Description

Technical Field

[0001] The present invention relates to the field of lifting devices, and in particular to a lifting device capable of adjusting a fixed force and a display device comprising the same. Background Art

[0002] The demand for mounting accessories for display devices is becoming increasingly prominent. Many users will add additional baffles, lamps, camera modules or other accessories to the display screen based on personal preferences or work needs. Traditional lifting bases can usually only adapt to the weight of a single screen of specific specifications. Once the user installs a heavier display on the lifting base, or mounts other electronic devices on the display screen, it is very easy to cause the base or screen to shake or tilt unexpectedly during the lifting process due to excessive load.

[0003] In the current conventional technology, in order to prevent the base or the screen from shaking or tilting during the lifting process, multiple friction plates are often added between the upper and lower brackets when designing the lifting base to increase the friction; however, in this way, when the display screen is not attached with an additional load or has a low load, when the user adjusts the screen height, he will feel greater resistance or poor operating feel, making the adjustment process laborious.

[0004] Therefore, it is necessary to design a new type of supporting device and display device to improve the above defects. Summary of the invention

[0005] The purpose of the present invention is to provide a support device that can be applied to objects of different weights (such as display screens). When the weight of the object is light, only the first elastic member provides the necessary elastic support, so that the lifting seat has a good operating feel when adjusting the height. When the weight of the object is heavy or other accessories are additionally mounted on the object, the first and second elastic members jointly generate elastic force, so that the lifting seat can stably support the heavier object, avoid unexpected shaking or tilting, and have better versatility.

[0046] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0047] Certain words are used in the specification and claims to refer to specific components. Those with ordinary knowledge in the field should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but rather use differences in components' functions as the criteria for distinction. The term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".

[0048] Please refer to Figure 1-Figure 3 as well as Figure 5-Figure 6 , Figure 1 This is a schematic diagram of the assembly between the support bracket and the lifting seat of the supporting device according to one embodiment of the present invention. Figure 2 for Figure 1 Schematic diagram of the cross-section structure from the AA direction, Figure 3 for Figure 2 A schematic diagram of the local enlarged structure of the B area in the middle. Figure 5 For the present invention Figure 1 Schematic diagram of the local explosion structure, Figure 6 It is a schematic diagram of the structure of the locking member and the positioning block of the supporting device.

[0049] The supporting device comprises a support 1, a lifting seat 2, a locking member 3, a first elastic member 4 and a second elastic member 5. The lifting seat 2 is used to support an object. The lifting seat 2 is slidably arranged on the support 1 along a first direction D1. In this embodiment, the lifting seat 2 is lifted and moved by the slide rail of the support 1. In practice, the support 1 can be connected to a base and can be stably placed on a plane. The first elastic member 4 is arranged on the lifting seat 2 and has a first stretching end portion. The first stretching end portion is fixedly connected to the support 1, that is, the first elastic member 4 is connected between the support 1 and the lifting seat 2. When the lifting seat 2 is lifted and moved relative to the support 1 along the first direction D1, the first elastic member 4 generates an elastic force to provide the lifting seat 2 with the necessary elastic support.

[0050] The second elastic member 5 is arranged on the lifting seat 2 and has a second stretching end 51, and the second stretching end 51 is fixedly provided with a first connecting structure; the locking member 3 is arranged on the bracket 1 and has a second connecting structure, and the locking member 3 corresponds to the second stretching end 51 of the second elastic member 5, and can be selectively set at one of the first position and the second position.

[0051] Among them, the user can operate the locking member 3 to switch between different elastic support modes to adjust the elastic support force of the support device to adapt to objects of different weights. In this embodiment, the object is a display screen as an example, but it is not limited to this. Specifically, when the user operates the locking member 3 to move to the first position, the second connection structure of the locking member 3 is connected and fixed with the first connection structure configured at the second stretching end 51, so that the bracket 1 is locked and connected with the second elastic member 5. The first elastic member 4 and the second elastic member 5 jointly provide the elastic force of the lifting seat 2 to elastically support the bracket 1, thereby ensuring that the lifting seat 2 can stably support a display screen with a heavier weight or additional heavy accessories (such as a sunshade, a camera, a clamp light, etc.), and avoid unexpected shaking or tilting of the lifting seat 2 and the display screen mounted thereon. When the locking member 3 is operated to move to the second position, the second connecting structure is separated from the first connecting structure (i.e., the locking member 3 is separated from the second stretching end 51 of the second elastic member 5), so that the bracket 1 is separated from the second elastic member 5, and the second elastic member 5 and the second connecting structure move up and down with the lifting seat 2. At this time, only the first elastic member 4 provides the necessary elastic force for the elastic support of the lifting seat 2 relative to the bracket 1. The lifting seat 2 can stably support a display screen without additional accessories or a light weight, and the user can adjust the height of the lifting seat 2 more easily and smoothly, with a good operating feel.

