Description

Technical Field

[0001] This application relates to the field of camera device technology, and more particularly to a lens structure and electronic device. Background Technology

[0002] High-resolution lenses are increasingly favored by consumers due to their superior image quality, and continuously increasing the image sensor's image plane size has gradually become one of the mainstream research directions in this field. To accommodate the large image sensor size, the diameter of the lens elements adjacent to the image sensor is also increasing; simultaneously, to reduce the lens's impact on the appearance of electronic devices, the lens head size is becoming smaller and smaller, thus giving rise to small-head, large-image-plane lenses.

[0003] In related technologies, small-head, large-image-plane lenses typically have two adjacent lenses with a significant diameter difference. When there is a large diameter difference between adjacent lenses, a spacer is usually used for transition. The lens barrel has an auxiliary support surface formed at the position of the spacer along its axial direction. The spacer and the auxiliary support surface of the lens barrel need to maintain a small axial gap (e.g., less than 7 micrometers), or even zero axial gap, to ensure the structural stability of the spacer.

[0004] However, due to unavoidable processing errors, and the greater the number of lenses, the greater the accumulated dimensional error of the lenses along the lens barrel axis. This makes it more difficult to keep the axial gap between the spacers and the auxiliary bearing surfaces within the preset range. Especially when there are two or more auxiliary bearing surfaces in the lens barrel, coupled with the accumulated dimensional error of multiple spacers along the lens barrel axis, it is even more difficult to ensure that the axial gap between all spacers and auxiliary bearing surfaces is less than the preset value. This will lead to a decrease in the structural stability of the spacers, which in turn will affect the support effect of the spacers on lenses with larger diameters, affect the structural stability of the lenses, and reduce the yield of the lens. Utility Model Content

[0005] This application discloses a lens structure and electronic device that can compensate for the dimensional processing error and assembly error of the lens, provide more stable axial auxiliary support for lenses with larger diameters, reduce the overturning moment acting on larger lenses, and thus help improve the structural stability of the lens and increase the yield of the lens structure.

[0006] To achieve the above objectives, in a first aspect, this application discloses a lens structure, the lens structure comprising:

[0007] Lens tube;

[0008] A plurality of lenses are arranged along the axial direction of the lens barrel within the lens barrel. The plurality of lenses include adjacent first and second lenses, wherein the radial dimension of the first lens is smaller than the radial dimension of the second lens, and an accommodating space is formed between the first lens, the second lens, and the lens barrel; and...

[0009] An elastic spacer is disposed in the accommodating space, in the axial direction of the lens barrel, the elastic spacer abuts between the second lens and the lens barrel, and in the axial direction of the lens barrel, the elastic spacer has a deformation space for allowing the elastic spacer to deform in the axial direction of the lens barrel.

[0010] In the lens structure provided in this application embodiment, by setting an elastic spacer and having the elastic spacer abut against the second lens and the lens barrel in the axial direction of the lens barrel, the second lens can be supported by the elastic spacer. Moreover, the elastic spacer has a deformation space, which provides space for the deformation of the elastic spacer, allowing or facilitating the deformation of the elastic spacer to compensate for the dimensional processing errors and assembly errors of the lens. This ensures that the elastic spacer can always maintain close contact with the lens barrel and the second lens in the axial direction of the lens barrel, avoiding the second lens being suspended. This provides a more stable axial auxiliary support for the second lens, reduces the overturning moment acting on the second lens, and thus helps to improve the structural stability of the second lens and increase the yield of the lens structure.

[0011] As an optional implementation, in an embodiment of the first aspect of this application, the projection of the first lens onto the second lens is a first projection, and the projection of the elastic spacer onto the second lens is a second projection, wherein the first projection and the second projection do not overlap.

[0012] In other words, the first projection and the second projection do not coincide; they are either spaced apart or tangentially positioned. This arrangement means that the first lens and the elastic spacer do not overlap or intersect along the axial direction of the lens barrel, and they do not abut against each other. Compared to a spacer that partially abuts against the first and second lenses, this reduces the force exerted by the second lens on the first lens through the spacer. The spacer can better distribute the force from the second lens to the first lens, thus reducing the stress on the first lens. This helps to lower the risk of cracks or fissures caused by excessive stress on the first lens, ensuring its lifespan and optical performance.

[0013] As an optional implementation, in an embodiment of the first aspect of this application, the deformation space extends through the side of the elastic spacer in the radial direction of the lens barrel.

[0014] The elastic spacer adopts the above-described structure. The sidewall of the elastic spacer that abuts against the second lens is equivalent to an elastic arm with one end as the connecting end and the other end as the free end. The free end of the elastic arm is suspended. When the elastic arm is squeezed by the second lens, it can deform more easily, buffering the force on the second lens to protect it. At the same time, it can generate a larger deformation. Therefore, even if the lens has dimensional processing errors and assembly errors, corresponding error compensation can be performed to ensure that the elastic spacer can always maintain close contact with the lens barrel and the second lens in the axial direction of the lens barrel. This provides a more stable axial auxiliary support for the second lens, reduces the overturning moment acting on the second lens, and thus helps to improve the structural stability of the second lens and increase the yield of the lens structure.

