[0002] As a component of a stopping structure, a stopper is required to precisely and reliably limit the movement of parts in a mechanical system, keeping them stationary in a preset position. In precision machinery such as optical instruments and command instruments, it is typically installed in a fixed position to restrict the movement of the instrument in a certain degree of freedom, thereby achieving the effect of stopping the instrument.

[0003] With technological advancements and increasingly stringent requirements for instruments and equipment, the design constraints of stoppers are becoming more and more stringent. Stoppers required in photoelectric turntables typically need to restrict azimuth and pitch movements while ensuring sufficiently small size, high reliability, and, considering manufacturing difficulties, minimalist and cost-effective structural design. This invention comprehensively considers these factors and designs a bidirectional manual integrated stopper suitable for photoelectric turntables.

[0004] Therefore, how to provide a two-way manual integrated stop that can overcome the shortcomings of existing technologies, has a simple, compact and reliable structure, flexible control, and can independently adjust the azimuth and pitch locking states under a single drive source, while integrating both electric and manual drive modes, has become an urgent technical problem to be solved.

[0013] Furthermore, the handle 201 is directly fixed to the end of the output shaft of the motor 203 by fastener 202, so that the output shaft is directly driven to rotate when the handle 201 is manually operated.

[0014] Furthermore, the housing assembly 1 includes a base plate 102, a cover plate 101, and a connector 103; The base plate 102 provides the main mounting surface for the drive assembly 2, the azimuth stop actuator 3, and the pitch stop actuator 4; the cover plate 101 covers the base plate 102 and has openings through which the operating components of the azimuth stop actuator 3 and the pitch stop actuator 4 can pass.

[0015] Furthermore, in any of the above-mentioned bidirectional manual integrated stoppers, motor 203 is a hybrid stepper motor.

[0016] The beneficial effects of this invention are as follows: As can be seen from the above scheme, the embodiments of the present invention provide a bidirectional manual integrated stop, wherein the housing assembly 1 constitutes the mounting base of the stop; the drive assembly 2 is mounted on the housing assembly 1; the drive assembly 2 includes a manually operable handle 201, a motor 203, a motion conversion mechanism that converts rotational motion into linear motion, and a locking lever 205 driven by the motion conversion mechanism; the handle 201 is operably connected to the output shaft of the motor 203, so that the locking lever 205 can selectively generate axial linear motion by manually driving the handle 201 or electrically driving the motor 203; the directional stop actuator 3 is mounted on the housing assembly 1 and includes a directional pin 307 and a first transmission connection mechanism; the first transmission connection mechanism is used for In the engaged state, the axial linear motion of the locking lever 205 is transmitted and converted into the extension or retraction motion of the azimuth pin 307.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] The purpose of this invention is to provide a novel bidirectional manual integrated stop to meet the stopping requirements of photoelectric turntables. This stop has the function of independent azimuth and pitch locking, and has both manual and electric locking control modes. The electric mode is more intelligent, while the manual mode is more reliable. This stop achieves small size, simple structure, and high reliability, meeting the bidirectional stopping requirements of photoelectric turntables.

[0020] like Figures 1 to 7 As shown, Figure 1 This is a schematic diagram of a bidirectional manual integrated stopper according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the housing structure of a bidirectional manual integrated stopper according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the drive assembly structure of a bidirectional manual integrated stopper according to an embodiment of the present invention; Figure 4 This is a schematic diagram of the shaft system structure of a bidirectional manual integrated stopper according to an embodiment of the present invention; Figure 5 This is a schematic diagram of the orientation stop structure of a bidirectional manual integrated stopper according to an embodiment of the present invention; Figure 6 This is a schematic diagram of the pitch stop structure of a bidirectional manual integrated stop according to an embodiment of the present invention; Figure 7 This is a schematic diagram of the stop locking mechanism of a bidirectional manual integrated stopper according to an embodiment of the present invention.

