Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle defrosting, and particularly relates to an adjustable defrost air duct system for an automobile and a vehicle. Background Technique

[0002] In winter or rainy and snowy weather, due to the decrease in outdoor temperature, the front windshield of an automobile is prone to frosting, which will make the driving vision blurred. The driver cannot see the road outside the window clearly, and it is easy to cause potential safety hazards.

[0003] The traditional method is to adjust the air-conditioning button to make the air in the blower blow towards the defrost air duct. The partition of the defrost air duct guides the air, so that the warm air blows towards the front windshield to achieve defrosting. Since the partition is fixed, the air has directivity and fixity. Therefore, when the fog and frost are dispersed by the wind, it can only be achieved through the accumulation of time and gradually spread from the local area to the surrounding area to achieve comprehensive defrosting. In order to avoid the above situation, it is required that the designers allocate the air volume in advance at the beginning of the design, so that the air spreads out. However, the result of this is that the air volume is dispersed and not concentrated, resulting in a waste of defrosting time, and it cannot be accurately spread to the effective area, resulting in a limited defrosting coverage area of the front windshield of the automobile and a reduction in defrosting efficiency. Moreover, the frosting area may only cover a small part of the front windshield. If there is frosting only in a certain area, since the partition is fixed and the wind direction is fixed, only a part of the wind force is directly blown towards the frosting area, while the other part of the wind force is dispersed to the non-frosting area, and the wind force cannot be concentrated to blow towards the frosting area in the front windshield, resulting in a waste of energy and a reduction in defrosting efficiency.

[0017] A groove is provided in the protruding portion, and the connecting member has a convex rod adapted to the groove. The convex rod is connected to the groove so that the connecting member is connected to the guiding member.

[0018] A positioning portion for clamping with the connecting member is formed on one side of the convex portion; the driving mechanism drives the guiding member to move, and drives the connecting member to swing relative to the air duct body through the positioning portion.

[0019] This application also relates to a vehicle, which is based on the above-mentioned adjustable defrost air duct system for an automobile.

[0020] Due to the adoption of the above technical solutions, the beneficial effects achieved by the present utility model are as follows:

[0021] 1. An adjustable defrost air duct system for an automobile, including an air duct body having an air inlet and an air outlet arranged opposite to each other; a transmission device is connected to the outer side of the air duct body near the air inlet; the transmission device includes a driving mechanism connected to the air duct body, a guiding member connected to the driving mechanism, and a connecting member connected to the guiding member; the blade assembly has a plurality of air guiding blades connected to the inside of the air duct body corresponding to the air outlet, and the air guiding blades have connecting portions extending outside the air duct body and vertically connected to the connecting member; by driving the guiding member to move along the air duct body through the driving mechanism, the connecting member is driven to rotate, so that the air guiding blades swing relative to the air duct body to adjust the air direction of the air outlet.

[0022] The air flow enters the air duct body through the air inlet of the air duct body, passes through the blade assembly to adjust the air direction, and then is sent out from the air outlet, so as to blow different areas of the front windshield to achieve defrosting, avoiding the traditional defrosting method that can only spread gradually from a local area to the surrounding area. The blade assembly of this application includes a plurality of air guiding blades that swing relative to the air duct body, and the air flow flows out between the air guiding blades to realize the adjustment of the air direction. Different from the traditional fixed-direction air, the air direction can be freely adjusted, and effective targeted defrosting can be carried out according to different frosting areas on the front windshield, avoiding the waste of wind force, concentrating the wind force for defrosting operations in the frosting area, and improving the defrosting efficiency.

[0023] 2. As a preferred embodiment of the present utility model, the driving mechanism has a fixed portion connected to the air duct body and a rotating portion that rotates relative to the air duct body; the first positioning end of the guiding member cooperates with the rotating portion, and the guiding member is driven to move relative to the air duct body by the rotation of the rotating portion. The second positioning end of the guiding member is connected to the connecting member, and the connecting member is driven to swing a preset angle relative to the air duct body by the movement of the guiding member.

