[0002] A box elevator is a device installed in a building for vertical transportation of people or objects between floors. It is widely installed in high-rise buildings. The main body of a box elevator consists of a guide structure, a traction structure and a car, and cooperates with a control system and a safety system to achieve safe transportation of people and objects.

[0003] In order to ensure the safety of elevators when in use and to facilitate timely contact with the outside world in case of an emergency in the elevator, wireless calling devices are usually installed in elevators. The wireless calling devices for elevators in the prior art are usually integrated on the floor control panel in the elevator car, which is connected to the server through internal lines. In case of an emergency, the emergency call button can be pressed to call the backstage supervisor. In actual use, the alarm call button is integrated on the floor control panel, which is close to the floor button, causing passengers to easily press the alarm call button by mistake. In addition, due to the narrow space in the elevator, the emergency call button is directly exposed to the outside, making it easy for passengers to accidentally touch the emergency call button during body movements.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the alarm call button is installed on the back of the control panel, and the control panel is rotatably installed in the storage box through the rotation connection of the rotating shaft and the shaft sleeve. In an emergency, the passenger can turn over the control panel and press the alarm call button on the back to make an alarm call. Under normal circumstances, the alarm call button is hidden behind the control panel, which is not easy to be accidentally touched, which is conducive to ensuring the accuracy of alarm signal output and call, and can avoid the trouble caused by frequent accidental touches to the backstage supervisor. At the same time, by setting the control panel to a state that can rotate and swing, and using the first torsion spring for elastic support, the control panel can be swung to buffer and unload force after being impacted from the front, which is conducive to reducing the probability of internal components of the control panel being damaged by impact, and to a certain extent improves the safety and stability of the device during actual use, and is conducive to extending its service life;

[0019] 2. In the present invention, by setting the control panel to be able to flip and tilt backward, the device can be installed at a lower position in the elevator car. Adult passengers of normal height can gently push the control panel backward so that the floor buttons on the front are clearly displayed due to the tilt. Children with shorter height can easily touch the floor buttons on the device, so that the device can be stably used by different groups of people, which improves the convenience and comprehensiveness of the device in actual use to a certain extent;

[0020] 3. In the present invention, by setting the reset button on the back of the control panel, the passenger can actively press the reset button to cancel the alarm call when the alarm is triggered by mistake, which is conducive to further reducing the probability of stressful handling of relevant supervisors caused by the false alarm;

[0021] 4. In the present invention, by installing a rubber block corresponding to the alarm call button on the inner end wall of the back side of the storage box, in an emergency, the control panel is pushed back to the extreme position, and the alarm call can be triggered by pressing the alarm call button through the rubber block. At the same time, when multiple floor buttons are pressed chaotically at high frequency, or the control panel is swung at high frequency, it indicates that the device is in an abnormal use state, and the alarm call will be actively triggered. The device performs wireless call alarms in multiple ways, and the probability of false touch is low, which can effectively improve the convenience of the device in actual use;

[0022] 5. In the present invention, a first cam fixedly mounted on the left end of the rotating shaft is arranged in the first pump housing, and a second cam fixedly mounted on the right end of the rotating shaft is arranged in the second pump housing. During the reciprocating swing of the control panel, the first piston and the second piston are driven to move reciprocatingly with the help of the elastic support of the first spring and the second spring, so that the lubricating oil in the lubricating oil tank can be drawn and injected into the connecting position of the shaft sleeve and the rotating shaft, and the lubricating oil injected into the connecting position of the shaft sleeve and the rotating shaft can be drawn back into the lubricating oil tank, forming a state in which the lubricating oil circulates between the lubricating oil tank and the connecting position of the shaft sleeve and the rotating shaft. This can not only reduce the wear between the shaft sleeve and the rotating shaft during the swinging of the control panel, but also avoid the overflow of the lubricating oil at the connecting position of the shaft sleeve and the rotating shaft due to excessive injection, which is beneficial to ensure the long-term stable operation of the equipment.

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Embodiment: This embodiment provides a wireless calling device for remote monitoring of elevators, see Figure 1 - Fig.12 Specifically, it comprises a decorative panel 1, a storage box 101 which is recessed backward is fixedly installed in the middle of the decorative panel 1, a shaft sleeve 102 is fixedly installed at the lower position of the end wall of the storage box 101, a control panel 2 is installed in the storage box 101, and a plurality of evenly distributed floor buttons 201 are installed on the front of the control panel 2, an alarm call button 202 and an audio unit 203 are installed on the control panel 2, the alarm call button 202 is arranged on the back of the control panel 2, and a horizontal audio unit 203 is fixedly installed at the lower part of the inner part of the control panel 2. A rotating shaft 205 is set, and both ends of the rotating shaft 205 are rotatably inserted in the corresponding shaft sleeve 102, and the first torsion spring 206 is movably sleeved on the outer sides of the left and right ends of the rotating shaft 205, and one end of the first torsion spring 206 is fixedly connected to the rotating shaft 205, and the other end of the first torsion spring 206 is fixedly connected to the storage box 101, and the elastic supporting forces applied by the left and right first torsion springs 206 on the rotating shaft 205 are in opposite directions, and the control panel 2 is vertically set in the storage box 101 under the elastic support of the left and right first torsion springs 206.

