Description

Technical Field

[0001] This invention relates to the field of camera technology, specifically to a vehicle-mounted camera mounting structure and camera module. Background Technology

[0002] As the level of intelligent driver assistance gradually increases, the number of camera modules with different functions installed in automobiles is constantly increasing, such as ADAS assistance systems, CMS rearview systems, reversing camera cameras, and driver recording cameras. With the increasing number of cameras per vehicle, the space available for camera installation is becoming increasingly limited. Camera installation and placement are not only restricted by the vehicle's shape but also by other electronic or structural components, making the space increasingly cramped. This leads to increasingly difficult camera installation, poor positioning results, and the need for auxiliary fixtures, further increasing the time, labor, and cost of camera installation.

[0003] Furthermore, cameras located on the exterior of vehicles often face the challenges of cold and humid weather, leading to lens fogging, especially in rainy, snowy, or cold conditions where moisture easily condenses on the lens. This can cause the camera to be unable to consistently and stably output images in complex or extreme environments, affecting driving safety. Therefore, exterior cameras on vehicles often use self-heating camera modules. However, current self-heating camera modules commonly use a connection method that connects the power supply and output signal of the heated lens, including a power connection port for the lens heating element and a signal transmission connection port for the camera. This requires two connector ports, which not only takes up space in the camera module but also complicates the assembly process. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The vehicle-mounted camera mounting structure disclosed in this invention uses a mounting bracket to fix the camera module in place. Simultaneously, a guide groove and a spring arm on the mounting bracket, in conjunction with a vehicle positioning part located in the mounting groove, allow the mounting bracket to slide and fix in place, thereby fixing the camera module in the mounting groove. This mounting method is simple in structure, requires no auxiliary fixtures, and allows for quick and convenient installation.

[0017] This invention discloses a camera module that, through a heating element mounted on the lens, can remove ice, frost, fog, and other deposits adhering to the lens under complex or extreme environmental conditions, ensuring continuous and stable image output and guaranteeing driving safety.

[0041] Example 1

[0042] In order to solve the problems of small camera installation space, difficulty in arranging camera installation structure, difficult installation, poor positioning effect, need for auxiliary jigs, time-consuming and labor-intensive installation, and low efficiency in the prior art, this embodiment discloses a vehicle-mounted camera installation structure.

[0043] Please see Figure 1The figure shows a schematic diagram of a vehicle-mounted camera mounting structure provided in this embodiment.

[0044] Please see Figure 2 The figure shows an exploded view of a vehicle-mounted camera mounting structure provided in this embodiment.

[0045] This embodiment discloses a vehicle-mounted camera mounting structure, such as... Figure 1-2 As shown, it includes: a camera module 1, a mounting bracket 2, and a vehicle body mounting surface 3. The camera module 1 is fixedly connected to the mounting bracket 2. The vehicle body mounting surface 3 is provided with a mounting groove 31 that can accommodate the camera module 1 and the mounting bracket 2. A vehicle body positioning part 34 is provided in the mounting groove 31. The mounting bracket 2 is provided with a guide groove 21 that allows the vehicle body positioning part 34 to slide. A spring arm 22 is provided in the guide groove 21. The mounting bracket 2 is sleeved on the vehicle body positioning part 34 through the guide groove 21. The mounting bracket 2 slides along the guide groove 21 so that the vehicle body positioning part 34 abuts against the spring arm 22, thereby fixing the mounting bracket 2 in the mounting groove 31.

[0046] In other words, in this embodiment, the camera module 1 is directly fixedly connected to the mounting bracket 2, and the mounting bracket 2 is slidably connected to the vehicle body positioning part 34 in the mounting groove 31 through the guide groove 21, thereby realizing the rapid installation of the mounting bracket 2 and the camera module 1.

[0047] In a preferred embodiment, the vehicle positioning part 34 is configured as a vehicle positioning post that matches the guide groove 21.

[0048] Therefore, in this embodiment, the vehicle-mounted camera mounting structure uses a mounting bracket 2 to fix the camera module 1 in place. At the same time, the mounting bracket 2 is slidably fixed by the guide groove 21 and the spring arm 22 on the mounting bracket 2 in conjunction with the vehicle positioning part 34 in the mounting groove 31. This allows the camera module 1 to be fixedly installed in the mounting groove 31. This mounting method has a simple structure and can be quickly installed without the need for auxiliary fixtures, making it convenient to install.

[0049] Please see Figure 3 The figure shows a schematic diagram of the vehicle body mounting surface of a vehicle-mounted camera mounting structure provided in this embodiment;

[0050] Please see Figure 4 The figure shows a schematic diagram of the mounting bracket of a vehicle-mounted camera mounting structure provided in this embodiment.

[0051] Please see Figure 5 The figure shows Figure 4 A partially enlarged schematic diagram, specifically a schematic diagram of the guide groove 21 and the spring arm 22.