[0015] In addition, the opening direction of the elastic spacer extends radially along the lens barrel. Compared with the way the opening direction of the elastic spacer extends axially along the lens barrel, it can ensure that the elastic spacer has a larger contact area with the second lens and the lens barrel in the axial direction of the lens barrel. This can provide more stable axial auxiliary support for the second lens, which is conducive to further improving the structural stability of the second lens and further improving the yield of the lens structure.

[0016] As an optional implementation, in an embodiment of the first aspect of this application, the lens structure has an optical axis, and the deformation space passes through the side of the elastic spacer facing away from the optical axis, so that the edge of the elastic spacer away from the optical axis has a free end.

[0017] Since the stress points of each lens are mainly located at the edges of the lens far from the optical axis, the second lens's edge far from the optical axis mainly compresses the elastic spacer's edge far from the optical axis. By setting the opening of the elastic spacer to face away from the optical axis, i.e., the opening is formed on the outer peripheral surface of the elastic spacer far from the optical axis, the stress point of the second lens acting on the elastic spacer can be close to or located at the free end of the elastic spacer. This allows the elastic spacer to deform more easily when subjected to the compression of the second lens, buffering the force on the second lens to protect it. At the same time, it can generate a larger deformation. Thus, even if the lens has dimensional processing errors and assembly errors, corresponding error compensation can be performed to ensure that the elastic spacer can always maintain close contact with the lens barrel and the second lens in the axial direction of the lens barrel. This provides more stable axial auxiliary support for the second lens, reduces the overturning moment acting on the second lens, and thus helps to improve the structural stability of the second lens and increase the yield of the lens structure.

[0018] As an optional implementation, in an embodiment of the first aspect of this application, in the orthographic projection with the axial direction of the lens barrel, the orthographic projection of the contact area between the second lens and the elastic spacer falls within the orthographic projection range of the deformation space. This allows the force point of the second lens acting on the elastic spacer to correspond to the deformation space, thereby making it easier for the elastic spacer to deform when subjected to the compression of the second lens, buffering the force on the second lens and protecting it.

[0019] As an optional implementation, in an embodiment of the first aspect of this application, the lens structure has an optical axis, and the elastic spacer includes:

[0020] A first portion, extending axially along the lens barrel and abutting against the lens barrel in the axial direction; and,

[0021] A second portion is connected at an angle to the first portion, forming the deformation space between the second portion and the first portion. The second portion extends away from the optical axis and abuts against the second lens in the axial direction of the lens barrel, and is spaced apart from the lens barrel.

[0022] In the above scheme, the second part is mainly deformed by the action of the second lens. The second part is equivalent to an elastic arm with one end as the connecting end and the other end as the free end. The free end is suspended. When the second part is squeezed by the second lens, the second part can deform more easily, buffering the force on the second lens to protect it. At the same time, it can generate a larger deformation. Therefore, even if the lens has dimensional processing errors and assembly errors, corresponding error compensation can be performed to ensure that the elastic spacer can always maintain close contact with the lens barrel and the second lens in the axial direction of the lens barrel. This can provide more stable axial auxiliary support for the second lens, reduce the overturning moment acting on the second lens, and thus help improve the structural stability of the second lens and increase the yield of the lens structure.

[0023] As an optional implementation, in an embodiment of the first aspect of this application, a groove is provided at the connection between the first part and the second part, the groove opening direction extends radially along the lens barrel, and the groove opening is oriented towards the lens barrel.

[0024] This configuration allows the first and second parts to work together as the elastic arm of the elastic spacer, increasing the arm length of the elastic spacer. This makes it easier for the second part to deform when subjected to the pressure of the second lens, buffering the force on the second lens and protecting it. It also generates a larger forming variable, thus allowing for compensation even if the lens has dimensional processing errors or assembly errors. This ensures that the elastic spacer maintains close contact with the lens barrel and the second lens along the lens barrel axis, providing more stable axial support for the second lens, reducing the overturning moment acting on the second lens, and ultimately improving the structural stability of the second lens and increasing the yield rate of the lens structure.

[0025] As an optional implementation, in an embodiment of the first aspect of this application, the inner wall surface of the lens barrel is formed with a first step surface and a second step surface arranged at intervals along the axial direction of the lens barrel. The first step surface and the second step surface are connected by a connecting surface. In the axial direction of the lens barrel, the second step surface is closer to the second lens than the first step surface. The accommodating space is formed between the first step surface, the connecting surface, the second step surface, the first lens, and the second lens.

[0026] Along the axial direction of the lens barrel, the first portion abuts against the first stepped surface, and the second portion is spaced apart from the second stepped surface.

[0027] In the above design structure, since the second step surface is closer to the second lens than the first step surface in the axial direction of the lens barrel, the distance between the second step surface and the second part in the axial direction of the lens barrel is smaller than the distance between the first step surface and the second part. Therefore, when the second part deforms to a certain extent, the second step surface abuts against the second part to prevent the second part from continuing to deform, avoid excessive deformation of the second part, and thus avoid irreversible deformation of the second part, which would lead to elastic failure and affect its use.

[0028] As an optional implementation, in the embodiment of the first aspect of this application, in the radial direction of the lens barrel, the first part abuts between the first lens and the connecting surface. That is, the first part abuts both the first lens and the connecting surface. Thus, the cooperation between the first lens and the connecting surface can limit the first part in the radial direction of the lens barrel, preventing the elastic spacer from moving randomly and causing the position of the elastic spacer to deviate. This ensures that the elastic spacer can always maintain close contact with the lens barrel and the second lens in the axial direction of the lens barrel, providing a more stable axial auxiliary support for the second lens, thereby improving the structural stability of the second lens and increasing the yield of the lens structure.

