Description

[Technical Field] This application relates to the field of work vehicle technology, and in particular to an outdoor work vehicle. [Background Technology] Outdoor work vehicles, especially outdoor garden lawnmowers, often lack protective plates for their power management devices. This makes them prone to collisions with hard objects on the ground during operation. In particular, the power management devices located at the rear of the frame are easily damaged when the lawnmower is going uphill as they can easily come into contact with the ground.

[0001] Therefore, it is indeed necessary to provide an improved storage box for outdoor work vehicles to overcome the shortcomings of the prior art. [Summary of the Invention] In view of the shortcomings of the prior art, the purpose of this application is to provide an outdoor work vehicle that protects and dissipates heat from the power management device.

A protective component is disposed below the power management device. The protective cover is used to protect at least the power management device. An air inlet and an air outlet are formed between the protective component and the power management device, as well as an airflow channel located between the air inlet and the air outlet. Debris generated during the operation of outdoor work vehicles can enter the airflow channel from the air inlet and be discharged from the air outlet.

[0003] A further improvement is as follows: along the first direction, the midpoint of the line connecting the frontmost and rearmost ends of the protective component is defined as the center point. The protective component is divided into a first protective part and a second protective part by a straight line passing through the center point in the horizontal direction. The projected area of ​​the first protective part in the vertical direction is smaller than the projected area of ​​the second protective part.

[0004] A further improvement is that the protective component is provided with a through hole, which can discharge grass and guide airflow.

[0005] A further improvement is that the through hole is provided on the protective component near the rear of the frame.

[0006] A further improvement is that the frame includes a longitudinal beam arranged along a first direction and a crossbeam connected to the longitudinal beam, and the protective component is connected to the longitudinal beam and the crossbeam.

[0007] A further improvement is as follows: the frame includes a first support portion configured to support a seat, a second support portion configured to support a power supply device, and a connecting portion connecting the first support portion and the second support portion, wherein the first support portion and the second support portion have different heights, and the protective member is connected to the second support portion and the connecting portion.

[0008] A further improvement is as follows: the second load-bearing part is arranged horizontally, the connecting part is arranged at an angle, and the protective member includes a first protective part arranged horizontally and a second protective part arranged at an angle, the first protective part being connected to the second load-bearing part and the second protective part being connected to the connecting part.

[0010] A further improvement is that, along the first direction, the protective component is located between the first axis and the rearmost end of the outdoor work vehicle.

[0011] A further improvement is that the protective component has a plate-like structure and is made of metal.

[0012] This application also provides an outdoor work vehicle, including: A frame, the frame including longitudinal beams arranged along a first direction and crossbeams connected to the longitudinal beams; A walking assembly is disposed on the vehicle frame and configured to support the movement of the outdoor work vehicle; A cutting assembly, disposed on the vehicle frame and configured to cut vegetation; A power supply device, at least for supplying power to the outdoor work vehicle; A power management device is disposed below the power device, and the power management device is at least used to control the charging or discharging of the power device. A protective component is disposed below the power management device. The protective cover serves at least to protect the power management device. An air inlet and an air outlet are formed between the protective component and the power management device, as well as an airflow channel located between the air inlet and the air outlet. Debris generated during the operation of outdoor work vehicles can enter the airflow channel through the air inlet and be discharged through the air outlet.

[0018] Please see Figures 1 to 7 The image shows an outdoor work vehicle according to one embodiment of the present application. The outdoor work vehicle includes a frame 100, a power supply device 200, an operating component 300, a seat 400, a power output component 500, and a walking component 600.

