Description

Technical Field

[0001] This invention relates to the field of optical equipment, and more particularly to a lifting device with a locking function. Background Technology

[0002] Optical cabins are used to house optical equipment integrated with lifting platforms. To minimize the impact of vibrations on the optical equipment during operation and transportation, a lifting device is required. Specifically, during operation, the lifting device raises the optical cabin and provides rigid support to the ground, ensuring reliable operation of the optical equipment. During transportation, the lifting device lowers the optical cabin to the support platform, and a vibration damping device is installed between the optical cabin and the support platform to isolate vibration interference and ensure transportation stability. However, the vibration damping capacity of the relevant lifting devices is relatively weak, resulting in a significant impact of external vibrations on the optical equipment. Summary of the Invention

[0003] This invention provides a lifting device with a locking function to solve the technical problem of how to improve vibration reduction capability, thereby reducing the impact of external vibration on optical equipment.

[0004] This invention provides a lifting device with a locking function, comprising: an optical cabin housing optical equipment; a lifting assembly, one end of which is fixedly connected to the optical cabin for driving the optical cabin to move vertically up and down; a support platform having a support surface; and a vibration damping device fixedly connected to the optical cabin and located between the optical cabin and the support platform. The vibration damping device has a first locking structure, and the support platform has a second locking structure. When the support platform is in contact with the vibration damping device, the first locking structure and the second locking structure can switch between a locked state and an unlocked state. In the locked state, a locking force is formed between the first locking structure and the second locking structure, which restricts the movement of the optical cabin away from the support platform. In the unlocked state, the locking force is removed.

[0005] In some embodiments, the first locking structure and the second locking structure are capable of relative movement in a first direction to switch between the locked state and the unlocked state, wherein the first direction is not parallel to the vertical direction.

[0006] In some embodiments, the first locking structure includes a locking hole whose depth direction is parallel to the first direction; the second locking structure includes a locking pin slidably connected to the support platform and capable of sliding between a first position and a second position along the first direction; at the first position, the locking pin is capable of extending into the locking hole to form the locked state; at the second position, the locking pin is located outside the locking hole to form the unlocked state.

[0007] In some embodiments, the second locking structure includes a locking opening formed by the vertical indentation of the support surface. The inner wall of the locking opening has an arcuate groove and a clearance groove. The arcuate groove extends along a first direction, and the clearance groove is formed by the vertical indentation of the inner wall of the locking hole along a second direction. The second direction is radially parallel to the arcuate groove, and the clearance groove extends vertically from the support surface to the arcuate groove. The first locking structure includes a locking post protruding vertically from the vibration damping device. The outer surface of the locking post has a locking boss protruding along a third direction from the outer surface of the locking post. The locking post is rotatably connected to the vibration damping device, and the locking boss is rotatable between a third position and a fourth position along the first direction. At the third position, the locking boss is located within the arcuate groove and the second direction is not parallel to the second direction, forming the locked state. At the fourth position, the locking post is located within the arcuate groove and the third direction is parallel to the second direction, forming the unlocked state.

[0008] In some embodiments, the relative vertical movement of the first locking structure and the second locking structure enables the first locking structure and the second locking structure to switch between the locked state and the unlocked state; wherein, when the vertically upward force applied by the lifting assembly to the first locking structure is greater than the unlocking threshold, the first locking structure and the second locking structure switch from the locked state to the unlocked state.

[0009] In some embodiments, the first locking structure includes a first latching structure, and the second locking structure includes a second latching structure; in the vertical direction, the first latching structure moves downward to engage with the second latching structure, and the second latching structure moves upward to separate the first latching structure from the second latching structure.

[0010] In some embodiments, the first locking structure includes a friction post that protrudes vertically from the vibration damping device; the second locking structure includes a friction hole with a diaphragm spring inside, the two ends of the diaphragm spring being fixed to the inner wall of the friction hole, and the middle portion of the diaphragm spring protruding into the friction hole. When the friction post is located inside the friction hole, the diaphragm spring can abut against the friction post.

