[0007] The liquid damping medium is filled in the first inner cavity and the second inner cavity, so that when the carrier and the lens generate relative movement, the liquid damping medium is caused to flow slowly between the first inner cavity and the second inner cavity through the flow channel and form fluid damping synchronously, thereby buffering the transient impact between the carrier and the lens barrel;

[0008] The resetting member is connected between the carrier and the partition plate to drive the lens barrel and the carrier to reset to a preset relative position.

[0009] In some embodiments, sealing flanges are convexly provided on the inner side surfaces of both ends of the carrier, and the sealing flanges abut against the outer peripheral surface of the lens barrel.

[0021] The shooting lens and camera module provided in the embodiment of the present application are provided with a carrier outside the lens barrel, and an annular cavity is formed between the carrier and the lens barrel for filling with a liquid damping medium, and then a partition plate is mounted outside the lens barrel to divide the annular cavity into a first inner cavity and a second inner cavity, which are connected only through the flow channel on the partition plate, so that when the lens barrel moves relative to the carrier, the liquid damping medium is compressed through the flow channel to generate linear liquid damping, which hinders the instantaneous large relative movement between the lens barrel and the carrier, thereby achieving the effect of buffering the impact of the lens barrel; it is worth mentioning that the hysteresis characteristic of the state change of the liquid damping medium makes it impossible for it to flow at high speed instantly, thereby being able to delay and weaken the amplitude of the instantaneous movement of the lens to a certain extent, thereby realizing the buffering function; and the flow channel on the partition plate can realize a small flow of the liquid damping medium in the two chambers, leaving space for the movement of the lens barrel, so that the partition plate and the connected lens barrel can have a small movement, thereby absorbing the high-speed impact energy of the lens barrel, weakening the movement amplitude of the lens barrel, thereby avoiding large relative movement of the lens barrel and its internal inner lens group, ensuring the stability of the functional structure of the lens barrel, and reducing the risk of damage to the lens barrel. On the other hand, considering that the fluidity of the liquid damping medium is poor and the lens barrel cannot be actively reset, a reset member can be connected between the carrier and the lens barrel to generate a force that causes the lens barrel to reset when the lens barrel shifts relative to the carrier, so that after the lens barrel buffering is completed, it is gradually reset to ensure the position stability of the lens group in the lens barrel.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0039] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0040] A lens is usually composed of a lens barrel and a lens group arranged inside it. Under certain severe vibration and impact conditions, the lens will produce a specific impact along its optical axis relative to the main body of the shooting equipment, which may cause damage to the lens, such as deformation and breakage of the lens, or displacement and deformation of the lens group inside the lens barrel.

[0041] To this end, the embodiments of the present application provide a shooting lens and a camera module, which aim to improve the impact resistance of the shooting lens to a certain extent, reduce the risk of impact damage, and maintain the reliability of the lens shooting function.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the shooting lens can be configured as an optical lens, that is, it can be configured to receive light and transmit it to a subsequent processing mechanism after optical processing; such as an imaging chip, etc. The shooting lens may include: a lens barrel 100, a carrier 200, a partition plate 300, a liquid damping medium 400 and a reset member 500; the lens barrel 100 is movably arranged in the carrier 200, the partition plate 300 is sleeved on the lens barrel 100 and is located in the carrier 200; the liquid damping medium 400 is arranged in the annular cavity 110 between the carrier 200 and the lens barrel 100; the reset member 500 is connected between the carrier 200 and the lens barrel 100 or the partition plate 300.

[0043] The lens barrel 100 is a carrier of the lens group of the lens, and a lens group placement structure, such as a slot, can be configured inside the lens barrel 100 for fixing various functional lenses. Generally speaking, the lens barrel 100 can be configured as a cylindrical member, and the inner barrel cavity can be configured as a light channel.

[0044] The carrier 200 can be set as the installation base of the shooting lens, and is used to install the shooting lens as a whole on the main structure of the shooting device; accordingly, the carrier 200 can be connected to the lens barrel 100, and the lens barrel 100 can be carried and installed. Specifically, the carrier 200 can be set as a cylindrical member, and the inner diameter of the barrel cavity is larger than the outer diameter of the lens barrel 100. The lens barrel 100 is movably arranged in the barrel of the carrier 200, and an annular cavity 110 is formed between the carrier 200 and the lens barrel 100, which is used to store the liquid damping medium 400.

