[0027] With the increasing prevalence of remote interaction scenarios, display devices with integrated cameras are being used more and more widely in daily work and life. To meet the shooting needs of different application scenarios, some display devices are equipped with adjustable camera components, allowing users to change the shooting angle or height of the camera according to actual usage needs.

[0028] Currently, camera component adjustments generally rely on manual operation by the user; this method requires the user to directly touch the camera, which is inconvenient. Furthermore, during continuous operation, display devices with integrated cameras generate a significant amount of heat from their internal heat-generating components. If this heat is not dissipated in time, it can easily accumulate inside the display device, leading to localized temperature increases and negatively impacting the operational stability of the corresponding electronic components and the display's overall performance.

[0029] To address the aforementioned issues, this application proposes a camera assembly designed to achieve lifting and rotation adjustment of the camera on a display device by driving it with airflow, thereby improving the ease of adjustment and simultaneously using airflow to dissipate heat from the display device, thus enhancing its operational stability.

[0030] Please see Figure 1 , Figure 3 and Figure 4 and for reference Figure 6 and Figure 7An embodiment of this application provides a camera assembly 1000, comprising: a base 1, which has a first receiving cavity 101, a first air supply channel 102, a second air supply channel 103, and an exhaust channel 104; the exhaust channel 104 is used to connect to the heat dissipation area 2100 of the display body 2000; and a movable seat 2, which is slidably fitted into the first receiving cavity 101; the movable seat 2 divides the first receiving cavity 101 into a first sub-cavity 1011 and a second sub-cavity 1012, the first sub-cavity 1011 being connected to the first air supply channel 102 and the exhaust channel 104, and the second sub-cavity 1012 being connected to the second air supply channel 103 and the exhaust channel 104. Air passage 103 and exhaust passage 104 are connected; camera body 3 is rotatably connected to movable seat 2; turbine 4 is connected to camera body 3; turbine 4 is connected to second sub-chamber 1012; when external gas is supplied into first sub-chamber 1011 through first air supply passage 102, the volume of first sub-chamber 1011 increases and causes movable seat 2 to descend; when external gas is supplied into second sub-chamber 1012 through second air supply passage 103, the volume of second sub-chamber 1012 increases and causes movable seat 2 to rise, and turbine 4 causes camera body 3 to rotate under the action of airflow in second sub-chamber 1012.

[0031] In this embodiment, the base 1 serves as the fixed foundation component for the camera assembly 1000, and a first receiving cavity 101 is formed inside it. The base 1 also contains a first air supply channel 102, a second air supply channel 103, and an exhaust channel 104. The first air supply channel 102, the second air supply channel 103, and the exhaust channel 104 are respectively pathway structures disposed inside the base 1, used to allow gas to flow along a specific path. One end of the first air supply channel 102 is connected to an external air source, and the other end is connected to the first receiving cavity 101, used to introduce external gas into the first receiving cavity 101; one end of the second air supply channel 103 is connected to an external air source, and the other end is connected to the first receiving cavity 101, used to introduce external gas into the first receiving cavity 101. The external air source can be an independently installed air pump or an existing air supply device inside the display device. One end of the exhaust channel 104 is connected to the first receiving cavity 101, and the other end is used to connect to the heat dissipation area 2100 of the display body 2000. Gas in the first receiving cavity 101 can be discharged through the exhaust channel 104 to the heat dissipation area 2100 of the display body 2000 to achieve heat dissipation of the display body 2000. The heat dissipation area 2100 refers to the parts of the display body 2000 that generate heat during operation and need to be dissipated, such as the back area of ​​the display panel, the area where the main control chip is located, the area where the lamp board component is located, or other areas with large heat generation.

