Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
A temperature measuring structure is shown in figures 1-6 and comprises a support 1, a temperature sensor 2 and a measured object 5, wherein the temperature sensor 2 is arranged on the support 1 and is in contact with at least part of the measured object 5; at least one pressure maintaining mechanism 4 is further arranged on the support 1, and the pressure maintaining mechanism 4 exerts force on the object to be measured 5 to enable the object to be measured 5 to be clamped between the temperature sensor 2 and the pressure maintaining mechanism 4.
The current temperature measurement structure can only enable the measured object 5 to be in contact with the temperature sensor 2, when the environment vibrates, the measured object 5 and the temperature sensor 2 can deviate and cannot be in close contact, the temperature measured by the temperature sensor 2 is inaccurate, the control system can execute wrong temperature control measures according to inaccurate temperature information, and the temperature near the measured object 5 is easily caused to be too high to cause burning.
The temperature sensor 2 and the pressure holding mechanism 4 are provided on the bracket 1 with an area for receiving the object 5 to be measured formed therebetween, and when the object 5 to be measured is inserted into the area, the pressure holding mechanism 4 is subjected to a pressing force and simultaneously provides a clamping force to the object 5 to be measured so as to be clamped between the pressure holding mechanism 4 and the temperature sensor 2. At this time, the temperature sensor 2 is brought into contact with at least a part of the measured object 5 to measure the temperature of the measured object 5. One or more pressure maintaining mechanisms 4 can be arranged as required, and the plurality of pressure maintaining mechanisms 4 can provide stronger pressing force to enable the object to be measured 5 and the temperature sensor 2 to be attached more closely to obtain a measured value closer to a real temperature value.
In some embodiments, the pressure maintaining mechanism 4 and the temperature sensor 2 are respectively located on two sides of the object to be measured 5.
The pressure holding mechanism 4 can provide a pressing force to the measured object 5 so that the measured object 5 is clamped between the pressure holding mechanism 4 and the temperature sensor 2. Therefore, the object to be measured 5 and the temperature sensor 2 are ensured to be attached closely, and the temperature of the object to be measured 5 monitored by the temperature sensor 2 can be closer to the true value. Reasonable clamping force can ensure the tightness of the measured object 5 and the temperature sensor 2 and can prevent the measured object 5 from being difficult to install.
In some embodiments, the force applied by the pressure retention mechanism 4 to the object 5 is between 0.05N and 195N.
In order to test the effect of the pressure provided by the pressure holding mechanism 4 on the accuracy of the temperature sensor 2, the inventors made relevant tests. The inventor chooses the same measured object 5 and the same temperature sensors 2 are arranged on the same bracket 1. The method comprises the steps of selecting a test sensor to be arranged on a measured object 5 and tightly attached to the measured object 5, selecting different pressure retaining mechanisms 4, enabling different pressure retaining mechanisms 4 to provide different reset forces and different pressures between a temperature sensor 2 and the measured object 5, enabling the temperature of the measured object 5 to start rising after the measured object 5 works, enabling the temperature to tend to be stable after 20 minutes, recording a temperature value y collected by the test sensor and a temperature value x collected by the temperature sensor 2 connected with the different pressure retaining mechanisms 4 at the same time, and calculating the ratio of x/y, wherein the ratio of x/y is greater than 99.95% and is an ideal state. The results are shown in Table 1.
Table 1: effect of pressure provided by pressure maintenance mechanism on temperature sensor accuracy
As can be seen from table 1, when the force applied by the pressure holding mechanism 4 to the object 5 to be measured is less than 0.05N, the temperature value acquired by the temperature sensor 2 is too different from the temperature value acquired by the test sensor, and the ratio of the temperature value acquired by the temperature sensor 2 to the temperature value acquired by the test sensor is less than 99.95%, so that the pressure holding mechanism 4 selected by the inventor applies a force to the object 5 to be measured of 0.05N or more, and when the force applied by the pressure holding mechanism 4 to the object 5 to be measured is more than 195N, the temperature measured by the temperature sensor 2 is very close to the temperature measured by the test sensor, and the application of a larger force has no influence, and the pressure holding mechanism 4 providing a larger force causes the installation of the object 5 to be measured to be more difficult, so that the pressure provided by the pressure holding mechanism 4 selected by the inventor is 0.05N to 195N.
