Apparently, 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.

[0066] In the description of this application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0067] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0068] Please refer to Figures 1 to 42 shown is an outdoor working device according to an embodiment disclosed in this application. The outdoor working device includes a vehicle frame 100, a power supply device 200, an operation component 300, a seat 400, a power output component 500, and a traveling component 600.

[0069] The frame 100 is arranged to extend in a direction. The power supply device 200 is arranged at the rear part of the 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 equipment. 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, so as to increase the adaptability of the outdoor working equipment 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 equipment of the present 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.

[0070] 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.

[0071] 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 equipment. The user controls the left operation lever and the right operation lever to control the outdoor working equipment to move forward, backward or turn. The operation assembly 300 can also be a steering wheel capable of controlling the outdoor working equipment.

[0072] In one embodiment, control buttons for adjusting the running 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 equipment. Further, buttons for adjusting the brightness of the vehicle lights of the outdoor working equipment can also be arranged on the operation assembly 300.

[0073] The seat 400 is arranged on the frame 100, and the left operation lever and the right operation lever are arranged close to the seat 400 and on the left and right sides of the seat 400, so that the user sitting on the seat 400 can control the left operation lever and the right operation lever to control the operation of the outdoor working equipment.

[0074] As a workpiece for realizing the tool function, in one embodiment, the outdoor working equipment is a ride-on mower, and the power output assembly 500 is specifically a cutting assembly and is arranged below the frame 100. It is used to output power to realize the mowing function of the ride-on mower. The cutting assembly is arranged in 2 groups or 3 groups.

[0075] In one embodiment, the cutting assembly includes: a cutter head, a mowing element, and a cutting motor. The cutting motor is controlled by a control button on the operation assembly 300. 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 vegetation on a lawn. The cutter head forms a mowing space for accommodating the mowing element, and the mowing element is at least partially located within the mowing space. In some embodiments, the number of mowing elements can be two, and correspondingly, the number of cutting motors is also two. The two cutting motors independently drive the two mowing elements respectively. In some embodiments, the number of mowing elements can be three, and correspondingly, the number of cutting motors is also three. The three cutting motors independently drive the three mowing elements respectively.

[0076] 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 with other components to meet the usage requirements of different gardening operations. Therefore, the outdoor garden mower can not only cut vegetation, but also replace the cutting assembly 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.

[0077] When the cutting assembly is replaced with functional components such as snow shoveling, snow sweeping, and snow blowing, the power supply device 200 of the outdoor working device of the present application can also adapt to a relatively cold environment and supply power to the above-mentioned functional components such as snow shoveling, snow sweeping, and snow blowing.

[0078] The traveling assembly 600 includes traveling wheels provided on the vehicle frame 100 and a traveling motor for driving the traveling wheels. The traveling wheels are provided 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 tipping over during traveling.

[0079] In one embodiment, the number of traveling wheels is set to four, including 2 front traveling wheels 601 and 2 rear traveling wheels 602 respectively. The front traveling wheels 601 can be universal wheels. The traveling motor is connected to the rear traveling wheels 602 and drives the rear traveling wheels 602 to rotate. The 2 rear traveling wheels 602 are both matched with the traveling motor. The rotational speeds of the 2 traveling motors can be the same or different. When the user drives the outdoor working device straight, the rotational speeds of the two traveling motors are approximately the same; when the user drives the outdoor working device to turn, the rotational speeds of the two traveling motors are different, and the outdoor working device turns towards the side with the lower rotational speed of the traveling motor. In some embodiments, the diameter of the front traveling wheels 601 is smaller than the diameter of the rear traveling wheels 602.

[0080] In one embodiment, please refer to Figure 2 、 Figure 3 and Figure 4, the power supply device 200 is at least used to supply power to outdoor working equipment. The power supply device 200 includes a battery compartment 201. A first type of battery pack 205 or a second type of battery pack 206 can be installed in the battery compartment 201, or both the first type of battery pack 205 and the second type of battery pack 206 can be installed simultaneously. Among them, the first type of battery pack 205 and the second type of battery pack 206 can be respectively installed in the battery compartment 201 in a detachable manner.

[0081] The first type of battery pack 205 and the second type of battery pack 206 can also be detached from the battery compartment 201 to supply power to other tools.

[0082] Refer to Figure 2 、 Figure 3 and Figure 4 , a plurality of temperature control components 203 are further provided on the battery compartment 201. The plurality of temperature control components 203 perform temperature control operations by obtaining the electrical energy of the battery pack on the outdoor working equipment. The plurality of temperature control components 203 are configured to be able to perform temperature control on the first type of battery pack 205 and / or the second type of battery pack 206. In one embodiment, the temperature control operation includes two methods: heating and cooling. In this application, heating or cooling of the first type of battery pack 205 and / or the second type of battery pack 206 can be selected according to actual needs.

[0083] Of course, the energy obtained by the plurality of temperature control components 203 can be either the first type of battery pack 205 or the second type of battery pack 206 in the battery compartment 201, or other energy-supplying battery packs on the outdoor working equipment.

[0084] Refer to Figure 2 、 Figure 3 and Figure 4 , specifically, when the first type of battery pack 205 and the second type of battery pack 206 need to be cooled, the temperature control component 203 is an air flow generator 2031 capable of generating air flow, specifically, it can be a cooling fan, which is used to cool the first type of battery pack 205 and the second type of battery pack 206.

[0085] When the first type of battery pack 205 and the second type of battery pack 206 need to be heated, the temperature control 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 of battery pack 205 and the second type of battery pack 206 for heating treatment.

[0086] Such as Figure 2 and Figure 4As shown, in one embodiment, when the number of the first type of battery packs 205 loaded into the battery compartment 201 is x, the number of the temperature adjustment components 203 configured to be able to adjust the temperature of the first type of battery packs 205 is x. Specifically, the number of the temperature adjustment components 203 configured to adjust the temperature of x first type of battery packs 205 at any time is x.

[0087] In one embodiment, when the internal temperatures of m first type of battery packs 205 among the x first type of 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 adjustment components 203 to adjust the temperature of the m first type of battery packs 205 with internal temperatures within the first range value until the temperature is adjusted to the normal range value.

[0088] Setting the number of the first type of battery packs 205 and the number of the temperature adjustment components 203 in a one-to-one matching manner is to meet the requirement that although the temperature of the first type of battery packs 205 during charging and discharging is different from the temperature in the normal range value, when the temperature adjustment requirement is limited, one temperature adjustment component 203 can meet the heat dissipation or heating requirement of one first type of battery pack 205, and the first type of battery packs 205 with temperatures within the normal range value do not need temperature adjustment. Since the energy source of the temperature adjustment component 203 also comes from the battery pack, it can save the electric energy of the battery pack and improve the endurance of the battery pack.

[0089] 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 adjustment component 203 only starts the air flow generator 2031 to dissipate heat from the first type of battery packs 205, so that the temperature inside the first type of battery packs 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 adjustment 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 of battery packs 205 to perform a heating process on the first type of battery packs 205, so as to raise the temperature inside the first type of battery packs 205 to the normal range value, which is helpful for the charging or discharging of the battery pack.

[0090] 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.

