Description

Technical Field

[0001] The present invention relates to the technical field of telescope protection, and specifically to a telescope protection device. Background Art

[0002] A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. By refracting light through lenses or reflecting light by concave mirrors, the light enters a small hole and converges to form an image, which is then seen through a magnifying eyepiece.

[0003] Currently, most telescopes are protected by setting up an outer shell during use. However, during use, when the telescope accidentally falls, the impact force generated by the collision with the ground will be transmitted to the internal structure through the outer shell, making the outer shell of the telescope easily damaged under the impact of falling, and the internal precision optical components such as lenses may also be displaced, seriously affecting the normal use and observation accuracy of the telescope, shortening the service life of the telescope. Moreover, when using the telescope in some complex terrain environments, if it accidentally falls, the telescope is extremely likely to continuously roll on the slope and collide with surrounding objects, resulting in frequent damage to the telescope caused by falling, rolling, and collision, bringing greater economic losses and inconvenience to users.

[0004] In view of the above problems, a telescope protection device is proposed. Summary of the Invention

Specific implementation mode

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] To solve the technical problem that the telescope will be severely knocked when it accidentally falls, as Figure 1 - Figure 2 , Figure 4 - Figure 7 shown, the following preferred technical solutions are provided: A telescope protection device includes a telescope body 1. An inner shell 2 is sleeved and installed outside the telescope body 1, and an outer shell 3 is sleeved and installed outside the inner shell 2. A shock mitigation component 4 is installed at the connection between the inner shell 2 and the outer shell 3. The shock mitigation component 4 includes an inner cylinder 42 fixed to the outer wall of the inner shell 2. Two sliding rods 424 are symmetrically and slidably connected inside the inner cylinder 42. An anti-slip pad 425 is adhered to the two sliding rods 424. An outer cylinder 41 is fixed to the inner wall of the outer shell 3. The anti-slip pad 425 is made of a rubber material with high friction and can be in close contact with the inner wall of the outer cylinder 41 to provide good friction.

[0021] An electric push rod 421 is fixedly installed inside the inner cylinder 42. A connecting block 422 is fixed to the output end of the electric push rod 421. A connecting rod 423 is hinged to the connecting block 422. The connecting rod 423 is hinged to the sliding rod 424. There are two connecting rods 423 corresponding to the number of sliding rods 424. The electric push rod 421 can realize the telescopic movement by controlling the on / off and magnitude of the current, thereby driving the connecting block 422 and the connecting rod 423 to move.

[0022] A first electromagnet 411 is fixed to the inner wall of the outer cylinder 41. A fourth electromagnet 427 is fixed to the outer wall of the inner cylinder 42. The first electromagnet 411 and the fourth electromagnet 427 are coaxially arranged. A second electromagnet 412 is fixed to the inner wall of the outer cylinder 41. A third electromagnet 426 is installed inside the anti-slip pad 425. The second electromagnet 412 and the third electromagnet 426 are coaxially arranged.

[0023] It should be noted that the sensor 71 is an acceleration sensor 71, and its model is MPU6050. When the telescope drops, it will be in a weightless state. By real-time monitoring and analysis of the acceleration data, it is possible to determine whether the telescope has dropped.

[0024] In the initial state, the electric push rod 421 is in the extended state, and the thrust it exerts can cause the connecting block 422 to slide outward. During this sliding process, the two connecting rods 423 hinged to the connecting block 422 will rotate accordingly, and the two sliding rods 424 hinged to the connecting rods 423 will be forced to slide outward under the rotation of the connecting rods 423, so that the two sliding rods 424 will slide out of the inner cylinder 42 simultaneously. As the sliding rods 424 slide out, the anti-slip pad 425 on the top surface of the sliding rods 424 will closely fit the inner wall of the outer cylinder 41, enabling the inner cylinder 42 to be stably held inside the outer cylinder 41 without sliding. In this way, when the user uses this telescope, the inner shell 2 will not shake inside the outer shell 3, thus ensuring the stable use of the telescope and improving the user experience.

