Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail embodiment:
As shown in Figure 1, device for measuring barrier when the present invention is a kind of reversing automobile, comprise probe 2, described probe 2 is installed on the rear bumper 1, probe 2 is set to one or more, described probe 2 is set on rear bumper 1 movably structure, and described probe 2 is connected with radar for backing car module 5, and radar for backing car module 5 is connected with distance display unit 8.
Described radar for backing car module 5 is connected with gearshift 7, and described probe 2 is set on bumper 1 from rear bumper left side 9 structures that move back and forth to rear bumper right side 10.
On the described rear bumper 1 recessed guide groove 3 is set, motor 4 is installed in one end of described guide groove 3, the other end is provided with post bolt 11, suit travelling belt 6 on described motor 4 and the post bolt 11, described probe 2 is fixedlyed connected with the one side of travelling belt 6 inboards, like this, 2 are fixed on the travelling belt because pop one's head in, therefore, probe 2 is when travelling belt 6 to-and-fro movements, can be with its to-and-fro movement, this has just realized popping one's head in and 29 has moved to the function on rear bumper right side 10 from rear bumper left side on rear bumper 1, thus can accurately capture the position of barrier 12 and accurately calculate barrier 12 and rear bumper 1 between air line distance, by the measurement of air line distance accurately, be convenient to the driver and in reversing process, judge spacing accurately, thereby avoid collision to take place.
Described guide groove 3 is set to horizontally disposed strip groove structure on rear bumper 1, described motor 4 is set to just change the structure that counter-rotating hockets.
A motor 4 is respectively installed at the both ends of described guide groove 3, and travelling belt 6 is sleeved on two motors 4.
The cross section of described guide groove 3 inner chambers is set to " G " font structure, and described probe 2 cross sections are set to " scholar " font structure, and described probe 2 is inlaid in " G " font structure of guide groove 3 inner chambers.
The optimum number of described probe 2 is for being provided with 3, and at this moment, cost is minimum.
Described distance display unit 8 is a display screen, and display screen is arranged on the instrument panel of pilothouse.
The present invention is for avoiding the limitation of reversing probe 2 of the prior art, 2 be set to transportable structure by popping one's head in, thereby make probe 2 can accurately judge the position of car and obstruction 12, thereby make the driver in narrow space, operate automobile smoothly, avoid the generation of accidents such as colliding.
The present invention is the move backward function of spacing of the measurement that utilizes radar for backing car module 5 and probe 2 to have after being connected, utilize the comprehensive measurement of probe 2, accurately judge the distance of car and obstruction 12, distance on the distance display unit 8 of while in pilothouse between display automobile rear bumper 1 and the barrier 12, thereby be convenient to the driver according to concrete distance, the reversing of operation vehicle.
Backing distance display unit 8 range of a signal are owing to the concrete air line distance that can accurately judge between probe 2 and the barrier 12, so the distance display precision that is shown on the distance display unit 8 will improve greatly.
For intelligent requirements, the reversing probe all is installed on most of cars, in view of excessive waste and cost problem, the reversing probe 2 of patent of the present invention is installed 3, by 3 probes 2 moving on rear bumper 1, reach the purpose of comprehensive measurement car and obstruction 12, thereby can accurately calculate object distance behind the car.
As shown in Figure 2, probe 2 is movably arranged in the guide groove 3 of rear bumper 1 among the present invention, and motor 4 drives driving-belt 6, thereby makes that each probe 2 in the guide groove 3 can be the function that moves in the present guide groove 3.
Described motor 4 respectively is provided with one at guide groove 3 both ends, motor 4 is set to just change the structure that counter-rotating hockets, motion by motor 4, driving travelling belt 6 rotates in guide groove 3, thereby drive probe 2 to-and-fro movements in guide groove 3, like this, the distance of feasible probe 2 detecting obstacles thing 12 in continuous motion process.
The metering system of the distance between car and obstruction of existing measurement mechanism, be to realize measuring distance by two probes that are fixed on the rear bumper both sides, but because this structure can not perceive the air line distance c of barrier 12, and can't measure barrier and the probe between angle a and b (being angle a and b shown in Figure 2), be the basis by distance b like this, the distance that adopts the triangulation calculation method to calculate has certain error with actual range.
And measurement mechanism of the present invention, because probe 2 motion constantly in guide groove 3 so just makes probe 2 can accurately measure the air line distance c of barrier 12, its measuring distance is also more accurate.
The motion of travelling belt 6 relies on the motor 4 at travelling belt 6 two to drive its work, the rotation that finally reaches motor 4 drives the function of probe 2 move left and right, as shown in Figure 2, probe 1 can move to the position that is in air line distance with barrier 12, go the distance between measuring sonde 2 and the barrier 12, so just make that the whole rear position of whole rear bumper 1 is comprehensive all in the line measurement scope of probe 2.
Control system annexation synoptic diagram of the present invention as shown in Figure 3, radar for backing car module 5 receives the astern signal of gearshift 7, at this moment, just notify radar for backing car module 5 and motor 4 to work simultaneously, radar for backing car module 5 passes to the signal of radar module 5 according to probe 2, relatively which probe 2 is delivered to the distance value minimum of module 5, just the distance value with minimum sends distance display unit 8 to, by being presented at the concrete numerical value on the distance display unit 8, how the prompting driver carries out next step operation.
Fig. 4 is the sectional structure synoptic diagram of the A-A of Fig. 1, and what Fig. 4 showed is the position of probe 2 in guide groove 3, and this structure of supporting makes the position of probe 2 be limited in the structure of guide groove 3 inner chambers.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously the concrete realization of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or design of the present invention and technical scheme are directly applied to other occasions without improving, all in protection scope of the present invention.
