Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1 to 10, a high heat dissipation vehicle camera assembly structure includes a first shell 3 and a second shell 4 arranged on one side of a fender 1, a mounting groove 2 is opened on the side of the fender 1 close to the first shell 3, a charging base is installed inside the mounting groove 2, and the charging base is used to provide a power source for the vehicle camera, a camera body 5 is fixedly connected to the side of the second shell 4 away from the first shell 3, four groups of concave plates 6 are fixedly connected to the outer sides of the first shell 3 and the second shell 4, a camera transmitter 7 is fixedly connected to the inner wall of the camera body 5, a hollow rod 8 is fixedly connected to one end of the camera transmitter 7, and a connector 9 is arranged on the end of the hollow rod 8 away from the camera transmitter 7, and also includes;

A disassembly and assembly mechanism is arranged inside the first shell 3, and the disassembly and assembly mechanism is used for quickly installing and disassembling the vehicle-mounted camera. The disassembly and assembly mechanism includes a limit ring 10, and the limit ring 10 is fixedly connected to the outer side of the electrical connector 9. The end of the limit ring 10 away from the electrical connector 9 is fixedly connected to a screw rod 11, and the end away from the electrical connector 9 is slidably connected to the outer side of the hollow rod 8. The outer side of the screw rod 11 is threadedly connected to a guide ring 12, and the outer side of the guide ring 12 is fixedly connected to multiple groups of limit rods 13, and the ends of the multiple groups of limit rods 13 away from the guide ring 12 are fixedly connected to a steering ring 14, and the steering ring 14 is slidably connected to both the first shell 3 and the second shell 4, and the electrical connector 9 and the camera transmitter 7 are electrically connected;

A heat dissipation mechanism is disposed inside the second housing 4, and is used to reduce the heat generated when the vehicle-mounted camera is in operation. The heat dissipation mechanism includes a fixing plate 15, and the fixing plate 15 is fixedly connected to the inner wall of the second housing 4;

A sealing mechanism is arranged inside the first shell 3, and is used to protect the electronic components inside the vehicle-mounted camera. The sealing mechanism includes a first meshing ring 16, and the first meshing ring 16 is fixedly connected to the outer side of the multiple groups of limit rods 13. The end of the first meshing ring 16 away from the camera transmitter 7 is meshed with a second meshing ring 17, and the end of the second meshing ring 17 away from the first meshing ring 16 is fixedly connected to a connecting circular plate 18, and the connecting circular plate 18 is rotatably connected to the inner wall of the first shell 3.

