Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a transmission mechanism for automobile air outlet blades. Background Art

[0002] The car air outlet blades are adjustable components at the air outlet of the car air-conditioning system. By adjusting the angle of the blades, the range of the air outlet can be controlled. Adjusting the blades to a more concentrated angle can make the wind blow to a specific area. When the driver operates the adjustment knob, this action will be transmitted to other components in the transmission mechanism through the connecting rod, such as the gear set and cam mechanism. These components will convert the motion into rotational motion of the blade shaft, thereby changing the angle and direction of the blades. Car air outlets are usually directly exposed to the outside. After a long time, a lot of dust will accumulate on its surface. This dust can easily enter the car's air circulation system with the air outlet of the air conditioner, thereby causing the air quality in the car to drop significantly. Utility Model Content

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 2 to 6 , which is the first embodiment of the present utility model, provides a transmission mechanism for automobile air outlet blades. The transmission mechanism for automobile air outlet blades includes a protective component 200, a positioning component 300 and a main body component 100. The cooperation of the three can provide good protection for the air outlet and prevent the blades from being contaminated by dust.

[0030] The protection assembly 200 includes a protection member 201, including a protection plate 201a, a support shaft 201b and a first torsion spring 201c. The support shaft 201b is inserted into the protection plate 201a, the first torsion spring 201c is sleeved on the outside of the support shaft 201b, and the first torsion spring 201c is fixed to the inner wall of the protection plate 201a.

[0031] By closing the protective plate 201a, the blades 102 in the air outlet frame 101 can be protected to prevent dust from contaminating the blades 102. When the protective plate 201a moves, it will drive the support shaft 201b to rotate. The first torsion spring 201c is fixed to the inner wall of the air outlet frame 101. When the support shaft 201b rotates, it can apply a torsional force to the first torsion spring 201c. When the protective plate 201a needs to be opened, the protective plate 201a can be opened by the force of the rotation of the first torsion spring 201c, so that the air outlet frame 101 can discharge air normally.

[0032] The positioning assembly 300 is arranged at one end of the support shaft 201b, and includes a positioning member 301, including a movable disk 301a, a protrusion 301b and a stopper 301c. The movable disk 301a is fixed to one end of the support shaft 201b, the protrusion 301b is fixed to the top of the movable disk 301a, and the stopper 301c is located at the top of the protrusion 301b.

[0033] When the protective plate 201a is opened and drives the support shaft 201b to rotate, the movable disk 301a will be driven to rotate, and the rotation of the movable disk 301a can drive the protrusion 301b to rotate. At this time, the protrusion 301b can be limited by the setting of the stop block 301c, so that the protective plate 201a is opened to ninety degrees. When the protective plate 201a needs to be fully opened, the stop block 301c is moved. At this time, the limit of the protrusion 301b can be released, and the protective plate 201a can be fully opened when opened. In different usage scenarios, the dustproof requirements are also different. When the protective plate 201a is opened to ninety degrees, it can block dust from entering the air outlet to a certain extent, while ensuring a certain amount of air circulation. When the protective plate 201a is fully opened, a large amount of air exchange can be carried out while reasonable airflow guidance is used to reduce the possibility of dust entering the car.

[0034] Example 2

[0035] Reference Figures 2 to 6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the protection assembly 200 further includes a limiter 202, which is disposed on the support shaft 201b. A ratchet 202a is fixed to one end of the support shaft 201b, and a pawl 202b is disposed on one side of the ratchet 202a. The ratchet 202a and the pawl 202b are engaged with each other.

[0037] When the protective plate 201a is closed, the support shaft 201b will be driven to rotate, and the rotation of the support shaft 201b will drive the ratchet 202a to rotate. When the protective plate 201a is released, the ratchet 202a can be limited by the setting of the pawl 202b, thereby preventing the force of the first torsion spring 201c from rotating and driving the protective plate 201a to open by itself.

[0038] Specifically, a rotating disk 202c is fixed to one side of the pawl 202b, a positioning shaft 202d is inserted into one side of the rotating disk 202c, and the rotating disk 202c and the positioning shaft 202d are rotatably connected via a rotating shaft.

[0039] When the protective plate 201a needs to be opened, the pawl 202b is moved to separate the pawl 202b from the ratchet 202a, thereby releasing the limit on the protective plate 201a, and then the protective plate 201a is driven to open by the rotation force of the first torsion spring 201c.

[0040] When the pawl 202b moves, it can drive the turntable 202c to rotate on the positioning shaft 202d, thereby supporting the pawl 202b and preventing the pawl 202b from shifting. The positioning shaft 202d is fixed to one side of the air outlet frame 101, and the turntable 202c can be supported by the setting of the positioning shaft 202d.

[0041] Specifically, a second torsion spring 202e is sleeved on the outer side of the positioning shaft 202d, and the second torsion spring 202e is fixed to one side of the rotating disk 202c.

[0042] When the pawl 202b is moved and separated from the ratchet 202a, a twisting force can be applied to the second torsion spring 202e. When the pawl 202b is released, the rotational force of the second torsion spring 202e can drive the pawl 202b to return to its original position and re-engage the pawl 202b for next use.

[0043] Specifically, a moving rod 202f is fixed to one end of the pawl 202b, a shift block 202g is fixed to one end of the moving rod 202f, a protective shell 202h is provided on the outer side of the moving rod 202f, and the protective shell 202h and the moving rod 202f are movably connected.

[0044] By moving the shift block 202g, the moving rod 202f will be driven to move, and the moving rod 202f can drive the pawl 202b to move and separate from the ratchet 202a. The protective shell 202h is fixed to one side of the air outlet frame 101. The setting of the protective shell 202h can protect the pawl 202b and the ratchet 202a.

