Description

[Technical field]

[0001] The present application relates to the technical field of outdoor equipment, and in particular to outdoor working equipment. [Background Technology]

[0002] Many outdoor equipment, especially outdoor garden mowers, lack protective panels on their power management units (PMUs). These units are typically installed in locations where water cannot penetrate, relying on the unit's inherent sealing to prevent water from entering. High-pressure water jets can cause splashing even in locations where water cannot penetrate. Over time, the PMU's seals degrade and become less effective, putting the unit at risk of water intrusion. While some PMUs utilize protective panels, these do not optimize heat dissipation and can even cause dust accumulation, compromising heat dissipation and impacting the unit's performance and lifespan.

[0003] In view of this, it is indeed necessary to provide an improved outdoor working equipment to overcome the defects of the prior art. [Utility Model Content]

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide an outdoor working equipment that can reduce the friction between the sealing gasket and the dust collecting body and increase the service life of the sealing gasket.

[0005] The technical solution adopted by this application to solve the existing technical problems is: an outdoor working equipment, comprising:

[0006] Frame; the frame is provided with:

[0007] A walking assembly, configured to support the outdoor working equipment in walking;

[0008] a cutting assembly configured to perform the outdoor operation; a power supply device at least for supplying power to the outdoor operation equipment;

[0009] a power management device, disposed below the power supply device, the power management device being at least used to control charging or discharging of the power supply device;

[0010] The protective cover is at least used to protect the power management device. The protective cover is arranged below the power management device and is provided with a first through hole and a second through hole at least for heat dissipation.

[0011] A further improved solution is: the lower surface of the protective cover includes a first inclined surface arranged obliquely along the forward direction of the outdoor working equipment, and the first through hole and the second through hole are respectively arranged at the upper end and the lower end of the first inclined surface;

[0012] When the outdoor working equipment moves forward, outside the protective cover, the speed of the airflow through the first through hole is lower than the speed of the airflow through the second through hole, wherein at least part of the debris entering the protective cover through the first through hole can flow out from the second through hole under the action of negative pressure.

[0013] A further improvement is that: a third through hole is further provided on the protective cover;

[0014] When the outdoor working equipment moves forward, outside the protective cover, the airflow through the second through hole has a lower speed than that through the third through hole, wherein at least part of the debris within the protective cover can flow out of the third through hole under the action of negative pressure.

[0015] A further improvement is that the protective cover is arranged at an angle, and the lower surface of the protective cover is inclined toward the forward direction of the outdoor working equipment.

[0016] A further improvement is that, in the up and down directions, the height of the lowest end of the first through hole, the height of the lowest end of the second through hole, and the height of the lowest end of the third through hole decrease in sequence.

[0017] A further improvement scheme is: a power supply fixing plate is provided on the frame, the power supply device includes a battery compartment for installing a battery pack, the battery compartment is fixed above the power supply fixing plate, a power supply management fixing frame is provided below the power supply fixing plate, and the power supply management device is provided on the power supply management fixing frame.

[0018] A further improvement scheme is: the battery compartment includes two side panels arranged correspondingly, and the two side panels are respectively provided with electrical connection terminals connected to the battery pack. In the horizontal direction, the power management device is located between the two side panels and the power management device can be electrically connected to the electrolytic connection terminals on the two side panels through wiring harnesses.

[0019] A further improvement scheme is: the battery compartment includes two side panels arranged correspondingly, and the two side panels are respectively provided with a cooling fan for dissipating heat from the battery pack. In the horizontal direction, the power management device is located between the two side panels and the power management device can be electrically connected to the cooling fans on the two side panels through wiring harnesses.

[0020] The present application also provides an outdoor working equipment, comprising:

[0021] The frame is provided with: a power supply device, at least for supplying power to the outdoor working equipment; a power management device, fixed below the frame, for controlling the charging or discharging of the power supply device; a protective cover, provided below the power management device; wherein the bottom of the power supply device, the frame and the protective cover form a protective space surrounding the power management device.

[0022] A further improvement is that: along the front-to-back direction of the frame, the protective cover is provided with a first through hole, a second through hole and a third through hole at least for dissipating heat for the power management device at intervals.

[0023] Compared with the prior art, this application has the following beneficial effects:

[0024] In this application, when the outdoor work equipment is moving forward, the airflow through the first through-hole outside the protective cover is slower than the airflow through the second through-hole. At least some of the debris that enters the protective cover through the first through-hole is able to flow out through the second through-hole under the action of negative pressure. This ensures ventilation of the protective cover while utilizing the Bernoulli principle to effectively expel debris that enters the protective cover through the first through-hole through the second through-hole.

[0025] In order to discharge the debris that is not discharged from the second through hole and moves to the rear of the protective shell, the rear part of the protective cover of the present application is also configured as a third inclined surface connected to the second inclined surface and inclined along the forward direction of the outdoor work equipment, and the protective cover is provided with a third through hole at the lower end of the third inclined surface; when the outdoor work equipment moves forward, outside the protective cover, the speed of the airflow through the second through hole is lower than the speed of the airflow through the third through hole, wherein at least part of the debris located in the protective cover can flow out from the third through hole under the action of negative pressure. This helps to discharge the debris that is not discharged from the second through hole from the third through hole. In this way, through the secondary negative pressure chip removal treatment, the debris that enters the protective shell can be effectively discharged from the protective shell again, and the ventilation effect of the protective shell is also guaranteed;

[0026] The recess is arranged on the outer side of the rear part of the power management device, and the third through hole is set to face away from or away from the power management device to guide the liquid or hard objects entering the third through hole to prevent them from splashing or collapsing directly onto the power management device to prevent damage.

[0060] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0061] See also Figures 1 to 31 The figure shows an outdoor working equipment according to an embodiment of the present application. Specifically, the outdoor working equipment includes a frame 100 , a power supply device 200 , an operating assembly 300 , a seat 400 , a power output assembly 500 and a travel assembly 600 .

[0062] The frame 100 extends in one direction, and the power supply unit 200 is arranged at the rear of the frame 100. The power supply unit 200 includes a battery pack, a power management device 219 that controls the output and input of the battery pack, and a battery compartment 201 for mounting the battery pack. The battery pack is electrically connected to the electrical connection terminals 220 on the battery compartment 201 via the power terminals on the battery pack to power the outdoor work equipment. The battery pack includes a first type battery pack 205 and a second type battery pack 206. Preferably, the battery compartment 201 can be configured to accommodate first type battery packs 205 and second type battery packs 206 of different capacities or sizes to increase the adaptability of the outdoor work equipment to different battery packs. The battery pack can also be removed to power other power tools, increasing the battery pack's versatility. Compared to the traditional use of fossil fuels as an energy source, the outdoor work equipment of the present application is more environmentally friendly and more in line with long-term development plans. Preferably, the battery pack is a lithium iron phosphate battery pack or a ternary lithium battery pack.

[0063] In one embodiment, the first type battery pack includes a ternary lithium battery pack, and the second type battery pack includes a lithium iron phosphate battery pack.

[0064] The operating assembly 300 includes a left operating lever and a right operating lever disposed on the left and right sides of the outdoor working equipment. The user manipulates the left operating lever and the right operating lever to control the outdoor working equipment to move forward, backward, or turn. The operating assembly 300 can also be a steering wheel capable of controlling the outdoor working equipment.

[0065] In one embodiment, the operating assembly 300 is provided with control buttons for adjusting the operating speed of the power output assembly 500 and the travel assembly 600, thereby facilitating the user to quickly and accurately control the operation of the outdoor work equipment. Furthermore, the operating assembly 300 may also be provided with a button for adjusting the brightness of the outdoor work equipment's headlights.

[0066] The seat 400 is set on the frame 100, and the left and right operating levers are set close to the seat 400 and located on the left and right sides of the seat 400, so that a user sitting on the seat 400 can operate the left and right operating levers to control the operation of the outdoor working equipment.

[0067] The power output assembly 500 is used to implement the tool's function. In one embodiment, the outdoor work equipment is a riding lawn mower. The power output assembly 500 is specifically a cutting assembly and is disposed below the vehicle frame 100. It is used to output power to enable the riding lawn mower to mow. The cutting assembly is provided in two or three groups.

[0068] In one embodiment, the cutting assembly includes: a cutter disc, a mowing element, and a cutting motor. The cutting motor is controlled by a control button on the operating assembly 300, and the mowing element is used to cut vegetation such as grass when rotating at high speed. For example, the mowing element is a blade used to cut vegetation on a lawn. The cutter disc is formed with 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. 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.

