For example, the words indicating orientation or positional relationship such as "upper", "lower", "front", "rear", etc. are only based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model.

[0083] Unless otherwise specified, the terms "arranged", "connected" and "coupled" in the present utility model should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. The "fixed connection" in the present utility model should also be understood in a broad sense as integrally formed, welded or connected by other fasteners.

[0084] This embodiment discloses a multi-functional work vehicle. Refer to the attached Figure 1 , which includes a vehicle frame 1, an outdoor work component, and a seat 5; the vehicle frame 1 extends along a first direction, which is also the forward direction of the vehicle; the outdoor work component is arranged on the vehicle frame 1 and is used for performing outdoor work; the seat 5 is arranged on the vehicle frame 1 and is used for carrying a user.

[0085] To make the vehicle more aesthetically pleasing, generally, covering parts on the left side and / or right side and / or rear side of the vehicle are also arranged. In one optional embodiment, refer to the attached Figure 1 , the multi-functional work vehicle includes a side covering part 2. The side covering part 2 shown in the figure is located on the right side of the vehicle, and the side covering part 2 in the figure is also provided with a display screen assembly 3, and the display screen assembly 3 can display pattern or character information to the user when powered on; in another optional embodiment, the side covering part 2 provided with a display screen can also be arranged on the left side of the vehicle. In another optional embodiment, side covering parts 2 are arranged on both the left side and the right side of the vehicle, and display screen assemblies 3 capable of displaying pattern or character information to the user are arranged on both sides. It should be noted that to make the position of the side covering part 2 relatively stable on the vehicle, it is fixed to the vehicle frame 1 through fasteners such as bolts.

[0086] In some optional embodiments, the seat 5 includes a seat cushion and a backrest, and the backrest is for the user to lean on when sitting on the seat cushion. Looking at the front of the vehicle along the center of the top of the backrest, the side front outer contour of the vehicle 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 arranged 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, that is, it will not affect the user's judgment of the position relationship between the vehicle and the 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 judge the vehicle position relationship.

[0087] It should be noted that the top of the backrest of the seat 5 is the entity position on the vehicle closest to the user's head. Therefore, looking at the front of the vehicle along the center of the top of the backrest is approximately: the line of sight of the user sitting on the seat 5 looking at the front of the vehicle. Therefore, refer to the attached Figure 2 , the side front outer contour of the vehicle in front of the display screen assembly 3 is visible to the user sitting on the seat 5, that is, the user's line of sight can see the ground through the side front outer contour of the vehicle. The attached Figure 2The shaded part described above is the area where the user can see the ground along the outer contour of the side front of the vehicle. The aforementioned outer contour of the side front of the vehicle is: taking the head of the user driving the vehicle as the starting point of the line of sight, looking at the outer contour in front of one side of the vehicle.

[0088] When performing outdoor operations on the ground, the work vehicle will first drive straight. When it reaches the edge of the operation area, it will turn around and drive in the opposite direction of the original direction, and the outdoor operation components will overlap slightly with the already-operated area to ensure that there will be no unoperated areas left. In this embodiment, when the overlapping area is 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 operation components; but as described above, the front outer contour of the wheel in front of the display screen assembly 3 is visible to the user sitting on the seat 5, and for the same user, the coverage range of the outdoor operation components of the vehicle remains unchanged relative to the outer contour of the vehicle that the user looks at by himself. Therefore, the user can judge the overlapping degree between the coverage range of the outdoor operation components and the already-operated area by observing the positional relationship between the boundary of the already-operated area and the outer contour of the vehicle. In other words, the user judges the overlapping degree between the coverage range of the outdoor operation components and the already-operated area by the position of the boundary of the already-operated area relative to the outer contour of the vehicle in the field of vision. Thus, it is possible to avoid unoperated areas being left on the ground after the operation.

[0089] In some alternative embodiments, the multi-functional work vehicle further includes a driven wheel 8 disposed at the front part of the vehicle frame 1 on one side of the display screen assembly 3. Refer to the attached Figure 1 , the multi-functional work vehicle shown in the figure includes two universal wheels located in front of the vehicle. The universal wheel located on the side of the display screen assembly 3 is the aforementioned driven wheel 8, and this driven wheel 8 is the component closest to the front edge of the vehicle.

[0090] In this embodiment, looking along the center of the top of the backrest towards the front of the vehicle, at least part of the driven wheel 8 is not blocked by the display screen assembly 3 but is visible, that is, at least part of the driven wheel 8 can be seen by the user sitting on the seat 5. Furthermore, the user can judge the overlapping degree between the coverage range of the outdoor operation components and the already-operated area by the position of the boundary of the already-operated area relative to the outer contour of the driven wheel 8 in the field of vision. Thus, it is possible to avoid unoperated areas being left on the ground after the operation.

[0091] In some alternative embodiments, when looking forward at the vehicle along the center of the top of the backrest, a part of the passive wheel 8 is blocked by the display screen assembly 3 and thus invisible. That is to say, for a user sitting on the seat 5, it is possible to judge the overlapping degree between the coverage area of the outdoor working component and the worked area 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 vision, so as to avoid leaving unworked areas on the ground after operation. During this process, when the user judges the range of the working area, the peripheral vision can see the information displayed by the display screen assembly 3. If there are obvious changes in the information displayed by the display screen assembly 3, it will be very easy for the user to notice, so as to facilitate the user to obtain the vehicle status information from the display screen assembly 3 in time and reduce the danger caused by not obtaining the warning information of the display screen assembly 3 in time.

[0092] In other words, when the user looks at the display screen assembly 3 to obtain the vehicle status information it displays, the peripheral vision of the eyes can also see the position of the boundary of the worked area relative to the outer contour of the display screen assembly 3 in the field of vision, so as to judge the overlapping degree between the coverage area of the outdoor working component and the worked area. Or, when the user looks at the display screen assembly 3 to obtain the vehicle status information it displays, only by adjusting the gaze can the user see the position of the boundary of the worked area relative to the outer contour of the display screen assembly 3 in the field of vision, without having to turn the head, reducing the time required for the line of sight conversion, enabling the user to concentrate more on vehicle driving and improving operation safety.

[0093] In some alternative embodiments, referring to the attached Figure 6 , the side covering member 2 successively includes a lower side covering portion 201, a rising portion 202, and an upper side covering portion 203 in the vehicle's front-to-back direction. The upper side covering portion 203 is higher than the lower side covering portion 201, and the display screen assembly 3 is assembled on the lower side covering portion 201. That is to say, the display screen assembly 3 is located on the front side of the side covering member 2, so that there is a relatively obvious distance between it and the user in the first direction (the vehicle's front-to-back direction). In this embodiment, increasing the distance in the front-to-back direction can reduce the angle between the line connecting the display screen and the user's eyes and the horizontal direction, that is, to avoid the user having to lower the head significantly to see or clearly see the display screen.

[0094] In some alternative embodiments, the multi-functional work vehicle further includes drive wheels 7 and an active steering assembly. The drive wheels 7 are configured on the vehicle frame 1 and are driven by a power source configured on the vehicle frame 1 to rotate as driving wheels, thereby driving the vehicle to move forward; the active steering assembly is operably rotatably connected to the left side and / or the right side of the vehicle frame 1 and is used to generate a rotational speed difference between the drive 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 vehicle to turn. Among them, the above-mentioned power source can be an internal combustion engine or an electric motor. Although their working principles are different, they can both output torque to the tires to drive the vehicle to move forward, and power sources such as internal combustion engines and electric motors are all common existing technologies and will not be elaborated here.

