Detailed Description

Example 1

Refer to the figures throughout

The quick linkage retraction mechanism of the embodiment is arranged in a multi-section support arm assembly 2 with changeable height and angle, usually the head section of the support arm assembly 2 is fixed on the wall surface or the ground through a base body or a frame body, and the tail section of the support arm assembly 2 is provided with a display frame 5 through a part in the support arm assembly 2.

The quick linkage contraction mechanism comprises:

A wind power self-adaptive overturning actuating mechanism 3. The overturning executing mechanism 3 is one of core components of the contraction mechanism, and realizes the functions of installing and automatically overturning the display frame 5;

A linkage descent mechanism 4. When the wind force exceeds a threshold value, the wind force can rapidly trigger the supporting arm assembly to shrink, so that the display frame moves downwards to be close to the ground, and the wind load overturning moment arm is greatly reduced. The mechanism is matched with the turnover mechanism, so that the response capability to wind power is further enhanced, and the turnover mechanism is a key component for realizing rapid intelligent wind shrinkage resistance.

Through setting up simple reliable linkage decline module, with upset module cooperation, this embodiment has realized the quick location adjustment to the show frame, makes it keep stable under strong wind environment, avoids the upset. The double insurance design ensures the safety of the display equipment.

The support arm assembly 2 is formed by hinging a plurality of sections of rotating arms in series and comprises a first rotating arm 21, a second rotating arm 22 and a third rotating arm 23. Wherein the tilting actuator 3 is arranged in the third swivel arm 23. For clarity of description of the tilting mechanism, the present embodiment establishes a coordinate system for explanation.

1. A display frame mount 31 mounted on the third rotary arm 23 to rotate only about the Z axis;

2. The elastic telescopic piece 32 with a U-shaped groove at one end, wherein the other end of the elastic telescopic piece 32 is provided with a transition surface 321 which can slide along the X axis relative to the third rotating arm 23, and the U-shaped groove is in sliding fit with a corresponding guide groove in the third rotating arm 23 to form a parallel guide groove 06;

3. a hinge shaft 33, the middle part of which is arranged in the parallel guide groove 06, the two ends of which are exposed and hinged with the display frame mounting seat 31, and the hinge shaft 33 can slide in the X-axis direction;

4. one end of the limiting connecting rod 34 is slidably/lockably connected with the parallel guide groove 06 through the sliding seat 07, and the other end is hinged with the display frame mounting seat 31, and the limiting connecting rod limits the rotation of the display frame mounting seat 31 in the display state and the contracted state.

The mechanism realizes the directional rotation of the mounting seat 31 through the hinge shaft 33, the limit connecting rod 34 and the parallel guide groove 06. The upward overturning is used for showing the state, and the downward overturning is limited, so that collision with other parts is avoided. The simple mechanism realizes controllable overturning of the display frame. The function of the limit link 34 is to pull or support the display frame 5 so that the hinged mounting shaft 33 is maintained in two stable positions, and the limit link 34 is positioned so that the display frame 5 can only be flipped up. This is because when the display frame 5 is turned down, the hinge mounting shaft 33 is required to move distally within the parallel guide channels 06, with the distal end being restrained by the closed end of the channel. This design is because the space for the display frame 5 to be turned down is limited by other parts such as the second swivel arm, and both collide with each other, thus not allowing the turning down.

The key of the overturning executing mechanism for realizing wind power self-adaptive overturning is matched assembly of all components. In assembly, the elastic extension 32 is first fully extended and the sliding seat 07 is adjusted so that the hinge mounting shaft 33 is located at the distal end of the guide slot 06, leaving a small gap between the transition surface 321 and the display frame mounting seat 31.

In this way, under normal circumstances, the rotation shaft 33 is kept at the distal end position under the elastic force of the elastic telescopic member 32, and the display frame mounting seat 31 is in the upright display state. When the environmental wind force increases, the wind force action overcomes the elasticity and pushes the elastic telescopic piece 32 to shrink, the rotating shaft 33 moves in the guide groove, and the mounting seat 31 is driven to rotate and turn over to shrink and fold.

Through the cooperation of elastic expansion piece and slewing mechanism, realized response and mechanical response to environment wind-force, make the show frame realize automatic upset shrink. The simple mechanism has compact structure and reliable movement, and is the core of the embodiment.

