Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and more particularly to a camera device for medical equipment, and medical equipment including the above-mentioned camera device. Background Technology

[0002] When medical equipment treats patients, it needs to be equipped with cameras to monitor them. Fixed cameras are limited by their installation location and are prone to blind spots. To increase the monitoring range of the cameras, pan-tilt units driven by two motors are often used to actively control the camera to rotate around two axes. Because these pan-tilt units have two motors, the control process is not only complex, but the manufacturing cost is also high. Utility Model Content

[0003] The purpose of this invention is to provide a camera device whose camera can rotate around two axes to adjust the control range. The control process is simple and the cost is lower.

[0004] Another objective of this invention is to provide a medical device whose camera can rotate around two axes to adjust the control range, with a simple control process and lower cost.

[0005] This invention provides a camera device, including a transmission assembly, a camera, a cylindrical cam, a drive component, and a motor. The transmission assembly includes a support component. The camera is used to acquire image information and is rotatably connected to the support component about a first axis. The cylindrical cam is rotatably sleeved on the outside of the support component, and the axis of the cylindrical cam is a second axis, which is perpendicular to the first axis. The drive component can rotate relative to the cylindrical cam under the drive of the camera, and the cylindrical cam can drive the drive component to move in a direction parallel to the second axis, thereby driving the camera to rotate about the first axis. The motor includes a fixed part and a rotating part. The fixed part can be fixed to a component of a medical device. The rotating part can rotate relative to the fixed part in two circumferential directions. The rotating part can be connected to and drive the camera through the transmission assembly to rotate about the second axis or an axis parallel to the second axis relative to the fixed part. The rotating part can also be connected to and drive one of the support component and the cylindrical cam to rotate relative to the other through the transmission assembly.

[0006] The camera device provided by this utility model includes only one motor. The motor can be connected to and drive the camera through a transmission assembly, rotating relative to the fixed part about a second axis or an axis parallel to the second axis. In addition, the rotating part can also be connected to and drive one of the support member and the cylindrical cam to rotate relative to the other through the transmission assembly. The cylindrical cam drives the camera to rotate about the first axis. The camera device provided by this utility model enables the camera to rotate about two mutually perpendicular axes to adjust the monitoring range using only one motor. The control process is simple and the cost is lower.

[0007] In another illustrative embodiment of the camera device, the camera device further includes a connecting rod. One end of the connecting rod is rotatably connected to the camera about an axis parallel to the first axis, and the other end of the connecting rod is rotatably connected to a driving component about an axis parallel to the first axis. This simple structure enables linkage between the driving component and the camera.

[0008] In another illustrative embodiment of the camera device, the cylindrical cam includes a cylindrical surface and a curved groove formed on the cylindrical surface. The drive member includes a limiting portion passing through the curved groove, and the limiting portion is located within the cylindrical cam to prevent the drive member from disengaging from the curved groove. This simple structure allows the drive member to be movably disposed on the cylindrical cam, and the cylindrical cam is capable of driving the drive member to move in two opposite directions.

[0009] In another illustrative embodiment of the camera device, the rotating part is connected to the support member, and the fixed part is connected to the cylindrical cam.

[0010] In another illustrative embodiment of the camera device, a rotating part is sleeved on the outside of the fixed part, the rotating part is connected to a cylindrical cam, and the rotation axis of the rotating part coincides with the second axis. The transmission assembly also includes a one-way rotating connector and a brake. The one-way rotating connector connects the cylindrical cam and the support member respectively, enabling the cylindrical cam to drive the support member to rotate in one circumferential direction and to rotate relative to the support member in another circumferential direction. The brake is connected to the fixed part and can generate an action to connect or release the fixed part and the support member. With the above structure, the horizontal and vertical angles of the camera can be adjusted separately, providing greater flexibility.

[0011] In another illustrative embodiment of the camera device, the camera device further includes a rotating base. The rotating base is connected to the rotating part and the cylindrical cam respectively. The rotating base has an inner cavity and two openings communicating with the inner cavity. A support member passes through one of the two openings, and a fixing part passes through the other opening. A one-way rotating connector and a braking member are located in the inner cavity. The rotating base can protect the one-way rotating connector and the braking member.

[0012] In another illustrative embodiment of the camera device, the one-way rotating connector is a one-way bearing.

[0013] In another illustrative embodiment of the camera device, the motor is a stepper motor. The camera device also includes several buttons and a controller. The controller is connected to the buttons and the motor, and can control the motor to drive the camera to a preset position corresponding to each button based on the action of the button. This allows the operator to directly adjust the camera to the preset position, making operation more convenient.

[0014] This utility model also provides a medical device, including the above-mentioned camera device.

