[0001] The present invention relates to an electronic device with a liftable screen, and more particularly to an electronic device having a liftable screen. [Previous Technology]

[0002] Currently, the screen of most laptops is fixed relative to the laptop body. The screen height cannot be adjusted. A fixed-height screen is not ergonomic for taller users and may cause fatigue during prolonged use.

[0003] Therefore, how to improve electronic devices, such as notebook computers, through structural design improvements to overcome the above-mentioned defects has become an important issue that this technical field seeks to address. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide an electronic device with a liftable screen to address the shortcomings of the prior art, so that the screen can be raised or lowered.

[0005] To solve the above-mentioned technical problems, one of the technical solutions adopted by the present invention is to provide an electronic device with a liftable screen, which includes a base, a screen, and a lifting mechanism. The screen is electrically coupled to the base, and a fixed seat is provided on the back of the screen. The lifting mechanism enables the screen to be in a lowered position and an raised position relative to the base. The lifting mechanism includes a brake rod, an elastic member, and a pair of connecting rods. The bottom end of the brake rod is fixed to the base, and the brake rod passes through the fixed seat. One end of the elastic member abuts against the base and provides an elastic force to move the screen away from the base. The pair of connecting rods connect the base and the screen.

[0006] One of the beneficial effects of the present invention is that the electronic device with a liftable screen provided by the present invention can be disposed between the screen and the base by means of a lifting mechanism. The brake rod of the lifting mechanism is fixed to the base and passes through the fixed seat. One end of the elastic member of the lifting mechanism abuts against the base and provides elastic force to move the screen away from the base. The technical solution of a pair of connecting rods disposed between the base and the screen allows the screen of the electronic device to rise or fall, which is more ergonomic.

[0007] To further understand the features and technical content of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings provided are for reference and illustration only and are not intended to limit the present invention.

Implementation Method

[0008] Referring to Figures 1 to 3, the present invention provides an electronic device 100 with a liftable screen, hereinafter referred to as electronic device 100. Electronic device 100 includes a base 20, a screen 30, and a lifting mechanism 40. The lifting mechanism 40 enables the screen 30 to be in a lowered position (as shown in Figures 1 and 2) or an raised position relative to the base 20 (as shown in Figures 4 and 5).

[0009] In this embodiment, the electronic device 100 is exemplified by a notebook computer. The base 20 in this embodiment refers to a rotatable portion disposed on the device body 10. In this embodiment, the device body 10 includes a keyboard and related operating electronic components. However, the invention is not limited thereto; the electronic device may be a television set, a tablet computer, etc.; the base may refer to the portion of the electronic device placed on a desktop, such as the stand of a television set.

[0010] The screen 30 is electrically coupled to the base 20. The above-mentioned "electrical coupling" may include a wired method, such as a flexible flat cable (not shown), or a wireless connection method. The screen 30 has a front side 301 and a back side 302. In this embodiment, the front side 301 refers to the part that displays information, and the back side 302 is opposite to the front side 301.

[0011] As shown in Figures 2 and 3, a fixing seat 32 is provided on the back surface 302 of the screen 30. The fixing seat 32 can be fixed to the back surface 302 of the screen 30 by means of screws. In this embodiment, the fixing seat 32 is located in the middle of the back surface 302 of the screen 30. Specifically, the fixing seat 32 includes a fixing plate 321 and a connecting sleeve 322. The fixing plate 321 is fixed to the back surface 302 of the screen 30, and the fixing plate 321 can be locked to the screen 30 by screws. The connecting sleeve 322 is connected to the fixing plate 321. In this embodiment, the connecting sleeve 322 protrudes outward from the fixing plate 321 and is a hollow semi-cylindrical shape.

[0012] The lifting mechanism 40 includes a brake lever 41, an elastic element 43, and a pair of connecting rods 45. In this embodiment, the brake lever 41 is a cylindrical rod. The bottom end of the brake lever 41 is fixed to the base 20 and passes through the fixed seat 32. The bottom end of the elastic element 43 abuts against the base 20 and provides an elastic force to move the screen 30 away from the base 20. For example, in this embodiment, the elastic element 43 is a compression spring and is sleeved on the brake lever 41, and the top end of the elastic element 43 abuts against the fixed seat 32. The pair of connecting rods 45 connect the base 20 and the screen 30 to smoothly raise or lower the screen 30. The brake lever 41 movably passes through the connecting sleeve 322 of the fixed seat 32. In addition, the top end of the elastic element 43 abuts against the connecting sleeve 322 of the fixed seat 32.

[0013] A pair of connecting rods 45 of the lifting mechanism 40 are respectively disposed on both sides of the brake lever 41. The pair of connecting rods 45 can limit the rising height of the screen 30. Each connecting rod 45 has one end pivotally connected to the fixed base 32 and the other end pivotally connected to the base 20. Specifically, each connecting rod 45 has a first rod body 451 and a second rod body 452. The first rod body 451 has a first upper end 4511 pivotally connected to the fixed base 32 and a first lower end 4512 pivotally connected to the second rod body 452. The second rod body 452 has a second upper end 4521 pivotally connected to the first rod body 451 and a second lower end 4522 pivotally connected to the base 20.