[0021] The figure shows a two-way manual integrated stop, including: a housing assembly 1, a drive assembly 2, an azimuth stop actuator 3, and a pitch stop actuator 4; Housing assembly 1 constitutes the mounting base of the stopper; Drive assembly 2 is mounted on housing assembly 1; drive assembly 2 includes: a manually operable handle 201, a motor 203, a motion conversion mechanism that converts rotary motion into linear motion, and a locking lever 205 driven by the motion conversion mechanism; wherein, the handle 201 is operatively connected to the output shaft of the motor 203, so that the locking lever 205 can selectively generate axial linear motion by manually driving the handle 201 or electrically driving the motor 203; The directional stop actuator 3 is mounted on the housing assembly 1 and includes an directional pin 307 and a first transmission connection mechanism; the first transmission connection mechanism is used to transmit the axial linear motion of the locking rod 205 and convert it into the extension or retraction motion of the directional pin 307 when in the engaged state. The pitch stop actuator 4 is mounted on the housing assembly 1 and includes a pitch pin 407 and a second transmission connection mechanism; the second transmission connection mechanism is used to transmit the axial linear motion of the locking rod 205 and convert it into the extension or retraction motion of the pitch pin 407 when in the engaged state. The first and second transmission connection mechanisms each have independently operable engagement and disengagement states. By independently controlling the engagement state of the first and second transmission connection mechanisms, the stop can be configured to three working modes: simultaneous azimuth and pitch locking, azimuth locking only, or pitch locking only.

[0022] In this embodiment of the invention, a bidirectional manual integrated stopper, through the coordinated design of a "single drive group" and a "bidirectional independently selectable transmission connection mechanism," fundamentally solves the problems of structural redundancy and inflexible control in traditional bidirectional stoppers. Compared with existing technologies using two independent drive systems, this invention greatly simplifies the structure, reduces cost and size, and achieves miniaturization. Simultaneously, the configurability of three operating modes (full lock, azimuth single lock, and pitch single lock) provides unprecedented operational flexibility, meeting the precise control requirements under complex working conditions—a creative function not found in existing integrated stoppers.

[0023] The handle and motor shaft are fixed together by a locking screw. Manually rotating the handle drives the stepper motor shaft to rotate, causing the locking shaft to move axially along with the locking lever. This movement is then transmitted through the azimuth and pitch levers, resulting in the axial movement of the azimuth and pitch pins, achieving manual locking. Simultaneously, the stepper motor shaft can be electrically controlled to achieve electric locking. Electric locking is convenient and intelligent, while manual locking is safe and reliable. The axial movement of the locking lever, through the transmission and decomposition of the azimuth and pitch levers, results in the axial movement of the azimuth and pitch pins, achieving bidirectional azimuth and pitch locking. Rotating the azimuth pin controls the connection between the azimuth pin and the locking lever, creating an azimuth drive switch. Similarly, rotating the pitch pin controls the relative position of the pitch pin and the locking lever, creating a pitch drive switch. This allows for three locking states under motor shaft drive: bidirectional azimuth and pitch locking, azimuth-only locking, and pitch-only locking, ensuring controllable bidirectional azimuth and pitch locking of the stop. The two-way manual integrated stopper is driven by a motor and achieves bidirectional stopping in both azimuth and pitch through the lever principle. The entire stopper has a simple and reliable structure, realizing the miniaturization and intelligence of the two-way stopper.

[0024] In one embodiment of the present invention, the motion conversion mechanism in the drive group 2 includes a stop shaft 206 that rotates synchronously with the output shaft of the motor 203 or the handle 201, and the stop shaft 206 is provided with an axial threaded section or a slanted groove. The locking rod 205 is provided with a transmission part that engages with the threaded section or the inclined groove, so that the rotation of the stop shaft 206 drives the locking rod 205 to move axially in a linear motion.

[0025] The method of converting rotary motion into linear motion offers advantages such as precise transmission, good self-locking (especially when using threads), and simple and reliable structure. Compared to possible linkage or cam mechanisms, this solution makes it easier to control axial travel accuracy and provides greater axial thrust, which helps ensure a secure lock.

[0026] In another embodiment of the present invention, the drive group 2 further includes a limiting mechanism for limiting the axial travel of the locking rod 205; The limiting mechanism includes a limiting block 207 fixedly mounted on the stop shaft 206 and a limiting groove mounted on the housing assembly 1 or the motor mounting bracket. The limiting block 207 moves within the limiting groove and limits the movement limit position of the locking rod 205 by abutting against the end of the limiting groove.

