[DETAILED DESCRIPTION]

[0094] The terms used in the present application are merely for the purpose of describing particular embodiments and are not intended to limit the present application. Words such as "upper", "lower", "front", "back", and the like, which indicate spatial or positional relationships based on the orientation or position shown in the drawings, are used only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0095] Unless otherwise specified, the terms "provided", "connected" and "connected" in the present application should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. The "fixed connection" in the present application should also be broadly understood as integrally formed or welded or connected through other fasteners.

[0096] The embodiment discloses a multifunctional work vehicle, referring to FIG. 1, comprising a frame 1, an outdoor work part, and a seat 5; wherein the frame 1 extends along a first direction, which is also the forward direction of the vehicle; the outdoor work part is arranged on the frame 1 and is used for performing outdoor work; and the seat 5 is arranged on the frame 1 and is used for carrying a user.

[0097] In order to make the vehicle more beautiful, the vehicle left and / or right and / or rear cover is generally configured. In one of the alternative embodiments, with reference to Figure 1, the multi-functional working vehicle includes a side cover 2, which is shown on the right side of the vehicle, and the side cover 2 is also configured with a display screen assembly 3, which can show patterns or character information to the user when powered on; in another alternative embodiment, the side cover 2 configured with the display screen can also be configured on the left side of the vehicle. In another alternative embodiment, the left and right sides of the vehicle are both configured with side covers 2, and both sides are configured with display screen assemblies 3 that can show patterns or character information to the user. It should be noted that in order to make the position of the side cover 2 relatively stable, it is fixed to the frame 1 by bolts and other fasteners.

[0098] In one of the alternative embodiments, the seat 5 includes a seat cushion and a backrest for the user to lean on when sitting on the seat cushion. Looking along the center of the top of the backrest towards the front of the vehicle, the vehicle side front outer contour in front of the display screen assembly 3 is visible. This embodiment configures the display screen assembly 3 that can show patterns or character information to the user 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 belongs to the visible state, that is, it will not affect the user to judge the positional relationship between the vehicle and the ground object by observing the vehicle side front outer contour, and will not appear the situation that the driving route is wrong due to the inability to judge the positional relationship between the vehicle.

[0099] It should be noted that the top of the backrest of the seat 5 is the closest entity position to the user's head on the vehicle, so looking along the center of the top of the backrest towards the front of the vehicle is approximately the line of sight of the user sitting on the seat 5 looking towards the front of the vehicle. Therefore, with reference to Figure 2, the vehicle side front outer contour 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, and the shaded part in Figure 2 is the area where the user can see the ground along the side front outer contour of the vehicle. The aforementioned vehicle side front outer contour is the outer contour looking towards the front of the side of the vehicle with the user's head driving the vehicle as the line of sight starting point.

[0100] In the outdoor operation on the ground, the working vehicle will first travel along a straight line, and when it reaches the edge of the working area, it will turn around and travel in the opposite direction of the original direction, and the outdoor working part will slightly overlap the worked area to ensure that there will be no missed working area. In this embodiment, when the above-mentioned 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 working part; but as mentioned 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 working part of the vehicle relative to the user's own looking at the outer contour of the vehicle is unchanged, so the user can determine the overlap degree of the coverage range of the outdoor working part 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, it is the position of the boundary of the worked area in the field of view relative to the outer contour of the vehicle that determines the overlap degree of the coverage range of the outdoor working part and the worked area. Thus, the ground after operation can avoid the emergence of missed working area.

[0101] In some optional embodiments, the multifunctional working vehicle further comprises a passive wheel 8 arranged at the front part of the frame 1 on the side of the display screen assembly 3. Referring to FIG. 1, the multifunctional working vehicle shown in the figure comprises two universal wheels located in front of the vehicle, wherein the universal wheel located on the side of the display screen assembly 3 is the aforementioned passive wheel 8, which is located at the part of the vehicle closest to the front edge.

[0102] In this embodiment, looking forward along the center of the top of the backrest, the passive wheel 8 is at least partially visible without being blocked by the display screen assembly 3, that is, at least part of the passive wheel 8 can be seen by the user sitting on the seat 5, and thus the user can determine the overlap degree of the coverage range of the outdoor working part and the worked area by observing the position of the boundary of the worked area in the field of view relative to the outer contour of the passive wheel 8. Thus, the ground after operation can avoid the emergence of missed working area.

[0103] In some optional embodiments, looking forward along the center of the top of the backrest, part of the passive wheel 8 is blocked by the display screen assembly 3 and is not visible. That is, for the user sitting on the seat 5, the position of the boundary of the worked area in the field of view relative to the outer contour of the display screen assembly 3 can be used to determine the overlap degree of the coverage range of the outdoor working part and the worked area, thereby avoiding the emergence of missed working area on the ground after operation. In this process, when the user determines the working area range, the user can see the information displayed by the display screen assembly 3, and if the information displayed by the display screen assembly 3 changes significantly, it will be very easy for the user to notice, thereby facilitating the user to obtain the vehicle status information from the display screen assembly 3 in time and reducing the danger caused by not obtaining the warning information of the display screen assembly 3 in time.

[0104] In other words, when the user looks at the display screen assembly 3 to obtain the vehicle state information displayed by the display screen assembly 3, the user's side vision can also see the position of the boundary of the worked area in the field of view relative to the outer contour of the display screen assembly 3, so as to determine the overlap degree of the coverage range of the outdoor working component and the worked area. Alternatively, when the user looks at the display screen assembly 3 to obtain the vehicle state information displayed by the display screen assembly 3, the user only needs to adjust the gaze to see the position of the boundary of the worked area in the field of view relative to the outer contour of the display screen assembly 3 without twisting the head, reduces the time required for line-of-sight conversion, and enables the user to concentrate more on driving the vehicle, thereby improving the working safety.

[0105] In some optional embodiments, as shown in FIG. 6, the side cover 2 has a lower side cover portion 201, a rising portion 202, and an upper side cover portion 203 in sequence from front to back of the vehicle, the upper side cover portion 203 is higher than the lower side cover portion 201, and the display screen assembly 3 is arranged on the lower side cover portion 201. That is, the display screen assembly 3 is located on the front side of the side cover 2 to have a relatively obvious distance from the user in the first direction (the front-back direction of the vehicle), and in this embodiment, increasing the distance in the front-back direction can reduce the angle between the line connecting the display screen and the user's eye and the horizontal direction, that is, to avoid the user having to significantly lower the head to see or clearly see the display screen.

[0106] In some optional embodiments, the multi-functional working vehicle further comprises a driving wheel 7 and a main steering assembly. The driving wheel 7 is arranged on the vehicle frame 1 and is driven by a power source arranged on the vehicle frame 1 to rotate as a driving wheel, thereby driving the vehicle to move; the main steering assembly is operatively connected to the left side and / or the right side of the vehicle frame 1 to generate a speed difference between the driving wheels 7 on the two sides to make the vehicle turn; that is, the main 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 the working principles are different, but they can all output torque to the tire to drive the vehicle to move, and the power sources such as internal combustion engines and electric motors are all common prior art, which will not be described here.

