The snow sweeping assembly 14 further comprises a snow sweeping bucket 144 and a propeller 145, and the first motor 142 is further used for driving the propeller 145 to work. The snow plough 144 is used for accommodating the snow plough 141, and the snow plough 141 rotates in the snow plough 144. The snow-removing bucket 144 includes two side walls 144a substantially perpendicular to the ground and parallel to each other, and the snow-removing paddle 141 is installed between the two side walls 144 a. The propeller 145 is installed inside the snow removal bucket 144, and snow on the rear side of the snow removal paddle 141 enters the snow removal bucket 144 from a snow inlet (not shown) of the snow removal bucket 144 under the action of the snow removal paddle 141, and is discharged from a snow outlet 142b to the snow thrower 15 after further action of the propeller 145.

The snow throwing device 15 comprises a snow throwing groove 151 mounted to the snow outlet 144b of the snow sweeping assembly 14 in rotational connection with the snow sweeping assembly 14.

Referring to fig. 3 and 4, operating device 16 includes a connecting rod 161 connected to housing 11, a power switch 162 (lock-off), a handle 163, a self-propelled trigger 164, a start trigger 165 (Auger), a self-propelled speed control assembly 166, a snow plow speed control assembly 167, and a snow chute adjustment assembly 168. The snow thrower adjustment assembly 168 and the diverter adjustment assembly 169 are used to adjust the position of the snow thrower 151 and the position of the diverter 152 of the snow thrower 15, respectively. Wherein, two handles 163 are respectively disposed at the left and right sides, and for the convenience of holding by the user, the handles 163 are inclined outward and downward with respect to the operating device 16. The self-propelled trigger 164 and the start trigger 165 are respectively connected to two handles 163, and for the sake of convenience of explanation, left and right directions are set according to the position where the user faces the operating device 16 to operate the snow blower 100, as shown in fig. 4. Specifically, in the present embodiment, the left trigger is the self-travel trigger 164, and the right trigger is the start trigger 165, but the absolute positions of the self-travel trigger 164 and the start trigger 165 are not limited. The self-propelled trigger 164 and the start trigger 165 both have a released state and a triggered state, with the triggering of the self-propelled trigger 164 controlling the actuation of the second motor 132 and the triggering of the start trigger 165 controlling the actuation of the first motor 142. The self-propelled trigger 164 is in the released state in fig. 3 and 4, and the start trigger 165 is in the triggered state. When the propel trigger 164 and the start trigger 165 are in the actuated state, they are at least partially engaged with the grip 163, and in fact, the user can hold the propel trigger 164 or the start trigger 165 in the actuated state with one hand while holding the grip 163. That is, the operation device 16 includes: a first trigger mechanism, such as a power switch 162, is operatively triggered; a second trigger mechanism, such as a start trigger 165, is operatively activated.

The snow sweeper 100 of the present embodiment has the following structural design of the self-propelled trigger 164 and the start trigger 165: the starting trigger 165 (Auger) is triggered independently and then released, and the starting trigger 165 is reset and rebounded; the self-propelled trigger 164 is released after being triggered alone, and the self-propelled trigger 164 is reset to rebound. Trigger from walking trigger 164 and start trigger 165 simultaneously, if only release from walking trigger 164, walk the resilience that resets of trigger 164, if only release start trigger 165, start trigger 165 does not reset and kick-backs, need release from walking trigger 164 and start trigger 165, start trigger 165 and just reset and kick-backs, walk trigger 164 and also reset simultaneously and kick-back.

The snowplow 100 also includes a circuit board (not shown) that is housed in the enclosure 11, and in this embodiment, the circuit board is located in a circuit board box (not shown) above the motor housing, and in the circuit board and circuit board box (not shown), without limitation, where the circuit board and circuit board box are located so as to facilitate installation, maintenance, routing, etc. The circuit board box has a waterproof function and is used for protecting the circuit board from being damaged due to the fact that the circuit board is wetted by rainwater. Within the circuit board box are mounted one or more circuit boards, such as: main control board, power management, self-propelled control board, lamp control board etc..

