[0046] The recess is arranged outside the rear part of the power management device, and the third through hole is arranged in a direction away from the power management device, so that liquid or hard objects entering the third through hole cannot directly splash or rebound onto the power management device, thereby preventing damage.

[0047] The existing outdoor working equipment is provided with a storage box for storing tools or other objects, but the arrangement is unreasonable. Some outdoor working equipment is provided with a large drag bucket at the tail of the vehicle frame, which occupies a large space of the whole vehicle, is not conducive to the layout of other components, especially large battery packs, and limits the endurance of the outdoor working equipment. Some outdoor working equipment is provided with a groove on the covering member on both sides of the vehicle for storing a water cup, a digital product or the like, and general tools cannot be placed in the groove. As a mechanical equipment, it is necessary for the outdoor working equipment to carry tools, and therefore the above designs have certain limitations.

[0048] Therefore, it is necessary to provide an improved storage box for outdoor working equipment to overcome the defects in the prior art.

[0049] In a second aspect, the technical scheme adopted by the present application to solve the problems in the prior art is: a storage box for outdoor working equipment, wherein the outdoor working equipment comprises:

[0050] a vehicle frame, the vehicle frame being provided with: a walking assembly configured to support the outdoor working equipment to walk; a power output assembly configured to perform outdoor work; a seat configured for a user to sit on; a power supply device configured to supply power to the outdoor working equipment; and at least one storage box for storing equipment, the storage box being located between the seat and the power supply device, and the storage box, the seat and the power supply device at least partially overlapping in the direction of travel of the outdoor working equipment.

[0055] Further improvement is that a box cover is arranged at the opening of the storage box.

[0056] Further improvement is that the storage box is detachably mounted on the frame.

[0057] Further improvement is that the storage box is configured to mount a battery pack to power the outdoor working equipment.

[0058] Further improvement is that the volume of the storage box is 3L-20L.

[0059] Further improvement is that a charging port is arranged on the storage box.

[0060] Compared with the prior art, the present application has the following beneficial effects:

[0061] The storage box is arranged close to the power supply device, and an extension plate is arranged on each side of the storage box, and the extension plates on the two sides are overlapped with the power supply device to form a containing cavity. Since the battery compartment of the present application is provided with a cooling fan, the containing cavity is arranged to form a ventilation channel to facilitate the heat dissipation of the battery pack in the battery compartment, and the wire harness connected with the cooling fan can also be accommodated in the containing cavity to protect the cooling fan and the wire harness.

[0062] In addition, the volume of the storage box is 3L-20L, and the space is reasonably arranged, which can meet the storage of general tools and will not occupy too much space of the outdoor working equipment.

[0063] The frame of the outdoor working equipment is an important part of the whole vehicle, which plays a role in supporting the parts of the whole vehicle and fixedly mounting other parts. Considering the different structures of the layout of the whole vehicle at different positions, the roles of different parts of the frame are also different, and the design of the frame needs to be more comprehensive.

[0064] Most of the existing frames are designed as horizontal structures, especially the outdoor working equipment with battery pack as the energy source. In order to improve the endurance of the outdoor working equipment, the volume of the battery pack is often increased. If the frame is still arranged at the original height, the center of gravity of the whole vehicle will be unstable, which is easy to cause the rollover of the vehicle.

[0065] Therefore, it is necessary to provide an improved frame for outdoor working equipment to overcome the defects in the prior art.

[0066] The third aspect of the present application adopts the technical solution of an outdoor work equipment vehicle frame, which comprises a vehicle frame, wherein the vehicle frame is provided with a seat for a user to sit on, a walking assembly for supporting the outdoor work equipment to walk, the walking assembly comprising front walking wheels and rear walking wheels, a power output assembly for performing outdoor work, and a power supply device for supplying power to the outdoor work equipment, the power supply device comprising first type battery packs and second type battery packs with different capacitances; the vehicle frame comprises a first bearing part for bearing at least the seat and a second bearing part for bearing at least the power supply device; and the height of the first bearing part is different from that of the second bearing part.

[0067] Further improvement is that the height of the first bearing part is higher than that of the second bearing part.

[0068] Further improvement is that the second bearing part is provided with a hanger for towing the outdoor work equipment, and the distance between the hanger and the axis of the rear walking wheels in the up-down direction is 200mm-380mm.

[0069] Further improvement is that the vehicle frame is provided with a power supply fixing plate, which is connected to the connecting part and the second bearing part in an inclined manner.

[0070] Further improvement is that the height of the connecting part is higher than that of the second bearing part, one end of the power supply fixing plate is lapped on the connecting part, and the other end is lapped on the second bearing part, so that the bottom surface of the power supply fixing plate can be inclined towards the advancing direction of the outdoor work equipment, and the opening of the battery compartment fixed on the power supply fixing plate can be inclined towards the rear of the outdoor work equipment.

[0071] Further improvement is that the height of the lower surface of the first bearing part from the ground is 279mm-381mm.

[0072] Further improvement is that the ratio of the height of the lower surface of the first bearing part from the ground to the radius of the front walking wheels is 2-3 times.

[0073] Further improvement is that the height of the lower surface of the second bearing part from the ground is 228mm-366mm.

[0074] Further improvement is that the ratio of the height of the lower surface of the second bearing part from the ground to the radius of the rear walking wheels is 1-1.2 times.

