Description

Technical Field

[0001] The utility model belongs to the technical field of temperature detection and relates to a non-contact body temperature detection device for automobiles. Background Art

[0002] Increased body temperature is a typical symptom of some serious infectious diseases. In order to prevent it from spreading among the crowd, it is necessary to set up temperature detection devices in public places such as buses, stations, and light rail stations to detect and isolate as soon as possible. Among them, the method adopted by buses is to equip passengers with specialized temperature detectors to detect the body temperature of passengers. This method consumes huge human and material resources, and the bus is crowded with people. The temperature detector will come into contact with different passengers, which has a certain risk of infection. At the same time, the bus stops are located outdoors. If the existing non-contact automatic body temperature detection device is set at each outdoor stop, it will cost a lot of money, and the device is easily polluted by the external environment, such as corrosion by dust and stains, aging caused by sunlight, etc. If the existing non-contact automatic body temperature detection device similar to that used in railway stations is placed in the bus, the device is relatively large in size, will take up more space in the bus, and is not conducive to placement.

[0003] Existing non-contact automatic temperature detection devices usually choose the forehead as the detection site. The forehead skin is relatively thin, and the temperature tested on the forehead will be closer to the human body temperature. However, the skin temperature of the forehead exposed to the outside is not stable, especially in summer and winter, there is a large temperature difference between the forehead temperature and the human body temperature, and the detection data error is large. The human wrist is insulated by clothing and is less affected by the external environment temperature. At the same time, the temperature of the wrist itself is relatively stable. During the awake time, the fluctuation range of the wrist temperature is about 1°C, which is much smaller than the fluctuation of the forehead exposed to the wind and sun. Utility Model Content

[0004] The utility model aims to provide a non-contact body temperature detection device for automobiles, which reduces the space occupied in the automobile, realizes non-contact detection of body temperature at the wrist of a human body, and improves the accuracy of body temperature detection.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is: a non-contact body temperature detection device for automobiles, comprising a pedal and a support tube located on one side of the pedal, an inflation mechanism is provided under the pedal, the inflation end of the inflation mechanism is in contact with the bottom of the pedal, the bottom of the support tube is sealed and connected to the gas expansion end of the inflation mechanism, the top of the support tube is open, and a sliding rod is sealed and slidably connected inside the support tube, an infrared temperature measurement component is provided on the top of the sliding rod, when the pedal squeezes the inflation mechanism, the inflation mechanism fills gas into the support tube, and the sliding rod drives the infrared temperature measurement component to rise.

[0006] The working principle and beneficial effect of this basic scheme are as follows: during detection, a person stands on the pedal, and the inflatable mechanism is located below the pedal, and the inflatable end of the inflatable mechanism contacts the bottom of the pedal. Then, the person applies pressure to the inflatable end of the inflatable mechanism through the pedal to squeeze the inflatable mechanism. At the same time, the gas expansion end of the inflatable mechanism is connected to the bottom of the support tube, so that the pedal squeezes the inflatable mechanism and the inflatable mechanism is inflated into the support tube. The sliding rod is sealed and slidably connected to the support tube, so that the bottom of the sliding rod and the inner cavity of the support tube are closed spaces, ensuring that the gas filled into the bottom of the support tube and the sliding rod by the inflatable mechanism will not leak to the outside of the support tube. The gas at the bottom of the support tube increases, and the increased gas in the support tube exerts an upward force on the sliding rod, so that the sliding rod slides upward to approach the wrist of the person standing on the pedal. The infrared temperature measurement component at the top of the sliding rod moves up with the sliding rod and approaches the wrist of the human body, realizing non-contact detection of the human wrist. When the device is not needed, the sliding rod is retracted into the support tube, reducing the space occupied by the device and making it more convenient to place the device.

[0007] Furthermore, a base is provided under the pedal, a support spring is provided between the bottom of the pedal and the top of the base, the side of the pedal away from the support spring is hinged to the base, one end of the support spring is fixedly connected to the top of the base, and the other end of the support spring is fixedly connected to the bottom of the pedal, a groove is provided on the top of the base, and the inflation mechanism is placed in the groove.

[0008] One side of the pedal is hinged to the base, and the other side is connected to the base with a support spring, so that the pedal is tilted, and the side of the pedal connected to the support spring is tilted upward, which increases the space between the pedal and the base, which is convenient for placing the inflatable mechanism. At the same time, the side of the pedal hinged to the base is located at a lower horizontal plane, which is convenient for people to step on the pedal from the lower side, making it easy to use. The support spring can ensure the smooth reset of the pedal, and at the same time, it buffers the pedal to prevent the inflatable mechanism from being damaged by the pedal being pressed down too far or too fast.