[0107] In some optional embodiments, the display screen assembly 3 comprises a display unit 31 and a display housing 32. The display unit 31 can display patterns or character information to display the information of the vehicle to the user when powered on; and the display housing 32 at least covers part of the display unit 31 to fix the display unit 31.

[0108] In some optional embodiments, at least one of the main steering assemblies penetrates 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 main steering assembly.

[0109] In some optional embodiments, the multi-functional work vehicle comprises a main steering component, and the user controls the vehicle to move in the corresponding direction by operating the main steering component to move forward, backward, left or right. The multi-functional work vehicle comprises a display screen component 3, and the main steering component penetrates the display screen component 3, i.e., the distance between the display screen component 3 and the main steering component is relatively short. When the user looks at the display screen component 3 or the main steering component, the other can be clearly seen by the user, thereby reducing the movement of the user's head or eyes when driving the vehicle, reducing the difficulty of driving operation, and indirectly improving the driving safety performance of the vehicle.

[0110] In some optional embodiments, the multi-functional work vehicle comprises two main steering components, and the two main steering components are respectively used to control the rotation of the corresponding drive wheels 7. Referring to FIG. 1 and FIG. 2, the joysticks 4 shown in the figures are the main steering components, and the two joysticks 4 are respectively located on the left side and the right side of the vehicle.

[0111] In some more specific embodiments, the multi-functional work vehicle comprises two display screen components 3 respectively located on the left side and the right side of the vehicle, i.e., the two display screen components 3 are respectively located at the side covers 2 on the left side and the right side of the vehicle, and the two display screen components 3 are respectively used to display different information of the vehicle, such as: one of the display screen components 3 is used to display the speed, remaining power (or fuel), tire pressure, temperature and other information of the vehicle; and the other display screen component 3 is used to display the load degree of the outdoor work component. The two main steering components penetrate the two display screen components 3.

[0112] In some more specific embodiments, referring to FIG. 1, the multi-functional work vehicle comprises a display screen component 3, and one of the main steering components penetrates the display screen component 3. The user only needs to look at one side to obtain the information displayed by the display screen component 3.

[0113] As described above, the multi-functional work vehicle comprises two main steering components, and the main steering components control the speed change of the corresponding drive wheels 7 when moving forward and backward. In some more specific embodiments, referring to FIG. 3, FIG. 4 and FIG. 5, the display screen component 3 is provided with a steering hole 33 for the corresponding main steering component to penetrate. The display screen component 3 comprises a display part and a connecting part, and the steering hole 33 is arranged on the connecting part. The display screen component 3 is relatively close to the corresponding main steering component, so that the user can more conveniently see the information displayed by the display screen component 3 when looking at the main steering component.

[0114] In some more specific embodiments, the forward movement of the active steering assembly controls the corresponding drive wheel 7 to rotate forward, the backward movement of the active steering assembly controls the corresponding drive wheel 7 to rotate backward, and the greater the movement of the active steering assembly, the faster the corresponding drive wheel 7 rotates. When the two drive wheels 7 rotate at different speeds, the vehicle will turn, so the two active steering assemblies control the forward and backward movement of the vehicle and the turning through the movement.

[0115] In some more specific embodiments, the active steering assembly can also move in the left-right direction, specifically, the right active steering assembly cannot move forward and backward after moving to the right, and the left active steering assembly cannot move forward and backward after moving to the left; and the movement of the right active steering assembly to the right or the movement of the left active steering assembly to the left will make the vehicle enter the parking state, and the vehicle in the parking state needs to be unlocked to control the rotation of the drive wheel 7.

[0116] In some more specific embodiments, referring to FIG. 5 and FIG. 7, the steering hole 33 shown in the figure is a T-shaped structure, that is, the active steering assembly does not interfere with the side wall of the steering hole 33 when moving forward and backward or to the right.

[0117] In some more specific embodiments, referring to FIG. 1 and FIG. 6, the upper cover portion 203 is located at least partially above the drive wheel 7, and the upper cover portion 203 is provided with a storage box 204 for storing personal items.

[0118] In some more specific embodiments, referring to FIG. 6, the rising portion 202 is provided with a height adjustment groove 205, and the height adjustment groove 205 penetrates a height adjustment rod 10 operatively connected to the vehicle frame 1, and the rotation of the height adjustment rod 10 drives the change of the ground clearance of the outdoor working component. The height adjustment rod 10, the active steering assembly, and the display screen assembly 3 are relatively commonly used components for users, and they are arranged on the same side of the vehicle to facilitate the user to control the vehicle more conveniently.

[0119] In some more specific embodiments, in order to accurately assemble the display screen assembly 3, referring to FIG. 6, the lower cover portion 201 has an assembly surface 206, and the display screen assembly 3 has a first surface 37 abutting the assembly surface 206, that is, the lower cover portion and the display screen assembly 3 are in surface contact, which has a relatively large contact area. When the vehicle bounces, the extrusion force between the display screen assembly 3 and the lower cover portion can be dispersed to various parts of the contact surface through relative movement, avoiding stress concentration and causing assembly failure.

[0120] In some embodiments, the display assembly 3 has at least two surfaces in contact with the side cover 2 to make the connection more stable. In some embodiments, a reinforcing rib is arranged at the contact position between the side cover 2 and the display assembly 3 to make the contact position more stable.

[0121] In some embodiments, the display assembly 3 has a second surface 38 different from the first surface 37. The lower side cover 201 has a limiting hole 207 through which the display assembly 3 passes. The second surface 38 is in contact with one of the inner walls of the limiting hole 207. The inner wall of the limiting hole 207 in contact with the second surface 38 is provided with a reinforcing rib. The first surface 37 and the second surface 38 are located on opposite sides of the display assembly 3. In the drawings, the first surface 37 is located on the lower side of the display assembly 3, and the second surface 38 is located on the upper side of the display assembly 3. The reinforcing rib at the limiting hole 207 extends at least partially along the extension direction of the inner wall of the limiting hole 207. The reinforcing rib increases the strength of the corresponding inner wall of the limiting hole 207 to prevent the inner wall from being damaged due to the concentrated force.

[0122] In some embodiments, the side cover 2 has an assembly surface 206 and a limiting hole 207. The display assembly 3 has a first surface 37 and a second surface 38. The first surface 37 is in contact with the assembly surface 206. The second surface 38 is in contact with one of the inner walls of the limiting hole 207. The inner wall of the limiting hole 207 in contact with the second surface 38 is provided with a reinforcing rib. In some embodiments, the display assembly 3 is partially inserted into the limiting hole 207. One of the inner walls of the limiting hole 207 is coplanar with the assembly surface 206. The other inner wall of the limiting hole 207 is opposite to the assembly surface 206 and in contact with the display assembly 3. The inner wall of the limiting hole 207 opposite to the assembly surface 206 is provided with a reinforcing rib.

