Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] Please refer to the following: Figure 1 and Figure 2 The chassis provided in the embodiments of this application will now be described. The chassis includes a housing 100, a cover 200, a pull rod 300, and a handle 400; as shown... Figure 3 and Figure 8 As shown, the inner side of the box 100 is provided with a protruding limiting member 101; the box cover 200 closes onto the box 100; as Figure 5 As shown, the lid 200 has a first end 201 and a second end 202 disposed opposite to each other. The first end 201 is rotatably connected to the body 100. The pull rod 300 is slidably connected to the lid 200. The pull rod 300 is located on the side of the lid 200 near the body 100 and near the second end 202 of the lid 200. The pull rod 300 is provided with a locking groove 301. The pull rod 300 has a first position and a second position. In the first position, the limiting member 101 is engaged in the locking groove 301. In the second position, the limiting member 101 is separated from the locking groove 301. One end of the handle 400 passes through the lid 200 and abuts against the pull rod 300. Figure 11The other end of the handle 400 is the drive end 401. The middle part of the handle 400 is rotatably connected to the cover 200. Pulling the drive end 401 can push the lever 300 to switch between the first position and the second position.

[0042] Compared with the prior art, the chassis provided in this application, by setting a handle 400, not only can push the pull rod 300 to switch between a first position and a second position to lock and unlock the chassis cover 200, but it also facilitates user operation. By pulling the chassis cover 200 with the handle 400, no additional tools are needed, making the opening and closing of the chassis cover 200 more convenient and significantly improving the user experience of the chassis. One end of the chassis cover 200 is rotatably connected to the chassis body 100. After the chassis cover 200 is opened, it will not completely detach from the chassis body 100, reducing the possibility of the chassis cover 200 being lost or damaged, and also facilitating the user's maintenance and upgrade of the internal hardware.

[0043] In one embodiment of this application, please refer to the following: Figure 5 and Figure 6 The lid 200 is provided with a bracket 203, and the bracket 203 is provided with a rotating shaft 204. The handle 400 is rotatably connected to the rotating shaft 204. A torsion spring 205 is sleeved on the rotating shaft 204. The long torsion arm of the torsion spring 205 abuts against the lid 200, and the short torsion arm of the torsion spring 205 abuts against the handle 400.

[0044] In this embodiment, by providing the bracket 203, the rotating shaft 204, and the torsion spring 205, stable support and rebound force can be provided for the operation of the handle 400. When the user pulls the drive end 401 of the handle 400, the torsion spring 205 deforms and stores elastic potential energy; when the handle 400 is released, the torsion spring 205 returns to its original shape, pushing the handle 400 back to its initial position. This design not only improves the convenience of operation but also ensures that the handle 400 has a good reset function during use, thereby improving the overall reliability and service life of the chassis.

[0045] In one embodiment of this application, please refer to the following: Figure 5 and Figure 10 The lid 200 is provided with a guide block 206, and the pull rod 300 is provided with a slide groove 302. The guide block 206 is slidably connected in the slide groove 302.

[0046] In this embodiment, by setting the guide block 206 and the slide groove 302, not only is the sliding connection between the pull rod 300 and the cover 200 achieved, but the movement trajectory of the pull rod 300 is also ensured, allowing the pull rod 300 to smoothly move back and forth between the first and second positions. The cooperative design of the guide block 206 and the slide groove 302 effectively reduces the shaking or jamming that may occur during the sliding process of the pull rod 300, thereby improving the accuracy and stability of the operation.

[0047] In one embodiment of this application, please refer to the following: Figure 2 and Figure 5 The chassis also includes a tension spring 500, one end of which is connected to the bracket 203, and the other end of which is connected to the pull rod 300.

[0048] In this embodiment, the reset performance of the pull rod 300 is further enhanced by adding a tension spring 500. When the pull rod 300 returns from the second position to the first position, the tension spring 500 provides additional traction to assist the pull rod 300 in quickly and accurately returning to its initial state. This design not only improves operational efficiency but also reduces the force required by the user, thereby optimizing the user experience.

[0049] In one embodiment of this application, please refer to the following: Figure 1 and Figure 4 The chassis also includes fasteners 600, which are detachably connected to handles 400 and cover 200.

[0050] In this embodiment, when the pull rod 300 is locked, the fastener 600 can fix the handle 400 to the cover 200 together, preventing the handle 400 from moving arbitrarily due to external force and causing the cover 200 to be accidentally unlocked, thereby improving the stability of the chassis during transportation or use. When the cover 200 needs to be unlocked, simply remove the fastener 600 and pull the handle 400.

[0051] Specifically, the fastener 600 can be a screw, which is used to fix and separate the handle 400 from the cover 200 by tightening and loosening the screw. The use of screws is not only simple to operate but also provides a secure connection, effectively preventing loosening caused by vibration or other external forces. Furthermore, the removable design of the screws facilitates chassis maintenance and component replacement.