[0011] In some embodiments, the first locking structure includes a first magnetic structure fixed to the bottom of the vibration damping device, and the second locking structure includes a second magnetic structure fixed to the support surface, wherein the first magnetic structure and the second magnetic structure are capable of engaging.

[0012] In some embodiments, there are multiple vibration damping devices, which are spaced apart, and the number of the second locking structures is the same as the number of vibration damping devices.

[0013] In some embodiments, the bottom of the vibration damping device has a guide post, and the support surface has a guide hole; in a cross section perpendicular to the vertical direction, the cross-sectional area of ​​the guide post decreases along the direction in which the guide post extends, and / or, in a cross section perpendicular to the vertical direction, the cross-sectional area of ​​the guide hole decreases along the direction in which the guide hole is recessed.

[0014] In some embodiments, the lifting device further includes a lifting platform, which is housed within the optical cabin and fixedly connected to the optical cabin; the lifting platform is connected to the optical equipment and is used to drive the optical equipment to move vertically relative to the optical cabin.

[0015] In some embodiments, the lifting assembly includes: a ball screw connected to the optical cabin; a sleeve fitted over the ball screw; and a motor located on one side of the sleeve in an extension direction perpendicular to the sleeve, and the motor being connected to the ball screw via a transmission structure.

[0016] This invention provides a lifting device with a locking function. The lifting device includes: an optical cabin for accommodating optical equipment; a lifting assembly fixedly connected to the optical cabin to drive its lifting movement; a support platform with a support surface; and a vibration damping device fixedly connected to the optical cabin and located between the optical cabin and the support surface. When the optical equipment is needed, the lifting assembly raises the optical cabin; when the optical equipment needs to be transported, the lifting assembly lowers the optical cabin and brings the vibration damping device into contact with the support surface, thereby absorbing vibrations acting on the optical cabin. The vibration damping device has a first locking structure, and the support platform has a second locking structure. When the support platform and the vibration damping device are in contact, the first and second locking structures can switch between a locked state and an unlocked state. In the locked state, a locking force is formed between the first and second locking structures. In the unlocked state, the locking force is released. In other words, when the optical cabin needs to be transported, the lifting assembly brings the vibration damping device into contact with the support platform, and the first and second locking structures are locked. In this state, the movement of the optical cabin away from the support platform is transmitted to the vibration damping device by the first and second locking structures, causing the vibration damping device to be stretched and deformed. At the same time, when the optical cabin needs to be used, the first and second locking structures are controlled to switch from the locked state to the unlocked state, so that the locking force is removed, allowing the optical cabin to rise under the drive of the lifting assembly. That is, the vibration damping device can absorb vibration not only when the optical cabin is close to the support platform, but also when the optical cabin is far from the support platform, it can absorb vibration through the deformation caused by compression. This improves the vibration damping capability of the lifting device and reduces the impact of external vibration on the optical equipment. Meanwhile, by keeping the first and second locking structures in the unlocked state, the optical cabin still has the function of lifting. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0044] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0045] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0046] In the following specific embodiments, the lifting device with locking function can be used to carry any optical equipment, such as an optical radar, laser rangefinder, or optical theodolite. The lifting device with locking function can be fixed to any transport equipment; for example, the transport equipment can be a vehicle or a ship. The structure and function of the lifting device with locking function will be described below with reference to various embodiments.

[0047] In some embodiments, such as Figure 1 As shown, the lifting device 1 includes: an optical cabin 10, a lifting assembly 20, a support platform 30, and a vibration damping device 40. The optical cabin 10 has a receiving cavity in which the optical equipment is located, thereby protecting the optical equipment through the optical cabin 10. At the same time, the outer surface of the optical cabin 10 also provides installation space for other parts.

[0048] One end of the lifting assembly 20 is fixedly connected to the optical cabin 10 and is used to drive the optical cabin 10 to move up and down in the vertical direction. The lifting assembly 20 can be any structure capable of lifting and driving. For example, the lifting assembly 20 can be a linear cylinder to directly drive the optical cabin 10 to move up and down. For example, the lifting assembly 20 includes a drive motor and a transmission structure. The transmission structure is connected to the optical cabin 10 and is used to convert the rotational motion output by the drive motor into linear motion and drive the optical cabin 10 to move up and down in the vertical direction. For example, the transmission structure can be a circulating ball screw transmission structure.

