[0002] In recent years, the action camera market has witnessed remarkable development and changes. From technological advancements to market expansion and then to the diversification of consumer demands, the action camera industry is gradually moving towards maturity and segmentation. Action camera technology has been continuously evolving, including improvements in image quality, more advanced stabilization technology, and more compact and lightweight designs. 4K resolution, waterproof and anti-shake functions have become standard features of many new action cameras.

[0003] In recent years, the automotive industry has started to introduce action cameras. Especially for autonomous driving, an action camera is required and placed at the connection between the front windshield and the roof of the vehicle to enable the action camera to capture images in front of the vehicle. As is well known, the camera module of an action camera has a lower field of view (i.e., the area where the light received by the camera is at the lowest direction), and this lower field of view cannot be blocked by the vehicle body, which determines the installation angle of the camera module. When the existing camera module is installed above the front windshield, since it is necessary for the camera module to capture images in front of the vehicle body, an upper cover is often sleeved outside the camera module. The upper cover is often in a regular shape, and this shape needs to consider the shooting field of view of the camera module, resulting in a relatively large wind resistance problem.

The annular peripheral surface and the top surface form a receiving space, and the receiving space is suitable for receiving a camera module. The annular peripheral surface is provided with mounting holes, and the mounting holes are suitable for receiving the shooting lenses of the camera module.

[0028] By setting different arc segments, the upper cover has a special-shaped shape, and the absolute value of the slope of the first generatrix is less than the absolute value of the slope of the second generatrix, so that the lower viewing angle captured by the camera module in the mounting hole can more easily capture the front image of the vehicle.

[0030] (3) The projections of the geometric centers of the fixing part and the connecting part of the present utility model coincide. The geometric centers of the fixing part and the connecting part coincide with the rotation axis of the rotating lower cover, so that the fixing part, the connecting part and the shooting part all rotate around the rotation center line, enabling the shooting part of the upper cover to rotate during the shooting process.

[0032] (5) The present utility model further includes a decorative shell, which is provided with a through hole.

Specific embodiments

[0048] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0051] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0052] This embodiment provides an upper cover of a pan-tilt camera. As Figure 1 shown in Fig. -11, a specific embodiment of the upper cover of the pan-tilt camera includes: a fixing part 3, a connecting part 2, and a shooting part 1 from bottom to top. The fixing part 3, the connecting part 2, and the shooting part 1 are integrally formed, and the fixing part 3 is adapted to be detachably connected to the rotating lower cover 7.

[0053] As Figure 2 , Figure 3 and Figure 5 shown, the shooting part 1 has an annular peripheral surface 11 and a top surface 101. Among them, the annular peripheral surface 11 and the top surface 101 enclose an accommodation space. As Figure 3As shown in the figure, the annular circumferential surface 11 is composed of a first arc segment 106 and a second arc segment 107 distributed circumferentially. That is, the two ends of the first arc segment 106 and the second arc segment 107 are connected to each other to form a ring, and both the first arc segment 106 and the second arc segment 107 are continuous surfaces (the first arc segment 106 and the second arc segment 107 are continuous and gradually changing surfaces). By setting the continuous surface, on the one hand, the annular circumferential surface 11 is made more beautiful, and on the other hand, the overall air resistance of the photographing part 1 can be reduced. The first arc segment 106 is provided with a mounting hole 102, and the part facing away from the mounting hole 102 is the second arc segment 107. Among them, the first arc segment 106 has a first generatrix 109, and the second arc segment 107 has a second generatrix 110. That is, the first generatrix 109 refers to the moving line forming the surface of the first arc segment 106, and the second generatrix 110 refers to the moving line forming the surface of the second arc segment 107. And the absolute value of the slope of the first generatrix 109 is less than the absolute value of the slope of the second generatrix 110. The slope of the first generatrix 109 refers to the slope of the first generatrix 109 with respect to the axis where the vertical line 108 is located, and the slope of the second generatrix 110 refers to the slope of the second generatrix 110 with respect to the axis where the vertical line 108 is located.