[0095] In some alternative embodiments, the display screen assembly 3 includes a display unit 31 and a display housing 32. The display unit 31 can display patterns or character information when powered on to display the information of the vehicle to the user; the display housing 32 at least covers a part of the display unit 31 to fix the display unit 31.

[0096] In some alternative embodiments, at least one of the active steering assemblies penetrates through the display screen assembly 3, and the display unit 31 of the display screen assembly 3 for displaying patterns or character information is located in front of the active steering assembly.

[0097] In some alternative embodiments, the multi-functional work vehicle includes one active steering assembly. When the user controls the active steering assembly to move forward, backward, left, or right, the vehicle is respectively controlled to move in the corresponding direction. The corresponding multi-functional work vehicle includes a display screen assembly 3, and the active steering assembly penetrates through the display screen assembly 3, that is, the distance between the display screen assembly 3 and the active steering assembly is relatively close. When the user looks at the display screen assembly 3 or the active steering assembly, the user can clearly see the other one from the corner of the eye, thereby reducing the movement amount of the head or eyes of the user when driving the vehicle, reducing the driving operation difficulty, and indirectly improving the driving safety performance of the vehicle.

[0098] In some alternative embodiments, the multi-functional work vehicle includes two active steering assemblies, and the two active steering assemblies are respectively used to control the rotation of the drive wheels 7 on the corresponding sides. Refer to the attached Figure 1 , attached Figure 2 , in the figure, the joystick 4 shown is the active steering assembly, and the two joysticks 4 are respectively located on the left side and the right side of the vehicle.

[0099] In some more specific embodiments thereof, the multi-functional work vehicle includes two display screen assemblies 3 respectively located on the left and right sides of the vehicle, that is, the two display screen assemblies 3 are respectively located at the side covers 2 on the left and right sides of the vehicle, and the two display screen assemblies 3 are respectively used to display different information of the vehicle, such as: one of the display screen assemblies 3 is used to display information such as the driving speed, remaining power (or fuel quantity), tire pressure, temperature, etc. of the vehicle; the other display screen assembly 3 is used to display information such as the load level of the outdoor working components. The two active steering assemblies respectively penetrate through the display screen assemblies 3 on both sides.

[0100] In some more specific embodiments thereof, referring to the attached Figure 1 , the multi-functional work vehicle includes a display screen assembly 3, and one of the active steering assemblies penetrates through the display screen assembly 3. The user only needs to look at one side to obtain the information displayed by the display screen assembly 3.

[0101] As described above, the multi-functional work vehicle includes two active steering assemblies, and when the active steering assemblies move forward and backward, they control the rotational speed change of the corresponding drive wheels 7. In some more specific embodiments thereof, referring to the attached Figure 3 and the attached Figure 4 and the attached Figure 5 , the display screen assembly 3 is provided with a steering hole 33 for the corresponding active steering assembly to penetrate through. The display screen assembly 3 includes a display part and a connecting part, and the steering hole 33 is arranged in the connecting part. The display screen assembly 3 is relatively close to the corresponding active steering assembly, so that when the user looks at the active steering assembly, they can more conveniently see the information displayed by the display screen assembly 3.

[0102] In some more specific embodiments thereof, when the active steering assembly moves forward, it controls the corresponding drive wheel 7 to rotate forward, and when the active steering assembly moves backward, it controls the corresponding drive wheel 7 to rotate backward, and the greater the movement amount of the active steering assembly, the faster the rotational speed of the corresponding drive wheel 7. When the rotational speeds of the drive wheels 7 on both sides are not equal, the vehicle will turn. Therefore, the two active steering assemblies control the forward and backward driving and turning of the vehicle through their movement amounts.

[0103] In some more specific embodiments thereof, the active steering assembly can also move in the left-right direction. Specifically, after the active steering assembly on the right moves to the right, it can no longer move in the front-back direction, and after the active steering assembly on the left moves to the left, it can no longer move in the front-back direction; and when the active steering assembly on the right moves to the right or the active steering assembly on the left moves to the left, the vehicle will enter the parking state, and the vehicle in the parking state needs to be unlocked to control the rotation of the drive wheel 7.

[0104] In some more specific embodiments thereof, referring to the attached Figure 5 and the attached Figure 7The 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 and backward or to the right.

[0105] 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.

[0106] 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, and the height adjustment slot 205 is penetrated by a height adjustment rod 10 which is operably connected to the frame 1. When the height adjustment rod 10 rotates, the height of the outdoor working component from the ground changes. The height adjustment rod 10, the active steering assembly, and the display assembly 3 are all relatively common components for users. They are arranged on the same side of the vehicle to facilitate users to control the vehicle more conveniently.

[0107] 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 abutting against the assembly surface 206, that is, the lower covering portion and the display screen assembly 3 are in surface contact, and have a relatively large contact area. When the vehicle bumps, the squeezing 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.

[0108] 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 abutting 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 arranged 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 nearly perpendicular position relationship with 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.

[0109] 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 part 201 is provided with a limiting hole 207 penetrated by the display screen assembly 3, the second surface 38 abuts against one inner wall of the limiting hole 207, and a reinforcing rib is arranged on the inner wall of the limiting hole 207 where it abuts against the second surface 38. The first surface 37 and the second surface 38 are respectively located on opposite sides of the display screen assembly 3. In the figure, the shown first surface 37 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 extends at least partially along the extending direction of the inner wall of the limiting hole 207, so as to improve the strength of the corresponding inner wall of the limiting hole 207 and avoid the risk of fracture due to concentrated force on the inner wall.

[0110] In some more specific embodiments thereof, refer to the attached Figure 7 , attached Figure 8 , attached Figure 9 , the side covering part 2 is provided with an assembly surface 206 and a limiting hole 207, the display screen assembly 3 is provided with a first surface 37 and a second surface 38, the first surface 37 abuts against the assembly surface 206, the second surface 38 abuts against one inner wall of the limiting hole 207, and a reinforcing rib is arranged on the inner wall of the limiting hole 207 where it abuts against the second surface 38. 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 assembly surface 206, and the other inner wall of the limiting hole 207 is opposite to the assembly surface 206 and abuts against the display screen assembly 3, and a reinforcing rib is arranged on the inner wall of the limiting hole 207 opposite to the assembly surface 206.

[0111] In some alternative embodiments, at least two inner walls of the limiting hole 207 abut against the display screen assembly 3, one inner wall is flush with the aforementioned assembly surface 206, the area of this assembly surface 206 is larger and can bear a relatively large abutting force, and the area of the other inner wall is smaller. Therefore, a reinforcing rib is arranged to achieve the purpose of improving the strength of the corresponding position, avoiding damage to the limiting hole 207 due to a large pressure generated by the display screen assembly 3 on this position during the running of the vehicle, that is, ensuring that the display screen assembly 3 can be stably and effectively connected to the side covering part 2.

[0112] 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. Refer to the attached Figure 10 , attached Figure 11 , attached Figure 10 is a schematic structural diagram of the side covering part 2, attached Figure 11 is attached Figure 10A partially enlarged view, in which the reinforcing ribs in the figure include longitudinal ribs 209 and transverse ribs 208 arranged crosswise. Both the longitudinal ribs 209 and the bodies of the transverse ribs 208 are thin plate-like structures. The longitudinal ribs 209 and the transverse ribs 208 together form a grid-like reinforcing rib, increasing the strength of the side wall of the limiting hole 207 and ensuring the reliability of the connection between the display screen assembly 3 and the side cover 2.

[0113] In some alternative 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 the preliminary fixation of the display screen assembly 3.

