Abstract
The utility model provides a kind of road 3D data acquisition car kilometer sensor flexible jointing-rod, it mainly comprises flexible connecting member and expansion link, described expansion link is fixed on the lappet of vehicular sideview, described flexible connecting member one end is connected with expansion link by retaining element, the other end is connected with sensor outer housing, when wheel moves up and down because pavement roughness produces, flexible connecting member drives expansion link to move up and down together with wheel, to guarantee that the sensing dish of sensor internal can High Rotation Speed, and sensor outer housing is in relative static conditions.Described flexible connecting member selection, for having certain plastic engineering ABS plastic, nylon or Polyurethane sheet material, can reduce the absorption of the unfavorable resonance power producing when sensor outer housing is moved, and avoids the damage to sensor.
Description
Technical field
The utility model relates to a kind of car-mounted device, particularly relates to a kind of connecting link.
Background technology
Conventionally the speed mileage meter error of common vehicle self instrument is larger, and error rate is about every 1000 meter 5%.Speed per hour is during lower than 15km/h, and error rate can increase by 1%～3%.When speed is during lower than 5km/h, error cannot be differentiated.Because common most of vehicle is to adopt magneto-electric odometer sensor, its sensitivity is bad when low speed driving; Resolution neither be very high, is generally 45 °/r～90 °/r.So, this type of signal accuracy, when high precision movement measurement data acquisition, cannot be applied as basis signal.Inventor has studied a kind of odometer sensor being fixedly installed on hub for vehicle wheel, this kind of sensor accuracy is very high, but in order to make this normal operation of sensor, need to will on sensor, with the shell of Laser emission and receiving trap, fix, with wheel, do not rotate, common connecting link easily fractures when road jolts.
Utility model content
In view of above problem, fundamental purpose of the present utility model is to provide a kind of road 3D data acquisition car kilometer sensor flexible jointing-rod, and this connecting link is simple in structure, can effectively solve the problem that fractures of jolting and causing because of road.
In order to reach above object, this kind of road 3D data acquisition car kilometer sensor flexible jointing-rod that the utility model provides, it mainly comprises flexible connecting member and expansion link, described expansion link is fixed on the lappet of vehicular sideview, described flexible connecting member one end is connected with expansion link by retaining element, the other end is connected with sensor outer housing, when wheel moves up and down because pavement roughness produces, flexible connecting member drives expansion link to move up and down together with wheel, to guarantee that the sensing dish of sensor internal can High Rotation Speed, and sensor outer housing is in relative static conditions.
Further, described flexible connecting member selection, for having certain plastic engineering ABS plastic, nylon or Polyurethane sheet material, can reduce the absorption of the unfavorable resonance power producing when sensor outer housing is moved, and avoids the damage to sensor.
The not enough 1mm of lappet thickness of scale of general vehicle, conventionally in 0.6-0.9mm left and right, if while adopting rigid connection fixation of sensor shell, as bulb piston, when not avoiding colliding with barrier, not only sensor outer housing can damage, also likely fragile lappet iron sheet own is caused to larger damage, therefore the utility model adopts flexible connection mode to fix sensor outer housing, can when collision, absorb a part of damage effect power, to reduce the damage larger to vehicle body.
Accompanying drawing explanation
Fig. 1 is 3D data acquisition car kilometer sensor flexible jointing-rod structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the technical solution of the utility model is further illustrated, but does not do the restriction to it:
A kind of road 3D data acquisition car kilometer sensor flexible jointing-rod that the utility model provides, as shown in Figure 1, it mainly comprises expansion link 10 and flexible connecting member 20, described expansion link 10 is fixed on the lappet of vehicular sideview, described flexible connecting member 20 one end are connected with expansion link 10 by retaining element, the other end is connected with sensor outer housing 30 by retaining element, when wheel moves up and down because pavement roughness produces, flexible connecting member 20 drives expansion link 10 to move up and down together with wheel, to guarantee that the sensing dish of sensor internal can High Rotation Speed, and sensor outer housing 30 is in relative static conditions.
Further, described flexible connecting member 20 selections are for having certain plastic engineering ABS plastic, nylon or Polyurethane sheet material, and the absorption of the unfavorable resonance power producing in the time of can reducing sensor outer housing 30 motion, avoids the damage to sensor.
The not enough 1mm of lappet thickness of scale of general vehicle, conventionally in 0.6-0.9mm left and right, if while adopting rigid connection fixation of sensor shell, as bulb piston, when not avoiding colliding with barrier, not only sensor outer housing can damage, also likely fragile lappet iron sheet own is caused to larger damage, therefore the utility model adopts flexible connection mode to fix sensor outer housing, can when collision, absorb a part of damage effect power, to reduce the damage larger to vehicle body.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model instructions and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
