[0032] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.
[0033] Please see Figure 1 and Figure 2 This application provides a steering bracket 100 for a camera module. The steering bracket 100 is specifically applied in a periscope camera module. The steering bracket 100 is used to mount an optical steering element. The steering bracket 100 can move within the periscope camera module to enable optical image stabilization. The optical steering element can be a prism or other optical element that can bend light at a certain angle.
[0034] Please refer to the above. Figure 3 and Figure 4The turning support 100 comprises a body 10 and two protrusions 20 arranged on opposite sides of the body 10 respectively. At least one of the two protrusions 20 is provided with a ball groove 22. The ball groove 22 comprises a groove bottom 222 and a groove wall 224 connected with the groove bottom 222. The groove wall 224 comprises an abutting surface 2242 connected with the groove bottom 222. The turning support 100 satisfies the following condition formula: 90° < a ≤ 140°, wherein a is the included angle between the abutting surface 2242 and the groove bottom 222. Preferably, 130° ≤ a ≤ 140°, and further, the included angle a between the abutting surface 2242 and the groove bottom 222 is 135°. In the embodiment, the ball groove 22 is arranged on one of the protrusions 20. It can be understood that in other embodiments, the ball groove 22 can also be arranged on the other protrusion 20, or the ball groove 22 can also be arranged on both of the protrusions 20. The specific arrangement can be set according to the actual situation, and the embodiment of the present application does not make specific limitation.
[0035] Thus, the turning support 100 of the embodiment can accommodate the ball (not shown in the figure) through the ball groove 22 arranged on the protrusion 20, so that the turning support 100 can realize displacement through the ball-ball groove 22 structure. When the ball groove 22 accommodates the ball, by limiting the range of the included angle a between the abutting surface 2242 and the groove bottom 222, the abutting surface 2242 is arranged obliquely relative to the groove bottom 222. The abutting surface 2242 of the ball groove 22 can abut against the ball, so that the ball is spaced apart from the groove bottom 222 and forms a supporting action on the ball, so that the turning support 100 can realize displacement through the ball. At the same time, by limiting the range of the included angle a between the abutting surface 2242 and the groove bottom 222, the range of the included angle a between the abutting surface 2242 and the groove bottom 222 is reasonably configured. When the terminal equipment using the turning support 100 falls and impacts, the abutting surface 2242 obliquely relative to the groove bottom 222 can buffer the mechanical impact force, so that the abutting point where the ball contacts the abutting surface 2242 is less concave, thereby reducing the probability of deformation of the ball groove 22, improving the reliability of the ball groove 22, and further improving the anti-deformation ability of the turning support 100, thereby improving the reliability of the turning support 100. In addition, by reasonably configuring the range of the included angle a between the abutting surface 2242 and the groove bottom 222, it is beneficial to improve the strength of the protrusion 20, thereby further improving the reliability of the turning support 100.
[0036] In the embodiment, the groove wall 224 further comprises a connecting surface 2244 connected with the bearing surface 2242 and the groove bottom 222, and the steering bracket 100 further satisfies the following conditional expression: 90°≤b≤120°, b
[0037] In the embodiment, the groove wall 224 comprises three bearing surfaces 2242 and three connecting surfaces 2244, and the three bearing surfaces 2242 and the three connecting surfaces 2244 are connected in sequence and staggered. Among them, the groove bottom 222 is substantially an equilateral triangle, and the connecting surface 2244 is substantially a triangle. In this way, by limiting the number of the bearing surface 2242 and the connecting surface 2244 to be three, the three bearing surfaces 2242 form a three-point support for the ball, ensuring that the ball groove 22 can stably support the ball.
[0038] In the embodiment, the length of the end of the bearing surface 2242 away from the groove bottom 222 in the direction parallel to the groove bottom 222 is greater than the length of the end of the connecting surface 2244 away from the groove bottom 222 in the direction parallel to the groove bottom 222. In this way, by limiting the length of the bearing surface 2242 to be greater than the length of the connecting surface 2244, the size of the groove opening of the ball groove 22 is greater than the size of the groove bottom 222, so that the ball can be placed deeper in the ball groove 22, avoiding the ball from easily escaping from the ball groove 22, and ensuring the stability of the steering bracket 100.
[0039] In the embodiment, the material of the convex body 20 is any one of LCP (Liquid Crystal Polymer), NTP (Triphenyl Phosphate), and PC (Polycarbonate). It can be understood that the body 10 can be consistent with the material of the convex body 20, or can be inconsistent with the material of the convex body 20. When the body 10 is consistent with the material of the convex body 20, the body 10 and the convex body 20 can be integrally formed as the steering bracket 100. In this way, by limiting the material of the convex body 20, the structural strength of the convex body 20 is improved, and the structural strength of the steering bracket 100 is further improved.
[0040] In the embodiment, the body 10 is provided with an assembly groove 12 for assembling the optical turning element. The assembly groove 12 includes a bottom wall 122 and two side walls 124 respectively arranged on two opposite sides of the bottom wall 122. The two side walls 124 are both substantially triangular in shape to fit the assembly of the triangular prism. In this way, the assembly of the triangular prism is realized by providing the assembly groove 12 on the body 10.
[0041] The application also provides a periscopic camera module (not shown in the figure). The periscopic camera module of the embodiment includes the turning support 100 of the above embodiment. It can be understood that the periscopic camera module of the embodiment can also include a housing (not shown in the figure), a lens (not shown in the figure), a prism (not shown in the figure), a driving unit (not shown in the figure), a photosensitive chip (not shown in the figure), etc. The lens and the turning support 100 are arranged in the housing along the optical axis. The prism is assembled in the assembly groove 12 of the turning support 100. The turning support 100 is movably arranged in the housing through the ball-ball groove 22 structure. The driving unit is arranged in the housing and connected with the lens and / or the turning support 100. The driving unit is used to drive the lens and / or the turning support 100 to move in the housing, so that the periscopic camera module realizes optical image stabilization. The photosensitive chip is arranged in the housing. The photosensitive chip is used to receive the optical signal passing through the prism and the lens and convert it into an electrical signal for imaging.
[0042] In this way, the turning support 100 of the above periscopic camera module is movably arranged in the housing through the ball-ball groove 22 structure by providing the ball groove 22 on the protruding body 20. The ball groove 22 can accommodate the ball, so that the turning support 100 is movably arranged in the housing through the ball-ball groove 22 structure. When the ball groove 22 accommodates the ball, the range of the included angle a between the bearing surface 2242 and the groove bottom 222 is limited, so that the bearing surface 2242 is arranged obliquely relative to the groove bottom 222. The bearing surface 2242 of the ball groove 22 can abut against the ball, so that the ball is spaced apart from the groove bottom 222 and forms a supporting action on the ball, so that the turning support 100 can be movably arranged in the housing through the ball. At the same time, by limiting the range of the included angle a between the bearing surface 2242 and the groove bottom 222, the range of the included angle a between the bearing surface 2242 and the groove bottom 222 is reasonably configured. When the terminal device using the periscopic camera module falls and impacts, the oblique bearing surface 2242 relative to the groove bottom 222 can buffer the mechanical impact force, so that the bearing point where the ball contacts the bearing surface 2242 is less concave, thereby reducing the probability of deformation of the ball groove 22, improving the reliability of the ball groove 22, and further improving the anti-deformation ability of the turning support 100, thereby improving the reliability of the turning support 100. In addition, by reasonably configuring the range of the included angle a between the bearing surface 2242 and the groove bottom 222, the strength of the protruding body 20 is improved, thereby further improving the reliability of the periscopic camera module.
[0043] The embodiment of the present application also provides a terminal device. The terminal device of the embodiment includes the periscopic camera module as above. The terminal device of the embodiment can be a mobile phone. It can be understood that in other embodiments, the terminal device can also be a vehicle-mounted recorder, a security monitoring device, an AR device, a VR device, a vehicle, a tablet computer, a smart watch, a sweeping robot, and other devices with a periscopic camera module.
[0044] The periscopic camera module of the terminal device described above, the steering support 100 of the periscopic camera module is adapted to accommodate the ball by opening the ball groove 22 on the convex body 20, so that the steering support 100 realizes displacement through the ball-ball groove 22 structure; when the ball groove 22 accommodates the ball, by limiting the range of the included angle a between the bearing surface 2242 and the groove bottom 222, the bearing surface 2242 is inclined relative to the groove bottom 222, the bearing surface 2242 of the ball groove 22 can abut the ball, so that the ball is spaced apart from the groove bottom 222 and forms a supporting action on the ball, so that the steering support 100 can realize displacement through the ball; at the same time, by limiting the range of the included angle a between the bearing surface 2242 and the groove bottom 222, the range of the included angle a between the bearing surface 2242 and the groove bottom 222 is reasonably configured, when the terminal device falls and impacts, the bearing surface 2242 inclined relative to the groove bottom 222 can buffer the mechanical impact force, so that the bearing point of the ball in contact with the bearing surface 2242 is less concave, thereby reducing the probability of deformation of the ball groove 22, improving the reliability of the ball groove 22, and further improving the anti-deformation ability of the steering support 100, thereby improving the reliability of the steering support 100. In addition, by reasonably configuring the range of the included angle a between the bearing surface 2242 and the groove bottom 222, it is beneficial to improve the strength of the convex body 20, thereby further improving the reliability of the periscopic camera module.
