Description

Technical Field

[0001] The present application relates to the technical field of vehicle air intake structures, and in particular to a double-laminar air intake structure for an air-conditioning box and a vehicle. Background Art

[0002] In winter, traditional car air conditioners typically use PTC or heat pumps to heat the passenger compartment by collecting cold air from outside. This heating method consumes a lot of energy, and its application in new energy vehicles can significantly reduce the vehicle's range. Therefore, to reduce energy consumption, existing technologies divide the air conditioning unit's air intake duct into two channels: one for outside air and the other for inside air. A servo motor controls the opening and closing of the outside and inside air dampers to select the air intake source. Opening both dampers simultaneously allows the inside and outside air to mix, utilizing the temperature difference between inside and outside to transfer heat and reduce heating energy consumption.

[0003] However, the air intake structure provided by the existing technology has an internal and external air intake ratio of mostly 1:1 and cannot be adjusted. The heating energy consumption is still large and cannot meet the energy consumption control requirements under multiple working conditions, resulting in a poor user experience.

[0035] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0036] like Figures 1 to 3 As shown, this embodiment provides a double laminar flow air conditioning box air intake structure, including: a shell 10 and at least three damper assemblies 20, the shell 10 has an air intake cavity 11, the air intake cavity 11 defines at least three mutually isolated air intake channels 110, each air intake channel 110 has an air intake end 1101 and an air outlet end 1102, wherein the air intake end 1101 includes an inner air intake port 11011 and an outer air intake port 11012 with the same opening area, the inner air intake port 11011 is connected to the interior of the vehicle, and is used to introduce the internal air of the vehicle to achieve The internal air circulates, while the external air intake 11012 is connected to the outside of the vehicle, for introducing air outside the vehicle to achieve fresh air circulation; at least three damper assemblies 20 are respectively arranged in the at least three air intake channels 110, and have a first state and a second state that can be switched with respect to the air intake end of the air intake channel; when the damper assembly 20 is in the first state, the internal air intake 11011 is closed and the external air intake 11012 is opened; when the damper assembly 20 is in the second state, the external air intake 11012 is closed and the internal air intake 11011 is opened. In this way, each air intake channel 110 can control the transmission of internal air or external air by switching the damper state. By performing different opening and closing combination control on the opening and closing states of the at least three damper assemblies 20, the internal and external air intake ratio can be adjusted to meet the heating energy consumption requirements under multiple working conditions, thereby improving the vehicle's cruising range and effectively improving the user experience.

[0037] For example, if Figures 1 to 3As shown, in this embodiment, there are three air intake channels, namely the first air intake channel 111, the second air intake channel 112 and the third air intake channel 113, and three damper assemblies 20 are also provided, including the first damper assembly 21 provided in the first air intake channel 111, the second damper assembly 22 in the second air intake channel 112 and the third damper assembly 23 in the third air intake channel 113, with the air intake end and the air outlet end of the first air intake channel 111 as the first air intake end 1111 and the air outlet end 1112 as the first air intake end 1111 and the air outlet end 1113 ...3 The first air outlet end 1112, the air inlet end and the air outlet end of the second air inlet channel 112 are the second air inlet end 1121 and the second air outlet end 1122, the air inlet end and the air outlet end of the third air inlet channel 113 are the third air inlet end 1131 and the third air outlet end 1132; wherein, the first air inlet end 1111 includes a first internal air inlet 11111 and a first external air inlet 11112, the second air inlet end 1121 includes a second internal air inlet 11211 and a second external air inlet 11 212, the third air inlet end 1131 includes a third internal air inlet 11311 and a third external air inlet 11312; when the first damper assembly 21 is in the first state, the first internal air inlet 11111 is closed and the first external air inlet 11112 is opened; when the first damper assembly 21 is in the second state, the first external air inlet 11112 is closed and the first internal air inlet 11111 is opened; similarly, when the second damper assembly 22 is in the first state, the second internal air inlet is closed. When the second damper assembly 22 is in the second state, the second external air inlet 11212 is closed and the second internal air inlet 11211 is opened. When the third damper assembly 23 is in the first state, the third internal air inlet 11311 is closed and the third external air inlet 11312 is opened. When the third damper assembly 23 is in the second state, the third external air inlet 11312 is closed and the third internal air inlet 11311 is opened. By controlling the states of the three damper assemblies 20 in different opening and closing combinations, the ratio of internal and external air intake can be adjusted to meet heating energy consumption requirements under multiple working conditions, thereby increasing vehicle range and effectively improving the user experience.