[0047] When the device is installed and used, it is installed inside the elevator car. An antenna electrically connected to the inside of the control panel 2 is fixedly installed on the outside of the elevator car. A wireless data transceiver module is installed in the control panel 2. The stability of wireless data transmission by the wireless data transceiver module is guaranteed by the connection of the external antenna. A server corresponding to the device is set outside the elevator. Signals are transmitted between the server and the device through wireless data transmission. Wireless data transmission has high efficiency and high speed, and there is no need to consider long-distance wiring, which is conducive to improving the stability and convenience of the device in actual use.

[0048] During the use of the device, passengers in the elevator can control the rise and fall of the elevator car by pressing the corresponding floor button 201 to achieve normal use of the elevator. When an emergency occurs, the passenger can press the alarm call button 202 to send an alarm signal to the server through the device. After receiving the alarm signal, the server will send an alarm message to the relevant supervisor to remind the relevant personnel to take emergency measures. During this process, the device will call the relevant supervisor. Then the passenger can have a voice conversation with the supervisor through the audio unit 203 installed in the control panel 2, so that the external supervisor can timely understand the situation in the elevator. The audio unit 203 is integrated with a speaker and a microphone. A monitoring unit is installed in the elevator. When the device sends an alarm signal to the corresponding supervisor, the server will automatically project the picture collected by the monitoring unit onto the monitoring screen of the relevant supervisor, without the need for the supervisor to search, so that the supervisor can timely and accurately understand the actual situation in the elevator.

[0049] In the prior art, the alarm call button 202 is usually arranged on the front of the control panel 2. The alarm call button 202 is directly exposed on the outside. Although it is convenient for passengers to press it in an emergency, the alarm call button 202 directly exposed on the outside is easy to be touched by mistake during daily use, resulting in false triggering of the alarm signal. The frequent false touch of the alarm call button 202 will not only cause trouble to the relevant staff, but also easily affect the service life of the alarm call button 202, and even cause the relevant staff to be negligent in treating the real alarm signal, resulting in the alarm call button 202 failing to trigger the alarm signal in an emergency. The situation in which the relevant staff receives the signal but does not pay attention to it can easily lead to adverse consequences. The device in the present application sets the alarm call button 202 on the back of the flippable control panel 2. Under normal circumstances, the alarm call button 202 is hidden behind the control panel 2 and is not easily touched by mistake. When it is necessary to press the alarm call button 202 to make an emergency call, the passenger only needs to pull the alarm call button 202 forward to flip it forward. After flipping, the alarm call button 202 set on the back of the control panel 2 is exposed, and the passenger can press the alarm call button 202 to send an alarm signal and make a wireless call, which is conducive to ensuring the accuracy of the alarm signal output.

[0050] During the use of the device, passengers may hammer the control panel 2. When the front of the control panel 2 is subjected to an unexpected impact, the control panel 2 can swing backward in the storage box 101 due to the rotation of the rotating shaft 205 and the shaft sleeve 102. Under the action of the impact force, the impact force on the front of the control panel 2 is removed by the front and rear swing of the control panel 2 in the storage box 101 and the elastic support of the two left and right first torsion springs 206. When facing an impact, the probability of internal components of the control panel 2 being damaged by impact can be effectively reduced, which is beneficial to improving the safety and stability of the device during actual use and to a certain extent prolonging its service life.

[0051] The decorative panel 1 is fixedly installed in the middle and lower position of the elevator car. When the device is installed and used, since the control panel 2 can be flipped backwards and present a tilted state, even if the device is installed in a lower position in the elevator car, an adult of normal height can still press the floor button 201 on the control panel 2 conveniently and accurately. During use, the device is in the middle and lower position in the elevator car, and its installation position is lower than the installation position of the same type of device in a traditional car. When it is necessary to press the floor button 201, an adult passenger of normal height can first push the control panel 2 backwards slightly so that the front of the control panel 2 is tilted upward. At this time, the adult passenger can clearly and intuitively observe the position of each floor button 201 on the front of the control panel 2, and then accurately press the floor button 201. Similarly, since the device is installed at a lower position, passengers with shorter height, especially children, can easily touch the floor button 201 on the device, so that the device can be stably used by different groups of people, which improves the convenience of the device in actual use to a certain extent.