[0025] When the user accidentally drops the telescope during use, the telescope will rapidly fall at the moment of dropping. At this time, the sensor 71 can quickly sense this change and immediately transmit an electrical signal to the electric push rod 421, the first electromagnet 411, the second electromagnet 412, the third electromagnet 426, and the fourth electromagnet 427. After receiving the signal, the electric push rod 421 will drive the connecting block 422 to retract. During the retraction process, as Figure 4 - Figure 5As shown, the two connecting rods 423 rotate, thereby driving the sliding rod 424 to slide into the inner tube 42, so that the sliding rod 424 and the anti-slip pad 425 are separated from the inner wall of the outer tube 41, so that the relative restriction between the inner tube 42 and the outer tube 41 is released. At the same time, in the process of releasing the restriction, the first electromagnet 411, the second electromagnet 412, the third electromagnet 426 and the fourth electromagnet 427 are all energized. Under the action of electromagnetic force, the inner tube 42 can be in a suspended state inside the outer tube 41, so that the inner tube 42 and the outer tube 41 lose the path of vibration transmission during the falling process of the telescope, and further reduce the vibration transmission between the inner shell 2 and the outer shell 3. When the telescope falls and collides with the ground, the damage caused by the collision can be effectively reduced, thereby realizing efficient protection of the telescope, avoiding the occurrence of problems such as damage to the outer shell 3 of the telescope and displacement of the lens due to falling damage, and improving the protection performance of the telescope during use.

[0026] In order to solve the technical problem that the telescope will continue to roll and collide when encountering a slope during the falling process, causing serious damage, such as Figure 1 - Figure 3 , Figure 8 - Figure 22 As shown, the following preferred technical solutions are provided: like Figure 6 - Figure 10 As shown, installation boxes 5 are fixed on two symmetrical sides of the shell 3, and a through hole 51 is opened on the inner wall of the installation box 5. An arc plate 6 is installed on the inner wall of the through hole 51. A driving assembly 7 is installed in the installation box 5, and the driving assembly 7 includes a motor 73 fixed on the inner top surface of the shell 3. The output end of the motor 73 is fixedly connected to a transmission shaft 74, and the transmission shaft 74 is rotatably connected to a first annular plate 8 and a second annular plate 9 respectively. A pillar 801 is fixed on the first annular plate 8, and a sliding column 804 is slidably connected in the pillar 801. A pointed cone 809 is fixed on the top surface of the sliding column 804, and a mounting block 901 is fixed on the second annular plate 9. A second compression spring 902 is fixed in the mounting block 901, and an anti-sliding block 903 is fixedly connected to the other end of the second compression spring 902.

[0027] The top of the installation box 5 is transparent, so that the scanner 72 can scan the ground environment through it. The inner wall of the installation box 5 is provided with a cavity 61, in which a first spring 62 is fixed, and the other end of the first spring 62 is fixedly connected to the arc plate 6. The arc plate 6 can block the first annular plate 8 and the second annular plate 9 in a normal state. When the rotation pressure of the annular plate exceeds the pressure of the first spring 62, the arc plate 6 will be squeezed into the cavity 61, so that the first annular plate 8 and the second annular plate 9 can slide out.

[0028] A sensor 71 is fixedly connected to the inner wall of the shell 3, a scanner 72 is installed in the installation box 5, a first annular groove 75 and a second annular groove 76 are respectively installed on the transmission shaft 74, the first annular plate 8 is slidably sleeved in the first annular groove 75, and the second annular plate 9 is slidably sleeved in the second annular groove 76.

[0029] As Figure 11 - Figure 14 shown, a first groove 81 is formed in the first annular plate 8, a first sliding groove 82 is formed in the transmission shaft 74, a first embedded column 83 is fixedly connected in the first sliding groove 82, a fifth electromagnet 84 is fixed on the first embedded column 83, a second spring 85 is fixedly sleeved on the fifth electromagnet 84, a first abutting column 87 is slidably connected to the first embedded column 83, a first permanent magnet 86 is fixed on the bottom surface of the first abutting column 87, and the other end of the second spring 85 is fixedly connected to the bottom surface of the first abutting column 87. When the fifth electromagnet 84 is energized, a repulsive force is generated on the first permanent magnet 86, and the first abutting column 87 is pushed to fit with the first annular plate 8 to achieve locking.

