Description

Technical Field

[0001] The present invention relates to the technical field of camera equipment, in particular to an adsorption-type anti-dumping camera. Background Art

[0002] A camera is an image acquisition device that converts real scenes into electronic signals through an optical imaging system. Its working principle is based on an optical lens group that focuses light on the surface of a photosensitive element. The photosensitive element converts the light signal into a charge signal through the photoelectric effect, and then generates digital image data through an analog-to-digital converter. Finally, the image processor performs optimization processing such as noise reduction and color correction. As the core carrier of modern visual perception, cameras are widely used in real-time situational awareness of security monitoring systems, pathological image acquisition for telemedicine, dynamic traffic analysis for intelligent transportation, automated quality inspection for industrial production, and human-computer interaction interfaces in the consumer electronics field, becoming the basic visual neural node for building an intelligent digital ecosystem.

[0003] Suction cup rotatable cameras, due to their compact size and ease of installation, are widely deployed in scenarios requiring dynamic viewing angle adjustment and non-destructive installation, such as in-vehicle mobile surveillance, glass curtain wall inspections, temporary security deployments, and mobile smart home devices. This is due to their need for dynamic environmental perception. For example, in-vehicle scenarios, camera angles must be adjusted in sync with vehicle steering, security systems require periodic scanning of blind spots, and smart homes require real-time tracking of human activity. This requires frequent rotation during operation. However, the mechanical movement of the rotating mechanism continuously disrupts the vacuum seal between the suction cup and the contact surface. Torque transmission causes micro-deformation at the edge of the suction cup, and repeated friction triggers interface slip, resulting in the formation of micro-air gaps at the adsorption interface and their gradual expansion, which ultimately causes nonlinear attenuation of the adsorption force. This inherent contradiction between motion function and structural stability makes the device prone to tipping over during rotation due to center of gravity shift and imbalance of adsorption force. Tipping over can easily cause damage to the mechanical structure of the camera body, especially the shift or breakage of precision optical components. At the same time, the interruption of visual coverage leads to the formation of monitoring blind spots, which will undermine the integrity of the security system and lead to missed event records. To this end, we propose an adsorption-type anti-tip camera. Summary of the Invention

[0004] One of the technical problems to be solved by this application is that micro-air gaps are formed on the adsorption interface and gradually expand, eventually causing the adsorption force to decay nonlinearly. This inherent contradiction between the motion function and the structural stability makes the device prone to tipping over during rotation due to the shift of the center of gravity and the imbalance of the adsorption force. The tipping over can easily cause damage to the mechanical structure of the camera body, especially the shift or breakage of the precision optical components. At the same time, the interruption of visual coverage leads to the formation of a monitoring blind spot, which will destroy the integrity of the security system and cause the loss of event records.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: an adsorption type anti-dumping camera, comprising a supporting base 1 and a rotating base 2 rotatably connected to the supporting base 1, and a camera device body 3 is provided on the rotating base 2, a plurality of connecting tubes 4 are installed in the supporting base 1, and a negative pressure suction cup 5 is provided on each of the plurality of connecting tubes 4, and an air pressure sensor 6 is provided in the connecting tube 4, a fixing unit 7 connected to the connecting tube 4 is provided on the supporting base 1, and the plurality of connecting tubes 4 and the negative pressure suction cup 5 connected to the connecting tube 4 are fixed to the supporting base 1 by the fixing unit 7, and a pressure compensation unit 10 connected to the connecting tube 4 and the negative pressure suction cup 5 is provided in the supporting base 1, so that when the air pressure sensor 6 detects an abnormal pressure in the negative pressure suction cup 5, the pressure compensation unit 10 is driven to apply downward pressure to the connecting tube 4 and the negative pressure suction cup 5, so that the negative pressure suction cup 5 re-attaches to the adsorption surface, and at the same time, the air inside the negative pressure suction cup 5 is sucked to restore the negative pressure.

[0032] The fixing unit 7 includes a mounting member 8 arranged on the supporting seat 1, and the mounting member 8 is used to fix multiple connecting tubes 4 and the negative pressure suction cup 5 on the supporting seat 1. A pressing member 9 is provided on the mounting member 8, which is used to press the negative pressure suction cup 5 when the supporting seat 1 is placed to form negative pressure to fix the camera device body 3.

