively common components used by users. Their placement on the same side of the vehicle facilitates convenient vehicle control.

[0097] In some of the more specific embodiments, in order to accurately assemble the display screen assembly 3, refer to the attached Figure 6 The lower covering portion 201 has an assembly surface 206, and the display screen assembly 3 has a first surface 37 that abuts the assembly surface 206, that is, the lower covering portion and the display screen assembly 3 are in surface contact, which has a relatively large contact area. When the vehicle bumps, the extrusion force between the display screen assembly 3 and the lower covering portion can be dispersed at various locations on the contact surface by relative movement, thereby avoiding stress concentration and causing assembly failure.

[0098] In some of the embodiments, in order to make the connection between the display screen assembly 3 and the side cover 2 more stable, the display screen assembly 3 in the present 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 screen assembly 3 more firm, a reinforcing rib is provided at the abutment between the side cover 2 and one of the surfaces of the display screen assembly 3. The reinforcing rib is perpendicular to the abutment surface or maintains a position relationship close to perpendicular to the abutment surface, so as to enhance the strength of the abutment and avoid the risk of breakage due to large force on the abutment.

[0099] In some of the more specific embodiments, refer to the attached Figure 7 , Attachment Figure 8 The display screen assembly 3 has a second surface 38 different from the first surface 37; Figure 9 The lower covering portion 201 is provided with a limiting hole 207 that is penetrated by the display screen assembly 3. The second surface 38 abuts against one of the inner walls of the limiting hole 207. The inner wall of the side where the limiting hole 207 abuts against the second surface 38 is provided with a reinforcing rib. The first surface 37 and the second surface 38 are respectively located on opposite sides of the display screen assembly 3. The first surface 37 shown in the figure is located on the lower side of the display screen assembly 3, and the second surface 38 is located on the upper side of the display screen assembly 3. The reinforcing rib at the limiting hole 207 at least partially extends along the extension direction of the inner wall of the limiting hole 207. It is used to increase the strength of the inner wall corresponding to the limiting hole 207 to avoid the risk of the inner wall being broken due to the concentrated force.

[0100] In some of the more specific embodiments, refer to the attached Figure 7 , Attachment Figure 8 , Attachment Figure 9 The side cover 2 has a mounting surface 206 and a retaining hole 207. The display assembly 3 has a first surface 37 and a second surface 38. The first surface 37 abuts the mounting surface 206, and the second surface 38 abuts one inner wall of the retaining hole 207. The inner wall of the retaining hole 207 abutting the second surface 38 is provided with a reinforcing rib. In some specific embodiments, the display assembly 3 is partially inserted into the retaining hole 207. One inner wall of the retaining hole 207 is coplanar with the mounting surface 206, while the other inner wall of the retaining hole 207 faces the mounting surface 206 and abuts the display assembly 3. The inner wall of the retaining hole 207 facing the mounting surface 206 is provided with a reinforcing rib.

[0101] In some of the optional embodiments, at least two inner walls of the limiting hole 207 abut against the display screen assembly 3, one of the inner walls is flush with the aforementioned assembly surface 206, and the area of ​​the assembly surface 206 is larger and can withstand a relatively large abutting force, and the area of ​​the other inner wall is smaller. Therefore, reinforcing ribs are configured to achieve the purpose of improving the strength of the corresponding position, so as to prevent the display screen assembly 3 from exerting greater pressure on the position during the operation of the vehicle and causing damage to the limiting hole 207, that is, to ensure that the display screen assembly 3 can be stably and effectively connected to the side cover 2.

[0102] As mentioned above, the reinforcing rib at the limiting hole 207 at least partially extends along the extension direction of the inner wall of the limiting hole 207. Figure 10 , Attachment Figure 11 , attached Figure 10 is a schematic structural diagram of the side cover 2, Figure 11 For attachment Figure 10 A partial enlarged view shows that the reinforcing ribs in the figure include cross-arranged longitudinal ribs 209 and transverse ribs 208. The longitudinal ribs 209 and transverse ribs 208 are both thin plate structures. The longitudinal ribs 209 and transverse ribs 208 together 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.

[0103] In some optional embodiments, the first surface 37 of the display screen assembly 3 abuts against the assembly surface 206, and the second surface 38 of the display screen assembly 3 abuts against the wall of the limiting hole 207 with the reinforcing ribs, thereby achieving preliminary fixation of the display screen assembly 3.

[0104] In some optional embodiments, one of the assembly surface 206 and the first surface 37 is provided with a protrusion 210, and the other of the assembly surface 206 and the first surface 37 is provided with a recess 39. The protrusion 210 cooperates with the recess 39 to enhance the connection strength between the two. Figure 8 , Attachment Figure 9 The assembly surface 206 is provided with an upward protrusion 210 , and the first surface 37 is provided with a recessed portion 39 that cooperates with the protrusion 210 .

