Moreover, the magnetic piece and the Hall sensing piece are always in a non-contact state, and the Hall sensing piece needing to be electrified can be independently packaged in the mounting cavity, so that the Hall sensing piece can be effectively prevented from being in contact with water, the waterproof performance is good, and the service life is prolonged.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a switch structure and a foot pedal controller. Background Technology

[0002] Foot pedal controllers primarily use foot movements to output corresponding control signals to control external devices to perform different operations. For example, during surgery, doctors can control the foot pedal controller with their feet, causing it to output different control signals to control medical equipment to perform different actions and thus complete the corresponding surgical procedure. However, traditional foot pedal controllers have poor waterproof performance, making them unsuitable for operation in humid environments such as those requiring frequent disinfection, thus affecting their lifespan. Utility Model Content

[0003] Therefore, it is necessary to provide a switch structure and foot pedal controller to address the problem of poor waterproof performance affecting service life.

[0004] The technical solution is as follows:

[0005] On the one hand, a switching structure is provided, including:

[0006] The foot pedal housing has a mounting hole that communicates with the outside, and the interior of the foot pedal housing also has a mounting cavity spaced apart from the mounting hole;

[0007] The pressing component is partially disposed in the mounting hole and moves in cooperation with the foot pedal housing, so that the pressing component can reciprocate between a first position and a second position relative to the foot pedal housing along the axial direction of the mounting hole;

[0008] A sensing component, comprising a magnetic element and a Hall effect sensor, wherein the magnetic element is connected to the pressing component and located within the mounting hole, and the Hall effect sensor is disposed within the mounting cavity;

[0009] When the pressing assembly moves relative to the foot pedal housing to the first position, the magnetic element and the Hall sensor are spaced apart along the axial direction of the mounting hole with a first distance, and the magnetic element and the Hall sensor are in a non-coupled state; when the pressing assembly moves relative to the foot pedal housing to the second position, the magnetic element and the Hall sensor are spaced apart along the axial direction of the mounting hole with a second distance, and the magnetic element and the Hall sensor are in a magnetic induction engagement state, and the second distance is smaller than the first distance.

[0010] The technical solution will be further explained below:

[0011] In one embodiment, the pressing assembly includes an elastic reset member and a pressing member. The pressing member is connected to the magnetic member. The elastic reset member is arranged along the axial direction of the mounting hole and disposed within the mounting hole. One end of the elastic reset member is connected to the foot pedal housing, and the other end of the elastic reset member is connected to the pressing member, so that the pressing member can reciprocate between a first position and a second position relative to the foot pedal housing along the axial direction of the mounting hole.

[0012] In one embodiment, the pressing assembly further includes a positioning sleeve and a sliding sleeve. The sliding sleeve is fitted onto the outer periphery of the pressing member and is fixedly connected to the pressing member. The positioning sleeve is located in the mounting hole and is fixedly connected to the foot pedal housing. The positioning sleeve is fitted onto the outer periphery of the sliding sleeve and slides in cooperation with the sliding sleeve.

[0013] In one embodiment, the inner wall of the sliding sleeve is provided with a first clearance groove, and the other end of the elastic reset member is located in the first clearance groove and sleeved on the outer periphery of the pressing member.

[0014] In one embodiment, the outer wall of the sliding sleeve is provided with a first abutment portion, and the positioning sleeve is provided with a second abutment portion. When the pressing member moves relative to the foot pedal housing to the first position, the first abutment portion and the second abutment portion engage in abutment.

[0015] In one embodiment, the pressing member has a third abutment on the side away from the Hall sensor, and the positioning sleeve has a fourth abutment. When the pressing member moves relative to the foot pedal housing to the second position, the third abutment and the fourth abutment engage in abutment.

[0016] In one embodiment, the outer wall of the third contact portion slides into contact with the inner wall of the mounting hole.

[0017] In one embodiment, the third contact portion is provided with a second clearance groove, and when the pressing member moves relative to the foot pedal housing to the second position, the positioning sleeve portion is located in the second clearance groove.

[0018] In one embodiment, the pressing member has a placement groove at one end near the Hall sensor, and the magnetic member is disposed in the placement groove.

[0019] On the other hand, a foot pedal controller is provided, including a pedal and the aforementioned switch structure, wherein the pedal is rotatably connected to the foot pedal housing.

