[0048] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0049] In order to solve the problems in the prior art, the utility model provides an image acquisition device, which adopts a single-piece mounting bracket to realize the lateral installation of the camera, and hides the cable of the camera inside the mounting bracket, effectively reducing the risk of the cable being damaged.

[0050] like Figures 1a to 3b As shown, an embodiment of the utility model provides an image acquisition device, comprising:

[0051] A camera 10, the camera 10 includes a housing 11, and a lens 12 for shooting via a front surface of the housing 11, the lens 12 having an optical axis extending along a first direction L;

[0052] A mounting bracket 20, wherein the mounting bracket 20 mounts the camera 10 on a carrier, wherein the carrier has a carrier surface 1 extending in a longitudinal direction;

[0053] Wherein, the mounting bracket 20 comprises:

[0054] A first mounting plane portion 21, the first mounting plane portion 21 is fastened to the carrier surface 1 via a first fastener 213;

[0055] A second mounting plane portion 22, the second mounting plane portion 22 is fastened to a side wall of the housing 11 via a second fastener, wherein the side wall extends in a longitudinal direction and is parallel to the first direction L;

[0056] The wire passing portion 23 is fixedly connected between the first mounting plane portion 21 and the second mounting plane portion 22 . The wire passing portion 23 is formed in a cylindrical shape, and two ends thereof form openings in the first mounting plane portion 21 and the second mounting plane portion 22 , respectively.

[0057] In this example, the image acquisition device includes a camera 10 and a mounting bracket 20. The camera 10 is used for image information acquisition, and can be implemented as a common camera for monitoring or image shooting. Optionally, the camera 10 can also have functions such as image information storage. In this example, the mounting bracket 20 adopts an integrated structure, which includes two parallel and spaced mounting plane parts and a wire-passing part connected between the two mounting plane parts.

[0058] The first mounting plane portion 21 is used to connect to the carrier surface 1, the second mounting plane portion 22 is used to connect to the housing 11 of the camera 10, and the rigid wire-passing portion 23 is supported between the first mounting plane portion 21 and the second mounting plane portion 22, forming a gap between the camera 10 and the carrier surface 1. Then, the length of the wire-passing portion 23 determines the gap between the camera 10 and the carrier surface 1.

[0059] The first mounting plane portion 21 and the second mounting plane portion 22 are both formed into a planar structure to achieve a fit and fixation with the carrier surface 1 and the housing 11. However, the shapes of the first mounting plane portion 21 and the second mounting plane portion 22 can be selected according to the actual application scenario. For example, the first mounting plane portion 21 and the second mounting plane portion 22 can be implemented in the same shape, or in different shapes. Optionally, the shapes of the first mounting plane portion 21 and the second mounting plane portion 22 can be selected to be circular, rectangular, square, polygonal, etc. For example, Figure 2a and Figure 2b An example is shown in which the shapes of the first mounting plane portion 21 and the second mounting plane portion 22 are circular. Figure 4 An example is shown in which the shapes of the first mounting plane portion 21 and the second mounting plane portion 22 are square.

[0060] In this embodiment, the camera 10 is installed sideways by the mounting bracket 20. Specifically, the carrier surface 1 is implemented as a plane extending in the longitudinal direction, such as a side wall of a vehicle compartment, etc. It can be understood that the carrier surface 1 does not necessarily extend in an absolutely vertical direction, but generally extends in the longitudinal direction, such as forming a small acute angle with the gravity direction, etc.

[0061] In the housing 11 of the camera 10, its lens 12 is shot through the front surface, and multiple side walls connected to the front surface (including left and right side walls and top and bottom walls) can be used as assembly surfaces connected to the mounting bracket 20, wherein each side wall is parallel to the optical axis direction of the lens 12. When the mounting bracket has an adjustment function that can adjust the installation angle, it can adjust the optical axis direction of the lens 12, thereby improving the adaptability of the image acquisition device of this embodiment.

[0062] In this embodiment, the first mounting plane portion 21 is used to connect to the carrier surface 1, the second mounting plane portion 22 is used to connect to the housing 11 of the camera 10, and the wire-passing portion 23, in addition to providing rigid connection and support, also forms a channel for wire passing therein through a cylindrical shape, wherein the wire-passing portion 23 forms a through opening on both the first mounting plane portion 21 and the second mounting plane portion 22, so that a closed channel is formed between the outer side of the first mounting plane portion 21 and the outer side of the second mounting plane portion 22, and the cable 13 of the camera 10 (which may include a power cable and a signal cable) can be passed from the outer side of the second mounting plane portion 22 to the outer side of the first mounting plane portion 21 through the wire-passing portion 23, and when the first mounting plane portion 21 is fixed to the carrier surface 1, the cable 13 can pass through the carrier surface 1 to extend into the interior of the carrier. When the first mounting plane portion 21 is fixed to the carrier surface 1 and the housing 11 is fixed to the second mounting plane portion 22, the cable is completely shielded by the wire-passing portion and the carrier surface 1, thereby completely avoiding the possibility of the cable being damaged.

