The first mounting space 11 and the second mounting space 21 are each preferably isosceles trapezoidal in bottom surface, and the depth near the headlamp side is less than the depth away from the headlamp side, i.e. the roof cross beam outer plate 1 and the roof cross beam inner plate 2 are each inclined towards the direction of travel, and the two bases of the isosceles trapezoid are not on the same horizontal plane. On the one hand, this design can meet the installation requirements of the gimbal, and on the other hand, a water guide structure 12 can be formed at the outer edge of the bottom wall of the first mounting space 11, so that rainwater entering through the connecting gap is promptly discharged, prolonging the service life of the gimbal. In addition, a horizontal position lower flow guide groove 13 can also be formed at the position of the roof cross beam outer plate 1 near the headlamp in the width direction of the vehicle body, so that the rainwater in the water guide structure 12 can be promptly discharged along the flow guide groove 13.

By the above arrangement, two blocking surfaces matched with the blocking member are arranged on the limiting sleeve, and the rotation angle of the rotating shaft to the left and right is limited by the two blocking surfaces, which can avoid the problem of excessive rotation of the rotating shaft. Specifically, the blocking member is an arc-shaped protruding strip in the support plate, that is, a protruding strip with an arc. The two ends of the arc-shaped protruding strip respectively form a matching surface matched with the two ends of the annular flange, thereby limiting the rotation angle of the rotating shaft. Specifically, the arc of the arc-shaped protruding strip is smaller than the arc of the gap formed by the annular flange, so that the rotating shaft can rotate and swing left and right.

[0102] As shown in Figure 10 and Figure 11 the upper end of the rotating shaft 3121 is connected with the cover 32 through a fastener, specifically, the upper end of the rotating shaft 3121 has an internal threaded hole for connecting the fastener, and the bolt is connected with the internal threaded hole after being inserted downward from the inside of the cover 32. By the above arrangement, the fastening connection between the upper end of the limiting sleeve and the cover is realized. Further, the upper end of the rotating shaft is also connected with the cover through a positioning member, specifically, the upper end of the rotating shaft has a positioning hole, and the lower end of the cover has a positioning rod which is adapted to be inserted into the positioning hole downward. In the embodiment, the positioning rod and the bolt are matched to realize the fastening and matching of the rotating shaft and the cover.

[0103] The upper end of the limiting sleeve 35 is sealed and matched with the cover 32 through a second sealing structure 37. The upper end of the limiting sleeve 35 has an annular groove 353, and the second sealing structure 37 is arranged in the annular groove 353. The upper side of the second sealing structure 37 is sealed and matched with the cover 32. Through the arrangement of the annular groove, the second sealing structure can be more conveniently and firmly arranged, and the sealing effect and assembly convenience are ensured. In the embodiment, the annular groove is located at the outer circle of the internal thread hole and the positioning hole of the rotating shaft. Through such an arrangement, the sealing between the upper end of the limiting sleeve and the cover is realized, and the sealing of the internal thread hole and the positioning hole on the rotating shaft is also realized, so that water accumulation in the above-mentioned holes is avoided, and the service life of the fastener and the positioning rod is ensured.

[0104] As shown in Figure 12 In the embodiment, the inner wall of the limiting sleeve 35 and the rotating shaft 3121 have a circumferential limiting structure. Specifically, the outer wall of the rotating shaft 3121 protrudes radially outward to form a limiting column 3122, and the inner wall of the limiting sleeve 35 is provided with a vertical recess 354, and the limiting column 3122 is inserted into the vertical recess 354. Through such an arrangement, when the rotating shaft is inserted into the limiting sleeve from top to bottom, the circumferential limiting structure can realize the circumferential fixation of the rotating shaft and the limiting sleeve, that is, synchronous rotation can be realized, and the installation is more convenient. Of course, the above description is not restrictive, and in some alternative embodiments, the limiting column can be arranged on the limiting sleeve, the vertical recess can be arranged on the rotating shaft, or the circumferential limiting structure can also adopt a conventional structure. Further, the upper end of the limiting column has an internal thread hole for connecting the fastener. Through such an arrangement, the limiting column for arranging the internal thread hole can realize the circumferential limiting cooperation with the limiting sleeve and the fixed connection with the cover, so that the structure of the rotating shaft is optimized. A plurality of vertical ribs are arranged on the outer side wall of the rotating shaft, and the vertical ribs are in contact with the inner wall of the limiting sleeve. Through the arrangement of the vertical ribs, the tight fitting force between the rotating shaft and the limiting sleeve after assembly can be increased, and the connection stability between the two parts is ensured. Of course, the above description is not restrictive, and in some alternative embodiments, the vertical ribs can be omitted.