[0075] Further improvement is that the height difference between the first bearing part and the second bearing part is 100mm-150mm.

[0076] Further improvement scheme is that the connecting part is further connected to the first bearing part and the second bearing part, the angle between the connecting part and the first bearing part is 10-30 degrees, and the angle between the connecting part and the second bearing part is 10-30 degrees.

[0077] Further improvement scheme is that the length ratio of the first bearing part, the connecting part and the second bearing part along the extension direction of the frame is (5-8):(6-10):(30-40).

[0078] Compared with the prior art, the present application has the following beneficial effects:

[0079] The height of the second bearing part is lower than that of the first bearing part, which is beneficial to reduce the gravity center of the entire outdoor working equipment, so that the outdoor working equipment is more stable during operation.

[0080] When the upper part has limited height, the tail part of the frame where the power supply device is installed is designed to be sunken, so that the volume of the battery compartment of the power supply device can be increased to a greater extent in the limited space, so that the battery compartment can accommodate a large-capacity battery pack with a larger volume, thereby improving the endurance of the outdoor working equipment.

[0081] The outdoor working equipment, especially the new energy mower, is widely used in the fields of trimming lawns, vegetation and the like.

[0082] Since the battery core of the new energy battery pack generates heat during charging and discharging, and due to the blocking of the battery pack shell, the heat dissipation effect inside the battery pack is limited, which will cause the temperature inside the battery pack to rise continuously, and thus may cause the battery pack to swell, leak and even explode due to overheating, posing a safety hazard. In addition, the working climate environment of the new energy mower is complex and diverse, and when working in a relatively cold environment, if the temperature is low, it will affect the discharging effect of the battery pack and the endurance of the entire mower. Therefore, it is necessary to cool the battery pack when the temperature inside the battery pack is high and to heat the battery pack when the temperature inside the battery pack is low.

[0083] In addition, in order to improve the adaptability of the mower to different types of battery packs, some mowers are designed to be able to accommodate battery packs of different sizes or different capacities. Since energy needs to be obtained from the battery pack for heat dissipation and heating treatment, and different types of battery packs require different heat dissipation or cooling treatment, if the treatment is not reasonable, it will cause unreasonable use of battery pack power and affect the endurance of the battery pack.

[0084] Therefore, it is necessary to provide an improved outdoor working equipment to overcome the defects of the prior art.

[0085] In a fourth aspect, the present application adopts the technical scheme that an outdoor operation equipment comprises a vehicle frame, a walking assembly arranged on the vehicle frame and used for supporting the outdoor operation equipment to walk, and a power supply device arranged on the vehicle frame and used for supplying power to the outdoor operation equipment, wherein the power supply device comprises a power supply unit capable of being detached from the outdoor operation equipment and used for supplying power to other tools, a battery compartment used for assembling and electrically connecting with the power supply unit, and a plurality of temperature adjusting assemblies arranged on two oppositely arranged side plates of the battery compartment respectively, and the plurality of temperature adjusting assemblies are used for exchanging heat between the inside of the power supply unit and the outside air.

[0086] Further improvement schemes are that the power supply unit comprises a first type battery pack and / or a second type battery pack; when the number of the first type battery packs assembled in the battery compartment is x, the number of the temperature adjusting assemblies configured to adjust the temperature of the first type battery packs is x; and when the number of the second type battery packs assembled in the battery compartment is y, the number of the temperature adjusting assemblies configured to adjust the temperature of the second type battery packs is 2y.

[0087] Further improvement schemes are that the temperature adjusting assemblies are arranged on the two oppositely arranged side plates of the battery compartment, and the temperature adjusting assemblies arranged on one of the side plates are arranged one by one corresponding to the temperature adjusting assemblies arranged on the other side plate.

[0089] Further improvement schemes are that the electric capacity of the first type battery pack is greater than or equal to 90Wh and less than or equal to 1000Wh, and the electric capacity of the second type battery pack is greater than or equal to 1000Wh and less than or equal to 4000Wh.

[0090] The application also provides an outdoor working device, comprising: a vehicle frame; a power supply device arranged on the vehicle frame, the power supply device being used at least for supplying power to the outdoor working device, the power supply device comprising: a first type battery pack and / or a second type battery pack; a battery compartment, the first type battery pack and the second type battery pack being respectively detachably installed in the battery compartment; and a plurality of temperature adjusting assemblies for adjusting the temperature of the first type battery pack and / or the second type battery pack, wherein the plurality of temperature adjusting assemblies are used at least for adjusting the temperature of the first type battery pack and / or the second type battery pack with an internal temperature in a first range value, and do not adjust the temperature of the first type battery pack and / or the second type battery pack with an internal temperature in a normal range value.

[0091] Further improvement is that when the number of the first type battery pack with an internal temperature in the first range value is m, the number of the temperature adjusting assemblies configured for adjusting the temperature of m first type battery packs is m.

[0092] Further improvement is that when the number of the first type battery pack with an internal temperature in the second range value is m, the number of the temperature adjusting assemblies configured for adjusting the temperature of m first type battery packs is at least m+1 and at most all the temperature adjusting assemblies on the outdoor working device.

[0095] Compared with the prior art, the application has the following beneficial effects:

[0096] The application processes the battery packs with different types of temperature abnormalities in a targeted manner, and does not process the battery packs with normal temperature, since the electric energy required for processing the temperature abnormalities also comes from the battery packs, such a setting can save electric energy and improve the endurance of the battery packs.

