In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, following will be combined with the drawings in the embodiments of the present invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is the structural schematic diagram for the heat dissipation window assembly that the embodiment of the present invention one provides.Fig. 2 is the perspective view of the explosion for the heat dissipation window assembly that the embodiment of the present invention one provides.Fig. 3 is the partial enlargement diagram in Fig. 1 at A.As shown in Figure 1 to Figure 3, heat dissipation window assembly provided in this embodiment, for radiating for heat source, heat dissipation window assembly specifically includes shell 1, cooling fin 2 and driving mechanism 3, at least one heat release hole 11 is offered on shell 1, driving mechanism 3 and cooling fin 2 connect, for driving cooling fin 2 to cover heat release hole 11 or removing from heat release hole 11.
Specifically, shell 1 generally can perhaps the surface of the shell of other movable fixtures or at least part of shell thus shell 1 be usually located at the outside of unmanned vehicle or other movable fixtures for unmanned vehicle.Further, it is to be appreciated that heat dissipation window assembly
It can be independent unit, at this point, being split type structure between the shell 1 and the shell of unmanned vehicle of heat dissipation window assembly, and can be removed from the shell of unmanned vehicle, to carry out independent maintenance or replacement.
And as a preferred mode, since the shell 1 in heat dissipation window assembly is general and the shell of the packaged types device such as unmanned vehicle is structure as a whole, so the shell 1 of heat dissipation window assembly can also include opening and lid is located at the bottom plate on being open, heat release hole 11 is provided on bottom plate.The bottom plate to be radiated in window assembly in this way can be removed from opening, individually to place under repair maintenance to heat release hole, cooling fin or driving mechanism.Wherein, the shell 1 of window assembly of radiating can both be structure as a whole with the shell of unmanned vehicle, or the cage connection as dismountable unit and unmanned vehicle.
At least one heat release hole 11 is offered on the shell 1 of heat dissipation window assembly, the heat release hole 11 penetrates through 1 inner surface of shell and outside face two sides, thus air can be flowed inside and outside shell 1 by the heat release hole 11, so that e.g. device or equipment are aerated heat dissipation to the heat source in shell 1.In addition, heat dissipation window assembly further includes having cooling fin 2 and driving mechanism 3, driving mechanism 3 and cooling fin 2 link together, and are able to drive the movement of cooling fin 2, so that cooling fin 2 is covered on heat release hole 11 and closes heat release hole 11；Or removed from heat release hole 11, to allow heat release hole 11 that in opened condition, and normal heat dissipation work can be carried out.
Wherein, the heat release hole 11 being provided on shell 1, either being also possible to discharge 1 internal gas flow of shell to extraneous air outlet for guiding air-flow to enter the air intake vent inside shell 1.In the work of the movable equipments such as unmanned vehicle, cooling fin 2 is removed from heat release hole 11, so that heat release hole 11 is in opened condition, and carries out proper heat reduction.And in order to avoid extraneous dust and steam in open heat release hole 11 from entering inside shell 1, and the equipment or element that are disposed inside shell 1 are impacted, when the movable equipments such as unmanned vehicle are in landing or transport or flight meets with the states such as bad environments situation on the way, cooling fin 2 in heat dissipation window assembly can be covered on heat release hole 11 under the driving of driving mechanism 3, so that heat release hole 11 be allowed to be in close state.At this point, extraneous dust and steam can be stopped by cooling fin 2, thus the inside of shell 1 can not be entered by heat release hole 11.
In general, the radiating efficiency in order to guarantee heat release hole 11, cooling fin 2 and heat release hole 11 are at least two, and the quantity of cooling fin 2 and the quantity of heat release hole 11 are equal, and each cooling fin 2 corresponds to a heat release hole 11.In general, heat release hole 11 can be arranged in one directly
On line, and the position setting of the corresponding heat release hole 11 of cooling fin 2, so that driving mechanism drives cooling fin 2.
Specifically, in order to drive cooling fin 2 mobile, driving mechanism 3 generally comprises driving member 31 and the driving assembly 32 for being capable of providing driving force, cooling fin 2 is arranged on driving member 31, and driving assembly 32 and driving member 31 connect, in this way when needing to change the open and-shut mode of heat release hole 11, driving assembly 32 can be used to driving driving member 31 and move, and drive cooling fin 2 to move in turn.
