Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a front defrost air duct structure, an air conditioning system, and a vehicle. Background Art

[0002] In cold weather, the large temperature difference between the inside and outside of the car can cause frost on the front windshield, affecting driving safety. To prevent the interior glass from frosting, the driver needs to turn on the air conditioner to blow warm air to the interior glass. The warm air is blown to the front windshield through the front defrost duct connected to the air conditioning duct. The front defrost duct is usually located below the front end of the dashboard in the cab, and the air conditioning duct is located below the front defrost duct to blow warm air to the front defrost duct. The front defrost duct and the air conditioning duct are usually connected by a buckle and a snap-on hole. During installation, the buckle needs to be deformed to pass through the snap-on hole. When the front defrost duct needs to be replaced or cleaned and needs to be disassembled, the buckle also needs to be deformed to be disengaged from the snap-on hole. Multiple deformations can easily cause the buckle to fail, making the connection unstable, thereby affecting the defrosting effect. Summary of the Invention

[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] The front defrost duct structure, air conditioning system and vehicle disclosed herein are described in detail below through specific embodiments:

[0042] Reference Figures 1 to 7 As shown, an embodiment of the present invention provides a front defrost duct structure, an air-conditioning system and a vehicle, including a defrost duct 1 and an air-conditioning duct 2, and the air inlet end of the defrost duct 1 is connected to the air outlet end of the air-conditioning duct 2, so that the defrost duct 1 and the air-conditioning duct 2 are connected, and the air-conditioning duct 2 can be connected to the air conditioner and blow warm air toward the front windshield through the air conditioner. A hook 11 is provided on one of the defrost duct 1 and the air-conditioning duct 2, and an insertion gap 113 is formed between one of the defrost duct 1 and the air-conditioning duct 2 and the hook 11, and a card plate 21 is provided on the other of the defrost duct 1 and the air-conditioning duct 2, and the card plate 21 extends in a direction parallel to the air inlet end of the defrost duct 1 or the air outlet end of the air-conditioning duct 2, so that the card plate 21 forms a plate-like structure, and the card plate 21 is inserted in the insertion gap 113, so that the defrost duct 1 and the air-conditioning duct 2 are plugged into the card plate 21 through the hook 11.

[0043] Among them, the insertion gap 113 is extended in a direction parallel to the air inlet end of the defrost duct 1 or the air outlet end of the air-conditioning duct 2, and the card plate 21 is extended in a direction parallel to the air inlet end of the defrost duct 1 or the air outlet end of the air-conditioning duct 2, that is, the extension direction of the card plate 21 is adapted to the extension direction of the insertion gap 113, so that the card plate 21 can be inserted into the insertion gap 113 in a direction parallel to the air inlet end of the defrost duct 1 or the air outlet end of the air-conditioning duct 2, thereby realizing the plug-in fit between the hook 11 and the card plate 21.

[0044] That is to say, during assembly, the defrost duct 1 and the air-conditioning duct 2 can be connected together by directly plugging the hook 11 and the card plate 21 into the insertion gap 113, which is convenient for installation. When disassembling the defrost duct 1, the card plate 21 can be directly pulled out from the insertion gap 113 to complete the disassembly. Compared with the installation method using buckles and snap holes, the hook 11 and the card plate 21 can complete the installation and disassembly between the defrost duct 1 and the air-conditioning duct 2 without deformation, and the operation is simple and the connection is stable.

[0045] It can be understood that the hook 11 is arranged on one of the defrost duct 1 and the air-conditioning duct 2, and protrudes toward the other of the defrost duct 1 and the air-conditioning duct 2, and an insertion gap 113 is formed between one of the defrost duct 1 and the air-conditioning duct 2 and the hook 11, and the card plate 21 on the other of the defrost duct 1 and the air-conditioning duct 2 can be inserted into the insertion gap 113, thereby realizing the connection and limitation between the defrost duct 1 and the air-conditioning duct 2.

[0046] In specific implementation, the air-conditioning duct 2 is connected to the air conditioner, and the defrost duct 1 is installed between the air-conditioning duct 2 and the front dashboard of the vehicle under the front windshield, and the connection and limitation between the defrost duct 1 and the air-conditioning duct 2 are realized by the plug-in cooperation between the hook 11 and the card plate 21. Furthermore, the defrost duct 1 can be fixed to the front dashboard of the vehicle by fasteners such as screws and bolts, and then the defrost duct 1 is fixed between the air-conditioning duct 2 and the front dashboard to prevent the defrost duct 1 from falling out. With such a setting, the air conditioner can achieve stable air outlet to the front windshield, thereby ensuring the defrosting effect of the front windshield.

