Description

Technical Field

[0001] The present invention relates to the field of portable electronic terminals, and in particular to a support mechanism for a scroll screen terminal used therein. The portable electronic terminal may be a mobile phone, a pad, a notebook computer, or the like. Background Art

[0002] Roll-up screen terminals use a flexible screen that can be rolled up. The folded portion is rolled around a shaft and pulled outward when a larger screen is needed. Therefore, how to support the extended width is one of the key parts to ensure the user experience.

[0003] At present, there is no mature mass-produced machine on the market. One of the main reasons is that the problem of supporting structure has not been solved. Summary of the Invention

[0004] The purpose of the present invention is to provide a support mechanism suitable for scroll screen terminals, which can solve the difficulties encountered in the background technology with a relatively simple structure, so as to facilitate product design and industrial application according to customer requirements. To this end, the present invention adopts the following technical solutions:

[0005] A multi-section magnetic support mechanism, comprising a first side body and a second side body, wherein the second side body is slidably connected to the first side body, and wherein the support mechanism is further provided with a plurality of extension supports and a plurality of sliding supports; and the first side body and the second side body are respectively provided with a first side support body and a second side support body;

[0006] The plurality of sliding supports are arranged one by one along the sliding direction of the second side body and are located between the first side body and the second side body, and the plurality of sliding supports are slidably connected to the first side body;

[0007] The plurality of extended support bodies are arranged one by one between two adjacent sliding support bodies, between the sliding support body closest to the second side and the second side support body, and between the sliding support body closest to the first side and the first side support body;

[0008] The extended support body is a support body that can be raised and lowered. When the extended support body is raised, it forms a flexible screen support surface together with the first side support body, the second side support body and the multiple sliding support bodies; when the second side body slides toward the second side to the maximum extended state, the multiple extended support bodies are all raised, and form a flexible screen support surface together with the first side support body, the second side support body and the multiple sliding support bodies;

[0009] The cam is adapted to move the sliding support body to the second side so that the cam can be pulled and pushed by the second side support body, and the sliding support body to the second side is adapted to move the sliding support body to the second side so that the cam can be pulled and pushed by the second side support body.

[0010] A control mechanism for controlling the lowering of the extension support body is also provided between the extension support body closest to the first side and the first side support body, and a control mechanism for controlling the lowering of the extension support body is provided between the other extension support bodies and the sliding support body located on the first side thereof, so that all of the multiple extension support bodies can be lowered before the second side body slides from a fully extended state to a retracted state.

[0011] On the basis of adopting the above technical solutions, the present invention may also adopt the following further technical solutions at the same time, or use these further technical solutions in combination:

[0012] When all the extended support bodies are lowered, the first side support body, the multiple sliding support bodies and the second side support body are sequentially spliced ​​into a flexible screen support surface of the scroll screen terminal in the folded state.

[0013] The extended support body closest to the second side is rotatably connected to the second side support body and connected to a torsion spring, and the other extended support bodies are rotatably connected to the sliding support body located on its second side and connected to a torsion spring; the extended support body is also provided with a gear structure, and through the torsion spring and the gear structure, when the second side body slides toward the second side, the extended support bodies from the extended support body closest to the second side to the extended support body closest to the first side are rotated and lifted upward one by one.

[0014] The sliding support body located on the first side of the extended support body acts as a blocking structure for the extended support body located on its second side and is squeezed by the torsion spring; the first side body or the first side support body acts as a blocking structure for the extended support body closest to the first side and is squeezed by the torsion spring.

[0015] The expansion support body and the sliding support body are both in the shape of long strips.

[0016] Before the second side body slides from the fully extended state to the retracted state, the plurality of expansion supports are rotated and lowered one by one in the order from the expansion support closest to the first side to the expansion support closest to the second side.

[0017] The force values ​​of the torsion springs connected to different extension support bodies are different, so that before the second side body slides from the fully extended state to the retracted state, the multiple extension support bodies are rotated and lowered one by one in the order from the extension support body closest to the first side to the extension support body closest to the second side.

[0018] Another object of the present invention is to provide a scroll screen terminal using the above-mentioned support mechanism. To this end, the present invention adopts the following technical solutions:

[0019] A scroll screen terminal includes a rollable flexible screen, characterized in that the scroll screen terminal is also provided with any of the above-mentioned multi-section magnetic support mechanisms, the flexible scroll is installed in the first side body, the flexible screen and the first side support body are slidably matched, and the non-scroll end of the flexible screen is fixedly connected to the second side support body.