[0069] Of course, the power output assembly 500 can also be removed from the outdoor work equipment. In some embodiments, it is understood that the power output assembly 500 can be replaced with other components to meet the needs of different gardening operations. Therefore, the outdoor garden mower can not only cut vegetation, but the cutting assembly can also be replaced with functional components such as snow shoveling, snow sweeping, snow blowing, and snow flushing. Those skilled in the art should be able to adaptably replace various functional components without inventive work, and all of these should be included in the scope of protection of this embodiment.

[0070] When the cutting component is replaced with functional components such as snow shoveling, snow sweeping, and snow blowing, the power supply device 200 of the outdoor work equipment of the present application can also adapt to relatively cold environments to provide power for the above-mentioned functional components such as snow shoveling, snow sweeping, and snow blowing.

[0071] The travel assembly 600 includes travel wheels mounted on the frame 100 and a travel motor for driving the travel wheels. The travel wheels are located on both sides of the frame 100 to maintain the center of gravity of the outdoor work equipment within the frame 100, thereby reducing the chance of the outdoor work equipment tipping over while traveling.

[0072] In one embodiment, the number of running wheels is set to four, including two front running wheels 601 and two rear running wheels 602. The front running wheels 601 can be universal wheels, and the running motor is connected to the rear running wheels 602 and drives the rear running wheels 602 to rotate. The two rear running wheels 602 are both equipped with running motors, and the speeds of the two running motors can be the same or different. When the user drives the outdoor work equipment straight, the speeds of the two running motors are roughly the same; when the user drives the outdoor work equipment to turn, the speeds of the two running motors are different, and the outdoor work equipment turns to the side with the lower running motor speed. In some embodiments, the diameter of the front running wheel 601 is smaller than the diameter of the rear running wheel 602.

[0073] In one embodiment, please also refer to Figure 2 、 Figure 3 and Figure 4 The power supply device 200 is used to power at least outdoor working equipment. The power supply device 200 includes a battery compartment 201. The battery compartment 201 can be installed with a first-type battery pack 205 or a second-type battery pack 206, or both. The first-type battery pack 205 and the second-type battery pack 206 can be installed in the battery compartment 201 in a detachable manner.

[0074] The first type battery pack 205 and the second type battery pack 206 can also be removed from the battery compartment 201 to power other tools.

[0075] See Figure 2 、 Figure 3 and Figure 4 , multiple temperature control components 203 are also provided on the battery compartment 201. The multiple temperature control components 203 perform temperature control operations by obtaining electrical energy from the battery packs on the outdoor working equipment. The multiple temperature control components 203 are configured to be able to control the temperature of the first type battery pack 205 and / or the second type battery pack 206.

[0076] Of course, the energy of the multiple temperature control components 203 can be obtained from the first type battery pack 205 or the second type battery pack 206 in the battery compartment 201, or other battery packs that can provide energy on the outdoor working equipment.

[0077] See Figure 2 、 Figure 3 and Figure 4 Specifically, when the first type battery pack 205 and the second type battery pack 206 need to be cooled, the temperature control component 203 is an airflow generator 2031 that can generate airflow, which can be a cooling fan, for cooling the first type battery pack 205 and the second type battery pack 206.

[0078] When the first type battery pack 205 and the second type battery pack 206 need to be heated, the temperature control component 203 is an airflow generator 2031 capable of generating airflow and a heater capable of generating heat. The airflow generator 2031 is used to blow the heat generated by the heater to the first type battery pack 205 and the second type battery pack 206 for heating.

[0079] like Figure 2 In one embodiment, when the number of first-type battery packs 205 loaded into the battery compartment 201 is x, the number of temperature control components 203 configured to adjust the temperature for the first-type battery packs 205 is x. Specifically, the number of temperature control components 203 configured to perform temperature control for x first-type battery packs 205 at any time is x.

[0080] In one embodiment, when the internal temperatures of m of the x first-type battery packs 205 are higher than the normal range value but within the first range value, the power management device 219 will activate the m temperature control components 203 to perform temperature control on the m first-type battery packs 205 whose internal temperatures are within the first range value until the temperatures are adjusted to the normal range value.

[0081] The one-to-one matching of the number of first-type battery packs 205 and the number of temperature control components 203 is set to meet the requirement that although the temperature of the first-type battery pack 205 during charging and discharging is different from the temperature within the normal range, under limited temperature control requirements, one temperature control component 203 can meet the heat dissipation or heating requirements of the first-type battery pack 205, and the first-type battery pack 205 does not need to be temperature-controlled when the temperature is within the normal range. Since the energy source of the temperature control component 203 also comes from the battery pack, the battery pack's electrical energy can be saved and the battery pack's endurance can be improved.

[0082] Furthermore, the temperature range of the first range value can be higher 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 control component 203 only activates the airflow generator 2031 to dissipate heat from the first type battery pack 205, so that the temperature within the first type battery pack 205 is quickly reduced to within the normal range value, thereby facilitating 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 control component 203 activates the airflow generator 2031 and the heater. The airflow generator 2031 blows the heat generated by the heater toward the first type battery pack 205, thereby raising the temperature of the first type battery pack 205 to the normal range value, thereby facilitating the charging or discharging of the battery pack.

[0083] It should be understood that the heater (not shown in the figure) can be a heating wire or other component that can generate heat, and the heater is set corresponding to the air outlet of the air flow generator 2031.

[0084] In one embodiment, when a one-to-one heat dissipation approach cannot meet the temperature control requirements of the first type battery pack 205, that is, when the number of first type battery packs 205 with internal temperatures within the second range is m, the number of temperature control components 203 configured to control the temperature of m first type battery packs 205 is at least m+1 and at most all temperature control components 203 in the outdoor work equipment. Specifically, the power management device 219 adjusts the operation of the temperature control components 203 based on the temperature within the first type battery pack 205. When the temperature within the first type battery pack 205 is within the second range, the power management device 219 simultaneously activates multiple temperature control components 203 to control the temperature of the first type battery pack 205, thereby ensuring normal charging and discharging of the first type battery pack 205.

[0085] It should be understood that when the temperature inside the first type battery pack 205 or the second type battery pack 206 is in the first range value and higher than the normal range value, and the second range value is higher than the first range value, the first type battery pack 205 or the second type battery pack 206 needs to be heat-dissipated; when the temperature inside the first type battery pack 205 or the second type battery pack 206 is in the first range value and lower than the normal range value, and the second range value is lower than the first range value, the first type battery pack 205 or the second type battery pack 206 needs to be heated.

[0086] In a preferred embodiment, the capacity of the first type battery pack 205 is greater than or equal to 90Wh and less than 1000Wh. The capacity of the first type battery pack 205 is preferably 90Wh, 600Wh or 999Wh.

[0087] like Figure 3 In one embodiment, when the number of second-type battery packs 206 loaded into the battery compartment 201 is y, the number of temperature control assemblies 203 configured to control the temperature of the second-type battery packs 206 is 2y. This one-to-two matching of the number of second-type battery packs 206 and the number of temperature control assemblies 203 is designed when one temperature control assembly 203 cannot meet the heat dissipation or temperature increase requirements of one second-type battery pack 206.

[0088] In a specific embodiment, the second type battery pack 206 has a larger capacity. The capacity of the second type battery pack 206 is generally greater than or equal to 1000Wh and less than or equal to 4000Wh. The capacity of the second type battery pack 206 is preferably 1000Wh, 2500Wh and 4000Wh.

[0089] In one embodiment, when the number of y second-type battery packs 206 installed in the battery compartment 201 whose internal temperatures are within the first range is n, the power management device 219 will activate 2n temperature control components 203 to perform temperature control on the n second-type battery packs 206 whose internal temperatures are within the first range.

[0090] The number of second-type battery packs 206 and the number of temperature control components 203 are set to a one-to-two matching manner in this way. This is to meet the situation where the second-type battery pack 206 generates heat during charging and discharging and one temperature control component 203 cannot meet the heat, so two temperature control components 203 are required to meet the heat dissipation or heating requirements of one second-type battery pack 206. When the temperature is within the normal range, the second-type battery pack 206 does not undergo temperature control. Since the energy source of the temperature control component 203 also comes from the battery pack, when the temperature control requirements are met, the fewer the temperature control components 203 that are started, the more the battery pack's electricity can be saved, thereby improving the battery pack's endurance.

