Description

Technical Field

[0001] This utility model belongs to the field of electronic product accessories, specifically relating to a multi-slider combined support type telescopic device. Background Technology

[0002] As we all know, various electronic devices (such as mobile phones, tablets, etc.) are constantly being updated and upgraded in order to display richer information to users, improve the efficiency of human-computer interaction, and enhance the user experience. As a result, the screen size is getting bigger and bigger. Correspondingly, electronic devices with large screens will bring problems of inconvenience in carrying and storing them.

[0003] Therefore, to solve the above problems, flexible rollable screen technology has emerged. It mainly adopts a folding structure or rolls the screen onto a roller. By releasing or retracting the rollable screen, display segments of different sizes can be obtained. At the same time, in order to assist the rollable screen's unfolding and retraction, existing electronic devices usually use telescopic brackets to guide the telescopic movement during the unfolding and retraction of the screen. For example, Chinese patent with publication number CN222545874U discloses a telescopic slide rail including a first strip track, a second strip track, and at least one intermediate strip track. The first strip track, at least one intermediate strip track, and the second strip track are sequentially slidably connected along the telescopic slide rail's extension and retraction direction, which is parallel to the extension and retraction direction of the telescopic bracket. The first strip track is connected to a first housing, and the second strip track is connected to a second housing.

[0004] However, in actual use, the telescopic slide rails used in the existing technology are not only complex in structure and cumbersome to disassemble and assemble, but also occupy a lot of space (making the electronic device appear thicker overall). Moreover, due to the limitations of the existing telescopic slide rail structure, they cannot provide synchronous support for the screen during telescopic movement, thus limiting the width of the screen. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved multi-slider combined support type telescopic device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A multi-slider combined support telescopic device includes two sets of telescopic units arranged near the two edges of the rollable screen in the width direction. Each set of telescopic units includes multiple support sliders that are slidably connected along the rollable screen's unfolding direction. The multiple support sliders are sequentially spliced ​​from the outside to the inside along the width direction of the rollable screen, and each support slider forms a support surface from the top. As the rollable screen unfolds, the multiple support sliders slide relative to each other and extend and retract synchronously. The multiple support surfaces remain flush and form a support plane that can support the back of the rollable screen.

[0008] Preferably, during retraction, the two ends of the multiple support sliders are aligned correspondingly in the extension / retraction direction. Here, in the minimum unfolded state of the entire machine, the support surfaces formed by each support slider can be distributed side by side from the outside to the inside to cooperate in supporting the rollable screen.

[0009] According to a specific embodiment and preferred aspect of this utility model, each support slider includes a slider body forming a support surface, a first limiting body and a second limiting body disposed on the slider body, wherein each slider body is slidably connected to an adjacent slider body and reciprocates between the first limiting body and the second limiting body. This achieves precise control over the maximum unfolding stroke of the entire machine.

[0010] Preferably, the slider body includes a first segment, a second segment disposed on the top of the first segment and forming a supporting surface, and a third segment disposed on the outside of the first segment. The inner side of the first segment has a groove extending along the unfolding direction of the rollable screen. A first limiting body and a second limiting body are respectively disposed within the groove. The third segment is slidably connected within the groove of an adjacent first segment. The groove extends through both ends of the corresponding first segment, facilitating the insertion and assembly of adjacent supporting sliders.

[0011] Specifically, in the orthographic projection along the extension direction, the grooves of multiple support sliders are aligned internally and externally; and / or, the cross-section of each groove is T-shaped. This internally and externally aligned arrangement of the grooves of multiple support sliders improves the stability of internal and external sliding.

[0012] Preferably, the second segment gradually narrows upwards from the top of the first segment, and the second segment forms a supporting surface from the top; and / or, the outer wall of the second segment is flush with the outer wall of the first segment. This provides stronger edge support for the rollable screen, reduces the probability of deformation, and extends its service life.

[0013] Preferably, the first limiting body is a limiting post detachably connected to one end of the first segment; the other end of the first segment is recessed from the inner wall outward to form a groove communicating with the slide groove, and the second limiting body is a limiting block embedded in the groove, with adjacent first segments maintaining a blocking effect on the limiting block during sliding. Here, the extension and retraction stroke of each support slider is precisely controlled based on the first and second limiting bodies, and the positioning of the second limiting part is achieved by utilizing the cooperation between the support sliders, making disassembly and assembly simple and convenient.

