Description

Split-screen display device Technical Field

[0001] The present application relates to an extended display of a notebook computer, and more specifically to a split-screen display device. Background Art

[0002] Laptop computers are one of the most common computer terminals on the market. Generally, laptop computers consist of a single display screen and a flat computer body. There are also some portable split-screen display devices on the market that come with single, dual or triple screens and can be hung on the display screen of a laptop computer. The screens can be rotated and folded, and users can use the attached screens for viewing. The substrate of the split-screen display device is divided into two or three parts. The adjacent parts of the substrate are connected by a pull rod and can move relative to each other so that the clamping width of the substrate can be adjusted according to the size of the laptop screen. In the past, the structure connecting the adjacent parts of the substrate was a pull rod and a gear. The pull rod had a rack, and the gear and the rack formed an engagement. When the adjacent parts of the substrate moved relative to each other to adjust the width, due to the stepless adjustment of the gear rack engagement, there was no adjustment sound. Some users prefer to make a sound when adjusting the clamping width to enhance the sense of confirmation of the adjustment. Therefore, this previous structure failed to meet the diverse needs of users and needs to be improved. Application Contents

[0003] The purpose of this application is to overcome the above shortcomings of the prior art and provide a split-screen display device.

[0004] To this end, the present application provides the following technical solutions: a split-screen display device, comprising a clamping frame and at least one display screen, the display screen being arranged on the clamping frame, the clamping frame comprising a first bracket and a second bracket, the first bracket and the second bracket being connected by at least one pull rod; one end of the pull rod is fixed to the second bracket, and the other end is inserted into the first bracket, a spring pin assembly is provided in the first bracket, the pull rod is provided with a rack, the rack extends along the length direction of the pull rod, the spring pin assembly has a tooth head pointing vertically to the rack, the spring pin assembly presses the tooth head toward the rack, and the tooth head engages with the rack.

[0005] Compared with the prior art, the split-screen display device of the present application engages with the rack through the tooth head of the elastic pin assembly. When adjusting the clamping width between the first bracket and the second bracket, the first bracket and the second bracket are pulled apart relative to each other, the pull rod is pulled, and the rack moves linearly relative to the elastic pin assembly. During this process, the tooth head is continuously compressed and rebounded, and the rebounding tooth head makes a sound when hitting the rack. Therefore, the user can enhance the sense of confirmation of the adjustment through this sound when adjusting the clamping width, meeting the diverse needs of users; and when the tooth head is inserted into a certain tooth valley of the rack, the first bracket and the second bracket can be kept fixed at this width, and are not prone to loosening in the absence of external force.

[0006] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail as follows.

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0021] An embodiment of the present application is a split-screen display device, the specific structure of which is shown in Figures 1-6.

[0022] As shown in Figure 1, the split-screen display device includes a clamping frame 100 and two display screens 90. During use, the clamping frame 100 is clamped to the back of a laptop computer's display screen. The clamping frame 100 includes a first bracket 10 and a second bracket 20, with the two display screens 90 positioned on the left and right sides of the clamping frame 100, respectively. The first bracket 10 and the second bracket 20 can be moved apart to adjust the clamping width.

[0023] As shown in Figure 2 , the first bracket 10 and the second bracket 20 are connected by two tie rods 30 , one end of which is fixed to the second bracket 20 and the other end is inserted into the first bracket 10 . The tie rods 30 can be made of aluminum. In Figure 2 , there are two parallel tie rods 30 . However, in other embodiments, only a single center tie rod can be used to connect the first and second brackets.

[0024] 2 , there are latching slots 101 at the upper left, lower left, upper right, and lower right corners of the clamping frame 100. When in use, the upper two latching slots 10 are used to latch onto the left and right corners of the laptop screen, while the lower two latching slots 101 are used to latch onto the left and right sides of the laptop screen.

[0025] As shown in Figures 3 and 4 , a spring assembly 40 is installed within the first bracket 10. Specifically, the spring assembly 40 includes a push pin 41 and a compression spring 42. The spring assembly 40 has a tooth head 411 located at one end of the push pin 41. A guide rod 412 extends through the compression spring 42 at the other end of the push pin 41. The push pin 41 can be made of highly wear-resistant POM material, and the tooth head 411 is integrally formed with the push pin 41. A rack 50 is fixed to the pull rod 30, extending along the length of the pull rod 30. The tooth head 411 of the push pin 41 points perpendicularly toward the rack 50, and the spring assembly 40 presses the tooth head 411 toward the rack 50, causing the tooth head 411 to engage with the rack 50. In this embodiment, the compression spring 42 deforms under pressure, and the restoring force of the compression spring 42 pushes the push pin 411 toward the rack 50, creating a mutual pressure between the tooth head 411 and the rack 50. When the tooth head 411 is inserted into a tooth valley of the rack 50, the push of the compression spring 42 on the push pin 41 causes the tooth head 411 to be tightly pressed in the tooth valley, so that the first bracket 10 and the second bracket 20 can remain fixed in this position and are not prone to loosening in the absence of external force.

