Description

Technical Field

[0001] This invention relates to the field of chassis technology, and in particular to a chassis and electronic equipment. Background Technology

[0002] Server chassis typically feature a cover lock and an intrusion switch on the top cover. The cover lock requires tools to open, and once the cover is open, the intrusion switch pops up, triggering the system and recording the opening information for software security. However, issues such as chassis cover deformation, arching, or high wind pressure can cause the cover to fail to accurately press the intrusion switch, leading to false alarms, or the cover lock may malfunction. Related technologies often place the cover lock and intrusion switch on the side wall of the chassis base. While this reduces the impact of cover deformation, it can result in uneven force distribution on the cover when it is in position, leading to uneven gaps between the left and right sides of the cover when the chassis is moved.

[0003] Therefore, improving the reliability of the chassis is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a chassis and electronic equipment that can effectively prevent deformation of the chassis cover, improve the reliability of the cover lock, and reduce the probability of false alarms from the intrusion switch.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A chassis includes: a chassis base; a chassis top cover, detachably mounted on the chassis base, with a top cover lock and a top cover limiting member on the side of the chassis top cover near the chassis base; a crossbeam support frame spanning the middle of the chassis base, with a top cover limiting part on the crossbeam support frame, the top cover limiting member engaging with the limiting part along the height direction of the chassis base when the chassis top cover is installed in place; a locking pin and an intrusion switch located in the middle of the crossbeam support frame, the positions of the locking pin and the intrusion switch corresponding to the position of the top cover lock, the top cover lock being used to lock the locking pin, and the intrusion switch being used to pop open and conduct when the chassis top cover is separated from the chassis base.

[0007] The present invention also provides an electronic device comprising a chassis according to any one of the above.

[0008] The chassis provided by this invention has the following advantages: By adding a crossbeam support frame, which spans the middle of the chassis base, and placing the locking pin and intrusion switch in the middle of the crossbeam support frame, the locking pin and intrusion switch are located in the middle of the chassis base under the support of the crossbeam support frame. When locking the chassis cover, it avoids locking only the edge of the chassis cover, effectively reducing the problem of uneven gaps between the left and right sides of the chassis cover when the chassis is moved. At the same time, a cover limiting component is provided on the side of the chassis cover near the chassis base, and a cover limiting part is provided on the crossbeam support frame. When the chassis cover is installed in place, the cover limiting component engages with the limiting part along the height direction of the chassis base. Through the cooperation of the cover limiting component and the cover limiting part, the chassis cover can be locked and limited in the height direction, effectively avoiding the adverse effects of insufficient strength in the middle area of ​​the chassis cover on the intrusion switch, thereby jointly improving the reliability of the cover lock and the intrusion switch.

[0009] Furthermore, during the sliding installation of the chassis cover, the cover lock can smoothly cooperate with the locking pin and the intrusion switch. The intrusion switch has a push-button structure. When the chassis cover is placed on the chassis base, the cover lock can press the intrusion switch. When the chassis cover is separated from the chassis base, the cover lock separates from the intrusion switch, so that the intrusion switch pops open and conducts. The intrusion switch is electrically connected to the system inside the chassis. When the chassis cover is opened, the intrusion switch pops open and conducts. At this time, the intrusion switch is triggered and the information that the chassis has been opened is uploaded and recorded, which plays a role in software security protection.

[0010] The chassis provided by this invention, by adding a crossbeam support frame spanning the middle of the chassis base, and placing the locking pin and intrusion switch on the crossbeam support frame, can fully utilize the crossbeam support frame located in the middle of the chassis base, thereby locking the middle of the chassis cover. This allows the cover lock to be positioned in a more advantageous position within the chassis cover, reducing uneven stress on the cover during handling and effectively improving the reliability of the cover lock. Simultaneously, through the cooperation of the cover limiting component and the cover limiting part, the chassis cover can be locked and limited in the height direction, effectively reducing the risk of chassis cover deformation and the probability of false alarms from the intrusion switch, thus meeting the chassis's safety protection requirements.

[0011] In one embodiment, the two ends of the crossbeam support frame are further provided with elastic buckle components, which can extend or retract from the ends of the crossbeam support frame; the side plate of the chassis base is also provided with a crossbeam fixing part, which has a buckle limiting groove for the elastic buckle components to be inserted. With the above configuration, the elastic buckle components extend and retract at the ends of the crossbeam support frame to achieve locking and unlocking between the elastic buckle components and the chassis base; the crossbeam support frame is installed from top to bottom along the height direction of the chassis base. When the elastic buckle components engage with the buckle limiting grooves, the elastic buckle components and the chassis base are locked, and the crossbeam support frame is fixed to the chassis base. When the elastic buckle components unlock from the buckle limiting grooves, the crossbeam support frame can be disassembled from the chassis base, facilitating the assembly and disassembly of the crossbeam support frame on the chassis base, making operation convenient.

