Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive camera mounting structure. Background Technology

[0002] As a crucial component of automotive active safety assistance systems, reversing cameras effectively address the pain points of "large blind spots and difficulty in judging distances" when reversing by capturing the rear view in real time and transmitting it to the in-car display screen. They have gradually evolved from being a feature in high-end models to becoming standard equipment in family cars. Their core value lies in "reducing collision risk and improving the convenience of reversing."

[0003] The rear of the trunk typically has a double-layer structure consisting of a metal cover (outer layer) and a plastic interior panel (inner layer). Some models have a pre-installed camera mounting port at this location, which usually requires an opening at the rear of the trunk and screws for locking. When the screws are locked, the thread gap between the screw and the base of the vehicle body, as well as the contact surface between the screw head and the connecting part, are all potential channels for water ingress. After drilling, the stress on the metal cover will concentrate at the edge of the hole (mechanically known as the "hole effect"). If the hole diameter is large, it will reduce the cover's resistance to deformation in the area around the hole. Slight vibrations of the trunk cover during vehicle operation (or the impact force when closing the trunk) can cause "micro-cracks" to form at the edge of the hole over time, which may lead to local dents or cracks in the cover in severe cases. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an automotive camera mounting structure that solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a car camera mounting structure, comprising a car trunk cover, a base plate, and a camera integrally formed and fixedly connected to the base plate. A base block is fixedly connected to the other side of the base plate. An mounting opening is provided on the car trunk cover. The base block passes through the mounting opening. A connecting strip is detachably installed on the end of the base block away from the camera. A pressure strip is fixedly connected to the side of the connecting strip near the base plate. The pressure strip and the base plate are distributed on both sides of the car trunk cover.

[0008] Preferably, the base block is provided with four rectangularly distributed internally threaded sleeves on the side away from the substrate, and the connecting strip is provided with four rectangularly distributed positioning holes. The internally threaded sleeves are disposed through the positioning holes, and the connecting strip is connected to the internally threaded sleeves by bolts. The threaded end of the bolts is disposed through the positioning holes and threaded into the internally threaded sleeves.

[0009] Preferably, the pressure strip has multiple linearly distributed grooves on the side near the substrate, and each groove is provided with an elastic pressing mechanism.

[0010] Preferably, the elastic clamping mechanism includes a spring fixed to the inner wall of the tank and a stop block fixed to the other end of the spring. A pressure ball is fixedly connected to the other end of the stop block, and one end of the pressure ball extends to the outside of the tank.

[0011] Preferably, the inner diameter of the groove opening is smaller than the diameter of the pressure ball.

[0012] Preferably, an annular sealing ring is fixedly provided on the inner wall of the mounting opening of the car trunk cover.

[0013] (III) Beneficial Effects

[0014] This utility model provides a car camera mounting structure, which has the following advantages:

[0015] 1. In this utility model, the pre-set mounting opening on the trunk lid of the car serves as the passage for the base block, ensuring that the base block does not wobble when passing through, and eliminating the need to enlarge or drill new holes in the trunk lid of the car. After the base block passes through the mounting opening, a connecting strip is installed on the inner side of the trunk lid of the car (the side of the plastic interior panel), and locked to the inner threaded sleeve at the end of the base block by bolts. At this time, the outer base plate and the inner pressure strip form a "two-way clamping force" on the trunk lid of the car, firmly fixing the entire camera to the trunk lid of the car, without the need to rely on screws after drilling holes in the trunk lid of the car for locking.

[0016] 2. In this utility model, the shape of the trunk cover is mostly "arc". Traditional rigid strips (such as integral plastic strips) cannot deform with the arc surface. However, during installation, this application does not require strict calibration of the matching degree between the strip and the arc of the trunk cover. The strip is only initially fixed with bolts. The pressure ball will automatically adapt to the arc of the trunk cover under the action of the spring, reducing the positioning and adjustment steps during installation and improving assembly efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a car camera mounting structure, including a car trunk cover 10, a base plate 1, and a camera 2 integrally formed and fixedly connected to the base plate 1. A base block 11 is fixedly connected to the other side of the base plate 1. An installation opening 1001 is provided on the car trunk cover 10. The base block 11 is set through the installation opening 1001. A connecting strip 4 is detachably installed on the end of the base block 11 away from the camera 2. A pressure strip 5 is fixedly connected to the side of the connecting strip 4 near the base plate 1. The pressure strip 5 and the base plate 1 are distributed on both sides of the car trunk cover 10.