The action principle of the overturning executing mechanism is as follows:

Under normal conditions, the elastic telescopic member 32 is in an extended state, so that the rotating shaft 33 is fixed at the distal end, and the display frame is in an upright display position. When the wind force increases, the torque compresses the spring 04 and pushes the elastic expansion member 32 to contract, and the rotation shaft 33 moves accordingly. Along with the increase of wind force, the compression amount is accumulated to a critical value, and the return force when the spring is released drives the rotating shaft and the mounting seat to rotate and overturn rapidly, so that the display frame is folded to be in a horizontal state. At this time, the limit connecting rod 34 enters the upper edge of the conversion surface 321, so that complete separation is prevented, and wind load is greatly reduced.

The mechanism realizes wind force induction and mechanical response through the cooperation of spring retention and quick release overturning, so that the display frame can be folded and contracted stably and reliably. The design of the conversion surface is beneficial to smooth reset action. The succinct mechanism is a key for realizing intelligent wind shrinkage resistance.

The linkage descending mechanism 4 adopts a mechanical linkage mode to realize quick descending positioning of the display frame 5. It comprises a flexible elastic linkage belt 41 which is arranged around the hinge of the second rotating arm 22 and the third rotating arm 23, one end of the linkage belt 41 is connected with the turnover mechanism 3 through an extending connecting part 43, and the other end is fixed on the third rotating arm 23. A stop block 44 and a corresponding stop shaft 45 are also provided below the linkage belt 41. The linkage descending mechanism 4 has a more specific structure and also comprises a notch 42, an extending connecting part 43, a stop block 44, a spring piece 442, a stop block 44 and a stop block 44, wherein the notch 42 is arranged at the hinge joint of the second rotating arm 22 and the third rotating arm 23 and is used for the linkage belt 41 to pass through, the extending connecting part 43 is positioned at one side of the hinge mounting shaft 33 facing the rotating arm and is used for connecting the linkage belt 41, one end of the linkage belt 41 is fixed on the third rotating arm 23, the other end of the linkage belt 41 passes through the notch 42 and is connected with the extending connecting part 43, the stop block 44 is in an inverted cone shape, the bottom is provided with a pressing engagement tooth 441, the middle section is provided with a spring piece 442 extending outwards, and the spring piece 442 enables the stop block 44 to spring up towards the distal end and enables the stop block 44 to be restrained in a certain movable space. The stopper 44 is located below the link belt 41, a stopper rotating shaft 45 fixed to the third rotating arm 23 and provided on its outer periphery with surrounding engagement teeth 451 engaged with the pressing engagement teeth 441, and a stopper mounting portion 46 provided on the second rotating arm 22 and having a mounting portion of a spring piece 442 in a shape matching the outer shape of the stopper 44. Which corresponds in position to encircling the engagement teeth 451.

When the display frame 5 is in the vertical display state, referring to fig. 1-2, the link belt 41 is in a stretched state, and at this time, the engagement teeth 441 of the stopper 44 engage with the surrounding engagement teeth 451, so that the third rotating arm 23 is in a locked stable state.

When the display frame 5 is turned to a horizontal state by wind force, the hinge mounting shaft 33 moves to the rotating arm side, and the extension connecting part 43 is driven to move synchronously, so that the linkage belt 41 is loosened from the original tightening state. At this time, the stopper 44 is disengaged from the engaged state with the surrounding engagement teeth 451 by the spring piece 442, and the third rotation arm 23 is also changed from the locked state to the rotatable state.

The third arm 23 is rapidly rotated down around the hinge under its own weight. This downward rotation again tightens the slack strap 41 against the hinge. Finally, the display frame 5 is moved down to the low steady state, and the third swivel arm 23 is again locked.

In this way, the display frame 5 is quickly lowered from the high-level state to the low-level vertical state, and still can continue to display, while avoiding overturning.

To avoid the spring plate 442 being easily separated after multiple uses, the middle section of the stopper 44 may be intermittently separated into two parts, i.e. the spring plate 442 and the stopper body are separated. The two are connected by a hinge or other connection mode. Thus, when the spring plate 442 is elastically deformed, the whole stopper 44 is not displaced, thereby ensuring the normal function of the spring plate 442.

Further, as for the spring pieces 442, a plurality of spring pieces may be provided in a distributed manner, that is, a plurality of spring pieces may be provided at different positions in the circumferential direction of the stopper 44. This may allow for better balance and stability of the stop block 44. The elastic force of each spring piece can be optimized and balanced through design.

The shrinkage method of the quick linkage shrinkage mechanism comprises the following steps:

1. under normal conditions, the elastic telescopic member 32 is in an extended state, so that the rotating shaft 33 is fixed at the distal end, and the display frame is in an upright display position.

2. When the wind force increases, the wind force compresses the spring 04 and pushes the elastic expansion member 32 to contract, and the rotating shaft 33 moves in the parallel guide grooves 06.

