[0035] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0036] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0037] This disclosure provides mid-frame components and electronic devices in some embodiments, which are applied to foldable screen electronic devices.

[0038] In related technologies, foldable screen electronic devices 1 are mainly divided into two usage scenarios: folding and unfolding. Foldable screen electronic devices 1 achieve folding or unfolding through a hinge structure 2. Figure 1 This is a schematic diagram of the structure of a foldable screen electronic device 1 in the related technology, such as... Figure 1 As shown, when the foldable screen electronic device 1 is folded, the hinge structure 2 is located on the hinge side. Figure 2This is a schematic diagram of a foldable screen electronic device 1 falling in the related technology, such as... Figure 2 As shown, since the hinge structure 2 protrudes from the hinge side, when the foldable screen electronic device 1 falls to the ground 3 from the hinge side, the hinge structure 2 will directly contact the ground 3 and be impacted. Figure 3 This is a schematic diagram of the hinge structure 2 of the foldable screen electronic device 1 before and after being impacted in the related technology, as shown below. Figure 3 As shown, the basic structure of the foldable screen electronic device 1 is that the screen 11 is attached to the hinge structure 2. After the hinge structure 2 is impacted, it will cause damage to the hinge structure 2, or the hinge structure 2 will squeeze the screen 11 inward, which will then cause damage to the screen 11.

[0039] In view of the above, some embodiments of this disclosure provide a mid-frame component and an electronic device. Figure 4 This is a structural schematic diagram of a mid-frame component according to some embodiments of the present disclosure. Figure 5 This is a schematic diagram illustrating a mid-frame component falling according to some embodiments of this disclosure. Figure 4 and Figure 5 As shown, the middle frame assembly includes: a middle frame body 4, a pivot structure 2, and a middle frame mechanism 5. The middle frame body 4 is folded or unfolded via the pivot structure 2, and when the middle frame body 4 is folded, a portion of the pivot structure 2 protrudes beyond the middle frame body 4. The middle frame mechanism 5 is connected to the middle frame body 4. When the middle frame body 4 is folded, the protruding portions of the middle frame mechanism 5 and the pivot structure 2 are located at the same end of the middle frame body 4, and the middle frame mechanism 5 protrudes beyond the middle frame body 4. The length of the middle frame mechanism 5 protruding beyond the middle frame body 4 is greater than or equal to the length of the pivot structure 2 protruding beyond the middle frame body 4.

[0040] By providing a mid-frame mechanism 5 on the pivot side of the mid-frame body 4 to protect the pivot structure 2, when the electronic device falls to the ground 3 on the pivot side, the mid-frame mechanism 5 directly contacts the ground 3, thereby reducing the risk of the pivot structure 2 being damaged by impact, and reducing the risk of the screen being damaged by the pivot structure 2 being squeezed after being impacted.

[0041] The mid-frame assembly, as the frame part of an electronic device, is used to support various components of the electronic device. One embodiment of the mid-frame assembly disclosed herein is suitable for an inward-folding screen electronic device, where the screen is located inside the mid-frame body 4 when the mid-frame body 4 is folded. When the mid-frame body 4 is folded, both the hinge structure 2 and the mid-frame mechanism 5 protrude from the mid-frame body 4 on the same side, and the length of the mid-frame mechanism 5 protruding from the mid-frame body 4 is greater than or equal to the length of the hinge structure 2 protruding from the mid-frame body 4. This ensures that in the event of a drop, the mid-frame mechanism 5 can contact the ground 3 first compared to the hinge structure 2, thereby reducing the risk of damage to the hinge structure 2 from impact, and reducing the risk of screen damage caused by the hinge structure 2 being compressed after impact.

[0042] In some embodiments, there are two or more middle frame mechanisms 5. The two or more middle frame mechanisms 5 are respectively located on both sides of the pivot structure 2 to enhance the protection of the pivot structure 2. The two or more middle frame mechanisms 5 are all fixedly connected to the middle frame body 4, and the two or more middle frame mechanisms 5 are staggered to avoid the protruding middle frame mechanism 5 affecting the middle frame body 4 when the middle frame body 4 is unfolded.

