The car floor assembly, a crucial component of the elevator, bears the entire weight and significantly impacts customer perception and evaluation. In today's fiercely competitive environment, achieving product functionality while ensuring component safety and reliability at minimal cost has become a primary objective for every manufacturer and technical development team.

[0003] In current elevator technology, the car bottom assembly is basically composed of two main parts: the car bottom and the bracket. When assembling with the car frame, it is done through the mounting holes on the side beams of the bracket. The mounting holes are generally located on both sides of the car bottom assembly, near the middle.

[0004] Existing technologies typically consist of two main parts: the car floor and the bracket. The car floor and bracket are assembled using bolts. The side beams on the bracket have elongated holes in the middle, which are then connected to the car frame via bolts. This makes it impossible to directly connect the car floor to the car frame without using the bracket, resulting in a slightly complex overall structure, heavier components, and higher manufacturing costs. Therefore, a novel front-to-rear connected bracketless car floor assembly is proposed to address these issues. Utility Model Content

[0017] Reference Figures 1-3This utility model provides an embodiment of a novel front-to-rear connected bracketless car bottom assembly, including a main upright beam 1 and a secondary upright beam 2. The main upright beam 1 and secondary upright beam 2 form the car frame. The car bottom assembly 3 is connected to the car frame via left and right side frames 33 and a car bottom support plate 36. The car guide rail is located at the rear of the car, not in the middle of the conventional sides of the car. The car bottom assembly 3 is provided at the bottom of the main upright beam 1. The car bottom assembly 3 includes a car bottom support plate 36, which is made of a certain thickness of plate and provides a certain degree of reinforcement to the entire car bottom assembly 3. One end of the support plate has three rows of round holes. The entire car bottom assembly 3 is assembled to the rear side of the car frame via round holes and screws and nuts. The car's guide rails are located on the rear side, in the unconventional design of the middle two sides of the car. The ends of the car bottom support plates 36 are fixedly connected to the outer wall of the main upright beam 1. Two sets of car bottom support plates 36 are provided, with a buffer assembly 4 between them. Both sets of car bottom support plates 36 have frame panels 33 fixedly connected to their outer walls. The frame panels 33 form the outer frame of the car bottom assembly 3, providing overall support. A front beam 34 is fixedly connected to the front of the frame panels 33, and welding nuts are welded onto the front beam 34. The front wall assembly of the car is fixed by welding nuts. A car floor plate 32 is fixed to the top of the frame 33 and the front beam 34. The car floor plate 32 has car wall connection holes for connection to the car wall. It has a folded edge at the front end; if needed, a sill connection hole can be made on the folded edge for fixing the sill assembly. A PVC floor 31 is fixedly connected to the top of the car floor plate 32. Various samples of the PVC floor 31 are available for customers to choose from; customers can select their preferred sample according to their needs.

The two sets of car bottom support plates 36 are fixedly connected by reinforcing ribs 37. The reinforcing ribs 37 are arranged horizontally under the car bottom assembly 3, which plays a major role in strengthening the entire car bottom assembly 3 and providing safety protection. There are four sets of reinforcing ribs 37. The middle two sets of reinforcing ribs 37 are fixedly connected to a fixing plate 38. The fixing plate 38 plays a role in fixing the cables when the car is moving up and down. The bottom of the main upright beam 1 is fixedly connected to the end of the car bottom support plate 36, and the bottom of the secondary upright beam 2 is fixedly connected to the outer wall of the mounting plate 35. The front end of the car bottom support plate 36 is fixedly connected to the back of the front beam 34.

