Abstract
The utility model relates to a kind of glass-frame riser guide rail fastening screw trip bolt and gasket assembly, belongs to automobile glass lifter positioning component.Fastening screw trip bolt and guide rail are riveted, the bottom of this fastening screw trip bolt is vertical bar type annular knurl, middle part is screw thread, top is screw rod, the bottom interference fit of pad and fastening screw trip bolt, and this pad bore dia is greater than major diameter of thread in the middle part of fastening screw trip bolt, is less than the external diameter of vertical bar type annular knurl.Advantage is novel structure, and by guide rail fastening screw trip bolt and pad interference fit, simultaneously punching press, on aluminum alloy guide rail, realizes Y-direction location, and can not discharging any waste gas, to be conducive to employee healthy, saved electric energy simultaneously.
Description
Technical field
The utility model belongs to automobile glass lifter positioning component.
Background technique
Current, due to environmental protection and energy-conservation needs, the lightweight of automobile has become the trend of world car development.Experiment proves, if vehicle complete vehicle weight reduces by 10%, fuel efficiency can improve 6%-8%; Automobile unladen mass often reduces 100 kilograms, and fuel consumption per hundred kilometers can reduce by 0.3-0.6 liter; Vehicle weight reduces by 1%, and oil consumption can reduce by 0.7%.
The main path of automotive light weight technology is:
1. automobile primary traffic specification vehicle Continuous optimization, under the prerequisite that specification main parameter size retains, promotes complete vehicle structure intensity, reduces consumptive material consumption;
2. lightweight material is adopted.As aluminium, magnesium, pottery, plastics, glass fibre or carbon fiber composite etc.;
3. computer is adopted to carry out structural design.As adopted finite element analysis, local strengthening design etc.;
4. monocoque body is adopted, thinning vehicle body sheet thickness etc.
Wherein, current Main Auto lightweight measure mainly adopts lightweight material, and vehicle material is made contributions to fuel economy improvement mainly through the lightweight of automobile.Theory analysis and test result all show, lightweight is the effective way improving vehicle fuel economy.In order to adapt to the requirement of automotive light weight technology, some new materials arise at the historic moment and expand application area.
Glass-frame riser, as the requisite annex of car door, in order to adapt to the requirement of automotive light weight technology, alleviating glass-frame riser product weight by change part material or consumption, having become the trend of glass-frame riser development.Traditional glass track of lifter mostly is galvanized steel plain sheet, in order to alleviate product weight, brings into use density to be only the aluminum alloy guide rail of steel 1/3 gradually.
Traditional glass-frame riser steel guide rail adapts to car door lateral clearance and realizes often through two kinds of modes:
1. utilize the characteristic that Steel material specific elongation is high, stamped steel guide rail, make steel guide rail be deformed to required size, as shown in Figure 1, 2;
2. design guide rail special stand as Fig. 3, by modes such as welding, support is fixed on steel guide rail, realize car door Y-direction location, because aluminum alloy guide rail specific elongation is 16%, steel guide rail is more than 32%, aluminum alloy guide rail can not realize steel guide rail along Y-direction significantly punching press, can not by mode fixed supports on guide rail such as welding.
Summary of the invention
The utility model provides a kind of glass-frame riser guide rail fastening screw trip bolt and gasket assembly, with solve aluminum alloy guide rail self specific elongation low, not by adapting to the problem of client car door panel beating moulding compared with large deformation.
The technological scheme that the utility model is taked is: fastening screw trip bolt and guide rail are riveted, the bottom of this fastening screw trip bolt is vertical bar type annular knurl, middle part is screw thread, top is screw rod, the bottom interference fit of pad and fastening screw trip bolt, this pad bore dia is greater than major diameter of thread in the middle part of fastening screw trip bolt, is less than the external diameter of vertical bar type annular knurl;
Pad of the present utility model there is material reducing hole.
The utility model has the advantages that novel structure, by guide rail fastening screw trip bolt and pad interference fit, punching press is simultaneously on aluminum alloy guide rail, and realize Y-direction location, the material reducing hole of pad realizes loss of weight, has both realized material reducing and has saved material, can meet part strength again; Pad hole dimension is greater than screw thread external diameter, is less than the external diameter of vertical bar type annular knurl, does not destroy screw thread when pressing, and realizes the available protecting of double thread, with screw annular knurl interference fit, increases pull-off strength, improves stability.Compare in the connection procedures such as conventional steel guide rail welding and can discharge waste gas, consume a large amount of electric energy, the utility model is by pressing mode retaining washer and screw, and can not discharging any waste gas in process, to be conducive to employee healthy, saved electric energy simultaneously.

Embodiment
Fastening screw trip bolt 2 and guide rail 3 are riveted, the bottom of this fastening screw trip bolt is vertical bar type annular knurl 201, middle part is screw thread 202, top is screw rod 203, the bottom interference fit of pad 1 and fastening screw trip bolt, and this pad bore dia is greater than major diameter of thread in the middle part of fastening screw trip bolt, is less than the external diameter of vertical bar type annular knurl;
Pad of the present utility model there is material reducing hole 101.
The utility model is by guide rail fastening screw trip bolt and pad interference fit, and punching press simultaneously, on aluminum alloy guide rail, realizes Y-direction location.
Claims (2)
1. a glass-frame riser guide rail fastening screw trip bolt and gasket assembly, it is characterized in that: fastening screw trip bolt and guide rail are riveted, the bottom of this fastening screw trip bolt is vertical bar type annular knurl, middle part is screw thread, top is screw rod, the bottom interference fit of pad and fastening screw trip bolt, this pad bore dia is greater than major diameter of thread in the middle part of fastening screw trip bolt, is less than the external diameter of vertical bar type annular knurl.
