Description

Technical Field

[0001] The present application belongs to the technical field of industrial camera cleaning, and specifically relates to a dust prevention and cleaning device for an industrial camera. Background Art

[0002] Industrial cameras, also known as machine vision cameras, are digital cameras designed for industrial applications. They play a key role in machine vision systems, responsible for converting optical signals into orderly electrical signals, which directly affect the operation mode of the entire system. They are mainly used in automated production lines for object detection, classification, mark recognition and other automated control and auxiliary production processes, as well as product quality inspection, machine vision technology and logistics automation. Since industrial cameras are often used in factories, and the factory environment is relatively complex, the lenses of industrial cameras are often covered and blocked by dust, liquids, particles, etc., which affects the quality of the images collected by the industrial cameras, making it impossible to obtain accurate and high-definition images, which in turn affects the normal use of industrial cameras.

[0003] In order to ensure the normal use of industrial cameras, in the prior art, a rubber strip or a brush is usually provided at the lens of the industrial camera to directly clean the lens. When the rubber strip or the brush moves relative to the lens of the industrial camera, the rubber strip or the brush will rub against the lens, which will cause damage to the lens of the industrial camera, thereby affecting the service life of the industrial camera. Utility Model Content

[0004] The present application provides a dust prevention and cleaning device for an industrial camera to avoid damage to the lens, thereby ensuring the service life of the industrial camera.

[0005] The technical solution adopted in this application is:

[0006] A dustproof and cleaning device for an industrial camera comprises a shell having a accommodating cavity, a high-definition lens arranged in the accommodating cavity, a cleaning member arranged in the accommodating cavity and used for cleaning the high-definition lens, and a driving member for driving the cleaning member to move, wherein one end of the shell has a sampling port connected to the accommodating cavity, the industrial camera is arranged inside the accommodating cavity with its lens facing the sampling port, and the high-definition lens is located on the side of the lens of the industrial camera facing the sampling port.

[0007] By adopting the above technical solution, when the industrial camera is working, the scene outside the shell is collected by the industrial camera through the sampling port and the high-definition lens; because the industrial camera is arranged in the accommodating cavity, and the high-definition lens is arranged between the industrial camera and the sampling port, the dust outside the shell cannot pass through the high-definition lens and adhere to the lens, so that the dust can only adhere to the high-definition lens; when cleaning the high-definition lens, the driving member is started, and the driving member drives the cleaning member to make the cleaning member and the high-definition lens move relative to each other, and then the cleaning member cleans the high-definition lens, so that the industrial camera can obtain accurate and high-definition images to ensure the normal use of the industrial camera, while avoiding the situation where the cleaning member directly contacts the lens of the industrial camera and may cause damage to the lens, thereby ensuring the service life of the industrial camera.

[0008] Optionally, a transmission member is provided in the accommodating cavity, and the transmission member has a connecting section rotatably connected to the shell, a transmission end transmission-connected to the driving member, and an action end acting on the cleaning member. When the driving member is working, the transmission end rotates around the connecting section so that the action end drives the cleaning member to move in the first direction.

[0009] By adopting the above technical solution, when cleaning the high-definition lens, the driving member is started, and the driving member drives the transmission end, and then the transmission end swings around the connecting section, so that the action end also swings around the connecting section, so that the action end drives the cleaning member to move, so that the cleaning member cleans the high-definition lens. It can be understood that the reciprocating motion of the cleaning member in the first direction realizes the cleaning of the high-definition lens, thereby avoiding the existence of cleaning dead corners, and thus ensuring the camera quality of the industrial camera.

[0010] Optionally, a cleaning frame is provided in the accommodating cavity and is located on a side of the high-definition lens close to the sampling port. Guide grooves are provided on opposite sides of the cleaning frame along a first direction, and both ends of the cleaning member are respectively slidably connected to the guide grooves.

[0011] By adopting the above technical solution, when the cleaning member moves under the action of the driving member, the cleaning member and the guide groove slide relative to each other, so that the guide groove guides the movement of the cleaning member to increase the stability of the cleaning member, thereby ensuring the cleaning effect of the high-definition lens and ensuring the camera quality of the industrial camera.

[0012] Optionally, the guide groove has a straight section and a curved section that curves in a direction away from the high-definition lens, and a projection of the curved section toward the high-definition lens is located outside the high-definition lens.