[0105] As shown in Figures 13 to 15As shown, in the embodiment, the lower end of the annular flange is provided with a second groove 355, and a rotating support is arranged in the second groove 355, and the rotating support is fixedly connected with the cover through a fastener. Further, in the embodiment, the rotating support is a waterproof oil seal, which comprises a framework 356 and a sealing ring 357, the framework 356 is arranged above the sealing ring 357, the framework 356 is in sliding fit between the limiting sleeve 35, and the sealing ring 357 is in rotating sealing fit with the rotating shaft 3121. In assembly, the fastener is connected to the cover after penetrating through the framework. Through the above arrangement, the rotating support is arranged at the bottom of the limiting sleeve, which can ensure the stability of the rotating process of the rotating shaft, and the waterproof oil seal is used as the rotating support, which can improve the waterproof performance between the lower end of the rotating shaft and the inside of the cover, thereby further improving the waterproof performance of the cover.

[0106] Further, the cover has a positioning pile for positioning the sealing ring, and the sealing ring has a through hole for inserting the positioning pile. Through the arrangement, the installation stability of the sealing ring can be ensured, and rotation of the sealing ring can be avoided. Further, in the embodiment, the cover also has an annular upwardly protruding convex ring, the convex ring has a plurality of upwardly protruding positioning columns, the bottom surface of the sealing ring has an annular groove for embedding the convex ring, and the annular groove has a insertion hole for inserting the positioning column. Through the arrangement, the sealing ring can be further limited, and the installation stability of the sealing ring can be ensured. The positioning pile has a threaded hole, and the framework is connected to the positioning pile through a fastener after penetrating through the framework after being pressed on the sealing ring. The upper end surface of the sealing ring has an annular groove, and the lower end surface of the framework has an annular convex ring for embedding the annular groove. In this way, the installation stability of the sealing ring can be further ensured.

[0107] As shown, Figure 16 In the embodiment, the transmission mechanism is a speed reduction gear set, the driving mechanism is a horizontally arranged driving motor 3123, and the driving motor is connected with the speed reduction gear set through a worm gear structure. Through the arrangement, the driving motor can relatively accurately drive the rotating shaft to rotate. Of course, the above description is not limiting, and in some alternative embodiments, the driving motor can also be connected with the speed reduction gear set through other structures, such as a bevel gear structure. The speed reduction gear set has a plurality of transmission wheels connected in sequence, and the transmission wheels are connected through meshing. Through the sequential transmission of the transmission wheels, the high-speed rotation of the driving motor can be converted into low-speed driving of the rotating shaft, thereby ensuring the slow and stable rotation of the rotating shaft 3.

[0108] Further, the embodiment also includes a decorative plate assembly 6 covering the roof cross beam, as shown in Figure 5 The decorative plate assembly 6 includes a decorative plate 61 and a decorative plate skeleton 62 arranged in sequence from inside to outside, and the decorative plate 61 and the decorative plate skeleton 62 are connected by a plurality of riveting nuts. The position corresponding to the holder 3 on the decorative plate assembly 6 is provided with a third mounting hole 63 allowing the camera module 4 on the cover 32 to be exposed. The decorative plate 61 and the decorative plate skeleton 62 both extend away from the cockpit to form the third mounting hole 63. This structure effectively reduces the probability of rainwater seeping along the connecting gap by opening the third mounting hole horizontally on the main body surface of the decorative plate. The extension length near the headlamp part is greater than the extension length away from the headlamp part, thereby forming a certain height difference. After the cover is installed, the camera module is slightly inclined upward, expanding the camera module's shooting field of view and maximizing the avoidance of the front cover's obstruction of the shooting field of view.

