Technical Field

[0001] The utility model belongs to the field of instrument control, and in particular relates to an encoding device with adjustable damping. Background Art

[0002] An encoding device is a device that converts motion signals into electrical signals. The encoding devices on existing products usually use contact rotary encoders. However, contact rotary encoders have a sense of jerkiness when rotating, which affects the use of the product.

[0003] In addition, the control of instrument products may require the use of multiple encoders. If multiple single encoders are used, it is easy to cause structural redundancy and increase the structural complexity and product area of ​​the product. There are currently encoding devices that can realize the control of multiple quantities. The push switch is combined with a rotary encoder to realize the dual functions of the push switch and the rotary encoder. However, it has relatively more parts and components, and the assembly is complicated, and only one rotary encoder can be realized. Therefore, based on the control requirements of instrument products, there is a lack of encoding devices that can realize multiple rotary encoders at the same time. Summary of the invention

[0004] In order to solve the above problems in the prior art, the utility model proposes an encoding device with adjustable damping.

[0014] Preferably, the fixing assembly includes fixed limiting members that are limitedly matched with the rotating shafts and floatingly matched with the damping adjustment assembly.

[0015] Preferably, the fixed limiting members are tightly fitted with each other.

[0016] Preferably, the fixing component is provided with holes, and the damping adjustment component is adjusted based on the holes.

[0017] Preferably, the detection element in the encoding component detects the rotational motion signal of the rotating shaft based on the hole.

[0018] Preferably, the detection element adopts an optical tracking sensor.

[0019] The beneficial effects of the utility model are as follows: the present invention proposes an encoding device with adjustable damping, which solves the problem of a sense of frustration when the encoder rotates by constructing a damping adjustment component; the elastic member in the damping adjustment component floats and moves relative to the corresponding fixed member, and variable damping of the rotating shaft is provided based on the use requirements, so that the encoder moves more smoothly, and the use experience of the product is improved; and the structure of the encoder device is stabilized, and encoder movement damping is provided, so that the movements of each encoder do not affect each other; in addition, the wear-resistant gaskets at both ends of the elastic member are used to reduce the wear on the device during the deformation of the elastic member, thereby increasing the service life;

[0020] The superimposed design structure of the multi-encoder body allows multiple encoders to be stacked and used simultaneously without affecting each other, thus saving installation space and reducing the product volume of the encoder. This solves the single problem of the existing single encoder and the problem of the area occupied by multiple single encoders, thereby reducing the product area of ​​the encoder application.

[0021] The overall structure mostly adopts threaded connection and slot limit to construct the superposition structure of multiple encoder devices, which has a simple structure, convenient installation and stable structure, and solves the problems of complex superposition structure and cumbersome installation of existing multiple encoders; in addition, combined with the provided holes, the friction damping adjustment component can be adjusted and the sensor can be used based on the needs, and it is conducive to observing the status of the encoder device, which is better suitable for the long-term use of the encoder and convenient for maintenance and observation.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] During the use of the ultra-depth-of-field microscope, there is a need to manually control the up and down movement of the lens above the measuring platform. Due to the high precision of the ultra-depth-of-field microscope, the up and down movement of the lens requires coarse and fine adjustments of the distance, and thus multiple encoding devices are required to control the coarse and fine adjustments respectively. However, the setting of multiple encoders on the microscope causes redundancy and unsightly product structure. Therefore, a damping-adjustable encoding device is designed in this scheme. The superimposed design structure of multiple encoders allows multiple encoders to be stacked, and the use of multiple encoders is realized at the same time without affecting each other, saving installation space.

