Description

Technical Field

[0001] The present invention relates to the technical field of lawn mower starting devices, and particularly to an electric starting mechanism for a lawn mower and garden equipment. Background Art

[0002] Among many garden equipments, how to start a lawn mower is crucial. Some existing means adopt an electric starting method to drive the lawn mower to start. Most of the electric starting methods use a battery pack to provide electric energy to a starting motor, so that the starting motor drives the lawn mower to start.

[0003] In the field of garden equipment, lead-acid batteries and special batteries have been widely used for a long time. However, these power sources are usually designed to be matched with specific equipment and cannot be used interchangeably across different equipments. This limitation not only increases the user's usage cost, but also restricts the flexibility and interchangeability of the equipments.

[0004] In recent years, with the progress of lithium-ion battery technology, more and more garden tools have started to use lithium battery packs. Lithium batteries have the advantages of high energy density, light weight, long cycle life, etc., and have gradually become the mainstream power source for electric garden tools. However, existing battery packs are usually designed for a working mode of discharging with medium and small currents for a long time, such as the usage scenarios of tools like electric lawn mowers and electric saws.

[0005] However, when these battery packs are tried to be used for the electric starting motor of an engine, due to the significant differences in working characteristics, serious problems may be faced. The electric starting motor of an engine requires large current discharge in a short time, which is completely different from the long-time medium and small current discharge mode of the battery pack in garden tools. Without protection, such large current discharge may cause irreversible damage to the battery pack, such as battery overheating, capacity attenuation, and even safety hazards, thus seriously affecting the life and reliability of the battery pack.

[0006] Therefore, there is an urgent need for a solution that enables the battery pack to be used safely and reliably in different working modes, especially in the scenario of large current discharge in a short time for the electric starting motor of an engine. The purpose of the present invention is to introduce a protection mechanism to ensure that the battery pack will not be damaged when used for the electric starting motor of an engine, thereby extending the service life of the battery pack and improving its versatility. Summary of the Invention

When the transition gear rotates, the movable gear rises along the spiral guide rail and meshes with the crankshaft mechanism. After the lawn mower is started, the movable gear disengages from the meshing and returns along the spiral guide rail.

[0012] The present invention also includes the following technical solutions: The brake includes a fixed plate, a movable plate, and a tension spring.

Detailed implementation manners

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0022] In the description of the present application, unless otherwise clearly specified and limited, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; unless otherwise specified or stated, the term "plurality" means two or more; the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. And in the present invention, only a partial illustration of the lawn mower 2 (the structural illustration of the engine) is given in the explanatory drawings, which is the main inventive point of the present invention. The frame and some components of the lawn mower 2 are omitted, and the omitted parts are the commonly used mechanisms of the lawn mower 2 in the prior art. In addition, as Figure 1 shown, it is defined that the X direction is the front-back direction of the lawn mower, the Y direction is the left-right direction, and the Z direction is the up-down direction. Such a definition is only for convenience of understanding and does not have a special meaning.

[0023] A specific embodiment of an electric starting mechanism for a lawn mower: As Figures 1 - 2 shown, the present invention provides an electric starting mechanism 1 for a lawn mower 2. In the present application, the electric starting mechanism 1, the one-way driving mechanism 3, the ignition member 4, the fan blade 5, and the manual starting mechanism 6 are all installed on the lawn mower 2. The present application has the advantages of high voltage stability, perfect braking function, reasonable structural layout, etc., and is suitable for the electric starting requirements of various lawn mowers 2.

[0024] Specifically, as Figures 1 - 2 shown, the lawn mower 2 further includes a crankshaft mechanism 21. The lawn mower 2 is a key component that converts the chemical energy of fuel into mechanical energy. And the crankshaft mechanism 21 in the present application is used to convert mechanical energy into chemical energy for starting the lawn mower 2. Simply understood, it is to start the lawn mower 2 by driving the crankshaft mechanism 21 to rotate. In the present application, the lawn mower 2 is also provided with a housing, which can protect the internal components from external physical impacts or collisions and extend the service life of the equipment. And the housing is made of insulating material, which can prevent the internal electrical components from directly contacting the external environment and avoid potential safety hazards such as electric leakage or short circuit. The housing can also prevent the operator from accidentally contacting the internal rotating components (such as the crankshaft mechanism 21) and reduce the occurrence of safety accidents.

