Description

Technical Field

[0001] The utility model relates to the technical field of automobile safety assistance, in particular to an automobile indirect vision device. Background Art

[0002] According to the mandatory national standard GB 15084-2022 "Performance and Installation Requirements for Indirect Vision Devices for Motor Vehicles", M1 vehicles must be installed with Class I and Class III vision devices. Class III vision devices will form a 4-meter-long blind spot from the driver's eye point in the longitudinal symmetric plane of the vehicle. Figure 5 As shown, smaller motor vehicles and pedestrians cannot be detected in time, resulting in traffic accidents when the vehicle changes lanes and turns. Summary of the invention

[0003] The utility model is intended to provide an indirect vision device for automobiles to solve the problem that a Class III vision device will form a blind spot of 4 meters in length from the driver's eye point in the longitudinal symmetric plane of the vehicle, resulting in failure to timely detect smaller motor vehicles and pedestrians, and causing traffic accidents during vehicle lane changes and turns.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An indirect field of vision device for an automobile comprises an optical signal receiving device, a connecting tube, a photosensitive element, an electronic display screen, a power supply device, and a rearview mirror housing, wherein the optical signal receiving device comprises a lens, and the lens is arranged at one end of the connecting tube, and the connecting tube is in the shape of a letter "B", and two reflecting mirrors with opposite mirror surfaces are installed at two corners in the connecting tube, and the other end of the connecting tube is connected to the photosensitive element, and the photosensitive element and the electronic display screen are connected to the power supply device, and the rearview mirror housing comprises a shell and a lens, and the optical signal receiving device, the connecting tube, the photosensitive element, and the power supply device are sequentially installed in the rearview mirror housing, and a light-transmitting hole is opened at a position corresponding to the installation position of the lens.

[0006] The principle of this scheme is: this device is a car rearview mirror assembly, and the light passes through the light-transmitting hole on the lens corresponding to the lens installation position, is collected by the optical signal receiving device, and is transmitted to the connecting tube. Through the periscope principle, the collected light is reflected to the photosensitive element through the reflecting mirror surface set in the connecting tube. The photosensitive element converts the received optical image into a digital signal, and converts the digital signal into a display screen image, which is displayed on the electronic display screen for the driver's reference.

[0007] The advantages of this solution are:

[0008] 1. This device can solve the problem of blind spots within 4 meters behind the driver's eyes when the car is driving, which is prone to traffic accidents when changing lanes or turning. The use of lenses and electronic display screens can make the scene capture and display in the blind spot more accurate and clear, and improve the driver's judgment accuracy of the environment in the blind spot.

[0009] 2. This device is an independent system, which is not affected by the reliability of the vehicle system and is not limited by the vehicle's appearance. It can be adapted to most models of cars.

[0010] 3. The device has a simple structure, is easy to install, and is highly interchangeable. Users can change the vehicle at will without complicated disassembly and assembly steps.

[0011] Preferably, as an improvement, the two reflectors are installed at an angle of 45 degrees. This installation angle can keep the reflected image in true proportion without causing deformation such as compression and stretching, which is helpful for the driver to grasp the real scene in the blind spot.

[0012] Preferably, as an improvement, the photosensitive element is a CCD photosensitive element. The CCD photosensitive element has the advantage of presenting high-definition images even in low-light environments, which helps the driver to grasp the scenes in the blind spot when driving at night or in other dark environments.

[0013] Preferably, as an improvement, the electronic display screen is arranged on the housing, and a vertical shaft is arranged on the side of the housing close to the vehicle body, and the electronic display screen is connected to the housing through the vertical shaft and can rotate vertically relative to the housing. The electronic display screen can be unfolded when in use and closed into the rearview mirror housing when not in use, so as to protect the electronic display screen.

[0014] Preferably, as an improvement, a connection base is fixedly provided on the lower side of the connection tube, and the bottom of the connection base is bonded to the housing. The connection base is used to support the connection tube and the lens, and a strong glue is bonded to the bottom to fix the connection tube and the lens in the installation position, so as to avoid the connection tube and the lens being misaligned due to the bumps of the car, resulting in the inability to collect light or the light path being tilted, which affects the imaging.

[0015] Preferably, as an improvement, the power supply device includes a lead-acid battery. A rechargeable lead-acid battery or a No. 1 battery can be selected as the power source. The former is reusable, energy-saving and environmentally friendly, and the latter is highly replaceable, more convenient and safer.

