Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a camera module and electronic equipment. Background Art

[0002] With the continuous advancement of technology, consumers have increasingly higher requirements for the image quality of mobile phone cameras. Consumers also require functions such as optical image stabilization and zoom on mobile phone cameras. For example, periscope cameras use optical components such as prisms to convert external light into a horizontal beam. The horizontal beam is then projected into a horizontally set lens for imaging, which can achieve optical image stabilization and zoom. Periscope cameras can usually adjust the focal length. However, in actual use, when the telephoto lens is not powered on, it can move freely in the direction of the optical path inside the camera module as the whole body moves. During the shaking process, the telephoto lens will hit the inner wall of the camera module housing, making unusual noises and affecting the user experience. Utility Model Content

[0003] The present application provides a camera module and an electronic device, wherein the camera module can reduce the abnormal noise caused by the lens hitting the inner wall of the camera module housing during shaking.

[0004] An embodiment of the present application provides a camera module, which includes a base, an anti-shake assembly, a lens assembly and a protective part. The base includes a first groove and a second groove, the first groove and the second groove are connected, the anti-shake assembly is accommodated in the first groove, the lens assembly includes a lens carrier, the second groove includes a first wall surface and a second wall surface, the first wall surface and the second wall surface are spaced relative to each other along the optical axis direction of the lens assembly.

[0005] The protective member is made of elastic material, and includes a main body and a protective protrusion protruding from the surface of the main body, the protective protrusion has an arc-shaped protective surface, the protective member is connected to the first wall surface and the second wall surface, along the optical axis direction of the lens assembly, the protective member on the first wall surface and the protective member on the second wall surface are spaced opposite to each other, the lens assembly is accommodated in the second groove, the lens carrier is located between the protective member on the first wall surface and the protective member on the second wall surface, the arc-shaped protective surfaces of the protective protrusions of the protective member are all facing the end face of the lens carrier, and are spaced opposite to the end face; the lens assembly can move between the first wall surface and the second wall surface along the optical axis direction, and the arc-shaped protective surface of the protective protrusion can elastically abut the end face of the lens carrier.

[0006] In this embodiment, the protective part is made of elastic material and is provided with a protective protrusion. The electronic device uses the camera module of this embodiment. When the camera module is not powered on, as the electronic device moves as a whole, the lens module of the camera module can swing freely in the direction of the optical path, and in the process of swinging, it will move toward the first wall and the second wall of the second groove. The arc-shaped protective surface of the protective protrusion will abut the end face of the lens carrier to prevent the lens carrier from directly colliding with the first wall and the second wall, thereby buffering the impact force between the lens module and the base and reducing abnormal noise inside the camera module. Moreover, the protective surface of the protective protrusion in this embodiment is in point and surface contact with the end face of the lens carrier, which can reduce the contact area and achieve isolated impact, and can further reduce the abnormal noise inside the camera module.

[0007] In one embodiment, there are multiple protective protrusions, and the multiple protective protrusions are arranged in an array; the protective surface of the protective protrusion is in point-to-surface contact with the end face of the lens carrier; the point array formed by the multiple protective protrusions abuts the end face, which reduces the contact area and reduces the abnormal noise caused by impact compared to the contact between planes.

[0008] In one embodiment, the protective protrusion is spherical. The spherical protrusion has a curved surface and is sufficiently elastic to provide good elastic buffering when impacted by the lens assembly; compared to contact with a spring or a flat plate, it further reduces abnormal noise.

[0009] In one embodiment, the protective protrusion is hemispherical, with a diameter less than or equal to the width of the body, and the width of the body being perpendicular to the optical axis of the lens assembly. This embodiment, through a single point of contact with the carrier end surface, has a simple structure and also achieves the function of reducing abnormal noise.

[0010] In one embodiment, there are four protective members. Two partitions are provided on the base, with a gap formed between the two partitions. The optical axis of the lens assembly passes through the gap. The surfaces of the two partitions form the first wall of the second groove. Each partition is connected to a protective member. The second wall is spaced apart and opposed to the partitions, and two protective members are provided on the second wall. In this embodiment, the four protective members are divided into two groups and located on the two end faces of the lens carrier. In fact, there is a protective member on each side of each end face. This ensures the stability of the lens carrier during impact and prevents the lens assembly from shifting after the impact.

