Abstract
The utility model discloses a substitute structure of an intelligent mower pressure sensor, which comprises a base and an upper cover. A connecting post is arranged on the top of one side of the base; a connecting groove corresponding to the connecting post is arranged at the bottom of the upper cover; an elastic part is sleeved on the connecting post; two ends of the elastic part are respectively abutted to the connecting post and the connecting groove; an on-off control structure of a mower is arranged on the top of the other side of the base; the bottom of the upper cover controls the working state of the mower through the on-off control structure; the on-off control structure includes two contact pieces fixedly connected onto the base; the two contact pieces isolated by an insulating part extend to the lower portion of the bottom of the upper cover; and the bottom of the upper cover pushes the two contact pieces to mutually contact. The substitute structure of the intelligent mower pressure sensor effectively realizes pressure sensing effect, realizes on and off state of the mower when pressure reaches a limited value, and has a simple discrimination circuit with only switch on and off conditions. The cost of the substitute structure is lower than that of a sensor, and simultaneously the mechanical portion of the substitute structure is simple and reliable in structure, and simple and convenient in assembly.
Description
Technical field
The utility model relates to the pressure sensor of intelligent grass-removing.
Background technology
Along with the increasingly mature of grass-removing robot technology and some safety requirements, pressure sensor just progressively is applied in the intelligent grass-removing.China national Department of Intellectual Property has announced one on September 26th, 2007 and has been called pressure sensor, notification number is the utility model patent of CN200952967, according to its specification in conjunction with Figure of description as can be known: this pressure sensor comprises loam cake, pcb board and the pressure chip that is connected with pcb board point of being with exploration hole, pressure chip is by pcb board and loam cake clamping, the induction terminal of pressure chip is corresponding with the pressure exploration hole position of loam cake, on cover and be provided with Elastic buckle, pcb board is provided with the hole clipping suitable with Elastic buckle; The buckle of fixing in hole clipping fixed loam cake, pcb board and pressure chip three relative position.But this pressure sensor poor reliability, complex structure is installed inconvenience, and needs more complicated judging circuit, and cost is also high.
The utility model content
The purpose of this utility model is to provide the alternative structure of intelligent grass-removing pressure sensor, can effectively solve existing mower pressure sensor poor reliability, the problem that complex structure and cost are high.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the alternative structure of intelligent grass-removing pressure sensor, comprise base and loam cake, it is characterized in that: the top of base one side is provided with joint pin, the loam cake bottom is provided with the link slot corresponding with joint pin, be socketed with elastic component on the joint pin, the two ends of elastic component prop up joint pin and link slot respectively, the top of base opposite side is provided with the break-make control structure of mower, and the loam cake bottom is by the duty of break-make control structure control mower.
Further, the break-make control structure comprises that two are fixedly connected on contact chip on the base, isolates by insulating part between two contact chips, and contact chip extends to the below of loam cake bottom, and the loam cake bottom promotes two contact chips and contacts.
Further, base is provided with internal thread hole and corresponding fastening bolt, and fastening bolt passes two contact chips connection internal thread holes realization contact chips from top to bottom and fixes, and fixed form is reliable,
Further, two contact chips are drawn a wire respectively.
Further, the joint pin center is provided with pilot hole, is provided with the lead corresponding with pilot hole in the base, by this guide frame, guarantees the reliability that loam cake moves up and down, and also limits the horizontal movement of loam cake.
Preferably, elastic component adopts spring or rubber elastomer, and reliable operation is cheap.
The utility model is owing to adopted technique scheme, effectively realized the pressure sensing effect, when reaching limit value, realizes pressure the break-make of mower, this alternative structure judging circuit is simple, have only two kinds of situations of switch on and off, cost is cheap than sensor, and the mechanical part of this alternative structure is simple and reliable for structure simultaneously, assembles easy.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the alternative structure of the utility model intelligent grass-removing pressure sensor;
Fig. 2 is the structural representation behind Fig. 1 pressurized.
Embodiment
Be the alternative structure of the utility model intelligent grass-removing pressure sensor as depicted in figs. 1 and 2, comprise base 1 and loam cake 2, the top of base 1 one sides is provided with joint pin 11, loam cake 2 bottoms are provided with the link slot 21 corresponding with joint pin 11, be socketed with elastic component on the joint pin 11, elastic component adopts spring 3 or rubber elastomer, and the two ends of spring 3 prop up joint pin 11 and link slot 21 ends respectively, and the vertical direction between base 1 and the loam cake 2 leaves certain stroke and is used for the flexible of spring 3; The top of base 1 opposite side is provided with the break-make control structure of mower, and loam cake 2 bottoms are by the duty of break-make control structure control mower.The break-make control structure comprises that two are fixedly connected on contact chip 4 on the base 1, two contact chips 4 are drawn a wire respectively, base 1 is provided with internal thread hole 13 and corresponding fastening bolt 5, and fastening bolt 5 passes two contact chips, 4 connection internal thread holes 13 from top to bottom and realizes that contact chips 4 are fixing.Isolate by insulating part between two contact chips 4, contact chip 4 extends to the below of loam cake 2 bottoms, loam cake 2 bottoms promote two contact chips 4 and contact, joint pin 11 centers are provided with pilot hole 12, be provided with the lead 22 corresponding in the base 1, when playing the guiding role, can limit loam cake 2 and move in the certain limit in the horizontal direction with pilot hole 12.A plurality of these alternative structure can be set on mower, reduce, improve its induction sensitivity, can avoid using a plurality of pressure sensors pressure distribution inequality of bringing and the shortcoming of calculating inconvenience loam cake 2 rigidity requirements.
When mower was subjected to external pressure, spring 3 was compressed, and when spring 3 was compressed to as shown in Figure 2 state, two contact chips 4 contacted, line conduction, mower break-off.External pressure disappears or is reduced to limit value when following, and spring 3 begins to recover deformation, and the restoring force of spring 3 promotes loam cake 2 and moves upward, and two contact chips 4 break away from, the circuit disconnection, and mower is resumed work.