[0043] In some embodiments, the middle frame assembly further includes a transmission structure 6. The transmission structure 6 is connected to the middle frame mechanism 5, which is movably connected to the middle frame body 4. The transmission structure 6 is used to drive the middle frame mechanism 5 to protrude from the middle frame body 4 when the middle frame body 4 is folded, thereby protecting the transmission structure 6 when the middle frame body 4 is folded. And / or when the middle frame body 4 is unfolded, the transmission structure 6 is used to drive the middle frame mechanism 5 to retract into the middle frame body 4, to prevent the protruding middle frame mechanism 5 from affecting the middle frame body 4 when it is unfolded.

[0044] For example, the transmission structure 6 may include a motor and a sensor. The sensor is used to obtain the bending angle of the middle frame body 4, that is, to obtain whether the middle frame body 4 is in a folded or unfolded state, or whether the middle frame body 4 is about to be in a folded or unfolded state. Based on the data obtained by the sensor, the transmission structure 6 drives the middle frame mechanism 5, causing the middle frame mechanism 5 to protrude out of or retract into the middle frame body 4.

[0045] In some embodiments, the transmission structure 6 is hinged to the rotating shaft structure 2 and slidably connected to the middle frame body 4. During the folding or unfolding of the middle frame body 4 via the rotating shaft structure 2, the transmission mechanism is driven to move; that is, the transmission structure 6 slides relative to the middle frame body 4. This sliding motion of the transmission structure 6 drives the middle frame mechanism 5 to protrude from or retract into the middle frame body 4. In other words, the transmission structure 6 does not require an additional power source; the movement of the middle frame mechanism 5 can be achieved simply by the user operating the folding or unfolding of the middle frame body 4.

[0046] Figure 6 This is a cross-sectional view of a mid-frame assembly folded according to some embodiments of the present disclosure. Figure 7 This is a cross-sectional view of a mid-frame component when unfolded, according to some embodiments of the present disclosure. Figure 11 This is a schematic diagram illustrating the structure of a mid-frame component when unfolded, according to some embodiments of this disclosure. Figure 6 , Figure 7 and Figure 11As shown, in some embodiments, the middle frame body 4 includes a first middle frame 41 and a second middle frame 42. The first middle frame 41 and the second middle frame 42 are rotatably connected to the pivot structure 2, respectively. The first middle frame 41 has a first end 411, and the second middle frame 42 has a second end 421. When the middle frame body 4 is unfolded, the first end 411 and the second end 421 are opposite each other. The middle frame mechanism 5 is disposed at the first end 411 and / or the second end 421, so that when the middle frame body 4 is folded, the protruding middle frame mechanism 5 can protect the pivot structure 2, or when the middle frame body 4 is unfolded, the retracted middle frame mechanism 5 will not limit the first end 411 and the second end 421, thereby affecting the unfolding of the middle frame body 4.

[0047] In some embodiments, the middle frame mechanism 5 includes a first plate 51 and a second plate 52. The first plate 51 is disposed on the first middle frame 41, and the second plate 52 is disposed on the second middle frame 42. Figure 14 This is a schematic diagram of the structure of the first plate 51 shown according to some embodiments of the present disclosure, such as... Figure 6 , Figure 7 and Figure 14 As shown, the plane of the first plate 51 is parallel to the rotation axis of the first middle frame 41, so that the first plate 51 protrudes from one end of the first middle frame 41, which can protect the rotating shaft structure 2. The second plate 52 is a mirror image of the first plate 51, and the second plate 52 protrudes from one end of the second middle frame 42, which can protect the rotating shaft structure 2.