[0029] And / or, the plurality of lenses further includes a third lens disposed on the side of the first lens facing away from the second lens, and the lens structure further includes a first spacer abutting between the first lens and the third lens, and the first spacer extending into the receiving space and abutting the first portion in the radial direction of the lens barrel, the first portion also abutting the connecting surface in the axial direction of the lens barrel.

[0030] Therefore, by utilizing the cooperation between the first spacer and the connecting surface, the first part can be limited in the radial direction of the lens barrel, preventing the elastic spacer from moving randomly and causing the position of the elastic spacer to deviate. This ensures that the elastic spacer can always maintain close contact with the lens barrel and the second lens in the axial direction of the lens barrel, providing a more stable axial auxiliary support for the second lens, thereby improving the structural stability of the second lens and increasing the yield of the lens structure.

[0031] As an optional implementation, in the embodiment of the first aspect of this application, the lens structure further includes a first spacer;

[0032] The first spacer abuts between the first lens and the second lens, and extends into the accommodating spacer, abutting against the elastic spacer in the radial direction of the lens barrel, thereby restricting the displacement of the elastic spacer in the radial direction of the lens barrel; or,

[0033] The plurality of lenses further includes a third lens disposed on the side of the first lens facing away from the second lens. The first spacer abuts between the first lens and the third lens, and the first spacer extends into the accommodating space and abuts against the elastic spacer in the radial direction of the lens barrel to restrict the displacement of the elastic spacer in the radial direction of the lens barrel.

[0034] In the above design scheme, by reusing the first spacer, the first spacer can not only maintain the optical spacing between two adjacent lenses and prevent them from colliding with each other to better protect the lenses in the lens structure, but also abut against the elastic spacer to limit the elastic spacer in the radial direction of the lens barrel, preventing the elastic spacer from moving randomly and causing its position to deviate. This ensures that the elastic spacer can always maintain close contact with the lens barrel and the second lens in the axial direction of the lens barrel, providing a more stable axial auxiliary support for the second lens, thereby improving the structural stability of the second lens and increasing the yield of the lens structure.

[0035] As an optional implementation, in an embodiment of the first aspect of this application, the lens structure further includes a lens spacer, which is disposed between the first lens and the second lens, and extends radially along the lens barrel to abut against the elastic spacer and the second lens; thus, the second lens can still be provided with relatively stable axial auxiliary support by abutting against the elastic spacer through the lens spacer, and the lens spacer can also provide relatively stable axial auxiliary support, thereby improving the structural stability of the second lens and the lens spacer, and thus helping to further improve the yield of the lens structure.

[0036] And / or, the lens structure further includes a second spacer disposed between the first lens and the second lens, and the second spacer extends radially along the lens barrel to abut against the elastic spacer and the second lens. In this way, the second lens can still be provided with relatively stable axial auxiliary support by abutting against the elastic spacer through the second spacer, while also providing relatively stable axial auxiliary support to the lens spacer. This improves the structural stability of the second lens and the lens spacer, thereby further improving the yield rate of the lens structure.

[0037] Secondly, this application discloses a camera module having the lens structure described in the first aspect above. The camera module having the lens structure described in the first aspect can also compensate for errors in lens dimensional processing and assembly, providing more stable axial auxiliary support for lenses with larger diameters, reducing the overturning moment acting on larger lenses, thereby improving the structural stability of the lens and increasing the yield rate of the lens structure.

[0038] Thirdly, this application discloses an electronic device having a camera module as described in the second aspect above. Since the camera module described in the second aspect possesses the technical effects of the lens structure described in the first aspect, the electronic device having the camera module described in the second aspect can also compensate for errors in lens dimensional processing and assembly, providing more stable axial auxiliary support for lenses with larger diameters, reducing the overturning moment acting on larger lenses, thereby improving the structural stability of the lens and increasing the yield rate of the lens structure.

[0039] Compared with the prior art, the beneficial effects of this application are as follows:

[0040] The lens structure, camera module, and electronic device provided in this application embodiment utilize an elastic spacer that abuts against the second lens and the lens barrel in the axial direction. This allows the elastic spacer to support the second lens. Furthermore, the elastic spacer has a deformation space, which provides room for deformation, allowing or facilitating deformation to compensate for dimensional and assembly errors in the lens. This ensures that the elastic spacer maintains close contact with the lens barrel and the second lens in the axial direction, providing more stable axial support for the second lens, reducing the overturning moment acting on the second lens, and thus improving the structural stability of the second lens and increasing the yield rate of the lens structure.

Therefore, they should not be construed as limitations on this application.

[0065] The terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first lens may be referred to as a second lens, and similarly, a second lens may be referred to as a first lens. Both the first lens and the second lens are lenses, but they are not the same lens.

[0066] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0067] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0070] With the rapid growth of the consumer electronics market and the popularity of social media, video, and live streaming software, people have increasingly higher requirements for the image quality of camera lenses. Camera lenses have even become the primary indicator that consumers consider when purchasing electronic devices.

