Description

Technical Field

[0001] This utility model relates to the field of mobile equipment technology, and in particular to a drive steering device for medical imaging equipment. Background Technology

[0002] In the medical field, medical imaging equipment plays a vital role. With the continuous advancement of medical technology, higher demands are placed on the performance and ease of use of medical imaging equipment. Medical imaging equipment is used to perform various imaging examinations on patients, which help doctors accurately diagnose conditions and provide crucial information for subsequent treatment. This type of equipment often needs to be moved between different departments or examination areas within a hospital; therefore, the mobility design of the equipment becomes a key factor affecting its overall performance.

[0003] Existing motion control systems for equipment generally employ a design where each of the two drive wheels is driven by an independent motor. This structure achieves basic motion control by precisely adjusting the speed difference between the two wheels. Specifically, when the two motors maintain synchronous speeds, the device moves stably along a straight trajectory; while when one motor's speed is higher than the other, the device will rotate around the lower-speed drive wheel as its center, forming an arc-shaped turning trajectory.

[0004] While the aforementioned technologies can achieve some trajectory control, it is limited, primarily confined to linear and circular motion. In actual clinical examination scenarios, equipment may need to move along complex curves, polygons, or other trajectories to adapt to different examination positions and angles. The aforementioned moving devices struggle to meet the demands of such complex trajectories, significantly restricting the application of medical imaging equipment in complex environments. Utility Model Content

[0005] To improve the flexibility of device use, this application provides a drive steering device for medical imaging equipment.

[0006] This application provides a drive steering device for medical imaging equipment, which adopts the following technical solution: A drive steering device for medical imaging equipment includes a main body, a fixed plate at the lower end of the main body, the fixed plate being detachably connected to the main body, two connecting blocks at the lower end of the fixed plate being rotatably connected to the fixed plate, the two connecting blocks being symmetrically distributed along the axis of the fixed plate, a drive wheel at the lower end of the connecting blocks being rotatably connected to the connecting blocks, each drive wheel having an independently rotating component that drives the drive wheel to rotate, a gear set at the lower end of the fixed plate, couplings fixed on both sides of the gear set being rotatably connected to the fixed plate, a first gear fixed at the upper end of the connecting blocks, a second gear fixed at the end of the coupling away from the gear set, the first gear meshing with the second gear, a rotary motor for driving the gear set to rotate fixed at the lower end of the fixed plate, and two auxiliary wheels at the lower end of the fixed plate for balancing the main body of the equipment.

[0007] By adopting the above technical solution, each drive wheel is equipped with an independently driven rotating component. By controlling the speed and direction of the two drive wheels separately, the equipment can achieve various complex movement modes such as linear forward and backward movement, as well as differential steering. During medical imaging examinations, the position and angle of the equipment can be flexibly adjusted. The two auxiliary wheels at the lower end of the fixed plate play a role in balancing the main body of the equipment, reducing the risk of tilting or tipping due to instability. The rotating motor drives the gear set to rotate, and the power is transmitted to gear two through the coupling. Then, gear one drives the connecting block to rotate, enabling the two drive wheels to turn simultaneously. This allows the device to move in multiple directions and improves the flexibility of its use.

[0008] Optionally, the gear set includes a driving bevel gear and two driven bevel gears. The driving bevel gear is fixed coaxially with the output shaft of the rotating motor. The two driven bevel gears are distributed symmetrically to the driving bevel gear. The driven bevel gears mesh with the driving bevel gears. Each driven bevel gear corresponds to a coupling, and the driven bevel gear is fixedly connected to its corresponding coupling.

[0009] By adopting the above technical solution, the two driven bevel gears are symmetrically distributed with respect to the driving bevel gear. This symmetrical layout allows the two driven bevel gears to rotate simultaneously and at the same speed when receiving power from the driving bevel gear. After the power is transmitted to the drive wheels through the coupling, the two drive wheels can achieve synchronous steering action, thereby ensuring the stability of the device during the steering process.

[0010] Optionally, the rotating component includes a coil and a magnet, with a shaft fixed to one side of the drive wheel, the shaft passing through the drive wheel, the coil wound around the outer surface of the shaft, and the magnet fixed inside the drive wheel.