[0123] In some optional embodiments, at least two inner walls of the limiting hole 207 are in contact with the display assembly 3. One of the inner walls is coplanar with the assembly surface 206. The assembly surface 206 has a large area and can withstand relatively large contact force. The other inner wall has a small area, and therefore a reinforcing rib is arranged to increase the strength of the corresponding position to prevent the display assembly 3 from generating large pressure on the position during vehicle operation, which can damage the limiting hole 207. In other words, the display assembly 3 can be stably and effectively connected to the side cover 2.

[0124] As described above, the reinforcing rib at the limiting hole 207 extends at least partially along the extension direction of the inner wall of the limiting hole 207. With reference to FIG. 10, which is a schematic structural view of the side cover 2, and FIG. 11, which is a partial enlarged view of FIG. 10, the reinforcing rib in the figures includes longitudinal ribs 209 and transverse ribs 208 arranged in a cross manner. The longitudinal ribs 209 and the transverse ribs 208 are both in a thin plate structure. The longitudinal ribs 209 and the transverse ribs 208 together form a grid-like reinforcing rib, so that the strength of the side wall of the limiting hole 207 is increased, and the reliability of the connection between the display screen assembly 3 and the side cover 2 is ensured.

[0125] 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 rib, so as to achieve the preliminary fixation of the display screen assembly 3.

[0126] 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 and the recess 39 are matched to enhance the connection strength of the two. Specifically, in some optional embodiments, with reference to FIG. 8 and FIG. 9, the assembly surface 206 is provided with an upward protrusion 210, and the first surface 37 is provided with a recess 39 matched with the protrusion 210.

[0127] In order to fix the display screen assembly 3 to the side cover 2, the two are positioned by locking members. In some optional embodiments, referring to FIG. 4, the protruding portion 210 and the recessed portion 39 are jointly provided with a locking bolt 310 in the up-down direction. It should be particularly pointed out that the locking bolt 310 herein can be any bolt capable of achieving locking, and does not refer to a specific bolt model. Since the protruding portion 210 and the recessed portion 39 are local structures protruding from the plane, the side wall of the protruding portion 210 at the protruding position is perpendicular to the corresponding surface, so that the structural strength of the protruding portion 210 and the recessed portion 39 is greater than that of other positions of the corresponding surface, that is, a reinforcing rib technical effect is generated at the connection between the protruding portion 210, the recessed portion 39 and the corresponding surface, so that the first surface 37 or the assembly surface 206 can bear a relatively large fastening force of the locking bolt 310 without being damaged. Referring to FIGS. 4 and 8, the protruding portion 210 and the recessed portion 39 are jointly provided with two locking bolts 310. Since the protruding portion 210 and the recessed portion 39 can bear a relatively large force, the display screen assembly 3 and the side cover 2 do not need to be relatively uniformly provided with a larger number of bolts, thereby reducing the assembly difficulty. It should be additionally pointed out that the protruding portion 210 and the recessed portion 39 can bear a larger fastening force due to the enhanced strength of the corresponding position, so that the number of fastening bolts can be reduced. However, the fact that the number of locking bolts 310 is obviously increased due to other assembly requirements should not be understood as a breakthrough of the protection scope of the embodiments.

[0128] In some optional embodiments, the assembly surface 206 is provided with a protruding portion 210 protruding upward, and correspondingly, the first surface 37 is provided with a recessed portion 39 matched with the protruding portion 210. Referring to FIG. 11, in order to further increase the strength of the protruding portion 210, a reinforcing rib, marked as protruding rib 211, is arranged on the lower wall of the protruding portion 210. Correspondingly, in order to increase the strength of the recessed portion 39, referring to FIG. 13, which shows a structural schematic view of the second housing 322, a reinforcing rib, marked as recessed rib 311, is arranged on the upper wall of the recessed portion 39.

[0129] In some optional embodiments, referring to FIG. 12, the display assembly 3 comprises a display unit 31 and a display housing 32 covering at least part of the display unit 31, the display housing 32 comprises a first housing 321 and a second housing 322, the first housing 321 is above the second housing 322. Referring to FIG. 4, the locking bolt 310 penetrates the first housing 321, the second housing 322, the side cover 2 from top to bottom and is connected to the frame 1, the hole through which the first housing 321 is penetrated by the locking bolt 310 is configured as a stepped hole, the stepped hole extends downward to form a support tube 312 abutting against the side cover 2. Referring to FIG. 14, which shows a structural schematic diagram 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 assembly 3 to the side cover 2.

[0130] Referring to FIG. 15, FIG. 16 and FIG. 17, FIG. 15 is a side view of the first housing 321 and the display unit 31, FIG. 16 is a cutaway schematic diagram of the view shown in FIG. 15, and FIG. 17 is a partial enlarged view of FIG. 16, the support tube 312 penetrates the second housing 322 downward and directly abuts against the side cover 2, which can avoid the deformation of the first housing 321 caused by excessive rotation of the locking bolt 310 during assembly, thereby reducing the strength of the first housing 321. In addition, the support tube 312 is formed by extending the stepped hole downward, and the water above the first housing 321 can flow downward along the stepped hole, and the configuration of the support tube 312 penetrating the second housing 322 makes it impossible for the water above to flow into the display housing 32 through the stepped hole, thereby reducing the possibility of water entering the display housing 32.

[0131] In some optional embodiments, in order to further increase the strength of the first housing 321 at the fastening bolt, referring to FIG. 14 and FIG. 17, the lower wall of the first housing 321 is configured with a reinforcing rib connected with the support tube 312, the reinforcing rib at the support tube 312 comprises an annular rib 313 and a radial rib 314, the support tube 312 is located in the annular space of the annular rib 313, and the radial rib 314 is connected with the support tube 312 and the annular rib 313 in a radial manner. When the stepped hole is deformed downward under the extrusion of the fastening bolt, the support tube 312 tends to deform, but the radial rib 314 and the annular rib 313 generate a pulling 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, the strength of the first housing 321 at the fastening bolt.

[0132] As described above, the support tube 312 abuts against the upper wall of the side cover 2, that is, the support tube 312 abuts against the upper wall of the protrusion 210. In some optional embodiments, referring to FIG. 17, the upper wall of the second shell 322 is provided with a convex ring 315 abutting against the annular rib 313, that is, the convex ring 315 of the second shell 322 abuts against the annular rib 313 of the first shell 321, when the locking bolt 310 acts on the support tube 312 to generate stress on the annular rib 313, the abutting force of the convex ring 315 and the annular rib 313 can reduce the deformation amount of the annular rib 313, that is, the strength of the first shell 321 at the fastening bolt is improved again.

