Problems solved by technology

[0003] The current installation method of the temperature measuring device is to install the charging terminal, and then make the charging terminal and the temperature measuring device fit together, but because there is no pressure between the charging terminal and the temperature measuring device, there are actually many tiny gaps in the bonding area , leading to the inability to accurately measure the temperature of the charging terminal, and the temperature control system cannot adjust the temperature of the charging system in time, resulting in excessive temperature rise of the charging system and causing charging failure

Embodiment 1

[0052] The invention provides a temperature measuring structure, such as Figure 1-Figure 5 As shown, it includes a bracket 2 and a temperature measuring element 1. The bracket 2 has a first surface 21, and a groove 22 for accommodating the temperature measuring element 1 is arranged on the first surface 21. The temperature measuring element 1 has a temperature measuring surface 11, and the temperature measuring surface 11 At least partially protruding from the first surface 21 , the temperature measuring surface 11 forms a variable angle with the first surface 21 .

[0053] During specific implementation, when the temperature measuring element 1 is placed in the groove, the temperature measuring surface 11 protrudes from the first surface 21, and the temperature measuring surface 11 of the temperature measuring element 1 and the first surface 21 on the bracket 2 form a variable angle, After installing the measured object 3, the measured object 3 can be in contact with the tem...

Embodiment 2

[0108] The present invention provides a charging device, which includes the object under test 3 and the temperature measuring structure in the first embodiment above.

[0109] Further, when the charging device is assembled, the temperature measuring element 1 is in contact with the measured object 3, the temperature measuring surface 11 is in contact with the measured object 3 and exerts pressure on the measured object 3, and the temperature measuring element 1 measures the measured object 3. The temperature of object 3.

[0110] During specific implementation, when the charging device is assembled and used, the measured object 3 and the temperature measuring element 1 generate stress between the rotating shaft 13 and the third surface 103, so that the temperature measuring surface 11 and the first surface 21 form a certain angle. At this time, pressure is generated between the temperature measuring surface 11 and the measured object 3, so that the temperature measuring elemen...

Embodiment 3

[0125] The present invention also provides a motor vehicle, which includes the above-mentioned temperature measuring structure or the above-mentioned charging device.

Abstract

The invention relates to the field of electrical connection, in particular to a temperature measuring structure, a charging device and a motor vehicle. The temperature measuring structure comprises a support and a temperature measuring element, the support is provided with a first surface, the first surface is provided with an area for accommodating the temperature measuring element, the temperature measuring element is provided with a temperature measuring surface, at least part of the temperature measuring surface protrudes out of the first surface, and a variable included angle is formed between the temperature measuring surface and the first surface. According to the invention, the temperature measuring surface of the temperature measuring element can be tightly attached to the measured object, and the temperature measuring surface can apply a certain pressure to the measured object without the help of an additional device, so that the temperature measuring element measures temperature data closest to the actual temperature of the measured object. Therefore, a worker or a corresponding processor can know the temperature of the measured object more timely and accurately, and the condition that the temperature measuring surface is separated from the measured object in the subsequent use process of the temperature measuring element is avoided.

Description

technical field [0001] The invention relates to the field of electrical connection, in particular to a temperature measuring structure, a charging device and a motor vehicle. Background technique [0002] At present, the charging gun head and the charging stand of new energy vehicles will have a charging terminal with a plug-in structure, and the charging terminal is fixed on the charging gun head or the terminal card seat of the charging stand. When the car is charging, the current at the charging terminal increases rapidly, and the calorific value rises sharply. Therefore, for safety reasons, many manufacturers will install a temperature measuring device at the charging terminal. The contact temperature measuring device is simple, reliable and has high measurement accuracy. However, the temperature measurement device must be in contact with the measured medium to measure the temperature. The installed charging terminal needs to maintain a certain pressure with the tempera...