Because the starting of the motor has the hidden trouble of unconscious false starting compared with the starting of the traditional fuel engine, a snow sweeper with safe starting is needed.

The existing snow sweeper in the market at present mainly realizes double-starting operation for a mechanical mechanism limiting starting trigger, but the arrangement of the structure is limited by the size and the shape of the space such as a switch box, so that a user cannot operate a self-walking trigger with one hand and then trigger the starting trigger with the other hand.

To solve the above problems, the present invention provides a snow blower 100 having a dual start function, which is convenient for a user to perform a dual start operation with one hand.

Referring to fig. 5, as a partial circuit diagram of the snow sweeper 100 according to one embodiment, the snow sweeper 100 includes a control module 200, a power supply circuit 201, a driving circuit 202, a first motor 142, a first switch K1, and a second switch K2. It is to be understood that the circuit connection of the second motor 132 is similar to that of the present embodiment (refer to fig. 6).

The control module 200 is used to control the operation of the snowplow 100, and in this embodiment, specifically at least the operation of the first motor 142, in the embodiment shown in fig. 5. Optionally, the control module 200 includes any one or a combination of a single chip microcomputer or a Micro Control Unit (MCU), an ARM chip (high-performance Reduced Instruction Set Computing (RISC) microprocessor, an Advanced RISC Machine), and a DSP chip (general digital signal processor).

The power circuit 201 is electrically connected to the control module 200 for converting electrical energy from the energy device 12 into electrical energy for operation of the control module 200 and other circuit components. In the present embodiment, the energy source device 12 includes at least one battery pack 121, and the power circuit 201 may include a DC-DC conversion chip.

The driving circuit 202 is electrically connected to the winding 142a of the first motor 142 for driving the rotor of the first motor 142 to operate, and the driving circuit 202 includes a switching element. The driving circuit 202 shown in fig. 5 includes switching elements VT1, VT2, VT3, VT4, VT5, VT6, and the switching elements VT1 to VT6 can be field effect transistors, IGBT transistors, and the like. For the fet, the gate terminal of each switching element is electrically connected to the driving signal output terminal of the control module 200, and the drain or source of each switching element is electrically connected to the winding of the first motor 142. The switching elements VT 1-VT 6 change the on state according to the driving signal output by the control module 200, thereby changing the voltage state of the energy device 12 loaded on the winding of the first motor 142 and driving the first motor 142 to operate.

The first switch K1 is connected in conjunction with the first trigger mechanism to be triggered on by the first trigger mechanism, and when the first trigger mechanism is triggered, the first switch K1 is turned on.

The second switch K2 is connected in association with the second trigger mechanism to be turned on by being triggered by the second trigger mechanism, and the second switch K2 is turned on when the second trigger mechanism is triggered.

The first trigger mechanism is a power switch 162 and the second trigger mechanism can be either a start trigger 165 or a self-propelled trigger 164. In this embodiment, the second trigger mechanism is a start trigger 165. The first switch K1 is connected in association with the power switch 162, and when the power switch 162 is triggered, the first switch K1 is turned on; a second switch K2 is associated with the activation trigger 165, which second switch K2 is closed when the activation trigger 165 is triggered.

In the embodiment shown in fig. 6, the second trigger mechanism is a self-propelled trigger 164. A second switch K2 is connected to self-propelled trigger 164, and when self-propelled trigger 164 is triggered, second switch K2 is turned on.

The control module 200 is configured to: if the second switch K2 is turned on within a preset time when the first switch K1 is turned on, the first motor 142 is controlled to be started. As an implementation mode, the preset time range is 3-15 seconds, the preset time range is set to facilitate single-hand operation of a user, double starting actions are completed, and the setting of double starting can also prevent the user from unconsciously starting by mistake, so that safety accidents are avoided.

Likewise, the control module 300 shown in FIG. 6 may also be configured to: if the second switch K2 is turned on within a preset time when the first switch K1 is turned on, the second motor 132 is controlled to be started.

