[0033] Referring to Figures 2 to 6 The following embodiments of the present application provide an operation feedback device, a feedback switch device and a feedback adjustment device. The operation feedback device of the present application is installed on one side of the operation part close to the base, and moves synchronously with the operation part. When the operator controls the movement of the operation part, the guide rail moves synchronously, and the feedback insert fixed at the end of the connecting rod is inserted into the corresponding groove on the surface of the guide rail, thereby realizing the operation feedback of the operator. Since the guide rail is installed between the operation part and the base, the guide rail no longer occupies the operation space when it moves with the operation part, which is beneficial to the miniaturization of the entire device. At the same time, the feedback switch device is used to realize the opening or closing of the operation feedback function, which can effectively adapt to different use environments. The feedback adjustment device can realize the adjustment of different scale forces, which can effectively adapt to different use conditions.

[0034] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings of the embodiments of the present application.

[0035] As Figure 2 and Figure 6As shown, the embodiment provides an operation feedback device, comprising: a base 1 for mounting parts and supporting the operation feedback device; an operation part 2 located on one side of the base 1 and rotationally connected with the side surface of the base 1; a guide rail 3 fixedly installed on the side of the operation part 2 close to the base 1 and moving synchronously with the operation part 2; a connecting rod 4 rotationally connected with the base 1 at one end; wherein the other end of the connecting rod 4 is provided with a feedback insert 5, and the connecting rod 4 is applied with a force towards the guide rail 3 so that the feedback insert 5 is in close contact with the surface of the guide rail 3, and a plurality of grooves 301 are arranged on the surface of the guide rail 3 at intervals, the grooves 301 are matched with the feedback insert 5, when the operation part 2 is rotated to drive the guide rail 3 to move, the feedback insert 5 is inserted into the groove 301 at the corresponding position on the guide rail 3 to realize operation feedback.

[0036] In the embodiment, when the operator needs to operate, the operation part 2 is rotated by hand, and the guide rail 3 moves synchronously with the operation part 2. Since the feedback insert 5 at the other end of the connecting rod 4 is in contact with the surface of the guide rail 3, when the guide rail 3 moves to the corresponding position with the operation part 2, the feedback insert 5 at the end of the connecting rod 4 is instantly inserted into the groove 301 on the surface of the guide rail 3, thereby realizing the feedback of sound and touch and the positioning function during operation. When the operator continues to rotate the operation part 2, the guide rail 3 continues to rotate with the operation part 2, so that the feedback insert 5 is separated from the groove on the surface of the guide rail 3, and until the guide rail 3 moves to the feedback position of the next groove 301, the feedback insert 5 is re-inserted into the next groove 301 to realize operation feedback.

[0037] On the other hand, in the above-mentioned operation feedback device, referring to Figure 6 , since all the parts of the whole device are installed in the space between the base 1 and the operation part 2, and do not need to be separately installed in the operation part 2 to occupy the operation space, the occupation of the operation space is effectively reduced, and the movement of the guide rail 3 following the operation part 2 does not limit the use of the operation part 2, so that the design of the whole device is more simple and beautiful, and the operator can operate more conveniently.

[0038] Specifically, referring to Figure 1 and Figure 6 , in the prior art, Figure 1 , the distance at the A1 position is usually 5mm, and the movement structure is visible, the parts layout is compact and cannot be further provided with a scale display; and in the scheme of the present application, Figure 6The spacing at the B1 position can reach 18.5mm, and other functions such as scale display can be set without interfering with the movement results. Compared with the existing technology, the solution of this application can significantly reduce the encroachment on the operating space and facilitate the operator's use.

[0039] In some embodiments, a mounting portion 101 is installed on the base 1, the operating portion 2 is rotatably connected to the mounting portion 101, one end of the connecting rod 4 is rotatably connected to the base 1 through a first pin 401, and the feedback insert 5 is rotatably connected to the other end of the connecting rod 4 through a second pin 402.