[0024] As a device that provides driving force, the driving mechanism drives the guiding member to linearly move relative to the air duct body during the rotation of its rotating part relative to the air duct body, realizing the conversion of the rotational motion of the driving mechanism into the linear motion of the guiding member. During the linear motion of the guiding member, it can drive the connecting member to swing relative to the air duct body. Since the connecting part of the connecting member and the air guiding blade is vertically connected and the connecting member is connected to the second positioning end of the guiding member, the linear movement of the guiding member drives the connecting member and the air guiding blade to swing relative to the air duct body, thereby adjusting the wind direction, enabling the air outlet wind direction to be adjusted at an angle according to requirements, targeting the defrosting area for defrosting, avoiding the divergence of wind force, and achieving defrosting through the diffusion of waiting time, improving the defrosting efficiency.

[0025] 3. As a preferred embodiment of the present invention, multiple air guiding blades are arranged at intervals along the air outlet; the end face of the air guiding blade can be attached to the inner wall of the air duct body; a connecting rod extending outside the air duct body is connected to the end face of the air guiding blade to form the connecting part of the air guiding blade.

[0026] The air guiding blades are arranged at intervals along the air outlet to achieve uniform adjustment of the wind direction. The air flow sent out from the air outlet can be evenly divided into multiple air flows and transported outward under the guidance of multiple air guiding blades, which can expand the coverage range of the wind force, cover the corner areas, and achieve comprehensive defrosting of the front windshield. The end face of the air guiding blade is attached to the inner wall of the air duct body to prevent gaps from appearing between the air guiding blade and the air duct body, so that the wind force is output between the air guiding blades, improving the air supply capacity; in order to enable the air guiding blade to swing within the air duct body, the end of the air guiding blade needs to have a connecting rod extending outside the air duct body. The air guiding blade is rotationally connected to the air duct body through the connecting rod, and the relative rotation of the air guiding blade relative to the air duct body by a preset angle can be realized through the connection between the connecting rod and the guiding member, achieving the adjustment of the wind direction.

[0027] 4.

[0028] When the guiding member drives the connecting member to rotate, the guiding vane can rotate together with the connecting rod. It is necessary to connect the connecting rod and the connecting member. Therefore, the connecting rod is designed to have a slot, and the connecting member is designed to have a clamping member that matches the slot, or the connecting rod is designed to have a clamping member and the connecting member has a slot. In short, the connection between the connecting rod and the connecting member is achieved by the cooperation of the slot and the clamping member. With this setting, the connection between the connecting member and the connecting rod becomes a detachable connection. After the connecting rod and the connecting member are connected, their relative positions are fixed and they will not move relative to each other. Therefore, when the connecting member makes a turning motion under the action of the guiding member, the connecting rod can follow the connecting member and make a turning motion synchronously, so as to realize the swinging motion of the guiding vane relative to the air duct body and realize the adjustment of the wind direction.

[0029] 5. As a preferred embodiment of the present invention, the driving mechanism includes a housing, a driving motor and a gear. The housing is connected to the outside of the air duct body to form a fixed part of the driving mechanism; the driving motor is connected inside the housing; the gear is connected to the output shaft of the driving motor to form a rotating part of the driving mechanism.

[0030] The housing of the driving mechanism, as the fixed part of the driving mechanism, is used to fixedly connect the entire driving mechanism to the air duct body. A gear that forms the rotating part of the driving mechanism is arranged on the output shaft of the driving motor inside the housing, and is used to mesh with the guiding member having a rack, so that when the gear rotates, the guiding member makes a linear motion relative to the air duct body, realizing the provision of driving force for the swinging of the connecting member. The swinging of the connecting member can realize the swinging of the connected connecting rod, thereby realizing the swinging of the guiding vane and finally realizing the adjustment of the wind direction.