[0114] In some alternative embodiments, one of the assembly surface 206 and the first surface 37 is configured with a protrusion 210, and the other of the assembly surface 206 and the first surface 37 is configured with a recess 39. The protrusion 210 and the recess 39 cooperate to enhance the connection strength between the two. Specifically, in some alternative embodiments, referring to the attached Figure 8 attachment Figure 9 , the assembly surface 206 is configured with an upward protrusion 210, and the first surface 37 is configured with a recess 39 that cooperates with the protrusion 210.

[0115] To fix the display screen assembly 3 to the side cover 2, it is necessary to limit the two through a locking member. In some alternative embodiments, referring to the attached Figure 4 , a locking bolt 310 in the up-down direction penetrates through the protrusion 210 and the recess 39 together. It should be particularly 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 protruding parts are perpendicular to the corresponding surfaces, so that the structural strength of the protrusion 210 and the recess 39 is greater than other positions of the corresponding surfaces. That is, the technical effect of the reinforcing rib is produced at the connection between the protrusion 210, the recess 39 and the corresponding surface, so that the first surface 37 or the assembly surface 206 can bear the large tightening force of the locking bolt 310 without being damaged. Referring to the attached Figure 4 attachment Figure 8 , the figure shows that two locking bolts 310 are configured through the protrusion 210 and the recess 39 together. Because the protrusion 210 and the recess 39 can bear a large force, it is not necessary to relatively evenly configure a larger number of bolts between the display screen assembly 3 and the side cover 2, thereby reducing the assembly difficulty. It should be additionally noted that: the protrusion 210 and the recess 39 can bear a larger tightening force because they can enhance the strength of the corresponding positions, so that the number of fastening bolts can be reduced. However, a significant increase in the locking bolt 310 due to other assembly requirements should not be understood as breaking through the protection scope of this embodiment.

[0116] In some alternative embodiments, the assembly surface 206 has a protruding portion 210 that protrudes upward. Correspondingly, the first surface 37 has a recessed portion 39 that mates with the protruding portion 210. Refer to the attached Figure 11 drawing. To further increase the strength of the protruding portion 210, reinforcing ribs, marked as protruding ribs 211, are arranged on the lower wall of the protruding portion 210. Correspondingly, to increase the strength of the recessed portion 39, refer to the attached Figure 13 drawing. The drawing shows a schematic structural view of the second housing 322, and reinforcing ribs, marked as recessed ribs 311, are also arranged on the upper wall of the recessed portion 39.

[0117] In some alternative embodiments, refer to the attached Figure 12 drawing. The display screen assembly 3 includes a display unit 31 and a display housing 32 that at least partially covers the display unit 31. The display housing 32 includes a first housing 321 and a second housing 322, and the first housing 321 is located above the second housing 322. Refer to the attached Figure 4 drawing. The locking bolt 310 sequentially passes through the first housing 321, the second housing 322, and the side cover 2 from top to bottom and is connected 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. Refer to the attached Figure 14 drawing. The drawing shows a schematic structural view of the first housing 321 and the display unit 31. The fastening bolt directly defines the distance between the frame 1 and the first housing 321, thereby fastening the display screen assembly 3 to the side cover 2.

[0118] Refer to the attached Figure 15 drawing, Figure 16 drawing, Figure 17 drawing. Figure 15 The drawing is a side view of the first housing 321 and the display unit 31. Figure 16 The drawing is Figure 15 a sectional view of the perspective shown in the drawing. Figure 17 The drawing is Figure 16 a partial enlarged view of the drawing. The support tube 312 passes through the second housing 322 downward and directly abuts against the side cover 2, which can prevent the locking bolt 310 from rotating excessively during assembly, resulting in deformation of the first housing 321 and a reduction in strength. In addition, since the support tube 312 is formed by the downward extension of the stepped hole, water above the first housing 321 may flow downward along the stepped hole. Its configuration of passing through the second housing 322 prevents the water above from flowing into the display housing 32 through the stepped hole, reducing the possibility of water entering the display housing 32.

[0119] In some alternative embodiments, in order to further increase the strength of the first housing 321 at the fastening bolt, with comprehensive reference to Appendix Figure 14 and Appendix Figure 17 , a reinforcing rib connected to the support tube 312 is disposed on the lower wall of the first housing 321. The reinforcing rib at the support tube 312 includes an annular rib 313 and a radial rib 314. The support tube 312 is located within the annular space of the annular rib 313, and the radial rib 314 is radially connected to the support tube 312 and the annular rib 313. When the stepped hole is deformed downward under the extrusion of the fastening bolt, the support tube 312 has a tendency to deform. However, the radial rib 314 and the annular rib 313 act to generate a tensile force on the support tube 312, thereby reducing the deformation amount of the support tube 312 and improving the strength of the support tube 312, that is, improving the strength of the first housing 321 at the fastening bolt.

[0120] As described above, the support tube 312 abuts against the upper wall of the side cover member 2, that is, the support tube 312 abuts against the upper wall of the protrusion 210. In some alternative embodiments, with reference to Appendix Figure 17 , a convex ring 315 that abuts against the annular rib 313 is provided on the upper wall of the second housing 322, that is, the convex ring 315 located on the second housing 322 generates an abutting force on the annular rib 313 located on the first housing 321. When the locking bolt 310 acts on the support tube 312 to generate stress on the annular rib 313, the abutting force between the convex ring 315 and the annular rib 313 can reduce the deformation amount of the annular rib 313, that is, improve the strength of the first housing 321 at the fastening bolt again.

[0121] In some alternative embodiments, the upper wall of the convex ring 315 is higher than the lower end of the support tube 312. As described above, the water above the first housing 321 may flow downward along the stepped hole. The upper wall of the convex ring 315 being higher than the lower end of the support tube 312 means that there is a height difference between the two. Only when there is water accumulation in the protrusion 210 and the water accumulation height is higher than the convex ring 315, can rainwater possibly enter the display housing 32 through 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 through in a short time, that is, rainwater will not enter the display housing 32 through the convex ring 315, reducing the possibility of water entering the display housing 32 as a whole.

[0122] In some alternative embodiments, with reference to Appendix Figure 7, the display screen assembly 3 is also configured with a switch assembly, that is, a switch assembly is configured for the connection part of the display screen assembly 3. The switch assembly includes a vehicle switch 34 and / or an operation component control switch 35. The vehicle switch 34 is used to control whether the multi-functional operation vehicle is powered on. When the user starts driving the vehicle, the vehicle should be powered on by operating the vehicle switch 34, and then the vehicle can be controlled to work through components such as the active steering assembly. The operation component control switch 35 is used to control the start or stop of the outdoor operation components when the vehicle is powered on. When the vehicle travels to the operation location, the outdoor operation components can be controlled to open or close through the operation component control switch 35 to realize the operation on the area to be operated.

[0123] Reference appendix Figure 6 , a wire passing hole 212 is provided on the assembly surface 206 of the side cover 2. The display screen assembly is configured with a switch assembly for controlling the vehicle state. The switch assembly is connected with a wire that extends downward and passes through the wire passing hole 212. The wire passes through the side cover 2 downward through the wire passing hole 212 and is connected to the vehicle controller along the vehicle frame 1.

[0124] The switch assembly is located on the side of the steering hole 33 closer to the vehicle interior. As mentioned above, an active steering assembly is configured in the steering hole 33. As a component with a significantly higher operation frequency than the switch assembly, the component for the user to hold is significantly higher than the side cover 2, so as to avoid accidentally touching the switch assembly when operating the active steering assembly. At the same time, because the active steering assembly is significantly higher than the side cover 2, in some optional embodiments, in the left-right direction of the vehicle, the switch assembly is located on the side of the steering hole 33 closer to the vehicle interior.