[0015] In another illustrative embodiment of the medical device, the medical device further includes a bed base and uprights. The bed base is used to support the bed board. One end of the uprights is fixed to the bed base, and a fixing part is fixed to the other end of the uprights. Attached Figure Description

[0052] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0053] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0054] In this document, "first" and "second" do not indicate their importance or order, but are only used to distinguish them to facilitate the description of the document.

[0055] To keep the drawings simple, each drawing only schematically shows the parts related to this utility model, and they do not represent the actual structure of the product.

[0056] Figure 1 This is an exploded structural diagram illustrating one illustrative embodiment of the camera device. Figure 2 This is a cross-sectional structural diagram illustrating the camera device in its operational state. (Refer to...) Figure 1 and Figure 2 The camera device includes a transmission assembly 10, a camera 20, a cylindrical cam 30, a drive component 40, and a motor 50.

[0057] Reference Figure 1 and Figure 2 The transmission assembly 10 includes a support member 12. A camera 20 is used to acquire image information. The camera 20 is rotatably connected to the support member 12 about a first axis R1, allowing the support member 12 to support the camera 20 at any angle. A cylindrical cam 30 is rotatably sleeved on the outside of the support member 12. The axis of the cylindrical cam is a second axis R2, and the second axis R2 is perpendicular to the first axis R1. A drive member 40 can rotate relative to the cylindrical cam 30 under the drive of the camera 20. Simultaneously, the cylindrical cam 30 can drive the drive member 40 to move in a direction parallel to the second axis R2, thereby driving the camera 20 to rotate about the first axis R1.

[0058] Figure 3 This is a cross-sectional structural diagram illustrating another operating state of the camera device. (Refer to...) Figure 2 and Figure 3 In the illustrative embodiment, the camera device further includes a connecting rod 60. One end of the connecting rod 60 is rotatably connected to the camera 20 about an axis parallel to the first axis R1, and the other end of the connecting rod 60 is rotatably connected to the driving member 40 about an axis parallel to the first axis R1. With the help of the connecting rod 60, when the driving member 40 moves in a direction parallel to the second axis R2, the camera 20 can simultaneously rotate about the first axis R1, achieving linkage between the driving member 40 and the camera 20 with a simple structure. However, this is not a limitation. In other illustrative embodiments, the camera device may not include the connecting rod 60, and the linkage between the driving member 40 and the camera 20 may be achieved in other ways, such as by the driving member 40 directly abutting against the camera 20 to drive its rotation.

[0059] Reference Figure 2 and Figure 3The motor 50 includes a fixed part 52 and a rotating part 54. The fixed part 52 is a component that can be fixed to the medical device; in the illustrative embodiment, the fixed part 52 is fixed to the upright 94. The rotating part 54 is capable of rotating relative to the fixed part 52 in two circumferential directions. The rotating part 54 can be connected to and drive the camera 20 via the transmission assembly 10 to rotate relative to the fixed part 52 about a second axis R2 or an axis parallel to the second axis R2. The rotating part 54 can also be connected to and drive one of the support member 12 and the cylindrical cam 30 to rotate relative to the other via the transmission assembly 10.

[0060] Reference Figure 2 and Figure 3 In the illustrative embodiment, the rotating part 54 is connected to the support member 12, and the fixed part 52 is connected to the cylindrical cam 30. When the rotating part 54 rotates relative to the fixed part 52, the support member 12 and the driving camera 20 rotate relative to the upright 94 about the second axis R2 or an axis parallel to the second axis R2, thereby adjusting the horizontal angle of the camera 20. Simultaneously, because the support member 12 rotates relative to the cylindrical cam 30, the driving member 40 can drive the camera 20 to rotate about the first axis R1, thereby adjusting the pitch angle of the camera 20. The shape of the cylindrical cam 30 can be designed according to the actual usage scenario, so that when the camera 20 is adjusted to a specific horizontal angle, the camera 20 also simultaneously reaches a specific pitch angle. However, this is not a limitation; in other illustrative embodiments, the transmission assembly 10 may include other structures, and the rotating part 54 may drive the support member 12 and the cylindrical cam 30 in other ways.

[0061] The camera device provided by this utility model includes only one motor 50. The motor 50 can be connected to and drive the camera 20 through the transmission assembly 10 to rotate relative to the fixed part 52 about the second axis R2 or an axis parallel to the second axis R2. In addition, the rotating part 54 can also be connected to and drive one of the support member 12 and the cylindrical cam 30 to rotate relative to the other through the transmission assembly 10. The cylindrical cam 30 drives the camera 20 to rotate about the first axis R1. The camera device provided by this utility model enables the camera 20 to rotate about two mutually perpendicular axes to adjust the monitoring range using only one motor 50. The control process is simple and the cost is lower.

