Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted camera protection, and in particular to a vehicle-mounted AI camera module with a waterproof function. Background Art

[0002] The advancement of automobile technology has entered a new stage, from traditional mechanical drive to electronic and intelligent development. Modern cars not only have more efficient power systems and comfort performance, but also improve driving safety and convenience through advanced driver assistance systems and external monitoring functions, which rely on high-precision AI cameras.

[0003] AI cameras are usually installed inside and outside the car. Cameras installed outside the car are usually used for guidance in vehicle assisted driving and monitoring after the car is parked. Since they are installed outside the car, the cameras are usually exposed to some bad weather, such as rain, dust and other weather. In order to ensure that the camera can work normally, the existing device usually places the camera in a closed protective shell. One side of the protective shell is installed with light-transmitting glass, so that the camera can monitor outward through the glass. Although it can play a certain waterproof function, rainwater often contains impurities, and dust will adhere to the glass surface during driving. Water and dust attached to the glass will reduce the clarity of the glass, making it impossible for the camera to perform high-precision monitoring outward through the glass.

[0004] In order to make a more accurate comparison, for example, Chinese patent publication number CN209330238U discloses a vehicle-mounted waterproof camera installation structure.

[0005] The lens comprises a lens mounted on a lens barrel connected to a front shell, adhesive is filled between the relative surfaces of the lens barrel and the front shell, and a filling groove is arranged on the relative surfaces of the lens barrel and the front shell to increase the sealing between the lens and the front shell.

[0006] However, the above waterproof installation structure still has some shortcomings in actual use:

[0007] 1. The above-mentioned installation structure can only seal the lens barrel through the lens to achieve the waterproof function of the internal camera. This installation method can only seal a single lens, and the existing vehicle-mounted camera module is usually composed of multiple cameras to achieve AI monitoring and real-time pathfinding functions. Therefore, the above-mentioned device is not suitable for the installation of multiple cameras and has low applicability.

[0008] 2. The camera in the above-mentioned installation structure monitors the external environment in real time through the lens. If it is raining or dusty, a mixture of dust and rain may adhere to the surface of the lens, which indirectly leads to a decrease in the light transmittance of the lens, making it impossible for the camera to perceive the outside world in real time through the lens. In addition, since the above-mentioned installation structure installs the lens on the lens barrel by glue, when the internal camera fails and needs to be replaced, the glue needs to be removed before the lens can be removed, which is more troublesome and further reduces its applicability.

[0009] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing waterproof lens modules. Summary of the invention

[0037] The following combination Figures 1 to 10 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0038] The embodiment of the present application discloses a vehicle-mounted AI camera module with a waterproof function, which explains that the vehicle-mounted AI camera module with a waterproof function is mainly used in the process of waterproofing the car camera module. In terms of technical effect, it can separate rainwater and the camera lens by providing a protective film, and can also wipe the movable protective film to wipe off the dirt attached to the outside of the protective film, so that the camera can always accurately detect the external environment through the protective film; further, when the camera module fails or the protective film is worn and needs to be replaced, the present invention can use a quick-release design to facilitate maintenance personnel to remove the protective film and the camera module.

[0039] Example 1: Reference Figure 1 and Figure 2 As shown, it includes a protection block 1, an installation cavity 10, a center plate 11, a camera module 12, an annular groove 13 and a protection unit 2. The protection block 1 is provided with an installation cavity 10, and a center plate 11 is slidably arranged on the inner wall of the installation cavity 10. A push spring (not shown in the figure) is arranged between one side of the center plate 11 and the inner wall of the installation cavity 10, and the center plate 11 can slide in the front and rear directions in the installation cavity 10.

[0040] In the initial state, the push spring is always placed to press the center plate 11 against the front end of the installation cavity 10; a number of camera modules 12 are installed on the center plate 11, and the center plate 11 can drive the camera module 12 to move. The camera module 12 is used to monitor the outside of the car in real time, and the camera module 12 belongs to a known technology, so it is not described in detail in this implementation process; an annular groove 13 with one end extending to the outside is provided inside the protection block 1, and one side of the annular groove 13 is connected with the installation cavity 10, and a protection unit 2 for waterproofing the camera module 12 is provided in the annular groove 13, and the protection unit 2 achieves waterproofing of the camera module 12 by blocking the annular groove 13.

