Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 7, a shock absorbing assembly 100 of the present invention includes: a shock-absorbing member 110 having a hollow portion 111 therein; a connector 120 adapted to pass through the hollow portion 111 to mount the shock-absorbing member 110 between the housing 200 and the movable upper cover 300 of the lawn mower; when the movable upper cover and the machine shell generate relative displacement in the horizontal direction, the shock absorption element is extruded to generate deformation elasticity.

The damping member 110 is cylindrical or columniform, one end of which is closed and is provided with a mounting hole 112 with a diameter smaller than that of the hollow part; the connecting member 120 is adapted to be inserted into or out of the hollow portion 111 of the shock-absorbing member 110 through the mounting hole 112, i.e., a space for deformation of the shock-absorbing member is left between the shock-absorbing member and the connecting member. Optionally, the damping element may be made of elastic rubber, so that the deformation mainly comes from the gap, and the self-compression capacity of the damping element can assist in compressing the gap to generate deformation elasticity. In order to fix the shock-absorbing member 110, the connection member 120 includes: a fastener 121 and a mounting post 122 on the movable upper cover 300; the fasteners 121 pass through the mounting holes and are threadably coupled to the mounting posts 122 to secure the suspension element to the mounting posts. The fastening member 121 may be a screw screwed into the mounting post or a threaded sleeve screwed onto the outer side of the mounting post to prevent the damping element from loosening. Of course, it is understood that in other embodiments, the shock absorbing member 110 may be fixedly mounted on the movable upper cover 300 or the housing 200 by other means. The present invention does not limit the fixing and mounting manner of the shock absorbing member 110. In order to make the shock absorbing element meet the assembly and design requirements, preferably, the other end of the shock absorbing element 110 is open and is inclined, and the side of the shock absorbing element 110 close to the movable upper cover is provided with a limit wall 113 to fit the inner wall of the movable upper cover, so as to prevent the shock absorbing element 110 from rotating around the mounting column 122. However, it is understood that in other embodiments, the shock absorbing member 110 may be a spring, torsion spring, tension spring, damping member, or the like of similar construction.

Referring to fig. 2, 3 and 7-8, the present invention further discloses a lawn mower, which comprises a housing 200; a movable upper cover 300 covering the cabinet 200; and a shock-absorbing assembly 100 between the cabinet 200 and the movable upper cover 300; when the movable top cover 300 of the lawn mower and the housing 200 are displaced or have a horizontal relative displacement, the damping member 100 is pressed to generate a deformation elastic force, so as to perform a damping function.

Referring to fig. 2 and 3, the movable upper cover 300 is movably mounted on the housing 200, and when the mower collides, the housing 200 and the movable upper cover 300 can move relatively. In this embodiment, the movable upper cover 300 may be mounted on the housing 200 by an elastic bracket 400. When the mower collides, the elastic bracket 400 is elastically deformed to allow relative displacement between the movable upper cover 300 and the housing 200 in the direction of the collision. The resilient support 400 may be a connection assembly that allows for a certain level of misalignment, such as a spring, a resilient tab, a lift detection assembly, and the like. Of course, it is understood that the movable cover 300 can be movably mounted on the housing 200 by other methods. For example, the movable upper cover 300 may be slidably mounted on the set cover 200 by rails. The present invention does not limit the manner in which the movable upper cover 300 is movably mounted on the housing 200. The shock absorbing assembly 13 is located between the cabinet 200 and the movable upper cover 300. When the mower collides, due to certain inertia and control delay, before the walking component drives the mower to change the walking route, the machine shell and the movable upper cover can continuously generate relative displacement, at the moment, the shock absorption component is extruded between the machine shell 200 and the movable upper cover 300 to generate deformation elasticity to generate deformation, the collision behavior can be slowed down, rigid collision between the machine shell 200 and the movable upper cover 300 is converted into elastic collision, and therefore the effects of buffering and shock absorption are achieved, and the service life of the mower is prolonged. In this embodiment, the shock absorbing assembly 100 is deformed immediately after displacement in the event of a collision. However, it is understood that the shock absorbing assembly 100 may be configured to deform when the relative displacement is greater than a predetermined distance by adjusting the size and mounting position of the shock absorbing assembly in other embodiments.

Referring to fig. 2 and fig. 8-12, the mower further includes a cutting blade assembly 500, a traveling assembly 600, a collision detection assembly 700, and a control assembly 800 (located inside the housing and generally including a processor and its corresponding control circuit and driving circuit) respectively mounted on the housing 200. The cutter assembly 500 comprises a cutter disc 510 driven by a motor, and a mowing blade 520 can be arranged on the cutter disc 510. The walking assembly 600 is used for performing a self-walking function of the lawn mower, and comprises at least one pair of driving wheels 610 and at least one driven wheel 620; two driven wheels 620 are optional in the drawings of this disclosure. The collision detecting assembly 700 is used to detect the relative displacement between the movable cover 300 and the housing 200 and determine whether the mower collides, especially in the horizontal direction. In this embodiment, the collision detecting assembly 700 may be mounted on the cabinet 200. However, it is understood that in other embodiments, the collision detecting assembly 700 may be mounted on the movable cover 300. Referring to fig. 11, the control assembly 800 is used to control the operation of the cutter assembly 500, the walking assembly 600 and the collision detecting assembly 700. The control component 800 may be a control circuit or a single chip.

Optionally, referring to fig. 2, the collision detecting assembly 700 includes: a magnet block 710 on the movable upper cover 300, a hall plate 720 on the casing 200; the magnet block 710 and the hall plate 720 are arranged up and down and keep a certain distance; in the normal driving process of the equipment, when an obstacle is encountered, the movable upper cover 300 stops moving when encountering the obstacle, the walking assembly 600 drives the machine shell 200 to normally drive, displacement change is generated between the magnet 710 and the Hall plate 720, the Hall plate detects the displacement change and feeds a Hall signal back to the control assembly, and the control assembly judges that the machine encounters the obstacle through the Hall signal and sends a corresponding obstacle avoidance instruction.

Specifically, referring to fig. 12, the operation of the lawn mower is as follows:

when the mower needs to work, a designated route of the mower can be set through a control panel of the control assembly or a man-machine interaction machine, and then the walking assembly is started to drive the mower to walk according to the designated route; cutting parameters of the cutting knife assembly, such as the height of a cutting knife, the rotating speed and the like, are set through the control assembly, and then the cutting knife assembly is started to cut grass; when the mower collides in the walking process, the movable upper cover and the machine shell generate relative displacement in the horizontal direction, so that the shock absorption assembly is extruded to generate deformation elasticity to play a shock absorption role, and meanwhile, the collision detection assembly sends a collision signal to the control assembly; the control assembly controls the walking assembly to drive the mower to change the walking route according to the collision signal so as to avoid collision and continue to perform cutting and walking actions.

Compared with the prior art, the mower of the invention has the advantages that the shock absorption assembly 100 is arranged between the movable upper cover 300 and the machine shell 200 for buffering, so that the rigid collision between the movable upper cover 300 and the machine shell 200 is converted into elastic collision, and the purposes of buffering, absorbing shock and prolonging the service life of the machine are achieved.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