[0109] To improve the overall aesthetics and waterproof performance of the vehicle body, the exposed part of the cover is provided with an annular decorative cover 7, the inner periphery of the annular decorative cover 7 is adapted to the shape of the outer periphery of the cover 32, and the connection between the top of the cover 32 and the annular decorative cover 7 is provided with a mounting groove, and the corresponding position of the annular decorative cover 7 is provided with a protrusion embedded in the mounting groove, as shown in Figure 2 The cover 32 includes a detachable upper cover 321 and a lower cover 322, and the connection between the upper cover 321 and the lower cover 322 is provided with a third sealing structure. The outer periphery of the lower cover is provided with an annular groove, and an O-ring as the third sealing structure is arranged in the annular groove. The upper cover is arranged on the lower cover and is fixedly connected to the lower cover through the threaded holes and bolts arranged at intervals on the outer periphery, and at the same time the bolts exert a certain extrusion force on the O-ring to make it fill the annular groove.

[0110] As shown in Figure 17As shown, the upper cover includes a shooting portion 3211, a connecting portion 3212 and a fixing portion 3213 arranged in sequence from top to bottom, and the shooting portion, the connecting portion and the fixing portion are integrally formed. The shooting portion has an annular peripheral surface 3214 and a top surface 3215, and the annular peripheral surface and the top surface enclose a containing space suitable for containing the camera module. The annular peripheral surface includes a first arc-shaped segment 3216 and a second arc-shaped segment 3217 distributed in the circumferential direction, and the first arc-shaped segment is provided with a third mounting hole. The camera module is mounted on the third mounting hole of the upper cover through a mounting seat on the inner circumferential wall of the annular peripheral surface. The first arc-shaped segment and the second arc-shaped segment are both continuous curved surfaces, the first arc-shaped segment where the third mounting hole is located has a first generatrix 3218, and the second arc-shaped segment has a second generatrix 3219. That is, the first generatrix refers to the motion line forming the curved surface of the first arc-shaped segment, and the second generatrix refers to the motion line forming the curved surface of the second arc-shaped segment. The absolute value of the slope of the first generatrix is smaller than the absolute value of the slope of the second generatrix. The slope of the first generatrix refers to the slope of the first generatrix about the axis where the vertical line 36 is located, that is, the maximum slope on the curved surface where the first arc-shaped segment is located. The slope of the second generatrix refers to the slope of the second generatrix about the axis where the vertical line is located, that is, the maximum slope on the curved surface where the second arc-shaped segment is located. The first generatrix and the second generatrix are oppositely arranged along the circumferential direction of the shooting portion. The slope of the generatrix at different circumferential positions of the first arc-shaped segment is different, and the slope of the generatrix at different circumferential positions of the second arc-shaped segment is different. Specifically, as shown in the figure, Figure 18 The absolute value of the slope of the first generatrix is in the range of 0.7 to 1.19 (that is, the second acute angle formed by the second generatrix and the vertical line is in the range of 35°-50°). That is, the first generatrix and the vertical line form a first acute angle in the range of 15°-30°, and the absolute value of the slope of the second generatrix is in the range of 0.7 to 1.19 (that is, the second acute angle formed by the second generatrix and the vertical line is in the range of 35°-50°).

