Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle accessories, and in particular relates to a dual-camera mounting bracket. Background Art

[0002] Due to the long body length and high driving position of commercial vehicles, there are a lot of blind spots in front and sides of the vehicle body that cannot be seen through the rearview mirror. Therefore, in order to improve driving safety, it is very necessary to add blind spot cameras in the front and left and right sides of commercial vehicles.

[0003] At present, the blind spot camera installation plan is usually to install a group of cameras on the left and right rearview mirror frames respectively. Each group of cameras includes two cameras for detecting different viewing areas, one of which is used to detect the forward blind spot or the rear blind spot, and the other is used to focus on detecting the lateral blind spot. Based on the installation requirements of dual cameras, the current solution is a patent with application number 202320178947.6, named Blind Spot Monitoring Camera Bracket. The specific plan is to use a single bracket to install two blind spot cameras at the same time. However, the disadvantage of this solution is that both cameras need to be adjusted at multiple angles such as front and rear roll, yaw, and pitch. This makes the installation and debugging process very cumbersome, time-consuming and labor-intensive, affecting work efficiency, and the bracket solution needs to be further improved.

[0014] Exemplarily, the fixing seat includes:

[0015] The hoop seat is used to abut against the rearview mirror frame, and has hoop grooves at both ends for inserting a clamp suitable for tightening the rearview mirror frame.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0023] Please also read Figure 1 and Figure 2 The dual-camera mounting bracket provided by the utility model is now described. The dual-camera mounting bracket includes a fixing seat 10, a roll frame 20, two pitch frames 30, and two camera brackets 40; wherein the fixing seat 10 is used to be fixedly connected to the rearview mirror frame, and the fixing seat 10 has a mounting base 100; the roll frame 20 is rotatably connected to the mounting base 100, and the rotation axis is perpendicular to the mounting base 100, and the roll frame 20 has a vertical mounting surface 200; the two pitch frames 30 are rotatably connected to the vertical mounting surface 200 based on the same rotation axis, and are respectively located on both sides of the vertical mounting surface 200, the rotation axis of the pitch frame 30 is perpendicular to the rotation axis of the roll frame 20, and the two pitch frames 30 both have a horizontal mounting surface 300; the two camera brackets 40 are rotatably connected to the two horizontal mounting surfaces 300, and the rotation axis of the camera brackets 40 is perpendicular to the horizontal mounting surface 300, and the two camera brackets 40 are respectively suitable for horizontally rotating and connecting a blind spot camera 50.

[0024] It should be explained that, since the rearview mirror frames of different vehicles have different shapes, it is difficult to ensure that the fixing seat 10 can form a vertical mounting base 100 after being connected to the rearview mirror frame. Therefore, the mounting base 100 in this embodiment can be understood as being close to parallel to the vertical plane rather than absolutely parallel. It is based on this situation that the roll frame 20 and the mounting base 100 are rotated to adjust the front and rear tilt angles to ensure that a vertical mounting surface 200 is formed on the roll frame 20. On this basis, it is only necessary to adjust the pitch angle of the two pitch frames 30 as a whole to obtain two horizontal mounting surfaces 300 located in the same horizontal plane. The two blind spot cameras 50 are respectively connected to the two horizontal mounting surfaces 300 based on their respective camera brackets 40. They only need to independently adjust their respective yaw angles and pitch angles, thereby simplifying the angle adjustment steps of the blind spot camera 50. Therefore, the installation efficiency of the blind spot camera 50 is naturally improved.

[0025] Compared with the prior art, the dual-camera mounting bracket provided in the present embodiment can level the horizontal mounting surface 300 by horizontally rotating the roll frame 20 and synchronously swinging the two pitch frames 30 up and down, and then directly adjust the yaw angles of the two blind spot cameras 50 by adjusting the two cameras based on the horizontal mounting surface 300. Finally, the pitch angles of the two blind spot cameras 50 can be adjusted separately based on the two camera brackets 40. Compared with the method of adjusting the two blind spot cameras 50 completely independently, it can simplify the installation and debugging process of the blind spot cameras 50 and improve the installation efficiency of the blind spot cameras 50.

[0026] In some embodiments, see Figure 2 Two first arc holes 101 are concentrically arranged on the mounting base surface 100 , and the centers of the two first arc holes 101 coincide with the rotation axis of the roll frame 20 . Two first fasteners 21 are passed through the roll frame 20 , and the two first fasteners 21 are respectively connected to the two first arc holes 101 .