[0071] As the market share of mobile electronic products such as smartphones and tablets continues to increase, competition among manufacturers is becoming increasingly fierce. Camera lenses, as a crucial component of mobile electronic products, are undergoing rapid technological advancements. Among these, small-head, large-image-size lenses, due to their advantages such as high image quality, large depth of field, and short focal length, are widely used as front-facing cameras in mobile electronic products to increase screen-to-body ratio and possess broad market prospects.

[0072] In related technologies, small-head, large-image-plane lenses typically have two adjacent lenses with a significant diameter difference. When there is a large diameter difference between adjacent lenses, a spacer is usually used for transition. An auxiliary support surface is formed on the lens barrel at the position of the spacer along the axial direction of the lens barrel. The spacer and the auxiliary support surface of the lens barrel need to maintain a small axial gap (e.g., less than 7 micrometers) to ensure the structural stability of the spacer.

[0073] However, due to unavoidable manufacturing errors, and the greater the number of lenses, the greater the accumulated dimensional error of the lenses along the lens barrel axis. This makes it increasingly difficult to maintain the axial clearance between the spacer and the auxiliary support surface within the preset range. This is especially true when there are two or more auxiliary support surfaces inside the lens barrel. Combined with the accumulated dimensional error of multiple spacers along the lens barrel axis, it becomes even more difficult to ensure that the axial clearance between all spacers and auxiliary support surfaces is less than the preset value. This may result in the spacer being suspended. Furthermore, since the diameters of two adjacent lenses differ significantly, the points of force application on the spacer from these two adjacent lenses are far apart, resulting in a larger rotation torque. This leads to a decrease in the structural stability of the spacer, affecting its support effect on lenses with larger diameters. Consequently, the structural stability of the lenses is affected, leading to a decrease in the lens yield.

[0074] In view of this, embodiments of this application provide a lens structure, camera module, and electronic device that can compensate for the dimensional processing errors and assembly errors of the lens, and provide relatively stable axial auxiliary support for lenses with larger diameters.

[0075] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0076] This application provides an electronic device, which can be a mobile device, a terminal device, or a terminal, or it can be a camera module.

[0077] The technical solution of this application will be described in detail below, taking an electronic device as an example of a terminal device.

[0078] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the electronic device in one implementation of this application. Figure 2 yes Figure 1The diagram shows a partial cross-sectional view of one embodiment of the electronic device, cut along point AA. The electronic device 1000 may include a camera module 100, a device housing 200, a screen 300, and an image processor (not shown). The screen 300 is mounted on the device housing 200, with its display side facing away from the housing 200. The camera module 100 is mounted on the device housing 200 and located inside the electronic device 1000. The camera module 100 can be a front-facing camera module or a rear-facing camera module. The image processor is mounted on the device housing 200 and located inside the electronic device 1000, and is communicatively connected to the camera module 100.

[0079] It should be noted that, Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 As well as the accompanying drawings below. Furthermore, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300.

[0080] Furthermore, it should be noted that in the implementation of this application, the electronic device 1000 is only described as a smartphone as an example, and it is not limited to the electronic device 1000 being limited to smartphones. In other implementations of this application, the electronic device 1000 may also be a laptop computer, tablet computer, laptop computer, in-vehicle computer, camera, television, smart wearable device (such as smartwatch, smart wristband, smart glasses, earphone, etc.), personal digital assistant (PDA), augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses or VR helmet, e-book reader, or other electronic products with cameras. This application does not specifically limit this.

[0081] For example, the device housing 200 may include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. The back cover 202 can be fixed to the frame 201 by adhesive, or it can be an integral structure with the frame 201, that is, the back cover 202 and the frame 201 are an integral structure.

[0082] In this application, the screen 300 can be a flat screen or a curved screen, and it is mainly used to realize the screen display function of the electronic device 1000 of this application. The screen 300 is located on the side of the frame 201 away from the back cover 202. At this time, the screen 300 and the back cover 202 are respectively located on both sides of the frame 201, and the screen 300, the frame 201, and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house various electronic devices required by the electronic device 1000, such as the camera module 100, image processor, battery (not shown), temperature sensor (not shown), receiver (not shown), or microphone (not shown), etc.

[0083] In this way, the device housing 200 can fix and protect the screen 300, camera module 100, image processor, and other electronic devices or structures located inside the device housing 200 under external forces, such as drops, bumps, and collisions. It can also create a sealing effect on the screen 300, camera module 100, image processor, and other electronic devices or structures located inside the device housing 200 to prevent external moisture, dust, and other impurities from corroding the electronic devices or structures inside the device housing 200.

[0084] In this application, since the device housing 200 is generally directly exposed to the external environment, the material of the device housing 200 can have certain properties such as wear resistance, corrosion resistance and scratch resistance, or a layer of functional material for wear resistance, corrosion resistance and scratch resistance can be coated on the outer surface of the device housing 200 (that is, the outer surface of the electronic device 1000).

[0085] In some embodiments, the camera module 100 is located inside the electronic device 1000, and the camera module 100 can be fixed to the side of the back cover 202 facing the screen 300. The screen 300 can have a light-transmitting hole 203, wherein the shape of the light-transmitting hole 203 is not limited to the attached... Figure 1 The schematic circle is shown. The light-transmitting hole 203 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000, so that light from the exterior of the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting hole 203, thereby allowing the camera module 100 to capture the ambient light entering the interior of the electronic device 1000.

