Abstract
Description
Technical Field
[0001] This utility model relates to the field of imaging equipment technology, specifically to a buffer component, a camera module, and an electronic device. Background Technology
[0002] A typical camera module includes a base and a movable mount. Optical components are mounted on the movable mount and move up and down and horizontally relative to the base along with the movable mount to perform focusing and image stabilization. As lenses become heavier, the movement of the movable mount within the housing can easily produce abnormal noises.
[0003] Chinese patent document CN113315888A discloses a camera module, including: a cover member, with a plurality of buffer members protruding in an upward direction formed in the upper part of the cover member, wherein one or more buffer members can reduce the impact caused by collision between a movable body and a shield. In other words, this solution solves the problem of upward collision of the movable body by setting buffer members on the cover member.
[0004] However, with the above solution, the small size of the camera module makes it difficult to assemble the buffer component on the cover component, resulting in low yield and high cost. Utility Model Content
[0005] In view of this, the present invention provides a buffer component, a camera module, and an electronic device to solve the problem of difficult assembly of the buffer component.
[0006] This utility model provides a buffer component, including: a body part and a buffer part, wherein the buffer part and the body part are integrally formed, the buffer part has a deformable section and a protrusion connected to the deformable section, the protrusion at least partially protrudes from the surface of the body part, and the surface of the body part forms a clearance groove on the back side of the protrusion.
[0007] This invention solves the assembly difficulties of the buffer section by integrally molding the buffer part with the main body. During use, when an external impact force acts on the protrusion of the buffer member, the deformable section absorbs energy through its own deformation, thereby reducing the impact force transmitted to the main body and its connected components. The recessed groove formed on the main body provides space for the deformation of the protrusion. When the protrusion is subjected to external force, the recessed groove allows the protrusion to recess into the groove, enabling it to absorb energy.
[0008] Optionally, the buffer portion is formed on the side of the main body. Since the movement of the movable seat within the base includes not only vertical movement but also horizontal movement to prevent shaking, by forming the buffer portion on the side of the main body, the protrusion of the buffer portion can abut against the inner wall of the housing, thereby avoiding or reducing the horizontal shaking of the movable seat.
[0009] The buffer section has multiple buffer sections spaced apart on the side of the main body. The spaced-apart buffer sections make the horizontal force more evenly distributed. The protrusion of each buffer section shares a portion of the horizontal external force, avoiding excessive force at a single point.
[0010] Optionally, the buffer section has at least two spaced-apart portions on each side of the main body. This arrangement allows for a more even distribution of external forces acting on the movable seat. This avoids excessive localized stress and extends the service life of the buffer section and the entire movable seat structure.
[0011] Optionally, the deformable segment is a plate structure, with one end connected to one end of the recessed groove and the other end connected to the protrusion. The plate-structured deformable segment possesses excellent flexibility and elastic deformation capability. When subjected to external impact, the plate-shaped deformable segment can effectively absorb energy through its own bending deformation. Specifically, when an external force acts on the protrusion, the protrusion transmits the force to the deformable segment, which utilizes its plate structure characteristics to undergo bending deformation, converting the impact energy into its own elastic potential energy, thereby mitigating the impact force on the main body and connected components.
[0012] Optionally, the thickness of the deformable segment gradually decreases towards the protrusion. With this configuration, when an external force is applied to the protrusion, the thinner end deforms more easily, responding to the impact force more quickly and beginning to absorb energy. As the impact force continues, the deformation gradually propagates towards the thicker end, achieving orderly and sufficient deformation of the entire deformable segment.
[0013] Optionally, the deformable segment is a plate structure, with one end connected to one end of the relief groove and the other end connected to the other end of the relief groove. The protrusion is located in the middle of the deformable segment. With this configuration, since both ends of the deformable segment are connected, it can provide stronger elastic potential energy, thereby providing higher impact resistance.
[0014] Optionally, the buffer section includes a first buffer section and a second buffer section stacked together, with the first buffer section and the second buffer section connected to the same end of the relief groove. This arrangement provides a multi-stage buffering effect through the stacked first and second buffer sections. When an external force is applied to the buffer section, the outer buffer section (the first buffer section) initially absorbs part of the impact force and begins to deform and absorb energy. As the impact force continues, after the first buffer section deforms to a certain extent, the inner second buffer section begins to function, further absorbing the remaining impact force. This multi-stage buffering method can more effectively cope with impact forces of varying intensities.
[0015] Optionally, the buffer section includes a first buffer section and a second buffer section stacked together. The first buffer section is connected to one end of the relief groove, and the second buffer section is connected to the other end of the relief groove. With this configuration, since the two buffer sections are connected to the two ends of the relief groove respectively, stress can be more evenly distributed across the relief groove and the main body. When external force is applied to the buffer section, stress concentration at one end or in a localized area is avoided, thereby enhancing the stability and reliability of the entire buffer structure.
[0016] Optionally, the deformable segment is a plate structure, with one end connected to one end of the relief groove, and the other end adapted to overlap with the other end of the relief groove. The protrusion is located in the middle of the deformable segment. Specifically, in the free state, the end of the deformable segment that overlaps with the other end of the relief groove has a gap between it and the main body. This configuration achieves a phased buffering mechanism. When the impact force is small, the overlap remains spaced, and the plate structure primarily exhibits elastic bending. The plate structure has good elastic deformation capability, enabling it to absorb energy through a large degree of elastic bending, effectively coping with small impact forces. When the impact force increases, the overlap occurs. This action changes the structure and mechanical properties of the deformable segment, increasing the effective buffering area and deformation mode. The overlap at the joint allows the deformable segment to withstand greater impact forces and further absorb energy.
[0017] This utility model also provides a camera module, including: a housing and a buffer member as described in any of the above embodiments. The housing has a base and a movable base. The movable base can move horizontally on the base. An optical device is connected to the movable base. The optical device moves synchronously with the movable base. The buffer member is connected to the movable base.
[0018] The camera module in this solution has all the advantages due to the use of the aforementioned buffer components.
[0019] This utility model also provides an electronic device, including: the camera module described in the above solution. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0039] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0040] like Figure 1 , Figure 2As shown, this is a specific implementation of the camera module provided in this embodiment, including: a housing, the housing having a base and a movable base, the movable base being movable on the base in a horizontal direction, an optical device being connected to the movable base, and the optical device moving synchronously with the movable base.
[0041] like Figure 2 , Figure 3 As shown, a buffer member is connected to the movable seat. The buffer member includes a body and a buffer portion, which are integrally formed with the body. It should be noted that in this embodiment, the movable seat serves as the body of the buffer member; that is, the buffer portion is formed on the movable seat.
[0042] The technical solution provided in this embodiment avoids the subsequent assembly process of the buffer part by integrally molding the buffer part with the main body, thereby solving the problem of difficult assembly of the buffer part. In use, when an external impact force acts on the protrusion of the buffer member, the deformable section absorbs energy through its own deformation, thereby reducing the impact force transmitted to the main body and its connected components.
[0043] like Figure 3 As shown, in some embodiments, the buffer portion has a deformable section and a protrusion connected to the deformable section. The protrusion at least partially protrudes from the surface of the body portion, and a recessed groove is formed on the back side of the protrusion on the surface of the body portion. The recessed groove formed on the body portion provides space for the deformation of the protrusion. When the protrusion is subjected to an external force, the recessed groove allows the protrusion to recess into the groove, enabling the protrusion to absorb energy.
[0044] like Figure 3 As shown, in this embodiment, the buffer portion is formed on the side of the main body. Since the movement of the movable seat within the base includes not only vertical movement but also horizontal movement to prevent shaking, by forming the buffer portion on the side of the main body, the protrusion of the buffer portion can abut against the inner wall of the housing, thereby avoiding or reducing the horizontal shaking of the movable seat.
[0045] like Figure 3 As shown in this embodiment, the buffer portion has multiple buffer portions spaced apart on the side of the main body. The spaced-apart buffer portions make the force distribution in the horizontal direction more uniform. The protrusion of each buffer portion shares a portion of the horizontal external force, avoiding excessive force at a single point.
[0046] like Figure 3 As shown, in this embodiment, at least two buffer sections are spaced apart on each side of the main body. This arrangement allows for a more even distribution of external forces acting on the movable seat. This avoids excessive localized stress and extends the service life of the buffer sections and the entire movable seat structure.
[0047] like Figure 3 As shown, in this embodiment, the deformable segment is a plate structure. One end of the deformable segment is connected to one end of the clearance groove, and the other end of the deformable segment is connected to the protrusion. The plate-structured deformable segment possesses excellent flexibility and elastic deformation capability. When subjected to external impact, the plate-shaped deformable segment can effectively absorb energy through its own bending deformation. Specifically, when an external force acts on the protrusion, the protrusion transmits the force to the deformable segment. The deformable segment utilizes its plate structure characteristics to undergo bending deformation, converting the impact energy into its own elastic potential energy, thereby mitigating the impact force on the main body and connected components.
[0048] like Figure 4 As shown, line segment one represents the buffer characteristic curve of this embodiment. The horizontal axis represents the movement stroke of the buffer part in mm, and the vertical axis represents the magnitude of the force provided by the buffer member in G. As can be seen from line segment one in the figure, the buffer member of this embodiment can provide a continuous and relatively stable buffering force during use.
[0049] like Figure 5 As shown, in some embodiments, the thickness of the deformable segment gradually decreases towards the protrusion. This configuration allows the thinner end to deform more easily when an external force is applied to the protrusion, enabling it to respond to impact forces more quickly and begin absorbing energy. As the impact force continues, the deformation gradually propagates towards the thicker end, resulting in orderly and sufficient deformation of the entire deformable segment.
[0050] like Figure 6 As shown, line segment two represents the buffer characteristic curve of this embodiment. The horizontal axis represents the movement stroke of the buffer part in mm, and the vertical axis represents the magnitude of the force provided by the buffer member in G. It can be seen from line segment two in the figure that the buffer member of this embodiment can provide a continuous, relatively stable, and large buffering force during use.
[0051] like Figure 7 As shown, in some embodiments, one end of the deformable segment is connected to one end of the relief groove, and the other end of the deformable segment is connected to the other end of the relief groove, with the protrusion disposed in the middle of the deformable segment. With this configuration, since both ends of the deformable segment are connected, the deformable segment can provide stronger elastic potential energy, thereby providing higher impact resistance.
[0052] like Figure 8 As shown, line segment three represents the buffer characteristic curve of this embodiment. The horizontal axis represents the movement stroke of the buffer part in mm, and the vertical axis represents the magnitude of the force provided by the buffer member in G. As can be seen from line segment three in the figure, the buffer member of this embodiment can provide a continuous and relatively stable large buffer force during use.
[0053] like Figure 9 As shown, in some embodiments, the buffer section includes a first buffer section and a second buffer section stacked together, with the first buffer section and the second buffer section connected to the same end of the relief groove. This arrangement provides a multi-stage buffering effect through the stacked first and second buffer sections. When an external force is applied to the buffer section, the outer buffer section (the first buffer section) first bears part of the impact force and begins to deform and absorb energy. As the impact force continues, after the first buffer section deforms to a certain extent, the inner second buffer section begins to function, further absorbing the remaining impact force. This multi-stage buffering method can more effectively cope with impact forces of different intensities.
[0054] like Figure 10 As shown, in some embodiments, the buffer section includes a first buffer section and a second buffer section stacked together. The first buffer section is connected to one end of the relief groove, and the second buffer section is connected to the other end of the relief groove. This arrangement, with the two buffer sections connected to opposite ends of the relief groove, allows stress to be more evenly distributed across the relief groove and the main body. When external forces act on the buffer section, stress concentration at one end or in a localized area is avoided, thereby enhancing the stability and reliability of the entire buffer structure.
[0055] like Figure 11 As shown in the figure, line segment four represents the buffer characteristic curves of the two embodiments described above. The horizontal axis represents the travel distance of the buffer part in mm, and the vertical axis represents the magnitude of the force provided by the buffer member in G. As can be seen from line segment four in the figure, the buffer member of the two embodiments described above can provide two stages of buffering force during use. In the initial stage of buffering, it provides a gentle and smaller buffering force, while in the second stage, it can provide a larger buffering force.
[0056] like Figure 12 As shown, in some embodiments, one end of the deformable segment is connected to one end of the relief groove, and the other end of the deformable segment is adapted to overlap with the other end of the relief groove. The protrusion is located in the middle of the deformable segment. Specifically, in the free state, the end of the deformable segment that overlaps with the other end of the relief groove has a gap between it and the main body. This arrangement realizes a phased buffering mechanism. When the impact force is small, the overlap remains spaced, and the plate structure mainly uses elastic bending. The plate structure has good elastic deformation capability and can absorb energy through a large degree of elastic bending, effectively coping with small impact forces. When the impact force increases, the overlap occurs. This action changes the structure and mechanical properties of the deformable segment, increasing the effective buffering area and deformation mode. The overlap at the joint allows the deformable segment to withstand greater impact forces and further absorb energy.
[0057] like Figure 13 As shown, line segment five represents the buffer characteristic curve of this embodiment. Its horizontal axis represents the movement stroke of the buffer part in mm, and its vertical axis represents the magnitude of the force provided by the buffer member in G. As can be seen from line segment five in the figure, the buffer member of the above embodiment can provide two stages of buffering force during use. In the initial stage of buffering, it provides a gentle and smaller buffering force, while in the second stage, it can provide a much larger buffering force.
[0058] An embodiment of this utility model also provides an electronic device, including the camera module described above. Specifically, the electronic device may include a mobile phone, a camera, etc.
[0059] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
