Description

Technical Field

[0001] This utility model relates to the field of console equipment technology, and in particular to a lifting mechanism and a movable console. Background Technology

[0002] In the field of control consoles (emergency dispatch centers, emergency command, simulated command and control, etc.), control console equipment often needs to quickly adapt to different scenario requirements and is therefore required to have rapid deployment capabilities. Traditional fixed control consoles have poor mobility. To improve mobile deployment capabilities, a mobile control console has emerged in the prior art. This mobile control console has multiple wheels equipped with braking modules installed at its bottom. When the control console needs to be moved and deployed, the braking modules are released, allowing the control console to move using the wheels. After deployment, the braking modules are switched back to the locked state to restrict the movement of the wheels. Thus, this mobile control console can achieve strong mobile deployment capabilities. However, this type of mobile control console has the following drawbacks:

[0003] When the console is in use (and the console is in use for a long time), the entire weight of the console is borne by the wheels, which will inevitably affect the service life of the wheels. In addition, locking the wheels by the braking module cannot guarantee that the console is in a good stable state, that is, the stability of the console is poor. Utility Model Content

[0004] In view of the above-mentioned technical problems existing in the prior art, the present invention provides a lifting mechanism and a movable control console.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

The lifting component includes: a top component, at least one bottom component located below the top component, a traveling wheel mounted on the bottom component, and a plurality of rocker components located between the top component and the bottom component and pivotally connected to the top component and the bottom component to form a four-bar linkage. The force-applying component is used to drive the rocker components to twist.

[0011] Preferably, the force-applying component includes a force-applying rod, which is fixedly connected to the rocker component of the four-bar linkage to which the active rocker belongs.

[0012] Preferably, the force-applying component further includes an electrostrictive component, one end of which is pivotally connected to the top component, and the other end of which is pivotally connected to the bottom component corresponding to the active rocker arm.

[0013] Preferably, a mounting base is provided on the top component, the mounting base is slidably engaged with the top component and can be fixed to the top component; the end of the electrostrictive component is pivotally connected to the mounting base.

[0014] Preferably, the lifting mechanism includes two lifting components; the force-applying component is arranged on one of the lifting components; wherein:

[0015] A drive shaft is provided between the opposing rocker components belonging to the two lifting components so that the rocker components belonging to the two lifting components rotate synchronously.

[0016] Preferably, the end of the drive shaft is connected to the pivot point of the rocker arm component.

[0017] Preferably, the top of the top component is configured with a mating plane for mating with the bottom of the console body, and the bottom of the console body is provided with baffles in the front and rear directions, and the baffles are provided with braking surfaces for stopping the top component.

[0034] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0035] like Figure 1 As shown, an embodiment of the present invention discloses a lifting mechanism 100 and a movable control console having the lifting mechanism 100, wherein the lifting mechanism 100 is arranged at the bottom of the control console body 200 of the movable control console.

[0036] like Figures 2 to 6 As shown, the lifting mechanism 100 includes two lifting components 10 and a force-applying component for directly driving one of the lifting components 10. The two lifting components 10 are arranged on both sides of the bottom of the console body 200 in the width direction. Each lifting component 10 includes a top component 11, two bottom components 12, multiple rocker components, and multiple wheels 15.

[0037] The top component 11 is configured as a strip structure with a flat mating surface on the top. The top component 11 is arranged along the front and rear direction of the console body 200. The inner and outer sides of the top component 11 have two opposing side plates for pivoting the rocker arm component. The two bottom components 12 are located below the top component 11 and are arranged along the front and rear direction of the console body 200. Each bottom component 12 also has two side plates for pivoting the rocker arm component and for mounting the wheels 15. A wheel 15 is mounted between the two side plates of each bottom component 12.

