[0027] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0030] Furthermore, although specific embodiments have been described herein, it should be understood that these embodiments are merely examples of the principles and applications of the invention. Therefore, it should be understood that many modifications can be made to the exemplary embodiments, and other arrangements can be designed without departing from the spirit and scope of the invention as defined by the appended claims. It should be understood that different dependent claims and features herein can be combined in ways not used as described in the original claims. It is also understood that features described in conjunction with individual embodiments can be used in other embodiments.

[0031] To solve the above problems, such as Figures 1 to 6 As shown, the present invention provides a pedal mechanism, a brake mechanism, and a locking mechanism 4. The locking mechanism 4 includes a trigger assembly 41, a locking hook 43, a locking head 44, a second spring 45, and a spring 46. The locking hook 43 is connected to the side of the chassis 11 and rotates about a direction perpendicular to the side of the chassis 11. The spring 46 is connected to the side of the chassis 11 and is used to extend and retract in the vertical direction, and is fixed at the longest or shortest point. The trigger assembly 41 is slidably connected to the side of the chassis 11 in the vertical direction and is used to drive the locking hook 43 to rotate and drive the spring 45. The jumper 46 extends and retracts. The two ends of the second spring 45 are respectively connected to the chassis 11 and the locking hook 43 and are used to drive the locking hook 43 to reset. The pedal mechanism is slidably connected to the chassis 11 in the vertical direction. The locking head 44 is connected to the bottom of the pedal mechanism and is used to engage with the locking hook 43 when the pedal mechanism is in the depressed state. The bottom of the pedal mechanism is provided with a first trigger part and a second trigger part. The first trigger part and the second trigger part are respectively used to drive the trigger assembly 41 to extend and retract in the vertical direction and to drive the brake mechanism to achieve braking when the pedal mechanism is depressed.

[0032] In the embodiment, the locking hook 43 is rotatable around the X axis, the mechanism of the elastic bouncer 46 can refer to the pressing end structure of a ballpoint pen, and can vertically extend and retract under the driving of external force and be locked when compressed to the shortest or stretched to the longest. A trigger assembly 41 is further arranged to slide up and down relative to the side of the chassis 11 along the Z axis. When the trigger assembly 41 moves downward, it contacts the locking hook 43 and the elastic bouncer 46, and drives the elastic bouncer 46 to shorten, and the locking hook 43 rotates clockwise. The other side of the locking hook 43 relative to the trigger assembly 41, that is, the side of the Y axis negative direction, is provided with a second spring 45, one end of which is connected to the locking hook 43, and the other end is connected to the side of the chassis 11. When the trigger assembly 41 is not working, the second spring 45 can pull the locking hook 43 to rotate counterclockwise to return to the original position. An upper portion of the trigger assembly 41 is provided with a pedal mechanism that can slide up and down relative to the chassis 11 along the Z axis. The pedal mechanism is connected with a lock head 44 at the bottom, and further includes a first trigger portion and a second trigger portion. The first trigger portion, the second trigger portion and the connection position of the lock head 44 at the bottom of the pedal mechanism are different from each other. When the pedal mechanism moves downward, the first trigger portion drives the trigger assembly 41 to move downward and contact the locking hook 43, and drives the locking hook 43 to rotate clockwise. The lock head 44 moves downward with the pedal mechanism, and the locking hook 43 that rotates clockwise is just buckled above the lock head 44 to realize the clamping of the locking hook 43 and the lock head 44. In this process, the trigger assembly 41 contacts the elastic bouncer 46, and drives the elastic bouncer 46 to shorten. When the locking hook 43 is just buckled above the lock head 44, the elastic bouncer 46 is shortened to the shortest, and the pedal mechanism cannot continue to move downward. The second trigger portion drives the brake mechanism to brake. At this time, the elastic bouncer 46 is locked at the shortest, the pedal mechanism is locked by the locking hook 43 to keep being stepped down, and the whole device is in a fixed state, so as to realize the braking of the medical operation platform. When unlocking is needed, the doctor steps on the pedal mechanism again and then releases it. After the elastic bouncer 46 is stressed, it is unlocked and elongated, drives the trigger assembly 41 and the pedal mechanism to move upward, the locking hook 43 rotates counterclockwise under the tension of the second spring 45, the locking hook 43 is separated from the lock head 44, the lock head 44 moves upward with the pedal mechanism, the brake mechanism is away from the universal wheel 12, and the unlocking of the medical operation platform is realized. The brake of the universal wheel 12 and the medical operation platform is realized by the mechanical structure, instead of the electromagnetic brake. The mechanical structure is not affected by external factors such as temperature and moisture, has stable structure, can be continuously used, and improves the stability of the brake device.

[0033] Specifically, the second spring 45 can be connected with the locking hook 43 through a bolt. The chassis 11 is provided with a slot structure for the locking mechanism 4.