[0125] That is, for the embodiment in which the display screen assembly 3 is configured 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 configured on the left side of the vehicle, the switch assembly is located on the right side of the steering hole 33.

[0126] In some optional embodiments, reference appendix Figure 1 appendix Figure 2 , the active steering assembly is a joystick 4 that passes through the steering hole 33 of the display screen assembly and bends towards the middle of the vehicle, and it may also deflect outward. In this embodiment, the switch assembly is configured on the left side of the steering hole 33 to avoid interference between the joystick 4 and the switch assembly when the joystick 4 deflects outward.

[0127] In some optional embodiments, in order to facilitate the user to interact with the vehicle control system through the display screen assembly 3, the display unit 31 of the display screen assembly 3 is configured with buttons for the user to operate. The user can adjust the content displayed on the display unit 31 through the buttons, or send instructions to the vehicle through the buttons, etc.

[0128] In some optional embodiments, it is not suitable for water to enter the display unit 31. Since there are likely to be gaps at the physical buttons in the display unit 31, a waterproof component for preventing water from seeping into the display unit 31 through the gaps of the physical buttons needs to be configured at the buttons. Refer to the attached Figure 19 , and the button of the display unit 31 in the figure is marked as "key body 3111".

[0129] 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. A flexible seal 3112 is configured at the keyhole 3211. The first housing 321 and the display unit 31 jointly press the seal 3112 to form a sealed space that wraps the button, so that external water cannot enter the display unit 31 through the gap. That is, it enables the display screen assembly to maintain a normal working state in a rainy environment. The vehicle can be configured with the display screen assembly in this embodiment and work normally in a rainy environment.

[0130] For the sake of lightweight and cost savings of materials, the first housing 321 is generally made of plastic and fixed to the display unit 31 by bolts. In some embodiments, in order to enhance the effect of user-vehicle interaction through buttons, generally two or more buttons are configured, and each button is provided with a keyhole 3211 and a seal 3112. For a relatively small display unit 31, the seal 3112 can still maintain an effective sealing effect through the bolts at the edge; however, for a relatively large display unit 31, it is difficult for the plastic first housing 321 to maintain a large rigidity at its central position, resulting in a slightly smaller pressing force on the seal 3112 and thus unable to effectively meet the sealing effect.

[0131] Therefore, in some optional embodiments, refer to the attached Figure 18 , the display unit 31 is provided with at least two buttons at intervals. The first housing 321 is configured with at least two keyholes 3211. A bolt is configured 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 the bolts in other positions, the bolts here will be uniformly referred to as "sealing bolts 3113" below. This is only a naming 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 press the seal 3112 can be selected here.

[0132] The sealing bolt 3113 connects the first housing 321 to the display unit 31 and presses the seal 3112. The sealing bolt 3113 and the bolts that cooperate with the first housing 321 at the edge of the display unit 31 jointly achieve the sealing effect at the seal 3112. Specifically, the presence of the sealing bolt 3113 improves the rigidity of the first housing 321 at the seal 3112, so that the first housing 321 can be in close contact with the display housing 32, and further enables the contact between the seal 3112 and the display housing 32 to achieve effective sealing, that is, an effective sealed space can be generated, achieving the technical effect of waterproofing.

[0133] In some alternative embodiments, referring to the attached Figure 18 , five keyholes 3211 are linearly arranged in the first housing 321 in the figure. The first housing 321 is provided with four sealing holes 3212. The sealing bolt 3113 passes through the sealing holes 3212 and is threadedly connected to the display unit 31. Two of the 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: the first sealing hole 3212, the first keyhole 3211, the second keyhole 3211, the second sealing hole 3212, the third keyhole 3211, the third sealing hole 3212, the fourth keyhole 3211, the fifth keyhole 3211, the 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 to enable the seal 3112 to effectively complete the sealing of the buttons, at least one sealing hole 3212 is located between two keyholes 3211 to meet the requirement that after the first housing 321 with a larger area cooperates with the display unit 31, the seal 3112 at the keyholes 3211 can effectively seal the buttons.

[0134] In another part of the alternative embodiments, the first housing 321 is not provided with the above-mentioned sealing holes 3212, but through holes are provided in the display unit 31, and internal threads are provided in the first housing 321. The sealing bolt 3113 passes through the through holes of the display unit 31 and is threadedly connected to the internal threads of the first housing 321, thereby pressing the seal 3112 to achieve the sealing effect. The sealing bolt 3113 of this embodiment is not directly exposed to the outside, which not only makes the outer shell of the first housing 321 look more concise, but also can avoid the phenomenon of rust caused by the sealing bolt 3113 contacting rainwater.

[0135] In some alternative embodiments, referring to the attached Figure 7 , attached Figure 20, the display unit 31 further includes a screen disposed obliquely, and the display housing 32 is configured with a screen hole for exposing the screen outward. For some embodiments, it is difficult to keep the lower edge 3213 of the contact portion between the display unit 31 and the screen hole completely sealed, that is, water leakage may occur at this connection. Therefore, a diversion groove 3114 is provided on the lower side of the outer wall of the screen of 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 diversion groove 3114. Refer to the appendix Figure 13 , the bottom of the second housing 322 is configured 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 configured in the figure, and smooth drainage can be maintained when one of the drain holes 3221 is blocked.

[0136] In some alternative embodiments, the display unit 31 is configured with a touch screen that can be touched and manipulated by the user. Therefore, the screen hole should be a through hole and no transparent glass layer that affects the touch operation is configured.

[0137] In some alternative embodiments, refer to the appendix Figure 14 , a signal line hole 36 is provided on the side of the display unit 31 away from the first housing 321. A wire (not shown) connecting the screen and the riding mower passes through the signal line hole 36, and the signal line hole 36 is coated with a sealant (not shown).

[0138] In some alternative embodiments, the multi-functional work vehicle further includes a passive wheel 8 and a seat 5; the passive wheel 8 is disposed at the front of the vehicle frame 1 on one side of the display screen assembly 3; for carrying the user; at least part of the passive wheel 8 is visible to the driver sitting on the seat 5 without being blocked by the display screen assembly 3. Refer to the appendix Figure 1 , appendix Figure 2 , the multi-functional work vehicle shown in the figure includes two universal wheels, and one of the universal wheels is located at the front on one side of the display screen assembly 3, that is, the aforementioned passive wheel 8.

[0139] The driven wheel 8 is not blocked by the display screen and is in a visible state to the user. When the user is driving a vehicle and performing operations, the edge of the operation area can be judged through the driven wheel 8, so that problems such as omission will not occur during the operation. Specifically, in some alternative embodiments, the aforementioned outdoor operation component is a cutting table 6 equipped with a cutter, and the multi-functional operation vehicle at this time is a lawn mower. When the user is driving the lawn mower to mow the grass, it is necessary to drive back and forth in a zigzag pattern, and generally control that there is a small overlap between the current mowing area and the mowed area during the straight driving process to avoid missed grass. Therefore, the user needs to know at all times whether the current mowing range meets the expectations. In this embodiment, a part of the driven wheel 8 is not blocked and is in a visible state, and the line of sight of the user when looking at the driven wheel 8 is similar to the line of sight when looking at the display screen assembly 3. Therefore, the user can switch very quickly between looking at the driven wheel 8 and looking at the display screen assembly 3; and when looking at the contour of the driven wheel 8, the contour can be compared with the mowed area on the ground, and the relative position relationship between the current mowing area and the mowed area can be known according to the user's experience. If there is no overlap or the overlap range is too large between the current mowing area and the mowed area, the vehicle orientation should be adjusted through the active steering component until there is a small overlap between the current mowing area and the mowed area.

