Description

Technical Field

[0001] The utility model relates to the technical field of elevator parts and components, in particular to an elevator call button. Background Art

[0002] The elevator call button plays a key role in the elevator system. Its basic structure includes components such as a button cover, spring, trigger, switch mechanism and electrical contacts. When the passenger presses the button, the button cover is compressed, and the trigger closes the electrical contacts through the switch mechanism to complete the circuit connection. This closed circuit sends a request signal to the elevator control system, indicating that a specific floor requires elevator service. The spring ensures that the button rebounds to its original position after being released, and the cable connects the button to the elevator control system. The indicator light on the button can show whether the elevator has received the request, but the current elevator call button mainly uses a spring-based reset structure to force the button to reset. After long-term use, the spring elasticity gradually decreases, resulting in the button rebounding weakly or unable to reset completely, thus affecting the normal function of the button. At this time, the user needs additional pressing force or multiple presses to ensure that the button is pressed, which reduces the user experience and causes inconvenience and delays in elevator calls.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The rod-type elastic reset structure 12 includes an arc-shaped support arm 1201 fixed to one side of the bottom of the cylindrical hollow shell 1, and a triangular seat 1202 installed on the outer wall of the arc-shaped support arm 1201 away from the center point of the cylindrical hollow shell 1, an arc-shaped piece 1204 is rotatably installed on the outer wall of the triangular seat 1202 close to the center point of the cylindrical hollow shell 1, and a rotating shaft 1203 is rotatably installed on the outer wall of one side of the triangular seat 1202, and the arc-shaped piece 1204 is fixed to one end of the surface of the rotating shaft 1203;

[0021] The top of the arc-shaped piece 1204 is hinged with a connecting rod 10, the top of the connecting rod 10 is hinged with the bottom of the call button body 6, a columnar hinge head 9 is fixed to one side of the bottom of the call button body 6, the bottom of the columnar hinge head 9 and the top of the connecting rod 10 are hinged with each other, and the columnar hinge head 9 and the connecting rod 10 are both made of hard plastic material;

[0022] A tension spring monomer 1205 is installed on the outer wall of one side of the arc-shaped support arm 1201. The bottom end of the tension spring monomer 1205 and the bottom end of the arc-shaped piece 1204 are buckled with each other. When the call button body 6 is pressed, the push rod 8 contacts the contactor contact 7, thereby providing a contact signal to the PCB board 2 and the plug connector 3. In this process, the bottom end of the call button body 6 pushes the arc-shaped piece 1204 to swing through the connecting rod 10, and the rotating shaft 1203 serves to connect the two arc-shaped pieces 1204 on the same horizontal line. Because the bottom end of the connecting rod 10 and one end of the arc-shaped piece 1204 are hinged to each other, when the connecting rod 10 drives the arc-shaped piece 1204 to swing, the bottom end of the arc-shaped piece 1204 pulls the tension spring monomer 1205 to be in a stretched state;

[0023] When the call button body 6 is no longer pressed, the tension spring monomer 1205 forces the arc-shaped piece 1204 and the rotating shaft 1203 to reset, that is, the call button body 6 is pushed upward and reset. The rod-type elastic reset structure 12 is designed to be applicable to various models and specifications of elevator call buttons, so that it can be effectively used in different types of buildings and places;

[0024] A protective ring 11 is provided at one end of the cylindrical hollow shell 1, and an annular hollow portion 1101 for the connecting rod 10 to move is provided on one side of the protective ring 11. The protective ring 11 is used to separate the internal space of the cylindrical hollow shell 1, and the annular hollow portion 1101 serves as the action area for the connecting rod 10 to swing.

[0025] An annular lip 5 is fixed to one end of the surface of the upper support shell 4. The cross-sectional shape of the annular lip 5 is a right triangle. The annular lip 5 serves to decorate the upper support shell 4 and enables the upper support shell 4 to be embedded in the elevator control panel.

[0026] The rod-type anti-stuck structure is an annular flange 601 integrally formed at the edge of the bottom end of the call button body 6, and four guide columns 602 equidistantly installed at the bottom end of the annular flange 601. The bottom end of the guide column 602 extends to the interior of the upper support shell 4. The interior of the upper support shell 4 is provided with a columnar sinking cavity 101 for the guide column 602 to slide. The top of the call button body 6 is provided with a recessed portion extending downward. When the user presses the call button body 6, the guide column 602 at the bottom end of the call button body 6 slides in the columnar sinking cavity 101. The columnar sinking cavity 101 and the guide column 602 serve to guide the movement of the call button body 6, thereby reducing the probability of the call button body 6 getting stuck or malfunctioning and improving the reliability of the button.

[0027] When the embodiment of the present application is used, the staff first installs the call button on the elevator control panel. The elevator control panel is connected to the plug connector 3 through the signal connector. When the user presses the call button body 6, the call button body 6 transmits force to the contactor contact 7 through the rod-type elastic reset structure 12 and the push rod 8. At this time, the trigger circuit on the PCB board 2 is closed, and then the call signal is transmitted to the elevator control system, thereby realizing the call function of the elevator car. During the button reset process, four mirror-symmetrical rod-type elastic reset structures 12 provide a reset force for the call button body 6, which enables the call button body 6 to be quickly and reliably reset to the original state. When the user When the button is pressed, the rod-type elastic reset structure 12 stores energy, and then releases the energy when the button is released, pushing the call button body 6 back to its original position quickly, ensuring that the call button body 6 is quickly ready to accept the next operation after each use, so that the elevator can respond quickly after receiving the request, and the fast button reset means that the passenger will feel feedback immediately after pressing the button, and there is no need to wait for the button to reset slowly, thereby improving the user experience. At the same time, the design of the rod-type elastic reset structure 12 is more durable and can withstand more presses without losing elasticity, reducing the wear of the button assembly, extending the life of the button, and reducing the frequency of maintenance and replacement of parts.