[0020] In the switch structure and foot pedal controller of the above embodiments, when the pressing component is in the first position relative to the foot pedal housing, there is no signal transmission because the magnetic component and the Hall sensor are in a non-coupled state, thus the foot pedal controller is in a stopped state. When the pressing component is pressed and moves relative to the foot pedal housing to the second position, there is signal transmission because the magnetic component and the Hall sensor are in a magnetic induction engagement state, thus the foot pedal controller is in an activated state, thereby enabling control of the medical device. When the force applied to the pressing component disappears, the pressing component will return to the first position under the reset force of the elastic reset component. Furthermore, since the magnetic component and the Hall sensor are always in a non-contact state, and the Hall sensor that needs to be energized can be separately encapsulated in the mounting cavity, contact with water can be effectively avoided, resulting in good waterproof performance and extended service life.

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] like Figure 1 As shown, in one embodiment, a foot pedal controller 10 is provided, including a pedal 100 and a switch structure 200. The pedal 100 and the foot pedal housing 210 of the switch structure 200 are rotatably connected by means of hinge or other means. Thus, the start and stop of the foot pedal controller 10 can be operated and controlled by the switch structure 200, meeting usage requirements. Furthermore, the switch structure 200 has good waterproof performance, extending its service life.

[0029] It should be noted that the pedal 100 can be an existing box-shaped or other structure, which will not be described in detail here.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a switch structure 200 is provided, including a foot pedal housing 210, a pressing component 220, and a sensing component 230.

[0031] like Figure 2 As shown, the foot pedal housing 210 can be a plate-shaped or block-shaped structure. The foot pedal housing 210 has a mounting hole 212 that communicates with the outside. Furthermore, the foot pedal housing 210 also has a mounting cavity 211 that is spaced apart from the mounting hole 212. That is, the mounting cavity 211 and the mounting hole 212 are not interconnected.

[0032] like Figure 2 As shown, in one embodiment, the foot pedal housing 210 has a front facing the foot and a back spaced apart from the front and located inside it, wherein the front has a mounting hole 212 and the back has a mounting cavity 211.

[0033] like Figure 2 As shown, the pressing component 220 is partially disposed in the mounting hole 212, and the pressing component 220 is movably engaged with the foot pedal housing 210, thereby enabling the pressing component 220 to reciprocate between a first position and a second position relative to the foot pedal housing 210 along the axial direction of the mounting hole 212.

[0034] like Figure 2As shown, the sensing component 230 includes a magnetic element 231 and a Hall effect sensor 232. The magnetic element 231 is connected to the pressing component 220 and located within the mounting hole 212, allowing the magnetic element 231 to reciprocate axially with the pressing component 220 relative to the pedal 100 housing along the mounting hole 212. The Hall effect sensor 232 is disposed within the mounting cavity 211, such that the Hall effect sensor 232 and the magnetic element 231 are axially spaced apart from each other in the mounting hole 212.

[0035] like Figure 2 As shown, when the pressing component 220 moves to the first position relative to the foot pedal housing 210, the magnetic component 231 and the Hall sensor 232 are arranged at a first distance along the axial direction of the mounting hole 212. Furthermore, the magnetic component 231 and the Hall sensor 232 are in a non-coupled state, that is, the Hall sensor 232 is located outside the magnetic field range of the magnetic component 231, so that there is no signal transmission between the Hall sensor 232 and the magnetic component 231, and therefore no voltage signal or other acquisition signal is output to the outside.

[0036] When the pressing component 220 moves to the second position relative to the foot pedal housing 210, the magnetic component 231 and the Hall sensor 232 are spaced apart along the axial direction of the mounting hole 212 at a second distance. Furthermore, the magnetic component 231 and the Hall sensor 232 are in a magnetic induction engagement state, meaning the Hall sensor 232 is within the magnetic field range of the magnetic component 231. This allows for signal transmission between the Hall sensor 232 and the magnetic component 231, enabling the output of voltage signals and other acquired signals to operate and control the start and stop of the foot pedal controller 10. Moreover, the second distance is smaller than the first distance.

[0037] Optionally, the Hall sensor 232 can be a linear Hall sensor or a switch-type Hall sensor. The magnetic component 231 can be a magnetic component such as a permanent magnet.

[0038] It should be noted that the specific size of the first gap can be flexibly adjusted or designed according to the actual use, as long as the magnetic component 231 and the Hall sensor 232 are in a non-coupled state.

[0039] It should be noted that the specific size of the second gap can be flexibly adjusted or designed according to the actual use, as long as the magnetic component 231 and the Hall sensor 232 are in a magnetic induction engagement state.

[0040] It should be noted that the spacing between the mounting hole 212 and the mounting cavity 211 can be arranged relatively apart along the axial direction of the mounting hole 212, or it can be arranged in a staggered manner, as long as it allows the magnetic component 231 and the Hall sensor 232 to switch between a non-coupled state and a magnetically coupled state.

