[0124] This application performs targeted processing on battery packs with different types of temperature abnormalities and does not process battery packs with normal temperatures. Since the electricity required to process temperature abnormalities also comes from the battery pack, this setting can save electricity and improve the battery life of the battery pack.

[0125] The battery compartment is equipped with multiple temperature control components, which perform one-to-one processing on the first type of battery pack whose temperature is within the first range of values, and two-to-one processing on the second type of battery pack whose temperature is within the first range of values. In this way, temperature control can be performed according to the actual needs of the battery pack, avoiding unnecessary waste of battery pack energy.

[0126] In addition, when the temperature is in the second range, the number of temperature regulating components for processing the first type of battery pack is more than the number of battery packs inserted into the lawn mower, and at most all the temperature regulating components on the lawn mower can be used to temperature regulate the first type of battery pack; when the temperature is in the second range, the number of temperature regulating components for processing the second type of battery pack is twice or more than the number of battery packs inserted into the lawn mower, and at most all the temperature regulating components on the lawn mower can be used to temperature regulate the first type of battery pack, thereby achieving the purpose of differential and rapid temperature regulation of the first type of battery pack or the second type of battery pack, so that the first type of battery pack or the second type of battery pack can be kept within the normal range as much as possible.

[0217] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. For example, the terms "upper," "lower," "left," "right," "front," and "back" that indicate orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the device referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.

[0218] For example, when a user rides on an outdoor garden mower located on the ground, the direction the user is facing is defined as forward, the direction facing away is defined as backward, the direction to the left is defined as left, the direction to the right is defined as right, the direction close to the ground is defined as downward, and the direction away from the ground is defined as upward.

[0219] Please refer to Figures 1 and 2 for an outdoor garden lawn mower according to an embodiment of the present application, which is widely used in fields such as vegetation pruning. 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 straight direction 101 parallel to the front-rear direction. The seat is mounted 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 cutting operations, and enables the traveling assembly 3 to support the main frame 1 and related components on the main frame 1 to travel.

[0220] Specifically, the cutting assembly 2 serves as a power output element, outputting power to achieve the mowing function of the electric lawn mower. The cutting assembly 2 can be provided in two or three groups. The cutting assembly 2 is positioned below the main frame 1. In one embodiment, the cutting assembly 2 includes a cutter disc, a mowing element, and a mowing motor. The mowing element is used to cut vegetation while rotating at high speed. For example, the mowing element is a blade used to cut lawn vegetation. The cutter disc defines a mowing space for the mowing element, which is at least partially located within the mowing space. In some embodiments, the number of mowing elements can be two, and the number of mowing motors can also be two. Accordingly, the two mowing motors each drive the two mowing elements. In some embodiments, the number of mowing elements can be three, and the number of mowing motors can also be three. The three mowing motors each drive the three mowing elements. Of course, the cutting assembly 2 can also be removed from the outdoor garden mower. In some embodiments, the cutting assembly 2 can be replaced with a snow shoveling assembly or other assembly. Therefore, the outdoor garden mower can be used not only for cutting vegetation but also for other applications such as snow shoveling.

[0221] The travel assembly 3 includes travel wheels mounted on the main frame 1 and travel motors for driving the travel wheels. The travel wheels are arranged on both sides of the main frame 1 to maintain the center of gravity of the outdoor garden lawn mower within the main frame 1, thereby reducing the chance of the outdoor garden lawn mower tipping over during travel. In one embodiment, the number of travel wheels is set to four, including two front travel wheels and two rear travel wheels. The front travel wheels can be universal wheels, and the travel motors are connected to the rear travel wheels and drive the rear travel wheels to rotate. Both rear travel wheels are matched with travel motors, and the speeds of the two travel motors can be the same or different. When the user is driving the outdoor garden lawn mower straight, the speeds of the two travel motors are approximately the same. When the user is turning the outdoor garden lawn mower, the speeds of the two travel motors are different, and the outdoor garden lawn mower turns towards the side with the lower travel motor speed. In some embodiments, the diameter of the front travel wheels is smaller than that of the rear travel wheels. Of course, the number of travel wheels can also be set to three or five.

[0222] The operating assembly 4 includes a first operating lever and a second operating lever disposed on the left and right sides of the outdoor garden mower. The user manipulates the first and second operating levers to control the outdoor garden mower forward, backward, or turn. The operating assembly 4 can also be a steering wheel capable of controlling the outdoor garden mower. The present application also includes a brake assembly disposed on the front upper surface of the main frame 1, which the user can step on to control the operation of the outdoor garden mower.

[0223] Referring to Figures 38, 39, and 40, the power supply device 5 includes a first-type battery pack 52, a second-type battery pack 53, and a battery compartment 51. In some embodiments, the power supply device 5 is positioned at the rear of the outdoor lawn mower. The first-type battery pack 52 and the second-type battery pack 53 have identical electrical connectors. The first-type battery pack 52's connector includes multiple first terminal slots 521, while the second-type battery pack 53's connector includes multiple second terminal slots 531. The first and second terminal slots 521 and 531 have identical structures. The sidewalls of the battery compartment 51 are also provided with electrical connection terminals 513 capable of electrically connecting with the connectors. When the first-type battery pack 52 is mated with the battery compartment 51, the multiple first terminal slots 521 mate with the electrical connection terminals 513. When the second-type battery pack 53 is mated with the battery compartment 51, the multiple second terminal slots 531 mate with the electrical connection terminals 513, enabling the power supply device 5 to power the outdoor lawn mower and complete its intended outdoor tasks. Compared with the traditional use of fossil fuels as an energy source, the outdoor garden mower of the present application is more environmentally friendly and more in line with long-term development plans.

[0224] It should be noted that both the first type battery pack 52 and the second type battery pack 53 can be connected to the electrical connection terminal 513, without the need to set up two electrical connection terminals, making the battery pack structure more compact and simple, which is conducive to achieving a simplified design of the battery pack.

[0225] In some embodiments, the size of the first type battery pack 52 is generally set to be smaller than the size of the second type battery pack 53. In conventional settings, the capacity of the battery pack is proportional to its size, that is, the smaller the battery pack size, the smaller the capacity; the larger the battery pack size, the larger the capacity.

[0226] As shown in Figures 3 to 5, in one embodiment, the battery compartment 51 includes a first side wall and a second side wall that are arranged opposite each other. At least one pair of electrical connection terminals 513 among the multiple electrical connection terminals 513 are respectively arranged on the first side wall and the second side wall, and can be removably electrically connected to the first type battery pack 52 and / or the second type battery pack 53. In order to ensure that the electrical connection terminal 513 at a mating position of the battery compartment 51 can form an electrical connection 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 provided on the first side wall and the second side wall on opposite sides of the battery compartment 51. This arrangement allows the two electrical connection terminals 513 to be electrically connected to two first type battery packs 52, or to be electrically connected to one second type battery pack 53. Multiple pairs of electrical connection terminals 513 can also be provided to meet the need of using multiple second type battery packs 53 at the same time.

[0227] In one embodiment, the electrical connection terminal 513 includes a positive terminal and a negative terminal, and is configured to connect to an electrical connection connector of the first type battery pack 52 or the second type battery pack 53 .