In some embodiments, the pressure maintenance mechanism 4 applies different force values to the object 5 at different ambient temperatures. Under most circumstances, the ambient temperature of the object to be measured 5 can change greatly when in use, the gap between the object to be measured 5 and the temperature sensor 2 can increase along with the increase of the ambient temperature, so that the temperature sensor 2 cannot accurately measure the actual temperature of the object to be measured 5, the temperature measured by the temperature sensor 2 is inaccurate, and the control system can execute wrong temperature control measures according to inaccurate temperature information to cause the related devices to be burnt due to overhigh temperature. Therefore, when the ambient temperature increases, the volume of the pressure maintaining mechanism 4 also increases to provide a larger pressure, so that the measured object 5 and the temperature sensor 2 are closely attached to each other, and the temperature sensor 2 can accurately measure the actual temperature of the measured object 5. When the ambient temperature decreases, the volume of the pressure holding mechanism 4 also decreases, but the gap between the object 5 to be measured and the temperature sensor 2 also decreases, so that the object 5 to be measured and the temperature sensor 2 are closely attached.
The pressure holding mechanism 4 has a property of deforming with a change in the ambient temperature, and the pressure holding mechanism 4 may be made of a material having a large expansion rate, and the material having such a large expansion rate can change its entire volume with a change in the ambient temperature. The pressure retaining mechanism 4 can also be made by combining materials with different expansion rates, and when the environmental temperature changes, the pressure retaining mechanism 4 combined by the materials with different expansion rates can be bent or twisted, so that greater pressure is generated to be applied to the object 5 to be measured, and the object 5 to be measured is tightly attached to the temperature sensor 2.
In some embodiments, the pressure maintaining mechanism 4 is an elastic sheet, as shown in fig. 2, the elastic sheet includes a fixed portion 41 and an elastic portion 42 connected to each other, the fixed portion 41 is fixedly connected to the bracket 1, and the elastic portion 42 can deform to generate an elastic force. After the object 5 is installed, the elastic portion 42 deforms, so that a continuous pressing force is generated to the object 5, and the object 5 can be tightly attached to the temperature sensor 2.
Further, the holder 1 is provided with a spring piece seat 43, and the fixing portion 41 is provided on the spring piece seat 43. As shown in fig. 3, the fixing portion 41 may be welded to the elastic sheet seat 43, or may be connected to the elastic sheet seat 43 in a screw or snap manner, so as to facilitate replacement of the elastic sheet when the elasticity of the elastic portion 42 is insufficient.
In some embodiments, the fixed portion 41 and the extending direction of the elastic portion 42 form a set angle, and the angle change between the fixed portion 41 and the extending direction of the elastic portion 42 generates an elastic force. As shown in fig. 4, the elastic portion 42 and the object 5 are pressed against each other, and the included angle between the elastic portion 42 and the fixed portion 41 changes, so that the elastic portion 42 generates an elastic force tending to return to attach the object 5 to the temperature sensor 2. Furthermore, the elastic portion 42 and the fixing portion 41 may form a V shape or a U shape, and an elastic force is generated by a change of an included angle.
In some embodiments, the pressure retention mechanism 4 includes a support portion fixed to the bracket and an elastic body provided on one side of the support portion with respect to the object 5 to be measured. The elastic body can generate elasticity after being squeezed so that the measured object 5 can be attached to the temperature sensor 2.
Furthermore, the elastic body is elastic rubber or elastic soft rubber or a compression spring. The elastic rubber, the elastic soft rubber and the compression spring belong to traditional materials and are easy to select and process.
In some embodiments, the holder 1 has a recess 11, as shown in fig. 2, and the temperature sensor 2 is disposed in the recess 11. The groove 11 can better fix the temperature sensor 2 and prevent the temperature sensor 2 from being separated from the working position during shaking. Recess 11 is at the terminal surface of one side that temperature sensor 2 put into, interior limit edges and corners department at recess 11, set up chamfer or radius, can make temperature sensor 2 under the effect of direction, more smooth insert in recess 11, recess 11 still sets up on the terminal surface of one side that temperature sensor 2 put into and has elastic blocking hook, when temperature sensor 2 puts into recess 11, can remove the position that does not influence temperature sensor 2 and put into with blocking hook, put into the back when temperature sensor 2, blocking hook can block temperature sensor 2's terminal surface, make temperature sensor 2 can not break away from in the recess 11. If it is necessary to disengage the temperature sensor 2 from the recess 11, the blocking hook needs to be deformed to move to a position that does not affect the extraction of the temperature sensor 2.
