Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, and in particular to a vehicle-mounted camera assembly. Meanwhile, the utility model also relates to a vehicle provided with the vehicle-mounted camera assembly. Background Art

[0002] At present, most of the smart driving cameras on passenger cars are installed on plastic brackets by snap-fitting, and the plastic brackets are bonded to the front windshield with PU adhesive, forming only one seal. In addition, since the camera and the plastic bracket are snap-fitted, the plane where the camera is located is only zero contact with the plastic bracket, so there will be a small gap.

[0003] In winter, when the temperature is below zero, especially when it reaches minus 15 degrees, after the car has been driving for a while, the temperature difference between the inside and outside of the car is large. At this time, the humidity inside the car is high due to the water vapor brought out by the breathing of the people in the car. The water vapor will enter the cavity in front of the smart driving camera through the narrow gap between the smart driving camera and the plastic bracket. The water vapor in the cavity will liquefy on the glass surface when it encounters the cold glass surface. The water vapor in the cavity will become less after liquefaction. The water vapor in the cab continues to flow into the cavity due to the potential energy. Over time, small water droplets of pre-condensation will continue to appear on the glass surface, forming water mist.

[0004] However, due to the small cavity gap between the plastic bracket and the front windshield, and the high position, the air conditioner cannot be used to blow the mist away, and it can only be dried by sunlight or a handheld hair dryer, causing the mist to condense on the glass for a long time. The long-term condensed mist will block the smart driving camera, thereby limiting the function of the smart driving camera, and making it impossible to use related functions such as smart driving or cruise. If this happens in a vehicle that is using smart driving, it may cause irreversible risks inside or outside the vehicle.

[0005] In addition, when water vapor enters the cavity, it will also absorb a certain amount of dust, which will cause the glass surface to become dirty over time. It is difficult to remove the dirt on the glass surface, which will limit the function of the smart driving camera and even make it impossible to use functions such as smart driving or cruising.

[0006] For this reason, existing vehicles have poor sealing effects on the cavity in front of the camera, which is easily invaded by water mist and dust and affects the use of the camera, limiting the vehicle's forward vision function and making it impossible to implement functions such as smart driving or cruising. In severe cases, it may even cause irreversible safety risks inside or outside the vehicle. Utility Model Content

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] Embodiment 1

[0046] The present embodiment relates to a vehicle-mounted camera assembly, which can prevent water mist and dust from invading the cavity 10, so that the front position of the camera 132 will not be fogged all day long, ensuring that the use effect of the camera 132 is not affected, thereby improving the stability of the vehicle's forward vision function.

[0047] In terms of overall structure, Figures 1 to 10 As shown, the vehicle-mounted camera assembly of this embodiment includes a mounting bracket arranged on the front windshield 11, a cavity 10 arranged between the mounting bracket and the front windshield 11, and a camera component 13 arranged on the mounting bracket.

[0048] In addition, a first sealing portion 14 is provided between the mounting bracket and the front windshield 11 to seal the cavity 10. A mounting hole 121 is provided on the mounting bracket to accommodate the camera 132 of the camera assembly 13. The mounting hole 121 is communicated with the cavity 10 to form a path for external light to enter the camera 132 together with the cavity 10, and a second sealing portion 15 is provided between the camera 132 and the mounting hole 121.

[0049] It is worth mentioning that the related structural parts not mentioned in the vehicle-mounted camera assembly of this embodiment can all refer to the camera assembly installed on the front windshield 11 known to those skilled in the art. For example, the mounting bracket is usually located in the middle of the left and right direction of the front windshield 11 and close to the top of the front windshield 11, thereby ensuring that the camera 132 has a larger field of view, thereby achieving a better shooting effect. At the same time, in order to improve practicality, the mounting bracket can also be provided with a mounting portion for installing related components such as an interior rearview mirror.

[0050] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, see Fig. 9 As shown, the first sealing portion 14 is a sealing gasket or a sealing rubber layer disposed between the mounting bracket and the front windshield 11 .

[0051] And, if Fig.10 As shown, and also as a preferred implementation form, the second sealing portion 15 of this embodiment adopts a sealing ring disposed between the camera 132 and the mounting hole 121. It can be understood that the first sealing portion 14 adopts a sealing gasket or a sealing rubber layer, and the second sealing portion 15 adopts a sealing ring, which not only has a simple structure and is conducive to sealing operation, but also facilitates cost reduction design.

[0052] In a specific implementation, the first sealing portion 14 of this embodiment is arranged to extend along the circumference of the cavity 10 to effectively seal the gap between the mounting bracket and the front windshield 11 formed outside the cavity 10 .

