[0002] Amid the rapid development of the smart car industry, in-vehicle pan-tilt cameras have become a core feature for enhancing vehicle intelligence and entertainment. These devices integrate features such as autofocus, object recognition, and high-definition image capture, meeting the needs of driving recording and security monitoring. They can be mounted on the front roof crossbar behind the windshield (with the camera facing forward), the rear roof crossbar in front of the rear windshield, or the trunk lid (with the camera facing backward). However, mounting a pan-tilt camera on the front or rear roof crossbar requires a large mounting hole for the camera base. The connection between the pan-tilt camera and the crossbar is also susceptible to water leakage into the vehicle body. Furthermore, the relative movement between the moving and fixed components of the pan-tilt camera can lead to water leakage at the joints. Therefore, developing a simple, safe, reliable, and waterproof mounting structure for in-vehicle pan-tilt cameras is a new direction for enhancing the competitiveness of automotive products.

Detailed implementation manners

[0017] The technical solutions of the present invention will be described in detail below with reference to the drawings and embodiments.

[0018] As Figures 1-4 shown, a vehicle-mounted pan-tilt camera mounting structure in this embodiment includes a cross beam and a vehicle-mounted pan-tilt camera 4 disposed in the cross beam. A water flow guiding surface 11 is provided on the outer wall of the cross beam. A transparent window 12 is provided at a position of the water flow guiding surface 11 corresponding to the shooting direction of the camera of the vehicle-mounted pan-tilt camera 4. The water flow guiding surface 11 is a curved surface or an inclined surface gradually extending from a first direction to a second direction, and the second direction is perpendicular to the first direction.

[0019] When the crossbeam is the front roof crossbeam behind the front windshield, the camera shooting direction of the in-vehicle pan-tilt camera 4 faces the front of the vehicle. At this time, the first direction is the direction from the rear to the front of the vehicle, the second direction is the direction from the top to the bottom of the vehicle, and the water flow guiding surface 11 is a curved surface or an inclined surface that gradually extends downward from the rear to the front. When the crossbeam is the rear roof crossbeam behind the rear windshield, the camera shooting direction of the in-vehicle pan-tilt camera 4 faces the rear of the vehicle. At this time, the first direction is the direction from the front to the rear of the vehicle, the second direction is the direction from the top to the bottom of the vehicle, and the water flow guiding surface 11 is a curved surface or an inclined surface that gradually extends downward from the front to the rear.

[0020] In the installation structure of the in-vehicle pan-tilt camera in this embodiment, the in-vehicle pan-tilt camera 4 is arranged inside the crossbeam. The transparent window 12 provides a field of view for the in-vehicle pan-tilt camera 4 so that it can capture external images or videos. The entire in-vehicle pan-tilt camera 4 is inside the crossbeam, and only the sealing of the crossbeam needs to be considered, without considering the sealing between the moving parts and the fixed parts of the in-vehicle pan-tilt camera 4. Therefore, the structure of the in-vehicle pan-tilt camera 4 is simplified. The crossbeam is connected to the rest of the body sheet metal as a whole, and no mounting holes for cooperating with the in-vehicle pan-tilt camera 4 need to be provided on the part of the crossbeam (i.e., the first beam body 1) exposed outside the body. By sealing the transparent window 12, the risk of rainwater entering the crossbeam can be significantly reduced, thereby reducing the sealing cost and the risk of damage to electrical components. At the same time, a water flow guiding surface 11 is provided on the part of the crossbeam (i.e., the first beam body 1) exposed outside the body. Rainwater can smoothly flow from the crossbeam to the rest of the body, further preventing rainwater from entering the crossbeam and affecting the operation of the in-vehicle pan-tilt camera 4. The curved surface or inclined surface of the water flow guiding surface 11 can also reduce wind resistance, overcoming the defect in the traditional technical solution that arranging the in-vehicle pan-tilt camera 4 protruding upward on the roof seriously affects the wind resistance coefficient of the whole vehicle.