[0097] The battery compartment is provided with a plurality of temperature adjusting assemblies, the temperature adjusting assemblies process the first type battery packs with a temperature in the first range value in a one-to-one manner and process the second type battery packs with a temperature in the first range value in a two-to-one manner, so that the temperature adjusting processing can be performed according to the actual needs of the battery packs, and unnecessary waste of the energy of the battery packs is avoided.

[0098] In addition, when the temperature is in the second range, the number of temperature regulating components for processing the first type of battery pack is more than the number of battery packs inserted into the lawn mower, and at most all the temperature regulating components on the lawn mower can be used to regulate the temperature of the first type of battery pack; when the temperature is in the second range, the number of temperature regulating components for processing the second type of battery pack is more than twice the number of battery packs inserted into the lawn mower, and at most all the temperature regulating components on the lawn mower can be used to regulate the temperature of the first type of battery pack, so that the first type of battery pack or the second type of battery pack can quickly reach the temperature regulating purpose.

[0099] Outdoor working equipment, especially outdoor garden lawn mower, many power management devices of the lawn mower do not have protective plates, and generally rely on the sealing mode of the power management device itself to prevent water by installing the power management device in a position not easy to enter water. When washing the car with a high-pressure water gun, water may splash in the position not easy to enter water; after a long time, the sealing element of the power management device itself will age, the sealing effect will decrease, and the power management device will have the risk of entering water. Although some power management devices use flat plates for protection, they do not have optimized effects on heat dissipation of the power management device, and even dust accumulation may cause poor heat dissipation of the power management device, affecting the use effect and service life of the power management device.

[0100] Therefore, it is necessary to provide an improved outdoor working equipment to overcome the defects in the prior art.

[0101] In a fifth aspect, the technical scheme adopted by the present application to solve the problems in the prior art is: an outdoor working equipment, comprising:

[0102] a vehicle frame, wherein the vehicle frame is provided with:

[0107] Further improvement is that the lower surface of the protective cover comprises a first inclined surface arranged obliquely along the forward direction of the outdoor working equipment, and the first and second through holes are arranged at the upper end and the lower end of the first inclined surface, respectively.

[0108] When the outdoor working equipment is advancing, the speed of airflow flowing through the first through hole is less than the speed of airflow flowing through the second through hole outside the protective cover, wherein at least part of the debris entering the protective cover through the first through hole can flow out from the second through hole under the action of negative pressure.

[0109] Further improvement is that the protective cover is further provided with a third through hole.

[0110] When the outdoor working equipment is advancing, the speed of airflow flowing through the second through hole is less than the speed of airflow flowing through the third through hole outside the protective cover, wherein at least part of the debris located in the protective cover can flow out from the third through hole under the action of negative pressure.

[0111] Further improvement is that the protective cover is obliquely arranged, and the lower surface of the protective cover is obliquely arranged towards the advancing direction of the outdoor working equipment.

[0123] The outdoor working equipment, especially the new energy mower, is widely used in the fields of trimming lawns, vegetation and the like as a kind of lawn machinery.

[0124] Since the charging and discharging of the battery pack required by the new energy mower are controlled by the power management device, and the power management device of many mowers is far away from the battery pack, a long wire harness is required to connect the two when connecting them, and the power management device is connected to other electrical devices, which makes the wire harness connected to the power management device multiple and messy, and occupies more space on the outdoor working equipment, which is not conducive to the overall layout of the outdoor working equipment.

[0125] Therefore, it is necessary to provide an improved outdoor working equipment to overcome the defects in the prior art.

The three cutting motors independently drive the three grass cutting elements, respectively.

[0278] Of course, the power output assembly 500 can also be detached from the outdoor working device. In some embodiments, it can be understood that the power output assembly 500 can be replaced by other assemblies to meet the use requirements of different garden operations. Therefore, the outdoor garden mower can not only cut vegetation, but also replace the cutting assembly with snow shoveling, snow sweeping, snow blowing, and flushing functional components. Those skilled in the art should be able to adaptively replace various functional components without creative labor, and all of the above should be included in the protection scope of the present embodiment.

[0279] When the cutting assembly is replaced by snow shoveling, snow sweeping, snow blowing, and other functional components, the power supply device 200 of the outdoor working device of the present application can also adapt to a relatively cold environment to power the above-mentioned snow shoveling, snow sweeping, snow blowing, and other functional components.

[0280] The walking assembly 600 comprises walking wheels arranged on the vehicle frame 100 and walking motors for driving the walking wheels. The walking wheels are arranged on both sides of the vehicle frame 100, so that the center of gravity of the outdoor working device is kept within the vehicle frame 100, thereby reducing the probability of the outdoor working device rolling over when walking.

[0281] In an embodiment, the number of walking wheels is set to 4, including 2 front walking wheels 601 and 2 rear walking wheels 602. The front walking wheels 601 can be universal wheels, and the walking motors are connected with the rear walking wheels 602 and drive the rear walking wheels 602 to rotate. The two rear walking wheels 602 are matched with the walking motors, and the rotation speeds of the two walking motors can be the same or different. When the user drives the outdoor working device straight, the rotation speeds of the two walking motors are substantially the same. When the user drives the outdoor working device to turn, the rotation speeds of the two walking motors are different, and the outdoor working device turns to the side with the lower rotation speed of the walking motor. In some embodiments, the diameter of the front walking wheel 601 is smaller than the diameter of the rear walking wheel 602.

