[0125] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. For example, terms indicating orientation or positional relationships such as "upper", "lower", "left", "right", "front", and "rear" are only based on the orientation or positional relationships shown in the drawings. They are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as a limitation to this application.

[0126] Exemplarily, when a user is sitting on an outdoor garden lawn mower located on the ground, the direction the user faces is defined as the front, the direction the user's back faces is defined as the rear, the direction on the user's left hand side is defined as the left, the direction on the user's right hand side is defined as the right, the direction close to the ground is defined as the lower, and the direction away from the ground is defined as the upper.

[0127] Please refer to Figure 1 and Figure 2 Shown is an outdoor garden lawn mower according to an embodiment of this application, which is widely used in fields such as vegetation trimming. The outdoor garden lawn mower includes a main frame 1, a seat, a cutting assembly 2, a traveling assembly 3, an operating assembly 4, and a power supply device 5. The main frame 1 extends along a first linear direction 101 parallel to the front-rear direction. Among them, the seat is installed on the main frame 1 for the user to sit on. The main frame 1 is also used to install the cutting assembly 2, the traveling assembly 3, the operating assembly 4, and the power supply device 5. The power supply device 5 is used to provide an energy source for the cutting assembly 2 and the traveling assembly 3, so that the cutting assembly 2 performs a cutting operation and the traveling assembly 3 supports the main frame 1 and the related components on the main frame 1 to travel.

[0128] Specifically, the cutting assembly 2, as a power output component, is used to output power to achieve the lawn mowing function of the electric lawn mower. The cutting assembly 2 is set to 2 groups or 3 groups. The cutting assembly 2 is arranged below the main frame 1. In one embodiment, the cutting assembly 2 includes: a cutter head, a lawn mowing element, and a lawn mowing motor. The lawn mowing element is used to cut vegetation when rotating at a high speed. For example, the lawn mowing element is a blade for cutting vegetation on a lawn. The cutter head forms a lawn mowing space for accommodating the lawn mowing element, and the lawn mowing element is at least partially located in the lawn mowing space. In some embodiments, the number of lawn mowing elements can be 2, and the number of lawn mowing motors can also be 2. Correspondingly, the two lawn mowing motors respectively drive the two lawn mowing elements. In some embodiments, the number of lawn mowing elements can be 3, and correspondingly, the number of lawn mowing motors is also 3. The three lawn mowing motors respectively drive the three lawn mowing elements. Of course, the cutting assembly 2 can also be detached from the outdoor garden lawn mower. In some embodiments, the cutting assembly 2 can be replaced with a snow plowing assembly or other assemblies. Therefore, the outdoor garden lawn mower can not only cut vegetation but also be applied to other fields such as snow plowing.

[0129] The traveling assembly 3 includes traveling wheels disposed on the main frame 1 and a traveling motor for driving the traveling wheels. The traveling wheels are arranged on both sides of the main frame 1 so that the center of gravity of the outdoor garden lawn mower is kept within the main frame 1, thereby reducing the probability of the outdoor garden lawn mower tipping over during traveling. In one embodiment, the number of traveling wheels is set to 4, including 2 front traveling wheels and 2 rear traveling wheels respectively. The front traveling wheels can be universal wheels. The traveling motor is connected to the rear traveling wheels and drives the rear traveling wheels to rotate. The 2 rear traveling wheels are both matched with the traveling motor, and the rotational speeds of the 2 traveling motors can be the same or different. When the user rides the outdoor garden lawn mower straight ahead, the rotational speeds of the two traveling motors are substantially the same; when the user rides the outdoor garden lawn mower to turn, the rotational speeds of the two traveling motors are different, and the outdoor garden lawn mower turns to the side with the lower rotational speed of the traveling motor. In some embodiments, the diameter of the front traveling wheels is smaller than that of the rear traveling wheels. Of course, the number of traveling wheels can also be set to 3 or 5.

[0130] The operation assembly 4 includes a first operating lever and a second operating lever disposed on the left and right sides of the outdoor garden lawn mower. The user controls the outdoor garden lawn mower to move forward, backward or turn by manipulating the first operating lever and the second operating lever. The operation assembly 4 can also be a steering wheel capable of controlling the outdoor garden lawn mower. This application also includes a brake assembly, which is disposed on the upper surface in front of the main frame 1 for the user to step on to control the operating state of the outdoor garden lawn mower.

