Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to a deck vertical lifting structure for a remote-controlled lawnmower. Background Technology

[0002] As people's demands for the quality of their living environment increase, lawn mowers are being used more and more widely in areas such as lawn maintenance and garden trimming. In particular, remote-controlled lawn mowers are favored by users because of their convenient operation and ability to adapt to complex terrain.

[0003] However, existing remote-controlled lawnmowers have many shortcomings in terms of deck vertical lifting technology:

[0004] 1. Complex Lifting Structure: Traditional lawnmower deck lifting structures often consist of multiple complex mechanical components, which not only increases manufacturing costs but also makes them prone to malfunctions and difficult to maintain. For example, some lawnmowers using hydraulic lifting systems require numerous components such as oil pumps, cylinders, and oil pipes, making the system complex. Once problems such as oil leaks occur, repair costs are high and time-consuming.

[0005] 2. Low lifting accuracy: It is difficult to precisely control the lifting height of the deck, resulting in uneven mowing height and affecting the quality of lawn trimming. This lack of accuracy is particularly prominent in places with strict requirements for lawn height, such as golf courses and upscale residential areas.

[0006] 3. Unresponsive remote control: Delays in remote signal transmission prevent accurate real-time control of deck raising and lowering, reducing work efficiency and user experience. When terrain changes necessitate timely adjustments to deck height, delayed response can damage lawnmower blades or result in poor mowing performance.

[0007] In conclusion, existing remote-controlled lawnmower deck vertical lifting technology cannot meet the market's demand for efficient, precise, and stable lawnmowing operations, and a new technology is urgently needed to solve these problems. Utility Model Content

[0008] This utility model provides a vertical lifting structure for the deck of a remote-controlled lawnmower to solve the problems of complex lifting structures, low precision, and unresponsive remote control in the prior art. It enables precise, fast, and stable lifting of the lawnmower deck, thereby improving the quality and efficiency of lawnmower operations.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a deck vertical lifting structure for a remote-controlled lawnmower, comprising a body, a deck hanging plate, an electric push rod, a transmission assembly, and a reset assembly. The body is a frame structure, with fixed plates fixedly connected to the upper part of both sides of the tail. The electric push rod is fixedly connected to the front end of the fixed plate. The output end of the electric push rod is fixedly connected to the transmission assembly below via a U-shaped seat. The lower part of the transmission assembly is fixedly connected to the edge of the deck hanging plate. The middle part of the reset assembly is fixedly connected to the inner side of the body, and the bottom part is fixedly connected to the upper surface of the deck hanging plate. The electric push rod converts the horizontal driving force into a vertical force through the transmission assembly and transmits it to the deck hanging plate, thereby lowering or raising the deck hanging plate. The reset assembly enables the deck hanging plate to quickly reset when it needs to be raised after lowering.

[0010] Furthermore, it also includes a controller, which is equipped with a microprocessor and a wireless communication module. The controller is installed on the machine body or deck hanging plate and is wirelessly connected to the remote control of the electric push rod and the lawnmower, respectively.

[0011] Furthermore, the transmission assembly includes a first transmission link, a second transmission link, a third transmission link, and a mounting base. The output end of the electric push rod is fixedly connected to the first transmission link, which is horizontally arranged below, via a U-shaped base. The lower ends of the first transmission link are rotatably connected to one end of the second transmission link, and the middle of the second transmission link is rotatably connected to the machine body via a rotating shaft. The other end of the second transmission link is rotatably connected to one end of the third transmission link, and the other end of the third transmission link is rotatably connected to the top of the L-shaped mounting base. The bottom of the mounting base is fixedly connected to the deck hanging plate.

[0012] Furthermore, the reset assembly includes a guide rod, a limiting nut, a reset spring, a second U-shaped seat, and a guide tube. The base plate of the second U-shaped seat is fixedly connected to the inner side of the machine body, and the guide tube passes through the vertical plate below the second U-shaped seat and is fixedly connected to the lower surface of the vertical plate above the second U-shaped seat. A reset spring is provided above the second U-shaped seat. One end of the guide rod is threaded, and the other end of the guide rod passes through the reset spring, the second U-shaped seat, and the guide tube in sequence, and is finally fixedly connected to the upper surface of the deck hanger. The threaded end of the guide rod is threadedly connected to the limiting nut.

