Description

Technical Field

[0001] This specification relates to the field of electromechanical control technology, and in particular to a control device. Background Technology

[0002] Rollers are a common control component in control equipment. Users can control mechanical equipment (e.g., controlling the rotation of a C-arm X-ray machine) or software (e.g., controlling the page turning of a webpage or document) by sliding the rollers forward or backward.

[0003] Existing roller arrangements often suffer from structural problems, which can lead to abnormal roller rotation during daily use due to various reasons. This reduces the reliability of control equipment with rollers installed. In the medical field, the use of medical equipment is often related to the health and even life of patients, so medical equipment often has high requirements for the reliability of control equipment.

[0004] Therefore, how to improve the reliability of control equipment with roller components is an urgent problem to be solved. Summary of the Invention

[0005] This specification provides a control device to partially solve the aforementioned problems existing in the prior art.

[0006] The following technical solution is adopted in this specification:

[0007] This specification provides a control device, which includes: a panel body 1, a baffle 2, a support component 3, an annular roller 4, and an encoder 5. The panel body 1 is provided with an opening slot, and the annular roller 4 passes through the opening slot and partially passes through the panel body 1. The baffle 2 passes through the annular roller 4 and is fastened to the panel body 1. The support component 3 is provided with a horizontal crossbar 6 passing through the annular roller 4 and at least three fixed gears 7. The fixed gears 7 mesh with the gear teeth on the inner side of the annular roller 4.

[0008] When the annular roller 4 rotates, it drives the encoder 5 to generate an electrical signal;

[0015] The clamping component 9 is used to clamp the damping adjustment gear 8. By controlling the position of the clamping component 9 in the horizontal bar 6, the pressure between the damping adjustment gear 8 and the support component 3 is adjusted to adjust the damping magnitude when the damping adjustment gear 8 rotates.

[0016] Optionally, the clamping component 9 includes: an anti-loosening nut;

[0021] The fixing component 10 is used to fix the position between the supporting component 3 and the panel body 1.

[0022] Optionally, the encoder 5 is provided with a gear 11;

[0023] When the annular roller 4 rotates, it drives the gear 11, causing the encoder 5 to generate an electrical signal.

[0036] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of this specification will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of them. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0037] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0038] A roller device is a commonly used control device. Users can move the roller forward or backward, causing an encoder within the device to generate electrical signals based on the roller's rotation. This allows equipment equipped with the roller device to identify the direction and speed of the roller's rotation based on these signals, and then control the device accordingly. For example, a control device equipped with this roller device can adjust the position of a C-arm X-ray machine based on the received electrical signals. Another example is a control device equipped with this roller device that can control specified functions in the software, such as turning pages in a document or webpage, based on the received electrical signals.

[0039] In existing technologies, the design of scroll wheels often requires a rectangular opening on the surface of the control device (e.g., control equipment, mouse, etc.) so that the upper part of the scroll wheel can be exposed through this opening for the user to flick. However, in order to avoid the scrolling rotation being affected by the opening, a large gap is often required between the opening and the scroll wheel. In practical applications, these gaps may allow foreign objects to fall in, causing the scroll wheel to get stuck, thus affecting the scrolling rotation.

[0040] Based on this, this specification provides a control device comprising: a panel body 1, a baffle 2, a support component 3, an annular roller 4, and an encoder 5. The panel body 1 has an opening slot, through which the annular roller 4 partially passes. The baffle 2 passes through the annular roller 4 and engages with the panel body 1. The support component 3 has a horizontal crossbar 6 passing through the annular roller 4 and at least three fixed gears 7. The fixed gears 7 mesh with the teeth on the inner side of the annular roller 4. When the annular roller 4 rotates, it drives the encoder 5 to generate an electrical signal. The encoder 5 sends the electrical signal to the control device, enabling the control device to control the position and posture of a specified device based on the electrical signal. Figure 1 As shown.

[0041] Figure 1 This is a schematic diagram of the structure of a control device provided in this specification.

[0042] Combination Figure 1 As can be seen, there is an opening groove in the panel body 1, through which the annular roller 4 can partially pass through the panel body 1 for the user to rotate.

[0043] The middle area of ​​the baffle 2 is raised (the raised middle area is square), and the two side areas are lower than the middle area. The baffle passes through the annular roller 4 and is fastened to the panel body 1 so that the raised middle area of ​​the baffle 2 can seal the opening between the annular roller 4 and the panel body 1, thereby avoiding the gap between the annular roller 4 and the panel body 1. The lower areas on both sides of the baffle 2 are fastened to the panel body 1 from below to fix the baffle 2 to the panel body 1.

