[0047] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0048] The operating device according to the present application will be described below with reference to the accompanying drawings.
[0049] like Figures 1 to 6 As shown, an exemplary embodiment of the present application provides a manipulation device, which includes a base, a joystick 110, a shift mechanism, and a sensing mechanism. The joystick 110 is swingably arranged on the base, the shift mechanism includes a bracket and a spring-pressing assembly, one of which is connected to the base and the other is connected to the joystick 110, the bracket is provided with a plurality of shift protrusions arranged in sequence along the swing direction of the joystick 110, the joystick 110 can drive the bracket and the spring-pressing assembly to move relative to each other along the swing direction when swinging so that the spring-pressing assembly elastically presses any one of the shift protrusions, the sensing mechanism includes a magnet and a Hall element, the magnet can follow the swing of the joystick 110, and the Hall element is used to sense the magnetic field of the magnet to generate a trigger control signal.
[0050] If the bracket is connected to the base and the operating lever 110 is connected to the spring-pressing assembly, the operating lever 110 can drive the spring-pressing assembly to move between multiple shift protrusions when swinging, and finally the elastic assembly can press against any one of the shift protrusions to complete the shift; if the bracket is connected to the operating lever 110 and the spring-pressing assembly is connected to the base, the operating lever 110 can drive the bracket to move relative to the spring-pressing assembly when swinging, so that multiple shift protrusions move relative to the spring-pressing assembly, and finally any one of the shift protrusions can press against the elastic assembly to complete the shift.
[0051] Thus, the operator can make the magnet of the sensing mechanism follow the movement by pushing the joystick 110 to swing, and at the same time, the Hall element can generate a trigger control signal by sensing the magnetic field of the magnet, thereby controlling the host to adjust the operating state, such as controlling the host to move forward, backward or turn, etc. The key is that the bracket in the shift mechanism is provided with a plurality of shift protrusions corresponding to the plurality of gears of the host. During the swinging process of the joystick 110, the bracket and the spring-pressing assembly in the shift mechanism can be driven to move relative to each other along the swinging direction, so that the spring-pressing assembly can elastically press any one of the shift protrusions. When the spring-pressing assembly moves between different shift protrusions, the joystick 110 can feedback the resistance and vibration to the operator, so that the operator can sense the change of the gear, improve the accuracy of the gear adjustment, and ensure the operating safety of the controlled host.
[0052] It should be noted that when the magnet is installed on the joystick 110, it is necessary to ensure that there is enough space between it and the Hall element. Using the Hall effect, when the magnet swings with the joystick 110, the Hall element can sense the change in the corresponding magnetic field strength and generate a corresponding Hall voltage. The Hall voltage is proportional to the magnetic field strength in the conductor. By measuring the change in the Hall voltage, the displacement or angle change of the joystick 110 can be calculated, so as to control the host to make corresponding actions. In addition, it can be set that each swing of the joystick 110 by an angle change value is a gear change. For example, each swing of the joystick 110 by 5°, the spring pressure component moves from the previous shift protrusion to the next adjacent shift protrusion. The Hall element measures the angle change value of 5° when the joystick 110 swings, and immediately generates a trigger control signal to control the host to change the corresponding gear, such as one gear forward or one gear backward, so that the physical gear defined by the multiple shift protrusions corresponds to the electronic gear output by the Hall element. It can be seen that the sensing mechanism composed of magnets and Hall elements has high detection accuracy, which is conducive to the accurate detection of joystick motion signals.
[0053] In an optional or preferred embodiment, referring to Figure 1 , Figure 2 and Figure 4 The shift mechanism includes a first shift mechanism, which includes a first bracket 120 and a first spring-pressing assembly, wherein the first bracket 120 is provided with a plurality of first shift protrusions arranged in sequence along the first swing direction f of the operating lever 110, the sensing mechanism includes a first sensing mechanism, which includes a first magnet 140 and a first Hall element 312, and the operating device also includes a first rotating shaft 132.
[0054] Specifically, the first bracket 120 is connected to the base, the first rotating shaft 132 extends in a direction perpendicular to the first swing direction f and is rotatably connected to the first bracket 120, the joystick 110 is fixed to the first rotating shaft 132 by a through connection so that it can swing along the first swing direction f, the first spring-pressing assembly is connected to the inner end of the joystick 110 and elastically presses the first shift protrusion, the first magnet 140 is fixed to the end of the first rotating shaft 132, and the first Hall element 312 is arranged on the first bracket 120.
