In a specific working process, please refer to fig. 6 again, when the middle frame 100 is deformed by the crying face (a display screen is disposed on one side of the middle frame 100, and the two opposite ends of the middle frame 100 are bent toward the direction close to the display screen, which is called as the crying face deformation), the telescopic mechanism 200 is disposed on one side of the middle frame 100 away from the display screen, and the telescopic mechanism 200 is adjusted to contract, so that one side of the middle frame 100 away from the display screen is pulled, so that the two opposite ends of the middle frame 100 are bent toward the direction away from the display screen, thereby counteracting the crying face deformation of the middle frame 100, and finally making the deformation of the middle frame 100 smaller. Of course, the telescopic mechanism 200 may also be disposed on one side of the middle frame 100 close to the display screen, and at this time, by adjusting the extension of the telescopic mechanism 200, one side of the middle frame 100 close to the display screen is pressed, so that the two ends of the middle frame 100, which are opposite to each other, are bent toward the direction away from the display screen, and further the crying face deformation of the middle frame 100 can be offset.

Of course, the telescopic mechanism 200 may also be disposed on one side of the middle frame 100 close to the display screen, and at this time, by adjusting the telescopic mechanism 200 to contract, one side of the middle frame 100 close to the display screen is pulled, so that the two ends of the middle frame 100, which are opposite to each other, are bent toward the direction close to the display screen, and further, the crying face deformation of the middle frame 100 can be offset.

When telescopic machanism 200 is flexible, center 100 can be along with telescopic machanism 200 flexible and crooked towards the first direction, when the crooked direction of first direction and center 100 is opposite, the bending deformation of center 100 produced in the forming process can be offset to the bending deformation this moment, thereby can prevent that great deformation from appearing in center 100, and then avoid center 100 and display screen bonding problem to appear in the assembling process, finally can improve electronic equipment's reliability, promote user experience.
As described above, the telescopic mechanism 200 may be of various types, such as a hydraulic telescopic rod or a pneumatic telescopic rod, and the hydraulic telescopic rod or the pneumatic telescopic rod has a complicated structure and a high cost, so that the hydraulic telescopic rod or the pneumatic telescopic rod is applied to the middle frame 100 with a poor effect, and the cost of the housing is high. Based on this, in an alternative embodiment, the telescoping mechanism 200 may include a main body portion 230, a first moving portion 240, and a second moving portion 250; the main body 230 may have a first threaded portion and a second threaded portion, and the first threaded portion and the second threaded portion have opposite rotation directions, for example, the first threaded portion is provided with left-handed threads and the second threaded portion is provided with right-handed threads; or the first thread part is provided with a right-handed thread, and the second thread part is provided with a left-handed thread.
Both the first moving portion 240 and the second moving portion 250 may be provided with a threaded hole, the threaded hole of the first moving portion 240 is in threaded engagement with the first threaded portion, and the threaded hole of the second moving portion 250 is in threaded engagement with the second threaded portion, of course, the threaded hole of the first moving portion 240 may also be in threaded engagement with the second threaded portion, and the threaded hole of the second moving portion 250 is in threaded engagement with the first threaded portion. The first moving part 240 may form the first matching part 210, and the second moving part 250 may form the second matching part 220, but of course, the first moving part 240 may also form the second matching part 220, and the second moving part 250 may form the first matching part 210. The first moving part 240 and the second moving part 250 may approach or separate from each other with the rotation of the main body part 230, the first moving part 240 and the second moving part 250 approach each other with the rotation of the main body part 230, that is, a process of contracting the retracting mechanism 200, and the first moving part 240 and the second moving part 250 separate from each other with the rotation of the main body part 230, that is, a process of extending the retracting mechanism 200. The telescopic mechanism 200 has a simple structure and reliable telescopic motion, and the main body 230, the first moving part 240 and the second moving part 250 are convenient to manufacture and have low cost, so that the telescopic mechanism 200 has a good effect when applied to the middle frame 100 and has low cost of the shell.
Specifically, the shape of the main body 230, the first moving part 240, and the second moving part 250 may be various, for example, the shape of the main body 230 may be a rod shape, and the shape of the first moving part 240 and the second moving part 250 may be a nut shape, and the shape of the main body 230, the first moving part 240, and the second moving part 250 is not limited in the embodiment of the present invention. Further, the body part 230 may be a screw because the structure of the screw is simpler and the manufacturing is convenient.
