[0002] Currently, with the rise of new energy vehicles, in order to improve the use safety and intelligence level of new energy vehicles, and to ensure the factory quality of cameras and improve the production efficiency of cameras, most manufacturers have produced camera focusing devices.

[0003] However, most camera focusing devices require manual placement of the camera into the focusing slot before focusing on the camera. This results in difficulty in ensuring that the camera can be stably positioned on the focusing device during adjustment when manually fixing and installing the camera, thus affecting the accuracy of camera focusing. Summary of the Utility Model

[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a vacuum adsorption focusing mechanism and a camera focusing device for focusing a camera by vacuum adsorption.

[0005] The purpose of the present disclosure is achieved through the following technical solutions:

[0006] A vacuum adsorption focusing mechanism includes an adsorption bracket and an adsorption disc. The adsorption disc is disposed at the central position of the adsorption bracket. The adsorption bracket is provided with a plurality of ramp bosses, and each ramp boss is provided with a vacuum suction cavity at the bottom. The inner frame of the adsorption disc is provided with a plurality of vacuum adsorption areas, and the plurality of vacuum adsorption areas are provided with adsorption channels. An accommodation cavity is opened at the central position of the adsorption disc. The plurality of ramp bosses are correspondingly disposed on the plurality of vacuum adsorption areas one by one, and the vacuum suction cavity communicates with the accommodation cavity through the adsorption channel.

[0007] In one embodiment, the plurality of vacuum adsorption areas are arranged along the diagonal of the adsorption disc.

[0008] In one embodiment, the adsorption disc is provided with a plurality of connecting crossbars. One side of each of the plurality of connecting crossbars extends to the corresponding vacuum adsorption area one by one, and the other side of each of the plurality of connecting crossbars extends to the accommodation cavity.

[0009] In one embodiment, the adsorption disc is provided with a central cylinder. The central cylinder is disposed at the central position of the adsorption disc and is connected to the corresponding vacuum adsorption area through each connecting crossbar. The accommodation cavity is opened in the central cylinder.

[0010] In one embodiment, a plurality of adsorption holes are formed in the inner peripheral wall of the central cylinder, and each adsorption hole is arranged symmetrically with another adsorption hole, and each adsorption hole is correspondingly communicated with an adsorption channel.

[0011] In one embodiment, a convex ring is arranged on the inner peripheral wall of the central cylinder, and the convex ring is arranged around the inner peripheral wall of the central cylinder.

[0012] In one embodiment, the adsorption disc, a plurality of connecting cross bars and the central cylinder are of an integrally formed structure.

[0013] In one embodiment, the adsorption channel extends into the inner cavities of a plurality of connecting cross bars and is communicated with the placement cavity.

[0014] In one embodiment, a support circular cavity is formed in the adsorption support, and each ramped boss is arranged symmetrically with another ramped boss on the inner peripheral wall of the support circular cavity.

[0015] A camera focusing device includes the vacuum adsorption focusing mechanism described in any one of the above embodiments.

[0016] Compared with the prior art, the present disclosure has at least the following advantages:

[0017] 1) By arranging a plurality of ramped bosses on the adsorption support and simultaneously forming a vacuum suction cavity at the bottom of the ramped bosses, the adsorption support sucks air through the vacuum suction cavity, so that there is no air remaining in the vacuum suction cavity. At the same time, a plurality of vacuum adsorption areas are arranged inside the adsorption disc, and the ramped bosses are correspondingly arranged on the vacuum adsorption areas, so that the vacuum suction cavities of the ramped bosses are communicated with the adsorption channels of the vacuum adsorption areas.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following further describes this disclosure in detail with reference to specific embodiments:

[0030] As Figure 1 shown, a vacuum adsorption focusing mechanism 10 of an embodiment includes an adsorption bracket 100 and an adsorption disc 200. The adsorption disc 200 is disposed at the central position of the adsorption bracket 100. The adsorption bracket 100 is provided with a plurality of ramp bosses 110. A vacuum suction cavity 1110 is formed at the bottom of each ramp boss 110. A plurality of vacuum adsorption zones 210 are provided in the inner frame of the adsorption disc 200. Adsorption channels 2110 are formed in the plurality of vacuum adsorption zones 210. An accommodation cavity 220 is formed at the central position of the adsorption disc 200. The plurality of ramp bosses 110 are correspondingly disposed on the plurality of vacuum adsorption zones 210 one by one. The vacuum suction cavity 1110 communicates with the accommodation cavity 220 through the adsorption channels 2110.

