Electronic device and multi-computer switching equipment

Abstract

An electronic device comprises a base, a screen module and a screen locking module. The screen module has a positioning portion. The base is pivoted to the screen module and is configured to move along with the sliding rail in the pull-out direction. The screen locking module is arranged on the base and comprises a first positioning block. The first positioning block is movably connected with the base and is provided with a clamping part used for being clamped with the positioning part. The moving direction of the first positioning block is perpendicular to the pulling-out direction. When the electronic device is located at the storage position, the screen module is closed towards the base, and the clamping part is clamped with the positioning part. When the base is moved to the use position from the storage position in the pull-out direction, the first positioning block is pushed by the pushing part of the sliding rail and moves in the direction close to the base, so that the clamping part is not clamped with the positioning part. By means of the design, the situation that the screen module is opened due to the fact that the difference between the height of a user and the installation height of the electronic device in the cabinet is too large when the user pulls out and pushes in the electronic device can be avoided, and the safety and stability of the pulling-out and pushing-in process are improved.

Description

Technical Field

[0001] The present disclosure relates to an electronic device and a multi-computer switching device having the electronic device. Background Art

[0002] For the need of automated monitoring, a keyboard-video-mouse switch with a liquid crystal display (LCD keyboard-video-mouse switch, LCD KVM switch) has been widely used in the industry. Its appearance is similar to that of a notebook computer, but it has an additional function of switching signal sources.

[0003] Generally, the LCD KVM switch is installed on the slide rail of a cabinet. When not in use, the screen covers the keyboard base in a closed state. When the user needs to operate, the switch can be pulled out along the slide rail and the screen can be lifted. However, during the process of pulling out the switch, the screen may be lifted due to the large height difference between the user's height and the installation height of the switch in the cabinet, which affects the safety and stability of the pulling process. Although a torsion spring with a large torsion force can be set on the hinge between the screen and the keyboard base to avoid the above situation, after the switch is pulled out and positioned, the user needs to apply enough force to lift the screen, which is not conducive to operation and is easy to sprain the wrist. In addition, the torsion spring with a large torsion force is likely to make the screen unable to close completely and hang in the air, which is not conducive to the product competitiveness. Summary of the Invention

[0004] According to some embodiments of the present disclosure, an electronic device includes a base, a screen module, and a screen locking module. The screen module has a positioning portion. The base is pivotally connected to the screen module and is configured to move along a pulling-out direction with a slide rail. The screen locking module is disposed on the base and includes a first positioning block. The first positioning block is movably connected to the base and has an engaging portion for engaging with the positioning portion. The moving direction of the first positioning block is perpendicular to the pulling-out direction. When the electronic device is in a storage position, the screen module is closed towards the base and the engaging portion engages with the positioning portion. When the base is moved from the storage position along the pulling-out direction to a use position, the first positioning block is pushed by a pushing portion of the slide rail and moves towards the base, so that the engaging portion does not engage with the positioning portion. When the electronic device is moved from the use position along a pushing-in direction opposite to the pulling-out direction, the pushing portion does not push the first positioning block. At this time, the first positioning block moves away from the base, so that the engaging portion engages with the positioning portion.

[0005] In some embodiments, the electronic device further includes a screen pressing module disposed on the base and including a pressing portion and a first abutting portion. The pressing portion protrudes from the top surface of the base, and the pressing portion is movably connected to the base, wherein the moving direction of the pressing portion is perpendicular to the pulling-out direction and the moving direction of the first positioning block. The first abutting portion abuts against the bottom surface of the pressing portion and the first slider of the screen locking module, wherein the first slider is movably connected to the base, and one moving direction of the first slider is parallel to the pulling-out direction, and the first positioning block is movably connected to the first slider. When the screen module is lifted, the pressing portion rises to cause the first slider to move in the pulling-out direction along with the first abutting portion.

[0006] In some embodiments, the electronic device further includes a slide rail releasing module. The slide rail releasing module is located in the base and includes a second slider and a second positioning block, wherein the second slider is movably connected to the base, the moving direction of the second slider is parallel to the pulling-out direction, the second positioning block is movably connected to the second slider and protrudes from the side wall of the base, and the moving direction of the second positioning block is the same as the moving direction of the first positioning block.

