[0025] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than the fullest embodiment. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0026] The present invention provides an image acquisition device, comprising a target device and a connecting device, wherein the target device is mounted on the connecting device. The target device may include at least one device including a camera, such as a video camera, a still camera, a mobile phone, a tablet computer, a laptop computer, an in-vehicle device, or a wearable device. The target device can use the camera to acquire images, such as taking photos and recording videos. The present invention does not limit the type of target device.

[0027] Please refer to Figure 1 The connecting device 10 is used to mount the target device on the target rod 20, and the centerline direction of the target rod 20 is parallel to the first direction x. The target rod 20 can include a prism structure such as a quadrangular prism, a hexagonal prism, or an octagonal prism.

[0028] In an embodiment where the target shaft 20 comprises a prismatic structure, the target shaft 20 comprises a first side wall 21 and a second side wall 22 adjacent to each other. The first side wall 21 and the second side wall 22 intersect to form an edge 23, the first side wall 21 being located on one side of the edge 23, and the second side wall 22 being located on the other side of the edge 23. An angle is formed between the first side wall 21 and the second side wall 22, and the angle between the first side wall 21 and the second side wall 22 may be in a range of 0° to 180°. In one example, as Figure 1 As shown, the cross section of the target shaft body 20 perpendicular to the center line is rectangular, and the angle between the first side wall 21 and the second side wall 22 may include 90 degrees. In another example, the cross section of the target shaft body 20 perpendicular to the center line is a regular hexagon, and the angle between the first side wall 21 and the second side wall 22 may include 120 degrees. In yet another example, Figure 2 As shown, the cross section of the target shaft body 20 perpendicular to the center line is a regular octagon, and the angle between the first side wall 21 and the second side wall 22 may also include 135°.

[0029] In some implementations, the image acquisition device may further include a pan-tilt platform, the target device is disposed on the pan-tilt platform, and the pan-tilt platform is mounted on the connecting device 10 to mount the target device on the connecting device 10 .

[0030] Please refer to Figure 3 The connection device 10 in the embodiment of the present application includes a frame 100 and a fixing belt 200 connected to each other. The frame 100 is used to fix the target device, and the fixing belt 200 is wrapped around and installed on the target rod body 20 to install the target device on the target rod body 20.

[0031] The frame 100 includes a mounting portion 110, to which a target device can be secured. In some implementations, the mounting portion 110 is provided with an opening 111, through which the target device or gimbal can be bolted to the mounting portion 110 to be secured thereto. In other implementations, the target device or gimbal can be secured to the mounting portion 110 by welding, gluing, snap-fit ​​connections, or other methods.

[0032] Illustratively, the mounting portion 110 may be in a plate shape. Of course, the mounting portion 110 may also include other shapes such as a rod shape.

[0033] The frame 100 also includes a connecting portion 120, which is disposed on the mounting portion 110 and is configured to connect to the fixing strap 200. In some implementations, the connecting portion 120 has a through hole, through which the fixing strap 200 passes to connect to the connecting portion 120. In other implementations, the fixing strap 200 may be connected to the connecting portion 120 by welding, bonding, snap-fit ​​connection, bolt connection, or the like.

[0034] In an optional embodiment, the connecting portion 120 may be plate-shaped, with a preset angle between the plate-shaped connecting portion 120 and the plate-shaped mounting portion 110. In other optional embodiments, the connecting portion 120 may also include other shapes such as a rod.

[0035] In some implementations, there may be multiple connecting parts 120, such as Figure 3 As shown, the connection portion 120 includes a first connection portion 121 and a second connection portion 122, and the first connection portion 121 and the second connection portion 122 are respectively provided on both sides of the mounting portion 110. Thus, the stability of the connection between the frame 100 and the fixing belt 200 can be improved, and the stability of the connection between the frame 100 and the target rod body 20 can be improved.

[0036] In an optional embodiment, the frame 100 is provided with a contact surface 123, the length of which can be parallel to the first direction x. When the connecting device 10 is installed on the target rod 20, the contact surface 123 is attached to the target rod 20. Based on this configuration, the contact surface 123 can increase the contact area between the frame 100 and the target rod 20, allowing the frame 100 to be more securely installed on the target rod 20. For example, the contact surface 123 can be provided on the connecting portion 120.

[0037] Please continue to refer to Figure 3 The fixing belt 200 of the embodiment of the present application includes a belt body 210, which is connected to the frame 100 and is wound around Figure 1 On the target shaft 20 shown.

[0038] like Figure 1 and Figure 3 As shown, the band 210 may be polygonal, and the number of sides of the band 210 may be equal to the number of edges 23 of the target rod 20. In the embodiment where the target rod 20 comprises a quadrangular prism, the band 210 may comprise a quadrilateral. Figure 2 and Figure 4 As shown, in embodiments where the target shaft 20 comprises an octagonal prism, the band 210 may comprise an octagon.

[0039] The belt body 210 may include an elastic belt, and the material of the belt body 210 may include at least one of stainless steel, spring steel, rubber, plastic, and the like.