[0133] In some optional 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 shell 321 can flow downward along the stepped hole, and the upper wall of the convex ring 315 is higher than the lower end of the support tube 312, that is, there is a height difference between the two. Only when there is water accumulation in the protrusion 210 and the height of the water accumulation is higher than the convex ring 315, rainwater can enter the display shell 32 through the convex ring 315. However, the gap between the support tube 312 and the fastening bolt is obviously smaller, and a large amount of water will not flow for a short time, that is, rainwater will not enter the display shell 32 through the convex ring 315, thereby reducing the possibility of water entering the display shell 32.

[0134] In some optional embodiments, referring to FIG. 7, the display screen assembly 3 is further provided with a switch assembly, that is, the connecting part of the display screen assembly 3 is provided with a switch assembly, and the switch assembly includes a whole vehicle switch 34 and / or an operation part control switch 35. The whole vehicle switch 34 is used to control whether the multifunctional operation vehicle is in a powered state, and when the user starts to drive the vehicle, the whole vehicle should be in a powered state by operating the whole vehicle switch 34, and then the vehicle is controlled to work by the active steering assembly and other parts. The operation part control switch 35 is used to control the start or stop of the outdoor operation part when the vehicle is in a powered state, and is used to control the opening and closing of the outdoor operation part by the operation part control switch 35 after the vehicle drives to the operation, so as to realize the operation on the to-be-operated area.

[0135] Referring to FIG. 6, the assembly surface 206 of the side cover 2 is provided with a wire hole 212, the display screen assembly is provided with a switch assembly for controlling the state of the vehicle, and the switch assembly is connected with a wire extending downward and penetrating through the wire hole 212. The wire penetrates downward to the side cover 2 through the wire hole 212 and is connected to the controller of the vehicle along the vehicle frame 1.

[0136] The switch assembly is located on the side of the steering hole 33 close to the inside of the vehicle. As mentioned above, the active steering assembly is arranged in the steering hole 33, and as a component with a significantly higher operation frequency than the switch assembly, the component held by the user is significantly higher than the side cover 2, so as to avoid the switch assembly being accidentally touched when the active steering assembly is operated. At the same time, 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 close to the inside of the vehicle in the left-right direction of the vehicle.

[0137] That is, for the embodiment in which the display screen assembly 3 is arranged 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 arranged on the left side of the vehicle, the switch assembly is located on the right side of the steering hole 33.

[0138] In some optional embodiments, referring to FIG. 1 and FIG. 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 can also deflect outwardly. In this embodiment, the switch assembly is arranged on the left side of the steering hole 33, so as to avoid interference between the joystick 4 and the switch assembly when the joystick 4 deflects outwardly.

[0139] In some optional embodiments, in order to facilitate the user to interact with the control system of the vehicle through the display screen assembly 3, the display unit 31 of the display screen assembly 3 is arranged with buttons for the user to operate, so that the user can adjust the content displayed by the display unit 31 through the buttons, or send instructions to the vehicle through the buttons, etc.

[0140] In some optional embodiments, water is not allowed to enter the inside of the display unit 31, and physical buttons are prone to have gaps in the display unit 31. Therefore, a waterproof component is arranged at the button to prevent water from entering the display unit 31 through the gap of the physical button. Referring to FIG. 19, the button of the display unit 31 is marked as “key body 3111” in the figure.

[0141] In some optional embodiments, referring to FIG. 18, a structure diagram of a first housing 321 is shown in the figure, the first housing 321 is arranged with a key hole 3211 through which the button passes, and the key hole 3211 is arranged with a flexible sealing member 3112. The first housing 321 and the display unit 31 jointly extrude the sealing member 3112 and form a sealed space wrapping the button, so that external water cannot enter the display unit 31 through the gap. That is, the display screen assembly can maintain normal working state in a rainy environment, and the vehicle can be arranged with the display screen assembly in this embodiment and work normally in a rainy environment.

[0142] In order to reduce weight and save material cost, the first shell 321 is generally made of plastic material 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 the buttons, two or more buttons are generally configured, and a key hole 3211 and a sealing member 3112 are configured at each button. For a display unit 31 with a smaller size, the sealing effect of the sealing member 3112 can still be effectively maintained by the bolts at the edge. However, for a display unit 31 with a larger size, the first shell 321 made of plastic material is difficult to maintain a larger rigidity at the center position, thereby causing the pressing force of the sealing member 3112 to be slightly smaller and unable to effectively satisfy the sealing effect.

[0143] Therefore, in some optional embodiments, referring to FIG. 18, the display unit 31 is spaced apart from at least two buttons, the first shell 321 is provided with at least two key holes 3211, and at least two of the key holes 3211 of the first shell 321 are provided with bolts. The bolts here mainly play a sealing effect. In order to distinguish from the bolts at other positions, the bolts here are collectively referred to as “sealing bolts 3113”. This is only named by the function of the bolts and does not necessarily refer to the specific type of bolts. That is, in this embodiment, the bolts here can be selected from any type of bolts that can effectively fasten the first shell 321 and the display unit 31 and press the sealing member 3112.

[0144] The sealing bolts 3113 connect the first shell 321 and the display unit 31 and press the sealing member 3112. The sealing bolts 3113 and the bolts cooperating with the edge of the display unit 31 and the first shell 321 achieve the sealing effect of the sealing member 3112. Specifically, the presence of the sealing bolts 3113 improves the rigidity of the first shell 321 at the sealing member 3112, so that the first shell 321 can tightly abut the display shell 32, and the abutment of the sealing member 3112 and the display shell 32 can achieve effective sealing, that is, an effective sealing space can be generated to achieve the technical effect of waterproofing.

[0145] In some optional embodiments, referring to FIG. 18, the first housing 321 is linearly arranged with five key holes 3211, and the first housing 321 is arranged with four sealing holes 3212, the sealing bolt 3113 penetrates the sealing hole 3212 and is screwed to the display unit 31, and two sealing holes 3212 are respectively located between two key holes 3211. Specifically, the five key holes 3211 and the four sealing holes 3212 are linearly arranged in the following order: the first sealing hole 3212, the first key hole 3211, the second key hole 3211, the second sealing hole 3212, the third key hole 3211, the third sealing hole 3212, the fourth key hole 3211, the fifth key hole 3211, and the fourth sealing hole 3212. In other embodiments, the number of key holes 3211 can be freely adjusted according to the number of buttons required, but in order for the sealing member 3112 to effectively seal the button, at least one sealing hole 3212 is located between two key holes 3211, which can meet the requirement that the sealing member 3112 at the key hole 3211 can effectively seal the button after the first housing 321 with a larger area is matched with the display unit 31.

[0146] In another optional embodiment, the first housing 321 is not arranged with the above-mentioned sealing hole 3212, but a through hole is arranged in the display unit 31, and an internal thread is arranged in the first housing 321, the sealing bolt 3113 penetrates the through hole of the display unit 31 and is screwed to the internal thread of the first housing 321, so as to extrude the sealing member 3112 to achieve the sealing effect. The sealing bolt 3113 of the present embodiment is not directly exposed to the outside, which not only makes the outer shell of the first housing 321 look more simple, but also avoids the phenomenon of rust caused by the contact of the sealing bolt 3113 with rainwater.

