[0035] Reference below Figures 1 to 10 To describe the lens module according to an embodiment of the present application.

[0036] For example Figure 2 and Figure 3 As shown, the lens module according to the embodiment of the present application includes a carrying part 100, a base 200, a driving assembly and a position sensor. The main body of the carrying part 100 is annular, and the carrying part 100 is used to carry the lens; the base 200 includes a main body 210 and a fixing part 220. The main body 210 is annular, and a accommodating cavity matching the carrying part 100 is opened in the main body 210, and the carrying part 100 is arranged in the accommodating cavity; a notch is opened on the side of the main body 210, and the fixing part 220 is arranged on the side of the notch and fixedly connected to the main body 210; a driving member 110 is provided on the carrying part 100, and the driving member 110 protrudes from the notch; the driving assembly is fixedly arranged on the fixing part 220, and the driving assembly drives the carrying part 100 to move in the accommodating cavity by driving the driving member 110; the position sensor is used to sense the positional relationship between the carrying part 100 and the base 200.

[0037] For example Figure 2 and Figure 3 As shown, the bearing part 100 is annular and has an annular cavity inside. The annular cavity is used to bear a circular lens. The shape of the bearing part 100 is annular, which can reduce unnecessary volume and retain only the necessary parts. The base 200 includes a main body 210 and a fixing part 220. The main body 210 is annular and has an accommodating cavity matching the bearing part 100, which frames the bearing part 100. A notch is provided on the side of the main body 210, and the fixing part 220 is arranged on the side of the notch and fixedly connected to the main body 210; a driving member 110 is provided on the bearing part 100, and the driving member 110 protrudes from the notch; the driving assembly is fixedly arranged on the fixing part 220, and the driving assembly drives the bearing part 100 to move in the accommodating cavity by driving the driving member 110. The position sensor can be used to sense the relationship between the supporting part 100 and the base 200, so that the driving component can sense whether the supporting part 100 is adjusted into place or over-adjusted according to the position sensor, which facilitates the driving component to adjust the error and can adjust the supporting part 100 to the accurate position, thereby improving the accuracy of lens focusing.

[0038] By providing a notch and a driving member 110, the driving member 110 is protruded from the notch of the base 200 and is driven by the driving assembly, thereby reducing the volume and weight of the lens module to the greatest extent. The base 200 is semicircular and semi-square as a whole, and a driving assembly is provided on one side of the square. The semicircular shape is mainly used to frame the bearing part 100 therein, and the semi-square part can not only frame the bearing part 100 therein but also install the driving assembly on the fixed part 220, so that the driving assembly can drive the bearing part 100 to move and thus realize the function of lens focusing. Furthermore, the main body 210 and the fixed part 220 of the base 200 are made as one piece. The position sensor can be formed in a variety of ways, such as a magnet combined with a Hall sensor or a magnet combined with a TMR sensor. The position sensor senses the distance and position between the movable part of the bearing part 100 and the fixed part to understand whether the bearing part 100 is accurately in place, which facilitates the driving assembly to adjust the position of the bearing part 100.

[0039] The lens module according to the embodiment of the present application, through such a configuration, can achieve at least the following beneficial effects: reducing the volume of the lens module. Simultaneously, the drive assembly is arranged on the side of the base 200 rather than on the top or bottom, which can reduce the height of the lens module and the space occupied by the lens module, thereby facilitating the miniaturization of the camera device. The position sensor can sense whether the support portion 100 is adjusted in place or overadjusted, facilitating the drive assembly to adjust errors, enabling the support portion 100 to be adjusted to the correct position, and improving the accuracy of lens focus.

[0040] In some specific embodiments of the present application, the position sensor includes a magnetic part 510 and a magnetic sensing part 520. Any one of the magnetic part 510 or the magnetic sensing part 520 is provided on the carrying part 100, and the other of the magnetic part 510 and the magnetic sensing part 520 is fixedly arranged; the position sensor senses the position relationship between the carrying part 100 and the base 200 by sensing the position of the magnetic part 510 through the magnetic sensing part 520.