[0091] In one embodiment, when the number of y second-type battery packs 206 loaded into the battery compartment 201 whose internal temperatures are within the second range of values ​​is n, the power management device 219 will activate at least 2n+1 temperature control components 203 to perform temperature control on the n second-type battery packs 206 whose internal temperatures are within the second range of values, and at most all the temperature control components 203 on the outdoor working equipment will perform temperature control on the n second-type battery packs 206 whose internal temperatures are within the second range of values.

[0092] like Figures 2 to 13 and Figure 18 In one embodiment, the battery compartment 201 includes two side panels 216 arranged opposite to each other, each side panel 216 is provided with a temperature control component 203, and the temperature control component 203 on one of the side panels 216 is arranged in a one-to-one correspondence with the temperature control component 203 on the other side panel 216. An electrical connection terminal 220 is provided on the battery compartment 201 near each temperature control component 203, and multiple electrical connection terminals 220 are respectively provided on two opposite side panels 216; a first type battery pack 205 is provided with a power terminal 2051, and when the first type battery pack 205 is loaded into the battery compartment 201, one power terminal 2051 is connected to one power connection terminal 220; two ends of the second type battery pack 206 are provided with two power terminals 2061, and when the second type battery pack 206 is loaded into the battery compartment 201, one of the two power terminals 2061 is connected to an electrical connection terminal 220 on one of the side panels 216, and the other of the two power terminals 2061 is connected to the electrical connection terminal 220 on the other side panel 216. The first type battery pack 205 supplies power to the outdoor working equipment through one power terminal 2051, and the second type battery pack 206 supplies power to the outdoor working equipment through two power terminals 2061.

[0093] like Figure 5 and Figure 18 As shown, in one embodiment, the battery compartment 201 includes two side panels 216 arranged opposite to each other, and each side panel 216 is provided with a plurality of mounting positions 224. The mounting positions 224 on one side panel 216 are arranged in a one-to-one correspondence with the mounting positions 224 on the other side panel 216. The two mounting positions 224 arranged in a one-to-one correspondence are a pair, and at least one pair of mounting positions 224 is staggered with the other mounting positions 224. The staggered setting of the mounting positions 224 helps to enhance the structural strength of the battery compartment 201.

[0094] In one embodiment, the offset distance between the offset mounting position 224 and other mounting positions 224 is 20 mm to 40 mm, and preferably the offset distance is 20 mm, 30 mm, and 40 mm.

[0095] Furthermore, each installation position is provided with an electrical connection terminal 220 , so that at least one pair of electrical connection terminals 220 is staggered with other electrical connection terminals 220 .

[0096] like Figure 5 and Figure 18 In a specific embodiment, three airflow exchange parts 204 are respectively provided on the two corresponding side panels 216 of the battery compartment 201. Three airflow exchange parts 204 are provided on one side panel 216, and a total of six airflow exchange parts 204 are provided on the two side panels 216. A temperature control component 203 is provided for each airflow exchange part 204, so six temperature control components 203 are also provided. Correspondingly, six electrical connection terminals 220 are also provided on the two side panels 216 on the battery compartment 201, three on one side panel 216 and three on the other side panel 216, and each electrical connection terminal 220 is provided in the upper area of ​​the airflow exchange part 204.

[0097] In one embodiment, the airflow exchange portion 204 is disposed on the mounting position 224 .

[0098] like Figures 2 to 4 The battery compartment 201 has an open opening for inserting and removing the first type battery pack 205 and the second type battery pack 206. A compartment cover 202 is provided corresponding to the opening. The compartment cover 202 is used to cover the opening of the battery compartment 201, forming a relatively closed cavity for the battery compartment 201. This prevents debris from entering the battery compartment 201 and ensures the normal operation of the first type battery pack 205 or the second type battery pack 206.

[0099] like Figures 5 to 8As shown, a plurality of airflow exchange parts 204 are provided on the two corresponding side panels 216 of the battery compartment 201, and one temperature regulating component 203 is matched with one airflow exchange part 204. The temperature regulating component 203 can exhaust and intake air into the battery compartment 201 through the corresponding airflow exchange part 204.

[0100] like Figures 5 to 8 As shown, in one embodiment, when the internal temperature of the first type battery pack 205 is within a first range value, the temperature control component 203 can blow air to the first type battery pack 205 loaded into the battery compartment 201 through the airflow exchange part 204, or exhaust air to the outside through the airflow exchange part 204 corresponding to the first type battery pack 205.

[0101] like Figures 5 to 8 As shown, further, when the temperature inside the first type 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 for the first type battery pack 205. The multiple temperature control components 203 can blow air into the battery compartment 201 at the same time; can also exhaust air out of the battery compartment 201 at the same time; can also partially blow air into the battery compartment 201 and partially exhaust air out of the battery compartment 201.

[0102] like Figure 3 and Figures 5 to 8 In one embodiment, when the internal temperature of the second type battery pack 206 is within the first range of values, the two temperature control assemblies 203 can simultaneously blow air or exhaust air, or one blows air and the other exhausts air, to the second type battery pack 206 loaded into the battery compartment 201 through the airflow exchange portion 204. Preferably, the two temperature control assemblies 203 are respectively disposed on two corresponding side panels 216 of the battery compartment 201, and the power terminals 2061 at both ends of the second type battery pack 206 are respectively connected to their corresponding two electrical connection terminals 220 located on the battery compartment 201. The two temperature control assemblies 203 are located near the electrical connection terminals 220 on the two side panels 216. Therefore, the temperature control assemblies 203 can also dissipate heat generated by the contact between the electrical connection terminals 220 and the power terminals 2061.

[0103] Furthermore, when the internal temperature of the second type battery pack 206 is within the second range, the multiple temperature control components 203 can simultaneously blow air or exhaust air or at least one blow and at least one exhaust air to the second type battery pack 206 loaded into the battery compartment 201 through the airflow exchange unit 204.

[0104] Please also see Figures 5 to 8 、 Figure 10 and Figure 11To improve heat dissipation or temperature increase, in one embodiment, the first type battery pack 205 is provided with a first vent 2052 or a second vent 2053, with one of the first vent 2052 and the second vent 2053 aligning with the airflow direction of the airflow generator 2031. With this arrangement, when the temperature control assembly 203 is temperature-controlling the first type battery pack 205 or the second type battery pack 206, heat within the first type battery pack 205 can be removed through the first vent 2052 or the second vent 2053, allowing the heat within the first type battery pack 205 to be rapidly dissipated to a normal temperature range. Alternatively, the first vent 2052 or the second vent 2053 can heat the first type battery pack 205, rapidly raising the temperature within the first type battery pack 205 to a normal temperature range.

[0105] Please also see Figures 5 to 8 、 Figure 12 and Figure 13 In one embodiment, the second-type battery pack 206 is provided with a third vent 2062 and a fourth vent 2603. Preferably, the third vent 2062 and the fourth vent 2603 are provided at both ends of the second-type battery pack 206, where the power terminals 2061 are located, and are located below the power terminals 2061 of the second-type battery pack 206. The third vent 2062 and the fourth vent 2603 are provided corresponding to the airflow exchange portions 204 on the two corresponding side panels 216 of the battery compartment 201, respectively. This facilitates the temperature control assembly 203 to remove heat from the interior of the second-type battery pack 206 through the airflow exchange portions 204, or to rapidly heat the interior of the second-type battery pack 206 through the airflow exchange portions 204, allowing the second-type battery pack 206 to quickly return to a normal temperature range.

[0106] In one embodiment, when the second type battery pack 206 needs to be heat-dissipated, the power management device 219 can control the airflow generator 2031 in the temperature control component 203 to operate, and the heater to not operate, and blow air into the interior of the second type battery pack 206 through one of the third vent 2062 and the fourth vent 2603, and discharge the hot air in the second type 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 battery pack 206 can be taken away by heat exchange with the outside, so that the second type battery pack 206 can be quickly cooled to a normal range value.

[0107] In one embodiment, when the second-type battery pack 206 needs to be heated, the power management device 219 can control the airflow generator 2031 and heater in the temperature control assembly 203 to operate simultaneously, blowing air through the third vent 2062 and fourth vent 2603 of the second-type battery pack 206. Furthermore, the housing of the second-type battery pack 206 is provided with exhaust holes 2064 to expel cold air from the second-type battery pack 206, allowing the temperature within the second-type battery pack 206 to quickly rise to a normal range. In one specific embodiment, the exhaust holes 2064 are provided on both sides of the power terminals on the battery pack.

