TECHNICAL FIELD
[0001] The present application relates to the field of lawn mowers, in particular to a lawn mower robot wiring structure and an intelligent lawn mower. BACKGROUND
[0002] An intelligent lawn mower is an automatic working device that autonomously moves and performs a mowing task in a set area, usually including a vehicle body and a shell. The shell is supported above the vehicle body and can move relative to the vehicle body. By setting sensors for detecting relative motion between the vehicle body and the shell, collision events and lifting events can be detected. These sensors usually include collision sensors for detecting collision events and lifting sensors for detecting shell lifting.
[0003] The existing machine usually has a certain activity space between the shell and the vehicle body. Electronic components on the shell and the interior of the vehicle body need to be connected by a wire. Usually, in order to avoid damage to the wire when the shell and the vehicle body move relative to each other, a certain amount of excess wire needs to be left between the shell and the vehicle body. However, this method leaves a part of the excess wire between the shell and the vehicle body, resulting in untidy wiring. Moreover, the excess wire left is long and cannot be fixed. During the operation of the machine, the excess wire freely moves between the shell and the vehicle body, which may cause unpredictable damage.
[0004] Therefore, it is necessary to improve the wiring structure of the existing intelligent lawn mower. SUMMARY
[0005] In view of the above technical problems, the present application provides a lawn mower robot wiring structure. With the wiring structure, the wire does not need to have too much excess between the shell and the vehicle body. When the shell and the vehicle body move relative to each other, the wire moves less and is less likely to be damaged. Moreover, during the operation of the machine, the wire is basically in a state of being limited and closed protection, and has a small activity space and is less likely to be damaged.

[0084] The car body 100 and the shell 200 are relatively movably connected, and the shell 200 can swing up and down within a small range;
[0085] The car body 100 is provided with a connecting seat 110 at the top rear end, which is used for rotatingly connecting the shell 200.
[0086] The wiring portion 9 is arranged on the shell near the hinge structure;
[0087] The wire slot 8 is arranged on the outer side of the shell, and the electronic devices arranged on the inner side of the shell are led from the first wire hole 7 on the inner side of the shell to the outer side of the shell, embedded in the wire slot 8, and then connected with the wires led from the trolley through the connecting terminals 10 at the wiring portion 9.
[0088] As a preferred technical solution of the present embodiment, an opening is arranged on the shell at the wiring portion, which is used for leading the wires into the inner side of the shell and leading them into the trolley through the opening, and a waterproof structure is arranged at the opening.
[0089] As a preferred technical solution of the present embodiment, the wiring portion is arranged on the outer side of the shell, and all the connecting terminals are arranged in the wiring portion.

[0100] A second sensing element 120 is provided at the front of the vehicle body 100. The sensing element can be set on the top surface of the vehicle body 110 or inside the vehicle body 110, close to the top of the vehicle body.
[0101] The measured element is disposed inside the first housing corresponding to the second sensing component 120;
[0102] In this embodiment, the second sensing component 120 is a Hall element, and the first sensing component 215 is a magnet.
[0103] In this embodiment, most of the wiring is located between the first and second housings, completely enclosed by both. During machine operation, the wiring harness is protected by the two housings, preventing contact with the outside world and reducing the risk of damage. Simultaneously, the wiring harness is secured by wire channels or fixing parts along its route from the sensor to the wiring terminal. This fixed wiring does not move arbitrarily during machine operation, clearly defining the wiring path and keeping the wiring inside the housings neat. Using this solution, all wiring allowance and movement occur within the wiring terminal. During machine operation, the wiring terminal is also a small, enclosed area composed of the first and second housings, making the wiring and connectors less susceptible to damage. The connectors are also less likely to be contaminated by rainwater, grass clippings, mud, etc. Example
[0104] Based on Embodiments 1 and 2, this embodiment further includes a tension connector between the vehicle body 100 and the housing 200.

[0107] A cavity 302 is provided in the middle of the seat body;
[0108] The bottom of the base 301 is provided with a first opening 307 and a second opening 309. The second opening is a strip-shaped opening offset from the axis of the pin hole mounting position. The diameter of the first opening is smaller than the length of the pin, and the length of the second opening is greater than the length of the pin.
[0109] In actual installation, the pin is inserted into the pin hole, the stretching rod 304 is stretched from the first opening, and is deflected by a certain angle so that the pin is stretched from the second opening, one end of the pin hole 305 on the whole stretching block enters the cavity 302, then the seat body 301 is connected with the vehicle body 100, the upper end connecting seat 306 of the stretching rod is connected with the connecting seat 216 on the first shell, at this time, the pin and the second opening exist an included angle, and in the moving process of the stretching rod, the lower end is always in the cavity under the limiting action of the pin.
[0110] The connecting seat 216 on the first shell has the structure as above, the upper end of the stretching rod 304 is inserted into the connecting groove and is limited by the shape, the stretching rod cannot be rotated after installation, but can move up and down relative to the seat body, and has a certain displacement space in the front-back and left-right directions.
