Description

Technical Field

[0001] The present application relates to the technical field of outdoor equipment, and particularly relates to an outdoor working equipment. Background Art

[0002] Outdoor working equipment, especially new energy lawn mowers, are widely used as a kind of lawn machinery in fields such as lawn trimming and vegetation.

[0003] Since the battery cells of the new energy battery pack generate heat during the charging and discharging processes, and due to the barrier of the battery pack housing, the heat dissipation effect inside the battery pack is limited, which will cause the temperature inside the battery pack to continuously rise, and may then lead to the battery pack expanding, leaking liquid or even exploding due to overheating, posing a safety hazard; also, due to the complex and diverse working climate environments of new energy lawn mowers, when operating in a relatively cold environment, if the temperature is low, it will affect the discharge effect of the battery pack and the endurance ability of the entire lawn mower. Therefore, it is necessary to cool the battery pack when its internal temperature is high and heat it when its internal temperature is low.

[0004] Moreover, in order to improve the adaptability of the lawn mower to different types of battery packs, some lawn mowers are designed to be able to accommodate the assembly of battery packs with different sizes or different capacitances. Since energy needs to be obtained from the battery pack when cooling and heating the battery pack, and different types of battery packs require different heat dissipation or cooling treatments, if not properly handled, it will cause unreasonable utilization of the battery pack's power and affect the endurance ability of the battery pack.

[0005] In view of this, it is indeed necessary to provide an improved outdoor working equipment to overcome the defects of the prior art. Summary of the Utility Model

[Detailed implementation manners]

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0056] Please refer to Figures 1 to 31 An outdoor working device according to an embodiment disclosed in this application is shown. Specifically, the outdoor working device includes a vehicle frame 100, a power supply device 200, an operation assembly 300, a seat 400, a power output assembly 500, and a traveling assembly 600.

[0057] The vehicle frame 100 extends in a direction. The power supply device 200 is arranged at the rear of the vehicle frame 100. The power supply device 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 installing the battery pack. The battery pack is electrically connected to the electrical connection terminal 220 on the battery compartment 201 through the power connection terminal thereon to supply power to the outdoor working device. The battery pack includes a first type of battery pack 205 and a second type of battery pack 206. Preferably, the battery compartment 201 can be arranged to accommodate the first type of battery pack 205 and the second type of battery pack 206 with different capacitances or different sizes to increase the adaptability of the outdoor working device to different battery packs. Among them, the battery pack can also be removed to supply power to other electric tools, increasing the multi-purpose nature of the battery pack. Compared with the traditional use of fossil fuels as the energy source, the outdoor working device of this application is more environmentally friendly and more in line with the long-term development plan. Preferably, the battery pack is preferably a lithium iron phosphate battery pack or a ternary lithium battery pack.

[0058] 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.

[0059] The operation assembly 300 includes a left operation lever and a right operation lever arranged on the left and right sides of the outdoor working device. The user controls the left operation lever and the right operation lever to control the outdoor working device to move forward, backward, or turn. The operation assembly 300 can also be a steering wheel capable of controlling the outdoor working device.

[0060] In one embodiment, control buttons for adjusting the operating speeds of the power output assembly 500 and the traveling assembly 600 are arranged on the operation assembly 300 to facilitate the user to quickly and accurately control the operation of the outdoor working device. Further, buttons for adjusting the brightness of the vehicle lights of the outdoor working device can also be arranged on the operation assembly 300.

[0061] The seat 400 is arranged on the vehicle frame 100, and the left operating lever and the right operating lever are arranged close to the seat 400 and located on the left and right sides of the seat 400, so that a user sitting on the seat 400 can operate the left operating lever and the right operating lever to control the operation of the outdoor working equipment.

[0062] The power output component 500 is a workpiece for realizing the tool function. In one embodiment, the outdoor working equipment is a riding mower, and the power output component 500 is specifically a cutting component, which is arranged below the vehicle frame 100 and is used to output power to realize the mowing function of the riding mower. The cutting component is arranged in 2 groups or 3 groups.

[0063] In one embodiment, the cutting component includes: a cutter head, a mowing element and a cutting motor. The cutting motor is controlled by a control button on the operation component 300, and the mowing element is used to cut vegetation such as grass when rotating at a high speed. For example, the mowing element is a blade for cutting the vegetation on the lawn. The cutter head forms a mowing space for accommodating the mowing element, and the mowing element is at least partially located in the mowing space. In some embodiments, the number of mowing elements can be 2, and correspondingly, the number of cutting motors is also 2. The two cutting motors independently drive the two mowing elements respectively. In some embodiments, the number of mowing elements can be 3, and correspondingly, the number of cutting motors is also 3. The three cutting motors independently drive the three mowing elements respectively.

[0064] Of course, the power output component 500 can also be detached from the outdoor working equipment. In some embodiments, it can be understood that the power output component 500 can be replaced with other components to meet the usage requirements of different garden operations. Therefore, the outdoor garden mower can not only cut vegetation, but also replace the cutting component with functional components such as snow shoveling, snow sweeping, snow blowing, and flushing. Those skilled in the art should be able to adaptively replace various functional components without creative labor, and the above should all be included in the protection scope of this embodiment.

[0065] When the cutting component is replaced with functional components such as snow shoveling, snow sweeping, and snow blowing, the power supply device 200 of the outdoor working equipment of the present application can also adapt to a relatively cold environment to supply power to the above-mentioned functional components such as snow shoveling, snow sweeping, and snow blowing.

[0066] The traveling component 600 includes traveling wheels arranged on the vehicle frame 100 and a traveling motor for driving the traveling wheels. The traveling wheels are arranged on both sides of the vehicle frame 100, so that the center of gravity of the outdoor working equipment is kept within the vehicle frame 100 to reduce the probability of the outdoor working equipment tipping over during traveling.

[0067] In one embodiment, the number of running wheels is set to 4, including 2 front running wheels 601 and 2 rear running wheels 602. The front running wheel 601 can be a universal wheel, and the running motor is connected to the rear running wheel 602 and drives the rear running wheel 602 to rotate. The two rear running wheels 602 are matched with the running motor, and the speeds of the two running motors can be the same or different. When the user drives the outdoor working equipment straight, the speeds of the two running motors are roughly the same; when the user drives the outdoor working equipment to turn, the speeds of the two running motors are different, and the outdoor working equipment turns to the side with the lower speed of the running motor. In some embodiments, the diameter of the front running wheel 601 is smaller than the diameter of the rear running wheel 602.

[0068] In one embodiment, please also refer to Figure 2 , Figure 3 and Figure 4 The power supply device 200 is used at least to supply power to outdoor working equipment. The power supply device 200 includes a battery compartment 201. A first type battery pack 205 or a second type battery pack 206 can be installed in the battery compartment 201, or both the first type battery pack 205 and the second type battery pack 206 can be installed simultaneously. The first type battery pack 205 and the second type battery pack 206 can be installed in the battery compartment 201 in a detachable manner.

[0069] The first type battery pack 205 and the second type battery pack 206 can also be removed from the battery compartment 201 to power other tools.

[0070] See also Figure 2 , Figure 3 and Figure 4 A plurality of temperature control components 203 are also provided on the battery compartment 201. The plurality of temperature control components 203 perform temperature control operations by obtaining electrical energy from the battery packs on the outdoor working equipment. The plurality of temperature control components 203 are configured to be able to control the temperature of the first type battery pack 205 and / or the second type battery pack 206.