[0111] It should be noted that if the first acute angle 111 formed by the first generatrix and the vertical line is too small (less than 15°), after the upper cover is mounted, the mounting direction of the camera module and the shooting angle are slightly downward, that is, the camera module will shoot the image in front of the vehicle body. If the first acute angle is too small, it means that the slope of the first generatrix of the first arc-shaped surface where the third mounting hole is located will be smaller, and the position of the shooting lens of the camera module and the third mounting hole is fixed, which will cause the downward view of the camera to shoot the front cover part of the vehicle body when shooting, affecting the shooting view of the camera. And the first acute angle is too small, which will increase the overall wind resistance of the upper cover. If the first acute angle formed by the first generatrix and the vertical line is too large (greater than 30°), since the downward view of the camera module will shoot the image in front of the vehicle, if the first acute angle is too large, it means that the slope of the first generatrix of the first arc-shaped surface where the third mounting hole is located will be larger, and the position of the shooting lens of the camera module and the third mounting hole is fixed, which will cause the downward view of the camera module to shoot the image away from the vehicle body, affecting the shooting angle of the camera module.

[0112] If the second acute angle range formed by the second generatrix and the vertical line is too small (less than 35°), the second arc-shaped segment will be similar in shape to the first arc-shaped segment, which will increase the overall volume of the shooting part of the upper cover and increase the wind resistance of the shooting part of the upper cover, resulting in whistling. If the second acute angle range formed by the second generatrix and the vertical line is too large (greater than 50°), the slope of the second generatrix of the second arc-shaped segment of the shooting part of the upper cover will be too large, which will affect the aesthetics of the entire upper cover and reduce the space available for the camera module.

[0113] By setting different arc-shaped segments, the upper cover has a special shape, and the absolute value of the slope of the first generatrix is smaller than the absolute value of the slope of the second generatrix, so that the downward viewing angle of the camera module in the third mounting hole can more easily capture the image in front of the vehicle, that is, the smaller the first acute angle with the vertical line, the easier it is for the camera module to capture the image in front of the vehicle. The second arc-shaped segment away from the third mounting hole has a second generatrix, and the first acute angle is smaller than the second acute angle, which can better reduce the wind resistance and save production materials, that is, the larger the angle between the second generatrix and the vertical line, the smaller the wind resistance. In addition, the accommodating space composed of the first arc-shaped segment and the second arc-shaped segment also facilitates the installation of the camera module, and there is enough space to accommodate the camera module.

[0114] The connecting part and the fixing part are both annular, and the outer diameter of the fixing part is larger than that of the connecting part. The geometric center of the fixing part and the geometric center of the connecting part are coincident in projection, and the geometric center of the fixing part and the geometric center of the connecting part are coincident with the rotation axis of the lower cover. The geometric center of the top surface is misaligned with the rotation axis of the lower cover. The outer diameter of the connecting part is the same as that of the lower end of the shooting part 1, and the annular peripheral surface becomes smaller as it goes up along the outer diameter of the lower end of the shooting part. The annular peripheral surface is provided with a clamping groove, and the inner side surface of the annular decorative cover is provided with a clamping block, and the clamping block and the clamping groove are adapted; or, the annular peripheral surface is provided with a clamping block, and the inner side surface of the annular decorative cover is provided with a clamping groove, and the clamping block and the clamping groove are adapted, to realize the installation and fixation of the annular decorative cover and the upper cover.

[0115] As shown in Figure 19 , the camera module includes a circuit board 41, a sensor, and a camera 42, the camera includes a mounting seat, the sensor is arranged on the circuit board, and the mounting seat is fixedly connected with the circuit board. And a fourth sealing structure is arranged at the contact position of the camera and the third mounting hole, the fourth sealing structure is an O-ring arranged around the camera, which can prevent external water flow and dust from entering the camera module, and avoid the erosion of the camera module by dust and water mist.

[0116] To ensure the heat dissipation effect of the holder, as shown in Figure 20 and Figure 21As shown, the camera module further comprises a mounting bracket 8 and a heat sink 323, the heat sink is arranged on the top of the shooting part, the outer surface of the heat sink forms the top surface, the lower surface is provided with a groove, the top part of the mounting bracket is accommodated in the groove and connected with the heat sink. In this embodiment, after the heat sink on the top of the upper cover is connected with the mounting bracket, the heat on the mounting bracket can be better transmitted to the external atmosphere.