[0032] The movable seat 2 is disposed in the first receiving cavity 101 of the base 1 and is capable of vertical movement relative to the base 1 along the depth direction of the first receiving cavity 101. The outer peripheral contour of the movable seat 2 is adapted to the inner peripheral wall of the first receiving cavity 101 to ensure that the movable seat 2 can slide smoothly in the first receiving cavity 101, while maintaining a sealed fit between the outer wall of the movable seat 2 and the inner peripheral wall of the first receiving cavity 101 to prevent gas leakage between the movable seat 2 and the inner peripheral wall of the first receiving cavity 101. This sealed fit can be achieved by setting a sealing ring on the outer peripheral wall of the movable seat 2, or by using a clearance fit between the movable seat 2 and the inner peripheral wall of the first receiving cavity 101 and filling it with a sealing medium. The movable seat 2 divides the first receiving cavity 101 along its depth direction into two independent spaces, namely the first sub-cavity 1011 and the second sub-cavity 1012. The first sub-chamber 1011 is located above the movable seat 2 and is formed by the top surface of the movable seat 2, the top wall of the first receiving cavity 101, and the side wall of the first receiving cavity 101. The second sub-chamber 1012 is located below the movable seat 2 and is formed by the bottom surface of the movable seat 2, the bottom wall of the first receiving cavity 101, and the side wall of the first receiving cavity 101. The first sub-chamber 1011 is connected to the first air supply channel 102. When external gas enters the first sub-chamber 1011 through the first air supply channel 102, the amount of gas in the first sub-chamber 1011 increases and the air pressure rises. The second sub-chamber 1012 is connected to the second air supply channel 103. When external gas enters the second sub-chamber 1012 through the second air supply channel 103, the amount of gas in the second sub-chamber 1012 increases and the air pressure rises. Meanwhile, both the first sub-chamber 1011 and the second sub-chamber 1012 are connected to the exhaust channel 104, and the gas in the first sub-chamber 1011 and the gas in the second sub-chamber 1012 can be discharged to the heat dissipation area 2100 of the display body 2000 through the exhaust channel 104.

[0033] The camera body 3 is mounted on the movable base 2 and is rotatably connected to the movable base 2. The camera body 3 is used to acquire images and contains components found in conventional cameras, such as an image sensor and an optical lens. The camera body 3 can rotate relative to the movable base 2 about a rotation axis, which is usually extended vertically, so that the camera body 3 can be angled in the horizontal plane, thereby changing the shooting direction of the camera body 3.

[0034] The turbine 4 is located inside the base 1 or the movable seat 2 and is connected to the camera body 3. This connection can be direct, such as a coupling connecting the output shaft of the turbine 4 to the rotating shaft of the camera body 3, or indirect, such as a transmission connection between the turbine 4 and the camera body 3 via a gear transmission mechanism, worm gear transmission mechanism, or belt transmission mechanism. The turbine 4 is a device that converts the kinetic energy of flowing gas into rotational mechanical energy. It has a blade structure inside. When the airflow passes through the blades of the turbine 4, the airflow exerts a thrust on the blades, causing them to rotate around the rotation axis of the turbine 4, thereby driving the camera body 3 connected to the turbine 4 to rotate synchronously. The turbine 4 is connected to the second sub-chamber 1012, meaning that the gas in the second sub-chamber 1012 can flow through the turbine 4. Specifically, the second sub-chamber 1012 can be directly connected to the air inlet of the turbine 4, or the second sub-chamber 1012 can be connected to the air inlet of the turbine 4 through an air passage located inside the base 1 or the movable seat 2. When the gas in the second sub-chamber 1012 is discharged, the gas flows through the turbine 4, thereby driving the turbine 4 to rotate.

[0035] When the camera assembly 1000 is in operation, it has two different operating states depending on the gas supply method: When external gas is supplied into the first sub-chamber 1011 through the first gas supply channel 102, the amount of gas in the first sub-chamber 1011 continuously increases; since the first sub-chamber 1011 is a sealed space, the air pressure in the first sub-chamber 1011 increases with the increase in gas volume. When the air pressure in the first sub-chamber 1011 is higher than the air pressure in the second sub-chamber 1012 and the external ambient air pressure, this air pressure exerts a downward force on the top surface of the movable seat 2, pushing the movable seat 2 to slide towards the bottom wall of the first receiving cavity 101, that is, the movable seat 2 descends relative to the base 1. At the same time, the volume of the first sub-chamber 1011 increases as the movable seat 2 descends to accommodate the continuously supplied gas. The descent of the movable seat 2 causes the camera body 3 mounted on the movable seat 2 to descend accordingly, thereby realizing the position adjustment of the camera body 3 in the height direction. During this process, the descent of the movable seat 2 will compress the volume of the second sub-chamber 1012. As the volume decreases and the pressure increases, the gas inside the second sub-chamber 1012 is forced through the exhaust channel 104 into the heat dissipation area 2100 of the display body 2000 to dissipate heat. When the movable seat 2 descends to the target position, it stops moving, and the volumes of the first sub-chamber 1011 and the second sub-chamber 1012 no longer change. At this time, the air pressure in the first sub-chamber 1011 continuously increases due to the continuous supply of external gas, and the gas inside the first sub-chamber 1011 can be discharged through the exhaust channel 104 into the heat dissipation area 2100 of the display body 2000 for continuous heat dissipation.

