[0002] The car bottom generally refers to the bottom of the elevator shaft. This part is also very important for elevator protection. The car bottom mainly contains mechanical safety protection devices. Regularly inspecting and maintaining these safety devices not only improves elevator safety but also plays a significant role in elevator maintenance. When inspecting the car bottom safety devices, attention should be paid to scratches, corrosion, or aging, and corrugated pipes and other parts should be replaced promptly.

[0003] Chinese Patent CN207524785U discloses an elevator car bottom, relating to the field of elevator technology. The bottom includes a frame, a car bottom plate disposed within the area enclosed by the four sides of the frame, and a functional device. The functional device includes a weighting part and a fixing part. The weighting part includes a weighting rib, a weighting block disposed within the weighting rib, and a cover plate for covering the weighting rib. The frame has a sliding groove for the cover plate to slide. The fixing part includes longitudinal reinforcing ribs for separating and fixing the cover plate and large reinforcing ribs for connecting the frame and the cover plate respectively. This elevator car bottom structure is simple, saves materials, is easy to process, has high overall stability, and is easy to install.

[0004] The existing elevator car has a problem where, when people ride in the elevator, there is a braking force when the elevator descends to a stop. This braking force can cause discomfort to people in the elevator, and in severe cases, it can cause dizziness and vomiting. This results in a lack of comfort in the elevator, making it impractical when it is put into use.

[0005] Therefore, a car bottom bracket and an elevator car bottom are proposed to address the above problems. Utility Model Content

This braking force can cause physical discomfort to people in the elevator, and in severe cases, dizziness and vomiting. As a result, the elevator lacks comfort and is not practical when it is put into use.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The elevator car bottom bracket and elevator car bottom of this utility model include a car bottom bracket connecting plate, a buffer support assembly installed at the bottom of the car bottom bracket connecting plate, a first support rod fixedly connected to the top of the car bottom bracket connecting plate, and a second support rod fixedly connected to the side of the first support rod; the buffer support assembly includes a mounting shell, a hydraulic shock absorber rod installed inside the mounting shell, a first spring fixedly connected to the bottom of the mounting shell, a connecting block fixedly connected to the bottom of the first spring, and a support block fixedly connected to the bottom of the connecting block.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 3 As shown, a car bottom bracket includes a car bottom bracket connecting plate 1. A buffer support assembly 2 is installed at the bottom of the car bottom bracket connecting plate 1, and a first support rod 3 is fixedly connected to the top of the car bottom bracket connecting plate 1. A second support rod 4 is fixedly connected to the side of the first support rod 3. The buffer support assembly 2 includes a mounting shell 201. The buffer support assembly 2 can increase the comfort of passengers riding the elevator. A connecting block 204 forms an elastic structure with the mounting shell 201 through a first spring 203. The mounting shell 201 is evenly spaced about the bottom of the car bottom bracket connecting plate 1. When the elevator descends to the lowest floor, the buffer support assembly 2 contacts the ground. At this time, the hydraulic shock absorber 202 will be squeezed by the hydraulic oil inside to provide a shock absorption effect. At the same time, the connecting block 204 will squeeze the first spring 203, thereby providing a buffering effect and increasing the comfort of passengers riding the elevator.

[0027] Please see Figure 1 and Figure 2 As shown, a car bottom bracket has a first support rod 3, a second support rod 4, and a car bottom bracket connecting plate 1 forming a right triangle with the car bottom bracket connecting plate 1 and the first support rod 3 as the right angle sides. The first support rod 3 and the second support rod 4 are equally spaced about the top of the car bottom bracket connecting plate 1. The triangular support structure can provide stability, making the elevator car bottom more stable.

[0028] Please see Figure 1 , Figure 4 and Figure 5As shown, an elevator car bottom also includes a connecting shell 5. A buffer control assembly 6 is installed inside the connecting shell 5, and a shock-absorbing pad 7 is provided on the top of the buffer control assembly 6. The buffer control assembly 6 includes a second spring 601. The buffer control assembly 6 provides a buffering effect, increasing the comfort of the elevator. A control rod 604 forms a rotating structure with a second connecting lug 606 via a second rotating shaft 607, and also forms a rotating structure with a first connecting lug 602 via a first rotating shaft 603. The first connecting lug 602 forms an elastic structure with the connecting shell 5 via the second spring 601. The second spring 601, first connecting lug 602, first rotating shaft 603, control rod 604, second connecting lug 606, and second rotating shaft 607 are all symmetrically arranged in twos about the vertical central axis of the connecting shell 5. When the elevator experiences a downward force, the elevator car descends with the mounting plate 608, causing the control rod 604 to compress multiple springs and rotate, providing a buffering effect and increasing the comfort of the elevator.

[0029] Please see Figure 1 and Figure 4 As shown, in an elevator car bottom, the shock-absorbing pad 7 and the mounting plate 608 are tightly fitted together, and the material of the shock-absorbing pad 7 is set as ACF ultimate shock-absorbing material; ACF ultimate buffer material has extremely strong shock absorption performance, can absorb impact force, and instantly convert impact energy into insignificant heat energy.

[0030] Working principle: First, when the elevator descends, the elevator car connects with the shock-absorbing pad 7 and the mounting plate 608. The descent of the elevator will cause the elevator car to tend to press down on the mounting plate 608. At this time, the downward movement of the mounting plate 608 will cause the control rod 604 to rotate through the first rotating shaft 603 and the second rotating shaft 607. At the same time, the second spring 601 and the third spring 605 will provide a buffering effect. Then, when the elevator descends to the bottom floor, the buffer support assembly 2 contacts the ground. At this time, the hydraulic shock absorber 202 will squeeze the hydraulic oil inside, and at the same time, the connecting block 204 will squeeze the first spring 203 upward. This will also make the elevator landing more smoothly.

[0031] Next, when the elevator descends to the ground floor, the vibration generated will be absorbed by the shock-absorbing pad 7 as it is transmitted to the car, so that the people in the car will not feel a large vibration. At the same time, the triangular support structure formed by the first support rod 3, the second support rod 4 and the car bottom bracket connecting plate 1 will make the elevator car bottom more stable and prevent damage to the elevator car bottom caused by long-term operation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