[0014] Specifically, the limiting block includes a first block and a second block that intersect perpendicularly. The first block is inserted into a slide groove and extends along the slide groove, while the second block is inserted into a recess. Based on the cooperation of the first and second blocks within the slide groove and the recess, the limiting block can be quickly aligned and installed.

[0015] Preferably, a connecting block is provided on the outer side of the first segment, and the third segment is disposed on the connecting block and fits against the inner wall of the adjacent slide groove. The first segment is made of metal, and the third segment is made of plastic. Therefore, while increasing the overall structural strength, the frictional force between the third segment and the first segment is reduced.

[0016] In addition, each telescopic unit also includes a connecting slider that moves synchronously with the movable end of the rollable screen, and the innermost support slider is slidably connected to the connecting slider along the telescopic direction.

[0017] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0018] Existing telescopic slide rails are not only complex in structure and cumbersome to assemble and disassemble, but also occupy a large amount of space (making the overall electronic device appear thicker). Moreover, due to the limitations of existing telescopic slide rail structures, they cannot synchronously support the screen during telescopic movement, thus limiting the screen's width. This application, however, redesigns the structure of a multi-slider combined support telescopic device, cleverly solving the shortcomings and defects of existing technologies. With this telescopic device, as the rollable screen expands and contracts, multiple support sliders on both sides slide relative to each other and telescopically extend and contract synchronously. The support surfaces formed by each support slider are flush and maintain support for the back of the rollable screen. Simultaneously, based on the sliding support formed by the support sliders on both sides, the edges of the rollable screen can extend to both sides onto the support planes formed by the support sliders, thereby maximizing the width of the rollable screen. Therefore, compared with the prior art, this utility model has two advantages. First, it is based on the sequential splicing and sliding connection of multiple support sliders inside and outside, which makes the structure simple and compact, which is conducive to the thinning design of the overall structure and effectively improves the user experience. Second, based on the support plane formed by the cooperation of the support sliders on both sides, the screen can move and slide synchronously during the screen unfolding and retraction, and the edge of the rollable screen can be extended to both sides, which is conducive to maximizing the width of the rollable screen and improving the display effect.

[0032] like Figures 1 to 6 As shown, the multi-slider combination support telescopic device involved in this embodiment includes two sets of telescopic units S arranged near the two edges of the rollable screen in the width direction. Each set of telescopic units S includes multiple support sliders 1 and connecting sliders 2 that are slidably connected along the rollable screen's unfolding direction.

[0033] Specifically, multiple support sliders 1 are sequentially assembled from the outside to the inside along the width direction of the rollable screen, and each support slider 1 forms a support surface m from the top. As the rollable screen expands and contracts, the multiple support sliders 1 slide relative to each other and extend and retract synchronously, with the multiple support surfaces m remaining flush and forming a support plane that can support the back of the rollable screen. During contraction, the two ends of the multiple support sliders 1 are aligned correspondingly in the extension and retraction direction. Here, in the minimum unfolded state of the entire machine, the support surfaces formed by each support body can be distributed side by side from the outside to the inside to cooperate in supporting the rollable screen. In this embodiment, there are 3 support sliders 1 and 1 connecting slider 2.

[0034] For ease of implementation, the two outermost and innermost support sliders 1 are fixed relative to each other in the width direction of the rollable screen. Multiple support sliders 1 are sequentially spliced ​​from the outside to the inside, forming mutual limiting in the width direction of the rollable screen. The connecting slider 2 moves synchronously with the movable end of the rollable screen, and the innermost support slider 1 slides along the unfolding direction of the rollable screen and connects to the connecting slider 2. This increases the compactness of the structure between the support sliders, and the mutual abutment and limiting between the support sliders effectively enhances the stability of the overall structure and improves the unfolding quality of the rollable screen.

[0035] In some specific embodiments, each support slider 1 includes a slider body 10 forming a support section m, a first limiting body 11 and a second limiting body 12 disposed on the slider body 10, wherein each slider body 10 is slidably connected to an adjacent slider body 10 and reciprocates between the first limiting body 11 and the second limiting body 12. This achieves precise control over the maximum unfolding stroke of the entire machine.