[0030] A second groove 91 is formed in the second annular plate 9, a second sliding groove 92 is formed in the transmission shaft 74, a second embedded column 93 is fixedly connected in the second sliding groove 92, a sixth electromagnet 94 is fixed on the second embedded column 93, a third spring 95 is fixedly sleeved on the sixth electromagnet 94, a second abutting column 97 is slidably connected to the second embedded column 93, a second permanent magnet 96 is fixed on the top surface of the second abutting column 97, and the other end of the third spring 95 is fixedly connected to the bottom surface of the second abutting column 97. When the sixth electromagnet 94 is energized, a repulsive force is generated on the second permanent magnet 96, and the second abutting column 97 is pushed to fit with the second annular plate 9 to achieve locking.

[0031] As Figure 16 - Figure 20 shown, a notch 802 is formed at the bottom of the support column 801, a U-shaped insertion rod 803 is rotatably connected in the support column 801, the interior of the support column 801 is hollow, an electromagnetic sheet 805 is fixed on the inner surface of the support column 801, a first compression spring 806 is fixedly connected to the inner surface of the support column 801, the first compression spring 806 is fixedly connected to the bottom surface of the sliding column 804, a first permanent magnet 807 is fixed on the bottom surface of the sliding column 804, a special-shaped groove 808 is formed in the sliding column 804, and the U-shaped insertion rod 803 is slidably connected to the special-shaped groove 808.

[0032] The interior of the mounting block 901 is hollow, a seventh electromagnet 904 is fixed on the inner surface of the mounting block 901, a third permanent magnet 905 is fixed on the bottom surface of the anti-sliding block 903, when the seventh electromagnet 904 is energized, an attractive force is generated on the third permanent magnet 905, so that the anti-sliding block 903 slides into the mounting block 901, and when powered off, the anti-sliding block 903 is reset under the action of the second compression spring 902.

[0033] It should be noted that the model of the scanner 72 is YDLIDAR X4, and a two-dimensional or three-dimensional image of the ground is constructed by scanning. According to the characteristics such as the flatness and reflectivity of the ground, it is further judged whether the ground is a soil surface or a cement surface.

[0034] In the initial state, as Figure 12 - Figure 14As shown, the fifth electromagnet 84, the first permanent magnet 86, the sixth electromagnet 94, the second permanent magnet 96, the seventh electromagnet 904 and the third permanent magnet 905 are all in an unpowered state. At this time, the first annular plate 8 and the second annular plate 9 are securely located inside the mounting box 5, and the first annular plate 8, the second annular plate 9 and the transmission shaft 74 remain in a rotatable state.

[0035] During the actual use of the telescope, if it accidentally falls, since the top of the installation box 5 is designed with a transparent material, during the falling process of the telescope, the scanner 72 installed in the installation box 5 can perform a comprehensive scan of the ground environment below through the top. When the scanner 72 recognizes that the ground environment is a soil surface, the fifth electromagnet 84 is immediately energized, and the generated magnetic field forms a repulsive force on the first permanent magnet 86. Under the action of this repulsive force, the first permanent magnet 86 is forced to slide upward, and the second spring 85 connected to its bottom is also synchronously stretched. The first abutment column 87 located above the first permanent magnet 86 slides upward along the first embedded column 83, smoothly enters the first groove 81, and fits tightly with the bottom surface of the first annular plate 8, so that the first abutment column 87 and the first annular plate 8 are firmly fitted, thereby locking and fixing the first annular plate 8 and the transmission shaft 74 to form a whole.

[0036] Then the first annular plate 8 can rotate synchronously with the rotation of the transmission shaft 74. Figure 11 and Figure 15 As shown, the motor 73 is then started to drive the transmission shaft 74 to rotate. Due to the stopping effect between the first abutment column 87 and the first annular plate 8, the first annular plate 8 will rotate with the transmission shaft 74. During the rotation, although there is no stopping connection between the second annular plate 9 and the transmission shaft 74, due to the existence of friction, the second annular plate 9 will also be driven to rotate. When the second annular plate 9 rotates to contact the arc plate 6, the rotational pressure generated by the friction between the two is less than the pressure that the first spring 62 can withstand. Therefore, under the obstruction of the arc plate 6, the second annular plate 9 will always remain in the installation box 5 and will not slide out, and will not cause any impact on the subsequent possible sliding out action of the second annular plate 9.

