[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] As Figures 1-6 shown;

[0031] An elevator car pedal structure includes a pedal 1. Limiting angle members 2 are provided at the four corners of the pedal 1. Buffer components 3 are provided at the four corners of the bottom of the pedal 1. The bottom of the buffer component 3 is connected to the limiting angle member 2. A shock absorption component 4 is provided on one side of the buffer component 3. The shock absorption component 4 is arranged between the pedal 1 and the limiting angle member 2.

[0032] In this implementation: It is found that the publication (announcement) number: 202322212069.8 discloses an elevator car pedal structure. In this technology, it is disclosed that "including a pedal, a rotating plate is rotatably connected to the inner wall of the pedal, and a locking mechanism is arranged on one side of the rotating plate; a telescopic rod, a rotating mechanism is arranged at the left end of the telescopic rod, and a round rod is arranged inside the rotating mechanism. The design structure of the present invention is reasonable. It can drive the round rod to move leftward through the rotating mechanism by setting components such as a fixed strip and a soft strip. The round rod drives the fixed strip to approach and press the side of the floor, causing the round rod to rotate, so that the fixed strip and the soft strip block the gap between the pedal and the side of the floor, achieving the effect of blocking the gap, thus solving the problem that there are gaps between the pedal and the floor of the floor. During the process of passengers entering and leaving the elevator, small items are likely to fall through the gaps, which is inconvenient to take out, and the gaps are also likely to catch the heels of passengers wearing high heels, causing the risk of spraining the ankle.";

[0033] When an existing elevator car pedal structure is in use, during the process of passengers entering and leaving the elevator, small items are likely to fall through the gaps, which is inconvenient to take out. The gaps are also likely to catch the heels of passengers wearing high heels, causing the risk of spraining the ankle. Considering the actual use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a spring and a retractable component are added to this application document.

[0034] According to the above content, in order to solve the problem that there will be gaps between the pedal and the floor of the floor, during the process of passengers getting in and out of the elevator, it is easy for some small items to fall through the gaps, which is inconvenient to take out. The gaps are also likely to catch the heels of passengers wearing high heels, posing a risk of sprained ankles. It also includes a pedal 1. At the four corners of the pedal 1, there are limit angle members 2. At the four corners of the bottom of the pedal 1, there is a buffer assembly 3. The bottom of the buffer assembly 3 is connected to the limit angle member 2. On one side of the buffer assembly 3, there is a shock absorption assembly 4. The shock absorption assembly 4 is arranged between the pedal 1 and the limit angle member 2.

[0035] Specifically, at the position near the top of the inner wall of the limit angle member 2, there is a retaining strip 5. The position and structure of the retaining strip 5 correspond to those of the pedal 1. The retaining strip 5 can limit the displacement distance of the pedal 1 and prevent the pedal 1 from continuously shaking up and down. The retaining strip 5 can be set as a rubber strip.

[0036] Furthermore, a connecting rod 6 is fixedly connected between adjacent limit angle members 2. At the bottom of the pedal 1, there are reinforcing ribs 7 arranged in a criss-cross pattern to enhance the anti-bending ability of the pedal 1.

[0037] Still further, the buffer assembly 3 includes a cylinder body 301 fixedly connected to the limit angle member 2. Inside the cylinder body 301, there is a movable plate 302. The bottom of the movable plate 302 is connected to a buffer spring 303. The top of the movable plate 302 is fixedly connected to a movable column 304. The top end of the movable column 304 penetrates through the cylinder body 301 and is connected to the pedal 1. When a passenger steps on the pedal 1, the pedal 1 can displace downward by a certain distance to buffer, and the downward impact force is absorbed by the buffer spring 303, thereby reducing the impact on the car and avoiding the car from shaking.

[0038] It should be noted that at the four corners of the top of the pedal 1, there are sinking grooves 8. Inside the sinking grooves 8, there are fixing bolts 9. The fixing bolts 9 penetrate through the pedal 1 and are threadedly connected to the movable column 304.

[0039] It should be noted that at the top of the movable column 304, there is a threaded groove 10. The threaded groove 10 is threadedly connected to the fixing bolt 9. Inside the sinking groove 8, there is a cover plate 11. The cover plate 11 is arranged above the fixing bolt 9.

[0040] It is worth introducing that the shock absorption assembly 4 includes a fixing ring 401 fixedly connected to the limit angle member 2. Inside the fixing ring 401, there is a rubber block 402. In the middle position of the rubber block 402, there is an air pressure cavity 403. Inside the air pressure cavity 403, there is a rubber column 404. The top of the rubber column 404 is fixedly connected to the pedal 1. The shock absorption assembly 4 forms a damping effect when the pedal 1 displaces downward. On the one hand, it can absorb vibrations and reduce the vibration transmission to the car. On the other hand, it can play a damping role and prevent the pedal 1 from shaking up and down significantly.

[0041] Working principle and usage process of the utility model: The limit angle piece 2 is fixedly connected to the elevator car. When a passenger with a relatively large body weight or carrying heavy objects steps on the pedal 1, a downward impact force will be applied to the pedal 1. At this time, the buffer assembly 3 contracts, and the buffer spring 303 in the cylinder body 301 is in a compressed state to absorb the impact force transmitted by the pedal 1 and prevent the impact force from being transmitted to the car and causing the car to shake. At the same time, the rubber column 404 of the shock absorption assembly 4 moves downward in the air pressure chamber 403, and the air in the air pressure chamber 403 forms a resistance to resist the downward movement of the pedal 1 to form a damping effect. The rubber block 402 and the rubber column 404 of the shock absorption assembly 4 will deform to absorb a stronger impact force. When it is necessary to disassemble the pedal 1, pry out the cover plate 11 in the sunk groove 8 and rotate the fixing bolt 9 to make it leave the thread groove 10 at the top of the movable column 304, then the pedal 1 can be removed to facilitate the maintenance of the bottom structure of the pedal 1.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