[0048] Figure 15 This is a schematic diagram of the structure of the first middle frame 41 according to some embodiments of the present disclosure. Figure 6 , Figure 7 and Figure 15 As shown, in some embodiments, the first middle frame 41 includes a first guide groove 412, and the first plate 51 is slidably connected to the first middle frame 41 via the first guide groove 412. The opening of the first guide groove 412 is located at the first end 411, allowing the first plate 51 to protrude from the first end 411 through the opening of the first guide groove 412. Furthermore, the second middle frame 42 includes a second guide groove 422, and the second plate 52 is slidably connected to the second middle frame 42 via the second guide groove 422, allowing the second plate 52 to protrude from the second end 421 through the opening of the second guide groove 422.

[0049] In some embodiments, the transmission structure 6 includes a first synchronizing rod 61 and a second synchronizing rod 62. The two ends of the first synchronizing rod 61 are a first rotating end 612 and a first sliding end 611, respectively. The first rotating end 612 is rotatably connected to the rotating shaft structure 2, and the first sliding end 611 is slidably connected to the first middle frame 41. The first sliding end 611 is used to drive the first plate 51 to slide, allowing the first plate 51 to protrude from or retract into the first end 411 through the opening of the first guide groove 412. The two ends of the second synchronizing rod 62 are a second rotating end 622 and a second sliding end 621, respectively. The second rotating end 622 is rotatably connected to the rotating shaft structure 2, and the second sliding end 621 is slidably connected to the second middle frame 42. The second sliding end 621 is used to drive the second plate 52 to slide, allowing the second plate 52 to protrude from or retract into the second end 421 through the opening of the second guide groove 422.

[0050] The first synchronizing rod 61 and the second synchronizing rod 62 are connected by the first rotating end 612 and the second rotating end 622, so that the first synchronizing rod 61 and the second synchronizing rod 62 remain synchronized during rotation. This ensures that the first middle frame 41 and the second middle frame 42 remain synchronized during folding or unfolding, and avoids uneven force on the screen 11 or mechanical jamming caused by asynchronous movement of the first middle frame 41 and the second middle frame 42.

[0051] For example, the first rotating end 612 and the second rotating end 622 can be connected by a gear set.

[0052] In some embodiments, such as Figure 7As shown, the first middle frame 41 includes a third guide groove 4131, and a first synchronizing rod 61 is located within the third guide groove 4131. The third guide groove 4131 and the first guide groove 412 are connected through a first clearance hole 4121. The first synchronizing rod 61 and the first plate 51 are fixedly connected through the first clearance hole 4121. During the folding or unfolding of the first middle frame 41 and the second middle frame 42, the first synchronizing rod 61 slides within the third guide groove 4131 and directly drives the first plate 51 located within the first guide groove 412 to slide through the first clearance hole 4121. Similarly, the second middle frame 42 includes a fourth guide groove 4231, and a second synchronizing rod 62 is located within the fourth guide groove 4231. The fourth guide groove 4231 and the second guide groove 422 are connected through a second clearance hole 4121. The second synchronizing rod 62 and the second plate 52 are fixedly connected through the second clearance hole 4121. During the folding or unfolding of the first middle frame 41 and the second middle frame 42, the second synchronizing rod 62 slides within the fourth guide groove 4231 and directly drives the second plate 52 located within the second guide groove 422 to slide through the second clearance hole 4121. This ensures that during the folding of the first middle frame 41 and the second middle frame 42, the first plate 51 and the second plate 52 protrude from the first end 411 and the second end 421 respectively, protecting the rotating shaft structure 2. During the unfolding of the first middle frame 41 and the second middle frame 42, the first plate 51 and the second plate 52 retract into the first end 411 and the second end 421 respectively, avoiding any impact on the unfolding process.

[0053] In some embodiments, the hinge structure 2 includes a hinge support 23, a first track rod 21, and a second track rod 22. The two ends of the first track rod 21 are hinged to the hinge support 23 and the first middle frame 41, respectively. The two ends of the second track rod 22 are hinged to the hinge support 23 and the second middle frame 42, respectively. The first track rod 21 and the second track rod 22 cooperate with the first synchronization rod 61 and the second synchronization rod 62 to guide the folding path of the first middle frame 41 and the second middle frame 42, i.e., guide the bending path of the screen, control the bending radius and shape of the screen during folding, and ensure that it moves along a preset trajectory, preventing damage to the screen due to excessive bending or localized compression.

