[0053] The present invention proposes a defrosting system.

[0054] Refer to Figures 1 to 3 ,Figure 1 Partial structural schematic diagram of an embodiment of the vehicle of the present invention Figure 1 , Figure 2 Partial structural schematic diagram of an embodiment of the vehicle of the present invention Figure 2 , Figure 3 is Figure 2 The partial enlarged view of the position A in

[0055] In an embodiment of the present invention, the defrosting system is applied to a vehicle. There are two front pillars 600 on one side of the vehicle, and a front pillar triangular window is provided between the two front pillars 600. The defrosting system includes:

[0056] The first air duct structure 100 has a first air duct and a first air outlet 411 communicating with the first air duct. The first air outlet 411 faces the front pillar triangular window; and

[0057] The second air duct structure 200 has a second air duct and a second air outlet 221 communicating with the second air duct. The second air duct is communicated with the first air duct, and the second air outlet 221 faces the vehicle window of the vehicle.

[0058] The vehicle in one technical solution of the embodiment of the present invention has a double front pillar 600 structure, that is, there are two front pillars 600 on each of the left and right sides of the vehicle, and a front pillar triangular window is provided between the two front pillars 600 on each side, reducing the visual blind area of the user at the front pillar 600 and being beneficial to improving driving safety. In rainy, snowy and cold weather conditions, the front pillar triangular window is also prone to frost and fog. The present defrosting system includes a first air duct structure 100 and a second air duct structure 200. The first air duct structure 100 has a first air duct and a first air outlet 411, and the second air duct has a second air duct and a second air outlet 221. The first air duct and the second air duct are communicated, and the air flow can enter the first air duct and the second air duct simultaneously. The air flow entering the first air duct blows towards the front pillar triangular window through the first air outlet 411, thereby removing the frost and fog on the front pillar triangular window. The air flow entering the second air duct blows towards the vehicle window through the second air outlet 221, thereby removing the frost and fog on the vehicle window, thereby improving the visual permeability of the front pillar triangular window and the vehicle window, and further improving driving safety. Through the present defrosting system, the vehicle window can be defrosted and the front pillar triangular window can also be defrosted, avoiding the setting of multiple defrosting systems, thereby reducing the number of vehicle parts, improving the vehicle assembly efficiency and reducing the vehicle manufacturing cost.

[0059] Optionally, the vehicle includes a first instrument panel 400. The first air duct structure 100 includes a housing assembly 110. The housing assembly 110 and the first instrument panel 400 are buckled to form the first air duct, and the first air outlet 411 is provided on the first instrument panel 400.

[0060] Combined with Figure 1 , Figure 3 and Figure 4, in this embodiment, the vehicle includes a first instrument panel 400, a first air vent 411 is provided on the first instrument panel 400, and the first air duct structure 100 includes a housing assembly 110. The first air duct is formed by snapping the housing assembly 110 and the first instrument panel 400 together. On the one hand, the number of vehicle components is reduced, improving the assembly efficiency; on the other hand, the vehicle is lighter in weight, which is beneficial to extending the vehicle's cruising range; on the third hand, the structure under the instrument panel of the vehicle is more compact, and the vehicle has more sufficient space for arranging other components or for users to move around, thereby improving the comfort of the vehicle. The first air duct is formed by snapping the housing assembly 110 and the first instrument panel 400 together, which can be achieved by providing a groove on the housing assembly 110 and covering the groove on the housing assembly 110 with the first instrument panel 400, or by providing a groove on the first instrument panel 400 and covering the groove on the first instrument panel 400 with the housing assembly 110, or by providing grooves on both the first instrument panel 400 and the housing assembly 110 and docking the two grooves.

