[0023] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0024] Reference Figs. 1 to 4 According to a preferred embodiment of the utility model, the elevator with a buffer member to be described in detail below is arranged in the sliding space 901 of the elevator shaft 90. The elevator with a buffer member comprises a car member 10, a driving assembly 20 and at least one buffer member 30.

[0025] The car member 10 comprises a car 11 and a car rail 12, wherein the car rail 12 is vertically fixed to the inner wall of the sliding space 901 formed by the elevator shaft 90, the car 11 is slidably mounted on the car rail 12, and the car 11 is connected to the driving assembly 20 in a drivable manner for lifting.

[0026] The buffer member 30 is mounted at the bottom of the sliding space 901 of the elevator shaft 90, and the buffer member 30 comprises at least two buffer bodies 31 and a buffer duct 32, wherein the two buffer bodies 31 are stacked together, and each buffer body 31 can be compressed and restored after compression. Each buffer body 31 forms a compression space 3101 inside, and the compression space 3101 is used to accommodate fluid. The bottom outer wall of each buffer body 31 forms a communication groove 3102, and at least one end of the communication groove 3102 extends to the side wall. Each buffer body 31 also forms a communication hole 3103, and the communication hole 3103 communicates the compression space 3101 and the communication groove 3102.

[0027] One end of the buffer duct 32 is arranged along the communication groove 3102 and connected to one of the buffer bodies 31 through the communication hole 3103, and the other end of the buffer duct 32 is arranged along the communication groove 3102 and connected to the other buffer body 31 through the communication hole 3103.

[0028] As can be understood by those skilled in the art, when the buffer member 30 is compressed by the gravity of the car 11, the upper buffer body 31 is compressed first, so that the fluid in the compression space 3101 enters the buffer pipe 32 through the communication hole 3103, and is flushed into the compression space 3101 of the lower buffer body 31 by the buffer pipe 32. At this time, the fluid in the compression space 3101 moves with a reduced cross-sectional area, which causes the fluid to generate resistance to buffer the pressure of the car 11. Since the two buffer bodies 31 are in a superimposed state, the lower buffer body 31 is also compressed, which causes the fluid in the compression space 3101 of the lower buffer body 31 and the fluid in the buffer pipe 32 to collide during compression, slowing down the flow rate of the fluid in the upper buffer body 31, further enhancing the resistance generated by the fluid, and at the same time, the flow rate of the fluid in the lower buffer body 31 is also slowed down, so that the buffering effect of the entire buffer member 30 is enhanced. Moreover, the buffer member 30 will not be compressed to the bottom, and the car 11 of the elevator as a whole will not produce a sense of impact, and will not have a bad impact on the people inside the elevator, such as being startled.

[0029] Preferably, the buffer body 31 comprises a folding shell 311 and a resilient member 312, wherein the compression space 3101, the communication groove 3102 and the communication hole 3103 are all formed by the folding shell 311 which can be folded and compressed. The resilient member 312 is installed in the compression space 3101 and the two ends of the resilient member 312 abut against the upper and lower inner walls of the folding shell 311, respectively. In this way, when the folding shell 311 is compressed, the resilient member 312 is also in a compressed state, and under the condition of no external force, the resilient member 312 recovers to drive the folding shell 311 to restore.

[0030] Preferably, the side walls of the folding shell 311 of the buffer body 31 are foldably arranged in a wavy shape, and when the buffer body 31 is compressed, the side walls of the folding shell 311 of the buffer body 31 in the same vertical direction overlap along the folds, facilitating the compression of the folding shell 311 of the buffer body 31, and facilitating the installation personnel to carry after disassembly.

[0031] Preferably, the buffer body 31 further comprises a folding inner shell 313, which is installed in the compression space 3101, and the resilient member 312 is installed in the folding inner shell 313, and the internal space of the folding inner shell 313 is adapted to the resilient member 312, so that the resilient member 312 will not be skewed in the compression space 3101.

