The bottom side 313 faces the bottom of the vehicle 1000 and is connected between the first front side 311 and the first rear side 312. When the door assembly 300 is closed relative to the vehicle body 200 , the first front side 311 is arranged opposite to the front edge 202 of the door opening 201 , the first rear side 312 is arranged opposite to the rear edge 203 of the door opening 201 , and the bottom side 313 is arranged opposite to the bottom edge 205 of the door opening 201 .

[0034] The vehicle window 320 is connected to the vehicle door 310 and can rotate relative to the vehicle body 200 driven by the vehicle door 310. The side of the vehicle window 320 includes a second front side 323, a second rear side 324 and a top side 325. Along the length direction of the vehicle window 320 (the Y-axis direction in the figure), the second front side 323 and the second rear side 324 are arranged opposite to each other. The top side 325 faces the top of the vehicle 1000 and is connected between the second front side 323 and the second rear side 324.

[0035] In this embodiment, the vehicle window 320 includes a vehicle window glass 321 and a vehicle window edging 322. Exemplarily, the vehicle window glass 321 may be a laminated glass. The vehicle window edging 322 covers the periphery of the vehicle window glass 321. The vehicle window edging 322 includes a second front side edge 323, a second rear side edge 324, and a top side edge 325. Exemplarily, the vehicle window edging may be made of at least one of polyurethane (PU), thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC), and the like.

[0036] In some other embodiments, the vehicle window 320 is a borderless vehicle window, that is, the vehicle window 320 does not include a vehicle window edging 322 , and the vehicle window 320 only includes a vehicle window glass 321 . In this case, the vehicle window glass 321 includes a second front side edge 323 , a second rear side edge 324 and a top side edge 325 .

[0038] The ventilation device 100 is connected to the edge of the vehicle door 201 or the side of the vehicle door assembly 300. Specifically, the ventilation device 100 is connected to the edge of the vehicle door 201, the side of the vehicle door 310, or the side of the vehicle window 320. Next, for the sake of convenience, the structure of the ventilation device 100 is described by taking the case where the ventilation device 100 is connected to the top side 325 of the vehicle window 320 as an example.

[0039] See also Figure 3 and Figure 4 , Figure 3 for Figure 1 The schematic cross-sectional structure diagram of the first ventilation device of the vehicle shown is in a closed state, Figure 4 for Figure 3 A schematic diagram of the cross-sectional structure of the ventilation device shown in the open state.

[0040] The ventilation device 100 includes a frame 10, a sound insulation member 20, a control member 30, and a processor (not shown). The frame 10 is provided with a ventilation passage 40. The sound insulation member 20 is provided in the ventilation passage 40. The control member 30 is provided in the frame 10, and can close or open the ventilation passage 40. The processor is connected to the control member 30, and controls the control member 30 to close or open the ventilation passage 40.

[0041] The ventilation device 100 has an open state and a closed state. When the ventilation device 100 is in the open state, the control member 30 opens the ventilation channel 40, and the ventilation channel 40 connects the inside and outside of the vehicle 1000. The air inside the vehicle 1000 can flow to the outside of the vehicle 1000 through the ventilation channel 40, and the air outside the vehicle 1000 can also flow to the inside of the vehicle 1000 through the ventilation channel 40, that is, the air inside the vehicle 1000 and the air outside the vehicle 1000 can be mutually circulated through the ventilation channel 40. At this time, the sound insulation member 20 located in the ventilation channel 40 can eliminate the noise entering the inside of the vehicle 1000 through the ventilation channel 40, reduce the noise inside the vehicle 1000, and improve the driving experience of the driver and the riding experience of the passengers.

[0042] When the ventilation device 100 is in the closed state, the control component 30 closes the ventilation passage 40 and blocks the inside and outside of the vehicle 1000. The air inside the vehicle 1000 cannot flow from the ventilation passage 40 to the outside of the vehicle 1000, and the air outside the vehicle 1000 cannot flow from the ventilation passage 40 to the inside of the vehicle 1000. That is, the air inside the vehicle 1000 and the air outside the vehicle 1000 cannot circulate with each other through the ventilation passage 40.