[0019] The frame 100 extends in one direction, and the power supply unit 200 is located at the rear of the frame 100. The power supply unit 200 includes a battery pack, a power management device 219 for controlling the output and input of the battery pack, and a battery compartment 201 for mounting the battery pack. The battery pack is electrically connected to the battery compartment via its terminal contacts to provide power to the outdoor work vehicle. The battery pack includes a first type of battery pack and a second type of battery pack. Preferably, the battery compartment can be configured to accommodate first type and second type battery packs of different capacities or sizes to increase the compatibility of the outdoor work vehicle with different battery packs. The battery pack can also be detached to power other power tools, increasing its versatility. Compared to traditional energy sources using fossil fuels, the outdoor work vehicle of this application is more environmentally friendly and better suited to long-term development plans. Preferably, the battery pack is a lithium iron phosphate battery pack or a ternary lithium battery pack.

[0020] In one embodiment, the first type of battery pack includes a ternary lithium battery pack, and the second type of battery pack includes a lithium iron phosphate battery pack.

[0021] The operating component 300 includes a left and a right control lever located on the left and right sides of the outdoor work vehicle, respectively. Users control the outdoor work vehicle to move forward, backward, or turn by manipulating the left and right control levers. The operating component 300 can also be a steering wheel for controlling the outdoor work vehicle.

[0022] In one embodiment, the operating component 300 is provided with control buttons for adjusting the operating speed of the power output component 500 and the travel component 600, so as to facilitate the user to quickly and accurately control the operation of the outdoor work vehicle. Furthermore, the operating component 300 may also be provided with buttons for adjusting the brightness of the vehicle's headlights.

[0023] The seat 400 is mounted on the frame 100, and the left and right control levers are positioned close to the seat 400 and on the left and right sides of the seat 400, so that the user sitting on the seat 400 can operate the left and right control levers to control the operation of the outdoor work vehicle.

[0024] The power output assembly 500 serves as a tool function. In one embodiment, the outdoor work vehicle is a ride-on lawnmower, and the power output assembly 500 is specifically a cutting assembly, located below the frame 100. It outputs power to enable the lawnmower's mowing function. The cutting assembly is configured with two or three sets.

[0025] In one embodiment, the cutting assembly includes a blade disc, mowing elements, and a cutting motor. The cutting motor is controlled by a control button on the operating assembly 300. The mowing elements are used to cut vegetation such as grasses when rotating at high speed. For example, the mowing elements are blades used to cut vegetation on a lawn. The blade disc forms a mowing space to accommodate the mowing elements, which are at least partially located within the mowing space. In some embodiments, the number of mowing elements can be two, and correspondingly, the number of cutting motors can also be two. The two cutting motors independently drive the two mowing elements. In some embodiments, the number of mowing elements can be three, and correspondingly, the number of cutting motors can also be three. The three cutting motors independently drive the three mowing elements.

[0026] Of course, the power output component 500 can also be detached from the outdoor work vehicle. In some embodiments, it is understood that the power output component 500 can be replaced with other components to meet the usage needs of different garden operations. Therefore, the outdoor garden lawnmower can not only cut vegetation, but the cutting component can also be replaced with functional parts such as snow shoveling, snow sweeping, snow blowing, and rinsing. Those skilled in the art should be able to adapt various functional parts without creative effort, and all of the above should be included within the protection scope of this embodiment.

[0027] When the cutting components are replaced with functional components such as snow shovel, snow sweeper, and snow blower, the power supply device 200 of the outdoor operation vehicle of this application can also adapt to a relatively cold environment and provide power to the aforementioned functional components such as snow shovel, snow sweeper, and snow blower.

[0028] The walking assembly 600 includes walking wheels mounted on the frame 100 and a walking motor for driving the walking wheels. The walking wheels are located on both sides of the frame 100, so that the center of gravity of the outdoor work vehicle is kept within the frame 100, thereby reducing the probability of the outdoor work vehicle overturning when walking.

[0029] In one embodiment, the number of wheels is set to four, including two front wheels 601 and two rear wheels 602. The front wheels 601 can be omnidirectional wheels. A drive motor is connected to and drives the rear wheels 602 to rotate. Both rear wheels 602 are matched with drive motors. The speeds of the two drive motors can be the same or different. When the user is driving the outdoor work vehicle straight, the speeds of the two drive motors are approximately the same; when the user is driving the outdoor work vehicle turning, the speeds of the two drive motors are different, and the outdoor work vehicle turns towards the side with the lower speed drive motor. In some embodiments, the diameter of the front wheels 601 is smaller than the diameter of the rear wheels 602.