[0009] Furthermore, an automatic disinfection mechanism for disinfecting the sliding rod and the infrared temperature measurement component is provided in the support tube.

[0010] When the sliding rod drives the infrared temperature measuring component to extend out of the supporting tube, the sliding rod and the infrared temperature measuring component are exposed to the external environment and may be contaminated with bacteria and viruses in the external environment, or in the process of detecting body temperature, they may accidentally come into contact with the limbs of the person to be tested and be contaminated with bacteria. The automatic disinfection mechanism can automatically disinfect the sliding rod and the infrared temperature measuring component to prevent the sliding rod and the infrared temperature measuring component from carrying viruses and increasing the chance of infection, thereby enhancing safety of use.

[0011] Furthermore, the automatic disinfection mechanism includes an annular groove, an ultraviolet lamp, a sliding switch and a door panel. The annular groove is arranged on the inner wall of the support tube close to the opening side, the ultraviolet lamp is placed in the annular groove, the ultraviolet lamp is connected to a power supply through a sliding switch, the sliding switch is located on the inner wall of the support tube, the sliding switch is connected to a control mechanism that controls its automatic sliding, and the door panel is located at the opening of the support tube, and the door panel is hinged to the support tube.

[0012] The ultraviolet lamp is placed in the ring groove so that the light of the ultraviolet lamp can diffuse in the ring groove, thereby increasing the irradiation range of the ultraviolet lamp and enhancing the disinfection effect. The control mechanism controls the sliding switch to slide open and closed. When the slide bar slides outward from the support tube, the control mechanism controls the sliding switch to be in the disconnected state, thereby turning off the ultraviolet lamp. Compared with the ultraviolet lamp being always in the on state, unnecessary energy consumption is reduced. When the slide bar slides into the support tube, the control mechanism controls the sliding switch to connect, and the ultraviolet lamp is turned on to disinfect the slide bar and the infrared temperature measurement component. At the same time, when the slide bar moves outward from the support tube, the door panel can be pushed outward, and when the slide bar is reset into the support tube, the door panel rotates downward due to its own gravity to close the opening of the support tube, thereby preventing a large amount of light from the ultraviolet lamp from entering the external environment and generating radiation.

[0013] Furthermore, the control mechanism includes a groove on the sliding part of the sliding switch, a placement groove arranged on the sliding rod and a card block placed in the placement groove. The side of the sliding part on the sliding switch close to the sliding rod is tangent to the inner wall of the support tube. A connecting spring is provided between the card block and the placement groove, and the card block can extend out of the placement groove and engage with the groove.

[0014] When the slide bar moves outward from the support tube, the card block moves synchronously with the slide bar. When the card block does not overlap with the groove, the card block is squeezed by the inner wall of the support tube and completely retracts into the placement groove. When the card block overlaps with the groove, the card block is extended into the groove by the action of the connecting spring. At this time, the card block still moves with the slide bar, and the card block drives the sliding part of the sliding switch to move synchronously until the groove moves to the edge of the connection between the sliding switch and the inner wall of the support tube. The card block is blocked by the inner wall of the support tube and escapes from the groove, and retracts into the placement groove again and moves with the slide bar. When the slide bar is reset, similarly, the card block can drive the sliding part of the sliding switch downward.

[0015] Furthermore, the two side surfaces of the block opposite to the moving direction of the slide bar are inclined from the side close to the placement groove toward the side close to the inner wall of the support tube and toward the opposite surface.

[0016] When the card block is blocked by the inner wall of the support tube and escapes from the groove, the inner wall of the support tube applies a force to the inclined surface of the card block to make the card block retract into the placement groove. Compared with the ordinary plane, the surface contact is changed into point-to-surface contact, which reduces the friction between the card block and the support tube, is more conducive to the resetting of the card block, and also reduces the friction loss between the card block and the support tube.

[0017] Furthermore, the infrared temperature measurement component is connected to a power source via a switch device.

[0018] The switch device can control the opening and closing of the infrared temperature measuring component, thereby achieving more flexible control of the infrared temperature measuring component.

[0019] Furthermore, the switch device adopts a reset switch button, and the reset switch button is fixedly connected to the inflation mechanism or the pedal and is located at a contact position between the inflation mechanism and the bottom of the pedal.

