[0035] As people's living standards continue to improve, more and more people are starting to use cameras. The lens assembly is the core component of a camera, and it directly determines the quality of the image. When using a camera, it is necessary to adjust the focal length of the lens assembly to capture a clear image.

[0036] Traditional lens assemblies typically require manual rotation of the lens for focusing, which is inconvenient to use.

[0037] To address the aforementioned problems, in a first aspect, the present invention provides a lens assembly.

[0038] Please see Figures 1-7 , Figure 1 This is a structural schematic diagram of the lens assembly of the present invention from a first-view perspective. Figure 2 This is a schematic diagram of the lens assembly of the present invention from a second perspective. Figure 3 For example Figure 1 The diagram shows a partial structural diagram of the lens assembly.

Figure 6 This is a schematic diagram of the lens assembly of the present invention from a fourth perspective. Figure 7 For example Figure 6 The image shows a cross-sectional view of the lens assembly along the BB direction.

[0039] The lens assembly of the present invention includes a housing 100, a drive module 400, an elastic element 500, a first lens module, and a second lens module. The housing 100 has a receiving cavity, within which the drive module 400, the elastic element 500, the first lens module, and the second lens module are all located. The two ends of the elastic element 500 are respectively connected to the housing 100 and the first lens module. The drive module 400 can press against or release the first lens module. When the drive module 400 presses against the first lens module, it can drive the first lens module to move along a predetermined direction, thereby causing the first lens module to move closer to or further away from the second lens module and causing the elastic element 500 to change from a first working state to a second working state. When the drive module 400 releases the first lens module, the elastic element 500 changes from the second working state to the first working state, and the elastic element 500 can drive the first lens module to move in the opposite direction along the predetermined direction, thereby causing the first lens module to move further away from or closer to the second lens module.

[0040] The lens assembly described above includes a housing 100, a drive module 400, an elastic element 500, a first lens module, and a second lens module. The housing 100 has a receiving cavity, within which the drive module 400, elastic element 500, first lens module, and second lens module are all located. The two ends of the elastic element 500 are connected to the housing 100 and the first lens module, respectively. The drive module 400 can press against or release the first lens module. When the drive module 400 presses against the first lens module, it can move the first lens module along a predetermined direction, thereby causing the first lens module to move closer to or further away from the second lens module and causing the elastic element 500 to change from a first working state to a second working state. When the drive module 400 releases the first lens module, the elastic element 500 changes from the second working state back to the first working state, and the elastic element 500 can move the first lens module in the opposite direction along the predetermined direction, thereby causing the first lens module to move further away from or closer to the second lens module. In this solution, when the drive module 400 presses against the first lens module, it can drive the first lens module to move along a predetermined direction, thereby causing the first lens module to move closer to or away from the second lens module and causing the elastic element 500 to change from a first working state to a second working state; when the drive module 400 releases the first lens module, the elastic element 500 changes from the second working state to the first working state, and the elastic element 500 can drive the first lens module to move in the opposite direction along the predetermined direction, thereby causing the first lens module to move away from or closer to the second lens module. No manual adjustment is required for focusing, making it more convenient to use.

[0041] Traditional lens assemblies typically require manual focusing by rotating the lens, which is inconvenient. In this solution, when the drive module presses against the first lens module, it moves the first lens module along a predetermined direction, bringing it closer to the second lens module and causing the elastic element to change from a first working state to a second working state. When the drive module releases the first lens module, the elastic element changes from the second working state back to the first working state, and the elastic element can move the first lens module in the opposite direction along the predetermined direction, moving it away from the second lens module. This eliminates the need for manual focusing and makes the solution more convenient to use.

[0042] The first working state of the elastic element 500 is a state in which the elastic element 500 neither stretches nor compresses, and the second working state of the elastic element 500 is a state in which the elastic element 500 stretches or compresses.

[0075] In a second aspect, the present invention provides a camera including the lens assembly 10000 as described above.

[0076] The camera described above employs a lens assembly 10000 comprising a housing 100, a drive module 400, an elastic element 500, a first lens module, and a second lens module. The housing 100 has a receiving cavity, within which the drive module 400, elastic element 500, first lens module, and second lens module are all located. The two ends of the elastic element 500 are connected to the housing 100 and the first lens module, respectively. The drive module 400 can press against or release the first lens module. When the drive module 400 presses against the first lens module, it can move the first lens module along a predetermined direction, thereby causing the first lens module to move closer to or further away from the second lens module and causing the elastic element 500 to change from a first working state to a second working state. When the drive module 400 releases the first lens module, the elastic element 500 changes from the second working state to the first working state, and the elastic element 500 can move the first lens module in the opposite direction along the predetermined direction, thereby causing the first lens module to move further away from or closer to the second lens module. In this solution, when the drive module 400 presses against the first lens module, it can drive the first lens module to move along a predetermined direction, thereby causing the first lens module to move closer to or away from the second lens module and causing the elastic element 500 to change from a first working state to a second working state; when the drive module 400 releases the first lens module, the elastic element 500 changes from the second working state to the first working state, and the elastic element 500 can drive the first lens module to move in the opposite direction along the predetermined direction, thereby causing the first lens module to move away from or closer to the second lens module. No manual adjustment is required for focusing, making it more convenient to use.

[0077] Traditional lens assemblies typically require manual focusing by rotating the lens, which is inconvenient. In this solution, when the drive module presses against the first lens module, it moves the first lens module along a predetermined direction, causing it to move closer to or away from the second lens module and changing the elastic element from a first working state to a second working state. When the drive module releases the first lens module, the elastic element changes from the second working state back to the first working state, and the elastic element can move the first lens module in the opposite direction along the predetermined direction, causing it to move closer to or away from the second lens module. This eliminates the need for manual focusing and makes the solution more convenient to use.

[0078] The specific workflow is as follows: The camera body sends a signal, and information is transmitted between the camera contacts and the lens assembly 10000. This controls the drive unit 410 mounted on the plastic main barrel 200. The drive unit 410 is a focusing motor. The focusing motor drives the first lens barrel 300 to move downwards, and the elastic element 500 will exert an upward pulling force on the first lens barrel 300. In this way, the position of the first lens barrel 300 can be controlled by the drive unit 410, i.e., the focusing motor, until the most precise focus position of the subject is found. Then, the shutter can be controlled to capture the image.

[0079] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