[0105] In order to fix the display screen assembly 3 to the side cover 2, the two need to be limited by a locking member. In some optional embodiments, refer to the attached Figure 4 , the protrusion 210 and the recess 39 are penetrated by a locking bolt 310 in the up and down directions. It should be noted that the locking bolt 310 here can be any bolt that can achieve locking, and does not refer to its specific bolt model. Since the protrusion 210 and the recess 39 are local structures protruding from the plane, the side walls of the protrusion are perpendicular to the corresponding surface, so that the structural strength of the protrusion 210 and the recess 39 is greater than that of other positions on the corresponding surface, that is, the connection between the protrusion 210, the recess 39 and the corresponding surface produces a technical effect of reinforcing ribs, so that the first surface 37 or the assembly surface 206 can bear the larger tightening force of the locking bolt 310 without damage. Refer to the attached Figure 4 , Attachment Figure 8The 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 bear a greater force, the display screen assembly 3 and the side cover 2 do not need to be relatively evenly equipped with a large number of bolts, thereby reducing the difficulty of assembly. It should be noted that the protrusion 210 and the recess 39 can withstand greater tightening force because they can enhance the strength of the corresponding positions, thereby reducing the number of tightening bolts. However, significantly increasing the number of locking bolts 310 due to other assembly requirements should not be construed as exceeding the scope of protection of this embodiment.

[0106] In some optional embodiments, the assembly surface 206 has an upwardly protruding portion 210, and correspondingly, the first surface 37 has a recessed portion 39 that cooperates with the protruding portion 210. Figure 11 In order to further increase the strength of the protrusion 210, a reinforcing rib is provided on the lower wall of the protrusion 210, which is marked as a protruding rib 211. Accordingly, in order to increase the strength of the recessed portion 39, refer to the attached Figure 13 , the figure shows a schematic structural diagram of the second shell 322 , in which a reinforcing rib is also provided on the upper wall of the recessed portion 39 , marked as a recessed rib 311 .

[0107] In some optional embodiments, refer to the attached Figure 12 The display screen assembly 3 includes a display unit 31 and a display housing 32 covering at least a portion of the display unit 31. The display housing 32 includes a first housing 321 and a second housing 322. The first housing 321 is located above the second housing 322. Figure 4 The locking bolt 310 passes through the first housing 321, the second housing 322, and the side cover 2 from top to bottom and is connected to the vehicle frame 1. The hole in the first housing 321 through which the locking bolt 310 passes is configured as a stepped hole, which extends downward to form a support tube 312 that abuts against the side cover 2. Figure 14 , the figure shows a schematic structural diagram of the first shell 321 and the display unit 31 , and the fastening bolts directly limit the distance between the frame 1 and the first shell 321 , thereby fastening the display assembly 3 to the side cover 2 .

[0108] Reference Attachment Figure 15 , Attachment Figure 16 , Attachment Figure 17 , attached Figure 15 is a side view of the first housing 321 and the display unit 31, Figure 16 For attachment Figure 15 Schematic diagram of the cutaway view shown, Figure 17 For attachment Figure 16As shown in the partially enlarged view, the support tube 312 passes downward through the second shell 322 and directly abuts against the side cover 2, which can prevent the locking bolt 310 from rotating excessively during assembly, thereby causing the first shell 321 to deform and reduce its strength. In addition, the support tube 312 is formed by extending the step hole downward. Water above the first shell 321 may flow downward along the step hole. The configuration of the support tube 312 passing through the second shell 322 prevents the water above from flowing into the display shell 32 through the step hole, thereby reducing the possibility of water entering the display shell 32.

[0109] In some optional embodiments, in order to further increase the strength of the first housing 321 at the fastening bolts, the following reference is made to the Figure 14 , Attachment Figure 17 The lower wall of the first shell 321 is equipped with reinforcing ribs connected to the support tube 312. The reinforcing ribs on 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. The radial ribs 314 radially connect the support tube 312 and the annular ribs 313. When the stepped hole is squeezed downward by the fastening bolts, the support tube 312 tends to deform. However, the radial ribs 314 and the annular ribs 313 act together to generate a tensile force on the support tube 312, thereby reducing the deformation of the support tube 312 and increasing its strength. This, in turn, increases the strength of the first shell 321 at the fastening bolts.

[0110] 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. Figure 17 The upper wall of the second shell 322 is provided with a convex ring 315 that abuts against the annular rib 313, that is, the convex ring 315 located in the second shell 322 generates an abutting force on the annular rib 313 located in the first shell 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 convex ring 315 and the annular rib 313 can reduce the deformation of the annular rib 313, that is, the strength of the first shell 321 at the fastening bolt is further improved.

[0111] In some optional embodiments, the upper wall of the protruding ring 315 is higher than the lower end of the support tube 312. As described above, water above the first housing 321 may flow downward along the stepped hole. The upper wall of the protruding ring 315 is higher than the lower end of the support tube 312, indicating a height difference between the two. Rainwater may enter the display housing 32 through the protruding ring 315 only when water accumulates on the protruding portion 210 and the water level is higher than the protruding ring 315. However, the gap between the support tube 312 and the fastening bolts is significantly smaller, and a large amount of water will not flow in a short period of time. In other words, rainwater will not enter the display housing 32 through the protruding ring 315, thereby reducing the possibility of water entering the display housing 32.

[0112] In some optional embodiments, refer to the attached Figure 7 The display screen assembly 3 is also equipped with a switch assembly, that is, the connection portion of the display screen assembly 3 is equipped with a switch assembly, which includes a vehicle switch 34 and / or an operating component control switch 35. The vehicle switch 34 is used to control whether the multi-functional operating vehicle is in the power-on state. When the user starts driving the vehicle, the vehicle should be powered on by operating the vehicle switch 34, and then the vehicle operation is controlled by components such as the active steering assembly. The operating component control switch 35 is used to control the start or stop of outdoor operating components when the vehicle is powered on. After the vehicle has completed the operation, the operating component control switch 35 is used to control the start or stop of outdoor operating components to achieve the operation in the working area.

