Description

Technical Field

[0001] The present application relates to the field of lawn mower equipment, and in particular to a pure electric new energy reel-type lawn mower. Background Art

[0002] Existing lawn reel mowing equipment mainly uses fuel as its power source, which has the disadvantages of high emission pollution, high noise, complex maintenance, complex operation, inaccurate precision, and high operating costs. In addition, due to the heavy weight of fuel equipment, the indentation caused to the lawn has a greater impact, which is not suitable for some scenes with high requirements for lawn quality. Existing electric lawn mowing equipment has certain limitations in battery technology and battery life, and cannot meet the needs of long-term, high-intensity work.

[0003] In the related art, most existing electric lawn mowing equipment uses lead-acid batteries or early lithium batteries, which limits the overall endurance and power output of the lawn mower, making it difficult to use continuously on large lawns.

[0004] Therefore, there is an urgent need for a zero-emission lawn mower that meets modern environmental protection requirements and can meet long-term lawn maintenance needs. Summary of the invention

[0005] The present application provides a pure electric new energy reel-type lawn mower, the purpose of which is to provide a lawn mower that has zero emissions, meets modern environmental protection requirements and can meet long-term lawn maintenance needs.

[0006] The present application provides a pure electric new energy reel-type lawn mower, which adopts the following technical solution:

[0007] A pure electric new energy reel-type lawn mower, comprising a frame, a drive system, a lithium battery power system, a control panel and a lawn mowing system, wherein the frame adopts a modular design; the drive system is used to drive the frame to operate and the lawn mowing system to cut grass; the lithium battery power system is used to improve the equipment life and provide stable power output; the control panel is used for the operator to control the lawn mower's mowing speed and the lawn mower's blade speed; the lawn mowing system is used to mow the corresponding lawn; the lithium battery power system is composed of a lithium battery pack.

[0008] By adopting the above technical solutions, the frame is modularly designed, which is convenient for the maintenance of the equipment and the replacement of parts. The lithium battery power system consists of a lithium battery pack with a relatively high capacity. In combination with a high-efficiency motor, it can effectively increase the endurance time of the equipment and provide stable power output. In this setting method, the lawn mower is driven purely by electricity during the lawn mowing process through the lithium battery power system, changing the original hydraulic drive mode of the lawn mower, and thus can effectively avoid the pollution of the lawn caused by oil leakage during the operation of the lawn mower. The advanced lithium battery pack improves the endurance time of the lawn mower equipment and can meet the long-term lawn maintenance needs. Compared with the original gasoline engine, during the operation of the lawn mower with pure electric drive, there is no need for manual adjustment of the choke and throttle valve, and it can move forward and backward with a single pedal, greatly reducing the operation difficulty of the lawn mower. By adopting the new energy technology of the lithium battery power system, zero emission of polluted gas can be achieved for the lawn mower, and zero emission is realized during the operation of the equipment, thus meeting the modern environmental protection requirements. At the same time, the noise of the electric drive is significantly reduced compared with the fuel drive, making it suitable for use in residential areas and places with high requirements for quiet environment. The new energy equipment with a lithium battery power system abandons the traditional internal combustion engine and liquid mechanical transmission system, avoiding problems such as leakage of coolant, lubricating oil or hydraulic oil, which is beneficial to protecting the lawn from pollution. Moreover, there is no need to replace consumable parts such as engine oil, spark plugs, and air filters, and the daily maintenance cost is significantly reduced.

[0009] Preferably, the mowing system includes a front right cutter, a front left cutter, and a rear cutter. The front right cutter and the front left cutter are distributed on the left and right sides of the front end of the frame, and the rear cutter is distributed at a position close to the rear end of the frame. The front right cutter, the front left cutter, and the rear cutter are integrally distributed on the frame in a "pin" shape structure, and the drive system controls the front right cutter, the front left cutter, and the rear cutter to mow the lawn.

[0010] By adopting the above technical solutions, when specifically mowing the lawn, the front right cutter, the front left cutter, and the rear cutter can simultaneously mow different positions of the lawn, which is beneficial to improving the efficiency of the lawn mower in mowing the lawn. At the same time, by using three groups of blades, namely the front right cutter, the front left cutter, and the rear cutter, to mow the lawn, the lawn mower can support multiple mowing modes, thus providing more flexible operation options for lawn mowing.