[0049] The support platform 30 has a support surface 32. The vibration damping device 40 is fixedly connected to the optical cabin 10 and moves up and down together with the optical cabin 10. The vibration damping device 40 is located between the optical cabin 10 and the support surface 32. When the optical cabin 10 needs to be transported, the lifting component 20 is controlled to lower the optical cabin 10 until the vibration damping device 40 is pressed between the optical cabin 10 and the support surface 32. When external vibrations are transmitted to the optical cabin 10 through the support surface 32, the vibrations can be buffered and absorbed by the vibration damping device 40, thereby reducing the impact of vibrations on the optical cabin 10. Depending on the connection position between the lifting component 20 and the optical cabin 10, the connection method between the lifting component 20 and the support surface 32 varies. For example, when the lifting component 20 is fixed to the side of the optical cabin 10, the lifting component 20 can be directly fixed to the support member 31, so that the vibration damping device 40 can be pressed between the optical cabin 10 and the support surface 32. For example, when the lifting component 20 is fixed to the bottom surface of the optical cabin 10, in order to press the vibration damping device 40 between the optical cabin 10 and the support surface 32, the other end of the lifting component 20 is fixed to another mounting plane, and the mounting plane is lower than the support surface 32.

[0050] Meanwhile, the vibration damping device 40 has a first locking structure 41, and the support platform 30 has a second locking structure 31. When the support platform 30 is in contact with the vibration damping device 40, the first locking structure 41 and the second locking structure 31 can switch between a locked state and an unlocked state. When the first locking structure 41 and the second locking structure 31 are in the locked state, a locking force is formed between them. When the first locking structure 41 and the second locking structure 31 are in the unlocked state, this locking force is removed. This can be understood as follows: when the optical cabin 10 needs to be transported, the lifting assembly 20 brings the vibration damping device 40 into contact with the support platform 30, and the first locking structure 41 and the second locking structure 31 are locked. In this state, the optical cabin 1... The movement of the optical cabin 10 away from the support platform 30 is transmitted to the vibration damping device 40 by the first locking structure 41 and the second locking structure 31, thereby causing the vibration damping device 40 to be stretched and deformed. That is, the vibration damping device 40 can absorb vibration not only when the optical cabin 10 is close to the support platform 30, but also when the optical cabin 10 is away from the support platform 30, through the deformation caused by stretching. This improves the vibration damping capability of the lifting device 1 and reduces the impact of external vibration on the optical equipment. When the optical cabin needs to be used, the first locking structure 41 and the second locking structure 31 are controlled to switch from the locked state to the unlocked state to remove the locking force, so that the optical cabin 10 can rise under the drive of the lifting assembly 20.

[0051] It should be noted that when the optical container is in the transport state, the support platform 30, the vibration damping device 40, and the optical container 10 can be considered to form a vibration system. The external environment will excite this vibration system to vibrate. Those skilled in the art generally believe that this excitation is an impact load applied to the vibration system from the outside. If this impact load is directly transmitted from the support platform 30 to the optical container 10, it may cause damage to the optical equipment. Therefore, it is necessary to install a vibration damping device 40 between the support platform 30 and the optical container 10. Since the impact load is transmitted upward from the support platform 30 to the optical container 10, the deformation of the vibration damping device 40 is mainly in the form of compression. The compression deformation of the vibration damping device 40 has already... This is sufficient to meet the vibration reduction requirements under this excitation mode. At the same time, in order to facilitate the lifting of the optical cabin 10, those skilled in the art will not set any connecting structure between the vibration reduction device 40 and the support platform 30. However, the external environment may also excite the vibration system in the form of displacement. Specifically, when the external environment causes the vibration system to move back and forth in a large manner, due to the difference in inertia between the optical cabin 10 and the support platform 30, a large relative displacement will occur between the optical cabin 10 and the support platform 30. This excitation mode may occur when a vehicle falls from a high position to the road surface, or when a ship passes through high waves and falls to the water surface.