[0045] Specifically, the positioning assembly 300 further includes a moving member 302, which is arranged on the stopper 301c. A support frame 302a is sleeved on the outside of the stopper 301c. The support frame 302a and the stopper 301c are hinged. A moving column 302b is fixed on the top of the support frame 302a.

[0046] A leakage groove is provided on one side of the support frame 302a. When the protective plate 201a is closed, the protrusion 301b is driven to rotate. At this time, the protrusion 301b can squeeze the stopper 301c to make it move. The stopper 301c can move in the leakage groove. At this time, the protrusion 301b will not be limited, so that the protective plate 201a can be closed normally. A reset torsion spring is fixed on one side of the stopper 301c. The reset torsion spring is fixed to the inner wall of the support frame 302a. When the stopper 301c moves, it will apply a torsional force to the reset torsion spring. When 301b moves and separates from the stopper 301c to release the squeeze on the stopper 301c, the force of the reset torsion spring can drive the stopper 301c to return to its original position for next use. When the protective plate 201a needs to be fully opened, the movable column 302b is moved, and the movable column 302b drives the support frame 302a to move, thereby driving the stopper 301c to move and make it rise. At this time, the limit on the protrusion 301b can be released, so that the protective plate 201a can be fully opened.

[0047] Specifically, a support plate 302c is sleeved on the outer side of the movable column 302b, and a spring 302d is fixed on the top of the support plate 302c.

[0048] When the movable column 302b is moved, the support plate 302c can be driven to move. The movement of the support plate 302c can apply a squeezing force to the spring 302d. When the movable column 302b is released, the rebound force of the spring 302d can drive the stopper 301c to return to its original position.

[0049] Example 3

[0050] Reference Figures 1 to 6 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0051] Specifically, a support sleeve 302e is provided on the outer side of the moving column 302b, and the support sleeve 302e and the moving column 302b are movably connected. A moving block 302f is fixed on the top of the moving column 302b, and a protective frame 302g is provided on the outer side of the support sleeve 302e.

[0052] The support sleeve 302e is used to support the moving column 302b to prevent the moving column 302b from shifting. The setting of the moving block 302f facilitates the user to move the moving column 302b. The protective frame 302g is sleeved on the outside of the moving column 302b. The protective frame 302g is movably connected to the moving column 302b. The setting of the protective frame 302g can protect the block 301c.

[0053] Specifically, it also includes a main body component 100, which is arranged on the support shaft 201b, including an air outlet frame 101 and blades 102. The air outlet frame 101 is sleeved on the outside of the support shaft 201b, and the air outlet frame 101 and the support shaft 201b are rotatably connected through a rotating shaft, and the blades 102 are hinged inside the air outlet frame 101.

[0054] By adjusting the angle of the blades 102, the range of the air outlet can be controlled. By adjusting the blades 102 to a more concentrated angle, the wind can be concentrated on a specific area. The air outlet frame 101 is used to support the blades 102 to prevent the blades 102 from shifting. The blades 102 are connected to the air outlet frame 101 through a rotating shaft. The rotating shaft is a cylindrical metal part, and the blades 102 rotate around it, thereby changing the direction of the air outlet.

[0055] Specifically, an adjustment disk 103 is provided on one side of the air outlet frame 101 .

[0056] A gear is set at a specific position of the adjusting disk 103, and a gear meshing with it is also installed at the connection part of the blade 102. When the adjusting disk 103 rotates, the gear on its edge drives the gear on the blade 102 to rotate, thereby changing the angle of the blade 102. The connection method between the adjusting disk 103 and the blade 102 belongs to the existing technology, so it will not be elaborated in detail.

[0057] When in use, the protective plate 201a is closed. When the protective plate 201a moves, it will drive the support shaft 201b to rotate. When the support shaft 201b rotates, it can apply a torsional force to the first torsion spring 201c, and the rotation of the support shaft 201b will drive the ratchet 202a to rotate. The setting of the pawl 202b can limit the ratchet 202a, thereby preventing the force of the rotation of the first torsion spring 201c from driving the protective plate 201a to open by itself. Closing the protective plate 201a can protect the blades 102 in the air outlet frame 101.

[0058] When the protective plate 201a needs to be opened, the movement of the shift block 202g will drive the moving rod 202f to move, and the moving rod 202f can drive the pawl 202b to move and separate from the ratchet 202a. When the pawl 202b is moved and separated from the ratchet 202a, a twisting force can be applied to the second torsion spring 202e. After the pawl 202b moves and separates from the ratchet 202a, the protective plate 201a can be opened by the force of the rotation of the first torsion spring 201c, so that the air outlet frame 101 can discharge air normally. Then release the shift block 202g, and the rotation force of the second torsion spring 202e can drive the pawl 202b to return to its original position and re-engage with the pawl 202b for next use.

[0059] When the protective plate 201a is opened, the movable plate 301a will be driven to rotate, and the rotation of the movable plate 301a can drive the protrusion 301b to rotate. At this time, the protrusion 301b can be limited by the setting of the stop block 301c, so that the protective plate 201a is opened to ninety degrees. When the protective plate 201a needs to be fully opened, the movable block 302f is moved to drive the movable column 302b to move. The movement of the movable column 302b will drive the supporting plate 302c to move. The movement of the support plate 302c can apply a squeezing force to the spring 302d. The movement of the movable column 302b drives the support frame 302a to move, thereby driving the stop block 301c to move and make it rise. At this time, the limit of the protrusion 301b can be released, so that the protective plate 201a can be fully opened. Then release the movable block 302f, and the rebound force of the spring 302d can drive the stop block 301c to return to its original position.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