The first housing 3 is installed on the outer fender 1 of the vehicle by bolt connection. When the vehicle needs to use the vehicle-mounted camera, the control end in the vehicle collects external information through the camera body 5, and the obtained data is then transmitted to the vehicle control end through the camera transmitter 7. However, the vehicle-mounted camera will generate a lot of heat when working. If the heat cannot be effectively dissipated, it will affect the performance and life of the camera body 5. In addition, the existing vehicle-mounted camera assembly structure is usually assembled using fasteners such as screws. This method not only has low assembly efficiency, but also the fasteners are easy to loosen or fall off, affecting the stability and service life of the camera body 5. In order to solve the above problems, when the embodiment of the present invention is used, the first housing 3 is first inserted into the installation groove 2 opened inside the fender 1, and then the steering ring 14 is rotated. The rotation of the steering ring 14 drives the guide ring 12 to rotate through the limit rod 13, and the guide ring 12 is meshed with the screw 11. Since the position of the steering ring 14 is fixed, it can only rotate but cannot move. Therefore, during the rotation of the guide ring 12, the screw 11 will be driven toward the electrical connector 9. The first shell 3 is moved in the direction of rotation. At this time, the screw 11 drives the electrical connector 9 to move through the limit ring 10 along the outer side of the hollow rod 8. As the limit ring 10 continues to move, the limit ring 10 will contact and squeeze the disassembly and assembly mechanism. When the limit ring 10 drives the electrical connector 9 to contact the charging base inside the installation groove 2, the charging base can transmit electricity to the camera transmitter 7 through the electrical connector 9 (the camera transmitter 7 is a prior art with mature technology and is used for data transfer transmission in video recording. It will not be introduced in detail in the article). The disassembly and assembly mechanism also limits the first shell 3, so that the first shell 3 cannot move, thereby realizing the function of quickly fixing the camera body 5. Through the above-mentioned structural design, the camera body 5 can be powered on without additional operation during the process of quickly fixing the camera body 5, which improves the convenience of device installation and shortens the working time. When the user starts the power supply and checks the situation outside the vehicle through the camera body 5, the camera transmitter 7 is not only used as a data transfer transmission end, but also can be used for a battery. When the power is turned on, it can provide power to the heat dissipation mechanism. Source, so that its heat dissipation mechanism is started, and air is blown to the camera body 5 when it is started, so as to improve the air circulation inside the camera body 5, thereby achieving the function of heat dissipation, and the inner and outer bodies of the camera body 5 are made of heat-conducting material, and the heat-conducting material is a heat-conducting silicone sheet. Before the vehicle-mounted camera is transported or installed, it is in the outside world and the electronic components inside it are easily affected by moisture, which causes damage to the electronic components and affects the service life of the device. Before use, the interior of the present invention is affected by the sealing mechanism and is in a relatively sealed state, which can effectively solve the above problems. When the steering ring 14 is rotated, the first meshing ring 16 will be driven to rotate through the limiting rod 13, and the rotation of the first meshing ring 16 will drive the second meshing ring 17 to rotate synchronously. The rotation of the second meshing ring 17 will cooperate with the connecting circular plate 18 to make its sealing mechanism operate. The operation of the sealing mechanism will open the center of the connecting circular plate 18, thereby avoiding the situation that the limiting ring 10 drives the electrical connector 9 to move toward the fender 1 and is unable to move due to the sealing mechanism. Through this structural design, it can be achieved before the camera body 5 is installed to ensure a certain degree of sealing inside it. It effectively prevents the internal moisture or external dust and impurities from adhering to the electronic components inside the camera body 5. When the camera body 5 is installed, the sealing mechanism will operate and will not hinder the normal movement of the electrical connector 9, thereby improving the linkage of the device. It should be noted that the structure installed inside the first shell 3, the second shell 4 and the camera body 5 will not hinder the installation of the normal required parts of the vehicle-mounted camera. The vehicle-mounted camera is a prior art with mature technology and will not be introduced in detail in the article. When the camera body 5 is disassembled, it is only necessary to rotate the steering ring 14 in the opposite direction. The reverse rotation of the steering ring 14 will eventually drive the electrical connector 9 to reset. The reset of the electrical connector 9 will disconnect the power supply to the camera transmitter 7. The camera body 5 does not need to work at this time, and the power supply of the camera transmitter 7 to the heat dissipation mechanism is terminated, and the heat dissipation mechanism will stop running. During the reset of the electrical connector 9, the sealing mechanism is also in a reset state. When the electrical connector 9 is completely reset, the sealing mechanism is also completely reset, and the interior of the camera body 5 is sealed again, thereby playing a moisture-proof and dust-proof function.

As shown in Figures 3 and 4, the disassembly and assembly mechanism also includes a pair of L-shaped plates 19 that are symmetrically distributed. The pair of L-shaped plates 19 are fixedly connected to the inner wall of the first shell 3. A support rod 20 is arranged on the inner side of the pair of L-shaped plates 19. One end of the support rod 20 is fixedly connected to the inner side of the L-shaped plate 19, and the end of the support rod 20 away from the L-shaped plate 19 is fixedly connected to the inner wall of the first shell 3. The outer side of the support rod 20 is slidably connected to a limiting plate 21. The end of the limiting plate 21 away from the L-shaped plate 19 is fixedly connected to a clamping plate 22. The end of the clamping plate 22 close to the limiting ring 10 is designed as a slope, and the end of the clamping plate 22 away from the limiting ring 10 passes through the first shell 3. A tension spring 23 is fixedly connected between the limiting plate 21 and the L-shaped plate 19, and the tension spring 23 is arranged on the outer side of the support rod 20.

