Abstract
The invention designs an engine oil level display sensing device. The engine oil level display sensing device is directly arranged inside an automobile engine oil cylinder, achieves direct and synchronous measurement through a liquid level sensor, avoids influence on normal usage of engine oil and meanwhile has the advantages of being simple in structure and convenient to use. By changing the structure of a bottom fixing member, the liquid level sensor overcomes the problem that, when an existing sensor is applied to viscous volatile liquid, a floating ball is prone to being adhesion onto a protrusion to result in floating failure under normal conditions and the like, thereby reducing liquid waste due to the floating failure of the floating ball, improving the production efficiency and avoiding environmental pollution and body damage due to manual adhesion relieving. According to the engine oil level display sensing device, the lengths of signal wires and traction wires are strictly limited within an ideal length range obtained through repeated trials, thereby avoiding twisting and entanglement and meanwhile well meeting the test requirements of the entire engine oil level display sensing device.
Description
Technical field
The present invention relates to automobile equipment, particularly relate to a kind of engine oil level display sensing equipment.
Background technique
Machine oil, i.e. engine lubricating oil, be described as " blood " of automobile, can play the effects such as lubrication, clean, cooling, sealing, anti-attrition, antirust, corrosion protection to motor.Motor is the heart of automobile, has the metal surface of many mutual fricting movements in motor, and these component movement speed are fast, environment is poor, and operating temperature can reach 400 ° of C to 600 ° of C.Below operating mode severe like this, only have qualified lubricant oil just can reduce the wearing and tearing of engine part, increase the service life.Machine oil is made up of base oil and additive two-part.Base oil is lubrication main body of oil, and decide the fundamental property of lubricant oil, additive then can make up and improve the deficiency of base oil aspect of performance, gives the performance that some is new, is the important component part of lubricant oil.Along with the retention of automobile improves year by year, people are also increasing gradually to the frequency of utilization of machine oil.Because the replacing of machine oil directly plays an important role to the life-span of motor car engine, thus technology innovation frequency in this regard is also constantly accelerating.
All organic oil pressure indicator light on motor car engine instrument panel, whether, after engine oil pressure is lower than certain value, tutorial light is lighted, remind driver's liquid level of checking up Engine oil too low, can the height of engine oil level directly affects engine oil pressure, thus normally to have worked material impact to motor car engine.When changing machine oil, machine oil being added to suitable liquid level most important, the too high waste not only causing machine oil of liquid level, and machine oil scaling loss and energy loss can be caused; Liquid level is too low, and engine oil pressure may be caused too low.Conventional increase machine oil method is: the method taking repeatedly to check adjustment, liquid level of constantly checking up Engine oil, until liquid level reaches assigned position, whole process is loaded down with trivial details, not only loses time, and is not easy accurate control.
Summary of the invention
For solving the problem, the invention provides one and being set directly at automobile engine oil cylinder interior, carrying out direct synchro measure by liquid level sensor, and the technological scheme that can not have an impact to the normal use of machine oil in measuring phase:
A kind of engine oil level display sensing equipment, main body is Oil cylinder, also comprise liquid level sensor, signal connecting line, pulling cable and signal generator, signal generator is fixedly installed on bottom Oil cylinder, signal generator is connected with one end of signal connecting line, signal connecting line extend into Oil cylinder inner chamber through Oil cylinder shell, the signal connecting line the other end is fixedly connected with bottom liquid level sensor, above liquid level sensor, be connected with pulling cable one end, the pulling cable the other end is fixedly installed on Oil cylinder inner cavity top position.
Further, liquid level sensor structure is: the mobile jib comprising bottom firmware, top firmware, ball float, hall sensing element and hollow, hall sensing element is arranged at mobile jib inside, hall sensing element is connected with described signal connecting line, and signal connecting line extends to mobile jib outside and is connected with signal generator; Described bottom firmware and top firmware fixed cover are located at mobile jib outside, and it is outside and between bottom firmware and top firmware that ball float is movably set in mobile jib.
Further, signal connecting line length is less than Oil cylinder cavity heights 5 ~ 20mm.
Further, pulling cable length is less than Oil cylinder cavity heights 15 ~ 40mm.
Beneficial effect of the present invention is:
