[0037] The lens module according to the embodiments of the present application is described below with reference to Figures 1 to 10
[0038] For example Figure 2 And Figure 4 As shown, the lens module according to the embodiment of the present application comprises a bearing seat, a base 200, a suspension assembly 400 and a driving assembly. The bearing part 100 is annular and is used for bearing a lens. The base 200 comprises a main body part 210 and a fixing part 220. The main body part 210 is annular and has a receiving cavity matching the bearing part 100. The receiving cavity frames the bearing part 100. The side edge of the main body part 210 is provided with a notch. The fixing part 220 is fixedly connected to the side edge of the notch and the main body part 210. The bearing part 100 is provided with a driving member 110 which protrudes from the notch. The suspension assembly 400 connects the base 200 and the bearing part 100. The bearing part 100 is suspended in the receiving cavity through the suspension assembly 400. The driving assembly is fixedly arranged on the fixing part 220. The driving assembly drives the driving member 110 to drive the bearing part 100 to move in the receiving cavity.
[0039] For example Figure 2 and Figure 4 As shown, the bearing part 100 is annular and internally provided with an annular cavity which is used for bearing a circular lens. The shape of the bearing part 100 is annular, which can reduce unnecessary volume and only keep the necessary part. The base 200 comprises a main body part 210 and a fixing part 220. The main body part 210 is annular and internally provided with a receiving cavity matching the bearing part 100. The receiving cavity frames the bearing part 100. The side edge of the main body part 210 is provided with a notch. The fixing part 220 is fixedly connected to the side edge of the notch and the main body part 210. The bearing part 100 is provided with a driving member 110 which protrudes from the notch. The driving assembly is fixedly arranged on the fixing part 220. The driving assembly drives the driving member 110 to drive the bearing part 100 to move in the receiving cavity. The suspension assembly 400 connects the base 200 and the bearing part 100, so that the bearing part 100 is suspended in the receiving cavity of the base 200, and the driving assembly is easy to drive the bearing part 100 to move to realize focusing. Furthermore, the suspension assembly 400 has a certain elasticity, which can reset the bearing part 100 after the driving assembly drives the bearing part 100.
[0040] By arranging the notch and the driving member 110, the driving member 110 protrudes from the notch of the base 200 and is driven by the driving assembly, which maximally reduces the volume and weight of the lens module. The base 200 is overall semicircular and semiquadratic. The driving assembly is arranged on one side of the quadratic part. The semicircular part is mainly used for framing the bearing part 100. The semiquadratic part is used for framing the bearing part 100 and mounting the driving assembly on the fixing part 220, so that the driving assembly can drive the bearing part 100 to move to realize the function of lens focusing. Furthermore, the main body part 210 and the fixing part 220 of the base 200 are integrally formed.
[0041] According to the lens module provided in the embodiments of the present application, at least the following beneficial effects can be achieved: the volume of the lens module is reduced, the bearing part 100 is suspended in the accommodating cavity in the base 200, and the driving assembly is easy to drive the bearing part 100. Meanwhile, the driving assembly is arranged on the side of the base 200, the height of the lens module is reduced, the space occupied by the lens module is reduced, and the miniaturization of the camera equipment is facilitated.
[0042] In some embodiments of the present application, the suspension assembly 400 comprises a suspension part 410 and a connecting part 420, the suspension part 410 is connected with the bearing part 100, the connecting part 420 is fixedly arranged on the base 200 and elastically connected with the suspension part 410, and the bearing part 100 is suspended in the accommodating cavity through the suspension part 410 and the connecting part 420.
[0043] For example Figure 2 and Figure 4 As shown in the figures, the suspension assembly 400 comprises a suspension part 410 and a connecting part 420, the suspension part 410 is annular and matched with the shape of the bearing seat, the suspension part 410 is connected with the top surface and the bottom surface of the bearing part 100, and the connecting part 420 connects the suspension part 410 and the base 200, so that the bearing part 100 can be suspended in the accommodating cavity through the suspension part 410 and the connecting part 420, and the driving assembly is easy to drive the bearing part 100.
[0044] The suspension part 410 is annular and connected with the top surface and the bottom surface of the bearing part 100, so that the suspension part 410 has a larger connection area with the bearing part 100 and is more stable in connection. The connecting part 420 connects the end of the suspension part 410 close to the driving assembly and the fixed part 220 of the base 200, and suspends the bearing part 100 in the accommodating cavity of the base 200. The connecting part 420 is arranged on the fixed part 220 in the shape of an airplane wing, has a larger connection area and is more stable in connection.
[0045] In some embodiments of the present application, the suspension part 410 is annular and connected with the top surface and / or the bottom surface of the bearing part 100.