[0052] In this embodiment, the specific mounting structure of the mounting bracket 2 and the vehicle body mounting surface 3 is as follows: Figure 3-5 As shown: A lens hole 32 is provided on one side wall of the mounting groove 31, through which the lens of the camera module 1 can pass. The vehicle positioning part 34 is distributed on the adjacent two sides of the side wall where the lens hole 32 is located. The mounting bracket 2 slides towards the lens hole 32 through the guide groove 21 to push the lens 13 of the camera module 1 out of the lens hole 32.

[0053] The mounting bracket 2 is L-shaped. The back cover 11 of the camera module 1 is fixedly connected to the vertical plate of the mounting bracket 2. Connecting plates 20 are provided on both sides of the horizontal plate of the mounting bracket 2, and guide grooves 21 are located on the connecting plates 20.

[0054] The spring arm 22 is arranged along the sliding direction of the guide groove 21. One end of the spring arm 22 is connected to the end of the guide groove 21 near the lens hole 32. The other end of the spring arm 22 is provided with a spring arm protrusion 221. The guide groove 21 and the end where the spring arm protrusion 221 is located are provided with a first positioning hole 28. During the sliding process, the mounting bracket 2 causes the vehicle positioning part 34 to slide to the first positioning hole 28, and is fixed by the spring arm protrusion 221 abutting against the vehicle positioning part 34.

[0055] Specifically, the guide groove 21 of the mounting bracket 2 is brought into contact with the vehicle body positioning part 34 and inserted. After the mounting bracket 2 is in complete horizontal contact with the vehicle body mounting surface 3, a certain force is applied to push the mounting bracket 2 forward along the guide groove 21 toward the lens hole 32. When it reaches the position of the spring arm protrusion 221, the spring arm 22 will be forced to open outward. Continue to push forward until the vehicle body positioning part 34 contacts the rear end of the first positioning hole 28 and stops. At the same time, the spring arm 22 disengages from the contact with the vehicle body positioning part 34 and returns to its original position, thus restricting the forward movement of the vehicle body positioning part 34.

[0056] In addition, a first screw hole 33 is provided on the side of the mounting groove 31 where the body positioning part 34 is located, and a second screw hole 23 corresponding to the first screw hole 33 is provided on the side of the guide groove 21 of the mounting bracket 2. After the mounting bracket 2 is slidably installed in the mounting groove 31 along the guide groove 21, it is fixed by the first fixing member 4 passing through the first screw hole 33 and the second screw hole 23.

[0057] Furthermore, the mounting bracket 2 is also provided with a drainage hole 24, which is used to drain the water generated by the camera module 1.

[0058] In this embodiment, since connecting plates 20 are provided on both sides of the horizontal plate of the mounting bracket 2, and the guide groove 21 is located on the connecting plate 20, the second screw hole 23 is also located on the connecting plate 20.

[0059] The guide grooves 21 and the second screw holes 23 on the connecting plates 20 on both sides of the mounting bracket 2 can be arranged opposite to each other or staggered. That is, the second screw hole 23 can be located at the first end of the guide groove 21 or at the second end of the guide groove 21. Alternatively, the second screw hole 23 on one side of the connecting plate 20 can be located at the first end of the guide groove 21, and the second screw hole 23 on the other side of the connecting plate 20 can be located at the second end of the guide groove 21.

[0060] Therefore, in this embodiment, the installation process of the mounting bracket 2 and the vehicle body mounting surface 3 is as follows: After the camera module 1 is directly fixedly connected to the mounting bracket 2, the mounting bracket 2 is sleeved on the vehicle body positioning part 34 through the guide groove 21. At this time, the connecting plate 20 of the mounting bracket 2 is in horizontal contact with the vehicle body mounting surface 3, and the lens 13 of the camera module 1 corresponds to the lens hole 32. The mounting bracket 2 is pushed towards the lens hole 32 through the guide groove 21 so that the lens 13 of the camera module 1 is pushed out of the lens hole 32. At the same time, the mounting bracket 2 slides along the guide groove 21 so that the vehicle body positioning part 34 slides to the first positioning hole 28, and is fixed by the spring arm protrusion 221 abutting against the vehicle body positioning part 34. Then, the mounting bracket 2 and the vehicle body mounting surface 3 are locked and fixed by the first fixing member 4 passing through the first screw hole 33 and the second screw hole 23.

[0061] Example 2

[0062] This embodiment discloses a vehicle-mounted camera mounting structure. Specifically, based on embodiment 1, it further discloses the connection structure between the camera module 1 and the mounting bracket 2.

[0063] Please see Figure 6 The figure shows a schematic diagram of a camera module structure for a vehicle-mounted camera installation structure provided in this embodiment.

[0064] Please see Figure 7 The figure shows a schematic diagram of the camera module and mounting bracket assembly structure of a vehicle-mounted camera installation structure provided in this embodiment.