[0063] In this embodiment, the mounting bracket adopts a single-piece structure to realize the lateral installation of the camera, and simultaneously realizes the cable shielding function through the supporting structure. It is not only simple in structure and easy to install, but also improves the reliability of the image acquisition device.

[0064] In a preferred example, the mounting bracket may have the function of adjusting the optical axis direction of the lens 12. Specifically, the line-passing portion 23 has a central axis extending along the second direction C, and the second direction C is perpendicular to the first direction L;

[0065] in,

[0066] The first mounting plane portion 21 has a plurality of first arc-shaped holes 211, which are arranged at equal angles around the central axis and are located on the same arc, the arc length of each first arc-shaped hole 211 is greater than the diameter of the first fastener 213, and the first direction L pitches and rotates in response to the position of the first fastener 213 in the first arc-shaped hole; and / or

[0067] The second mounting plane portion 22 has a plurality of second arc holes, which are arranged at equal angles around the central axis, the arc length of each second arc hole is greater than the diameter of the second fastener, and the first direction L pitches and rotates in response to the position of the second fastener in the second arc hole.

[0068] In this embodiment, although the mounting bracket has the function of adjusting the direction of the optical axis, it is not achieved through a complex adjustment bracket, but through the setting of the mounting hole. Specifically, an arc hole can be set on the first mounting plane portion or the second mounting plane portion, and the arc length of the arc hole is greater than the diameter of the corresponding fastener. Based on the fact that the position of the screw hole opened on the fixed object (the carrier surface or the side wall of the shell 11) is fixed, when the position of the fastener in the arc hole changes, the angle of the mounting bracket relative to the fixed object changes, and it rotates around the central axis extending along the second direction C, thereby achieving the purpose of adjusting the optical axis direction of the lens 12. Among them, the function and working principle of the arc hole are the same as those of the common waist-shaped hole. The difference is that the arc hole extends in the arc direction, so the angle direction around the central axis can be adjusted.

[0069] The direction of the second direction C is fixed, while the direction of the first direction L is not fixed, but the first direction L remains perpendicular to the second direction C, that is, orthogonal to the second direction C. When the carrier surface 1 is in the longitudinal direction, the second direction C extends in the direction of the horizontal plane and is perpendicular to the carrier surface 1. When the mounting bracket is rotated as a whole around the central axis by adjusting the position of the fastener in the arc hole, the first direction L pitches and rotates.

[0070] The arc hole can be provided only on the first mounting plane portion 21, or only on the second mounting plane portion 22, or both on the first mounting plane portion 21 and the second mounting plane portion 22, so as to achieve a wider angle range of adjustment. However, in a preferred example, the arc hole is provided only on one of the first mounting plane portion 21 and the second mounting plane portion 22 to meet the angle adjustment requirements.

[0071] exist Figure 2a to Figure 2b In the example shown, the first mounting plane portion 21 has a plurality of first arc-shaped holes 211 and a plurality of first operating holes 212;

[0072] The second mounting plane portion 22 has a plurality of second assembly holes 221, and the second fasteners are adapted to the second assembly holes;

[0073] The first operating holes 212 correspond to the second assembly holes 221 in a one-to-one manner, so that an assembly tool for fastening the second fastener can reach the second installation plane portion 22 from one side of the first installation plane portion 21 through the first operating holes 212 .

[0074] Preferably, each first operating hole 212 is located between a pair of adjacent first arc-shaped holes 211 .

[0075] In this example, the first mounting plane portion 21 is provided with a first arc-shaped hole 211, and the overall angle of the mounting bracket 20 is achieved by adjusting the position of the first fastener in the first arc-shaped hole 211, thereby adjusting the optical axis direction of the lens 12 of the camera 10. The angle adjustment of the mounting bracket in this embodiment is achieved during the installation process of the image acquisition device. Once the image acquisition device is installed, that is, the mounting bracket is fixedly connected to the carrier surface 1 and the housing 11 respectively, the optical axis direction of the lens 12 of the camera 10 is fixed. If adjustment is required, the mounting bracket needs to be re-tightened to achieve it.