[0012] In one embodiment, the upper cover limiting component is a limiting pin, and the upper cover limiting part is a limiting hole. The opening direction of the limiting hole is opposite to the second direction. During the installation of the chassis upper cover, the limiting pin can be pushed into the limiting hole and engage with the limiting hole along the height direction of the chassis base. This configuration, through the cooperation of the limiting pin and the limiting hole, and with the opening direction of the limiting hole opposite to the second direction, means that during the installation of the chassis upper cover along the second direction, the limiting pin can be simultaneously driven into the limiting hole. This achieves engagement of the limiting pin and the limiting hole along the height direction while completing the installation of the chassis upper cover. This not only does not affect the installation efficiency of the chassis upper cover but also increases the reliability of the chassis upper cover in the height direction, reduces the risk of separation between the chassis upper cover and the intrusion switch when the cover is not open, and ensures the reliability of the intrusion switch.

[0013] In one embodiment, the crossbeam support frame is further provided with crossbeam mounting nails at both ends, and the side plate of the chassis base is further provided with a crossbeam mounting groove. The crossbeam mounting nails can be inserted into the crossbeam mounting grooves and engaged with the crossbeam mounting grooves in a second direction. Specifically, the crossbeam support frame and the chassis base can be fixed together by means of an elastic snap-fit ​​assembly, and the crossbeam mounting nails on the crossbeam support frame can cooperate with the crossbeam mounting grooves on the chassis base to achieve accurate positioning of the crossbeam support frame and the chassis base. This improves the positional accuracy and installation efficiency of the crossbeam support frame and ensures that the elastic snap-fit ​​assembly can be smoothly engaged and fixed with the chassis base.

[0014] In one embodiment, the system further includes electrical components mounted within the chassis base, with limiting pins at both ends of the electrical components. At least one side of the crossbeam support frame along the second direction is also provided with an electrical component limiting groove, into which the limiting pins can be inserted and engaged with the groove along the first direction. With this configuration, the crossbeam support frame not only limits and locks the chassis cover but also effectively supports the electrical components. The opening of the limiting groove faces the chassis cover, and the electrical components are installed from top to bottom. The limiting groove allows for quick positioning of the limiting pins and fixation in both the first and second directions, ensuring the reliability of the electrical components. Simultaneously, it reduces the need for support structures for electrical components in related technologies, saving space and lowering manufacturing costs.

[0015] In one embodiment, the crossbeam support frame includes a main crossbeam support and a platform support. The main crossbeam support spans across the chassis base, and the platform support is detachably mounted on the side of the middle portion of the main crossbeam support. The locking pin and intrusion switch are both located on the platform support; furthermore, the extension direction of the platform support is perpendicular to the extension direction of the main crossbeam support. This configuration, by separating the main crossbeam support and the platform support, improves the positional flexibility of the platform support, accommodating different types of chassis covers. Furthermore, the platform support is installed on the side of the main crossbeam support opposite to the second direction so that during chassis cover installation, the cover lock can first move to the position of the platform support, facilitating its engagement with the locking pin and intrusion switch, and preventing the main crossbeam support from interfering with the translation of the cover lock.

[0016] The electronic device provided by the present invention is equipped with the aforementioned chassis. Since the chassis has the aforementioned technical effects, the electronic device equipped with the chassis should also have the corresponding technical effects. Attached Figure Description

Detailed Implementation

[0033] The core of this invention is to provide a chassis and electronic equipment that can significantly improve the reliability of physical and software security protection of the chassis and reduce maintenance costs.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] This invention primarily addresses the problem that when the locking pin and intrusion switch are placed in the middle, the chassis cover is prone to deformation due to its thinness in the middle, leading to the locking pin slipping and failing, as well as false alarms from the intrusion switch.

