[0006] In some embodiments, the air passage includes a first air passage, a second air passage, and a third air passage; The first air passage is located at the end of the support clamp block away from the housing, the second air passage is located on the side of the support clamp block away from the rotating clamp block, and the third air passage is located on the side of the support clamp block.

[0007] In some embodiments, the rotating clamp further includes a fixed end, a hinged end, a first bearing portion, a second bearing portion, and a connecting shaft assembly; One end of the fixed end is connected to the housing, and the other end of the fixed end has a first through hole. One end of the hinged end has a second through hole. The first through hole and the second through hole are concentrically arranged. The first bearing portion and the second bearing portion are sleeved on the connecting shaft assembly. The first bearing portion is at least partially located in the first through hole, and the second bearing portion is at least partially located in the second through hole. The connecting shaft assembly passes through the first through hole and the second through hole so that the hinged end can rotate toward the side of the support clamp relative to the fixed end.

[0008] In some embodiments, the connecting shaft assembly includes a second bolt and a connector. The connector has a threaded hole and is detachably connected to the second bolt through the threaded hole. The connector and the second bolt pass through the first through hole and the second through hole, respectively. The first bearing portion and the second bearing portion are respectively sleeved on at least one of the second bolt and the connector.

[0009] In some embodiments, the other end of the fixed end is provided with a mounting groove, and the end of the hinged end near the housing is located in the mounting groove. The first through hole includes a first hole and a second hole. The first hole and the second hole respectively penetrate the side wall of the mounting groove. The first hole, the second through hole and the second hole are concentrically arranged and distributed in sequence. The first bearing portion is at least partially located in the first hole, and the second bearing portion is at least partially located in the second through hole. The connecting shaft assembly is sequentially inserted into the first hole, the second through hole, and the second hole, so that the hinged end can rotate toward the side of the support clamp relative to the fixed end.

[0010] In some embodiments, the connector includes a connector head and a shaft body, the connector head and the shaft body are connected, the shaft body has a threaded hole that extends to and through the connector head; The width of the connector is greater than the diameter of the shaft body. The side of the connector is provided with a first limiting surface, and the wall of the first hole is provided with a second limiting surface that cooperates with the first limiting surface.

[0011] In some embodiments, the end face of the first bearing portion near the second bearing portion is provided with a protrusion; the end face of the second bearing portion near the first bearing portion is provided with at least two grooves, each groove being arranged along the circumference of the second bearing portion, and the protrusion and the corresponding groove cooperating to limit the first bearing portion and the second bearing portion.

When the diameter of the air conditioning vent is small, after rotating the rotating clamp to the side of the support clamp, since the support clamp and the rotating clamp are relatively offset, the support clamp can be inserted into the air conditioning vent first, and then the rotating clamp can be rotated back to its original position, so that the rotating clamp and the support clamp are facing each other, thereby allowing the rotating clamp and the support clamp to be smoothly clamped and fixed to the air conditioning vent. The above settings reduce the size requirements for the support clamp and the rotating clamp. Only the support clamp needs to be able to extend into the air conditioner outlet, and the size influence of the rotating clamp can be basically ignored. Therefore, it is suitable for temperature and humidity detection of air conditioner outlets with small diameters, thereby improving the convenience of temperature and humidity detection of air conditioner outlets.

[0018] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0020] The following detailed description, in conjunction with all the accompanying drawings, describes a temperature and humidity detection device 100 provided in this application through specific embodiments.

[0021] Please refer to Figures 1 to 4 One embodiment of this utility model discloses a temperature and humidity detection device 100, including a housing 10, a temperature and humidity probe 20, a support clamp 30, a rotating clamp 40, and a circuit assembly 50. The support clamping block 30 is connected to the housing 10, and the rotating clamping block 40 is hinged to the housing 10. The rotating clamping block 40 and the support clamping block 30 can approach each other to achieve clamping, and the rotating clamping block 40 can rotate to the side of the support clamping block 30. The temperature and humidity probe 20 is mounted on the support clamp 30, and the circuit assembly 50 is mounted on the housing 10. The temperature and humidity probe 20 and the circuit assembly 50 are electrically connected.