[0040] In this embodiment, since the base 1 is provided with a mounting portion 101, the operating portion 2 can be easily rotated around the mounting portion 101 during operation, and one end of the connecting rod 4 is rotatably connected to the base 1 via the first pin 401, so that the connecting rod 4 can be easily rotated around the base 1 via the first pin 401. Similarly, the feedback insert 5 is rotatably connected to the other end of the connecting rod 4 via the second pin 402, thereby ensuring that the feedback insert 5 can rotate freely. When the feedback insert 5 is embedded in the groove 301, it can rotate freely to reduce the friction between the feedback insert 5 and the groove 301, thereby ensuring that the feedback insert 5 moves more smoothly in the groove 301, reducing the resistance of the guide rail 3 when following the movement of the operating portion 2, and making the operator's operation of the operating portion 2 smoother.

[0041] Furthermore, the surface of the guide rail 3 where the groove 301 is provided is configured as an arc structure.

[0042] In this embodiment, since the movement of the operating portion 2 generally involves rotational motion around the base 1, to ensure that the guide rail 3 maintains stable contact with the feedback insert 5 as it follows the movement of the operating portion 2, the side of the guide rail 3 where the groove 301 is provided is configured as an arc-shaped structure. This ensures that the guide rail 3 maintains stable contact with the feedback insert 5 as it moves synchronously with the operating portion 2, thereby ensuring that the feedback insert 5 consistently provides good feedback during the movement of the guide rail 3. Furthermore, the friction between the feedback insert 5 and the surface of the guide rail 3 is reduced, allowing the guide rail 3 to quickly switch between different feedback functions at different scales.

[0043] In some other embodiments, scale lines are provided on the surface of the base 1, a pointer is installed on the outer wall of the operating part 2, the guide rail 3 is in a stationary state relative to the operating part 2, and the grooves 301 provided on the guide rail 3 correspond one-to-one to the scale lines.

[0044] In the embodiment, since the operator realizes the operation control by controlling the operation part 2, in order to further improve the accuracy of the operation part 2 in operation control, a scale line corresponding to the groove 301 is arranged on the surface of the base 1, when the operator controls the operation part 2, the pointer also moves synchronously, each time the operation part 2 moves to the scale line at the corresponding position, the pointer on the operation part 2 also moves to the corresponding scale line position, the feedback insert 5 at the end of the connecting rod 4 matches and inserts the groove 301 on the current scale line, thereby realizing scale feedback, so that the operator can obtain good scale feedback each time when controlling the operation part 2, thereby realizing good scale feedback function, facilitating the operator to control.

[0045] It should be noted that the groove 301 arranged on the guide rail 3 can also correspond to the scale line part, for example, the scale line is 0-20cm, and the groove 301 is arranged at positions corresponding to the scale line of 5cm, 10cm, 15cm and 20cm, so that the guide rail 3 can maintain good operation feedback after moving to positions of integral multiples of 5, facilitating the operator to understand the current operation situation.

[0046] Further, the feedback insert 5 is a bearing matched with the groove 301.

[0047] By arranging the feedback insert 5 as a bearing matched with the groove 301, the feedback insert 5 can enter the groove 301 more smoothly each time, reducing frictional resistance and ensuring the accuracy of scale feedback.

[0048] For example, the bearing adopted by the feedback insert 5 in the application is a deep groove ball bearing, which has the advantages of flexible rotation and small frictional force, and if heavy load is required, a needle bearing can also be used, and the bearing with corresponding functions can be selected according to the actual situation, which is not particularly limited in the present scheme, and will not be described here.

[0049] The application further discloses a feedback switch device, referring to Figure 2 and Figure 3 applied to the operation feedback device, the feedback switch device comprises a switch assembly 6 mounted above the base 1, the switch assembly 6 is used for controlling the rotation of the connecting rod 4 in a sliding manner and adjusting the distance between the feedback insert 5 and the guide rail 3, so as to realize the opening or closing of the operation feedback function of the operation part 2.