[0041] In the switch structure 200 of the above embodiment, when the pressing component 220 is in the first position relative to the foot pedal housing 210, there is no signal transmission because the magnetic component 231 and the Hall sensor 232 are in a non-coupled state, thus causing the foot pedal controller 10 to be in a stopped state. When the pressing component 220 is pressed and moves relative to the foot pedal housing 210 to the second position, there is signal transmission because the magnetic component 231 and the Hall sensor 232 are in a magnetic induction engagement state, thus causing the foot pedal controller 10 to be in an activated state, thereby enabling control of the medical device. When the force applied to the pressing component 220 disappears, the pressing component 220 will return to the first position under the reset force of the elastic reset component 221. Furthermore, since the magnetic component 231 and the Hall sensor 232 are always in a non-contact state, and the Hall sensor 232, which requires power, can be separately encapsulated in the mounting cavity 211, it can effectively avoid contact with water, providing good waterproof performance and extending service life.

[0042] like Figure 2 As shown, in one embodiment, the pressing assembly 220 includes an elastic reset member 221 and a pressing member 222. The pressing member 222 is connected to a magnetic member 231, thereby enabling the pressing member 222 to drive the magnetic member 231 to reciprocate relative to the pedal 100 housing along the axial direction of the mounting hole 212. The elastic reset member 221 is arranged axially along the mounting hole 212 and disposed within the mounting hole 212. One end of the elastic reset member 221 is connected to the pedal housing 210, and the other end is connected to the pressing member 222, allowing the pressing member 222 to reciprocate relative to the pedal housing 210 along the axial direction of the mounting hole 212 between a first position and a second position.

[0043] It should be noted that, in order to facilitate pressing the pressing member 222, the pressing member 222 is at least partially or completely exposed outside the foot pedal housing 210 when not subjected to external force, so as to facilitate operation.

[0044] Specifically, when no force is applied to the pressing member 222, the elastic reset member 221 applies force or supports the pressing member 222 to be in the first position relative to the foot pedal housing 210, so that the magnetic member 231 and the Hall sensor 232 are arranged relatively apart along the axial direction of the mounting hole 212 with a first gap. At this time, the magnetic member 231 and the Hall sensor 232 are in a non-coupled state, that is, the Hall sensor 232 is outside the magnetic field range of the magnetic member 231, so that there is no signal transmission between the Hall sensor 232 and the magnetic member 231, and therefore no voltage signal or other acquisition signal is output to the outside. When a force is applied to the pressing member 222 in the direction of the Hall sensor 232, the pressing member 222 overcomes the force of the elastic reset member 221 and moves relative to the foot pedal housing 210 to a second position. This causes the magnetic member 231 and the Hall sensor 232 to be spaced apart axially along the mounting hole 212 at a second distance. At this time, the magnetic member 231 and the Hall sensor 232 are in a magnetic induction engagement state, meaning the Hall sensor 232 is within the magnetic field range of the magnetic member 231. This allows for signal transmission between the Hall sensor 232 and the magnetic member 231, enabling the output of voltage signals and other acquisition signals to operate and control the start and stop of the foot pedal controller 10. When the force applied to the pressing member 222 disappears, the pressing member 222 will return to the first position under the reset force of the elastic reset member 221.

[0045] Optionally, the pressing element 222 can be in the form of a button or the like.

[0046] Optionally, the elastic reset member 221 can be an elastic component such as a spring.

[0047] like Figure 2 As shown, the pressing assembly 220 further includes a positioning sleeve 223 and a sliding sleeve 224. The sliding sleeve 224 is fitted onto the outer periphery of the pressing member 222 and is fixedly connected to the pressing member 222 by means of an interference fit or other means, thereby allowing the sliding sleeve 224 to reciprocate synchronously with the pressing member 222 along the axial direction of the mounting hole 212. The positioning sleeve 223 is located inside the mounting hole 212 and is fixedly connected to the foot pedal housing 210 by means of an interference fit or other means. The positioning sleeve 223 is fitted onto the outer periphery of the sliding sleeve 224 and slides within the sliding sleeve 224. Thus, the sliding fit between the positioning sleeve 223 and the sliding sleeve 224 guides the movement of the pressing member 222 relative to the foot pedal housing 210, making the movement of the pressing member 222 relative to the foot pedal housing 210 more stable, avoiding radial swaying, and making the movement of the pressing member 222 relative to the foot pedal housing 210 more accurate, ensuring that the pressing member 222 accurately reciprocates between the first position and the second position along the axial direction of the mounting hole 212.

[0048] In one embodiment, the central axis of the positioning sleeve 223, the central axis of the sliding sleeve 224, and the central axis of the mounting hole 212 are collinear, making the movement of the pressing member 222 relative to the foot pedal housing 210 more stable and accurate.