[0147] In some optional embodiments, referring to FIG. 7 and FIG. 20, the display unit 31 further includes an inclined screen, and the display housing 32 is arranged with a screen hole for exposing the screen outward. For some embodiments, the lower edge 3213 of the display unit 31 abutting with the screen hole is difficult to keep completely sealed, that is, the connection part may have a water seepage phenomenon. Therefore, the display unit 31 is provided with a water guide groove 3114 located on the lower side of the outer wall of the screen. When rainwater flows into the display housing 32 through the gap between the screen hole and the display unit 31, it flows to the bottom of the second housing 322 through the water guide groove 3114. Referring to FIG. 13, the bottom of the second housing 322 is arranged with a water drain hole 3221, so that the water in the second housing 322 can flow out. As shown in the figure, two water drain holes 3221 are arranged, which can keep smooth drainage when one of the water drain holes 3221 is blocked.

[0148] In some optional embodiments, the display unit 31 is configured with a touch screen that can be controlled by the user's touch, so the screen hole should be a through hole, and no transparent glass layer that affects touch control is configured.

[0149] In some optional embodiments, referring to FIG. 14, the display unit 31 is configured with a signal line hole 36 on the side away from the first shell 321, a wire (not shown) connecting the screen and the riding mower is threaded through the signal line hole 36, and the signal line hole 36 is coated with sealant (not shown).

[0150] In some optional embodiments, the multifunctional work vehicle further comprises a passive wheel 8 and a seat 5; the passive wheel 8 is arranged at the front of the frame 1 on the side of the display screen assembly 3; the seat 5 is used to carry the user; the passive wheel 8 is at least partially visible to the driver sitting on the seat 5 and is not blocked by the display screen assembly 3. Referring to FIG. 1 and FIG. 2, the multifunctional work vehicle shown in the figures comprises two universal wheels, one of which is located at the front on the side of the display screen assembly 3, which is the aforementioned passive wheel 8.

[0151] The passive wheel 8 is visible to the user and is not blocked by the display screen, so that the user can determine the edge of the work area through the passive wheel 8 when driving the vehicle and working, so as to avoid missing and other problems during work. Specifically, in some optional embodiments, the aforementioned outdoor work component is a cutting deck 6 with a cutting knife, and the multifunctional work vehicle is a mower at this time. When the user drives the mower to mow the lawn, the user needs to drive in a zigzag manner, and generally controls a small amount of overlap between the current mowing area and the mowed area during straight driving to avoid missing the grass, so the user needs to know at all times whether the current mowing range meets the expectations. In this embodiment, part of the passive wheel 8 is not blocked and is in a visible state, and the user's line of sight when looking at the passive wheel 8 is similar to the line of sight when looking at the display screen assembly 3, so the user can quickly switch between looking at the passive wheel 8 and looking at the display screen assembly 3; and when looking at the outline of the passive wheel 8, the outline of the passive wheel 8 can be compared with the mowed area of the ground to determine the relative position relationship between the current mowing area and the mowed area according to the user's experience. If there is no overlap or the overlap is too large between the current mowing area and the mowed area, the vehicle should be adjusted in direction through the active steering assembly until a small amount of overlap exists between the current mowing area and the mowed area.

[0152] 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 determine whether the vehicle position and angle are appropriate through the position 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 obviously look at the content changes of the display screen assembly 3, and if the display screen assembly 3 has information such as alarms, the user will also be more timely informed.

[0153] In some optional embodiments, to enable the user to clearly see the information of the display unit 31, the orientation of the display unit 31 is relatively close to the head of the user, for the convenience of description and understanding, the following definitions are made: a first plane is parallel to the ground; the front-rear direction of the vehicle is a first direction; a second plane is perpendicular to the first plane and passes through the first direction.

[0154] For the safety and comfort of the passengers, the seat 5 includes a seat cushion and a backrest, and the line connecting the center of the top of the seat 5 and the center of the display unit 31 is a first straight line, the projection of the first straight line on the first plane has an angle with the first direction less than or equal to 40°, as shown in FIG. 21, the straight line a is the projection of the first straight line on the first plane, and the straight line b is parallel to the first direction, that is, the angle a between the straight line a and the straight line b is less than or equal to 40°; the projection of the first straight line on the second plane has an angle with the first direction less than or equal to 50°, as shown in FIG. 22, the straight line c is the projection of the first straight line on the second plane, and the straight line d is parallel to the first direction, that is, the angle β between the straight line c and the straight line d is less than or equal to 50°.

[0155] The part of the vehicle closest to the head of the user is the backrest of the seat 5, so 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 line of sight of the user, and the line of sight of the user is more often the first direction when the user is driving the vehicle normally, so the above-mentioned angle between the projection of the first straight line on the first plane and the first direction and the angle between the projection of the first straight line on 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-mentioned angle less than or equal to 40° and less than or equal to 50° indicates that the user needs to tilt the line of sight to see the display screen clearly.

[0156] In some optional embodiments, the angle between the projection of the first straight line on 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 optional embodiments, the angle between the projection of the first straight line on the second plane and the first direction is greater than 30° and less than or equal to 50°. That is, the display screen is obviously located on the oblique lower side of the seat 5, avoiding the display unit 31 from blocking the view of the front of the vehicle and affecting outdoor work.

[0157] In some optional embodiments, a straight line passing through the center of the display unit 31 and perpendicular to the plane of the display unit 31 is defined as a second straight line.

[0158] In some optional embodiments, the second straight line in the first plane has an angle with the first direction greater than or equal to 5° and less than or equal to 25°. Referring to FIG. 23, a top view of the side cover 2 is shown, where a straight line e is the projection of the second straight line in the first plane, and a straight line f is parallel to the first straight line. In the drawing, the angle δ between the straight line e and the straight line f is in the range of 25°≥δ≥5°, that is, the display unit 31 is inclined to the side of the seat 5 to a certain extent in the top view.

[0159] The projection of the second straight line in the second plane has an angle with the first direction greater than or equal to 40° and less than or equal to 65°. Referring to FIG. 24, a side view of the side cover 2 is shown, where a straight line g is the projection of the second straight line in the second plane, and a straight line h is parallel to the first straight line. In the drawing, the angle ε between the straight line g and the straight line h is in the range of 65°≥ε≥40°, that is, the display unit 31 is inclined upward to a certain extent in the side view.

[0160] The two angles δ and ε represent the orientation of the display unit 31, specifically the orientation of the screen part of the display unit 31, which mainly affects whether it is directed to the user's face or the extent of deviation from the user's face. In some optional embodiments, the projection of the second straight line in the first plane has an angle with the first direction greater than or equal to 10° and less than or equal to 20°, that is, 20°≥δ≥10°; in addition, in some optional embodiments, the projection of the second straight line in the second plane has an angle with the first direction greater than or equal to 50° and less than or equal to 60°, that is, 60°≥ε≥50°. Within this angle range, the user sitting on the seat 5 can clearly see the information displayed by the display unit 31.