[0043] The ventilation passage 40 includes a main ventilation passage 401, a first ventilation opening 402, and a second ventilation opening 403. Along the width direction of the vehicle 1000 (the X-axis direction in the figure), the first ventilation opening 402 and the second ventilation opening 403 are respectively located at opposite ends of the main ventilation passage 401. The first ventilation opening 402 faces the inside of the vehicle 1000, and the second ventilation opening 403 faces the outside of the vehicle 1000. The control member 30 is disposed at the first ventilation opening 402, the second ventilation opening 403, or the main ventilation passage 401.

[0044] When the control member 30 opens the ventilation passage 40, the main ventilation passage 401 is connected to the first ventilation port 402 and the second ventilation port 403. The first ventilation port 402 is connected to the inside of the vehicle body 200 and the main ventilation passage 401, and the second ventilation port 403 is connected to the main ventilation passage 401 and the outside of the vehicle body 200, so that the air inside the vehicle body 200 and the air outside the vehicle body 200 can be mutually circulated through the ventilation passage 40. For example, Figure 4As shown, when the control member 30 opens the ventilation passage 40 , the air flow A outside the vehicle 1000 can enter the inside of the vehicle 1000 through the ventilation passage 40 .

[0045] The ventilation passage 40 includes a first passage inner wall 41 and a second passage inner wall 42. Along the width direction of the ventilation passage 40 (Z-axis direction in the figure), the first passage inner wall 41 and the second passage inner wall 42 are spaced apart and arranged opposite to each other.

[0046] In this embodiment, the frame 10 is a vehicle window frame. The frame 10 is connected to the vehicle door 310 and is located on one side of the vehicle door 310 near the top side edge 325 of the vehicle window edging 322. It can be understood that when the ventilation device 100 is connected to the edge of the vehicle door 201, the frame 10 is a vehicle body frame. When the ventilation device 100 is connected to the side of the vehicle door 310, the frame 10 is a vehicle door frame. The specific structure of the frame 10 can be adaptively changed according to the position of the ventilation device 100, and this application does not make specific restrictions on this.

[0047] The frame 10 includes a top plate 11 and a bottom plate 12. The top plate 11 and the bottom plate 12 are spaced apart and arranged opposite to each other along the height direction (Z-axis direction in the figure) of the vehicle 1000. The bottom plate 12 is located between the top plate 11 and the vehicle window edging 322, and clamps the top side edge 325 of the vehicle window edging 322. In some other embodiments, the vehicle window 320 may not include the vehicle window edging 322, in which case the bottom plate 12 clamps the top side edge 325 of the vehicle window 320.

[0048] A ventilation passage 40 is formed between the top plate 11 and the bottom plate 12. The top plate 11 includes a first passage inner wall 41. The bottom plate 12 includes a second passage inner wall 42. Along the width direction of the vehicle 1000 (the X-axis direction shown in the figure), the top plate 11 and the bottom plate 12 form a first vent 402 at one end facing the inside of the vehicle 1000, and the top plate 11 and the bottom plate 12 form a second vent 403 at one end facing the outside of the vehicle 1000. The cross-sectional shape of the ventilation passage 40 may be U-shaped, V-shaped, semicircular, door-shaped, and the like. In the present embodiment, the cross-sectional shape of the ventilation passage 40 may be U-shaped.

[0049] The sound insulation 20 can be arranged in the main ventilation duct 401, the first ventilation port 402 or the second ventilation port 403. In this embodiment, the sound insulation 20 is arranged on the inner wall 41 of the first channel and is spaced apart from the inner wall 42 of the second channel. There are two sound insulation 20, one sound insulation 20 is arranged in the first ventilation port 402, and the other sound insulation 20 is arranged in the second ventilation port 403. The sound insulation 20 can be made of at least one of the sound-absorbing materials such as chemical (physical) cross-linked polyethylene foam, irradiation cross-linked polypropylene foam, corrugated cotton, glass fiber cotton, butyl rubber and sound-absorbing cotton.

