Problems solved by technology

[0002] Lawn mowers are common garden tools. With the continuous development of science and technology, highly intelligent automatic lawn mowers are becoming more and more common, but there is a common problem with lawn mowers—that is, judging whether the machine is in a normal walking state, the public number The invention patent of CN108427410A discloses a structure for self-moving equipment: the traveling mechanism includes driving wheels and driven wheels, and the state detection device includes at least two magnetic triggers, signal sensors and detection devices. At least two magnetic triggers are arranged on the slave The driving wheel is rotatable with the driven wheel, and the adjacent magnetic triggers have different polarities along the same side of the driven wheel, and the signal sensor senses the magnetic field signal generated by the magnetic trigger and generates an induction signal ; The detection device judges the rotation state of the driven wheel according to the induction signal, thereby judging whether the self-moving device is running normally, but the cost of this structure is relatively high

Embodiment 1

[0024] see Figures 1 to 6 , In the embodiment of the present invention, a roller trapped detection mechanism includes a roller mechanism 50 located under the lawn mower 100; the roller mechanism 50 includes a roller 500, and the roller 500 runs through a roller shaft 53 and is sleeved with the roller shaft 53 Fixed, the roller shaft 53 rotates synchronously with the roller 500; the outer side of the roller shaft 53 is sleeved with a lower cover 51, the lower cover 51 is provided with a wheel shaft hole 512, the roller shaft 53 penetrates the wheel shaft hole 512 and is sleeved with a limit block 56, the roller shaft 53 is provided with an axle slot 530, the axle slot 530 is sleeved and fixed with an axle limit block 56, the outer diameter of the axle limit block 56 is larger than the outer diameter of the axle hole 512, the axle limit block 56 is in contact with the axle hole 512, and the The right end portion of the roller shaft 53 is limited in the lower cover 51 .

Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that: the sensing rod 57 is fixedly connected with a roller fixing frame 58, the roller fixing frame 58 connects and fixes the upper cover 52 with the lawn mower 100, and the upper end of the sensing rod 57 is sleeved with a sensor The measuring rod clamp 59, the upper end of the sensing rod 57 is connected with a Hall element, when the roller 500 of the lawn mower 100 moves normally, the eccentric shaft 531 at the end of the roller shaft 53 drives the swing rod 54 to swing regularly, and the sensing rod 57 The regular signal of the induction sheet 55 can be detected; when the lawn mower 100 is trapped, the roller 500 cannot roll normally, and the induction sheet 55 cannot be swung regularly with the pendulum rod 54, so that the sensing rod 57 cannot detect the regular signal. When the mower 100 is trapped, the user can be notified by other means.

Embodiment 3

Abstract

The invention discloses a roller trapped detection mechanism and a lawnmower having the mechanism. The roller trapped detection mechanism includes a roller mechanism located below the lawn mower; The outer cover is provided with a lower cover, and the right side of the lower cover is fixedly connected with the upper cover by means of bolts. A fan-shaped cavity is formed between the lower cover and the upper cover, and a swing rod is arranged in the fan-shaped cavity; the upper part of the swing rod is nested with an induction piece, and a sensing rod is nested on the upper cover. The present invention is provided with a roller shaft that rotates synchronously with the roller, an eccentric shaft provided on the end surface of the roller shaft, and a swing rod with a swing rod groove and a swing rod hole, so that when the roller rotates normally, the swing rod drives the induction sheet to move in a regular manner. Swing, when in the trapped state, the sensing piece cannot be sensed regularly by the sensing rod, so as to realize the determination of the trapped state and the detection of the trapped state of the roller. The structure is simple and compact, the detection effect is good, and it is convenient for users to use.