[0020] Due to the adoption of the technical solution of the present invention, the present invention has a simple structure, can realize sequential lifting and lowering, and is convenient for flexibly setting parameters according to the requirements of different customers, which can solve the problem of industrial mass production of scroll screen terminals.

[0032] Referring to the accompanying drawings, a multi-section magnetic support mechanism includes a first side body 101 and a second side body 102, wherein the second side body 102 and the first side body 101 are slidably connected. Reference numeral 1011 represents a track on the first side body, and a sliding connector on the second side body 102 cooperates with the track 1011. The support mechanism is further provided with a plurality of sliding supports 103 and a plurality of extension supports 104; the first side body 101 and the second side body 102 are respectively provided with a first side support 1010 and a second side support 1020.

[0033] The first side body 101 and the second side body 102 can be two relatively slidable shells of the scroll screen terminal, or components fixedly connected to the shells. Generally speaking, the scroll of the flexible screen is set within the shell on the side of the first side body 101. The flexible screen 200 extends from this side body and is fixedly connected to the second side support body 1020 on the second side body 102, and slides with the first side support body 1010 on the first side body 101. The expansion support body 104 and the sliding support body 103 are both in the shape of long strips.

[0034] The plurality of sliding supports 103 are arranged one by one along the sliding direction of the second side body 102 and are located between the first side body 101 and the second side body 102. The plurality of sliding supports are slidably connected to the first side body, and the sliding connectors of the sliding supports 103 engage with the tracks 1012 on the first side body. In this embodiment, two sliding supports 103 are provided, numbered 1031 and 1032, respectively, from the first side to the second side.

[0035] The multiple extended support bodies 104 are arranged one by one at intervals between two adjacent sliding support bodies 103, between the sliding support body 1032 closest to the second side and the second side support body 1020, and between the sliding support body 1031 closest to the first side and the first side support body 101; in this embodiment, a total of three extended support bodies 104 are arranged, from the first side to the second side, respectively numbered 1041, 1042, and 1043.

[0036] The extension support 104 is a support that can be raised and lowered. By raising and lowering it, the support surface can adapt to the area change caused by the extension and retraction of the screen. After the extension support 104 is raised, it forms a flexible screen support surface together with the first side support 1010, the second side support 1020 and the plurality of sliding supports 103; when the second side body 102 slides toward the second side (rightward in the figure) to the maximum extension state, the plurality of extension supports are all raised, and together with the first side support 101, the second side support 1020 and the plurality of sliding supports 103, form a flexible screen support surface in the fully extended state ( Figure 4-2 ); When the extended support body 104 is completely lowered, the first side support body 101, the plurality of sliding support bodies 103 and the second side support body 1020 are sequentially spliced ​​to form a flexible screen support surface of the retracted state scroll screen terminal ( Figure 2-2 、 6-2 ).

[0037] A connection structure is set between the extension support body 1043 closest to the second side and the second side support body 1020 so that it can be pushed and pulled by the second side support body 1020. Connection structures are set between the other extension support bodies 1042 and 1041 and the sliding support bodies 1031 and 1032 located on the second side thereof, respectively, so that they can be pushed and pulled by the sliding support bodies 1031 and 1032 located on the second side thereof; a magnetic attraction structure is set between the extension support body 1041 closest to the first side and the first side support body 101, and the other extension support bodies 1042 and 1041 are respectively connected to the sliding support bodies 1031 and 1032 located on the second side thereof. A magnetic structure is provided between the extended support body 1043 and the sliding support bodies 1031 and 1032 located on the first side thereof, and after the extended support body 104 is lifted, the magnetic structure is connected to the sliding support body 103 as a whole, thereby pulling the connected structure located on the first side thereof to slide toward the second side; when the second side main body slides toward the second side from the retracted state, the extended support body 1043 located closest to the second side to the extended support body 1041 located closest to the first side are lifted one by one and pull the sliding support body located on the first side thereof to continue sliding toward the second side.

[0038] The magnet 105 in the magnetic attraction structure is preferably a magnetic rod, positioned adjacent to the extension support 104 and the sliding support 103, as well as adjacent to the extension support 104 and the first support 101 (which can be on the second side of the first side support 1010 on the first side body 101). Another preferred solution is to position magnets (magnetic rods 105) on the sliding support 103 and the first support 101, while placing a material attracted by the magnets, such as a thin steel bar, on the extension support 104. Reference numeral 1050 denotes a mounting slot for the magnetic rod.