[0054] As Figure 5 shown, the slope of the first generatrix 109 is the maximum slope on the surface where the first arc segment 106 is located, and the slope of the second generatrix 110 is the maximum slope on the surface where the second arc segment 107 is located. And the first generatrix 109 and the second generatrix 110 are arranged oppositely in the circumferential direction of the photographing part 1. In this application, the opposite arrangement means that the angle corresponding to the arc between the first generatrix 109 and the second generatrix 110 is 180 degrees, the slopes of the generatrices of the first arc segment 106 are different at different circumferential positions, and the slopes of the generatrices of the second arc segment 107 are different at different circumferential positions. As Figure 2 、 Figure 3 and Figure 5 shown, the range of the absolute value of the slope of the first generatrix 109 is within to (that is, the range of the first acute angle 111 formed by the first generatrix 109 and the vertical line 108 is 15° - 30°), and the range of the absolute value of the slope of the second generatrix 110 is within 0.7 to 1.19 (that is, the range of the second acute angle 112 formed by the second generatrix 110 and the vertical line 108 is 35° - 50°).

[0055] It should be noted that if the range of the first acute angle 111 formed by the first generatrix 109 and the vertical line 108 is too small (less than 15°), after the upper shell is installed, the installation direction and shooting angle of the camera module 6 are slightly downward. That is, the camera module 6 will capture images in front of the vehicle body. If the first acute angle 111 is too small, it means that the slope of the first generatrix 109 of the first arc surface where the mounting hole 102 is located will be smaller. Since the shooting lens 601 of the camera module 6 and the position of the mounting hole 102 are fixed, this will cause the lower field of view of the camera during shooting to capture the front cover part of the vehicle body, affecting the shooting field of view of the camera. Moreover, if the first acute angle 111 is too small, it will increase the overall wind resistance of the upper shell. If the range of the first acute angle 111 formed by the first generatrix 109 and the vertical line 108 is too large (greater than 30°), since the lower field of view of the camera module 6 will capture images in front of the vehicle, if the first acute angle 111 is too large, it means that the slope of the first generatrix 109 of the first arc surface where the mounting hole 102 is located will be larger. Since the shooting lens 601 of the camera module 6 and the position of the mounting hole 102 are fixed, this will cause the lower field of view of the camera module 6 to capture images far from the vehicle body, affecting the shooting angle of the camera module 6.

[0056] If the range of the second acute angle 112 formed by the second generatrix 110 and the vertical line 108 is too small (less than 35°), it will cause the second arc segment 107 to be similar in shape to the first arc segment 106, increasing the overall volume of the shooting part 1 of the upper cover without changing the shape of the connecting part 2, resulting in an increase in the wind resistance of the shooting part 1 of the upper cover and generating a howling sound. If the range of the second acute angle 112 formed by the second generatrix 110 and the vertical line 108 is too large (greater than 50°), it will cause the generatrix slope of the second arc segment 107 of the shooting part 1 of the upper cover to be too large. On the one hand, it affects the aesthetics of the entire upper cover. On the other hand, without changing the position of the connecting part 2, the space left for the camera module 6 becomes smaller and cannot accommodate the camera module 6.

[0057] By setting different arc segments, the upper cover has an irregular shape, and the absolute value of the slope of the first generatrix 109 is less than the absolute value of the slope of the second generatrix 110, enabling the lower viewing angle captured by the camera module 6 in the mounting hole 102 to more easily capture the front image of the car. That is, the smaller the angle formed by the first acute angle 111 and the vertical line 108, the easier it is for the lower viewing angle of the camera module 6 to capture the front image of the car. The second arc segment 107 away from the mounting hole 102 has a second generatrix 110, and the first acute angle 111 is less than the second acute angle 112, which can better reduce wind resistance and save production materials. That is, the larger the angle between the second generatrix 110 and the vertical line 108, the smaller the wind resistance. In addition, the accommodation space composed of the first arc segment 106 and the second arc segment 107 is also convenient for installing the camera module 6, with enough space to accommodate the camera module 6.