[0038] It can also be understood that the damper assembly 20 can switch its state by rotating or translating, and the specific switching method can be set according to the setting position and direction of the internal air inlet 11011 and the external air inlet 11012. For example, in this embodiment, the damper assembly 20 is a fan-shaped blocking member and can be driven to rotate by a motor and a motor shaft, so that the internal air inlet 11011 is opened toward the upper side of the figure, and the external air inlet 11012 is opened toward the right side of the figure, and the internal air inlet 11011 and the external air inlet 11012 are corresponding to each other in the circumferential direction of the rotation axis of the damper assembly 20. In this way, when the damper assembly 20 is driven to rotate toward the internal air inlet 11011, the internal air inlet 11011 is blocked. , and open the external air inlet 11012, the damper assembly 20 is in the first state, and the external air of the vehicle can enter from the external air inlet 11012, thereby realizing external air circulation; when the damper assembly 20 is driven to rotate toward the external air inlet 11012, the external air inlet 11012 is blocked, and the internal air inlet 11011 is opened, the damper assembly 20 is in the second state, and the internal air of the vehicle can enter from the internal air inlet 11011, thereby realizing internal air circulation.

[0039] In some embodiments, as Figure 1 and Figure 2 As shown, the opening areas of the intake ends 1101 of the various intake channels 110 are different, meaning that the intake volumes of the various intake channels 110 are different, and the proportion of the intake volume of the various intake channels 110 to the total intake volume is also different. Thus, by combining the opening and closing states of different dampers, the internal and external air intake ratio can be further refined. For example, assuming that the opening area of the first intake end 1111: the opening area of the second intake end 1121: the opening area of the third intake end 1131 = 15:50:35, by combining the opening and closing states of different damper assemblies 20, the internal and external air intake ratio can be refined to 0%, 15%, 35%, 50%, 65%, 85%, and 100%. By selecting the appropriate internal and external air intake ratio based on the heating energy consumption requirements of different operating conditions, heating energy consumption can be effectively reduced, thereby increasing vehicle range and enhancing the user experience.

[0040] It can be understood that the above-mentioned air inlet end 1101 includes an internal air inlet 11011 and an external air inlet 11012, and the opening areas of the internal air inlet 11011 and the external air inlet 11012 are the same. Therefore, the opening area of the air inlet end 1101 can refer to the opening area of one of the internal air inlet 11011 and the external air inlet 11012 of the air inlet end 1101, or it can refer to the sum of the opening areas of the internal air inlet 11011 and the external air inlet 11012 of the air inlet end 1101.

[0041] In some embodiments, as Figure 1and Figure 2 As shown, the opening heights of the air inlet ends 1101 (including the internal air inlet port 11011 and the external air inlet port 11012 of the air inlet end 1101) are the same but the opening widths are different. When the opening heights of the air inlet ends 1101 remain the same, by changing the opening width of the air inlet end 1101 and thus changing the opening area of the air inlet end 1101, on the one hand, it is possible to avoid occupying the Z-direction space of the air inlet structure, and on the other hand, when the damper assembly 20 is switched to an open or closed state by rotating, it is convenient to uniformly set the rotation angle. It is understandable that when the opening and closing state of the damper assembly 20 relative to the air inlet end 1101 is changed by rotation, the circumferential direction of the rotation axis is used as the opening height direction, and the axial direction of the rotation axis is used as the opening width direction; when the opening and closing state of the damper assembly 20 relative to the air inlet end 1101 is changed by translation, the vehicle height direction is used as the opening height direction, and the vehicle width direction is used as the opening width direction.

