Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.

As shown in fig. 1 to 3, fig. 1 to 3 are schematic views illustrating a boarding bridge passageway in the related art. The boarding bridge comprises an inner channel 1 and an outer channel 3, wherein the outer channel 3 is telescopically sleeved outside the inner channel 1, so that the inner channel 1 and the outer channel 3 can be relatively stretched to change the length of the boarding bridge.

An air conditioner indoor unit 2 is arranged on the inner channel 1. Of course, although not shown, an air conditioner indoor unit (not shown) may be disposed on the outer duct 3. The inner passage 1 includes a top plate 11 and a partition plate 12, and the top plate 11 and the partition plate 12 are provided at intervals in the height direction of the passage.

As shown in fig. 1, the air conditioner indoor unit 2 is disposed on the inner path 1 and exposed to the ceiling 11. Because the air conditioner indoor unit 2 is exposed out of the top plate 11, the air conditioner indoor unit 2 protrudes out of the surface of the top plate 11. When the outer channel 3 stretches relative to the inner channel 1, the protruding air conditioner inner unit 2 can move and interfere with the outer channel 3, and then stretching of the inner channel and the outer channel is affected.

As shown in fig. 2, in order to prevent the air conditioner indoor unit 2 from interfering with the movement of the outer duct 3, the height of the portion of the air conditioner indoor unit 2 protruding from the ceiling panel 11 in fig. 2 is reduced. Although the inner and outer channels can be smoothly extended, when the outer channel 3 is retracted to a position where the inner channel 1 blocks the air conditioner indoor unit 2, the outer channel 3 may affect the air intake of the air conditioner indoor unit 2, thereby affecting the cooling or heating effect.

As shown in fig. 3, the bottom of the air conditioner indoor unit 2 is exposed to the partition plate 12 of the indoor duct 1. When the passenger passes through the passage, the air outlet of the air conditioner internal unit 2 can be directly blown to the top of the passenger, and poor passing experience is brought to the passenger. In addition, the exposed air conditioner internal unit can affect the beauty in the channel.

Based on the above, the embodiment of the invention provides a channel structure capable of hiding an air conditioner indoor unit, in particular to a boarding bridge channel or a boarding bridge channel.

As shown in fig. 4 and 5, fig. 4 is a schematic view illustrating a boarding bridge passageway according to an embodiment of the present invention. Fig. 5 shows a cross-section along X-X in fig. 4. The boarding bridge passageway of the embodiment of the invention comprises a passageway body 100 and an air conditioning assembly 200. The channel body 100 includes a top plate 110, two side plates 130 respectively connected to opposite sides of the top plate 110, and a bottom plate 150 disposed opposite to the top plate 110 and connected to the two side plates 130.

In one embodiment, the channel body 100 may have a substantially rectangular cross-section, but is not limited thereto.

The partition 120 is disposed in a space defined by the top plate 110, the two side plates 130, and the bottom plate 150, and is spaced apart from the top plate 110. The partition 120 thus divides the internal space of the passage body 110 into two spaces, the sandwiched space 101 and the passing area 102. The traffic area 102 is used for passengers to pass through.

The air conditioning assembly 200 is arranged in the interlayer space 101 and comprises an air conditioner indoor unit 210, an air return pipe 220 and an air outlet pipe 230; one end of the air return pipe 220 is connected to the air conditioner indoor unit 210, the other end of the air return pipe is provided with an air return opening 221, one end of the air outlet pipe 230 is connected to the air conditioner indoor unit 210, and the other end of the air outlet pipe is provided with an air outlet 231; wherein, air return 221 and air outlet 231 all face the current region 102 of passageway body 100, and air outlet 231 and air return 221 correspond the setting, and the mobility of wind is stronger, and wind circulation distance is shorter, and wind circulation cycle is shorter, and wind distance is shorter from the air conditioner, compares in the air conditioner of design on current passageway, and the same time, the number of times that wind handled through the air conditioner is more, and the heat preservation and the alternating temperature effect of passageway are better.

The air conditioner indoor unit 210 is fixedly connected to the top panel 110. In an embodiment, the fixed connection between the air conditioner indoor unit 210 and the top plate 110 may be that a mounting plate is fixedly connected with the top plate 110 by welding, and the air conditioner indoor unit 210 is fixedly connected with the mounting plate by bolts.

The channel body 100 further includes a hanger 140, and the hanger 140 is disposed in the interlayer space 101 and fixedly connected to the top plate 110. The return air pipe 220 and the outlet air pipe 230 are supported by the hanging bracket 140. It can be understood that the liquid pipe, the air pipe and the water drain pipe connected to the air conditioner indoor unit 210 are supported by the hanging bracket 140.