[0117] Specifically, the mounting bracket comprises a first heat-conducting segment 81, a second heat-conducting segment 82, a first positioning part 83 and a second positioning part 84. The first heat-conducting segment is adapted to contact and exchange heat with the circuit board of the camera. The second heat-conducting segment is connected with the first heat-conducting segment and is adapted to contact and exchange heat with the top surface. The first positioning part is arranged on the first heat-conducting segment and is adapted to be positioned with the camera mount. The second positioning part is arranged on the second heat-conducting segment and is adapted to be positioned with the upper cover. The positioning direction of the first positioning part and the positioning direction of the second positioning part have a preset angle. The first heat-conducting segment can transmit the heat on the circuit board of the camera to the second heat-conducting segment, and then the second heat-conducting segment transmits the heat to the top surface. When the camera follows the vehicle in the moving process, the external wind blows to the top surface, thereby achieving a good heat dissipation effect. In addition to the side of the camera mount contacting the upper cover being positioned on the upper cover, the camera mount is also positioned on the upper cover through the second positioning part connected thereto, and the first positioning part and the second positioning part are not coplanar, thereby multi-directionally positioning the camera mount and strengthening the stability of the camera positioning. The angle between the first heat-conducting segment and the second heat-conducting segment is in the range of 142.5° to 170°, so that the camera lens has an elevation angle of 10° to 37.5°, thereby ensuring that the camera module has a shooting depression angle in the range of 10° to 20°.

[0118] In some embodiments, the first positioning part comprises at least one first positioning lug plate integrally connected with the first heat-conducting segment, and at least one first positioning hole 85 is formed in the first positioning lug plate. The second positioning part comprises at least one second positioning lug plate integrally connected with the second heat-conducting segment, and at least one second positioning hole 86 is formed in the second positioning lug plate. As a specific embodiment, two first positioning lug plates are arranged, and the two first positioning lug plates are respectively located on the left and right sides of the first heat-conducting segment, so that the positioning between the first heat-conducting segment and the camera mount is more stable. Two second positioning lug plates are arranged, and the two second positioning lug plates are respectively located on the left and right sides of the second heat-conducting segment, so that the positioning between the second heat-conducting segment and the upper cover is more stable.

[0119] The second positioning part is connected with the second heat conduction section through the transition section, the plane of the second positioning part is arranged in a staggered manner with the plane of the second heat conduction section, and the plane of the second positioning part is lower than the plane of the second heat conduction section, and is suitable for providing a containing space for a positioning stud arranged on the upper cover. In the embodiment, the upper cover is positioned by being connected with the second heat conduction section through a screw, and the upper cover is provided with a positioning stud which is threadedly connected with the screw, and the positioning stud is often protruded from the upper cover. Therefore, the containing space formed between the second positioning part and the second heat conduction section can accommodate the positioning stud, so that the second heat conduction section can still contact and exchange heat with the upper cover after being connected with the upper cover.

[0120] Specifically, the first heat conduction section and the second heat conduction section are both red copper heat conduction members. In the embodiment, the red copper has good heat conductivity, and can timely conduct heat away from the position of the circuit board of the camera, so as to avoid heat accumulation inside the cover body. The first heat conduction section and the second heat conduction section are both provided in a plate shape, and are integrally connected and have an included angle therebetween, so that the first positioning part arranged on the first heat conduction section and the second positioning part arranged on the second heat conduction section are not coplanar.