[0042] In some embodiments, as Figures 1 to 3 As shown, the air intake channel 110 includes the above-mentioned first air intake channel 111, the second air intake channel 112 and the third air intake channel 113, wherein the sum of the opening area of the air intake end of the first air intake channel 111, i.e., the first air intake end 1111, and the opening area of the air intake end of the third air intake channel 113, i.e., the third air intake end 1131, is equal to the opening area of the air intake end of the second air intake channel 112, i.e., the second air intake end 1121. In this way, the intake volume of the intake end of the second air intake channel 112, i.e., the second air intake end 1121, can be made to account for 50%. When the internal and external air are mixed for intake, the damper assembly 20, i.e., the second damper assembly 22, in the second air intake channel 112 can always be maintained in the second state to ensure that the proportion of the internal air intake volume remains at a minimum of 50%. By switching the opening and closing states of the damper assembly of the first air intake channel 111, i.e., the first damper assembly 21 and / or the damper assembly of the third air intake channel 113, i.e., the third damper assembly 23, the proportion of the internal air intake volume can be adjusted to 50% or above, thereby achieving the purpose of further reducing heating energy consumption and improving vehicle cruising range.

[0043] For example, assuming that the opening area of the first air inlet end 1111: the opening area of the second air inlet end 1121: the opening area of the third air inlet end 1131 = 15:50:35, the double-layer air-conditioning box air-inlet structure has three mixed air-inlet modes according to the working states of the first damper assembly 21, the second damper assembly 22 and the third damper assembly 23, wherein: when the first damper assembly 21 is in the first state, the second damper assembly 22 is in the second state, and the third damper assembly 23 is in the first state, the double-layer air-conditioning box air-inlet structure is in the first mixed air-inlet mode. In the first mixed air-inlet mode, In the second state, the internal air intake accounts for 50%; when the first damper assembly 21 is in the second state, the second damper assembly 22 is in the second state, and the third damper assembly 23 is in the first state, the double-layer flow air conditioning box air intake structure is the second mixed air intake mode. In the second mixed air intake mode, the internal air intake accounts for 65%; when the first damper assembly 21 is in the first state, the second damper assembly 22 is in the second state, and the third damper assembly 23 is in the second state, the double-layer flow air conditioning box air intake structure is the third mixed air intake mode. In the third mixed air intake mode, the internal air intake accounts for 85%. In this way, the internal air intake proportion can be arranged in a gradient and refined manner, and the appropriate mixed air intake mode can be selected according to the heating energy consumption requirements of different working conditions, so as to effectively reduce heating energy consumption and improve vehicle cruising range.

[0044] Furthermore, the double-layer air-conditioning box air intake structure also has a fresh air mode and an internal circulation mode according to the working status of the first damper assembly 21, the second damper assembly 22 and the third damper assembly 23, wherein when the first damper assembly 21 is in the first state, the second damper assembly 22 is in the first state, and the third damper assembly 23 is in the first state, the double-layer air-conditioning box air intake structure is in the fresh air mode. In the fresh air mode, the internal air intake accounts for 0%, and only the external air of the vehicle is allowed to enter the air intake structure; when the first damper assembly 21 is in the second state, the second damper assembly 22 is in the second state, and the third damper assembly 23 is in the second state, the double-layer air-conditioning box air intake structure is in the internal circulation mode. In the internal circulation mode, the internal air intake accounts for 100%, and only the internal air of the vehicle is allowed to enter the air intake structure.

[0045] In some embodiments, as Figure 4As shown, the dual-laminar air conditioning box air intake structure also includes: a first drive mechanism 31 and a second drive mechanism 32. The first drive mechanism 31 is configured to drive the first damper assembly 21 and the second damper assembly 22 to switch states in the corresponding air intake channels. Driven by the first drive mechanism 31, the first damper assembly 21 and the second damper assembly 22 can move asynchronously or relatively independently. The specific drive method and control logic can refer to the existing technology and are not described here. The second drive mechanism 32 is configured to drive the third damper assembly 23 to switch states in the third air intake channel 113. Driven by the second drive mechanism 32, the third damper assembly 23 can move independently. In this way, the three damper assemblies can be driven by two drive mechanisms, reducing the need for the active drive device and effectively reducing the space occupied by the air intake structure.