[0061] Optionally, the housing assembly 110 includes:

[0062] A first housing 111, provided with a first ventilation groove 1111, and the first air vent 411 is communicated with the first ventilation groove 1111; and

[0063] A second housing 112, provided with a second ventilation groove 11211, the second housing 112 is spliced with the first housing 111 and the second ventilation groove 11211 is communicated with the first ventilation groove 1111, the first instrument panel 400 covers the openings of the first ventilation groove 1111 and the second ventilation groove 11211, and the first housing 111 and the second housing 112 are respectively connected to the first instrument panel 400.

[0064] Refer to Figures 4 to 9, in this embodiment, the housing assembly 110 includes a first housing 111 and a second housing 112. A first ventilation groove 1111 is provided on the first housing 111, and a second ventilation groove 11211 is provided on the second housing 112. The second housing 112 is spliced with the first housing 111 and the second ventilation groove 11211 communicates with the first ventilation groove 1111. The first instrument panel 400 covers the openings of the first ventilation groove 1111 and the second ventilation groove 11211, and the first air outlet 411 on the first instrument panel 400 communicates with the first ventilation groove 1111, thus forming a first air duct. The air flow first enters the second ventilation groove 11211, then enters the first ventilation groove 1111 through the second ventilation groove 11211, and then flows to the front pillar triangular window through the first air outlet 411. The housing assembly 110 is provided as the first housing 111 and the second housing 112, so that the volume and weight of each housing are relatively small, which facilitates the disassembly and assembly of the first air duct structure 100. The first housing 111 and the second housing 112 are respectively connected to the first instrument panel 400, which can be realized by means of snap connection, screw connection, welding, etc. The splicing of the first housing 111 and the second housing 112 can also be realized by means of snap connection, screw connection, welding, etc. Specifically in this embodiment, a third interface 1113 is provided on the side wall of the first ventilation groove 1111. The first ventilation groove 1111 communicates with the second ventilation groove 11211 through the third interface 1113. There is a gap between the third interface 1113 and the bottom wall of the first ventilation groove 1111. When foreign objects fall into the first air duct through the first air outlet 411, the foreign objects will be stuck inside the first ventilation groove 1111, preventing the foreign objects from sliding down along the first air duct and blocking the first air duct. At the same time, it is also more convenient to remove the foreign objects, and only the first housing 111 needs to be disassembled and assembled.

[0065] Optionally, the second housing 112 includes:

[0066] A main body portion 1121, connected to the first instrument panel 400, and the main body portion 1121 is provided with a second ventilation groove 11211; and

[0067] A support portion 1122, one end of the support portion 1122 is connected to the main body portion 1121, and the other end of the support portion 1122 extends away from the main body portion 1121 to be connected to the first instrument panel 400.

[0068] Combined Figures 5 to 7, in this embodiment, the second housing 112 includes a main body portion 1121 and a support portion 1122. The second ventilation groove 11211 is provided on the main body portion 1121. The main body portion 1121 is connected to the first instrument panel 400 to form a complete air duct. One end of the support portion 1122 is connected to the main body portion 1121, and the other end of the support portion 1122 is connected to the first instrument panel 400, thereby improving the connection strength between the second housing 112 and the first instrument panel 400 and preventing the second housing 112 and the first instrument panel 400 from separating. Specifically in this embodiment, the support portion 1122 is plate-shaped, and a notch is provided on the support portion 1122. The periphery of the notch is connected to the peripheral edge of the notch of the second ventilation groove 11211 of the main body portion 1121, so that the main body portion 1121 is connected to the support portion 1122 on three sides except the side spliced with the first housing 111, thereby improving the connection strength between the main body portion 1121 and the support portion 1122; on the other hand, the plate-shaped support portion 1122 increases the connection points between the first instrument panel 400 and the support portion 1122, improving the connection strength between the support portion 1122 and the first instrument panel 400, and further reducing the possibility of the second housing 112 and the first instrument panel 400 falling off. Specifically in this embodiment, the first instrument panel 400 is the top trim panel of the vehicle instrument panel.