[0228] In one embodiment, a first-type battery pack 52 is provided with only one electrical connector, with the positive and negative poles of the connector located on the same side, connectable to the positive and negative poles of the electrical connection terminals 513. This allows a single electrical connection terminal 513 to connect to a first-type battery pack 52 to form an electrical connection. A second-type battery pack 53 is provided with two electrical connectors located on opposite sides of the pack, one of which can connect to one of the electrical connection terminals 513 located on the opposite side, and the other can connect to the other electrical connection terminal 513 to form an electrical connection. Of course, the two electrical connection terminals of a second-type battery pack 53 can also be located on the same side.

[0229] In one embodiment, both the first type battery pack 52 and the second type battery pack 53 can power the mowing motor and the travel motor.

[0230] In a preferred embodiment, both the first type battery pack 52 and the second type battery pack 53 can be removed from the outdoor garden mower and can also be used to power other electric tools.

[0231] In a preferred embodiment, as shown in Figures 2, 3, and 11, the orthographic projections of at least one pair of electrical connection terminals 513 disposed on the first and second side walls of the battery compartment 51 at least partially overlap along a direction perpendicular to or parallel to the first straight line 101. The orthographic projections of the pairs of electrical connection terminals 513 disposed on opposite sides of the battery compartment 51, along a direction perpendicular to or parallel to the first straight line, may completely overlap, partially overlap, completely non-overlap, or a combination of at least any two of completely overlapping, partially overlapping, or completely non-overlapping. This can be adjusted based on actual needs to accommodate the design requirements of the battery compartment 51, thereby enriching the ways in which the battery compartment 51 can be connected to the battery pack, thereby improving the compatibility of the outdoor garden mower with different types of battery packs.

[0232] In another embodiment, the orthographic projections of at least one pair of electrical connection terminals 513 disposed on the first and second side walls of the battery compartment 51 do not overlap along a direction perpendicular to or parallel to the first linear direction 101. That is, the orthographic projections of at least one, more, or all of the paired electrical connection terminals 513 do not overlap along a direction perpendicular to or parallel to the first linear direction 101. The specific orthographic projections can be adjusted based on actual needs to optimize the actual use of the battery compartment 51 structure.

[0233] As shown in Figure 4 , the first-type battery pack 52 or the second-type battery pack 53 is provided with a slideway that is pluggable with the track 514, meaning that the first-type battery pack 52 or the second-type battery pack 53 share the same track 514. The slideways on the first-type battery pack 52 or the second-type battery pack 53 can be identical or different, as long as both can form a pluggable relationship with the track 514 on the battery compartment 51. Typically, a slideway and a track 514 form a set, and at least one set of slideways and slideways is provided between a battery pack and the battery compartment 51, but two or more sets may also be provided.

[0234] In one embodiment, the first type battery pack 52 and the second type battery pack 53 may also use different rails 514 respectively, as long as they are connected to the same electrical connection terminal 513 to achieve electrical connection in accordance with quick plug and unplug.

[0235] In some embodiments, in addition to using the slide groove and rail 514 to achieve pluggable installation of the first type battery pack 52 or the second type battery pack 53 into the battery compartment 51, other structures can be used to achieve the installation and coordination of the first type battery pack 52 or the second type battery pack 53 into the battery compartment 51. For example, a groove can be provided at the bottom of the first type battery pack 52 or the second type battery pack 53, and a ridge can be provided at the bottom of the battery compartment 51 to cooperate with the groove. Any structure that provides installation guidance or installation stability is acceptable.

[0236] In an exemplary embodiment, the battery compartment 51 includes a first battery compartment 511 for accommodating a first-type battery pack 52 and a second battery compartment 512 for accommodating a first-type battery pack 52 and / or a second-type battery pack 53. The first battery compartment 511 is generally smaller and can accommodate only the first-type battery pack 52, while the second battery compartment 512 is generally larger and can accommodate either the first-type battery pack 52 or the second-type battery pack 53. In one embodiment, the first battery compartment 511 and the second battery compartment 512 are isolated from each other, with the first battery compartment 511 located outside the second battery compartment 512. Preferably, the first battery compartment 511 is provided on both sides of the second battery.

[0237] As shown in Figures 6 to 9, in some embodiments, taking the battery compartment 51 structure of Figure 5 as an example, the combination of the first type battery pack 52 and the second type battery pack 53 on the outdoor garden mower includes the following: 2 first type battery packs 52 and 2 second type battery packs 53, or 4 first type battery packs 52 and 1 second type battery pack 53, or 6 first type battery packs 52.

[0238] In one embodiment, the battery compartment 51 is configured to be roughly an integral rectangular compartment structure, and the arrangement of the battery packs is shown in Figures 10-15, including the following methods: it 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.

[0239] As shown in Figures 16-20, in one embodiment, the battery compartment 51 includes a third sidewall and a fourth sidewall disposed opposite each other. At least a portion of the third sidewall of the battery compartment 51 extends away from the fourth sidewall to form a secondary compartment 515 capable of accommodating either the first-type battery pack 52 or the second-type battery pack 53. A terminal mounting seat is provided on the side of the fourth sidewall proximal to the third sidewall, which is used to receive at least the electrical connection terminal 513. Preferably, the third sidewall extends along the first linear direction 101. This configuration creates a single, integral compartment, similar to a "T"-shaped structure, which better fits the rear space of an outdoor lawn mower and effectively utilizes the rear space. Specifically, this battery compartment 51 design can accommodate three second-type battery packs 53, two second-type battery packs 53 and two first-type battery packs 52, one second-type battery pack 53 and four first-type battery packs 52, or six first-type battery packs 52.

[0240] 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.

[0241] As shown in Figures 21-26, 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 can be rectangular, elliptical, diamond-shaped, circular, or other polygonal, or can be roughly rectangular, as shown in Figure 27. The same shape can also be arranged in different combinations within the battery compartment 51, as shown in Figures 22 and 23 and Figures 24 and 25.

[0242] In one embodiment, in order to drive the outdoor garden mower, at least one first type battery pack 52 or one second type battery pack 53 is installed in the battery compartment 51 to power the outdoor garden mower.

[0243] As shown in Figure 35 , in one embodiment, a cover 54 is pivotally connected to one edge of the battery compartment 51 opening. Cover 54 is connected to the battery compartment 51 via a pivot pin, driving the opening and closing of cover 54 to switch the battery compartment 51 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 cover 54. The shape of cover 54 matches the shape of the battery compartment 51 opening and is not limited to the structure of cover 54 shown in Figure 24 ; it can also be rectangular, circular, or other shapes.

[0244] The battery compartment 51 includes an inwardly concave groove, and the first type battery pack 52 or the second type 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 .

[0245] In one embodiment, the first linear direction 101 intersects the second linear direction 102. Furthermore, the angle between the first linear direction 101 and the second linear direction 102 is less than 60 degrees. Preferably, the angle between the first linear direction 101 and the second linear direction 102 is 30 degrees, 45 degrees, or 59 degrees.

[0246] In one embodiment, the first linear direction 101 and the second linear direction 102 are parallel to each other, that is, the groove also extends along the first linear direction 101 .

[0247] In one embodiment, the first linear direction 101 and the second linear direction 102 are perpendicular to each other.