[0021] In this embodiment, as Figure 4 shown, the transparent window 12 includes an opening structure 121 and a top cover glass 122. The opening structure 121 is arranged on the water flow guiding surface 11. The opening structure 121 penetrates in the first direction, and the top cover glass 122 is hermetically connected to the opening structure 121.

[0022] The opening structure 121 penetrates in the first direction, that is, the opening direction of the opening structure 121 is the same as the camera shooting direction. When the cross beam is the front roof cross beam behind the front windshield, the camera shooting direction of the vehicle-mounted pan-tilt camera 4 faces the front of the vehicle, the first direction is the direction from the rear to the front of the vehicle, and the opening direction of the opening structure 121 faces the front of the vehicle. When the cross beam is the rear roof cross beam behind the rear windshield, the camera shooting direction of the vehicle-mounted pan-tilt camera 4 faces the rear of the vehicle, the first direction is the direction from the front to the rear of the vehicle, and the opening direction of the opening structure 121 faces the rear of the vehicle. The top cover glass 122 and the opening structure 121 are connected by sealant, which has a simple structure, is convenient for assembly, and can ensure the sealing performance and connection reliability.

[0023] In this embodiment, as Figures 1-4 shown, the vehicle-mounted pan-tilt camera 4 includes a first beam body 1 and a second beam body 2 arranged in sequence along the first direction, and an inner cavity 3 is arranged between the first beam body 1 and the second beam body 2; first connecting flanges 13 are respectively arranged on two different sides of the first beam body 1 in the first direction, second connecting flanges 21 are respectively arranged on two different sides of the second beam body 2 in the first direction, and the two first connecting flanges 13 are respectively abutted against the two second connecting flanges 21.

[0024] The cross section of the second beam body 2 is an inverted "L" shape. The first connecting flanges 13 on the front and rear sides of the first beam body 1 both extend in a direction away from the inner cavity 3, and the second connecting flanges 21 on the front and rear sides of the second beam body 2 both extend in a direction away from the inner cavity 3. By the connection method of abutting the two first connecting flanges 13 against the two second connecting flanges 21 respectively, it can prevent rainwater from entering the cross beam through the connection contact surface between the first connecting flanges 13 and the second connecting flanges 21, and further improve the waterproof ability.

[0025] In this embodiment, as Figures 1-4 shown, a convex platform 14 arched in a direction away from the second beam body 2 is arranged in the middle of the first beam body 1; the water guiding surface 11 is located on the convex platform 14; a support sealing plate 22 is arranged on the second beam body 2, and the vehicle-mounted pan-tilt camera 4 is connected to the support sealing plate 22.

[0026] The upwardly arched boss 14 can increase the volume of the inner cavity 3, thereby ensuring that there is enough installation space for installing the vehicle-mounted pan-tilt camera 4. A relief hole is provided at the bottom of the second beam body 2, and the support sealing plate 22 is connected to the relief hole. The projected area of the support sealing plate 22 and the relief hole in the first direction is larger than the projected area of the vehicle-mounted pan-tilt camera 4 in the first direction, ensuring that the vehicle-mounted pan-tilt camera 4 can enter the crossbeam through the relief hole. Both the first beam body 1 and the second beam body 2 can be sheet metal parts, and the support sealing plate 22 can be a plastic part or a sheet metal part. The connection method between the support sealing plate 22 and the relief hole can be snap connection, gluing or interference fit, etc.

[0027] During installation, first weld the first beam body 1 and the second beam body 2, then install the top cover glass 122, and finally install the vehicle-mounted pan-tilt camera 4 and the support sealing plate 22 from bottom to top through the relief hole to complete the installation. This installation method can prevent the welding of the first beam body 1 and the second beam body 2 from affecting the top cover glass 122, the sealant, the vehicle-mounted pan-tilt camera 4, etc., and is also convenient for performing electrophoresis on the crossbeam alone or for performing body electrophoresis on the crossbeam and the vehicle body together. Moreover, after the vehicle is delivered for use, the after-sales engineer can enter the cockpit to repair or replace the vehicle-mounted pan-tilt camera 4 by removing the support sealing plate 22, without having to disassemble the crossbeam on the roof, which can greatly improve the maintenance convenience.