[0047] When implementing it, refer to Figure 5 and Figure 6 As shown, the hook 11 is arranged at the air inlet end of the defrost duct 1, and the clamping plate 21 is arranged at the air outlet end of the air conditioning duct 2. Specifically, the hook 11 includes a first folded edge 111 and a second folded edge 112 connected to each other. The first folded edge 111 is extended from the air inlet end of the defrost duct 1 toward the air conditioning duct 2, that is, the first folded edge 111 protrudes from the surface of the air inlet end of the defrost duct 1, and the second folded edge 112 is connected to the first folded edge 111 and extends in a direction parallel to the air inlet end of the defrost duct 1, so that the insertion gap 113 formed between the second folded edge 112 and the surface of the air inlet end of the defrost duct 1 extends in a direction parallel to the air inlet end of the defrost duct 1. Figure 6 As shown, the first folded edge 111 and the second folded edge 112 are arranged at an angle so that the hook 11 is in an L-shaped structure, and an insertion gap 113 is formed between the second folded edge 112 and the air inlet end of the defrost duct 1 .

[0048] Reference Figure 7 As shown, the clamping plate 21 is a plate-like structure formed on the air outlet end of the air conditioning duct 2. It is understood that an insertion entrance of an insertion gap 113 is formed between the end of the second folded edge 112 away from the first folded edge 111 and the air inlet end of the defrost duct 1, so that the clamping plate 21 can be inserted into the insertion gap 113 through the insertion entrance, thereby achieving the connection between the defrost duct 1 and the air conditioning duct 2.

[0049] It is understandable that when the clamping plate 21 is inserted into the insertion gap 113, the clamping plate 21 can abut against the end face of the air inlet end of the defrost duct 1, thereby abutting the clamping plate 21 between the air inlet end of the defrost duct 1 and the second folded edge 112, thereby achieving the connection between the defrost duct 1 and the air conditioning duct 2. Of course, it is also possible to form a protrusion on the end face of the air inlet end of the defrost duct 1 in the direction toward the air conditioning duct 2, and form a clamping surface on the protruding surface, thereby causing the clamping plate 21 to abut and be limited between the second folded edge 112 and the clamping surface, thereby increasing the clamping strength between the hook 11 and the clamping plate 21.

[0050] Of course, it should be noted that the hook 11 and the card plate 21 can also be other forms of structures, and the present disclosure does not limit this. As long as an insertion gap 113 can be formed between the hook 11 and the defrost duct 1 or the air-conditioning duct 2 and the card plate 21 can be inserted into the insertion gap 113 to complete the connection between the defrost duct 1 and the air-conditioning duct 2, it will be sufficient.

[0051] In some embodiments, reference Figure 6 As shown, a guide portion 114 is provided at one end of the second folded edge 112 away from the first folded edge 111. The surface of the guide portion 114 facing the defrost duct 1 is formed into a guide slope. In the direction from the guide portion 114 to the first folded edge 111, the guide slope extends obliquely toward the defrost duct 1. With this arrangement, the clip 21 can be inserted into the insertion gap 113 along the guide slope from the guide portion 114 to the first folded edge 111, making installation convenient and simple.

[0052] Continue to refer to Figure 6 As shown, reinforcing ribs 115 are provided on the first folded edge 111 and the second folded edge 112 to enhance the structural strength of the hook 11, thereby ensuring the connection strength between the defrost duct 1 and the air conditioning duct 2. At least some of the reinforcing ribs 115 are located on the side of the second folded edge 112 close to the air inlet end of the defrost duct 1, and at least some of the ends of the reinforcing ribs 115 form a rounded transition. That is, the ends of the reinforcing ribs 115 located on the side of the second folded edge 112 close to the air inlet end of the defrost duct 1 form a rounded transition, which facilitates the insertion of the clamping plate 21 into the insertion gap 113 formed between the hook 11 and the air inlet end of the defrost duct 1 along the rounded transition.

[0053] Furthermore, the reinforcing rib 115 can extend from the first folded edge 111 and the second folded edge 112 to the side surface of the defrost duct 1 away from the air-conditioning duct 2. The present disclosure does not limit this and can be specifically set according to actual needs.

[0054] It can be understood that there are multiple reinforcing ribs 115, and the multiple reinforcing ribs 115 are arranged at intervals on the first fold edge 111 and the second fold edge 112, and the ends of the multiple reinforcing ribs 115 located on the side of the second fold edge 112 close to the air inlet end of the defrost duct 1 can form a rounded transition to facilitate the snap-fit ​​between the hook 11 and the card plate 21.