[0248] In one embodiment, the first type battery pack 52 and the second type battery pack 53 are inserted into the battery compartment 51 at different angles, or the insertion angles of the first type battery packs 52 are different from each other, or the insertion angles of the second type battery packs 53 are different from each other.

[0249] Multiple first-type battery packs 52 or multiple second-type battery packs 53 can be assembled with the outdoor garden mower in a manner perpendicular to the first linear direction 101. Specifically, the multiple first-type battery packs 52 or multiple second-type battery packs 53 can be arranged in parallel at the same height, as shown in FIG28; or, the multiple first-type battery packs 52 or multiple second-type battery packs 53 can be arranged at different heights, similar to a stepped arrangement, as shown in FIG29; or, the multiple first-type battery packs 52 or multiple second-type battery packs 53 can be staggered in a low-high-low arrangement, as shown in FIG30. Setting the battery pack installation heights to different heights facilitates access to the battery packs.

[0250] Furthermore, multiple first-type battery packs 52 or multiple second-type battery packs 53 can also be assembled with the outdoor garden mower in a form of an angle with the first straight direction 101, that is, multiple first-type battery packs 52 or multiple second-type battery packs 53 are arranged in an oblique and staggered manner.

[0251] As shown in FIG. 31 , a plurality of first-type battery packs 52 or a plurality of second-type battery packs 53 may also be assembled in the battery compartment 51 in a stacked manner in the vertical direction.

[0252] As shown in Figures 32 and 33, taking the second type battery pack 53 as an example, looking down at the outdoor garden mower from above the battery compartment 51, the second type battery pack 53 has different heights in the first straight line direction 101. Preferably, it is arranged in a stepped form or in a high-low-high form in the first straight line direction.

[0253] In one embodiment, the first type battery pack 52 and the second type battery pack 53 are not only arranged on the rear side of the outdoor garden mower, but 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.

[0254] In one embodiment, the volume ratio of the first type battery pack 52 to the second type battery pack 53 is 0.01-0.9. Preferably, the volume ratio of the first type battery pack 52 to the second type battery pack 53 is 0.2.

[0255] In one embodiment, the length, width, and height of the first type battery pack 52 are: 160mm-200mm, 110mm-130mm, and 150mm-180mm, and the length, width, and height of the second type battery pack 53 are: 360mm-390mm, 160mm-190mm, and 200mm-230mm.

[0256] In a preferred embodiment, the length, width, and height of the first-type battery pack 52 are 188.5 mm, 124 mm, and 160 mm, while the length, width, and height of the second-type battery pack 53 are 371 mm, 179 mm, and 221 mm. This arrangement allows the first-type battery pack 52 and the second-type battery pack 53 to better utilize the space in the battery compartment 51, eliminating wasted space and preventing the larger second-type battery pack 53 from being inconveniently placed in the battery compartment 51 due to limited space.

[0257] As shown in Figure 34, in one embodiment, the battery compartment 51 is arranged at the rear of the outdoor garden lawn mower, and the distance L from the lowest point of the battery compartment 51 to the ground is at least 380 mm. This arrangement makes it difficult for the outdoor garden lawn 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 vehicle body to the rear walking wheel of the outdoor garden lawn mower and the ground is α. The larger the angle α, the lower the probability of the battery compartment 51 touching the ground. The higher height of the battery compartment 51 also helps to reduce the degree of bending when the user takes and puts the battery pack, optimizing the user experience.

[0258] In one embodiment, the energy density of the first-type battery pack 52 is greater than or equal to 200wh / kg and less than or equal to 500wh / kg, and the energy density of the second-type battery pack 53 is greater than or equal to 100wh / kg and less than or equal to 250wh / kg. Preferably, the energy density of the first-type battery pack 52 is 200wh / kg, 300wh / kg, or 500wh / kg, and the energy density of the second-type battery pack 53 is 100wh / kg, 120wh / kg, or 250wh / kg.

[0259] In one embodiment, the capacity of the first-type battery pack 52 is greater than or equal to 90 Wh and less than or equal to 1000 Wh, and the capacity of the second-type battery pack 53 is greater than or equal to 1000 Wh. Preferably, the capacity of the first-type battery pack 52 is 90 Wh, 300 Wh, or 1000 Wh, and the capacity of the second-type battery pack 53 is 1000 Wh, 13000 Wh, or 24000 Wh. When the area to be mowed is small, only the first-type battery pack 52 can be used to power the outdoor lawn mower. The first-type battery pack 52 is smaller and therefore lighter, reducing the burden on the user when carrying the battery pack. When the area to be mowed is medium, the first-type battery pack 52 and the second-type battery pack 53 can be used in combination to power the outdoor lawn mower. When the area to be mowed is large, multiple second-type battery packs 53 can be used to power the outdoor lawn mower, thereby increasing the endurance of the outdoor lawn mower and eliminating the need for repeated charging or battery replacement.

[0260] In some embodiments, as shown in Figures 12 and 17, when three second-type battery packs are selected to power an outdoor garden mower, the three second-type battery packs can provide a total discharge capacity of at least 20,000 Wh. As shown in Figures 6, 13, and 18, when two first-type battery packs 52 and two second-type battery packs 53 are selected to power an outdoor garden mower, the two first-type battery packs 52 and two second-type battery packs 53 can provide a total discharge capacity of at least 15,000 Wh. As shown in Figures 7, 8, 14, and 19, when four first-type battery packs and one second-type battery pack are selected to power an outdoor garden mower, the four first-type battery packs and one second-type battery pack can provide a total discharge capacity of at least 10,000 Wh. As shown in Figures 9, 15, and 20, when six first-type battery packs 52 are selected to power an outdoor garden mower, the six first-type battery packs 52 can provide a total discharge capacity of at least 6,000 Wh.

[0261] In one embodiment, the electrical connection terminal 513 of the outdoor garden mower is further provided with an identification terminal for identifying the first type battery pack 52 and the second type battery pack 53. The type of the battery pack is identified by the identification terminal to adjust the working power of the outdoor garden mower.

[0262] In one embodiment, the discharge power of the first type battery pack 52 is greater than or equal to 2000W and less than or equal to 4350W, and the discharge power of the second type battery pack 53 is greater than or equal to 3500W and less than or equal to 6960W. Preferably, the discharge power of the first type battery pack 52 is 2000W, 3000W, or 4350W, and the discharge power of the second type battery pack 53 is 3500W, 5000W, or 6960W. The first type battery pack 52 is suitable for small-scale vegetation cutting operations and is easy to carry and disassemble. The second type battery pack 53 is suitable for large-scale vegetation cutting operations and has a long battery life, eliminating the need for repeated charging or mid-process battery pack replacement.

[0263] In some embodiments, as shown in Figures 12 and 17, when three second-type battery packs are selected to power an outdoor garden mower, the three second-type battery packs can provide a total discharge power of at least 18,000W. As shown in Figures 6, 13, and 18, when two first-type battery packs 52 and two second-type battery packs 53 are selected to power an outdoor garden mower, the two first-type battery packs 52 and two second-type battery packs 53 can provide a total discharge power of at least 16,000W. As shown in Figures 7, 8, 14, and 19, when four first-type battery packs and one second-type battery pack are selected to power an outdoor garden mower, the four first-type battery packs and one second-type battery pack can provide a total discharge power of at least 15,000W. As shown in Figures 9, 15, and 20, when six first-type battery packs 52 are selected to power an outdoor garden mower, the six first-type battery packs 52 can provide a total discharge power of at least 12,000W.