[0161] In some optional embodiments, the position of the second straight line is higher than the position of the first straight line on the side of the display unit 31 close to the seat 5, that is, the display unit 31 is inclined to the directly above or obliquely above of the seat 5; since the first straight line and the second straight line have an intersection point on the display unit 31, the first straight line and the second straight line are coplanar and have an angle, 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 is higher than the top of the seat 5 when sitting on the seat 5, the display unit 31 inclined to the directly above or obliquely above of the seat 5 is closer to the user's eyes, making it more convenient for the user to clearly see the information of the display unit 31.

[0162] 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°, and the user's eyes are within this angle range when sitting on the seat 5, so that the user can more clearly see the information of the display unit 31.

[0163] In some optional embodiments, the maximum visual angle of the display unit 31 is 40°-70°. That is, the angle between the visual line and the normal line of the plane of the display unit 31 is less than the maximum visual angle range, and the content displayed by the display unit 31 can be effectively seen.

[0164] In some optional 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 450 mm-750 mm, that is, the value of X in FIG. 21 is 450 mm-750 mm. 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 550 mm-650 mm. This range conforms to the arm length range of normal adults, and the user can touch the display unit 31 by stretching the arm or slightly leaning forward, that is, the above distance range is obviously more in line with ergonomics.

[0165] In some optional embodiments, the present specification also discloses a multifunctional work vehicle, which comprises a frame 1, a user platform, an outdoor work component, a drive wheel 7, a side cover 2, a display screen assembly 3, and an active steering assembly. The frame 1 extends in a first direction, that is, the front-rear direction of the vehicle. The user platform is arranged on the frame 1 and is used to carry the user. The outdoor work component is arranged on the frame 1 and is used to perform outdoor work. The drive wheel 7 is arranged on the left and right sides of the frame 1 and is used to drive the vehicle to travel. The side cover 2 is arranged on the frame 1 and is located on the left side and / or the right side of the vehicle. The display screen assembly 3 is arranged 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 operatively arranged on the frame 1 and is used to control the speed change of the drive wheel 7 on at least one side of the vehicle.

[0166] In some optional embodiments, the active steering assembly, the display screen assembly 3, the side cover 2, and the frame 1 at least partially coincide in the orthographic projection on the ground. That is, the active steering assembly, the display screen assembly 3, and the side cover 2 have a small horizontal distance. When the user looks at the active steering assembly, the eyes can see the content of the display screen, that is, the user can obtain the state information of the vehicle in time through the display unit 31 when operating, thereby improving the safety of the vehicle. In the prior art, the display screen is far away from the operating component held by the user, which causes the user to frequently turn the head to see the display screen, and thus serious safety hazards may occur.

[0167] In some optional embodiments, the display screen assembly 3 is further provided with a switch assembly, i.e., the connection part of the display screen assembly 3 is provided with a switch assembly, and the switch assembly includes a whole vehicle switch 34 and / or an operation part control switch 35. The whole vehicle switch 34 is used to control whether the multifunctional operation vehicle is in a powered state, and when the user starts to drive the vehicle, the whole vehicle switch 34 should be controlled to make the whole vehicle in the powered state, and then the vehicle is controlled to work through the active steering assembly and other parts. The operation part control switch 35 is used to control the start or stop of the outdoor operation part when the vehicle is in the powered state, and is used to control the start or stop of the outdoor operation part through the operation part control switch 35 after the vehicle is driven to the operation, so as to realize the operation on the region to be operated.

[0168] In some optional embodiments, the display screen assembly 3 includes a display unit 31 and a display housing 32 wrapping at least part of the display unit 31, and the active steering assembly and / or the whole vehicle switch 34 and / or the operation part control switch 35 are located closer to the rear side of the vehicle relative to the display unit 31. That is, the active steering assembly and / or the whole vehicle switch 34 and / or the operation part control switch 35 are located closer to the user side relative to the display unit 31, so as to facilitate the user to manually control the active steering assembly and / or the whole vehicle switch 34 and / or the operation part control switch 35. Because the distance between the active steering assembly and / or the whole vehicle switch 34 and / or the operation part control switch 35 and the display unit 31 is short, when the user looks at the active steering assembly and / or the whole vehicle switch 34 and / or the operation part control switch 35 and controls them, the remaining light can observe the content displayed by the display unit 31, that is, the user can timely obtain the state information of the vehicle through the display unit 31 when controlling, so as to improve the safety of the vehicle.

[0169] In some optional embodiments, as shown in FIG. 25, the display unit 31 comprises at least one button for user operation, and the distance between at least one of the buttons and the whole vehicle switch 34 or the work component control switch 35 in the first direction is 20-100 mm, i.e., the range of Y in the figure is 20-100 mm. As described above, the display unit 31 is closer to the whole vehicle switch 34 or the work component control switch 35, which is convenient for the user to obtain the vehicle state information. However, when the user operates the whole vehicle switch 34 or the work component control switch 35, the display unit 31 should not interfere with the user's hand, i.e., the display unit 31 should not block the user's hand from operating the whole vehicle switch 34 or the work component control switch 35. The distance in the first direction described above is less than or equal to 100 mm, which meets the space for the user's hand movement. In some embodiments, the buttons of the display unit 31 are offset from the whole vehicle switch 34 or the work component control switch 35 in the left-right direction of the vehicle, so the distance between the buttons and the whole vehicle switch 34 or the work component control switch 35 in the first direction is appropriately shortened, and no interference occurs. However, for the convenience of arrangement, the buttons still need to be arranged to have a distance of 20 mm from the whole vehicle switch 34 or the work component control switch 35 in the first direction. Therefore, the distance between at least one of the buttons and the whole vehicle switch 34 or the work component control switch 35 in the first direction is 20-100 mm.

[0170] In some optional embodiments, the seat 5 on which the user sits comprises 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 420-720 mm. 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 550-650 mm. This range meets the length range of the arms of normal adults, and the user can operate the buttons by stretching the arms or slightly leaning forward, i.e., the distance range described above is obviously more in line with ergonomics.

[0171] In some optional embodiments, as shown in FIGS. 1 and 2, the multifunctional work vehicle comprises only one display screen assembly 3, and one active steering assembly penetrates the display screen assembly 3. The user only needs to look to one side to obtain the information displayed on the display screen assembly 3.

[0172] As mentioned above, the multi-functional work vehicle comprises two active steering assemblies, and the active steering assemblies control the speed change of the corresponding drive wheels 7 when moving forward and backward. In some more specific embodiments, the display assembly 3 is provided with a steering hole 33 for the corresponding active steering assembly to pass through. The display assembly 3 comprises a display part and a connecting part, and the steering hole 33 is arranged on the connecting part. The display assembly 3 is close to the corresponding active steering assembly, so that the user can more conveniently see the information displayed by the display assembly 3 when looking at the active steering assembly.