[0071] Of course, the energy of the multiple temperature control components 203 can be obtained by the first type battery pack 205 or the second type battery pack 206 in the battery compartment 201, or other battery packs that can supply energy on the outdoor working equipment.

[0072] See also Figure 2 , Figure 3 and Figure 4 Specifically, when the first type battery pack 205 and the second type battery pack 206 need to be cooled, the temperature control component 203 is an airflow generator 2031 capable of generating airflow, which can be a cooling fan, for cooling the first type battery pack 205 and the second type battery pack 206.

[0073] When the first - type battery pack 205 and the second - type battery pack 206 need to be heated, the temperature - regulating component 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 towards the first - type battery pack 205 and the second - type battery pack 206 for heating treatment.

[0074] For example Figure 2 , in an embodiment, when the number of the first - type battery packs 205 loaded in the battery compartment 201 is x, the number of the temperature - regulating components 203 configured to be able to regulate the temperature of the first - type battery packs 205 is x. Specifically, the number of the temperature - regulating components 203 configured to regulate the temperature of x first - type battery packs 205 at any time is x.

[0075] In an embodiment, when the internal temperatures of m first - type battery packs 205 among the x first - type battery packs 205 are higher than the normal range value and within the first range value, the power management device 219 will start m temperature - regulating components 203 to regulate the temperature of the m first - type battery packs 205 with internal temperatures within the first range value until the temperature is regulated to the normal range value.

[0076] In this way, setting the number of the first - type battery packs 205 and the number of the temperature - regulating components 203 in a one - to - one matching manner is to meet the requirement that although the temperature of the first - type battery pack 205 during charging and discharging is different from the temperature of the normal range value, in the case of limited temperature - regulation requirements, one temperature - regulating component 203 can meet the heat - dissipation or heating requirements of one first - type battery pack 205, and the first - type battery packs 205 with temperatures within the normal range value do not undergo temperature - regulation treatment. Since the energy source of the temperature - regulating component 203 also comes from the battery pack, it can save the electric energy of the battery pack and improve the battery - pack's endurance.

[0077] Furthermore, 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 - regulating component 203 only starts the air - flow generator 2031 to dissipate heat from the first - type battery pack 205, so that the temperature inside the first - type battery pack 205 can quickly drop to within the normal range value, which is helpful for the 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 - regulating component 203 starts the air - flow generator 2031 and the heater. The air - flow generator 2031 blows the heat generated by the heater towards the first - type battery pack 205 to heat the first - type battery pack 205, so as to raise the temperature inside the first - type battery pack 205 to the normal range value, which is helpful for the charging or discharging of the battery pack.

[0078] 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 outlet of the air flow generator 2031.

[0079] In one embodiment, when the one-to-one heat dissipation method cannot meet the temperature regulation requirements of the first type of battery pack 205, that is, when the number of the first type of battery packs 205 with the internal temperature in the second range value is m, the number of the temperature regulation components 203 configured to regulate the temperature of m first type of battery packs 205 is at least m + 1 and at most all the temperature regulation components 203 on the outdoor operation device. Specifically, the power management device 219 will allocate the work of the temperature regulation components 203 according to the temperature conditions inside the first type of battery pack 205. When the temperature inside the first type of battery pack 205 is in the second range value, the power management device 219 will start multiple temperature regulation components 203 simultaneously to regulate the temperature of the first type of battery pack 205, so as to ensure the normal charge and discharge requirements of the first type of battery pack 205.

[0080] It should be understood that when the temperature inside the first type of battery pack 205 or the second type of battery pack 206 is in the first range value and higher than the normal range value, and the second range value is higher than the first range value, heat dissipation treatment needs to be carried out on the first type of battery pack 205 or the second type of battery pack 206; when the temperature inside the first type of battery pack 205 or the second type of battery pack 206 is in the first range value and lower than the normal range value, and the second range value is lower than the first range value, heating treatment needs to be carried out on the first type of battery pack 205 or the second type of battery pack 206.

[0081] In a preferred embodiment, the capacitance of the first type of battery pack 205 is greater than or equal to 90 Wh and less than 1000 Wh, and the capacitance of the first type of battery pack 205 is preferably 90 Wh, 600 Wh or 999 Wh.

[0082] Such as Figure 3 , in one embodiment, when the number of the second type of battery packs 206 loaded into the battery compartment 201 is y, the number of the temperature regulation components 203 configured to be able to regulate the temperature of the second type of battery packs 206 is 2y. Setting the number of the second type of battery packs 206 and the number of the temperature regulation components 203 in a one-to-two matching manner is set in the case where one temperature regulation component 203 cannot meet the heat dissipation or heating requirements of one second type of battery pack 206.

[0083] In a specific embodiment, the capacitance of the second type of battery pack 206 is relatively large. The capacitance of the second type of battery pack 206 is generally greater than or equal to 1000 Wh and less than or equal to 4000 Wh, and the capacitance of the second type of battery pack 206 is preferably 1000 Wh, 2500 Wh and 4000 Wh.

[0084] In one embodiment, when the number of the internal temperatures of y second-type battery packs 206 installed in the battery compartment 201 within the first range value is n, the power management device 219 activates 2n temperature control components 203 to perform temperature control processing on n second-type battery packs 206 whose internal temperatures are within the first range value.

[0085] In this way, the number of the second-type battery packs 206 and the number of the temperature control components 203 are set in a one-to-two matching manner. This is to meet the heat generation during charging and discharging of the second-type battery packs 206 when one temperature control component 203 cannot meet the requirement. In this case, two temperature control components 203 are needed to meet the heat dissipation or temperature increase requirements of one second-type battery pack 206. And for the second-type battery packs 206 with temperatures within the normal range value, no temperature control processing is performed. Since the energy source of the temperature control components 203 also comes from the battery packs, under the condition of meeting the temperature control requirements, the fewer the number of activated temperature control components 203, the more electric energy of the battery packs can be saved, and the battery life of the battery packs can be improved.

[0086] In one embodiment, when the number of the internal temperatures of y second-type battery packs 206 installed in the battery compartment 201 within the second range value is n, the power management device 219 activates at least 2n + 1 temperature control components 203 to perform temperature control processing on n second-type battery packs 206 whose internal temperatures are within the second range value, and at most all the temperature control components 203 on the outdoor working device perform temperature control processing on n second-type battery packs 206 whose internal temperatures are within the second range value.

[0087] Such as Figures 2 to 13 and Figure 18 , in one embodiment, the battery compartment 201 includes two side plates 216 arranged oppositely. A temperature control component 203 is provided on each side plate 216, and the temperature control components 203 on one side plate 216 are arranged in one-to-one correspondence with the temperature control components 203 on the other side plate 216.

When the second-type battery pack 206 is installed in the battery compartment 201, one of the two power connection terminals 2061 is connected to one electric connection terminal 220 on one side plate 216, and the other of the two power connection terminals 2061 is connected to the electric connection terminal 220 on the other side plate 216. The first-type battery pack 205 supplies power to the outdoor working device through one power connection terminal 2051, and the second-type battery pack 206 supplies power to the outdoor working device through two power connection terminals 2061.

[0088] As Figure 5 and Figure 18 shown, in one embodiment, the battery compartment 201 includes two side plates 216 disposed opposite to each other, and a plurality of mounting positions 224 are provided on each side plate 216. The mounting positions 224 on one side plate 216 are arranged in one-to-one correspondence with the mounting positions 224 on the other side plate 216. Two mounting positions 224 arranged in one-to-one correspondence form a pair. At least one pair of mounting positions 224 is arranged offset from other mounting positions 224. The offset arrangement of the mounting positions 224 helps to enhance the structural strength of the battery compartment 201.