[0007] In some embodiments, the screen pressing module further includes a second abutting portion. The second abutting portion abuts against the second slider and the bottom surface of the pressing portion, wherein when the screen module is lifted, the pressing portion rises to cause the second slider to move in the pushing-in direction along with the second abutting portion, so that the second positioning block protrudes toward the slide rail to limit the positioning piece of the slide rail.

[0008] In some embodiments, the first abutting portion and the second abutting portion are pivotally connected to the base, and the first abutting portion and the second abutting portion are separated.

[0009] In some embodiments, the first abutting portion and the second abutting portion are of an integrally formed structure.

[0010] In some embodiments, when the screen module is closed, the pressing portion is pressed into the base by the screen module, causing the first abutting portion and the second abutting portion to pivot and respectively causing the first slider and the second slider to move away from the pressing portion, so that the second positioning block and the positioning piece of the slide rail at least partially overlap to release the limit.

[0011] In some embodiments, the electronic device further includes a plurality of springs. The springs are respectively located between the first positioning block and the first slider, between the second positioning block and the second slider, between the first slider and the base, between the second slider and the base, and between the pressing portion and the base.

[0012] According to some embodiments of the present disclosure, a multi-computer switching device includes a cabinet and an electronic device. The cabinet has slide rails. The electronic device is located on the cabinet and includes a base, a screen module, and a screen locking module. The screen module has a positioning portion. The base is pivotally connected to the screen module and configured to move along the pulling-out direction with the slide rails. The screen locking module is disposed on the base and includes a first positioning block. The first positioning block is movably connected to the base and has an engaging portion for engaging with the positioning portion. The moving direction of the first positioning block is perpendicular to the pulling-out direction. When the electronic device is in the storage position, the screen module closes towards the base and the engaging portion engages with the positioning portion. When the base is moved from the storage position along the pulling-out direction to the use position, the first positioning block is pushed by the pushing portion of the slide rail and moves towards the base, causing the engaging portion not to engage with the positioning portion. When the electronic device is moved from the use position along the pushing-in direction opposite to the pulling-out direction, such that the pushing portion does not push the first positioning block, at this time the first positioning block moves away from the base, causing the engaging portion to engage with the positioning portion.

[0013] In some embodiments, the electronic device further includes a screen pressing module. The screen pressing module is disposed on the base and includes a pressing portion and a first abutting portion. The pressing portion is located at the edge of the base adjacent to the slide rail and protrudes from the top surface of the base. The pressing portion is movably connected to the base, wherein the moving direction of the pressing portion is perpendicular to the pulling-out direction and the moving direction of the first positioning block. The first abutting portion abuts against the bottom surface of the pressing portion and a first slider of the screen locking module, wherein the first slider is movably connected to the base, and a moving direction of the first slider is parallel to the pulling-out direction, and the first positioning block is movably connected to the first slider. When the screen module is lifted, the pressing portion rises, causing the first slider to move in the pulling-out direction along with the first abutting portion.

[0014] In the above-described embodiments of the present disclosure, since the electronic device has a screen locking module, the first positioning block of the screen locking module is movably connected to the base, and the moving direction of the first positioning block is perpendicular to the pulling-out direction. Therefore, when the base moves from the storage position to the use position along the pulling-out direction, the first positioning block can be compressed by the pushing portion of the slide rail. In this way, the first positioning block of the screen locking module will move inward in the direction approaching the base, so that the engaging portion of the first positioning block does not engage with the positioning portion of the screen module, thereby releasing the screen module and enabling it to be lifted. In addition, when the electronic device is moved from the use position in the pushing-in direction, the pushing portion does not push the first positioning block of the screen locking module. At this time, the first positioning block moves outward in the direction away from the base, so that the engaging portion of the first positioning block engages with the positioning portion of the screen module, thereby locking the screen module and preventing it from being lifted. Through the above design, it is possible to prevent the screen module from being lifted due to the large height difference between the user's height and the installation height of the electronic device in the cabinet during the process of pulling out and pushing in the electronic device, and the safety and stability of the pulling-out and pushing-in processes can be improved. In addition, the electronic device can omit the torsion spring with a large torque for the hinge (Hinge), and when the screen module is in the use position, the user can easily lift it to avoid spraining the wrist, and it can be completely closed during the pulling-out and pushing-in processes to avoid suspension, which is beneficial to the product competitiveness.