[0055] Thus, when the joystick 110 swings along the first swing direction f, the first spring pressing assembly can be driven to move along the arrangement direction of the plurality of first shifting protrusions, and the first spring pressing assembly is always pressed against the first shifting protrusions at the corresponding positions during the movement, thereby completing the shifting operation. At the same time, the first rotating shaft 132 rotates, which can drive the first magnet 140 to rotate, and the first Hall element 312 can sense the magnetic field change of the first magnet 140 to generate a first trigger control signal.
[0056] exist Figure 1 In the illustrated embodiment, the joystick 110 is disposed through the first bracket 120, and within the swing range of the joystick 110 along the first swing direction f, the first bracket 120 is formed with a corresponding avoidance cavity, so that the joystick 110 can swing relative to the first bracket 120. In other embodiments, the joystick 110 may also be disposed outside the first bracket 120, thereby eliminating the need to process the avoidance cavity of the first bracket 120 and reducing manufacturing costs.
[0057] It should be noted that in Figure 1 In the illustrated embodiment, the inner end of the joystick 110 is the end close to the base, and the outer end is the end away from the base and controlled by the operator. In the case where the joystick 110 passes through the first rotating shaft 132, the two can be connected and fixed by the spring pin 131. The first Hall element 312 can be supported and fixed on the first bracket 120 by the first element bracket 311, for example, the first element bracket 311 and the first bracket 120 can be connected by screws, or installed by other fixing methods such as plug-in, snap connection, hinge, etc. When the joystick 110 swings along the first swing direction f, the first Hall element 312 can send a forward control signal or a backward control signal, so that the host can be controlled to move forward or backward. In addition, whenever the joystick 110 moves forward or backward along the first swing direction f, the forward speed of the host can be controlled to speed up or slow down, or the backward speed of the host can be controlled to slow down or speed up by one gear. In other embodiments, when the joystick 110 swings along the first swing direction f, the first Hall element 312 may also send a control signal for left and right movement, thereby controlling the host to move along the left and right directions, which is not limited in the present application.
[0058] In addition, the base includes an upper frame 410, a middle frame 430 and a lower frame 440 which are arranged in sequence from top to bottom. Figure 1 In the illustrated embodiment, the first bracket 120 is disposed on the middle frame 430, and the upper frame 410 is formed with an escape hole for escaping the operating rod 110. The operating rod 110 disposed through the first bracket 120 can pass through the escape hole, so that the upper frame 410 can cover the top of the middle frame 430. Such an arrangement can make the structure of the operating device more solid and simple.
[0059] In an optional or preferred embodiment, referring to Figure 2 and Figure 4 The first bracket 120 is formed with a first curved groove 1201 arranged along the first swinging direction f, and a plurality of first shift protrusions are arranged in sequence on the first curved groove wall of the first curved groove 1201. The curvature radius of the first curved groove wall is greater than the curvature radius of the first rotating shaft 132, that is, the curvature of the first curved groove wall is smaller than the curvature of the first rotating shaft 132.
[0060] It should be noted that, in this embodiment, the first curved slot 1201 is a through slot, the joystick 110 is inserted into the first curved slot 1201, and a plurality of first shift protrusions are arranged on the bottom wall of the first bracket 120, that is, on the first curved slot wall of the first curved slot 1201.
[0061] When the joystick 110 is not subjected to any operating force, the joystick 110 is in an initial position, which may be the middle position of the first curved slot 1201 . The first spring-pressing assembly disposed at the inner end of the joystick 110 may be crimped onto the first shift protrusion located in the middle position of the first curved slot 1201 .
[0062] When the operating lever 110 is subjected to the first operating force, the operating lever 110 swings away from the initial position along the first swing direction f, and the elastic compression amount of the first elastic pressure component increases and moves toward other first shift protrusions away from the middle position.
[0063] Since the curvature radius of the first curved groove wall is greater than the curvature radius of the first rotating shaft 132, when the operating force on the joystick 110 is cancelled, the first elastic pressure component can be depressurized and stretched, driving the joystick 110 to swing along the first swing direction f close to the initial position until the joystick 110 is reset to the initial position, thereby realizing the automatic reset of the joystick 110. Of course, in some emergency situations, for example, the joystick 110 can also be reset by manually pushing the joystick 110 in the opposite direction. When the sensing mechanism detects that the joystick 110 is reset, it can stop generating a trigger control signal to control the host to stop the action.