The spacer 120 may be detachably coupled with the hanger 140. When the partition plate 120 is connected to the hanging bracket 140, the partition plate 120 can shield the air conditioning assembly 200, so as to prevent the air conditioning assembly 200 from being exposed and affecting the beauty of the channel. When the partition 120 is separated from the hanger 140, the air conditioning unit price 200 is exposed, so that a maintenance worker can conveniently maintain the air conditioning unit price 200. By way of example, the partition 120 may be connected to the hanger 140 by a hook structure, but not limited thereto.

In one embodiment, the partition 120 may be a honeycomb aluminum plate, but is not limited thereto. The honeycomb aluminum plate has the advantages of light weight, high tensile strength, bending resistance and attractive appearance.

The hanger 140 includes a support portion 141 having a support state and a retracted state, and the support portion 141 is located on a side of the indoor unit 210 facing the partition 120 and between the indoor unit 210 and the partition 120. When in the supported state, the projection of the support portion 141 in the supported state on the partition 120 overlaps with the projection of the air conditioner indoor unit 210 on the partition 120. At this time, if the air conditioner indoor unit 210 accidentally drops from the top plate 110, the support portion 141 can support the air conditioner indoor unit 210, and the air conditioner indoor unit 210 can be prevented from directly dropping onto the partition plate 120.

When in the retracted state, there is no overlapping area between the projection of the support portion 141 in the retracted state on the partition 120 and the projection of the indoor unit 210 of the air conditioner on the partition 120. Thus, when the air conditioner needs to be repaired, the supporting part 141 can be adjusted to the contracted state, so that there is enough space for air conditioner repair and the air conditioner repair is not hindered.

In an embodiment, the movement of the supporting portion 141 between the supporting state and the contracting state may be a retractable structure, a rotatable structure or a foldable structure, which is not particularly limited in the present invention.

Of course, it is understood that the supporting portion 141 may also be fixed, that is, the supporting portion 141 is always supported below the air conditioner indoor unit 210.

As shown in fig. 5 and 6, fig. 6 is a partial bottom view of a boarding bridge passage according to an embodiment of the present invention with a partition removed.

As shown in fig. 6, the number of the air conditioning packs 200 is plural, and the plural air conditioning packs 200 are uniformly arranged along the length direction of the passage body 100. Thus, the cooling and heating of each region in the length direction of the channel body 100 can be uniform, and the temperature feeling is not different.

In addition, in a scenario where the boarding bridge includes an inner tunnel and an outer tunnel as shown in fig. 1, since the air conditioning assembly 200 can be completely hidden in the tunnel, a plurality of air conditioners uniformly arranged do not interfere with the relative movement between the inner tunnel and the outer tunnel, and excellent telescoping performance between the inner tunnel and the outer tunnel can be maintained. As shown in fig. 6, the plurality of air returns 221 of the plurality of air conditioning packs 200 are located at the first side of the partition 120, and the plurality of air returns 221 are uniformly arranged along the length direction of the duct body 100. The air outlets 231 of the air conditioning assemblies 200 are located at the second side of the partition 120, and the air outlets 231 are uniformly arranged along the length direction of the channel body 100. It is understood that one air return pipe 220 may be connected to one or more air return openings 221, and one air outlet pipe may be connected to one or more air outlets. In the present embodiment, by respectively disposing the air return opening 221 and the air outlet 231 on the first side and the second side which are oppositely disposed, the wind directions of the air return opening 221 and the air outlet 231 are also both located on both sides of the channel body 100 in the width direction, rather than in the middle area of the partition 120. Like this, when the passenger was current, the condition that cold wind or warm braw directly blow to passenger's top can not appear, has promoted passenger's current experience.

The boarding bridge passageway further comprises a grid 300, and the grid 300 is used for covering the air return opening 221 and the air outlet 231. Further, the grid 300 has a strip-like structure extending along the length of the channel. Thus, the passengers can not directly observe and determine the positions of the air return opening 221 and the air outlet 231 through visual inspection, the concealment of the air conditioning assembly is further improved, and the integrity and the attractiveness of the channel are also improved.

