DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0038] The following describes the embodiments of the present application in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0039] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0040] The present application embodiment provides a camera mounting assembly with adjustable angle, such as Figure 1 and Figure 2 As shown, the camera mounting assembly of the embodiment of the present application includes a mounting base 100, a mounting bracket 200, and a driving assembly 400;

[0041] The mounting bracket 200 is rotatably disposed on the mounting base 100 , and the camera 300 can be fixedly disposed on the mounting bracket 200 ;

[0042] The driving assembly 400 is disposed on the mounting bracket 200 and the mounting base 100 , and controls the mounting bracket 200 to rotate relative to the mounting base 100 through a multi-stage gear transmission to adjust the mounting angle of the camera 300 .

[0043] Since the driving component of the present application adjusts the installation angle of the camera through a multi-stage gear transmission, and the multi-stage gear transmission makes the transmission more stable, the entire component will not have slight deformation or rebound after the angle adjustment is completed, and the installation angle can be maintained without rebound after adjusting to the specified installation angle; in addition, if the number of teeth of each gear is calculated in advance, the accuracy of the camera installation angle can be controlled. For example, for every rotation of the driving worm, the camera can be deflected by 0.5°, and the installation angle can be accurately adjusted through a simple rotation operation.

[0044] In some embodiments of the present application, the drive assembly 400 includes a gear set consisting of an internal gear 410 , a worm gear 420 , and a worm 430 ;

[0045] The inner gear 410 is fixedly disposed on the mounting bracket 200 , the worm gear 420 is rotatably disposed on the mounting bracket 200 , and the inner gear 410 is meshedly connected with the first roller gear 421 of the worm gear 420 ;

[0046] The worm 430 is disposed on the mounting base 100 , and a driving thread of the worm 430 is meshedly connected with the second roller gear 422 of the worm wheel 420 .

[0047] Since the worm gear 420 is a transmission member, during the installation process of the worm gear 420, in order to avoid interference between the rotating shaft of the worm gear 420 and the side of the mounting bracket 200, a worm gear avoidance portion 220 is provided at a corresponding position on the side of the mounting bracket 200, such as Figure 2 As shown, the worm gear avoidance portion 220 may be an avoidance hole or an avoidance structure of other shapes.

[0048] When the worm 430 is driven to rotate, the worm wheel 420 drives the inner gear 410 to rotate. Since the inner gear 410 is fixed to the mounting bracket 200 and the camera 300 is fixed to the mounting bracket 200 by screws, the camera 300 can deflect relative to the mounting base 100.

[0049] In this embodiment, the worm 430 is a power source, which can eventually drive the camera 300 to rotate around the connecting shaft 500 through the gear connection.

[0050] In this embodiment, the driving stages of the internal gear 410, the worm wheel 420 and the worm 430 are gradually increased, and the gear set is a reduction gear set.

[0051] When the worm 430 is pressed Figure 3When rotating in the direction shown, the worm gear 420 is driven to rotate, and then the inner gear 410 is driven to rotate, achieving a predetermined driving effect. This embodiment involves a gear set transmission composed of three gears. It can be seen that the driving level is gradually increased, so this gear is designed as a reduction gear set. By calculating the number of teeth of each gear, the accuracy of the camera deflection angle can be effectively controlled to achieve controllable installation angle accuracy. For example, for each rotation of the worm 430, the camera 300 can deflect 0.5°, achieving a relatively high rotation accuracy.

[0052] In practical applications, the internal gear can be designed according to the adjustment range of the camera installation angle. Figure 2 The internal gear shown in the figure is in the shape of an arc, and the arc length of the internal gear can be designed as required.

[0053] It should be noted that the embodiment of the present application shows a gear set consisting of three gears. In other embodiments of the present application, a gear set consisting of more than three gears can also be designed, and those skilled in the art can reasonably select the number of gears.

[0054] In some embodiments of the present application, the worm 430 further includes a rotating shaft 432 and an operating port 433;

[0055] The driving thread of the worm 430 is fixed or integrally formed on one end of the rotating shaft 432 , and the other end of the rotating shaft 432 is exposed to the operating port 433 .