[0022] In this embodiment, the housing 10 is used to mount the circuit assembly 50, the support clamp 30, and the rotating clamp 40. The temperature and humidity probe 20 is used to detect the temperature at the target location and acquire the temperature signal, and can transmit the temperature signal to the circuit assembly 50. The circuit assembly 50 can transmit the temperature signal to a server, etc. When the temperature and humidity detection device 100 of this embodiment is applied to the air conditioning vent of a car, it can be clamped and fixed to the air conditioning vent by the support clamp 30 and the rotating clamp 40. Figure 1 As shown, in Figure 1 In this configuration, the rotating clamping block 40 and the supporting clamping block 30 overlap and are in a clamping state, allowing them to be clamped and fixed to the air conditioner outlet. Figure 2 As shown, when the diameter of the air conditioner outlet is small, after rotating the rotating clamp 40 to the side of the supporting clamp 30, since the supporting clamp 30 and the rotating clamp 40 are offset relative to each other, the supporting clamp 30 can be inserted into the air conditioner outlet first, and then the rotating clamp 40 can be rotated back to its original position, so that the rotating clamp 40 and the supporting clamp 30 are opposite each other, thus allowing the rotating clamp 40 and the supporting clamp 30 to be smoothly clamped and fixed at the air conditioner outlet. Figure 2 As shown, in Figure 2 In the middle, the rotating clamping block 40 and the supporting clamping block 30 are offset from each other and are in a non-clamping state. At this time, the supporting clamping block 30 extends into the air conditioner outlet. Then, the rotating clamping block 40 is rotated back to its original position, resulting in... Figure 1The rotating clamp 40 and the supporting clamp 30 are clamped and fixed to the air conditioner outlet as shown. This configuration reduces the size requirements for the supporting clamp 30 and the rotating clamp 40; only the supporting clamp 30 needs to be able to extend into the air conditioner outlet, and the size influence of the rotating clamp 40 can be largely ignored, resulting in a wider detection range. Therefore, it is suitable for temperature and humidity detection of air conditioner outlets with small diameters, thereby improving the convenience of temperature and humidity detection at air conditioner outlets.

[0023] In some specific embodiments, the support clamp 30 and the housing 10 can be fixedly connected or detachably connected. The temperature and humidity probe 20, also known as a temperature and humidity sensor, may include a temperature sensing device, a signal processing circuit, and a housing. The temperature sensing device, humidity sensing device, and signal processing circuit are housed within the housing. The temperature sensing device can be a thermistor, and the humidity sensing device can be a capacitive humidity sensing element. The temperature and humidity sensing devices are located on the signal processing circuit, which is electrically connected to the circuit assembly 50. The temperature and humidity detection device 100 of this embodiment is applicable to both new energy vehicles and fuel vehicles. It is understood that, according to user needs, the temperature and humidity detection device 100 of this embodiment can also be applied to other occasions or scenarios.

[0024] In summary, the temperature and humidity detection device 100 of this embodiment can not only be clamped and fixed to the air conditioning vent of a car, but the support clamp 30 can also be inserted into the air conditioning vent with a smaller gap. Therefore, the temperature and humidity detection device 100 of this embodiment can cover the temperature and humidity detection of the air conditioning vents of more car models, can adapt to a variety of application scenarios, and meet a variety of user needs.

[0025] In some embodiments, the support clamp 30 is provided with a first receiving cavity 32, the temperature and humidity probe 20 is located in the first receiving cavity 32, and the first receiving cavity 32 is provided with an air passage 34.

[0026] In this embodiment, the first receiving cavity 32 is provided to house the temperature and humidity probe 20, which serves to house and protect the probe. Furthermore, due to the air passage 34, airflow at the target location can pass through the air passage 34 and directly contact the temperature and humidity probe 20, enabling the probe to accurately detect the temperature at the target location and generate a temperature signal.

[0027] In some embodiments, the ventilation hole 34 includes a first ventilation hole 342, a second ventilation hole 344 and a third ventilation hole 346; The first air passage 342 is located at the end of the support clamping block 30 away from the housing 10, the second air passage 344 is located on the side of the support clamping block 30 away from the rotating clamping block 40, and the third air passage 346 is located on the side of the support clamping block 30.