[0032] Preferably, the side wall of the folding inner shell 313 is provided with a wave shape which can be folded outwardly, the cross-sectional area of the folding inner shell 313 is smaller than that of the folding outer shell 311 and larger than that of the elastic member 312. When the buffer body 31 is compressed, the side walls of the folding inner shell 313 in the same vertical direction overlap along the folds, avoiding the folding inner shell 313 affecting the compression of the elastic member 312.

[0033] Preferably, the side wall of each buffer body 31 forms a side wall groove 3104, and the side wall groove 3104 of the lower buffer body 31 extends upward from the opening of the communication groove 3102 to the opening of the communication groove 3102 of the upper buffer body 31, so that when the two buffer bodies 31 are stacked, the two communication grooves 3102 are connected together through the side wall groove 3104, facilitating the placement of the buffer pipe 32.

[0034] Further preferably, the communication grooves 3102 of at least two stacked buffer bodies 31 are arranged to extend in the same direction, and the side wall groove 3104 is arranged vertically, so that the openings of the upper and lower communication grooves 3102 correspond, and the buffer pipe 32 enters the lower communication groove 3102 through the side wall groove 3104 of the upper communication groove 3102, shortening the length of the side wall groove 3104, and avoiding the buffer pipe 32 winding around the outer wall of the buffer body 31 to hinder the flow of fluid in the compression space 3101.

[0035] Preferably, the number of buffer members 30 in the elevator with buffer members is implemented as two, and the two buffer members 30 are arranged at a predetermined distance from each other and arranged at the bottom of the elevator shaft 90, thereby enhancing the buffering capacity.

[0036] Further preferably, the number of buffer bodies 31 of each buffer member 30 is arranged as three, and the three buffer bodies 31 are stacked together and connected through the buffer pipe 32, so that the fluid in the compression space 3101 of each buffer body 31 flows into the other two buffer bodies 31, and since the uppermost buffer body 31 is compressed first, the position with the most fluid is in the lowermost buffer body 31, thereby making the resistance of the lowermost buffer body 31 greater.

[0037] Preferably, the driving assembly 20 comprises a driving member 21 and a connecting member 22, wherein the driving member 21 is installed above the elevator shaft 90, one end of the connecting member 22 is drivingly connected to the driving member 21, and the other end of the connecting member 22 is connected to the car 11, so that the car 11 is driven by the connecting member 22 to perform lifting operation along the car track 12.

[0038] As an example, the driving member 21 is implemented to comprise a driving motor. The connecting member 22 is implemented to comprise a steel wire rope.

[0039] Preferably, the elevator with buffer member further comprises a pair of counterweight members 40, which comprises a pair of counterweight blocks 41 and a pair of counterweight frames 42, wherein the pair of counterweight frames 42 is fixed in the sliding space 901 of the elevator shaft 90, and the extending direction of the pair of counterweight frames 42 is arranged to be the same as the extending direction of the car track 12. The pair of counterweight blocks 41 is slidingly installed on the pair of counterweight frames 42, and one end of the connecting member 22 is connected above the pair of counterweight blocks 41, and the other end of the connecting member 22 is connected to the car 11 through the driving member 21, so as to balance the weight of the car 11 and reduce the power of the driving member 21.

[0040] As an example, the pair of counterweight blocks 41 is implemented to comprise counterweight blocks.

[0041] Preferably, the number of the buffer members 30 of the elevator with buffer member is arranged to be four, wherein two of the buffer members 30 are installed at the bottom of the elevator shaft 90 and below the car 11, and the other two of the buffer members 30 are installed at the bottom of the elevator shaft 90 and below the pair of counterweight blocks 41, so that the pair of counterweight blocks 41 is also buffered by the buffer members 30 when falling, avoiding the pair of counterweight blocks 41 and the elevator shaft 90 from colliding with each other and being damaged.

[0042] Those skilled in the art should understand that the above description and the embodiments of the utility model shown in the drawings are only examples and do not limit the utility model. The advantages of the utility model have been fully and effectively realized. The functions and structural principles of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can be any deformation or modification without departing from the principles.