[0016] Preferably, as an improvement, the rearview mirror housing is a solar housing. The solar rearview mirror housing can charge a rechargeable lead-acid battery to ensure a good endurance of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is further described in detail through specific implementation methods:

[0023] The reference numerals in the drawings of the specification include: lens 1, connecting tube 2, connecting base 2-1, first reflector 3-1, second reflector 3-2, CCD photosensitive element 4, lead-acid battery 5, wire 6, electronic display screen 7, housing 8, lens 9.

[0024] Embodiment 1 is basically as attached Figure 1 , 2 , 3, 4 as shown:

[0025] An indirect vision device for a car comprises an optical signal receiving device, a connecting pipe 2, a photosensitive element, an electronic display screen 7, a power supply device, and a rearview mirror housing, as shown in the attached Figure 1 As shown, the optical signal receiving device includes a lens 1, which is arranged at one end of a connecting tube 2, and the other end of the connecting tube 2 is connected to a photosensitive element. The photosensitive element and the electronic display screen 7 are connected to the power supply device through a wire 6, and the photosensitive element is a CCD photosensitive element 44. A connecting base 2-1 is fixedly arranged on the lower side of the connecting tube 2, and a strong glue is adhered to the bottom of the connecting base 2-1, which is used to fix the connecting tube 2 and the lens 1 and the CCD photosensitive element 4 connected thereto on the housing 8. The power supply device includes a lead-acid battery 5, which is used to power the CCD photosensitive element and the electronic display screen. The lead-acid battery 5 can be selected as a rechargeable type or a dry battery, such as two No. 1 batteries.

[0026] As attached Figure 1 , 3As shown, the rearview mirror housing includes a housing 8, a lens 9, an optical signal receiving device, a connecting tube 2, a photosensitive element, and a power supply device are sequentially installed in the rearview mirror housing. A light-transmitting hole of the same size as the lens 1 is opened at a position corresponding to the installation position of the lens 9 and the lens 1. The light-transmitting hole is used for light to pass through the lens 9 so that it can be captured by the lens 1. The electronic display screen 7 is arranged on the left side of the housing 8, and a vertical shaft is arranged on the left side of the housing 8. The electronic display screen 7 is connected to the housing 8 through the vertical shaft and can rotate vertically relative to the housing 8. As shown in the attached figure Figure 2 As shown, when not in use, the electronic display screen 7 can be rotated back to the rearview mirror housing, which has a certain waterproof and scratch-proof effect on the electronic display screen 7.

[0027] As attached Figure 4 As shown, the connecting tube 2 is in the shape of a letter "Y". Two reflectors 3-1 and 3-2 with opposite mirror surfaces are installed at the two corners of the connecting tube 2. The light enters from the end where the lens is set. When it contacts the first reflector 3-1, the light path rotates counterclockwise and deviates from the original light path. When it contacts the second reflector 3-2, the light path rotates clockwise and passes out from the other end of the connecting tube 2. The two reflectors 3-1 and 3-2 are installed at an angle of 45 degrees. At this angle, when the light contacts the first reflector 3-1, its deviation angle is exactly 90 degrees relative to the original light path, and the reflected image can present the same proportion as the real scene. When the light contacts the second reflector 3-2, the principle is the same as above.

[0028] In actual application, before starting the car, the electronic display screen 7 is rotated out from the left side of the housing 8 and adjusted to a position where the driver can fully observe it before starting the car. The lens 1 transmits the scene image collected in the blind spot of the field of view to the connecting tube 2. The two mirrors 3-1 and 3-2 installed at 45 degrees in the connecting tube reflect the image to the CCD photosensitive element 4 in real proportion. The photosensitive element 4 converts the optical image into a digital signal, and converts the digital signal into a display screen image, which is displayed to the driver through the electronic display screen 7 for the driver's reference. When the device is not needed, the electronic display screen 7 can be rotated back to the rearview mirror housing to protect the electronic display screen 7 from being scratched.

[0029] Embodiment 2:

[0030] The difference between Example 2 and Example 1 is that the rearview mirror housing of Example 2 is a solar housing. Through the solar rearview mirror housing, when the car is driving on a sunny day, the rechargeable lead-acid battery can be replenished with electricity at any time without stopping the indirect vision device of the car for charging, thereby ensuring a good endurance of the entire device.

[0031] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