[0031] It can be understood that by providing a plurality of ramp bosses 110 on the adsorption bracket 100 and forming a vacuum suction cavity 1110 at the bottom of the ramp bosses 110, the adsorption bracket 100 sucks air through the vacuum suction cavity 1110, so that there is no air retained in the vacuum suction cavity 1110. At the same time, a plurality of vacuum adsorption zones 210 are provided in the inner frame of the adsorption disc 200, and the ramp bosses 110 are hermetically disposed on the vacuum adsorption zones 210 one by one, so that the vacuum suction cavity 1110 of the ramp bosses 110 communicates with the adsorption channels 2110 of the vacuum adsorption zones 210. At the same time, the accommodation cavity 220 communicates with the adsorption channels 2110 and the vacuum adsorption cavity. When the camera is placed in the accommodation cavity 220 for focusing, the adsorption bracket 100 sucks air through the vacuum suction cavity 1110. At the same time, the vacuum suction cavity 1110 communicates with the adsorption channels 2110, and the adsorption channels 2110 communicate with the accommodation cavity 220. When the camera is placed in the accommodation cavity 220, due to the principle of vacuum adsorption, the pressure in the adsorption channels 2110 is reduced, so that the camera can be stably installed in the accommodation cavity 220.

[0032] It can be understood that, compared with the existing technology, the above-mentioned vacuum adsorption focusing mechanism 10 sets a vacuum suction cavity 1110 in the adsorption bracket 100, and the adsorption disc 200 is provided with an adsorption channel 2110. When the vacuum suction cavity 1110 of the adsorption bracket 100 sucks air, the adsorption channel 2110 communicated with it will change the pressure of the adsorption channel 2110 due to vacuum suction, so that the camera placed in the placement cavity 220 is fixed in the placement cavity 220 for focusing processing, avoiding the influence on the focusing accuracy of the camera caused by manually fixing the camera for focusing.

[0033] As Figure 2 shown, specifically, several vacuum adsorption areas 210 are arranged along the diagonal of the adsorption disc 200. It can be understood that arranging the vacuum adsorption areas 210 diagonally on the adsorption disc 200 enables the adsorption channels 2110 opened in the multiple vacuum adsorption areas 210 to communicate with the placement cavity 220 in multiple directions. When the camera is placed in the placement cavity 220 for focusing, the multiple adsorption channels 2110 of the multiple vacuum adsorption areas 210 can stably adsorb the camera for focusing.

[0034] As Figure 2 shown, specifically, the adsorption disc 200 is provided with several connecting crossbars 230. One side of the several connecting crossbars 230 extends to the vacuum adsorption areas 210 one by one, and the other side of the several connecting crossbars 230 extends to the placement cavity 220. It can be understood that by setting several connecting crossbars 230 on the adsorption disc 200, with one side of the connecting crossbars 230 connected to the corresponding vacuum adsorption areas 210 and the other side connected to the placement cavity 220, the overall structure and stability of the adsorption disc 200 can be enhanced. By firmly connecting the vacuum adsorption areas 210 and the placement cavity 220 with the connecting crossbars 230, the situation of displacement and vibration during the focusing process is reduced, ensuring the stable position of the adsorption disc 200.

[0035] As Figure 2 shown, in one of the embodiments, the adsorption channel 2110 extends into the inner cavity of the several connecting crossbars 230 and communicates with the placement cavity 220. It can be understood that by extending the adsorption channel 2110 into the inner cavity of the connecting crossbars 230 and communicating with the placement cavity 220, since the adsorption channel 2110 is connected to the vacuum adsorption cavity, when the vacuum adsorption cavity extracts air, the air in the adsorption channel 2110 will be extracted by the vacuum adsorption cavity, and the adsorption channel 2110 extends and communicates with the placement cavity 220, changing the pressure around the placement cavity 220, so that the camera can be fixed in the placement cavity 220.

[0036] Combined with Figure 2 and Figure 3As shown, in one embodiment, the adsorption bracket 100 is provided with a bracket circular cavity 120. Each ramp boss 110 and another ramp boss 110 are symmetrically arranged on the inner peripheral wall of the bracket circular cavity 120. It can be understood that the ramp bosses 110 are arranged on the inner peripheral wall of the bracket circular cavity 120, and each ramp boss 110 and another ramp boss 110 are arranged according to the symmetry axis of the bracket circular cavity 120, so that the vacuum suction cavities 1110 at the bottom of each ramp boss 110 are also symmetrically arranged with respect to the bracket circular cavity 120. Also, because the vacuum suction cavities 1110 are connected to the adsorption channels 2110, when the vacuum suction cavities 1110 suck air, the adsorption channels 2110 are driven to suck air. Since the vacuum suction cavities 1110 are symmetrically arranged, the stability of the vacuum adsorption focusing mechanism 10 is stabilized, making the focusing camera more stably adsorbed in the placement cavity 220 when placed in it.