[0037] When the first annular plate 8 continues to rotate under the drive of the motor 73, the pressure generated by the rotation of the first annular plate 8 is significantly greater than the pressure that the first spring 62 itself can withstand due to the power provided by the motor 73. Therefore, when the first annular plate 8 rotates to a position opposite to the through hole 51, it will conflict with the arc plate 6. After being subjected to this pressure, the arc plate 6 will squeeze the first spring 62 connected to it, causing the first spring 62 to shrink and slide into the cavity 61, thereby allowing the first annular plate 8 to slide out.

[0038] As the first annular plate 8 continues to rotate, when it rotates and slides through the through hole 51, the electromagnetic sheet 805 is immediately energized. Figure 17 As shown, when the electromagnetic sheet 805 is energized, a magnetic field is generated, which generates an attraction force on the first permanent magnet 807. Under the action of this attraction force, the sliding column 804 slides downward in the pillar 801. During the sliding process of the sliding column 804, the first compression spring 806 is squeezed. At the same time, due to the special inclined surface structure design at the top of the special-shaped groove 808, when the sliding column 804 slides down, its inclined surface will conflict with the U-shaped plug 803. This conflict will cause the U-shaped plug 803 to slide along the inclined surface to the left vertex position. When the U-shaped plug 803 reaches the left vertex, the electric The magnetic sheet 805 is powered off. After the power is off, the first permanent magnet 807 loses the attraction of the electromagnetic sheet 805. At this time, the first compression spring 806 drives the first permanent magnet 807 to reset by virtue of its own elastic performance. At the same time, the U-shaped rod 803 releases the relative limit state, and then slides down along the left inclined surface of the special-shaped groove 808, and finally enters the V-shaped depression at the bottom of the special-shaped groove 808. With the movement of the U-shaped rod 803, the sliding column 804 slides upward along the support column 801, thereby driving the top cone 809 to slide out and smoothly embed into the soil ground.

[0039] Through the above arrangement, the tip cone 809 can be quickly stuck into the soil at the moment the telescope falls, so as to stop the telescope in time, effectively avoiding the continuous rolling of the telescope when it falls on the slope, greatly reducing the risk of damage to the telescope caused by continuous rolling, and providing further effective protection for the telescope.

[0040] like Figure 18 - Figure 20 As shown, after the telescope is successfully stopped at the dropped position, the user picks it up. During the picking process, the electromagnetic sheet 805 is powered on again. After the electromagnetic sheet 805 is powered on, an attraction is generated on the first permanent magnet 807, so that the slide column 804 slides down again in the support column 801. During the sliding process of the slide column 804, the first compression spring 806 will continue to be squeezed. At the same time, since the right part of the special-shaped groove 808 is also provided with an inclined surface, when the slide column 804 slides down, its inclined surface will conflict with the U-shaped plug rod 803. This friction The U-shaped rod 803 is forced to rotate to the right and slide upward along the inclined surface on the right. When the U-shaped rod 803 slides to the right apex, it will be squeezed into the V-shaped depression at the top. When the U-shaped rod 803 returns to its initial state, the electromagnetic sheet 805 is powered off. When the U-shaped rod 803 is in the V-shaped depression at the bottom, the sliding column 804 is limited, so that the pointed cone 809 will not pop out and contact the inner wall of the installation box 5 when it is recovered into the installation box 5, so that it will not be damaged.

[0041] Next, the motor 73 is started to drive the transmission shaft 74, driving the first annular plate 8 to rotate in the opposite direction, so that the first annular plate 8 can smoothly slide into the installation box 5, and then the fifth electromagnet 84 is powered off. After power is off, the first permanent magnet 807 loses its attraction, and the second spring 85 uses its own elastic properties to drive the first permanent magnet 86 and the first abutment column 87 to return to their original position and slide down, so that the first abutment column 87 is separated from the first annular plate 8, thereby releasing the limit restriction between the first abutment column 87 and the first annular plate 8.