[0041] Continue to refer to Figure 1 and Figure 2 As shown, a protection unit 2 is used to provide waterproof protection for the camera module 12; specifically, the protection unit 2 includes an annular groove 13, a protective film 21, a rolling ball 22, an arc plate 23 and a limit plate 24, a rectangular groove 20 is opened on one side of the protection block 1 and is connected with the annular groove 13, a protective film 21 is slidably arranged in the annular groove 13, the protective film 21 can move along the annular groove 13 when driven by an external force, and the protective film 21 is made of a light-transmitting material, so the camera module 12 can monitor the external environment through the installation cavity 10, the protective film 21 and the rectangular groove 20, and the protective film 21 can prevent rainwater and external dust from entering the installation cavity 10.

[0042] Rolling balls 22 that are tightly attached to the outer side of the protective film 21 are rotatably arranged on the inner walls of the four sides of the annular groove 13. When the protective film 21 moves, the rolling balls 22 can be driven to rotate, thereby indirectly avoiding friction between the protective film 21 and the inner wall of the annular groove 13, which may reduce the service life of the protective film 21.

[0043] The arc plate 23 is arranged on the inner wall of the annular groove 13 and is distributed at the four corners of the annular groove 13 and is tightly attached to the inner wall of the protective film 21. The inner wall of the annular groove 13 is also provided with several limiting plates 24 distributed along its extension section and tightly attached to the inner wall of the protective film 21. The arc plate 23 and the limiting plate 24 respectively limit and support the bent inner wall and the straight inner wall of the protective film 21, so that the protective film 21 will not be deformed when moving, avoiding friction between the inner diameter of the protective film 21 and the inner wall of the annular groove 13.

[0044] The arc plate 23 and the limit plate 24 are both slidably connected to the inner wall of the annular groove 13. The arc plate 23 and the limit plate 24 are both provided with a return spring (not shown in the figure) between the inner wall of the annular groove 13. In the initial state, the return spring pushes the corresponding arc plate 23 and the limit plate 24 to press against the inner wall of the protective film 21 to limit the position. When the protective film 21 is installed, the arc plate 23 and the limit plate 24 are retracted by squeezing the inner diameter of the protective film 21, so that the protective film 21 can enter the annular groove 13, and then the arc plate 23 and the limit plate 24 are driven by the corresponding return spring to press against the inner wall of the protective film 21 to limit the position.

[0045] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rectangular cavity 30 is opened inside the protective block 1, and a sliding unit 3 is arranged in the rectangular cavity 30 for driving the protective film 21 to move in the annular groove 13; specifically, the sliding unit 3 includes a rectangular cavity 30, a sliding frame 31, a driving ball 32, a driven shaft 33, a driven plate 34, a driving annular groove 35, a belt 36, a push plate 37 and a push spring rod 38, four sliding grooves are respectively opened on the four inner walls of the installation cavity 10, and one end of the sliding groove is connected with the annular groove 13, and a sliding frame 31 is slidably arranged in the sliding groove, that is, the sliding frame 31 can slide in the corresponding sliding groove, and one end of the sliding frame 31 can slide into the annular groove 13.

[0046] A driving ball 32 tightly attached to the inner wall of the protective film 21 is rotatably provided at one end of the sliding frame 31, and the driving ball 32 corresponds to the rolling ball 22. The sliding frame 31 can drive the corresponding driving ball 32 to move synchronously, and the driving ball 32 can rotate under the limit of the corresponding sliding frame 31. At this time, the rolling ball 22 and the driving ball 32 are pressed against both sides of the protective film 21. Therefore, when the driving ball 32 rotates, the protective film 21 can be driven to move in the annular groove 13 through the friction of its outer side.

[0047] A driven shaft 33 is rotatably provided on the inner wall on the other side of the sliding frame 31, and a driven plate 34 is sleeved on the outer side of the driven shaft 33. The driven plate 34 can drive the corresponding driven shaft 33 to rotate; driving ring grooves 35 are provided on the outer sides of the driven plate 34 and the driving ball 32, and belts 36 are sleeved between the corresponding driving ring grooves 35. The driving ring grooves 35 are used to limit the belts 36. When the driven plate 34 rotates, the corresponding driving ball 32 can be driven to rotate synchronously through the belts 36.