[0033] The mounting member 8 includes a fixing groove 81 opened in the supporting seat 1, and a circular plate 82 is arranged in the fixing groove 81. The circular plate 82 is slidably connected to multiple connecting tubes 4, and the multiple connecting tubes 4 are distributed in a circular array on the circular plate 82. A limiting plate 83 is provided at one end of the connecting tube 4 away from the negative pressure suction cup 5.

[0034] The circular array distribution design of multiple small negative pressure suction cups 5 forms a redundant adsorption structure, which significantly reduces the risk of overall detachment due to the failure of a single suction cup. At the same time, the negative pressure suction cups 5 evenly distributed circumferentially can work together to offset the overturning moments generated in different directions when the camera dynamically rotates or shifts, thereby ensuring that the equipment can still maintain stable adsorption under complex motion conditions and maintain the stability of the camera during shooting. The layout of the circular array makes the contact pressure distribution between each suction cup and the bearing surface more balanced, effectively avoiding the adsorption failure problem caused by local stress concentration of a traditional single suction cup.

[0035] The pressing member 9 includes a supporting plate 91 arranged in the fixed groove 81, and a pushing motor 92 is provided on the supporting plate 91. A rotating shaft 93 is rotatably provided on the circular plate 82, and one end of the rotating shaft 93 is connected to the power output shaft of the pushing motor 92. A rotating plate 94 is provided at the other end of the rotating shaft 93. A plurality of pushing blocks 95 are provided on the rotating plate 94, and the plurality of pushing blocks 95 are all wedge-shaped blocks. A pushing rod 96 used in conjunction with the pushing block 95 is provided on the plurality of connecting tubes 4.

[0036] When placing the camera equipment, the negative pressure suction cup 5 is first placed against the contact surface, and then the pushing motor 92 is started. The pushing motor 92 drives the rotating shaft 93 to rotate synchronously. The rotation of the rotating shaft 93 also drives the rotating plate 94 to rotate, and simultaneously drives the multiple pushing blocks 95 provided on the rotating plate 94 to rotate around the rotating shaft 93. Because the pushing block 95 is a wedge-shaped block, when the pushing block 95 rotates, it presses the pushing rod 96 and the connecting tube 4 connected to the pushing rod 96 downward. The downward movement of the connecting tube 4 further presses the negative pressure suction cup 5 to complete the fixation of the camera equipment. By driving the mechanical linkage between the rotating shaft 93 and the rotating plate 94 driven by the pushing motor 92, the wedge-shaped pushing block 95 converts the circumferential motion into the linear downward force of the pushing rod 96 during the rotation process, thereby achieving the synchronous pressing and fixing of the multiple negative pressure suction cups 5, effectively improving the installation efficiency and ensuring that the force on each suction cup is uniform. The integrated mechanical transmission design avoids the complexity of manual point-by-point pressing. At the same time, the rigid linkage structure enhances the pressure stability, so that the suction cups and the supporting surface quickly form a uniform and reliable negative pressure adsorption state, significantly optimizing the convenience and fixing strength of equipment deployment.

[0037] The pressure compensation unit 10 includes a negative pressure member 11 arranged in the fixed groove 81, and the negative pressure member 11 is used to provide negative pressure for sucking the air inside the negative pressure suction cup 5. A compensation member 12 is provided on the supporting plate 91. When the air pressure sensor 6 detects that the pressure in the negative pressure suction cup 5 is abnormal, the compensation member 12 drives the push block 95 to apply downward pressure to the push rod 96, so that the loose negative pressure suction cup 5 is re-attached to the adsorption surface, and the negative pressure member 11 is synchronously connected to the negative pressure suction cup 5. A power member 13 is provided on the supporting plate 91, and the power member 13 is used to provide power for the operation of the negative pressure member 11. A separation member 14 is provided on the negative pressure member 11 to control the start and stop of the power member 13.