[0028] In this embodiment, the first air inlet 342 is the main air inlet, and the second air inlet 344 and the third air inlet 346 are the main air outlets. By setting the air inlet and air outlet, the airflow at the target location can pass through the first receiving cavity 32 to form a return airflow, thereby enabling the temperature and humidity probe 20 to accurately detect the temperature at the target location and generate a temperature signal.

[0029] In some embodiments, the first air passage 342 and the third air passage 346 are elliptical through holes. The second air passage 344 is a strip-shaped through hole. An inclined air guide groove 35 is provided on the side of the support clamp 30 away from the rotating clamp 40. The air guide groove 35 has a first end and a second end opposite to each other. The first end is located at the end of the support clamp 30 away from the housing 10, and the second end is located at the end of the support clamp 30 close to the housing 10. The depth of the air guide groove 35 gradually decreases along the direction from the first end to the second end. The second air passage 344 is located on the side wall of the first end of the air guide groove 35, thereby guiding the airflow at the third air passage 346.

[0030] In some specific embodiments, the width of the air guide groove 35 gradually increases along the direction from the first end to the second end, thereby further improving the guiding effect on the airflow of the second air passage 344. A third air passage 346 is provided on each of the two opposite sides of the support clamp 30.

[0031] Understandably, the first air vent 342 can also allow a small amount of air to be discharged, and the second air vent 344 and the third air vent 346 can also allow a small amount of air to be received.

[0032] Please refer to the above as well. Figures 5 to 7 In some embodiments, the rotating clamp 40 further includes a fixed end 42, a hinged end 44, a first bearing portion 46, a second bearing portion 48, and a connecting shaft assembly 49; One end of the fixed end 42 is connected to the housing 10, and the other end of the fixed end 42 is provided with a first through hole 422. One end of the hinge end 44 is provided with a second through hole 442. The first through hole 422 and the second through hole 442 are concentrically arranged. The first bearing part 46 and the second bearing part 48 are sleeved on the connecting shaft assembly 49. The first bearing part 46 is at least partially located in the first through hole 422, and the second bearing part 48 is at least partially located in the second through hole 442. The connecting shaft assembly 49 passes through the first through hole 422 and the second through hole 442 so that the hinge end 44 can rotate relative to the fixed end 42 toward the side of the support clamp 30.

[0033] In this embodiment, one end of the fixed end 42 and the housing 10 can be fixedly connected or detachably connected. A fixed connection is formed between the connecting shaft assembly 49 and the sidewall of the first through hole 422 through the cooperation of the connecting shaft assembly 49 and the first bearing portion 46. The connecting shaft assembly 49 and the second bearing portion 48 cooperate to allow relative rotation between their sidewalls, thereby enabling the hinge end 44 to rotate relative to the fixed end 42. The first bearing portion 46 and the second bearing portion 48 together form a complete bearing. By providing the fixed end 42 and the hinge end 44, it is ensured that the hinge end 44 can rotate relative to the fixed end 42 toward the side of the support block 30, and that the fixed end 42 and the hinge end 44 are easy to install and maintain.

[0034] In some specific embodiments, the fixed end 42 is a block structure, and the fixed end 42 and the housing 10 can be connected by a bolt assembly, making disassembly and assembly convenient. The hinge end 44 is made of a metal alloy material. The first bearing part 46 and the second bearing part 48 can be made of nylon material. With this arrangement, a damping effect can be generated between the first bearing part 46 and the second bearing part 48, so that the hinge end 44 has a damped feel when rotating relative to the fixed end 42. The user can control the rotation angle of the hinge end 44 relative to the fixed end 42 more accurately. Under the action of no external force, the hinge end 44 will not swing freely relative to the fixed end 42. It is understood that the first bearing part 46 and the second bearing part 48 can also be made of different materials to achieve different damping effects.

[0035] In some specific embodiments, the first bearing portion 46 is fixedly disposed within the first through hole 422, and the second bearing portion 48 is fixedly disposed within the second through hole 442. That is, the first bearing portion 46 is fixed relative to the fixed end 42, and the second bearing portion 48 is fixed relative to the hinge end 44. Since the hinge end 44 rotates relative to the fixed end 42, the second bearing portion 48 rotates relative to the first bearing portion 46. In other words, the second bearing portion 48 is movable, while the first bearing portion 46 is fixed, thereby enabling the hinge end 44 to rotate relative to the fixed end 42 with a damped feel.