[0027] In this embodiment of the invention, a limiting mechanism is added. Through mechanical hard limiting, the travel distance of the locking lever is precisely defined, thereby indirectly controlling the extension length of the azimuth and pitch pins. This prevents damage to the mechanism due to overdrive (such as excessive lever bending or spring compression), ensures the reliability and consistency of the locking action, and improves the service life and safety of the entire device.

[0028] In another embodiment of the present invention, the first transmission connection mechanism in the orientation stop actuator 3 includes: The directional lever 304 is rotatably supported on the housing assembly 1, forming a fulcrum; A first detachable connecting assembly is used to input the linear motion of the locking lever 205 to the first end of the azimuth lever 304; The orientation motion conversion component is connected to the second end of the orientation lever 304 and is used to convert the swing of the orientation lever 304 into the linear motion of the orientation pin 307. The second transmission connection mechanism in the pitch stop actuator 4 includes: The pitch lever 404 is rotatably supported on the housing assembly 1, forming a fulcrum; The second detachable connection assembly is used to input the linear motion of the locking lever 205 to the first end of the pitch lever 404; The pitch motion conversion component is connected to the second end of the pitch lever 404 and is used to convert the swing of the pitch lever 404 into the linear motion of the pitch pin 407.

[0029] In this embodiment of the invention, the small linear displacement of the locking lever is converted into a larger linear displacement of the pin end through the proportional relationship of the lever arms. This ensures sufficient locking stroke while allowing for a more compact design of the drive mechanism (motor and handle). Specifically, the axial movement of the locking lever is cleverly converted into the radial (or vertical) movement of the pin, resulting in a more rational overall layout and facilitating the arrangement of two orthogonal locking mechanisms for orientation and pitch within a limited space. This offers greater space utilization advantages compared to direct transmission methods such as using unidirectional push rods.

[0030] In another embodiment of the present invention, the first separable connecting assembly includes an axially movable and circumferentially rotatable azimuth pin 301 and a first biasing element 302. The azimuth pin 301 has a first connecting end, and the locking rod 205 is provided with a first connecting part that matches the first connecting end; by pressing and rotating the azimuth pin 301, the first connecting end and the first connecting part can be selectively engaged or disengaged, and when disengaged, they are driven to reset by the first biasing element 302. The second detachable connection assembly has the same structure as the first detachable connection assembly.

[0031] Users can easily "open" or "close" the transmission path with simple pressing and rotating actions, providing a user-friendly interface. The pin ejection (separation) and pressing (engagement) provide clear visual and tactile feedback. The mechanical engagement structure has no complex circuitry, strong anti-interference capabilities, and spring return ensures the transmission path is completely disconnected in the non-engaged state, preventing malfunctions. Compared to solutions like electromagnetic clutches or electronically controlled valves, this is lower in cost, more environmentally adaptable, and particularly suitable as a manual operation interface.

[0032] In another embodiment of the present invention, the orientation motion conversion component includes an orientation linear guide rail 305 fixed on the housing assembly 1 and an orientation slider 306 slidably disposed on the orientation linear guide rail 305. The second end of the azimuth slider 306 is connected to the second end of the azimuth lever 304 through a first kinematic pair, and the azimuth pin 307 is fixedly installed on the azimuth slider 306; the pitch motion conversion assembly includes a pitch linear guide rail 405 fixed on the housing assembly 1 and a pitch slider 406 slidably disposed on the pitch linear guide rail 405; the second end of the pitch slider 406 is connected to the second end of the pitch lever 404 through a second kinematic pair, and the pitch pin 407 is fixedly installed on the pitch slider 406.

[0033] The combination of a linear guide rail and a slider, along with a cylindrical pin and a slotted groove, offers significant advantages: the linear guide rail ensures precise and smooth slider movement with low friction, improving the smoothness and positioning accuracy of the locking action; the guide rail can withstand radial forces from the pin during locking, protecting the lever mechanism from lateral forces. This is a classic oscillating-linear motion conversion pair, simple in structure, easy to manufacture, and possesses a certain degree of motion compensation capability, adapting to minor alignment errors during installation and operation, thus improving the mechanism's fault tolerance and reliability.