And in order to allow heat release hole 11 under different use occasions in the different state such as closing or opening; the movement of driving mechanism 3 would generally follow certain mechanism; such as the driving assembly 32 in driving mechanism 3 can be connected with electrical control element; and driving force size and the driving force direction etc. that driving assembly 32 controlled by command signal that user is issued; or the shape or structure of driving assembly 32 are directly changed by physical actions such as temperature, so that the driving force of driving assembly 32 be made to generate variation etc..
Such as, a kind of optional embodiment as driving assembly 32, driving assembly 32 may include at least one memory alloy part 321, one end of memory alloy part 321 and shell 1 are fixed, the other end and driving member 31 of memory alloy part 321 connect, and length between the both ends of memory alloy part 321, when changing, driving member 31 drives cooling fin 2 to move under the pulling of memory alloy part 321.Wherein, memory alloy part 321 is to be formed by structural member by marmem, when external environment changes, its deformation under initial environment can be eliminated, to be restored to the original-shape before deformation.Therefore, it is possible to allow the shape of memory alloy part 321 to change by changing environmental parameter locating for the memory alloy parts such as temperature, and drive driving member 31 and cooling fin 2 mobile；Alternatively, can also be by the change of other environment parameters such as energization, so that memory alloy part 321 generates change in shape.
Specifically, due to heat dissipation window assembly be used for in shell 1 device or element radiate, so the packaged types such as unmanned vehicle device is at work, the environment temperature locating for window assembly that radiates can generate corresponding variation.Therefore, it is possible to directly control or drive the shape of memory alloy part 321 to change by the change of temperature.As a kind of optional drive control mode of memory alloy part 321, memory alloy part 321 and heat source have heat transfer, and the length between the both ends of memory alloy part 321 can change with the temperature change of memory alloy part 321.
Wherein, memory alloy part 321 generally receives what heat source was issued by way of heat transfer
Heat, such as can directly be connected with heat sources such as heater elements, to realize heat transfer, or by Heat Conduction Materials such as heat-conducting glue or heat pipes to realize heat transfer etc. indirectly.
In order to improve the susceptibility that the shape of memory alloy part 321 changes temperature, memory alloy part 321 is typically rod-shaped or linear, and select the direction of its change in shape consistent with its length direction, thus when temperature changes, memory alloy part 321 has more apparent deformation in length direction, therefore the both ends of memory alloy part 321 can be connected between shell 1 and driving member 31, when the temperature change of memory alloy part 321, length between 321 both ends of memory alloy part has larger change, such as obvious to extend or obviously shorten.With the change of length between 321 both ends of memory alloy part, memory alloy part 321 can drive driving member 31 and cooling fin 2 mobile, to change the open and-shut mode of heat release hole 11.
In general, the shape and structure of memory alloy part 321 and the deformation process of memory alloy part 321 can be simplified in order to avoid memory alloy part 321 caused by due to 321 deformation process of memory alloy part is excessively complicated deforms phenomenon not in place；Simultaneously as the material property of memorial alloy itself, memory alloy part 321 would generally be in initial lower temperature with certain deformation, and when through heat transfer or when the modes heat temperature raising such as directly heating, original deformation disappears, to restore the shape before deformation.Therefore, the distance between both ends of memory alloy part 321 should increase with the temperature of memory alloy part 321 and shorten or extend.The initial deformation of memory alloy part 321 can be allowed for simple stretcher strain in this way, in this way after memory alloy part 321 is heated, original stretching or compressive deformation can disappear, so that memory alloy part 321 restores to original length.The process restored from deformation state of the structure of memory alloy part 321 and memory alloy part 321 in this way is relatively simple, and the reliability of driving is higher.
In the present embodiment, because the packaged types such as unmanned vehicle mobile device is at work, equipment or element inside shell 1 can generate amount of heat, form heat source, thus change the shape of memory alloy part 321 by the temperature of memory alloy part 321, and the mode of driving member 31 and the movement of cooling fin 2 is thus driven, it can change and know the working condition of the equipment such as unmanned vehicle according to the temperature of memory alloy part 321, and control the open and-shut mode of heat release hole 11.By taking unmanned vehicle as an example, under general state, the heat release hole 11 for the window assembly that radiates is closed, and cooling fin 2 is covered on heat release hole 11, and is normal condition for driving the memory alloy part 321 of cooling fin 2；When the window assembly that radiates radiates to heat source, memory alloy part 321 can generate length variation because heated, and control cooling fin 2 and remove from heat release hole 11, make heat release hole
11 in opened condition；And when the equipment such as unmanned vehicle stop working, then the operation element inside shell 1 no longer generates heat, at this time, the temperature of memory alloy part 321 declines, its shape also returns back to the shape under normal temperature, and control cooling fin 2 is covered on heat release hole 11 again, and dust or raindrop etc. is avoided to enter inside shell 1 from heat release hole 11.The deformation of memory alloy part 321 is controlled by temperature in this way, can the open and-shut mode automatically to heat release hole 11 be changed, issue instruction without user or control device, adaptivity is stronger.