In this embodiment, as an embodiment, the first switch K1 is a signal switch, and the second switch is a signal switch. The first signal switch K1 and the second signal switch K2 are electrically connected to the control module 200, and the control module 200 can obtain the states of the first signal switch K1 and the second signal switch K2. In other embodiments, the snowplow 100 further comprises: a first switch state detection device (not shown) having an input end connected to the first switch K1 and an output end connected to the control module 200, the first switch state detection device being configured to detect an on/off state of the first switch K1 and send the on/off state to the control module 200; and a second switch state detection device (not shown) having an input end connected to the second switch K2 in a correlated manner and an output end connected to the control module 200, wherein the second switch state detection device is used for detecting the on-off state of the second switch K2 and sending the on-off state to the control module 200, and the control module 200 controls the first motor 142 of the snow sweeper 100 according to the received on-off states of the first switch K1 and the second switch K2.

In this manner, to start the snow blower 100, the first motor 142 or the second motor 132 can be started by first triggering the power switch 162 (lock-off), and then triggering the start trigger 165 or the self-propelled trigger 164 within a predetermined time (the predetermined time is generally 3 to 15 seconds) within the predetermined time for triggering the power switch 162. Through the relevance of the double-starting action time, the false starting can be prevented, and meanwhile, the double-starting operation can be conveniently completed by one hand. The time setting is convenient for a user to finish double-action operation with one hand and double hands, and the applicability is wide.

Optionally, when the second trigger mechanism is released, the second switch K2 is open; the control module 200 is configured to: when the second switch K2 is turned off, the first motor 142 or the second motor 132 is controlled to stop driving.

In the embodiment shown in fig. 5, when the start trigger 165 is released, the second switch K2 opens; the control module 200 is configured to control the first motor 142 to stop driving when the second switch K2 is turned off.

In the embodiment shown in fig. 6, when self-propelled trigger 164 is released, second switch K2 is open; the control module 300 is configured to control the second motor 132 to stop driving when the second switch K2 is turned off.

When the snow blower 100 is turned off, the start trigger 165 and the self-propelled trigger 164 are simply released. Compared with the traditional double-starting action design realized through the limiting mechanism, the structural component of the snow sweeper in the embodiment has the advantages that the requirement on the mechanical structure is greatly reduced, the arrangement and the appearance design of developers and performance structures are facilitated, and the cost can be reduced.

It will be appreciated that the above described embodiment is merely a double action activation of the first motor 142 to activate the snow sweeping assembly 14 for snow sweeping. Similarly, the second motor 132 may be driven to travel by safely and conveniently starting the second motor 132 by the above-described double start operation. At this time, the second triggering mechanism is a self-propelled trigger 164 for dual-action activation of the second motor 132, and the dual-action activation of the second motor 132 is similar to the dual-activation of the above-mentioned motors, and will not be described herein again.

Optionally, the snow blower 100 further comprises an indicator light connected to the control module 200, the indicator light having at least a first state and a second state, the first state being used for indicating that only the first switch K1 is turned on, the second state being used for indicating that the first switch K1 is turned on and the second switch K2 is turned on within a preset time when the first switch K1 is turned on. In some specific embodiments, when the first switch K1 is turned on, the indicator light flickers, and when the second switch K2 is turned on within a preset time of turning on the first switch K1, the indicator light is normally turned on, although the indicator light may be set to other two different lighting modes. With this arrangement, when the indicator light blinks, the user can be reminded to press the second trigger mechanism (the self-propelled trigger 164 or the start trigger 165) within a preset time. When the indicator light is constantly on, it indicates that the snow plow assembly 14 of the snowplow 100 is operating properly.

