[0048] In the figures, structurally similar elements are denoted by the same reference numerals.

[0049] The utility model provides a waterproof heat dissipation structure, which includes a shell 11, a heat conductive sheet 12 and a heat dissipation fan 13; wherein a transverse partition 111 is arranged inside the shell 11, and the transverse partition 111 divides the inside of the shell 11 into a first cavity 112 and a second cavity 113, the first cavity 112 is located above the second cavity 113, and a camera body is arranged in the first cavity 112; the heat conductive sheet 12 is arranged in the first cavity 112, and the heat conductive sheet 12 connects the camera body with the shell 11; the heat dissipation fan 13 is arranged in the second cavity 113 and is connected to the bottom end of the transverse partition 111, and a first ventilation hole 115 is arranged on the shell 11, and the first ventilation hole 115 is communicated with the second cavity 113.

[0050] The combination of the outer shell 11, the heat conductive sheet 12 and the cooling fan 13 constitutes a waterproof heat dissipation structure. This structure can protect the camera body and the key components inside from water intrusion and damage. In a humid or underwater environment, the waterproof heat dissipation structure can ensure the normal operation of the camera and extend the service life of the camera. The diaphragm 111 in the waterproof heat dissipation structure separates the interior of the outer shell 11 into a first cavity 112 and a second cavity 113. The heat conductive sheet 12 is arranged in the first cavity 112 and connected to the outer shell 11, and can quickly conduct the heat generated in the first cavity 112 to the outer shell 11 to achieve heat dissipation. The cooling fan 13 is arranged in the second cavity 113 and connected to the diaphragm 111, and can discharge hot air through the ventilation holes to increase the heat dissipation effect.

[0051] The waterproof heat dissipation structure in this embodiment is described in detail as follows:

[0052] Combination Figure 3 The waterproof heat dissipation structure in this embodiment also includes a heat sink 14, which is arranged inside the second cavity 113. The heat sink 14 is connected to the bottom end of the partition 111. The heat sink 14 increases the heat dissipation area of ​​the partition 111, making it easier for the partition 111 to quickly remove the heat from the heat conductive sheet 12.

[0053] Combination Figure 4 and Figure 5 , the structure of the heat conducting sheet 12 in this embodiment is described in detail:

[0054] The heat conductive sheet 12 in this embodiment includes a first end 121 and a second end 122; the first end 121 is vertically arranged on one side of the camera body, one side of the first end 121 is connected to the inner wall of the outer shell 11, and the other side of the first end 121 is in contact with the camera body; the second end 122 is connected to the top surface of the partition 111, and the second end 122 is located between the partition 111 and the camera body.

[0055] The heat conducting sheet 12 is in contact with the camera body and the housing 11 through the first end 121, and can effectively conduct heat, and quickly transfer the heat generated by the camera to the housing 11 to achieve rapid heat dissipation. The second end 122 is set to transfer heat from the camera body to the diaphragm 111, further optimize the distribution of heat, increase the heat dissipation area of ​​the heat conducting sheet 12 and the housing 11, make more surfaces contact with the environment, and enhance the heat dissipation effect.

[0056] In addition, the camera body includes a lens device 21, and a first avoidance notch 1211 is provided on one side of the top of the heat conductive sheet 12, and the first avoidance notch 1211 is located on the side of the lens device 21. The design of the first avoidance notch 1211 of the heat conductive sheet 12 can ensure that the normal function of the lens device 21 is not interfered with; since the heat conductive sheet 12 is separated from the side of the lens by a certain distance, the heat conductive sheet 12 will not block or hinder the camera lens, and will not affect the imaging quality and user experience of the camera. By providing the first avoidance notch 1211, the heat conductive sheet 12 can be more closely attached to the camera body, ensuring the stability of the heat conductive sheet 12 during the assembly process.

[0057] In this embodiment, a positioning column 114 is provided on the inner side of the shell 11, and a positioning groove 1212 is provided on the first end 121. The positioning column 114 is plugged into the positioning groove 1212 to prevent the heat conducting plate 12 from shaking in the shell 11, and the heat conducting plate 12 can be more easily installed and disassembled, which is convenient for maintenance and replacement.

[0058] The second end portion 122 is provided with a connecting hole 1221, and the top of the transverse partition 111 is provided with a mounting hole. The second end portion 122 is screwed through the connecting hole 1221 and connected to the mounting hole, which facilitates the installation of the heat conducting plate 12 and improves the stability of the connection between the heat conducting plate 12 and the transverse partition 111.