[0045] The partition plate 300 is sleeved on the outer circumferential surface of the lens barrel 100, and the partition plate 300 is arranged in the annular cavity 110, and the annular cavity 110 is divided into a first inner cavity 111 and a second inner cavity 112 along the axial direction of the lens barrel 100; a flow channel 310 is opened on the partition plate 300 to connect the first inner cavity 111 and the second inner cavity 112; so that the liquid damping medium 400 can flow slowly between the first inner cavity 111 and the second inner cavity 112 through the flow channel 310, and simultaneously form linear damping, so that the impact energy between the lens barrel 100 and the carrier 200 can be absorbed to a certain extent by the flowing liquid damping medium 400, thereby buffering and weakening the relative movement between the lens barrel 100 and the carrier 200, and protecting the lens barrel 100 and the lens group inside the lens barrel 100. On the other hand, when the lens barrel 100 moves relative to the carrier 200, the partition plate 300 synchronously compresses the liquid damping medium 400 and forces it to pass through the flow channel 310, thereby leaving an escape space to avoid a rigid collision between the partition plate 300 and the lens barrel 100 and the liquid damping medium 400, thereby further improving the impact resistance of the shooting lens.

[0046] The reset member 500 is configured as a functional mechanism for driving the lens barrel 100 to reset, and is used to drive the lens barrel 100 to reset after the lens barrel 100 is impact-displaced relative to the carrier 200, so that the lens group in the lens barrel 100 is reset to ensure the shooting quality of the shooting lens. To this end, the reset member 500 can be connected between the carrier 200 and the lens barrel 100 or the partition plate 300, and once the lens barrel 100 is impact-displaced, the reset member 500 synchronously generates a reset force. Generally speaking, the reset member 500 can be arranged in the annular cavity 110 and connected to the partition plate 300 and the carrier 200 respectively; or, the reset member 500 can also be arranged outside the annular cavity 110, and the reset member 500 can be directly connected to the lens barrel 100 and the carrier 200. In the following embodiments, the case where the reset member 500 is arranged inside the annular cavity 110 is described as an example.

[0047] That is to say, after the shooting lens is installed on the shooting device, the carrier 200 can be connected to the matching structure on the shooting device to realize the installation of the shooting lens; when subjected to severe impact, the lens barrel 100 can move along its axial direction, and the lens barrel 100 compresses the liquid damping medium 400 on one side of the partition plate 300 through the partition plate 300 connected thereto, thereby absorbing the impact energy, weakening the impact strength, limiting the displacement of the lens barrel 100 and the lens group inside it, and avoiding damage to the lens barrel 100 and the lens group inside it, thereby achieving buffering of transient impacts between the carrier 200 and the lens barrel 100, and ensuring the reliability of the functional structure of the shooting lens.

[0048] See also Figure 4 and Figure 7 In some embodiments, in order to improve the sealing performance of the annular cavity 110 between the carrier 200 and the lens barrel 100, a sealing structure may be provided at both ends of the barrel of the carrier 200 to form a sliding sealing state with the outer peripheral surface of the lens barrel 100 to ensure the sealing performance of the annular cavity 110.

[0049] Specifically, a sealing flange 210 pointing to the central axis of the carrier can be protruded on the inner side surface of the carrier 200, and the sealing flange 210 can be set to be annular, abutting against the outer peripheral surface of the lens barrel 100, slidingly sealing the gap between the carrier 200 and the outer peripheral surface of the lens barrel 100.

[0050] In some embodiments, in order to enhance the sealing reliability of the sealing flange 210 , a sealing member 220 may be provided between the sealing flange 210 and the outer peripheral surface of the lens barrel 100 , so that the sealing member 220 can adaptively deform under the extrusion of the sealing flange 210 and the lens barrel 100 to fill and seal the gap between the carrier 200 and the lens barrel 100 .

[0051] Generally speaking, the sealing member 220 can be configured as a sealing ring 221 , a sealing sleeve, or the like that can match the outer circumference of the lens barrel 100 .

[0052] In some embodiments, in order to maintain the position of the seal 220 and prevent the seal 220 from shifting when the carrier 200 and the lens barrel 100 move relative to each other, a mounting groove 211 may be provided on the sealing flange 210 for matching and mounting the seal 220 .

[0053] Generally speaking, the installation groove 211 can be configured as a semicircular arc groove, and the sealing member 220 can be configured as a sealing ring 221 .

[0054] In some embodiments, the sealing flange 210 may be integrally formed with the carrier to facilitate molding and avoid assembly gaps caused by using separate components, thereby relatively improving the sealing performance.

[0055] In some embodiments, the carrier 200 may be a regular rotating cylinder-shaped piece, forming a regular whole, so as to obtain good adaptability and facilitate assembly in various postures.