[0038] In this implementation, please refer to Figure 1 , Figure 4 , Figure 5As shown in Figure 9(c), the chassis includes: a chassis base 1; a chassis top cover 4, detachably mounted on the chassis base 1, with a top cover lock 42 and a top cover limiting member 43 on the side of the chassis top cover 4 near the chassis base 1; a crossbeam support frame 2, spanning the middle of the chassis base 1, with a top cover limiting part 219 on the crossbeam support frame 2, and the top cover limiting member 43 engaging with the limiting part along the height direction of the chassis base 1 when the chassis top cover 4 is installed in place; a locking pin 222 and an intrusion switch 23, disposed on the crossbeam support frame 2. In the middle, the positions of the locking pin 222 and the intrusion switch 23 correspond to the positions of the top cover lock 42. The top cover lock 42 is used to lock the locking pin 222, and the intrusion switch 23 is used to pop open and conduct when the chassis top cover 4 is separated from the chassis base 1. The intrusion switch 23 and the top cover limiting part 219 should be set adjacent to each other on the crossbeam support frame 2. It is precisely because the top cover limiting part 219 limits the chassis top cover 4 that the pressure contact reliability of the chassis top cover 4 to the intrusion switch 23 is improved and the risk of false alarm of the intrusion switch 23 is reduced.

[0039] Specifically, the chassis base 1 includes a front window, a rear window, a base, and a side panel. The front window, rear window, base, and side panel surround to form a cavity with an opening at the top. Electrical components 3 and other parts are placed inside the chassis base 1. The chassis can be a chassis for electronic devices such as servers. The chassis top cover 4 is detachably installed at the opening of the chassis base 1, so that the chassis forms a complete enclosure.

[0040] The chassis provided by the present invention, by adding a crossbeam support frame 2, spans the middle of the chassis base 1, and the locking pin 222 and the intrusion switch 23 are set in the middle of the crossbeam support frame 2; under the support of the crossbeam support frame 2, the locking pin 222 and the intrusion switch 23 are located in the middle position of the chassis base 1. When locking the chassis cover 4, it can avoid locking only the edge of the chassis cover 4, and can effectively reduce the problem of uneven gap between the left and right sides of the chassis cover 4 when the chassis is moved.

[0041] Meanwhile, the top cover 4 of the chassis is also provided with a top cover limiting member 43 on the side near the chassis base 1, and the crossbeam support frame 2 is provided with a top cover limiting part 219. When the top cover 4 of the chassis is installed in place, the top cover limiting member 43 engages with the limiting part along the height direction of the chassis base 1. Through the cooperation of the top cover limiting member 43 and the top cover limiting part 219, the top cover 4 of the chassis can be engaged and limited in the height direction, effectively avoiding the adverse effects of insufficient strength in the middle area of ​​the top cover 4 on the intrusion switch 23, thereby jointly improving the reliability of the top cover lock 42 and the intrusion switch 23.

[0042] Furthermore, during the sliding installation of the chassis cover 4, the cover lock 42 can smoothly cooperate with the locking pin 222 and the intrusion switch 23. The intrusion switch 23 is a push-button type structure. When the chassis cover 4 is placed on the chassis base 1, the cover lock 42 can press the intrusion switch 23. When the chassis cover 4 is separated from the chassis base 1, the cover lock 42 separates from the intrusion switch 23, so that the intrusion switch 23 pops open and conducts. The intrusion switch 23 is electrically connected to the system inside the chassis. When the chassis cover 4 is opened, the intrusion switch 23 pops open and conducts. At this time, the intrusion switch 23 is triggered and the information that the chassis has been opened is uploaded and recorded, which plays a role in software security protection.

[0043] The chassis provided by this invention, by adding a crossbeam support frame 2, spans the middle of the chassis base 1, and the locking pin 222 and intrusion switch 23 are set on the crossbeam support frame 2, can make full use of the crossbeam support frame 2 located in the middle of the chassis base 1, thereby locking the middle of the chassis cover 4, so that the cover lock 42 is located in a more advantageous position in the chassis cover 4, reducing the problem of uneven force on the chassis cover 4 during transportation, effectively improving the reliability of the cover lock 42. At the same time, through the cooperation of the cover limiting member 43 and the cover limiting part 219, the chassis cover 4 can be locked and limited in the height direction, effectively reducing the risk of deformation of the chassis cover 4, reducing the probability of false alarm of the intrusion switch 23 by the chassis cover 4, and meeting the safety protection requirements of the chassis.

[0044] In some embodiments, the crossbeam support 2 extends along a first direction, the chassis cover 4 is installed along a second direction, and the cover lock 42 is used to lock the locking pin 222 along the second direction; and the first direction, the second direction, and the height direction are perpendicular to each other. Specifically, the crossbeam support 2 extends along the first direction, and the chassis cover 4 is installed along the second direction. The first direction is perpendicular to the second direction. Specifically, the first direction can be along the left-right direction of the chassis base 1, and the second direction can be along the front-back direction of the chassis base 1. That is, the crossbeam support 2 spans across the left-right direction of the chassis base 1, and the chassis cover 4 is installed along the front-back direction of the chassis base 1. With this configuration, when the chassis cover 4 needs to be installed, the chassis cover 4 is first placed on the chassis base 1, and then the chassis cover 4 is pushed along the second direction until the chassis cover 4 is installed in place, and the locking pin 222 is locked in the second direction by the cover lock 42.