[0013] Furthermore, it also includes a buffer plate, the upper and lower surfaces of which are fixedly connected to the guide rod and the deck hanger, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The vertical lifting structure of the deck of this remote-controlled lawnmower has the following advantages:

[0015] Improved mowing efficiency: The deck height can be quickly adjusted according to different lawn conditions and mowing needs, adapting to various complex terrains and reducing the time and effort required for manual adjustments, making mowing more efficient. For example, in orchards, when encountering lawns around fruit trees of different heights, the mowing height can be quickly adjusted to improve weeding efficiency.

[0016] Improving lawn mowing quality: Precise control of mowing height ensures a consistent lawn or turf height after mowing, enhancing the smoothness and aesthetics of the lawn. For example, in places like golf courses where lawn smoothness is crucial, precise vertical control of the mowing platform can achieve high-quality mowing results.

[0017] Protecting lawnmower components: When encountering uneven ground or obstacles, the deck vertical lifting technology can adjust the height in time to avoid the lawnmower blade from colliding with the ground or obstacles, thereby reducing the wear and damage of the lawnmower blade and other components, and extending the service life of the lawnmower.

[0018] Enhanced terrain adaptability: Whether on slopes, uneven terrain, or undulating grass, the lawnmower can maintain the appropriate mowing height by vertically raising and lowering the deck, making mowing work unrestricted by terrain and expanding the range of applications of the lawnmower.

[0019] Reduced operational difficulty: Operators can easily control the vertical raising and lowering of the deck via remote control, eliminating the need for manual adjustments or difficult operations in complex terrain. This reduces operational difficulty and labor intensity, while improving operational safety and comfort.

[0020] Reduced structural space: Vertical lifting saves space for forward and backward movement of the deck, reduces the size of the machine structure, making it more maneuverable, and makes the structure more compact and robust, saving manufacturing costs and resources.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment provides a technical solution: such as Figure 1-5 The aforementioned remote-controlled lawnmower's deck vertical lifting structure includes a body 1, a deck hanging plate 2, an electric push rod 3, a transmission assembly 6, and a reset assembly 7. The body 1 is a frame structure, with fixed plates 4 fixedly connected to the upper part of both rear sides. The electric push rod 3 is fixedly connected to the front end of the fixed plates 4. The output end of the electric push rod 3 is fixedly connected to the transmission assembly 6 below via a U-shaped seat 5. The lower part of the transmission assembly 6 is fixedly connected to the edge of the deck hanging plate 2. The middle part of the reset assembly 7 is fixedly connected to the inner side of the body 1, and the bottom part is fixedly connected to the upper surface of the deck hanging plate 2. The electric push rod 3 converts the horizontal driving force into a vertical force through the transmission assembly 6 and transmits it to the deck hanging plate 2, realizing the lowering or raising of the deck hanging plate 2. The reset assembly 7 realizes the rapid reset of the deck hanging plate 2 when it needs to be raised after lowering. It also includes a controller, which is equipped with a microprocessor and a wireless communication module. The controller is installed on the body 1 or the deck hanging plate 2 and is wirelessly connected to the electric push rod 3 and the lawnmower's remote control, respectively.