[0040] The belt 210 has a first state and a second state. The first state can be an expanded state, and the second state can be a contracted state. During the transition from the first state to the second state, the belt 210 contracts, and the area enclosed by the projection of the belt 210 on a plane perpendicular to the first direction x decreases. During the transition from the second state to the first state, the belt 210 expands, and the area enclosed by the projection of the belt 210 on a plane perpendicular to the first direction x increases.

[0041] In the above embodiment, during the transition of the belt body 210 from the first state to the second state, the two ends of the belt body 210 may approach each other, or the two ends of the belt body 210 may move away from each other.

[0042] Based on the above configuration, the fixing strap 200 further includes a locking device 220 connected to the strap body 210. The locking device 220 is used to adjust the distance between the two ends of the strap body 210 to drive the strap body 210 to switch between the first state and the second state, thereby installing the strap body 210 on the target rod body 20 or removing the strap body 210 from the target rod body 20.

[0043] In one example, when the belt 210 is in the first state, the belt 210 is wrapped around the target rod 20, and the locking device 220 drives the belt 210 to switch from the first state to the second state, causing the belt 210 to contract and press against the target rod 20. At this time, the locking device 220 can drive the belt 210 to continue to contract, thereby increasing the friction between the belt 210 and the target rod 20, so that the belt 210 is more firmly installed on the target rod 20.

[0044] In another example, when the belt body 210 is installed on the target rod body 20, the belt body 210 is in the second state. The locking device 220 drives the belt body 210 to switch from the second state to the first state, so that the belt body 210 expands and then separates from the target rod body 20.

[0045] In an optional embodiment, the locking device 220 includes a lock buckle and a bolt. The lock buckle is provided at one end of the belt body 210, and the lock buckle is provided with an adjustment cavity and an adjustment port extending through the adjustment cavity. The bolt is rotatably provided on the lock buckle, and at least a portion of the bolt is located within the adjustment cavity. The other end of the belt body 210 is provided with a plurality of grooves, which are spaced apart along the length of the belt body 210. The other end of the belt body 210 is passed through the adjustment port, and the grooves on the belt body 210 located within the adjustment cavity engage with the external threads on the bolt. By twisting the bolt, the other end of the belt body 210 can be driven to move within the adjustment cavity to adjust the size of the space enclosed by the belt body 210, so that the belt body 210 can press the pad 300 against the target rod body 20.

[0046] In another alternative embodiment, the locking device 220 may include a bolt and a nut. A first opening is defined at one end of the belt body 210, and multiple second openings are defined at the other end of the belt body 210. The second openings are spaced apart along the length of the belt body 210. A bolt passes through the first opening and any of the second openings and is threadedly engaged with the nut to connect the two ends of the belt body 210. The bolt can pass through different second openings to adjust the distance between the two ends of the belt body 210.

[0047] In the above embodiment, multiple straps 210 and locking devices 220 can be provided. The straps 210 can be spaced apart along the first direction x, with each locking device 220 corresponding to a different strap 210. Based on this arrangement, each strap 210 can be adjusted using a different locking device 220, ensuring a relatively secure connection to the target rod 20. Furthermore, the tightness of each strap 210 can be the same or different, allowing for installation on target rods 20 of varying thicknesses at different locations.

[0048] In one example, if Figure 3 As shown, there are two fixing straps 200. In other examples, there may be three or more fixing straps 200.

[0049] Please refer to Figure 1 and Figure 5 In the embodiment of the present application, the connecting device 10 further includes a pad 300, which has a first surface 310, a second surface 320 and a mating surface 330, wherein the first surface 310 and the second surface 320 are adjacent to each other. Figure 3 The mating surface 330 is used to fit with the fixing belt 200. For example, the mating surface 330 can be used to fit with the belt body 210; the first surface 310 and the second surface 320 are used to fit with the target rod body 20 (such as Figure 1 Thus, the spacer 300 is located between the fixing belt 200 and the target shaft 20.

[0050] In the above embodiment, please combine Figure 1 and Figure 3 The spacer 300 is disposed between the fixing strap 200 and the edge 23 of the target shaft 20. The first surface 310 and the second surface 320 are respectively configured to connect to the first sidewall 21 and the second sidewall 22 of the target shaft 20. In one example, the first surface 310 can be configured to connect to the first sidewall 21, and the second surface 320 can be configured to connect to the second sidewall 22. In another example, the first surface 310 can be configured to connect to the second sidewall 22, and the second surface 320 can be configured to connect to the first sidewall 21.

[0051] Through the above arrangement, the spacer 300 increases the contact area between the connecting device 10 and the target rod body 20 , so that the image acquisition device is more stably installed on the target rod body 20 .

[0052] In some implementations, the mating surface 330 and the belt body 210 are merely in contact. In the second state, the belt body 210 presses the pad 300 against the target shaft 20, causing the mating surface 330 to conform to the belt body 210. The mating surface 330 and the belt body 210 can maintain contact due to friction between the belt body 210 and the pad 300. In other implementations, the mating surface 330 and the belt body 210 can be connected by welding, bonding, snap-fit ​​connection, or other methods. In embodiments where the mating surface 330 and the belt body 210 are non-detachably connected, the pad 300 can prevent the belt body 210 from shifting on the target shaft 20.

