Abstract
The invention relates to a fixed connection structure of an air conditioner bolt of a passenger car. The technical scheme is as follows: the fixed connection structure of the air conditioner bolt of the passenger car comprises an air conditioner fixed channel steel fixedly connected with the top framework of a passenger car body; a high-intensity connection bolt sequentially passes through an assembling hole on the air conditioner fixed channel steel, an assembling hole of a top skin of the passenger car, a rubber washer, an air conditioner base of the passenger car and a large washer and is fixed through a clamp nut; a bolt head of the high-intensity connection bolt is located in a trough of the bolt fixed channel steel; and the groove opening of the bolt fixed channel steel faces upward and is welded and fixed on the bottom face of the groove of the air conditioner fixed channel steel. The fixed connection structure provided by the invention has the advantages of reliable connection quality, low production cost, easiness for assembly and strong practicability, and can be used for completely avoiding the welding of the head of air conditioner bolts, greatly improving the operational safety of the passenger car, avoiding traffic accidents caused by the problem and improving the social benefits and economic benefits.
Description
Technical field
The present invention is a kind of coach air conditioner bolt fixed connection structure.
Background technique
At present, along with the raising of scientific and technological level, the technical equipment ability of passenger vehicle constantly promotes, meet the demand that passenger is more and more higher, as the human oriented design in car, identify complete, soft interior trim and packaging, aesthetic appearance is good, and the inside and outside noise of car is little, and in car, sealing will be got well, air cleaner, free from dust, vehicle interior temperature is suitable, and driving stability, without jolting sense.Wherein, suitable temperature and clean air quality have to be suitable for and alleviate passenger's sense of fatigue of riding in passenger car, have the life and health that is suitable for passenger, meanwhile, improve the travelling comfort that passenger takes advantage of, and mood is easily loosened.
Above-mentioned is to realize by the work of aircondition to the requirement of air quality and temperature on passenger vehicle, first, requires air-conditioning normally to work, and meanwhile, air-conditioning can carry out temperature adjusting and air quality adjusting according to passenger's requirement.Wherein, the mode that is fixedly connected with of air-conditioning is particularly important, on the one hand air-conditioning is connected on passenger-car roof skeleton, meanwhile, its linkage structure can ensure, in air-conditioning using process afterwards, to withstand complicated distortion power and punching shear, fully ensure that linkage structure does not rupture, do not snap, do not lose efficacy.
General passenger vehicle manufacturer adopts the bolt of M12 that air-conditioning is fastened on roof frame, and bolt arranges upward, and bolt head is welded on the built-in board of roof frame.Due to the particularity of welding, more concentrated heat makes bolt head produce Quenching Treatment, and the metal inside tissue of bolt head changes, and material becomes fragile, in passenger vehicle running, bring to a halt or take a sudden turn once occurring, be easy to occur herein fracture, in the time that bolt fracture quantity exceedes 3, air-conditioning will wholely fall down from passenger vehicle top, gently air-conditioning comes off and scraps, heavy will cause traffic accident, causes larger loss.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of quality of connection comparatively reliable, manufacturing cost is low, easily installation is assembled, and the technological scheme of the coach air conditioner bolt fixed connection structure that exploitativeness is strong adopts the technical program can thoroughly avoid the welding of air-conditioning bolt head, when passenger vehicle operation, Security improves greatly, avoided passenger vehicle to go wrong herein completely, thereby all kinds of traffic accidents that cause improve Social benefit and economic benefit.
The present invention realizes by following technical measures: a kind of coach air conditioner bolt fixed connection structure, comprise the fixing channel-section steel of the air-conditioning being fixedly connected with the passenger-car roof skeleton of bus body, there is high strength connecting bolt successively through the pilot hole on the fixing channel-section steel of air-conditioning, the pilot hole of passenger-car roof-skin, rubber washer, coach air conditioner base, large washer is also fixed by tightening nut, the spiral shell head of described high strength connecting bolt is positioned at the groove of the fixing channel-section steel of described bolt and gives high strength connecting bolt axially support power by the fixing channel-section steel of described bolt, the spiral shell head of described high strength connecting bolt does not weld, described bolt fixed groove steel tank mouth upwards and be weldingly fixed on the groove inner bottom surface of the fixing channel-section steel of described air-conditioning.
Further improvement of the present invention also has, and on above-mentioned high strength connecting bolt, lock nut is also installed.
The fixing channel-section steel of above-mentioned air-conditioning is fixedly welded on passenger-car roof skeleton.
Beneficial effect of the present invention is:
Air-conditioning bolt connection quality in the present invention is comparatively reliable, thoroughly avoid the welding of bolt head, when passenger vehicle operation, Security improves greatly, avoid passenger vehicle to go wrong herein completely, thereby all kinds of traffic accidents that cause, improved Social benefit and economic benefit, and its manufacturing cost are low, easily installation is assembled, and exploitativeness is strong.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, this programme is set forth.
A kind of coach air conditioner bolt fixed connection structure, comprise the fixing channel-section steel 207 of the fixing air-conditioning welding of passenger-car roof skeleton 202 with bus body 200, have high strength connecting bolt 208 successively through the pilot hole of the pilot hole on the fixing channel-section steel 207 of air-conditioning, passenger-car roof-skin 201, rubber washer 206, coach air conditioner base 102, large washer 205 and fixing by tightening nut 204 after lock nut 203 is also installed, play the object of mechanical locking Drop-proof.The spiral shell head of described high strength connecting bolt 208 is positioned at the groove of the fixing channel-section steel 209 of described bolt, described bolt is fixed channel-section steel 209 notches upwards and is weldingly fixed on the groove inner bottom surface of the fixing channel-section steel 207 of described air-conditioning, therefore, the fixing channel-section steel of bolt can not come off and move; High strength connecting bolt makes to keep gap and elasticity to be connected coach air conditioner base 102 and passenger-car roof-skin 201 through rubber washer.The present invention can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present invention, also should belong to protection scope of the present invention.