[0045] In some embodiments, the crossbeam support frame 2 is further provided with elastic buckle components at both ends along the first direction. The elastic buckle components can extend or retract from the ends of the crossbeam support frame 2. The side plate of the chassis base 1 is also provided with a crossbeam fixing part, and the crossbeam fixing part is provided with a buckle limiting groove 12 for the elastic buckle components to be inserted. With the above configuration, the elastic buckle components extend and retract at the ends of the crossbeam support frame 2 to achieve locking and unlocking between the elastic buckle components and the chassis base 1. The crossbeam support frame 2 is installed from top to bottom along the height direction of the chassis base 1. When the elastic buckle components are engaged with the buckle limiting groove 12, the elastic buckle components and the chassis base 1 are locked, and the crossbeam support frame 2 is fixed on the chassis base 1. When the elastic buckle components are unlocked from the buckle limiting groove 12, the crossbeam support frame 2 can be disassembled from the chassis base 1, which facilitates the assembly and disassembly of the crossbeam support frame 2 on the chassis base 1 and is easy to operate.

[0046] In some embodiments, the elastic latch assembly includes a movable latch 24, a movable latch cover 26, and a reset elastic component 25. The movable latch cover 26 is fixed on the crossbeam support frame 2, and the movable latch 24 is located between the movable latch cover 26 and the crossbeam support frame 2. The movable latch 24 is slidable relative to the crossbeam support frame 2, and the sliding direction of the movable latch 24 is parallel to a first direction. The movable latch 24 can extend or retract from the end of the crossbeam support frame 2 through its own sliding. The reset elastic component 25 abuts against the movable latch 24 to drive the movable latch 24 to reset when there is no external force acting on it. When there is no external force acting on the movable latch 24, that is, when the movable latch 24 is in its initial state, the movable latch 24 can extend from the end of the crossbeam support frame 2 for easy engagement and fixation with the crossbeam fixing part of the chassis base 1.

[0047] In some embodiments, the crossbeam support frame 2 is also provided with a plurality of limiting studs 212, the movable buckle cover plate 26 is connected to the limiting studs 212, and the movable buckle 24 is provided with a plurality of waist-shaped limiting stud holes 242, the limiting studs 212 penetrate through the limiting stud holes 242, and the limiting stud holes 242 can slide relative to the limiting studs 212 to limit the movement stroke of the movable buckle 24; specifically, when the movable buckle 24 slides along the first direction, the limiting stud holes 242 reciprocate, and the limiting studs 212 limit the movement limit position of the movable buckle 24 by blocking the limiting stud holes 242, thereby limiting the movement stroke of the movable buckle 24. Furthermore, to facilitate the installation and positioning of the movable snap-on cover plate 26, a limiting boss is provided on the movable snap-on cover plate 26, and a positioning hole 215 for the movable snap-on cover plate is provided on the crossbeam support frame 2. Before the movable snap-on cover plate 26 is installed and fixed, the limiting boss and the positioning hole 215 of the movable snap-on cover plate are first matched and positioned to facilitate the fastening connection between the movable snap-on cover plate 26 and the limiting stud 212, thereby improving the installation accuracy and efficiency.

[0048] In some embodiments, the movable buckle 24 is provided with a buckle hole 241, and the crossbeam support frame 2 is provided with a movable buckle operation hole 214. The movable buckle operation hole 214 is an oblong hole, and at least part of the structure of the buckle hole 241 coincides with the movable buckle operation hole 214. When the buckle hole 241 moves to the inside of the oblong hole along the first direction under the action of external force, the reset elastic member 25 is compressed, and the movable buckle 24 retracts from the end of the crossbeam support frame 2. When there is no external force acting on the buckle hole 241, the reset elastic member 25 drives the movable buckle 24 to reset, and the movable buckle 24 extends from the end of the crossbeam support frame 2. Specifically, by using the limiting stud hole 242 and the limiting stud 212 to limit the locking hole 241 of the movable buckle 24, the locking hole 241 can be limited at the same time, ensuring that the locking hole 241 always coincides with the movable buckle operating hole 214. This is to make it convenient for the operator to access the locking hole 241 through the movable buckle operating hole 214, thereby facilitating the pressing of the movable buckle 24 and allowing it to retract smoothly from the end of the crossbeam support frame 2, which is convenient for assembly.