[0131] Please also refer to Figure 38 、 Figure 39 and Figure 40 As shown, the power supply device 5 includes a first type of battery pack 52, a second type of battery pack 53 and a battery compartment 51. In some embodiments, the power supply device 5 is disposed at the rear of the outdoor garden lawn mower. The first type of battery pack 52 and the second type of battery pack 53 have the same electrical connection joints. The electrical connection joint of the first type of battery pack 52 includes a plurality of first terminal slots 521, and the electrical connection joint of the second type of battery pack 53 includes a plurality of second terminal slots 531. The structures of the first terminal slots 521 and the second terminal slots 531 are the same. An electrical connection terminal 513 capable of forming an electrical connection with the electrical connection joint is also disposed on the side wall of the battery compartment 51. When the first type of battery pack 52 is mated with the battery compartment 51, a plurality of first terminal slots 521 are inserted and mated with the electrical connection terminal 513. When the second type of battery pack 53 is mated with the battery compartment 51, a plurality of second terminal slots 531 are inserted and mated with the electrical connection terminal 513, so that the power supply device 5 supplies power to the outdoor garden lawn mower to complete the established outdoor operations. Compared with the traditional use of fossil fuels as the energy source, the outdoor garden lawn mower of this application is more environmentally friendly and more in line with the long-term development plan.

[0132] It should be noted that both the first - type battery pack 52 and the second - type battery pack 53 can be mated with the electrical connection terminal 513. There is no need to set two types of electrical connection terminals, which makes the structure of the battery pack more compact and simple, and is conducive to realizing the simplified design of the battery pack.

[0133] In some embodiments, the size of the first - type battery pack 52 is generally set to be smaller than that of the second - type battery pack 53. In a conventional setting, the electrical capacity of the battery pack is proportional to its size, that is, the smaller the size of the battery pack, the smaller the electrical capacity; the larger the size of the battery pack, the larger the electrical capacity.

[0134] As Figures 3 - 5 shown, in one embodiment, the battery compartment 51 includes a first side wall and a second side wall which are oppositely arranged. At least one pair of the plurality of electrical connection terminals 513 are respectively arranged on the first side wall and the second side wall, and can be detachably electrically connected to the first - type battery pack 52 and / or the second - type battery pack 53. In order to enable the electrical connection terminal 513 at one mating position of the battery compartment 51 to form electrical connections with both the first - type battery pack 52 and the second - type battery pack 53, in one embodiment, an electrical connection terminal 513 is respectively arranged on the first side wall and the second side wall on the opposite sides of the battery compartment 51. Such a setting enables the two electrical connection terminals 513 to either electrically connect two first - type battery packs 52 respectively or electrically connect one second - type battery pack 53. Multiple pairs of electrical connection terminals 513 can also be set to meet the requirements of using multiple second - type battery packs 53 simultaneously.

[0135] In one embodiment, the electrical connection terminal 513 includes a positive terminal and a negative terminal, which are used to connect with the electrical connection joints of the first - type battery pack 52 or the second - type battery pack 53.

[0136] In one embodiment, the first - type battery pack 52 is only provided with one electrical connection joint, and the positive and negative poles of the electrical connection joint are located on the same side, and can be connected to the positive terminal and the negative terminal of the electrical connection terminal 513, so that one electrical connection terminal 513 can connect one first - type battery pack 52 to form an electrical connection. A second - type battery pack 53 is provided with two electrical connection joints, which are located on its opposite sides. One of the electrical connection joints can be connected to one of the electrical connection terminals 513 arranged on the opposite sides, and the other electrical connection joint can be connected to the other electrical connection terminal 513 to form an electrical connection. Of course, the two electrical connection terminals of the second - type battery pack 53 can also be arranged on the same side.

[0137] In one embodiment, both the first - type battery pack 52 and the second - type battery pack 53 can supply power to the mowing motor and the traveling motor.

[0138] In a preferred embodiment, both the first type of battery pack 52 and the second type of battery pack 53 can be removed from the outdoor garden lawn mower and still power other power tools.