[0050] On the basis of the operation feedback device, the feedback switch device is further arranged, and the operation feedback function of the entire operation feedback device is realized by the feedback switch device, so that whether the operation feedback function is opened or not can be freely selected, thereby facilitating the use in different working conditions.

[0051] Specifically, the switch assembly 6 installed on the base 1 remains stationary in the normal state to keep the operation feedback function open, and when the operation feedback function needs to be closed, the switch assembly 6 is pushed to slide on the base 1, so that the connecting rod 4 rotates and the feedback insert 5 at the end of the connecting rod 4 is separated from the surface of the guide rail 3 to close the operation feedback function, meeting the use under different conditions.

[0052] In some embodiments, the base 1 is provided with a switch part 102, the top of the switch part 102 is provided with a sliding groove 103, the switch assembly 6 includes a sliding block 601 slidingly arranged in the sliding groove 103, the bottom end of the sliding block 601 is provided with a push block 602, the end of the connecting rod 4 away from the feedback insert 5 is provided with a limiting block 403, and the sliding block 601 is pressed against the limiting block 403 after sliding along the inner wall of the sliding groove 103 to drive the connecting rod 4 to rotate and make the feedback insert 5 disengage from the groove 301.

[0053] In this embodiment, when the operation feedback function needs to be closed, the operator pushes the sliding block 601 to move in a first direction X away from the feedback insert 5 at the end of the connecting rod 4, and the push block 602 at the bottom is also moved under the driving action of the sliding block 601, and the push block 602 continuously moves to press the limiting block 403 at the end of the connecting rod 4 to drive the limiting block 403 to flip in a second direction Y, thereby driving the connecting rod 4 to flip in the second direction Y, so that the feedback insert 5 originally adhered to the surface of the guide rail 3 is separated from the surface of the guide rail 3, thereby closing the feedback function of the entire operation feedback device. When it needs to be opened, the operator only needs to push the sliding block 601 to slide in the sliding groove 103 in the direction opposite to the first direction X, so as to cancel the pushing action on the limiting block 403, and since the connecting rod 4 has a restoring force towards the surface of the guide rail 3, the feedback insert 5 at the end of the connecting rod 4 is repositioned to recontact the surface of the guide rail 3, so that the feedback insert 5 plays a role in operation feedback when the operation part 2 moves along with the guide rail 3 during subsequent operation.

[0054] In the above scheme, the sliding block 601 is arranged to slide inside the chute 103, and the push block 602 at the bottom of the sliding block 601 pushes the limiting block 403 mounted at the end of the connecting rod away from the feedback insert 5, so that the connecting rod 4 drives the feedback insert 5 to separate from the surface of the guide rail 3, thereby canceling the operation feedback function. Conversely, the sliding block 601 is pushed in the opposite direction to cancel the limitation of the push block 602 on the limiting block 403 at the end of the connecting rod 4. Since the connecting rod 4 always maintains a restoring force towards the surface of the guide rail 3, the feedback insert 5 at the end of the connecting rod 4 reattaches to the surface of the guide rail 3, so as to provide feedback when the guide rail 3 moves subsequently, thereby starting the operation feedback function. The operation is more convenient, and the operation requirements under different conditions are met.

[0055] In some other embodiments, referring to Figure 3 and Figure 4 , the bottom of the push block 602 includes a first bottom surface 6021 and a first inclined surface 6022, the top of the limiting block 403 is provided with a first top surface 4031, the first top surface 4031 is provided with a second inclined surface 4032 at one end close to the first inclined surface 6022. When the sliding block 601 slides to drive the push block 602 to move, the push block 602 extrudes the second inclined surface 4032 through the first inclined surface 6022 to push the limiting block 403, and drives the connecting rod 4 to rotate through the limiting block 403. When the sliding block 601 is pushed so that the first bottom surface 6021 at the bottom of the push block 602 is attached to the first top surface 4031 at the top of the limiting block 403, the connecting rod 4 is locked and the feedback insert 5 at the end of the connecting rod 4 is separated from the corresponding groove 301, so as to cancel the operation feedback when the operation part 2 operates.

