[0035] In order to keep the following description of the embodiments of the present application clear and concise, detailed description of known functions and known components is omitted from the present application.
[0036] As shown in Figure 1 An embodiment of the present application discloses a lifting mechanism 100 and a movable console having the same, the lifting mechanism 100 being arranged at the bottom of a console body 200 of the movable console.
[0037] As shown in Figures 2 to 6 The lifting mechanism 100 includes two lifting members 10 and a force applying member for directly driving one of the two lifting members 10. The two lifting members 10 are arranged at both sides in the width direction of the bottom of the console body 200, each of the two lifting members 10 including a top member 11, two bottom members 12, a plurality of rocker members, and a plurality of traveling wheels 15.
[0038] The top part 11 is configured as a strip structure with a flat joint surface on the top, and is arranged along the front-rear direction of the console body 200. The inner and outer sides of the top part 11 have two opposite side plates for pivoting the rocker parts. Two bottom parts 12 are arranged below the top part 11 along the front-rear direction of the console body 200. Each bottom part 12 also has two side plates for pivoting the rocker parts and mounting the walking wheels 15. The walking wheels 15 are mounted between the two side plates of each bottom part 12.
[0039] Four rocker parts are pivoted between the front bottom part 12 and the top part 11, and four rocker parts are pivoted between the rear bottom part 12 and the top part 11. The four rocker parts on the front side are divided into two groups and pivoted between the front bottom part 12 and the top part 11. Each group of rocker parts is located on the two sides of the front bottom part 12 and the top part 11 and is coaxially pivoted to the side plates, thereby forming a four-bar mechanism on the front side. The four rocker parts on the front side are named as first front outer rocker 132, first rear outer rocker 131, first front inner rocker 134, and first rear inner rocker 133 based on their positions. The four rocker parts on the rear side are also divided into two groups and pivoted between the rear bottom part 12 and the top part 11. Each group of rocker parts is located on the two sides of the rear bottom part 12 and the top part 11 and is coaxially pivoted to the side plates, thereby forming a four-bar mechanism on the rear side. The four rocker parts on the rear side are named as second front outer rocker 142, second rear outer rocker 141, second front inner rocker 144, and second rear inner rocker 143 based on their positions.
[0040] Since the bottom part 12 and the top part 11 form a four-bar mechanism through the rocker parts, the bottom part 12 and the top part 11 can approach or move away from each other by driving one of the rocker parts in the four-bar mechanism to twist. Thus, as shown in FIG. 6, when the bottom part 12 and the top part 11 move away from each other, the lifting part 10 is supported by the walking wheels 15 on the bottom part 12 to support the ground, and the console body 200 is lifted by the top part 11, so that the feet at the bottom of the console body 200 are lifted off the ground. Thus, the console body 200 can be moved by the walking wheels 15 to meet the deployment requirements, as shown in FIG. 7. Figure 5 Figure 4 When the bottom part 12 and the top part 11 approach each other, the console body 200 falls back, and then the feet at the bottom of the console body 200 support the ground again to eliminate the support by the walking wheels 15, so that the console body 200 avoids being supported by the walking wheels 15 when in use, improving the service life of the walking wheels 15 and the stability of the console body 200 in use.
[0041] Preferably, the lever member after lifting is not made to be perpendicular to the ground, that is, during lifting, the lever member is deflected after being perpendicular to the ground by a certain angle, thus the distance between the bottom member 12 and the top member 11 is increased to the maximum and then decreased. Preferably, the lifting member 10 can be kept in the lifting state by installing a stopper column on the top member 11 to limit the torsion of the lever member. Preferably, the bottom of the console body 200 can be kept in the lifting state by installing a baffle in the front and rear directions of the bottom of the console body 200, and the inner side surface of the baffle can be used as a braking surface to stop the end of the top member 11 to limit the excessive displacement of the top member, thus the lifting member 10 can be kept in the lifting state.
[0042] As shown in Figure 2 The transmission rod 16 is connected between the front four-bar linkage and the rear four-bar linkage, and is used to link the front and rear four-bar linkages, thus the two bottom members 12 are synchronized to approach or move away from the bottom member 12, thus the stability of lifting or falling of one side of the console body 200 can be improved.
[0043] The force applying member includes a force applying rod 21 and an electrostrictive rod 22, and the force applying rod 21 and the electrostrictive rod 22 can be installed on the same lifting member 10.