[0052] Under this excitation method, if no connection structure is provided between the vibration damping device 40 and the support platform 30, the optical cabin 10 and the vibration damping device 40 will move to a position far away from the support platform 30 under the action of this excitation and then fall back onto the support platform 30 in the form of an impact. Although the vibration damping device 40 can still buffer and absorb the vibration caused by the impact to a certain extent during the impact process, optical equipment is a device that is relatively sensitive to vibration. The vibration generated under this condition may still cause damage to the optical equipment. It was precisely because the applicant was aware of the particularity of this excitation method and the sensitivity of optical equipment to vibration that he overcame the technical prejudices of those skilled in the art and creatively proposed the need to A connection structure is provided between the vibration damping device 40 and the support platform 30. When the optical cabin 10 moves away from the support platform 30, the connection structure causes the vibration damping device 40 to undergo tensile deformation. This allows the vibration damping device 40 to reliably absorb vibrations even when the external excitation is in the form of displacement. Furthermore, to ensure the optical cabin 10 retains its lifting function, the applicant further proposes that the connection structure be configured as a first locking structure 41 and a second locking structure 31. By switching between locked and unlocked states, the vibration damping device 40 can absorb vibrations through tensile deformation while the optical cabin 10 retains its lifting function. The specific structure of the first locking structure 41 and the second locking structure 31, and the implementation method of state switching, are exemplarily described in subsequent embodiments and will not be repeated here.

[0053] This invention provides a lifting device with a locking function. The lifting device includes: an optical cabin for accommodating optical equipment; a lifting assembly fixedly connected to the optical cabin to drive its lifting movement; a support platform with a support surface; and a vibration damping device fixedly connected to the optical cabin and located between the optical cabin and the support surface. When the optical equipment is needed, the lifting assembly lifts the optical cabin; when the optical equipment needs to be transported, the lifting assembly lowers the optical cabin and brings the vibration damping device into contact with the support surface, thereby absorbing vibrations acting on the optical cabin. The vibration damping device has a first locking structure, and the support platform has a second locking structure. When the support platform and the vibration damping device are in contact, the first and second locking structures can switch between a locked state and an unlocked state. In the locked state, a locking force is formed between the first and second locking structures. In the unlocked state, the locking force is released. In other words, when the optical cabin needs to be transported, the lifting assembly brings the vibration damping device into contact with the support platform, and the first and second locking structures are locked. In this state, the movement of the optical cabin away from the support platform is transmitted to the vibration damping device by the first and second locking structures, causing the vibration damping device to be stretched and deformed. At the same time, when the optical cabin needs to be used, the first and second locking structures are controlled to switch from the locked state to the unlocked state, so that the locking force is removed, allowing the optical cabin to rise under the drive of the lifting assembly. That is, the vibration damping device can absorb vibration not only when the optical cabin is close to the support platform, but also when the optical cabin is far from the support platform, it can absorb vibration through the deformation caused by compression. This improves the vibration damping capability of the lifting device and reduces the impact of external vibration on the optical equipment. Meanwhile, by keeping the first and second locking structures in the unlocked state, the optical cabin still has the function of lifting.

[0054] In some embodiments, such as Figure 2 As shown, the first locking structure 41 and the second locking structure 31 can be configured in a first direction (the first direction is as shown in the figure). Figure 2The relative movement (indicated by the middle arrow) allows the first locking structure 41 and the second locking structure 31 to switch between locked and unlocked states. This can be understood as follows: when transporting optical equipment, the lifting assembly 20 lowers the optical cabin 10 and brings the first locking structure 41 and the second locking structure 31 closer together. After the optical cabin 10 is in position, relative movement in a first direction is generated between the first locking structure 41 and the second locking structure 31, locking them in a locked state. This allows the vibration damping device 40 to be connected to the support platform 30 via the first and second locking structures 41. Furthermore, when a tendency for the vibration damping device 40 and the support platform 30 to move away from each other arises, this tendency is transmitted to the vibration damping device 40, causing it to undergo tensile deformation. Thus, the vibration damping device 40 can achieve vibration damping through both compressive and tensile deformation, improving... Figure 1 The lifting device 1 in the middle has a vibration reduction capability; when the optical equipment needs to be used, by moving the first locking structure 41 and the second locking structure 31 relative to each other in the first direction, the first locking structure 41 and the second locking structure 31 are switched from the locked state to the unlocked state, the locking force between the first locking structure 41 and the second locking structure 31 is removed, so that the optical cabin 10 can rise under the drive of the lifting assembly 20.