[0091] 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 perform temperature regulation processing on the first type of battery pack 205, thereby ensuring the normal charge and discharge requirements of the first type of battery pack 205.

[0092] 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 performed 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 performed on the first type of battery pack 205 or the second type of battery pack 206.

[0093] 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.

[0094] As Figure 3 and Figure 4 As shown, 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.

[0095] 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 usually 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.

[0096] In one embodiment, when the number of the y second-type battery packs 206 installed in the battery compartment 201 with internal temperatures within the first range value is n, the power management device 219 activates 2n temperature control components 203 to perform temperature control processing on the n second-type battery packs 206 with internal temperatures within the first range value.

[0097] 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 of the second-type battery packs 206 during charging and discharging, where one temperature control component 203 cannot meet the demand, and two temperature control components 203 are required to meet the heat dissipation or temperature increase requirements of one second-type battery pack 206. The second-type battery packs 206 with temperatures within the normal range value do not undergo temperature control processing. 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 power of the battery packs is saved, and the battery life of the battery packs is improved.

[0098] In one embodiment, when the number of the y second-type battery packs 206 installed in the battery compartment 201 with internal temperatures 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 the n second-type battery packs 206 with internal temperatures within the second range value, and at most all the temperature control components 203 on the outdoor working device perform temperature control processing on the n second-type battery packs 206 with internal temperatures within the second range value.

[0099] As Figures 2 to 8 shown, in one embodiment, the battery compartment 201 includes two side plates 216 arranged oppositely. Each side plate 216 is provided with a temperature control component 203, 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. Electric connection terminals 220 are respectively arranged near each temperature control component 203 on the battery compartment 201, and the multiple electric connection terminals 220 are respectively arranged on the two oppositely arranged side plates 216; One power connection terminal 2051 is arranged on the first-type battery pack 205. When the first-type battery pack 205 is installed in the battery compartment 201, one power connection terminal 2051 is connected to one electric connection terminal 220; Two power connection terminals 2061 are arranged at both ends of the second-type battery pack 206. 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.

[0100] As Figure 5 and Figure 6 shown, in one embodiment, the battery compartment 201 includes two side plates 216 disposed opposite to each other. 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 out of alignment with other mounting positions 224. The misaligned arrangement of the mounting positions 224 helps to enhance the structural strength of the battery compartment 201.

[0101] In one embodiment, the misalignment distance between the paired and misaligned mounting positions 224 and other mounting positions 224 is 20 mm to 40 mm, and the preferred misalignment distances are 20 mm, 30 mm, and 40 mm.

[0102] As Figures 5 to 8 shown, further, an electrical connection terminal 220 is provided on each mounting position, so that at least one pair of electrical connection terminals 220 is arranged out of alignment with other electrical connection terminals 220.

[0103] As Figures 5 to 8 shown, in a specific embodiment, three air flow exchange parts 204 are respectively provided on two correspondingly arranged 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 adjustment component 203 is provided corresponding to each air flow exchange part 204. Therefore, six temperature adjustment components 203 are also provided. Correspondingly, six electrical connection terminals 220 are also provided on the two side plates 216 of the battery compartment 201. One side plate 216 is provided with three, and the other side plate 216 is also provided with three, and each electrical connection terminal 220 is provided in the upper region of the air flow exchange part 204.

[0104] As Figures 2 to 4 shown, the battery compartment 201 has an open opening for loading and unloading the first type of battery pack 205 and / or the second type of battery pack 206. A cover 202 is provided corresponding to the opening. The cover 202 is used to cover the opening 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.

[0105] As Figures 5 to 8 shown, a plurality of air flow exchange parts 204 are provided on two correspondingly arranged side plates 216 of the battery compartment 201, and a temperature adjustment component 203 is correspondingly matched with one air flow exchange part 204. The temperature adjustment component 203 can exhaust and intake air into the battery compartment 201 through its corresponding air flow exchange part 204.

[0106] As Figures 5 to 8 shown, in one 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, so as to dissipate heat from the first type of battery pack.

[0107] As Figures 5 to 8 shown, further, when the temperature inside the first type of battery pack 205 is within the second range value, the power management device 219 will mobilize multiple temperature control components 203 to perform temperature control processing on the first type of battery pack 205. The multiple 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.

[0108] As Figures 3 to 8 In one 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 through the air flow exchange part 204 simultaneously, exhaust air simultaneously, or one blows air and the other exhausts air. Preferably, the two temperature control components 203 are respectively arranged 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 power connection terminals 220 located on the battery compartment 201 corresponding thereto, and the two temperature control components 203 are near the power connection terminals 220 on the two side plates 216. Therefore, the temperature control components 203 can also dissipate the heat generated when the power connection terminals 220 and the power connection terminals 2061 are in contact.

[0109] Further, when the internal temperature of the second type of battery pack 206 is within the second range value, multiple temperature control components 203 can blow air to the second type of battery pack 206 installed in the battery compartment 201 through the air flow exchange part 204 simultaneously, exhaust air simultaneously (exhaust air to the outside), or at least one blows air inward and at least one exhausts air to the outside (exhaust air to the outside).

[0110] Please also refer to Figure 2 、 Figure 4 、 Figure 14 and Figure 15As shown, in one embodiment, to improve the heat dissipation or heating effect, 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 control component 203 performs temperature control 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 by the way of air outlet through the first vent 2052 and air inlet through the second vent 2053, so that the heat in the first type of battery pack 205 is quickly dissipated to reach the normal range value, or the first type of battery pack 205 is heated by air inlet through the first vent 2052 and air outlet through the second vent 2053, so that the temperature in the first type of battery pack 205 rises rapidly, so that the temperature in the first type of battery pack 205 reaches the normal range value.

[0111] Please also refer to Figure 2 、 Figure 4 、 Figure 12 、 Figure 13 、 Figure 16 and Figure 17 As shown, 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 parts 204 provided on two corresponding side plates 216 of the battery compartment 201. By providing two air flow exchange parts 204 to ventilate and dissipate heat for one second type of battery pack, it is beneficial for the temperature control component 203 to take away the heat inside the second type of battery pack 206 through the air flow exchange parts 204, or to quickly raise the temperature inside the second type of battery pack 206 through the air flow exchange parts 204, so that the second type of battery pack 206 quickly returns to the normal temperature range value.

[0112] In one embodiment, when the second type of battery pack 206 needs to be heat-dissipated, the power management device 219 can control the air flow generator 2031 in the temperature control component 203 to operate and the heater not to 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 to the outside 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 is quickly cooled to the normal range value.

[0113] 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, and blow air to the third vent 2062 and the fourth vent 2603 of the second type of battery pack 206 at the same time. At the same time, a fifth vent 2064 is also provided on the housing of the second type of battery pack 206, which can discharge the cold air in the second type of battery pack 206, so that the temperature in the second type of battery pack 206 can be quickly raised to the normal range value. In a specific embodiment, the fifth vent 2064 is provided on both sides of the power connection terminal on the battery pack.