[0044] The support member 3 is provided with a horizontal crossbar 6 passing through the annular roller 4 and at least three fixed gears 7. The fixed gears 7 mesh with the teeth on the inner side of the annular roller 4. The horizontal crossbar 6 of the support member 3 may be provided with teeth, and the teeth mesh with the teeth of the annular roller 4. Thus, when the annular roller rotates, the horizontal crossbar 6 can be driven to rotate. The horizontal crossbar 6 may also be provided with a bracket, which can be fixed on the horizontal crossbar 6. The fixed gears 7 can be fixed on the bracket so that the fixed gears on the bracket mesh with the teeth of the annular roller 4 and provide support for the annular roller 4.

[0045] Furthermore, if the axis of encoder 5 and the axis of horizontal bar 6 are on the same horizontal line, the height of encoder 5 itself may exceed the height between horizontal bar and panel body 1, leading to difficulties in fixing it. Therefore, a gear 11 can be provided at one end of encoder 5 near support member 3. This gear 11 can pass through a pre-drilled hole on the bracket provided on support member and mesh with annular roller 4. Figure 1 The encoder shown can further drive the gear 11 to rotate when the annular roller 4 rotates, thereby driving the encoder 5 to generate an electrical signal.

[0046] As can be seen from the above, by setting a gear 11 at one end of the encoder 5, the axis of the encoder 5 and the horizontal crossbar 6 of the support component 3 can be not on the same horizontal line (that is, the encoder 5 can be set diagonally below the horizontal crossbar of the support component 3). This avoids the problem of inconvenience in fixing caused by the height of the encoder 5 exceeding the height between the horizontal crossbar 6 and the panel body 1. As a result, the space requirement for arranging the encoder 5 is lower, thereby improving the utilization rate of the internal space of the control equipment.

[0047] In addition, the ratio of the number of rotations of the gear 11 at one end of the encoder 5 to the number of rotations of the annular roller 4 can be adjusted by adjusting the size of the gear 11 at one end of the encoder 5. For example, the gear 11 at one end of the encoder 5 rotates three times for the annular roller 4 to rotate once, or the gear 11 at one end of the encoder 5 to rotate four times for the annular roller 4 to rotate once.

[0048] The inner side of the annular roller 4 is provided with teeth, and the rotation of the annular roller 4 can be transmitted to the encoder 5 through the inner teeth.

[0049] In addition, to meet the personalized needs of users, the control device is also equipped with a damping adjustment gear 8, which meshes with the fixed gear in the support component 3 (the damping adjustment gear 8 can be externally connected to each of the fixed gears). Thus, the damping of the rotation of the annular roller 4 can be adjusted according to the personalized needs of users through the damping adjustment gear 8. The damping adjustment gear 8 has a circular hole in its center. The support component 3 can provide support for the damping adjustment gear 8 by passing a horizontal bar through the circular hole of the damping adjustment gear 8, and allow the damping adjustment gear 8 to rotate around the horizontal bar as the axis. Furthermore, the support component 3 can transmit the damping magnitude of the rotation of the damping adjustment gear 8 to the annular roller 4 through the fixed gear set on the bracket.

[0050] Specifically, the control device is also equipped with a clamping component 9, which is used to clamp the damping adjustment gear 8. By controlling the position of the clamping component 9 in the horizontal bar 6, the pressure between the damping adjustment gear 8 and the support component 3 is adjusted to adjust the damping magnitude when the damping adjustment gear 8 rotates.

[0051] The clamping component 9 can be a combination of a locking nut and an elastic component. The locking nut and the elastic component can be fixed on the horizontal bar 6 of the support component 3. By adjusting the tightness of the locking nut, the compression of the elastic component can be adjusted, thereby adjusting the pressure of the elastic component on the damping adjustment gear 8 and the support component 3, and thus adjusting the damping magnitude when the damping adjustment gear 8 rotates. The elastic component can be a part such as a disc spring or a spring.

[0052] Furthermore, in order to fix the support member 3 to the panel body 1, a fixing member 10 is provided between the support member 3 and the panel body 1. The fixing member 10 is fixedly installed at the lower end of the panel body 1, and the horizontal crossbar 6 passes through the hole in the fixing member 10. The fixing member 10 is used to fix the position between the support member 3 and the panel body 1.

[0053] In the above description, the baffle 2 can seal the opening between the annular roller 4 and the panel body 1, such as... Figure 2 As shown.