[0069] Optionally, the first instrument panel 400 includes:

[0070] A first sub-trim panel 410, provided with a first air vent 411, the first sub-trim panel 410 covering the first ventilation groove 1111 and being connected to the first housing 111; and

[0071] A second sub-trim panel 420, detachably connected to the first sub-trim panel 410, the second sub-trim panel 420 covering the second ventilation groove 11211 and being connected to the second housing 112.

[0072] Combined with Figure 6 and Figure 8, in this embodiment, the first instrument panel 400 includes a first sub-panel 410 and a second sub-panel 420. A first air vent 411 is provided on the first sub-panel 410. The first sub-panel 410 is connected to the first housing 111, and the second sub-panel 420 is connected to the second housing 112. The first instrument panel 400 is set as the first sub-panel 410 and the second sub-panel 420. The volume and weight of each sub-panel are relatively small, thus facilitating the disassembly and assembly of the first instrument panel 400. The first sub-panel 410 and the second sub-panel 420 can be detachably connected by means such as snap connection or screw connection. When foreign objects enter the interior of the first ventilation groove 1111 of the first housing 111, it is more convenient to remove the foreign objects by only disassembling the first sub-panel 410. Specifically, in this embodiment, a first air outlet assembly is provided on the first air vent 411. By adjusting the first air outlet assembly, the air flow direction passing through the first air vent 411 can be adjusted, so that the air flow can directly blow to different positions of the front pillar triangular window, improving the defrosting effect and efficiency, further enhancing the visual permeability of the front pillar triangular window, and further improving driving safety.

Alternatively, a first groove 1112 can be provided on the first sub-decoration plate 410, and a first protrusion 412 can be provided on the first housing 111. The first housing 111 and the first sub-decoration plate 410 are fixed by inserting the first protrusion 412 into the first groove 1112. The structure is simple, easy to manufacture, and convenient for determining the relative positions of the first housing 111 and the first sub-decoration plate 410, improving the assembly efficiency of the first housing 111 and the first sub-decoration plate 410. Specifically, in this embodiment, the first groove 1112 is provided along the peripheral edge of the notch of the first ventilation groove 1111, and the first protrusion 412 is provided on the first sub-decoration plate 410. After the first protrusion 412 is inserted into the first groove 1112, a gasket or sealant can be provided along the first protrusion 412, which not only plays a role in connecting the first housing 111 and the first sub-decoration plate 410, but also improves the sealing effect between the first housing 111 and the first sub-decoration plate 410, improves the airtightness of the first air duct, and reduces the possibility of air leakage between the first housing 111 and the first sub-decoration plate 410.

[0076] Combined with Figure 6 and Figure 7 , in this embodiment, a second groove 421 can be provided on the second housing 112, and a second protrusion 1123 corresponding to the second groove 421 can be provided on the second sub-decoration plate 420. Alternatively, a second groove 421 can be provided on the second sub-decoration plate 420, and a second protrusion 1123 can be provided on the second housing 112. The second housing 112 and the second sub-decoration plate 420 are fixed by inserting the second protrusion 1123 into the second groove 421. The structure is simple, easy to manufacture, and convenient for determining the relative positions of the second housing 112 and the second sub-decoration plate 420, improving the assembly efficiency of the second housing 112 and the second sub-decoration plate 420. Specifically, in this embodiment, the second protrusion 1123 is provided along the peripheral edge of the notch of the second ventilation groove 11211. Two ribs are provided on the second sub-decoration plate 420, and a second groove 421 is formed between the two ribs. After the second protrusion 1123 is inserted into the second groove 421, a gasket or sealant can be provided along the second protrusion 1123, which not only plays a role in connecting the second housing 112 and the second sub-decoration plate 420, but also improves the sealing effect between the second housing 112 and the second sub-decoration plate 420, improves the airtightness of the second air duct, and reduces the possibility of air leakage between the second housing 112 and the second sub-decoration plate 420.