[0011] By adopting the above technical solution, the coil is wound around the outer surface of the shaft, and the magnet is fixed inside the drive wheel. When the coil is energized, according to the principle of electromagnetic induction, the energized coil will experience an Ampere force in the magnetic field generated by the magnet. This electromagnetic drive method can directly convert electrical energy into mechanical energy, providing strong power to the drive wheel to make it roll, thereby driving the device to move.

[0012] Optionally, a gear three is fixed on one side of the drive wheel, and a slide plate is provided inside the connecting block. The slide plate is slidably connected to the connecting block in the vertical direction. A gear four corresponding to gear three is fixed on one side of the slide plate. When gear three and gear four mesh, the drive wheel remains stationary. A brake is fixed on one side of the slide plate, and the output shaft of the brake is coaxially fixed with gear four.

[0013] By adopting the above technical solution, when the drive wheel needs to stop rotating, the slide plate slides, allowing gear one and gear two to mesh, immediately restricting the rotation of the drive wheel. Simultaneously, the brake output shaft is coaxially fixed with gear two, allowing the brake to quickly apply braking force, which is then transmitted to the drive wheel via gear two, achieving instant braking and ensuring the equipment can stop accurately within a short time.

[0014] Optionally, two elastic elements are provided between the slide plate and the inner wall of the connecting block. The two elastic elements are symmetrically distributed along the slide plate. A fixing bolt is fixed at the end of the elastic element away from the slide plate. The fixing bolt is threadedly connected to the connecting block. In its natural state, the elastic element drives gear three and gear four to separate.

[0015] By adopting the above technical solution, when braking, rotating the fixing bolt causes the elastic element to press the slide plate, which then descends and engages gear four with gear three. When unlocking, rotating the fixing bolt causes gear three with gear four to separate under the elastic force of the elastic element, allowing the drive wheel to rotate, thus improving the convenience of using the device.

[0016] Optionally, a sensing plate is fixedly provided at the upper end of the connecting block, and a limit sensor and a zero-point sensor corresponding to the sensing plate are fixedly provided at the lower end of the fixing plate. A sensing groove corresponding to the zero-point sensor is opened on the sensing plate. The sensing groove is located in the middle position of the sensing plate. When the drive wheel is exactly at the middle angle, the light emitted by the zero-point sensor can pass through the sensing groove.

[0017] By adopting the above technical solution, when the drive wheel is exactly at the middle angle, the light emitted by the zero-point sensor can pass through the sensing slot, and the device detects that the drive wheel is in the middle position. When the drive wheel rotates to the left position, the light emitted by the limit sensor of the right drive wheel can pass through the sensing slot, and the device detects that the drive wheel is in the left position. When the drive wheel rotates to the right position, the light emitted by the limit sensor of the left drive wheel can pass through the sensing slot, and the device detects that the drive wheel is in the right position, thus reducing the probability of oversteering.

[0018] Optionally, a handle is fixed to the upper end of the main body of the device, and a control component is provided on the upper surface of the handle. The control component is used to control the operation of the device.

[0019] By adopting the above technical solution, the handle is located at the upper end of the equipment body, a position that is usually natural and convenient for operators to hold the equipment. Operators can easily grip the handle without excessive bending over or stretching their arms, reducing fatigue during operation. Integrating the control components into the upper surface of the handle allows operators to conveniently perform various operations on the equipment while holding the handle, eliminating the need to search for control buttons on other parts of the equipment, thus improving operational convenience and efficiency.

[0020] Optionally, the connecting block has a wire hole, and a cable tie is fixed to the upper end of the connecting block to secure the cable used for connection.

[0021] By adopting the above technical solution, the cable guide hole provides a fixed channel for the cable, allowing it to pass through the connecting block along a predetermined path, reducing the likelihood of cables scattering or tangling. Cable ties further bind the cables passing through the cable guide hole together, making the cable arrangement more neat and orderly.