[0139] In a preferred embodiment, as Figure 2 , Figure 3 and Figure 11 shown, along a direction perpendicular to or parallel to the first straight line direction 101, the orthographic projections between at least a pair of electrical connection terminals 513 provided on the first side wall and the second side wall of the battery compartment 51 at least partially overlap. Between the paired electrical connection terminals 513 provided on opposite sides of the battery compartment 51, the orthographic projection along a direction perpendicular to or parallel to the first straight line may be completely overlapping, partially overlapping, completely non-overlapping, or a combination of at least any two of completely overlapping, partially overlapping, or completely non-overlapping, which can be specifically adjusted according to actual requirements to match the design requirements of the battery compartment 51, enriching the mating methods between the battery compartment 51 and the battery pack, and thus improving the matching degree between the outdoor garden lawn mower and different types of battery packs.

[0140] In another embodiment, along a direction perpendicular to or parallel to the first straight line direction 101, the orthographic projections between at least a pair of electrical connection terminals 513 provided on the first side wall and the second side wall of the battery compartment 51 do not overlap. That is, for the paired electrical connection terminals 513, at least one pair or multiple pairs or all of the orthographic projections along a direction perpendicular to or parallel to the first straight line direction 101 do not overlap, which can be specifically adjusted according to actual requirements to optimize the actual use requirements of the structure of the battery compartment 51.

[0141] As Figure 4 shown, correspondingly, the first type of battery pack 52 or the second type of battery pack 53 is provided with a chute that is pluggably connected to the track 514, that is, the first type of battery pack 52 or the second type of battery pack 53 shares a track 514. The chutes on the first type of battery pack 52 or the second type of battery pack 53 can be the same or different, as long as both can form a pluggable relationship with the track 514 on the battery compartment 51. Generally, one chute and one track 514 form a group, and at least one group of chutes and rails is provided between a battery pack and the battery compartment 51, or two groups or more groups can also be provided.

[0142] In an embodiment, the first type of battery pack 52 and the second type of battery pack 53 can also respectively use different tracks 514, as long as they satisfy the condition of commonly connecting to the same electrical connection terminal 513 to achieve electrical connection by quick plugging and unplugging.

[0143] In some embodiments, in addition to using the cooperation of the sliding groove and the track 514 to achieve the plug-in installation of the first type of battery pack 52 or the second type of battery pack 53 and the battery compartment 51, other structures can also be used to achieve the installation cooperation between the first type of battery pack 52 or the second type of battery pack 53 and the battery compartment 51. For example, a groove is provided at the bottom of the first type of battery pack 52 or the second type of battery pack 53, and a rib matching the groove is provided at the bottom of the battery compartment 51. Any structure that can provide installation guidance or installation stability is acceptable.

[0144] In an exemplary embodiment, the battery compartment 51 includes a first battery compartment 511 for accommodating the first type of battery pack 52 and a second battery compartment 512 for accommodating the first type of battery pack 52 and / or the second type of battery pack 53. The first battery compartment 511 is generally set to be smaller and can only accommodate the first type of battery pack 52. The second battery compartment 512 is generally set to be larger and can accommodate the first type of battery pack 52 or the second type of battery pack 53. In one embodiment, the first battery compartment 511 and the second battery compartment 512 are isolated from each other, and the first battery compartment 511 is located outside the second battery compartment 512. Preferably, the first battery compartment 511 is provided on both sides of the second battery.

[0145] As Figures 6 - 9 shown, in some embodiments, taking the Figure 5 structure of the battery compartment 51 as an example, the combination of the first type of battery pack 52 and the second type of battery pack 53 on the outdoor garden lawn mower includes the following: 2 first type of battery packs 52 and 2 second type of battery packs 53, or 4 first type of battery packs 52 and 1 second type of battery pack 53, or 6 first type of battery packs 52.

[0146] In one embodiment, the battery compartment 51 is provided in a generally integral rectangular housing structure, and the arrangement of the battery packs is as Figures 10 - 15 shown, including the following ways: it can accommodate 3 second type of battery packs 53, or 2 second type of battery packs 53 and 2 first type of battery packs 52, or 1 second type of battery pack 53 and 4 first type of battery packs 52, or 6 first type of battery packs 52.