[0114] As Figure 18 , in one embodiment, the power supply device 200 includes: a power supply unit, in which a temperature detection module for detecting the temperature of the power supply unit is provided; a battery compartment 201 for assembling the power supply unit; a power management module, electrically connected to the temperature detection module and processing the temperature information transmitted by the temperature detection module; a plurality of temperature control components 203 are electrically connected to the power management module; wherein, when the temperature 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 power supply unit; when the temperature detected by the temperature detection module is within the second range value, the power management module controls the temperature control component 203 to continue heating or cooling the battery pack, and the power supply unit charges or discharges with a low current.

[0115] Specifically, the power supply unit includes a first type of battery pack 205 or a 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 in both the first type of battery pack 205 and the second type of battery pack 206 for detecting the temperatures in 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 in 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 in the first type of battery pack 205 or the second type of battery pack 206; when the temperature in 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 a 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 charges or discharges with a low current until the charge and discharge are completed.

[0116] In one embodiment, the temperature control 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.

[0117] In one embodiment, the temperature control 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.

[0118] 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.

[0119] Such as Figure 2 and Figure 18 In one 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 control components 203 configured to control 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 control components 203 configured to control the temperature of 1 first type of battery pack 205 is 1.

[0120] In one 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 control components 203 configured to control the temperature of m first type of battery packs 205 is at least m + 1 and at most all the temperature control components 203 on the outdoor working device.

[0121] 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 control components 203 configured to control the temperature of 1 first type of battery pack 205 is at least 2 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 2, 3, or 5 temperature control components 203 can work, but at most 6 temperature control components 203 simultaneously perform heat dissipation or temperature increase processing for 1 first type of battery pack 205.

[0122] 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 control components 203 dissipate heat from the first type of battery pack 205.

[0123] Such as Figure 3 andFigure 18 In an 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.

[0124] In an 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 an embodiment, there are 6 temperature control components 203, and at most 6 temperature control components 203 simultaneously perform heat dissipation or temperature increase processing 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.

[0125] 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 runs again to perform temperature adjustment processing on the first type of battery pack 205 or the second type of battery pack 206.

[0126] The first range value, the second range value, and the normal range value are not limited to a specific range value and are floating, and can be adjusted according to different usage requirements.

[0127] Please also refer to Figure 18 and Figure 40 In an embodiment, the temperature detection module inside the battery pack (the first type of battery pack 205 and / or the second type of battery pack 206) detects the temperature inside the battery pack and transmits the detected temperature inside the battery pack to the power management device 219. The power management device 219 determines that the detected temperature exceeds the threshold value to perform corresponding processing.

[0128] In the charging state, when the temperature detected inside the battery pack is higher than 35°, the power management device 219 turns on the air flow generator 2031 (heat dissipation fan) corresponding to the battery pack. The air flow generator 2031 operates to generate an air flow, and blows air on the battery pack for heat dissipation through the air flow exchange part 204 on the battery compartment 201; when the temperature detected inside the battery pack is less than or equal to 30°, the power management device 219 turns off the air flow generator 2031 corresponding to the battery pack to save the power consumption of the air flow generator 2031 and conserve the electrical energy of the battery pack. This process of inquiring and judging the situation of each battery pack is repeated alternately.

[0129] In the discharging state: when the temperature detected inside the battery pack is higher than 45°, the power management device 219 turns on the air flow generator 2031 (heat dissipation fan) corresponding to the battery pack. The air flow generator 2031 operates to generate an air flow, and blows air on the battery pack for heat dissipation through the air flow exchange part 204 on the battery compartment 201; when the temperature detected inside the battery pack is less than or equal to 40°, the power management device 219 turns off the air flow generator 2031 corresponding to the battery pack.

[0130] When the feedback signal of the air flow generator 2031 is in a protection state (such as short circuit, overcurrent, overheating, communication anomaly, etc. of the air flow generator 2031), the power management device 219 turns off the air flow generator 2031 and reports the specific situation of the protection state to the vehicle management module.

[0131] Please also refer to Figure 18 and Figure 41 , in another embodiment, the temperature detection module inside the battery pack (the first type of battery pack 205 and / or the second type of battery pack 206) detects the temperature inside the battery pack and transmits the detected temperature inside the battery pack to the power management device 219. The power management device 219 judges that the detected temperature exceeds the threshold value to perform corresponding processing.

[0132] In the charging state, when the temperature detected inside the battery pack is higher than 35°, the power management device 219 turns on all the air flow generators 2031 on the battery compartment 201 for cooling the battery pack. The air flow generators 2031 operate to generate an air flow, and blow air on the battery pack for heat dissipation through the air flow exchange part 204 on the battery compartment 201; when the temperature detected inside the battery pack is less than or equal to 30°, the power management device 219 turns off all the air flow generators 2031 on the battery compartment 201 to save the power consumption of the air flow generators 2031 and conserve the electrical energy of the battery pack.

[0133] In the discharge state: When the temperature inside the battery pack detected is higher than 45°, the power management device 219 turns on all the air flow generators 2031 on the battery compartment 201 for cooling the battery pack. The air flow generators 2031 operate to generate an air flow, and blow air to dissipate heat from the battery pack through the air flow exchange part 204 on the battery compartment 201; When the temperature inside the battery pack detected is less than or equal to 40°, the power management device 219 turns off all the air flow generators 2031 on the battery compartment 201 to save the power consumption of the air flow generators 2031 and conserve the electric energy of the battery pack.

[0134] When the feedback signal of the air flow generator 2031 is in a protected state (such as the air flow generator 2031 being in a short - circuit, over - current, over - temperature, communication anomaly, etc. situation), the power management device 219 turns off the air flow generator 2031 and reports the specific situation of the protected state to the vehicle management module.

[0135] Please also refer to Figure 18 and Figure 42 , in another embodiment, multiple battery packs are set as a group, and multiple groups are set in total. In the charging state, when the temperature inside a single or multiple battery packs in the detected group is higher than 35°, the power management device 219 turns on multiple air flow generators 2031 that match the corresponding group. The multiple air flow generators 2031 operate to generate an air flow, and blow air to dissipate heat from the battery pack through the air flow exchange part 204 on the battery compartment 201; When the temperature inside the battery pack detected is less than or equal to 30°, the power management device 219 turns off all the air flow generators 2031 of this group to save the power consumption of the air flow generators 2031 and conserve the electric energy of the battery pack.

[0136] In the discharge state: When the temperature inside a single or multiple battery packs in the detected group is higher than 45°, the power management device 219 turns on multiple air flow generators 2031 that match the corresponding group. The multiple air flow generators 2031 operate to generate an air flow, and blow air to dissipate heat from the battery pack through the air flow exchange part 204 on the battery compartment 201; When the temperature inside the battery pack detected is less than or equal to 40°, the power management device 219 turns off all the air flow generators 2031 of this group to save the power consumption of the air flow generators 2031 and conserve the electric energy of the battery pack.

[0137] When the feedback signal of the air flow generator 2031 is in a protected state (such as the air flow generator 2031 being in a short - circuit, over - current, over - temperature, communication anomaly, etc. situation), the power management device 219 turns off the air flow generator 2031 and reports the specific situation of the protected state to the vehicle management module.

[0138] In one embodiment, when the battery pack is used for discharging, regardless of the number of battery packs installed in the battery compartment 201, as long as the battery pack is installed in the battery compartment 201, all the electric fans in the battery compartment 201 operate to dissipate heat from the battery pack.