[0055] Wherein, the first direction is not parallel to the vertical direction, which can be understood as the locking state of the first locking structure 41 and the second locking structure 31 will not be switched to the unlocked state under the action of vertical force. When the vibration damping device 40 generates a tendency to move away from the support platform 30, the first locking structure 41 and the second locking structure 31 will not switch from the locked state to the unlocked state under this tendency, thereby reliably transmitting the tendency to the vibration damping device 40 and causing the vibration damping device 40 to undergo tensile deformation. That is, through the reliable connection of the first locking structure 41 and the second locking structure 31, the efficiency is improved. Figure 1 The vibration reduction reliability of the lifting device 1 in the middle. It should be noted that the relative movement of the first locking structure 41 and the second locking structure 31 in the first direction can be achieved by manual operation or by setting an electrically controlled actuator and implementing it through an electronic control system. Moreover, depending on the specific structure of the first locking structure 41 and the second locking structure 31, the relative movement form of the first locking structure 41 and the second locking structure 31 is different. The following is in conjunction with Figure 2 and Figure 3 The structure and relative motion of the first locking structure 41 and the second locking structure 31 are described by way of example. Those skilled in the art should understand that the first locking structure 41 and the second locking structure 31 can also be other than Figure 3 and Figure 4 Other structures shown.

[0056] like Figure 3 As shown, the first locking structure 41A of the first type includes a locking hole 411A, the depth direction of which is perpendicular to a first direction (as shown in the figure). Figure 3 Parallel to the middle arrow, the first type of second locking structure 31A includes a locking pin 311A, which is slidably connected to the support platform 30. The locking pin 311A ​​can slide between a first position and a second position in a first direction. In the first position, the locking pin 311A ​​can extend into the locking hole 411A to form a locked state, that is, sliding the locking pin 311A ​​along the first direction to the first position can lock the first type of first locking structure 41A and the first type of second locking structure 31A. In the second position, the locking pin 311A ​​is located outside the locking hole 411A to form an unlocked state, that is, sliding the locking pin 311A ​​along the first direction to the second position can switch the first type of first locking structure 41A and the first type of second locking structure 31A from the locked state to the unlocked state.

[0057] like Figure 4 As shown, the second type of second locking structure 31B includes a locking opening 311B, which is formed by the support surface 32 being recessed in the vertical direction. The inner wall of the locking opening 311B has an arc groove 312B and a clearance groove 313B. The arc groove 312B is along a first direction (the first direction is as follows). Figure 4 (As shown by the solid arrow in the middle) extends, and the clearance groove 313B extends from the inner wall of the locking hole 311B along the second direction (the second direction is as shown by the arrow in the middle) in the second direction. Figure 4 (As indicated by the dashed arrow) is formed concavely, with the second direction parallel to the radial direction of the arc groove 312B, and the clearance groove 312B extends vertically from the support surface 32 to the arc groove 312B; simultaneously, the second type of first locking structure 41B includes a locking post 411B, which protrudes vertically from the vibration damping device 40, and the outer surface of the locking post 411B has a locking boss 412B, which extends vertically along a third direction (such as...). Figure 4 The locking boss 412B (as indicated by the double-lined arrow) protrudes from the outer surface of the locking post 411B. The locking post 411B is rotatably connected to the vibration damping device 40, and the locking boss 412B can rotate between the third and fourth positions along the first direction.

[0058] During the descent of the optical cabin 10, the locking protrusion 412B can enter the arc groove 312B from the clearance groove 312B. At this time, by rotating the locking pin 411B in the first direction, the locking protrusion 412B is rotated to the third position. The locking protrusion 412B is located in the arc groove 312B and the third direction is not parallel to the second direction, that is, the locking protrusion 412B is not directly below the clearance groove 313B. The locking protrusion 412B abuts against the side wall of the arc groove 312B. This creates a locking force, thereby switching the first locking structure 41B of the second type and the second locking structure 31B of the second type to a locked state; at the fourth position, the third direction is parallel to the second direction, and the locking boss 412B is located directly below the relief groove 313B, so that the locking boss 412B can move upward from the relief groove 312B out of the arc groove 312B, thereby switching the first locking structure 41B of the second type and the second locking structure 31B of the second type from a locked state to an unlocked state.