[0059] The second end 122 is provided with a second avoidance notch 1222, and the second avoidance notch 1222 is used to avoid the heat dissipation fan 13. The second avoidance notch 1222 of the heat conductive sheet 12 can better cooperate with the heat dissipation fan 13 and optimize the layout of the overall heat dissipation system. The second avoidance notch 1222 ensures that there is enough space between the heat conductive sheet 12 and the heat dissipation fan 13 to avoid interference and conflict, so that the two can work together to improve the heat dissipation effect.

[0060] The heat conducting sheet 12 is provided with a third through hole 1213, and the third through hole 1213 is used to avoid the data port. The provision of the third through hole 1213 can prevent the heat conducting sheet 12 from directly covering or blocking the data port. This can prevent the heat conducting sheet 12 from interfering with data transmission and protect the stability and reliability of the data port. It can prevent the data port from being damaged or degraded due to heat. The user can more easily connect or disconnect the data cable, insert or remove external devices such as a memory card, without removing the entire heat conducting sheet 12. This facilitates data management and operation and improves the user's convenience.

[0061] In this embodiment, an assembly groove 116 is provided on the inner wall of the housing 11 , and the first end portion 121 of the heat conducting sheet 12 is received in the assembly groove 116 , thereby improving the stability of the connection between the heat conducting sheet 12 and the housing 11 .

[0062] The structure of the cooling fan 13 in this embodiment is described as follows:

[0064] The cooling fan 13 in this embodiment connects the fan blades 133 to the outer side of the fan housing 131 through the rotor 132, and the stator 134 is arranged inside the fan housing 131. The stator 134 is used to generate magnetic force to drive the rotor 132 to rotate when powered on. The cooling fan 13 in this application is physically separated by the fan housing 131 to completely separate the fan blades 133 and the stator 134 that drives the fan blades 133 to rotate, thereby achieving deep waterproofing of the cooling fan 13, improving the sealing of the first cavity 112 for installing the camera body, and achieving waterproofness of the heat dissipation structure.

[0065] Combination Figure 6 and Figure 7The fan housing 131 is also connected to an air guide cover 137. The air guide cover 137 is provided with a second ventilation hole 1371 at one end away from the stator 134. The side of the air guide cover 137 is provided with a third ventilation hole 1372. The second ventilation hole 1371 is connected to the third ventilation hole 1372. The air guide cover 137 guides and transports the wind. The heat dissipation fan 13 in this embodiment takes in the wind from the second ventilation hole 1371 and discharges the wind from the third ventilation hole 1372.

[0066] The third ventilation hole 1372 in this embodiment faces one side of the heat sink 14, thereby improving the heat dissipation efficiency of the waterproof heat dissipation structure.

[0067] Preferably, the air guide cover 137 in this embodiment is connected to the fan housing 131 by screws, and the structure is compact and stable, which is convenient for the assembly and use of the heat dissipation fan 13. A second accommodating cavity is formed between the inside of the air guide cover 137 and the outer ring of the fan housing 131, and the second accommodating cavity is used to accommodate the fan blades 133 to avoid collision loss of the fan blades 133 and improve the stability of the overall structure of the heat dissipation fan 13. The air guide cover 137 and the fan housing 131 in this embodiment can also be connected by common welding, riveting or threaded structures, which will not be described in detail here.

[0068] Furthermore, the aperture of the second ventilation hole 1371 is smaller than the rotation diameter of the blade 133, which prevents the blade 133 from falling off and improves the compactness of the structure of the cooling fan 13. The aperture of the third ventilation hole 1372 is smaller than the rotation diameter of the blade 133, which prevents the blade 133 from falling off from the wind guide cover 137.

[0069] The heat dissipation fan 13 in this embodiment also includes a driving circuit board 135, which is installed in the first accommodation cavity 1311.

Furthermore, a first limiting groove is provided on the outer side of the positioning protrusion 1312, and the sealing ring 136 is installed in the first limiting groove to improve the stability of the connection between the sealing ring 136 and the positioning protrusion 1312.

[0071] A second limiting groove 1313 is further provided on the outer side of the fan housing 131 of the heat dissipation fan 13 in this embodiment. The second limiting groove 1313 can cooperate with the sealing member to further seal the connection between the heat dissipation fan 13 and the transverse partition 111, thereby improving the sealing performance of the waterproof heat dissipation structure.