[0038] Four rocker components are pivotally connected between the bottom component 12 and the top component 11 on the front side, and four rocker components are pivotally connected between the bottom component 12 and the top component 11 on the rear side. The four rocker components on the front side are divided into two groups, front and rear, and pivotally connected between the bottom component 12 and the top component 11 on the front side. Each group of rocker components is located on both sides of the bottom component 12 and the top component 11 on the front side and is coaxially pivotally connected to their side plates, thus forming a four-bar linkage on the front side. The four rocker components on the front side can be named according to their positions as: the first front outer rocker 132, the first rear outer rocker 133, the first rear outer rocker 134, the first rear outer rocker 135, the first rear outer rocker 136, the first rear outer rocker 137, the first rear outer rocker 138, the first rear outer rocker 139 ... The four rocker components on the rear side are also divided into two groups, front and rear, and pivotally connected between the bottom component 12 and the top component 11 on the rear side. Each group of rocker components is located on both sides of the bottom component 12 and the top component 11 on the rear side and is coaxially pivotally connected to its side plate, thus forming a four-bar linkage mechanism on the rear side. The four rocker components on the rear side can be named according to their positions as: second front outer rocker 142, second rear outer rocker 141, second front inner rocker 144, and second rear inner rocker 143.

[0039] Since the bottom component 12 and the top component 11 form a four-bar linkage via rocker components, the bottom component 12 and the top component 11 can move closer to or further apart by driving one of the rocker components in the four-bar linkage to twist. Thus, as... Figure 5 As shown, when the bottom component 12 and the top component 11 are moved away from each other, the lifting component 10 supports the ground via the wheels 15 on the bottom component 12, and lifts the console body 200 via the top component 11, thereby raising the bottom legs of the console body 200 off the ground. This allows it to move using the wheels 15 to meet deployment requirements. Figure 4 As shown, when the bottom component 12 and the top component 11 are brought close to each other, the console body 200 falls back, and then the bottom support of the console body 200 supports the ground again, so as to eliminate the need to use the wheels 15 for support. Thus, the console body 200 avoids the need to use the wheels 15 for support when it is in use, thereby improving the service life of the wheels 15 and the stability of the console body 200 in use.

[0040] Preferably, the rocker arm component after lifting is not perpendicular to the ground; that is, during lifting, the rocker arm component is perpendicular to the ground and then deflects at a certain angle. Therefore, the distance between the bottom component 12 and the top component 11 increases to its maximum and then decreases slightly. Preferably, the lifting component 10 can be kept in the lifted state by installing a stop post on the top component 11 to limit the torsion of the rocker arm component. Preferably, the lifting component 10 can be kept in the lifted state by providing baffles in the front and rear directions at the bottom of the control console body 200, with the inner surface of the baffles acting as a braking surface to stop the end of the top component 11 and limit excessive displacement of the top component.

[0041] like Figure 2 As shown, a transmission rod 16 connects the front four-bar linkage and the rear four-bar linkage. The transmission rod 16 is used to link the two four-bar linkages, so that the two bottom parts 12 move closer to or further away from the bottom parts 12 synchronously, thereby improving the stability of lifting or lowering one side of the console body 200.

[0042] The force-applying components include a force-applying rod 21 and an electro-telescopic rod 22, which can be installed on the same lifting component 10.

[0043] The force-applying lever 21 is fixed to the first front outer rocker arm 132 and forms a certain angle with the first front outer rocker arm 132. Preferably, the force-applying lever 21 is integrally formed with the first front outer rocker arm 132. Thus, by manually pressing down the force-applying lever 21, the first front outer rocker arm 132 of the front four-bar linkage can be driven to twist, and the remaining rocker arm components can be twisted through the transmission rod 16, thereby causing all the rocker arm components of the rear four-bar linkage to twist, so that the two bottom components 12 and the top component 11 are moved away from each other, thereby raising the console body 200. By manually lifting the force-applying lever 21, the first front outer rocker arm 132 of the front four-bar linkage can be driven to twist in the opposite direction, and the remaining rocker arm components can be twisted in the opposite direction through the transmission rod 16, thereby causing the console body 200 to fall back down.