[0264] In one embodiment, the nominal voltage of the first type battery pack 52 is equal to the nominal voltage of the second type battery pack 53. The nominal voltage of the first type battery pack 52 and the nominal voltage of the second type battery pack 53 are greater than or equal to 58V. Of course, the nominal voltage of the first type battery pack 52 or the nominal voltage of the second type battery pack 53 can also be 62V or 72V, etc. Furthermore, the first type battery pack 52 includes a plurality of single-cell first batteries, each of which has a nominal voltage of 3.7V, and the second type battery pack 53 includes a plurality of single-cell second batteries, each of which has a nominal voltage of 3.2V. In some embodiments, the plurality of first batteries can be connected in series, in parallel, or in series and parallel, preferably in series, and the plurality of second batteries can be connected in series, in parallel, or in series and parallel, preferably in series.

[0265] In one embodiment, the DC impedance of the first-type battery pack 52 is greater than the DC impedance of the second-type battery pack 53. Furthermore, the DC impedance of the first-type 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 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 battery pack 52 is 70 mΩ, 150 mΩ, or 280 mΩ, and the DC impedance of the second-type battery pack 53 is 15 mΩ, 30 mΩ, or 48 mΩ.

[0266] In one embodiment, the first type battery pack 52 and the second type battery pack 53 include any one of a lithium iron phosphate battery, a ternary lithium battery, a supercapacitor, a graphene battery, or a sodium ion battery, or other energy supply sources compatible with the present application. Different batteries can be selected based on different usage environments. For example, lithium iron phosphate batteries have higher low-temperature resistance than ternary lithium batteries, so lithium iron phosphate batteries are preferred for powering outdoor garden mowers in low-temperature environments.

[0267] As shown in Figures 35 and 36, in one embodiment, the battery compartment 51 is provided with a locking structure for locking the first-type battery pack 52 and / or the second-type battery pack 53 to the battery compartment 51. The locking structure is used to lock the first-type battery pack 52 and / or the second-type battery pack 53 within the battery compartment 51, thereby providing a stable power source for the outdoor garden mower. Specifically, the locking structure includes a locking member 516 and a trigger member 517. The first-type battery pack 52 and the second-type battery pack 53 are respectively provided with a first locking portion 522 and a second locking portion 532 that can lock with the locking member 516. When the trigger member 517 is triggered, the trigger member 517 can drive the locking member 516 to unlock the first locking portion 522 or the second locking portion 532, thereby releasing the first-type battery pack 52 or the second-type battery pack 53, so that the first-type battery pack 52 or the second-type battery pack 53 can be replaced.

[0268] As shown in Figures 35 and 37, in one embodiment, a pop-up structure 58 is provided at the battery compartment 51, which is capable of pushing the first type battery pack or the second type battery pack to move relative to the battery compartment; when the first type battery pack 52 is connected to the battery compartment 51, the first type battery pack 52 matches at least one pop-up structure 58; when the second type battery pack 53 is connected to the battery compartment 51, the second type battery pack 53 matches at least three pop-up structures 58.

[0269] In one embodiment, the weight of the first type battery pack 52 is lighter than the weight of the second type battery pack 53, and the weight of the second type battery pack 53 is more than twice the weight of the first type battery pack 52. In actual use, one first type battery pack 52 only needs to match one pop-up structure 58 to complete the pop-up action, while the second type battery pack 53 needs to match at least three pop-up structures to complete the pop-up action.

[0270] The ejection structure 58 comprises a housing 581 with a receiving cavity, a spring 582, and a movable block 583. The bottom of the battery compartment 51 is provided with an opening for the movable block 583 to move approximately in the ejection direction. A limiter 5831 is provided extending approximately perpendicular to the direction of movement of the movable block 583. The limiter 5831 abuts the bottom of the battery compartment 51 in the direction of movement and prevents the movable block 583 from separating from the spring 582 at the opening. The spring 582 can also be replaced with other suitable elastic elements.

[0271] One end of the spring 582 is located inside the shell 581, and the other end abuts against the moving block 583. The moving block 583 can move roughly along the compression direction of the spring 582. Normally, the pop-up structure 58 is set at the bottom of the battery compartment 51. When the locking structure unlocks the first type battery pack 52 or the second type battery pack 53, the moving block 583 pushes the first type battery pack 52 or the second type battery pack 53 to pop out under the elastic force of the spring 582, so that the first type battery pack 52 or the second type battery pack 53 moves a certain distance away from its original position, so that the user can take and place the battery pack.

[0272] To reduce the impact of the first-type battery pack 52 or the second-type battery pack 53 on the outdoor lawn mower while in motion, and to ensure the safe use of the first-type battery pack 52 and the second-type battery pack 53, a shock-absorbing structure is provided between the power supply unit 5 and the main frame 1. Specifically, the shock-absorbing structure is provided between the battery compartment bottom plate 56 and the main frame 1, and the shock-absorbing structure may be a compression spring or an elastic sheet.

[0273] In order to increase the multifunctional use of the battery compartment 51, at least part of the battery compartment 51 can be configured as a storage compartment for storing items other than the first type battery pack 52 or the second type battery pack 53, and the storage compartment can store tools or other sundries.

[0274] The battery compartment 51 is provided with a heat dissipation structure for dissipating heat from the first type battery pack 52 and / or the second type battery pack 53, effectively preventing the first type battery pack 52 or the second type battery pack 53 from overheating and thereby reducing the charging and discharging efficiency. Specifically, the heat dissipation structure may be a cooling fan or a heat sink.

[0275] The battery compartment 51 is provided with a drainage hole to promptly drain liquids such as sewage from the battery compartment 51. This not only reduces the weight of the battery compartment 51 but also effectively prevents the sewage and other liquids from contaminating the battery pack, thereby preventing the performance and service life of the first type battery pack 52 or the second type battery pack 53 from being affected. Typically, the drainage hole is provided at the junction of the bottom wall and the side wall of the battery compartment to facilitate drainage.

[0276] As shown in Figure 35, in one embodiment, the outdoor garden lawn mower also includes a battery compartment base plate 56, which is used to fix the battery compartment 51 on the main frame 1. A power management module 57 is provided on the side of the battery compartment base plate 56 facing away from the battery compartment 51. Such a setting can save the use of wires used to connect the power management module 57 and the battery pack.

[0277] In one embodiment, the power management module 57 may also be disposed between the battery compartment 51 and the battery compartment bottom plate 56 .

[0278] In one 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.

[0281] FIG41 is a graph showing the relationship between the output power and torque of the mowing motor, and FIG42 is a graph showing the relationship between the output power and torque of the walking motor.

[0282] As shown in Figure 43, the power management module 57 includes a control unit, a charging unit, and a discharging unit. The control unit controls the charging and discharging of the first and second battery packs 52, 53, respectively, and controls the first and second battery packs 52, 53 to power the mowing motor, the travel motor, or other power-consuming components. The control unit can withstand a maximum power of 2500W.