[0056] In the embodiment, since the bottom of the push block 602 comprises the first bottom surface 6021 and the first inclined surface 6022 connected together, the top of the limiting block 403 comprises the first top surface 4031 and the second inclined surface 4032, and the second inclined surface 4032 is opposite to the first inclined surface 6022, in the normal state, the first inclined surface 6022 of the push block 602 is in the state of separation or critical contact with the second inclined surface 4032 of the limiting block 403, at this time, no force is applied between the first inclined surface 6022 of the push block 602 and the second inclined surface 4032 of the limiting block 403, and the feedback embedding piece 5 at the end of the connecting rod 4 is always tightly fitted with the surface of the guide rail 3 under the action of the reset force of the connecting rod 4, so as to maintain the operation feedback function. When it is needed to close the operation feedback function, the slider 601 is pushed along the sliding groove 103 to move in the first direction X, so that the first inclined surface 6022 of the push block 602 is pressed against the second inclined surface 4032 of the limiting block 403, and as the slider 601 is continuously pushed, the force of the first inclined surface 6022 of the push block 602 on the second inclined surface 4032 of the limiting block 403 is increased, until it is greater than the reset force of the connecting rod 4, so that the connecting rod 4 starts to move away from the surface of the guide rail 3, so that the feedback embedding piece 5 at the end of the connecting rod 4 is separated from the surface of the guide rail 3, and then the first bottom surface 6021 at the bottom of the push block 602 is continuously pushed to slide to be flush with the first top surface 4031 of the limiting block 403, so that the self-locking function of the limiting block 403 is realized by the push block 602, the limiting block 403 is kept in the current position to realize self-locking, so that the entire connecting rod 4 and the feedback embedding piece 5 are kept separated from the guide rail 3, and the operation feedback function is cancelled. Conversely, the slider 601 is pushed in the opposite direction of the first direction X, so that the first bottom surface 6021 of the push block 602 is separated from the first top surface 4031 of the limiting block 403, so that the limitation of the push block 602 on the limiting block 403 is cancelled, and the connecting rod 4 is reset under the action of the reset force of the connecting rod 4, so that the feedback embedding piece 5 at the end of the connecting rod 4 is tightly fitted with the surface of the guide rail 3 again, so as to open the operation feedback function, so as to adapt to different operation environments.

[0057] In some embodiments, the first inclined surface 6022 of the push block 602 is opposite to the second inclined surface 4032 of the limiting block 403. Figure 7 When the push block 602 is pushed to make the first inclined surface 6022 contact with the second inclined surface 4032, the acute angle S formed between the first inclined surface 6022 and the first top surface 4031 is at least greater than 18°, so as to ensure that the push block 602 has good pushing effect when the first inclined surface 6022 of the push block 602 contacts with the second inclined surface 4032 of the limiting block 403, so as to drive the limiting block 403 to rotate by the pushing of the push block 602.

[0058] Further, the sliding groove 103 is a self-locking sliding groove, and the sliding block 601 can be fixed at any position in the sliding groove 103.

[0059] It should be noted that, since the sliding groove 103 is a self-locking groove with a self-locking function, the sliding block 601 can be fixed at any position in the sliding groove 103, effectively resisting external vibration interference, ensuring that the sliding block 601 can be stable after each movement in the sliding groove 103, and facilitating the operation of the operator.

[0060] For example, the self-locking sliding groove is a sliding groove structure realized by friction, and self-locking can be realized when the combined slope is less than the self-locking angle. Since the rear combined part of the push block 602 is a plane, the push block 602 can only slide under external intervention, thereby realizing the self-locking function of the sliding groove 103 and ensuring that the sliding block 601 can be fixed at any position in the sliding groove 103.

[0061] It should be noted that the self-locking sliding groove in the present scheme can also realize self-locking by other structures, such as ratchet pawl or marble card point structure, and the present scheme does not particularly limit this, which will not be described here.

