Description

Technical Field

[0001] This utility model relates to the field of automotive auxiliary tools technology, and in particular to an extension device for automotive air conditioning vents. Background Technology

[0002] Modern cars are generally equipped with air conditioning systems to provide cooling or heating for the interior. However, some older models only have air conditioning vents near the dashboard at the front of the car. This means that the hot and cold air is mainly concentrated near the front seats, with limited coverage for the rear seats, which affects the overall comfort and satisfaction of the passengers. For example, in some scenarios, after entering the car, users need to quickly cool certain parts of their bodies, a function that the car's air conditioning system cannot provide.

[0003] In existing technologies, although some simple duct designs have emerged to guide airflow from air conditioning outlets, these solutions rely solely on the natural flow of air from the outlets and lack an active airflow mechanism. This results in the airflow weakening easily when passing through long distances or complex paths, ultimately leading to poor performance.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0024] See Figure 1This utility model provides an automotive air conditioning vent extension device, including an vent connector 10 and an air guide duct 20 connected to the vent connector 10. In this utility model, the vent connector 10 is detachably installed on the automotive air conditioning vent and is used to receive airflow from the air conditioning vent. The air guide duct 20 has an inlet end and an outlet end. The inlet end of the air guide duct 20 is connected to the outlet end of the vent connector 10 to guide the airflow received by the vent connector 10 into the interior of the air guide duct 20 and out through the outlet end of the air guide duct 20. It can be a rigid pipe or a flexible, extendable pipe. For example, the air guide pipe 20 is a flexible, extendable pipe (e.g., the air guide pipe can be a corrugated pipe) so that the user can stretch and adjust the direction of the air guide pipe 20 to the target usage position as needed. The material of the air guide pipe 20 can be metal, plastic and rubber. The application scenarios of the car air conditioning vent extension device can be to guide the airflow from the front air conditioning vent of the car to the rear, or to guide the airflow to the part of the human body that needs to be cooled (such as the back) for rapid positioning and cooling, or to guide the airflow to the outdoor camping place (such as the tent).

[0025] In this utility model, see Figure 2 The automotive air conditioning vent extension device further includes an auxiliary suction device 30. The auxiliary suction device 30 is used to assist in drawing airflow from the air conditioning vent into the air duct 20. The auxiliary suction device 30 may include a fan and a pump. The auxiliary suction device 30 may be disposed inside or at the end of the vent connector 10, or inside or at the end of the air duct 20, or as a connector linking the end of the vent connector 10 and the end of the air duct 20. In this invention, to achieve better auxiliary suction effect, the closer the auxiliary suction device 30 is to the air conditioning vent, the better the effect. For example, in this invention, the auxiliary suction device 30 is disposed inside the vent connector 10.

[0026] See Figure 2In an optional embodiment of this utility model, the air inlet end of the air outlet connector 10 is provided with a detachable connection structure. This detachable connection structure allows the air outlet connector 10 to be connected to the car's air conditioning vent during use, and can be detached from the vent when not in use. The detachable connection structure includes a clamping mechanism 40, a magnetic attraction mechanism, and an adhesive structure. The detachable connection structure can be located inside the air inlet of the air outlet connector 10, or around the air inlet of the air outlet connector 10. The magnetic attraction mechanism can be a magnet array or a magnetic ring, and the adhesive structure can be an adhesive layer with release paper.

[0027] See Figure 2 In an optional embodiment of this utility model, the air outlet connector 10 includes a detachably connected front shell 101 and a rear shell 102. The materials of the front shell 101 and the rear shell 102 can be metal or plastic. The detachable connection method of the front shell 101 and the rear shell 102 can include a snap-fit ​​connection and a raised groove connection. Taking the snap-fit ​​connection as an example, a first snap hook lug 1011 and a second snap hook lug are respectively provided on a set of opposite sides of the front shell 101, and a corresponding set of opposite sides of the rear shell 102... The front shell 101 is provided with a first hook hole 1021 and a second hook hole. When connected, the first snap hook ear 1011 and the second snap hook ear of the front shell 101 extend into the interior of the rear shell 102 through the opening of the rear shell 102 and are respectively aligned and engaged with the first hook hole 1021 and the second hook hole. When disassembling, it is only necessary to press the first snap hook ear 1011 and the second snap hook ear to disengage from the first hook hole 1021 and the second hook hole respectively, and then pull the front shell 101 and the rear shell 102 to disassemble.

