Abstract
The utility model relates to an automatic alarm device for automobile tyre leakage, which comprises a pressure detection device, wherein, a pressure loss signal of a leaked tyre is changed into an electric signal through the pressure detection device; the electric signal is transported into an alarm display device in an automobile driving room to alarm and be displayed by adopting a wireless emission mode and a wireless reception mode; the pressure detection device comprises a sensing capsule which is arranged in the tyre and contains the medium, and a detection signal changeable device which is fixed on a wheel rim body. The detection signal changeable device makes a pair of electrodes which generate the detection signal switched on or switched off through the action of the medium, and changes a pressure signal into an electric detection signal.
Description
The utility model relates to the pressure detection technology, and particularly automobile tyre gas leakage decompression state-detection specifically is meant the vehicle tire leakage alarm device.
At present, tyre leakage decompression, particularly truck, because of can not in driving, in time being realized, often cause damaged tyres, scratch the road surface, even grave accident such as overturnings takes place, and a kind of simple and easy deflation warning system is arranged, be on under-carriage, to hang a steel bar, when the tire flat vehicle frame fell, this steel bar touched ground, made the contact switch action that is attached thereto, pass in the operator's compartment by lead and to report to the police, this device is not only original but also insensitive, and it is unreliable to work, and Uneven road is reported by mistake often.
The goal of the invention of the utility model is to overcome the deficiency of prior art, designs a novel gas leakage autoalarm, adopts new pressure detection method and wireless remote control technology, and advanced technology is reported to the police accurately.
The utility model is so to implement, it comprises pressure-detecting device, warning device and wireless transmission, acceptor circuit etc., its pressure-detecting device comprises a sensing capsule (1) that places the interior Sheng medium in the tire, a detection signal converting means (2) that is fixed on the wheel circle body, this converting means has a pair of electrode (10) that produces detection signal, (11), when medium in the sensing capsule (1) is extruded into this device, above-mentioned pair of electrodes disconnects, when medium is extruded passback sense capsule (1) by this device, above-mentioned pair of electrodes is connected, produce effective detection signal, this detection signal passes through wireless transmission, receiving device (20), (21) be sent to alarm display device (22), give alarm display.
This device is with pressure sensor---and sensing capsule (1) places in the tire, pickoff signals is reliable, by chromacoder pressure sensor signal is transformed to electric signal, making pressure signal be sent to warning device by wireless mode becomes possibility, and this device signal transmitting science, warning are accurately.
Embodiment below in conjunction with accompanying drawing provides elaborates to the utility model.
Accompanying drawing 1, the utility model embodiment 1 schematic diagram
Accompanying drawing 2, the utility model embodiment 2 schematic diagrams
Accompanying drawing 3, embodiment 1 its detection signal converting means constructional drawing
Accompanying drawing 4, embodiment 2 its detection signal converting means constructional drawings
Accompanying drawing 5, the utility model relate to the tire part, and it presses holding position figure
Above-mentioned accompanying drawing 1,3 is embodiment 1 embodiment figure, it has a pressure-detecting device, this detecting device is made of two parts, the one, by (between the inner tube of a tyre and the sub-tire) the sensing capsule (1) that places in the tire, the one, be fixed in the detection signal converting means (2) on the wheel circle body (19), converting means (2) has a hydraulic actuating cylinder (5), base (14) and top cover (15) are arranged, piston (9) is arranged in the cylinder, piston above (with the right side) part be hydraulic actuating cylinder epicoele (6), in a capsule (8) is arranged, it passes through to be communicated with sensing capsule (1) communicating pipe (3), piston following (with a left side) part is hydraulic actuating cylinder cavity of resorption (7), in pull back spring (13) is arranged, hydraulic actuating cylinder inwall iron chains are embedded with electrode (11), it and cylinder housing join, iron chains are embedded with electrode (10) on the piston, and it is switched to outside the cylinder body by lead (12).Alarm procedure is: when tire sufficient gas normal barometric pressure, sensing capsule (1) will be squeezed (seeing accompanying drawing 5), medium is by be extruded in the capsule in the cylinder (8) communicating pipe in the capsule, the capsule of blow-up (8) will promote piston downward (left) and move, electrode (10) and (11) are disconnected, this moment, the alarm free signal output was normal condition; Behind tire flat, sensing capsule (1) will lose external force (inner tube of a tyre extruding) effect, at this moment, in the hydraulic actuating cylinder pull back spring (13) will promote piston upwards (to the right) mobile, electrode (10) and (11) are connected, produce an on-off signal, in the present embodiment, be actually and connected feedway power supply (23), make feedway work, this feedway has a signal source circuit, and signal is launched by feedway, is received by receiving device, and be input to the alarm display device, above-mentioned sending and receiving apparatus is prior art, and the above-mentioned matter of recommending is liquid, is generally water or hydraulic pressure wet goods, above-mentioned chromacoder (2), feedway (20) and power supply (23) are installed in the box, be fixed on the wheel circle body (19), receiving device (21), alarm display device (22) is installed in the operator's compartment.Accompanying drawing 5 is that sensing capsule (1) is pressed holding position figure, between the tire outside the motor tire (16) and the inner tube of a tyre (18) sub-tire (17) is arranged, between the inner tube of a tyre and sub-tire by putting sensing capsule (1), press the wheel rim two guard ring edges of mount tyre, its section becomes approximate " U " shape structure, the sensing capsule (1) of the dress of pressing is in " U " shape depression, and when inner tube of a tyre sufficient gas, it will be squeezed, and after the gas leakage, it will lose interior tire pressure effect, be free state, make the interior medium of hydraulic actuating cylinder capsule (8) can be extruded to sensing capsule (1), during design, according to the sensitivity requirement, determine piston stroke, and then determine two capsule volumes, two capsule volumes are equal substantially, pass bundle capsule system and should make flat, when guaranteeing to leak gas decompression, capsule is not pushed by application force.
Accompanying drawing 2,4 provides the utility model another embodiment, it only is with the difference of implementing 1, remove capsule (8) in the hydraulic actuating cylinder, the hydraulic actuating cylinder epicoele is passed in and out mouth (4), is communicated with sensing capsule (1) communicating pipe (3) by medium, medium enters the interior piston that directly promotes of hydraulic actuating cylinder cavity and moves, and surplus person is identical with embodiment one.
Above-mentioned two embodiment only are wherein two kinds of embodiments of the present invention.