When the limiting ring 10 drives the connecting device 9 to move toward the card plate 22, the limiting ring 10 will contact and squeeze the inclined surface of the card plate 22. The inclined surface of the card plate 22 will move due to the force. The card plate 22 moves and then pulls the tension spring 23 through the limiting plate 21. The tension spring 23 is deformed and accumulates force. When the limiting ring 10 brings the connecting device 9 into contact with the charging base inside the installation groove 2, the limiting ring 10 is still in the state of squeezing the card plate 22, and the end of the card plate 22 away from the limiting ring 10 is stuck in the installation groove 2 The first shell 3 is quickly fixed inside, so that the camera body 5 is quickly fixed through the second shell 4. When the limiting ring 10 drives the electrical connector 9 to move away from the card plate 22, the limiting ring 10 will stop squeezing the card plate 22. The tension spring 23 is no longer stressed at this time, and the potential energy is released instantly, and the card plate 22 is driven to reset through the limiting plate 21. At this time, the card plate 22 will stop being engaged with the inside of the installation groove 2 at the end away from the limiting ring 10, thereby realizing the function of quickly disassembling the camera body 5.

As shown in Figures 6 and 7, the heat dissipation mechanism also includes a motor 24, and the motor 24 is electrically connected to the camera transmitter 7. The motor 24 is fixedly connected to the end of the fixing plate 15 away from the electrical connector 9. The output end of the motor 24 is sleeved with a first sprocket 25, and the outer side of the hollow rod 8 is rotatably connected to a second sprocket, and the end of the second sprocket away from the limiting ring 10 is fixedly connected to a fan blade 26, and a chain 27 is wound around the outer sides of the first sprocket 25 and the second sprocket.

When the camera transmitter 7 is powered on, it means that the camera body 5 has been installed. At this time, the camera transmitter 7 transmits power to the motor 24. The operation of the motor 24 will drive the first sprocket 25 to rotate. The rotation of the first sprocket 25 will drive the second sprocket to rotate through the chain 27. The rotation of the second sprocket will drive the fan blades 26 to rotate. The rotation of the fan blades 26 will blow wind toward the camera body 5, driving the air circulation inside the camera body 5, thereby realizing the heat dissipation function.

As shown in Figures 8 to 10, the sealing mechanism also includes five groups of limiting grooves 28, which are arranged in a uniform circumferential array inside the connecting circular plate 18. The insides of the five groups of limiting grooves 28 are all slidably connected with guide rods 29, and the end of the guide rod 29 close to the connecting circular plate 18 is fixedly connected with a nut 30, the diameter of the nut 30 is greater than the width of the limiting groove 28, and the nut 30 is arranged at the end of the connecting circular plate 18 away from the second meshing ring 17. The inside of the connecting circular plate 18 is rotatably connected with a fixed disk 32, and the outer side of the fixed disk 32 is fixedly connected with a pair of fixing rods 31, and the pair of fixing rods 31 both penetrate the second meshing ring 17 and are slidably connected to the inside of the second meshing ring 17, and the ends of the pair of fixing rods 31 away from the fixing disk 32 are fixed to the inside of the first shell 3, and the outer side of the guide rod 29 is penetrated with a baffle 33, and the inside of the baffle 33 is penetrated with a hinged rod 34, and the hinged rod 34 is fixed to the end of the fixing disk 32 close to the connecting circular plate 18.