[0049] In some embodiments, the crossbeam support frame 2 is also provided with a gripping hole 2111. The gripping hole 2111 is spaced apart from the movable buckle operation hole 214, and the gripping hole 2111 is located inside the movable buckle operation hole 214 along the first direction. The gripping hole 2111 is provided to facilitate the operator to press with two fingers for easy operation.

[0050] In some embodiments, the movable buckle 24 is provided with a buckle protrusion. When the movable buckle 24 is in the initial state, the buckle protrusion can extend from the end of the crossbeam support frame 2 and engage with the buckle limiting groove 12. The number of buckle protrusions can be multiple to improve reliability.

[0051] In some embodiments, please refer to Figures 2(c), 3(a) and 3(b), the side plate of the chassis base 1 is also provided with a top cover fixing groove 13. The top cover fixing groove 13 includes an inlet section and a limiting section. The inlet section extends along the height direction of the chassis base 1, and the limiting section extends along the second direction. The chassis top cover 4 is provided with top cover mounting posts 44 at both ends along the first direction. The top cover mounting posts 44 can enter the limiting section from the inlet section. When the chassis top cover 4 is installed in place, the top cover mounting posts 44 abut against the side of the limiting section away from the inlet section. Specifically, the chassis cover 4 includes a chassis cover body 41, a cover lock 42, a cover limiting member 43, and a cover mounting post 44. The cover lock 42, cover limiting member 43, and cover mounting post 44 are all mounted on the chassis cover body 41. The cover lock 42 can lock the locking pin 222 using a locking tongue; that is, when the chassis cover 4 needs to be removed, the locking tongue is rotated to avoid the locking pin 222. As shown in Figures 9(a) to 9(c), the chassis cover 4 is plate-shaped and can be translated relative to the chassis base 1 until the cover mounting post 44 moves to the inlet section. Position the chassis cover 4 and then remove it along the height direction. When the chassis cover 4 is installed on the chassis base 1, first align the top cover mounting post 44 of the chassis cover 4 with the guide section of the top cover fixing groove 13, then place the chassis cover 4 downwards until the top cover mounting post 44 is completely inserted into the bottom of the guide section. At this time, push the chassis cover 4 to move horizontally, and the top cover mounting post 44 abuts against the limiting section of the top cover fixing groove 13. At this time, rotate the locking tongue in the opposite direction, and the locking tongue engages with the locking pin 222. The chassis cover 4 cannot be retracted, and the installation of the chassis cover 4 is completed, which is convenient for operation.

[0052] In some embodiments, the upper cover limiting member 43 is a limiting pin, and the upper cover limiting part 219 is a limiting hole. The opening direction of the limiting hole is opposite to the second direction. During the installation of the chassis upper cover 4, the limiting pin can be pushed into the limiting hole and engaged with the limiting hole along the height direction of the chassis base 1. With the above arrangement, through the cooperation of the limiting pin and the limiting hole, and the opening direction of the limiting hole being opposite to the second direction, that is, during the installation of the chassis upper cover 4 along the second direction, the limiting pin can be driven into the limiting hole simultaneously. While completing the installation of the chassis upper cover 4, the limiting pin and the limiting hole can be engaged along the height direction. This will not affect the installation efficiency of the chassis upper cover 4, but will also increase the reliability of the chassis upper cover 4 in the height direction, reduce the risk of separation of the chassis upper cover 4 from the intrusion switch 23 in the non-open state, and ensure the reliability of the intrusion switch 23.

[0053] In some embodiments, the limiting hole is located on the first side of the crossbeam support frame 2 along the second direction, and the limiting pin slides and moves from the first side to the second side of the crossbeam support frame 2 along the second direction to enter the limiting hole; this arrangement is to facilitate the installation of the chassis cover 4 onto the chassis base 1 while the limiting pin enters the limiting hole, making operation convenient.

[0054] In some embodiments, the limiting pin is an I-shaped pin. The head of the I-shaped pin engages with the limiting hole to prevent the I-shaped pin from moving away from the limiting hole, thereby locking the position of the chassis cover 4 and preventing the chassis cover 4 from bulging. The limiting hole gradually decreases in size from the first side to the second side along the second direction of the crossbeam support frame 2. The gradually decreasing structure not only facilitates the quick positioning of the limiting pin, but also facilitates the engagement of the I-shaped pin. In addition, the side of the opening of the limiting hole is provided with an inlet arc to ensure that the limiting pin can smoothly enter the limiting hole.