[0139] In another embodiment, when charging the battery packs in the battery compartment 201, regardless of the number of battery packs in the battery compartment 201, as long as the charging gun is inserted into the charging connector 218 to charge the battery packs in the battery compartment 201, all the electric fans in the battery compartment 201 will start operating to dissipate heat from the battery packs.

[0140] As Figure 9 and Figure 11 shown, in one embodiment, an installation groove 207 is provided on the battery compartment 201 and on the outer periphery of the air flow exchange portion 204. The temperature adjustment assembly 203 includes an installation bracket 2032, an air flow generator 2031 and a heater fixed to the installation bracket 2032; when the installation bracket 2032 is installed and fitted with the installation groove 207, the air flow exchange portion 204 corresponds to the air outlet of the air flow generator 2031. Such a setting can achieve the quick disassembly and assembly of the temperature adjustment assembly 203 on the battery compartment 201, so as to facilitate the replacement and maintenance of the temperature adjustment assembly 203. Specifically, the air flow generator 2031 is fixed to the installation bracket 2032 by screws. A guide rail 2033 is provided on the installation bracket 2032, and the guide rail 2033 cooperates 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.

[0141] In one embodiment, the bottom of the installation bracket 2032 is a fixing portion 2034, and a fixing position 2035 is provided on the fixing portion 2034. Fixing members such as bolts can fix the fixing portion 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 in sliding fit with the installation groove 207 in place, the installation bracket 2032 can be fixed to the battery compartment 201 by fixing members such as screws.

[0142] As Figures 5 to 8 、 Figure 10 and Figure 11 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 discharge 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.

[0143] As Figure 1 、 Figure 3 and Figure 12As shown, in one embodiment, the present application includes a traveling assembly 600 for supporting the outdoor working equipment to travel; a power supply device 200, and the power supply device 200 includes: a battery compartment 201, on which a heat dissipation fan is provided, and an air flow is generated when the heat dissipation fan operates; a battery pack detachably assembled in the battery compartment 201, and the battery pack includes a battery housing 2065 and a plurality of battery cells 2068 located in the battery housing 2065.

[0144] As Figure 12 and Figure 13 , in one embodiment, the battery housing 2065 has a rectangular structure, and the battery housing 2065 includes a first housing 2067 perpendicular to the axial direction of the battery cells 2068 and a second housing 2066 parallel to the axial direction of the battery cells 2068. The first housing 2067 and the second housing 2066 are perpendicular to each other. A first air hole is provided on the first housing 2067, and a second air hole is provided on the second housing 2066; the air flow generated when the heat dissipation fan operates can enter the battery housing 2065 through the first air hole, and the air flow entering the battery housing 2065 flows through the battery cells 2068 and then is discharged through the second air hole. The air flow enters the battery housing 2065 through the first air hole, flows through the battery cells 2068, and then is discharged through the second air hole. In this way, the heat generated by the battery cells 2068 can be taken away, achieving the purpose of cooling the entire battery pack, so that the battery pack can be charged or discharged within a suitable temperature range, achieving a better charging or discharging effect.

[0145] As Figure 13 , Figure 16 and Figure 17 shown, in one embodiment, the battery pack can be a second type of battery pack 206, the first air hole is a fifth ventilation hole 2064, and the second air hole is a third ventilation hole 2062 or a fourth ventilation hole 2063.

[0146] In one embodiment, the intake direction of the first air hole is perpendicular to the outlet direction of the second air hole.

[0147] As Figure 13 , to increase the intake air volume per unit time, the number of the first air holes provided on the first housing 2067 can be multiple. In one embodiment, there are two first housings 2067 and they are respectively on both sides of the battery housing 2065. There are two first air holes provided on each side of the first housing 2067, and each first air hole is composed of a plurality of honeycomb holes. The setting of the plurality of honeycomb holes can prevent larger-volume sundries from entering the battery housing 2065 while ensuring air intake.

[0148] As Figures 5 to 8 , Figure 12 and Figure 13As shown, in one embodiment, an air flow exchange part 204 is provided on the battery compartment 201. The blowing direction of the cooling fan is the same as and on the same straight line with the air flow direction flowing through the air flow exchange part 204 and the air flow direction flowing through the second air hole. Such a setting enables the air flow entering the battery housing 2065 through the first air hole to flow around the battery cell 2068 and then be discharged from the battery housing 2065 through the second air hole. The air flow discharged from the battery housing 2065 is then discharged from the battery compartment 201 through the air flow exchange part 204, achieving the purpose of discharging the hot air flow inside the battery pack from the battery compartment 201 by utilizing the flow of the above-mentioned air flow.

[0149] As Figures 5 to 8 , Figure 12 and Figure 13 As shown, in one embodiment, the battery compartment 201 includes two oppositely arranged side plates 216. A cooling fan is provided on each side plate 216, and the cooling fans on one side plate 216 are arranged in one-to-one correspondence with the cooling fans on the other side plate 216; in the axial direction perpendicular to the battery cell 2068, second air holes are provided on the second housings 2066 at both ends of the battery housing 2065, and air flow exchange parts 204 are provided on both of the two oppositely arranged side plates 216; when the battery pack is installed in the battery compartment 201, the second air holes correspond to the air flow exchange parts 204. In one embodiment, when the battery pack is installed in the battery compartment 201 and the cooling fans are operating, the cooling fans are controlled to pump air out of and exhaust air outside the battery compartment 201. A plurality of first air holes on both sides of the above-mentioned battery housing 2065 are used for air intake. The air flow entering the battery housing 2065 flows around the battery cell 2068 inside the battery housing 2065, and the flowing air flow is used to take away the hot air near the battery cell 2068. At this time, the flowing hot air is then discharged from the battery housing 2065 through the second air holes at both ends of the battery housing 2065, and then the hot air is respectively discharged through the air flow exchange parts 204 on the two oppositely arranged side plates 216, thereby achieving the purpose of cooling the battery pack.

[0150] As Figures 2 to 4 As shown, in one embodiment, a cover 202 is provided at the opening of the battery compartment 201 of the present application. A gap is formed between the battery compartment 201 and the cover 202, and air flow can enter the interior of the battery compartment 201 through the gap between the battery compartment 201 and the cover 202 to compensate for the hot air discharged by the cooling fans.

[0151] Please also refer to Figures 2 to 4 , Figure 19 , Figure 25 and Figure 26, in one embodiment, the outdoor working device of the present application further includes a battery compartment 201 having an opening.

In one embodiment, a plurality of cooling fans are provided, and a cooling fan is provided under each first terminal. The cooling fan located under the first terminal is connected to the power management device 219 through a wiring harness and the same wiring hole 1161 under the first terminal.

With such an arrangement, the radar controller 2235 will not affect the blowing effect of the cooling fans, and at the same time, it will not be affected by the hot air blown by the cooling fans for its normal use.

[0161] Please refer to Figures 5 to 8 As shown, in one embodiment, a plurality of air flow exchange parts 204 are provided on the side plate 216 where the cooling fans are installed, and one air flow exchange part 204 is adjacent to one cooling fan in terms of spatial position.