[0090] Furthermore, electrical connection terminals 220 are provided on each mounting position, so that at least one pair of electrical connection terminals 220 is arranged offset from other electrical connection terminals 220.

[0091] As Figure 5 and Figure 18 , in a specific embodiment, three air flow exchange parts 204 are respectively provided on two corresponding side plates 216 of the battery compartment 201. One side plate 216 is provided with three air flow exchange parts 204, and a total of six air flow exchange parts 204 are provided on two side plates 216. A temperature control component 203 is provided corresponding to each air flow exchange part 204. Therefore, six temperature control components 203 are also provided. Correspondingly, six electrical connection terminals 220 are also provided on two side plates 216 of the battery compartment 201. Three electrical connection terminals 220 are provided on one side plate 216, and three electrical connection terminals 220 are also provided on the other side plate 216, and each electrical connection terminal 220 is provided in the upper region of the air flow exchange part 204.

[0092] In one embodiment, the air flow exchange part 204 is provided on the mounting position 224.

[0093] As Figures 2 to 4 , the battery compartment 201 has an open hatch, and this hatch is used for loading and unloading the first type of battery pack 205 and the second type of battery pack 206. A hatch cover 202 is provided corresponding to this hatch. The hatch cover 202 is used to cover the hatch of the battery compartment 201, so that the battery compartment 201 forms a relatively closed cavity to reduce sundries from entering the battery compartment 201 and ensure the normal operation of the first type of battery pack 205 or the second type of battery pack 206.

[0094] As Figures 5 to 8As shown, a plurality of air flow exchange parts 204 are provided on two corresponding side plates 216 of the battery compartment 201, and one temperature control component 203 corresponds to one air flow exchange part 204. The temperature control component 203 can exhaust air and intake air into the battery compartment 201 through the corresponding air flow exchange part 204.

[0095] As Figures 5 to 8 shown, in an embodiment, when the internal temperature of the first type of battery pack 205 is within the first range value, the temperature control component 203 can blow air to the first type of battery pack 205 installed in the battery compartment 201 through the air flow exchange part 204, or exhaust air to the outside through the air flow exchange part 204 corresponding to the first type of battery pack 205.

The plurality of temperature control components 203 can blow air into the battery compartment 201 simultaneously; they can also exhaust air to the outside of the battery compartment 201 simultaneously; or some can blow air into the battery compartment 201 and some can exhaust air to the outside of the battery compartment 201.

[0097] As Figure 3 and Figures 5 to 8 In an embodiment, when the internal temperature of the second type of battery pack 206 is within the first range value, two temperature control components 203 can blow air to the second type of battery pack 206 installed in the battery compartment 201 simultaneously through the air flow exchange part 204, or exhaust air simultaneously, or one blows air and the other exhausts air. Preferably, the two temperature control components 203 are respectively provided on two corresponding side plates 216 of the battery compartment 201. The power connection terminals 2061 at both ends of the second type of battery pack 206 are respectively connected to two electrical connection terminals 220 located on the battery compartment 201 corresponding thereto, and the two temperature control components 203 are near the electrical connection terminals 220 on the two side plates 216. Therefore, the temperature control components 203 can also dissipate the heat generated by the contact between the electrical connection terminals 220 and the power connection terminals 2061.

[0098] Further, when the internal temperature of the second type of battery pack 206 is within the second range value, a plurality of temperature control components 203 can blow air to the second type of battery pack 206 installed in the battery compartment 201 simultaneously through the air flow exchange part 204, or exhaust air simultaneously, or at least one blows air and at least one exhausts air.

[0099] Please also refer to Figures 5 to 8 、 Figure 10 and Figure 11, in order to improve the heat dissipation or temperature increase effect, in one embodiment, a first vent 2052 and a second vent 2053 are provided on the first type of battery pack 205, and one of the first vent 2052 and the second vent 2053 corresponds to the air outlet direction of the air flow generator 2031. With such a setting, when the temperature adjustment component 203 performs temperature adjustment on the first type of battery pack 205 or the second type of battery pack 206, the heat in the first type of battery pack 205 can be taken away through the first vent 2052 or the second vent 2053, so that the inside of the first type of battery pack 205 can be quickly cooled to reach the normal range value, or the first type of battery pack 205 can be heated through the first vent 2052 or the second vent 2053, so that the temperature in the first type of battery pack 205 can quickly rise, so that the temperature in the first type of battery pack 205 reaches the normal range value.

[0100] Please refer to Figures 5 to 8 , Figure 12 and Figure 13 , in one embodiment, a third vent 2062 and a fourth vent 2603 are provided on the second type of battery pack 206. Preferably, the third vent 2062 and the fourth vent 2603 are provided at both ends of the second type of battery pack 206 having the power connection terminal 2061 and are located below the power connection terminal 2061 of the second type of battery pack 206. The third vent 2062 and the fourth vent 2603 respectively correspond to the air flow exchange part 204 provided on two corresponding side plates 216 of the battery compartment 201, which is beneficial for the temperature adjustment component 203 to take away the heat inside the second type of battery pack 206 through the air flow exchange part 204, or to quickly increase the temperature inside the second type of battery pack 206 through the air flow exchange part 204, so that the second type of battery pack 206 can quickly return to the normal temperature range value.

[0101] In one embodiment, when the second type of battery pack 206 needs to be cooled, the power management device 219 can control the operation of the air flow generator 2031 in the temperature adjustment component 203, and the heater does not operate. Blow air into the second type of battery pack 206 through one of the third vent 2062 and the fourth vent 2603, and discharge the hot air in the second type of battery pack 206 through the other of the third vent 2062 and the fourth vent 2603. In this way, the heat in the second type of battery pack 206 can be taken away by means of heat exchange with the outside, so that the second type of battery pack 206 can be quickly cooled to the normal range value.

[0102] In one embodiment, when the second type of battery pack 206 needs to be heated, the power management device 219 can control the air flow generator 2031 and the heater in the temperature control component 203 to operate simultaneously, blowing air simultaneously at the third vent 2062 and the fourth vent 2603 of the second type of battery pack 206. At the same time, exhaust holes 2064 are provided on the housing of the second type of battery pack 206, which can exhaust the cold air inside the second type of battery pack 206, so that the temperature inside the second type of battery pack 206 can be quickly raised to the normal range value. In a specific embodiment, the exhaust holes 2064 are provided on both sides of the power connection terminals on the battery pack.

[0104] Specifically, the power supply unit includes the first type of battery pack 205 or the second type of battery pack 206 or a combination of the first type of battery pack 205 and the second type of battery pack 206. Temperature detection modules are provided inside both the first type of battery pack 205 and the second type of battery pack 206 for detecting the temperatures inside the first type of battery pack 205 and the second type of battery pack 206. The power management module is the above-mentioned power management device 219, and the power management device 219 is electrically connected to the temperature detection module. When the temperature inside the first type of battery pack 205 or the second type of battery pack 206 detected by the temperature detection module is within the first range value, the power management module controls the temperature control component 203 to heat or cool the temperature inside the first type of battery pack 205 or the second type of battery pack 206; when the temperature inside the first type of battery pack 205 or the second type of battery pack 206 detected by the temperature detection module is within the second range value, the power management module controls the plurality of temperature control components 203 to continue heating or cooling the first type of battery pack 205 or the second type of battery pack 206. At this time, the first type of battery pack 205 or the second type of battery pack 206 is charged or discharged with a low current until the charge and discharge are completed.