When the second meshing ring 17 rotates clockwise from the perspective of Figure 9, it will drive the connecting circular plate 18 to rotate synchronously. During the rotation of the connecting circular plate 18, the limit groove 28 opened inside it will squeeze the guide rod 29, forcing the guide rod 29 to move. Since the guide rod 29 passes through the baffle 33, and the other end of the baffle 33 is rotatably connected to one end of the fixed plate 32 through the hinge rod 34, when the guide rod 29 moves, the guide rod 29 will drive the baffle 33 to rotate, thereby opening the inside of the connecting circular plate 18. The setting of the fixed rod 31 can support the fixed plate 32 to ensure that the normal rotation of the second meshing ring 17 is not hindered when the fixed plate 32 remains stationary. It should be noted that when the second meshing ring 17 rotates to a specified number of circles, the fixed rod 31 will not affect the rotation of the second meshing ring 17.

As shown in Figures 7 and 11, a cleaning mechanism is provided inside the camera body 5, and the cleaning mechanism is used to clean the outside of the camera body 5. The cleaning mechanism includes a scraper bar 38, and the scraper bar 38 is in contact with the outside of the camera body 5. The cleaning mechanism also includes a driving component and a reset component. The driving component is used to drive the scraper bar 38 to rotate, and the reset component is used to drive the scraper bar 38 to reset after rotation.

On rainy days, water droplets are easily attached to the outside of the camera body 5, which causes the user to observe the outside world through the camera body 5 from inside the vehicle and the display is relatively blurry. In order to solve the above problem, when the embodiment of the present invention is in use, the motor 24 will drive the driving component to operate during rotation, and the operation of the driving component will drive the scraper 38 to rotate along the outside of the camera body 5, and the rotation of the scraper 38 will also drive the reset component to operate. When the driving component drives the scraper 38 to move to the extreme distance outside the camera body 5, the power source of the driving component for the scraper 38 disappears instantly, and the reset component will instantly drive the scraper 38 to reset. After the scraper 38 is reset, the driving component will operate again, thereby repeating the above-mentioned effect. Through the structural design of the driving component and the reset component, the two can cooperate to reciprocate and drive the scraper 38 to operate, thereby cleaning the water droplets and impurities on the outside of the camera body 5, solving the problem of blurred vision caused by water droplets and impurities attached to the outside of the camera body 5.

As shown in Figures 7 and 11, the driving assembly includes a first bevel gear 35, which is fixedly connected to the output end of the motor 24. A groove is provided on the outer side of the first bevel gear 35. A second bevel gear 36 is meshed with one side of the first bevel gear 35. A first connecting rod 37 is fixedly connected to the inside of the second bevel gear 36. The first connecting rod 37 passes through the camera body 5 and is fixedly connected to the inner side of the scraper strip 38. A second connecting rod 39 is fixedly connected to the inner side of the scraper strip 38. The second connecting rod 39 passes through the camera body 5, and the first connecting rod 37 and the second connecting rod 39 are symmetrically distributed.

When the motor 24 is running, it drives the first sprocket 25 to rotate, and the rotation of the first sprocket 25 will drive the first connecting rod 37 to rotate. When the first connecting rod 37 rotates, it will drive the scraper bar 38 to rotate. When the scraper bar 38 rotates, it will drive the reset component to operate through the second connecting rod 39. The reset component is deformed and accumulates momentum. When the groove opened on the outer side of the first bevel gear 35 rotates to the position of the second bevel gear 36, the first bevel gear 35 and the second bevel gear 36 are affected by the groove and are in a non-engaged state for a short time. The scraper bar 38 ends the force applied to the reset component through the second connecting rod 39, and the reset component instantly drives the scraper bar 38 to reset through the second connecting rod 39. It should be noted that the speed at which the reset component drives the scraper bar 38 to reset through the second connecting rod 39 is greater than the rotation speed of the first bevel gear 35. Subsequently, the first bevel gear 35 rotates and meshes with the second bevel gear 36 again, thereby repeating the above action again, so that the scraper bar 38 continuously scrapes the wall outside the camera body 5 to clean it.

As shown in Figures 7 and 11, the reset assembly includes a reset disk 40, which is fixedly connected to the inner wall of the camera body 5, and the second connecting rod 39 passes through the reset disk 40. A coil spring 41 is fixedly connected to one end of the reset disk 40 close to the second bevel gear 36, and a fixed block 42 is fixedly connected to the other end of the coil spring 41. The fixed block 42 is fixedly connected to one end of the reset disk 40 close to the second bevel gear 36.