[0031] Furthermore, the present invention designs a damping-adjustable encoding device, including an encoding component, which detects the rotational motion signal of the rotating shaft in the encoding component; a damping adjustment component, which provides corresponding damping for the rotation of the rotating shaft based on the adjustment of the relative position with the rotating shaft; and a fixed component, which changes the relative distance between the damping adjustment component and the fixed component based on the adjustment of the relative position between the damping adjustment component and the rotating shaft, based on the limited fit of the rotating shaft and the floating fit of the damping adjustment component. The fixed component cooperates with the damping adjustment component to provide corresponding damping, that is, different damping is provided based on the different relative distances between the damping adjustment component and the fixed component. Example

[0032] In this embodiment, the encoding component includes an encoding body including a rotating shaft. Figure 1 As shown, the encoding assembly includes an encoding body including a rotating axis.

[0033] The encoding body adopts a non-contact encoding body, including a first rotating shaft 3, a detection element, and a first knob 1. The first knob 1 is connected to the first rotating shaft 3 based on a slot limit fit to control the rotation of the first rotating shaft 3, and then control the movement of the main lens of the super depth of field microscope based on the rotation signal of the first rotating shaft 3; the detection element adopts an optical tracking sensor 5 to detect the rotational motion signal of the first rotating shaft 3; in this embodiment, the optical tracking sensor 5 is set on a circuit board fixedly connected to the fixed chassis 9 in the fixed component, so as to detect the rotational motion of the position on the first rotating shaft 3 corresponding to the optical tracking sensor 5. The detection element adopts the optical tracking sensor 5 to further simplify the structure of the encoding device.

[0034] Furthermore, the fixed component adopts a fixed chassis 9 which is sleeved on the outside of the first rotating shaft 3, that is, the fixed limiter in this embodiment adopts the fixed chassis 9, which is limited based on the first rotating shaft 3 and is floatingly connected with the damping adjustment component; in this embodiment, the fixed chassis 9 is limited based on the extension part provided on the first rotating shaft 3; the fixed chassis 9 can be used to fix the encoding device on the product to be used on the one hand, and on the other hand, it is used to cooperate with the damping adjustment component to provide corresponding damping.

[0035] Furthermore, the damping adjustment assembly includes a pressing member 6 and an elastic member 7, and the fixed chassis 9 is based on the floating cooperation between the elastic member 7 and the pressing member 6, and based on the adjustment of the relative position between the pressing member 6 and the rotating shaft, the relative distance between the pressing member 6 and the fixed assembly is changed, and the deformation of the elastic member 7 between the pressing member 6 and the fixed assembly is changed. Different damping is provided based on different deformations of the elastic member 7.

[0036] like Figure 2 As shown, the damping adjustment component is sleeved on the outside of the first rotating shaft 3 and is movably connected to the first rotating shaft 3, so that the relative position between the damping adjustment component and the first rotating shaft 3 can be adjusted; specifically, the pressure piece 6 in the damping adjustment component is sleeved on the outside of the first rotating shaft 3 and is threadedly matched with the first rotating shaft 3, and the relative position between the damping adjustment component and the first rotating shaft 3 is adjusted based on the threaded match; in this embodiment, the pressure piece 6 adopts a pressing sleeve with an extension plate, and the elastic piece 7 is sleeved on the outside of the pressing sleeve and is arranged between the pressing sleeve extension plate and the fixed chassis 9, so that the fixed chassis 9 is floatingly matched with the elastic piece 7 and the pressure piece 6; the fixed assembly is connected with the damping adjustment assembly in a floating match based on the elastic piece 7.

[0037] In addition, in this embodiment, the elastic member 7 is a corrugated gasket. The damping adjustment assembly also includes two wear-resistant gaskets 8, which are respectively arranged at both ends of the elastic member 7 and contact the pressing member 6 and the fixed chassis 9 respectively. The gasket is made of wear-resistant material to reduce the wear of the device during the deformation of the elastic member 7 and increase the service life. In this embodiment, the gasket is a polytetrachloroethylene gasket.

