As shown in fig. 8, the bearing seat 406 includes a bearing connecting rod 4062 and a bearing seat body 4061, one end of the bearing connecting rod 4062 is hinged to the second bearing seat bracket 407, and the bearing seat body 4061 is movably mounted (e.g. inserted) to the other end of the bearing connecting rod 4062 and can slide along the length direction of the bearing connecting rod 4062 to adjust the relative position of the bearing seat body 4061 and the bearing connecting rod 4062. Of course, the bearing seat body 4061 may also be fixedly connected to the other end of the bearing link 4062.
As shown in fig. 8, the holding mechanism 408 includes a third link 4081, a fourth link 4081, and a fifth linear actuator 4083, wherein one end of the third link 4081 is hinged to the middle portion of the carrier, the other end of the third link 4081 is hinged to one end of the fourth link 4081, one end of the fifth linear actuator 4083 is hinged to the carrier support, and the other end of the fifth linear actuator 4083 is hinged to the fourth link 4081 or the middle portion of the third link 4081. In order to avoid interference between the fifth linear actuator 4083 and other components of the holding mechanism 408 during operation, the fifth linear actuator 4083 is disposed on one side of the holding mechanism 408.
It will be appreciated that in some embodiments, the ganged-type displacement apparatus may also be provided without the carriage mechanism 40 as shown in fig. 9. The combined type bearing mechanism 30 can be used independently together with the armrest 3094, so that a user can be helped to complete a standing process, and a certain walking assisting and weight reducing effect is achieved for the user in a short time.
In summary, according to the linkage type bearing mechanism of the linkage type shifting device, through the cooperation of the parallelogram lifting mechanism, the gear transmission part and the crank sliding block mechanism, the sliding part of the crank sliding block mechanism can do linear reciprocating motion along the approximately horizontal direction while the height adjustment is realized through the parallelogram lifting mechanism, so that the curve motion similar to the movement of a person in a sitting position and a standing position is realized, and the action process of the person from the standing position to the sitting position is simulated. The linkage type shifting device can be used by a user to simply finish operation through the armpit support, the elbow support or/and the suspension/binding component, and reduce the operation of a caretaker. The linkage type shifting device can realize the cooperation of the linkage type bearing mechanism and the open-close type bearing seat mechanism. The length of the support frame can be set to be adjustable under the condition of ensuring that the rotation amplitude of the parallelogram lifting mechanism is certain aiming at the crowd with different heights, and the linkage type shifting device is suitable for the crowd with larger heights and more occasions. The linkage type shifting device can realize the shifting function, can provide the walking aid and the weight reduction function in a short time, and can realize the shifting simply and quickly by a user.