[0050] The control member 30 is disposed in the ventilation channel 40 and on the second channel inner wall 42, and is disposed opposite to the sound insulation member 20. In some other embodiments, the sound insulation member 20 may also be disposed on the second channel inner wall 42 and spaced apart from the first channel inner wall 41. In this case, the control member 30 may be disposed on the first channel inner wall 41 and is disposed opposite to the sound insulation member 20.

[0051] When the control member 30 opens the ventilation passage 40, the control member 30 is spaced apart from the sound insulation member 20, and the air flow A can pass through the gap between the control member 30 and the sound insulation member 20. When the control member 30 closes the ventilation passage 40, the control member 30 abuts against the sound insulation member 20, and at this time, there is no gap between the control member 30 and the sound insulation member 20. In this embodiment, there are two control members 30, one control member 30 is disposed at the first ventilation opening 402 and is disposed opposite to one sound insulation member 20, and the other control member 30 is disposed at the second ventilation opening 403 and is disposed opposite to the other sound insulation member 20.

[0052] When the ventilation device 100 is in the closed state, Figure 3 The two control members 30 respectively close the two ends of the ventilation passage 40 , that is, close the first ventilation opening 402 and the second ventilation opening 403 , so that the air flow A outside the vehicle 1000 cannot enter the inside of the vehicle 1000 through the ventilation passage 40 .

[0053] When the ventilation device 100 is switched from the closed state to the open state, Figure 4 The two control components 30 open the two ends of the ventilation channel 40 respectively, that is, open the first vent 402 and the second vent 403, so that the air flow A outside the vehicle enters the ventilation channel 40 through the second vent 403, and then enters the inside of the vehicle 1000 through the first vent 402, thereby realizing the circulation of air inside and outside the vehicle 1000.

[0054] In other possible embodiments, there may be one control member 30, which may be located at the first vent 402, the main vent 401, or the second vent 403. The switching of the vent 40 between the closed state and the open state may be controlled by one control member 30, thereby reducing production costs and optimizing the use space of the vehicle 1000.

[0055] Each control member 30 includes a control body 31, an abutment body 32, an elastic body 33 and a telescopic rod 34. The control body 31 is disposed on the inner wall 42 of the second channel. One end of the telescopic rod 34 is connected to the control body 31. The elastic body 33 is sleeved on the outer side of the telescopic rod 34. The abutment body 32 is connected to the other end of the telescopic rod 34. The elastic body 33 and the telescopic rod 34 are located between the control body 31 and the abutment body 32, and are connected between the control body 31 and the abutment body 32.

[0056] In this embodiment, the control element 30 may be an electromagnetic relay. The control body 31 may be an electromagnet and is electrically connected to a processor (not shown). The control body 31 has a power-on state and a power-off state. When the processor powers the control body 31, the control body 31 is in the power-on state and the control body 31 is magnetic. When the processor does not power the control body 31, the control body 31 is in the power-off state, that is, the control body 31 is not powered and the control body 31 is magnetically neutral.

[0057] The abutment body 32 can be made of a soft magnetic material, for example, the abutment body 32 can be made of pure iron. When the control body 31 is in a powered state and is magnetic, the abutment body 32 will be magnetized by the control body 31 and become magnetic. At this time, the abutment body 32 will move toward the control body 31 under the action of the magnetic force of the control body 31, and the abutment body 32 will compress the elastic body 33 and the telescopic rod 34. The abutment body 32 is spaced apart from the sound insulation member 20. The length of the elastic body 33 after being compressed by the abutment body 32 is the first length, and the length of the telescopic rod 34 after being compressed by the abutment body 32 is the third length. The first length can be equal to the third length.

[0058] When the control body 31 is in a power-off state and is magnetically neutral, the abutment body 32 will be demagnetized due to the magnetic neutrality of the control body 31. After demagnetization, the abutment body 32 is magnetically neutral. At this time, the abutment body 32 will move away from the control body 31 under the action of the elastic restoring force of the elastic body 33, and the elastic body 33 and the telescopic rod 34 will extend until the abutment body 32 abuts against the sound insulation member 20. Among them, the length of the elastic body 33 is the second length, and the second length is greater than the first length. The length of the telescopic rod 34 is the fourth length, and the fourth length is greater than the third length. The second length is equal to the fourth length. Exemplarily, the elastic body 33 can be a spring.