[0053] The structural shape of the cavity 10 can be set and adjusted according to the shooting requirements of the camera 132, for example, Figure 4 and Figure 5 As shown, along the front-rear direction of the vehicle, the two side walls of the cavity 10 extend forward and are inclined outward in the left-right direction of the vehicle (that is, inclined outward). At the same time, the bottom wall of the cavity 10 is preferably arranged to extend forward and tilt downward so that the camera 132 has a larger shooting angle to meet its shooting needs.

[0054] Furthermore, when the first sealing portion 14 is a sealing adhesive layer, it can be directly coated on the mounting bracket, and when the mounting bracket is mounted on the front windshield 11 , the first sealing portion 14 forms a seal for the cavity 10 .

[0055] At the same time, when the first sealing portion 14 adopts a sealing gasket, it is also preferably bonded to the mounting bracket and the front windshield 11. For example, glue can be first provided on both sides of the sealing gasket, and one side of the sealing gasket is bonded to the mounting bracket. When the mounting bracket and the front windshield 11 are installed, the other side of the sealing gasket is bonded and fixed to the front windshield 11, thereby realizing the arrangement of the first sealing portion 14 and the sealing of the cavity 10.

[0056] Secondly, the first sealing part 14 and the second sealing part 15 preferably have a certain amount of compression during installation, and the compression amount is not less than 0.5 mm, such as 0.5 mm, 0.7 mm or 0.9 mm, etc., to ensure a good sealing effect between the mounting bracket and the front windshield 11 and between the camera 132 and the mounting hole 121.

[0057] Furthermore, the sealing pad and the sealing ring of the present embodiment can be made of materials such as EPDM rubber, nitrile rubber, silicone, polyurethane, etc., so as to have a good sealing effect. The sealing adhesive layer can be made of polyurethane adhesive to have good bonding strength and good high temperature resistance, low temperature resistance, hydrolysis resistance and aging resistance.

[0058] Secondly, in this embodiment, as a preferred implementation form, see Figure 4 , Figure 6 and Figure 7 As shown, the camera 132 is provided with a groove 1321, and the second sealing portion 15 is embedded in the groove 1321. Such a configuration is conducive to improving the installation stability and sealing reliability of the second sealing portion 15.

[0059] In detail, the specific structure and shape of the groove 1321 of this embodiment can be set and adjusted according to the size and shape of the second sealing portion 15. For example, the cross-sectional profile or depth dimension of the groove 1321 is compatible with the second sealing portion 15, and it is ensured that when the camera 132 is installed in the mounting hole 121, the second sealing portion 15 has a compression amount of not less than 0.5 mm.

[0060] At the same time, in addition to setting the groove 1321 on the camera 132, this embodiment can also set an inner groove on the inner wall of the mounting hole 121 to fix and install the second sealing part 15, which can also achieve good sealing and installation effects.

[0061] In addition, in this embodiment, as a preferred implementation form, see Figure 3 and Figure 4 As shown, the mounting bracket includes a mounting plate 12. The mounting plate 12 is provided with a bulging portion 122 bulging on a side facing away from the front windshield 11, and a cavity 10 is formed between the bulging portion 122 and the front windshield 11 on the side facing the front windshield 11.

[0062] The shape of the bulge 122 can be as follows: Figure 4 As shown, it is visually L-shaped as a whole, and the bottom of the bulge 122 extends forward along the front-rear direction of the vehicle and tilts downward, so as to facilitate the formation of the above-mentioned cavity 10 between the mounting plate 12 and the front windshield 11 for the camera 132 to shoot.

[0063] The bulge 122 of this embodiment can preferably be integrally formed with the mounting plate 12 , for example, by integral injection molding. This is not only beneficial for ensuring the molding quality of the mounting bracket, but also beneficial for the mounting plate 12 to cooperate with the front windshield 11 to form the cavity 10 .

[0064] Furthermore, see Figure 4 As shown, as a preferred implementation form, a receiving platform 123 is provided on the bulging portion 122 of this embodiment, the shell 131 of the camera assembly 13 abuts against the receiving platform 123, and a third sealing portion 16 is provided between the shell 131 and the receiving platform 123.

[0065] The benefit of setting up the mounting platform 123 is that it is convenient for positioning and installing the camera assembly 13, and the setting of the third sealing portion 16 can enhance the sealing effect between the camera assembly 13 and the mounting bracket, thereby further ensuring the sealing of the cavity 10 on the basis of two seals.

[0066] Specifically, in order to improve the installation stability of the camera assembly 13, the mounting platform 123 is preferably provided with a certain thickness to increase the axial length of the mounting hole 121, thereby facilitating the installation requirements of the camera 132. At the same time, the contour size of the abutment surface between the mounting platform 123 and the shell 131 is set as large as possible without affecting the installation of the camera assembly 13, so as to facilitate clamping the third sealing part 16 between the shell 131 and the mounting platform 123 and ensure the sealing effect.