[0105] The temperature adjustment component 203 includes an air flow generator 2031 capable of generating an air flow. When the first range value is higher than the temperature at which the power supply unit operates normally, the air flow generator 2031 is used to dissipate heat from the power supply unit. When the second range value is greater than the first range value, the air flow generator 2031 continues to be used to dissipate heat from the power supply unit.

[0106] The temperature adjustment component 203 includes an air flow generator 2031 capable of generating an air flow and a heater capable of generating heat. When the first range value is lower than the temperature at which the power supply unit operates normally, the air flow generator 2031 is used to blow the heat generated by the heater towards the corresponding power supply unit for heating.

[0107] When the second range value is less than the first range value, the air flow generator 2031 is used to blow the heat generated by the heater towards the corresponding power supply unit for heating.

[0108] Such as Figure 2 In an embodiment, the power supply unit includes a first type of battery pack 205. When the number of first type of battery packs 205 with an internal temperature within the first range value is m, the number of temperature adjustment components 203 configured to adjust the temperature of m first type of battery packs 205 is m. Specifically, when the number of first type of battery packs 205 with an internal temperature within the first range value is 1, the number of temperature adjustment components 203 configured to adjust the temperature of 1 first type of battery pack 205 is 1.

[0109] In an embodiment, the power supply unit includes a first type of battery pack 205. When the number of first type of battery packs 205 with an internal temperature within the second range value is m, the number of temperature adjustment components 203 configured to adjust the temperature of m first type of battery packs 205 is at least m + 1 and at most all the temperature adjustment components 203 on the outdoor working device.

[0110] When the number of first type of battery packs 205 with an internal temperature within the second range value is 1, the number of temperature adjustment components 203 configured to adjust the temperature of 1 first type of battery pack 205 is at least 2 and at most all the temperature adjustment components 203 on the outdoor working device. In an embodiment, there are 6 temperature adjustment components 203, and 2, 3, or 5 temperature adjustment components 203 can work, but at most 6 temperature adjustment components 203 simultaneously perform heat dissipation or temperature increase processing for 1 first type of battery pack 205.

[0111] It should be understood that when the number of first type of battery packs 205 loaded into the battery compartment 201 is 6, at most 6 temperature adjustment components 203 dissipate heat from the first type of battery pack 205.

[0112] Such as Figure 3As shown, in one embodiment, the power supply unit includes a second type of battery pack 206. When the number of second type of battery packs 206 with internal temperature within the first range value is n, the number of temperature control components 203 configured to control the temperature of n second type of battery packs 206 is 2n. When the number of second type of battery packs 206 with internal temperature within the first range value is 1, the number of temperature control components 203 configured to control the temperature of 1 second type of battery pack 206 is 2.

[0113] In one embodiment, the power supply unit includes a second type of battery pack 206. When the number of second type of battery packs 206 with internal temperature within the second range value is n, the number of temperature control components 203 configured to control the temperature of n second type of battery packs 206 is at least 2n + 1 and at most all the temperature control components 203 on the outdoor working device. When the number of second type of battery packs 206 with internal temperature within the second range value is 1, the number of temperature control components 203 configured to control the temperature of 1 second type of battery pack 206 is at least 3 and at most all the temperature control components 203 on the outdoor working device. In one embodiment, there are 6 temperature control components 203, and at most 6 temperature control components 203 simultaneously perform heat dissipation or heating treatment for 1 second type of battery pack 206. Of course, the temperature control components 203 can also be set to 8, 9, 10, or even more according to requirements.

[0114] It should be understood that when the temperature inside the first type of battery pack 205 or the second type of battery pack 206 is raised or lowered to the normal range value, the temperature control component 203 stops operating to save the power consumption of the first type of battery pack 205 or the second type of battery pack 206. When the temperature inside the first type of battery pack 205 or the second type of battery pack 206 is not within the normal range value, the temperature control component 203 operates again to perform temperature adjustment on the first type of battery pack 205 or the second type of battery pack 206.

[0115] The first range value, the second range value, and the normal range value are not limited to a specific range value and are adjustable, and can be set according to different usage requirements.

[0116] Such as Figure 9 and Figure 19As shown, in one embodiment, an installation groove 207 is provided on the battery compartment 201 and around the air flow exchange part 204. The temperature regulation assembly 203 includes an installation bracket 2032, an air flow generator 2031 and a heater fixed on the installation bracket 2032. When the installation bracket 2032 is installed and fitted with the installation groove 207, the air flow exchange part 204 corresponds to the air outlet of the air flow generator 2031. With such a setting, the temperature regulation assembly 203 can be quickly disassembled and assembled on the battery compartment 201, so as to facilitate the replacement and maintenance of the temperature regulation assembly 203. Specifically, the air flow generator 2031 is fixed on the installation bracket 2032 by screws. The installation bracket 2032 is provided with guide rails 2033, and the guide rails 2033 cooperate with the installation groove 207 to realize the installation of the installation bracket 2032 outside the battery compartment 201, and further realize the installation of the air flow generator 2031 on the battery compartment 201.

[0117] In one embodiment, the bottom of the installation bracket 2032 is a fixing part 2034, and a fixing position 2035 is provided on the fixing part 2034. Fixing parts such as bolts can fix the fixing part 2034 to the battery compartment 201 through the fixing position 2035, so as to fix the installation bracket 2032 and the air flow generator on the installation bracket to the battery compartment 201. After the installation bracket 2032 is slid and fitted with the installation groove 207 in place, the installation bracket 2032 can be fixed to the battery compartment 201 by fixing parts such as screws.

[0118] As Figures 5 to 8 shown, in one embodiment, a drain hole 208 for draining water is further provided at the bottom of the battery compartment 201, so as to facilitate the drainage of accumulated water or waste liquid in the battery compartment 201, so as not to affect the normal use of the first type of battery pack 205 or the second type of battery pack 206.

[0119] As Figure 1 、 Figure 15 and Figure 16 , in one embodiment, the outdoor working device of the present application includes a vehicle frame 100, and the vehicle frame 100 is provided with: a seat 400 for a user to sit on; a traveling assembly 600 for supporting the outdoor working device to travel, and the traveling assembly 600 includes a front traveling wheel 601 and a rear traveling wheel 602; a power output assembly 500 for performing outdoor work; a power supply device 200 for supplying power to the outdoor working device; the vehicle frame 100 includes: a first load-bearing part 101 for at least bearing the seat 400; a second load-bearing part 103 for at least bearing the power supply device 200; wherein, the heights of the first load-bearing part 101 and the second load-bearing part 103 are different.

[0120] In one embodiment, the vehicle frame 100 is provided with a first load-bearing part 101 and a second load-bearing part 103 with different heights, so that the vehicle frame 100 can withstand greater impacts.

[0121] As Figure 1 and Figure 16 shown, in one embodiment, the front part of the frame 100 is a first load-bearing part 101 for carrying the seat 400 on which a user can sit, and the tail of the frame 100 is for carrying the power supply device 200. When the height of the second load-bearing part 103 is lower than that of the first load-bearing part 101, it is beneficial to lower the center of gravity of the entire outdoor working device, making the outdoor working device more stable during operation. In addition, when the upper height is limited, the tail of the frame 100 where the power supply device 200 is installed is designed to sink, so that the volume of the battery compartment 201 of the power supply device 200 can be made larger to a greater extent within the limited space, enabling the battery compartment 201 to accommodate a large-capacity battery pack with a larger volume, thereby improving the endurance of the outdoor working device.