[0039] A control mechanism for controlling the lowering of the extension support body is also provided between the extension support body 1041 closest to the first side and the first side support body 1010, and a control mechanism for controlling the lowering of the extension support body is provided between the other extension support bodies 104 and the sliding support body 103 located on the first side thereof, so that all the multiple extension support bodies can be lowered before the second side body slides from the fully extended state to the folded state.

[0040] The extension support 1043 closest to the second side is rotatably connected to the second side support 1020 and is connected to a torsion spring 106. The other extension supports 1041 and 1042 are rotatably connected to the sliding supports 1031 and 1032 located on their second sides and are connected to torsion springs. Reference numeral 1044 designates an axis for the rotatable connection. The extension support 104 is further provided with a shifting structure 1045. By means of the torsion spring 106 and the shifting structure, when the second side body 102 slides toward the second side, the extension supports 1043 closest to the second side to the extension support 1041 closest to the first side are rotated and lifted one by one. The torsion spring 106 can be sleeved on the axis 1044, with one end inserted into the extension support 104 and the other end connected to the second side support 1020 or the sliding support 103.

[0041] For the shifting structure 1045, the preferred solution is that the sliding support body 103 located on the first side of the extended support body acts as a shifting structure for the extended support body 104 located on its second side, plays the role of a shifting structure, and is squeezed by the torsion spring 106; the first side support body 1010 plays the role of a shifting structure for the extended support body 1041 closest to the first side and is squeezed by the torsion spring 106.

[0042] The one-by-one rise is related to the sliding distance of the second side body 102, that is, in the folded state, the extended support body 104 is all lowered, and the first side support body 101, the multiple sliding support bodies 103 and the second side support body 1020 are sequentially spliced ​​into the flexible screen support surface of the scroll screen terminal in the folded state, and there are basically butt joints or only very small gaps between adjacent ones. When the second side body 102 is pulled open (to the right as shown in the figure), driving the flexible screen to be pulled open to expand the display area, the gap between the second side body 102 and the sliding support body 1031 adjacent to it gradually increases. At the same time, the extended support body 1043 closest to the second side pulled by the second side body 102 is also pressed upward against the sliding support body 1032 located on its first side under the action of the torsion spring and gradually lifted upward. When it is finally lifted up, it is located between the sliding support body 1032 and the second side body 102 arranged on its first side, and together with the first side support body 1010, the multiple sliding support bodies 103 and the second side support body 1020, it forms the flexible screen support surface of the scroll screen terminal in the folded state after the display area is expanded. At the same time, in this position, the magnetic structure connects the extended support body 1043 closest to the second side with the sliding support body 1032 arranged on its first side. When the second side body 102 continues to slide toward the second side, the sliding support body 1032 is also driven by the extended support body 1043 to slide together, and the extended support body 1042 located on the first side of the sliding support body 1032 is also driven, and the above working process is repeated. The extended support body 1043 located closest to the second side to the extended support body 1041 closest to the first side are rotated upward and lifted one by one.

[0043] The connection structure may also adopt a matching structure of a guide groove and a guide pin, rather than a rotational connection in the form of an axial connection.

[0044] The control mechanism can be a cam structure, comprising a first portion 1071 located on the side of the first side support body 101 and each sliding support body 103 close to the second side, and a second portion 1072 located on the side of the extension support body 104 close to the first side. When the extension support body is pushed toward the first side, the cam is controlled to force the extension support body 104 to rotate downward. The first portion 1071 can also serve as the stop structure 1045.

[0045] The order in which the multiple extended supports 104 are lowered can be all at the same time, but preferably they are lowered sequentially, which makes the operation easier. Furthermore, preferably, they are lowered one by one in the order from the extended support 1041 located closest to the first side to the extended support 1043 located closest to the second side, and after being lowered, the sliding support located on the second side continues to slide toward the first side. This sequential descent can be achieved by setting the force values ​​of the torsion springs 106 or the force values ​​of the magnetic bars 105 connected to different extended supports so that the reaction force that each support needs to overcome during the push-pull process is different, and the reaction force generated by the extended support that needs to be lowered first is smaller.