[0025] As Figures 1 - 2 shown, in the present application, the electric starting mechanism 1 includes a mounting plate 11, a battery compartment 12, a battery pack 13, a controller 14, a starting motor 15, and a brake 16. Among them, as Figure 8 and Figure 9 shown, the mounting plate 11 is detachably mounted on the back of the lawn mower 2 ( Figure 1 the negative direction of the X direction in the figure), which is convenient for installation and disassembly. In this embodiment, the fastener is preferably a bolt. In other embodiments, the fastener can also be a screw, washer, rivet, pin, snap ring, key, anchor bolt, etc. The battery compartment 12 is snap-fitted on the mounting plate 11, and the battery pack 13 is installed in the battery compartment 12 by plugging, realizing the quick installation and replacement of the battery pack 13.

[0026] In the present application, the battery compartment 12 can also be installed on the side, top or bottom of the lawn mower 2 through the mounting plate 11, rather than being limited to the back, which can bring various beneficial effects. For example, it can disperse the weight distribution of the lawn mower 2, avoid the center of gravity being too concentrated, and improve the stability of the overall structure. Select according to the actual installation situation, and there is no excessive limitation on this. Among them, the size of the opening of the battery compartment 12 is adapted to the size of the battery pack 13, which is convenient for the replacement of the battery pack 13. The battery pack 13 is one of a lithium-ion battery, nickel-cadmium battery, nickel-metal hydride battery and lead-acid battery, improving the versatility and resource utilization rate of the battery pack 13.

[0027] The controller 14 is electrically connected to the battery pack 13 through the battery compartment 12 to ensure that the electric energy of the battery pack 13 can be transmitted to the controller 14. In this embodiment, the controller 14 is mounted on the mounting plate 11 by bolts, and the layout is compact and reasonable, which is convenient for improving the space utilization rate. The starting motor 15 and the brake 16 are both installed on the side of the lawn mower 2. The starting motor 15 is electrically connected to the controller 14 and is used to drive the crankshaft mechanism 21 of the lawn mower 2 to rotate. The starting switch 17 is arranged on the brake 16 and is turned on and off under the drive of the brake 16. The starting switch 17 is electrically connected to the controller 14.

[0028] In the present application, as Figures 8 - 9 and Figure 11As shown in the figure, the controller 14 includes an input circuit electrically connected to the battery compartment 12, a starting circuit electrically connected to the starting switch 17, and a driving circuit electrically connected to the starting motor 15. The driving circuit is respectively connected in series with the starting button on the armrest and the starting switch 17 on the brake 16. When the operator closes the pull rod, the starting switch 17 on the brake 16 is turned on. When the starting button on the armrest is pressed again, the driving circuit is turned on, and the controller 14 immediately prepares to turn on the starting circuit. The starting button is convenient for the user to operate. The controller 14 detects the voltage and status of the battery pack 13 before each connection; if the voltage of the battery pack 13 is lower than the set value or the status is abnormal, the controller 14 alarms through the flashing of the indicator light and controls the brake 16 to drive the closing of the starting switch 17 to disconnect the starting circuit. By detecting the status of the battery pack 13 in real time by the controller 14 and automatically disconnecting the starting circuit when abnormal, the battery pack 13 is prevented from being damaged. If the voltage of the battery pack 13 is higher than the set value and the status is normal, the starting circuit is turned on, and the starting motor 15 rotates to start the lawn mower 2.

[0029] In the present application, when the controller 14 is abnormal (such as too high, too low voltage or malfunction), the indicator light will timely remind the operator to avoid equipment damage or safety accidents caused by ignoring the problem. The safety and reliability of the system are enhanced, and the accident risk is reduced.

