For example, the "connection" can be a fixed connection, a detachable connection, or an integrated setting; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the technical field of the present utility model, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.
[0056] The utility model provides an aging test device, which is suitable for the application scenario of performing aging test on an electric bed. The utility model can perform a mechanized aging test on the electric bed so as to improve accuracy and reduce labor costs.
[0057] like Figure 2 As shown, the electric bed 1 includes a bed frame 101, a fixed portion 1021 fixed on the bed frame 101, a movable portion 1022 hingedly connected to the fixed portion 1021, and a power unit 103 for driving the movable portion 1022 to move closer to or away from the bed frame 101.
[0058] The aging test equipment includes a magnetic induction component 2, a magnet 3, and a digital display counter 4. The magnetic induction component 2 is mounted on the bed frame 101; the magnet 3 is mounted on the movable part 1022, and moves closer to or farther from the magnetic induction component 2 as the movable part 1022 moves; the digital display counter 4 is electrically connected to the magnetic induction component 2, and is used to display the number of times the magnetic induction component 2 senses the magnet 3.
[0059] The aging test equipment provided in this embodiment, when it is necessary to perform an aging test on the electric bed 1, first install the magnetic induction component 2 on the bed frame 101 and install the magnet 3 on the movable part 1022; then, start the power unit 103 to drive the movable part 1022 to approach or move away from the bed frame 101; whenever the movable part 1022 moves downward until the magnet 3 approaches the magnetic induction component 2, the magnetic induction component 2 generates an electrical signal under the action of the magnetic field of the magnet 3, and the digital display counter 4 counts once after receiving the electrical signal. Therefore, the current number of movements of the movable part 1022 can be known by simply observing the value displayed on the digital display counter 4.
[0060] If the current number of times exceeds the design life, the electric bed 1 is considered to have passed the aging test; if the movable part 1022 moves abnormally before reaching the design life, the electric bed 1 is considered to have failed the aging test.
[0061] Therefore, the aging test equipment provided by the present invention can perform a mechanized aging test on the electric bed 1, thereby improving accuracy and reducing labor costs.
[0062] In this embodiment, the backs of the magnetic induction component 2 and the magnet 3 are both provided with Velcro hook surfaces.
[0063] Both the bed frame 101 and the movable part 1022 are provided with Velcro fur surfaces that are detachably connected to the corresponding Velcro hook surfaces. When the electric bed 1 needs to be subjected to an aging test, one Velcro hook surface is pasted and fixed on the magnetic sensing component 2, and one Velcro fur surface is pasted and fixed on the bed frame 101, and then the Velcro hook surface on the back of the magnetic sensing component 2 can be connected to the Velcro fur surface of the bed frame 101, thereby completing the installation and fixing operation between the magnetic sensing component 2 and the bed frame 101. Another Velcro hook surface is pasted and fixed on the magnet 3, and another Velcro fur surface is pasted and fixed on the movable part 1022, and then the Velcro hook surface on the back of the magnet 3 can be connected to the Velcro fur surface of the movable part 1022, thereby completing the installation and fixing operation between the magnet 3 and the movable part 1022.
[0064] After the test is completed, the magnetic induction component 2 and the magnet 3 are removed, and then the Velcro on the bed frame 101 and the movable part 1022 is torn off, which is simple and convenient. It should be noted that the Velcro hook surface on the back of the magnetic induction component 2 and the magnet 3 can be reused for the next aging test, so there is no need to tear it off.
[0065] In some other embodiments, adhesive can be directly provided on the back of the magnetic induction component 2 and the magnet 3, and the magnetic induction component 2 and the magnet 3 can be fixed on the electric bed 1 by gluing.
[0066] Optionally, the aging test equipment further includes an alarm device 5, which is electrically connected to the digital display counter 4 and is used to send sound and / or light warning information. For example, the alarm device 5 includes a buzzer and / or a flash light.
[0067] Exemplarily, the buzzer is used to play the first sound warning information or the second sound warning information, and the flash light is used to send the first light warning information or the second light warning information.
