[0003] For example, Chinese Patent Document CN115665548A discloses a camera automatic focusing device including a horizontal movement mechanism, a horizontal rotation mechanism, a vertical movement mechanism, and a vertical rotation mechanism; the horizontal movement mechanism drives the horizontal rotation mechanism, the vertical rotation mechanism, and the vertical movement mechanism to move in the horizontal direction; the vertical movement mechanism drives the horizontal rotation mechanism and the vertical rotation mechanism to move in the vertical direction, so as to adjust the offset angle and the pitch angle by making the camera to be focused move in the horizontal direction and rotate in the horizontal circumferential direction at the same time; the vertical movement mechanism drives the horizontal rotation mechanism and the vertical rotation mechanism to move in the vertical direction.

[0004] However, the design of the above camera automatic focusing device has the following problems:

[0005] For the above camera automatic focusing device, although it can drive the camera to perform rapid rotational focusing through the horizontal rotation mechanism, due to the height difference of the camera caused by the focal length difference of the camera, when focusing on cameras with different focal lengths, it is necessary to repeatedly adjust the vertical movement mechanism. Not only is it difficult to accurately adapt the adjusted height to the camera height, but also the frequent adjustment is very cumbersome to operate. Summary of the Utility Model

[0033] To better understand the technical solutions and beneficial effects of this disclosure, the following further details this disclosure with specific embodiments:

[0034] As Figure 1 shown, a multi-focal length camera focusing device 10 includes an image detection mechanism 100, a clamping and focusing mechanism 200, a camera transmission mechanism 300, a height measurement mechanism 400, and a height adjustment mechanism 500; the image detection mechanism 100 is used to acquire and detect the image of the camera; the clamping and focusing mechanism 200 is used to focus the camera; the camera transmission mechanism 300 is used to transmit the camera; the image detection mechanism 100 and the clamping and focusing mechanism 200 are sequentially arranged above the camera transmission mechanism 300; the height measurement mechanism 400 is arranged between the image detection mechanism 100 and the clamping and focusing mechanism 200 and is arranged opposite to the camera transmission mechanism 300, and the height measurement mechanism 400 is used to detect the height of the camera; the height adjustment mechanism 500 includes a guiding bracket 510 and a lifting driver 520, and both the lifting driver 520 and the clamping and focusing mechanism 200 are arranged on the guiding bracket 510; the lifting driver 520 is fixedly connected to the guiding bracket 510 and is electrically connected to the height measurement mechanism 400; the clamping and focusing mechanism 200 is slidably connected to the guiding bracket 510 and is connected to the telescopic rod of the lifting driver 520, so that the clamping and focusing mechanism 200 approaches or moves away from the camera transmission mechanism 300.

[0035] It can be understood that by arranging the altimeter mechanism 400 between the image detection mechanism 100 and the clamping and focusing mechanism 200, since the image detection mechanism 100, the altimeter mechanism 400, and the clamping and focusing mechanism 200 are sequentially arranged on the transfer path of the camera transfer mechanism 300, the camera on the camera transfer mechanism 300 will detect the height through the altimeter mechanism 400 after detecting the image through the image detection mechanism 100. Since the lifting driver 520 is electrically connected to the altimeter mechanism 400, the clamping and focusing mechanism 200 is slidably connected to the guiding bracket 510, and the clamping and focusing mechanism 200 is connected to the telescopic rod of the lifting driver 520, the lifting driver 520 can automatically adjust the height of the clamping and focusing mechanism 200 according to the detection data of the altimeter mechanism 400. When the camera on the camera transfer mechanism 300 passes through the clamping and focusing mechanism 200, the clamping and focusing mechanism 200 can accurately adapt to the height of the camera for rapid adjustment.

[0036] It can be understood that compared with the prior art camera automatic focusing device, the above multi-focal length camera focusing device 10 detects the height of the camera through the altimeter mechanism 400, so that the lifting driver 520 can automatically adjust according to the height of the camera. This not only enables the clamping and focusing mechanism 200 to accurately adapt to cameras with different focal lengths, but also reduces the inconvenience in use caused by frequent adjustments.

