Abstract
The invention provides a vehicle-mounted slope measurement apparatus, and relates to the field of safe vehicle driving, especially to slope angle understanding. In a congestion city, distances between vehicles are short, a plurality of slopes are not obvious, a plurality of drivers can not pull handbrakes, and backward slipping after starting easily cause rear collision. To reduce careless influence of unobvious slops on drivers, the present invention provides a vehicle-mounted slope measurement apparatus. The technical scheme comprises that: one end of a spring is connected with a heavy object plate, the other end is connected with a force sensor, the bottom of the heavy object plate is provided with a rolling wheel, the rolling wheel is positioned in a guiding groove, the guiding groove is positioned on a support plate, both sides of the support plate are provided with scales, and the heavy object plate is provided with a pointer for directing to the scales. According to the present invention, when a road has a certain slope, component force of the weight object plate gravity in a support plate direction stretch or compress the spring so as to drive the pointer to correspondingly move, and the component force can further be converted into an electrical signal through the force sensor. The vehicle-mounted slope measurement apparatus has the following beneficial effects that: the apparatus can be simple or complex, redundant capacity is high, and stability is high.
Description
Technical field
The present invention relates to safe driving of vehicle field, particularly to the understanding aspect of gradient angle.
Background technology
Driveway has the road in a lot of ramps, particularly mountain area; Present vehicle is numerous, and occur blocking unavoidably, mutual spacing is shorter, also has parking on ramp and starting unavoidably, during uphill starting, to slip or advancing slip after easily occurring under gravity, easily causes and knock into the back.
The city blocked up, spacing is very short and small, and some gradients are not obvious, and a lot of driver can not pull the hand brake, and slips more easily to cause and knock into the back after starting.
Summary of the invention
Affect the paralysis of driver for reducing the not obvious gradient, the present invention designs a kind of vehicle-mounted gradient measuring device.
The technical scheme that the present invention realizes goal of the invention employing is: a kind of vehicle-mounted gradient measuring device, is characterized in that: vehicle-mounted gradient measuring device is sealed in transparent boxes, and box can be dismantled; Device critical piece is weight plates, spring, back up pad and force snesor; Spring one end connects weight plates, other end attachment force sensor; Have scroll wheel bottom weight plates, scroll wheel is arranged in leading groove, and leading slot is in back up pad, and there is scale the both sides of back up pad, and weight plates has pointed scale; Vehicle-mounted gradient measuring device is fixed on vehicle, when road is uneven, when having certain gradient, the gravity of the weight plates component on back up pad direction is to spring elongation or compression, pointer is driven to do corresponding movement, this component also can change electric signal into by force snesor, is input to vehicle-mounted display device or vehicle-mounted gradient sound prompt device.
Scroll wheel bottom weight plates and have lubricating oil between leading groove, reduces friction.
Gradient sound prompt device, force snesor is by electrical signal transfer to vehicle control syetem, and vehicle control syetem calculates the angle of the gradient, and the angle of the voice report gradient.
Gradient sound prompt device is, the scale of the same side has two metal block, and two metal block are communicated with by wire, and the position of metal block can be moved, thus arranges the gradient lower limit of voice message; The metal block of both sides connects wire and loudspeaker, and loudspeaker have power supply, or loudspeaker have extraneous supply hub, and pointer is as switch, and along with the increase of the gradient, the metal block of finger slips contact both sides, thus connection circuit, the prompting ratio of slope is more dangerous.
The invention has the beneficial effects as follows: spring and scale form the device of a spring-like scale, the size of the size reflection gradient of power, device is simple and practical; During driving, can not keep a close watch on the gradient size of spring-loaded fingers instruction, can cause dispersion attention like this, therefore, voice message is as a kind of substitute scheme of redundancy always; Present vehicle has control system, and voice system is arranged in vehicle control system, is conducive to the size accurately pointing out the gradient, but this systematic comparison is complicated, if not first wife, may be difficult to again implant, therefore, simple voice reporting system is also a kind of reasonable selection; Simple voice reporting system, its sensitivity is determined by the position of slide block, and it is slip after the section of upward slope slope that common people compare what fear, and therefore sensitivity can asymmetric design, and namely slide block can move, and now pointer doubles as switch; Device can simply, can be complicated, amount of redundancy is large, improves its stability.

Embodiment
Vehicle-mounted gradient measuring device is sealed in transparent boxes, and box can be dismantled, and the object of sealing is the corrosion that assurance device is subject to dust and steam less; Device critical piece is weight plates 5, spring 6 and force snesor 7, and scroll wheel is arranged at the bottom of weight plates, and scroll wheel is arranged in leading groove 2, and leading slot is in back up pad 1, and there is scale 3 both sides of back up pad 1, and weight plates 5 has pointer 4 to point to scale.
Vehicle-mounted gradient measuring device is fixed on vehicle, when road is uneven, when having certain gradient, the gravity of weight plates 5 component on back up pad direction is to spring elongation or compression, pointer 4 is driven to do corresponding movement, this component also can change electric signal into by force snesor 7, is input to vehicle-mounted display device or vehicle-mounted gradient sound prompt device.
Because the component F of gravity and gravity G is trigonometric function, become the relation of F=Gcos (a) with the angle a of the gradient, therefore scale is nonlinear relationship.
Gradient sound prompt device, force snesor 7 is by electrical signal transfer to vehicle control syetem, and vehicle control syetem calculates the angle of the gradient, and the angle of the voice report gradient.
Gradient sound prompt device can simplify, and the scale of the same side has two metal block, 8, two metal block to be communicated with by wire, and the position of metal block can be moved, thus arranges the gradient lower limit of voice message; The metal block of both sides connects wire and loudspeaker 9, and loudspeaker have power supply, or loudspeaker have extraneous supply hub, and pointer 4 is as switch, and along with the increase of the gradient, the metal block of finger slips contact both sides, thus connection circuit, the prompting ratio of slope is more dangerous.