[0028] See Figure 2 In this utility model, a bracket 50 is provided inside the front shell 101, and the clamping mechanism 40 is mounted on the bracket 50. In this embodiment of the utility model, the air inlet end of the air outlet connector 10 is located on one side of the front shell 101. The purpose of the air outlet connector 10 being divided into the detachable front shell 101 and the rear shell 102 is to facilitate the removal of the rear shell 102 to operate the clamping mechanism 40. In this utility model, in order to ensure that the auxiliary suction device 30 does not affect the user's operation of the clamping mechanism 40, and taking the auxiliary suction device 30 as a fan as an example, the auxiliary suction device 30 is disposed inside the rear shell 102.

[0029] In one optional embodiment of this utility model, the clamping mechanism 40 is slidably disposed on the bracket 50. In this embodiment, the advantage of the slidable clamping mechanism 40 is that the coverage area of ​​the air outlet connector 10 over the car's air conditioning outlet can be flexibly adjusted to distribute the air intake volume of the air outlet connector 10.

[0030] See Figure 3 In an optional embodiment of this utility model, the clamping mechanism 40 includes a first clamping arm 401, a second clamping arm 402, a rotating pin 403, a torsion spring 404, a hinge bolt 405, and a knob 406. The first clamping arm 401 and the second clamping arm 402 are rotatably connected by the rotating pin 403. The torsion spring 404 and the hinge bolt 405 are both sleeved on the rotating pin 403. For example, the torsion spring 404 and the hinge bolt 405 are centrally located on the rotating pin 403. The torsion spring 404 is used to keep the first clamping arm 401 and the second clamping arm 402 in a normally open state.

[0031] See Figure 3 The bracket 50 includes a first crossbeam 501 and a second crossbeam 502 arranged in parallel. The hinge bolt 405 passes through the gap between the first crossbeam 501 and the second crossbeam 502 and is threadedly connected to the knob 406. To prevent the knob 406 from sliding on the first crossbeam 501 and the second crossbeam 502 after it is tightened, a washer 407 is provided between the knob 406 and the first crossbeam 501 and the second crossbeam 502.

[0032] The working principle of the clamping mechanism 40 of this utility model is as follows: rotating the knob 406 pulls the hinge bolt 405. The hinge bolt 405 then drives the tails of the first clamping arm 401 and the second clamping arm 402 on the non-clamping side to move towards the first crossbeam 501 and the second crossbeam 502 through the rotating pin 403. The first crossbeam 501 and the second crossbeam 502 respectively press the tails of the first clamping arm 401 and the second clamping arm 402 on the non-clamping side (the tails of the first clamping arm 401 and the second clamping arm 402 on the non-clamping side are respectively provided with a first step 4011 and a second step 4012 for contact positioning of the first crossbeam 501 and the second crossbeam 502), so that the tails of the first clamping arm 401 and the second clamping arm 402 on the non-clamping side overcome the elastic force of the torsion spring 404 and rotate around the rotating pin 403, thereby causing the clamping side of the first clamping arm 401 and the second clamping arm 402, which is normally open, to close. See [link to relevant documentation]. Figure 3In order to improve the stability of the first clamping arm 401 and the second clamping arm 402 when clamped on the car air conditioning vent, the first clamping arm 401 and the second clamping arm 402 are symmetrically provided with support ears 408, and buffer pads 409 are provided on the clamping contact surfaces of the first clamping arm 401 and the second clamping arm 402.

[0033] See Figure 2 In one optional embodiment of this utility model, a silicone cover 60 is provided on the side of the front shell 101 facing the car air conditioning vent. The silicone cover 60 serves two purposes: firstly, it expands the diameter of the air inlet of the air outlet connector 10; secondly, the flexible contact of the silicone cover 60 allows for better fit with the car air conditioning vent. To facilitate the contact expansion and contraction of the silicone cover 60, a corrugated folding mechanism 601 is provided on the silicone cover 60.

[0034] See Figure 2 In an optional embodiment of this utility model, a pipe connector 70 is provided on the side of the rear shell 102 opposite to the front shell 101, and the air inlet end of the air guide duct 20 is detachably connected to the rear shell 102 through the pipe connector 70. In this utility model, the pipe connector 70 includes a threaded pipe section 701 and a nut pipe section 702. The nut pipe section 702 is I-shaped, and the air inlet end of the air guide duct 20 is connected to the nut pipe section 702. See Figure 1 In an optional embodiment of this utility model, a filter 80 is provided at the air outlet of the air duct 20. The filter 80 is used to filter the air outlet of the air duct 20 to improve the cleanliness of the air outlet and eliminate odors. The filter 80 includes a filter screen and an adsorbent material.

[0035] To better illustrate the automotive air conditioning vent extension device of this utility model, an exemplary automotive air conditioning vent extension device of this utility model can be as follows: See Figures 1-3The automotive air conditioning vent extension device includes an vent connector 10, an air duct 20 connected to the vent connector 10, and an auxiliary suction device 30 disposed inside the vent connector 10.