[0053] In some implementations, the pad 300 and the target shaft 20 are merely in contact. The belt 210, in the second state, presses the pad 300 against the target shaft 20, causing the first surface 310 to abut against the first sidewall 21, and the second surface 320 to abut against the second sidewall 22. The first surface 310 and the first sidewall 21, as well as the second surface 320 and the second sidewall 22, are both connected by friction between the pad 300 and the target shaft 20. In other implementations, the pad 300 and the target shaft 20 may be connected by welding, bonding, snap-fit ​​connections, or the like.

[0054] In embodiments where the mating surface 330 and the belt body 210 are in contact only and maintained in connection solely by friction, the first surface 310 and the first sidewall 21, and the second surface 320 and the second sidewall 22, may also be maintained in connection solely by friction. For example, the pad 300 is pressed against the target rod body 20 such that the first surface 310 and the first sidewall 21 are in contact, and the second surface 320 and the second sidewall 22 are in contact. The belt body 210, in a first state, is placed over the target rod body 20. The locking device 220 drives the belt body 210 from the first state to the second state, causing the belt body 210 to press the pad 300 against the target rod body 20. This arrangement facilitates replacement of the gasket and facilitates removal of the connecting device 10 from the target rod body 20.

[0055] In an optional embodiment, please combine Figure 1 and Figure 3, the first surface 310 and the second surface 320 can both be parallel to the first direction x. That is, the first surface 310 and the second surface 320 can both be parallel to the centerline of the target shaft 20. Based on the above arrangement, the first surface 310 and the first sidewall 21 are parallel and closely attached to each other, and the second surface 320 and the second sidewall 22 are parallel and closely attached to each other, thereby ensuring that the image capture device is more securely mounted on the target shaft 20.

[0056] In some implementations, the angle between the first surface 310 and the second surface 320 is in the range of 0° to 180°. Figure 3 , the angle between the first surface 310 and the second surface 320 may include 90°. In another example, please refer to Figure 4 , an included angle between the first surface 310 and the second surface 320 may include 135°.

[0057] In the above embodiment, please combine Figure 1 and Figure 3 The angle between the first surface 310 and the second surface 320 can be equal to the angle between the first side wall 21 and the second side wall 22. Based on the above configuration, the first surface 310 and the first side wall 21, as well as the second surface 320 and the second side wall 22, are more tightly fitted, allowing the image capture device to be more securely mounted on the target rod body 20.

[0058] Please combine Figure 5 and Figure 6 In an optional embodiment, the mating surface 330 may include a curved surface. Accordingly, the fixing belt 200 includes a curved portion 211 corresponding to the edge 23. The curved portion 211 may be provided on the belt body 210. The mating surface 330 is in contact with the curved portion 211. Based on the above configuration, please refer to Figure 3 The mating surface 330 and the fixing belt 200 fit more closely, so that the image acquisition device is more stably installed on the target rod body 20.

[0059] In an optional embodiment, the pad 300 may comprise an elastic block. The pad 300 may be made of at least one of rubber, plastic, silicone, foam, and the like. Based on the above structure, during the transition of the belt 210 from the first state to the second state, the belt 210 can compress the pad 300, causing the pad 300 to elastically deform. This allows for a tighter fit between the pad 300 and the target rod 20, and between the pad 300 and the belt 210, thereby more securely mounting the image capture device on the target rod 20. Furthermore, during the compression of the pad 300 by the belt 210, the pad 300 does not damage the belt 210 or the target rod 20.

[0060] In an alternative embodiment, please refer to Figure 3 The mating surface 330 of the pad 300 is provided with a slot, and the belt body 210 is locked in the slot. Through the above arrangement, the stability of the connection between the pad 300 and the belt body 210 is improved.

[0061] In the above embodiment, if Figure 3 As shown, there may be multiple pads 300, each of which may be spaced apart along the extension direction of the belt body 210, and each of which may correspond to a different edge 23 of the target rod body 20. This increases the contact area between the connecting device 10 and the target rod body 20, as well as the contact area between the pads 300 and the belt body 210, allowing the image capture device to be more stably mounted on the target rod body 20.

[0062] In an optional embodiment, a pad 300 is provided between the fixing belt 200 and each edge 23 of the target rod body 20. In one example, the number of pads 300 provided on the fixing belt 200 may be greater than the number of edges 23 of the target rod body 20. In another example, the number of pads 300 provided on the fixing belt 200 may be equal to the number of edges 23 of the target rod body 20. Figure 1 and Figure 3 In the embodiment where the target shaft body 20 comprises a quadrangular prism, four spacers 300 may be provided on one belt body 210 .

[0063] In the embodiment where multiple fixing straps 200 and pads 300 are provided, pads 300 are provided between each fixing strap 200 and each edge 23 of the target rod 20. Based on the above arrangement, the image acquisition device can be mounted on the target rod 20 more stably.