[0038] The negative pressure member 11 includes a fixed plate 111 provided on the carrier plate 91, a fixed plate 2 113 is slidably provided on the carrier plate 91, an expansion airbag 112 is provided between the fixed plate 111 and the fixed plate 2 113, a push spring 114 is provided in the expansion airbag 112, a positioning plate 115 is provided on the carrier plate 91, a switching chamber 116 is provided on the positioning plate 115, a switching plate 117 is provided in the switching chamber 116, a switching plate 2 118 is rotatably provided in the switching chamber 116 to fit with the switching plate 117, and the switching Both plate 117 and switching plate 2 118 are provided with docking grooves 119, and a synchronization chamber 1110 is provided on the side of the supporting plate 91 opposite to the circular plate 82. The synchronization chamber 1110 is connected to multiple connecting pipes 4 through hoses. The switching chamber 116 is located on both sides of switching plate 117 and switching plate 2 118, and is respectively provided with guide pipe 1 1111 and guide pipe 2 1112, and the guide pipe 1 1111 is connected to the expansion airbag 112, and the guide pipe 2 1112 is connected to the synchronization chamber 1110, and the guide pipe 1 1111 and guide pipe 2 1112 are both hoses.

[0039] When the camera rotates normally, the gas in the expansion airbag 112 is extracted to keep the expansion airbag 112 in a compressed state. Under the action of the air pressure, the second fixed plate 113 moves toward the first fixed plate 111 and simultaneously squeezes the push spring 114 in the expansion airbag 112, so that the expansion airbag 112 is compressed. When the air pressure sensor 6 detects the pressure change in the negative pressure suction cup 5, the rotating shaft 93 will work synchronously. When the rotating shaft 93 works, it drives the linkage shaft 121 to rotate synchronously through the synchronous pulley 122 and the synchronous belt 123. When the linkage shaft 121 rotates, it drives the switching gear 125 provided thereon to rotate. When the switching gear 125 rotates, it drives the switching shaft 124 to rotate. The rotation of the switching shaft 124 drives the switching plate When the second switch plate 118 rotates, the docking groove 119 on the second switch plate 118 coincides with the docking groove 119 on the first switch plate 117. At this time, the expansion airbag 112 is connected to the connecting pipe 4 and the negative pressure suction cup 5 through the second guide pipe 1112 and the synchronization chamber 1110. At the same time, the negative pressure in the expansion airbag 112 sucks the gas in the negative pressure suction cup 5, so that the negative pressure suction cup 5 is re-fixed on the adsorption surface. When the rotating shaft 93 rotates, the rotating plate 94 and the pushing block 95 are driven to rotate again, squeezing the negative pressure suction cup 5 that bounces up after being loosened, so that it fits into the contact surface again, thereby ensuring that when the gas in the negative pressure suction cup 5 is sucked, the negative pressure suction cup 5 is isolated from the external environment, thereby improving the stability during reinforcement.

[0040] When the inflatable airbag 112 is compressed, the pushing spring 114 is simultaneously compressed and stores elastic potential energy, and generates an outward restoring force, which pushes the inflatable airbag 112 to expand. When the inflatable airbag 112 is connected to the loose negative pressure suction cup 5, the two form a closed system, and the pushing spring 114 releases energy, thereby pushing the inflatable airbag 112 to increase in volume. According to the gas law (PV = nRT), if the temperature (T) is approximately constant and the total amount of gas (n) is unchanged, the increase in volume (V) will cause the pressure (P) to decrease. At this time, the pressure in the inflatable airbag 112 is lower than that in the negative pressure suction cup 5, and the gas passively flows from the negative pressure suction cup 5 to the inflatable airbag 112, forming a negative pressure in the negative pressure suction cup 5. At the same time, the rotating plate 94 and the pushing block 95 squeeze the loose negative pressure suction cup 5, prompting it to re-fit the contact surface and restore the sealing state.