[0054] Figure 2 This is a schematic diagram illustrating the method of sealing the opening between the annular roller and the panel body using a baffle, as provided in this specification.

[0055] exist Figure 2In the diagram, the light gray area represents the panel body 1, the white area represents the region where the annular roller 4 passes through the panel body 1 (i.e., the cross-section of the annular roller 4 on the panel body 1), and the dark gray area represents the region blocked by the baffle 2. Figure 2 As can be seen, the baffle 2 can seal the opening between the annular roller 4 and the panel body 1, thereby reducing the gap between the annular roller 4 and the panel body 1, thus preventing foreign objects from falling into the annular roller 4 during daily use and causing the annular roller 4 to get stuck.

[0056] To provide a detailed description of the portion of the annular roller 4 that passes through the panel body 1, this specification also includes a schematic diagram of the upper surface of the panel body 1, as shown below. Figure 3 As shown.

[0057] Figure 3 This is a left view of the upper surface of the panel body provided in this specification.

[0058] from Figure 3 As can be seen, the portion of the annular roller 4 passing through the upper part of the panel body 1 forms an "arch bridge shape". This "arch bridge shape" can reduce the actual opening area required by the panel body 1, thereby reducing the gap between the annular roller 4 and the panel body 1, and thus ensuring the reliability of the control device.

[0059] To provide a detailed description of the control equipment described in this manual, a schematic diagram of the control equipment is also provided, such as... Figure 4A , Figure 4B As shown.

[0060] Figure 4A This is a first overall schematic diagram of the control device provided in this specification. Figure 4B This is a second overall schematic diagram of the control device provided in this specification.

[0061] pass Figure 4A and Figure 4B As can be seen, the fixing component 10 can fix the support component 3 below the panel, so that the support component 3 can provide support for the damping adjustment gear 8, the clamping component 9, the ring roller 4, and the encoder 5. The damping adjustment gear 8 meshes with each fixed gear 7, and the ring roller 4 can mesh with each fixed gear 7 through its inner teeth, so that the damping magnitude of the damping adjustment gear 8 can be transmitted to the ring roller 4 through the fixed gear 7. The clamping component 9 can be fixed on the horizontal crossbar of the support component 3 to clamp the damping adjustment gear 8.

[0062] Additionally, it should be noted that the shape of the raised area in the middle of the baffle 2 can be varied, such as square, arc-shaped, etc. Specifically, when the raised area in the middle of the baffle 2 is arc-shaped, such as... Figure 5 As shown.

[0063] Figure 5 This is a schematic diagram of a baffle provided in this specification.

[0064] from Figure 5 As can be seen, the baffle 2 can be made into an arc shape in the middle protrusion area so as to block the opening between the annular roller 4 and the panel body 1 through the arc-shaped protrusion area.

[0065] To provide a detailed explanation of the position of the arc-shaped baffle 2 in the control device, as described above, a schematic diagram of the control device using the arc-shaped baffle is provided, as follows: Figure 6 As shown.

[0066] Figure 6 This is a schematic diagram of the control device using an arc-shaped baffle provided in this specification.

[0067] from Figure 6 As can be seen, the baffle 2 can seal the opening between the annular roller 4 and the panel body 1 through the central arc-shaped protrusion area, thereby preventing the gap between the annular roller 4 and the panel body 1.

[0068] Furthermore, the raised area in the middle of the baffle can also be set as an indicator light, which can indicate different working states of the control device (e.g., normal operation, abnormal operation, etc.) by using different colors of the indicator lights set in the baffle.

[0069] The support component 3 consists of a horizontal crossbar and at least three fixed gears 7, wherein each fixed gear on the support component 3 meshes with the teeth on the inner side of the annular roller 4. A circular hole is provided below the bracket, through which the gear on the encoder 5 can pass and mesh with the teeth on the inner side of the annular roller 4. The support component 3 can provide support for the annular roller 4 through the fixed gears provided on the bracket.

[0070] As can be seen from the above, the hollow annular roller 4 design allows the gap between the annular roller 4 and the panel body 1 to be filled by the baffle 2, thereby reducing the gap between the annular roller 4 and the panel body 1 and reducing the risk of the annular roller 4 getting stuck due to foreign objects. Furthermore, since the axis of the encoder 5 and the axis of the support component 3 can be located on different horizontal lines, the arrangement of the encoder 5 is more flexible. In addition, the damping adjustment gear 8 can adjust the damping magnitude when the annular roller 4 rotates, which not only enhances the reliability of the control device but also meets the personalized needs of users and improves the user experience.