[0086] In other embodiments, the camera module 100 is located inside the electronic device 1000, and the camera module 100 can be fixed to the side of the back cover 202 facing the screen 300. The back cover 202 can have a light-transmitting hole 203, which connects the inside of the electronic device 1000 to the outside of the electronic device 1000, so that light from the outside of the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting hole 203, thereby enabling the camera module 100 to collect the ambient light entering the inside of the electronic device 1000.

[0087] Understandable, Figure 1 The installation position of the camera module 100 in the illustrated embodiment of the electronic device 1000 is merely illustrative, and this application does not strictly limit the installation position of the camera module 100. In some embodiments, the camera module 100 may also be installed in other locations of the electronic device 1000, for example, the camera module 100 may also be installed in the upper middle part or the upper right corner of the electronic device 1000. In other embodiments, the electronic device 1000 may include a device body and an auxiliary component that can rotate, move, or be detached relative to the device body. In this case, the camera module 100 may also be disposed on the auxiliary component so that the camera module 100 can rotate, move, or be detached relative to the device body.

[0088] like Figure 2 As shown, the camera module 100 provided in this embodiment includes a lens structure 10 and an image sensor 20. The lens structure 10 is used to receive the light signal from the subject and project it onto the image sensor 20. The image sensor 20 is used to receive the light signal collected by the lens structure 10, process the light signal, and finally achieve imaging.

[0089] In this application, the image processor can be communicatively connected to the image sensor 20 of the camera module 100, enabling the image processor to acquire and process image data from the image sensor 20 of the camera module 100. The communication connection between the image sensor 20 of the camera module 100 and the image processor can include data transmission via electrical connections such as wiring, or data transmission via coupling or other methods. It is understood that the image sensor 20 of the camera module 100 and the image processor can also achieve a communication connection through other methods capable of data transmission.

[0090] The image processor's function is to optimize the digital image signal through a series of complex mathematical algorithms, and finally transmit the processed signal to the screen 300. The image processor can be an image processing chip or a digital signal processing chip.

[0091] Please see Figure 3The lens structure 10 provided in this application embodiment includes a lens barrel 11, a plurality of lenses 12, and at least one elastic spacer 13. The plurality of lenses 12 are arranged in the lens barrel 11 along the axial direction (corresponding to the y-axis direction in the figure). The plurality of lenses 12 include a first lens 121 and a second lens 122 arranged adjacent to each other. The radial dimension of the first lens 121 is smaller than the radial dimension of the second lens 122. An accommodating space 111 is formed between the first lens 121, the second lens 122, and the lens barrel 11. The elastic spacer 13 is disposed in the accommodating space 111. In the axial direction of the lens barrel 11, the elastic spacer 13 abuts between the second lens 122 and the lens barrel 11. Thus, the elastic spacer 13 can support the second lens 122 together with the first lens 121. In the axial direction of the lens barrel 11, the elastic spacer 13 has a deformation space 131, which allows the elastic spacer 13 to deform in the axial direction of the lens barrel.

[0092] In other words, in the lens structure 10 provided in this application embodiment, by setting an elastic spacer 13 and having the elastic spacer 13 abut against the second lens 122 and the lens barrel 11 in the axial direction, the elastic spacer 13 can support the second lens 122. Moreover, the elastic spacer 13 has a deformation space 131, and the setting of the deformation space 131 can provide space for the deformation of the elastic spacer 13, allowing or facilitating the deformation of the elastic spacer 13 to compensate for the dimensional processing error and assembly error of the lens 12. This ensures that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11, preventing the second lens 122 from being suspended. This provides a more stable axial auxiliary support for the second lens 122, reduces the overturning moment acting on the second lens 122, and thus helps to improve the structural stability of the second lens 122 and increase the yield of the lens structure 10.

[0093] Optionally, the elastic spacer 13 may be made of elastic materials such as silicone, rubber, plastic or foam, but is not limited to these materials.

[0094] In some embodiments, the elastic spacer 13 contacts the lens barrel 11 in the radial direction (corresponding to the x-axis direction in the figures). Thus, when the elastic spacer 13 is installed into the lens barrel 11, the elastic spacer 13 can be installed along the inner wall surface of the lens barrel 11 to a preset position. The inner wall surface of the lens barrel 11 guides the installation of the elastic spacer 13, facilitating the installation of the elastic spacer 13.

[0095] For ease of description, this application defines the projection of the first lens 121 onto the second lens 122 as the first projection, and the projection of the elastic spacer 13 onto the second lens 122 as the second projection. It should be understood that the above definitions are merely for ease of description and should not be used to limit the scope of protection of this application.

[0096] In some embodiments, the first projection and the second projection are spaced apart or tangentially arranged, meaning that the first projection and the second projection do not overlap or coincide. This arrangement implies that the first lens 121 and the elastic spacer 13 do not overlap or coincide in the axial direction of the lens barrel 11, and there is no mutual contact between them. Compared to a arrangement where the elastic spacer 13 partially abuts between the first lens 121 and the second lens 122, this reduces the force exerted by the second lens 122 on the first lens 121 through the elastic spacer 13. This allows the elastic spacer 13 to better distribute the force exerted by the second lens 122 on the first lens 121, thereby reducing the stress on the first lens 121. This, in turn, helps to reduce the risk of cracks or fissures in the first lens 121 due to excessive stress, ensuring the service life and optical performance of the first lens 121.