[0048] A push plate 37 is provided on one side of the sliding frame 31, and push spring rods 38 are provided on the inner walls of the four sides of the rectangular cavity 30, and the telescopic ends of the push spring rods 38 are connected to the corresponding push plates 37. In the initial state, the push spring rods 38 push the corresponding sliding frame 31 to move in the direction away from the annular groove 13 through the push plates 37, that is, in the initial state, the driving ball 32 will not be tightly attached to the protective film 21. Only when the sliding frame 31 is driven by external force, the sliding frame 31 will drive the corresponding driving ball 32 to contact the inner wall of the protective film 21.

[0049] Continue to refer to Figure 5 As shown, a driving assembly 4 for driving the driven plate 34 to rotate is also provided in the rectangular cavity 30; specifically, the driving assembly 4 includes a sliding groove 40, a sleeve 41, a motor 42, a driving cone plate 43, a limiting column 44, a pushing spring 45 and a pulling handle 46. The sliding groove 40 is opened at the upper end of the protection block 1, and a sleeve 41 is slidably provided in the sliding groove 40, and the sleeve 41 can slide in the sliding groove 40 in the up and down directions; a motor 42 is provided inside the sleeve 41, and a driving cone plate 43 is provided at the output end of the motor 42 through the outer wall of the lower end of the sleeve 41, and the motor 42 can drive the driving cone plate 43 to rotate.

[0050] The outer side of the driving cone plate 43 is in contact with the driven plate 34. When the driving cone plate 43 rotates, it can drive the driven plate 34 to rotate, so that the driven plate 34 can indirectly drive the driving ball 32 to rotate. When the sleeve 41 indirectly drives the driving cone plate 43 to descend in the direction of the driven plate 34, the driving cone plate 43 can resist the driven plate 34, so that the driven plate 34 can indirectly drive the sliding frame 31 to move in the direction of the annular groove 13. When the driving cone plate 43 is driven by the sleeve 41 to move upward, the sliding frame 31 will be indirectly driven by the corresponding push spring rod 38 and will no longer be located in the annular groove 13.

[0051] A fixed through slot is provided at the upper end of the middle plate 11, and a limiting column 44 is provided on one side of the driving cone plate 43, one end of which passes through the outer wall of the rectangular cavity 30 and the installation cavity 10 and is located in the fixed through slot, and a push spring 45 is provided on one side of the driving cone plate 43, and the other side of the push spring 45 contacts the inner wall of the rectangular cavity 30, and a pulling handle 46 is provided on one end of the sleeve 41 located outside the protective block 1, and the limiting column 44 can be driven to move by manually pulling the handle 46, and the push spring 45 is in the initial state. The driving cone plate 43 can be driven not to contact the driven plate 34. Only when an external force is applied to the pulling handle 46 to shrink the pushing spring 45, the outer side of the driving cone plate 43 can contact the outer side of the driven plate 34. When the driving cone plate 43 moves, it can drive the limiting column 44 to move synchronously. The limiting column 44 can limit the center plate 11 through the fixed through groove, so that the center plate 11 will not be driven by the placement push spring to drive the camera module 12 to move to the front end of the installation cavity 10 at this time.

[0052] Reference Figure 6 As shown, the upper end of the protection block 1 is provided with a blocking assembly 5 for blocking the annular groove 13; specifically, the blocking assembly 5 includes a mounting groove 50, a blocking plate 51 and a fixing bolt 52, and the four mounting grooves 50 are respectively provided on the four corners of the protection block 1, and the blocking plate 51 of the U-shaped structure is located at the upper end of the protection block 1, and the four sides of the blocking plate 51 are in contact with the upper end of the blocking plate 51, and the inner wall of the blocking plate 51 is in contact with the pulling handle 46, and the blocking plate 51 is used to block the annular groove 13. 3 is used for blocking to prevent rainwater from falling into the annular groove 13, and the blocking plate 51 can indirectly apply pressure to the sleeve 41 by pulling the handle 46, so that the sleeve 41 can indirectly drive the outer side of the driving cone plate 43 to contact the driven plate 34; the four corners of the blocking plate 51 are slidably penetrated by fixing bolts 52 with one end located in the corresponding mounting groove 50, and the fixing bolts 52 are threadedly connected to the mounting groove 50, and the blocking plate 51 can be fixed to the upper end of the protection block 1 through the fixing bolts 52.