[0282] In an embodiment, please refer to FIG. 2, FIG. 3 and FIG. 4, the power supply device 200 is used for supplying power to the outdoor working equipment, the power supply device 200 comprises a battery compartment 201, the first type battery pack 205 or the second type battery pack 206, or both the first type battery pack 205 and the second type battery pack 206 are installed in the battery compartment 201. The first type battery pack 205 and the second type battery pack 206 are respectively installed in the battery compartment 201 in a detachable manner.

[0283] The first type battery pack 205 and the second type battery pack 206 can also be detached from the battery compartment 201 to supply power to other tools.

[0284] Please refer to FIG. 2, FIG. 3 and FIG. 4, the battery compartment 201 is further provided with a plurality of temperature adjusting assemblies 203, the plurality of temperature adjusting assemblies 203 are configured to adjust the temperature of the first type battery pack 205 and / or the second type battery pack 206 by obtaining the power of the battery pack on the outdoor working equipment. In an embodiment, the temperature adjusting operation comprises two modes of heating and cooling, and in this application, the first type battery pack 205 and / or the second type battery pack 206 can be heated or cooled according to actual needs.

[0285] Of course, the plurality of temperature adjusting assemblies 203 can obtain power from the first type battery pack 205 or the second type battery pack 206 in the battery compartment 201, or from other battery packs that can supply power on the outdoor working equipment.

[0286] Please refer to FIG. 2, FIG. 3 and FIG. 4, specifically, when the first type battery pack 205 and the second type battery pack 206 need to be cooled, the temperature adjusting assembly 203 is an air flow generator 2031 capable of generating air flow, which can be a cooling fan, used for cooling the first type battery pack 205 and the second type battery pack 206.

[0287] When the first type battery pack 205 and the second type battery pack 206 need to be heated, the temperature adjusting assembly 203 is an air flow generator 2031 capable of generating air flow and a heater capable of generating heat, the air flow generator 2031 is used to blow the heat generated by the heater to the first type battery pack 205 and the second type battery pack 206 for heating treatment.

[0288] As shown in FIG. 2 and FIG. 4, in an embodiment, when the number of the first type battery pack 205 installed in the battery compartment 201 is x, the number of the temperature adjusting assembly 203 configured to adjust the temperature of the first type battery pack 205 is x, specifically, the number of the temperature adjusting assembly 203 configured to adjust the temperature of the x first type battery pack 205 at any time is x.

[0289] In an embodiment, when the internal temperature of m first-type battery packs 205 among the x first-type battery packs 205 is higher than the normal range value and within the first range value, the power management device 219 starts the m temperature adjusting assemblies 203 to perform temperature adjusting process on the m first-type battery packs 205 whose internal temperature is within the first range value until the temperature is adjusted to the normal range value.

[0290] In this way, the number of first-type battery packs 205 is matched with the number of temperature adjusting assemblies 203 in a one-to-one manner. When the temperature of the first-type battery pack 205 during charging and discharging is different from the normal range value, but the temperature adjusting demand is limited, one temperature adjusting assembly 203 can meet the heat dissipation or heating demand of the first-type battery pack 205. When the temperature is within the normal range value, the first-type battery pack 205 does not need to be adjusted. Since the energy source of the temperature adjusting assembly 203 is also from the battery pack, the power of the battery pack can be saved, and the endurance of the battery pack can be improved.

[0291] Further, the temperature range of the first range value can be higher than the normal range value, or lower than the normal range value. When the temperature range of the first range value is higher than the normal range value, the temperature adjusting assembly 203 only starts the air flow generator 2031 to dissipate heat for the first-type battery pack 205, so that the temperature in the first-type battery pack 205 is quickly reduced to the normal range value, which is helpful for charging or discharging of the battery pack. When the temperature range of the first range value is lower than the normal range value, the temperature adjusting assembly 203 starts the air flow generator 2031 and the heater, and the air flow generator 2031 blows the heat generated by the heater to the first-type battery pack 205 to heat the first-type battery pack 205, so as to increase the temperature in the first-type battery pack 205 to the normal range value, which is helpful for charging or discharging of the battery pack.

[0292] It should be understood that the heater (not shown in the figure) can be a heating wire or other components capable of generating heat, and the heater is arranged corresponding to the air port of the air flow generator 2031.

[0293] In an embodiment, when the one-to-one heat dissipation mode cannot meet the temperature adjusting demand of the first-type battery pack 205, i.e., when the number of first-type battery packs 205 whose internal temperature is within the second range value is m, the number of temperature adjusting assemblies 203 configured to adjust the temperature of the m first-type battery packs 205 is at least m+1 and at most all the temperature adjusting assemblies 203 on the outdoor working device. Specifically, the power management device 219 adjusts the work of the temperature adjusting assemblies 203 according to the temperature in the first-type battery pack 205. When the temperature in the first-type battery pack 205 is within the second range value, the power management device 219 starts multiple temperature adjusting assemblies 203 to perform temperature adjusting process on the first-type battery pack 205, so as to ensure the normal charging and discharging demand of the first-type battery pack 205.