[0056] See also Figure 4 , Figure 5 , Figure 6 and Figure 8 In some embodiments, in order to facilitate the installation of the partition plate 300, the carrier 200 can be divided into two parts that can be connected and fixed along its axial direction, namely, a carrier body 241 and a sealing cover 242; during assembly, the partition plate 300 is first assembled on the lens barrel 100, and then the carrier body 241 and the sealing cover 242 are sleeved on the lens barrel 100, and then the carrier body 241 and the sealing cover 242 are assembled into the carrier 200, thereby simplifying the assembly operation.

[0057] Generally speaking, the two parts of the carrier 200 can be bonded with an adhesive material, that is, the adhesive material is coated on the joint surface of the carrier 241 and the sealing cover 242, and then the carrier 241 and the sealing cover 242 are aligned and spliced ​​while maintaining appropriate pressure. After the adhesive material layer is cured, the splicing and installation of the carrier 200 is completed.

[0058] In some embodiments, the partition plate 300 can be directly formed on the outer peripheral surface of the lens barrel 100 and can be integrally formed by a mold, thereby improving the assembly firmness of the partition plate 300 and the lens barrel 100 to a certain extent, maintaining the stability of the installation position and posture of the partition plate 300 in the lens barrel 100, and maintaining the reliability of the impact resistance of the lens barrel 100.

[0059] In some embodiments, the partition plate 300 and the lens barrel 100 may also be configured as two independent components, and the partition plate 300 may be configured as an annular plate, that is, a mounting hole 320 is provided on the partition plate 300 that passes through the plate body, and the partition plate 300 may be integrally mounted on the lens barrel 100 through the mounting hole 320.

[0060] Generally speaking, an adhesive material may be provided between the partition plate 300 and the lens barrel 100 to bond the partition plate 300 and the lens barrel 100 together, thereby enhancing the installation strength and maintaining the stability of the posture and position of the partition plate 300 .

[0061] See also Figure 5 and Figure 6In some embodiments, in order to further enhance the stability of the installation posture and position of the partition plate 300, the partition plate 300 may include a plate body 330 and a sleeve 340; the installation hole 320 is provided on the plate body 330, the sleeve 340 is connected to the plate body 330, and the barrel cavity of the sleeve 340 is directly connected to the installation hole 320, so that the plate body 330 and the sleeve 340 can be sleeved on the lens barrel 100 together. The inner cylinder surface of the sleeve 340 and the outer peripheral surface of the lens barrel 100 have a large contact area, so that the stability of the installation position and posture of the sleeve 340 can be maintained, thereby enhancing the stability of the installation position and posture of the plate body 330 to a certain extent.

[0062] Generally speaking, a bonding material may be filled between the sleeve 340 and the lens barrel 100 to further enhance the installation posture and position stability of the sleeve 340 .

[0063] In some embodiments, the plate body 330 and the sleeve 340 may be integrally formed by a mold, thereby improving the connection strength, matching position and posture stability and reliability of the plate body 330 and the sleeve 340 to a certain extent.

[0064] In some embodiments, the flow channel 310 can be realized by opening a plurality of indentations 311 on the edge of the plate body 330 of the partition plate 300 , and the indentation direction of the indentations 311 is the radial direction of the plate body 330 .

[0065] Generally speaking, the number of the notches 311 may be more than two, and the two or more notches 311 may be arranged at equal intervals on the circumferential edge of the partition plate 300 .

[0066] In some cases, the flow channel 310 may also be realized by a through hole penetrating the plate body 330 of the partition plate 300 , that is, a plurality of through holes are evenly provided on the plate body 330 of the partition plate 300 to communicate the two sides of the plate body 330 .

[0067] Generally speaking, there are multiple through holes; the through holes can be set as round holes.

[0068] See also Figure 3 and Figure 4In some embodiments, the liquid damping medium 400 has a certain fluidity to absorb impact energy through liquid flow, and also has a certain viscosity, and the flow capacity should not be too large, so as to greatly reduce the impact oscillation amplitude of the liquid damping medium 400 and maintain the uniformity of the distribution of the liquid damping medium 400. The first inner cavity 111 and the second inner cavity 112 are filled with sufficient liquid damping medium 400, so that when the partition plate 300 and the lens barrel 100 are impacted, the liquid damping medium 400 can immediately implement energy absorption and buffering to protect the partition plate 300 and the lens barrel 100.

