Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, and specifically relates to a sensor housing and a building data acquisition sensor. Background Technology

[0002] A sensor is a device that can sense and detect specific physical or chemical quantities, converting these quantities into measurable signal outputs. Sensors are widely used in industrial control, environmental monitoring, medical diagnosis, security monitoring, and other fields, helping people acquire various information in real time and perform effective monitoring and control. Common sensors include temperature sensors, pressure sensors, optical sensors, humidity sensors, and motion sensors. With the development of technology, the types and application areas of sensors continue to expand, making them an indispensable and important part of modern society.

[0003] In building structural health monitoring, multiple wireless sensors, such as acceleration, strain, temperature, and humidity sensors, are typically installed on or inside the building structure to collect data. Sensors installed on the building surface are exposed to harsh environments like thunderstorms, requiring a certain level of sealing to prevent rainwater from entering and damaging the sensors. However, outdoor temperatures can also be high, and even well-sealed sensors inevitably have poor heat dissipation, leading to a shorter lifespan. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a sensor housing and a building data acquisition sensor, which aims to solve the problem of the lack of a consistent sensor housing that prevents rainwater from entering and has high heat dissipation performance in the prior art.

[0005] The present invention provides a sensor housing, characterized in that it includes:

[0006] A housing for accommodating a sensor module for collecting building parameters, the housing having at least one fixed side for fixing the sensor housing to the building to be measured;

[0007] The fixed side has several heat dissipation channels that extend from the inside of the sensor housing to the outside of the sensor housing and pass through the fixed side. The heat dissipation channels have air inlets and air outlets that are staggered.

[0008] The aforementioned sensor housing, through the cooperation of the bottom and side plates of the housing and cover plate, forms a relatively enclosed accommodating space for the installation and protection of the sensor's electronic components. Furthermore, a heat dissipation channel is provided on the bottom plate, allowing the accommodating space to communicate with the outside, thereby improving the sensor's heat dissipation effect. Since the heat dissipation channel is located at the bottom, the probability of rainwater entering the sensor's interior is reduced. In addition, the air inlet and outlet of the heat dissipation channel are staggered, resulting in a longer channel length and a path that is not vertical but inclined, curved, or irregular. This ensures that even if some rainwater enters the heat dissipation channel under airflow, it will collide with the inner wall or bends of the channel, slowing down or stopping, and then flowing back out through the air outlet under gravity. Thus, through the structural design and positional distribution of the heat dissipation channel, the function of preventing rainwater from entering is achieved while ensuring effective heat dissipation inside the sensor. Therefore, this invention solves the problem of the lack of a consistent sensor housing that prevents rainwater ingress and has high heat dissipation performance in the prior art.

[0011] Preferably, the heat dissipation channel is serpentine with at least four bends, and the bend near the air outlet is higher than the bend near the air inlet.

[0012] Preferably, the air outlet of one of the heat dissipation channels is located above the air inlet of the adjacent heat dissipation channel, so that the trajectory of the multiple heat dissipation channels arranged sequentially forms a closed pattern with an outer C-shape and an inner serpentine shape.

[0013] Preferably, the housing includes a base plate and a plurality of side plates disposed on the base plate. The base plate is disposed on the fixed side. The base plate and the side plates enclose a housing space for accommodating the sensor module. The base plate is provided with a plurality of heat dissipation channels. A surrounding plate is provided below the base plate. Fixed plates are provided on both sides of the surrounding plate. Fixed holes are provided on the fixed plates.

[0014] Preferably, the sensor housing further includes a cover plate, which is disposed above the housing to close the opening at the top of the housing. The cover plate has a first protrusion and a second protrusion extending outward from the outer side and the middle part of the bottom, respectively. The groove formed between the first protrusion and the second protrusion is adapted to the side plate. A limiting block is provided on the inner side of the first protrusion. A groove adapted to the limiting block is provided on the outer side of the side plate. A sealing groove is provided on the outer side of the second protrusion. A sealing ring is provided in the sealing groove. The sealing groove is also provided on the inner side of the side plate. The two sealing grooves are adapted to each other.

[0015] Preferably, the heat dissipation channel is provided with multiple layers of filters, and a drying element is provided between adjacent filters.

[0016] Preferably, the housing is further provided with a battery compartment, the side plate is provided with the opening to connect the battery compartment to the outside, the opening is provided with a sealing plate, the sealing plate is provided with a limiting rod and the sealing groove on one side, the side plate is provided with a limiting groove adapted to the limiting rod and the sealing groove, the two sealing grooves are adapted to each other and a sealing ring is provided in the sealing groove.

[0028] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0029] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Please see Figures 1 to 7 The image shows a sensor housing in one embodiment of the present invention, including a housing 10, which is at least used to house a sensor module for collecting building parameters. The housing 10 has at least one fixed side, which is used to fix the sensor housing to the building to be measured.