[0059] In other possible embodiments, the control member 30 may not be disposed opposite to the sound insulation member 20, but may be disposed opposite to the first channel inner wall 41. When the control member 31 is in a powered-on state, the abutting member 32 may be spaced apart from the first channel inner wall 41. When the control member 31 is in a powered-off state, the abutting member 32 may abut against the first channel inner wall 41.

[0060] It can be understood that the elastic body 33 will generate an elastic restoring force when being compressed by the abutment body 32. The elastic restoring force can apply a force to the abutment body 32 away from the control body 31, so that the abutment body 32 can move in the direction away from the control body 31 when the control body 31 is not powered on, until the abutment body 32 abuts against the sound insulation member 20, thereby ensuring that when the control body 31 is switched between powered on and powered off, the abutment body 32 can reciprocate relative to the control body 31 and the sound insulation member 20 to realize the opening and closing of the ventilation channel 40 by the control member 30.

[0061] The telescopic rod 34 is connected between the control body 31 and the abutment body 32, and the elastic body 33 is sleeved on the telescopic rod 34. The telescopic rod 34 can guide the movement of the abutment body 32 and the elastic body 33 relative to the control body 31, so that the abutment body 32 and the elastic body 33 both move relative to the control body 31 in the width direction of the ventilation channel 40, thereby ensuring the stability of the movement trajectory of the abutment body 32 and the elastic body 33.

[0062] It should be noted that, in this embodiment, when the ventilation device 100 is in the open state, the control body 31 is in the energized state, the control member 30 opens the ventilation passage 40, the abutting body 32 is spaced apart from the sound insulation member 20, and the air flow A outside the vehicle 1000 can enter the inside of the vehicle 1000 through the ventilation passage 40. When the ventilation device 100 is in the closed state, the control body 31 is in the de-energized state, the control member 30 closes the ventilation passage 40, the abutting body 32 abuts against the sound insulation member 20, and the ventilation passage 40 is completely sealed and soundproofed, so that the air flow A outside the vehicle 1000 cannot enter the inside of the vehicle 1000 through the ventilation passage 40.

[0063] The vehicle 1000 not only needs to close the window 320 during parking to prevent theft, but sometimes, the vehicle 1000 also needs to close the window 320 when driving in bad weather or environment to prevent the bad environment and noise outside the vehicle 1000 from affecting the driver and passengers. The closing of the window 320 will cause the air inside and outside the vehicle 1000 to be blocked, thereby affecting the driving experience of the driver and the riding experience of the passengers. In this embodiment, the vehicle 1000 uses the above-mentioned ventilation device 100. The driver and the passenger can open the ventilation device 100 so that the vehicle 1000 can also circulate air inside and outside the vehicle 1000 through the ventilation channel 40 when the window 320 is closed, which not only solves the problem of the reduced air quality inside the vehicle 1000 caused by the closing of the window 320, but also the sound insulation 20 provided in the ventilation channel 40 can greatly reduce the noise entering the inside of the vehicle 1000 through the ventilation channel 40, thereby improving the driving experience of the driver and the riding experience of the passengers.

[0064] See also Figure 5 and Figure 6 , Figure 5 for Figure 1 A schematic cross-sectional view of a second embodiment of a ventilation device for a vehicle in a closed state is shown. Figure 6 for Figure 5 The cross-sectional structure diagram of the ventilation device shown is in the open state.

[0065] The structure of the ventilation device 100 in this embodiment is different from that of the ventilation device 100 in the first embodiment in that the cross section of the ventilation passage 40 in this embodiment is in the shape of a rectangular arch, and the structure of the control member 30 in this embodiment is different from that of the control member 30 in the first embodiment. In this embodiment, the control member 30 is located outside the ventilation passage 40, between the frame 10 and the top side edge 325 of the window edging 322, and is slidably connected to the frame 10. In other possible embodiments, when the window 320 is a borderless window, the control member 30 is located between the frame 10 and the top side edge 325 of the window 320, and is slidably connected to the frame 10.