[0113] Reference Attachment Figure 6 The assembly surface 206 of the side cover 2 is provided with 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 extending downward and passing 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.

[0114] The switch assembly is located on the side of the steering hole 33 closest to the vehicle interior. As previously mentioned, the active steering assembly is located within the steering hole 33. As a component that is operated significantly more frequently than the switch assembly, the user's grip on the active steering assembly is significantly higher than the side cover 2, thereby preventing 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 closest to the vehicle interior, in the left-right direction of the vehicle.

[0115] That is, for the embodiment in which the display screen assembly 3 is disposed on the right side of the vehicle, the switch assembly is located on the left side of the steering hole 33. For the embodiment in which the display screen assembly 3 is disposed on the left side of the vehicle, the switch assembly is located on the right side of the steering hole 33.

[0116] In some optional embodiments, refer to the attached Figure 1 , Attachment Figure 2 The active steering component is a joystick 4 that passes through the steering hole 33 of the display assembly and bends toward the middle of the vehicle. It may also deflect outward. In this embodiment, the switch component is arranged on the left side of the steering hole 33 to avoid interference with the switch component when the joystick 4 deflects outward.

[0117] In some optional embodiments, in order to facilitate user interaction with the vehicle's control system through the display screen assembly 3, the display unit 31 of the display screen assembly 3 is configured with buttons for user operation. The user can adjust the content displayed by the display unit 31 through the buttons, or send instructions to the vehicle through the buttons.

[0118] In some optional embodiments, the display unit 31 is not suitable for water to enter, and the physical button is prone to gaps in the display unit 31. Therefore, a waterproof component is required to be configured at the button to prevent water from penetrating into the display unit 31 through the gaps in the physical button. Figure 19 , the button of the display unit 31 in the figure is marked as "key body 3111".

[0119] In some optional embodiments, refer to the attached Figure 18 The figure shows a schematic structural diagram of the first housing 321. The first housing 321 is configured with a keyhole 3211 for the button to pass through. The keyhole 3211 is equipped with a flexible seal 3112. The first housing 321 and the display unit 31 jointly squeeze the seal 3112 to form a sealed space surrounding the button, preventing external water from entering the display unit 31 through the gap. This allows the display assembly to maintain normal operation in rainy environments. Vehicles equipped with the display assembly of this embodiment can function normally in rainy environments.

[0120] In order to reduce weight and save material costs, the first shell 321 is generally made of plastic and is fixed to the display unit 31 by bolts. In some embodiments, in order to enhance the effect of user interaction with the vehicle through buttons, two or more buttons are generally configured, and each button is provided with a keyhole 3211 and a seal 3112. For a display unit 31 with a slightly smaller size, the sealing effect of the seal 3112 can still be effectively maintained by the bolts at the edge; however, for a display unit 31 with a slightly larger size, it is difficult for the first shell 321 made of plastic to maintain a large rigidity at its center position, so that the extrusion force between it and the seal 3112 may be slightly smaller and cannot effectively meet the sealing effect.

[0121] Therefore, in some optional embodiments, refer to the attached Figure 18The display unit 31 is provided with at least two buttons at intervals, the first shell 321 is provided with at least two key holes 3211, and a bolt is provided between at least two of the key holes 3211 of the first shell 321. The bolt here mainly plays a sealing effect. To distinguish it from the bolts in other positions, the bolts here will be collectively referred to as "sealing bolts 3113" below. This is only named according to the function of the bolt, and does not necessarily refer to the specific type of bolt. That is, in this embodiment, the bolt here can be any bolt that can effectively fasten the first shell 321 and the display unit 31 and squeeze the seal 3112.

[0122] The sealing bolts 3113 connect the first housing 321 and the display unit 31 and compress the sealing member 3112. The sealing bolts 3113 work together with the bolts at the edge of the display unit 31 that engage the first housing 321 to achieve a sealing effect at the sealing member 3112. Specifically, the presence of the sealing bolts 3113 increases the rigidity of the first housing 321 at the sealing member 3112, thereby enabling the first housing 321 to achieve a tight abutment with the display housing 32. This in turn enables the abutment between the sealing member 3112 and the display housing 32 to achieve an effective seal, thereby creating an effective sealed space and achieving a waterproof technical effect.

[0123] In some optional embodiments, refer to the attached Figure 18 In the figure, the first housing 321 is linearly arranged with five keyholes 3211, and the first housing 321 is configured with four sealing holes 3212. The sealing bolts 3113 pass through the sealing holes 3212 and are threadedly connected to the display unit 31, wherein two sealing holes 3212 are respectively located between two of the keyholes 3211. Specifically, the five keyholes 3211 and the four sealing holes 3212 are linearly arranged 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 key holes 3211 can be freely adjusted according to the required number of buttons, but in order to enable the seal 3112 to effectively complete the sealing at the button, there is at least one sealing hole 3212 located between the two key holes 3211, so that the seal 3112 at the key hole 3211 can effectively produce a sealing effect on the button after the larger first shell 321 is matched with the display unit 31.

[0124] In another alternative embodiment, the first housing 321 is not provided with 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 threadedly connected to the internal thread of the first housing 321, thereby squeezing the sealing member 3112 to achieve a sealing effect. In this embodiment, the sealing bolt 3113 is not directly exposed to the outside world, which not only makes the outer shell of the first housing 321 look simpler, but also prevents the sealing bolt 3113 from rusting due to contact with rainwater.

