Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and particularly relates to an air duct for an automobile air conditioner. Background Technique

[0002] The automobile air conditioning system is composed of multiple scattered components, such as a compressor, a condenser, an evaporator, etc. These components are connected to form a complete system to ensure the smooth flow of refrigerant or air. The main function of the air duct is to deliver the processed cold air or warm air to all corners of the vehicle to provide a comfortable riding environment for passengers.

[0003] After the air duct is used for a long time, dust and dirt will accumulate on the air filter, which may affect the smooth air circulation and the air quality in the vehicle. Moreover, leakage may occur during use, resulting in a decrease in the cooling or heating effect, and dust may fall into the air duct due to shaking and collision during disassembly. Therefore, a new solution is proposed here. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide an air duct for an automobile air conditioner to solve the technical problem that after the current air duct is used for a long time, dust and dirt will accumulate on the air filter, and dust may fall into the air duct due to shaking and collision during disassembly.

[0005] To achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: design an air duct for an automobile air conditioner, including an air duct main body, a connecting rope, a cross bar and an insertion frame. A bottom block is fixedly connected to the bottom of the right side wall of the insertion frame, and a blocking plate is movably connected to the edge of the insertion frame above the bottom block through a hinge. A convex block is fixedly connected to the top surface of the end of the blocking plate away from the insertion frame. The two ends of the connecting rope are respectively fixedly connected to the center of the top of the cross bar and the top of the convex block, and the connecting rope passes through the surface of the insertion frame above the filter screen. A filter screen is fixedly connected to the center inside the insertion frame. Sliding grooves are respectively opened on the front and rear inner side walls of the insertion frame on the left side of the filter screen. The left and right ends of the cross bar are respectively located inside the two sliding grooves and are slidably connected inside the sliding grooves. Magnet bars are fixedly embedded on the surfaces of the insertion frame above and below the cross bar. The width of the magnet bar is the same as the width of the cross bar. A number of second magnet blocks are evenly fixedly embedded on the top and bottom of the cross bar.

[0006] Preferably, an air outlet frame is fixedly connected to the top of the air duct main body. Telescopic grooves are respectively opened on the upper and lower inner surfaces of the opening of the air outlet frame. A telescopic block is vertically slidably connected inside the telescopic groove, and a number of springs are fixedly connected between the telescopic block and the inner wall of the telescopic groove.

[0007] Preferably, a dialing block is fixedly connected to the bottom edge of the surface of the horizontal bar away from the filter screen.

[0008] Preferably, first magnet blocks with the same size are fixedly inlaid at the bottom of the blocking plate directly below the convex block and the top end of the bottom block.

[0009] Preferably, side baffles are fixedly connected to the front and rear edges of the blocking plate.

[0010] Preferably, the bottom of the blocking plate fits against the top end of the bottom block, and the length and width of the blocking plate are the same as those of the blocking plate.

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

[0012] 1. In the present utility model, through the horizontal bar, the sliding groove, and the connecting rope sliding into the blocking plate, the floating back of dust can be reduced. Before disassembly, the dialing block is downwardly toggled, and the horizontal bar moves downward along the sliding groove. During the downward movement, one end of the connecting rope will move along with the horizontal bar, and the other end of the connecting rope will pull up one end of the blocking plate, causing the blocking plate to lift and incline, thereby forming a blocking inclined plane at the rear side of the filter screen, minimizing the problem that dust falls back into the air outlet frame and the air duct main body during the disassembly process due to shaking and jitter, resulting in difficult cleaning, and improving the practicability.

[0013] 2. In the present utility model, through the magnet strip, the horizontal bar, and the second magnet block, the horizontal bar can be fixed. Before pulling the blocking plate, the second magnet block at the top end of the horizontal bar adsorbs the horizontal bar on the surface of the upper magnet strip. After downwardly toggling the horizontal bar, it is until the second magnet block at the bottom of the horizontal bar adsorbs on the surface of the lower magnet strip, thereby ensuring the fixation of the horizontal bar in the up and down positions, avoiding the free shaking of the blocking plate, and ensuring the stability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0019] Embodiment 1: An air duct for an automotive air conditioner. Refer to Figures 1 to 3 , an air duct for an automotive air conditioner, comprising an air duct main body 1, a connecting rope 11, a cross bar 12, and an insertion frame 6. A bottom block 8 is fixedly connected to the bottom of the right side wall of the insertion frame 6, and a blocking plate 9 is movably connected to the edge of the insertion frame 6 above the bottom block 8 through a hinge. A convex block 10 is fixedly connected to the top surface of the end of the blocking plate 9 away from the insertion frame 6. Two ends of the connecting rope 11 are respectively fixedly connected to the center of the top of the cross bar 12 and the top of the convex block 10, and the connecting rope 11 passes through the surface of the insertion frame 6 above the filter screen 7. A filter screen 7 is fixedly connected to the center inside the insertion frame 6. Sliding grooves 13 are formed in the front and rear inner side walls of the insertion frame 6 on the left side of the filter screen 7. The left and right ends of the cross bar 12 are respectively located inside the two sliding grooves 13 and are slidably connected inside the sliding grooves 13. One end of the connecting rope 11 moves together with the cross bar 12, and the other end of the connecting rope 11 will pull up one end of the blocking plate 9, causing the blocking plate 9 to lift and incline, thereby forming a blocking inclined plane at the rear of the filter screen 7, minimizing the problem that dust falls back into the air outlet frame 2 and the air duct main body 1 during the disassembly process due to shaking and vibration, resulting in difficult cleaning.