[0046] For example Figure 2 and Figure 3 As shown in the figures, the suspension part 410 is annular and connected with the top surface and the bottom surface of the bearing part 100, the connection area of the suspension part 410 with the bearing part 100 is increased by arranging the suspension part 410 in the shape of a ring, and the bearing part 100 is better suspended in the accommodating cavity of the base 200 by being connected with the top surface and the bottom surface of the bearing part 100 at the same time, so that the driving assembly is easy to drive the bearing part 100. Meanwhile, the connecting part 420 is elastically arranged, and the bearing part 100 can be reset by the elasticity of the connecting part 420 when the driving force of the driving assembly disappears.
[0047] In some embodiments of the present application, the suspension assembly 400 further comprises a limiting portion 430, and the side edge of the main body portion 210 is provided with a groove 211, and the limiting portion 430 is protrudingly arranged in the groove 211.
[0048] For example Figure 2 and Figure 4 As shown in FIG. 4, the suspension assembly 400 further comprises a limiting portion 430, and the side edge of the main body portion 210 is provided with a groove 211, and the limiting portion 430 is protrudingly arranged in the groove 211. Through the arrangement of the limiting portion 430 and the groove 211, the bearing portion 100 is not easy to shake and move, and can be stably suspended in the accommodating cavity of the base 200.
[0049] The limiting portion 430 is arranged on the suspension portion 410 of the suspension assembly 400, and is symmetrically arranged on both sides of the suspension portion 410. The groove 211 is also symmetrically arranged on both sides of the main body portion 210, and the limiting portion 430 is embedded in the groove 211, so that the horizontal position of the suspension portion 410 of the suspension assembly 400 can be fixed, and the movement in the vertical direction is not affected, and the bearing portion 100 can move up and down under the driving of the driving assembly to achieve focusing.
[0050] In some embodiments of the present application, the driving assembly comprises a memory alloy wire 300, and the fixing portion 220 is arranged on both sides of the notch. Both ends of the memory alloy wire 300 are fixedly arranged on the fixing portion 220, and the middle portion of the memory alloy wire 300 is hooked on the driving member 110. The driving assembly drives the driving member 110 to move through the contraction of the memory alloy wire 300 under power.
[0051] For example Figures 5 to 10 As shown in FIG. 4, the driving assembly is a memory alloy wire 300. The fixing portion 220 is arranged on both sides of the notch, and the memory alloy wire 300 is arranged in a V shape, both ends of which are fixedly arranged on the fixing portion 220, and the middle portion is in abutment with the driving member 110 and is hooked on the driving member 110. When the memory alloy wire 300 is contracted under power, the driving member 110 can be driven to move, and the movement of the driving member 110 drives the bearing portion 100 to move together, so that the lens can move to achieve the effect of focusing. The memory alloy wire 300 can be arranged at the top of the driving member 110, for example Figure 5 and Figure 6 As shown in FIG. 4, the driving assembly is a memory alloy wire 300. The fixing portion 220 is arranged on both sides of the notch, and the memory alloy wire 300 is arranged in a V shape, both ends of which are fixedly arranged on the fixing portion 220, and the middle portion is in abutment with the driving member 110 and is hooked on the driving member 110. When the memory alloy wire 300 is contracted under power, the driving member 110 can be driven to move, and the movement of the driving member 110 drives the bearing portion 100 to move together, so that the lens can move to achieve the effect of focusing. The memory alloy wire 300 can be arranged at the top of the driving member 110, for example Figure 7 and Figure 8 As shown in FIG. 4, the driving assembly is a memory alloy wire 300. The fixing portion 220 is arranged on both sides of the notch, and the memory alloy wire 300 is arranged in a V shape, both ends of which are fixedly arranged on the fixing portion 220, and the middle portion is in abutment with the driving member 110 and is hooked on the driving member 110. When the memory alloy wire 300 is contracted under power, the driving member 110 can be driven to move, and the movement of the driving member 110 drives the bearing portion 100 to move together, so that the lens can move to achieve the effect of focusing. The memory alloy wire 300 can be arranged at the top of the driving member 110, for example Figure 9 and Figure 10As shown. When the memory alloy wire 300 is arranged at the top of the driving member 110, the memory alloy wire 300 can be driven to contract by being electrified to drive the driving member 110 to move downward, and when the memory alloy wire 300 is arranged at the bottom of the driving member 110, the memory alloy wire 300 can be driven to contract by being electrified to drive the driving member 110 to move upward.
[0052] Further, the fixed part 220 is provided with a terminal 310 made of a metal sheet, and the end of the memory alloy wire 300 is fixedly connected to the terminal 310, and the terminal 310 supplies power to the memory alloy wire 300 so that the memory alloy wire 300 can be driven to contract to generate driving force.