[0011] Preferably, the drive system includes a drive motor and cutter motors. The drive motor is used to drive the overall operation of the frame, and the cutter motors are used to drive the corresponding front right cutter, front left cutter, and rear cutter to mow the lawn; a drive axle is installed on the frame, and the drive motor is connected to the drive axle.

[0012] By adopting the above technical solution, the drive axle transmits the power of the drive motor to the steering wheel of the lawn mower, thereby realizing the overall operation of the lawn mower. The drive axle can effectively ensure the durability and reliability of the lawn mower during operation, which is conducive to ensuring the stability of the lawn mower during lawn mowing, thereby improving the effect of lawn mowing by the lawn mower. There are three reel motors in total, and the three reel motors are fastened to the frame of the lawn mower by corresponding fastening bolts. The three reel motors correspond to the front right reel, the front left reel and the rear reel respectively. When mowing the lawn, turn on the corresponding reel motor according to the specific position of mowing the lawn.

[0013] Preferably, the drive system further comprises a steering motor, and the steering motor is connected to the steering wheel of the lawn mower.

[0014] By adopting the above technical solution, the steering motor is used to realize wire control steering, and the lawn mower can be driven and mowed automatically without adding additional equipment. The steering motor can provide precise steering control for the rotation of the entire frame, reduce the operator's physical exertion, and make the steering system more responsive and more flexible, which is conducive to stable steering feedback, thereby effectively reducing the risk of operating errors.

[0015] Preferably, the rear roller is mounted on the frame in a sliding manner in a horizontal direction.

[0016] By adopting the above technical solution, the rear reel on the lawn mower frame can be completely swung out of the vehicle, making it easier for technicians to adjust the cutter, sharpen the cutter, and perform daily maintenance on the rear reel, making it easier to operate and providing a better experience. When the rear reel needs to be repaired and maintained, it can be directly slid outside the vehicle for corresponding maintenance, which can simplify the maintenance process and improve work efficiency. At the same time, the design is easy to access, which can effectively reduce manpower and time costs. Operators can avoid working in narrow spaces, which helps reduce the risk of injury to workers.

[0017] Preferably, a slide rail is installed on the frame in a horizontal direction at the position of the rear roller, the rear roller is connected to the slide rail via a corresponding mounting frame, and a latch for locking the slide rail is provided on the frame.

[0018] By adopting the above technical solution, when the rear reel needs to be repaired and maintained, the operator can directly pull the rear reel out of the vehicle through the slide rail, and then carry out the corresponding repair and maintenance. After the rear reel is repaired and maintained, the slide rail is slid into the frame, and when the rear reel reaches the corresponding position, the slide rail is locked by the latch, thereby effectively preventing the rear reel from shaking during lawn mowing, thereby ensuring the lawn mowing effect of the lawn mower.

[0019] Preferably, the front right roller, the front left roller and the rear roller are all arranged to be lifted and lowered in the vertical direction, and the lifting and lowering of the front right roller, the front left roller and the rear roller are arranged independently.

[0020] By adopting the above technical solution, the three sets of reels are set to be independently electrically raised and lowered, so that the lawn mower can support multiple mowing modes, which is conducive to providing more flexible operation options. At the same time, the height of the corresponding front right reel, front left reel and rear reel can be adjusted according to different positions and heights of the lawn, which is conducive to ensuring a uniform mowing effect and adapting to different grass conditions and mowing heights.

[0021] Preferably, the front right roller, the front left roller and the rear roller are all mounted on the frame through corresponding mounting frames, an electric push rod is provided on the frame, and a waist-shaped hole is opened on the mounting frame, the movable end of the electric push rod is connected to the waist-shaped hole through a pin, and the fixed end of the electric push rod is connected to the frame through a pin.

