Description
Technical field
The utility model relates to a kind of isolation mounting, particularly a kind of decoupling isolation mounting that is used for electronic equipment.
Background technology
At present, common isolation mounting is made up of vibration isolation carriage and vibration isolator.The vibration isolation carriage comprises device carrier and external bracket, and device carrier is connected with external bracket by vibration isolator.Electronic equipment is installed on the device carrier, when vibrational excitation appearred in external environment, the energy of vibrational excitation was delivered to vibration isolator by external bracket, under the attenuation of vibration isolator, the vibrational energy that passes to electronic equipment is effectively reduced, thereby reaches the purpose of vibration isolation.But the vibration isolating effect and the direction of vibration isolator in the market are closely related, and stiffness differences is bigger on the vibration isolator all directions.When design of electronic devices vibration isolation carriage, the barycenter of electronic equipment can depart from the vibration isolation geometric center, will produce bigger coupled vibrations during vibration, and this will produce bigger destruction to electronic equipment.
The utility model content
The purpose of this utility model is to provide a kind of decoupling isolation mounting that is used for electronic equipment, solves the problem of existing isolation mounting coupled vibrations.
A kind of decoupling isolation mounting that is used for electronic equipment comprises external bracket, device carrier, back vibration isolator and bottom vibration isolator, also comprises fixed block, saddle, sliding bar, slip cap and end cap.Slip cap presses fit into fixed block, and two ends compress by end cap, and the end cap screw is on fixed block; Sliding bar passes slip cap and is fixed by saddle, and slip cap and sliding bar can slide up and down, and the saddle screw is in the upper end of device carrier, and the focus point on setting height(from bottom) and the device height direction mates.Two back vibration isolator screw are between fixed block and external bracket, and two bottom vibration isolators place equipment barycenter bilateral symmetry to distribute, and screw is between device carrier and external bracket.
When vibration occurring in vertical direction, produce displacement between device carrier and the external bracket in vertical direction, device carrier drives saddle and sliding bar moves together, and slip cap can slide on the sliding bar surface, make slip cap, fixed block, back vibration isolator and external bracket not move with device carrier, eliminated of the influence of back vibration isolator to device carrier, guarantee to realize the vibration isolation effect by the bottom vibration isolator fully, the equipment barycenter overlaps with vibration isolator center, bottom because this side up, can avoid producing the coupled vibrations of vertical direction.When horizontal vibration occurred, the direction of displacement of device carrier was vertical with sliding bar, and slip cap and sliding bar can not produce relative displacement, thereby displacement is affacted on the vibration isolator of back, and back vibration isolator and bottom vibration isolator play the vibration isolation effect simultaneously.Back vibration isolator setting height(from bottom) and short transverse focus point are complementary during installation, with avoid the generation level to coupling.
This device can effectively be avoided the vibration coupling of all directions, improved the anti-vibrating and impact effect of electronic equipment, and simple structural design is convenient to assembling, has satisfied the vibration index request of the vehicle-mounted ruggedized electronics equipment of vibration index request, especially crawler type of vehicle electronic device.

Embodiment
A kind of decoupling isolation mounting that is used for electronic equipment comprises external bracket 1, device carrier 2, back vibration isolator 3 and bottom vibration isolator 4, also comprises fixed block 5, saddle 6, sliding bar 7, slip cap 8 and end cap 9.Slip cap 8 presses fit into fixed block 5, and two ends compress by end cap 9, and end cap 9 screw are on fixed block 5; Sliding bar 7 passes slip cap 8 and is fixed by saddle 6, and slip cap 8 can slide up and down with sliding bar 7, and saddle 6 screw are in the upper end of device carrier 2, and the focus point on setting height(from bottom) and the device height direction mates.Two back vibration isolator 3 screw are between fixed block 5 and external bracket 1, and two bottom vibration isolators 4 place equipment barycenter bilateral symmetry to distribute, and screw is between device carrier 2 and external bracket 1.Wherein fixed block 5 and saddle 6 adopt duralumin, hard alumin ium alloy, to guarantee enough intensity; Slip cap 8 adopts nylon material, reserves 0.01mm～0.02mm magnitude of interference and is pressed into fixed block 5, and nylon material and stainless coefficient of friction are lower, avoids because frictional damping influences the vibration isolating effect of vibration isolation carriage; Sliding bar 7 adopts stainless steel material, and the fit tolerance between slip cap 8 and the sliding bar 7 is 0.01mm～0.02mm matched in clearance; End cap 9 is pushed down slip cap 8 and is avoided it to produce axial endplay.
When vibration occurring in vertical direction, produce displacement in vertical direction between device carrier 2 and the external bracket 1, device carrier 2 drives saddle 6 and sliding bar 7 moves together, and slip cap 8 can slide on sliding bar 7 surfaces, make slip cap 8, fixed block 5, back vibration isolator 3 and external bracket 1 not with device carrier 2 motions, eliminated the influence of 3 pairs of device carriers 2 of back vibration isolator, guarantee to realize the vibration isolation effect by bottom vibration isolator 4 fully, the equipment barycenter overlaps with bottom vibration isolator 4 centers because this side up, can avoid producing the coupled vibrations of vertical direction.When horizontal vibration occurred, the direction of displacement of device carrier 2 was vertical with sliding bar 7, and slip cap 8 can not produce relative displacement with sliding bar 7, thereby displacement is affacted on the back vibration isolator 3, and back vibration isolator 3 plays the vibration isolation effect simultaneously with bottom vibration isolator 4.Back vibration isolator 3 setting height(from bottom)s and short transverse focus point are complementary during installation, with avoid the generation level to coupling.