[0108] like Figure 14 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, which is electrically connected to the temperature detection module and processes the temperature information transmitted by the temperature detection module; a plurality of temperature adjustment components 203, which are electrically connected to the power management module; wherein, when the temperature detected by the temperature detection module is within a first range of values, the power management module controls the temperature adjustment component 203 to increase or decrease the temperature of the power supply unit; when the temperature detected by the temperature detection module is within a second range of values, the power management module controls the temperature adjustment component 203 to continue to increase or decrease the temperature of the battery pack, and the power supply unit adopts low current charging or discharging.

[0109] Specifically, the power supply unit includes the first type battery pack 205 or the second type battery pack 206 or a combination of the first type battery pack 205 and the second type battery pack 206 . The first type battery pack 205 and the second type battery pack 206 are both provided with a temperature detection module for detecting the temperature inside the first type battery pack 205 and the second type battery pack 206. The power management module is the above-mentioned power management device 219, which is electrically connected to the temperature detection module. When the temperature inside the first type battery pack 205 or the second type battery pack 206 detected by the temperature detection module is within a first range of values, the power management module controls the temperature adjustment component 203 to increase or decrease the temperature inside the first type battery pack 205 or the second type battery pack 206; when the temperature inside the first type battery pack 205 or the second type battery pack 206 detected by the temperature detection module is within a second range of values, the power management module controls the multiple temperature adjustment components 203 to continue to increase or decrease the temperature of the first type battery pack 205 or the second type battery pack 206. At this time, the first type battery pack 205 or the second type battery pack 206 is charged or discharged with a low current until charging and discharging are completed.

[0110] Thermostatic component 203 includes an airflow generator 2031 capable of generating airflow. When the first range value is higher than the normal operating temperature of the power supply unit, airflow generator 2031 is used to dissipate heat from the power supply unit. When the second range value is greater than the first range value, airflow generator 2031 continues to dissipate heat from the power supply unit.

[0111] The temperature control component 203 includes an airflow generator 2031 capable of generating airflow and a heater capable of generating heat. When the first range value is lower than the normal operating temperature of the power supply unit, the airflow generator 2031 is used to blow the heat generated by the heater to the corresponding power supply unit for heating.

[0112] When the second range value is smaller than the first range value, the airflow generator 2031 is used to blow the heat generated by the heater toward the corresponding power supply unit for heating.

[0113] like Figure 2 In one embodiment, the power supply unit includes a first-type battery pack 205. When the number of first-type battery packs 205 having internal temperatures within a first range of values ​​is m, the number of temperature control components 203 configured to control the temperature of m first-type battery packs 205 is m. Specifically, when the number of first-type battery packs 205 having internal temperatures within a first range of values ​​is one, the number of temperature control components 203 configured to control the temperature of one first-type battery pack 205 is one.

[0114] In one embodiment, the power supply unit includes a first type battery pack 205. When the number of first type battery packs 205 with internal temperatures in the second range of values ​​is m, the number of temperature control components 203 configured to control the temperature of m first type battery packs 205 is at least m+1 and at most all the temperature control components 203 on the outdoor working equipment.

[0115] When the number of first-type battery packs 205 with internal temperatures within the second range is one, the number of temperature control assemblies 203 configured to control the temperature of one first-type battery pack 205 is at least two and at most all temperature control assemblies 203 on the outdoor work equipment. In one embodiment, six temperature control assemblies 203 are provided, and two, three, or five temperature control assemblies 203 may be in operation. However, at most six temperature control assemblies 203 may simultaneously provide heat dissipation or temperature increase processing for one first-type battery pack 205.

[0116] It should be understood that when the number of first-type battery packs 205 installed in the battery compartment 201 is 6, at most 6 temperature control components 203 are required to dissipate heat for the first-type battery packs 205 .

[0117] like Figure 3As shown, in one embodiment, the power supply unit includes a second-type battery pack 206. When the number of second-type battery packs 206 having internal temperatures within a first range of values ​​is n, the number of temperature control components 203 configured to control the temperature of n second-type battery packs 206 is 2n. When the number of second-type battery packs 206 having internal temperatures within the first range of values ​​is one, the number of temperature control components 203 configured to control the temperature of one second-type battery pack 206 is two.

[0118] In one embodiment, the power supply unit includes a second-type battery pack 206. When the number of second-type battery packs 206 with internal temperatures within the second range is n, the number of temperature control assemblies 203 configured to control the temperature of n second-type battery packs 206 is at least 2n+1 and includes at most all temperature control assemblies 203 in the outdoor work equipment. When the number of second-type battery packs 206 with internal temperatures within the second range is one, the number of temperature control assemblies 203 configured to control the temperature of one second-type battery pack 206 is at least three and includes at most all temperature control assemblies 203 in the outdoor work equipment. In one embodiment, six temperature control assemblies 203 are provided, with a maximum of six temperature control assemblies 203 simultaneously providing heat dissipation or heating for one second-type battery pack 206. Alternatively, eight, nine, ten, or even more temperature control assemblies 203 may be provided as needed.

[0119] It should be understood that when the temperature inside the first type battery pack 205 or the second type battery pack 206 is raised or lowered to a normal range, the temperature control component 203 stops operating to save electricity for the first type battery pack 205 or the second type battery pack 206. When the temperature inside the first type battery pack 205 or the second type battery pack 206 is not within the normal range, the temperature control component 203 operates again to regulate the temperature of the first type battery pack 205 or the second type battery pack 206.

[0120] The first range value, the second range value and the normal range value are not limited to a specific range value, are floating, and can be adjusted according to different usage requirements.

[0121] like Figure 9 and Figure 19As shown, in one embodiment, a mounting slot 207 is provided on the battery compartment 201 and on the periphery of the airflow exchange portion 204. The temperature control assembly 203 includes a mounting bracket 2032, an airflow generator 2031 fixed to the mounting bracket 2032, and a heater. When the mounting bracket 2032 is installed and matched with the mounting slot 207, the airflow exchange portion 204 corresponds to the air outlet of the airflow generator 2031. This arrangement allows for quick assembly and disassembly of the temperature control assembly 203 on the battery compartment 201, facilitating replacement and maintenance of the temperature control assembly 203. Specifically, the airflow generator 2031 is fixed to the mounting bracket 2032 by screws. The mounting bracket 2032 is provided with a guide rail 2033. The guide rail 2033 cooperates with the mounting slot 207 to enable the mounting bracket 2032 to be installed outside the battery compartment 201, thereby enabling the airflow generator 2031 to be installed on the battery compartment 201.

[0122] In one embodiment, the bottom of the mounting bracket 2032 is a fixing portion 2034, which is provided with a fixing position 2035. A fixing member such as a bolt can be used to fix the fixing portion 2034 to the battery compartment 201 through the fixing position 2035, thereby fixing the mounting bracket 2032 and the airflow generator on the mounting bracket to the battery compartment 201. After the mounting bracket 2032 is slidably engaged with the mounting slot 207, the mounting bracket 2032 can be fixed to the battery compartment 201 using a fixing member such as a screw.

[0123] like Figures 5 to 8 As shown, in one embodiment, a drainage hole 208 is further provided at the bottom of the battery compartment 201 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 battery pack 205 or the second type battery pack 206.

[0124] like Figure 1 、 Figure 15 and Figure 16 In one embodiment, the outdoor work equipment of the present application includes a frame 100, and the frame 100 is provided with: a seat 400 for users to sit on; a walking assembly 600 for supporting the outdoor work equipment to walk, and the walking assembly 600 includes a front walking wheel 601 and a rear walking wheel 602; a power output assembly 500 for performing outdoor work; a power supply device 200 for supplying power to the outdoor work equipment; the frame 100 includes: a first bearing part 101, at least for carrying the seat 400; a second bearing part 103, at least for carrying the power supply device 200; wherein, the first bearing part 101 and the second bearing part 103 have different heights.

[0125] In one embodiment, the vehicle frame 100 is configured to be divided into a first load-bearing portion 101 and a second load-bearing portion 103 of different heights, so that the vehicle frame 100 can withstand greater impact.