3. When the wind force increases to a critical value, the spring will release the return force to drive the rotating shaft 33 and the mounting seat 31 to rotate and turn over, and the display frame is folded to be in a horizontal state.

4. The display frame is turned to a horizontal state, and the interlocking belt 41 is changed from the original tensed state to the loose state.

5. The stopper 44 is disengaged from the surrounding engagement teeth 451 by the spring piece 442, and the third rotary arm 23 becomes rotatable.

6. The third arm 23 is rapidly rotated down around the hinge under its own weight to complete the descent while tightening the loose link belt 41 again.

7. The display frame is moved down to the low steady state and the third swivel arm 23 is again locked.

8. Finally, the display frame is quickly lowered from a high-level state to a low-level vertical state, and quick shrinkage is realized.

Example 2:

application of quick linkage contraction mechanism in outdoor LED display screen

The quick linkage shrinkage mechanism of the embodiment is applied to wind resistance protection of an outdoor LED display screen.

The display screen main body is arranged on a plurality of sections of supporting arms with adjustable angles, and the tail ends of the supporting arms are connected with the display screen through a quick linkage contraction mechanism. The structure of the contraction mechanism is basically the same as that of the embodiment 1, and mainly comprises a wind power self-adaptive overturning executing mechanism and a linkage descending mechanism.

When the display screen works normally, the support arm lifts the display screen to a high position, and the wind power self-adaptive overturning executing mechanism keeps the display screen in an upright state. When the wind power is increased, the display screen can be turned to a horizontal folding state under the action of the wind power, and meanwhile, the linkage belt drives the support arm to rapidly descend so as to move the display screen downwards to the vicinity of the ground.

Therefore, the display screen can avoid overturning and damaging under the strong wind condition, and the wind load overturning moment is greatly reduced when the height is quickly lowered, so that the safety of the equipment is ensured. Meanwhile, advertisement or prompt information can be continuously played in the folding state, so that the continuity of the service is ensured.

According to the embodiment, the intelligent wind-resistant protection of the display screen is realized through simple mechanical dynamics design, so that the device can adapt to wider use environments, and the market applicability of products is improved.

The quick linkage shrinkage mechanism is applied to a photovoltaic support system for solar power generation, and realizes quick shrinkage and turnover of a hinged solar panel.

The solar panel is lifted and installed through the hinge type supporting arm, and the supporting arm can rotate around the horizontal shaft by +/-60 degrees, so that tracking of the position of the sun is realized, and higher power generation efficiency is obtained.

Under the action of the wind power self-adaptive overturning executing mechanism, the solar panel translates and overturns to a folding state parallel to the ground, and meanwhile, the linkage belt drives the supporting arm to rapidly rotate downwards so as to enable the solar panel to be close to the ground.

Therefore, the solar panel is prevented from being overturned and damaged or blown off in the strong wind, meanwhile, the wind load overturning moment is greatly reduced, and the safety of equipment is ensured. After the wind force is weakened, the solar panel can be automatically reset to a working state.

The embodiment increases the adaptability to severe weather for the solar tracking system, so that the solar tracking system can be applied to places with more severe environmental conditions, and the practicability of the device is improved. And meanwhile, the safety and the reliability of the system are enhanced.

Example 4 quick collapse of folding shed

The shrinkage mechanism can be applied to a folding carport to realize rapid folding and storage of the carport.

Roof cover of bicycle shed passes through multiple sections the hinge bracket is connected with the ground. Under normal condition, the support is used with the top cap elevation. When strong wind is encountered, the wind power self-adaptive turnover mechanism drives the top cover to turn over to a vertical storage state, and meanwhile, the linkage mechanism drives the bracket to quickly retract downwards to store the top cover close to the ground.

Therefore, the shed can be prevented from being overturned and damaged when being blown by strong wind, and the structural safety is ensured. And realizes the rapid storage of the carport.

Example 5 quick storage of folding vans

The folding mechanism is applied to a folding caravan, and can be used for rapidly storing tarpaulin.

The roof tarpaulin is arranged on the roof through a plurality of sections of movable frameworks. Under the normal state, the framework lifts the tarpaulin for use. When strong wind is encountered, the turnover mechanism drives the tarpaulin to fold, and the linkage mechanism drives the framework to rapidly rotate downwards to collect the tarpaulin into the vehicle.

Therefore, the tarpaulin is prevented from being blown out under the attack of strong wind, and the safety of the vehicle is ensured. And realize the quick intelligent storage to tarpaulin.
