[0002] Car cameras are widely used in the automotive field, and their application scenarios are becoming increasingly diverse, from the earliest driving records and reversing images to intelligent recognition, ADAS assisted driving, etc. Therefore, car cameras are also known as the "eyes of autonomous driving" and have become the core equipment in the field of autonomous driving.

[0003] With the rapid development of the automotive industry, the quality requirements for automotive cameras are getting higher and higher. In addition, the competition in the automotive industry is fierce, so there is a great challenge to reduce the cost and ensure the quality of cameras. Therefore, most automotive cameras in the low-end market will adopt a plastic shell design. At present, automotive cameras mainly use AA technology to mount lenses. Since the camera shell and lens holder are both made of plastic materials, and the surface of the plastic lens holder is relatively smooth, it is easy to have a problem of poor pulling force after the lens is mounted, resulting in the quality risk of the existing automotive cameras falling off the lens holder, thereby affecting the functional safety of the car.

[0004] Therefore, in view of the technical problems existing in existing vehicle-mounted cameras such as those mentioned above, we have specifically designed a plastic shell vehicle-mounted camera that improves the pulling force of the lens. Utility Model Content

[0027] See also Figure 2-4In this embodiment, the top of the fixing rod 9 is fixed to the bottom of the flange 8, the limiting block 10 is integrally formed at the bottom of the fixing rod 9, and the fixing rod 9 and the limiting block 10 form an L-shaped structure.

[0028] Specifically, the fixing rod 9 is fixed to the flange 8, and the rotation of the flange 8 can be used to drive the fixing rod 9 to rotate, thereby forming an L-shaped fixing rod 9 and a limiting block 10, thereby forming a tensile structure, which can improve the connection firmness between the lens body 7 and the lens mount 2.

[0029] See also Figure 1-3 In this embodiment, the width of the limit block 10 is adapted to the width of the limit groove 4, the width of the fixing rod 9 is adapted to the width of the sliding opening 5, and the limit block 10 enters the deep part of the limit groove 4 through the screwing of the flange 8 and is placed at the bottom of the limit baffle 6.

[0030] Specifically, the opening of the limiting groove 4 can facilitate the entry of the limiting block 10 on the one hand, and can cooperate with the limiting baffle 6 to engage the limiting block 10 in the limiting groove 4 on the other hand, thereby playing a limiting role. The design of the sliding mouth 5 facilitates the entry of the fixing rod 9.

[0031] See also Figure 1-2 In this embodiment, the plurality of limiting grooves 4 in the two annular grooves 3 are arranged in pairs, and the plurality of tensile components at the bottom of the flange 8 are also arranged in pairs.

[0032] Specifically, one limiting groove 4 corresponds to one tensile component, so that each tensile component can enter into one limiting groove 4 during installation, thereby increasing the tensile area and improving the overall tensile resistance of the lens body 7.

[0033] See also Figure 3 and Figure 5 In this embodiment, an adhesive area 801 is provided in an annular shape at the bottom of the flange 8 and near the tops of the two annular grooves 3 , and pits 802 are evenly formed on the surface of the adhesive area 801 .

[0034] Specifically, by designing the adhesive area 801 and designing the pit 802 on the adhesive area 801, the contact area with the AA glue can be increased, and the pit 802 area can be better bonded with the AA glue.

[0035] See also Figure 4 In this embodiment, a silicone gasket is fixed to the bottom of each limiting card block 10 , and the area of ​​the silicone gasket is the same as the area of ​​the bottom of the limiting card block 10 .

[0036] Specifically, by designing a silicone gasket at the bottom of the limit block 10, a certain pressing force needs to be applied when the limit block 10 enters the limit groove 4, thereby causing the silicone gasket to deform (become thinner). When the limit block 10 is placed at the bottom of the limit baffle 6, the filling effect of the silicone gasket can be utilized to make the limit block 10 more stable in the limit groove 4.

[0037] See also Figure 2-3 In this embodiment, the top of the lens mount 2 is designed as a flat structure, and the bottom of the flange 8 is also designed as a flat structure.

[0038] Specifically, through the above design, the lens mount 2 and the flange 8 can be more closely fitted, thereby improving the stability of the two after being glued together by AA glue.

[0039] During installation: first apply AA glue in the annular groove 3 so that the AA glue fills the two annular grooves 3, then take the lens body 7, place the flange 8 above the lens mount 2, and then make the multiple limit blocks 10 enter the multiple limit grooves 4 respectively. At this time, the lens body 7 can be rotated, thereby driving the flange 8 to rotate, driving the limit blocks 10 to rotate and be placed at the bottom of the limit baffle 6, and driving the fixing rod 9 to enter the sliding mouth 5. When the lens body 7 is limited by the fixing rod 9 and the end point of the sliding mouth 5 and cannot rotate, the purpose of loading the lens body 7 onto the lens mount 2 is completed. At this time, the bottom of the flange 8 is tightly fitted on the top of the lens mount 2, so that the adhesive area 801 at the bottom of the flange 8 adheres to the AA glue in the annular groove 3, thereby completing the gluing.