[0020] The reset switch button is set on the inflation mechanism or the pedal. When the pedal squeezes the inflation mechanism, the reset switch button is linked without the need for additional control components. When the pedal does not squeeze the inflation mechanism, the reset switch button can be automatically reset without manual control, and the operation is simple.

[0021] Furthermore, a positioning groove is provided on the upper surface of the pedal.

[0022] The positioning groove can limit the stepping position of the subject on the pedal, which is beneficial to control the relative position between the support tube and the pedal, and indirectly control the position relationship between the slide bar and the wrist of the subject when the slide bar extends from the support tube.

[0028] As attached Figure 1 As shown: The utility model discloses a non-contact body temperature detection device for automobiles, comprising a pedal 1 and a support tube 4 located at one side of the pedal 1, the pedal 1 is placed horizontally, and the support tube 4 is placed vertically.

[0029] The upper surface of the pedal 1 is provided with a positioning groove, and the positioning groove is set in the shape of a footprint. A base 2 is provided below the pedal 1, and a support spring 6 is provided between the bottom of the pedal 1 and the top of the base 2. The end of the pedal 1 away from the support spring 6 is hinged to the edge of the base 2, one end of the support spring 6 is welded to the top of the base 2, and the other end of the support spring 6 is welded to the bottom of the pedal 1. The end of the pedal 1 away from the hinge is tilted upward by the support spring 6, and the pedal 1 is in an inclined state. A groove is provided on the top of the base 2, and it is preferred that the side of the groove away from the hinge between the base 2 and the pedal 1 is set as an opening to increase the area of ​​the groove. An inflation mechanism 3 is placed in the groove, and the inflation mechanism 3 can preferably be an air bag, an air pump or a piston cylinder 13. The inflation end of the inflation mechanism 3 touches the bottom of the pedal 1, such as the top of the push rod of the air pump touches the bottom of the pedal 1. In this embodiment, a piston cylinder 13 is preferably used as the inflation mechanism 3, and a piston plate 14 is provided in the piston cylinder 13. A vertical piston rod 15 is welded to the upper surface of the piston plate 14, and the top end of the piston rod 15 touches the bottom of the pedal 1. A gas expansion end is provided at the bottom of the piston cylinder 13 as a gas exhaust port.

[0030] The support tube 4 is located at the adjacent side of the hinge between the pedal 1 and the base 2. The bottom of the support tube 4 is sealed and connected to the gas expansion end of the inflation mechanism 3 through the air pipe, and the top of the support tube 4 is open. A slide bar 5 is sealed and slidably connected in the support tube 4. At the same time, according to the gas capacity that the inflation mechanism 3 can provide, the length of the support tube 4 and the length of the accommodation space for the slide bar 5 in the support tube 4 are adjusted, so as to ensure that the gas discharged from the inflation mechanism 3 can make the slide bar 5 extend out of the support tube 4 by a certain length and close to the wrist of the person to be tested.

[0031] In this embodiment, an infrared temperature measuring component 7 is provided on the top of the slide bar 5. The infrared temperature measuring component 7 includes an infrared sensor (such as 10TO583T, etc.) and a display. The infrared sensor is welded, bonded, or riveted to the top of the slide bar 5. The display is arranged on the side of the support tube 4 and positioned by an additional bracket (not shown in the drawings). The display can be welded to the bracket or directly placed on the bracket. The output end of the infrared sensor is electrically connected to the input end of the display. The display is provided with an A / D converter to convert the voltage signal measured by the infrared sensor into a numerical signal. The infrared temperature measuring component 7 is connected to a power supply through a switching device, and the switching device adopts a reset switch button (such as reset switch M3SS7-42G-20 or CX-C007, etc.). The reset switch button is fixedly connected (welded or bonded, etc.) on the inflation mechanism 3 or the pedal 1, and is located at a position where the inflation mechanism 3 touches the bottom of the pedal 1. The top end of the piston rod 15 of the above-mentioned inflation mechanism 3 is an arc-shaped surface that fits the end face of the reset switch button, so that the inflation mechanism 3, the reset switch button and the pedal 1 are more tightly connected when they are against each other.