[0294] It is to be understood that when the temperature in the first type battery pack 205 or the second type battery pack 206 is in the first range value and higher than the normal range value, the second range value is higher than the first range value, the first type battery pack 205 or the second type battery pack 206 needs to be cooled; when the temperature in the first type battery pack 205 or the second type battery pack 206 is in the first range value and lower than the normal range value, the second range value is lower than the first range value, the first type battery pack 205 or the second type battery pack 206 needs to be heated.

[0295] In a preferred embodiment, the electric capacity of the first type battery pack 205 is greater than or equal to 90 Wh and less than 1000 Wh, and the electric capacity of the first type battery pack 205 is preferably 90 Wh, 600 Wh or 999 Wh.

[0296] As shown in FIG. 3 and FIG. 4, in an embodiment, when the number of the second type battery pack 206 loaded into the battery compartment 201 is y, the number of the temperature adjusting assembly 203 configured to adjust the temperature of the second type battery pack 206 is 2y. In this way, the number of the second type battery pack 206 and the number of the temperature adjusting assembly 203 are set in a one-to-two matching manner, which is set in the case that one temperature adjusting assembly 203 cannot meet the cooling or heating demand of one second type battery pack 206.

[0297] In a specific embodiment, the second type battery pack 206 has a large electric capacity, and the electric capacity of the second type battery pack 206 is usually greater than or equal to 1000 Wh and less than or equal to 4000 Wh, and the electric capacity of the second type battery pack 206 is preferably 1000 Wh, 2500 Wh and 4000 Wh.

[0298] In an embodiment, when the number of the internal temperature of the y second type battery pack 206 loaded into the battery compartment 201 is in the first range value is n, the power management device 219 will start 2n temperature adjusting assemblies 203 to adjust the temperature of the n second type battery pack 206 with the internal temperature in the first range value.

[0299] In this way, the number of the second type battery pack 206 and the number of the temperature adjusting assembly 203 are set in a one-to-two matching manner, which is to meet the cooling or heating demand of one second type battery pack 206 by two temperature adjusting assemblies 203 in the case that one temperature adjusting assembly 203 cannot meet the cooling or heating demand of one second type battery pack 206 when the second type battery pack 206 generates heat during charging and discharging, and the second type battery pack 206 with the temperature in the normal range value does not need to be adjusted. Since the energy source of the temperature adjusting assembly 203 also comes from the battery pack, in the case of meeting the temperature adjusting demand, the less the number of the started temperature adjusting assembly 203, the more the battery pack energy is saved, and the longer the battery pack endurance is improved.

[0300] In an embodiment, when the internal temperature of the y second-type battery packs 206 loaded in the battery compartment 201 is in the second range of values for a number n, the power management device 219 activates at least 2n+1 temperature regulating assemblies 203 to regulate the temperature of the n second-type battery packs 206 with the internal temperature in the second range of values, and at most all the temperature regulating assemblies 203 on the outdoor working equipment to regulate the temperature of the n second-type battery packs 206 with the internal temperature in the second range of values.

[0392] As shown in FIG. 20, in a preferred embodiment, the application further comprises a connecting part 102 connecting the first bearing part 101 and the second bearing part 103, the connecting part 102 is arranged obliquely, the angle α4 between the connecting part 102 and the first bearing part 101 is 10°-30°, the angle α4 between the connecting part 102 and the first bearing part 101 is preferably 10°, 20° and 30°, the angle α5 between the connecting part 102 and the second bearing part 103 is 10°-30°, and the angle α5 between the connecting part 102 and the second bearing part 103 is preferably 10°, 20° and 30°.

[0393] Of course, the first bearing part 101 and the second bearing part 103 are arranged horizontally, and the connecting part 102 can be connected with the first bearing part 101 and the second bearing part 103 perpendicularly.

[0395] In an embodiment, the first bearing part 101, the second bearing part 103 and the connecting part 102 are integrated, and the integrated frame 100 has better strength than the split frame 100, and saves the assembly time of the entire outdoor working equipment.

[0396] In another embodiment, when the height of the second bearing part 103 is higher than the height of the first bearing part 101, it is beneficial to improve the height of the tail of the frame 100, and when the outdoor working equipment is in a rugged area, especially on a road surface that needs to repeatedly go up and down, the higher height of the tail of the frame 100 improves the departure angle of the tail of the frame 100, which is beneficial to improve the passing ability of the outdoor working equipment.

[0397] As shown in FIG. 22, FIG. 28-32, in an embodiment, the outdoor working equipment of the present application comprises a frame 100; a power supply device 200 is arranged on the frame 100, at least for supplying power to the outdoor working equipment; a power management device 219 is arranged below the power supply device 200, the power management device 219 is at least for controlling the charging or discharging of the power supply device 200; a protective cover 106 is at least for covering the power management device 219, the protective cover 106 is arranged below the power management device 219, and the protective cover 106 is provided with a first through hole 108 and a second through hole 110 at least for heat dissipation. The power management device 219 is arranged below the power supply device 200, and the protective cover 106 is arranged to protect the power management device 219 from damage caused by liquid, hard objects, etc. Since the power management device 219 generates heat during operation, the first through hole 108 and the second through hole 110 are arranged on the protective cover 106 for heat dissipation of the power management device 219.