[0033] The fixed side has several heat dissipation channels 13, which extend from the inside of the sensor housing to the outside of the sensor housing and pass through the fixed side. The heat dissipation channels 13 have air inlets and air outlets, which are staggered.

[0034] Understandably, the housing 10 and the bottom plate 11 and side plate 12 of the cover plate 20 cooperate to form a relatively enclosed accommodating space for the installation and protection of the sensor's electronic components. Furthermore, a heat dissipation channel 13 is provided on the bottom plate 11 to allow the accommodating space to communicate with the outside, thereby improving the sensor's heat dissipation effect. Since the heat dissipation channel 13 is located at the bottom, the probability of rainwater entering the sensor is reduced. In addition, the air inlet and outlet of the heat dissipation channel 13 are staggered, resulting in a longer channel length and a path that is not vertical but inclined, curved, or irregular. This ensures that even if some rainwater enters the heat dissipation channel 13 under airflow, it will collide with the inner wall or bends of the channel 13, slowing down or stopping, and then flowing back out through the air outlet under gravity. Thus, through the structural design and positional distribution of the heat dissipation channel 13, the function of preventing rainwater from entering is achieved while ensuring the heat dissipation effect inside the sensor. Therefore, this invention solves the problem of insufficient heat dissipation effect of the sensor housing in the prior art.

[0035] Specifically, the heat dissipation channel 13 is stepped with at least two steps, and the step height near the air outlet is higher than the step height near the air inlet. In practice, the air inlet and outlet of the heat dissipation channel 13 can be staggered by using a straight, angled heat dissipation channel 13. However, this arrangement has limited effectiveness in preventing rainwater from entering, and the sensor may not be vertically mounted. The installation angle, external forces, or wind could cause the sensor to tilt, potentially resulting in the tilted heat dissipation channel 13 aligning with the direction of rainwater flow, thus preventing the heat dissipation channel 13 from effectively preventing rainwater from entering. Therefore, in practice, the heat dissipation channel 13 can be designed as a stepped structure. The multiple steps create a barrier to prevent rainwater from entering the sensor while ensuring the heat dissipation effect of the heat dissipation channel 13 itself.

[0036] Furthermore, the heat dissipation channel 13 is serpentine with at least four bends, and the bend near the air outlet is higher than the bend near the air inlet. In addition, in practical implementation, besides setting the heat dissipation channel 13 in a stepped configuration, it can also be serpentine. With a stepped heat dissipation channel 13, when the sensor is tilted or when it is continuously exposed to a strong wind, rainwater will flow into the sensor sequentially along the steps. However, the serpentine distribution of the heat dissipation channel 13 creates vertical bends, meaning there are significant bending points within the channel. Therefore, even with strong winds, it is difficult for rainwater to continuously enter the heat dissipation channel 13; some of the rainwater will be trapped at the serpentine bends. This ensures the heat dissipation effect of the heat dissipation channel 13 in high-temperature weather while preventing rainwater from entering the sensor through the heat dissipation channel 13.

[0037] It should be noted that the heat dissipation channels 13 on the base plate 11 can be generated by 3D printing, but 3D printing is costly and inefficient. Alternatively, they can be generated by injection molding. This involves first preparing multiple heat dissipation pipes, then fixing them in an injection mold, and finally injection molding the base plate 11 to generate the required heat dissipation channels 13 on the base plate 11.

[0038] Specifically, the air outlet of a heat dissipation channel 13 is located above the air inlet of an adjacent heat dissipation channel 13, so that the trajectory of multiple heat dissipation channels 13 arranged sequentially forms a closed pattern with an outer C-shape and an inner serpentine shape. In specific implementation, to ensure heat dissipation effect, a sufficient number of heat dissipation channels 13 need to be set, that is, the discharge of the air inlet and outlet of the heat dissipation channel 13 needs to be no less than the number of simply set vertical heat dissipation holes. Therefore, in specific implementation, the trajectory of the heat dissipation channels 13 is arranged sequentially from one end to the other end, so that the air outlet of a heat dissipation channel 13 is located above the air inlet of an adjacent heat dissipation channel 13. After the C-shaped distribution is completed, there is a gap at the top of the air inlet of the heat dissipation channel 13 at the starting point, and there is no corresponding air outlet of another heat dissipation channel 13. Then, the subsequent inner heat dissipation channels 13 are distributed along the serpentine trajectory, so that the air outlet of the current heat dissipation channel 13 is located above the air inlet of the next heat dissipation channel 13, until it coincides with the trajectory of the heat dissipation channel 13 at the starting point. By setting the heat dissipation channel 13 in a reasonable position, the number of air inlets and outlets corresponding to the heat dissipation channel 13 is not less than the number of vertical heat dissipation holes, thereby ensuring the heat dissipation efficiency of the heat dissipation channel 13.