[0036] When external gas is supplied into the second sub-chamber 1012 through the second gas supply channel 103, the amount of gas in the second sub-chamber 1012 continuously increases, and the air pressure rises accordingly. When the air pressure in the second sub-chamber 1012 is higher than the air pressure in the first sub-chamber 1011 and the external ambient air pressure, this air pressure exerts an upward force on the bottom surface of the movable seat 2, pushing the movable seat 2 to slide towards the top wall of the first receiving cavity 101, that is, the movable seat 2 rises relative to the base 1. During the rising process of the movable seat 2, the volume of the second sub-chamber 1012 continuously increases to accommodate the continuously supplied gas; the rising of the movable seat 2 causes the camera body 3 mounted on the movable seat 2 to rise accordingly, thereby realizing the position adjustment of the camera body 3 in the height direction; at the same time, the airflow supplied into the second sub-chamber 1012 drives the blades of the turbine 4 to rotate, and the turbine 4 in turn drives the camera body 3 connected to it to rotate around its rotation axis, thereby realizing the angle adjustment of the camera body 3. During this process, the rising of the movable seat 2 will compress the volume of the first sub-chamber 1011. As the volume decreases and the pressure increases, the gas inside the first sub-chamber 1011 will be forced through the exhaust channel 104 into the heat dissipation area 2100 of the display body 2000 to dissipate heat. When the movable seat 2 reaches the target position, it stops moving, and the volumes of the first sub-chamber 1011 and the second sub-chamber 1012 no longer change. At this time, the air pressure in the second sub-chamber 1012 continuously increases due to the continuous supply of external gas, and the gas inside the second sub-chamber 1012 can be discharged through the exhaust channel 104 into the heat dissipation area 2100 of the display body 2000 for continuous heat dissipation.

[0037] It should be noted that in both of the above-mentioned working states, the driving force of the turbine 4 on the camera body 3 is independent of the lifting and lowering movement of the movable seat 2. The rotation of the camera body 3 can occur at any time during its lifting and lowering process, specifically depending on when external gas is supplied through the second air supply channel 103 and when gas in the second sub-chamber 1012 flows through the turbine 4. There is no fixed temporal sequence or synchronous relationship between the lifting and lowering action and the rotation action of the camera body 3; they can overlap at least partially in time or occur separately at different times. Regarding the timing control of the above-mentioned lifting and lowering action and rotation action, appropriate valve structures or other airflow distribution components can be set to control the timing of airflow supply to the turbine 4, thereby ensuring the independence between the lifting and lowering action and the rotation action. This will not be elaborated further here.

[0038] In summary, during the rising and falling of the movable seat 2, the gas in the compressed sub-chamber can be discharged to the heat dissipation area 2100 through the exhaust channel 104. When the movable seat 2 has risen or fallen to its final position, the air pressure in the sub-chamber on the air intake side increases due to the continuous supply of external gas, and the gas inside can also be discharged to the heat dissipation area 2100 through the exhaust channel 104. At the same time, the lifting and lowering movement of the movable seat 2 causes the camera body 3 mounted on it to rise and fall accordingly, realizing the adjustment of the height of the camera body 3; the turbine 4 rotates under the action of the airflow discharged from the second sub-chamber 1012, thereby driving the camera body 3 to rotate, realizing the angle adjustment of the camera body 3.

[0039] Therefore, the camera assembly 1000 provided in this embodiment divides the first receiving cavity 101 in the base 1 into a first sub-cavity 1011 and a second sub-cavity 1012 by the movable seat 2, which controls the supply of external gas to different sub-cavities. This drives the movable seat 2 to rise and fall, thereby adjusting the position of the camera body 3 in the height direction. The turbine 4 is connected to the camera body 3 and communicates with the second sub-cavity 1012. When external gas is supplied to the second sub-cavity 1012 to drive the movable seat 2 to rise, the exhaust airflow flows through the turbine 4 and drives it to rotate, thereby automatically rotating the camera body 3 to adjust the shooting angle. One end of the exhaust channel 104 is connected to the first receiving cavity 101, and the other end is connected to the heat dissipation area 2100 of the display body 2000. During the raising and lowering of the movable seat 2 and after it has reached its position, the gas in each sub-cavity can be discharged to the heat dissipation area 2100 through the exhaust channel 104, thereby achieving forced convection cooling. At the same time, the exhaust channel 104 also provides a pressure relief path for the compressed sub-cavities, improving the smoothness of the raising and lowering movement. The camera assembly 1000 integrates lifting, angle adjustment, and auxiliary heat dissipation functions pneumatically, eliminating the need for manual operation by the user and thus improving ease of use. Compared to a solution that requires a separate drive motor for the camera assembly 1000, the structure is more compact, consumes less power, and generates less heat. Furthermore, it can utilize the existing air source in the display device for drive, resulting in a high degree of functional integration.

