Technical Field
[0001] This utility model relates to the field of optical application technology, specifically to an optical component installed on a car rearview mirror. Background Technology
[0002] In urban road traffic, the frequency of use of private cars is increasing. However, when large trucks appear in front of the vehicle, various obstructions to visibility are often encountered. For left-hand drive vehicles, obstruction of the right front is a common problem. The large size of the truck will seriously obstruct the view of the driver of the car behind, such as making it impossible to directly observe the status of traffic lights. In this situation, the driver often finds it difficult to accurately judge when to change lanes, when to proceed, and when to stop and wait. This not only reduces driving efficiency but may also cause traffic accidents due to misjudgment, threatening the life and property safety of himself and other road users.
[0003] Currently, car rearview mirrors are mainly used to observe the situation behind the vehicle, and traditional rearview mirrors have relatively limited functions. Although there are some driver assistance devices on the market, there are few products specifically designed to solve the problem of large trucks obstructing the view and making it impossible to observe the road conditions ahead. Existing devices are either functionally incompatible or too expensive, making them difficult to widely apply to ordinary family cars. In order to improve driving safety and convenience, we have developed a forward-looking optical component that can be installed on a car rearview mirror. Through the movable design of the optical camera, it provides drivers with a new way to observe the road conditions ahead (such as observing traffic lights), effectively addressing this common driving dilemma. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an optical component installed in a car rearview mirror to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an optical component installed in a car rearview mirror, including a rearview mirror, wherein a sliding block is slidably installed inside the rearview mirror, and the shape of the outer end face of the sliding block is the same as the shape of the outer wall of the rearview mirror;
[0006] The outer wall of the sliding block is equipped with an optical camera for taking pictures, and a protective lens for protecting the optical camera is installed on the outer wall of the sliding block. In addition, a guide groove is opened on the outer wall of the sliding block to reduce the wind resistance of the sliding block.
[0007] The rearview mirror is equipped with a drive mechanism connected to a sliding block. When the drive mechanism is running, it pushes the sliding block out of the rearview mirror to expose the optical camera.
[0008] By adopting the above technical solution, the problem of drivers being unable to observe traffic lights when passing through intersections due to obstructed views by large trucks in front can be effectively solved. This helps drivers accurately judge the status of traffic lights, improves driving safety, reduces traffic accidents caused by misjudgment, and protects the lives and property of drivers and other road users.
[0009] Furthermore, the outer wall of the rearview mirror is provided with a mounting groove corresponding to the sliding block.
[0010] By adopting the above technical solution, the mounting groove will support the sliding block and improve the stability of the sliding block.
[0011] Furthermore, the outer corners of the sliding block are all designed with rounded corners, and the outer wall of the end of the sliding block is provided with a sealing gasket that fits against the inner wall of the mounting groove.
[0012] By adopting the above technical solution, the arc-shaped rounded corners can further reduce the impact of airflow on the sliding block.
[0013] Furthermore, the protective lens is entirely located within the flow guide groove, and both the upper and lower end faces of the flow guide groove and the end face of the protective lens are designed with arc surfaces.
[0014] By adopting the above technical solutions, the protective lens and the guide channel will guide the airflow, reduce the impact of the airflow on the sliding block, and further extend the service life of the sliding block.
[0015] Furthermore, the driving mechanism is an electric actuator connected to the sliding block, and a mounting bracket connected to the electric actuator is installed inside the rearview mirror.
[0016] By adopting the above technical solution, the movement of the sliding block can be flexibly controlled, ensuring that the optical camera can be smoothly moved out of the rearview mirror when information needs to be collected.
[0017] Furthermore, a cross groove is provided at the inner end of the sliding block, and the outer wall of the cross groove is fixedly connected to the end of the electric push rod.
[0018] By adopting the above technical solution, the sliding length of the sliding block can be maximized within the limited space inside the rearview mirror.
[0019] Furthermore, the outer wall of the sliding block is detachably fitted with an extension plate, and the corners of the extension plate are in contact with the mounting groove during the outward sliding of the sliding block.