[0052] The supporting device provided by the present invention has a simple structure, and different elastic supporting modes can be switched by simply operating the locking member 3, thereby adjusting the elastic supporting force of the supporting device to adapt to objects of different weights, thereby meeting the personalized needs of different users and having good practicality.

[0053] Furthermore, the first elastic member 4 in the supporting device of the present invention has at least one constant force spring, and the second elastic member 5 is preferably a constant force spring, so as to provide continuous and uniform supporting force when the lifting seat 2 supports objects of different weights, thereby ensuring the stability and smoothness of the lifting seat 2 during the lifting process.

[0054] Reference Figure 3 and Figure 4As shown, in one embodiment, the support device further comprises a fixing seat 6, and the fixing seat 6 has a protrusion 61. A groove 61' matching with the protrusion 61 is provided on the lifting seat 2, and the protrusion 61 and the groove 61' are detachably plugged in the second direction D2. When the first plug-in portion is inserted into the second plug-in portion, the protrusion 61 is arranged in the groove 61' and tightly matches with the groove 61' in the first direction D1, so as to realize the fixed connection between the fixing seat 6 and the lifting seat 2 in the first direction D1; wherein, the protrusion 61 is, for example, a T-shaped protrusion, and the groove 61' is, for example, a T-shaped groove matching with the T-shaped protrusion, but the present invention is not limited thereto. A receiving groove S is provided in the fixing seat 6, and the second elastic member 5 comprises a second winding end 50 and a second stretching end 51, the second winding end 50 is arranged in the receiving groove S, and the second stretching end 51 extends from the receiving groove S. Thus, by means of the fixed base 6 , the second elastic member 5 can be easily disassembled from the lifting base 2 and can be easily replaced and maintained.

[0055] In some other embodiments, the supporting device further comprises a fixing seat 6', the fixing seat 6' is locked and fixed (for example, screwed) on the lifting seat 2, the fixing seat 6' is also provided with a receiving groove, the first elastic member 4 comprises a first winding end and a first stretching end, the first winding end of the first elastic member 4 is arranged in the receiving groove, the first stretching end extends from the receiving groove and is fixedly connected to the bracket 1, so that the first elastic member 4 is connected between the bracket 1 and the lifting seat 2. In this embodiment, the fixing seat 6 of the second elastic member 5 is detachably connected to the fixing seat 6' of the first elastic member 4 (for example, the fixing seat 6 has the protrusion 61, the fixing seat 6' is provided with a groove 61' matched with the protrusion 61, and the protrusion 61 and the groove 61' are detachably plugged along the second direction D2).

[0056] Further, in some possible embodiments, along the second direction, the fixing seat 6 preferably also has a hook (not shown), which is preferably arranged on the protrusion 61, and the fixing seat 6' also has a guide groove (not shown) adapted to the hook, which is preferably arranged in the groove 61'. When the protrusion on the fixing seat 6 and the groove on the fixing seat 6' are plugged in the second direction D2, the hook is clamped in the guide groove along the second direction D2, and the fixing seat 6 is limited by the hook and the groove, further preventing the fixing seat 6 from easily sliding away from the lifting seat 2 along the second direction D2, and the overall structural stability of the supporting device is better. Alternatively, it can be understood that the fixing seat 6 of the second elastic member 5 and the fixing seat 6' of the first elastic member 4 can be fixed integrally as needed, and the present invention is not limited thereto.

[0057] In addition, the first stretching end portion of the first elastic member 4 and the second stretching end portion 51 of the second elastic member 5 are located at the same side or different sides of the bracket 1 , but the present invention is not limited thereto.

[0058] Recombination Figure 3 , Figure 5-Figure 7 As shown, in one embodiment, the first connection structure includes a positioning block 52, which is fixedly connected to the second stretching end 51, and the positioning block 52 has a first end 52a and a second end 52b from top to bottom along the first direction D1.

