Description

Technical Field

[0001] The present disclosure relates to the technical field of automobile camera focusing, and in particular to a rotary power distribution focusing mechanism and a camera focusing device. Background Art

[0002] With the widespread use of new energy vehicles, cameras are often installed on them to improve their safety and intelligence. To improve the quality of cameras before they leave the factory, most manufacturers will perform focus adjustment on the cameras in advance, and some manufacturers have further developed this technology.

[0003] For example, Chinese patent document CN215734600U discloses a camera automatic test focusing mechanism, which includes a first drive module, an automatic focusing module arranged on the first drive module, and an automatic centering module and a lens clamping module arranged on the automatic focusing module; the automatic centering module is used to adjust the clamping position of the lens clamping module to be concentric with the lens of the camera module before focusing; the automatic focusing module is used to drive the lens clamping module to drive the lens to rotate to achieve focusing.

[0004] However, the design of the above-mentioned camera automatic test focusing mechanism has the following problems:

[0005] Although the above-mentioned camera automatic test focusing mechanism can rotate and focus by clamping the lens through the lens clamping module, as the lens clamping module rotates repeatedly, the wire that supplies power to the lens clamping module is very easy to be twisted off during the rotation of the lens clamping module, making it difficult to ensure stable power supply to the lens clamping module. Utility Model Content

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a rotating power distribution focusing mechanism and a camera focusing device that can provide stable power supply.

[0008] A rotary power distribution focusing mechanism comprises a mounting frame, a rotating disk and a clamping focusing assembly; the mounting frame is provided with a rotating cavity, the rotating disk is rotatably disposed in the rotating cavity, and the clamping focusing assembly is mounted on the rotating disk;

[0009] The rotating power distribution focusing mechanism also includes an insulating ring and a power connection spring;

[0010] The insulating ring is coaxially fixed on the rotating disk, and a positive power taking ring and a negative power taking ring are provided on the insulating ring; the positive power taking ring and the negative power taking ring are concentric and arranged at intervals on the periphery of the insulating ring; the power connecting spring is fixed on the mounting frame, and a crimping arm extends toward the insulating ring; the positive contact piece on the crimping arm slides against the positive power taking ring, and the negative contact piece on the crimping arm slides against the negative power taking ring, the positive power taking ring is electrically connected to the positive power connection part of the clamping and focusing assembly, and the negative power taking ring is electrically connected to the negative power connection part of the clamping and focusing assembly.

[0011] In one embodiment, the positive power taking coil is embedded and fixed on the insulating ring; and / or,

[0014] In one embodiment, the mounting plate and the crimping arm are an integrally connected structure.

[0015] In one embodiment, the positive contact comprises a positive fixing portion and two positive contacts connected to each other, the positive fixing portion is fixedly connected to the crimping arm, and each positive contact is slidably abutted against the positive power taking coil.

[0016] In one embodiment, the negative contact comprises a negative fixing portion and two negative contacts connected to each other, the negative fixing portion is fixedly connected to the crimping arm, and each of the negative contacts is slidably abutted against the negative power taking coil.

[0017] In one embodiment, the clamping and focusing assembly includes a first clamping arm and a second clamping arm arranged opposite to each other, the first clamping arm is electrically connected to the positive power coil and the negative power coil respectively; the second clamping arm is electrically connected to the positive power coil and the negative power coil respectively.

[0020] A camera focusing device comprises the rotary power distribution focusing mechanism of any one of the above embodiments.

[0021] Compared with the prior art, the present disclosure has at least the following advantages:

[0022] 1) Because the power connection spring is fixed on the mounting frame, an external power supply can be connected through the power connection spring.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0034] like Figure 1 and Figure 2As shown, a rotary power distribution focusing mechanism 10 of an embodiment includes a mounting frame 100, a rotating disk 200, a clamping focusing assembly 300, an insulating ring 400 and a power connection spring 500; a rotating cavity 110 is opened on the mounting frame 100, the rotating disk 200 is rotatably arranged in the rotating cavity 110, and the clamping focusing assembly 300 is mounted on the rotating disk 200; the insulating ring 400 is coaxially fixed on the rotating disk 200, and a positive power taking coil 410 and a negative power taking coil 420 are provided on the insulating ring 400; the positive power taking coil 410 and the negative power taking coil 420 are connected to each other. The rings 420 are concentrically and spaced apart on the periphery of the insulating ring 400; the power connecting spring 500 is fixed on the mounting frame 100, and a crimping arm 520 extends toward the insulating ring 400; the positive contact piece 530 on the crimping arm 520 slides against the positive power taking ring 410, and the negative contact piece 540 on the crimping arm 520 slides against the negative power taking ring 420, the positive power taking ring 410 is electrically connected to the positive power connection part of the clamping and focusing assembly 300, and the negative power taking ring 420 is electrically connected to the negative power connection part of the clamping and focusing assembly 300.