[0162] Such as Figure 3 、 Figure 12 、 Figure 13 and Figure 27As shown, in one embodiment, the outdoor working device of the present application includes a battery compartment 201 with an opening. The battery compartment 201 further includes a bottom plate and a plurality of side plates 216 surrounding the bottom plate. At least one upper end of the inner wall of the side plate 216 is provided with a first terminal, and a lower end is provided with an air flow exchange part 204 communicating the inside and outside of the battery compartment 201; a battery pack, configured to be detachably assembled in the battery compartment 201. The upper end of the battery pack along its assembly direction is provided with a second terminal capable of being electrically connected to the first terminal in an electrical signal, and a lower end is provided with a second air hole corresponding to the air flow exchange part 204; when the battery pack is assembled in the battery compartment 201, the first terminal is electrically connected to the second terminal in an electrical signal, and the air flow exchange part 204 corresponds to the first air hole. When the first terminal is electrically connected to the second terminal for charging or discharging, the battery pack can exhaust air to the outside through the second air hole on it, and the gas discharged from the second air hole is discharged outside the battery compartment 201 through the air flow exchange part 204.

[0163] In the present application, the battery pack is installed in the up and down direction. It is defined that above the side plate 216 is the upper end and below the side plate 216 is the lower end in the assembly direction of the battery pack.

[0164] As Figures 5 to 8 , in one embodiment, a cooling fan corresponding to the air flow exchange part 204 is provided on the outer wall of the side plate 216. When the battery pack is assembled in the battery compartment 201, the air flow exchange part 204 corresponds to the second air hole and the cooling fan respectively. Such a setting enables the cooling fan to directly use the negative pressure generated during its operation to discharge the gas passing through the air flow exchange part 204 outside the battery compartment 201.

[0165] In one embodiment, the cooling fan is provided at the lower end of the side plate 216 and is arranged corresponding to the air flow exchange part 204.

The cooling fan is detachably assembled in the installation groove 207. In one embodiment, the installation groove 207 can be a sliding groove extending along the assembly direction of the battery pack, and the notch of the sliding groove is close to and opens downward towards the bottom plate. The cooling fan is fixed on an installation bracket 2032, and a guide rail 2033 is provided on the installation bracket 2032. From the bottom of the battery compartment 201 from bottom to top, the guide rail 2033 on the installation bracket 2032 is slidably connected to the installation groove 207, and the cooling fan can be assembled on the outer wall of the side plate 216 of the battery compartment 201.

[0167] In one embodiment, the present application further includes a first air hole provided on the battery pack. One of the first air hole and the second air hole is used for the battery pack to intake air from the outside, and the other is used for the battery pack to exhaust air to the outside, so that heat exchange can be carried out between the inside and the outside of the battery pack, thereby realizing the heat dissipation of the battery pack.

[0168] As Figures 3 to 8 and Figures 12 to 13 shown, in one embodiment, the present application further provides an outdoor working device, including: a battery compartment 201 having an opening, and an air flow exchange part 204 communicating the inside and the outside of the battery compartment 201 is provided on the battery compartment 201; a battery pack configured to be detachably assembled in the battery compartment 201, and a second air hole corresponding to the air flow exchange part 204 is provided on the battery pack; a heat dissipation fan at least configured to cool the battery pack, and the heat dissipation fan can blow air in a first direction; when the battery pack is assembled in the battery compartment 201, in the first direction, the projection of the air flow exchange part 204, the projection of the second air hole and the projection of the heat dissipation fan at least partially overlap. Such a setting enables the gas inside the battery pack to be directly exhausted to the outside or blown into the battery pack when dissipating heat from the battery pack, with a shorter air flow path and no need to bend, improving the heat dissipation efficiency of the battery pack.

[0169] As Figures 3 to 8 and Figures 12 to 13 shown, in one embodiment, an outdoor working device of the present application includes: a battery compartment 201 having an opening, and the battery compartment 201 further includes a bottom plate and a plurality of side plates 216 surrounding the bottom plate. An installation position 224 is provided on the inner wall of at least one side plate 216, and an installation groove 207 is provided on the outer wall; the battery pack is configured to be assembled from the upper end of the side plate 216 to the installation position 224; the heat dissipation fan is configured to be assembled from the lower end of the side plate 216 along the installation groove 207.

[0170] As Figures 9 to 11 , in one embodiment, the installation direction of the battery pack on the battery compartment 201 is opposite to the installation direction of the heat dissipation fan on the battery compartment 201. Specifically, as Figure 10 is the internal schematic diagram of the battery compartment 201, Figure 11 is the bottom schematic diagram of the battery compartment. In the up and down direction, the battery pack is assembled from top to bottom on the inner wall of the battery compartment 201, and the heat dissipation fan is assembled from bottom to top on the outer wall of the battery compartment 201.

[0171] As Figure 12 shown, in one embodiment, at least one side plate 216 is provided with an air flow exchange part 204 communicating the inside and the outside of the battery compartment 201. When the battery pack and the heat dissipation fan are assembled in place on the battery compartment 201, the blowing direction of the heat dissipation fan is the same as and on the same straight line as the air outlet direction of the air flow exchange part 204.

[0172] As shown Figure 13 In one embodiment, it further includes a first air hole and a second air hole provided on the battery pack. One of the first air hole and the second air hole is used for the battery pack to intake air inward, and the other is used for the battery pack to exhaust air outward.

[0173] As shown Figure 12 and Figure 13 In one embodiment, when the battery pack and the cooling fan are assembled in place on the battery compartment 201, one of the first air hole and the second air hole is in the same direction as the blowing direction of the cooling fan and on the same straight line.

[0174] In one embodiment, the blowing direction of the cooling fan is defined as the first direction. When the battery pack is assembled on the battery compartment 201, in the first direction, the projection of the air flow exchange part 204 overlaps at least partially with the projection of the first air hole and the projection of the cooling fan. In one embodiment, the ratio of the overlapping area of the projection of the air flow exchange part 204 and the projection of the first air hole is 20% - 40%. In a specific embodiment, the ratio of the overlapping area of the projection of the air flow exchange part 204 and the projection of the first air hole is 20%, 30% or 40%. In one embodiment, the ratio of the overlapping area of the projection of the air flow exchange part 204 and the projection of the cooling fan is 20% - 40%, and the ratio of the overlapping area of the projection of the air flow exchange part 204 and the projection of the cooling fan is 20%, 30% or 40%.

[0175] In one embodiment, the ratio of the area of the first air hole to the area of the air flow exchange part 204 is (0.5 - 2.0):1. In a specific embodiment, the ratio of the area of the first air hole to the area of the air flow exchange part 204 is 0.5:1, 0.6:1, 1.2:1 or 1.9:1.

[0176] In one embodiment, when the battery pack is the first type of battery pack 205, due to its relatively small capacitance, its heat dissipation requirement is relatively small, and the hole area of the first air hole is designed to be relatively small. The ratio of the area of the first air hole to the area of the air flow exchange part 204 is preferably 0.5:1 or 0.6:1. When the battery pack is the second type of battery pack 206, due to its relatively large capacitance, its heat dissipation requirement is relatively large, and the hole area of its first air hole is designed to be relatively large. The ratio of the first air hole to the area of the air flow exchange part 204 is preferably 1.2:1 or 1.9:1.

