In order to avoid the dust and the like outside entering the accommodation cavity through the lifting opening 13, a convex table is convexly arranged around the lifting opening 13 on the side of the lifting opening 13 towards the accommodation cavity, the sealing ring 14 is fixedly connected on the convex table, and the sealing ring 14 is always blocked between the camera 3 and the convex table for dustproof and waterproof. The sealing ring 14 is made of elastic materials such as silica gel, rubber and the like. The sealing ring 14 is placed in the mold during the injection molding process of the lower shell 11 and is integrally formed with the lower shell 11, so as to reduce the assembly process of the sealing ring 14. The extension plate 113 extends along the lifting direction away from the first side plate 112 after being bent and extended from the side of the bottom plate 111. The extension plate 113 and the first side plate 112 both extend towards the same side in the thickness direction. The top space is left between the first side plate 112 and the extension plate 113 away from the side of the bottom plate 111, and the side space is formed between the two side edges of the bottom plate 111 along the length direction and the first side plate 112 and the extension plate 113, so as to leave the space for buckling of the upper shell 12. The connecting hole 114 for connecting with the central control screen is opened on the support plate of the extension plate 113, the connecting hole 114 can be a threaded hole or a conventional round hole, and is connected with the central control screen by using a screw or a bolt.

The connecting columns 15 are divided into main connecting columns 151 and secondary connecting columns 152, and the first positioning convex column 153 with a smaller diameter than the connecting column 15 is convexly arranged on the top end of one part of the secondary connecting columns 152 (i.e. the end away from the bottom plate 111). The lower shell 11 comprises a top plate 121 for buckling at the top space and a second side plate 122 bent and extended from the two sides of the top plate 121 along the length direction, the two sides of the top plate 121 along the lifting direction are supported on the first side plate 112 and the extension plate 113 when buckling on the top space, so as to block the top space and support each other to ensure stability; the two second side plates 122 are used for buckling at the two side spaces to surround the accommodation cavity.A second threaded slot hole 1211 is formed on the top plate 121 at a position corresponding to each main connecting column 151. A screw is used to screw into each corresponding second threaded slot hole 1211 and first threaded slot hole 154, thereby connecting the upper shell 12 and the lower shell 11. To improve the stability and firmness of the connection between the shell 1 and the central control screen, a buckle 16 is arranged on the top plate 121 for clamping cooperation with the central control screen. The buckle 16 includes a groove recessed on the top plate 121 and a protrusion formed on one side of the groove. Only one side of the protrusion is connected, and the other side is spaced from the groove. A moving space is formed between the protrusion and the groove for the clamping structure on the central control screen to enter. After passing through the moving space, the clamping structure is blocked by the protrusion to achieve clamping.

[0032] Please refer to Figures 2 to 3 , Figure 5 , Figures 6 to 8 , The lifting mechanism includes a base 21 fixedly connected in the shell 1 and a lifting structure 22 connected to the base 21. The base 21 is used to support the lifting structure 22, and the lifting structure 22 is used to drive the camera 3 to move. In another embodiment, the lifting mechanism includes an electric push rod mounted in the shell 1. The electric push rod is arranged in the lifting direction and the output shaft is arranged towards one side of the lifting port 13. The camera 3 is connected to the output shaft of the electric push rod to move along the lifting direction by the electric push rod.

[0033] In this embodiment, the base 21 is a square structure with a certain thickness, and the thickness is less than the depth or thickness of the accommodating cavity so that it can be arranged in the accommodating cavity. Wings 211 are formed on both sides of the base 21 in the length direction and extend backward. At least three secondary connecting columns 152 are arranged on the bottom plate 111 of the lower shell 11 at positions corresponding to the wings 211. At least one secondary connecting column 152 has a first positioning protrusion 153. Third threaded slot holes 212 and first positioning holes 213 are formed on the wings 211 at positions corresponding to each secondary connecting column 152. The first positioning protrusion 153 penetrates into the first positioning hole 213. The third threaded slot hole 212 and the corresponding first threaded slot hole 154 are connected and fixed by a screw to connect the base 21 to the lower shell 11. A fitting cavity 23 is recessed on the side of the base 21 away from the bottom plate 111 in the thickness direction. The lifting structure 22 is mounted in the fitting cavity 23. A movable port 24 is formed on the base 21 at a position corresponding to the lifting port 13 in the lifting direction and communicating with the fitting cavity 23. The size of the movable port 24 is greater than that of the lifting structure 22 and is opposite to the lifting port 13 in the lifting direction, so that the lifting structure 22 can pass through the movable port 24 and the lifting port 13 in sequence in the lifting direction.

