Description

Technical Field

[0001] This utility model relates to the field of battery camera technology, specifically to an AOV4G battery camera with battery overheat protection. Background Technology

[0002] Battery-powered cameras are video surveillance cameras with built-in batteries. They are assembled in different working positions according to different application scenarios and types. They are flexible to install and have good concealment. They are relatively independent and stable in use and can adapt to harsh environments. However, their battery life is limited and it is not convenient to improve their performance.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN202022667238.3, filed on 2020-11-17) provides a battery camera that can accurately determine the weight of the material in the feed cylinder through a weighing module. Baffles extending along the front and back sides are provided at the center of both sides of the bracket, and these baffles are elastic, effectively securing the battery and allowing the camera assembly to operate effectively. A rubber ring is provided at the back edge of the front shell, which, in conjunction with a first groove on the edge of the rear shell, forms a ring. This allows the rubber ring to engage with the first groove, improving the connection between the front and rear shells and ensuring the device is sealed, preventing rust within the device and affecting working efficiency.

[0004] While existing technologies can achieve heat dissipation and improve battery life, the battery is prone to overheating during prolonged operation, which can affect working efficiency and stability.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing battery-powered cameras. Utility Model Content

[0006] The purpose of this invention is to provide an AOV4G battery camera with battery overheat protection, in order to solve the problem mentioned in the background art that the battery is prone to overheating during operation, which affects the working efficiency and stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an AOV4G battery camera with battery overheat protection, comprising a battery camera body for easy assembly, and a camera mounted on the front end of the battery camera body; including: a battery bracket nested inside the battery camera body, with the battery body nested and connected to the inner surface of the battery bracket, and the battery bracket having a wind-powered heat dissipation mechanism; a cooling channel opened inside the battery bracket, with a drain pipe installed on the upper surface of the battery bracket, and the drain pipe having a circulating heat dissipation mechanism; and a heat-absorbing component attached to the front side of the outer surface of the battery bracket, and the heat-absorbing component having a linkage opening and closing mechanism.

[0008] Preferably, the wind-powered heat dissipation mechanism includes a heat dissipation grease attached to the upper surface of the battery bracket, a heat dissipation fin attached to the upper surface of the heat dissipation grease, a brushless fan attached to the upper surface of the heat dissipation fin, an air intake component attached to the outer side of the heat dissipation fin, and the air intake component is nested in the side wall of the battery camera body. At the same time, an exhaust component is attached to the upper surface of the brushless fan, and the outer sides of the exhaust component are nested in the side wall of the battery camera body.

[0009] With the above structure, it is easy to effectively cool down the air by combining air intake and exhaust, and by transferring temperature through air cooling.

[0010] Preferably, the battery bracket is fitted with a heat dissipation grease and a heat dissipation fin, and the heat dissipation fin is fitted with a brushless fan to form a heat dissipation structure. The heat dissipation fin is fitted with the battery camera body through an air intake component to form a nested air intake structure, and the brushless fan is fitted with the battery camera body through an exhaust component to form a nested air exhaust structure.

[0011] With the above structure, it is easy to transfer heat effectively through thermal grease and cool down by airflow during use.

[0012] Preferably, the circulating heat dissipation mechanism includes a circulating pipe installed on the outer surface of the drain pipe, and heat dissipation fins are nested on the outer surface of the circulating pipe. An inlet pipe is installed at the other end of the circulating pipe, and the lower side of the inlet pipe is installed on the upper surface of the battery bracket.

[0013] With the above structure, the rotating tube can be effectively assembled during use, and it can be combined with the cooling channel to improve the circulation of heated liquid and enhance the cooling effect in conjunction with the airflow.

[0014] Preferably, the cooling channels are arranged at equal intervals inside the battery bracket, and the battery bracket forms an integrated structure with the drain pipe through the cooling channels, and the battery bracket forms a liquid circulation structure through the drain pipe, circulation pipe and inlet pipe.

[0015] The above structure improves heat transfer during use and, in conjunction with air cooling, enhances the overheat protection of the battery body.

[0016] Preferably, the linkage opening and closing mechanism includes a liquid inlet pipe II mounted on the outer surface of the heat absorption component, and an expansion air bladder mounted on the outer surface of the liquid inlet pipe II. The expansion air bladder is nested in the inner surface of the air intake component, and a squeezing component is attached to the lower surface of the expansion air bladder. A return spring is elastically connected between the squeezing component and the air intake component. A side rod is mounted on the lower surface of the squeezing component, and a connecting rod is rotatably connected to the inner surface of the side rod. An air intake plate is rotatably connected to the lower side of the outer surface of the connecting rod, and the air intake plate is rotatably connected to the inner side surface of the air intake component.