[0037] Combined with Figure 1 and Figure 2 As shown, in one embodiment, the guiding bracket 510 is provided with a guiding slide rail 5110 and a lifting frame 5120; the lifting frame 5120 is slidably connected to the guiding slide rail 5110 and fixedly connected to the telescopic rod of the lifting driver 520; the clamping and focusing mechanism 200 is installed on the lifting frame 5120. It can be understood that since the lifting frame 5120 is slidably connected to the guiding slide rail 5110, the telescopic rod of the lifting driver 520 is fixedly connected to the lifting frame 5120, and the clamping and focusing mechanism 200 is installed on the lifting frame 5120, the lifting frame 5120 can be smoothly pushed to lift and slide by the lifting driver 520, and further the clamping and focusing mechanism 200 can synchronously approach or move away from the camera transfer mechanism 300.

[0038] Combined with Figure 1 and Figure 2As shown, in one embodiment, the clamping and focusing mechanism 200 includes a connecting frame 210, a turntable 220, and a clamping frame 230. The connecting frame 210 is fixedly connected to the lifting frame 5120, and the turntable 220 is rotatably arranged on the connecting frame 210. The clamping frame 230 is installed at the central position of the turntable 220 and is arranged opposite to the camera transmission mechanism 300. It can be understood that by installing the clamping frame 230 at the central position of the turntable 220, since the turntable 220 is rotatably arranged on the connecting frame 210 and the clamping frame 230 is arranged opposite to the camera transmission mechanism 300, when the camera is transported by the camera transmission mechanism 300 to below the clamping and focusing mechanism 200, the camera can be clamped by the clamping frame 230, and by rotating the turntable 220, the clamping frame 230 can clamp the camera and quickly rotate for focusing.

[0039] Combined with Figure 2 As shown, in one embodiment, the clamping and focusing mechanism 200 further includes a teleconverter 240. The teleconverter 240 is arranged on the connecting frame 210 and is opposite to the position of the clamping frame 230. It can be understood that by arranging the teleconverter 240 opposite to the clamping frame 230, when the clamping frame 230 clamps the camera, the camera will face the teleconverter 240, and the teleconverter 240 can lengthen the field of view of the camera, so that the camera can simulate the situation of long-distance shooting and is more convenient for the camera to focus.

[0040] Combined with Figure 1 As shown, in one embodiment, the height measuring mechanism 400 includes a laser altimeter 410 and a mounting frame 420. The mounting frame 420 is arranged above the camera transmission mechanism 300 and is provided with a detection port 4210. The laser altimeter 410 is embedded at the detection port 4210 and is arranged opposite to the camera transmission mechanism 300. It can be understood that by embedding the laser altimeter 410 at the detection port 4210, the laser altimeter 410 can be firmly installed on the mounting frame 420, and since the laser altimeter 410 is opposite to the position of the camera transmission mechanism 300, when the camera on the camera transmission mechanism 300 passes through the height measuring mechanism 400, the laser altimeter 410 can measure the height of the camera by emitting laser towards the camera.

[0041] Combined with Figure 1As shown, in one embodiment, the image detection mechanism 100 includes a mounting bracket 110, a detection camera 120, and an annular light source 130; the mounting bracket 110 is disposed above the camera transmission mechanism 300, the detection camera 120 and the annular light source 130 are disposed on the mounting bracket 110, the annular light source 130 is disposed between the detection camera 120 and the camera transmission mechanism 300, and the lens of the detection camera 120 is disposed opposite to the camera transmission mechanism 300 through the inner ring of the annular light source 130. It can be understood that by disposing the annular light source 130 between the detection camera 120 and the camera transmission mechanism 300, since the lens of the detection camera 120 is disposed opposite to the camera transmission mechanism 300 through the inner ring of the annular light source 130, when the camera transmission mechanism 300 transports the camera to below the image detection mechanism 100, the lens of the detection camera 120 can take a picture of the camera through the inner ring of the annular light source 130, and the annular light source 130 supplements light to the camera, so that the image of the camera taken is clearer, and ultimately it is convenient for subsequent detection processes.

[0042] Combined with Figure 1 As shown, in one embodiment, the multi-focal length camera focusing device 10 further includes a camera programming mechanism 600, and the camera programming mechanism 600 is disposed at the rear end of the clamping and focusing mechanism 200; the camera programming mechanism 600 is located above the camera transmission mechanism 300, and the camera programming mechanism 600 is used to irradiate and program the camera. It can be understood that by disposing the camera programming mechanism 600 at the rear end of the clamping and focusing mechanism 200, after the clamping and focusing mechanism 200 focuses on the camera, the camera can be transported by the camera transmission mechanism 300 to below the camera programming mechanism 600, and the camera programming mechanism 600 irradiates the camera on the camera carrier, and the camera programs according to the received light source conditions.