[0030] In one embodiment, the power supply device 200 is used at least to power an outdoor work vehicle. The power supply device 200 includes a battery compartment where a first type of battery pack or a second type of battery pack can be installed, or both can be installed simultaneously. The first type of battery pack and the second type of battery pack can be detachably installed within the battery compartment. The first type of battery pack and the second type of battery pack can also be detached from the battery compartment to power other tools.

[0031] Combination Figure 1 , Figure 2 and Figure 7 In some embodiments, the outdoor work vehicle of this application includes a frame 100, a walking assembly 600, a cutting assembly, a power supply device 200, a power management device 219, and a protective component 105. The frame 100 extends along a first direction 106; the walking assembly 600 is disposed on the frame 100 and configured to support the movement of the outdoor work vehicle; the cutting assembly is disposed on the frame 100 and configured to cut vegetation; the power supply device 200 is used to supply power to the outdoor work vehicle at least; the power management device 219 is disposed below the power supply device 200 and is used to control the charging or discharging of the power supply device 200 at least; the protective member 105 is disposed below the power management device 219 and is used to protect the power management device 219 at least. An air inlet 1051 and an air outlet 1052 are formed between the protective member 105 and the power management device 219, and an airflow channel 1053 is located between the air inlet 1051 and the air outlet 1052. Debris generated during the operation of the outdoor work vehicle can enter the airflow channel from the air inlet 1051 and be discharged from the air outlet 1052.

[0032] Combination Figure 2 and Figure 6 In some embodiments, along the first direction 106, the midpoint of the line connecting the frontmost and rearmost ends of the protective member 105 is defined as the center point 107. A straight line 108 passing through the center point 107 in the horizontal direction divides the protective member 105 into a second protective part 1055 near the front of the vehicle and a first protective part 1054 near the rear of the vehicle. The projected area of ​​the first protective part 1054 in the vertical direction is smaller than the projected area of ​​the second protective part 1055. The closer the first protective part 1054 is to the rear of the vehicle, the smaller its projected area in the vertical direction, which is more conducive to the discharge of grass clippings.

[0033] In some embodiments, the ratio of the projected areas of the second protective portion 1055 and the first protective portion 1054 in the vertical direction is 1.1 to 2. In some embodiments, the ratio of the projected areas of the second protective portion 1055 and the first protective portion 1054 in the vertical direction is 1.1, 1.3, 1.5, 1.8, or 2.

[0034] It should be noted that in order to form an air intake airflow between the protective component 105 and the power management device 219, the area of ​​the second protective part 1055 of the protective component 105 is generally set to be relatively large. Since there is a space between the protective component 105 and the power management device 219, the airflow speed in the space is faster than that outside when the vehicle is in motion, which is beneficial for heat dissipation of the power management device 219. However, in order to facilitate the removal of grass, the area of ​​the first protective part 1054 is set to be relatively small.

[0035] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the protective component 105 is provided with a through hole 10541, which is located in the first protective part 1054. The through hole 10541 can discharge grass and guide airflow. Since the debris generated by the lawnmower during operation moves from the front to the rear of the frame 100, when the debris enters the airflow channel 1053 between the protective component 105 and the power management device 219, it can be discharged not only from the air outlet 1052 of the airflow channel 1053, but also from the through hole 10541 on the protective component 105. This can speed up the grass discharge and increase the airflow rate, which helps to dissipate heat from the power management device 219.

[0036] like Figure 2 As shown, in some embodiments, the through hole 10541 is provided on the protective member 105 near the rear of the frame 100 to facilitate the removal of grass clippings.

[0037] like Figure 2 As shown, in some embodiments, the frame 100 includes a longitudinal beam disposed along a first direction 106 and a crossbeam connected to the longitudinal beam, and the protective member 105 is connected to the longitudinal beam and the crossbeam. This arrangement makes the installation of the protective member 105 on the frame 100 more stable.