[0043] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the drawings of the specification

[0044] The utility model relates to an adjustable defrosting air duct system for an automobile. As Figure 1-2 shown, it includes an air duct body 1 having an air inlet 11 and an air outlet 12 arranged oppositely; a transmission device 2 connected to the outer side of the air duct body 1 near the air inlet 11; the transmission device 2 includes a driving mechanism 21 connected to the air duct body 1, a guide member 22 connected to the driving mechanism 21, and a connecting member 23 connected to the guide member 22; a blade assembly having a plurality of air guiding blades 3 connected to the inside of the air duct body 1 corresponding to the air outlet 12, and the air guiding blades 3 have connecting portions extending outside the air duct body 1 and perpendicularly connected to the connecting member 23; by driving the guide member 22 to move along the air duct body 1 by the driving mechanism 21 to drive the connecting member 23 to rotate, so that the air guiding blades 3 swing relative to the air duct body 1 to adjust the air direction of the air outlet 12.

[0045] The air flow enters the air duct body 1 through the air inlet 11 of the air duct body 1, passes through the blade assembly to adjust the air direction, and is sent out from the air outlet 12, so as to blow different areas of the front windshield to achieve defrosting, avoiding the traditional defrosting method that can only spread gradually from the local area to the surrounding area. The blade assembly of the present application includes a plurality of air guiding blades 3 that swing relative to the air duct body 1, and the air flow flows out between the air guiding blades 3 to realize the adjustment of the air direction, avoiding the traditional fixed air direction, and can realize the free adjustment of the air direction, can effectively and specifically defrost according to different frosting areas on the front windshield, avoid the waste of wind force, can concentrate the wind force to perform defrosting operation on the frosting area, and improve the defrosting efficiency.

[0046] As a preferred implementation manner, the driving mechanism 21 has a fixing portion fixed to the outer side of the air duct body 1 and a rotating portion connected to the guide member 22; the first positioning end of the guide member 22 cooperates with the rotating portion, and the guide member 22 can move relative to the air duct body 1 under the driving action of the rotating portion, and the connecting member 23 is connected to the second positioning end of the guide member 22, so that the connecting member 23 swings a preset angle relative to the air duct body 1 under the moving action of the guide member 22.

[0047] The driving mechanism 21, as a device that provides driving force, drives the guiding member 22 to linearly move relative to the air duct body 1 during the rotation of its rotating part relative to the air duct body 1, realizing the conversion of the rotational motion of the driving mechanism 21 into the linear motion of the guiding member 22. During the linear motion of the guiding member 22, it can drive the connecting member 23 to swing relative to the air duct body 1. Since the connecting part of the connecting member 23 and the air guiding blade 3 is vertically connected, and the connecting member 23 is connected to the second positioning end of the guiding member 22, the linear movement of the guiding member 22 drives the connecting member 23 and the air guiding blade 3 to swing relative to the air duct body 1, thereby adjusting the wind direction, enabling the wind direction of the air outlet 12 to be adjusted at an angle according to requirements, defrosting the frosting area targeted, avoiding the divergence of wind force, and realizing defrosting through the diffusion of waiting time, improving the defrosting efficiency.

[0048] As a preferred embodiment, a plurality of air guiding blades 3 are arranged at intervals along the air outlet 12; the end face of the air guiding blade 3 can be attached to the inner wall of the air duct body 1; a connecting rod 4 extending outside the air duct body 1 is connected to the end face of the air guiding blade 3, forming the connecting part of the air guiding blade 3.

[0049] The air guiding blades 3 are arranged at intervals along the air outlet 12 to achieve uniform adjustment of the wind direction. The air flow sent out from the air outlet 12 can be evenly divided into multiple air flows and transported outward under the guidance of the plurality of air guiding blades 3, which can expand the coverage range of the wind force and can cover the corner areas, realizing comprehensive defrosting of the front windshield. The end face of the air guiding blade 3 is attached to the inner wall of the air duct body 1 to prevent gaps from appearing between the air guiding blade 3 and the air duct body 1, causing the wind force to spread everywhere, so that the wind force is output from between the air guiding blades 3, improving the air supply capacity; in order to enable the air guiding blade 3 to swing within the air duct body 1, the end of the air guiding blade 3 needs to have a connecting rod 4 extending outside the air duct body 1. The air guiding blade 3 is rotationally connected to the air duct body 1 through the connecting rod 4, and the relative rotation of the air guiding blade 3 relative to the air duct body 1 by a preset angle can be realized through the connection between the connecting rod 4 and the guiding member 22, achieving the adjustment of the wind direction.