[0122] As Figure 15 , in one embodiment, the height difference h between the first load-bearing part 101 and the second load-bearing part 103 is 100 mm to 150 mm, and the height difference h between the first load-bearing part 101 and the second load-bearing part 103 is preferably 100 mm, 125 mm, and 150 mm.

[0123] As Figure 16 , in one embodiment, a power supply fixing member 116 is provided on the frame 100, and the power supply fixing member 116 is obliquely connected to the connecting part 102 and the second load-bearing part 103. Specifically, since the height of the first load-bearing part 101 is higher than that of the second load-bearing part 103, at least part of the connecting part 102 connecting the two is higher than the second load-bearing part 103. Preferably, the overall height of the connecting part 102 is higher than that of the second load-bearing part 103. The power supply fixing member 116 is preferably a flat plate. One end of the power supply fixing member 116 is lapped on the connecting part 102, and the other end is lapped on the second load-bearing part 103, so that the bottom surface of the power supply fixing member 116 can be inclined towards the advancing direction of the outdoor working device. The bottom of the battery compartment 201 is a flat surface. When the battery compartment 201 is placed on the inclined power supply fixing member 116, the opening of the battery compartment 201 can be inclined towards the rear of the outdoor working device. In this way, when the user replaces the battery pack in the battery compartment 201, the inclined opening of the battery compartment 201 is beneficial for the user to take and place the battery pack. The battery pack in this embodiment includes the above-mentioned first type of battery pack 205 and second type of battery pack 206.

[0124] In one embodiment, the frame 100 is provided with a first load-bearing part 101 and a second load-bearing part 103 with different heights, so that the frame 100 can withstand greater impacts.

[0125] As Figure 1 and Figure 15As shown, in one embodiment, the height of the lower surface of the first bearing part 101 from the ground is 279 mm to 381 mm, and preferably 279 mm, 300 mm, and 381 mm. Further, the ratio of the height of the lower surface of the first bearing part 101 from the ground to the radius of the front traveling wheel 601 is 2 to 3 times, and preferably 2 times, 2.5 times, and 3 times.

[0126] In one embodiment, the height of the lower surface of the second bearing part 103 from the ground is 228 mm to 366 mm, and preferably 228 mm, 300 mm, and 366 mm. Further, the ratio of the height of the lower surface of the second bearing part 103 from the ground to the radius of the rear traveling wheel 602 is 1 to 1.2 times, and preferably 1 time, 1.1 times, and 1.2 times.

[0127] As Figure 1 , Figure 15 and Figure 16 , the second bearing part 103 is provided with a hitch 104 for towing outdoor working equipment. In the vertical direction, the distance between the hitch 104 and the axis of the rear traveling wheel 602 is 200 mm to 380 mm, and preferably 200 mm, 300 mm, and 380 mm. Such a design is to prevent the vehicle from tipping over during the towing process due to the hitch point being too high or too low.

[0128] As Figure 15 , in a preferred embodiment, the present application further includes a connecting part 102 connecting the first bearing part 101 and the second bearing part 103. The connecting part 102 is inclined. The angle α4 between the connecting part 102 and the first bearing part 101 is 10° to 30°, and preferably 10°, 20°, and 30°. The angle α5 between the connecting part 102 and the second bearing part 103 is 10° to 30°, and preferably 10°, 20°, and 30°.

[0129] Of course, when the first bearing part 101 and the second bearing part 103 are horizontally arranged, the connecting part 102 can be connected to the first bearing part 101 and the second bearing part 103 in a perpendicular relationship.

[0130] As Figure 15, in a preferred embodiment, along the extending direction of the vehicle frame 100, the ratio of the lengths of the first bearing portion 101, the connecting portion 102 and the second bearing portion 103 is L1:L2:L3 = 5 - 8:6 - 10:30 - 40. Preferably, the ratio of the lengths of the first bearing portion 101, the connecting portion 102 and the second bearing portion 103 is L1:L2:L3 = 5:6:30, L1:L2:L3 = 6:8:35 and L1:L2:L3 = 8:10:40.

[0131] In one embodiment, the first bearing portion 101, the second bearing portion 103 and the connecting portion 102 are of an integral structure. The integral vehicle frame 100 structure has better strength than the split vehicle frame 100 and saves the assembly time of the entire outdoor working equipment.

[0132] In one embodiment, the connecting portion 102 and the first bearing portion 101 are of an integral structure, and the connecting portion 102 and the second bearing portion 103 are of a split structure; in another embodiment, the connecting portion 102 and the first bearing portion 101 are of a split structure, and the connecting portion 102 and the second bearing portion 103 are of an integral structure; in another embodiment, the connecting portion 102, the first bearing portion 101 and the first bearing portion 101 are all of a split structure. Such a design is beneficial to disassembling the vehicle frame 100 for easy transportation.

[0133] In another embodiment, when the height of the second bearing portion 103 is higher than that of the first bearing portion 101, it is beneficial to increase the height of the tail of the vehicle frame 100. When the outdoor working equipment is in a rough area, especially on a road that requires repeated uphill and downhill driving, the higher setting of the tail height of the vehicle frame 100 increases the departure angle of the tail of the vehicle frame 100, which is beneficial to improving the passing ability of the outdoor working equipment.

[0134] As Figures 17 to 23 shown, in one embodiment, the outdoor working equipment of the present application includes a vehicle frame 100; a power supply device 200 is provided on the vehicle frame 100, which is at least used to supply power to the outdoor working equipment; a power management device 219 is arranged below the power supply device 200, and the power management device 219 is at least used to control the charging or discharging of the power supply device 200; a protective cover 106 is at least used to protect the power management device 219. The protective cover 106 is arranged below the power management device 219, and at least a first through hole 108 and a second through hole 110 for heat dissipation are provided on the protective cover 106. The power management device 219 is arranged below the power supply device 200, and a protective cover 106 for protecting the power management device 219 is provided to prevent damage to the power management device 219 caused by liquids, 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 provided on the protective cover 106 in the present application for heat dissipation of the power management device 219.

[0135] As Figure 1 , Figure 17 , Figure 18 and Figure 23 shown, the cutting assembly of the outdoor working device of the present application is arranged below the vehicle frame 100, and the power management device 219 is also arranged below the vehicle frame 100 and behind the cutting assembly. When the outdoor working device 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, accumulation will occur, affecting the heat dissipation effect of the power management device 219. 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 that is inclined along the forward direction of the outdoor working device. The first through hole 108 and the second through hole 110 are respectively arranged at the upper end and the lower end of the first inclined surface 107; when the outdoor working device moves forward, outside the protective cover 106, the flow rate of the air flow through the first through hole 108 is less than the flow rate through the second through hole 110. Among them, at least part of the debris entering the protective cover 106 through the first through hole 108 can flow out from the second through hole 110 under the action of negative pressure. In this way, both the ventilation effect of the protective cover 106 is ensured, and the Bernoulli principle can be used to effectively discharge the debris entering the protective cover 106 from the first through hole 108 out of the protective cover 106 through the second through hole 110 under the action of negative pressure.