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.

[0294] 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.

[0295] 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 and provide power for the above-mentioned functional components such as snow shoveling, snow sweeping, and snow blowing.

[0296] 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.

[0297] In one embodiment, the number of running wheels is set to four, including two front running wheels 601 and two rear running wheels 602.

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.

[0298] In one embodiment, referring to Figures 2, 3, and 4, a power supply device 200 is used to power at least outdoor work equipment. The power supply device 200 includes a battery compartment 201. A first-type battery pack 205 or a second-type battery pack 206, or both, can be installed in the battery compartment 201. The first-type battery pack 205 and the second-type battery pack 206 can each be detachably installed in the battery compartment 201.

[0299] 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.

[0300] Referring to Figures 45, 46, and 47, the battery compartment 201 is also provided with multiple temperature control components 203. These components 203 utilize electrical energy from the battery packs on the outdoor equipment to control the temperature. These components 203 are configured to control the temperature of the first type battery pack 205 and / or the second type battery pack 206. In one embodiment, temperature control includes both heating and cooling. In this application, the temperature of the first type battery pack 205 and / or the second type battery pack 206 can be increased or decreased based on actual needs.

[0301] 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.

[0302] 45 , 46 and 47 , specifically, when the first type battery pack 205 and the second type battery pack 206 need to be cooled, the temperature control component 203 is an airflow generator 2031 capable of generating airflow, specifically a cooling fan, for cooling the first type battery pack 205 and the second type battery pack 206 .

[0303] 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.

[0304] As shown in Figures 45 and 47, 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.

[0305] 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.

[0306] 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.

[0307] 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.

[0308] 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.

[0309] 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.

[0310] 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.

[0311] 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.

[0312] As shown in Figures 46 and 47, 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.

[0313] 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.

[0314] 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.

[0315] 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. Two temperature control components 203 are required to meet the heat dissipation or heating requirements of one second-type battery pack 206. The second-type battery pack 206 whose temperature is within the normal range is not temperature-controlled. 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 is saved, and the battery pack's endurance is improved.

[0316] 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.

[0317] As shown in Figures 45 to 51, 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 located 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.

[0318] As shown in Figures 48 and 49, 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 form 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.

[0319] In one embodiment, the offset distance between the mounting positions 224 arranged in pairs and the other mounting positions 224 is 20 mm to 40 mm, and preferably the offset distance is 20 mm, 30 mm and 40 mm.

[0320] As shown in FIG. 48 to FIG. 51 , further, an electrical connection terminal 220 is provided on each installation position, so that at least one pair of electrical connection terminals 220 is staggered with other electrical connection terminals 220 .

[0321] As shown in Figures 48 to 51, 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 of 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.

[0322] As shown in Figures 45 to 47 , the battery compartment 201 has an opening for inserting and removing the first-type battery pack 205 and / or the second-type battery pack 206. A compartment cover 202 is provided corresponding to this opening. The compartment cover 202 is configured to cover the opening of the battery compartment 201, forming a relatively closed cavity. 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.

[0323] As shown in Figures 48 to 51, multiple airflow exchange parts 204 are provided on the two corresponding side panels 216 of the battery compartment 201, and one temperature control component 203 is matched with one airflow exchange part 204. The temperature control component 203 can exhaust and intake air into the battery compartment 201 through the corresponding airflow exchange part 204.

[0324] As shown in Figures 48 to 51, in one embodiment, when the internal temperature of the first type battery pack 205 is within a first range of values, 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 to dissipate heat from the first type battery pack.

[0325] As shown in Figures 48 to 51, 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; they can also exhaust air to the outside of the battery compartment 201 at the same time; they can also partially blow air into the battery compartment 201 and partially exhaust air to the outside of the battery compartment 201.

[0326] As shown in Figures 46 to 51, 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 unit 204. Preferably, the two temperature control assemblies 203 are respectively disposed on two corresponding side panels 216 of the battery compartment 201, and the electrical 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 of the two side panels 216, so that the temperature control assemblies 203 can also dissipate heat generated when the electrical connection terminals 220 and the electrical connection terminals 2061 come into contact.

[0327] Furthermore, when the internal temperature of the second type battery pack 206 is within the second range value, multiple temperature control components 203 can simultaneously blow air or exhaust (external air extraction) the second type battery pack 206 loaded into the battery compartment 201 through the airflow exchange unit 204, or at least one blows air inward and at least one exhausts air outward (external air extraction).

[0328] 45 , 47 , 57 , and 58 , to enhance heat dissipation or temperature increase, in one embodiment, the first type battery pack 205 is provided with a first vent 2052 and 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 regulating the temperature of the first type battery pack 205 or the second type battery pack 206 , air can be discharged through the first vent 2052 and introduced through the second vent 2053 , removing heat from the first type battery pack 205 , rapidly dissipating heat from the first type battery pack 205 to a normal temperature range. Alternatively, air can be introduced through the first vent 2052 and introduced through the second vent 2053 , heating the first type battery pack 205 , rapidly raising the temperature within the first type battery pack 205 to a normal temperature range.

[0329] Referring to Figures 45, 47, 55, 56, 59, and 60, in one embodiment, a third vent 2062 and a fourth vent 2603 are provided on the second-type battery pack 206. Preferably, the third vent 2062 and the fourth vent 2603 are provided at opposite 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. Providing two airflow exchange portions 204 to ventilate and dissipate heat for one second-type battery pack 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.

[0330] 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.

[0331] 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 a fifth vent 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 fifth vent 2064 is provided on both sides of the power terminal on the battery pack.

[0332] As shown in Figure 61, 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 control components 203 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 control 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 control 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.

[0333] 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.

[0334] In one embodiment, the temperature control assembly 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, the 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, the airflow generator 2031 continues to dissipate heat from the power supply unit.

[0335] In one embodiment, 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 temperature of the normal operation 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.

[0336] 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.

[0337] As shown in Figures 45 and 61, in one embodiment, the power supply unit includes a first-type battery pack 205. When the number of first-type battery packs 205 having an internal temperature 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 an internal temperature 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.

[0338] 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.

[0339] 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.

[0340] 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 .

[0341] As shown in Figures 46 and 61, 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 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 with 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.

[0342] 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.

[0343] 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.

[0344] 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.

[0345] Please refer to Figures 61 and 83 at the same time. In one embodiment, the temperature detection module within the battery pack (first type battery pack 205 and / or second type battery pack 206) detects the temperature inside the battery pack and transmits the detected temperature inside the battery pack to the power management device 219. The power management device 219 determines that the detected temperature exceeds the threshold and performs corresponding processing.

[0346] In the charging state, when the detected temperature inside the battery pack is higher than 35°C, the power management device 219 turns on the airflow generator 2031 (cooling fan) corresponding to the battery pack. The airflow generator 2031 generates airflow and blows heat to the battery pack through the airflow exchange unit 204 on the battery compartment 201. When the detected temperature inside the battery pack is less than or equal to 30°C, the power management device 219 turns off the airflow generator 2031 corresponding to the battery pack to save energy. This process is repeated to query and judge the status of each battery pack in turn.

