Description

Technical Field

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

[0002] A telescope is an optical instrument that uses lenses, reflectors and other optical devices to observe distant objects. It uses the refraction of light through the lens or the reflection of light by a concave mirror to make it enter a small hole and converge into an image, which is then seen through a magnifying eyepiece.

[0003] At present, most telescopes are protected by outer shells during use. However, when the telescope is accidentally dropped during use, 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 by the impact of the fall, and the precision optical components such as the internal lenses may also be displaced, seriously affecting the normal use and observation accuracy of the telescope, shortening the service life of the telescope. In addition, when using the telescope in some complex terrain environments, if it is accidentally dropped, the telescope is very likely to continue rolling on the slope and collide with surrounding objects, making the telescope frequently damaged by falling, rolling and collision, causing large economic losses and inconvenience to users.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In order to solve the technical problem that the telescope may be seriously damaged when it is accidentally dropped, such as Figure 1-Figure 2 , Figure 4-Figure 7 As shown, the following preferred technical solutions are provided:

[0044] The telescope protection device includes a telescope body 1, an inner shell 2 is installed on the outer sleeve of the telescope body 1, an outer shell 3 is installed on the outer sleeve of the inner shell 2, a deceleration component 4 is installed at the connection between the inner shell 2 and the outer shell 3, and the deceleration component 4 includes an inner cylinder 42 fixed to the outer wall of the inner shell 2, two sliding rods 424 are symmetrically slidably connected in the inner cylinder 42, and anti-slip pads 425 are bonded to the two sliding rods 424. The inner wall of the outer shell 3 is fixed with an outer cylinder 41, and the anti-slip pad 425 is made of a rubber material with high friction, which can be in close contact with the inner wall of the outer cylinder 41 to provide good friction.

[0045] An electric push rod 421 is fixed inside the inner cylinder 42, and a connecting block 422 is fixed to the output end of the electric push rod 421. A connecting rod 423 is hinged on the connecting block 422, and 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 action by controlling the on and off and size of the current, thereby driving the connecting block 422 and the connecting rod 423 to move.

[0046] 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, and the second electromagnet 412 and the third electromagnet 426 are coaxially arranged.

[0047] It should be noted that the sensor 71 is an acceleration sensor 71, and its model is MPU6050. When the telescope falls, it will be in a weightless state. By real-time monitoring and analysis of acceleration data, it can be determined whether the telescope has fallen.

[0048] In the initial state, the electric push rod 421 is in an extended state, and its extended thrust 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 rod 423 will be forced to slide outward under the rotation of the connecting rod 423, so that the two sliding rods 424 will slide out of the inner tube 42 at the same time. As the sliding rods 424 slide out, the anti-slip pads 425 on the top surface of the sliding rods 424 will fit tightly with the inner wall of the outer tube 41, so that the inner tube 42 can be firmly maintained inside the outer tube 41 without sliding. In this way, when the user uses the telescope, the inner shell 2 will not shake inside the outer shell 3, thereby ensuring the stable use of the telescope and improving the user experience.

[0049] When the user accidentally drops the telescope while using it, the telescope will fall rapidly at the moment of falling. 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 recycle. During the recycling process, 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, further reducing the vibration transmission between the inner shell 2 and the outer shell 3, so that when the telescope falls and collides with the ground, it can effectively reduce the damage caused by the collision to it, thereby achieving efficient protection of the telescope, avoiding the occurrence of problems such as damage to the telescope shell 3 and lens displacement caused by falling damage, and improving the protection performance of the telescope during use.

[0050] 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:

[0051] like Figures 6-10 As shown, mounting boxes 5 are fixed on two symmetrical sides of the shell 3, a through hole 51 is opened on the inner wall of the mounting 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 mounting box 5, and the driving assembly 7 includes a motor 73 fixed on the inner top surface of the shell 3, and the output end of the motor 73 is fixedly connected to the transmission shaft 74, and the first annular plate 8 and the second annular plate 9 are rotatably connected to the transmission shaft 74 respectively, a pillar 801 is fixed on the first annular plate 8, a sliding column 804 is slidably connected in the pillar 801, and a pointed cone 809 is fixed on the top surface of the sliding column 804, 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 the other end of the second compression spring 902 is fixedly connected to the anti-sliding block 903.