[0036] In some specific embodiments, one end of the housing 10 is provided with an arc-shaped notch 12, and the end of the fixed end 42 near the housing 10 is arc-shaped. The arc-shaped end of the fixed end 42 is located in the arc-shaped notch 12. The arc-shaped notch 12 can limit the arc-shaped end of the fixed end 42, thereby further improving the connection strength between the fixed end 42 and the housing 10.

[0037] In some specific embodiments, the support clamp 30 includes an upper shell 36 and a bottom cover 38, which are detachably connected. The upper shell 36 is detachably connected to the housing 10, and the bottom cover 38 is detachably connected to the upper shell 36. A first receiving cavity 32 is formed between the bottom cover 38 and the upper shell 36.

[0038] Furthermore, the bottom cover 38 and the upper shell 36 are detachably connected by a bolt assembly, and the upper shell 36 and the shell 10 are detachably connected by another bolt assembly, making disassembly and assembly convenient.

[0039] Furthermore, the bolt assembly includes a first bolt and a nut.

[0040] In some embodiments, the connecting shaft assembly 49 includes a second bolt 492 and a connector 494. The connector 494 has a threaded hole and is detachably connected to the second bolt 492 through the threaded hole. The connector 494 and the second bolt 492 pass through the first through hole 422 and the second through hole 442. The first bearing portion 46 and the second bearing portion 48 are respectively sleeved on at least one of the second bolt 492 and the connector 494.

[0041] In this embodiment, the connector 494 is detachably connected via a threaded hole and the second bolt 492, facilitating easy assembly and disassembly. The locking and fixing of the second bolt 492 and the connector 494 secures the fixed end 42 and the hinged end 44, preventing them from detaching. Furthermore, the first bearing portion 46 and the second bearing portion 48 are respectively fitted onto at least one of the second bolt 492 and the connector 494, allowing the hinged end 44 to rotate relative to the fixed end 42 towards the side of the support clamp 30.

[0042] In some specific embodiments, the first bearing portion 46 and the second bearing portion 48 are respectively sleeved on the connecting member 494. When the hinged end 44 rotates relative to the fixed end 42 toward the side of the support clamping block 30, the extension line of the rotation axis of the hinged end 44 can pass through and be perpendicular to the surface of the support clamping block 30 and parallel to the surface of the rotating clamping block 40. The connecting member 494 can be a nut.

[0043] In some embodiments, the other end of the fixed end 42 is provided with a mounting groove 424, and the end of the hinged end 44 near the housing 10 is located in the mounting groove 424. The first through hole 422 includes a first hole 4222 and a second hole 4224. The first hole 4222 and the second hole 4224 respectively penetrate the side wall of the mounting groove 424. The first hole 4222, the second through hole 442 and the second hole 4224 are concentrically arranged and distributed in sequence. The first bearing portion 46 is at least partially located in the first hole 4222, the second bearing portion 48 is at least partially located in the second through hole 442, and the connecting shaft assembly 49 is sequentially inserted into the first hole 4222, the second through hole 442, and the second hole 4224, so that the hinge end 44 can rotate relative to the fixed end 42 toward the side of the support clamp 30.

[0044] In this embodiment, by providing a mounting groove 424, the mounting groove 424 has a limiting effect on the end of the hinge end 44 near the housing 10, ensuring that the hinge end 44 rotates about the rotation axis relative to the fixed end 42 toward the side of the support clamp 30, and preventing the rotation direction of the hinge end 44 from deviating. The first hole 4222 can accommodate the mounting of the first bearing part 46, the second through hole 442 can accommodate the mounting of the second bearing part 48, and the second hole 4224 is used for the second bolt 492 to pass through, thereby further ensuring the rotation of the hinge end 44 relative to the fixed end 42, and preventing the hinge end 44 from disengaging or rotating away from the fixed end 42.

[0045] In some embodiments, the connector 494 includes a connector 4942 and a shaft body 4944, the connector 4942 and the shaft body 4944 are connected, and a threaded hole is provided in the shaft body 4944, the threaded hole extends to the connector 4942 and passes through the connector 4942. The width of the connector 4942 is greater than the diameter of the shaft body 4944. The side of the connector 4942 is provided with a first limiting surface 49422, and the wall of the first hole 4222 is provided with a second limiting surface 42222 that cooperates with the first limiting surface 49422.