[0097] It is understandable that the force exerted by the second lens 122 on the first lens 121 can be the force exerted by the pressure ring directly or indirectly squeezing the second lens 122 during assembly, causing the second lens 122 to squeeze the first lens 121; it can also be the force exerted by the second lens 122 moving towards the first lens 121 and squeezing the first lens 121 when the lens structure 10 is dropped; or it can be the force exerted by the second lens 122 expanding due to the high temperature environment of the lens structure 10, causing the second lens 122 to squeeze the first lens 121.

[0098] In this application, the lens structure 10 has an optical axis O.

[0099] In some embodiments, such as Figure 3 and Figure 4 As shown, the elastic spacer 13 has a first surface 13a facing the second lens 122 and a second surface 13b facing the optical axis O. A chamfer 13c, such as a rounded corner or a bevel, is provided at the junction of the first surface 13a and the second surface 13b. During installation, this chamfer 13c can guide and remind the assembler to install the elastic spacer 13 according to the preset installation direction, avoiding the installation of a rebound spacer 13, thus preventing mistaken installation and facilitating the assembly of the elastic spacer 13.

[0100] In some embodiments, the first surface 13a is provided with a recess 13d that penetrates the second surface 13b. During installation, the recess 13d can be used to guide and remind the assembler to install the elastic spacer 13 in the preset installation direction, avoiding the installation of the rebound spacer 13, thus preventing mistake and facilitating the installation of the elastic spacer 13.

[0101] In some embodiments, there may be one or more elastic spacers 13. When there are multiple elastic spacers 13, the multiple elastic spacers 13 are stacked along the axial direction of the lens barrel 11.

[0102] In some embodiments, the elastic spacer 13 may be a square structure with a hollowed-out center forming a deformable space 131.

[0103] In some embodiments, the elastic spacer 13 may be generally Z-shaped, having a first radial portion and a second radial portion extending radially along the lens barrel 11, the first radial portion and the second radial portion being spaced apart and connected by an inclined portion, the inclined portion being inclined relative to the first radial portion and the second radial portion, the first radial portion abutting against the lens barrel in the axial direction of the lens barrel, the second radial portion abutting against the second lens, wherein the deformation space includes a first space formed between the first radial portion and the inclined portion, and a second space formed between the second radial portion and the inclined portion.

[0104] In some embodiments, such as Figure 3 and Figure 4 As shown, the deformation space 131 extends through the side of the elastic spacer 13 on the radial side (corresponding to the x-axis direction in the figure) of the lens barrel 11, so that an opening 132 is formed on the side of the elastic spacer 13 on the radial side of the lens barrel 11. In this embodiment, the elastic spacer 13 is generally C-shaped or U-shaped.

[0105] The elastic spacer 13 adopts the above-described structure. The sidewall of the elastic spacer 13 that abuts against the second lens 122 is equivalent to an elastic arm with one end as the connecting end and the other end as the free end. The free end of the elastic arm is suspended. When the elastic arm is squeezed by the second lens 122, the elastic arm can deform more easily, buffering the force on the second lens 122 to protect it. At the same time, it can generate a larger deformation. Thus, even if the lens 12 has dimensional processing errors and assembly errors, corresponding error compensation can be performed to ensure that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11. This can provide a more stable axial auxiliary support for the second lens 122, reduce the overturning moment acting on the second lens 122, and thus help improve the structural stability of the second lens 122 and increase the yield of the lens structure 10.

[0106] In addition, the opening direction of the elastic spacer 13 extends radially along the lens barrel 11. Compared with the way the opening direction of the elastic spacer 13 extends axially along the lens barrel 11, it can ensure that the elastic spacer 13 has a larger contact area with the second lens 122 and the lens barrel 11 in the axial direction of the lens barrel 11. This can provide more stable axial auxiliary support for the second lens 122, which is conducive to further improving the structural stability of the second lens 122 and further improving the yield of the lens structure 10.

[0107] In some embodiments, such as Figure 5 As shown, the deformation space 131 extends through the side of the elastic spacer 13 facing the optical axis O, that is, the opening 132 of the elastic spacer 13 is arranged facing the optical axis O.

[0108] In other embodiments, such as Figure 6 As shown, the deformation space 131 extends through the side of the elastic spacer 13 facing away from the optical axis O, that is, the opening 132 of the elastic spacer 13 is set facing away from the optical axis O, so that the edge of the elastic spacer 13 away from the optical axis O has a free end.

[0109] Since the stress points of each lens 12 are mainly located at the edges of the lens 12 away from the optical axis O, the second lens 122 mainly compresses the elastic spacer 13 away from the optical axis O at its edge away from the optical axis O. By setting the opening 132 of the elastic spacer 13 to face away from the optical axis O, that is, the opening 132 is formed on the outer peripheral surface of the elastic spacer 13 away from the optical axis O, the stress point of the second lens 122 acting on the elastic spacer 13 can be close to or located at the free end of the elastic spacer 13. This makes it easier for the elastic spacer 13 to deform when subjected to the compression of the second lens 122, thus mitigating the stress. The force applied to the second lens 122 is used to protect it, while also generating a larger forming variable. Thus, even if the lens 12 has dimensional processing errors and assembly errors, corresponding error compensation can be performed to ensure that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11. This provides a more stable axial auxiliary support for the second lens 122, reduces the overturning moment acting on the second lens 122, and thus helps to improve the structural stability of the second lens 122 and increase the yield of the lens structure 10.