In some embodiments, the groove 11 is provided with an opening facing the side of the object to be measured 5, and the temperature sensor 2 has a temperature measuring surface which is flush with or protrudes from the outer side surface of the opening. As shown in fig. 4, the temperature measuring surface protrudes from the opening or is flush with the opening, and can be better attached to the measured object 5, so that the temperature value measured by the temperature sensor 2 is closer to the true value.
In some embodiments, the recess 11 is provided with a resilient element on the opposite side of the opening, when the temperature measuring surface protrudes outside the opening, which resilient element exerts a force on the temperature sensor 2. Thus, the elastic element and the pressure maintaining mechanism 4 apply elastic force from two sides of the measured object 5 respectively, the force of the elastic element is directly applied to the temperature sensor 2 and then applied to the measured object 5, and the elastic force is applied from two sides, so that the attaching degree of the measured object 5 and the temperature sensor 2 can be further improved.
The force value applied by the elastic element to the temperature sensor 2 is 0.05N-195N.
In order to test the effect of the pressure provided by the resilient element on the accuracy of the temperature sensor 2, the inventors made relevant tests. The inventor chooses the same measured object 5 and the same temperature sensors 2 are arranged on the same bracket 1. The method comprises the steps of selecting a test sensor to be arranged on a tested object 5 and tightly attached to the tested object 5, selecting different elastic elements, enabling different elastic elements to provide different reset forces and different pressures between a temperature sensor 2 and the tested object 5, enabling the temperature of the tested object 5 to start rising after the tested object 5 works, enabling the temperature to tend to be stable after 20 minutes, recording a temperature value y collected by the test sensor and a temperature value x collected by the temperature sensor 2 connected with different elastic elements at the same time, and calculating the ratio of x/y, wherein the ratio of x/y is greater than 99.95% and is an ideal state. The results are shown in Table 2.
Table 2: influence of the pressure provided by the elastic element on the accuracy of the temperature sensor 2
As can be seen from table 2, when the force applied by the elastic element to the object 5 to be measured is less than 0.05N, the temperature value acquired by the temperature sensor 2 is too different from the temperature value acquired by the test sensor, and the ratio of the temperature value acquired by the temperature sensor 2 to the temperature value acquired by the test sensor is less than 99.95%, so that the elastic element selected by the inventor applies a force to the object 5 to be measured of 0.05N or more, and when the force applied by the elastic element to the object 5 to be measured is more than 195N, the temperature measured by the temperature sensor 2 is very close to the temperature measured by the test sensor, and then the application of a larger force has no effect, and the elastic element providing a larger force will make the installation of the object 5 to be measured more difficult, so that the pressure provided by the elastic element selected by the inventor is 0.05N-195N.
Furthermore, the elastic element is elastic rubber or elastic soft rubber or a compression spring. The elastic rubber, the elastic soft rubber and the compression spring belong to traditional materials and are easy to select and process.
Furthermore, the compression spring is electrically connected with the temperature sensor 2 and is used for transmitting data of the temperature sensor 2. That is to say the compression spring itself has the function of outputting data. Compression spring one end and temperature sensor 2 electric connection, the other end and data line or circuit board are connected, reconnection temperature acquisition device, have just so avoided setting up the too complicated problem of battery charging outfit internal layout that the data line caused alone from temperature sensor 2. The temperature sensor collects the temperature of the measured object 5 and finally sends the temperature to the temperature collecting device through the elastic component capable of outputting data.
In some embodiments, the bracket 1 further includes a snap ring 31, and the snap ring 31 is provided with a through opening 32, and a width of the through opening 32 is smaller than a diameter of the snap ring 31. The clamping ring 31 is used for clamping the bracket 1 at a required place, so that the temperature measuring structure can be conveniently applied to various occasions.

The fixing 6 is used for fixing the stand 1, the column 61 can be inserted into the fitting hole of the fitting position, and the cap 62 can prevent the column 61 from coming out of the fitting hole.

The fixing column 6 is installed, and then the clamping ring 31 is clamped with the clamping bulge 71, so that the bracket 1 is fixed on the fixing plate 7. In other cases, the fastening ring 31 may be fastened to the fastening protrusion 71, and then the fixing post 6 may be fixed to the fixing plate 7.
In some embodiments, the clamping protrusion 71 includes a fixing frame and a fixing shaft disposed on the fixing frame, the fixing frame is disposed on the fixing plate 7, the fixing shaft is clamped in the clamping ring 31 through the through opening 32, and the width of the through opening 32 is smaller than or equal to the diameter of the fixing shaft.