[0040] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7The movable seat 2 includes: a first seat body 201, which is slidably fitted into a first receiving cavity 101; the first seat body 201 divides the first receiving cavity 101 into a first sub-cavity 1011 and a second sub-cavity 1012; a second seat body 202, which is fixedly disposed within the first seat body 201; a second receiving cavity 203 is formed between the second seat body 202 and the first seat body 201; a turbine 4 is rotatably connected to the second seat body 202; and a third seat body 204, which is slidably fitted into the second receiving cavity 203; the third seat body 204 divides the first receiving cavity 1011 into a first sub-cavity 1011 and a second sub-cavity 1012. The second accommodating cavity 203 is divided into a third sub-cavity 2031 and a fourth sub-cavity 2032. The volume of the third sub-cavity 2031 increases as the third seat 204 descends, and the volume of the fourth sub-cavity 2032 increases as the third seat 204 rises. The fourth sub-cavity 2032 is connected to the second sub-cavity 1012. The camera body 3 is connected to the third seat 204. When the third seat 204 rises to its highest position relative to the first seat 201, it forms a transmission connection with the turbine 4 so that it can rotate relative to the first seat 201 under the drive of the turbine 4.

[0041] The first seat 201 is disposed in the first receiving cavity 101 of the base 1, and its outer peripheral wall is in sliding fit with the inner peripheral wall of the first receiving cavity 101, so that the first seat 201 can move up and down relative to the base 1 along the depth direction of the first receiving cavity 101. The first seat 201 divides the first receiving cavity 101 into a first sub-cavity 1011 and a second sub-cavity 1012, wherein the first sub-cavity 1011 is located above the first seat 201, and the second sub-cavity 1012 is located below the first seat 201.

[0042] The second base 202 can be integrally formed with the first base 201, or it can be fixed to the inner wall of the first base 201 by means of threaded connection, snap-fit, or welding. A second receiving cavity 203 is formed between the second base 202 and the first base 201. The second receiving cavity 203 is located inside the first base 201 and outside the second base 202. The turbine 4 is rotatably connected to the second base 202; specifically, a rotating shaft or bearing seat can be provided on the second base 202, and the turbine 4 can be mounted on the rotating shaft or bearing seat by bearing, so that the turbine 4 can rotate about its own axis relative to the second base 202.

[0043] The third seat 204 is disposed in the second receiving cavity 203. A sliding fit is formed between the outer peripheral wall of the third seat 204 and the inner peripheral wall of the second receiving cavity 203, allowing the third seat 204 to move up and down relative to the first seat 201 and the second seat 202 along the depth direction of the second receiving cavity 203. The third seat 204 divides the second receiving cavity 203 into two independent spaces: a third sub-cavity 2031 and a fourth sub-cavity 2032. The volumes of the third sub-cavity 2031 and the fourth sub-cavity 2032 change in opposite directions as the third seat 204 moves up and down. Specifically, when the third seat 204 descends relative to the second seat 202, the volume of the third sub-cavity 2031 increases, and the volume of the fourth sub-cavity 2032 decreases; when the third seat 204 rises relative to the second seat 202, the volume of the third sub-cavity 2031 decreases, and the volume of the fourth sub-cavity 2032 increases. The fourth sub-chamber 2032 is connected to the second sub-chamber 1012. This connection can be achieved by opening a communication hole or airway on the second seat 202, or by the gap between the second seat 202 and the first seat 201.

[0044] The camera body 3 is connected to the third base 204. When the third base 204 moves up and down in the second receiving cavity 203, the camera body 3 moves up and down synchronously with the third base 204.

[0045] When the third seat 204 rises to its highest position relative to the first seat 201, it forms a transmission connection with the turbine 4. This transmission connection means that motion and torque can be transmitted between the third seat 204 and the turbine 4. Specifically, the rotational motion of the turbine 4 can drive the third seat 204 to rotate through this transmission connection, thereby causing the camera body 3 connected to the third seat 204 to rotate. This transmission connection can be achieved by the meshing of teeth on the third seat 204 and teeth on the turbine 4, by the contact of friction surfaces on the third seat 204 and friction surfaces on the turbine 4 to achieve frictional transmission, or by torque transmission between the third seat 204 and the turbine 4 through splines, end face teeth, or other separable engagement structures. When the third seat 204 is not in its highest position, there is no transmission connection between the third seat 204 and the turbine 4; they are independent of each other, and the rotation of the turbine 4 is not transmitted to the third seat 204.