[0025] The outer base plate 1, the inner connecting strip 4 and the pressure strip 5 form a "two-way clamping force" on the car trunk cover 10, and the inner and outer sides work together to firmly fit the camera 2 with the car trunk cover 10, which is compatible with the curved structure of the car trunk cover 10.

[0026] Reference Figure 4 The base block 11 is provided with four rectangularly distributed internal threaded sleeves 3 on the side away from the substrate 1. The connecting strip 4 is provided with four rectangularly distributed positioning holes 401. The internal threaded sleeves 3 are installed through the positioning holes 401. The connecting strip 4 is connected to the internal threaded sleeves 3 by bolts 6. The threaded end of the bolt 6 is installed through the positioning hole 401 and the thread is inserted into the internal threaded sleeve 3.

[0027] The pre-set mounting opening 1001 on the trunk lid 10 serves as a passage for the base block 11, ensuring that the base block 11 passes through without shaking, and eliminating the need for enlarging or drilling new holes in the trunk lid 10. After the base block 11 passes through the mounting opening 1001, a connecting strip 4 is installed on the inner side of the trunk lid 10 (the side with the plastic interior panel), and locked to the inner threaded sleeve 3 at the end of the base block 11 by bolts 6. At this time, the outer base plate 1 and the inner pressure strip 5 form a "two-way clamping force" on the trunk lid 10, firmly fixing the entire camera 2 to the trunk lid 10 without relying on additional screws after drilling holes in the trunk lid 10. Therefore, the problem of water leakage after drilling in the prior art is solved, and cracking after long-term use is also avoided.

[0028] Reference Figure 3 and Figure 5 The pressure strip 5 has multiple linearly distributed grooves 501 on the side near the substrate 1, and each groove 501 is equipped with an elastic pressing mechanism.

[0029] The modular elastic clamping mechanism enables adaptive clamping of the complex surface of the car trunk cover 10, ensuring the stability of the camera 2 installation while being compatible with the structural differences of the trunk cover 10 of different car models.

[0030] Reference Figure 5 The elastic clamping mechanism includes a spring 7 fixed to the inner wall of the groove 501 and a stop block 8 fixed to the other end of the spring 7. A pressure ball 9 is fixedly connected to the other end of the stop block 8, and one end of the pressure ball 9 extends to the outside of the groove 501.

[0031] The shape of the trunk cover 10 of a car is often an "arc" with a certain curvature. Traditional rigid strips 5 (such as integral plastic strips 5) cannot deform with the arc surface.

[0032] During installation, this application does not require strict calibration of the arc matching between the pressure strip 5 and the trunk cover 10 of the car. The pressure strip 5 is initially fixed by the bolt 6, and the pressure ball 9 will automatically adapt to the arc of the trunk cover 10 of the car under the action of the spring 7, reducing the positioning and adjustment steps during installation and improving assembly efficiency.

[0033] Reference Figure 5 The inner diameter of the groove opening of the trough 501 is smaller than the diameter of the pressure ball 9.

[0034] The aforementioned design causes the diameter of the groove opening of the trough 501 to gradually narrow, which is a key structural constraint for the long-term stable operation of the pressure ball 9, and completely avoids the risk of the pressure ball 9 detaching from the trough 501 from a physical perspective.

[0035] Reference Figure 5 An annular sealing ring is fixedly installed on the inner wall of the mounting opening 1001 of the car trunk cover 10.

[0036] The mounting port 1001 serves as a passageway for the base block 11. Although it is precisely matched to the size of the base block 11, the fitting gap is prone to slight changes due to the vibration of the vehicle and temperature changes (such as expansion at high temperatures in summer and contraction at low temperatures in winter), which can become a potential channel for rainwater and sand to enter.

[0037] An annular sealing ring (usually made of EPDM rubber, which is resistant to high and low temperatures and aging) is fixed in the annular groove on the inner wall of the mounting port 1001 (or fixed by adhesive). The original cross-sectional size of the sealing ring is slightly larger than the mating gap between the mounting port 1001 and the base block 11. When the base block 11 passes through the mounting port 1001, the annular sealing ring is compressed by the outer wall of the base block 11, resulting in pre-compression deformation. It then tightly fits the outer wall of the base block 11 and the inner wall of the mounting port 1001, filling the initial mating gap and forming a sealing barrier.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
