Description

Technical Field

[0001] The utility model relates to the field of inspection equipment, in particular to a battery inspection instrument housing. Background Art

[0002] Battery logging devices, also known as battery logging devices, are specialized monitoring and management systems developed for various types of UPS power systems and battery systems (such as 2V, 6V, and 12V valve-regulated lead-acid batteries). They are widely used in the management of power storage batteries in related industries such as electricity, communications, petrochemicals, finance, railways, transportation, and automobiles. Battery logging devices can be used for voltage monitoring, current monitoring, temperature monitoring, and capacity estimation. They are widely used in places where real-time battery monitoring and management are required, such as power plants, substations, data centers, and communication base stations. In these scenarios, batteries serve as backup power sources or energy storage devices, and their performance and stability are directly related to the safe and stable operation of the entire system.

[0003] A Chinese patent (publication number CN218383218U) discloses a battery inspection instrument with stable heat dissipation. The instrument is provided with an air outlet, an air inlet, and a fan. The two fans located at the air outlet and the air inlet, respectively, discharge and inlet air, thereby facilitating a rapid exchange of hot air within the housing with cold air outside. This results in high heat dissipation stability and good heat dissipation effects. When cleaning the filter, the pull rod is pulled outward, which drives the movable ring to move outward. The movable ring drives multiple limit rods to squeeze the spring and then slide out of the limit groove. The multiple limit rods are no longer engaged with the limit groove, allowing the movable ring and filter to be removed for cleaning. This saves time, effort, and is highly efficient. The sealing ring allows the movable ring to press tightly against the circular groove. The size of the fan is adapted to the size of the air inlet and outlet. Although it increases the effect of active cooling, when the fan is not working, the air inlet and outlet are also affected by the stopped fan, and the air circulation is hindered, affecting its passive heat dissipation effect; the filter is matched with the air outlet and air inlet by the spherical surface at the end of the limit rod and the abutment of the limit groove, which is convenient for disassembly, but its seismic performance is poor, and it is easy to fall off due to vibration during the transportation and adjustment of the battery inspection instrument. The stability of the filter is difficult to meet the needs of frequent changes in the detection position. Utility Model Content

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0028] like Figure 1-Figure 5 As shown, the battery inspection meter housing adjusts the filter 42 and the fan 53 so that the ventilation area corresponding to the filter 42 is larger than the shielding area of ​​the fan 53, thereby ensuring the active and passive heat dissipation performance of the fan 53, solving the heat dissipation problem generated during the operation of the inspection meter, and ensuring the stability and reliability of key components such as the filter 42.

[0029] See also Figure 1 The main structure of the battery inspection instrument shell is a shell 1. Ventilation holes 6 are respectively opened on both sides of the shell 1. A filter 42 is arranged in the ventilation hole 6. The ventilation hole 6 allows air circulation to help dissipate heat; the filter 42 prevents dust, insects, etc. from entering the interior of the shell 1, protecting the internal components from pollution and damage.

[0030] The filter 42 needs to be installed firmly to prevent it from loosening or falling off due to vibration during the operation of the inspection instrument. For this purpose, a positioning groove 7 connected to the ventilation hole 6 is provided on the side of the shell 1, and a positioning hole 8 is provided in the positioning groove 7. The side of the filter 42 extends into the positioning groove 7 to form a positioning block 43. Through the cooperation of the positioning groove 7 and the positioning block 43, a stable installation foundation is provided for the filter 42, reducing the risk of loosening due to vibration.

[0031] The traditional snap-on connection method is not stable enough, especially in a vibrating environment. To this end, in this embodiment, the positioning block 43 is slidably matched with a positioning member 45, and a positioning pin 453 that can be inserted into the positioning hole 8 is formed at one end of the positioning member 45. An anti-slip handle 455 is connected to the positioning member 45, and the anti-slip handle 455 can press or disengage from the positioning block 43 to lock or unlock the relative position of the positioning member 45 and the positioning block 43; the filter screen 42 can be quickly installed and disassembled, and the stability of the installation of the filter screen 42 is enhanced by the pressing effect of the anti-slip handle 455, which effectively resists loosening caused by vibration.

[0032] A fan 53 is provided in the housing 1 at a position corresponding to the ventilation hole 6. The projected area of ​​the fan 53 blades on the filter 42 is smaller than the area of ​​the filter 42. This ensures that when the fan 53 is operating, its blades do not completely block the filter 42, thereby maintaining good air circulation efficiency. When the fan 53 is not operating, it also improves the passive cooling effect in the housing 1.

[0033] like Figure 2 As shown, positioning slots 7 are formed on the side of the housing 1 above and below the ventilation holes 6, and positioning blocks 43 are formed on the upper and lower sides of the filter 42. This enhances the stability of the connection between the filter 42 and the housing 1, and reduces the risk of loosening due to uneven force at a single point through multi-point positioning.