[0041] The expansion airbag 112 is pre-compressed by the rotation of the camera during normal operation. When the rotation of the camera causes the negative pressure suction cup 5 to loosen, the air pressure sensor 6 triggers a signal to drive the motor 92 to drive the rotating shaft 93 to rotate, and the switching shaft 124 is driven to rotate through the synchronous pulley 122 and the gear set to ensure the alignment accuracy of the guide channel and the synchronization of the sealing surface closing, avoiding pressure leakage caused by timing deviation. At the same time, the expansion airbag 112 forms a negative pressure reserve in the pre-compression state. When the suction cup is loose, the internal negative pressure quickly sucks the residual air in the suction cup through the guide channel. Gas, at the same time, the mechanical downward pressure forces the edge of the suction cup and the bearing surface to form a temporary sealing area, blocking the infiltration of external air, and maximizing the efficiency of negative pressure reconstruction. During the suction cup resetting and fitting stage, the mechanical downward pressure takes precedence over the negative pressure suction action to ensure that the suction cup and the bearing surface form a preliminary physical seal, providing a closed cavity condition for subsequent air pressure adjustment. The timing coupling of mechanical reset and air pressure adjustment ensures that the suction cup is always in a closed state during the reinforcement process, significantly improving the self-repair efficiency and system anti-interference ability under dynamic disturbances, and taking into account both response speed and reinforcement reliability.

[0042] The compensation member 12 includes a linkage shaft 121 rotatably provided on the carrier plate 91, and the linkage shaft 121 passes through the carrier plate 91. A synchronous pulley 122 is provided on the linkage shaft 121 and the rotating shaft 93. A synchronous belt 123 is sleeved on the synchronous pulley 122. A switching shaft 124 is rotatably provided on the switching bin 116, and the switching shaft 124 is connected to the switching plate 2 118. The switching shaft 124 and the linkage shaft 121 are both provided with switching gears 125 that mesh with each other.

[0043] As the rotating shaft 93 rotates, it drives the rotating plate 94 and the pushing block 95 to rotate, squeezing the negative pressure suction cup 5 that has bounced up after being loosened, so that it fits back into the contact surface. The downward pressure action forces the edge of the suction cup to fit tightly against the bearing surface, forming a temporary physical sealing area, blocking the path for external air to infiltrate, creating a closed environment for subsequent suction, and avoiding adsorption failure due to air leakage during the negative pressure establishment process.

[0044] The power part 13 includes a mounting plate 131 arranged on the supporting plate 91, a rotating plate 132 is rotatably arranged on the mounting plate 131, a connecting rod 133 is rotatably arranged on the rotating plate 132, a circulation chamber 134 is arranged on the side of the fixed plate 111 away from the expansion airbag 112, a piston plate 135 is slidingly arranged in the circulation chamber 134, the piston plate 135 is rotatably connected to the connecting rod 133, a one-way air outlet valve 137 is arranged on the side wall of the circulation chamber 134, a one-way air inlet valve 136 is arranged on the fixed plate 111, and the circulation chamber 134 is connected to the expansion airbag 112 through the one-way air inlet valve 136.

[0045] The disengagement member 14 includes a power shaft 141 arranged on the supporting seat 1, and the power shaft 141 is connected to the rotating seat 2. A docking rod 143 is provided on the rotating plate 132, and the docking rod 143 is a polygonal rod. A sleeve rod 142 is slidably provided on the power shaft 141, and a locking groove 144 is provided on the sleeve rod 142 for sliding cooperation with the docking rod 143. A lifting plate 145 is provided on the sleeve rod 142, and a wedge-shaped lifting block 146 is provided on the lifting plate 145. An L-shaped plate 147 used in conjunction with the lifting block 146 is provided on the fixed plate.

[0046] When the rotating seat 2 drives the camera to rotate during operation, it drives the power shaft 141 connected to the rotating seat 2 to rotate synchronously. When the power shaft 141 rotates, it drives the sleeve rod 142 to rotate, and then drives the rotating plate 132 to rotate synchronously through the positioning groove 144 and the docking rod 143. When the rotating plate 132 rotates, it drives the connecting rod 133 to rotate, thereby pushing the piston plate 135 to slide in the circulation chamber 134, thereby sucking the gas in the expansion airbag 112. During the continuous compression process of the expansion airbag 112, the fixed plate 2 113 gradually approaches the fixed plate 135. When the second fixing plate 113 is reset, the L-shaped plate 147 is disengaged from the lifting block 146, and the sleeve rod 142 falls under the action of gravity and re-docking with the docking rod 143.