[0039] Additionally, the housing 10 includes a base plate 11 and multiple side plates 12 disposed on the base plate 11. The base plate 11 is located on the fixed side, and the base plate 11 and the side plates 12 enclose a space for accommodating the sensor module. The base plate 11 has multiple heat dissipation channels 13, and a surrounding plate 14 is provided below the base plate 11. Fixing plates 15 are provided on both sides of the surrounding plate 14, and fixing holes 16 are provided on the fixing plates 15. In specific implementations, there may be situations where the sensor is not vertically installed, that is, the base plate 11 may not be directly facing the ground. Therefore, in order to further prevent rainwater from entering the sensor, a surrounding plate 14 of a certain height is set below the base plate 11 to protect the base plate 11 and increase the difficulty of rainwater entry. In addition, the sensor is fixed in the preset installation position by fasteners engaging with the fixing holes 16 on the fixing plates 15 outside the surrounding plate 14. Alternatively, straps can be installed on the mounting plate 15 to fix the sensor, or a magnetic structure or magnet can be installed according to the installation location requirements to fix the sensor to a metal part inside or outside the building.

[0040] Specifically, the sensor housing also includes a cover plate 20, which is located above the housing 10 to close the opening at the top of the housing 10. The cover plate 20 has a first protrusion 21 and a second protrusion 22 extending outward from the bottom outer side and the middle part, respectively. The groove 121 formed between the first protrusion 21 and the second protrusion 22 is adapted to the side plate 12. A limiting block 23 is provided on the inner side of the first protrusion 21. The groove 121 adapted to the limiting block 23 is provided on the outer side of the side plate 12. A sealing groove 24 is provided on the outer side of the second protrusion 22. A sealing ring 30 is provided in the sealing groove 24. A sealing groove 24 is also provided on the inner side of the side plate 12. The two sealing grooves 24 are adapted to each other.

[0041] In addition, the heat dissipation channel 13 is equipped with multiple layers of filters, and a drying element is installed between adjacent filters. In specific implementation, multiple layers of filters can be installed in the heat dissipation channel 13, and a drying element such as activated carbon can be installed between the filters. The filters isolate dust to improve the service life of the sensor, and the drying element absorbs moisture to avoid a continuously humid environment that would reduce the service life of the sensor.

[0042] Specifically, the housing 10 also includes a battery compartment 17. The side plate 12 has an opening to connect the battery compartment 17 to the outside. A sealing plate 18 is provided at the opening. One side of the sealing plate 18 has a limiting rod 181 and a sealing groove 24. The side plate 12 has a limiting groove 122 that matches the limiting rod 181 and a sealing groove 24. The two sealing grooves 24 are mutually compatible, and a sealing ring 30 is provided within each sealing groove 24. Furthermore, in practical implementation, by separately configuring the battery compartment 17, the sensor's battery is easily replaceable, avoiding the need to completely disassemble the sensor for battery replacement, which is cumbersome, involves multiple disassemblies, and affects the sealing effect between the cover plate 20 and the housing 10.

[0043] Additionally, the top of the cover plate 20 is provided with a window 25, which is made of a transparent material. In practical implementation, by providing a transparent window 25, the status of the indicator lights inside the sensor can be observed through the window 25, which facilitates the judgment of the sensor's condition and the identification of problems when the sensor malfunctions, thereby facilitating maintenance.

[0044] In summary, the sensor housing in the above embodiments of this utility model, through the cooperation of the housing 10 and the bottom plate 11 and side plate 12 of the cover plate 20, forms a relatively enclosed accommodating space for the installation and protection of the sensor's electronic components. Furthermore, by providing a heat dissipation channel 13 on the bottom plate 11, the accommodating space can communicate with the outside, thereby improving the sensor's heat dissipation effect. Since the heat dissipation channel 13 is located at the bottom, the probability of rainwater entering the sensor is reduced. In addition, the air inlet and outlet of the heat dissipation channel 13 are staggered, resulting in a longer channel length and a path that is not vertical but inclined, curved, or irregular. This ensures that even if some rainwater enters the heat dissipation channel 13 under the action of airflow, it will collide with the inner wall or bends of the channel 13, slowing down or stopping, and then flowing back out through the air outlet under gravity. Thus, through the structural design and positional distribution of the heat dissipation channel 13, the function of preventing rainwater from entering is achieved while ensuring the heat dissipation effect inside the sensor. Therefore, this utility model solves the problem of insufficient heat dissipation effect of sensor housings in the prior art.

[0045] Furthermore, this utility model also provides a building data acquisition sensor, which includes the aforementioned sensor housing and a sensor module disposed within the sensor housing. The sensor module can be one or more of an accelerometer, strain sensor, temperature sensor, and humidity sensor, or an integrated unit component with acceleration, strain, temperature, and humidity acquisition functions.