[0110] In some embodiments, in the orthographic projection along the axis of the lens barrel 11, the orthographic projection of the contact area between the second lens 122 and the elastic spacer 13 falls within the orthographic projection range of the deformation space 131. This allows the force point of the second lens 122 acting on the elastic spacer 13 to correspond to the deformation space 131, thereby making it easier for the elastic spacer 13 to deform when subjected to the compression of the second lens 122, thus buffering the force on the second lens 122 and protecting it.

[0111] In some embodiments, such as Figure 7 and Figure 8 As shown, the elastic spacer 13 includes a first portion 133 and a second portion 134 connected at an angle to the first portion 133. The first portion 133 extends along the axial direction of the lens barrel 11 and abuts against the lens barrel 11 in the axial direction. A deformation space 131 is formed between the second portion 134 and the first portion 133. The second portion 134 extends radially along the lens barrel 11 and in a direction away from the optical axis. The second portion 134 abuts against the second lens 122 in the axial direction of the lens barrel 11 and is spaced apart from the lens barrel 11 in the axial direction of the lens barrel 11. Thus, the gap between the second portion 134 and the lens barrel 11 can provide space for the deformation of the second portion 134.

[0112] In the above scheme, the second part 134 is deformed by the action of the second lens 122. The second part 134 is equivalent to an elastic arm with one end as the connecting end and the other end as the free end. The free end is suspended. When the second part 134 is squeezed by the second lens 122, the second part 134 can deform more easily, buffering the force on the second lens 122 to protect the second lens 122. At the same time, it can generate a larger deformation. Therefore, even if the lens 12 has dimensional processing errors and assembly errors, corresponding error compensation can be performed to ensure that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11. This can provide a more stable axial auxiliary support for the second lens 122, reduce the overturning moment acting on the second lens 122, and thus help improve the structural stability of the second lens 122 and increase the yield of the lens structure 10.

[0113] Furthermore, the second part 134 extends radially along the lens barrel 11 and away from the optical axis, allowing the force point of the second lens 122 acting on the second part 134 to be close to or located at the free end of the second part 134. This makes it easier for the second part 134 to deform when subjected to the squeezing action of the second lens 122, buffering the force on the second lens 122 to protect it. At the same time, it can generate a larger forming variable. Thus, even if the lens 12 has dimensional processing errors and assembly errors, corresponding error compensation can be performed to ensure that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11. This can provide a more stable axial auxiliary support for the second lens 122, reduce the overturning moment acting on the second lens 122, and thus help improve the structural stability of the second lens 122 and increase the yield of the lens structure 10.

[0114] In some embodiments, such as Figure 8As shown, a groove 135 is provided at the connection between the first part 133 and the second part 134. The groove 135 extends radially along the lens barrel 11, and the groove 135 faces the lens barrel 11.

[0115] This configuration allows the first part 133 and the second part 134 to work together as the elastic arm of the elastic spacer 13, increasing the arm length of the elastic spacer 13. This makes the second part 134 more prone to deformation when subjected to the compression of the second lens 122, buffering the force on the second lens 122 to protect it. It also generates a larger forming variable, thus allowing for compensation even if the lens 12 has dimensional processing errors or assembly errors. This ensures that the elastic spacer 13 maintains close contact with the lens barrel 11 and the second lens 122 along the axial direction of the lens barrel 11, providing more stable axial auxiliary support for the second lens 122, reducing the overturning moment acting on the second lens 122, and ultimately improving the structural stability of the second lens 122 and increasing the yield of the lens structure 10.

[0116] In some embodiments, such as Figure 7 and Figure 8 As shown, the inner wall surface of the lens barrel 11 is formed with a first stepped surface 112 and a second stepped surface 113 arranged at intervals along the axial direction of the lens barrel 11. The first stepped surface 112 and the second stepped surface 113 are connected by a connecting surface 114. In the axial direction of the lens barrel 11, the second stepped surface 113 is closer to the second lens 122 than the first stepped surface 112. An accommodating space 111 is formed between the first stepped surface 112, the connecting surface 114, the second stepped surface 113, the first lens 121, and the second lens 122. In the axial direction of the lens barrel 11, the first part 133 abuts against the first stepped surface 112, and the second part 134 is spaced apart from the second stepped surface 113. Thus, the gap between the second part 134 and the second stepped surface 113 can provide space for the deformation of the second part 134.

[0117] In the above design structure, since the second step surface 113 is closer to the second lens 122 than the first step surface 112 in the axial direction of the lens barrel 11, the distance between the second step surface 113 and the second part 134 in the axial direction of the lens barrel 11 is smaller than the distance between the first step surface 112 and the second part 134. Therefore, when the second part 134 deforms to a certain extent, the second step surface 113 abuts against the second part 134 to prevent the second part 134 from continuing to deform, avoid excessive deformation of the second part 134, and thus avoid irreversible deformation of the second part 134, which would lead to elastic failure and affect its use.