The first moving portion 240 of the telescoping mechanism 200 needs to be in limit fit with the first limit portion 120, and the second moving portion 250 of the telescoping mechanism 200 needs to be in limit fit with the second limit portion 130, and the limit fit may be generally performed in various manners, for example, the first moving portion 240 is bonded or riveted with the first limit portion 120, and the second moving portion 250 is bonded or riveted with the second limit portion 130. Optionally, both the first limiting part 120 and the second limiting part 130 can be limiting grooves 121, both the first moving part 240 and the second moving part 250 can be provided with limiting convex parts 241, the limiting convex parts 241 are in limiting fit with the limiting grooves 121 in the telescopic direction of the telescopic mechanism 200, the limiting fit mode is easy to operate, and the first moving part 240 and the first limiting part 120 are made to be detachable and connected, both the second moving part 250 and the second limiting part 130 can be made to be convenient for installation personnel to install, and meanwhile, in the process of adjusting the telescopic mechanism 200 to be telescopic, if the telescopic mechanism 200 is damaged, the installation personnel can conveniently and quickly replace the telescopic mechanism 200, and the working efficiency is improved.
The telescopic mechanism 200 can transmit force to the middle frame 100 through the limit fit between the first moving portion 240 and the first limit portion 120 and the limit fit between the second moving portion 250 and the second limit portion 130, and particularly, when the transmitted force is large, the limit fit between the first moving portion 240 and the first limit portion 120 or the limit fit between the second moving portion 250 and the second limit portion 130 may fail, so that the telescopic mechanism 200 is difficult or incapable of transmitting the force to the middle frame 100, and further the deformation of the middle frame 100 is difficult to offset, so that the deformation of the middle frame 100 is large.
Based on this, in an alternative embodiment, the number of the limiting grooves 121 of the first limiting part 120 and the number of the limiting grooves 121 of the second limiting part 130 may be multiple, and the number of the limiting protrusions 241 of the first moving part 240 and the number of the limiting protrusions 241 of the second moving part 250 may be multiple; and the plurality of limiting convex portions 241 of the first moving portion 240 are in one-to-one limiting fit with the plurality of limiting grooves 121 of the first limiting portion 120, the plurality of limiting convex portions 241 of the second moving portion 250 are in one-to-one limiting fit with the plurality of limiting grooves 121 of the second limiting portion 130, so that the strength of the limiting fit between the first moving portion 240 and the first limiting portion 120 and the strength of the limiting fit between the second moving portion 250 and the second limiting portion 130 are improved, the limiting failure is prevented, the telescopic mechanism 200 can reliably transmit force to the middle frame 100, further the deformation of the middle frame 100 is offset, the deformation of the middle frame 100 is smaller, and the user experience is finally improved.
In the telescopic mechanism 200 having the above structure, an installer needs to manually rotate the main body 230 during telescopic movement, and in order to facilitate the installer to rotate the main body 230, an anti-slip groove may be formed on an outer surface of the main body 230, or an operation protrusion may be formed on an outer surface of the main body 230, so that the installer can manually rotate the main body 230, thereby allowing the telescopic mechanism 200 to perform telescopic movement. However, the installation space 100 may be small, resulting in a small space for an installer to manually operate, and at the same time, a force for the installer to rotate the main body part 230 by hand is small, resulting in difficulty in the installer to rotate the main body part 230. Based on this, in an alternative embodiment, a plurality of driving connection holes 260 may be opened on the main body portion 230 at a position between the first thread portion and the second thread portion, and the plurality of driving connection holes 260 are arranged at intervals in the rotation direction of the main body portion 230. Under this condition, the installer can use tools to rotate the main body part 230, and can select the driving connection hole 260 which is easy to control in the control process, so that the installer can conveniently drive the main body part 230 to rotate, and further, the installer can hardly be limited by the size of the installation space 100, and meanwhile, the installer can apply a large rotating force through tools, so that the installer can easily rotate the main body part 230, and further, the installer can conveniently adjust the deformation of the middle frame 100, and the deformation of the middle frame 100 is small.
Further, the plurality of driving connection holes 260 may be arranged at intervals in the telescopic direction. When the plurality of driving connection holes 260 are disposed at the same position in the telescopic direction, stress concentration is caused at the same portion, and the strength is low, and an installer may twist off the main body 230 when rotating the main body, so that when the plurality of driving connection holes 260 are arranged at intervals in the telescopic direction, the above-mentioned situation can be avoided, thereby improving the reliability of the telescopic mechanism 200.
