Description

Technical Field

[0001] This invention relates to a lifting mechanism, and more particularly to a lifting mechanism applicable to a display device. Background Technology

[0002] In current display devices with height adjustment functions, there is a problem where the screen automatically slides down and cannot be hovered when there are additional objects installed or placed on it. This is known as a malfunction of the hovering function, which is inconvenient for users to place headphones, webcams, or screen lights on such display devices. Therefore, there is an urgent need for a new display device to solve the above problem. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides a lifting mechanism and a display device using the same, in order to improve the problems existing in the prior art.

[0004] According to one aspect of the present invention, a lifting mechanism is provided, which is suitable for mounting on a support frame of a display device. This lifting mechanism includes a lifting base, a stop, a trigger, and an elastic member. The stop is disposed in the lifting base. The trigger is movably connected to the lifting base. The elastic member is connected to the lifting base and the stop. Corresponding to the trigger being driven to move the stop, the stop moves to press against the inner wall surface of the support frame, and the lifting base is positioned within the support frame. Corresponding to the trigger being driven to release the stop, the stop moves away from the inner wall surface of the support frame by the restoring force of the elastic member, and the lifting base is movable up and down within the support frame.

[0005] Preferably, the lifting mechanism further includes a fixing member. One end of the fixing member is connected to the lifting base, wherein the elastic member is annularly disposed on the fixing member, one end of the elastic member abuts against the fixing member, and the other end of the elastic member is fixed to the stop member.

[0006] Preferably, the lifting base has a protrusion, and when the trigger is driven to move the stop, the trigger passes through the protrusion and is limited to being located between the protrusion and the stop.

[0007] Preferably, when the trigger is driven to release the stop, the trigger passes through the protrusion and abuts against the protrusion.

[0008] Preferably, the trigger is pivotally connected to the lifting base so as to be driven to pivotally rotate and drive the stop.

[0009] Preferably, it also includes a positioning platform connected to the lifting base. The positioning platform includes a groove, and when the trigger is driven to move the stop, the trigger is positioned in the groove.

[0010] Preferably, the trigger is exposed from the support frame.

[0011] According to another aspect of the present invention, a display device is provided, comprising a display screen, a support frame, and a lifting mechanism. The support frame includes a slide rail and a constant-force elastic member. The lifting mechanism is movably disposed on the support frame. The lifting mechanism includes a lifting base, a stop, a trigger, and an elastic member. The lifting base is disposed on the slide rail and connected to the display screen and the constant-force elastic member. The constant-force elastic member provides a supporting force sufficient to support the weight of the display screen. The stop is disposed in the lifting base. The trigger is movably connected to the lifting base. The elastic member is connected to the lifting base and the stop. Corresponding to the trigger being driven to actuate the stop, the stop moves to press against the inner wall surface of the support frame, and the lifting base is positioned within the support frame, thereby allowing the lifting mechanism to additionally bear a load besides the weight of the display screen. Furthermore, corresponding to the trigger being driven to release the stop, the stop moves away from the inner wall surface of the support frame by the restoring force of the elastic member, and the lifting base is movably displaced within the support frame.

[0012] Preferably, the lifting mechanism further includes a fixing member, one end of which is connected to the lifting base, wherein the elastic member is arranged around the fixing member, one end of which abuts against the fixing member, and the other end of which is fixed to the stop member.

[0013] Preferably, the lifting base has a protrusion, and when the trigger is driven to move the stop, the trigger passes through the protrusion and is limited to being located between the protrusion and the stop.

[0014] Preferably, when the trigger is driven to release the stop, the trigger passes through the protrusion and abuts against the protrusion.

[0015] Preferably, the trigger is pivotally connected to the lifting base so as to be driven to pivotally rotate and drive the stop.

[0016] Preferably, the lifting mechanism further includes a positioning platform connected to the lifting base. The positioning platform includes a groove, and when the trigger is driven to move the stop, the trigger is positioned in the groove.

[0017] Preferably, the trigger element protrudes from the support frame.

[0018] Compared with the prior art, the lifting mechanism and display device having the lifting mechanism proposed in this invention can suspend the display screen without additional load relative to the support frame in the first state (i.e., free state) of the lifting mechanism, and can also suspend the display screen with additional load relative to the support frame in the second state (i.e., locked state) of the lifting mechanism. Therefore, the lifting mechanism and display device having the present invention can solve the problem of suspension function failure in the prior art.

[0026] To provide a further understanding of the purpose, structure, features and functions of the present invention, detailed descriptions are provided below with reference to embodiments.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram illustrating the display device 10 according to an embodiment of the present disclosure is shown. Figure 2 and Figure 3 A side view of the display device 10 according to an embodiment of the present disclosure is shown.