[0038] Furthermore, the damping-adjustable encoding device designed in this embodiment has the following working principle and process:

[0039] Based on the threaded fit of the pressing member 6 and the first rotating shaft 3 in the damping adjustment assembly, the relative position between the pressing member 6 and the first rotating shaft 3 is adjusted, the relative distance between the extension plate of the pressing member 6 and the fixed chassis 9 is changed, the elastic member 7 is squeezed to deform the elastic member 7, and then the first rotating shaft 3 is provided with damping corresponding to the deformation of the elastic member 7. The damping provided by the damping adjustment assembly can be adjusted based on the force sensing requirement of the rotary encoder knob, that is, the relative position between the pressing member 6 and the first rotating shaft 3 is adjusted based on the force sensing requirement, and the relative distance between the extension plate of the pressing member 6 and the fixed chassis 9 is changed to meet the force sensing requirement of the rotary encoder knob. Then, when the first rotating shaft 3 is rotated by the first knob 1, based on the fixing of the first rotating shaft 3 and the pressing member 6 by threaded cooperation, the rotation of the first rotating shaft 3 drives the pressing member 6 to rotate. However, based on the relative distance between the extension plate of the pressing member 6 and the fixed chassis 9, the elastic member 7 is squeezed to deform the elastic member 7. The compression deformation of the elastic member 7 provides damping for the rotation of the pressing member 6, and then the corresponding rotation force is provided to rotate the first knob 1. On the one hand, the damping adjustment component provides encoder movement damping and stabilizes the structure of the encoder device; on the other hand, it makes the encoder movement smoother and improves the user experience of the product. Example

[0040] In this embodiment, the encoding assembly includes two encoding bodies including a rotating shaft. Figure 3 As shown, the encoding assembly includes two encoding bodies including rotating shafts, namely the first encoding body and the second encoding body; each encoding body is nested in sequence. Specifically, the rotating shafts in each encoding body are nested in sequence, and the second rotating shaft 4 is sleeved on the outside of the first rotating shaft 3.

[0041] The first encoding body includes a first rotating shaft 3, a detection element, and a first knob 1. The first knob 1 is connected to the first rotating shaft 3 based on the card slot limit fit, thereby controlling the rotation of the first rotating shaft 3, and controlling the moving distance of the main lens of the super-depth microscope based on the rotation signal of the first rotating shaft 3. The second encoding body includes a second rotating shaft 4, a detection element, and a second knob 2. The second knob 2 is connected to the second rotating shaft 4 based on the card slot limit fit, thereby controlling the rotation of the second rotating shaft 4, and controlling the moving distance of the main lens of the super-depth microscope based on the rotation signal of the second rotating shaft 4. In this embodiment, the first encoding body and the second encoding body can respectively control the coarse adjustment and fine adjustment of the lens movement position in the super-depth microscope in combination with the system setting; the detection elements included in the first encoding body and the second encoding body both use an optical tracking sensor 5 to detect the rotation motion signal of the rotating shaft; in this embodiment, the optical tracking sensor 5 is set on a circuit board fixedly connected to the fixed chassis 9 in the fixed assembly, and the two sensors are arranged on the circuit board in a back-to-back layout, thereby detecting the rotation motion of the position corresponding to the optical tracking sensor 5 on the rotating shaft. The two sensors do not affect each other, thereby achieving relatively independent operation of the two encoding bodies.

[0042] The fixing assembly includes fixed stoppers that are matched with the rotating shafts and are matched with the damping adjustment assembly in a floating manner, and the fixed stoppers are relatively tightly matched with each other; specifically, Figure 4 As shown, the fixed limiting parts included in the fixing member 9 of this embodiment are respectively a fixed chassis 9 which is limitedly matched with the first rotating shaft 3 and floated with the damping adjustment component, and a corresponding support member 10 which is limitedly matched with the first rotating shaft 3 and floated with the damping adjustment component; the support member 10 is fixed on the fixed chassis 9.

[0043] Furthermore, in this embodiment, the fixed component is sleeved on the outside of the first rotating shaft 3, the fixed chassis 9 in the fixed component is limited and matched with the first rotating shaft 3, and the support member 10 is fixed on the fixed chassis 9 and sleeved on the outside of the first rotating shaft 3 and supported and limited and matched with the second rotating shaft 4 sleeved on the outside of the first rotating shaft 3; the first rotating shaft 3 and the second rotating shaft 4 do not contact each other or rotate relatively smoothly based on the support and limit of the fixed member 9 assembly.