[0173] In some more specific embodiments, the forward movement of the active steering assembly controls the forward rotation of the corresponding drive wheel 7, the backward movement of the active steering assembly controls the backward rotation of the corresponding drive wheel 7, and 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 not equal, the vehicle will turn, so the two active steering assemblies control the forward and backward movement and turning of the vehicle through their movement.

[0174] In some more specific embodiments, the active steering assembly can also move in the left-right direction. Specifically, referring to FIG. 5 and FIG. 7, after the right active steering assembly moves to the right, it is limited by the steering hole 33 and cannot move in the forward-backward direction any more, and after the left active steering assembly moves to the left, it cannot move in the forward-backward direction any more; and the right movement of the right active steering assembly or the left movement of the left active steering assembly will make the vehicle enter the parking state, and the vehicle in the parking state needs to be unlocked to control the rotation of the drive wheel 7.

[0175] In some optional embodiments, referring to FIG. 1 and FIG. 2, the display assembly 3 is arranged on the right side of the vehicle, and the corresponding steering hole 33 is arranged as a T-shaped hole (T is placed horizontally) that can move to the right when the active steering assembly moves in the forward-backward direction to the middle position, 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.

[0176] In some more specific embodiments, for the user carried on the user platform, when the active steering assembly moves to the right to make the vehicle enter the parking state, the display unit 31 is not blocked by the active steering assembly and is visible. The wheels in the parking state do not rotate, that is, the wheels are in a safe state, and the display unit 31 in this state should be freely controlled by the user, so the active steering assembly should not block the display unit 31.

[0177] In some optional embodiments, when the active steering assembly moves to the left and the display unit 31 is partially blocked by the active steering assembly and is not fully visible when moving forward and backward along the steering hole 33. Because when the active steering assembly is in the state of moving forward and backward along the steering hole 33, the vehicle is in a non-parking state, and the vehicle may be moving or has a certain risk at this time, the display unit 31 at this time should only be a display part. The user should not take his hands off the active steering assembly and touch the display unit 31, so the active steering assembly is set to block the display unit 31, even if the user's hands are off the active steering assembly, it is also blocked by the active steering assembly and it is not easy to touch the display unit 31. That is, the user is forced to operate the active steering assembly to the right to make the vehicle enter the parking state, and the vehicle is relatively safe to make the user easily touch the display unit 31.

[0178] In some more specific embodiments, the display screen assembly 3 does not obviously protrude upward from the highest point of the side cover 2. That is, the height of the display screen assembly 3 is roughly equivalent to or lower than the side cover 2. As mentioned above, the display unit 31 of the display screen assembly 3 protrudes forward from the side cover 2, and the purpose of this embodiment of controlling the display screen assembly 3 not to obviously protrude upward is to reduce the probability of collision with external objects. When external objects may impact the vehicle of this embodiment in a transverse direction, the side cover 2 bears the impact force more likely to avoid damage to the display screen assembly 3, and avoid greater economic damage caused by damage to the relatively fragile display screen assembly 3.

[0179] In some optional embodiments, referring to FIG. 1 and FIG. 6, the side cover 2 is provided with a height adjustment groove 205, and a height adjustment rod 10 operatively connected to the frame 1 is rotatably arranged in the height adjustment groove 205. The height adjustment rod 10 drives the height change of the outdoor working component when rotating, so as to adapt to the actual needs of different users for outdoor work. The height adjustment rod 10 is located closer to the rear side of the vehicle relative to the display screen assembly 3, because the weight of the outdoor working component may be large, and the height adjustment rod 10 is closer to the user, which is convenient for the user to exert force to adjust the height of the outdoor working component.

[0180] In some optional embodiments, referring to FIG. 4, the frame 1 includes a main frame body and a bridge member 101 fixed to the main frame body. The bridge member 101 is a metal connecting member for assisting in mounting the side cover 2, the display unit housing 32, etc., and can be regarded as a part of the frame 1. Further, in this embodiment, the display unit housing 32, the side cover 2, and the bridge member 101 are all provided with steering holes 33 for the active steering assembly to pass through.

[0181] In some optional embodiments, the multifunctional work vehicle further comprises a vehicle controller (not shown) for controlling the working state of the vehicle, the vehicle switch 34 and / or the work component control switch 35 are connected to the vehicle controller through wires, and the side cover 2 is provided with wire holes for the wires of the vehicle switch 34 and / or the work component control switch 35 or the wires to pass through, as shown in FIG. 6.

[0191] As described above, in at least one embodiment of the present specification, the sealing of the key hole is achieved by the flexible sealing member, and specifically, the bolts that press the sealing members are arranged between at least two key holes, so that even for a display unit with a slightly larger size, the display housing can be tightly abutted to the display unit to better press the sealing members, thereby achieving effective sealing and ensuring that the display screen assembly can meet the working requirements in rainy weather. Thus, the technical problem that the configuration of the vehicle is relatively limited due to the need to consider waterproofing requirements in the field of lawn mowers and other garden work vehicles or outdoor work vehicles in the prior art is solved, especially when some snow weather needs to be worked on, in order to make the vehicle more flexible, the outdoor work vehicle often does not configure an effective waterproof cab, resulting in the configuration of the vehicle being relatively limited due to the need to consider waterproofing requirements.

[0192] In another optional embodiment, the utility vehicle further comprises a user platform for carrying a user, and a normal line of a plane on which the display unit 31 displays a pattern is directed to a position directly above the user platform, and the user is carried on the user platform, i.e. the head of the user is approximately located at the position directly above the user platform, and thus a vertical line of a surface on which the display unit 31 displays a pattern, i.e. a screen of the display unit 31, is directed to the position directly above the user platform, so as to facilitate the user to clearly see the information displayed by the display unit 31.

[0193] In one optional embodiment, the display housing 32 of the utility vehicle comprises a connecting portion connected to the side cover 2 in a substantially horizontal manner and a display portion extending in a manner different from that of the connecting portion, and the display assembly 3 comprises a display unit 31 arranged on the display portion and used for displaying pattern or character information. That is, the display assembly 3 comprises two portions extending in different directions, the connecting portion is in contact with the side cover 2 and remains in a substantially horizontal state, and the display portion is inclined to face the face of the user, so as to avoid the user from needing to significantly turn the head downward to clearly see the information of the display unit 31.

[0194] It should be particularly noted that the "substantially horizontal" of the connecting portion should be understood as an angle with the horizontal direction being small, such as an angle within ±15° with the horizontal direction, which should all be understood as the aforementioned substantially horizontal. Because within the angle range, the naked eye cannot obviously observe that it is not horizontal.

[0195] In one optional embodiment, the utility vehicle further comprises a user platform for carrying a user, and a normal line of a plane on which the display unit 31 displays a pattern is directed to a position directly above the user platform, and the user is carried on the user platform, i.e. the head of the user is approximately located at the position directly above the user platform, and thus a vertical line of a surface on which the display unit 31 displays a pattern, i.e. a screen of the display unit 31, is directed to the position directly above the user platform, so as to facilitate the user to clearly see the information displayed by the display unit 31.