[0014] In this embodiment, each link 45 may also be provided with a damping hinge 453, for example, located at the pivot joint between the first link 451 and the second link 452. For example, the damping hinge may be a noise-absorbing hinge that utilizes the directional flow of high-density oil in a closed space to achieve an ideal buffering effect. Alternatively, the damping hinge may use friction to provide motion resistance; for example, multiple friction pads may be provided at the pivot joint between the first link 451 and the second link 452. This allows the screen 30 to rise or fall slowly, reducing impact force.

[0015] This embodiment also includes a pair of guide rods 42, which are disposed on the base 20 and located on the back of the screen 30, for guiding the movement of the screen 30 relative to the base 20. The bottom end of the guide rod 42 is fixed to the base 20, and the guide rod 42 can slide relative to the screen 30, so that the screen 30 can rise or fall along the guide rod 42. However, the present invention is not limited thereto; for example, the number of guide rods may be at least one.

[0016] More specifically, the back surface 302 of the screen 30 is provided with a pair of guide rails 31, and the guide rod 42 is slidably disposed in the guide rails 31. In this embodiment, the guide rod 42 may be a cylindrical rod, and the guide rail 31 has a groove 310 corresponding to the guide rod 42 to accommodate the guide rod 42.

[0017] As shown in Figures 1 and 2, in this embodiment, the back surface 302 of the screen 30 is further provided with a back cover 36 and a pair of guide covers 38. The guide covers 38 are located on both sides of the back cover 36. The guide covers 38 cover the guide rail 31.

[0018] It is worth noting that a guide limiting mechanism is provided between the guide cover 38 and the guide rod 42 in this embodiment. Referring to Figures 2 and 7, the guide rod 42 has a limiting groove 420 facing the guide cover 38, and the guide cover 38 has a guide protrusion 381 facing the guide rod 42. The guide protrusion 381 is slidably disposed within the limiting groove 420. In addition, the guide rod 42 may also have an inner limiting groove 422 facing the screen 30, and the guide rail 31 of the screen 30 also has an inner protrusion 311, which is slidably disposed within the inner limiting groove 422. In this way, the above-mentioned guide limiting mechanism can reduce the friction during the rising or falling process of the screen 30, thereby guiding the rising or falling of the screen 30 more smoothly.

[0019] This embodiment also provides a positioning mechanism to position the screen 30 in a lowered position, that is, abutting against the base 20. As shown in Figures 3 and 6, for example, this embodiment may provide a magnetic positioning mechanism, which includes at least one first magnetic member 323 and one second magnetic member 413. The magnetic member can be a strong magnet. More specifically, the screen 30 is provided with two first magnetic members 323, which are fixedly located on the fixing base 32 and on both sides of the connecting sleeve 322. In other words, the two first magnetic members 323 are located on both sides of the brake lever 41. In addition, the second magnetic member 413 is located in a fixed position relative to the base 20. Specifically, the second magnetic member 413 may be embedded in the brake lever 41.

[0020] As shown in Figure 3, when the screen 30 is in the lowered position, the first magnetic member 323 and the second magnetic member 413 are at the same horizontal position and close to each other. The first magnetic member 323 and the second magnetic member 413 of the fixing base 32 can attract each other. In this way, the first magnetic member 323 can be attracted to the second magnetic member 413 to position the screen 30 in the lowered position. The magnetic attraction force of the two magnetic members is slightly greater than the force of the elastic member 43 pushing the screen 30 upward, thereby overcoming the upward pushing force of the elastic member 43 and fixing the screen 30 in the lowered position relative to the base 20.

[0021] As shown in Figure 6, when a user wishes to raise the screen 30, applying an upward force greater than the aforementioned magnetic attraction force, the screen 30 rises from the lowered position (as shown in Figures 2 and 3) away from the base 20. Then, the lifting mechanism 40 guides the screen 30 to the raised position (as shown in Figures 4 and 5). The elastic force of the elastic member 43 allows the screen 30 to rise automatically. During the rising process, a pair of connecting rods 45 disposed between the base 20 and the screen 30 can smoothly raise the screen 30 and limit the height of the rise.

[0022] When the user wants to lower the screen 30, they apply an elastic force to overcome the elastic member 43, which will lower the screen 30 until it contacts the base 20. As shown in Figure 3, at the same time, the first magnetic member 323 can be attracted to the second magnetic member 413 to position the screen 30 in the lowered position.

[0023] The position of the magnetic attractor of the present invention is not limited to the above-described embodiments. For example, the first magnetic attractor can be disposed on the bottom surface of the screen 30, and the number can be at least one; the second magnetic attractor can be disposed on the top surface of the fixing base 32, and the number can be at least one, with the two magnetic attractors positioned opposite each other and attracting each other. Furthermore, the present invention is not limited to a magnetic positioning mechanism for fixing the screen. For example, the present invention can provide a snap-fit ​​positioning mechanism between the screen 30 and the fixing base 32, and the snap-fit ​​positioning mechanism can be disposed on the fixing base 32 and snap-fit ​​the screen 30 in a lowered position. When the snap-fit ​​is released, the screen 30 can be raised upward by the pushing force of the elastic member 43.

[0024] [Beneficial Effects of the Embodiments]