[0044] Further, each of the rotating shafts is provided with a corresponding damping adjustment assembly, and each damping adjustment assembly includes a pressing member 6 and an elastic member 7. Based on the adjustment of the relative position between the pressing member 6 and the corresponding rotating shaft, the relative distance between the pressing member 6 and the corresponding fixed assembly is changed, and the deformation of the elastic member 7 between the pressing member 6 and the corresponding fixed assembly is changed. Specifically, the pressing member 6 in the damping adjustment assembly corresponding to the first rotating shaft 3 is sleeved on the outside of the first rotating shaft 3 and threadedly matched with the first rotating shaft 3. Based on the threaded matching, the relative position between the damping adjustment assembly and the first rotating shaft 3 is adjusted. The pressing member 6 corresponding to the first rotating shaft 3 adopts a pressing sleeve provided with an extension plate. The elastic member 7 is sleeved on the outside of the pressing sleeve and is arranged between the pressing sleeve extension plate and the fixed chassis 9, so that the fixed chassis 9 is floatingly matched based on the elastic member 7 and the pressing member 6. Based on the adjustment of the relative position between the pressing member 6 and the first rotating shaft 3, the relative distance between the pressing member 6 and the fixed chassis 9 is changed, and the deformation of the elastic member 7 between the pressing member 6 and the fixed chassis 9 is changed to provide corresponding damping.

[0045] The pressure piece 6 in the damping adjustment assembly corresponding to the second rotating shaft 4 is sleeved on the outside of the second rotating shaft 4 and threadedly matched with the second rotating shaft 4. The relative position between the damping adjustment assembly and the second rotating shaft 4 is adjusted based on the threaded matching. The pressure piece 6 corresponding to the second rotating shaft 4 adopts a pressing sleeve provided with an extension plate. The elastic piece 7 is sleeved on the outside of the second rotating shaft 4 and is arranged between the pressing sleeve extension plate and the inward extension plate provided on the support member 10, so that the support member 10 is based on the floating matching of the elastic piece 7 and the pressure piece 6. Based on the adjustment of the relative position between the pressure piece 6 and the second rotating shaft 4, the relative distance between the pressure piece 6 and the support member 10 is changed, and the deformation of the elastic piece 7 between the pressure piece 6 and the support member 10 is changed to provide corresponding damping.

[0046] In addition, if Figure 5 As shown, the side of the support member 10 is provided with holes, and the damping adjustment component corresponding to the second rotating shaft 4 is adjusted based on the holes, thereby providing variable damping based on demand for the rotation of the second rotating shaft 4; the side of the support member 10 can be provided with multiple holes, which are respectively used to adjust the damping adjustment component and for the detection element in the encoding component to detect the rotational motion signal of the rotating shaft based on the holes. Each damping adjustment component corresponding to each rotating shaft also includes two wear-resistant gaskets 8 respectively arranged at both ends of the elastic member 7, respectively contacting the pressing member 6 and the fixed limit member.

[0047] Furthermore, the damping-adjustable encoding device designed in this embodiment has the following working principle and usage process:

[0048] For the first encoding body, when the first rotating shaft 3 is rotated by the first knob 1, based on the threaded fit of the first rotating shaft 3 and the pressure piece 6, the rotation of the first rotating shaft 3 drives the pressure piece 6 to rotate. However, based on the threaded fit of the pressure piece 6 and the first rotating shaft 3, the relative distance between the pressure piece 6 and the fixed chassis 9 is changed, and then the elastic piece 7 is squeezed to deform the elastic piece 7. The compression deformation of the elastic piece 7 increases the damping provided to the rotation of the pressure piece 6, and then the first rotating shaft 3 provides damping. The corresponding rotational force can rotate the first knob 1.