[0398] As shown in FIG. 1, FIG. 30-31, the cutting assembly of the outdoor working equipment of the present application is arranged below the frame 100, and the power management device 219 is also arranged below the frame 100 and behind the cutting assembly. When the outdoor working equipment moves forward and cuts vegetation, debris and other impurities will be thrown backward, and some debris will enter the protective cover 106 through the first through hole 108 or the second through hole 110. Over time, this will cause accumulation and affect the heat dissipation effect of the power management device 219.

[0399] To solve the above problems, in an embodiment of the present application, a part of the lower surface of the protective cover 106, especially the part close to the cutting assembly, is designed as a first inclined surface 107 arranged obliquely along the forward direction of the outdoor working equipment, and the first through hole 108 and the second through hole 110 are arranged at the upper end and the lower end of the first inclined surface 107, respectively. When the outdoor working equipment moves forward, the speed of airflow flowing through the first through hole 108 is less than the speed of airflow flowing through the second through hole 110 outside the protective cover 106, and at least part of the debris entering the protective cover 106 through the first through hole 108 can flow out of the second through hole 110 under the action of negative pressure. In this way, the ventilation effect of the protective cover 106 is ensured, and the debris entering the protective cover 106 through the first through hole 108 can be effectively discharged from the protective cover 106 through the second through hole 110 under the action of negative pressure according to Bernoulli's principle.

[0400] As shown in FIG. 30, in an embodiment, the first inclined surface 107 has an angle a1 of 40°-85° with the horizontal direction, and the first inclined surface 107 preferably has an angle a1 of 40°, 52° and 85° with the horizontal direction. It should be understood that the greater the angle a1 of the first inclined surface 107 with the horizontal direction, the greater the flow rate difference of the flow through the first through hole 108 and the second through hole 110, and thus the greater the pressure difference generated, and the better the negative pressure effect generated at the second through hole 110, and the better the effect of discharging the debris.

[0401] As shown in FIG. 31, in an embodiment, the first through hole 108 has a hole area of 60mm 2 -80mm 2 , and the first through hole 108 preferably has a hole area of 60mm 2 , 70mm 2 and 80mm 2 .

[0402] As shown in FIG. 31, the second through hole 110 has a hole area of 3-50 times the hole area of the first through hole 108, and the second through hole 110 preferably has a hole area of 3, 30 and 50 times the hole area of the first through hole 108. Designing the first through hole 108 to have a small hole area can reduce the debris entering the protective cover 106 as much as possible while ensuring ventilation and heat dissipation, and designing the second through hole 110 to be larger than the first through hole 108 helps to discharge the debris entering the protective cover 106 through the larger second through hole 110.

[0403] As shown in FIG. 30 and FIG. 31, in an embodiment, the protective cover 106 is formed with a groove 115 capable of collecting debris, and the second through hole 110 is located on the groove wall of the groove 115. Specifically, the groove 115 includes a second inclined surface 109 connected with the first inclined surface 107, the lower end of the second inclined surface 109 is connected with the lower end of the first inclined surface 107, and the second through hole 110 is located at the connection between the first inclined surface 107 and the second inclined surface 109. The design of the second inclined surface 109 helps to shield the debris entering the protective cover 106, so that the debris entering the groove 115 can move as much as possible in the direction of the groove 115, reducing the movement towards the rear of the protective cover 106.

[0404] As shown in FIG. 30, in an embodiment, the second inclined surface 109 has an angle a2 of 0°-60° with the horizontal direction, and the second inclined surface 109 preferably has an angle a2 of 0°, 30° and 60° with the horizontal direction. The greater the angle a2 of the second inclined surface 109 with the horizontal direction, the better the blocking effect on the debris, which can reduce the movement of the debris towards the rear of the protective cover 106 as much as possible.

[0405] Please refer to FIG. 30 and FIG. 31, in an embodiment, in order to discharge the debris which is not discharged from the second through hole 110 and moves to the rear part of the protective cover 106, the rear part of the protective cover 106 of the present application is further provided with a third inclined surface 111 which is connected with the second inclined surface 109 and is inclined along the advancing direction of the outdoor working equipment, the upper end of the third inclined surface 111 is connected with the upper end of the second inclined surface 109, and the lower end of the third inclined surface 111 is provided with a third through hole 114. When the outdoor working equipment advances, the speed of the airflow flowing through the second through hole 110 is less than the speed of the airflow flowing through the third through hole 114 outside the protective cover 106, and at least part of the debris located in the protective cover 106 can flow out from the third through hole 114 under the action of the negative pressure. This helps to realize the discharge of the debris which is not discharged from the second through hole 110 from the third through hole 114. Through the secondary negative pressure discharge treatment, the debris entering the protective cover 106 can be effectively discharged from the protective cover 106 again, and the ventilation effect of the protective cover 106 is ensured.

[0406] As shown in FIG. 30 and FIG. 31, in an embodiment, the angle α3 between the third inclined surface 111 and the horizontal direction is 10°-45°, and the angle α3 between the third inclined surface 111 and the horizontal direction is preferably 10°, 13.65° and 45°. Due to the inclined structure design of the protective cover 106, the airflow at the first through hole 108 is accelerated during the flowing process to the second through hole 110, and the accelerated airflow is accelerated again during the flowing process to the third through hole 114, so that the negative pressure effect generated at the third through hole 114 is better, and the debris is discharged more cleanly from the protective cover 106.