[0065] In this embodiment, as Figure 6 As shown, please continue to refer to Figure 4The vertical plate of the mounting bracket 2 has a second positioning hole 26, a third screw hole 27, and a first through hole 25. The rear cover 11 of the camera module 1 has a positioning post 111 that passes through the second positioning hole 26, a fourth screw hole 112 that matches the third screw hole 27, and a wiring harness 12 of the camera module 1 that passes through the first through hole 25 and is fixedly connected to the rear cover 11. The wiring harness 12 of the camera module 1 passes through the first through hole 25 and the positioning post 111, is embedded in the second positioning hole 26, and is then fixedly connected to the mounting bracket 2 by a second fixing member 5 that passes through the third screw hole 27 and the fourth screw hole 112. The installed camera module 1 and mounting bracket 2 are as follows... Figure 7 As shown.

[0066] Specifically, the end of the wiring harness 12 of the camera module 1 is aligned with the vertical plate of the mounting bracket 2, and the wiring harness 12 of the camera module 1 is passed through the first through hole 25 in the direction of the vertical plate of the mounting bracket 2. At the same time, the second positioning hole 26 is aligned with the positioning post 111 and inserted. Then, the camera module 1 is locked and fixed to the mounting bracket 2 by the second fixing member 5 passing through the third screw hole 27 and the fourth screw hole 112.

[0067] Example 3

[0068] This embodiment addresses the problems of existing self-heating cameras, such as the common connection method for connecting the power supply and output signal of the heating lens, which includes a power connection port for the lens heating element and a signal transmission connection port for the camera, requiring two connector ports, not only occupying space in the camera module but also making the assembly process of the camera module more complicated. Therefore, a camera module is disclosed.

[0069] Figure 8-10 An exploded view of a camera module provided by the present invention is shown.

[0070] This embodiment discloses a camera module that can be installed using the vehicle-mounted camera mounting structure described in any of embodiments 1-2 above. The camera module 1 is as follows... Figure 8-10 As shown, it includes: a lens 13 with a heating element 14, a front cover 15, a rear cover 11, a sensor PCBA 16, a power PCBA 17, and a wiring harness 12. The lens 13 is laser-welded to the front cover 15, the front cover 15 is fixedly connected to the rear cover 11, the sensor PCBA 16 is connected to the front cover 15, the heating element 14 passes through the front cover 15 and is connected to the sensor PCBA 16, the power PCBA 17 is installed in the rear cover 11 and is connected to the sensor PCBA 16, and the wiring harness 12 is fixedly connected to the rear cover 11 and passes through the rear cover 11 and is connected to the power PCBA 17.

[0071] Additionally, a first connector 162 and a second connector 163 are provided on the opposite side of the sensor PCBA16 and the power PCBA17, a third connector 171 is provided on the opposite side of the power PCBA17 and the sensor PCBA16, and a fourth connector 173 is provided on the opposite side of the power PCBA17 and the sensor PCBA16.

The second connector 163 is connected to the third connector 171, and the fourth connector 173 is connected to the wire harness 12.

[0072] Therefore, a third through hole 151 is provided on the front cover 15 so that the heating element 14 can pass through.

[0073] In this preferred embodiment, the fourth connector 173 integrates the power port of the heating element 14 and the camera transmission signal port, with the wiring harness 12 matching the fourth connector 173. Integrating the power port of the heating element 14 and the camera transmission signal port into a single connector reduces the types and quantity of materials used in the camera module, while significantly optimizing the camera module assembly process (including SMT). Most importantly, by using the integrated connector, namely the fourth connector 173, the space occupied by the power PCBA 17 and the entire camera module is greatly reduced, allowing the heated camera module to be made almost the same size as a conventional camera, further expanding its application range.

[0074] In this embodiment, the mounting structure of each component is as follows: the lens 13 and the front cover 15 are connected by laser welding to achieve fixation and sealing. A second mounting platform 152 is provided at the opposite end of the front cover 15 and the rear cover 11. The sensor PCBA 16 is fixedly mounted on the second mounting platform 152 of the front cover 15 with glue 161. After the sensor PCBA 16 is installed, the heating element 14 on the lens 13 passes through the third through hole 151 on the front cover 15 and contacts the first connector 162 on the sensor PCBA 16. A first mounting platform 113 is provided at the opposite end of the rear cover 11 and the front cover 15. The power PCBA 17 can be mounted on the first mounting platform 113 on the rear cover 11 with glue, or it can be mounted on the first mounting platform 113 on the rear cover 11 with the third fastener 172. In addition, a second through hole 114 is provided at the bottom of the rear cover 11. The wire harness 12 can pass through the second through hole 114 on the rear cover 11 and connect with the power PCBA 16. The fourth connector 174 on PCBA17 is connected, and the wiring harness 12 is also fixedly mounted on the rear cover 11 by the fourth fastener 121. A sealing ring 18 is provided between the front cover 15 and the rear cover 11, and then the connection is fixed by laser welding to achieve sealing and fixation. The assembled camera module is as follows. Figure 11-13 As shown.