[0028] The display device 10 proposed according to the present invention may be, but is not limited to, a monitor suitable for desktop computers. It includes a support frame 11 and a display screen (not shown) connectable to the support frame 11 via a connection interface 11V, such as a VESA interface. The support frame 11 includes a slide rail 11R, along which the display screen can slide longitudinally to change its position, allowing the user to adjust it to the optimal viewing position. The support frame 11 further includes a constant-force elastic element 11S, which may be, but is not limited to, a constant-force spring. The constant-force elastic element 11S provides sufficient support force to support the weight of the display screen, allowing the display screen to be positioned at multiple locations along the path of the slide rail 11R without sliding down to the bottom. It should be noted that the constant-force elastic element 11S is only sufficient to support the weight of the display screen; if additional load is applied to the display screen, the display screen may slide down along the path of the slide rail 11R. Therefore, the display device 10 disclosed in this embodiment further includes a lifting mechanism.

[0029] Please refer to the above as well. Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 4 A partial illustration of the lifting mechanism 100 of the display device 10 in its first state. Figure 5 A partial illustration shows a schematic diagram of the lifting mechanism 100 of the display device 10 in a second state. The structural configuration of the lifting mechanism 100 is shown to be clearly illustrated. Figure 4 and Figure 5 The aforementioned connection interface 11V is omitted from the drawing. Figure 6 A schematic diagram of the lifting mechanism 100 of the perspective drawing display device 10 in its first state. Figure 7 A perspective view of the lifting mechanism 100 of the display device 10 in its second state.

[0030] To accommodate situations where the load supported by the support frame 11 exceeds the weight of the display screen, such as when other objects (e.g., headphones, video cameras, or screen lights) are present on the display screen, the display device 10 further includes a lifting mechanism 100. This allows the display screen to be suspended at multiple positions along the path of the slide rail 11R even under additional load. The lifting mechanism 100 is vertically detachable from the support frame 11. The lifting mechanism 100 mainly includes a lifting base 110, a stop 120, a trigger 130, and a spring 140.

[0031] The lifting base 110 is mounted on the slide rail 11R and can be connected to the constant-force elastic member 11S. The lifting base 110 can be connected to a display screen through a connection interface 11V, wherein the connection interface 11V is preferably pivotally connected to the lifting base 110, so that the display screen can rotate relative to the support frame 11 to change the angle of its display surface. The trigger member 130 is movably connected to the lifting base 110. As before Figure 2 and Figure 3 As shown, the trigger 130 can protrude from the support frame 11 for the user to actuate, thereby switching the lifting mechanism 100 between different first and second states. In one embodiment, the trigger 130 may have a grip portion made of soft material to provide the user with a better grip feel.

[0032] Figure 2 and Figure 4 The corresponding lifting mechanism 100 is in the first state, that is, the lifting mechanism 100 is in the free state. In this free state, the lifting mechanism 100 can bear the weight of the display screen itself by means of the constant force elastic element 11S, so that the position of the display screen will not drop. Figure 3 and Figure 7 This corresponds to the second state of the lifting mechanism 100, i.e., the lifting mechanism 100 is in the locked state. When the constant force elastic member 11S alone cannot support the weight of the display screen itself and the additional load applied to it, the lifting mechanism 100 can be switched to the locked state to prevent the position of the display screen from falling. The following will explain how the locking mechanism of the lifting mechanism 100 suspends the display screen with additional load.

[0033] like Figure 6 As shown, the lifting mechanism 100 is in the first state, the trigger 130 is far away from the support frame 11, and the stop 120 is disposed in the lifting base 110 and spaced apart from the inner wall surface 11W of the support frame 11 by a gap D. This corresponds to the free state of the aforementioned lifting mechanism 100, that is, the display screen without any object is able to slide up and down to be suspended at any position on the path of the slide rail 11R.

[0034] like Figure 7As shown, when the display screen has additional load applied to it (e.g., headphones, video cameras, or screen lights are mounted on it), the trigger 130 can be pulled down to press against and move the stop 120. For example, the trigger 130 is pivotally connected to the lifting base 110 to be driven to pivot and move the stop 120. Then, the stop 120 moves the aforementioned gap D distance to press against the inner wall surface 11W of the support frame 11. Thus, the friction provided by the stop 120 pressing against the support frame 11, combined with the structural engagement provided by the stop 120 being disposed in the lifting base 110, can switch the lifting mechanism 100 to the locked state to suspend the display screen with additional load. In other words, in response to the trigger 130 being driven to move the stop 120, the stop 120 moves to press against the inner wall surface 11W of the support frame 11, thereby positioning the lifting base 110 within the support frame 11. This allows the lifting mechanism 100 to bear additional loads beyond the weight of the display screen. In one embodiment, a pressing portion of the stop 120 that presses against the inner wall surface 11W of the support frame 11 may be made of a wool or velvet material to further increase the friction between the stop 120 and the inner wall surface 11W, thereby stabilizing the suspension of the display screen.