[0020] By adopting the above technical solution, the length that the sliding block can slide out is further increased, further ensuring that the optical camera can successfully capture the traffic light situation.
[0021] In summary, the present invention has the following main advantages:
[0022] This invention effectively solves the problem of drivers being unable to observe traffic lights when approaching intersections due to obstructed views by large trucks. It assists drivers in accurately judging traffic light status, improving driving safety, reducing traffic accidents caused by misjudgment, and protecting the lives and property of drivers and other road users. Simultaneously, the optical camera, equipped with a protective lens, reduces the probability of camera damage, extends its lifespan, and reduces equipment maintenance costs. The guide channel and rounded corner design reduce wind resistance of the sliding block and minimize airflow impact, not only extending the sliding block's lifespan but also improving vehicle stability during driving. The cross groove at the inner end of the sliding block reduces its overall weight and energy consumption during pushing, optimizing the device's energy efficiency. Furthermore, the extension plate design increases the sliding block's extension length, expanding the optical camera's shooting angle and further improving the observation effect.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] The embodiments of this utility model will be described below based on its overall structure.
[0033] Example 1
[0034] An optical component installed in a car rearview mirror, such as Figure 1 - Figure 5 As shown, the rearview mirror 1 is included, and a sliding block 2 is slidably installed inside the rearview mirror 1. The outer wall of the rearview mirror 1 is provided with a mounting groove 21 corresponding to the sliding block 2, which ensures that the sliding block 2 can slide smoothly on the rearview mirror 1. At the same time, when the sliding block 2 slides out of the rearview mirror 1, the mounting groove 21 will also support the sliding block 2. The shape of the outer end face of the sliding block 2 is the same as the shape of the outer wall of the rearview mirror 1, so that after the sliding block 2 slides into the rearview mirror 1, the outer end face of the sliding block 2 will be integrated with the outer wall of the rearview mirror 1, thereby reducing the impact of the setting of the sliding block 2 on the rearview mirror 1.
[0035] Specifically, an optical camera 3 for taking pictures is provided on the outer wall of the sliding block 2. At the same time, the picture captured by the optical camera 3 is transmitted to the car's center console (the specific principle is well-known technology and will not be described in detail here). The outer wall of the sliding block 2 is also equipped with a protective lens 30 for protecting the optical camera 3. By setting the protective lens 30, the optical camera 3 is prevented from directly contacting the outside air, thereby reducing the probability of damage to the optical camera 3.
[0036] In this embodiment, a guide groove 31 is provided on the outer wall of the sliding block 2, and the protective lens 30 is located entirely within the guide groove 31. This ensures that the setting of the protective lens 30 will not affect the sliding of the sliding block 2 during actual use. Since the end faces of the upper and lower ends of the guide groove 31 and the end face of the protective lens 30 are all arc-shaped, when the sliding block 2 slides out of the rearview mirror 1 and there is wind blowing towards the sliding block 2, the protective lens 30 and the guide groove 31 will guide the airflow, reduce the impact of the airflow on the sliding block 2, further extend the service life of the sliding block 2, and effectively reduce the wind resistance of the sliding block 2.
[0037] Please see Figure 3 - Figure 5 The outer corners of the sliding block 2 are all designed with rounded corners. The rounded corners can further reduce the impact of airflow on the sliding block 2. At the same time, the size of the rounded corners can be determined according to the actual use requirements. Furthermore, a sealing gasket is provided on the outer wall of the end of the sliding block 2, which is in contact with the inner wall of the mounting groove 21. When the sliding block 2 slides to the non-operating state, the sealing gasket will be in contact with the inner wall of the mounting groove 21 to increase the sealing between the sliding block 2 and the mounting groove 21, thereby reducing the impact of the mounting groove 21 on the airtightness of the rearview mirror 1 housing.