[0059] The locking member 3 can be moved along the tangent direction of the surface of the stopper 31 (specifically Figure 5 or Figure 6 The locking member 3 is arranged on the bracket 1 for selectively being arranged in one of the first position and the second position, and the second connection structure of the locking member 3 is a stopper 31. When the locking member 3 moves to the first position, the stopper 31 moves into the moving path of the positioning block 52, and the stopper 31 stops the positioning block 52 in the first direction D1. When the locking member 3 moves to the second position, the stopper 31 moves out of the movable path of the positioning block 52. Specifically, when the positioning block 52 is located at the upper limit position of the movable path, (1) if the locking member 3 is moved to the first position along the ±X axis direction, the stopper 31 is relatively located directly below the first end 52a of the positioning block 52 to stop the positioning block 52 from moving downward. In this way, the positioning block 52 is locked to the bracket 1, that is, the second stretching end 51 of the second elastic member 5 is locked to the bracket 1, so that when the lifting seat 2 is adjusted in height, the first elastic member 4 and the second elastic member 5 are elastically deformed, and the first elastic member 4 and the second elastic member 5 jointly provide an elastic force for the lifting seat 2 to elastically support the bracket 1, so as to ensure that the lifting seat 2 can stably support objects with a heavier weight or objects with additional heavy accessories. (2) When the locking member 3 moves to the second position, the stopper 31 moves out of the movable path of the positioning block 52, and the stopper 31 is misaligned with the first end 52a of the positioning block 52, that is, the stopper 31 is relatively located below the first end 52a of the positioning block 52, so that the positioning block 52 can move downward, so that the positioning block 52 is separated from the bracket 1, and the positioning block 52 together with the lifting seat 2 can be lifted and lowered relative to the bracket 1 in the movable path, that is, the second elastic member 5 does not deform and moves with the lifting seat 2, and only the necessary elastic supporting force is provided by the first elastic member 4.

[0060] Furthermore, combined with Figure 5-Figure 7 As shown, in this embodiment, when the locking member 3 moves to the first position, the stopper 31 moves into the moving path of the positioning block 52, and the stopper 31 is located directly below the first end 52a and abuts against the first end 52a of the positioning block 52 to stop the positioning block 52 from moving downward in the first direction D1.

[0061] In addition, in a preferred embodiment, the bracket 1 further comprises a stopper 11, and in the first direction D1, the stopper 11 is located above the second end 52b of the positioning block 52 to stop the positioning block 52 from moving upward in the first direction D1 (e.g. Figures 5 and 6 As shown, the stopper 11 can stop the positioning block 52 from moving upward) and the stopper 11 has an escape space 11a, the escape space 11a is located below the stopper 31, when the locking member 3 moves to the second position, the escape space 11a can facilitate the passage of the first end 52a of the positioning block 52, and the positioning block 52 together with the lifting seat 2 can be lifted and moved relative to the bracket 1 in the movable path.

[0062] The locking member 3 moves to the first position, and the stop portion 11 of the bracket 1 cooperates with the locking member 3 to lock the positioning block 52: the stop portion 11 and the stop block 31 on the locking member 3 are both located between the first end 52a and the second end 52b of the positioning block 52, the stop portion 11 stops the positioning block 52 from moving upward, and the stop block 31 stops the positioning block 52 from descending, so that the positioning block 52 is limited and locked to the bracket 1, even if the second stretching end 51 of the second elastic member 5 is locked with the bracket 1. In this way, the stop portion 11 of the bracket 1 and the stop block 31 of the locking member 3 act together on the positioning block 52, ensuring that the positioning block 52 (and the second stretching end 51 of the second elastic member 5 connected thereto) are stably locked on the bracket 1. This double locking mechanism avoids accidental movement of the positioning block 52 and the second stretching end 51, thereby improving the stability and safety of the supporting device. At this time, when the lifting seat 2 is adjusted in height, the first elastic member 4 and the second elastic member 5 are elastically deformed, and the first elastic member 4 and the second elastic member 5 jointly provide an elastic force for the elastic support of the lifting seat 2 relative to the bracket 1.

[0063] When the locking member 3 moves to the second position, the stopper 31 separates from the positioning block 52, and the first end 52a of the positioning block 52 can pass through the avoidance space 11a on the stopper 11 of the bracket 1, so that the positioning block 52 and the lifting seat 2 can be lifted and lowered relative to the bracket 1 in the movable path. At this time, the second stretching end 51 separates from the bracket 1, the second elastic member 5 does not deform and moves with the lifting seat 2, and the stopper 11 limits the rising height of the positioning block 52 relative to the bracket 1. In this way, the locking and unlocking functions of the second stretching end 51 can be realized by moving the locking member 3.

[0064] Furthermore, combined with Figure 5 and Figure 7 As shown, the bracket 1 is provided with a limiting groove 12 , and the lifting seat 2 is provided with a protrusion 21 . Along the first direction D1 , the limiting groove 12 is located above the protrusion 21 to limit the rising height of the lifting seat 2 together with the fixing seat 6 relative to the bracket 1 .

[0065] Preferably, when the locking member 3 moves to the second position, the positioning block 52 is lifted and lowered along with the lifting seat 2. When the positioning block 52 is located at the upper limit position of the movable path, the second end 52b of the positioning block 52 rises and abuts against the stopper 11 of the bracket 1. At the same time, the lifting seat 2 and its protrusion 21 rise and move and abut against the limiting groove 12 of the bracket 1. In this way, when the locking member 3 moves to the second position, the lifting seat 2 and the second elastic member 5 are lifted and lowered at the same time and the lifting strokes are consistent. Only the first elastic member 4 provides necessary elastic support.