[0125] In some optional embodiments, refer to the attached Figure 7 , Attachment Figure 20 The display unit 31 also includes a tilted screen, and the display housing 32 is provided with a screen hole for exposing the screen. For some embodiments, it is difficult to maintain a complete seal at the lower edge 3213 where the display unit 31 and the screen hole meet, that is, 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. Figure 13 The bottom of the second housing 322 is provided with a drain hole 3221 so that the water in the second housing 322 can flow out. As shown in the figure, two drain holes 3221 are provided in the figure, so that water can be drained smoothly when one of the drain holes 3221 is blocked.

[0126] In some optional embodiments, the display unit 31 is provided with a touch screen that can be controlled by the user, so the screen hole should be a through hole instead of a transparent glass layer that affects the touch control.

[0127] In some optional embodiments, refer to the attached Figure 14 A signal line hole 36 is provided on a side of the display unit 31 away from the first shell 321. A wire (not shown) connecting the screen and the riding lawn mower passes through the signal line hole 36, and the signal line hole 36 is coated with sealant (not shown).

[0128] In some optional embodiments, the multifunctional working vehicle further comprises a passive wheel 8 and a seat 5; wherein the passive wheel 8 is disposed at the front portion of the vehicle frame 1 on one side of the display screen assembly 3; and is used to carry a user; and the passive wheel 8 is at least partially visible to the driver sitting in the seat 5 without being blocked by the display screen assembly 3. Figure 1 , Attachment Figure 2 The multifunctional working vehicle shown in the figure includes two universal wheels, one of which is located at the front of one side of the display screen assembly 3, that is, the aforementioned passive wheel 8.

[0129] The passive wheel 8 is visible to the user, unobstructed by the display screen. This allows the user to determine the edge of the work area while driving the vehicle and performing work, thereby preventing omissions. Specifically, in some optional embodiments, the outdoor work component is a cutting table 6 equipped with a cutting blade, and the multi-functional work vehicle is a lawn mower. When a user drives the lawn mower to mow the lawn, they need to move back and forth in a zigzag pattern. During straight-line driving, the current mowing area is generally slightly overlapped with the previously mowed area to avoid missing grass. Therefore, the user needs to constantly know whether the current mowing area meets the expectations. In this embodiment, a portion of the passive wheel 8 is visible and unobstructed, and the user's line of sight when looking at the passive wheel 8 is highly similar to their line of sight when looking at the display screen assembly 3. Therefore, the user can quickly switch between looking at the passive wheel 8 and looking at the display screen assembly 3. Furthermore, when looking at the outline of the passive wheel 8, the outline can be compared with the previously mowed area on the ground, and the relative positional relationship between the current mowing area and the previously mowed area can be determined based on the user's experience. If the current mowing area does not overlap with the mowed area or the overlap is too large, the vehicle's direction should be adjusted through the active steering component until the current mowing area overlaps with the mowed area by a small amount.

[0130] That is, the display screen assembly 3 does not block or does not completely block the user's view of the passive wheel 8, so that the user can judge whether the vehicle position and angle are appropriate based on the positional relationship between the passive wheel 8 and the mowed area, and when looking at the passive wheel 8, the user's peripheral vision can also clearly notice the changes in the content of the display screen assembly 3. If the display screen assembly 3 has alarms or other information reminders, the user will be notified more promptly.

[0131] In some optional embodiments, in order for the user to clearly see the information on the display unit 31, the display unit 31 needs to be oriented relatively close to pointing towards the user's head. For the convenience of expression and understanding, the following definitions are made: the first plane is parallel to the ground; the front and rear direction of the vehicle is the first direction; the second plane passes through the first direction and is perpendicular to the first plane.

[0132] 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 the first straight line in the first plane and the first direction is less than or equal to 40 degrees. Figure 21 In the figure, straight line a is the projection of the first straight line on the first plane, and straight line b is parallel to the first direction, that is, the angle α between straight line a and straight line b is ≤ 40°; the angle between the projection of the first straight line in the second plane and the first direction is less than or equal to 50°, refer to the attached figure. Figure 22, straight line c in the figure is the projection of the first straight line on the second plane, straight line d is parallel to the first direction, then the angle β between straight line c and straight line d is ≤50°.

[0133] The component of the vehicle closest to the user's head is the backrest of the seat 5. Therefore, the line connecting the center of the top of the seat 5 and the center of the display unit 31 is relatively close to the user's line of sight. When the user is driving the vehicle normally, their line of sight is more often directed in the first direction straight ahead. Therefore, the angle between the projection of the first straight line in the first plane and the first direction, as well as the angle between the projection of the first straight line in the second plane and the first direction, can be used to express the deflection angle of the user's line of sight when they need to look at the display screen. Angles of 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 clearly see the display screen.

[0134] In some optional embodiments, the projection of the first straight line on the first plane forms an angle greater than or equal to 20° and less than or equal to 40° with the first direction. Furthermore, in some optional embodiments, the projection of the first straight line on the second plane forms an angle greater than or equal to 30° and less than or equal to 50° with the first direction. This means that the display screen is clearly positioned diagonally below the seat 5, preventing the display unit 31 from obstructing the view ahead of the vehicle and impacting outdoor operations.

[0135] In some optional embodiments, it is further defined that a straight line passing through the center of the display unit 31 and perpendicular to the plane of the display unit 31 is a second straight line.