[0038] Please see Figure 2 - Figure 4The rearview mirror 1 is equipped with a drive mechanism connected to the sliding block 2;
[0039] The drive mechanism can be an electric push rod 22 connected to the sliding block 2, or other electrically controllable telescopic elements. A mounting bracket 23 connected to the electric push rod 22 is installed inside the rearview mirror 1. When the drive mechanism is running, it will push the sliding block 2 out of the rearview mirror 1, causing the optical camera 3 to move out of the rearview mirror 1, so that it can take pictures and collect information about the external situation. At the same time, the operation of the drive mechanism is controlled by the internal system of the car (the specific principle is well known technology and will not be described in detail here).
[0040] Please see Figure 3 and Figure 4 The inner end of the sliding block 2 is provided with a cross groove 20 to reduce the overall weight of the sliding block 2 and reduce the energy consumption when pushing the sliding block 2. The outer wall of the cross groove 20 is fixedly connected to the end of the electric push rod 22, so that part of the electric push rod 22 is located in the cross groove 20, which can reduce the space occupied by the electric push rod 22 in the rearview mirror 1 and ensure that the sliding length of the sliding block 2 can be maximized within the limited space inside the rearview mirror 1.
[0041] Example 2
[0042] An optical component installed in a car rearview mirror, such as Figure 1 - Figure 7 As shown, the difference between the technical solution of this embodiment and the first embodiment is that, while retaining the first embodiment, an extension plate 4 is detachably installed on the outer wall of the sliding block 2. The length of the extension plate 4 is determined according to the actual situation. At the same time, the extension plate 4 is provided with a notch to avoid the mounting bracket 23, and a corresponding groove is also opened on the mounting bracket 23 to ensure that the extension plate 4 can slide smoothly inside the rearview mirror 1.
[0043] It should also be noted that the outer surface of the extension plate 4 corresponds to the outer surface of the sliding block 2. During the outward sliding process of the sliding block 2, when the sliding block 2 has completely slid out of the mounting groove 21, the extension plate 4 will begin to slide in the mounting groove 21 to support the sliding block 2 at this time and increase the extension length of the sliding block 2.
[0044] The working principle of this utility model is as follows: When the driver judges that a large truck in front may obstruct the view and affect the observation of traffic lights during the driving process, the vehicle's internal system is activated through the vehicle control signal; after receiving the instruction, the system sends an operation signal to the drive mechanism (taking electric push rod 22 as an example) installed in the rearview mirror 1; after receiving the signal, the electric push rod 22 is activated, and because its end is fixedly connected to the cross groove 20 at the inner end of the sliding block 2, when the electric push rod 22 extends, it pushes the sliding block 2 to slide in the mounting groove 21 of the rearview mirror 1;
[0045] Because the shape of the outer end face of the sliding block 2 is the same as the shape of the outer wall of the rearview mirror 1, the mounting groove 21 supports the sliding block 2 during the sliding process; when the sliding block 2 slides out of the rearview mirror 1, the optical camera 3 installed on the outer wall of the sliding block 2 is exposed; the optical camera 3 captures the traffic light image and transmits the image information to the car's center console through the known transmission principle for the driver to observe and assist in judging the status of the traffic lights;
[0046] Because the protective lens 30 on the outer wall of the sliding block 2 can protect the optical camera 3 and prevent the optical camera 3 from directly contacting the outside air, reducing the risk of damage; at the same time, because the outer wall of the sliding block 2 is provided with a guide groove 31, and the end faces of its upper and lower ends and the end face of the protective lens 30 are all arc-shaped, when the sliding block 2 slides out of the rearview mirror 1, when there is wind blowing towards the sliding block 2, the guide groove 31 and the protective lens 30 can guide the airflow, reduce the impact of the airflow on the sliding block 2, reduce wind resistance, and thus extend the service life of the sliding block 2;
[0047] After the sliding block 2 is completely slid out of the mounting groove 21, the extension plate 4 installed on the outer wall of the sliding block 2 begins to slide in the mounting groove 21. The extension plate 4 is provided with a notch to avoid the mounting bracket 23, and the mounting bracket 23 also has a corresponding sliding groove to ensure that the extension plate 4 slides smoothly. The extension plate 4 supports the sliding block 2 and increases the extension length of the sliding block 2, so that the optical camera 3 can obtain a better shooting angle.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