[0055] In some embodiments, there are multiple limiting pins and limiting holes, and the limiting pins and limiting holes are connected one-to-one. Multiple limiting pins and limiting holes can further improve the tightening effect on the chassis cover 4. In addition, the limiting holes are located in the middle of the crossbeam support frame 2 along the first direction, and the locking pin 222 and the intrusion switch 23 are located between two adjacent limiting holes in the first direction. This arrangement is to ensure that the chassis cover 4 can be effectively limited on both sides of the cover lock 42, and further improve the pressure contact reliability between the chassis cover 4 and the intrusion switch 23.

[0056] In some embodiments, referring to Figures 2(a) and 2(b), the crossbeam support frame 2 is further provided with crossbeam mounting nails 2110 at both ends along the first direction, and the extension direction of the crossbeam mounting nails 2110 is parallel to the first direction; the side plate of the chassis base 1 is also provided with a crossbeam mounting groove 11, and the crossbeam mounting nails 2110 can be inserted into the crossbeam mounting groove 11 and engaged with the crossbeam mounting groove 11 along the second direction. The opening of the crossbeam mounting groove 11 is provided with a rounded chamfer to facilitate the entry of the crossbeam mounting nails 2110 into the crossbeam mounting groove 11. Specifically, the crossbeam support frame 2 and the chassis base 1 can be fixed by a snap-fit ​​assembly on the one hand, and by the cooperation of the crossbeam mounting nails 2110 on the crossbeam support frame 2 and the crossbeam mounting groove 11 on the chassis base 1 on the other hand, to achieve accurate positioning of the crossbeam support frame 2 and the chassis base 1, which can improve the positional accuracy and installation efficiency of the crossbeam support frame 2 and ensure that the elastic snap-fit ​​assembly can be successfully engaged and fixed with the chassis base 1.

[0057] In some implementation methods, please refer to Figure 8It also includes an electrical component 3, which can be a GPU (Graphics Processing Unit) module. The electrical component 3 is installed inside the chassis base 1, and electrical component limiting pins 31 are provided at both ends along the second direction. The crossbeam support frame 2 is also provided with an electrical component limiting groove 217 on at least one side along the second direction. The opening of the electrical component limiting groove 217 faces the chassis cover 4. The electrical component limiting pins 31 can be inserted into the electrical component limiting groove 217 and engage with the electrical component limiting groove 217 along the first direction. The opening of the electrical component limiting groove 217 is provided with a rounded chamfer to facilitate the entry of the electrical component limiting pins 31 into the electrical component limiting groove 217. With the above configuration, the crossbeam support frame 2 not only serves to limit and lock the chassis cover 4, but also effectively supports the electrical components 3. The opening of the electrical component limiting groove 217 faces the chassis cover 4, and the electrical components 3 are installed from top to bottom. The electrical component limiting groove 217 can quickly position the electrical component limiting pins 31 and fix them in the first and second directions, ensuring the reliability of the electrical components 3. Simultaneously, it reduces the need for support structures for the electrical components 3 in related technologies, saving space and reducing manufacturing costs. Furthermore, the crossbeam support frame 2 should also be provided with electrical component fixing holes 218, used to secure the electrical components 3 after the electrical component limiting pins 31 are engaged in the electrical component limiting groove 217 of the crossbeam support frame 2, thereby fixing the electrical components 3 in the height direction.

[0058] In some embodiments, the electrical component 3 is further provided with electrical component telescopic pins 32 at both ends, and the crossbeam support frame 2 should also be provided with electrical component fixing holes 218, so that after the electrical component limiting pin 31 of the electrical component 3 is inserted into the electrical component limiting groove 217 of the crossbeam support frame 2, the electrical component telescopic pin 32 can automatically enter the electrical component fixing hole 218 and limit the electrical component 3, thereby fixing the electrical component 3 in the height direction. When disassembling the electrical component 3, the electrical component 3 can be pulled upward in the height direction by force. With this setting, the electrical component 3 can be disassembled and assembled without tools. Furthermore, the upper part of the electrical component 3 is also provided with an electrical component handle 33, which facilitates the picking up and disassembling of the electrical component 3.

[0059] In some embodiments, the crossbeam support frame 2 includes a main crossbeam support 21 and a platform support 22. The main crossbeam support 21 spans across the chassis base 1, and the platform support 22 is detachably mounted on the side of the middle portion of the main crossbeam support 21. The locking pin 222 and the intrusion switch 23 are both located on the platform support 22. Furthermore, the extension direction of the platform support 22 is perpendicular to the extension direction of the main crossbeam support 21. This arrangement, by separating the main crossbeam support 21 and the platform support 22, improves the positional flexibility of the platform support 22, accommodating different types of chassis covers 4. Additionally, the platform support 22 is installed on the side of the main crossbeam support 21 away from the second direction so that during the installation of the chassis cover 4, the cover lock 42 can first move to the position of the platform support 22, facilitating its engagement with the locking pin 222 and the intrusion switch 23, and preventing the main crossbeam support 21 from interfering with the translation of the cover lock 42.