[0076] In this embodiment, the first mounting plane portion 21 is provided with a first arc-shaped hole 211, and the second mounting plane portion 22 is provided with a second assembly hole 221 for direct fastening connection without an angle adjustment function. The second assembly hole 221 is adapted to the diameter of the second fastener. Preferably, in order to facilitate the operation of the second fastener, in the example shown in the figure, in addition to the first arc-shaped hole 211, the first mounting plane portion 21 also has a plurality of first operating holes 212, and the first operating holes 212 are coaxially arranged with the second assembly holes 221 on the second mounting plane portion 22, that is, aligned in the second direction C, so that the operation of fastening the second fastener with the second assembly hole 221 and the housing 11 can be achieved via the first operating hole 212. Specifically, an assembly tool (such as a screwdriver) for fastening the second fastener can pass through the first operating hole 212 from one side of the first mounting plane portion 21, so as to touch the second fastener located at the second mounting plane portion 22.

[0077] Similarly, the plurality of first arc-shaped holes 211 are disposed on the same arc with a first diameter, and the distance between the outer edge of the second mounting plane portion 22 and the central axis is smaller than the first diameter.

[0078] In this example, the second mounting plane portion 22 is set to a shape smaller than the first mounting plane portion 21. For example, when the first mounting plane portion 21 and the second mounting plane portion 22 are both circular, the diameter of the second mounting plane portion 22 may be smaller than the first mounting plane portion 21, specifically, it should be smaller than the diameter of the arc where the first arc-shaped hole 211 is located, so that the assembly tool (such as a screwdriver) for the first fastener can directly touch the first fastener located at the first mounting plane portion 21 from one side of the second mounting plane portion 22 and outside the second mounting plane portion 22.

[0079] It can be understood that the above description uses the example that the size of the first mounting plane portion 21 is larger than the size of the second mounting plane portion 22. Similarly, the size of the first mounting plane portion 21 can be smaller than the size of the second mounting plane portion 22, and an operating hole corresponding to the first arc-shaped hole can be set on the second mounting plane portion 22.

[0080] like Figure 1b As shown, the camera 10 includes a safety rope 14 connected to the housing 11 . The safety rope 14 passes through the wire portion 23 to pass through the carrier surface 1 to the inside of the carrier. The end of the safety rope 14 is connected to the carrier.

[0081] The end of the safety rope 14 may have a quick connection structure such as a hook or a buckle to connect and fix with the corresponding connection structure in the carrier to prevent the main body of the camera 10 from falling due to failure of the mounting bracket, and also to save the operator the burden of holding the camera 10 during the installation process.

[0082] In order to reduce the difficulty of installation operation, in addition to the fixing function of the safety rope, such as Figure 2a As shown, the first mounting plane portion 21 includes a positioning portion 24 extending along the second direction C from a side of the first mounting plane portion 21 facing the carrier surface 1;

[0083] The positioning portion 24 is formed into a cylindrical shape around the central axis and penetrates the wire-passing portion 23;

[0084] The carrier surface 1 has a through hole for accommodating the positioning portion 24 , wherein the diameter of the positioning portion 24 matches the diameter of the through hole, and the length of the positioning portion 24 is greater than the thickness of the carrier surface 1 .

[0085] Although the wire-passing portion 23 is not necessarily formed into a cylindrical shape, the positioning portion 24 needs to be formed into a cylindrical shape and be coaxially arranged with the central axis of the wire-passing portion 23 so that when the mounting bracket 20 realizes angle adjustment through the first arc-shaped hole, it can be supported by the positioning portion 24 and rotate around the central axis to realize angle adjustment.

[0086] When fixing the mounting bracket of the present embodiment to the carrier surface 1, the positioning portion 24 can be first inserted into the through hole on the carrier surface 1, and supported by the through hole through the positioning portion 24. Although it cannot provide stable support for the mounting bracket or the mounting bracket 20 equipped with the camera 10, the operator can achieve the effect of stabilizing the position of the mounting bracket 20 by only providing a lateral force that makes the first mounting plane portion 21 fit the carrier surface 1 without bearing the weight of the mounting bracket 20 and the camera 10. Thus, the image acquisition device of the present embodiment can be installed conveniently and quickly.

[0087] Furthermore, if Figure 5 and Figure 7 As shown, the side wall of the housing 11 has a mounting portion 15 matched with the second mounting plane portion 22 , and the mounting portion 15 is recessed into the housing 11 or protrudes from the housing 11 from the side wall.

[0088] The mounting portion 15 is used to be assembled and connected with the second mounting plane portion 22 to provide a flat appearance. Figure 5As shown, the mounting portion 15 can be formed as a groove recessed inside the shell 11, and its shape is consistent with the outer edge of the second mounting plane portion 22, so that the second mounting plane portion 22 can be accommodated in the mounting portion 15 to form a flat surface with the side wall of the shell 11.