[0034] Optionally, as Figure 1 and Figure 3As shown, the braking mechanism includes a brake pressure plate 31 and a first spring 32. The end of the brake pressure plate 31 away from the locking mechanism 4 is rotatably connected to the chassis 11. A brake ring 33 is provided on the brake pressure plate 31. The brake ring 33 is sleeved around the circumference of the universal wheel 12 and is used to abut against the outer circumferential surface of the universal wheel 12. One end of the first spring 32 is connected to the middle of the brake pressure plate 31, and the other end is used to connect to the lower surface of the chassis 11. The second trigger part is drivenly connected to the end of the brake pressure plate 31 near the locking mechanism 4.

[0035] In this embodiment, a brake pressure plate 31 is provided below the chassis 11. One end of the brake pressure plate 31 is rotatably connected to the rear of the chassis 11 (i.e., the end of the chassis 11 facing the positive Y-axis). A first spring 32 is provided in the middle of the brake pressure plate 31, and the other end of the first spring 32 is connected to the chassis 11. The first spring 32 pulls the brake pressure plate 31, so that the end of the brake pressure plate 31 away from the rear of the chassis 11 is higher in the Z-axis direction than the end of the brake pressure plate near the rear of the chassis 11. The 1 is also equipped with a brake ring 33, which is sleeved around the universal wheel 12. When the doctor steps on the pedal mechanism, the second trigger part contacts the end of the brake pressure plate 31 away from the rear of the chassis 11 and presses the brake pressure plate 31 to move downward. During this process, the brake pressure plate 31 rotates with its connection point with the rear of the chassis 11 as the center, and the brake ring 33 moves downward accordingly until it comes into contact with the outer peripheral surface of the universal wheel 12. The friction generated by the contact between the brake ring 33 and the universal wheel 12 causes the universal wheel 12 to stop moving.

[0036] Specifically, the longer brake pressure plate 31 is divided into two shorter extension plates 311 and brake plates 312. The extension plates 311 and brake plates 312 can be connected by bolts. The shorter structure is easier to process and form, reducing the processing difficulty of the brake pressure plate 31.

[0037] Optionally, such as Figure 5 As shown, the trigger assembly 41 includes a trigger bracket 411 and a push block 412. The trigger bracket 411 is used to drive the bouncing device 46 to extend and retract. The push block 412 is connected to the lower end of the trigger bracket 411 and extends toward the locking hook 43. The push block 412 is used to drive the locking hook 43 to rotate.

[0038] In the embodiment, the side of the chassis 11, below the pedal mechanism, is provided with a trigger bracket 411, which is slidingly connected with the side of the chassis 11 in the Z-axis direction. When the pedal mechanism moves downward, the first trigger part contacts the trigger bracket 411 and presses the trigger bracket 411 to move downward. The lower end of the trigger bracket 411 is connected with a pushing block 412, which extends toward the direction of the lock hook 43. The pushing block 412 moves downward with the trigger bracket 411 and contacts the lock hook 43. The force of the pushing block 412 to the lock hook 43 is greater than the force of the second spring 45 to the lock hook 43. The pushing block 412 drives the lock hook 43 to rotate clockwise, and the clamping of the lock hook 43 and the lock head 44 is completed.

[0039] Optionally, as shown in Figure 3 and Figure 7 , the tail of the chassis 11 is provided with a force balance mechanism, which includes a connecting base 51, a limiting block 52, a bearing and a third spring 53. The connecting base 51 is connected with the chassis 11. The connecting base 51 is provided with two bearing seats 54 which are spaced apart. The bearing seats 54 are provided with shaft holes 55. The bearing is arranged in the two shaft holes 55. The limiting block 52 is sleeved on the bearing. The end of the brake pressing plate 31 away from the pedal mechanism is connected with the limiting block 52. One end of the third spring 53 is connected with the bottom of the connecting base 51. The other end of the third spring 53 is connected with the end of the brake pressing plate 31 away from the pedal mechanism. The shaft hole 55 is provided with a sliding groove which extends in the vertical direction. The bearing is used to slide in the sliding groove.