Compared with the traditional fan structure, the fan blade 133 of the present application not only fully utilizes the space in the second accommodating cavity, improves the compactness of the heat dissipation fan 13 structure, and reduces the volume of the heat dissipation fan 13; it also reduces the rotational torque of the rotor 132 driving the fan blade 133, making it easier for the rotor 132 to drive the fan blade 133 to rotate, making it easier to drive the fan blade 133.

[0075] Furthermore, in this embodiment, the connecting plate 1333 is arranged on the peripheral side of the fixing plate 1331, and the connecting plate 1333 is a connecting cylinder, which is sleeved on the outer ring of the fan housing 131.

[0077] Furthermore, a support protrusion 13311 is provided on the side of the connecting plate 1333 away from the stator 134, and the support protrusion 13311 is in contact with the rotor 132. In this embodiment, the support protrusion 13311 is in contact with the inner ring of the top end of the sleeve, and the support protrusion 13311 separates the bottom surface of the fixing plate 1331 from the top surface of the fan housing 131.

The cooling fan 13 is arranged in the second cavity 113 and connected to the diaphragm 111, and can discharge hot air through the first ventilation hole 115 to increase the heat dissipation effect.

[0082] The camera body is located in the first cavity 112, including a lens device 21, a display device 22, a battery device 23 and a circuit board device 24. One end of the heat conductive sheet 12 is located between the circuit board device 24 and the housing 11, which can quickly conduct the heat generated by the circuit board to the housing 11 to prevent the circuit board from malfunctioning or performance degradation due to overheating. The connection between the lens device 21, the display device 22 and the battery device 23 and the circuit board device 24 also helps to maintain a stable working state of the camera. The design of the heat conductive sheet 12 in this embodiment can also be extended to the top of the partition 111 by bending the other end to achieve uniform distribution of heat. This can avoid heat accumulation and hot spot formation, maintain the temperature balance inside the entire camera, improve the heat dissipation effect, and reduce the impact of temperature on camera performance.

[0083] The structure of the waterproof heat dissipation structure in this embodiment is the same as the waterproof heat dissipation structure described in the above embodiments, and other structures are not repeated here.

[0084] The working principle of the waterproof heat dissipation structure of the utility model and the panoramic camera using the same:

[0085] 1. The first end 121 of the heat conductive sheet 12 is located between the circuit board device 24 and the housing 11, and can quickly conduct the heat generated by the circuit board to the housing 11, thereby preventing the circuit board from malfunctioning or degrading due to overheating. The connection between the lens device 21, the display device 22, and the battery device 23 and the circuit board device 24 also helps to maintain a stable working state of the camera. The second end 122 of the heat conductive sheet 12 is bent and extended to the top of the partition 111, thereby achieving uniform distribution of heat. This can avoid heat accumulation and hot spot formation, maintain the temperature balance inside the entire camera, improve the heat dissipation effect, and reduce the impact of temperature on camera performance.

[0086] 2. The heat sink 14 increases the heat dissipation area of ​​the transverse partition 111, making it easier for the transverse partition 111 to quickly dissipate the heat of the heat conducting sheet 12.

[0087] 3. During the use of the heat dissipation fan 13, the power switch of the stator 134 is controlled by the driving circuit board 135. When the stator 134 is powered on, a magnetic field is generated, and the magnetic drive rotor 132 rotates; thereby the rotor 132 drives the fan blades 133 to rotate, so that air enters from the second ventilation hole 1371 of the air guide cover 137 and then is discharged from the third ventilation hole 1372. In this embodiment, the third ventilation hole 1372 faces the side of the heat sink 14, which improves the heat dissipation efficiency of the waterproof heat dissipation structure.

[0088] This completes the working process of the waterproof heat dissipation structure of this preferred embodiment.

[0089] The cooling fan 13 in this embodiment completely separates the fan blades 133 and the rotor 132 from the stator 134 and the driving circuit board 135 through the fan housing 131, so that the rotating part and the electric drive part of the cooling fan 13 are separated, and the electric drive part is sealed in the housing, so that the cooling fan 13 can be waterproof.

[0090] The connection between the driving circuit board 135 and the stator 134 and other controllers in this embodiment is a common circuit connection, and the connection method is commonly used in industrial automatic control, which will not be described in detail here.

[0091] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
