In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 4, fig. 1 is a schematic structural view illustrating an elevator handle according to an embodiment of the present invention, and fig. 4 is a schematic structural view illustrating an elevator handle according to an embodiment of the present invention mounted on a car. An elevator handrail provided by an embodiment of the invention comprises a handrail main body 10, a temperature acquisition device 20 and a prompt device 30. The handle body 10 is intended to be mounted in a car 90. The temperature acquisition device 20 is disposed on the armrest body 10 and is used for acquiring the current temperature of a human hand when the human hand holds the armrest body 10. The prompting device 30 is electrically connected to the temperature collecting device 20, and the prompting device 30 can receive the current hand temperature, obtain corresponding prompting information according to the current hand, and execute the prompting information.

In the above-mentioned elevator handrail, the temperature acquisition device 20 is provided in the handrail main body 10, and the temperature acquisition device 20 is electrically connected to the presentation device 30. When a passenger enters the car 90 and holds the handrail main body 10, the temperature acquisition device 20 acquires the current hand temperature and feeds the current hand temperature back to the prompting device 30. The prompting device 30 obtains corresponding prompting information according to the current hand temperature and executes the prompting information. So, the elevator handrail not only can satisfy and hold up basic demands such as leaning on, can also detect staff temperature, realizes man-machine interaction for the elevator handrail is more intelligent, promotes passenger's the experience of taking.

Specifically to in this embodiment, suggestion device is the voice broadcast device, like this when the passenger will hold at handrail main part 10, current staff temperature just can be gathered to temperature acquisition device 20, and feed back current staff temperature to the voice broadcast device, the voice broadcast device obtains corresponding voice prompt information according to current staff temperature, and broadcast this voice prompt information, report staff temperature, current weather temperature situation, the suggestion passenger notices information such as cold-proof, realize man-machine interaction, thereby promote passenger's the experience of taking.

In one embodiment, referring to fig. 1, the elevator handrail further includes a heating device 40, the handrail main body 10 is provided with a receiving cavity 11, and the heating device 40 is disposed in the receiving cavity 11 and is used for heating the handrail main body 10. Optionally, the heating device 40 is a resistance wire disposed along the length of the handrail body 10. In most cases, the elevator handrail is made of stainless steel or aluminum, and thus, when a passenger grips or leans on the elevator handrail in a cold area or in winter, the passenger feels a cold and uncomfortable feeling. In the present embodiment, the heating device 40 is disposed in the housing cavity 11 of the handrail main body 10, and the heating device 40 heats the housing cavity 11 to increase the temperature of the handrail main body 10, thereby reducing the uncomfortable feeling of passengers when riding in the elevator in cold weather areas or winter, and improving the comfort of riding in the elevator.

In one embodiment, referring to fig. 1 and 3, fig. 3 shows a block diagram of an operating circuit of the elevator handrail shown in fig. 1. The temperature acquisition device 20 is also used to acquire the current surface temperature of the armrest body 10. The elevator handrail further includes a constant temperature controller 60, the constant temperature controller 60 is electrically connected to the temperature collecting device 20 and the heating device 40, respectively, and the constant temperature controller 60 receives the current surface temperature of the handrail main body 10 and controls the input power of the heating device 40 according to the current surface temperature. When the elevator handrail is used, the heating device 40 is started to heat the handrail main body 10 by the heating device 40; meanwhile, the temperature collecting device 20 collects the current surface temperature of the armrest body 10 and feeds back the collected temperature signal to the thermostatic controller 60, and the thermostatic controller 60 controls the input power of the heating device 40. Specifically, if the current surface temperature is lower than the preset temperature value, the thermostatic controller 60 controls the input current to increase the heating power of the heating device 40; if the current surface temperature is higher than the preset temperature value, the thermostat controller 60 controls the input current to decrease the heating power of the heating device 40. Therefore, the surface temperature of the handrail main body 10 is stabilized at the preset temperature value, the phenomenon that the hands hold the handrail main body 10 to cause cold discomfort is avoided, and the comfort of taking an elevator is improved.

Specifically, the control temperature range of the thermostatic controller 60 is 30 to 50 ℃. Thus, the current surface temperature of the handrail main body 10 is in the temperature range of 30-50 ℃, so that the current surface temperature of the handrail main body 10 is closer to the constant temperature state of the human body, and the comfort of passengers using the elevator handrail is improved. Specifically in the present embodiment, the temperature controlled by the thermostat controller 60 is 37 ℃, so that the current surface temperature of the armrest body 10 is constant at 37 ℃.

Further, the presentation means 30 does not execute the presentation information for a certain time after the heating means 40 is activated. And/or when the temperature collected by the temperature collecting device 20 is changed linearly, the prompting device 30 does not execute the prompting message. It should be noted that, since the elevator handrail is provided with one temperature acquisition device 20, the temperature acquisition device 20 needs to acquire not only the current hand temperature of the hand held by the handrail main body 10, but also the current surface temperature of the handrail main body 10 in real time. Therefore, in the present embodiment, the prompting device 30 does not execute the prompting message within a certain time after the heating device 40 is started, i.e. during the process from the start of the heating device 40 to the reaching of the preset temperature value. In addition, after the heating device 40 heats the armrest body 10 to the preset temperature value, the temperature change of the armrest body 10 is generally in a linear relationship, and when a different person holds the armrest body 10, the temperature change collected by the temperature collection device 20 is generally irregular, so that when the temperature collected by the temperature collection device 20 is in a linear change, the prompt device 30 does not execute the prompt message. In this way, the prompting device 30 can be prevented from executing the prompting message according to the current surface temperature acquired by the temperature acquisition device 20.