[0136] As Figure 22 shown, in an embodiment, the included angle α1 between the first inclined surface 107 and the horizontal direction is 40° to 85°, and the included angle α1 between the first inclined surface 107 and the horizontal direction is preferably 40°, 52° and 85°. It should be understood that the larger the included angle between the first inclined surface 107 and the horizontal direction, the greater the flow rate difference between the first through hole 108 and the second through hole 110, so the greater the pressure difference generated, and the better the negative pressure effect at the second through hole 110, and the better the effect of discharging debris.

[0137] As Figure 23 , in an embodiment, the hole area of the first through hole 108 is 60mm 2 ~80mm 2 , and the hole area of the first through hole 108 is preferably 60mm 2 , 70mm 2 and 80mm 2 .

[0138] As Figure 23, the hole area of the second through hole 110 is 3 to 50 times that of the first through hole 108, and preferably 3 times, 30 times, and 50 times that of the first through hole 108. Designing the hole area of the first through hole 108 to be small can minimize the entry of debris into the protective cover 106 while ensuring ventilation and heat dissipation; while designing the second through hole 110 to be larger than the first through hole 108 helps to discharge the debris that has entered the protective cover 106 through the larger second through hole 110.

[0139] Such as Figure 22 And Figure 23 , in an embodiment, a groove 115 capable of collecting debris is formed on the protective cover 106, 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 to the first inclined surface 107. The lower end of the second inclined surface 109 is connected to the lower end of the first inclined surface 107, and the second through hole 110 is located at the connection of the first inclined surface 107 and the second inclined surface 109. The design of the second inclined surface 109 helps to block the debris that has entered the protective cover 106, so that the debris that enters the groove 115 can move as much as possible in the direction of the groove 115 and reduce the movement towards the rear of the protective cover 106.

[0140] Such as Figure 22 , in an embodiment, the angle α2 between the second inclined surface 109 and the horizontal direction is 0° to 60°, and preferably 0°, 30°, and 60°. The larger the angle α2 between the second inclined surface 109 and the horizontal direction, the better the blocking effect on the debris, so that the movement of the debris towards the rear of the protective cover 106 can be minimized.

[0141] Please refer to Figure 22 And Figure 23, in one embodiment, in order to discharge the debris that has not been discharged from the second through hole 110 and has moved to the rear of the protective cover 106, the rear of the protective cover 106 of the present application is also provided with a third inclined surface 111 that is connected to the second inclined surface 109 and is inclined along the forward direction of the outdoor working device. The upper end of the third inclined surface 111 is connected to the upper end of the second inclined surface 109. Specifically, a third through hole 114 is provided at the lower end of the protective cover 106 where the protective cover 106 is located; when the outdoor working device moves forward, outside the protective cover 106, the flow rate of the airflow passing through the second through hole 110 is less than the flow rate passing through the third through hole 114. Among them, at least part of the debris located inside the protective cover 106 can flow out from the third through hole 114 under the action of negative pressure. This helps to discharge the debris that has not been discharged from the second through hole 110 from the third through hole 114. In this way, through the secondary negative pressure chip removal treatment, the debris that has entered the protective cover 106 can be effectively discharged from the protective cover 106 again, and the ventilation effect of the protective cover 106 is also ensured.

[0142] As Figure 22 and Figure 23 , in one embodiment, the included angle α3 between the third inclined surface 111 and the horizontal direction is 10° to 45°. The included 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 process of flowing toward the second through hole 110. During the process of the accelerated airflow flowing toward the third through hole 114, it is accelerated again, so that the negative pressure effect generated at the third through hole 114 is better, and the debris is discharged more cleanly from inside the protective cover 106.

[0143] As Figure 24As shown, when the simulated air flow velocity is 3.6 m / s and blows from the front to the back in the outdoor operation setting, the angle of the first inclined surface 107 with the horizontal direction is 52°, and the angle of the third inclined surface 111 with the horizontal direction is 13.65°, the air flow velocities near the first through hole 108, the second through hole 110, and the third through hole 114 are as shown in the figure. When the air flow velocity is 3.6 m / s, outside the bottom of the protective cover 106, the air flow velocity near the first through hole 108 is 3.26 m / s, the air flow velocity near the second through hole is 5.15 m / s, and the air flow velocity near the third through hole 114 is 5.94 m / s. Obviously, when the air flow velocity is 3.6 m / s, the air flow velocity near the third through hole 114 is greater than that near the second through hole, and the air flow velocity near the second through hole is greater than that near the first through hole. Using the Bernoulli effect (the Bernoulli effect means that in a fluid, if the velocity is small, the pressure is large; if the velocity is large, the pressure is small. The Bernoulli effect applies to all ideal fluids including liquids and gases, and is one of the basic phenomena when the fluid is in steady flow, reflecting the relationship between the pressure and the flow velocity of the fluid. Specifically, the greater the flow velocity of the fluid, the smaller the pressure; the smaller the flow velocity of the fluid, the greater the pressure.), therefore, at the second through hole 110 and the third through hole 114, the air flow velocity outside the protective cover 106 is greater than that inside. In this way, a pressure towards the outside of the protective cover 106 will be generated at the second through hole 110 and the third through hole 114. In this way, when the air flows, a negative pressure effect is generated, and the debris and the like inside the protective cover 106 are discharged through the second through hole 110 and the third through hole 114.

[0144] As Figure 22 and Figure 23 , 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 decrease in sequence. Specifically, the bottom surface of the protective cover 106 is set as an inclined surface on the vehicle 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 decrease in sequence, while the flow velocities of the air flow passing through the first through hole 108, the second through hole 110, and the third through hole 114 increase in sequence. This makes the negative pressure effect generated at the second through hole 110 and the third through hole 114 greater than that at the first through hole 108, thereby helping to discharge the debris that enters the protective cover 106 through the first through hole 108 through the second through hole 110 and the third through hole 114, reducing the accumulation of debris inside the protective cover 106, and helping to dissipate the heat of the power management device 219 inside the protective cover 106.

[0145] As Figure 22 and Figure 23, 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 decrease in sequence. When the weight of the debris is large and the effect of discharging the debris by the negative pressure is limited, in order to facilitate the discharge of the debris and the like, the heights of the lowest ends of the first through hole 108, the second through hole 110, and the third through hole 114 are set to decrease in sequence, so that the vibration generated during the operation of the outdoor working equipment can be used to discharge the heavier debris and the like. In order to discharge the larger-volume debris, in an embodiment of the present application, the hole areas of the second through hole 110 and the third through hole 114 are designed to be larger, so that the heights of the upper ends of the second through hole 110 and the third through hole 114 are higher than the height of the first through hole 108.

[0146] As Figure 23 , in an embodiment, the third through hole 114 is designed to be a strip-shaped structure.

[0147] As Figure 23 , in an embodiment, a recess 112 is provided at the lower end of the protective cover 106 close to 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 formed by inward depression from the outside of the protective cover 106. The recess 112 formed by depression is composed of a bottom surface and multiple side surfaces, and the third through hole 114 is formed on one of the side surfaces. In this way, it can prevent the liquid from directly splashing onto the power protection device through the third through hole 114, and can also prevent other hard objects and impurities from directly hitting the power management device 219, so as to avoid damage to the power management device 219.

[0148] In an embodiment, in order to improve the heat dissipation effect, multiple recesses 112 are provided, and a third through hole 114 is provided corresponding to each recess 112. The arrangement of the multiple 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 outer side of the rear part of the power management device 219, and the orientations of the third through holes 114 are set to be away from or far from the power management device 219, so as to guide the liquid or hard objects entering the third through hole 114 not to directly splash or hit the power management device 219, preventing damage.