[0126] like Figure 1 and Figure 16 As shown, in one embodiment, the front portion of the frame 100 is a first load-bearing portion 101, which is used to carry a seat 400 for a user to sit on. The rear portion of the frame 100 is used to carry a power supply unit 200. When the height of the second load-bearing portion 103 is lower than that of the first load-bearing portion 101, this helps lower the center of gravity of the entire outdoor work equipment, making the outdoor work equipment more stable during operation. In addition, when the upper height is limited, the rear portion of the frame 100 where the power supply unit 200 is installed is designed to be sunken. This allows the volume of the battery compartment 201 of the power supply unit 200 to be increased to a greater extent within the limited space, allowing the battery compartment 201 to accommodate a larger, high-capacity battery pack, thereby improving the endurance of the outdoor work equipment.

[0127] like Figure 15 In one embodiment, the height difference h between the first supporting portion 101 and the second supporting portion 103 is 100 mm to 150 mm, and the height difference h between the first supporting portion 101 and the second supporting portion 103 is preferably 100 mm, 125 mm, and 150 mm.

[0128] like Figure 16 In one embodiment, the frame 100 is provided with a power fixture 116, which is connected at an angle to the connecting portion 102 and the second load-bearing portion 103. Specifically, if the first load-bearing portion 101 is higher than the second load-bearing portion 103, the connecting portion 102 connecting the first load-bearing portion 101 is at least partially higher than the second load-bearing portion 103. Preferably, the entire height of the connecting portion 102 is higher than the second load-bearing portion 103. The power fixture 116 is preferably a flat plate, with one end of the power fixture 116 overlapping the connecting portion 102 and the other end overlapping the second load-bearing portion 103. This allows the bottom surface of the power fixture 116 to tilt toward the forward direction of the outdoor work equipment. The bottom of the battery compartment 201 is flat. When the battery compartment 201 is placed on the tilted power fixture 116, the compartment opening of the battery compartment 201 can tilt toward the rear of the outdoor work equipment. The tilted opening of the battery compartment 201, facing the rear of the outdoor equipment, facilitates access to and placement of the battery packs when replacing them. The battery packs in this embodiment include the aforementioned first-type battery pack 205 and second-type battery pack 206.

[0129] In one embodiment, the vehicle frame 100 is configured to be divided into a first load-bearing portion 101 and a second load-bearing portion 103 of different heights, so that the vehicle frame 100 can withstand greater impact.

[0130] like Figure 1 and Figure 15As shown, in one embodiment, the height between the lower surface of the first supporting portion 101 and the ground is 279 mm to 381 mm, and preferably the height between the lower surface of the first supporting portion 101 and the ground is 279 mm, 300 mm, and 381 mm. Furthermore, the ratio of the height between the lower surface of the first supporting portion 101 and the ground to the radius of the front running wheel 601 is 2 to 3 times, and preferably the ratio of the height between the lower surface of the first supporting portion 101 and the ground to the radius of the front running wheel 601 is 2 times, 2.5 times, and 3 times.

[0131] In one embodiment, the height between the lower surface of the second supporting portion 103 and the ground is 228 mm to 366 mm, and preferably 228 mm, 300 mm, and 366 mm. Furthermore, the ratio of the height between the lower surface of the second supporting portion 103 and the ground to the radius of the rear running wheel 602 is 1 to 1.2 times, and preferably 1, 1.1, and 1.2 times.

[0132] like Figure 1 、 Figure 15 and Figure 16 The second load-bearing portion 103 is provided with a hook 104 for towing outdoor work equipment. In the up-down direction, the distance between the hook 104 and the axis of the rear running wheel 602 is 200mm to 380mm. In the up-down direction, the distance between the hook 104 and the axis of the rear running wheel 602 is preferably 200mm, 300mm and 380mm. This design is to avoid the vehicle from tipping over due to the hook point being too high or too low during the towing process.

[0133] like Figure 15 In a preferred embodiment, the present application also includes a connecting portion 102 connecting the first bearing portion 101 and the second bearing portion 103. The connecting portion 102 is arranged at an angle, and the angle α4 between the connecting portion 102 and the first bearing portion 101 is 10°~30°. The angle α4 between the connecting portion 102 and the first bearing portion 101 is preferably 10°, 20° and 30°. The angle α5 between the connecting portion 102 and the second bearing portion 103 is 10°~30°. The angle α5 between the connecting portion 102 and the second bearing portion 103 is preferably 10°, 20° and 30°.

[0134] Of course, the first carrying portion 101 and the second carrying portion 103 are arranged horizontally, and the connecting portion 102 can be connected to the first carrying portion 101 and the second carrying portion 103 in a vertical relationship.

[0135] like Figure 15In a preferred embodiment, along the extension direction of the frame 100, the ratio of the lengths of the first load-bearing portion 101, the connecting portion 102 and the second load-bearing portion 103 is L1:L2:L3=5~8:6~10:30~40, and the ratio of the lengths of the first load-bearing portion 101, the connecting portion 102 and the second load-bearing portion 103 is preferably L1:L2:L3=5:6:30, L1:L2:L3=6:8:35 and L1:L2:L3=8:10:40.

[0136] In one embodiment, the first bearing portion 101 , the second bearing portion 103 and the connecting portion 102 are an integrated structure. The integrated frame 100 structure is stronger than the split frame 100 and saves time in assembling the entire outdoor working equipment.

[0137] In one embodiment, the connecting portion 102 and the first load-bearing portion 101 are an integral structure, and the connecting portion 102 and the second load-bearing portion 103 are a split structure; in another embodiment, the connecting portion 102 and the first load-bearing portion 101 are a split structure, and the connecting portion 102 and the second load-bearing portion 103 are an integral structure; in another embodiment, the connecting portion 102 and the first load-bearing portion 101 and the first load-bearing portion 101 are both split structures, and such a design is conducive to disassembling the frame 100 for easy transportation.

[0138] 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 rear end of the frame 100. When the outdoor work equipment is in a rugged area, especially on a road that requires repeated ups and downs, the higher height of the rear end of the frame 100 increases the departure angle of the rear end of the frame 100, which is beneficial to improving the passability of the outdoor work equipment.

[0139] like Figures 17 to 23 As shown, in one embodiment, the outdoor work equipment of the present application includes a frame 100; the frame 100 is provided with: a power supply device 200, which is at least used to power the outdoor work equipment; a power management device 219, which is provided below the power supply device 200 and is at least used to control the charging or discharging of the power supply device 200; and a protective cover 106, which is at least used to protect the power management device 219. The protective cover 106 is provided below the power management device 219 and is provided with a first through hole 108 and a second through hole 110 for at least heat dissipation. The power management device 219 is provided below the power supply device 200, and the protective cover 106 is provided to protect the power management device 219 to prevent damage to the power management device 219 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 to dissipate heat from the power management device 219.

[0140] like Figure 1 、 Figure 17 、 Figure 18 and Figure 23 As shown, the cutting assembly of the outdoor working equipment of the present application is arranged below the frame 100, and the power management device 219 is also arranged below the frame 100 and located behind the cutting assembly. When the outdoor working equipment moves forward and cuts vegetation, debris and other impurities will be thrown out 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. In order to solve the above problem, in one embodiment of the present application, the protective cover 106 is A portion of the lower surface, particularly the portion near the cutting assembly, is designed as a first inclined surface 107, tilted in the direction of travel of the outdoor work equipment. A first through-hole 108 and a second through-hole 110 are provided at the upper and lower ends of the first inclined surface 107, respectively. When the outdoor work equipment is moving forward, the airflow outside the protective cover 106 flows through the first through-hole 108 at a slower rate than that through the second through-hole 110. At least some of the debris that enters the protective cover 106 through the first through-hole 108 is able to flow out of the protective cover 106 through the second through-hole 110 under the action of negative pressure. This ensures effective ventilation of the protective cover 106 while utilizing the Bernoulli principle to effectively expel debris that enters the protective cover 106 through the first through-hole 108 from the protective cover 106 through the second through-hole 110 under the action of negative pressure.

[0141] like Figure 22 As shown, in one 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 difference in flow rate through the first through hole 108 and the second through hole 110, and thus the greater the pressure difference generated, the better the negative pressure effect generated at the second through hole 110, and the better the effect of debris discharge.

[0142] like Figure 23 In one embodiment, the hole area of ​​the first through hole 108 is 60 mm 2 ~80mm 2 The hole area of ​​the first through hole 108 is preferably 60 mm 2 , 70mm 2 and 80mm 2 .