[0140] That is, the display screen assembly 3 does not block or does not completely block the user's view of the driven wheel 8, so that the user can judge whether the position and angle of the vehicle are appropriate through the position relationship between the driven wheel 8 and the mowed area. When looking at the driven wheel 8, the user's peripheral vision can also clearly notice the content change of the display screen assembly 3. If there is an alarm or other information reminder on the display screen assembly 3, it will also be known by the user more timely.

[0141] In some alternative 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 at the user's head. For the convenience of description and understanding, the following definitions are made: 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.

[0142] For the sake of riding safety and comfort, the seat 5 includes a seat cushion and a backrest. The connection line between the center of the top of the seat 5 and the center of the display unit 31 is the first straight line. The included angle between the projection of the first straight line in the first plane and the first direction is less than or equal to 40°. Refer to the attached Figure 21 , the straight line a in the figure is the projection of the first straight line in the first plane, and the straight line b is parallel to the first direction, that is, the included angle α between the straight line a and the straight line b ≤ 40°; the included 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 22 , the straight line c in the figure is the projection of the first straight line in the second plane, and the straight line d is parallel to the first direction, then the included angle β between the straight line c and the straight line d ≤ 50°.

[0143] The component of the entire vehicle closest to the user's head is the backrest of seat 5. Therefore, the line connecting the center of the top of 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 in the first direction straight ahead. Therefore, the angles between the projection of the above-mentioned first line in the first plane and the first direction, and the projection of the first line in the second plane and the first direction can be used to represent the deflection angle of the line of sight when the user needs to look at the display screen. The above 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.

[0144] In some alternative embodiments, the angle between the projection of the first line in the first plane and the first direction is greater than or equal to 20° and less than or equal to 40°. In addition, in some alternative embodiments, the angle between the projection of the first line in the second plane and the first direction is greater than 30° and less than or equal to 50°. That is to say, the display screen is significantly located obliquely below seat 5, avoiding the display unit 31 from blocking the view ahead of the vehicle and affecting outdoor operations.

[0145] In some alternative embodiments, it is further defined that: the line passing through the center of the display unit 31 and perpendicular to the plane of the display unit 31 is the second line.

[0146] In some alternative embodiments, the angle between the projection of the second line in the first plane and the first direction is greater than or equal to 5° and less than or equal to 25°. Refer to the attached Figure 23 , which shows a top view of a part of the side cover 2. The line e is the projection of the second line in the first plane, and the line f is parallel to the first line. Then the value range of the angle δ between the line e and the line f in the attached figure is 25° ≥ δ ≥ 5°, that is, from the perspective of the top view of the display unit 31, it is inclined to one side of seat 5 to a certain extent.

[0147] The angle between the projection of the second line in the second plane and the first direction is greater than or equal to 40° and less than or equal to 65°. Refer to the attached Figure 24 , which shows a side view of a part of the side cover 2. The line g is the projection of the second line in the second plane, and the line h is parallel to the first line. Then the value range of the angle ε between the line g and the line h in the attached figure is 65° ≥ ε ≥ 40°, that is, from the perspective of the side view of the display unit 31, it is inclined upward to a certain extent.

[0148] The above two angles, δ and ε, represent the orientation of the display unit 31, specifically the orientation of the screen portion on the display unit 31, which mainly affects whether it faces the user's face or the degree to which its orientation deviates from the user's face. In some alternative 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°; in addition, in some alternative 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°, 60° ≥ ε ≥ 50°. Within this angular range, the user sitting on the seat 5 can relatively clearly see the information displayed by the display unit 31.

[0149] In some alternative embodiments, on the side of the display unit 31 close to 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 inclined towards directly above or obliquely above the seat 5; since the first straight line and the second straight line have an intersection point located on the display unit 31, the first straight line and the second straight line are coplanar and have an included angle, and the included 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 when sitting on the seat 5, the user's head is higher than the top of the seat 5, so the display unit 31 being inclined towards directly above or obliquely above the seat 5 means it is closer to facing the user's eyes, making it more convenient for the user to clearly see the information of the display unit 31.

[0150] In some alternative embodiments, the included 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 is sitting on the seat 5, the user's eyes are within this angular range, enabling the user to more clearly see the information of the display unit 31.

[0151] In some alternative embodiments, the maximum viewing angle of the display unit 31 is 40° - 70°. That is, the line of sight with an angle less than the above maximum viewing angle range with respect to the normal line of the plane of the display unit 31 can effectively see the content displayed by the display unit 31.

[0152] In some alternative embodiments, 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 450mm - 750mm, that is, Figure 21 the value of X is 450mm - 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 - 650mm. This range conforms to the arm length range of normal adults, and the user can touch the display unit 31 by stretching out the arm or leaning forward slightly, that is, the above distance range is significantly more in line with ergonomics.

[0153] In some alternative embodiments, the present specification also discloses a multi-functional work vehicle, which includes the frame 1, a user platform, outdoor work components, drive wheels 7, side covers 2, a display screen assembly 3, and an active steering assembly as described above. The frame 1 extends in a first direction, which is also the front-rear direction of the vehicle; the user platform is disposed on the frame 1 and is used to carry the user; the outdoor work components are disposed on the frame 1 and are 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 to travel; the side covers 2 are disposed on the frame 1, and the side covers 2 are located on the left side and / or the 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 pattern 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 change of the drive wheels 7 on at least one side of the vehicle.

[0154] In some alternative embodiments, the orthographic projections of the active steering assembly, the display screen assembly 3, the side covers 2, and the frame 1 on the ground at least partially overlap. That is, the horizontal distances between the active steering assembly, the display screen assembly 3, and the side covers 2 are small. When the user looks at the active steering assembly, the peripheral vision of the eyes can see the content of the display screen. That is, when the user is operating, the user can timely obtain the state information of the vehicle through the display unit 31, thereby improving the safety of the vehicle.

[0155] In some alternative embodiments, the display screen assembly 3 is further provided with a switch assembly, that is, a switch assembly is provided for the connection part of the display screen 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 to drive the vehicle, the user should operate the vehicle switch 34 to make the vehicle in a powered-on state, and then control the vehicle to work through components such as the active steering assembly. The work component control switch 35 is used to control the start or stop of the outdoor work components when the vehicle is in a powered-on state. When the vehicle travels to the work location, the outdoor work components are controlled to start or stop through the work component control switch 35 to perform work on the area to be worked.

[0156] In some alternative embodiments, the display screen assembly 3 includes a display unit 31 and a display housing 32 that at least wraps part of the display. The active steering assembly and / or the vehicle master switch 34 and / or the working component control switch 35 are located on a side closer to the rear of the vehicle relative to the display unit 31. That is, the active steering assembly and / or the vehicle master switch 34 and / or the working component control switch 35 are located on a side closer to the user relative to the display unit 31, facilitating the user's manual operation of the active steering assembly and / or the vehicle master switch 34 and / or the working component control switch 35. Since the distance between the active steering assembly and / or the vehicle master switch 34 and / or the working component control switch 35 and the display unit 31 is relatively close, when the user looks at and operates the active steering assembly and / or the vehicle master switch 34 and / or the working component control switch 35, the user's peripheral vision can observe the content displayed by the display unit 31. That is, the user can timely obtain the vehicle status information through the display unit 31 during operation, thereby improving the safety of the vehicle.

