All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The support frame and the electronic device provided in the embodiments of the present application are described in detail below with reference to fig. 1 to 12 through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 8, the electronic apparatus disclosed in the embodiment of the present invention includes a first housing 100, a second housing 200, a support plate 300, a transmission assembly 400, and a screen 600.
The first housing 100 and the second housing 200 may form the accommodating chamber 110, the second housing 200 is slidably coupled with the first housing 100, and the screen 600 is disposed on the first housing 100 and the second housing 200, so that the display area of the screen 600 may be increased in a case where the first housing 100 and the second housing 200 are spaced apart from each other, and the display area of the screen 600 may be reduced in a case where the first housing 100 and the second housing 200 are spaced apart from each other. Alternatively, the first housing 100 has an installation space, and one side of the first housing 100 adjacent to the second housing 200 may be provided with an opening such that at least a portion of the second housing 200 may be retracted into the installation space from the opening. During the relative sliding of the first housing 100 and the second housing 200, the second housing 200 may extend or retract from the opening into the installation space of the first housing 100 at least partially.
The support plate 300 and the transmission assembly 400 may be disposed in the receiving chamber 110. The first housing 100 and/or the second housing 200 may provide a mounting basis for the support plate 300 and the transmission assembly 400. Alternatively, the support plate 300 may be disposed on the second housing 200, and the support plate 300 may slide with the second housing 200 relative to the first housing 100 during the relative sliding of the first housing 100 and the second housing 200.
The transmission assembly 400 may include a cam 410 and a transmission member 430, the cam 410 being rotatably provided to the second housing 200. The transmission member 430 is fixedly connected with the first housing 100, the transmission member 430 is connected with the cam 410, the cam 410 is connected with the support plate 300, and in the process of moving the second housing 200 and the first housing 100, the transmission member 430 drives the cam 410 to rotate, and the cam 410 drives the support plate 300 to move between the first position and the second position. With the support plate 300 in the first position, the support plate 300 abuts against the screen 600 to support the screen 600. With the support plate 300 in the second position, the support plate 300 is retracted to the accommodating chamber 110.
In the above embodiment, the driving assembly 400 may drive the support plate 300 to move between the first position and the second position during the relative movement of the first housing 100 and the second housing 200, so that the movement of widening the display area of the screen 600 and the movement of the support plate 300 relative to the second housing 200 may be completed synchronously, thereby avoiding the switching movement of the support plate 300 between the first position and the second position, prolonging the preparation time required for widening the display area of the screen 600 for the electronic device, reducing the waiting of the user, and improving the user experience.
Specifically, in the case where it is necessary to widen the area of the display area of the screen 600, the first and second housings 100 and 200 may be driven away from each other, so that the display area of the screen 600 increases. In the process that the first casing 100 and the second casing 200 are far away from each other, the first casing 100 and the second casing 200 drive the support plate 300 to switch from the second position to the first position through the transmission assembly 400, that is, the support plate 300 moves to one side close to the screen 600, so that the support plate 300 can be supported below the screen 600 after the screen 600 is widened, and further collapse of the screen 600 after stress is avoided. In the case where it is necessary to reduce the area of the display area of the screen 600, the first and second housings 100 and 200 may be driven to approach each other so that the display area of the screen 600 is reduced. In the process that the first housing 100 and the second housing 200 approach each other, the first housing 100 and the second housing 200 drive the support plate 300 to switch from the first position to the second position through the transmission assembly 400, that is, the support plate 300 moves away from the screen 600, so that the support plate 300 can retract into the accommodating cavity 110.
It should be noted that, the electronic device in the above embodiment may drive the first housing 100 and the second housing 200 to relatively move through the driving mechanism, and may also manually operate the first housing 100 and the second housing 200 to relatively move. The embodiment of the present application is not limited to a specific manner of driving the first housing 100 and the second housing 200 to relatively move.
Optionally, at least one of the first housing 100 and the second housing 200 is slidably engaged with the screen 600, so that the screen 600 can slide along the surface of the first housing 100 or the second housing 200, thereby increasing or decreasing the area of the display surface of the screen 600. Optionally, at least a portion of the screen 600 may be slid from the first side of the electronic device to the second side of the electronic device during the process of moving the first housing 100 and the second housing 200 away from each other, thereby increasing the area of the screen 600 on the second side of the electronic device. The first side and the second side may be opposite sides in the electronic device. During the approaching of the first and second housings 100 and 200 to each other, at least part of the screen 600 may be slid from the second side of the electronic device to the first side of the electronic device, thereby reducing the area of the screen 600 at the second side of the electronic device.