[0149] As Figure 18As shown, in one embodiment, a power supply fixing member 116 is provided on the vehicle frame 100. The power supply device 200 includes a battery compartment 201 for installing a battery pack. The battery compartment 201 is fixed above the power supply fixing member 116. A power management fixing bracket 105 is provided below the power supply fixing member 116. The power management device 219 is disposed on the power management fixing bracket 105. The power management device 219 is fixed below the battery pack through the power management fixing bracket 105 and is kept at a certain distance from the battery pack. This is beneficial to the respective heat dissipation between the battery pack and the power management device 219 and they do not affect each other.

[0150] As Figure 18 and Figure 21 shown, in a specific embodiment, the power management fixing bracket 105 includes a fixed leg 1051 and a fixing plate 1052 connected to each other. The fixed leg 1051 is used to be fixed to the power supply fixing member 116. The fixing plate 1052 is used to install the power management device 219. Vent holes 1053 are provided on the fixing plate 1052. The vent holes 1053 are used for ventilation, facilitating the flow of air and contributing to the heat dissipation of the upper surface of the power management device 219. A front baffle 1054 is provided at the front part of the fixing plate 1052. The front baffle 1054 extends downward and can protect the power management device 219. The front baffle 1054 is also provided with a baffle opening 1055. The baffle opening 1055 is correspondingly arranged with the power management device 219. When the outdoor working equipment moves forward, air flow can enter the baffle opening 1055, so that a flowing air flow is formed below the power management fixing bracket 105, which is beneficial to the heat dissipation of the power management device 219.

[0151] Referring to Figure 18 , in one embodiment, in order to optimize the structural layout, the battery compartment 201 of the present application includes two side plates 216 arranged correspondingly. Electric connection terminals 220 for connecting the battery pack are respectively provided on the two side plates 216. In the horizontal direction, the power management device 219 is located between the two side plates 216 and the power management device 219 can be electrically connected to the electric connection terminals 220 on the two side plates 216 respectively through wire harnesses. Installing the power management device 219 between the two side plates 216 respectively provided with the electric connection terminals 220 enables the power management device 219 to realize electrical connection with the electric connection terminals 220 by using shorter wire harnesses, saving wire harnesses and also saving the space reserved for wire routing.

[0152] Referring to Figures 5 to 8 and Figure 18, Specifically, three electrical connection terminals 220 are provided on each of the two side plates 216 of the battery compartment 201 arranged in the front-rear direction of the outdoor working device. Correspondingly, an interface 217 connected to the electrical connection terminal 220 at the front of the battery compartment 201 is provided at the front of the power management device 219, and an interface 217 connected to the electrical connection terminal 220 at the rear of the battery compartment 201 is provided at the rear of the power management device 219. This makes the spatial layout of the wiring harness of the electrical connection terminal 220 connected to the power management device more reasonable.

[0153] Please refer to Figure 20 , In one embodiment, the interface 217 at the front of the power management device 219 can be connected to the vehicle control module, the air flow generator 2031, and the electrical connection terminal 220 through a cable 222, and the position height is higher than the interface 217 at the front of the power management device 219. The height of the interface 217 at the front of the power management device 219 is higher than the lowest end of the front baffle 1054, and the cable 222 passes through the lowest end of the front baffle 1054 and is connected to the interface 217 at the front of the power management device 219. In this way, the lowest end of the cable 222 will be below the lowest end of the front baffle 1054. Since the connection height of the cable 222 with the vehicle control module, the air flow generator 2031, and the electrical connection terminal 220 is higher than the height of the interface 217 at the front of the power management device 219, with such a setting, when there is liquid on the cable 222, it will not flow into the power management device 219 along the cable 222, preventing the power management device 219 from getting damp, thus playing a very good protective role for the power management device 219.

[0154] Furthermore, the battery compartment 201 includes two relatively arranged side plates 216, and heat dissipation fans for dissipating heat from the battery pack are respectively provided on the two side plates 216. In the horizontal direction, the power management device 219 is located between the two side plates 216, and the power management device 219 can be electrically connected to the heat dissipation fans on the two side plates 216 through a wiring harness respectively. Such a setting also reasonably saves the wiring harness distance between the power management device 219 and the heat dissipation fans.

[0155] As Figure 1 and Figure 18 shown, in one embodiment, the lower surface of the power management device 219 is inclined towards the forward direction of the outdoor working device. With such a setting, when the outdoor work is advancing, the bottom surface of the power management device 219 can contact more with the air flow entering through the first through hole 108, increasing the contact area between the lower surface of the power management device 219 and the air flow, and improving the heat dissipation effect of the power management device 219.

[0156] Furthermore, the protective cover 106 is fixed to the vehicle frame 100 and is detachably connected to the vehicle frame 100 by screwing, which is convenient for disassembly and assembly.

[0157] As Figure 17 and Figure 18 shown, in one embodiment, an outdoor working device of the present application includes a vehicle frame 100; arranged on the vehicle frame 100 are: a power supply device 200, at least for supplying power to the outdoor working device; a power management device 219, fixed below the vehicle frame 100 and used for controlling charging or discharging of the power supply device 200; a protective cover 106, arranged below the power management device 219; wherein, the bottom of the power supply device 200, the vehicle frame 100 and the protective cover 106 form a protection space surrounding the power management device 219 to protect the power management device 219 and prevent external liquid or solid from damaging the power management device 219.

[0158] As Figure 23 , two connected convex portions 113 are protrudingly arranged towards the inside of the protective cover 106 at the bottom of the protective cover 106. The arrangement of the convex portions 113 can strengthen the strength of the protective cover 106. Secondly, the arrangement of the convex portions 113 also makes the extra space inside the protective cover 106 smaller. Moreover, the convex portions 113 are located between the second through hole 110 and the third through hole 114, so that debris entering the protective cover 106 can be discharged from the third through hole 114 under the delivery action of the convex portions 113, making it difficult for the debris to accumulate inside the protective cover 106.

[0159] As Figure 1 、 Figures 25 to 26 shown, in one embodiment, the present application includes: a vehicle frame 100, arranged on the vehicle frame 100 are: a traveling assembly 600, used for supporting the outdoor working device to travel; a power output assembly 500, used for performing outdoor operations; a seat 400, used for a user to sit; a power supply device 200, used for supplying power to the outdoor working device with a tail cover 210; the tail cover 210, arranged on the power supply device 200, and at least arranged on the tail cover 210 are: a reverse radar 213: the reverse radar 213 is used for monitoring the rear area when the outdoor working device is traveling in reverse; a tail lamp 214, and the tail lamp 214 at least shows the operating state of the outdoor working device with the tail cover 210.

[0160] In one embodiment, the tail cover 210 includes a main board 2101 located at the rear of the outdoor working device and auxiliary boards 2102 located on both sides of the outdoor working device and connected to the main board 2101; the power supply device 200 includes a battery compartment 201 for installing a battery pack. The battery compartment 201 includes a rear panel capable of installing a cooling fan and two side panels connected to the rear panel. The main board 2101 is correspondingly arranged with the rear panel, and the auxiliary boards 2102 are correspondingly arranged with the side panels. Such an arrangement enables the tail cover 210 to surround and protect the rear and sides of the battery compartment 201, so as to reduce the direct impact on the battery compartment 201 and the battery pack inside the battery compartment 201 in case of a collision, and also makes the rear part of the entire outdoor working device beautiful and concise.