[0034] In the content defined in the embodiment, the lifting structure 22 comprises two sliding shafts 221 arranged in parallel in the matching cavity 23 and extending along the lifting direction, two sliding blocks 222 respectively sleeved on the two sliding shafts 221 and sliding along the lifting direction, a supporting block 223 connected between the two sliding blocks 222, a threaded rod 224 arranged in the matching cavity 23 and rotating along the lifting direction, and a driving member 225 mounted on the base 21 and used for driving the threaded rod 224 to rotate forward and backward. The supporting block 223 has a supporting surface, the camera 3 is connected to the supporting block 223, and the driving member 225 is electrically connected to the main circuit board 4. One of the sliding blocks 222 is close to the threaded rod 224 and is sleeved on the threaded rod 224 and moves along the lifting direction. The driving member 225 is used for driving the threaded rod 224 to rotate forward, thereby driving the sliding block 222 and the supporting block 223 to move along the lifting direction towards one side of the lifting opening 13, so that the camera 3 gradually rises out of the lifting opening 13 and is used for shooting. When the shooting is completed, the driving member 225 drives the threaded rod 224 to rotate reversely to drive the sliding block 222 and the supporting block 223 to move along the lifting direction towards the matching cavity 23, until the camera 3 is retracted into the accommodating cavity, thereby realizing the lifting control of the camera 3.

[0035] The two slide shafts 221 and the threaded rod 224 are arranged along a length direction perpendicular to the lifting direction and the thickness direction in sequence, the matching cavity 23 includes a main cavity and a secondary cavity located on one side of the main cavity along the length direction, wherein the size of the main cavity in the lifting direction is larger than that of the secondary cavity. A first through hole is formed on each side of the secondary cavity along the lifting direction, and a micro bearing is arranged at each first through hole. The two ends of the threaded rod 224 pass through and are connected to the two micro bearings, so that the threaded rod 224 is rotatably arranged in the secondary cavity and can rotate around its axis. The two slide shafts 221 are arranged in the main cavity, and an L-shaped abutting surface 231 is formed between the secondary cavity and the main cavity on the side of the secondary cavity close to the matching structure along the lifting direction. One of the slide blocks 222 close to the threaded rod 224 is provided with a connecting block 226 threaded on the threaded rod 224, and the connecting block 226 abuts against the abutting surface 231 when the camera 3 is located at the initial position, thereby limiting the initial position of the slide block 222, avoiding excessive movement of the slide block 222 when the driving member 225 drives the threaded rod 224 to rotate in the opposite direction, and affecting the use of the camera 3. In order to ensure the convenient use of the camera 3, the end face of the camera 3 away from the support block 223 is located in the lifting port 13 when the connecting block 226 abuts against the abutting surface 231, thereby being located at the initial position, avoiding the end face of the camera 3 away from the support block from being separated from the lifting port 13, and the situation that the camera 3 is difficult to align and pass into the lifting port 13 when the camera 3 is used next time. The cooperation between the abutting surface 231, the connecting block 226 and the end face of the camera 3 improves the convenience of operation. Second through holes are formed on the main cavity corresponding to the positions of the slide shafts 221 along the lifting direction, and the two ends of each slide shaft 221 pass through the corresponding second through hole to connect the slide shaft 221. The two ends of the slide shaft 221 can be clamped into the second through hole by using glue or connecting a squeezing block matched with the second through hole to complete the limiting of the slide shaft 221. The two slide shafts 221 are separately arranged on the two sides of the movable port 24. The two slide blocks 222 are connected by the support block 223 to avoid overturning of the slide blocks 222 and facilitate connection with the camera 3. The driving member 225 can be a servo motor or other device with an output shaft capable of rotating in both directions and is fixedly connected to one side of the base 21 away from the movable port 24. The output shaft of the driving member 225 is coaxially connected to the threaded rod 224 to drive the threaded rod 224 to rotate when in operation. The driving member 225 is electrically connected with a secondary circuit board 25, and the secondary circuit board 25 is electrically connected to the main circuit board 4.

The rear shell 33 is provided with a support column 332 at a position corresponding to the first screw hole 342 for supporting the front shell 34, and the support column 332 is provided with a second screw hole in which the locking screw 37 is screwed. The locking screw 37 is located inside the transparent cover plate 39 and is screwed in the first screw hole 342 and the second screw hole, and the head of the locking screw 37 is located in the first screw hole 342 so as not to affect the cooperation of the transparent cover plate 39 with the embedding groove 341. In this way, the locking screw 37 is hidden inside the transparent cover plate 39 and is installed along the thickness direction perpendicular to the transparent cover plate 39. The transparent cover plate 39 is made of transparent material such as glass, so that the appearance is more beautiful, the appearance consistency is good, and the assembly efficiency is relatively higher. The first screw hole 342 is formed at a middle position of the front shell 34 along the lifting direction, so that the locking can be performed with fewer screws. The lens hole 343 is arranged on a side close to the lifting port 13 relative to the first screw hole 342. The extension 32 is formed from a side of the front shell 34 away from the lifting port 13 and is sheet-shaped and thinner than the front shell 34. Two third screw holes 321 are formed in the support surface of the extension 32 along the thickness direction. Two bosses 2231 slightly higher than the support surface are protruded on the support surface at positions corresponding to the two third screw holes 321. Fourth screw holes are formed in the bosses 2231. The extension 32 is connected with the lifting mechanism by being screwed in the third screw holes 321 and the fourth screw holes. In order to prevent the camera 3 from being deflected during assembly, two second positioning protrusions 2232 are protruded on the support block 223, and two second positioning holes 322 are formed in the extension 32. During assembly, the second positioning holes 322 of the extension 32 are first sleeved on the second positioning protrusions 2232, and the third screw holes 321 are aligned with the fourth screw holes, and then fixed by screws. The bosses 2231 space the extension 32 from the support block 223. In order to ensure the arrangement of the flexible circuit board 36, spaces for the flexible circuit board 36 to pass through are provided between the two second positioning protrusions 2232 and the two bosses 2231.