[0030] In the present application, the controller 14 further includes a control module and a timing module. The control module is connected to the starting button and is used to detect the pressing state of the starting button; the timing module is used to set the maximum continuous on time of the starting button; wherein, the control module starts the timing module after the starting button is pressed and automatically disconnects the starting circuit after reaching the maximum continuous on time. In this embodiment, the control module can detect the state of the starting button and control the starting circuit through programming. The timing module is implemented by a hardware timer or a software timer to set the maximum continuous on time (such as 1.5 seconds). The starting button is connected in series with the starting switch 17 of the circuit in the starting circuit. After the user presses the button, the circuit is turned on, and the starting motor 15 starts to work. The controller 14 monitors the state of the starting button and the time of the timing module in real time to ensure that the circuit is automatically disconnected after reaching the maximum continuous on time. If the voltage of the battery pack 13 is lower than the set value or the system status is abnormal, the controller 14 alarms through the flashing of the indicator light and automatically disconnects the starting circuit.

[0031] Such as Figure 2 and Figure 3As shown, in this application, a one-way drive mechanism 3 is assembled on the main shaft of the starting motor 15 for driving the crankshaft mechanism 21 to rotate. The one-way drive mechanism 3 includes a transition gear 31, a spiral guide rail 32, a movable gear 33, and an anti-disengagement block 34. The transition gear 31 is used to connect with the main shaft of the starting motor 15 to facilitate the starting motor 15 to drive the transition gear 31 to rotate. The spiral guide rail 32 is installed on the transition gear 31 and can rotate with the rotation of the transition gear 31. The movable gear 33 is assembled on the spiral guide rail 32. When the spiral guide rail 32 rotates with the transition gear 31, the movable gear 33 moves upward along the spiral guide rail 32 until the movable gear 33 meshes with the crankshaft mechanism 21, thereby driving the crankshaft mechanism 21 to rotate and driving the lawn mower 2 to start. The process of the movable gear 33 moving up and down along the spiral guide rail 32 can play a role in buffering and adjustment. The anti-disengagement block 34 is installed at the top of the spiral guide rail 32 to prevent the movable gear 33 from disengaging from the spiral guide rail 32 when moving upward along the spiral guide rail 32. After the lawn mower 2 starts, the movable gear 33 disengages from the crankshaft mechanism 21 and moves downward along the spiral guide rail 32, ensuring the stability of the lawn mower 2.

[0032] As Figure 4 and Figure 5 shown, in this application, the brake 16 includes a fixed plate 161, a movable plate 162, and a tension spring 163. Among them, the fixed plate 161 is fixedly installed on the lawn mower 2, the movable plate 162 is rotatably installed on the fixed plate 161 and is connected to the fixed plate 161 through the tension spring 163. The start switch 17 is installed on one side of the fixed plate 161 close to the starting motor 15. The movable plate 162 rotates around the fixed plate 161 to control the opening and closing of the start switch 17. In this application, through the coordinated work of the fixed plate 161, the movable plate 162, and the tension spring 163, the design of the brake 16 realizes the mechanical control of the start switch 17, thereby indirectly controlling the operating state of the starting motor 15 to ensure that the lawn mower 2 starts or stops in a timely manner.

[0033] Among them, as Figure 5 and Figure 10 shown, on the side of the movable plate 162 close to the lawn mower 2, there is a brake piece 1621 bent upward, and on the side far from the lawn mower 2, there are a protrusion 1622 and a connection hole 1623. A cable is externally connected to the connection hole 1623. The cable is used to control the rotation of the movable plate 162 so that the brake piece 1621 approaches or moves away from the lawn mower 2, and the protrusion 1622 is used to control the opening and closing of the start switch 17. By controlling the rotation of the movable plate 162 through the cable, the actions of the brake piece 1621 (approaching or moving away from the lawn mower 2) and the closing / opening of the start switch 17 can be achieved simultaneously. This linkage design simplifies the operation process and improves the integration of the system.