[0062] The present application also discloses a feedback adjusting device, which is applied to the operation feedback device or the feedback switch device, and comprises an adjusting knob assembly 7 installed at the end of the connecting rod 4. Figure 2 And Figure 5 The feedback adjusting device comprises an adjusting knob assembly 7 installed at the end of the connecting rod 4, which is arranged above the feedback embedding part 5 and is used to adjust the extrusion force between the feedback embedding part 5 and the guide rail 3, so as to adjust the scale feeling when the operation part 2 operates feedback.

[0063] In the embodiment, in order to further adjust the scale feedback feeling of different intensities, the adjusting knob assembly 7 is arranged to adjust the tightness between the feedback embedding part 5 and the guide rail 3, so that the operator can reasonably adjust the tightness between the feedback embedding part 5 and the guide rail 3 according to the own demand after the operation feedback function is started, thereby adjusting the scale feeling of different intensities when the operation feedback is performed, so as to meet the use of different operators.

[0064] In some embodiments, the adjusting knob assembly 7 comprises a spring piece 701 installed at the end of the connecting rod 4 and above the feedback embedding part 5, a pressing block 702 is installed at the top end of the spring piece 701, a knob 703 is screw-connected to the top of the pressing block 702, the height of the pressing block 702 on the spring piece is adjusted by rotating the knob 703, thereby adjusting the pressure of the spring piece 701 on the feedback embedding part 5, so as to adjust the intensity of the feedback embedding part 5 when the scale feedback is performed.

[0065] Specifically, since the spring piece 701 is installed at the end of the connecting rod 4 above the feedback insert 5, the pressure block 702 is installed at the top of the spring piece 701, and the knob 703 is screw-installed at the top of the pressure block 702, by rotating the knob 703, the position of the knob 703 on the pressure block 702 is adjusted, when the knob 703 is rotated in the clockwise direction, the knob 703 is constantly moved to the bottom of the pressure block 702, that is, towards the spring piece 701, so as to compress the spring piece 701 by the pressure block 702, so that the pressure of the spring piece 701 on the entire feedback insert 5 is increased, so that the pressure between the feedback insert 5 and the surface of the guide rail 3 is increased, so that when the feedback insert 5 is embedded in the groove 301 on the surface of the guide rail 3 during the movement of the guide rail 3, the force is greater, and the feedback of the scale feeling is stronger; conversely, rotating the knob 703 in the counterclockwise direction, the knob is constantly moved to the top of the pressure block 702, that is, away from the spring piece 701, so as to reduce the pressure between the pressure block 702 and the spring piece 701, so that the pressure of the spring piece 701 on the feedback insert 5 is reduced, so that the pressure between the feedback insert 5 and the guide rail 3 is reduced, so that when the feedback insert 5 is embedded in the groove 301 on the surface of the guide rail 3 during the movement of the guide rail 3, the force is reduced, and the feedback of the scale feeling is reduced, so as to realize the adjustment of the scale feedback of different intensities, and effectively meet the requirements of different scale feedback.

[0066] Specifically, when rotating the knob 703 to adjust the compression amount of the spring piece 701 by the pressure block 702, the greater the compression amount of the spring piece 701, the stronger the feedback of the scale feeling of the feedback insert 5 when the guide rail 3 moves.

[0067] Further, with reference to Figure 5 , in order to ensure stability, the number of spring pieces 701 is at least two, and correspondingly, the connecting rod 4 is also correspondingly provided as at least two groups, so that the pressure block 702 can remain stable when applying pressure to the spring piece 701, and the situation that the spring piece 701 applies uneven force to the feedback insert 5 is avoided, ensuring that the feedback insert 5 is uniformly stressed when in contact with the guide rail 3, and providing more accurate feedback feeling during scale feedback.

[0068] The description of the flow or structure of each of the above figures has its own emphasis, and the parts not described in detail in a certain flow or structure can be referred to the related description of other flows or structures.

[0069] The above embodiments are only illustrative of the principles of the present application and its effects, and are not intended to limit the present application. Any modification or change made by any person skilled in the art without departing from the spirit and scope of the present application shall be covered by the claims of the present application.