[0049] like Figure 2 As shown, in one embodiment, the inner wall of the sliding sleeve 224 is provided with a first clearance groove 2241. Furthermore, the other end of the elastic reset member 221 is located within the first clearance groove 2241 and sleeved on the outer periphery of the pressing member 222. In this way, the elastic reset member 221 can be sleeved onto the pressing member 222, and the groove wall of the first clearance groove 2241 can hold the elastic reset member 221 tightly, preventing it from falling off the pressing member 222. Moreover, during assembly, it is only necessary to insert the end of the elastic reset member 221 into the first clearance groove 2241 and sleeve it onto the outer wall of the pressing member 222, which is simple, convenient, and easy to assemble.

[0050] like Figure 2 As shown, in one embodiment, the outer wall of the sliding sleeve 224 is provided with a first abutment portion 2242, and the positioning sleeve 223 is provided with a second abutment portion 2231. When the pressing member 222 moves relative to the foot pedal housing 210 to the first position, the first abutment portion 2242 and the second abutment portion 2231 engage in abutment. Thus, by utilizing the engagement between the first abutment portion 2242 and the second abutment portion 2231, the pressing member 222 is accurately held in the first position relative to the foot pedal housing 210, ensuring that the magnetic member 231 and the Hall sensor 232 are in a non-coupled state. Furthermore, at this time, the elastic reset member 221 can be in a partially compressed state, thereby making the engagement between the first abutment portion 2242 and the second abutment portion 2231 tighter and the limiting effect better.

[0051] Optionally, the contacting fit between the first contacting part 2242 and the second contacting part 2231 can be a contacting fit between a flange and a boss, or a contacting fit between a protrusion and a ring.

[0052] like Figure 2 As shown, further, the pressing member 222 has a third contact portion 2221 on the side away from the Hall sensor 232, and the positioning sleeve 223 has a fourth contact portion 2232. When the pressing member 222 moves relative to the foot pedal housing 210 to the second position, the third contact portion 2221 and the fourth contact portion 2232 engage in contact. Thus, by utilizing the engagement between the third contact portion 2221 and the fourth contact portion 2232, the pressing member 222 is accurately held in the second position relative to the foot pedal housing 210, ensuring that the magnetic member 231 and the Hall sensor 232 are in a magnetically inductive engagement state. Furthermore, at this time, the elastic reset member 221 can be in a maximum compressed state, which facilitates the pressing member 222 returning to the first position.

[0053] Optionally, the contacting fit between the third contacting part 2221 and the fourth contacting part 2232 can be a contacting fit between a flange and a boss, or a contacting fit between a protrusion and a ring.

[0054] like Figure 2 As shown, further, the outer wall of the third contact portion 2221 slides into the inner wall of the mounting hole 212. Thus, by utilizing the sliding engagement between the outer wall of the third contact portion 2221 and the inner wall of the mounting hole 212, the movement of the pressing member 222 relative to the foot pedal housing 210 can be guided and limited, making the movement of the pressing member 222 relative to the foot pedal housing 210 more stable, avoiding radial wobbling, and also making the movement of the pressing member 222 relative to the foot pedal housing 210 more accurate, ensuring that the pressing member 222 accurately reciprocates between the first position and the second position along the axial direction of the mounting hole 212.

[0055] like Figure 2 As shown, the third contact portion 2221 is further provided with a second clearance groove 22211. Furthermore, when the pressing member 222 moves relative to the foot pedal housing 210 to the second position, the positioning sleeve 223 is partially located within the second clearance groove 22211. This ensures that the positioning sleeve 223 has sufficient overlap area with the sliding sleeve 224 in the axial direction, improving the guiding and limiting effect on the movement of the pressing member 222 relative to the foot pedal housing 210. This makes the movement of the pressing member 222 relative to the foot pedal housing 210 more stable, preventing radial wobbling, and also makes the movement of the pressing member 222 relative to the foot pedal housing 210 more accurate, ensuring that the pressing member 222 accurately reciprocates between the first and second positions along the axial direction of the mounting hole 212.

[0056] like Figure 2 As shown, the pressing member 222 has a placement groove 2222 at one end near the Hall sensor 232, and the magnetic member 231 is disposed in the placement groove 2222. Thus, after the magnetic member 231 is installed in the placement groove 2222 by snap-fit ​​or plug-in method, the magnetic member 231 can reciprocate synchronously with the pressing member 222 along the axial direction of the mounting hole 212. Furthermore, this simplifies the assembly method of the magnetic member 231 and the pressing member 222, improving assembly and disassembly efficiency.
