Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories. More specifically, the utility model relates to an intelligent retractable optical and electronic rearview mirror. Background Art

[0002] An optical and electronic rearview mirror is also called an electronic rearview mirror or a camera monitoring system. Compared with a traditional rearview mirror, this system combines cameras installed outside the vehicle to capture images of the rear or side of the vehicle and transmits these images in real time to a display screen located inside the cab, providing a wider field of view for the driver and improving driving safety.

[0003] In the prior art, in order to protect the electronic rearview mirror of the vehicle from damage, improve the aesthetics and intelligent level of the vehicle, the electronic rearview mirror is designed with a retractable and bendable function, that is, the electronic rearview mirror automatically extends when the vehicle starts to provide a clear field of view, and the electronic rearview mirror automatically retracts when the vehicle shuts down to achieve the protection effect. When the electronic rearview mirror retracts and bends, in order to accurately control the bending angle position, a worm and worm gear meshing is used inside it as a component to drive the rearview mirror to rotate. The worm and worm gear transmission has a self-locking function with high reliability. In order to reduce the friction between the worm and worm gear, a lubricant needs to be applied at the meshing part of the worm and worm gear. The lubricant can form a thin film to isolate the direct contact between the metal surfaces of the worm and worm gear, reduce the particles generated due to wear, and extend the service life of the worm and worm gear.

[0004] However, the prior art cannot automatically add lubricant to the tooth surfaces of the worm and worm gear. Frequent use and high temperature in summer will accelerate the evaporation rate of the lubricant on the tooth surfaces of the worm and worm gear, resulting in insufficient lubrication of the worm and worm gear. When the electronic rearview mirror retracts and bends, it will not only accelerate the wear of the tooth surfaces, but also generate noise when the worm and worm gear mesh, affecting the user experience. Summary of the Utility Model

[0005] The intelligent retractable optical and electronic rearview mirror provided by the utility model aims to solve the following problems: the existing intelligent retractable optical and electronic rearview mirror cannot automatically add lubricant to the tooth surfaces of the worm and worm gear. Frequent use and high temperature in summer will accelerate the evaporation rate of the lubricant on the tooth surfaces of the worm and worm gear, resulting in insufficient lubrication of the worm and worm gear. When the electronic rearview mirror retracts and bends, it will not only accelerate the wear of the tooth surfaces, but also generate noise when the worm and worm gear mesh, affecting the user experience.

Detailed implementation manners

[0026] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0027] At present, there are two kinds of lubricants applied to the worm gears and worm shafts in the optical electronic rearview mirror. One is a relatively thick lubricating grease, and the other is a relatively thin lubricating fluid. The thick lubricating grease may become more viscous at low or high temperatures, affecting its fluidity and uniformity of distribution, so that it cannot effectively cover all surfaces that need to be lubricated, and will increase the frictional resistance during the transmission of the worm gears and worm shafts, resulting in the motor needing more energy to overcome this resistance, thus increasing energy consumption and further failing to achieve a good lubrication effect. Therefore, it is more appropriate to choose the relatively thin lubricating fluid as the lubricant. The relatively thin lubricating fluid has good lubrication performance at extreme temperatures. However, high temperatures in summer or frequent use will accelerate the evaporation and consumption of the relatively thin lubricating fluid. When the lubricating fluid on the surface of the worm gears and worm shafts is consumed, it needs to be replenished in time. When the lubricating fluid on the tooth surfaces of the worm gears and worm shafts is insufficient during meshing, noise and abnormal sounds will be generated, affecting the normal use of the user. At present, the intelligent retractable optical electronic rearview mirror cannot automatically add lubricating fluid to the tooth surfaces of the worm gears and worm shafts, and there are great limitations in use. To solve the above problems, this application refers to the attached drawings of the specification Figures 1 to 7 A kind of intelligent retractable optical electronic rearview mirror, which includes a mounting plate 1. A camera module 11 is arranged on the mounting plate 1. A housing 2 is rotatably arranged on the mounting plate 1. A rearview mirror glass 21 is fixedly arranged on the housing 2. A turn signal lamp 22 is also arranged on the housing 2;

[0028] A bending and telescoping mechanism 3 is arranged inside the housing 2. The bending and telescoping mechanism 3 includes a support base 32. The support base 32 is rotatably arranged with the mounting plate 1, and the housing 2 is fixedly arranged with the support base 32;

[0029] A driving mechanism 4 is arranged inside the mounting plate 1. The driving mechanism 4 includes a worm 41 and a worm gear 42. The worm 41 is engaged with the worm gear 42. The worm gear 42 is used to drive the support base 32 to rotate. A storage box 44 is fixedly arranged inside the mounting plate 1. A rolling ball 442 is arranged to roll inside the storage box 44. The inside of the storage box 44 is set as a storage area, and a lubricant is stored in the storage area. The rolling ball 442 is in contact with the lubricant in the storage area, and the rolling ball 442 is arranged to roll on the upper surface of the worm gear 42.

[0030] It should be noted that the lubricant is selected as the relatively thin lubricating fluid. The camera module 11 is set as a high-definition camera. Collecting images through the high-definition camera and then displaying the images collected by the high-definition camera on the display screen in the vehicle is a mature existing technology, so no more details will be described.