[0042] At this point, the telescope can be put into use again. When the telescope falls again, the above series of steps will be repeated, providing reliable protection for the telescope over and over again.

[0043] When the telescope accidentally falls, due to the transparent property of the top of the installation box 5, the scanner 72 can scan the ground environment through the top. If the scanning result shows that the ground environment is a cement floor, Figure 12 As shown, the sixth electromagnet 94 is powered on. After power is turned on, the sixth electromagnet 94 generates a repulsive force on the second permanent magnet, causing the second permanent magnet to slide downward and drive the third spring 95 to stretch. The second abutment column 97 located at the bottom of the second permanent magnet 96 will slide downward accordingly and enter the second groove 91, and tightly contact the top surface of the second annular plate 9, so that the transmission shaft 74 and the second annular plate 9 form a whole. The second annular plate 9 can rotate with the rotation of the transmission shaft 74, and then the motor 73 is started to drive the transmission shaft 74 to rotate. Due to the second abutment column 9 There is a stopping effect between the first annular plate 8 and the second annular plate 9, and the second annular plate 9 will rotate with the transmission shaft 74. During the rotation process, although there is no stopping connection between the first annular plate 8 and the transmission shaft 74, the first annular plate 8 will also rotate under the drive of the friction force. When the first annular plate 8 rotates to contact with the arc plate 6, the rotation pressure generated by the friction between the two is less than the pressure of the first spring 62. Therefore, under the obstruction of the arc plate 6, the first annular plate 8 will always be in the installation box 5 and will not slide out, and will not affect the subsequent rotation and sliding out of the second annular plate 9.

[0044] like Figure 9 - Figure 10As shown, as the second annular plate 9 continues to rotate, when the second annular plate 9 rotates to contact the arc plate 6, since the rotational pressure generated by the frictional force between the second annular plate 9 and the arc plate 6 is less than the pressure of the first spring 62, the arc plate 6 will squeeze the first spring 62 and embed into the cavity 61 after being stressed, enabling the second annular plate 9 to continue to rotate outward. Meanwhile, when the second annular plate 9 rotates, the seventh electromagnet 904 is turned on. After the seventh electromagnet 904 is energized, it will generate an attractive force on the third permanent magnet 905. Under the action of this attractive force, the third permanent magnet 905 drives the anti-slip block 903 to move downward and squeezes the second compression spring 902, causing the anti-slip block 903 to slide into the mounting block 901. This design ensures that the mounting block 901 does not contact the inner surface of the mounting box 5, thus not affecting the smooth rotation out of the second annular plate 9.

[0045] As Figure 9 - Figure 10 shown, as the second annular plate 9 continues to rotate, when it rotates and slides out of the through hole 51, the seventh electromagnet 904 is de-energized. After being de-energized, the third permanent magnet 905 loses the attractive force. The second compression spring 902 uses its elastic property to drive the third permanent magnet 905 and the anti-slip block 903 to reset and slide out, and make contact with the ground. Through the anti-slip performance of the anti-slip block 903, it can quickly contact the ground and then stop the telescope, effectively avoiding the continuous rolling of the telescope during the falling process and reducing the damage to the telescope.

[0046] As Figure 2 shown, when the telescope is successfully stopped at the falling position, the user picks it up. During the picking-up process, the seventh electromagnet 904 is energized. After being energized, the seventh electromagnet 904 will generate an attractive force on the third permanent magnet 905. Under the action of the attractive force, the third permanent magnet 905 drives the anti-slip block 903 to move downward and squeezes the second compression spring 902, causing the anti-slip block 903 to slide into the mounting block 901. Then, the motor 73 is started to drive the transmission shaft 74 to drive the second annular plate 9 to rotate in the reverse direction, enabling the second annular plate 9 to smoothly slide into the mounting box 5 and wait for the next use. When the telescope falls again subsequently, the above steps will be repeated to provide protection for the telescope in a cyclic manner.