[0013] By adopting the above technical solution, when the cleaning of the high-definition lens stops, the cleaning member moves to the curved section. Since the curved section is curved toward the high-definition lens and the projection toward the high-definition lens is located outside the high-definition lens, the cleaning member and the high-definition lens are avoided, thereby avoiding the cleaning member from being within the shooting range of the industrial camera, thereby ensuring the shooting quality of the industrial camera. At the same time, when the high-definition lens is replaced, the cleaning member is located in the curved section to separate the cleaning member from the high-definition glass, so that the cleaning member and the high-definition glass are avoided, thereby achieving the effect of facilitating the replacement of the high-definition glass.

[0014] Optionally, a through opening is provided on the side of the shell corresponding to the high-definition lens, and the high-definition lens enters the accommodating cavity through the through opening.

[0015] By adopting the above technical solution, the high-definition lens may be damaged due to the long-term friction between the cleaning piece and the high-definition lens. At this time, the high-definition lens can be taken out through the through port and then replaced to ensure the camera quality of the industrial camera.

[0016] Optionally, a lens frame is arranged outside the high-definition lens, and a rubber pad is arranged between the lens frame and the high-definition lens.

[0017] By adopting the above technical solution, a lens frame is provided on the outside of the high-definition lens, and a rubber pad is provided between the high-definition lens and the lens frame, so that the lens frame and the rubber pad have a shock-absorbing effect on the high-definition lens, and then the lens frame can protect the high-definition lens to avoid damage to the high-definition lens due to vibration of the shell, thereby further ensuring the camera quality of the industrial camera.

[0018] Optionally, a support frame is provided in the accommodating cavity and is located on a side of the lens frame close to the industrial camera, and the support frame is provided with an elastic member acting on the lens frame.

[0019] By adopting the above technical solution, after the lens frame equipped with the high-definition lens is installed in the shell, the elastic member applies elastic force to the lens frame to offset the gap between the lens frame and the support frame, thereby avoiding the possible shaking of the lens frame and further ensuring the camera quality of the industrial camera; at the same time, the elastic member acts on the lens frame to increase the connection stability between the lens frame and the shell.

[0020] Optionally, the support frame is provided with a receiving groove, the elastic member includes a contact portion provided at the notch of the receiving groove and an elastic portion provided inside the receiving groove and acting on the contact portion, and the lens frame is provided with a groove corresponding to the contact portion.

[0021] By adopting the above technical solution, when installing a lens frame equipped with a high-definition lens, the lens frame first contacts the contact part, and then pressure is applied to the lens frame so that the contact part compresses the elastic part under the action of the lens frame pressure, so that the contact part and the lens frame form an avoidance. When the groove on the lens frame moves to the position of the contact part, the contact part moves into the groove under the action of the elastic part, so that the contact part and the groove are plugged into each other to fix the lens frame, thereby increasing the stability of the lens frame.

[0022] Optionally, an air blowing member is provided in the accommodating cavity and is located on the side of the high-definition lens facing the sampling port, and the air blowing member has an air inlet and an air outlet connected to the air inlet and facing the sampling port.

[0023] By adopting the above technical solution, when the industrial camera is working, the external air supply part is connected to the air inlet, so that the air enters the blowing part through the air inlet, and the air is discharged through the air outlet. Since the air outlet is toward the sampling port, the air discharged through the air outlet moves toward the sampling port, so that an airflow from the inside to the outside is formed inside the shell, thereby preventing dust or particles outside the shell from entering the shell, thereby preventing dust from adhering to the high-definition lens, and at the same time preventing dust from affecting the image quality of the industrial camera at the sampling port.

[0024] Optionally, the sampling port is provided with a door body capable of relative movement with the sampling port and a power member driving the door body to move, so that the door body has an open state in which the sampling port is opened and a closed state in which the sampling port is closed.

