Description

Technical Field

[0001] This utility model relates to the technical field of vehicle air conditioning vents, specifically a dual-channel automotive air conditioning vent. Background Technology

[0002] Car air conditioning vents are an important interior component of a car. They are usually located in the driver's cabin or diagonally above the passenger seat. When it is necessary to adjust the temperature inside the car, the air conditioning can be turned on to cool or heat the car, and the air will blow out from the air conditioning vents to bring comfort to the passengers.

[0003] In the air conditioning vents of automobiles, in order to control the direction of airflow discharged from the air conditioning duct, multiple longitudinal blades and multiple transverse blades are respectively installed at the air conditioning vents. The multiple longitudinal blades are used to adjust the airflow in the left and right directions, and the multiple transverse blades are used to adjust the airflow in the up and down directions. In the prior art, a key is slidably installed on the transverse blades to control both the up and down adjustment of the transverse blades and the left and right adjustment of the longitudinal blades. After adjusting the transverse blades and the longitudinal blades respectively by the key, the longitudinal blades will necessarily be fixed when the transverse blades are fixed.

[0004] The existing transverse blades rotate by engaging with the fixed plate via pins at both ends of the transverse blades. The positioning of the transverse blades after angle adjustment is also achieved through an interference fit between the pins and the fixed plate. After prolonged use, the transverse blades are prone to wear between the pins and the fixed plate. Wear can cause the pins to become thinner or the inner diameter of the fixed plate to become thicker, gradually changing the interference fit between the pins and the fixed plate into a clearance fit. At this point, multiple transverse blades cannot be positioned after adjustment. Due to the downward force of the weight of multiple transverse blades, the air conditioning vents may be closed, affecting the normal ventilation of the vehicle's air conditioning system. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-channel automotive air conditioning vent. By limiting multiple lateral blades through a limiting component, even when the pin and the fixing plate are in clearance fit, multiple lateral blades can still be limited, thus avoiding the problem of the air conditioning vent closing due to the closure of the lateral blades, which would affect the normal ventilation of the vehicle's air conditioning system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-channel automotive air conditioning vent, comprising a snap-fit ​​plate and two symmetrically arranged ventilation openings on the snap-fit ​​plate. Longitudinal fixing plates are provided on the rear wall of the snap-fit ​​plate and on both sides of the ventilation openings. Multiple transverse blades are rotatably arranged between the two longitudinal fixing plates. The multiple transverse blades are all hinged to a first synchronous rod. A limiting component that cooperates with one of the transverse blades is fixedly provided on the rear wall of the snap-fit ​​plate.

[0007] Preferably, multiple through holes are symmetrically provided on both longitudinal fixing plates, and pins that cooperate with the through holes are fixedly provided at both ends of the transverse blade.

[0008] Preferably, the limiting assembly includes a fixed shaft fixedly disposed at the end of the pin, a retaining cylinder fixedly disposed on the rear wall of the buckle plate, and a mounting plate fixedly disposed on the outer wall of the longitudinal fixed plate. The outer wall of the fixed shaft is provided with a plurality of first racks. A connecting rod penetrating the buckle plate is slidably disposed inside the retaining cylinder. A pressing handle is fixedly disposed at one end of the connecting rod, and an arc-shaped plate is fixedly disposed at the other end. A plurality of second racks cooperating with the first racks are fixedly disposed on the inner side of the arc-shaped plate. A spring is disposed between the connecting rod and the mounting plate.

[0009] Preferably, a guide protrusion is fixedly provided on the inner wall of the retaining cylinder, and a guide groove that cooperates with the guide protrusion is provided on the outer wall of the connecting rod.

[0010] Preferably, a transverse fixing plate is provided on the rear wall of the buckle plate and on both the upper and lower sides of the vent. A plurality of longitudinal blades are rotatably provided between the two transverse fixing plates and on the rear side of the transverse blades. The plurality of longitudinal blades are hinged to the second synchronous rod. A key is slidably provided on the transverse blades for controlling the angle adjustment of the transverse blades and the longitudinal blades respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a limiting component that engages with a pin is fixedly installed on the rear wall of the buckle plate and on the longitudinal fixing plate. The limiting component limits one of the transverse blades. Since multiple transverse blades are hinged together by a first synchronizing rod, when one transverse blade is limited, multiple adjacent transverse blades are still limited. Even when the transverse blades are adjusted for a long time and the pin and the fixing plate become clearance fit, multiple transverse blades can still be limited. The limiting component avoids the problem of the air conditioning vents being closed due to the closure of the transverse blades, thus affecting the normal ventilation of the vehicle's air conditioning system.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, the dual-channel automotive air conditioning vent includes a clip plate 1 that mates with the center console, combined with... Figure 1 As shown, the buckle plate 1 has two ventilation openings 2, combined with Figure 1 , Figure 2 and Figure 3 As shown, longitudinal fixing plates 3 are provided on the rear wall of the buckle plate 1 and on both sides of the ventilation opening 2. Multiple transverse blades 5 for controlling airflow direction are rotatably arranged between the two longitudinal fixing plates 3. Furthermore, combined with... Figure 3 As shown, multiple through holes 4 are symmetrically opened on both longitudinal fixed plates 3. Pins 6 that cooperate with the through holes 4 are fixedly installed at both ends of the transverse blades 5. The multiple transverse blades 5 are all hinged to the first synchronizing rod 7. Preferably, the first synchronizing rod 7 is used to control the multiple transverse blades 5 to rotate synchronously.

