Abstract
The utility model relates to a bulkhead fixing device of on-vehicle wall-hanging type display equipment. The bulkhead fixing device comprises a bulkhead fixing bracket and a first switching frame. The bulkhead fixing bracket is used for fixedly connecting with a bulkhead, the first switching frame is used for installing the display equipment, and the first switching frame is connected with the bulkhead fixing bracket by a vibration isolator. The bulkhead fixing bracket comprises a bulkhead fixing plate and a second switching frame which is fixedly arranged on the bulkhead fixing plate. The first switching frame is connected on the second switching frame by the vibration isolator. The vibration isolator is a steel wire rope vibration isolator. The display equipment is connected with the on-vehicle bulkhead by the switching frames and the vibration isolator; in the vibration environment of on-vehicle transportation, external excitation is first transmitted on the bulkhead fixing bracket by the bulkhead, then weakened by the vibration isolator, and finally transmitted on the display equipment by the second switching frame; therefore, the damage to the display equipment by the external excitation and impact excitation is reduced, and the on-vehicle safety performance of the display equipment is improved.
Description
Technical field
The utility model relates to a kind of vehicle-mounted wall-hanging display equipment bulkhead anchor fitting.
Background technology
In some special vehiclees, often need utilize large-screen display equipment that real-time imaging is provided since the display equipment volume greatly, easily cracked, become a difficult problem in installing so how to control mechanical vibration in the transportation.
At present, domestic the most frequently used be " photo frame type " installation method: be about to wrap around the display equipment and be fixed on the attachment (as carrying a car bulkhead); The method that adopts support to install is also arranged, directly use the reservation screw hole at the display equipment back side to be fixed.This class mounting means does not all adopt vibration isolation measure, and the vibrational excitation meeting is delivered in the display equipment vibration transmissibility η by 100% when vehicle-mounted transportation
v≈ 1, causes the display equipment damage under abominable transportation environment easily.
The utility model content
The purpose of this utility model provides a kind of vehicle-mounted wall-hanging display equipment bulkhead anchor fitting, to solve the frangible display equipment problem that wall hanging is installed under vehicle-mounted state.
For achieving the above object, the utility model adopts following technical scheme: vehicle-mounted wall-hanging display equipment bulkhead anchor fitting, this device comprises the first switching framework that is used for the affixed bulkhead fixed mount of bulkhead and is used to install display equipment, and the first switching framework links to each other with the bulkhead fixed mount by vibration isolator.
Described bulkhead fixed mount comprises the bulkhead adapter plate and is installed in the switching of second on bulkhead adapter plate framework that the first switching framework is connected on the second switching framework by vibration isolator.
Described vibration isolator is a steel-wire isolator.
Described first, second switching framework is the identical class of contour structure eight rib body disc shelf structures, and the periphery at class eight rib body disc frame two ends all has the installation edge of turning up; The second switching framework, four steel-wire isolators that are connected in four lopsided installations up and down along last correspondence, the first switching framework links to each other with each steel-wire isolator by cooresponding installations edge.
The utility model adopts the principle of passive insulation, utilize the switching framework display equipment to be connected effectively with a year car bulkhead with vibration isolator, under the vibration environment of vehicle-mounted transportation, external excitation at first is delivered on the bulkhead fixed mount by bulkhead, by the vibration isolator decay, be delivered on the display equipment through the second switching framework more then.This device mounting structure is reliable, has reduced external vibration and shock-excitation to the damage that display equipment caused, and has improved the vehicle-borne safety performance of display equipment.In addition, the utility model can be changed for the switching framework according to the requirement of different display equipments, makes it have more suitability; Steel-wire isolator also can be adjusted by different display equipments simultaneously, selects for use conveniently, and therefore, this technical scheme has very strong extendability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of bulkhead fixed mount in the utility model.
The specific embodiment
Fig. 1, shown in Figure 2 be the vehicle-mounted wall-hanging display equipment bulkhead anchor fitting that splits in turn by the installation site, this device comprises the first switching framework 2 that is used for the affixed bulkhead fixed mount of bulkhead and is used to install display equipment, the bulkhead fixed mount comprises bulkhead adapter plate 6 and is installed in second on bulkhead adapter plate switching framework, 5, the first switching frameworks 2 by welding and is connected on the second switching framework 5 by steel-wire isolator 3.
Above-mentioned first, second switching framework is the identical class of contour structure eight rib body disc shelf structures, and the periphery at class eight rib body disc frame two ends all has the installation edge of turning up; The second switching framework 5, four steel-wire isolators, 3, the first switching frameworks 2 that are connected in four lopsided installations up and down along last correspondence link to each other with each steel-wire isolator 3 by cooresponding installations edge.
The second switching framework 5 and bulkhead adapter plate 6 weld togethers of bulkhead fixed mount, the bulkhead adapter plate is fixed on by the screw combination and carries on the car bulkhead, the second switching framework 5 is by the screw steel-wire isolator 3 that is connected, first switching framework 2 one ends are by the screw steel-wire isolator 3 that is connected, and the other end is by the screw display equipment 1 that is connected.
In the present embodiment, four steel-wire isolators 3 are selected GGT 48-64 type for use, press radial force and use, and vertical direction is arranged in " two splayed "; Its performance perameter is: load-carrying capacity 8kg, quiet mean rigidity 22N/mm, maximum dynamic deformation 37mm, maximum impact force 1.4KN can hold 14.2J, and load weight is 15kg, adjust back four vibration isolators combination and can satisfy operating needs, and bigger safety factor can be provided.
First, second switching framework is a class eight rib body structures, plays switching, adaptive.Switching framework one end connects display equipment or bulkhead adapter plate, and the other end connects four steel-wire isolators, has adaption function, and its profile is simple and direct firm, easy to use; The switching framework can also be according to the variation of steel-wire isolator and display equipment and suitably adjustment has good adjustable.
The utility model takes the passive insulation measure to realize vibration transmissibility η
v≤ 1, its physical model is the cantilever beam combination.Consider vehicle-borne three-dimensional impact condition, reasonably combined vibration isolator combination drops to nadir with the harm of vibrating and impact, to reach design goal.