[0028] In this embodiment, as Figures 5-8 shown, the vehicle-mounted pan-tilt camera 4 includes a camera body 41, a camera mounting bracket 42, a transmission assembly 43, a camera base 44, and a drive assembly 45. The camera body 41 is fixed on the mounting bracket, the transmission assembly 43 is arranged on the camera base 44 in a rotatable manner, the mounting bracket and the drive assembly 45 are respectively connected to the transmission assembly 43, and the drive assembly 45 can drive the mounting bracket to rotate through the transmission assembly 43.

[0029] The vehicle-mounted pan-tilt camera 4 is arranged in the crossbeam, and only the sealing of the crossbeam needs to be considered, without considering the sealing between the moving parts and the fixed parts of the vehicle-mounted pan-tilt camera 4. Therefore, the structure of the vehicle-mounted pan-tilt camera 4 does not need to be provided with a complex sealing structure, and only the basic camera body 41, camera mounting bracket 42, transmission assembly 43, camera base 44, and drive assembly 45 need to be retained.

[0030] In this embodiment, as Figures 5-8As shown, the drive assembly 45 includes an element mounting bracket 451 and a drive element 452. The element mounting bracket 451 is connected to the camera base 44. The drive element 452 is fixedly connected to the element mounting bracket 451. The output shaft of the drive element 452 is connected to the transmission assembly 43. The transmission assembly 43 includes a transmission pedestal 431, a first transmission member 432, and a second transmission member 433. The transmission pedestal 431 is rotatably arranged on the camera base 44. Both the first transmission member 432 and the second transmission member 433 are annular. The inner ring of the first transmission member 432 is arranged outside the transmission pedestal 431. The outer ring of the first transmission member 432 is arranged inside the inner ring of the second transmission member 433. The second transmission member 433 is connected to the camera mounting bracket 42.

[0031] The drive element 452 can be a rotary motor. The element mounting bracket 451 is in an inverted "L" shape and includes a vertical section and a horizontal section. The lower part of the vertical section is fixedly connected to the camera base 44, and the whole vertical section is outside the outer ring of the second transmission member 433. The upper part of the vertical section is connected to the head end of the horizontal section. The tail end of the horizontal section extends into the middle of the camera mounting bracket 42 and is fixedly connected to the drive element 452 by gluing, clamping or other means, so as to hoist the drive element 452 above the transmission pedestal 431. The transmission pedestal 431 is rotatably mounted on the camera base 44. The transmission pedestal 431, the first transmission member 432, and the second transmission member 433 are three structures sleeved from inside to outside in sequence. The output shaft of the drive element 452 drives the transmission pedestal 431 to rotate. The transmission pedestal 431 drives the first transmission member 432 to rotate. The first transmission member 432 drives the second transmission member 433 to rotate. The second transmission member 433 drives the camera mounting bracket 42 to rotate. The camera mounting bracket 42 drives the agricultural camera body 41 to rotate, so as to adjust the shooting angle of the camera of the camera body 41.

[0032] In this embodiment, as Figures 5-8As shown in the figure, the camera mounting bracket 42 includes a first bracket 421 and a second bracket 422. The second bracket 422 has an inverted "U" shape. The two sides of the bottom of the second bracket 422 are respectively connected to different sides of the second transmission member 433. The top of the second bracket 422 is connected to the first bracket 421. The driving element 452 is rotationally engaged with the second bracket 422. Specifically, the second bracket 422 includes two legs and a connecting plate located between the tops of the two legs. The bottoms of the two legs are respectively connected to the left and right sides of the second transmission member 433. The middle part of the connecting plate is rotationally connected to the driving element 452 through a bearing structure. The left and right parts of the connecting plate are respectively fixedly connected to the first bracket 421. The structure between the two legs of the second bracket 422 is hollow, and the middle of the hollow part can provide an installation space for the driving element 452, making the structure of the vehicle-mounted pan-tilt camera 4 more compact.