There are many ways in which the screen 600 may be widened, for example, an increase or decrease in the display area of the screen 600 may also be achieved by crimping on a scroll. The specific manner in which the display area of the screen 600 is increased or decreased is not limited in the present application.
In an alternative embodiment, the number of support plates 300 is two. The two support plates 300 may be located at the first side and the second side of the second housing 200, respectively. The first side and the second side of the second housing 200 are opposite. Both support plates 300 are connected to the first housing 100 or the second housing 200 through the transmission assembly 400. In this embodiment, both sides of the second housing 200 may be supported by using two support plates 300 in a state where the first housing 100 and the second housing 200 are away from each other. In the case where the screens 600 are provided on both sides of the electronic device, the screens 600 located on both sides of the electronic device can be effectively supported. In the case that the electronic device has only the single-side setting screen 600, the flatness of one side of the second housing 200 facing away from the screen 600 can be ensured by the support plate 300, so that the fingers holding the electronic device are prevented from being depressed in the second housing 200, and the comfort level of holding the electronic device by a user is improved.
Referring to fig. 4 and 5, the transmission assembly 400 may further include a push rod 420, a first end of the push rod 420 is connected to the cam 410, a second end of the push rod 420 is connected to the support plate 300, and the cam 410 moves the support plate 300 between the first position and the second position by the push rod 420. In this embodiment, the push rod 420 may provide support for the support plate 300 on the one hand. On the other hand, through the transmission of the push rod 420, the friction between the edge of the cam 410 and the support plate 300 can be avoided, so that the support plate 300 slides along the screen 600, and the support plate 300 can be better spliced with the first casing 100 and/or the second casing 200. Alternatively, the push rod 420 may be slidably disposed within the receiving chamber 110. Specifically, a sliding groove or a sliding hole in sliding fit with the push rod 420 may be disposed in the accommodating cavity 110, so that the push rod 420 may move along the sliding groove or the sliding hole, thereby improving the stability of the movement of the push rod 420.
Referring to fig. 8 to 12, the cam 410 may be provided with a guide slot 411. The push rod 420 may be provided with a sliding portion 421. The push rod 420 may be supported by the guide slot 411 through a sliding portion 421, and the sliding portion 421 is slidably engaged with the guide slot 411. The push rod 420 is supported on the guide slot 411 through the sliding portion 421, so that the cam 410 can push or pull the push rod 420, that is, the cam 410 can apply two opposite forces to the push rod 420, so that the cam 410 can drive the support plate 300 to reciprocate between the first position and the second position through the push rod 420. Referring to fig. 11, the guide slot 411 may be disposed along an edge of the cam 410, and the first end of the push rod 420 is at least partially located in the guide slot 411, so that the first end of the push rod 420 may be far away from or near to the rotation axis of the cam 410 along the guide slot 411, thereby driving the support plate 300 to reciprocate.
In the above embodiment, the cam 410 rotates to drive the push rod 420 to move, and the push rod 420 is used to drive the support plate 300 to switch between the first position and the second position. Alternatively, when the support plate 300 is located at the first position, the distance between the first end of the push rod 420 and the rotation axis of the cam 410 is maximized, and thus, the cam 410 can rotate clockwise or counterclockwise to drive the support plate 300 to move from the first position to the second position through the push rod 420. Therefore, the cam 410 is utilized to drive the push rod 420 to move, so as to effectively control the movement range of the push rod 420, and further avoid damage to the screen 600 due to excessive displacement of the push rod 420 pushing the support plate 300 to move.
Referring to fig. 11 and 12, the first end of the push rod 420 may be provided with a first leg 422 and a second leg 423 at a distance. The first leg 422 and the second leg 423 may each be provided with a sliding portion 421. The cam 410 is at least partially positioned in a gap between the first leg 422 and the second leg 423, guide slots 411 are provided on both sides of the cam 410, and sliding portions 421 on the first leg 422 and the second leg 423 are slidably engaged with the guide slots 411 on both sides of the cam 410, respectively. Alternatively, the sliding portion 421 provided at the first leg 422 protrudes toward a side of the first leg 422 near the cam 410, so that the sliding portion 421 provided at the first leg 422 may be at least partially located in the guide slot 411 on a side of the cam 410 near the first leg 422. The sliding portion 421 provided at the second leg 423 may protrude toward a side of the second leg 423 near the cam 410, so that the sliding portion 421 provided at the second leg 423 may be at least partially positioned in the guide slot 411 of the side of the cam 410 near the second leg 423. In this embodiment, the cam 410 is at least partially positioned in the gap between the first leg 422 and the second leg 423, which may improve the stability of the drive connection between the cam 410 and the push rod 420.