[0059] In some embodiments, such as Figure 5 As shown, the relative vertical movement of the first locking structure 41 and the second locking structure 31 enables them to switch between a locked state and an unlocked state. Specifically, when the upward vertical force applied by the lifting assembly 20 to the first locking structure 41 exceeds the unlocking threshold, the first locking structure 41 and the second locking structure 31 switch from the locked state to the unlocked state. This can be understood as the vertical force provided by the lifting assembly 20 enabling the first locking structure 41 and the second locking structure 31 to automatically switch between the locked and unlocked states. Furthermore, when the first locking structure 41 and the second locking structure 31 are in the locked state, they can, to a certain extent, transmit the upward vertical force to the vibration damping device 40. To induce tensile deformation in the vibration damping device 40, specifically, when the upward vertical force is less than the unlocking threshold, the first locking structure 41 and the second locking structure 31 remain locked, thereby transmitting the force to the vibration damping device 40 to induce tensile deformation. When the upward vertical force is greater than the unlocking threshold, the first locking structure 41 and the second locking structure 31 switch from the locked state to the unlocked state, allowing them to separate. Furthermore, the vibration damping device 40 and the optical cabin 10 can rise smoothly under the drive of the lifting assembly 20. That is, without requiring additional operation of the first locking structure 41 and the second locking structure 31, the first locking structure 41 and the second locking structure 31 can automatically switch between the locked and unlocked states, thereby... Figure 1The operation of the lifting device 1 is simpler. It should be noted that the first locking structure 41 and the second locking structure 31 can be any structure capable of automatically switching between locked and unlocked states under vertical force, and the switch from locked to unlocked state is not due to structural damage. The following will explain... Figures 6 to 8 The specific structures of the first locking structure and the second locking structure are described by way of example. Those skilled in the art should understand that the first locking structure and the second locking structure can also be other than Figures 6 to 8 Other structures besides those mentioned above.

[0060] like Figure 6 As shown, the third type of first locking structure 41C includes a first latching structure 411C, and the third type of second locking structure 31C includes a second latching structure 311C. In the vertical direction, the first latching structure 411C moves downward, engaging the first latching structure 411C and the second latching structure 311C, thus locking both structures. In the vertical direction, the first latching structure 411C moves upward, separating the first latching structure 411C and the second latching structure 311C, thus switching both structures from locked to unlocked. One of the first latching structure 411C and the second latching structure 311C is an elastic arm with a hook, and the other is a slot that engages with the hook. Both sides of the hook have guide slopes in the vertical direction.

[0061] like Figure 7 As shown, the fourth type of first locking structure 41D includes a friction post 411D, which protrudes vertically from the bottom of the vibration damping device 40. The fourth type of second locking structure 31D includes a friction hole 311D, within which a diaphragm spring 312D is located. Both ends of the diaphragm spring 312D are fixed to the hole wall of the friction hole 311D, and the middle portion of the diaphragm spring 312D protrudes into the friction hole 311D. When the friction post 411D is located within the friction hole 311D, the diaphragm spring 312D can abut against the friction post 411D. The friction between the friction post 411D and the diaphragm spring 312D provides a locking force, thereby locking the fourth type of first locking structure 41D and the fourth type of second locking structure 31D. Figure 5When the vertical upward force provided by the lifting device to the friction column 411D is greater than the maximum static friction between the friction column 411D and the diaphragm spring 312D, the friction column 411D can slide upward relative to the diaphragm spring 312D and move out of the friction hole 311D, thereby switching the fourth type of first locking structure 41D and the fourth type of second locking structure 31D from the locked state to the unlocked state.