As shown in fig. 5, the boarding bridge passageway further includes an illumination assembly 400, and the illumination assembly 400 is adjacently disposed to the grid 300. After the lighting assembly 400 emits light, since the lighting assembly 400 is adjacent to the grid 300, the light effect of the lighting assembly 400 weakens the visual effect of the adjacent grids 310 and 320, so as to enhance the concealment of the air conditioning assembly. Further, the grid is closer to the ceiling than the lighting assembly, and the difference in height between the grid and the light strip weakens the visual effect of the grid to further weaken the visual effect of the adjacent grids 310, 320, and increases the concealment of the grid to further enhance the concealment of the components associated with the air conditioning assembly.

As shown in fig. 6 and 7, fig. 7 is a partially enlarged view of a portion a in fig. 5. The lighting assembly 400 includes a light source 410, a light-transmitting band 420, and a lamp housing 430, the lamp housing 430 is fixedly connected to the hanger 140, and the light source 410 is disposed in the lamp housing 430. The light-transmitting tape 420 is detachably attached to the opening of the lamp housing 430 to enclose the light source 410 within the lamp housing 430. The light source 410 effects illumination of the traffic region 102 through the light transmissive strip 420.

The light transmitting strip 420 is strip-shaped and extends along the length of the channel, the light transmitting strip being adjacent to the grid. So, although the light source still sets up at the interval in length direction, because the sheltering from of printing opacity area, in visual effect, can not see the light source of interval arrangement, but a banding rectangular lamp, the visual effect of passageway on the whole is better.

In one embodiment, the light source 410 is disposed adjacent to the air outlet and the air return, such that the air from the air outlet and the air return can be used to cool the light source, thereby increasing the heat dissipation of the light source and increasing the lifetime of the light source.

In one embodiment, the lamp housing 430 includes a bearing portion 431, and the diaphragm 120 is overlapped on the bearing portion 431. As described above, the partition 120 may be overlapped on the bearing part 431 or detachably connected to the hanger 140 by the hook structure, as shown in fig. 5 and 7.

Referring to fig. 5 again, the side plate 130 includes a ventilation window 131 having an open state and a closed state, and the ventilation window 131 is communicated with the passing area 102. When the ventilation window 131 is in the open state, the external air can enter the channel, and the air in the channel can be supplemented and purified. By setting the replacement gas window 131, fresh air can be timely supplemented to the channel of the embodiment of the present invention.

As an example, the ventilation window 131 may be switched between the open state and the closed state by opening and closing the one side window 510. For example, the side window 510 may be opened or closed by a push-pull operation. The side window 510 is rotatably connected to the side plate 130, when the side window 510 rotates outwards, the side window 510 is opened, and the ventilation window 131 is in an open state; when the side window 510 is rotated inward, the side window 510 is closed, and the ventilation window 131 is opened and closed.

The movement of the side window 510 may be electrically driven and controlled by the center stack. Specifically, the side plate 130 is provided with a telescopic mechanism 530 at a position adjacent to the ventilation window 131, and one end of the thrust chain 520 is connected to the side window 510, and the other end is connected to the telescopic mechanism 530. When the telescopic mechanism 530 winds the thrust chain 520, the thrust chain 520 can drive the side window 510 to close. When the telescoping mechanism 530 releases the thrust chain 520, the thrust chain 520 pushes against the side window 510 to open.

As shown in fig. 8, fig. 8 is a partial side view of a boarding bridge passageway according to an embodiment of the present invention. The side panel 130 includes a frame 132 and a glass 133 mounted on the frame. The frame 132 of the embodiment of the present invention includes a tie bar structure 1321, and the tie bar structure 1321 is matched with a glass sidewall, so that the boarding bridge passage of the embodiment of the present invention is more beautiful.

In another aspect of the present invention, there is also provided a boarding bridge including the boarding bridge tunnel of any one of the above embodiments. Therefore, the boarding bridge of the embodiment of the invention has all the advantages and beneficial effects of any one of the above embodiments, and the details are not repeated here.

In summary, the boarding bridge passage and the boarding bridge of the embodiment of the invention have the advantages and beneficial effects that:

according to the boarding bridge passage provided by the embodiment of the invention, by adopting the technical means that the air conditioning assembly 200 is arranged in the interlayer space 101, and the air return inlet 221 and the air outlet 231 face the passing area 102 of the passage body 100, the air conditioning indoor unit 210, the air return pipe 220 and the air outlet pipe 230 of the air conditioning assembly 200 are all hidden in the interlayer space 101, are not exposed out of the top plate 110 and the partition plate 120, and the problems of influence on the expansion and contraction of the inner and outer passages and poor air inlet effect in the related technology are effectively solved. In addition, the hidden air conditioner also improves the aesthetic feeling of the channel.