[0136] In some optional embodiments, the angle between the projection of the second straight line in the first plane and the first direction is greater than or equal to 5° and less than or equal to 25°. Figure 23 The figure shows a top view of the side cover 2, straight line e is the projection of the second straight line in the first plane, and straight line f is parallel to the first straight line. The angle δ between straight line e and straight line f in the figure is in the range of 25°≥δ≥5°, that is, the display unit 31 is tilted to a certain extent toward the side of the seat 5 from the perspective of the top view.

[0137] The included angle between the projection of the second straight line in the second plane and the first direction is greater than or equal to 40° and less than or equal to 65°. Figure 24 The figure shows a side view of the side cover 2, straight line g is the projection of the second straight line in the second plane, straight line h is parallel to the first straight line, and the angle ε between straight line g and straight line h in the figure is in the range of 65°≥ε≥40°, that is, the display unit 31 is tilted upward to a certain extent in the perspective of the side view.

[0138] The above-mentioned angles δ and ε represent the orientation of the display unit 31, specifically the orientation of the screen portion of the display unit 31, which primarily affects whether it is facing 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 in the first plane and the first direction is greater than or equal to 10° and less than or equal to 20°, that is, 20° ≥ δ ≥ 10°; further, in some optional embodiments, the angle between the projection of the second straight line in the second plane and the first direction is greater than or equal to 50° and less than or equal to 60°, and 60° ≥ ε ≥ 50°. Within this angle range, the user sitting in the seat 5 can relatively clearly see the information displayed on the display unit 31.

[0139] In some optional embodiments, on the side of the display unit 31 near the seat 5, the second straight line is positioned higher than the first straight line, meaning that the display unit 31 is tilted toward directly above or diagonally above the seat 5. Because the first straight line and the second straight line intersect at the display unit 31, the first straight line and the second straight line are coplanar and have an angle therebetween, and the angle between the first straight line and the second straight line is greater than or equal to 15° and less than or equal to 50°. Because the user's head will be higher than the top of the seat 5 when sitting in the seat 5, the tilt of the display unit 31 toward directly above or diagonally above the seat 5, that is, closer to the user's eyes, makes it easier for the user to clearly see the information on the display unit 31.

[0140] 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 on the seat 5, the user's eyes are located within this angle range, so that the user can see the information of the display unit 31 more clearly.

[0141] In some optional embodiments, the maximum viewing angle of the display unit 31 is 40° to 70°. That is, any line of sight whose angle with the normal to the plane of the display unit 31 is less than the maximum viewing angle range can effectively see the content displayed on the display unit 31.

[0142] 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 450 mm to 750 mm, that is, Figure 21 The value of the middle X is 450mm to 750mm. In another more specific embodiment, the distance between the center of the top 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. The user can touch the display unit 31 by extending their arm or leaning forward slightly. In other words, this distance range is significantly more ergonomic.

[0143] In some optional embodiments, the present specification also discloses a multi-functional work vehicle, which includes the frame 1, user platform, outdoor work components, drive wheels 7, side covers 2, display screen assembly 3 and active steering assembly as described above, wherein the frame 1 extends along a first direction, which is the front and rear direction of the vehicle; the user platform is configured on the frame 1 and is used to carry the user; the outdoor work components are configured on the frame 1 and are used to perform outdoor work; the drive wheels 7 are configured on the left and right sides of the frame 1 and are used to drive the vehicle; the side covers 2 are configured on the frame 1, and the side covers 2 are located on the left and / or right sides of the vehicle; the display screen assembly 3 is configured on the side front of the seat 5 and is used to display patterns or character information to the user; the active steering assembly is operably configured on the frame 1 to control the speed change of the drive wheels 7 on at least one side of the vehicle.

[0144] In some optional embodiments, the orthographic projections of the active steering assembly, display assembly 3, side cover 2, and vehicle frame 1 on the ground at least partially overlap. This means that the horizontal spacing between the active steering assembly, display assembly 3, and side cover 2 is relatively small. When a user looks at the active steering assembly, they can see the contents of the display in their peripheral vision. This means that the user can obtain timely vehicle status information through the display unit 31 during operation, thereby improving vehicle safety.

[0145] In some optional embodiments, the display screen assembly 3 is further configured with a switch assembly, that is, the connection portion of the display screen assembly 3 is configured with a switch assembly, and the switch assembly includes a vehicle switch 34 and / or an operating component control switch 35. The vehicle switch 34 is used to control whether the multifunctional operating vehicle is in a powered-on state. When the user starts driving the vehicle, the vehicle should be powered-on by manipulating the vehicle switch 34, and then the vehicle operation is controlled by components such as the active steering assembly. The operating component control switch 35 is used to control the start or shut down of the outdoor operating components when the vehicle is powered-on. After the vehicle has driven to the end of the operation, the operating component control switch 35 is used to control the opening and closing of the outdoor operating components to achieve the operation in the operating area.

[0146] In some optional embodiments, the display screen assembly 3 includes a display unit 31 and a display housing 32 that at least partially encloses the display unit. The active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 are located closer to the rear of the vehicle relative to the display unit 31. In other words, the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 are located closer to the user relative to the display unit 31, thereby facilitating manual control of the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 by the user. Because the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 are relatively close to the display unit 31, when the user is looking at the active steering assembly and / or the vehicle switch 34 and / or the operating component control switch 35 and operating them, their peripheral vision can observe the content displayed on the display unit 31. In other words, the user can obtain vehicle status information through the display unit 31 in a timely manner during operation, thereby improving vehicle safety.