[0018] Reference Figures 4-5The buffer assembly 4 includes a buffer fixing seat 41. The buffer fixing seat 41 is provided with buffer reinforcing ribs on its outer extension and is welded to the fixing seat plate 44 as a whole to strengthen it and prevent the buffer 43 from being severely deformed when it is impacted. The buffer fixing seat 41 is fixedly connected between two sets of car bottom support plates 36. The buffer 43 is connected to the top of the buffer fixing seat 41 by bolts 42. The buffer 43 is made of soft rubber material and plays a buffering role for the entire car at certain times. The bottom of the buffer fixing seat 41 is fixedly connected to the fixing seat plate 44. The fixing seat plate 44 is welded to the buffer fixing seat 41 to make the entire buffer assembly 4 in a U-shape to increase the compressive strength. The bolts 42 are threadedly connected to the inner wall of the buffer fixing seat 41 and the bottom inner wall of the buffer 43. The two ends of the fixing seat plate 44 are fixedly connected to the inner walls of the two sets of car bottom support plates 36.

[0019] Working Principle: In operation, the novel front-to-rear connected bracketless car bottom assembly 3 uses the main upright beam 1 and secondary upright beam 2 as the car frame, providing basic support for the entire car structure. The car bottom assembly 3 is connected to the car frame via left and right side frames 33 and a car bottom support plate 36. The car bottom support plate 36, made of a certain thickness of sheet metal, not only strengthens the entire car bottom assembly 3, but also features three rows of round holes at one end that, when fitted with screws and nuts, securely assemble the entire car bottom assembly 3 to the rear side of the car frame. Simultaneously, because the car guide rails are located at the rear of the car, rather than in the unconventional middle section of the car's sides, this layout provides more stable guidance during car operation, reducing swaying. In the car bottom assembly 3, the ends of two sets of car bottom support plates 36 are fixedly connected to the outer wall of the main upright beam 1, and the front ends are fixedly connected to the back of the front beam 34. The frame 33 is fixedly connected to the outer wall of the two sets of car bottom support plates 36. The front beam 34 is fixed to the front of the frame 33. The welding nuts on the front beam 34 are used to fix the front wall assembly of the car. The car bottom plate 32, which is fixed to the top of the frame 33 and the front beam 34, is connected to the car wall through the car wall connection hole on it. The folded edge at the front end of the car bottom plate 32 can be opened with a sill connection hole when needed to fix the sill assembly. The PVC floor 31 fixed to the top of the car bottom plate 32 provides a load-bearing surface for the interior of the car to meet the needs of passenger or cargo placement. The mounting plate 35, which is fixedly connected to the inner wall of the frame 33, is welded to the inner wall of the frame 33, further strengthening the structural strength of the frame 33. The bottom of the auxiliary upright beam 2 is fixedly connected to the outer wall of the mounting plate 35, enhancing the stability of the connection between the car frame and the car bottom assembly 3. In addition, the two sets of car bottom support plates 36 are fixedly connected by four sets of horizontally arranged reinforcing ribs 37. These reinforcing ribs 37 play a major role in strengthening the entire car bottom assembly 3, ensuring the safe operation of the car. The fixing plate 38, which is fixedly connected between the middle of the two sets of reinforcing ribs 37, can effectively fix the cables when the car is running up and down, preventing the cables from getting tangled or falling off and affecting the operation of the car. The buffer assembly 4 is installed between the two sets of car bottom support plates 36, playing a crucial role when the car reaches a specific position or in case of an emergency. The buffer reinforcing ribs extending from the buffer fixing seat 41 are integrally welded to the fixing seat plate 44, preventing severe deformation of the buffer 43 upon impact. The fixing seat plate 44 and the buffer fixing seat 41 are welded opposite each other, making the entire buffer assembly 4 U-shaped, greatly increasing its compressive strength. The top of the buffer fixing seat 41 is connected to the buffer 43 via bolts 42. When the car encounters an emergency requiring buffering, the buffer 43 effectively absorbs the impact force, providing cushioning protection for the entire car. The two ends of the fixing seat plate 44 are fixedly connected to the inner walls of the two sets of car bottom support plates 36, ensuring the stability of the buffer assembly 4 during operation.