[0027] Here, the first fastener 21 can be a combination of a bolt and a nut, with two bolts passing through the two first circular arc holes 101 respectively and forming a circumferential sliding fit with the first circular arc holes 101, so that the roll frame 20 can be relatively rotated relative to the mounting base surface 100 with the common center of the two first circular arc holes 101 as the rotation axis, thereby adjusting the roll angle of the two blind spot cameras 50 in the front and rear directions as a whole. When the vertical mounting surface 200 on the roll frame 20 reaches the actual vertical state, it is adjusted in place, and at this time, the nut can be tightened. The structure is simple and stable, and the front and rear roll angle adjustment process is convenient and quick.

[0028] As a specific implementation of the above-mentioned pitch frame 30, please refer to Figure 1 and Figure 2The two tilt frames 30 are provided with a folded edge 31 on the side close to each other, and the two folded edges 31 are respectively fitted with the two sides of the vertical mounting surface 200, and the two folded edges 31 and the vertical mounting surface 200 are connected by a second fastener 32 that is horizontally penetrated, and the second fastener 32 forms a common rotation axis of the two tilt frames 30.

[0029] Here, it can be understood that the two folded edges 31 and the vertical mounting surface 200 clamped between the two folded edges 31 form a three-layer laminated plate structure, and the second fastener 32 can be a combination of bolts and nuts. The bolts pass through the above three layers of plates and are screwed and fixed with nuts. When adjusting, it is only necessary to loosen the nuts to make the two pitch frames 30 synchronously rotate around the bolts relative to the vertical mounting surface 200 to achieve synchronous pitch adjustment, until the horizontal mounting surfaces 300 of the two pitch frames 30 both reach the actual horizontal state, and tighten the nuts after adjusting to the right position. Of course, if the method of screwing and fixing based on a simple second fastener 32 is used, the two pitch frames 30 can also be adjusted independently (when the shaft hole 42 between the second fastener 32 and the pitch frame 30 is rotatably matched), thereby improving the flexibility of pitch angle adjustment.

[0030] It should be noted that see Figure 2 A second arc hole 201 is provided on the vertical mounting surface 200 , the center of the second arc hole 201 coincides with the axis of the second fastener 32 , and a third fastener 311 is commonly penetrated on the two folded edges 31 , and the third fastener 311 passes through the second arc hole 201 .

[0031] The two folded edges 31 can be connected together by using the third fastener 311, so as to ensure that the two pitch frames 30 can swing up and down synchronously around the second fastener 32 when the pitch angle is adjusted. After adjustment, the third fastener 311 (specifically a combination of bolts and nuts) and the second fastener 32 can be tightened. The adjustment method is simple and labor-saving, and at the same time, it can also improve the connection stability between the two pitch frames 30 and the vertical mounting surface 200 after adjustment.

[0032] For some possible implementations, see Figure 2 Two third circular arc holes 41 are concentrically arranged on the two camera brackets 40, and the centers of the two third circular arc holes 41 coincide with the rotation axis of the camera bracket 40. Two fourth fasteners 301 are respectively penetrated on the two horizontal mounting surfaces 300, and each fourth fastener 301 is respectively connected to one of the third circular arc holes 41.

[0033] Here, the fourth fastener 301 can be a combination of a bolt and a nut. The bolt passes through the third arc hole 41 and is threadedly engaged with the nut. After loosening the nut, the camera bracket 40 can be rotated relative to the horizontal mounting surface 300, thereby adjusting the lateral swing angle of the blind spot camera 50. At this time, the rotation axis of the blind spot camera 50 relative to the horizontal mounting surface 300 is the common center of the two third arc holes 41. The adjustment method is simple and labor-saving. The use of two fourth fasteners 301 for threaded fixation can improve the connection stability between the camera bracket 40 and the horizontal mounting surface 300.

[0034] Alternatively, see Figure 2 In this embodiment, one or both of the horizontal mounting surfaces 300 are provided with at least one group of through holes 302 suitable for inserting the fourth fastener 301, and each group of through holes 302 is spaced along the rotation circumference of the camera bracket 40. Considering that the arc angle of the third circular arc hole 41 constrains the yaw angle adjustment range of the camera bracket 40, it is inevitable that it cannot exceed 180 degrees, and the connection between the two third circular arc holes 41 determines the structural strength, so the arc of the third circular arc hole 41 should not be too large. However, in order to ensure that the blind spot camera 50 has sufficient yaw angle adjustment capability, especially for the blind spot camera 50 in the forward or rearward viewing area, two or more groups of through holes 302 are provided on the horizontal mounting surface 300. By replacing the through holes 302 through which the fourth fastener 301 passes, the yaw angle adjustment range can be further increased on the basis of the circumferential adjustment range of the third circular arc hole 41, thereby meeting the installation requirements of different vehicle models.

