As shown in fig. 1-3, the embodiment of the present invention provides a vehicle ramp alarm triggering mechanism, which is applied to a vehicle frame 1, and comprises: roller assembly 2, sensor 5 and control unit.
The roller assembly 2 comprises a support 3 and a roller 4 connected to the support 3 in a sliding manner, the support 3 is mounted at the front end of the bottom of the frame 1, the lower end of the roller 4 is exposed out of the lower end of the support 3 and is used for contacting with a ramp, the roller 4 can slide on the support 3 along the vertical direction, the sensor 5 is arranged above the roller 4, the sensing end of the sensor 5 and the roller 4 are correspondingly arranged at intervals, specifically, a control unit is mounted in a vehicle instrument desk and is respectively connected with the sensor 5 and a display instrument 6 of a vehicle, when the roller 4 moves upwards to contact with the sensing end of the sensor 5, the control unit receives a signal of the sensor 5 and displays the signal on the display instrument 6 to remind a driver that the front part is driving into the ramp, and when the roller 4 moves upwards continuously, the sensor 5 further sends a signal to the control unit to remind the driver that the ramp is too large, so that the vehicle cannot pass through easily, and the situation that the vehicle scratches a chassis and the like is avoided.
Through setting up the gyro wheel 4 preferred contact ramp surface in the gyro wheel assembly 2 of frame 1 bottom front end, after 4 rebound of gyro wheel trigger sensor 5, sensor 5 sends the demonstration of signal to vehicle display instrument 6 department through the control unit, and then reminds the navigating mate, after reaching the certain degree, reminds here slope too big, goes forward again and damages the vehicle easily, and then avoids the easy card condition on the slope of big slope of vehicle that the chassis is low.
As shown in fig. 2 and 3, the bracket 3 includes: the bottom plate 31 is mounted at the front end of the bottom of the frame 1, the two side plates 32 are oppositely arranged at intervals and connected to the bottom of the bottom plate 31, guide grooves 33 in sliding connection with the rollers 4 are respectively formed in the two side plates 32, and the rollers 4 are mounted between the two side plates 32 through the guide grooves 33.
The rollers 4 slidably connected to the guide grooves 33 can slide up and down along the guide grooves 33 by the guide grooves 33 formed on the two side plates 32, thereby reducing impact and abrasion.
Specifically, as shown in fig. 3, a mounting plate 8 is further connected between the two side plates 32, the sensor 5 is mounted on the mounting plate 8, the sensing end of the sensor 5 faces downward and is spaced from the lower roller 4, and the mounting plate 8 not only can be used for mounting the sensor 5, but also can reinforce the structural strength between the two side plates 32.
The roller 4 comprises a shaft core 41 slidably connected in the guide groove 33 and a rim 42 rotatably connected on the shaft core 41, two ends of the shaft core 41 are slidably connected in the guide groove 33, and the rim 42 is used for contacting with the ramp and the sensing end of the sensor 5.
In this embodiment, the side plate 32 is provided with a limiting block 7 at the top of the guide groove 33, and the limiting block 7 at the top end of the guide groove 33 can prevent the sensor 5 from being damaged in a limit state.
In this embodiment, the upper limit of the roller 4 is lower than the upper limit of the sensor 5, wherein the sensor 5 may adopt a displacement sensor 5, the sensing end of the displacement sensor 5 in an initial state is spaced from the roller 4, at this time, the displacement sensor 5 is at the lower limit, after the upper limit of the sensor 5 is set to be higher than the upper limit of the roller 4, the sensor 4 can move up to the upper limit, that is, the shaft core 41 in the roller 4 moves up to the top end position of the guide groove 33, at this time, the sensor 5 also has a certain stroke and can move up, and it is possible to avoid the situation that the roller 4 continues to move up to press the sensor 5 after moving to the upper limit, and the sensor 5 is damaged.
In this embodiment, still include alarm unit, set up on the instrument desk of vehicle, alarm unit specifically can be audible-visual annunciator, alarm unit with the control unit connects, alarm unit is used for when the data that sensor 5 transmitted come reach the preset threshold value, send alarm signal, this threshold value is first threshold value this moment, when reaching first threshold value, gyro wheel 4 is for moving up to certain degree and then triggering sensor 5's first threshold value, judge at the control unit that the slope reaches this degree vehicle still not stop after, this slope probably leads to the vehicle to be unable to pass through, need in time to park, and then control alarm unit sends out the strong amazing signal of acousto-optic warning in order to remind the navigating mate to stop the vehicle, avoid the vehicle to open the uphill card.
Further, the control unit is connected with a brake system of the vehicle, and the control unit is used for sending a brake signal to the brake system when the data transmitted by the sensor 5 reaches a preset threshold value. The threshold value is a second threshold value, the second threshold value is triggered after the first threshold value, the gradient of the second threshold value is larger than that of the first threshold value, the control unit is connected with the brake system, and after the control unit judges that the gradient reaches a certain degree (namely, the second threshold value) through a signal transmitted by the sensor 5, the brake system is controlled to intervene to brake the vehicle until the vehicle is braked, so that the situation that the chassis is blocked after the vehicle is driven on a ramp because a driver does not see a display signal or an alarm signal is avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