[0052] The top of the mounting box 5 is transparent, allowing the scanner 72 to scan the floor through it. A cavity 61 is defined within the inner wall of the mounting box 5. A first spring 62 is secured within the cavity 61, the other end of which is fixedly connected to the curved plate 6. Normally, the curved plate 6 acts as a barrier to the first and second annular plates 8 and 9. When the rotational pressure of the annular plates exceeds the pressure of the first spring 62, the curved plate 6 is squeezed into the cavity 61, allowing the first and second annular plates 8 and 9 to slide out.

[0053] A sensor 71 is fixedly connected to the inner wall of the shell 3, a scanner 72 is installed in the installation box 5, and 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.

[0054] like Figure 11-14 As shown, a first groove 81 is defined within the first annular plate 8, a first slot 82 is defined within the transmission shaft 74, a first embedded post 83 is fixedly connected within the first slot 82, a fifth electromagnet 84 is fixedly attached to the first embedded post 83, a second spring 85 is fixedly sleeved on the fifth electromagnet 84, a first abutting post 87 is slidably connected to the first embedded post 83, a first permanent magnet 86 is fixed to the bottom surface of the first abutting post 87, and the other end of the second spring 85 is fixedly connected to the bottom surface of the first abutting post 87. When energized, the fifth electromagnet 84 generates a repulsive force on the first permanent magnet 86, pushing the first abutting post 87 into engagement with the first annular plate 8, thereby locking the first annular plate 88.

[0055] A second groove 91 is defined within the second annular plate 9, and a second slot 92 is defined within the transmission shaft 74. A second embedded post 93 is fixedly connected within the second slot 92. A sixth electromagnet 94 is fixedly secured to the second embedded post 93. A third spring 95 is fixedly sleeved onto the sixth electromagnet 94. A second abutting post 97 is slidably secured to the second embedded post 93. A second permanent magnet 96 is fixed to the top surface of the second abutting post 97, and the other end of the third spring 95 is fixedly secured to the bottom surface of the second abutting post 97. When energized, the sixth electromagnet 94 generates a repulsive force on the second permanent magnet 96, pushing the second abutting post 97 into engagement with the second annular plate 9, thereby locking the second abutting post 97.

[0056] like Figures 16-20 As shown, a notch 802 is provided at the bottom of the pillar 801, a U-shaped rod 803 is rotatably connected inside the pillar 801, the interior of the pillar 801 is hollow, an electromagnetic sheet 805 is fixed to the inner surface of the pillar 801, a first compression spring 806 is fixedly connected to the inner surface of the pillar 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 to the bottom surface of the sliding column 804, a special-shaped groove 808 is provided in the sliding column 804, and the U-shaped rod 803 is slidably connected to the special-shaped groove 808.

[0057] The interior of the mounting block 901 is hollow, and a seventh electromagnet 904 is fixed to the inner surface of the mounting block 901. A third permanent magnet 905 is fixed to the bottom surface of the anti-sliding block 903. When the seventh electromagnet 904 is energized, it generates an attractive force on the third permanent magnet 905, causing the anti-sliding block 903 to slide into the mounting block 901. When the power is off, the anti-sliding block 903 is reset under the action of the second compression spring 902.

[0058] It should be noted that the model of the scanner 72 is YDLIDARX4, which constructs a two-dimensional or three-dimensional image of the ground through scanning, and determines whether the ground is a soil surface or a cement surface based on the ground's flatness, reflectivity and other characteristics.

[0059] In the initial state, if Figure 12-14 As 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.

[0060] 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, the scanner 72 installed in the installation box 5 can perform a comprehensive scan of the ground environment below through the top during the falling process of the telescope. 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 at the same time, 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.

