Description

Technical Field

[0001] This utility model relates to the field of mechanical power equipment technology, and more specifically, to an active air intake grille inner and outer blade connection structure. Background Technology

[0002] As the automotive industry continues to develop towards intelligence and energy efficiency, the active air intake grille, as a key component for regulating engine compartment heat dissipation efficiency and optimizing vehicle aerodynamic performance, has received widespread attention for its technical performance. Currently, the connection between the inner and outer blades of the active air intake grille is mostly achieved by bolt fixing. During vehicle operation, the inner and outer blades of the active air intake grille typically need to undergo frequent opening and closing movements. Under repeated stress changes, the bolt connection points will experience vibration and stress concentration. Under frequent vibration and stress concentration, the bolts may loosen, thus affecting the normal operation of the active air intake grille. To address this, an active air intake grille inner and outer blade connection structure has been designed. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides an active air intake grille inner and outer blade connection structure, which has the advantages of quick and stable installation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an active air intake grille inner and outer blade connection structure, including an inner blade, an outer blade sleeved on the outer wall of the inner blade, a limiting plate fixedly connected to the top of the outer blade, a positioning rib fixedly connected to the inner wall of the limiting plate, an extension plate fixedly connected to the bottom of the inner blade, and a snap-fit ​​plate fixedly connected to the bottom of the outer blade, the inner wall of the snap-fit ​​plate being snap-fitted to the outer wall of the extension plate.

[0005] As a preferred embodiment of this utility model, the outer wall of the inner leaf plate and the end located near the outer leaf plate are fixedly connected with a number of reinforcing ribs.

[0006] As a preferred embodiment of this utility model, a fixed horizontal plate is fixedly connected to the top of the inner leaf plate, and the inner wall of the limiting plate is sleeved with the outer wall of the fixed horizontal plate.

[0007] In a preferred embodiment of this utility model, the outer wall of the positioning rib is sleeved with the inner wall of the fixing cross plate.

[0008] As a preferred embodiment of the present invention, a partition plate 1 is fixedly connected to the outer wall of the inner blade plate at one end away from the outer blade plate, and a partition plate 2 is fixedly connected to the outer wall of the inner blade plate at one end away from the partition plate 1.

[0009] As a preferred embodiment of this utility model, a rotating shaft is fixedly connected to the outer wall of the first partition, and a positioning shaft is fixedly connected to the outer wall of the second partition.

[0010] As a preferred technical solution of this utility model, a drive shaft is fixedly connected to the outer wall of the partition plate two at the end near the positioning shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a limiting plate and a snap-fit ​​plate at the top and bottom of the outer leaf plate. The snap-fit ​​fixing method of the limiting plate and the snap-fit ​​plate replaces the bolt fixing, thereby stabilizing the connection between the inner leaf plate and the outer leaf plate. The limiting plate at the top of the outer plate limits the top of the inner leaf plate. The extension plate is snapped to the inner wall of the snap-fit ​​plate by flipping and pressing, thereby effectively fixing the inner leaf plate to the inner wall of the outer leaf plate. Compared with bolts, the installation and fixing process is more convenient, and the inner leaf plate and the outer leaf plate can be quickly and stably installed.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 5 As shown, this utility model provides an active air intake grille inner and outer blade connection structure, including an inner blade 1, an outer blade 2 sleeved on the outer wall of the inner blade 1, a limiting plate 201 fixedly connected to the top of the outer blade 2, a positioning rib 202 fixedly connected to the inner wall of the limiting plate 201, an extension plate 301 fixedly connected to the bottom of the inner blade 1, and a snap-fit ​​plate 203 fixedly connected to the bottom of the outer blade 2, with the inner wall of the snap-fit ​​plate 203 snap-fitted to the outer wall of the extension plate 301.

[0017] Among them, the outer wall of the inner leaf plate 1 and the end located near the outer leaf plate 2 are fixedly connected with several reinforcing ribs 101.

[0018] It should be noted that the reinforcing rib 101 is in the shape of a transverse partition. Multiple reinforcing ribs 101 are transversely fixed on one side of the outer surface of the inner blade plate 1. After the inner blade plate 1 and the outer blade plate 2 are installed, the reinforcing rib 101 will support the inner blade plate 1 and the outer blade plate 2. Through the support of the reinforcing rib, the inner blade plate is effectively prevented from deforming due to frequent opening and closing of the blades or impact of high-speed airflow.