[0077] Optionally, the second air duct structure 200 includes:

[0078] A first air duct 210, which is communicated with the first air duct; and

[0079] The second air duct 220 is provided at the vehicle door 700, and the second air outlet 221 is provided in the second air duct 220; when the door 700 is in the open state, the first air duct 210 and the second air duct 220 are disconnected; when the door 700 is in the closed state, the first air duct 210 and the second air duct 220 are communicated to divert the air flow to the vehicle door and window through the second air outlet 221.

[0080] Combined Figure 4 and Figure 12 In this embodiment, the second air duct structure 200 includes a first air duct 210 and a second air duct 220. The first air duct 210 is communicated with the first air duct, and the second air duct 220 is provided on the vehicle door 700. When the door 700 is opened, the first air duct 210 and the second air duct 220 are disconnected. When the door 700 is closed, the first air duct 210 and the second air duct 220 are communicated, and the air flow can enter the interior of the second air duct 220 through the first air duct 210, and then blow to the vehicle door and window through the second air outlet 221, so as to remove the frost and fog on the vehicle door and window. When the door 700 is opened, the interior space of the vehicle is communicated with the external space, and there will be no frost and fog on the vehicle door and window. Even if there is frost and fog on the vehicle door and window, it can be eliminated by itself at this time, and it is not necessary to use the defrosting system to remove it, reducing energy consumption. Since the door 700 itself will open and close, it is difficult to directly extend the second air duct structure 200 to the vehicle door and window, and the structure is complex. However, setting the second air duct 220 to be communicated or disconnected with the first air duct 210 as the door 700 opens and closes can reduce the manufacturing difficulty of the second air duct structure 200, improve the production efficiency of the vehicle, and reduce the manufacturing cost of the vehicle. Specifically in this embodiment, a second air outlet assembly is provided on the door trim panel of the door 700, and the air flow blown out by the second air outlet 221 blows to the vehicle door and window through the second air outlet assembly. By adjusting the second air outlet assembly, the air flow direction passing through the second air outlet 221 can be adjusted, so that the air flow can directly blow to different positions of the vehicle door and window, improving the defrosting effect and efficiency, further improving the vision permeability of the vehicle door and window, and further improving the driving safety.

[0081] Optionally, the first air duct 210 is provided with a first interface 2111 and a second interface 501. The first air duct 210 is communicated with the first air duct through the first interface 2111, and the first air duct 210 is connected to the second air duct 220 through the second interface 501. The second interface 501 is provided on the side of the first interface 2111 close to the ground; and / or,

[0082] The vehicle includes a second instrument trim panel 500. The first air duct 210 includes a third housing 211. The third housing 211 and the second instrument trim panel 500 are buckled to form a cavity, and the cavity is communicated with the first air duct and the second air duct 220.

[0083] Combined Figure 10 and Figure 11, in this embodiment, the first air duct 210 is provided with a first interface 2111 and a second interface 501. The first interface 2111 is communicated with the first air duct, and the second interface 501 is communicated with the second air duct 220. Specifically, in this embodiment, the first air duct 210 is connected to the third air duct 310 through the first interface 2111. The second interface 501 is arranged on the side of the first interface 2111 close to the ground. When a foreign object falls into the second air duct through the second air outlet 221, the foreign object will get stuck near the second interface 501. Specifically, in this embodiment, a grille is also provided at the second interface 501, and a grille is also provided at the mating interface of the second air duct 220 and the second interface 501, so as to block the foreign object inside the second air duct 220 and prevent the foreign object from entering the first air duct 210, that is, to prevent the foreign object from entering under the instrument panel of the vehicle. Blocking the foreign object inside the door makes it more convenient to remove the foreign object. Only the door trim panel and the second air duct 220 need to be disassembled and assembled.