[0022] In summary, this application includes at least one of the following beneficial technical effects of the device: 1. The rotating motor drives the gear set to rotate, and the power is transmitted to the second gear through the coupling. Then, the first gear drives the connecting block to rotate, so that the two drive wheels can turn at the same time, enabling the device to move in multiple directions and improving the flexibility of the device. 2. When unlocking, rotate the fixing bolt, and under the action of the elastic force of the elastic element, gear three and gear four will separate. At this time, the drive wheel can rotate, which improves the convenience of using the unified device. 3. When the drive wheel is at the center angle, the light emitted by the zero-point sensor can pass through the sensing slot, and the device detects that the drive wheel is in the center position. When the drive wheel rotates to the left position, the light emitted by the limit sensor of the right drive wheel can pass through the sensing slot, and the device detects that the drive wheel is in the left position. When the drive wheel rotates to the right position, the light emitted by the limit sensor of the left drive wheel can pass through the sensing slot, and the device detects that the drive wheel is in the right position, thus reducing the probability of oversteering.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a drive steering device for medical imaging equipment. Example

[0032] Reference Figure 1 and Figure 2 A steering device for medical imaging equipment includes a main body 1, a fixed plate 2 at the lower end of the main body 1, the fixed plate 2 being detachably connected to the main body 1 for easy replacement of workpieces connected to the fixed plate 2, a rotating motor 3 at the lower end of the fixed plate 2, and a driving bevel gear 31 at the lower end of the fixed plate 2. The driving bevel gear 31 is coaxially fixed with the output shaft of the rotating motor 3. When the equipment needs to be turned, the rotating motor 3 starts and drives the driving bevel gear 31 to rotate. Two driven bevel gears 32 are provided at the lower end of the fixed plate 2. The driven bevel gears 32 are rotatably connected to a connecting plate. The two driven bevel gears 32 are symmetrically distributed with respect to the driving bevel gear 31. The driven bevel gears 32 mesh with the driving bevel gears 31. The rotation of the driving bevel gear 31 drives the two driven bevel gears 32 to rotate.

[0033] Reference Figure 2 and Figure 3A coupling 33 is fixed on the side of the driven bevel gear 32 away from the driving bevel gear 31. A second gear 35 is fixed on the side of the coupling 33 away from the driven bevel gear 32. The rotation of the driven bevel gear 32 drives the connected second gear 35 to rotate through the coupling 33. A connecting block 4 corresponding to the second gear 35 is provided at the lower end of the fixed plate 2. The connecting block 4 is rotatably connected to the fixed plate 2. A first gear 34 is fixed at the upper end of the connecting block 4. The first gear 34 meshes with the second gear 35. The rotation of the second gear 35 drives the connecting block 4 to rotate through the first gear 34. A drive wheel 41 is provided at the lower end of the connecting block 4. The drive wheel 41 is rotatably connected to the connecting block 4. The rotation of the connecting block 4 enables the two drive wheels 41 to turn simultaneously, thereby adjusting the movement direction of the equipment and improving the flexibility of the equipment.

[0034] Reference Figure 3 The drive wheel 41 contains a rotating component, which includes a coil 411 and a magnet 412. A rotating shaft is fixed to one side of the drive wheel 41, passing through the drive wheel 41. The coil 411 is wound around the outer surface of the rotating shaft, and the magnet 412 is fixed inside the drive wheel 41. When the coil 411 is energized, according to the principle of electromagnetic induction, the energized coil 411 will experience an Ampere force in the magnetic field generated by the magnet 412. This electromagnetic drive method can directly convert electrical energy into mechanical energy, providing strong power to the drive wheel 41 to make it roll, thereby driving the device to move. At the same time, each drive wheel 41 is individually controlled by the rotating component, which facilitates the realization of various complex movement modes such as linear forward and backward movement, as well as differential steering. The position and angle of the equipment can be flexibly adjusted, improving the flexibility of the device's use.

[0035] Reference Figure 1 The lower end of the fixed plate 2 is provided with two auxiliary wheels 21. The auxiliary wheels 21 are rotatably connected to the fixed plate 2, and the two auxiliary wheels 21 are symmetrically distributed along the fixed plate 2. During the movement of the equipment, the auxiliary wheels 21 can share part of the weight, maintain the balance of the equipment, reduce the tilting or overturning of the equipment due to the unstable center of gravity, and improve the stability of the device.

[0036] Reference Figure 2 and Figure 3 The coupling 33 is designed to be detachable. When it is necessary to adjust the initial angle of the two drive wheels 41, the coupling 33 is twisted. At this time, the steering angle of the drive wheel 41 can be adjusted individually. After the adjustment is completed, the coupling 33 is locked. At this time, the rotating motor 3 drives the two drive wheels 41 to adjust their angles simultaneously.