[0035] It can be understood that because the power connection spring clip 500 is fixed on the mounting frame 100, an external power supply can be connected through the power connection spring clip 500. When the positive contact piece 530 of the crimping arm 520 abuts against the positive power taking ring 410 on the insulating ring 400, the current of the external power supply can be transmitted to the positive power taking ring 410 to supply power to the positive power connection part of the clamping and focusing assembly 300. At the same time, when the negative contact piece 540 of the crimping arm 520 abuts against the negative power taking ring 420 on the insulating ring 400, the current of the external power supply can be transmitted to the negative power taking ring 420 to supply power to the negative power connection part of the clamping and focusing assembly 300. Because the positive power taking coil 410 and the negative power taking coil 420 are concentrically arranged on the periphery of the insulating ring 400, and the insulating ring 400 is coaxially fixed on the rotating disk 200, when the rotating disk 200 rotates in the rotating cavity 110, the crimping arm 520 can still slide and abut against the positive power taking coil 410 through the positive contact piece 530, and can slide and abut against the negative power taking coil 420 through the negative contact piece 540, thereby stably supplying power to the clamping focusing assembly 300.

[0036] It can be understood that compared with the automatic test focusing mechanism of the camera in the prior art, the above-mentioned rotating power distribution focusing mechanism 10, when the rotating disk 200 rotates in the rotating cavity 110, can continuously slide and abut against the positive power taking circle 410 through the positive contact piece 530 of the power connecting spring 500, thereby stably supplying power to the positive power connecting part of the clamping focusing assembly 300, and can continuously slide and abut against the negative power taking circle 420 through the negative contact piece 540 of the power connecting spring 500, thereby stably supplying power to the negative power connecting part of the clamping focusing assembly 300, without the problem of wire breakage, and ultimately the rotating disk 200 can achieve stable power supply to the clamping focusing assembly 300 during the rotation process.

[0037] Combine Figure 2 As shown, in one embodiment, the positive power taking ring 410 is embedded and fixed on the insulating ring 400. It can be understood that by embedding and fixing the positive power taking ring 410 on the insulating ring 400, the positive power taking ring 410 and the insulating ring 400 can be tightly connected together, making it less likely for the insulating ring 400 to slip when rotating.

[0038] Combine Figure 2 As shown, in one embodiment, the negative power taking coil 420 is embedded and fixed on the insulating ring 400. It can be understood that by embedding and fixing the negative power taking coil 420 on the insulating ring 400, the negative power taking coil 420 and the insulating ring 400 can be tightly connected together, making it less likely for the insulating ring 400 to slip when the insulating ring 400 rotates.

[0039] Combine Figure 2 and Figure 3 As shown, in this embodiment, the power connecting spring 500 includes a mounting plate 510, the crimping arm 520, the positive contact 530 and the negative contact 540; the mounting plate 510 is fixed on the mounting frame 100; the crimping arm 520 is connected to the mounting plate 510 and extends toward the insulating ring 400; the positive contact 530 and the negative contact 540 are arranged side by side at the end of the crimping arm 520. It can be understood that by arranging the positive contact 530 and the negative contact 540 side by side at the end of the crimping arm 520, the positive contact 530 can be pressed against the positive power taking coil 410 under the action of the elastic force of the crimping arm 520, so that the positive contact 530 can stably supply power to the positive power taking coil 410, and the negative contact 540 can be pressed against the negative power taking coil 420 under the action of the elastic force of the crimping arm 520, so that the negative contact 540 can stably supply power to the negative power taking coil 420.

[0040] Combine Figure 2 As shown, further, the mounting piece 510 and the crimping arm 520 are integrally connected. It can be understood that by integrally connecting the mounting piece 510 and the crimping arm 520, the structural strength is higher and more durable.

[0041] In one embodiment, the positive contact member 530 includes a positive fixed portion 5310 and two positive contacts 5320 connected to each other. The positive fixed portion 5310 is fixedly connected to the crimping arm 520, and each of the positive contacts 5320 slides against the positive power coil 410. It can be understood that by making the two positive contacts 5320 slide against the positive power coil 410, the contact between the positive contact member 530 and the positive power coil 410 can be effectively increased to improve the conductive efficiency.

[0042] Combine Figure 2 As shown, in one embodiment, the negative contact member 540 includes a connected negative fixed portion and two negative contacts, the negative fixed portion is fixedly connected to the crimping arm 520, and each of the negative contacts slides against the negative power taking coil 420. It can be understood that by making the two negative contacts slide against the negative power taking coil 420, the contact between the negative contact member 540 and the negative power taking coil 420 can be effectively increased to improve the conductive efficiency.