[0044] The force applying rod 21 is fixed on the first front outer rocker 132 and is at a certain angle with the first front outer rocker 132, and preferably, the force applying rod 21 is integrally formed with the first front outer rocker 132. Thus, the first front outer rocker 132 of the front four-bar linkage and the rest of the lever members can be driven to twist by manually pressing down the force applying rod 21, and all the lever members of the rear four-bar linkage can be driven to twist by the transmission rod 16, thus the two bottom members 12 are moved away from the top member 11, and the console body 200 is lifted. The first front outer rocker 132 of the front four-bar linkage and the rest of the lever members can be driven to reverse twist by manually lifting up the force applying rod 21, and all the lever members of the rear four-bar linkage can be driven to reverse twist by the transmission rod 16, thus the console body 200 is fallen.
[0045] The electrostrictive rod 22 is obliquely arranged between the top member 11 and the front bottom member 12, and the two ends of the electrostrictive rod 22 are respectively pivoted to the top member 11 and the front bottom member 12. The front bottom member 12 is driven to move away from the top member 11 by the elongation of the electrostrictive rod 22, thus the console body 200 is lifted, and the front bottom member 12 is driven to move close to the top member 11 by the retraction of the electrostrictive rod 22, thus the console body 200 is fallen. In some preferred structures, as shown in Figure 3As shown, a guide slot is opened on the top of the top part 11, and a mounting seat 23 is arranged on the guide slot so that the mounting seat 23 can slide along the guide slot, the top of the mounting seat 23 is above the joint surface of the top part 11, the bottom of the mounting seat 23 is below the joint surface, and the end of the electrostrictive rod 22 is pivoted to the bottom of the mounting seat 23, when it is needed to drive the console body 200 to lift and fall by the electrostrictive rod 22, the bottom of the mounting seat 23 is fixed to the top part 11 by fasteners, so that the electrostrictive rod 22 can drive the bottom part 12, and when the console body 200 is driven to lift and fall by the force applying rod 21, the fasteners are removed so that the mounting seat 23 can slide along the guide slot, thus, when the bottom part 12 is moved by the driving of the rocker part by the force applying rod 21, the electrostrictive rod 22 can comply with the movement of the bottom part 12 by the sliding of the mounting seat 23 without interfering with the movement of the bottom part 12.
[0046] As shown, Figure 6 As shown, the two lifting parts 10 are synchronously rotated by a transmission shaft 30, specifically, the two ends of the transmission shaft 30 are respectively connected with the first front inner rocker 134 of the four-bar linkage mechanism of the front side of the two lifting parts 10 and the pivoting point of the top part 11, and the transmission shaft 30 is connected with the first front inner rocker 134 in a synchronous rotating manner, for example, the synchronous torsion can be realized by configuring a flat column on the end of the transmission shaft 30 and matching with the flat hole opened on the rocker part. Thus, when the force applying part drives one of the lifting parts 10 to act, the other lifting part 10 acts synchronously, so that the console body 200 is lifted and falls on both sides in the width direction.
[0047] The application provides a preferred connection mode of a transmission rod 16 and two four-bar linkages, specifically, the first rear outer rocker 131 of each lifting component 10 is used as a driving rocker, the second front outer rocker 142 is used as a driven rocker, the end of the second front outer rocker 142, which is pivotally connected to the top component 11, extends upward (can extend obliquely) to form an extension 1421, and the two ends of the transmission rod 16 are respectively pivotally connected to the pivot connection points of the first rear outer rocker 131 and the front bottom component 12 and the end of the extension 1421, so that when the two four-bar linkages are actuated to realize the lifting or retraction of the console body 200, the front four-bar linkage and the rear four-bar linkage are always in a symmetrical state, and thus, during the actuation, the front bottom component 12 and the rear bottom component 12 produce relative movement or opposite movement in the horizontal direction, which makes the friction between the walking wheels 15 respectively installed on the two bottom components 12 and the ground (the direction of the friction is the front-rear direction of the console body 200) offset each other, thereby avoiding the front-rear movement of the console body 200 caused by the horizontal movement of the bottom components 12 and the unbalanced friction when the console body 200 is lifted or retracted.
[0048] The lifting mechanism 100 and the movable console provided by the application have at least the following advantages:
[0049] 1. The lifting mechanism 100 is arranged at the bottom of the console body 200, so that the console body 200 can be lifted by the lifting mechanism 100 to realize the movement and deployment by the walking wheels 15, and the console body 200 can be retracted by the lifting mechanism 100 to avoid being supported by the walking wheels 15, thereby improving the stability of the console body 200 in the use state.
[0050] 2. The lifting and retraction of the console body 200 can be realized by manually driving the force applying rod 21 or by electrically driving the electrostrictive rod 22, and the manual and electric modes can be switched.
[0051] 3. The movable console can move quickly, so that the console can be quickly changed in layout.
[0052] 4. The ingenious connection mode of the transmission rod 16 and the two four-bar linkages can inhibit the horizontal movement of the console body 200 during the lifting or retraction.
