DETAILED DESCRIPTION

[0066] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0067] In the description of the present application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0068] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0069] Embodiment 1:

[0070] The present embodiment provides a pushable working machine, which includes a handle, a wheel assembly and at least one drive motor. The handle forms a grip for a user to hold, and the user can operate the pushable working machine by holding the handle. The wheel assembly includes at least one wheel, and the number of wheels can be set to 1, 2, 3, 4 or more according to needs. At least part of the drive motor is arranged in the wheel, so as to at least drive the wheel to move. Specifically, the motor shaft of the drive motor coincides with the rotation axis of the corresponding wheel, and the motor shaft of the drive motor is directly connected to the wheel, so as to directly drive the corresponding wheel to rotate. More specifically, the number of drive motors and the number of wheels can be the same, so as to realize that only one wheel is driven to rotate by one drive motor; of course, the number of drive motors and the number of wheels can also be different, so as to realize that two wheels with substantially coincident rotation axes are driven by one drive motor. In some specific embodiments, the drive motor is a brushless motor. In some more specific embodiments, the drive motor is an outer rotor hub motor.

[0071] In this embodiment, the total rated power P1 of the drive motor is less than or equal to 1000W. Optionally, the total rated power P1 of the drive motor is greater than or equal to 100W and less than or equal to 1000W. It should be noted here that the total rated power of the drive motor is the sum of the powers of all the drive motors used to drive the wheel assembly to move. If there are multiple drive motors (for example, the drive motor includes a hub motor and a non-hub motor) that drive different wheels of the wheel assembly respectively, the total rated power of the drive motor is the sum of the powers of the hub motor and the non-hub motor. It should be particularly noted that the total rated power of the drive motor is not the output power of the pushable working machine. For example, when the pushable working machine is specifically a hand-propelled four-wheel drive working machine, the total rated power P1 of its drive motor is as high as 1000W. The rated voltage U1 of the drive motor is greater than or equal to 12V and less than or equal to 120V. Optionally, the rated voltage U1 of the drive motor is greater than or equal to 20V and less than or equal to 120V. The rated voltage U2 of the pushable working machine is greater than or equal to 18V, optionally, the rated voltage U2 of the pushable working machine is greater than or equal to 36V, and further optionally, the rated voltage U2 of the pushable working machine is greater than or equal to 40V and less than or equal to 120V. The efficiency η1 of the drive motor is greater than 70%. In a specific embodiment, the efficiency η1 of the drive motor is 75%; in another specific embodiment, the efficiency η1 of the drive motor is 80%; in another specific embodiment, the efficiency η1 of the drive motor is 85%.

[0072] The pushable working machine directly connects the driving motor to the wheel by placing at least part of the driving motor inside the wheel, thereby omitting the transmission mechanism. The pushable working machine has the advantages of simple structure, easy control, small space occupation and low requirements on assembly process.

[0073] It should be noted that the pushable working machine may be cooled by natural cooling or by injecting oil between the wheel hub motor and the wheel for cooling.

[0074] The pushable working machine may specifically be a snowplow and a lawn mower, which are respectively described in detail below by taking the snowplow and the lawn mower as examples.

[0075] Figure 1 A schematic diagram of a snowplow 1000 as a specific embodiment is shown. The snowplow 1000 includes a main body 100 and an operating assembly 110 connected to the main body 100. The operating assembly 110 includes an upper connecting rod, and the main body 100 includes a lower connecting rod.

The energy system in this embodiment includes a dual battery pack and is a DC lithium battery.

[0078] See also Figures 1 to 3 As shown, the wheel assembly 130 includes two first rear wheels 131 that can travel on the ground. The first rear wheels 131 rotate relative to the main machine 100 around the rotation axis 101, so that the snowplow 1000 moves relative to the ground. Specifically, the two first rear wheels 131 are symmetrically distributed on both sides of the main machine 100 and are connected by a running wheel axle. In this embodiment, the first rear wheel 131 includes a tire 1311 and a hub motor 1312 disposed in the tire 1311. The hub motor 1312 is used to drive the tire 1311 to rotate relative to the main machine 100 around the rotation axis 101, so that the snowplow 1000 moves relative to the ground.

[0079] The snow removal system 140 includes a snow removal paddle and a snow throwing paddle.

Wherein, the first straight line is perpendicular to the second straight line. The first accommodation space and the second accommodation space are interconnected. The first accommodation space is defined with a snow inlet, and the second accommodation space is defined with a snow outlet. Under the action of the snow removal paddle, snow enters the snow removal paddle housing from the snow inlet of the snow removal paddle housing, and is discharged from the snow outlet after further action of the snow throwing paddle. The main body housing 160 also includes a snow outlet tube protruding from the second accommodation space, and the snow outlet tube is basically connected to the snow outlet along the tangential extension of the cylinder. The snow removal system 140 also includes a power motor for driving the snow removal paddle to rotate about the first straight line as the axis and driving the snow throwing paddle to rotate about the second straight line as the axis.

[0080] The snow throwing system 150 of the snowplow includes a guide plate and a snow throwing member. The snow throwing member is surrounded by a semi-enclosed channel and defined with an opening. The first end of the snow throwing member is rotatably connected to the snow throwing paddle housing to connect the second accommodating space and the outside world. In other words, the snow throwing member is connected to the snow throwing paddle housing and the guide plate to form a continuous channel for snow removal. The guide plate is installed to the second end of the snow throwing member. In this embodiment, the guide plate is installed to the top of the snow throwing member. Snow is thrown into the air after passing through the snow throwing paddle housing, the snow discharge tube, the snow throwing member and the guide plate. The snow throwing system 150 also includes a first drive device and a second drive device. The first drive device is connected to the upper part or the middle part of the snow throwing member, and is used to drive the snow throwing member to rotate around the first axis relative to the main unit 100. The second drive device is connected to the guide plate, and is used to drive the guide plate to rotate around the second axis relative to the snow throwing member. The first axis is perpendicular to the second axis. Optionally, the first drive device and the second drive device can be a combination of a motor and a gear.