[0037] Reference Figure 4 and Figure 5A sensing plate 46 is fixedly mounted on the upper end of the connecting block 4, and a limit sensor 461 and a zero-point sensor 462 corresponding to the sensing plate 46 are fixedly mounted on the lower end of the fixing plate 2. A sensing groove 463 corresponding to the zero-point sensor 462 is opened on the sensing plate 46. The sensing groove 463 is located in the middle position of the sensing plate 46. When the drive wheel 41 is exactly at the middle angle, the light emitted by the zero-point sensor 462 can pass through the sensing groove 463, and the device detects that the drive wheel 41 is in the middle position. When the drive wheel 41 rotates to the left position, the light emitted by the limit sensor 461 of the right drive wheel 41 can pass through the sensing groove 463, and the device detects that the drive wheel 41 is in the left position. When the drive wheel 41 rotates to the right position, the light emitted by the limit sensor 461 of the left drive wheel 41 can pass through the sensing groove 463, and the device detects that the drive wheel 41 is in the right position, thus reducing the probability of over-steering.

[0038] Reference Figure 5 and Figure 6 A gear 3 42 is fixedly mounted on one side of the drive wheel 41. A slide plate 45 is provided inside the connecting block 4. The slide plate 45 is slidably connected to the connecting block 4 in a vertical direction. A gear 43 corresponding to the gear 3 42 is fixedly mounted on one side of the slide plate 45. A brake 44 is fixedly mounted on one side of the slide plate 45. The output shaft of the brake 44 is coaxially fixed with the gear 43. When the drive wheel 41 needs to stop rotating, the slide plate 45 slides, allowing the gear 3 42 to mesh with the gear 43. The brake 44 can quickly apply braking force, which is transmitted to the drive wheel 41 through the gear 2 35, realizing instant automatic braking and ensuring that the equipment can stop accurately in a short time, thus improving the safety of equipment use.

[0039] Reference Figure 6 Two elastic elements 451 are provided between the slide plate 45 and the inner wall of the connecting block 4. The two elastic elements 451 are symmetrically distributed along the slide plate 45. A fixing bolt 452 is provided at the end of the elastic element 451 away from the slide plate 45. The fixing bolt 452 is threadedly connected to the connecting block 4. When the automatic braking function fails to brake and unlock, the fixing bolt 452 is rotated, and the elastic element 451 presses the slide plate 45. The slide plate 45 descends, causing gear 43 to mesh with gear 42, thus achieving manual braking. When unlocking is required, the fixing bolt 452 is rotated, and the fixing bolt 452 no longer presses the elastic element 451. Under the action of the elastic force of the elastic element 451, gear 42 separates from gear 43. At this time, the drive wheel 41 can rotate, improving the convenience of the device. The aforementioned elastic element 451 can be a spring.

[0040] Reference Figure 1A handle 11 is fixedly provided at the upper end of the main body 1 of the equipment. The handle 11 is located at the upper end of the main body 1 of the equipment. This position is usually a more natural and convenient part for the operator to hold the equipment. The operator can easily hold the handle 11 without bending over or stretching the arm excessively, which reduces fatigue during operation. The upper surface of the handle 11 is provided with control components, which allows the operator to conveniently perform various operations on the equipment while holding the handle 11, without having to look for control buttons in other parts of the equipment, thus improving the convenience and efficiency of operation.

[0041] Reference Figure 3 and Figure 5 The connecting block 4 has a cable passage hole 47, which provides a fixed channel for the cable connected to the drive wheel 41, allowing the cable to pass through the connecting block 4 along a predetermined path, reducing the chance of the cable falling out or getting tangled. The upper end of the connecting block 4 is fixed with a cable tie 48, which binds the cable passing through the cable passage hole 47 together. When the equipment is subjected to external force or the parts move, the cable may be subjected to tensile force. The cable tie 48 can fix the cable to the connecting block 4, so that the cable has a fixed support point when subjected to external force.

[0042] The implementation principle of a medical imaging equipment drive steering device according to an embodiment of this application is as follows: the rotating component controls the rotation speed of the two drive wheels 41 respectively, enabling the device to move forward, backward, and differentially. The rotating motor 3 starts and drives the active bevel gear 31 to rotate. The active bevel gear 31 drives the two driven bevel gears 32 to rotate. The driven bevel gears 32 drive the second gear 35 to rotate through the coupling 33, and then drive the connecting block 4 to rotate through the first gear 34, so that the two drive wheels 41 can turn at the same time, enabling the device to move in multiple directions and improving the flexibility of the device.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