[0041] For example Figure 3 and Figure 4As shown, the position sensor includes a magnetic member 510 and a magnetic sensing member 520. The magnetic member 510 is disposed on the carrier 100. The magnetic sensing member 520 is fixed relative to the magnetic member 510. Alternatively, the magnetic sensing member 520 is connected to the carrier 100, and the magnetic member 510 is fixed relative to the magnetic sensing member 520. One of the magnetic sensing member 520 and the magnetic member 510 is fixed, while the other moves with the carrier 100. The two are arranged relative to each other so that the magnetic flux generated by the magnetic member 510 can pass through the magnetic sensing member 520. The magnetic sensing member 520 obtains the positional relationship between itself and the magnetic member 510 by sensing the change in the magnetic flux of the magnetic member 510 passing through the magnetic sensing member 520. The magnetic sensing member 520 can be configured in various ways, such as a Hall sensor or a TMR sensor. When a Hall sensor is used, there is a Hall voltage inside the Hall sensor. The Hall voltage is affected by the magnetic field strength. The stronger the magnetic field, the higher the Hall voltage. It is easy to understand that the closer the distance between the magnetic part 510 and the Hall sensor, the stronger the magnetic field strength received by the Hall sensor, and the higher the Hall voltage. Therefore, the position of the carrier part 100 can be sensed by the setting of the Hall sensor and the magnetic part 510, thereby facilitating the driving component to adjust the position of the carrier part 100, making the driving component's control over the carrier part 100 more precise and making the lens focusing accuracy higher.

[0042] In some specific embodiments of the present application, the magnetic component 510 is disposed at an end surface of the driving component 110 , and the magnetic sensing component 520 is disposed opposite to the magnetic component 510 .

[0043] For example Figure 3 and Figure 5 As shown, the magnetic member 510 is arranged at the end surface of the driving member 110, and the magnetic sensing member 520 is arranged relative to the magnetic member 510. The magnetic sensing member 520 is fixed relative to the magnetic member 510 and can be fixed together with the housing 600, for example Figure 1 As shown, the lens module also includes a housing 600, which encloses the base 200, the carrier 100, and the drive assembly, providing some protection for the base 200, the carrier 100, and the drive assembly. The housing 600 is divided into two parts, upper and lower, for ease of assembly. The shape of the housing 600 matches that of the base 200, both being semi-circular and semi-square, reducing its size and space requirements.

[0044] A circle of annular protrusions is provided on the inner side of the lower half of the shell 600, and the height of the annular protrusions is relatively low. A circle of annular protrusions is provided on the outer side of the upper half of the shell 600. The upper and lower parts are combined to form an annular groove to contain the supporting part 100 and the base 200, preventing the lens assembly from moving in the horizontal direction. At the same time, since the height of the annular protrusions on the inner side is relatively low, the supporting part 100 can still be used to install the lens, and some space is reserved for the movement of the lens.

[0045] The magnetic sensing component 520 is fixedly connected to the shell 600, and the base 200 is fixedly connected to the shell 600, so the magnetic sensing component 520 is fixed relative to the base 200. When the driving component drives the bearing part 100 to move, the magnetic sensing component 520 can sense the position of the bearing part 100 by sensing the position of the magnetic component 510, thereby facilitating the driving component to adjust the position of the bearing part 100.

[0046] In some specific embodiments of the present application, a first groove 111 is defined at an end surface of the driving member 110 , and the magnetic member 510 is embedded in the first groove 111 .

[0047] For example Figure 3 and Figure 5 As shown, a first groove 111 is formed at the end surface of the driving member 110, and the magnetic member 510 is embedded in the first groove 111. By forming the first groove 111 at the end surface of the driving member 110, the magnetic member 510 is embedded in the first groove 111, which can save space and facilitate miniaturization of the lens module.