[0031] The specific implementation scenario is as follows: when the vehicle is turned off, the outer shell 2 will rotate and retract, and when the vehicle is started, the outer shell 2 will rotate and extend. The specific implementation method is that first, the worm 41 is driven to rotate. The worm 41 meshes with the worm wheel 42 to drive the worm wheel 42 to rotate. The rotation of the worm wheel 42 then drives the outer shell 2 to rotate. Since there is lubricant stored in the storage area of the storage box 44, under the action of gravity, the part of the ball 442 located in the storage box 44 is immersed in the lubricant. The ball 442 is rotatably arranged with the worm wheel 42. When the worm wheel 42 rotates, it will drive the ball 442 to roll on the worm wheel 42. When the ball 442 rolls, it can smear the lubricant attached to its surface on the surface of the worm wheel 42. Under the action of gravity, the lubricant will flow along the tooth surface of the worm wheel 42, filling the tooth surface of the worm wheel 42. When the worm 41 meshes with the worm wheel 42, the lubricant can achieve a good lubrication effect.

[0032] Refer to the attached drawings of the specification Figures 1 to 3 In the rainy days, the rain will wet the rearview mirror glass 21. In order to quickly remove the water stains on the rearview mirror glass 21, specifically, the bending and telescoping mechanism 3 includes a rotating seat 31. The bottom of the rotating seat 31 is rotatably provided with a connecting plate 311. The connecting plate 311 is fixedly provided with the mounting plate 1. The support seat 32 is fixedly provided on the rotating seat 31, and a heating coil 33 is fixedly provided on the support seat 32.

[0033] It should be noted that the heating coil 33 can convert electrical energy into heat energy. As a mature existing technology, it will not be elaborated here too much.

[0034] It should also be noted that when the rain wets the rearview mirror glass 21, the heating coil 33 is turned on through the control switch in the vehicle. The increase in the temperature of the heating coil 33 transfers the temperature to the rearview mirror glass 21. After the temperature of the rearview mirror glass 21 increases, it can accelerate the evaporation of the water on its surface.

[0035] Refer to the attached drawings of the specification Figures 1 to 4 In order to be able to drive the worm 41 to rotate stably, specifically, the driving mechanism 4 includes a rotating driver 43. The rotating driver 43 is fixedly provided in the mounting plate 1, and the worm 41 is fixedly provided on the output shaft of the rotating driver 43.

[0036] It should be noted that the rotating driver 43 is set as a motor. The motor is fixedly provided in the mounting plate 1, and the worm 41 is fixedly provided with the output shaft of the motor.

[0037] It should also be noted that when the rotating driver 43 is started, the rotation of the output shaft of the rotating driver 43 drives the worm 41 to rotate. The worm 41 meshes with the worm wheel 42 to drive the rotating seat 31 to rotate.

[0038] Refer to the attached drawings of the specification Figures 1 to 4, when the housing 2 is folded, in order to be able to drive the housing 2 to rotate stably. Specifically, a transmission shaft is rotatably arranged in the mounting plate 1, the worm gear 42 is fixedly sleeved on the transmission shaft, and the rotating seat 31 is fixedly arranged with the transmission shaft.

[0039] It should be noted that the worm 41 meshes with the worm gear 42 to drive the worm gear 42 to rotate. The rotation of the worm gear 42 drives the transmission shaft to rotate, and the transmission shaft then drives the rotating seat 31 to rotate.

[0040] Refer to the attached instructions Figures 1 to 5 , as the lubricant in the storage area will become less and less with continuous use. In order to ensure sufficient contact between the lubricant in the storage area and the rolling balls 442, specifically, a push plate 441 is slidably arranged in the storage box 44, and an elastic member 443 is fixedly arranged between the push plate 441 and the storage box 44.

[0041] It should be noted that the elastic member 443 is set as a spring. The spring tube is fixedly arranged with the push plate 441, and one end of the elastic member 443 away from the push plate 441 is fixedly arranged with the inner wall of the storage box 44.

[0042] It also should be noted that the storage area is located between the push plate 441 and the rolling balls 442. As the lubricant in the storage area decreases, under the action of the elastic force of the elastic member 443, it can ensure that the push plate 441 always contacts the liquid level of the lubricant in the storage area, so as to ensure sufficient contact between the lubricant and the rolling balls 442.

[0043] Refer to the attached instructions Figure 7 , when the lubricant in the storage area is exhausted, in order to facilitate replenishing the lubricant in the storage area for the user to continue using, specifically, a transparent tube 445 is fixedly communicated with the push plate 441. A tube cap is threadedly installed at the top of the transparent tube 445. A pull rope 444 is fixedly arranged on the push plate 441, and a feed pipe is fixedly communicated with the storage box 44.

[0044] It should be noted that first, pull up the pull rope 444. The movement of the pull rope 444 drives the push plate 441 to move upward in the storage box 44. At this time, the elastic member 443 is compressed. Remove the tube cap on the transparent tube 445, then connect a delivery pipe to the feed pipe, and add lubricant to the storage area through the delivery pipe and the feed pipe. As the lubricant in the storage area increases, the air in the storage area will be discharged through the transparent tube 445. When the storage area is full of lubricant, it will flow upward through the transparent tube 445. Then remove the delivery pipe and install the tube cap on the transparent tube 445.

[0045] Refer to the attached instructions Figures 5 to 7 , after the lubricant covers the surface of the worm gear 42, in order to enable the lubricant to flow efficiently to the tooth surface of the worm gear 42, specifically, a guide plate 421 is fixedly arranged on the worm gear 42, and a guide groove 422 is opened on the guide plate 421.

[0046] It should be noted that the lubricant stays on the surface of the deflector plate 421 and flows to the tooth surface of the worm gear 42 under the guiding action of the guiding groove 422, which is convenient for the engagement of the worm 41 and the worm gear 42 and enhances the lubrication effect. The above embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