[0347] In the discharge state: when the detected temperature inside the battery pack is higher than 45°, the power management device 219 turns on the airflow generator 2031 (cooling fan) corresponding to the battery pack, and the airflow generator 2031 generates airflow and blows air to dissipate heat to the battery pack through the airflow exchange part 204 on the battery compartment 201; when the detected temperature inside the battery pack is less than or equal to 40°, the power management device 219 turns off the airflow generator 2031 corresponding to the battery pack.

[0348] When the feedback signal of the airflow generator 2031 is in a protection state (the airflow generator 2031 is in a short circuit, overcurrent, overtemperature, communication abnormality, etc.), the power management device 219 turns off the airflow generator 2031 and reports the specific situation of the protection state to the vehicle management module.

[0349] Please refer to Figures 61 and 84 at the same time. In another embodiment, the temperature detection module inside the battery pack (first type battery pack 205 and / or second type battery pack 206) detects the temperature inside the battery pack and transmits the detected temperature inside the battery pack to the power management device 219. The power management device 219 determines that the detected temperature exceeds the threshold and performs corresponding processing.

[0350] In the charging state, when the detected temperature inside the battery pack is higher than 35°, the power management device 219 turns on all the airflow generators 2031 on the battery compartment 201 for cooling the battery pack, and the airflow generators 2031 generate airflow and blow air to dissipate heat to the battery pack through the airflow exchange part 204 on the battery compartment 201; when the detected temperature inside the battery pack is less than or equal to 30°, the power management device 219 turns off all the airflow generators 2031 on the battery compartment 201 to save the loss of electric energy by the airflow generators 2031, thereby saving the electric energy of the battery pack.

[0351] In the discharge state: when the detected temperature inside the battery pack is higher than 45°, the power management device 219 turns on all the airflow generators 2031 on the battery compartment 201 for cooling the battery pack, and the airflow generators 2031 generate airflow and blow air to dissipate heat to the battery pack through the airflow exchange part 204 on the battery compartment 201; when the detected temperature inside the battery pack is less than or equal to 40°, the power management device 219 turns off all the airflow generators 2031 on the battery compartment 201 to save the loss of electric energy by the airflow generators 2031, thereby saving the electric energy of the battery pack.

[0352] When the feedback signal of the airflow generator 2031 is in a protection state (the airflow generator 2031 is in a short circuit, overcurrent, overtemperature, communication abnormality, etc.), the power management device 219 turns off the airflow generator 2031 and reports the specific situation of the protection state to the vehicle management module.

[0353] Referring to Figures 61 and 85 , in another embodiment, multiple battery packs are grouped together, with multiple groups provided. In the charging state, when the detected temperature within one or more battery packs in a group exceeds 35°C, the power management device 219 activates the multiple airflow generators 2031 corresponding to the group. The multiple airflow generators 2031 generate airflow, which dissipates heat from the battery packs via the airflow exchange unit 204 on the battery compartment 201. When the detected temperature within the battery packs is less than or equal to 30°C, the power management device 219 deactivates all airflow generators 2031 in the group, thereby reducing power consumption by the airflow generators 2031 and conserving energy in the battery packs.

[0354] In the discharge state: when the temperature inside a single or multiple battery packs in the detected group is higher than 45°, the power management device 219 turns on multiple airflow generators 2031 matching the corresponding group, and the multiple airflow generators 2031 operate to generate airflow, and blow air to dissipate heat to the battery pack through the airflow exchange part 204 on the battery compartment 201; when the detected temperature inside the battery pack is less than or equal to 40°, the power management device 219 turns off all the airflow generators 2031 in the group to save the loss of electric energy by the airflow generator 2031, thereby saving the electric energy of the battery pack.

[0355] When the feedback signal of the airflow generator 2031 is in a protection state (the airflow generator 2031 is in a short circuit, overcurrent, overtemperature, communication abnormality, etc.), the power management device 219 turns off the airflow generator 2031 and reports the specific situation of the protection state to the vehicle management module.

[0356] In one embodiment, when the battery pack is used for discharging, no matter how many battery packs are loaded into the battery compartment 201 , as long as the battery packs are loaded into the battery compartment 201 , all the electric fans in the battery compartment 201 are operated to dissipate heat from the battery packs.

[0357] In another embodiment, when the battery packs in the battery compartment 201 are charged, no matter how many battery packs are in the battery compartment 201, as long as the charging gun is inserted into the charging connector 218 to charge the battery packs in the battery compartment 201, all electric fans in the battery compartment 201 will start running to dissipate heat for the battery packs.

[0358] As shown in Figures 48 and 54, 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, and a heater fixed to the mounting bracket 2032. When the mounting bracket 2032 is installed and mated 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 from 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 via 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.

[0359] 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.

[0360] As shown in Figures 48 to 51, 53 and 54, 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.

[0361] As shown in Figures 44, 46 and 55, in one embodiment, the present application includes a walking component 600 for supporting the walking of outdoor work equipment; a power supply device 200, the power supply device 200 includes: a battery compartment 201, a cooling fan is provided on the battery compartment 201, and an airflow is generated when the cooling fan is running; a battery pack, which is detachably assembled in the battery compartment 201, and the battery pack includes a battery shell 2065 and a plurality of battery cells 2068 located in the battery shell 2065.

[0362] As shown in Figures 55 and 56, in one embodiment, the battery shell 2065 is a rectangular structure, and the battery shell 2065 includes a first shell 2067 perpendicular to the axial direction of the battery cell 2068 and a second shell 2066 parallel to the axial direction of the battery cell 2068. The first shell 2067 and the second shell 2066 are in a vertical relationship. The first shell 2067 is provided with a first air hole, and the second shell 2066 is provided with a second air hole. The airflow generated by the operation of the cooling fan can enter the battery shell 2065 through the first air hole, and the airflow entering the battery shell 2065 flows through the battery cell 2068 and is discharged through the second air hole. The airflow enters the battery shell 2065 through the first air hole and then flows through the battery cell 2068 and is then discharged through the second air hole. In this way, the heat generated by the battery cell 2068 can be taken away, thereby achieving the purpose of cooling the entire battery pack, thereby ensuring that the battery pack can be charged or discharged within a suitable temperature range, achieving a better charging or discharging effect.

[0363] As shown in Figures 56, 59 and 60, in one embodiment, the battery pack may be a second type battery pack 206, the first air hole is the fifth ventilation hole 2064, and the second air hole is the third ventilation hole 2062 or the fourth ventilation hole 2063.

[0364] In one embodiment, the air inlet direction of the first air hole is perpendicular to the air outlet direction of the second air hole.

[0365] As shown in Figure 56, in order to increase the air intake per unit time, the number of first air holes set on the first shell 2067 can be multiple. In one embodiment, there are two first shells 2067 and they are respectively on both sides of the battery shell 2065. There are two first air holes on each side of the first shell 2067. Each first air hole is composed of multiple honeycomb holes. The setting of multiple honeycomb holes can prevent larger debris from entering the battery shell 2065 while ensuring air intake.

