Technical Field
[0001] This utility model relates to the field of ruggedized laptop technology, and in particular to a ruggedized laptop with a hot-swappable battery. Background Technology
[0002] A laptop computer is a portable personal computer that is small, lightweight, and easy to carry. It is usually equipped with essential devices such as an LCD screen, keyboard, and touchpad, making it suitable for mobile office work and daily use.
[0003] The existing technical solutions have the following shortcomings:
[0004] Currently available rugged laptops present significant safety hazards and operational inconveniences during battery replacement. The process requires users to first power off the laptop and then disassemble it. This disassembly and replacement process carries multiple risks. Firstly, due to the compact internal structure and complex wiring of rugged laptops, improper operation during disassembly could lead to contact issues or component collisions, causing short circuits. Secondly, if short circuits are not controlled promptly, they can escalate, potentially causing battery overheating, swelling, or even explosion – extreme and dangerous situations. These defects not only directly threaten user safety but also risk damage due to unprofessional handling, increasing user costs and maintenance risks.
[0005] Therefore, we need to design a ruggedized laptop based on a hot-swappable battery to solve the problems mentioned above. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the defect that existing laptops require powering off and disassembling to replace the battery. This utility model proposes a rugged laptop with a hot-swappable battery.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a ruggedized laptop with a hot-swappable battery, including a laptop body, the laptop body is covered with a tri-proof shell, and the right side and the rear side of the laptop body are respectively provided with a first wiring area and a second wiring area, the eight corners of the laptop body are respectively fixed with protective corners, the left side of the laptop body is provided with a plug-in area, and a hot-swappable battery compartment is movably connected inside it, the front end of the laptop body is fixed with a portable handle, the inside of the hot-swappable battery compartment is fixed with a connecting block, the laptop body is provided with a self-locking mechanism, and the bottom of the laptop body is provided with two sets of heat dissipation components.
[0008] Preferably, the self-locking mechanism includes a receiving groove, a fixed ring, a movable block, a connecting column, a fixed block, an internal groove, a movable rod, a spring, a pull rod, a limiting groove, and a locking block;
[0009] The receiving slot is located inside the laptop body. A fixing ring is fixed inside the receiving slot, and a connecting post is fixed to one side of the fixing ring. A fixing block is fixed to one side of the connecting post, and a movable block is sleeved on the outside of the connecting post. A limiting groove is opened inside the connecting block, and an internal groove is opened at the upper and lower ends of the limiting groove. A locking block is movably connected inside the internal groove. A movable rod is fixed at one end of the locking block, and a spring is wound around the outside of the movable rod.
[0010] Preferably, the slope of the card block is equal to the slope of the outer slope of the fixing block.
[0011] Preferably, during operation, the locking mechanism allows the locking block to engage with the position below the fixed block, thereby achieving a self-locking effect. Guide grooves are provided inside the laptop body at both ends of the insertion / removal area, and the guide grooves are slidably connected to the guide block.
[0012] Preferably, the hot-swappable battery compartment integrates magnetic electrode contacts, which are made of gold-plated copper alloy with a contact resistance of <0.1Ω.
[0013] Preferably, the tri-proof shell is made of magnesium-aluminum alloy and adopts a fully sealed design. All ports and expansion ports have sealing protection devices, making it dustproof, waterproof, and drop-resistant. It has passed the 1.22M drop test of the laptop body and is IP65 waterproof and dustproof.
[0014] Compared with the prior art, the beneficial effects of this utility model include:
[0015] 1. By incorporating a self-locking mechanism, the hot-swappable battery compartment is secured during installation, maintaining its stability. When inserted into the laptop, the battery compartment moves the connecting block closer to the internal structure of the receiving slot. The sliding connection between the locking block and the fixing block, along with the spring's elasticity, engages the limiting slot at the bottom of the fixing block, achieving a self-locking effect. To remove the battery compartment, simply press it further inwards, moving the connecting block and the inner locking block until they reach the movable block, which then closes to the fixing block. Under the sliding action of the inclined surface on the outer side of the movable block, it can slide out from the outside of the fixed block with the limiting groove, thereby allowing the hot-swappable battery compartment to be removed from the inside of the laptop body. Through this optimized structural design, an innovative magnetic electrode contact module is built in. When replacing components, the magnetic electrode contact can automatically trigger the power-off mechanism through magnetic induction, eliminating the potential safety hazard of electric shock that users may face during the replacement process. In addition, the unique magnetic positioning design, with its strong magnetic guiding effect, can significantly reduce the probability of incorrect component insertion. Actual test data shows that the incorrect insertion rate can be reduced to only 10% (90% lower than the traditional design). This breakthrough design eliminates the need for users to perform a cumbersome shutdown operation when replacing components, completely freeing them from the constraints of traditional disassembly procedures, effectively improving the safety and convenience of operation, and bringing users a more efficient and reassuring user experience.
