Technical Field
[0001] This utility model relates to the field of rearview mirror housing technology, and in particular to a rearview mirror housing with noise reduction function. Background Technology
[0002] Car noise is mainly caused by wind noise, which has a variety of causes, including rearview mirrors. The rearview mirrors are positioned close to the driver's position, which makes the noise from the rearview mirrors more noticeable to the driver. Therefore, reducing wind noise from the rearview mirrors is a very important aspect of improving the driving comfort of customers.
[0003] Existing technologies, such as Chinese Patent Publication No. CN213594184U, disclose a noise-reducing rearview mirror, including a decorative cover, a lower mirror housing, felt, arc-shaped airflow guide ribs, and a support cover. The support cover is installed on the outer panel of the door and is used to connect the rearview mirror assembly and the vehicle body. The decorative cover is connected and installed together with the lower mirror housing. A part of the support cover is connected to the lower mirror housing, and another part is connected to the decorative cover. Several arc-shaped airflow guide ribs are provided on the top of the decorative cover. The felt is installed in the gap between the decorative cover, the lower mirror housing, and the support cover. The decorative cover has a structure that is low at the front and high at the rear. The windward side of the decorative cover is low, and along the airflow direction, it rises from low to high. The decorative cover rises from the part away from the mirror ring to the part closer to the mirror ring. The decorative cover can effectively delay surface boundary layer separation and reduce the intensity of vortices at the rear of the rearview mirror. The arc-shaped airflow guide ribs have the effect of rectifying and guiding airflow, directing the vortex at the rearview mirror away from the side window, reducing the effect of the rearview mirror tail vortex on the front side window surface, and thus reducing noise. However, the arc-shaped airflow guide ribs of this utility model are fixed, making it inconvenient to install, remove, and adjust according to noise reduction needs and actual driving conditions.
[0004] To address the issue that rearview mirror housings are not easily adjustable to reduce noise according to needs and actual conditions, most existing technologies use fixed-position spoiler structures for noise reduction. However, these structures are not easy to install, remove, or adjust, and their adaptability to complex driving environments is generally limited. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to solve the problem that existing rearview mirror housings are not convenient for adjusting the turbulence structure to achieve noise reduction as needed and in accordance with actual conditions, and to propose a rearview mirror housing with noise reduction function.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rearview mirror housing with noise reduction function, comprising a housing, an opening and a noise reduction mechanism, wherein the opening is formed on the surface of the housing and the noise reduction mechanism is disposed on the surface of the housing;
[0007] The noise reduction mechanism includes a turbulence component, a loading and unloading component, and an auxiliary component. The turbulence component includes a receiving groove, which is formed on the surface of the housing. A motor is fixedly installed on the surface of the receiving groove. A screw is fixedly connected to the output end of the motor. A mounting plate is threadedly connected to the surface of the screw. The mounting plate is slidably connected to the surface of the receiving groove. A turbulence plate is provided on the surface of the mounting plate, and a turbulence groove is formed on the surface of the turbulence plate.
[0008] The loading and unloading assembly includes a clamping plate, which is slidably connected to the inner wall of the mounting plate. The surface of the spoiler is provided with a slot, and a spring is fixedly connected to the surface of the clamping plate. The spring is fixedly connected to the inner wall of the mounting plate.
[0009] Furthermore, the card plate is engaged with the surface of the card slot, the surface of the mounting plate is provided with a guide groove, and the spoiler is slidably connected to the surface of the guide groove.
[0010] Furthermore, the number of the card plate, card slot, spring and guide groove are all two sets, and the surface of the card plate is provided with an arc surface.
[0011] Furthermore, the number of the turbulence channels is multiple and evenly distributed, and the turbulence plates are provided with different specifications.
[0012] Furthermore, the auxiliary component includes a guide rod, which is fixedly connected to the surface of the receiving groove, and the mounting plate is slidably connected to the surface of the guide rod.
[0013] Furthermore, an anti-detachment disc is fixedly connected to the surface of the guide rod, and an anti-detachment groove is provided on the inner wall of the mounting plate. The anti-detachment disc is slidably connected to the surface of the anti-detachment groove.
[0014] Furthermore, a sealing ring one and a sealing ring two are fixedly connected to the surface of the mounting plate.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. In this utility model, by setting a noise reduction mechanism, the turbulence groove on the turbulence plate at the opening end is used to reduce the intensity and size of the wake at the rear of the shell, thereby reducing the aerodynamic noise generated by the shell. The motor is started to rotate the screw, which in turn causes the mounting plate to slide along the receiving groove, thereby adjusting the position of the turbulence plate. The turbulence plate is provided with different specifications, and turbulence plates with different turbulence grooves or without turbulence grooves can be installed as needed. Simply move the mounting plate to the limit position to expose the slot, press down the two sets of locking plates to disengage them from the slots and compress the springs, and the turbulence plate can be removed. During installation, the guide groove is used to ensure quick alignment. Under the action of the arc surface, the turbulence plate can directly push the locking plate into the inner wall of the mounting plate and compress the springs. After the turbulence plate is installed in place, the locking plate is reset under the action of the spring rebound and is locked into the slots for fixation.
[0017] 2. In this utility model, by setting a noise reduction mechanism and using a spoiler at the opening end, the intensity of the wake and the size of the wake area at the rear of the shell are reduced, thereby achieving a noise reduction effect. The position of the spoiler can be adjusted or the spoiler can be installed, removed or replaced as needed and according to actual conditions, which effectively improves the applicability of the equipment.

The spoiler 315 is provided with different specifications, and spoilers 315 with different aerodynamic grooves 316 or without aerodynamic grooves 316 can be installed as needed. 5. Simply move the mounting plate 314 to its limit position to expose the slot 322, press down the two sets of locking plates 321 to disengage them from the slot 322 and compress the spring 323 to remove the spoiler 315. During installation, the guide groove 324 ensures quick alignment. Under the action of the arc surface 325, the spoiler 315 can directly push the locking plate 321 into the inner wall of the mounting plate 314 and compress the spring 323. After the spoiler 315 is installed in place, the locking plate 321 returns to its original position under the rebound action of the spring 323 and is locked into the slot 322 for fixation.
[0043] By setting a noise reduction mechanism 3 and using a spoiler 315 at the opening 2, the intensity of the wake and the size of the wake area at the rear of the housing 1 are reduced, thereby achieving a noise reduction effect. The position of the spoiler 315 can be adjusted or the spoiler 315 can be installed, removed or replaced as needed and according to actual conditions, which effectively improves the applicability of the equipment.
