Technical Field

[0001] The invention relates to the technical field of automobile parts, in particular to a foot-blowing air vent mechanism with air volume adjustment and air door opening and closing functions. Background Art

[0002] The car's foot vents are located at the feet, mainly to utilize the principle of hot air rising and cold air sinking to accelerate the temperature regulation inside the car. This design can quickly increase the temperature inside the car in winter and allow cold air to gradually spread in summer.

[0003] Most of the current foot-blowing air vents are open-type air vent mechanisms. Such traditional open-type foot-blowing air vent mechanisms are prone to foreign objects falling into, which can easily lead to blockage of the air duct, and the air supply volume cannot be adjusted individually, which affects the user experience. Summary of the invention

[0007] A slide rail bracket, wherein the slide rail bracket is fixed to the rear end of the foot-blowing air outlet body;

[0008] A flexible sliding damper is slidably connected to the inside of a slide rail bracket, a heating plate is embedded and fixed on the outer side of the front end of the flexible sliding damper, a damper adjustment switch is clamped in the middle of the front end of the flexible sliding damper, a switch window extends from the front of the damper adjustment switch, and wind windows are provided on both sides of the left and right sides of the front end of the flexible sliding damper.

[0009] Furthermore, the barrier strips are in a "7"-shaped structure, and windows are spaced between adjacent barrier strips, and the wind windows correspond to the windows.

[0010] Furthermore, the four corners between the slide rail bracket and the foot air outlet body are threadedly connected with fastening screws, and foam is provided on both left and right sides of the rear of the slide rail bracket.

[0011] Furthermore, slide rails are fixed on both sides of the left and right sides of the upper and lower ends of the inner wall of the slide rail bracket, the flexible sliding damper is slidably connected between the slide rails, a connecting channel is provided in the middle of the interior of the slide rail bracket, the flexible sliding damper and the connecting channel are interspersed, an installation window is opened in the middle of the front end of the slide rail bracket, the installation window is communicated with the connecting channel, and the front of the damper adjustment switch passes through the installation window.

[0012] Furthermore, a positioning hole is opened in the middle of the front end of the flexible sliding damper, and clamping holes are opened on the upper and lower sides of the middle of the front end of the flexible sliding damper. A positioning column is fixed in the middle of the rear end of the damper adjustment switch, and the positioning column is plugged into the positioning hole. A pair of clamping blocks are symmetrically fixed on the upper and lower sides of the middle of the rear end of the damper adjustment switch, and the clamping blocks are clamped into the clamping holes.

[0013] Furthermore, the heating plate is made of graphene.

[0014] Furthermore, a cross inner cavity is provided inside the damper regulating switch, a push block is slidably connected to the front of the cross inner cavity, the front of the push block extends out of the cross inner cavity, a transverse rack is fixed to the rear end of the push block, a self-locking switch is fixedly installed at the rear end of the cross inner cavity, the rear part of the transverse rack is fixed to the front part of the self-locking switch, and the self-locking switch is electrically connected to the heating plate.

[0015] Furthermore, a tooth column is rotatably connected in the middle of the cross inner cavity, the tooth column is located above the horizontal rack and meshingly connected with the horizontal rack, the front and rear sides of the tooth column are symmetrically meshingly connected with two vertical racks, the vertical rack is located on one side of the horizontal rack, and two top blocks are symmetrically slidably connected on the upper and lower sides of the cross inner cavity, and a rubber block is fixed to the end of the top block away from each other.

[0016] Beneficial effects of the present invention:

[0017] 1. By adding a "7"-shaped blocking strip to the main body of the foot-blowing air outlet, and then setting a flexible sliding air door, the air door adjustment switch can be slid left and right, so that the foot-blowing air door can be completely closed independently when not in use to prevent foreign objects from falling in. When in use, the air door adjustment switch can be used to control the flexible sliding air door to slide left and right to adjust the air volume for air supply, thereby improving user comfort;

[0018] 2. When the user opens the foot-blowing air outlet, if he needs to heat and dry socks or shoes, he can press the button to drive the horizontal rack to move, and the self-locking switch is pressed and self-locked. At this time, the heating plate is energized, and the wind passing through the flexible sliding air door is heated into hot air and then discharged from the air outlet. After that, the user can use the foot-blowing air outlet alone in the car to dry socks or shoes, so that it can be used for multiple purposes;

[0019] 3. When the pressing block drives the horizontal rack to move so that the self-locking switch is pressed and self-locked, the horizontal rack can also engage with the tooth column. In this way, the rotation of the tooth column drives the two vertical racks to move in the opposite direction at the same time. As the vertical racks are separated, the two top blocks are separated. The top block drives the rubber block to support the inner wall of the switch window. At the same time, the rubber block is deformed. This can ensure that the air door adjustment switch is limited to the current position to prevent displacement. Pressing the pressing block again can unlock the self-locking switch, and at the same time the heating piece is powered off, which can close the foot air outlet and improve practicality.