[0067] At the same time, in this embodiment, as a preferred implementation form, see Fig.10 As shown, the third sealing portion 16 is annular and arranged along the circumference of the camera 132 to facilitate ensuring a good sealing effect between the camera assembly 13 and the mounting bracket.

[0068] That is, in the specific structure, the third sealing portion 16 can adopt the same sealing gasket as the first sealing portion 14 , and can be sandwiched between the shell 131 and the receiving platform 123 to form an effective seal between the shell 131 and the receiving platform 123 .

[0069] Moreover, the third sealing portion 16 preferably has the same compression amount as the first sealing portion 14 or the second sealing portion 15 , such as 0.5 mm, 0.7 mm or 0.9 mm, etc., which is not less than 0.5 mm, to ensure the sealing effect between the shell 131 and the supporting platform 123 .

[0070] In addition, in this embodiment, as a preferred implementation form, the shell 131 and the mounting plate 12 are detachably connected to facilitate the convenience of disassembly and assembly between the camera assembly 13 and the mounting bracket.

[0071] In the specific implementation, in this embodiment, as a preferred implementation form, see Figure 2 and Figure 8 As shown, a first hook 1311 is provided on the housing 131 and a second hook 124 is provided on the mounting plate 12 , and the first hook 1311 and the second hook 124 are hooked together.

[0072] By cooperating with the first snap hook 1311 and the second snap hook 124 , the snap connection between the camera assembly 13 and the mounting bracket can be achieved, which makes the structure simpler and the operation easier while realizing a detachable connection between the two.

[0073] It should be noted that the number and arrangement of the first snap-in hooks 1311 and the second snap-in hooks 124 can be set and adjusted according to the actual snap-in requirements between the shell 131 and the mounting plate 12. For example, a first snap-in hook 1311 is set at the top of the shell 131, two first snap-in hooks 1311 are set at the bottom of the shell 131, and the corresponding number and position of the second snap-in hooks 124 are set on the mounting plate 12.

[0074] Of course, in addition to the above-mentioned snap-on connection, other detachable connection methods may be used between the housing 131 and the mounting plate 12 of this embodiment, such as screw connection or snap-on plus screw connection. When screw connection is used, a blind hole for screw connection may be arranged on the housing 131, and a mounting through hole corresponding to the blind hole may be arranged on the mounting plate 12. Subsequently, the bolts may be passed through the mounting through hole and screwed into the corresponding blind hole to realize the screw connection between the housing 131 and the mounting plate 12.

[0075] In addition, when assembling the vehicle-mounted camera assembly of this embodiment, first, the camera component 13 can be dried by hot air before installing it. Secondly, the second sealing portion 15 is embedded in the groove 1321 of the camera 132. Finally, the shell 131 and the mounting plate are hooked together through the first hook 1311 and the second hook 124 (that is, the camera component 13 and the mounting bracket are hooked). At the same time, the second sealing portion 15 is squeezed between the shell 131 of the camera component 13 and the inner wall of the mounting hole 12 to divide the space at both ends of the camera 132, thereby preventing water vapor and dust from entering the cavity 10 from one side of the shell 131 through the mounting hole 121.

[0076] Among them, before the camera assembly 13 is clamped with the mounting bracket (that is, before the camera 12 is installed in the mounting hole 121), a third sealing portion 16 is arranged at the connection between the camera 132 and the shell 131, and a first sealing portion 14 is also arranged on the mounting bracket's contact surface with the front windshield 11 (along the circumference of the cavity). In this way, when the camera assembly 13 is clamped with the mounting bracket, the first sealing portion 14 realizes the sealing between the mounting bracket and the front windshield 11, blocking the possibility of water vapor and dust entering the cavity 10 from the gap between the two, and the third sealing portion 16 realizes the sealing between the shell 131 and the supporting platform 123, and cooperates with the second sealing portion 15 to effectively block the possibility of water vapor and dust entering the cavity 10 from one side of the shell 131 through the mounting hole 121, so that this position ensures that the use effect of the camera 132 is not affected. The vehicle-mounted camera assembly of this embodiment can form two seals to completely seal the cavity 10 through the cooperation of the first sealing part 14 and the second sealing part 15, thereby preventing water mist and dust from invading the cavity 10, ensuring that the use effect of the camera 132 is not affected, thereby helping to improve the stability of the vehicle's forward vision function and ensure the safety of intelligent driving or cruise functions. At the same time, the camera 132 is less likely to be infected by water mist and dust, which is also conducive to improving the durability of the camera 132.
