Description

Technical Field

[0001] This utility model relates to the field of lawnmower chassis technology, and in particular to a lawnmower chassis with supporting components. Background Technology

[0002] As an important tool for modern garden maintenance, lawn mowers directly affect the efficiency and quality of garden operations. Currently, most large-width lawn mowers on the market use metal chassis, which, while strong, are heavy and expensive. Some lawn mowers use plastic chassis, which are lightweight but less strong and are generally only suitable for small-width mowers.

[0003] For example, CN216058335U discloses a chassis with supporting components, including: a plastic chassis, a volute reinforcement member disposed along the volute portion of the plastic chassis, and a power reinforcement member disposed in a central opening in the plastic chassis for mounting a power head. The volute reinforcement member is disposed on the power head mounting surface of the plastic chassis, and the power reinforcement member is disposed within the central opening. The chassis with supporting components provided in this application is a plastic chassis, which significantly reduces costs compared to metal chassis and is lightweight. By providing a volute reinforcement member in the volute portion of the plastic chassis, the strength of the volute portion can be increased. By providing a power reinforcement member in the central opening, the connection strength of the power head can be increased. The overall strength of the chassis is improved through these two reinforcement methods.

[0004] However, in the existing technology, the strength of the volute can be increased by setting a volute reinforcement in the volute part of the plastic chassis, and the connection strength of the power head can be increased by setting a power reinforcement in the center hole, thus improving the overall strength of the chassis. Due to the large weight of the whole machine, when cleaning and maintaining the chassis, it is necessary to manually move one side of the chassis to make it tilt up in order to complete the work. This maintenance method is not only laborious and inefficient, but also poses a safety hazard, as it is easy to cause personal injury due to the chassis suddenly falling back. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, the overall weight of the machine is large, and when cleaning and maintaining the chassis, it is necessary to manually move one side of the chassis to tilt it up in order to complete the work. This maintenance method is not only laborious and inefficient, but also poses a safety hazard, as it is easy to cause personal injury if the chassis suddenly falls back.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lawnmower chassis with supporting components, comprising a chassis body, with movable wheels arranged at the four corners of the chassis body, a grass collection bag arranged at one end of the chassis body, and a supporting structure arranged in the middle of the chassis body, the supporting structure comprising a lifting component and a supporting component, the lifting component comprising a supporting seat, the supporting seat being fixed to both sides of the chassis body.

[0007] In a preferred embodiment, a first sliding groove is provided in the middle of the bottom end of the support base, and a reciprocating screw is rotatably connected inside the first sliding groove. One end of the reciprocating screw passes through the support base, and the other end of the reciprocating screw located outside the support base is fixedly connected to a first turntable.

[0008] In a preferred embodiment, the support base is slidably connected to a first slider inside the first groove. The first slider is threadedly connected to a reciprocating lead screw. A first connector is fixedly connected to the bottom end of the first slider. A lifting rod is rotatably connected to the middle of the first connector. A second connector is rotatably connected to the end of the lifting rod away from the first connector. A support plate is fixedly connected to the bottom end of the second connector.

[0009] In a preferred embodiment, the support assembly includes a bracket with two second sliding grooves in the middle and limit grooves on both sides of the middle of the second sliding grooves. The support base is slidably connected to a support column inside the second sliding groove, and the support column is slidably connected to the inside of the second sliding groove.

[0010] In a preferred embodiment, a limiting block is fixedly connected to the middle of the top of the support column, the limiting block is slidably connected to the limiting groove, a second support rod is slidably connected to the bottom of the support column, and a second slider is fixedly connected to the top of the support column, the second slider being slidably connected to the bracket.

[0011] In a preferred embodiment, the top end of the second support rod is threadedly connected to a first lead screw, the top end of the first lead screw rotatably passes through the support column and the second slider, and the first lead screw is fixedly connected to a second turntable at the top end of the second slider.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, when cleaning and maintaining the bottom of the chassis body, rotating the first turntable drives the reciprocating screw to rotate, which in turn drives the first slider to move closer together. The movement of the first slider causes the first connector to move closer together, and the first connector pushes the lifting rod to move downward. The lifting rod then pushes the second connector to move, and the second connector pushes the support plate to gradually contact the ground. Subsequently, the continuous compression of the lifting rod causes the chassis body to be lifted. When the chassis body is lifted to the top, the first turntable stops rotating. At this time, the chassis body is in a suspended state, and workers can clean and maintain the bottom of the chassis body without the need for personnel to move it, saving time and effort and improving safety.

[0014] The drive structure is located at the top center of the chassis body, and most of the weight is concentrated in the middle of the chassis body. Therefore, the second sliders are pushed closer together, and the second sliders drive the second support rod to contact the drive structure at the top of the chassis body. Then, the second turntable is rotated, which drives the first lead screw to rotate. The first lead screw drives the second support rod to move upward. The bottom end of the second support rod supports the drive structure, thereby distributing the weight of the drive structure and improving the stability of the chassis body.