As a specific embodiment, the indicator lamp includes a battery indicator lamp 173, which can be used to display the status of the battery pack 121, and has two states of flashing and normally on, and has two colors of red and green. The display logic of the battery indicator 173 is as follows: 1. the battery pack 121 is inserted, the motor or the illuminating lamp is not started, and the battery indicator lamp 173 is in an off state; 2. starting the battery pack 121 to supply power or directly starting working pieces such as a motor, an illuminating lamp and the like, wherein the state of the battery indicator 173 is shown according to the state of the energy source device 12 according to a preset state; 3. when the power switch 162 is triggered, no matter what state the battery indicator 173 is, the battery indicator 173 will flash for a preset time (e.g., 3 seconds to 15 seconds), and after the preset time, if the start trigger 165 or the self-propelled trigger 164 is triggered, the green light is normally on to indicate the current state of the snow sweeper 100, and if the start trigger 165 is not triggered, the battery indicator 173 will return to the state before the preset time. Thus, a green light flashing on the battery indicator 173 indicates that the power switch 162 has been activated, alerting the user that the current status may trigger the trigger 165 to turn on the motor to drive the snow plow 141. Of course, the battery indicator 173 may include a plurality of battery indicator 173, the plurality of battery indicator 173 may be different colors, such as green, red, and orange, and each battery indicator 173 may have different lighting states, such as normally on, flashing, and the like. Different lighting states or combinations of different lighting states of one or more battery indicator lights 173 may be used to display various different states of the snowplow 100 to alert and indicate to a user, for example, normal operating conditions, under-voltage protection conditions, over-temperature conditions, and over-load protection conditions. For example, when the power device has two battery packs 121, each battery pack has its own indicator light, and when one battery pack 121 has its green light on and the other battery pack has its red light on, the battery indicator light 173 is turned on to indicate that the power device 12 can provide power to the snowplow 100.

Referring to fig. 5, as an embodiment, the snow-sweeping paddle speed adjustment assembly 167 includes a snow-sweeping speed adjustment switch 204 and a slide rheostat R1, an output terminal of the slide rheostat R1 is electrically connected to the control module 200, and a slide of the slide rheostat R1 is connected to the snow-sweeping speed adjustment switch 204. When the snow sweeping speed regulating switch 204 is moved to different positions, the resistance value of the corresponding ground sliding resistor R1 connected to the circuit is changed, and the changed resistance value can be converted into a voltage signal through a related circuit, so that the control module 200 can obtain the rotating speed of the motor expected by an operator according to the voltage signal of the sliding resistor R1 related to the snow sweeping speed regulating switch 204 and a pre-stored voltage-rotating speed table or voltage-rotating speed formula, and the control module 200 outputs a ground control signal to control the motor to output the rotating speed expected by the operator.

As an embodiment, the rotation speed of the first motor 142 driving the snow paddle 141 has five gear positions, and the first motor 142 has a constant rotation speed in each gear position, for example, respectively: 1100 rpm, 1000 rpm, 900 rpm, 800rpm, 700 rpm. The method by which the control module 200 controls the first motor 142 is as follows: the control module 200 acquires the voltage signal of the sliding rheostat R1 to judge the intention of the operator, and the control module 200 matches and matches a pre-stored voltage-rotating speed table according to the voltage signal of the snow sweeping speed regulating switch 204 to acquire the rotating speed of the first motor 142 corresponding to the voltage signal, wherein as an implementation mode, the voltage signal corresponds to the rotating speed of the first motor 142 as shown in the following table 2, and through the arrangement, the snow sweeper 100 is more convenient to operate and control.

When the self-propelled speed regulation switch 205 is moved to different positions, the resistance value of the corresponding sliding resistor R2 connected to the circuit changes, and the changed resistance value can be converted into a voltage signal through a related circuit, so that the control module 200 can obtain the rotating speed of the second motor 132 expected by the operator according to the voltage signal of the sliding resistor R2 related to the self-propelled speed regulation switch 205 and a pre-stored voltage-rotating speed table or voltage-rotating speed formula, and the control module 300 can control the second motor 132 to output the rotating speed expected by the operator according to the output control signal of the control module 300 so as to drive the road wheels 143 of the snowplow 100 to walk.