[0147] As Figures 16 - 20As shown, in one embodiment, the battery compartment 51 includes a third side wall and a fourth side wall that are arranged opposite to each other, and the third side wall of the battery compartment 51 at least partially protrudes in a direction away from the fourth side wall to form a sub-compartment 515 that can accommodate the first type battery pack 52 or the second type battery pack 53, and the fourth side wall is provided with a terminal mounting seat on the side close to the third side wall, and the terminal mounting seat is at least used to install the electrical connection terminal 513. Preferably, the third side wall is arranged to protrude along the first straight line direction 101. In this way, the battery compartment 51 is configured as a whole compartment body, similar to a "T"-shaped structure, which fits better with the space behind the outdoor garden mower, and realizes more full use of the space behind the outdoor garden mower. Specifically, such a battery compartment 51 design can accommodate 3 second type battery packs 53, or 2 second type battery packs 53 and 2 first type battery packs 52, or 1 second type battery pack 53 and 4 first type battery packs 52, or 6 first type battery packs 52.

[0148] In some embodiments, the battery compartment 51 may also be configured as a plurality of compartment bodies of different sizes, and the number of the compartment bodies may be 3, 4, 5 or more.

[0149] like Figures 21 - 26 As shown, in some embodiments, taking the second type battery pack 53 as an example, the cross-sectional structure of the battery pack perpendicular to the insertion direction may be rectangular, elliptical, diamond, circular or other polygonal, or may be roughly rectangular, etc. Figure 27 The same shapes can also be arranged in different combinations in the battery compartment 51, such as Figure 22 and Figure 23 and Figure 24 and Figure 25 shown.

[0150] In one embodiment, in order to drive the outdoor garden lawn mower to operate, at least one first type battery pack 52 or one second type battery pack 53 is installed in the battery compartment 51 to supply power to the outdoor garden lawn mower.

[0151] like Figure 35 As shown, in one embodiment, a cover 54 is pivotally connected to an edge of the battery compartment 51 opening, and the cover 54 is connected to the battery compartment 51 through a rotating pin, driving the cover 54 to open and close so that the battery compartment 51 switches between open and closed. A gas spring 55 is also connected between the battery compartment 51 and the battery compartment 51 to support the opening and closing of the cover 54. The shape of the cover 54 matches the shape of the opening of the battery compartment 51, and is not limited to the attached Figure 35 The structure of the bin cover 54 shown can be rectangular, circular, etc.

[0152] The battery compartment 51 includes a recessed groove, and the first type of battery pack 52 or the second type of battery pack 53 can be detachably inserted into the groove along the second linear direction 102 and can also be pulled out from the groove along the second linear direction 102.

[0153] In one embodiment, the first linear direction 101 intersects the second linear direction 102. Further, the included angle between the first linear direction 101 and the second linear direction 102 is less than 60 degrees. Preferably, the included angle between the first linear direction 101 and the second linear direction 102 is 30 degrees, 45 degrees or 59 degrees.

[0154] In one embodiment, the first linear direction 101 is parallel to the second linear direction 102, that is, the groove also extends along the first linear direction 101.

[0155] In one embodiment, the first linear direction 101 is perpendicular to the second linear direction 102.

[0156] In one embodiment, the insertion angles of the first type of battery pack 52 and the second type of battery pack 53 into the battery compartment 51 are different, or the insertion angles between multiple first type of battery packs 52 are different, or the insertion angles between multiple second type of battery packs 53 are different.

[0157] Multiple first type of battery packs 52 or multiple second type of battery packs 53 can be assembled with the outdoor garden mower in a form perpendicular to the first linear direction 101. Specifically, multiple first type of battery packs 52 or multiple second type of battery packs 53 can be arranged in parallel at the same height, as Figure 28 shown; or multiple first type of battery packs 52 or multiple second type of battery packs 53 are arranged at different heights, approximately in a stepped arrangement, as Figure 29 shown; or multiple first type of battery packs 52 or multiple second type of battery packs 53 are arranged in a staggered manner of low-high-low, as Figure 30 shown. Setting the installation heights of the battery packs to different heights helps to pick up and place the battery packs.

[0158] Further, multiple first type of battery packs 52 or multiple second type of battery packs 53 can also be assembled with the outdoor garden mower in a form at an angle to the first linear direction 101, that is, multiple first type of battery packs 52 or multiple second type of battery packs 53 are arranged in an inclined and staggered form.

[0159] As Figure 31 shown, multiple first type of battery packs 52 or multiple second type of battery packs 53 can also be assembled in the battery compartment 51 in a stacked manner in the up-down direction.