[0023] 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.

[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a lawnmower chassis with supporting components, including a chassis body 1, with moving wheels 2 at the four corners of the chassis body 1, a grass collection bag 3 at one end of the chassis body 1, and a supporting structure in the middle of the chassis body 1. The supporting structure includes a lifting component and a supporting component. The lifting component includes a supporting seat 41, which is fixed to both sides of the chassis body 1.

[0025] like Figure 5 and Figure 6 As shown, a first groove 411 is provided in the middle of the bottom end of the support base 41. A reciprocating screw 412 is rotatably connected inside the first groove 411. One end of the reciprocating screw 412 passes through the support base 41. A first turntable 413 is fixedly connected to the end of the reciprocating screw 412 located outside the support base 41. A first slider 414 is slidably connected inside the first groove 411 of the support base 41. The first slider 414 is threadedly connected to the reciprocating screw 412. A first connector 415 is fixedly connected to the bottom end of the first slider 414. A lifting rod 416 is rotatably connected to the middle of the first connector 415. A second connector 417 is rotatably connected to the end of the lifting rod 416 away from the first connector 415. A support plate 418 is fixedly connected to the bottom end of the second connector 417.

[0026] In this embodiment, when it is necessary to clean and maintain the bottom of the chassis body 1, the first turntable 413 is rotated to drive the reciprocating screw 412 to rotate. The reciprocating screw 412 drives the first slider 414 to move closer to each other. The movement of the first slider 414 drives the first connector 415 to move closer to each other. The first connector 415 pushes the lifting rod 416 to move downward. The lifting rod 416 pushes the second connector 417 to move. The second connector 417 pushes the support plate 418 to gradually contact the ground. Subsequently, the continuous compression of the lifting rod 416 causes the chassis body 1 to be supported. When the chassis body 1 is supported to the top, the first turntable 413 stops rotating. At this time, the chassis body 1 is in a suspended state, and the staff can clean and maintain the bottom of the chassis body 1. Therefore, no personnel need to move it, saving time and effort and improving safety.

[0027] like Figure 1 - Figure 4As shown, the support assembly includes a bracket 42. Two second sliding grooves 421 are formed in the middle of the bracket 42. Limiting grooves 422 are formed on both sides of the middle of the second sliding grooves 421. A support base 41 is slidably connected to a support column 423 inside the second sliding grooves 421. The support column 423 is slidably connected to the inside of the second sliding grooves 421. A limiting block 424 is fixedly connected to the middle of the top of the support column 423. The limiting block 424 is slidably connected to the limiting groove 422. A second support rod 425 is slidably connected to the bottom of the support column 423. A second slider 427 is fixedly connected to the top of the support column 423. The second slider 427 is slidably connected to the bracket 42. A first lead screw 426 is threadedly connected to the top of the second support rod 425. The top of the first lead screw 426 rotates through the support column 423 and the second slider 427. A second turntable 428 is fixedly connected to the top of the second slider 427.

[0028] In this embodiment, the drive structure is located at the middle of the top of the chassis body 1, and most of the weight is concentrated in the middle of the chassis body 1. In use, the second sliders 427 are pushed closer to each other, and the second sliders 427 drive the second support rods 425 to contact the two sides of the bottom of the drive structure at the top of the chassis body 1. Then, the second turntable 428 is rotated to drive the first lead screw 426 to rotate. The first lead screw 426 drives the second support rods 425 to move upward. The bottom end of the second support rods 425 supports the drive structure, thereby distributing the weight of the drive structure and improving the stability of the chassis body 1.

[0029] Working principle: First, the drive structure is located at the center of the top of the chassis body 1, and most of the weight is concentrated in the center of the chassis body 1. During use, pushing the second slider 427 closer together causes the second support rod 425 to contact the two sides of the bottom of the drive structure at the top of the chassis body 1. Then, rotating the second turntable 428 causes the first lead screw 426 to rotate, which in turn moves the second support rod 425 upwards. The bottom end of the second support rod 425 supports the drive structure, thus distributing the weight of the drive structure and improving the stability of the chassis body 1. When cleaning or maintaining the bottom of the chassis body 1, rotating the first turntable 413 drives the reciprocating lead screw... Rotating rod 412 causes reciprocating screw 412 to drive first slider 414 to move closer together. The movement of first slider 414 causes first connector 415 to move closer together. First connector 415 pushes lifting rod 416 downward. Lifting rod 416 pushes second connector 417 to move. Second connector 417 pushes support plate 418 to gradually contact the ground. Subsequently, the continuous compression of lifting rod 416 causes chassis body 1 to be supported. When chassis body 1 is supported to the top, first turntable 413 stops rotating. At this time, chassis body 1 is in a suspended state, and workers can clean and maintain the bottom of chassis body 1 without moving it, saving time and effort and improving safety.