[0022] By adopting the above technical solution, the electric push rod is used to lift and lower in the vertical direction, so that the three sets of rollers cooperate with the electronic control, and various mowing modes can be easily achieved.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The frame adopts modular design, which is convenient for equipment maintenance and parts replacement. The lithium battery power system is composed of a high-capacity lithium battery pack, which, together with a high-efficiency motor, can effectively improve the equipment's battery life and provide stable power output. This setting method uses the lithium battery power system to enable the lawn mower to be driven by pure electricity during lawn mowing, changing the original hydraulic drive mode of the lawn mower, thereby effectively avoiding the pollution of the lawn caused by oil leakage during the operation of the lawn mower.

Compared with the original gasoline engine, the pure electric drive does not require manual adjustment of the choke and throttle during the operation of the lawn mower, and can move forward and backward with a single pedal, greatly reducing the difficulty of controlling the lawn mower. The use of new energy technology of the lithium battery power system can achieve zero emission of pollutants from the lawn mower, and zero emission of equipment operation, thereby meeting modern environmental protection requirements. At the same time, compared with fuel drive, electric drive has significantly reduced noise, which is suitable for use in residential areas and places with high requirements for quiet environment.

This allows the rear reel on the frame of the lawn mower to be completely swung out of the vehicle, making it convenient for technicians to adjust the cutter, sharpen the knife, and perform daily maintenance on the rear reel, making it easier to operate and providing a better experience. When the rear reel needs to be repaired and maintained, the rear reel can be directly slid outside the vehicle for corresponding maintenance, which can simplify the maintenance process and improve work efficiency. At the same time, the design is easy to access, which can effectively reduce manpower and time costs. Operators can avoid working in narrow spaces, which is conducive to reducing the risk of injury to workers. The drive motor, reel motor, and steering motor are used as the drive system. The motor drive has instant response capabilities. Compared with the shortcomings of traditional equipment with cumbersome adjustments, low accuracy, and limited gears, the motor of new energy equipment can effectively achieve precise control, which can greatly improve the work efficiency of the lawn mower. The use of motor drive can also eliminate the complex structure of the internal combustion engine, which is conducive to reducing the wear of mechanical parts and effectively reducing the probability of failure of the lawn mower.

The advanced lithium battery pack increases the battery life of the lawn mower equipment and can meet the long-term lawn maintenance needs. Compared with the original gasoline engine, the pure electric drive does not require manual adjustment of the choke and throttle during operation, and can move forward and backward with a single pedal, greatly reducing the difficulty of controlling the lawn mower. The use of lithium battery power system new energy technology can achieve zero emission of pollutants from the lawn mower, and zero emission of equipment operation, thereby meeting modern environmental protection requirements. At the same time, the electric drive significantly reduces the noise compared to the fuel drive, and is suitable for use in residential areas and places with high requirements for quiet environment. The new energy equipment of the lithium battery power system abandons the traditional internal combustion engine and liquid mechanical transmission system, avoids the leakage of coolant, lubricating oil or hydraulic oil, and is conducive to protecting the lawn from pollution. And there is no need to replace consumable parts such as engine oil, spark plugs, and air filters, and the daily maintenance cost is significantly reduced.

[0037] Specifically, refer to Figure 1 and Figure 2, the lawn mowing system includes a front right cutter 2, a front left cutter 3, and a rear cutter 4. The front right cutter 2 and the front left cutter 3 are distributed on the left and right sides of the front end of the frame 1, and the rear cutter 4 is distributed at a position near the rear end of the frame 1. The front right cutter 2, the front left cutter 3, and the rear cutter 4 are integrally distributed on the frame 1 in a "pin" - shaped structure. The drive system controls the front right cutter 2, the front left cutter 3, and the rear cutter 4 to mow the lawn. This enables the front right cutter 2, the front left cutter 3, and the rear cutter 4 to mow different positions of the lawn simultaneously when specifically mowing the lawn, which is conducive to improving the efficiency of the lawn mower in mowing the lawn. At the same time, by using the three groups of blades of the front right cutter 2, the front left cutter 3, and the rear cutter 4 to mow the lawn, the lawn mower can support multiple mowing modes, providing more flexible operation options for lawn mowing.

[0038] Specifically, referring to Figure 1 , Figure 2 and Figure 3 , the drive system includes a drive motor 5, a cutter motor 6, and a steering motor 8. The drive motor 5 is used to drive the overall operation of the frame 1, the cutter motor 6 is used to drive the corresponding front right cutter 2, front left cutter 3, and rear cutter 4 to mow the lawn, and the steering motor 8 is used to assist the steering wheel of the lawn mower to rotate.