[0046] For example, if Figure 4 As shown, in this embodiment, the first driving mechanism 31 can be a combination of a driving motor, a cam-link mechanism and corresponding transmission parts, the first damper assembly 21, the second damper assembly 22 and the third damper assembly 23 are coaxially arranged, and the first driving mechanism 31 is arranged near the first damper assembly 21 on the side of the housing 10, and the transmission parts of the first driving mechanism 31 extend into the housing 10 from the side of the housing 10 and are respectively connected to the first damper assembly 21 and the second damper assembly 22 to drive the first damper assembly 21 and the second damper assembly 22 to rotate asynchronously or relatively independently, so that the first damper assembly 21 and the second damper assembly 22 can ... The door assembly 21 can switch its state relative to the first air inlet end 1111, and the second air damper assembly 22 can switch its state relative to the second air inlet end 1121. The second drive mechanism 32 can be a combination of a drive motor and a drive shaft. The second drive mechanism 32 is disposed on the opposite side of the housing 10, near the third air damper assembly 23. The drive shaft of the second drive mechanism 32 extends from the opposite side of the housing 10 into the housing 10 and is in transmission connection with the third air damper assembly 23, thereby driving the third air damper assembly 23 to rotate independently, allowing the third air damper assembly 23 to switch its state relative to the third air inlet end 1131. Similarly, in other embodiments, the first drive mechanism 31 can be configured to drive the third air damper assembly 23 and the second air damper assembly 22 to switch their states in the corresponding air inlet passages, and the second drive mechanism 32 can be configured to drive the first air damper assembly 21 to switch its state in the first air inlet passage 111. The only difference from the aforementioned configuration is the driven object, while the specific drive method and control logic are the same as the aforementioned configuration and will not be repeated here.

[0047] In some embodiments, as Figures 1 to 3As shown, the shell 10 also has a guide cavity 12 inside, which is connected to the air outlet ends of multiple air inlet channels 110; a guide component 40 is provided in the guide cavity 12, and the guide cavity 12 is divided into a first air duct 121 and a second air duct 122 by the guide component 40, and the air outlet end of the second air inlet channel 112, namely the second air outlet end 1122, is connected to the second air duct 122, and the air outlet end of the first air inlet channel 111, namely the first air outlet end 1112, and the air outlet end of the third air inlet channel 113, namely the third air outlet end 1132, are connected to the first air duct 121. In this way, the introduced gas can be directionally layered through the first air duct 121 and the second air duct 122 to enhance the user experience; for example, the second air door assembly 22 is switched to the second state, and at least one of the first air door assembly 21 and the third air door assembly 23 is switched to the first state, so that the second air duct 122 provides internal circulation air intake, and the first air duct 121 provides external circulation air intake or internal and external mixed air intake; at this time, the second air duct 122 can be used as a foot blowing air duct to output the internal circulation air intake to the lower layer of the vehicle, which is beneficial to heating the entire vehicle; the first air duct 121 is used as a face blowing / defrosting air duct to blow towards the front windshield or to the upper layer of the vehicle, which can prevent the front windshield from fogging and improve the comfort of the driver and passengers.

[0048] For example, if Figure 2 and Figure 3 As shown, in this embodiment, the air inlet chamber 11 and the guide chamber 12 are distributed up and down, and the guide chamber 12 is located below the air inlet chamber 11. The guide assembly 40 includes a centrifugal fan 41, a partition 42 and a guide cover 43. The impeller 411 of the centrifugal fan 41 is axially arranged toward the air inlet chamber 11; the partition 42 is arranged on the circumferential outer side of the impeller 411 and extends to the casing 10 along the radial direction of the impeller 411, so as to separate the axial sides of the impeller 411 into a first air duct 121 and a second air duct 122 distributed up and down, and the second air duct 122 is located below the first air duct 121; the guide cover 43 is arranged inside the impeller 411, and the whole is bucket-shaped or trumpet-shaped, one end of which extends to the circumferential inner side of the impeller 411 corresponding to the partition 42, and the other end extends along the axial direction of the impeller 411 to be connected with the outlet end of the second air inlet channel 112, that is, the second air outlet end 1122. In this way, when the impeller 411 rotates, the gas in the air inlet chamber 11 enters along the axial direction of the impeller 411 and is output to the guide chamber 12 along the radial direction of the impeller 411, wherein the gas output from the first air outlet end 1112 and the third air outlet end 1132 enters the first air duct 121 along the outer wall of the guide cover 43, and the gas output from the second air outlet end 1122 enters the second air duct 122 along the inner wall of the guide cover 43, thereby realizing directional layered output of the gas, and after being guided by the above-mentioned guide component 40, the gas supply stratification effect is obvious, and it is not easy to mix, which can effectively reduce heating energy consumption and thereby improve the vehicle's cruising range.