[0147] In some optional embodiments, refer to the attached Figure 25 The display unit 31 includes at least one button for user manipulation. At least one of the buttons is spaced 20 mm to 100 mm from the vehicle switch 34 or the operating unit control switch 35 in the first direction, i.e., the range of Y in the accompanying drawings is 20 mm to 100 mm. As described above, the close spacing between the display unit 31 and the vehicle switch 34 or the operating unit control switch 35 facilitates the user's access to vehicle status information. However, when the user manipulates the vehicle switch 34 or the operating unit control switch 35, the display unit 31 should not interfere with the user's hand. In other words, the display unit 31 should not block the user's hand from manipulating the vehicle switch 34 or the operating unit control switch 35. This spacing of 100 mm or less in the first direction provides sufficient space for the user's hand to move. In some embodiments, the button of the display unit 31 is offset from the vehicle switch 34 or the operating unit control switch 35 in the left-right direction of the vehicle. Therefore, appropriately shortening the spacing between the button and the vehicle switch 34 or the operating unit control switch 35 in the first direction will prevent interference. However, for the convenience of layout, it is still necessary to configure the button to have a spacing of 20mm between it and the whole vehicle switch 34 or the operating component control switch 35 along the first direction; in summary, that is: the spacing between at least one of the buttons and the whole vehicle switch 34 or the operating component control switch 35 in the first direction is 20mm to 100mm.

[0148] In some optional embodiments, the seat 5 supporting the user includes a seat cushion and a backrest, and the distance between at least one of the buttons and the top center of the backrest in the 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 is consistent with the arm length of a normal adult, and the user can operate the button by extending their arm or leaning forward slightly. In other words, the above distance range is significantly more ergonomic.

[0149] In some optional embodiments, refer to the attached Figure 1 , Attachment Figure 2 The multifunctional working vehicle only includes one display screen assembly 3, wherein one active steering assembly passes through the display screen assembly 3. The user only needs to look to one side to obtain the information displayed by the display screen assembly 3.

[0150] As described above, the multi-purpose work vehicle includes two active steering assemblies, and the active steering assemblies control the rotational speed of the corresponding drive wheels 7 when they move forward and backward. In some more specific embodiments, the display screen assembly 3 is provided with a steering hole 33 for the corresponding active steering assembly to pass through. The display screen assembly 3 includes a display portion and a connecting portion, with the steering hole 33 disposed in the connecting portion. The display screen assembly 3 is relatively close to the corresponding active steering assembly, allowing the user to more easily view the information displayed on the display screen assembly 3 when looking at the active steering assembly.

[0151] In some more specific embodiments, forward movement of the active steering assembly controls the forward rotation of the corresponding drive wheel 7, while backward movement of the active steering assembly controls the backward rotation of the corresponding drive wheel 7. The greater the movement of the active steering assembly, the faster the speed of the corresponding drive wheel 7. When the speeds of the drive wheels 7 on both sides are unequal, the vehicle will turn. Thus, the two active steering assemblies control the forward and backward travel and turning of the vehicle through their respective movement amounts.

[0152] In some of the more specific embodiments, the active steering assembly can also move in the left and right directions. Figure 5 , Attachment Figure 7 After the right active steering assembly moves to the right, it is limited by the steering hole 33 and can no longer move forward and backward. After the left active steering assembly moves to the left, it can no longer move forward and backward. And the right active steering assembly moving to the right or the left active steering assembly 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 wheel 7 can be controlled to rotate.

[0153] In some optional embodiments, refer to the attached Figure 1 , Attachment Figure 2The display screen assembly 3 is arranged on the right side of the vehicle, and the corresponding steering hole 33 is configured as a T-shaped hole (T-shaped horizontally) that can move to the right when the active steering assembly moves to the middle position in the front-to-back direction, that is, the active steering assembly does not interfere with the side wall of the steering hole 33 when moving forward, backward or to the right.

[0154] In some more specific embodiments, for a user on the user platform, when the active steering assembly moves rightward, placing the vehicle in a parked state, the display unit 31 is visible and unobstructed by the active steering assembly. In the parked state, the wheels do not rotate, meaning they are in a safe state. In this state, the display unit 31 should be freely controllable by the user, so the active steering assembly should be configured to not obstruct the display unit 31.

[0155] In some optional embodiments, when the active steering assembly moves to the left and can move forward and backward along the steering hole 33, the display unit 31 is partially blocked by the active steering assembly and is not fully visible. This is because when the active steering assembly is in a state where it can move forward and backward along the steering hole 33 and the vehicle is in a non-parked state, the vehicle may be or is moving and is dangerous. At this time, the display unit 31 should only be used as a display component. It is not advisable for the user to separate his hand from the active steering assembly and touch the display unit 31. Therefore, the active steering assembly is set to block the display unit 31. Even if the user's hand releases the active steering assembly, it will inevitably be blocked by the active steering assembly and it will be difficult to touch the display unit 31. In other words, the user is forced to control the active steering assembly to move 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.