[0021] Specifically in this embodiment, combined with Figure 3 As shown, a limiting component 12 that cooperates with one of the transverse blades 5 is fixedly installed on the rear wall of the buckle plate 1. Furthermore, combined with... Figure 4As shown, the limiting assembly 12 includes a fixed shaft 1201 fixedly disposed at the end of the pin 6, a retaining cylinder 1202 fixedly disposed on the rear wall of the buckle plate 1, and a mounting plate 1203 fixedly disposed on the outer wall of the longitudinal fixing plate 3. A plurality of first racks 1204 are disposed on the outer wall of the fixed shaft 1201. A connecting rod 1206 penetrating the buckle plate 1 is slidably disposed inside the retaining cylinder 1202. A guide protrusion 1205 is fixedly disposed on the inner wall of the retaining cylinder 1202. A guide groove 1207 cooperating with the guide protrusion 1205 is formed on the outer wall of the connecting rod 1206. Preferably, the guide protrusion 1205 and the guide groove 1207 are... The mechanism prevents the connecting rod 1206 from rotating within the retaining cylinder 1202. One end of the connecting rod 1206 is fixedly provided with a pressing handle 1208, and the other end is fixedly provided with an arc-shaped plate 1209. Multiple second racks 1210 that cooperate with the first rack 1204 are fixedly provided on the inner side of the arc-shaped plate 1209. A spring 1211 is provided between the connecting rod 1206 and the mounting plate 1203. Preferably, both the connecting rod 1206 and the mounting plate 1203 are symmetrically provided with limiting posts for limiting the spring 1211, so that the spring 1211 can pop out between the connecting rod 1206 and the mounting plate 1203 when it retracts.

[0022] In a further preferred embodiment, one of the transverse blades 5 is limited by the limiting component 12. Since the first synchronizing rod 7 is hinged between the multiple transverse blades 5, when one transverse blade 5 is limited, the multiple adjacent transverse blades 5 are still limited. When the transverse blades 5 are adjusted for a long time and the pin 6 and the fixing plate become clearance fit, the multiple transverse blades 5 can still be limited. The setting of the limiting component 12 avoids the problem of the air conditioning outlet being closed due to the closure of the transverse blades 5, thereby affecting the normal exhaust of the air conditioning in the vehicle.

[0023] Specifically in this embodiment, combined with Figure 3 As shown, a horizontal fixing plate 8 is provided on the rear wall of the buckle plate 1 and on both the upper and lower sides of the ventilation opening 2. A plurality of longitudinal blades 9 are rotatably provided between the two horizontal fixing plates 8 and on the rear side of the horizontal blade 5. The plurality of longitudinal blades 9 are all hinged to the second synchronous rod 10. A key 11 is slidably provided on the horizontal blade 5 for controlling the angle adjustment of the horizontal blade 5 and the longitudinal blade 9 respectively.

[0024] Working principle:

[0025] Before adjusting the transverse blade 5, first press the handle 1208 inward with your finger to make the connecting rod 1206 slide inward on the retaining sleeve 1202. During the inward sliding of the connecting rod 1206, the spring 1211 contracts, and the second rack 1210 on the inner side of the arc plate 1209 separates from the first rack 1204, thus removing the limit on the transverse blade 5. At this time, the rotation of the transverse blade 5 at the up and down angle can be adjusted by using the key 11.

[0026] After the angle of the transverse blade 5 is adjusted, the pressing of the pressing handle 1208 is canceled. At this time, the second rack 1210 is pushed to engage with the first rack 1204 by the elastic force of the spring 1211. After the second rack 1210 engages with the first rack 1204, the transverse blade 5 is limited. At this time, the rotation of the longitudinal blade 9 can only be adjusted by the key 11, and the up and down rotation of the transverse blade 5 cannot be adjusted.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