[0056] like Figure 4 As shown, the operation port 433 may be in a trumpet shape, and the other end of the rotating shaft 432 may be configured as an inner hexagon structure, so as to facilitate the use of a conventional inner hexagon wrench for rotation operation.

[0057] In an embodiment of the present application, the mounting base 100 is a U-shaped base, the mounting bracket 200 is an I-shaped bracket, the mounting bracket 200 is inserted into the mounting base 100, and the two are assembled through a connecting shaft 500, so that the mounting bracket 200 can rotate around the mounting base 100 with the connecting shaft 500 as the axis; and the camera 300 can be engaged in the mounting groove of the mounting bracket 200 and fixed by screws to ensure the stability of the connection between the camera 300 and the mounting bracket 200.

[0058] A worm mounting portion 110 is disposed on one side of the U-shaped base, and the worm 430 is rotatably disposed on the worm mounting portion 110 .

[0059] In some implementation schemes of this embodiment, the worm 430 includes a worm stop cover 431, and the worm mounting portion 110 has a groove body for avoiding the driving thread. The rod body of the worm 430 is fixedly set on the worm mounting portion 110 through the worm stop cover 431, and the driving thread of the worm 430 is avoided through the groove body.

[0060] Combination Figure 1 and Figure 2 For example, the rod body of the worm 430 is fixed by two worm stop covers 431, for example, the rod body of the worm 430 is fixed to the outside of the groove body by screws. When the worm 430 is fixedly installed on the mounting base 100, the driving thread of the worm 430 can be avoided by the groove body so as not to affect the rotation of the driving thread.

[0061] It should be noted that in the embodiment of the present application, a gear set is provided on one side of the mounting base 100 and the mounting bracket 200, and the gear set can be used to control the mounting bracket 200 to deflect relative to the mounting base 100. In other embodiments, a gear set can be provided on each of the two side surfaces, and the mounting angle of the camera 300 can be controlled by the gear sets on the two side surfaces.

[0062] like Figure 5 As shown, in some embodiments of the present application, the rotatable connection between the mounting bracket 200 and the mounting base 100 is achieved through a connecting shaft 500 .

[0063] Specifically, the angle-adjustable camera mounting assembly further includes two connecting shafts 500 whose axes are co-linear;

[0064] Each side surface of the mounting base 100 is respectively provided with a first shaft mounting through hole 120 , and the mounting bracket 200 has a second shaft mounting through hole 210 matched with each first shaft mounting through hole 120 ;

[0065] The mounting bracket 200 is rotatably disposed on the mounting base 100 through the connecting shaft 500 , the first shaft mounting through hole 120 , and the second shaft mounting through hole 210 .

[0066] In some implementations of this embodiment, Figure 6 and Figure 7 As shown, the connecting shaft 500 includes a slot 510 and a special-shaped fin 520, and the slot 510 and the special-shaped fin 520 are respectively located at two ends of the connecting shaft 500; the slot 510 prevents the mounting bracket 200 and the mounting base 100 from having relative axial displacement;

[0067] The special-shaped fins 520 prevent the rotating shaft 500 and the mounting bracket 200 from rotating relative to each other.

[0068] In this way, after the axial end of the connecting shaft 500 passes through the first shaft mounting through hole 120 and the second shaft mounting through hole 210 in sequence, a retaining spring is installed in the slot 510, and the slot 510 and the retaining spring stabilize the connection between the mounting bracket 200 and the mounting base 100, preventing the mounting bracket 200 and the mounting base 100 from generating relative axial displacement, so that the two can only rotate relative to each other; and through the limiting effect of the special-shaped fin 520, the rotating shaft 500 and the mounting bracket 200 are prevented from rotating together.

[0069] In addition, in practical applications, the worm mounting portion 110 and the rotating shaft 500 may be arranged on opposite sides of the side surface to improve the connection stability between the mounting bracket 200 and the mounting base 100 .