[0058] Such asFigure 2 , Figure 3 and Figure 5 As shown in Figure 2 , Figure 3 , and Figure 5 , there are arc chamfers 201 between the fixing part 3 and the connecting part 2, and between the connecting part 2 and the photographing part 1 respectively. The arc chamfers 201 play a role in beautification and can also prevent harm to users. As Figure 2 , Figure 3 and Figure 5 shown, accommodation spaces are formed in the fixing part 3, the connecting part 2, and the photographing part 1 to accommodate the camera module 6. The photographing part 1 is provided with a mounting hole 102 which is adapted to accommodate the photographing lens 601 of the camera module 6, and a waterproof ring 114 is provided between the photographing lens 601 and the inner side wall of the mounting hole 102 to prevent external water flow and dust from entering the photographing part 1 and avoid the camera module 6 from being eroded by dust and water mist. As Figure 2 , Figure 3 shown, the fixing part 3 and the connecting part 2 are respectively annular. The outer diameter of the fixing part 3 is greater than that of the connecting part 2, and the projections of the geometric centers of the fixing part 3 and the connecting part 2 coincide. The geometric center of the end face at the bottom of the photographing part 1 coincides with the projection of the geometric center of the fixing part 3. It should be noted that, as Figure 1 shown, the geometric center of the top surface 101 is misaligned with the rotation axis of the rotating lower cover 7. As Figure 2 shown, the outer diameter of the connecting part 2 is the same as the outer diameter of the lower end of the photographing part 1, and the annular peripheral surface 11 becomes smaller and smaller upward along the outer diameter of the lower end of the photographing part 1.

[0059] As Figure 9 shown, the camera module 6 includes a circuit board, a sensor, and a photographing lens 601. The photographing lens 601 includes a mounting seat 603. The sensor is arranged on the circuit board. The mounting seat 603 is fixedly connected to the circuit board, and the heat conduction bracket 602 is fixedly connected to the mounting seat 603. As Figure 9 shown, the heat conduction bracket 602 includes a first heat conduction section 6022 and a second heat conduction section 6021 which are connected to each other and form an angle with each other. The first heat conduction section 6022 is connected to the heat dissipation plate. The angle between the first heat conduction section 6022 and the second heat conduction section 6021 is greater than 90° to better conform to the shape characteristics of the photographing part 1, and a convex edge is provided on each side of the first heat conduction section 6022, and a fifth fastening hole 6023 is provided on each convex edge. It should be noted that the first end of the heat conduction bracket 602 in this application is the same as the second heat conduction section 6021, and the second end of the heat conduction bracket 602 is the same as the first heat conduction section 6022 (that is, the second end of the heat conduction bracket 602 is connected to the heat dissipation plate). A large amount of heat is generated during the photographing process of the camera module 6. The heat is transferred from the second heat conduction section 6021 to the first heat conduction section 6022, and then from the first heat conduction section 6022 to the heat dissipation plate, so that the heat dissipation plate exchanges heat with the external air during the vehicle's driving process to reduce the temperature inside the upper cover.

[0060] As Figure 3 shown, on the inner side walls on both sides of the mounting hole 102 of the first arc segment 106, a first fastening hole 104 is respectively provided. A fastener 403 is inserted into each first fastening hole 104, and the first fastening hole 104 is correspondingly arranged with the connection hole 6031 on the mounting seat 603. The fastener 403 fixes the camera module 6 on the inner side wall of the shooting part 1. Specifically, the fastener 403 is a bolt. As Figure 2 、 Figure 3 shown, the top surface 101 of the shooting part 1 is provided with a top surface 101, and further includes a heat dissipation plate. The heat dissipation plate is arranged on the top of the shooting part 1. The outer surface of the heat dissipation plate forms the top surface 101. A third fastening hole 105 is provided below the heat dissipation plate. The fifth fastening hole 6023 of the first heat conduction segment 6022 and the third fastening hole 105 are penetrated by the fastener 403 to fix the first heat conduction segment 6022 of the heat conduction bracket 602 on the heat dissipation plate of the top surface 101, so that the heat of the camera module 6 is transferred to the heat dissipation plate of the top surface 101 through the heat conduction plate. Through the settings of the fifth fastening hole 6023 and the connection hole 6031, the fastener 403 fixes and fastens the camera module 6 from two different angles (at the mounting seat 603 and the first heat conduction segment 6022), and has a better fastening effect compared with single-sided fixation. As Figure 2 shown, a card slot 103 and a fourth fastening hole 113 are provided on the arc segment of the shooting part 1, and a second fastening hole 301 is provided on the fixing part 3. As Figure 12 shown, a notch 302 is provided on the side wall of the fixing part 3 corresponding to the second arc segment 107. The notch 302 forms an installation space allowing an installation tool to enter, facilitating the disassembly and assembly of the inside of the upper cover.