[0034] In another embodiment of the present invention, both the first kinematic pair and the second kinematic pair are mating structures of a cylindrical pin and a waist-shaped groove, wherein the cylindrical pin is disposed on the azimuth slider 306 or the pitch slider 406, and the waist-shaped groove is opened at the second end of the corresponding azimuth lever 304 or the pitch lever 404.

[0035] In another embodiment of the present invention, the handle 201 is directly fixed to the end of the output shaft of the motor 203 by fastener 202, so that the output shaft is directly driven to rotate when the handle 201 is manually operated.

[0036] In another embodiment of the present invention, the housing assembly 1 includes a base plate 102, a cover plate 101, and a connector 103; The base plate 102 provides the main mounting surface for the drive assembly 2, the azimuth stop actuator 3, and the pitch stop actuator 4; the cover plate 101 covers the base plate 102 and has openings through which the operating components of the azimuth stop actuator 3 and the pitch stop actuator 4 can pass.

[0037] In this embodiment of the invention, all core mechanisms can be first installed on the base plate for calibration, and then finally sealed with a cover, improving production efficiency and product quality. The opening design on the cover plate is specifically for the operation of the pins, resulting in a neat overall appearance while protecting the internal mechanisms.

[0038] In another embodiment of the present invention, in a bidirectional manual integrated stop according to any of the above claims, the motor 203 is a hybrid stepper motor.

[0039] The hybrid stepper motor can provide driving force to drive the locking lever to move axially, control the movement of the azimuth stop group and the pitch stop group pins, and realize the electric locking of the stop.

[0040] The manually rotated handle provides driving force, which drives the locking lever to move axially, controls the movement of the azimuth stop group and the pitch stop group pins, and realizes manual locking of the stop.

[0041] In one embodiment of the present invention, a novel bidirectional manual integrated stop integrates both manual and electric drive modes, simplifies the motion transmission method, and incorporates a locking direction switch to complete a controllable manual integrated bidirectional stop. The structural composition is as follows: Figure 1 As shown, the overall structure consists of a housing assembly 1, a drive assembly 2, an azimuth stop assembly 3, and a pitch stop assembly, which respectively realize the functions of installation positioning, driving, and motion transmission, and combine to form a controllable manual integrated stop function. It features small size and high reliability.

[0042] Figure 2 In this assembly, the housing consists of a cover plate 101, a mounting base plate 102, and double-through studs 103. The cover plate and the mounting base plate are connected as a whole by double-through studs and can be fastened with countersunk screws. The top and back of the cover plate are designed with U-shaped grooves to provide mounting interfaces for the azimuth and pitch locking switches. The base plate is designed with relevant mounting surfaces and reserved threaded holes to provide the installation and positioning requirements for the drive group, azimuth stop group, and pitch stop group.

[0043] Driver groups such as Figure 3 As shown, both manual and electric control modes are possible. The handle 201 is fixed to the shaft of the hybrid stepper motor 203 via a stop screw 202, rotating with the motor shaft. The hybrid stepper motor is fixed to the mounting base plate via a motor adapter bracket 204. Both manually rotating the handle and electrically controlling the motor will rotate the motor shaft, transmitting the motion to the axial movement of the stop shaft 206. The locking rod 205 is fixed to the stop shaft and moves axially with it. The drive assembly shaft system structure is as follows... Figure 4 As shown, the limit block 207 is fixedly installed on the stop shaft and moves axially within the groove of the motor mounting bracket. The end face of the groove restricts the axial movement range of the stop shaft and the locking rod, thereby limiting the stop stroke of the stopper.

[0044] Figure 5 In this configuration, the drive unit drives the locking lever to move within the axial range of the stop shaft. The azimuth lever 304 is connected to the locking lever via the azimuth pin 301. The two ends of the azimuth lever shaft are circumferentially fitted by the chassis and the azimuth pin bracket 303, forming a rotating pair around the azimuth lever shaft. The axial movement of the locking lever, through the transmission of the azimuth lever, forms the circumferential movement of the azimuth lever around its shaft. The azimuth linear guide rail 305 is horizontally fixed to the mounting base plate, and the azimuth slider 306 is fixed on the azimuth linear guide rail for linear movement. The azimuth pin 307 is mounted on the end face of the azimuth slider, with a cylindrical pin at the bottom that inserts into the monocular groove of the azimuth lever. The circumferential movement of the azimuth lever around its shaft is converted into the linear movement of the azimuth slider, which in turn forms the axial movement of the azimuth pin.