[0055] In some embodiments, reference Figure 5 As shown, a first air guide channel 12 is formed inside the defrost duct 1 and extends axially along the defrost duct 1. That is, the wind from the air-conditioning duct 2 enters the first air guide channel 12 through the air inlet end of the defrost duct 1, and is then blown out toward the front windshield through the first air guide channel 12.

[0056] Reference Figure 7As shown, a second air guide channel 22 is formed inside the air conditioning duct 2 and extends along the axial direction of the air conditioning duct 2. The second air guide channel 22 is connected to the first air guide channel 12. That is, air from the air conditioner can enter the second air guide channel 22 and be blown out of the air outlet of the air conditioning duct 2 toward the defrost duct 1 through the second air guide channel 22. It can be understood that the warm air blown out of the air conditioner passes through the second air guide channel 22 and the first air guide channel 12 in sequence and is blown toward the front windshield to achieve the defrosting function of the front windshield.

[0057] Specifically, the hook 11 is staggered with the end of the first air guide channel 12 near the air conditioning duct 2, that is, the hook 11 is disposed at the air inlet end of the defrost duct 1, avoiding the first air guide channel 12. The clamping plate 21 is staggered with the end of the second air guide channel 22 near the defrost duct 1, that is, the clamping plate 21 is disposed at the air outlet end of the air conditioning duct 2, avoiding the second air guide channel 22. It is understandable that the positions of the hook 11 and the clamping plate 21 correspond to each other, so that the connection between the defrost duct 1 and the air conditioning duct 2 is achieved through the plug-in cooperation between the hook 11 and the clamping plate 21.

[0058] It should be noted that the hook 11 can also be set on the air outlet end of the air conditioning duct 2, and the card plate 21 is set on the air inlet end of the defrost duct 1. This disclosure does not limit this and can be specifically set according to actual needs.

[0059] When implementing it, continue to refer to Figure 5 As shown, there are two first air guide channels 12, and both first air guide channels 12 are connected to the air inlet end of the defrost duct 1, that is, the two first air guide channels 12 are arranged in parallel, and both take in air through the air inlet end of the defrost duct 1, and the hook 11 is arranged on the air inlet end of the defrost duct 1 between the two first air guide channels 12.

[0060] Further, continue to refer to Figure 7 As shown, there are two second air guide channels 22, and both second air guide channels 22 are connected to the air outlet end of the air-conditioning duct 2, that is, the two second air guide channels 22 are arranged in parallel, and both discharge air through the air outlet end of the air-conditioning duct 2. The two second air guide channels 22 are arranged in a one-to-one correspondence with the two first air guide channels 12 and are connected. The card plate 21 is arranged on the air outlet end of the air-conditioning duct 2 between the two second air guide channels 22, and is arranged corresponding to the card hook 11.

[0061] It is understood that the hook 11 and the card plate 21 are correspondingly arranged, enabling the hook 11 and the card plate 21 to be engaged, and when the hook 11 and the card plate 21 are engaged, the two first air guide channels 12 are arranged in a one-to-one correspondence with and connected to the two second air guide channels 22, thereby blowing warm air toward the front windshield. In a specific implementation, the hook 11 is arranged between the two first air guide channels 12, and the card plate 21 is arranged between the two second air guide channels 22. The end of the first air guide channel 12 away from the second air guide channel 22 covers the bottom of the front windshield to ensure the defrosting effect of the front windshield. Furthermore, the end of the second air guide channel 22 away from the first air guide channel 12 covers the air conditioning outlet, thereby completely blowing the air blown out by the air conditioner toward the front windshield to prevent wind damage.

[0062] Of course, it should be noted that the number of the first air guide channel 12 and the second air guide channel 22 can also be three, four or more, and the present disclosure does not limit this, as long as the number of the first air guide channel 12 and the second air guide channel 22 is the same and can blow the warm air blown out of the air conditioner onto the front windshield one by one.

[0063] It should be noted that the hook 11 can also be set at other positions on the air inlet end of the defrost duct 1, and the card plate 21 can also be set at other positions on the air outlet end of the air-conditioning duct 2. The present disclosure does not limit this, as long as the hook 11 and the card plate 21 are set correspondingly and can be plugged into and matched with each other to realize the connection between the defrost duct 1 and the air-conditioning duct 2.

[0064] In some embodiments, reference Figure 3 As shown, the air inlet end of the defrost duct 1 forms a first mating surface 13, and the air outlet end of the air-conditioning duct 2 forms a second mating surface 23. The first mating surface 13 and the second mating surface 23 abut against each other to prevent the wind force of the warm air blown out by the air conditioner from being damaged and to ensure the defrosting effect.