[0061] A pan-tilt camera includes an upper cover, and further includes a decorative shell 4 fixedly connected to the upper cover, and a rotating lower cover 7 detachably connected to the upper cover. As Figure 1 、 Figure 4 、 Figure 6 and Figure 8 shown, the decorative shell 4 is provided with a through hole 401, and the through hole 401 is adapted to allow the shooting part 1 of the upper cover to pass through, so that the heat dissipation plate is in direct contact with the air flow in the air. As Figure 4 、 Figure 8 shown, the decorative shell 4 is further provided with a shooting hole 402, and the shooting hole 402 is correspondingly arranged with the mounting hole 102 of the upper cover. As Figure 8As shown, the decorative shell 4 is provided with a clamping block 404, and the clamping block 404 is adapted to the clamping groove 103. Moreover, the fastener 403 passes through the fourth fastening hole 113 and then penetrates into the decorative shell 4 to fixedly connect the decorative shell 4 with the upper cover. Specifically, the fastener 403 is a bolt. It should be noted that the inner peripheral surface of the decorative shell 4 is adapted to the outer peripheral surface of the shooting part 1 of the upper cover, so that the decorative shell 4 and the shooting part 1 of the upper cover can be arranged in a fitting manner. In addition, the outer peripheral surface of the decorative shell 4 is adapted to the outer peripheral surface of the shooting part 1 of the upper cover, so that the overall air resistance of the outer periphery of the decorative shell 4 is equivalent to the overall air resistance of the shooting part 1 of the upper cover.

[0062] As Figure 2 , Figure 10 shown, a fastener 403 passes through the second fastening hole 301 of the fixing part 3 of the upper cover to be detachably connected with the rotating lower cover 7. Specifically, the fastener 403 is a bolt. To drive the rotating lower cover 7 to move, as Figure 11 shown, it further includes a driving base 8. The rotating lower cover 7 is rotatably connected to the driving base 8 through a rotating shaft. A driving member is arranged in the driving base 8, and the driving member drives the rotating shaft to rotate to drive the rotating lower cover 7 and the upper cover to rotate. Specifically, the driving member is a servo motor. It should be noted that the rotating lower cover 7 has a rotation axis, and the geometric centers of the fixing part 3 and the connecting part 2 coincide with the rotation axis of the rotating lower cover 7. The geometric center of the bottom end face of the shooting part 1 coincides with the rotation axis of the rotating lower cover 7 so that the shooting part 1 can rotate circumferentially. And the Figure 5 vertical line 108 in this application coincides with the rotation axis, and the geometric center of the top surface 101 is misaligned with the rotation axis of the rotating lower cover 7.