[0025] By adopting the above technical solution, when the industrial camera stops working, the power part drives the door body to make the door body and the sampling port move relative to each other, and then the door body moves from an open state to a closed state to close the sampling port, thereby preventing dust or particles outside the shell from entering the shell, so as to ensure the cleanliness of the inside of the shell, and further ensure the camera quality of the industrial camera.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0027] 1. The dustproof and cleaning device in the present application includes a shell having a receiving cavity, a high-definition lens arranged in the receiving cavity, a cleaning member arranged in the receiving cavity and used for cleaning the high-definition lens, and a driving member for driving the cleaning member to move. One end of the shell has a sampling port connected to the receiving cavity, the industrial camera is arranged inside the receiving cavity and its lens faces the sampling port, and the high-definition lens is located on the side of the lens of the industrial camera facing the sampling port. Since the industrial camera is arranged in the receiving cavity and a high-definition lens is arranged between the industrial camera and the sampling port, dust outside the shell cannot pass through the high-definition lens and adhere to the lens, so that dust can only adhere to the high-definition lens; when cleaning the high-definition lens, the driving member is started, and the driving member drives the cleaning member to make the cleaning member and the high-definition lens move relative to each other, so that the cleaning member cleans the high-definition lens, so that the industrial camera can obtain accurate and high-definition images to ensure the normal use of the industrial camera, while avoiding the situation where the cleaning member directly contacts the lens of the industrial camera and may cause damage to the lens, thereby ensuring the service life of the industrial camera.

The transmission member has a connecting section rotatably connected to the shell, a transmission end transmission-connected to the driving member, and an action end acting on the cleaning member. When the driving member is working, the driving member drives the transmission end, and then causes the transmission end to swing around the connecting section, so that the action end also swings around the connecting section, thereby causing the action end to drive the cleaning member to move, so that the cleaning member cleans the high-definition lens. It can be understood that the reciprocating motion of the cleaning member in the first direction realizes the cleaning of the high-definition lens, thereby avoiding the existence of cleaning dead angles, thereby ensuring the camera quality of the industrial camera.

[0029] 3. The accommodating cavity in the present application is provided with a cleaning frame located on the side of the high-definition lens close to the sampling port, and guide grooves are provided on the opposite sides of the cleaning frame along the first direction, and the two ends of the cleaning member are respectively slidably connected to the guide grooves so that the guide grooves guide the movement of the cleaning member to increase the stability of the cleaning member, thereby ensuring the cleaning effect of the high-definition lens and ensuring the camera quality of the industrial camera.

[0061] Reference Figures 1 to 14 A dustproof and cleaning device for an industrial camera comprises a shell 1 having an accommodating cavity, a high-definition lens 2 arranged in the accommodating cavity, a cleaning member 3 arranged in the accommodating cavity and used for cleaning the high-definition lens 2, and a driving member 4 for driving the cleaning member 3 to move. One end of the shell 1 has a sampling port connected to the accommodating cavity, an industrial camera 10 is arranged inside the accommodating cavity and its lens faces the sampling port, and the high-definition lens 2 is located on the side of the lens of the industrial camera 10 facing the sampling port.

[0062] When the industrial camera 10 is working, the scene outside the shell 1 is collected by the industrial camera 10 through the sampling port and the high-definition lens 2; because the industrial camera 10 is arranged in the accommodating cavity, and a high-definition lens is arranged between the industrial camera 10 and the sampling port, the dust outside the shell 1 cannot pass through the high-definition lens 2 and adhere to the lens, so that the dust can only adhere to the high-definition lens 2; when cleaning the high-definition lens 2, start the driving member 4, and the driving member 4 drives the cleaning member 3 to make the cleaning member 3 and the high-definition lens 2 move relative to each other, and then make the cleaning member 3 clean the high-definition lens 2, so that the industrial camera 10 can obtain accurate and high-definition images to ensure the normal use of the industrial camera 10, and at the same time avoid the situation where the cleaning member 3 directly contacts the lens of the industrial camera 10 and may cause damage to the lens, thereby ensuring the service life of the industrial camera 10.

[0063] The present application does not specifically limit the structure of the cleaning member 3. Preferably, refer to Figure 4 and Figure 5 The cleaning member 3 includes a cleaning rod and a rubber sheet disposed on the cleaning rod, and the rubber sheet can contact the high-definition lens 2 to clean the high-definition lens 2. In other embodiments, the cleaning member 3 may also include a cleaning rod and a brush disposed on the cleaning rod, and the brush can contact the high-definition lens 2 to clean the high-definition lens 2.

[0064] The present application does not make any specific limitation on the structure of the high-definition lens 2 , which may be high-definition glass or a sheet structure made of resin material, as long as it can meet the requirements of the industrial camera 10 for taking pictures.