[0177] As shown Figures 9 to 11As shown, in one embodiment, in order to save installation space and material costs, the battery compartment 201 of the present application further includes an installation portion. At least part of the installation portion is configured as an installation position 224 inside the battery compartment 201, and at least part of the installation portion is configured as an installation groove 207 outside the battery compartment 201. The installation position 224 and the installation groove 207 are of an integral structure. One part of the installation portion is designed as the installation position 224 for installing the battery pack, and the other part is designed as the installation groove 207 for installing the cooling fan. This not only saves space and material costs, but also makes the installation distance between the cooling fan and the battery pack relatively close. The cooling fan can discharge the heat generated during the charging and discharging of the battery pack nearby, resulting in better heat dissipation effect.

[0178] In one embodiment, the cooling fan for battery pack cooling is only provided on a single side plate 216 of the battery compartment 201. In one embodiment, the cooling fan on the single side plate 216 can blow air into the battery compartment 201, or exhaust air outside, or part of it exhausts air outside the battery compartment 201 and part of it blows air into the battery compartment 201. In one embodiment, 3 or 6 cooling fans are provided on a single side plate 216 of the battery compartment 201, or other numbers of cooling fans can be set according to actual usage requirements.

[0182] 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.

The bottom of the battery compartment 201 is a plane. 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. Such a setting method of inclining the opening of the battery compartment 201 towards the rear of the outdoor working device is beneficial for the user to take and place the battery pack when the user replaces the battery pack in the battery compartment 201. The battery packs in this embodiment include the above-mentioned first type of battery pack 205 and second type of battery pack 206.

[0185] 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.

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. In the vertical direction, the distance between the hitch 104 and the axis of the rear traveling wheel 602 is 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 too high or too low hitch points.

The angle α5 between the connecting part 102 and the second bearing part 103 is 10° to 30°, and the angle α5 between the connecting part 102 and the second bearing part 103 is preferably 10°, 20°, and 30°.

[0190] Of course, the first bearing part 101 and the second bearing part 103 are horizontally arranged, and the connecting part 102 can be connected to the first bearing part 101 and the second bearing part 103 in a perpendicular relationship.

[0191] As Figure 20As shown, 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. The ratio of the lengths of the first bearing portion 101, the connecting portion 102, and the second bearing portion 103 is preferably L1:L2:L3 = 5:6:30, L1:L2:L3 = 6:8:35, and L1:L2:L3 = 8:10:40.

[0192] 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.

[0193] In another embodiment, when the height of the second bearing portion 103 is higher than the height 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.

[0194] As Figure 22 、 Figures 28 to 32 As 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 provided 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 cover the power management device 219. The protective cover 106 is provided 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.

[0195] As Figure 1 、 Figures 30 to 31, 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, it will cause accumulation and affect the heat dissipation effect of the power management device 219.

[0196] 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 that enters 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, it not only ensures the ventilation effect of the protective cover 106, but also can effectively use Bernoulli's principle to discharge the debris that enters 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.

[0197] As Figure 30 shown, in an embodiment, the angle α1 between the first inclined surface 107 and the horizontal direction is 40° to 85°, and the 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 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.

[0198] As Figure 31 , in an embodiment, the hole area of the first through hole 108 is 60mm 2 ~80mm 2 , the hole area of the first through hole 108 is preferably 60mm 2 , 70mm 2 and 80mm 2 .

[0199] As Figure 31, the hole area of the second through hole 110 is 3 to 50 times that of the first through hole 108, and the hole area of the second through hole 110 is 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.

[0200] Such as Figure 30 And Figure 31 , 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 enters the protective cover 106, so that the debris that enters the groove 115 can move towards the groove 115 as much as possible and reduce the movement towards the rear of the protective cover 106.

[0201] Such as Figure 30 , in an embodiment, the angle α2 between the second inclined surface 109 and the horizontal direction is 0° to 60°, and the angle α2 between the second inclined surface 109 and the horizontal direction is 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, which can minimize the movement of the debris towards the rear of the protective cover 106.

[0202] Please refer to Figure 30 And Figure 31, 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 air flow 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.

[0203] As Figure 30 and Figure 31 , 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 air flow at the first through-hole 108 is accelerated during the process of flowing to the second through-hole 110. During the process of the accelerated air flow flowing to 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.

[0204] In one embodiment, as Figure 32As 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 Bernoulli's effect (Bernoulli's effect means that in a fluid, if the velocity is small, the pressure is large; if the velocity is large, the pressure is small. Bernoulli's 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. This will generate a pressure towards the outside of the protective cover 106 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.

[0205] As Figure 30 and Figure 31 shown, 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 entering 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 contributing to the heat dissipation of the power management device 219 inside the protective cover 106.

[0206] As Figure 30 and Figure 31As shown, in one embodiment, in the vertical 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. In the case where 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 utilized to discharge the heavier debris and the like. In order to discharge the larger-volume debris, in one 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.

[0207] As Figure 31 , in one embodiment, the third through-hole 114 is designed to be a strip-shaped structure.

[0208] As Figure 31 , in one 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 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 damaging the power management device 219.

[0209] In one 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 some 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 face away from or be far from the power management device 219, so as to guide the liquid or hard objects entering the third through-holes 114 not to directly splash or hit the power management device 219, preventing damage.

[0210] As Figure 23 and Figures 28 to 31As 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 does not affect each other.

[0211] As Figure 23 and Figure 24 shown, in a specific embodiment, the power management fixing bracket 105 includes a connected fixing leg 1051 and a fixing plate 1052. The fixing leg 1051 is used to be fixed to the power supply fixing member 116, and 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 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.

[0212] Referring to Figures 5 to 8 、 Figure 23 and Figures 25 to 26 shown, 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. The power management device 219 is located below the battery compartment 201. In the front-rear direction of the outdoor working equipment, the power management device 219 is located between the two side plates 216. Such a setting enables the power management device 219 to be directly electrically connected to the electric connection terminals 220 on the two side plates 216 respectively through wire harnesses upward. Installing the power management device 219 between the two side plates 216 respectively provided with electric connection terminals 220 enables the power management device 219 to achieve 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.

[0213] Referring to Figures 5 to 8 and Figure 23As shown, in one embodiment, 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 terminals 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 terminals 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 wire harness connecting the electrical connection terminals 220 to the power management device 219 more reasonable, and the battery pack can be electrically connected to the power management device 219 through the electrical connection terminals 220.

[0214] Please also refer to Figures 5 to 8 , in one embodiment, an air flow generator 2031 (heat dissipation fan) is provided below each electrical connection terminal 220, and the air flow generator 2031 is also directly connected to the power management device 219 downward through a wire harness, saving the use of wire harnesses and raw material costs, and making the layout of the entire outdoor working device more reasonable.

[0215] Please also refer to Figure 28 , 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 to 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.

[0216] As Figures 5 to 8 and Figure 23 , further, 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. Horizontally, 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 wire harnesses respectively. Such a setting also reasonably saves the wire harness distance for connecting the power management device 219 and the heat dissipation fans.