And another drive control mode as memory alloy part 321, it can also include controller (not shown) in heat dissipation window assembly, it is electrically connected between controller and memory alloy part 321, and the length between the both ends of memory alloy part 321 can change with the energized state of memory alloy part 321.At this point it is possible to which Nitinol etc. is selected to constitute memory alloy part, when energized, Nitinol can generate contraction, thus the shape of memory alloy part 321 can change with energized state.
With it is aforementioned by temperature change control memory alloy part 321 deform in the way of it is similar, it is mobile for the ease of driving driving member 31 and cooling fin 2, memory alloy part 321 is usually rod-shaped or linear, thus when temperature changes, memory alloy part 321 has more apparent deformation in length direction, the both ends along its length of memory alloy part 321 are connected with shell 1 and driving member 31 respectively in this way, and change the length of memory alloy part 321 by being powered or powering off, driving member 31 and cooling fin 2 can be driven to realize movement, realize the opening and closing operations of heat release hole 11.
It is controlled since the deformation of memory alloy part 321 is switched on state, may include having controller in heat dissipation window assembly, be electrically connected between controller and memory alloy part 321, and electric current can be passed through into memory alloy part 321.The energized state that memory alloy part 321 can be controlled by electric signal that controller is issued in this way, the movement of cooling fin 2 is driven with this.
Due to the presence of controller, user can be by issuing command signal to controller, to change the open and-shut mode of heat release hole 11, or is controlled by the control logic of the movable fixtures such as unmanned vehicle itself.Control can be realized to the open and-shut mode of heat release hole 11 in heat dissipation window assembly according to different requirements or situation in this way, control freedom degree is higher.
In general, only in need when being radiated, just in the way of deformation of memory alloy part 321 etc., heat release hole 11 is opened for driving assembly 32；And under general state, the movable fixtures such as unmanned vehicle be in storage perhaps off-mode at this time in order to avoid extraneous dust or steam
Enter inside device Deng from heat release hole 11, heat release hole 11 generally remains off, thus, the opposite another active force of force direction when driving assembly 32 should be able to apply and open heat release hole 11, so as to keep heat release hole 11 to close under 2 normal condition of cooling fin, either after heat dissipation, re-closes and be covered on heat release hole 11.
It is general, since generated driving force is typically small when memory alloy part returns back to original state by deformation state, so when driving assembly 32 drives cooling fin 2 to reset and close heat release hole 11, in order to avoid driving hypodynamic phenomenon, driving assembly 32 can also assist providing by other components the driving force contrary with the power of heat release hole is opened, to guarantee that heat release hole 11 can be with normal switching-off.Specifically, driving assembly 32 can provide the active force contrary with the power of heat release hole 11 is opened by various ways.
As a kind of optional embodiment, in order to apply the power opposite with force direction when opening heat release hole 11, driving assembly 32 generally further includes elastic component 322, one end of the separate memory alloy part 321 of driving member 31 is arranged in elastic component 322, one end of elastic component 322 is connect with shell 1, the other end of elastic component 322 is connect with driving member 31, and the active force that generates by self-deformation of the elastic force direction of elastic component 322 and memory alloy part 321 is contrary.
In this way, cooling fin 2 can be generally covered on heat release hole 11 under the effect of the elastic force of elastic component 322, so that heat release hole 11 is in off state, and after memory alloy part 321 generates deformation due to temperature changes or is powered, the deforming force of memory alloy part 321 can overcome the elastic force of elastic component 322, and drive driving member 31 mobile, and cooling fin 2 is made to remove and radiate from heat release hole 11, and elastic component 322 is driven the active force of part 31 at this time, itself constantly gathers elastic potential energy；When heat dissipation is completed, when needing to close heat release hole 11, memory alloy part 321 restores to original shape, and driving member 31 loses the active force of memory alloy part 321, original position can be returned back under the effect of the elastic potential energy of elastic component 322, be covered on heat release hole 11 again.