[0062] Figure 1The present invention shows a three-dimensional diagram of a multi-computer switching device 200 according to an embodiment of the present invention. The multi-computer switching device 200 includes a cabinet 210 and an electronic device 100. The cabinet 210 has a slide rail 220. The electronic device 100 is located on the cabinet 210 and connected to the slide rail 220, so that the electronic device 100 can be moved from the cabinet 210 to the electronic device 100. Figure 1 The storage position moves along the pull-out direction D1 with the slide rail 220. In some embodiments, the electronic device 100 may be a keyboard-video-mouse switch (LCD KVM switch) or a laptop computer equipped with a liquid crystal display (such as a screen module 120). The base 110 may include components such as a keyboard, a processor, a memory, a hard disk, and a connector. The electronic device 100 includes a base 110 and a screen module 120. The base 110 may move along the pull-out direction D1 with the slide rail 220. The screen module 120 is pivotally connected to the base 110.

[0063] Figure 2 Show Figure 1 A three-dimensional diagram of internal components of area A of the electronic device 100. Figure 3 Show Figure 1 A cross-sectional view of the electronic device 100 along line segment 3 - 3 . Figure 2 and Figure 3 The electronic device 100 is Figure 1 The state of the internal components in the stowed position. Figure 2 and Figure 3 The electronic device 100 includes a screen locking module 130, a screen pressing module 140, and a slide rail releasing module 150. The screen locking module 130 is disposed on the base 110 and includes a first positioning block 132. In the following description, the configuration of the screen locking module 130 is a telescopic moving implementation. The first positioning block 132 is movably connected to the base 110, for example, by a spring S1. The moving direction D2 of the first positioning block 132 is different from the pulling direction D1 (see Figure 1 ) is vertical. The screen module 120 has a positioning portion 122. The first positioning block 132 of the screen locking module 130 has a locking portion 133 that can be engaged with the positioning portion 122. In this embodiment, the screen module 120 may include an opening O for the locking portion 133 of the screen locking module 130 to pass through. It should be noted that the configuration of the aforementioned screen locking module is not limited to this, and may also be a pivotally movable embodiment, or other embodiments that can achieve the same effect.

[0064] Figure 3 For Figure 1 The cross-section diagram from the lower right to the upper left shows that the slide rail 220 has a push portion 221 . Figure 3 The push portion 221 is located in front of the first positioning block 132, that is, locatedFigure 1 The lower right of area A. When the electronic device 100 is in Figure 1 the storage position and before the electronic device 100 moves in the pulling-out direction D1 to Figure 4 the use position, the screen module 120 faces the base 110 and closes, and the engaging portion 133 of the first positioning block 132 engages with the positioning portion 122 of the screen module 120. In this state, the first positioning block 132 outside the side wall 112 of the base 110 does not push against the pushing portion 221 of the slide rail 220, and the pushing portion 221 is located in front of the first positioning block 132 and at least partially overlaps in the pulling-out direction D1.

[0065] Figure 4 Shows Figure 1 a perspective view of the electronic device 100 when it moves in the pulling-out direction D1 to the use position. Figure 5 Shows Figure 4 a perspective view of the internal components of the electronic device 100 when it is in the use position. When the base 110 is moved from the storage position in the pulling-out direction D1 to the use position, the first positioning block 132 will touch the pushing portion 221 of the slide rail 220, causing the first positioning block 132 to be pushed by the pushing portion 221 of the slide rail 220 and move in the direction closer to the base 110. That is to say, the first positioning block 132 compresses the spring S1 and retracts.

[0066] Figure 6 Shows Figure 4 a sectional view of the electronic device 100 when it is in the use position. Figure 5 And Figure 6 are the states of the internal components of the electronic device 100 when it is in Figure 4 the use position. Referring to Figure 5 and Figure 6 simultaneously, in this state, since the first positioning block 132 is pushed by the pushing portion 221 of the slide rail 220 and moves in the direction closer to the base 110, the engaging portion 133 of the first positioning block 132 will move from Figure 3 its position to the left to Figure 6 its position, so that the engaging portion 133 of the first positioning block 132 does not engage with the positioning portion 122 of the screen module 120. That is to say, the engaging portion 133 is separated from the hook-shaped positioning portion 122, thereby releasing the screen module 120, enabling the screen module 120 to be lifted in the direction D5 and pivot on the base 110, as shown in Figure 7 the electronic device 100 shown.