[0046] The following describes the operation of the camera assembly 1000, which includes the movable base 2. The camera assembly 1000 in its initial state is as follows: Figure 1 and Figure 2As shown. When external gas is supplied into the second sub-chamber 1012 through the second gas supply channel 103, the gas pressure in the second sub-chamber 1012 increases. This gas pressure exerts an upward thrust on the bottom surface of the first seat 201, driving the first seat 201 to rise relative to the base 1. As the first seat 201 rises, the second seat 202 fixed inside it and the third seat 204 disposed in the second receiving cavity 203 rise synchronously. At this time, since the third seat 204 has not yet formed a transmission connection with the turbine 4, the camera body 3 rises as a whole with the first seat 201, the second seat 202, and the third seat 204 without rotating. Figure 3 As shown, when the first seat 201 rises to its highest position, it stops moving, but external gas continues to be supplied to the second sub-chamber 1012. Since the fourth sub-chamber 2032 is connected to the second sub-chamber 1012, the gas in the second sub-chamber 1012 will enter the fourth sub-chamber 2032. As gas continues to be supplied to the fourth sub-chamber 2032, the gas pressure in the fourth sub-chamber 2032 increases. This gas pressure exerts an upward thrust on the bottom surface of the third seat 204, driving the third seat 204 to continue rising relative to the second seat 202. Figure 4 and Figure 5 As shown, when the third seat 204 rises to its highest position, the third seat 204 forms a transmission connection with the turbine 4. The rotational motion of the turbine 4 can be transmitted to the third seat 204 through this transmission connection, causing the third seat 204 to rotate relative to the first seat 201, and in turn causing the camera body 3 to rotate relative to the first seat 201.

[0047] During the aforementioned process, the overall rise of the movable seat 2 is driven by the air pressure within the second sub-chamber 1012, and the further rise of the third seat 204 relative to the first seat 201 is driven by the air pressure within the fourth sub-chamber 2032, with the gas in the fourth sub-chamber 2032 originating from the second sub-chamber 1012. In other words, the same external gas supplied to the second sub-chamber 1012 first drives the first seat 201 to rise, and then, after reaching its final position, continues to drive the third seat 204 to rise and engage with the turbine 4, ultimately achieving the rotation of the camera body 3.

[0048] This embodiment utilizes a two-stage lifting structure of the first base 201 and the third base 204 to spatially separate the extension action of the camera body 3 from the transmission engagement action. The stroke of the first base 201 in the first receiving cavity 101 only needs to meet the requirement of pushing the camera body 3 from its storage position to the outside of the display device, and the relative stroke of the third base 204 in the second receiving cavity 203 only needs to meet the requirement of forming a transmission connection between the third base 204 and the turbine 4. As a result, the depth of the first receiving cavity 101 required for the base 1 can be reduced, and the base 1 can be designed to be more compact in the height direction, which is beneficial to providing more space for other components inside the display device and adapting to the development trend of thinner and lighter display devices. At the same time, this solution realizes the automated action sequence of extension followed by rotation through pneumatic means, without the need for a separate motor or complex electronic control timing logic, resulting in a simple structure and high reliability.

[0049] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7 The camera assembly 1000 also includes a first magnetic member 5 and a second magnetic member 6; the first magnetic member 5 is disposed on the base 1, and the second magnetic member 6 is disposed on the first seat 201; when the first seat 201 rises to the highest position relative to the base 1, the first magnetic member 5 and the second magnetic member 6 attract each other.

[0050] At least one of the first magnetic attractor 5 and the second magnetic attractor 6 is a permanent magnet or electromagnet, and the other is a permanent magnet or a component that can be attracted by magnetic force. When the first seat 201 rises to its highest position relative to the base 1, the first magnetic attractor 5 and the second magnetic attractor 6 attract each other to maintain the positional stability of the first seat 201 at its highest position.

[0051] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7 The camera assembly 1000 also includes a third magnetic member 7 and a fourth magnetic member 8; the third magnetic member 7 is disposed on the first base 201, and the fourth magnetic member 8 is disposed on the third base 204; when the third base 204 rises to its highest position relative to the first base 201, the third magnetic member 7 and the fourth magnetic member 8 attract each other.