[0121] Because the existing resin PCB cannot be directly connected with the heat dissipation plate, the existing resin PCB has large thermal resistance and poor heat dissipation effect when dissipating heat. In order to solve the technical problem, in some embodiments, the circuit board of the camera is provided as a flexible circuit board, the back surface of the flexible circuit board is fixed with a camera heat conduction rear cover 43, and the other surface of the camera heat conduction rear cover is in contact with the mounting bracket. More specifically, the camera heat conduction rear cover is clamped between the mounting bracket and the flexible circuit board. In the embodiment, the existing resin PCB is replaced by the flexible circuit board, the flexible circuit board can bond and fix the camera heat conduction rear cover, the camera heat conduction rear cover can better transmit heat on the flexible circuit board to the mounting bracket, thereby reducing the thermal resistance and improving the heat dissipation effect; and the camera heat conduction rear cover also plays a role of protecting the circuit board of the camera.

[0122] In some embodiments, a camera main control circuit board 44 is further arranged on the lower cover, the camera main control circuit board is a SOC PCB, and the camera main control circuit board and the circuit board of the camera are connected through a wire harness. Part of the flexible circuit board is bent and arranged inside the upper cover, and then a wire harness is arranged at the end of the flexible circuit board, so as to be directly plugged and connected with the circuit board of the camera.

[0123] As Figure 22As shown, the top wall of the lower cover is provided with at least one raised rib plate 324, which is in contact with the heat-emitting position of the camera main control circuit board. The arrangement of the raised rib plate is determined based on the heat-emitting position of the camera main control circuit board, and when the heat-emitting position of the camera main control circuit board is multiple, one raised rib plate can be arranged at each heat-emitting position. In the embodiment, the raised rib plate can timely transfer the heat on the camera main control circuit board to the lower cover, and then dissipate the heat through the lower cover. The raised rib plate in the embodiment plays the effect of accelerating heat dissipation. In addition, the outer side wall of the lower cover is provided with at least one fin 325. In the embodiment, the fin can accelerate the heat dissipation speed of the lower cover, so that the heat in the cover body is quickly dissipated.

[0124] In some embodiments, the top wall of the upper cover is provided with at least one positioning stud 326 at the bottom end, which corresponds to the second positioning hole of the second positioning part, and the positioning stud and the second positioning part are positioned by a screw. The side wall of the upper cover is provided with a third mounting hole suitable for the camera to pass through, and the camera mounting seat is fixed to the inside of the side wall of the upper cover. More specifically, as shown in Figure 23 As shown, the camera is provided with a first positioning block 421, and the first positioning block is provided with a third positioning hole 422 and a fourth positioning hole 423.

[0125] The side wall of the fixing part away from the third mounting hole is provided with a gap, and the gap forms a mounting space allowing the installation tool to enter, facilitating the installation of the holder and other structures by the staff.

[0126] The camera module is suitable for outdoor shooting, and the shooting depression angle of the camera module is in the range of 10° to 20°, and the shooting pitch angle of the camera module is in the range of 60° to 75°, as shown in Figure 24 The shooting depression angle of the camera module is the included angle between the lower edge of the camera module shooting visual angle and the horizontal line, and the depression angle is generally lower than the horizontal line. The shooting pitch angle is the difference between the shooting elevation angle and the shooting depression angle, and the shooting elevation angle is the included angle between the upper edge of the camera module shooting visual angle and the horizontal line, and the depression angle is generally higher than the horizontal line.

[0127] As shown in Figure 24 and Figure 25As shown, taking the vehicle body as an example, the height of the vehicle body can be in the range of 1.905 m, that is, the height of the camera module 1 is in the range of 1.905 m, the height of the engine cover can be in the range of 1.549 m, and the horizontal distance between the camera module 1 and the front end of the vehicle body can be in the range of 2.044 m, so that the shooting depression angle of the camera module 1 passes through the vehicle body, for example, the engine cover part. The shooting elevation angle of the camera module is in the range of 60° to 75°, so that the sky part in the video and picture is more beautiful.

It can be understood that the shooting angle of the camera module 1 is tangent to the surface of the vehicle body. The camera module is no longer blocked by the vehicle head, and the video and pictures obtained no longer have the vehicle head part.