When the scraper strip 38 drives the second connecting rod 39 to rotate, the second connecting rod 39 will drive one end of the coil spring 41 to rotate synchronously, and the rotation of one end of the coil spring 41 will cause deformation to generate elastic potential energy. When the second connecting rod 39 ends pulling the coil spring 41, the pulling force generated by the second connecting rod 39 on the coil spring 41 also ends. The coil spring 41 instantly releases the elastic potential energy and drives the scraper strip 38 to reset through the second connecting rod 39.

A method for assembling a vehicle-mounted camera with high heat dissipation performance, the method comprising the following steps;

S1. First, insert the first housing 3 into the mounting groove 2 provided inside the fender 1, and then rotate the steering ring 14. The steering ring 14 rotates to drive the guide ring 12 to rotate through the limit rod 13, and the guide ring 12 is meshed with the screw 11. Since the steering ring 14 is fixed in position, it can only rotate but cannot move;

S2. Therefore, during the rotation of the guide ring 12, the screw rod 11 will be driven to move toward the electrical connector 9. At this time, the screw rod 11 drives the electrical connector 9 to move along the outer side of the hollow rod 8 through the limit ring 10. As the limit ring 10 continues to move, the limit ring 10 will contact and squeeze the disassembly mechanism;

S3. When the limiting ring 10 drives the electrical connector 9 to contact the charging base inside the mounting groove 2, the charging base can transmit electricity to the camera transmitter 7 through the electrical connector 9, and the disassembly mechanism also limits the first shell 3, so that the first shell 3 cannot move, thereby realizing the function of quickly fixing the camera body 5;

S4. When the user starts the power supply and checks the situation outside the vehicle through the camera body 5, the camera transmitter 7 not only serves as a data transfer transmission end, but also can be used as a battery to provide a power source for the heat dissipation mechanism when the power is turned on;

S5, starting the heat dissipation mechanism to blow air to the camera body 5 when it is started, thereby improving the air circulation inside the camera body 5, thereby achieving the function of heat dissipation.