[0054] Taking the mechanism composed of the pivot support 23, the first track rod 21, the first synchronizing rod 61, and the first middle frame 41 as an example, the first track rod 21 is hinged to both the pivot support 23 and the first middle frame 41, and the first synchronizing rod 61 is hinged to the pivot support 23 and slidably connected to the first middle frame 41. When the first middle frame 41 rotates around the pivot support 23, the position of the first synchronizing rod 61 changes. The sliding pair between the first synchronizing rod 61 and the first middle frame 41 is not self-locking. The first sliding end 611 of the first synchronizing rod 61 adjusts its position along the sliding direction to coordinate the movement and release the degree of freedom. That is, during the folding or unfolding process of the first middle frame 41, the first sliding end 611 of the first synchronizing rod 61 slides relative to the first middle frame 41 to drive the first plate 51 to slide. Similarly, during the folding or unfolding process of the second middle frame 42, the second sliding end 621 of the second synchronizing rod 62 slides relative to the second middle frame 42 to drive the second plate 52 to slide.

[0055] Figure 12 This is a schematic diagram of the structure of the first synchronizing rod 61 according to some embodiments of this disclosure. Figure 12 and Figure 7 As shown, the first synchronizing rod 61 has a first rotating end 612 and a first sliding end 611 at its two ends. The first rotating end 612 has a gear structure for meshing with the second rotating end 622. The first sliding end 611 matches the third guide groove 4131. The first synchronizing rod 61 also has a positioning pin 613, which is used to fix the first plate 51, allowing the first synchronizing rod 61 to drive the first plate 51 to slide. The structure of the second synchronizing rod 62 is mirror-symmetrical to that of the first synchronizing rod 61, and will not be described in detail here.

[0056] Figure 14 This is a structural schematic diagram of the first plate 51 shown according to some embodiments of the present disclosure. For example... Figure 12 , Figure 14 and Figure 15 As shown, the first plate 51 has a positioning hole 511, which matches the positioning pin 613 for fixing the first plate 51 and the first synchronizing rod 61. The positioning hole 511 and the positioning pin 613 are fixedly connected by a first clearance hole 4121, and the first clearance hole 4121 provides room for movement for the positioning hole 511 and the positioning pin 613.

[0057] Figure 13 This is a schematic diagram of the structure of the first fixing block 413 according to some embodiments of the present disclosure, such as... Figure 13 As shown, in some embodiments, the first middle frame 41 further includes a first fixing block 413, and the second middle frame 42 further includes a second fixing block 423. A third guide groove 4131 is located in the first fixing block 413, and a fourth guide groove 4231 is located in the second fixing block 423. Figure 7 , Figure 13and Figure 15 As shown, the first guide groove 412 is formed in the first middle frame 41, the third guide groove 4131 is formed in the first fixing block 413, and the first clearance hole 4121 is formed in the first fixing block 413 and communicates with the first guide groove 412 and the third guide groove 4131. After the first fixing block 413 is installed in the first middle frame 41, the first guide groove 412 and the third guide groove 4131 are connected through the first clearance hole 4121, so that the first synchronizing rod 61 can be connected to the first plate 51. The second fixing block 423 is similar, and will not be described in detail here.