[0156] In some more specific embodiments, the display screen assembly 3 does not significantly protrude upward beyond the highest point of the side cover 2. In other words, the display screen assembly 3 is approximately the same height as or lower than the corresponding side cover 2. As previously mentioned, the display unit 31 of the display screen assembly 3 protrudes forward from the side cover 2. This embodiment prevents the display screen assembly 3 from significantly protruding upward to reduce the likelihood of collision with external objects. When an external object potentially impacts the vehicle of this embodiment laterally, the side cover 2 is more likely to bear the impact force, preventing damage to the display screen assembly 3, thus preventing damage to this relatively fragile component and potentially causing greater economic losses.

[0157] In some optional embodiments, refer to the attached Figure 1 , Attachment Figure 6The side cover 2 is provided with a height adjustment slot 205, through which a height adjustment lever 10 is operatively connected to the vehicle frame 1. Rotation of the height adjustment lever 10 adjusts the height of the outdoor work components above the ground to accommodate the practical needs of different users for outdoor work. The height adjustment lever 10 is located closer to the rear of the vehicle relative to the display assembly 3. Because outdoor work components can be heavy, the rearward position of the height adjustment lever 10, i.e., closer to the user, facilitates the user's adjustment of the height of the outdoor work components.

[0158] In some optional embodiments, refer to the attached Figure 4 The vehicle frame 1 includes a main frame and a bridge member 101 fixed to the main frame. The bridge member 101 is a metal connector used to assist in the installation of the side cover 2, the display housing 32, etc., and can be considered as part of the vehicle frame 1. Furthermore, in this embodiment, the display housing 32, the side cover 2, and the bridge member 101 are all provided with a steering hole 33 for the active steering assembly to pass through.

[0159] In some optional embodiments, the multifunctional working vehicle further includes a vehicle controller (not shown) for controlling the working state of the vehicle, the vehicle switch 34 and / or the working component control switch 35 are connected to the vehicle controller via a wire, and the side cover 2 is provided with a wire hole for the vehicle switch 34 and / or the working component control switch 35 or the wire to pass through, see attached Figure 6 .

The sealing hole 3212 is provided with a bolt that fastens the first housing 321 and the display unit 31 and compresses the sealing member 3112.

[0169] In another optional embodiment, the present specification also discloses a multifunctional work vehicle, which includes the frame 1, outdoor work components, side cover 2 and display screen assembly 3 as described above, wherein the frame 1 extends along a first direction, which is the front and rear direction of the vehicle; the outdoor work components are arranged on the frame 1 and are used to perform outdoor work; the side cover 2 is arranged on the left side and / or right side of the frame 1; the display screen assembly 3 is arranged on the side cover 2 and is used to display pattern or character information to the user.

[0170] In some optional embodiments, refer to the attached Figure 3 The display housing 32 of the multi-purpose work vehicle includes a connecting portion connected approximately horizontally to the side cover 2 and a display portion extending in a direction different from that of the connecting portion. The display screen assembly 3 includes a display unit 31 disposed within the display portion and configured to display graphic or text information. Specifically, the display screen assembly 3 includes two portions extending in different directions, and the connecting portion maintains a substantially horizontal position in contact with the side cover 2. The display portion is tilted toward the user's face, eliminating the need for the user to significantly tilt their head downward to clearly view the information on the display unit 31.

[0171] It should be noted that the aforementioned "substantially horizontal" connection should be understood as having a small angle with the horizontal direction. For example, if the angle with the horizontal direction is within the range of ±15°, it should be understood as being substantially horizontal. This is because within this angle range, the naked eye cannot clearly observe that the connection is not horizontal.

[0172] In some optional embodiments, refer to the attached Figure 1 , Attachment Figure 2The multifunctional work vehicle also includes a user platform for carrying a user. 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, so that the user can clearly see the information displayed by the display unit 31.

[0173] In another optional embodiment, refer to the attached Figure 1 , Attachment Figure 2 , also disclosed is a multifunctional work vehicle, which includes a frame 1, outdoor work components, side covers 2, and a display screen assembly 3, wherein the frame 1 extends along a first direction, which is the front and rear direction of the vehicle; the outdoor work components are configured on the frame 1 and are used to perform outdoor work; the side covers 2 are configured on the frame 1 and are located on the left and / or right side of the vehicle; the display screen assembly 3 is configured on the side covers 2 and is used to display pattern or character information to the user.

[0174] In some optional embodiments, refer to the attached Figure 1 , Attachment Figure 2 The display screen assembly 3 includes a connection portion connected approximately horizontally to the side cover 2 and a display portion extending in a direction different from the connection portion. The display screen assembly 3 includes a display unit 31 configured to display pattern or character information. Specifically, the side cover 2 includes a substantially horizontal mounting surface 206, and the display screen assembly 3 includes a first surface 37 for mating with the mounting surface 206. The purpose of the substantially horizontal first surface 37 and the mounting surface 206 is to prevent the display screen assembly 3 from sliding or deviating due to its weight when placed on the mounting surface 206 during assembly, thereby facilitating assembly.

[0175] The display portion in this embodiment extends in a different direction than the connecting portion because the display portion is primarily used to display patterns or character information to the user via the display unit 31. As previously mentioned, the connecting portion extends horizontally, and the plane of the connecting portion faces directly upward. If the user looks at the connecting portion, they must lower their head to orient their gaze vertically downward in order to clearly see the characters on the surface of the connecting portion. The display portion extends in a different direction than the connecting portion, meaning that the display unit 31 is tilted relative to the horizontal plane, allowing the user to see the content displayed by the display unit 31 without having to significantly lower their head.