[0052] At least one of the third magnetic attractor 7 and the fourth magnetic attractor 8 is a permanent magnet or electromagnet, and the other is a permanent magnet or a component that can be attracted by magnetic force. When the third seat 204 rises to its highest position relative to the first seat 201, the third magnetic attractor 7 and the fourth magnetic attractor 8 attract each other to maintain the positional stability of the third seat 204 at its highest position.

[0053] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7 The camera assembly 1000 also includes a fifth magnetic member 9 and a sixth magnetic member 10; the fifth magnetic member 9 is disposed on the turbine 4, and the sixth magnetic member 10 is disposed on the third seat 204; when the third seat 204 rises to its highest position relative to the first seat 201, the fifth magnetic member 9 and the sixth magnetic member 10 attract each other so that the turbine 4 and the third seat 204 form a transmission connection.

[0054] When the third seat 204 rises to its highest position relative to the first seat 201, the fifth magnetic chuck 9 and the sixth magnetic chuck 10 approach each other and face each other, generating a magnetic attraction force. Under the action of this magnetic attraction force, a transmission connection is formed between the turbine 4 and the third seat 204. Unlike transmission methods such as gear meshing and spline engagement that require strict alignment and precision machining, the magnetic attraction transmission method in this embodiment has lower requirements for the fitting accuracy between the turbine 4 and the third seat 204. The two do not need to be precisely aligned and can automatically attract each other under the action of magnetic attraction force. Even if there is a certain positional deviation between the two in the axial or circumferential direction, the magnetic attraction force can make the two adjust to the attraction state on their own. Thus, while ensuring that the transmission connection between the turbine 4 and the third seat 204 is properly established, the machining accuracy requirements of the parts and the assembly difficulty are reduced.

[0055] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7 The second seat 202 is provided with a first air passage 2021, and the two ends of the first air passage 2021 are connected to the second sub-chamber 1012 and the turbine 4 respectively. The first air passage 2021 is provided with a first valve 11, which allows gas to flow unidirectionally from the second sub-chamber 1012 to the turbine 4 when the first valve 11 is open.

[0056] The first valve 11 can be a one-way valve. By controlling the opening and closing timing of the first valve 11, it is possible to determine when the turbine 4 starts to rotate, that is, to determine the timing of the rotation of the camera body 3 during the lifting and lowering process, so that the lifting and lowering actions and the rotation actions can be controlled independently in terms of timing. When the camera body 3 needs to rotate, the first valve 11 is opened, and gas flows through the first air passage 2021 to the turbine 4 to drive its rotation; when rotation is not needed, the first valve 11 is closed, and gas no longer flows through the turbine 4, and the turbine 4 and the camera body 3 maintain their current angle. In addition, the one-way flow characteristic of the first valve 11 can also prevent the high-pressure gas at the turbine 4 from flowing back into the second sub-chamber 1012, ensuring the stability of the lifting and lowering movement of the movable seat 2.

[0057] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7The second seat 202 is provided with a second air passage 2022, and the two ends of the second air passage 2022 are connected to the turbine 4 and the first air passage 2021 respectively. The second air passage 2022 is provided with a second valve 12, which allows gas to flow unidirectionally from the turbine 4 to the first air passage 2021 when the second valve 12 is open.

[0058] In this embodiment, the first air passage 2021 and the second air passage 2022 together constitute a gas circulation path. External gas flows from the second sub-chamber 1012 into the turbine 4 through the first air passage 2021. After passing through the turbine 4, the gas flows back to the first air passage 2021 through the second air passage 2022, and merges with the gas in the first air passage 2021 to continue participating in the next cycle. This circulation path allows the airflow to flow continuously and stably in a preset direction, thereby driving the turbine 4 to rotate stably in the preset direction. At the same time, it can prevent gas from accumulating in the chamber space where the turbine 4 is located, forming back pressure and hindering the rotation of the turbine 4.

[0059] When it is necessary to discharge the gas in the area where turbine 4 is located under subsequent operating conditions, the second valve 12 can be opened separately to allow the gas in the area where turbine 4 is located to be discharged through the second air passage 2022. By controlling the opening and closing of the second valve 12, the residual gas in its chamber can be released after turbine 4 stops rotating. The second valve 12 can be a one-way valve to ensure unidirectional flow of gas in the second air passage 2022, preventing the gas in the first air passage 2021 from flowing back into the area where turbine 4 is located along the second air passage 2022 and interfering with the normal rotation of turbine 4.

[0060] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7 The second seat 202 is provided with a third airway 2023, and the two ends of the third airway 2023 are connected to the first airway 2021 and the fourth sub-chamber 2032, respectively.