[0038] like Figure 2 and Figure 3As shown, in some embodiments, the frame 100 includes a first support portion 101 configured to support a seat 400, a second support portion 103 configured to support a power supply device 200, and a connecting portion 102 connecting the first support portion 101 and the second support portion 103. The first support portion 101 and the second support portion 103 have different heights, and a protective member 105 is connected to the second support portion 103 and the connecting portion 102. In some embodiments, the second support portion 103 is generally horizontally arranged, the connecting portion 102 is inclined, and the protective member 105 includes a generally horizontally arranged first protective member and an inclined second protective member 1055. The first protective member 1054 is connected to the second support portion 103, and the second protective member 1055 is connected to the connecting portion 102. In this embodiment, the frame 100 is configured with portions of different heights, and the protective member 105 is adaptively attached to different height positions of the frame 100, which makes the protective member 105 more securely fitted to the frame 100 at these positions.

[0039] Combination Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the first protective part 1054 is provided with a first connecting hole 10543, and the first protective part 1054 is fixed to the second supporting part 103 of the frame 100 by bolts provided in the first connecting hole 10543. The second protective part 1055 is provided with a second connecting hole 10551, and the second protective part 1055 is fixed to the connecting part 102 of the frame 100 by bolts provided in the second connecting hole 10551.

[0040] Combination Figure 1 and Figure 2 In some embodiments, the walking assembly 600 includes a rear walking wheel 602 located at the rear of the frame 100 and rotating about a first axis 6021, and a front walking wheel 601 located at the front of the frame 100 and rotating about a second axis 6011. A protective member 105 is located above at least one of the first axis 6021 and the second axis 6011. In some embodiments, the protective member 105 is located above one of the first axis 6021 and the second axis 6011; in other embodiments, the protective member 105 is located above both the first axis 6021 and the second axis 6011.

[0041] Combination Figure 1 and Figure 2 In some embodiments, along the first direction 106, the protective element 105 is located between the first axis 6021 and the rear end of the outdoor work vehicle.

[0042] In some embodiments, the protective element 105 is a plate-like structure, and the protective element 105 is made of metal. The metal protective element 105 has higher strength and a longer service life.

[0043] Combination Figure 1 , Figure 2 and Figure 4 This application also provides an outdoor work vehicle, including a frame 100, a running gear 600, a cutting assembly, a power supply unit 200, a power management device 219, and a protective member 105. The frame 100 includes longitudinal beams arranged along a first direction 106 and crossbeams connected to the longitudinal beams; the running gear 600 is disposed on the frame 100 and configured to support the movement of the outdoor work vehicle; the cutting assembly is disposed on the frame 100 and configured to cut vegetation; the power supply unit 200 is used to at least supply power to the outdoor work vehicle; the power management device 219 is disposed below the power supply unit 200 and is used at least to control the charging or discharging of the power supply unit 200; the protective member 105 is disposed below the power management device 200. Below 9, the protective cover is used to protect at least the power management device 219. An air inlet 1051 and an air outlet 1052 are formed between the protective component 105 and the power management device 219, as well as an airflow channel 1053 located between the air inlet 1051 and the air outlet 1052. Debris generated during the operation of the outdoor work vehicle can enter the airflow channel from the air inlet 1051 and be discharged from the air outlet 1052. The protective component 105 is connected to the longitudinal beam and the cross beam. This arrangement makes the installation of the protective component 105 on the frame 100 more stable.

[0044] like Figure 2 As shown, in some embodiments, a hook 104 for towing other mobile devices is provided on the crossbeam at the rear of the frame 100. The hook 104 occupies the outer and inner space of the crossbeam. The protective member 105 is provided with a clearance part 10542 to avoid the hook 104, so that the installation of the protective member 105 will not interfere with the hook 104, which is beneficial to improving the assembly efficiency of the entire outdoor operation setup.