[0036] In this example, the slider body 10 includes a first segment 101, a second segment 102 disposed on the top of the first segment 101 and forming a supporting surface m, and a third segment 103 disposed on the outside of the first segment 101 (the third segment may not be disposed on the outermost slider body). The inner side of the first segment 101 forms a groove c0 extending along the retracting direction of the roll-up screen. A first limiting body 11 and a second limiting body 12 are respectively disposed within the groove c0. The third segment 103 is slidably connected within the groove of an adjacent first segment 101. The groove passes through both ends of the corresponding first segment, facilitating the insertion and assembly of adjacent supporting sliders.

[0037] Specifically, in the orthographic projection along the extension direction, the grooves c0 of the multiple support sliders 1 are aligned internally and externally; the cross-section of each groove c0 is T-shaped. This internally and externally aligned arrangement of the grooves of the multiple support sliders improves the stability of internal and external sliding.

[0038] Meanwhile, the second segment 102 gradually narrows upwards from the top of the first segment 101, and the second segment 102 forms a supporting surface m from the top; the outer wall of the second segment 102 is flush with the outer wall of the first segment 101. This provides stronger support for the edges of the rollable screen, reduces the probability of deformation, and extends its service life.

[0039] To further facilitate implementation, a connecting block k is provided on the outer side of the first segment 101, and the third segment 103 is disposed on the connecting block k and fits against the inner wall of the adjacent slide groove c0. A U-shaped groove is formed on the connecting block k, and the third segment 103 is inserted into the U-shaped groove and protrudes from the side of the U-shaped groove to fit against the inner wall of the adjacent slide groove c0. The first segment is made of metal, and the third segment is made of plastic. Therefore, while increasing the overall structural strength, the frictional force between the third segment and the first segment is reduced.

[0040] In this example, the first limiting body 11 is a limiting post (e.g., a pin) detachably connected to one end of the first split body 101; the other end of the first split body is recessed outward from the inner wall to form a groove c1 communicating with the slide groove c0; the second limiting body 12 is a limiting block embedded in the groove c1, and the adjacent first split body 101 maintains a blocking effect on the limiting block during sliding. Here, the extension and retraction stroke of each support slider is precisely controlled based on the first and second limiting bodies, and the positioning of the second limiting part is achieved by utilizing the cooperation between the support sliders, making disassembly and assembly simple and convenient.

[0041] Specifically, the limiting block includes a first block 121 and a second block 122 that intersect perpendicularly. The first block 121 is inserted into and extends along the slide groove c0, and the second block 122 is inserted into the recess c1. Based on the cooperation of the first block 121 and the second block 122 within the slide groove c0 and the recess c1, the limiting block can be quickly aligned and installed.

[0042] In addition, to further facilitate processing and assembly, a groove extending along the unfolding direction of the roll-up screen is formed on the inner side of the innermost support slider 1. Limiting bodies are formed at both ends of the groove. The connecting slider 2 is slidably connected in the groove and moves between the two limiting bodies (similar to the sliding connection structure between adjacent support sliders).

[0043] In summary, with this telescopic device, as the rollable screen expands and contracts, the multiple support sliders on both sides slide relative to each other and extend and contract synchronously. The support surfaces formed by each support slider are flush and maintain support for the back of the rollable screen. Simultaneously, based on the sliding support formed by the support sliders on both sides, the edges of the rollable screen can extend to the support planes formed by the support sliders, thereby maximizing the width of the rollable screen. Therefore, compared with existing technologies, this invention, firstly, is based on multiple support sliders sequentially spliced ​​inside and out and slidingly connected, resulting in a simple and compact structure that facilitates thinning of the overall structure and effectively improves the user experience; secondly, based on the support plane formed by the support sliders on both sides, it achieves synchronized sliding support during screen expansion and contraction, allowing the edges of the rollable screen to extend to both sides, thus maximizing the width of the rollable screen and improving the display effect; thirdly, in the smallest unfolded state, the support surfaces formed by each support body can be distributed side-by-side from the outside to collaboratively support the rollable screen; Fourthly, the alignment of the inner and outer grooves of multiple supporting sliders improves the stability of inner and outer sliding. Fifthly, the precise control of the extension and retraction stroke of each supporting slider by the first and second limiting bodies, along with the positioning of the second limiting body through the cooperation between the supporting sliders, makes disassembly and assembly simple and convenient. Sixthly, the cooperation between the first and second blocks in the grooves and slots enables the quick alignment and installation of the limiting blocks. Seventhly, the first part is made of metal and the third part is made of plastic, thus increasing the overall structural strength while reducing the frictional force between the third part and the first part.
