Description

Technical Field

[0001] This utility model relates to an improvement of a platform elevator, specifically a platform-type home elevator car bottom structure. Background Technology

[0002] Platform elevators are a structural form that differs from traditional elevators. Their main feature is the use of a non-fully enclosed car structure, primarily employing a platform structure that can move up and down. Without the enclosed car and shaft environment, a greater sense of space can be achieved, which is particularly important for families with limited space. Therefore, platform elevators are increasingly being introduced into residential buildings. However, platform elevators are relatively less safe than traditional elevators and require more safety devices, thus necessitating improvements tailored to the home environment. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a platform-type home elevator car bottom structure.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the elevator car bottom structure includes a base plate structure and a car bottom structure. The base plate structure and the car bottom structure form an angle structure that is close to a right angle. The base plate structure is connected to the drive device. The car bottom structure is set as the floor surface of the car in the space where the elevator runs. The upper surface of the car bottom structure is covered with a floor board. The side of the car bottom structure is provided with a sensing edge. The sensing edge senses the pressure state at the edge of the car bottom structure and is connected to the control circuit of the elevator. The sensing edge is set at the other three edges of the car wall structure, except for the one connected to the base plate structure. The main structure of a platform-type home elevator consists of a base plate structure and a car bottom structure. The base plate structure is connected to the drive equipment, providing the driving function for operation. The car bottom structure is the ground foundation structure inside the elevator. A sensing edge is set on the side of the car bottom structure. Because there is a danger if the elevator is near the edge during operation, the sensing edge is set to detect the safety function. When the sensing edge senses pressure, the elevator's drive equipment will stop running. After leaving the edge position, the sensing edge resets, and the elevator can continue to run, increasing the safety of elevator operation and making it more reassuring to use. Since there is a blockage on the side of the base plate structure connected to the base plate structure, setting sensing edges on the other three sides is sufficient to meet the safety requirements.

[0005] Furthermore, the sensing edge includes a pressure-bearing edge strip and pressure-sensitive components. The pressure-bearing edge strip is disposed on the horizontal edge of the car bottom structure and surrounds the side edge of the car bottom structure. Multiple pressure-sensitive components are disposed inside the pressure-bearing edge strip and are distributed near the corners of the car bottom structure. When the pressure-bearing edge strip is compressed, it triggers the pressure-sensitive components, which then transmit signals to the elevator control circuit. The pressure-bearing edge strip and the car bottom structure are relatively separate structures, connected through the pressure-sensitive components. When the pressure-sensitive components are subjected to pressure, they generate an electrical signal, which connects to the elevator's operating circuit to control the elevator's stopping and starting.

[0006] Furthermore, the pressure-sensitive component includes a base plate, a pressure spring, a guide stud, a trigger rod, and a micro switch. The base plate extends from the car bottom structure. A pressure spring and a guide stud are mounted on the base plate. One end of the guide stud is connected to the pressure-bearing edge strip, and the other end is connected to the base plate. The pressure-bearing edge strip and the base plate are elastically supported by the pressure spring. A trigger rod is fixed to the pressure-bearing edge strip and moves with it. A micro switch is fixed to the car bottom structure. When the pressure-bearing edge strip is pressed downwards, it moves the trigger rod to contact and trigger the micro switch. The pressure-sensitive component uses an elastic pressure-bearing structure. The guide stud guides the vertical movement of the pressure-bearing edge strip. After being pressed downwards, the pressure-bearing edge strip moves linearly along the guide stud, simultaneously driving the trigger rod. Upon contact with the micro switch, an electrical signal is generated, realizing the sensing of pressure. After the pressure is released, the pressure spring causes the pressure-bearing edge strip to return to its original position, the trigger rod disengages from the micro switch, and the elevator can continue to operate.

[0007] Furthermore, a light-transmitting hole is provided on the side of the pressure-bearing edge strip, and a light-transmitting plate is provided covering the light-transmitting hole. An LED light strip is correspondingly provided on the inner side of the pressure-bearing edge strip, and the LED light strip is connected to a micro-switch circuit. The light-transmitting hole and LED light strip on the pressure-bearing edge strip provide a visual reminder. When the pressure-bearing edge strip is under pressure, the pressure-sensitive component will simultaneously illuminate the LED light strip, which can remind the elevator that it is in a safety protection state through flashing, bright colors, or other means.

[0008] Furthermore, the included angle between the base plate structure and the car bottom structure is set to 88° to 89.9°. The base plate structure and the car bottom structure are fixedly connected by stiffening plates. The edge of the car bottom plate structure away from the base plate structure is 5 to 8 mm higher than the reference plane. Since the design requires that the floor tilt of the elevator not exceed ±10 mm of the reference plane when fully loaded, the included angle is slightly less than a right angle during design and manufacturing, and the far end is within the error range of the reference plane. It is reinforced by stiffening plate structure to control the tilt within the required range.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is a platform-type elevator improvement that can be applied to home use. It has high safety and reliable safety protection, which can prevent passengers from approaching the edge. It also has obvious warning features to prevent foreign objects from getting stuck in the gaps at the edge, thus avoiding structural damage and improving user comfort. Attached Figure Description