[0160] As Figure 32 andFigure 33 As shown, taking the second type of battery pack 53 as an example, looking down at the outdoor garden mower from above the battery compartment 51, the heights of the second type of battery pack 53 are different in the first straight direction 101. Preferably, they are arranged in a stepped form or in a high-low-high form in the first straight direction.

[0161] In one embodiment, in addition to being arranged at the rear side of the outdoor garden mower, the first type of battery pack 52 and the second type of battery pack 53 can also be arranged on both sides or the front side of the outdoor garden mower. Such an arrangement can improve the endurance of the outdoor garden mower.

[0162] In one embodiment, the volume ratio of the first type of battery pack 52 to the second type of battery pack 53 is 0.01 - 0.9. Preferably, the volume ratio of the first type of battery pack 52 to the second type of battery pack 53 is 0.2.

[0163] In a preferred embodiment, the length, width, and height of the first type of battery pack 52 are: 188.5 mm, 124 mm, and 160 mm, and the length, width, and height of the second type of battery pack 53 are: 371 mm, 179 mm, and 221 mm. Such an arrangement enables the first type of battery pack 52 and the second type of battery pack 53 to better utilize the space of the battery compartment 51, without causing space waste, nor making it inconvenient to place the larger-sized second type of battery pack 53 into the battery compartment 51 due to a smaller space.

[0164] As Figure 34 shown, in one embodiment, the battery compartment 51 is arranged at the rear of the outdoor garden mower, and the distance L from the lowest point of the battery compartment 51 to the ground is at least 380 mm. Such an arrangement makes it difficult for the outdoor garden mower to touch the slope when going uphill or downhill, thereby reducing the probability of damage to the battery compartment. Preferably, the distance L from the lowest point of the battery compartment 51 to the ground is 430 mm or 450 mm. The angle between the tangent line from the protruding point at the rear end of the outdoor garden mower body to the rear walking wheel and the ground is α. The larger the angle α, the lower the probability of the battery compartment 51 touching the ground. The relatively high height of the battery compartment 51 also helps to reduce the degree of bending when the user takes and places the battery pack, optimizing the user experience.

[0165] In one embodiment, the energy density of the first type of battery pack 52 is greater than or equal to 200 wh / kg and less than or equal to 500 wh / kg, and the energy density of the second type of battery pack 53 is greater than or equal to 100 wh / kg and less than or equal to 250 wh / kg. Preferably, the energy density of the first type of battery pack 52 is 200 wh / kg, 300 wh / kg, or 500 wh / kg, and the energy density of the second type of battery pack 53 is 100 wh / kg, 120 wh / kg, or 250 wh / kg.

[0166] In one embodiment, the capacitance of the first type of battery pack 52 is greater than or equal to 90 wh and less than or equal to 1000 wh, and the capacitance of the second type of battery pack 53 is greater than or equal to 1000 wh. Preferably, the capacitance of the first type of battery pack 52 is 90 wh, 300 wh or 1000 wh, and the capacitance of the second type of battery pack 53 is 1000 wh, 13000 wh or 24000 wh. When the area to be mowed is small, only the first type of battery pack 52 can be selected to supply power to the outdoor garden lawn mower. The first type of battery pack 52 is smaller in volume, so the weight is also smaller, reducing the burden on the user when carrying the battery pack. When the area to be mowed is medium, the first type of battery pack 52 and the second type of battery pack 53 can be selected to supply power to the outdoor garden lawn mower. When the area to be mowed is large, multiple second type of battery packs 53 can be selected to supply power to the outdoor garden lawn mower to increase the endurance of the outdoor garden lawn mower without repeatedly charging or replacing the battery.

[0167] In some embodiments, such as Figure 12 and Figure 17 shown, when 3 second type of battery packs are selected to supply power to the outdoor garden lawn mower, the 3 second type of battery packs can provide a total discharge capacity of at least 20000 wh. As Figure 6 , Figure 13 and Figure 18 shown, when 2 first type of battery packs 52 and 2 second type of battery packs 53 are selected to supply power to the outdoor garden lawn mower, the 2 first type of battery packs 52 and the 2 second type of battery packs 53 can provide a total discharge capacity of at least 15000 wh; as Figure 7 , Figure 8 , Figure 14 and Figure 19 shown, when 4 first type of battery packs and 1 second type of battery pack are selected to supply power to the outdoor garden lawn mower, the 4 first type of battery packs and the 1 second type of battery pack can provide a total discharge capacity of at least 10000 wh; as Figure 9 , Figure 15 and Figure 20 shown, when 6 first type of battery packs 52 are selected to supply power to the outdoor garden lawn mower, the 6 first type of battery packs 52 can provide a total discharge capacity of at least 6000 wh.