[0049] For the second encoding body, when the second rotating shaft 4 is rotated by the second knob 2, based on the threaded fit of the second rotating shaft 4 and the pressure piece 6, the rotation of the second rotating shaft 4 drives the pressure piece 6 to rotate. However, based on the threaded fit of the pressure piece 6 and the second rotating shaft 4, the relative distance between the pressure piece 6 and the support piece 10 is changed, and then the elastic piece 7 is squeezed to deform the elastic piece 7. The compression deformation of the elastic piece 7 increases the damping provided to the rotation of the pressure piece 6, and then the second rotating shaft 4 provides damping. The corresponding rotational force can rotate the second knob 2.

[0050] Furthermore, the first encoding body and the second encoding body are nested and matched, and are respectively based on the limited matching and stability of the fixed chassis 9 and the support member 10, combined with the rotation damping of the rotating shaft provided by the damping adjustment components corresponding to each encoding body, so that the first encoding body and the second encoding body work relatively independently without affecting each other.

[0051] When using the ultra-depth-of-field microscope, there is a need to manually control the up and down movement of the lens above the measuring platform. The first encoding body and the second encoding body can respectively control the coarse and fine adjustment of the lens movement position in the ultra-depth-of-field microscope in combination with the system settings. Example

[0052] The damping adjustment component includes a pressing member 6 and an elastic member 7. Based on the adjustment of the relative position between the pressing member 6 and the rotating shaft, the relative distance between the pressing member 6 and the fixed component is changed, and the deformation of the elastic member 7 between the pressing member 6 and the fixed component is changed, so that the deformation of the elastic member 7 provides corresponding damping.

[0053] like Figure 6As shown, in this embodiment, the pressing member 6 is sleeved on the outside of the rotating shaft and is movably connected to the rotating shaft, and the relative position between the pressing member 6 and the rotating shaft is adjusted based on the movable connection; specifically, the pressing member 6 adopts an element with a thread on the inner wall that cooperates with the thread on the outer side of the rotating shaft. An element with a thread on the inner wall, such as a nut, can be adopted, which is sleeved on the outside of the rotating shaft and cooperates with the thread of the rotating shaft to adjust the relative position between the pressing member 6 and the rotating shaft, thereby changing the relative distance between the pressing member 6 and the fixed component, squeezing the elastic member 7 to deform the elastic member 7, and then providing damping corresponding to the deformation of the elastic member 7 in response to the rotation of the rotating shaft. Example

[0054] Based on an encoding device with adjustable damping in the first embodiment, the elastic member 7 includes one or more types of elastic members 7, and elastic members 7 such as corrugated gaskets, springs or disc springs may be used.

[0055] The present invention designs an encoding device with adjustable damping. By constructing a damping adjustment component, the problem of a sense of frustration when the encoder rotates is solved. The elastic member in the damping adjustment component floats and moves relative to the corresponding fixed member, and variable damping of the rotation of the rotating shaft is provided based on the use requirements, so that the encoder moves more smoothly, and the use experience of the product is improved. In addition, the structure of the encoder device is stabilized, and encoder movement damping is provided, so that the movements of each encoder do not affect each other. In addition, the wear-resistant gaskets at both ends of the elastic member are used to reduce the wear of the device during the deformation of the elastic member, thereby increasing the service life.

[0056] The superimposed design structure of the multi-encoder body allows multiple encoders to be stacked and used simultaneously without affecting each other, thus saving installation space and reducing the product volume of the encoder. This solves the single problem of the existing single encoder and the problem of the area occupied by multiple single encoders, thereby reducing the product area of ​​the encoder application.

[0057] The overall structure mostly adopts threaded connection and slot limit to construct the superposition structure of multiple encoder devices, which has a simple structure, convenient installation and stable structure, and solves the problems of complex superposition structure and cumbersome installation of existing multiple encoders; in addition, combined with the provided holes, the friction damping adjustment component can be adjusted and the sensor can be used based on the needs, and it is conducive to observing the status of the encoder device, which is better suitable for the long-term use of the encoder and convenient for maintenance and observation.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