[0019] Among them, the top of the inner leaf plate 1 is fixedly connected to the fixed horizontal plate 3, the inner wall of the limiting plate 201 is sleeved with the outer wall of the fixed horizontal plate 3, and the outer wall of the positioning rib 202 is sleeved with the inner wall of the fixed horizontal plate 3.

[0020] It should be noted that the fixed horizontal plate 3 is fixedly connected to the top of the inner leaf plate 1. The top of the inner leaf plate 1 has a groove in the middle. When installing the inner leaf plate 1 and the outer leaf plate 2, the fixed horizontal plate 3 at the top of the inner leaf plate 1 needs to be sleeved on the inner wall of the limiting plate 201. During the sleeve process, the groove needs to be sleeved on the outer wall of the positioning rib 202 for positioning. The positioning rib 202 is used to make the inner leaf plate 1 straight installed on the inner wall of the outer leaf plate 2.

[0021] Among them, a partition 4 is fixedly connected to the outer wall of the inner blade plate 1 at the end that is away from the outer blade plate 2, and a partition 401 is fixedly connected to the outer wall of the inner blade plate 1 at the end that is away from the partition 4.

[0022] A rotating shaft 404 is fixedly connected to the outer wall of partition 1 4, a positioning shaft 403 is fixedly connected to the outer wall of partition 2 401, and a drive shaft 402 is fixedly connected to the outer wall of partition 2 401 at the end near the positioning shaft 403.

[0023] It should be noted that partition 4 is fixedly installed on one side of inner leaf plate 1, and partition 401 is fixedly connected to the other side of inner leaf plate 1. Both positioning shaft 403 and rotating shaft 404 need to be rotatably connected to the inner wall of the bearing seat on the inner wall of the frame. Positioning shaft 403 and rotating shaft 404 are kept at the same horizontal position. The outer wall of drive shaft 402 is rotatably connected to one end of driven connecting rod. When the motor starts, the motor drives the driven connecting rod to rotate through the output end. At the same time, the driven connecting rod drives drive shaft 402 to rotate synchronously. Then, drive shaft 402 drives inner leaf plate 1 and outer leaf plate 2 to rotate in linkage through partition 401. Inner leaf plate 1 will rotate around the horizontal position of positioning shaft 403 and rotating shaft 404 as the center, realizing the effect of active opening and closing of air intake grille.

[0024] Working principle and usage process of this utility model: The specific operation is as follows: When connecting the inner leaf plate 1 and the outer leaf plate 2, the operator needs to fit the fixed horizontal plate 3 at the top of the inner leaf plate 1 onto the inner wall of the limiting plate 201. During the fitting process, the middle of the top of the fixed horizontal plate 3 needs to be fitted onto the outer wall of the positioning rib 202. The positioning rib 202 is used to position the installation of the inner leaf plate 1. After the fixed horizontal plate 3 and the limiting plate 201 are connected, one end of the extension plate 301 of the inner leaf plate 1 needs to be pressed. Under the restriction of the limiting plate 201, the inner leaf plate 1 will rotate around the connection point between the limiting plate 201 and the fixed horizontal plate 3. When rotating, the reinforcing rib 101 on one side of the inner leaf plate 1 will support the inner wall of the outer leaf plate 2. The extension plate 301 at the bottom of the inner leaf plate 1 needs to be flipped and snapped into place. The inner wall of plate 203, under the mutual restraint of buckle plate 203 and limit plate 201, fixes the inner blade plate 1 to the inner wall of outer blade plate 2. At this time, if the motor starts, it drives the drive shaft and connecting rod to rotate. The drive shaft and connecting rod drive the drive shaft 402 to perform circumferential motion. The drive shaft 402 then drives the inner blade plate 1 and outer blade plate 2 to flip through partition plate 2 401. During the flipping process, the inner blade plate 1 and outer blade plate 2 drive the rotating shaft 404 and positioning shaft 403 to rotate. The inner blade plate 1 and outer blade plate 2 will flip around the horizontal line of rotating shaft 404 and positioning shaft 403 as the center, realizing the effect of active opening and closing of air intake grille, and using rotating shaft 404 and positioning shaft 403 to stabilize the flipping of inner blade plate 1 and outer blade plate 2.