[0020] At the same time, magnet bars 15 are fixedly inlaid and connected to the surfaces of the insertion frame 6 directly above and directly below the cross bar 12. The width of the magnet bars 15 is the same as the width of the cross bar 12. A number of second magnet blocks 14 are uniformly fixedly inlaid and connected to the top and bottom of the cross bar 12. Before pulling the blocking plate 9, the second magnet blocks 14 at the top of the cross bar 12 adsorb the cross bar 12 on the surface of the upper magnet bar 15. After the cross bar 12 is toggled downward, the second magnet blocks 14 at the bottom of the cross bar 12 adsorb on the surface of the lower magnet bar 15, thereby ensuring the fixation of the cross bar 12 in the up and down positions and preventing the blocking plate 9 from freely shaking and causing dust to disperse.

[0021] Specifically, refer to Figure 3 , an air outlet frame 2 is fixedly connected to the top of the air duct main body 1. Telescopic grooves 3 are formed in the upper and lower inner surfaces of the opening of the air outlet frame 2. Telescopic blocks 5 are vertically slidably connected inside the telescopic grooves 3, and a number of springs 4 are fixedly connected between the telescopic blocks 5 and the inner walls of the telescopic grooves 3. When the insertion frame 6 is inserted, the telescopic blocks 5 will be squeezed into the telescopic grooves 3. After the insertion frame 6 is completely inserted, the telescopic blocks 5 will pop out again, thereby restricting and clamping the insertion frame 6 and ensuring the stability of the filter screen 7.

[0022] Furthermore, refer to Figure 3 , a dial block 121 is fixedly connected to the bottom edge of the surface of the cross bar 12 away from the filter screen 7. The dial block 121 can increase the force application point and facilitate manually toggling the dial block 121 to remove the cross bar from the surface of the upper magnet bar 15.

[0023] It should be noted that, referring to Figure 3 , at the bottom of the blocking plate 9 directly below the bump 10 and at the top of the bottom block 8, first magnet blocks 801 with the same size are fixedly inlaid and connected. The first magnet blocks 801 attract the blocking plate 9 and the bottom block 8 together, preventing the blocking plate 9 from shaking and lifting by itself, which may affect the normal ventilation of the ventilation pipe. Only by pulling the connecting rope 11 can the blocking plate 9 and the bottom block 8 be separated, and the connecting rope 11 is always in a taut state.

[0024] It is worth noting that, referring to Figure 3 , on both front and rear edges of the blocking plate 9, side baffles 901 are fixedly connected. The side baffles 901 can block both sides of the blocking plate 9. When the cross bar 12 is adsorbed on the magnet bar 15 below, at this time, the left end of the blocking plate 9 just fits against the right surface of the insertion frame 6, thus forming a space similar to a triangular prism between the blocking plate 9 and the insertion frame 6, which is convenient for receiving the dust shaken off from the filter screen 7.

[0025] It is worth introducing that, referring to Figure 1 and Figure 3 , the bottom of the blocking plate 9 fits against the top of the bottom block 8, and the length and width of the blocking plate 9 are the same as those of the blocking plate 9, thus not affecting the normal disassembly and assembly of the insertion frame 6 and not affecting the normal ventilation of the ventilation pipe.

[0026] Working principle: By sliding the cross bar 12, the sliding groove 13, and the connecting rope 11 into the blocking plate 9, the floating back of dust can be reduced. Before disassembly, the toggle block 121 is toggled downward, and the cross bar 12 moves downward along the sliding groove 13. During the downward movement, one end of the connecting rope 11 will move along with the cross bar 12, while the other end of the connecting rope 11 will lift one end of the blocking plate 9, causing the blocking plate 9 to lift and tilt, thus forming a blocking inclined plane at the rear side of the filter screen 7, minimizing the problem that dust falls back into the air outlet frame 2 and the air duct main body 1 during disassembly due to shaking and vibration, which is difficult to clean, and improving the practicability. At the same time, through the magnet bar 15, the horizontal bar 12, and the second magnet block 14, the cross bar 12 can be fixed. Before pulling the blocking plate 9, the second magnet block 14 at the top of the cross bar 12 adsorbs the cross bar 12 on the surface of the upper magnet bar 15. After toggling the cross bar 12 downward, it is until the second magnet block 14 at the bottom of the cross bar 12 adsorbs on the surface of the lower magnet bar 15, thus ensuring the fixation of the cross bar 12 in the up and down positions, preventing the blocking plate 9 from shaking freely, and ensuring stability; during installation, the bottom block 8 is directly aligned with the air outlet frame 2, and then the insertion frame 6 is pushed inward. The telescopic block 5 retracts into the telescopic groove 3 due to being squeezed and pops out again after the insertion frame 6 is completely inserted, completing the fixation of the insertion frame 6. During disassembly, the upper and lower telescopic blocks 5 are manually pressed back into the telescopic groove 3, and then the insertion frame 6 can be pulled out, thus facilitating the disassembly and assembly of the filter screen 7.

[0027] In addition, the components designed by the utility model are all common standard components or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or through conventional experimental methods. Those skilled in the art can fully implement them without further elaboration. The content protected by the utility model does not involve improvements to the internal structure and method either.

Those of ordinary skill in the art can easily understand the spirit of the utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the utility model, they are within the protection scope of the utility model.