[0065] The present application does not specifically limit the relative movement mode between the cleaning member 3 and the high-definition lens 2. Preferably, refer to Figures 2 to 5 A transmission member 41 is provided in the accommodating cavity. The transmission member 41 has a connecting section rotatably connected to the shell 1, a transmission end transmission-connected to the driving member 4 and an action end acting on the cleaning member 3. When the driving member 4 is working, the transmission end rotates around the connecting section so that the action end drives the cleaning member 3 to move in the first direction.

[0066] That is to say, when cleaning the high-definition lens 2, the driving member 4 drives the transmission end, and then causes the transmission end to swing around the connecting section, so that the action end also swings around the connecting section, thereby causing the action end to drive the cleaning member 3 to move, so that the cleaning member 3 cleans the high-definition lens 2. It can be understood that the reciprocating motion of the cleaning member 3 in the first direction realizes the cleaning of the high-definition lens 2, thereby avoiding the existence of cleaning dead corners, thereby ensuring the camera quality of the industrial camera 10.

[0067] It should be noted that, when the sampling port is arranged vertically, the first direction may be a vertical direction or a horizontal direction and is not specifically limited here.

[0068] The present application does not specifically limit the structure of the driving member 4. Preferably, refer to Figures 2 to 5The driving member 4 is a cylinder, the piston rod of the cylinder is provided with a driving rod, the driving rod is arranged parallel to the rotation axis of the connecting section, the transmission end is provided with a strip groove, the driving rod is inserted into the strip groove, one end of the cleaning member 3 is provided with a connecting shaft parallel to the driving rod, and the action end is also provided with a strip groove, the connecting shaft is inserted into the strip groove of the action end, so that when the piston rod of the cylinder moves, the piston rod drives the driving rod to move, and the driving rod and the strip groove of the driving end slide relative to each other, so that the driving end swings around the connecting section under the action of the driving rod, and the action end swings around the connecting section, so that the connecting shaft and the strip groove at the action end slide relative to each other, thereby realizing the movement of the cleaning member 3 in the first direction. At the same time, compared with the motor, setting the driving member 4 as a cylinder can also simplify the control program of the driving member 4, so as to reduce the control cost of the driving member 4, increase the stability of the movement of the cleaning member 3, and avoid the transmission structure between the motor and the cleaning member from slipping, so as to ensure the driving efficiency of the driving member 4 to the cleaning member 3.

[0069] In other embodiments, the transmission member 41 may be omitted, and the piston rod of the cylinder may directly act on the cleaning member 3 to achieve the movement of the cleaning member 3 in the first direction.

[0070] In a preferred embodiment, referring to Figures 2 to 5 A cleaning frame 5 is provided in the accommodating cavity and is located on the side of the high-definition lens 2 close to the sampling port. Guide grooves 51 are provided on opposite sides of the cleaning frame 5 along the first direction. Both ends of the cleaning member 3 are slidably connected to the guide grooves 51 respectively.

[0071] When the cleaning member 3 moves under the action of the driving member 4, the cleaning member 3 and the guide groove 51 slide relative to each other, so that the guide groove 51 guides the movement of the cleaning member 3 to increase the stability of the cleaning member 3, thereby ensuring the cleaning effect of the high-definition lens 2 and ensuring the camera quality of the industrial camera 10.

[0072] Further, see Figure 4 and Figure 5 The guide groove 51 has a straight section 511 and a curved section 512 that curves in a direction away from the high-definition lens 2 , and a projection of the curved section 512 toward the high-definition lens 2 is located outside the high-definition lens 2 .

[0073] When cleaning of the high-definition lens 2 stops, the cleaning member 3 moves to the curved section 512, at which time the cleaning member 3 is separated from the high-definition lens 2. Since the curved section 512 is bent toward the high-definition lens 2 and the projection toward the high-definition lens 2 is located outside the high-definition lens 2, the cleaning member 3 and the high-definition lens 2 are avoided to prevent the cleaning member 3 from being within the shooting range of the industrial camera 10, so as to ensure the shooting quality of the industrial camera 10.

[0074] In other embodiments, the driving member 4 may also be configured to drive the cleaning member 3 to swing, that is, the cleaning member 3 and the high-definition lens 2 swing relative to each other, thereby cleaning the high-definition lens 2.

[0075] In a preferred embodiment, referring to Figure 1 A through opening 12 is provided on the side of the shell 1 corresponding to the high-definition lens 2 , and the high-definition lens 2 enters the accommodating cavity through the through opening 12 .