[0143] like Figure 23The area of ​​the second through hole 110 is 3 to 50 times the area of ​​the first through hole 108, and preferably 3, 30, and 50 times the area of ​​the first through hole 108. Designing the first through hole 108 to be small minimizes the ingress of debris into the protective cover 106 while ensuring proper ventilation and heat dissipation. Designing the second through hole 110 to be larger than the first through hole 108 facilitates the discharge of debris that enters the protective cover 106 through the larger second through hole 110.

[0144] like Figure 22 and Figure 23 In one 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 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. The second through hole 110 is located at the junction of the first inclined surface 107 and the second inclined surface 109. The design of the second inclined surface 109 helps to block debris entering the protective cover 106, allowing debris entering the groove 115 to move toward the groove 115 as much as possible, reducing its movement toward the rear of the protective cover 106.

[0145] like Figure 22 In one embodiment, the angle α2 formed between the second inclined surface 109 and the horizontal direction is between 0° and 60°, and preferably between 0°, 30°, and 60°. The larger the angle α2 formed between the second inclined surface 109 and the horizontal direction, the better the debris blocking effect, thereby minimizing the movement of debris toward the rear of the protective cover 106.

[0146] Please also see Figure 22 and Figure 23In one embodiment, in order to discharge debris that is not discharged from the second through-hole 110 and moves to the rear of the protective cover 106, the rear portion of the protective cover 106 of the present application is further provided with a third inclined surface 111 connected to the second inclined surface 109 and arranged obliquely along the forward direction of the outdoor work equipment. The upper end of the third inclined surface 111 is connected to the upper end of the second inclined surface 109. Specifically, the protective cover 106 is provided with a third through-hole 114 at the lower end of the third inclined surface 111. When the outdoor work equipment moves forward, outside the protective cover 106, the speed of airflow through the second through-hole 110 is lower than the speed of airflow through the third through-hole 114. At least some of the debris within the protective cover 106 can flow out of the third through-hole 114 under the action of negative pressure. This helps to discharge the debris that is not discharged from the second through-hole 110 through the third through-hole 114. In this way, the debris entering the protective cover 106 can be effectively discharged from the protective cover 106 again through the secondary negative pressure chip removal process, and the ventilation effect of the protective cover 106 is also ensured.

[0147] like Figure 22 and Figure 23 In one embodiment, the angle α3 between the third inclined surface 111 and the horizontal direction is 10° to 45°, and the angle α3 between the third inclined surface 111 and the horizontal direction is preferably 10°, 13.65° and 45°. The airflow at the first through hole 108 is accelerated in the process of flowing toward the second through hole 110 due to the inclined structural design of the protective cover 106. The accelerated airflow is accelerated again in the process of flowing toward the third through hole 114, so that the negative pressure effect generated at the third through hole 114 is better, and the debris is discharged from the inside of the protective cover 106 to the outside more cleanly.

[0148] like Figure 24As shown, the simulated air flow speed is 3.6 m / s. When blowing from the front to the rear of the outdoor operation setting, the angle of the first inclined surface 107 to the horizontal direction is 52°, and the angle of the third inclined surface 111 to the horizontal direction is 13.65°. The air flow speed near the first through hole 108, the second through hole 110 and the third through hole 114 is as shown in the figure. When the air flow speed is 3.6 m / s, on the outside of the bottom of the protective cover 106, the air flow speed near the first through hole 108 is 3.26 m / s, the air flow speed near the second through hole is 5.15 m / s, and the air flow speed near the third through hole 114 is 5.94 m / s. Obviously, when the air flow speed is 3.6 m / s, the air flow speed near the third through hole 114 is greater than the air flow speed near the second through hole and the air flow speed near the second through hole is greater than First, the air flow velocity near the passage is measured by using the Bernoulli effect (the Bernoulli effect means that in a fluid, if the velocity is low, the pressure is high; if the velocity is high, the pressure is low. The Bernoulli effect is applicable to all ideal fluids including liquids and gases. It is one of the basic phenomena when the fluid is in stable flow, reflecting the relationship between the pressure and flow velocity of the fluid. Specifically, the greater the flow velocity of the fluid, the lower the pressure; the lower 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 the air flow velocity inside. In this way, pressure toward the outside of the protective cover 106 will be generated at the second through hole 110 and the third through hole 114. In this way, when the air flow flows, a negative pressure effect is generated, and debris and the like in the protective cover 106 are discharged through the second through hole 110 and the third through hole 114.

[0149] like Figure 22 and Figure 23 In one 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 configured 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. The flow rate of air flowing through the first through-hole 108, the second through-hole 110, and the third through-hole 114 increases in sequence. This causes the negative pressure generated in the second through-hole 110 and the third through-hole 114 to be greater than that in the first through-hole 108. This helps to discharge debris that enters the protective cover 106 through the first through-hole 108 through the second through-hole 110 and the third through-hole 114, thereby reducing the accumulation of debris in the protective cover 106 and facilitating heat dissipation of the power management device 219 in the protective cover 106.

[0150] like Figure 22 and Figure 23In 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 debris is heavy and the effect of using negative pressure to discharge the debris is limited, in order to facilitate the discharge of debris, 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. The vibration effect of the outdoor work equipment during operation can be used to discharge heavy debris. In order to discharge larger debris, in one embodiment of the present application, the hole area of ​​the second through hole 110 and the third through hole 114 is designed to be larger, so that the height of the upper ends of the second through hole 110 and the third through hole 114 will be higher than the height of the first through hole 108.

[0151] like Figure 23 In one embodiment, the third through hole 114 is designed to be a long strip structure.

[0152] like Figure 23 In one embodiment, a recess 112 is provided at the lower end of the protective cover 106 near the third inclined surface 111, and a third through hole 114 is formed on a side surface of the recess 112. Specifically, the recess 112 is formed by being recessed inward from the outside of the protective cover 106. The recess 112 is composed of a bottom surface and multiple side surfaces, and the third through hole 114 is formed on one of the side surfaces. This can prevent liquid from directly splashing onto the power protection device through the third through hole 114, and can also prevent other hard objects and other impurities from directly splashing onto the power management device 219, so as to avoid damage to the power management device 219.

[0153] In one embodiment, to improve heat dissipation, multiple recesses 112 are provided, each with a corresponding third through-hole 114. The provision of multiple third through-holes 114 also increases the success rate of debris removal. Furthermore, the third through-holes 114 in at least some recesses 112 are oriented differently. Specifically, the recesses 112 are positioned outside the rear portion of the power management device 219, with the third through-holes 114 oriented away from or away from the power management device 219. This prevents liquids or hard objects entering the third through-holes 114 from splashing or impacting the power management device 219, potentially damaging it.

[0154] like Figure 18As shown, in one embodiment, a power supply fixing part 116 is provided on the vehicle frame 100, and the power supply device 200 includes a battery compartment 201 for installing a battery pack, and the battery compartment 201 is fixed above the power supply fixing part 116, and a power management fixing frame 105 is provided below the power supply fixing part 116. The power management device 219 is provided on the power management fixing frame 105, and the power management device 219 is fixed below the battery pack through the power management fixing frame 105 and maintains a certain distance from the battery pack, which is conducive to the heat dissipation between the battery pack and the power management device 219, and does not affect each other.

[0155] like Figure 18 and Figure 21 As shown, in one embodiment, the power management mounting bracket 105 includes connected fixing legs 1051 and a fixing plate 1052. The fixing legs 1051 are used to secure to the power fixture 116, and the fixing plate 1052 is used to mount the power management device 219. The fixing plate 1052 is provided with air holes 1053 for ventilation, facilitating airflow and dissipating heat from 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 to protect the power management device 219. The front baffle 1054 also has baffle openings 1055 corresponding to the power management device 219. When the outdoor work equipment moves forward, air can enter the baffle openings 1055, creating airflow beneath the power management mounting bracket 105 and dissipating heat from the power management device 219.

[0156] See Figure 18 In one embodiment, to optimize the structural layout, the battery compartment 201 of the present application includes two corresponding side panels 216, each of which is provided with an electrical connection terminal 220 for connecting to the battery pack. Horizontally, a power management device 219 is located between the two side panels 216 and can be electrically connected to the electrical connection terminals 220 on the two side panels 216 via a wiring harness. Installing the power management device 219 between the two side panels 216, each provided with an electrical connection terminal 220, allows the power management device 219 to be electrically connected to the electrical connection terminals 220 using a shorter wiring harness, saving wiring harnesses and the space reserved for wiring.