The drive unit is connected to the anti-shake carrier and the first mounting groove, and the drive unit is capable of driving the anti-shake carrier to move. The anti-shake carrier slides relative to the first slide groove via the first sliding unit. In this embodiment, the anti-shake assembly can move relative to the lens assembly after being driven by the drive unit to achieve anti-shake.

[0012] In one embodiment, the lens assembly further comprises a lens group, a drive unit, and a second sliding unit. The lens is assembled to the lens carrier, and the base further comprises a second slide groove and a second mounting groove. The second slide groove is recessed in the bottom wall of the second groove, and the second mounting groove is recessed in the side wall of the second groove.

The drive unit of the lens assembly is connected to the lens carrier and the second mounting groove, and the drive unit of the lens assembly is capable of driving the lens carrier to move along the optical axis of the lens assembly. The lens carrier slides relative to the second slide groove via the second sliding unit. In this embodiment, the lens group is a periscope lens, which is driven to move by the drive unit.

[0013] In one embodiment, the first sliding portion includes a first groove and a ball provided on the anti-shake carrier, and the ball of the first sliding portion is located in the first groove and the first sliding groove;

[0014] The second sliding portion includes a second groove and a ball provided on the lens carrier, and the ball of the second sliding portion is located in the second groove and the second sliding slot.

[0040] Please also refer to Figure 8 and Figure 9 , Figure 8 for Figure 4 The schematic diagram of the structure of the protective member shown in FIG. Figure 9 for Figure 8 The schematic plan view of the protective member shown. The protective member 20 is made of an elastic material such as rubber. The protective member 20 includes a main body 21 and a protective protrusion 22. The main body 21 is a rectangular sheet, and the protective protrusion 22 is protruded from the surface of the main body 21. The protective protrusion 22 is a spherical, hemispherical or arc-shaped protrusion, and the protective protrusion 22 is integrally formed with the main body 21. The protective protrusion 22 includes an arc-shaped protective surface 221, and the arc-shaped protective surface 221 faces away from the main body 21. The protective protrusion 22 has elastic deformation capability, and the protective protrusion 22 has a certain flexibility. For example, the protective protrusion 22 made of rubber is flexible and not too hard.

[0041] In one embodiment, there are multiple protective protrusions 22, and the multiple protective protrusions 22 are arranged in an array. For example, along the length of the body 21, there are multiple rows of protective protrusions 22, each row having at least two protective protrusions 22; along the width of the body 21, there are at least two columns of protective protrusions 22, each column having multiple protective protrusions 22; along the length of the base 10, that is, along the optical axis of the lens assembly 40.

The window 81 is opposite the prism 32 of the anti-shake assembly 30. Light passes through the window 81 and enters the prism 32 before entering the lens assembly 42. The housing 70 is mounted on the outside of the base 10, securing the cover plate 80 and the base 10 and covering the circuit board 60 and the chip 50. The camera module 100 is used in electronic devices such as mobile phones. During movement, the lens assembly will shake along the optical axis. The two end surfaces 415 of the lens carrier 41 will contact the protective surface 221 of the protective protrusion 22 of the protective member 20, forming a point-to-surface contact. The protective protrusion 22 has a certain degree of elasticity, which can cushion the impact force of the base 10 on the lens assembly 40 and reduce the abnormal sound caused by the impact of the camera module 100. In existing camera modules, the impact surface between the lens and the base 10 is flat, and the large contact area can cause damage to the lens. The protective member 20 of the present application utilizes multiple protective protrusions 22 with curved surfaces to contact the lens carrier 41, forming a point array and surface contact. This not only ensures the impact support range, but also minimizes the effective impact area due to the point-shaped protective protrusions 22, effectively reducing the abnormal sound after the lens assembly 40 impacts the base 10. Furthermore, the stability of the lens carrier 41 after the impact is maintained, reducing the chance of damage and displacement of the lens assembly 40.