[0035] Furthermore, when switching the lifting mechanism 100 from the locked state to the free state, the trigger 130 can be pulled upward to release the stop 120. The elastic member 140 (which may be, but is not limited to, a spring) is connected to the lifting base 110 and the stop 120 to provide a restoring force for the stop 120 to reset, causing the stop 120 to move toward the lifting base 110 and away from the inner wall surface 11W of the support frame 11, until the stop 120 returns to its original position. Figure 6 The state of the gap D between the lifting base 110 and the inner wall surface 11W of the support frame 11 is shown. In other words, corresponding to the trigger 130 being driven to release the stop 120, the stop 120 can be moved away from the inner wall surface 11W of the support frame 11 by the restoring force of the elastic member 140, so that the lifting base 110 can be raised and lowered within the support frame 11. As described above, by driving the trigger 130, the lifting mechanism 100 can be switched between a free state and a locked state to achieve the raising and lowering of the display screen position and the suspension of the display screen. In particular, in the locked state of the lifting mechanism 100, a display screen with additional load can be suspended. In one embodiment, through the setting of the lifting mechanism 100, the display device 10 disclosed herein can support an additional load of about 2 kilograms (kg).

[0036] In addition, such as Figure 6 and Figure 7As shown, the lifting mechanism 100 further includes a fixing member 150, which may be, but is not limited to, a screw element. One end of the fixing member 150 is connected to the lifting base 110. An elastic member 140 is arranged around the fixing member 150, with one end of the elastic member 140 abutting against the fixing member 150, and the other end of the elastic member 140 fixed to the stop member 120. Thus, the fixing member 150 can be connected between the lifting base 110, the stop member 120, and the elastic member 140 to provide positioning for the internal structure.

[0037] In addition, such as Figure 4 and Figure 5 As shown, protrusions 111 may be provided on both sides of the lifting base 110. When the trigger 130 is driven to move the stop 120, the trigger 130 passes through the protrusions 111 and is confined between the protrusions 111 and the stop 120. In other words, when the lifting mechanism 100 is in the locked state, the protrusions 111 can confine the trigger 130 in the support frame 11 to provide a fixing effect, which can prevent the lifting mechanism 100 from switching to the free state due to accidental drive of the trigger 130, thus preventing the lifting base 110 from falling unexpectedly. In addition, the protrusions 111 can provide a slight tactile feedback when the trigger 130 passes through them, so that the user can confirm that the lifting mechanism 100 has completed the switch between the free state and the locked state. Furthermore, when the lifting mechanism 100 is switched from the locked state to the free state, that is, when the trigger 130 is driven to release the stop 120, the trigger 130 passes through the protrusion 111 and abuts against the protrusion 111. Thus, the protrusion 111 provides a stopping point for the trigger 130 in the free state of the lifting mechanism 100, which can prevent the lifting mechanism 100 from being unexpectedly switched to the locked state due to accidental drive of the trigger 130, so that the lifting base 110 cannot be smoothly raised and lowered within the support frame 11.

[0038] In addition, such as Figure 4 and Figure 5 As shown, the lifting mechanism 100 further includes a positioning platform 160, which is connected to the lifting base 110 and can be raised and lowered synchronously with the lifting base 110. The positioning platform 160 may include a groove 161, in which the trigger member 130 is positioned after being driven to move the stop member 120. Specifically, the trigger member 130 and the groove 161 may be magnetically connected, so that the trigger member 130 can be magnetically fixed in the groove 161, thereby further restricting the movement of the trigger member 130 in the locked state of the lifting mechanism 100, thus preventing the lifting mechanism 100 from unexpectedly switching from the locked state to the free state due to accidental driving of the trigger member 130.

[0039] In summary, the display device with a lifting mechanism proposed in this invention can suspend the display screen without additional load relative to the support frame in the first state (i.e., free state) of the lifting mechanism, and can also suspend the display screen with additional load relative to the support frame in the second state (i.e., locked state) of the lifting mechanism. Therefore, the lifting mechanism and the display device having it disclosed herein can solve the problem of suspension function failure in the prior art.

[0040] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