[0157] See Figures 5 to 8 and Figure 18Specifically, three electrical connection terminals 220 are respectively provided on the two side panels 216 of the battery compartment 201 arranged along the front and rear directions of the outdoor working equipment. Correspondingly, the front of the power management device 219 is provided with an interface 217 connected to the electrical connection terminals 220 at the front of the battery compartment 201, and the rear of the power management device 219 is provided with an interface 217 connected to the electrical connection terminals 220 at the rear of the battery compartment 201. This makes the spatial layout of the connection harness of the electrical connection terminals 220 connected to the power management device more reasonable.

[0158] Please also see Figure 20 In one embodiment, the front interface 217 of the power management device 219 can be connected to the vehicle control module, the airflow generator 2031 and the electrical connection terminal 220 through the cable 222 and is located higher than the front interface 217 of the power management device 219. The height of the front interface 217 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 front interface 217 of the power management device 219, so that the lowest end of the cable 222 is below the lowest end of the front baffle 1054. Since the height at which the cable 222 is connected to the vehicle control module, the airflow generator 2031 and the electrical connection terminal 220 is higher than the height of the front interface 217 of the power management device 219, such a setting prevents liquid from flowing into the power management device 219 along the cable 222 when there is liquid on the cable 222, thereby preventing the power management device 219 from getting damp, thereby providing good protection for the power management device 219.

[0159] Furthermore, the battery compartment 201 includes two corresponding side panels 216, each of which is equipped with a cooling fan for dissipating heat from the battery pack. Horizontally, a power management device 219 is located between the two side panels 216 and is electrically connected to the cooling fans on the two side panels 216 via wiring harnesses. This arrangement also effectively reduces the wiring distance between the power management device 219 and the cooling fans.

[0160] like Figure 1 and Figure 18 As shown, in one embodiment, the lower surface of the power management device 219 is tilted toward the forward direction of the outdoor working equipment. With this arrangement, when the outdoor work is moving forward, the bottom surface of the power management device 219 can be in greater contact with the airflow entering through the first through hole 108, thereby 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.

[0161] Furthermore, the protective cover 106 is fixed to the frame 100 and is detachably connected to the frame 100 by means of screws, which makes assembly and disassembly easy.

[0162] like Figure 17 and Figure 18 As shown, in one embodiment, an outdoor working equipment of the present application includes a frame 100; the frame 100 is provided with: a power supply device 200, at least for supplying power to the outdoor working equipment; a power management device 219, fixed below the frame 100, for controlling the charging or discharging of the power supply device 200; a protective cover 106, provided below the power management device 219; wherein, the bottom of the power supply device 200, the frame 100 and the protective cover 106 form a protective space surrounding the power management device 219 to protect the power management device 219 and prevent external liquids or solids from damaging the power management device 219.

[0163] like Figure 23 The bottom of the protective cover 106 is provided with two connected protrusions 113 protruding toward the inside of the protective cover 106. The provision of the protrusions 113 can enhance the strength of the protective cover 106. Secondly, the provision of the protrusions 113 also reduces the excess space in the protective cover 106. Moreover, the protrusions 113 are located between the second through hole 110 and the third through hole 114, so that debris entering the protective cover 106 can be discharged from the third through hole 114 under the delivery action of the protrusions 113, making it difficult for the debris to accumulate in the protective cover 106.

[0164] like Figure 1 、 Figures 25 and 26 As shown, in one embodiment, the present application includes: a frame 100, on which is provided: a walking assembly 600 for supporting the walking of the outdoor working equipment; a power output assembly 500 for performing outdoor work; a seat 400 for the user to sit; a power supply device 200 for supplying power to the outdoor working equipment having a tail cover 210; the tail cover 210 is provided on the power supply device 200, and the tail cover 210 is provided with at least: a reversing radar 213: the reversing radar 213 is used to monitor the rear area of ​​the outdoor working equipment when it is reversing and moving; a tail light 214, which at least displays the operating status of the outdoor working equipment having the tail cover 210.

[0165] In one embodiment, the tail cover 210 includes a main board 2101 located at the rear of the outdoor working equipment and a sub-board 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 arranged corresponding to the rear panel, and the sub-board 2102 is arranged corresponding to the side panel. 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 in the battery compartment 201 in the event of a bump, and also makes the rear of the entire outdoor working equipment beautiful and simple.

[0166] like Figure 27 As shown, in one embodiment, the taillight 214 includes a main light portion 2141 located on the main board 2101 and a sub-light portion 2142 extending from both ends of the main light portion 2141 to the sub-board 2102; when the user is located on the side or behind the outdoor work equipment, the status of the taillight 214 can be observed. Such a setting is conducive to the user being able to directly observe the flashing of the taillight 214 at multiple positions, which helps the user understand whether the battery pack and the battery compartment 201 are installed in place.

[0167] like Figure 28 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 a receiving space 211 is formed between the tail cover 210 and the battery compartment 201. The reversing radar 213 is located in the receiving space 211, which protects the reversing radar 213.

[0168] like Figure 28 As shown, in one embodiment, a cooling fan for dissipating heat from the battery pack is provided on a side panel 216 of the battery compartment 201. A receiving space 211 is formed between the tail cover 210 and the battery compartment 201. The cooling fan and the wiring harness connected to the cooling fan are located within the receiving space 211. This arrangement ensures that the cooling fan has space for air circulation while also protecting the cooling fan and its wiring harness, preventing debris from contaminating the cooling fan and the wiring harness.

[0169] like Figure 16 As shown, in one embodiment, a charging connector 218 is further provided on the battery compartment 201 . The charging connector 218 is directly installed on the battery compartment 201 , and the battery pack in the battery compartment 201 can be directly charged through the charging connector 218 .

[0170] In one embodiment, the charging connector 218 is set at an angle with the horizontal direction. The angle between the charging connector 218 and the horizontal direction can be greater than or equal to 0° and less than or equal to 90°, preferably 45° and 60°. Such a design of 45° and 60° angles helps the user to plug and unplug the charging connector 218.

[0171] See also Figure 27 As shown, in one embodiment, a mounting seat 223 for mounting a charging connector 218 is provided on the battery compartment 201, the tail cover 210 is installed on the mounting seat 223, and a charging avoidance port 212 for exposing the charging connector 218 is provided on the tail cover 210. The charging connector 218 passes through the charging avoidance port 212 of the tail cover 210 and is connected to the charging gun.

[0172] Please also see Figure 19 In one embodiment, the mounting base 223 includes a mounting surface 2231, which faces the upper and rearward portion of the outdoor equipment. Mounting surface 2231 is provided with a perforation, and the charging connector 218 is provided with a mounting plate 2181. The charging connector 218 is provided on both sides of the mounting plate 2181. During installation, one end of the charging connector 218 is inserted through the perforation, allowing the mounting plate 2181 to be aligned with the mounting surface 2231, and then the two are fixed together using screws. Because the mounting surface 2231 faces the upper and rearward portion of the outdoor equipment, this arrangement allows the charging connector 218 to be tilted toward the upper and rearward portion of the outdoor equipment when mounted on the mounting surface 2231, facilitating connection with the charging gun.

[0173] In one embodiment, the angle between the mounting surface 2231 and the horizontal direction is greater than or equal to 0° and less than or equal to 90°, preferably 45° and 60°, so that the upper charging connector 218 installed on the mounting surface 2231 can be tilted backward at 45° or 60°. The angle setting is reasonable, which is convenient for users to plug and unplug the charging gun.

[0174] Furthermore, the mounting seat 223 also 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 on the inner side below the mounting surface 2231, so that while supporting the mounting surface 2231, they occupy a smaller space.

[0175] In one embodiment, the mounting seat 223 is provided corresponding to a temperature control component. In order not to affect the exhaust or air intake of the temperature control component, the present application provides exhaust holes 2232 on the sides of the first panel 2237, the second panel 2238 and the mounting surface 2231, which is conducive to the exhaust or air intake of the temperature control component.

[0176] In one embodiment, a connecting portion 2233 is further provided below the second panel 2238 . The connecting portion 2233 is used to connect to the power fixture 116 , so that the mounting base 223 is installed more firmly.

[0177] In one embodiment, a connecting sub-board 2234 is provided on the side of the mounting base 223 , and a radar controller 2235 is provided on the connecting sub-board 2234 . The radar controller 2235 is electrically connected to the reversing radar 213 .