[0058] Figure 9 This is a schematic diagram illustrating the structure of the pivot structure 2 and the transmission structure 6 when the middle frame assembly is unfolded, according to some embodiments of this disclosure. Figure 9 As shown in Figures 1 and 11, in some embodiments, the first middle frame 41 is hinged to the first track rod 21 via a first fixing block 413, and the second middle frame 42 is hinged to the second track rod 22 via a second fixing block 423. The first middle frame 41 has a threaded hole, and the first fixing block 413 is fixed to the first middle frame 41 by bolts. The second middle frame 42 has a threaded hole, and the second fixing block 423 is fixed to the second middle frame 42 by bolts. By connecting the first track rod 21 and the first synchronizing rod 61 to the first fixing block 413, with the first fixing block 413 detachably connected to the first middle frame 41, and connecting the second track rod 22 and the second synchronizing rod 62 to the second fixing block 423, with the second fixing block 423 detachably connected to the second middle frame 42, it is convenient to install the rotating shaft structure 2 and the transmission structure 6 onto the first middle frame 41 and the second middle frame 42.

[0059] Figure 8 This is a schematic diagram of the pivot structure 2 and transmission structure 6 of a mid-frame assembly when folded, according to some embodiments of the present disclosure. Figure 10 This is an exploded view of the rotating shaft structure 2 and the transmission structure 6 according to some embodiments of this disclosure. Figure 6 , Figure 8 and Figure 10 As shown, in some embodiments, the pivot structure 2 further includes a pivot cover 231. The pivot cover 231 is connected to the pivot support 23, and when the middle frame body 4 is folded, the pivot cover 231 covers the portion of the pivot structure 2 that protrudes from the middle frame body 4. The pivot cover 231, as part of the pivot support 23, is used to install the first track rod 21, the second track rod 22, the first synchronization rod 61, and the second synchronization rod 62, and provides protection for the pivot structure 2.

[0060] In some embodiments, the shaft structure 2 further includes a mounting plate 232. The mounting plate 232 is engaged with the shaft cover 231 to form a shaft support portion 23, which facilitates the installation of the first track rod 21, the second track rod 22, the first synchronization rod 61, and the second synchronization rod 62 on the shaft support portion 23.

[0061] According to some embodiments of this disclosure, an electronic device 700 is provided, including the mid-frame assembly described in any of the above embodiments. The electronic device 700 achieves folding and unfolding via the mid-frame assembly. When the electronic device 700 is folded, both the hinge structure 2 and the mid-frame mechanism 5 protrude from the mid-frame body 4 on the same side of the mid-frame body 4, and the length of the mid-frame mechanism 5 protruding from the mid-frame body 4 is greater than or equal to the length of the hinge structure 2 protruding from the mid-frame body 4. This ensures that in the event of a drop, the mid-frame assembly can contact the ground first compared to the hinge structure 2, thereby reducing the risk of damage to the hinge structure 2 from impact and reducing the risk of screen damage caused by the hinge structure 2 pressing against the screen.

[0072] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0073] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any of the associated listed items and any combination of any two or more; it should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "mounting," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral part; as a mechanical connection, an electrical connection, or a communicative connection; as a direct connection or an indirect connection through an intermediate medium; as a connection within two elements or an interaction between two elements, unless otherwise expressly limited. Those skilled in the art will understand the specific meaning of the above terms herein according to the specific circumstances.

[0074] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0075] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0076] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, a first component, part, region, layer, or section mentioned in the examples may also be referred to as a second component, part, region, layer, or section. 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 indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature.

[0077] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0078] In this description, "multiple" means at least two, referring to two or more, such as two, three, etc., unless otherwise explicitly specified. Other quantifiers are similar. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. Furthermore, unless otherwise specified or clearly indicated from the context, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more."

[0079] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any one of the related listed items and any combination of two or more; "and / or" describes the association relationship between related objects, indicating that three relationships may exist, for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Similarly, "at least one of..." includes any one of the related listed items and any combination of two or more.

[0080] Furthermore, the term "exemplary" is used herein to indicate that it serves as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term "exemplary" is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to indicate an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies A or B" is intended to indicate any of the natural inclusive permutations. That is, if X applies A; X applies B; or X applies both A and B, then applying A or B satisfies the condition under any of the foregoing instances.

[0081] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if it is not structurally equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in this disclosure, such terms are intended to be inclusive in a manner similar to the term “including.”

[0082] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.

[0083] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