[0064] In an optional or preferred embodiment, referring to Figures 2 to 4The first spring-pressing assembly includes a sliding sleeve 151, a first spring 152, a gasket 153 and a first retaining spring 154 which are sequentially sleeved on the operating rod 110 from the outside to the inside along the axial direction. The first retaining spring 154 is fixed to the operating rod 110 and abuts against the gasket 153. The first spring 152 is elastically pressed between the sliding sleeve 151 and the gasket 153. Under the elastic force of the first spring 152, the sliding sleeve 151 can keep pressing the first shifting protrusion.
[0065] The sliding sleeve 151 can be regarded as a slider that can slide along the first curved sliding groove 1201. Since the curvature of the first curved groove wall is smaller than the curvature of the first rotating shaft 132, when the joystick 110 swings away from the initial position along the first swinging direction f, the distance between the sliding sleeve 151 and the gasket 153 is further reduced. For this reason, the first spring 152 can be further compressed. The compressed first spring 152 can provide the driving force required for resetting the joystick 110. For details, please refer to the above-mentioned resetting process, which will not be repeated here.
[0066] In an alternative or preferred embodiment, see Figure 3 , two first magnets 140 and two first Hall elements 312 are provided, the two first magnets 140 are respectively fixed at the two ends of the first rotating shaft 132, and the two first Hall elements 312 are respectively arranged on both sides of the first bracket 120 to match the two first magnets 140, so that the two first Hall elements 312 can sense the swinging action of the joystick 110 along the first swinging direction f, thereby generating two corresponding trigger control signals to improve the detection accuracy. In addition, when one of the first Hall elements 312 fails, the joystick 110 can be sensed by using the other first Hall element 312, which can still ensure the issuance of a normal shift signal, thereby avoiding delays in the construction period due to the failure of the joystick 110.
[0067] In an optional or preferred embodiment, the shift mechanism also includes a second shift mechanism, which includes a second bracket 210 and a second spring-pressing assembly, wherein the second bracket 210 is provided with a plurality of second shift protrusions arranged in sequence along a second swing direction s of the joystick 110, and the second swing direction s is perpendicular to the first swing direction f, the sensing mechanism includes a second sensing mechanism, the second sensing mechanism includes a second magnet 240 and a second Hall element 322, and the operating device also includes a second rotating shaft 230.
[0068] Specifically, the second bracket 210 is fixed to the first bracket 120, thereby forming a connection with the joystick 110, the second shaft 230 is fixed to the first bracket 120 and is rotatably connected to the base; the second elastic pressure component is arranged on the base and elastically presses the second shift protrusion, the second magnet 240 is fixed to the end of the second shaft 230, and the second Hall element 322 is arranged on the base.
[0069] Thus, when the joystick 110 swings along the second swing direction s, the second bracket 210 can be driven to swing along the second swing direction s. At this time, the plurality of second shift protrusions move relative to the second spring pressing assembly, so that the second spring pressing assembly is pressed against different second shift protrusions, thereby completing the shifting operation. At the same time, the second rotating shaft 230 rotates, which can drive the second magnet 240 to rotate. The second Hall element 322 can sense the magnetic field change of the second magnet 240 and generate a second trigger control signal.
[0070] exist Figure 2 , Figure 4 Figure 6 In the illustrated embodiment, the second rotating shaft 230 is a split rotating shaft composed of two short shafts, and the two short shafts are respectively arranged on the two outer side walls of the first bracket 120 along the first swing direction f; the base includes an upper frame 410, a middle frame 430 and a lower frame 440 arranged in sequence from top to bottom, and a curved shaft groove for nesting the short shaft of the second rotating shaft 230 is formed on the top of the middle frame 430, and the outer ends of the two short shafts are sleeved with bearings 160, and the first bracket 120 is mounted in the middle frame 430 through the two short shafts, so that when the joystick 110 swings along the second swing direction s, it can drive the first bracket 120 and the second bracket 210 to swing relative to the base. The base also includes a bearing cover plate 420 for pressing the bearing 160, and the bearing cover plate 420 can cover the curved shaft groove of the middle frame 430 to press the bearing 160 located in the curved shaft groove to prevent the first bracket 120 from shaking and deviating from the initial position.