[0061] The cross-sectional area of ​​the third air passage 2023 is much smaller than that of the second sub-chamber 1012. When external gas is supplied into the second sub-chamber 1012, due to the limited flow capacity of the third air passage 2023, the gas preferentially accumulates in the second sub-chamber 1012, causing the gas pressure in the second sub-chamber 1012 to gradually increase and push the first seat 201 upward. When the first seat 201 rises to its highest position and can no longer rise, the gas pressure in the second sub-chamber 1012 continues to rise. When the pressure rises to a level sufficient to drive gas through the third air passage 2023 at a certain flow rate, the gas in the second sub-chamber 1012 will enter the fourth sub-chamber 2032 through the third air passage 2023 to drive the third seat 204 to rise relative to the first seat 201. Thus, by setting the third air passage 2023, a timing control is achieved that prioritizes driving the first seat 201 to rise and then drives the third seat 204 to rise, without the need for additional valves or electrical control components, resulting in a simple structure and high reliability.

[0062] In addition, during the process of the third seat 204 and the camera body 3 descending and resetting, the gas in the fourth sub-chamber 2032 can also be discharged in reverse through the third airway 2023 to provide a gas discharge passage for the third seat 204 during the resetting process.

[0063] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7 The second seat 202 is provided with a fourth air passage 2024, and the two ends of the fourth air passage 2024 are connected to the first air passage 2021 and the third sub-chamber 2031 respectively. The fourth air passage 2024 is provided with a third valve 13, which allows gas to flow unidirectionally from the first air passage 2021 to the third sub-chamber 2031 when the third valve 13 is open.

[0064] like Figure 4 and Figure 5As shown, when the third seat 204 and camera body 3 need to be lowered and reset, the first valve 11 is closed, and the external gas is switched to be supplied to the first sub-chamber 1011 through the first air supply channel 102, while the second air supply channel 103 stops supplying gas. At this time, the air pressure in the second sub-chamber 1012 gradually decreases, and the first seat 201 descends relative to the base 1 under its own weight and the air pressure in the first sub-chamber 1011. When the first seat 201 descends, the volume of the second sub-chamber 1012 is compressed, at which point the third valve 13 can be opened, and the gas in the second sub-chamber 1012 will enter the third sub-chamber sequentially through the first air channel 2021 and the fourth air channel 2024. The gas enters the third sub-chamber 2031 and pushes the third seat 204 down relative to the first seat 201. During the descent of the third seat 204, the volume of the fourth sub-chamber 2032 is compressed, and the gas in the fourth sub-chamber 2032 is discharged to the first airway 2021 via the third airway 2023. The discharged gas can merge with the airflow in the first airway 2021 and continue to enter the third sub-chamber 2031 via the fourth airway 2024, so as to continuously drive the third seat 204 down relative to the first seat 201. Thus, the first seat 201, the third seat 204 and the camera body 3 are lowered and reset.

[0065] The third valve 13 can be a one-way valve to prevent gas in the third sub-chamber 2031 from flowing back to the first airway 2021 via the fourth airway 2024, ensuring that the gas flows in a preset direction. The third valve 13 can also control the timing of the descent of the third seat 204. That is, by controlling the opening and closing of the third valve 13, it can be determined at any time during the descent of the first seat 201 whether the third seat 204 begins to descend.

[0066] In one embodiment, refer to Figures 1 to 5 and for reference Figure 6 and Figure 7 The second seat 202 is provided with a fifth air passage 2025; when the third seat 204 is in the highest position relative to the first seat 201, the two ends of the fifth air passage 2025 are connected to the fourth sub-chamber 2032 and the first air passage 2021 respectively; the fifth air passage 2025 is provided with a fourth valve 14, which allows gas to flow unidirectionally from the fourth sub-chamber 2032 to the first air passage 2021 when the fourth valve 14 is open.

[0067] Based on the previous embodiment, such as Figure 4 and Figure 5As shown, when the third seat 204 is in its highest position and needs to descend and reset, the external gas is switched to be supplied to the first sub-chamber 1011 through the first gas supply channel 102, the second gas supply channel 103 stops supplying gas, the first valve 11 is closed, and the third valve 13 is opened, so that the gas in the second sub-chamber 1012 enters the third sub-chamber 2031 in sequence through the first air passage 2021 and the fourth air passage 2024. Since there is a large amount of gas accumulated in the fourth sub-chamber 2032 at this time, it will generate an upward air pressure force on the third seat 204. This air pressure force is opposite in direction to the downward air pressure force exerted by the gas in the third sub-chamber 2031 on the third seat 204. The two cancel each other out and may form an air cushion effect, which may cause the third seat 204 to be unable to start the descent movement normally.