[0034] Positioning members 45 are mounted on both ends of the positioning block 43, and the positioning members 45 correspond one-to-one with the positioning holes 8 in the positioning groove 7. The double-end installation further improves the stability of the installation of the filter screen 42, and can maintain a stable connection even in a vibration environment.

[0035] like Figure 3 and Figure 4 As shown, positioning member 45 includes a positioning pin 453, a movable block 451, and a spring 452. The movable block 451 has a through slot 46, through which the positioning pin 453 can extend or retract. The spring 452 abuts against the positioning block 43 and compresses and rebounds in the sliding direction. The compression and rebound of the spring 452 provide additional stability and cushioning for positioning, ensuring that the positioning pin 453 remains within the positioning hole 8 in the locked state.

[0036] The positioning member 45 and the filter screen 42 constitute the protective body 4 , and the fan 53 and the supporting structure on which the fan 53 is installed on the housing 1 constitute the heat dissipation body 5 .

[0037] The anti-slip handle 455 is provided with a guide post 454. The movable block 451 has a threaded hole. The guide post 454 passes through the movable slot 44 and engages with the threaded hole to achieve compression or disengagement. Through the threaded connection, during the rotation of the anti-slip handle 455, one end of the anti-slip handle 455 can gradually abut and press against the positioning block 43, so that the anti-slip handle 455 can firmly lock the positioning member 45, preventing accidental loosening or falling off due to vibration, while facilitating user installation and removal operations.

[0038] The movable block 451 is equipped with two parallel springs 452. The double spring 452 design further enhances the stability of the positioning member 45, so that the filter screen 42 can maintain a better fixing effect when subjected to vibration.

[0039] like Figure 5As shown, the fan 53 is installed on the shell 1 through the support plate 51 and the support rod 52. The fan 53, the support plate 51 and the support rod 52 together constitute the protective body 4. The fan 53 is installed on the support plate 51, and the support plate 51 is fixed to the shell 1 through the support rod 52. The fan 53 is provided with blades, and the blades drive the airflow through rotation, promote the cooling of the airflow inside the inspection instrument shell 1, provide a stable support for the fan 53, and reduce the impact of the vibration of the fan 53 on other components inside the shell 1.

[0040] The area of ​​the ventilation holes 6 is larger than half of the area of ​​the side surface of the housing 1. The large area of ​​the ventilation holes 6 improves the air circulation efficiency, helps to better dissipate heat, and ensures the air circulation inside the housing 1.

[0041] like Figure 1 and Figure 2 As shown, the filter 42 is rectangular, with the outer ring being the mounting frame 41, which is a rectangular frame-like structure. The filter is held in tension by the mounting frame 41. The vents 6 are rectangular holes, with fans 53 on either side. The rectangular design facilitates the installation and positioning of the filter 42 and the vents 6. The fan 53 is located between the filter 42, ensuring that air can pass through the filter 42 smoothly and be dispersed by the fan 53, thereby improving the heat dissipation effect.

[0042] Start the fans 53 on both sides of the shell 1. The two fans 53 exhaust and inhale air respectively, which can quickly exchange the hot air in the shell 1 with the external cold air, with fast heat dissipation speed, high heat dissipation stability and good effect.

[0043] like Figure 1 As shown, a display screen 2 and control buttons 3 are installed on the housing 1. As additional components of the housing 1, they provide the user with an intuitive operation interface and status display, making it easy for the user to monitor the working status of the inspection instrument and make necessary operational adjustments.

[0044] During use, by setting ventilation holes 6 on the left and right sides of the shell 1, respectively for air intake and air outlet, and then starting the fans 53 on both sides of the shell 1, the two fans 53 are respectively used for air outlet and air intake, which can quickly exchange the hot air in the shell 1 with the external cold air, with fast heat dissipation speed, high heat dissipation stability and good effect. By setting the positioning member 45, when the filter 42 needs to be cleaned, the two anti-slip handles 455 on the same side are squeezed, and the two anti-slip handles 455 are brought close to each other to make the guide column 454 slide in the through groove 46, and the spring 452 is used to compress the filter 42. The movable block 451 slides in the movable groove 44, thereby moving the positioning pin 453 out of the positioning hole 8 and storing it in the movable groove 44, and then the installation frame 41 can be moved out of the ventilation hole 6, making it convenient to take out the filter screen 42 for cleaning, reducing the labor intensity of the staff. Conversely, the elastic force of the spring 452 is used to push the positioning pin 453 out of the movable groove 44 and snap it into the positioning hole 8, so that the installation frame 41 can be fixedly installed in the ventilation hole 6. It has a simple structure and is easy to operate, which can realize the rapid installation of the protective body 4 and is easy to use.

[0045] The above detailed description of the specific embodiments of the utility model is intended to be illustrative only, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions made to the utility model are also within the scope of the utility model. Therefore, equivalent changes, modifications, and improvements made without departing from the spirit and scope of the principles of the utility model should be included within the scope of the utility model.