[0052] In the specific implementation process, Figure 8 As shown, the top inner end wall of the storage box 101 and the top outer end wall of the control panel 2 are arranged as mutually compatible arc structures, and the center of the arc structure coincides with the center of the rotating shaft 205. When the device is installed and used, by setting the top inner end wall of the storage box 101 to an arc structure that is compatible with the top inner end wall of the control panel 2, the width of the gap between the storage box 101 and the control panel 2 will not change during the backward swinging of the control panel 2, thereby avoiding the jamming of foreign objects due to the change in the gap width during the swinging of the control panel 2, which is beneficial to improve the stability and safety of the device in actual use to a certain extent.

[0053] In the specific implementation process, Figure 1 - Figure 3As shown, a handle 209 is fixedly installed on the upper front of the control panel 2, and the sound expansion holes of the audio unit 203 are opened on the three end walls of the front, top and back of the control panel 2. A reset button 204 is arranged on the back of the control panel 2, and the reset button 204 is used to cancel the alarm call. A touch screen 207 and a camera 208 are also installed on the back of the control panel 2. When many floor buttons 201 are pressed chaotically at a high frequency, an alarm call will be triggered. A gyroscope sensor is installed in the control panel 2, and an alarm call will be triggered when the gyroscope sensor detects that the control panel 2 swings at a high frequency. When the device is installed and used, the handle 209 is fixedly installed on the front of the control panel 2, so that the passenger can hold the handle 209 and pull it to drive the control panel 2 to flip to the front, providing a fulcrum for the passenger to flip open the back of the control panel 2, which is conducive to improving the convenience of use of the device.

[0054] During the use of the device, by opening the sound expansion holes corresponding to the audio unit 203 on the front, top and back surfaces of the control panel 2, it is beneficial to improve the clarity and stability of the audio interaction with the help of the audio unit 203 in various states of the device, and it is beneficial to ensure the clarity of emergency call interaction. At the same time, by setting the reset button 204 on the back of the control panel 2, when the passenger accidentally triggers the alarm, before the call is connected, the passenger can actively press the reset button 204 to cancel the alarm and call. The alarm will not be deleted, but will be recorded in the server in the form of a log, and the server will freeze the picture in the elevator car at that time and send it to the relevant supervisor. Under the condition of ensuring the safety of the passengers, the probability of the relevant supervisor responding to the stress caused by the accidental triggering of the alarm can be further reduced.

[0055] During the use of the device, alarm signals can be sent and wireless calls can be made in multiple ways. Taking into account the disorderly operations of some passengers in emergency situations, if multiple floor buttons 201 are pressed chaotically at high frequency during the operation of the device, it indicates that the passenger who actually presses the floor button 201 may be in a state of anxiety and out of control. At this time, there may be an emergency in the elevator car. The server will send an alarm signal to the relevant supervisor and actively trigger the wireless call function to facilitate the supervisor to understand the situation in the elevator car in a timely manner. Similarly, the gyroscope sensor installed in the control panel 2 can detect the status of the control panel 2. When the control panel 2 is swung back and forth at a high frequency, it indicates that it is in an abnormal use state. At this time, the server will also send an alarm signal to the relevant supervisor and make a wireless call. When the control panel 2 is flipped to the front, the passenger can make a video call with the relevant supervisor through the touch display 207 and the camera 208.

[0056] In the specific implementation process, Fig.10As shown, a rubber block 103 corresponding to the alarm call button 202 is fixedly installed on the back end wall of the storage box 101. When the device is installed and used, when a passenger needs to use the device to make a wireless call, the passenger can also push the control panel 2 backwards to make the control panel 2 flip backwards to the extreme position. At this time, the rubber block 103 fixedly installed on the back end wall of the storage box 101 will squeeze the alarm call button 202, send an alarm and make a wireless call. Since the control panel 2 has a certain travel when it swings backwards to the state where the alarm call button 202 is touched by the rubber block 103, the probability of mis-touch of the wireless call triggered in this way is low. The device is set with multiple ways to trigger the wireless call function, and the probability of mis-touch is low, which is conducive to ensuring the accuracy of alarm reminders and wireless calls in emergency situations. Various ways of triggering alarms and calls are posted on the front of the decorative panel 1.