[0040] In the embodiment, as shown in Figure 7As shown, the tail of the chassis 11 extends downwardly to be provided with a connecting base 51, the connecting base 51 is provided with a bearing seat 54 on the side facing the X-axis positive and negative ends, and the bearing seat 54 is provided with a bearing hole coaxially arranged and extending along the X-axis direction, and the bearing hole is provided with a bearing, and a limiting block 52 is sleeved on the bearing, the limiting block 52 is located between the two bearing seats 54, and the limiting block 52 can rotate around the bearing, and the brake pressing plate 31 is connected to the limiting block 52 on the side facing the Y-axis positive direction, so that the brake pressing plate 31 can rotate with the limiting block 52 around the bearing, that is, the brake pressing plate 31 can rotate relative to the tail of the base, and the third spring 53 is arranged between the bottom of the connecting base 51 and the brake pressing plate 31, and the bearing hole extends upwardly along the Z-axis direction to be provided with a sliding groove, so that the bearing can move in the sliding groove along the Z-axis direction, in order to brake the universal wheel 12, the brake ring 33 needs to give the universal wheel 12 a force, which is recorded as F, and the contact point of the brake ring 33 and the universal wheel 12 is the force point, which is recorded as a, since the universal wheel 12 can rotate by 360 degrees, the position of the force point a may change, for example, when the universal wheel 12 rotates to be close to the tail (Y-axis positive direction), the outer peripheral wall of the universal wheel 12 is used to contact the rear end inner wall of the brake ring 33, at this time, the force point a is relatively rear, when the universal wheel 12 rotates to be close to the head (Y-axis negative direction), the outer peripheral wall of the universal wheel 12 is used to contact the front end inner wall of the brake ring 33, at this time, the force point a is relatively front, no matter where the universal wheel 12 rotates, F remains unchanged, F is given by the force f1 of the doctor stepping on the pedal 26 to the side of the brake pressing plate 31 facing the Y-axis negative direction and the force f2 of the connecting base 51 pulling the brake pressing plate 31 to the side facing the Y-axis positive direction, in the braking state, the moments of f1 and f2 are equal to achieve the stable balance state of the brake pressing plate 31, the distance from the side of the brake pressing plate 31 facing the Y-axis negative direction to a is the force arm of f1, which is recorded as d1, the distance from the side of the brake pressing plate 31 facing the Y-axis positive direction to a is the force arm of f2, which is recorded as d2, when the brake ring 33 presses the universal wheel 12, the point a serves as the fulcrum of the lever, and the brake pressing plate 31 rotates around the point a, when the universal wheel 12 rotates to different positions, the force point a of F on the brake ring 33 is different, and the positions of d1 or d2 relative to the point a need to change to realize the force balance of the brake pressing plate 31, for example, when the universal wheel 12 rotates to the side facing the Y-axis negative direction, d1 is minimum and d2 is maximum;When the omnidirectional wheel 12 rotates to the end facing the positive Y-axis, d2 is at its minimum and d1 is at its maximum. A third spring 53 is provided between the bottom of the connecting base 51 and the end connected to the brake pressure plate 31 and the limiting block 52. The brake pressure plate 31 can pull the bearing to move up and down in the bearing hole, causing the third spring 53 to extend. This adjusts the force f2 exerted by the third spring 53 on the brake pressure plate 31, as well as the rotation angle of the f2 end. This achieves the effect that no matter how the position of point a changes, the force f1 applied by the doctor's foot and the rotation angle of the f1 end remain constant regardless of the position of the omnidirectional wheel 12. The doctor can use the same force to press the foot pedal 26 to complete braking and unlocking, improving the user experience.

[0041] Specifically, a groove 56 structure is provided on the connecting base plate, and a third spring 53 is disposed in the groove 56 structure. There can be multiple third springs 53.

[0042] Optionally, such as Figure 1 As shown, the brake pressure plate 31 is provided with a universal ball 34 at one end near the pedal mechanism, and the second trigger part is used to abut against the universal ball 34.

[0043] In this embodiment, by providing a universal ball 34 at one end of the brake pressure plate 31 to the pedal mechanism, i.e., in the negative direction of the Y-axis, when the pedal mechanism moves downward, the second trigger part contacts the universal ball 34, driving the universal ball 34 to move downward. The universal ball 34 can rotate, which can reduce the friction between the pedal mechanism and the brake pressure plate 31, making it easier to drive the brake pressure plate 31 to move downward.

[0044] Optionally, such as Figures 1 to 3 As shown, the chassis 11 is provided with a first slide rail 24 extending in a vertical direction. The pedal mechanism includes a foot pedal bracket 25, a foot pedal 26, a pedal pressure plate 27, and a slider. The slider is slidably connected to the first slide rail 24. The foot pedal bracket 25 includes a horizontal end and a vertical end. The vertical end is connected to the slider. The foot pedal 26 is connected to the upper surface of the horizontal end. The pedal pressure plate 27 is connected to the bottom of the horizontal end.

[0045] In this embodiment, a first slide rail 24 extending vertically is provided on the chassis 11, and a slider that cooperates with the first slide rail 24 is sleeved on the slide rail. The foot pedal bracket 25 includes a horizontal end and a vertical end that are perpendicular to each other. The vertical end is connected to the slider, so that the foot pedal bracket 25 can slide in the vertical direction. The bottom part of the horizontal end of the foot pedal bracket 25 is a first trigger part, and the other part is connected to the pedal pressure plate 27. The second trigger part is located on the pedal pressure plate 27. A through hole is provided on the chassis 11 for the pedal pressure plate 27 to pass through. The foot pedal 26 is set on the upper surface of the horizontal end. When the doctor steps on the foot pedal 26, the horizontal end, the vertical end, and the slider are driven to slide along the Z-axis direction on the first slide rail 24, so that the second trigger part drives the braking mechanism.

[0046] Specifically, the chassis 11 is provided with a slide rail mounting frame 28 extending in the vertical direction to provide a mounting position for the first slide rail 24, and the first slide rail 24 is connected to the slide rail mounting frame 28, thereby improving the stability of the connection between the first slide rail 24 and the chassis 11.