[0061] 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 process, 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.

[0062] 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 causing the first annular plate 8 to slide out.

[0063] As the first annular plate 8 continues to rotate, when it rotates and slides through the through hole 51, the electromagnetic plate 805 is immediately energized. Figure 17 As shown, when the electromagnetic sheet 805 is energized, a magnetic field is generated, which generates an attraction to the first permanent magnet 807. Under the action of this attraction, the slide column 804 slides downward in the support column 801. During the sliding process of the slide 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 slide column 804 slides down, its inclined surface will conflict with the U-shaped rod 803. This conflict will cause the U-shaped rod 803 to slide along the inclined surface to the left vertex position. When the U-shaped rod 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 this movement of the U-shaped rod 803, the sliding column 804 slides upward along the support 801, thereby driving the top cone 809 to slide out and smoothly embed into the soil ground.

[0064] Through the above arrangement, the tip cone 809 can be quickly stuck into the soil at the moment the telescope falls, thereby stopping 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.

[0065] like Figures 18-20As 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 energized again. After the electromagnetic sheet 805 is energized, it generates an attraction to the first permanent magnet 807, causing the slide post 804 to slide down again in the support 801. During the sliding process of the slide post 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 post 804 slides down, its inclined surface will conflict with the U-shaped 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. Since the U-shaped rod 803 is in the V-shaped depression at the bottom, it will limit the sliding column 804, 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 as not to cause damage to it.

[0066] Then start the motor 73 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 slide smoothly into the installation box 5, and then cut off the power to the fifth electromagnet 84. After power is cut 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 reset 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.

[0067] At this point, the telescope can be put into use again. When the telescope falls again, the above series of steps will be repeated to provide reliable protection for the telescope.

[0068] 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 12As shown, the sixth electromagnet 94 is energized. After energization, 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 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 7 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 friction. 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.

[0069] like Figure 9-10 As shown, as the second annular plate 9 continues to rotate, when the second annular plate 9 rotates to contact the arc plate 6, the rotational pressure generated by the friction between the second annular plate 9 and the arc plate 6 is less than the pressure of the first spring 62. After being subjected to the force, the arc plate 6 will squeeze the first spring 62 and embed into the cavity 61, so that the second annular plate 9 can continue to rotate outward, and at the same time as the second annular plate 9 rotates, the seventh electromagnet 904 is turned on. After the seventh electromagnet 904 is energized, it will generate an attraction to the third permanent magnet 905. Under the action of this attraction, the third permanent magnet 905 is forced to drive the anti-sliding block 903 to move downward and squeeze the second compression spring 902, so that the anti-sliding block 903 slides into the mounting block 901. This design ensures that the mounting block 901 will not conflict with the inner surface of the mounting box 5, thereby not affecting the smooth rotation of the second annular plate 9.

[0070] like Figure 9-10 As 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 powered off. After the power is turned off, the third permanent magnet 905 loses its attraction, and the second compression spring 902 uses its own elastic properties to drive the third permanent magnet 905 and the anti-sliding block 903 to reset and slide out, and contact the ground. Through the anti-slip performance of the anti-sliding block 903, it can quickly contact the ground and stop the telescope, effectively avoiding the continuous rolling of the telescope during the falling process, and reducing damage to the telescope.

[0071] like Figure 2As shown, after the telescope is successfully stopped at the dropped position, the user picks it up. During the picking-up process, the seventh electromagnet 904 is energized. After energization, the seventh electromagnet 904 generates an attraction to the third permanent magnet 905. Under the action of the attraction, the third permanent magnet 905 is forced to drive the anti-sliding block 903 to move downward and squeeze the second compression spring 902, so that the anti-sliding block 903 slides into the mounting block 901, and then the motor 73 is started to drive the transmission shaft 74 to drive the second annular plate 9 to rotate in the opposite direction, so that the second annular plate 9 can smoothly slide into the mounting box 5 and wait for the next use. When the telescope falls again, the above steps will be repeated to provide protection for the telescope in a cycle.