[0016] 2. The rugged shell is made of magnesium-aluminum alloy and features a fully sealed design. All ports and expansion slots have sealed protection devices, making it dustproof, waterproof, and drop-resistant. It has passed the 1.22M drop test of the laptop body and has an IP65 waterproof and dustproof rating. In conjunction with the above, multiple technologies such as cushioning and shock absorption design and edge reinforcement further enhance the protection of the core components of the laptop body. This effectively reduces the risk of damage to the device from external impacts, dust intrusion, and liquid splashes, significantly extending the product's lifespan and actual use value. At the same time, the portable handle and ergonomically optimized structure make it easy to hold with one hand or carry around, and allow for quick adjustment of the operating angle in various usage scenarios, balancing portability and ease of use to meet the diverse needs of users in mobile office, outdoor work, and other scenarios.

Detailed Implementation
[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0028] To address the technical problem of overcoming the limitation of existing technologies in effectively cleaning slit debris from reverse osmosis membranes, the following solution is disclosed, specifically as follows: Figures 1-8 As shown:
[0029] A ruggedized laptop with a hot-swappable battery includes a laptop body 1, a rugged shell 2 covering the outside of the laptop body 1, a first wiring area 3 and a second wiring area 6 on the right and rear sides of the laptop body 1 respectively, protective corners 7 fixed at the eight corners of the laptop body 1, a plug-in area 4 on the left side of the laptop body 1 with a hot-swappable battery compartment 8 movably connected inside, a portable handle 5 fixed at the front of the laptop body 1, a connecting block 9 fixed inside the hot-swappable battery compartment 8, a self-locking mechanism 10 inside the laptop body 1, and two sets of heat dissipation components 13 at the bottom of the laptop body 1.
[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, by utilizing the tri-proof technology of the tri-proof shell 2 and the protective corner 7 together, the laptop body 1 can be protected, effectively reducing the risk of damage to the device from external impacts, dust intrusion and liquid splashes, and significantly extending the product's service life and actual use value.
[0031] The self-locking mechanism 10 includes a receiving groove 1001, a fixing ring 1002, a movable block 1003, a connecting column 1004, a fixing block 1005, an internal groove 1006, a movable rod 1007, a spring 1008, a pull rod 1009, a limiting groove 1010, and a locking block 1011.
[0032] The receiving slot 1001 is located inside the notebook computer body 1. A fixing ring 1002 is fixed inside the receiving slot 1001. A connecting post 1004 is fixed to one side of the fixing ring 1002. A fixing block 1005 is fixed to one side of the connecting post 1004. A movable block 1003 is sleeved on the outside of the connecting post 1004. A limiting groove 1010 is opened inside the connecting block 9. An internal groove 1006 is opened at the upper and lower ends of the limiting groove 1010. A locking block 1011 is movably connected inside the internal groove 1006. A movable rod 1007 is fixed at one end of the locking block 1011. A spring 1008 is wound around the outside of the movable rod 1007.
[0033] The slope of the inclined surface of the locking block 1011 is equal to the slope of the outer inclined surface of the fixing block 1005;
[0034] During operation, the self-locking mechanism 10 can engage with the position below the fixed block 1005, thereby achieving a self-locking function.
[0035] The hot-swappable battery compartment features eight integrated magnetic electrode contacts made of gold-plated copper alloy with a contact resistance of <0.1Ω.
[0036] Specifically, such as Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, by using 10, the combination installation of 8 can achieve quick disassembly and quick installation with self-locking function, without the user having to turn off the machine and disassemble it to replace the hot-swappable battery compartment 8, which brings convenience to the maintenance work of the staff.
[0037] The rugged shell 2 is made of magnesium-aluminum alloy and features a fully sealed design. All ports and expansion slots have sealing protection devices, making it dustproof, waterproof, and drop-resistant. It has passed the 1.22M drop test of the laptop body and is IP65 waterproof and dustproof.
[0038] In this embodiment, when it is necessary to replace or repair the components of the hot-swappable battery compartment 8 during use, the guiding structure of the guide groove 11 and the guide block 12 will play a key role. Through precise angle and position design, these two guiding components can guide the hot-swappable battery compartment 8 and its matching connecting block 9 to accurately enter the internal space of the laptop body 1. As the hot-swappable battery compartment 8 components are pushed deeper, the connecting block 9 will gradually approach the internal structure of the receiving groove 1001 and form a preliminary docking.
[0039] Secondly, based on the sliding connection between the locking block 1011 and the fixing block 1005, the operator can smoothly push the component. When the operation is in place, the limiting groove 1010 can accurately engage with the bottom of the fixing block 1005. With this ingenious mechanical structure design, a stable limiting and self-locking function is achieved, ensuring that the component remains stable during equipment operation and will not loosen or shift.
[0040] When it is necessary to remove the hot-swappable battery compartment 8 from the device, the operation is equally convenient and efficient. The user only needs to press the hot-swappable battery compartment 8 inwards. This action will cause the connecting block 9 and the inner locking block 1011 to move inwards simultaneously. When it moves to the position of the movable block 1003, it will move the movable block 1003 and bring it close to the fixed block 1005. Utilizing the carefully designed inclined surfaces on the outside of the fixed block 1005 and the movable block 1003, the limiting groove 1010 can slide smoothly out from the outside of the fixed block 1005 through the mechanical principle of inclined sliding, thereby releasing the locking state. Finally, the hot-swappable battery compartment 8 can be completely removed from the inside of the laptop body 1. The whole operation process is both safe and convenient.
[0041] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