[0050] As Figure 2 shown, in order to adapt to the structure of the air duct body 1, the shape of the air guiding blade 3 is adapted to the shape of the internal cavity of the air duct body 1. A connecting rod 4 protruding from the air guiding blade 3 is connected to the right side of the air guiding blade 3. The connecting rod 4 can be connected to the right mounting hole of the air duct body 1, and the connecting rod 4 can extend out of the mounting hole to be connected to the connecting member 23. A positioning rod 9 protruding from the end face of the air guiding blade 3 is connected to the left side of the air guiding blade 3. The positioning rod 9 can be connected to the left mounting hole of the air duct body 1 and extend outside the air duct body 1. Through the positioning rod 9 and the connecting rod 4, the air guiding blade 3 is rotationally connected within the air duct body 1.

[0051] Furthermore, the connecting rod 4 has a card slot, and the connecting member 23 has a clamping member that cooperates with the card slot; alternatively, the connecting member 23 has a card slot, and the connecting rod 4 has a clamping member that cooperates with the card slot; the connecting rod 4 and the connecting member 23 are connected by connecting the card slot and the clamping member.

[0052] When the guiding member 22 drives the connecting member 23 to rotate, the air guiding vane 3 can rotate together with the connecting rod 4. Therefore, it is necessary to fixedly connect the connecting rod 4 and the connecting member 23. So, the connecting rod 4 is designed to have a card slot, and the connecting member 23 is designed to have a clamping member that cooperates with the card slot, or the connecting rod 4 is designed to have a clamping member, and the connecting member 23 has a card slot; the connection between the connecting rod 4 and the connecting member 23 is realized by the cooperation of the card slot and the clamping member. With such a setting, a detachable connection is formed between the connecting member 23 and the connecting rod 4. After the connecting rod 4 and the connecting member 23 are connected, their positions are locked with each other, and a locking connection is formed between the connecting rod 4 and the connecting member 23. Therefore, when the connecting member 23 makes a turning motion under the action of the guiding member 22, the connecting rod 4 can follow the connecting member 23 to make a synchronous turning motion, thereby realizing the swinging motion of the air guiding vane 3 relative to the air duct body 1 and realizing the adjustment of the wind direction.

[0053] As a preferred embodiment, the driving mechanism 21 includes a housing 211, a driving motor, and a gear 212. The housing 211 is connected to the outside of the air duct body 1 to form a fixing part of the driving mechanism 21; the driving motor is connected to the inside of the housing 211; the gear 212 is connected to the output shaft of the driving motor to form a rotating part of the driving mechanism 21.

[0054] The housing 211 of the driving mechanism 21, as the fixing part of the driving mechanism 21, is used to fixedly connect the entire driving mechanism 21 to the air duct body 1. The housing 211 is fixedly connected to the housing 211 through fasteners such as screws 10 or bolts. A gear 212 forming the rotating part of the driving mechanism 21 is arranged on the output shaft of the driving motor inside the housing 211, which is used to mesh and cooperate with the guiding member 22 having a rack 8. When the gear 212 rotates, the guiding member 22 makes a linear motion relative to the air duct body 1, providing a driving force for the swinging of the connecting member 23. The swinging of the connecting member 23 can realize the swinging of the connected connecting rod 4, thereby realizing the swinging of the air guiding vane 3 and finally realizing the adjustment of the wind direction.

[0055] As a preferred embodiment, an insertion port 5 is provided on one side of the housing 211 for inserting a wire harness terminal. As Figure 1 shown, an insertion port 5 is opened on the right side of the housing 211, and the wire harness terminal can draw power for the motor from the whole vehicle.

