Description

Technical Field

[0001] The utility model relates to the technical field of video monitoring equipment, in particular to a pan / tilt camera transmission component and a pan / tilt camera. Background Art

[0002] The pan / tilt head is a supporting device for installing and fixing the camera. It has the function of carrying the camera for horizontal and vertical rotation. Installing the camera on the pan / tilt head can enable the camera to shoot from multiple angles.

[0003] A camera with a pan / tilt is called a pan / tilt camera. Currently, pan / tilt cameras are generally divided into fixed pan / tilt cameras and electric pan / tilt cameras according to their adjustment methods. Fixed pan / tilt cameras require manual adjustment of the camera's horizontal and pitch angles, while electric pan / tilt cameras can adjust their azimuths by executing electric motors.

[0004] The existing electric omnidirectional pan / tilt heads generally have two motors inside, which are responsible for the up / down and left / right rotation of the pan / tilt heads respectively. The applicant has found that such a structure generally requires a large number of gears and bevel gears to be matched for transmission, and there is a complex transmission component structure, which leads to a complex method for controlling the up / down and left / right rotation, and a large overall size of the pan / tilt head camera.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0038] Figure 1 Schematic diagram of the explosion structure of this embodiment. Figure 2 yes Figure 1 The main structure diagram is as follows: Figure 1 and Figure 2 As shown, this embodiment provides a pan-tilt camera transmission assembly, including a transmission compartment 1, a transmission mechanism 2, a first power assembly 3 and a second power assembly 4.

[0039] The transmission mechanism 2 is disposed in the transmission compartment 1 , and includes a first transmission structure 21 and a second transmission structure 22 that are symmetrically arranged, and a third transmission structure 23 that is vertically connected to the first transmission structure 21 and the second transmission structure 22 .

[0040] Specifically, Figure 3 2 is a left-view structural diagram of this embodiment, Figure 4 yes Figure 3 AA cross-sectional structure diagram, as shown in Figure 3 and Figure 4 As shown, in this embodiment, the first transmission structure 21 and the second transmission structure 22 both include an annular body 210, the inner ring of the annular body 210 is provided with transmission teeth 211, and the outer ring of the annular body 210 is provided with bevel teeth 212. The third transmission structure 23 includes a bevel gear for meshing with the bevel teeth 212.

[0041] like Figure 1 and Figure 2 As shown, the first power assembly 3 is arranged on one side of the transmission compartment 1, including a first accommodating compartment 30 and a first power device 31 arranged inside the first accommodating compartment 30, and the first power device 31 is transmission-connected to the first transmission structure 21; the second power assembly 4 is arranged on the other side of the transmission compartment 1, including a second accommodating compartment 40 and a second power device 41 arranged inside the second accommodating compartment 40, and the second power device 41 is transmission-connected to the second transmission structure 22.

[0042] In this embodiment, the outer diameters of the first accommodating compartment 30 and the second accommodating compartment 40 are the same as the outer diameter of the transmission compartment 1. A transmission mechanism 2 is arranged in the transmission compartment 1, a first power device 31 is arranged in the first accommodating compartment 30, and a second power device 41 is arranged in the second accommodating compartment 40. Under the premise of not affecting normal use, the transmission mechanism 2, the power device, etc. are all placed in a regular accommodating structure with the same outer diameter, which greatly reduces the overall size of the pan-tilt camera transmission assembly, and the transmission structure is less and the coordination between the transmission components is simple, which reduces the cost and improves the pan-tilt load.

[0043] In this embodiment, the first power device 31 and the second power device 41 both include motors, and a gear 311 is disposed at the output end of the motor, and the gear 311 meshes with the transmission teeth 211. Specifically, in this embodiment, the number of teeth of the gear 311 is less than that of the transmission teeth 211.

[0044] As an optional embodiment, the PTZ camera transmission assembly further includes a base 5, and the third transmission structure 23 is fixedly connected to the base 5. Specifically, in this embodiment, a bracket mounting portion 50 is provided on the base 5, which is used to mount the PTZ camera bracket 6 through a connector, so as to facilitate the installation and use of the PTZ camera.

[0045] As an optional embodiment, a camera mounting structure 70 is provided on both the first accommodating chamber 30 and the second accommodating chamber 40, and the length of the camera mounting structure 70 is arranged along the circumference of the first accommodating chamber 30 and the second accommodating chamber 40, and the width of the camera mounting structure 70 is not greater than the width of the first accommodating chamber 30 and the second accommodating chamber 40.

[0046] With such arrangement, after the camera 7 is installed, the camera mounting structure 70 can be placed at the bottom of the camera 7 without being exposed and without taking up too much space, thereby making the installation size of the overall structure smaller and making the pan-tilt camera more applicable.

[0047] Figure 5 Schematic diagram of the structure of the pan / tilt camera of this embodiment. Figure 5 As shown, this embodiment also provides a pan-tilt camera, including the above-mentioned pan-tilt camera transmission assembly and camera 7, and camera 7 is installed on the pan-tilt camera transmission assembly.

[0048] The working principle of this embodiment is:

[0049] When the two motors rotate at the same speed and in opposite directions, the base 5 and the transmission compartment 1 remain relatively still, and the first accommodating compartment 30 and the second accommodating compartment 40 rotate vertically relative to the transmission compartment 1, thereby realizing vertical rotation of the camera 7.

[0050] When the two motors rotate at the same speed and in the same direction, the first accommodating compartment 30 , the second accommodating compartment 40 and the transmission compartment 1 remain relatively still, and the transmission compartment 1 rotates horizontally relative to the base 5 , thereby realizing horizontal rotation of the camera 7 .

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