[0178] In one embodiment, the taillight 214 is disposed above the tail cover 210 , a charging connector 218 is disposed below the taillight 214 , and the charging connector 218 is disposed in the middle of the tail cover 210 , and the reversing radar 213 is disposed on both sides of the charging connector 218 and is substantially flush with the reversing radar 213 .

[0179] In one embodiment, the reversing radar 213 can be directly installed on the battery compartment 201, or on the vehicle frame 100. Of course, the reversing radar 213 can also be installed on the seat 400. The corresponding selection and design can be made according to actual usage requirements.

[0180] like Figure 25 and Figure 26 As shown, according to ergonomic analysis, in the horizontal direction, the frame 100 is symmetrically distributed left and right with the direction in which the frame 100 extends as the center line Z, and the center of the seat 400 is located on the center line Z. When the driver is sitting still on the outdoor work equipment, the area in front of the driver about 30° to the left and right of the center line Z (the S1 area has an angle of 60°) is the best field of vision area, about 60° to the left and right (the S2 area has an angle of 120°) is the normal binocular clear field of vision area, and the area within the unilateral angle range of 60° to 95° (the S3 area) is the visible blurred area.

[0181] Because the driver is always in motion while operating a vehicle, their effective visual perception angle is reduced compared to a stationary state. Based on ergonomics theory, a 120° clear dual-view area is used as a reference. The visual field simulation diagram shows that when the driver is operating normally (holding the operating assembly 300), the maximum clear visual field achieved by turning the head left and right is 300° (area S4). There is a 60° blind spot directly behind the vehicle (area S2).

[0182] like Figure 25 and Figure 26As shown, in order to compensate for the 60° blind spot behind the vehicle, in one embodiment, the outdoor working equipment of the present application includes a frame 100; a walking assembly 600, which is arranged on the frame 100 and is configured to support the walking of the outdoor working equipment; a cutting assembly, which is arranged on the frame 100 and is configured to cut vegetation; a seat 400, which is arranged on the frame 100 and is configured for the user to sit on. When the user operates the outdoor working equipment on the seat 400, it can cover at least 300° of the field of view in front and on both sides of the outdoor working equipment in the horizontal direction; a detection assembly, which is arranged at the rear of the outdoor working equipment, and the detection assembly detects at least 60° in the horizontal direction, wherein the user's field of view and the detection range of the detection assembly can cover the four sides of the outdoor working equipment at full angles in the horizontal direction.

[0183] like Figure 26 As shown, in one embodiment, the length range of the spatial area (S6) detected by the detection component is 1.4m to 1.6m, the width range is 1.5m to 1.7m, and the height range is 1.1m to 1.3m. Preferably, the length of the spatial area (S6) detected by the detection component is 1.4m, 1.5m and 1.6m, the width is 1.5m, 1.6m and 1.7m, and the height is 1.1m, 1.2m and 1.3m.

[0184] like Figure 25 In one embodiment, the distance between the space area (S6) and the outdoor working equipment is greater than or equal to 100 mm and less than or equal to 250 mm, and the distance between the space area (S6) and the outdoor working equipment is preferably 100 mm, 180 mm and 250 mm.

[0185] like Figure 26 In one embodiment, the distance between the space area (S6) and the working surface is greater than or equal to 100 mm and less than or equal to 200 mm. The distance between the space area (S6) and the working surface is preferably 100 mm, 150 mm, and 200 mm.

[0186] like Figure 27 In one embodiment, preferably, the detection component includes a reversing radar 213, and two reversing radars 213 are provided on both sides of the center line, and the distance between the two reversing radars 213 is 350mm to 400mm, preferably 360mm.

[0187] like Figure 25 In one embodiment, the height of the reversing radar 213 from the ground is 320mm to 360mm. The height of the reversing radar 213 from the ground is preferably 320mm, 340mm and 360mm. Such a height setting can cover children and small animals with shorter height to prevent accidental injuries.

[0188] It should be understood that the battery compartment 201 is also provided with a radar controller 2235 for controlling the reversing radar 213. The radar controller 2235 is used to receive the signal of the reversing radar 213 and then connect to the vehicle control module through the CAN communication signal. It can also transmit instructions to control the vehicle alarm system (alarm sound) to remind the driver to pay attention to avoid collision incidents.

[0189] The radar controller 2235 may also be connected to the vehicle control module via a power management device.

[0190] like Figures 29 to 31 As shown, in one embodiment, outdoor work equipment includes a frame 100, on which are disposed: a travel assembly 600 for supporting the outdoor work equipment in travel; a power output assembly 500 for performing outdoor work; a seat 400 for a user to sit on; a power supply unit 200 for powering the outdoor work equipment; and a storage box 700 for storing at least some equipment, with the storage compartment being located between the seat 400 and the power supply unit 200. The placement of the storage box 700 between the seat 400 and the power supply unit 200 utilizes the excess space between the seat 400 and the power supply unit 200. Furthermore, the location of the storage box 700 next to the seat 400 allows the user to more conveniently access equipment, such as tools or other items, within the storage box 700 when using the outdoor work equipment.

[0191] In one embodiment, the storage box 700 at least partially overlaps with the seat and the power supply device 200 along the travel direction of the outdoor work equipment. The storage box 200 may also be completely located between the seat 400 and the power supply device 200 .

[0192] like Figure 30 In one embodiment, a storage box 700 is positioned near one end of the power supply unit 200, and an extension plate 701 is provided on each side of the storage box 700. The extension plates 701 on both sides overlap with the power supply unit 200 to form a receiving cavity 209. Since the battery compartment 201 of the present application is provided with a cooling fan, the receiving cavity 209 is provided to form a ventilation channel to facilitate the dissipation of heat from the battery pack in the battery compartment 201. In addition, the wiring harness connected to the cooling fan can also be accommodated in the receiving cavity 209, providing protection for the cooling fan and the wiring harness.

[0193] like Figure 30 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. Two extension plates 701 are overlapped with the reinforcing ribs 215 respectively. Specifically, the reinforcing ribs 215 are provided on the outer wall of the battery compartment 201, and one extension plate 701 is overlapped with one reinforcing rib 215.

[0194] like Figure 29 In one embodiment, the seat 400 includes a cushion portion 401 and a backrest portion 402. Slide rails are provided between the vehicle frame 100 and the seat 400, extending along the fore-aft direction of the vehicle frame 100. The seat 400 can move along the fore-aft direction of the vehicle frame 100 on the slide rails. When the seat 400 moves to the rearmost position on the slide rails, the backrest portion 402 is at least partially located directly above the storage box 700. This arrangement provides a certain degree of cover for items in the storage box 700, reducing the risk of items falling out of the storage box 700 due to vehicle jolting.

[0195] like Figure 29 In one embodiment, the storage box 700 is located below the seat 400 in the up and down direction, so as to avoid the storage box 700 interfering with the front and rear adjustment of the seat 400.

[0196] In one embodiment, a cover is provided at the opening of the storage box 700 to prevent debris from falling into the interior of the storage box 700 , thereby preventing the items in the storage box 700 from being damaged or contaminated.

[0197] like Figure 29 In one embodiment, the storage box 700 is detachably mounted on the vehicle frame 100 and does not cause interference when the seat 400 or the power supply device 200 is disassembled or assembled.

[0198] Of course, the storage box 700 can also be configured to install a battery pack to power outdoor work equipment. When it is necessary to increase the battery life of the outdoor work equipment to increase the working area, the storage box 700 in this application can also be used to install a battery pack. The battery pack is connected to the power management device 219 through a wiring 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 supply. When the power in the battery compartment 201 is exhausted or about to be exhausted, the battery pack in the storage box 700 powers the outdoor work equipment to support the outdoor work equipment to return to the work position or continue outdoor work. Of course, the battery pack in the storage box 700 can also power the above-mentioned temperature control component 203 to reduce the power supply pressure of the first type battery pack 205 or the second type battery pack 206.

[0199] In one embodiment, the volume of the storage box 700 is 3 L to 20 L. The volume of the storage box 700 is preferably 3 L, 6.6 L, and 20 L.

[0200] like Figure 31In one embodiment, a charging port is provided on the storage box 700. The charging port can be electrically connected to the battery pack in the battery compartment 201, and can also be electrically connected to the battery pack set in the storage box 700. The charging port can charge 3C products such as mobile phones, music players, etc., and can also power other garden tools.