[0017] With the above structure, the assembly of the inflatable airbag and the position of the side rod can be controlled during use. This allows for the control of the opening of the air intake plate on the air intake component and the holes set on the air intake plate according to the heat dissipation requirements, without affecting the requirements of individual wind power heat dissipation.

The extrusion component and the air inlet component form an elastic sliding structure via a return spring. At the same time, the extrusion component and the air inlet plate form an extrusion positioning and flipping structure via a side rod and a connecting rod.

[0019] The above structure improves heat absorption while controlling air intake and dissipating heat from the battery body during use.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The AOV4G battery camera with battery overheat protection is equipped with a battery bracket and battery body for easy nesting and assembly. It is equipped with air intake and exhaust components and a brushless fan for air cooling. It also uses a cooling channel and circulation pipe in conjunction with heat dissipation fins to form a heat transfer and air cooling liquid cooling treatment. The air intake plate at the air intake component controls the air cooling intake volume.

[0022] 2. This AOV4G battery-powered camera with battery overheat protection is equipped with a wind-powered cooling mechanism. The air intake mounted on the side of the battery bracket, along with the brushless motor and exhaust mounted on the heat dissipation fins, provides wind-powered rotation and air cooling. The holes in the air intake plate connected to the intake do not affect the direct air cooling effect. Furthermore, the circulating cooling mechanism, through the cooling channels and drain pipes in the battery body, and the assembled circulating pipe and inlet pipe, combined with the heat dissipation fins nested in the circulating pipe, controls heat transfer and, in conjunction with air cooling, provides sufficient cooling, thus protecting the battery body from overheating.

[0023] 3. The AOV4G battery camera with battery overheat protection is equipped with a linkage opening and closing mechanism. When the battery body generates heat during operation, the material inside the heat-absorbing component is heated and expanded. The expansion airbag is controlled to push the extrusion component downward, thereby controlling the connecting rod of the side rod assembly to drive the air intake plate to rotate in a positioning manner. This controls the air intake volume according to the amount of heat transfer and improves the cooling effect, preventing excessive external impurities from entering the battery camera body. Furthermore, the expansion airbag, through the reset spring between the extrusion component and the air intake component, can control the extrusion component to reset after the battery body temperature drops.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6The present invention provides the following technical solution: an AOV4G battery camera with battery overheat protection, which is provided with a battery camera body 1 for easy assembly, and a camera 2 is assembled at the front end of the battery camera body 1.

[0033] Example 1: As Figures 1-3 The technical solution shown is provided by this utility model as follows: An AOV4G battery camera with battery overheat protection is disclosed, comprising: a battery bracket 3, nested inside the battery camera body 1, with a battery body 4 nested and connected to the inner surface of the battery bracket 3, and the battery bracket 3 is provided with a wind-powered heat dissipation mechanism; the wind-powered heat dissipation mechanism includes a thermal grease 5 attached to the upper surface of the battery bracket 3, a heat dissipation tab 6 attached to the upper surface of the thermal grease 5, and a brushless fan 7 connected to the upper surface of the heat dissipation tab 6, while the heat dissipation tab 6... An air intake component 8 is connected to the outer surface side of the battery camera body 1 and is nested in the side wall of the battery camera body 1. At the same time, an exhaust component 9 is connected to the upper surface of the brushless fan 7 and the outer surfaces of the exhaust component 9 are nested in the side wall of the battery camera body 1. The battery bracket 3 forms a bonding structure with the heat dissipation fins 6 through the heat dissipation grease 5. The heat dissipation fins 6 form a heat dissipation structure through the brushless fan 7. The heat dissipation fins 6 form a nested air intake structure with the battery camera body 1 through the air intake component 8. At the same time, the brushless fan 7 forms a nested air exhaust structure with the battery camera body 1 through the exhaust component 9.

[0034] In use, the camera 2 is stably mounted on the battery camera body 1, and the battery camera body 1 is assembled in the working position. The battery body 4, which is mounted on the battery bracket 3, is nested on the inner surface of the battery camera body 1 for power supply. When the battery body 4 is working, the heat dissipation grease 5 connected to the upper side of the battery bracket 3 absorbs heat and transfers the heat to the heat dissipation fins 6 through the heat dissipation grease 5. The brushless fan 7 is started to rotate. With the rotation of the brushless fan 7, the air force is controlled to enter through the air intake 8 nested in the battery camera body 1 and the holes opened in the air intake 8. The air force is delivered to the heat dissipation fins 6 and then output through the brushless fan 7 on the heat dissipation fins 6 to the exhaust fins 9. The air is discharged from the openings on both sides of the exhaust fins 9, thereby performing effective air cooling and improving the overheat protection effect of the battery body 4 and dealing with the initial heat generation in a timely manner.