[0053] In the initial situation, the blocking plate 51 indirectly drives the driving cone plate 43 to contact the driven plate 34, driving the driven plate 34 to rotate. When the protective film 21 needs to be replaced, the fixing bolt 52 is unscrewed to remove the blocking plate 51. At this time, the arc-shaped through groove is no longer resisted, and the push spring 45 will push the driving cone plate 43 to move upward and no longer resist the driven plate 34, so that the sliding frame 31 can drive the driving ball 32 to no longer contact the inner wall of the protective film 21, and the protective film 21 can be smoothly pulled out of the annular groove 13, and the new protective film 21 can be inserted into the annular groove 13 again.

[0054] When the camera module 12 is to be replaced, a new protective film 21 is first inserted into the annular groove 13. At this time, even if the driving cone plate 43 is no longer in contact with the driven plate 34, the limiting column 44 is long, and its end is still located in the fixed through groove, and the middle plate 11 continues to be limited. At this time, the sleeve 41 is pulled upward by pulling the handle 46, which can indirectly drive the limiting column 44 to no longer be located in the fixed through groove, and the middle plate 11 can be placed with a push spring to drive it to move forward, and then replace it. Replace or repair the camera module 12, then push the center plate 11 to the initial position, put down and pull the handle 46, indirectly allowing the limit column 44 to continue to be inserted into the fixed through groove to limit the center plate 11, and then insert the new protective film 21 into the annular groove 13, and then fix the sealing plate 51 to the upper end of the protective block 1 by the fixing bolts 52, so that the driving cone block can contact the driven plate 34, and the sliding frame 31 can continue to drive the corresponding driving ball 32 to contact the inner diameter of the protective film 21.

[0055] It should be explained that the reason for limiting the center plate 11 in the middle of the installation cavity 10 is that when replacing the protective film 21, in order to prevent the camera module 12 from being too close to the rectangular groove 20 and the normal camera module 12 from being damaged due to contact with people or objects, the center plate 11 is limited in the middle of the installation cavity 10 in the initial state, and the center plate 11 is moved to the front end of the installation cavity 10 when the camera module 12 needs to be repaired.

[0056] Reference Figure 7 , Figure 8 and Fig. 9 As shown, a discharge groove is symmetrically provided on one side of the protective block 1, and the discharge groove corresponds to the limit plate 24 on one side, and an erasing unit 6 for erasing the dirt on the outside of the protective film 21 is arranged in the discharge groove; specifically, the erasing unit 6 includes a rotating shaft 60, a spiral blade 61, a wiping block 62, a semi-cylinder 63, a synchronous shaft 64, a telescopic rod 65 and a swing plate 66, the rotating shaft 60 is rotatably arranged on the inner wall of the discharge groove, a spiral blade 61 is arranged on the outside of the rotating shaft 60, a wiping block 62 attached to the outside of the protective film 21 is arranged on the outside of the spiral blade 61, and one end of the discharge groove passes through the lower end of the protective block 1, the rotating shaft 60 can drive the spiral blade 61 to rotate, and the spiral blade 61 can drive the wiping block 62 to rotate synchronously, and when the wiping block 62 rotates, the dirt on the outside of the protective film 21 can be wiped off and discharged from the bottom of the discharge groove.

[0057] The lower end of the protection block 1 is also symmetrically provided with a semi-cylinder 63 of a U-shaped structure, and the two semi-cylinders 63 correspond one to one to the symmetrically distributed discharge grooves. The lower end of the protection block 1 is also rotatably provided with two synchronous shafts 64 corresponding to the semi-cylinders 63. A telescopic rod 65 is provided on the outer side of the synchronous shaft 64. The telescopic end of the telescopic rod 65 is provided with a swing plate 66 that is in contact with the inner wall of the semi-cylinder 63. When the synchronous shaft 64 rotates, the swing plate 66 can be driven by the telescopic rod 65 to swing along its axis.