[0168] In one embodiment, an identification terminal for identifying the first type of battery pack 52 and the second type of battery pack 53 is further provided at the electrical connection terminal 513 of the outdoor garden lawn mower. The type of the battery pack is identified through the identification terminal so as to adjust the working power of the outdoor garden lawn mower.

Preferably, the discharge power of the first type of battery pack 52 is 2000w, 3000w or 4350w, and the discharge power of the second type of battery pack 53 is 3500w, 5000w or 6960w. The first type of battery pack 52 is suitable for small-area vegetation cutting operations, facilitating handling, disassembly and assembly. The second type of battery pack 53 is suitable for large-area vegetation cutting operations, with a long endurance and no need for repeated charging or mid-course battery pack replacement.

[0170] In some embodiments, such as Figure 12 and Figure 17 shown, when selecting 3 second-type battery packs to power an outdoor garden lawn mower, the 3 second-type battery packs can provide a total discharge power of at least 18000w. As Figure 6 、 Figure 13 and Figure 18 shown, when selecting 2 first-type battery packs 52 and 2 second-type battery packs 53 to power an outdoor garden lawn mower, the 2 first-type battery packs 52 and the 2 second-type battery packs 53 can provide a total discharge power of at least 16000w; as Figure 7 、 Figure 8 、 Figure 14 and Figure 19 shown, when selecting 4 first-type battery packs and 1 second-type battery pack to power an outdoor garden lawn mower, the 4 first-type battery packs and the 1 second-type battery pack can provide a total discharge power of at least 15000w; as Figure 9 、 Figure 15 and Figure 20 shown, when selecting 6 first-type battery packs 52 to power an outdoor garden lawn mower, the 6 first-type battery packs 52 can provide a total discharge power of at least 12000w.

[0171] In one embodiment, the nominal voltage of the first type of battery pack 52 is equal to the nominal voltage of the second type of battery pack 53. The nominal voltage of the first type of battery pack 52 and the second type of battery pack 53 is greater than or equal to 58v. Of course, the nominal voltage of the first type of battery pack 52 or the second type of battery pack 53 can also be 62v, 72v, etc. Further, the first type of battery pack 52 includes a plurality of single-section first batteries, and the nominal voltage of each first battery is 3.7v. The second type of battery pack 53 includes a plurality of single-section second batteries, and the nominal voltage of each second battery is 3.2v. In some embodiments, the plurality of first batteries can be connected in series, parallel or series-parallel, preferably in series connection. The plurality of second batteries can be connected in series, parallel or series-parallel, preferably in series connection.

[0172] In one embodiment, the DC impedance of the first type of battery pack 52 is greater than that of the second type of battery pack 53. Further, the DC impedance of the first type of battery pack 52 is greater than or equal to 70 mΩ and less than or equal to 280 mΩ, and the DC impedance of the second type of battery pack 53 is greater than or equal to 15 mΩ and less than or equal to 48 mΩ. Preferably, the DC impedance of the first type of battery pack 52 is 70 mΩ, 150 mΩ or 280 mΩ, and the DC impedance of the second type of battery pack 53 is 15 mΩ, 30 mΩ or 48 mΩ.

[0173] In one embodiment, the first type of battery pack 52 and the second type of battery pack 53 include any one of lithium iron phosphate batteries, ternary lithium batteries, supercapacitors, graphene batteries or sodium ion batteries, and may also be other energy supply sources adapted to the present application. Different batteries can be selected according to different usage environments. For example, the low-temperature resistance of lithium iron phosphate batteries is higher than that of ternary lithium batteries, and lithium iron phosphate batteries can be preferably selected to supply energy for outdoor garden lawn mowers in low-temperature environments.