[0060] In some implementation methods, please refer to Figure 6 The crossbeam support frame 2 includes a top plate and a side plate, which can be an integral structure formed by bending the plate. Both the top plate and the side plate extend along the first direction. The platform bracket 22 is set on the side plate. The top plate is parallel to the chassis cover 4, that is, the top plate extends along the first direction and the second direction. The side plate is set perpendicular to the top plate, that is, the side plate extends along the first direction and the height direction. The side plate is provided with at least two mounting edges 2112, which are also formed by bending the side plate. The platform bracket 22 is detachably set between adjacent mounting edges 2112. The mounting edge 2112 can be provided with a first platform bracket fixing hole 211, which is a countersunk hole to facilitate screwing in. Furthermore, the crossbeam support frame 2 also includes end plates, which are located at both ends of the crossbeam support frame 2 along the first direction. The crossbeam mounting nails 2110 are located on the end plates, and the end plates are provided with movable buckle through holes 213 for the buckle protrusions of the movable buckle 24 to extend out. When the crossbeam support frame 2 is installed in place, the movable buckle through holes 213 correspond to the positions of the buckle limiting grooves 12.

[0061] In some embodiments, the main beam support 21 is provided with multiple mounting positions, and the platform support 22 can be installed in one of the mounting positions. Each mounting position should be provided with an assembly edge 2112. The platform support 22 can be installed on the assembly edge 2112 of the appropriate mounting position according to the position of the cover lock 42 of the chassis cover 4. This setting is to adapt to chassis cover 4 of different specifications. For example, if the platform support 22 interferes with the electrical components 3 inside the chassis in some cases, the position of the platform support 22 and the cover lock 42 can be adjusted. The structure of the main beam support 21 can be universal, improving the adaptability and reducing the manufacturing cost.

[0062] In some embodiments, the crossbeam support frame 2 further includes an inner reinforcing bracket 27 and an outer reinforcing bracket 28. The inner reinforcing bracket 27 and the outer reinforcing bracket 28 are fixedly mounted on the top plate, and the inner reinforcing bracket 27 and the crossbeam support frame 2, as well as the outer reinforcing bracket 28 and the crossbeam support frame 2, are fixedly connected. By setting the inner reinforcing bracket 27 and the outer reinforcing bracket 28, the overall strength of the crossbeam support frame 2, especially its bending resistance, can be improved, thereby more firmly tightening the chassis cover 4 and preventing the chassis cover 4 from deforming.

[0063] In some embodiments, the beam support frame 2, the inner reinforcing bracket 27, and the outer reinforcing bracket 28 are all sheet metal parts with high bending strength. The inner reinforcing bracket 27 and the outer reinforcing bracket 28 both include a reinforcing plate and a connecting edge. The connecting edge is formed by bending the periphery of the reinforcing plate, that is, the reinforcing plate and the connecting edge are an integral structure. The reinforcing plate is parallel to the top plate, and the connecting edge is fixed to the side plate. Specifically, the beam support frame 2, the inner reinforcing bracket 27, and the outer reinforcing bracket 28 are all stamped with reinforcing ribs to further improve strength.

[0064] In some implementation methods, please refer to Figure 7 The surface height of the platform support 22 is lower than the surface height of the main beam support 21, that is, the surface height of the platform support 22 is lower than the top plate surface height of the main beam support 21. The surface of the platform support 22 is provided with an intrusion switch mounting groove 221, and the intrusion switch 23 is fixed in the intrusion switch mounting groove 221. The locking pin 222 is also provided on the surface of the platform support 22. The height difference between the surface height of the platform support 22 and the surface of the main beam support 21 is to ensure that the intrusion switch 23 can smoothly abut against the top cover lock 42 during the process of the chassis cover 4 being moved into place. At the same time, the locking pin 222 can smoothly enter the top cover lock limiting hole 421 of the top cover lock 42, as shown in Figure 9(c). The locking tongue of the top cover lock 42 swings in the top cover lock limiting hole 421 to achieve locking and unlocking.

[0065] In one specific embodiment, the chassis includes a chassis base 1, a crossbeam support frame 2, a chassis top cover 4, and electrical components 3.