[0407] In an embodiment, as shown in FIG. 32, for simulating the air flow speed of 3.6 m / s, when the first inclined surface 107 is set to have an angle of 52° with the horizontal direction and the third inclined surface 111 is set to have an angle of 13.65° with the horizontal direction, when the air is blown from the front to the back in the outdoor working environment, the air flow speed near the first through hole 108, the second through hole 110 and the third through hole 114 is shown in the figure, when the air flow speed is 3.6 m / s, the air flow speed near the first through hole 108 is 3.26 m / s, the air flow speed near the second through hole 110 is 5.15 m / s, and the air flow speed near the third through hole 114 is 5.94 m / s on the outside of the bottom of the protective cover 106. Obviously, when the air flow speed is 3.6 m / s, the air flow speed near the third through hole 114 is greater than the air flow speed near the second through hole 110, and the air flow speed near the second through hole 110 is greater than the air flow speed near the first through hole 108. By Bernoulli effect (Bernoulli effect refers to that in a fluid, if the speed is small, the pressure is large; if the speed is large, the pressure is small. Bernoulli effect is applicable to all ideal fluids including liquid and gas, and is one of the basic phenomena of stable fluid flow, reflecting the relationship between the pressure and the flow rate of the fluid. Specifically, the greater the flow rate of the fluid, the smaller the pressure; the smaller the flow rate of the fluid, the greater the pressure.), therefore, the air flow speed outside the protective cover 106 is greater than the air flow speed inside the protective cover 106 at the second through hole 110 and the third through hole 114, so that a pressure is generated outside the protective cover 106 at the second through hole 110 and the third through hole 114, and when the air flows, a negative pressure is generated to discharge the debris in the protective cover 106 through the second through hole 110 and the third through hole 114.

[0408] As shown in FIG. 30 and FIG. 31, in an embodiment, the heights of the first through hole 108, the second through hole 110 and the third through hole 114 on the protective cover 106 are sequentially decreased. Specifically, the bottom surface of the protective cover 106 is set as an inclined surface on the frame 100, and the heights of the first through hole 108, the second through hole 110 and the third through hole 114 on the protective cover 106 are sequentially decreased, and the flow rates of the air flowing through the first through hole 108, the second through hole 110 and the third through hole 114 are sequentially increased, which makes the negative pressure generated at the second through hole 110 and the third through hole 114 greater than that at the first through hole 108, and further helps to discharge the debris entering the protective cover 106 through the first through hole 108 through the second through hole 110 and the third through hole 114, reduces the accumulation of debris in the protective cover 106, and helps to dissipate heat of the power management device 219 in the protective cover 106.

[0409] As shown in FIG. 30 and FIG. 31, in an embodiment, in the up-down direction, the height of the lowest end of the first through hole 108, the height of the lowest end of the second through hole 110 and the height of the lowest end of the third through hole 114 are sequentially decreased. In the case that the weight of the debris is large and the effect of the discharge of the debris by the negative pressure is limited, in order to facilitate the discharge of the debris and the like, the height of the lowest end of the first through hole 108, the second through hole 110 and the third through hole 114 are sequentially decreased, which can facilitate the discharge of the debris and the like by the vibration effect when the external working equipment is running. In order to discharge the debris with large volume, in an embodiment of the present application, the hole area of the second through hole 110 and the third through hole 114 is designed to be large, so that the height of the upper end of the second through hole 110 and the third through hole 114 is higher than the height of the first through hole 108.

[0410] As shown in FIG. 31, in an embodiment, the third through hole 114 is designed as a long strip structure.

[0411] As shown in FIG. 31, in an embodiment, the protective cover 106 is provided with a recess 112 near the lower end of the third inclined surface 111, and the third through hole 114 is formed on one side surface of the recess 112. Specifically, the recess 112 is recessed inward from the outside of the protective cover 106, and the recess 112 formed by recessing is composed of a bottom surface and a plurality of side surfaces, and the third through hole 114 is formed on one of the side surfaces. In this way, it can prevent liquid from directly splashing onto the power management device 219 through the third through hole 114, and it can also prevent other hard objects and impurities from directly impacting onto the power management device 219, so as to prevent damage to the power management device 219.

[0412] In an embodiment, in order to improve the heat dissipation effect, the recess 112 is provided with a plurality of third through holes 114, and each recess 112 is provided with a third through hole 114. The plurality of third through holes 114 also increases the success rate of debris discharge. In addition, the orientations of the third through holes 114 on at least part of the recesses 112 are different. Specifically, the recesses 112 are arranged on the outside of the rear part of the power management device 219, and the orientations of the third through holes 114 are set to face away from or be away from the power management device 219, so as to guide the liquid or hard objects entering the third through hole 114 to not directly splash or impact onto the power management device 219, so as to prevent damage.

[0413] As shown in FIG. 23 and FIG. 28-31, in an embodiment, the frame 100 is provided with a power supply fixing member 116, and the power supply device 200 comprises a battery compartment 201 for mounting a battery pack, the battery compartment 201 is fixed above the power supply fixing member 116, and a power supply management fixing frame 105 is arranged below the power supply fixing member 116, and the power supply management device 219 is arranged on the power supply management fixing frame 105, and the power supply management device 219 is fixed below the battery pack through the power supply management fixing frame 105 and kept a certain distance from the battery pack, which is beneficial to the heat dissipation of the battery pack and the power supply management device 219 respectively and does not affect each other.