[0053] The driving is realized by the memory alloy wire 300, the volume of the memory alloy wire 300 is smaller, the driving force is larger, the driving of the bearing part 100 can be better realized, and the volume of the driving assembly can be reduced, which is beneficial to the miniaturization of the lens module.
[0054] In some embodiments of the present application, the memory alloy wire 300 is provided with two groups, one group of memory alloy wires 300 abuts against the top of the driving member 110 and the two ends thereof are located at the bottom of the fixed part 220, and the other group of memory alloy wires 300 abuts against the bottom of the driving member 110 and the two ends thereof are located at the top of the fixed part 220.
[0055] For example Figure 9 and Figure 10 As shown, the memory alloy wire 300 is provided with two groups, one group of memory alloy wires 300 abuts against the top of the driving member 110, and the other group of memory alloy wires 300 abuts against the bottom of the driving member 110. The two groups of memory alloy wires 300 are symmetrically arranged on the upper and lower sides of the driving member 110. When it is needed to drive the bearing part 100 to move upward, the memory alloy wire 300 abutting against the top of the driving member 110 is relaxed, and the memory alloy wire 300 abutting against the bottom of the driving member 110 is contracted to drive the bearing part 100 to move upward to realize lens focusing. When it is needed to drive the bearing part 100 to move downward, the memory alloy wire 300 abutting against the top of the driving member 110 is contracted, and the memory alloy wire 300 abutting against the bottom of the driving member 110 is relaxed to drive the bearing part 100 to move downward to realize lens focusing.
[0056] By arranging the two groups of symmetric memory alloy wires 300 on the driving member 110, the driving assembly can drive the bearing part 100 to move upward or downward to realize focusing, and the driving direction is more. Meanwhile, the memory alloy wires 300 arranged in opposite directions can also play a role in resetting, so that the bearing part 100 returns to the original position.
[0057] In some specific embodiments of this application, the drive assembly further includes a damping adhesive 500, which is disposed at the intersection of two sets of shape memory alloy wires 300. The damping adhesive 500 is used to reduce friction between the shape memory alloy wires 300.
[0058] For example Figure 9 and Figure 10 As shown, the drive assembly also includes a damping adhesive 500. The damping adhesive 500 is disposed at the intersection of the two sets of shape memory alloy wires 300, so that the two sets of shape memory alloy wires 300 can be separated by the damping adhesive 500 and will not come into contact with each other. This prevents friction from occurring when the shape memory alloy wires 300 contract when energized, causing the two sets of shape memory alloy wires 300 to move relative to each other, thus preventing wear on the shape memory alloy wires 300 and extending their service life.
[0059] In some specific embodiments of this application, each group of shape memory alloy wires 300 is provided with multiple wires, and the multiple shape memory alloy wires 300 in each group jointly drive the drive member 110 to move in the same direction.
[0060] For example Figure 6 , Figure 8 and Figure 10 As shown, each group of shape memory alloy wires 300 contains two shape memory alloy wires 300. These two wires simultaneously drive the drive component 110, doubling the thrust of the drive assembly. It is easy to understand that the number of shape memory alloy wires 300 in each group can be not only two, but also three, four, etc., all of which effectively increase the thrust of the drive assembly.
[0061] In some specific embodiments of this application, the surface of the drive member 110 that abuts against the shape memory alloy wire 300 is arc-shaped.
[0062] For example Figure 3 and Figure 4 As shown, the surface of the drive member 110 that abuts against the shape memory alloy wire 300 is arc-shaped. By setting the surface of the drive member 110 that abuts against the shape memory alloy wire 300 to be arc-shaped, the friction between the shape memory alloy wire 300 and the drive member 110 can be reduced, the wear of the shape memory alloy wire 300 can be reduced, and the service life of the shape memory alloy wire 300 can be extended.
[0063] Furthermore, the lens module also includes a housing 600, as shown in the figure. The housing 600 encompasses the base 200, the support portion 100, and the drive assembly, providing a certain degree of protection for the base 200, the support portion 100, the suspension assembly 400, and the drive assembly. Simultaneously, the shape of the housing 600 matches the shape of the base 200, both being semi-circular and semi-square, reducing volume and space occupation.
[0064] According to the camera device of the second aspect of the present application, the lens module of the first aspect of the present application is adopted, so that the volume of the camera device is reduced, and the horizontal height of the camera device is reduced, thereby facilitating the miniaturization of the camera device.
[0065] According to the camera device of the second aspect of the present application, the lens module of the first aspect of the present application is adopted, so that the volume of the camera device is reduced, and the horizontal height of the camera device is reduced, thereby facilitating the miniaturization of the camera device.