[0161] As Figure 27 shown, in one embodiment, the tail lamp 214 includes a main lamp part 2141 located on the main board 2101 and auxiliary lamp parts 2142 extending from both ends of the main lamp part 2141 to the auxiliary boards 2102; when the user is located on the side or rear of the outdoor working device, the state of the tail lamp 214 can be observed. Such an arrangement is beneficial for the user to directly observe the flashing of the tail lamp 214 at multiple positions, and helps the user understand whether the battery pack and the battery compartment 201 are installed in place.

[0162] As Figure 28 shown, the power supply device 200 includes a battery compartment 201 for installing a battery pack. A tail cover 210 is connected to the battery compartment 201, and a receiving space 211 is formed between the tail cover 210 and the battery compartment 201. The reverse radar 213 is located in the receiving space 211, which plays a protective role for the reverse radar 213.

[0163] As Figure 28 shown, in one embodiment, a cooling fan for cooling the battery pack is provided on a side plate 216 of the battery compartment 201. A receiving space 211 is formed between the tail cover 210 and the battery compartment 201. The cooling fan and the wire harness connecting the cooling fan are located in the receiving space 211. Such an arrangement can protect the cooling fan and its wire harness while ensuring that the cooling fan has space for air circulation, and prevent sundries from contaminating the cooling fan and the wire harness.

[0164] As Figure 16 shown, in one embodiment, a charging connector 218 is further provided on the battery compartment 201. By directly installing the charging connector 218 on the battery compartment 201, the battery pack in the battery compartment 201 can be directly charged through the charging connector 218.

[0165] In one embodiment, the charging connector 218 is arranged at an angle with the horizontal direction. The angle between the charging connector 218 and the horizontal direction can be greater than or equal to 0° and less than or equal to 90°, preferably 45° and 60°. Such designs of 45° and 60° angles help users to plug and unplug the charging gun from the charging connector 218.

[0166] Meanwhile, referring to Figure 27 as shown, in one embodiment, a mounting seat 223 for installing the charging connector 218 is provided on the battery compartment 201. The tail cover 210 is installed on the mounting seat 223. A charging avoidance opening 212 for the charging connector 218 to expose is provided on the tail cover 210. The charging connector 218 passes through the charging avoidance opening 212 of the tail cover 210 and is connected to the charging gun.

[0167] Please also refer to Figure 19 , in one embodiment, the mounting seat 223 includes a mounting surface 2231. The surface of the mounting surface 2231 faces the upper rear of the outdoor working device. A perforation is provided on the mounting surface 2231. A fitting flat plate 2181 is provided on the charging connector 218. The charging connector 218 is provided on both sides of the fitting flat plate 2181. During installation, one end of the charging connector 218 passes through the perforation so that the fitting flat plate 2181 can be attached to the mounting surface 2231, and then the two are fixedly connected by screws. Since the surface of the mounting surface 2231 faces the upper rear of the outdoor working device, such a setting enables the charging connector 218 to be inclined upward at an angle toward the upper rear of the outdoor working device when the charging connector 218 is installed on the mounting surface 2231, so as to be connected to the charging gun.

[0168] In one embodiment, the angle between the mounting surface 2231 and the horizontal direction is greater than or equal to 0° and less than or equal to 90°, preferably 45° and 60°, so that the charging connector 218 installed on the mounting surface 2231 can be inclined backward at 45° or 60°. The angle setting is reasonable and convenient for users to plug and unplug the charging gun.

[0169] Furthermore, the mounting seat 223 further includes a first panel 2237 connected to the mounting surface 2231 and a second panel 2238 connected to the first panel 2237, and the first panel 2237 and the second panel 2238 are located inside the lower part of the mounting surface 2231. In this way, while supporting the mounting surface 2231, the occupied space is small.

[0170] In one embodiment, the mounting seat 223 corresponds to a temperature control component. In order not to affect the exhaust or intake of the temperature control component, exhaust holes 2232 are provided on the first panel 2237, the second panel 2238 and the side surface of the mounting surface 2231 in this application, which is beneficial to the exhaust or intake of the temperature control component.

[0171] In one embodiment, a connecting portion 2233 is further provided below the second panel 2238. The connecting portion 2233 is used to connect with the power supply fixing member 116, making the installation of the mounting seat 223 more firm.

[0172] In one embodiment, a connecting auxiliary plate 2234 is provided on the side of the mounting seat 223. A radar controller 2235 is provided on the connecting auxiliary plate 2234. The radar controller 2235 is electrically connected to the reverse radar 213.

[0173] In one embodiment, the tail lamp 214 is provided above the tail cover 210. A charging connector 218 is provided below the tail lamp 214, and the charging connector 218 is provided at the middle position of the tail cover 210. The reverse radars 213 are provided on both sides of the charging connector 218 and are arranged substantially flush with the reverse radars 213.

[0174] In one embodiment, the reverse radar 213 can be directly mounted on the battery compartment 201, or the reverse radar 213 can be mounted on the vehicle frame 100. Of course, the reverse radar 213 can also be mounted on the seat 400, and corresponding selection and design can be made according to actual usage requirements.

[0175] As Figure 25 and Figure 26 shown, according to the ergonomic analysis, in the horizontal direction, with the extending direction of the vehicle frame 100 as the center line Z, the vehicle frame 100 is symmetrically distributed left and right. The center of the seat 400 is located on the center line Z. When the driver is sitting still on the outdoor working equipment, the area about 30° on the left and right of the center line Z in front of the driver (the included angle of the S1 area is 60°) is the best visual field area, and the area about 60° on the left and right (the included angle of the S2 area is 120°) is the normal binocular clear visual field area. The area within the included angle range of 60° to 95° on one side (S3 area) is the visible blurred area.

[0176] Since the driver is always in a moving state when driving and operating the vehicle, the effective visual perception angle will be reduced compared to the static state. According to the ergonomic theory, the double-view clear area of 120° is used as the reference data. It can be seen from the visual field simulation diagram that when the driver is operating normally (holding the operation component 300), the maximum clear visual field area that can be obtained by turning the head left and right is 300° (S4 area), and there is a visual blind area with an included angle of 60° at the exact rear of the vehicle (S2 area).

[0177] As Figure 25 and Figure 26As shown in the figure, in order to make up for the visual blind area with a 60° included angle directly behind the vehicle, in one embodiment, the outdoor working equipment of the present application includes a vehicle frame 100; a traveling assembly 600, which is arranged on the vehicle frame 100 and is configured to support the outdoor working equipment to travel; a cutting assembly, which is arranged on the vehicle frame 100 and is configured to cut vegetation; a seat 400, which is arranged on the vehicle frame 100 and is configured for a user to sit on. When the user operates the outdoor working equipment on the seat 400, the visual field range in the horizontal direction can at least cover the front and both sides of the outdoor working equipment by 300°; a detection assembly, which is arranged at the rear of the outdoor working equipment, and the detection assembly detects at least a 60° range in the horizontal direction. Among them, the visual field range of the user and the detection range of the detection assembly can cover the four sides of the outdoor working equipment at all angles in the horizontal direction.

[0178] As Figure 26 shown, in one embodiment, the length range of the spatial area (S6) at least detected by the detection assembly is 1.4 m to 1.6 m, the width range is 1.5 m to 1.7 m, and the height range is: 1.1 m to 1.3 m.