[0063] A vehicle includes the above-mentioned pan-tilt camera. As Figure 7 shown, it further includes a cross beam 9 and a decorative panel 5. Among them, the cross beam 9 is located above the front windshield, and a decorative panel 5 is provided above the cross beam 9. The decorative panel 5 is provided with a through hole 501. The driving base 8 of the pan-tilt camera is fixedly arranged on the cross beam 9. The rotating lower cover 7 is located inside the decorative panel 5. The upper cover passes through the through hole 501 of the decorative panel 5 to expose the shooting part 1. The overall size of the shooting part 1 is smaller than the size of the through hole 501 so that the shooting part 1 can easily pass through the through hole 501. The decorative shell 4 is connected to the shooting part 1 to, on the one hand, block external dust and rain from entering the shooting part 1 when the vehicle is running, and can also enhance the overall aesthetics and reduce the overall air resistance. It should be noted that, as Figure 12 shown, there is a gap 10 between the outer peripheral surface of the connecting part 2 and the inner side wall of the through hole 501 to allow the connecting part 2 to rotate reciprocally in the through hole 501. To place the driving base 8, the rotating lower cover 7 and the fixing part 3 of the upper cover of the pan-tilt camera, as Figure 12As shown, a recessed portion 901 is also provided in the middle of the cross beam 9. A space formed between the recessed portion 901 and the decorative plate 5 is used to accommodate the driving base 8, the rotating lower cover 7, and the fixing portion 3 of the upper cover.

[0064] It should be noted that: The pan-tilt camera in this application is not limited to the above position, and can also be installed in other parts of the vehicle (such as the rear end of the vehicle, etc.).

[0065] The upper cover of the pan-tilt camera provided by the utility model has the following advantages:

[0066] (1) Only a part of the upper cover (i.e., the shooting portion 1) is exposed outside. The driving base 8, the rotating lower cover 7, the fixing portion 3 of the upper cover, and the connecting portion 2 of the pan-tilt camera are arranged in the space between the decorative plate 5 and the recessed portion 901 of the cross beam 9, reducing the overall wind resistance of the upper cover of the pan-tilt camera.

[0067] (2) The through hole 401 of the decorative shell 4 is adapted to pass through the heat dissipation plate at the top of the shooting portion 1. The heat dissipation plate is fixedly connected to the heat conduction plate of the camera module 6, so that the heat of the camera module 6 is transferred to the heat dissipation plate through the heat conduction plate. When the vehicle is driving, heat is exchanged between the air and the heat dissipation plate, playing a role in dissipating heat from the camera module 6.

[0068] (3) By setting different arc segments, the first arc segment 106 and the second arc segment 107 are continuous curved surfaces to make the upper cover have a lower wind resistance, giving the upper cover a special shape. And the absolute value of the slope of the first generatrix 109 is less than the absolute value of the slope of the second generatrix 110, enabling the lower viewing angle of the camera module 6 in the mounting hole 102 to more easily capture the image in front of the vehicle. The lower viewing angle of the camera module 6 can more easily capture the image in front of the vehicle. And the second arc segment 107 away from the mounting hole 102 has the second generatrix 110. The fact that the absolute value of the slope of the first generatrix 109 is less than the absolute value of the slope of the second generatrix 110 can better reduce the wind resistance and save production materials. Through the above settings, it can not only ensure that the camera module 6 inside the upper cover can more easily capture the image in front of the vehicle, but also reduce the wind resistance.

[0069] (4) A heat conduction bracket 602 is provided. The heat conduction bracket 602 has a first heat conduction segment 6022 and a second heat conduction segment 6021. A large amount of heat is generated during the shooting process of the camera module 6. The heat is transferred to the first heat conduction segment 6022 through the second heat conduction segment 6021, and then transferred from the first heat conduction segment 6022 to the heat dissipation plate, enabling the heat dissipation plate to exchange heat with the external air during the driving process of the vehicle to reduce the temperature inside the upper cover.

[0070] As an alternative implementation, a third arc segment, a fourth arc segment, etc. are also provided between the first arc segment 106 and the second arc segment 107.

[0071] As an alternative embodiment, the rotation axis and the vertical line 108 may also not coincide.

[0072] As an alternative embodiment, a clamping block 404 is provided on the annular circumferential surface 11, and a clamping groove 103 is provided on the inner side surface of the decorative shell 4, and the clamping block 404 and the clamping groove 103 are adapted to each other.

[0073] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the embodiments. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the embodiments here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