[0045] The installation and fit of the directional pin with the locking rod and cover plate is as follows: Figure 7 As shown. The directional pin passes through the circumference of the cover plate and is elastically supported by the directional spring 302. The bottom of the directional pin has symmetrical limiting protrusions. When the directional pin is pressed and rotated at the appropriate position, the directional pin can be inserted into the mating groove of the locking rod through the notch of the locking rod. At this time, the directional pin and the locking rod are connected, and the axial movement of the locking rod can be transmitted to the axial movement of the directional pin. When the limiting protrusion of the directional pin is rotated to the notch of the locking rod, the directional pin will pop out of the locking rod under the elastic force of the directional spring. At this time, the axial movement of the locking rod will no longer be transmitted to the directional pin.

[0046] Figure 6 In this configuration, the drive unit drives the locking lever to move within the axial range of the stop shaft. The pitch lever 404 is connected to the locking lever via the pitch pin 404. Both ends of the pitch lever shaft are circumferentially engaged with the pitch pin bracket 403, forming a rotating pair of the pitch lever around the pitch lever shaft. The axial movement of the locking lever, through the transmission of the pitch lever, forms the circumferential movement of the pitch lever around the pitch lever shaft. The pitch linear guide rail 405 is vertically fixed on the mounting base plate, and the pitch slider 406 is fixed on the pitch linear guide rail for linear rolling. The pitch pin 407 is mounted on the end face of the pitch slider, with a cylindrical pin block on the front that is inserted into the monocular groove of the pitch lever. The circumferential movement of the pitch lever around the pitch lever shaft is converted into the linear movement of the pitch slider, which in turn forms the axial movement of the pitch pin.

[0047] The installation and engagement of the pitch pin with the locking lever and cover plate are the same as those with the azimuth pin, and will not be repeated here. Rotating and pressing the pitch pin to connect it to the locking lever will open the locking motion of the pitch pin shaft; rotating and popping the pitch pin to disconnect it from the locking lever will close the locking motion of the pitch pin shaft.

[0048] The technical solution of this invention can drive the stop shaft manually or electrically to control the azimuth and pitch pins, forming an azimuth and pitch stop switch. It can achieve three working modes: simultaneous azimuth and pitch stop, azimuth locked with pitch immobile, and azimuth immobile with pitch locked. The initial positions of both the azimuth and pitch pins are at the guide rail end face. The state when azimuth and pitch are simultaneously locked is as follows... Figure 7 As shown.

[0049] This invention provides a bidirectional manual integrated stop, wherein a housing assembly 1 constitutes the mounting base of the stop; a drive assembly 2 is mounted on the housing assembly 1; the drive assembly 2 includes a manually operable handle 201, a motor 203, a motion conversion mechanism that converts rotational motion into linear motion, and a locking lever 205 driven by the motion conversion mechanism; the handle 201 is operatively connected to the output shaft of the motor 203, such that the locking lever 205 can selectively generate axial linear motion by manually driving the handle 201 or electrically driving the motor 203; an azimuth stop actuator 3 is mounted on the housing assembly 1 and includes an azimuth pin 307 and a first transmission connection mechanism; the first transmission connection mechanism is used for engagement... In the engaged state, the axial linear motion of the locking lever 205 is transmitted and converted into the extension or retraction motion of the azimuth pin 307; the pitch stop actuator 4, mounted on the housing assembly 1, includes the pitch pin 407 and the second transmission connection mechanism; the second transmission connection mechanism is used to transmit the axial linear motion of the locking lever 205 and convert it into the extension or retraction motion of the pitch pin 407 in the engaged state; both the first transmission connection mechanism and the second transmission connection mechanism have independently operable engaged and disengaged states; by independently controlling the engaged state of the first transmission connection mechanism and the second transmission connection mechanism, the stop can be configured to three working modes: simultaneous azimuth and pitch locking, azimuth locking only, or pitch locking only.

[0050] The technical solution of this invention can overcome the shortcomings of the prior art. It has a simple, compact and reliable structure, flexible control, and can independently adjust the azimuth and pitch locking states under a single drive source. It also integrates electric and manual drive modes.

[0051] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