[0157] In some alternative embodiments, referring to the attached Figure 25 , the display unit 31 includes at least one button for the user to operate. The distance between at least one of the buttons and the vehicle master switch 34 or the working component control switch 35 in the first direction is 20 mm to 100 mm, that is, the range of Y in the attached drawing is 20 mm to 100 mm. As described above, the close distance between the display unit 31 and the vehicle master switch 34 or the working component control switch 35 facilitates the user to obtain the vehicle status information. However, when the user operates the vehicle master switch 34 or the working component control switch 35, the display unit 31 should not interfere with the user's hand, that is, the display unit 31 should not block the user's hand from operating the vehicle master switch 34 or the working component control switch 35. The above distance less than or equal to 100 mm in the first direction meets the space for the user's hand movement. In some embodiments, the buttons of the display unit 31 are misaligned with the vehicle master switch 34 or the working component control switch 35 in the left-right direction of the vehicle. Therefore, appropriately shortening the distance between the button and the vehicle master switch 34 or the working component control switch 35 in the first direction will not cause interference. However, for convenience of layout, there is still a need to configure a 20-mm distance between the button and the vehicle master switch 34 or the working component control switch 35 in the first direction. In summary, that is: the distance between at least one of the buttons and the vehicle master switch 34 or the working component control switch 35 in the first direction is 20 mm to 100 mm.

[0158] In some alternative embodiments, the seat 5 carrying the user includes a seat cushion and a backrest. The distance between at least one of the buttons and the center of the top of the backrest in the first direction is 420 mm to 720 mm. In another more specific embodiment, the distance between the center of the top of the seat 5 and at least one of the buttons in the first direction is 550 mm to 650 mm. This range conforms to the arm length range of normal adults, and the user can operate the buttons by stretching out their arm or leaning forward slightly, that is, the above distance range is significantly more ergonomic.

[0159] In some alternative embodiments, refer to Appendix Figure 1 , Appendix Figure 2 , the multi-functional work vehicle only includes one display screen assembly 3, and one of the active steering assemblies 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.

[0160] As described above, the multi-functional work vehicle includes two active steering assemblies, and when the active steering assemblies move forward and backward, they control the rotational speed change of the corresponding drive wheels 7. 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 part and a connecting part, and the steering hole 33 is arranged in the connecting part. The display screen assembly 3 is relatively close to the corresponding active steering assembly, so that the user can more conveniently see the information displayed by the display screen assembly 3 when looking at the active steering assembly.

[0161] In some more specific embodiments, when the active steering assembly moves forward, it controls the corresponding drive wheel 7 to rotate forward, and when the active steering assembly moves backward, it controls the corresponding drive wheel 7 to rotate backward. Moreover, the greater the movement amount of the active steering assembly, the faster the rotational speed of the corresponding drive wheel 7. When the rotational speeds of the two drive wheels 7 on both sides are not equal, the vehicle will turn. Therefore, the two active steering assemblies control the forward and backward driving and turning of the vehicle through their movement amounts.

[0162] In some more specific embodiments, the active steering assembly can also move in the left-right direction. Specifically, refer to Appendix Figure 5 , Appendix Figure 7 , after the right active steering assembly moves to the right, it is limited by the steering hole 33 and cannot move in the front-back direction anymore. After the left active steering assembly moves to the left, it cannot move in the front-back direction anymore; and when the right active steering assembly moves to the right or the left active steering assembly moves to the left, the vehicle will enter the parking state, and the vehicle in the parking state needs to be unlocked to control the rotation of the drive wheel 7.

[0163] In some alternative embodiments, refer to Appendix Figure 1 , Appendix Figure 2, the display screen assembly 3 is arranged on the right side of the vehicle. The corresponding steering hole 33 is configured as a T-shaped hole (the T is placed horizontally) through which the active steering assembly can move to the right when it moves to the middle position in the front-rear 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.

[0164] In some more specific embodiments, for the user carried on the user platform, when the active steering assembly moves to the right and the vehicle enters the parking state, the display unit 31 is visible without being blocked by the active steering assembly. The wheels do not rotate in the parking state, that is, the wheels are in a safe state. In this state, the display unit 31 should be freely controlled by the user. Therefore, it should be set that the active steering assembly does not block the display unit 31.

[0165] In some alternative embodiments, when the active steering assembly moves to the left and can move back and forth along the steering hole 33, the display unit 31 is partially blocked by the active steering assembly and is not completely visible. Because when the active steering assembly is in a state where it can move back and forth along the steering hole 33 and the vehicle is in a non-parking state, the vehicle may be moving or is moving and has a certain degree of danger. At this time, the display unit 31 should only be a display component. It is not appropriate for the user to remove their hand from the active steering assembly and touch the display unit 31. Therefore, it is set that the active steering assembly blocks the display unit 31. Even if the user releases the active steering assembly, their hand will necessarily be blocked by the active steering assembly and it is not easy to touch the display unit 31. That is, it forces the user to control the active steering assembly to move to the right and the vehicle enters the parking state so that the vehicle is relatively safe for the user to easily touch the display unit 31.

[0166] In some more specific embodiments, the display screen assembly 3 does not significantly protrude upward from the highest point of the side covering member 2. That is, the height of the display screen assembly 3 is roughly equivalent to or lower than that of the corresponding side covering member 2. As described above, the display unit 31 of the display screen assembly 3 protrudes forward from the side covering member 2. The purpose of controlling the display screen assembly 3 not to significantly protrude upward in this embodiment is to reduce the probability of it colliding with external objects. When external objects may impact the vehicle in this embodiment laterally, it is more likely that the side covering member 2 bears the impact force to avoid damage to the display screen assembly 3 and prevent damage to this relatively fragile component of the display screen assembly 3 from causing greater economic losses.

[0167] In some alternative embodiments, referring to the attached Figure 1 attachment Figure 6, the side cover 2 is provided with a height adjustment groove 205, and a height adjustment rod 10 that is operably rotatably connected to the vehicle frame 1 penetrates through the height adjustment groove 205. 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 work. The height adjustment rod 10 is located on the side closer to the rear of the vehicle relative to the display screen assembly 3. Since the weight of the outdoor working component may be relatively large, the height adjustment rod 10 being more rearward means it is closer to the user, facilitating the user to exert force to adjust the height of the outdoor working component.

[0168] In some alternative embodiments, refer to the attached Figure 4 , the vehicle frame 1 includes a main frame body and a bridging member 101 fixed to the main frame body. The bridging member 101 is a connecting member made of metal, which is used to assist in installing the side cover 2, the display housing 32, etc., and can be regarded as a part of the vehicle frame 1. Further, in this embodiment, the display housing 32, the side cover 2, and the bridging member 101 are all provided with steering holes 33 for the active steering assembly to pass through.

[0169] In some alternative embodiments, the multi-functional work 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 through wires. 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 wires to pass through. Refer to the attached Figure 6 .

[0170] In some alternative embodiments, refer to the attached Figure 7 , the display housing 32 includes a connection part for configuring the active steering assembly and / or the vehicle switch 34 and / or the working component control switch 35, and a display part whose extending direction is different from that of the connection part; the display unit 31 is arranged on the display part. The display part and the connection part form an angle such that the display unit 31 faces the user's head, thus facilitating the user to view.

[0178] In some alternative embodiments, the display unit 31 includes buttons that can be manipulated by the user, that is, the user can interact with the display unit 31 through the buttons. The display housing 32 includes a first housing 321 and a second housing 322. At least two keyholes 3211 for the buttons to pass through are spaced apart on the first housing 321. A flexible seal 3112 is disposed at the keyholes 3211. A sealing hole 3212 is disposed between at least two of the keyholes 3211 of the first housing 321. A bolt for fastening the first housing 321 to the display unit 31 and squeezing the seal 3112 is disposed in the sealing hole 3212.