[0217] As Figure 1 、Figure 23 , Figure 28 and Figure 31 As shown in Figure 23 , Figure 28 , and Figure 31 , in one embodiment, the lower surface of the power management device 219 is inclined towards the advancing direction of the outdoor working device. With such a setting, when the outdoor operation is advancing, the bottom surface of the power management device 219 can come into contact with more of the airflow entering through the first through-hole 108, increasing the contact area between the lower surface of the power management device 219 and the airflow, and improving the heat dissipation effect of the power management device 219.

[0218] 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.

[0219] As Figure 1 and Figure 22 and Figure 28 As shown in Figure 1 , Figure 22 , and Figure 28 , in one embodiment, an outdoor working device of the present application includes a vehicle frame 100; a power supply device 200 is provided on the vehicle frame 100, at least for supplying power to the outdoor working device; a power management device 219 is fixed below the vehicle frame 100 and is used to control the charging or discharging of the power supply device 200; a protective cover 106 is provided 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 protective space that surrounds the power management device 219 to protect the power management device 219 from being damaged by external liquids or solids.

[0220] As Figure 31 , two connected protrusion parts 113 protrude from the bottom of the protective cover 106 towards the inside of the protective cover 106. The setting of the protrusion parts 113 can strengthen the strength of the protective cover 106. Secondly, the setting of the protrusion parts 113 also makes the extra space inside the protective cover 106 smaller. Moreover, the protrusion parts 113 are located between the second through-hole 110 and the third through-hole 114, so that the debris entering the protective cover 106 can be discharged from the third through-hole 114 under the delivery action of the protrusion parts 113, preventing the debris from accumulating inside the protective cover 106.

[0221] As Figure 1 , Figure 33 and Figure 35As shown, in one embodiment, the present application includes: a frame 100, on which are provided: a traveling assembly 600 configured to support the outdoor working equipment to travel; a power output assembly 500 configured to perform outdoor operations; a seat 400 configured for a user to sit on; a power supply device 200 configured to supply power to the outdoor working equipment with a tail cover 210; the tail cover 210 is disposed on the power supply device 200, and at least a reverse radar 213 is provided on the tail cover 210: the reverse radar 213 is used to monitor the rear area when the outdoor working equipment is traveling in reverse; a tail light 214, and the tail light 214 at least displays the operating state of the outdoor working equipment with the tail cover 210.

[0222] As Figure 35 , in one embodiment, the tail cover 210 includes a main board 2101 located at the rear of the outdoor working equipment and auxiliary boards 2102 located on both sides of the outdoor working equipment and connected to the main board 2101; the power supply device 200 includes a battery compartment 201 for installing a battery pack, and 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 of the entire outdoor working equipment beautiful and simple.

[0223] As Figure 35 As shown, in one embodiment, the tail light 214 includes a main light portion 2141 located on the main board 2101 and auxiliary light portions 2142 extending from both ends of the main light portion 2141 to the auxiliary boards 2102; when the user is located on the side or rear of the outdoor working equipment, the state of the tail light 214 can be observed. Such an arrangement is conducive to the user directly observing the flashing of the tail light 214 at multiple positions, and helps the user understand whether the battery pack and the battery compartment 201 are properly installed.

[0224] As Figure 36 As 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 an accommodation space 211 is formed between the tail cover 210 and the battery compartment 201. The reverse radar 213 is located in the accommodation space 211, which plays a protective role for the reverse radar 213.

[0225] As Figure 25 , in one embodiment, a radar controller 2235 electrically connected to the reverse radar 213 is further provided outside the battery compartment 201, and the radar controller 2235 is used to receive and process the signal of the reverse radar 213.

[0226] In one embodiment, a power management device 219 is disposed below the power supply device 200. A taillight 214 and a radar controller 2235 are disposed on the power supply device 200. The taillight 214 and the radar controller 2235 are also directly connected to the power management device 219 below them through a wiring harness, and obtain electric energy and relevant instruction information through the power management device 219.

[0227] As Figure 36 shown, in one embodiment, a cooling fan for cooling the battery pack is disposed on a side plate 216 of the battery compartment 201. An accommodation space 211 is formed between the tail cover 210 and the battery compartment 201. The cooling fan and the wiring harness connecting the cooling fan are located in the accommodation space 211. Such an arrangement can protect the cooling fan and its wiring harness from being contaminated by sundries while ensuring that there is space for the cooling fan to circulate air.

[0228] As Figure 21 and Figure 36 shown, in one embodiment, a battery pack is installed inside the battery compartment 201. A charging connector 218 is further disposed on the outer wall of the battery compartment 201. A power management device 219 is disposed below the battery compartment 201. By installing the charging connector 218 on the battery compartment 201, the charging connector 218 is electrically connected to the power management device 219 below through a wiring harness. The power management device 219 is electrically connected to the battery pack through an electrical connection terminal 220 on the battery compartment 201. When the charging connector 218 is connected to a charging gun, the power management device 219 can charge the battery pack through the electrical connection terminal 220 on the battery compartment 201. Such an arrangement also optimizes the wiring harness layout.

[0229] As Figure 21 shown, in one embodiment, the charging connector 218 is disposed 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°. The designs of the 45° angle and the 60° angle help users to plug and unplug the charging gun from the charging connector 218.

[0230] Referring also to Figure 21 、 Figure 24 and Figure 35 shown, in one embodiment, a mounting seat 223 for installing the charging connector 218 is disposed on the battery compartment 201. The tail cover 210 is mounted on the mounting seat 223. A charging avoidance opening 212 for the charging connector 218 to expose is disposed on the tail cover 210. The charging connector 218 passes through the charging avoidance opening 212 of the tail cover 210 to be connected to the charging gun.

[0231] Please also refer to Figure 24, in one embodiment, the mounting base 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 plate 2181 is provided on the charging connector 218, and the charging connector 218 is provided on both sides of the fitting plate 2181. During installation, one end of the charging connector 218 passes through the perforation, so that the fitting 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.

[0232] Please also refer to Figure 24 , in one embodiment, the included 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 the user to plug and unplug the charging gun.

[0233] As Figure 24 shown, further, the mounting base 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 below the mounting surface 2231, so that while supporting the mounting surface 2231, the occupied space is small.

[0234] In one embodiment, the mounting base 223 is provided corresponding to a temperature control component 203. In order not to affect the air exhaust or air 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, which is beneficial to the temperature control component for air exhaust or air intake.

[0235] As Figure 24 shown, in one embodiment, a connecting portion 2233 is further provided below the second panel 2238, and the connecting portion 2233 is used to connect with the power supply fixing member 116, so that the installation of the mounting base 223 is more firm.

[0236] As Figure 24 shown, in one embodiment, a connecting sub-panel 2234 is provided on the side surface of the mounting base 223, and a radar controller 2235 is provided on the connecting sub-panel 2234, and the radar controller 2235 is electrically connected to the reverse radar 213.

[0237] As Figure 24As shown, in one embodiment, mounting holes 2236 are further provided on the mounting surface 2231, and corresponding openings matching the mounting holes 2236 are also provided on the tail cover 214. By fastening bolts to the openings and the mounting holes 2236, the tail cover 214 can be fixed to the mounting seat 223, playing a role in installing and fixing the tail cover 214.

[0238] As Figure 24 shown, in one embodiment, the taillight 214 is provided above the tail cover 210. A charging connector 218 is provided below the taillight 214, and the charging connector 218 is provided at the middle position of the tail cover 210. The reverse radar 213 is provided on both sides of the charging connector 218 and is arranged substantially flush with the reverse radar 213.