[0039] In the content defined by the embodiment, the lens module 35 includes a photosensitive chip electrically connected to the flexible circuit board 36, a lens seat 352 mounted on the arrangement area 331 and facing the flexible circuit board 36, and a lens 353 mounted on the lens seat 352, the lens 353 being aligned with the lens hole 343, one end of the camera head 3 having the lens hole 343 being defined as the shooting end 31, and the buffer foam 38 being arranged between the lens 353 and the front shell 34. In use, the shooting end 31 will pass through the lifting opening 13 to extend out of the shell 1.

[0040] In order to avoid the camera head 3 from being affected during the lifting process, the flexible circuit board 36 is used. The flexible circuit board 36 includes a connecting segment 361 connected to the camera head 3, a bending segment 362 connected to the connecting segment 361 and located outside the extension 32, and a fixed segment 363 connected to the bending segment 362, the fixed segment 363 being provided with an electrical connector 364 electrically connected to the main circuit board 4. The rear shell 33 is provided with a notch on the side away from the lifting opening 13 for the flexible circuit board 36 to pass through, and the connecting segment 361 electrically connected to the photosensitive chip passes through the notch and adheres to the extension 32.

At the same time, the bending segment 362 and the camera head 3 are sequentially distributed along the lifting direction, thereby reducing the overall thickness without affecting the distribution of the flexible circuit board 36. In order to facilitate the distribution of the bending segment 362, an active cavity 232 for accommodating the bending segment 362 extending therein is formed between the two sliding blocks 222 and the base 21, the active cavity 232 being adapted to the bending segment 362 and communicating with the main cavity, the flexible circuit board 36 being capable of moving in the active cavity 232, and the gap between the active cavity 232 and the flexible circuit board 36 in the length direction being smaller than the width of the flexible circuit board 36 to prevent the flexible circuit board 36 from being deflected greatly, thereby playing a certain limiting role and enabling the flexible circuit board 36 to move substantially only in the lifting direction.

[0041] In the embodiment, the support table 233 is formed on the bottom wall of the movable cavity 232, and a guide inclined surface 234 is formed on the side of the support table 233 close to the camera 3. The first flat portion 3622 of the bending section 362 of the flexible circuit board 36 is abutted against the support table 233 when the camera 3 is in the initial position. When the camera 3 is lifted out of the lifting opening 13 under the driving of the lifting mechanism, the bending section 362 of the flexible circuit board 36 is deformed and moved towards the side of the lifting opening 13 and is pulled due to the restriction of the support table 233 and the main circuit board 4 and the movable cavity 232. The guide inclined surface 234 can guide the bending section 362 moving towards the side away from the lifting opening 13 in the lifting direction, so that the bending section 362 is more easily reset and the possibility of being jammed is reduced. During the resetting of the camera 3, the guide inclined surface 234 and the cooperating cavity 23 jointly form a resetting guide space 235, so that the bending section 362 can slide along the resetting guide space 235 to reset under the condition that the main circuit board 4 is fixed.

[0042] In the embodiment, the main circuit board 4 is fixed on the side of the base 21 close to the upper shell 12, and the position corresponding to the camera 3 is avoided. The second flat portion 3624 of the bending section 362 is abutted against the main circuit board 4 when the camera 3 is in the initial position, so that the main circuit board 4 supports the flexible circuit board 36 and reduces the possibility of deforming along the predetermined path.

[0043] The working mode of one of the embodiments of the central control screen lifting camera module is as follows: after the shell 1 is installed on the central control screen as a part of the central control screen and is electrically connected, the camera 3 is in the initial position, the sliding block 222 is on the side away from the lifting opening 13, and the lifting opening 13 is arranged upwards or towards the side, but the side of the transparent cover plate 39 of the shooting end 31 faces the passenger. When the camera 3 needs to be used, the controller of the automobile controls the driving piece 225 to operate, the driving piece 225 drives the threaded rod 224 to rotate forward and drives the sliding block 222 to slide towards the side of the lifting opening 13, so as to drive the camera 3 to move towards the outside of the lifting opening 13, and the shooting end 31 passes out of the shell 1. During the process, the bending section 362 of the flexible circuit board 36 is pulled to be straight, light is emitted to the lens 353 through the transparent cover plate 39, the lens 353 receives and focuses the light on the photosensitive chip, the light is converted into an electric signal by the photosensitive chip to form an image in cooperation with the controller. After the shooting is completed, the driving piece 225 drives the threaded rod 224 to reverse and drives the camera 3 of the sliding block 222 to reset. During the resetting process, the flexible circuit board 36 slides on the guide inclined surface 234 to reset, and the camera 3 and the sliding block 222 also return to the initial position.