[0069] Generally speaking, the liquid damping medium 400 can be damping oil, i.e., oily damping medium, which has certain compression resistance, fluidity, and viscosity; for example, the liquid damping medium 400 can be No. 45 hydraulic oil. Of course, the liquid damping medium 400 can also be a fluid medium of other materials, and have certain fluidity and viscosity.

[0070] See also Figure 1 and Figure 3 In some embodiments, the reset member 500 may include an elastic reset member 510, and the elastic reset member 510 is connected between the partition plate 300 and the carrier 200, and applies an elastic reset force to the partition plate 300 based on the carrier 200, thereby prompting the lens barrel 100 to reset to a preset position.

[0071] That is, the elastic reset member 510 can be connected between the carrier 200 and the partition plate 300, and maintain the initial elastic force and be in a balanced state, so that the partition plate 300 and the lens barrel 100 are in a preset initial position; once the lens barrel 100 is impacted and moved, the force balance state of the elastic reset member 510 will be destroyed, and the elastic reset member 510 will apply a larger elastic force to the outside, prompting the lens barrel 100 and the partition plate 300 to reset to the initial position.

[0072] In some embodiments, the elastic return member 510 can adopt a spring 511 and be disposed in the annular cavity 110. The spring 511 can be mounted on the lens barrel 100, and the two ends of the spring 511 respectively abut against the plate surface of the partition plate 300 and the sealing flange 210 of the carrier 200.

[0073] In some embodiments, the elastic return member 510 may also be other types of elements, such as a reed.

[0074] In some embodiments, in order to improve the effect of the reset member 500, balance the forces on both sides of the lens barrel 100 and take into account the reset operations in two reset directions, the reset member 500 can be provided in two groups, and the two groups of reset members 500 are respectively connected between the two sides of the partition plate 300 and the carrier 200, so as to realize the forces and balance on both sides of the lens barrel 100.

[0075] Correspondingly, when the spring 511 is used as the reset member 500 , both ends of the spring 511 are connected between the side plate surface of the partition plate 300 and the carrier 200 .

[0076] In some embodiments, an annular limiting groove 230 can be opened on the inner wall of the carrier 200, and the width of the limiting groove 230 in the axial direction of the carrier 200 and the lens barrel 100 can match the length of the moving stroke range of the partition plate 300, which can limit the further movement of the partition plate 300 to a certain extent, thereby preventing the lens barrel 100 from moving excessively and damaging the surrounding equipment.

[0077] In some embodiments, a camera module equipped with the above-mentioned shooting lens is also provided, including: a camera module, including: a shell, an image sensor, a module circuit and the shooting lens; the image sensor is arranged in the shell, and the image sensor is connected to the module circuit; the carrier is installed in the shell, and the light-emitting side of the lens barrel is opposite to the image sensor, so that the incident light passing through the lens barrel can be projected onto the image sensor to complete the shooting.

[0078] The shooting lens can be mounted on the housing via the carrier, so that the camera module also has good impact resistance.

[0079] The embodiments of the present application have at least the following beneficial effects:

[0080] The shooting lens and shooting device provided by the embodiment of the present application are provided with a carrier outside the lens barrel, and an annular cavity is formed between the carrier and the lens barrel for filling with a liquid damping medium, and then a partition plate is installed outside the lens barrel to divide the annular cavity into a first inner cavity and a second inner cavity, which are connected only through the flow channel on the partition plate, so that when the lens barrel moves relative to the carrier, the liquid damping medium is compressed through the flow channel to generate linear liquid damping, which hinders the instantaneous large relative movement between the lens barrel and the carrier, thereby achieving the effect of buffering the impact of the lens barrel; it is worth mentioning that the hysteresis characteristic of the state change of the liquid damping medium makes it impossible for it to flow at a high speed instantly, thereby being able to delay and weaken the amplitude of the instantaneous movement of the lens to a certain extent, thereby realizing the buffering function; and the flow channel on the partition plate can realize a small flow of the liquid damping medium in the two chambers, leaving space for the movement of the lens barrel, so that the partition plate and the connected lens barrel can have a small movement, thereby absorbing the high-speed impact energy of the lens barrel, weakening the movement amplitude of the lens barrel, thereby avoiding large relative movement of the lens barrel and its internal inner lens group, ensuring the stability of the functional structure of the lens barrel, and reducing the risk of damage to the lens barrel. On the other hand, considering that the fluidity of the liquid damping medium is poor and the lens barrel cannot be actively reset, a reset member can be connected between the carrier and the lens barrel to generate a force that causes the lens barrel to reset when the lens barrel shifts relative to the carrier, so that after the lens barrel buffering is completed, it is gradually reset to ensure the position stability of the lens group in the lens barrel.