[0084] Refer to Figure 10 , in this embodiment, the vehicle further includes a second instrument trim panel 500. The first air duct 210 includes a third housing 211. The second instrument trim panel 500 and the third housing 211 are joined together to form a cavity, thus forming the first air duct 210. On the one hand, it reduces the number of vehicle parts and improves the assembly efficiency; on the other hand, it makes the vehicle lighter in weight, which is beneficial to extending the vehicle's cruising range; on the other hand, it makes the structure under the instrument panel of the vehicle more compact, and the vehicle has more sufficient space to set other parts or for users to move, thereby improving the comfort of the vehicle. The third housing 211 and the second instrument trim panel 500 are buckled to form a cavity, which can be realized by setting a groove on the third housing 211 and covering the second instrument trim panel 500 on the groove on the third housing 211, or by setting a groove on the second instrument trim panel 500 and covering the third housing 211 on the groove on the second instrument trim panel 500, or by setting grooves on both the second instrument trim panel 500 and the third housing 211 and docking the two grooves. When the third housing 211 and the second instrument trim panel 500 are connected, a third groove can be set on the third housing 211 and a third protrusion corresponding to the third groove can be set on the second instrument trim panel 500, or a third groove can be set on the second instrument trim panel 500 and a third protrusion can be set on the third housing 211. The third housing 211 and the second instrument trim panel 500 are fixed by inserting the third protrusion into the third groove. The structure is simple, easy to manufacture, and convenient to determine the relative positions of the third housing 211 and the second instrument trim panel 500, thereby improving the assembly efficiency of the third housing 211 and the second instrument trim panel 500. Specifically, in this embodiment, the second instrument trim panel 500 is the side trim panel of the vehicle's instrument panel.

[0085] Optionally, the defrosting system further includes an air duct assembly 300. One end of the air duct assembly 300 is used to connect to the air conditioning device of the vehicle, and the other end of the air duct assembly 300 communicates with the first air duct and the second air duct.

[0086] Referring to Figure 4 , in this embodiment, the defrosting system further includes an air duct assembly 300. One end of the air duct assembly 300 is connected to the air conditioning device of the vehicle, and the other end of the air duct assembly 300 communicates with the first air duct and the second air duct. The air conditioning device generates an air flow that enters the air duct assembly 300, and then the air flow enters the first air duct and the second air duct through the air duct assembly 300 respectively, thereby realizing the defrosting function for the front pillar triangular window and the vehicle door window. The structure is simple, easy to implement, and the manufacturing cost is low.

[0087] Optionally, the air duct assembly 300 includes:

[0088] A third air duct 310. One end of the third air duct 310 is used to connect to the air conditioning device of the vehicle, and the other end of the third air duct 310 communicates with the second air duct; and

[0089] A fourth air duct 320. One end of the fourth air duct 320 communicates with the third air duct 310, and the other end of the fourth air duct 320 communicates with the first air duct.

[0090] Referring to Figure 4 , in this embodiment, the air duct assembly 300 includes a third air duct 310 and a fourth air duct 320. The third air duct 310 communicates with the air conditioning device of the vehicle, and the other end of the third air duct 310 communicates with the second air duct. Specifically, the third air duct 310 is connected to the first interface 2111 of the first air duct 210. One end of the fourth air duct 320 is disposed on the third air duct 310, and the other end of the fourth air duct 320 communicates with the first air duct. Specifically in this embodiment, since the area of the front pillar triangular window is smaller than the area of the vehicle door window, the inner diameter of the fourth air duct 320 is smaller than the inner diameter of the third air duct 310, so that the air volume of the first air duct is smaller than the air volume of the second air duct, so that more air flow is used to remove the frost and fog on the vehicle door window with a larger area, and less air flow is used to remove the frost and fog on the front pillar triangular window with a smaller area. The air flow is reasonably distributed through a simple structure, avoiding wasting resources and reducing the energy consumption of the defrosting system. The fourth air duct 320 includes a horizontal section and a vertical section. The horizontal section is disposed on the third air duct 310, and the vertical section is connected to the main body portion 1121 of the second housing 112 and is disposed at the bottom of the main body portion 1121, so that the fourth air duct 320 can play a certain supporting role for the second housing 112, reducing the possibility of the second housing 112 and the second sub-trim panel 420 falling off.