[0029] like Figure 2As shown, the transmission assembly 6 includes a first transmission link 61, a second transmission link 62, a third transmission link 63, and a mounting base 64. The output end of the electric push rod 3 is fixedly connected to the first transmission link 61, which is horizontally arranged below, via a U-shaped seat 5. The lower ends of the first transmission link 61 are rotatably connected to one end of the second transmission link 62, and the middle of the second transmission link 62 is rotatably connected to the machine body 1 via a rotating shaft. The other end of the second transmission link 62 is rotatably connected to one end of the third transmission link 63, and the other end of the third transmission link 63 is connected to the L-shaped mounting base. The upper part of the mounting base 64 is rotatably connected, and the bottom of the mounting base 64 is fixedly connected to the deck hoisting plate 2. When the electric push rod 3 extends, it pushes the transmission connecting rod 1 61 forward, thereby causing the inclination of the transmission connecting rod 2 62 to decrease, and indirectly causing the inclination of the transmission connecting rod 3 63 to increase. The deck hoisting plate 2 is then raised through the mounting base 64. When the electric push rod 3 retracts, it pulls the transmission connecting rod 1 61 backward, thereby causing the inclination of the transmission connecting rod 2 62 to increase, and indirectly causing the inclination of the transmission connecting rod 3 63 to decrease. The deck hoisting plate 2 is then lowered through the mounting base 64.

[0030] like Figure 3 As shown, the reset assembly 7 includes a guide rod 71, a limiting nut 72, a reset spring 73, a U-shaped seat 74, and a guide tube 75. The base plate of the U-shaped seat 74 is fixedly connected to the inner side of the body 1, and the guide tube 75 passes through the vertical plate below the U-shaped seat 74 and is fixedly connected to the lower surface of the vertical plate above the U-shaped seat 74. A reset spring 73 is provided above the U-shaped seat 74. One end of the guide rod 71 is threaded, and the other end of the guide rod 71 passes through the reset spring 73, the U-shaped seat 74, and the guide tube 75 in sequence, and is finally fixedly connected to the upper surface of the deck hoisting plate 2. The threaded end of the guide rod 71 is threadedly connected to the limiting nut 72. When the deck hoisting plate 2 descends, it drives the guide rod 71 to move downward. Since the height of the U-shaped seat 74 is fixed, the downward movement of the guide rod 71 causes the reset spring 73 to be compressed. When the deck hoisting plate 2 rises, it pushes the guide rod 71 to move upward, and the rebound force of the reset spring 73 accelerates the reset.

[0031] It also includes a buffer plate 76, the upper and lower surfaces of which are fixedly connected to the guide rod 71 and the deck hanging plate 2, respectively, to disperse the pressure of the guide rod 71 on the deck hanging plate 2 and increase stability.

[0032] The working principle of the deck vertical lifting structure of the remote-controlled lawnmower provided by this utility model is as follows: During operation, the deck is vertically lifted and lowered by a remote control. The electric push rod 3 converts the horizontal driving force into a vertical force through the transmission component 6 and transmits it to the deck hanging plate 2, realizing the lowering or raising of the deck hanging plate 2. The reset component 7 realizes the rapid reset of the deck hanging plate 2 when it needs to be raised after it has been lowered. When the electric push rod 3 extends, it pushes the transmission connecting rod 1 61 forward, thereby reducing the tilt angle of the transmission connecting rod 2 62, and indirectly increasing the tilt angle of the transmission connecting rod 3 63. This causes the deck hanging plate 2 to rise through the mounting base 64. When the electric push rod 3 retracts, it pulls the transmission connecting rod 1 61 backward, thereby increasing the tilt angle of the transmission connecting rod 2 62, and indirectly reducing the tilt angle of the transmission connecting rod 3 63. This causes the deck hanging plate 2 to fall through the mounting base 64. When the deck hoist 2 descends, it causes the guide rod 71 to move downward. Since the height of the U-shaped seat 74 is fixed, the downward movement of the guide rod 71 causes the return spring 73 to be compressed. When the deck hoist 2 rises, it pushes the guide rod 71 upward, and at the same time, due to the rebound force of the return spring 73, it accelerates the return to its original position.

[0033] It is worth noting that the microprocessor disclosed in the above embodiments can be an AT89C4051 microcontroller, the electric actuator 3 can be freely configured according to the actual application scenario, the electric actuator 8 can be a LAM1 electric actuator, and the microprocessor controls the operation of the electric actuator 3 and the wireless communication both adopt methods commonly used in the prior art.

[0034] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