[0076] Due to the long-term friction between the cleaning member 3 and the high-definition lens 2, the high-definition lens 2 may be damaged. At this time, the high-definition lens 2 can be taken out through the opening 12 and then replaced to ensure the image quality of the industrial camera 10.

[0077] In a preferred embodiment, referring to 2, Figure 6 and Figure 7 A lens frame 21 is disposed outside the high-definition lens 2 , and a rubber pad 211 is disposed between the lens frame 21 and the high-definition lens 2 .

[0078] A lens frame 21 is provided on the outside of the high-definition lens 2, and a rubber pad 211 is provided between the high-definition lens 2 and the lens frame 21, so that the lens frame 21 and the rubber pad 211 can have a shock-absorbing effect on the high-definition lens 2, and then the lens frame 21 can protect the high-definition lens 2 to avoid damage to the high-definition lens 2 due to vibration of the shell 1, thereby further ensuring the camera quality of the industrial camera 10.

[0079] It should be noted that the above-mentioned “a lens frame 21 is provided on the outside of the high-definition lens 2 ” means that a lens frame 21 is provided on the peripheral side of the high-definition lens 2 , that is, it can be understood that the high-definition lens 1 is installed in the lens frame 21 .

[0080] In a preferred embodiment, referring to Figure 1 and Figure 6 A pull rod 212 is provided on the outside of the lens frame 21 so that the staff can replace the high-definition lens 2.

[0081] In a preferred embodiment, referring to Figure 6 , Figure 8 and Fig. 9 A support frame 6 is disposed in the accommodating cavity and is located on a side of the lens frame 21 close to the industrial camera 10 . The support frame 6 is provided with an elastic member 7 that acts on the lens frame 21 .

[0082] After the lens frame 21 with the high-definition lens 2 is installed in the shell 1, the elastic member 7 applies elastic force to the lens frame 21 to offset the gap between the lens frame 21 and the support frame 6, thereby avoiding the possible shaking of the lens frame 21 and further ensuring the camera quality of the industrial camera 10; at the same time, the elastic member 7 acts on the lens frame 21 to increase the connection stability between the lens frame 21 and the shell 1.

[0083] Further, see Fig. 9 The support frame 6 is provided with a receiving groove 61, the elastic member 7 includes a contact portion 71 provided at the notch of the receiving groove 61 and an elastic portion 72 provided inside the receiving groove 61 and acting on the contact portion 71, and the lens frame 21 is provided with a groove 213 corresponding to the contact portion 71.

[0084] When installing the lens frame 21 with the high-definition lens 2 installed, the lens frame 21 first contacts the contact portion 71, and then pressure is applied to the lens frame 21 so that the contact portion 71 compresses the elastic portion 72 under the action of the pressure of the lens frame 21, so that the contact portion 71 and the lens frame 21 form an avoidance. When the groove 213 on the lens frame 21 moves to the position of the contact portion 71, the contact portion 71 moves into the groove 213 under the action of the elastic portion 72, so that the contact portion 71 and the groove 213 are plugged into and matched to fix the lens frame 21, so as to increase the stability of the lens frame 21.

[0085] The present application does not specifically limit the structure of the elastic portion 72. Preferably, the elastic portion 72 is a spring to ensure that the elastic portion 72 can exert an elastic force on the contact portion 71, thereby ensuring the stability of the lens frame 21. In other embodiments, the elastic portion 72 can also be an elastic sheet, an elastic column, or other structures that can undergo elastic deformation.

[0086] The present application does not specifically limit the structure of the contact portion 71. Preferably, the contact portion 71 is a spherical structure to facilitate the installation of the lens frame 21 into the housing 1. In other embodiments, the contact portion 71 may also be a rod-shaped structure with a spherical surface at one end.

[0087] The present application does not specifically limit the installation method of the elastic portion 72 and the contact portion 71. Preferably, refer to Fig. 9, the receiving groove 61 is a through hole that penetrates the support frame 6, and the opening on the side where the contact portion 71 is located is smaller than the opening on the side where the elastic portion 72 is located, so that a part of the contact portion 71 extends out of the support frame 6 through the opening, and the support frame 6 is provided with a blocking sheet 62, and the blocking sheet 62 blocks the side with the larger opening of the receiving groove 61, that is, the contact portion 71 and the elastic portion 72 are both installed in the receiving groove 61 through the side with the larger opening of the receiving groove 61, so as to achieve the effect of facilitating the installation of the contact portion 71 and the elastic portion 72. In other embodiments, the receiving groove 61 has an opening, and the opening is arranged toward the lens frame 21, at which time, the end of the elastic portion 72 away from the contact portion 71 is fixedly connected to the groove wall of the receiving groove 61, and the contact portion 71 is fixedly connected to the elastic portion 72.

