Description
Technical field
The utility model belongs to unmanned plane equipment technology field, is related to a kind of hatch door controlling switch, specifically a kind of double
Insure the unmanned engine room door switch of cutter driving.
Background technology
Unmanned plane requires that each hatch door tightly closes in flight course, but in some cases, it is desirable to the controllable unlatching of hatch door,
Such as during unmanned plane recovery, it is desirable to control umbrella hatch door to open.After parachuting unmanned plane opens umbrella hatchcover in the air, umbrella hatchcover is in gas
Turned in the presence of stream and throw away extractor parachute, extractor parachute, which is taken out of after pack, opens main chute, the parachute after opening with
Unmanned plane steadily declines landing with less speed.Parachuting unmanned plane typically opens umbrella hatchcover by two ways:One kind is logical
Cross and fly the unlatching that control machine control electric control lock realizes umbrella hatchcover；Another way is that the umbrella tied up on umbrella hatchcover is cut off with cutter
Rope, realizes the unlatching of umbrella hatchcover.The former requires that the output voltage for flying control electromechanical source is high, but umbrella hatchcover occurs in catastrophic failure and beats
The probability for opening failure is high；The overload capacity of electric control lock is small simultaneously, occurs that electric control lock can not be normal in the case of complicated high overload
The situation of work.The latter's complex operation when unmanned aerial vehicle loads pack, it is not easy to grasp the tightness of tie-down strap, automatically
Change degree is low.
Utility model content
Technical problem to be solved in the utility model is the shortcomings that overcoming prior art, there is provided a kind of dual fail-safe cutting
The unmanned engine room door switch of device driving, overcoming existing unmanned plane umbrella hatchcover to be opened in catastrophic failure, the probability to fail is high to ask
Complex operation when inscribing, while reducing aerial pickup pack, the big deficiency of workload.
Opened in order to solve the above technical problems, the utility model provides a kind of unmanned plane hatch door of dual fail-safe cutter driving
Close, including cutting body, locking bail, sheath, cutter and ejector pin, the side of the cutting body is provided with cuts as described in two confessions
The cavity of cutter installation, the opposite side relative to installation cutter of the cutting body is provided with cutting body mounting seat, described
Cutting body mounting seat is made up of two ear mounts be arrangeding in parallel, and the locking bail is installed by bearing pin between two ear mounts,
The upper end that the locking bail is located at rotating shaft is provided with the coupler body being connected with umbrella hatchcover clasp, and the lower end that the locking bail is located at rotating shaft is
Thrust face, communicated between the thrust face and the cutter installation cavity of the cutting body provided with pin-and-hole, it is described
Cutter in cutter installation cavity is acted on external force on tight locking button by the ejector pin in pin-and-hole, and the cutter leads to
Cross the interior intracavitary that sheath is fixed on cutting body.
The technical scheme that the utility model further limits is：The unmanned plane hatch door of foregoing dual fail-safe cutter driving is opened
Close, the tight locking button is provided with spring mounting post relative to the other end provided with coupler body, passes through the drawing in spring mounting post
Spring connects with the cutter body phase, resets locking bail using the pulling force of extension spring.
The unmanned engine room door switch of foregoing dual fail-safe cutter driving, two cutter installation cavities are in same
On horizontal plane, and in two cavitys installation cutter specifications parameter it is identical, the resistance of cutter is 2-3.5 Ω, safe current
Continue 1min for DC current 50mA to misfire, firing current is 450~850mA, is enough to realize hatch door using single cutter
Open.
Further, the unmanned engine room door switch of foregoing dual fail-safe cutter driving, the ejector pin diameter are not more than
3mm, length are not less than 21.5mm.
The beneficial effects of the utility model are：The utility model small volume, control mode are simple, excite what cutter needed
Electrical power is small, and cutter thrust output is big, and umbrella cabin door can be also opened in the case of complicated high overload；Cut by dual fail-safe
The unmanned engine room door switch of cutter driving, the opening of hatch door can be controlled by cutter, simultaneously because being carried out using double cutters
Work, improve the reliability of hatch door unlatching.

Embodiment
Embodiment 1
The present embodiment provides a kind of unmanned engine room door switch of dual fail-safe cutter driving, as shown in Figure 1 to Figure 3, including
Body 1, locking bail 2, sheath 3, cutter 4 and ejector pin 5 are cut, the side for cutting body is provided with by two for cutter installation
Cavity, the opposite side relative to installation cutter for cutting body are provided with cutting body mounting seat, and cutting body mounting seat is by two
The individual ear mount be arrangeding in parallel is formed, and two cutter installation cavities are in same level, and that is installed in two cavitys cuts
Cutter specifications parameter is identical, and the resistance of cutter is 2-3.5 Ω, and safe current is that the lasting 1min of DC current 50mA misfire,
Firing current is 450~850mA；The upper end of rotating shaft is located at by rotating shaft installation locking hook, locking bail between two ear mounts 10
Provided with the coupler body being connected with umbrella hatchcover clasp, the lower end that locking bail is located at rotating shaft is thrust face, thrust face and cutting
Communicated between the cutter installation cavity of body provided with pin-and-hole, the cutter in cutter installation cavity passes through the ejector pin in pin-and-hole
External force is acted on tight locking button, ejector pin diameter is not more than 3mm, and length is not less than 21.5mm；Tight locking button is relative to provided with coupler body
The other end be provided with spring mounting post, connected by the extension spring 6 in spring mounting post and cutter body phase, cutter passes through