[0057] In the specific implementation process, Figure 8 and Fig.12 As shown, a first notch 104 is provided at the position where the bottom of the storage box 101 and the decorative plate 1 are connected, and a second notch 3 is provided vertically at the lower part of the front of the control panel 2, and a cover plate 301 is vertically provided in the second notch 3, and the upper end of the cover plate 301 is hinged to the upper part of the inner part of the second notch 3, and a second torsion spring 302 is installed at the hinge position. When the device is installed and used, the first notch 104 is provided at the connection position between the bottom of the storage box 101 and the decorative plate 1, and the second notch 3 is provided at the lower part of the front of the control panel 2, so that the tilt angle of the control panel 2 to flip toward the lower part of the front can be increased, so that the back of the control panel 2 is turned over to present a tilt angle. The cover 301 is now in an upward tilted state, which makes it easier for passengers to make video calls with relevant personnel through the touch display 207 and the camera 208 in an emergency. The cover 301 is rotated and installed in the second slot 3, and with the elastic support of the second torsion spring 302, the cover 301 is kept flipped into the second slot 3. During the swinging of the control panel 2, the cover 301 can block and cover the first slot 104 and the second slot 3. Under normal circumstances, the front of the decorative panel 1, the control panel 2 and the cover 301 are flush, and the cover 301 can decoratively cover the first slot 104 and the second slot 3, which is beneficial to ensuring the overall aesthetics of the front of the device.

[0058] In the specific implementation process, Figure 5 - Figure 7 , Fig. 9 and Fig.11As shown, a lubricating oil tank 4 is fixedly installed on the back of the storage box 101, and the filling port of the lubricating oil tank 4 is arranged on the inner end wall of the back of the storage box 101, an oil delivery channel 401 is opened on the inner central axis of the rotating shaft 205, and an oil filling hole 402 arranged on the inner side of the shaft sleeve 102 is opened around the outer end wall of the rotating shaft 205, and the oil filling hole 402 is communicated with the oil delivery channel 401, and a first pump housing 5 movably sleeved on the outer side of the left end of the rotating shaft 205 is fixedly installed on the back of the decorative plate 1, and a first piston 501 is slidably installed in the first pump housing 5, and the first A first spring 502 for elastically supporting the first piston 501 is fixedly installed on the side of the pump housing 5 away from the rotating shaft 205, and a first oil inlet pipe 503 and a first oil outlet pipe 504 are fixedly connected to the side of the first pump housing 5 away from the rotating shaft 205. The first oil inlet pipe 503 is fixedly connected to the bottom of the lubricating oil tank 4, and the first oil outlet pipe 504 is rotatably connected to the left end of the oil delivery channel 401. Check valves are installed in the first oil inlet pipe 503 and the first oil outlet pipe 504, and a first cam 8 arranged in the first pump housing 5 is fixedly installed on the left end of the rotating shaft 205.

[0059] When the device is installed and used, lubricating oil is injected into the lubricating oil tank 4, the one-way valve in the first oil inlet pipe 503 restricts the lubricating oil therein to flow only to the first pump housing 5, and the one-way valve in the first oil outlet pipe 504 restricts the lubricating oil to flow only to the oil delivery channel 401. When the control panel 2 is pushed, the first cam 8 installed in the first pump housing 5 is driven to rotate by means of the rotation of the rotating shaft 205. During the rotation of the first cam 8, the first piston 501 installed in the first pump housing 5 is squeezed, so that the first piston 501 moves in the first pump housing 5, compressing the space in the first pump housing 5, and the lubricating oil originally stored in the first pump housing 5 enters the oil delivery channel 401 through the first oil outlet pipe 504, and then in the oil delivery channel 401, the lubricating oil in the oil delivery channel 401 is filled with liquid. During transmission, the oil is squeezed into the rotating connection between the sleeve 102 and the rotating shaft 205 through the oil filling hole 402 to perform lubrication operation. When the control panel 2 is reset, the first cam 8 is driven to reset synchronously, and the squeezing of the first piston 501 is lost. Under the elastic support of the first spring 502, the first piston 501 is gradually reset, so that the space for storing lubricating oil in the first pump housing 5 is gradually increased. At this time, the lubricating oil stored in the lubricating oil tank 4 enters the first pump housing 5 through the first oil inlet pipe 503 for temporary storage. During the reciprocating swing of the control panel 2, the above operation is continued, and the lubricating oil is automatically replenished at the rotating connection between the sleeve 102 and the rotating shaft 205 to ensure the stability and smoothness of the control panel 2 during the swinging process.

[0060] The lubricating oil tank 4 is fixedly mounted on the back of the storage box 101, and the filling port on the lubricating oil tank 4 is set on the inner end wall of the back of the storage box 101, so that the staff can directly expose the filling port after flipping the control panel 2 forward, which is conducive to improving the convenience of the staff to regularly fill the lubricating oil into the lubricating oil tank 4.