[0366] As shown in Figures 48 to 51, 55, and 56, in one embodiment, an airflow exchange portion 204 is provided on the battery compartment 201, and the blowing direction of the cooling fan is the same as the direction of the airflow flowing through the airflow exchange portion 204 and the direction of the airflow flowing through the second air holes. In one embodiment, the blowing direction of the cooling fan is the same as the direction of the airflow flowing through the airflow exchange portion 204 and the direction of the airflow flowing through the second air holes and is aligned on the same straight line. This arrangement allows the airflow entering the battery housing 2065 through the first air holes to flow around the battery cells 2068 and then exit the battery housing 2065 through the second air holes. The airflow exiting the battery housing 2065 then exits the battery compartment 201 through the airflow exchange portion 204. Utilizing this airflow, the hot air inside the battery pack is discharged from the battery compartment 201.

[0368] In one embodiment, when the battery pack is loaded into the battery compartment 201 and the cooling fan is running, the cooling fan is controlled to draw air from the battery compartment 201 and exhaust it to the outside. The multiple first air holes on both sides of the battery shell 2065 are used for air intake. The air flow entering the battery shell 2065 bypasses the battery cells 2068 in the battery shell 2065, and the hot air near the battery cells 2068 is taken away by the flowing air flow. At this time, the flowing hot air is discharged from the battery shell 2065 through the second air holes at both ends of the battery shell 2065, and then the hot air is discharged separately through the air flow exchange parts 204 on the two oppositely arranged side panels 216, thereby achieving the purpose of cooling the battery pack.

[0369] As shown in Figures 45 to 47, in one embodiment, a compartment cover 202 is provided at the opening of the battery compartment 201 of the present application, and a gap is formed between the battery compartment 201 and the compartment cover 202.

[0370] Please refer to Figures 45 to 47, Figure 62, Figure 68 and Figure 69 at the same time. In one embodiment, the outdoor working equipment of the present application also includes a battery compartment 201 having an opening, and the battery compartment 201 also includes a bottom plate and a plurality of side panels 216 arranged around the bottom plate, and at least one side panel 216 is provided with a first terminal; the battery pack has a second terminal, and the battery pack is configured to be detachably assembled in the battery compartment 201 along the opening.

In a specific embodiment, a cooling fan is provided on the battery compartment 201 of the energy source system of the present application, and an air flow is generated when the cooling fan is in operation; the battery pack is detachably assembled in the battery compartment 201, and the battery pack includes a battery shell 2065 and a plurality of battery cells 2068 located in the battery shell 2065; the battery shell 2065 includes a first shell 2067 perpendicular to the axial direction of the battery cell 2068 and a second shell 2066 parallel to the axial direction of the battery cell 2068, and a first air hole is provided on the first shell 2067, and a second air hole is provided on the second shell 2066; the air flow generated by the operation of the cooling fan can enter the battery shell 2065 through the first air hole, and the air flow entering the battery shell 2065 flows through the battery cell 2068 and is discharged through the second air hole, so that the hot air inside the battery pack can be discharged, thereby realizing the heat dissipation of the battery pack.

[0404] In one embodiment, an airflow exchange portion 204 is provided on the battery compartment 201 of the energy source system of the present application. The blowing direction of the cooling fan is the same as the airflow direction flowing through the airflow exchange portion 204 and the airflow direction flowing through the second air hole and is on the same straight line. The battery pack gas can be directly discharged to the outside or blown inward. The airflow path is short and does not require detours, thereby improving the heat dissipation efficiency of the battery pack.

[0405] In one embodiment, the battery compartment 201 of the energy source system of the present application includes two opposing side panels 216, each of which is equipped with a cooling fan. The cooling fans on one side panel 216 correspond to the cooling fans on the other side panel 216. Second air holes are provided on the second housing 2066 at both ends of the battery housing 2065, perpendicular to the axial direction of the battery cells 2068. Airflow exchange portions 204 are also provided on the two opposing side panels 216. When the battery pack is installed in the battery compartment 201, the second air holes correspond to the airflow exchange portions 204.

[0406] In one embodiment, the battery packs that can be loaded into the battery compartment of the energy source system include a first type battery pack 205 and a second type battery pack 206 .

[0407] In one embodiment, the cooling fan for dissipating heat from the battery pack is installed only on a single side panel 216 of the battery compartment 201. In one embodiment, the cooling fan on a single side panel 216 can simultaneously blow air into the battery compartment 201, exhaust air to the outside, or partially exhaust air to the outside of the battery compartment 201 and partially blow air into the battery compartment 201. In one embodiment, three or six cooling fans are installed on a single side panel 216 of the battery compartment 201, but other numbers of cooling fans are also possible, depending on actual usage requirements.

[0408] As shown in Figures 44, 63 and 64, 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 configured for a user to sit on; a walking assembly 600 configured to support the walking of the outdoor work equipment, and the walking assembly 600 includes a front walking wheel 601 and a rear walking wheel 602; a power output assembly 500 is configured to perform outdoor work; the power supply device 200 is configured to supply power to the outdoor work equipment; the frame 100 includes: a first bearing part 101 is at least configured to carry the seat 400; a second bearing part 103 is at least configured to carry the power supply device 200; wherein, the heights of the first bearing part 101 and the second bearing part 103 are different.

[0409] As shown in FIG44 , FIG63 and FIG64 , in one embodiment, the vehicle frame 100 is configured to have 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.

[0410] As shown in Figures 44, 63 and 64, 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, and the rear portion of the frame 100 is used to carry a power supply device 200; when the height of the second load-bearing portion 103 is lower than the height of the first load-bearing portion 101, it is beneficial to lower the center of gravity of the entire outdoor working equipment, making the outdoor working equipment more stable during operation.

[0411] In addition, when the upper height is limited, the rear part of the frame 100 where the power supply device 200 is installed is designed to be sunken. In this way, the volume of the battery compartment 201 of the power supply device 200 can be increased to a greater extent within the limited space, so that the battery compartment 201 can accommodate a larger battery pack with a large capacity, thereby improving the endurance of the outdoor work equipment.

[0412] As shown in FIG63 , 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.

[0413] As shown in Figure 64, in one embodiment, a power fixture 116 is provided on the vehicle frame 100. The power fixture 116 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 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 opening of the battery compartment 201 can tilt toward the rear of the outdoor work equipment. The tilted opening of the battery compartment 201, which is tilted toward the rear of the outdoor equipment, facilitates access to the battery pack when replacing it. The battery packs in this embodiment include the aforementioned first-type battery pack 205 and second-type battery pack 206.

[0414] 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.

[0415] As shown in Figures 44 and 63, 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.

[0416] 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.

[0417] As shown in Figures 44, 63 and 64, the second bearing portion 103 is provided with a hook 104 for towing outdoor work equipment. In the up and down directions, the distance between the hook 104 and the axis of the rear running wheel 602 is 200mm to 380mm. In the up and down directions, 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.

[0418] As shown in Figure 63, 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°.

[0419] 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.

[0420] As shown in Figure 20, in 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.

[0421] 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.

[0422] 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.

[0423] 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.