[0067] Figure 8 Shows Figure 7 a partial enlarged view of the screen module 120 of the electronic device 100 when it is lifted. Figure 9 Shows Figure 7 a perspective view of the internal components of the electronic device 100 when the screen module 120 is lifted. Referring to Figure 8With Figure 9 , the screen pressing module 140 is disposed on the base 110 and includes a pressing portion 142, a first abutting portion 144, and a second abutting portion 146. In the following description, an embodiment in which the screen pressing module 140 is pivotally movable is described. The pressing portion 142 is movably connected to the base 110, for example, connected by a spring S2. The moving direction D3 of the pressing portion 142 is perpendicular to the pulling-out direction D1 and the moving direction D2 of the first positioning block 132. The first abutting portion 144 and the second abutting portion 146 are pivotally connected to the base 110 by a torsion spring, and the first abutting portion 144 and the second abutting portion 146 are separated. In addition, the screen locking module 130 has a first slider 134, and the first abutting portion 144 abuts against the bottom surface of the pressing portion 142 and the first slider 134. The first slider 134 is movably connected to the base 110, for example, connected by a spring S31. The moving direction D4 of the first slider 134 is parallel to the pulling-out direction D1, and the first positioning block 132 is movably connected to the first slider 134, for example, connected by a spring S1. It should be noted that the above-described configuration of the screen pressing module is not limited thereto, and may also be an embodiment of telescopic movement, or other embodiments that can achieve the same effect.

[0068] The slide rail release module 150 is located in the base 110 and includes a second slider 152 and a second positioning block 154. The second slider 152 is movably connected to the base 110, for example, connected by a spring S32. The moving direction D4 of the second slider 152 is parallel to the pulling-out direction D1. The second positioning block 154 is movably connected to the second slider 152 and protrudes from the side wall 112 of the base 110, for example, connected by a spring S4. The moving direction D2 of the second positioning block 154 is the same as the moving direction D2 of the first positioning block 132. The second abutting portion 146 of the screen pressing module 140 abuts against the second slider 152 and the bottom surface of the pressing portion 142.

[0069] In this embodiment, the spring S1 is located between the first positioning block 132 and the first slider 134, the spring S2 is located between the pressing portion 142 and the base 11, the spring S31 is located between the first slider 134 and the base 110, the spring S32 is located between the second slider 152 and the base 110, and the spring S4 is located between the second positioning block 154 and the second slider 152. In the following description, the operating mechanisms of the screen locking module 130, the screen pressing module 140, and the slide rail release module 150 will be described in detail.

[0070] Refer to simultaneously Figure 5 With Figure 9 , when the pressing portion 142 is pressed by the screen module 120 (see Figure 1 , Figure 4)When the covering is pressed, the position will drop and retract inside the top surface of the base 110. At this time, the side of the first abutting portion 144 away from the pressing portion 142 pushes away from the first slider 134, and the side of the second abutting portion 146 away from the pressing portion 142 pushes away from the second slider 152, as Figure 5 shown. When the screen module 120 is lifted, the pressing portion 142 rises and protrudes upward from the top surface of the base 110 (as Figure 8 shown), at this time, the side of the first abutting portion 144 away from the pressing portion 142 and the side of the second abutting portion 146 away from the pressing portion 142 both move inward due to pivoting, causing the first slider 134 to move in the pulling-out direction D1 along with the first abutting portion 144, and the second slider 152 to move in the direction opposite to the pulling-out direction D1 (i.e., the pushing-in direction D7) along with the second abutting portion 146. That is to say, when the screen module 120 is lifted and the pressing portion 142 rises, both the first slider 134 and the second slider 152 move towards the pressing portion 142, Figure 9 the distance between the first slider 134 and the second slider 152 is less than Figure 5 the distance between the first slider 134 and the second slider 152.

[0071] In some embodiments, the pressing portion 142 can be located at the edge of the base 110 adjacent to the slide rail 220, avoiding accidental touch by the user when operating the electronic device 100, and can effectively link the lifting and closing of the screen module 120. In some other embodiments, the first abutting portion 144 and the second abutting portion 146 of the screen pressing module 140 are not limited to this. The first abutting portion and the second abutting portion can be an integrally formed trapezoidal structure. For example, the first abutting portion is the left half of the trapezoidal structure, and the second abutting portion is the right half of the trapezoidal structure, and the same effect can also be achieved.