[0062] Reference Figures 1 to 3In the illustrative embodiment, the cylindrical cam 30 includes a cylindrical surface 31 and a curved groove 32 formed on the cylindrical surface 31. The drive member 40 includes a limiting portion 42, which passes through the curved groove 32 and is located within the cylindrical cam 30. In conjunction with the camera 20 and the connecting rod 60, the limiting portion 42 prevents the drive member 40 from disengaging from the curved groove 32. This simple structure allows the drive member 40 to be movably disposed on the cylindrical cam 30, and the cylindrical cam 30 can drive the drive member 40 to move in two opposite directions.

[0063] Figure 4 This is a schematic diagram illustrating a partial structure of the camera device. (Refer to...) Figure 4 The motor 50 is a stepper motor. The camera device also includes several buttons 82 and a controller 84. The controller 84 is connected to the buttons 82 and the motor 50. The controller 84 can control the motor 50 to drive the camera 20 to a preset position corresponding to each button 82 based on the action of each button 82. In this way, the operator can directly adjust the camera 20 to the preset position, making operation more convenient.

[0064] Figure 5 This is a schematic diagram illustrating another embodiment of the camera device. Figure 6 This is a cross-sectional structural diagram illustrating the working state of another illustrative embodiment of the camera device. (Refer to...) Figure 5 and Figure 6 , and Figures 1 to 3 The similarities and similarities of the illustrative embodiments shown will not be repeated here. The difference is that the rotating part 54 is sleeved on the outside of the fixed part 52, the rotating part 54 is connected to the cylindrical cam 30, and the rotation axis of the rotating part 54 coincides with the second axis R2. The transmission assembly 10 also includes a one-way rotating connector 14 and a brake 16.

[0065] Figure 7 and 8 These are cross-sectional structural diagrams illustrating different operating states of the camera device. (Refer to...) Figures 6 to 8 The one-way rotating connector 14 is a one-way bearing, which connects the cylindrical cam 30 and the support member 12. The one-way rotating connector 14 enables the cylindrical cam 30 to drive the support member 12 to rotate in one circumferential direction and to rotate relative to the support member 12 in another circumferential direction. The brake member 16 connects to the fixed part 52 and can actuate to connect the fixed part 52 and the support member 12, causing them to rotate synchronously through friction or thrust. Alternatively, the brake member 16 can actuate to release the fixed part 52 and the support member 12, allowing them to move relative to each other.

[0066] Reference Figure 6 and Figure 7 When the brake 16 actuates to release the fixing part 52 and the support part 12, the rotating part 54 can drive the cylindrical cam 30, the support part 12, and the camera 20 to rotate relative to the upright 94 around the second axis R2 in a clockwise direction, thereby adjusting the horizontal angle of the camera 20. (Refer to...) Figure 6 and Figure 8 When the brake 16 actuates to connect the fixing part 52 and the support part 12, the support part 12 and the camera 20 are fixed. The rotating part 54 can drive the cylindrical cam 30 to rotate relative to the support part 12 in a counterclockwise direction, so that the driving part 40 can drive the camera 20 to rotate around the first axis R1, thereby adjusting the pitch angle of the camera 20. With the above structure, the horizontal angle and pitch angle of the camera 20 can be adjusted separately, providing greater flexibility.

[0067] Reference Figure 5 and Figure 6 In the illustrative embodiment, the camera device also includes a rotating base 70. The rotating base 70 connects the rotating part 54 and the cylindrical cam 30. The rotating base 70 has an inner cavity 72 and two openings 74 communicating with the inner cavity 72. The support member 12 passes through one of the two openings 74, and the fixing part 52 passes through the other opening 74. The one-way rotating connector 14 and the brake member 16 are located in the inner cavity 72. The rotating base 70 protects the one-way rotating connector 14 and the brake member 16.

[0068] This utility model also provides a medical device, including the above-mentioned camera device. Figure 9 This is a schematic diagram illustrating one embodiment of a medical device. (Refer to...) Figure 9 In this illustrative embodiment, the medical device is a magnetic resonance imaging (MRI) device, which also includes a bed base 92, a bed board 93, a support rod 94, and a frame 96. The bed base 92 is disposed on one side of the frame 96 and is used to support the bed board 93. One end of the support rod 94 is fixed to the bed base 92, and the fixing part 52 is fixed to the other end of the support rod 94. However, this is not a limitation. In other illustrative embodiments, the medical device may be other types of devices, and may only include the bed base 92 and the support rod 94.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
