The upper hock rubbing surface 3-2-2 of the lower hock rubbing surface 3-1-2 and upper hock 3-2 of 3-1, lower hock 3-1 are tightly engaged, and compress bullet
The elastic force of spring 3-4 serves as the normal pressure of lower hock rubbing surface 3-1-2 Yu upper hock rubbing surface 3-2-2, generates stiction;
The compression travel of appropriate adjustment compressed spring 3-4 can make between lower hock rubbing surface 3-1-2 and upper hock rubbing surface 3-2-2
Stiction is greater than the resistance in vehicle dormer window opening process.The presence of stiction, it can be ensured that output power is conducted to biography
Moving gear 3-5, moving gear 3-5 are engaged with the flexible axle 4 being fixed in flexible axle conduit 5, and flexible axle 4 and the front end being located in guide rail 6 are sliding
Block 7 is fixedly connected with effective transmission, it can be achieved that output power;Front end sliding block 7 is fixedly connected with the front end of spacing bracket 10, jointly
It is translated along guide rail 6;Intermediate slider 8 in guide rail 6 is fixedly connected with spacing bracket 10, and intermediate slider 8 is immovable, only
Play the function of lifting spacing bracket 10;The end of spacing bracket 10 is connect by connecting rod 11 with limit tray 9, and tray 9 is limited
Cannot be moved in guide rail 6, connecting rod 11 around limit tray 9 rotate, in vehicle dormer window opening process drive spacing bracket 10 to
Upper forward movement drives spacing bracket 10 to move rearward in vehicle dormer window closing process;Glass supporter 12 is automobile day
Glass pane provides installation carrier, is fixedly connected by bolt with spacing bracket 10, movement in the same direction synchronous with the holding of spacing bracket 10,
The unlatching and closure of vehicle dormer window are realized with this.
In vehicle dormer window closing process, if encounter the barriers such as child, sundries, drag effect will receive, the resistance
Overload protection arrangement machinery is conducted to by mechanical parts such as glass supporter 12, spacing bracket 10, front end sliding block 7, flexible axles 4 with this
The transmission gear 3-5 of component 3.Because transmission gear 3-5 is fixedly installed on multi-diameter shaft 3-3 by spline, and upper hock 3-2 is only
It is to be inserted on multi-diameter shaft 3-3, can be moved in a certain range along multi-diameter shaft 3-3;The elastic force of compressed spring 3-4 makes tooth
The lower hock rubbing surface 3-1-2 of the upper hock rubbing surface 3-2-2 of pawl 3-2 and lower hock 3-1 tightly engages and generates stiction,
When the resistance generated by barrier is greater than the stiction, upper hock rubbing surface 3-2-2 and lower hock rubbing surface 3-1-2 are generated
Sliding;Upper hock rubbing surface 3-2-2 and lower hock rubbing surface 3-1-2 are the curved surface with certain height, therefore sliding phenomenon
Appearance will lead to the second compression again of compressed spring 3-4, and then elastic force is generated, as upper hock rubbing surface 3-2-2 and lower hock
When maximum height occurs in rubbing surface 3-1-2, compressed spring 3-4 reaches maximum value because compressing the elastic force of generation again;Compress bullet
Spring 3-4 necessarily causes to rub between upper hock rubbing surface 3-2-2 and lower hock rubbing surface 3-1-2 because compressing the elastic force of generation again
The increase of power is wiped, if be greater than the frictional force because of the resistance that barrier generates, upper hock rubbing surface 3-2-2 and hock under rubbing surface
It will appear periodic sliding between 3-1-2.Therefore, it causes the drop out of gear between hock 3-2 and lower hock 3-1 to close, leads to electricity
Machine 1 generates the cutting of power transmission approach, can effectively avoid because skylight glass continues to cause the folder to child, barrier due to closing
Wound, realizes the overload protective function of vehicle dormer window.
Below by taking specific experiment as an example, to illustrate practicability and effect of the invention.
In this embodiment, 630 mm of overall length of vehicle dormer window, 830 mm of beam overall, 530 mm of overall length of skylight glass, always
Wide 820 mm;In addition guide rail 6, front end sliding block 7, intermediate slider 8, limit tray 9 for skylight glass to be fixedly mounted, limit support
The mechanical mechanisms such as frame 10, connecting rod 11, glass 12, bracket, total weight be 12 Kg, this some mechanical mechanism vehicle dormer window open/
The frictional resistance generated in closing course is 18N;When galloping (80 km/h or more), because the resistance that windage generates is
10N.Therefore, vehicle dormer window resistance total during opened/closed is 28N.
Select cast iron for the material of lower hock 3-1,45 steel are the material of upper hock, lower hock rubbing surface 3-1-2 and upper tooth
The surface roughness of pawl rubbing surface 3-2-2 is disposed as Ra=12.5 μm, lower hock rubbing surface 3-1-2 and upper hock rubbing surface 3-
Friction factor is 0.3 between 2-2.
Vehicle dormer window resistance 28N total during opened/closed, needs lower hock rubbing surface 3-1-2 to rub with upper hock
Wiping face 3-2-2 provide stiction should be slightly larger than 28N, therefore compressed spring 3-4 provide elastic force should be 28N/0.3=
93N.It is assumed that meeting with the maximum resistance that the barriers such as child, sundries generate is 21N in vehicle dormer window closing process, i.e. resistance is super
Crossing 21N, hock rubbing surface 3-1-2 and upper hock rubbing surface 3-2-2 drop out of gear close at present, and the overload protection arrangement of vehicle dormer window is mechanical
Component 3 plays a role.At this point, lower hock rubbing surface 3-1-2 and upper hock rubbing surface 3-2-2 are because of the increased frictional force of resistance 21N
For 21N, then calculate and know that the increased elastic force of compressed spring 3-4 is 21N/0.3=70N, be arranged lower hock rubbing surface 3-1-2 with
The maximum relative surface height of upper hock rubbing surface 3-2-2 is 10 mm, then because barrier resistance leads to compressed spring 3-4 again
The range of compression is 10 mm, therefore the coefficient of elasticity of compressed spring 3-4 should be the mm=7.0 of 70N/10 N/mm.According to
Coefficient of elasticity and respective country standard, select the material of compressed spring 3-4 for carbon spring steel.Vehicle dormer window is in opened/closed
Total resistance 28N in the process, therefore the lower hock rubbing surface 3-1-2 and upper hock rubbing surface 3-2-2 stiction provided should be
The elastic force that 28N, compressed spring 3-4 are provided should be 93N, answer 7.0 N/mm in conjunction with the coefficient of elasticity of compressed spring 3-4, then automobile
Skylight is normally-open/closure when to need the compression travel of compressed spring 3-4 be that should be slightly larger than the N/mm=13.3 of 93N/7.0 mm.
