[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An easily maintainable aerospace-grade electronic switch includes a body 1, bolts 2, a panel 3, a connecting mechanism 4, and a guide mechanism 10. The panel 3 is connected to the body 1 via the connecting mechanism 4. The body 1 is provided with bolts 2. The connecting mechanism 4 includes a spring 5, a telescopic rod 13, a connecting block 6, a slide groove 7, a slider 8, and a fixing block 9. One end of the spring 5 is connected to the body 1, and the other end of the spring 5 is connected to the connecting block 6. The telescopic rod 13 is located inside the spring 5, and one end of the telescopic rod 13 is connected to the body 1. 13 The other end is connected to the connecting block 6. The sliding groove 7 is formed on the connecting block 6. One end of the slider 8 is slidably connected to the sliding groove 7. The other end of the slider 8 extends into the fixing block 9. The fixing block 9 is welded to the bottom of the panel 3. The bottom of the fixing block 9 contacts the top of the connecting block 6. The guiding mechanism 10 includes a guide groove 11 and a guide block 12. The guide groove 11 is formed on the body 1. The guide block 12 is set on the panel 3. The guiding mechanism 10 has multiple parts. The front of the panel 3 is provided with a pull rod 14.

[0023] Working principle: During equipment installation, bolts 2 are used to install the main body 1 into the mounting holes at the designated external positions. A fixing block 9 is welded to the bottom of the panel 3. The connection between the panel 3 and the main body 1 is as follows: First, precisely insert the guide block 12 on the panel 3 into the guide groove 11 of the main body 1 to complete the initial positioning and ensure the accuracy and stability of the subsequent connection. Next, manually pull the connecting block 6 to simultaneously extend the built-in spring 5 and the telescopic rod 13. At this time, align the slider 8 with the pre-designed matching groove on the fixing block 9 and push the slider 8 along the slide groove 7 into the groove of the fixing block 9. During this process, to ensure smooth operation, it is recommended that operators check the guide block 12, guide groove 11, slider 8, and the groove of the fixing block 9 before operation. Check the surface for foreign objects; if so, clean it using a dedicated cleaning tool. When pulling the connecting block 6, apply force slowly and evenly, and observe the extension of the spring 5 and the telescopic rod 13 to ensure that the slider 8 is accurately aligned with the groove of the fixing block 9. After positioning the slider 8, release the connecting block 6. The spring 5 and the telescopic rod 13 will rebound due to their own elastic potential energy, causing the panel 3 on the connecting block 6 and the fixing block 9 to move smoothly, achieving precise docking between the panel 3 and the body 1. During the installation of the body 1, the slider 8 hangs naturally under the action of gravity, tightly fitting with the groove of the fixing block 9. This structural design ensures that the slider 8 will not accidentally separate from the groove during normal use, ensuring the overall stability of the equipment. The docking of the body 1 with external equipment... Employing mature, industry-standard technology, the specific operation will not be detailed here. After panel 3 successfully aligns with body 1, the powerful spring 5 and telescopic rod 13 continuously contract until the telescopic rod 13 reaches its maximum contraction position. At this point, under the action of spring 5, panel 3 is firmly pressed onto body 1, preventing further pressing. If internal maintenance of body 1 is required, the operator must grasp the pull rod 14 on the front of panel 3 and pull forcefully to overcome the elasticity of spring 5, separating panel 3 from body 1. During this process, spring 5 and telescopic rod 13 rebound synchronously. After panel 3 separates from body 1, sufficient operating space is created between them. Through precise calculations and simulations, the dimensional requirements for operator hand movements have been comprehensively considered. The space requirement for separating slider 8 from fixed block 9 using small tools is determined. In the complex layout environment inside the spacecraft, even if there are other equipment or cables around, this separation distance can ensure that the staff can operate smoothly and will not affect the maintenance work due to the small space. The staff can use this space to push slider 8 to separate it from the groove of fixed block 9, thereby achieving complete separation of panel 3 from body 1, which facilitates the maintenance work inside body 1. In the microgravity environment of space, when the staff operates slider 8, it may be difficult to apply force due to the loss of gravity assistance. Therefore, the surface of slider 8 is designed with a special texture to increase the friction between it and the staff's gloves, making it easier for the operator to apply force.Meanwhile, the interior of the slide groove 7 is extremely smooth, and the sliding friction of the slider 8 within the slide groove 7 is controlled within a suitable range. Even in a microgravity environment, workers only need to apply a small force to easily push the slider 8. Furthermore, by removing bolt 2, the main body 1 can be separated from the external equipment for comprehensive overall inspection, ensuring the performance and reliability of the equipment.