In order to further improve the strength of the main body portion 230, so that the reliability of the telescopic mechanism 200 is higher, in an alternative embodiment, the main body portion 230 may be a screw, and the main body portion 230 may include a first section, an intermediate section and a second section, the first threaded portion is located in the first section, the second threaded portion is located in the second section, in the telescopic direction of the telescopic mechanism 200, the projection area of the intermediate section is larger than that of the first section, and the projection area of the intermediate section is larger than that of the second section, so that the middle portion of the main body portion 230 is thicker, and the strength of the main body portion 230 can be further improved, so that the reliability of the telescopic mechanism 200 is higher.
Further, all be provided with the toper changeover portion between interlude and the first section and between interlude and the second section, avoid appearing the condition of shape sudden change between interlude and the first section and between interlude and the second section to can prevent to appear stress concentration's phenomenon between interlude and the first section and between interlude and the second section, and then can improve main part 230's intensity.
Specifically, the plurality of driving connection holes 260 may be through holes, and when an installer rotates the main body part 230 using a tool, the tool needs to be inserted into the driving connection holes 260, and there are many contact portions between the through holes and the tool, so that the tool can be prevented from falling out of the driving connection holes 260, and meanwhile, when the tool is inserted into the through holes to rotate the main body part 230, the driving force applied to the circumferential direction of the main body part 230 by the installer is uniform, so that the installer can rotate the main body part 230 more easily.
In an embodiment of the present invention, the telescopic mechanism 200 can achieve an adjusting effect on the deformation of the middle frame 100 through telescopic movement, and in order to further enhance the adjusting degree of the deformation of the middle frame 100, in an alternative embodiment, a plurality of installation spaces 110 may be formed in the thickness direction of the middle frame 100, and the number of the telescopic mechanisms 200 may be multiple, and the plurality of telescopic mechanisms 200 are correspondingly arranged in the plurality of installation spaces 110 one to one. In this case, the plurality of telescopic mechanisms 200 adjust the deformation of the center frame 100 together, and the degree of adjustment of the deformation of the center frame 100 can be certainly enhanced, so that the deformation of the center frame 100 can be made small.
When the middle frame 100 is bent and deformed in the length direction, optionally, a plurality of installation spaces 110 may be opened in the length direction of the middle frame 100, and the number of the telescopic mechanisms 200 may be plural, and the plurality of telescopic mechanisms 200 are disposed in the plurality of installation spaces 110 in a one-to-one correspondence. Similarly, this way, the bending deformation existing in the length direction of the middle frame 100 can be adjusted for the bending deformation existing in the length direction of the middle frame 100.
Similarly, when the middle frame 100 has bending deformation in the width direction, a plurality of installation spaces 110 may be opened in the width direction of the middle frame 100, and the number of the telescopic mechanisms 200 may be plural, and the plurality of telescopic mechanisms 200 are disposed in the plurality of installation spaces 110 in a one-to-one correspondence, in this way, the bending deformation in the width direction of the middle frame 100 can be adjusted according to the bending deformation in the width direction of the middle frame 100.
Meanwhile, in the above two modes, the adjustment degree of the deformation of the middle frame 100 can be further strengthened by the plurality of telescopic mechanisms 200, so that the deformation of the middle frame 100 can be reduced. The thickness direction of the middle frame 100 is a direction from one side close to the display screen to the other side of the middle frame 100, the length direction of the middle frame 100 is an extending direction of a longer side of the middle frame 100, and the width direction of the middle frame 100 is an extending direction of a shorter side of the middle frame 100, and is different from the thickness direction of the middle frame 100.
After the deformation of the middle frame 100 is adjusted by the telescopic movement of the telescopic mechanism 200, it is necessary to keep the telescopic mechanism 200 continuously maintained in the extended state or the contracted state. Based on this, in an alternative embodiment, the installation space 110 may have an operation opening, the housing may further include a filling portion that is filled into the installation space 110 through the operation opening, and the filling portion at least partially blocks the operation opening. The filling part can seal the telescoping mechanism 200 and prevent the telescoping mechanism 200 from contracting or extending, so that the rigidity and strength of the middle frame 100 after deformation adjustment are difficult to lose, the middle frame 100 can be kept in a state after deformation adjustment, secondary deformation of the middle frame 100 is prevented, and the shape stability of the middle frame 100 is improved. Specifically, the filling portion may be rubber, glue, or the like, which is not limited in the embodiment of the present invention.