[0037] Combined with Figure 2 and Figure 4 As shown, in one embodiment, the adsorption disc 200 is provided with a central cylinder 240. The central cylinder 240 is arranged at the center of the adsorption disc 200 and is connected to the corresponding vacuum adsorption area 210 through each connecting cross bar 230. The placement cavity 220 is opened in the central cylinder 240. It can be understood that the adsorption disc 200 is provided with a central cylinder 240 and is arranged at the center of the adsorption disc 200, enabling the camera to be conveniently focused according to the central position. At the same time, the central cylinder 240 is connected to the vacuum adsorption area 210 by the connecting cross bars 230, improving the stability of the central cylinder 240 and stabilizing the structure of the central cylinder 240.

[0038] Combined with Figure 2 and Figure 4 As shown, specifically, a number of adsorption holes 2410 are opened on the inner peripheral wall of the central cylinder 240. Each adsorption hole 2410 and another adsorption hole 2410 are arranged according to the symmetry axis of the placement cavity 220. The number of adsorption holes 2410 is in one-to-one correspondence and connected to the adsorption channels 2110. It can be understood that by opening a number of adsorption holes 2410 on the inner peripheral wall of the central cylinder 240, the surface area and effect of vacuum adsorption can be increased. At the same time, the adsorption holes 2410 are arranged symmetrically in the placement cavity 220, ensuring that the adsorption force can act evenly on each part of the camera, thereby improving the stability and reliability of the adsorption disc 200. The connection between the adsorption holes 2410 and the adsorption channels 2110 enables the adsorption holes 2410 to act on the periphery of the adsorption holes 2410 through the vacuum of the adsorption channels 2110.

[0039] Such as Figure 3As shown, in one embodiment, a convex ring 2420 is provided on the inner peripheral wall of the central cylinder 240. The convex ring 2420 is arranged around the inner peripheral wall of the central cylinder 240. It can be understood that by providing the convex ring 2420 on the inner peripheral wall of the central cylinder 240, when the camera needs to be focused, the convex ring 2420 will catch the top of the camera, avoiding the influence on the focusing effect due to the camera being embedded too deep into the central cylinder 240.

[0040] As Figure 5 shown, in one embodiment, the suction disc 200, several connecting cross bars 230 and the central cylinder 240 are of an integrally formed structure. It can be understood that by designing the suction disc 200 as an integrally formed structure, the suction disc 200 is made by a single forming process, so that there are no parts that need to be spliced and assembled on the suction disc 200, reducing the potential structural weaknesses and failure points of the suction disc 200, making the structural stability of the suction disc 200 better. The integrally formed structure can ensure the geometric shape and consistency of the suction disc 200, ensuring the structural stability of the suction disc 200 during the camera focusing process, and thus ensuring the accuracy of camera focusing.

[0041] A camera focusing device includes the vacuum suction focusing mechanism 10 of any of the above embodiments. It can be understood that by providing a vacuum suction chamber 1110 in the suction bracket 100 and arranging a suction channel 2110 in the suction disc 200, when the vacuum suction chamber 1110 of the suction bracket 100 sucks air, the suction channel 2110 communicated with it will change the pressure of the suction channel 2110 due to the vacuum suction, so that the camera placed in the placement cavity 220 is fixed in the placement cavity 220 for focusing processing, avoiding the influence on the accuracy of camera focusing due to manually fixing the camera for focusing.

[0042] Compared with the prior art, the present disclosure has at least the following advantages:

[0043] 1) By providing several ramp bosses on the suction bracket and arranging a vacuum suction chamber at the bottom of the ramp bosses, when the suction bracket sucks air through the vacuum suction chamber, there is no air left in the vacuum suction chamber. At the same time, several vacuum suction areas are arranged in the inner frame of the suction disc, and the ramp bosses are correspondingly arranged on the vacuum suction areas, so that the vacuum suction chamber of the ramp bosses is communicated with the suction channels of the vacuum suction areas. At the same time, the placement cavity is communicated with the vacuum suction chamber through the suction channels. When the camera is placed in the placement cavity for focusing, the placement cavity sucks air through the vacuum suction chamber, that is, the vacuum suction chamber is communicated with the suction channels, and the suction channels are communicated with the placement cavity. When the camera is placed in the placement cavity, due to the principle of vacuum suction, the suction channels form a negative pressure, so that the camera can be stably installed in the placement cavity.

[0044] 2) Compared with the existing technologies, in the above-mentioned vacuum adsorption focusing mechanism 10, by providing a vacuum suction cavity 1110 in the adsorption bracket 100 and an adsorption channel 2110 in the adsorption disc 200, when the vacuum suction cavity 1110 of the adsorption bracket 100 sucks air, the pressure of the adsorption channel 2110 communicated with it will change due to vacuum suction, so that the camera placed in the placement cavity 220 is fixed in the placement cavity 220 for focusing processing, avoiding the influence on the focusing accuracy of the camera caused by manually fixing the camera for focusing.

[0045] The above-described embodiments merely represent several implementation manners of the present disclosure, and the description thereof 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.
