DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1-6 As shown, an integrated temperature and humidity recorder includes a housing 100, a PCB board 200 is arranged inside the housing 100, a USB gold finger 300 is fixedly installed on the right end of the PCB board 200, and the USB gold finger 300 passes through the right end of the housing 100, a button battery 400 is arranged inside the housing 100, and a display screen 500 is embedded in the top of the housing 100, the PCB board 200 and the display screen 500 are electrically connected, and the PCB board 200 and the display screen 500 are both electrically connected to the button battery 400.

[0023] A button battery 400 powers the PCB 200 and display 500. The PCB 200 transmits collected temperature and humidity information to the display 500, which displays the information in real time. A silicone sleeve 600 covers the right half of the housing 100 and the USB gold finger 300. The display 500 is located on the right half of the housing 100. The silicone sleeve 600 is made of transparent silicone and protects the display 500 and USB gold finger 300.

[0024] During use, the housing 100 comprises a lower shell 101 and an upper cover 102. The lower shell 101 has a slot for accommodating the PCB 200, and the upper cover 102 seals the opening of the lower shell 101. A first frame plate 103 is fixedly mounted on the bottom wall of the lower shell 101, and a second frame plate 104 is fixedly mounted on the bottom of the upper cover 102. The second frame plate 104 is inserted between the outer wall of the first frame plate 103 and the inner wall of the lower shell 101, thereby increasing the thickness and strength of the surrounding area of ​​the housing 100.

[0025] The top edge of the lower housing 101 and the bottom edge of the upper cover 102 are bonded together with glue, and the glue seals the joint between the lower housing 101 and the upper cover 102. A slot 105 is defined through the right end of the lower housing 101 and the second frame plate 104. The USB gold finger 300 passes through this slot, and the display screen 500 is embedded in the right half of the upper cover 102. A clearance groove 106 is defined at the bottom right end of the second frame plate 104. This clearance groove 106 allows the USB gold finger 300 to clear the way when the second frame plate 104 is inserted into the lower housing 101.

[0026] In practice, the front and rear outer walls of the first frame plate 103 are each provided with a mounting groove 107, the bottom wall of which is fixedly mounted with a buckle 108, and the front and rear inner walls of the second frame plate 104 are each provided with a buckle 109, into which the buckle 108 is buckled, thereby enhancing the firmness of the connection between the lower housing 101 and the upper cover 102.

[0027] Specifically, the left half of the PCB board 200 is provided with a temperature and humidity collection unit 201, a push switch 202, and an indicator light 203. Three holes are provided through the top of the housing 100, through which the temperature and humidity collection unit 201, the push switch 202, and the indicator light 203 pass. The temperature and humidity collection unit 201 is used to collect temperature and humidity information. When the silicone sleeve 600 is placed on the right half of the housing 100, the temperature and humidity collection unit 201, the push switch 202, and the indicator light 203 are exposed to the outside, ensuring that the temperature and humidity collection unit 201 can normally collect temperature and humidity information. A storage unit 204 is provided on the right half of the PCB board 200. The storage unit 204 is used to store the temperature and humidity information collected by the temperature and humidity collection unit 201.

[0028] In practice, the silicone sleeve 600 comprises a first shell 601, which fits over the right half of the outer shell 100. A second shell 602 is integrally formed at the right end of the first shell 601. The second shell 602 fits over the USB gold finger 300. Friction between the first shell 601 and the outer shell 100 prevents the first shell 601 from separating from the outer shell 100, allowing the second shell 602 to stably protect the USB gold finger 300. Bosses 603 are fixedly mounted at the top and bottom of the left end of the first shell 601. Connecting straps 604, made of silicone and possessing a certain degree of elasticity, are rotatably connected to the two bosses 603.

[0029] By holding the middle of the connecting strap 604 and pulling it to extend it, the connecting strap 604 is then rotated relative to the boss 603 until the middle of the connecting strap 604 deflects to the left end of the housing 100. The connecting strap 604 is then released, allowing the connecting strap 604 to adhere to the left end of the housing 100. This further positions the first housing 601 to prevent it from separating from the housing 100. At the same time, the connecting strap 604 blocks the upper side of the push switch 202, preventing it from being accidentally touched or squeezed by foreign objects.

[0030] When collecting temperature and humidity information, the middle part of the connecting belt 604 can be deflected to the front or rear side of the outer shell 100, and the connecting belt 604 can be hung on the hook inside the car to prevent the outer shell 100 from being squeezed by foreign objects. A suction cup 605 is fixedly installed on the boss 603 at the bottom of the first shell 601. It can be installed by adsorbing it on the wall of the car through the suction cup 605. A third shell 606 is integrally formed at the right end of the first shell 601. The third shell 606 is mounted on the outside of the second shell 602, and a cavity is formed between the second shell 602 and the third shell 606. Therefore, the second shell 602 and the connecting belt 604 cooperate to buffer the impact force received, further ensuring the protection effect of the USB gold finger 300.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
