[0001] The present invention relates to the technical field of 3D cameras, and in particular to a 3D camera with a heat dissipation structure. Background Art

[0002] A 3D camera is a device that can obtain the geometric shape and texture information of the surface of an object in three-dimensional space. It captures the three-dimensional information of an object through different technologies and sensors, and is usually used in industrial measurement, computer vision, virtual reality, augmented reality, medical imaging and other fields.

[0003] Chinese patent publication number CN218240653U discloses "a 3D camera", including a housing, a projection host, two telescopic arms and two cameras. The housing forms a receiving cavity with an opening, the projection host is arranged in the receiving cavity, the light beam emitted by the projection host passes through the opening, two telescopic arm mechanisms and two cameras, the two telescopic arm mechanisms extend along a preset direction, and are respectively connected to two opposite sides of the housing, the two cameras are respectively connected to the end of the corresponding telescopic arm mechanism away from the housing, the shooting direction of the camera is adjustable, and the length of the telescopic arm mechanism along the preset direction is adjustable. This patent can flexibly adjust the distance and angle between the two cameras to be suitable for shooting objects at close and long distances respectively, with strong versatility and a simple and uncomplicated structure.

[0004] During the conception process, the applicant searched a large number of patent documents on the patent network. For example, Chinese patent publication number CN218240653U discloses that "a 3D camera" is used in an environment with a relatively high ambient temperature. Due to the high temperature of the surrounding environment, when the temperature of the air itself rises, the heat dissipation capacity of the air will be weakened, so that the effect of heat dissipation through air conduction and convection is weakened. The heat generated inside the camera may accumulate faster, causing the temperature to continue to rise. If the heat dissipation is not enough to offset the heat generation, the camera may overheat, thereby affecting its stability and lifespan. Therefore, a 3D camera with a heat dissipation structure is proposed to solve the above-mentioned problems. Summary of the invention

[0026] 2. The D camera with a heat dissipation structure, through the provision of a dustproof component, enables the filter to intercept larger debris in the air, such as small insects, catkins, etc., and the filter element can intercept fine dust in the air, thereby preventing dust and fine debris from entering the casing through the air inlet, causing a certain impact on the accessories in the casing, and causing a certain impact on the heat dissipation effect; through the provision of a cleaning brush, the cleaning brush can continuously clean the surface of the filter element through movement, thereby preventing the filter element from being attached to a large amount of dust on its surface after long-term use, resulting in reduced gas permeability, thereby affecting ventilation and heat dissipation effects; through the provision of multiple cone heads, the multiple cone heads can clear and clean multiple circular holes on the filter net, thereby preventing the circular holes from being blocked after long-term use, thereby affecting the use effect.

The sliding frame 84 drives a plurality of flipping sheets 85 to move synchronously. The plurality of flipping sheets 85 shovel the desiccant at the bottom of the drying box 86 and flip it up.

[0052] By setting the drying component 8, the desiccant in the drying box 86 can absorb the moisture inside the housing 1, so as to avoid the humid air entering the housing 1 when used in a humid environment, causing the main board 3 and the lens assembly 2 to be damp, thereby increasing the failure rate and thus affecting their service life; by setting the flip sheet 85, the flip sheet 85 can continuously shovel and flip the desiccant at the bottom layer in the drying box 86, so as to avoid the desiccant from caking after long-term use, thereby reducing the drying effect.

[0053] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0054] Working principle: start the motor 61, the motor 61 drives the shaft 62 to rotate, the shaft 62 drives the fan 63 to rotate, and when the fan 63 rotates, the air inside the casing 1 is discharged from the casing 1 through the air outlet 4. After the air inside the casing 1 is discharged, due to the negative pressure, the casing 1 absorbs the external air to the inside of the casing 1 through the air inlet 5, so that the air inside the casing 1 circulates continuously, and the heat inside the casing 1 is absorbed and brought out of the casing 1 through the air; the buffer box 64, the guide tube 65, the heat dissipation water pipe 67, the cooling water pipe 68, the cooling box 69, and the return pipe 610 are all filled with coolant. When the shaft 62 rotates, the shaft 62 drives the impeller 66 to rotate. When the impeller 66 rotates, the coolant inside the buffer box 64 is passed The guide tube 65 transports the coolant to the heat dissipation water pipe 67. The coolant in the heat dissipation water pipe 67 is transported to the inside of the cooling box 69 through the cooling water pipe 68. The coolant in the cooling box 69 flows back to the buffer box 64 through the return pipe 610. When the coolant flows to the heat dissipation water pipe 67, the fan 63 cools the heat dissipation water pipe 67 and the coolant inside by air cooling. When the cooled coolant flows to the cooling water pipe 68, the air inhaled by the air inlet 5 contacts the cooling water pipe 68, so that the cooling water pipe 68 cools the air by contacting the air. When the coolant flows to the cooling box 69, the cooling box 69 absorbs the heat generated by the mainboard 3 by cooperating with the silicone grease to achieve the effect of heat exchange. When it flows to the buffer box 64, the buffer box 64 absorbs the heat on the rear side of the lens assembly 2 through the cooperation of the silicone grease and the lens assembly 2, thereby achieving the effect of heat exchange. At this time, the temperature of the coolant in the buffer box 64 rises, and the coolant is cooled again through the cooperation of the heat dissipation water pipe 67 and the fan 63 and then circulates. Through the setting of the heat dissipation assembly 6, the fan 63 can continuously discharge the hot air inside the casing 1 through the air outlet 4 out of the casing 1, and the casing 1 then draws the external air into the casing 1 through the air inlet 5, and absorbs and takes away the heat inside the casing 1 through the circulating flow of air, thereby achieving the effect of heat dissipation, and at the same time avoids the problem that the conventional radiator, due to the air inlet and outlet sharing the same outlet, causes the air to gather at the radiator and flow, and in the casing 1 The internal air circulation is poor, resulting in poor heat dissipation effect; through the cooperation of the buffer box 64, the guide tube 65, the heat dissipation water pipe 67, the cooling water pipe 68, the cooling box 69, and the return pipe 610, the coolant circulates to absorb the heat accumulated at the air inlet 5, the main board 3, and the lens assembly 2, and then exchanges heat with the air through the fan 63 to discharge the heat from the casing 1, thereby achieving the effect of cooling the main board 3 and the lens assembly 2, extending the service life of the main board 3 and the lens assembly 2, and further promoting the cooling effect by lowering the temperature of the incoming air, which can avoid the poor heat exchange effect of the air due to the high temperature of the surrounding air when used in a high temperature environment, thereby failing to achieve the cooling effect.