[0066] In this embodiment, the control member 30 includes a control valve 36 and a sliding body 37. The control valve 36 is connected to the frame 10 and is electrically connected to the processor. The sliding body 37 is connected to the control valve 36.

[0067] The control valve 36 includes a first surface 361 and a second surface 362, which are arranged opposite to each other along the thickness direction (the X-axis direction in the figure) of the control valve 36. The first surface 361 faces the sliding body 37, and the second surface 362 faces away from the sliding body 37. In this embodiment, there is only one control valve 36, which can be an iron sheet.

[0068] It should be noted that the control valve 36 is at least partially located in the first vent 402 or the second vent 403. In this embodiment, the control valve 36 is at least partially located in the first vent 402, and can move relative to the frame 10 in the first vent 402, and can drive the sliding body 37 to move relative to the frame 10, so as to realize the opening and closing of the ventilation channel 40 by the control member 30.

[0069] It can be understood that when the ventilation device 100 is switched from the closed state to the open state, the control valve 36 moves in the first ventilation port 402 along the negative direction of the X-axis, and the control valve 36 drives the sliding body 37 to slide from the outside of the vehicle 1000 to the inside of the vehicle 1000. When the ventilation device 100 is switched from the working state to the closed state, the control valve 36 drives the sliding body 37 to slide from the inside of the vehicle 1000 to the outside of the vehicle 1000 along the positive direction of the X-axis.

[0070] The sliding body 37 includes a first portion 371 and a second portion 372, wherein the second portion 372 is connected to one side of the first portion 371 in the width direction (the X-axis direction in the figure). In this embodiment, the first portion 371 faces the inner side of the vehicle 1000, and the second portion 372 faces the outer side of the vehicle 1000. The sliding body 37 may be an electric slider.

[0071] The first portion 371 is provided with a third vent 35. The third vent 35 runs through two surfaces in the thickness direction (Z-axis direction in the figure) of the first portion 371. The third vent 35 is used to communicate with the first vent 402 or the second vent 403 of the ventilation passage 40 to achieve air exchange between the inside and outside of the vehicle 1000.

[0072] It should be noted that, along the X-axis direction, the width of the second portion 372 of the sliding body 37 may be greater than or equal to the width of the first vent 402 and the second vent 403 , ensuring that the sliding body 37 can close the first vent 402 or the second vent 403 .

[0073] In this embodiment, when the ventilation device 100 is in the closed state, Figure 5 , the first surface 361 of the control valve 36 abuts against the second channel inner wall 42 of the bottom plate 12, and the second surface 362 is relatively spaced from the first channel inner wall 41 of the top plate 11. In the Z-axis direction, the third vent 35 is completely staggered with the first vent 402 and the second vent 403. The second portion 372 of the sliding body 37 completely blocks the second vent 403 and the outside of the vehicle 1000, so that the air outside the vehicle 1000 cannot enter the inside of the vehicle 1000 through the ventilation channel 40.

[0074] When the ventilation device 100 is in the open state, Figure 6 , the second surface 362 of the control valve 36 abuts against the first channel inner wall 41 of the top plate 11, and the first surface 361 is relatively spaced from the second channel inner wall 42 of the bottom plate 12. In the Z-axis direction, the second portion 372 and the first vent 402 and the second vent 403 are all staggered, thereby leaving a gap for the air flow A to enter the ventilation channel 40, that is, the second vent 403 connects the outside of the vehicle 1000 and the main ventilation channel 401, the first vent 402 connects the main ventilation channel 401 and the third vent 35, and the third vent 35 connects the first vent 402 and the inside of the vehicle 1000, so that the air flow A outside the vehicle 1000 enters the ventilation channel 40 through the second vent 403, and enters the inside of the vehicle 1000 through the third vent 35 and the first vent 402, so that the air inside the vehicle 1000 and the air outside the vehicle 1000 can circulate.