Referring to fig. 7 and 8, the driving member 430 may be provided as a rack, and the driving member 430 is engaged with the cam 410 to drive. The driving member 430 is configured as a rack and is engaged with the cam 410 to improve the driving precision between the driving member 430 and the cam 410, thereby improving the flatness of the second support portion 310 and the first support portion 120 of the support plate 300 on the side supporting the screen 600.
In an alternative embodiment, the transmission 430 may include a rack segment and a link segment. The length of the rack segments may be equal to the length of the corresponding arcuate segments of the tooth structure on the cam 410. Specifically, during the process of switching the support plate 300 from the first position to the second position, the rack segment may drive the cam 410 to rotate, thereby driving the support plate 300 to move. With the support plate 300 in the second position, the cam 410 is located at an end of the rack section near the first housing 100. During continued approaching of the first and second housings 100, 200, the cam 410 moves from the rack segment to the link segment, and the drive between the drive 430 and the cam 410 fails. In this embodiment, the movement range of the support plate 300 in the direction approaching or separating from the screen 600 can be further achieved by adjusting the rotation angle of the cam 410 by adjusting the length of the rack section and/or the tooth structure on the cam 410 corresponding to the arc section.
There are many kinds of driving members 430, and in particular, the driving members 430 may be independent members or may be a linkage assembly formed by combining a plurality of members. For example: the transmission member 430 may also be a connecting rod, specifically, a first end of the connecting rod is hinged with the first housing 100, a second end of the connecting rod is hinged with the cam 410, and a hinge point of the connecting rod and the cam 410 is coaxial with a rotation axis of the cam 410, so that the cam 410 and the connecting rod form a crank-link mechanism. The transmission member 430 may also be a pull rope and a torsion spring, where the torsion spring is disposed on the cam 410, so that the cam 410 may drive the support plate 300 to move from the first position to the second position through the push rod 420 under the action of the torsion spring. The first end of the pull cord is connected to the first housing 100, the second end of the pull cord is connected to the cam 410, and the pull cord is at least partially windable around the cam 410. In the case that the first housing 100 is away from the second housing 200, the pull cord may drive the cam 410 to overcome the elastic force generated by the torsion spring and rotate, so that the support plate 300 may be switched from the second position to the first position. In the case that the first housing 100 approaches to the second housing 200, the torsion spring acts on the cam 410 to rotate, so that the cam 410 drives the support plate 300 to switch from the first position to the second position, and the pull rope is at least partially wound around the cam 410. For this reason, the embodiment of the present application is not limited to the specific kind of the transmission member 430.
Referring to fig. 11, the cam 410 may include an arc segment provided with a tooth structure. The driving member 430 may be a rack, and the driving member 430 is engaged with the circular arc segment. In this embodiment, the angle range of the driving member 430 driving the cam 410 to rotate can be limited by setting the circular arc segment corresponding to the central angle, so that the range of the cam 410 driving the support plate 300 to move through the push rod 420 can be limited. In addition, the cam 410 is provided with the arc section, and the tooth structure is arranged on the arc section, so that the structure of the cam 410 can be simplified, and the occupied space of the transmission assembly 400 can be reduced.

In this embodiment, the first thread segments and the second thread segments are threaded in opposite directions so that the lead screw 520 can synchronously drive the first housing 100 and the third housing 700 to move relative to the second housing 200. Also, in the case where the first housing 100 and the third housing 700 are connected to the same support plate 300 through the transmission assembly 400, it is possible to ensure that the displacement of each part of the support plate 300 with respect to the movement of the second housing 200 is equal. In addition, the screw rod 520 and the first screw sleeve 530 and the second screw sleeve 540 are driven to play a role in reducing speed, so that a reduction gearbox is not required to be arranged between the motor 510 and the screw rod 520, and the occupied space of the driving piece 500 is reduced.