[0047] Through the mechanical linkage between the rotating seat 2 and the power shaft 141, the piston plate 135 is driven to suck gas from the expansion airbag 112, thereby achieving continuous compression of the airbag and resetting of the fixed plate; when the compression approaches the limit, the contact between the L-shaped plate 147 and the lifting block 146 forces the locking groove 144 to disengage from the docking rod 143, automatically cutting off the power transmission of the piston plate 135, and limiting the compression stroke of the expansion airbag 112 in a purely mechanical way, effectively avoiding structural damage or sealing failure caused by excessive compression. This design realizes autonomous start-stop control of pressure regulation with zero additional energy consumption, significantly improving the reliability and service life of the system in long-term dynamic working conditions.

[0048] Example 2: Please refer to Figure 11 The present invention provides a technical solution: an air storage tank 15 is provided on the supporting plate 91, an extrusion spring 16 is provided in the air storage tank 15, a piston plate 2 17 is slidably provided in the air storage tank 15, and the piston plate 2 17 is connected to the extrusion spring 16, the bottom end of the air storage tank 15 is connected to the one-way air outlet valve 137 on the circulation tank 134 through a hose, a conducting pipe 18 is provided at the bottom of the air storage tank 15, the conducting pipe 18 passes through the supporting plate 91, and an electric-controlled pressure valve 19 is provided in the conducting pipe 18.

[0049] The gas extracted from the circulation chamber 134 is discharged into the air storage chamber 15 through the one-way air outlet valve 137 and the hose. After being discharged into the air storage chamber 15, the gas squeezes the piston plate 2 17 and simultaneously compresses the extrusion spring 16 through the piston plate 2 17. When the air pressure in the air storage chamber 15 reaches a preset threshold, the electronically controlled pressure valve 19 detects that the pressure reaches the standard and opens, so that the gas in the air storage chamber 15 is sprayed into the fixed groove 81 through the conducting pipe 18, thereby discharging the dust at the bottom of the supporting seat 1 to avoid affecting the stability of the negative pressure suction cup 5.

[0050] The gas discharged from the circulation chamber 134 is introduced into the gas storage chamber 15 through the one-way air outlet valve 137, and the air pressure is used to push the piston plate 2 17 to compress the extrusion spring 16 to achieve temporary energy storage; when the pressure in the gas storage chamber 15 reaches the preset threshold, the electronically controlled pressure valve 19 automatically opens, allowing the high-pressure gas to be ejected in a direction through the conducting pipe 18, effectively removing the dust accumulated at the bottom of the supporting seat 1. This design forms a self-sustaining closed-loop cleaning system, which can maintain the cleanliness of the adsorption interface of the negative pressure suction cup 5 to ensure adsorption stability.

[0052] The gas extracted from the circulation chamber 134 is discharged into the air storage chamber 15 through the one-way air outlet valve 137 and the hose. After being discharged into the air storage chamber 15, the gas squeezes the piston plate 2 17 and simultaneously compresses the extrusion spring 16 through the piston plate 2 17. When the air pressure in the air storage chamber 15 reaches a preset threshold, the electronically controlled pressure valve 19 detects that the pressure reaches the standard and opens, so that the gas in the air storage chamber 15 is sprayed into the fixed groove 81 through the conducting pipe 18, thereby discharging the dust at the bottom of the supporting seat 1 to avoid affecting the stability of the negative pressure suction cup 5.

[0053] The gas discharged from the circulation chamber 134 is introduced into the gas storage chamber 15 through the one-way air outlet valve 137, and the air pressure is used to push the piston plate 2 17 to compress the extrusion spring 16 to achieve temporary energy storage; when the pressure in the gas storage chamber 15 reaches the preset threshold, the electronically controlled pressure valve 19 automatically opens, allowing the high-pressure gas to be ejected in a direction through the conducting pipe 18, effectively removing the dust accumulated at the bottom of the supporting seat 1. This design not only maintains the cleanliness of the adsorption interface of the negative pressure suction cup 5 to ensure adsorption stability, but also improves the sustainability of the system through energy recycling.