[0035] Specifically, combined Figure 1 and Figure 2 It is understood that in this embodiment, the camera bracket 40 is an inverted U-shape that is arranged across the blind spot camera 50, and the top wall of the camera bracket 40 is in contact with the horizontal mounting surface 300, and the third arc hole 41 is arranged on the top wall of the camera bracket 40. The U-shaped bracket can form a space suitable for the blind spot camera 50 to extend into, and can connect the two sides of the blind spot camera 50 respectively, thereby improving the connection stability of the blind spot camera 50. On this basis, the top wall between the cameras is fixedly attached to the horizontal mounting surface 300, which can prevent the camera bracket 40 from shaking relative to the horizontal mounting surface 300, thereby improving the installation stability of the blind spot camera 50.

[0036] It should be noted that see Figure 2 , shaft holes 42 are provided on both side walls of the mouth of the camera bracket 40, and the two shaft holes 42 are concentric and respectively suitable for rotationally connecting the connecting shafts 51 on both sides of the blind spot camera 50. The connecting shafts 51 on both sides of the blind spot camera 50 are respectively inserted into the two shaft holes 42 to form a rotational fit, and the connection structure is simple and the pitch angle adjustment is convenient.

[0037] On the basis of the above, in order to ensure the connection stability between the blind spot camera 50 and the camera bracket 40 after the pitch angle is adjusted to the right position, as shown in FIG. Figure 2 As shown, at least one fourth arc hole 43 concentric with the shaft hole 42 is provided on both side walls of the mouth of the camera bracket 40, and a fifth fastener 44 is inserted in each of the fourth arc holes 43, and the fifth fastener 44 is screwed and fixed to the blind spot camera 50. The screwing and fixing of the fifth fastener 44 to the side wall of the blind spot camera 50 can prevent the blind spot camera 50 from rotating freely relative to the camera bracket 40, thereby improving the connection stability of the blind spot camera 50; after loosening the fifth fastener 44, the fifth fastener 44 can slide in the fourth arc hole 43 to release the pitch adjustment freedom of the blind spot camera 50, with a simple structure, high stability, and convenient and labor-saving adjustment.

[0038] As a specific structure of the fixing seat 10, see Figure 1 and Figure 2 The fixing seat 10 includes a hoop seat 11 and a connecting seat 12; wherein the hoop seat 11 is used to abut against the rearview mirror frame, and has hoop grooves 111 at both ends for embedding a clamp suitable for tightening the rearview mirror frame, and the portion of the hoop seat 11 located between the two hoop grooves 111 forms a first connecting surface 112, and two sixth fasteners 113 are spaced apart on the first connecting surface 112; the connecting seat 12 has a mounting base surface 100, and a second connecting surface 121 that is in contact with the first connecting surface 112, the second connecting surface 121 is perpendicular to the mounting base surface 100, and two fifth arc holes 122 are concentrically arranged on the second connecting surface 121, and the two fifth arc holes 122 are respectively suitable for two sixth fasteners 113 to pass through.

[0039] Two clamps are embedded in the clamp grooves 111 at both ends of the clamp seat 11 and then clamped on the rearview mirror frame, so that the clamp seat 11 is fixed on the rearview mirror frame. The clamp can be a common flexible metal throat clamp, which can not only be adaptively deformed with the shape of the clamp position, but also can adjust the diameter of the clamp in the clamped state as needed. It is flexible and convenient to use. Whether it is a metal rod type rearview mirror frame (thinner and usually round) or a plastic shell type rearview mirror frame (thicker and usually close to a rectangle), it can be stably and reliably connected and fixed; on this basis, the sixth fastener 113 penetrated on the first connecting surface 112 and the fifth arc hole 122 on the second connecting surface 121 form a circumferential sliding fit. When the sixth fastener 113 (specifically, it can be a combination of bolts and nuts) is loosened, the connecting seat 12 can be rotated relative to the clamp seat 11, which is equivalent to adjusting the yaw angle of the two blind spot cameras 50 as a whole, so that the yaw angles of the two blind spot cameras 50 can be adjusted synchronously and individually, thereby improving the adjustment flexibility of the blind spot cameras 50.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