[0048] In some specific embodiments of the present application, the driving component includes a memory alloy wire 300, and the fixing portion 220 is arranged on both sides of the gap; the two ends of the memory alloy wire 300 are respectively fixed on the fixing portion 220, and the middle part of the memory alloy wire 300 is hooked on the driving member 110; the driving component drives the driving member 110 to move by energizing the memory alloy wire 300 to contract.

[0049] For example Figure 5 As shown, the driving component is a memory alloy wire 300. The fixing portion 220 is set on both sides of the notch. The memory alloy wire 300 is set in a V shape, with both ends fixed on the fixing portion 220, and the middle portion is in contact with the driving member 110 and hooked on the driving member 110. When the memory alloy wire 300 is energized and contracted, it can drive the driving member 110 to move. The movement of the driving member 110 drives the bearing portion 100 to move together, so that the lens can move to achieve the focusing effect. The memory alloy wire 300 can be set on the top of the driving member 110, for example Figure 5 and Figure 6 As shown, it can also be set at the bottom of the driving member 110, for example Figure 7 and Figure 8As shown, memory alloy wires 300 may also be provided on both the top and bottom of the driving member 110, for example Figure 9 and Figure 10 When the memory alloy wire 300 is disposed on the top of the driver 110, the memory alloy wire 300 contracts when energized to drive the driver 110 downward. When the memory alloy wire 300 is disposed on the bottom of the driver 110, the memory alloy wire 300 contracts when energized to drive the driver 110 upward.

[0050] Furthermore, a terminal 310 is provided on the fixing portion 220. The terminal 310 is made of a metal sheet. The end of the memory alloy wire 300 is fixedly connected to the terminal 310. The terminal 310 supplies power to the memory alloy wire 300 so that the memory alloy wire 300 can be energized and contracted to generate a driving force.

[0051] The memory alloy wire 300 is used for driving. The memory alloy wire 300 has a smaller volume and a greater driving force, can better drive the bearing part 100, and can reduce the volume of the driving component, which is conducive to the miniaturization of the lens module.

[0052] In some specific embodiments of the present application, two groups of memory alloy wires 300 are provided, the middle portion of one group of memory alloy wires 300 abuts against the top of the driving member 110 and its two ends are located at the bottom of the fixed portion 220; the middle portion of the other group of memory alloy wires 300 abuts against the bottom of the driving member 110 and its two ends are located at the top of the fixed portion 220.

[0053] For example Figure 9 and Figure 10 As shown, two groups of memory alloy wires 300 are provided. The middle part of one group of memory alloy wires 300 abuts the top of the driver 110 and its two ends are located at the bottom of the fixed portion 220; the middle part of the other group of memory alloy wires 300 abuts the bottom of the driver 110 and its two ends are located at the top of the fixed portion 220. Memory alloy wires 300 are provided at both the top and bottom of the driver 110, so that the driver 110 can be driven upward or downward by the driving assembly. When the memory alloy wire 300 is set at the top of the driver 110, the memory alloy wire 300 can be energized and contracted to drive the driver 110 downward. When the memory alloy wire 300 is set at the bottom of the driver 110, the memory alloy wire 300 can be energized and contracted to drive the driver 110 upward. Through such a configuration, the driving assembly can drive the bearing portion 100 to move in more directions, and can be driven upward or downward, making the drive more flexible.

[0054] Furthermore, the contact surface between the driving member 110 and the memory alloy wire 300 is in an arc shape, for example Figure 2 and Figure 3By setting the contact surface of the driving member 110 and the memory alloy wire 300 to be arc-shaped, the friction between the memory alloy wire 300 and the driving member 110 can be reduced, the wear of the memory alloy wire 300 can be reduced, and the service life of the memory alloy wire 300 can be extended.

[0055] In some specific embodiments of the present application, each group of memory alloy wires 300 is provided with a plurality of memory alloy wires 300 , and the plurality of memory alloy wires 300 jointly drive the driving member 110 to move along the same driving direction.