[0058] In the initial state, the swing plate 66 is located inside the semi-cylinder 63, driving the telescopic end of the telescopic rod 65 to retract. When the swing plate 66 swings out of the inner wall of the semi-cylinder 63, it can be pushed toward the discharge groove under the push of the telescopic rod 65, and the dirt adhered to the lower end of the discharge groove is pushed out of the bottom of the protective block 1 to prevent the dirt from adhering to the bottom of the discharge groove; and the two synchronous shafts 64 are connected by belt transmission, and the synchronous shaft 64 and the corresponding rotating shaft 60 are also connected by belt transmission, that is, the synchronous shafts 64 on both sides can rotate synchronously, that is, when the synchronous shaft 64 rotates, it can also drive the corresponding rotating shaft 60 to rotate synchronously.

[0059] If there is dirt attached to the surface of the protective film 21, which affects the monitoring accuracy of the camera module 12, the driving component 4 can provide power to the sliding unit 3, so that the sliding unit 3 can drive the protective film 21 to move, and the dirty part of the protective film 21 will move to the erasing unit 6, and the dirt on the surface of the moisturizing film will be wiped off by the wiping block 62. Since the protective film 21 is always moving, the present invention provides two groups of erasing units 6 to synchronously clean the surface of the protective film 21 to avoid the situation of unclean wiping.

[0060] Example 2: Reference Figure 3 and Fig.10 As shown, on the basis of the first embodiment, in order to be able to drive the rotating shaft 60 and the synchronous shaft 64 to rotate, a transmission assembly 7 for transmitting the power of the motor 42 to the synchronous shaft 64 is arranged inside the middle plate 11; specifically, the transmission assembly 7 includes a transmission shaft 1 70, a transmission shaft 2 71, a driving groove 72 and a driving key 73, the transmission shaft 1 70 is rotatably arranged inside the fixed through groove, and the lower end of the fixed block is also rotatably penetrated by the transmission shaft 2 71, the upper and lower ends of the transmission shaft 1 70 are symmetrically provided with driving grooves 72, the limiting column 44 and one end of the transmission shaft 2 71 are both provided with a driving key 73 located in the corresponding driving groove 72, and the transmission shaft 2 71 is connected to the synchronous shaft 64 on one side by a belt drive.

[0061] That is, the limit column 44 can rotate synchronously with the driving cone plate 43. When the limit column 44 rotates, it can drive the transmission shaft 1 70 to rotate in the fixed through groove through the corresponding driving key 73 and the driving groove 72. When the transmission shaft 1 70 rotates, it can also drive the transmission shaft 2 71 to rotate synchronously through the corresponding driving groove 72 and the driving key 73. When the transmission shaft 2 71 rotates, it can drive the synchronization shaft 64 on one side to rotate through the belt drive.

[0062] When the intermediate plate 11 moves in the installation cavity 10 , the corresponding driving key 73 will be separated from the driving slot 72 . After the intermediate plate 11 returns to the initial position, the driving key 73 will be inserted into the corresponding driving slot 72 again.

[0063] During operation: the first step is to install the camera module 12 on the central plate 11, and then insert the protective film 21 into the annular groove 13, and then drive the driving component 4 to limit the central plate 11 through the blocking component 5, and the driving component 4 simultaneously drives the sliding unit 3 to limit the protective film 21. The protective film 21 can protect the camera module 12 from water and dust.

[0064] Step 2: During use, if there is dirt attached to the surface of the protective film 21, which affects the monitoring accuracy of the camera module 12, the driving component 4 can provide power to the sliding unit 3 so that the sliding unit 3 can drive the protective film 21 to move, and the dirty part of the protective film 21 will move to the erasing unit 6.

[0065] Step 3: The transmission assembly 7 can transmit the rotational force of the motor 42 to the erasing unit 6, so that the erasing unit 6 can operate to erase the dirt on the surface of the protective film 21 and discharge it to the outside of the protective block 1.

[0066] Step 4: If the protective film 21 and the camera module 12 need to be replaced, remove the blocking assembly 5, first remove the protective film 21, then remove the camera module 12 from the center plate 11, and then install the new camera module 12 on the center plate 11, and then place the new protective film 21 in the annular groove 13, and install the blocking assembly 5 on the protective block 1, so that the driving assembly 4 and the sliding unit 3 limit the center plate 11 and the protective film 21 respectively.