[0072] Figure 10 Shown Figure 8 Another perspective when the screen module 120 of the electronic device 100 shown is lifted. Referring to Figure 9 and Figure 10 simultaneously, when the screen module 120 is lifted and the pressing portion 142 rises, since the second slider 152 moves towards the pressing portion 142, the second slider 152 can move from Figure 5 the position blocked by the positioning piece 222 of the slide rail 220 to Figure 9 the position, enabling the second positioning block 154 to protrude towards the slide rail 220 to limit the positioning piece 222 of the slide rail 220. In this state, the positioning piece 222 of the slide rail 220 is stuck by the second positioning block 154, fixing the slide rail 220 and preventing it from sliding in the pushing-in direction D7.

[0073] Figure 11 Shown Figure 7 A perspective view of the electronic device 100 when the screen module 120 is closed. Figure 12 ShownFigure 11 Stereoscopic view of internal components when the screen module 120 of the electronic device 100 is closed. Refer also to Figure 11 and Figure 12 , when the screen module 120 is closed in the direction D6 (see Figure 7 ), the pressing portion 142 will be pressed into the base 110 by the screen module 120. Therefore, the position of the pressing portion 142 will drop and retract inside the top surface of the base 110, and the drop of the pressing portion 142 can cause the first abutting portion 144 and the second abutting portion 146 to pivot, respectively causing the first slider 134 and the second slider 152 to move away from the pressing portion 142. That is to say, the side of the first abutting portion 144 away from the pressing portion 142 pushes away the first slider 134, and the side of the second abutting portion 146 away from the pressing portion 142 pushes away the second slider 152. Through the above operations, the screen locking module 130, the screen pressing module 140 and the slide rail release module 150 return to Figure 5 the state, and the second positioning block 154 will at least partially overlap with the positioning piece 222 of the slide rail 220 (see Figure 5 ), and the limit is released, enabling the slide rail 220 to slide.

[0074] Next, when the screen module 120 is closed and the electronic device 100 moves in the pushing direction D7 opposite to the pulling direction D1 from the use position, the pushing portion 221 of the slide rail 220 does not push against the first positioning block 132. At this time, the first positioning block 132 moves away from the base 110. That is to say, the first positioning block 132 protrudes outward due to the reset of the spring S1. Therefore, the first positioning block 132 returns from Figure 6 the state to Figure 3 the state, thereby locking the screen module 120 so that it cannot be lifted, as shown in Figure 3 . In this way, when the screen module 120 is closed and the base 110 moves along the slide rail 220 in the pulling direction D1 or the pushing direction D7, as long as the electronic device 100 does not reach the use position of the pushing portion 221, the screen module 120 will remain closed and cannot be lifted, which is beneficial to safety.

[0075] With the above design, it is possible to prevent the screen module 120 from being lifted when the user pulls out and pushes in the electronic device 100 due to a large difference between the user's height and the installation height of the electronic device 100 in the cabinet 210, thereby improving the safety and stability during the pulling-out and pushing-in processes. Additionally, through the interlocking between the pressing portion 142 of the screen pressing module 140 and the second positioning block 154 of the slide rail release module 150 when the screen module 120 is lifted and closed, the second positioning block 154 can limit the positioning piece 222 of the slide rail 220 when the screen module 120 is lifted, achieving the technical effect of locking the slide rail 220 and preventing the electronic device 100 from sliding at the usage position. Moreover, the second positioning block 154 can release the positioning piece 222 of the slide rail 220 when the screen module 120 is closed, achieving the technical effect of releasing the slide rail 220.

[0076] In addition, the electronic device 100 can omit the torsion spring with a large torque for the hinge, and when the screen module 120 is in the usage position, it allows the user to easily lift it without spraining the wrist, while it can be fully closed during the pulling-out and pushing-in processes to avoid suspension, which is beneficial to the product competitiveness. The electronic device 100 can be applied to single-hand release single-slide rail models and large-size screen module 120 models.

[0077] The foregoing has outlined the features of several embodiments, enabling those skilled in the art to better understand the aspects of the present disclosure. Those skilled in the art should understand that they can easily use the present disclosure as a basis for designing or modifying other processes and structures to achieve the same purposes and / or the same advantages as the embodiments described herein. Those skilled in the art should also recognize that such equivalent structures do not depart from the concept and scope of the present disclosure, and various changes, substitutions, and alterations can be made herein without departing from the concept and scope of the present disclosure.