[0424] As shown in Figures 65 and 71 to 75, in one embodiment, the outdoor work equipment of the present application includes a frame 100; a power supply device 200 is disposed on the frame 100, at least for supplying power to the outdoor work equipment; a power management device 219 is disposed below the power supply device 200 and is at least for controlling the charging or discharging of the power supply device 200; and a protective cover 106 is disposed below the power supply 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 disposed below the power supply device 200 and is protected by the protective cover 106 to prevent damage to the power management device 219 caused by liquids, hard objects, etc. Since the power management device 219 generates heat during operation, the first through hole 108 and the second through hole 110 are provided on the protective cover 106 in the present application to dissipate heat from the power management device 219.

[0425] As shown in Figures 44 and 73 to 74, the cutting component 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 component. When the outdoor working equipment moves forward and cuts vegetation, debris and other impurities will be thrown backward, and some debris will enter the protective cover 106 through the first through hole 108 or the second through hole 110. Over time, it will cause accumulation and affect the heat dissipation effect of the power management device 219.

[0426] To address the above-mentioned issues, in one embodiment of the present application, a portion of the lower surface of the protective cover 106, 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 can flow out of the protective cover 106 through the second through-hole 110 under the action of negative pressure. This ensures the 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.

[0427] As shown in FIG73 , in one embodiment, the angle α1 formed 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 differential generated, the better the negative pressure effect generated at the second through-hole 110, and the better the effect of debris discharge.

[0428] As shown in FIG74 , in one embodiment, the hole area of ​​the first through hole 108 is 60 mm 2 to 80 mm 2 , and the hole area of ​​the first through hole 108 is preferably 60 mm 2 , 70 mm 2 and 80 mm 2 .

[0429] As shown in Figure 74, the area of ​​the second through hole 110 is 3 to 50 times the area of ​​the first through hole 108. The area of ​​the second through hole 110 is 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 ventilation and heat dissipation. Designing the second through hole 110 to be larger than the first through hole 108 helps to expel debris that enters the protective cover 106 through the larger second through hole 110.

[0430] As shown in Figures 73 and 74, 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.

[0431] As shown in Figure 73, in one embodiment, the angle α2 between the second inclined surface 109 and the horizontal direction is 0° to 60°, and the angle α2 between the second inclined surface 109 and the horizontal direction is preferably 0°, 30°, and 60°. The larger the angle α2 between the second inclined surface 109 and the horizontal direction, the better the debris blocking effect, thereby minimizing the movement of debris toward the rear of the protective cover 106.

[0432] Please refer to Figures 73 and 74 simultaneously. In one embodiment, in order to discharge debris that has not been discharged from the second through-hole 110 and has moved to the rear of the protective cover 106, the rear 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 has not been 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.

[0433] As shown in Figures 73 and 74, 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 to 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 to the third through hole 114, so that the negative pressure effect generated at the third through hole 114 is better, and the debris is discharged from the inside of the protective cover 106 to the outside more cleanly.

[0434] In one embodiment, as shown in FIG75 , in order to simulate an air flow velocity of 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 velocity near the first through hole 108, the second through hole 110 and the third through hole 114, as shown in the figure, when the air flow velocity is 3.6 m / s, on the outside of the bottom of the protective cover 106, the air flow velocity near the first through hole 108 is 3.26 m / s, the air flow velocity near the second through hole is 5.15 m / s, and the air flow velocity near the third through hole 114 is 5.94 m / s. Obviously, when the air flow velocity is 3.6 m / s, the air flow velocity near the third through hole 114 is greater than the air flow velocity near the second through hole and the air flow velocity near the second through hole is greater than the air flow velocity near the second through hole. The flow velocity is greater than the air flow velocity near the first pass, and the Bernoulli effect is utilized (the Bernoulli effect means that in a fluid, if the velocity is small, the pressure is large; if the velocity is large, the pressure is small. The Bernoulli effect 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 smaller the pressure; the smaller the flow velocity of the fluid, the greater the pressure.). Therefore, at the second through hole 110 and the third through hole 114, the air flow velocity outside the protective cover 106 is greater than 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.

[0435] As shown in Figures 73 and 74, 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 are sequentially decreased. 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 are sequentially decreased. The flow rate of air flowing through the first through-hole 108, the second through-hole 110, and the third through-hole 114 increases sequentially. 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 within the protective cover 106.

[0436] As shown in Figures 73 and 74, in one embodiment, in the vertical direction, the height of the lowest end of the first through hole 108, the height of the lowest end of the second through hole 110, and the height of the lowest end of the third through hole 114 decrease in sequence. In cases where the debris is heavy and the effect of negative pressure on the debris discharge 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 the heavier 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 is higher than the height of the first through hole 108.

[0437] As shown in FIG74 , in one embodiment, the third through hole 114 is designed as a long strip structure.

[0438] As shown in Figure 74, 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, and the recess 112 formed by the recess consists 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.

[0439] In one embodiment, to enhance 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 scattering directly onto the power management device 219, potentially damaging it.

[0440] As shown in Figures 66 and 71 to 74, in one embodiment, a power supply fixing part 116 is provided on the frame 100, and the power supply device 200 includes a battery compartment 201 for installing a battery pack. The battery compartment 201 is fixed above the power supply fixing 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. 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. This is beneficial to the heat dissipation between the battery pack and the power management device 219, and they do not affect each other.

[0441] As shown in Figures 66 and 67 , in one embodiment, the power management mounting bracket 105 includes a connected fixing leg 1051 and a fixing plate 1052. The fixing leg 1051 is 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 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.

[0442] Referring to Figures 48 to 51, 66, and 68 to 69, 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. A power management device 219 is located below the battery compartment 201. In the front-to-back direction of the outdoor work equipment, the power management device 219 is located between the two side panels 216. This arrangement allows the power management device 219 to be directly connected upward to the electrical connection terminals 220 on the two side panels 216 through a wiring harness. Installing the power management device 219 between the two side panels 216, each of which is 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.

[0443] Referring to Figures 48 to 51 and Figure 66, in one embodiment, 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 219 more reasonable, and the battery pack can be electrically connected to the power management device 219 through the electrical connection terminals 220.

[0444] Please refer to Figures 48 to 51 at the same time. In one embodiment, an airflow generator 2031 (cooling fan) is provided below each electrical connection terminal 220, and the airflow generator 2031 is also directly connected to the power management device 219 downward through a wiring harness, which saves the use of wiring harnesses, saves raw material costs, and makes the layout of the entire outdoor work equipment more reasonable.

[0445] Please also refer to Figure 71. In one embodiment, the interface 217 on the front 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 at a height higher than the interface 217 on the front of the power management device 219. The height of the interface 217 on the front of the power management device 219 is higher than the lowest end of the front baffle 1054, and the cable 222 passes through the lowest end of the front baffle 1054 and is connected to the interface 217 on the front of the power management device 219. In this way, the lowest end of the cable 222 will be below the lowest end of the front baffle 1054. Since the 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 interface 217 on the front of the power management device 219, such an arrangement 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.

[0446] As shown in Figures 48 to 51 and 66 , the battery compartment 201 further 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 each of the two side panels 216 via wiring harnesses. This arrangement also reduces the wiring distance between the power management device 219 and the cooling fans.

[0447] As shown in Figures 44, 66, 71 and 74, 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 more in 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.

[0448] 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.

[0450] As shown in Figure 74, the bottom of the protective cover 106 is provided with two connected protrusions 113 protruding into the interior 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.