Optionally, general elastic component 322 can be spring, such as perhaps the deformation direction of tension spring etc. and spring is parallel with the deformation direction of memory alloy part 321 or is located along the same line for compression spring, so as to provide the active force contrary with memory alloy part 321.
Due to being connected with elastic component 322 on driving assembly 32, it is thus possible to before memory alloy part 321 does not have to generate deformation or after deformation, driving member 1 be fixed on to original position
It sets, it is thus possible to guarantee that heat release hole 11 is in close state in the occasions such as storage, avoid dust or extraneous steam enters heat release hole 11.
In addition, can smoothly push cooling fin 2 mobile when in order to keep driving member 31 mobile, also can have a variety of different connection types and relative position between cooling fin 2 and driving member 31 and between cooling fin 2 and shell 1.Such as, can be hinged by shaft between one end and shell 1 of cooling fin 2, and cooling fin 2 and one end of the separate shaft of driving member 31 have and are flexibly connected, when driving member 31 moves, cooling fin 2 changes relative to the angle of shell 1, to cover heat release hole 11 or remove from heat release hole 11.As long as cooling fin 2 changes itself relative position between heat release hole 11 by way of rotation in this way, it is in open or close state that heat release hole 2, which can just be made, structure is relatively simple, and be not susceptible between cooling fin 11 and heat release hole 2 displacement, dislocation phenomena such as, to heat release hole 2 open or close operation it is more reliable.
In the present embodiment, heat dissipation window assembly is used to radiate for heat source, and heat dissipation window assembly specifically includes shell, cooling fin and driving mechanism, at least one heat release hole is offered on shell, driving mechanism is connected with cooling fin, for driving cooling fin covering heat release hole or removing from heat release hole.Heat dissipation window assembly in this way can open heat release hole when needing to radiate, and close heat release hole in other conditions, and extraneous dust and steam etc. is avoided to enter.
Fig. 4 is the structural schematic diagram of driving assembly in another heat dissipation window assembly provided by Embodiment 2 of the present invention.As shown in Figure 4, in the present embodiment, the overall structure of heat dissipation window assembly is similar in previous embodiment one with working principle, the difference is that, in order to apply the active force contrary with power when opening heat release hole 11, guarantee the smooth closing of heat release hole 11, driving assembly 32 includes the first memory alloy part 321a and the second memory alloy part 321b, first memory alloy part 321a and the second memory alloy part 321b is separately positioned on the opposite end of the moving direction of driving member 31, and first the length of change direction and the second memory alloy part 321b that changes with temperature of length of memory alloy part 321a change in the opposite direction with what temperature changed.
At this time, first memory alloy part 321a and the second memory alloy part 321b can generate corresponding deformation by the change of sense temperature, the concrete mode that the shape of its single memory alloy part changes with temperature is described in detail in the aforementioned embodiment, and details are not described herein again.And in this implementation, the change trend that the shape of the first memory alloy part 321a and the second memory alloy part 321b in driving assembly 32 vary with temperature is exactly the opposite, such as works as temperature
When degree increases, the first memory alloy part 321a generates the trend of elongation, and the second memory alloy part 321b generates the deformation tendency of shortening simultaneously.First memory alloy part 321a and the second memory alloy part 321b can be separately positioned on to the opposite end of the moving direction of driving member 31 in this way.Since the deformation tendency that the first memory alloy part 321a and the second memory alloy part 321b change with temperature is opposite, so when temperature changes, such as when increasing, first memory alloy part 321a elongation, and the second memory alloy part 321b shortens, either the first memory alloy part 321a shortens, the second memory alloy part 321b elongation.In this way, driving member 31 will be towards the Fang Yidong shortened in two memory alloy parts, and drive cooling fin 2 mobile.And when temperature is restored to original normal temperature, then the first memory alloy part 321a and the equal direction of the second memory alloy part 321b and original opposite Direction distortion, so that driving member 31 be driven to reset.No matter cooling fin 2 is needed towards the movement of which direction in this way, first memory alloy part 321a and the second memory alloy part 321b can apply active force to the direction, it is mobile to the direction to drive driving member 31, so that be respectively completed heat release hole 11 turns on or off operation.
