Abstract
The utility model discloses a vibration damping crate for a vehicle hard disk video recorder. The crate consists of an upper cover, a base seat, a revolving door, an anti theft lock, a steel wire rope shock absorber, a fan, a transition bracket, a fastening screw and a nylon button type choke plug; the steel wire rope shock absorber is adopted as a whole machine vibration damping element of the vehicle hard disk video recorder; through optimizing the technical parameter and the installation manner of the steel wire rope shock absorber, the influences of vibrating and impacting to the hard disk in the driving process are obviously reduced, and the operation stability and the service life of the machine are improved; compared with the prior vehicle hard disk video recorder which takes rubber and spring plates as the vibration damping element, the machine after the utility model is installed has lower inherent frequency and more outstanding performances of vibration isolation and scour prevention, and the vibration damping element has the advantages of uneasy aging, wide range of temperature, stable performance, etc., thereby the utility model has good practical popularize value.
Description
Technical field
The utility model relates to a kind of vibration absorber of vehicle electronic device, especially the vibration damping cabinet of vehicle-mounted hard disks video recorder.
Background technology
Hard disk is to vibration and impacts extremely responsive data storage device.At present, known vehicle-mounted hard disks video recorder complete machine vibration absorber is a damping element with rubber or shell fragment, and this class damping element has reduced vibration to a certain extent, impacted the influence to machine, but thoroughly is resolved far away.There are problems such as easily aging, easy to wear in rubber absorber, the shell fragment damping element is the natural frequency height then, vibration isolation ability, these limitation become a big obstacle of vehicle-mounted hard disks video recorder widespread use, also are the gordian techniquies that each vehicle-mounted hard disks video recorder manufacturer falls over each other to break through.
The utility model content
For overcoming existing vehicle-mounted hard disks video recorder vibration isolation erosion control poor performance, deficiencies such as mission life is short, the utility model has adopted wire rope damper as the core damping element, in conjunction with DVR characteristics optimal design a kind of vehicle-mounted hard disks video recorder vibration damping cabinet, the vibration isolation erosion control performance and the mission life of vehicle-mounted hard disks video recorder can be obviously improved through real vehicle this vibration damping of evidence cabinet that runs away, the performance requirement of daily passenger stock can be satisfied basically the vehicle-mounted hard disks video recorder.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of vehicle-mounted hard disks video recorder vibration damping cabinet, and it mainly is made up of loam cake, base, revolving door, theftproof lock, wire rope damper, fan, transition bracket, trip bolt and nylon hole plug; Described wire rope damper one end is connected with transition bracket, and the other end is connected with the supporting construction of base.
Further, described wire rope damper is 4, and 45 ° of side direction are installed; Have the circumference array air vent on the described base rear panel, and powerful fan is installed; Described base both sides panel and revolving door top have waist shape louvre; Described chassis cover and base are connected by trip and screw; The supporting construction of described base is integrally formed, and there is the bending ear of strengthening support strength at two ends; Described base has bottom surface entrance hole and side entrance hole.
The beneficial effects of the utility model are, the utility model has obviously improved the vibration isolation erosion control performance and the stability of vehicle-mounted hard disks video recorder, have prolonged machine serviceable life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified;
Fig. 1 is the side view of the utility model vehicle-mounted hard disks video recorder vibration damping cabinet;
Fig. 2 is the exploded view of the utility model vehicle-mounted hard disks video recorder vibration damping cabinet;
Fig. 3 is the upward view of the utility model vehicle-mounted hard disks video recorder.
Embodiment
The utility model mainly is made up of loam cake 1, base 5, revolving door 9, theftproof lock 11, wire rope damper 4, fan 10, transition bracket 3, trip bolt 14, nylon hole plug 6.For the solution vibration, shock effect is serious and the too short problem of mission life, we have selected for use, and vibration isolation erosion control performance is outstanding, stable, mission life is not subjected to ectocine novel damping element---wire rope damper substantially, vibration damper one end is connected with vehicle-mounted hard disks video recorder shell transition bracket, and the other end is connected with vibration damping chassis base supporting construction; For solving the machine heat dissipation problem, on the chassis base rear panel, offer the air vent of circular array and powerful fan is installed, the upper surface of video recorder is the main radiating surface of hard disk, two sides are respectively the main radiating surfaces of power module and GPS module, therefore offered waist shape louvre at the top of revolving door and the relevant position of base both sides panel, cabinet inside forms good heat dissipation wind channel; For increasing the support strength of cabinet, the vibration damper supporting construction of base adopts integrated design, and has increased the bending ear in both sides; For conveniently using and keeping in repair, chassis cover and base adopt trip and screw to be connected; For adapting to the demand of multiple inlet wire mode, on chassis base, offered bottom surface entrance hole and side and carried out the hole.
Particularly, in Fig. 2, wire rope damper 4 one ends are connected with the transition bracket 3 of DVR 2, the other end is connected with supporting construction 16 on the chassis base 5, wherein transition bracket 3 adopts trip bolt to be connected with DVR 2 shells, DVR 2 just is suspended in the vibration damping chassis base 5 like this, utilizes the vibration isolation erosion control characteristic of the wire rope damper 4 of 4 45 ° of side direction installations to reduce extraneous vibration well, impacts the influence to DVR.For solving heat dissipation problem, on chassis base 5 rear panels, offered circular array air vent 20 and powerful fan 10 has been installed, be to increase DVR upper surface and two sides heat-sinking capability, offered waist shape louvre 12,8,13 in the relevant position of the both sides panel of the top of cabinet revolving door 9 and base 5.For increasing the support strength of cabinet, the vibration damper supporting construction 16 of base 5 adopts integrated design, and has increased the bending ear in both sides; For conveniently using and keeping in repair, chassis cover 1 and base adopt trip 15,17,18,19 and screw 14 to be connected; For adapting to the demand of multiple inlet wire mode, bottom surface entrance hole 21 and side entrance hole 7 on chassis base 5, have been offered.
This cabinet adopts the complete machine damping element of wire rope damper as the vehicle-mounted hard disks video recorder, by optimizing the technical parameter and the mounting means of wire rope damper, obviously reduced vibration in the driving process, impacted influence, improved machine works stability and life-span hard disk.Compare as the vehicle-mounted hard disks video recorder of damping element with rubber, shell fragment with existing, machine natural frequency behind installation the utility model is lower, and vibration isolation erosion control performance is outstanding, and damping element has difficult aging, characteristics such as stable performance have good practical reference value.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
The foregoing description is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