[0026] When the user is using the split-screen display device, if the user needs to adjust the clamping width between the first bracket 10 and the second bracket 20, the first bracket 10 and the second bracket 20 are pulled apart or retracted relative to each other, and the pull rod 30 moves linearly relative to the first bracket 10, and the rack 50 forms a linear motion relative to the spring pin assembly 40. During this process, the tooth head 411 is continuously compressed and rebounded. When the tooth head 411 rebounds, it is pushed by the restoring force of the compression spring 42, so that every time the tooth head 411 passes over a tooth, it will hit the rack 50 and make a sound. Therefore, when the user adjusts the clamping width, this sound can enhance the sense of confirmation of the adjustment, which can meet the diverse needs of users.

[0027] In other embodiments, the pin assembly can also be replaced with a ball screw. The top of the ball screw is a round ball, and a spring is provided inside to support the round ball. When the rack moves linearly, the round ball is continuously compressed and rebounded, which can also achieve the same effect.

[0028] In some embodiments, as shown in conjunction with Figures 3 and 4 , a vertical guide slot 13 is provided within the first bracket 10. The length of the guide slot 13 is perpendicular to the rack 50, and both the ejector pin 41 and the compression spring 42 are disposed within the guide slot 13. The ejector pin 41 moves linearly along the length of the guide slot 13, and the guide rod 412 passes through the bottom plate 131 of the guide slot 13. One end of the compression spring 42 abuts against the bottom plate 131 of the guide slot 13, and the other end abuts against the surface of the ejector pin 41. The restoring force of the compression spring 42 acts directly on the ejector pin 41. Furthermore, as shown in Figure 4 , a guide post 14 is provided within the guide slot 13, and the ejector pin 41 is provided with a guide hole 413. The guide post 14 passes through the guide hole 413. The function of the guide post 14 is to guide the up and down movement of the ejector pin 41. The guide post 14 has an internal threaded hole 141 , into which a screw 15 is screwed. The outer diameter of the head of the screw 15 is larger than the inner diameter of the guide hole 413 , so that the screw 15 can block the ejector pin 41 to prevent the ejector pin 41 from falling out of the guide groove 13 .

[0029] In some embodiments, as shown in Figures 3 and 4 , the pull rod 30 is provided with a limiting hole 31 extending along the length of the pull rod 30, and the first bracket 10 is provided with a limiting bar 12, which extends into the limiting hole 31. The limiting bar 12 is a long strip with semicircular ends, and its length is aligned with the length of the pull rod 30. The limiting hole 31 limits the horizontal travel of the limiting bar 12, thereby limiting the maximum travel of the first bracket 10 and the second bracket 20 apart from each other.

[0030] In some embodiments, as shown in FIG3 , a transverse guide slot 11 is provided in the first bracket 10, and the pull rod 30 is inserted into the transverse guide slot 11 and moves linearly along the length of the transverse guide slot 11. The transverse guide slot 11 serves to guide the horizontal movement of the pull rod 30, thereby limiting the horizontal relative movement of the first bracket 10 and the second bracket 20.

[0031] In some embodiments, when the first bracket 10 and the second bracket 20 are fitted together, the first bracket 10 and the second bracket 20 are fixedly fitted together by magnetic attraction to avoid a gap between the first bracket 10 and the second bracket 20. As shown in Figure 5, specifically, two first magnets 17 are provided on the inner wall of the side panel 16 of the first bracket 10 facing the second bracket 20, and two second magnets 22 are provided on the inner wall of the side panel 21 of the second bracket 20 facing the first bracket 10. The positions of the second magnets 22 correspond one-to-one to the positions of the first magnets 17. Therefore, when the first bracket 10 and the second bracket 20 are fitted together, the first bracket 10 and the second bracket 20 are fixedly fitted together by the magnetic attraction between the first magnets 17 and the second magnets 22. In other embodiments, the first magnet can be replaced with an iron block, or the second magnet can be replaced with an iron block to achieve the same magnetic attraction effect.

[0032] In some embodiments, as shown in Figure 6 , the pull rod 30 is provided with a strip-shaped receiving slot 32 extending along the length of the pull rod 30. The rack 50 is secured within the strip-shaped receiving slot 32 by a plurality of screws. The rack 50 is also made of highly wear-resistant POM. In other embodiments, each of the two pull rods may be equipped with a rack, with each rack corresponding to a set of spring pin assemblies.

[0033] In the example of FIG1 , the first bracket 10 is hingedly connected to a display screen 90, and the second bracket 20 is also hingedly connected to a display screen 90. In other embodiments, as shown in FIG7 , only the first bracket 10 can be hingedly connected to the display screen 90, while the second bracket 20 is not connected to the display screen. Alternatively, as shown in FIG8 , only the second bracket 20 can be hingedly connected to the display screen 90, while the first bracket 10 is not connected to the display screen.

[0034] In another embodiment, as shown in FIG9 , the clamping frame 100 further includes a third bracket 80. The third bracket 80 and the second bracket 20 are symmetrically disposed on the left and right sides of the first bracket 10. The connection structure between the third bracket 80 and the first bracket 10 is the same as the connection structure between the second bracket 20 and the first bracket 10. In FIG9 , the second bracket 20 is hingedly connected to a display screen 90, and the third bracket 80 is also hingedly connected to a display screen 90.

[0035] The above examples are merely used to further illustrate the technical content of this application to facilitate understanding by the reader, but do not limit the implementation of this application to these examples. Any technical extension or re-creation based on this application is protected by this application. The scope of protection of this application shall be based on the claims. Industrial Applicability