[0044] An electro-telescopic rod 22 is obliquely arranged between the top component 11 and the front bottom component 12. Both ends of the electro-telescopic rod 22 are pivotally connected to the top component 11 and the front bottom component 12, respectively. The electro-telescopic rod 22 extends to drive the front bottom component 12, causing the bottom component 12 to eventually move away from the top component 11, thereby raising the console body 200. Conversely, it retracts to drive the front bottom component 12, causing the bottom component 12 to eventually move closer to the top component 11, thereby lowering the console body 200. In some preferred configurations, such as... Figure 3As shown, a guide groove is provided on the top of the top component 11, and a mounting seat 23 is installed on the guide groove so that the mounting seat 23 can slide along the guide groove. The top of the mounting seat 23 is located above the mating surface of the top component 11, and the bottom of the mounting seat 23 is located below the mating surface. The end of the electro-telescopic rod 22 is pivotally connected to the bottom of the mounting seat 23. When the electro-telescopic rod 22 is used to drive the console body 200 to lift and lower, the bottom of the mounting seat 23 is fixed to the top component 11 by fasteners, so that the electro-telescopic rod 22 can drive the bottom component 12. When the force rod 21 is used to drive the console body 200 to lift and lower, the fasteners are removed so that the mounting seat 23 can slide along the guide groove. In this way, when the force rod 21 drives the rocker component and causes the bottom component 12 to move, the electro-telescopic rod 22 can follow the movement of the bottom component 12 with the help of the sliding of the mounting seat 23 without interfering with the movement of the bottom component 12.

[0045] like Figure 6 As shown, the two lifting components 10 rotate synchronously via a drive shaft 30. Specifically, both ends of the drive shaft 30 are connected to the pivot points of the first front inner rocker arm 134 and the top component 11 of the four-bar linkage on the front side of the two lifting components 10, respectively, so that the drive shaft 30 and the first front inner rocker arm 134 are connected in a synchronous rotation manner. For example, synchronous torsion can be achieved by configuring a flat column at the end of the drive shaft 30 and engaging with a flat hole opened in the rocker arm component. Thus, when the force-applying component causes one lifting component 10 to move, the other lifting component 10 moves synchronously, thereby lifting and lowering the control console body 200 on both sides in the width direction.

[0046] This utility model provides a preferred connection method between the transmission rod 16 and two four-bar linkages. Specifically, the first rear outer rocker 131 of each lifting component 10 serves as the active rocker, and the second front outer rocker 142 serves as the driven rocker. The end of the second front outer rocker 142, which is pivotally connected to the top component 11, extends upward (and can extend at an angle) to form an extension 1421. The two ends of the transmission rod 16 are respectively pivotally connected to the pivot point between the first rear outer rocker 131 and the front bottom component 12, and to the end of the extension 1421. Thus, when the two four-bar linkages are activated to enable or retract the control console body 200, The four-bar linkage on the front side and the four-bar linkage on the rear side are always in a symmetrical state. Therefore, during the operation, the bottom component 12 on the front side and the bottom component 12 on the rear side generate relative or opposite movements in the horizontal direction. This causes the friction between the walking wheels 15 installed on the two bottom components 12 and the ground (the direction of the friction is the front-back direction of the console body 200) to cancel each other out. This avoids the console body 200 from moving back and forth when the console body 200 is raised or lowered, because the bottom component 12 has front and back horizontal movement components and the friction cannot be canceled out.

[0047] The lifting mechanism 100 and the movable control console provided by this utility model have at least the following advantages:

[0048] 1. By configuring a lifting mechanism 100 at the bottom of the console body 200, the console body 200 can be lifted by the lifting mechanism 100 to achieve mobile deployment with the help of the wheels 15, and the console body 200 can be lowered by the lifting mechanism 100 to avoid using the wheels 15 for support, thereby improving the stability of the console body 200 when it is in use.

[0049] 2. The control console body 200 can be raised and lowered by manually driving the force bar 21 or by electrically driving the electro-hydraulic telescopic bar 22, and the operation can be switched between manual and electric.

[0050] 3. This movable console can be moved quickly, allowing the console layout to be changed rapidly.

[0051] 4. The ingenious connection between the transmission rod 16 and the two four-bar linkages suppresses the horizontal movement of the console body 200 during lifting or lowering.
