A circular air vent structure for automobiles

Abstract

This invention relates to a circular air vent structure for automobiles, comprising a housing structure, an air outlet adjustment structure located at the front end of the housing structure, a damper structure located inside the rear end of the housing structure, and a built-in linkage adjustment structure located inside the housing structure and connected to the air outlet structure and the damper structure. The built-in linkage adjustment structure is connected to a blade ball joint bracket, a front and rear knob linkage structure connected to the blade ball joint bracket, a ball sleeve connection structure located outside the front and rear knob linkage structures, an adjustment gear structure connecting the rear knob linkage structure, and a sleeve bracket structure connecting the ball sleeve connection structure. This structure employs a built-in linkage adjustment structure; the universal joint is eliminated, replaced by one ball joint and two ball sleeves. The outer surface of the ball joint is covered with soft rubber, and the two hard ball sleeves are divided from the center. After the ball sleeves are inserted into the sleeve bracket, they generate a force pressing towards the center of the ball, pressing against the soft rubber of the ball joint to generate an operating force.

Description

Technical Field

[0001] This invention relates to the air vents of automotive dashboards, and more particularly to a circular air vent structure for automobiles. Background Technology

[0002] The automotive air conditioning vent assembly is located in the driver's cabin and is a functional component frequently operated by occupants. When designing the vent structure, it is necessary not only to ensure flexible and convenient operation and meet airflow performance requirements, but also to possess aesthetic appeal and meet appearance requirements. Currently, air vent structures on the market are generally divided into square and round vents, with round vents being particularly popular among consumers due to their unique and attractive design.

[0003] Application No. CN201510150635.4 discloses an automotive air conditioning circular vent assembly, including a housing, a spherical grille, and a damper. The front port of the aforementioned housing is circular, the aforementioned spherical grille is rotatably disposed at the front port of the housing, and the aforementioned damper is disposed inside the housing and can be rotated by a driving mechanism. The driving mechanism is characterized by comprising a crank, an adjusting ring, and a gear set. The crank is rotatably disposed on the outer wall of the aforementioned housing, one end of which is exposed to form a sector gear, and the other end is connected to the aforementioned damper. The adjusting ring is rotatably disposed on the front port of the aforementioned housing, and its inner end has teeth along the annular direction. The gear set is rotatably disposed on the outer wall of the aforementioned housing. The output end of the gear set meshes with the aforementioned sector gear, and the input end meshes with the teeth of the aforementioned adjusting ring.

[0004] Currently, circular air vents mainly generate rotational force by using a universal joint and springs to push against the rotating parts. This results in issues such as blade detachment and inconsistent operating force. Because the springs always push against the blades and generate a consistent operating force, the universal joint's four axes sometimes rotate when operating the blades, and sometimes all four axes rotate.

[0005] In response to the above situation, technological innovations will be carried out based on the existing circular air vent structure of automobiles. Summary of the Invention

[0006] The purpose of this invention is to provide a hot plate welding fixture to solve the problem of blade detachment. Because the spring always presses against the blade and generates a consistent operating force, the universal joint's four shafts sometimes rotate when operating the blade, and sometimes all four shafts rotate.

[0007] The technical solution adopted by this invention to solve its technical problem is: a circular air outlet structure for automobiles, including a housing structure, an air outlet adjustment structure disposed at the front end of the housing structure, a damper structure disposed inside the rear end of the housing structure, and a built-in linkage adjustment structure disposed inside the housing structure and connected to the air outlet structure and the damper structure. The air outlet adjustment structure includes a knob and a blade structure. The damper structure includes a left damper assembly and a right damper assembly. The built-in linkage adjustment structure is connected to the blade ball head bracket, the front and rear knob linkage structure connected to the blade ball head bracket, the ball sleeve connection structure disposed outside the front and rear knob linkage structure and the adjustment gear structure connected to the rear knob linkage structure, and the sleeve bracket structure connected to the ball sleeve connection structure. The built-in linkage adjustment structure is disposed in the housing and connected to the damper structure.

[0008] The blade ball head support includes a ball head body, a cross-shaped connector on the upper part of the ball head body, a ball head limiting block between the cross-shaped connector and the ball head body, and a ball head positioning pin on the outer side of the ball head body.

[0009] The aforementioned front knob linkage structure includes a front insert body and a rear connector body.

[0010] The rear knob linkage structure includes a rear knob linkage body, a connecting platform located on the upper part of the rear knob linkage body, an inner connecting rod located on the upper part of the connecting platform, and a rear knob inner locking member located on the lower part of the rear knob linkage body.

[0011] The adjusting gear structure includes an inner lock seat body connected to the rear-rotating inner locking member, a gear connecting body located at the lower part of the inner lock seat body, and an adjusting gear segment located at the lower part of the gear connecting body, wherein the adjusting gear segment is a bevel gear.

[0012] The ball sleeve connection structure includes a left ball sleeve connection sleeve and a right ball sleeve connection sleeve. Each of the left and right ball sleeve connection sleeves is provided with a spherical cavity. An installation docking groove is provided at the lower part of the left ball sleeve connection sleeve, and an installation docking snap-fit ​​is provided at the lower part of the right ball sleeve connection sleeve. Multiple docking wedges are provided on the outside of the left and right ball sleeve connection sleeves, and each wedge is snap-fitted to the sleeve support structure.

[0013] The sleeve support structure includes an upper docking end connected to the inclined block, a connecting sleeve body located below the upper docking end, and a docking groove provided on the upper docking end.

[0014] The left damper assembly includes a left fan blade body, a left hinge sleeve disposed on the left fan blade body, a left baffle body disposed in the left fan blade body, and a left docking adjustment rack disposed at the lower end of the left hinge sleeve.

[0015] The right damper assembly includes a hollowed-out right fan blade body, a right shaft member located at the side end of the right fan blade body, and a right docking adjustment rack located at the side end of the right shaft member.

[0016] The beneficial effects of this invention are as follows: The structure employs a built-in linkage adjustment mechanism; the universal joint is eliminated, replaced by one ball head and two ball sleeves. The outer surface of the ball head is covered with soft rubber, and the two rigid ball sleeves, separated from the center, exert a squeezing force towards the center of the ball after being inserted into the sleeve support. This squeezing force is applied to the soft rubber of the ball head, generating operating force, resulting in more flexible control, lower resistance, improved component coordination, and extended service life. Furthermore, the diverse appearance treatments greatly enhance its aesthetics.