Working principle: The first housing 3 is installed on the outer fender 1 of the vehicle by bolt connection. When the vehicle needs to use the vehicle-mounted camera, the control end in the vehicle collects external information through the camera body 5, and the obtained data is then transmitted to the vehicle control end through the camera transmitter 7. However, the vehicle-mounted camera will generate a lot of heat when working. If the heat cannot be effectively dissipated, it will affect the performance and life of the camera body 5. In addition, the existing vehicle-mounted camera assembly structure is usually assembled using fasteners such as screws. This method not only has low assembly efficiency, but also the fasteners are easy to loosen or fall off, affecting the stability and service life of the camera body 5. In order to solve the above problems, when the embodiment of the present invention is used, the first housing 3 is first inserted into the installation groove 2 opened inside the fender 1, and then the steering ring 14 is rotated. The rotation of the steering ring 14 drives the guide ring 12 to rotate through the limit rod 13, and the guide ring 12 is meshed with the screw 11. Since the position of the steering ring 14 is fixed, it can only rotate but not move. Therefore, during the rotation of the guide ring 12, it will drive the screw 11 to move toward the electrical connector 9. At this time, the screw 11 moves along The outer side of the hollow rod 8 drives the electrical connector 9 to move through the limiting ring 10. As the limiting ring 10 moves continuously, the limiting ring 10 will contact and squeeze the disassembly and assembly mechanism. When the limiting ring 10 drives the electrical connector 9 to contact the charging base inside the mounting groove 2, the charging base can transmit electricity to the camera transmitter 7 through the electrical connector 9 (the camera transmitter 7 is a prior art with mature technology and is used for data transfer transmission in video recording. It will not be introduced in detail in the article). The disassembly and assembly mechanism also limits the first shell 3, so that the first shell 3 cannot move, thereby realizing the function of quickly fixing the camera body 5. Through the above-mentioned structural design, the camera body 5 can be powered on without performing additional operations during the process of quickly fixing the camera body 5, which improves the convenience of device installation and shortens the working time. When the user starts the power supply and checks the situation outside the vehicle through the camera body 5, the camera transmitter 7 is not only used as a data transfer transmission end, but also can be used for a battery. When the power is turned on, the heat dissipation mechanism can be powered on to provide a power source, so that the heat dissipation mechanism is started, and the camera body 5 is blown when it is started, thereby improving the camera. The air inside the camera body 5 circulates, thereby achieving the function of heat dissipation, and the inner and outer bodies of the camera body 5 are made of heat-conducting materials, and the heat-conducting materials are heat-conducting silicone sheets. Before the vehicle-mounted camera is transported or installed, the electronic components inside it are easily damp, causing damage to the electronic components and affecting the service life of the device. Before use, the interior of the present invention is affected by the sealing mechanism and is in a relatively sealed state, which can effectively solve the above problems. When the steering ring 14 is rotated, the first meshing ring 16 will be driven to rotate through the limiting rod 13, and the rotation of the first meshing ring 16 will drive the second meshing ring 17 to rotate synchronously. The rotation of the second meshing ring 17 will then cooperate with the connecting circular plate 18 to operate its sealing mechanism. The operation of the sealing mechanism will open the center of the connecting circular plate 18, thereby avoiding the situation that the limiting ring 10 drives the electrical connector 9 to move toward the fender 1 and is unable to move due to the sealing mechanism. Through this structural design, it can be achieved that before the camera body 5 is installed, a certain degree of sealing inside it is guaranteed, effectively preventing moisture inside it, or dust and impurities from the outside from adhering to the electronic components inside the camera body 5, and when installing the camera When the head body 5 is removed, the sealing mechanism will operate and will not hinder the normal movement of the electrical connector 9, thereby improving the linkage of the device. It should be noted that the structure installed inside the first shell 3, the second shell 4 and the camera body 5 will not hinder the installation of the normal required parts of the vehicle-mounted camera. The vehicle-mounted camera is a prior art and the technology is mature. It will not be introduced in detail in the article. When disassembling the camera body 5, it is only necessary to rotate the steering ring 14 in the opposite direction. The reverse rotation of the steering ring 14 will eventually drive the electrical connector 9 to reset. The reset of the electrical connector 9 will disconnect the camera transmitter. 