[0071] In addition, the second Hall element 322 can be fixed on the middle frame 430 through the second element bracket 321, for example, the second element bracket 321 and the middle frame 430 can be connected by screws, or installed by other fixing methods such as plug-in, snap connection, hinge, etc. When the joystick 110 swings along the second swing direction s, the second Hall element 322 can be triggered to generate a left turn control signal or a right turn control signal, thereby controlling the host to turn left or right. In other embodiments, when the joystick 110 swings along the second swing direction s, the second Hall element 322 can also send a control signal for forward and backward movement, thereby controlling the host to move in the forward and backward directions, which is not limited in this application.
[0072] In an optional or preferred embodiment, referring to Figure 2 and Figure 6 The second bracket 210 is formed with a second curved groove 2101 arranged along the second swinging direction s. Specifically, the second curved groove 2101 is formed at the bottom of the second bracket 210, and a plurality of second shift protrusions are arranged in sequence on the second curved groove wall of the second curved groove 2101. The curvature radius of the second curved groove wall is greater than the curvature radius of the second rotating shaft 230, that is, the curvature of the second curved groove wall is smaller than the curvature of the second rotating shaft 230.
[0073] When the operating lever 110 is not subjected to operating force, the operating lever 110 is in the initial position. When the operating lever 110 is in the initial position, the second spring-pressing assembly is pressed against the second shifting protrusion located in the middle of the second curved slot 2101 .
[0074] When the operating lever 110 is subjected to the second operating force, the operating lever 110 swings away from the initial position along the second swing direction s, and the elastic compression amount of the second elastic pressure assembly increases and moves toward other second shift protrusions away from the middle position.
[0075] Since the curvature radius of the second curved groove wall is greater than the curvature radius of the second rotating shaft 230, after the operating force acting on the joystick 110 is removed, the second elastic pressure component can release pressure and stretch, driving the joystick 110 to swing along the second swing direction s close to the initial position until the joystick 110 is reset to the initial position, thereby realizing automatic reset of the joystick 110.
[0076] In an alternative or preferred embodiment, see Figure 1 and Figure 5 The second spring-pressing assembly includes a guide column 223, a sleeve 221, a second spring 222, a guide bracket 224, and a second clip 225 that are sequentially sleeved on the guide column 223. The guide bracket 224 is fixedly connected to the base, and can be fixedly installed on the lower frame 440. The second clip 225 is fixed to the guide column 223 and abuts against the guide bracket 224. The second spring 222 is elastically pressed between the sleeve 221 and the guide bracket 224. Under the elastic force of the second spring 222, the sleeve 221 can keep pressing the second shift protrusion.
[0077] Since the curvature of the second curved groove wall is smaller than the curvature of the second rotating shaft 230, when the joystick 110 swings away from the initial position along the second swing direction s, the distance between the sleeve 221 and the guide bracket 224 is further reduced. For this reason, the second spring 222 can be further compressed. The compressed second spring 222 can provide the driving force required for resetting the joystick 110. For details, please refer to the above-mentioned resetting process, which will not be repeated here.
[0078] In an alternative or preferred embodiment, see Figure 1 and Figure 2, two second shafts 230, two second magnets 240 and two second Hall elements 322 are provided, the two second shafts 230 are fixed to the two sides of the first bracket 120, the two second magnets 240 are fixed to the outer ends of the two second shafts 230, and the two second Hall elements 322 are matched with the two second magnets 240 on the two sides of the base, so that the two second Hall elements 322 can sense the swinging action of the joystick 110 along the second swinging direction s, thereby generating two corresponding trigger control signals to improve the detection accuracy. In addition, when one of the second Hall elements 322 fails, the joystick 110 can be sensed by using the other second Hall element 322, which can still ensure the issuance of a normal shift signal, avoiding delays in the construction period due to the failure of the joystick 110.
[0079] In an alternative or preferred embodiment, see Figure 1 and Figure 2 The second shift mechanism is provided with two, and the two second shift mechanisms are arranged on both sides of the first bracket 120 along the first swing direction f. By providing two second shift mechanisms on both sides of the first bracket 120, the shift feel when the operator pushes the joystick 110 along the second swing direction s can be improved, and it is beneficial to improve the smoothness and stability of the shift.
[0080] The above content describes in detail the preferred specific embodiments of the present application.