[0179] In some other alternative embodiments, this specification also discloses a multi-functional work vehicle, which includes the frame 1, outdoor work components, side covers 2, and a display screen assembly 3 as described above. The frame 1 extends in a first direction, which is the front-rear direction of the vehicle; the outdoor work components are disposed on the frame 1 and are used to perform outdoor work; the side covers 2 are disposed on the left side and / or the 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.

[0180] In some alternative embodiments, referring to the attached Figure 3 , the display housing 32 of the multi-functional work vehicle includes a connecting portion that is nearly horizontally connected to the side cover 2 and a display portion whose extending direction is different from that of the connecting portion. The display screen assembly 3 includes a display unit 31 disposed on the display portion and used to display pattern or character information. That is, the display screen assembly 3 includes two parts with different extending directions, and the connecting portion is in contact with the side cover 2 and remains in a substantially horizontal state, and the display portion is inclined towards the user's face, so as to prevent the user from having to significantly turn the head downward to see the information of the display unit 31.

[0181] It should be specifically noted that the "nearly horizontal" of the foregoing connecting portion should be understood as having a small angle with the horizontal direction. For example, within the range of ±15° from the horizontal direction, it should be understood as the foregoing nearly horizontal. Because within this angle range, the naked eye cannot obviously observe that it is in a non-horizontal state.

[0182] In some alternative embodiments, referring to the attached Figure 1 、attached Figure 2, the multi-functional work vehicle further includes a user platform for carrying a user. The normal line of the plane where 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 where the display unit 31 displays the pattern is also the surface where the screen of the display unit 31 is located. Therefore, the vertical line of the surface where the screen of the display unit 31 is located points directly above the user platform, facilitating the user to clearly see the information displayed by the display unit 31.

[0183] In another part of the optional embodiments, refer to the attached Figure 1 , attached Figure 2 , a multi-functional work vehicle is also disclosed. The multi-functional work vehicle includes a vehicle frame 1, outdoor work components, side covers 2, and a display screen assembly 3. The vehicle frame 1 extends in a first direction, which is the front-rear direction of the vehicle; the outdoor work components are configured on the vehicle frame 1 and are used to perform outdoor work; the side covers 2 are configured on the vehicle frame 1 and are located on the left side and / or the right side of the vehicle; the display screen assembly 3 is configured on the side covers 2 and is used to display patterns or character information to the user.

[0184] In a part of the optional embodiments, refer to the attached Figure 1 , attached Figure 2 , the display screen assembly 3 includes a connecting portion that is nearly horizontally connected to the side cover 2 and a display portion whose extending direction is different from that of the connecting portion. The display screen assembly 3 includes a display unit 31 that is configured on the display portion and is used to display patterns or character information. Specifically, the side cover 2 includes a nearly horizontal assembly surface 206, and the display screen assembly 3 includes a first surface 37 that is used to cooperate with the assembly surface 206. The purpose of the first surface 37 and the assembly surface 206 being nearly horizontal is that during the assembly process of the two, when the display screen assembly 3 is placed on the assembly surface 206, the display screen assembly will not slide and shift due to the action of its weight, facilitating the assembly.

[0185] In this embodiment, the extending direction of the display portion is different from that of the connecting portion because the display portion is mainly used to display patterns or character information to the user through the display unit 31; as described above, the connecting portion extends in the horizontal direction, so the plane of the connecting portion faces directly upward. If the user looks at the connecting portion, they need to lower their heads so that their line of sight is vertically downward to clearly see the characters on the surface of the connecting portion. The extending direction of the display portion being different from that of the connecting portion means that the display unit 31 is inclined relative to the horizontal plane, so that the user can see the content displayed by the display unit 31 without significantly lowering their heads.

[0186] In some alternative embodiments, the multi-functional work vehicle includes a user platform for carrying a user, and the normal line of the plane where the display unit 31 displays a pattern points directly above the user platform. When the user is carried on the user platform, the user's head is naturally located directly above the user platform. In this embodiment, it is controlled that the normal line of the plane where the display unit 31 displays a pattern points directly above the user platform, that is, nearly points to the user's head, so as to facilitate the user to view the pattern or character information displayed by the display unit 31. In some alternative embodiments, the component of the display unit 31 for displaying a pattern is a screen, and the above-mentioned plane for displaying a pattern is the screen surface.

[0187] In some alternative embodiments, the connecting portion is configured with a switch assembly, and the switch assembly includes a vehicle-wide switch 34 and / or an operation component control switch 35; the vehicle-wide switch 34 is used to control whether the multi-functional work vehicle is in a powered-on state; the operation component control switch 35 is used to control the start or stop of the outdoor operation components when the vehicle is in a powered-on state. That is, the switch assembly and the display unit 31 are both located at 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 state of the vehicle, the user can conveniently gaze at the information displayed by the display unit 31 to confirm whether the vehicle state meets the user's expectations.

[0188] In some alternative embodiments, the multi-functional work vehicle further includes drive wheels 7 and an active steering device; the drive wheels 7 are arranged on the left and right sides of the vehicle frame 1 and are used to drive the vehicle to travel; the active steering device is operably rotatably connected to the left side and / or the right side of the vehicle frame 1 and is used to cause a speed difference between the drive wheels 7 on both sides to make the vehicle turn.

[0189] In some alternative embodiments, at least one of the active steering components penetrates 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.

[0190] In some alternative embodiments, the display housing 32 is provided with a steering hole 33 penetrated by the active steering component. When the active steering component is operated by the user to move forward or backward in the steering hole 33, it controls the speed change of at least one side of the drive wheels 7. 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-rear direction. That is, the active steering component does not interfere with the side wall of the steering hole 33 when moving forward, backward, or to the right.

[0191] In some more specific embodiments, for the users carried by the user platform, when the active steering component moves to the right to put the vehicle into the parking state, the display unit 31 is not blocked by the active steering component and is visible. The wheels do not rotate in the parking state, that is, the wheels are in a safe state. In this state, the display unit 31 should be freely controllable by the user. Therefore, it should be set that the active steering component does not block the display unit 31.

[0192] In some alternative embodiments, the display unit 31 includes a touch screen that can be touched by the user. The user can complete the signal input to the display unit 31 through touching, so as to control the state of the vehicle.

[0193] In some alternative embodiments, when the active steering component moves to the left and can move back and forth along the steering hole 33, a part of the display unit 31 is blocked by the active steering component and is not completely visible. Because when the active steering component can move back and forth along the steering hole 33 and the vehicle is in a non-parking state, the vehicle may be moving or is moving and has a certain degree of danger. At this time, the display unit 31 should only be a display component. The user should not take his hand off the active steering component and touch the display unit 31. Therefore, it is set that the active steering component blocks the display unit 31. Even if the user releases the active steering component, his hand will necessarily be blocked by the active steering component and it is not easy to touch the display unit 31. That is, it forces the user to control the active steering component to move to the right to put the vehicle into the parking state, and the vehicle can be relatively safe for the user to easily touch the display unit 31.

[0194] In some other alternative embodiments, a riding mower is also disclosed. The riding mower includes the frame 1, the outdoor operation component, the side cover 2 and the display screen assembly 3 as described above; the frame 1 extends substantially along the first direction, and the outdoor operation component is configured to be assembled to the frame 1 and is a cutting table 6 for performing mowing operations. The side cover 2 is configured on the frame 1, and the side cover 2 is located on the left side and / or the right side of the vehicle. The display screen assembly 3 is configured on the side cover 2 and is used to display pattern or character information for the user. The display screen assembly 3 includes a connecting portion that is nearly horizontally connected to the side cover 2 and a display portion whose extending direction is different from that of the connecting portion. The display screen assembly 3 includes a display unit 31 configured on the display portion and used to display pattern or character information.