[0024] In actual operation, if special situations such as slider 8 getting stuck in the groove are encountered, the operator can first use a special micro vibration tool to control its frequency and amplitude within a suitable range to slightly vibrate slider 8 or fixed block 9. This vibration frequency and amplitude have been verified through multiple experiments and can effectively loosen the stuck parts without damaging the equipment. If vibration is ineffective, a small auxiliary tool with magnetism, such as a magnetic probe, can be used to attract slider 8 with magnetic force without direct contact with the equipment, attempting to free it from the stuck state. Throughout the process, the operator must constantly observe the status of slider 8 and fixed block 9 through the visual monitoring window on the equipment or other auxiliary monitoring devices to ensure safe and effective operation and avoid secondary damage to the equipment. When operating, the force of pulling lever 14 should be gradually increased to avoid damage to the equipment due to excessive force. At the same time, the operator can refer to the operation instructions and step descriptions marked on the equipment to ensure the standardization and accuracy of the operation.

[0025] In the microgravity environment of space, the motion characteristics of spring 5 and telescopic rod 13 will change. To ensure their normal operation, a large number of simulated microgravity experiments were conducted during the design phase to optimize and adjust the elastic coefficient of spring 5 and the damping of telescopic rod 13. The experimental results show that in the simulated microgravity environment, spring 5 and telescopic rod 13 can extend and retract normally within the specified stroke range, ensuring reliable connection and separation between panel 3 and body 1. In the high and low temperature alternating environment temperature range of -[low temperature value]℃ to +[high temperature value]℃, the materials used in each component of the electronic switch have good thermal stability. For example, the alloy materials used in connecting block 6, slider 8 and fixing block 9, after multiple high and low temperature alternating cycle tests, ensure the performance stability of the electronic switch in harsh environments.

[0026] If the elasticity of spring 5 weakens, it will cause the panel 3 to be loosely connected to the body 1. This problem should be identified promptly, and spring 5 should be tested with a professional spring force testing instrument during each equipment maintenance. If the spring force of spring 5 decreases significantly, it should be replaced immediately. For the problem of the telescopic rod 13 getting stuck, in addition to trying to resolve it with external vibration, injecting an appropriate amount of special lubricant can reduce the resistance to sticking. If the sticking is caused by damage to internal parts, the telescopic rod 13 must be disassembled according to a strict maintenance procedure, the damaged parts replaced, and a performance test performed after reassembly to ensure that the telescopic rod 13 returns to normal working condition and guarantees the normal use of the electronic switch.

[0027] To improve stability, in this embodiment, multiple guide mechanisms 10 are symmetrically arranged. This layout provides uniform and stable guiding force during the installation and separation of the panel 3 from the body 1. According to mechanical principles, the symmetrically distributed guide blocks 12 and guide grooves 11 can effectively balance the forces acting on the panel 3 during movement, preventing the panel 3 from tilting or shifting. This allows the panel 3 to dock with the body 1 along a precise path, greatly improving the accuracy and stability of the connection.

[0028] To improve the installation effect of the main body 1, in this embodiment, several bolts 2 are provided, and all bolts 2 are made of stainless steel, specifically 316L stainless steel. This is because 316L stainless steel has excellent corrosion resistance and high strength properties. In the harsh environment of space with high radiation and alternating high and low temperatures, its molybdenum-containing component enables it to effectively resist the corrosion of chloride ions.

[0029] The anti-slip effect of the outer wall of the aforementioned pull rod 14 is poor. When the worker's hand comes into contact with the outside of the pull rod 14, it is easy to slip. In order to solve this problem, in this embodiment, the outer wall of the pull rod 14 is provided with anti-slip texture. The anti-slip texture is provided in multiple ways and the multiple anti-slip textures are evenly arranged on the outer wall of the pull rod 14.

[0030] The anti-slip texture can be made of any material. In order to improve the anti-slip effect, in this embodiment, the anti-slip texture is made of rubber.

[0031] To improve the stability of the guide, in this embodiment, the guide block 12 is matched with the guide groove 11.

[0032] In this structure, both the slider 8 and the slide groove 7 adopt a T-shape. The telescopic rod 13 in this structure is a conventional technology on the market, including structures such as telescopic shell, sliding mechanism and limiting mechanism. The dimensions of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