[0035] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4The technical solution shown, based on Embodiment 1, further discloses a liquid cooling operation that achieves sufficient cooling on top of air cooling. The specific details are as follows: a cooling channel 10 is located inside the battery bracket 3, and a drain pipe 11 is installed on the upper surface of the battery bracket 3. The drain pipe 11 is equipped with a circulating heat dissipation mechanism. The circulating heat dissipation mechanism includes a circulation pipe 12 installed on the outer surface of the drain pipe 11, and heat dissipation fins 6 are nested on the outer surface of the circulation pipe 12. An inlet pipe 13 is installed at the other end of the circulation pipe 12, and the lower side of the inlet pipe 13 is installed on the upper surface of the battery bracket 3. The cooling channel 10 is equidistant from the inside of the battery bracket 3, and the battery bracket 3 forms an integrated structure with the drain pipe 11 through the cooling channel 10. The battery bracket 3 also forms a liquid circulation structure through the drain pipe 11, the circulation pipe 12, and the inlet pipe 13.

[0036] When the battery body 4 is air-cooled, the liquid in the cooling channel 10 opened by the battery bracket 3 is heated, and the micro pump connected to the liquid inlet pipe 13 assembled by the battery bracket 3 is activated, so that the liquid that has absorbed heat in the cooling channel 10 is transported to the drain pipe 11, and then transported to the circulation pipe 12 in conjunction with the drain pipe 11. The heated liquid in the circulation pipe 12 is cooled by the nested heat dissipation fins 6, and in conjunction with the air cooling, the cooling effect is further improved. After the liquid in the circulation pipe 12 is cooled, it is transported to the battery bracket 3 connected to the liquid inlet pipe 13 assembled by the micro pump, thereby improving the cooling effect of the battery bracket 3.

[0037] Example 3: Figure 1 , Figure 2 , Figure 5 and Figure 6 The technical solution shown, based on Embodiment 2, further discloses the angle adjustment of the air intake plate 21, the specific details of which are as follows: A heat-absorbing component 14 is attached to the front of the outer surface of the battery holder 3, and the heat-absorbing component 14 is provided with a linkage opening and closing mechanism; the linkage opening and closing mechanism includes a liquid inlet pipe 2 15 mounted on the outer surface of the heat-absorbing component 14, and an expansion airbag 16 is mounted on the outer surface of the liquid inlet pipe 2 15, and the expansion airbag 16 is nested within the inner surface of the air intake component 8, and a compression component 17 is attached to the lower surface of the expansion airbag 16, while a return spring 18 is elastically connected between the compression component 17 and the air intake component 8. Furthermore, a side rod 19 is installed on the lower surface of the extrusion member 17, and a connecting rod 20 is rotatably connected to the inner surface of the side rod 19. At the same time, an air inlet plate 21 is rotatably connected to the lower side of the outer surface of the connecting rod 20, and the air inlet plate 21 is rotatably connected to the inner side surface of the air inlet member 8. The heat absorption member 14 is connected to the expansion airbag 16 through the liquid inlet pipe 15, and the expansion airbag 16 and the extrusion member 17 form an expansion extrusion structure. The extrusion member 17 is connected to the air inlet member 8 through the return spring 18, and the extrusion member 17 is connected to the air inlet plate 21 through the side rod 19 and the connecting rod 20, forming an extrusion positioning and flipping structure.

[0038] When the battery body 4 overheats, the heat is transferred to the heat absorber 14, and the liquid inside the heat absorber 14 is heated and expanded. The liquid is then controlled to be transported to the expansion airbag 16 assembled in the liquid inlet pipe 2 15. The expansion airbag 16 pushes the side rod 19 installed on the extrusion member 17 to move downward. The angle of the positioning rotation of the air intake plate 21 is adjusted by the connecting rod 20 assembled on the side rod 19, thereby adjusting the air intake volume and cooling effect of the air intake member 8 and controlling the overheat protection safety of the battery body 4. After the battery body 4 cools down to a certain temperature, the expansion airbag 16 will be controlled to move upward and reset by the extrusion member 17 connected to the reset spring 18, thereby controlling the backflow of the expansion material in the expansion airbag 16, controlling the air intake volume of the air intake member 8, reducing the entry of impurities into the battery camera body 1, and improving the stability of the battery camera body 1 in use.