[0033] In this embodiment, as Figure 5 and Figure 9 shown, one of the technical solutions for the connection of each component of the transmission assembly 43 is as follows: The inner ring of the first transmission member 432 is connected to the transmission base 431 through keyway fit. The outer ring of the first transmission member 432 is connected to the second transmission member 433 through shaft-hole fit. A further refined technical solution is: A plurality of grooves are circumferentially spaced on the inner ring of the first transmission member 432, and a plurality of protruding key bodies 437 are circumferentially spaced on the outer ring of the transmission base 431. The plurality of grooves are connected to the plurality of key bodies 437 in a one-to-one matching manner, so as to realize that the transmission base 431 can drive the first transmission member 432 to rotate. A plurality of jacks 434 are provided on the outer ring of the first transmission member 432, and a plurality of pin holes 435 are provided on the second transmission member 433. The positions of the plurality of jacks 434 and the plurality of pin holes 435 correspond to each other. By respectively passing a plurality of pins 436 through each pin hole 435 and inserting them into each jack 434, the shaft-hole fit connection between the first transmission member 432 and the second transmission member 433 is realized, so as to realize that the first transmission member 432 can drive the second transmission member 433 to rotate, and finally realize driving the camera mounting bracket 42 and the camera body 41 to rotate.

[0034] As Figure 5 and Figure 10As shown, another technical solution for the connection of each component of the transmission assembly 43 is as follows: The inner ring of the first transmission member 432 is connected to the transmission base 431 through keyway fitting; on the opposite sides of the first transmission member 432 and the second transmission member 433, two raceways 439 are provided, and a plurality of rolling elements 438 are circumferentially spaced in both of the two raceways 439 to form a double-row angular contact bearing. A further refined technical solution is: A plurality of grooves are circumferentially spaced on the inner ring of the first transmission member 432, and a plurality of protruding key bodies 437 are circumferentially spaced on the outer ring of the transmission base 431. The plurality of grooves are connected to the plurality of key bodies 437 one by one, so as to enable the transmission base 431 to drive the first transmission member 432 to rotate. A cage for accommodating a plurality of rolling elements 438 is also provided between the first transmission member 432 and the second transmission member 433. The contact angle α of the double-row angular contact bearing is preferably not less than 35°, more preferably not less than 40°. The contact angle refers to the angle between the connecting line of the contact points of the ball and the raceway 439 in the radial plane and the perpendicular line of the bearing axis. There is friction between the first transmission member 432 and the rolling element 438, and there is also friction between the rolling element 438 and the second transmission member 433. Optionally, the friction can be increased by a smaller clearance or increasing the surface roughness of the rolling element 438. And since the load on the second transmission member 433 is the camera body 41 and the camera mounting bracket 42, the load is small and there is no rotational constraint. Therefore, after the transmission base 431 drives the first transmission member 432 to rotate, the friction between the first transmission member 432 and the rolling element 438 and the friction between the rolling element 438 and the second transmission member 433 can drive the second transmission member 433 to rotate, and finally drive the camera mounting bracket 42 and the camera body 41 to rotate.

[0035] A vehicle in this embodiment includes the above vehicle-mounted pan-tilt camera mounting structure. The vehicle can be, but is not limited to, a pure electric vehicle (Pure Electric Vehicle / Battery Electric Vehicle, PEV / BEV), a hybrid electric vehicle (Hybrid Electric Vehicle, HEV), a range-extended electric vehicle (Range Extended Electric Vehicle, REEV), a plug-in hybrid electric vehicle (Plug-in Hybrid Electric Vehicle, PHEV), a new energy vehicle, a fuel vehicle, etc.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