[0196] In another optional embodiment, the utility vehicle further comprises a user platform for carrying a user, and a normal line of a plane on which the display unit 31 displays a pattern is directed to a position directly above the user platform, and the user is carried on the user platform, i.e. the head of the user is approximately located at the position directly above the user platform, and thus a vertical line of a surface on which the display unit 31 displays a pattern, i.e. a screen of the display unit 31, is directed to the position directly above the user platform, so as to facilitate the user to clearly see the information displayed by the display unit 31.

The purpose of the first surface 37 and the assembly surface 206 being approximately horizontal is that, during assembly, when the display assembly 3 is placed on the assembly surface 206, the display assembly 3 will not slide and deviate due to gravity, thereby facilitating assembly.

[0198] In the embodiment, the display portion extends in a direction different from the connecting portion, because the display portion is mainly used to display pattern or character information to the user through the display unit 31. As described above, the connecting portion extends in a horizontal direction, so the plane of the connecting portion faces directly upward. If the user looks at the connecting portion, he or she needs to lower his or her head to make his or her line of sight vertical downward, so as to clearly see the characters on the surface of the connecting portion. The display portion extends in a direction different from the connecting portion, that is, the display unit 31 is in an inclined state relative to the horizontal plane, so that the user can see the content displayed by the display unit 31 without significantly lowering his or her head.

[0199] In some optional embodiments, the multifunctional work vehicle includes a user platform used to carry the user, and the normal line of the plane on which the display unit 31 displays the pattern points directly upward of 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, the normal line of the plane on which the display unit 31 displays the pattern points directly upward of the user platform, that is, approximately points to the user's head, thereby facilitating the user to watch the pattern or character information displayed by the display unit 31. In some optional embodiments, the part of the display unit 31 used to display the pattern is a screen, and the above-mentioned plane on which the pattern is displayed is the surface of the screen.

[0200] In some optional embodiments, the connecting portion is arranged with a switch assembly, and the switch assembly includes a whole vehicle switch 34 and / or a work component control switch 35. The whole vehicle switch 34 is used to control whether the multifunctional work vehicle is in a powered-on state. The work component control switch 35 is used to control the start or stop of the outdoor work component when the vehicle is in the powered-on state. That is, the switch assembly and the display unit 31 are both located at the display assembly 3, so that the user can conveniently control the switch assembly while looking at the display unit 31. In other words, when the user controls the switch assembly to control the state of the vehicle, he or she can conveniently watch the information displayed by the display unit 31 to confirm whether the state of the vehicle meets his or her expectation.

[0201] In some optional embodiments, the multi-functional working vehicle further comprises driving wheels 7, and a main steering assembly; the driving wheels 7 are arranged on the left and right sides of the vehicle frame 1 and are used to drive the vehicle to move; the main steering assembly is operatively connected to the left and / or right side of the vehicle frame 1 and is used to make the driving wheels 7 on the left and right sides have different rotating speeds so as to make the vehicle turn.

[0202] In some optional embodiments, at least one of the main steering assemblies penetrates the connecting part, and the display unit 31 is located in front of the main steering assembly, so that the display unit 31 does not affect the operation of the main steering assembly.

[0203] In some optional embodiments, the display housing 32 is provided with a steering hole 33 which is penetrated by the main steering assembly; when the main steering assembly is operated by the user to move forward or backward in the steering hole 33, the main steering assembly controls the change of the rotating speed of at least one of the driving wheels 7; the steering hole 33 is configured as a T-shaped hole which can move left or right when the main steering assembly moves to the middle position in the front-back direction, that is, the main steering assembly does not interfere with the side wall of the steering hole 33 when moving forward or backward or moving rightward.

[0204] In some more specific embodiments, for the user on the user platform, when the main steering assembly moves rightward to make the vehicle enter a parking state, the display unit 31 is not blocked by the main steering assembly and is visible. The wheels do not rotate in the parking state, that is, the wheels are in a safe state; the display unit 31 in this state should be freely operated by the user, so the main steering assembly should not block the display unit 31.

[0205] In some optional embodiments, the display unit 31 comprises a touch screen which can be touched by the user; the user can complete the signal input to the display unit 31 by touching, so as to control the state of the vehicle.

[0206] In some optional embodiments, when the active steering assembly moves left and the display unit 31 is partially blocked by the active steering assembly and is not fully visible when the display unit 31 moves back and forth along the steering hole 33. Because when the active steering assembly is in the non-parking state and the vehicle can move or is moving, it is dangerous. At this time, the display unit 31 should only be a display part. The user should not take his hands off the active steering assembly and touch the display unit 31, so the active steering assembly is set to block the display unit 31, and even if the user's hands are off the active steering assembly, it is difficult to touch the display unit 31. That is, the user is forced to move the active steering assembly to the right to make the vehicle enter the parking state, and the vehicle is relatively safe to make the user easily touch the display unit 31.

[0207] In another optional embodiment, a riding mower is also disclosed, which comprises a vehicle frame 1, an outdoor working component, a side cover 2, and a display screen assembly 3.

The display screen assembly 3 comprises a display unit 31 configured to the display portion and used to display pattern or character information.

[0209] As mentioned above, in at least one of the embodiments of the present disclosure, the part of the display screen assembly used for displaying pattern or character information does not extend along the horizontal direction, but has a clear inclination angle with the horizontal direction, so that the user can see the content displayed on the display screen without significantly lowering his head, which is convenient for the user to watch and improves the safety of the vehicle driving. The safety risk problem caused by the display screen being configured as nearly horizontal and the user needing to significantly lower his head to see it in the prior art is solved.

[0210] In another optional embodiment, a multifunctional work vehicle is also disclosed, which comprises a vehicle frame 1 extending along a first direction, i.e. the front-rear direction of the vehicle; an outdoor work component configured on the vehicle frame 1 and used for performing outdoor work; a side cover 2 configured on the vehicle frame 1 and located on the left side and / or right side of the vehicle; and a display screen assembly 3 configured on the side cover 2 and used for displaying pattern or character information to the user. The display screen assembly 3 comprises a screen with an area of not less than 80cm 2 . The relatively large screen size enables the display screen assembly to present more information to the user, and in addition, the large screen can display the corresponding information in a larger icon or font size, so that the user can more easily distinguish the information displayed on the screen, improving the practicability of the screen. In addition, because the screen is large and can display more information, i.e. the user can obtain more information within one interface of the screen, the user can also make the best decision about the outdoor work according to the more information obtained. For example, the user can obtain the information such as the remaining range, the remaining area to be worked, the time or the weather in the next few hours within one interface of the screen, and then make the best decision whether to continue working or not.

[0211] In one of the optional embodiments, the area S of the screen of the display screen assembly 3 is greater than or equal to 100cm 2 . In another optional embodiment, the area S of the screen of the display screen assembly 3 is greater than or equal to 120cm 2 .