[0068] If the current number of times displayed by the digital counter 4 has reached the design life, the alarm device 5 can broadcast a first sound warning message and / or a first light warning message (for example, the first sound warning message is a short beeping sound, and the first light warning message is a constant green light) to remind the tester that the test is completed and the test result is qualified;
[0069] If the movable portion 1022 exhibits abnormal movement before reaching its design life, the alarm device 5 may broadcast a second sound warning message and / or emit a second light warning message (for example, the second sound warning message is a long beeping sound, and the second light warning message is a flashing red light) to remind the tester that the electric bed 1 has failed the aging test.
[0070] In this embodiment, the aging test equipment further includes a timer, which is electrically connected to the magnetic sensing component 2 and is used to obtain the time interval for the magnetic sensing component 2 to sense the magnet 3 .
[0071] If there is no abnormal movement of the movable part 1022, the time for the movable part 1022 to reciprocate once is roughly equal, for example, 2s~3s; if there is abnormal movement of the movable part 1022, the time for the movable part 1022 to reciprocate once will exceed the range of 2s~3s. For example, if the movable part 1022 is completely separated from the fixed part 1021, the time for the movable part 1022 to reciprocate once may be very short, about 1s; or, if the movable part 1022 does not move smoothly or even stops, the time for the movable part 1022 to reciprocate once may be very long, about 4s or even longer.
[0072] The alarm device 5 can determine whether the movable part 1022 has abnormal movement according to the time interval obtained by the timer. If the time interval is found to exceed the allowable range before the design life is reached, it can be determined that the movable part 1022 has abnormal movement, and the alarm device 5 can broadcast a second sound warning message and / or emit a second light warning message.
[0073] See also Figure 3 In this embodiment, the magnetic induction component 2 includes an adjustable base 201 having a receiving groove 2012a and a Hall sensor 202 installed in the adjustable base 201. Further, the adjustable base 201 includes a fixed base 2011, a rotating box 2012, a supporting plate 2013, and a screw part 2014.
[0074] The rotating box 2012 is located above the fixed base 2011 and is provided with the receiving groove 2012a; the notch position of the receiving groove 2012a is provided with an annular limiting portion 2012b for limiting the Hall sensor 202 from escaping from the receiving groove 2012a.
[0075] The supporting plate 2013 is located in the containing groove 2012a and fixedly connected to the rotating box 2012, and is used to support the Hall sensor 202; the lower end of the screw portion 2014 is fixedly arranged on the top of the fixed base 2011, and the upper end of the screw portion 2014 is threadedly connected to the rotating box 2012. Further, the supporting plate 2013, the screw portion 2014 and the fixed base 2011 are all provided with a wire hole 2015 extending from top to bottom, and the bottom surface of the fixed base 2011 is provided with a wire groove 2011a connected with the wire hole 2015.
[0076] The fixed base 2011 is fixed to the bed frame 101 by means of gluing or Velcro, and the height position of the supporting plate 2013 can be adjusted up and down by turning the rotating box 2012, thereby fine-tuning the position of the Hall sensor 202 to adjust the detection sensitivity of the Hall sensor 202 to the magnet 3.
[0077] The wire 2021 of the Hall sensor 202 can extend downward into the wire hole 2015 and then extend horizontally to the outside of the fixed base 2011 through the wire groove 2011a. This design can prevent the wire 2021 from interfering with the rotation operation of the rotating box 2012.
[0078] In summary, the aging test equipment provided in this embodiment has the following advantages:
[0079] ① The current number of movements of the movable part 1022 can be known by simply observing the value displayed on the digital display counter 4, so the electric bed 1 can be subjected to a mechanized aging test, thereby improving accuracy and reducing labor costs;
[0080] ② The alarm device 5 can send corresponding warning information according to the test results to further reduce human intervention;
[0081] ③ The height of the Hall sensor 202 can be fine-tuned by twisting the rotating box 2012 , thereby adjusting the detection sensitivity of the Hall sensor 202 to the magnet 3 , and the operation of twisting the rotating box 2012 will not be interfered by the wire 2021 .