[0065] Furthermore, the first mating surface 13 and the second mating surface 23 are formed as inclined surfaces with the same slope, and the retaining plate 21 is inserted into the insertion gap 113 in a direction parallel to the inclined surfaces. It will be appreciated that due to the limited space within the vehicle, the first mating surface 13 and the second mating surface 23 are formed as inclined surfaces. This allows the defrost duct 1 to be inserted between the air conditioning duct 2 and the vehicle's front dashboard below the front windshield in a direction parallel to the first mating surface 13 and the second mating surface 23, resulting in simple operation and convenient installation.

[0066] In a specific implementation, the insertion gap 113 extends in a direction parallel to the inclined surface, and gradually slopes downward along the direction from the air conditioning duct 2 to the defrost duct 1. The clamping plate 21 extends in a direction parallel to the inclined surface, and gradually slopes downward along the direction from the air conditioning duct 2 to the defrost duct 1. In this configuration, the insertion gap 113 and the clamping plate 21 are adapted to achieve plug-in fit.

[0067] That is to say, the second folded edge 112 of the hook 11 extends in a direction parallel to the inclined surface, so that an insertion gap 113 extending in a direction parallel to the inclined surface is formed between the second folded edge 112 and the inclined surface, thereby enabling the card plate 21 to be inserted between the second folded edge 112 and the first mating surface 13 or the second mating surface 23.

[0068] Furthermore, an opening is formed on the side of the insertion gap 113 away from the air conditioning duct 2, that is, the opening is arranged in an obliquely downward direction. This arrangement allows the clamping plate 21 to be inserted into the insertion gap 113 through the opening when the defrost duct 1 is installed. It can be understood that when the clamping plate 21 is inserted into the insertion gap 113, the hook 11 can abut against the clamping plate 21, thereby absorbing part of the weight of the defrost duct 1. In other words, when the clamping plate 21 is inserted into the insertion gap 113, the second folded edge 112 can abut against the bottom of the clamping plate 21, thereby absorbing the weight.

[0069] Of course, it should be noted that the insertion gap 113 and the card plate 21 can also be extended in other directions, and the present disclosure does not limit this. Specifically, it can be set according to the actual installation space in the vehicle, as long as the card plate 21 can be conveniently inserted into the insertion gap 113 to achieve the connection between the defrost duct 1 and the air-conditioning duct 2.

[0070] In some embodiments, reference Figure 4 As shown, a sponge sealing strip 3 is provided on one of the first mating surface 13 and the second mating surface 23 to improve the sealing performance between the defrost duct 1 and the air conditioning duct 2, thereby enhancing defrosting efficiency. In a specific implementation, the sponge sealing strip 3 is adhered to the first mating surface 13 or the second mating surface 23. This arrangement allows the sponge sealing strip 3 to be pressed between the defrost duct 1 and the air conditioning duct 2, ensuring a good seal between the two. Specifically, the sponge sealing strip 3 can be adhered using double-sided tape.

[0071] It should be noted that the inlet of the first air guide channel 12 is formed on the first mating surface 13, and the outlet of the second air guide channel 22 is formed on the second mating surface 23. The sponge sealing strip 3 is attached to the first mating surface 13 at a position avoiding the first air guide channel 12 or is attached to the second mating surface 23 at a position avoiding the second air guide channel 22, so as to ensure the sealing performance while ensuring smooth ventilation between the first air guide channel 12 and the second air guide channel 22 to ensure the defrosting effect.

[0072] Of course, it should be noted that other sealing structures can be set between the first mating surface 13 and the second mating surface 23. The present disclosure does not limit this, as long as it can be set between the defrost duct 1 and the air-conditioning duct 2 and the sealing performance between the defrost duct 1 and the air-conditioning duct 2 is guaranteed.

[0073] It can be understood that the hook 11 and one of the card plates 21, the defrost duct 1 and the first air guide channel 12 are an integral blow-molded structure, and the hook 11 and the other of the card plates 21, the air-conditioning duct 2 and the second air guide channel 22 are an integral blow-molded structure, which is low in cost.

[0074] The present disclosure also provides an air-conditioning system, including a front defrost duct structure as in any of the above embodiments, for blowing air toward the front windshield for defrosting, and also for blowing air toward the passenger's face or feet, etc., to increase or decrease the temperature in the vehicle cabin and enhance the user experience.

[0075] The air-conditioning system provided by the embodiment of the present disclosure includes the front defrost duct structure of any of the above embodiments, and thus has the beneficial effects of the front defrost duct structure of any of the above embodiments, which will not be described in detail here.

[0076] Other embodiments of the present disclosure provide a vehicle including the air conditioning system according to the above embodiments.

[0077] The vehicle provided by the embodiment of the present disclosure includes the air-conditioning system of the above embodiment, and thus has the beneficial effects of the air-conditioning system of the above embodiment, which will not be described in detail here.