[0055] The filter screen 72 can intercept larger debris in the air, and the filter element 71 can intercept fine dust in the air, thereby preventing dust from entering the interior of the housing 1. When the rotating shaft 62 rotates, the rotating shaft 62 drives the wheel shaft 73 to rotate through the belt 74, and the wheel shaft 73 drives the No. 1 sliding shaft 75 to rotate. Through the cooperation of the No. 1 sliding shaft 75, the double-hole sliding ring 77, and the No. 2 sliding shaft 76, the No. 1 sliding shaft 75 can drive the driven shaft 78 to rotate through the No. 2 sliding shaft 76. When the driven shaft 78 rotates, the reciprocating thread and the ball bearing on its surface drive the slider 79 to reciprocate. When the slider 79 reciprocates, it drives the cleaning brush 710 to reciprocate. The cleaning brush 710 cleans the dust on the surface of the filter element 71 through the reciprocating movement; when the cleaning brush 710 moves, the cleaning brush 710 drives the mounting plate 712 to move synchronously through the multiple spring pieces 711, and the mounting plate 712 drives the multiple cone heads 713 to move synchronously when the mounting plate 712 moves. Due to the elastic force of the multiple spring pieces 711, During the movement, the multiple cone heads 713 will continuously slide into the holes on the filter screen 72 and then slide out, thereby achieving the effect of cleaning the holes; through the setting of the dustproof component 7, the filter screen 72 can intercept larger debris in the air, such as small insects, catkins, etc., and the filter element 71 can intercept fine dust in the air, thereby preventing dust and fine debris from entering the casing 1 through the air inlet 5, causing a certain impact on the accessories in the casing 1, and causing a certain impact on the heat dissipation effect; through the setting of the cleaning brush 710, the cleaning brush 710 can continuously clean the surface of the filter element 71 through movement, thereby preventing the filter element 71 from having a lot of dust attached to its surface after long-term use, resulting in reduced gas permeability, thereby affecting ventilation and heat dissipation effects; through the setting of the multiple cone heads 713, the multiple cone heads 713 can clear and clean the multiple circular holes on the filter screen 72, thereby preventing the circular holes from being blocked after long-term use, thereby affecting the use effect.

[0056] The drying box 86 is filled with desiccant. When the driven shaft 78 rotates, the driven shaft 78 drives the annular slide 81 to rotate. The annular slide 81 drives the hinge block 82 to reciprocate through the ball bearing. The hinge block 82 drives the sliding frame 84 to reciprocate through the connecting rod 83. The sliding frame 84 drives the multiple flipping plates 85 to move synchronously. The multiple flipping plates 85 shovel the desiccant at the bottom of the drying box 86 and flip it up. Through the setting of the drying assembly 8, the desiccant in the drying box 86 can absorb the moisture inside the housing 1 to avoid the desiccant in a humid environment. When the desiccant is used in the lower part, humid air enters the housing 1, causing the mainboard 3 and the lens assembly 2 to be damp, increasing the failure rate and thus affecting their service life. By setting the flip sheet 85, the flip sheet 85 can continuously shovel and flip the desiccant at the bottom layer in the drying box 86, thereby preventing the desiccant from caking after long-term use, thereby reducing the drying effect. After being flipped, the desiccant can increase the contact area with the air, further improving the drying effect, and facilitating the recovery of the desiccant, thereby extending the service life of the desiccant.