[0068] Based on the above problems, this embodiment further includes a fifth air passage 2025. By opening the fourth valve 14 in the fifth air passage 2025, the high-pressure gas in the fourth sub-chamber 2032 can be discharged to the first air passage 2021 via the fifth air passage 2025, reducing the air pressure in the fourth sub-chamber 2032 and creating a pressure difference with the third sub-chamber 2031. This allows the third seat 204 to smoothly initiate its descent under the pressure of the air in the third sub-chamber 2031. When the third seat 204 descends to a certain height, a stable pressure difference is formed between the fourth sub-chamber 2032 and the third sub-chamber 2031, ensuring the subsequent stable descent of the third seat 204. At this point, it is unnecessary to continue discharging the gas from the fourth sub-chamber 2032 to the first air passage 2021 via the fifth air passage 2025. Figure 2 As shown, at this time, the third seat 204 has also passed the fifth airway 2025, so that the fifth airway 2025 is no longer connected to the fourth sub-chamber 2032, and the fourth valve 14 can also be closed.

[0069] In one embodiment, refer to Figure 1 , Figure 3 and Figure 4 and for reference Figure 6 and Figure 7 The exhaust passage 104 is provided with a fifth valve 15. When the fifth valve 15 is open, it allows gas to flow unidirectionally from the first sub-chamber 1011 and the second sub-chamber 1012 to the heat dissipation area 2100.

[0070] The fifth valve 15 can be a one-way valve. When the air pressure in the first sub-chamber 1011 or the second sub-chamber 1012 is higher than the air pressure on the side of the heat dissipation area 2100, the fifth valve 15 opens, and the gas in the first sub-chamber 1011 and the second sub-chamber 1012 can be discharged to the heat dissipation area 2100 through the exhaust channel 104; when the air pressure on the side of the heat dissipation area 2100 is higher than the air pressure in the first sub-chamber 1011 or the second sub-chamber 1012, the fifth valve 15 closes, which can prevent external gas or gas near the heat dissipation area 2100 from flowing back into the first receiving cavity 101 and interfering with the normal lifting and lowering movement of the movable seat 2.

[0071] In one embodiment, refer to Figure 1 , Figure 3 and Figure 4 and for reference Figure 6 and Figure 7 The camera assembly 1000 also includes a seventh magnetic member 16 and an eighth magnetic member 17; the seventh magnetic member 16 is disposed on the base 1, and the eighth magnetic member 17 is disposed on the movable seat 2; when the movable seat 2 descends to the lowest position relative to the base 1, the seventh magnetic member 16 and the eighth magnetic member 17 attract each other.

[0072] At least one of the seventh magnetic chuck 16 and the eighth magnetic chuck 17 is a permanent magnet or electromagnet, and the other is a permanent magnet or a component that can be attracted by magnetic force. When the movable seat 2 descends to its lowest position relative to the base 1, the seventh magnetic chuck 16 and the eighth magnetic chuck 17 approach each other and face each other, generating a magnetic attraction between them. Under the action of this magnetic attraction, the movable seat 2 is held in its lowest position. As a result, the camera body 3 can stably maintain its retracted state without continuous air supply when in the stored state, which helps to reduce energy consumption.

[0073] In one embodiment, refer to Figure 1 , Figure 3 and Figure 4 and for reference Figure 6 and Figure 7 The camera assembly 1000 also includes a gear pump 18 and a reversing valve 19; the base 1 is provided with an air supply main 105, one end of which is connected to the outside through the gear pump 18, and the reversing valve 19 is located between the other end of the air supply main 105 and the first air supply channel 102 and the second air supply channel 103; the gear pump 18 is used to control the supply of external gas into the air supply main 105, and the reversing valve 19 is used to control the connection between the air supply main 105 and one of the first air supply channel 102 and the second air supply channel 103.

[0074] When the movable seat 2 needs to rise, the reversing valve 19 connects the main air supply line 105 to the second air supply channel 103. The gas output from the gear pump 18 enters the second sub-chamber 1012 through the main air supply line 105 and the second air supply channel 103. When the movable seat 2 needs to descend, the reversing valve 19 connects the main air supply line 105 to the first air supply channel 102. The gas output from the gear pump 18 enters the first sub-chamber 1011 through the main air supply line 105 and the first air supply channel 102. Through the cooperation of the gear pump 18 and the reversing valve 19, precise control of the air supply direction and air volume can be achieved, thereby improving the control accuracy of the lifting speed of the movable seat 2 and the rotation angle of the camera body 3.