[0043] Combine Figure 3 As shown, in one embodiment, the clamping and focusing assembly 300 includes a first clamping arm 310 and a second clamping arm 320 arranged opposite to each other, wherein the first clamping arm 310 is electrically connected to the positive power coil 410 and the negative power coil 420, respectively; and the second clamping arm 320 is electrically connected to the positive power coil 410 and the negative power coil 420, respectively. It can be understood that since the first clamping arm 310 is powered by the positive power coil 410 and the negative power coil 420, and the second clamping arm 320 is powered by the positive power coil 410 and the negative power coil 420, the first clamping arm 310 and the second clamping arm 320 can move relative to each other to clamp the camera.

[0044] Combine Figure 3 and Figure 4 As shown, in one embodiment, the first clamping arm 310 includes a first push driver 3110 and a first clamping plate 3120; the first push driver 3110 is fixedly connected to the rotating disk 200, and the first clamping plate 3120 is provided on the telescopic rod of the first push driver 3110, and the first push driver 3110 is electrically connected to the positive power coil 410 and the negative power coil 420, respectively. It can be understood that by electrically connecting the first push driver 3110 to the positive power coil 410 and the negative power coil 420, respectively, the first push driver 3110 can obtain a stable power supply, and the telescopic rod of the first push driver 3110 pushes the first clamping plate 3120, so that the first clamping plate 3120 can firmly press against the first side of the camera.

[0045] Combine Figure 3As shown, in one embodiment, the second clamping arm 320 includes a second push driver 3210 and a second clamping plate 3220; the second push driver 3210 is fixedly connected to the rotating disk 200, and the second clamping plate 3220 is provided on the telescopic rod of the second push driver 3210, and the second push driver 3210 is electrically connected to the positive power coil 410 and the negative power coil 420 respectively. It can be understood that by electrically connecting the second push driver 3210 to the positive power coil 410 and the negative power coil 420 respectively, the second push driver 3210 can obtain a stable power supply, and the telescopic rod of the second push driver 3210 pushes the second clamping plate 3220 so that the second clamping plate 3220 can firmly abut the second side of the camera.

[0046] In one embodiment, the electrical connection may be a wired connection, such as a wire connection or a circuit board connection, etc., which is not limited here and can be replaced by those skilled in the art as needed.

[0047] Combine Figure 1 As shown, the present disclosure also provides a camera focusing device, including a rotating power distribution focusing mechanism 10 of any of the above embodiments. It can be understood that by applying the rotating power distribution focusing mechanism 10 of the present disclosure to the camera focusing device, when the rotating disk 200 rotates in the rotating cavity 110, the positive contact piece 530 of the power-connecting spring 500 can continuously slide against the positive power-taking coil 410, thereby stably supplying power to the positive power-connecting part of the clamping focusing assembly 300, and the negative contact piece 540 of the power-connecting spring 500 can continuously slide against the negative power-taking coil 420, thereby stably supplying power to the negative power-connecting part of the clamping focusing assembly 300, without the problem of wire breaking, and ultimately enabling the rotating disk 200 to achieve stable power supply to the clamping focusing assembly 300 during the rotation process.

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

[0049] 1) Because the power connection spring 500 is fixed on the mounting frame 100, an external power supply can be connected through the power connection spring 500. When the positive contact piece 530 of the crimping arm 520 abuts against the positive power taking coil 410 on the insulating ring 400, the current of the external power supply can be transmitted to the positive power taking coil 410 to supply power to the positive power connection part of the clamping and focusing assembly 300. At the same time, when the negative contact piece 540 of the crimping arm 520 abuts against the negative power taking coil 420 on the insulating ring 400, the current of the external power supply can be transmitted to the negative power taking coil 420 to supply power to the negative power connection part of the clamping and focusing assembly 300. Because the positive power taking coil 410 and the negative power taking coil 420 are concentrically arranged on the periphery of the insulating ring 400, and the insulating ring 400 is coaxially fixed on the rotating disk 200, when the rotating disk 200 rotates in the rotating cavity 110, the crimping arm 520 can still slide and abut against the positive power taking coil 410 through the positive contact piece 530, and can slide and abut against the negative power taking coil 420 through the negative contact piece 540, thereby stably supplying power to the clamping focusing assembly 300.

[0050] 2) Compared with the automatic test focusing mechanism of the camera in the prior art, the above-mentioned rotating power distribution focusing mechanism 10, when the rotating disk 200 rotates in the rotating cavity 110, can continuously slide and abut against the positive power taking circle 410 through the positive contact piece 530 of the power connecting spring 500, thereby stably supplying power to the positive power connection part of the clamping focusing assembly 300, and can continuously slide and abut against the negative power taking circle 420 through the negative contact piece 540 of the power connecting spring 500, thereby stably supplying power to the negative power connection part of the clamping focusing assembly 300, without the problem of wire breakage, and ultimately can enable the rotating disk 200 to achieve stable power supply to the clamping focusing assembly 300 during the rotation process.

[0051] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