[0062] like Figure 8 As shown, the fifth type of first locking structure 41E includes a first magnetic structure 411E, which is fixed to the bottom of the vibration damping device 40. The fifth type of second locking structure 31E includes a second magnetic structure 311E, which is fixed to the support surface 32. The first magnetic structure 411E can attract the second magnetic structure 311E, and the magnetic force between the first magnetic structure 411E and the second magnetic structure 311E can provide a locking force, thereby putting the fifth type of first locking structure 41E and fifth type of second locking structure 31E into a locked state. Figure 5 When the vertical upward force applied by the lifting component 20 to the first magnetic structure 411E is greater than the magnetic force between the first magnetic structure 411E and the second magnetic structure 311E, the first magnetic structure 411E separates from the second magnetic structure 311E, thereby switching the fifth type of first locking structure 41E and the fifth type of second locking structure 31E from the locked state to the unlocked state.

[0063] In some embodiments, such as Figure 1 As shown, there are multiple vibration damping devices 40, which are spaced apart. Each vibration damping device 40 has a first locking structure 41, and the number of second locking structures 31 is the same as the number of vibration damping devices 40. This allows each vibration damping device 40 to achieve vibration damping through both compression and tension deformation, further improving the vibration damping capability of the lifting device 1.

[0064] In some embodiments, such as Figure 9As shown, the bottom of the vibration damping device 40 has a guide post 42, and the support surface 32 has a guide hole 33. In a cross-section perpendicular to the vertical direction, the cross-sectional area of ​​the guide post 42 decreases along the direction in which it extends, thus forming a cone shape that is larger at the top and smaller at the bottom. And / or, in a cross-section perpendicular to the vertical direction, the cross-sectional area of ​​the guide hole 33 decreases along the direction in which it is recessed, thus forming a cone-shaped hole that is larger at the top and smaller at the bottom. During the process of the vibration damping device 40 falling to the support surface 32, the force between the guide post 42 and the guide hole 33 can guide the vibration damping device 40 and the optical cabin 10, allowing the vibration damping device 40 to fall to the predetermined position on the support surface 32. Optionally, the guide post 42 has a first locking structure, and the guide hole 33 has a second locking structure, so that the guide post 42 and the guide hole 33 can achieve locking and unlocking functions while achieving guidance, making the structure of the lifting platform more compact.

[0065] In some embodiments, such as Figure 10 As shown, the lifting device 1 also includes a lifting platform 50, which is housed within the optical cabin 10. The lifting platform 50 is connected to the optical equipment and is used to drive the optical equipment to move up and down relative to the optical cabin. This can be understood as follows: when using the optical equipment, the lifting assembly 20 lifts the optical cabin 10 to the working position, while the lifting platform 50 raises the optical cabin, thus lifting the optical equipment out of the optical cabin 10. When transporting the optical equipment, the lifting assembly 20 lowers the optical cabin 10 to... Figure 1 The support platform 30 is connected to the vibration damping device 40, and the optical equipment is lowered and stored in the optical cabin 10 by the lifting component 20.

[0066] In some embodiments, such as Figure 11 As shown, the lifting assembly 20 includes a ball screw 21, a sleeve 22, and a motor 23. The sleeve 22 is fitted over the ball screw 21 to provide protection and guidance for the ball screw 21. The motor 23 is connected to the ball screw 21 to drive the ball screw 21 to rotate within the sleeve 22. The rotation of the ball screw 21 enables it to move linearly along its extension direction within the sleeve 22. Figure 1The optical cabin 10 is connected to the sleeve 22, enabling it to move up and down. Furthermore, when the ball screw 21 stops rotating, it locks the position of the optical cabin 10 through friction self-locking. The motor 23 is located on one side of the sleeve 22 and is connected to the ball screw 21 via a transmission structure. This reduces the vertical dimensions of the lifting assembly 20 while allowing the motor 23's power to be transmitted to the ball screw 21. Optionally, the lifting assembly 20 also includes a reduction gear 24. The motor 23 is connected to the reduction gear 24, which is connected to the transmission structure. The reduction gear 24 reduces the power output from the motor 23 to torque before transmitting it to the ball screw 21 via the transmission structure, thereby improving the motor 23's driving capability over the optical cabin 10.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