[0046] In this embodiment, the cooperation of the first limiting surface 49422 and the second limiting surface 42222 ensures that the connector 4942 and the shaft body 4944 will not rotate relative to the fixed end 42 when and after installation. This facilitates the installation of the connector 494 and the second bolt 492 and prevents loosening of the connector 494 and the second bolt 492 after installation. Since the width of the connector 4942 is greater than the diameter of the shaft body 4944, the first bearing portion 46 can be installed on the shaft body 4944, and the connector 4942 and the first bearing portion 46 are at least respectively installed and fixed in the first hole 4222.

[0047] In some specific embodiments, the connector 4942 and the shaft body 4944 are integrally formed. The first hole 4222 and the second hole 4224 are both stepped holes. That is, the first hole 4222 includes a countersunk hole and a first cylindrical hole. The countersunk hole has a second limiting surface 42222 on its wall. The diameter of the countersunk hole is larger than the diameter of the first cylindrical hole. The countersunk hole is located on the side of the fixed end 42 near the support clamp 30. The connector 4942 is located in the countersunk hole, and the shaft body 4944 passes through the first cylindrical hole. The second hole 4224 includes a second cylindrical hole and a third cylindrical hole. The diameter of the second cylindrical hole is larger than the diameter of the third cylindrical hole. The second cylindrical hole is located on the side of the fixed end 42 away from the support clamp 30. The bolt head of the second bolt 492 is located in the second cylindrical hole, and the bolt shank of the second bolt 492 passes through the third cylindrical hole. With this configuration, when installing the connector 494 and the second bolt 492, the second limiting surface 42222 and the first limiting surface 49422 of the countersunk hole cooperate with each other, preventing the connector 494 from rotating. Since the second bolt 492 can rotate in the second cylindrical hole and the third cylindrical hole, it is convenient to install the second bolt 492 and the connector 494.

[0048] In some embodiments, the first bearing portion 46 has a protrusion 462 on its end face near the second bearing portion 48; the second bearing portion 48 has at least two grooves 482 on its end face near the first bearing portion 46, each groove 482 being arranged along the circumference of the second bearing portion 48, and the protrusion 462 and the corresponding groove 482 cooperating to limit the first bearing portion 46 and the second bearing portion 48.

[0049] In this embodiment, the first bearing portion 46 is at least partially located in the first through hole 422, and is fixed relative to the fixed end 42 and the connecting shaft assembly 49. The second bearing portion 48 is at least partially located in the second through hole 442, and is fixed relative to the hinge end 44. The second bearing portion 48 rotates relative to the connecting shaft assembly 49, while the hinge end 44 rotates relative to the fixed end 42. Therefore, the second bearing portion 48 can rotate relative to the first bearing portion 46. When the first bearing portion 46 and the second bearing portion 48 rotate relative to each other, the protrusion 462 can engage with the corresponding groove 482. Through the cooperation of the groove 482 and the protrusion 462, the hinge end 44 and the fixed end 42 have at least two fixed positions.

[0050] In some specific embodiments, there are four protrusions 462 distributed circumferentially along the first bearing portion 46, with a preset distance between any two adjacent protrusions 462. There are also 17 grooves 482 distributed circumferentially along the second bearing portion 48, with a preset distance between any two adjacent grooves 482. With this arrangement, when the hinge end 44 rotates relative to the fixed end 42, the four protrusions 462 can engage with the four grooves 482, thus allowing the hinge end 44 to remain relatively fixed relative to the fixed end 42 after rotating to a preset position. Furthermore, the rotation of the hinge end 44 relative to the fixed end 42 produces a damped, jumping sensation. It is understood that in other embodiments, the number of protrusions 462 and grooves 482 can be designed according to user requirements, which will not be elaborated upon here.

[0051] Please refer to the following: Figures 1 to 3 In some embodiments, the circuit assembly 50 includes a PCB board 52, a Bluetooth module 54 and a power module 56, and a second receiving cavity 14 is provided inside the housing 10.