In one embodiment, the snow sweeper 100 is configured to adjust the speed of the second motor 132 in a stepless manner. In this embodiment, the self-walking is divided into forward, reverse and neutral. The method by which the control module 200 controls the second motor 132 is as follows: the control module 300 acquires the voltage signal of the slide rheostat R2, determines the intention of the operator, and the control module 300 matches a pre-stored voltage-tachometer with the voltage signal of the slide rheostat R2 associated with the self-propelled speed-regulating switch 205 to acquire the rotation speed and the state of the second motor 132121 corresponding to the voltage signal. For example, 0-2500 mv corresponds to 0-1.2 m/s of the self-propelled forward gear in equal proportion; 2501-4000 mv is neutral (speed is zero); 4001-5000 mv corresponds to 0-0.2 m/s of self-propelled reverse gear in equal proportion.

As an embodiment, the operation method of the snow sweeper 100 comprises the following steps:

selecting a desired gear, pressing the self-propelled trigger 164, and advancing or retreating the snow sweeper 100 or keeping the snow sweeper in a neutral position;

when the self-propelled trigger 164 is pressed, the self-propelled trigger 164 is released, and the snow sweeper 100 stops running;

when the self-propelled trigger 164 is pressed down, if the state of the snow sweeper 100 going forward or backward needs to be changed, the self-propelled speed regulating switch 205 needs to be adjusted to a corresponding gear, the snow sweeper 100 stops walking, then the self-propelled trigger 164 is released, and the self-propelled trigger 164 can be pressed down again after the speed of the corresponding gear is adjusted. For example, when the snow sweeper 100 is moving forward, if the snow sweeper is to be moved backward, the speed control switch 205 needs to be adjusted to a backward position, at which point the snow sweeper 100 stops traveling, and then the self-propelled trigger 164 needs to be released, and the snow sweeper 100 will move backward until the backward speed is adjusted or the self-propelled trigger 164 is pressed again.

In some embodiments, the snowplow 100 further includes an illumination device 206 for providing illumination to the snowplow 100 during low light conditions. In the present embodiment, the lighting device 206 includes a lighting assembly 170 mounted to a position above the snow hopper 144, and two forward illuminating lamps 171 provided on the operation panel of the operation device 16, the illuminating lamps 171 being located on the left and right sides of the front of the operation panel, respectively. Of course, the lighting device 206 may be mounted in other reasonable positions.

The snowplow 100 is further provided with a light switch 172, the light switch 173 controls the light assembly 170 and the light 171, and the method for controlling the lighting device 206 by the light switch 172 is as follows: the first time the lighting switch 172, the lighting assembly 170 and the lighting lamp 171 are fully powered; the second time of triggering the lighting switch 172 to turn off the two lighting lamps 171 on the operation panel; the third time the light switch 172 is activated, turning off the light assembly 170 on the snow plow 144. In addition, the control module 200 controls the lighting assemblies 170 and 171 to be automatically turned off after a preset time, which is set by a user's selection, for example, 5 minutes, when the snowplow 100 is not in operation.

Further, the self-traveling speed v of the snow sweeper 100 is set to v, the rotation speed of the snow-sweeping paddle 141 is set to n, and the user can adjust the self-traveling speed v of the snow sweeper 100, the rotation speed of the main motor, the rotation speed n of the snow-sweeping paddle 141, or the rotation speed of the second motor 132 by operating the self-traveling speed control switch 205 and the snow-sweeping speed control switch 204, respectively. To ensure high snow removal efficiency, it is appropriate that the self-traveling speed v of the snow sweeper 100 and the rotation speed n of the snow paddle 141 are substantially positively correlated, and in addition, snow removal efficiency can be made high when v and n satisfy the functional relationship x = f (v, n).

The snow removing amount is set to be Q, the power consumption required by the snow sweeper 100 to complete the work amount with the snow removing amount being Q is set to be N, and when the snow removing amount Q/N of unit power consumption reaches a certain range value, the snow sweeper 100 has better snow removing performance.