The chassis base 1 contains a crossbeam mounting groove 11, a snap-fit ​​limiting groove 12, and a top cover fixing groove 13. The crossbeam mounting groove 11 is used for installing and fixing the crossbeam mounting nails 2110, which can realize the front-back direction limiting and the lower side limiting of the crossbeam support frame 2. The snap-fit ​​limiting groove 12 is used for fixing the crossbeam movable snap-fit ​​24, which can realize the upper side limiting of the crossbeam support frame 2. The crossbeam mounting groove 11 and the snap-fit ​​limiting groove 12 together realize the front-back direction limiting and the lower side limiting of the crossbeam support frame 2. The upper and lower limits are achieved by using the side wall of the chassis base 1 to limit the horizontal movement of the crossbeam support frame 2; the upper cover fixing groove 13 limits the height of the chassis upper cover 4 and the front side limit in the front and back directions; the crossbeam support frame 2 is mainly used to fix the electrical components 3 and the locking pin 222 and the intrusion switch 23, and mainly includes the crossbeam main bracket 21, platform bracket 22, intrusion switch 23, movable buckle 24, reset elastic component 25, movable buckle cover plate 26, inner reinforcing bracket 27, outer reinforcing bracket 28, first sticker 29 and second sticker 210, which are pasted on the crossbeam support frame 2.

The main beam support 21 includes reinforcing member fixing holes 216 for fixing the inner reinforcing member 27 and the outer reinforcing member 28 to the main beam support 21, giving the beam support frame 2 good strength and meeting the requirements for supporting and fixing the electrical components 3. The main beam support 21 has electrical component limiting grooves 217 and electrical component fixing holes 218 for limiting and fixing the tail end of the electrical components 3. The main beam support 21 has an upper cover limiting part 219, which is used to limit the installation of the upper cover limiting member 43 and prevent the middle part of the chassis upper cover 4 from deforming upward.

[0067] Furthermore, the main crossbeam support 21 has crossbeam mounting nails 2110 on both sides for mounting the crossbeam support frame 2 to the crossbeam mounting slots 11 on both sides of the chassis base 1. The platform support 22 has an intrusion switch 23 fixing slot, which allows for interference fit assembly of the intrusion switch 23.

The platform support 22 has fixing holes for fixing the platform support 22 to the main crossbeam support 21. The intrusion switch 23 is a columnar intrusion switch 23. When the intrusion switch 23 is compressed downwards, the circuit is in an open state; when the intrusion switch 23 is not compressed, the circuit is in a contact and conducting state. There is one movable latch 24 on each side, and four reset elastic components 25. Each reset elastic component 25 can be a reset spring. There is one movable latch cover plate 26 on each side. Both movable latches 24 at the left and right ends have operating handles. By moving the operating handles and resetting the reset elastic components 25, the crossbeam support frame 2 is fixed and the movable latches 24 are disengaged. The reset elastic components 25 are used to reset the movable latches 24 and maintain their extended state. The movable latch cover plate 26 is a sheet metal part used for protection and limiting of the movable latches 24, and is fixed with screws. The electrical component 3 has two electrical component limiting pins 31 and two electrical component telescopic pins 32. The electrical component limiting pins 31 are installed in the electrical component limiting grooves 217 of the crossbeam support frame 2, and the electrical component telescopic pins 32 extend into the electrical component fixing holes 218 to limit the electrical component 3. The chassis cover 4 includes a chassis cover body 41, a cover lock 42, a cover limiting member 43, and a cover mounting post 44. The cover lock 42 includes a cover lock limiting hole 421, which is used to achieve complete fixation after being locked with the locking pin 222 on the crossbeam support frame 2, preventing the chassis cover 4 from being arbitrarily pulled back and opened when not unlocked.

[0068] The installation process of the chassis includes the following steps: riveting the main beam support 21, inner reinforcing support 27, and outer reinforcing support 28 together; riveting the platform support 22 to the main beam support 21; installing one side movable buckle 24 into the main beam support 21, placing one side reset elastic component 25 and movable buckle cover plate 26 together into the main beam support 21, and locking them with screws; installing the other side movable buckle 24, reset elastic component 25, and movable buckle cover plate 26 in the same way; installing the intrusion switch 23, and snapping the intrusion switch 23 into the intrusion switch 23 fixing slot of the platform support 22; installation of the beam support frame 2: moving both hands to the operating position of the sliding buckle of the beam support frame 2, i.e., the buckle hole 241 of the movable buckle 24, so that the movable buckle 24 is inserted into the chassis base 1 in the compressed state of the reset elastic component 25; installing the beam mounting nails 2110 on both sides of the beam support frame 2 into the beam mounting slots 11 on both sides of the chassis base 1.