[0414] As shown in FIG. 23 and FIG. 24, in a specific embodiment, the power supply management fixing frame 105 comprises a fixing leg 1051 and a fixing plate 1052 connected with each other, the fixing leg 1051 is used for fixing with the power supply fixing member 116, and the fixing plate 1052 is used for mounting the power supply management device 219, and the fixing plate 1052 is provided with air holes 1053 for ventilation, which is beneficial to the flow of air and helps the heat dissipation of the upper surface of the power supply management device 219. The front part of the fixing plate 1052 is provided with a front baffle 1054, which extends downward and can protect the power supply management device 219. The front baffle 1054 is also provided with a baffle opening 1055 corresponding to the power supply management device 219, and when the outdoor working equipment moves forward, the air flow can enter the baffle opening 1055, so that the flowing air is formed below the power supply management fixing frame 105, which is beneficial to the heat dissipation of the power supply management device 219.

[0415] As shown in FIG. 5-8, FIG. 23 and FIG. 25-26, in an embodiment, in order to optimize the structure layout, the battery compartment 201 of the present application comprises two side plates 216 arranged correspondingly, and the two side plates 216 are respectively provided with electric connection terminals 220 connected with the battery pack, and the power supply management device 219 is located below the battery compartment 201, and in the front-rear direction of the outdoor working equipment, the power supply management device 219 is located between the two side plates 216, which makes the power supply management device 219 be able to directly connect with the electric connection terminals 220 on the two side plates 216 through the wire harness respectively. By mounting the power supply management device 219 between the two side plates 216 respectively provided with the electric connection terminals 220, the power supply management device 219 can be connected with the electric connection terminals 220 through shorter wire harness, which saves the wire harness and the space reserved for wiring.

[0416] Referring to FIGS. 5-8 and 23, in an embodiment, the two side plates 216 of the battery compartment 201 arranged along the front-rear direction of the outdoor working equipment are each provided with three electrical connection terminals 220, and correspondingly, the front part of the power management device 219 is provided with an interface 217 connected with the electrical connection terminals 220 of the front part of the battery compartment 201, and the rear part of the power management device 219 is provided with an interface 217 connected with the electrical connection terminals 220 of the rear part of the battery compartment 201, so that the connection line bundle space layout of the electrical connection terminals 220 connected with the power management device 219 is more reasonable, and the battery pack can be electrically connected with the power management device 219 through the electrical connection terminals 220.

[0417] Referring to FIGS. 5-8, in an embodiment, the lower part of each electrical connection terminal 220 is provided with an airflow generator 2031 (cooling fan), and the airflow generator 2031 is also connected with the power management device 219 downwardly through a line bundle, which saves the use of the line bundle, saves the raw material cost, and makes the overall layout of the outdoor working equipment more reasonable.

[0418] Referring to FIG. 28, in an embodiment, the interface 217 of the front part of the power management device 219 is connected with the vehicle control module, the airflow generator 2031 and the electrical connection terminal 220 through a cable 222, and the position of the cable 222 is higher than the interface 217 of the front part of the power management device 219, the height of the interface 217 of the front part of the power management device 219 is higher than the lowest end of the front apron 1054, and the cable 222 passes through the lowest end of the front apron 1054 to be connected with the interface 217 of the front part of the power management device 219, so that the lowest end of the cable 222 is below the lowest end of the front apron 1054. Since the height of the cable 222 connected with the vehicle control module, the airflow generator 2031 and the electrical connection terminal 220 is higher than the height of the interface 217 of the front part of the power management device 219, when there is liquid on the cable 222, the liquid will not flow into the power management device 219 along the cable 222, preventing the power management device 219 from being damp, thus the power management device 219 is well protected.

[0419] As shown in FIGS. 5-8 and 23, further, the battery compartment 201 includes two side plates 216 arranged correspondingly, and the two side plates 216 are respectively provided with cooling fans for cooling the battery pack, and in the horizontal direction, the power management device 219 is located between the two side plates 216 and can be electrically connected with the cooling fans on the two side plates 216 through a line bundle. Such arrangement also reasonably saves the line bundle distance of the power management device 219 connected with the cooling fans.

[0420] As shown in FIG. 1, FIG. 23, FIG. 28 and FIG. 31, in an embodiment, the lower surface of the power management device 219 is obliquely arranged towards the advancing direction of the outdoor working equipment. Such arrangement can increase the contact area between the lower surface of the power management device 219 and the airflow entering through the first through hole 108, and improve the heat dissipation effect of the power management device 219.

[0421] Further, the protective cover 106 is fixed to the frame 100 and detachably connected to the frame 100 by locking screws, which is convenient for disassembly and assembly.

[0422] As shown in FIG. 1, FIG. 22 and FIG. 28, in an embodiment, the outdoor working equipment of the present application comprises a frame 100; a power supply device 200 arranged on the frame 100 and used for at least powering the outdoor working equipment; a power management device 219 fixed below the frame 100 and used for controlling the charging or discharging of the power supply device 200; and a protective cover 106 arranged below the power management device 219; wherein the bottom of the power supply device 200, the frame 100 and the protective cover 106 form a protective space surrounding the power management device 219, so as to protect the power management device 219 from damage caused by external liquid or solid.

[0423] As shown in FIG. 31, the bottom of the protective cover 106 protrudes inwardly and is provided with two connected protruding portions 113.