[0239] In one embodiment, the reverse radar 213 can be directly installed on the battery compartment 201, or the reverse radar 213 can be installed on the vehicle frame 100. Of course, the reverse radar 213 can also be installed on the seat 400, and corresponding selection and design can be made according to actual usage requirements.

[0240] As Figure 33 and Figure 34 shown, according to the ergonomic analysis, in the horizontal direction, with the direction in which the vehicle frame 100 extends 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 (the S3 area) is the visible blurred area.

[0241] Because 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 120° double-view clear area 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° (the S4 area), and there is a 60° included angle visual blind area (the S2 area) directly behind the vehicle.

[0242] As Figure 33 and Figure 34As shown, 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 user can at least cover a visual field range of 300° in the horizontal direction in front of and on both sides of the outdoor working equipment; a detection assembly, which is arranged at the rear of the outdoor working equipment, and the detection assembly detects at least a range of 60° in the horizontal direction. Among them, the visual field range of the user and the detection range of the detection assembly can completely cover the four sides of the outdoor working equipment in the horizontal direction.

[0243] As Figure 34 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. Preferably, the length of the spatial area (S6) at least detected by the detection assembly is 1.4 m, 1.5 m, and 1.6 m, the width is 1.5 m, 1.6 m, and 1.7 m, and the height is: 1.1 m, 1.2 m, and 1.3 m.

[0244] As Figure 33 , in one embodiment, the distance A between the spatial area (S6) and the outdoor working equipment is greater than or equal to 100 mm and less than or equal to 250 mm. The distance A between the spatial area (S6) and the outdoor working equipment is preferably 100 mm, 180 mm, and 250 mm.

[0245] As Figure 33 , in one embodiment, the distance B between the spatial area (S6) and the working surface is greater than or equal to 100 mm and less than or equal to 200 mm. The distance B between the spatial area (S6) and the working surface is preferably 100 mm, 150 mm, and 200 mm.

[0246] As Figure 35 , in one embodiment, preferably, the detection assembly includes a reverse radar 213, and two reverse radars 213 are arranged on each side of the center line. The distance between the two reverse radars 213 is 350 mm to 400 mm, preferably 360 mm.

[0247] As Figure 1 and Figure 33, in one embodiment, the height of the reverse radar 213 from the ground is 320 mm to 360 mm, and the preferred heights of the reverse radar 213 from the ground are 320 mm, 340 mm, and 360 mm. Such height settings can cover children and small animals with relatively low heights to prevent accidental injuries.

[0248] It should be understood that a radar controller 2235 for controlling the reverse radar 213 is also provided on the battery compartment 201. The radar controller 2235 is used to receive the signal of the reverse radar 213 and then connect to the vehicle control module through the CAN communication signal, and can transmit instructions to control the vehicle alarm system (alarm sound) to prompt the driver to pay attention to avoid collision events.

[0249] The radar controller 2235 can also be connected to the vehicle control module through the power management device 219.

[0250] As Figures 37 to 39 shown, in one embodiment, the outdoor working device includes a frame 100, and the frame 100 is provided with: a traveling assembly 600 for supporting the outdoor working device to travel; a power output assembly 500 for performing outdoor work; a seat 400 for the user to sit on; a power supply device 200 for supplying power to the outdoor working device; and a storage box 700 located between the seat 400 and the power supply device 200. Setting the storage box 700 between the seat 400 and the power supply device 200 can utilize the extra space between the seat 400 and the power supply device 200, and the storage box 700 is located beside the seat 400, enabling the user to conveniently obtain tools or other items in the storage box 700 when using the outdoor working device.

[0251] As shown in Figure 38 and Figure 39 , in one embodiment, the storage box 700 is provided at one end close to the power supply device 200, and each of the two sides of the storage box 700 is provided with an extension plate 701. The extension plates 701 on both sides overlap with the power supply device 200 to form an accommodation cavity 209. Since a heat dissipation fan is provided on the battery compartment 201 of the present application, the accommodation cavity 209 is provided to form a ventilation channel for discharging the heat of the battery pack in the battery compartment 201 to facilitate heat dissipation, and the wire harness connected to the heat dissipation fan can also be accommodated in the accommodation cavity 209 to protect the heat dissipation fan and the wire harness.

[0252] As Figure 37 , in a specific embodiment, the power supply device 200 includes a battery compartment 201, and a plurality of reinforcing ribs 215 are provided on the battery compartment 201. The two extension plates 701 respectively overlap with the reinforcing ribs 215. Specifically, the reinforcing ribs 215 are provided on the outer wall of the battery compartment 201, and one extension plate 701 overlaps with one reinforcing rib 215.

[0253] As Figure 37 , in one embodiment, the seat 400 includes a seat cushion portion 401 and a backrest portion 402. A slide rail is disposed between the vehicle frame 100 and the seat 400 and is arranged in the front - rear direction of the vehicle frame 100. The seat 400 can move in the front - rear direction of the vehicle frame 100 on the slide rail. When the seat 400 moves to the rearmost position of the slide rail, at least a part of the backrest portion 402 is located directly above the storage box 700. Such a setting can play a certain role in covering the items placed in the storage box 700 and reduce the situation where items fall out of the storage box 700 due to the running bumps of the vehicle.

[0254] As Figure 37 , in one embodiment, in the up - down direction, the storage box 700 is located below the seat 400, which can avoid interference with the front - rear adjustment of the seat 400 caused by the storage box 700.

[0255] In one embodiment, a box cover is provided at the opening of the storage box 700 to prevent sundries from falling into the interior of the storage box 700 and prevent damage or contamination to the items in the storage box 700.

[0256] As Figure 37 , in one embodiment, the storage box 700 is detachably mounted on the vehicle frame 100, and there will be no interference when disassembling or assembling the seat 400 or the power supply device 200.

[0257] Of course, the storage box 700 can also be configured to install a battery pack to supply power to the outdoor working equipment. When it is necessary to increase the endurance of the outdoor working equipment to increase the working area, the storage box 700 in the present application can also be used to install a battery pack. The battery pack is connected to the power management device 219 through a wire harness and is controlled by the power management device 219 for charging and discharging. Of course, the battery pack installed in the storage box 700 can also be used as a backup power source. When the power in the battery compartment 201 is exhausted or about to be exhausted, the battery pack in the storage box 700 supplies power to the outdoor working equipment to support the outdoor working equipment to return to the working position or continue outdoor work. Of course, the battery pack in the storage box 700 can also supply power to the above - mentioned temperature - regulating component 203 to reduce the power supply pressure of the first - type battery pack 205 or the second - type battery pack 206.

[0258] In one embodiment, the volume of the storage box 700 is 3L - 20L. The preferred volumes of the storage box 700 are 3L, 6.6L, and 20L.

[0259] As Figure 39, in one embodiment, a charging port is provided on the storage box 700. The charging port 702 can be electrically connected to the battery pack in the battery compartment 201 or the battery pack provided in the storage box 700. The charging port 702 can charge 3C products, such as mobile phones, music players, etc., and can also supply power to other gardening tools.