[0061] In the specific implementation process, Figure 4 - Figure 6 As shown, an oil extraction hole 6 is opened inside the sleeve 102, and a second pump housing 7 movably sleeved on the outer side of the right end of the rotating shaft 205 is fixedly installed on the back side of the decorative panel 1, and a second piston 701 is slidably installed in the second pump housing 7, and a second spring 702 for elastically supporting the second piston 701 is fixedly installed on the side of the second pump housing 7 away from the rotating shaft 205, and a second oil inlet pipe 703 and a second oil outlet pipe 704 are fixedly connected to the side of the second pump housing 7 away from the rotating shaft 205, the second oil inlet pipe 703 is connected to the oil extraction hole 6, and the second oil outlet pipe 704 is connected to the lubricating oil tank 4, and one-way valves are installed in the second oil inlet pipe 703 and the second oil outlet pipe 704, and a second cam 801 arranged in the second pump housing 7 is fixedly installed on the right end of the rotating shaft 205.

[0062] When the device is installed and used, the one-way valve in the second oil inlet pipe 703 restricts the lubricating oil therein to flow only to the second pump housing 7, and the one-way valve in the second oil outlet pipe 704 restricts the lubricating oil therein to flow only to the lubricating oil tank 4. In the process of the control panel 2 being pushed, the second cam 801 arranged in the second pump housing 7 rotates with the help of the rotating shaft 205, and applies an extruding force to the second piston 701 in the second pump housing 7, so that the second piston 701 moves in the second pump housing 7, compressing the space for storing lubricating oil in the second pump housing 7, and squeezing the lubricating oil stored in the second pump housing 7 into the lubricating oil tank 4 through the second oil outlet pipe 704. When the control panel 2 is swung During the resetting process, driven by the rotating shaft 205, the second cam 801 is reset synchronously and loses the squeezing of the second piston 701. At this time, under the elastic support of the second spring 702, the second piston 701 is pushed to reset, and the space for storing lubricating oil in the second pump housing 7 gradually increases. Under the suction action, the lubricating oil fed into the rotating connection position of the sleeve 102 and the rotating shaft 205 enters the second pump housing 7 through the oil extraction hole 6 for temporary storage, and is fed into the lubricating oil tank 4 during the next swinging of the control panel 2, so as to avoid the automatic filling of the lubricating oil causing the lubricating oil to overflow from the sleeve 102 and the rotating shaft 205, which is beneficial to ensure the stability of the device during actual use.

[0063] Specifically, the working principle and operation method of the present invention are as follows:

[0064] The alarm call button 202 is installed on the back of the control panel 2. The alarm call button 202 can be exposed by flipping the control panel 2, so as to avoid the alarm call button 202 being frequently accidentally touched and causing adverse consequences under normal circumstances. Since the control panel 2 is rotatably installed in the storage box 101 through the rotating shaft 205, the control panel 2 can be flipped and tilted backward, so that the device can be installed at a lower position in the elevator car, which is convenient for different groups of people to use. By setting the control panel 2 to a flippable state and elastically supporting it with the help of the first torsion spring 206, the front of the device can be buffered when it is subjected to violent impact, thereby extending the service life of the device. The reset button 204 is installed on the back of the control panel 2 and can be used to cancel the accidental call. When the floor button 201 is pressed chaotically and frequently, or when the control panel 2 is swung at a high frequency, an alarm call can be triggered, and the control panel 2 is pushed backward to The limit is reached, so that the rubber block 103 presses the alarm call button 202, which can also trigger the alarm call. In the process of pushing the control panel 2, the first cam 8 in the left first pump housing 5 rotates, and cooperates with the first spring 502 to drive the first piston 501 to move back and forth, and draws the lubricating oil in the lubricating oil tank 4 into the connection position between the sleeve 102 and the rotating shaft 205. At the same time, the second cam 801 in the right second pump housing 7 rotates, and cooperates with the second spring 702 to drive the second piston 701 to move back and forth, and the lubricating oil injected into the connection position between the sleeve 102 and the rotating shaft 205 is drawn back into the lubricating oil tank 4, forming a state in which the lubricating oil circulates at the connection position between the lubricating oil tank 4 and the sleeve 102 and the rotating shaft 205. This can not only reduce the wear between the sleeve 102 and the rotating shaft 205 during the swinging of the control panel 2, but also avoid excessive injection of lubricating oil and overflow at the connection position between the sleeve 102 and the rotating shaft 205.

[0065] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