[0034] As Figure 5 and Figure 10As shown, a friction plate 1624 is also provided on the brake pad 1621, so that when the brake pad 1621 is close to the lawn mower 2, it can brake the rotation of the crankshaft mechanism 21 on the lawn mower 2 faster, improving the braking effect. Among them, an ignition component 4 is also provided on the fixing plate 161 to provide the required voltage for the spark plug on the lawn mower 2, which belongs to a relatively conventional ignition method in the lawn mower 2.

[0035] As Figures 2 - 6 shown, several fan blades 5 arranged at circumferential intervals around the crankshaft mechanism 21 are also assembled on the top of the crankshaft mechanism 21 of the lawn mower 2. The fan blades 5 will generate an air flow when the crankshaft mechanism 21 rotates, accelerating the flow of the air around the lawn mower 2, thereby effectively reducing the temperature of the lawn mower 2 and preventing overheating.

[0036] As Figure 2 、 Figure 4 and Figure 7 shown, in this application, a manual starting mechanism 6 is also provided on the crankshaft mechanism 21 of the lawn mower 2. Among them, the manual starting mechanism 6 includes a reel and a pull rope wound around the reel for driving the reel to rotate. The reel is sleeved on the crankshaft mechanism 21 for driving the crankshaft mechanism 21 to rotate. The manual starting mechanism 6, as a mechanical starting method, is not affected by electronic component failures or power supply problems. Compared with the electric starting system, it does not have complex circuits and electronic components, so it will not have situations where it cannot be started due to circuit failures, insufficient battery power, etc. This is very important in emergency situations or in occasions where high reliability of the equipment is required.

[0037] Specifically, the operator holds the other end of the pull rope and pulls the pull rope forcefully and quickly. When the pull rope is pulled, the reel starts to rotate. According to the principle of interaction of forces, the pull rope exerts a pulling force on the reel, causing the reel to generate a rotational motion. As the reel rotates, other components of the manual starting mechanism 6 connected to it also start to work together. The rotation of the reel will transmit the power to the crankshaft mechanism 21 through a series of gear transmissions or belt transmissions. After the crankshaft mechanism 21 receives sufficient torque, it starts to rotate, thereby driving the entire lawn mower 2 into the starting state. During this process, the operator needs to continuously pull the pull rope to keep the reel rotating until the lawn mower 2 is successfully started.

[0038] A specific embodiment of a garden device: A garden device uses the electric starting mechanism 1 for the lawn mower 2 in the above embodiment. The electric starting mechanism 1 is located on the lawn mower 2, and the lawn mower 2 is installed on the garden device. The garden device is one of a zero-turn radius lawn mower, a walk-behind lawn mower, a riding lawn mower, a leaf blower, a snow blower, a high-pressure washer, a portable generator, a micro-tiller, and a log splitter. In this application, this lawn mower 2 can be installed on various garden devices such as a zero-turn radius lawn mower, a walk-behind lawn mower, and a riding lawn mower, and has strong adaptability. Different types of garden devices have different power requirements and working environments, but the electric starting mechanism 1 can well meet their starting requirements. For example, when the snow blower works in a cold environment, the electric starting mechanism 1 can reliably start the lawn mower 2 to ensure the normal operation of the snow blower.

[0039] At the same time, its structure is relatively simple and the maintenance cost is low. Whether it is in the production and manufacturing link or the maintenance during use, installation, disassembly, and repair can be conveniently carried out. For example, in a portable generator, the electric starting mechanism 1 can be maintained as an independent module and can be quickly replaced when a fault occurs, reducing the downtime of the device.

[0040] According to the above description of this specification, those skilled in the art can also understand the following terms used, such as the terms indicating orientation or position relationship, such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or position relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in the specific orientation. Therefore, the above orientation or position relationship terms cannot be understood or interpreted as a limitation to the solution of the present invention.

[0041] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically and clearly defined.