[0174] As Figure 35 and Figure 36 shown, in one embodiment, a locking structure is provided at the battery compartment 51 for locking the first type of battery pack 52 and / or the second type of battery pack 53 to the battery compartment 51. The locking structure is used to enable the first type of battery pack 52 and / or the second type of battery pack 53 to be locked in the battery compartment 51 to provide a stable power supply for the outdoor garden lawn mower. Specifically, the locking structure includes a locking member 516 and a trigger member 517. The first type of battery pack 52 and the second type of battery pack 53 are respectively provided with a first locking portion 522 and a second locking portion 532 that can be locked and engaged with the locking member 516. When the trigger member 517 is touched, the trigger member 517 can drive the locking member 516 to unlock from the first locking portion 522 or the second locking portion 532, thereby releasing the first type of battery pack 52 or the second type of battery pack 53 for replacement of the first type of battery pack 52 or the second type of battery pack 53.

[0175] As Figure 35 and Figure 37 shown, in one embodiment, a pop-up structure 58 capable of pushing the first type of battery pack or the second type of battery pack to move relative to the battery compartment is provided at the battery compartment 51; when the first type of battery pack 52 is connected to the battery compartment 51, the first type of battery pack 52 matches at least one pop-up structure 58; when the second type of battery pack 53 is connected to the battery compartment 51, the second type of battery pack 53 matches at least three pop-up structures 58.

[0176] In one embodiment, the weight of the first type of battery pack 52 is lighter than that of the second type of battery pack 53, and the weight of the second type of battery pack 53 is more than twice that of the first type of battery pack 52. In actual use, only one ejection structure 58 needs to be matched with one first type of battery pack 52 to complete the ejection action, while at least three ejection structures need to be matched with the second type of battery pack 53 to complete the ejection action.

[0177] The ejection structure 58 includes a housing 581 having a receiving cavity, a spring 582, and a moving block 583. An opening for the moving block 583 to move substantially along the ejection direction is provided at the bottom of the battery compartment 51. A limiting portion 5831 is provided to extend substantially along a direction perpendicular to the moving direction of the moving block 583. The limiting portion 5831 can form an abutment with the bottom of the battery compartment 51 in the moving direction, and the limiting portion 5831 is used to prevent the moving block 583 from detaching from the spring 582 at the opening. The spring 582 can also be replaced by other feasible elastic elements.

[0178] One end of the spring 582 is located inside the housing 581, and the other end abuts against the moving block 583. The moving block 583 can move substantially along the compression direction of the spring 582. Usually, the ejection structure 58 is provided at the bottom of the battery compartment 51. After the locking structure unlocks the first type of battery pack 52 or the second type of battery pack 53, the moving block 583 is under the elastic force of the spring 582, and pushes the first type of battery pack 52 or the second type of battery pack 53 to eject, so that the first type of battery pack 52 or the second type of battery pack 53 moves away from its original position by a certain distance for the user to pick up and place the battery pack.

[0179] In order to reduce the impact on the first type of battery pack 52 or the second type of battery pack 53 when the outdoor garden lawn mower is moving, and also to ensure the safe use of the first type of battery pack 52 and the second type of battery pack 53, a shock-absorbing structure is provided between the power supply device 5 and the main frame 1.

Specifically, the heat dissipation structure can be a heat dissipation fan or a heat sink.

[0182] The battery compartment 51 is provided with a drain hole, which can timely drain liquids such as sewage in the battery compartment 51. This can not only reduce the weight of the battery compartment 51, but also effectively prevent liquids such as sewage from polluting the battery pack, thereby avoiding affecting the usage effect and service life of the first type of battery pack 52 or the second type of battery pack 53. Usually, the drain hole is arranged at the connection between the bottom wall and the side wall of the battery compartment, which is conducive to drainage.

[0183] As Figure 35 shown, in an embodiment, the outdoor garden lawn mower further includes a battery compartment bottom plate 56 for fixing the battery compartment 51 on the main frame 1. A power management module 57 is arranged on the side of the battery compartment bottom plate 56 facing away from the battery compartment 51. Such an arrangement can save the wires used for connecting the power management module 57 and the battery pack.

[0184] In an embodiment, the power management module 57 can also be arranged between the battery compartment 51 and the battery compartment bottom plate 56.

[0185] In an embodiment, the cutting assembly 2 includes a mowing motor, and the traveling assembly 3 includes a traveling motor. The maximum output power of the mowing motor is different from the maximum output power of the traveling motor. Preferably, the output power of the mowing motor is 1200w, and the output power of the traveling motor is 1500w.