[0195] In another alternative embodiment, a riding mower is also disclosed, which includes the frame 1, outdoor operation components, side covers 2, a power system, and a display screen assembly 3 as described above; the frame 1 extends substantially along a first direction, and the outdoor operation components are configured to be assembled to the frame 1 and include a cutting table 6 for performing mowing operations. The side covers 2 are configured on the frame 1, and the side covers 2 are located on the left side and / or the 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. The power system is used to supply power to the outdoor operation components and the display screen assembly 3. The display screen assembly 3 includes a connecting portion that is nearly horizontally connected to the side covers 2 and a display portion whose extending direction is different from that of the connecting portion, and the display screen assembly 3 includes a display unit 31 configured on the display portion and used to display pattern or character information.

[0196] In another alternative embodiment, a multi-functional operation vehicle is also disclosed. The multi-functional operation vehicle includes a frame 1, outdoor operation components, side covers 2, and a display screen assembly 3. The frame 1 extends along a first direction, and the first direction is the front-rear direction of the vehicle; the outdoor operation components are configured on the frame 1 and are used to perform outdoor operations; the side covers 2 are configured on the frame 1 and are located on the left side and / or the 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. The display screen assembly 3 includes a screen with an area of not less than 80 cm 2 . 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 the user can more easily distinguish the information displayed on the screen and improve the practicality of the screen. In addition, because the screen is large and 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 operations based on the more information obtained. For example, the user can simultaneously obtain information such as the remaining battery range, the remaining area to be operated, the time, or the weather conditions in the next few hours within one interface of the screen, and then make the best decision on whether to continue operating, etc.

[0197] In some alternative embodiments, the area S of the screen of the display screen assembly 3 is greater than or equal to 100 cm 2 . In other alternative embodiments, the area S of the screen of the display screen assembly 3 is greater than or equal to 120 cm 2。As mentioned above, a larger screen can display more information. Therefore, within the allowable space, the larger the screen, the more conducive it is to display information to users. In some alternative embodiments, the diagonal size of the screen of the display screen assembly 3 is greater than or equal to 6 inches. Further, in some alternative embodiments, the size of the screen is 6.75 inches, and the aspect ratio is 16:9, then the area of the screen is approximately 126 cm 2 , which better meets the needs of users. In some other alternative embodiments, the size of the screen is 8 or 10 inches, and the aspect ratio is 16:9. Among them, the area of the 8-inch screen is approximately 176 cm 2 , and the area of the 10-inch screen is approximately 276 cm 2 . In other embodiments, various aspect ratios such as 4:3 or 16:10 of the screen can also be selected, which should not be construed as breaking through the protection scope of this embodiment and will not be elaborated here.

[0198] In some alternative embodiments, the dots per inch (DPI) of the screen of the display screen assembly 3 is greater than or equal to 120, which refers to the number of samples, displayable, or output points per inch of length. That is, 120×120 = 14,400 pixel points are output per square inch of the screen in this embodiment. Therefore, the larger the dots per inch of the screen, the clearer the content displayed. The dots per inch (DPI) of the screen of the display screen assembly 3 in this embodiment being greater than or equal to 120 can meet the needs of users in most cases.

[0199] In some alternative embodiments, the multi-functional work vehicle further includes a seat 5, drive wheels 7, and an active steering device.

The plurality of battery units can select at least one of a first specification battery pack and a second specification battery pack. The specification differences between the first specification battery pack and the second specification battery pack include, but are not limited to, differences in battery pack capacity, voltage, battery internal resistance, weight, size, energy density, cell type, charge information, battery health status information, etc.

[0207] In some alternative embodiments, the difference between the first specification battery pack and the second specification battery pack lies in the different battery pack capacities. The capacity of the first specification battery pack is greater than that of the second specification battery pack. The second specification battery pack is configured to provide power for handheld gardening tools. For example, the second specification battery pack can supply power to garden tools such as lawn trimmers, pruning shears, leaf blowers, and chain saws. In addition, the second specification battery pack can also supply power to torque output tools such as electric drills and hammers; supply power to sawing tools such as circular saws, jigsaws, and reciprocating saws, or supply power to grinding tools such as angle grinders and sanders.

[0208] In some alternative embodiments, the difference between the first specification battery pack and the second specification battery pack lies in the different cell types selected. For example, the first specification battery pack and the second specification battery pack can select lithium iron phosphate cells and ternary lithium cells respectively. The plurality of battery units in the power supply system can also select nickel-chromium battery cells, lead-acid battery cells, graphene cells, etc.

[0209] The plurality of battery units of the power supply system select at least one of a first specification battery pack and a second specification battery pack. Such a method enables the multi-functional vehicle to be compatible with different specification battery packs, meeting the high-power work requirements and being able to adapt to handheld electric gardening tools at the same time, making the working methods of garden workers more flexible.

[0210] In one alternative embodiment, the power supply system further includes a battery compartment 9, a battery management system, etc. The battery compartment 9 is used to accommodate the battery pack, and the battery management system is used to manage the power supply of the battery pack to each component of the vehicle.

The battery pack is detachably configured in the battery compartment 9 to enable the detachable replacement of the battery pack, and the removed battery pack can be used for the above-mentioned other electric gardening tools; and the design of the detachable battery pack enables the vehicle to quickly return to a workable state by simply replacing the battery pack without waiting for a long charging time when the battery power of the vehicle is low or exhausted.

[0212] In one alternative embodiment, the battery compartment 9 is detachably configured on the vehicle frame 1, and the battery pack is accommodated in the battery compartment 9, that is, the battery compartment 9 can be separated from or combined with the vehicle frame 1 as a whole.

[0213] In some alternative embodiments, the outdoor operation component is implemented as a cutting table 6, and the multi-functional operation vehicle in this embodiment is a lawn mower; in addition, if the outdoor operation component is a snow sweeping component, then the multi-functional operation vehicle is a snow sweeper; that is, the outdoor operation component, as the main functional component of the multi-functional operation vehicle, can be changed according to the user's choice; at the same time, in some embodiments, the above-mentioned outdoor operation component can also be a component that the user replaces according to actual needs. For example, if the cutting table 6 for mowing is removed and replaced with a sweeping disc for sweeping, then the lawn mower is changed to a sweeper. In summary: Replacing the outdoor operation component with any functional component according to the user's needs should not be understood as exceeding the protection scope of this embodiment.

[0214] As mentioned above, the operation vehicle equipped with a power supply system is a rechargeable operation vehicle. The rechargeable operation 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 plug, no fuel storage, etc.) compared with traditional fuel-powered operation vehicles. The power system of the rechargeable operation vehicle uses an electric motor instead of a fuel engine, and the electric motors of the drive wheels 7 can be controlled separately to achieve motion control such as straight running, reversing, turning, and zero turning of the whole vehicle, reducing the structural complexity of the whole vehicle and making the control of the whole vehicle more flexible.

[0215] Similarly, the gardening vehicle equipped with a power supply system is a rechargeable gardening vehicle and also has the above-mentioned beneficial effects.

[0216] Referring to the accompanying drawings, the work vehicle shown in the figures is configured with a steering lever. The user manipulates the steering lever to change the rotational speed of the drive wheels 7, thereby driving and controlling the vehicle. In other embodiments, the steering lever can also be changed to a steering wheel structure. That is, the control method of vehicle steering should not be understood as exceeding the protection scope of this embodiment.
