Abstract
An anticollision safety device with bursting discs for vehicles and boats is provided, which comprises a 1 multilevel bursting discs, 2 impact rod and 3 fixing device. The anticollision safety device can be installed in the front of the crossbeam on the vehicle chassis or the rear and side of the crossbeam when the device is used for the vehicle. When the device is installed in the front and the vehicle is collided from the facade by foreign matters, the impact rod is affected by the outside force to break every level of the bursting discs one by one; the crushing force of every level of the bursting discs is set from small to huge in advance; the breaking of the bursting discs absorbs the outside force to make the vehicle and passenger secure and collision proof and achieve the aim of protecting the vehicle and the passengers. The ''device'' can be also applied in other vehicles, boats and motional mechanical objects. The ''device'' is simple in structure, convenient in maintenance, safe, practical and reliable. With compact structure of the ''device'', the ''device'' only increases a short distance between crossbeam and bumper and will not affect the beauty of vehicles if improving the vehicle body design.
Description
Technical field: this " utility model " relates to is the anticollision safety device of communications and transportation car and boat and machinery.
Background technology: existing automobile is by the big Beam of vehicle body, and bumper/spoiler is formed when being subjected to the external force severe impact, and when exceeding its ability to bear, the vehicle frame distortion causes occupant's injures and deaths.
Have now a crashproof steelframe is housed outside bumper/spoiler, but can only protect very little impulsive contact force.
According to another media report: have the people between big Beam of vehicle body and bumper/spoiler, compression spring to be housed, can reach the purpose of partly slowing down outer impulsive force.
The utility model content: the purpose of this utility model is to improve the shortcoming of above-mentioned technology, reduces in the car and boat transportation, and the car and boat that a large amount of collisions that take place cause damage and human casualty accident, and a kind of simple, reliable, practical car and boat anticollision safety device is provided.
This " device " partly formed by three:
First is rupture disk partly.Rupture disk is selected for use has suitable intensity, but the material manufacture of enbrittling.As manufacturings such as the alloy material of hard-casting, ferrous and nonferrous metals, synthetic materiaies, outward appearance is garden cheese sheet＜accompanying drawing 4 〉, also can be designed to other shapes, a unilateral side or bilateral are pressed with shape groove in length and breadth, rupture disk is owing to select for use material difference, thickness difference to be divided into some strength grades, and rupture disk is hit crushing force through testing mensuration in advance.
Second partly for impacting rod.Be the cylindrical barred body of the many steps of different-diameter, impact end surface and multistage impact step and form (seeing accompanying drawing 3).Impact rod and use high-strength metal material, have very high intensity and toughness and when the concussion burst sheet, can not be out of shape through modifier treatment.Impact excellent rear end and be connected with front bumper, and be assemblied in the fixed mount, its effect is to be subjected to external force to do the time spent when front bumper, breaks up rupture disk one by one.
The 3rd partly is anchor fitting, and its effect is fixing rupture disk and be connected the big Beam of vehicle body, impact the device of rod, front bumper, and fixed mount sub-headend (accompanying drawing 2), rear end and a plurality of center fixed frame are formed (accompanying drawing 5).
Front end fixed mount and front bumper compress with one group of bolt column (seeing accompanying drawing 6) that is with compression spring outward, and front bumper is subjected to external force to do the time spent, and length of spring compressed, bolt column can slide in front end fixed mount hole, impact the rod slip simultaneously and smash rupture disk.
The rear end fixed mount is connected with the big Beam of vehicle body, and middle-end fixed mount, quantity are decided by rupture disk progression, use bolt between each fixed mount.
Except that the front end fixed mount, middle-end and rear end fixed mount wall are that emptying aperture is arranged, so that discharge after the rupture disk fragmentation.
Fixed mount integral body can be designed to circle or other shapes, legend for circular.
Below in conjunction with accompanying drawing this device is further described:
Accompanying drawing 1, explosion chip car and boat erosion control collision safety device site plan (is example with the automotive front end device)
Accompanying drawing 2, front end fixed mount figure
Accompanying drawing 3, impact rod figure (is example with three grades of rupture disks)
Accompanying drawing 4, rupture disk figure (is example with the single face groove)
Accompanying drawing 5, middle-end and rear end fixed mount figure
Accompanying drawing 6, " device " assembly drawing (is example, three grades of rupture disks with the left front end of automobile)
The specific embodiment:＜be example with three grades quick-fried
One, assembly technology requirement
1, the compression spring drift is a
1, entering mode of operation spring length after bolt column compresses is a
2, it is a that spring compresses back length fully
3, the compressible length of spring (usable length) a
4, i.e. a
1-a
3=a
4Spring is a
2The time, when promptly entering mode of operation, impact excellent first step and the first rupture disk spacing is b, impact excellent second step and the second rupture disk spacing is c, impacting plane rod end and the 3rd rupture disk spacing is d (accompanying drawing 6)
Require: 1. a
4＞b+c+d
②b＜c＜d
2, under the external impacts: impacting rod and bolt column can be free to slide in fixed mount.
Two, design strength principle
1, rupture disk impact failure power
＜the three group of＜the second group of first group
2, final stage rupture disk destructive force＜fixed mount deformation failure power＜vehicle frame deformation failure power
Three, " device " course of action: by shown in Figure 6.This device entered mode of operation after assembling was finished and compressed compression spring, and when automobile was subjected to frontal impact power or automobile and rushes at the place ahead obstacle, the place ahead bumper/spoiler was stressed, the compression spring compression, and bolt column slides backward.After impacting rod simultaneously and sliding backward and smash the first rupture disk group, also very big as external force, will continue to drive impact rod and smash step by step after rupture disks at different levels and destruction fixed mount.
In this process, smash one-level rupture disk and last destruction in the fixed mount whenever impacting rod, absorb partly impact energy, impulsive force is slowed down step by step, thereby reach the purpose of protection automobile itself and occupant safety.
Claims (5)
1, explosion chip car and boat erosion control collision safety device is formed by impacting excellent rupture disk and anchor fitting; it is characterized in that mechanical objects such as protected automobile; when under the situation of static and motion, being subjected to external impacts or automobile etc. and itself rushing at obstacle; impact rod in " device " and smash rupture disk step by step; pass through fixed mount; be delivered to protected mechanical object, lower impulsive force step by step, thereby reach the purpose of machineries such as protecting automobile and personal security.
2, impact rod and form, can reach the purpose of multistage concussion burst sheet by impact end surface and multistage impact step.
3, fixed mount is provided with mud hole, and rupture disk can be discharged after impacting rod to smash into fritter thus, does not influence the impact rod motion.
4, compression spring is enclosed within outside the bolt column, and " device " enters mode of operation after nut compressing.The impact rod of connection front bumper and bolt column can slide backward in anchor fitting under external force.
5, the rupture disk single or double is pressed with vertical-horizontal slot, so that rupture disk cuts into fritter impacting under the rod impact, reaches and absorbs the purpose of slowing down impulsive force and being convenient to discharge.