[0056] As a preferred embodiment, there are a plurality of convex portions 6 corresponding to and connected with a connecting member 23 on the extending direction of the guiding member 22, forming the second positioning end of the guiding member 22; on the side of the guiding member 22 facing the driving mechanism 21, there is a rack 8 meshing with the gear 212, and the rack 8 forms the first positioning end of the guiding member 22.

[0057] As Figure 1 shown, the guiding member 22 has a connecting rod structure, and a plurality of convex portions 6 protruding from the top of the guiding member 22 are arranged at intervals in the extending direction of the guiding member 22. The convex portion 6 has an arc transition surface. The convex portion 6 serves as the second positioning end of the guiding member 22 for connecting with the connecting member 23. A rack 8 meshing with the gear 212 is provided at the bottom of the guiding member 22. Thus, when the gear 212 rotates relative to the air duct body 1 under the drive of the motor, the guiding member 22 can be driven to move left and right along the air duct body 1. Since the second positioning end of the guiding member 22 is connected with the connecting member 23, the connecting member 23 can be driven to rotate relative to the air duct body 1, or rather relative to the convex portion 6. Since the connecting member 23 is connected with the air guiding blade 3, the air guiding blade 3 can be driven to swing a preset angle relative to the air duct body 1, realizing the adjustment of the wind direction.

[0058] Regarding the specific connection manner between the convex portion 6 and the connecting member 23, it can be not limited to any of the following embodiments:

[0059] Embodiment 1: The convex portion 6 is provided with a groove, and the connecting member 23 has a convex rod 7 adapted to the groove. The convex rod 7 is connected with the groove, so that the connecting member 23 is connected with the guiding member 22.

[0060] As Figure 1 shown, described according to the orientation shown in the figure, only for the convenience of clear description, and not limiting the specific orientation: The structure of the connecting member 23 is an L-shaped structure. The first end and the second end of the connecting member 23 are perpendicular. The first end of the connecting member 23 is distributed vertically, and the second end of the connecting member 23 is distributed horizontally perpendicular to the first end of the connecting member 23. A convex rod 7 structure protruding towards the driving mechanism 21 is connected to the second end of the connecting member 23. The convex rod 7 at the second end of the connecting member 23 can be inserted into the groove opened in the convex portion 6, thus realizing the connection between the connecting member 23 and the convex portion 6. When in use, when the guiding member 22 moves left and right in a straight line, the convex portion 6 moves left and right in a straight line. The convex rod 7 at the second end of the connecting member 23 can move left and right following the convex portion 6 in the groove of the convex portion 6, and the convex rod 7 can rotate in the groove of the convex portion 6, so that the first end of the connecting member 23 rotates relative to the air duct body 1. Since the first end of the connecting member 23 is fixedly connected with the connecting rod 4 of the air guiding blade 3, the connecting rod 4 and the air guiding blade 3 are driven to rotate relative to the air duct body 1. Therefore, the swinging of the air guiding blade 3 is realized by the left and right movement of the guiding member 22.

[0061] Embodiment 2: A positioning portion for clamping with the connecting member 23 is formed on one side of the convex portion 6; the driving mechanism 21 drives the guiding member 22 to move, and drives the connecting member 23 to swing relative to the air duct body 1 through the positioning portion.

[0062] A positioning portion for clamping the connecting member 23 is provided on one side of the convex portion 6. A positioning groove is provided in the positioning portion. A roller is provided at the bottom of the connecting member 23. The roller can be slidably connected along the positioning groove in the positioning portion. When the convex portion 6 moves linearly left and right, the roller is driven to slide along the positioning groove and follow the convex portion 6 to achieve horizontal movement, so as to drive the air guiding blade 3 fixedly connected to the connecting member 23 to swing horizontally in the air duct body 1, realizing the adjustment of the wind direction.

[0063] This application also relates to a vehicle, which is based on the above-mentioned adjustable defrosting air duct system for an automobile.