[0089] Optionally, the mounting portion 15 may also be Figure 7 As shown, the second installation plane portion 22 protrudes from the surface of the housing 11 , and the second installation plane portion 22 can be formed into a cover-shaped structure in which the installation portion 15 is covered, so as to enclose the installation portion 15 therein.

[0090] In addition to being adapted to be connected with the second mounting plane portion 22 , the mounting portion 15 is also used to provide an external interface.

[0091] For example, the camera 10 includes an electrical interface 16 installed on the mounting portion 15 . The electrical interface 16 mainly includes a power cable portion. That is, the electrical interface 16 can be used for connection with the cable 13 .

[0092] The electrical interface 16 may be adapted to the interface of the mounting portion 15 and may also be implemented in different forms. Figure 5 In the example shown, the mounting portion 15 is formed as a groove recessed in the housing 11, and correspondingly, the electrical interface 16 is embedded in the mounting portion 15, and its interface is exposed to the external surface of the mounting portion 15. Figure 7 In the example shown, the mounting portion 15 protrudes from the surface of the housing 11 . Correspondingly, the electrical interface 16 can be installed on the mounting portion 15 via an external cable 17 in the form of an external cable. The external cable 17 is fixed to the mounting portion 15 via a stress release structure 18 .

[0093] Optionally, the mounting portion 15 may further include a safety rope buckle 19 fixedly connected to the safety rope 14. One end of the safety rope 14 may be fixed to the safety rope buckle 19 by a buckle, a hook or the like, and the other end extends into the carrier surface 1 through the wire portion 23 to be fixed to the carrier.

[0094] In a preferred example, Figure 5 and Figure 6 As shown, the camera 10 has an interface panel 30, which is opened on a surface of the housing 11 other than the front surface and the side wall connected to the mounting bracket, such as other side walls or the rear surface.

[0095] The housing 11 includes a cover plate 31 for covering the interface panel 30 , and the cover plate 31 is fastened to the housing 11 via a third fastener, wherein the third fastener is an anti-theft screw.

[0096] The main function of the anti-theft screw is to prevent theft. It needs to be removed with a special matching tool, thereby reducing the loss caused by theft. The interface panel 30 can be provided with a memory card slot, for example. The use of the anti-theft screw can prevent the risk of stealing the memory card. Optionally, the fastener on the surface of the housing 11 can also be selected in the form of an anti-theft screw to prevent the risk of the camera being stolen.

[0097] In this embodiment, the first mounting plane portion 21 is used to connect to the carrier surface 1, the second mounting plane portion 22 is used to connect to the housing 11 of the camera 10, and the wire-passing portion 23, in addition to providing rigid connection and support, also forms a channel for wire passing therein through a cylindrical shape, wherein the wire-passing portion 23 forms a through opening on both the first mounting plane portion 21 and the second mounting plane portion 22, so that a closed channel is formed between the outer side of the first mounting plane portion 21 and the outer side of the second mounting plane portion 22, and the cable 13 of the camera 10 (which may include a power cable and a signal cable) can be passed from the outer side of the second mounting plane portion 22 to the outer side of the first mounting plane portion 21 through the wire-passing portion 23, and when the first mounting plane portion 21 is fixed to the carrier surface 1, the cable 13 can pass through the carrier surface 1 to extend into the interior of the carrier. When the first mounting plane portion 21 is fixed to the carrier surface 1 and the housing 11 is fixed to the second mounting plane portion 22, the cable is completely shielded by the wire-passing portion and the carrier surface 1, thereby completely avoiding the possibility of the cable being damaged.

[0098] In this embodiment, the mounting bracket adopts a single-piece structure to realize the lateral installation of the camera, and simultaneously realizes the cable shielding function through the supporting structure. It is not only simple in structure and easy to install, but also improves the reliability of the image acquisition device.

[0099] In this embodiment, although the mounting bracket has the function of adjusting the direction of the optical axis, it is not achieved through a complex adjustment bracket, but through the setting of the mounting hole. When the position of the fastener in the arc hole changes, the angle of the mounting bracket relative to the fixed object changes, and it rotates around the central axis extending along the second direction C, thereby achieving the purpose of adjusting the optical axis direction of the lens 12.

[0100] The fasteners on the surface of the housing in this embodiment may be in the form of anti-theft screws to prevent the risk of the camera being stolen and the memory card being stolen.

[0101] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model, and are not intended to limit the scope of protection of the utility model. Any equivalent implementation plans or changes that do not deviate from the technical spirit of the utility model, such as combination, division or repetition of features, should be included in the scope of protection of the utility model.