7 is powered on, the camera body 5 does not need to work at this time, and the camera transmitter 7 ends the power supply to the heat dissipation mechanism, and the heat dissipation mechanism stops running. During the resetting process of the electrical connector 9, the sealing mechanism is also in a reset state. When the electrical connector 9 is completely reset, the sealing mechanism is also completely reset, and the interior of the camera body 5 is sealed again, thereby playing a moisture-proof and dust-proof function. When the limit ring 10 drives the electrical connector 9 to move toward the card plate 22, the limit ring 10 will contact and squeeze the inclined surface of the card plate 22, and the inclined surface of the card plate 22 will move when the force is applied, and the card plate 22 moves. Then, the tension spring 23 is pulled by the limit plate 21, and the tension spring 23 is deformed and accumulates force. When the limit ring 10 is brought to the charging base inside the electrical connector 9 and the mounting groove 2, the limit ring 10 is still in a state of squeezing the card plate 22, and the end of the card plate 22 away from the limit ring 10 will be engaged in the inside of the mounting groove 2, and the first shell 3 is quickly fixed, so that the camera body 5 is quickly fixed through the second shell 4. When the limit ring 10 drives the electrical connector 9 to move in the direction away from the card plate 22, the limit ring 10 will end the card plate The end of the card plate 22 away from the limiting ring 10 will stop engaging with the inside of the installation slot 2, thereby realizing the function of quickly disassembling the camera body 5. When the camera transmitter 7 is powered on, it means that the camera body 5 has been installed. At this time, the camera transmitter 7 transmits power to the motor 24. The operation of the motor 24 will drive the first sprocket 25 to rotate, and the rotation of the first sprocket 25 will drive the second sprocket to rotate through the chain 27. The rotation of the second sprocket drives the fan blades 26 to rotate. The rotation of the fan blades 26 will blow the wind toward the camera body 5, driving the air circulation inside the camera body 5, thereby realizing the heat dissipation function. When the second engagement ring 17 rotates clockwise from the perspective of FIG. 9, it will drive the connecting circular plate 18 to rotate synchronously. During the rotation of the connecting circular plate 18, the limiting groove 28 provided inside it will squeeze the guide rod 29, forcing the guide rod 29 to move. Since the guide rod 29 passes through the baffle 33, and the other end of the baffle 33 is rotatably connected to one end of the fixed plate 32 through the hinge rod 34, Therefore, when the guide rod 29 moves, the guide rod 29 will drive the baffle plate 33 to rotate, thereby opening the inside of the connecting circular plate 18, and the setting of the fixing rod 31 can support the fixing plate 32 to ensure that the fixing plate 32 remains stationary without hindering the normal rotation of the second meshing ring 17. It should be noted that when the second meshing ring 17 rotates to a specified number of circles, the fixing rod 31 will not affect the rotation of the second meshing ring 17. On rainy days, water droplets are easily attached to the outside of the camera body 5, which may cause the user to pass through the camera from the inside of the vehicle. When the camera body 5 observes the external situation, the display is relatively blurred. In order to solve the above problem, when the embodiment of the present invention is in use, the motor 24 will drive the driving component to operate during the rotation process, and the operation of the driving component will drive the scraper 38 to rotate along the outer side of the camera body 5, and the rotation of the scraper 38 will also drive the reset component to operate. When the driving component drives the scraper 38 to move to the limit distance outside the camera body 5, the power source of the driving component for the scraper 38 disappears instantly, and the reset component will instantly drive the scraper 38 to reset. After the scraper 38 is reset, the driving component will operate again, thereby repeating the above action. Through the structural design of the driving component and the reset component, the two can cooperate to reciprocate and drive the scraper 38 to operate, thereby cleaning the water droplets and impurities on the outside of the camera body 5, solving the problem of blurred vision caused by water droplets and impurities attached to the outside of the camera body 5. When the motor 24 is running, it drives the first sprocket 25 to rotate, and the rotation of the first sprocket 25 will drive the first connecting rod 37 to rotate. When the first connecting rod 37 rotates, it will drive the scraper 38 to rotate. When the scraper 38 rotates, it will drive the reset through the second connecting rod 39. When the reset assembly is running, the reset assembly is deformed and accumulates momentum, and when the groove opened on the outer side of the first bevel gear 35 rotates to the position of the second bevel gear 36, the first bevel gear 35 and the second bevel gear 36 are affected by the groove and are in a non-engaged state for a short time, and the scraper strip 38 ends its force on the reset assembly through the second connecting rod 39, and the reset assembly instantly drives the scraper strip 38 to reset through the second connecting rod 39. It should be noted that the speed at which the reset assembly drives the scraper strip 38 to reset through the second connecting rod 39 is greater than the rotation speed of the first bevel gear 35. Subsequently, the first bevel gear 35 The second connecting rod 39 rotates and meshes with the second bevel gear 36 again, thereby repeating the above-mentioned action, so that the scraper strip 38 continuously scrapes the wall outside the camera body 5 to clean it. When the scraper strip 38 drives the second connecting rod 39 to rotate, the second connecting rod 39 will drive one end of the coil spring 41 to rotate synchronously, and the rotation of one end of the coil spring 41 will cause deformation to generate elastic potential energy. When the second connecting rod 39 ends pulling the coil spring 41, the pulling force generated by the second connecting rod 39 on the coil spring 41 ends, and the coil spring 41 instantly releases the elastic potential energy and drives the scraper strip 38 to reset through the second connecting rod 39.

The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