[0118] In some embodiments, in the radial direction of the lens barrel 11, the first portion 133 abuts between the first lens 121 and the connecting surface 114. That is, the first portion 133 abuts both the first lens 121 and the connecting surface 114. Thus, the cooperation between the first lens 121 and the connecting surface 114 can limit the first portion 133 in the radial direction of the lens barrel 11, preventing the elastic spacer 13 from moving arbitrarily and causing the position of the elastic spacer 13 to deviate. This ensures that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11, providing a more stable axial auxiliary support for the second lens 122, thereby improving the structural stability of the second lens 122 and increasing the yield of the lens structure 10.

[0119] In some embodiments, the lens structure 10 further includes a first spacer 14.

[0120] An example, such as Figure 5 and Figure 6 As shown, the first spacer 14 can abut between the first lens 121 and the second lens 122, and the first spacer 14 extends into the receiving space 111. The first spacer 14 abuts against the elastic spacer 13 in the radial direction of the lens barrel 11 to restrict the displacement of the elastic spacer 13 in the radial direction of the lens barrel 11.

[0121] Another example, such as Figure 7 and Figure 8 As shown, the plurality of lenses 12 also includes a third lens 123, which is disposed on the side of the first lens 121 facing away from the second lens 122. The first spacer 14 can abut between the first lens 121 and the third lens 123, and the first spacer 14 extends into the receiving space 111. The first spacer 14 abuts against the elastic spacer 13 in the radial direction of the lens barrel 11 to restrict the displacement of the elastic spacer 13 in the radial direction of the lens barrel 11.

[0122] In the above design scheme, by reusing the first spacer 14, the first spacer 14 can not only maintain the optical spacing between two adjacent lenses 12 and prevent them from colliding with each other to better protect the lenses 12 in the lens structure 10, but also abut against the elastic spacer 13 to limit the elastic spacer 13 in the radial direction of the lens barrel 11, preventing the elastic spacer 13 from moving randomly and causing its position to deviate. This ensures that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11, providing a more stable axial auxiliary support for the second lens 122, thereby improving the structural stability of the second lens 122 and increasing the yield of the lens structure 10.

[0123] Specifically, when the elastic spacer 13 has an opening 132 communicating with the deformation space 131 on the radial (corresponding to the x-axis direction in the figure) side of the lens barrel 11, if the opening 132 of the elastic spacer 13 is oriented towards the optical axis, the first spacer 14 abuts against the side wall of the elastic spacer 13 and the lens barrel 11; if the opening 132 of the elastic spacer 13 is oriented away from the optical axis, the first spacer 14 abuts against the side of the elastic spacer 13 opposite to the opening 132.

[0124] When the elastic spacer 13 includes a first portion 133 and a second portion 134 connected at an angle to the first portion 133, the elastic spacer 13 abuts against the first portion 133 in the radial direction of the lens barrel 11, and the first portion 133 also abuts against the connecting surface 114 in the axial direction of the lens barrel 11. Thus, the cooperation between the first lens 121 and the connecting surface 114 can limit the first portion 133 in the radial direction of the lens barrel 11, preventing the elastic spacer 13 from shifting arbitrarily and causing positional deviation. This ensures that the elastic spacer 13 can always maintain close contact with the lens barrel 11 and the second lens 122 in the axial direction of the lens barrel 11, providing relatively stable axial auxiliary support for the second lens 122, thereby improving the structural stability of the second lens 122 and increasing the yield of the lens structure 10.

[0125] It should be noted that, in some embodiments, the first portion 133 may only abut against the first lens 121 and the connecting surface 114 in the radial direction of the lens barrel 11; in other embodiments, the first portion 133 may only abut against the first spacer 14 and the connecting surface 114 in the radial direction of the lens barrel 11; and in still other embodiments, the first portion 133 may abut against the first lens 121, the first spacer 14, and the connecting surface 114 in the radial direction of the lens barrel 11.

[0126] In some embodiments, such as Figure 9 and Figure 10 As shown, the lens structure 10 also includes a lens spacer 15, which is disposed between the first lens 121 and the second lens 122. The lens spacer 15 extends radially along the lens barrel 11 to abut against the elastic spacer 13 and the second lens 122. Thus, the second lens 122 can still be provided with relatively stable axial auxiliary support by abutting against the elastic spacer 13 through the lens spacer 15. Simultaneously, the lens spacer 15 can also provide relatively stable axial auxiliary support, thereby improving the structural stability of the second lens 122 and the lens spacer 15, and further improving the yield rate of the lens structure 10.

[0127] In some embodiments, combined with Figures 11 to 14As shown, the lens structure 10 also includes a second spacer 16, which is disposed between the first lens 121 and the second lens 122, and extends radially along the lens barrel 11 to abut against the elastic spacer 13 and the second lens 122. In this way, the second lens 122 can still be provided with relatively stable axial auxiliary support by abutting against the elastic spacer 13 through the second spacer 16, and at the same time, it can also provide relatively stable axial auxiliary support for the lens spacer 15, thereby improving the structural stability of the second lens 122 and the lens spacer 15, and thus further improving the yield of the lens structure 10.

[0128] When both the lens spacer 15 and the second spacer 16 are present, both the lens spacer 15 and the second spacer 16 are located between the first lens 121 and the second lens 122. The lens spacer 15 can be located between the second spacer 16 and the second lens 122, in which case the second spacer 16 is in direct contact with the elastic spacer 13 and the first lens 121. Alternatively, the second spacer can be located between the lens spacer 15 and the second lens 122, in which case the lens spacer 15 is in direct contact with the elastic spacer 13 and the first lens 121.

[0129] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0130] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