[0043] Combined with Figure 1 As shown, in one embodiment, the camera programming mechanism 600 includes a mounting frame 610 and a programming light board 620, the mounting frame 610 is disposed above the camera transmission mechanism 300, and the programming light board 620 is mounted on the mounting frame 610. It can be understood that by mounting the programming light board 620 on the mounting frame 610, the programming light board 620 can be tightly connected to the mounting frame 610. When the camera is transported by the camera transmission mechanism 300 to below the camera programming mechanism 600, the programming light board 620 can irradiate the camera, and the camera can program according to the received light source conditions.

[0044] Combined Figure 1 As shown, in one embodiment, the camera transmission mechanism 300 includes a push-pull driver 310, a linear transmission seat 320, and a support slide plate 330. The linear transmission seat 320 extends below the image detection mechanism 100 and the clamping and focusing mechanism 200. The support slide plate 330 is slidably disposed on the linear transmission seat 320 and is connected to the push rod of the push-pull driver 310. It can be understood that by slidably disposing the support slide plate 330 on the linear transmission seat 320, since the support slide plate 330 is connected to the push rod of the push-pull driver 310, when the camera is placed on the support slide plate 330, the push-pull driver 310 can push the support slide plate 330 to slide on the linear transmission seat 320. Also, because the linear transmission seat 320 extends below the image detection mechanism 100 and the clamping and focusing mechanism 200, the camera can sequentially pass through the detection process of the image detection mechanism 100 and the focusing process of the clamping and focusing mechanism 200 along the linear transmission seat 320.

[0045] In one embodiment, the electrical connection can be in various forms such as wired connection, wireless connection, etc. It can be understood that the wired connection can be wire connection or circuit board connection, etc., and the wireless connection can use Bluetooth connection or WIFI (Wireless Fidelity) connection, etc. The specific connection method is not limited, and those skilled in the art can also adjust according to needs.

[0046] It should be particularly noted that the method by which the lifting driver 520 automatically adjusts the height of the clamping and focusing mechanism 200 according to the detection data of the height measuring mechanism 400 is a prior art and is not within the protection scope of the present disclosure. The present disclosure only protects the positional relationship and connection relationship between the various components of the multi-focal length camera focusing device 10.

[0047] Combined Figure 1 As shown, the present disclosure also provides a multi-focal length camera focusing device, including the multi-focal length camera focusing device 10 of any of the above embodiments. It can be understood that by applying the multi-focal length camera focusing device 10 of the present disclosure in the multi-focal length camera focusing device, the height of the camera is detected by the height measuring mechanism 400, so that the lifting driver 520 can automatically adjust according to the height of the camera. This not only enables the clamping and focusing mechanism 200 to accurately adapt to cameras with different focal lengths, but also reduces the inconvenience in use caused by frequent adjustments.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1) By arranging the altimetry mechanism 400 between the image detection mechanism 100 and the clamping and focusing mechanism 200, since the image detection mechanism 100, the altimetry mechanism 400, and the clamping and focusing mechanism 200 are sequentially arranged on the transfer path of the camera transmission mechanism 300, the camera on the camera transmission mechanism 300 will detect the height through the altimetry mechanism 400 after detecting the image through the image detection mechanism 100. Since the lifting driver 520 is electrically connected to the altimetry mechanism 400, the clamping and focusing mechanism 200 is slidably connected to the guiding bracket 510, and the clamping and focusing mechanism 200 is connected to the telescopic rod of the lifting driver 520, the lifting driver 520 can automatically adjust the height of the clamping and focusing mechanism 200 according to the detection data of the altimetry mechanism 400. When the camera on the camera transmission mechanism 300 passes through the clamping and focusing mechanism 200, the clamping and focusing mechanism 200 can accurately adapt to the height of the camera for rapid adjustment.

[0050] 2) Compared with the existing camera automatic focusing device, for the above multi-focal length camera focusing device 10, the height of the camera is detected by the altimetry mechanism 400, so that the lifting driver 520 can automatically adjust according to the height of the camera. This not only enables the clamping and focusing mechanism 200 to accurately adapt to cameras with different focal lengths, but also reduces the inconvenience in use caused by frequent adjustments.

[0051] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
