Detailed Description

The essential features of the invention will be further explained below with reference to the drawings and the detailed description of the invention.

As shown in fig. 1 and 2, the car with the guide assembly is composed of a car body with a bottom plate 1 and glass side plates, a safety assembly is arranged on the periphery of the bottom plate 1, the safety assembly comprises a micro switch 2 and a safety edge 3 capable of triggering the micro switch 2, the safety edge 3 controls the car to stop running by triggering the micro switch 2 when falling under a force, a guide assembly 4 is arranged on the safety edge 3, and the guide assembly 4 guides the safety edge 3 to ascend and descend along a preset path, so that the micro switch 2 is switched between a triggering state and an idle state. Guide 3 goes up and down to safe limit through setting up guide assembly 4, ensure that safe limit 3 can follow the accurate lift of predetermineeing the route, both guarantee that safe limit 3 can trigger micro-gap switch 2 through the whereabouts, and then stop through the control car and go up and down to ensure passenger's safety, can also break away from safe limit 3 back accurate reset and break away from with micro-gap switch 2 at the passenger, ensure that the car can reply the lift operation, promote and use the reliability.

In actual operation, the local lateral wall of car is the glass curb plate for the passenger can vwatch the car scenery through the glass curb plate in the car. Because there is the not good enough problem of structural strength in the glass curb plate, in order to prevent that the glass curb plate from taking place the damaged condition because of the passenger relies on, set up safe limit 3 in the edge that bottom plate 1 and glass curb plate correspond and ensure passenger's safety.

In actual operation, the guide assembly 4 comprises a seat cover 6 arranged on the outer side wall of the bottom plate 1 and a guide rod 5 arranged on the bottom surface of the safety edge 3, wherein a guide hole 7 with an axis vertical to the top surface and opened upwards is formed in the top surface of the seat cover 6, and the guide rod 5 is vertically inserted into the guide hole 7 and guides the safety edge 3 to vertically lift. And a return spring 8 is arranged in the guide hole 7, and the safety edge 3 falls and extrudes the return spring 8, so that the return spring 8 accumulates pretightening force for driving the safety edge 3 to return upwards to be separated from the microswitch 2.

When assembling the guide assembly 4, firstly, the return spring 8 is inserted into the guide hole 7, and then the guide rod 5 is vertically inserted into the return spring 8, so that the bottom end of the guide rod 5 is always inserted into the guide hole 7 and the return spring 8 is radially limited.

After the installation is finished, the reset spring 8 and the guide hole 7 are coaxially arranged, and the guide rod 5 can ascend and descend along the axis of the reset spring 8. The safety edge 3 is arranged along the periphery of the bottom plate 1, and the top surface of the safety edge 3 is exposed in the inner cavity of the lift car. And a microswitch 2 and a guide component 4 are arranged below the safety edge 3, so that the safety edge 3 can lift along a preset path and control the car to start and stop for switching.

Specifically, when the passenger is located in the middle of the car and does not contact the safety edge 3 (as shown in fig. 3), the safety edge 3 will rise under the urging of the return spring 8 and disengage from the microswitch 2, and at this time, the microswitch 2 is in an idle state, and the car can be powered on to rise and fall.

When a passenger moves towards the side wall of the glass of the car and steps on the safety edge 3 (as shown in fig. 4), the safety edge 3 can fall due to the gravity from the passenger, in the process, the guide rod 5 falls along the axis of the guide hole 7 to ensure the vertical displacement of the safety edge 3, the reset spring 8 circumferentially contracts under the extrusion action of the bottom walls of the connecting plate 9 and the guide hole 7 and accumulates the pretightening force for driving the safety edge 3 to upwards reset, the bottom surface of the safety edge 3 is in contact with the trigger 10, so that the microswitch 2 is switched to a trigger state from an idle state and controls the car to stop lifting, a warning effect can be provided for the passenger to remind the passenger to keep away from the glass side plate, the passenger can be effectively prevented from depending on the glass side plate due to the lifting of the car, the possibility of damaging the glass side plate is reduced, and the safety of the passenger is ensured.

When a passenger is far away from the glass side wall and is separated from the safety edge 3, the safety edge 3 can reset upwards along the axis of the guide hole 7 under the action of the reset spring 8, so that the microswitch 2 can be switched from a triggering state to an idle state, and the lift car can be ensured to be electrified and operated.

In actual operation, the guide rod 5 is inserted into the guide hole 7 to a depth greater than the lifting distance of the safety edge 3, so that the guide rod 5 is always inserted into the guide hole 7 when the safety edge 3 is lifted. The guide rod 5 is inserted into the guide hole 7 when the safety edge 3 falls under stress or resets upwards, so that the guide hole 7 can be ensured to perform radial limitation on the guide rod 5 through the return spring 8 all the time. And a space for lifting the safety edge 3 is reserved between the connecting plate 9 and the orifice of the guide hole 7, so that the safety edge 3 can trigger the micro switch 2 when falling under stress.

In actual operation, a connecting plate 9 is arranged at the top of the guide rod 5, and the connecting plate 9 is attached and fixedly connected with the bottom surface of the safety edge 3, so that the axis of the guide rod 5 is perpendicular to the bottom surface of the safety edge 3. The 5 axes of guide rod and the 9 bottom surfaces of connecting plate are mutually perpendicular and set up, ensure that guide rod 5 can contradict with reset spring 8 and guide the vertical lift of safe limit 3, prevent safe limit 3 because of horizontal migration or slope take place the dead condition of card.

In actual operation, the diameter of the connecting plate 9 is larger than that of the guide hole 7, and the connecting plate 9 vertically and completely covers the return spring 8 in the guide hole 7, so that the safety edge 3 drives the return spring 8 to be compressed and deformed through the connecting plate 9 when falling. Increase its area of contact with safe 3 within a definite time through increasing the 9 sizes of connecting plate, and then effectively promote the relative position relation between guide rod 5 and safe 3 within a definite time, guarantee that guide rod 5 axis is perpendicular to connecting plate 9 settings all the time, promote the guide precision of guide subassembly 4.

In practice, the return spring 8 is clamped between the outer side wall of the guide rod 5 and the inner side wall of the guide hole 7 so that the guide rod 5 is radially restrained. The radial cross section profile between 7 inside walls of bullport and 5 outside walls of guide rod matches with reset spring 8's radial cross section profile, has both made things convenient for reset spring 8 to carry out the axial and has stretched out and draw back, can also effectively restrict guide rod 5 and take place the level to the skew.

In practical operation, the micro switch 2 is fixedly connected to the outer side wall of the bottom plate 1, and a trigger 10 capable of contacting with the safety edge 3 is arranged at the top of the micro switch 2. The base plate 1 provides a stable support for the microswitch 2, ensuring that the safety edge 3 accurately triggers the microswitch 2 when stressed and falling relative to the base plate 1.

In practical operation, the safety edge 3 is in a shape of a letter 21274and is arranged around the periphery of the bottom plate 1, and the compartment body comprises a glass side plate corresponding to the safety edge 3. The micro switches 2 are arranged in a plurality and are arranged along the safety edge 3. The three lateral wall of car uses the glass curb plate for safe limit 3 needs along the three edge setting of bottom plate 1, forms safe limit 3 through integrated into one piece processing and promotes and trigger linkage nature, prevents to take place the condition that uncontrollable car shut down because of safe limit 3 atress district section corresponds micro-gap switch 2 and loses efficacy.