[0075] It should be noted that when the third vent 35 is opposite to and connected to the first vent 402 in the Z-axis direction, the orthographic projection of the third vent 35 in the Z-axis direction at least partially overlaps with the orthographic projection of the first vent 402 in the Z-axis direction, thereby providing a gap for the air flow A entering the ventilation channel 40 to enter the inside of the vehicle 1000.

[0076] The assembly relationship and effects of other structural parts in this embodiment are the same as those of other structural parts in the first embodiment, and are not described in detail here.

[0077] See also Figure 7 and Figure 8 , Figure 7 for Figure 1 A schematic structural diagram of a third embodiment of a ventilation device of a vehicle in a closed state is shown. Figure 8 for Figure 7 The ventilation device shown is a simplified structural diagram in the open state.

[0078] The positional relationship between the first portion 371 and the second portion 372 of the sliding body 37 in this embodiment is different from the positional relationship between the first portion 371 and the second portion 372 in the second embodiment described above. The first portion 371 of the sliding body 37 in this embodiment faces the outside of the vehicle 1000, and the second portion 372 faces the inside of the vehicle 1000. In this embodiment, the control valve 36 is at least partially located in the second vent 403 and can move relative to the frame 10 in the second vent 403.

[0079] It can be understood that when the ventilation device 100 is switched from the closed state to the open state, the control valve 36 moves in the second ventilation port 403 along the positive direction of the X-axis, and the control valve 36 drives the sliding body 37 to move from the inside of the vehicle 1000 to the outside of the vehicle 1000. When the ventilation device 100 is switched from the working state to the closed state, the control valve 36 drives the sliding body 37 to move from the outside of the vehicle 1000 to the inside of the vehicle 1000 along the negative direction of the X-axis.

[0080] In this embodiment, when the ventilation device 100 is in a closed state, the control valve 36 abuts against the bottom plate 12 and is spaced apart from the top plate 11. The third vent 35 is completely offset from the first vent 402 and the second vent 403 in the Z-axis direction. The second portion 372 of the sliding body 37 completely blocks the first vent 402 and the inside of the vehicle 1000, so that the air flow A outside the vehicle 1000 cannot enter the inside of the vehicle 1000 through the ventilation passage 40.

[0081] When the ventilation device 100 is in an open state, the control valve 36 abuts against the top plate 11 and is spaced apart from the bottom plate 12. The second vent 403 communicates with the main ventilation passage 401 and the outside of the vehicle 1000, and the third vent 35 communicates with the second vent 403 and the outside of the vehicle 1000, so that the air flow A outside the vehicle 1000 enters the ventilation passage 40 through the third vent 35 and the second vent 403, and the air flow A then enters the inside of the vehicle 1000 through the first vent 402, so that the inside air of the vehicle 1000 circulates with the outside air.

[0082] It should be noted that when the third vent 35 is opposite to and connected to the second vent 403 in the Z-axis direction, the orthographic projection of the third vent 35 in the Z-axis direction at least partially overlaps with the orthographic projection of the second vent 403 in the Z-axis direction, thereby providing a gap for the air flow A entering the ventilation channel 40 to enter the ventilation channel 40.

[0083] The assembly relationship and effects of other structural parts in this embodiment are the same as those of other structural parts in the first embodiment, and are not described in detail here.

[0084] In the embodiment of the present application, the vehicle 1000 is provided with the ventilation device 100 described herein. Therefore, when the vehicle 1000 is driving or parking, even when the window 320 is closed, the passenger or driver can also open the ventilation device 100, that is, open the control part 30 through the processor to open the ventilation channel 40, so that the inside and outside of the vehicle 1000 can also be ventilated through the ventilation channel 40, thereby improving the quality of the air inside the vehicle 1000. At the same time, the noise entering the inside of the vehicle 1000 through the ventilation channel 40 is greatly reduced by the sound insulation 20 in the ventilation channel 40, thereby improving the driving experience of the driver and the riding experience of the passengers. In addition, the application of the ventilation device 100 described herein can reduce the frequency and time of use of the vehicle 1000 for the vehicle air conditioner, save energy consumption, and further promote green travel.