[0066] In another embodiment, if Figure 8a to Figure 8b As shown, the first connection structure includes a screw hole 53 extending along the second direction D2 on the positioning block 52. The locking member 3 is a screw arranged along the second direction D2, the screw is rotatably connected to the bracket 1, and the second connection structure is the threaded portion 32 of the screw. The locking member 3 is operated to rotate and move to the first position along the second direction D2 (i.e., the normal direction of the surface of the positioning block 52), and the threaded portion 32 is threadedly connected with the screw hole 53 to fix the second stretching end portion 51 of the second elastic member 5 with the bracket 1. At this time, when the lifting seat 2 moves relative to the bracket 1 along the first direction D1, the first elastic member 4 and the second elastic member 5 are deformed to provide the first elastic support and the second elastic support for the lifting seat 2 respectively; when the screw rod is operated to rotate in the opposite direction and move to the second position along the second direction D2, the threaded portion 32 of the screw rod is separated from the screw hole 53, so that the second elastic member 5 is separated from the bracket 1, and then only the first elastic member 4 provides the necessary elastic support; in this way, the screw rod is locked or separated from the screw hole on the positioning block 52, so that the switching of different elastic support modes can be realized, and then the elastic support force of the support device can be adjusted. In addition, or the above-mentioned first connection structure includes a through hole extending along the second direction D2 on the positioning block 52, and the above-mentioned locking member 3 is a pin shaft arranged along the second direction D2. The operation pin shaft is inserted or separated from the through hole on the positioning block 52, and switching of different elastic support methods can also be achieved. The present invention is not limited to this.

[0067] Refer to Figure 3 As shown, in one embodiment, the support device further comprises a friction block 7, which is disposed on the bracket 1 and has a friction surface 7S, and the friction surface 7S is in close contact with the outer surface of the lifting seat 2, so that a friction force can be generated between the lifting seat 2 and the bracket 1, and the friction force can be used as an auxiliary supporting force when the elastic force generated by the first elastic member 4 and / or the second elastic member 5 is insufficient to support the weight of the object, and can also be used as a compensating force when the weight of the object itself is insufficient to balance the elastic force generated by the first elastic member 4 and / or the second elastic member 5; in other words, the friction force has the effect of adjusting the supporting force that the support device can provide, so that the support device can be suitable for supporting objects with a wider weight range (such as display screens of various sizes).

[0068] In this embodiment, if Figure 3As shown, the supporting device further includes an adjusting member 71 and an elastic sheet 72. The adjusting member 71 is movably disposed on the bracket 1, and the elastic sheet 72 is held between the adjusting member 71 and the friction block 7. In this embodiment, the elastic sheet 72 is an arched elastic sheet structure, and the adjusting member 71 (such as a screw) can be rotated to control the elastic deformation of the elastic sheet 72, that is, to control the elastic force generated by the elastic sheet 72, which indirectly serves as a positive force for the friction surface 7S to contact the lifting seat 2.

[0069] In one embodiment, the supporting device of the present invention further comprises a lower sleeve 9 and an upper sleeve 8, such as Fig. 9 As shown ( Fig. 9 Schematic diagram of the overall structure of the support device of one embodiment). The lower sleeve 9 is sleeved on the bracket 1 and fixedly connected to the bracket 1, and the opening 91 provided therein allows at least part of the locking member 3 to be exposed, so as to facilitate the user to operate. The upper sleeve 8 is sleeved on the lower sleeve 9 and the lifting seat 2, and is fixedly connected to the lifting seat 2. The upper and lower sleeves 8 and 9 cooperate to form a protective shell structure, which enhances the overall stability of the support device while improving its aesthetics. In particular, when the object is a display screen, the upper sleeve 8 is also provided with a mounting interface 81 (such as a screw hole, a buckle, etc.) adapted to the display screen, so that the user can quickly and stably mount the display screen on the support device, thereby effectively simplifying the installation process. In addition, the present invention also provides a display device, including a display screen and the above-mentioned support device, the support device being used to support the display screen. However, the present invention is not limited thereto. For example, the bracket 1 and the lifting seat 2 of the support device of the present invention can be respectively connected to other connecting brackets to form a support device with more connecting brackets.

[0070] In summary, the support device provided by the present invention can realize the switching of different elastic support modes to adjust the elastic support force of the support device through a simple operation of the locking piece 3, can flexibly adapt to objects of different weights, meet the personalized needs of different users, and has a simple structure and convenient operation.

It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