[0039] Specifically, referring to Figure 1 , Figure 2 and Figure 3 , the drive motor 5 is fastened to the frame 1 through corresponding fastening bolts. A drive axle 7 is installed on the lawn mower frame 1, and the drive motor 5 is connected to the drive axle 7. The drive axle 7 transmits the power of the drive motor 5 to the steering wheel of the lawn mower, thereby realizing the overall operation of the lawn mower. Using the drive axle 7 can effectively ensure the durability and reliability during the operation of the lawn mower, which is conducive to ensuring the stability during the lawn mowing process of the lawn mower, thereby improving the effect of the lawn mower in mowing the lawn.

[0040] Specifically, there are three cutter motors 6 in total. The three cutter motors 6 are all fastened to the frame 1 of the lawn mower through corresponding fastening bolts, and the three cutter motors 6 respectively correspond to the front right cutter 2, the front left cutter 3, and the rear cutter 4. When specifically mowing the lawn, just turn on the corresponding cutter motor 6 according to the specific position of the lawn to be mowed.

[0041] Specifically, the steering motor 8 is connected to the steering wheel of the lawn mower. By using the steering motor 8, wire - controlled steering is realized, so that the automatic driving mowing of the lawn mower can be achieved without adding additional equipment. The steering motor 8 can provide precise steering control for the overall rotation of the frame 1, reduce the physical consumption of the operator, and make the steering system respond more sensitively and turn more flexibly, which is conducive to stable steering feedback, thereby effectively reducing the risk of operation errors.

Compared with the shortcomings of traditional equipment, which are cumbersome to adjust, low in precision and limited gears, the motor of the new energy equipment can effectively achieve precise control, thereby greatly improving the working efficiency of the lawn mower. The use of motor drive can also eliminate the complex structure of the internal combustion engine, which is conducive to reducing the wear of mechanical parts and effectively reducing the probability of failure of the lawn mower. At the same time, there is no need to replace consumable parts such as engine oil, spark plugs, and air filters, and the daily maintenance cost is significantly reduced. In addition, the motor runs smoothly, vibrates less, and the wear rate of parts is slowed down, which can effectively extend the equipment life of the lawn mower.

[0043] Furthermore, in this embodiment, the rear cutter 4 is slidably mounted on the frame 1 in the horizontal direction, so that the rear cutter 4 on the frame 1 of the lawn mower can be completely swung out of the vehicle, thereby facilitating the technicians to adjust the cutter on the rear cutter 4, sharpen the cutter, and perform daily maintenance, making the operation more convenient and providing a better experience. When the rear cutter 4 needs to be maintained, the rear cutter 4 can be directly slid outside the vehicle for corresponding maintenance, thereby simplifying the maintenance process and improving work efficiency. At the same time, the design is easy to access, which can effectively reduce manpower and time costs, and operators can avoid working in narrow spaces, thereby helping to reduce the risk of injury to workers.

When the rear cutter 4 needs to be repaired and maintained, the operator can directly pull the rear cutter 4 out of the vehicle from the frame 1 through the slide rail 9, and then perform the corresponding repair and maintenance. After the rear cutter 4 is repaired and maintained, the slide rail 9 is slid into the frame 1. When the rear cutter 4 reaches the corresponding position, the slide rail 9 is locked by the latch 10, thereby effectively preventing the rear cutter 4 from shaking during the lawn mowing process, thereby ensuring the lawn mowing effect of the lawn mower.

[0045] Furthermore, in this embodiment, the front right roller 2, the front left roller 3 and the rear roller 4 are all set to be lifted and lowered in the vertical direction, and the lifting and lowering of the front right roller 2, the front left roller 3 and the rear roller 4 are set independently. The three groups of rollers are set to be independently electrically lifted and lowered, so that the lawn mower can support multiple mowing modes, which is conducive to providing more flexible operation options. At the same time, the height of the corresponding front right roller 2, the front left roller 3 and the rear roller 4 can be adjusted according to different positions and heights of the lawn, which is conducive to ensuring a uniform mowing effect and adapting to different grass conditions and mowing heights.
