[0033] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Reference Figures 1 to 4 This application provides an elevator car bottom structure, including a car body 1, a car bottom body 2 disposed below the car body 1, a disassembly and assembly assembly 3 fixedly installed at the bottom of the car body 1, and a buffer assembly 4 fixedly installed at the bottom of the car bottom body 2; the disassembly and assembly assembly 3 includes a connecting frame 31 and a locking rod 32, the connecting frame 31 is fixedly installed at the bottom of the car body 1, the locking rod 32 is slidably connected to both sides of the connecting frame 31, a locking groove 33 is opened on one side of the car bottom body 2, the locking rod 32 is engaged with the locking groove 33, a moving plate 34 is fixedly connected to one end of the locking rod 32, a spring 35 is fixedly connected to one side of the moving plate 34, the disassembly and assembly assembly 3 also includes a hollow tube 36 and a sliding rod 37, the hollow tube 36 is fixedly connected to the inner side wall of the connecting frame 31, the sliding rod 37 is fixedly connected to one side of the moving plate 34, the sliding rod 37 and the hollow tube 36 are slidably connected, the disassembly and assembly assembly 3 also includes a pull ring 38, the pull ring 38 is fixedly installed on one side of the moving plate 34.

[0035] In this embodiment, during installation: the car bottom body 2 is lifted to the corresponding position below the car body 1. The locking rod 32 extends under the elastic force of the spring 35. As it approaches, the locking rod 32 will be aligned with the locking groove 33 and locked in, achieving initial fixation. During this period, the sliding rod 37 slides in the hollow tube 36, which plays a guiding and limiting role to ensure accurate and reliable locking. During disassembly: the operator pulls the pull ring 38, which drives the moving plate 34 to make the locking rod 32 overcome the elastic force of the spring 35 and disengage from the locking groove 33, releasing the fixation. The car bottom body 2 can then be removed for convenient subsequent operations.

[0036] Reference Figures 1 to 4 In one aspect of this embodiment, the buffer assembly 4 includes a support frame 41 and a damper 42. The support frame 41 is fixedly installed at the bottom of the car bottom body 2. The damper 42 is fixedly connected to the inner top wall of the support frame 41. A second spring 43 is fixedly connected to the inner top wall of the support frame 41. Sliding blocks 44 are fixedly connected to the bottom ends of the second spring 43 and the damper 42, respectively. The buffer assembly 4 also includes a base plate 45, which is fixedly installed at the bottom of the sliding blocks 44. The buffer assembly 4 also includes an anti-slip pad 46, which is disposed at the bottom of the base plate 45. The buffer assembly 4 also includes a stabilizing groove 47, which is respectively opened on both sides of the support frame 41. The buffer assembly 4 also includes a stabilizing block 48, which is fixedly installed on both sides of the sliding block 44. The stabilizing block 48 is slidably connected to the stabilizing groove 47.

[0037] In this embodiment, during normal operation: During normal elevator operation, the weight borne by the car bottom is transmitted to the buffer assembly 4 via the support frame 41. Spring 43 is in a certain compressed state, providing support force to maintain stability. The damper 42 coordinates to adjust the extension resistance, buffering and suppressing minor vibrations. The sliding block 44 is stabilized under the action of both. The stabilizing blocks 48 on both sides slide in the stabilizing groove 47 to ensure accurate positioning and overall reliability. During impact: In cases of top-down or bottom-down impacts, the car bottom is subjected to a large impact force transmitted to the buffer assembly 4. Spring 43 is further compressed to absorb energy. The damper 42 enhances the damping force, dissipates the impact energy, and suppresses vibration. The sliding block 44 drives the stabilizing block 48 to move accordingly, coordinating to buffer and reduce the impact force and prevent damage to the car bottom. The anti-slip pad 46 at the bottom of the base plate 45 increases friction, ensuring structural stability during buffering and protecting the car and its interior safety.

[0038] Working principle: During installation: Lift the car bottom body 2 to the corresponding position below the car body 1. The locking rod 32 extends under the elastic force of the spring 35. As it approaches, the locking rod 32 will lock into the slot 33 after aligning with it, achieving initial fixation. During this process, the sliding rod 37 slides inside the hollow tube 36, which acts as a guide and limiter to ensure accurate and reliable locking. During disassembly: The operator pulls the pull ring 38, which moves the moving plate 34 to make the locking rod 32 overcome the elastic force of the spring 35 and disengage from the slot 33, releasing the fixation. The car bottom body 2 can then be removed for subsequent operations.

[0039] Normal operation: During normal elevator operation, the weight of the car bottom is transmitted to the buffer assembly 4 via the support frame 41. Spring 43 is in a certain compressed state, providing support force to maintain stability. The damper 42 adjusts the extension resistance to buffer and suppress minor vibrations. The sliding block 44 is stabilized under the action of both. The stabilizing blocks 48 on both sides slide in the stabilizing groove 47 to ensure accurate positioning and overall reliability. Impact: In case of top or bottom impact, the car bottom is subjected to a large impact force transmitted to the buffer assembly 4. Spring 43 is further compressed to absorb energy. The damper 42 increases the damping force to dissipate impact energy and suppress vibration. The sliding block 44 drives the stabilizing block 48 to move accordingly, working together to buffer and reduce the impact force and prevent damage to the car bottom. The anti-slip pad 46 at the bottom of the base plate 45 increases friction to ensure structural stability during buffering and protect the car and interior safety.