Specifically, the predetermined time is 5min to 30 min. That is, the presentation device 30 does not execute the presentation information even if a person holds the armrest body 10 within 5min to 30min after the heating device 40 is activated. Specifically, in the present embodiment, the prompting device 30 does not execute the prompting message within 10min after the heating device 40 is started.

Optionally, both the first temperature acquisition device and the second temperature acquisition device measure temperature in a contact manner, for example, a liquid thermometer, a thermocouple, a photoelectric method, a thermochromatic method, and the like are used to acquire the current temperature of the human hand. The first temperature collecting device is disposed on the outer surface of the handrail main body 10, and may be fixed at a certain position of the handrail main body 10. The first temperature acquisition device is electrically connected with the prompting device 30 and is used for acquiring the current hand temperature of a hand held by the armrest main body 10. The first temperature acquisition device acquires the current hand temperature and feeds the current hand temperature back to the prompt device 30, and the prompt device 30 acquires corresponding prompt information according to the current hand temperature and executes the prompt information, such as broadcasting the hand temperature, the current weather and temperature condition, prompting passengers to pay attention to warmth and the like. The second temperature acquisition device is disposed on the inner wall of the armrest body, and the second temperature acquisition device is electrically connected to the thermostatic controller 60 and is configured to acquire the current surface temperature of the armrest body 10. The second temperature collecting means collects the current surface temperature of the armrest body 10 and feeds back the collected temperature signal to the thermostatic controller 60, and the thermostatic controller 60 controls the input power of the heating device 40.

The elevator handrail further comprises a heat-conducting flame-retardant body 50, and the heat-conducting flame-retardant body 50 is filled in the accommodating cavity 11. Alternatively, the heat conductive flame retardant 50 is an epoxy composite material, electronic silica gel, or the like. Specifically, the heat conductive and flame retardant material body covers the heating device 40 and is placed in the receiving cavity 11. Thus, the heat conductive flame retardant body 50 can not only rapidly conduct the heat generated by the heating device 40 to the surface of the handrail main body 10, but also achieve the purpose of flame retardance, avoid the combustion phenomenon caused by aging, damage, overlarge current and the like of the heating device 40, effectively avoid the occurrence of fire, and ensure the use safety of the elevator.

In one embodiment, referring to fig. 1 and 3, fig. 3 shows a block diagram of an operating circuit of an elevator handrail. The elevator handrail further includes a start controller 61, and the start controller 61 is electrically connected to the heating device 40. It will be appreciated that the start control functions as a master switch. When the handrail device is used, the starting controller 61 is started, and the starting controller 61 controls the heating device 40 to heat, so that the surface temperature of the handrail main body 10 is increased, and the discomfort of passengers when taking the elevator is reduced in cold weather areas or winter, and the comfort of taking the elevator is improved.

Further, referring to fig. 1 and 3, the elevator handrail further includes an input power source 70, and the input power source 70 is electrically connected to the temperature acquisition device 20, the prompting device 30, the thermostatic controller 60, and the start controller 61, respectively. In this way, the input power source 70 provides the required electric energy for the temperature acquisition device 20, the prompting device 30, the thermostatic controller 60 and the start controller 61, so as to ensure the normal operation of the temperature acquisition device 20, the prompting device 30, the thermostatic controller 60 and the start controller 61.

In one embodiment, referring to fig. 1 and 3, the elevator handrail further comprises a leakage protection device 80. When the earth leakage protection device 80 detects an electric leakage of the armrest body 10, the earth leakage protection device 80 interrupts the input power 70 or the circuit in which the heating device 40 is located. Alternatively, the earth leakage protection device 80 is an air switch or the like. When the electricity leakage occurs in the handrail of the elevator, the electricity leakage protection device 80 immediately cuts off the input power 70 or the circuit in which the heating device 40 is located, so that the current flowing into the handrail main body 10 is interrupted, thereby protecting the safety of passengers.

Specifically, referring to fig. 3, the prompting device 30 and the temperature collecting device 20 are connected in series in the same circuit and electrically connected to the input power source 70 to form an electrical circuit. Therefore, the prompting device 30 can obtain corresponding prompting information according to the current hand temperature and execute the prompting information, such as broadcasting the hand temperature, the current weather and temperature condition, prompting the passengers to pay attention to warm keeping and the like. The heating device 40, the starting controller 61, the thermostatic controller 60 and the earth leakage protection device 80 are connected in series in the same circuit and electrically connected with the input power supply 70, and the temperature acquisition device 40 is electrically connected with the thermostatic controller 60 to form another electric loop. Thus, the heating device 40 can heat the handrail main body 10, so that the surface temperature of the handrail main body 10 is stabilized at a preset temperature value, the discomfort of ice and cold caused by holding the handrail main body 10 by hands is avoided, and the comfort of taking an elevator is improved.
