Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts fall within the protection scope of the utility model.

[0025] Please refer to Figures 1-5 The utility model provides a technical scheme:

[0026] A kind of air conditioner air duct inner cavity guide plate for vehicle, including air duct 1 and guide plate 2, guide plate 2 is arranged in the inner wall of air duct 1, the upper portion of guide plate 2 is fixedly connected with connecting block 6, the surface of connecting block 6 is vertically elastically movably connected with two spherical lock blocks 7, the inner wall of air duct 1 is fixedly connected with connecting seat 4, connecting seat 4 is provided with second cavity 10 in the inside, connecting block 6 is inserted in the inside of second cavity 10, the inner wall of second cavity 10 is provided with two lock holes 11, two spherical lock blocks 7 are respectively clamped in two lock holes 11, connecting seat 4 is provided with through -hole 16, through -hole 16 is coaxially arranged with second cavity 10, the surface of connecting block 6 is provided with two first cavities 8 along the radial direction, two spherical lock blocks 7 are respectively slidably connected in the inside of first cavity 8, first spring 9 is fixedly connected between spherical lock block 7 and first cavity 8.

[0027] Please refer to Figures 1 to 3In the prior art, the guide plate 2 is fixedly connected inside the air duct 1 and is also horizontally slidingly connected with the sliding plate on one side of the guide plate 2. Therefore, in the embodiment, the guide plate 2 is separated from the air duct 1 by horizontally pushing the guide plate 2 to move, and the guide plate 2 is separated from the sliding plate, so that the guide plate 2 is disassembled. The connecting block 6 is pushed to move inside the through hole 16, and the connecting block 6 can drive the two ball-shaped lock blocks 7 to synchronously move when moving. At this time, the ball-shaped lock blocks 7 are extruded with the lock holes 11, and the lock holes 11 extrude the ball-shaped lock blocks 7 to make them enter the first cavities 8 and compress and store the first springs 9 until the ball-shaped lock blocks 7 are separated from the inside of the lock holes 11. With the continuous pushing of the connecting block 6, the connecting block 6 can be finally separated from the inside of the second cavities 10, so that the base 3 is separated from the connecting seat 4, and the guide plate 2 is disassembled from the inside of the air duct 1.

[0028] The push rod 12 is coaxially and elastically slidingly connected inside the through hole 16. One end of the push rod 12 abuts against one end of the connecting block 6. The one end of the push rod 12 is fixedly installed with the limiting plate 14. The second spring 13 is fixedly connected between the push rod 12 and the limiting plate 14.

[0029] Please refer to Figure 2 In the embodiment, the connecting block 6 is pushed to move inside the through hole 16 to separate it from the inside of the second cavities 10. The specific method is as follows: when the automobile is maintained, the staff disassembles the cover plate and the air outlet in the prior art. At this time, the limiting plate 14 can be pushed by hand. The limiting plate 14 can drive the push rod 12 to push the connecting block 6 inside the through hole 16. At the same time, the distance between the limiting plate 14 and the connecting seat 4 is reduced, so that the second spring 13 is compressed and stored. Since the guide plate 2 can be laterally translated on both sides under the driving of the connecting seat 4 and the base 3, the guide plate 2 can be separated from the sliding plate in the prior art under the state of force balance, so that the guide plate 2 is disassembled. At this time, the staff releases the limiting plate 14, and the second spring 13 can drive the limiting plate 14 and the push rod 12 to reset by the elastic force of the second spring 13, so as to reinstall the guide plate 2 inside the air duct 1 after cleaning the guide plate 2.

[0030] It should be noted that the connection between the sliding plate and the guide plate 2 in the prior art is a sliding connection, and it can be known from the figure that the sliding plate is engaged on one side of the guide plate 2 by the elasticity of the sliding plate. Therefore, in the embodiment, the guide plate 2 is pushed away from the sliding plate to separate the connection between the two, so as to disassemble the guide plate 2.

[0031] The inner wall of the second cavity 10 is provided with two arc-shaped guide grooves 15. The two arc-shaped guide grooves 15 are respectively communicated with the two lock holes 11. The arc-shaped guide grooves 15 are coincided with the central axes of the lock holes 11.

[0032] Please refer to Figure 3 When the base 3 and the connecting seat 4 are connected, the connection of the spherical locking block 7 and the locking hole 11 needs to be realized, and in the embodiment, the spherical surface part of the spherical locking block 7 can slide inside the arc-shaped guide groove 15 so as to enter the inside of the locking hole 11, wherein the connecting part of the arc-shaped guide groove 15 and the end face of the connecting seat 4 is provided with a round corner so that the spherical locking block 7 can smoothly enter the arc-shaped guide groove 15.

[0033] The side wall of the air duct 1 is provided with a sliding groove 5, the side wall of the flow guide plate 2 is elastically connected with a sliding block 17, the sliding block 17 is slidingly connected in the sliding groove 5, the side wall of the flow guide plate 2 is provided with a third cavity 19, the sliding block 17 is slidingly connected inside the third cavity 19 along the axial direction of the third cavity 19, the third spring 18 is fixedly connected between the third cavity 19 and the sliding block 17, the sliding groove 5 is divided into an inclined section 20 and a horizontal section 21, the depth of the inclined section 20 gradually decreases away from the flow guide plate 2, and the end of the inclined section 20 is flush with the side wall of the air duct 1.

[0034] Please refer to Figure 4 and Figure 5 When the flow guide plate 2 is pushed, the sliding block 17 can slide inside the horizontal section 21 of the sliding groove 5, and at this time, the third spring 18 is in a natural state, when the base 3 and the connecting seat 4 are separated, the flow guide plate 2 needs to be taken out from the inside of the air duct 1, so the flow guide plate 2 can be taken out along the path of the inclined section 20 of the sliding groove 5, at this time, the sliding block 17 can enter the inclined section 20 from the horizontal section 21, and as the depth of the inclined section 20 gradually decreases, the distance between the side wall of the inclined section 20 and the side wall of the flow guide plate 2 gradually decreases, so the sliding groove 5 can gradually move towards the inside of the third cavity 19 and compress the third spring 18, until the sliding block 17 is completely separated from the inside of the sliding groove 5, and at this time, the flow guide plate 2 can be completely taken out from the inside of the air duct 1, so as to be cleaned.

[0035] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