[0056] For example Figure 6 、 Figure 8 and Figure 10 As shown, each group of memory alloy wires 300 is provided with two, and the two memory alloy wires 300 drive the driving member 110 to move along the same driving direction. Multiple memory alloy wires driving along the same driving direction have greater thrust, thereby doubling the thrust of the driving assembly. It is easy to understand that the number of memory alloy wires 300 in each group can be set not only to two, but also to three, four, etc., which can effectively increase the thrust of the driving assembly.

[0057] In some specific embodiments of the present application, a suspension component 400 is further included. The suspension component 400 connects the base 200 and the carrying part 100 , and the carrying part 100 is suspended in the accommodating cavity through the suspension component 400 .

[0058] For example Figure 2 and Figure 3 As shown, the lens module also includes a suspension assembly 400. The suspension assembly 400 connects the base 200 and the carrier 100, allowing the carrier 100 to suspend in the accommodating cavity of the base 200, making it easy for the drive assembly to drive the carrier 100 to move and achieve focusing. Furthermore, the suspension assembly 400 has a certain degree of elasticity, which allows the carrier 100 to return to its original position after the drive assembly drives the carrier 100.

[0059] In some specific embodiments of the present application, the suspension assembly 400 includes a suspension portion 410 and a connecting portion 420, the suspension portion 410 is connected to the bearing portion 100, the connecting portion 420 is fixedly arranged on the base 200 and elastically connected to the suspension portion 410, and the bearing portion 100 is suspended in the accommodating cavity through the suspension portion 410 and the connecting portion 420.

[0060] For example Figure 3 and Figure 4As shown, the suspension assembly 400 includes a suspension portion 410 and a connecting portion 420. The suspension portion 410 is annular and matches the shape of the bearing seat. The suspension portion 410 is connected to the top and bottom surfaces of the bearing portion 100. The connecting portion 420 connects the suspension portion 410 and the base 200, so that the bearing portion 100 can be suspended in the accommodating cavity through the suspension portion 410 and the connecting portion 420, so that the driving assembly can easily drive the bearing portion 100.

[0061] The annular suspension portion 410 connects to the top and bottom surfaces of the support portion 100, creating a larger connection area between the suspension portion 410 and the support portion 100 and ensuring a more stable connection. The connecting portion 420 connects the end of the suspension portion 410 closest to the drive assembly with the fixed portion 220 of the base 200, suspending the support portion 100 within the accommodating cavity of the base 200. The connecting portion 420 is arranged on the fixed portion 220 in the shape of an airplane wing, providing a larger connection area and a more stable connection.

[0062] Furthermore, the top and bottom surfaces of the support portion 100 are both provided with suspension assemblies 400. This allows the support portion 100 to be better suspended within the accommodating cavity of the base 200, making it easier for the drive assembly to drive the support portion 100. Furthermore, the connection portion 420 is elastically configured, allowing the support portion 100 to return to its original position due to the elasticity of the connection portion 420 when the driving force of the drive assembly disappears.

[0063] In some specific embodiments of the present application, the suspension assembly 400 further includes a limiting portion 430 . A second groove 211 is defined on a side of the main body 210 , and the limiting portion 430 protrudes into the second groove 211 .

[0064] For example Figure 3 and Figure 4 As shown, the suspension assembly 400 further includes a limiting portion 430. A second groove 211 is defined on the side of the main body 210, and the limiting portion 430 protrudes and fits into the second groove 211. The arrangement of the limiting portion 430 and the second groove 211 prevents the support portion 100 from shaking or moving, and allows it to be stably suspended in the receiving cavity of the base 200.

[0065] The limiting portion 430 is arranged on the suspension portion 410 of the suspension component 400, and is symmetrically arranged on both sides of the suspension portion 410. The second groove 211 is also symmetrically arranged on both sides of the main body 210. The limiting portion 430 is embedded in the second groove 211 so that the horizontal position of the suspension portion 410 of the suspension component 400 can be fixed, and at the same time, the movement in the vertical direction is not affected, and it can move up and down under the drive of the driving component to achieve focusing.