[0052] In one embodiment of this application, please refer to Figure 4 A spring 700 is fitted on the fastener 600. One end of the spring 700 abuts against the fastener 600, and the other end of the spring 700 abuts against the handle 400.

[0053] In this embodiment, by setting a spring 700, when it is necessary to remove the fastener 600, simply loosen the fastener 600 and then use the elastic force of the spring 700 to pop the fastener 600 out. No additional tools are needed, which simplifies the operation process and improves the convenience of operation.

[0054] In one embodiment of this application, please refer to the following: Figure 2 and Figure 6The lever 300 is provided with a first abutting part 303, and one end of the handle 400 forms a second abutting part 402, with the first abutting part 303 abutting with the second abutting part 402.

[0055] In this embodiment, through the cooperation of the first ground contact portion and the second abutment portion 402, when the drive end 401 of the handle 400 is pulled, the contact between the first abutment portion 303 and the second abutment portion 402 ensures effective force transmission, allowing the pull rod 300 to smoothly switch between the first position and the second position. This design not only improves the reliability of operation but also reduces jamming or wear caused by uneven force transmission, thereby extending the service life of the chassis.

[0056] In one embodiment of this application, please refer to the following: Figure 2 and Figure 10 Perpendicular to the moving direction of the pull rod 300, the edge of the locking groove 301 is provided with a first guide surface 304.

[0057] In this embodiment, the design of the first guide surface 304 guides the limiting member 101 into the locking groove 301. When the lid 200 is on the box body 100, the first guide surface 304 contacts the limiting member 101, pressing down the lid 200 and generating a horizontal force that pushes the pull rod 300 to move, allowing the limiting member 101 to slide smoothly into the locking groove 301. The lid 200 can be locked without pulling the handle 400, improving the convenience of operation.

[0058] In one embodiment of this application, please refer to the following: Figure 2 and Figure 10 Along the moving direction of the pull rod 300, the edge of the locking groove 301 is provided with a second guide surface 305.

[0059] In this embodiment, the second guide surface 305 provides auxiliary guidance for the process of the limiting member 101 disengaging from the locking groove 301. When the pull rod 300 moves to the second position, the limiting member 101 gradually slides out of the locking groove 301 under the action of the second guide surface 305, avoiding operational difficulties or component damage caused by excessive resistance. This design effectively reduces the force required for the user to unlock the cover 200, while reducing the risk caused by misoperation, and further optimizing the overall operational smoothness of the chassis.

[0060] In one embodiment of this application, please refer to the following: Figure 7 and Figure 9 The lid 200 has a hollowed-out portion 207, which is close to the first end 201 of the lid 200, so that the lid 200 forms a pivot 208 at the first end 201; the box body 100 is provided with a pivot seat 800, and the pivot 208 is rotatably connected to the pivot seat 800.

[0061] In this embodiment, a rotating shaft 208 is formed by providing a hollow portion 207 on the cover 200, making the rotating shaft 208 and the cover 200 an integral structure. This not only simplifies the overall structural design of the chassis but also effectively reduces production costs. The cooperative design between the rotating shaft 208 and the rotating shaft seat 800 ensures the stability and smoothness of the cover 200 during rotation, avoiding operational inconvenience caused by friction or jamming. In addition, the design of the hollow portion 207 can also reduce the weight of the cover 200 to a certain extent, making it easier for users to open or close the cover 200, further improving the user experience.

[0062] In one embodiment of this application, the cover 200 is located at the bottom of the chassis, such as... Figure 1 As shown, the case cover 200 is equipped with feet 209. The design of the feet 209 can effectively improve the stability and anti-slip performance of the case. When the case is placed on a smooth surface, the feet 209 increase the friction to prevent the case from shifting due to external forces or vibrations, thereby ensuring the safety of the case during use.

[0063] The usage process of the chassis provided in this application embodiment is as follows:

[0064] Open the lid 200 and first remove the fastener 600. The spring force of the spring 700 will assist the fastener 600 in popping out, making operation easier. Next, pull the drive end 401 of the handle 400. The handle 400 rotates around the rotating shaft 204, causing the torsion spring 205 to deform. The second abutment part 402 of the handle 400 contacts the first abutment part 303 on the pull rod 300 and pushes the pull rod 300. The pull rod 300 moves smoothly with the cooperation of the guide block 206 and the slide groove 302, switching from the first position to the second position. During this process, the second guide surface 305 at the edge of the locking groove 301 guides the limiting member 101 to gradually slide out of the locking groove 301, unlocking the lid 200. When the lid 200 needs to be closed, press the lid 200 down. The first guide surface 304 on the edge of the lock groove 301 guides the limiting member 101 to slide into the lock groove 301. The pull rod 300 returns from the second position to the first position. After releasing the handle 400, the torsion spring 205 resets the handle 400. Then, the fastener 600 is reinstalled to fix the handle 400 and the lid 200.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