[0176] In some optional embodiments, the multi-functional work vehicle includes a user platform for carrying a user, and the normal of the plane on which the display unit 31 displays the pattern is directed directly above the user platform. When the user is on the user platform, the user's head is naturally positioned directly above the user platform. In this embodiment, the normal of the plane on which the display unit 31 displays the pattern is directed directly above the user platform, that is, approximately toward the user's head, thereby facilitating the user's viewing of the pattern or text 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 on which the pattern is displayed is also the screen surface.

[0177] In some optional embodiments, the connection portion is configured with a switch assembly, which includes a vehicle switch 34 and / or an operating component control switch 35; the vehicle switch 34 is used to control whether the multifunctional operating vehicle is in the power-on state; the operating component control switch 35 is used to control the activation or deactivation of the outdoor operating components when the vehicle is in the power-on state. In other words, the switch assembly and the display unit 31 are both located in the display screen assembly 3, and the user can 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 by the display unit 31 to confirm whether the vehicle's status meets the user's expectations.

[0178] In some optional embodiments, the multifunctional work vehicle further includes a drive wheel 7 and an active steering assembly; the drive wheels 7 are arranged on the left and right sides of the frame 1 and are used to drive the vehicle; the active steering assembly is operably rotatably connected to the left and / or right side of the frame 1, and is used to generate a speed difference between the drive wheels 7 on both sides to cause the vehicle to turn.

[0179] 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, so as to prevent the display unit 31 from affecting the operation of the active steering component.

[0180] In some optional embodiments, the display housing 32 is provided with a steering hole 33 penetrated by an active steering component. When the active steering component is controlled by a user to move forward or backward in the steering hole 33, it controls the speed change of the driving wheel 7 on at least one side. The steering hole 33 is configured as a T-shaped hole that can move left or right when the active steering component moves to the middle position in the front-to-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.

[0181] In some more specific embodiments, for a user on the user platform, when the active steering assembly moves rightward, placing the vehicle in a parked state, the display unit 31 is visible and unobstructed by the active steering assembly. In the parked state, the wheels do not rotate, meaning they are in a safe state. In this state, the display unit 31 should be freely controllable by the user, so the active steering assembly should be configured to not obstruct the display unit 31.

[0182] In some optional embodiments, the display unit 31 includes a touch screen that can be touched by a user, and the user can complete signal input to the display unit 31 through touch to control the status of the vehicle.

[0183] In some optional embodiments, when the active steering assembly moves to the left and can move forward and backward along the steering hole 33, the display unit 31 is partially blocked by the active steering assembly and is not fully visible. This is because when the active steering assembly is in a state where it can move forward and backward along the steering hole 33 and the vehicle is in a non-parked state, the vehicle may be or is moving and is dangerous. At this time, the display unit 31 should only be used as a display component. It is not advisable for the user to separate his hand from the active steering assembly and touch the display unit 31. Therefore, the active steering assembly is set to block the display unit 31. Even if the user's hand releases the active steering assembly, it will inevitably be blocked by the active steering assembly and it will be difficult to touch the display unit 31. In other words, the user is forced to control the active steering assembly to move 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.

[0184] In another optional embodiment, a riding lawn mower is also disclosed, which includes the frame 1 described above, outdoor work components, side covers 2, and a display screen assembly 3; wherein the frame 1 extends generally along a first direction, and the outdoor work components are configured as a cutting table 6 assembled to the frame 1 and used to perform lawn mowing operations.

The display screen assembly 3 includes an area of ​​not less than 80cm 2 screen. Its relatively large screen size enables it to present more information to the user. In addition, the larger screen can also display the corresponding information with larger icons or font sizes, so that users can more easily distinguish the information displayed on the screen, improving the practicality of the screen. In addition, because the screen is larger, it can display more information, that is, the user can obtain more information within one interface of the screen, and the user can also make the best decision about outdoor work based on the more information obtained. For example, the user can obtain information such as the remaining range, the remaining area to be worked, the time or the weather conditions in the next few hours at the same time within one interface of the screen, and then make the best decision whether to continue the work.

[0187] In some optional embodiments, the screen area S of the display screen assembly 3 is greater than or equal to 100 cm 2 In another optional embodiment, the screen area S of the display screen assembly 3 is greater than or equal to 120 cm 2As mentioned above, a larger screen can display more information.

In summary: the replacement of the outdoor work component with any functional component according to user needs should not be understood as exceeding the scope of protection of this embodiment.

[0204] As mentioned above, the working vehicle equipped with a power supply system is a rechargeable working vehicle. Compared with traditional fuel-powered working vehicles, the rechargeable working vehicle has 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 rechargeable working vehicle uses an electric motor instead of a fuel engine, and can control the electric motors of the drive wheels 7 separately to realize the vehicle's straight-moving, reverse, turning, zero-turn and other motion control, reducing the structural complexity of the vehicle and making the control of the vehicle more flexible.

[0205] Similarly, a garden vehicle equipped with a power supply system is a rechargeable garden vehicle, which also has the above-mentioned beneficial effects.

[0206] Referring to the accompanying drawings, the work vehicle shown in the figure is equipped with a steering rod. The user controls the steering rod to change the speed of the drive wheel 7 and then controls the vehicle. In other embodiments, the steering rod can also be changed to a steering wheel-type structure, that is, the control method of vehicle steering should not be understood as exceeding the protection scope of this embodiment.

[0207] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus.