[0088] In a preferred embodiment, referring to Figure 2 , Fig.10 , Fig.11 and Fig.12 A blowing member 8 is provided in the accommodating cavity and is located on the side of the high-definition lens 2 facing the sampling port. The blowing member 8 has an air inlet 82 and an air outlet 83 connected with the air inlet 82 and facing the sampling port.

[0089] Better, refer to Figure 2 , Fig.10 , Fig.11 and Fig.12 The blowing member 8 is a frame-shaped structure, an air flow channel 81 is arranged inside the frame-shaped structure, and a guide surface is arranged on the inner side of the frame-shaped structure. The air outlet 83 is arranged on the guide surface and is connected with the air flow channel 81, so that the air outlet 83 faces the sampling port, and the air inlet 82 is connected with the air flow channel 81.

[0090] When the industrial camera 10 is working, the external air supply part is connected to the air inlet 82, so that the air enters the air flow channel 81 through the air inlet 82, and the air in the air flow channel 81 is discharged through the air outlet 83. Since the air outlet 83 is toward the sampling port, the air discharged through the air outlet 83 moves toward the sampling port, so that an airflow from the inside to the outside is formed inside the shell 1, and dust or particles outside the shell 1 are prevented from entering the shell 1, thereby preventing dust from adhering to the high-definition lens 2. At the same time, it can also prevent dust from affecting the camera quality of the industrial camera 10 at the sampling port.

[0091] In a preferred embodiment, referring to Figure 1 , Figure 2 , Fig.13 and Fig.14 A door body 9 capable of relative movement with the sampling port and a power member 91 for driving the door body 9 to move are provided at the sampling port, so that the door body 9 has an open state in which the sampling port is opened and a closed state in which the sampling port is closed.

[0092] When the industrial camera 10 stops working, the power part 91 drives the door body 9 to make the door body 9 and the sampling port move relative to each other, and then the door body 9 moves from an open state to a closed state to close the sampling port, thereby preventing dust or particles outside the shell 1 from entering the shell 1, so as to ensure the cleanliness of the inside of the shell 1, and further ensure the imaging quality of the industrial camera 10.

[0093] The present application does not specifically limit the relative movement mode between the door body 9 and the sampling port. Preferably, the door body 9 is hinged at the sampling port so that the door body 9 can open or close the sampling port by rotating, thereby increasing the sealing effect of the sampling port when the door body 9 is in the closed state. In other embodiments, the door body 9 can also be slidably connected to the sampling port so that the door body 9 can open or close the sampling port by sliding.

[0094] The present application does not specifically limit the structure of the power member 91. Preferably, refer to Fig.13 and Fig.14 The power part 91 is a cylinder arranged in the accommodating chamber, and a guide block 13 is arranged in the accommodating chamber. A linkage rod 911 is arranged on the piston rod of the cylinder, and the linkage rod 911 is penetrated through the guide block 13. An opening and closing rod 912 is hinged at one end of the linkage rod 911 away from the cylinder, and an end of the opening and closing rod 912 away from the linkage rod 911 is hinged to the door body 9, so that when the piston rod of the cylinder is retracted, the linkage rod 911 and the guide block 13 slide relative to each other and move in a direction away from the door body 9, thereby causing the opening and closing rod 912 to pull the door body 9, and the door body 9 and the shell 1 rotate relative to each other, so that the door body 9 moves toward a closed state; when the piston rod of the cylinder is extended, the linkage rod 911 moves in a direction close to the door body 9, thereby causing the opening and closing rod 912 to push the door body 9, and the door body 9 and the shell 1 rotate relative to each other, so that the door body 9 moves toward an open state. In other embodiments, the power member 91 may also be a motor, and the output shaft of the motor is coaxially arranged with the rotation axis of the door body 9 and fixedly connected to the door body 9 to realize opening or closing of the door body 9.

[0096] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0097] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