[0032] An automatic disinfection mechanism for disinfecting the slide bar 5 and the infrared temperature measuring assembly 7 is provided in the support tube 4, and the top of the slide bar 5 can be retracted into the support tube 4. The automatic disinfection mechanism includes an annular groove 8, an ultraviolet lamp 9, a sliding switch 10 and a door panel 12. The annular groove 8 is provided on the inner wall of the support tube 4 near the opening side, and the notch of the annular groove 8 is preferably facing the inside of the support tube 4. When the slide bar 5 is retracted in the support tube 4, the ultraviolet lamp 9 provided on the slide bar 5 is placed in the annular groove 8, and one or more ultraviolet lamps 9 can be provided. The ultraviolet lamp 9 is connected to a power supply through the sliding switch 10, and the sliding switch 10 is located on the inner wall of the support tube 4. The sliding switch 10 is connected to a control mechanism for controlling its automatic sliding. The sliding switch 10 can be modified with a conventional sliding switch 10 on the market such as SS26D02. The door panel 12 is located at the opening of the support tube 4, and the door panel 12 is hinged to the support tube 4.

[0033] The control mechanism includes a groove on the sliding member of the sliding switch 10, a placement groove provided on the sliding rod 5, and a block 11 placed in the placement groove. The side of the sliding member on the sliding switch 10 close to the sliding rod 5 is tangent to the inner wall of the support tube 4. A connecting spring is provided between the block 11 and the placement groove. The block 11 can extend out of the placement groove and engage with the groove. The two side surfaces of the block 11 opposite to the moving direction of the sliding rod 5 are inclined from the side close to the placement groove to the side close to the inner wall of the support tube 4 and toward the opposite side.

[0034] Specific operation process:

[0035] Detection process: During the detection, a person stands on the pedal 1, and the pedal 1 is pressed down by the person's own weight, and the pedal 1 rotates downward around the hinge between the pedal 1 and the base 2. The pedal 1 moves downward to squeeze the inflation end of the inflation mechanism 3, and squeezes the gas in the inflation mechanism 3 into the bottom of the support tube 4. The slide bar 5 is sealed and slidably connected with the support tube 4. The gas at the bottom of the support tube increases, and the increased gas pushes the slide bar 5 upward. The upward movement of the slide bar 5 drives the infrared sensor on the slide bar 5 to approach the wrist of the person standing on the pedal 1, until the pedal 1 is balanced and no longer moves downward. At this time, the squeezed gas in the inflation mechanism 3 completely enters the support tube 4, and the slide bar 5 is pushed to the measurement position by the gas in the support tube 4 and remains stable, realizing non-contact detection of the human wrist.

[0036] When the slide bar 5 moves outward from the support tube 4, the block 11 moves synchronously with the slide bar 5. When the block 11 moves to coincide with the groove, the block 11 is no longer squeezed by the inner wall of the support tube 4, and is thus extended into the groove of the sliding part of the sliding switch 10 by the action of the connecting spring. At this time, the block 11 still moves with the slide bar 5, and the block 11 drives the sliding part of the sliding switch 10 to move synchronously until the groove moves to the edge of the connection between the sliding switch 10 and the inner wall of the support tube 4. The block 11 is blocked by the inner wall of the support tube 4 and escapes from the groove, and retracts into the placement groove and moves with the slide bar 5. At this time, the sliding switch 10 is in a connected state, so that the infrared temperature measurement component 7 is connected to the power supply and enters the open state. When the slide bar 5 is reset, similarly, the block 11 can drive the sliding part of the sliding switch 10 downward.

[0037] Disinfection process: The ultraviolet lamp 9 is placed in the annular groove 8, so that the light of the ultraviolet lamp 9 can diffuse in the annular groove 8, increase the irradiation range of the ultraviolet lamp 9, and enhance the disinfection effect. The control mechanism controls the sliding switch 10 to slide open and close. When the slide bar 5 slides outward from the support tube 4, the control mechanism controls the sliding switch 10 to be in the disconnected state, so that the ultraviolet lamp 9 is in the closed state. Compared with the ultraviolet lamp 9 being always in the on state, unnecessary power consumption is reduced. When the slide bar 5 slides into the support tube 4, the control mechanism controls the sliding switch 10 to connect, and the ultraviolet lamp 9 is turned on to disinfect the slide bar 5 and the infrared temperature measurement component 7. At the same time, when the slide bar 5 moves outward from the support tube 4, the door panel 12 can be pushed outward, and when the slide bar 5 is reset into the support tube 4, the door panel 12 is rotated downward by its own gravity to close the opening of the support tube 4, so as to prevent the light of the ultraviolet lamp 9 from irradiating into the external environment and generating radiation.
